    SHAutoComplete/COM Problems

    Hi all.
    I've been having trouble for the past few days trying to get SHAutoComplete to work in my program. Basically, I've implemented it dynamically (LoadLibrary/GetProcAddress) but when my app reaches the end, two threads (i presume created by the two calls to SHAutoComplete) remain active and my app never exits. Here is my code for COM and SHAutoComplete. If i remove this code, the app terminates when expected and I've also tried initializing COM as multithreaded (CoInitializeEx) which failed entirely. If anyone could take a look at it and see what I'm missing I would really appreciate it.

    Thanks in advance, Ehtyar.

    [edit]
    I've also tried moving the calls to Co(Un)Initialize to the inside of the calls to LoadLibrary/FreeLibrary with no success.

    I normally use LoadLibrary before the messsage loop begins and call FreeLibrary after the message loop.

    I do......
    Code:
    //Before Dialog Creation: AKA before CreateDialogParam
    <snip>
    hShlwapi = LoadLibrary("shlwapi.dll");

    Your app should exit either when you return from WinMain or when you call ExitProcess, regardless of any threads still running. Are you sure that one of these things is happening?

    I didn't necessarily mean that the threads are what's preventing the app from exiting, i just assume they have something to do with it because when i remove the Co* code, they're no longer there before the app exits as it should.
    At the moment, I am getting around this problem by calling ExitProcess before returning from my entry point (i don't use WinMain), but it's an ugly hack, and i shouldn't be doing it, and since it is clearly my accessing COM that is causing this problem, I'm assuming I'm doing something wrong.

    It sounds like you adhere to the old-fashioned theory on how processes exit.

    ExitProcess should be called to exit a process. Typically, this is done by the wrapper code for main or WinMain. If you define your own entry function, it is your responsibility.
