IDataObject::EnumDAdvise method (objidl.h)
Creates an object that can be used to enumerate the current advisory connections.
HRESULT EnumDAdvise( [out] IEnumSTATDATA **ppenumAdvise );
A pointer to an IEnumSTATDATA pointer variable that receives the interface pointer to the new enumerator object. If the implementation sets *ppenumAdvise to NULL, there are no connections to advise sinks at this time.
This method returns S_OK if the enumerator object is successfully instantiated or there are no connections. Other possible values include the following.
||Insufficient memory is available for the operation.|
||Advisory notifications are not supported by this object.|
The enumerator object created by this method implements the IEnumSTATDATA interface. IEnumSTATDATA permits the enumeration of the data stored in an array of STATDATA structures. Each of these structures provides information on a single advisory connection, and includes FORMATETC and ADVF information, as well as the pointer to the advise sink and the token representing the connection.CreateDataAdviseHolder, implementing IDataObject::EnumDAdvise becomes a simple matter of delegating the call to IDataAdviseHolder::EnumAdvise. This creates the enumerator and supplies the pointer to the OLE implementation of IEnumSTATDATA. At that point, you can call its methods to enumerate the current advisory connections.
