POIs there a way to enforce an atomic operation with no context switch in c#?

    <p>I have several lines of a method that I would like to ensure that there is no context switch to another thread while executing these? Yes, re-architecting is an option but it would be far more expedient for now if I could do this.</p> <p>Is this possible? If not then does anyone know the reasoning behind the decision?</p> <p><strong>Edit:</strong> The reason I am asking is that I have a class responsible for returning a value, the value is provided via an event so when GetValue() is called, the thread needs to block until the event is raised. So we have:</p> <pre><code>public class ValueResolver { IPersistentNotifier _notifier; IValueMonitor _monitor; Value _value; ManualResetEvent _resolvedEvent = new ManualResetEvent(false); public ValueResolver(IPersistentNotifier notifier, IValueMonitor monitor) { _notifier = notifier; _monitor = monitor; _monitor.ValueAcquired += ValueAcquired; } public Value GetValue() { _value = null; persistentNotifier.Show("Getting Value") _monitor.Start(); _resolvedEvent.WaitOne(60000, false); return _value } public void ValueAcquired(Value val) { _value = val; _monitor.Stop(); _notifier.Hide(); _resolvedEvent.Set(); } } </code></pre> <p>Only way I can think of writing a test for this is something like (in rhino mocks)</p> <pre><code>var monitor = MockRepository.GetMock&lt;IValueMonitor&gt;() monitor.Expect(x=&gt;x.Start()).Do(new Action(() =&gt; { Thread.Sleep(100); monitor.Raise(y=&gt;y.ValueAcquired, GetTestValue()); }); </code></pre> <p>but any suggestions are welcomed.</p>

    1. COIs there a typo in the signature for the constructor? I would have thought that the abstract type IPersistentNotifier would be passed in rather than PersistentNotifier (which I assume is a reification of IPersistentNotifier).

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.
