Question

I have a CSV file which has a column for time and the time is formatted to look like (in the CSV file)
08:22:07

DataGridView will convert it to look like

12/30/1899 8:22 AM

Any suggestions?

My code looks like

    public static DataTable ParseCSV(string path, String pattern)
    {
        if (!File.Exists(path))
            return null;
        string full = Path.GetFullPath(path);
        string file = Path.GetFileName(full);
        string dir = Path.GetDirectoryName(full);
        string connString = "Provider=Microsoft.Jet.OLEDB.4.0;"
            + "Data Source=\"" + dir + "\\\";"
            + "Extended Properties=\"text;HDR=Yes;FMT=Delimited\"";
        string query = "SELECT [Pc-Tag], [User-Name], [Date], [Time] FROM " + file;// +" WHERE [User-Name] LIKE " + pattern;
        DataTable dTable = new DataTable();
        OleDbDataAdapter dAdapter = new OleDbDataAdapter(query, connString);
        try
        {
            dAdapter.Fill(dTable);
        }
        catch (InvalidOperationException ioe)
        {
            Console.WriteLine(ioe.Message.ToString());
        }
        dAdapter.Dispose();
        return dTable;
    }

You could configure the column to use a certain format string like T, which is the long time format (hh:mm:ss).

Use the DefaultCellStyle.Format property of the column containing your time value to do that. You can either use the Forms designer (click the little arrow that’s displayed when you select the DataGridView control and then choose “Edit columns”, select the column and then press the “…” button for the DefaultCellStyle property) or you can do it in code.

Just make sure to add the columns manually (either in the designer or in code) and set the AutoGenerateColumns property to false.
