Logman Posted March 16, 2008 Posted March 16, 2008 (edited) Hi, I have problem with $NM_DBLCLK handling for ListView. I need three forms:Form 1 = base form of appForm 2 = any listview with ListView event handlingForm 3 = viewing details of selected item from Form 2After double-click on a item in the listview AutoIt crashes!

Moderators SmOke_N Posted March 16, 2008 Moderators Posted March 16, 2008 (edited) You have all 3 gui's using $nMsg, what happens when you change each function to their own Var like $nMsg1 for $Form2 and $nMsg2 for $Form3? When using functions, you should really declare variables within the function local if they are only to be used in a local scope. Edit: Nah, I even changed that and it crashed still, even after changing up the wm_events... guess I'm too tired to debug:expandcollapse popup#include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <ListBoxConstants.au3> #include <WindowsConstants.au3> Global $Form1, $Form2, $Form3 Global $List_View Global $Result Global $hForm2 ; MAIN GUI $Form1=GUICreate("FORM 1", 600, 400) $Button1=GUICtrlCreateButton("Show form 2", 240, 352, 121, 33, 0) $Label1=GUICtrlCreateLabel("Text.....", 16, 16, 332, 17) GUISetState(@SW_SHOW,$Form1) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE ExitLoop Case $Button1 _ShowForm2($Form1) EndSwitch WEnd Exit ;== SHOW FORM 2 ============================== Func _ShowForm2($hParent) $Form2=GUICreate("FORM 2", 410, 250, Default, Default, -1, -1, $hParent) $Button2=GUICtrlCreateButton("Show form 3", 152, 200, 121, 33, 0) $List_View=GUICtrlCreateListView("Name", 8, 16, 393, 150) $item1=GuiCtrlCreateListViewItem("Paul",$List_View) $item2=GuiCtrlCreateListViewItem("Robert",$List_View) $item3=GuiCtrlCreateListViewItem("Chris",$List_View) Local $Label1=GUICtrlCreateLabel("Please, double click on a item...", 16, 170, 200, 17) GUISetState (@SW_DISABLE, $Form1) GUISetState(@SW_SHOW,$Form2) GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") ; <<<< SET EVENTS While 1 $nMsg2 = GUIGetMsg() Select Case $nMsg2 = $GUI_EVENT_CLOSE GUISetState (@SW_ENABLE, $Form1) GUIDelete($Form2) Return Case $nMsg2 = $Button2 _ShowForm3($Form2) ; test only EndSelect WEnd EndFunc ;==> SHOW FORM 2 ======================= ;== SHOW FORM 3 ============================== Func _ShowForm3($hParent) $Form3=GUICreate("FORM 3", 200, 100, Default, Default, -1, -1, $hParent) $Button3=GUICtrlCreateButton("Close", 48, 64, 97, 33, 0) $Result=GUICtrlCreateLabel("Result:", 16, 16, 100, 17) GUISetState(@SW_DISABLE,$Form2) GUISetState(@SW_SHOW,$Form3) While 1 $nMsg3 = GUIGetMsg() Select Case $nMsg3 = $GUI_EVENT_CLOSE Or $nMsg3 = $Button3 GUISetState (@SW_ENABLE, $Form2) GUIDelete($Form3) Return EndSelect WEnd EndFunc ;==> SHOW FORM 3 ======================= Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $iwParam Local $iCode, $tNMHDR $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $iCode = DllStructGetData($tNMHDR, "Code") Switch $iCode Case $NM_DBLCLK _ShowForm3($Form2) EndSwitch Return $GUI_RUNDEFMSG EndFunc Edited March 16, 2008 by SmOke_N Common sense plays a role in the basics of understanding AutoIt... If you're lacking in that, do us all a favor, and step away from the computer.
Logman Posted March 16, 2008 Author Posted March 16, 2008 Smoke_N, thanks for your reply. I've tried several times to change the wm_events, but still AutoIt crashes. I find it strange.

Logman Posted March 16, 2008 Author Posted March 16, 2008 Don't run the function from the WM_NOTIFY, just set a flag from there.You need to return from the WM_NOTIFY as quickly as possible.Huh, I think your solution is very simple and this is extremely useful information. You solved my problem, it's works!Thank you GaryFrost!
rasim Posted March 16, 2008 Posted March 16, 2008 GaryFrost Don't run the function from the WM_NOTIFY, just set a flag from there. You need to return from the WM_NOTIFY as quickly as possible.Well, but if i need run function from the WM_NOTIFY, possible run function and then exit from function with return? e.g.: Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo $hWndListView = $List_View If Not IsHWnd($List_View) Then $hWndListView = GUICtrlGetHandle($List_View) $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hWndListView Switch $iCode Case $NM_DBLCLK _ShowForm3() Return EndSwitch EndSwitch Return $GUI_RUNDEFMSG
GaryFrost Posted March 16, 2008 Posted March 16, 2008 Think about what this is doing..... WM_NOTIFY is fired Function is called from WM_NOTIFY that loads a new form New form is expecting WM_NOTIFY events but the function hasn't returned to WM_NOTIFY yet and WM_NOTIFY hasn't returned yet.
