• Software Development for Windows Vista What' the difference between EventDrivenActivity and HandleExternalEventActivity

  In my mind, they all block workflow until an specified event is raised EventDriven is a sequence *container* for a specific pattern of activities - specifically that the first activity in that sequence must implement IEventActivity. HandleExternalEventActivity happens to be one of the built-in activities that implements IEventActivity - and therefore will wait until it receives its event (under the covers this is a message received on a particular named queue). The other OOB IEventActivity activities are Delay and WebServiceInput. ...Show All

• Visual C# List/ArrayList to Type[] array reference

  Hi, First off I'm a c++ convert and am liking C# so far. I am currently using a List<Matrix> and am hoping there's an approach that will let me convert it to a Matrix[] without doing a deep copy. The only shallow function I can find in List or ArrayList (either will work for me) is GetRange but that still returns a List/ArrayList. Is there a way to get at the memory inside the object As you can see below, every iteration, I have to copy a batch into a static array. I'm just hoping for a better way to do this. Seems pretty basic to me to get the array reference inside a Collection object yet I can't seem to figure it out. Matrix[] marr = new Matrix[nInstances]; m_matrixList.CopyTo(nOffset, marr, 0, nInstances); effect.Param ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. incrementing a value over time?

  do you know how I can create a function that runs every second or know of one that runs every second so that I can use it as a means of incrementing a value over time, is their a way to do this, also code would be a big bonus. Create an "elapsed time" member variable in one of your classes - your Game class, for example.In your overridden Game.Update() method, update the member elapsed time using the GameTime that was passed in. When the member elapsed time has passed 1 (for one second), you know that one second has passed. Subtract the 1 second from the variable and then do whatever it is you wanted to do. Your Update() method, in your Game-derived class: protected override void Update(GameTime gameTime) { this.elapsedTime ...Show All

• Visual Studio DSL Tools and Text Templates.

  Hello, is it possible to construct an item that combines a .DSL designer (say with a designer specific extension), and the result of a text template (maybe even more) I want to match the hierarchical file construction of the default Form/Control designer. Something like: MyModel.cs - MyModel.cs - MyModel.ssd MyModel.cs - MyModel.ssd or: MyModel.ssd - MyModel.cs Ofcourse the idea is that by single clicking the default designer pops up. But the user should be able to see the (automagically updated and thus read-only) generated source of the diagram. To summarize i guess i have two questions: Is it possible to merge Designers and the result of text templates under one single projectitem Is it possible to automatic update the ...Show All

• .NET Development Clipboard object throwing exception on Web Server 2003

  I'm about at my wits end on this one - so any help would be much appreciated I've developed a web ASP.Net application under .Net version 1.1, tested it, and ran it on my WindowsXP Pro. laptop IIS 5.1 web server.  It runs fine.  The ASP.Net code behind pages call calls methods from a custom developed assembly (built to partition out functionality).  This assembly writes to and reads from the clipboard object.  Unfortunately interacting with the clipboard is a necessary evil at this conjuncture in the development cycle. Now when I moved the application to a Windows 2003 Web Server (via a .msi pulled together by a VS Deployment project) and execute the application I get the following exception mes ...Show All

• Visual C# Another word about Enumerations

  Hello All. I wonder if I could get you folks to check my thinking on this, because I'm wondering if there isn't some aspect of enums that I'm overlooking. Now, as I understand it, an enum consists of an ordered set of named integer constants with the ability to reference the name of the constant as a string. So, the salient points are these: named: good for code readability constant: good for switch statements integer: good for control statements and indices; bad for type consistency string: good for basic output; n/a for localized output Okay, the app I'm designing has several collections and matrices representing various states and lookups, so I really need named integers for indexing in order to keep the cod ...Show All

• Smart Device Development Custom Application.Run()

  hello, The Compact Framework requires the developers to start the application message loop on a given form. Therefore there is no Application.Run() method that can be called without a form instance as a parameter. For our applicationstructure this is very annoying, and I know that the OpenNETCF variant allows this. The problem is that we cannot use this library in our projects. Does anybody know what is needed to implement this method by hand Thanks in advance. Application.Run () does what a classic Windows message loop would do. The core of the implementation may look like this: while (NativeMethods.GetMessage ()) { NativeMethods.TranslateMessage (); NativeMethods.DispatchMessage () } With some tests you should be able to get ...Show All

• Visual Studio Updating Major and Minor versions from TFSBuild.proj file

  I would like to be able to set the AssemblyMajorVersion and AssemblyMinorVersion from my TFSBuild.proj file and am using the AssemblyInfo Task to update the BuildNumber and revision. Is this possible to do I've looked around at the posts such as http://blogs.msdn.com/gautamg/archive/2006/01/04/509146.aspx and got AssemblyInfoTask working fine. I can edit the \AssemblyInfoTask\Microsoft.VersionNumber.targets file to override the Major/Minor versions there and also each individual AssemblyInfo.vb in the projects I'm building, however I would like to be able to pass through the Major/Minor version from the TFSBuild.proj file. If I do what Gautamg suggests in the above post it doesn't work. Any ideas - Ossian ...Show All
