  • Speaking at SQL Saturday 61 in Washington DC

    - by AllenMWhite
    The organizers of SQL Saturday #61 in DC (actually Reston, VA) created an Advanced DBA/Dev track for their event, which I think is cool. Both of the presentations I'll be doing there on Saturday are in that track. (In fact, they're the first two sessions of the day.) The first, Automate Policy-Based Management using PowerShell will walk through the basics of Policy-Based Management, and then show you how to build PowerShell scripts to create and evaluate your policies. The second, Gather SQL Server...(read more)

  • Using the jQuery UI Library in a MVC 3 Application to Build a Dialog Form

    - by ChrisD
    Using a simulated dialog window is a nice way to handle inline data editing. The jQuery UI has a UI widget for a dialog window that makes it easy to get up and running with it in your application. With the release of ASP.NET MVC 3, Microsoft included the jQuery UI scripts and files in the MVC 3 project templates for Visual Studio. With the release of the MVC 3 Tools Update, Microsoft implemented the inclusion of those with NuGet as packages. That means we can get up and running using the latest version of the jQuery UI with minimal effort. To the code! Another that might interested you about JQuery Mobile and ASP.NET MVC 3 with C#. If you are starting with a new MVC 3 application and have the Tools Update then you are a NuGet update and a <link> and <script> tag away from adding the jQuery UI to your project. If you are using an existing MVC project you can still get the jQuery UI library added to your project via NuGet and then add the link and script tags. Assuming that you have pulled down the latest version (at the time of this publish it was 1.8.13) you can add the following link and script tags to your <head> tag: < link href = "@Url.Content(" ~ / Content / themes / base / jquery . ui . all . css ")" rel = "Stylesheet" type = "text/css" /> < script src = "@Url.Content(" ~ / Scripts / jquery-ui-1 . 8 . 13 . min . js ")" type = "text/javascript" ></ script > The jQuery UI library relies upon the CSS scripts and some image files to handle rendering of its widgets (you can choose a different theme or role your own if you like). Adding these to the stock _Layout.cshtml file results in the following markup: <!DOCTYPE html> < html > < head >     < meta charset = "utf-8" />     < title > @ViewBag.Title </ title >     < link href = "@Url.Content(" ~ / Content / Site . css ")" rel = "stylesheet" type = "text/css" />     <link href="@Url.Content("~/Content/themes/base/jquery.ui.all.css")" rel="Stylesheet" type="text/css" />     <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>     <script src="@Url.Content("~/Scripts/modernizr-1.7.min . js ")" type = "text/javascript" ></ script >     < script src = "@Url.Content(" ~ / Scripts / jquery-ui-1 . 8 . 13 . min . js ")" type = "text/javascript" ></ script > </ head > < body >     @RenderBody() </ body > </ html > Our example will involve building a list of notes with an id, title and description. Each note can be edited and new notes can be added. The user will never have to leave the single page of notes to manage the note data. The add and edit forms will be delivered in a jQuery UI dialog widget and the note list content will get reloaded via an AJAX call after each change to the list. To begin, we need to craft a model and a data management class. We will do this so we can simulate data storage and get a feel for the workflow of the user experience. The first class named Note will have properties to represent our data model. namespace Website . Models {     public class Note     {         public int Id { get ; set ; }         public string Title { get ; set ; }         public string Body { get ; set ; }     } } The second class named NoteManager will be used to set up our simulated data storage and provide methods for querying and updating the data. We will take a look at the class content as a whole and then walk through each method after. using System . Collections . ObjectModel ; using System . Linq ; using System . Web ; namespace Website . Models {     public class NoteManager     {         public Collection < Note > Notes         {             get             {                 if ( HttpRuntime . Cache [ "Notes" ] == null )                     this . loadInitialData ();                 return ( Collection < Note >) HttpRuntime . Cache [ "Notes" ];             }         }         private void loadInitialData ()         {             var notes = new Collection < Note >();             notes . Add ( new Note                           {                               Id = 1 ,                               Title = "Set DVR for Sunday" ,                               Body = "Don't forget to record Game of Thrones!"                           });             notes . Add ( new Note                           {                               Id = 2 ,                               Title = "Read MVC article" ,                               Body = "Check out the new iwantmymvc.com post"                           });             notes . Add ( new Note                           {                               Id = 3 ,                               Title = "Pick up kid" ,                               Body = "Daughter out of school at 1:30pm on Thursday. Don't forget!"                           });             notes . Add ( new Note                           {                               Id = 4 ,                               Title = "Paint" ,                               Body = "Finish the 2nd coat in the bathroom"                           });             HttpRuntime . Cache [ "Notes" ] = notes ;         }         public Collection < Note > GetAll ()         {             return Notes ;         }         public Note GetById ( int id )         {             return Notes . Where ( i => i . Id == id ). FirstOrDefault ();         }         public int Save ( Note item )         {             if ( item . Id <= 0 )                 return saveAsNew ( item );             var existingNote = Notes . Where ( i => i . Id == item . Id ). FirstOrDefault ();             existingNote . Title = item . Title ;             existingNote . Body = item . Body ;             return existingNote . Id ;         }         private int saveAsNew ( Note item )         {             item . Id = Notes . Count + 1 ;             Notes . Add ( item );             return item . Id ;         }     } } The class has a property named Notes that is read only and handles instantiating a collection of Note objects in the runtime cache if it doesn't exist, and then returns the collection from the cache. This property is there to give us a simulated storage so that we didn't have to add a full blown database (beyond the scope of this post). The private method loadInitialData handles pre-filling the collection of Note objects with some initial data and stuffs them into the cache. Both of these chunks of code would be refactored out with a move to a real means of data storage. The GetAll and GetById methods access our simulated data storage to return all of our notes or a specific note by id. The Save method takes in a Note object, checks to see if it has an Id less than or equal to zero (we assume that an Id that is not greater than zero represents a note that is new) and if so, calls the private method saveAsNew . If the Note item sent in has an Id , the code finds that Note in the simulated storage, updates the Title and Description , and returns the Id value. The saveAsNew method sets the Id , adds it to the simulated storage, and returns the Id value. The increment of the Id is simulated here by getting the current count of the note collection and adding 1 to it. The setting of the Id is the only other chunk of code that would be refactored out when moving to a different data storage approach. With our model and data manager code in place we can turn our attention to the controller and views. We can do all of our work in a single controller. If we use a HomeController , we can add an action method named Index that will return our main view. An action method named List will get all of our Note objects from our manager and return a partial view. We will use some jQuery to make an AJAX call to that action method and update our main view with the partial view content returned. Since the jQuery AJAX call will cache the call to the content in Internet Explorer by default (a setting in jQuery), we will decorate the List, Create and Edit action methods with the OutputCache attribute and a duration of 0. This will send the no-cache flag back in the header of the content to the browser and jQuery will pick that up and not cache the AJAX call. The Create action method instantiates a new Note model object and returns a partial view, specifying the NoteForm.cshtml view file and passing in the model. The NoteForm view is used for the add and edit functionality. The Edit action method takes in the Id of the note to be edited, loads the Note model object based on that Id , and does the same return of the partial view as the Create method. The Save method takes in the posted Note object and sends it to the manager to save. It is decorated with the HttpPost attribute to ensure that it will only be available via a POST. It returns a Json object with a property named Success that can be used by the UX to verify everything went well (we won't use that in our example). Both the add and edit actions in the UX will post to the Save action method, allowing us to reduce the amount of unique jQuery we need to write in our view. The contents of the HomeController.cs file: using System . Web . Mvc ; using Website . Models ; namespace Website . Controllers {     public class HomeController : Controller     {         public ActionResult Index ()         {             return View ();         }         [ OutputCache ( Duration = 0 )]         public ActionResult List ()         {             var manager = new NoteManager ();             var model = manager . GetAll ();             return PartialView ( model );         }         [ OutputCache ( Duration = 0 )]         public ActionResult Create ()         {             var model = new Note ();             return PartialView ( "NoteForm" , model );         }         [ OutputCache ( Duration = 0 )]         public ActionResult Edit ( int id )         {             var manager = new NoteManager ();             var model = manager . GetById ( id );             return PartialView ( "NoteForm" , model );         }         [ HttpPost ]         public JsonResult Save ( Note note )         {             var manager = new NoteManager ();             var noteId = manager . Save ( note );             return Json ( new { Success = noteId > 0 });         }     } } The view for the note form, NoteForm.cshtml , looks like so: @model Website . Models . Note @using ( Html . BeginForm ( "Save" , "Home" , FormMethod . Post , new { id = "NoteForm" })) { @Html . Hidden ( "Id" ) < label class = "Title" >     < span > Title < /span><br / >     @Html . TextBox ( "Title" ) < /label> <label class="Body">     <span>Body</ span >< br />     @Html . TextArea ( "Body" ) < /label> } It is a strongly typed view for our Note model class. We give the <form> element an id attribute so that we can reference it via jQuery. The <label> and <span> tags give our UX some structure that we can style with some CSS. The List.cshtml view is used to render out a <ul> element with all of our notes. @model IEnumerable < Website . Models . Note > < ul class = "NotesList" >     @foreach ( var note in Model )     {     < li >         @note . Title < br />         @note . Body < br />         < span class = "EditLink ButtonLink" noteid = "@note.Id" > Edit < /span>     </ li >     } < /ul> This view is strongly typed as well. It includes a <span> tag that we will use as an edit button. We add a custom attribute named noteid to the <span> tag that we can use in our jQuery to identify the Id of the note object we want to edit. The view, Index.cshtml , contains a bit of html block structure and all of our jQuery logic code. @ {     ViewBag . Title = "Index" ; } < h2 > Notes < /h2> <div id="NoteListBlock"></ div > < span class = "AddLink ButtonLink" > Add New Note < /span> <div id="NoteDialog" title="" class="Hidden"></ div > < script type = "text/javascript" >     $ ( function () {         $ ( "#NoteDialog" ). dialog ({             autoOpen : false , width : 400 , height : 330 , modal : true ,             buttons : {                 "Save" : function () {                     $ . post ( "/Home/Save" ,                         $ ( "#NoteForm" ). serialize (),                         function () {                             $ ( "#NoteDialog" ). dialog ( "close" );                             LoadList ();                         });                 },                 Cancel : function () { $ ( this ). dialog ( "close" ); }             }         });         $ ( ".EditLink" ). live ( "click" , function () {             var id = $ ( this ). attr ( "noteid" );             $ ( "#NoteDialog" ). html ( "" )                 . dialog ( "option" , "title" , "Edit Note" )                 . load ( "/Home/Edit/" + id , function () { $ ( "#NoteDialog" ). dialog ( "open" ); });         });         $ ( ".AddLink" ). click ( function () {             $ ( "#NoteDialog" ). html ( "" )                 . dialog ( "option" , "title" , "Add Note" )                 . load ( "/Home/Create" , function () { $ ( "#NoteDialog" ). dialog ( "open" ); });         });         LoadList ();     });     function LoadList () {         $ ( "#NoteListBlock" ). load ( "/Home/List" );     } < /script> The <div> tag with the id attribute of "NoteListBlock" is used as a container target for the load of the partial view content of our List action method. It starts out empty and will get loaded with content via jQuery once the DOM is loaded. The <div> tag with the id attribute of "NoteDialog" is the element for our dialog widget. The jQuery UI library will use the title attribute for the text in the dialog widget top header bar. We start out with it empty here and will dynamically change the text via jQuery based on the request to either add or edit a note. This <div> tag is given a CSS class named "Hidden" that will set the display:none style on the element. Since our call to the jQuery UI method to make the element a dialog widget will occur in the jQuery document ready code block, the end user will see the <div> element rendered in their browser as the page renders and then it will hide after that jQuery call. Adding the display:hidden to the <div> element via CSS will ensure that it is never rendered until the user triggers the request to open the dialog. The jQuery document load block contains the setup for the dialog node, click event bindings for the edit and add links, and a call to a JavaScript function called LoadList that handles the AJAX call to the List action method. The .dialog() method is called on the "NoteDialog" <div> element and the options are set for the dialog widget. The buttons option defines 2 buttons and their click actions. The first is the "Save" button (the text in quotations is used as the text for the button) that will do an AJAX post to our Save action method and send the serialized form data from the note form (targeted with the id attribute "NoteForm"). Upon completion it will close the dialog widget and call the LoadList to update the UX without a redirect. The "Cancel" button simply closes the dialog widget. The .live() method handles binding a function to the "click" event on all elements with the CSS class named EditLink . We use the .live() method because it will catch and bind our function to elements even as the DOM changes. Since we will be constantly changing the note list as we add and edit we want to ensure that the edit links get wired up with click events. The function for the click event on the edit links gets the noteid attribute and stores it in a local variable. Then it clears out the HTML in the dialog element (to ensure a fresh start), calls the .dialog() method and sets the "title" option (this sets the title attribute value), and then calls the .load() AJAX method to hit our Edit action method and inject the returned content into the "NoteDialog" <div> element. Once the .load() method is complete it opens the dialog widget. The click event binding for the add link is similar to the edit, only we don't need to get the id value and we load the Create action method. This binding is done via the .click() method because it will only be bound on the initial load of the page. The add button will always exist. Finally, we toss in some CSS in the Content/Site.css file to style our form and the add/edit links. . ButtonLink { color : Blue ; cursor : pointer ; } . ButtonLink : hover { text - decoration : underline ; } . Hidden { display : none ; } #NoteForm label { display:block; margin-bottom:6px; } #NoteForm label > span { font-weight:bold; } #NoteForm input[type=text] { width:350px; } #NoteForm textarea { width:350px; height:80px; } With all of our code in place we can do an F5 and see our list of notes: If we click on an edit link we will get the dialog widget with the correct note data loaded: And if we click on the add new note link we will get the dialog widget with the empty form: The end result of our solution tree for our sample:

