VB Classes

Hi all,
I have 3 questions regarding classes.
1:- If I have a class, Class1, how do I get Class2 to inherit class1?
2:- Assuming that the above is possible, if Class1 contains a function,
Funct1, what scope keyword do I need so that Funct1 is only visible
to derived classes?
3:- Can the same be done with constants and varibles?

Thanks for any input.

An alternative (just for the record, it is not the easiest one, although
it may prevent some code duplication) is using events.

An example:
Say you have a superclass called "DataStorage", which has an abstract
method "StoreString". A subclass "DatabaseStorage" would store the
string in a database.

In VB6, there's a kind of "upside down" form of inheritance with events.
You can create an instance of the DatabaseStorage class and feed it an
instance of the "superclass" DataStorage. This instance is internally
stored with the "Withevents" keyword. If the "StoreString" method of the
"superclass" just raises an event, the "subclass" instance containing
it will handle the storage action.

Best regards
