Cursor..::.MovePrev Method (DatabaseEntry, DatabaseEntry)
Cursor Class See Also Send Feedback

If the cursor is not yet initialized, MovePrev is identical to MoveLast()()(). Otherwise, move the cursor to the previous key/data pair of the database, and store that pair in Current. In the presence of duplicate key values, the value of Current.Key may not change. 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, MovePrev is successful, and any existing bytes are returned.
