imprints comparing

is there any way in vb to know if a scanned image of an imprint is the same one stored at the first time.

i think it's a hard job because the direction and the place

anyway, is there any code to do that?

thanks

I don't know what an imprint is, but if you want to compare one file to another that was loaded before, create an MD5 checksum and save it somewhere (registry?), then compare it to the checksum of the second file.

You can probably do that with an image in memory too.
