Did REGSVR32 reported the registration successful?

If yes, search for "mydll.dll" in the registry. You'll find a ProgID registry key among the keys for your class. The value of the ProgID is what you have to use with CreateObject.

BTW, how did you build a multithreaded COM DLL in VFP? VFP is not multithreaded yet.
