  1. Version v1.1.2


    Purpose (from Microsoft's website) The HTTP Server API enables applications to communicate over HTTP without using Microsoft Internet Information Server (IIS). Applications can register to receive HTTP requests for particular URLs, receive HTTP requests, and send HTTP responses. The HTTP Server API includes SSL support so that applications can exchange data over secure HTTP connections without IIS. Description There have been several times in the past that I wanted to either retrieve information from one of my PCs or execute commands on one of my PCs, whether it was from across the world or sitting on my couch. Since AutoIt is one of my favorite tools for automating just about anything on my PC, I looked for ways to make to make it happen. Setting up a full blown IIS server seemed like overkill so I looked for lighter weight solutions. I though about creating my own AutoIt UDP or TCP server but that just wasn't robust enough, Then I found Microsoft's HTTP Server API and it looked very promising. After doing a little research into the APIs, I found that it was flexible & robust enough to handle just about any of the tasks that I required now and in the future. So a while back I decided to wrap the API functionality that I needed into an AutoIt UDF file to allow me to easily create the functionality I needed at the time. It has come in very handy over the years. Of course it wasn't all wrapped up with a nice little bow like it is now. That only happened when I decided to share it with anyone else who could use it or learn from it. The example file that I included is a very granular example of the steps required to get a lightweight HTTP Server up and listening for GET requests. The UDF is a wrapper for the Microsoft APIs. That means to do anything over and above what I show in the example, one would probably have to have at least a general knowledge of APIs or the ability to figure out which APIs/functions to use, what structures and data is needed to be passed to them, and in what order. However, the UDF gives a very solid foundation on which to build upon. Of course, if anyone has questions about the UDF or how to implement any particular functionality, I would probably help to the extent that I could or point you in the right direction so that you can figure out how to implement your own solution. The APIs included in the UDF are the ones that I needed in the past to do what I needed to do. If any additional APIs need to be added to the UDF file, please make those suggestions in the related forum topic. Being that this is basically an AutoIt wrapper for the Microsoft API functions, there's no need to create AutoIt-specific documentation. All of the UDF functions, structures, constants, and enumerations are named after their Microsoft API counterparts. Therefore, you can refer to Microsoft's extensive documentation of their HTTP Server API. As stated earlier, if there is one or more APIs that you find yourself needing for your particular solution, please suggest it in the related Example Scripts forum topic.

