Look in your Includes for GUIListView.au3

Use _GUICtrlListViewGetItemText and _GUICtrlListViewSetItemText. Remember that items are indexed starting at 0

Edit: You may have to save the text to a file then read it back later.

i cant seem to get it still. heres the script.

expandcollapse popup

#include <GUIConstants.au3>
#include <GuiListView.au3>

$d = GUICreate("Vehicle Statistics", 400,400,-1,-1)

$filemenu = GUICtrlCreateMenu("&File");
$addS = GUICtrlCreateMenuItem("&Add Data/Car...",$filemenu)
$deleteS = GUICtrlCreateMenuItem("&Delete Selected Item",$filemenu)
$save = GUICtrlCreateMenuItem("&Save Car Information",$filemenu)
    GUICtrlCreateMenuItem("",$filemenu)
$exit = GUICtrlCreateMenuItem("&Exit",$filemenu)
$listview = GUICtrlCreateListView("Statistics  /Make|Description  /Model",0,0,400,310,$LVS_EDITLABELS,$LVS_EX_HEADERDRAGDROP)
GUICtrlSendMsg($listview, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES)
GUICtrlSendMsg($listview, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT)
$item1=GUICtrlCreateListViewItem("Create a car first|Then delete this line",$listview)
$Input_3 = GUICtrlCreateInput("", 40,315,320,22)
GUICtrlSetState(-1,$GUI_DROPACCEPTED) 
$delete_button = GUICtrlCreateButton("Delete Selected Item", 40, 345,135,22)

GUISetState(@SW_SHOW)

$Label_4 = GuiCtrlCreateLabel("Description/Model", 200, 10, 160, 20)
$Button_5 = GuiCtrlCreateButton("Ok", 20, 70, 50, 20)
GUICtrlSetState(-1,$gui_focus)

If Not @error Then
            FileDelete($file);
            FileWrite($file, GUICtrlRead(GUICtrlRead($listview)));    
        EndIf

Change to

If Not @Error Then
   FileDelete($file)
   $Count = _GUICtrlListViewGetItemCount ( $listview )
   For $J = 0 To $Count -1
      FileWriteLine($File, _GUICtrlListViewGetItemText ( $h_listview, $J))
   Next
EndIf

This should do it as long as the ListViewItems do not already exist

$r_File = ''
_FileReadToArray($File, $r_File)
For $I = 1 To $r_File[0]
   _GUICtrlListViewInsertItem($listview,$I-1, $r_File[$I])
Next

EDIT:

I should have mentioned that _FileReadToArray() is in File.au3

If That's the only function that you are using from that UDF then just copy the function into your script because as I recall it doesn't require anything else. If you have a problem then #include <file.au3>

Here's another small change to your script

while 1
    $i = GUIGetMsg()
    $s_Count = _GUICtrlListViewGetSelectedCount ( $listview )
    If $s_Count < 1 Then
       If GUICtrlGetState($deleteS) <> 128 Then GUICtrlSetState($deleteS, 128)
    Else
       If GUICtrlGetState($deleteS) > 64 Then GUICtrlSetState($deleteS, 64)
    EndIf

That should make your "Delete selected item" MenuItem disabled if there is nothing selected.
