Advanced ColdFusion 8: Components, Error Handling and Complex Objects
Once you have mastered ColdFusion's basics, it is time to discover
its more advanced options. We will explore the many methods of reusing
code (including <cfinclude>, custom tags and stored procedures).
Using session variables and cookies, we will create a Password Protected
section of the site to increase security.
We will teach you how to predict and prevent errors so your users
will never see an ugly error page. Using Regular Expressions, we
will perform advanced Form Validation. Although ColdFusion does
allow for quick an easy development, it still is a robust, powerful
language. We will explore programming concepts including loops,
arrays, structures and two methods for writing User-Defined Functions
(UDFs).