  2. Hi guys/girls! I'm gonna share this UDF I made today. It allows you to easily create TCP servers and set actions depending on three events: OnConnect, OnDisconnect and OnReceive. It is also multi client (you can set the clients limit) and you can also bind a Console-based executable to the socket (similar to -e parameter in NetCat). This feature is useful if you want to use some Console UDF to create your TCP server and don't want to mix it with the TCP functions. Also, as it runs on background just firing events, it won't pause your script while listening/receiving, so you can do anything else (stop and restart the server, allow the user to click buttons or just wait on an infinite loop) that your callbacks will be called once the event is fired. It's also very easy to use. See this examples: Example #1: A basic server By running this (then connecting to the server using Netcat), you will receive a message box telling you when some user connects or disconnects (the socket ID and his IP address is passed as parameter to your callback function) and also when the user sends something over the TCP socket (the data sent is passed as parameter). #cs Download netcat at https://eternallybored.org/misc/netcat/ Execute this script Run in CMD: nc -vv 8081 #ce #include "TCPServer.au3" ; First we set the callback functions for the three events (none of them is mandatory) _TCPServer_OnConnect("connected") _TCPServer_OnDisconnect("disconnect") _TCPServer_OnReceive("received") ; And some parameters _TCPServer_DebugMode(True) _TCPServer_SetMaxClients(10) ; Finally we start the server at port 8081 at any interface _TCPServer_Start(8081) Func connected($iSocket, $sIP) MsgBox(0, "Client connected", "Client " & $sIP & " connected!") _TCPServer_Broadcast('new client connected guys', $iSocket) _TCPServer_Send($iSocket, "Hey! Write something ;)" & @CRLF) _TCPServer_SetParam($iSocket, "will write") EndFunc ;==>connected Func disconnect($iSocket, $sIP) MsgBox(0, "Client disconnected", "Client " & $sIP & " disconnected from socket " & $iSocket) EndFunc ;==>disconnect Func received($iSocket, $sIP, $sData, $sPar) MsgBox(0, "Data received from " & $sIP, $sData & @CRLF & "Parameter: " & $sPar) _TCPServer_Send($iSocket, "You wrote: " & $sData) _TCPServer_SetParam($iSocket, 'will write again') EndFunc ;==>received While 1 Sleep(100) WEnd Example #2: A basic HTTP server (just one page, as it is just an example) In this example, we run this code and point our browser to the address mentioned on the comments. A basic "It works!" page is show. #cs Run this script Point your browser to http://localhost:8081/ #ce #include "TCPServer.au3" _TCPServer_OnReceive("received") _TCPServer_DebugMode(True) _TCPServer_SetMaxClients(10) _TCPServer_Start(8081) Func received($iSocket, $sIP, $sData, $sParam) _TCPServer_Send($iSocket, "HTTP/1.0 200 OK" & @CRLF & _ "Content-Type: text/html" & @CRLF & @CRLF & _ "<h1>It works!</h1>" & @CRLF & _ "<p>This is the default web page for this server.</p>" & @CRLF & _ "<p>However this server is just a 26-lines example.</p>") _TCPServer_Close($iSocket) EndFunc ;==>received While 1 Sleep(100) WEnd Example #3: A telnet-like server (Command Prompt bound to the socket after password requesting) By running this example and connecting with Netcat, we will be asked for a password, which is 12345 as we set on the script. If the password is correct, we will see the Command Prompt live-updated (try running a ping to some server, for example). #cs Download netcat at https://eternallybored.org/misc/netcat/ Execute this script Run in CMD: nc -vv 8081 #ce #include "TCPServer.au3" Global $sPassword = "12345" ; input server password here _TCPServer_OnConnect("connected") _TCPServer_OnDisconnect("disconnect") _TCPServer_OnReceive("received") _TCPServer_DebugMode(True) _TCPServer_SetMaxClients(10) _TCPServer_Start(8081) Func connected($iSocket, $sIP) _TCPServer_Send($iSocket, "Welcome! Please input password: ") _TCPServer_SetParam($iSocket, 'login') EndFunc ;==>connected Func disconnect($iSocket, $sIP) MsgBox(0, "Client disconnected", "Client " & $sIP & " disconnected from socket " & $iSocket) EndFunc ;==>disconnect Func received($iSocket, $sIP, $sData, $sParam) If $sParam = "login" Then If $sData <> $sPassword Then _TCPServer_Send($iSocket, "Wrong password. Try again: ") Return Else _TCPServer_SetParam($iSocket, 'command') _TCPServer_BindAppToSocket($iSocket, 'cmd.exe') EndIf ElseIf $sParam = "command" Then _TCPServer_SendToBound($iSocket, $sData) EndIf EndFunc ;==>received While 1 Sleep(100) WEnd The limit is your imagination? Well, no sure. We have this limit: You can't create more than one server with this UDF in the same script. However, you can pause and resume (read 'stop and start again') your server at any time in your script, without having to reset the server settings. And of course you can have many clients (or just one, it's your choice!) in the same server. Or run multiple instances.Functions list: _TCPServer_Start _TCPServer_Stop _TCPServer_Close _TCPServer_Send _TCPServer_Broadcast _TCPServer_SetParam _TCPServer_BindAppToSocket _TCPServer_SendToBound _TCPServer_UnBindAppToSocket _TCPServer_GetMaxClients _TCPServer_IsServerActive _TCPServer_ListClients _TCPServer_OnConnect _TCPServer_OnDisconnect _TCPServer_OnReceive _TCPServer_SetMaxClients _TCPServer_DebugMode _TCPServer_AutoTrim _TCPServer_SocketToIP _TCPServer_SocketToConnID _TCPServer_ConnIDToSocket Help file and more examples included!

