            string connectionstring = null;
            string sql = null;
            string data = null;
            int i = 0;
            int j = 0;
            string title=store.Text;
 
            Excel.Application xlApp;
            Excel.Workbook xlWorkBook;
            Excel.Worksheet xlWorkSheet;
            object misValue = System.Reflection.Missing.Value;
 
 
            xlApp = new Microsoft.Office.Interop.Excel.Application();
            xlWorkBook = xlApp.Workbooks.Add(misValue);
            xlWorkSheet = (Excel.Worksheet)xlWorkBook.Worksheets.get_Item(1);

            connectionstring = "Data Source=user-pc\\sqlexpress;Initial Catalog=StoreBarcode;Integrated Security=True";
            cnn = new SqlConnection(connectionstring);

            try
            {
                cnn.Open();
                sql = "SELECT * FROM Barcode." + title + "";
                SqlDataAdapter dscmd = new SqlDataAdapter(sql, cnn);
                DataSet ds = new DataSet();
                dscmd.Fill(ds);

                for (i = 0; i <= ds.Tables[0].Rows.Count - 1; i++)
                {
                    for (j = 0; j <= ds.Tables[0].Columns.Count - 1; j++)
                    {
                        data = ds.Tables[0].Rows[i].ItemArray[j].ToString();
                        xlWorkSheet.Cells[i + 1, j + 1] = data;
                    }
                }
            }
            catch
            {
                MessageBox.Show("Choose from Store to Export!");
            }

            try
            {
                xlWorkBook.SaveAs(""+title+".xls", Excel.XlFileFormat.xlWorkbookNormal, misValue, misValue, misValue, misValue, Excel.XlSaveAsAccessMode.xlExclusive, misValue, misValue, misValue, misValue, misValue);
                xlWorkBook.Close(true, misValue, misValue);

                xlApp.Quit();


                releaseObject(xlWorkSheet);
                releaseObject(xlWorkBook);
                releaseObject(xlApp);

                MessageBox.Show("Excel file created , you can find the file @ C:\\Users\\User\\Documents");
            }
            catch {
                MessageBox.Show("Exporting has been Cancelled!");
