How to deploy Document Set using CAML in SharePoint2010 solution package

- by ybbest

In my last post, I showed you how to use Document Set using SharePoint UI in the browser. In this post, I’d like to show you how to create the same Document Set using CAML and SharePoint solution package. You can download the complete solution here. 1. Create the Application Number site column using the SharePoint empty element item template in VS2010 <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <Field Type="Text" DisplayName="ApplicationNumber" Required="FALSE" EnforceUniqueValues="FALSE" Indexed="FALSE" MaxLength="255" Group="YBBEST" ID="{916bf3af-5ec1-4441-acd8-88ff62ab1b7e}" Name="ApplicationNumber" ></Field> </Elements> 2. Create the Loan Application Form and Loan Contract Form content types. <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/">  <ContentType ID="0x0101005dfbf820ce3c49f69c73a00e0e0e53f6" Name="Loan Contract Form" Group="YBBEST" Description="Loan Contract Form" Inherits="TRUE" Version="0"> <FieldRefs> <FieldRef ID="916bf3af-5ec1-4441-acd8-88ff62ab1b7e" Name="ApplicationNumber" DisplayName="ApplicationNumber" /> </FieldRefs> </ContentType>  <ContentType ID="0x010100f3016e3d03454b93bc4d6ab63941c0d2" Name="Loan Application Form" Group="YBBEST" Description="Loan Application Form" Inherits="TRUE" Version="0"> <FieldRefs> <FieldRef ID="916bf3af-5ec1-4441-acd8-88ff62ab1b7e" Name="ApplicationNumber" DisplayName="ApplicationNumber" /> </FieldRefs> </ContentType> </Elements> 3. Create the Loan Application Document Set. 4. Create the Document Set Welcome Page using the SharePoint Module item template. Notes: 1.When creating document set content type , you need to set the Inherits=”FALSE” or remove the Inherits=”TRUE” from the content type definition (default is Inherits=”FALSE”) . This is the Document Set limitation in the current version of SharePoint2010. Because of this , you also need to manually attach the event receiver and Document Set welcome page to your custom Document Set Content Type. 2. Shared Fields are push down only: 3. Not available in SharePoint foundation (only SharePoint Server 2010). 4. You can’t have folders within document sets (you can place document sets in folders though). For a complete limitation and considerations , you can see the references for details.

using Generics in C# [closed]

- by Uphaar Goyal

I have started looking into using generics in C#. As an example what i have done is that I have an abstract class which implements generic methods. these generic methods take a sql query, a connection string and the Type T as parameters and then construct the data set, populate the object and return it back. This way each business object does not need to have a method to populate it with data or construct its data set. All we need to do is pass the type, the sql query and the connection string and these methods do the rest.I am providing the code sample here. I am just looking to discuss with people who might have a better solution to what i have done. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Data; using System.Data.SqlClient; using MWTWorkUnitMgmtLib.Business; using System.Collections.ObjectModel; using System.Reflection; namespace MWTWorkUnitMgmtLib.TableGateway { public abstract class TableGateway { public TableGateway() { } protected abstract string GetConnection(); protected abstract string GetTableName(); public DataSet GetDataSetFromSql(string connectionString, string sql) { DataSet ds = null; using (SqlConnection connection = new SqlConnection(connectionString)) using (SqlCommand command = connection.CreateCommand()) { command.CommandText = sql; connection.Open(); using (ds = new DataSet()) using (SqlDataAdapter adapter = new SqlDataAdapter(command)) { adapter.Fill(ds); } } return ds; } public static bool ContainsColumnName(DataRow dr, string columnName) { return dr.Table.Columns.Contains(columnName); } public DataTable GetDataTable(string connString, string sql) { DataSet ds = GetDataSetFromSql(connString, sql); DataTable dt = null; if (ds != null) { if (ds.Tables.Count 0) { dt = ds.Tables[0]; } } return dt; } public T Construct(DataRow dr, T t) where T : class, new() { Type t1 = t.GetType(); PropertyInfo[] properties = t1.GetProperties(); foreach (PropertyInfo property in properties) { if (ContainsColumnName(dr, property.Name) && (dr[property.Name] != null)) property.SetValue(t, dr[property.Name], null); } return t; } public T GetByID(string connString, string sql, T t) where T : class, new() { DataTable dt = GetDataTable(connString, sql); DataRow dr = dt.Rows[0]; return Construct(dr, t); } public List GetAll(string connString, string sql, T t) where T : class, new() { List collection = new List(); DataTable dt = GetDataTable(connString, sql); foreach (DataRow dr in dt.Rows) collection.Add(Construct(dr, t)); return collection; } } }

Enhanced REST Support in Oracle Service Bus 11gR1

- by jeff.x.davies

In a previous entry on REST and Oracle Service Bus (see http://blogs.oracle.com/jeffdavies/2009/06/restful_services_with_oracle_s_1.html) I encoded the REST query string really as part of the relative URL. For example, consider the following URI: http://localhost:7001/SimpleREST/Products/id=1234 Now, technically there is nothing wrong with this approach. However, it is generally more common to encode the search parameters into the query string. Take a look at the following URI that shows this principle http://localhost:7001/SimpleREST/Products?id=1234 At first blush this appears to be a trivial change. However, this approach is more intuitive, especially if you are passing in multiple parameters. For example: http://localhost:7001/SimpleREST/Products?cat=electronics&subcat=television&mfg=sony The above URI is obviously used to retrieve a list of televisions made by Sony. In prior versions of OSB (before 11gR1PS3), parsing the query string of a URI was more difficult than in the current release. In 11gR1PS3 it is now much easier to parse the query strings, which in turn makes developing REST services in OSB even easier. In this blog entry, we will re-implement the REST-ful Products services using query strings for passing parameter information. Lets begin with the implementation of the Products REST service. This service is implemented in the Products.proxy file of the project. Lets begin with the overall structure of the service, as shown in the following screenshot. This is a common pattern for REST services in the Oracle Service Bus. You implement different flows for each of the HTTP verbs that you want your service to support. Lets take a look at how the GET verb is implemented. This is the path that is taken of you were to point your browser to: http://localhost:7001/SimpleREST/Products/id=1234 There is an Assign action in the request pipeline that shows how to extract a query parameter. Here is the expression that is used to extract the id parameter: $inbound/ctx:transport/ctx:request/http:query-parameters/http:parameter[@name="id"]/@value The Assign action that stores the value into an OSB variable named id. Using this type of XPath statement you can query for any variables by name, without regard to their order in the parameter list. The Log statement is there simply to provided some debugging info in the OSB server console. The response pipeline contains a Replace action that constructs the response document for our rest service. Most of the response data is static, but the ID field that is returned is set based upon the query-parameter that was passed into the REST proxy. Testing the REST service with a browser is very simple. Just point it to the URL I showed you earlier. However, the browser is really only good for testing simple GET services. The OSB Test Console provides a much more robust environment for testing REST services, no matter which HTTP verb is used. Lets see how to use the Test Console to test this GET service. Open the OSB we console (http://localhost:7001/sbconsole) and log in as the administrator. Click on the Test Console icon (the little "bug") next to the Products proxy service in the SimpleREST project. This will bring up the Test Console browser window. Unlike SOAP services, we don't need to do much work in the request document because all of our request information will be encoded into the URI of the service itself. Belore the Request Document section of the Test Console is the Transport section. Expand that section and modify the query-parameters and http-method fields as shown in the next screenshot. By default, the query-parameters field will have the tags already defined. You just need to add a tag for each parameter you want to pass into the service. For out purposes with this particular call, you'd set the quer-parameters field as follows: <tp:parameter name="id" value="1234" /> </tp:query-parameters> Now you are ready to push the Execute button to see the results of the call. That covers the process for parsing query parameters using OSB. However, what if you have an OSB proxy service that needs to consume a REST-ful service? How do you tell OSB to pass the query parameters to the external service? In the sample code you will see a 2nd proxy service called CallREST. It invokes the Products proxy service in exactly the same way it would invoke any REST service. Our CallREST proxy service is defined as a SOAP service. This help to demonstrate OSBs ability to mediate between service consumers and service providers, decreasing the level of coupling between them. If you examine the message flow for the CallREST proxy service, you'll see that it uses an Operational branch to isolate processing logic for each operation that is defined by the SOAP service. We will focus on the getProductDetail branch, that calls the Products REST service using the HTTP GET verb. Expand the getProduct pipeline and the stage node that it contains. There is a single Assign statement that simply extracts the productID from the SOA request and stores it in a local OSB variable. Nothing suprising here. The real work (and the real learning) occurs in the Route node below the pipeline. The first thing to learn is that you need to use a route node when calling REST services, not a Service Callout or a Publish action. That's because only the Routing action has access to the $oubound variable, especially when invoking a business service. The Routing action contains 3 Insert actions. The first Insert action shows how to specify the HTTP verb as a GET. The second insert action simply inserts the XML node into the request. This element does not exist in the request by default, so we need to add it manually. Now that we have the element defined in our outbound request, we can fill it with the parameters that we want to send to the REST service. In the following screenshot you can see how we define the id parameter based on the productID value we extracted earlier from the SOAP request document. That expression will look for the parameter that has the name id and extract its value. That's all there is to it. You now know how to take full advantage of the query parameter parsing capability of the Oracle Service Bus 11gR1PS2. Download the sample source code here: rest2_sbconfig.jar Ubuntu and the OSB Test Console You will get an error when you try to use the Test Console with the Oracle Service Bus, using Ubuntu (or likely a number of other Linux distros also). The error (shown below) will state that the Test Console service is not running. The fix for this problem is quite simple. Open up the WebLogic Server administrator console (usually running at http://localhost:7001/console). In the Domain Structure window on the left side of the console, select the Servers entry under the Environment heading. The select the Admin Server entry in the main window of the console. By default, you should be viewing the Configuration tabe and the General sub tab in the main window. Look for the Listen Address field. By default it is blank, which means it is listening on all interfaces. For some reason Ubuntu doesn't like this. So enter a value like localhost or the specific IP address or DNS name for your server (usually its just localhost in development envirionments). Save your changes and restart the server. Your Test Console will now work correctly.

