问题描述

USB扫描仪实际上并不需要代码.大多数USB扫描仪仅模拟键盘.因此,如果您有一个具有焦点的TextBox,则当扫描仪扫描条形码时,它将把扫描的数据放入条形码中,就像键入它一样.

是真的..

A USB scanner doesn''t really require anything from code. Most USB scanners simply emulate a keyboard. So if you have a TextBox that has focus, when the scanner scans a barcode, it will put the scanned data into the barcode just as if it was typed.

Is this true..

推荐答案

通常是的-但是通常可以对它们进行编程,以提供一个导入字符和尾部字符来将数据与其他字符分开.不过,这取决于制造商.
Generally, yes - but they can normally be programmed to provide a leadin and tailout character to separate the data from the other characters. That is manufacturer dependant, though.
