I'm seeing a crash when I call the static version of CXTPCommandBars::TrackPopupMenu where the first parameter is the CMenu pointer. This call is being made inside a DLL that dynamically links to MFC(and Codejock). It's crashing in the function below and I believe the problem is AfxGetThread is returning NULL. I think it's a manage state problem, but the message is originating from a control in the dll - the call isn't being made from the executable.

Thanks,
Karim


void CXTPPopupBar::PumpMessage()
{

    while (IsTrackingMode())
    {
        MSG msg;
        if (::GetMessage(&msg, NULL, NULL, NULL))
        {
            if (!IsTrackingMode())
            {
                ::PostMessage(msg.hwnd, msg.message, msg.wParam, msg.lParam);
                break;
            }

            if (msg.message != WM_KICKIDLE && !AfxGetThread()->PreTranslateMessage(&msg))
            {
                // process this message
                ::TranslateMessage(&msg);
                ::DispatchMessage(&msg);
            }
        }
        else
            break;
    }
}

Yes, you have to switch state in your dll.

I'm sorry I wasn't clear about that. Yeah, I am switching state but it makes no difference. Specifically, I'm calling

AFX_MANAGE_STATE(AfxGetStaticModuleState());

at the top of the function. And besides, since the menu resource is loading fine, that seems to indicate that the module state is correct at least to some extent.

Can CXTPCommandBars::TrackPopupMenu be called anywhere or are there certain restrictions? I don't know what they would be, but...

Thanks,
Karim

Hello,

if AfxGetThread returns NULL it means that AfxGetApp will return NULL also. and this means something wrong with initialization/swiching MFC.
