How to use the chat software:
1. After running Server and Client, first start the server and click Connect, then click the client Connect.
2. When the prompt on the upper right becomes waiting connect... and connect succeed, you can achieve duplex sending and receiving of messages.


ps: The upper left corner shows the real-time message. Click the recvmsg button to record the current message and display the message in the box.
