    exe work but dll does not work?

    Hello everyone,


    I have written two simple programs (source codes are the same),

    1. In an exe, loading a class from another COM component by invoking CoCreateInstance;

    2. In a COM DLL, loading a class from another COM component by invoking CoCreateInstance;

    1 success but 2 fails. I am running in the same environment (machine) using Visual Studio 2005. Any ideas of this issue?


    thanks in advance,
    George

    I work on a massive COM/DCOM project every day with dozens of DLLs containing COM components in VS2005.

    First things first though. What is the return value of CoCreateInstance?
