Thanks wizard_hu_ it works...
I have used central repository (CRepository) and queried required by using Data Connection Log Counters API.
This how i did which may useful for others also,
Code:
CRepository* iRepository = CRepository::NewL(KCRUidDCLLogs);
GPRSSentCounter:
TBuf<50> bytes;
User::LeaveIfError(iRepository->Get(KLogsGPRSSentCounter, bytes));
GPRSReceivedCounter:
TBuf<50> bytes;
User::LeaveIfError(iRepository->Get(KLogsGPRSReceivedCounter, bytes));
WLANSentCounter:
TBuf<50> bytes;
User::LeaveIfError(iRepository->Get(KLogsWLANSentCounter, bytes));
WLANReceivedCounter:
TBuf<50> bytes;
User::LeaveIfError(iRepository->Get(KLogsWLANReceivedCounter, bytes));
Thanks a lot for the valuable information..
