inheritance

[Terry]

"You would only need to inherit one time for a given
class in order for properties and methods to be made
available to your class."

"You would only need to import one time for a given class
in order for properties and methods to be made available
to your class."

"You would only need to dimension one time for a given
class in order for properties and methods to be made
available to your class."

Each seems to be a different way of doing the same
thing.

The visual difference is that imports take place at the
top of a vb document, inherit takes place at the top of a
class, and dimension takes place inside a class. It
seems like there would be SOME reason why there are three
different ways of doing the same thing.

Can someone let me know what is the difference between
the three actions?
