C#不用HID采用键盘钩子区分键盘输入和扫描枪数据的方法
扫描枪模拟键盘模式输入数据,从而无法区分键盘人工输入数据和扫描枪的数据,造成数据混乱。
使用HID接口模式调用WindowsAPI读取的方式由于受到不同操作系统有不同情况的问题,难以解决问题。
因此采用键盘钩子区分键盘输入和扫描枪数据。
键盘人工输入时间不均匀,而扫描枪一次数据间隔均匀,因此采用键盘钩子获得所有的键盘消息,如果连续多个键按键间隔小于30ms,且最后一个键以后连续500ms没有输入,就表明此串信息为扫描枪数据。

    很好,注释很详细。对于一维条码很管用。二维条码由于有不可打印字符,因此,不一定很贴合需要。2018-03-08
