Question

Client-server architecture (client/server) is a network architecture in which each computer or process on the network is either a client or a server. Servers are powerful computers or processes dedicated to managing disk drives (file servers), printers (print servers), or network traffic (network servers). Develop a simple calculator program using client server architecture. Client should accept the input, send It to the server, process/calculate it and send it back to client. Introduction and problem definition Problem solving approach Implementation Results and Analysis Conclusion

Explanation / Answer

Hi here am make a program on window based application in C# only basic calculator for adding of two numbers;

B4.1.:---it basic calculator for adding two integer value in c# which based a window based software using client and server resposne.

B4.2:--Problem solving approach is very simple i.e. only sum of two digit i have made . which is very basic.

B4.3:- Implimention

first a impliment a client side i.e. window input form in which i take value for calculating:

and here i add the code for client side.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using Dll;

namespace client
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
        Class1 obj = new Class1();

        private void button1_Click(object sender, EventArgs e)
        {
            try
            {
                double num1 = Convert.ToInt32(textBox1.Text);
                double num2 = Convert.ToInt32(textBox2.Text);
                ChannelServices.RegisterChannel(new TcpClientChannel());
                obj = (Class1)Activator.GetObject(typeof(Class1), "tcp://localhost:3128/Hello");
                label3.Text = obj.Cal(num1, num2).ToString();
          
            }
            catch(System.Net.Sockets.SocketException)
          
            {
                MessageBox.Show("server not available");
          
            }
        }

      
    }
}

after this i implimented the server side in which i made a console window as server

the code of server side is:-

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;
using System.Runtime.Remoting.Channels.Tcp;
using Dll;
namespace server
{
    class Program
    {
        static void Main(string[] args)
        {
            TcpServerChannel channel = new TcpServerChannel(3128);
            ChannelServices.RegisterChannel(channel);
            RemotingConfiguration.RegisterWellKnownServiceType(typeof(Class1), "Hello", WellKnownObjectMode.SingleCall);
            Console.WriteLine("Press Enter To stop server");
            Console.ReadLine();
        }

    }
}

after this i made class for calculation of two number .i.e. addition method implimentation in this class

the code is:-

using System;
using System.Collections.Generic;
using System.Text;

namespace Dll
{
    public class Class1:MarshalByRefObject
    {
        public double Cal(double a, double b)
        {
            return a + b;
      
        }

    }
}

B4.4 Result:- absolutly fine result we will get;

B4.5:-Conclusion:-

it a basic window based simple calculator program using client server architechure i have implimented.

If u have any doubt or query about this application then please feel free to ask in comment section ...thanks
