• Game Technologies: DirectX, XNA, XACT, etc. How to change one class to another or how to include derived in base

  Hello guys, I've been making a 3D space game in DX9 and I've run to the following problem. I have base class TELESO for every object in the space and derive needed classes from it(asteroids, ships,etc)... Well, maybe you will find this solution bad, but ...its the only thing I could do...: I want to spread chunks from object when it is destroyed. However I cannot divide object into smaller parts ingame, though I can make them in 3D program and load them as extra objects which I put into Sprite vector after the parent object dies. Anyway, the problem is that I have a derived class Chunk for those small parts - because I want to be ...Show All

  Does C# provide anything that allows a file system implimentation that would allow you to hook up to a database on the back end and have windows see it as a filesystem on the front end Thanks, Marty Some thoughts.

• Smart Device Development Serial Port Mapping Problem on Pocket Pc 2003 Emulator

  Hello all; I am developing an RFID reader project, using VS2005 C#.NET on pocket pc emulator. My rfid reader device is connected on serial port of my computer. I can read and write to serial port of reader on pc application, but when I try to use emulator in my software, I fail to communicate. My device is on COM2. I map it to serialPort1(I guess it means COM1) on emulator, then I write my software which tries to communicate with COM1, then I deploy it. It seems to open the port, but when I try to send message, the program freezes. The weirdest thing is that, I can only open COM1 port on emulator, even if I map my de ...Show All

• Visual Studio Tools for Office Add-in not load in Word when running with Office XP and .NET 2.0

  Hi, We have developed a shared add-in to be used in Word and PowerPoint. It works well on the targeted Office versions (i.e. XP and 2003) when .NET 1.1 is installed. However, when trying to run on a system that has Office XP and only .NET 2.0, the add-in would only load in PowerPoint but not Word (but no error message). We have compared the macro security settings in both applications and they are the same. The add-in has not been disabled, as can be seen with a LoadBehavior of 3 in the registry. The add-in is installed as a global add-in (i.e. registered under the LocalMachine key). It was developed with .NET 1.1 and the Office XP PI ...Show All

• Visual Studio Tools for Office Refresh of Data / Hiden Sheet VS New VSTO Model
