The parameter argument depends of course on the application.
If "authorized" is a valid parameter, to eg open "newapp" in a special mode and nothing else is required, than your string should work.
I'm not sure what "and if I read in newapp.exe then I should be able see the string "authorized". " means.
Why don't you simply try it out. If you do not want to do this from your database use cmd.exe and enter
c:\newapp.exe /authorized
at the prompt.
