Hi Mr.,

Dim entryName as String

Response.Write("Name: " & entryName & "<br/>")

For Each makes a loop through items in collection of Request.Form,
and item is a string, specifying the name of the form field that's being
sent
Dim Item as String
For Each Item in Request.Form
Response.Write Item
Response.Write Request.Form(Item)
Next

Cheers dude.
G.
why does the thing need to be named "item"? or does it??
Dim AnyName as String

That's what I don't get.
if item can be named anything...
how does the procedure know that I want items, as opposed to any of the
other properties?
The collection of Request.Form has only item names and you can't get other
properties.
It is the same with any other collection, for example, when you have an
array of strings
Dim lines As String()
Dim line As String
For Each line In lines
Next
This code enumerates the strings in array.

well, given a collection, how are you supposed to know which is the default
property??
What do you mean by default property of collection?
According to MSDN:
Request.Form gets a collection of form variables. Its property value is
a NameValueCollection representing a collection of form variables. And
NameValueCollection Class represents a sorted collection of associated
String keys and String values that can be accessed either with the key
or with the index.
In other words, Request.Form is a collection of strings {"aa", "bb",
"cc"...}.
"aa" is a string which represent a name of a form variable
No properties.

Maybe the OP was referring to the default order of retrieval ?
When you do a call to the default Request collection,
each of the sub collections are searched in the following order:
1. QueryString
2. Form
3. Cookies
4. ClientCertificates
5. ServerVariables
The process stops when the first match is found.
Unfortunately, if there's same-name items in two or more sub collections,
you aren't guaranteed to receive the data you're looking for.
That's why you shouldn't use : Request("name")
You should use Request.Form("name") or Request.Cookies("name")
or Request.QueryString("name"), etc., always specifying the sub collection
you want to retrieve data from.

Well, the question was about Request.Form as I see. Anyway, you're
right, it has to be more detailed

I have a small suggestion for you.
Go through the basics of .Net Framework, VB.Net and Collections-API before
starting with ASP.Net
And I'm damn serious. You may really mess up your ASP.Net learning
otherwise.

what I mean is there are several properties of a form field
when i loop through the "items", how am I supposed to know which of the
properties i am looping through
for instance, request.form has items, keys, allkeys, count.
why doesn't this pull in the keys, rather than the items.
For Each entryName In Request.Form
Response.Write("Name: " & entryName & "<br/>")
Response.Write("Value: " & Request.Form(entryName) & "<br/>")
Next

For Each entryName In Request.Form

Response.Write("Value: " & Request.Form(entryName) & "<br/>")

For Each...Next loop is designed for collections and arrays only. It
means you could loop through elements of a collection or array only.
You can't loop through Count property because it's not a collection.
You can loop through Request.Form, Request.Form.Keys or
Request.Form.AllKeys collections.
For Each entryName In Request.Form.Keys
Response.Write("Name: " & entryName & "<br/>")
Response.Write("Value: " & Request.Form(entryName) & "<br/>")
Next
or
Dim loop1 As Integer
Dim arr1() As String
arr1 = Request.Form.AllKeys
For loop1 = 0 To arr1.GetUpperBound(0)
Response.Write("Form: " & arr1(loop1) & "<br>")
Next loop1
so how do you look at the screen and see what is a collection and what is
not?
what tells you? is there a certain color icon?

I think nobody write a code starting from For Each. I supposed you
know that the code above gave you sort of iterated array of results.
You can see the type of property when you writing its name in Visual
Studio or placing the mouse cursor over code (intellisense). For
example, for line of code with Request.Form it shows me two lines
tooltip
System.Collection.Specialized.NameValueCollection HttpRequest.Form
Gets a collection of form variables.
If intellisense is not working or you use another IDE you can always
refer to help (e.g. www.msdn.com) where you will get much more
details about each property. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics
