Visual Studio 2005, embedded Crystal Report problem

Question

I am very new at .NET, and this is my first post to this forum.
I've created a Crystal Report within a project using Visual Studio 2005 Professional Edition, on a Windows XP machine.  I set the report as the ReportSource for a CrystalReportViewer on the main form.  I can see data in the report in design view when I right-click on any of the fields and click "Browse Field Data".  But when I preview the report, or run it in the application, all I see are the column headings and report title.  I am hoping I am leaving out something obvious.  I've researched this for two days without success. 
The report's detail section is NOT suppressed, btw.
FYI (although I think it might not be relevant, because I don't see the data when I preview it in Visual Studio either) the report is displayed in the application when a button is clicked, as follows:
    Private Sub cmdRunLog_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdRunLog.Click
            CrystalReportViewer1.DisplayToolbar = True
            cmdRunLog.Text = "Hide Run Log"
            cmdUpload.Enabled = False
            cmdReports.Enabled = False
            cmdManualRun.Enabled = False
            CrystalReportViewer1.Visible = True
            CrystalReportViewer1.Height = 600
            CrystalReportViewer1.Width = 1000
            CrystalReportViewer1.Left = 10
            Dim strReportSQL As String = "Select * From dbo.PositivePayRunLog"
            Dim DA As New SqlDataAdapter(strReportSQL, conPP)
            Dim DS As New DataSet
            'Variable to assign the report name
            Dim strReportPath As String
            DA.Fill(DS)
            strReportPath = "c:\Positive Pay\PositivePayRunLog.rpt"
            If Not IO.File.Exists(strReportPath) Then
                _ErrorText = "Unable to locate report file:  " & strReportPath
                ' Throw (New Exception("Unable to locate report file:" & vbCrLf & strReportPath))
                GoTo cmdRunLog_Click_Error
            End If
            Dim rptDocument As New CrystalDecisions.CrystalReports.Engine.ReportDocument
            rptDocument.Load(strReportPath)
            rptDocument.SetDataSource(DS.Tables(0))
            rptDocument.Refresh()
            CrystalReportViewer1.ShowRefreshButton = False
            CrystalReportViewer1.ShowCloseButton = False
            CrystalReportViewer1.ShowGroupTreeButton = False
            CrystalReportViewer1.ReportSource = rptDocument
end sub
I'm hoping that this is a common problem with an easy answer
Thanks,

I have done both, but I was currently using OLEDB.
I redesigned the report to use a dataset containing the correct data.  Now,  when I browse the fields, I see nothing.  When I preview the report, I see what appears to be dummy data (a list of colors, etc).
But the GOOD news is:  When I run the report in the application, I see the correct data!
Thanks!  I think I'm good to go now.  I will also apply the other suggestions, and try to simplify things.
