Hlw Sir ,
I have compile your code successfully but write now i track the application and also get the start time and duration but i need the file name of the particular application like that when we open Acrobat Reader application and then open any pdf in that like sample.pdf .
then we need to track that pdf name which is not able to track now .

So can you please give some tips to how we perform that.
