Horizontal scrollbar for list

[2000a]

I can't get an horizontal scrollbar on a list:

Global Const $WS_HSCROLL = 0x00100000

Global Const $WS_VSCROLL = 0x00200000

$mylist=GUICtrlCreateList ('my first item', 25, 50, 5, 250, $LBS_SORT+$WS_BORDER+$WS_VSCROLL+$WS_HSCROLL)

It creates a list box with a vertical scrollbar, but horizontal scroll bar... Anyone know how to add an horizontall scrollbar to a list?

thank you
