VB Classes

[Geoff Turner]

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.

Re: VB Classes

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 "DataStorag e", which has an abstract
method "StoreStrin g". A subclass "DatabaseStorag e" 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 "StoreStrin g" method of the
"superclass " just raises an event, the "subclass" instance containing
it will handle the storage action.

Best regards
