I'm not the best at this jquery stuff. But I'm trying to seperate the action from the function so I can apply multiple events that cause the same function. Unfortunately this isn't working. Anyone know why? Updated Function, but still errors $(document).ready(function() { var $info_items = jQuery('.checkbox.has_info, .has_info'); $in...

I have recently begun working on a PHP/JS Form Class that will also include a SQL Form builder (eg. building simple forms from sql and auto inserts/updates). I have tried several classes (zend_form, clonefish, PHP Form Builder Class, phorms etc) but as yet haven't come across a complete solution that is simple, customizable and complet...
In Scala I could define an abstract class and implement it with an object: abstrac class Base { def doSomething(x: Int): Int } object MySingletonAndLiteralObject extends Base { override def doSomething(x: Int) = x*x } My concrete example in Python: class Book(Resource): path = "/book/{id}" def get(request): ...
Hi! Is there some library that allows me to easily and conveniently create Object-Oriented callbacks in c++? the language Eiffel for example has the concept of "agents" which more or less work like this: class Foo{ public: Bar* bar; Foo(){ bar = new Bar(); bar->publisher.extend(agent say(?,"Hi from Foo!", ?));...
Possible Duplicate: How to prevent an object being created on the heap? Hi, I heard a concept called as stack based class. I.e. we can’t create instance of the class using new. I am hearing this for the first time. One way to implement this by private overloading of ‘new ’ operator. If anybody know details about the stack...
I might be missing something here, I'm not sure. A Google search didn't really help either. What I'm wanting to do is call the databaseServer class and use its methods within my userControl class. Here is my lib_class.php file: <?php include('definitions.php'); class databaseServer { var $con; var $db; var $close; va...

Let's say that I'm currently designing an application where I will need to use a global timing system (it's a cross-cutting concern). I'll need to access data from that global timing system from basically anywhere in my app and it's not like I can see that "this part of the application will need it while the other won't". My question i...
I have a very limited understanding of OOP. I've been programming in .Net for a year or so, but I'm completely self taught so some of the uses of the finer points of OOP are lost on me. Encapsulation, inheritance, abstraction, etc. I know what they mean (superficially), but what are their uses? I've only ever used OOP for putting reus...

I don't think I am a total noob in OOP, but do you sometimes feel we go a little too far in privatizing the fields? Do you have a good rule of thumb as to when a field absolutely must be private, and when is it (maybe) okay to mark it protected, or public? Sometimes it's the obvious thing that gets me. Discuss ...
Okay, first, here's my rather poor diagram... It's worth noting the "Name Me" class may be listening to more than one RequestNotifier It's safe to assume all Work Items that are put on the Work Queue are taken off the work queue by something else not shown and are processed exactly the same. The only difference between the work items...
I'm writing a poker framework in C# and I don't like the design I currently have. My goal is to have a game engine that can play a multiple AI against each other in batch mode very quickly, play multiple AI vs. multiple humans (probably via a Silverlight client). I'd like to keep efficiency high but maintain game support flexibility-- e....

Hi guys... I was wondering how to do the PHP OOP design pattern for real life application. I wish someone can share their learning experience with me.
