Hello friends, I have a simple question, can I have a variable that is not reset, even if my program is closed?
That is, I want to make a program that can only be opened once, have a variable $ ini = 0, when it is opened for the first and only time it becomes $ ini = 1, so that it can not use the program a second time, as if it was a test software.
I do not want the variable to depend on a reading of an external file that is easily manipulated. Thank you.

Variables, by their nature, live while your program is alive. You cannot expect the computer to remember the variable setting between runs of your program unless you are writing it somewhere outside of memory (it is called volatile for a reason). That would be an INI file, a Registry entry, a DLL even, but somewhere on the physical drive.

If you do not want to use a file, go with a registry entry written on first run and then checked on subsequent runs.

supposing you are using a compiled script, here a simple 'experiment' to have a program runnable only once.
In few words, after the first run, I just append a byte at the end of the exe setted to "1" so at the next run we found the "1" as the last byte and we exit.
just a funny experiment, no claim of bullet-proofness...

If Not @Compiled Then Exit MsgBox(0, "Info", "script not compiled error.")
Local $sThis = @ScriptFullPath

Local $hHndl = FileOpen($sThis, 16) ; open the exe in byte mode
FileSetPos($hHndl, -1, 2) ; $FILE_END (2) -1 = last byte of the file
$LastByte = FileRead($hHndl, 1) ; get last byte

If $LastByte = "1" Or $LastByte = 0x31 Then
    MsgBox(0, "Debug " & $LastByte, "I'm sorry, this program has expired", 5)
    Exit
EndIf

; your one time run program here below
; ------------------------------------
MsgBox(0, "Debug " & $LastByte, "This is a 'one time only' run program" & @CRLF & "next time this program will not run")
;
;
; on exit add a byte to the exe to flag "no more run"
; ------------------------------------
; ping is just to wait 2 seconds so to give time to the main exe to terminate
; You can't write a byte to the exe if is running
Local $sCommand = 'ping localhost -n 2 > nul & echo | set /p dummy="1" >> ' & $sThis
; the command is run 'detached' from the main exe
Run(@ComSpec & " /c " & $sCommand) ; , @SW_HIDE)

removed the show_flag from the run command

hi @mikell

the last run command delegates the dos environment to execute the 2 concatenated commands in a detached way from the main script. The ping command is there as a sort of delay of about 2 seconds to give time to the main exe to terminate so that it is not locked when the second command will append the last byte to the exe.
However a weird fact happens.... if the show_flag parameter of the run command is set @sw_hide or @sw_minimize then the write of the byte fails.  I've seen that just removing the show_flag  parameter from the run command allows it to work.
...maybe the echo fails if command prompt is hidden...??
suggestions and alternatives to write a byte from dos environment to a file are welcome

Another way but NTFS-only. Kid sister will bypass this but most users won't.

#include <Date.au3>

If Not @Compiled Then Exit MsgBox(0, "Info", "Script must be compiled to run (once only).")

Local $sFname = @ScriptFullPath & ":Dead Beef"

If FileExists($sFname) Then
    MsgBox(0, "Run status", "Sorry this program has expired. It already ran on " & FileRead($sFname), 5)
    Exit
Else
    _Main()
EndIf

Func _Main()
    MsgBox(0, "Welcome", "This is a 'one time only' runable program" & @CRLF & "Next time this program will not run.")

    ; program core here

    FileWrite($sFname, _NowCalc())
EndFunc

As a colon is not allowed in windows inside a file name, what is happening there?

My example demonstrates a colon there is perfectly valid syntax.
The magic is named as @BrewManNH said an ADS (Alternate Data Stream).

No idea why I keep reversing those.

Thank you very much to all for your answers, I tell them how I did it, in the end I created a .log file, with information encrypted inside, where I give guidelines to the program of how many times it can be executed and also the limit of queries that can be made , I read them all and I'm going to try the things they told me to see how it goes. Thanks brothers. :ILA2:

      I have a autoit exe file which is used in upload/browse file functionality.  This has been integrated with selenium framework and I am invoking the autoit exe using Java process and runtime. 
      Now the issue is when I run the scripts and invoke the autoit exe in local it works perfectly.  But when I use selenium grid or jenkins to run the scripts in another windows server it is not working.
      Can anyone please suggest any solution for this?

