Problem Printing Crystal Reports

Hi

I am using VS2010 on Windows 7, 64 bit and crystal reports for vs2010.

CrystalReportViewer CRV = new CrystalDecisions.Web.CrystalReportViewer();

CRV.ReportSource = AnalysisReports;

CRV.PrintMode = CrystalDecisions.Web.PrintMode.ActiveX;

The above code is to select printer on client machine by displaying print dialog window, but the print dialog window is not displayed.

Any help is highly appreciated.

Thanks n Regards
