Self closing Modeless dialog open from Modal Dialog switches Active Window in Windows.

Question

I have a Multiple document application.

From a menu / toolbar I open a Modal Dialog.

From this Modal Dialog , I open a Self Closing Modeless dialog.

Self Closing Modeless dialog : When the dialog is made inactive : handle WA_INACTIVE message : then I call DestroyWindow().

Thus the Modeless dialog gets auto destroyed.

After this focus does not again go in my Modal Dialog.

But, I observed that Active Window gets switched to another Window open in Windows.

I tried:

After destroying Self Closing Modeless dialog, I tried activating my Application window using AfxGetMainWnd.

		CWnd* pMainWnd = AfxGetMainWnd();
		pMainWnd->SetActiveWindow();

This helped me to avoid switching. But I am facing another issue is that My Modal Dialog is not in focus.

I tried setting Focus with SetFocus() method. But its of no use.

Please help me how can I activate & have focus in my Modal Dialog after auto destroying Modeless dialog.

I tried creating Self Closing Modeless dialog with

---

this->Create(MWPartImageOrientationDlg::IDD, pParent);

where pParent is the Modal Dialog.

---

I even tried

this->Create(MWPartImageOrientationDlg::IDD, AfxGetMainWnd());

---

But no benefit.

@David Lowndes had the right idea. Make the following change to your code and the focus will be properly returned to the button when the self-closing dialog is closed.

LRESULT My1ClosingDlg::OnActivate(WPARAM wParam, LPARAM lParam)
{
    WORD fActive = LOWORD(wParam);

    if (fActive == WA_INACTIVE)
    {
        /*DestroyWindow()*/PostMessage(WM_CLOSE);
    }
    return 0L;
}
