Petzold says that you should use huge pointer for data > 64k, otherwise use far pointers. My question: I have a huge pointer to an image (512x512/8), and I want to create a DIBitmap of it. I type cast the huge pointer variable to a LPSTR and pass it to the createDIB.... function. What puzzles me is why a correct bitmap is created when a LPSTR pointer is not suppose to go over 64k. I am using BC++ and small memory model (386). thanks in advance, DaRa *************************************************************************** Dara T.
