Objects and collections

[Roland Hall]

I have two questions which I am unable to find answers to:

1. What is the difference between Request.Form and Request.Item?

I can do this:

dim obj, postback, o
postback = Request.Form("postback")
if postback <> "" then
for each obj in Request.Form
o = Request.Item(obj)
if o <> "postback" then
session(obj) = o
end if
Response.Write session(obj) & "<br />" & vbCrLf
next
end if

What makes Request.Item different in this respect than Request.Form? Is
there a benefit one way or the other?

2. Is it possible to use FOR...EACH, with a form and make the variable an
object?

Ex.

If I use:
for each obj in Request.Form

obj is not an object as I cannot then write:

Response.Write obj.value to get the value of the form variable.

If my form was:

<input type="text" name="iname" value="" />

and I typed in Roland and submitted, I cannot with the FOR...EACH use
obj.value to get the value. Is there a way to do it that I am not aware of?

TIA...

Request.Item(something) is the same as Request(something). Basically, Item
is the default property, and you've requested the first itme in all the
Request object's collections whose key matches your specification

I'm sure you've read all our admonitions in the past about failing to
specify the collection whose item you wish to retrieve...

for each key in Request.Form
Response.Write key & ": " & Response.Form(key)
next

key is the form element
Response.Form(key) would return the value but how can I make key an object
and use key.value to get the value?

Actually, it is the key of the form element
Response.Form(key) would return the value but how can I make key an
object and use key.value to get the value?

Unfortunately, the vbscript enumerator does not work that way with these
collections. The enumerator exposes the item keys, not the items themselves.
It took me a while to figure this out, so I feel your pain.

That's unfortunate. Well good for me that I have you to provide that answer
so my insanity will not come from trying to figure this one out. Thanks
Bob.
