Why do you want OCX/VBX/DLL solution?

If individual pixels are what you want to examine, look up the
.Point method in your help. If it's whole blocks of pixels you
want to deal with, look up the .PaintPicture method in the
same place. If you're using earlier than VB4 then you *might*
need to use the BitBlt API from a DLL.
