今天没上哈..已经找到原因 是浏览器的兼容性问题 某些网站 的网址是获取不到的 不过一般的都行.. 虽然上面贴的所有代码 早都知道了 还是感谢 结贴了

也可以用IES对象，用个Timer。。

前一種方法可加多線程去創建TShellWindows，然後再去if xWin.Item[i]。。。

不仅仅针对IE 所以BHO 排除掉了 要兼容所有浏览器 所以用TShellWindows
对这个类不是很熟悉.. 用起来经常出错.. 出错一次 重新运行程序 获取出来的数目就不对头了

winsock抓包，或者你用BHO直接绑到IE上，实时获取……

那只能通过线程不断地创建TShellWindows，来获取最新的列表，并判断xWin.Item[i]是否可用
另外你可以通过抓包的方法，来获取网络访问的网址，来判断

楼上回答得不错。不过怎么才能实现监控呢？用按钮显然没有达到目的。

2楼 代码你这代码我知道 ... 看清问题.. 就是获取连接 有时候 获取不出来 .为什么! 用一个循环来换取.一直到发现 有指定URL 出现 . 但是很多突然状况.比如突然关闭浏览器 都会导致错误./然后在获取时候 连接数目就不对头了 . 你自己多测试测试看就知道了
