calling activeX dll from asp

Ok i'm stilll new to activeX dll......just learn about it couple of days ago..
how do u actually call a dll from asp pages? can someone provide me with some samples as well as steps to follow to instantiate the object in asp. Do i have to register the component first in the server?

You call a component with:

Code:

---

Server.CreateObject("progID")

---

The component has to be registered on the server - you can also use MTS/COM+.
