VB webbrowser 中打开https网页 弹出安全警报 怎样在程序中实现‘点击确定’这个功能

Question

需要在程序中实现，不是降低安全级别 ，设置信任站点之类的 打开HTTPS类安全网页，就因为弹出安全警报，网页就会等待 单击确定 就像邮箱中的一样，我想是不是可以在弹出对话框时 在程序中是先单击确定的功能，请高手赐教！谢谢

Answer 1

以前也遇到过.没解决..不过好像他只弹出一次...
换成用XMLHTTP来他仍然弹出来...估计不是WebBrowser的设置问题...

Answer 2

用IInternetSecurityManager接口直接设置webbrowser自己的的安全级别

用一个API TIMER进行每隔半秒或0.1秒监控，发现就关闭（进程内）
或者另做一个EXE进行关闭