VSDB to SSDT Part 2 : SQL Server 2008 Server Project … with SSDT

- by Etienne Giust

With Visual Studio 2012 and the use of SSDT technology, there is only one type of database project : SQL Server Database Project. With Visual Studio 2010, we used to have SQL Server 2008 Server Project which we used to define server-level objects, mostly logins and linked servers. A convenient wizard allowed for creation of this type of projects. It does not exists anymore. Here is how to create an equivalent of the SQL Server 2008 Server Project with Visual Studio 2012: Create a new SQL Server Database Project : it will be created empty Create a new SQL Schema Compare ( SQL menu item > Schema Compare > New Schema Comparison ) As a source, select any database on the SQL server you want to mimic Set the target to be your newly Database Project In the Schema Compare options (cog-like icon), Object Types pane, set the options as below. You might want to tweak those and select only the object types you want. Then, run the comparison, review and select your changes and apply them to the project.

How to Quickly Cut a Clip From a Video File with Avidemux

- by Trevor Bekolay

Whether you’re cutting out the boring parts of your vacation video or getting a hilarious scene for an animated GIF, Avidemux provides a quick and easy way to cut clips from any video file. It’s overkill to use a full-featured video editing program if you just want to cut a few clips from a video file. Even programs that are designed to be small can have confusing interfaces when dealing with video. We’ve found that a great free program, Avidemux, makes the job of cutting clips extremely simple. Note: While the screenshots in this guide are taken from the Windows version, Avidemux runs on all of the major platforms – Windows, Mac OS X and Linux (GTK). Image by Keith Williamson. Cutting Clips from a Video File Open up Avidemux, and load the video file that you want to work with. If you get a prompt like this one: we recommend clicking Yes to use the safer mode. Find the portion of the video that you’d like to isolate. Get as close as you can to the start of the clip you want to cut. Once you find the start of your clip, look at the “Frame Type” of the current frame. You want it to read I; if it isn’t frame type I, then use the single left and right arrow buttons to go forward or backward one frame until you find an appropriate I frame. Once you’ve found the right starting frame, click the button with the A over a red bar. This will set the start of the clip. Advance to where you want your clip to end. Click on the button with a B when you’ve found the appropriate frame. This frame can be of any type. You can now save the clip, either by going to File –> Save –> Save Video… or by pressing Ctrl+S. Give the file a name, and Avidemux will prepare your clip. And that’s it! You should now have a movie file that contains only the portion of the original file that you want.

Pluralsight Meet the Author Podcast on HTML5 Canvas Programming

- by dwahlin

In the latest installment of Pluralsight’s Meet the Author podcast series, Fritz Onion and I talk about my new course, HTML5 Canvas Fundamentals. In the interview I describe different canvas technologies covered throughout the course and a sample application at the end of the course that covers how to build a custom business chart from start to finish. Meet the Author: Dan Wahlin on HTML5 Canvas Fundamentals Transcript [Fritz] Hi. This is Fritz Onion. I’m here today with Dan Wahlin to talk about his new course HTML5 Canvas Fundamentals. Dan founded the Wahlin Group, which you can find at thewahlingroup.com, which specializes in ASP.NET, jQuery, Silverlight, and SharePoint consulting. He’s a Microsoft Regional Director and has been awarded Microsoft’s MVP for ASP.NET, Connected Systems, and Silverlight. Dan is on the INETA Bureau’s — Speaker’s Bureau, speaks at conferences and user groups around the world, and has written several books on .NET. Thanks for talking to me today, Dan. [Dan] Always good to talk with you, Fritz. [Fritz] So this new course of yours, HTML5 Canvas Fundamentals, I have to say that most of the really snazzy demos I’ve seen with HTML5 have involved Canvas, so I thought it would be a good starting point to chat with you about why we decided to create a course dedicated just to Canvas. If you want to kind of give us that perspective. [Dan] Sure. So, you know, there’s quite a bit of material out there on HTML5 in general, and as people that have done a lot with HTML5 are probably aware, a lot of HTML5 is actually JavaScript centric. You know, a lot of people when they first learn it, think it’s tags, but most of it’s actually JavaScript, and it just so happens that the HTML5 Canvas is one of those things. And so it’s not just, you know, a tag you add and it just magically draws all these things. You mentioned there’s a lot of cool things you can do from games to there’s some really cool multimedia applications out there where they integrate video and audio and all kinds of things into the Canvas, to more business scenarios such as charting and things along those lines. So the reason we made a course specifically on it is, a lot of the material out there touches on it but the Canvas is actually a pretty deep topic. You can do some pretty advanced stuff or easy stuff depending on what your application requirements are, and the API itself, you know, there’s over 30 functions just in the Canvas API and then a whole set of properties that actually go with that as well. So it’s a pretty big topic, and that’s why we created a course specifically tailored towards just the Canvas. [Fritz] Right. And let’s — let me just review the outline briefly here for everyone. So you start off with an introduction to getting started with Canvas, drawing with the HTML5 Canvas, then you talk about manipulating pixels, and you finish up with building a custom data chart. So I really like your example flow here. I think it will appeal to even business developers, right. Even if you’re not into HTML5 for the games or the media capabilities, there’s still something here for everyone I think working with the Canvas. Which leads me to another question, which is, where do you see the Canvas fitting in to kind of your day-to-day developer, people that are working business applications and maybe vanilla websites that aren’t doing kind of cutting edge stuff with interactivity with users? Is there a still a place for the Canvas in those scenarios? [Dan] Yeah, definitely. I think a lot of us — and I include myself here — over the last few years, the focus has generally been, especially if you’re, let’s say, a PHP or ASP.NET or Java type of developer, we’re kind of accustomed to working on the server side, and, you know, we kind of relied on Flash or Silverlight or these other plug-ins for the client side stuff when it was kind of fancy, like charts and graphs and things along those lines. With the what I call massive shift of applications, you know, mainly because of mobile, to more of client side, one of the big benefits I think from a maybe corporate standard way of thinking of things, since we do a lot of work with different corporations, is that, number one, rather than having to have the plug-in, which of course isn’t going to work on iPad and some of these other devices out there that are pretty popular, you can now use a built-in technology that all the modern browsers support, and that includes things like Safari on the iPad and iPhone and the Android tablets and things like that with their browsers, and actually render some really sophisticated charts. Whether you do it by scratch or from scratch or, you know, get a third party type of library involved, it’s just JavaScript. So it downloads fast so it’s good from a performance perspective; and when it comes to what you can render, it’s extremely robust. You can do everything from, you know, your basic circles to polygons or polylines to really advanced gradients as well and even provide some interactivity and animations, and that’s some of the stuff I touch upon in the class. In fact, you mentioned the last part of the outline there is building a custom data chart and that’s kind of gears towards more of the, what I’d call enterprise or corporate type developer. [Fritz] Yeah, that makes sense. And it’s, you know, a lot of the demos I’ve seen with HTML5 focus on more the interactivity and kind of game side of things, but the Canvas is such a diverse element within HTML5 that I can see it being applicable pretty much anywhere. So why don’t we talk a little bit about some of the specifics of what you cover? You talk about drawing and then manipulating pixels. You want to kind of give us the different ways of working with the Canvas and what some of those APIs provide for you? [Dan] Sure. So going all the way back to the start of the outline, we actually started off by showing different demonstrations of the Canvas in action, and we show some fun stuff — multimedia apps and games and things like that — and then also some more business scenarios; and then once you see that, hopefully it kinds of piques your interest and you go, oh, wow, this is actually pretty phenomenal what you can do. So then we start you off with, so how to you actually draw things. Now, there are some libraries out there that will draw things like graphs, but if you want to customize those or just build something you have from scratch, you need to know the basics, such as, you know, how do you draw circles and lines and arcs and Bezier curves and all those fancy types of shapes that a given chart may have on it or that a game may have in it for that matter. So we start off by covering what I call the core API functions; how do you, for instance, fill a rectangle or convert that to a square by setting the height and the width; how do you draw arcs or different types of curves and there’s different types supported such as I mentioned Bezier curves or quadratic curves; and then we also talk about how do you integrate text into it. You might have some images already that are just regular bitmap type images that you want to integrate, you can do that with a Canvas. And you can even sync video into the Canvas, which actually opens up some pretty interesting possibilities for both business and I think just general multimedia apps. Once you kind of get those core functions down for the basic shapes that you need to be able to draw on any type of Canvas, then we go a little deeper into what are the pixels that are there to manipulate. And that’s one of the important things to understand about the HTML5 Canvas, scalable vector graphics is another thing you can use now in the modern browsers; it’s vector based. Canvas is pixel based. And so we talk about how to do gradients, how can you do transforms, you know, how do you scale things or rotate things, which is extremely useful for charts ’cause you might have text that, you know, flips up on its side for a y-axis or something like that. And you can even do direct pixel manipulation. So it’s really, really powerful. If you want to get down to the RGBA level, you can do that, and I show how to do that in the course, and then kind of wrap that section up with some animation fundamentals. [Fritz] Great. Yeah, that’s really powerful stuff for programmatically rendering data to clients and responding to user inputs. Look forward to seeing what everyone’s going to come up with building this stuff. So great. That’s — that’s HTML5 Canvas Fundamentals with Dan Wahlin. Thanks very much, Dan. [Dan] Thanks again. I appreciate it.

