2,627,769 | 2,627,770 | Beginner exception handling issue | <p>this post is probably a bit different from the usual questions about exceptions in c++. I hope i'm not wasting people's time with my seemingly obvious questions but i'm struggling to understand what i'm about to ask when reaching out to the obvious sources of knowledge before one would directly ask for help in understanding a concept.</p>
<p>My question is this, in c++, how does someone go about handling user input errors, by this specifically i mean when a user is being prompted for an integer and they enter a float or a string/char or vice versa. You know like someone entering their name when being prompted for their age or something.</p>
<p>I'm basically talking about c++'s equivilent to what would be in python something like:</p>
<pre><code>try:
[code to prompting user for an integer.]
exception ValueError:
[code to run if exception is thrown.]
</code></pre>
<p>Now i know i'm probably going to get alot of face-palming because this seems like such a basic concept of programming but i'm having trouble understanding how to go about this in c++.</p>
<p>If one of you awesome guys has the spare time to explain this to me in a way a beginner would be able to understand it would be <strong>hugely</strong> appreciated guys. As this is something i'm getting frustrated with, it should be very simply i would have thought, perhaps my researching skills need work.</p>
<p>Thankyou in advance people and once again i'm very sorry for any time i've wasted with my noob-ass question. But i just want to learn, and would mean alot if someone could help me out here.</p>
<p>Thanks.</p>

5,996,667 | 5,996,668 | clearing doubts about value and reference types | <p>value type variables contain the actual data directly and reference type variables contain the reference to the actual data.</p>
<p>I think of this as: </p>
<p>l.h.s is value type and r.h.s is reference type</p>
<p><img src="http://i.stack.imgur.com/uxyKv.jpg" alt="enter image description here"></p>
<p>on the left hand side, if I copy <code>i</code> into <code>j</code>, a new memory location is filled with same original data (45).</p>
<p>on the right hand side, if I copy <code>k</code> to <code>l</code>, a new memory location is filled with the reference to the object; and this reference points to the actual object in memory.</p>
<p>now, I am confused about this reference type copying. here's a slight different thing:</p>
<p><img src="http://i.stack.imgur.com/CQ8JG.jpg" alt="enter image description here"></p>
<p>Here, the copy on the r.h.s makes <code>l</code> points to same location as <code>k</code>.</p>
<p>My question is <strong>1. "Which one is truer?"</strong> or is there more to it than I imagined?</p>
<p>Also, value types may be allocated on heap, depending upon the how jitter sees it fit, then <strong>2. Can we force a reference type to be allocated on stack?</strong></p>

5,878,049 | 5,878,050 | Is it bad practice to have nested render loops? | <p>I'm porting a game from Ruby to C++. There is a main render loop that updates and draw the content. Now let's say that during the game, you want to select an item another screen. The way it's done in the original code is to do <code>Item item = getItemFromMenu();</code> <code>getItemFromMenu</code> is a function that will open the menu and do have its own update/render loop, which mean that during the whole time the player has this other screen open, you are in a nested render loop. I feel like this is a bad method but I'm not sure why. On the other hand it's very handy because I can open the menu with just 1 function call and so the code is localized.
Any idea if this is a bad design or not?
I hesitated to post it on gamedev, but since this is mostly a design issue I posted it here</p>
<p>edit : some pseudo-code to give you an idea:</p>
<p>The usual loop in the main part of the code:</p>
<pre><code>while(open) {
UpdateGame();
DrawGame();
}
</code></pre>
<p>now inside UpdateGame() i would do something like:</p>
<pre><code>if(keyPressed == "I") {
Item& item = getItemFromInventory();
}
</code></pre>
<p>And <code>getItemFromInventory()</code>:</p>
<pre><code> while(true) {
UpdateInventory();
if(item_selected) return item;
DrawInventory();

