Question

I have an application, written by me in C#.net 2.0 – when the application is opened, a timer will check every 3 seconds for x. If x happens, it shows a warning in a windows form.

Is there a possibility to install this timer and the windows form call in a windows-service? So that the timer ticks every time a system is up and shows the message then?

1. No, it is not possible to have a service display a form. This is by design, since a service is supposed to run without a user interface
2. You can have a regular application that communicates with your service and displays the warning, but I don’t know how exactly this is done.
3. IMO, you don’t need a service, just create a regular application without a main form that runs in the background, performs your check, and displays a warning when necessary. You can add that application to the Run section of HKLM or HKCU, so that it is always started when a user logs on to the system.
