在表单中使用条形码阅读器时出现问题 [英] Problem while using the bar code reader in a form

问题描述

我有一个手动工作的发票表格...我试图使用条形码阅读器它不能正常工作。

表单包含12行，每行与其他行相似一个。并包含这些未绑定的文本框和一个组合框。

首先我有一个名为type的组合框。 ，之后我有了article.txt，然后是size.txt，之后我得到了关于价格的所有描述...

typei，articlei，sizei，.... 1 <我< 12

当我打开表格时，光标在article1.txt上设置...当我使用条形码输入第一篇文章时...文章正确输入没有任何问题，光标现在在article2.txt。

所以现在我尝试通过条形码阅读器输入另一篇文章...当我使用dar代码...在这里我发现组合框type2。 txt已从其内容中删除，而默认情况下它必须保持等于R（默认情况下，typei.txt = R）。现在我要用条形码阅读器输入文章我应该重新输入type2的值（默认为R），之后按回车键设置焦点在article2.txt然后我再使用条形码阅读器时间和现在它起作用了...但是请知道为什么会发生这种情况吗？希望我向大家说清楚！请回复...非常感谢你们

I have a invoice form that works manually ... I tried to use the bar code reader it didn''t work well.
the form contains 12 lines each line is similar of the other one . and contains these unbound text boxes and one combo box.
first i have a combo box named "type" , after that i have the article.txt , and after that the size.txt , after that i got all the descriptions about the price ...
typei , articlei , sizei , .... 1 < i < 12
well when i open the form the cursor is set on the article1.txt ... when i use the bar code to enter the first article ... the article enter correctly without any problem and the cursor is now on article2.txt.
So now i try to enter another article by the bar code reader ... when i use the dar code... here i discover that the combo box type2.txt has erase from his content , while it must stay equal to R by default (typei.txt = R by default). and to enter the article with the bar code reader now i should reenter the value of type2 (that is R by default) and after that press enter to go to set the focus on article2.txt and then i use the bar code reader a second time and now it worked ... but please does any one know why is that happening ? hope that i made it clear to all ! please reply ... many thanks to you guys

推荐答案

呃......清楚如泥。这是一个关于名称的链接，你不应该*用于数据库中的对象： http://www.allenbrowne.com/AppIssueBadWord.html 您已经使用了一些。对于我们虚弱的读者，您可能希望以稍微不同的术语来描述问题。 ;）

Uhh...clear as mud. Here''s a link about name that you should *not* use for objects in your db: http://www.allenbrowne.com/AppIssueBadWord.html You have used some. You may want to describe the issue in slightly different terms for us feeble minded readers. ;)

实际上，字段名称是FromFromR_S;而不是键入

而我没有得到它!!

这些是我的字段名称：

achat_num， article，size，fact_num，quantite_vendu，prix_vente_unitaire，difference，fromR_S。

Actually the field name is From "FromR_S" and not "Type"
and i didn''t get it !!
these are the names of my fields :
achat_num , article , size , fact_num , quantite_vendu , prix_vente_unitaire , difference , fromR_S.

条形码阅读器一直用于Access应用程序。在提到ComboBox时，我真的不明白你在谈论什么。调用控件 article.txt 也会让我感到困惑。什么是.txt？

Bar code readers are used on Access applications all of the time. I do not really understand what you are talking about when referring to the ComboBox. Calling a control article.txt confuses me as well. What is the .txt for?
