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.
I googled it for you. Registration is the law. A man who fails to register may, if prosecuted and convicted, face a fine of up to $250,000 and/or a prison term of up to five years. Even if not tried, a man who fails to register with Selective Service before turning age 26 may find that some doors are permanently closed. See also Men over the age of eligibility to register.
