Structured Exception Handling Overview for Visual Basic Visual Studio 2010 Other Versions Visual Studio 2008 Visual Studio 2005 Visual Studio .NET 2003 Visual Basic supports structured exception handling, which you can use to create and maintain programs with robust, comprehensive error handlers. Structured exception handling is code designed to detect and respond to errors during execution by combining a control structure (similar to Select Case or While) with exceptions, protected blocks of code, and filters.Using the Try...Catch...Finally statement, you can protect blocks of code that have the potential to raise errors. You can nest exception handlers, and the variables declared in each block will have local scope. For a related video demonstration, see How Do I: Email Unhandled Exceptions?. The Try...Catch...Finally StatementThe following code shows the structure of a Try...Catch...Finally statement. VB Copy Try ' Starts a structured exception handler. ' Place executable statements that may generate ' an exception in this block. Catch '[optional filters] ' This code runs if the s

An exception is a response 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 handling in visual 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, and the syntax for using Try/Catch looks like the following: Try [ tryStatements ] [ Exit Try ] [ Catch [ exception [ As type ] ] [ When expression ] [ catchStatements ] [ Exit Try ] ] [ Catch ... ] [ Finally [ finallyStatements ] ] End Try You can list down multip
