Set the cursor to refer to the first key/data pair of the database, 
            and store the secondary key along with the corresponding primary
            key/data pair in Current. If the first key has
            duplicate values, the first data item in the set of duplicates is
            stored in Current. If key, or
            pkey, or data is
            partial DatabaseEntry, its 
            PartialLen bytes starting
            PartialOffset bytes from the beginning
            of the retrieved data record are returned as if they comprised the
            entire record. If any or all of the specified bytes do not exist
            in the record, MoveFirst is successful, and any existing bytes are
            returned.
