> I'm looking for some guidance on how to Internet Explorer options using functionality available in D. I am trying to make the following work but cannot since I don't have a copy of wininet.lib:

I located wininet.dll and build from it a .lib file using implib. However when attempting to compile the program the following error occurs:

 Error 42: Symbol Undefined _InternetSetOption
--- errorlevel 1

Is there something I am missing?
Any advice is appreciated.
