网址处理程序窗口和默认浏览器

Question

I've created a custom url handler in windows registry so that any link which begins with wxyz:// launches an application..

under shell/open/command , i discovered I could replace the application exe path with a url - so that if (Default) is set to "iexplore http://mydomain.com?url=%1 " and the link wxyz://thequickbrowsnfox is clicked , the users browser will goto http://mydomain.com?url=wxyz://thequickbrownfox

Considering, internet explorer might not be the users choice, how can I have the page open using the users default browser..

I just searching for the same question and I got the answer from Windows RegKey - Default Browser Application Path . However I noticed that the registry path to get default browser changed since Vista: How Does Your Browser Know that It's Not The Default .

Based on the registry value, you only get the (browser) Progid . To get the .exe path, you need to get from "HKCR\\\\<Progid>\\\\shell\\\\open\\\\command" just like the answer here Get dll directory from ProgID .

My concern is what if user change the default browser after you set the url handler? Your url handler does not point to the current default browser anymore. I afraid you need to create an application to accept the url handler (not the browser itself) and find the current default browser in the registry before you launch the browser.
