I decided to look at some of the code we had written and noticed that almost all the php documents had the line: <code>require_once('appvars.php');</code> at the top. I know that this isn't a built in php file, but one that they had created. I figure it is probably something that they had copied from a tutorial or beginners book so I assume it is a common practice of sorts. </p>
<p>in short: <strong>what are the contents of appvars.php</strong> and <strong>what is its purpose?</strong></p>
<p>note: The server has been offline for several months now so I don't have access to it and thus can't look at the source its self</p>

5,297,759 | 5,297,760 | iPhone, how to fire a button event in programmatically | <p>I want fire a button event(or maybe method) in code,the button was generate by iPhone SDK , I can not update it, so I add the action to the button, the code likes as follows:</p>
<pre><code>[theButton addTarget:self action:@selector(onButtonEvent:)
forControlEvents:UIControlEventAllTouchEvents];
-(void) onButtonEvent:(id)sender
{
AppTrace2(self, @"onButtonEvent", sender);
}
</code></pre>
<p>and when I tap the button, the app will execute a function that was produce by iPhone sdk, also the new method 'onButtonEvent' will be executed, and then I try to add some code as follows:</p>
<pre><code>[theButton sendActionsForControlEvents: UIControlEventTouchDown];
[theButton sendActionsForControlEvents: UIControlEventTouchDownRepeat];
[theButton sendActionsForControlEvents: UIControlEventTouchDragInside];
[theButton sendActionsForControlEvents: UIControlEventTouchDragOutside];

[theButton sendActionsForControlEvents: UIControlEventTouchUpOutside];
[theButton sendActionsForControlEvents:UIControlEventTouchDown];
[theButton sendActionsForControlEvents:UIControlEventAllEvents];
</code></pre>
<p>but it does not call the original functions which was produced by iphone sdk, although the new method 'onButtonEvent' also was executed when above sendActionsForControlEvents executed ....
my goal is to invoke the original function ... sdk does not provide tip on this , so I have to simulate the tap event to invoke the function to executed .... </p>
<p>any one can give a tip on this problem ?</p>
<p>Thanks for your time!</p>

From Novice to Professional</a>.</p>
<p>I am interested in developing e-commerce websites and I want to do it right since I will also be doing it for other people in the near future (6-8 months from the moment I start). </p>
<p>While I am sure about the first book that will help me achieve what I need for the second I am open to suggestions.</p>
<p>My first problem is that these 2 books won't be enough for what I need. I have no experience in using MVC architecture which seems to be the main architecture these days for writing big and sustainable projects and also no knowledge of any other design pattern which is used these days. </p>
<p>Can anybody recommend a good book or resource for understanding and writing MVC projects and getting familiar with good OOP design patterns?</p>
<p>My second problem is that I am undecided if I should learn a PHP framework immediately or I should try working with it as it is. If I am going to learn a framework, I decided on Codelgniter. Is it a good choice for e-commerce development?</p>
<p>I mostly chose it because it is considered one of the fastest frameworks. I am not seeking to start a holy war on wether is best to use a framework or not what I want is to know if it is a good idea to learn a framework immediately after I learned PHP ? If it is or not a good idea I would like some arguments so I can better decide.</p>
<p>I already decided I will use a framework on some point so I can increase productivity so I am not seeking a debate.</p>

<p>Edit 2: Looking at the IL it seems If your struct exposes Dispose() as public, the compiler calls Dispose when an instance of the struct goes out of scope if you forget to call Dispose() (for example, you are not using the "using" statement)? Sooo it seems most of you guys are wrong !!</p>

<p>I would like to sort the sub category items (which are cities subdivided by state further up in the code.</p>
<p>i thought i could just sort the following array $category->getChildren() but it doesnt work. so i did an echo on it and it said array, so i did var_dump on that array and got a bool(true) on it. when i tried other ways (print_r) of outputting it it crashed the page.</p>
<p>i dont understand arrays very well so could someone explain what is this array that is not an array? how can i sort the city list?</p>
<p>thanks!</p>

2,213,772 | 2,213,773 | Creating objects in for loop. I missing the mark a bit | <p>I would like to have a for loop create objects as the children of a parent object. Usually, I would declare the object without using the for loop like this:</p>
<pre><code> var mObj = {};
mObj.obj1 = {};
mObj.obj2 = {};
mObj.obj3 = {};
mObj.obj3.firstname = "john";
mObj.obj3.lastname = "superfly";
</code></pre>
<p>Now lets say I would like to employ a for loop to create the children objects of a parent object "mObj".</p>
<p>This is where I am going wrong:</p>
<pre><code>var mArr = ["firstname","lastname","email"]; // This array holds the keys for the objects
var mObj = {};
var len = (mArr.length);
for(var i=0; i<len; i++){
var obj+i = {}
mObj = obj+i;
mObj.obj + i.mArr[i] = ""
}
</code></pre>
<p>So the outcome of this would be:</p>
<pre><code> mObj.obj1.firstname = "";
mObj.obj2.lastname = "";
mObj.obj3.email = "";
</code></pre>
<p>I just cannot seem to name the object with counter that is being created within for loop like:</p>
<pre><code>obj1
obj2
obj3
</code></pre>
<p>Any help would highly be appreciated.</p>

839,099 | 839,100 | C++: Problem with overloading mathematical operators | <p>I am looking to overload, let's say, the addition operator and have it add two objects of the same class. When I declare this "operator+" prototype function in the class declaration in the header file, I pass in both objects as parameters. I get a compiler error saying that "binary 'operator +' has too many parameters". I was searching around for an answer online and found out that declaring an inline function just outside the class declaration in the header file compiled out. I'm wondering what I was doing wrong or if I'm missing something here. Here is the code I am using in the header file.</p>
<pre><code>class Person

double weight;
public:
Person::Person(); //default constructor
Person::~Person(); //default desctructor
Person operator+(Person r, Person i);
