P2P-Style Chat

[spyrorocks]

It has been too long since I have posted a project on here. I will be posting more frequently now.

Anyways, without further to do, here is P2PChat v1.0

Download: P2PChat.zip

P2PChat is a serverless chat app to be used in your local LAN. Each running P2PChat app will send out a beacon UDP Packet to every PC within your subnet to try to find other clients that are in your same channel to connect to.

Each client is completely independent from one another, allowing for a strong network.

Please note, this has been tested with AutoIt v3.2.10.0

Features:

-Smilies

-Auto-Connection to other clients upon start up

-Different Channels for chatting in

-List of users online

Bugs:

-Client Crashes when you disconnect from a channel, connect to a new channel, the connect back to the old channel.

Comments appreciated.

It wouldn't run on 3.2.10.0 so I changed it to use guilistbox.au3 so it runs on beta 3.2.9.14 without errors.

Apart from that it works very well.

If you use Scite then I think your script wold look better if you 'tidied' it.

Would be good IMO if chat scripts had a panel for someone to send a picture. Maybe put the edit for connected users on a tab control and have a page for attachments.

EDIT: I hadn't noticed that you've used IECreateEmbedded, so you could add pictures.

The smilies work well.

Good work, keep going.

Where you use TCP? I've seen only UDP.

You should improve teh chat. see the my UDP chat.

global $udpsock = UDPBind($ip, $udpport)

;-----
;more code

if $recv = "PORT TEST" then
udpsend($UDPSOCK, "OK");
endif

does it work???

mmmm, dude, I am not an expert on network programming but you missed something, the only way (I think, or at least the only reliable one) to create a serverless chat program (or any other kind of network traffic without any centraliced server, like quake servers for example) have to be programmed using ONLY UDP protocol + multicasting. So TCP is the best protocol for client-server applications but when talking about serverless applications you have to forget TCP and center only on UDP. (Someone with more knowledge than me correct me if I am wrong).

Sorry!!

I've seen after.

He uses both, TCP and UDP.

global $tcpport = 1628
global $tcpsock = tcplisten($ip, $tcpport)      
;-----
;more code
;-----
case left($in[0], "REQ USR")
        tcpsend($in[1], "USR "&_stringtohex($username)&@crlf)
;-----
;more code
;-----
func check_newusers()
local $user = tcpaccept($tcpsock)
if $user > -1 then
;-----
;more code

Cool I like how you used HTML for the smilieys. I hope you don't mind if I snag that bit of your code for a TCP chat I'm making!

Oh, I see. Although I was only traying to explain why the need of UDP for a serverless client. I am not sure but I think multicasting is only possible using udp protocol.

I love using network functions in autoit scripts. as long as you give me credit where necessary, its all good.

This is just my method of a serverless lan chat app.

Just had to comment, this thing is pretty cool, it's really helping me out with the lan P2P concept! Thanks!
