事件发射两次

Question

我在vb.net处理事件

 AddHandler ButtonOne.Click, AddressOf ButtonClick

 Private Sub ButtonClick(ByVal ctrl As Office.CommandBarButton, ByRef Cancel As Boolean)
    //do stuff
 End sub

但是我的事件要求两次。当我点击按钮时，也会在另一种方法中点击 我正在处理同样的事件

   Private Sub AddToolbar()
   // do something
     AddHandler firstButton.Click, AddressOf ButtonClick
   End 

如何解决此问题？ 请帮助我

正如汉斯指出的那样....你打电话给按钮点击两次......另见

AddHandler ButtonOne.Click, AddressOf ButtonClick 'You dont really need this if you add a handler to the sub see below...

 Private Sub ButtonClick(ByVal ctrl As Office.CommandBarButton, ByRef Cancel As Boolean) Handles ButtonOne.Click
    //do stuff
 End sub
