When I display my CSV file into my DataGridView some of the cells in the first row are blank.

I am displaying the contents of a CSV file into a DataGridView using an OleDbAdapter. The problem is once the data is in the DataGridView, some of the cells in the first row(which is the column headers in the CSV file) are blank. I have noticed the cells that are blank, are the header text for a column that contain numbers. I have tried placing quotes around the numbers in the CSV file and around the column headers but that has not helped. I am using cs.net 2008. In the code, fileName is a variable that is set before the TryCatch. All the data with the exception of row one is displaying correctly. Any help will be greatly appreciated.
OleDbConnection myConn = new OleDbConnection(connString);
            try
            {
                myConn.Open();
                DataTable dTable = new DataTable();
                OleDbDataAdapter myDa = new OleDbDataAdapter("SELECT * FROM[" + fileName + "]", myConn);
                myDa.Fill(dTable);
                myConn.Close();
                this.dataGridView_MonitorResults.DataSource = dTable;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.ToString());
            }

can you give us the header row from the csv?   Try putting [] around the header.

Yes here is the information from the header row.
store_nbr, country_code,thin_client_name,firmware_version_code,hardware_type_code,os_version_code,mac_address_id,ip_address_id, serial_nbr, online_ind, last_reimage_ts, last_change_ts, up_time_duration_ts, purchase_date, manufacture_date, end_of_life_date, screen_resolution_txt, refresh_rate_htz_qty, touch_scrn_calib_txt, ntwk_speed_mb_qty, disk_space_byte_qty, memory_byte_qty,

I will try the [] and will let you know.

I tried putting in the [] and that did not help.

Hi rsgage;

Can you post a sample file that causes the problem. I have used this before without that type of a issue.

Here is a sample. Normally it is named .csv but I coud not upload that type of file. The contents are the same though.

Hi rsgage;

I used your code and your test file that you posted and all column headers were displayed in the DataGridView. The only thing I can think of is that we are using different connection strings, this is the one I used:

string connString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\Temp\;Extended Properties=""text;HDR=Yes;FMT=Delimited""";

Note that in the connection string d:\Temp\ is the directory that the CSV file is located in.
