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...")

Hey Guys, this is somewhat related to another post in here but my specific question was "answered" and so I thought I would make a new post that is referencing the same code, with slightly different issues. Problem 1 Setup: I am using a label docked to the main GUI to set the size of a child GUI. Issue: When I slowly drag the borders, I can see my green label kind of peeking out from behind the GUI, not a huge problem I guess. If I drag the border very quicky I can get the offset to be really big (200-300 pixels) ** Edit - I just realized that the child of the child GUI actually does not display this same "lag" or difference in sizing. hmmmm Problem 2 *discaimer! - Melba if you see this, I know you have Aero disabled so I understand if you don't want anything to do with this one! haha Setup: Using windows message WM_WINDOWPOSCHANGING. This should give me a message "While" the window is changing. There is a WM_WINDOWPOSCHANGED, which should fire after the change happens. Issue: Upon a normal maximize/restore methods (double clicking title bar, or using the buttons) the window behaves. Upon an Aero Snap maximize/restore the update only happens AFTER I let go of my left click. So while dragging the window down from its maximized state the child GUI's remain maximized until I let go of the left click mouse button and it resizes. I really want this to resize the second it unsnaps from the maximized state. **Edit - This is due to the way I am handling the flags parameter of the WINDOWPOS Struct. I'm masking only using 1 of the members and it only sees that once the LMB is released. So I am basically misusing the message because im not very familiar with it I have experimented with bitOR(member1, member2, member3) because im thinking SWP_FRAMECHANGED is not the only member I should be masking against "flags" (although it works somewhat) Here is my code. #include <GuiConstantsEx.au3> #include <WindowsConstants.au3> #include <WinAPI.au3> $iGuiWidth = 660 $iGUIHeight = 320 $DividerOffset = 244 Global $aGUIPos[6] Global $hgui, $hgui1, $hguiInner1, $cLabel_1, $cLabel_2, $cLabel_3, $iOFfset_X1, $iOFfset_Y1 Global $bSysMsg = False GUI() GUIRegisterMsg($WM_SIZE, "_WM_SIZE") GUIRegisterMsg($WM_WINDOWPOSCHANGING, "_WM_WINDOWPOSCHANGING") Func GUI() $hgui = GUICreate("test", $iGuiWidth, $iGUIHeight, -1, -1, BitOR($WS_OVERLAPPEDWINDOW, $WS_POPUP)) GUISetBkColor(0x666666) $cLabel_1 = GUICtrlCreateLabel("I am the label", 4, 65, $iGuiWidth - 7, 250) GUICtrlSetBkColor(-1, 0x00FF00) GUICtrlSetResizing(-1, BitOR($GUI_DOCKLEFT, $GUI_DOCKTOP, $GUI_DOCKBOTTOM, $GUI_DOCKWIDTH, $GUI_DOCKRIGHT)) GUICtrlSetState(-1, $GUI_DISABLE) GUISetState() $hgui1 = GUICreate("", $iGuiWidth - 7, $iGUIHeight - 70, -1, 60, $WS_POPUP, $WS_EX_MDICHILD, $hgui) GUISetBkColor(0x888888) GUISetState() $Divider = GUICtrlCreateLabel('', $DividerOffset, 0, 5, 250) GUICtrlSetBkColor(-1, 0xFF0000) GUICtrlSetResizing(-1, BitOR($GUI_DOCKWIDTH, $GUI_DOCKLEFT, $GUI_DOCKTOP, $GUI_DOCKBOTTOM)) GUICtrlSetCursor(-1, 13) GUISetState() $cLabel_2 = GUICtrlCreateLabel("I am the label", 249, 25, 403, 225) GUICtrlSetBkColor(-1, 0x0000FF) GUICtrlSetResizing(-1, BitOR($GUI_DOCKLEFT, $GUI_DOCKTOP, $GUI_DOCKBOTTOM, $GUI_DOCKWIDTH, $GUI_DOCKRIGHT)) GUICtrlSetState(-1, $GUI_DISABLE) GUISetState() $hGuiInner1 = GUICreate("", 403, 225, 252,28, $WS_POPUP, $WS_EX_MDICHILD, $hgui1) GUISetBkColor(0x555555) GUISetState() _GetGuiPos($hgui,0,1) _GetGuiPos($hgui1,2,3) ;~ _GetGuiPos(hgui2,3,4) For $i = 0 to 5 ConsoleWrite("$aguipos[" & $i & "]:=" & $aguipos[$i] & @LF) Next EndFunc ;==>GUI While 1 $msg = GUIGetMsg() Switch $msg Case $GUI_EVENT_CLOSE Quit() EndSwitch If $bSysMsg Then $bSysMsg = False _Resize_GUIs() EndIf WEnd Func Quit() Exit EndFunc ;==>Quit Func _Resize_GUIs() ;GUI1 $aWin1 = WinGetPos($hgui) $aRet1 = ControlGetPos($hgui, "", $cLabel_1) WinMove($hgui1, "", $aWin1[0] + $aGUIPos[0] + $aRet1[0], $aWin1[1] + $aGUIPos[1] + $aRet1[1], $aRet1[2], $aRet1[3]) $aWin2 = WinGetPos($hgui1) $aRet2 = ControlGetPos($hgui1, "", $cLabel_2) WinMove($hguiInner1, "", $aWin2[0] + $aGUIPos[2] + $aRet2[0], $aWin2[1] + $aGUIPos[3] + $aRet2[1], $aRet2[2], $aRet2[3]) ;~ $aWin3 = WinGetPos($hgui) ;~ $aRet3 = ControlGetPos($hgui, "", $cLabel_3) ;~ WinMove($hgui1, "", $aWin3[0] + $aGUIPos[4] + $aRet3[0], $aWin3[1] + $aGUIPos[5] + $aRet3[1], $aRet3[2], $aRet3[3]) EndFunc ;==>_Resize_GUIs func _WM_WINDOWPOSCHANGING($hWnd, $msg, $wParam, $lParam) Local $winpos_Struct = DllStructCreate("hwnd hwnd;hwnd hwndInsertAfter;int x;int y;int cx;int cy;uint flags", $lParam) $MaximizeOrRestore = bitand(DllStructGetData($winpos_Struct, "flags"), $SWP_FRAMECHANGED) if $MaximizeOrRestore > 0 then $bSysMsg = True endif EndFunc Func _WM_SIZE($hWnd, $msg, $wParam, $lParam) _Resize_GUIs() Return $GUI_RUNDEFMSG EndFunc ;==>_WM_SIZE Func _Exit($s_Msg) MsgBox(0, "Error", $s_Msg) Exit EndFunc Func _GetGuiPos($hTargGUI,$iArrayEle1,$iArrayEle2) $aWin = WinGetPos($hTargGUI) Local $tPoint = DllStructCreate("int X;int Y") DllStructSetData($tPoint, "X", 0) DllStructSetData($tPoint, "Y", 0) _WinAPI_ClientToScreen($hTargGUI, $tPoint) $aGUIPos[$iArrayEle1] = DllStructGetData($tPoint, "X") - $aWin[0] $aGUIPos[$iArrayEle2] = DllStructGetData($tPoint, "Y") - $aWin[1] EndFunc

