  • Can't focus fancybox iframe input

    - by bswinnerton
    So I'm using fancybox to load up a login iframe, and I would like it onComplete to bring focus to the username field. If someone could take a look at this code and let me know what's wrong, that'd be great. Gracias. /* Function to resize the height of the fancybox window */ (function($){ $.fn.resize = function(width, height) { if (!width || (width == "inherit")) inner_width = parent.$("#fancybox-inner").width(); if (!height || (height == "inherit")) inner_height = parent.$("#fancybox-inner").height(); inner_width = width; outer_width = (inner_width + 14); inner_height = height; outer_height = (inner_height + 14); parent.$("#fancybox-inner").css({'width':inner_width, 'height':inner_height}); parent.$("#fancybox-outer").css({'width':outer_width, 'height':outer_height}); } })(jQuery); $(document).ready(function(){ var pasturl = parent.location.href; $("a.iframe#register").fancybox({ 'transitionIn' : 'fade', 'transitionOut' : 'fade', 'speedIn' : 600, 'speedOut' : 350, 'width' : 450, 'height' : 385, 'scrolling' : 'no', 'autoScale' : false, 'autoDimensions' : false, 'overlayShow' : true, 'overlayOpacity' : 0.7, 'padding' : 7, 'hideOnContentClick': false, 'titleShow' : false, 'onStart' : function() { $.fn.resize(450,385); }, 'onComplete' : function() { $("#realname").focus(); }, 'onClosed' : function() { $(".warningmsg").hide(); $(".errormsg").hide(); $(".successfulmsg").hide(); } }); $("a.iframe#login").fancybox({ 'transitionIn' : 'fade', 'transitionOut' : 'fade', 'speedIn' : 600, 'speedOut' : 350, 'width' : 400, 'height' : 250, 'scrolling' : 'no', 'autoScale' : false, 'overlayShow' : true, 'overlayOpacity' : 0.7, 'padding' : 7, 'hideOnContentClick': false, 'titleShow' : false, 'onStart' : function() { $.fn.resize(400,250); }, 'onComplete' : function() { $("#login_username").focus(); }, 'onClosed' : function() { $(".warningmsg").hide(); $(".errormsg").hide(); $(".successfulmsg").hide(); } }); $("#register").click(function() { $("#login_form").hide(); $(".registertext").hide(); $.fn.resize(450,385); $("label").addClass("#register_form label"); }); $("#login").click(function() { $.fn.resize(400,250); $("label").addClass("#login_form label"); }); $("#register_form").bind("submit", function() { $(".warningmsg").hide(); $(".errormsg").hide(); $(".successfulmsg").hide(); if ($("#realname").val().length < 1 || $("#password").val().length < 1 || $("#username").val().length < 1) { $("#no_fields").addClass("warningmsg").show().resize(inherit,405); return false; } if ($("#password").val() != $("#password2").val()) { $("#no_pass_match").addClass("errormsg").show().resize(); return false; } $.fancybox.showActivity(); $.post( "../../admin/users/create_submit.php", { realname:$('#realname').val(), email:$('#email').val(), username:$('#username').val(), password:MD5($('#password').val()), rand:Math.random() } ,function(data){ if(data == "OK"){ $(".registerbox").hide(); $.fancybox.hideActivity(); $.fn.resize(inherit,300); $("#successful_login").addClass("successfulmsg").show(); } else if(data == "user_taken"){ $.fancybox.hideActivity(); $("#user_taken").addClass("errormsg").show().resize(inherit,405); $("#username").val(""); } else { $.fancybox.hideActivity(); document.write("Well, that was weird. Give me a shout at [email protected]."); } return false; }); return false; }); $("#login_form").bind("submit", function() { $(".warningmsg").hide(); $(".errormsg").hide(); $(".successfulmsg").hide(); if ($("#login_username").val().length < 1 || $("#login_password").val().length < 1) { $("#no_fields").addClass("warningmsg").show().resize(inherit,280); return false; } $.fancybox.showActivity(); $.post( "../../admin/users/login_submit.php", { username:$('#login_username').val(), password:MD5($('#login_password').val()), rand:Math.random() } ,function(data){ if(data == "authenticated"){ $(".loginbox").hide(); $(".registertext").hide(); $.fancybox.hideActivity(); $("#successful_login").addClass("successfulmsg").show(); parent.document.location.href=pasturl; } else if(data == "no_user"){ $.fancybox.hideActivity(); $("#no_user").addClass("errormsg").show().resize(); $("#login_username").val(""); $("#login_password").val(""); } else if(data == "wrong_password"){ $.fancybox.hideActivity(); $("#wrong_password").addClass("warningmsg").show().resize(); $("#login_password").val(""); } else { $.fancybox.hideActivity(); document.write("Well, that was weird."); } return false; }); return false; }); }); And here is the HTML: <p><a class="iframe" id="login" href="/login/">Login</a></p>

  • SOA Suite Integration: Part 1: Building a Web Service

    - by Anthony Shorten
    Over the next few weeks I will be posting blog entries outlying the SOA Suite integration of the Oracle Utilities Application Framework. This will illustrate how easy it is to integrate by providing some samples. I will use a consistent set of features as examples. The examples will be simple and while will not illustrate ALL the possibilities it will illustrate the relative ease of integration. Think of them as a foundation. You can obviously build upon them. Now, to ease a few customers minds, this series will certainly feature the latest version of SOA Suite and the latest version of Oracle Utilities Application Framework but the principles will apply to past versions of both those products. So if you have Oracle SOA Suite 10g or are a customer of Oracle Utilities Application Framework V2.1 or above most of what I will show you will work with those versions. It is just easier in Oracle SOA Suite 11g and Oracle Utilities Application Framework V4.x. This first posting will not feature SOA Suite at all but concentrate on the capability for the Oracle Utilities Application Framework to create Web Services you can use for integration. The XML Application Integration (XAI) component of the Oracle Utilities Application Framework allows product objects to be exposed as XML based transactions or as Web Services (or both). XAI was written before Web Services became fashionable and has allowed customers of our products to provide a consistent interface into and out of our product line. XAI has been enhanced over the last few years to take advantages of the maturing landscape of Web Services in the market place to a point where it now easier to integrate to SOA infrastructure. There are a number of object types that can be exposed as Web Services: Maintenance Objects – These are the lowest level objects that can be exposed as Web Services. Customers of past versions of the product will be familiar with XAI services based upon Maintenance Objects as they used to be the only method of generating Web Services. These are still supported for background compatibility but are starting to become less popular as they were strict in their structure and were solely attribute based. To generate Maintenance Object based Web Services definition you need to use the XAI Schema Editor component. Business Objects – In Oracle Utilities Application Framework V2.1 we introduced the concept of Business Objects. These are site or industry specific objects that are based upon Maintenance Objects. These allow sites to respecify, in configuration, the structure and elements of a Maintenance Object and other Business Objects (they are true objects with support for inheritance, polymorphism, encapsulation etc.). These can be exposed as Web Services. Business Services – As with Business Objects, we introduced Business Services in Oracle Utilities Application Framework V2.1 which allowed applications services and query zones to be expressed as custom services. These can then be exposed as Web Services via the Business Service definition. Service Scripts - As with Business Objects and Business Services, we introduced Service Scripts in Oracle Utilities Application Framework V2.1. These allow services and/objects to be combined into complex objects or simply expose common routines as callable scripts. These can also be defined as Web Services. For the purpose of this series we will restrict ourselves to Business Objects. The techniques can apply to any of the objects discussed above. Now, lets get to the important bit of this blog post, the creation of a Web Service. To build a Business Object, you first logon to the product and navigate to the Administration Menu by selecting the Admin Menu from the Menu action on left top of the screen (next to Home). A popup menu will appear with the menu’s available. If you do not see the Admin menu then you do not have authority to use it. Here is an example: Navigate to the B menu and select the + symbol next to the Business Object menu item. This indicates that you want to ADD a new Business Object. This menu will appear if you are running Alphabetic mode in your installation (I almost forgot that point). You will be presented with the Business Object maintenance screen. You will fill out the following on the first tab (at a minimum): Business Object – The name of the Business Object. Typically you will make it descriptive and also prefix with CM to denote it as a customization (you can easily find it if you prefix it). As I running this on my personal copy of the product I will use my initials as the prefix and call the sample Web Service “AS-User”. Description – A short description of the object to tell others what it is used for. For my example, I will use “Anthony Shorten’s User Object”. Detailed Description – You can add a long description to help other developers understand your object. I am just going to specify “Anthony Shorten’s Test Object for SOA Suite Integration”. Maintenance Object – As this Business Service is going to be based upon a Maintenance Object I will specify the desired Maintenance Object. In this example, I have decided to use the Framework object USER. Now, I chose this for a number of reasons. It is meaningful, simple and is across all our product lines. I could choose ANY maintenance object I wished to expose (including any custom ones, if I had them). Parent Business Object – If I was not using a Maintenance Object but building a child Business Object against another Business Object, then I would specify the Parent Business Object here. I am not using Parent’s so I will leave this blank. You either use Parent Business Object or Maintenance Object not both. Application Service – Business Objects like other objects are subject to security. You can attach an Application Service to an object to specify which groups of users (remember services are attached to user groups not users) have appropriate access to the object. I will use a default service provided with the product, F1-DFLTS ,as this is just a demonstration so I do not have to be too sophisticated about security. Instance Control – This allows the object to create instances in its objects. You can specify a Business Object purely to hold rules. I am being simple here so I will set it to Allow New Instances to allow the Business Object to be used to create, read, update and delete user records. The rest of the tab I will leave empty as I want this to be a very simple object. Other options allow lots of flexibility. The contents should look like this: Before saving your work, you need to navigate to the Schema tab and specify the contents of your object. I will save some time. When you create an object the schema will only contain the basic root elements of the object (in fact only the schema tag is visible). When you go to the Schema Tab, on the dashboard you will see a BO Schema zone with a solitary button. This will allow you to Generate the Schema for you from our metadata. Click on the Generate button to generate a basic schema from the metadata. You will now see a Schema with the element tags and references to the metadata of the Maintenance object (in the mapField attribute). I could spend a while outlining all the ways you can change the schema with defaults, formatting, tagging etc but the online help has plenty of great examples to illustrate this. You can use the Schema Tips zone in the for more details of the available customizations. Note: The tags are generated from the language pack you have installed. The sample is English so the tags are in English (which is the base language of all installations). If you are using a language pack then the tags will be generated in the language of the user that generated the object. At this point you can save your Business Object by pressing the Save action. At this point you have a basic Business Object based on the USER maintenance object ready for use but it is not defined as a Web Service yet. To do this you need to define the newly created Business Object as an XAI Inbound Service. The easiest and quickest way is to select + off the XAI Inbound Service off the context menu on the Business Object maintenance screen. This will prepopulate the service definition with the following: Adapter – This will be set to Business Adaptor. This indicates that the service is either Business Object, Business Service or Service Script based. Schema Type – Whether the object is a Business Object, Business Service or Service Script. In this case it is a Business Object. Schema Name – The name of the object. In this case it is the Business Object AS-User. Active – Set to Yes. This means the service is available upon startup automatically. You can enable and disable services as needed. Transaction Type – A default transaction type as this is Business Object Service. More about this in later postings. In our case we use the default Read. This means that if we only specify data and not a transaction type then the product will assume you want to issue a read against the object. You need to fill in the following: XAI Inbound Service – The name of the Web Service. Usually people use the same name as the underlying object , in the case of this example, but this can match your sites interfacing standards. By the way you can define multiple XAI Inbound Services/Web Services against the same object if you want. Description and Detail Description – Documentation for your Web Service. I just supplied some basic documentation for this demonstration. You can now save the service definition. Note: There are lots of other options on this screen that allow for behavior of your service to be specified. I will leave them blank for now. When you save the service you are issued with two new pieces of information. XAI Inbound Service Id is a randomly generated identifier used internally by the XAI Servlet. WSDL URL is the WSDL standard URL used for integration. We will take advantage of that in later posts. An example of the definition is shown below: Now you have defined the service but it will only be available when the next server restart or when you flush the data cache. XAI Inbound Services are cached for performance so the cache needs to be told of this new service. To refresh the cache you can use the Admin –> X –> XAI Command menu item. From the command dropdown select Refresh Registry and press Send Command. You will see an XML of the command sent to the server (the presence of the XML means it is finished). If you have an error around the authorization, then check your default user and password settings on the XAI Options menu item. Be careful with flushing the cache as the cache is shared (unless of course you are the only Web Service user on the system – In that case it only affects you). The Web Service is NOW available to be used. To perform a simple test of your new Web Service, navigate to the Admin –> X –> XAI Submission menu item. You will see an open XML request tab. You need to type in the request XML you want to test in the Main tab. The first tag is the XAI Inbound Service Name and the elements are as per your schema (minus the schema tag itself as that is only used internally). My example is as follows (I want to return the details of user SYSUSER) – Remember to close tags. Hitting the Save button will issue the XML and return the response according to the Business Object schema. Now before you panic, you noticed that it did not ask for credentials. It propagates the online credentials to the service call on this function. You now have a Web Service you can use for integration. We will reuse this information in subsequent posts. The process I just described can be used for ANY object in the system you want to expose. This whole process at a minimum can take under a minute. Obviously I only showed the basics but you can at least get an appreciation of the ease of defining a Web Service (just by using a browser). The next posts now build upon this. Hope you enjoyed the post.

