• Game Technologies: DirectX, XNA, XACT, etc. Targeting older machines

  Hi there. I guess part of this is more of an opinion question. I want to target older machines that may not have up-to-date graphics cards. Right now I am using a game engine that gives the developer the option of using DX8, DX9, or its own software driver. To compile the engine, I naturally need the DirectX SDK. Problem being that the latest realeases don't have DX8 support. So the question becomes: Is DX9 a 'safe' way to go f ...Show All

• .NET Development Usage of ToString and ToInt32

  We can use ToString this way: int i = 5; Response.Write(i.ToString()); But why can we only use ToInt32 the other way: string s = "5"; Response.Write(System.Convert.ToInt32(s)); Why can't we just simply use "s.ToInt32()" I agree that it would be nice, unfortunately with it though we face the slippery slope theory that by adding ToInt32(), arguments can then be made for ToInt16(), ToInt64() and ToJustAboutAny ...Show All

• Visual C++ Can you use the Base Class Library from unmanaged code?

  Can you use the .NET Framework Base Class Library from unmanaged C++ I would like to know because then I can do Windows Forms in asm to have a laugh about. It will be very ugly, like COM in asm (urgh), but I don't care: it is just a bit of fun for me. Thanks Can't you use regasm.exe and tlbexp.exe to make .NET Assemblies visible to COM If so, can I use this on System.Windows.Forms.dll ...Show All

  Sorry if someone already covered this, but I can't find anything about it.

• Visual C++ .NET Framework - why does my program require it?

  Hi, I've got myself a little demo program created. It uses the Irrlicht 3D engine and the RakNet network library to provide a drawing window - basically anything drawn in the window on one of the clients gets passed across, via the server, to every other client. I'm quite happy with the way it works, functionally it's just fine. But to run it requires the .NET Framework 2.0 Beta. I don't understand why, because it's not using any .NET code what ...Show All
