Vips,

In the sample you are asking it, I would just create it new everytime.

dim arr(dt.Columns.Count-1) as string

Normally for a dynamic array you could use the arraylist or any other
dynamic arrayclass

I hope this helps,

\\\
arr = New String(dt.Columns.Count - 1) {}
///

- or -

\\\
ReDim arr(dt.Columns.Count - 1)
///

If you want to original content of the array to be copied to the new/resized
array, you can use 'ReDim Preserve'.
