Use Dll in VC++ .NET

[mengfrank]

Hi. I created utility.DLL and an EXE ATL projects with VC++ .net.
I want to call my utility.DLL in my EXE.
Because it doesn't work after I did "Add reference" in the project, I
imported the dll with
#import "..\path\utilit y.dll"
When I open the "utility.tl h" file, it is
///////////////////
#pragma once
#pragma pack(push, 8)
#include <comdef.h>

namespace utility{
//
// Forward references and typedefs
//
struct __declspec(uuid ("9cc48c69-c070-4309-aae1-6ff24c97f196"))
/* LIBID */ __utility;
} // namespace utility
#pragma pack(pop)
///////////////////////////////////
There is more stuff in "utility.tl h" when I used VC++ 6.0.
At least, it should give me the Interface.
How can I create an Instance without an Interface?
Maybe I am running in the wrong direction.
How to use unmanaged dll with VC++ .NET?
Thank you for your help in advance,
Frank
