PRB: Toolbar removed from Active Document in a frame in IE4

MORE INFORMATION

In order for the toolbar to reappear when the focus is set to the frame containing the Active Document, you must override CWnd::OnMouseActivate() in your CView-derived class and call COleServerDoc::ActivateInPlace().

Here is the code that is needed to override CWnd::OnMouseActivate().

MyView.h

   afx_msg int OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest,
                               UINT message);
				

MyView.cpp

   BEGIN_MESSAGE_MAP(CMyView, CView)
      ...
      ON_WM_MOUSEACTIVATE()
      ...
   END_MESSAGE_MAP()

   int CMyView::OnMouseActivate(CWnd* pDesktopWnd, UINT nHitTest,
                                UINT message)
   {
      COleServerDoc* pDoc = (COleServerDoc*)GetDocument();
      pDoc->ActivateInPlace();

      return CView::OnMouseActivate(pDesktopWnd, nHitTest, message);
   }
