显示模式对话框时不会触发任何事件。

例子

VBA：

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.22")
End Sub

Private Sub ACADApp_NewDrawing()
    ' This example intercepts an Application NewDrawing event.
    '
    ' This event is triggered when a new drawing request is sent to 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 create a new drawing using File/New

    MsgBox "A request to start a new drawing was just intercepted!"
End Sub
