Game Technologies: DirectX, XNA, XACT, etc. Does VC#05 Express allow class diagram creation?
I notice some people post screenshots using class diagrams for XNA projects, but I can never find it in VC#05 Express although I can in Standard. Since I'm being forced to use the full XNA experience on VC#05 Express, class diagrams can really be helpeful. Is there a way to use this feature in Express If not, it would be a great tool for students down the road when they go over class design etc. And it definitely helps out on any task! :) Unfortunately not :( My trick is that since most of my code is contained within class libraries and linked in to the XNA game project, I do all my initial design in VS2005. Since you only need the XNA class library when it contains content pipeline stuff, I can jus ...Show All
Audio and Video Development Programmatically setting the default playback device (and recording device)
Under Vista is there a way to set the default playback device programatically I've searched through the APIs but I'm not seeing it. For example, there is a method IMMDeviceEnumerator::GetDefaultAudioEndpoint(), but there is no corresponding IMMDeviceEnumerator::SetDefaultAudioEndpoint(). Can I do this through the endpoint properties Thanks for the info, Larry. I think we cross-posted because I didn't see your post when I started my last reponse. It's true there wasn't previously an api to change the default device, but the OS did not prevent us from setting our device's audio path (under XP, we can control the recording source by setting the value of a Mux control). Under Vista we can set the input li ...Show All

Visual C# attempting to use an array across a class
All events are confined to one class. It is a form Form1 class. The array is declared as follows: public static String[,] symbAndNamesArr; // then in a method I have: Array symbAndNamesArr = Array.CreateInstance ( typeof ( string ), coSymbols.Count, 2 ); for ( int i = symbAndNamesArr.GetLowerBound ( 0 ); i <= symbAndNamesArr.GetUpperBound ( 0 ); i++ ) { symbAndNamesArr.SetValue ( coSymbols , i, 0 ); symbAndNamesArr.SetValue ( coNames , i, 1 ); } // array "symbAndNamesArr" is properly filled.

Visual C++ Using floats with % and ^ operators
Why does MC++ .NET 2005 return and error when I try to compile and I use a float type varaible with the % and ^ operators Example: float temp, result; temp = 2.5; result = temp % 1; result = 2^temp; With both of these lines I get an error saying that the type float is not allowed with those operators. I have found a work around for the first but I can not mathmatically figure out one for the second problem. Is there some sort of patch to fix this I am using the % operator to modulus a number by 1 to get the decimal part of the number. This part was for converting the decimal part of the value of gold into silver or silver into copper. So 2.5 silver pieces would be 2 silver pieces and ...Show All

Visual Studio 2008 (Pre-release) System.ServiceModel.ChannelFactory does not contain a definition for CreateChannel
I am experiencing some trouble using the latest .NET 3.0 release in a web application. I've created a WCF service and have been able to successfully communicate with that service in a winforms test client using the below code, but when I try to implement this in a web application it fails. A possibly related error is that I can't use the IDE to add a reference to System.ServiceModel but I can manually add a System.ServiceModel assembly node to the web config. However, when I do this, the reference must be different than the one used in the winforms client because I get the build error defined in this post's subject: System.ServiceModel.ChannelFactory does not contain a definition for CreateChannel.

.NET Development DllNotFoundException- path problems
Hello all, I've got a project that pinvokes an unmanaged DLL and everything runs smoothly with it. The problem begins when I publish the project and install it on a different computer- I get the DllNotFoundException when it's being called, and the oddest thing is that the message says the dll wasn't found on the project's bin\debug path. The problem is that I wish to have the dll on the application startup path, but cannot use Application.StartupPath within the DllImport Attribute, since it takes only consts. Does anyone know why does the application search for the dll in the bin\debug folder Is there anyway to change this (I've tried adding the app startup path to the environment path, didn't work) Or better yet, is there a way of using t ...Show All
