Body
The basic idea is that, since you're using asynchronous I/O with the system thread pool, you shouldn't need to check for timeouts via events because you're not blocking any threads. The <a href="http://msdn.microsoft.com/en-us/magazine/cc302334.aspx" rel="nofollow">recommended way</a> to check for stale connections is to call <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms738544%28v=vs.85%29.aspx" rel="nofollow"><code>getsockopt</code></a> with the <code>SO_CONNECT_TIME</code> option. This returns the number of seconds that the socket has been connected. I know that's a poll operation, but if you're smart about how and when you query this value, it's actually a pretty good mechanism for managing connections. I explain below how this is done. Typically I'll call <code>getsockopt</code> in two places: one is during my completion callback (so that I have a timestamp for the last time that an I/O completion occurred on that socket), and one is in my accept thread. The accept thread monitors my socket backlog via <a href="http://msdn.microsoft.com/en-us/library/windows/desktop/ms741576%28v=vs.85%29.aspx" rel="nofollow"><code>WSAEventSelect</code></a> and the <code>FD_ACCEPT</code> parameter. This means that the accept thread only executes when Windows determines that there are incoming connections that require accepting. At this time I enumerate my accepted sockets and query <code>SO_CONNECT_TIME</code> again for each socket. I subtract the timestamp of the connection's last I/O completion from this value, and if the difference is above a specified threshold my code deems the connection as having timed out.

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.