  • Planning for Disaster

    There is a certain paradox in being advised to expect the unexpected, but the DBA must plan and prepare in advance to protect their organisation's data assets in the event of an unexpected crisis, and return them to normal operating conditions. To minimise downtime in such circumstances should be the aim of every effective DBA. To plan for recovery, It pays to have the mindset of a pessimist.

  • Pack of resources in one big file with XNA

    - by Cristian
    Is it possible to pack all the little .xnb files into one big file? Given the level of abstraction of the XNA Framework I though this would come out of the box but I can't find any well integrated solution. So far the best candidate is XnaZip but in addition to having to compile the resources in a post-build event, and a little trouble porting the game to XBOX I have to rename all the references to resources I have already implemented.

  • StreamInsight 1.0 Released

    - by Roman Schindlauer
    One piece in the set of products offered in SQL Server 2008 R2 that has generated a lot of buzz and interest during its CTP phase is StreamInsight, Microsoft’s platform for Complex Event Processing. Microsoft’s information platform vision provides enterprises with a “complete approach” to managing information assets, enabling all businesses to gain strategic value from information from the desktop to the datacenter to the cloud. And StreamInsight V1 is one essential piece in this spectrum. After more than a year of blood, sweat, tears, and insane amounts of coffee we are proud to release the first version of our Complex Event Processing Framework.   Those of you who have been following our Community Technology Previews (CTPs) throughout last year have already had the possibility to familiarize themselves with the product. Early feedback was not only incredibly positive, but also very constructive and strongly influenced the final feature set. Four notable increments over our last public CTP are: Count windows Non-occurrence detection (Anti-Join) Dynamic query composition at runtime Synchronize time across input streams Additionally, many smaller issues and bugs were addressed. A few APIs slightly changed with respect to the November CTP, but porting your application to RTM should not require a lot of effort.   Here are the (english) bits - choosing the evaluation license during setup lets you already play with this version. Before you install, make sure to uninstall any previous CTP version:   StreamInsight X86StreamInsight X64   Within a few days, we will update our product page and add download links and instructions there as well.   The StreamInsight documentation is provided through a help file as part of the installation as well as through Books Online on MSDN. We also invite you to visit the StreamInsight Blog and the StreamInsight Forum, which is a great place to discuss questions and issues with the community and the development team.   Regards,Roman Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • Why you need to learn async in .NET

