If you want to protect you programs (vfp or others) you can look at programs like:

http://siliconrealms.com

http://thinstall.com

and for VFP specifically you can try www.xitech-europe.co.uk

However, all can be cracked but I think that if you have a 90% solution its probably good enough for most apps.
