    <p>I want to broadcast live data from one server to multiple clients using <code>Socket</code>.<br> However, I'm running into concurrency issues with my current implementation.</p> <pre><code>public class Connection { private volatile bool readyToSend; private Queue&lt;byte[]&gt; q; private object bufferMonitor; public Connection { // initialize all things etc and connect } [...] // some other functions which are irrelevant for this problem private void ClientConnected (SocketAsyncEventArgs args) { // called by Thread A [...] readyToSend = true; WaitingForResponse(args); } private void WaitingForResponse (SocketAsyncEventArgs) { // called by Thread A if (q.Count == 0) { lock (bufferMonitor) { Monitor.Wait(bufferMonitor); } } if (q.Count != 0) { byte[] data; lock (q) { data = q.Dequeue(); } args.SetBuffer(0, data.Length); args.ConnectSocket.SendAsync(args); // Will send all bytes and recall to WaitingForResponse afterwards } else { // Will recall this function if nothing happened. } } internal void SendIfConnected (byte[] data) { // called by Thread B if (readyToSend) { lock (q) { q.Enqueue(data); } lock (bufferMonitor) { Monitor.PulseAll(bufferMonitor); } } } } </code></pre> <p>The problem with this implementation is simply, that the change to <code>readyToSend</code> when a client connects is not visible in the second thread - the second problem is, that if you put a breakpoint in the <code>SendIfConnected</code> function and change the value manually to true, that the <code>Monitor.Wait()</code> will never return although Monitor.PulseAll is executed.</p> <p>Also, I kind of think that there should exist some easy solution to my original problem and that the whole idea of using a byte[] Queue for a live broadcast isn't the best one. I would appreciate any point into some better direction.</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.
