ICreateErrorInfo::SetGUID method (oaidl.h)

Sets the globally unique identifier (GUID) of the interface that defined the error.

Syntax

HRESULT SetGUID(
  [in] REFGUID rguid
);

Parameters

[in] rguid

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

Return value

This method can return one of these values.

Return code Description
S_OK
Success.
E_OUTOFMEMORY
Insufficient memory to complete the operation.

Remarks

This method sets the GUID of the interface that defined the error. If the error was defined by the system, set ICreateErrorInfo::SetGUID to 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.

Use of this function is demonstrated in the file Main.cpp of the COM Fundamentals Hello sample.
