• Visual Studio 2008 (Pre-release) exception when closing window in button event handler, only when using keyboard

  I ran into an interesting problem, could this be a bug in the Windows.Interop layer In short, I run a win32 app, where a WPF window is opened from managed C++ code. The window has an OK button: <Button Name="okButton">OK</Button> okButton.Click is handled in the C# window implementation, and forwarded to another handler in the managed C++ code, where the window is eventually closed (using Window.Close()). This works nicely, as long as I'm using the mouse to hit the "OK" button. But, when I tab to the button, and hit return, a Win32Exception is thrown after the C# event handler returns (at which point the window is already closed): System.ComponentModel.Win32Exception occurred Message="Invalid win ...Show All

• Visual Studio Any tutorial for GAT?

  I am wondering if there is any good tutorial available anywhere that would describe how to implement typical guidance scenarios in guidance packages from the beginning to the end Materials that I found so far are not satisfactory for the following reasons: 1. The latest Hand-on Lab seems to be created for the Dec 2005 version of GAT and cannot be registered with Jun 2006 version; 2. Most articles either describe the theory without specific examples or give specific examples of small tasks without describing a big picture; What I am looking for is a specific roadmap from A to Z starting from generating a stub for a guidance package and continuing with specific steps required to implement a scenario until the package is successfully ...Show All

• Visual Studio 2008 (Pre-release) TCP commands through WCF

  Hi, Sorry if this is really straight forward I am just a little confused and a little inexperienced with TCP communications, and WCF for that matter. I have an existing third party application that accepts commands through TCP (I can use telnet easily to send commands). I would like to use WCF to write an application for sending commands to this application. I see it is quite easy to communicate over http as I can generate a Service Reference. I am not sure where to start for my case. I realise this is a lot to explain but maybe someone know of a good example of this kind of thing somewhere You may find it easier to put System.IO.StreamReader and StreamWriter on System.Net.Sockets.TcpClient.GetStr ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Are Direct X Sound Problems Common Amongst End Users?

  Hello, First I'd like to apologize that this question isn't related to developing games. I am creating an interactive CD, and I looked around for a general Direct X board, but none are really active anymore. If anyone could help, I would certainly appreciate it. I am a multimedia designer, and I am creating an interactive CD for a client that will go out to about 1500 people. On past projects, I have used one WAV file for the entire project, but on this one, I'd like each of about 9 pages to have a distinct music file, so I think I'd need a smaller format like MP3. However, my multimedia authoring software requires that Direct X Sound be enabled for MP3. I am a little leary of enabling Direct X sound because several years back, clien ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. soundBank.GetCue("xxx").IsPlaying - does it work?

  Does anyone know if the .IsPlaying value works properly I would assume that the code I wrote below would cause the computer to play the sound only if another one is not already playing, but it still goes too fast for my taste for ( int i = 0; i < ammo;) { if (!soundBank.GetCue( "click" ).IsPlaying) { score += 25; soundBank.GetCue( "click" ).Play(); Draw(); i++; } } George is correct. When you call GetCue() on the SoundBank, a new Cue object is returned each time. So, in your example above, the call to GetCue() for IsPlaying is returning a different Cue object then the call to GetCue() for Play(). However, each call to GetCue() creates a new Cue ob ...Show All
