Disable

I have created some software, which can be run in Unregistered or registered mode in vb. When the user runs the software in registered mode they type a password which allows them to run it for thirty days after that date if a new password is not entered it goes back to Unregistered mode now when it goes back to this mode I would like it to automatically disable some parts of the program so that they can not be accessed until it registered then once it in this mode the software will open the access to the disable area automatically and them run the same for thirty days and if no new code is entered it does the same thing. ## Deliverables Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. ## Deadline information ASAP
