[ASP] สอบถามการรับ-ส่งค่า parameter จาก asp ไปยัง Crystal Report จะใช้ฟังก์ชั่นอะไรในการส่งครับ

Set session("oRpt") = session("oApp").OpenReport(path &  reportname & ".rpt", 1)
session("oRpt").DiscardSavedData
selection_formula = "{table.fields} =  '"&trim(ค่าตัวแปร)&"'"
session("oRpt").RecordSelectionFormula = cstr(selection_formula)
set session("ParamCollection") = Session("oRpt").Parameterfields         '*** ตรงนี้ครับ ***'

Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared
 
    Private Report As New ReportDocument()

    Protected Sub Page_Init(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Init

        Dim path As String = Server.MapPath("file_recycle_bin")

         Dim reportLocation As String = Server.MapPath("report/price.rpt")
              With Report
            .Load(reportLocation)
            .SetDataSource(Session("dtM"))
            .SetParameterValue("SDATE", Session("SDATE"))
            .SetParameterValue("HEAD_TEXT", Session("HEAD_TEXT"))
            .SetParameterValue("USER", Session("USER_NAME"))
                  End With
