To instantiate the iCallLogger, from the observing class, use something like this:
iCallLogger = CmytravelrCallLogAgent::NewL();
Lates Entry Deletion:iCallLogger->ReadRecentEventsL();//read and delete recent dialed number
Then, in the destructor of the instantiating class:delete iCallLogger;
Code:.h File:#include <f32file.h> // RFs
#include <logcli.h> // CLogClient
#include <logview.h> // CLogViewEvent
#include <logwrap.h>
#include <logwrap.hrh>
enum
{
EGetRecent,
EDeleteEvent,
EIdle
};
RFs iFs;
CLogClient* iLogClient;
CLogViewRecent* iLogViewRecent;
TInt iTask; // task for RunL
.cpp File:
CmyCallLogAgent* CmyCallLogAgent::NewL()
{
CmyCallLogAgent* self = CmyCallLogAgent::NewLC();
CleanupStack::Pop(self);
return self;
}
CmyCallLogAgent* CmyCallLogAgent::NewLC()
{
CmyCallLogAgent* self = new (ELeave) CmyCallLogAgent();
CleanupStack::PushL(self);
self->ConstructL();
return self;
}
CmyCallLogAgent::CmyCallLogAgent():CActive(EPriorityStandard)
{
}
// initiation of handles, Log client and recent viewer
void CmyCallLogAgent::ConstructL()
{

// Establish a connection to log engine
iLogClient = CLogClient::NewL(iFs);
iLogViewRecent = CLogViewRecent::NewL(*iLogClient);
iTask = EIdle;
CActiveScheduler::Add(this);
}
//object destruction
CmyCallLogAgent::~CmyCallLogAgent()
{
Cancel();
delete iLogViewRecent;
delete iLogClient;
