Deye 42 Posted March 28, 2016 was looking into adding a function that auto checks items on select using the example Here: it works but when I'm launching the GUI from a inside a function the GUIRegisterMsg wont kick in what i am missing here ? Thanks expandcollapse popup#include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <Array.au3> #include <GuiListView.au3> Global $listview _example() Func _example() Local $msg GUICreate("_example", 400, 300, -1, -1) Local $listview = GUICtrlCreateListView("Product ID|Category|Last Update", 2, 2, 394, 250) _GUICtrlListView_SetExtendedListViewStyle($listview, BitOR($LVS_EX_BORDERSELECT, $LVS_EX_FULLROWSELECT, $LVS_EX_CHECKBOXES, $LVS_EX_GRIDLINES)) GUISetState() GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") GUICtrlCreateListViewItem("1|2|3", $listview) GUICtrlCreateListViewItem("4|5|6", $listview) GUICtrlCreateListViewItem("7|8|9", $listview) While 1 $msg = GUIGetMsg() If $msg = $GUI_EVENT_CLOSE Then ExitLoop WEnd GUIDelete() EndFunc ;==>_example Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $iwParam Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $iCode = DllStructGetData($tNMHDR, "Code") If $iIDFrom = $listview Then Switch $iCode Case $NM_CLICK Local $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam) If @error Then Return $GUI_RUNDEFMSG Local $Item = DllStructGetData($tInfo, "Index") If @error Or $Item = -1 Then Return $GUI_RUNDEFMSG Local $tTest = DllStructCreate($tagLVHITTESTINFO) DllStructSetData($tTest, "X", DllStructGetData($tInfo, "X")) DllStructSetData($tTest, "Y", DllStructGetData($tInfo, "Y")) Local $iRet = GUICtrlSendMsg($iIDFrom, $LVM_HITTEST, 0, DllStructGetPtr($tTest)) If @error Or $iRet = -1 Then Return $GUI_RUNDEFMSG Switch DllStructGetData($tTest, "Flags") Case $LVHT_ONITEMICON, $LVHT_ONITEMLABEL, $LVHT_ONITEM If _GUICtrlListView_GetItemChecked($listview, $Item) = False Then _GUICtrlListView_SetItemChecked($listview, $Item, 1) Else _GUICtrlListView_SetItemChecked($listview, $Item, 0) EndIf Case $LVHT_ONITEMSTATEICON ;on checkbox EndSwitch EndSwitch EndIf Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY Share this post Link to post Share on other sites
AutoBert 183 Posted March 28, 2016 (edited) There is nothing missing. There is 1 Local to much. The 2. in line 12, after removing it the ControlID of the LV is assigned to Global $ListView (line 6) as needed. Edited March 28, 2016 by AutoBert 1 Share this post Link to post Share on other sites

Yep, as AutoBert says, you are declaring a Global variable $listview, but this is not actually assigned to the listview. it is just a blank global variable. You go on to create your GUI with a listview within the function as a Local variable (i.e. only used within the function). Hence why you are not getting any messages from the WM_NOTIFY function. Remove the "Local" and it will work as expected: $listview = GUICtrlCreateListView("Product ID|Category|Last Update", 2, 2, 394, 250) Edited April 21, 2016 by mpower Share this post Link to post Share on other sites
