<p>First off, this is part of a web app for iOS.</p>
<p>Okay, I have a list of items:</p>
<pre><code>Room Type: <select id="isoList" name="isoList">
<option></option>
<option value="20">ISO 8 Life Sciences Low Use</option>
<option value="25">ISO 8 Life Sciences Med Use</option>
<option value="30">ISO 8 Life Sciences High Use</option>
</select>
</code></pre>
<p>I need to have the user select the room type, then pass the option value - as a var - to another function that uses the var in a calculation.</p>
<p>Here's the script I have to far. My form is named airflow...</p>
<pre><code>function isoChange()
{
var isoChange = document.airflow("isoList");
var airChanges = isoChange.options[isoList.selectedIndex].value;
}
</code></pre>
<p>Now I want to pass airChanges to this function...</p>
<pre><code>function calcAF(airChanges)
{
var length = document.airflow.length.value; //length
var width = document.airflow.width.value; //width
var height = document.airflow.height.value; //height
var changes = airChanges; // hourly air changes
}
</code></pre>
<p>From there the calcAF function will use the var in various math formulae.</p>
<p>I've got it to work if I get the user to tell me airChanges, but it breaks when I try to get the airChanges from a drop down list.</p>

<p>We have access to the server running IIS, we have the API on the fulfillment provider side to send this data over HTTPS, and we can build a simple polling ASP.Net app that runs on the same PCI-certified server that holds the CC data that moves data from Volusion to the fulfillment provider securely.</p>
<p>What remains is how to get the data out of Volusion. We've had several answers and none have panned out:</p>
<ul>
<li>Use the API. The API documentation is very light, and doesn't make clear how to get CC data out.</li>
<li>Fill out a verification form and you can "view" it. This came from their customer service department, but they were very shaky on details.</li>
<li>Query the database directly. It's not clear whether this is feasible.</li>

<pre><code>if( isset($_GET['var']) && is_numeric($_GET['var']) )

<pre><code>function setAndNum($var)
{
if(isset($var) && is_numeric($var))
return 1;
else
return 0;

2,980,321 | 2,980,322 | Achieving easing functions with smaller values | <p>I am using some easing functions in C# which give <code>Ease In</code> and <code>Ease out</code> effects. However, what I am trying to achieve with these easing functions does not give an observable effect.</p>
<p>For eg:</p>
<pre><code>int x=2;
while(x<200)
SetSomething(x = EaseIn(x, 1, EasingType.Quadratic));
</code></pre>
<p>The speed with which SetSomething executes doesn't give enough time to notice the effect of <code>SetSomething</code>. For eg: The value starts from 2 -> 4 -> 16 -> 256</p>
<p>I was trying to achieve the following kind of graphs, but with smaller values (not greater than 200):
<a href="http://theinstructionlimit.com/wp-content/uploads/2009/07/easing.png" rel="nofollow">http://theinstructionlimit.com/wp-content/uploads/2009/07/easing.png</a><br/></p>

<p>Even if I get the quadratic values in a smaller range < 200, I need atleast a very small pause-like effect in each iteration of the loop to notice the effect easing. This small pause can also be follow a quadratic curve (i.e for easing: the pause duration might be more first and then lesser pause durations)</p>
<p>What should I do for the same? How do I get quadratic graph in range < 200 and this pause like effect in each iteration?</p>

3,017,915 | 3,017,916 | How does PHP Work? | <p>We have all seen many question on StackOverflow that are founded upon the idea that PHP works like Javascript. Where the person clearly does not understand that PHP is a <em>Preproccessor</em> and only works before the page is sent out. </p>
<p>A clear example of this is in the following code, where <code>runCommand()</code> will not run when the user presses the button.</p>
<pre><code><a href="<?php runCommand(); ?>">Click Me!</a>
</code></pre>
<p>as it would in Javascript</p>
<pre><code><a href="javascript:runCommand();">Click Me!</a>
</code></pre>
<p>I've seen many questions like this that are from new people that just simply don't realize 'how' PHP works. </p>
<p>My question is: <strong>Where is a great resource that explains how PHP works?</strong>. </p>
<p>I want to be able to redirect people to a page that can get them going on the correct track and know what being a <em>Preproccessor</em> means.</p>
<p><em>(This also allows me to be lazy and not have to write an explanation every time it comes up, but don't tell anyone!)</em></p>
<p>If you don't know of a place that describes this well, feel free to provide your own interpretation.</p>
<p>As <strong>Carl Smotricz</strong> points out, there is a part of PHP that can be used outside of the browser. But I'm mainly talking about in a Apache enviorment where a user requests a web page, and expects to get something back, usually in HTML.</p>

<p>Hi,
Just moved job and I make large use of var.
Previous job we were doing lots of TDD and using resharper.</p>
<p>In this job they hate third party tools and the developers there say that var is not good to use all the time and is not as efficient.</p>
<p>Some time ago I thought the same but now I got so used to it and makes my code look neater.</p>
<p>I have read some posts and there seems to be confusion whether is as efficient or not.
I read that produces the same IL code.So should be the same no? somewhere else I read that even though produces the same IL code it has to find out what type it is.
So what does Inferred really mean then?</p>
<p>Some clarification whether performance wise is the same would be fantastic.</p>
<p>Thanks a lot</p>

4,160,819 | 4,160,820 | Access Control for objects | <p>Is it Possible to limit the functionality of class to certain objects only (in C++). What that would mean is, suppose there are 10 methods in a class and this class has 10 objects. Is it possible to have object1 & object2 access only 3 functions.
Object3, object4,object5, object6 access 6 functions.
and rest of the objects access all functions?</p>
<p>I am trying to implement an access control system, where general users can see only some limited functionality. Previlaged users can have little bit more access and administrators have access to all functions. </p>
<p>One approach is to use inheritance, something like this:</p>
<p>class PublicFeatures
{
public:</p>
<p>// add some methods here;
};</p>
<p>class ProtectedFeatures:public PublicFeatures
{
public:</p>
<p>// add some more methods here;
};</p>
<p>class AdminFeatures:public ProtectedFeatures
{
public:</p>
<p>// add rest of the methods here;
};</p>
<p>In this case, we instantiate objects of any of three classes depending on the kind of access level we want. But what i am thinking is having just one class, and somehow restrict the access to some methods for that particular object.</p>
<p>Is it possible to do such a thing? or i have to follow a different approach for implementing access control?</p>

Points to the following line of code: <code>typedef struct _TTF_Font TTF_Font;</code> in SDL_ttf.h.</p></li>

<p>I've narrowed it down to the following files in a new test project: </p>
<p>Foo.h:</p>
<pre><code>#ifndef FOO_H
#define FOO_H
struct TTF_Font;
class Foo
{
TTF_Font* font;
};
#endif // FOO_H

<p>Foo.cpp:</p>
<pre><code>#include "Foo.h"

Foo a;
return 0;
}
</code></pre>
<p>Do you guys know what I'm doing wrong?</p>
<p>My goal is to forward declare TTF_Font, so I can use it in my header file without including the SDL_ttf header file. I read that including header files in other header files was kinda bad practice, so I switched to forward declarations. All my other forward declarations work fine except this single struct.</p>
<p>When I replace the forward declaration <code>struct TTF_Font;</code> with the header include <code>#include "SDL/SDL.ttf.h"</code>, it compiles without errors. So I can use that, but I want to know WHY, dammit :-).</p>
<p>Extra info: I'm using the Code::Blocks IDE with mingw32 compiler. Project uses the SDL graphics library. Not much C++ experience yet, come from C# background.</p>
