https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-terminateprocess Internally, (based on the documentation that you posted) this calls "TerminateProcess" in processthreadsapi.h Which states,

I think there will be an error when one of the processes is terminating and you try terminating it again as the function will try to terminate the process with the highest PID.That would stop the loop. The second script will simply continue till none exists. Jos

enough. *Click*

This UDF allows to set an events handler for Mouse device. The beginning... I searched for a way to disable the Mouse Primary click, and be able to call some function when the click event is received... Big thanks to amel27 for this one, i only organized the whole stuff to UDF style. Example: #include <GUIConstantsEx.au3> #include "MouseOnEvent.au3" HotKeySet("{ESC}", "_Quit") _Example_Intro() _Example_Limit_Window() Func _Example_Intro() MsgBox(64, "Attention!", "Let's set event function for mouse wheel *scrolling* up and down", 5) ;Set event function for mouse wheel *scrolling* up/down and primary button *down* action (call our function when the events recieved) _MouseSetOnEvent($MOUSE_WHEELSCROLLDOWN_EVENT, "_MouseWheel_Events") _MouseSetOnEvent($MOUSE_WHEELSCROLLUP_EVENT, "_MouseWheel_Events") _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT, "_MousePrimaryDown_Event") Sleep(3000) ;UnSet the events _MouseSetOnEvent($MOUSE_WHEELSCROLLDOWN_EVENT) _MouseSetOnEvent($MOUSE_WHEELSCROLLUP_EVENT) _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT) ToolTip("") MsgBox(64, "Attention!", "Now let's disable Secondary mouse button up action, and call our event function.", 5) _MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT, "_MouseSecondaryUp_Event", 0, 1) Sleep(5000) _MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT) ToolTip("") EndFunc Func _Example_Limit_Window() Local $hGUI = GUICreate("MouseOnEvent UDF Example - Restrict events on specific window") GUICtrlCreateLabel("Try to click on that specific GUI window", 40, 40, 300, 30) GUICtrlSetFont(-1, 12, 800) GUICtrlCreateLabel("Press <ESC> to exit", 10, 10) GUISetState() _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT, "_MousePrimaryDown_Event", $hGUI) ;A little(?) bugie when you mix different events :( ;_MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT, "_MouseSecondaryUp_Event", $hGUI) While 1 Switch GUIGetMsg() Case $GUI_EVENT_CLOSE ExitLoop Case $GUI_EVENT_PRIMARYDOWN MsgBox(0, "", "Should not be shown ;)") EndSwitch WEnd _MouseSetOnEvent($MOUSE_PRIMARYDOWN_EVENT) ;_MouseSetOnEvent($MOUSE_SECONDARYUP_EVENT) EndFunc Func _MouseWheel_Events($iEvent) Switch $iEvent Case $MOUSE_WHEELSCROLLDOWN_EVENT ToolTip("Wheel Mouse Button (scrolling) DOWN Blocked") Case $MOUSE_WHEELSCROLLUP_EVENT ToolTip("Wheel Mouse Button (scrolling) UP Blocked") EndSwitch Return $MOE_BLOCKDEFPROC ;Block EndFunc Func _MousePrimaryDown_Event() ToolTip("Primary Mouse Button Down Blocked") Return $MOE_BLOCKDEFPROC ;Block EndFunc Func _MouseSecondaryUp_Event() ToolTip("Secondary Mouse Button Up Blocked") EndFunc Func _Quit() Exit EndFunc Available Events Constants: ------------------------------------------ CHANGELOG: Download: Attached: MouseOnEvent_2.4.zip Old version: MouseOnEvent.zip - v2.3 MouseOnEvent_2.1.zip MouseOnEvent_2.0.zip MouseOnEvent_UDF_1.9.zip MouseSetOnEvent_UDF_1.8.zip MouseSetOnEvent_UDF_1.7.zip MouseSetOnEvent_UDF_1.6.zip MouseSetOnEvent_UDF_1.5.zip MouseSetOnEvent_UDF_1.4.zip MouseSetOnEvent_UDF_1.3.zip Previous downloads: 146 + 200 + 804 MouseOnEvent.zip MouseOnEvent.zip

