<p>Redirect stops working. PHP outputs nothing. The file gets deleted from the FTP directory. But the redirect completely fails.</p>
<p>If I put an <code>echo</code> inside the if statement when there is an unlink present (before or after any other line of code in the if statement, it outputs nothing.</p>
<p>There isn't an unlink error, and the file is clearly deleted when I check FTP, so what is going on here?</p>

<p>We have a fairly large solution with lots of aspx-files. All aspx-files reside in one Web Application Project. This single big WAP needs to be split in multiple smaller projects. The exact reasoning is beside the point, please believe me ;-).</p>
<p>There are a number of ways to accomplish this, but I am still unsure what the best way would be. We use ASP.Net 4.0 and Visual Studio 2010 Premium.</p>
<p>Any advice is greatly appreciated.</p>
<p><strong>This is our current work-around (which we do not like)</strong></p>
<ol>
<li>Create a WAP (Runner).</li>
<li>Create a second WAP (ProjectA)</li>
<li>Create a third WAP (ProjectB)</li>
<li>Delete the web.config's in ProjectA and ProjectB</li>
<li>Create a simple aspx-file in Runner, ProjectA and ProjectB with a hello world message</li>
<li>Remove ProjectA and ProjectB</li>
<li>Go to Windows Explorer</li>
<li>Move the folders ProjectA and ProjectB inside the folder Runner</li>
<li>Go back to Visual Studio</li>

4,971,316 | 4,971,317 | onCreate not getting called for first activity when calling startActivity consecutively for two different activities | <p>I have three activities <strong>A</strong>, <strong>B</strong>, and <strong>C</strong>.</p>
<p>In <code>onCreate()</code> of A, I call <code>startActivity(...)</code> in two consecutive statements for launching B & C. But android does not calls <code>onCreate()</code> on activity B instantly.
Instead when I press back on C since it is on top of stack. it calls <code>onCreate()</code> on B and the other lifecycle methods then.</p>
<p>Here is what my example code looks like.</p>
<pre><code>public class A extends Activity {
@Override

super.onCreate(savedInstanceState);
startActivity(this, B.class);
startActivity(this, C.class);
}
}
</code></pre>
<p>Any clues to why the call to onCreate of activity B is getting deferred ?</p>

<p>I want to use Jeff Sharkey's SeparatedListAdapter to build a sectioned list. For the list items though, I need to use my custom Employee objects for the items instead of just lists of Strings.</p>
<p>In the included examples for the SeparatedListAdapter, he uses an <code>ArrayAdapter<String></code> and a <code>SimpleAdapter()</code> for populating the list.</p>
<p>Is there any way to use a custom object/class, like my Employee class? The reason I'm needing to do this, is that when I click on an item in the list, I want to retrieve the actual Employee object that I used for that item and then retrieve the ID of the employee so I can display information pertaining to that Employee.</p>
<p>I'm a little bit confused on how to use Adapters properly. Should I make my own adapter or something?</p>

3,045,068 | 3,045,069 | C++, how many years experience? | <p>As a little background, I've been programming for a long time now using various languages, systems, etc.</p>
<p>I've come across the old problem of a recruiter wanting to know "how many years experience" I have of C++. I'm a little stumped as I've bounced around it many times over a number of years. I don't think I can just add up the months/years. I'd put myself somewhere around the 3 - 5 year mark. I know it's a bit of a wide range, but I'm not really sure, with newer standards and libraries, the older stuff probably becomes deprecated.</p>
<p>So, I wanted to ask your opinion. What would you expect a C++ programmer with (i) 3 years, and (ii) 5 years experience (mainly on Unix/Linux systems) to be able to do?
Perhaps, more importantly, what would be the difference you would expect to see between a programmer of 3 years compared to 5 years (and above)?</p>
<p>I know this is all a bit vague and the correct answer is, "it depends". But if anyone has a good opinion, I'd love to know.</p>

I'm really close and there have been a lot of posts here at stackoverflow which have been immensely helpful. Here is what I have so far... </p>
<pre><code><script type="text/javascript">
$(document).ready(function () {
BloggerImporter.getPosts();
});
var BloggerImporter = {
getPosts: function () {
var feedURL = "http://blog.mild.net/feeds/posts/default";
var paras = {
alt: 'json-in-script'
};
$.ajax({
url: feedURL,
type: 'get',
dataType: "jsonp",
success: BloggerImporter.onGotPostData,
data: paras
});
},
onGotPostData: function (data) {
var feed = data.feed;
var entries = feed.entry || [];
var filteredEntries = $.grep(entries, function (value) {
return value.category == 'Mild.Net'
});
$("#blogTemplate").tmpl(filteredEntries).appendTo("#posts");
}

<p>Now, the problem is that each entry can have more than one category. So, in that jQuery grep function above, "category" is an array of objects, where each object has a "term" property. I need to filter by that "term" property, returning all the entries where that term property equals "Mild.Net".</p>
<p>How do I do that?</p>

<p>So suddenly string variable with a value of "True" is not equal to a "True" string literal. I'm lost. How is it possible? What am I missing here? </p>

<p>The best answer seems to be just don't. Here's what I'm thinking thought:</p>
<p>kick off the initialisation via a registration class that implements a certain interface. If a DoSomething gets called, and T is in an assembly we haven't seen before, then we search for a class with the given IRegistration interface. </p>
<p>So... that would get rid of the dependency. It'd use reflection. We'd have to look up the types assembly home each time a method got called, but not too high a price to pay perhaps</p>
