Unicode code of an array

Recommended Posts

I made a small program that should get the unicode code of an array, save it in a variable, and write it into an file. That should be done for every array of a string.

For $i = 0 To $len Step 1           ; $len is the length of the text I enter previously

    $tmp0 = ChrW($text[$i])         ; $text is the text
    FileWrite($f, $tmp0 & @CRLF)    ; $f is the file I write into
    $tmp0 = ""

Next

Building and compiling finish without raising warnings or errors, but the program fails when it's supposed to get the unicode code of that array... 

The error message says "Line 357 (File "D:\documents\coding\Crypt\Crypt.exe"): Error: Subscript used on non-accessible variable."

My code ends at line 141, so it's not a problem with my code as such. I'd say that ChrW() isn't able to handle the variable I give it. I don't think it's a problem with the string, but I suspect that it's because I use a variable as an index ($text[$i]).

If my clue was right, how do I fix it? If not, what could be the problem? Thanks for the help!

I don't know where and how you declared and defined $len. I don't know what the contents of $text are.

My only guess, based on the small snippet of code you posted, is you did $len as the full length of the string but forgot to subtract 1 (since string lengths start at 1 unless the string is "")

Which data is assigned ´to $test? And also without any include the script has not 357 lines. May be you have to change to 

For $i = 0 To $len-1 ;Step 1 not nececary

if not post the complete script.

Local $len = StringLen($text)
Local $text = InputBox("UCC", "Enter the text")

$text is entered by the user, but it will be plain text like "abc" or "test" or "hello". Sometimes there might be numbers in there too, but really nothing special (yet).

I didn't know that, thanks. Unfortunately, neither subtracting 1 from $len, nor using $i = 1 in the for-loop works (same error).

Okay, here's the full script. Maybe you find the problem in there.

(before you tell me, yes, I know that this is probably the weakest encryption ever. It's just for learning autoit a bit better and hiding my personal notes from friends and family)

Crypt.au3

Edit: it's not fully finished yet, so please excuse some unnecessary things in there.

Func Encryption($log, $text, $file)

   Local $len = StringLen($text)
   Local $f = FileOpen($file, $FO_APPEND)
   Local $tmp0 = ""
   Local $tmp1 = ""
   Local $aText = StringSplit($text,'',2)

   For $i = 0 To UBound($aText)-1

      $tmp0 = ChrW($atext[$i])
      FileWrite($f, $tmp0 & @CRLF)
      $tmp0 = ""
      $tmp1 = ""

   Next

   FileWrite($log, "Text encrypted on " & @MDAY & "." & @MON & "." & @YEAR & " at " & @HOUR & ":" & @MIN & ":" & @SEC & @CRLF)
   FileClose($f)

EndFunc

Just making string $Text to a array and work with should be the solution. But this is not crypted, see there for

Easy task and much better as to decrypt boter's wishes. AutoIt is not the first programming langue? i think C or Pascal was first?

I indeed tried some other programming languages first :) I did C++, vbs and python before, but switched to autoit because it's enough for my basic needs and A LOT easier than C++ for example.

Idk about  A LOT easier than C++. What you're doing is very simple and pretty easy in C++ too. If all you're doing is some simple stuff for fun then AutoIt is fine. If you want to get into programming don't make AutoIt your go to. It's simple, easy, and the syntax is forgiving, but it's more of a supplement than a full course meal.

Python, I'm told, is a good beginner language, as is Java, and if you want to do something easy in .net than C# is another good one. C++ can be hard and difficult for a beginner but if you get a good book, and spend the time reading and understanding what it's trying to teach you, you will do fine. Also, classes and objects are like crack and a good IDE makes writing code so much better.

Just my two cents.

