ASP implements interfaces that enable your component to access the properties and methods of the ASP built-in objects. You should use the COM+ IObjectContext interface to access the ASP built-in object interfaces. Your component can then use the ASP built-in object interfaces to access the properties, methods, and collections of the ASP built-in objects.
The following table lists the ASP built-in object interfaces:
Interface |
Description |
|---|---|
Provides access to the methods of the Application Object object. |
|
Returned by the IServer::GetLastError method. Provides access to the read-only properties describing the last error event. |
|
IObjectContext |
Returns an interface to one of the ASP built-in objects: IApplicationObject Java Interface, IRequest Java Interface, IResponse Java Interface, IServer Java Interface, or ISessionObject Java Interface. Provides transaction control. For more information about the COM+ ObjectContext object, see Accessing ASP Built-In Objects from Components Reference. For complete information on the IObjectContext interface, see the COM+ Programmer's Reference of the Software Developer Kit (SDK). |
Provides access to the values stored in the read-only Request object Request.Cookies Collection collection. |
|
Provides access to the methods and properties of the Request Object object. |
|
Indexes the sub-collections of the IRequest interface. You can also use it to retrieve the individual values stored in the Request.ClientCertificate Collection collection. |
|
Provides access to the methods and properties of the Response Object object. |
|
IScriptingContext C++ Interface (Obsolete) |
Returns a pointer to an interface on one of the ASP built-in objects: IApplicationObject C++ Interface, IRequest C++ Interface, IResponse C++ Interface, IServer C++ Interface, or ISessionObject C++ Interface. This interface is no longer supported. Instead, use the COM+ IObjectContext interface. |
Provides access to the methods and properties of the Server Object object. |
|
Provides access to the methods and properties of the Session Object object. |
|
Provides access to the values stored in a string list, such as that in the Request.QueryString Collection, Request.Form Collection, or Request.ServerVariables Collection collections. |
|
Provides access to the items stored in the Application and Session Contents and StaticObjects collections. |
|
Sets the values and attributes of a cookie stored in the write-only Response object Response.Cookies Collection collection. |
Microsoft ? Visual C++ ? provides the ActiveX ? Template Library (ATL) 1.1 to make the development of COM components faster. To use ATL, select ATL COM Appwizard when you create a new project workspace.
To use the IObjectContext object interface in a C++ component, you must include the header file Comsvcs.h (formerly known as Mtx.h) as shown in the following code:
#include "comsvcs.h"
To use the IScriptingContext object interface in a C++ component, you must include the header file Asptlb.h as shown in the following code:
#include "asptlb.h"
These header files are part of the Software Developer Kit (SDK).
