A guide to developing applications for the main types of modern mobile devices--the Palm OS and the Pocket PC, this book focuses on using the new MobileVB tool from AppForge to create PDA applications. The applications developed are specifically for Palm devices, pocket computers with the Pocket PC/Windows CE operating system, and for Kyocera and similar communicators. Descriptions are of a different, free development environment from Microsoft--eMbedded Visual Basic 3.0--that allows programmers to create applications for pocket computers with the Pocket PC OS and its previous version, Windows CE. Tasks that use databases including a compact version of the SQL server are emphasized. Described are the basic features of MobileVB and eVB and their limitations when compared to standard Visual Basic. A detailed description is given of the controls (ingots) of each of the languages, the library functions, and the accompanying utilities. Also covered are a wide range of possible programs including games, applications that use databases, and Internet technologies.

Explains how to design and code great applications for Palm-compatible devices using VB, one of the world's most popular programming languages

This text describes how to create a programme that addresses the specific needs and capabilities of middle school students, while helping them through the transition from childhood to young adulthood. This edition is fully updated and revised.

Professional Palm OS Programming is everything programmers need to create applications for the world’s most popular operating system for handheld devices. Veteran Palm developer Lonnon Foster, who has been developing commercial applications for the platform since its introduction nearly a decade ago, provides readers with hands-on instruction, lots of code, and advice that only comes from the trenches – giving readers everything they need to build cutting edge applications and take advantage of the features of both Garnet and Cobalt. Coverage includes: Building forms, menus and user interfaces Managing memory Tying into Palm’s standard applications such as the Calendar, Phonebook, or Tasks Storing program data on removable storage cards Building network enabled applications Creating web applications for Palm Working with Palm OS new support for Web Services Programm ing for new device features such as jog dials, rocker switches, 5-way navigators Working with sounds, graphics, multimedia, and new high-resolution color screens Encrypting and decrypting data Wi-Fi, Bluetooth and wireless networking and more…

With more than 16 million PDAs shipped to date, Palm has defined the market for handhelds, having dominated this class of computing devices ever since it began to outpace competitors six years ago. The company's strength is the Palm OS, and developers loyal to this powerful and versatile operating system have created more than 10,000 applications for it. Devices from Handspring, Sony, Symbol, HandEra, Kyocera, and Samsung now use Palm OS, and the number of registered Palm Developers has jumped to 130,000. If you know C or C++, and want to join those who are satisfying the demand for wireless applications, then Palm OS Programming: The Developer's Guide, Second Edition is the book for you. With expanded coverage of the Palm OS--up to and including the latest version, 4.0--this new edition shows intermediate to experienced C programmers how to build a Palm application from the ground up. There is even useful information for beginners. Everything you need to write a Palm OS application is here, from user interface design, to coding a handheld application, to writing an associated desktop conduit. All the major development environments are discussed, including commercial products such as Metroworks CodeWarrior, Java-based environments such as Sun KVM and IBM VisualAge Micro Edition, and the Free Software Foundation's PRC-Tools or GCC. The focus, however, is C programming with CodeWarrior and PRC-Tools. New additions to the second edition include: A tutorial that takes a C programmer through the installation of necessary tools and the creation of a small handheld application. A new chapter on memory, with a comprehensive discussion of the Memory Manager APIs. Greatly expanded discussions of forms, forms objects, and new APIs for the Palm OS. Updated chapters on conduits that reflect the newer Conduit Development Kit. The best-selling first edition of this book is still considered the definitive guide for serious Palm programmers; it's used as the basis of Palm's own developer training materials. Our expanded second edition promises to set the standard for the next generation of Palm developers.

Originally developed for mainframes but highly portable across platforms-from servers to desktops to handhelds-Rexx is an easy yet powerful scripting language that's widely used for rapid application development. Covers Rexx interpreters for specialized functions-object-oriented, mainframe, and handheld. There are 8 different free Rexx interpreters optimized for different platforms and uses. This book shows how to use them all. Shows how to script for GUIs, databases, web servers, XML, and other interfaces. Details how to make the best use of Rexx tools and interfaces, with examples for both Linux and Windows. Includes a tutorial with lots of examples to help people get up and running.
