OK, I don't know in detail what the problem is with, so I'll risk
assuming that you're saving and reusing the BitmapPtr, which would be
meaningless once the Bitmap is reloaded into a different memory location
(since the header itself contains pointers). Whenever I have structures
which include pointers to other structures, I resort to serializing the
data with custom code (and a custom file type), e.g., write(nInt);
write(strlen(szData)); write(len,szData); write(*pBMP)...
I may have misread your problem, but I tried. :)
