Example()

Func Example()
    ; Set Some reusable info
    ;--------------------------
    Local $ConnectedSocket, $szData
    ; Set $szIPADDRESS to wherever the SERVER is. We will change a PC name into an IP Address
;   Local $szServerPC = @ComputerName
;   Local $szIPADDRESS = TCPNameToIP($szServerPC)
    Local $szIPADDRESS = @IPAddress1
    Local $nPORT = 33891

    ; Start The TCP Services
    ;==============================================
    TCPStartup()

    ; Initialize a variable to represent a connection
    ;==============================================
    $ConnectedSocket = -1

    ;Attempt to connect to SERVER at its IP and PORT 33891
    ;=======================================================
    $ConnectedSocket = TCPConnect($szIPADDRESS, $nPORT)

    ; If there is an error... show it
    If @error Then
        MsgBox(4112, "Error", "TCPConnect failed with WSA error: " & @error)
        ; If there is no error loop an inputbox for data
        ;   to send to the SERVER.
    Else
        ;Loop forever asking for data to send to the SERVER
        While 1
            ; InputBox for data to transmit
            $szData = InputBox("Data for Server", @LF & @LF & "Enter data to transmit to the SERVER:")

            ; If they cancel the InputBox or leave it blank we exit our forever loop
            If @error Or $szData = "" Then ExitLoop

            ; We should have data in $szData... lets attempt to send it through our connected socket.
            TCPSend($ConnectedSocket, $szData)

            ; If the send failed with @error then the socket has disconnected
            ;----------------------------------------------------------------
            If @error Then ExitLoop
        WEnd
    EndIf
EndFunc

Well there needs to be another program to receive the data... it is failing because you don't have any other programs "listening" for connections then "accepting" the connection.

Look at the TCPListen function
