Shutdown, Restart, or Log Off your computer using VB.Net

At first we have to make a simple form that contains 4 buttons (Text property=Shutdown, Restart, Log Off, and Exit)
simply just like the image below


and I made the name property for these buttons to (name=btnShutdown, btnRestart, btnLogOff, and btnExit) that is to help us using and calling the buttons in the code.

But what about the procedure that will make me do the shutdown process
well we write this in the code for each button:
first we write function that will call the shutdown procedure: System.Diagnostics.Process.Start
Then we call the shutdown procedure: ("shutdown",
after we called it we will have to name the process we want to do:
to make it shutdown: we write after the comma "-s"
and to make it restart we write after the comma "-r"
and to make it logoff we write after the comma "-l"

so the code will be for example:
System.diagnostics.Process.Start("shutdown", "-s")
' Will cause the computer to shutdown

but when you order it to shutdown like this it will give you about 20 sec to shutdown
but there is a way to manage that
System.Diagnostics.Process.Start("shutdown", "-s -t 00")
' The -t will contol the time after -t we write the number of sec (Note: max sec = 99)

Now we make for each one of the buttons its own sub (simply we can do that by double clicking on each button)

The code for the whole program will be as follows


Public Class frmShutdown

    Private Sub btnShutdown_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShutdown.Click
        System.Diagnostics.Process.Start("shutdown", "-s -t 00")
        'This will make the computer Shutdown
    End Sub

    Private Sub btnRestart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRestart.Click
        System.Diagnostics.Process.Start("shutdown", "-r -t 00")
        'This will make the computer Restart
    End Sub

    Private Sub btnLogOff_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLogOff.Click
        System.Diagnostics.Process.Start("shutdown", "-l -t 00")
        'This will make the computer Log Off
    End Sub

    Private Sub btnExit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnExit.Click
        End
        'This will make the program to terminate(end the program)
    End Sub

End Class

(I will upload solution file soon so you can download it)
But this function (System.Diagnostics.Process.Start) isn't just for shuting down your computer it call also calls any program or file you want, for example:
System.Diagnostics.Process.Start("C:\Program Files\Internet Explorer\IEXPLORE.EXE")
' This will call the Internet Explorer

you just have to write the path of the file you want to open between the two quotation marks

The article title says:
Shutdown, Restart,or Log Off your computer using VB.NET(Visual Basic.Net)
You used another programing language.
This article can be applied only on Visual Basic.Net

moheeb patuary replied to Abdul Razzak Fallaha at Wednesday, December 05, 2007 1:56 PM

thanks. is thr any c# code pls.

blazingpretzel 1 replied to moheeb patuary at Wednesday, December 05, 2007 1:56 PM

It appears that your problem is that you are running your code in an ASP.NET web page instead of running it in a Windows application. Procedures such as shutting down a computer or opening programs cannot be executed from there. If you want to create an app, there is probably a C# equivalent to this code.

shri b replied to blazingpretzel 1 at Wednesday, December 05, 2007 1:56 PM

i need to execute that command hiding the command prompt,command is right but i dont want the command prompt.....

sourav kumar replied to Abdul Razzak Fallaha at Wednesday, December 05, 2007 1:56 PM

Hi,
Can you give me an idea or code in c# or vb to access the process of another machines that are connected in LAN or in same work group.

santosh behera replied to Abdul Razzak Fallaha at Wednesday, December 05, 2007 1:56 PM

hi

i am trying with this shut down,restart,logoff but it is not working.
it's throwing error like(The system cannot find the file specified).

please send me solution.

with regards
santosh

Abdul Razzak Fallaha replied to santosh behera at Wednesday, December 05, 2007 1:56 PM

The problem is that it is not finding the file this way so instead of typing the command like this:
System.Diagnostics.Process.Start("shutdown", "-s -t 00")
you have to type it this way:
System.Diagnostics.Process.Start("C:\WINDOWS\system32\shutdown.exe", "-s -t 00")
That's where the file is.
As i said in the end of my article you can type the whole address.

Thank you for your reply, but I am not actually good with these commands.
But the MSDN (the help) that comes with the programing language is very rich.
Try to search for these commands in the MSDN and I assure you will find what you want.

Thank you again for your reply, and I really apologize for not being able to help.

Best Regards Abdul Razzak Fallaha.

what are the codes if you make a system log out and log in?

Abdul Razzak Fallaha replied to john at Wednesday, December 05, 2007 1:56 PM

You only have to replace the -s (shutdown command) to -l (shutdown command)
So it will look like this:
System.diagnostics.Process.Start("shutdown", "-l")

Thumbs up, Sir! Thanks for that very helpful article. I am actually creating a system using vb 2008. I am hoping you could help me more because I will be asking some questions regarding my systems development from time to time. Keep up!

thams replied to Nick at Wednesday, December 05, 2007 1:56 PM

Does it really work? I mean shutdown -h

Eddy Wissels replied to Abdul Razzak Fallaha at Wednesday, December 05, 2007 1:56 PM

I use the code

process = System.Diagnostics.Process.Start("Shutdown", "-l -t 00") in a service.
The class has FullTrust.
No exception is raised. Still, the function is not executed.
The service assembly is build with Local system.
Deep in the process, I see the process is exited. "Access denied"

Where can I dig, to find an solution to this problem.

Thanks,

mmmmmm replied to Abdul Razzak Fallaha at Wednesday, December 05, 2007 1:56 PM

Abdul, you suck!

What a crap piece of code you newbie present.
First, you should know that shutdown.exe does not work in many circunstances, such as all normal computers that does not run poorly configured as admin accounts.
Second, your code dont even check for permissions, so it will have absolutly no feedback about if it worked or not.

What a waste of time, reposting this shit you found somewhere else.

Abdul Razzak Fallaha replied to mmmmmm at Wednesday, December 05, 2007 1:56 PM

Now i don't know who you are, or were you came from, But i know that you need to learn how to talk!
its ok to criticise people but in a more polite way.
i know that my code is not complete, but i just made it like this to make it simple for beginners.
and it works perfectly.

Please learn how to talk, and then come to negotiate!

Thank you mmmmmm for your comment, and have a nice day!
