Creating a function

Recommended Posts

bahjat

So i am trying to make a function out of many functions (i believe it is called recursion, read a post about it earlier on this forum)

When i try to make a number of things into 1 big function so i can call upon it later it doesn't seem to be working but when i take away the "func _hello()" and the "endfunc" from the end, everything seems to be working fine. Can someone please explain this to me. I know the problem is occurring because of the the "Conversion" function but i can't seem to understand why this is happening. Please help 

;;;****Program adds spaces *****
;;;***** the input variable here is $New*****
Global $final
Global $Hexadec
Func _hello()

$DataToBeDecrypted = "55fdaf fdafd"

$2space = $DataToBeDecrypted
$New = $2space

$AddingSpace = StringSplit($New, "")

$Final = ""

If Conversion($AddingSpace[0]) Then

    For $Spacing = 1 to $AddingSpace[0] Step 2
        $Final = $Final & $AddingSpace[$Spacing] & $AddingSpace[$Spacing+1] & " "
    Next

    MsgBox(0, "Adding space to the message so it can be converted back to Hex", $Final)

Else
    MsgBox(0, "Result", "String does not contain an even number of characters.")
EndIf

Func Conversion($Hexadec)
    Return Mod($Hexadec, 2) = 0
EndFunc
;;;***The final value is stored in the $final variable****


;***** Hexadecimals to ASCII*****
;;***Input variable is $HexadecimaltoASCII2******

$HexadecimalToASCII2 =$final
$HexadecimalsToASCII = ChrH($HexadecimalToASCII2)
$Ascii2Hex = Sub($HexadecimalsToASCII)
$v5ar = Chr($HexadecimalsToASCII);char

MsgBox(0,"Hex to ASCII",$HexadecimalsToASCII)

Func ChrH($v8)

    Local $v5=""
    $A1 = StringSplit($v8, " ")
    For $count = 1 To $A1[0]
        $v5 &= Chr(Dec($A1[$count]))
    Next
    Return $v5
endFunc


Func Sub($v8)

    Local $v9=""
    For $count = 1 To StringLen($v8)
        If StringLen(Hex(Asc(StringMid($v8, $count, 1)),2)) = 1 Then
            $v9 &=  "0" & Hex(Asc(StringMid($v8, $count, 1)))
        Else
            $v9 &=  Hex(Asc(StringMid($v8, $count, 1)),2)
        EndIf
        If $count <> StringLen($v8) Then $v9 &=  " "
    Next
    Return $v9
endFunc

;*****HEXADECIMAL to ASCII*****

EndFunc

Your code is incorrect because a function cannot be inside another function. You can of course have multiple functions calling each other.

And it's not recursion... Recursion means a function (or a child of it) calls itself. Like this:

_test()

Exit

Func _test()

    MsgBox(0, 0, "Calculating '5!' (5 permutation, i.e. 5*4*3*2*1)")

    $answer = _recursivePermutationCalculator(5)

    MsgBox(0, 0, $answer)
EndFunc   ;==>_test

Func _recursivePermutationCalculator($i)
    ; Now *this* is a recursive function, because it calls itself.
    If $i = 1 Then
        ; Because a function is not allowed to be infinitely recursive
        ; (which we don't want anyway, as we need an answer to the math problem),
        ; we need an exit condition.
        Return 1
    Else
        ; We'll add our current input $i to the permutation of $i - 1
        ; ($i)! = ($i) * ($i - 1)!
        Return $i * _recursivePermutationCalculator($i - 1) ; <-- function calling itself!
    EndIf
EndFunc   ;==>_recursivePermutationCalculator

I would like to say a big thank you, to you! That program you gave as an example was actually really helpful, much appreciated buddy. I also have another issue, do you think you can help me out on that too?

      Good evening everyone
      I was trying to insert function header to the functions of my script, but, in the SciTE console, this appears:
      Function or struct definition not found, unable to insert header. @Jos Any suggestion?
      Thanks in advance.

      Best Regards.

