Read _arraymax with multiple dimensions

[wipped]

Hi

I got this:

#include <Array.au3>

Local $avArray[10]

$avArray[1][0] = "TD0001"
$avArray[2][0] = "TD0002"
$avArray[3][0] = "TD0003"
$avArray[4][0] = "TD0004"
$avArray[5][0] = "TD0005"

MsgBox(0,'Max String value', _ArrayMax($avArray, 0, 1))
$sInput = _ArrayMax($avArray, 0, 1)


$sAlpha = StringMid($sInput, 1, 2)
$sNumeric = StringMid($sInput, 3)
$sNumeric = StringFormat("%04i", Number($sNumeric) + 1)
$sOutput = $sAlpha & $sNumeric
MsgBox(0, "Result", $sOutput)

And how can i read the highest value like this?

Thanks, RJ

wipped,

I would create a temporary 1D array of the relevant dimension of the 2D array like this:

#include <Array.au3>

Local $avArray[6][2]

$avArray[1][0] = "TD0001"
$avArray[2][0] = "TD0002"
$avArray[3][0] = "TD0003"
$avArray[4][0] = "TD0004"
$avArray[5][0] = "TD0005"

Local $aTemp[UBound($avArray)]
For $i = 1 To UBound($avArray) - 1
    $aTemp[$i] = $avArray[$i][0]
Next

MsgBox(0,'Max String value', _ArrayMax($aTemp, 0, 1))
$sInput = _ArrayMax($aTemp, 0, 1)

$sAlpha = StringMid($sInput, 1, 2)
$sNumeric = StringMid($sInput, 3)
$sNumeric = StringFormat("%04i", Number($sNumeric) + 1)
$sOutput = $sAlpha & $sNumeric
MsgBox(0, "Result", $sOutput)

Does that do it?

Thanks alot it works,

But can you tell me what Local $avArray[6][2] does?

wipped,

Did you try to run your initial code? Obviously not, or you would have seen the error: "Array variable has incorrect number of subscripts or subscript dimension range exceeded" when you tried to set the elements.

Local $avArray[6][2] declares a 2D array which you need when setting the elements using $avArray[1][0] = "TD0001".

You need the declaration to match the subsequent usage of the array. Even ReDim requires the number of dimensions to remain constant - it only allows you to vary the number of elements within a dimension.

All clear? Ask again if not.

Thanks for the help

But it's good to know for the future so you don't post questions like "How can I change the size of an Array when I don't know how big it will be!" And like Melba23 I am confused to how your first script worked?!
