Getting a window handle from PID for more advanced programs

Recommended Posts

I know it was discussed before, but the Wiki supposedly has an official solution to "How can I get a window handle when all I have is a PID?". Alas, it doesn't seem to work for anything more complicated than Notepad.

It completely fails, for example, with IE & Firefox (even with "-new-window URL").

In addition, if you try to run multiple instances of the same program, than it fails with programs such as Chrome (i.e. it only works on the first instance).

I've tried the various alternative unofficial forum versions as well, to no avail.

The reason why it's so important is, for example, launching a browser with multiple resolutions.

Thanks!

I do this with '?do=embed' frameborder='0' data-embedContent>>in the function _UIA_StartSUT you can find some logic

$oSUT=_UIA_getObjectByFindAll($oDesktop, "processid:=" & $result2, $treescope_children)


 

func _UIA_StartSUT($SUT_VAR)
    local $fullName=_UIA_getVar( $SUT_VAR & ".Fullname")
    local $processName=_UIA_getVar($SUT_VAR & ".processname")
    local $app2Start=$fullName & " " & _UIA_getVar($SUT_VAR & ".Parameters")
    local $workingDir= _UIA_getVar($SUT_VAR & ".Workingdir")
    local $windowState=_UIA_getVar($SUT_VAR & ".Windowstate")
    local $result, $result2   ; Holds the process id's

;~  _UIA_Debug("SUT 1 Starting : " & $fullName & @CRLF)
    if fileexists($fullName) Then
;~      _UIA_Debug("SUT 2 Starting : " & $fullName & @CRLF)
;~      Only start new instance when not found
        $result2=processexists($processName)
        if $result2=0 Then
            _UIA_Debug("Starting : " & $app2Start & " from " & $workingDir)
            $result=run($app2Start,$workingDir, $windowState )
            $result2=ProcessWait($processName,60)
;~          sleep(500) ;~ Just to give the system some time to show everything
        EndIf

;~ Wait for the window to be there
        $oSUT=_UIA_getObjectByFindAll($oDesktop, "processid:=" & $result2, $treescope_children)
        if not isobj($oSUT) Then
            _UIA_Debug("No window found in SUT : " & $app2Start & " from " & $workingDir)
        Else
        ;~ Add it to the Runtime Type Information
            _UIA_setVar("RTI." & $SUT_VAR & ".PID", $result2)
            _UIA_setVar("RTI." & $SUT_VAR & ".HWND", hex(_UIA_getPropertyValue($oSUT, $UIA_NativeWindowHandlePropertyId)))
;~          _UIA_DumpThemAll($oSUT,$treescope_subtree)
        EndIf
    Else
        _UIA_Debug("No clue where to find the system under test (SUT) on your system, please start manually:" & @CRLF )
        _UIA_Debug($app2Start & @CRLF)
    EndIf
EndFunc

Unfortunately, the second option (which, BTW, was moved to require WinAPIProc.au3 nowadays) didn't do the job for me.

junkew's solution would require more research.

OK. Good luck.

Yo guise, this works (Tested just now, just posting this incase anyone else had the same problem

 
Func _GetHwndFromPID($PID)
    $hWnd = 0
    $stPID = DllStructCreate("int")
    Do
        $winlist2 = WinList()
        For $i = 1 To $winlist2[0][0]
            If $winlist2[$i][0] <> "" Then
                DllCall("user32.dll", "int", "GetWindowThreadProcessId", "hwnd", $winlist2[$i][1], "ptr", DllStructGetPtr($stPID))
                If DllStructGetData($stPID, 1) = $PID Then
                    $hWnd = $winlist2[$i][1]
                    ExitLoop
                EndIf
            EndIf
        Next
        Sleep(100)
    Until $hWnd <> 0
    Return $hWnd
EndFunc ;==>_GetHwndFromPID

      I hoping some of you young people can help an old man get off the nickel...  I have a small project I'd like to complete before I retire.  My problem is that on a terminal server environment I need to be able to detect the PID of a process by 'process name' AND 'process owner' so I can kill that specific process and not affect others who may be running the same process in another session.    I can seem to do one or the other but not both.  Can anyone please point me in the right direction?  Thanks very much in advance. -Glen

      I'm trying to kill a malware process, that I can't remove with my www.sophus.com/hom antivirus.

      The malware is known as coinminer,config and my Sophus only creates popups of blocking the malware.

      I know that the malware is constantly launching a svchost *32.exe processes, where the svchost.exe processes are from my Windows 7 operating system.
      I have with no luck tried to do this:
      Global $_bStatus = False
      While $_bStatus = False
                 Global $_iPid
                 Global $_sActiveTitleNew = "svchost *32.exe"
                 $_iPid = WinGetProcess($_sActiveTitleNew)
                 If $_iPid <> -1 Then $_bStatus = ProcessClose($_iPid)   
      Wend
      EXIT
       
      But the $_iPid doesn't ever show anything else than  -1, even if I can see the svchost *32.exe process in my TaskManager
       
      YES - I know I shouldn't EXIT after killing the first malware detection, but it is easier to explain the above for you, so I can get a solution.

      Hello all,
      I've written the code below which launches chrome in incognito mode and then proceeds to go to the autoit website.
      From my understanding, the Run() command is also supposed to output the PID number related to the application that got launched from the Run command.
      However when I run the below lines, it outputs a PID number that is different from the newly launched chrome browser's PID number, does anyone know why and possibly explain how I could retrieve the accurate PID number associated with the newly launched browser?
      Global $iPid = Run(@ComSpec & ' /c start chrome.exe https://www.autoitscript.com/forum/ -incognito' ,"", "") msgbox(0,"",$iPid) Thank you,
      Brian

      Is it posible to get Internet traffic from a PID, like download and upload speeds. I did some research but nothing useful. ty

Then (not included I tried making a separate function to write to a INI file. that was a lesson in frustration and defeat. It worked.. just the same as the code in the function now. as soon as you click the button and the runwait line starts the ini gets updated. The file can only be written to after runwait is running is closed. Also tried the ProcessWait, ProcessWaitClose,  ShellExecute, ShellExecuteWait
