2 dimenision array

[blenkhn]

How does one lopp through a two dimension array if one doesn't know the length of the second array.

Rows are easy but what about the columns. the columns can be any number from 1 to 10

Any Help is appreciated.

Hi,

See help file

ubound($ar_Array,2) gives the 2nd dimension size

(cf my Array2.au3 function from linkin signature)

Also just wanted to point out that in AutoIt, the first entry in an array is the [0] entry (or the [0][0] entry in a 2-d case).

Dim $Array[5][3]
$dim1 = UBound($Array,1);5
$dim2 = Ubound($Array,2);3
MsgBox(1,"",$dim1 & " entries in dimension 1.") 
MsgBox(1,"",$dim2 & " entries in dimension 2.")
$Array[0][0] = "xxx"
MsgBox(1,"","'" & $Array[0][0] & "'" & " is the entry 0,0.")
$Array[5][3] = "zzz";error: dimension range exceeded
MsgBox(1,"","'" & $Array[5][3] & "'" & " is the entry 0,0.")

This script is fine until the last 2 lines. Even though I declared the array to be [5][3], when I try to write to the [5][3] entry it doesn't work because it doesn't exist. The last entry would be [4][2].

When you use the UBound command for each dimension you will still get 5 and 3 for the first and second dimension respectively.

I would assume this holds true for any number of dimensions.

Personally I think this is rather inconvenient and casue me a few problems until I figured this out. I'm just used to working with matrices where the first entry is [1][1].

Hope this helps.
