Ok, try the example below:

#include <GUIConstantsEx.au3>
#include <GuiListView.au3>
#include <WinAPI.au3>
#include <WindowsConstants.au3>

Global Const $clrWindowText = _WinAPI_GetSysColor($COLOR_WINDOWTEXT)
Global Const $clrWindow = _WinAPI_GetSysColor($COLOR_WINDOW)
Global $hForm, $hListView, $tRECT, $hDC

$tRECT = DllStructCreate($tagRect)
DllStructSetData($tRECT, "Left", 100)
DllStructSetData($tRECT, "Top", 100)
DllStructSetData($tRECT, "Right", 300)
DllStructSetData($tRECT, "Bottom", 250)

$Debug_LV = False ; Check ClassName being passed to ListView functions, set to True and use a handle to another control to see it work

_Main()

Func _Main()
    $hForm = GUICreate("ListView label example.", 640, 300)

    $hListView = GUICtrlCreateListView("", 2, 2, 636, 268)
    $hListView = GUICtrlGetHandle($hListView)

    ; Add columns
    _GUICtrlListView_AddColumn($hListView, "Filename", 340)
    _GUICtrlListView_AddColumn($hListView, "Filesize", 80)
    _GUICtrlListView_AddColumn($hListView, "Filetype", 100)
    _GUICtrlListView_AddColumn($hListView, "Last modified", 100)

    ; uncomment to view result!
    ;_GUICtrlListView_AddItem($hListView, "Row 1: Col 1", 0)

    GUISetState()

    $hDC = _WinAPI_GetDC($hListView)

    _WM_PAINT()
    GUIRegisterMsg($WM_PAINT, "_WM_PAINT")

    ; Loop until user exits
    Do
    Until GUIGetMsg() = $GUI_EVENT_CLOSE
    _Exit()

EndFunc   ;==>_Main

Func _WM_PAINT()

    Select
        Case Not _GUICtrlListView_GetItemCount($hListView)
            _WinAPI_UpdateWindow($hForm)
            _WinAPI_DrawText($hDC, "The list view is empty!", $tRECT, $DT_CENTER)
            _WinAPI_SetTextColor($hDC, $clrWindowText)
            _WinAPI_SetBkColor($hDC, $clrWindow)
            _WinAPI_SetBkMode($hDC, $TRANSPARENT)
    EndSelect

    Return 'GUI_RUNDEFMSG'
EndFunc   ;==>_WM_PAINT

Func _Exit()
    _WinAPI_ReleaseDC(0, $hDC)
    _WinAPI_InvalidateRect(0, 0)
    $tRECT = 0
    Exit
EndFunc   ;==>_Exit
