Just a general question about sub classing

This might seem stupid, but what is sub classing and what is it used for?

Use the search feature of this board to search for subclass, you can also search at http://www.codeguru.com/vb
This question is asked at least once a week so it shouldn't be that hard to find a previous given answer.
Or maybe one of the ppl who asked before can anser now to see if you understood *L*

Thanks, I have found what I was looking for!

Thankfull
