I am trying to code to capture the packet loss on computers, but the only way I’ve been able to do so was to run the NetStat.exe and the TraceRt.exe processes and capture them to a listbox (using the code below): 

Private Sub myProcess()     Dim p As System.Diagnostics.Process     Dim theFile, sTemp, sLineOut, mySent, myRetrans As String     Dim intSentStart As Double     Dim isEnabled As Boolean      p = New System.Diagnostics.Process     theFile = t.Name      If File.Exists('c:\windows\system32\' & theFile) Then         theFile = 'c:\windows\system32\' & theFile     Else         MessageBox.Show('Unable to find the ' & theFile & ' file on your computer.', 'File Find Error!', MessageBoxButtons.OK, MessageBoxIcon.Error)     End If      Select Case t.Name         Case 'TraceRt.exe'             p.StartInfo.Arguments = '-h 30 www.stackoverflow.com'          Case 'NetStat.exe'             p.StartInfo.Arguments = '-s -p tcp'     End Select      Try         p.StartInfo.FileName = theFile         p.StartInfo.CreateNoWindow = True         p.StartInfo.UseShellExecute = False         p.StartInfo.RedirectStandardOutput = True         p.Start()         p.PriorityClass = System.Diagnostics.ProcessPriorityClass.Normal          sLineOut = ''          Do While Not p.HasExited             sTemp = p.StandardOutput.ReadLine()             If sTemp <> '' Then                 sLineOut = sLineOut & sTemp & vbNewLine                 'Send to listbox                 setTrace(sTemp)             End If         Loop         If sLineOut = '' Then             'Clear Listbox             clearTrace()             myProcess()             Exit Sub         End If         If t.Name = 'NetStat.exe' Then             Try                 If lboxTrace.Items.Count < 9 Then                     'Clear Listbox                     clearTrace()                     myProcess()                     Exit Sub                 End If                 mySent = ''                 mySent = lboxTrace.Items.Item(8) '('Segments Sent')                 mySent = Trim(mySent.Replace('Segments Sent', ''))                 mySent = Trim(mySent.Replace('=', ''))                  myRetrans = ''                 myRetrans = lboxTrace.Items.Item(9)                 myRetrans = Trim(myRetrans.Replace('Segments Retransmitted', ''))                 myRetrans = Trim(myRetrans.Replace('=', ''))                  intSentStart = Math.Round((myRetrans / mySent) * 100, 2)                  'setTrace sends data to the listbox                 If intSentStart < 2 Then                     setTrace('Your Current Packet Loss is: ' & intSentStart & '%.')                     setTrace('Your packet loss is within acceptable ranges.')                 Else                     setTrace('Your Current Packet Loss is: ' & intSentStart & '%.')                     setTrace('Your packet loss is below acceptable ranges!')                     setTrace('Please contact your Internet Provider about your Internet Connection.')                 End If              Catch ex As Exception                 'Clear Listbox                 clearTrace()                 myProcess()                 Exit Sub             End Try         End If     Catch ex As Exception         MessageBox.Show(ex.Message)     End Try  End Sub

Does anyone have a better idea to get this information? I’d rather use managed code instead of hacking through it this way.

Thanks in Advance! -JFV

  1. Not sure if this is what you’re looking for, but have you taken a look at the Ping class?

    Edit: Actually for TraceRoute, take a look at the answers here: TraceRoute and Ping in C#.

    For Netstat, take a look at http://towardsnext.wordpress.com/2009/02/09/netstat-in-c/.
