I added a reference to the COM object SHDOCVW.dll.  It of course
created the Interop.shdocvw.dll file.  As I understand it this is for
the Runtime Callable Wrapper, so .NET can call on the COM object with
interoperability.

Now, my problem is that it says when I try and load the design of the
.cs file:

" File or assembly name Interop.SHDocVw, or one of its dependencies,
was not found."

However, I can see it in the Debug folder just as soon as I make a
reference to it.  I do not understand what it wants.  Please help me.
Thank you.
