I use this method:

I used this code to pass values to parameters:

    Private Sub SetParameters()
        Dim objParameterFieldDefinition As CrystalDecisions.CrystalReports.Engine.ParameterFieldDefinition
        Dim objParameterValues As CrystalDecisions.Shared.ParameterValues
        Dim objParameterDiscreteValue As CrystalDecisions.Shared.ParameterDiscreteValue

        'Set the parameter name on the next line
        objParameterFieldDefinition = rptReport.DataDefinition.ParameterFields.Item("pMgmtFees")
        objParameterValues = New CrystalDecisions.Shared.ParameterValues
        objParameterDiscreteValue = New CrystalDecisions.Shared.ParameterDiscreteValue
        'Set the parameter value on the next line
        objParameterDiscreteValue.Value = Me.mdecMgmtFees
        objParameterValues.Add(objParameterDiscreteValue)
        objParameterFieldDefinition.ApplyCurrentValues(objParameterValues)

        'Set the parameter name on the next line
        objParameterFieldDefinition = rptReport.DataDefinition.ParameterFields.Item("pIncentiveFees")
        objParameterValues = New CrystalDecisions.Shared.ParameterValues
        objParameterDiscreteValue = New CrystalDecisions.Shared.ParameterDiscreteValue
        'Set the parameter value on the next line
        objParameterDiscreteValue.Value = Me.mdecIncentiveFees
        objParameterValues.Add(objParameterDiscreteValue)
        objParameterFieldDefinition.ApplyCurrentValues(objParameterValues)

     End Sub
