Using server-side OCX with ASP.Net Web Service

[Lee]

I am using a library supplied by a third-party vendor. Although the
library has no UI, the vendor supplies it as an .OCX control.

I need to utilize this library in an ASP.Net Web Service. My Web
Service does not expose the OCX control's functionality directly, but
utilizes the OCX for its own internal purposes.

What is the best approach here?

Since I am more familiar with old VB6 than with .Net, I was thinking of
wrapping the OCX with an ActiveX server written in VB6. This ActiveX
server would provide the hidden form that the OCX requires. I would
then utilize the ActiveX server from ASP.Net via interop.

Does this make sense? How would I do this using just .Net -- without
getting VB6 involved.

TIA!
