Hello Myron,
I don't understand exactly what your issue is here? WhatTheFont is a system used either through our site or our phone apps - I'm not sure how you're trying to implement it through CorelDraw, or implement CorelDraw through it?
Let us know if you have any other questions. Thanks for using MyFonts!
