How could I do something like:

In an email there is a link.

c:\questpdm.exe /style-no-2898932


So that when someone click on an email link the program can jump to that record
or the program will be started if it is not started.

I guess it is similar to the way that word works when you click a doc
file but I would have to setup a file type or do something like that.


Any ideas how this could be done?
