Prevent Derivation

[Other Languages]

Languages Focus

How do you prevent another class from inheriting and/or prevent a class from overriding a member.

VB Classic: Not Supported

VB Classic supports a form of single level inheritance where you, in essence, create an abstract class and then implement it in one or more classes that inherit from the abstract class. However, you cannot have any further descendant classes so "prevent derivation" is implemented by design of this simple inheritance model.
