maniootek 5 Posted April 13, 2016 (edited) What would be a best method to reduce CPU/memory usage to read index of clicked item from ListView? I have modified example script from help file and my current code is: expandcollapse popup#include <GUIConstantsEx.au3> ;$GUI_EVENT_CLOSE #include <GuiListView.au3> #include <WindowsConstants.au3> ;$WM_NOTIFY Global $g_hListView Example() Func Example() Local $hGUI, $hImage $hGUI = GUICreate("(UDF Created) ListView Create", 400, 300) $g_hListView = _GUICtrlListView_Create($hGUI, "", 2, 2, 394, 268) _GUICtrlListView_SetExtendedListViewStyle($g_hListView, BitOR($LVS_EX_GRIDLINES, $LVS_EX_FULLROWSELECT, $LVS_EX_SUBITEMIMAGES)) GUISetState(@SW_SHOW) GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") ; Add columns _GUICtrlListView_InsertColumn($g_hListView, 0, "Column 1", 100) _GUICtrlListView_InsertColumn($g_hListView, 1, "Column 2", 100) _GUICtrlListView_InsertColumn($g_hListView, 2, "Column 3", 100) ; Add items _GUICtrlListView_AddItem($g_hListView, "Row 1: Col 1") _GUICtrlListView_AddSubItem($g_hListView, 0, "Row 1: Col 2", 1) _GUICtrlListView_AddSubItem($g_hListView, 0, "Row 1: Col 3", 2) _GUICtrlListView_AddItem($g_hListView, "Row 2: Col 1") _GUICtrlListView_AddSubItem($g_hListView, 1, "Row 2: Col 2", 1) _GUICtrlListView_AddItem($g_hListView, "Row 3: Col 1") ; Loop until the user exits. Do Until GUIGetMsg() = $GUI_EVENT_CLOSE GUIDelete() EndFunc ;==>Example Func WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam) #forceref $hWnd, $iMsg, $wParam Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo ; Local $tBuffer $hWndListView = $g_hListView If Not IsHWnd($g_hListView) Then $hWndListView = GUICtrlGetHandle($g_hListView) $tNMHDR = DllStructCreate($tagNMHDR, $lParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hWndListView Switch $iCode Case $NM_CLICK ; Sent by a list-view control when the user clicks an item with the left mouse button $tInfo = DllStructCreate($tagNMITEMACTIVATE, $lParam) $index = DllStructGetData($tInfo, "Index") MsgBox(0,0,$index) EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY other method is to check in a loop if new item was selected via _GUICtrlListView_GetItemSelected() expandcollapse popup#include <GUIConstantsEx.au3> ;$GUI_EVENT_CLOSE #include <GuiListView.au3> Example() Func Example() Local $idListview Local $last_selected_item_index = -1 GUICreate("ListView Get Item Selected", 400, 300) $idListview = GUICtrlCreateListView("", 2, 2, 394, 268) GUISetState(@SW_SHOW) ; Add columns _GUICtrlListView_AddColumn($idListview, "Items", 100) ; Add items _GUICtrlListView_AddItem($idListview, "Item 1") _GUICtrlListView_AddItem($idListview, "Item 2") _GUICtrlListView_AddItem($idListview, "Item 3") ; Loop until the user exits. Do $iCount = _GUICtrlListView_GetItemCount($idListview) For $i = 0 To $iCount - 1 If _GUICtrlListView_GetItemSelected($idListview, $i) Then $now_selected_item_index = $i If $last_selected_item_index <> $now_selected_item_index Then MsgBox(0, 0, $now_selected_item_index) $last_selected_item_index = $now_selected_item_index ContinueLoop EndIf EndIf Next Until GUIGetMsg() = $GUI_EVENT_CLOSE GUIDelete() EndFunc ;==>Example which one is better?

maniootek 5 Posted April 13, 2016 (edited) Ok thanks for answer. Anyway, I have tried to add _GUITreeViewEx_RegMsg() from @Melba23 TreeViewEx UDF together with my first example byt unfortunatelly they don't work together (only one which was defined in code as the last one). I am new with this type of "GUIRegisterMsg" and I don't know why only one working at time. Is there some limitation to use only one RegisterMsg? First example also crash my _ArrayDisplay function so I am staying away of this solution. Second example cause no erorrs.

AFAIK you can only register a MSG ID to a single function...however you could write a notify function that would handle all of the controls/events you need. How I might approach it would be to copy the notification function from the GUITreeViewEX UDF (_GUITreeViewEx_WM_NOTIFY_Handler) to a new Notify function (i.e. _WM_NOTIFY), register the event yourself and add the functionality you need to it. Just for an example, in this script I made I use a custom _WM_NOTIFY function to handle multiple controls on different GUIs.
