[madmorgan]

hello all,

im trying to build a very simple chat program were to users can use it of course. im still a binggner but im trying my best with this program and enjoy it. But any way downto the program.

you can run my code to see what im doing, the program has a GUI with a inputbox for the ipaddress to send to. and a edit box for the message but i also want the same program to recive messages as well in a sepreate input box on the same program, i know there will be a problem with the TCP Port numbers any way how can make lision on all ports as well so i dont have to give it a fixed port???

please i need help with this. here is my code.

#include <ButtonConstants.au3>
#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <WindowsConstants.au3>

Global $Form1_1 = GUICreate("", 475, 256)
Global $Edit1 = GUICtrlCreateEdit("", 8, 112, 185, 89)
GUICtrlSetData(-1, "")
Global $IPAddress = GUICtrlCreateInput("", 8, 56, 121, 21)
Global $Label1 = GUICtrlCreateLabel("Enter The IP Address Of", 8, 16, 123, 17)
Global $Send = GUICtrlCreateButton("Send", 8, 216, 75, 25, $WS_GROUP)
Global $Exit = GUICtrlCreateButton("Exit", 120, 216, 75, 25, $WS_GROUP)
Global $Label2 = GUICtrlCreateLabel("E.G 192.168.1.65", 144, 64, 90, 17)
Global $Label3 = GUICtrlCreateLabel("You Message...", 8, 88, 78, 17)
Global $Label5 = GUICtrlCreateLabel("The Person You Want To Chat To.", 8, 32, 171, 17)
Global $edit2 = GUICtrlCreateEdit("", 272, 32, 185, 89)
GUICtrlSetData(-1, "edit2")
Global $Label4 = GUICtrlCreateLabel("I Want This Edit Dox To Show The", 280, 128, 170, 17)
Global $Label6 = GUICtrlCreateLabel("Recived Messages", 312, 152, 95, 17)
GUISetState(@SW_SHOW)


While 1
    $nMsg = GUIGetMsg()
    Switch $nMsg
        Case $GUI_EVENT_CLOSE
            Exit
        Case $Exit
            Exit
        Case $Send ; want this to keep sending new messages when the user enters them.
            TCPStartup()
            $TCPCONNECT = TCPConnect(GUICtrlRead ($IPAddress), 403)
            if $TCPCONNECT = -1 Then Exit
            TCPSend($TCPCONNECT, GUICtrlRead ($Edit1))
            TCPShutdown()
    EndSwitch
WEnd

; i also want this script to recive messages as well so here is my
; recive code.

and this is a sparet bit of code ive been testing it with to make sure im sending data. but i would like to have this in the same program as well. so it recives messages as well. BY THE WAY YOU NEED TO HAVE THIS RUNNING FIRST TO SEE IF DATA IS BEEN SENT.

TCPStartup()
    $TCPLISTEN = TCPListen(@IPAddress1, 403)
    Do
        $TCPACCEPT = TCPAccept($TCPLISTEN)
    Until $TCPACCEPT <> -1
    Do
        $TCPRECV = TCPRecv($TCPACCEPT, 1000000)
    Until $TCPRECV <> ""
    MsgBox(0,"Incomming Data", $TCPRECV)

Thanks

Hi, i have create this script based on AutoIt Help. You should try to explore and read the AutoIt help file, there are many things in it that should solve your problems.. This is just a simple script, but i added some functions such as SoundPlay and WinFlash when you received messages..

Hi, madmorgan.. For your information, i have tried your code. But things changed, i already mess up the script and now its unusable.. I don't know what is wrong with your code but when i write my own code, its working! I have no idea about your script.. You can compare my code with yours, maybe you can find something.. Good luck!