  3. Hello Guys and AutoIt Scriptwriters!🎉❤️ I've created a script to notify to me if RDP main IP changed then send a message via Telegram bot to me But some of my RDP's Main IP are @IPAddress1 or @IPAddress3 or Public IP Address... I want to detect automatically the IP that windows client can run RDP to remotely control This image can help you that what i say, there are three RDP with specified IP, i want to run script in these RDP's then capture those IP's changes then notify me via Telegram bot

  5. Hi everyone, I wonder if there is a cloud service that can offer a physical server so that AutoIT can turn as it is in a physical machine. Thank you
  6. Here I am again, with a brand new UDF! (not so new through...) Taking (great) advantage of the new maps feature, I made a simple, flexible multi-clients TCP server UDF. Features: You can create multiples servers in one scriptPeers limit is optional (the real peers limit is your RAM and the maps performances)You can configure max data receive len (2nd argument of TCPRecv) on a per-client basisYou can set an optional idle time-out (time without receiving any data before peer gets disconnected)Each peer has an empty Map that can contain user defined dataYou can set a function that will be called for each connected peer at pre-defined interval (onPeerCycle callback)The UDF is callback driven (onConnect, onDisconnect, onReceive, onError, onPeerCycle)You can set a disconnect message when kicking a peer. This message will be passed to the onDisconnect callbackonReceive callback must return the number of bytes that have been consumed. Say you receive 100 bytes of data but you used (consumed) only 70 bytes, by returning 70 from the callback the remaining 30 bytes will be buffered and passed again on the next call to onReceiveKnown bugs: TCPRecv bug! the function doesn't detect peer disconnection (hope this will be fixed soon)Download: https://github.com/matwachich/generic-tcp-server/ Thanks in advance for your feedback!
  7. Folks, I have an issue I've been trying to solve for a while, I'm trying to add static routes in DHCP via a 121 route rule in Windows 2012 R2 is a brutal manual process and wanted to automate this via AutoIT. When I use the "ControlGetText" everything displays properly in the MSG box but when I try and use "ControlSetText" or "ControlSend" the values won't display in the input box but the action comes back as successful? Anyone able to help me with this? I'm thinking this might be an active window issue but i'm not sure. Here is a part of my code. $hWnd = WinWait("[TITLE:Add a Static Route]","", 10) WinActivate($hWnd) $Status = ControlSend($hWnd, "", "[CLASS:Edit; INSTANCE:4]", "192"); Does not add 192 to the text box. Local $sTextEdit1 = ControlGetText($hWnd, "", "[CLASS:Edit; INSTANCE:1]") ConsoleWrite ( "ControlSend Status: " & $Status & @CRLF); Returns a Value of 1 ConsoleWrite ( "ControlGetText Value Edit1: " & $sTextEdit1 & @CRLF); Please see attachment for more info.
  8. I have a button control as below screen. This one I am able to suppress using below code in all the OS. But on server 2008, sometimes the button highlighted in the image is not getting clicked and some times it is working. I have cross checked the IDs when it is not working, but it is working only. $win1 = "erwin Mart Configuration" $MartConfigWindow = _WinWaitActivate1($win1,"Database Details") ControlSetText($MartConfigWindow, "", "WindowsForms10.EDIT.app.0.378734a6", $dbserver) ControlSetText($MartConfigWindow, "", "WindowsForms10.EDIT.app.0.378734a4", $dbname) ControlSetText($MartConfigWindow, "", "WindowsForms10.EDIT.app.0.378734a9", $dbuser) ControlSetText($MartConfigWindow, "", "WindowsForms10.EDIT.app.0.378734a8", $dbpassword) ;Button clicl logic $iControlClickStatus = ControlClick($MartConfigWindow, "", "[CLASS:WindowsForms10.BUTTON.app.0.378734a; INSTANCE:2]") ;If above button click fails, trying with mouse click on the control if ControlFocus($MartConfigWindow, "", "WindowsForms10.BUTTON.app.0.378734a2")=1 then ;sometimes above button fails in win server 2008,so this loop Send("{ENTER") EndIf Any suggestion on how to resolve this.?
