Is it a bug?? in Array index value

4 posts in this topic

I just wonder whether this display is correct??

I had this array and its position [0][0] gives us the total number of rows and cols, which is "13"

Once after deleting one row, how come it still shows the same number 13, eventhough it has only 12 rows

No bug, just lack of understanding. The help file will help.

This example works.

#include <Array.au3>

Local $avArray[10][2] = [[9, 2],["", "Holger"],["", "Jon"],["", "Larry"],["", "Jeremy"], _
        ["", "Valik"],["", "Cyberslug"],["", "Nutster"],["", "JdeB"],["", "Tylo"]]

_ArrayDisplay($avArray, "$avArray BEFORE _ArrayDelete()")
_ArrayDelete($avArray, 8)
$avArray[0][0] = UBound($avArray) - 1
_ArrayDisplay($avArray, "$avArray AFTER _ArrayDelete()")

Yup, Ubound works....but all iam asking is that, shud it not show the correct number of rows as 12 (without forcibly using Ubound)?

nbala75,

No. AutoIt will often give you the number of elements in the [0] (or [0][0])) element of an array as part of the array creation function but it is up to you to adjust the count if you alter the number of elements in array. :x

Remember that many arrays do not have a count in that element - AutoIt cannot read your mind to know whether to alter that element or not. And it is not too difficult to do it yourself - add 1 if you add an element, subtract 1 if you delete one. :P
