<blockquote>
<p>pay attention to line endings - PHP uses a native function to parse the input, so a Mac file won't work on Unix</p>

4,011,166 | 4,011,167 | Building an Exception in C# | <p>I have inherited a code-base which uses a compiled logging library. I cannot update the logging library. This library has method that logs details for an Exception. The method takes a single Exception as a parameter. I'm now building a mobile application that will tie into this system. </p>
<p>In this mobile application, I have a block of code that handles uncaught exceptions. I need to log those in the server. But now, I can only pass the details across the network in string format. Because of this, I have a service that accepts an error message, stack trace, and miscellaneous as strings. I need to take these strings and convert them into an Exception so I can pass them to my pre-existing library.</p>
<p>How can I take a message and a stackTrace as strings and bundle them into an Exception? The challenge here is Message and StackTrace are read-only.</p>
<p>Thank you!</p>

487,761 | 487,762 | Jquery how do I add +1 to a number in a table | <p>So I am generating a table with php/mysql, and in this table are numbers in rows. I have a button that when clicked, adds +1 to this number value <strong>in the MySQL database</strong>. The problem is, I have to refresh the page for the new number to show up in the table.</p>
<p>I am attempting to show the new number immediatly through a function on the <strong>success</strong> of the jquery button click event. So essentially I need to identify the HTML generated number in the table, then add +1 to it.</p>
<p>The problem is, the table is generated with a <strong>while</strong> function in php, so each row gets its own ID on the fly.</p>
<p>Hope this all makes sense.</p>
<p>Here is my Jquery code so far.</p>
<pre><code> $('.upArrow').click(function(){
//this is finding the uparrow button that adds +1
var row = $(this).attr('rowid');
$.ajax({
type: "GET",
url: "upArrow.php?id="+row,
cache: false,
async: false,
success: function(result){
//this is tricky part, how do I select the displayed number part of the
// table, then Add 1?
},
error: function(result){
alert('Error, please try again.');
}
});

5,638,527 | 5,638,528 | Whats the best way to bring an already running app to the front in android? | <p>I have two apps that I want to be able to switch between without killing each different activity and without re-launching the activity I want to switch back too. </p>
<p>Lets say I have a edittext in each activity and I want the text that is written to stay in that edittext view so that when this activity is brought to the front again it's still there.
The problem is that I can't use savedinstancestate, shared preferences or a database to store the information. It should just be there while the application is running. So if it's killed in the background and the info disappears it's no problem.</p>
<p>So what could be the best way of switching between two running applications within these two applications?</p>

2,909,196 | 2,909,197 | Modying Properties of a Class | <p>Finding a suitable question title and -tags for this question struck me rather hard.</p>
<p>Basically I've built a game wherein several units/mobs will be present. Now I'm interested in building a system, so each unit can have effects/buffs/debuffs applied to them that will modify the properties of the unit. Examples of such effects could be a frost effect that'd slow the movement speed of the unit, a health boost and so forth. The plan was to have these effects implemented via scripting so it would be possible to create custom user effects.</p>
<p>I'm looking for advice on how I could implement this. For now I've thought about creating a effect class. Then each applied effect would be an instance of the class, and would have a reference to the unit it was applied to. The effect would have at least two methods, an apply and unapply method for respectively applying- and unapplying.</p>
<p>The problem with this, is that it doesn't allow for different ways of cumulative percentages. Like, should two times 10% increase on a value 100 equal 120 or 121.</p>
<p>Not that it really matters, but it's being coded in C#</p>

<pre><code>def princess_lives_here():
#<some messages and conditionals to keep you going in the text-based game>
#<one of the conditionals end in a `return 'death'`, another function in ROOMS>

'death': death,
'princess_lives_here': princess_lives_here,

next = start
while True:
room = map[next]
print "\n--------"
next = room()
runner(ROOMS, 'princess_lives_here')
</code></pre>
<ol>
<li><p>What I am not sure about is how <code>princess_lives_here</code> is ever run in the while loop. I can only assume that it is run is the last line, but what looks like an assignment to me must be an execution of <code>room()</code>, i.e. <code>princess_lives_here</code>. Why, when and how is this execution performed?</p></li>
<li><p>My second question is how, when, and why the while loop is run again, when the parsing routines hits <code>return 'death'</code>.</p></li>
</ol>

I'm trying 2 make an image "sliding" gallery, but it is a little complicated.
it has 2 have 3 or 5 "views" the mainview ( the one you are currently watching) a previous and a next.
The previous and the next must dynamically load images and unload them when they are 2 positions out of view.</p>
<p>So what it comes down to, i have 150 images i want to display in a sliding gallery and i only want to load 5 at a time if i scroll 2 the right image one should be unloaded and image 3,4,5 and 6 should be loaded and image 2 should be displayed.
I have no real experience with Javascript.</p>

<p>According to the documentation for <code>.data()</code>: </p>
<blockquote>
<p>Every attempt is made to convert the string to a JavaScript value
(this includes booleans, numbers, objects, arrays, and null) otherwise
it is left as a string. To retrieve the value's attribute as a string
without any attempt to convert it, use the attr() method</p>

<p>This is true for jQuery 1.7.2, but 1.8.2 does not do the conversion. Is this the new expected behavior?</p>

173,175 | 173,176 | How to skip using __autoload? | <p>I have a php file which has multiple classes in it. I noticed that __autoload is being called when I instantiate any of the classes, even after the 'package' file has been autoloaded. This is worrying me, because surely if the initial 'package' .php file has been loaded, it is unnecessary overhead for __autoload when the classes have already been loaded. </p>
<p>I probably made a hash of explaining that, so here is an example:</p>
<pre><code><?php
class Class1{};
class Class2{};
?>
</code></pre>
<p>Then in another file:</p>
<pre><code><?php
new Class1;
new Class2;
?>
</code></pre>
<p>__autoload will be used for both Class1 AND Class2's instantiation... even though they are housed in the same file.</p>
