Button value is 0 and when page Shows Progress bar set on 100

I searched in Google for This Problem But cant Find appropriate Solution

You might want to have a look at QProgressDialog. It's a dialog pre-made for exactly that purpose.

The main problem with these kinds of things is knowing how long it takes. Either you show the progress based on a known set of steps or based on a time estimate (not really recommended as it depends on many factors). But that pre-made dialog definitely takes a way some of the pain.
