Crystal Reports DataTable from input file and report

Message

   I have tried for about 3 hours this week to get a DataTable (from an input file) to work with Crystal Reports.  The code below are some of the things that I have tried.  

'' *** Add existing DataTable to new DS. 
      Dim KeyWPrintTable As New DataTable
      Dim dsSelected1 As DataSet = New DataSet("KeyWPrintTable")

      Try

         '' *** Copy KeyWSelectedTable into the new DataTable.
         Dim myRows1 = From s In KeyWSelectedTable.AsEnumerable _
                      Where s.Field(Of Integer)(4) > 1 Or _
                      s.Field(Of Integer)(5) > 1 Select s

         KeyWPrintTable = myRows1.CopyToDataTable
         '' myReport1.SetDataSource(dsSelected1)
         '' CrystalReportViewer1.ReportSource = myReport1

         '' *** Try to get data from grid into report.
         DS_fromGrid1 = CType(DataGridViewSelected.DataSource, DataSet)
         myReport1.SetDataSource(DS_fromGrid1)
         CrystalReportViewer1.ReportSource = myReport1
         '' CrystalReportViewer1

The DataTable was created from the input file so I cannot drag anything over into the report.   I created the .rpt file and based it 
on the schema file DataSet2.xsd.  What do I now need to do to get this report to fill with data and print?   myReport1.SetDataSource(DS_fromGrid1) gave an error.
