Thanks to both of you. The information I found online indicated:
ULong ignore;
UShort BytesPerRow;
ULong ignore2;
I guess if I wasn't in such a hurry to figure it out (not to mention
it was already time for bed and I had been working all day) I would
have discovered the problem.
Only other question regarding manipulating Bitmaps via C. Once the
Binary data is locked is it perfectly fine to use a standard pointer
and not bother with BlockMove(...) ?
