Answer 1

Services run in Session 0, which has a different Window Station and Desktop assignment to other sessions where users interact with the system through their visible desktops.

You'll probably want to have your service switch to an active users' session to establish a link to their visible desktop in order to create a snapshot of it - your screenshot code is working as-is, but is taking a snapshot its own Desktop (which is nothing).

This might help clarify things for you.
