title: Lock rptdesign file
body: <p>I am trying to find out if it is possible to lock an rptdesign file.</p>
  
  <p>The idea is to run a report as a service, but without being able to change the default parameters. I know I could just hide the parameter window but still the user could edit the rptdesign file and hard code new values.</p>
  
  <p>Does anyone has any previous experience with this?</p>
  
  <p>Is it possible to make an rptdesign file non-editable?</p>
