Sub AddInExample()
   ' For this example to work correctly, there should be an add-in 
   ' available in the Visual Studio environment.
   ' Set object references.
   Dim addincoll As AddIns
   Dim addinobj As AddIn
   
   ' Register an add-in, check DTE Add-in count before and after the 
   ' Update.
   addincoll = DTE.AddIns
   MsgBox("AddIns collection parent name: " & addincoll.Parent.Name)
   MsgBox("Number of Add-ins: " & addincoll.Count)
   ' NOTE: Use regsvr32 for Visual C++, regasm for Visual Basic 
   ' and Visual C#. Also, the pathname used below is an example only.
   Shell("regasm F:\AddIns\RegExplore\Debug\regexplore.dll")
   addincoll.Update()
   MsgBox("Number of Add-ins: " & addincoll.Count)
   addinobj = addincoll.Item(1)

   ' Connect the add-in if it is not already connected
   ' and list its SatelliteDLLPath and Guid.
   If addinobj.Connected = False Then
      addinobj.Connected = True
   End If
   MsgBox("Satellite DLL Path: " & addinobj.SatelliteDllPath)
   MsgBox("DLL GUID: " & addinobj.Guid)

   ' Activates a solution add-in so that it is available, then 
...' deactivates it.
   addinobj = DTE.Solution.AddIns.Add(addinobj.ProgID, addinobj.Description, addinobj.Name, False)
   DTE.Solution.AddIns.Item(1).Remove()
