按照SDK Demo，可以登陆到DVR，可以看视频，也可以录像（在开发目录Bin中已经有MP4的文件了）
但，找btnSearchq却不到录像文件。。。。。。。
哪位兄弟做过类似的，请帮忙看看，谢谢！





private void btnSearch_Click(object sender, EventArgs e)

        {

            //listViewFile.Items.Clear();//清空文件列表 



            CHCNetSDK.NET_DVR_FILECOND_V40 struFileCond_V40 = new CHCNetSDK.NET_DVR_FILECOND_V40();



            struFileCond_V40.lChannel = iChannelNum[(int)iSelIndex]; //通道号 Channel number

            struFileCond_V40.dwFileType = 0xff; //0xff-全部，0-定时录像，1-移动侦测，2-报警触发，...

            struFileCond_V40.dwIsLocked = 0xff; //0-未锁定文件，1-锁定文件，0xff表示所有文件（包括锁定和未锁定）



            //设置录像查找的开始时间 Set the starting time to search video files

            struFileCond_V40.struStartTime.dwYear = 2014;

            struFileCond_V40.struStartTime.dwMonth = 7;

            struFileCond_V40.struStartTime.dwDay = 1;

            struFileCond_V40.struStartTime.dwHour = 1;

            struFileCond_V40.struStartTime.dwMinute = 1;

            struFileCond_V40.struStartTime.dwSecond = 1;



            //设置录像查找的结束时间 Set the stopping time to search video files

            struFileCond_V40.struStopTime.dwYear = 2014;
