Hey everyone, this is my first post on GameDev.net. I know C/C++, and some x86 Assembler. I'm creating a simple Pong game (using OOP), and I have a little question (Win32 / C++). I put the wnd proc in a class, and noticed that I cant access any members of the class. eg;
[SOURCE]
// in _CMain::WndProc

  case WM_PAINT:
  {
    ...
    RenderFrame (hdc); // why doesn't this work?
    ...
  }
[/SOURCE]
The above should call _CMain::RenderFrame (), except I'm getting an error from my compiler (must use . or -> to access this etc..) I'm guessing this has to do with the wnd proc beig static, but is there any way around this? Thanks;
