 ServerVariables
- collection retrieves the values of
predetermined environmental variables.
Request.ServerVariables (server
environment variable)
Where (server environment variable) specifies
the name of the server environment variable to retrieve.
It can be one of the following values for example:
QUERY_STRING - Query information stored in
the string following the question mark (?) in the HTTP request.
Enumerator
Description
Provides a way to enumerate items in a collection.
Syntax
new Enumerator(collection)
The collection argument is any collection object.
Remarks
Collections differ from arrays in that the members of a collection are
not directly accessible. Instead of using indices, as you would with
arrays, you can only move the current item pointer to the first or
next element of a collection.
The Enumerator object provides a way to access any member of
a collection and behaves similarly to the For...Each statement
in VBscript, which repeats a group of statements for each element in
an array or collection.
For Each element In group
[statements]
[Exit For]
[statements]
Next [element]
- array
- A set of sequentially indexed elements having the same type of
data. Each element of an array has a unique identifying index
number. Changes made to one element of an array do not affect the
other elements.
-
- collection
- An object that contains a set of related objects. An object's
position in the collection can change whenever a change occurs in
the collection; therefore, the position of any specific object in
the collection may vary.
