    <p>I have a .NET 3.5 Windows Service. I'm testing with a small application that just sleeps threads after starting them, for random timespans of 300 to 6500ms. I have various questions about this issue.</p> <ol> <li>Is <code>BackgroundWorker</code> really intended for use just in WinForms applications or is this just nonsense, how exactly is it tuned to this effect?</li> <li>I've read about <code>ThreadPool</code>s in <a href="https://stackoverflow.com/questions/2015768/threading-library-for-multithreaded-windows-service">this question</a> and <a href="https://stackoverflow.com/questions/230003/thread-vs-threadpool">this one</a>. I'm not exactly sure how much it is a problem for me that the threads would last somewhere between half a second and a few seconds. Is this reason enough to look somewhere else?</li> <li>Am I best off just creating the background threads myself?</li> </ol> <p>The real-life service will poll the database for a list of pending requests, execute threads for each of those requests (limited to a certain amount of concurrent threads) and each thread will be checking if some data exists in a database, retrieve it if it does, or download it from a streaming API, store it, and return that data. The downloading would be the part that consumes the most time.</p> <p>I would really like this question to be answered for .NET 3.5 Framework, but if there are better or more efficient ways to accomplish this under .NET 4.0, I would like to read about them too. Links with more info are also very much welcome.</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.
