    <p>I read some C# chat source code &amp; I see that: on chat server with a lot of connected clients, server listener will run in a separated thread &amp; each connected client will also run in a separated thread. Code examples:</p> <p>Start server &amp; begin listening in a separated thread:</p> <pre><code> public void StartListening() { // Get the IP of the first network device, however this can prove unreliable on certain configurations IPAddress ipaLocal = ipAddress; // Create the TCP listener object using the IP of the server and the specified port tlsClient = new TcpListener(1986); // Start the TCP listener and listen for connections tlsClient.Start(); // The while loop will check for true in this before checking for connections ServRunning = true; // Start the new tread that hosts the listener thrListener = new Thread(KeepListening); thrListener.Start(); } private void KeepListening() { // While the server is running while (ServRunning == true) { // Accept a pending connection tcpClient = tlsClient.AcceptTcpClient(); // Create a new instance of Connection Connection newConnection = new Connection(tcpClient); } } </code></pre> <p>And a connection will also run in a separated thread:</p> <pre><code>public Connection(TcpClient tcpCon) { tcpClient = tcpCon; // The thread that accepts the client and awaits messages thrSender = new Thread(AcceptClient); // The thread calls the AcceptClient() method thrSender.Start(); } </code></pre> <p>So, if a chat server with 10000 connected clients, the chat server application will have 10002 threads (one main thread, one server thread &amp; 10000 client threads). I think the chat server will be overhead with a big number of threads. Please help me a solution. Thanks.</p> <p><strong>UPDATE:</strong> I believe chat examples are only for learning networking &amp; they are not suitable in real-world model. Please give me a real-world solution. Thanks.</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.
