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 requirement to register with Selective Service was reinstated in 1980 but only for men born January 1, 1960, or later. To obtain a copy of a WWII though Vietnam era (men born April 28, 1877 to March 28, 1957), Selective Service Record, please mail a Selective Service Request Form to: National Archives & Records Administration.
