Run / RunWait and Exit Codes

Just a small question for the learned masses if i may

I have a script that uses command line to access Winrar and MultiPar and ive run into this scenario

I currently use RunWait like this

$ProcessPID = RunWait(@ComSpec & ' /c ' & @TempDir & '\Sup\par2j.exe' & ' r ' & '"' & $aParFile[$i] & '"', "", @SW_HIDE)

and then i access $ProcessPID for all the exit codes of which there are many to provide error support for all the command programs i am using.

So i made all the script, then i realised that i couldn't cancel the process and further investigation it looks like i will have to completely rewrite to be able to halt the process

and use Run to be able to do it.

The downside is i lose all that error support built in to the programs as i cant access it from Run

and only give basic support like this

                ProcessWait($ProcessPID)
                $sOutput = ""
                While 1
                    $sOutput = StdoutRead($ProcessPID)
                    If StringInStr($sOutput, "Password", 2) > 0 Then ; Monitoring Window for specific text during test process
                        MsgBox(64, "Password Error", "Archive Is Passworded")
                        Exit
                    ElseIf StringInStr($sOutput, "No files extracted", 2) > 0 Then ; Monitoring Window for specific text during test process
                        MsgBox(64, "Archive Error", "Archive Extraction Failed")
                        Exit
                    EndIf
                WEnd

This is a shame because the support is already there and i cant access it.

So the question i would like to ask is..

Can Run be made to return the $PID and if you set a flag then it returns the exit codes from the programs?

There probably is a horrendously complicated answer but i would interested to hear why or why not.

Thanks for your time
