条形码阅读器的代码 [英] code for barcode reader

问题描述

你好......

我在asp.net做项目，我们正在使用条形码阅读器。现在我有两个文本框和一个图像框，分别用于产品代码，条形码和标签。在标签图像框中，我们显示产品上的条形码标签图像。现在我的问题是当我们从条形码阅读器中取出条形码时，条形码的值应该显示在我的第二个文本框上，条形码标签的自动图像也应该显示在我的图像框上。我不知道怎么能为这个任务编写代码。

hello ...

推荐答案

我也不是。



因为它取决于您的条形码阅读器。大多数都是在发货时配置模拟键盘，没有办法判断条形码数据何时开始以及何时完成 - 因此它出现在用户输入显示的位置。大多数可以配置为提供特定的引入和引出字符或字符串，但具体如何配置ius制造商（通常是模型）具体 - 所以首先与他们交谈，并找出如何。他们可能也有你可以下载的支持示例软件。

Nor do I.

Because it depends on your barcode reader. Most are configured when they are shipped to emulate a keyboard, sop there is not way to tell when barcode data starts and when it finishes - so it appears where the user input will appear. Most can be configured to provide specific "Lead in" and "Lead out" characters or strings, but exactly how they are configured ius manufacturer (and often model) specific - so start by talking to them, and find out how. They will probably have support example software you can download as well.