    - by PSteele
    I had an opportunity to teach a quick class yesterday about what’s new in .NET 4.0.  One of the topics was the TPL (Task Parallel Library) and how it can make async programming easier.  I also stressed that this is the direction Microsoft is going with for C# 5.0 and learning the TPL will greatly benefit their understanding of the new async stuff.  We had a little time left over and I was able to show some code that uses the Async CTP to accomplish some stuff, but it wasn’t a simple demo that you could jump in to and understand so I thought I’d thrown one together and put it in a blog post. The entire solution file with all of the sample projects is located here. A Simple Example Let’s start with a super-simple example (WindowsApplication01 in the solution). I’ve got a form that displays a label and a button.  When the user clicks the button, I want to start displaying the current time for 15 seconds and then stop. What I’d like to write is this: lblTime.ForeColor = Color.Red; for (var x = 0; x < 15; x++) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); Thread.Sleep(1000); } lblTime.ForeColor = SystemColors.ControlText; (Note that I also changed the label’s color while counting – not quite an ILM-level effect, but it adds something to the demo!) As I’m sure most of my readers are aware, you can’t write WinForms code this way.  WinForms apps, by default, only have one thread running and it’s main job is to process messages from the windows message pump (for a more thorough explanation, see my Visual Studio Magazine article on multithreading in WinForms).  If you put a Thread.Sleep in the middle of that code, your UI will be locked up and unresponsive for those 15 seconds.  Not a good UX and something that needs to be fixed.  Sure, I could throw an “Application.DoEvents()” in there, but that’s hacky. The Windows Timer Then I think, “I can solve that.  I’ll use the Windows Timer to handle the timing in the background and simply notify me when the time has changed”.  Let’s see how I could accomplish this with a Windows timer (WindowsApplication02 in the solution): public partial class Form1 : Form { private readonly Timer clockTimer; private int counter;   public Form1() { InitializeComponent(); clockTimer = new Timer {Interval = 1000}; clockTimer.Tick += UpdateLabel; }   private void UpdateLabel(object sender, EventArgs e) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); counter++; if (counter == 15) { clockTimer.Enabled = false; lblTime.ForeColor = SystemColors.ControlText; } }   private void cmdStart_Click(object sender, EventArgs e) { lblTime.ForeColor = Color.Red; counter = 0; clockTimer.Start(); } } Holy cow – things got pretty complicated here.  I use the timer to fire off a Tick event every second.  Inside there, I can update the label.  Granted, I can’t use a simple for/loop and have to maintain a global counter for the number of iterations.  And my “end” code (when the loop is finished) is now buried inside the bottom of the Tick event (inside an “if” statement).  I do, however, get a responsive application that doesn’t hang or stop repainting while the 15 seconds are ticking away. But doesn’t .NET have something that makes background processing easier? The BackgroundWorker Next I try .NET’s BackgroundWorker component – it’s specifically designed to do processing in a background thread (leaving the UI thread free to process the windows message pump) and allows updates to be performed on the main UI thread (WindowsApplication03 in the solution): public partial class Form1 : Form { private readonly BackgroundWorker worker;   public Form1() { InitializeComponent(); worker = new BackgroundWorker {WorkerReportsProgress = true}; worker.DoWork += StartUpdating; worker.ProgressChanged += UpdateLabel; worker.RunWorkerCompleted += ResetLabelColor; }   private void StartUpdating(object sender, DoWorkEventArgs e) { var workerObject = (BackgroundWorker) sender; for (int x = 0; x < 15; x++) { workerObject.ReportProgress(0); Thread.Sleep(1000); } }   private void UpdateLabel(object sender, ProgressChangedEventArgs e) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); }   private void ResetLabelColor(object sender, RunWorkerCompletedEventArgs e) { lblTime.ForeColor = SystemColors.ControlText; }   private void cmdStart_Click(object sender, EventArgs e) { lblTime.ForeColor = Color.Red; worker.RunWorkerAsync(); } } Well, this got a little better (I think).  At least I now have my simple for/next loop back.  Unfortunately, I’m still dealing with event handlers spread throughout my code to co-ordinate all of this stuff in the right order. Time to look into the future. The async way Using the Async CTP, I can go back to much simpler code (WindowsApplication04 in the solution): private async void cmdStart_Click(object sender, EventArgs e) { lblTime.ForeColor = Color.Red; for (var x = 0; x < 15; x++) { lblTime.Text = DateTime.Now.ToString("HH:mm:ss"); await TaskEx.Delay(1000); } lblTime.ForeColor = SystemColors.ControlText; } This code will run just like the Timer or BackgroundWorker versions – fully responsive during the updates – yet is way easier to implement.  In fact, it’s almost a line-for-line copy of the original version of this code.  All of the async plumbing is handled by the compiler and the framework.  My code goes back to representing the “what” of what I want to do, not the “how”. I urge you to download the Async CTP.  All you need is .NET 4.0 and Visual Studio 2010 sp1 – no need to set up a virtual machine with the VS2011 beta (unless, of course, you want to dive right in to the C# 5.0 stuff!).  Starting playing around with this today and see how much easier it will be in the future to write async-enabled applications.

  • Process Rules!

    - by Ajay Khanna
    One of the key components of a process is “Business Rule”. Business rule takes many forms inside your process definition and in a way is a manifestation of your company’s business policy. Business rules inside the process are used for policy enforcement, governance, decision management, operations efficiency etc. Following are some basic types of rules that can be a part of your process. 1. Process conditions:  These are defined as the process gateways that determine a path process will take depending on the process parameters. For Example, if discount >10% go to approval path : if discount < 10% auto-approve order. 2. Data rules: These business rules are defined as facts in decision table or knowledge base. The process captures all required parameters and submits those to RETE based rules engine. Rules engine processes the data and returns the result back. For example, rules determining your insurance eligibility. 3. Event rules: Here the system is monitoring the various events and events patterns that are emerging inside the process or external to the process. You can define actions or alerts to be triggered when a certain pattern of events emerges over a specified time period. Such types of rules need Complex Event Processing and are used in applications like Credit Card Fraud detection or Utility Demand Response. 4. User Interface Rules: In order to add dynamic behavior to UI or to keep users from making mistakes and enforcing policy, another mechanism available is UI rules. They are evaluated as the end user is filling out the web forms. These may include enabling and disabling of UI as per business policy. An example could be, if the age of a user is less than 13 years, disable credit card field and enable parental approval required checkbox. Your process may include many of such rule types. Oracle OpenWorld provides a unique opportunity to listen to Oracle Business Process Management Experts and Customers.  We will discuss business rules during various sessions in Oracle OpenWorld. Two of the sessions specifically focused on business rules are listed below: Accelerating an Implementation of Complex Worldwide Business Approval Rules Wednesday, Oct 3, 10:15 AM Moscone South – 305 Oracle Business Rules Use Cases Design and Testing Wednesday, Oct 3, 3:30 PM Marriott Marquis - Golden Gate C3   Oracle Business Process Management Track covers a variety of topics, and speakers covering technology, methodology and best practices.

