explains the fundamentals of using error handlers in Visual Basic. There is a lot more to writing bug proof programs than http://www.vb-helper.com/tut6.htm just using error handlers. This book also explains how to reduce the chances of errors occurring in a program, how to detect errors when they do occur, and how to recover from unexpected errors. Visit the book's Web page to learn more. Chapter 12 Error Handling Fundamentals Sections Use On Error Leave Error Handlers Define Error Constants Keep Error Handlers Separate how to Understand Error Handler Scope Don't Nest Error Handlers Error Handling Slides This chapter explains the family of On Error statements Visual Basic uses to handle errors. It tells how a program installs and removes error handlers, and it explains some of the idiosyncrasies of error handling code. After reading this chapter you will be able to write basic error handlers to protect how to display your programs from the unexpected. Use On Error A Visual Basic program uses the On Error statement to register error handling code. This statement can take one of three forms: On Error GoTo 0 On Error Resume Next On Error GoTo line These forms tell Visual Basic what it should do when the program encounters an error. The three forms are described in the following sections. On Error GoTo 0 On Error GoTo 0 is relatively straightforward. It simply cancels any currently installed error handler assigned by a previous On Error GoTo line or On Error Resume Next. If the program encounters an error after this statement executes, it crashes. On Error Resume Next On Error Resume Next makes the program ignore errors. When it encounters an error, the program continues execution after the statement that caused the error. When a program uses On Error Resume Next, it should check the Err object after every operation that might cause an error. If the value Err.Number is nonzero, the operation caused an error and the program can take special action. The program should check Er
