I'm a beginner and I dont quite understand the use of surfaces and bitmaps.
can anyone give me a simple code - just pasting a picture as the background, and another picture on it.
thanks.

Read Tricks of the windows game programming gurus (ISBN: 0672323699; 2nd edition) (amazon link below), or go to gamedev.net and look for directdraw tutorials.

Define a surface then load the image into the surface with CreateSurface, depending on what sort of image you have will determine how you use CreateSurface; there are a few different methods. Then in your ProcessFrame method Blit that surface into the backbuffer.

In general:
[some init method]
GapiSurface surface;
surface.CreateSurface(...);

[some ProcessNextFrame method]
backbuffer.Blt(x, y, &surface, ...);

Thats just off the top of my head, some parameters and such may not be correct, and spelling.

There's a few tutorials on our website forums () that might help a bit. The GapiDraw samples are really the key to understanding it all though. You might want to pick up the book Pocket PC Game Programming by Jonathan Harbour. While its not GapiDraw specific, it might be a good starting point for you.
