Shut down the computer

  Well you might not have shutdown priviledges.
  
  Or else, try calling the API twice in a row. I've seen it used occasionally.

  Ahhh... the heavenly archives of MSDN
  
  http://msdn2.microsoft.com/en-us/library/aa376868.aspx
  
  In particular, check the shutdown constants, and the remarks section.
  Mostly, the AdjustTokenPriveledge part (also: http://msdn2.microsoft.com/en-us/library/aa375202.aspx)
  
  EDIT: Complete example in C: http://msdn2.microsoft.com/en-us/library/aa376871.aspx
  
  Now note that this code will only work for XP and above.
  If you're also planning on using it for 98 and/or NT/2000 then you'll probably have to get a bit m

  Thanks for the Link but it doen't help me much because it is C.
  I have tried to work it out but there also appears to be calls to functions in a library I haven't included.
  
  I do have microsoft.win32.
  
  Any VB code that does the same job as the C and any required libraries would be helpfull.

  I have a complete .NET control at my website under the Visual Basic.NET - Controls page that will restart, shutdown, logoff, initiate shutdown, and more that is very easy to use. Simply add a reference to the compiled class library and create a instance and your good to go.
  
  You could also use shell code to manipulate the Windows Shutdown Process to shutdown the computer. Example:
  
  Process.Start("shutdown -s -f -t 0") 'Will Shutdown the computer.
  
  Process.Start("shutdown -r -f -t 0") 'Will Reboot the computer.
  
  Process.Start("shutdown -l -f -t 0") 'Will Logoff the user.
  
  
  Hope this helps

  I took a look at the control. Nice code!
  I almost had a working code, but the AdjustTokenPrivelege function kept giving me errors and I had not yet succeeded in fixing it.

  These Codes will work only on XP.

  : Process.Start("shutdown -s -f -t 0") 'Will Shutdown the computer.
  :
  : Process.Start("shutdown -r -f -t 0") 'Will Reboot the computer.
  :
  : Process.Start("shutdown -l -f -t 0") 'Will Log off the user.
  :
  if u used this command, your program will restart or do what ever by sending it to DOS Prompt try this in DOS Mode (Windows)
  shutdown -s -f -t 0
  to understand about is try this on dos prompt.
  shutdown /?
  --------------------------------------------------------------
  if u use
  Shutdown -a
  shutdown or restart process will abort.
  
  the way you are going to restart, is not the best practice.
