Barcode Scanning Needed for nopCommerce

Hi  

We use a barcode scanner to scan a barcode into a field on form - plug a scanner into the computer and it looks just like a keyboard puting the data in the current field. Then we use the value to read and display product data.

Here are the main bits of code from 1.7 PDFhelper to print a barcode on the PDF Invoice and as such can be used to print product or SKU barcodes for scanning back into your field on the form.

namespace NopSolutions.NopCommerce.BusinessLogic.Utils
{
    /// <summary>
    /// Represents a PDF helper
    /// </summary>
    public class PDFHelper
    {
        #region Methods

        static void AddTicketLogoHeader(Document document, Order order, Product Product, int languageId, string filePath)
        {

            Section section = document.LastSection;

            var table = section.AddTable();
            table.Borders.Visible = false;
            table.AddColumn(Unit.FromCentimeter(9));
            table.AddColumn(Unit.FromCentimeter(9));

            var ordRow = table.AddRow();

            if (File.Exists(LogoFilePath))
                ordRow[0].AddImage(LogoFilePath);

            string barCodeImgPath = filePath + ".jpg";
            GenerateBarCode(String.Format("{0:00}{1:00000}", Product.EventVenueId, order.OrderId), barCodeImgPath);
            ordRow[1].AddImage(barCodeImgPath);
            ordRow[1].AddParagraph();
            ordRow[1].AddParagraph();

            var sup = ordRow[1].AddParagraph("     " + SettingManager.StoreUrl.Trim(new[] { '/' }));
            sup.AddHyperlink(SettingManager.StoreUrl, HyperlinkType.Url);
            sup.Format.Font.Bold = true;
            ordRow[1].AddParagraph("     " + LocalizationManager.GetLocaleResourceString("PDFInvoice.ABN", languageId)).Format.Font.Bold = true;
            ordRow[1].AddParagraph("     " + String.Format(LocalizationManager.GetLocaleResourceString("PDFInvoice.OrderDate", languageId), DateTimeHelper.ConvertToUserTime(order.CreatedOn, DateTimeKind.Utc).ToString("D"))).Format.Font.Bold = true;
            ordRow[1].AddParagraph();
            ordRow[1].AddParagraph("     " + String.Format(LocalizationManager.GetLocaleResourceString("PDFTicketInvoice.Order#", languageId), order.OrderId)).Format.Font.Bold = true;
        }
