hello.
In meta-programming number of classes grows quite fast.
Is maximum number of classes modern compiler allows, for example g++, something to be concerned about?
Thank you
What are the best practices for using Java's @Override annotation and why?
It seems like it would be overkill to mark every single overridden method with the @Override annotation. Are there certain programming situations that call for using the @Override and others that should never use the @Override?
I'm trying to setup something like Aspect Oriented Programming in Actionscript 3, basically the only thing I need to be able to do is something like this:
SomeClass.getMethod("methodName").addEventListener(afterMethodExecuted, function() {
//run code
});
This way I can run code after (or before) any method in any class has run, allowing numerous new possibilities.
How should I implement this?
Please forgive my programming knowledge. I know this is a simple thing, but I do not understand why result is always 0. Why decimal will be fine?
int a = 100;
int b = 200;
decimal c = (a / b) * 100;
Many thanks.
Pretty basic programming question, I know PHP have a function for it, but does the iPhone OS have one?
I want to check if the current indexPath is a value in an array.
PHP Example:
<?php
$indexPath = 3;
$array = array("0", "1", "2", "3", "4");
if (in_array($indexPath, $array)) {
// Do something
}
?>
Does anybody know how to do the same thing inthe iPhone OS?
Hi all!

I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together.
What's a good starting point to understanding what looks like the only rocket-science programming language in the world?
Links to articles, books or anything else that could help me get my grounding would be appreciated.

Thanks.
PHP was the undisputed king of easy webapp development, until Ruby on Rails, Django, and other dynamic programming frameworks appeared. What are, in your opinion, PHP's strengths against the newcomers?
Recently I did a Java programming exercise successfully which was sent by a recruiting firm, The problem statement goes like this 'There are two text files FI(records abt files and directory information) and FS(containing blocks of data) which represent a file Index and file System respectively and I was supposed to write a static read method in a class which will read the file from the FS depending upon the path string provided using FI' My question is where can I get these kind of exercises to solve, the complexity should be above average to tough.
I'm trying to use Eclipse + PyDev for studying OpenGL programming but when I type
from OpenGL.GL import *
from OpenGL.GLUT import *
IDE becomes extremely slow!
Ok. It isn't a smart idea import to much useless things but it's so useful for learning a new library!
Any help?
PS: I use Ubuntu with Eclipse Galileo.
I have a basic html form that adds some data to the page using PHP. I want to make this form field a "Price" field. My html is:
<input class="bids" name="comment" id="comment" tabindex="4" />
How can I fix this field so that users can't enter random letters, dollar signs, dashes, or other weird formats. I want the output to be whole dollars. Sorry I'm a complete programming moron. :)
Is it practically possible to create a triangle of stars like this as below in SQL.I know that this could be done easily in any other programming language like C,C++,Java but want to know whether it is really possible with just SQL or PL/SQL.I tried working on it with dual table in Oracle but couldn't get through it.

Hi,
I am basically working on unix and c programming.
i want to start learning Pro*c on unix.
Is there any good online tutorial which will help me start writing simple programs in pro*c and compiling those Pro*c files.?
Thanks in advance for your help.
I'm currently investigating what the runtime of different programming languages looks like behind the scenes. For a compiled language like C, people usually give the explanation of "Code is compiled to assembly which is assembled and linked into a binary executable. The executable is then loaded into memory and the CPU interprets it." My question is how does the CPU know where to look for the next instruction to execute? Is it a memory address stored in one of the registers?
I want a simple timeline component (like in video editing software) for a clojure/seesaw app and I am wondering if it is a good approach to implement this directly with clojure and seesaw or if I should write it in java and make my clojure wrapper around it.
Or more generally: is a functional programming language optimal for writing UI widgets? I cannot imagine doing that without a lot of state involved. And wasn't OO invented for UI-development in the first place?
I would like to add a favorites tab to my iphone app that i am developing. I am using core data to populate a UITableView and would like in the detailed view to be able to add the selected item to the users favorites.
Would i go about this by adding the selected item to a new array?
I am very new to xcode and iphone programming so as much help and code would be gratefully received.
I'm currently developing a small Database Management System for a local company. How would you go about explaining how the system you have designed to a client? If they are non-technical and have no understanding of programming, how would you go about showing what the system will do and how it will do it? I guess some sort of visual representation of the system but this seems very patronising to me.

I need to teach myself Winforms and user interface programming and want a decent book that will go thoroughly into the ins and outs of how to accomplish things.
Can anyone suggest a good book?
I know C# pretty well and have messed about with Winforms in the designer before.
Thank you
I have a string (R(46 - 9900)) AND ( NOT (R(48 - 9900))) where R denotes Range . If you evaluate the expression it results in R(46-47) , considering the logical operators (AND,NOT).
I have a requirement where I need to parse such a string and evaluate it to a correct result . I have to use C++ as a programming tool to achieve this result .
Can anyone suggest a few guide lines as to how do I proceed on this ?
I'm rather new with the whole OSX programming, I wanted to stick a WebView into an empty app. Apparently it isn't as simple as sticking a WebView on a window in interface builder and creating an outlet.
IBOutlet WebView *webView;
It gives me a
expected specifier-qualifier-list before 'WebView'
and when I don't use an outlet, it terminates due to uncaught exception. I'm not too sure what these error messages mean.
Seems it isn't that simple!
