Try this (tried with .NET 2):

(rdnzl:enable-rdnzl-syntax) (rdnzl:import-types "System.Windows.Forms" "FolderBrowserDialog") (setq dlg (rdnzl:new "System.Windows.Forms.FolderBrowserDialog")) [ShowDialog dlg]

This problem was the cause that made me recompile RDNZL-cpp under VS2005. If you look into StdAfx.cpp, you'll see how I changed the apartment state, but I don't know if it would work under

VC.NET-2003.

So, do I understand correctly that you already experienced these problems with the DLL compiled with VS2003?

Yes. But this is not related to VS2003 itself. It just happened that I needed to modify the CPP code (to change the default apartment state) and that I only had VS2005 under the hand; hence I had to port the code to the new CLI/C++ interface.
