//===========================================================================
// Summary:
//     This class is the implementation of the XTPCalendarData abstract
//     class which represents the data portion of the Calendar control.
// Remarks:
//     This implementation uses Extended MAPI as the data source.
//     The Data source stores all Events data and provides a way to retrieve
//     and save CXTPCalendarEvent objects.
//
//     To use CXTPCalendarMAPIDataProvider first construct an instance
//     of CXTPCalendarMAPIDataProvider object then use Open() member function
//     to establish connection to the data source and initialize the object.
//     Class provides a number of functions to manipulate events and events
//     related data. After finished working with the data source must call
//     the Close() member function to close the connection and to de-initialize
//     the object and free any unused resources.
//
//     MAPI data provider automatically opens default message store and default
//     user's calendar folder and reads all appointments there. MAPI data provider
//     uses Memory Data Provider internally as a private cache.
//     Also it uses a MAPI notifications mechanism in order to have MAPI
//     appointments always updated. When event is updated in MAPI storage,
//     it will be automatically reloaded in the data provider and updated on
//     the screen. It also works in the same way reverse: when an event is
//     updated in the Calendar control, it will be automatically updated in
//     the MAPI storage.
