Hi all o7
The idea is when you are about to terminate using the app, some sort of dark overlay covers all the background and a dialog or maybe a control (latter one would be tricky) appears. Fade in/out effect is not necessary but if it is possible to implement, I would be delighted. A faster version of Win98 shutdown decision making window.

A semi-transparent shape (or a newer blurry fluent shape) is needed. Another low-opacity form would not be OK since the control I'd like to pop up is a 3rd party radialmenu in center of screen.

Entire project is vb.net windows form based (not a WPF fan) but I'm a trial user of devexpress. Did not find any related material there (their forum is not a big deal to be honest or maybe QAs are not visible to public idk).

But if someone find their controls easy to perform such thing, I rather use XtraForm. peace/.
