Visual Basic now enables you to omit unused and unwanted arguments from your event handlers. The thought is that this makes for code that reads more cleanly. In addition, it enables you to assign methods directly to event handlers without trying to determine the proper event signature.
For example, suppose you had the following code to respond to a button click event.
Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click 'your code hereEnd Sub
You could remove the arguments from this code (or never put them in). Your new code functions the same and looks like this.
