dwReserved
Type: System.UInt32

Unused parameter. Must be set to nulla null reference (Nothing in Visual Basic).

Pointer to the context bag on the Visual Studio core 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 IVsTextMarkerContextProvider::UpdateContextForMarker(
   DWORD dwReserved,
   IVsUserContext *pUC
);

The core text editor calls IVsTextMarkerContextProvider.UpdateContextForMarker at the same time that it updates other context. The TextMarker object should implement this method and add a keyword and/or attributes to the given context bag that is specific to the text marker (probably a squiggly).

If a marker has the MV_CONTEXT_CONTRIBUTION_FOR_BODY style set, its client will be QueryInterfaced for this interface.
