6.保存并用IE打开,请允许加载Active控件,如果不出问题则调用成功
注意事项:
1.SSOcx.SetDeviceInfo("192.168.1.108",37777,0,"admin","admin");注意修改成你的摄像机的IP地址、端口、通道、用户名、密码
2.大华的dll要注册成功,检查有没有注册的方法:打开注册表,搜索classid号,如果有表明OCX控件注册成功,classid号为:30209FBC-57EB-4F87-BF3E-740E3D8019D2
3.改方法试用于IE,其它浏览器不行
4.第一次用IE打开一定要加载控件,如果IE阻止控件会导致调用失败。如果IE阻止加载控件,请在Internet项目->安全->自定义级别 中将ActiveX控件和插件下的所有项都启用
