Webmaster's Guide to the Wireless Internet part 23. The Webmaster’s Guide to the Wireless Internet provides the Wireless Webmaster with all of the tools necessary to build the next generation Internet. Packed with the essential information they need to design, develop, and secure robust, e-commerce enabled wireless Web sites. This book is written for advanced Webmasters who are experienced with conventional Web site design and are now faced with the challenge of creating sites that fit on the display of a Web enabled phone or PDA | 192 Chapter 5 Wireless Development Kits Figure 5.9 Nokia WAP Toolkit Accessing and Editing Local Files You can use the Nokia WAP Toolkit to create edit and view files stored locally on your computer.

The first thing we need to do is change the title. Let s make the attribute read title Hello instead of the default Card 1. We aren t going to add anything new to the card but we can see where we would have to add elements such as onevent do and timer from the com-ments.We can remove these comments to make our final code cleaner.The default do tag has a type attribute of unknown.We want this to be the default action so let s change this so that it
