Array within an array

7 posts in this topic

Hi

How can I put an array within an array? Found >this UDF, but did not understand how to use it.

Basically I have 2 columns (List of hotkeys)(ArrayHotkeyInfo) (look in the picture) in main array, Every hotkey has additional information. For example a list of windows associated with that key, this why I can not make one array.

I made an example, run it & see that F1 was added into an array. But how to add an array into the second column of th emain array and how to call data from that sub array?

With regards.

#Include <Array.au3>

Global $ArHotkeys[1][2]
global $ArHotkeyInfo[1][3]

_HotKeySet("{F1}", "Mozilla Firefox", 1, "Enabled")
_ArrayDisplay($ArHotkeys, "$ar_hotkeys")

Func _HotKeySet($HOTKEY, $WINDOW, $WinTitleMatchMode, $ENABLED_DISABLED_STATE)
    $hotkeypos = _check_if_hotkeyexists($HOTKEY)
    if $hotkeypos <> 0 Then
        ConsoleWrite($hotkeypos& @LF)
    Else
        _add_key($HOTKEY)
    EndIf
EndFunc
#cs --------------------------------------------------
;## Check if a hotkey exists if yes return its position
#ce --------------------------------------------------
func _check_if_hotkeyexists($HOTKEY)
    for $i = 0 to UBound($ArHotkeys) -1
        if $ArHotkeys[$i][0] = $HOTKEY Then return $i
    Next
    return 0
EndFunc
#cs --------------------------------------------------
;## Adds a hotkey
#ce --------------------------------------------------
func _add_key($HOTKEY)
    $iRow = UBound($ArHotkeys)  ;get Rows
    $iCol = UBound($ArHotkeys, 2)   ;get Columns

    ReDim $ArHotkeys[$iRow + 1][$iCol]  ; add more rows +1
    $ArHotkeys[$iRow][0] = $HOTKEY
EndFunc

Yes, you can, however its clunky to use.  I'm Dev'ing a medium sized program, and initially I thought an array inside of an array was my best solution, since it "looked better"

#include <array.au3>
 
Local $arr[2]
 
$arr[0] = "test"
$arr[1] = stringsplit("test array value 1|test array value 2","|")
_ArrayDisplay($arr[1])  ;this succeeds, but how do I access the data?
 

 

However, you cannot access that data without first assigning a temp variable:

#include <array.au3>
 
Local $arr[2]
 
$arr[0] = "test"
$arr[1] = stringsplit("test array value 1|test array value 2","|")
 
Local $temp = $arr[1]
 
_ArrayDisplay($temp)
msgbox(0,'',$temp[1])
 

 

In the end, it makes your code more hard to compartmentalize, as well as error check (in ideal code, you would IsArray($temp) every time before acting on the variables.).  I just spent a couple hours re-writing all of my sort/computations of my data from array of arrays to a 2d array and I feel much better about it.

kaisies,

Oh yes you can - since 3.3.10.0 released in December 2013! ;)

#include <MsgBoxConstants.au3>

Local $aInner[3] = ["A", "B", "C"]

Local $aOuter[1] = [$aInner]

$sElement = ($aOuter[0])[1] ; Note syntax!!!!

MsgBox($MB_SYSTEMMODAL, "Inner element", $sElement)
M23

This is wery nice, works, but how do you get the size of that inner array? See the example.

I cant just call ubound on the inner array because I plan to generate an aray for each hotkey.

Local $aOuter[1][2]
Local $aInner[1][3]

$aInner[0][0] = 'a'
$aInner[0][1] = 'b'
$aInner[0][2] = 'c'

$aOuter[0][1] = $aInner

ConsoleWrite(ubound(($aOuter[0][1])) & @CRLF) ;; does not work

for $i = 0 to 100
    ConsoleWrite(($aOuter[0][1])[0][$i] & @CRLF)
    if @error then ExitLoop                         ; does not work
Next

ConsoleWrite('->' & ($aOuter[0][1])[0][0] & @CRLF)

To me it say it return 1 (and that is correct result if you ask me).

If you're looking for columns instead of rows please open your help file and read UBound and its second parametar 'Dimension'.

PS: if you did not understand what im saying then _ArrayDisplay is your best frend  ;)

Ahh of course, it works, I just made 1. row in the sub array, this why it returns 1, my bad,

Thank you. :)
