Hi,

When I opened a form, I want the whole background screen to be blurred. I have searched the web but found nothing on this. Any suggestions?

I am working on C# Winform

That goes against the grain of Windows rather. Applications run in windows and should not blur each other out. Are you talking about Aero effect in 7?

Do you mean you want to take a screen-shot of the current background behind your open Form, blur it, and then show that behind the Form ? I agree with the other opinions expressed here that this is not a good thing to do in Windows.

What you could do is to open a full-screen window and apply the DWM glass effect on it, but unfortunately this stopped working in Windows 8.

Other than that, the solution is to do the gaussian blur effect yourself, which is a really CPU- or GPU-intensive task.

I have to ask: Why would you want this annoying effect? It really breaks the user experience of the user's desktop. Always remember that yours is not the only app running on the user's computer!