  • The Art of Productivity

    - by dwahlin
    Getting things done has always been a challenge regardless of gender, age, race, skill, or job position. No matter how hard some people try, they end up procrastinating tasks until the last minute. Some people simply focus better when they know they’re out of time and can’t procrastinate any longer. How many times have you put off working on a term paper in school until the very last minute? With only a few hours left your mental energy and focus seem to kick in to high gear especially as you realize that you either get the paper done now or risk failing. It’s amazing how a little pressure can turn into a motivator and allow our minds to focus on a given task. Some people seem to specialize in procrastinating just about everything they do while others tend to be the “doers” who get a lot done and ultimately rise up the ladder at work. What’s the difference between these types of people? Is it pure laziness or are other factors at play? I think that some people are certainly more motivated than others, but I also think a lot of it is based on the process that “doers” tend to follow - whether knowingly or unknowingly. While I’ve certainly fought battles with procrastination, I’ve always had a knack for being able to get a lot done in a relatively short amount of time. I think a lot of my “get it done” attitude goes back to the the strong work ethic my parents instilled in me at a young age. I remember my dad saying, “You need to learn to work hard!” when I was around 5 years old. I remember that moment specifically because I was on a tractor with him the first time I heard it while he was trying to move some large rocks into a pile. The tractor was big but so were the rocks and my dad had to balance the tractor perfectly so that it didn’t tip forward too far. It was challenging work and somewhat tedious but my dad finished the task and taught me a few important lessons along the way including persistence, the importance of having a skill, and getting the job done right without skimping along the way. In this post I’m going to list a few of the techniques and processes I follow that I hope may be beneficial to others. I blogged about the general concept back in 2009 but thought I’d share some updated information and lessons learned since then. Most of the ideas that follow came from learning and refining my daily work process over the years. However, since most of the ideas are common sense (at least in my opinion), I suspect they can be found in other productivity processes that are out there. Let’s start off with one of the most important yet simple tips: Start Each Day with a List. Start Each Day with a List What are you planning to get done today? Do you keep track of everything in your head or rely on your calendar? While most of us think that we’re pretty good at managing “to do” lists strictly in our head you might be surprised at how affective writing out lists can be. By writing out tasks you’re forced to focus on the most important tasks to accomplish that day, commit yourself to those tasks, and have an easy way to track what was supposed to get done and what actually got done. Start every morning by making a list of specific tasks that you want to accomplish throughout the day. I’ll even go so far as to fill in times when I’d like to work on tasks if I have a lot of meetings or other events tying up my calendar on a given day. I’m not a big fan of using paper since I type a lot faster than I write (plus I write like a 3rd grader according to my wife), so I use the Sticky Notes feature available in Windows. Here’s an example of yesterday’s sticky note: What do you add to your list? That’s the subject of the next tip. Focus on Small Tasks It’s no secret that focusing on small, manageable tasks is more effective than trying to focus on large and more vague tasks. When you make your list each morning only add tasks that you can accomplish within a given time period. For example, if I only have 30 minutes blocked out to work on an article I don’t list “Write Article”. If I do that I’ll end up wasting 30 minutes stressing about how I’m going to get the article done in 30 minutes and ultimately get nothing done. Instead, I’ll list something like “Write Introductory Paragraphs for Article”. The next day I may add, “Write first section of article” or something that’s small and manageable – something I’m confident that I can get done. You’ll find that once you’ve knocked out several smaller tasks it’s easy to continue completing others since you want to keep the momentum going. In addition to keeping my tasks focused and small, I also make a conscious effort to limit my list to 4 or 5 tasks initially. I’ve found that if I list more than 5 tasks I feel a bit overwhelmed which hurts my productivity. It’s easy to add additional tasks as you complete others and you get the added benefit of that confidence boost of knowing that you’re being productive and getting things done as you remove tasks and add others. Getting Started is the Hardest (Yet Easiest) Part I’ve always found that getting started is the hardest part and one of the biggest contributors to procrastination. Getting started working on tasks is a lot like getting a large rock pushed to the bottom of a hill. It’s difficult to get the rock rolling at first, but once you manage to get it rocking some it’s really easy to get it rolling on its way to the bottom. As an example, I’ve written 100s of articles for technical magazines over the years and have really struggled with the initial introductory paragraphs. Keep in mind that these are the paragraphs that don’t really add that much value (in my opinion anyway). They introduce the reader to the subject matter and nothing more. What a waste of time for me to sit there stressing about how to start the article. On more than one occasion I’ve spent more than an hour trying to come up with 2-3 paragraphs of text.  Talk about a productivity killer! Whether you’re struggling with a writing task, some code for a project, an email, or other tasks, jumping in without thinking too much is the best way to get started I’ve found. I’m not saying that you shouldn’t have an overall plan when jumping into a task, but on some occasions you’ll find that if you simply jump into the task and stop worrying about doing everything perfectly that things will flow more smoothly. For my introductory paragraph problem I give myself 5 minutes to write out some general concepts about what I know the article will cover and then spend another 10-15 minutes going back and refining that information. That way I actually have some ideas to work with rather than a blank sheet of paper. If I still find myself struggling I’ll write the rest of the article first and then circle back to the introductory paragraphs once I’m done. To sum this tip up: Jump into a task without thinking too hard about it. It’s better to to get the rock at the top of the hill rocking some than doing nothing at all. You can always go back and refine your work.   Learn a Productivity Technique and Stick to It There are a lot of different productivity programs and seminars out there being sold by companies. I’ve always laughed at how much money people spend on some of these motivational programs/seminars because I think that being productive isn’t that hard if you create a re-useable set of steps and processes to follow. That’s not to say that some of these programs/seminars aren’t worth the money of course because I know they’ve definitely benefited some people that have a hard time getting things done and staying focused. One of the best productivity techniques I’ve ever learned is called the “Pomodoro Technique” and it’s completely free. This technique is an extremely simple way to manage your time without having to remember a bunch of steps, color coding mechanisms, or other processes. The technique was originally developed by Francesco Cirillo in the 80s and can be implemented with a simple timer. In a nutshell here’s how the technique works: Pick a task to work on Set the timer to 25 minutes and work on the task Once the timer rings record your time Take a 5 minute break Repeat the process Here’s why the technique works well for me: It forces me to focus on a single task for 25 minutes. In the past I had no time goal in mind and just worked aimlessly on a task until I got interrupted or bored. 25 minutes is a small enough chunk of time for me to stay focused. Any distractions that may come up have to wait until after the timer goes off. If the distraction is really important then I stop the timer and record my time up to that point. When the timer is running I act as if I only have 25 minutes total for the task (like you’re down to the last 25 minutes before turning in your term paper….frantically working to get it done) which helps me stay focused and turns into a “beat the clock” type of game. It’s actually kind of fun if you treat it that way and really helps me focus on a the task at hand. I automatically know how much time I’m spending on a given task (more on this later) by using this technique. I know that I have 5 minutes after each pomodoro (the 25 minute sprint) to waste on anything I’d like including visiting a website, stepping away from the computer, etc. which also helps me stay focused when the 25 minute timer is counting down. I use this technique so much that I decided to build a program for Windows 8 called Pomodoro Focus (I plan to blog about how it was built in a later post). It’s a Windows Store application that allows people to track tasks, productive time spent on tasks, interruption time experienced while working on a given task, and the number of pomodoros completed. If a time estimate is given when the task is initially created, Pomodoro Focus will also show the task completion percentage. I like it because it allows me to track my tasks, time spent on tasks (very useful in the consulting world), and even how much time I wasted on tasks (pressing the pause button while working on a task starts the interruption timer). I recently added a new feature that charts productive and interruption time for tasks since I wanted to see how productive I was from week to week and month to month. A few screenshots from the Pomodoro Focus app are shown next, I had a lot of fun building it and use it myself to as I work on tasks.   There are certainly many other productivity techniques and processes out there (and a slew of books describing them), but the Pomodoro Technique has been the simplest and most effective technique I’ve ever come across for staying focused and getting things done.   Persistence is Key Getting things done is great but one of the biggest lessons I’ve learned in life is that persistence is key especially when you’re trying to get something done that at times seems insurmountable. Small tasks ultimately lead to larger tasks getting accomplished, however, it’s not all roses along the way as some of the smaller tasks may come with their own share of bumps and bruises that lead to discouragement about the end goal and whether or not it is worth achieving at all. I’ve been on several long-term projects over my career as a software developer (I have one personal project going right now that fits well here) and found that repeating, “Persistence is the key!” over and over to myself really helps. Not every project turns out to be successful, but if you don’t show persistence through the hard times you’ll never know if you succeeded or not. Likewise, if you don’t persistently stick to the process of creating a daily list, follow a productivity process, etc. then the odds of consistently staying productive aren’t good.   Track Your Time How much time do you actually spend working on various tasks? If you don’t currently track time spent answering emails, on phone calls, and working on various tasks then you might be surprised to find out that a task that you thought was going to take you 30 minutes ultimately ended up taking 2 hours. If you don’t track the time you spend working on tasks how can you expect to learn from your mistakes, optimize your time better, and become more productive? That’s another reason why I like the Pomodoro Technique – it makes it easy to stay focused on tasks while also tracking how much time I’m working on a given task.   Eliminate Distractions I blogged about this final tip several years ago but wanted to bring it up again. If you want to be productive (and ultimately successful at whatever you’re doing) then you can’t waste a lot of time playing games or on Twitter, Facebook, or other time sucking websites. If you see an article you’re interested in that has no relation at all to the tasks you’re trying to accomplish then bookmark it and read it when you have some spare time (such as during a pomodoro break). Fighting the temptation to check your friends’ status updates on Facebook? Resist the urge and realize how much those types of activities are hurting your productivity and taking away from your focus. I’ll admit that eliminating distractions is still tough for me personally and something I have to constantly battle. But, I’ve made a conscious decision to cut back on my visits and updates to Facebook, Twitter, Google+ and other sites. Sure, my Klout score has suffered as a result lately, but does anyone actually care about those types of scores aside from your online “friends” (few of whom you’ve actually met in person)? :-) Ultimately it comes down to self-discipline and how badly you want to be productive and successful in your career, life goals, hobbies, or whatever you’re working on. Rather than having your homepage take you to a time wasting news site, game site, social site, picture site, or others, how about adding something like the following as your homepage? Every time your browser opens you’ll see a personal message which helps keep you on the right track. You can download my ubber-sophisticated homepage here if interested. Summary Is there a single set of steps that if followed can ultimately lead to productivity? I don’t think so since one size has never fit all. Every person is different, works in their own unique way, and has their own set of motivators, distractions, and more. While I certainly don’t consider myself to be an expert on the subject of productivity, I do think that if you learn what steps work best for you and gradually refine them over time that you can come up with a personal productivity process that can serve you well. Productivity is definitely an “art” that anyone can learn with a little practice and persistence. You’ve seen some of the steps that I personally like to follow and I hope you find some of them useful in boosting your productivity. If you have others you use please leave a comment. I’m always looking for ways to improve.

  • Binding collection indexes to a WPF DataGrid at runtime

    - by bearda
    After trying to develop our own control to display a table of data we stumbled on the WPF toolkit DataGrid and thought we were saved. A couple hours later I'm scratching my head trying to figure out if it can do what we really want it to do. The DataGrid seems to be based on displaying various properties of a single object, where I think I need something that can display a collection's items, I want to display a table of strings with a variable number of rows and a variable number of columns. Each row represents the state of a number of inputs at a given time. The number of samples may change, and the number of inputs may change at runtime. As a result, I can't create a custom object that represents a row with a property for each input. This makes the DataGrid binding more complicated, since I can't bind to a fixed property for each column. I thought I found a workaround for this by binding to ".[" + channelIndex + ]" but it hasn't worked out quite the way I wanted. Right now I have a collection of a collection of strings that represents the two-dimensional array of strings. I'm using ObservableCollection so string change event notifications work, but I can use any collection type needed. It looked like everything was working great until I realized that every row was showing the same line of data. Binding in C# is not my strong suit, so I'm kind of lost on what's going wrong. Is what I'm trying to do overall even possible with the WPF Toolkit DataGrid? using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Windows; using System.Windows.Controls; using System.Windows.Data; using System.Windows.Documents; using System.Windows.Input; using System.Windows.Media; using System.Windows.Media.Imaging; using System.Windows.Navigation; using System.Windows.Shapes; using Microsoft.Windows.Controls; using System.ComponentModel; using System.Collections; using System.Collections.ObjectModel; namespace WRE.NGDAS.UILayer { /// <summary> /// Interaction logic for DataTableControl.xaml /// </summary> public partial class DataTableControl : UserControl { #region Constants private const int lineHeight = 25; #endregion #region Type Definitions private class TableChannelInfo { internal string ChannelName = string.Empty; internal int Column = 0; public override string ToString() { return ChannelName; } } internal class NotifyString : INotifyPropertyChanged { private string text = String.Empty; public event PropertyChangedEventHandler PropertyChanged; public string Text { get { return text; } set { text = value; NotifyPropertyChanged( "Text" ); } } public NotifyString(string newText) { text = newText; } protected void NotifyPropertyChanged( string propertyChanged ) { if ( PropertyChanged != null ) { PropertyChanged(this, new PropertyChangedEventArgs(propertyChanged)); } } } #endregion #region Private Data Members string[] channels = null; int numberFixed = 0; int numberOfRows = 0; ObservableCollection<ObservableCollection<NotifyString>> tableText = null; #endregion public DataTableControl( List<string> channelNames, List<string> nameToolTips, int numberFixedColumns, int numberRows ) { InitializeComponent(); numberFixed = numberFixedColumns; numberOfRows = numberRows; tableText = new ObservableCollection<ObservableCollection<NotifyString>>(); dataGrid.ItemsSource = tableText; channels = new string[channelNames.Count]; for (int channelIndex = 0; channelIndex < channelNames.Count; channelIndex++) { channels[channelIndex] = channelNames[channelIndex]; tableText.Add(new ObservableCollection<NotifyString>()); for (int i = 0; i < numberOfRows; i++) { tableText[channelIndex].Add( new NotifyString(String.Empty) ); } Binding textBinding = new Binding( ".[" + channelIndex + "]" ); textBinding.Mode = BindingMode.OneWay; textBinding.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged; textBinding.Source = tableText[channelIndex]; DataGridTextColumn newColumn = new DataGridTextColumn(); newColumn.Header = channelNames[channelIndex]; newColumn.DisplayIndex = channelIndex; newColumn.Binding = textBinding; if ( channelIndex < numberFixed ) { newColumn.CanUserReorder = false; } dataGrid.Columns.Add(newColumn); } //Height = lineHeight + numberOfRows * lineHeight; } internal void UpdateChannelRow( int rowNumber, List<string> channelValues, DisplayColors color ) { if ( rowNumber < numberOfRows ) { for (int column = 0; column < channelValues.Count; column++) { if ( column < channels.GetLength(0) ) { tableText[column][rowNumber].Text = channelValues[column]; } } } } } }

