Not really. A GETNEXT query can't return a lexicographically earlier object, but apart from that you don't really know what'll be returned. If you did, you could just issue consecutive GET queries asking for the precise objects you want. > Then, why the values are returned to the manager in the form of OID=value ? > Are there any ways I can get only the values instead of OID=VALUE form.

For example if you made a thousand single-OID queries a minute, the cumulative size of the OIDs would probably be under 20kB. On a 56.6kbps modem, that would be under 5% of your available bandwidth. I suggest you check your expected usage against your available bandwidth if that's a concern to you. You could also save some (but not much!) bandwidth by using GETBULK. -Dan ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
