DataMemberbstrDM);

[in]
Name of the data member that has changed. This string is interpreted as case-insensitive.

Return Codes

S_OK

E_FAIL

Comments

The data consumer should release its hold on any data access interfaces for that member (such as IRowset or IRowPosition), and should call IDataSource::GetDataMember in order to get the new data (if available).
