Dataset does not return 1st row?

This might be easy but...
I've opened a CSV file using ADO, filled a DataSet from the result but I'm not getting the first row. Is this a 0 based thing?
cn = New ADODB.Connection

        cn.Open("Provider=Microsoft.Jet.OLEDB.4.0;" & _

                "Data Source=" & strInputFilePath & ";" & _

                "Extended Properties='text;HDR=NO;FMT=Delimited'")

        'create a new recordset

        rsSource = New ADODB.Recordset

        rsSource.CursorLocation = ADODB.CursorLocationEnum.adUseClient

        rsSource.CursorType = ADODB.CursorTypeEnum.adOpenStatic

        rsSource.LockType = ADODB.LockTypeEnum.adLockBatchOptimistic

        rsSource.Open("SELECT * FROM [" & System.IO.Path.GetFileName(strInputFile) & "]", cn)

        rsSource.ActiveConnection = Nothing


        Dim daDataAdapter As New System.Data.OleDb.OleDbDataAdapter()

        Dim dsDataSet As New DataSet()

        Dim drRow As DataRow

        daDataAdapter.Fill(dsDataSet, rsSource, System.IO.Path.GetFileName(strInputFile))


        Dim lngMaxRows As Long = dsDataSet.Tables(0).Rows.Count

        Dim sw As StreamWriter

        Dim dcColumn As DataColumn


        sw = New StreamWriter(strOutputFile)

        'Loop through Input file dataset

        For Each drRow In dsDataSet.Tables(0).Rows

            For Each dcColumn In dsDataSet.Tables(0).Columns

                If dcColumn.ColumnName.ToString = "SEQ_NO" Then

                    'format this field

                    str = str & drRow("SEQ_NO").ToString("00000000")


                    str = str & drRow(dcColumn.ColumnName) & Chr(9)

                End If

Do you mean your query itself is not returning the first row?
Is the dsDataSet.Tables(0).Rows.Count returning right count?

I don't know if it's not returning all or if the dataset isn't filled properly.  dsDataSet.Tables(0).Rows.Count returns 999 instead of the 1,000 records in the original CSV file.  The output file is missing the first record so it seems the 999 count is correct.
