适用于Visual Basic的良好条形码扫描API [英] Good Barcode Scanning APIs for Visual Basic
问题描述
最受欢迎且支持良好的驱动程序库是什么？
包含Visual Basic和C / C ++ API的代码扫描程序？我的要求
是：
- 必须允许将应用程序写入单个界面，但支持
许多不同的制造商''条形码扫描设备。我不想将
绑定到一个制造商的软件界面。
- 必须支持使用Visual Basic中的扫描仪，最好是来自C / C ++
和Java。
- 必须为Visual Basic提供一个回调接口，这样一个应用程序
就可以了听取某个事件并采取适当的行动。我们希望
支持能够同时快速扫描物品的同时操作许多库存物品的能力。
- 更愿意处理得到良好支持的图书馆以及来自大公司的b $ b b。如果只有一个人的公司生产这些产品，我们会考虑它（因为我们别无选择）。
- 通常便宜比贵的更好。
我很感激有人提出建议并讨论它们并发布
链接到制造商的网站。

What are the most popular, and well supported, libraries of drivers for bar
code scanners that include a Visual Basic and C/C++ API? My requirements
are:
- Must allow an application to be written to a single interface, but support
many different manufacturers'' barcode scanning devices. I do not want to
be tied to one manufacturers'' software interfaces.
- Must support use of the scanner from Visual Basic, and ideally from C/C++
and Java as well.
- Must provide a callback interface for Visual Basic, so that an application
can listen on a certain event and take appropriate action. We want to
support the ability to have many inventory items operated on at once by
scanning items rapidly in succession.
- Would prefer to deal with libraries that are well supported and which come
from larger companies. If only one-person companies make these kinds of
products, we''ll consider it (because we have no choice ).
- Cheap is usually better than expensive.
I would appreciate anyone with recommendations discussing them and posting
links to the manufacturers'' web sites.

are:
环顾''键盘楔形''条形码扫描仪;
它们连接键盘和PC。
不需要特殊的API或库。
扫描码按正常击键发送到PC
$ b你可以在KeyPress（）事件中读取$ b。我使用的那个
在条形码字符串前加上一个Asc（144）字符
来表示条形码输入。
我认为生产了很多这种类型的扫描仪。
一些mfrs。创建带有可拆卸条形码的键盘
扫描仪，但这些都有点贵。
如果你真的想要，真的很便宜，看看eBay是否还有
任何''Cue Cat''扫描仪出售！ :)
希望这会有所帮助。
Look around for ''keyboard wedge'' barcode scanners;
they connect between the keyboard and the PC.
No special API or libraries needed.
Scanned codes are sent to the PC as normal keystrokes
you can read in a KeyPress() event. The one I use
prefaces the barcode string with an Asc(144) character
to denote barcode input.
I think quite a few scanners of this type are produced.
Some mfrs. create keyboards with detachable barcode
scanners, but these are a bit pricey.
If you want really, REALLY cheap, see if eBay still has
any ''Cue Cat'' scanners for sale! :)
Hope this helps.
键盘楔不符合我们的应用要求。让我
给出一个典型的用例：
- 库存管理员需要给承包商60件物品进行测试。
- 库存管理器打开一个应用程序来指定承包商保管
卡。
- 库存管理器快速刷60张卡然后在视觉上/>
确认所有卡都已输入，点击确定。
使用键盘楔形，库存管理器必须：
1 ）为下一个项目选择编辑文本
2）扫描并确认单个项目的输入
然后重复上述60次。这非常麻烦。
P.S.我们尝试过Cue-Cat。 :)它不适用于我们特定产品的酒吧
代码。

Keyboard wedge doesn''t meet the requirements of our application. Let me
give a typical use case:
- Inventory Manager needs to give a contractor 60 items for testing.
- Inventory Manager opens up an application to assign contractor custody of
cards.
- Inventory Manager quickly swipes 60 cards and then after visually
confirming that all cards are entered, hits OK.
Using keyboard wedge, the Inventory Manager must:
1) Select an Edit Text for the next item
2) Scan and confirm entry for individual item
Then repeat the above 60 times. It''s very cumbersome.
P.S. We tried Cue-Cat. :) It doesn''t work on our particular products'' bar
codes.

什么？
这听起来像是胡说八道
为什么还要使用文本框？
- 最简单的方法是将Form.KeyPreview设置为true并简单地将
读入字符串
就个人而言，我会使用一个更优雅的解决方案，使用
UserControl构建 - 但使用相同的原理
What ?
That sounds a load of nonsense
Why use a Textbox anyway ?
- the simplest method is to set the Form.KeyPreview to true and simply
read in the strings
Personally I would use a more elegant solution built from a
UserControl - but using the same principle
