Inside Delphi 2006 (Wordware Delphi Developers Library)

Overview

The examples we wrote in previous chapters, especially the ones that illustrate how to dynamically create objects, can be considered pretty unsafe. The reason is simple: The examples contain no or very little error-handling code. The only examples that check for errors extensively are the examples that use the IOResult function to see if an I/O error occurred.

This chapter deals with exception handling (also known as structured exception handling) — an error-handling mechanism that enables you to respond to errors in a uniform manner.
