How to darken background?

[Behzad]

hi all,

I'am recently working on an applicatoin.Whenever a user creates a new
project in my application the new project's form is displayed.The users
are unfamiliar with computer wolrd.I want to focus their attention on
what is really working on top of the screen ( say it is a new project
form).Now i have decided to darken the background screen and the result
would be something like "Shut Down Windows" form in Windows XP/2003.how
could i do this?

Thanks in advance.

hi ,

try to put a semi-transparent grey form behind your new project form.
this form should cover the whole desktop.
i hope you get the efect that you want!

regards.

this.BackColor = Color.Black;

Hm... Read the question again.

this.BackColor = Color.Black;

Behzad,

It won't be to easy to create such an effect with the provided managed
api. Wouldn't be easier to create a system modal form where the user
cannot change focus ?

The effect you see when shutting down windows XP is achieved by capturing
the whole screen, manipulating the captured picture and showing it "full
screen" while showing a window in front of it. Try to start the clock by
double clicking time in the taskbar and see it stop after you chose shut
down windows from start menu.

This is not very practical when you need to do this in an application,
because there may be other applications needing showing user an input.
Displaying a semitransparent fullscreen grey window in the background would
be most practical, if it is possible to do.
