; Changing MsgBox's Button Names
; https://www.autohotkey.com
; This is a working example script that uses a timer to change
; the names of the buttons in a message box. Although the button
; names are changed, the MsgBox's return value still requires that the
; buttons be referred to by their original names.

#SingleInstance
SetTimer ChangeButtonNames, 50
Result := MsgBox("Choose a button:", "Add or Delete", 4)
if Result = "Yes"
    MsgBox "You chose Add."
else
    MsgBox "You chose Delete."

ChangeButtonNames()
{
    if !WinExist("Add or Delete")
        return  ; Keep waiting.
    SetTimer , 0
    WinActivate
    ControlSetText "&Add", "Button1"
    ControlSetText "&Delete", "Button2"
}
