VB6 and Access 97

Hi,
I am developing an application in VB6 accessing an Access 97 database. Now I am going to start developing the security part of the application and I have several questions:

1- Can I use access security from VB6: Adding new users, deleting, etc. Also new user groups. In other words can I control the security from VB6 the same way that I do it from access.

2- Also I am going to need to count the number of users that are accessing the database every time a new user tries to sign on in the application. I am trying to limit the maximum number of user to 5. (I am using dataenviroment in case you need to know).

I really hope some body can help me,

Thanks in advance…
