How To List Users In Table

Hi all,

Can anyone help me how to identify who currently has the database open?

For example i have table1 and field1, how can i see in field 1 who is currently in the database as per thier environ("username")

Many thanks and appreciate anyhelp

Wouldnt it be easier to use a sharable db? (spit db on the network)
Then nobody gets locked out.

Thanks for the reply

The db is already on a shared drive. I just wanted to see who is currently in the db for admin purposes