<pre><code>Your name:
Your email:
Subject:
Body:
</code></pre>
<p>I have around 2,000 visitors per day and receive about 10 submissions per day, so I don't need anything too fancy. =)</p>
<p><strong>Miscellaneous questions in my head:</strong></p>
<ul>
<li>Is PHPMailer going to better protect my Contact Form from CC: injection (major concern)? I already know the <code>anti-spambot display:none CSS</code> trick.</li>
<li>Will PHPMailer save me the step of having to write an <code>email_validator()</code> function?</li>
<li>Will PHPMailer save me any other time of having to write any custom functions?</li>

2,206,693 | 2,206,694 | Resizing font size in textarea to fit height | <p>I'm trying to do something different than most 'resize' textarea plugins do. I am not trying to resize the actual textarea, but rather the font size in the textarea so that all of the text fits.</p>
<p>I basically want an 'auto' font size for a textarea. The problem lies in the fact that there are two different ways that the font needs to get 'smaller':</p>
<ol>
<li>User presses 'enter' and creates a line break</li>
<li>User enters more text than the width of the textarea, causing it to break down</li>
</ol>
<p>I've seen a few instances of plugins which I've modified that creates a cloned textarea or div with the same styles that you can try to measure the new 'height' and calculate a font size based on this, but it seems to always fail in Safari and Chrome, so I'm guessing the logic is a bit flawed.</p>

Upon clicking a link, this div is shown and the user sees a textbox and button and an option checkbox. Upon submission of the email address, the following code is fired:</p>
<pre><code>$.post("/asynchronous/addEmail.aspx",
{email: $(".emailPopupTextBox").val(), optin: thisOptIn },
function (data) {
$(".emailText").hide();
$(".thankYouText").show();
$('.emailPopupBox').delay(800).fadeToggle(); });
</code></pre>
<p>On return, the contents of the div are hidden (checkbox, button, and textbox) and a welcome message is shown to the user. At first, this was happening too fast and the email popup was just disappearing too fast. So, I added the <code>.delay</code> and now the emailpopup div shows the welcome message, runs the delay and the togglefade runs but instead of just disappearing as it should, it quickly disappears and flashes real quick and stays visible with the thank you message. If I click the link I initially clicked to fadeToggle the div to appear, it simply makes the div flash real quick but will not hide.</p>
<p>EDIT: It seems after the .post that the .fadeToggle no longer functions properly. I am tracking this problem down.</p>

I have read about <code>Parcelable</code>, <code>Intents</code>, and sharing specific data within <code>Activities</code> from the android dev docs (both dev guide and reference).</p>
<p>Here's the scenario:</p>
<p>I have one <code>ListActivity</code> that fills in an object parsing an xml file, it shows a list of values, and when clicked I want to return the object that represents the item clicked to the activity that has called it, for then, call another activity with this object.</p>
<p>I read on how to implement <code>Parcelable</code> but seems not being the way. Implementing <code>Parcelable</code> receives a <code>Parcel</code> for the constructor and then reads the values from it (or at least that was what I understood).

What are peoples thoughts on javascript support, we build applications rather than just websites and are looking to just support javascript enabled browsers as a pre-requisite assuming that most people or companies have javascript enabled.
Do you find most people have javascript? do you monitor the percentage of javascript/non-javascript browsers (I guess this can be done with website stats) and what are the numbers regarding this?</p>

5,296,860 | 5,296,861 | how to re-bind click() event after using "datatables" search | <p>I have a table that I'm displaying using datatables. One of the columns in the table is a checkbox. Checking (or unchecking) the checkbox causes an Ajax event. Like so:</p>
<pre><code><script type="text/javascript">
$(document).ready(function() {
$(".data-table").dataTable({});
$(".my-checkbox").click(function() {
$.ajax(....)
})
})
</script>
<table class="data-table">
<tr>
<td><input type="checkbox" class="my-checkbox"></td>
</tr>
<!-- repeat many times -->
</table>
</code></pre>
<p>This works great on the initial page load, but as soon as I use the "search" box, the change() method is unbound from anything found by search.</p>
<p>Is there an API hook that I can use to re-bind my click() handler to the checkboxes once the search is complete? Or is there a better way?</p>

<p>But don't type out the numbers in order—find a more awesome way!</p>
<p>I can get the numbers to print using a for loop but now I don't know how to replace the numbers with strings. </p>
