Application Object

One of the key functions of Application Object is the application control on the server.

Application_OnStart Event

Application_OnStart Event occurs on the start of the Application before the first Session_OnStart event. Available objects are Application Object and Server Object built-in objects.

Syntax:

<SCRIPT LANGUAGE=ScriptLanguage RUNAT=Server>
Sub Application_OnStart
    ...Script...
End Sub
</SCRIPT>

 Or in Global.asa. Imply

<SCRIPT LANGUAGE=ScriptLanguage RUNAT=Server>
Sub Application_OnStart
    ...Scripts...
End Sub
</SCRIPT>

Parameters:

ScriptLanguage

The parameter "ScriptLanguage" is used to specify the scripting language used in writing the event script.

Script

The parameter "Script" is the program written by the scripting language for the script interpreter of the Web Server.

Remarks:

The scipting language can be any supported language, such as VBScript or JScript. When more than one event using the same scripting language, all event sub-rountine can be combined under a single set of <SCRIPT> tags.

 In the Application_OnStart script, only the Application Object and Server Object built-in objects are available. Referencing the Session Object, Request Object, or Response Object objects in the Application_OnStart event script will cause an error.

Since the Application_OnStart script can be called only once by the first session when the application start, Application.Lock and Application.Unlock methods are not needed, .

Examples:

  • Use Application_OnStart to specify application start

    ASP script command:

    <SCRIPT LANGUAGE=ScriptLanguage RUNAT=Server>
    Sub Application_OnStart
        Application("AppStart") = 1
    End Sub
    </SCRIPT>

Application_OnEnd Event

Application_OnEnd Event occurs on the end of the Application after all the Session_OnEnd event. Available objects are Application Object and Server Object built-in objects.

Syntax:

<SCRIPT LANGUAGE=ScriptLanguage RUNAT=Server>
Sub Application_OnEnd
    ...Script...
End Sub
</SCRIPT>

 Or in Global.asa. Imply

<SCRIPT LANGUAGE=ScriptLanguage RUNAT=Server>
Sub Application_OnEnd
    ...Scripts...
End Sub
</SCRIPT>

Parameters:

ScriptLanguage

The parameter "ScriptLanguage" is used to specify the scripting language used in writing the event script.

Script

The parameter "Script" is the program written by the scripting language for the script interpreter of the Web Server.

Remarks:

The scipting language can be any supported language, such as VBScript or JScript. When more than one event using the same scripting language, all event sub-rountine can be combined under a single set of <SCRIPT> tags.

In the Application_OnEnd script, only the Application Object and Server Object of built-in objects are available, however the Server.MapPath method is not available.

And by default, Application_OnEnd runs as the Anonymous User, as defined for the application. If there isn't an Anonymous user, or the Logon for the Anonymous user fails, the OnEnd function will not be called, and an event will be logged.

Examples:

  • Use Application_OnEnd to specify application end

    ASP script command:

    <SCRIPT LANGUAGE=ScriptLanguage RUNAT=Server>
    Sub Application_OnStart
        Application("AppStart") = 1
    End Sub
    Sub Application_OnEnd
        Application("AppStart") = 0
    End Sub
    </SCRIPT>
