"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Scripting hooks are typically a feature that is added to a utility or application that allows you to take action or enhance the capability without modifying the original programs.  Under certain conditions of the application they will allow a script to be executed that you can creat, which can do something special and unique that you need.  For example, perhaps when an employee is added in an application, you want to also send an email to that person welcoming them, but the core application doesn't allow that.  If it had a scripting hook on the case of adding an employee, the. You could write a script to send the email, and hook it in.

This allows extensibility and custom actions to be performed which increases the flexibility and usefulness of the application. Sometimes a proprietary scripting language will need to be used, in other case the application will adopt an existing scripting language live vbscript for these extensions.

Hope this helps some,
