Thanks for the help ,It is working fine , what I notice If i use your idea and put a variable of Today's date , It works fine now but later or next day it shows me error like data has been not loaded. Can you please tell me how to fetch data from a particular date to today , as I am looking to create an application which fetch data until today. But I don't wana do all the stuff , like go to QV source every time , select query there ,copy code and paste it here, If this I need to do , this is not a real time application.
Thanks a lot, your suggestion are really helpful. What i Noticed , we must run first QVSource and then run authenticate after that if we run the script it loads the data from Google Analytics Source. So Now the question is Do I need to run always QVSource manually or there is any way which makes qv source always run at back end , for this time I am using a desktop application , May be on server side , If i run QVSource once so it will always run at back end. Please correct me if I am on wrong Path.
