Unfortunately there is no 100% way to protect an app compiled with VFP. Right now your best bet seems to be Konxise because it at least makes it a big hassle, but even so it's still possible to get the source.

>I wonder about the best way to protect it ? Using disk serial number and/or cpu serial number seems to generate a number that I can use to provide a key number seems good but I see a problem when the application is installed on a multi-user site. I don't want to provide a number for each individual pc. I would rather provide the number once. Is it possible to get a number from the server? Or maybe use the server IP number ? Or something else...