  • My program at #MIX10

    - by Laurent Bugnion
    Getting ready to fly to Vegas and MIX10 is really an exciting time! It is also a very busy time, because we are working on a few projects that will be shown on stage, I have my presentation to prepare, and of course as always the book… though these days it has been a bit on the back burner to be honest ;) I arrive in Vegas on Sunday evening around 10PM, so I won’t be able to make it to the traditional IdentityMine dinner this year. I am sure it will be fun nonetheless! My session: Understanding the MVVM pattern http://live.visitmix.com/MIX10/Sessions/EX14 My session is scheduled on the first day, which is awesome, so I am crossing my fingers and hoping that the MIX team doesn’t change it at the last minute… The session will take place on Monday, the 15th of March, 2PM, Room Lagoon F Important: remember that the USA are moving to Summer time on Sunday, so don’t forget to adjust your watches!! Ask the Experts On Monday evening, I will attend the Ask the Experts event, which is taking place between 5Pm and 6:30PM in the main meal hall. This will be a great occasion to grab a beer and talk about code. The Commons MIX has a great place called the Commons, a great location to chill between sessions, and meet tons of interesting people. I love the Commons and plan to spend a lot of time there to meet as many people as I can. Parties I was invited to a few parties, and will do my best to avoid conflicts :) I plan to be at the following events: Silverlight Mixers on Monday evening Insiders MIX party on Tuesday Silverlight partner happy hour on Tuesday too This is a lot of fun, but at the same time we all know that the best value of a conference is to meet people face to face. This is just the right occasion.  And on Thursday… On Thursday I will be attending a Silverlight event at the Luxor. It will be a very busy day, perfect way to end the conference. I fly back home on Friday morning, but due to a long stop in Washington DC (where I intend to go downtown and take pictures… except if the weather is bad, in which case I will probably go to the museum of flight), I will reach home only on Sunday. Getting hold of me The best way to reach me during MIX is to send me a message on Twitter. I will regularly tweet my location at the conference, so make sure to come and meet me. I am eager to make new friends, to talk about the fantastic jobs we did in WPF and Silverlight over the past year and hear your war stories! http://www.twitter.com/lbugnion   Laurent Bugnion (GalaSoft) Subscribe | Twitter | Facebook | Flickr | LinkedIn

  • Web.NET: A Brief Retrospective

    - by Chris Massey
    It’s been several weeks since I had the pleasure of visiting Milan, and joining 150 enthusiastic web developers for a day of server-side frameworks and JavaScript. Lucky for me, I keep good notes. Overall the day went smoothly, with some solid logistics and very attentiveorganizerss, and an impressively diverse audience drawn by the fact that the event was ambitiously run in English. This was great in that it drew a truly pan-European audience (11 countries were represented on the day, and at least 1 visa had to be procured to get someone there!) It was trouble because, in some cases, it pushed speakers outside their comfort zone. Thankfully, despite a slightly rocky start, every session I attended was very well presented, and the consensus on the day was that the speakers were excellent. While I felt that a lot of the speakers had more that they wanted to cover, the topics were well-chosen, every room constantly had a stack of people in it, and all the sessions were pleasingly focused on code & demos. For all that the language barriers occasionally made networking a little challenging,organizerss Simone & Ugo nailed the logistics. Registration was slick, lunch was plentiful, and session management was great. The very generous Rui was kind enough to showcase a short video about Glimpse in his session, which seemed to go down well (Although the audio in the rooms was a little under-powered). Because I think you might need a mid-week chuckle, here are some out-takes.: And lets not forget the Hackathon. The idea was what having just learned about a stack of interesting technologies, attendees could spend an evening (fuelled by pizza and some good Github beer) hacking something together using them. Unfortunately, after a (great)10-hour day, and in many cases facing international travel in the morning, many of the attendees headed straight for their hotel rooms. This idea could work so beautifully, and I’m excited to see how it pans out in 2013. On top of the slick sessions, getting to finally meet Ugo and Simone in the flesh as a pleasure, as was the serendipitous introduction to the most excellent Rui. They’re all fantastic guys who are passionate about the web, and I’m looking forward to finding opportunities to work with them. Simone & Ugo put on a great event, and I’m excited to see what they do next year.