  9. Hi! If you liked my TCPServer UDF, you'll also like this one. Following the same principles, this TCPClient UDF helps you on handling multiple connections to different servers, and set actions depending on two events: OnReceive and OnDisconnect. It is also multi server (you can connect to many servers at once) and you can also bind a Console-based executable to the socket (similar to -e parameter in NetCat). This feature is useful if you want to use some Console UDF to create a TCP application and don't want to deal with the TCP* functions. Also, it runs on background just firing events, it won't pause your script while waiting/receiving data, so you can do anything else (close and open connections, allow the user to click buttons or just wait on an infinite loop) that your callbacks will be called once the event is fired It is also very easy to use. See this examples: Example #1: Connecting to a basic server By running this (as soon as you open a basic server with Netcat) you will receive a message box telling you when the server closes the connection (the socket ID and his IP address are passed as parameter to your callback function) and also when the server sends something over the TCP socket (the data sent is passed as parameter). #cs Download netcat at https://eternallybored.org/misc/netcat/ Execute this script Run in CMD: nc -vv -l -p 8081 #ce #include "TCPClient.au3" ; First we set the callback functions for the two events (none of them is mandatory) _TCPClient_OnDisconnect("disconnect") _TCPClient_OnReceive("received") ; And a parameter _TCPClient_DebugMode(True) ; Finally we connect to the server at port 8081 at any interface _TCPClient_Connect('', 8081) Func disconnect($iSocket, $sIP) MsgBox(0, "Server disconnected", "Server " & $sIP & " disconnected from socket " & $iSocket) EndFunc ;==>disconnect Func received($iSocket, $sIP, $sData, $sPar) MsgBox(0, "Data received from " & $sIP, $sData & @CRLF & "Parameter: " & $sPar) _TCPClient_Send($iSocket, "You wrote: " & $sData) _TCPClient_SetParam($iSocket, 'will write again') EndFunc ;==>received While 1 Sleep(100) WEndExample #2: Requesting a page from a HTTP server In this example, we run this code and it will get the response from a HTTP server. Of course, as we are requesting google.com index, it may just show a redirect page to a local (with country top-level domain) Google page or with some stuff on the URL. #include "TCPClient.au3" _TCPClient_OnReceive("received") _TCPClient_DebugMode(True) $iSocket = _TCPClient_Connect(TCPNameToIP('google.com'), 80) If @error Then Exit _TCPClient_Send($iSocket, "GET / HTTP/1.0" & @CRLF & @CRLF) Func received($iSocket, $sIP, $sData, $sParam) MsgBox(0, "Data received", $sData) _TCPClient_Disconnect($iSocket) EndFunc ;==>received While 1 Sleep(100) WEndExample #3: Command prompt bound to the socket after password requesting By running this example, we will be asked for a password, which is 123456 as we set on the script. If the password is correct, we will see the Command Prompt live-updated (try running a ping to some server, for example). #include "TCPClient.au3" #cs To test this example, execute a netcat server, running this commands: nc -vv -l -p 31337 #ce Global $Password = "123456" _TCPClient_OnReceive("receive") _TCPClient_OnDisconnect("disconnect") _TCPClient_DebugMode() Func receive($iSocket, $sIP, $sData, $mPar) If $mPar = "login" Then If $sData = $Password Then ; right password, let's change the parameter _TCPClient_SetParam($iSocket, "logged") ; and now bind _TCPClient_BindAppToSocket($iSocket, "cmd.exe") Else _TCPClient_Send($iSocket, "Wrong password. Try again: ") EndIf Else If $sData = "exit" Then ; unbinds _TCPClient_UnBindAppToSocket($iSocket) ; says bye _TCPClient_Send($iSocket, "See you") ; closes connection _TCPClient_Disconnect($iSocket) Else ; sends command directly to the process _TCPClient_SendToBound($iSocket, $sData) EndIf EndIf EndFunc Func disconnect($iSocket, $sIP) MsgBox(0, $iSocket, $sIP) EndFunc $iSocket = _TCPClient_Connect('', '31337') If @error Then MsgBox(0, "", "could not connect. Error: " & @error) Exit EndIf ; Sets parameter to login, so we know what the server is doing _TCPClient_SetParam($iSocket, "login") _TCPClient_Send($iSocket, "Please enter password: ") While True Sleep(100) WEndThe limit is your imagination?

