Get index of the item selected from list box

[topgundcp]

Hi, 

This is my very first post in this forum and am also new with Autoit programming so be easy on me.

Below is the code that I am trying to get the index of the item selected. No problem getting the text.

Case $listEdition   ; handle of the list
            local $index=0
            $item=GUICTRLRead($listEdition)    ; This will return the text in the list
            ; ==============   The loop below always fails  ==================
            ; Meaning _GUICtrlListView_GetItemSelected($listEdition, $i) always return FALSE. WHY ???????
             For $i = 0 To $editionArray[0] - 1   ; The content of the list in an array where editionArray[0] contains total count of items
                If _GUICtrlListView_GetItemSelected($listEdition, $i) Then
                    $index = $i
                    exitloop
                EndIf
             Next
             ;===================================================
            ConsoleWrite( "Select Edition:     " & $item & "  index: " & $index & @CR)
.......

Please look at the comments in the code & the pix attached.

_GUICtrlListView_GetItemSelected($listEdition, $i) always returns FALSE.

Another problem is on the list. It also populate  the total count of items from the Array. How can I skip this item from populating to the list ?.

Please advise and thanks

what is 

$editionArray

[topgundcp]

EditionArray is  what you see on the list box. Take a look at  the picture where Edition[0] = 7 ie. the number of items on the list.

[alienclone]

i dont see where you define $editionArray 

your comment says editionArray contains the total count of items, but i dont see in your script where you tell it that.

@topgundcp You would help us in making a runable snippet of your code instead of showing us only a small part of the script.  You would get much more help that way.  Help us to help you...

@topgundcp: the function used doesn't seem to be the good one :

_GUICtrlListView_GetItemSelected()

As the title thread & the picture you posted indicate a list box (not a listview) then this instruction should be used instead :

_GUICtrlListBox_GetCurSel($listEdition)

Thank you guys.

As you can see I am quite new to this and this is my 2nd day learning Autoit so I am not familiar with all the functions available. Haven't done any programming in 15 years.

and thanks to @pixelsearch. I shall try and report back.

However, I play around and get it to work in a  dirty way by comparing the string in the Array and the text from the list, not really efficient though. and here's the code:

#include <ButtonConstants.au3>
#include <GUIConstantsEx.au3>
#include <GUIListBox.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>
#Region ### START Koda GUI section ### Form=J:\Autoit Projects\test.kxf
$TEST = GUICreate("TEST", 275, 310, -1, -1)
$Exit = GUICtrlCreateButton("Exit", 77, 240, 105, 33)
GUICtrlSetFont(-1, 9, 800, 0, "Arial Narrow")
$listEdition = GUICtrlCreateList("", 40, 48, 193, 160, BitOR($LBS_NOTIFY,$LBS_EXTENDEDSEL,$WS_VSCROLL))
$LEdit = GUICtrlCreateLabel("Windows 10 Edition", 40, 24, 119, 20)
GUICtrlSetFont(-1, 10, 400, 0, "Arial")
GUICtrlSetColor(-1, 0x000080)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

Next
$Lines = _ArrayToString($editionArray, "|", 1,Ubound($editionArray)-1, @CRLF)

                if StringCompare($item, $editionArray[$i]) = 0 Then
                    $index = $i
                    ExitLoop
                endif
            Next

Perfect. It works

Thank you.
