简单三层+EF

【实例简介】 ------------------------------------- 1. 实现预览、抓图(BMP、JPEG)、客户端录像、云台控制(2014-7-4) 2. 设备通道号在界面上手动输入，64路以下NVR的IP通道一般从33开始 3. bin文件夹下为已编译的可执行程序（Release版本） 4. SDK日志保存路径："C:\SdkLog\"（2014-7-4） 【注意事项】 ------------------------------------ 【库文件】里的HCNetSDK.dll、HCCore.dll、HCNetSDKCom文件夹、PlayCtrl.dll、SuperRender.dll、AudioRender.dll、ssleay32.dll、libeay32.dll、hlog.dll、hpr.dll、zlib1.dll、log4cxx.properties等文件均拷贝到bin文件夹下。HCNetSDKCom文件夹（包含里面的功能组件dll库文件）需要和HCNetSDK.dll、HCCore.dll一起加载，放在同一个目录下，且HCNetSDKCom文件夹名不能修改。 3. 如果自行开发软件不能正常实现相应功能，而且程序没有指定加载的dll库路径，请在程序运行的情况下尝试删除HCNetSDK.dll。如果可以删除，说明程序可能调用到系统盘Windows->System32目录下的dll文件，建议删除或者更新该目录下的相关dll文件；如果不能删除，dll文件右键选择属性确认SDK库版本。 4. 如按上述步骤操作后还是不能实现相应功能，请根据NET_DVR_GetLastError返回的错误号判断原因。
