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
        cn.Close()
 
        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")
                Else
                    str = str & drRow(dcColumn.ColumnName) & Chr(9)
                End If
            Next
            sw.WriteLine(str)
        Next

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.

I added the following line to my Schema.ini file and that took care of it...
