Get HANDLES of process

Recommended Posts

Hello!

Is it possible to get handles of a single running process?

Thanks

This is an cmd example:

wmic process get handlecount,description

Description HandleCount

System Idle Process 0

System 2085

winlogon.exe 618

services.exe 375

lsass.exe 582

svchost.exe 100

ProcessGetList()

The array returned is two-dimensional and is made up as follows:

$array[0][0] = Number of processes

$array[1][0] = 1st Process name

$array[1][1] = 1st Process ID (PID)

$array[2][0] = 2nd Process name

$array[2][1] = 2nd Process ID (PID)

...

$array[n][0] = nth Process name

$array[n][1] = nth Process ID (PID)

The list can be empty if $array[0][0] = 0. No @error set in this case.

So for example:

$arrProc = ProcessList()
MsgBox(0, "", $arrProc[3][1]

Will return the third processes PID.

Sorry!

I need "handlecount", not procesid

This is an example:

wmic process get handlecount,description

Is is possible with AutoIT3?

Ahh I am sorry about that. How about this?

#include <Constants.au3>

ConsoleWrite(_HandleCount() & @CRLF)

Func _HandleCount()
    Local $sStatus = Run(@ComSpec & " /c wmic process get handlecount,description", @SystemDir, @SW_HIDE, 8)
    Local $sBuf, $sOutput
    While 1
        $sBuf &= StdoutRead($sStatus)
        If @error Then ExitLoop
    Wend
    ; Now tidy the output and get the information we want
    $sBuf = StringStripWs($sBuf, 4)
    $sBuf = StringRegExpReplace($sBuf, "[a-zA-Z_.]", "")
    $sBuf = StringStripWs($sBuf, 4)
    $aBuf = StringSplit($sBuf, " ")
    For $i = 2 To $aBuf[0] - 2 ; From the 2nd array value to the second from last to remove annoying whitespace
        $sOutput &= $aBuf[$i] & @CR
    Next
    Return $sOutput
EndFunc   ;==>_ParentDir

It returns a list (separated by @CR) with all of the handles.

Actually, that code above is useless. It's returning nothing of any use. Let's see if I can make it work like ProcessList() ;)

Very very good!

Thanks again!

Is that what you're after?

Also, if you only want to get the handlecount for one process, the WMIC query language does have a WHERE clause, so for example, you can get the HandleCount for explorer.exe like so:

ConsoleWrite(_ProcessGetHandle("explorer.exe") & @CRLF)

Func _ProcessGetHandle($ioProcName)
    Local $sStatus = Run(@ComSpec & " /c WMIC PROCESS WHERE Name='" & $ioProcName & "' GET handlecount", @SystemDir, @SW_HIDE, 8)
    Local $sBuf
    While 1
        $sBuf &= StdoutRead($sStatus)
        If @Error then ExitLoop ; We have lift off, let's go!
    WEnd
    $sBuf = StringStripCR($sBuf)
    $sBuf = StringRegExpReplace($sBuf, "HandleCount", "")
    $sBuf = StringStripWS($sBuf, 3)
    Return $sBuf
EndFunc

My regular expression is lousy, but it removes the text we don't want ;)

I also strip out the carriage returns and any whitespace which is leading or trailing.

Remember: Some processes (like cmd.exe for example) return more than one HandleCount :evil:

Yes!

This is perfect for me!

I need to check, kill and restart a single process with big handles leak

Awesome! Here is a little script which uses the ProcessList() I showed you earlier. We loop through the processes and get the process name and its handle. I've also added some error checking to the _ProcessGetHandle function ;)

$arProc = ProcessList()

For $i = 1 to $arProc[0][0]
    $arStat = ProcessGetStats($arProc[$i][1], 0)
    If IsArray($arStat) Then
        ConsoleWrite("Process Name: " & $arProc[$i][0] & " - Handle: " & StringReplace(_ProcessGetHandle($arProc[$i][0]), @LF, " - ") & @CRLF)
    EndIf
Next

Func _ProcessGetHandle($ioProcName)
    If $ioProcName Then
        Local $sStatus = Run(@ComSpec & " /c WMIC PROCESS WHERE Name='" & $ioProcName & "' GET handlecount", @SystemDir, @SW_HIDE, 8)
        Local $sBuf
        While 1
            $sBuf &= StdoutRead($sStatus)
            If @Error then ExitLoop ; We have lift off, let's move on!
        WEnd
        $sBuf = StringStripCR($sBuf)
        $sBuf = StringRegExpReplace($sBuf, "HandleCount", "")
        $sBuf = StringStripWS($sBuf, 3)
        If StringInStr($sBuf, "No Instance(s) Available.") Then
            ; Just incase we enter a bad process name
            SetError(2)
            Return 0
        EndIf
        Return $sBuf
    Else
        SetError(1)
        Return 0
    EndIf
EndFunc
