    {
        try
        {
            string exepath;
            string AppPath = Request.PhysicalApplicationPath.Replace("http:\\", "");
            ////Get the application path
            //exepath = Server.MapPath("Up2Wav.exe");
            exepath = Server.MapPath("tmp/Up2Wav.exe");
            string strCmd = exepath + " " + command;
            StreamWriter _testData = new StreamWriter(Server.MapPath("data.txt"), true);
            _testData.WriteLine(strCmd);
 

            System.Diagnostics.ProcessStartInfo procStartInfo =
                new System.Diagnostics.ProcessStartInfo("cmd", "/c " + strCmd);
            // The following commands are needed to redirect the standard output.
            // This means that it will be redirected to the Process.StandardOutput StreamReader.
            procStartInfo.RedirectStandardOutput = true;
            procStartInfo.UseShellExecute = false;
            // Do not create the black window.
            procStartInfo.CreateNoWindow = true;
            // Now we create a process, assign its ProcessStartInfo and start it
            System.Diagnostics.Process proc = new System.Diagnostics.Process();
            proc.StartInfo = procStartInfo;
            proc.Start();
            // Get the output into a string
            string result = proc.StandardOutput.ReadToEnd();
            // Display the command output.
            Console.WriteLine(result);
            _testData.WriteLine(result);
            _testData.Close();
            _testData.Dispose();
       
        }
        catch (Exception objException)
        {
            // Log the exception
        }
    }
