“Active objects are a fundamental part of Symbian OS™ and are used to simplify asynchronous programming. They make it easy for programmers to write code to submit asynchronous requests, manage completion events and process results. They are well suited for lightweight event driven programming, except where a real-time, guaranteed response is required.”

Quote from “Symbian OS Explained: Effective C++ Porgramming for Smartphones” by Jo Stichbury, John Wiley and Sons, 2005.

This simple application is meant to be an introduction to the active object framework and implements an active object using an RTimer as a service provider. The application will every 10th second call “HAL::Set(HALData::EBacklightState,1)” which will ensure that the screen will continue to shine. Of course you can use the menu to stop issuing this function call. Bear in mind, to make this application running you will need to have the capability WriteDeviceData set in your mmp file. This will require signing the application.

Basically e.g ppl had problem keeping the back light open ryte? well this is a shortcut to solving dat problem.

People had trouble keeping the back light on while playing coreplayer, divx and powermovie? well u can turn on the backlight before u start watching a movie. No need to go through all that hassle to turn the background light on.
