How could I load parameter values for a CR from VB.NET?

[Tazyoglu]

I have a parameterize report and I want to use this report in a .NET project but I've got an error. My report has only one parameter, pmUUID, integer type.

This is the VB.NET code:

Private Sub Page_Init(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Init

Dim paramFields As New CrystalDecisions.Shared.ParameterFields()
Dim paramField As New CrystalDecisions.Shared.ParameterField()
Dim discreteVal As New CrystalDecisions.Shared.ParameterDiscreteValue()
Dim rangeVal As New CrystalDecisions.Shared.ParameterRangeValue()
Dim x As Integer

InitializeComponent()

paramField.ParameterFieldName = "pmUUID"

discreteVal.Value = 1

paramField.CurrentValues.Add(discreteVal)

paramFields.Add(paramField)

CrystalReportViewer1.ParameterFieldInfo = paramFields

CrystalReportViewer1.ParameterFieldInfo = paramFields

CrystalReportViewer1.ReportSource = "C:\\Work\\ASPXTest\\rptTest.rpt"

CrystalReportViewer1.DataBind()

End Sub

and this is the error:

Server Error in '/ASPXTest' Application.
