ConfigurationSection.SetAllowDefinition Method [IIS 7 and higher]

Sets the allowDefinition attribute for a configuration section.

Syntax

ConfigurationSection.SetAllowDefinition(AllowDefinition)

ConfigurationSection.SetAllowDefinition(AllowDefinition);

Parameters

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 SetAllowDefinition 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.SetAllowDefinition "MachineOnly"

The following syntax fails because it tries to call SetAllowDefinition 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.SetAllowDefinition "MachineOnly"

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 sets 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")

' Set the AllowDefinition attribute.
oAnonAuth.SetAllowDefinition "MachineToApplication"
