vb6中的条形码扫描仪 [英] barcode scanner in vb6

问题描述

你好



我已经发了一张发票表格，我想在扫描物品的条形码后在账单表中添加产品。我在bytescout条形码sdk的帮助下创建并打印了条形码，我将这些打印的条形码存储在mysql后端的产品表中。

我只想用我的lappy的网络摄像头扫描条形码或通过Android应用程序，所以请告诉我如何将其与我的vb表单连接？

我不想购买任何条形码扫描仪，因为它只是我的学校项目。



谢谢。

解决方案

市场上有自动启动QRCode /条码扫描器，买一个并安装。在VB窗体启动时，sutfocus在搜索字段上，应该期望条形码（由设备解码）查询您的数据库。使用扫描仪将打印的条形码扫描到文本框中。你的问题应该解决。



您正在使用网络摄像头进行挑战，这也是可能的，但比使用条形码扫描仪更复杂。



如果您想进一步使用网络摄像头，请下载VBQRCode库并对其进行更多研究。它在.Net上效果更好



我希望你能成功。



祝你好运！

hello

I have made an invoice form and i want to add products in bill table after scanning barcode of items. i have created and printed barcodes with the help of bytescout barcode sdk and i have stored those printed barcodes in the product table in backend in mysql.
I just want to scan the barcode with my lappy's webcam or through android app, so please tell me how to connect it with my vb form??
I don't want to purchase any barcode scanner as it is just my school project.

Thank you.

解决方案

There are Auto-start QRCode/Barcode scanners in the market, buy one and install. On your VB Form startup, sutfocus on the search field, which should be expecting the barcode (decoded by the device) to query your DB. Use the scanner to scan your printed barcode into the textbox. Your problem should be solve.

You're having challenge because you are using Webcam, which also is possible but more complex than using a barcode scanner.

If you want to further on the use of webcam, download the VBQRCode Library and do a little more research on it. It works better on .Net

I hope that you will succeed.

Good luck!
