    <p>A better choice if you are using 4.0 is to use a <code>BlockingCollection</code> for that, for older versions use a combination from a <code>Queue&lt;T&gt;</code> and <code>AutoResetEvent</code>. So you will be <strong>notified</strong> when item is added and on the consumer thread and then just consume it. here we are using a push technology where at your current implementation you are using a poll technology "each time you are asking if there is any data".</p> <p>Example: <code>4.0</code></p> <pre><code>//declare the buffer private BlockingCollection&lt;Data&gt; _buffer = new BlockingCollection&lt;Data&gt;(new ConcurrentQueue&lt;Data&gt;()); //at the producer method "whenever you received an item": _messageBuffer.Add(new Data()); //at the consumer thread "another thread(s) that is running without to consume the data when it arrived." foreach (Data data in _buffer.GetConsumingEnumerable())// or "_buffer.Take" it will block here automatically waiting from new items to be added { //handle the data here. } </code></pre> <p>Example: other "lower" versions:</p> <pre><code>private ConcurrentQueue&lt;Data&gt; _queue = new ConcurrentQueue&lt;Data&gt;(); private AutoResetEvent _queueNotifier = new AutoResetEvent(false); //at the producer: _queue.Enqueue(new Data()); _queueNotifier.Set(); //at the consumer: while (true)//or some condition { _queueNotifier.WaitOne();//here we will block until receive signal notification. Data data; if (_queue.TryDequeue(out data)) { //handle the data } } </code></pre>

    1. COWe basically do this already to process the incoming data from the serial port. We encapsulate each reply and put it in a `BlockingCollection`. Then, another thread simply waits for a new reply to come in and then processes it once it gets it. The question here is how to then process it in a way that will allow a second consumer (specific to the reply I get) to wait for that reply.

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.
