Re-ordering a simple array

Recommended Posts

BlazerV60

Hello everyone,

I created this small script that shows a list of 10 people in an array.

Each person is associated with a number which is stored in another array.

Chris is associated with 3, Brian with 4, Daniel with 2, Stephen with 6 and so on.

I then made the first array (with the names in them), to be sorted in alphabetical order.

How can I make the second array with the numbers in them, also sorted accordingly so that each person is still matched with their number?

#include <Array.au3>
#include <File.au3>

Local $Array1[10] = ["Chris","Brian","Daniel","Stephen","William", "Joseph", "Diana", "Thomas", "Jason", "Carol"]
Local $Array2[10] = [3, 4, 2, 6, 7, 1, 9, 10, 5, 8]

_ArraySort($Array1)
_ArrayDisplay($Array1, "Sorted in Alphabetical Order")

;Display Array2 showing the new sorted out rows, so that each person is still matched with the number they are associated with. Results should show 4, 8, 3, 2, 9, 5, 1, 6, 10, 7

Thanks,

Brian

Use a 2d array instead of 2x 1d arrays.

Like UEZ said, like this:

#include <Array.au3>

Local $Array1 = [ _
    ["Chris", 3], _
    ["Brian", 4], _
    ["Daniel", 2], _
    ["Stephen", 6], _
    ["William", 7], _
    ["Joseph", 1], _
    ["Diana", 9], _
    ["Thomas", 10], _
    ["Jason", 5], _
    ["Carol", 8] _
]

_ArraySort($Array1)
_ArrayDisplay($Array1, "Sorted in Alphabetical Order")

Thanks UEZ and jchd! That made sense and I was able to get the results I wanted thanks to the 2d array method.

I have one more question though,

jchd, you had to manually type out both of my columns in your code.

Is there a way to combine both of my original 1d arrays into a 2d array with 2 columns through some sort of autoit code? Because my arrays may have 1000 entries in each and it would take too long to manually type those out.

Thanks,

Brian

Of course there is the simple pedestrian way: use a For..Next loop with a single index used to read $Partial1DArray1, $Partial1DArray2 and write $Monster2DArray elements.

#include <Array.au3>

Local $Array1 = ["Chris","Brian","Daniel","Stephen","William", "Joseph", "Diana", "Thomas", "Jason", "Carol"]
Local $Array2 = [3, 4, 2, 6, 7, 1, 9, 10, 5, 8]

If UBound($Array1) <> UBound($Array2) Then
    MsgBox(0, "", "Big mistake")
Else
    Local $Array[UBound($Array1)][2]
    For $i = 0 To UBound($Array1) - 1
        $Array[$i][0] = $Array1[$i]
        $Array[$i][1] = $Array2[$i]
    Next
    ; optionally free both partial arrays
    $Array1 = 0
    $Array2 = 0
    _ArraySort($Array)
    _ArrayDisplay($Array, "Sorted in Alphabetical Order")
EndIf

      hi,
      i have checkboxes and each checkbox that checked, i put in array. 
      now, im stuck on how to loop the checked array and store in in one variable. what i can do now, is only write the result into a text file. 
      below is the code:
      #include <GUIConstantsEx.au3> ;~ #include <MsgBoxConstants.au3> #include <ButtonConstants.au3> #include <Array.au3> Global $Count = 3 Global $CheckBoxP[$Count] Global $step[$Count] global $array1[1] Global $ExitResult $hGUI = GUICreate("Summary Steps", 500, 400) GUISetFont(12, 400, "Tahoma") GUICtrlCreateLabel( "Please Select the Summary Steps for Script Check", 70, 20) GUISetFont(10, 400, "Tahoma") Global $array_Pstep[3] = ["fix2","fix1","fix3"] global $step[3] = ["2","3","4"] $Spacing = 50 For $i = 0 To UBound($array_Pstep) - 1 $CheckBoxP[$i] = GUICtrlCreateCheckbox($array_Pstep[$i], 80, $Spacing + (20 * $i), 65, 17) Next $submit = GUICtrlCreateButton("Submit",180, 280, 80, 30) $exit = GUICtrlCreateButton("Exit",180, 320, 80, 30) GUISetState() While 1 $Msg = GUIGetMsg() Select case $Msg=$submit For $i = 0 To $Count - 1 If GUICtrlRead($CheckBoxP[$i]) = $GUI_CHECKED Then _ArrayAdd($array1, $step[$i]) EndIf Next Global $logfilerray = @WorkingDir & "\checkedlist.txt" FileDelete ($logfilerray) Global $readlogfile = FileOpen($logfilerray,1) for $a = 1 to UBound($array1) - 1 ;~ $var=$array1[$a] FileWriteLine($readlogfile,$array1[$a]) Next FileClose($readlogfile) Exit case $Msg=$exit $ExitResult = MsgBox(1,"Summary Step", "Continue to Exit ?") if $ExitResult = 1 Then ;ok Exit EndIf Exit EndSelect WEnd

