Hi everyone, I'm trying to create a program that you can use to communicate to other people with the same program. It connects to a Server program that gets your message an send it to everyone. I found 2 problems that I haven't been able to solve.
The first one is that,in NetBeans, the GUI looks OK, but when you run the program outside it, the GUI becomes horrible. (Screenshots are on the attachments)
The other, more important problem, is that I seem to be only able to connect to localhost, even if I put my IP (I looked it on whatismyip.com , is that okay? ), it apparently connects, but it doesn't work. What should I do?
If you need any more info, just ask.
Thanks in advance.
