how do redim a 2 dimesional array?

[Anonymous]

Dim arLayerData(100, 5) As String

was at first then i need to adjust the 100 to the real number of layers but
keep the 5 the same?

As far as I know an Dynamic Array must be first declared without bounds.

Dim asLayerData () as String

'then later add the bounds

ReDim arLayerData(50, 5) as string

'or if you wish to preserve existing info in the array use this

ReDim Preserve ArLayerData(70,5) as string

Hi,

One more restraint.

If you use REDIM PRESERVE you can only change the last parameter.

eg
dim ss() as integer
redim ss(5,0)
ss (5,0) = 2
for x = 1 to 200
redim preserve ss(5, 0 to i)
ss(5,i) = i
next i

You can't do
dim ss() as integer
redim ss(0,5)
ss (0,5) = 2
for x = 1 to 200
redim preserve ss( 0 to i, 5)
ss(i,5) = i
next i"

Yes, I lost nearly an hour until I finally read that in the help.

Why don't you just reverse the order of your dimensions so that you can
resize as needed?
Dim arLayerData(5, 100) As String
