I've been researching this topic for about three weeks, but I'm still very confused. What I'm trying to do is to add a menu item to an arbitrary, third- party applications title bar system menu and process user events relating to it. The main problem I'm having is that there appears to be a wealth of UDFs and other techniques to accomplish this, and I can't figure out which to concentrate on as a good solution. For example, I've looked closely at @BrewManNHB 's GUIRegisterMsg replacement for GUICtrlSetOnEvent and GUIGetMsg, and @LarsJJ 's stunning product GUIRegisterMsg20 UDF, as well as standard build- in AutoIt functions and WinAPI functions, But before I ask for recommendations, I'll elaborate my needs in more detail... I'm nearing completion of my muilt-monitor UDF and AutoWinSwitch stand-alone application, but one tricky issue remains. The purpose of the application is to automatically move newly arisen windows and context menus and the like from a monitor which is being used for some other purpose (like playing a game or watching videos) to the other monitor so that the user can see them and act upon them. The feature I need all this for is to allow the user to prevent a user-designated window from being moved, even though it exists on the "blocked" or used monitor so that it would normally require moving. In my testing, I've run into this situation often enough that a solution is necessary. So what I've done so far is to call _GUICtrlMenu_GetSystemMenu() for the window in question, then called _GUICtrlMenu_AddMenuItem() to add a new menu item named "Pinned". This is working perfectly, but of course that's far from sufficient. Because obviously I need to establish some kind of event handler so that when the user selects that item, I can then toggle or alter the state and style of that item to show whether it's pinned or not. I've tried simply adding an on-event handler when I created the menu item, but even with the proper "Opt" value for On Event mode, the handler is never invoked. I also tried BrewmanNH's UDF and then LarsJ's, but even though I get no errors, again the handlers are never invoked. Finally, before I post the code of my last try using -- probably erroneously -- LarsJ's GUIRegisterMsg20 UDF, may I please ask for each of your recommendations and advice as to what approach you would favor? It's clear I don't know the most apt solution. Thanks! When you examine my code snippets, please overlook the mistakes and false starts that still remain there until I'm in the final stages of cleanup. Note also that the code depends vitally on Maps, so it will only run properly on the latest Beta version of AutoIt. But I guess that's actually irrelevant, since the posted code won't pass syntax checking... #AutoIt3Wrapper_Res_Fileversion=1.3 #AutoIt3Wrapper_icon=iPulse.ico #AutoIt3Wrapper_UseX64=Y #AutoIt3Wrapper_Run_After=copy "%out%" AutoWinSwitch.exe #include <WinAPIGdi.au3> #include <APIGdiConstants.au3> #include <GUIConstants.au3> #include <Misc.au3> #include <MsgBoxConstants.au3> #include <Process.au3> #include <String.au3> #include <StringConstants.au3> #include <Timers.au3> #include <WinAPIProc.au3> #include <GUIConstantsEx.au3> #include <GuiMenu.au3> ;~ #include <TrayConstants.au3> #include "LocalIncludes\GetMonitorTables_v1.1.au3" #include "LocalIncludes\_GetHwndFromPID.au3" #include "LocalIncludes\GUIRegisterMsg20.au3" AutoItSetOption("MustDeclareVars", 1) ; Variables must be declared before use AutoItSetOption("GUIOnEventMode", 1) ; We will temporarily disable this later for StateChange GUI AutoItSetOption("WinTitleMatchMode", 1) ; 1 = Matches partial titles from the start AutoItSetOption("MouseCoordMode", 0) ; 0 = Coords are relative to window (not screen) AutoItSetOption("GUICloseOnESC", 1 ) ; Close if user presses ESC AutoItSetOption("TrayOnEventMode", 0) ; We will enable this later ; ; Const $C_ThisAppName = "AutoWinSwitch" Const $C_VersionStr = "v1.3 Beta" Global Const $C_Title = $C_ThisAppName & " " & $C_VersionStr ; ;- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ; Const $C_AutoSwitchRegRootKey = "HKCU\Environment" Const $C_AutoSwitchRegValName = "AUTOWINSWITCHSTATE" Const $C_PathToTestApp = "B:\AutoIt Scripts\!ISN My Folder\My Projects\NFS Mounter\NFS_Mounter.exe" Const $C_StateDisabled=1, $C_StateBlockPrimary=2, $C_StateBlockSecondary=3, $C_StateUnset=4, $C_NumStateStrs=8 Const $C_ValidStateStrAra[$C_NumStateStrs] = [ "DIS", "TOP", "TOS", "DISABL", "BLOCKN", "BLOCKS", "BLOCKP", "NOTSET" ] Const $C_MoveTblNumCols=8 Global Enum $C_MoveTblHdlIx, $C_MoveTblMonIxIx, $C_MoveTblTitleIx, $C_MoveTblClassIx, $C_MoveTblProcIx, _ $C_MoveTblTypeIx, $C_MoveTblWinLocIx, $C_MoveTblDimsIx Const $C_NumDimCols=6 Global Enum $C_DimsWidthIx, $C_DimsHeightIx, $C_DimsLeftIx, $C_DimsTopIx, $C_DimsRightIx, $C_DimsBottomIx Const $C_CalcAbsLeft=1, $C_CalcAbsRight=2, $C_CalcAbsTop=3, $C_CalcAbsBot=4 Const $C_WinTypeMain=1, $C_WinTypePopup=2 Const $C_OnOpenMon = 1, $C_OnBlockedMon = 2, $C_SpansMon = 3 Const $C_TitlesToIgnoreAraCount = 7 Const $C_TitlesToIgnoreAra[$C_TitlesToIgnoreAraCount] = [ "Microsoft Text Input", _ "Program Manager", _ "*AutoIt", _ "Settings", _ "WorkerW", _ "*Debugger", _ "*DBUG" ] ;- - - - - - Global $G_GenMonTbl[$Gc_GMTblNumCols], $G_MMonitorTbl[1][$Gc_MMTblNumCols] Global $G_CurWinMap[], $G_PrevWinMap[], $G_PinnedMap[], $L_EmptyMap[] Global $G_MoveTimerAra[1][2], $G_MoveTimerAraIdx=-1, $G_AWS_HidWinHdl = -1 Global $G_MutexHdl, $G_WeOwnMutex, $G_Gid_PriRadioBtn, $G_Gid_SecRadioBtn, $G_Gid_DisabledRadioBtn Global $G_MonIxToShowGUI = 0 Global $G_SwitchStateStr, $G_SwitchStateCode, $G_SwitchStateChanged = False Global $G_NumValidMons=0, $G_TestAppPID, $G_TestAppWinHdl, $G_TestAppTitle="NFS_Mounter", $G_TestAppPosAra[2] ;~ $WM_CLOSE = 0x0010 ;~ $WM_MENUCOMMAND = 0x0126 ;~ $WM_MENUSELECT = 0x011F ;~ $WM_MOVE = 0x0003 ;~ $WM_MOVING = 0x0216 Global Enum $C_UseExtWinHdl, $C_UseExtCtrlHdl Global $G_SysWinMsgCodesRegAraCount = 5 Global $G_SysWinMsgCodesRegAra[$G_SysWinMsgCodesRegAraCount][3] = [ _ [ $C_UseExtWinHdl, $WM_CLOSE, __ExtCloseCmdHandler ], _ [ $C_UseExtWinHdl, $WM_MOVE, __ExtMoveWinHandler ], _ [ $C_UseExtWinHdl, $WM_MOVING, __ExtMovIngWinHandler ], _ [ $C_UseExtCtrlHdl, $WM_MENUCOMMAND, __ExtMenuCmdHandler ], _ [ $C_UseExtCtrlHdl, $WM_MENUSELECT, __ExtMenuSelectHandler ] ] ; ; - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - ; Local $L_WorkDir = "B:\ISN AutoIt Studio\Projects\AutoWinSwitch\AutoWinSwitch Release 1.3 Beta" $L_RptPath = _UniqueOutFilePath( "WinReport", "txt", $L_WorkDir, 99 ) If @error <> 0 Then MsgBox($MB_OK, $C_Title, "Error: Unable to generate unique output filepath -- Exiting...")

