without saving the pdf file showing the print preview

hi ...

i've created one crystal report in windows form and one crystalreportviewer ..

the following is my code..

in form1.cs file

try
{
ExportOptions CrExportOptions;
DiskFileDestinationOptions CrDiskFileDestinationOptions = new DiskFileDestinationOptions();
PdfRtfWordFormatOptions CrFormatTypeOptions = new PdfRtfWordFormatOptions();
CrDiskFileDestinationOptions.DiskFileName = "c:\\csharp.net-informations.pdf";
CrExportOptions = cryRpt.ExportOptions;
{
CrExportOptions.ExportDestinationType = ExportDestinationType.DiskFile;
CrExportOptions.ExportFormatType = ExportFormatType.PortableDocFormat;
CrExportOptions.DestinationOptions = CrDiskFileDestinationOptions;
CrExportOptions.FormatOptions = CrFormatTypeOptions;
}
cryRpt.Export();
}
the above code is saving the file into pdf into specified path..

but i dont want to save a file i should get direct print preview and

have a option to print ..



As we do in web application using crystal report viewer clicking print

and report will be opened in pdf.. and the click print..



i want the same function as we do in web application...

i'm writing code in c#.net if the code is vb also its ok

hope the above explaination will be understood clearly..
