VB后台工作者取消RunWorkerCompleted

Question

我想知道如果DoWork例程没有理由取消它，是否可以建议您取消RunWorkerCompleted例程。

Private Sub bgwNotifications_DoWork(ByVal sender As System.Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles bgwNotifications.DoWork

    'Do database Work to see if there are results

End Sub

Private Sub bgwNotifications_RunWorkerCompleted(ByVal sender As System.Object, ByVal e As System.ComponentModel.RunWorkerCompletedEventArgs) Handles bgwNotifications.RunWorkerCompleted

   'Show message based on results

End Sub`

此刻，我传递一个参数，如果该参数为0，则RunWorkerCompleted例程中不会执行任何代码。是这样还是在完全不运行RunWorkerCompleted例程的DoWork中取消选项？

谢谢您的帮助和建议。

德里克。
