Range function to create instant integer arrays

3 posts in this topic

#1 ·  Posted (edited)

Hi all,

Here is new UDF to create integer arrays instantly. 

#cs ----------------------------------------------------------------------------

 AutoIt Version: 3.3.12.0
 Author:         kcvinu

 Script Function:This function will give you an array of integer
                 If you give only Stop_Number, it will give you an array[stop_number]
                 Example => Range(9) = [0,1,2,3,4,5,6,7,8,9]
                 If you give both parameters, it will give you an array [start_number to stop_number]
                 Example => Range(9,3) = [3,4,5,6,7,8,9]
                 If you give step number, it will add the elements by step number
                 Example => Range(9,3,2) = [3,5,7,9]
    Template AutoIt script.

#ce ----------------------------------------------------------------------------

; Script Start - Add your code below here

#include <Array.au3>
Func Range($To_Number, $From_Number = 0, $Step_Number = 1)

    If $From_Number < 0 Then
        MsgBox(0, "Range Function", "From Number must be > 0")
    ElseIf $To_Number < $From_Number Then
        MsgBox(0, "Range Function", "To Number must be > From Number")
    ElseIf $Step_Number > $To_Number Then
        MsgBox(0, "Range Function", "Step Number must be < To Number")
    EndIf

    If $From_Number = 0 And $Step_Number = 1 Then
        Global $ReturnArray[$To_Number + 1]
        For $Element = 0 To $To_Number Step $Step_Number
            $ReturnArray[$Element] = $Element
        Next
        Return $ReturnArray
    ElseIf $From_Number = 0 And $Step_Number > 1 Then
        Local $index = 0
        Local $TempVar1 = 0
        While $TempVar1 <= $To_Number
            $TempVar1 += $Step_Number
            $index += 1
        WEnd
        Global $ReturnArray[$index]
        For $j = 0 To $index-1
            $ReturnArray[$j] = $From_Number
            $From_Number += $Step_Number
        Next
        Local $LastIndex = (UBound($ReturnArray)) -1
            if $ReturnArray[$LastIndex] > $To_Number Then
            _ArrayDelete($ReturnArray,$LastIndex)
            EndIf
        Return $ReturnArray

    ElseIf $From_Number > 0 Then
        If $Step_Number = 1 Then
            Local $Diff = ($To_Number - $From_Number) + 1

            Global $ReturnArray[$Diff]
            Local $index = 0
            For $Element = $From_Number To $To_Number
                $ReturnArray[$index] = $Element
                $index += 1
            Next
            Return $ReturnArray

        ElseIf $Step_Number > 1 Then
            Local $TempVar1 = $From_Number
            Local $index = 0
            While $TempVar1 < $To_Number
                $TempVar1 += $Step_Number
                $index += 1
            WEnd

            Global $ReturnArray[$index + 1]
            For $j = 0 To $index
                $ReturnArray[$j] = $From_Number
                $From_Number += $Step_Number
            Next
            Local $LastIndex = (UBound($ReturnArray)) -1
            if $ReturnArray[$LastIndex] > $To_Number Then
            _ArrayDelete($ReturnArray,$LastIndex)
            EndIf
            Return $ReturnArray

        EndIf
    EndIf

EndFunc   ;==>Range
 

If you want to create a list of integers, you can use this like Local $List = Range(12,2,2)

This will make an array like this => [2,4,6,8,10,12]

Hi all,

Last day, i found some bugs in my Range.au3 script and i have debugged all. Now i have edited my post and updated the Range.au3 file. So I am requesting those who downloaded (I found 6 downloads) this file last day, please delete that file and use the updated Range.au3. Thank you all. :)

Thanks for contributing!

