)

Parameters

languageService
Type: System::Object^

[in] This is either a string containing a GUID or a type representing the class that implements the language service. The language service GUID is derived from this string or type.

languageName
Type: System::String^

[in] The name of the language. This name is used in the registry for registry key and entry names.

languageResourceId
Type: System::Int32

[in] The resource ID for the localized version of the language name. This is used to present the language name in dialog boxes and other user interface elements.

languageIdentifier
Type: System::String^

[in] A string containing an identifier specific to the language that is used to mark and identify code snippets.

pathToSnippetIndexFile
Type: System::String^

[in] A string containing the path to the code snippets index file for the language.

The following registry layout shows where each of the required parameters is used.

Copy 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[X.Y]\Languages\

      [languageName]\
        (Default) = reg_sz: [languageService]
         DisplayName  = reg_sz: [languageResourceId]
         IndexPath    = reg_sz: [pathToSnippetIndexFile]
         LangStringID = reg_sz: [languageIdentifier]
         Package      = reg_sz: [Package GUID]

The [Package GUID] value is automatically obtained from the class that implements the IVsPackage interface in the assembly.

In addition to the required parameters listed in the Parameters section, the constructor also accepts optional named parameters after the required parameters. This is a special form supported only in user-defined attributes. These named parameters correspond to the public properties on this class that have both get and set operators.

For details on how the snippet index file is created and used, see Support for Code Snippets (Managed Package Framework).
