The Pocket PC is the fastest growing platform for building handheld-based enterprise applications. Free from the memory limitations and underpowered processors of other handheld platforms, Pocket Access and eMbedded Visual Basic are providing the Pocket PC with the same one-two punch that Microsoft Access and Visual Basic gave Windows application development in the early 1990s. As the first rapid application development tool for the Pocket PC, eMbedded Visual Basic increases developer productivity and allows for the creation of a wide range of database applications to empower an increasingly mobile workforce.

This is the first book on the market to focus on Pocket PC development using Microsoft's free eMbedded Visual Basic 3.0. "Pocket PC Database Development with eMbedded Visual Basic" is designed to get software developers up to speed building Pocket Access database applications using eMbedded Visual Basic on the Pocket PC. Author Rob Tiffany has put his own Visual Basic background to work in developing advanced Pocket PC applications for large energy companies. It's from this perspective that he guides professional Visual Basic and Access programmers into the world of Pocket PC software development.

This book ramps up your skills in fast-paced but pragmatic fashion. After describing the subset of the SQL language that Pocket PC developers need to know, the author guides you through Microsoft's ADOCE and ActiveSync technologies with no-nonsense examples. Tiffany effectively shares his "been there, done that" experience to help programmers avoid the shoals can sink efforts to build Pocket PC applications that communicate with either local Pocket Access databases or remote SQL Server databases.

The main links with your PC and the outside world are the centronic port, used for connecting the printer, the RS232 port, used for the mouse, and the games port for a joystick. This book explores how these input/output (I/O) ports can be put to use through a range of other interfacing applications. This is especially useful for laptop and palmtop PCs which cannot be fitted with internal I/O cards. A novel approach is taken by this book, combining the hardware through which the ports can be explored, and the software programming needed to carry out a range of experiments.
Circuits are provided for simple testing tools, and three experimental boards - which can also be purchased ready-made. Ready-to-run TurboPascal programs are available on the Newnes web site.
A huge range of applications are considered, turning the PC into a flexible core of a variety of systems. External devices considered include opto-isolator drivers, power drivers, LED drivers, relay drivers, special driver ICs, and methods of driving opto-isolated zero-crossing solid state relays, stepper motors, sound generating devices and displays. Ways of gathering information from the outside world are given, as well as connection to digital devices, remote control and digital communication.
As well as teaching in this field, Pei An has written numerous articles for magazines such as Electronics World and Electronics Today International.
