You can use the TServiceManager component to detect whether a service runs.
I have coded this component, it is in active use in commercial projects.
But there is a strange thing about your story: as of Windows Vista, service
applications can no longer display a window on the desktop, Windows no longer
allows that. So probably, the window is displayed by some other program that
comes with the service ?
You can send a keypress to this program's window with the FindWindow call to
get the handle and then use a PostMessage() call to send a click or keypress.
Michael.
