Cursor Class See Also Send Feedback

Store the key/data pair to which the cursor refers 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, Refresh is successful, and any existing bytes are returned.
