>>Try Enigma protector. I bought it, far more better than Refox. It also bundles .dll, .ocx files too and virtual register at target computer. You will have one exe, no setup needs anymore.

Unfortunately, somebody who knows how can peel the VFP project out of Enigma Protector or any of the commercial virtualization (walling) systems in a matter of a few minutes.

For an example, check out Craig Boyd's challenge on Foxite a few years back. It doesn't matter how high you make the wall around a VFP app, since the way VFP functions usually allows you to emerge inside the wall in the middle of the running app and scoop everything.

In response, Refox has added extra protection including disabling the most accessible hack vector, Defox does varying encryption of sensitive code so now you need disassembly skills, and VFP Compiler shifts most of the project into a C++ dll that needs to be disassembled in full.

In public literature, only two people have demonstrated successful penetration of those last three systems- and then only a few lines of code for Defox and VFP Compiler rather than a whole project. I'm one of them, FWIW.