How to deploy Document Set using CAML in SharePoint2010 solution package

- by ybbest

In my last post, I showed you how to use Document Set using SharePoint UI in the browser. In this post, I’d like to show you how to create the same Document Set using CAML and SharePoint solution package. You can download the complete solution here. 1. Create the Application Number site column using the SharePoint empty element item template in VS2010 <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/"> <Field Type="Text" DisplayName="ApplicationNumber" Required="FALSE" EnforceUniqueValues="FALSE" Indexed="FALSE" MaxLength="255" Group="YBBEST" ID="{916bf3af-5ec1-4441-acd8-88ff62ab1b7e}" Name="ApplicationNumber" ></Field> </Elements> 2. Create the Loan Application Form and Loan Contract Form content types. <?xml version="1.0" encoding="utf-8"?> <Elements xmlns="http://schemas.microsoft.com/sharepoint/">  <ContentType ID="0x0101005dfbf820ce3c49f69c73a00e0e0e53f6" Name="Loan Contract Form" Group="YBBEST" Description="Loan Contract Form" Inherits="TRUE" Version="0"> <FieldRefs> <FieldRef ID="916bf3af-5ec1-4441-acd8-88ff62ab1b7e" Name="ApplicationNumber" DisplayName="ApplicationNumber" /> </FieldRefs> </ContentType>  <ContentType ID="0x010100f3016e3d03454b93bc4d6ab63941c0d2" Name="Loan Application Form" Group="YBBEST" Description="Loan Application Form" Inherits="TRUE" Version="0"> <FieldRefs> <FieldRef ID="916bf3af-5ec1-4441-acd8-88ff62ab1b7e" Name="ApplicationNumber" DisplayName="ApplicationNumber" /> </FieldRefs> </ContentType> </Elements> 3. Create the Loan Application Document Set. 4. Create the Document Set Welcome Page using the SharePoint Module item template. Notes: 1.When creating document set content type , you need to set the Inherits=”FALSE” or remove the Inherits=”TRUE” from the content type definition (default is Inherits=”FALSE”) .

Microsoft, jQuery, and Templating

- by Stephen Walther

About two months ago, John Resig and I met at Café Algiers in Harvard square to discuss how Microsoft can contribute to the jQuery project. Today, Scott Guthrie announced in his second-day MIX keynote that Microsoft is throwing its weight behind jQuery and making it the primary way to develop client-side Ajax applications using Microsoft technologies. What does this announcement mean? It means that Microsoft is shifting its resources to invest in jQuery. Developers on the ASP.NET team are now working full-time to contribute features to the core jQuery library. Furthermore, we are working with other teams at Microsoft to ensure that our technologies work great with jQuery. We are contributing to the open-source jQuery project in the exact same way that any other company or individual from the community can contribute to jQuery. We are writing proposals, submitting the proposals to the jQuery forums, and revising the proposals in response to community feedback. The jQuery team can decide to reject or accept any feature that we propose. Any feature that Microsoft contributes to jQuery will be platform neutral. In other words, Microsoft contributions will benefit PHP and RAILS developers just as much as they benefit ASP.NET developers. Microsoft contributions to jQuery will improve the web for everyone. Contributing Support for Templates to jQuery Core Our first proposal concerns templating. We want to contribute support for templates to jQuery so that JavaScript developers can use jQuery to easily display a set of database records. You can read our templating proposal here: http://wiki.github.com/nje/jquery/jquery-templates-proposal You can download and play with our prototype for templating here: http://github.com/nje/jquery-tmpl The following code illustrates how you can use a template to display a set of products in a bulleted list: <script type="text/javascript"> jQuery(function(){ var products = [ { name: "Product 1", price: 12.99}, { name: "Product 2", price: 9.99}, { name: "Product 3", price: 35.59} ]; $("ul").append("#template", products); }); </script> <script id="template" type="text/html"> <li>{%= name %} - {%= price %}</li> </script> <ul></ul> The template is contained in a SCRIPT element that has a TYPE=”text/html” attribute. Browsers ignore the contents of a SCRIPT element when they don’t understand the content type. Notice that the placeholder {%=...%} is used within the template to indicate where the name and price of a product should appear. The delimiters {%=…%} are used for expressions and the delimiters {%...%} are used for code. Finally, the products are rendered using the template with the call to $(“ul”).append(“#template”, products). The standard jQuery DOM manipulation methods have been modified to support templates. When the page above is rendered, you get the bulleted list displayed in the following figure. Our goal is to keep our proposal for templates as simple as possible. After support for templating has been added to jQuery, plug-in authors can take advantage of templating when building complex data-driven plug-ins such as a DataGrid plug-in. The Ajax Control Toolkit Over 100,000 developers download the Ajax Control Toolkit every month. That’s a mind-boggling number of downloads. We realize that the Ajax Control Toolkit is extremely popular among ASP.NET Web Forms developers and we want to continue to invest in the Ajax Control Toolkit. If you are adding JavaScript interactivity to an ASP.NET Web Forms application, and you don’t want to write JavaScript, then we recommend that you use the server controls in the Ajax Control Toolkit. Using the Ajax Control Toolkit does not require knowledge of JavaScript and the toolkit enables you to build applications with the concepts familiar to ASP.NET Web Forms applications developers. If, however, you are interested in creating client-side interactivity without server controls then we recommend that you use jQuery. We plan to continue to release new versions of the Ajax Control Toolkit every few months. Our goal is to continue to improve the quality of the Ajax Control Toolkit and to make it easier for the community to contribute code, bug fixes, and documentation. The ASP.NET Ajax Library We are moving the ASP.NET Ajax Library into the Ajax Control Toolkit. If you currently use ASP.NET Ajax Library client templates, client data-binding, or the client script loader then you can continue to use these features by downloading the Ajax Control Toolkit. Be aware that our focus with the Ajax Control Toolkit is server-side Ajax. For client-side Ajax, we are shifting our focus to jQuery. For example, if you have been using ASP.NET Ajax Library client templates then we recommend that you shift to using jQuery instead. Conclusion Our plan is to focus on jQuery as the primary technology for building client-side Ajax applications moving forward. We want to adapt Microsoft technologies to work great with jQuery and we want to contribute features to jQuery that will make the web better for everyone. We are very excited to be working with the jQuery core team.

