I do not understand what exactly you are trying to achieve.
I think you need to minimize application, when user tried to
close the application.
If I am right then find following code useful for the same.
private bool minimize = true;
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (minimize)
{
e.Cancel = true;
this.WindowState = FormWindowState.Minimized;
}
}
And also set minimize variable true on minimize click event to track
that the application is currently minimized.

Hi,
Thanks for your reply, what i want to achieve is.....i am creating a browser which is secure browser for schools and for individual in this children cant browse unwanted sites, the concept of this browser is no one can browse unwanted sites. So the parents can login and minimize or close but it wont visible to his children so no one can open any other browsers, with out parent knowledge. I will try ur code and update u.
Thanx

You probably want a Windows Service.
P.S. How will you recognize a browser?

Iam recognizing the browser through process. Killing active browser process and its working fine. I need to get disappear after minimize or close the browser window ...but the state should be active till logout as i explain to u.

This is a lousy way to do this since any browser can be renamed to some filename and still work. How many browsers are you up against? Look at this list[^].
You don't close browser windows. The traditional way to do this is to write a proxy server. That way, you can filter out the URL's being accessed without knowing which browser the user is running.
Windows services do not care if anyone is logged in or not. They still do their job if noone is logged in.

I agree ur point, can u give me some idea how to use proxy server to stop other browsers.
Thanx

You're going to have to write a proxy server to do this, or just skip all the work and BUY one off the shelf.
You'll be writing a proxy server that listens for requests from web browsers. The proxy will then go get the web page from the requested URL. You can then examine the contents of the returned page and see if you want to return it to the web browser or not.
If you don't know what a proxy server is, how they work, what the protocols involved and how they work, you're going to find this to be impossible to write.
You should also have a good deal of experience in writing TCP/IP servers.

The user could still kill it from there. A Service is less visible and therefore a somewhat better solution, though still not perfect. Basically, what you are trying to do is impossible on a couple of levels.

Completely agree. It is impossible to hide window application
from user in a way that user cannot kill it.
However, if will consider of this point then user can also
kill service from "Task Manager" but it is true that the
service is less visible than to minimize application on
system tray.

This is not the way to go. Since your app will run AS THE USER at all times, they can easily kill it. A user can kill off any process they launch.
A Windows Service can run as Local System, which only an Admin level user can kill. Also, normal users cannot start/stop services.

Hi, I'm just wondering if there are any rules to follow when displaying messages to users. Are there any particular circumstances in which you should "command" the user to do something rather than "ask" them to do something? For example, say you have a login form. The user must of course provide a username and password. If the user does not provide a password should you say "Provide a password and try again" or "Please specify a password and try again"?
I ask this question because I watched a video on YouTube involving ASP .NET Web Form user input validation techniques. The "instructor" said he did not want to command the user to do something but rather inform them politely that they must do it. But I see in some software (and on various products' packaging, too) a mix of "commands" and "polite requests". Some may say "You must provide search terms before you can continue" and then later on something like "Please fill in the required fields and try again".
I hope this makes sense. Hehe. I'm never great with explanations and creating/using examples. But I try. :-P
Thanks in advance!

As a general rule always be polite and ask.
However this depends on your audience and the subject matter. If you are working on a corporate production system, calling your user an idiot is generally frowned upon, but I have seen game and entertainment systems where this is common.
Do your users have a sense of humour? if so you can be a little more relaxed.

That makes sense to me and that's what I was expecting. I just wanted to make sure. Thanks!

I'm always polite  I ask them to please provide a valid entry, if they don't, tough - they just don't get what they want 
But yes, like Mycroft Holmes mentioned, it's dependent on your audience: would be different for games etc.

I recommend never doing something like this[^].

Maybe you gave poor examples; perhaps the user has decided not to proceed and asking him to "try again" is also somewhat rude. I would prefer to simply make a statement "Login failed".
Let's say you stumble across a login page (maybe it's a members-only  area of a website), consider the options:
0) "Enter your username and password" -- perhaps a bit commanding
1) "Please log in to continue to our members-only area" -- requesting, but maybe I don't want to do that (I don't)
2) "Access to our members-only area requires a current username and password" -- a simple statement, it doesn't tell, it doesn't ask
