• Visual Basic Clarification

  I have had windows vista beta 2 icons for a while now and I would like to use the in my applications, I never sell them but for personal use, it would be nice to see something that did not look like it came from Windows .000000000001 ( A version of Microsoft Windows I just made up to exaggerate the point that they look very old.) I am assuming that you're trying to load the icons up in Visual studio and it is throwing an exception saying "Invalid Parameter used" when you import. Chances are they are in a format that is either not supported by Visual Studio .NET or perhaps not even by .NET (<=2.x) ...Show All

• .NET Development do we need to call myObject=null when we finish using it or no need

  Hi, is it better to call helperD= null ; whenevr i finish using an instatiated object or no need Thanks Hi R.Tutus I have a blog entry that describes when to set variables to null: http://blogs.msdn.com/clyon/archive/2004/12/01/273144.aspx Mattias is correct; in general the JIT and GC are smart enough to know when the last time an object is referenced and make it eligible for collection without the need for setting the reference to null. -Chris ...Show All

• Software Development for Windows Vista Restore Workflow instance fails because workflow has been modified in designer

  Here's the scenario: A workflow is deployed to production with the sql persistence in place. Several workflow instances get persisted in the database. A month later, the workflow is modified in the deginer and redeployed. Now the previous persisted workflow instances fail because the old workflow and new workflow are different. Does anyone know how to fix this problem One fix would be to delete the existing workflow instances. This might not be acceptable from management. Thanks in advance Nitin Mistry Canada You can put them in the GAC if you want but there are a couple other options also. Take a look at this article on .NET versioning for more information on your options. Yes, if you make dynamic update ...Show All

• .NET Development Socket.BeginReceive different on W2K vs XP

  Help !!! I have a VB.NET (2003) application that listens for data packets of 100 bytes on a TCP port, it's been working perfectly for ages on XP and W2K3 machines. I've installed it on a W2k machine and I am getting problems it receives the 1st 16 packets perfectly on the 17th attempt beginReceive doesn't return the full 100 bytes, I have run a packet sniffer and it seems to be at the point of the TCP packet segmentation, but I have performed the operation on XP and it looks fine. This seems like a buffer issue, can anyone help Thanks It always happens when applications are running on real internet, There may be network delay which may delay receipt of your data.

• .NET Development TCPlistener for more than one Port

  Hi at all, i will use the TCPlistener for around 500 ports (OK, this sounds crazy, but I need it) It it possible to start the TCPlistener for more than one Port If not, how can I handle it Must I load 500 TCPlistener in different Threads thanks for your help Uhhhm but you can have 500 different connections to the same port, I don't see why you'd need 500 ports. E.g. a HTTP server also deals with thousands of different (and concurrent) connections on the same port. ...Show All

• Visual Studio 2008 (Pre-release) How to draw an ellipse inside a canvas at specific coordinates?

  I have a custom class that inherits from Canvas and I create instances of this as rectangles inside a xaml window. When the user clicks on one of these shapes (canvases), I want to draw a small ellipse at that point. I have successfully drawn an ellipse inside the canvas and its default location is top/left.

• Software Development for Windows Vista SqlTrackingService Beta 2 Lab 03 exercise 2 failed

  In WF hands on lab 03 ex 2, after I added the SqlTrackService, the workflow instance got aborted. I added event handler for ServicesExceptionNotHandled, it is not called. Without the SqlTrackingService, it works fine. Workflow got completed. Comment out SqlTrackingService and add SqlWorkflowPersistenceService, the program finished with each workflow persisted and completed. But I did not see any data in the database. In all the cases, there is not exception catch by ServicesExceptionNotHandled hander. The database seems OK. If I change the connection string, I will get exception "Can not connect to database".

• Game Technologies: DirectX, XNA, XACT, etc. SpriteBatch Scaling

  I've been playing around with 2D sprite rendering and have a couple of questions: 1) Is the SpriteBatch.Draw() call influenced by an effect I've been attempting to scale a 2D sprite using a simple effect which scales the world matrix in both X and Y directions without any luck. 2) If the only way to scale a 2D sprite is with the SpriteBatch call itself, then since the scaling parameter is a scaler, there is no way to control the scaling in both the X and Y directions! Is there any way to scale a 2D sprite in both the X and Y directions Thanks in advance for any advise! 1. Don't know 2. Several of the overloads have a destination rectangle parameter - you can use that to scale in both directio ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Game and GameComponent Feedback

  We've been combing the forums and the Connect database for bugs, feedback and suggestions around the application model. We still have a small amount of time to consider any other feedback you may have. So this is the thread that you post your latest likes or dislikes with Game, GameComponent, services, etc. Please scan the other threads before posting here, I'd like to just gather things that haven't already been discussed or reported elsewhere. Thanks! I think Serapth state a very important concern about components, as they need a way to state their dependencies. I had a suggestion up on connect that the xna team should remove the Game property from GameComponent class, and advice developers to inject dependencies explicitly ...Show All
