I have a form in VB.net
when i click the button, a hidden groupbox in the middle of the screen turns visible (with a new menu inside, sort of like a popup.
I need to dim everything in the background out and make it a few shades darker.
i was thinking I make a giant black opaque picturebox in the background
cannot find how to do this
I found some things but don't know how to put them together
Thanks in advance
