You could create an offscreen window in genericFormat, then use WinGetBitmap to get at the bitmap which is yours to manipulate. Then
copy that offscreen buffer to the screen. That'll give you double buffering at a decent speed. About the suggestions by kcorey: Don't use WinScreenLock, it's a memory and performance hog, and is mostly unsuitable for the purpose of fast double buffering. And *shameless plug* yes, take a look at Razor! www.tilo-christ.de/razor :-) It gives you both "pure" OS based double buffering and game screen manipulation, as well as speed optimized assembly language, slightly evil bit-banging routines.
