error: $WS_VSCROLL: undeclared global variable.

I'm getting this error:

(26,109) : warning: $WS_VSCROLL: possibly used before declaration.
Local $idComboBox = GUICtrlCreateCombo("", 2, 2, 296, 20, BitOR($CBS_DROPDOWN, $CBS_AUTOHSCROLL, $WS_VSCROLL)

Local $hGUI = GUICreate("Find Computer Owner", 300, 200)
; Create a combobox control.
Local $idComboBox = GUICtrlCreateCombo("", 2, 2, 296, 20, BitOR($CBS_DROPDOWN, $CBS_AUTOHSCROLL, $WS_VSCROLL))

Why do I do that?

You need to add

#include <WindowsConstants.au3>

to your script.