This roundup of "virtual keyboards" (https://www.buttoncommander.com/en/input-devices/difference-between-hotkeyboard-devices-and-keyboard-devices/) inspired me to create this simple "LaunchPad" script. with this script you can easily create panels with buttons for starting programs, but not only, you can also associate macros, shortcuts, functions with the buttons ... In short, the $aTools 2D array contains the settings that determine the behavior of each "Button", namely 4 parameters for each row (for each button); [n][0] the tooltip of the button [n][1] path of an icon or a file containing icons [n][2] the number of the icon (if the previous parameter is a collection) [n][3] AutoIt command(s) to be executed directly on button click (or also the name of a function) (see the script for some examples of use) If you have ideas for new records for that array you are encouraged to post it here (thanks) You can easily change the buttons dimensions and the shape of the initial deck by changing the $iStep and $iNrPerLine variables in the script (deck is resizeable as well) Credits: This script makes use of some useful snippets kindly provided by @KaFu, @Danyfirex and @mikell (see the comments in the script for references) Tips (or ready made modifications) for improvements are as always welcome. have fun ; =============================================================================================================================== ; Title .........: LaunchPad ; Description ...: button deck to be used as an applications launcher (and not only) ; Author(s) .....: Chimp (Gianni Addiego) ; credits to @KaFu, @Danyfirex, @mikell (see comments for references) ; =============================================================================================================================== #include <WindowsConstants.au3> #include <GUIConstantsEx.au3> #include <WinAPI.au3> ; <WinAPISysWin.au3> #include <SendMessage.au3> #include <WinAPIFiles.au3> ;Turn off redirection for a 32-bit script on 64-bit system.

I don't see anything in the source about caching processes or checking 250ms. It seems to build the process list with each call. I did manage a few times to get an error 1 Extended 87 and not closing all notepad.exe processes with this script: for $x = 1 to 10 run("notepad.exe") Next Sleep(1000) While ProcessClose("notepad.exe") WEnd ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : WEnd =>Error code: ' & @error & @CRLF) ;### Debug Console So we receive a returncode 87 for an OpenProcess() call to PROCESS_TERMINATE an PID that doesn't exists anymore. So to me that means in between the time we did the ProcessList, checked for the first occurrence and doing the actual ProcessOpen() , this PID was gone. Sleep(1) doesn't really exists and believe 10 is the minimum. Agree, and the only thing I can think of is that the Helpfile doc was copied from ProcessWaitClose and forgotten to remove that line. Jos

The 250ms polling is common to all of the functions like Process*... I'm not 100% sure how it applies here. Maybe it means that it won't check the processes more than once every 1/4 of a second? This is actually really cool though, you can see by the error values how it works internally... first, they open the process handle (OpenProcess), they enable some disabled privileges (AdjustTokenPrivileges), before finally terminating the process (TerminateProcess).

Good explanation by @Jos, this is a classic race-condition problem. A proper solution would be to get a list of all processes and then using ProcessClose on each one of them, but using ProcessExists in a loop also does the trick, albeit in a less CPU efficient manner

Which makes a lot of sense ...right?

Thank you very much for the interesting story. "argumentum" is indeed a catchy identification mark.

Is there a way to make them Local? Local $List1 = GUICtrlCreateList("Double-Click Me", 16, 8, 321, 123) MyFunc(0, $idDummy, 0, $List1) ; <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< GUICtrlSetData($List1, "Or... Double-Click Me...") GUISetState(@SW_SHOW) GUIRegisterMsg($WM_COMMAND, "MyFunc") While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE GUIDelete($Form2) ExitLoop Case $idDummy MsgBox(0, "", GUICtrlRead($idDummy)) EndSwitch WEnd EndFunc Func MyFunc($hWnd, $iMsg, $wParam, $lParam) Local Static $idDummy, $List1 Local $hWndFrom, $iIDFrom, $iCode, $hWndEdit $hWndFrom = $lParam $iIDFrom = _WinAPI_LoWord($wParam) $iCode = _WinAPI_HiWord($wParam) If $iCode = $LBN_DBLCLK AND $iIDFrom = $List1 Then $sClicked = GUICtrlRead($List1) GUICtrlSendToDummy($idDummy, $sClicked) Return 0 EndIf If $hWnd = 0 And $wParam = 0 Then $idDummy = $iMsg $List1 = $lParam EndIf EndFunc

@water As argumentum writes, it was meant. Everybody is welcome to test, but I wanted to honor these two users, because they have tested before. Nevertheless thanks for the hint. I was also of this opinion, but did not know if I was right. Thank you very much for this important information. 👍
