Application Object

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

Application.Contents Collection

Application.Content Collection adds or sets the value of an item of the Contents collection of Application object through script commands.

Syntax:

Application.Contents( Key)

 Or in an ASP file.  Imply

<% Application.Contents( Key) %>

Parameters:

Key

The parameter "Key" is used to specify the name of the item to retrieve.

Remarks:

The Contents collection contains only the list of items that have been declared in application scope using script commands not the <OBJECT> tags. Therefore both an application declaration and objects created by using the Server.CreateObject are contained in the Contents Collection

The Contents collection can be used to obtain the list of items or a particular item that have been declared in application scope.

But the items in the Contents collection can only be removed from the collection by using the Remove and RemoveAll methods.

The Contents Collection is in the form of collection, the values of the keys of the cotents collection should be retrieved using a for each element loop in order to get the name of the element. Or using a for index loop is the key is predetermined..

Examples:

  • Use Application.Contents to retrieve the value of item

    ASP script command:

    <%
    Application("App1") = "App1value"
    Application("App2") = "App2value"
    Application("App3") = "App3value"
    For Each element in Application.Contents
    Response.write element & " = " & Application(element) & "<br>"
    Next
    For itemno = 1 to Application.Contents.Count
    Response.Write CStr(itemno) & " = " & _
    Application.Contents(itemno) &  "<br>"
    Next
    %>

    HTTP response output:

    App1 = App1value<br>
    App2 = App2value<br>
    App3 = App3value<br>
    1 = App1value<br>
    2 = App2value<br>
    3 = App3value<br>

    HTML web page ouput:

    App1 = App1value
    App2 = App2value
    App3 = App3value
    1 = App1value
    2 = App2value
    3 = App3value

Application.StaticObjects Collection

Application.StaticObjects Collection collects all objects added to the session through the <OBJECT> tag within the Application scope

Syntax:

Application.StaticObjects( Key)

 Or in an ASP file. Imply

<% Application.StaticObjects( Key) %>

Parameters:

Key

The parameter "Key" is used to specify the name of the item to retrieve.

Remarks:

The StaticObjects collection contains only the list of items that have been declared in application scope using <OBJECT> tags not the script commands. Therefore both an application declaration and objects created by using the Server.CreateObject are contained in the Contents Collection not in StaticObject collection.

The StaticObjects collection can be used to obtain the list of items or a particular item that have been declared in application scope.

The StaticObjects Collection is in the form of collection, the values of the keys of the StaticObjects  collection should be retrieved using a for each element loop in order to get the name of the element.
