SimpleChat is a simple chatting script which allows you to chat over a network (LAN) or not over a network mean anybody in the world(WAN)
this script depends on the batch files it creates

You can send messages by Entering the LAN or Wan IP or Name of pc in the IP Address Box (Picture Below)



An Example of a WAN IP Address is 24.177.17.74

An Example of a LAN IP Address is 192.168.1.101

An Example of a PC name is Laptop01 (This is another way of LAN)

Type your message in the Message box and press Send it will send your message and a msgbox on the desired Computer will popup with your text

DISCLAIMERS
To receive messages you must have this script open

WAN sendings might not work with people who have Routers

This program is in v0.1 aplha stage and will be improved in the future

In the program it tells you your LAN and WAN Ip

POST YOUR IP

Post your ip in this topic maybe we could have a ip directory of everybody here

Script : SimpleChat.ahk

Cool script but net send is disabled where I work (and many corporate locations I think) and my WAN IP at home is my router Maybe net send supports ports so they can be forwarded?

collecting ips is not always a clever idea, especially not in a public place like this forum - i doubt that people 'd give you their static ip's so these can be published and accessed by whoever wants to, when they know what they're doing.

depending on where you live and how you access the internet, many ISP (internet service provider) use dynamic ips. so collecting these is pointless, because these change everytime you dial in or connect to the net.

to make up a chat which works over WAN some centralized instance will be needed. take a look at how peer-to-peer networks (bittorent for example) are organized to get the idea.

my 2 cents

Ok ips is not really that good

but this script enables net sned when you start it

When you end the script it disables net send

in most corp and workplace environs this is not possible

fry, everybody startet as a n00b the other day. even me - i'd say im still a n00b, just got some more expirience but u know ... than more i learn then better i understand how little i know.

when you plan to make the ultimate chat with ahk - i might assist you in answering your questions and even help you with the code. i also can give you ideas of how to 'make' things.

for example ... an ahk chat should be a scripted chat only no external dependencies

2nd it'd be good to have the script working everywhere ... even behind firewalls and NATs .... much the way skype works ... e.g. 'hijacking' some popular protocols like http on port 80 or ftp on port 21 and sneaking that way thru the firewall.

3rd i server might be needed to connect all people without presenting their external ips to the public - also some sort of security would usefull - eg crypted data streams - so no one can use the read datastreams (tcpdump - ethereal etc). i'd prefer a service where user have to sign up otherwise the chat works only with restrictions ... like nomore than xxx chars and 2 answers/minute or smething like that

filetransfer 'd come in handy - especially when not directly connecting between users and this as a toggle feature so use might establish direct connections - knowing that this 'll expose their IPs

different 'channels' - private channels - moderator feats - 1 on 1 ---

the feature list is nearly endless - each has its own advantages but also disadvanatages.

i think the important thing is to have it small and robust, so it can be used in every situation.

let me know if you need help

greets

@fry
i sincerely hope you do not mistake my comments as ridicule
those who have posted responses are merely trying to point out some conceptual issues that are faced with these types of applications in the real world thinking perhaps you may have overlooked them

in one shape or another we are all noobs when we look at other peoples ideas in the fact that its a new idea that no matter the level of experience do not see the same picture as the person presenting it.
the idea of the forum is to discuss the value of these idea's and viability of working code when it works.
Yours does seem to work however many who posted have tried in earnest to present some conceptual issues that in the eyes of some you "seem to have overlooked"

we are not poking fun only helping you see the whole picture

[hello]

i know this sounds strange but i have a LAN network chat system, is there anyway i can implement this into the full featured chat?
it can
1) send user list to a ftp, then download user lists with status every second (to make it work)

2) allow private messages

30 allow users to connect to one ip address (that of the server for the chat) and chat

think it would help if you (the Original Poster) could clarify the exact protocol and methods used. I know this can be gleaned by reviewing the code, but I think it would help the general flow of this thread if these details were stated up front.

For instance:

Does this program connect client-server direct TCP/IP, or does it send out a broadcast/multicast message via UDP for anyone who might be listening? What ports might a user need to open in their firewall and/or hardware router? And finally, what protocol (data structure) is being used to format each packet; does it use and conform to an existing protocol or is it simple <text><newline>?

All these questions and more...

[tank]

net send is well documented on msdn
the origional poster really doesnt need to re document this
