    COM Registration

    A COM DLL is being registered using the regsrv32 command from the command line. There is no error message being displayed as a result of execution of the command. How can one determine if the COM registration has indeed been successful ?

    When you start the RegSvr32 process, call GetExitCodeProcess and check the return code.

    Hi Arjay, this command is being executed from the command line on the command prompt and not from code.
    Is there anyway to look at some location in the registry or something to check if the registration is successul

    open registry "regedit" and try searching for your COM class name. UUID or some other reference identity in the registry .. if migh tbe present if it is registered properly.

    Did you write the COM object?

    You have to provide some definition to 'registration success' thing.

    PS. I can imagine only one reliable way: running test application that creates coclass object and makes sure it's functioning.
    Best regards,
