Hello,
Have a look at these parameter samples:

Don
Thanks for the response. I tried the link you provided but I was unable to open the zip file. I am using the ASP.NET ReportViewer and here is my code. I don't understand why I continue to be prompted for the parameters.
ReportDocument rdoc = new ReportDocument();
rdoc.Load(HttpContext.Current.Server.MapPath("~/system/reports/rpt-files/" + reportName + ".rpt"));
rdoc.SetDataSource(datasource);
rdoc.SetParameterValue("StartDate", DateTime.Parse("1/1/2011"));
rdoc.SetParameterValue("EndDate", DateTime.Parse("2/29/2012"));
CrystalReportViewer1.ReportSource = rdoc;
CrystalReportViewer1.ParameterFieldInfo = rdoc.ParameterFields;
CrystalReportViewer1.RefreshReport();
If I set the parameters before setting the data source, the parameters are cleared. I'm not sure if I'm supposed to be setting the ParameterFieldInfo on the ReportViewer or not; it doesn't seem to make a difference either way. I have confirmed that HasCurrentValue is true for both parameters before .RefreshReport()
Download the below zip file which contains the sample applications.
Take a look at sample "\ReportDocObjectModel\Parameters"
Thanks,
Bhushan.
I'm sorry but I still cannot open the zip you linked to. I tried to open it on two different computers using WinRAR and Windows compressed folders.
I wonder if KB [1214110 - How to pass a Date/Time parameter to a report at runtime using VB .NET|http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_bi/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes%7B6163636573733d36393736354636443646363436353344333933393338323636393736354637333631373036453646373436353733354636453735364436323635373233443330333033303331333233313334333133313330%7D.do] is the thing we're looking for?

The code in the linked example does not work either. Additionally, the example code is incomplete and, frankly, seems very inefficient. When do you load the report? Why is it necessary to set a variable for the current values from the parameter field definition object then pass it to ApplyCurrentValues after setting the value?
What exactly is the example code supposed to solve regarding datetime parameters? Is the issue that you need to set the time portion to 12:01:00 AM? If so, why is this even necessary?
Why doesn't the SetParameterValue method work for datetime parameters?
Take a look at the [Developer guide|http://help.sap.com/businessobject/product_guides/sapCRVS2010/en/crnet_dg_2010_en.zip] and [APi reference guide |http://help.sap.com/businessobject/product_guides/sapCRVS2010/en/crnet_api_2010_en.zip]for CRVS 2010 .NET SDk, which will answer all your questions.
