Class..Object (ASP Classic and PHP Cross Reference Guide)

By Mike Prestwood

ASP Classic versus PHP: A side by side comparison between ASP Classic and PHP.

OOP Basics

Some languages support object-based concepts such as Paradox, Access, and VB Classic. Other languages have OO extensions and fully support object orientation in a hybrid fashion (such as C++ and Dephi for Win32). Finally, some lanages such as C#, VB.Net, Prism, and Java are entirely written in OO. Meaning, every line of code written must occur within a class).

Class..Object

[Other Languages]

Languages Focus

In short, a class is a data type, and an object is an instance of a class type. A class has methods (routines), properties (member variables), and a constructor. The current values of the properties is the current state of the object. The UML is one of the diagraming disciplines that allows you to document the various changing states of a series of objects.

ASP Classic: Class..Set..New

Ultra-primitive (no inheritance) but useful and encourages you to think and design using objects. Unlike VB, you can have more than one class per file.

Classes in ASP do support member fields, properties, and methods.

Syntax Example:

'Declare class.

Class Cyborg

  Public Function IntroduceYourself()

    Response.Write("Hi, I do not have a name yet.")

  End Function

End Class

'Create object from class.

Set T1 = new Cyborg

T1.IntroduceYourself()

Set T1 = Nothing      'Be sure to clean up!
