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
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 --------------------编程问答--------------------
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... --------------------编程问答-------------------- IDocHostShowUI::ShowMessage --------------------编程问答-------------------- 您能不能说的详细点 --------------------编程问答-------------------- 用IInternetSecurityManager接口直接设置webbrowser自己的的安全级别 --------------------编程问答-------------------- http://www.codeproject.com/KB/atl/vbmhwb.aspx --------------------编程问答--------------------

或者另做一个EXE进行关闭
