) : int

Parameters

  • dwHint
    Type: System.UInt32
    [in] Value indicating whether this is a typical idle-time update of the context bag or a request for F1 Help. For a list of dwHint values, see LanguageContextHint.
  • pUC
    Type: System.Object
    [in, out] Pointer to the context bag on the Visual Studio core text editor.

Return Value

Type: System.Int32
If the method succeeds, it returns S_OK. If it fails, it returns an error code.

Remarks

COM Signature

From textmgr.idl:

HRESULT IVsLanguageContextProvider::UpdateLanguageContext(
   DWORD dwHint, 
   IVsTextLines *pBuffer, 
   TextSpan *ptsSelection
);

UpdateLanguageContext return values:

S_OK: the implementer has added whatever context should be added.

Any other success code: forbidden (caller will assert).

Any failure code: means the implementer is "passing" on this opportunity to provide context and the text editor will fall back to other mechanisms.
