hot202,

I do not believe that is possible. :)

However, as it is really easy to set the data in a combo, you can easily remove/reinsert the item you do not want. Here is a short example where a single item is removed from and then reinserted in the list.

#include <GUIConstantsEx.au3>

Global $aArray[4] = ["zero", "one", "two", "three"]

$hGUI = GUICreate("Test", 500, 500)

$hCombo = GUICtrlCreateCombo("", 10, 10, 200, 20)
_Load_Combo()

GUISetState()

Sleep(5000)

ConsoleWrite("Removing two" & @CRLF)
_Load_Combo(2)

Sleep(5000)

ConsoleWrite("Reinserting two" & @CRLF)
_Load_Combo()

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

Func _Load_Combo($iIndex = -1)

    Local $sString = "|"
    For $i = 0 To UBound($aArray) - 1
        If $i <> $iIndex Then $sString &= $aArray[$i] & "|"
    Next
    GUICtrlSetData($hCombo, $sString)

EndFunc

I hope it helps. :(

Using HTML it is possible to disable certain lines in the combo box on the web. This makes showing trees like

Root
  Branch_#_1
   -leaf
   -leaf
   -leaf
  Branch_#_2
   -leaf
   -leaf

possible, and only allowing the user to select the leafs. Are we to believe that a browser can create a control on a webpage better than AutoIt? :)

Creating 'unselectable' lines really helps with the organization of long combo lists. Perhaps AutoIt v4 will have this.
