crystal report parameter problem

[rahman86]

hello everyone.

I have a program that should display report let say from a date to date. but i am using string compare and not date compare. what is my problem is it is not displaying the correct output and always shows a dialog box that request parameter.
-how do i make so that the default parameter box not showing?
-how do i make the report display the output correctly?
-the connections always show "logon failed" and need to be refreshed everytime i want to display the report.

so here is my code

Imports CrystalDecisions.CrystalReports.Engine
Imports CrystalDecisions.Shared

Public Class BKCictSpecsReport

    Private Sub VotSubmitBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles VotSubmitBtn.Click
        '
        Dim repDoc As New BkcictSpecCR 'Result is the report doc .rpt

        Dim crParameterFieldDefinitions As ParameterFieldDefinitions
        Dim crParameterFieldDefinition As ParameterFieldDefinition
        Dim crParameterValues As New ParameterValues
        Dim crParameterDiscreteValue As New ParameterDiscreteValue

        crParameterDiscreteValue.Value = BKCICTDatePicker1.Text
        crParameterFieldDefinitions = _
            repDoc.DataDefinition.ParameterFields
        crParameterFieldDefinition = _
            crParameterFieldDefinitions.Item("fromDate")
        crParameterValues = crParameterFieldDefinition.CurrentValues

        crParameterValues.Clear()
        crParameterValues.Add(crParameterDiscreteValue)
        crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)

        crParameterDiscreteValue.Value = BKCICTDatePicker2.Text
        crParameterFieldDefinitions = _
            repDoc.DataDefinition.ParameterFields
        crParameterFieldDefinition = _
            crParameterFieldDefinitions.Item("toDate")
        crParameterValues = crParameterFieldDefinition.CurrentValues

        crParameterValues.Add(crParameterDiscreteValue)
        crParameterFieldDefinition.ApplyCurrentValues(crParameterValues)
        CrystalReportViewer1.ReportSource = repDoc
        CrystalReportViewer1.Refresh()
    End Sub

    Private Sub VotReport_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

        Dim crSections As Sections
        Dim crSection As Section
        Dim crReportObjects As ReportObjects
        Dim crReportObject As ReportObject
        Dim myTable As CrystalDecisions.CrystalReports.Engine.Table
        Dim myLogin As CrystalDecisions.Shared.TableLogOnInfo
        Dim crSubreportObject As SubreportObject
        Dim crSubreportDocument As ReportDocument
        Dim crDatabase As Database
        Dim crTables As Tables
        Dim aTable As Table
        Dim crTableLogOnInfo As TableLogOnInfo
        Dim repDoc As New BkcictSpecCR 'Result is the report doc .rpt

        'For Each myTable In repDoc.Database.Tables
        myLogin = myTable.LogOnInfo
        myLogin.ConnectionInfo.ServerName = Application.StartupPath & "\UTMPOSS4.accdb"
        myLogin.ConnectionInfo.DatabaseName = Application.StartupPath & "\UTMPOSS4.accdb"
        myTable.ApplyLogOnInfo(myLogin)
        Next
        crSections = repDoc.ReportDefinition.Sections
        'loop through all the sections to find all the report objects
        For Each crSection In crSections
        crReportObjects = crSection.ReportObjects
        'loop through all the report objects in there to find all subreports 
        For Each crReportObject In crReportObjects
            If crReportObject.Kind = ReportObjectKind.SubreportObject Then
        crSubreportObject = CType(crReportObject, SubreportObject)
        'open the subreport object and logon as for the general report
        crSubreportDocument = crSubreportObject.OpenSubreport(crSubreportObject.SubreportName)
        crDatabase = crSubreportDocument.Database
        crTables = crDatabase.Tables
       
           End If
        Next
         Next
        CrystalReportViewer1.ReportSource = repDoc

    End Sub
End Class

I have a form of 2 datetimepicker and a button, a crystalreportviewer also.
