Pocket PC Network Programming is the resource developers need to exploit the power of mobile technology and high-speed wireless connections. This book is a comprehensive tutorial and reference for writing network applications on Pocket PC 2002 and Pocket PC 2002 Phone Edition devices. It explains how the Pocket PC communicates with the Internet, with other mobile devices, and with networks. It teaches developers the basics of Pocket PC telephony, synchronization, and messaging.

Pocket PC Network Programming begins with a guide to writing applications that communicate over the Internet and then explores how to use Pocket PC devices with Windows-based networks, how these devices communicate over serial and infrared, and how they utilize Remote Access Services (RAS). The focus then shifts to the Pocket PC 2002 Phone Edition before turning to the building of applications designed for synchronization with a desktop computer. The final chapters cover the Pocket Outlook Object Model, the Mail API, and the .NET Compact Framework.

Key topic coverage includes:

Understanding the basics of Winsock, Windows Internet (WinINet), the IP Helper APIs, HTTP, and the File Transfer Protocol (FTP) Using network resources

Creating, establishing, and controlling dialup network connections

Integrating applications with the Pocket PC Connection Manager

Short Message Service (SMS) Messaging

Using the Global System for Mobile communication (GSM)

Interacting with the Subscriber Identity Module (SIM)

Remote control of a device from a desktop

Building an ActiveSync Service Provider

Building applications that integrate with Contact, Application, and Task data

Writing e-mail enabled applications

Programming and writing network applications and using Web Services with the .NET Compact Framework

Programming Microsoft Windows CE

Introduction

I was introduced to Microsoft Windows CE right before it was released in the fall of 1996. A Windows programmer for many years, I was intrigued by an operating system that applied the well-known Windows API to a smaller, more power-conserving operating system. The distillation of the API for smaller machines enables tens of thousands of Windows programmers to write applications for an entirely new class of systems. The subtle differences, however, make writing Windows CE code somewhat different from writing for Windows 98 or Windows NT. It's those differences that I'll address in this book.
Just What Is Windows CE?

Windows CE is the newest, smallest, and arguably the most interesting of the Microsoft Windows operating systems. Windows CE was designed from the ground up to be a small, ROM-based operating system with a Win32 subset API. Windows CE extends the Windows API into the markets and machines that can't support the larger footprints of Windows 98 and Windows NT.

Windows 98 is a great operating system for users who need backward compatibility with DOS and Windows 2.x and 3.x programs. While it has shortcomings, Windows 98 succeeds amazingly well at this difficult task. Windows NT, on the other hand, is written for the enterprise. It sacrifices compatibility and size to achieve its high level of reliability and robustness.

Windows CE isn't backward compatible with MS-DOS or Windows. Nor is it an all-powerful operating system designed for enterprise computing. Instead, Windows CE is a lightweight, multithreaded operating system with an optional graphical user interface. Its strength lies in its small size, its Win32 subset API, and its multiplatform support.
Products Based on Windows CE

The first products designed for Windows CE were handheld "organizer" type devices with 480-by-240 or 640-240 screens and chiclets keyboards. These devices, dubbed Handheld PCs, were first introduced at Fall Comdex 96. Fall Comdex 97 saw the release of a dramatically upgraded version of the operating system, Windows CE 2.0,with newer hardware in a familiar form—this time the box came with a 640-by-240-landscape screen and a somewhat larger keyboard.

In January 1998 at the Consumer Electronics Show, Microsoft announced two new platforms, the Palm-size PC and the Auto PC. The Palm-size PC was aimed directly at the pen-based organizer market currently dominated by the Palm Pilot. The Palm-size PC sports a portrait mode, 240-by-320 screen and uses stylus-based input. A number of Palm-size PCs are on the market today.
