Gets extended information for the property.

Syntax

HRESULT GetExtendedInfo ( 
   REFGUID* guidExtendedInfo,
   VARIANT* pExtendedInfo
);

int GetExtendedInfo ( 
   ref Guid guidExtendedInfo,
   out object pExtendedInfo
);

Parameters

guidExtendedInfo
[in] GUID that determines the type of extended information to be retrieved. See Remarks for details.

pExtendedInfo
[out] Returns a VARIANT (C++) or object (C#) that can be used to retrieve the extended property information. For example, this parameter might return an IUnknown interface that can be queried for an IDebugDocumentText2 interface. See Remarks for details.

Return Value

If successful, returns S_OK; otherwise returns error code. Returns S_GETEXTENDEDINFO_NO_EXTENDEDINFO if there is no extended information to retrieve.

Remarks

This method exists for the purpose of retrieving information that does not lend itself to being retrieved by calling the GetPropertyInfo method.

The following GUIDs are typically recognized by this method (the GUID values are specified for C# since the name is not available in any assembly). Additional GUIDs can be created for internal use.

Name GUID Description
guidDocument {3f98de84-fee9-11d0-b47f-00a0244a1dd2} Returns an IUnknown interface to the document. Typically, the IDebugDocumentText2 interface can be obtained from this IUnknown interface.
guidCodeContext {e2fc65e-56ce-11d1-b528-00aax004a8797} Returns an IUnknown interface to the document context. Typically, the IDebugDocumentContext2 interface can be obtained from this IUnknown interface.
guidCustomViewerSupported {d9c9da31-ffbe-4eeb-9186-23121e3c088c} Returns a string containing the CLSID of a custom viewer, typically implemented by an expression evaluator.
guidExtendedInfoSlot {6df235ad-82c6-4292-9c97-7389770bc42f} Returns a 32-bit number representing the desired slot number if this property represents a managed code local address.
guidExtendedInfoSignature {b5fb6d46-f805-417f-96a3-8ba737073ffd} Returns a string containing the signature of the variable associated with the property object.
