Application Object

An application on the Web can be a group of ASP files. These ASP files work together to accomplish a certain task. The Application object is used to tie these files together.

The Application object is used to store and access variables from any page, similar to the Session object. The difference is that all users share one Application object, while the Session object has a one-to-one relationship with each user.

The Application object stores information (such as database connection information) that is used by many pages in the application. This information can be accessed from any page. You can also change this information in one place, and the changes will automatically be reflected on all pages.

The collections, methods, and events of the Application object are described below:

Collections

Collection	Description
Contents	Contains all items that were appended to the application through script commands.
StaticObjects	Contains all objects that were appended to the application using the HTML <object> tag.

Methods

Method	Description
Contents.Remove	Deletes an item from the Contents collection.
Contents.RemoveAll()	Deletes all items from the Contents collection.
Lock	Prevents other users from modifying variables in the Application object.
Unlock	Enables other users to modify variables in the Application object (after being locked with the Lock method).

Events

Event	Description
Application_OnEnd	This event occurs when all user sessions have ended and the application is shut down.
Application_OnStart	This event occurs before the first new session is created (i.e., when the Application object is first referenced).
