Remarks
The ISupportErrorInfo Interface ensures that error information can be returned to the client. Objects that use IErrorInfo must implement ISupportErrorInfo.
Class ISupportErrorInfoImpl provides a default implementation of ISupportErrorInfo and can be used when only a single interface generates errors on an object. For example:
class ATL_NO_VTABLE CMySuppErrClass :
public CComObjectRootEx<CComSingleThreadModel>,
public CComCoClass<CMySuppErrClass, &CLSID_MySuppErrClass>,
public ISupportErrorInfoImpl<&IID_IMySuppErrClass>,
public IDispatchImpl<IMySuppErrClass, &IID_IMySuppErrClass, &LIBID_NVC_ATL_COMLib, /*wMajor =*/ 1, /*wMinor =*/ 0>
