This will disable every control on the form. However, the controls in the groupboxes arent actually disabled from this, they are disabled from the groupbox being disabled. Therefore you could use the code above to disable all controls on the form and then just immediately use.
The Selective Service System wants you to know that the requirement to register for the draft did not go away with the end of the Vietnam War. Under the law, virtually all male U.S. citizens, and male aliens living in the U.S., who are ages 18 through 25, are required to register with Selective Service.
If, after 90 days you still haven't received a registration acknowledgment, call Selective Service at 1-847-688-6888 and use the automated system to check to see if you're in our system. If you've already registered and you're in the system, please disregard all other reminders to register.