  • Beware Sneaky Reads with Unique Indexes

    - by Paul White NZ
    A few days ago, Sandra Mueller (twitter | blog) asked a question using twitter’s #sqlhelp hash tag: “Might SQL Server retrieve (out-of-row) LOB data from a table, even if the column isn’t referenced in the query?” Leaving aside trivial cases (like selecting a computed column that does reference the LOB data), one might be tempted to say that no, SQL Server does not read data you haven’t asked for.  In general, that’s quite correct; however there are cases where SQL Server might sneakily retrieve a LOB column… Example Table Here’s a T-SQL script to create that table and populate it with 1,000 rows: CREATE TABLE dbo.LOBtest ( pk INTEGER IDENTITY NOT NULL, some_value INTEGER NULL, lob_data VARCHAR(MAX) NULL, another_column CHAR(5) NULL, CONSTRAINT [PK dbo.LOBtest pk] PRIMARY KEY CLUSTERED (pk ASC) ); GO DECLARE @Data VARCHAR(MAX); SET @Data = REPLICATE(CONVERT(VARCHAR(MAX), 'x'), 65540);   WITH Numbers (n) AS ( SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0)) FROM master.sys.columns C1, master.sys.columns C2 ) INSERT LOBtest WITH (TABLOCKX) ( some_value, lob_data ) SELECT TOP (1000) N.n, @Data FROM Numbers N WHERE N.n <= 1000; Test 1: A Simple Update Let’s run a query to subtract one from every value in the some_value column: UPDATE dbo.LOBtest WITH (TABLOCKX) SET some_value = some_value - 1; As you might expect, modifying this integer column in 1,000 rows doesn’t take very long, or use many resources.  The STATITICS IO and TIME output shows a total of 9 logical reads, and 25ms elapsed time.  The query plan is also very simple: Looking at the Clustered Index Scan, we can see that SQL Server only retrieves the pk and some_value columns during the scan: The pk column is needed by the Clustered Index Update operator to uniquely identify the row that is being changed.  The some_value column is used by the Compute Scalar to calculate the new value.  (In case you are wondering what the Top operator is for, it is used to enforce SET ROWCOUNT). Test 2: Simple Update with an Index Now let’s create a nonclustered index keyed on the some_value column, with lob_data as an included column: CREATE NONCLUSTERED INDEX [IX dbo.LOBtest some_value (lob_data)] ON dbo.LOBtest (some_value) INCLUDE ( lob_data ) WITH ( FILLFACTOR = 100, MAXDOP = 1, SORT_IN_TEMPDB = ON ); This is not a useful index for our simple update query; imagine that someone else created it for a different purpose.  Let’s run our update query again: UPDATE dbo.LOBtest WITH (TABLOCKX) SET some_value = some_value - 1; We find that it now requires 4,014 logical reads and the elapsed query time has increased to around 100ms.  The extra logical reads (4 per row) are an expected consequence of maintaining the nonclustered index. The query plan is very similar to before (click to enlarge): The Clustered Index Update operator picks up the extra work of maintaining the nonclustered index. The new Compute Scalar operators detect whether the value in the some_value column has actually been changed by the update.  SQL Server may be able to skip maintaining the nonclustered index if the value hasn’t changed (see my previous post on non-updating updates for details).  Our simple query does change the value of some_data in every row, so this optimization doesn’t add any value in this specific case. The output list of columns from the Clustered Index Scan hasn’t changed from the one shown previously: SQL Server still just reads the pk and some_data columns.  Cool. Overall then, adding the nonclustered index hasn’t had any startling effects, and the LOB column data still isn’t being read from the table.  Let’s see what happens if we make the nonclustered index unique. Test 3: Simple Update with a Unique Index Here’s the script to create a new unique index, and drop the old one: CREATE UNIQUE NONCLUSTERED INDEX [UQ dbo.LOBtest some_value (lob_data)] ON dbo.LOBtest (some_value) INCLUDE ( lob_data ) WITH ( FILLFACTOR = 100, MAXDOP = 1, SORT_IN_TEMPDB = ON ); GO DROP INDEX [IX dbo.LOBtest some_value (lob_data)] ON dbo.LOBtest; Remember that SQL Server only enforces uniqueness on index keys (the some_data column).  The lob_data column is simply stored at the leaf-level of the non-clustered index.  With that in mind, we might expect this change to make very little difference.  Let’s see: UPDATE dbo.LOBtest WITH (TABLOCKX) SET some_value = some_value - 1; Whoa!  Now look at the elapsed time and logical reads: Scan count 1, logical reads 2016, physical reads 0, read-ahead reads 0, lob logical reads 36015, lob physical reads 0, lob read-ahead reads 15992.   CPU time = 172 ms, elapsed time = 16172 ms. Even with all the data and index pages in memory, the query took over 16 seconds to update just 1,000 rows, performing over 52,000 LOB logical reads (nearly 16,000 of those using read-ahead). Why on earth is SQL Server reading LOB data in a query that only updates a single integer column? The Query Plan The query plan for test 3 looks a bit more complex than before: In fact, the bottom level is exactly the same as we saw with the non-unique index.  The top level has heaps of new stuff though, which I’ll come to in a moment. You might be expecting to find that the Clustered Index Scan is now reading the lob_data column (for some reason).  After all, we need to explain where all the LOB logical reads are coming from.  Sadly, when we look at the properties of the Clustered Index Scan, we see exactly the same as before: SQL Server is still only reading the pk and some_value columns – so what’s doing the LOB reads? Updates that Sneakily Read Data We have to go as far as the Clustered Index Update operator before we see LOB data in the output list: [Expr1020] is a bit flag added by an earlier Compute Scalar.  It is set true if the some_value column has not been changed (part of the non-updating updates optimization I mentioned earlier). The Clustered Index Update operator adds two new columns: the lob_data column, and some_value_OLD.  The some_value_OLD column, as the name suggests, is the pre-update value of the some_value column.  At this point, the clustered index has already been updated with the new value, but we haven’t touched the nonclustered index yet. An interesting observation here is that the Clustered Index Update operator can read a column into the data flow as part of its update operation.  SQL Server could have read the LOB data as part of the initial Clustered Index Scan, but that would mean carrying the data through all the operations that occur prior to the Clustered Index Update.  The server knows it will have to go back to the clustered index row to update it, so it delays reading the LOB data until then.  Sneaky! Why the LOB Data Is Needed This is all very interesting (I hope), but why is SQL Server reading the LOB data?  For that matter, why does it need to pass the pre-update value of the some_value column out of the Clustered Index Update? The answer relates to the top row of the query plan for test 3.  I’ll reproduce it here for convenience: Notice that this is a wide (per-index) update plan.  SQL Server used a narrow (per-row) update plan in test 2, where the Clustered Index Update took care of maintaining the nonclustered index too.  I’ll talk more about this difference shortly. The Split/Sort/Collapse combination is an optimization, which aims to make per-index update plans more efficient.  It does this by breaking each update into a delete/insert pair, reordering the operations, removing any redundant operations, and finally applying the net effect of all the changes to the nonclustered index. Imagine we had a unique index which currently holds three rows with the values 1, 2, and 3.  If we run a query that adds 1 to each row value, we would end up with values 2, 3, and 4.  The net effect of all the changes is the same as if we simply deleted the value 1, and added a new value 4. By applying net changes, SQL Server can also avoid false unique-key violations.  If we tried to immediately update the value 1 to a 2, it would conflict with the existing value 2 (which would soon be updated to 3 of course) and the query would fail.  You might argue that SQL Server could avoid the uniqueness violation by starting with the highest value (3) and working down.  That’s fine, but it’s not possible to generalize this logic to work with every possible update query. SQL Server has to use a wide update plan if it sees any risk of false uniqueness violations.  It’s worth noting that the logic SQL Server uses to detect whether these violations are possible has definite limits.  As a result, you will often receive a wide update plan, even when you can see that no violations are possible. Another benefit of this optimization is that it includes a sort on the index key as part of its work.  Processing the index changes in index key order promotes sequential I/O against the nonclustered index. A side-effect of all this is that the net changes might include one or more inserts.  In order to insert a new row in the index, SQL Server obviously needs all the columns – the key column and the included LOB column.  This is the reason SQL Server reads the LOB data as part of the Clustered Index Update. In addition, the some_value_OLD column is required by the Split operator (it turns updates into delete/insert pairs).  In order to generate the correct index key delete operation, it needs the old key value. The irony is that in this case the Split/Sort/Collapse optimization is anything but.  Reading all that LOB data is extremely expensive, so it is sad that the current version of SQL Server has no way to avoid it. Finally, for completeness, I should mention that the Filter operator is there to filter out the non-updating updates. Beating the Set-Based Update with a Cursor One situation where SQL Server can see that false unique-key violations aren’t possible is where it can guarantee that only one row is being updated.  Armed with this knowledge, we can write a cursor (or the WHILE-loop equivalent) that updates one row at a time, and so avoids reading the LOB data: SET NOCOUNT ON; SET STATISTICS XML, IO, TIME OFF;   DECLARE @PK INTEGER, @StartTime DATETIME; SET @StartTime = GETUTCDATE();   DECLARE curUpdate CURSOR LOCAL FORWARD_ONLY KEYSET SCROLL_LOCKS FOR SELECT L.pk FROM LOBtest L ORDER BY L.pk ASC;   OPEN curUpdate;   WHILE (1 = 1) BEGIN FETCH NEXT FROM curUpdate INTO @PK;   IF @@FETCH_STATUS = -1 BREAK; IF @@FETCH_STATUS = -2 CONTINUE;   UPDATE dbo.LOBtest SET some_value = some_value - 1 WHERE CURRENT OF curUpdate; END;   CLOSE curUpdate; DEALLOCATE curUpdate;   SELECT DATEDIFF(MILLISECOND, @StartTime, GETUTCDATE()); That completes the update in 1280 milliseconds (remember test 3 took over 16 seconds!) I used the WHERE CURRENT OF syntax there and a KEYSET cursor, just for the fun of it.  One could just as well use a WHERE clause that specified the primary key value instead. Clustered Indexes A clustered index is the ultimate index with included columns: all non-key columns are included columns in a clustered index.  Let’s re-create the test table and data with an updatable primary key, and without any non-clustered indexes: IF OBJECT_ID(N'dbo.LOBtest', N'U') IS NOT NULL DROP TABLE dbo.LOBtest; GO CREATE TABLE dbo.LOBtest ( pk INTEGER NOT NULL, some_value INTEGER NULL, lob_data VARCHAR(MAX) NULL, another_column CHAR(5) NULL, CONSTRAINT [PK dbo.LOBtest pk] PRIMARY KEY CLUSTERED (pk ASC) ); GO DECLARE @Data VARCHAR(MAX); SET @Data = REPLICATE(CONVERT(VARCHAR(MAX), 'x'), 65540);   WITH Numbers (n) AS ( SELECT ROW_NUMBER() OVER (ORDER BY (SELECT 0)) FROM master.sys.columns C1, master.sys.columns C2 ) INSERT LOBtest WITH (TABLOCKX) ( pk, some_value, lob_data ) SELECT TOP (1000) N.n, N.n, @Data FROM Numbers N WHERE N.n <= 1000; Now here’s a query to modify the cluster keys: UPDATE dbo.LOBtest SET pk = pk + 1; The query plan is: As you can see, the Split/Sort/Collapse optimization is present, and we also gain an Eager Table Spool, for Halloween protection.  In addition, SQL Server now has no choice but to read the LOB data in the Clustered Index Scan: The performance is not great, as you might expect (even though there is no non-clustered index to maintain): Table 'LOBtest'. Scan count 1, logical reads 2011, physical reads 0, read-ahead reads 0, lob logical reads 36015, lob physical reads 0, lob read-ahead reads 15992.   Table 'Worktable'. Scan count 1, logical reads 2040, physical reads 0, read-ahead reads 0, lob logical reads 34000, lob physical reads 0, lob read-ahead reads 8000.   SQL Server Execution Times: CPU time = 483 ms, elapsed time = 17884 ms. Notice how the LOB data is read twice: once from the Clustered Index Scan, and again from the work table in tempdb used by the Eager Spool. If you try the same test with a non-unique clustered index (rather than a primary key), you’ll get a much more efficient plan that just passes the cluster key (including uniqueifier) around (no LOB data or other non-key columns): A unique non-clustered index (on a heap) works well too: Both those queries complete in a few tens of milliseconds, with no LOB reads, and just a few thousand logical reads.  (In fact the heap is rather more efficient). There are lots more fun combinations to try that I don’t have space for here. Final Thoughts The behaviour shown in this post is not limited to LOB data by any means.  If the conditions are met, any unique index that has included columns can produce similar behaviour – something to bear in mind when adding large INCLUDE columns to achieve covering queries, perhaps.

