access array index by name

[botanic]

is there any way i can access an array via its index name rather then a number

I have the following array and

$usersettings[1][1]

works however

$usersettings['vss'][1]

does not

 

[0]|10|
[1]|vss|4
[2]|username|
[3]|password|
[4]|compress|6
[5]|limitbw|4
[6]|bwlimit|
[7]|index|4
[8]|backuplength|30
[9]|systemstate|4
[10]|systemstatepath|

_ArraySearch() will give you the index of the element where a string is found. here's a small example:

#include <Array.au3>

Dim $a[4][2]

$a[3][0]='vss'
$a[3][1]=4
; the rest of the array is empty

MsgBox(0,'',$a[_ArraySearch($a,'vss')][1])

What you are looking for are associative arrays.

Check the UDF by Nutster: '?do=embed' frameborder='0' data-embedContent>>

botanic,

When I want to refer to an array index by some name instead of offset I do it like this...

#include <array.au3>

local enum $vss = 1, $username, $password, $compress, $limitbw, $bwlimit, $index, $backuplength, $systemstate, $systemstatepath

local $array[10] = [10]

$array[$username] = 'some user name'
$array[$password] = 'some password'
$array[$systemstate] = 'FUBAR'

_arraydisplay($array)

The drawback to this technique is that the ENUM defs have to be kept in sync with the array (if you expand or contract the array at some point).

I've never used the UDF pointed to by hannes08.  It may eliminate this problem.

One other alternative is to use the dictionary object.

kylomas,

One way of keeping the Enums and the array in sync is to do this (taken from one of my scripts):

Local Enum $eStart, $eReset, $eRepeat, $eReload, $eFile, $eRecent, $eZone, $eRepeat_Option_State, $eZone_Option_State, _
        $eFolder_Name, $eFolder_Alias, $eFolder_Data_File, $eMax
Local $aParam_List[$eMax]

Now the array will always have the correct number of elements - and if you want a count in [0] it is easy to arrange.

@M23 - Thanks...

and you do not know what in the beta already have unofficial support for associative arrays?

Local $table[]
$table['vss'] = 'hello)'
ConsoleWrite($table['vss'] & @LF)

Inververs,

That functionality is not complete or stable, will certainly not be supported by any of the AutoIt team and is completely undocumented as to its proper use - plus it could be removed at any time. I strongly suggest that people do NOT start using it until such time as it is formally announced as at least an "Experimental" item - perhaps in an eventual 3.3.11.## Beta.

well, let's hope that this feature will make part Autoit.

tnx
