Verifying

Hi,
I am making a VB program to prevent documents (scores in .awd format) from being distributed illegally. The documents can only be opened in my 'Shake-It' program. The program works, (see my site) but things can be more sophisticated.

1) Is there a way to protect a document with a password from code? Users are not allowed to see this password.
2) Is there a way to identify a computer? Now the program generates an IDcode on first run, and stores it with SaveSetting(). Smart users can copy this ID to other comps.

For #1) I believe you are looking for some sort of encryption, am I correct? If so, search www.planet-source-code for "Encryption" There are all sorts of examples, so you can choose one that best suits you.

Thanks Megatron.
The www. planet link doesn't work at the moment, but I'll try later.