  • Cannot connect to one of my WCF services, not even with telnet

    - by Ecyrb
    I have six wcf services that I'm hosting in a windows service. Everything works great on my machine (Windows 7) but when I try it in production (Windows Server 2003) I cannot connect to one of my six services, ReportsService. I figured I must have a typo, but everything looks right. I've even rewritten that section of the config file just to be sure. I've turned on WCF tracing, but it never shows the call to my service; nothing helpful in there. I tried connecting to the port (9005) with telnet, but it failed. I can connect to all other services (ports 9001-4 and 9006) just fine. I thought that maybe there was a problem with port 9005, so I changed it to 9007 and still couldn't connect. I had one of my working services host on 9005 and it actually worked fine. So I'm pretty sure there's nothing wrong with the port or any firewall settings. Whatever port I tell ReportsService to use fails. Now I'm out of ideas. It seems like it's not hosting that one service, but I cannot get any information about why or what's wrong. Any ideas on what I could try to get that information? Or what might be wrong? The unhandled System.ServiceModel.EndpointNotFoundException I get when running my client is: Could not connect to net.tcp://localhost:9005/ReportsService. The connection attempt lasted for a time span of 00:00:01.0937430. TCP error code 10061: No connection could be made because the target machine actively refused it 172.0.0.1:9005. . My host's config file contains: <!-- Snipped other services to simplify for you. --> <endpoint binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IReportsService" /> <endpoint binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IUpdateData" /> IReportService is the one I'm having trouble with. I get a proxy to IReportsService with the following code, where Server is the name of the hosting machine: return new ChannelFactory<IReportsService>("").CreateChannel(new EndpointAddress(string.Format("net.tcp://{0}:9005/ReportsService", Server))); My client config file contains: <system.serviceModel> <bindings> <netTcpBinding> <binding name="customTcpBinding" maxReceivedMessageSize="2147483647"> <readerQuotas maxNameTableCharCount="2147483647" maxStringContentLength="2147483647"/> <security mode="None"/> </binding> </netTcpBinding> </bindings> <behaviors> <serviceBehaviors> <behavior name="ServiceBehavior"> <serviceMetadata httpGetEnabled="True"/> <serviceDebug includeExceptionDetailInFaults="True" /> <serviceThrottling maxConcurrentCalls="30" maxConcurrentInstances="30" maxConcurrentSessions="1000" /> </behavior> </serviceBehaviors> </behaviors> <services> <!-- Snipped other services to simplify for you. --> <service behaviorConfiguration="ServiceBehavior" name="WcfService.ReportsService"> <endpoint address="ReportsService" binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IReportsService" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:9005" /> </baseAddresses> </host> </service> <service behaviorConfiguration="ServiceBehavior" name="WcfService.UpdateData"> <endpoint address="UpdateData" binding="netTcpBinding" bindingConfiguration="customTcpBinding" contract="ServiceContracts.IUpdateData" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> <host> <baseAddresses> <add baseAddress="net.tcp://localhost:9006" /> </baseAddresses> </host> </service> </services> </system.serviceModel> I've tried to keep things simple with the code snippets above, but if you would like to see more just ask and I'd be happy to provide anything that'll help.

  • Facebook Connect login button not rendering

    - by tloflin
    I'm trying to implement a Facebook Connect Single Sign-on site. I originally just had a Connect button (<fb:login-button>), which the user had to click every time they wanted to sign in. I now have the auto login and logout features working. That is, my site will detect a logged-in Facebook account and automatically authenticate them if it can find a match to one of my site's user accounts, and automatically deauthenticate if the Facebook session is lost. I also have a manual logout button that will log the user out of both my site and Facebook. All of those are working correctly, but now my original Connect button is intermittently not being rendered correctly. It just shows up as the plain XHTML (ie., it looks like plain text--not a button--and is unclickable), and no XFBML is applied. Here is the basic code: On every page: <body> {...} <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> <script type="text/javascript> FB.init('APIKey', '/xd_receiver.htm'); var isAuth; // isAuth determines if the user is authenticated on my site // it should be true on the logout page, false on the login page FB.ensureInit(function(){ var session = FB.Facebook.apiClient.get_session(); if (session && !isAuth) { PageMethods.FacebookLogin(session.uid, session.session_key, FBLogin, FBLoginFail); // This is an AJAX call that authenticates the user on my site. } else if(!session && isFBAuth) { PageMethods.FacebookLogout(FBLogout, FBLogoutFail); // This is an AJAX call that deauthenticates the user on my site. } // the callback functions do nothing at the moment }); </script> {...} </body> On the login page: (this page is not visible to logged in users) <body> {...} <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> <script type="text/javascript> FB.init('APIKey', '/xd_receiver.htm'); {...} // auto-auth code as on every page </script> <!-- This is the button that fails to render --> <fb:login-button v="2" onlogin="UserSignedIntoFB();" size="large" autologoutlink="true"><fb:intl>Login With Your Facebook Account</fb:intl></fb:login-button> <script type="text/javascript"> function UserSignedIntoFB() { {...} // posts back to the server which authenticates the user on my site & redirects } </script> {...} </body> On the logout page: (this page is not visible to logged out users) <body> {...} <script src="http://static.ak.connect.facebook.com/js/api_lib/v0.4/FeatureLoader.js.php" type="text/javascript"></script> <script type="text/javascript> FB.init('APIKey', '/xd_receiver.htm'); {...} // auto-auth code as on every page </script> <script type="text/javascript"> function FBLoggedOut() { {...} // posts back to the server which deauthenticates the user on my site & redirects to login } function Logout() { if (FB.Facebook.apiClient.get_session()) { FB.Connect.logout(FBLoggedOut); // logs out of Facebook if it's a Facebook account return false; } else { return true; // posts back if it's a non-Facebook account & redirects to login } } </script> <a onclick="return Logout();" href="postback_url">Sign Out</a> {...} </body> Some things I've already looked at: The automatic login and logout are working great. I can log in and out of Facebook on another tab and my site will notice the session changes and update accordingly. The logout seems to be working fine: when clicked, it deauthenticates the user and logs them out of Facebook, as intended. The issue seems to usually happen after a Facebook user is logged out, but it happens somewhat intermittently; it might happen before they ever login, and it goes away after a few minutes/refreshes. Some cookies are left over after the login/logout process, but deleting them does not fix the issue. Restarting the browser does not fix the issue. The user is definitely logged out of Facebook and my site when the problem occurs. I've checked for Facebook sessions and site authentication. All external script calls are being served up correctly. I have a suspicion that there's something else I need to be doing upon logout (like clearing session or cookies), but according to everything I've read about Facebook Connect, all I need to do is call the logout function (and deauthenticate on my server-side). I'm really at a loss; does anybody have any ideas what could be wrong?

  • Auto blocking attacking IP address

    - by dong
    This is to share my PowerShell code online. I original asked this question on MSDN forum (or TechNet?) here: http://social.technet.microsoft.com/Forums/en-US/winserversecurity/thread/f950686e-e3f8-4cf2-b8ec-2685c1ed7a77 In short, this is trying to find attacking IP address then add it into Firewall block rule. So I suppose: 1, You are running a Windows Server 2008 facing the Internet. 2, You need to have some port open for service, e.g. TCP 21 for FTP; TCP 3389 for Remote Desktop. You can see in my code I’m only dealing with these two since that’s what I opened. You can add further port number if you like, but the way to process might be different with these two. 3, I strongly suggest you use STRONG password and follow all security best practices, this ps1 code is NOT for adding security to your server, but reduce the nuisance from brute force attack, and make sys admin’s life easier: i.e. your FTP log won’t hold megabytes of nonsense, your Windows system log will not roll back and only can tell you what happened last month. 4, You are comfortable with setting up Windows Firewall rules, in my code, my rule has a name of “MY BLACKLIST”, you need to setup a similar one, and set it to BLOCK everything. 5, My rule is dangerous because it has the risk to block myself out as well. I do have a backup plan i.e. the DELL DRAC5 so that if that happens, I still can remote console to my server and reset the firewall. 6, By no means the code is perfect, the coding style, the use of PowerShell skills, the hard coded part, all can be improved, it’s just that it’s good enough for me already.

Please replace as well. 3, The threshold for 3389 attack is 20, you don’t want to block yourself just because you typed your password wrong 3 times, you can change this threshold by your own reasoning. 4, FTP is checking the log for attack only to the last 5 mins, you can change that as well. 5, I suppose the server is serving FTP on both IP address and their LOG path are C:\inetpub\logs\LogFiles\FPTSVC2 and C:\inetpub\logs\LogFiles\FPTSVC3. Change accordingly. 6, FTP checking code is only asking for the last 200 lines of log, and the threshold is 10, change as you wish. 7, the code runs in a loop, you can set the loop time at the last line. To run this code, copy and paste to your editor, finish all the editing, get it to your server, and open an CMD window, then type powershell.exe –file your_powershell_file_name.ps1, it will start running, you can Ctrl-C to break it. This is what you see when it’s running: This is when it detected attack and adding the firewall rule: Regarding the design of the code: 1, There are many ways you can detect the attack, but to add an IP into a block rule is no small thing, you need to think hard before doing it, reason for that may include: You don’t want block yourself; and not blocking your customer/user, i.e. the good guy. 2, Thus for each service/port, I double check. For 3389, first it needs to show in netstat.exe, then the Event log; for FTP, first check the Event log, then the FTP log files. 3, At three places I need to make sure I’m not adding myself into the block rule. –ne with single IP, –like with subnet.   Now the final bit: 1, The code will stop working after a while (depends on how busy you are attacked, could be weeks, months, or days?!) It will throw Red error message in CMD, don’t Panic, it does no harm, but it also no longer blocking new attack. THE REASON is not confirmed with MS people: the COM object to manage firewall, you can only give it a list of IP addresses to the length of around 32KB I think, once it reaches the limit, you get the error message. 2, This is in fact my second solution to use the COM object, the first solution is still in the comment block for your reference, which is using netsh, that fails because being run from CMD, you can only throw it a list of IP to 8KB. 3, I haven’t worked the workaround yet, some ideas include: wrap that RemoteAddresses setting line with error checking and once it reaches the limit, use the newly detected IP to be the list, not appending to it. This basically reset your block rule to ground zero and lose the previous bad IPs. This does no harm as it sounds, because given a certain period has passed, any these bad IPs still not repent and continue the attack to you, it only got 30 seconds or 20 guesses of your password before you block it again. And there is the benefit that the bad IP may turn back to the good hands again, and you are not blocking a potential customer or your CEO’s home pc because once upon a time, it’s a zombie. Thus the ZEN of blocking: never block any IP for too long. 4, But if you insist to block the ugly forever, my other ideas include: You call MS support, ask them how can we set an arbitrary length of IP addresses in a rule; at least from my experiences at the Forum, they don’t know and they don’t care, because they think the dynamic blocking should be done by some expensive hardware. Or, from programming perspective, you can create a new rule once the old is full, then you’ll have MY BLACKLIST1, MY  BLACKLIST2, MY BLACKLIST3, … etc. Once in a while you can compile them together and start a business to sell your blacklist on the market! Enjoy the code! p.s. (PowerShell is REALLY REALLY GREAT!)

  • Flex actionscript extending DateChooser, events in calendar

    - by Nemi
    ExtendedDateChooser class is great solution for simple event calendar used in my flex project. You can find it if google for "Adding-Calendar-Event-Entries-to-the-Flex-DateChooser-Component" with a link of updated solution in comments of the post. I posted files below. Problem in that calendar is text events are missing when month is changed. Is there updateCompleted event in Actionscript just like in dateChooser flex component? Like in: <mx:DateChooser id="dc" updateCompleted="goThroughDateChooserCalendarLayoutAndSetEventsInCalendarAgain()"</mx> When scroll event is added, which is available in Actionscript, it gets dispatched but after updateDisplayList() is fired, so didn't manage to answer, why are calendar events erased? Any suggestions, what to add in code, maybe override some function?

