how to check computer's state using Qt?

Question

i\'m trying to get computer\'s state in my LAN... thought about using QTcpSocket but it\'s not realy effective since port also should be inserted as:

socket-         


        

Answer 1

Are you trying to check if your local machine is on the network or if a target machine is ?

There isn't a good cross platform way of doing this. The nearest on qt is QNetworkInterface, and check attribute "ISup" - it's not perfect, it may be active if you have a network cable connected but just to a router, and inactive if you have a 3G modem but aren't on a call.

On Windows check InternetGetConnectedState()
