    Public Sub OnAfterExportReport(Report: IPrxReport);
Begin
    //Call system event redetermined in Parent class
    Inherited OnAfterExportReport(Report);
End Sub OnAfterExportReport;
End Class EventsClass;
Public Class Parent: ReportEvents
    //Redetermine the EventOnBeforeExportReport system event
    Public Sub EventOnBeforeExportReport(Args: IUiPrxExportCancelEventArgs);
Begin
    //Handle system event
End Sub EventOnBeforeExportReport;
//Redetermine the EventOnAfterExportReport system event
