1、文档供参考，可复制、编制，期待您的好评与关注！ 本实例实现超市摄像头定时监控系统。运行本例后，在“定时监控设置”处设置监控的星期及时间，单击【保存】按钮，将“定时设置”参数数据保存到数据库中。系统在运行到定时时间后，程序将自动进行监控。如图所示。另外，监控的录像文件和图片文件保存在D盘根目录中，命名格式为系统当前日期。图 超市摄像头定时监控实现过程（1）新建一个项目，命名为Ex13_10，默认窗体为Form1，添加一个类文件（.CS），用于编写视频类。（2）在Form1窗体中，主要添加一个PictrueBox控件，用于显示视频。（3）主要程序代码。视频类中主要程序代码如下： / / 开始录像
2、/ / 要保存录像的路径 public void StarKinescope(string path) IntPtr hBmp = Marshal.StringToHGlobalAnsi(path); SendMessage(hWndC,WM_CAP_FILE_SET_CAPTURE_FILEA,0, hBmp.ToInt32(); SendMessage(hWndC, WM_CAP_SEQUENCE, 0, 0); / / 停止录像 / public void StopKinescope() SendMessage(hWndC, WM_CAP_STOP, 0, 0); Form1窗体主要代码
3、如下： private void timer1_Tick(object sender, EventArgs e) string strTime=; /星期一 if (chk1.Checked & Convert.ToInt32(DateTime.Now.DayOfWeek)=1) strTime = DateTime.Now.ToString(HH:mm); DateTime date = Convert.ToDateTime(mtxt1.Text); if (strTime = date.ToString(HH:mm) video.StarKinescope(d: + DateTime.To
