dragan Posted December 9, 2012 Share Posted December 9, 2012 I am getting my script crashed if I use functions like WM_NOTIFY for listview + cmd function + reading it when resizing the listview column. While this example script is running, try to resize listview's column, hold on the column size-bar for some time, resize both, forward and backward, you'll see that the script will crash. Why is that? expandcollapse popup#include <GUIConstantsEx.au3> #include <WindowsConstants.au3> #include <GuiListView.au3> #include <Constants.au3> $Form1 = GUICreate("Form1", 500, 400) $List1 = GUICtrlCreateListView("col 1|col 2|col 3|col 4|col 5", 0, 0, 500, 400) For $i = 0 to 4 _GUICtrlListView_SetColumnWidth($List1, $i, 95) Next GUISetState(@SW_SHOW) GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") AdlibRegister("updatelist", 2000) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd Func updatelist() if _GUICtrlListView_GetItemCount($List1) >= 10 Then For $i = 0 to Random(2, 4, 1) _GUICtrlListView_DeleteItem($List1, $i) Next Else For $i = 1 to Random(1, 3, 1) GUICtrlCreateListViewItem("data1data1data1|data2data2data2|data3data3data3|data4data4data4|data5data5data5", $List1) Next EndIf Local $iPID = Run(@ComSpec & ' /c netstat -nao', @SystemDir, @SW_HIDE, $STDOUT_CHILD + $STDERR_CHILD) if @error then Return SetError(3, 0, 0) Local $sOutput While 1 $sOutput &= StdoutRead($iPID) If @error Then ExitLoop EndIf Sleep(100) WEnd ConsoleWrite($sOutput & @LF) EndFunc Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView $hWndListView = $List1 If Not IsHWnd($List1) Then $hWndListView = GUICtrlGetHandle($List1) $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hWndListView Switch $iCode Case $NM_CUSTOMDRAW ; randomly chosen function, the more functions there are = the more chance you get crash Local $tCustDraw = DllStructCreate($tagNMLVCUSTOMDRAW, $ilParam) Local $iDrawStage = DllStructGetData($tCustDraw, "dwDrawStage") Switch $iDrawStage Case $CDDS_PREPAINT Return $CDRF_NOTIFYITEMDRAW Case $CDDS_ITEMPREPAINT Return $CDRF_NOTIFYSUBITEMDRAW EndSwitch Local $iSubItem = DllStructGetData($tCustDraw, "iSubItem") If $iSubItem = 4 Then DllStructSetData($tCustDraw, "clrText", 0x038507) Return $CDRF_NEWFONT EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY Link to comment Share on other sites More sharing options...
BrewManNH Posted December 9, 2012 Share Posted December 9, 2012 The script isn't crashing it's getting stuck in the WM_NOTIFY function. Figure out what is causing it to lock up in there and then prevent it. If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.Give a programmer the correct code and he can do his work for a day.

dragan Posted December 9, 2012 Author Share Posted December 9, 2012 I did try, many things in my original script and when I failed I created this example script just to ask about this issue on forum. I'm clueless why is it halting in WM_NOTIFY.. Link to comment Share on other sites More sharing options...
kylomas Posted December 9, 2012 Share Posted December 9, 2012 dragan, Have you tried disabling the random updates from the adlib? This may be colliding with the notification routine. kylomas Forum Rules Procedure for posting code "I like pigs. Dogs look up to us. Cats look down on us.

dragan Posted December 9, 2012 Author Share Posted December 9, 2012 I need the updates, in my original script my list gets updated constantly, I just simulated those update via adlib in this example. Link to comment Share on other sites More sharing options...
dragan Posted December 9, 2012 Author Share Posted December 9, 2012 (edited) Maybe if I could block the resizing of columns? Could it be done? I've read that WM_NOTIFY could hook $HDN_BEGINTRACK and set _WinAPI_SetWindowLong to DWL_MSGRESULT (value = 0), but I wasn't successful:... Case $HDN_BEGINTRACK ConsoleWrite("I got it!"& @LF) _WinAPI_SetWindowLong($hWnd, 0, true); Return true ...p.s. it's listview related, not header Edited December 9, 2012 by dragan Link to comment Share on other sites More sharing options...
Moderators Melba23 Posted December 9, 2012 Moderators Share Posted December 9, 2012 dragan, I show how to prevent ListView column resizing here. Plus if you only want to fix the size of specific columns then you can do so like this from later in the same thread.
