ActiveX Wrapper

I have a DLL that I want to use in an ASP script, however it's not an ActiveX DLL component.
I get a "DllRegisterSever entry point was not found" error mesage when trying to register
it with regsvr32.exe.

So, the solution to this problem seems to be creating an ActiveX wrapper, so I can use
this DLL. The only problem is I have no idea how to create such a wrapper.

Can anyone suggest a tutorial creating an ActiveX wrapper with MSVC++ 6.0?

I just have to pass a string as input, then return a string as output.
