Finger Print Class[^] This will explain how to get unique key. And you can use it with algorithm to get serial key. If you do not wan't to protect then my suggestion is a Demo mode. You have limited functions, and when someone bought it, they get to download full version. Any approach you take, it will be pirated.

You mean you want an application that generates barcodes OR you want to genereate a "barcode application", which could both mean that it can create OR read barcodes (thorough some input device like a webcam, a scanner or a barcode reader connected to the comp). Both should be possible. To generate barcodes you can either use a barcode font as someone already suggested, or you can try to check out how barcodes work (there are loads of infoes about it on the net, Google is your friend...) and write your own method of generation, also there are some libraries i believe around the net for such a purpose. Reading barcodes thorough a webcam or such input device is a much more problematic task.

Hi Eswar, This is Carlo. Looks like you keep ignoring received answers to previous requests about the same argument.
