Hi all,

I've coded a program to monitor the printing activities, so how would I make a service to prevent closing the program or let the user close it but the program still work in the background as it's service still running.

Also, I prefer to use a built-in service in an installer that does the same.

Thank you.

What I have tried:

what I'm thinking of is to make a service that monitor the process and prevent the program from closing by not to let the user terminate the process.
is there any better suggestion?

If it's an activity of monitoring, why is it a program? Make that itself as a windows service that runs on the system and capture the print activities and log it.

User is not even interacting with it and thus no need to worry about preventing closing of an app which is not good even if you achieve.

it's actually a software with a UI, such as some controls to adjust what to monitor, but what I want to keep monitoring even if the program is closed.

Yeah, you can't prevent the app from closing. You can see that the process goes away and relaunch it, but even that's a pain in the ass to do as your service has to launch the process as the logged in user (there could be MULTIPLE people logged in at the same time!) AND you have to make sure the process gets launched on the correct desktop, an even bigger pain in the ass.

So there is no a built in service to so that, I mean an installer has this feature?

No, there is no built-in way to do that, and NO, an installer does NOT have this feature.

The "feature" you're talking about is the Restart Manager. It can NOT restart applications as the user if the installer (or your service) is running as LocalSystem. It can only do that if the installer is running as the user that's logged in.
