Protect from editing a group of controls in a dialog

[ssimop]

I am in need to protect from being edited a group of controls in a dialog, in other words to temporarily protect a form from being edited. At present I am doing it using individual EnableWindow(id(...) 0) statements for each one of the fields.

I wonder weather it is possible to define a group and disable the group as a whole. Many thanks in advance for any advice.
