The trick is to define the biggest array you will ever
possibly need (then double it to be sure), then when you
call listbox, have the size be the number of elements used
in the array. (Note that you can tell listbox to only
display part of the array elements, so count carefully).
If you don't give it a last entry position, it will just
display all elements, empty or full.

Examples:

dim fields(100)(10,*)

fields("1")="abc"
fields("2")="bcd"
fields("3")="cde"
x=listbox(fields,"1","3")

You can also do this:

x=listbox(fields,"2","4")

which will display only elements 2, 3 and 4 (which is blank).


I've been doing this for many years and it still works great.
