Parameters

dwHint
Type: System.UInt32
[in] A set of flags from the LanguageContextHint enumeration.

buffer
Type: Microsoft.VisualStudio.TextManager.Interop.IVsTextLines
[in] The IVsTextLines object holding the source.

ptsSelection
Type: array<Microsoft.VisualStudio.TextManager.Interop.TextSpan[]
[in] A single TextSpan object describing the selected range of text (or the current caret position).

ptr
Type: System.Object
[in] An IVsUserContext object that is to be updated.

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.
