Has anyone heard of this compiler? If so, any comments about it? http://www.baiyujia.com/vfpcompiler/en/default.asp
It seems to work. However it relies on modified VFP runtime files and disassembly of the original files. There are also modified copyright statements in the product. This might or might not be legal in your country and additionally might require that you get in writing from Microsoft that they won't release a 64-bit version, or fix any of the bugs. That's the case in Europe, anyways.
I'd consult a lawyer that specializes in intellectual property and liability issues, but that's just me.