  • Dynamic XAP loading in Task-It - Part 1

    Download Source Code NOTE 1: The source code provided is running against the RC versions of Silverlight 4 and VisualStudio 2010, so you will need to update to those bits to run it. NOTE 2: After downloading the source, be sure to set the .Web project as the StartUp Project, and Default.aspx as the Start Page In my MEF into post, MEF to the rescue in Task-It, I outlined a couple of issues I was facing and explained why I chose MEF (the Managed Extensibility Framework) to solve these issues. Other posts to check out There are a few other resources out there around dynamic XAP loading that you may want to review (by the way, Glenn Block is the main dude when it comes to MEF): Glenn Blocks 3-part series on a dynamically loaded dashboard Glenn and John Papas Silverlight TV video on dynamic xap loading These provide some great info, but didnt exactly cover the scenario I wanted to achieve in Task-Itand that is dynamically loading each of the apps pages the first time the user enters a page. The code In the code I provided for download above, I created a simple solution that shows the technique I used for dynamic XAP loading in Task-It, but without all of the other code that surrounds it. Taking all that other stuff away should make it easier to grasp. Having said that, there is still a fair amount of code involved. I am always looking for ways to make things simpler, and to achieve the desired result with as little code as possible, so if I find a better/simpler way I will blog about it, but for now this technique works for me. When I created this solution I started by creating a new Silverlight Navigation Application called DynamicXAP Loading. I then added the following line to my UriMappings in MainPage.xaml: <uriMapper:UriMapping Uri="/{assemblyName};component/{path}" MappedUri="/{assemblyName};component/{path}"/> In the section of MainPage.xaml that produces the page links in the upper right, I kept the Home link, but added a couple of new ones (page1 and page 2). These are the pages that will be dynamically (lazy) loaded: <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}">      <HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/Home" TargetName="ContentFrame" Content="home"/>      <Rectangle Style="{StaticResource DividerStyle}"/>      <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 1" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage1}"/>      <Rectangle Style="{StaticResource DividerStyle}"/>      <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 2" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage2}"/>  </StackPanel> In App.xaml.cs I added a bit of MEF code. In Application_Startup I call a method called InitializeContainer, which creates a PackageCatalog (a MEF thing), then I create a CompositionContainer and pass it to the CompositionHost.Initialize method. This is boiler-plate MEF stuff that allows you to do 'composition' and import 'packages'. You're welcome to do a bit more MEF research on what is happening here if you'd like, but for the purpose of this example you can just trust that it works. :-) private void Application_Startup(object sender, StartupEventArgs e) {     InitializeContainer();     this.RootVisual = new MainPage(); }   private static void InitializeContainer() {     var catalog = new PackageCatalog();     catalog.AddPackage(Package.Current);     var container = new CompositionContainer(catalog);     container.ComposeExportedValue(catalog);     CompositionHost.Initialize(container); } Infrastructure In the sample code you'll notice that there is a project in the solution called DynamicXAPLoading.Infrastructure. This is simply a Silverlight Class Library project that I created just to move stuff I considered application 'infrastructure' code into a separate place, rather than cluttering the main Silverlight project (DynamicXapLoading). I did this same thing in Task-It, as the amount of this type of code was starting to clutter up the Silverlight project, and it just seemed to make sense to move things like Enums, Constants and the like off to a separate place. In the DynamicXapLoading.Infrastructure project you'll see 3 classes: Enums - There is only one enum in here called ModuleEnum. We'll use these later. PageMetadata - We will use this class later to add metadata to a new dynamically loaded project. ViewModelBase - This is simply a base class for view models that we will use in this, as well as future samples. As mentioned in my MVVM post, I will be using the MVVM pattern throughout my code for reasons detailed in the post. By the way, the ViewModelExtension class in there allows me to do strongly-typed property changed notification, so rather than OnPropertyChanged("MyProperty"), I can do this.OnPropertyChanged(p => p.MyProperty). It's just a less error-prown approach, because if you don't spell "MyProperty" correctly using the first method, nothing will break, it just won't work. Adding a new page We currently have a couple of pages that are being dynamically (lazy) loaded, but now let's add a third page. 1. First, create a new Silverlight Application project: In this example I call it Page3. In the future you may prefer to use a different name, like DynamicXAPLoading.Page3, or even DynamicXAPLoading.Modules.Page3. It can be whatever you want. In my Task-It application I used the latter approach (with 'Modules' in the name). I do think of these application as 'modules', but Prism uses the same term, so some folks may not like that. Use whichever naming convention you feel is appropriate, but for now Page3 will do. When you change the name to Page3 and click OK, you will be presented with the Add New Project dialog: It is important that you leave the 'Host the Silverlight application in a new or existing Web site in the solution' checked, and the .Web project will be selected in the dropdown below. This will create the .xap file for this project under ClientBin in the .Web project, which is where we want it. 2. Uncheck the 'Add a test page that references the application' checkbox, and leave everything else as is. 3. Once the project is created, you can delete App.xaml and MainPage.xaml. 4. You will need to add references your new project to the following: DynamicXAPLoading.Infrastructure.dll (this is a Project reference) DynamicNavigation.dll (this is in the Libs directory under the DynamicXAPLoading project) System.ComponentModel.Composition.dll System.ComponentModel.Composition.Initialization.dll System.Windows.Controls.Navigation.dll If you have installed the latest RC bits you will find the last 3 dll's under the .NET tab in the Add Referenced dialog. They live in the following location, or if you are on a 64-bit machine like me, it will be Program Files (x86).       C:\Program Files\Microsoft SDKs\Silverlight\v4.0\Libraries\Client Now let's create some UI for our new project. 5. First, create a new Silverlight User Control called Page3.dyn.xaml 6. Paste the following code into the xaml: <dyn:DynamicPageShim xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation"     xmlns:my="clr-namespace:Page3;assembly=Page3">     <my:Page3Host /> </dyn:DynamicPageShim> This is just a 'shim', part of David Poll's technique for dynamic loading. 7. Expand the icon next to Page3.dyn.xaml and delete the code-behind file (Page3.dyn.xaml.cs). 8. Next we will create a control that will 'host' our page. Create another Silverlight User Control called Page3Host.xaml and paste in the following XAML: <dyn:DynamicPage x:Class="Page3.Page3Host"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation"     xmlns:Views="clr-namespace:Page3.Views"      mc:Ignorable="d"     d:DesignHeight="300" d:DesignWidth="400"     Title="Page 3">       <Views:Page3/>   </dyn:DynamicPage> 9. Now paste the following code into the code-behind for this control: using DynamicXAPLoading.Infrastructure;   namespace Page3 {     [PageMetadata(NavigateUri = "/Page3;component/Page3.dyn.xaml", Module = Enums.Page3)]     public partial class Page3Host     {         public Page3Host()         {             InitializeComponent();         }     } } Notice that we are now using that PageMetadata custom attribute class that we created in the Infrastructure project, and setting its two properties. NavigateUri - This tells it that the assembly is called Page3 (with a slash beforehand), and the page we want to load is Page3.dyn.xaml...our 'shim'. That line we added to the UriMapper in MainPage.xaml will use this information to load the page. Module - This goes back to that ModuleEnum class in our Infrastructure project. However, setting the Module to ModuleEnum.Page3 will cause a compilation error, so... 10. Go back to that Enums.cs under the Infrastructure project and add a 3rd entry for Page3: public enum ModuleEnum {     Page1,     Page2,     Page3 } 11. Now right-click on the Page3 project and add a folder called Views. 12. Right-click on the Views folder and create a new Silverlight User Control called Page3.xaml. We won't bother creating a view model for this User Control as I did in the Page 1 and Page 2 projects, just for the sake of simplicity. Feel free to add one if you'd like though, and copy the code from one of those other projects. Right now those view models aren't really doing anything anyway...though they will in my next post. :-) 13. Now let's replace the xaml for Page3.xaml with the following: <dyn:DynamicPage x:Class="Page3.Views.Page3"     xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"     xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"     xmlns:d="http://schemas.microsoft.com/expression/blend/2008"     xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"     xmlns:dyn="clr-namespace:DynamicNavigation;assembly=DynamicNavigation"     mc:Ignorable="d"     d:DesignHeight="300" d:DesignWidth="400"     Style="{StaticResource PageStyle}">       <Grid x:Name="LayoutRoot">         <ScrollViewer x:Name="PageScrollViewer" Style="{StaticResource PageScrollViewerStyle}">             <StackPanel x:Name="ContentStackPanel">                 <TextBlock x:Name="HeaderText" Style="{StaticResource HeaderTextStyle}" Text="Page 3"/>                 <TextBlock x:Name="ContentText" Style="{StaticResource ContentTextStyle}" Text="Page 3 content"/>             </StackPanel>         </ScrollViewer>     </Grid>   </dyn:DynamicPage> 14. And in the code-behind remove the inheritance from UserControl, so it should look like this: namespace Page3.Views {     public partial class Page3     {         public Page3()         {             InitializeComponent();         }     } } One thing you may have noticed is that the base class for the last two User Controls we created is DynamicPage. Once again, we are using the infrastructure that David Poll created. 15. OK, a few last things. We need a link on our main page so that we can access our new page. In MainPage.xaml let's update our links to look like this: <StackPanel x:Name="LinksStackPanel" Style="{StaticResource LinksStackPanelStyle}">     <HyperlinkButton Style="{StaticResource LinkStyle}" NavigateUri="/Home" TargetName="ContentFrame" Content="home"/>     <Rectangle Style="{StaticResource DividerStyle}"/>     <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 1" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage1}"/>     <Rectangle Style="{StaticResource DividerStyle}"/>     <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 2" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage2}"/>     <Rectangle Style="{StaticResource DividerStyle}"/>     <HyperlinkButton Style="{StaticResource LinkStyle}" Content="page 3" Command="{Binding NavigateCommand}" CommandParameter="{Binding ModulePage3}"/> </StackPanel> 16. Next, we need to add the following at the bottom of MainPageViewModel in the ViewModels directory of our DynamicXAPLoading project: public ModuleEnum ModulePage3 {     get { return ModuleEnum.Page3; } } 17. And at last, we need to add a case for our new page to the switch statement in MainPageViewModel: switch (module) {     case ModuleEnum.Page1:         DownloadPackage("Page1.xap");         break;     case ModuleEnum.Page2:         DownloadPackage("Page2.xap");         break;     case ModuleEnum.Page3:         DownloadPackage("Page3.xap");         break;     default:         break; } Now fire up the application and click the page 1, page 2 and page 3 links. What you'll notice is that there is a 2-second delay the first time you hit each page. That is because I added the following line to the Navigate method in MainPageViewModel: Thread.Sleep(2000); // Simulate a 2 second initial loading delay The reason I put this in there is that I wanted to simulate a delay the first time the page loads (as the .xap is being downloaded from the server). You'll notice that after the first hit to the page though that there is no delay...that's because the .xap has already been downloaded. Feel free to comment out this 2-second delay, or remove it if you'd like. I just wanted to show how subsequent hits to the page would be quicker than the initial one. By the way, you may want to display some sort of BusyIndicator while the .xap is loading. I have that in my Task-It appplication, but for the sake of simplicity I did not include it here. In the future I'll blog about how I show and hide the BusyIndicator using events (I'm currently using the eventing framework in Prism for that, but may move to the one in the MVVM Light Toolkit some time soon). Whew, that felt like a lot of steps, but it does work quite nicely. As I mentioned earlier, I'll try to find ways to simplify the code (I'd like to get away from having things like hard-coded .xap file names) and will blog about it in the future if I find a better way. In my next post, I'll talk more about what is actually happening with the code that makes this all work.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • Synchronize Data between a Silverlight ListBox and a User Control

    - by psheriff
    One of the great things about XAML is the powerful data-binding capabilities. If you load up a list box with a collection of objects, you can display detail data about each object without writing any C# or VB.NET code. Take a look at Figure 1 that shows a collection of Product objects in a list box. When you click on a list box you bind the current Product object selected in the list box to a set of controls in a user control with just a very simple Binding statement in XAML.  Figure 1: Synchronizing a ListBox to a User Control is easy with Data Binding Product and Products Classes To illustrate this data binding feature I am going to just create some local data instead of using a WCF service. The code below shows a Product class that has three properties, namely, ProductId, ProductName and Price. This class also has a constructor that takes 3 parameters and allows us to set the 3 properties in an instance of our Product class. C#public class Product{  public Product(int productId, string productName, decimal price)  {    ProductId = productId;    ProductName = productName;    Price = price;  }   public int ProductId { get; set; }  public string ProductName { get; set; }  public decimal Price { get; set; }} VBPublic Class Product  Public Sub New(ByVal _productId As Integer, _                 ByVal _productName As String, _                 ByVal _price As Decimal)    ProductId = _productId    ProductName = _productName    Price = _price  End Sub   Private mProductId As Integer  Private mProductName As String  Private mPrice As Decimal   Public Property ProductId() As Integer    Get      Return mProductId    End Get    Set(ByVal value As Integer)      mProductId = value    End Set  End Property   Public Property ProductName() As String    Get      Return mProductName    End Get    Set(ByVal value As String)      mProductName = value    End Set  End Property   Public Property Price() As Decimal    Get      Return mPrice    End Get    Set(ByVal value As Decimal)      mPrice = value    End Set  End PropertyEnd Class To fill up a list box you need a collection class of Product objects. The code below creates a generic collection class of Product objects. In the constructor of the Products class I have hard-coded five product objects and added them to the collection. In a real-world application you would get your data through a call to service to fill the list box, but for simplicity and just to illustrate the data binding, I am going to just hard code the data. C#public class Products : List<Product>{  public Products()  {    this.Add(new Product(1, "Microsoft VS.NET 2008", 1000));    this.Add(new Product(2, "Microsoft VS.NET 2010", 1000));    this.Add(new Product(3, "Microsoft Silverlight 4", 1000));    this.Add(new Product(4, "Fundamentals of N-Tier eBook", 20));    this.Add(new Product(5, "ASP.NET Security eBook", 20));  }} VBPublic Class Products  Inherits List(Of Product)   Public Sub New()    Me.Add(New Product(1, "Microsoft VS.NET 2008", 1000))    Me.Add(New Product(2, "Microsoft VS.NET 2010", 1000))    Me.Add(New Product(3, "Microsoft Silverlight 4", 1000))    Me.Add(New Product(4, "Fundamentals of N-Tier eBook", 20))    Me.Add(New Product(5, "ASP.NET Security eBook", 20))  End SubEnd Class The Product Detail User Control Below is a user control (named ucProduct) that is used to display the product detail information seen in the bottom portion of Figure 1. This is very basic XAML that just creates a text block and a text box control for each of the three properties in the Product class. Notice the {Binding Path=[PropertyName]} on each of the text box controls. This means that if the DataContext property of this user control is set to an instance of a Product class, then the data in the properties of that Product object will be displayed in each of the text boxes. <UserControl x:Class="SL_SyncListBoxAndUserControl_CS.ucProduct"  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  HorizontalAlignment="Left"  VerticalAlignment="Top">  <Grid Margin="4">    <Grid.RowDefinitions>      <RowDefinition Height="Auto" />      <RowDefinition Height="Auto" />      <RowDefinition Height="Auto" />    </Grid.RowDefinitions>    <Grid.ColumnDefinitions>      <ColumnDefinition MinWidth="120" />      <ColumnDefinition />    </Grid.ColumnDefinitions>    <TextBlock Grid.Row="0"               Grid.Column="0"               Text="Product Id" />    <TextBox Grid.Row="0"             Grid.Column="1"             Text="{Binding Path=ProductId}" />    <TextBlock Grid.Row="1"               Grid.Column="0"               Text="Product Name" />    <TextBox Grid.Row="1"             Grid.Column="1"             Text="{Binding Path=ProductName}" />    <TextBlock Grid.Row="2"               Grid.Column="0"               Text="Price" />    <TextBox Grid.Row="2"             Grid.Column="1"             Text="{Binding Path=Price}" />  </Grid></UserControl> Synchronize ListBox with User Control You are now ready to fill the list box with the collection class of Product objects and then bind the SelectedItem of the list box to the Product detail user control. The XAML below is the complete code for Figure 1. <UserControl x:Class="SL_SyncListBoxAndUserControl_CS.MainPage"  xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"  xmlns:src="clr-namespace:SL_SyncListBoxAndUserControl_CS"  VerticalAlignment="Top"  HorizontalAlignment="Left">  <UserControl.Resources>    <src:Products x:Key="productCollection" />  </UserControl.Resources>  <Grid x:Name="LayoutRoot"        Margin="4"        Background="White">    <Grid.RowDefinitions>      <RowDefinition Height="Auto" />      <RowDefinition Height="*" />    </Grid.RowDefinitions>    <ListBox x:Name="lstData"             Grid.Row="0"             BorderBrush="Black"             BorderThickness="1"             ItemsSource="{Binding                   Source={StaticResource productCollection}}"             DisplayMemberPath="ProductName" />    <src:ucProduct x:Name="prodDetail"                   Grid.Row="1"                   DataContext="{Binding ElementName=lstData,                                          Path=SelectedItem}" />  </Grid></UserControl> The first step to making this happen is to reference the Silverlight project (SL_SyncListBoxAndUserControl_CS) where the Product and Products classes are located. I added this namespace and assigned it a namespace prefix of “src” as shown in the line below: xmlns:src="clr-namespace:SL_SyncListBoxAndUserControl_CS" Next, to use the data from an instance of the Products collection, you create a UserControl.Resources section in the XAML and add a tag that creates an instance of the Products class and assigns it a key of “productCollection”.   <UserControl.Resources>    <src:Products x:Key="productCollection" />  </UserControl.Resources> Next, you bind the list box to this productCollection object using the ItemsSource property. You bind the ItemsSource of the list box to the static resource named productCollection. You can then set the DisplayMemberPath attribute of the list box to any property of the Product class that you want. In the XAML below I used the ProductName property. <ListBox x:Name="lstData"         ItemsSource="{Binding             Source={StaticResource productCollection}}"         DisplayMemberPath="ProductName" /> You now need to create an instance of the ucProduct user contol below the list box. You do this by once again referencing the “src” namespace and typing in the name of the user control. You then set the DataContext property on this user control to a binding. The binding uses the ElementName attribute to bind to the list box name, in this case “lstData”. The Path of the data is SelectedItem. These two attributes together tell Silverlight to bind the DataContext to the selected item of the list box. That selected item is a Product object. So, once this is bound, the bindings on each text box in the user control are updated and display the current product information. <src:ucProduct x:Name="prodDetail"               DataContext="{Binding ElementName=lstData,                                      Path=SelectedItem}" /> Summary Once you understand the basics of data binding in XAML, you eliminate a lot code that is otherwise needed to move data into controls and out of controls back into an object. Connecting two controls together is easy by just binding using the ElementName and Path properties of the Binding markup extension. Another good tip out of this blog is use user controls and set the DataContext of the user control to have all of the data on the user control update through the bindings.

