How to receive event when network is connected and also when user logs in

Question

I have a service that runs and I\'d like to receive notification when:

a) the network is connected.

b) when a user logs in to the machine.

How can I do

Answer 1

You can't do b) with .NET 2.0. For XP and before, you need to create a GINA replacement, which is an unmanaged DLL which exports a specified set of functions.

In Vista, there is a different COM-based model which you have to use which you might be able to use .NET 2.0 for, but I wouldn't be surprised if you can't.

What I would do is have your GINA replacement (or the equivalent on Vista) send a signal of some kind to your service.

For a) these two links should be able to help:
