Crystal Report prompt still showing, even though I pass param value to report

[Michael]

I followed the solution document at the
http://support.businessobjects.com/l..._netzone_howto
.. However, the Crystal Report prompt is still showing. The following
are my scenario, the platform, and partial code information.

Thanks in advance for the help,

------------------------
1. Scenario: I am trying to pass the parameter value to an embedded
Crystal Report file from C#.NET application. The report binds to a SQL
Stored Procedure. The stored procedure expects a parameter value
passed in by the application.

2. The application is C# WinForm, VS.NET 2003, Crystal Report v10
Developer, Windows 2000 and XP.

3. Here are partial code:
CustomerBasic custBasic = new CustomerBasic() ;
ParameterValues pvCustPattern = new ParameterValues ();
ParameterDiscre teValue pdvCustPattern = new ParameterDiscre teValue();
pdvCustPattern. Value = "A";
pvCustPattern.A dd(pdvCustPatte rn);
cbsMain.DataDef inition.Paramet erFields["@CustPatte rn"].ApplyCurrentVa lues(pvCustPatt ern);

cvwMain.ReportS ource = custBasic;
