Object-Oriented Programming in Visual Basic

Current Version: 4.0

.NET is a revolutionary advance in programming technology that greatly simplifies application development. Microsoft’s popular Visual Basic programming language has been upgraded to take advantage of the new .NET features. Visual Basic has become a fully object-oriented programming language with capabilities comparable to C++, Java, and Microsoft’s new language C#.

This course is a practical introduction to programming in Visual Basic and the use of services provided by .NET. It emphasizes the Visual Basic language and how to build Visual Basic applications from an object-oriented perspective. Knowledge of the earlier version of the language, Visual Basic 6, is not required. It is current to Visual Studio 2010 and .NET 4.0, which continues the introduction of new features in the language, making Visual Basic increasingly parallel to C#.

One of the strengths of Visual Basic, and the reason it has enjoyed such widespread use, is the ease with which Windows application can be developed. Microsoft has revamped the way that Windows applications are built under .NET. Windows Forms, used by .NET languages, represents a class library that brings uniformity to the components of a Windows application. The course includes substantial coverage of using Windows Forms in Visual Basic, including creating database applications with ADO.NET.

The first part of the course covers the fundamentals of Microsoft’s Visual Basic programming language. It starts with a brief chapter, “.NET: What You Need To Know,” which gets you up and running in the .NET environment with a minimum of fuss. The next five chapters cover the Visual Basic language essentials.

The second part of the course discusses object-oriented programming in Visual Basic. It contains three chapters that focus on developing classes using Visual Basic and then extending them via Visual Basic’s inheritance capabilities. Interface-based programming and collection classes are also introduced.

The final part of the course introduces Windows Forms. Programmers familiar with previous versions of VB will notice that this significantly changes the programming model, yet also introduces flexibility not previously available. The chapters in this part evolve from building simple form-based applications to ones with dialogs and menus. It includes an introduction to database programming using ADO.NET. The course concludes with a chapter covering the newer features in Visual Basic. An appendix provides a tutorial on Visual Studio 2010.

The course is practical, with many example programs and a progressively developed case study. The student will receive a comprehensive set of materials, including course notes and all the programming examples.

  • The student should have some programming experience.
