selection formula and parameter to create Crystal Report

Hello,
I have the following situation.
I am developing a web application to create Crystal Reports using CrystalReportViewer control.
Platform: ASP.NET (2.0), Code Behind: VB.NET, Database: Oracle 10G
In the form, I enter the search criteria and create a selection formula as well as parameter for the Crystal report. I know how to pass this selection formula and parameter in VB 6.0 but not in asp.net. Therefore, I am not looking for the answer in vb 6.0.
My question is after I creat the selection formula from the form's data entry, how can I call/pass this selection formula to create the crystal report using the crystal report viewer control.
Does anyone have a complete sample code which shows step by step of creating crystal reports using asp.net (vb.net) ?

For example, my selection formula is: strSelectionFormula (whatever is there)
my parameter is: strParam (whatever is there)
Next, I did the following lines
        Dim Report1 As ReportDocument
        Report1 = New ReportDocument()
        Report1.Load(Server.MapPath("CrystalReport\Sample.rpt"))

Then I do not know what to do. My crystal report viewer control is in the same page of web form. I am not calling a different page using response.redirect (reportpage.aspx). I hope my question is clear.

Thanks a ton in advance,
mamun

Here is a tutorial for VS2005.  I believe the same ideas will work with VS2008.  I think the parameter passing starts on page 141.  Check the table of contents.

Try This Code

Partial Class MyReport
    Inherits System.Web.UI.Page
 
    Private customerReport As ReportDocument
 
    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init
 
        ConfigureCrystalReports()
 
    End Sub
 
    Private Sub ConfigureCrystalReports()
 
        Dim Report1 as  ReportDocument()
        Report1=New ReportDocument()
        customerReport.Load(Server.MapPath("CrystalReport\Sample.rpt"))
                    CrystalReportViewer1.SelectionFormula = strSelectionFormula
         CrystalReportViewer1.ReportSource = customerReport
 
    End Sub
 
End Class
