Hi guys,

Sorry for my bad englsih i'm french :sweating: .

I've got a script that kill notepad.exe if the owner that has launched it is the user that has opened the windows session :

#NoTrayIcon
;#include <Array.au3>; Only for _ArrayDisplay()


While 1
    Sleep(10)
    TestProcess()
WEnd


Func TestProcess()
    $AllProcesses = ProcessList()
    For $i = 1 To $AllProcesses[0][0]
        If StringInStr($AllProcesses[$i][0], "notepad.exe") And StringInStr(_ProcessGetOwner($AllProcesses[$i][1], "."), @UserName) Then ProcessClose($AllProcesses[$i][0])
    Next
EndFunc   ;==>TestProcess

;===============================================================================
;
; Function Name:    _ProcessGetOwner()
; Description:      Get the owner of an open process
; Parameter(s):     $vProcess - PID of a process.
; $strComputer - Name of target computer
; Requirement(s):   AutoIt Beta v3.2.+
;                   cimwin32.dll (included with Windows)
; Return Value(s):  On Success - Returns owners username of process
;                     0 - Successful, returns username
;
; On Failure:       Returns friendly errormessage and sets @Error to:
;                     2 - Access denied
;                     3 - Insufficient privilege
;                     8 - Unknown failure
;                     21 - Path not found

; Author(s):        Andreas Fälldin
;===============================================================================

Func _ProcessGetOwner($vProcess, $strComputer)

    Local $i_PID = ProcessExists($vProcess)
    If Not $i_PID Then
        SetError(1)
        Return -1
    EndIf

    Local $wbemFlagReturnImmediately = 0x10
    Local $wbemFlagForwardOnly = 0x20
    Local $colItems = ""
    Local $strUser = ""

    $objWMIService = ObjGet("winmgmts:{impersonationLevel=impersonate}!\\" & $strComputer & "\root\CIMV2")
    $colItems = $objWMIService.ExecQuery("SELECT * FROM Win32_Process WHERE ProcessID = " & $i_PID, "WQL", _
            $wbemFlagReturnImmediately + $wbemFlagForwardOnly)

    If IsObj($colItems) Then
        For $objItem In $colItems
            $rc = $objItem.GetOwner($strUser)

            Switch $rc
                Case 0
                    SetError(0)
                    Return $strUser
                Case 2
                    SetError(2)
                    Return "ACCESS DENIED"
                Case 3
                    SetError(3)
                    Return "INSUFFICIENT PRIVILEGE"
                Case 8
                    SetError(8)
                    Return "UNKNOWN FAILURE"
                Case 9
                    SetError(9)
                    Return "PATH NOT FOUND"
                Case 21
                    SetError(21)
                    Return "INVALID PARAMETER"
                Case Else
                    SetError(1)
                    Return -1
            EndSwitch
        Next
    EndIf
EndFunc   ;==>_ProcessGetOwner

But if the user closes notepad.exe when we are in the function, the line "$rc = $objItem.GetOwner($strUser)" returns an error and my script stops. How can i do to go out of the function when it happens without exit from autoit because why script must continue to run ?

Hi guys,

First thanks for your help...

The error is :

The requested action with this object has failed.:

$rc = $objItem.GetOwner($strUser)

$rc = $objItem.GetOwner($strUser)^ ERROR

It's always happen when i close notepad.exe manually (with a click or file/quit). Try it : open and close notepad.exe a lot of times and you'll see.

I cannot, because as soon as it opens it closes.

That is the function of the code?

Same here, it just closes, opened notepad numerous times, it wont even allow me to click to close because it closes much faster than i ever could.

ok, now try to open notepad.exe a lot of time (via cmd and arrows, it's more easy) : you should have the error. Or modify the "sleep(10)" to sleep(3000).

I was able to reproduce after a while, but cannot like this.

Func TestProcess()
    $AllProcesses = ProcessList('notepad.exe')
    For $i = 1 To $AllProcesses[0][0]
        $ownwer = _ProcessGetOwner($AllProcesses[$i][1], ".")
        If StringInStr($AllProcesses[$i][0], "notepad.exe") And StringInStr($ownwer, @UserName) Then ProcessClose($AllProcesses[$i][0])
    Next
EndFunc   ;==>TestProcess

I think the problem arises when, between the time it takes to verify $colItems as object and loop through $objItem getting the user, the window has been closed and hence we can not get the user for a non existing item.

Only way I can see to handle this is using a com error handler <- help file will show you example.

Thx JohnOne for this script, i didn't know "com error handler", i thk it's very usefuul to debug !

I'm agree with you about the origin of the problem : i call object that has been destroyed...

I've just test your script and i get this :

ERROR NUMBER : 80020009

WinDescription :

Script Line: -1

What does it mean and what can i do ?

I think i must exit from the function "_ProcessGetOwner" or return nothing when i see this type of error, but how can i do that ?

like this ?

$rc = $objItem.GetOwner($strUser)

Switch $rc

Case 0

SetError(0)

Return $strUser

Case 2

SetError(2)

Return "ACCESS DENIED"

Case 3

SetError(3)

Return "INSUFFICIENT PRIVILEGE"

Case 8

SetError(8)

Return "UNKNOWN FAILURE"

Case 9

SetError(9)

Return "PATH NOT FOUND"

Case 21

SetError(21)

Return "INVALID PARAMETER"

Case 80020009

SetError(0)

Return ""

You don't need to do much, or anything really, just stop the scripts from crashing.
