the file that the show function is from was automatically generated when i complied a idl file. i haven't changed any of the code from the website i linked in the first post. can you download the code and test it yourself?
This cannot be done by hand. RPC is done this way only. We create stubs and compile them into a C code, which generates server and client code. Then add your own code and lots of things I don't remember now..
I think this is more suitable to post in windows forum.
