IAMExtendedErrorInfo Interface

The IAMExtendedErrorInfo interface is used to obtain error information. This interface is not implemented by any default components in DirectShow.

In addition to the methods inherited from IDispatch, the IAMExtendedErrorInfo interface exposes the following methods.

Method Description
get_ErrorCode Retrieves the current error code.
get_ErrorDescription Retrieves the error description.
get_HasError Queries whether an error occurred.

Requirements

Header: Include Qnetwork.h.

Library: None.

To define the interface identifier, include the header file Initguid.h before Qnetwork.h, but after Dshow.h and other header files:

#include <dshow.h>
#include <initguid.h>
#include <qnetwork.h>
  • Note   Make sure that Initguid.h is included only once in your project. Otherwise, you will receive linker errors for duplicate GUID values.
