Set the cursor to refer to the first key/data pair of the database,
and store that pair in Current. If the first key has
duplicate values, the first data item in the set of duplicates is
stored in Current. If either the key or the 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.
