Introductory tutorial on Visual Basic error handling Introduction In this article, you’ll learn how to build blocks of code that handle run time errors, also referred as exceptions which occur as a result of normal operating conditions for example. Errors due to a disk not being in the drive or to an offline printer. Visual Basic .NET includes the Try---Catch code block, a new syntax for handling error. In this article you’ll learn how to trap run time errors using Try---Catch code block, and you’ll learn how to use the Err.Number and Err.Description properties to identify specific runtime errors. You’ll also learn ho

From here, you will be able to get on your way to ascertaining full understanding of the language. This chapter is from the book This chapter is from the book Sams Teach Yourself Microsoft Visual Basic .NET 2003 in 21 Days, 2nd Edition Learn More Buy This chapter is from the book This chapter is from the book Sams Teach Yourself Microsoft Visual Basic .NET 2003 in 21 Days, 2nd Edition Learn More Buy Today, we're going to look at some crucial aspects of the Visual Basic language: procedures such as Sub procedures and functions, procedure scope, and exception (runtime error) handling. We'll also get an introduction to a topic that's become central to Visual Basic: classes and objects. Now that our code is growing larger, it's good to know about procedures, which allow us to break up our code into manageable chunks. In fact, in Visual Basic, all executable code must be in procedures. There are two types of procedures: Sub procedures and functions. In Visual Basic, Sub procedures do not return values when they terminate, but functions do. If you declare variables in your new procedures, those variables might not be accessible from outside the procedure, and that fact is new also. The area of your program in which a data item is visible and can be accessed in code is called scope, and we'll try to understand scopea crucial aspect of object-oriented programmingin this chapter. We'll also l
