subscript dimension range exceeded

[Vindicator209]

Sorry I'm new to this whole dimension thing, but whats wrong with this:

Dim $A[30][30]
For $x = 0 to 30
    For $y = 0 to 30
        $A[$x][$y] = GUICtrlCreatePic($Tiles & "Empty.bmp",$x * 25,$y *25,25,25)
    Next
Next

I figure its something with the Dim line

You will probably have to change the dim to [31][31] But you should change

For $x = 0 to 30

to

For $x = 0 To Ubound($A)-1

Thanks... but what exactly doest that do?

For $x = 0

Starts the iteration (loop) at 0,

To Ubound($A)-1

Iterates (loops) through values of x until it reaches Ubound($A)-1

Which is a way of determining the upper bound(the actual number of elements) of the array $A, minus one, so that you will never try to iterate through the loop more times than there are elements in the array.

Ah, thanks.

I can't believe I dodn't look that up earlier, that would have helped me so much in other projects.. lol

If the first element contains Data and not the number of elements then you use Ubound. It depends on how the array is built. For example StringSplit uses Array[0] to hold the number of elements so you can use For $I = 1 To array[0] or if the number of elements is known you can use For $I = 1 To Number of Elements.

In all situations you can use Ubound(Array) -1. The onnly thing that may change is the first element that contains data. It could be either 1 or 0.
