How can I confirm TCPStartUp has started?

Recommended Posts

Hello, I'm trying my hand at a simple TCP server and client but I have a bit of a worry! I create a simple GUI to return the error code following the TCPStartUp command and its returning an error! I have tried using some example TCP Scripts too which don't seem to work properly. 

Would someone mind having a look at my code below and tell me if the TCPStartUp should be working? Should it be returning errorcode 1? 

And should my text steps be TCP Listen > TCP Accept > TCP Recieve?

I'm a bit of a noob so any help would be hugely appreciated :)

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

Opt('GUIonEventMode', 1)

$GUI = GUICreate("S.M.I Server", 472, 311, 751, 312)
$Content = GUICtrlCreateEdit("", 8, 8, 313, 289, BitOR($GUI_SS_DEFAULT_EDIT,$ES_READONLY))
GUISetState(@SW_SHOW)

GUICtrlSetData($Content, "Content")

TCPStartup()
IF @error == 1 Then
    GUICtrlSetData($content, "TCP Services started with: " & @Error)
Else
    GUICtrlSetData($content, "TCP Services failed with error: " & @error)
EndIf

While 1
        GUISetOnEvent($GUI_EVENT_CLOSE, "quit", $GUI)
WEnd

Func quit()
    TCPShutdown()
    GUICtrlSetData($content, "TCP Shut Down: " & @error)
    sleep(700)
    Exit
EndFunc

try this:

; == Start the TCP service.

Example()

Func Example()
    Local $vTCP = TCPStartup() ; Start the TCP service.
    If $vTCP = 1 Then
        MsgBox(64, "", $vTCP)
    EndIf
EndFunc   ;==>Example

Correct answer, learn to walk before you take on that marathon.

​I assigned a variable to TCPStartUp() as you did and this returns the error code I'm now expecting within my GUI!  Thanks.

Next step is trying to get another script to talk to this one.

You don't really need to hardcode the 1, If $vTCP Then is enough as anything that isn't zero is consider True, with zero meaning False. This is the beauty (or ugly side) of dynamic languages.

      I started working on this program in the summer of 2008 then I stopped cause I faced some problems I couldn't overcome back then. Now that I've practiced more and have become a better scripter/programmer I'm releasing the program to the public to get some opinions. I know it's not a new concept but it's the first program I started besides some small stuff I did just for practice! I won't post the source code yet because it's still under construction, although I'm sure I've posted early stages of the code with bugs in the past in some topic...
      What I wanted was a simple, small, serverless program that would work without installation cause I wanted it for where I work, so I ended up with this!
      I have attached some images of various versions, also visit the forum thread.
      The package includes s!mpL3 LAN Messenger and the full change log.
      Current version 2.9.9.1! [04/07/2019]
      Check the Change Log below!

      edit: this is probably in the wrong place, can a moderator move it to wherever it belongs?
      ----------

      is there any way to completely disable TCPTimeout and make TCPRecv() wait indefinitely? maybe setting it to 0 or -1 or something? 
      the docs doesn't seem to mention any way to disable it

      - the underlying C code would set SO_RCVTIMEO to 0 , aka

      DWORD timeout=0;
      setsockopt(s, SOL_SOCKET, SO_RCVTIMEO, &timeout, sizeof(timeout));

      I have had several people ask for this, so I decided to work the algorithm for it and this is the result.
      What is it?
      A Gateway Proxy Sends and Receives Data Unmodified.
      https://en.wikipedia.org/wiki/Proxy_server
      What is it used for?
      You can use it as a gateway, relay or router between two known static IP addresses.
      More information is in the header of the script.
      Download: LocalGatewayProxy.au3
      You will need WSA_NBTCP.au3 from here:
      https://www.autoitscript.com/forum/topic/191954-wsa_nbtcp-v100-udf/
      If you have any questions or problems, let me know.

      This script is based on algorithm code from EnrMa.
      Updated: January 22, 2018
      Made improvements. Changes are in the script header.
      Known Issues: AutoIt x64 does not work properly with this script.
      Download: LocalProxyServer_v1.00.zip
       
    • By ripdad
      WSA_NBTCP.au3  (Windows Sockets API - Non-Blocking Transmission Control Protocol)
      Version: 1.00
      Type: UDF
      This is an accumulation of WSA code from many sources and modified to suit myself.
      These functions have been thoroughly tested using a Local Proxy Server, which
      is about the most strenuous test you can use.
      Includes my rendition of how a TCPRecv Timeout should work. Also includes a
      timewait/timeout using Select for TCP Send, which works great for that function.
      You will need a loop to use _WSA_TCPRecv(). An example will be forthcoming in a second post.
      Functions:
      #CURRENT_USER_FUNCTIONS
      _WSA_Cleanup
      _WSA_FormatMessage
      _WSA_GetLastError
      _WSA_TCPAccept
      _WSA_TCPCloseSocket
      _WSA_TCPConnect
      _WSA_TCPListen
      _WSA_TCPRecv
      _WSA_TCPSend

      #INTERNAL_FUNCTIONS
      __TimeoutManager
      __TimeoutReset

      #EXTRA_FUNCTIONS
      _WSA_GetAddrInfo
      _WSA_GetHostByAddr
      _WSAAsyncGetHostByName
      _WSAAsyncGetHostByName_Callback
      _WSA_GetNameInfo
       
      Requirements:
      - AutoIt Versions: 3.3.8.1 thru 3.3.15.0 (32Bit only).
      - TCPStartup() at beginning of script on startup.
      - TCPShutDown() and _WSA_Cleanup() on exit.
      Download UDF: WSA_NBTCP.au3
