BeginOpen Event - need an event that will execute whenever a drawing is opened

[jack.ryan]

I looked up the BeginOpen Event with Autocad VBA Help I got the code displayed below. Problem is the Example_AcadApplication_Events sub has to be executed before it will work. I need an event that will execute whenever a drawing is opened (even if ACAD is opened by double clicking a .dwg file.

Public WithEvents acadApp As AcadApplication

Sub Example_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.16")
End Sub

Private Sub ACADApp_BeginOpen(FileName As String)
    ' This example intercepts an Application BeginOpen event.
    '
    ' This event is triggered when a drawing is opened by AutoCAD.
    '
    ' To trigger this example event:
    '     1) Make sure to run the example that initializes
    '     the public variable (named ACADApp) linked to this event.
    '
    '     2) Use AutoCAD to open an existing drawing

    ' Use the "FileName" variable to determine which drawing file is being opened
    MsgBox "A drawing is about to be loaded from: " & FileName
End Sub
