Error and Success Codes

Microsoft® DirectX® Transform returns error and success notifications (return codes) to applications in the form of HRESULT values. For more information, see the HRESULT documentation in the Component Object Model (COM) section of the Platform SDK. The Platform SDK also includes information on how to use the FAILED and SUCCEEDED macros to test return values.

DirectX Transform uses facilities of Microsoft Internet Explorer 4.x or later to load images and handle error codes during image loading. For details on these error codes, consult the Internet Explorer image load documentation.
