Arrays

[motte]

Hi all,

Not really new to asp, but I'm a rookie on this topic as it pertains to asp. Do arrays always have to be defined with a dimension? Is it possible to create an array of undetermined size? Or would you have to create an array of, let's say, 10, and redimension it if someone only chooses 3 things?

I have no example of this or any hypotheical situation; I just want to know what kind of possibilities there are with arrays. Any code snippets would be very helpful too.

well, there are two things i would do:

1.)

Dim ary(0)
Dim i

For i = 1 to ItemCount '//Itemcount is the "unknown" amount of stuff i want to array
  ReDim Preserve ary(i)
  ary(i) = Item(i)
Next

2.)

Dim ary

ary = Array("one", "two", "three",...,"fifty")

Hope it helps. _________________

Bixarrio,

A few questions:
1. In part 1's assignment line,
ary(i) = Item(i)
is Item, as you refer to it, supposed to be ItemCount that you called it at the top of the loop?

2. Why do you need part 2 if part 1 adds the new element thru the loop?...or are 1 & 2 seperate cases?

Dim ary() ' Dynamic array
Redim ary(whateverUbound)

Redim Preserve(whateverUbound) ' Redim and save contents
