Internet Explorer_server COM Object Interface

There is a commercial application (which I will disclose in private) that implements the Internet Explorer_server COM Interface ([login to view URL]). I need a small class written and tested (on my platform) in VB.NET 2005 that will (consistently) interface with this object and return the [login to view URL] (from the appropriate application). I've tried doing this myself but it's a bit tricky, so I'm looking for someone with a little bit of experience working with COM, or at least the willingness to explore all the options. I know people that have done this already, so I know it's possible. The code will probably consist of less than 20 lines, so it should be easily/quickly implemented. And, I can provide the code I've already written (in private) as a reference.
