title: What are DShellFolderViewEvents and DShellFolderViewEvents_Event?
body: <p>The names make it sound like some sort of event handler.<br>
  Both were identified as an interface from <code>Shell32</code> using the code below: 
  I can't find either of these in the MSDN libraries.  Google returned some pages with code where they appeared, but I didn't see anything that really described the interface.  </p>
  
  <pre><code>Public Sub ListTypes()
      Dim NS As String = "Shell32"
      For Each t As Type In Assembly.GetExecutingAssembly().GetTypes()
          If (t.IsClass Or t.IsInterface) And t.Namespace = NS Then
              Debug.Print(t.Name)
          End If
      Next
  End Sub 
  </code></pre>
