Hi. I am preparing to sell my source code to users/developers and need a simple method to protect someone from creating an executable and selling it based on my source code. I want to 'license' a company for the source code usage but stop/prevent the licensed company from giving/selling copies of my source to other companies without compensation for me. I currently use safeserial for compiled copies but the problem with it is if you mess with the files (even accidently like copying them, deleting them, etc.) the serial number becomes invalid, also if you need to reinstall the app you need a new serial number. I dont want to have to generate serial numbers for ever for people as the code will be sold as-is with pay for support if required and the client I am going to sell it to first tends to have network issues that invalidate the serial number. Is there a way to build a non visible/non accessible method or something that I could code to match a customer's name (user will input in the application). I would like the solution to be entirely in foxpro as I dont have access to a c compiler.

TIA,

Sandi Cassidy
