set form opacity by clicking a button from it

Feb 6 2009 9:01 AM
Hi
In my aplication I have a form with some buttons that make some comparings
When I click one of those buttons I want the form opacity to be 70%, to "show" that is comparing in this time.
I've seen the msdn example,but that works for a new form. But how can I treat this inside the form, in the buttonClick event
Thanks
