Developers can now take their RIA concepts out of the browser and onto the desktop. There are so many concepts feasible in an AIR application and with the ability to store data in a local database, programs we have long been familiar with can now be rebuilt with your own added flair. This tutorial will show you how to build a simplified version of Apple???s Address Book using SQLite to store contact information. The UI will be created using MXML components with ActionScript classes to control all functionality. We urposely aimed to use a variety of techniques in the code to handle states, communicate data, etc, so we would recommend studying the source for further insight. To complete this tutorial, you will need to use the source files to access all of the code; certain scripts are covered in each step. In addition, the guide is split over two parts with next month???s final text including the PDF pages and final files from here.
