Problems with IProgressDialog

[Barry True]

I have an application that uses the IProgressDialog interface to dislay a progress dialog during long processing steps. Everything works fine until I invoke the StopProgressDialog method to close the dialog. The progress dialog doesn't disappear until I move the mouse over it. Does anyone know what could be causing this?

Did you ever figure out the solution? I am having the exact same issue.

It's been a while since I had this problem but I believe what we ended up doing was to get the window handle of the dialog and force it down. I no longer have access to the code but if I can find out from a person who's still working on the project I'll try to post the code we used.

After searching the internet some more I found the same answer. Following is the code, in case anyone else has this issue. HWND hDlgWnd(NULL); HRESULT hr; IOleWindow *pOleWindow; //Sometimes the progress dialog sticks around after stopping it, //until the mouse pointer is moved over it or some other triggers. //This process finds the hwnd of the progress dialog and hides it //immediately. if (SUCCEEDED(m_pprogressdlg->QueryInterface(IID_IOleWindow, reinterpret_cast (&pOleWindow)))) { hr = pOleWindow->GetWindow(&hDlgWnd); if(FAILED(hr)) { hDlgWnd = NULL; } pOleWindow->Release(); } m_pprogressdlg->StopProgressDialog(); if (hDlgWnd) ::ShowWindow(hDlgWnd, SW_HIDE); m_pprogressdlg.Release();

As I recall, that's basically what we did as well. I'll double-check this when I can get the code fragment from my co-worker.
