GUICtrlCreateEdit

Does anyone know of the best way to remove the last line in an edit control? I mean, if a user inputs:

Line 1

Line 2

Line 3

How do you remove "line 3" so the control only displays the first 2?

I have tried using StringInStr with StringMid and StringRight, just wondering if there is an easier way than going through every line?

I write a simple example to do what you want:

$GUI = GUICreate("TEST",200,170)
$EDIT = GUICtrlCreateEdit("LINE1" & @CRLF & "LINE2" & @CRLF & "LINE3",5,5,190,100)
$REMOVE = GUICtrlCreateButton("REMOVE LAST LINE",5,120,190,40)
GUISetState()

While 1
    $MSG = GUIGetMsg()
    If $MSG = $REMOVE Then
        $TEMP_DATA = GUICtrlRead($EDIT)
        $TEMP_DATA = StringSplit($TEMP_DATA,@CRLF)
        $NEW_DATA = ""
        For $INDEX = 1 To $TEMP_DATA[0]-1 Step 2
            If $INDEX = $TEMP_DATA[0]-2 Then
                $NEW_DATA &= $TEMP_DATA[$INDEX]
            Else
                $NEW_DATA &= $TEMP_DATA[$INDEX] & @CRLF
            EndIf
        Next
        GUICtrlSetData($EDIT,$NEW_DATA)
    ElseIf $MSG = -3 Then
        Exit
    EndIf
WEnd