      Hello, the script below will read column A from an excel file - and if a value matches in the browser, it will click the corresponding link and click on a specific button to paste the data, then writes "Completed" in Column B.

      What i am trying figure out now is if the excel crashes while the script/loop is running, I want to relaunch the excel file continue to the last row before the excel crashed. So if the value of column B is not marked as "completed", it should continue from that row
      Appreciate any help that I can get to achieve this.

      Hello ,
      I am trying to use Websockets in AutoIt.
      It is to fetch live stock market prices , API is provided and documentation available for python language.
      The link for the code snippet is :
      https://symphonyfintech.com/xts-market-data-front-end-api-v2/#tag/Introduction
      https://symphonyfintech.com/xts-market-data-front-end-api-v2/#tag/Instruments/paths/~1instruments~1subscription/post
       
      https://github.com/symphonyfintech/xts-pythonclient-api-sdk
       
      Second Link is to subscribe to a list of ExchangeInstruments.
      Now I would like to get live stock ltp (LastTradedPrice) for a few stocks whose "ExchangeInstrumentID" I know.
      I am able to use the WinHttp object to perform actions using simple codes like below :
      I have the secretKey and appkey and can generate the needed token. And get the unique ExchangeInstrumentID.

      Below code is just for example of how I am using WinHttp. Unrelated to socket part.
      Global $InteractiveAPItoken = IniRead(@ScriptDir & "\Config.ini", "token", "InteractiveAPItoken", "NA") $baseurl = "https://brokerlink.com/interactive/" $functionurl = "orders" $oHTTP = ObjCreate("winhttp.winhttprequest.5.1") $oHTTP.Open("POST", $baseurl & $functionurl, False) $oHTTP.SetRequestHeader("Content-Type", "application/json;charset=UTF-8") $oHTTP.SetRequestHeader("authorization", $InteractiveAPItoken) $pD = '{ "exchangeSegment": "NSEFO", "exchangeInstrumentID": ' & $exchangeInstrumentID & ', "productType": "' & $producttype & '", "orderType": "MARKET", "orderSide": "' & $orderside & '", "timeInForce": "DAY", "disclosedQuantity": 0, "orderQuantity": ' & $qty & ', "limitPrice": 0, "stopPrice": 0, "orderUniqueIdentifier": "' & $orderidentifier & '"}' $oHTTP.Send($pD) $oReceived = $oHTTP.ResponseText $oStatusCode = $oHTTP.Status
          
          
      But am struggling to understand and use socket.
      Would be of great help if you can have a look at the link mentioned above and help with the code sample for AutoIt.
      To connect and listen to a socket.
      Thanks a lot

      Hi, I have a site that has the following elements below: 
      <div>More element here</div> <div>More element here</div> <div>More element here</div> When I do this in Auto It:
      Local $oSelectDiv = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "div") _WD_HighlightElement($sSession, $oSelectDiv, 1) I also tried to add [3], but it doesnt seems to work:
      Local $oSelectDiv = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "div[3]") _WD_HighlightElement($sSession, $oSelectDiv, 1) It always highlight the first one, but I am trying to highlight the 3rd in the list. Is there anyway to select the 3rd div without having to add any class/id in the divs, and without using XPATH? The structure of the elements in that site were built that way.

      My au3 script program needs administrator privileges on win10 to be executed correctly, because it needs to be added to the boot---Script code:RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run", @ScriptName, "REG_SZ", @ScriptFullPath)
      I need to let the program automatically get administrator privileges, so I use a function of #RequireAdmin. Although the program can be added to the boot, but does not execute after system boot up? why is that?
      What should I do?
      --------------------------------------------------------------------
      Update:
      I found that after using the #RequireAdmin function, the program cannot be executed after system boot up.
      An example is given below. after it is compiled, it will not be executed after system boot up in the following two ways.
      1. C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp\
      2. RegWrite("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run", @ScriptName, "REG_SZ", @ScriptFullPath)
      why is that?
      example
      #include <MsgBoxConstants.au3>
      #RequireAdmin
      Func test()
          MsgBox(0, "", "this is test message")
      EndFunc   ;==>test
      test()
