Guys pls i need help figuring how to make this desktop application connect to the server located in another computer using wireless LAN. The applications( the client and the server) are TCP/IP network programs.
this is an extract from the client and server codes:

from client:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Net;
using System.Net.Sockets;
using System.IO;

namespace TCP_test_client
{
    public partial class Form1 : Form
    {
        const int buffer = 5000;
        const int port = 1759;
        const string LocalHost = "localhost";
        byte[] incoming = new byte[buffer];
        byte[] outgoing = new byte[buffer];
        
        public Form1()
        {
            InitializeComponent();            
        }

        private void connect()
        {
            TcpClient myC = new TcpClient(LocalHost, port);
        }

        private void button1_Click(object sender, EventArgs e)
        {
            string user = textBox1.Text;
            string pass = textBox2.Text;
            string send = string.Empty;

            TcpClient myClient = new TcpClient(LocalHost, port);
            MessageBox.Show("Connected");

            send = "login$" + user + "$" + pass;

            outgoing = ASCIIEncoding.ASCII.GetBytes(send);
            Stream myStream = myClient.GetStream();
            myStream.Write(outgoing, 0, outgoing.Length);

            for (int i = 0; i < incoming.Length; i++)
            {
                incoming[i] = 0;
            }

            myStream.Read(incoming, 0, incoming.Length);
            MessageBox.Show(ASCIIEncoding.ASCII.GetString(incoming, 0, incoming.Length));
    
        }
    }
}

from server:

using System;

using System.Net.Sockets;
using System.IO;
using System.Net;

namespace Conversion_server

    class Program

            const int port = 1759;
            //var ipAddress = new IPAddress(new byte[] { 127, 0, 0, 1 });
            var Ascii = new ASCIIEncoding();
            var incoming = new byte[buffer];
            var outgoing = new byte[buffer];
            string data = string.Empty;
            string[] details = new string[3];
            

            string machineHostName = string.Empty;
            IPAddress[] machineIP = null;

            try
            {
                machineHostName = Dns.GetHostName();
                IPHostEntry ipEntry = Dns.GetHostByName(machineHostName);
                machineIP = ipEntry.AddressList;
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error trying to get local address {0} ", ex.Message);
            }

            // Verify we got an IP address. Tell the user if we did
            if (machineIP == null || machineIP.Length < 1)
            {
                Console.WriteLine("Unable to get local address");
                return;
            }

            var TCP = new TcpListener(machineIP[0], port);
            TCP.Start();
            Console.WriteLine("***** Server Started {0} *****", DateTime.Now.ToShortTimeString());

            Console.WriteLine("Listening on : [{0}] {1}:{2}", machineHostName, machineIP[0], port);

            Boolean exit = true;

            
            while (exit)
            {
                try
                {
                    Socket sock = TCP.AcceptSocket();
                    int count = sock.Receive(incoming, incoming.Length, 0);
                    data = ASCIIEncoding.ASCII.GetString(incoming, 0, count);
                    
                    char[] delimiters = {'$'};
                    details = data.Split(delimiters, StringSplitOptions.RemoveEmptyEntries);

                    Console.WriteLine(DateTime.Now.ToShortTimeString() + " : {0}", details[0]);
                    data = details[0].ToLower();

                    for (int i = 0; i < incoming.Length; i++)
                        incoming[i] = 0;

                    Console.WriteLine("[{0}] *** Username : {1}\n[{2}] *** Password : {3}", DateTime.Now.ToShortTimeString(), details[1], DateTime.Now.ToShortTimeString(),details[2]);

                    if (data.Equals("login"))
                    {
                        if (details[1] == "johnemg" && details[2] == "donhongkong")
                        {
                            outgoing = ASCIIEncoding.ASCII.GetBytes("The user is registered as : Emejulu Tochukwu Valentine");
                            sock.Send(outgoing, outgoing.Length, 0);
                        }
                        else
                        {
                            outgoing = ASCIIEncoding.ASCII.GetBytes("The user is not registered");
                            sock.Send(outgoing, outgoing.Length, 0);
                        }

                        
                    }              
                }
                catch (SocketException sockEx)
                {
                    Console.WriteLine("Generic Exception Message: {0}", sockEx.ToString());
                }
            }       
        }
    }
}

Please someone help me with a way to proceed.
Thanks in advance.
