[MFC] Close all popup modal dialog

關閉應用程式的時候需要順便把DoModal dialog一起順便關閉，不然應用程式會等待dialog的Close事件才會結束應用程式。

	void ClosePopupDialog()
	{
	HWND hWndParent = NULL;
	HWND hWndChild = ::GetWindow(this->m_hWnd, GW_ENABLEDPOPUP);
	if (hWndChild)
	{
	do
	{
	hWndParent = ::GetParent(hWndChild);
	CWnd *pWnd = CWnd::FromHandle(hWndChild);
	pWnd->EndModalLoop(0); // stop modal thread
	::EndDialog(hWndChild, 0); // close dialog
	hWndChild = hWndParent;
	} while (hWndParent != this->m_hWnd);
	}
	}
