~First of all, to start all components of TCP/UDP chat program, you need to open "startChat.bat" file.
~It will open files automatically.
~Then, three command windows will pop up.
~One which has "Waiting for connection..." printed in the screen is your "Chat_Listener", which is important for gathering data from bounded address and send it to your client for your chat connectivity.
~Other one which has "Enter a name: " printed in the screen is your "Service_Advertiser", which sends your JSON String that contains your name and IP address to the other Listeners in the network. So you should type your name in order to introduce yourself.
~Last one which has nothing printed in the screen until it gets some JSON data from other Advertisers is your "Chat_Client". It's main file for Chatting, because it's doing many things together like listening for online users, adding them into python dictionary and chatting with a chat interface that contains all of messages that sent or received.
~So, our program will wait 30 seconds for listening online people on the network and add them into the dictionary. After 30 seconds, you should type a index number for which person you want to chat with.
~(P.1) After that, a chat interface will pop up and you will type your chat username. After pressed "Enter", if other person is connected to you properly, than you can chat with him/her freely. If you want to quit from chat, just type "{quit}" and press "Enter" or if you close the chat window, this will be done automatically.
!!IMPORTANT!! ~Before typing index number, when you can't find that person you want chat with after 30 seconds, than you can open "Service_Listener" for checking online persons. If he/she is online, just close "Chat_Client" window and reopen it for new scan.
~After 30 seconds from opening "Chat_Client", If no one is online, than you can type that person's IP address on your own or just close the "Chat_Client" windows and reopen it.
~After reopening, you can follow (P.1) part for rest of them.
