Missing something on the "BeginQuit" event...

I've been trying to figure out how to use the "BeginQuit" event with little success. I'm a novice at VBA in AutoCad, so please don't go too fast!! I've tried to follow the instructions in the "VBA help", but seem to be missing something....

I've created a Class Module called "EventClassModule" and have the following code in it:

Public WithEvents ACADApp As AcadApplication
Public WithEvents AcadDocument As AcadDocument

I've put the tried the following code in both the "this drawing" object and a module called "module1":

Sub AcadApplication_Events()
' This example intializes the public variable (ACADApp) which will be used
' to intercept AcadApplication Events
'
' The VBA WithEvents statement makes it possible to intercept an generic object
' with the events associated with that object.
'
' Before you will be able to trigger any of the AcadApplication events,

' you will first need to run this procedure.

' We could get the application from the ThisDocument object, but that would
' require having a drawing open, so we grab it from the system.
Set ACADApp = GetObject(, "AutoCAD.Application")
End Sub
Private Sub ACADApp_BeginQuit(Cancel As Boolean)
' This example intercepts an Application BeginQuit event.

'
' This event is triggered when AutoCAD receives a request to shut down.
'
' To trigger this example event:
' 1) Make sure to run the example that initializes
' the public variable (named ACADApp) linked to this event.
'
' 2) Close the AutoCAD application

' Use the "Cancel" variable to stop the shut down of the application
If MsgBox("AutoCAD is about to shut down. Do you want to continue with the shutdown?", vbYesNoCancel + vbQuestion) <> vbYes Then

Cancel = True
End If
End Sub

It doesn't seem to work either way. the "AcadApplication_Events" sub says that "this has to be run first".....how do I do that? I suspect this may be my problem, but.....

Thanks in Advance!!!
