Hi, folks!

I'm working with a VB Project which deals with a MS Access Database.

I'd like to create some users names and passwords, in order to identify each user everytime he/she starts the program and to control his/her access to some parts of the it.

Where should I create these accounts? Access or VB? When the user clicks a button on a form, the button "Delete record", for example, is there a way to check the user's name before VB proceeds the action?

Please, point me the right direction.
Thanks in advance,
Roselene
