An exception is a response error handling class to an exceptional circumstance that arises while a program is running, such as an attempt to divide by zero. Exceptions provide a way to transfer control from one part of a program to another. VB.Net exception handling is built upon four keywords: Try, Catch, Finally and Throw. Try: A Try block identifies a block of code for which particular exceptions will be activated. It's followed by one or more Catch blocks. Catch: A program catches an exception with an exception handler at the place in a program where you want to handle the problem. The Catch keyword indicates the catching of an exception. Finally: The Finally block is used to execute a given set of statements, whether an exception is thrown or not thrown. For example, if you open a file, it must be closed whether an exception is raised or not. Throw: A program throws an exception when a problem shows up. This is done using a Throw keyword. Syntax Assuming a block will raise an exception, a method catches an exception using a combination of the Try and Catch keywords. A Try/Catch block is placed around the code that might generate an exception. Code within a Try/Catch block is referred to as protected code,

Design guidelines for exception handling in .NET which will help you to create more robust software Contents Introduction Plan for the worst Check it early Don't trust external data The only reliable devices are: the video, the mouse and keyboard. Writes can fail, too Code Safely Don't throw new Exception() Don't put important exception information on the Message field Put a single catch (Exception ex) per thread Generic Exceptions caught should be published Log Exception.ToString(); never log only Exception.Message! Don't catch (Exception) more than once per thread Don't ever swallow exceptions Cleanup code should be put in finally blocks Use "using" everywhere Don't return special values on error conditions Don't use exceptions to indicate absence of a
