推荐答案

我见过的条码扫描器我不得不承认）就像一个键盘一样。旧的甚至有一个PS / 2端口。但即使是USB的人也喜欢将自己标识为键盘。当你扫描一个代码时，扫描仪的行为就好像你实际上已经按下了键盘上的数字键，可能以一个返回键结束。

The barcode scanners that I have seen (not that many I have to admit) act like a keyboard. Old ones even have a PS/2 port. But even the USB ones like to just identify themselves as a keyboard. When you scan a code, the scanner behaves as if you would have actually pressed number keys on your keyboard, probably ending with a return key.

所以你要做的是把重点放在你的文本框中，扫描你的代码并完成。

So what you do is put a focus in your textbox, and scan your code and be done.
