hellooo everyone,
I am using the Microsoft Visual studio and i have done the first part of C# Server Socket Program,But debugging of Client Socket Program has given this error ('WindowsFormsApplication1.Form1.Dispose(bool)': no suitable method found to override").Kindly help me out.

The Client socket Program is,

using System;
using System.Windows.Forms;
using System.Net.Sockets;
using System.Text;

namespace WindowsApplication1
{
public partial class Form1 : Form
{
System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();

public Form1()
{
InitializeComponent();
}

private void Form1_Load(object sender, EventArgs e)
{
msg("Client Started");
clientSocket.Connect("127.0.0.1", 8888);
label1.Text = "Client Socket Program - Server Connected ...";
}

private void button1_Click(object sender, EventArgs e)
{
NetworkStream serverStream = clientSocket.GetStream();
byte[] outStream = System.Text.Encoding.ASCII.GetBytes("Message from Client$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();

byte[] inStream = new byte[10025];
serverStream.Read(inStream, 0, (int)clientSocket.ReceiveBufferSize);
string returndata = System.Text.Encoding.ASCII.GetString(inStream);
msg("Data from Server : " + returndata);
}

public void msg(string mesg)
{
textBox1.Text = textBox1.Text + Environment.NewLine + " >> " + mesg;
}
}
}

I have a complett messenger program in c# with source:thumbup1: and if you want i send you the source:cool:

What version of Visual Studio are you using?? The problem appears to be with an incorrect call to the Forms Dispose method. This may be due to incorrect including(using) of other namespaces. I've quickly got it to compile with the following:

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.Sockets;
using System.Net;

namespace WindowsApplication1
{
    public partial class Form1 : Form
    {
        private TcpClient clientSocket = new System.Net.Sockets.TcpClient();

        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            msg("Client Started");
            clientSocket.Connect("127.0.0.1", 8888);
            label1.Text = "Client Socket Program - Server Connected ...";
        }

        private void button1_Click(object sender, EventArgs e)
        {
            NetworkStream serverStream = clientSocket.GetStream();
            byte[] outStream = System.Text.Encoding.ASCII.GetBytes("Message from Client$");
            serverStream.Write(outStream, 0, outStream.Length);
            serverStream.Flush();

            byte[] inStream = new byte[10025];
            serverStream.Read(inStream, 0, (int)clientSocket.ReceiveBufferSize);
            string returndata = System.Text.Encoding.ASCII.GetString(inStream);
            msg("Data from Server : " + returndata);
        }

        public void msg(string mesg)
        {
            textBox1.Text = textBox1.Text + Environment.NewLine + " >> " + mesg;
        }

        
     
    }
}

However, make sure that the following is in Form.Designer.cs

        /// </summary>
        /// <param name="disposing">true if managed resources should be disposed; otherwise, false.</param>
        protected override void Dispose(bool disposing)
        {
            if (disposing && (components != null))
            {
                components.Dispose();
            }
            base.Dispose(disposing);
        }

            this.textBox1.Name = "textBox1";
            this.textBox1.Size = new System.Drawing.Size(268, 181);

            this.label1.Text = "Status";
            //

            this.Text = "Form1";
            this.ResumeLayout(false);
            this.PerformLayout();

        }

        #endregion

        private System.Windows.Forms.TextBox textBox1;
        private System.Windows.Forms.Label label1;
        private System.Windows.Forms.Button button1;
    }
}

Also, I'm assuming that you created a textbox,a label, and a button in your graphical form. It should be noted that there are un-handled exceptions in your code that you should handle in case it crashes. I tried running it and got an error with the Socket programming. To be more specific I got an InvalidOperationException from the NetworkStream object in your button1_Click method.

Hope that helps man.

I have a complett messenger program in c# with source:thumbup1: and if you want i send you the source:cool:

No, the Program did not start!!!

[hir@]

Now the Program is giving the following errors:

Error 1 The name 'label1' does not exist in the current context

Error 2 The name 'textBox1' does not exist in the current context

[yoda174]

hy. Try create a label with name label1 and a textbox with name textBox1 then rebuild the project:thumbup1:

[While(!EOF)]

Since you are using Visual Studio you can create them graphically without any programming. However, you may need to change the names like yoda174 said. From your toolbox pane just drag a label and a textbox on the Form Designer. Then in their properties pane just name them label1 and textBox1 respectively. :)

[hir@]

hey guys, i have run the program :) thnx 2 all of you!!

[yoda174]

We are glad that it work:thumbup1:

[hir@]

hey guys i am back again,lols. Both, the client and server programs are running but now i have to made connection between them so that they can communicate, kindly tell me how can i do this without changing the code !!

[yoda174]

Sry...I dont understand please write datails...What do you mean under communicate...etc:thumbup1:
