Introduction - If you have any usage issues, please Google them yourself
Often, we want to disable a set of controls in our dialog. A group box is a good control to categorise a few controls together, but unfortunately it cannot enable/disable its controls. I extended the CButton class and made it very simple to accomplish and it is encapsulated into one class.
So, you can change the title of a group box into a check box or radio button (then you need more group boxes, of course). I must confess I borrowed some ideas of other talented programmers.
