<h2>Application Object</h2>
<p>An application on the Web may be a group of ASP files. The ASP files work together to perform some purpose.
The Application object in ASP is used to tie these files together.</p>
<p>The Application object is used to store
and access variables from any page, just like the Session object. The difference
is that ALL users share one Application object, while with Sessions there
is one Session object for EACH user.</p>
<p>The Application object should hold information that will be used by many
pages in the application (like database connection information). This means that
you can access the information from any page. It also means that you can change
the information in one place and the changes will automatically be reflected on
all pages.</p>
<p>The Application object's collections, methods, and events are described
below:</p>
<h3>Collections</h3>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<th width="30%" align="left">Collection</th>
<th width="70%" align="left">Description</th>
</tr>
<tr valign="top">
<td><a href="coll_contents_app.asp">Contents</a></td>
<td>Contains all the items appended to the application
through a script command</td>
</tr>
<tr valign="top">
<td><a href="coll_staticobjects_app.asp">StaticObjects</a></td>
<td>Contains all the objects appended to the application with the HTML <object> tag</td>
</tr>
</table>
<h3>Methods</h3>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<th width="30%" align="left">Method</th>
<th width="70%" align="left">Description</th>
</tr>
<tr>
<td valign="top"><a href="met_contents_remove_app.asp">Contents.Remove</a></td>
<td valign="top">Deletes an item from the Contents collection</td>
</tr>
<tr>
<td valign="top"><a href="met_contents_removeall_app.asp">Contents.RemoveAll()</a></td>
<td valign="top">Deletes all items from the Contents collection</td>
</tr>
<tr>
<td valign="top"><a href="met_lock_unlock.asp">Lock</a></td>
<td valign="top">Prevents other users from modifying the variables in the
Application object</td>
</tr>
<tr>
<td valign="top"><a href="met_lock_unlock.asp">Unlock</a></td>
<td valign="top">Enables other users to modify the variables in the Application object
(after it has been locked using the Lock method)</td>
</tr>
</table>
<h3>Events</h3>
<table class="ex" cellspacing="0" border="1" width="100%" cellpadding="3">
<tr valign="top">
<th width="30%" align="left">Event</th>
<th width="70%" align="left">Description</th>
</tr>
<tr valign="top">
<td><a href="ev_app_onend_onstart.asp">Application_OnEnd</a></td>
<td>Occurs when all user sessions are over, and the application ends</td>
</tr>
<tr valign="top">
<td><a href="ev_app_onend_onstart.asp">Application_OnStart</a></td>
<td>Occurs before the first new session is created (when the Application object is first referenced)</td>
</tr>
