How can I pass a parameter to Crystal Report 5 from Visual Basic Screen?

I am using Crystal Report 5 with Visual Basic 6. I like a use select a data from Visual Basic Screen and list value in the VB report, based on the selection. How can I pass a parameter to Crystal Report 5 from Visual Basic Screen?

Report.RecordSelectionFormula =

Where can I put this code?
How can I specify the passed value parameter?

This is an example i use in one of my programs.
Most of the code has to do with calculating the formula
all you need is to put that Report.ReportSelectionFormula =
into the formload event on your form that displays the
report.

VB Code:

Dim Report As New CrystalReport1
 
Private Sub Form_Load()
 
Screen.MousePointer = vbHourglass
 
'***************** Get Date from List and Reorder for Year/Month/Day ************
Dim TheDate, strYear, strMonth, strDay, CrystalParameter As String
Dim Index As Integer
Dim numYear, numMonth, numDay
TheDate = ""
CrystalParameter = "{dtcelluse.dteDate} = date("
 
Index = 0
 
Do While Index < Reports.List1.ListCount
    If Reports.List1.Selected(Index) Then
        numYear = Year(Reports.List1.List(Index))
        numMonth = Month(Reports.List1.List(Index))
        numDay = Day(Reports.List1.List(Index))
        If TheDate <> "" Then
            TheDate = TheDate & " OR " & CrystalParameter & numYear & "," & numMonth & "," & numDay & ")"
        Else
            TheDate = CrystalParameter & numYear & "," & numMonth & "," & numDay & ")"
        End If
    End If
    Index = Index + 1
Loop
 
'Here is the Important Stuff
Report.DiscardSavedData     'Gets rid of REFRESH problem
Report.RecordSelectionFormula = TheDate 'Gives Selection Parameter
 
CRViewer1.ReportSource = Report
CRViewer1.ViewReport
Screen.MousePointer = vbDefault
 
End Sub
