Read fileversion of running process

Question

I'm collecting information about running processes (like CPU- and RAM usage). Now I want to get the version number of a process via its PID or process name. How can I do this?

Answer 1

The version number suppose you determine the exe and its path behind the PID (in order to call FileGetVersion() with it).

This thread discuss how to do that, and propose the following script:

#include <Array.au3>

$aProcListEx = _ProcessListEx()
$yourExe = "jqs.exe"

If @error Then
    MsgBox(48, "_ProcessListEx - Error", StringFormat("There was an error to get ProcessList (@error = %i)", @error))
Else
 For $i = 1 to $aProcListEx[0][0]
 If $aProcListEx[$i][0] = $yourExe Then
     $Version = FileGetVersion($aProcListEx[$i][4],"FileVersion")
     MsgBox(0,"","Path to '" & $YourExe & "' is '" & $aProcListEx[$i][5] & "'" & @CRLF & "File Version is: " & $Version)
 EndIf
 Next
EndIf

; Function Name:    _ProcessListEx()
;
; Function Description: Gets Process List with extended info, plus can retrieve only a processes with specific resources strings.
;
; Parameter(s):     $sResourceName [Optional] - Resource name of the process filename, i.e. "CompiledScript".
;   $sInResString [Optional] - String to check in the resource name.
;   $iWholeWord [Optional] - Defines if the $sInResString will be compared as whole string (default is 1).
;
; Requirement(s):   None.
;
; Return Value(s):  On Success - Return 2-dimentional array, where:
;   $aRet_List[0][0] = Total processes (array elements).
;   $aRet_List[N][0] = Process Name.
;   $aRet_List[N][6] = PID (Process ID).
;   $aRet_List[N][7] = Process File Path.
;   On Failure - Return '' (empty string) and set @error to:
;   1 - Unable to Open Kernel32.dll.
;   2 - Unable to Open Psapi.dll.
;   3 - No Processes Found.
