CComPtr<IDataAdviseHolder> m_spDataAdviseHolder;
Remarks
Provides a standard means to hold advisory connections between data objects and advise sinks. (A data object is a control that can transfer data and that implements IDataObject, whose methods specify the format and transfer medium of the data.)
The interface m_spDataAdviseHolder implements the IDataObject::DAdvise and IDataObject::DUnadvise methods to establish and delete advisory connections to the container. The control's container must implement an advise sink by supporting the IAdviseSink interface.
