Shutting down Windows

[viper123]

Hi folks!
I want to make an application which shuts down the machine. Could you tell me how to do this? I've tried to use ExitWindowsEx, but it doesn't work on win98 OS. It says it works on Windows NT only.

One day i downloaded a component to do those thing but it didnt' work
here I leave the code, check it & fix it, think that is just a little detail

sorry for not indent like normal but I just copied & paste it

The instruction that you metioned works in win 9x & Me, but not in NT, because you need some privileges to shutdown the system
