Simple one to one chat over internet

8 posts in this topic

Hi,

I want a simple script to enable transmission and reception of text between 2 computers on the Internet without using GUI,

specifying in scripts these variable data:

$serverip

$port

$texttosend

$receivedtext

To test it, a msgbox will display received data when is received, and to input text to send, use InputBox in loop.

I'm beginner in autoit.

I need only one connection, no need fore more.

Please help me.

You want to first do some basic autoit3 scrips.

Then you want to look at TCPStartup, UDPStartup and all of its related functions.

You may also want to look at 403 forbibben video tut on the subject

Thank you

I can't offer something very simple, but you may learn out my old creation:

Completely working(excluding some extra things) lan/internet chat, with sounds and traytips,

client and server(2 in 1) - who started first, - is server. If you are connected and server disconnects,

then client becomes server and listen for incoming connection:)

To connect, you must specify IP address of remote computer inside INI-file,

or (if you have a site) to upload your IP:

#include <Inet.au3>
_INetGetSource("http://www.yoursite.com/ip.php?ip=" & @IPAddress1)

$ip = _INetGetSource("http://www.yoursite.com/file.txt")
if Ping($ip) <> 0 Then MsgBox(0, "Uploaded IP", $ip)

contents of ip.php:

<?
$file = "file.txt";
unlink($file);
$Handle = fopen($file, 'w+');
$ip = $_GET['ip'];
fwrite($Handle, $ip);
fclose($Handle);
?>

and then use _InetGetSource instead of read/write IP from/to ini file..

Thank you, Godless, but i want some basic stuff.

I tried the following codes, but without success:

CLIENT:

TCPStartup()

$ip = "86.34.52.138"

$connect = TCPConnect ( $ip, 216 )

if $connect = -1 Then
    TCPShutdown ( )
endif
    $datatosend = "Hello!"
TCPSend( $connect, $datatosend)

endif

SERVER:

$ip = "86.34.52.138"

TCPStartUp()

$MainSocket = TCPListen($ip, 216)

$ConnectedSocket = -1
Do
  $ConnectedSocket = TCPAccept($MainSocket)
            
Until $ConnectedSocket <> -1
    $recv =""
    While $recv <> "exit"
   $recv = TCPRecv($ConnectedSocket, 2048)
    
    If $recv <> "" Then 
     MsgBox(4096, "Test", "$recv", 10)
     endif
    
Wend

Note that the other computer have another static ip in scripts.

How to do it? SIMPLE! After that, i will do experiments.. to learn more.
