I need something that will help me with my include_once paths, but $_SERVER[DOCUMENT_ROOT] goes too far down. And if I were to use this, and transfer the website folder later, all my include_once paths will/might break.</p>
<p>Hope my question is clear... Any recommendations?</p>
<p>Essentially, what I'm trying to do is, access classes, that are located in different folders, from different files. When it works for some files, it'll break in others, because of the way I'm writing the include statements.</p>
<p>Ie. class test{include_once '../Data/employee.php';}
A file that will include the class test, will work. But say another file, from a different directory, includes the class test. It'll break. Because the other file can be 3 folders deep, instead of just one.</p>

<li>positive, not 0,</li>
<li>a whole number, but might be bigger than integer size</li>
<li>come as either string or number</li>
</ul>
<p>I'd like to know what you think is the most elegant way of validating this. Candidates that fail are:
- <code>is_int()</code>, because it's valid for negative numbers, AND because of the integer size limit
- <code>is_numeric()</code>, because it'd valid for float, or, say, having an exponential part like this +0123.45e6
- <code>ctype-digit()</code> with casting the input to string, because this would be valid: "0000"</p>

4,216,660 | 4,216,661 | how do I get the viewport position relative to the screen? | <h3>My question</h3>
<p>What JavaScript code will tell me where the <strong>viewport</strong> of the <strong>browser</strong> is located relative to the <strong>screen</strong>?</p>
<h3>Context</h3>
<p>My web application includes an applet that allows taking a snapshot via <em>java.awt.Robot</em> (the applet's jar is of course signed and is privileged to perform this).</p>
<p>The problem is that Robot's <em>createScreenCapture</em> works with rectangles relative to the entire screen, whereas I want to capture a rectangle relative to the viewport.</p>
<p>A browser can obviously be anywhere on the screen, but even if it is maximized (and therefore begins at the top left of the screen, i.e. {0,0}) I still don't know how much the content is pushed down because of the window header or some toolbars.</p>
<h3>My research so far</h3>
<p>It seems only IE gives the viewport position through <em>window.screenTop/Left</em>.</p>
<p>Chrome supports these, but they hold the browser position.</p>
<p>FF doesn't support these, instead it has <em>screenX/Y</em>, but like Chrome they hold the browser position.</p>
<h3>Making sure we all use the same terminology</h3>
<p><strong>Screen</strong> - AKA the desktop. for example I have a WSXGA+ (1680x1050) display. I use Windows and my taskbar is always shown at the bottom so it consumes about 50 pixels vertically.</p>
<p><strong>Browser</strong> - a window that may or may not have various toolbars: address and/or bookmarks bar at the top, status/add-on bars at the bottom, etc.</p>
<p><strong>Viewport</strong> - where a URL is actually being rendered.</p>

<p>When I use list's emplace and put an instance of class A:</p>

<p>On the other hand when I do this:</p>
<pre><code>mylist.emplace(A(2));

<ol>
<li>Why is list's emplace call my non-const copy constructor instead of my move constructor?</li>
<li>Is the non-const copy constructor is actually an alternative way to define a move constructor?</li>
<li>Is this behavior is correct (for a c++0x compiler) or it just VS2010's behavior?</li>

1,324,005 | 1,324,006 | How to time a jQuery game with php | <p>I'm creating a jQuery game where the player has to complete a task in the quickest time possible.
I display a timer so the user knows how long they are taking to complete the task.</p>
<p>I've been reading up on cheating/hacking and it seems the only way to prevent it is to keep the important logic server side. My server side language of choice is php.
As the important logic for my game is the time taken, I can set a timer when the game starts, and stop the timer with an ajax call when the game ends.</p>
<p>I'm just wondering what to do if there is a lag between the ajax call being made and the server receiving the call.
Say the user completes the task in 12 seconds but there is a 1 second lag for the ajax caqll to be recieved.
The value written to the highscore table will be 13 seconds which will make for an unhappy player!</p>
<p>Is the server side timer/ajax call the way to go here? Am I worrying too much about a lag? Is there a better way to go about timing a game?</p>
<p>This is my first ever game so I'm unsure about the best way to stop cheating!</p>

3,631,756 | 3,631,757 | string variable shows wrong length | <p>So I have a function that gets some string variables from a form (after the form is submitted), then runs a query using those variables and returns lines of results.
I have several conditions that work fine, except for one and I can't figure out what's wrong.
When I print out the query and run it in phpMyadmin - it works just fine (returns 3 rows for example), but it doesn't run on the page (shows that 0 rwos are returned).
One thing that I have noticed is that when I do var_dump it gives the correct type (string) but wrong length. trim doesn't make any difference.
So fo example</p>
<pre><code>$name2 = "John Doe";
var_dump($name1);
var_dump($name2);
</code></pre>
<p>The name2 returns string(8)
But when for name1 it returns string(9), even though name1 is also "John Doe" - I have no idea what that extra character is.
That variable is coming from a form, from a select element. Select is populated from a table. I trim resulting POST value before assigning to name1. Character encoding is the same for the table where names in select element are coming from and table on which I run a query.
All other variables from the form are passing fine and query runs correctly if I don't add the name. Again, if I print out the query (with name condition included) and copy and paste into phpMyAdmin - it runs just fine.
I'm going crazy here.</p>

4,616,953 | 4,616,954 | Returning to the Home Screen and then returning to last activity | <p>Having real issue understanding how to sort my issue out.</p>
<p>On the Home screen I have 2 buttons</p>
<p>When the user clicks the first button it starts a new Activity. What I am looking for is if the user clicks back the app returns to the home screen. If the user clicks the first button again it starts a new activity.</p>
<p>If the user clicks the second button it returns to the activity that was last started by clicking button 1</p>
<p>What I am having issue with is how to save the state of the activity when the user clicks back
Also how to call that activity when the second button is pressed</p>
<p>Thanks for your Time</p>
<p>UPDATE</p>
<p>I have gone down part of this but still having issues. If I put some of the code I am using perhaps someone can point where I gone wrong.</p>
<p>Code for calling the new activity from main menu</p>
<pre><code>Intent intent = new Intent(MainMenu.this, NewClass.class);
intent.putExtra("value1", value1);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(intent);
</code></pre>
<p>Within the new class I have added the following :</p>
<pre><code> @Override
public void onBackPressed() {
//super.onBackPressed();
Intent intent = new Intent(RoundScoring.this, MainMenu.class);
intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
startActivity(intent);
Toast.makeText(this, "Back Button Pressed", Toast.LENGTH_LONG).show();
}
</code></pre>
<p>I do not have either a onrestoreinstancestate or onresumne in this class. only a oncreate. Do I have to add something like this to bring back the instance</p>
<p>On the second button on the main menu I have added this</p>
<pre><code>Intent intentContiune = new Intent(MainMenu.this, NewClass.class);
intentContiune.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(intentContiune);
</code></pre>