Here is another version (not extensively tested):

#include <Array.au3>

Const $test1 = Range(9)
Const $test2 = Range(9, 3)
Const $test3 = Range(9, 3, 2)
Const $test4 = Range(9, -3)
Const $test5 = Range(9, -3, 2)

_ArrayDisplay($test1, "Range: 9")
_ArrayDisplay($test2, "Range: 3 - 9")
_ArrayDisplay($test3, "Range: 3 - 9 -- Step: 2")
_ArrayDisplay($test4, "Range: -3 - 9")
_ArrayDisplay($test5, "Range: -3 - 9 -- Step: 2")

Switch @error
  Case 1
    MsgBox(0, "Range Function", "To Number must be > From Number")
  
  Case 2
    MsgBox(0, "Range Function", "Step Number must be < To Number")
EndSwitch

Func Range(Const $To_Number, Const $From_Number = 0, Const $Step_Number = 1)
    Select
      Case $To_Number < $From_Number        
        Return SetError(1, 0, False)
      
      Case $Step_Number > $To_Number
        Return SetError(2, 0, False)
    EndSelect
    
    Local Const $upbound = _get_upbound($To_Number, $From_Number, $Step_Number) + 1
    
    Local $range[$upbound]
    
    Local $inc = $From_Number
    
    For $i = 0 To $upbound - 1
      $range[$i] = $inc
      
      $inc += $Step_Number 
    Next
    
    Return $range
EndFunc

Func _get_upbound(Const $To_Number, Const $From_Number, Const $Step_Number)
  Local $upbound
  
  Select        
      Case $From_Number < 0
        $upbound = (Abs($From_Number) + $To_Number)
        
      Case Else
        $upbound = ($To_Number - $From_Number)
  EndSelect
  
  Return ($Step_Number > 1) ? ($upbound / $Step_Number) : ($upbound)
EndFunc

      So I have a loop that keeps reading data from an array and searching it for the same value. If the value is no there it does work then adds the value to the array to prevent it from doing the same work.
      If _ArraySearch($ID,$filearray[$i]) = -1 Then Work.... _ArrayAdd($ID,$filearray[$i]) EndIf This is in a for loop hence $i
      So what is happening is the code works great for several hours. After a period of time _ArraySearch($ID,$filearray[$i]) will result in -1 even if $ID = $filearray. So it ready as if there is no data in the array. Anyone have this problem? 
       
      Also I am just running in using F5 not compiling it and running it if that makes a difference.

      Is there any way it could be done?
      I tried a lot of ways but maybe somebody know's the right way?

      I am reading a CSV file which is tab seperated as below.
      Local $aArray = FileReadToArray($file) And now, I am splitting this main array record wise so that Array contains internally another arrow to represent each row.
      For $i = 0 to (UBound($aArray) - 1) ;MsgBox(0,"",$aArray[$i]) $aArray[$i] = StringSplit(StringStripCR($aArray[$i]), Chr(9),2);Chr(9) for tab ;_ArrayDisplay($aArray[$i]) Next Afther that, _ArrayDIsplay is able to see the individual internal arrays.
      _ArrayDisplay($aArray[1]) But If I try to access the individual element of it as below.It is not showing any result.
      MsgBox(0,"",$aArray[1][1]) Any suggestion, below is the sample csv file.

      Need some help understanding why the ConsoleWrite works inside 2nd For loop but not out side. Between Audit Wiki, Help file , Forum searching (lots of code reading), and YouTube ( shout out to TutsTeach), I have not been able to find the reason why. 
      $sIniPath = "installLog.ini" ; - Get section name $iniSctionNames = IniReadSectionNames($sIniPath) ; - Get Keys and Vaules For $a = 1 to UBound($iniSctionNames) - 1 $keys = IniReadSection($sIniPath , $iniSctionNames[$a]) For $b = 1 to UBound($keys) - 1 $oldSysInfo = IniRead($sIniPath , $iniSctionNames[1], $keys[$b][0], "") $PntIPInfo = IniRead($sIniPath , $iniSctionNames[2], $keys[$b][0], "") $NewPCInfor = IniRead($sIniPath , $iniSctionNames[3], $keys[$b][0], "") ;ConsoleWrite($oldSysInfo & @LF) Next ;ConsoleWrite($oldSysInfo & @LF) Next ConsoleWrite($oldSysInfo) My intention is to use the variables later for Listboxes. Any explanation, forum post links or whatever would help. Sorry also very very new to Autoit.
      Also here's the ini file.
