19.0 Control elements

Chapter 19 introduces you to selected components. First, the Settings class is presented, which you use to create and manage configuration files for your application. You can administer application profiles with a profile manager.

You can use the component gb.eval and the function Eval() of the same name to evaluate Gambas expressions at runtime.

Regular expressions are always a challenge, but you can successfully confront them with the methods of the class Regexp (gb.pcre) if you have developed and tested a regular expression adapted to the task. For example, this allows you to check email addresses or German postcodes quickly and reliably.

The gb.logging component implements a flexible system for logging Gambas applications. This component makes its functionality available via the two classes Formatter and Logger.
