[RESOLVED] Any dim overlay on a form ideas?

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/.

I came up with this idea

Code:

---

    Private Sub Button3_Click(sender As Object, e As EventArgs) Handles Button3.Click
        While Me.Opacity > 0.5
            Me.Opacity -= 0.00001
        End While
        MsgBox(CStr(Me.Opacity * 100) & "%")
    End Sub

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        While Me.Opacity < 1
            Me.Opacity += 0.00001
        End While
        MsgBox(CStr(Me.Opacity * 100) & "%")
    End Sub

And it works perfectly fine. Liked the way opacity and background melted together.

Em, Hi. Please ignore the last sentence, "perfectly" part. It depends on host computer resources. In some cases it took me few hours to accomplish.

It is a closed thread but can someone please implement it through a parallel thread to avoid visual unresponsiveness?
