This code looks great, but my version of Visual Studio is telling me the System.Management class doesnt exist!!! Is this something to do with my complete beginners ignorance? Im trying to force a pc to shutdown with the following code: System.Diagnostics.Process.Start(@"C:\WINDOWS\system32\shutdown.exe", "/f /t 00"); But the force doesnt work like i would expect it to in DOS. Any help that anyone could give me would be great. And the simpler the better... I think i may be in slightly over my head at the moment!! But what better way to learn?!?! :) Thanks alot.

Scroll down to the bottom of this posting: http://www.codeproject.com/csharp/wmi.asp?df=100&forumid=7082&exp=0&select=1341200 ...look for the comment "Here is the code I use to shutdown the PC using WMI:" Shutting down a pre-XP operating system is easy enough, XP and upwards takes a little more effort.

Add a reference to System.Management, add it to your using clause. The following code should point you in the right direction: public enum ShutDown { LogOff = 0, Shutdown = 1, Reboot = 2, ForcedLogOff = 4, ForcedShutdown = 5, ForcedReboot = 6, PowerOff = 8, ForcedPowerOff = 12 } private void button2_Click( object sender, EventArgs e) { ManagementClass W32_OS = new ManagementClass ( "Win32_OperatingSystem" ); ManagementBaseObject inParams, outParams; int result; W32_OS.Scope.Options.EnablePrivileges = true ; foreach ( ManagementObject obj in W32_OS.GetInstances()) { inParams = obj.GetMethodParameters( "Win32Shutdown" ); inParams[ "Flags" ] = ForcedShutdown; inParams[ "Reserved" ] = 0; outParams = obj.InvokeMethod( "Win32Shutdown" , inParams, null ); result = Convert .ToInt32(outParams[ "returnValue" ]); if (result !=0) throw new Win32Exception (result); } } Remember to save your work before you test this code!
