enaiman Posted March 22, 2011 Share Posted March 22, 2011 (edited) I don't know if this is a bug or not but if I am using WM_NOTIFY to detect a double click on a listView item, any further call for _ArrayDisplay it will make the _ArrayDisplay GUI to freeze. I have put together an example script: expandcollapse popup#AutoIt3Wrapper_au3check_parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 #include <GuiConstantsEx.au3> #include <GuiListView.au3> #include <WindowsConstants.au3> Opt('MustDeclareVars', 1) Opt("GUIOnEventMode", 1) Global $hListView Global $ListContent Global $TestARR[4] = ["test1", "test2", "test3", "test4"] GUICreate("ListView", 400, 300) GUISetOnEvent($GUI_EVENT_CLOSE, "Form1Close") $hListView = GUICtrlCreateListView("col1|col2|col3", 2, 2, 394, 268) GUICtrlSendMsg($hListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES) GUICtrlSendMsg($hListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT) GUICtrlCreateListViewItem("line4|5|more_a", $hListView) GUICtrlCreateListViewItem("line5|4.50 |more_c", $hListView) GUICtrlCreateListViewItem("line5|4.0 |more_c", $hListView) GUICtrlCreateListViewItem("line3|23|more_e", $hListView) GUICtrlCreateListViewItem("line2|0.34560 |more_d", $hListView) GUICtrlCreateListViewItem("line1|1.0 |more_b", $hListView) GUICtrlCreateListViewItem("line1|0.1 |more_b", $hListView) GUICtrlCreateListViewItem("line1|10|more_b", $hListView) _GUICtrlListView_SetColumnWidth($hListView, 0, 75) _GUICtrlListView_SetColumnWidth($hListView, 1, 75) _GUICtrlListView_SetColumnWidth($hListView, 2, 75) GUISetState() GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") While 1 Sleep(200) WEnd Func Form1Close() Exit EndFunc Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $iwParam Local $hWndFrom, $iIDFrom, $iCode, $tNMHDR, $hWndListView, $tInfo ;~ Local $tBuffer $hWndListView = $hListView If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView) $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iIDFrom = DllStructGetData($tNMHDR, "IDFrom") $iCode = DllStructGetData($tNMHDR, "Code") Switch $hWndFrom Case $hWndListView Switch $iCode Case $NM_DBLCLK ; Sent by a list-view control when the user double-clicks an item with the left mouse button $tInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam) MsgBox(0, "DoubleClick", "Double Click detected") _ArrayDisplay($TestARR) EndSwitch EndSwitch Return $GUI_RUNDEFMSG EndFunc ;==>WM_NOTIFY For me the GUI freezes and all I can do is to close the application. AutoIt 3.3.6.1 and Win7 It is really strange - does anyone have an idea why this is happening? Am I doing something wrong?

guinness Posted March 22, 2011 Share Posted March 22, 2011 (edited) I tidied up the code a little ... It's never a good idea to interrupt the WM Message with a MsgBox() or _ArrayDisplay() (for example.) You can see that I have recorded the Item and SubItem and then set a Global variable to indicate there was a DoubleClick, from there the WM Message is exited and the MsgBox() + _ArrayDisplay() is shown.expandcollapse popup#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6 #include <GuiConstantsEx.au3> #include <GuiListView.au3> #include <WindowsConstants.au3> Opt('MustDeclareVars', 1) Opt("GUIOnEventMode", 1) Global $hListView, $iDoubleClick = 0 Global $ListContent Global $TestARR[4] = ["test1", "test2", "test3", "test4"] GUICreate("ListView", 400, 300) GUISetOnEvent($GUI_EVENT_CLOSE, "Form1Close") $hListView = GUICtrlCreateListView("col1|col2|col3", 2, 2, 394, 268) GUICtrlSendMsg($hListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_GRIDLINES, $LVS_EX_GRIDLINES) GUICtrlSendMsg($hListView, $LVM_SETEXTENDEDLISTVIEWSTYLE, $LVS_EX_FULLROWSELECT, $LVS_EX_FULLROWSELECT) GUICtrlCreateListViewItem("line4|5|more_a", $hListView) GUICtrlCreateListViewItem("line5|4.50 |more_c", $hListView) GUICtrlCreateListViewItem("line5|4.0 |more_c", $hListView) GUICtrlCreateListViewItem("line3|23|more_e", $hListView) GUICtrlCreateListViewItem("line2|0.34560 |more_d", $hListView) GUICtrlCreateListViewItem("line1|1.0 |more_b", $hListView) GUICtrlCreateListViewItem("line1|0.1 |more_b", $hListView) GUICtrlCreateListViewItem("line1|10|more_b", $hListView) _GUICtrlListView_SetColumnWidth($hListView, 0, 75) _GUICtrlListView_SetColumnWidth($hListView, 1, 75) _GUICtrlListView_SetColumnWidth($hListView, 2, 75) GUISetState() GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY") While 1 If $iDoubleClick = 1 Then MsgBox(0, "DoubleClick", "Double Click detected") _ArrayDisplay($TestARR) $iDoubleClick = 0 EndIf Sleep(200) WEnd Func Form1Close() Exit EndFunc ;==>Form1Close Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam) #forceref $hWnd, $iMsg, $iwParam Local $hWndFrom, $iCode, $tNMHDR, $hWndListView, $iInfo, $iIndex, $iSubItem $hWndListView = $hListView If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView) $tNMHDR = DllStructCreate($tagNMHDR, $ilParam) $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom")) $iCode = DllStructGetData($tNMHDR, "Code") $iInfo = DllStructCreate($tagNMITEMACTIVATE, $ilParam) $iIndex = DllStructGetData($iInfo, "Index") ; The 'Row' Number Selected E.G.

AdmiralAlkex Posted March 22, 2011 Share Posted March 22, 2011 The helpfile tell you something very important for GUIRegisterMsg() =Warning: blocking of running user functions which executes window messages with commands such as "Msgbox()" can lead to unexpected behavior, the return to the system should be as fast as possible !!!Remember that AutoIt can only do one event at a time, others are put to a queue, so when you use a blocking function things just break down. Like putting a mountain in front of a train.KABOOM!! .Some of my scripts: ShiftER, Codec-Control, Resolution switcher for HTC ShiftSome of my UDFs: SDL UDF, SetDefaultDllDirectories, Converting GDI+ Bitmap/Image to SDL Surface Link to comment Share on other sites More sharing options...
enaiman Posted March 22, 2011 Author Share Posted March 22, 2011 @guinness Thank you very much for clarifying this aspect. That Melba23 quote really sounded familiar, at some point in the past I definitely read about that but I forgot It is obviously my poor coding's fault here - in my big script I was calling a function when a double-click was detected ... well I can see clearly now from your example how it needs to be done. Lesson learned - I am pretty sure I won't forget it SNMP_UDF ... for SNMPv1 and v2c so far, GetBulk and a new example script wannabe "Unbeatable" Tic-Tac-Toe Paper-Scissor-Rock ... try to beat it anyway :) Link to comment Share on other sites More sharing options...
