    <p>What I want to do is, </p> <ul> <li>to get conversion rate from this website (I have choosen xe.com because it supports needed currencies AZN &lt;-> USD)</li> <li>If it's possible for example to send "5 AZN" and get what it equals in USD. URL looks like this: <a href="http://www.xe.com/ucc/convert/?Amount=5&amp;From=AZN&amp;To=USD" rel="nofollow">http://www.xe.com/ucc/convert/?Amount=5&amp;From=AZN&amp;To=USD</a></li> </ul> <p>I grabbed the following snippet from <a href="http://dickchiang.blogspot.com/2010/02/getting-foreign-exchange-currency-with.html" rel="nofollow">a blog</a>:</p> <pre><code>string xeString = String.Format("http://www.xe.com/ucc/convert.cgi?Amount=1&amp;From={0}&amp;To={1}", srcCurrency, dstCurrency); System.Net.WebRequest wreq = System.Net.WebRequest.Create(new Uri(xeString)); System.Net.WebResponse wresp = wreq.GetResponse(); Stream respstr = wresp.GetResponseStream(); int read = respstr.Read(buf, 0, BUFFER_SIZE); result = Encoding.ASCII.GetString(buf, 0, read); </code></pre> <p>Now, this will return something like <code>XE.com: USD to EUR rate: 1.00 USD = 0.716372 EUR</code> </p> <p>The problems are: </p> <ol> <li>I have no idea what the variables <code>buf</code> and <code>BUFFER_SIZE</code> are. </li> <li>How can I get an exact result, for instance send <code>5 AZN</code> and get the result in USD (as double)? <a href="http://www.xe.com/ucc/convert/?Amount=5&amp;From=AZN&amp;To=USD" rel="nofollow">http://www.xe.com/ucc/convert/?Amount=5&amp;From=AZN&amp;To=USD</a></li> </ol>

    1. COI suggest forgetting about the `WebRequest`/`WebResponse`; use [`WebClient.DownloadString`](http://msdn.microsoft.com/en-us/library/fhd1f0sw(v=vs.80).aspx) or [`WebClient.DownloadStringAsync`](http://msdn.microsoft.com/en-us/library/ms144202(v=vs.80)) instead...

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.
