[JDEV] (HELP!) How to get a JabberSession pointer from JabberCOM

[Michael F Lin]

Jim,

Make sure you are calling CoInitialize( NULL ) in the thread. If this does
not help you must examine the HRESULT returned to determine what the
problem is. You can use the compiler support class _com_error to extract an
error description as a string. Read more about this in the MSDN
documentation.

      JabberCOM



Hi Mike,

    Thanks for your help.
    I tried to change the __uuidof(IJabberSession) to
__uuidof(JabberSession), but i still got error. Indeed, i tried using
CLSID(f6c7a239-b7b1-11d3-aecb-00a076a018e8). I still can't get the pointer.
Can anyone help me?

Thanks very much.
Jim
