Sending arguments to a context menu event handler

[Don Peters]

I can't seem to find an answer to this problem in spite of many searches.

I have a VB.NET program that has a context menu popup event. In it I
associate some menu items with their events, as follows:

ContextMenu1.MenuItems.Add("+1", New SystemEventHandler(AddressOf
Me.Plus1))
ContextMenu1.MenuItems.Add("+2", New SystemEventHandler(AddressOf
Me.Plus2))

So why not just pass address the same sub to each?

Should work fine.

Am I missing something here?

Yes, that's what I want to do. But when that Sub is called, it needs to know
who called it, e.g., what was the associated menu item. I'm wondering if I
somehow can get this info from Sub argument e.

That's what the sender property is for. You can cast the sender property
to a menu item and then look at the menu's caption to determine which one
was selected:

Private Sub MenuHandler(ByVal sender As Object, e As System.EventArgs)
Select Case DirectCast(sender, MenuItem).Text
Case "+1"
'Do something is +1 was selected
Case "+2"
'Do something is +2 was selected
End Select
End Sub

Ditto.

Chris is right. That is what I was going to say. Sender should give it to
you.
