how to change datasource of crystal report using VB6.0?

I was able to show the preview base on my parameter but when i attempt to change my database using CRViewer.Database i got an error "INVALID use of property" something like that.

my code is

With Report
.Database = "\\Server\Biboy System\RSIS\CheckDelPerm.mdb"
.RecordSelectionFormula = "{Check_Delivery.DR_Number} = '" + dr_number.Text + "'"
.PaperOrientation = crPortrait
End With
