How to make screen become gray/dark slowly?

For a WinForm application using C#, how to make the form become gray/dark slowly when pop up a dialog? Like XP does when user is going to shut down computer. Thanks in advance.

Is it at all required to produce Grayscale using Bitmap when you can do this easily using Opacity of a form ?? :doh:

How can you turn other windows gray by setting opacity of the form?

Just place the transparent form(with black background) over all other window and set opacity to a value less than 50%... maybe it could animate the opacity from 0 to 50.... It will be done automatically... :)

Actually no. Just tested it and you can still see the colors of the underlaying windows. All this does is put a grayish 'film' over it but the colors of any window behind it are still very visible.

Microsoft Bing MAP using JavascriptNo. That wont turn the title bar of the windows behind to gray. Background windows will still be olive green (as per my system settings). You need to use similar mechanism as what XP uses or digg in to Nish's article. Since it is in C++, I don't get much out of it.

You might look this then http://techneighbour.co.cc/blog/2009/09/dialogbox-imitating-windows-shutdown-dialog/[^] Well... But there is lots of Double buffering, Timers, Bitmaps etc. I think this would be a lots of load for this simple task. :laugh: :laugh: . dont you think ? :^) Anyway, I agree background colors will appear as it is for my solution... ;P

Microsoft Bing MAP using JavascriptWell, if you need replica of XP feature, AFAIK you got two ways: 1. Find how windows does that and maybe P/Invoke the dll. 2. Use what is there in the article. If you can settle with ModalPopUp (Ajax) like background, use a Panel and play with its AlphaGradient. Or use a new form as you suggested.
