Reboot Machine with VB.NET 1

[reffek]

What code would you use to reboot a maching using VB.NET?

Windows has a built in .exe called shutdown. If you go to the command prompt and run "shutdown -?", you should be able to see a list of all valid switches.

I haven't tried this code out, but it should give you the general idea.

System.Diagnostics.Process.Start("shutdown -r")

or

Shell("shutdown -r")

Of course it is not working. You need to pass the "-r" as an argument, so:

System.Diagnostics.Process.Start("shutdown", "-r")

-bclt

It seems c:\windows\system32\shutdown.exe exists in WinXP but not in Win2K. Any suggestions for VB.NET rebooting under Win2K?

You have to add a reference to the management. Found this, but not tested:

Dim result As Int32
result = 0
Dim scope As New Management.ManagementScope( _
"\\localhost\root\cimv2")

scope.Options.EnablePrivileges = True
scope.Connect()
Dim oq As New System.Management.ObjectQuery( _
"SELECT * FROM Win32_OperatingSystem")

Dim query1 As New Management.ManagementObjectSearcher(scope, oq)

Dim queryCollection1 As Management.ManagementObjectCollection = query1.Get()
Dim mo As Management.ManagementObject
For Each mo In queryCollection1

Dim ss As String() = {"6", "0"}

mo.InvokeMethod("Win32Shutdown", ss)
