Migrating a legacy .rpt file to use ado.net dataset

Hello again,

I am evaluating migration of old (CR 6) reports to VB.net VS2008 (and then to VS2013). Using the CR tools in VS2008. I am having a problem linking the ADO.Net DataSet Object with the legacy report. I think this is due to a naming mismatch from the table/field references in the original legacy .rpt file and the new DataSet table names, etc. Here is what I have attempted ( some code omitted).

Dim odbcCmd As New OdbcCommand

Dim cryRpt As New ReportDocument

odbcCmd.CommandText = "SELECT el.PostDate, el.Severity, el.Message, el.Application, el.ErrorNumber, el.UserName, el.WorkStation, el.Extra FROM el_dbo.eventlog el WHERE el.PostDate >= { ts '2014-12-01 00:00:00' } AND el.PostDate <= { ts '2014-12-08 15:30:00' } "

Dim myAdapter As New OdbcDataAdapter()

myAdapter.SelectCommand = odbcCmd

Dim myDataSet As New DataSet()

myAdapter.Fill(myDataSet, "el")

cryRpt.Load("mtReport.rpt")

cryRpt.SetDataSource(myDataSet)

SetDBLogonForReport(myConnectionInfo, cryRpt)

CrystalReportViewer1.ReportSource = cryRpt

CrystalReportViewer1.Refresh()

I named the Dataset Table as "el" to match the query results. When I look at the contents of the myDataSet, it looks like:

<NewDataSet>

<el>

<POSTDATE>2014-12-01T10:34:26-05:00</POSTDATE>

The report data fields look like this (from the legacy report file)

However, when I run the report, I get this error:

This leads me to believe that the report db fields cannot be found in the ado.net dataset because they are encased in the top-level element. Is this a correct assessment, and if so, how to rectify? Thanks.
