There's my code.

Could anyone tell me why it immediatly terminates when I run two of them? The goal was to have peer to peer chat but it doesn't work out so well... Could anyone also tell me what I could do to improve the code?

Could you please change your code tags to autoit tags to make it easier to read? Thank you.

[Shyke]

I don't know how to - would you mind specifying how?

[Snarg]

Paste your script into the message. At the start of the scirpt put:

At the end of the script put:

[Shyke]

Task completed.

Thank-you, I was unaware of that feature.

1. You do not seem to close your Group ( GUICtrlCreateGroup ("",-99,-99,1,1) )

2. You do not show your gui ( GuiSetState() )

See how it goes with correction.

This function does not look right. Why is it calling it's self? Here is a peer-to-peer chat example. Take a gander at it and it might point you in the right direction.

Func mCall()
    If $handshake < 2 Then
        $mCallSocket = TCPConnect($serverip, $port)
        If $mCallSocket = -1 Then
            mCall()
        Else
            $handshake = $handshake + 1
            mListen()
        EndIf
    EndIf
EndFunc
