Program Url

[IsWorking]

Hi,

I would like to intercept url when it's clicked in a Word document. Simple idea at the beginning, after... very boring one. Searching on web, and different sites, i've found examples, but nothing very useful for my problem. One way to do that is to listen to url buffer of IE, why not.
The problem is that my url is a program one (they call like that on viewed web pages), that's to say instead of launching a web page from internet and show it in IE window, this special kind of url, launch a program whose path is in window register.

This url look like that :
cel:\\ (next : program parameters) Follow\Earth (...)

cel is for the path in Windows register. After that, there are parameters for the program itself.

I would like to catch url string when the Word user selecte it.
How can I detect with a Vb progam that url is launch in Word ?

I've tried an alternative solution : I've changed the path in windows register with the path of a program of mine. When i clicked on url in Word, my program is launched, but no way to get additional information from url !

I don't know a lot about network and url processes, if someone can help me !
