You'll need to explain a little more, unless someone else can understand what you're asking.

faustf,

Do you mean that you only want to allow a single item in the ListView to be checked at any one time?

faustf,

This seems to work:

expandcollapse popup

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiListView.au3>

Global $iChecked = -1

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

$cLV = GUICtrlCreateListView("Column 0", 10, 10, 300, 300, BitOr($LVS_SHOWSELALWAYS, $LVS_SINGLESEL))
_GUICtrlListView_SetExtendedListViewStyle($cLV, BitOr($LVS_EX_FULLROWSELECT, $LVS_EX_CHECKBOXES, $LVS_EX_GRIDLINES))

For $i = 0 To 9
    GUICtrlCreateListViewItem("Item " & $i, $cLV)
Next

$cLVClicK_Dummy = GUICtrlCreateDummy()

GUISetState()

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

While 1
    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
        Case $cLVClicK_Dummy
            ; Read index of clicked item
            $iIndex = GUICtrlRead($cLVClicK_Dummy)
            ; Determine checked state
            Local $bState = _GUICtrlListView_GetItemChecked($cLV, $iIndex)
            ; If checked and not previous checked index
            If $bState And $iIndex <> $iChecked Then
                ; Clear old checked
                _GUICtrlListView_SetItemChecked($cLV, $iChecked, False)
                $iChecked = $iIndex
                ; Set new checked
                _GUICtrlListView_SetItemChecked($cLV, $iChecked)
            ; If not checked and was previously checked
            ElseIf Not ($bState) And $iIndex = $iChecked Then
                ; Clear check
                _GUICtrlListView_SetItemChecked($cLV, $iChecked, False)
                ; Set "No check" flag
                $iChecked = -1
            EndIf
    EndSwitch
WEnd

Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $iIDFrom = DllStructGetData($tNMHDR, "IDFrom")
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $iIDFrom
        Case $cLV ; It is our ListView
            Switch $iCode
                Case $NM_CLICK ; An item was clicked
                    $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam)
                    $iIndex = DllStructGetData($tInfo, "Index")
                    ; Action the dummy control and pass the row clicked
                    GUICtrlSendToDummy($cLVClicK_Dummy, $iIndex)
                    ; Select row if only checkbox actioned
                    _GUICtrlListView_SetItemState($cLV, $iIndex, $LVIS_SELECTED, $LVIS_SELECTED)
            EndSwitch
    EndSwitch
EndFunc
