    <p>I've written a program that takes two images, then runs an algorithm on them to isolate a hand in the "foreground" and match the gesture to a known one.</p> <p>A few days ago, I ran the program with some test parameters, just to test a few tweaks I had made, and it all worked fine. I have not touched the code since then.</p> <p>Today, I ran the program with two new images, and it crashed, giving me the error code <code>0x0</code> and <code>HRESULT=0x80070057</code>. Beyond this, when I stopped debugging from C# Visual Studio 2010 Express, somehow, the debugging stopped, according to studio. But the form is still up, unresponsive, and unable to be closed, even from Task Manager. I can't run the program, because it says another instance is still running.</p> <p>What could be causing this? And what can I try to fix it? I'd be happy to provide any other details that might be helpful; I'm relatively inexperienced and don't really know what is and isn't helpful.</p> <p><strong>Addition:</strong> I stopped and started studio, and that seems to have fixed the problem. Still, if someone can explain what may have happened, it would be much appreciated.</p> <p><strong>Another detail:</strong> The program crashed near the end of what it was supposed to do. I was able to start, load both pictures, and run the algorithm, but in the last step, it crashed on me.</p>

    2. COI don't think It's not a duplicate because this is not ASP.net related.

    3. COIIRC there are one or two error codes (HResults) that are relatively generic, and that is one of them - i.e. it cannot be traced to a specific error. (I used to strike that reasonably frequently back when doing WinAPI on VB6).

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).
