>Good suggestions Alejandro, but the best 'protection' has to be to simply write in VFP in the first place... since there's nobody left (except zealots whose love for the product is irrational and who, by such love, would NEVER steal code) nobody will be able to steal it anyway. < s >

Its actually a good argument, Jim, not just tongue in cheek.

Happy New Year to you. Enjoyed your case study.

>>Abdul, one strategy you could follow in order to continue to use separate files is:

>>2) Keep all other programs encrypted and set up the encryption before calling each one. I use Cryptor (from the same folks as Refox and Konxise) for encryption. It is very effective with hardly any overhead. All you have to do is make a call indicating the file and password and then go about your business with USE, DO FORM xx, DO REPORT xxx or DO xxx. Cryptor intercepts the file reads/writes at the OS level. It's transparent.
