ConfigurationSection.GetAllowDefinition Method [IIS 7 and higher]

Article
07/13/2012

Retrieves the allowDefinition attribute for a configuration section.

Syntax

ConfigurationSection.GetAllowDefinition AllowDefinition

ConfigurationSection.GetAllowDefinition(AllowDefinition);

Parameters

Name	Definition
AllowDefinition	A string variable that receives the allowDefinition attribute that the GetAllowDefinition method returns. The possible attribute values are listed later in the Remarks section.

Return Value

This method does not return a value.

Remarks

allowDefinition attributes specify where in the configuration hierarchy values may be set for a given configuration section. These attributes are specified in the <configSections> section of the ApplicationHost.config file.

Because GetAllowDefinition is a static method, you should call it by getting a class object, as in the following example.

' Correct syntax:
Set oAnonAuth = oWebAdmin.Get("AnonymousAuthenticationSection")
oAnonAuth.GetAllowDefinition strAnonAuthAllowDefinition

The following syntax fails because it tries to call GetAllowDefinition on a concrete instance of the Site class. The call to the method will cause an "SWbemObjectEx: Not found" error.

' Incorrect syntax:
Set oSite = oWebAdmin.Get("Site.Name='Default Web Site'")
oSite.GetSection "AnonymousAuthenticationSection", oAnonAuth
oAnonAuth.GetAllowDefinition strAnonAuthAllowDefinition

The following table lists the possible values for the allowDefinition attribute.

Keyword	Description
Everywhere	The section can be set anywhere in the hierarchy.
MachineOnly	The section can be set only in the Machine.config file. Note: The default location for the Machine.config file is %systemroot% Microsoft.NET\Framework\<version>\config\.
MachineToWebRoot	The section can be set only in the Machine.config file or the root Web.config file. Note: The default location for the root Web.config file is %systemroot% Microsoft.NET\Framework\<version>\config\.
AppHostOnly	The section can be set only in the ApplicationHost.config file.
MachineToApplication	The section can be set only at the global level. For .NET Framework sections, the global level is the root Web.config or Machine.config file; for IIS sections, it is the ApplicationHost.config file; and for applications, it is the Web.config file for the root application.

Example

The following example displays the allowDefinition attribute for the Anonymous authentication configuration section.

' Get the WebAdministration namespace.
Set oWebAdmin = GetObject( _
    "winmgmts:root\WebAdministration")

' Get the AnonymousAuthenticationSection.
Set oAnonAuth = oWebAdmin.Get( _
    "AnonymousAuthenticationSection")

' Get the allowDefinition attribute.
oAnonAuth.GetAllowDefinition strAnonAuthAllowDefinition

' Display the allowDefinition attribute.
WScript.Echo _
    "Anonymous Authentication Allow Definition: " & _
        strAnonAuthAllowDefinition
