Call a exe file from server

[Nelson]

Hi there,

I´m trying call in my silverlight application some exe file to convert mp3 to ogg.

To do that, I create a process and call the .exe file like this:

 string caminhoPastaTemp = caminhoPathTemp;
                int timeout = 9000;

                if (!Directory.Exists(caminhoPastaTemp))
                    throw new Exception("Erro: caminho da pasta temporária incorrecto! [" + caminhoPastaTemp + "]");

                //parar processos que estejam a correr
                Process[] listaProcessos;
                listaProcessos = Process.GetProcessesByName("BeSweet");
                
                foreach (Process p in listaProcessos)
                {
                    p.WaitForExit();
                    if (!p.HasExited)
                    {
                        p.Kill();
                        p.Dispose();
                        p.Close();
                    }
                }

                //obter sessionid
                int sessionid = 0;
                Process[] procs = Process.GetProcesses();
                for (int i = 0; i < procs.Length; i++)
                {
                    if (procs[i].ProcessName.ToUpper().Equals("EXPLORER"))
                        sessionid = procs[i].SessionId;
                }


                //iniciar processo que executa beSweet para conversão
                Process proc = new Process();
                proc.StartInfo.WorkingDirectory = caminhoPastaTemp;
                proc.StartInfo.RedirectStandardOutput = true;
                
                
                string strArgumentos = Util.DevolvePathRaizAplicacao() +"\\ConverteGravacao\\BeSweet.exe -core ( -input " + nomeFicheiroEntrada + " -output " + nomeFicheiroSaida + " -logfilea log.log ) -ogg( -b 160 )";//+ " -logfilea \"%1_CONV_LOG.log\"
                //string strArgumentos = " -core ( -input " + nomeFicheiroEntrada + " -output " + nomeFicheiroSaida + " -logfilea log.log ) -ogg(  )";
                
                
                proc.StartInfo.Arguments = strArgumentos;
                proc.StartInfo.CreateNoWindow = false;
                proc.StartInfo.FileName = Util.DevolvePathRaizAplicacao() + "\\ConverteGravacao\\BeSweet.exe";
                //proc.StartInfo.FileName = "calc.exe";
                proc.StartInfo.RedirectStandardError = true;
                proc.StartInfo.RedirectStandardOutput = true;
                proc.StartInfo.UseShellExecute = false;



                proc.Start();

                proc.WaitForExit(timeout);
                

                //verificar se processo terminou
                listaProcessos = Process.GetProcessesByName("BeSweet");
                foreach (Process p in listaProcessos)
                {
                     p.WaitForExit(timeout);
                    if (!p.HasExited)
                    {
                        p.Kill();
                        p.Dispose();
                        p.Close();
                    }
                }
                proc.WaitForExit();
                proc.Dispose();

            }
            catch(Exception ex)
            {
                string erro = ex.Message;
            }

But the process finish unexpectedly and only convert 5 seconds of audio..always 5 seconds.

I tried increase timeout for huge values, but the problem is the same...

The folder have admin permissions, I execute this with admin permissions in VS2010, but the problem is the same..

Note that this code is running in server-side. Another thing, if I call the windows calculator for example, works good..

Can anyone tell me why happens this?

Thanks in advance.