  10. i am trying to figure out how a server can connect to a client Over the internet. In this is script. The client connects to the server on the same machine (localhost) and executes the commands from the client. How can I change that instead communicating over localhost to communicate over the internet with tcp ipaddress and a port. What i actually need help of is 1. The server will open a port and listen to communication from a No-ip address 2. I input the no-ip address and correct port in the client side, and when i click on connect, it connects to the server if its online This is the client #include <GuiConstantsEx.au3> THIS IS THE CLIENT #include <NamedPipes.au3> #include <StaticConstants.au3> #include <WinAPI.au3> #include <WindowsConstants.au3> ;

  11. I've ported these two functions from PHP to AU3 to work with URLs. Made them for those who work with libraries like HTTP.au3 (not the one I coded), that needs passing the server domain, path, etc., instead of the full URL. Grab the lib here. ParseURL( $sURL ) Parses the URL and splits it into defined parts. Returns an array: [0] = Full URL (same as $sURL) [1] = Protocol (i.e.: http, https, ftp, ws...) [2] = Domain [3] = Port (or null if not specified) [4] = Path (or null if not specified) [5] = Query string (everything after the ? - or null if not specified) Example: $aExample = ParseURL("https://google.com:8080/?name=doe") MsgBox(0, "Test", "URL: " & $aExample[0] & @CRLF & _ "Protocol: " & $aExample[1] & @CRLF & _ "Domain: " & $aExample[2] & @CRLF & _ "Port: " & $aExample[3] & @CRLF & _ "Path: " & $aExample[4] & @CRLF & _ "Query string: " & $aExample[5]) ParseStr( $sStr ) Parses a query string (similar to the [5] of the previous function) and returns a multidimensional array, where: [0][0] = number of variables found [0][1] = ununsed [1][0] = key name of the first variable [1][1] = first variable value (already URL decoded) [n][0] = key name of the nth variable [n][1] = nth variable value (already URL decoded) Example: include <Array.au3> ; need only to do _ArrayDisplay, not needed by the lib _ArrayDisplay(ParseStr("foo=bar&test=lol%20123")) #cs Result is: [0][0] = 2 [0][1] = ununsed [1][0] = foo [1][1] = bar [2][0] = test [2][1] = lol 123 #ce Feel free to fork!
  12. This topic will contain simple and working client server communication example along with some basic info for understanding. Examples are based on multi client communication that is happening on one computer (localhost). Changing (if it's not already set correctly) the IP address parameter on server script to reflect your network device IP address will allow you to communicate with other clients on network or even to communicate on internet if your network settings (forwarded router port, ip address on that port is seen from others on internet, you're not trying to do client server from identical computer on identical internet connection) are configured correctly. Every client connecting will need to have server IP address for network (or server public IP address for internet) connection in his client script. So edit client script to correspond to server address TCPConnect('type server ip address in client', 1018). Sometimes firewall can be your problem, if something isn't working turn off firewall and see if it helps. Server will always listen on his Network Adapter IP Address and not on his public address. In some rare occasions server can be set to listen on, with that he will listen from any device that he have physically connected on his MB USB or something third (with localhost included for listening). But i would not know the end result of what will happen if some other program that you have installed need that port (or you started 2 servers that interpret one with another). First part will hold just plain code.Second part will hold identical code with comments below commands for more info and understanding hopefully to help new autoit users to understand what and why that something is there.Other parts will hold additional info.First part: Working Code (working in two way communication, with multiple and-or identical client)Server #include <Array.au3> TCPStartup() Dim $Socket_Data[1] $Socket_Data[0] = 0 $Listen = TCPListen(@IPAddress1, 1018, 500) If @error Then ConsoleWrite('!--> TCPListen error number ( ' & @error & ' ), look in the help file (on MSDN link) on func TCPListen to get more info about this error.' & @CRLF) Exit EndIf While 1 For $x = $Socket_Data[0] To 1 Step -1 $Recv = TCPRecv($Socket_Data[$x], 1000000) If $Recv Then MsgBox(0, 'Client Number ' & $x & ' with connected socket identifier ' & $Socket_Data[$x], 'Recived msg from Client: ' & @CRLF & $Recv, 5) TCPSend($Socket_Data[$x], 'bye') TCPCloseSocket($Socket_Data[$x]) _ArrayDelete($Socket_Data, $x) $Socket_Data[0] -= 1 EndIf Next _Accept() WEnd Func _Accept() Local $Accept = TCPAccept($Listen) If $Accept <> -1 Then _ArrayAdd($Socket_Data, $Accept) $Socket_Data[0] += 1 EndIf EndFunc ;==>_AcceptClient TCPStartup() $Socket = TCPConnect(@IPAddress1, 1018) If @error Then ConsoleWrite('!--> TCPConnect error number ( ' & @error & ' ), look in the help file (on MSDN link) on func TCPConnect to get more info about this error.' & @CRLF) Exit EndIf TCPSend($Socket, 'Hi there.

