I have created my reports using crystal reports 8 and I don't want to change them or redesign them. All I need to do is to call them in .NET as I used to do in VB6. In short, I used to design this reports in Crystal Reports and call them using the following code:

cr.ReportFileName = "????"
cr.Action = 1

How do I acheive the same functionality in VB.NET???
