Stuck on reading ListViewItems w/checkboxes

[drwoobie]

Hi all,

I am stuck trying to figure out how to get the contents of ListViewItems with checkbox controls (to pass on to other functions).

I've been looking at the forum, but I think I've confused myself even more.

Here's my testing code:

CODE

#NoTrayIcon

#include <GuiConstants.au3>

#include <ListViewConstants.au3>

; GUI

GuiCreate("list item select issue", 420, 400)

$currentView = GuiCtrlCreateListView("Col A | Col B", 5, 26, 203, 275, -1, BitOR( $LVS_EX_CHECKBOXES, $LVS_EX_FULLROWSELECT))

For $i = 1 To 3

GuiCtrlCreateListViewItem( "Item " & $i & "|" & "SubItem " & $i, $currentView)

Next

; BUTTON

$showMe = GuiCtrlCreateButton("Show Me", 5, 306, 65, 20)

; GUI MESSAGE LOOP

GuiSetState()

While 1

$msg = GUIGetMsg()

Select

Case $msg = $GUI_EVENT_CLOSE

ExitLoop

Case $msg = $showMe

MsgBox ( 4096, "Results", GUICtrlRead($currentView, 1))

EndSelect

WEnd

GUIDelete()

Exit

In all my testing of what I could find in the way of answers on the forum, the behavior of this code is the best result I have been able to manage.

Selecting a "line" item and clicking the button causes the msgbox to display (I assume) the line item's place value (1st line shows value "4") etc.

If I unselect a line and check a checkbox, the msgbox displays "0".

My goal is to be able to select a checkbox and sending the corresponding information to the next function.

What functions do I need to be looking at to get the functionality I want?

just a thing to point out...... when click the (show me button) your taking away the focus of the listview...

so to help you out...

Thank you aceguy. Your statement about the button taking the focus makes some very dim sense to me.

Just looking at that code block, I can tell I have some studying ahead of me.

Thanks for taking time to help me out.

your welcome Anytime and Welcome to Autoit

Just to point out, in order to use the button method, you could use a variable to save the last seleceted item, that way when you press the button, it reads from the $last_selected rather than the $listview. (if you really wanted the button method).
