C＃和扫描仪probs ... [英] C# and scanner probs...
问题描述
嘿伙计们，
我想知道你是否可以请我提供一些关于如何获得
来解决这个问题的想法。
[场景]
符号MC9000-k，Pocket PC 2003 ...我用扫描仪应用程序写了，
数据是当用户执行某些操作时加载到ArrayList结构中。
此列表包含当前接受的条形码编号列表。
最后，我手中有一个手动输入按钮用户可以申请
的应用程序（如果条形码被损坏），手动输入条形码编号。
然后将输入的数据传递到相同的函数中在扫描后被称为
。
[问题]
有时扫描仪会进入一种返回错误的模式说
当我们知道扫描的任何条形码都没有在数据列表中找到
是。通过手动输入条形码编号证明这一点，
正确地按照您的预期记录条形码。
如果应用程序重新启动，突然扫描适用于所有条形码
您期望的数据。
正如我所提到的，手动输入和扫描，调用相同的程序...
当出现扫描仪错误消息时，扫描的条形码显示为
，这看起来是正确的！？！？
这完全是我的头脑和任何帮助真的很好
赞赏。
谢谢。
Dan。
Hey guys,
I wonder if you could please provide me with some ideas as to how to get
around this problem.
[Scenario]
Symbol MC9000-k, Pocket PC 2003... With a scanner application I''ve written,
data is loaded into ArrayList structures when the user performs some action.
This list contains a list of barcode numbers that are currently accepted.
Finally, there is a manual entry button in my application where the user can
(if the barcode is damaged for example), manually put in the barcode number.
This then passes the entered in data into the same function that is called
after a scan.
[Problem]
Some times the scanner gets into a mode where it returns an error saying
that any barcode scanned is not found in the list of data when we know it
is. This is proved by manually entering in the barcode number which
correctly registers the barcode as you''d expect.
If the application is restarted, suddenly scanning works with all barcode
data you''d expect.
As I mentioned, the manual entry, and scanning, call the same procedure...
When the scanner error message appears, the barcode that was scanned is
displayed and this appears correct!?!?
This is thoroughly doing my head in and any help would really be
appreciated.
Thanks.
Dan.

此列表包含条形码编号列表目前已被接受。
最后，我的应用程序中有一个手动输入按钮，用户可以（例如，如果条形码损坏），手动输入条形码编号。

扫描仪返回数据的格式是什么？你能有一些
的尾随空格，或类似的东西吗？

What format does the scanner return the data is? Could you have some
trailing spaces, or something like that?

Jon，
当符号库通过数据时，它只是在一个字符串中，并且
我之前确认它的字符串与你期望的相同。没有
空格预先/附加条形码...
如何在一分钟内无法正常工作，然后在应用后工作正常
重启？！？！ ** 8-&
符号开发支持很好，不存在。

Jon,
By the time the symbol library passes by the data it''s just in a string, and
I confirmed it earlier that the string is identical to what you''d expect. No
spaces pre/appending the barcode...
How can it not work one minute, then work fine the next after a app
restart?!?! **8-&
And symbol dev support is well, non-existent.

你是如何确认的？可能还有空格以外的东西 - 例如，
字符。
我不相信方法会知道字符串的来源，所以如果
相同字符串在手动输入模式下工作，我不相信它实际上是相同的字符串。
一分钟怎么能不工作，然后工作正常在应用程序重启后接下来？！？！ ** 8-&

spaces pre/appending the barcode...
How did you confirm that? There may be things other than spaces - nul
characters, for example.
I don''t believe a method will know where a string comes from, so if
"the same" string works in manual entry mode, I don''t believe it''s
actually the same string.
How can it not work one minute, then work fine the next after a app

嗯，这是另一回事 - 如果扫描仪*已*开始
包括一些虚假数据，然后重置东西很可能会产生一个
的差异。

Well, that''s a different matter - if the scanner *has* started
including some bogus data, then resetting things could well make a
difference.
