[help required] CD-Rom autostart

I wrote a simple program that whenever a CDROM is mounted it copies all files into my harddrive. Now I want to add an extra functionality but I don not know how :( Here is my question : you know, when you mount a CD windows automatically pops a dialog that with which program we want to open the CD.. some programs add themselves to this list, so I want to do the same thing too! I will appreciate any help and thanks for your answers
