Need to stay in the same screen till calculation process yet to be completed?

Hi Team,
I am running the calculation in one application in that “Calculation process completed” message need to show so far i need to stay in that screen itself after showing that message i need to take the screenshot,save in local system and send a mail to the corresponding person

A post was merged into an existing topic: After clicking the button calculate process started at the button will be blur then again that button will be in clear visible at the time “Calculation process completed”
