End Sub

Private Sub IDTExtensibility2_OnConnection(ByVal Application As Object, ByVal ConnectMode As AddInDesignerObjects.ext_ConnectMode, ByVal AddInInst As Object, custom() As Variant)
' Occurs when the COM add-in is connected.
' The Application argument is the Outlook Application object.
' The ConnectMode argument specifies how the COM add-in was connected.
' It can be
'     ext_cm_AfterStartup     Add-in was connected after Outlook started,
'                             or the Connect property of the corresponding
'                             COMAddIn object was set to True
'     ext_cm_Startup          Add-in was connected on startup

' The AddInInst argument is the COMAddIn object that refers to the current
'     instance of the add-in itself.

End Sub

Private Sub IDTExtensibility2_OnDisconnection(ByVal RemoveMode As AddInDesignerObjects.ext_DisconnectMode, custom() As Variant)
' Occurs when the COM add-in is disconnected.

' It can be
'     ext_dm_HostShutdown      Add-in was disconnected when Outlook was
'                              closed.
'     ext_dm_UserClosed        Add-in was disconnected when the user

'                              object was set to False.
' The custom argument is ignored.
End Sub

Private Sub IDTExtensibility2_OnStartupComplete(custom() As Variant)
' If the COM add-in connects at startup, occurs when Outlook completes
' its startup routines. This event does not occur if the COM add-in is not

' the COM Add-ins dialog box.
