This is a bit odd. We have PC systems out in the field that may or may not be connected to the internet.
I'd like to implement something so that when they are connected, and my app is run, it simply sends a string of data to a server here, from which I can check how many times they have run the app that day, just a kind of "phone home" check.
Clearly we have a fixed IP address, but network stuff is currently something I know nothing about.
Does anyone have any ideas how I can do this?
Cheers
