  Hi,
  
  We have our own preview form to display reports. With this preview form, users can simply show or hide some image of a invoice for exemple.
  
  To show the report at the first time I call PrepareReport(True). After the user hide the image, so I must recall PrepareReport(True).
  
  When I call PrepareReport a second time, the error "DataSet '''' does not exist" appears.
  
  Thanks for your help.

  
  It's not possible to call PrepareReport two times ?

  I don't think so.
  Can't you display a parameters dialog box to the user before generating it, so you make the controls invisible before calling preparereport()?

  No the buttons are in the toolbox of the preview form. So I must recreate the report when a changed is made.
  Why this error message appears?

  use PrepareReport(False) instead.
