title: IAutoComplete custom source with IEnumString
body: <p>I am trying to implement auto-suggest for a comboxbox (win32, c++) or an edit-control. But I dont know how to use the interface IAutoComplete correctly. I need a custom list of strings where the matches for auto-suggest should be taken from. But how to implement this with IEnumString? I found this link but it doesnt reveal everything: <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/hh127437%28v=vs.85%29.aspx" rel="nofollow">http://msdn.microsoft.com/en-us/library/windows/desktop/hh127437%28v=vs.85%29.aspx</a></p>
  
  <p>Has anybody ever implemented this?
  Thx in advance
  Michael</p>
