    <p>I am tired to figuring out what wrong with my code... Please help me out here!</p> <p>I am trying to create a TCP connection between server client in LAN. What happens is, that the program crashes when client tries to connect. Please see the code:</p> <pre><code>public void Go() { if (whatjob == true) { IPEndPoint server_ipEndPoint = new IPEndPoint(IPAddress.Any, PortNum); server_socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); server_socket.Bind(server_ipEndPoint); try { server_socket.Listen(1); server_GotClient = server_socket.Accept(); } catch (SocketException e) { MessageBox.Show("Unable to listen..."); MessageBox.Show(e.ToString()); } reading = new Thread(new ThreadStart(this.get_msg)); reading.Start(); } if (whatjob == false) { IPEndPoint client_ipEndPoint = new IPEndPoint(IPAddress.Parse(IpAddress), PortNum); client_socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); try { client_socket.Blocking = true; client_socket.Connect(client_ipEndPoint); //here it stops execution //client_socket.BeginConnect(client_ipEndPoint, new AsyncCallback(NowConnected), client_socket); } catch (SocketException e) { MessageBox.Show("Unable to connect..."); MessageBox.Show(e.ToString()); return; } reading = new Thread(new ThreadStart(this.get_msg)); reading.Start(); } </code></pre> <p>whatjob is bool... true means do server job and false means do client job</p> <p>this function is inside windows FORM for chat window. when it reaches until client_socket.connect(ipendpoint), it crashed and even chat window is deformated...</p> <p><strong>Threaded Function</strong></p> <pre><code>public void get_msg() { byte[] byte_message = new byte[1000]; string string_message = null; int x = 0; while (true) { if (server_GotClient != null) { x = server_GotClient.Receive(byte_message); } if (client_socket != null) { x = client_socket.Receive(byte_message); } if (x != 0) { string_message = Encoding.ASCII.GetString(byte_message); this.richTextBox_GetMessage.Invoke(new MethodInvoker(delegate { richTextBox_GetMessage.Text = richTextBox_GetMessage.Text + "\nFriend: " + string_message; })); } x = 0; } server_socket.Close(); } </code></pre> <p>Please help regarding this code. to add further, I have no knowledge of asynchronous techniques, help me with some easy methods.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
