Understanding Structured Exception Handling

Abstract

In this chapter you will learn how to handle runtime anomalies in your VB 2010 code through the use of structured exception handling (often cryptically abbreviated as SEH). Not only will you examine the VB 2010 keywords that allow you to handle such matters (Try, Catch, Throw, Finally), you will also come to understand the distinction between application-level and system-level exceptions, as well as the role of the System. Exception base class. This discussion will lead into the topic of building custom exceptions, and, finally, to a quick look at the exception-centric debugging tools of Visual Studio 2010.
