Help with array first element

4 posts in this topic

Hi folks,

I'm very new to arrays, and I'm struggling with it a bit. I'm trying to read some settings from an INI file to an array and I then want to index the list stored in the array so that the first element in the array contains the number of items in the list (am I explaining this correctly?)

Here's a snip of the code I'm working on. Please could someone explain where I'm going wrong?

#include <array.au3>

Global $aVolLabels[1]
$strSettingsIni = @ScriptDir & "\Settings.ini"

$strTotalPart = IniRead($strSettingsIni, "Partitions", "Total", "")

For $i = 1 to $strTotalPart
    _GetVolLabel($i)
Next

_ArrayPop($aVolLabels); Remove last empty line from array
_ArrayDisplay($aVolLabels, "Volume Labels")

Func _GetVolLabel($i)
    ;Handle Volume Labels
    $strVolLabel=IniRead($strSettingsIni, "Partitions", "Label" & $i, "")
    ;MsgBox(0, "$strVolLabel", $strVolLabel)
    _ArrayInsert($aVolLabels, $i-1, $strVolLabel)
EndFunc

The INI file contains the following:

[PARTITIONS]
Total=3
Label1=System
Label2=Data
Label3=Temp

Any help or advice is welcomed!

Many thanks,

Greg.

gregnottage,

As you have the count in the ini file, just use that as the first element of your array: :)

#include <array.au3>

Global $aVolLabels[1]
$strSettingsIni = @ScriptDir & "\Settings.ini"

$aVolLabels[0] = IniRead($strSettingsIni, "Partitions", "Total", "")

_ArrayDisplay($aVolLabels)

For $i = 1 to $aVolLabels[0]
    _GetVolLabel($i)
Next

_ArrayDisplay($aVolLabels)

Func _GetVolLabel($i)
    ;Handle Volume Labels
    $strVolLabel = IniRead($strSettingsIni, "Partitions", "Label" & $i, "")
    _ArrayAdd($aVolLabels, $strVolLabel)
EndFunc

Is that what you wanted? :(

Thanks Melba - sometimes the easiest solutions are just staring you in the face, eh?! Very nice - thanks very much for that. It certainly does what I need.

Just out of curiosity, and for my future use and understanding of arrays, is there some way of indexing the list? I'm still trying to get my head around arrays and learning more about them.

Many thanks,

Greg.

gregnottage,

is there some way of indexing the list?

I am not sure what you mean. Arrays are indexed by the element number ([0], [1], [2], etc) - what else do you need? :(

P.S. When you reply please use the "Add Reply" button at the top and bottom of the page rather then the "Reply" button in the post itself. That way you do not get the contents of the previous post quoted in your reply and the whole thread becomes easier to read. :)
