If unhandled exceptions occurs in your code due to system or application errors then your application will crash and this is certainly not popular among your visitors or your web host. Exceptions (error) can occur even if your code is perfect due to events beyond your control, a problem to connect to a database server could cause exceptions (errors) in your application.

If you expect that there may be exceptions in your code due to system or application errors (eg incorrect input) then you can handle and control these exceptions by encapsulating your code in Try / Catch / Finally blocks. If there is an exception in code inside a TRY block then this exception will be caught by a Catch expression and thus does the user not even need to know that an exception has occurred. You can write code to create a user-friendly message about the error that has occurred in a Catch block.

In a Try structure can you also include a Finally expression if you must be sure that some code always run even if there is an exception in the code within the Try block. Code that is written after Finally in a Try structure will always run before the end of the Try block with End Try has been reached.
