问题描述

我在做一个应用程序在一个salespoint后台运行从USB扫描仪读取输入。
我怎样才能从C#扫描仪的输入?
而且我可以扫描仪和USB键盘区分? (Scanner是一款HID设备)

I'm making an application to run in the background on a salespoint to read input from a usb scanner.How can I get the input of the scanner from C#?And can I differentiate between the scanner and a usb keyboard? (Scanner is a HID device)

推荐答案

我这样做是成功地运用在$ C $的CProject一个原始输入实施前:

I did this successfully before using a "Raw Input" implementation on CodeProject:



  • Raw Input

它可以让你同时接收输入(什么是钥匙是$ P $,如果它模仿键盘pssed),以及区分它来自哪个设备。

It allows you to receive both the input (what "keys" are pressed if it mimics a "keyboard") as well distinguish which device it came from.
