refresh a crystal report

[engnouna]

Hi
I am using VB6,crystal report 9 and SQL server 2000,I have a command button that displays the report inside crystal report viewer,but every time i need to display a report,the crystal viewer displays to me the last report so i need to press on refresh to view the current report.
I tried in my VB6 code the following code to make the refresh automatic but it didn't work

Rs.Open str2, cnn, adOpenStatic, adLockOptimistic
Set oApp = New CRAXDRT.Application
    Set oReport = oApp.OpenReport(App.Path & "\Report2.rpt", 1)
    oReport.Database.SetDataSource Rs, 3, 1
    crvMyCRViewer.ReportSource = oReport
    crvMyCRViewer.ViewReport
    crvMyCRViewer.Refresh
Rs.Close

where should I place crvMyCRViewer.Refresh?

thanks

in crystal make sure you aren't saving the data with the report... in CR 11 it is under the File menu.

CRViewer1.EnableRefreshButton = True

Rs.Open str2, cnn, adOpenStatic, adLockOptimistic
Set oApp = New CRAXDRT.Application
    Set oReport = oApp.OpenReport(App.Path & "\Report2.rpt", 1)
    oReport.Database.SetDataSource Rs, 3, 1
   CRViewer1.EnableRefreshButton = True
    crvMyCRViewer.ReportSource = oReport
    crvMyCRViewer.ViewReport
    crvMyCRViewer.Refresh
Rs.Close

now refresh the report