Sixth Part: How to forward ports? (2 nice youtube tutorials) Seventh Part: Internet communication? If i wrote something incorrectly or wrong please tell me so that i can correct it. Edited: Local and Global, added aditional info about reciving msgs for maxlen buffer.

  14. Hello, I just made another TCP server. I will use the server for data collection and a lot of clients can get the data from TCP. I now use it for UDP broadcast some devices to get their IP's. You can also use it for chat's. It is very low level, but so you have more options than with the pure AutoIt functions. Just start the server in SciTE to see the console outputs. Then you can start up to 63 clients to talk to the server. I hope you like it.

  16. I am working on a desktop remote application so I made a simple server and client to send binary screen captures from client to server. All it's good if I test both scripts on my computer but when the client is in other network many screen shots are corrupted and some of them looks good. Have any idea why?

  18. First the Situation: I'm trying to automate an image uploading utility which lives on the client side of some cloud based server/client software and which was not designed to be automated. I've got a 2012 R2 VM running with autologon enabled on a local account. The account with autologon enabled has a scheduled task set up to run at 4AM daily. This task merely runs my AutoIt script. Now the issue: If I remote into my VM and run the script manually, it runs perfectly. If I edit my scheduled task to run only a few minutes in the future, and then reboot the VM, it also works perfectly. If I leave it to run overnight, the script starts but never finishes. It seems to be getting hung up waiting for the first window to become active. I've tried many version of the script now with no luck. The latest version is below. #include <File.au3> Dim $un = "username" Dim $pw = "password" ; Login window Run("C:\Program Files (x86)\CSI Software\Spectrum NG\Spectrum NG Client\SNGImageUploader.exe") Dim $hLogin = WinWait("[CLASS:WindowsForms10.Window.8.app.0.2bf8098_r11_ad1]", "Version: ") SendKeepActive($hLogin) WinActivate($hLogin) Send($un & "{TAB}" & $pw & "{ENTER}") SendKeepActive("") ; Main window - 1/3 Dim $hMain = WinWaitActive("SNG Image Uploader") SendKeepActive($hMain) Send("{TAB}{ENTER}") SendKeepActive("") ; File browser window Dim $hBrowse = WinWaitActive("Browse For Folder") SendKeepActive($hBrowse) Send("{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{RIGHT}{DOWN}") Sleep(2000) ; Give the program moment to detect images in the directory Send("{ENTER}") SendKeepActive("") ; Main window - 2/3 SendKeepActive($hMain) WinWaitActive($hMain) Send("{TAB}{ENTER}") SendKeepActive("") ; Upload complete window Dim $hUpload = WinWaitActive("[CLASS:#32770]", "Upload complete.