Project Navigation and File Nesting in ASP.NET MVC Projects

- by Rick Strahl

More and more I’m finding myself getting lost in the files in some of my larger Web projects. There’s so much freaking content to deal with – HTML Views, several derived CSS pages, page level CSS, script libraries, application wide scripts and page specific script files etc. etc. Thankfully I use Resharper and the Ctrl-T Go to Anything which autocompletes you to any file, type, member rapidly. Awesome except when I forget – or when I’m not quite sure of the name of what I’m looking for. Project navigation is still important. Sometimes while working on a project I seem to have 30 or more files open and trying to locate another new file to open in the solution often ends up being a mental exercise – “where did I put that thing?” It’s those little hesitations that tend to get in the way of workflow frequently. To make things worse most NuGet packages for client side frameworks and scripts, dump stuff into folders that I generally don’t use. I’ve never been a fan of the ‘Content’ folder in MVC which is just an empty layer that doesn’t serve much of a purpose. It’s usually the first thing I nuke in every MVC project. To me the project root is where the actual content for a site goes – is there really a need to add another folder to force another path into every resource you use? It’s ugly and also inefficient as it adds additional bytes to every resource link you embed into a page. Alternatives I’ve been playing around with different folder layouts recently and found that moving my cheese around has actually made project navigation much easier. In this post I show a couple of things I’ve found useful and maybe you find some of these useful as well or at least get some ideas what can be changed to provide better project flow. The first thing I’ve been doing is add a root Code folder and putting all server code into that. I’m a big fan of treating the Web project root folder as my Web root folder so all content comes from the root without unneeded nesting like the Content folder. By moving all server code out of the root tree (except for Code) the root tree becomes a lot cleaner immediately as you remove Controllers, App_Start, Models etc. and move them underneath Code. Yes this adds another folder level for server code, but it leaves only code related things in one place that’s easier to jump back and forth in. Additionally I find myself doing a lot less with server side code these days, more with client side code so I want the server code separated from that. The root folder itself then serves as the root content folder. Specifically I have the Views folder below it, as well as the Css and Scripts folders which serve to hold only common libraries and global CSS and Scripts code. These days of building SPA style application, I also tend to have an App folder there where I keep my application specific JavaScript files, as well as HTML View templates for client SPA apps like Angular. Here’s an example of what this looks like in a relatively small project: The goal is to keep things that are related together, so I don’t end up jumping around so much in the solution to get to specific project items. The Code folder may irk some of you and hark back to the days of the App_Code folder in non Web-Application projects, but these days I find myself messing with a lot less server side code and much more with client side files – HTML, CSS and JavaScript. Generally I work on a single controller at a time – once that’s open it’s open that’s typically the only server code I work with regularily. Business logic lives in another project altogether, so other than the controller and maybe ViewModels there’s not a lot of code being accessed in the Code folder. So throwing that off the root and isolating seems like an easy win. Nesting Page specific content In a lot of my existing applications that are pure server side MVC application perhaps with some JavaScript associated with them , I tend to have page level javascript and css files. For these types of pages I actually prefer the local files stored in the same folder as the parent view. So typically I have a .css and .js files with the same name as the view in the same folder. This looks something like this: In order for this to work you have to also make a configuration change inside of the /Views/web.config file, as the Views folder is blocked with the BlockViewHandler that prohibits access to content from that folder. It’s easy to fix by changing the path from * to *.cshtml or *.vbhtml so that view retrieval is blocked:<system.webServer> <handlers> <remove name="BlockViewHandler"/> <add name="BlockViewHandler" path="*.cshtml" verb="*" preCondition="integratedMode" type="System.Web.HttpNotFoundHandler" /> </handlers> </system.webServer> With this in place, from inside of your Views you can then reference those same resources like this:<link href="~/Views/Admin/QuizPrognosisItems.css" rel="stylesheet" /> and<script src="~/Views/Admin/QuizPrognosisItems.js"></script> which works fine. JavaScript and CSS files in the Views folder deploy just like the .cshtml files do and can be referenced from this folder as well. Making this happen is not really as straightforward as it should be with just Visual Studio unfortunately, as there’s no easy way to get the file nesting from the VS IDE directly (you have to modify the .csproj file). However, Mads Kristensen has a nice Visual Studio Add-in that provides file nesting via a short cut menu option. Using this you can select each of the ‘child’ files and then nest them under a parent file. In the case above I select the .js and .css files and nest them underneath the .cshtml view. I was even toying with the idea of throwing the controller.cs files into the Views folder, but that’s maybe going a little too far :-) It would work however as Visual Studio doesn’t publish .cs files and the compiler doesn’t care where the files live. There are lots of options and if you think that would make life easier it’s another option to help group related things together. Are there any downside to this? Possibly – if you’re using automated minification/packaging tools like ASP.NET Bundling or Grunt/Gulp with Uglify, it becomes a little harder to group script and css files for minification as you may end up looking in multiple folders instead of a single folder. But – again that’s a one time configuration step that’s easily handled and much less intrusive then constantly having to search for files in your project. Client Side Folders The particular project shown above in the screen shots above is a traditional server side ASP.NET MVC application with most content rendered into server side Razor pages. There’s a fair amount of client side stuff happening on these pages as well – specifically several of these pages are self contained single page Angular applications that deal with 1 or maybe 2 separate views and the layout I’ve shown above really focuses on the server side aspect where there are Razor views with related script and css resources. For applications that are more client centric and have a lot more script and HTML template based content I tend to use the same layout for the server components, but the client side code can often be broken out differently. In SPA type applications I tend to follow the App folder approach where all the application pieces that make the SPA applications end up below the App folder. Here’s what that looks like for me – here this is an AngularJs project: In this case the App folder holds both the application specific js files, and the partial HTML views that get loaded into this single SPA page application. In this particular Angular SPA application that has controllers linked to particular partial views, I prefer to keep the script files that are associated with the views – Angular Js Controllers in this case – with the actual partials. Again I like the proximity of the view with the main code associated with the view, because 90% of the UI application code that gets written is handled between these two files. This approach works well, but only if controllers are fairly closely aligned with the partials. If you have many smaller sub-controllers or lots of directives where the alignment between views and code is more segmented this approach starts falling apart and you’ll probably be better off with separate folders in js folder. Following Angular conventions you’d have controllers/directives/services etc. folders. Please note that I’m not saying any of these ways are right or wrong – this is just what has worked for me and why! Skipping Project Navigation altogether with Resharper I’ve talked a bit about project navigation in the project tree, which is a common way to navigate and which we all use at least some of the time, but if you use a tool like Resharper – which has Ctrl-T to jump to anything, you can quickly navigate with a shortcut key and autocomplete search. Here’s what Resharper’s jump to anything looks like: Resharper’s Goto Anything box lets you type and quick search over files, classes and members of the entire solution which is a very fast and powerful way to find what you’re looking for in your project, by passing the solution explorer altogether. As long as you remember to use (which I sometimes don’t) and you know what you’re looking for it’s by far the quickest way to find things in a project. It’s a shame that this sort of a simple search interface isn’t part of the native Visual Studio IDE. Work how you like to work Ultimately it all comes down to workflow and how you like to work, and what makes *you* more productive. Following pre-defined patterns is great for consistency, as long as they don’t get in the way you work. A lot of the default folder structures in Visual Studio for ASP.NET MVC were defined when things were done differently. These days we’re dealing with a lot more diverse project content than when ASP.NET MVC was originally introduced and project organization definitely is something that can get in the way if it doesn’t fit your workflow. So take a look and see what works well and what might benefit from organizing files differently. As so many things with ASP.NET, as things evolve and tend to get more complex I’ve found that I end up fighting some of the conventions. The good news is that you don’t have to follow the conventions and you have the freedom to do just about anything that works for you. Even though what I’ve shown here diverges from conventions, I don’t think anybody would stumble over these relatively minor changes and not immediately figure out where things live, even in larger projects. But nevertheless think long and hard before breaking those conventions – if there isn’t a good reason to break them or the changes don’t provide improved workflow then it’s not worth it. Break the rules, but only if there’s a quantifiable benefit. You may not agree with how I’ve chosen to divert from the standard project structures in this article, but maybe it gives you some ideas of how you can mix things up to make your existing project flow a little nicer and make it easier to navigate for your environment. © Rick Strahl, West Wind Technologies, 2005-2014Posted in ASP.NET MVC Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

