  File:      NoticeNumbers.cpp

  Contents:  Implementation of CNoticeNumbers class for collection of 
             IExtension objects.

  Remarks:   This object is not creatable by user directly. It can only be
             created via property/method of other CAPICOM objects.

             The collection container is implemented usign STL::map of 
             STL::pair of BSTR and IExtension..

             See Chapter 9 of "BEGINNING ATL 3 COM Programming" for algorithm
             adopted in here.

  Function : CNoticeNumbers::Init

  Synopsis : Load all extensions into the collection.

  Parameter: DWORD cNoticeNumbers - Number of extensions.
  
             int * rgNoticeNumbers - Array of extensions.

  Remark   : This method is not part of the COM interface (it is a normal C++
             member function). We need it to initialize the object created 
             internally by us.

             Since it is only a normal C++ member function, this function can
             only be called from a C++ class pointer, not an interface pointer.
