Please help.  I am proficent in C# and the new microsoft .net framework, but I have to access a third part dll using com/interop with .net and I am unable to successfully get the results i need from using platform invoke and the third party dll does not provide a type library so I cannot use the type library importer tool.

I can however create all my logic in C++ and then create a RCW to allow me to acces my new object in C#, but I have never ever create a true c++ com object or dll and don't know where to begin.

Can someone please point me in the right direction whether it be books or web examples.  All I need is a simple example and I can move foreward.

Thanks

Jim

You will find lots of COM objects with source code in unmanaged C++ at codeproject.com:
http://www.codeproject.com/com/
There is a special "beginners" section inside.
Good luck,
Jaime.
