Redim'ing a 2-dim array into 1-dim

[sshrum]

I have a 2 dimension array that I want to copy but I only need the first dim.

I tried

$a1DimArray = $a2DimArray
REDIM $a1DimArray[$a2DimArray[0][0]]

...hoping that the rest of the array would just be truncated off. I got back a single dimed array with the correct number of elements that were all blank.

Is this possible or do I have to parse the 2 dim array and move the values into the 1 dim array?

EDIT: Thinking about this some more I think I just have to parse the array...the first column I want is the 0 column of the second dimension...

Like this?

#include <array.au3>

Dim $array[10][2]

For $i = 0 To 9
    For $x = 0 To 1
        $array[$i][$x] = $i & ' ' & $x
    Next
Next

_ArrayDisplay($array)

ReDim $array[10][1]

_ArrayDisplay($array)

Yeah. That works.

Still a 2 dimension array...just with a signle dimension aspect.

Thanx

EDIT: No joy. It still is structured like a 2-dim array so calls to it have to be in the format: $array[$i][0].

I was hoping that I could get away with $array[$i] but after thinking about it, I'm pretty sure it isn't possible.

I'm trying to truncate a 2-dim into a 1 dim and that just isn't going to happen. What you did is truncate all but the first row of the second dim...but it's still a 2 dim array.

Nice try though.

Dim $tmp

For $i = 0 To 9
    $tmp &= $array[$i][0] & '|' 
Next

$newarray = StringSplit(StringTrimRight($tmp, 1), '|')

_ArrayDisplay($newarray)