Quick description: I'm building an application for a friend who wants to quit the use of Picasa but is reluctant because of the customised order of his pictures. The only way I know how to retain the custom order is to export all folders (and/or albums) managed by Picasa. I suppose the quick question is whether the way to trap messages for a window and/or control of your own making (GUI) is fundamentally different from trapping it for windows in a third party GUI. If that makes sense. My wizard style application has grown steadily but mainly slowly I found out that almost none of the parts of Picasa are recognisable Windows controls. (according to Au3Info and several other detection tools I've tried) So far, I've managed to work around that by reading and writing values to the registry w/ regard to export size, export location and quality. However. the final step appears to be the most difficult for me. What I tried to do is for the user to indicate two folders by double clicking on them. (Those two folders represent the range of folders that have to be exported). On this forum I found a contribution by Rasim to subclass a Window and replace the Windows procedure by a new one; see https://www.autoitscript.com/forum/topic/76841-detect-double-click-on-edit-box/ Here is his code to detect a double click in an edit control: $hGUI = GUICreate("Test GUI", 300, 200) $edit = GUICtrlCreateEdit("", 10, 10, 280, 180) $wProcHandle = DllCallbackRegister("_WindowProc", "ptr", "hwnd;uint;wparam;lparam") $wProcOld = _WinAPI_SetWindowLong(GUICtrlGetHandle($edit), $GWL_WNDPROC, DllCallbackGetPtr($wProcHandle)) GUISetState() Do Until GUIGetMsg() = $GUI_EVENT_CLOSE GUIDelete($hGui) DllCallbackFree($wProcHandle) Func _WindowProc($hWnd, $Msg, $wParam, $lParam) Switch $hWnd Case GUICtrlGetHandle($edit) Switch $Msg Case $WM_LBUTTONDBLCLK ConsoleWrite("-> Left mouse double click" & @LF) Return 0 EndSwitch EndSwitch Local $aRet = DllCall("user32.dll", "int", "CallWindowProc", "ptr", $wProcOld, _ "hwnd", $hWnd, "uint", $Msg, "wparam", $wParam, "lparam", $lParam) Return $aRet[0] EndFunc The(/a) fundamental difference between this code and my program is that I try to do the same with Picasa and that that is not a GUI created in AutoIt. So instead of GUICtrlGetHandle($edit), I call the above function with the Picasa window handle. However, it doesn't work. Neither does Notepad if I pass its handle. I'm sure I express myself rather clumsily, but is it imperative to create and address your own GUI if you want to detect a double click in a third party program? Why wouldn't the above code work when automating a non AutoIt GUI? Cheers, Sando PS (Edit): I'm sure there are smarter ways to achieve what I want in Picasa, but I'm also really interested in AutoIts working. I was a Delphi developer in the past, and although i see quite a few similarities, especially between Koda and the IDE, I've also come to realise how much we Delphi developers have been shielded from the intricacies of Windows and its frameworks. I find AutoIt fascinating, and incredibly useful.

Good morning everyone I'm trying to build, and, first of all, understand, how a Virtual ListView works. By now, I've already downloaded all the samples from Virtual List View samples provided by @LarsJ, but I still don't understand few things. What I understood by now, is that the Virtual ListView doesn't need to be filled by object like Items, because it use directly the source to display the data. I've already understood that the $LVN_ODCACHEHINT Notification Code does provide the range of the items to be displayed, but I don't understand how to fill $iFrom and $iTo which are in the $NMLVCACHEHINT, or who fill them. And, "finally", I understood that the $LVN_GETDISPINFO is used to fill the ListView with "items". Can someone please explain to me how do these Virtual ListView controls work? Thanks in advance. Best Regards.