      Hi! I have another problem with AutoIT.  You see, I'm still the one who's just starting out with this great programming language. I have a problem with AutoIT, it seems not to recognize the "StringReplace" function even when it is by default. The code was made half in KODA and half of my own. It is a software programmed for the Italian language (I am Italian) and translate the SMS language into Italian correct. Would you help me? Thanks in advance.
       
      #include <ButtonConstants.au3> #include <EditConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> $hull = "hello" StringReplace($hull, "hello", "hellx") $Form1 = GUICreate("Linguaggio SMS A Italiano", 507, 498, 192, 124) $Edit1 = GUICtrlCreateEdit("", 24, 40, 465, 177) GUICtrlSetData(-1, "") $Label1 = GUICtrlCreateLabel("Inserisci qui il testo che non riesci a capire:", 24, 8, 205, 17) $Label2 = GUICtrlCreateLabel("Ecco il testo tradotto(non toccare questo campo):", 27, 237, 237, 17) $Edit2 = GUICtrlCreateEdit("", 24, 264, 465, 137) GUICtrlSetData(-1, "") $Button1 = GUICtrlCreateButton("Traduci", 104, 424, 249, 49) GUISetState(@SW_SHOW) While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit Case $Button1 StringReplace(GUICtrlGetData($Label1), "qlc", "qualcuno") StringReplace(GUICtrlGetData($Label1), "qls", "qualcosa") StringReplace(GUICtrlGetData($Label1), "ke", "che") StringReplace(GUICtrlGetData($Label1), "x", "per") StringReplace(GUICtrlGetData($Label1), "pls", "per favore") StringReplace(GUICtrlGetData($Label1), "tu6", "tu sei") StringReplace(GUICtrlGetData($Label1), "zzz", "mi fai dormire") StringReplace(GUICtrlGetData($Label1), "hagn", "Buonanotte") StringReplace(GUICtrlGetData($Label1), "tvtb", "Ti voglio tanto bene") StringReplace(GUICtrlGetData($Label1), "tat", "Ti amo tanto") StringReplace(GUICtrlGetData($Label1), "lafs", "Amore a prima vista") StringReplace(GUICtrlGetData($Label1), "fli?", "Flirtiamo?")

      As with a lot of programming, the less manual repetition done to achieve the same outcome...the better.
      I package programs for network deployment at the organization I work for. Sometimes these applications require verbose messaging to the user, and sometimes by special request we have to turn that off and deploy silently.
      The way I currently handle these 2 scenarios is this.
      I have a function that builds the splashwin display screen to variable size depending on message length, and displays the desired message to the end user.
      Then at each point throughout my script as I need to make the user aware of what is currently happening, I inject a splashwin function call with the unique message pertaining to that specific event. ie. "Installing Microsoft Office, please wait..."
      In effort to build a more universal script to handle any type of request submitted. I've incorporated a switch command of '/silent'
      If cmdlineraw detects the usage of that switch when the script is triggered it sets a variable flag, ie. $silent = "on"
      Then at every splashwin call I make, I'm prefixing it with an IF statement that checks for the flag, and then does NOT display the message if that flag is "on". Or does display it if its not. Has worked for me just fine. But while I grow my programming skills and look for more streamlined ways of handling areas I find myself creating repetition. I'm curious if I can relocate that flag check. Taking it out of every single splashwin call, and injecting it into the function itself.
      Example of how I currently display or hide the splashwin based on command line...
      If StringInStr($cmdlineraw, "/silent", 0) Then
          $SilentSwitch = "ON"
      EndIf
      If $SilentSwitch = "OFF" Then SplashWin($Uninstalling & $ProductInfo[1][0])
      Some scripts have dozens of those splashwin calls littered throughout, so Is this the best approach I can take already? Or as stated earlier, can I pull the IF statement away from the splashwin call. And left the function as a whole either activate or deactivate as a result of the command line check.

      Hi,
      I wonder if
      AutoIt3Wrapper_run_debug_mode = Y can include run information about functions which are called within the main code. So far I noticed in the console that the function itself is called but no specific run information from  inside the function is provided. Is there a chance to show the entire debug log including functions in the console?
      I furthermore noticed a stop of information when a loop is entered. What could be the reason for that?
       
      Thanks for help.
