Active Directory

Question

Hey everyone,
     I'm working on a project to set up a new user in AD using VB.  I
have the connection working and I'm able to get most of the settings
done.  However I can't find the properties to set the password to
never expire and the user cannot change password.  I'd also like to
be
able to set the logon hours as well.  If someone can help me out with
those properties in VB I would appreciate it.  Thanks a lot!
