You just called AddHandler for the same button's Click event twice. Delete one of them. — Hans Passant, Mar 05 '14 at 10:40
ButtonOne.Click and firstButton.Click are two different buttons — Dolphin, Mar 05 '14 at 12:19
That's not what your complaint suggests. "One" and "first" are suspiciously similar of course. Picking good identifier names and avoiding storing a reference to an object in multiple variables are good ways to stay out of trouble. — Hans Passant, Mar 05 '14 at 12:40

As Hans pointed out.... you are calling the button click twice... Also see below

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
