I will make more checkings tomorrow (probably, if I can).
The original project (.rb !) dates from 2005-10 (or 11, probably too). Unfortunately, I do not do screen shots then, and the Carbon application… cannot be run (and I do not have an older enough computer to run Carbon).
I do not recall what I get - then - in the Listbox’s list of registered users (on line users in that group), but who recalls an IP address is Joe’s Newbie IP Address (this seems logical to provide a name).
@Julian S Even if its a public WiFi hot spot you're still connecting to the private network provided by the public WiFi hot spot which probably wont have internal DNS names for its internal IPs.
I remember that I do not have to be registered in the Hot Spot to be able to communicate.
Also, earlier today when I made my tests, I was not able to go to the Internet, but I saw the HotSpot name and connection window.
@Julian S You need to come up with an alternative method of resolving a username for example, the user enters a name when they start the app and this is transmitted on connection.
Or checking the computer user name ? I forgot how, but I remember its possible to get that (someone shared that information years ago).
Ah, the ins and outs of the brain memory ! (and this goes wronger day after day,).
