6.保存並用IE打開，請允許加載Active控件，如果不出問題則調用成功
注意事項：
1.SSOcx.SetDeviceInfo("192.168.1.108",37777,0,"admin","admin");注意修改成你的攝像機的IP地址、端口、通道、用戶名、密碼
2.大華的dll要注冊成功，檢查有沒有注冊的方法：打開注冊表，搜索classid號，如果有表明OCX控件注冊成功，classid號為：30209FBC-57EB-4F87-BF3E-740E3D8019D2
3.改方法試用於IE，其它瀏覽器不行
4.第一次用IE打開一定要加載控件，如果IE阻止控件會導致調用失敗。如果IE阻止加載控件，請在Internet項目->安全->自定義級別 中將ActiveX控件和插件下的所有項都啟用
