Public WithEvents ACADApp As AcadApplication	' Use with Application Event Examples

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_BeginModal()
	' This example intercepts an Application BeginModal event.  We use a Beep instead of
	' a message box to notify the user when the event is triggered, since a message box
	' is a modal entity and would cause continuous BeginModal/EndModal events to be triggered.
	'
	' This event is triggered when AutoCAD displays a modal dialog.
	'
	' 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 begin a modal dialog operation.
	'	 For example, use AutoCAD to display a modal file dialog by using File/New

	Beep  ' A modal dialog is about to be displayed!
