Hallo subzero007,
ich habe es gearde selbst getestet, so funktioniert es:
Spoiler anzeigen
[autoit]
#include <GUIConstantsEx.au3>
[/autoit] [autoit][/autoit] [autoit]#region ### START Koda GUI section ### Form=
$Form1 = GUICreate("Form1", 357, 166, 192, 124)
$ListView = GUICtrlCreateListView("Spalte1|Spalte2|Spalte3|Spalte4|Spalte5|Spalte6", 0, 0, 353, 135)
$LVItem = GUICtrlCreateListViewItem("1|2|3|4|5|6",$ListView)
$CheckIt = GUICtrlCreateButton("&Neu", 120, 140, 113)
GUISetState(@SW_SHOW)
#endregion ### END Koda GUI section ###
While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit
Case $CheckIt
GuiCtrlSetData($LVItem,"a|b|c| | | ")
EndSwitch
WEnd
