How to use abstract variables?

[shareconcepts]

Hi,
The concept of Abstract classes is bit clearer but What is the implementation of Variables of Abstract type? Why, when & how the abstract variables are used in a program.

If anyone has idea, plz share it..
Regards.

Abstract classes & members:

http://www.startvbdotnet.com/oop/abstract.aspx

and another one explained slightly differently:

http://www.developerfusion.co.uk/show/4341/9/

the thing is that to use an abstract class, you must inherit from it. (create a new class that inherits from it)
to use its abstract members you must override them.


How do you declare a class to be an abstract class? MustInherit

How do you declare a member to be an abstract member? MustOverride


Hope it clarifies the concept somehow
