Dreamweaver CS4 introduced a number of changes, not the least of which was how they beefed up the Spry tools. Some of my favorite new features are Live View, Live Code View and the introduction of HTML as a data source. I recently led a workshop at TechEd09 on Dreamweaver and Spry. I dusted off chapter 9 (the Spry chapter) from Adobe Dreamweaver CS3 with ASP, ColdFusion, and PHP: Training from the Source to incorporate the changes in CS4. The new chapter and the exercise files can be found on the book’s download page. Enjoy!
