The ProvideLanguageEditorOptionPageAttribute type exposes the following members.

Constructors

	Name	Description

Properties

	Name	Description
	LanguageName	Gets the name of the language.
	PageGuid	Gets the GUID of the option page.
	PageNameResourceId	Gets the name resource ID of the page. (Inherited from ProvideOptionDialogPageAttribute.)
	PageType	Gets the type of the page. (Inherited from ProvideOptionDialogPageAttribute.)
	TypeId	Gets the current instance of this attribute. (Inherited from RegistrationAttribute.)

Methods

	Name	Description
	Equals	Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Returns the hash code for this instance. (Inherited from Attribute.)
	GetPackageRegKeyPath	Gets the registry path (relative to the registry root of the application) of the VSPackage. (Inherited from RegistrationAttribute.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	IsDefaultAttribute	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.)
	Match	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Register	Creates all the registry keys and entries as specified by the class constructor. (Overrides RegistrationAttribute.Register(RegistrationAttribute.RegistrationContext).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Unregister	Removes all of the registry keys and entries. (Overrides RegistrationAttribute.Unregister(RegistrationAttribute.RegistrationContext).)

Explicit Interface Implementations

	Name	Description
	_Attribute.GetIDsOfNames	Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.)
	_Attribute.GetTypeInfo	Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.)
	_Attribute.GetTypeInfoCount	Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.)
	_Attribute.Invoke	Provides access to properties and methods exposed by an object. (Inherited from Attribute.)

Remarks

This information is stored in the registry key <RegistrationRoot>\Languages\Language Services\[language]\EditorToolsOptions, where [language] is the name of the language.

Under EditorToolsOptions is a tree of pages and sub-pages that can nest any number of levels. These pages correspond to the options pages displayed in the Visual Studio Tools Options for editors (where a tree of option pages is displayed under the language name, each page containing appropriate options).

Each key in this option page list contains a resource id or literal string containing the localized name of the page. This is what is actually shown in the Tools Options dialog. In addition, it also contains a package GUID and optionally a GUID of an option page.

If there is no option page GUID, then the key is considered to be a node in the tree of options and has no associated page. Otherwise, the key is a leaf in the tree, and its option page will be shown.

There can be multiple instances of this attribute, and each instance specifies a node or a property page. The attributes can appear in any order. If the property page GUID is specified then a property page is registered, otherwise it is a node that is registered.

The following user-defined attributes are used for language services:

Attribute	Description
ProvideLanguageServiceAttribute	Registers the language service with Visual Studio and specifies which features are supported.
ProvideLanguageExtensionAttribute	Associates a file extension with the language service.
ProvideLanguageEditorOptionPageAttribute	Specifies a property node or page for the Options dialog box specific to the language service.
ProvideLanguageCodeExpansionAttribute	Specifies location information to support code snippets in the language service.
ProvideServiceAttribute	Registers a language service as a Visual Studio service. All services supplied in managed code use this attribute.

Notes to Implementers

This attribute class cannot be inherited from so there is nothing to implement.

Notes to Callers

This attribute class is typically applied to your primary VSPackage class, although it can appear on any class. This attribute class can appear multiple times and in any order, once for each property page and node in the property page tree.

Examples

This example shows how this user-defined attribute is used to register two property pages ("General" and "Indent") and a property page node ("Formatting") that contains the "Indent" property page. Note how the second parameter to the constructor specifies the position in the registry relative to the node.

Note

Visual C# allows for a shorthand form of a user-defined attribute by dropping the "Attribute" part of the name. This shorthand form is used in this and all other examples throughout this class.
