前言

????? 寫系列文章的時候[前言]部分變得無言了，可能來得順利了點(diǎn)吧: ) 本章中提供的封裝均是我用笨辦法從<<Hikvision 板卡網(wǎng)絡(luò)開發(fā)包編程手冊V4.7>>和<<DS-4000HC、HCS、HC+、HF、HS、MD卡的Windows編程指南V4.3>>中拷貝出來并參照VC++代碼進(jìn)行整理的，主要是針對HikServer.dll和DS40xxSDK.dll的調(diào)用封裝。

?

注意

?????本系列文章限于學(xué)習(xí)交流，注重過程，由于涉及公司，所以不提供源代碼下載，非常抱歉！！但是請大家放心，核心、實(shí)現(xiàn)以及其他能夠貼出來的代碼我都會貼出來，并且爭取盡所能的回答留言里的每一個問題，感謝大家關(guān)注，歡迎交流 :)
