dim myCr as rptMyReport (name of my crystal reports, includes rptHeader)

dim rptDoc as ReportDocument

dim ds as new DataSet



connect to sql stored proc.. here returns DataSet



ds = .... call to function



............



rptDoc = myCr.OpenSubReport("rptHeader")

rptDoc.SetParameterValue("DeliveryV1", "123456")

rptDoc.database.tables(0).setdatasource(another function returns ds)

myCr.setdatasource(ds.tables("xx"))
