AddressbookManager* pAddressbookManager = AddressbookManager::GetInstance();
    IList *pContactList = pAddressbookManager->GetAllContactsN();
    String displayName;
    Contact* pContact = null;
    IEnumerator* pEnum = pContactList->GetEnumeratorN();
    while (pEnum->MoveNext() == E_SUCCESS)
    {
       pContact = static_cast< Contact* >(pEnum->GetCurrent());
       pContact->GetValue(CONTACT_PROPERTY_ID_DISPLAY_NAME, displayName);
       AppLog(“name of contact is %s”,displayName.GetPointer());