  • C#/.NET Fundamentals: Choosing the Right Collection Class

    The .NET Base Class Library (BCL) has a wide array of collection classes at your disposal which make it easy to manage collections of objects. While it's great to have so many classes available, it can be daunting to choose the right collection to use for any given situation. As hard as it may be, choosing the right collection can be absolutely key to the performance and maintainability of your application! This post will look at breaking down any confusion between each collection and the situations in which they excel. We will be spending most of our time looking at the System.Collections.Generic namespace, which is the recommended set of collections. The Generic Collections: System.Collections.Generic namespace The generic collections were introduced in .NET 2.0 in the System.Collections.Generic namespace. This is the main body of collections you should tend to focus on first, as they will tend to suit 99% of your needs right up front. It is important to note that the generic collections are unsynchronized. This decision was made for performance reasons because depending on how you are using the collections its completely possible that synchronization may not be required or may be needed on a higher level than simple method-level synchronization. Furthermore, concurrent read access (all writes done at beginning and never again) is always safe, but for concurrent mixed access you should either synchronize the collection or use one of the concurrent collections. So let's look at each of the collections in turn and its various pros and cons, at the end we'll summarize with a table to help make it easier to compare and contrast the different collections. The Associative Collection Classes Associative collections store a value in the collection by providing a key that is used to add/remove/lookup the item. Hence, the container associates the value with the key. These collections are most useful when you need to lookup/manipulate a collection using a key value. For example, if you wanted to look up an order in a collection of orders by an order id, you might have an associative collection where they key is the order id and the value is the order. The Dictionary<TKey,TVale> is probably the most used associative container class. The Dictionary<TKey,TValue> is the fastest class for associative lookups/inserts/deletes because it uses a hash table under the covers. Because the keys are hashed, the key type should correctly implement GetHashCode() and Equals() appropriately or you should provide an external IEqualityComparer to the dictionary on construction. The insert/delete/lookup time of items in the dictionary is amortized constant time - O(1) - which means no matter how big the dictionary gets, the time it takes to find something remains relatively constant. This is highly desirable for high-speed lookups. The only downside is that the dictionary, by nature of using a hash table, is unordered, so you cannot easily traverse the items in a Dictionary in order. The SortedDictionary<TKey,TValue> is similar to the Dictionary<TKey,TValue> in usage but very different in implementation. The SortedDictionary<TKey,TValye> uses a binary tree under the covers to maintain the items in order by the key. As a consequence of sorting, the type used for the key must correctly implement IComparable<TKey> so that the keys can be correctly sorted. The sorted dictionary trades a little bit of lookup time for the ability to maintain the items in order, thus insert/delete/lookup times in a sorted dictionary are logarithmic - O(log n). Generally speaking, with logarithmic time, you can double the size of the collection and it only has to perform one extra comparison to find the item. Use the SortedDictionary<TKey,TValue> when you want fast lookups but also want to be able to maintain the collection in order by the key. The SortedList<TKey,TValue> is the other ordered associative container class in the generic containers. Once again SortedList<TKey,TValue>, like SortedDictionary<TKey,TValue>, uses a key to sort key-value pairs. Unlike SortedDictionary, however, items in a SortedList are stored as an ordered array of items. This means that insertions and deletions are linear - O(n) - because deleting or adding an item may involve shifting all items up or down in the list. Lookup time, however is O(log n) because the SortedList can use a binary search to find any item in the list by its key. So why would you ever want to do this? Well, the answer is that if you are going to load the SortedList up-front, the insertions will be slower, but because array indexing is faster than following object links, lookups are marginally faster than a SortedDictionary. Once again I'd use this in situations where you want fast lookups and want to maintain the collection in order by the key, and where insertions and deletions are rare. The Non-Associative Containers The other container classes are non-associative. They don't use keys to manipulate the collection but rely on the object itself being stored or some other means (such as index) to manipulate the collection. The List<T> is a basic contiguous storage container. Some people may call this a vector or dynamic array. Essentially it is an array of items that grow once its current capacity is exceeded. Because the items are stored contiguously as an array, you can access items in the List<T> by index very quickly. However inserting and removing in the beginning or middle of the List<T> are very costly because you must shift all the items up or down as you delete or insert respectively. However, adding and removing at the end of a List<T> is an amortized constant operation - O(1). Typically List<T> is the standard go-to collection when you don't have any other constraints, and typically we favor a List<T> even over arrays unless we are sure the size will remain absolutely fixed. The LinkedList<T> is a basic implementation of a doubly-linked list. This means that you can add or remove items in the middle of a linked list very quickly (because there's no items to move up or down in contiguous memory), but you also lose the ability to index items by position quickly. Most of the time we tend to favor List<T> over LinkedList<T> unless you are doing a lot of adding and removing from the collection, in which case a LinkedList<T> may make more sense. The HashSet<T> is an unordered collection of unique items. This means that the collection cannot have duplicates and no order is maintained. Logically, this is very similar to having a Dictionary<TKey,TValue> where the TKey and TValue both refer to the same object. This collection is very useful for maintaining a collection of items you wish to check membership against. For example, if you receive an order for a given vendor code, you may want to check to make sure the vendor code belongs to the set of vendor codes you handle. In these cases a HashSet<T> is useful for super-quick lookups where order is not important. Once again, like in Dictionary, the type T should have a valid implementation of GetHashCode() and Equals(), or you should provide an appropriate IEqualityComparer<T> to the HashSet<T> on construction. The SortedSet<T> is to HashSet<T> what the SortedDictionary<TKey,TValue> is to Dictionary<TKey,TValue>. That is, the SortedSet<T> is a binary tree where the key and value are the same object. This once again means that adding/removing/lookups are logarithmic - O(log n) - but you gain the ability to iterate over the items in order. For this collection to be effective, type T must implement IComparable<T> or you need to supply an external IComparer<T>. Finally, the Stack<T> and Queue<T> are two very specific collections that allow you to handle a sequential collection of objects in very specific ways. The Stack<T> is a last-in-first-out (LIFO) container where items are added and removed from the top of the stack. Typically this is useful in situations where you want to stack actions and then be able to undo those actions in reverse order as needed. The Queue<T> on the other hand is a first-in-first-out container which adds items at the end of the queue and removes items from the front. This is useful for situations where you need to process items in the order in which they came, such as a print spooler or waiting lines. So that's the basic collections. Let's summarize what we've learned in a quick reference table.  Collection Ordered? Contiguous Storage? Direct Access? Lookup Efficiency Manipulate Efficiency Notes Dictionary No Yes Via Key Key: O(1) O(1) Best for high performance lookups. SortedDictionary Yes No Via Key Key: O(log n) O(log n) Compromise of Dictionary speed and ordering, uses binary search tree. SortedList Yes Yes Via Key Key: O(log n) O(n) Very similar to SortedDictionary, except tree is implemented in an array, so has faster lookup on preloaded data, but slower loads. List No Yes Via Index Index: O(1) Value: O(n) O(n) Best for smaller lists where direct access required and no ordering. LinkedList No No No Value: O(n) O(1) Best for lists where inserting/deleting in middle is common and no direct access required. HashSet No Yes Via Key Key: O(1) O(1) Unique unordered collection, like a Dictionary except key and value are same object. SortedSet Yes No Via Key Key: O(log n) O(log n) Unique ordered collection, like SortedDictionary except key and value are same object. Stack No Yes Only Top Top: O(1) O(1)* Essentially same as List<T> except only process as LIFO Queue No Yes Only Front Front: O(1) O(1) Essentially same as List<T> except only process as FIFO   The Original Collections: System.Collections namespace The original collection classes are largely considered deprecated by developers and by Microsoft itself. In fact they indicate that for the most part you should always favor the generic or concurrent collections, and only use the original collections when you are dealing with legacy .NET code. Because these collections are out of vogue, let's just briefly mention the original collection and their generic equivalents: ArrayList A dynamic, contiguous collection of objects. Favor the generic collection List<T> instead. Hashtable Associative, unordered collection of key-value pairs of objects. Favor the generic collection Dictionary<TKey,TValue> instead. Queue First-in-first-out (FIFO) collection of objects. Favor the generic collection Queue<T> instead. SortedList Associative, ordered collection of key-value pairs of objects. Favor the generic collection SortedList<T> instead. Stack Last-in-first-out (LIFO) collection of objects. Favor the generic collection Stack<T> instead. In general, the older collections are non-type-safe and in some cases less performant than their generic counterparts. Once again, the only reason you should fall back on these older collections is for backward compatibility with legacy code and libraries only. The Concurrent Collections: System.Collections.Concurrent namespace The concurrent collections are new as of .NET 4.0 and are included in the System.Collections.Concurrent namespace. These collections are optimized for use in situations where multi-threaded read and write access of a collection is desired. The concurrent queue, stack, and dictionary work much as you'd expect. The bag and blocking collection are more unique. Below is the summary of each with a link to a blog post I did on each of them. ConcurrentQueue Thread-safe version of a queue (FIFO). For more information see: C#/.NET Little Wonders: The ConcurrentStack and ConcurrentQueue ConcurrentStack Thread-safe version of a stack (LIFO). For more information see: C#/.NET Little Wonders: The ConcurrentStack and ConcurrentQueue ConcurrentBag Thread-safe unordered collection of objects. Optimized for situations where a thread may be bother reader and writer. For more information see: C#/.NET Little Wonders: The ConcurrentBag and BlockingCollection ConcurrentDictionary Thread-safe version of a dictionary. Optimized for multiple readers (allows multiple readers under same lock). For more information see C#/.NET Little Wonders: The ConcurrentDictionary BlockingCollection Wrapper collection that implement producers & consumers paradigm. Readers can block until items are available to read. Writers can block until space is available to write (if bounded). For more information see C#/.NET Little Wonders: The ConcurrentBag and BlockingCollection Summary The .NET BCL has lots of collections built in to help you store and manipulate collections of data. Understanding how these collections work and knowing in which situations each container is best is one of the key skills necessary to build more performant code. Choosing the wrong collection for the job can make your code much slower or even harder to maintain if you choose one that doesn’t perform as well or otherwise doesn’t exactly fit the situation. Remember to avoid the original collections and stick with the generic collections.  If you need concurrent access, you can use the generic collections if the data is read-only, or consider the concurrent collections for mixed-access if you are running on .NET 4.0 or higher.   Tweet Technorati Tags: C#,.NET,Collecitons,Generic,Concurrent,Dictionary,List,Stack,Queue,SortedList,SortedDictionary,HashSet,SortedSet

  • Delphi Pascal - Using SetFilePointerEx and GetFileSizeEx, Getting Physical Media exact size when reading as a file

