• Game Technologies: DirectX, XNA, XACT, etc. Bug where it becomes impossible to save your files

  Hi all, Has anybody encountered a bug where somehow XNA game studio express doesn't allow you to save your files I've encountered it once (and I forgot the message it popped up unfortunately), but I thought it was a one-off thing. Then a co-worker told me he got it quite regularly when starting and stopping programs. Just wondering if this is something that more people are experiencing. At the time I had two XGSE's open, one with my (saved) project, and one with a temporary spacewar project. Unfortunately when I was trying to repro this bug, I couldn't get it to do this again. My co-worker gets it when editing files while the program is running. Cheers, Nick Waanders This occurs in C# Express correct This ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. mesh clone and dispose bug

  this is a strange one... Mesh mesh = Mesh.FromFile( "tiger.x", MeshFlags.SystemMemory, device, out materials ); Mesh newMesh = mesh.Clone( MeshFlags.Managed, mesh.VertexFormat, mesh.Device ); mesh.Dispose(); // Dispose the original newMesh.Disposed == true <--- what -- the new one is now also disposed mesh.UnmanagedComPointer and newMesh.UnmanagedComPointer are not equal what going on here ob. the original and the cloned are referenced somehow... Its a known bug that I reported years ago that apparantly never got fixed.

• Windows Forms Arrow Keys on a User Control in .Net 2.0

  If I have a form and want to trap keyss, I can use the KeyDown event to trap and detect which keys are used. This includes the arrow keys.

• .NET Development programmatic access to sqldatasource dataset

• Visual Studio Express Editions Browser waiting

  I'm trying to put together a relatively simple script for a webbrowser game that provides a service in-game by interacting with the site and doing some stuff with the material within it. I have gotten around most of the problems of how to make it work, but there's one thing that I don't know how to do properly: making the script wait for the browser. In short: I'd need some way of making the script check that the browser has finished downloading the page before attempting to do anything else. Here's a snippet of what I currently have: Public Sub Form1_Load( ByVal sender As System.Object, ByVal e As System.EventArgs) _ Handles MyBase .Load WebBrowser1.Navigate( "http://www.WEBSITE.com" ) End Sub ...Show All

  Hello, I want to use WF for Workflows with Navision. I have some questions concerning this: 1) How could the worklfow be enabled Are there some standard-options of WF I thought about using a COM-Object in the C-Side/Navision.

• SQL Server Slow VS2005 performance while designing reports

  I'm designing SSRS 2005 reports in VS 2005 Professional Edition. I have 2 performance problems that make me really angry: 1. Designing reports takes so long! After each click I have to wait a couple of second, the more complicated the report is, the more time I have to wait. The processor is on 100% during this "waiting". I don't know what he does, maybe updating the .rdl file after each change. But it's really horrible! Right now I'm designing a report for my customer with about 10 data regions and only 30% of my time is designing it, the rest I just sit and wait. 2. Dynamic hiding of solution explorer tab Terrible ! maybe 20 seconds until it hides! Please help! Do I need a fix or is it a common issue I haven't f ...Show All

• Visual C# System.Char[] question

  I am running a continuous download of records from a server. To monitor the progress I use a progress bar and at the same time I send symbols to a RichTextBox via an invoker. The symbols are just added to the previous content with a single space separating them. It is a continuous line for symbols but they are wrapped around in a small window thus I see about 6 symbols per line. At certain time I need to start a new paragraph, so to speak. I decided to send this character: char [] CR = new char [ 13 ]; to the textbox: Then the first symbol of the next paragraph is combined with CR like this: CR+symbol. Instead of getting a new line I get this in the window: System.Char[]ABCD where the ABCD is one of the symbols. In othe ...Show All
