OK, that's clear.

So you mean you've created a main.c with main() and main() will call into the
windows DLL via some function exported from the DLL. Is that right?

I'm assuming main.c linking against the .LIB created by VC++ for your DLL,
right?

OK, but we don't know what main.c looks like, what function in the windows
DLL you're calling, how it was exported (as a C or C++ function), how you
compiled and linked all this, and what the error was.
