最近分析了一下Google Adsense投放的广告，呵呵，使用mshtml很简单的代码得到Google Adsense的广告的地址，没什么用处，呵呵，只是玩玩而已，声明不会对Google Adsense进行作弊，不然会被Google给kick out的，呵呵……
至于原理很简单：Google利用Javascript在目的网页上生成一个name为google_ads_frame的iframe，该iframe中的网页上包含一个id为aw0的超级链接（代码中分析的是按钮型的广告，其中只有一个超级链接，多个超级的原理也是一样的，超级链接的id的格式为“aw+序数”），这些用mshtml都很容易得到。
需要提到的是广告中的超级链接的类型（用mshtml分析）为HTMLAnchorElementClass。如果不知道类型怎么办，可以用this.doc.all.item("aw0", null).GetType().ToString()来得到，这是使用mshtml时的一个技巧。
