    <p>If you use <code>lock (model)</code>, it doesn't mean that other threads won't be able to access <code>model</code>. What it means is that two threads won't be able to execute a section protected by <code>lock (model)</code> at the same time. Because of this, you could use something like <code>lock (model)</code> to protect access to <code>score</code> too.</p> <p><strong>But</strong> that wouldn't work in this case. <code>lock</code> doesn't lock on a variable, it locks on an object and you modify which object <code>model</code> refers to in the loop. Because of that, I thin the best option here is to create another object and lock on that:</p> <pre><code>object model; int score; object modelLock = new object(); Parallel.For(…, (…) =&gt; { int tempScore=0; Object tempModel=getModel(); //some interesting stuff modifying value of tempScore lock (modelLock) { if(tempScore &gt; score) { score=tempScore; model=tempModel; } } }); </code></pre> <p>If you find out that this is too slow for your needs (because using <code>lock</code> does have some overhead, which might be significant for you), you should consider using something like <a href="http://msdn.microsoft.com/en-us/library/system.threading.thread.volatileread" rel="nofollow"><code>Thread.VolatileRead()</code></a> or <a href="http://msdn.microsoft.com/en-us/library/system.threading.interlocked.compareexchange" rel="nofollow"><code>Interlocked.CompareExchange()</code></a>. But be very careful with them, because it's very easy to make your code subtly wrong.</p>

    1. COThanks, a lot! Looks like VolatileRead was exactly what I was looking for, and it works!

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
