SectionInformation Class [IIS 7 and higher]

IIS 7.0

Specifies override-mode and control-locking settings for a configuration section.

class SectionInformation : EmbeddedObject

This class contains no methods.

The following table lists the properties exposed by the SectionInformation class.

Name

Description

EffectiveOverrideMode

A read-only string value that specifies whether the current configuration section can effectively override its inherited settings. The possible values are listed later in the Remarks section.

To determine the value of EffectiveOverrideMode, IIS traverses up the inheritance hierarchy of configuration sections from the current section. It successively examines the OverrideMode property of each parent section until it reaches the overrideModeDefault attribute in the section schema definition. IIS calculates the EffectiveOverrideMode by logically combining the values that it encounters and considering their hierarchical ranking.

NoteNote:
overrideModeDefault is an optional attribute that contains the default lockdown state of a configuration section. The overrideModeDefault attribute for each configuration section is located in the corresponding section definition under <configSections> in the ApplicationHost.config file. If overrideModeDefault is missing, its value is "Allow". If "Allow" is specified, lower level Web.config files can override settings for the section; if "Deny" is specified, they cannot. The overrideModeDefault default for most IIS Web server sections is "Deny". The default for most ASP.NET and .NET Framework sections is "Allow", because these sections contain application-level settings.The overrideModeDefault attribute has no corresponding property in WMI. If you have appropriate permissions, you can edit the ApplicationHost.config file directly or access it programatically by using XML parsing or file access APIs.

IsLocked

A read-only boolean value. true if the current configuration section and its child elements cannot be modified; otherwise, false.

LockItem

A read/write boolean value. true if the current configuration section and its child elements are locked; otherwise, false. The default is false.

NoteNote:
Although the default is false, this property will return null when it is initially read. If you explicitly set this initial value to false, the property will still return null. However, if you set the initial value to true, the property will return true; if you then set the value to false, the property will explicitly return false. This behavior is due to a limitation in the WMI provider.

OverrideMode

A read/write string value that specifies whether lower level configuration files can override the settings in the current configuration section. The possible values are listed later in the Remarks section.

This class contains no subclasses.

Instances of this class are contained in the SectionInformation property of the ConfigurationSection class. All configuration section classes inherit the SectionInformation class as one of their properties.

The following table lists the possible values for the EffectiveOverrideMode property.

Keyword

Description

Allow

Lower level configuration files can override the settings in the current configuration section.

Deny

Lower level configuration files cannot override the settings in the current configuration section.

The following table lists the possible values for the OverrideMode property. The default is "Inherit".

Keyword

Description

Inherit

Lower level configuration files can or cannot override the settings in the current configuration section, depending on the combination of OverrideMode values that they inherit.

Allow

Lower level configuration files can override the settings in the current configuration section.

Deny

Lower level configuration files cannot override the settings in the current configuration section.

NoteNote:

The EffectiveOverrideMode property is useful in determining what the effective override mode for a configuration section is when the OverrideMode property is set to "Inherit".

The following example retrieves the SectionInformation properties for all configuration sections.

' Connect to the WMI WebAdministration namespace.
Set oWebAdmin = GetObject("winmgmts:root\WebAdministration")

' Retrieve configuration sections.
Set oConfigSections = oWebAdmin.ExecQuery( _
    "SELECT * FROM ConfigurationSection")

' Loop through the configuration sections.
For Each oConfigSection In oConfigSections
    iCounter = iCounter + 1

    ' Display the name of each configuration section and its location.
    WScript.Echo "[" & iCounter & "] " & oConfigSection.Path_.Class
    WScript.Echo "Location: " & oConfigSection.Location
    
    ' Display the SectionInformation property values.
    Set oConfigSectionInfo = oConfigSection.SectionInformation
    WScript.Echo "Effective Override Mode: " & _
        oConfigSectionInfo.EffectiveOverrideMode
    WScript.Echo "Is Locked: " & oConfigSectionInfo.IsLocked
    WScript.Echo "Is Present: " & oConfigSectionInfo.IsPresent        
    WScript.Echo "Lock Item: " & oConfigSectionInfo.LockItem            
    WScript.Echo "Override Mode: " & oConfigSectionInfo.OverrideMode
    WScript.Echo "------------------------------------------"
