    <p>I have simple one-producer/two-consumers code as follows but the output shows that only <code>C2</code> is consuming. Are there any bugs in my code? </p> <pre><code>class Program { static void Main(string[] args) { Object lockObj = new object(); Queue&lt;string&gt; queue = new Queue&lt;string&gt;(); Producer p = new Producer(queue, lockObj); Consumer c1 = new Consumer(queue, lockObj, "c1"); Consumer c2 = new Consumer(queue, lockObj, "c2"); Thread t1 = new Thread(c1.consume); Thread t2 = new Thread(c2.consume); t1.Start(); t2.Start(); Thread t = new Thread(p.produce); t.Start(); Console.ReadLine(); } } public class Producer { Queue&lt;string&gt; queue; Object lockObject; static int seq = 0; public Producer(Queue&lt;string&gt; queue, Object lockObject) { this.queue = queue; this.lockObject = lockObject; } public void produce() { while( seq++ &lt;15) //just testinng 15 items { lock (lockObject) { string item = "item" + seq; queue.Enqueue(item); Console.WriteLine("Producing {0}", item); if (queue.Count == 1) { // first Monitor.PulseAll(lockObject); } } } } } public class Consumer { Queue&lt;string&gt; queue; Object lockObject; string name; public Consumer(Queue&lt;string&gt; queue, Object lockObject, string name) { this.queue = queue; this.lockObject = lockObject; this.name = name; } public void consume() { string item; while (true) { lock (lockObject) { if (queue.Count == 0) { Monitor.Wait(lockObject); continue; } item = queue.Dequeue(); Console.WriteLine(" {0} Consuming {1}", name, item); } } } } </code></pre> <p>The output is:</p> <pre class="lang-none prettyprint-override"><code>Producing item1 c2 Consuming item1 Producing item2 c2 Consuming item2 Producing item3 c2 Consuming item3 Producing item4 c2 Consuming item4 Producing item5 c2 Consuming item5 Producing item6 c2 Consuming item6 Producing item7 c2 Consuming item7 Producing item8 c2 Consuming item8 Producing item9 c2 Consuming item9 Producing item10 c2 Consuming item10 Producing item11 c2 Consuming item11 Producing item12 c2 Consuming item12 Producing item13 c2 Consuming item13 Producing item14 c2 Consuming item14 Producing item15 c2 Consuming item15 </code></pre>

    1. COCould you describe what exactly you are trying to achieve? Your example looks a bit contrived, so I can't determine from context what you need to do.

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.
