Get list box items

[mattschinkel]

How do I get strings from a list box?

I am able to add strings with this:

ControlCommand ("MDSI", "", 1, "AddString", "string")

I am not able to use controlgettext.

Thanks,

Matt.

To use ControlCommand(), you would select each item in a loop with "SetCurrentSelection", and get its text with "GetCurrentSelection". The loop exits when selection fails:

#include <GuiConstantsEx.au3>

Global $hGUI, $ctrlButton, $ctrlLB
$hGUI = GUICreate("MDSI", 300, 300)
$ctrlLB = GUICtrlCreateList("Item 0", 20, 20, 260, 210)
For $n = 1 To 19
    GUICtrlSetData($ctrlLB, "Item " & $n)
Next
$ctrlButton = GUICtrlCreateButton("READ", 100, 250, 100, 30)
GUISetState()

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $ctrlButton
            _ReadItems()
    EndSwitch
WEnd

Func _ReadItems()
    Local $n = 0, $sTxt = "", $sMsg = ""
    While 1
        ControlCommand("MDSI", "", $ctrlLB, "SetCurrentSelection", $n)
        If @error Then ExitLoop ; Done
        $sTxt = ControlCommand("MDSI", "", $ctrlLB, "GetCurrentSelection", "")
        $sMsg &= $n & ":  " & $sTxt & @CRLF
        $n += 1
    WEnd
    MsgBox(64, "Result", $sMsg)
EndFunc   ;==>_ReadItems

There are more advanced UDF functions that can get the count and read the items without selecting each one, like _GUICtrlListBox_GetCount() and _GUICtrlListBox_GetText():

#include <GuiListBox.au3>

; Rest of script body is the same...

Func _ReadItems()
    Local $hLB = ControlGetHandle("MDSI", "", $ctrlLB)
    Local $iCnt = _GUICtrlListBox_GetCount($hLB)
    Local $sMsg = ""
    For $n = 0 To $iCnt - 1
        $sMsg &= $n & ":  " & _GUICtrlListBox_GetText($hLB, $n) & @CRLF
    Next
    MsgBox(64, "Result", $sMsg)
EndFunc   ;==>_ReadItems

The 2nd example works great thanks. Maybe this should be added to the Autoit releases since there is currently no command for retrieving text from list boxes in external programs.
