Locking C# Desktop window on Top all windows and prevent user change window : <p>I want to code a c# program that starts with windows and, sometimes, ask what the user is doing. So, I want to open a window to the user fill the form asking what he is doing, but I want to open the window on top of the screen and lock everything else, forcing the user to fill out the form before went back to what he was doing. Is it possible ? </p>

<p>The behavior I want it is just like some modals on webpages that darkens the background forcing you to fill a form, but, instead do this on a webpage, I want to do this on Windows Desktop (Don´t need to darkens the background, just force the user to fill the form). </p>
