(1) Try checking the return values of the method calls into the various CGapiSurface objects. Are they returning success or failure? If success, is your code doing what you think it's doing? If failure, why?

(2) Try using breakpoints to determine if values you think are set really are. (Hint: they aren't)

(3) Try using breakpoints, and determing if the code you assume is running really is running. (Hint: it's not)

(These are basic software debugging steps, so it's important to learn them. Otherwise, you might as well just contract someone to write your code for you.)

Hi,
Just a couple of questions:
What size is your image?
What size is the screen you try to display it on?

I see you BltFast your image with this code:

If the image is bigger than the screen it won't appear.
If it is the case, instead of the NULL pointer (just after the surface pointer in the call to BltFast) use a pointer to a RECT you set smaller than your screen.

It may not help but that just caught my eye.

Vincent.