SendKeepActive($hUpload) Send("{ENTER}") SendKeepActive("") ; Import complete window Dim $hImport = WinWaitActive("[CLASS:#32770]", "Image import completed.

  19. Hi All, Written a script but need to make sure users don't run it on any of our Terminal Servers. So far I've added this as a work-around based on a naming convention, but I'd like to find a more robust way of checking: If Not StringInStr (@ComputerName, "ABCSydTS") Then ...Thanks!

    UDF for serializing and unserializing data. Serializing is converting any data to an easily storable format (you can convert an array to a string to save in a database, then convert it back to array).
  21. Morning all, For past few days I've been rattling my brains trying to work out how to create TCP Server and Client. I have successfully made a connection between a single client and server but beyond that I'm hopeless! I've been messing with Arrays and trying to read other examples but it's a little over my head... I was hoping I could ask someone to give me a really simple example with some comments for a server to accept multiple connections and a client to connect and receive data from server. I'm planning to have a client and server GUI to display "Client connected with identifier" "Server connected" "Message from server" etc Thanks in advance!
  22. Hi folks! I bring this little executable file and an AutoIt wrapper for it to generate documents (bills and incomes) by sending variables (strings, numbers or even arrays) to a PHP script you wrote. This is the syntax: themecli.exe <input> <output> <vars> input: The input PHP file (the extension does not need to be .php, it can be anything, like .html, .txt, .bin, .wtf...), relative to @ScriptDiroutput: The output HTML file to save, relative to @ScriptDirvars: A base64-encoded JSON with all the variables (hard? Don't worry! See below:)Looks confusing? Well, don't worry. That's why we have a wrapper! Example, if we have this file "page.php": Hello, <?=$user?>! How are you?And do this with AutoIt (using my JSONgen UDF [ http://www.autoitscript.com/forum/index.php?showtopic=173797 ] which is already included in AutoPHP): #include 'inc\autophp.au3' $ojson = New_JSON() JSON_AddElement($ojson, 'user', 'John Doe') $json = JSON_GetJSON($ojson) AutoPHP('page.php', 'hello.txt', $json)Note that you don't need to base64-encode it. After running it, we will see a file named "hello.txt", and the content is: Hello, John Doe! How are you?On the PHP file you can also use loops and everything else supported in PHP4 (since it uses Bambalam PHP Compiler, it does not support PHP5 yet). On the zip file there is an example of how to use it with loops.

