Dmitrt,

To decompile a fox exe or dll you can use ReFox from www.xitech-europe.co.uk this utility can also protect your source code so that it cannot be "refoxed" without a password.

They also sell a cool utility call KonXise which takes your application and encrypts it so that even ReFox can't get the source back. As a bonus it will also compress the VFP executable if the project wasn't compiled with encryption.