Translate report data export from RUEI into HTML for import into OpenOffice Calc Spreadsheets

- by [email protected]

A common question of users is, How to import the data from the automated data export of Real User Experience Insight (RUEI) into tools for archiving, dashboarding or combination with other sets of data.XML is well-suited for such a translation via the companion Extensible Stylesheet Language Transformations (XSLT). Basically XSLT utilizes XSL, a template on what to read from your input XML data file and where to place it into the target document. The target document can be anything you like, i.e. XHTML, CSV, or even a OpenOffice Spreadsheet, etc. as long as it is a plain text format.XML 2 OpenOffice.org SpreadsheetFor the XSLT to work as an OpenOffice.org Calc Import Filter:How to add an XML Import Filter to OpenOffice CalcStart OpenOffice.org Calc andselect Tools > XML Filter SettingsNew...Fill in the details as follows:Filter name: RUEI Import filterApplication: OpenOffice.org Calc (.ods)Name of file type: Oracle Real User Experience InsightFile extension: xmlSwitch to the transformation tab and enter/select the following leaving the rest untouchedXSLT for import: ruei_report_data_import_filter.xslPlease see at the end of this blog post for a download of the referenced file.Select RUEI Import filter from list and Test XSLTClick on Browse to selectTransform file: export.php.xmlOpenOffice.org Calc will transform and load the XML file you retrieved from RUEI in a human-readable format.You can now select File > Open... and change the filetype to open your RUEI exports directly in OpenOffice.org Calc, just like any other a native Spreadsheet format.Files of type: Oracle Real User Experience Insight (*.xml)File name: export.php.xml XML 2 XHTMLMost XML-powered browsers provides for inherent XSL Transformation capabilities, you only have to reference the XSLT Stylesheet in the head of your XML file.

Internet Protocol Suite: Transition Control Protocol (TCP) vs. User Datagram Protocol (UDP)

How do we communicate over the Internet? How is data transferred from one machine to another? These types of act ivies can only be done by using one of two Internet protocols currently. The collection of Internet Protocol consists of the Transition Control Protocol (TCP) and the User Datagram Protocol (UDP). Both protocols are used to send data between two network end points, however they both have very distinct ways of transporting data from one endpoint to another. If transmission speed and reliability is the primary concern when trying to transfer data between two network endpoints then TCP is the proper choice. When a device attempts to send data to another endpoint using TCP it creates a direct connection between both devices until the transmission has completed. The direct connection between both devices ensures the reliability of the transmission due to the fact that no intermediate devices are needed to transfer the data. Due to the fact that both devices have to continuously poll the connection until transmission has completed increases the resources needed to perform the transmission. An example of this type of direct communication can be seen when a teacher tells a students to do their homework. The teacher is talking directly to the students in order to communicate that the homework needs to be done. Students can then ask questions about the assignment to ensure that they have received the proper instructions for the assignment. UDP is a less resource intensive approach to sending data between to network endpoints. When a device uses UDP to send data across a network, the data is broken up and repackaged with the destination address. The sending device then releases the data packages to the network, but cannot ensure when or if the receiving device will actually get the data. The sending device depends on other devices on the network to forward the data packages to the destination devices in order to complete the transmission. As you can tell this type of transmission is less resource intensive because not connection polling is needed, but should not be used for transmitting data with speed or reliability requirements. This is due to the fact that the sending device can not ensure that the transmission is received. An example of this type of communication can be seen when a teacher tells a student that they would like to speak with their parents. The teacher is relying on the student to complete the transmission to the parents, and the teacher has no guarantee that the student will actually inform the parents about the request. Both TCP and UPD are invaluable when attempting to send data across a network, but depending on the situation one protocol may be better than the other. Before deciding on which protocol to use an evaluation for transmission speed, reliability, latency, and overhead must be completed in order to define the best protocol for the situation.

How do I make good guy attacks only hit bad guys and vice versa?

- by tieTYT

My game has many different type of good guys and many different type of bad guys. They will all be firing projectiles at each other but I don't want any accidental collateral damage to occur for either alignment. So bad guys should not be able to hit/damage other bad guys and good guys should not be able to hit/damage other good guys. The way I'm thinking of solving this is by making it so that the Unit instance (this is javascript, btw), has an alignment property that can be either good or bad. And I'll only let collision happen if the class Attack boolean didAttackCollideWithTarget(target) return attack.source.alignment != target.alignment and collisionDetected(attack.source, target) This is pseudo-code, of course. But I'm asking this question because I get the sense that there might be a much more elegant way to design this besides adding yet another property to my Unit class.

