Re: Accessing XMP files

Inder, I have read the SDK documentation.  I am trying to understand how I can read the data elements within structures within an array.  The screenshot, below, shows you the structure I am dealing with. I am using the XMP SDK with C++.

Thank you for your assistance,

Bill Scully
