First of all i might make mistake by posting here, but i really don`t know where to start.
I`ve seen programs that recognize a special type of URL. For example DC++ recognizez the dchub:// type of URL. When you click on the dchub://ip_of_the_hub (link wichis in a webpage), DC++ automaticaly starts and enters on that hub.
I want to know how this is done (i smell like it would be from the registry) because i want to start making an application that includes this feature.