  • Probation is Over: PASS Board Year 1, Q2

    - by Denise McInerney
    Though it's not always official every job begins with a probation period. You start out with lots of questions and every day you find out how much more you have to learn. Usually after a few months you discover that you can actually answer some questions and have at least an idea of what you are supposed to be doing. Now at the end of my second quarter on the "job" of serving on the PASS Board I have reached that point. My probation period is over. The last three months were busy for the entire Board with the budget process, an in-person meeting and moving forward with PASS Global Growth plans. I had also set a specific goal for myself for my 2nd quarter: to see the Board to adopt a Code of Conduct for the PASS Summit. Code of Conduct When I ran for the Board I included my desire to see PASS establish a code of conduct in my campaign platform.  I was motivated to do this for a few reasons. Other technical conferences have had incidents of harassment. Most of these did not have a policy in place prior to having a problem, though several conference organizers have since adopted anti-harassment policies or codes of conduct. I felt it would be in PASS' interest to establish a policy so we would be prepared should there be an incident.   "This is Community" Adopting a code of conduct would reinforce our community orientation and send a message about the positive character of the Summit. PASS is a leader among technical organizations for its promotion and support of women. Adopting a code of conduct would further demonstrate our leadership in this area. After researching similar polices from other organizations I published a first draft in April. I solicited feedback from the Board, HQ staff and some PASS members. Incorporating that feedback I presented version 4 at the May Board meeting, where we had a good discussion. You can read the meeting minutes for details. I incorporated points from  the Board discussion as well as feedback from a legal review to produce a final version which has been submitted to the Board. It will be discussed at the Board meeting July 12. You can read the full text at the end of this post. Virtual Chapters In the first quarter we started ramping up marketing support for the Virtual Chapters. Since then each edition of the Connector has highlighted a different VC to help get out the message about the variety of eductional opporutnities that are offered. These VC profiles will continue in the coming months. I was very pleased to welcome the new DBA Fundamentals VC which is geared toward new DBAs, people who are considering entering the field and those transitioning from a different IT role. Thanks to the contributions of Erin Stellato, Michelle Nalliah and Karla Landrum we published a "Virtual Chapter Guidebook". This document includes great advice on how to build and promote a VC. It's also a reference for how things work, from budgets to webinar hosting. I think this document will be extremely valuable to all our VC leaders and am grateful to those who put it together. Board Meeting/SQL Rally The Board met in May in Dallas. Among the items discussed were Global Growth, the budget, future events and the upcoming elections. We covered a lot of ground in two days and I will again refer you to the meeting minutes for details. The meeting schedule allowed us to participate in the SQL Rally networking events and one full day of the conference. I enjoyed having the opportunity to meet and talk with many PASS members. And my hat is off to the SQL Rally organizers who put on an outstanding event. Global Growth PASS has undertaken a major intitiative to reach and engage SQL Server professionals around the world. This Global Growth plan is ambitious and will have a significant impact on the strategic direction of the organization. We have been reaching out to the community for feedback, including hosting Twitter chats and live Town Hall meetings. I co-hosted two of these events and appreciated hearing the different perspectives of the people who participated If you have not done so I encourage you to read about the Global Growth vision and proposed governance changes  and submit your feedback. FY13 Budget July 1 is the beginning of PASS' fiscal year, which makes the end of June the deadline for approving a budget. Each director submits a budget for his or her portfolio. For the Virtual Chapter portfolio I focused on how we can allocate resources to grow the VCs. Budgeting is a give-and-take process, and while I didn't get everything I asked for I'm pleased the FY13 budget includes a significant increase in financial support for the Virtual Chapters. Many people put a lot of work into the budget, but no two people deserve credit more than VP of Finance Douglas McDowell and Accounting Manager Sandy Cherry. Thanks to both of them for getting us across the goal line on time. SQL Saturday I attended SQL Saturdays in Orange Co. CA and Phoenix. It's always inspiring to see the enthusiasm in the community for learning and networking. These events are successful due to the hard work of many volunteers. Thanks to the organizers in both cities for all your efforts. Next Up This quarter we'll be gearing up plans for the VCs at the Summit and exploring ways the VCs can best support PASS' Global Growth work. I'll also be wrapping up work on the Code of Conduct and attending a Board meeting in September. And I will be at SQL Saturday #144 in Sacramento later this month. Here is the language of the Code of Conduct I have submitted to the Board for consideration: PASS Code of Conduct The PASS Summit provides database professionals from a variety of backgrounds with an opportunity to connect, share and learn.  We value the strong sense of community that characterizes this event and we seek to foster an inclusive, professional atmosphere. We are dedicated to providing a harassment-free conference experience for everyone, regardless of gender, race, sexual orientation, disability, physical appearance, religion or any other protected classification.  Everyone at the Summit is expected to follow the Code of Conduct. This includes but is not limited to: PASS Staff, Exhibitors, Speakers, Attendees and anyone affiliated with the event. Participants are expected to follow the Code of Conduct at all Summit events, including PASS-sponsored social events. Participant behavior Harassment includes, but is not limited to, offensive verbal comments related to gender, race, sexual orientation, disability, physical appearance, religion, or any other protected classification.  Intimidation, threats, stalking, harassing photography or recording, sustained disruption of talks or other events, inappropriate physical contact and unwelcome attention will also be considered harassment. Similarly, sexual, racist, derogatory, threatening or other inappropriate language and imagery are not appropriate for any conference venue, including sessions.  Recourse If a participant engages in any conduct that is prohibited under this Code of Conduct, the conference organizers may take any action they deem appropriate, including warning the offender or expelling the offender from the conference. No refunds will be granted to attendees expelled from the Summit due to violations of the Code of Conduct. If you are being harassed, witness harassment, or have any other concerns, please contact a member of conference staff immediately. Conference staff can be identified by their “Headquarters/Staff” shirts and are trained to handle the situation appropriately. A Code of Conduct Committee (CCC) made up of the Executive Manager and three members of the Board of Directors designated by the President will be authorized to take action in response to an incident or behavior that violates the Code of Conduct.

