COleVariant GetCacheStart( );
throw( CDaoException, CMemoryException );
Return Value
A COleVariant that specifies the bookmark of the first record in the recordset to be cached.
Remarks
Call this member function to obtain the bookmark value of the first record in the recordset to be cached. The Microsoft Jet database engine requests records within the cache range from the cache, and it requests records outside the cache range from the server.
Note Records retrieved from the cache do not reflect changes made concurrently to the source data by other users.
For more information about caching records, see the article DAO External: Improving Performance with External Data Sources in Visual C++ Programmer's Guide. For related information, see the topic "CacheSize, CacheStart Properties" in DAO Help.
