  //Set process properties
  oInfo.UseShellExecute = false;
  oInfo.CreateNoWindow = true;
  oInfo.RedirectStandardOutput = false;
  oInfo.RedirectStandardError = true;
  oInfo.RedirectStandardInput = true;

  process.StartInfo = oInfo;

  process.EnableRaisingEvents = true;
  process.ErrorDataReceived += new DataReceivedEventHandler(proc_ErrorDataReceived);
  process.Exited += new EventHandler(proc_Exited);

  process.Start();
  // this.pid = proc.Id;          
  process.BeginErrorReadLine();
}

public void stopProcess()
{
  process.StandardInput.WriteLine("q");
}
