[2008] Friend WithEvents

[zhshqzyc]

Hello,

If I drag a button to the form, when the user clicks the button to fire an event.

The code looks like

Private Sub button1_Click(ByVal sender As System.Object,_
    ByVal e As System.EventArgs) Handles button1.Click
    text1.Text = "Hello World!"
End Sub

It's very short and simple.
My question is shall I define the button as

Friend WithEvents button1 As Button

I haven't defined it but it works well.

I saw some books define it.
Is it unnecessary?

Thanks for your time.

The designer automatically does that for you. In 2005 it is in the Form.Designer.vb file. I don't have 2008 on this machine, so it might be a little different, but that code is there.

In Solution Explorer, click on the 'show all files' icon if all the files aren't already showing. You should see a Form1.designer.vb file in there. Open it up and have a look.
