条码实施... [英] barcode implementation...

问题描述

嗨......
我需要在dotnet(vb或c#)中为商店开发应用程序，因为我必须借助条形码读取器来销售商品，并且必须为每个商品生成标签..我获得了一些用于条形码标签的资源一代.整个过程还不太清楚，所以任何人都可以帮助我使用条形码读取器创建标签和出售物品.

此站点上有一个用于生成条形码的库.如果您有一个商业项目，那么您都需要开放购买图书馆(如果您的工资是合理的，则b/c，图书馆的费用应少于您编写图书馆的费用) )，并能够为自己做一些基本的搜索.如果没有文章，那么当您获得付款时，没有人会免费为您编写代码.就目前而言，它确实存在，您只需要搜索该站点，便会找到它.

您好，

您需要一个数据库，其中包含每个产品的唯一标识号(以及价格等其他数据).然后，您需要一个为这些产品创建标签的应用程序.然后必须将条形码读取器连接到该数据库，然后可以确定哪些产品与扫描的条形码相对应.

哦，男孩！蠕虫病毒即将到来.我认为您的产品尚未附带条形码-大多数都带有条形码，但是如果您要打印自己的条形码，则需要小心.您不能只是随意使用条形码，它们会编码一个称为商品编号的编号，该编号对于特定的产品包装必须是唯一的. (即，一包200克的MyCompany消化饼干与300克的MyCompany消化饼干需要不同的代码，而且这两种代码都不能用于世界上任何其他产品.)

如果您使用的是正在使用的代码，则您的产品可能会误读为现有产品，或者现有的产品可能会误读为您的产品之一-因为商品编号是就计算机系统而言的产品，因此会为误读定价.

为此，几乎所有国家/地区都有一个国家/地区组织，该组织(收费)发布每个商品编号.

另一种解决方案是使用(更复杂的)条形码，例如EAN128，该条形码允许使用字段(例如序列号).然后，您可以将序列号绑定到产品上并据此进行定价.

另请注意，在大多数国家/地区，通过条形码对价格进行法律限制，其中规定了可能进行价格更改的顺序，如果您不遵循价格，将处以(大笔)罚款！

There''s a library on this site for generating bar codes. If you''ve got a commercial project, you need to both be open to buying a library ( b/c if you''re being paid a fair wage, the cost of a library should be less than the cost of you writing it ) and be able to do some basic searching for yourself. If no article exists, no-one is going to write the code for you, for free, when you''re being paid. As it stands, it does exist, you just need to do a search of the site and you''ll find it.

Hi,

you need a data base that holds a unique identification number for each product (and other data like prices). Then you need an application that creates the labels for these products. The barcode readers must then be connected to this database and can then determine which product corrsponds to the scanned barcode.

Oh boy! Can-of-worms coming up. I assume that your products do not already come with barcodes - most do, but if you are printing your own, then you need to be careful. You cannot just use a barcode at random, they encode a number called an Article Number which must be unique to a specific packet of product. (i.e. a packet of 200g of MyCompany Digestive Biscuits needs a different code from a 300g packet of MyCompany Digestive Biscuits, and neither code can be used for any other product in the world.)

If you use a code which is in use then either your product could be misread for an existing product, or an existing product may be misread as one of yours - since the Article number is the product as far as the computer system is concerned, it will price it for the misread.

To this end, there is a national organisation in nearly all countries which issues (for a fee) each Article Number.

The other solution is to use a (more complex) barcode such as EAN128, which allows fields to be used such as a serial number. You could then tie the serial number to a product and price it accordingly.

Also be aware that there are (in most countries) legal restrictions on pricing via barcodes, which set out the order in which price changes may be made, and the (large) fines that are applied if you fail to follow them!
