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.
The Selective Service, but not the draft, was reinstated in 1980 to show American resolve after the 1979 Soviet invasion of Afghanistan. Today, every man between the ages of 18 and 25 must register with the Selective Service. Young men who don't register are denied federal loans and are barred in most states from entering state universities. Failure to register for the nonexistent draft is a felony that can destroy careers.