Demystifying Silverlight Dependency Properties

- by dwahlin

I have the opportunity to teach a lot of people about Silverlight (amongst other technologies) and one of the topics that definitely confuses people initially is the concept of dependency properties. I confess that when I first heard about them my initial thought was “Why do we need a specialized type of property?” While you can certainly use standard CLR properties in Silverlight applications, Silverlight relies heavily on dependency properties for just about everything it does behind the scenes. In fact, dependency properties are an essential part of the data binding, template, style and animation functionality available in Silverlight. They simply back standard CLR properties. In this post I wanted to put together a (hopefully) simple explanation of dependency properties and why you should care about them if you’re currently working with Silverlight or looking to move to it. What are Dependency Properties? XAML provides a great way to define layout controls, user input controls, shapes, colors and data binding expressions in a declarative manner. There’s a lot that goes on behind the scenes in order to make XAML work and an important part of that magic is the use of dependency properties. If you want to bind data to a property, style it, animate it or transform it in XAML then the property involved has to be a dependency property to work properly. If you’ve ever positioned a control in a Canvas using Canvas.Left or placed a control in a specific Grid row using Grid.Row then you’ve used an attached property which is a specialized type of dependency property. Dependency properties play a key role in XAML and the overall Silverlight framework. Any property that you bind, style, template, animate or transform must be a dependency property in Silverlight applications. You can programmatically bind values to controls and work with standard CLR properties, but if you want to use the built-in binding expressions available in XAML (one of my favorite features) or the Binding class available through code then dependency properties are a necessity. Dependency properties aren’t needed in every situation, but if you want to customize your application very much you’ll eventually end up needing them. For example, if you create a custom user control and want to expose a property that consumers can use to change the background color, you have to define it as a dependency property if you want bindings, styles and other features to be available for use. Now that the overall purpose of dependency properties has been discussed let’s take a look at how you can create them. Creating Dependency Properties When .NET first came out you had to write backing fields for each property that you defined as shown next: Brush _ScheduleBackground; public Brush ScheduleBackground { get { return _ScheduleBackground; } set { _ScheduleBackground = value; } } Although .NET 2.0 added auto-implemented properties (for example: public Brush ScheduleBackground { get; set; }) where the compiler would automatically generate the backing field used by get and set blocks, the concept is still the same as shown in the above code; a property acts as a wrapper around a field. Silverlight dependency properties replace the _ScheduleBackground field shown in the previous code and act as the backing store for a standard CLR property. The following code shows an example of defining a dependency property named ScheduleBackgroundProperty: public static readonly DependencyProperty ScheduleBackgroundProperty = DependencyProperty.Register("ScheduleBackground", typeof(Brush), typeof(Scheduler), null); Looking through the code the first thing that may stand out is that the definition for ScheduleBackgroundProperty is marked as static and readonly and that the property appears to be of type DependencyProperty. This is a standard pattern that you’ll use when working with dependency properties. You’ll also notice that the property explicitly adds the word “Property” to the name which is another standard you’ll see followed. In addition to defining the property, the code also makes a call to the static DependencyProperty.Register method and passes the name of the property to register (ScheduleBackground in this case) as a string. The type of the property, the type of the class that owns the property and a null value (more on the null value later) are also passed. In this example a class named Scheduler acts as the owner. The code handles registering the property as a dependency property with the call to Register(), but there’s a little more work that has to be done to allow a value to be assigned to and retrieved from the dependency property. The following code shows the complete code that you’ll typically use when creating a dependency property. You can find code snippets that greatly simplify the process of creating dependency properties out on the web. The MVVM Light download available from http://mvvmlight.codeplex.com comes with built-in dependency properties snippets as well. public static readonly DependencyProperty ScheduleBackgroundProperty = DependencyProperty.Register("ScheduleBackground", typeof(Brush), typeof(Scheduler), null); public Brush ScheduleBackground { get { return (Brush)GetValue(ScheduleBackgroundProperty); } set { SetValue(ScheduleBackgroundProperty, value); } } The standard CLR property code shown above should look familiar since it simply wraps the dependency property. However, you’ll notice that the get and set blocks call GetValue and SetValue methods respectively to perform the appropriate operation on the dependency property. GetValue and SetValue are members of the DependencyObject class which is another key component of the Silverlight framework. Silverlight controls and classes (TextBox, UserControl, CompositeTransform, DataGrid, etc.) ultimately derive from DependencyObject in their inheritance hierarchy so that they can support dependency properties. Dependency properties defined in Silverlight controls and other classes tend to follow the pattern of registering the property by calling Register() and then wrapping the dependency property in a standard CLR property (as shown above). They have a standard property that wraps a registered dependency property and allows a value to be assigned and retrieved. If you need to expose a new property on a custom control that supports data binding expressions in XAML then you’ll follow this same pattern. Dependency properties are extremely useful once you understand why they’re needed and how they’re defined. Detecting Changes and Setting Defaults When working with dependency properties there will be times when you want to assign a default value or detect when a property changes so that you can keep the user interface in-sync with the property value. Silverlight’s DependencyProperty.Register() method provides a fourth parameter that accepts a PropertyMetadata object instance. PropertyMetadata can be used to hook a callback method to a dependency property. The callback method is called when the property value changes. PropertyMetadata can also be used to assign a default value to the dependency property. By assigning a value of null for the final parameter passed to Register() you’re telling the property that you don’t care about any changes and don’t have a default value to apply. Here are the different constructor overloads available on the PropertyMetadata class: PropertyMetadata Constructor Overload Description PropertyMetadata(Object) Used to assign a default value to a dependency property. PropertyMetadata(PropertyChangedCallback) Used to assign a property changed callback method. PropertyMetadata(Object, PropertyChangedCalback) Used to assign a default property value and a property changed callback. There are many situations where you need to know when a dependency property changes or where you want to apply a default. Performing either task is easily accomplished by creating a new instance of the PropertyMetadata class and passing the appropriate values to its constructor. The following code shows an enhanced version of the initial dependency property code shown earlier that demonstrates these concepts: public Brush ScheduleBackground { get { return (Brush)GetValue(ScheduleBackgroundProperty); } set { SetValue(ScheduleBackgroundProperty, value); } } public static readonly DependencyProperty ScheduleBackgroundProperty = DependencyProperty.Register("ScheduleBackground", typeof(Brush), typeof(Scheduler), new PropertyMetadata(new SolidColorBrush(Colors.LightGray), ScheduleBackgroundChanged)); private static void ScheduleBackgroundChanged(DependencyObject d, DependencyPropertyChangedEventArgs e) { var scheduler = d as Scheduler; scheduler.Background = e.NewValue as Brush; } The code wires ScheduleBackgroundProperty to a property change callback method named ScheduleBackgroundChanged. What’s interesting is that this callback method is static (as is the dependency property) so it gets passed the instance of the object that owns the property that has changed (otherwise we wouldn’t be able to get to the object instance). In this example the dependency object is cast to a Scheduler object and its Background property is assigned to the new value of the dependency property. The code also handles assigning a default value of LightGray to the dependency property by creating a new instance of a SolidColorBrush. To Sum Up In this post you’ve seen the role of dependency properties and how they can be defined in code. They play a big role in XAML and the overall Silverlight framework. You can think of dependency properties as being replacements for fields that you’d normally use with standard CLR properties. In addition to a discussion on how dependency properties are created, you also saw how to use the PropertyMetadata class to define default dependency property values and hook a dependency property to a callback method. The most important thing to understand with dependency properties (especially if you’re new to Silverlight) is that they’re needed if you want a property to support data binding, animations, transformations and styles properly. Any time you create a property on a custom control or user control that has these types of requirements you’ll want to pick a dependency property over of a standard CLR property with a backing field. There’s more that can be covered with dependency properties including a related property called an attached property….more to come.

Posting from ASP.NET WebForms page to another URL

- by hajan

Few days ago I had a case when I needed to make FORM POST from my ASP.NET WebForms page to an external site URL. More specifically, I was working on implementing Simple Payment System (like Amazon, PayPal, MoneyBookers). The operator asks to make FORM POST request to a given URL in their website, sending parameters together with the post which are computed on my application level (access keys, secret keys, signature, return-URL… etc). So, since we are not allowed nesting another form inside the <form runat=”server”> … </form>, which is required because other controls in my ASPX code work on server-side, I thought to inject the HTML and create FORM with method=”POST”. After making some proof of concept and testing some scenarios, I’ve concluded that I can do this very fast in two ways: Using jQuery to create form on fly with the needed parameters and make submit() Using HttpContext.Current.Response.Write to write the form on server-side (code-behind) and embed JavaScript code that will do the post Both ways seemed fine. 1. Using jQuery to create FORM html code and Submit it. Let’s say we have ‘PAY NOW’ button in our ASPX code: <asp:Button ID="btnPayNow" runat="server" Text="Pay Now" /> Now, if we want to make this button submit a FORM using POST method to another website, the jQuery way should be as follows: <script src="http://ajax.aspnetcdn.com/ajax/jquery/jquery-1.5.1.js" type="text/javascript"></script> <script type="text/javascript"> $(function () { $("#btnPayNow").click(function (event) { event.preventDefault(); //construct htmlForm string var htmlForm = "<form id='myform' method='POST' action='http://www.microsoft.com'>" + "<input type='hidden' id='name' value='hajan' />" + "</form>"; //Submit the form $(htmlForm).appendTo("body").submit(); }); }); </script> Yes, as you see, the code fires on btnPayNow click. It removes the default button behavior, then creates htmlForm string. After that using jQuery we append the form to the body and submit it. Inside the form, you can see I have set the htttp://www.microsoft.com URL, so after clicking the button you should be automatically redirected to the Microsoft website (just for test, of course for Payment I’m using Operator's URL). 2. Using HttpContext.Current.Response.Write to write the form on server-side (code-behind) and embed JavaScript code that will do the post The C# code behind should be something like this: public void btnPayNow_Click(object sender, EventArgs e) { string Url = "http://www.microsoft.com"; string formId = "myForm1"; StringBuilder htmlForm = new StringBuilder(); htmlForm.AppendLine("<html>"); htmlForm.AppendLine(String.Format("<body onload='document.forms[\"{0}\"].submit()'>",formId)); htmlForm.AppendLine(String.Format("<form id='{0}' method='POST' action='{1}'>", formId, Url)); htmlForm.AppendLine("<input type='hidden' id='name' value='hajan' />"); htmlForm.AppendLine("</form>"); htmlForm.AppendLine("</body>"); htmlForm.AppendLine("</html>"); HttpContext.Current.Response.Clear(); HttpContext.Current.Response.Write(htmlForm.ToString()); HttpContext.Current.Response.End(); } So, with this code we create htmlForm string using StringBuilder class and then just write the html to the page using HttpContext.Current.Response.Write. The interesting part here is that we submit the form using JavaScript code: document.forms["myForm1"].submit() This code runs on body load event, which means once the body is loaded the form is automatically submitted. Note: In order to test both solutions, create two applications on your web server and post the form from first to the second website, then get the values in the second website using Request.Form[“input-field-id”] I hope this was useful post for you.

