Yes, this is another 'how to require serial code' thread. At the moment I'm experimenting, I'm not thinking about charging people for my program at this point, but I built a custom installer (which is nothing special, really) and I want my program to verify the user input. But how would I do that without listing all of the various approved serials? I want the serial to be 16-digit (####-####-####-####). Can anyone recommend a way to do this?
