Getting Started With Palm Query Application Development
Published on 2010-06-01 08:57:00
IntroductionA Palm Query Application, or PQA as they are commonly called, is a special type of application for Palm VII devices that allows a user to interact wirelessly with Web content. A PQA takes the concept of interactive Web browsing a step farther by consolidating related, static content into an application that can be installed on a Palm VII device. Links within a PQA document can either refer to other pages within the application or they can refer to documents or scripts residing on a p

Here's what happens when you access a Web site using a WAP-enabled device: You turn on the device and open the minibrowser. The device sends out a radio signal, searching for service. A connection is made with your service provider. You select a Web site that you wish to view. A request is sent to a gateway server using WAP. The gateway server retrieves the information via HTTP from the Web site. The gateway server encodes the HTTP data as WML. The WML-encoded data is sent to your device. You se
Wireless Markup Language

WAP uses Wireless Markup Language (WML), which includes the Handheld Device Markup Language (HDML) developed by Phone.com. WML can also trace its roots to eXtensible Markup Language (XML). A markup language is a way of adding information to your content that tells the device receiving the content what to do with it. The best known markup language is Hypertext Markup Language (HTML). Unlike HTML, WML is considered a meta language. Basically, this means that in addition to providing predefined tag
The Cellular Explosion
