Help need with sockets again (nearly there though!)

[brendanmcdonagh]

Hi all,

I have my little message program working until i press a button and then it'll go to actionPerformed method, and stop reading but will keep sending a message which is being received. Obviously, this is because the send is in the actionperformed method but the read is in the main method. Anyone offer any solutions to getting my program reading again after actionmethod() has been called. I ve tried to just create a method for read which is called at the end of main method and then at the end actionperformed() method but got a load of errors to do with static variables and methods.

I ll paste my code, any help is appreciated.

p.s. this is my first attempt at kind of networking so it might not be designed that way, it's just been trial and error for now!
