Notification Sample Application

Topic Last Modified: 2006-06-12

Notifications are used in many systems for performing event-based processing. Event-based processing is useful in a Web-based document storage environment because it allows a client to perform actions based on changes in the state of the server. If the server is mail-enabled, these notifications may be used to inform the client of the arrival of new mail or changes to a resource. For more information about notifications, see WebDAV Notifications. For more information about notification types, see Notification-Type Header.

The Notification Sample Application uses the WebDAV protocol to subscribe to new mail, delete, and update events in a public or mailbox folder in the Exchange store. The Notification Sample Application consists of a Microsoft® Visual Basic® .NET user interface and a Microsoft C# class library. The C# class library provides a code wrapper for the SUBSCRIBE Method, the POLL Method, and the UNSUBSCRIBE Method, and can be used to create a subscription on a collection or resource in an Exchange store. The Visual Basic .NET user interface uses the C# class library to subscribe to a resource in an Exchange store and poll the Microsoft Exchange server for event notifications. The Notification Sample Application can be used on a computer that is not running Exchange Server 2007 . It must be used on a computer that has the Microsoft .NET Framework installed.

This sample application is intended for instructional purposes and is not meant to be installed in a production environment.
