This code sample is named GPS. It demonstrates how to use managed code to write a C# Windows Mobile Global Positioning System (GPS) application. This code sample demonstrates how to wrap the native GPS APIs in a C# class. It demonstrates how to use "Platform Invoking" ( PInvoke ) to make calls to unmanaged APIs (in this case, CreateProcess).

Feature Area

Relevant APIs

Usage

To run the code sample

  1. Navigate to the solution file (*.sln), and double-click it. By default, the solution files are copied to the following folders:

    C:\Program Files\Windows Mobile 6.5.3 DTK\Samples\PocketPC\CS\GPS

    Microsoft Visual Studio launches and loads the solution.

  2. Build the solution (Ctrl+Shift+B).

  3. Deploy the solution (F5).

Remarks

The mobile device supports GPS hardware, and make sure that the GPS hardware is setup correctly using the GPS Control Panelin Settings.

Classes

Gps

The interface to the managed GPS API. Use this class to open, close, and query the device state, and to query the position data from your GPS hardware.

GpsPosition

Contains the GPS position data received from the GPS hardware.

GpsDevice

Contains the GPS device state data received from the GPS hardware.

Utils

Native memory allocation utilities.

Development Environments

SDK:Windows Mobile Professional SDK and Windows Mobile Standard SDK

Development Environment:Visual Studio 2005 or 2008.

ActiveSync:Version 4.5.
