Bingo!!! Might happen you've solved the problem: have one empty DLL as a template and populate it with resources every time you need a new resource storage for a project.
The UpdateResource did not work with VFP executables in my test. It just cut them, I guess because of some specifics of VFP executable format.
I hope this function will work with a regular DLL.
