阅读条形码 [英] Read Barcode

问题描述

I Guys：

我正在处理一个应用程序，以便从扫描仪中读取条形码，并且

将它们列在网页上的ListBox中。我想知道是否有人做了类似的工作。


目前我已经将扫描仪连接到我的电脑上并扫描了条形码

它读取并将其放在记事本或文本框上。

但我需要控制条形码并将其放入列表框中。


任何想法或代码都会非常感激。


谢谢

I Guys :
I am working on a Application to read barcodes from a scanner and
list them in a ListBox on a web page. I was wondering if any one has
done a similar job.

Currently I have attached the scanner to my PC and as I scan a barcode
it reads and puts it on a notepad or textbox.
But I need to have control over the barcode and put it in the listbox.

Any ideas or code will be really appreciated.

Thanks

推荐答案

条形码设备是否发送任何特殊字符首先？我不记得

了我的头脑，但我可以用信用卡扫描仪发誓

（类型设备） - 它发送像\\首先是\\ 0x10和其他东西，然后发送

它的字符串..


如果是这样，你可以捕获一个表单上的事件，当你看到

时，这些代码会出现 - 将焦点设置到文本框中。 ？


除此之外，如果它只是原始字符 - 我可能强迫用户一点点b / b $ b - 强迫窗口在顶部并强迫文本框重点关注，直到它们完成为止。添加商品???

Does the barcode device send any special characters first? I don''t remember
off the top of my head, but I could''ve sworn with a credit card scanner
(type device) - it sends like \0x10 and something else first, and then sends
it''s character string..

If that''s the case, you could capture an event on the form, and when you see
those codes come across - set focus to your text box. ?

Aside from that, if it''s just raw characters - I might force the user a
little bit - by say forcing the window on top and forcing the textbox to be
focused until they are "Done" adding items???

嗨大家好：

我正在处理一个应用程序来读取扫描仪和列表中的条形码

他们在网页上的ListBox中。我想知道是否有人做了类似的工作。这可能吗？


目前我已将扫描仪连接到我的电脑上，当我扫描条形码时，它会读取并将其放在记事本或文本框上。

但是我需要控制条形码并把它放在列表框中。

换句话说我想在进入
$之前进行一些验证b $ b列表框。

其次，在什么情况下我可以在

网页上捕获texbox中的值？

用户不能选项卡或单击页面。他只会继续扫描

条形码在页面上的另一个。窥视窥视。


任何想法或代码都会非常感激。


谢谢

Hi Guys :
I am working on a Application to read barcodes from a scanner and list
them in a ListBox on a web page. I was wondering if any one has done a
similar job. Is this possible ?

Currently I have attached the scanner to my PC and as I scan a barcode
it reads and puts it on a notepad or textbox.
But I need to have control over the barcode and put it in the listbox.
In other words I want to perform some validation before putting into the
list box.
Secondly under what event can I capture the value in the texbox on the
webpage ?
The user must not tab or click on the page. He wil just keep scanning
barcodes on after the other on the page. Peep Peep Peep.

Any ideas or code will be really appreciated.

条形码阅读器是否使用键盘楔或串行接口？如果使用键盘楔子是
，你需要强制将表格焦点转换为可编辑的

控件，例如TextBox，然后你可以使用TextChanged事件当扫描仪输入新的扫描代码时告诉

。如果它是一个串行接口，你可以只监视来自设备的数据包数据的串口。

有几个串口组件，免费和商业。我已经使用了几个免费的b $ b，但是我正在使用来自 www.componentscience.com 现在

从扫描仪上读取条形码。

Is the barcode reader using a keyboard wedge or serial interface? If it''s
using a keyboard wedge, you need to force the form focus to an editable
control, such as a TextBox, then you can use the TextChanged event to tell
when the scanner enters a new scanned code. If it''s a serial interface, you
can just monitor the serial port for the packet data coming from the device.
There are several serial components, free and commercial. I''ve used several
of the free ones, but I''m using TransPort from www.componentscience.com now
to read barcodes from a scanner.
