Real beginner question

G222 · December 26th, 2009, 05:25 AM

I am just starting to use VS 2008, Visual Basic. When I double click a button I get a procedure like:

Code:

     Private Sub mnuFilePrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuFilePrint.Click
           End Sub

Now if I want to make a call to this procedure what do I use for arguments?

I have tried

Code:

 Private Sub cmdPrintResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdPrintResults.Click
        mnuFilePrint_Click()
    End Sub

but I get a error messages like

"argument not specified for parameter 'e' of . . . "
and "argument not specified for parameter 'sender' of . . . "

Please help

Hi there,

You typically don't call these event handlers directly as they are designed to handle a specific event (e.g. a Button's Click) called by the runtime or based on some user action. Instead, you can create a method that contains the code you typically have in the handler and call that method instead. E.g.:

Code:

 
Private Sub mnuFilePrint_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuFilePrint.Click
  PrintStuff()
End Sub
 
Private Sub cmdPrintResults_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdPrintResults.Click
  PrintStuff()
End Sub
 
Private Sub PrintStuff()
  ' Do here what you previously did in mnuFilePrint_Click
End Sub

Hope this helps,

Imar