Trabajando el redireccionamiento de usuarios/Working with user redirect methods

- by Jason Ulloa

La protección de las aplicaciones es un elemento que no se puede dejar por fuera cuando se elabora un sistema. Cada parte o elemento de código que protege nuetra aplicación debe ser cuidadosamente seleccionado y elaborado. Una de las cosas comunes con las que nos topamos en asp.net cuando deseamos trabajar con usuarios, es con la necesidad de poder redireccionarlos a los distintos elementos o páginas dependiendo del rol. Pues precisamente eso es lo que haremos, vamos a trabajar con el Web.config de nuestra aplicación y le añadiremos unas pequeñas líneas de código para lograr dar un poco mas de seguridad al sistema y sobre todo lograr el redireccionamiento. Así que veamos como logramos lo deseado: Como bien sabemos el web.config nos permite manejar muchos elementos dentro de asp.net, muchos de ellos relacionados con la seguridad, asi como tambien nos brinda la posibilidad de poder personalizar los elementos para poder adaptarlo a nuestras necesidades. Así que, basandonos en el principio de que podemos personalizar el web.config, entonces crearemos una sección personalizada, que será la que utilicemos para manejar el redireccionamiento: Nuestro primer paso será ir a nuestro web.config y buscamos las siguientes líneas: <configuration> <configSections> </sectionGroup> </sectionGroup> </sectionGroup> Y luego de ellas definiremos una nueva sección <section name="loginRedirectByRole" type="crabit.LoginRedirectByRoleSection" allowLocation="true" allowDefinition="Everywhere" /> El section name corresponde al nombre de nuestra nueva sección Type corresponde al nombre de la clase (que pronto realizaremos) y que será la encargada del Redirect Como estamos trabajando dentro de la seccion de configuración una vez definidad nuestra sección personalizada debemos cerrar esta sección </configSections> Por lo que nuestro web.config debería lucir de la siguiente forma <configuration> <configSections> </sectionGroup> </sectionGroup> </sectionGroup> <section name="loginRedirectByRole" type="crabit.LoginRedirectByRoleSection" allowLocation="true" allowDefinition="Everywhere" /> </configSections> Anteriormente definimos nuestra sección, pero esta sería totalmente inútil sin el Metodo que le da vida. En nuestro caso el metodo loginRedirectByRole, este metodo lo definiremos luego del </configSections> último que cerramos: <loginRedirectByRole> <roleRedirects> <add role="Administrador" url="~/Admin/Default.aspx" /> <add role="User" url="~/User/Default.aspx" /> </roleRedirects> </loginRedirectByRole> Como vemos, dentro de nuestro metodo LoginRedirectByRole tenemos el elemento add role. Este elemento será el que posteriormente le indicará a la aplicación hacia donde irá el usuario cuando realice un login correcto. Así que, veamos un poco esta configuración: add role="Administrador" corresponde al nombre del Role que tenemos definidio, pueden existir tantos elementos add role como tengamos definidos en nuestra aplicación. El elemento URL indica la ruta o página a la que será dirigido un usuario una vez logueado y dentro de la aplicación. Como vemos estamos utilizando el ~ para indicar que es una ruta relativa. Con esto hemos terminado la configuración de nuestro web.config, ahora veamos a fondo el código que se encargará de leer estos elementos y de utilziarlos: Para nuestro ejemplo, crearemos una nueva clase denominada LoginRedirectByRoleSection, recordemos que esta clase es la que llamamos en el elemento TYPE definido en la sección de nuestro web.config. Una vez creada la clase, definiremos algunas propiedades, pero antes de ello le indicaremos a nuestra clase que debe heredar de configurationSection, esto para poder obtener los elementos del web.config. Inherits ConfigurationSection Ahora nuestra primer propiedad <ConfigurationProperty("roleRedirects")> _ Public Property RoleRedirects() As RoleRedirectCollection Get Return DirectCast(Me("roleRedirects"), RoleRedirectCollection) End Get Set(ByVal value As RoleRedirectCollection) Me("roleRedirects") = value End Set End Property End Class Esta propiedad será la encargada de obtener todos los roles que definimos en la metodo personalizado de nuestro web.config Nuestro segundo paso será crear una segunda clase (en la misma clase LoginRedirectByRoleSection) a esta clase la llamaremos RoleRedirectCollection y la heredaremos de ConfigurationElementCollection y definiremos lo siguiente Public Class RoleRedirectCollection Inherits ConfigurationElementCollection Default Public ReadOnly Property Item(ByVal index As Integer) As RoleRedirect Get Return DirectCast(BaseGet(index), RoleRedirect) End Get End Property Default Public ReadOnly Property Item(ByVal key As Object) As RoleRedirect Get Return DirectCast(BaseGet(key), RoleRedirect) End Get End Property Protected Overrides Function CreateNewElement() As ConfigurationElement Return New RoleRedirect() End Function Protected Overrides Function GetElementKey(ByVal element As ConfigurationElement) As Object Return DirectCast(element, RoleRedirect).Role End Function End Class Nuevamente crearemos otra clase esta vez llamada RoleRedirect y en este caso la heredaremos de ConfigurationElement. Nuestra nueva clase debería lucir así: Public Class RoleRedirect Inherits ConfigurationElement <ConfigurationProperty("role", IsRequired:=True)> _ Public Property Role() As String Get Return DirectCast(Me("role"), String) End Get Set(ByVal value As String) Me("role") = value End Set End Property <ConfigurationProperty("url", IsRequired:=True)> _ Public Property Url() As String Get Return DirectCast(Me("url"), String) End Get Set(ByVal value As String) Me("url") = value End Set End Property End Class Una vez que nuestra clase madre esta lista, lo unico que nos queda es un poc de codigo en la pagina de login de nuestro sistema (por supuesto, asumo que estan utilizando los controles de login que por defecto tiene asp.net). Acá definiremos nuestros dos últimos metodos Protected Sub ctllogin_LoggedIn(ByVal sender As Object, ByVal e As System.EventArgs) Handles ctllogin.LoggedIn RedirectLogin(ctllogin.UserName) End Sub El procedimiento loggeding es parte del control login de asp.net y se desencadena en el momento en que el usuario hace loguin correctametne en nuestra aplicación Este evento desencadenará el siguiente procedimiento para redireccionar. Private Sub RedirectLogin(ByVal username As String) Dim roleRedirectSection As crabit.LoginRedirectByRoleSection = DirectCast(ConfigurationManager.GetSection("loginRedirectByRole"), crabit.LoginRedirectByRoleSection) For Each roleRedirect As crabit.RoleRedirect In roleRedirectSection.RoleRedirects If Roles.IsUserInRole(username, roleRedirect.Role) Then Response.Redirect(roleRedirect.Url) End If Next End Sub Con esto, nuestra aplicación debería ser capaz de redireccionar sin problemas y manejar los roles. Además, tambien recordar que nuestro ejemplo se basa en la utilización del esquema de bases de datos que por defecto nos proporcionada asp.net.

Alert visualization recipe: Get out your blender, drop in some sp_send_dbmail, Google Charts API, add your favorite colors and sprinkle with html. Blend till it’s smooth and looks pretty enough to taste.