      I'm having some issues with writing to column C when an element is found. It works on C2 but it does not continue to C3, C4, C5, etc..... I'm wanting to write "test" if the element //input[@id='username'] is found  $someUser = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//input[@id='username']"). I have attached my HTML and Excel file along with my AutoIt code below:
      #Include "wd_core.au3" #Include "wd_helper.au3" #Include "wd_core.au3" #Include "File.au3" #Include "Array.au3" #Include "Excel.au3" Local $sDesiredCapabilities, $sSession _WD_Startup() $Ssession = _WD_CreateSession($sDesiredCapabilities) _WD_Navigate($sSession, "https://127.0.0.1/test.html") _WD_LoadWait($sSession) Local $oExcel = _Excel_Open() Local $oWorkbook = _Excel_BookOpen($oExcel, "C:\Users\<Username>\Downloads\test.xlsx") Local $aArrayTest1 = _Excel_RangeRead($oWorkbook, 1, $oWorkbook.ActiveSheet.Usedrange.Columns("A:A")) Local $aArrayTest2 = _Excel_RangeRead($oWorkbook, 1, $oWorkbook.ActiveSheet.Usedrange.Columns("B:B")) For $i = 0 To UBound($aArrayTest1) - 1 _WD_Navigate($Ssession, $aArrayTest1[$i]) _WD_LoadWait($sSession) $someUser = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//input[@id='username']") _WD_SetElementValue($sSession, $someUser, $aArrayTest2[$i]) Local $sElement = _WD_FindElement($sSession, $_WD_LOCATOR_ByXPath, "//input[@type='submit'][@value='Submit']") _WD_ElementAction($sSession, $sElement, 'click') _WD_LoadWait($sSession) Sleep(5000) If $someUser Then Local $aArray2D[2] = ["test"] _Excel_RangeWrite($oWorkbook, $oWorkbook.ActiveSheet, $aArray2D, "C2") EndIf Next Func SetupChrome() _WD_Option('Driver', 'chromedriver.exe') _WD_Option('Port', 9515) _WD_Option('DriverParams', '--log-path="' & @ScriptDir & '\chrome.log"') $sDesiredCapabilities = '{"capabilities": {"alwaysMatch": {"goog:chromeOptions": {"w3c": true, "args":["start-maximized","disable-infobars"]}}}}' EndFunc ;==>SetupChrome

      hello again,
      it has been a long time since i have been here and a long time since i last used autoit. ever so often when the time allows me to, then i follow up on an idea that i had a long time ago. i have done all the work on paper but now it is up to writing it in autoit and i keep stumbling over many little issues here and there. sometimes after a few days i will try again and get a step further but sometimes it just will not help no matter how long i try and think about a solution. for most of you it will be the basics but for me it is not all that easy, but at least i give it a try.
      right, down to business:
      here is my code:
      #include <MsgBoxConstants.au3> #include <StringConstants.au3> #include <Array.au3> #include <String.au3> ; ; PART 1: define replacements and check with msgbox ; Global $y, $z $y = "Yes" $z = "No" MsgBox(0,"replacements", $y & @CRLF & $z) ;the replacements in a message box ; ; PART 2: set the texts and check via console and msgbox ; Global $my1string = "abab" ;the first specified text MsgBox(0,"my1string", $my1string) ;the message box to output the first specified text Global $my2string = "icic" ;the second specified text MsgBox(0,"my2string", $my2string) ;the message box to output the second specified text ; ; PART 3: transform the strings to individual arrays ; $my1array = StringSplit($my1string, "") $my1array[0] = "" _ArrayDelete($my1array, 0) _ArrayDisplay($my1array, "my1array") ;the display of the first specified array $my2array = StringSplit($my2string, "") $my2array[0] = "" _ArrayDelete($my2array, 0) _ArrayDisplay($my2array, "my2array") ;the display of the first specified array ; ; PART 4: create an empty array for filling ; Global $OutputArray[4] $OutputArray[0] = "" _ArrayDisplay($OutputArray, "OutputArray") ;the display of the first specified array ; ; PART 5: compare & fill empty OutputArray with data after evaluation ; Global $i, $j, $k For $i = 0 to UBound($my1array) -1 For $j = 0 to UBound($my2array) -1 For $k = 0 to UBound($OutputArray) -1 If $my1array[$i] = "a" And $my2array[$j] = "i" Then $OutputArray[$k] = $y Else $OutputArray[$k] = $z EndIf Next Next Next _ArrayDisplay($OutputArray, "OutputArray") ;the display of the Newly filled Array In "Part 2" i make a string that is converted to an array in "Part 3" ... Now, I know that "a" and "i" are always in the exact same spot in both arrays and so i wanted to compare this and make a further array to document my findings by saying "yes" or "no" ... however my new array keeps saying just "no" allthough i can clearly see and know that it should say:
      yes no yes no my guess is that there is something wrong within my for-loops and that the counting is somehow "off" i guess that when the first for-loop is finished it reaches the second whilst the second for-loop is checking the first which would explain why it always says "no" instead of seeing the obvious.
      so my question would be: what is wrong with my for-loop? or where am i making an error that ultimately gives me the wrong results?
      help is much appreciated.
      kind regards
      roeselpi

