資源簡介

掃描槍模擬鍵盤模式輸入數(shù)據(jù)，從而無法區(qū)分鍵盤人工輸入數(shù)據(jù)和掃描槍的數(shù)據(jù)，造成數(shù)據(jù)混亂。使用HID接口模式調(diào)用WindowsAPI讀取的方式由于受到不同操作系統(tǒng)有不同情況的問題，難以解決問題。因此采用鍵盤鉤子區(qū)分鍵盤輸入和掃描槍數(shù)據(jù)。鍵盤人工輸入時間不均勻，而掃描槍一次數(shù)據(jù)間隔均勻，因此采用鍵盤鉤子獲得所有的鍵盤消息，如果連續(xù)多個鍵按鍵間隔小于30ms，且最后一個鍵以后連續(xù)500ms沒有輸入，就表明此串信息為掃描槍數(shù)據(jù)。