- by Maria Zakourdaev

I really like database monitoring. My email inbox have a constant flow of different types of alerts coming from our production servers with all kinds of information, sometimes more useful and sometimes less useful. Usually database alerts look really simple, it’s usually a plain text email saying “Prod1 Database data file on Server X is 80% used. You’d better grow it manually before some query triggers the AutoGrowth process”. Imagine you could have received email like the one below. In addition to the alert description it could have also included the the database file growth chart over the past 6 months. Wouldn’t it give you much more information whether the data growth is natural or extreme? That’s truly what data visualization is for. Believe it or not, I have sent the graph below from SQL Server stored procedure without buying any additional data monitoring/visualization tool. Would you like to visualize your database alerts like I do? Then like myself, you’d love the Google Charts. All you need to know is a little HTML and have a mail profile configured on your SQL Server instance regardless of the SQL Server version. First of all, I hope you know that the sp_send_dbmail procedure has a great parameter @body_format = ‘HTML’, which allows us to send rich and colorful messages instead of boring black and white ones. All that we need is to dynamically create HTML code. This is how, for instance, you can create a table and populate it with some data: DECLARE @html varchar(max) SET @html = '<html>' + '<H3><font id="Text" style='color: Green;'>Top Databases: </H3>' + '<table border="1" bordercolor="#3300FF" style='background-color:#DDF8CC' width='70%' cellpadding='3' cellspacing='3'>' + '<tr><font color="Green"><th>Database Name</th><th>Size</th><th>Physical Name</th></tr>' + CAST( (SELECT TOP 10 td = name,'', td = size * 8/1024 ,'', td = physical_name FROM sys.master_files ORDER BY size DESC FOR XML PATH ('tr'),TYPE ) AS VARCHAR(MAX)) + '</table>' EXEC msdb.dbo.sp_send_dbmail @recipients = '[email protected]', @subject ='Top databases', @body = @html, @body_format = 'HTML' This is the result: If you want to add more visualization effects, you can use Google Charts Tools https://google-developers.appspot.com/chart/interactive/docs/index which is a free and rich library of data visualization charts, they’re also easy to populate and embed. There are two versions of the Google Charts Image based charts: https://google-developers.appspot.com/chart/image/docs/gallery/chart_gall This is an old version, it’s officially deprecated although it will be up for a next few years or so. I really enjoy using this one because it can be viewed within the email body. For mobile devices you need to change the “Load remote images” property in your email application configuration. Charts based on JavaScript classes: https://google-developers.appspot.com/chart/interactive/docs/gallery This API is newer, with rich and highly interactive charts, and it’s much more easier to understand and configure. The only downside of it is that they cannot be viewed within the email body. Outlook, Gmail and many other email clients, as part of their security policy, do not run any JavaScript that’s placed within the email body. However, you can still enjoy this API by sending the report as an email attachment. Here is an example of the old version of Google Charts API, sending the same top databases report as in the previous example but instead of a simple table, this script is using a pie chart right from the T-SQL code DECLARE @html varchar(8000) DECLARE @Series varchar(800),@Labels varchar(8000),@Legend varchar(8000); SET @Series = ''; SET @Labels = ''; SET @Legend = ''; SELECT TOP 5 @Series = @Series + CAST(size * 8/1024 as varchar) + ',', @Labels = @Labels +CAST(size * 8/1024 as varchar) + 'MB'+'|', @Legend = @Legend + name + '|' FROM sys.master_files ORDER BY size DESC SELECT @Series = SUBSTRING(@Series,1,LEN(@Series)-1), @Labels = SUBSTRING(@Labels,1,LEN(@Labels)-1), @Legend = SUBSTRING(@Legend,1,LEN(@Legend)-1) SET @html = '<H3><font color="Green"> '+@@ServerName+' top 5 databases : </H3>'+ '<br>'+ '<img src="http://chart.apis.google.com/chart?'+ 'chf=bg,s,DDF8CC&'+ 'cht=p&'+ 'chs=400x200&'+ 'chco=3072F3|7777CC|FF9900|FF0000|4A8C26&'+ 'chd=t:'+@Series+'&'+ 'chl='+@Labels+'&'+ 'chma=0,0,0,0&'+ 'chdl='+@Legend+'&'+ 'chdlp=b"'+ 'alt="'+@@ServerName+' top 5 databases" />' EXEC msdb.dbo.sp_send_dbmail @recipients = '[email protected]', @subject = 'Top databases', @body = @html, @body_format = 'HTML' This is what you get.

In the example below, the sp_send_email procedure uses the parameter @query which will be executed at the time that sp_send_dbemail is executed and the HTML result of this execution will be attached to the email. DECLARE @html varchar(max),@query varchar(max) DECLARE @SeriesDBusers varchar(800); SET @SeriesDBusers = ''; SELECT @SeriesDBusers = @SeriesDBusers + ' ["'+DB_NAME(r.database_id) +'", ' +cast(count(1) as varchar)+'],' FROM sys.dm_exec_requests r GROUP BY DB_NAME(database_id) ORDER BY count(1) desc; SET @SeriesDBusers = SUBSTRING(@SeriesDBusers,1,LEN(@SeriesDBusers)-1) SET @query = ' PRINT '' <html> <head> <script type="text/javascript" src="https://www.google.com/jsapi"></script> <script type="text/javascript"> google.load("visualization", "1", {packages:["corechart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var data = google.visualization.arrayToDataTable([ ["Database Name", "Active users"], '+@SeriesDBusers+' ]); var options = { title: "Active users", pieSliceText: "value" }; var chart = new google.visualization.PieChart(document.getElementById("chart_div")); chart.draw(data, options); }; </script> </head> <body> <table> <tr><td> <div id="chart_div" style='width: 800px; height: 300px;'></div> </td></tr> </table> </body> </html> ''' EXEC msdb.dbo.sp_send_dbmail @recipients = '[email protected]', @subject ='Active users', @body = @html, @body_format = 'HTML', @query = @Query, @attach_query_result_as_file = 1, @query_attachment_filename = 'Results.htm' After opening the email attachment in the browser you are getting this kind of report: In fact, the above is not only for database alerts. It can be used for applicative reports if you need high levels of customization that you cannot achieve using standard methods like SSRS. If you need more information on how to customize the charts, you can try the following: Image Based Charts wizard https://google-developers.appspot.com/chart/image/docs/chart_wizard Live Image Charts Playground https://google-developers.appspot.com/chart/image/docs/chart_playground Image Based Charts Parameters List https://google-developers.appspot.com/chart/image/docs/chart_params Java Script Charts Playground https://code.google.com/apis/ajax/playground/?type=visualization Use the above examples as a starting point for your procedures and I’d be more than happy to hear of your implementations of the above techniques.

Frequent Disconnects ubuntu desktop 12.10 x64 intel 82579V e1000e

- by user112055

I'm having frequent disconnects with my new install of Ubuntu 12.10. I tried updating the kernel driver to the latest intel release to no avail. My expertise is spent. It happens anywhere between 1 min and 10 min. Any ideas? syslog: Dec 1 13:51:39 andromeda kernel: [ 972.188809] audit_printk_skb: 6 callbacks suppressed Dec 1 13:51:39 andromeda kernel: [ 972.188813] type=1701 audit(1354398699.418:199): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188817] type=1701 audit(1354398699.418:200): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188820] type=1701 audit(1354398699.418:201): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188823] type=1701 audit(1354398699.418:202): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.188825] type=1701 audit(1354398699.418:203): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=4 compat=0 ip=0x7f26777d9205 code=0x50000 Dec 1 13:51:39 andromeda kernel: [ 972.331419] type=1701 audit(1354398699.558:204): auid=4294967295 uid=1000 gid=1000 ses=4294967295 pid=6039 comm="chrome" reason="seccomp" sig=0 syscall=2 compat=0 ip=0x7f26777d96b0 code=0x50000 Dec 1 13:53:12 andromeda NetworkManager[1115]: <info> (eth0): carrier now OFF (device state 100, deferring action for 4 seconds) Dec 1 13:53:12 andromeda kernel: [ 1064.894387] e1000e: e1000e: eth0 NIC Link is Down Dec 1 13:53:16 andromeda NetworkManager[1115]: <info> (eth0): device state change: activated -> unavailable (reason 'carrier-changed') [100 20 40] Dec 1 13:53:16 andromeda NetworkManager[1115]: <info> (eth0): deactivating device (reason 'carrier-changed') [40] Dec 1 13:53:16 andromeda NetworkManager[1115]: <info> (eth0): canceled DHCP transaction, DHCP client pid 5946 Dec 1 13:53:16 andromeda avahi-daemon[890]: Withdrawing address record for fe80::ea40:f2ff:fee2:4d86 on eth0.
