An oldie but goodie, I was cleaning house and found this old snippet I made back in Apr 2013. It still has some utility, so I figured I'd share it. It runs netstat and populates the output into an array. Very Pretty simple. #include <Constants.au3> #include <Process.au3> #include <Array.au3> Local $aNetStatData = _NetStat_GetData() Local $sHeaders = _ArrayToString($aNetStatData,"|",0,0) _ArrayDelete($aNetStatData, 0) _ArrayDisplay($aNetStatData,"NetStat", "", 32, Default, $sHeaders) Func _NetStat_GetData($bAddProcessName = True) Local $aNetStatData = _NetStat_ProcessOutput(_NetStat_GetOutput()) If $bAddProcessName Then _NetStat_AddProcessName($aNetStatData) Return $aNetStatData EndFunc Func _NetStat_GetOutput() ;Run netstat CMD and get StdOut Local $sNetStatOutput = _RunCMD("netstat.exe -a -o -f") Return $sNetStatOutput EndFunc Func _NetStat_ProcessOutput($sNetStatOutput) ;Convert netstat StdOut to Array Local $arr = StringSplit(StringStripWS($sNetStatOutput,4),@CR) Local $aRecord Dim $aNetStatData[1][5]=[["Protocol","Local Address","Foreign Address","State","PID"]] ReDim $aNetStatData[$arr[0]-3][5] For $iX = 1 To UBound($aNetStatData)-1 $aRecord = StringSplit($arr[$iX+3]," ") If $aRecord[1]="TCP" Then For $iY = 0 to $aRecord[0]-1 $aNetStatData[$iX][$iY] = $aRecord[$iY+1] Next ElseIf $aRecord[1]="UDP" Then For $iY = 0 to $aRecord[0]-2 $aNetStatData[$iX][$iY] = $aRecord[$iY+1] Next $aNetStatData[$iX][4] = $aRecord[4] EndIf Next Return $aNetStatData EndFunc Func _NetStat_AddProcessName(ByRef $aNetStatData) ;Add processname to NetStat Array ;Create NetStat PID / Process Name Array Local $aPIDs = _ArrayUnique($aNetStatData,4,0,0,0) _ArrayColInsert($aPIDs,1) $aPIDs[0][1] = "Process Name" For $iX = 1 To UBound($aPIDs)-1 $aPIDs[$iX][1] = _ProcessGetName($aPIDs[$iX][0]) Next ;Add Process Names to NetStat Array _ArrayColInsert($aNetStatData,5) $aNetStatData[0][5] = "Process Name" For $iX = 1 to UBound($aNetStatData)-1 Local $sProcessName = $aPIDs[_ArraySearch($aPIDs, $aNetStatData[$iX][4])][1] If $sProcessName Then $aNetStatData[$iX][5] = $sProcessName Next EndFunc Func _RunCMD($sCMD) ;Run CMD and Return StdOut Local $iPID = Run(@ComSpec & " /c " & $sCMD, @SystemDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD) Local $sStdOut While 1 $sStdOut &= StdoutRead($iPID) If @error Then ExitLoop WEnd Return $sStdOut EndFunc

I'm using my script to monitor established connections with the network. I'm using combination of RUN and NETSTAT command, however, constantly calling netstat from CMD doesn't feel elegant enough, and it's causing my script to perform really slow. Is there more elegant solution, an alternative for calling netstat?
