We always used our computer system program to shutdwon, log-off, and restart our pc. But here in vb.net we can also do that.

Now, let's start this tutorial!

1. Let's start with creating a Windows Form Application for this tutorial by following the following steps in Microsoft Visual Studio: Go to File, click New Project, and choose Windows Application.

2. Next, add three buttons named Button1 labeled as "Shutdown", Button2 labeled as "Logoff", and Button3 labeled as "Restart". You must design your layout like this:



3. Now put this code for your code module.

1. Public
   
   Class
   
   Form1
   
2. 
   
3. Private
   
   Sub
   
   Button1_Click(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Button1.
   
   Click
   
4. Shell(
   
   "shutdown -s -t 10 -c computer,will,shutdown,after,10,seconds"
   
   )
   
5. End
   
   Sub
   
6. 
   
7. Private
   
   Sub
   
   Button2_Click(
   
   ByVal
   
   sender As
   
   System.
   
   Object
   
   , ByVal
   
   e As
   
   System.
   
   EventArgs
   
   )
   
   Handles
   
   Button2.
   
   Click
   
8. Shell(
   
   "shutdown -l -t 10 -c computer,will,log-off,after,10,seconds"
   
   )
   
9. End
   
   Sub
   
10. 
    
11. Private
    
    Sub
    
    Button3_Click(
    
    ByVal
    
    sender As
    
    System.
    
    Object
    
    , ByVal
    
    e As
    
    System.
    
    EventArgs
    
    )
    
    Handles
    
    Button3.
    
    Click
    
12. Shell(
    
    "shutdown -r -t 10 -c computer,will,restart,after,10,seconds"
    
    )
    
13. End
    
    Sub
    
14. End
    
    Class
    

Legends/Explanation:

s stands for shutdown
r stands for restart
l stands for log off
t stands for countdown time
a stands for abort/cancel
c stands for message box and word is seperate by comma

The shell method here represents the objects in the Shell. Methods are provided to control the Shell and to execute commands within the Shell.

When you click Button1 it will shutdown your pc after 10 seconds.
When you click Button2 it will logoff your pc after 10 seconds.
When you click Button3 it will restart your pc after 10 seconds.
