    <p>Before people suggest it: <strong>I am not using Thread.sleep for <em>anything</em></strong> except trying to find a way to work around it. I am trying to handle other people's future code which may not be .Sleep() free. I have a very good grasp of how horrible it is for synchronizing things.</p> <p>I accept a thread in a chunk of my code. I wish to be able to set a limit to this thread's lifetime. My usual method of doing so goes like this:</p> <pre><code>Thread outer = new Thread(() =&gt; { externalThread.Start(); externalThread.Join(); }); outer.Start(); outer.Join(lifetime); if (outer.ThreadState != ThreadState.Stopped) { outer.Abort(); } inner.Join(); </code></pre> <p>I've since discovered that I apparently cannot wake a sleeping thread before the sleep finishes. To make matters worse, this still writes to the console if I give it a lifetime of 10 milliseconds:</p> <pre><code>new Thread(() =&gt; { Thread.Sleep(2000); Console.WriteLine("second"); }) </code></pre> <p>Though I realize .Abort() isn't a hard-limit on thread execution. It seems 2 seconds would be enough of a warning, but I guess not...</p> <p>I've tried checking for WaitSleepJoin status, and .Interrupt(); it crashes the thread, or throws an exception (sorry, unsure which. Windows tells me it crashed if no debugger's running, and if it is running it runs as if interrupt wasn't called), and still writes to the console after 2 seconds. .Resume() apparently does nothing to a sleeping thread.</p> <p><em>Is</em> there a way to wake a thread, without waiting for its Sleep to expire? I understand that stopping isn't "immediate", so that Console.WriteLine may be called regardless; it's the 2 second wait that's bugging me. What if it's a 10 day wait? Since I can't control the threads that come in, I have no way of knowing, and it seems no way of <em>preventing</em> such a thing...</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.