  23. Good morning, I'm hoping some of you kind people could help me get started on a simple client on a workstation which can report events and computer information back to a console on a server to display all the information. I support primary schools which are always a mess when I take them on so this would be hugely helpful. I'm still very new to AutoIT so if anyone could point me in the right direction or any examples they have would be great. I did have a quick look on the forum but the topics I found looked way more complex for my needs. Thanks
  24. This may be a dumb question but ... I am currently using the ">Smtp Mailer That Supports Html And Attachments" by Jos (thank you Jos - cool script) to send emails from my script. I am trying to ensure that a copy of the sent email gets saved to the server so you can see it in the sent folder. I am using an account hosted by 1and1 for the email but am not on their Exchange server. A copy does get saved to the sent folder when I do it from my phone. The phone uses SSL (as does the script). The only difference (and I assume it is important) is the phone uses port 587 for SMTP. This port is refused by the script which, as a result, uses 465 instead to send. Is there any way to use that port 587 from the script? Alternatively, is there something else I should be doing? Any help would be appreciated. Happy holidays, JFish
  25. I've had this thing I wrote up laying around for a while now and decided I'd comment the heck out of it and post it here for others to enjoy as well. It's a multi-client TCP server "base" that has all the boilerplate code done, the only thing that one needs to do is just whip their protocol code in to it and it's ready to go. I've included a little few-line example bit in it (in the #region stuff) for a simple echo server. A quick way to see the example work is to just start this up and use a telnet client to connect to it on the port that you chose to have it bind (default in the one I'm posting is port 8080), typing a sentence, and pressing enter. This server makes use of setting the TCPTimeout option to 0, making it quite efficient when a high number of clients are connected and making it faster at accepting new connections. It does not use a fixed-size array for storing client connections, but instead dynamically re-sizes the client array when clients disconnect or connect (Setting $MaxClients to 0 makes the number of simultaneous clients only limited by RAM or AutoIt internal limits, whatever is reached first. I've tested this at 10,000 concurrent connections successfully, albeit with some slightly elevated CPU usage ). The server also implements a simple per-client packet buffer (as shown in the little echo example) which can come in handy for things such as large packets from file transferring and such. Instead of only relying on checking @error after a TCPRecv call to determine if a client disconnected (which can lie in certain cases), this uses a checking function which implements both that @error check and an idle timeout check that disconnects the client if they have not sent anything in a certain period of time. This is not really aimed at people who are unfamiliar with sockets work in AutoIt, as this provides no real application layer protocol, you must make that yourself. The only thing this does is do all the hard and/or tedious work of managing what happens when clients try connecting, how packet data should be buffered, and when a connection should be considered "dead". If you use this in a project, a simple little comment saying you used it would be nice #cs ---------------------------------------------------------------------------- AutoIt Version: (Or greater) Author: Ken Piper Script Function: Template multi-client server base code. Use as a base for making an efficient server program. This base will just accept connections and echo back what it receives, and kill the connection if it is dead or inactive for x seconds. It will not do any other work, that must be added seperately! #ce ---------------------------------------------------------------------------- TCPStartup() Opt("TCPTimeout", 0) #region ;Safe-to-edit things are below Global $BindIP = "" ;Listen on all addresses Global $BindPort = 8080 ;Listen on port 8080 Global $Timeout = 15000 ;Max idle time is 15 seconds before calling a connection "dead" Global $PacketSize = 2048 ;Max packet size per-check is 2KB Global $MaxClients = 50 ;Max simultaneous clients is 50 #endregion ;Stuff you shouldn't touch is below Global $Listen Global $Clients[1][4] ;[Index][Socket, IP, Timestamp, Buffer] Global $Ws2_32 = DllOpen("Ws2_32.dll") ;Open Ws2_32.dll, it might get used a lot Global $NTDLL = DllOpen("ntdll.dll") ;Open ntdll.dll, it WILL get used a lot Global $CleanupTimer = TimerInit() ;This is used to time when things should be cleaned up OnAutoItExitRegister("Close") ;Register this function to be called if the server needs to exit $Clients[0][0] = 0 $Listen = TCPListen($BindIP, $BindPort, $MaxClients) ;Start listening on the given IP/port If @error Then Exit 1 ;Exit with return code 1 if something was already bound to that IP and port While 1 USleep(5000, $NTDLL) ;This is needed because TCPTimeout is disabled.

Changelog: Cleared up formatting a bit in the [autoit] tags Fixed a bug in how it cleaned up the connection, and fixed a spelling error in the post Fixed a very rare corner-case that could cause a crash when getting many connections and disconnections in a short amount of time Changed a bit of code to fix issues with reading multiple buffered packets Fixed some spelling in the post and clean the code a bit; I try to keep this code up-to-date with the source file on my computer Fixed to add a massive performance increase when handling large numbers of connected clients and the client array needs to be trimmed. (I've seen up to a 500x speed increase on my computer!) Quick fix, apparently I forgot to set the max pending connections in TCPListen, leading for some pretty slow connection-accepting! Sorry about that. Fixed the problem of the latest AutoIt version causing "If @error Then" type statements to fail for TCPRecv, as TCPRecv now sets @error to -1 if the socket is alive but idle. This fixes the problem of clients getting instantly disconnected, sorry about not updating the code here with this sooner.
