Provides a standard implementation of a way to hold advisory connections.
CComPtr<IOleAdviseHolder> m_spOleAdviseHolder;
Remarks
Observação
To use this data member within your control class, you must declare it as a data member in your control class. Your control class will not inherit this data member from the base class because it is declared within a union in the base class.
The interface m_spOleAdviseHolder implements the IOleObject::Advise and IOleObject::Unadvise methods to establish and delete advisory connections to the container. The control's container must implement an advise sink by supporting the IAdviseSink interface.
