[L3G3NdKillEr]

hi,

$PsList = GUICtrlCreateList("", 0, 0, 5, 410) 
GUICtrlSetData(-1, "item1|item2|item3")
GUICtrlSetOnEvent($PsList, "Psitems")

Func Psitems()
 $pics = GUICtrlRead($PsList)
    Switch $pics
        Case "item1"
           msgbox(1024, "" item1")

        Case "item2"
           msgbox(1024, "" item1")

        Case "item3"
           msgbox(1024, "" item1")
endswitch
endfunc
