|
|
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.
