4202.  Visual Basic Essentials

Rev. 4.0


Microsoft .NET is an advance in programming technology that greatly simplifies application development, both for traditional, proprietary applications and for the emerging paradigm of Web-based services. .NET is a complete restructuring of Microsoft’s entire system infrastructure and represents a major learning challenge for programmers developing applications on Microsoft platforms.


This two-day intensive course is designed for the experienced programmer to help you quickly come up to speed on the Visual Basic language. 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#.


This course concisely covers the essentials of .NET programming using 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 two chapters cover Visual Basic language essentials and object-oriented programming in Visual Basic. The next chapter discusses how Visual Basic relates to the .NET Framework. The following chapter covers delegates and events. The course includes a succinct introduction to creating GUI programs using Windows Forms. The course concludes with a chapter covering 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 goal is to quickly bring you up to speed in writing Visual Basic programs. The student will receive a comprehensive set of materials, including course notes and all the programming examples.




·         Acquire a working knowledge of Visual Basic programming

·         Learn about important interactions between Visual Basic and the .NET Framework

·         Learn how to implement simple GUI programs using Windows Forms

·         Gain a working knowledge of auto-implemented properties, local type inference, object initializers, anonymous types, extension methods, collection initializers, LINQ, and other newer features in Visual Basic


Duration:  2 days. The course could also be presented over a 3-day timeframe for somewhat less experienced students.


Prerequisites:  The student should be an experienced application developer or architect. Some background in object-oriented programming would be helpful.
