First of all, in your server, to recieve data, you use the connected socket identifier(as returned by TCPAccept) not the main socket identifier(returned by TCPListen).

Also in your client-script, because of that the script exits instantly after sending the bytes, causing the connected socket to be invalid(causing the server to miss the message as the socket gets disconnected).

Modified your code a little:

Server:

TCPStartUp()

$sListenAddress = @IPAddress1
$iListenPort = 8084

$iMainsocket = TCPListen($sListenAddress, $iListenPort)
If $iMainsocket = -1 Then Exit(MsgBox(0, "Error", "Could not create the listening socket"))

While 1
    $ConnectedSocket = TCPAccept($iMainsocket)
    If $ConnectedSocket >= 0 Then
        $info=TCPRecv($ConnectedSocket,512)
        msgbox(0,"Display message !",$info)
    EndIf
    Sleep(250)
Wend

Client:

TCPStartUp()

$g_IP = @IPAddress1
$Message = "Hello World"

$socket = TCPConnect( $g_IP, 8084 )
TCPSend($socket,$message)
Sleep(2500); Sleep some to keep the connection open, allowing the server to parse the message
