I don't know much (i.e. anything ;) about WCCS, so I'm not sure what
exactly creating window means.
If you're not allowed to open any window that's a problem that we
probably won't be able to get around. You have to have a window handle
(HWND) to access OpenGL. If it's just about
having an actual displayed window that should be possible by using an
FBOWindow for rendering, which is not actually visible anywhere.
But then again, I don't use Windows very much, so I might be missing
something here. Anybody else tried this before?
Yours
Dirk
