    <p>Lets take the sample class SomeThread where we are attempting to prevent the DoSomething methods from being called after the Running property is set to false and Dispose is called by the OtherThread class because if they are called after the Dispose method is the world would end as we know it.</p> <p>It feels like there is a chance for something evil to happen because of the loop. That at the point where it starts the next loop and before the lock is taken before calling the DoSomething methods, Running could be changed to false, and Disposed called before it hits the lock. In this scenario life would not be good. </p> <p>I was looking at ways to handle this when using a loop in a simple easy to maintain method. For the record I did considered the Double Lock Check patterned, however it is does not seem to be recommend for C#. </p> <p><strong><em>Warning:</strong> This is a simplified example to try to make it easy to focus on the issue with the loop and locking within one. If I didn't elaborate enough some place please let me know and I will do my best to fill in any details.</em> </p> <pre><code>public class SomeThread : IDisposable { private object locker = new object(); private bool running = false; public bool Running { get { lock(locker) { return running; } } set { lock(locker) { running = value; } } } public void Run() { while (Running) { lock(locker) { DoSomething1(); DoSomething2(); } } } private void DoSomething1() { // something awesome happens here } private void DoSomething2() { // something more awesome happens here } public void Dispose() { lock (locker) { Dispose1(); Dispose2(); } } private void Dispose1() { // something awesome happens here } private void Dispose2() { // something more awesome happens here } } public class OtherThread { SomeThread st = new SomeThread(); public void OnQuit() { st.Running = false; st.Dispose(); Exit(); } } </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.
