I was wondering if anyone could tell me a good way to get specific coordinates from a memblock. I would like to use it to check for certain colors. I know the header is 12 bytes, and I believe the pixel data is 2 bytes each, but I can't figure a way to call specific pixels. Any help or direction to help I get would be greatly appreciated. Thanks

Pixel data is 4 bytes (a DWORD). You ought to download and read Tutorial 9 because it has a section on "translating from screen X,Y coordinates to MemBlock locations" which sounds kinda right up your street, no?

Cheers,

That is probably exactly what I need. The only question is where can I get Tutorial 9?
Thanks a million

It's actually a DBPro Tutorial available from this site (see the link on the home page) but the explanation inside should apply to any memblock.

Cheers,
