Hi,

Here's a bit of code I use:

 Private Sub ShowReport_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnShowReport.Click

        Dim oReport As CrystalDecisions.CrystalReports.Engine.ReportDocument
        oReport = SetUpReport(txtStartDate.Text, txtEndDate.Text)

        'CView is CD Web reportviewer 
        CView.ReportSource = oReport
        CView.Visible = True
    End Sub

    Private Function SetUpReport(ByVal StartDate As String, ByVal EndDate As String) As CrystalDecisions.CrystalReports.Engine.ReportDocument

        Dim BL As New LVBLayer.CInfo
        Dim ds As DataSet

        Dim SD As Date = CType(StartDate, Date)
        Dim ED As Date = CType(EndDate, Date)
        ds = BL.GetInterceptsForPeriod(SD, ED)
        Dim oReport As New CrystalDecisions.CrystalReports.Engine.ReportDocument
        With oReport
            .Load("report.rpt")
            .SetDataSource(ds)
            .SetParameterValue("StartDate", SD)
            .SetParameterValue("EndDate", ED)
        End With
        Return oReport
    End Function

SetUpReport is only a seperate function because it's also used when producing PDF / Excel versions of the report. The dataset for the report is selected based on the input values. I'm only passing these to the Crystal report document because they are used in the report heading.

BTW, the .NET template you were attempting to add is only the cut-down Crystal reports designer that is provided with Visual Studio. If you have the full version of Crystal Decisions to create the .RPT file then you have no real need for it.

HTH,
