Chapter 4. Advanced MapPoint 2004 Programming
In the previous chapters, you learned how to use MapPoint 2004 APIs to perform simple location-oriented tasks, business data display, and management tasks. Now it’s time to learn how to integrate and extend MapPoint 2004 APIs, as well as how to improve the performance and memory usage of your MapPoint 2004 applications. You’ll learn how to:
Extend MapPoint 2004 by interfacing with a GPS device
Integrate your applications by writing COM Add-Ins
Improve your MapPoint 2004 application performance
Sample applications used in this chapter are available in the companion material under the Chapter04 directory.
Interfacing MapPoint 2004 with a GPS Device
While MapPoint 2004 makes most of its features available via the APIs, there is one feature that you may wish to use that is not available: the ability to interface with a GPS (Global Positioning System) device. Interfacing with a GPS device is fairly independent of any specifics of MapPoint 2004 implementation. The details of MapPoint 2004 interfacing with a GPS device lie in serial port communication and parsing standard NMEA GPS sentence streams. By interfacing them, you can write applications that use MapPoint 2004 and a GPS device to show location in real time.
The first step in building a location tracker application is to understand how GPS works. While it is beyond the scope of this book to discuss it in detail, I want to provide some basics so that it will be easier for those unfamiliar ...
