You can compress your app with KONxISE from http://www.yqcomputer.com/
Refox can't decompile apps compressed by KONxISE.
You can also protect your app with REFOX against other REFOXes. There is a
Chinese tool on the web called "unfoxall" which can decompile Refox branded
programs.

Use refox and brand it.... I've seen a few people say they can crack refox
encrypted exe's -- but I've sent samples, but no one has ever sent me back
decrypted code.

If you use VFP's "encryption" it does nothing but make it not compress well;
refox and others can still decompile it.

This will only "secure" your EXE (not any .APP or DLL's)

I've tried it; it seems to be able to do small apps, but not larger "real"
apps... especially if you use refox level II

Sorry Paul,

But Josh is referring to the KONxISE test, not the Chinese tool.

What he also said was ...

I've tried it; it seems to be able to do small apps, but not larger "real"
apps... especially if you use refox level II

As well as trying konxise he also tried the chinese tool.
