a barcode that the number will automaticly be entered into a .txt
file. I tired to use the most of the events and none have seemed to
work .Does anyone have any ideas. I and using VB.net 2005. Thank you
推荐答案
我的条码扫描器（Intermec）在文本的末尾添加了一个CRLF
自动，你的可能会这样做。如果你在KeyDown事件中查找
字符，你应该能够获取文本
并使用System.IO命名空间类来编写文件。 br />

character on the KeyDown event, you should be able to pick up the text
and use the System.IO namespace classes to write the file.

史蒂夫，
谢谢你的想法。我将不得不尝试一下，看看

Steve,

此外，
看一看com端口serialport对象也是如此。
一些新扫描仪是USB，它们有一个驱动程序实际上将一个
com端口分配给扫描仪的USB端口。
所以我所做的就是我让SerialPort听一个comport并刷新
到了topmost应用程序或我需要的任何文本框。

Also,
Take a look at the com port "serialport" object as well.
Some new scanners are USB and they have a driver that actually assigns a
com port to the USB port of a scanner.
So what I do is I have teh SerialPort listening to a comport and flush
that to the "topmost" application or to whatever textbox I need to.
