Thanks  Bill

 QSettings is working fine in my application according to my senario..

And i have one more doubt  ,Will it increase the Application Size ?,where the saved datas are stored..

Then i tried with  local file,i created one  text file and  tried to save the contents there.. But application is crashing ,ok i will solve that problem..

My only thing whatever i saved ,that datas will be displaying ,once i login in my application.


Thanks

Theoretically it should be faster than QSettings. Usually it is,
especially if you index the right fields. Generally, when trying
something like this I write a bunch of unit tests, or a test
application, and run a comparison run between the two, get timings, etc.