    - by SuicideClutchX2
    I am having trouble understanding how to delcare GetFileSizeEx and SetFilePointerEx in Delphi 2009 so that I can use them since they are not in the RTL or Windows.pas. I was able to compile with the following: function GetFileSizeEx(hFile: THandle; lpFileSizeHigh: Pointer): DWORD; external 'kernel32'; Then using GetFileSizeEx(PD, Pointer(DriveSize)); to get the size. But could not get it to work, the disk handle I am using is valid and I have had no problem reading the data or working under the 2gb mark with the older API's. GetFileSize of course returns 4294967295. I have had greater trouble trying to use SetFilePointerEx with the data types it uses. The overall project needs to read the data from a flash card, which is not a problem at all I can do this. My problem is that I can not find the length or size of the media I will be reading. I have code I have used in the past to do this with media under 2GB. But now that I need to read media over 2GB it is a problem. If you still dont understand I am dumping a card with all data including the boot record, etc. This is the code I would normally use to read from the physical disk to grab say the boot record and dump it to file: SetFilePointer(PD,0,nil,FILE_BEGIN); SetLength(Buffer,512); ReadFile(PD,Buffer[0],512,BytesReturned,nil); I just need to figure out how to find the end of an 8gb card and so on as well as being able to set a file pointer beyond the 2gb barrier. I guess any help in the external declarations as well as understand the values that SetFilePointerEx uses (I do not understand the whole High Low thing) would be of great help. var Form1: TForm1; function GetFileSizeEx(hFile: THandle; var FileSize: Int64): DWORD; stdcall; external 'kernel32'; implementation {$R *.dfm} function GetLD(Drive: Char): Cardinal; var Buffer : String; begin Buffer := Format('\\.\%s:',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPD(Drive: Byte): Cardinal; var Buffer : String; begin If Drive = 0 Then begin Result := INVALID_HANDLE_VALUE; Exit; end; Buffer := Format('\\.\PHYSICALDRIVE%d',[Drive]); Result := CreateFile(PChar(Buffer),GENERIC_READ Or GENERIC_WRITE,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); If Result = INVALID_HANDLE_VALUE Then begin Result := CreateFile(PChar(Buffer),GENERIC_READ,FILE_SHARE_READ,nil,OPEN_EXISTING,0,0); end; end; function GetPhysicalDiskNumber(Drive: Char): Byte; var LD : DWORD; DiskExtents : PVolumeDiskExtents; DiskExtent : TDiskExtent; BytesReturned : Cardinal; begin Result := 0; LD := GetLD(Drive); If LD = INVALID_HANDLE_VALUE Then Exit; Try DiskExtents := AllocMem(Max_Path); DeviceIOControl(LD,IOCTL_VOLUME_GET_VOLUME_DISK_EXTENTS,nil,0,DiskExtents,Max_Path,BytesReturned,nil); If DiskExtents^.NumberOfDiskExtents > 0 Then begin DiskExtent := DiskExtents^.Extents[0]; Result := DiskExtent.DiskNumber; end; Finally CloseHandle(LD); end; end; procedure TForm1.Button1Click(Sender: TObject); var PD : DWORD; BytesReturned : Cardinal; Buffer : Array Of Byte; myFile: File; DriveSize: Int64; begin PD := GetPD(GetPhysicalDiskNumber(Edit1.Text[1])); If PD = INVALID_HANDLE_VALUE Then Exit; Try GetFileSizeEx(PD, DriveSize); //SetFilePointer(PD,0,nil,FILE_BEGIN); //etLength(Buffer,512); //ZeroMemory(@Buffer,SizeOf(Buffer)); //ReadFile(PD,Buffer[0],512,BytesReturned,nil); //AssignFile(myFile, 'StickDump.bin'); //ReWrite(myFile, 512); //BlockWrite(myFile, Buffer[0], 1); //CloseFile(myFile); Finally CloseHandle(PD); End; end;

  • Why is my WCF RIA Services custom object deserializing with an extra list member?

    - by oasasaurus
    I have been developing a Silverlight WCF RIA Services application dealing with mock financial transactions. To more efficiently send summary data to the client without going overboard with serialized entities I have created a summary class that isn’t in my EDM, and figured out how to serialize and send it over the wire to the SL client using DataContract() and DataMember(). Everything seemed to be working out great, until I tried to bind controls to a list inside my custom object. The list seems to always get deserialized with an extra, almost empty entity in it that I don’t know how to get rid of. So, here are some of the pieces. First the relevant bits from the custom object class: <DataContract()> _ Public Class EconomicsSummary Public Sub New() RecentTransactions = New List(Of Transaction) TotalAccountHistory = New List(Of Transaction) End Sub Public Sub New(ByVal enUser As EntityUser) Me.UserId = enUser.UserId Me.UserName = enUser.UserName Me.Accounts = enUser.Accounts Me.Jobs = enUser.Jobs RecentTransactions = New List(Of Transaction) TotalAccountHistory = New List(Of Transaction) End Sub <DataMember()> _ <Key()> _ Public Property UserId As System.Guid <DataMember()> _ Public Property NumTransactions As Integer <DataMember()> _ <Include()> _ <Association("Summary_RecentTransactions", "UserId", "User_UserId")> _ Public Property RecentTransactions As List(Of Transaction) <DataMember()> _ <Include()> _ <Association("Summary_TotalAccountHistory", "UserId", "User_UserId")> _ Public Property TotalAccountHistory As List(Of Transaction) End Class Next, the relevant parts of the function called to return the object: Public Function GetEconomicsSummary(ByVal guidUserId As System.Guid) As EconomicsSummary Dim objOutput As New EconomicsSummary(enUser) For Each objTransaction As Transaction In (From t As Transaction In Me.ObjectContext.Transactions.Include("Account") Where t.Account.aspnet_User_UserId = guidUserId Select t Order By t.TransactionDate Descending Take 10) objTransaction.User_UserId = objOutput.UserId objOutput.RecentTransactions.Add(objTransaction) Next objOutput.NumTransactions = objOutput.RecentTransactions.Count … Return objOutput End Function Notice that I’m collecting the NumTransactions count before serialization. Should be 10 right? It is – BEFORE serialization. The DataGrid is bound to the data source as follows: <sdk:DataGrid AutoGenerateColumns="False" Height="100" MaxWidth="{Binding ElementName=aciSummary, Path=ActualWidth}" ItemsSource="{Binding Source={StaticResource EconomicsSummaryRecentTransactionsViewSource}, Mode=OneWay}" Name="gridRecentTransactions" RowDetailsVisibilityMode="VisibleWhenSelected" IsReadOnly="True"> <sdk:DataGrid.Columns> <sdk:DataGridTextColumn x:Name="TransactionDateColumn" Binding="{Binding Path=TransactionDate, StringFormat=\{0:d\}}" Header="Date" Width="SizeToHeader" /> <sdk:DataGridTextColumn x:Name="AccountNameColumn" Binding="{Binding Path=Account.Title}" Header="Account" Width="SizeToCells" /> <sdk:DataGridTextColumn x:Name="CurrencyAmountColumn" Binding="{Binding Path=CurrencyAmount, StringFormat=\{0:c\}}" Header="Amount" Width="SizeToHeader" /> <sdk:DataGridTextColumn x:Name="TitleColumn" Binding="{Binding Path=Title}" Header="Description" Width="SizeToCells" /> <sdk:DataGridTextColumn x:Name="ItemQuantityColumn" Binding="{Binding Path=ItemQuantity}" Header="Qty" Width="SizeToHeader" /> </sdk:DataGrid.Columns> </sdk:DataGrid> You might be wondering where the ItemsSource is coming from, that looks like this: <CollectionViewSource x:Key="EconomicsSummaryRecentTransactionsViewSource" Source="{Binding Path=DataView.RecentTransactions, ElementName=EconomicsSummaryDomainDataSource}" /> When I noticed that the DataGrid had the extra row I tried outputting some data after the data source finishes loading, as follows: Private Sub EconomicsSummaryDomainDataSource_LoadedData(ByVal sender As System.Object, ByVal e As System.Windows.Controls.LoadedDataEventArgs) Handles EconomicsSummaryDomainDataSource.LoadedData If e.HasError Then System.Windows.MessageBox.Show(e.Error.ToString, "Load Error", System.Windows.MessageBoxButton.OK) e.MarkErrorAsHandled() End If Dim objSummary As EconomicsSummary = CType(EconomicsSummaryDomainDataSource.Data(0), EconomicsSummary) Dim sb As New StringBuilder("") sb.AppendLine(String.Format("Num Transactions: {0} ({1})", objSummary.RecentTransactions.Count.ToString(), objSummary.NumTransactions.ToString())) For Each objTransaction As Transaction In objSummary.RecentTransactions sb.AppendLine(String.Format("Recent TransactionId {0} dated {1} CurrencyAmount {2} NewBalance {3}", objTransaction.TransactionId.ToString, objTransaction.TransactionDate.ToString("d"), objTransaction.CurrencyAmount.ToString("c"), objTransaction.NewBalance.ToString("c"))) Next txtDebug.Text = sb.ToString() End Sub Output from that looks like this: Num Transactions: 11 (10) Recent TransactionId 2283 dated 6/1/2010 CurrencyAmount $31.00 NewBalance $392.00 Recent TransactionId 2281 dated 5/31/2010 CurrencyAmount $33.00 NewBalance $361.00 Recent TransactionId 2279 dated 5/28/2010 CurrencyAmount $8.00 NewBalance $328.00 Recent TransactionId 2277 dated 5/26/2010 CurrencyAmount $22.00 NewBalance $320.00 Recent TransactionId 2275 dated 5/24/2010 CurrencyAmount $5.00 NewBalance $298.00 Recent TransactionId 2273 dated 5/21/2010 CurrencyAmount $19.00 NewBalance $293.00 Recent TransactionId 2271 dated 5/20/2010 CurrencyAmount $20.00 NewBalance $274.00 Recent TransactionId 2269 dated 5/19/2010 CurrencyAmount $48.00 NewBalance $254.00 Recent TransactionId 2267 dated 5/18/2010 CurrencyAmount $42.00 NewBalance $206.00 Recent TransactionId 2265 dated 5/14/2010 CurrencyAmount $5.00 NewBalance $164.00 Recent TransactionId 0 dated 6/1/2010 CurrencyAmount $0.00 NewBalance $361.00 So I have a few different questions: -First and foremost, where the devil is that extra Transaction entity coming from and how do I get rid of it? Does it have anything to do with the other list of Transaction entities being serialized as part of the EconomicsSummary class (TotalAccountHistory)? Do I need to decorate the EconomicsSummary class members a little more/differently? -Second, where are the peculiar values coming from on that extra entity? PRE-POSTING UPDATE 1: I did a little checking, it looks like that last entry is the first one in the TotalAccountHistory list. Do I need to do something with CollectionDataContract()? PRE-POSTING UPDATE 2: I fixed one bug in TotalAccountHistory, since the objects weren’t coming from the database their keys weren’t unique. So I set the keys on the Transaction entities inside TotalAccountHistory to be unique and guess what? Now, after deserialization RecentTransactions contains all its original items, plus every item in TotalAccountHistory. I’m pretty sure this has to do with the deserializer getting confused by two collections of the same type. But I don’t yet know how to resolve it…

  • Getting template metaprogramming compile-time constants at runtime

    - by GMan - Save the Unicorns
    Background Consider the following: template <unsigned N> struct Fibonacci { enum { value = Fibonacci<N-1>::value + Fibonacci<N-2>::value }; }; template <> struct Fibonacci<1> { enum { value = 1 }; }; template <> struct Fibonacci<0> { enum { value = 0 }; }; This is a common example and we can get the value of a Fibonacci number as a compile-time constant: int main(void) { std::cout << "Fibonacci(15) = "; std::cout << Fibonacci<15>::value; std::cout << std::endl; } But you obviously cannot get the value at runtime: int main(void) { std::srand(static_cast<unsigned>(std::time(0))); // ensure the table exists up to a certain size // (even though the rest of the code won't work) static const unsigned fibbMax = 20; Fibonacci<fibbMax>::value; // get index into sequence unsigned fibb = std::rand() % fibbMax; std::cout << "Fibonacci(" << fibb << ") = "; std::cout << Fibonacci<fibb>::value; std::cout << std::endl; } Because fibb is not a compile-time constant. Question So my question is: What is the best way to peek into this table at run-time? The most obvious solution (and "solution" should be taken lightly), is to have a large switch statement: unsigned fibonacci(unsigned index) { switch (index) { case 0: return Fibonacci<0>::value; case 1: return Fibonacci<1>::value; case 2: return Fibonacci<2>::value; . . . case 20: return Fibonacci<20>::value; default: return fibonacci(index - 1) + fibonacci(index - 2); } } int main(void) { std::srand(static_cast<unsigned>(std::time(0))); static const unsigned fibbMax = 20; // get index into sequence unsigned fibb = std::rand() % fibbMax; std::cout << "Fibonacci(" << fibb << ") = "; std::cout << fibonacci(fibb); std::cout << std::endl; } But now the size of the table is very hard coded and it wouldn't be easy to expand it to say, 40. The only one I came up with that has a similiar method of query is this: template <int TableSize = 40> class FibonacciTable { public: enum { max = TableSize }; static unsigned get(unsigned index) { if (index == TableSize) { return Fibonacci<TableSize>::value; } else { // too far, pass downwards return FibonacciTable<TableSize - 1>::get(index); } } }; template <> class FibonacciTable<0> { public: enum { max = 0 }; static unsigned get(unsigned) { // doesn't matter, no where else to go. // must be 0, or the original value was // not in table return 0; } }; int main(void) { std::srand(static_cast<unsigned>(std::time(0))); // get index into sequence unsigned fibb = std::rand() % FibonacciTable<>::max; std::cout << "Fibonacci(" << fibb << ") = "; std::cout << FibonacciTable<>::get(fibb); std::cout << std::endl; } Which seems to work great. The only two problems I see are: Potentially large call stack, since calculating Fibonacci<2 requires we go through TableMax all the way to 2, and: If the value is outside of the table, it returns zero as opposed to calculating it. So is there something I am missing? It seems there should be a better way to pick out these values at runtime. A template metaprogramming version of a switch statement perhaps, that generates a switch statement up to a certain number? Thanks in advance.

