Course Competencies
  1. Create a Visual Basic Windows-based application using object-oriented programming concepts
    Assessment Strategies
    through written examination
    by completing lab exercises
    by writing an application meeting specifications
    Criteria
    your project
    Define what inheritance is and how it promotes software reusability
    Understand the notions of base classes and derived classes
    Use keyword Inherits to create a class that inherits attributes and behaviors from another class
