>>>VFP debug off and "encryption" is low to no protection from even the low to average crackers simply because it can be cracked using off the shelf products. It's a no brainer. The best protection for VFP apps is probably products like Konixse and Thinstall, but even they probably only rank as a medium level protection difficulty against a true expert cracker.

Yes, I agree with you on this fact.
