Set the cursor to refer to key, and store the
primary key/data pair associated with the given secondary key in
Current. In the presence of duplicate key 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, Move is successful, and any existing bytes are
returned.

Parameters
- key
- Type: BerkeleyDB..::.DatabaseEntry
The key at which to position the cursor
- pkey
- Type: BerkeleyDB..::.DatabaseEntry
The key of the current matching record in primary db
- data
- Type: BerkeleyDB..::.DatabaseEntry
The data of the current matching record in primary db
- exact
- Type: System..::.Boolean
If false and in a database configured for sorted duplicates, position the cursor at the smallest key greater than or equal to the specified key, permitting partial key matches and range searches. Otherwise, require the given key to match the key in the database exactly.
Return Value
True if the cursor was positioned successfully, false otherwise.Remarks
If positioning the cursor fails, Current will contain
an empty KeyValuePair<(Of <(TKey, TValue>)>).
