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 could write a WinLogin Notification package. However, I am not sure if it is possible to do in C#. (I have no reason to believe it isn't, but I have only ever done it in C++ and unmanaged code.)

Here is a CodeProject link

I don't know how to listen for when the network connects.
