Load Reports with saved data twice not refresh data

Hi,

I have a program that load and print rpt file with saved data inside. I'm usign VS2010 with CR2010. I load and print report with:

rpt.Load(strFileName))

rpt.PrintToPrinter(Copies, True, 0, 0)

If I load and print reports, modify data inside and load and print again the second action use  the data of first load.

If I use the follow instruction all work.

rpt = New ReportDocument

rpt.Load(strFileName))

rpt.PrintToPrinter(Copies, True, 0, 0)

Seems the load function not refresh data inside if I load the same report.

Are there a property to force this without create a new object every time ?

Thanks Filippo
