You can get notifocations for profile activations and handle them inside your applications.

In Header File

#include <settinginfo.h>	// CSettingInfo
#include <settinginfoids.h>	// CSettingInfo ID's
 
//Implement MSettingInfoObserver interface
 
class MyClass:public MSettingInfoObserver 
{
/*
 * Notification handler method
 *
 * param aID			is the ID of changed setting
 *
 * param aNewValue		is the new value of the changed setting
 * given as text, and to be (possibly) 
 *converted into an integer when needed 
 */
		
void HandleNotificationL( SettingInfo::TSettingID aID,
const TDesC& aNewValue );
 
private:

In the CPP File

CMyClass::ConstructL()

	// non observalbe properties (all except the profile
	// index) are read using this instance
