getting the index of items in a listbox

[gmatteson]

i go through the listbox using

dim x as integer
dim intIndex as integer
for x = 0 to listbox.listcount
intindex = listbox.list(x).index

next x

i recieve an error..
i want to get the index of all the items in the listbox and put that in a variable as it goes throught the list... any ideas?
