This method sets the globally unique identifier (GUID) of the interface that defined the error.

Syntax 

HRESULT SetGUID( 
  REFGUID 
rguid
);

Parameters

rguid

[in] GUID of the interface that defined the error, or GUID_NULL if the error was defined by the operating system.

Return Value

If the method succeeds, the return value is S_OK.

If there is insufficient memory to complete the operation, the return value is E_OUTOFMEMORY.

Remarks

SetGUIDsets the GUID of the interface that defined the error. If the error was defined by the system, set SetGUIDto GUID_NULL.

This GUID does not necessarily represent the source of the error; however, the source is the class or application that raised the error. Using the GUID, applications can handle errors in an interface, independent of the class that implements the interface.

Example

Copy Code 
hr = CreateErrorInfo(&pcerrinfo);
pcerrinfo->SetGUID(IID_IHello);

Requirements

Header oaidl.h, oaidl.idl
Library oleaut32.lib, uuid.lib
Windows Embedded CE Windows CE 2.0 and later
Windows Mobile Windows Mobile Version 5.0 and later
