You cannot call Windows API functions directly from ASP.  You can only call ASP functions or load a COM component that implements the IDispatch interface (and an ActiveX control fits this definition) and load it using CreateObject.  You can then call properties and methods on the object's interface.

In you case, the easiest way would be to wrap your C API functions in an ATL ActiveX component.  Visual C++ V6 makes this fairly easy.  Once you've done this your component will work just like any other component in ASP.

As far as an example, forget it for 40 points.  It's not difficult to do this but there are a lot of things to worry about.  Check the VC++ documentation for how to create an ATL component, it's in there.

If you're new to this whole thing, a good book on this subject is "Professional COM Applications with ATL".  By Li and Economopoulos and published by WROX Press.
