Parameters

Return Value

Type: System.Int32
If successful, returns S_OK; otherwise, returns an error code.

Implements

IVsLanguageContextProvider.UpdateLanguageContext(UInt32, IVsTextLines, array<TextSpan[], Object)

Remarks

The given object can be queried for the IVsUserContext interface by casting it to the IVsUserContext interface: IVsUserContext pContext = ptr as IVsUserContext.

The base method calls the other LanguageService.UpdateLanguageContext and always returns S_OK.
