    <p>My main concern is with the boolean flag... is it safe to use it without any synchronization? I've read in several places that it's atomic (including the documentation).</p> <pre><code>class MyTask { private ManualResetEvent startSignal; private CountDownLatch latch; private bool running; MyTask(CountDownLatch latch) { running = false; this.latch = latch; startSignal = new ManualResetEvent(false); } // A method which runs in a thread public void Run() { startSignal.WaitOne(); while(running) { startSignal.WaitOne(); //... some code } latch.Signal(); } public void Stop() { running = false; startSignal.Set(); } public void Start() { running = true; startSignal.Set(); } public void Pause() { startSignal.Reset(); } public void Resume() { startSignal.Set(); } } </code></pre> <p>Is this a safe way to design a task in this way? Any suggestions, improvements, comments?</p> <p>Note: I wrote my custom <code>CountDownLatch</code> class in case you're wondering where I'm getting it from.</p> <p><strong>Update:</strong><br> Here is my CountDownLatch too: </p> <pre><code>public class CountDownLatch { private volatile int m_remain; private EventWaitHandle m_event; public CountDownLatch (int count) { if (count &lt; 0) throw new ArgumentOutOfRangeException(); m_remain = count; m_event = new ManualResetEvent(false); if (m_remain == 0) { m_event.Set(); } } public void Signal() { // The last thread to signal also sets the event. if (Interlocked.Decrement(ref m_remain) == 0) m_event.Set(); } public void Wait() { m_event.WaitOne(); } } </code></pre>

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.
