Using Built-in ASP objects
ASP also provides built-in objects for performing useful tasks that simplify
Web development. For example, you can use the Request object to easily access
information associated with an HTTP request, such as user input coming from HTML
forms or cookies. Unlike using the objects provided by a COM component, you do
not need to create an instance of an ASP built-in object to use it in your scripts.
These objects are automatically created for you when the ASP request starts processing.
You access the methods and properties of a built-in object in the same way in
which you access the methods and properties of a component's objects, as described
in this topic.
Calling an Object Method A method is an action you can perform on an object
or with an object. The syntax for calling a method is:
Object.Method
parameters
The parameters vary depending on the method. For example, you can use the Write
method of the Response built-in object to send information to the browser as
shown in the following statement:
<% Response.Write "Hello World" %>
Note Some scripting languages do not support the Object.Method syntax. If your
language does not, you must add an entry to the registry in order to use that
language as your primary scripting language. See Working with Scripting Languages
for more information.
Setting an Object Property
A property is an attribute that describes the object. Properties define object
characteristics, such as the type of the object, or describe the state of an
object, such as enabled or disabled. The syntax is: Object.Property You can sometimes
read and set the value of a property. In addition, for some objects, you can
also add new properties. For example, the Ad Rotator component has a property,
Border, which specifies whether the ad has a border around it and determines
the border thickness.
The following expression specifies no border:
<% MyAds.Border = 0 %>
For some properties, you can display the current value by using the ASP output
directive. For example, the following statement returns TRUE if the browser is
still connected to the server:
<%= Response.IsClientConnected %>
