OOP interview question

noreply@blogger.com (タオ　チューン) — Sun, 21 Aug 2011 05:18:00 +0000

What is polymorphism?

Answer: Generally, the ability to appear in many forms. In object-oriented programming, polymorphism refers to a programming language's ability to process objects differently depending on their data type or class. More specifically, it is the ability to redefine methods for derived classes. For example, given a base class shape, polymorphism enables the programmer to define different area methods for any number of derived classes, such as circles, rectangles and triangles. No matter what shape an object is, applying the area method to it will return the correct results. Polymorphism is considered to be a requirement of any true object-oriented programming language.

pligg_validate does not return correct value

noreply@blogger.com (タオ　チューン) — Tue, 06 Apr 2010 08:25:00 +0000

Pligg version 1.0.3

Before
function pligg_validate(){
 // returns the value for register validation
 return misc_validate;  
}

After
function pligg_validate(){
 // returns the value for register validation
 global $db;
 $sql = "SELECT `var_value` FROM `" . table_config . "` WHERE `var_name` = '" . $db->escape('misc_validate') . "';";
 $misc_validate = $db->get_var($sql);
 return return trim($misc_validate)=="true"?true:false;  
}

Wrong Referrer with Pligg

noreply@blogger.com (タオ　チューン) — Fri, 02 Apr 2010 04:18:00 +0000

To debug the problem, edit /libs/html1.php, find the function check_referrer().
To fix this issue, replace $my_base_url value to 'http://localhost' as the following code.

$my_base_url = 'http://localhost';
$my_pligg_base = '';
$dblang = 'en';
define('table_prefix', 'pligg_');
$language = 'english';
include_once mnminclude.'settings_from_db.php';

Version control for Flex Builder

noreply@blogger.com (タオ　チューン) — Sun, 19 Jul 2009 02:20:00 +0000

1. Use Visual SourceSafe:
If you're familiar with Microsoft Visual SourceSafe, it's a bit difficult to apply it in your Flex project. But I think you can use it. Just create a Source Safe project to contain all files in your Flex project. After that, check-out the file you want to work and use Flex Builder to edit.
Steps:
- Install Microsoft Visual SourceSafe to create your project
- Add all of your project's folder and files into this project

2. Use Subversion:
Method 1:
- Install VisualSVN Server to create project repository URL
- Install Subclipse
- Create Flex project as SVN in File/New/Other... with the repository URL has been created.
- Working with version control inside Flex

Method 2:
- Install VisualSVN Server to create project repository URL
- Install TortoiseSVN
- Add the folder contains your Flex project into your project repository URL
- Working with version control outside Flex

3. Use CVS:
I'm not using it frequently, so I'll update it later.
