Demonstrates

One of the keys to a highly mobile smart client is that it be aware of its power status. Because certain graphical, file, and network operations can be battery-intensive, a smart client application should be able to change its behavior to allow for various power situations if possible.

Although power-awareness is not part of the .NET Framework 2.0 class library, you can easily implement it by using P/Invoke. This sample provides some power-aware classes and enumerations and demonstrates how to use them to read the charging status and battery strength of a smart client.

This sample is not specific to Microsoft Windows XP Tablet PC Edition 2005. It does not require the Tablet PC Platform SDK.
