title: crystal report geeting blank while using stored procedure
body: <p>I have a stored procedure "ParkingSummary" that has three parameters. I try to pass a parameter to the crystal report but it doesn't show anything, it's getting blank.</p>
  
  <p>Below is my code:</p>
  
  <pre><code>Dim strConn As String = con.ConnectionString
  Dim rpt As New Test
  Dim sqla = New SqlDataAdapter
  Dim ds = New DataSet
  
  sqla.SelectCommand = New SqlCommand("ParkingSummary @locid, @startdate, @enddate", con.connect)
  sqla.SelectCommand.Parameters.AddWithValue("@locid", 5)
  sqla.SelectCommand.Parameters.AddWithValue("@startdate", "2013/1/1")
  sqla.SelectCommand.Parameters.AddWithValue("@enddate", "2013/1/1")
  sqla.Fill(ds, strConn)
  rpt.SetDataSource(ds.Tables(0))
  CrystalReportViewer1.ReportSource = rpt
  CrystalReportViewer1.Refresh()
  </code></pre>
  
  <p>what is wrong in this code?, please help me to find out.</p>
