Text Passing

[Yorkiee]

hi, i have a problem with my client/server chat gui application. i have the client and server talking back to one another through the gui's and the text that is entered is displayed when it is sent. I have to 2 textfields in each frame, one for sent and then one for receive. when the client sends text to the server i want the client to see what they have sent in the receive textfield within the client frame. i also want this function on the server side as well i know you can append the textfield but i want to design a new thread for this. im using just one thread in my client and server code but i want to use another one, maybe design a new class and a new thread within this.
>>> could u help me out with some ex code
>>> i have included code this time!
