Can anyone tell me if there is anything wrong with this function? The bitmap never shows up on the surface. You can download the entire cpp file here. All this file is supposed to do is load a 128x128 bitmap of a penguin onto the test surface, blit the test surface to the back buffer, and then flip the primary surface with the backbuffer. The image however, never loads, and I don't know why. Please help me as this has been screwing with my head, and I must figure out why it's not working.
Thanks,
Niki
