title: How to disable all controls on the form except for a button?
body: <p>My form has hundreds of controls: menus, panels, splitters, labels, text boxes, you name it.</p>
  
  <p>Is there a way to disable every control except for a single button?</p>
  
  <p>The reason why the button is significant is because I can't use a method that disables the window or something because one control still needs to be usable.</p>
