class ATL_NO_VTABLE ISupportErrorInfoImpl :
public ISupportErrorInfo
Parameters
- piid
A pointer to the IID of an interface that supports IErrorInfo.
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>
