 private System.Data.DataTable GetTable(string _SQL, string FileExcel)
        {
           string _ConnectionString = "Dsn=Excel Files;dbq=" + FileExcel + ";defaultdir=" + System.IO.Path.GetDirectoryName(FileExcel) + ";driverid=1046;maxbuffersize=2048;pagetimeout=5";
            System.Data.Odbc.OdbcConnection conn = new System.Data.Odbc.OdbcConnection(_ConnectionString);
            System.Data.DataSet ds = new System.Data.DataSet();
           
                conn.Open();
                string strQuery = _SQL;
                System.Data.Odbc.OdbcDataAdapter adapter = new System.Data.Odbc.OdbcDataAdapter(strQuery, conn);
                adapter.Fill(ds);

            /* try
            {}
            catch { }
            finally { }*/
            return ds.Tables[0];
