I am learning OOP with PHP. I am creating a class to extract XML data from a website. My question is how do I stop the given object from executing more methods if there is an error with the first method. For example, I want to send the URL: class GEOCACHE { public $url; public function __construct($url) { $this->url=$url...
In this code I see the following lines before the "main" method: JTextArea displayArea; JTextField typingArea; I wonder what these lines do and when they are executed. As far as I know the "main" method is the "entry point". So, the code will be executed from the beginning of the "main" method. All other methods will be executed if th...

Hi I've been trying to use a silverlight client to call an asp.net wcf service that would return a Dictionary. That worked fine when the values in the dictionary were simples types like int, string or Guid. However, I now have a scenario where I need one of the values to be an array of dictionary ! It all compiles fine and the signature...

Hi, I'm currently programming an interface between some C++ code and Java using JNI. I'm getting some events in my GUI that I want to pass to a C++ event handler. I therefore call a function that I wrote in Java. public void sendToEventQueue( AWTEvent evt ) { Mudkiptz.Main.fctC_sendEvent( evt ); } This method is in an abstract cl...

I found this code sample which explains a bit about what I need to do. for (int i = 0;i<empArray.Length;i++) { empArray[i] = new Employee(i+5); } But what happens if I pass more than one parameter into my construc...
Hi folks ! I'm trying to design an application (in C++ but that doesn't matter I guess, anything object-oriented would work the same) which has to synchronize a bunch of events together. Basically, you would have a several data structure instances which would contain lists of events. An event would have a timestamp and be "runable". T...

I have a huge amount of PHP objects for a neural network for which I have to iterate over and perform some maths on. I was wondering if I would be better off using an associative array over instances of classes? I am dealing with around 3640 objects and iterating around 500 times (at best) on top of that so any micro-optimization helps ...

Hi there, I'm trying to create a video player in AS3 that displays the player controls when the user hovers over the video, however I'm having a hard time getting the MOUSE_OVER event to fire. I've made sure that the video's index is at the top, so that's not the issue. Is there something I'm missing? Is there any reason why this event ...
The other day I thought I saw an object iterator in jQuery that had a flag that could be set to recursively iterate over child objects. I thought it was part of jQuery.each(), but now I don't see that capability in the docs. Is there any such iterator in jQuery that can be automatically recursive? (I know how to do it in javascript.
