IOleInPlaceObjectWindowlessImpl::GetWindow

The container calls this function to get the window handle of the control.

HRESULT GetWindow( 
   HWND* phwnd  
);

Remarks

Some containers will not work with a control that has been windowless, even if it is currently windowed. In ATL's implementation, if the control class's data member m_bWasOnceWindowless is TRUE, the function returns E_FAIL. Otherwise, if phwnd is not NULL, GetWindow sets *phwnd to the control class's data member m_hWnd and returns S_OK.

See IOleWindow::GetWindow in the Windows SDK.
