Hi!

The most lightweight object in VFP is "Relation". Session object used because easy to hide tables opened in that data session to do nto make any conflicts.

See also following page that helped to determine the most lightweight object:

HTH.

>Hello All,
>I've always used the line class as a base for my non-visual classes, is this still the lightest base class?, I ask this because I frequently see non-visual classes based on the session class, I am reluctant to use this because of the environment issues ( Sets etc... ), am I wrong not to use it?
