Crystal Report Viewer Date Issue

I use Crystal report Viewer to show my report using the following code

Code:

---

Dim CRReport As CrystalDecisions.CrystalReports.Engine.ReportDocument

        CRReport = New CrystalDecisions.CrystalReports.Engine.ReportDocument
        CRReport.Load(reportpath & "report1.rpt", [Shared].OpenReportMethod.OpenReportByDefault)
        CRReport.SetDatabaseLogon(dbuser, dbpass)
        CRReport.RecordSelectionFormula = "{rpt.EntNo}=5"
        CRReport.VerifyDatabase()
        CRReport.Refresh()

        Rpt.CrystalReportViewer1.ReportSource = CRReport
        Rpt.CrystalReportViewer1.ShowGroupTreeButton = False
        Rpt.CrystalReportViewer1.ShowGotoPageButton = True
        Rpt.CrystalReportViewer1.DisplayGroupTree = False
        Rpt.Show()

---

It Sounds good.

But the issues is Date field which shown in report is formated as dd-MM-yyyy in my crystal. But this not shown as if in report viewer it shows in mm/dd/yyyy.
