Unable to get face identity in Solidworks API

In solidworks API I am not able to get face identity (Part). Whenever I select any face and get "Measure" from "evaluate" it shows "face1" for any face selected first. I want to know the exact face identity (eg. face1@sketch1) like this so that I can use it in macro. Plz help

Thank You.
