Groups and Users Append, ChangePassword Methods Example (VB)

This example demonstrates the Append method of Groups, as well as the Append method of Users by adding a new Group and a new User to the system. The new Group is appended to the Groups collection of the new User. Consequently, the new User is added to the Group. Also, the ChangePassword method is used to specify the User password.
