How to create unknown array size ?

[pinkfoyd]

hi all !

can someone can help me explan why i can do this :

dim $test

$test[0] = 1

that return :

test.au3 (2) : ==> Badly formated variable or macro.:

$test[0] = 1

$test^ ERROR

because i don't like create a very large array ( ie : dim $test[999] )

they are no solution for create a dynamicaly extentable array ?

hope my explanation was clear

Have a script to look at?

Probably because you are not creating $test as an array to start with, then trying to access it as an array.

I think that I usually _ArrayCreate.

i.e. (untested)

dim $test = _ArrayCreate ( 1 )

Dim $test
;do some code
If Not IsArray($test) Then
   Dim $test[1]
Else
  ReDim $test[Ubound($test) + 1]
EndIf
$test[Ubound($test) - 1] = 1

ok grafost,

as i understand, the only solution is to do a resize of the array for each element i need to insert..

thanks !

Hi!

I am not sure about the last post. How do you resize an array?

If what I think is you mean to do is

$test = _ArrayCreate ( 1 )

;later wen I need to resize
$test = _ArrayCreate ( 2 )

Will resizing an array everytime reset it's variable?

That is to say, if I have created an array of size 1 having a value say "name" and then I resize it to 2 as shown above, will the value of array[1] still be "name"?

[ChrisL]

What about _ArrayAdd?

#include <Array.au3>

_ArrayAdd ( $avArray, $sValue )

Remarks

The ReDim keyword is similar to Dim, except that ReDim preserves the values in the array instead of removing the values while resizing an array. The number of dimensions must remain the same, or the old array will be forgotten during the ReDim. The array will retain the scope (Global or Local) that it had prior to resizing.

Yeah...got it!

Thanx ChrisL and JdeB for the infos.

This seems to be a nice feature...gonna experiment with it more.
