  it should see it. Tried specifying shutdown.exe at least its working now ;-) you should also use Process class instead of Shell for many reasons, since its a .NET Class (Process) and is the better way of doing things than using the old VB legacy objects

  That's what is probably is, .net won'd detect it unless you use .net statements.  Even is you use shutdown.exe it doesn't find the file.

  there isnt a class that does this in the .NET Framework but using the shutdown command will work, if your OS supports the shutdown command (Windows 2000, Windows Server 2003, XP and Vista). The correct way of doing so if you have the above:

   

  Dim thePSI as new System.Diagnostics.ProcessStartInfo("shutdown.exe")

  thePSI.Arguments = "/m \\computerName /s /t 10"

  System.Diagnostics.Process.Start(thePSI)

   

  does this not work for you If it works, it should shutdown the computer after 10 seconds

   

  alternatively you could try this method but wouldnt recommend it (permission issues perhaps but also you are P/Invoking which can be expensive sometimes)

   

  imports System.Runtime.InteropServices

  It works at last but I'm curious how

  Process.Start("shutdown /s")

  doesn't work.  It says it can't find the file and this doesn't work either...

  Shell "shutdown /s"

  process.start(SystemDirectory & "\shutdown /s")   - can't find file

  However,  Start| Run| Cmd |shutdown /s    does work... so the OS is able to

  find shutdown from any directory, but with shell or process can't.
