内容説明
This is a practical tutorial to writing Visual Basic (VB6 and VB.NET) programs using some of the most common design patterns. This book also provides a convenient way for VB6 programmers to migrate to VB.NET and use its more powerful object-oriented features. Organized as a series of short chapters that each describe a design pattern, Visual Basic Design Patterns provides one or more complete working visual examples of programs using that pattern, along with UML diagrams illustrating how the classes interact. Each example is a visual program that students can run and study on the companion CD making the pattern as concrete as possible.
