Auto Select Internet Access Point (SymbianUIQ)

Auto select internet access point programmatically.We use RGenericAgent and CActive to form an engine based on observer pattern which is most used in symbian app development The following is extracted from my project Notes:.. It is rather simplified and only tested on UIQ platform. Use it at your hrh # ifndef __ipaEngine_hrh # Define __ipaEngine_hrh
