Reports 3.0.5 : Parameter Window -> Hidden!

I have a report with a parameter called by a form, this form create a parameter list
that pass to the report. When the report is executed, the parameter form window appear
with the value of the parameter passed by the form.

I want to eliminate the parameter window if there are any parameter passed, but how?

Thanks,
(excuse my English)
