CSimpleSplashScreen.cpp shows very simple implementation of a splash screen. In it the splash screen image is thought to be stored in a image file called splash.mbm (that is in epoc multi bitmap format) and as its first bitmap image. For real implementations replace the <My SID> with your applications secure identifier and store the image in your private folder.

To use CSimpleSplashScreen, just construct it in your application user interface class and start a timer, and when the timer expires, just destroy the splash screen and start your application normal start screen.