    The Real Architects of Los Angeles: OTN Architect Day in LA - Oct 25 No gossip. No drama. No hair pulling. Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Why IT is a profession in 'flux' | ZDNet I usuallly don't post two items from the same person in one day, but this post from ZDNet blogger Joe McKendrick deals with some critical issues affecting those in IT. As McKendrick puts it: "IT professionals are under considerable pressure to deliver more value to the business, versus being good at coding and testing and deploying and integrating." Cloud, automation drive new growth in SOA governance market | ZDNet "SOA governance tools and processes learned over the past decade are now underpinning cloud projects as they scale across enterprises," reports Joe McKendrick. But there remains a lack of understanding about SOA Governance. For a broader discussion of the importance of IT governance check out the lastest OTN Archbeat Podcast: By Any Other Name: Governance and Architecture How I Simplified the Installation of Oracle Database on Oracle Linux 6 Michele Casey's update of Ginny Henningsen's original article.

Checking whether the current user is in a BPM Swimlane | Christopher Karl Chan "The tricky part here is that the ADF Task Details Form is in fact part of a separate J2EE application to the main workspace," says Oracle Fusion Middleware A-Team member Christopher Karl Chan.

  • Using INotifyPropertyChanged in background threads

    - by digitaldias
    Following up on a previous blog post where I exemplify databinding to objects, a reader was having some trouble with getting the UI to update. Here’s the rough UI: The idea is, when pressing Start, a background worker process starts ticking at the specified interval, then proceeds to increment the databound Elapsed value. The problem is that event propagation is limeted to current thread, meaning, you fire an event in one thread, then other threads of the same application will not catch it. The Code behind So, somewhere in my ViewModel, I have a corresponding bethod Start that initiates a background worker, for example: public void Start( ) { BackgroundWorker backgroundWorker = new BackgroundWorker( ); backgroundWorker.DoWork += IncrementTimerValue; backgroundWorker.RunWorkerAsync( ); } protected void IncrementTimerValue( object sender, DoWorkEventArgs e ) { do { if( this.ElapsedMs == 100 ) this.ElapsedMs = 0; else this.ElapsedMs++; }while( true ); } Assuming that there is a property: public int ElapsedMs { get { return _elapsedMs; } set { if( _elapsedMs == value ) return; _elapsedMs = value; NotifyThatPropertyChanged( "ElapsedMs" ); } } The above code will not work. If you step into this code in debug, you will find that INotifyPropertyChanged is called, but it does so in a different thread, and thus the UI never catches it, and does not update. One solution Knowing that the background thread updates the ElapsedMs member gives me a chance to activate BackgroundWorker class’ progress reporting mechanism to simply alert the main thread that something has happened, and that it is probably a good idea to refresh the ElapsedMs binding. public void Start( ) { BackgroundWorker backgroundWorker = new BackgroundWorker( ); backgroundWorker.DoWork += IncrementTimerValue; // Listen for progress report events backgroundWorker.WorkerReportsProgress = true; // Tell the UI that ElapsedMs needs to update backgroundWorker.RunWorkerCompleted += ( sender, e ) => { NotifyThatPropertyChanged( "ElapsedMs" ) }; backgroundWorker.RunWorkerAsync( ); } protected void IncrementTimerValue( object sender, DoWorkEventArgs e ) { do { if( this.ElapsedMs == 100 ) this.ElapsedMs = 0; else this.ElapsedMs++; // report any progress ( sender as BackgroundWorker ).ReportProgress( 0 ); }while( true ); } What happens above now is that I’ve used the BackgroundWorker cross thread mechanism to alert me of when it is ok for the UI to update it’s ElapsedMs field. Because the property itself is being updated in a different thread, I’m removing the NotifyThatPropertyChanged call from it’s Set method, and moving that responsability to the anonymous method that I created in the Start method. This is one way of solving the issue of having a background thread update your UI. I would be happy to hear of other cross-threading mechanisms for working in a MCP/MVC/MVVM pattern.
