Optimal Way For A Service To Interact With User
Feb 10, 2011My application needs to be a service (it needs run regardless of whether a user is logged on), but I also need some sort of client control/oversight over what it is doing. What is the optimal way to do this?Write a separate application to communicate with the service application - I see that as best solution in terms of stability, since the applications will be decoupled somewhat Use callbacks on system events in the service application to load UI forms directly from the service application - I see this as being easier to deploy.

Show User Form On A System Service Event Via IPC Remoting?
Jul 7, 2009I am struggling with this issue for serveral days now.My application needs to work like wsus (windows updates) does. On a certain event triggered by a windows service working under SYSTEM account it needs to show a (second) form under the user context.The IPC Remoting works fine so I think my issue is in the threading.When I use form2.Show() form2 appears but the form freezes.When I use form2.ShowDialog() the form appears but I cannot get the focus on it.
