Myfunc=(cfunc)G etProcAddress(( HMODULE)hLib, "Myfunc");

You didn't check Myfunc for NULL before using it. If GetProcAddress can't find your function in the DLL, it returns NULL.

Was the DLL built with a C++ compiler?? If so, you have top do some things to the DLL when you build it to defeat the C++ name mangling feature. If you don't, the mangled function names are the ones in the DLL. When you are requesting "Myfunc", which is not mangled, GetProcAddress will will never find it.
