Is it possible to make a program that can rewrite a checksum? what would it include. Could someone point me in the right direction. Im very new to programming so any help would be great. Im pretty sure this would be a simple program.

If you would explain what exactly you want by a 'checksum' I could probably help you out a bit more, but I'm assuming you want a simple program that will recieve input from a user and perform some simple mathematic functions to calculate results.

If this is true, you should have no problem with it, assuming you have any kind of VB experience.

Well the industry standard is now MD5, though what's in textbooks is usually CRC (32). Both of these are very processor intensive, so it's best to use an out of process DLL written in C or ASM for VB6 (try Gnu Zlib http://www.gzip.org/zlib/).

Such algorithms are not trivial however: if this is homework or something, the one being used probably involves simple manipulation of a string/byte-array and could be done directly in VB.
