Active Server Pages (ASP) implement classes that enable your component to access the properties and methods of the ASP built-in objects. The ObjectContext object exposes methods that return an interface to one of the ASP built-in objects. Your component can use these interfaces to access the methods and properties of the built-in objects.
The following table lists the built-in object classes:
| Class | Use to |
|---|---|
| Application | Call the methods and properties of the Application object. |
| ObjectContext | Returns the built-in objects and provides methods used in transaction processing. |
| Request | Call the methods and properties of the Request object. |
| Response | Calls the methods and properties of the Response object. |
| ScriptingContext | Returns the built-in objects: Application, Request, Response, Server, or Session. |
| Server | Calls the methods and properties of the Server object. |
| Session | Calls the methods and properties of the Session object. |
To use the ScriptingContext and built-in object in a Visual Basic component, you must load the Microsoft® ASP Object Library (asp.dll) into your available references. This file is installed with the ASP feature in the \inetsrv\asp\ directory.
For more information about the built-in objects see Built-in ASP Objects Reference.
Note If you are using Visual Basic 5.0, you should create your component as an ActiveX DLL and not an ActiveX control.
