title: CVSListBox notification after delete
body: <p>I've just added one of the new (MFC Feature Pack) CVSListBox controls to a project.  The list of items in the control is tracked by some other objects in my application, so I need to take lots of notifications from the list-box when anything changes so that I can update other stuff.  For those that don't know the control, there is a button bar which offers basic add/delete/reorder functionality.</p>
  
  <p>The CVSListBox control offers overridable virtual functions for things like adding or renaming items, and changing their order - all this works nicely.</p>
  
  <p>However, for deleting items, the only override is OnBeforeRemoveItem, which is called BEFORE an item is removed, and from which one has to return TRUE/FALSE to permit the remove.  Once the remove has occurred, there's no specific notification.</p>
  
  <p>What's the best way to get notification AFTER a remove?</p>
  
  <p>Obviously it's possible to hack something horrible here, in that there will be a selection-changed event after a remove, and it would be possible to hold a flag from the before-remove to say that the next selection-changed is special.  But I feel like I'm missing something cleaner and more obvious.  Any suggestions?</p>