      How do you perform a nested loop function with a multidimensional array from 2 lists.
      for i in list1
      (open file) extract variable
          while open for i in list 2
          (open file2) extract variable
       
      var1 + var2 = (search term)

      The list sizes will more than likely consist of different lengths.
       
      What is the best approach to accomplishing this method?

      Hello!

      I am working on a function that I am just getting lost on. The goal is a multiple nested loop.

      Here are the steps:
      Contents of file1.txt::
      [topic] var1=Name var2=OtherName var3=SomeotheName Contents of file2.txt::
      [subTopic] top=sub1 top2=sub2 top3=sub3 The Shell I am working from::
      #include <file.au3> $file = "c:\yourfile.txt" FileOpen($file, 0) For $i = 1 to _FileCountLines($file) $line = FileReadLine($file, $i) msgbox(0,'','the line ' & $i & ' is ' & $line) Next FileClose($file) Understanding however that the "msgbox" needs to then become a variable. in example the following::
      $file = "c:\yourfile.txt" FileOpen($file, 0) While true( prog.exe is running && "WinName" is open) do For $i = 1 to _FileCountLines($file) $line = FileReadLine($file, $i) ;Open File to log "current location of file 1" FileWriteLine ("filename", $i & ' is ' & $line) var = $line Next $file2 = "c:\yourfile.txt" FileOpen($file, 0) For $i = 1 to _FileCountLines($file) $line = FileReadLine($file, $i) ; OpenFile to log "Current location of file 2" FileWriteLine ("filename", $i & ' is ' & $line) Next FileClose($file2) FileClose($file) The goal in written form is the following ::

      While in "OpenWindow"
          read from file 1 starting at line 1 until end of file.
         file 1 is a list of names to be searched.
         With $line selected, add this element to the element in file 2.
       
      The search of a variables in list 1 and list 2 differ on the amount of posts that day. (This is not a web based platform, it is a game) I need to search 2 names and take a screenshot of the out put. The sizes of the names list depend on the activity of names at the time of search.
      This loop continues until all the names from both lists have been searched. Mostly in the format of::
      File1= item
      File2= Vendor
       
      Item + Vendor  ( Capture screen, scroll) -- Not sure how to detect if I need to scroll)
       
      Thank you for your help and support!

      Hi Virtual People,
      My array works perfectly fine. However, what is the best practice if the line in the array doesn't have the correct amount of columns and if I can add a placeholder?

       
      For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") Next

      hi all,
      reviewing the forum, this thread is applicable: 
       
       
      I wanted to know if there is now a better way to do this?
      In essence, I load a tab delimited txt file into an array (works well). I used tab, as some fields in the original csv contains commas.
      However, I needed autoit to manipulate this array, and output it as a csv.
      IF my array contains items with a comma, without double quotes around the field, then how best do I get a csv out of this?
      My current workaround is to filewritefromarray tab delimited, then open it in excel and save as a csv. I will need to check this to see how the address fields behave that contain a comma.
       
      Any thoughts would be appreciated.
