>I have seen some software on the net that will uncompile and decrypt applications in VFP. I was wondering is there a truly safe way to distribute applications and protect source code.

C/C++ native code?

If VFP can decrypt and run it, then even if there is no decrypting program now, there will be one in the future. At a minimum, VFP is extracting and executing p-code at runtime, so the person really interested in spending the time and effort to extract the source can and will as long as your source is worth more than it costs them to do so...

It's cynical, but if you're already assuming that people will steal your source, be paranoid and assume that smart people will steal your source.
