Could someone point me in the direction to locate a source code for writing a patch in VB?

Thanks

Hi,
open the target with the "open"-command(open "test.exe" for binary as #1), write the new bytes with the "put"-command and close the file with "close #1". For reading bytes from a file use the "get"-command.
Check VB command reference for details...
hope this helps

cheers, I'll give it a shot.
