1,705,296 | 1,705,297 | Inheriting a class with constructor arguments in java | <p>The situation is I want to inherit an object to have a cleaner constructor interface:</p>
<pre><code>class BaseClass {
public BaseClass(SomeObject object){
...
}
}
class SubClass extends BaseClass{
private SubObject subObject = new SubObject();
public SubClass(){
super(new SomeObject(subObject)); // doesn't compile
}
}
</code></pre>
<p>But to do that I need to do stuff before the constructor like in the example above but can't because Java doesn't allow that. Is there any way around this? I'm starting to feel that if your class is designed to be subclassed it should always implement default constructor and provide setters for the values it needs... Sometimes you can get away with this if you create a new object straight into the super constructor as an argument but if you need a reference to the object you created then you are hosed.</p>

4,107,330 | 4,107,331 | How do I set an absolute include path in PHP? | <p>In HTML, I can find a file starting from the <strong>web server's</strong> root folder by beginning the filepath with "/". Like:</p>
<pre><code>/images/some_image.jpg
</code></pre>
<p>I can put that path in any file in any subdirectory, and it will point to the right image.</p>
<p>With PHP, I tried something similar:</p>
<pre><code>include("/includes/header.php");
</code></pre>
<p>...but that doesn't work.</p>
<p>I think that that <a href="http://us2.php.net/manual/en/ini.core.php#ini.include-path" rel="nofollow">this page</a> is saying that I can set <code>include_path</code> once and after that, it will be assumed. But I don't quite get the syntax. Both examples start with a period, and it says:</p>
<blockquote>Using a . in the include path allows for relative includes as it means the current directory.</blockquote>
<p>Relative includes are exactly what I <strong>don't</strong> want.</p>
<p><strong>How do I make sure that all my includes point to the <code>root/includes</code> folder?</strong> (Bonus: what if I want to place that folder outside the public directory?)</p>
<h2>Clarification</h2>
<p>My development files are currently being served by XAMPP/Apache. Does that affect the absolute path? (I'm not sure yet what the production server will be.)</p>
<h2>Update</h2>
<p>I don't know what my problem was here. The <code>include_path</code> thing I referenced above was exactly what I was looking for, and the syntax isn't really confusing. I just tried it and it works great.</p>
<p>One thing that occurs to me is that some people may have thought that "/some/path" was an "absolute path" because they assumed the OS was Linux. This server is Windows, so an absolute path would have to start with the drive name.</p>
<p>Anyway, problem solved! :)</p>

<p>EDIT 1: I will do up the security injection much later, just need to get the syntax right and get the right result. So this is what i have done so far:</p>
<pre><code><?php
require ("connect-comment.php");
$deleteid=$_GET['commentid'];

<p>When I create new projects for most all of the tutorial programs I select Android 2.3.3 as my target.</p>
<p>However, when going through the Google Map Views tutorial I am told to select Google APIs instead of Android 2.3.3 when creating the project. I did this and the map view program works just fine.</p>
<p>But this seems like a binary OR decision; I'm allowed to select one or the other. Does the Google APIs include all that's in the Android 2.3.3 platform? In other words could I just always select Google APIs target for the platform level that I want and it would work?

4,706,655 | 4,706,656 | Javascript "Uncaught TypeError: object is not a function" associativity question | <p>Code is as follows:</p>

test()

function test() {
var postTypes = new Array('hello', 'there')
(function() { alert('hello there') })()
}

<p>This will throw an "Uncaught TypeError: object is not a function". If I wrap the anonymous function call/invocation in another set of parentheses it will execute the alert, but still give me an error. If I put a semi-colon after the "var postTypes" definition then it will completely fine.</p>
<p>I was led to believe that javascript does not require semi-colons, so I'm making a guess that there is some weird associativity rules of function application that I am not fully understanding. I hope someone can give me the answer to why I am getting this error.</p>
<p>Thanks.</p>

3,449,682 | 3,449,683 | How do I change the full background color of the console window in C#? | <p>In C#, the console has properties:</p>
<pre><code>Console.BackgroundColor // the background color
Console.ForegroundColor // the foreground/text color
</code></pre>
<p>These can be used to change the background color of the console, and the foreground, or text, color of the console.</p>
<p>The issue is, when I do something like:</p>
<pre><code>Console.BackgroundColor = ConsoleColor.White; // background color is white
Console.ForegroundColor = ConsoleColor.Blue; // text color is blue
</code></pre>
<p>Now, with the above code, it does indeed turn the text blue and the background white, but it only turns the background of the text white, instead of the entire background white.</p>
<p>Here's an example of what I mean:
<img src="http://i.stack.imgur.com/LGC6i.png" alt="The background only covers the background of the text, not of the entire console window"></p>
<p>As you can see, the white background only displays behind the text, and does not change the color of the entire console window.</p>
