Hello,
I've found out there are programs which are able to decompile VFP application (.app or .exe) to the sources. I really don't like the idea this is at all possible. I also heard these decompilators can also "protect" the app against further decompilation. This is nice, but I do not like the idea someone created a program and forces me to buy a protection against it either.

Does anybody know what this protection is based on? Is it possible to protect the app somehow without buying the decompiler?

Thank you.
