The ILanguageComponentType interface is implemented on LanguageComponentType objects. It provides methods that define the language of the stream content. Not all streams have a language component.
In addition to the methods inherited from IDispatch and IComponentType, the ILanguageComponentType interface exposes the following methods.
| Method | Description | 
| get_LangID | Retrieves the language of the stream content. | 
| put_LangID | Sets the language of the stream content. |
