Batch_Chat - v1.1

A chat made in Batch of all things. This chat was first created in 2011-2012 when I started to get interested in programming. Now it's 2014, and for no logical reason, I have started to improve it. It cannot communicate over the internet directly, it can only send messages locally on your network. BUT you can use Hamachi or a similar program to chat over the internet.

Features:

Local Area Network (LAN) chat
Support for Virtual LAN IP's
Group chat
Colors (via colous binary)
Sound notification
Quick start
Help and command inheritance (for future ranks)
Argument -reset to reset all data
File encryption (very weak, look below for more info)

Commands:

/afk - Says you've gone afk
/back - Says you're back
/cls - Clears your screen of previous text
/clsfile - Clears the chat file
/help - Lists all commands and their description
/history - Loads chat history
/host - Changes the host computer to a LAN/Virtual LAN IP
/list - Lists players online
/me - Say stuff about yourself
/quit or q - Quits the chat properly (PLEASE USE THIS OR ELSE /list IS USELESS!)
/say - Prints server message

Plans:

~~Add custom network drive/custom setup~~
~~Add file encryption with crypt binary~~
Add rooms
Add legitimate ranks
Add an update system (eh, might as well)
Add encryption command
Add more creative, fun, enjoyable commands
Add custom commands
Add encryption in the portion of the Batch_Chat itself where it actually encrypts the chat to stop possible decryption from viewing sourcecode.
Review chat bugs and delay due to encryption

Compatible with:

Windows
Wine
DOSBox (if I remember correctly)

Quick Instructions:

run "Batch_Chat.bat"
follow the onscreen instructions (tip: you need a host before there can be a client)
run Batch Chat again
type "/q" into the "Messages" window that comes up
run Batch Chat again and everything should be working well. You can now send messages using the Messages window

Note: when connecting to a host, you may need to be authenticated. For example, my computer has a username and password, so client computers had to put in my username and password beforehand in order to connect. A good sign you need to authenticate is if the Batch Chat keeps asking you to input the host computer's name. To authenticate, open File Explorer and click Network on the left to view your Network Connections. Find the host computer and try to double-click it. It should prompt you with a login if it is required. After that, you should be able to see the shared "chat" folder. If you do, you are all set.

There is a way to remove the restrictions though so no one needs your computer's username and password. To do this open the "Network and Sharing Center" on the left click "Change advanced sharing settings". Click the dropdown for "All Networks" then click "Turn off password protected sharing" and turn on "Public folder sharing".

Note 2: if you wish to connect to a host over VLAN (like using Hamachi), then you should go ahead and set up as a host and once the chat is working correctly, use the "/host" command to switch to a VLAN host.

Note 3: if you are having trouble figuring out your computer name, I have created a Batch file to help you out. On the host computer, open "Batch.getComputerName.bat", use the name it gives and you should be good.

Lastly, if you have any problems, just open up an issue and I'll be happy to help you.

Color codes:

To use color codes while chatting, simply type "[<insert color code>]<my text>". So, for example, I could type "[12]Hello [5]world[12]!" to send a message that looks like this:

Here's a key for the color codes:

File encryption:

The file encryption I implemented on this is extremely weak. Not that I expect highly sensitive material to be sent using my horrible Batch Chat, it's just the bare minimum to prevent users who aren't familiar with programming from giving themselves a higher rank (if a ranking system is ever implemented) or changing what people say. People can clear the chat log unfortunately, but nothing too devious.

If you want to make it harder for people to decrypt the chat, you can do two things. 1, you can change the encryption/decryption key from the default key that I use to a different one. And 2, it is possible to store the chat in an exe file. That way the encryption/decryption key isn't as accessible. For more info, look into this program.
