<p>I'm trying to select the "name" field from the author node in an ATOM feed using LINQ. I can get all the fields I need like so:</p>
<pre><code>XDocument stories = XDocument.Parse(xmlContent);
XNamespace xmlns = "http://www.w3.org/2005/Atom";
var story = from entry in stories.Descendants(xmlns + "entry")
... | <p>You basically want:</p>
<pre><code>entry.Element(xmlns + "author").Element(xmlns + "name").Value
</code></pre>
<p>But you might want to wrap that in an extra method so you can easily take appropriate action if either the author or name elements are missing. You might also want to think about what you want to happe... | <p>It could be something like this:</p>
<pre><code> var story = from entry in stories.Descendants(xmlns + "entry")
from a in entry.Descendants(xmlns + "author")
select new Story

Title = entry.Element(xmlns + "title").Value,

<p>I have a resource handler that is Response.WriteFile(fileName) based on a parameter passed through the querystring. I am handling the mimetype correctly, but the issue is in some browsers, the filename comes up as Res.ashx (The name of the handler) instead of MyPdf.pdf (the file I am outputting). Can someone inform ... | <p>Extending from Joel's comment, your actual code would look something like this:</p>
<pre><code>context.Response.AddHeader("content-disposition", "attachment; filename=" + resource);
</code></pre>
| <p>Thank you guys for your answer. The final code works and checks for pdf.</p>
<pre><code>if (extensionArray[extensionArray.Length - 1].ToLower() == "pdf")
context.Response.AddHeader("content-disposition",
"Attachment; filename=" + resource);

<p>I'm running into an odd problem with Visual Studio 2005: I have a data breakpoint that's set to run a macro and continue (that is, I select a macro and check Continue Execution.)</p>
<p>Now, instead of silently running the macro when the value in the data breakpoint (tracepoint, really) changes, I first get a messa... | <p>It does this for me as well. The behavior does seem somewhat different based on how you set the "Continue execution" option, so my suspicion is that this behavior (painful as it is) may be by design. Or it may be a bug, but in either case you may be stuck.</p>
<p>An alternative might be to use windbg or one of the ... | <p>I do not have vs.net 2005 on my machine.<br>
So, I am speculating here.<br></p>
<p>What is the line of execution?</p>

Is a conditional breakpoint set when the property is read? (i.e. break when property is read?)<br></p>

<p>I have a List of custom object, which consist of a custom list.</p>

I don't like the idea of moving from a nice clean object to a DataTable, but it provides support for the dynamic binding you need. I modified your friend object to have a few constructors.
