How can i detect when a user change a tab in my gui?

I have no succsess with testing the control ID.

...
$TabSheet3 = GUICtrlCreateTabItem("Contacts")
...
While 1
    $nMsg = GUIGetMsg()
    Select
            Case $nMsg = $TabSheet3
              _DoSomething

...

Will not work.

$Tab = GUICtrlCreateTabItem(10,10, 200,100)
$TabSheet3 = GUICtrlCreateTabItem("Contacts")
...
While 1
    $nMsg = GUIGetMsg()
    Select
            Case $nMsg = $Tab
               Switch GuiCtrlRead($Tab)
                  Case 0
                    _DoSomething
                  Case 1
                  Case 2
