仿腾讯QQ和Skype 通过URL触发自己的程序2010-08-22 vckbase 谢红伟如果你电脑中装有QQ,在IE地址栏输入:“tencent://Message/?menu=yes&exe=&uin=13231462”然后[回车],立即可以与我的QQ建立临时会话,如下图:

Skype也有类似的功能。到底是如何实现的呢?看MSDN中有这么一段话:The IURLSearchHook interface is used by the browser to translate the address of an unknown URL protocol. When attempting to browse to a URL address that does not contain a protocol, the browser will first attempt to determine the correct protocol from the address. If this is not successful, the browser will create URL Search Hook objects and call each object"s Translate method until the address is translated or all of the hooks have been queried.IURLSearchHook接口被浏览器用来转换一个未知的URL协议地址。当浏览器企图去打开一个未知协议的URL地址时,浏览器首先尝试从这个地址得到当前的协议,如果不成功,浏览器将创建在系统中注册的URL Search Hook对象并调用每一个对象的Translate方法,直到地址被转换或所有的URL Search Hook都尝试过。也就是说,我们可以注册一种目前不存在的协议(类似HTTP),当浏览器遇到新的协议时会自动调用Translate方法来翻译我们的协议,甚至激活我们自己的程序。