It's been requested in the past to have multithreading to which the response was "It would take too much redesigning of Autoit" but what about Async? Multithreading and Async are two different things. This way we could put tasks in the background without having to fork processes. Right? Also better event handling would be nice rather than throwing everything in a while loop we could have some functionality like javascript which seems to be far more responsive and reliable as the more you add to your while loop the less change there is of your "event" getting caught for some reason (At least in my experience).

Hi folks, I've been happily abusing this forum resources (and many others as well) for over three years now to get stuff done in AutoIT3. I'm currently stuck at a point where i need to fake some sort of multithreading. I know AutoIT3 does not and will not support it, but if there only was a good way to tap into the full event trapping cycle of the AU3 engine, i could at least add in some of the routines that need a checkup. I figured so far that using the GuiOnEventMode and TrayOnEventMode should allow me to give me this opportunity, but unfortunately, it doesn't. I have extended the existing Au3 examples for both options with a counter to show what i mean: #include <GUIConstantsEx.au3> #include <Constants.au3> #NoTrayIcon Global $x = 1 Example() Func Example() Opt("GUICoordMode", 2) Opt("GUIResizeMode", 1) Opt("GUIOnEventMode", 1) Opt("TrayOnEventMode", 1) Opt("TrayMenuMode", 1) ; Default tray menu items (Script Paused/Exit) will not be shown.

EndSelect EndFunc ;==>SpecialEvent Func ExitEvent() Exit EndFunc ;==>ExitEvent The counter keeps updating the console output, until you hover above a Tray context menu or you click and hold down any of the scrollbars. The counter that i am running in the background here is in my real life a network process that needs to clear a message buffer from time to time. I have two applications in Autoit3 running, one server that is doing all the network activity and no GUI related stuff at all and i attach a client to it that has to exchange messages with the server to at least be able to command it up to some level. However whenever that message buffer of this client stalls, the server that is broadcasting the ACK messages will also stall eventually because his buffers do not get cleared. I have considered using an Sqlite database in WAL mode to exchange messages between the two apps and even if that can work mighty fast, it looks clumsy, but it ensures me that my client app will not crash on partial messages or miss out on messages. But if anyone can guide me to a trick where i could at least have all functions called in a processing loop without the AutoIT engine being able to stall that process, in other words:how can i keep that counter "running" at all cost? Thanks in advance!
