DevShed.com has a new article today - the latest in their "Inheritance and Polymorphism" series - Part 3.

In the last part of this three-part series of articles, we will find out how to improve the form generator we created in part II by learning about Polymorphism and adding it to the mix.

Once they have that definition out of the way, they give some code to give an example of its implementation. Finish it all up with the complete source code for the form class, and you're all set...
