>Do you really need a complete data session? What about just creating a non-visual data environment class and put it inside of a container? That way everything inside the container would have access to that particular data environment. I'm not sure how easy it would be to create a private datasession using this, though. But would a private datasession really be needed if each class handled everything regarding it's own data?

it's more easy if you really have a datasession because you don't have to take care of what is already open and on wich alias name is used and do i need to save some setting before used it. May be it's because i used a lot of free table (for compatibility) but it was really easier if i can have a complete datasession in some case....

Thank's for your reply
