Reporting Services 2005 Report Parameters - Windows Application

SQL Server 2005/Reporting Services 2005

I have created a Windows Forms application and it includes several reports that I am rendering in reporting services utilizing the reportviewer control. My problems is that the parameter prompts are not displayed when the reports render. When I run the reports directly from reporting manager the parameter prompts are displayed.

I have set Me.ReportViewer1.ShowParameterPrompts = True. They still don't display.

Through my research all I've found is this:

Code:

---

Dim params(2) As Microsoft.Reporting.WinForms.ReportParameter
                params(0) = New Microsoft.Reporting.WinForms.ReportParameter("ReportMonth", 6)
                params(1) = New Microsoft.Reporting.WinForms.ReportParameter("ReportYear", 2007)
                params(2) = New Microsoft.Reporting.WinForms.ReportParameter("CustomerID", "125")
                ReportViewer1.LocalReport.SetParameters(params)

---

This makes no sense to me. Why would I need a parameter if I'm going to hard code the parameter values? I would have just hardcoded the values in the query itself.

First: How do I get the report parameter boxes to show?
Second: How can I pass in the parameters supplied by the user at run time?

Thanks in advance!
