Active Server Pages implements interfaces that enable your component to access the properties and methods of the ASP built-in objects. The IScriptingContext interface contains methods that return pointers to the built-in object interfaces. Your component can then use these object interfaces to access the properties and methods of the built-in objects, or interfaces to the Request and Response object collections.
The following table lists the built-in object interfaces:
|
Interface |
Use to |
|
Return a pointer to an interface on one of the built-in objects: IApplicationObject, IRequest, IResponse, IServer, or ISessionObject. | |
|
Call the methods and properties of the Application object. | |
|
Call the methods and properties of the Request object. | |
|
Call the methods and properties of the Response object. | |
|
Call the methods and properties of the Server object. | |
|
Call the methods and properties of the Session object. | |
|
Retrieve the values stored in the read-only Cookies collection. | |
|
Index the subcollections of the IRequest interface. It is also used to retrieve the individual values stored in the ClientCertificate collection.. | |
|
Retrieve the values stored in a string list, such as that in the QueryString, Form, or ServerVariables collections. | |
|
Set the values and attributes of a cookie stored in the write-only Cookies collection. |
To use the IScriptingContext and object interfaces in a C++ component, you must include the header file Asptlb.h as shown in the following code. This file is installed with the Active Server Pages feature in the directory \Inetsrv\Asp\Cmpnts\.
#include "asptlb.h"
To create a component that uses the ActiveX™ Template Library (ATL) 1.1, you should install ATL on your machine and then select "ATL COM Appwizard" when creating a new project workspace in Microsoft® Visual C++®.
