If the cursor is not yet initialized, MoveNextUnique is identical to
MoveFirst()()(). Otherwise, move the cursor to the next
non-duplicate key in the database, and store the secondary key and
primary key/data pair in Current. MoveNextUnique will
return false if no non-duplicate key/data pairs exist after the
cursor position in the database.

Parameters
- info
- Type: BerkeleyDB..::.LockingInfo
The locking behavior to use.
Return Value
True if the cursor was positioned successfully, false otherwise.Remarks
If the database is a Queue or Recno database, MoveNextUnique will ignore any keys that exist but were never explicitly created by the application, or those that were created and later deleted.
If positioning the cursor fails, Current will contain an empty KeyValuePair<(Of <(TKey, TValue>)>).
