interactive services 1

[zildjohn01]

hi, i have a question about .net services.

i would like to create a service that creates a tray icon and a window on the current desktop. When a new user logs on or the desktop is switched, i would like to be notified, then move my tray icon and form to the new active desktop.

I read about interactive services on msdn, but didn't see anything about tray icons. Could tray icons be managed in a service? Is there a way to get notifications of user changes?

Thx in advance for any help,
John

Services, by their nature, don't interact with the desktop. This is because they run when Windows starts, and not when any user logs in.

What you can do is write a service to do "the real work", and then write a tray icon application that communicates with the service via one of the inter-process communications methods (sockets, named pipes, etc), and have the tray icon in the user's startup group.

thanks -- what would really be nice for my app though is to have a global keyhook (such as ctrl+alt+shift+s) to halt (cleanly) my service, even if a user is not logged in. if that is not possible, though, what you described will work fine. thanx so much