  • OData to the rescue. Exposing the eventlog as a data feed

    - by cibrax
    In one of the project where I was working one, we used the Microsoft Enterprise Library Exception Application Block integration with WCF for logging all the technical issues on the services/backend in Windows Event Log. This application block worked like a charm, all the errors were correctly logged on the Event Log without even needing to modify the service code. However, we also needed to provide a quick way to expose all those events to the different system users so they could get access to all the them remotely. In just a couple of minutes I came up with a simple solution based on ADO.NET Data Services. ADO.NET data services is very powerful in this sense, you only need to provide a IQueryable implementation, and that’s all. You get a RESTful service with rich query support for free. In this sample, I used Linq to Objects to get the latest entries from the Event Log, and I also filter the entries by the category used by the Application Block to avoid loading unnecessary entries in memory. public class LogDataSource     {         string source;         public LogDataSource(string source)         {             this.source = source;         }         public LogDataSource()         {         }         public IQueryable<LogEntry> LogEntries         {             get { return GetEntries().AsQueryable().OrderBy(e => e.TimeGenerated); }         }         private IEnumerable<LogEntry> GetEntries()         {             var applicationLog = System.Diagnostics.EventLog.GetEventLogs().Where(e => e.Log == "Application")                 .FirstOrDefault();             var entries = new List<LogEntry>();             if (applicationLog != null)             {                 foreach (EventLogEntry entry in applicationLog.Entries)                 {                     if (source == null || entry.Source.Equals(source, StringComparison.InvariantCultureIgnoreCase))                     {                         entries.Add(new LogEntry                         {                             Category = entry.Category,                             EventID = entry.InstanceId,                             Message = entry.Message,                             TimeGenerated = entry.TimeGenerated,                             Source = entry.Source,                         });                     }                 }             }             return entries.OrderByDescending(e => e.TimeGenerated)                         .Take(200);         }     } LogEntry is class I created for this service to expose an Event Log Entry.     [EntityPropertyMappingAttribute("Source",         SyndicationItemProperty.Title,         SyndicationTextContentKind.Plaintext, true)]     [EntityPropertyMapping("Message",         SyndicationItemProperty.Summary,         SyndicationTextContentKind.Plaintext, true)]     [EntityPropertyMapping("TimeGenerated",         SyndicationItemProperty.Updated,         SyndicationTextContentKind.Plaintext, true)]     [DataServiceKey("EventID")]     public class LogEntry     {         public long EventID         {             get;             set;         }         public string Category         {             get;             set;         }         public string Message         {             get;             set;         }         public DateTime TimeGenerated         {             get;             set;         }         public string Source         {             get;             set;         }     } As you can see, I used the new feature “Friendly feeds” to map several properties in the entries with standard ATOM elements. The “DataServiceKey” is only necessary because I am using the Reflection Provider (the exposed IQueryable implementation is just Linq to Objects) rather than the default Entity Framework Provider. The data service implementation is also quite simple, just a couple of lines were needed to expose the data source created previously. public class LogDataService : DataService<LogDataSource>     {         public static void InitializeService(IDataServiceConfiguration config)         {             config.SetEntitySetAccessRule("*", EntitySetRights.AllRead);         }         protected override LogDataSource CreateDataSource()         {             string source = ConfigurationManager.AppSettings["EventLogSource"];             if (source == null)             {                 throw new ApplicationException("The EventLogSource appsetting is missing in the configuration file");             }             return new LogDataSource(source);         }     } With this implementation in place, the final users not only get a feed with all the latest errors in the event log, but also support for performing queries against that data. This is one of the great things about ADO.NET Data services.

  • Using the Data Form Web Part (SharePoint 2010) Site Agnostically!

    - by David Jacobus
    Originally posted on: http://geekswithblogs.net/djacobus/archive/2013/10/24/154465.aspxAs a Developer whom has worked closely with web designers (Power users) in a SharePoint environment, I have come across the issue of making the Data Form Web Part reusable across the site collection! In SharePoint 2007 it was very easy and this blog pointed the way to make it happen: Josh Gaffey's Blog. In SharePoint 2010 something changed! This method failed except for using a Data Form Web Part that pointed to a list in the Site Collection Root! I am making this discussion relative to a developer whom creates a solution (WSP) with all the artifacts embedded and the user shouldn’t have any involvement in the process except to activate features. The Scenario: 1. A Power User creates a Data Form Web Part using SharePoint Designer 2010! It is a great web part the uses all the power of SharePoint Designer and XSLT (Conditional formatting, etc.). 2. Other Users in the site collection want to use that specific web part in sub sites in the site collection. Pointing to a list with the same name, not at the site collection root! The Issues: 1. The Data Form Web Part Data Source uses a List ID (GUID) to point to the specific list. Which means a list in a sub site will have a list with a new GUID different than the one which was created with SharePoint Designer! Obviously, the List needs to be the same List (Fields, Content Types, etc.) with different data. 2. How can we make this web part site agnostic, and dependent only on the lists Name? I had this problem come up over and over and decided to put my solution forward! The Solution: 1. Use the XSL of the Data Form Web Part Created By the Power User in SharePoint Designer! 2. Extend the OOTB Data Form Web Part to use this XSL and Point to a List by name. The solution points to a hybrid solution that requires some coding (Developer) and the XSL (Power User) artifacts put together in a Visual Studio SharePoint Solution. Here are the solution steps in summary: 1. Create an empty SharePoint project in Visual Studio 2. Create a Module and Feature and put the XSL file created by the Power User into it a. Scope the feature to web 3. Create a Feature Receiver to Create the List. The same list from which the Data Form Web Part was created with by the Power User. a. Scope the feature to web 4. Create a Web Part extending the Data Form Web a. Point the Data Form Web Part to point to the List by Name b. Point the Data Form Web Part XSL link to the XSL added using the Module feature c. Scope The feature to Site i. This is because all web parts are in the site collection web part gallery. So in a Narrative Summary: We are creating a list in code which has the same name and (site Columns) as the list from which the Power User created the Data Form Web Part Using SharePoint Designer. We are creating a Web Part in code which extends the OOTB Data Form Web Part to point to a list by name and use the XSL created by the Power User. Okay! Here are the steps with images and code! At the end of this post I will provide a link to the code for a solution which works in any site! I want to TOOT the HORN for the power of this solution! It is the mantra a use with all my clients! What is a basic skill a SharePoint Developer: Create an application that uses the data from a SharePoint list and make that data visible to the user in a manner which meets requirements! Create an Empty SharePoint 2010 Project Here I am naming my Project DJ.DataFormWebPart Create a Code Folder Copy and paste the Extension and Utilities classes (Found in the solution provided at the end of this post) Change the Namespace to match this project The List to which the Data Form Web Part which was used to make the XSL by the Power User in SharePoint Designer is now going to be created in code! If already in code, then all the better! Here I am going to create a list in the site collection root and add some data to it! For the purpose of this discussion I will actually create this list in code before using SharePoint Designer for simplicity! So here I create the List and deploy it within this solution before I do anything else. I will use a List I created before for demo purposes. Footer List is used within the footer of my master page. Add a new Feature: Here I name the Feature FooterList and add a Feature Event Receiver: Here is the code for the Event Receiver: I have a previous blog post about adding lists in code so I will not take time to narrate this code: using System; using System.Runtime.InteropServices; using System.Security.Permissions; using Microsoft.SharePoint; using DJ.DataFormWebPart.Code; namespace DJ.DataFormWebPart.Features.FooterList { /// <summary> /// This class handles events raised during feature activation, deactivation, installation, uninstallation, and upgrade. /// </summary> /// <remarks> /// The GUID attached to this class may be used during packaging and should not be modified. /// </remarks> [Guid("a58644fd-9209-41f4-aa16-67a53af7a9bf")] public class FooterListEventReceiver : SPFeatureReceiver { SPWeb currentWeb = null; SPSite currentSite = null; const string columnGroup = "DJ"; const string ctName = "FooterContentType"; // Uncomment the method below to handle the event raised after a feature has been activated. public override void FeatureActivated(SPFeatureReceiverProperties properties) { using (SPWeb spWeb = properties.GetWeb() as SPWeb) { using (SPSite site = new SPSite(spWeb.Site.ID)) { using (SPWeb rootWeb = site.OpenWeb(site.RootWeb.ID)) { //add the fields addFields(rootWeb); //add content type SPContentType testCT = rootWeb.ContentTypes[ctName]; // we will not create the content type if it exists if (testCT == null) { //the content type does not exist add it addContentType(rootWeb, ctName); } if ((spWeb.Lists.TryGetList("FooterList") == null)) { //create the list if it dosen't to exist CreateFooterList(spWeb, site); } } } } } #region ContentType public void addFields(SPWeb spWeb) { Utilities.addField(spWeb, "Link", SPFieldType.URL, false, columnGroup); Utilities.addField(spWeb, "Information", SPFieldType.Text, false, columnGroup); } private static void addContentType(SPWeb spWeb, string name) { SPContentType myContentType = new SPContentType(spWeb.ContentTypes["Item"], spWeb.ContentTypes, name) { Group = columnGroup }; spWeb.ContentTypes.Add(myContentType); addContentTypeLinkages(spWeb, myContentType); myContentType.Update(); } public static void addContentTypeLinkages(SPWeb spWeb, SPContentType ct) { Utilities.addContentTypeLink(spWeb, "Link", ct); Utilities.addContentTypeLink(spWeb, "Information", ct); } private void CreateFooterList(SPWeb web, SPSite site) { Guid newListGuid = web.Lists.Add("FooterList", "Footer List", SPListTemplateType.GenericList); SPList newList = web.Lists[newListGuid]; newList.ContentTypesEnabled = true; var footer = site.RootWeb.ContentTypes[ctName]; newList.ContentTypes.Add(footer); newList.ContentTypes.Delete(newList.ContentTypes["Item"].Id); newList.Update(); var view = newList.DefaultView; //add all view fields here //view.ViewFields.Add("NewsTitle"); view.ViewFields.Add("Link"); view.ViewFields.Add("Information"); view.Update(); } } } Basically created a content type with two site columns Link and Information. I had to change some code as we are working at the SPWeb level and need Content Types at the SPSite level! I’ll use a new Site Collection for this demo (Best Practice) keep old artifacts from impinging on development: Next we will add this list to the root of the site collection by deploying this solution, add some data and then use SharePoint Designer to create a Data Form Web Part. The list has been added, now let’s add some data: Okay let’s add a Data Form Web Part in SharePoint Designer. Create a new web part page in the site pages library: I will name it TestWP.aspx and edit it in advanced mode: Let’s add an empty Data Form Web Part to the web part zone: Click on the web part to add a data source: Choose FooterList in the Data Source menu: Choose appropriate fields and select insert as multiple item view: Here is what it look like after insertion: Let’s add some conditional formatting if the information filed is not blank: Choose Create (right side) apply formatting: Choose the Information Field and set the condition not null: Click Set Style: Here is the result: Okay! Not flashy but simple enough for this demo. Remember this is the job of the Power user! All we want from this web part is the XLS-Style Sheet out of SharePoint Designer. We are going to use it as the XSL for our web part which we will be creating next. Let’s add a web part to our project extending the OOTB Data Form Web Part. Add new item from the Visual Studio add menu: Choose Web Part: Change WebPart to DataFormWebPart (Oh well my namespace needs some improvement, but it will sure make it readily identifiable as an extended web part!) Below is the code for this web part: using System; using System.ComponentModel; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using Microsoft.SharePoint; using Microsoft.SharePoint.WebControls; using System.Text; namespace DJ.DataFormWebPart.DataFormWebPart { [ToolboxItemAttribute(false)] public class DataFormWebPart : Microsoft.SharePoint.WebPartPages.DataFormWebPart { protected override void OnInit(EventArgs e) { base.OnInit(e); this.ChromeType = PartChromeType.None; this.Title = "FooterListDF"; try { //SPSite site = SPContext.Current.Site; SPWeb web = SPContext.Current.Web; SPList list = web.Lists.TryGetList("FooterList"); if (list != null) { string queryList1 = "<Query><Where><IsNotNull><FieldRef Name='Title' /></IsNotNull></Where><OrderBy><FieldRef Name='Title' Ascending='True' /></OrderBy></Query>"; uint maximumRowList1 = 10; SPDataSource dataSourceList1 = GetDataSource(list.Title, web.Url, list, queryList1, maximumRowList1); this.DataSources.Add(dataSourceList1); this.XslLink = web.Url + "/Assests/Footer.xsl"; this.ParameterBindings = BuildDataFormParameters(); this.DataBind(); } } catch (Exception ex) { this.Controls.Add(new LiteralControl("ERROR: " + ex.Message)); } } private SPDataSource GetDataSource(string dataSourceId, string webUrl, SPList list, string query, uint maximumRow) { SPDataSource dataSource = new SPDataSource(); dataSource.UseInternalName = true; dataSource.ID = dataSourceId; dataSource.DataSourceMode = SPDataSourceMode.List; dataSource.List = list; dataSource.SelectCommand = "" + query + ""; Parameter listIdParam = new Parameter("ListID"); listIdParam.DefaultValue = list.ID.ToString( "B").ToUpper(); Parameter maximumRowsParam = new Parameter("MaximumRows"); maximumRowsParam.DefaultValue = maximumRow.ToString(); QueryStringParameter rootFolderParam = new QueryStringParameter("RootFolder", "RootFolder"); dataSource.SelectParameters.Add(listIdParam); dataSource.SelectParameters.Add(maximumRowsParam); dataSource.SelectParameters.Add(rootFolderParam); dataSource.UpdateParameters.Add(listIdParam); dataSource.DeleteParameters.Add(listIdParam); dataSource.InsertParameters.Add(listIdParam); return dataSource; } private string BuildDataFormParameters() { StringBuilder parameters = new StringBuilder("<ParameterBindings><ParameterBinding Name=\"dvt_apos\" Location=\"Postback;Connection\"/><ParameterBinding Name=\"UserID\" Location=\"CAMLVariable\" DefaultValue=\"CurrentUserName\"/><ParameterBinding Name=\"Today\" Location=\"CAMLVariable\" DefaultValue=\"CurrentDate\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_firstrow\" Location=\"Postback;Connection\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_nextpagedata\" Location=\"Postback;Connection\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_adhocmode\" Location=\"Postback;Connection\"/>"); parameters.Append("<ParameterBinding Name=\"dvt_adhocfiltermode\" Location=\"Postback;Connection\"/>"); parameters.Append("</ParameterBindings>"); return parameters.ToString(); } } } The OnInit method we use to set the list name and the XSL Link property of the Data Form Web Part. We do not have the link to XSL in our Solution so we will add the XSL now: Add a Module in the Visual Studio add menu: Rename Sample.txt in the module to footer.xsl and then copy the XSL from SharePoint Designer Look at elements.xml to where the footer.xsl is being provisioned to which is Assets/footer.xsl, make sure the Web parts xsl link is pointing to this url: Okay we are good to go! Let’s check our features and package: DataFormWebPart should be scoped to site and have the web part: The Footer List feature should be scoped to web and have the Assets module (Okay, I see, a spelling issue but it won’t affect this demo) If everything is correct we should be able to click a couple of sub site feature activations and have our list and web part in a sub site. (In fact this solution can be activated anywhere) Here is the list created at SubSite1 with new data It. Next let’s add the web part on a test page and see if it works as expected: It does! So we now have a repeatable way to use a WSP to move a Data Form Web Part around our sites! Here is a link to the code: DataFormWebPart Solution
