TCP Client for Windows Mobile 6.1 PDA

Question

Hi,

I am developing a TCP client application for PDA powered by Windows Mobile 6.1, I am using VS 2008 with TCPClient class of System.Net.Sockets namespace to send a string to a TCP server windows application located on the same machine (host: localhost, port:13000) but when I try to connect the client I had this exception:

{"No connection could be made because the target machine actively refused it"}

Here is my TCP Client code to send data to the server

 

try
   {
    // Create a TcpClient.
    // Note, for this client to work you need to have a TcpServer 
    // connected to the same address as specified by the server, port
    // combination.
    Int32 port = 13000;
    TcpClient client = new TcpClient(server, port);

    // Translate the passed message into ASCII and store it as a Byte array.
    Byte[] data = System.Text.Encoding.ASCII.GetBytes(message);

    // Get a client stream for reading and writing.
    // Stream stream = client.GetStream();

    NetworkStream stream = client.GetStream();

    // Send the message to the connected TcpServer. 
    stream.Write(data, 0, data.Length);


    // Close everything.
    client.Close();
   }
   catch (ArgumentNullException e)
   {
    MessageBox.Show("ArgumentNullException: "+ e);
   }
   catch (SocketException e)
   {
    MessageBox.Show("SocketException: {0}"+ e);
   }

I am developing it on windows mobile 6.0 professional emulator on Windows 7.0 machine.

Notes:

- I already disabled windows firewall and still don't work.

I need your help please.

Thanks for your Help, yeah I solved the issue by connecting to a remote server not on the local machine, but what about setting the SendTimeOut and ReceiveTimeOut properties of the TCPClient class it raises an exception when I tried to set them before connecting to the server.
