Invalidate Object Moved by Server

The framework calls COleClientItem::OnChangeItemPosition whenever the server requests a change in the position of the in-place activated object. This is one of several occasions for which you can implement smart repainting.

To send an update hint when the position of the CContainerItem object changes

• Use ClassView to jump to the implementation of CContainerItem::OnChangeItemPosition and replace the following code:

  GetDocument()->UpdateAllViews(NULL);
  m_rect = rectPos;
  

  with this code:

  InvalidateItem();
  m_rect = rectPos;
  InvalidateItem();
