Код:

;...
While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE, $Button1
            Exit
        Case $Button2
            $x = GUICtrlRead($Checkbox1)
            If $x = $GUI_CHECKED Then
                $x = 1
            Else
                $x = 0
            EndIf
            IniWrite($Dir, 'Section', 'Statistic', $x)
            Exit
    EndSwitch
