Hi Ricki,
I have a minute so why not answer in short.
I'll explain two ways:
Split function:
arr = Split(a_string,",")
Will split the string into array using the specified delimiter. But I think
this is not
good way to deal with the multiply choices listboxes.
Using the strings collection:
If your listbox is like this <SELECT NAME="MyLB">....
Then you will ceive in the Request("MyLB") all the selected values.
In fact they are in a collection that can be looped as an array and the
comma
delimited result is returned only as an alternative. So you can do these
things
x = Request("MyLB").Count
will return the number of the values (the selected values)
x = Request("MyLB")(4)
will return the 4-th value
E.g you can do this
For I = 1 To Request("MyLB").Count
x = RequesT("MyLB")(I)
' Do something with it
Next
Or if you prefer enumerations do this
For each e in Request("MyLB")
' do something with the e - it contains the value
Next
I recommend you the second way - the collection because this will save a
little memory
and in fact acts like an array. Also using split may lead to some mistakes
if certain value contains
the delimiter in it. This sounds impossible for a listbox but who knows - it
is better to use the safest
way.

Subject: convert string to array
I know this has to be simple, but I'm not finding the answer and I've never
tried it before. I have a list box where they can make multiple selections.
A sample return from the box is: African, African - American, Aleutian,
American Indian, Asian, Bangladeshi, Bhutanese, Brazilian
My question is, how do I loop through this string and change it into an
array so I can loop through it for later processing? Or should I even
convert it to an array if I can loop through the string just as easily? If
that's the case, then I'm still back to - How do I loop through a string?
thanks,
Ricki