      Hi dear friends!, i'm sorry for creating a new thread (a new problem), i have over than 9 lists that i want to combine them to be this (in this example, there are 3 test files):


      I've written a little code for splitting main information, but i really confused how to make results as "Output.txt", here is that code:
       
      $sRegex_1 = StringRegExp(FileRead("1.txt"), '(?s:(?<=\=\=\r\n)(.*?)(?=\r\n\=\=))', 3) $sRegex_2 = StringRegExp(FileRead("2.txt"), '(?s:(?<=\=\=\r\n)(.*?)(?=\r\n\=\=))', 3) $sRegex_3 = StringRegExp(FileRead("3.txt"), '(?s:(?<=\=\=\r\n)(.*?)(?=\r\n\=\=))', 3) For $i = 0 To UBound($sRegex_1) - 1 ConsoleWrite($sRegex_1[$i] & @CRLF) For $j = 0 To UBound($sRegex_2) - 1 ConsoleWrite($sRegex_2[$j] & @CRLF) For $k = 0 To UBound($sRegex_3) - 1 ConsoleWrite($sRegex_3[$k] & @CRLF) Next Next Next

      hello evrybody
      here is an example about how to split your texts using a delimiter with the ability to select how much of delimiters shows in each colum  with $i_number
      e.g
      you have a long text and you want to split it in an array
      that evry colum have a number (n) of lines
      i made a function that do that for you
      just call it with a three params
      $s_text
      your text
      $i_number
      the number that you want to put in each col
      $s_siparator
      the siparator
      default is "|"
      here is the function with example
      i hope that it will be useful for you
       
      ****
       
      #include <Array.au3> $s_txt = "some text1some text2|some text3|some text4|some text5|some text6" $array = splitText($s_txt, 2) _ArrayDisplay($array) Func splitText($s_text, $i_number, $s_siparator = "|") Local $a_TXT = StringSplit($s_text, $s_siparator) Local $a_Return[$a_TXT[0] + 1] If ($a_TXT[0] <= $i_number) Or ($i_number <= 0) Then ReDim $a_Return[2] $a_Return[0] = 1 $a_Return[1] = $s_text Return $a_Return EndIf Local $i_Processed = 1, $i_arrayProcessed = 1 Do For $i = $i_Processed To ($i_Processed + $i_number) - 1 If ($a_TXT[0] < $i) Then ExitLoop If Not ($a_Return[$i_arrayProcessed]) Then $a_Return[$i_arrayProcessed] = $a_TXT[$i] Else $a_Return[$i_arrayProcessed] &= $s_siparator & $a_TXT[$i] EndIf $i_Processed += 1 Next $i_arrayProcessed += 1 Until ($a_TXT[0] < $i_Processed) ReDim $a_Return[$i_arrayProcessed] $a_Return[0] = $i_arrayProcessed - 1 Return $a_Return EndFunc ;==>splitText
      accept my greetings
      thanks to
