This text deals with object-oriented programming and how it is implemented in Microsoft Visual Basic. Accordingly, the book has two separate, though intertwined, goals: to describe the general concepts of object-orientation, and to describe how to do object-oriented programming in Visual Basic. Readers are assumed to have a familiarity with Visual Basic and some rudimentary knowledge of programming. On this foundation, Steve Roman introduces the abstract concepts of object orientation, such as class, abstraction, encapsulation and then shows how each are implemented in a meaningful and useful application. Throughout the style is hands-on: plenty of code is given and discussed, including error-handling.
