DllImport with c++

[Areq]

Hi,
Im writting in vc2005 sth like that:

[DllImport("func.dll", EntryPoint="TestHello",
CallingConvention=CallingConvention::StdCall)]
[System::Security::SuppressUnmanagedCodeSecurity]
extern "C" int __stdcall TestHello(char *file);

i get message "'DllImport' : attribute not found"
When i add
"using namespace System::Runtime::InteropServices;" above this code or under
#includes i get error as well: "System' : is not a class or namespace name"

This doesnt help me too:
"using System;
using System.Runtime.InteropServices;"
How to make it works?

Regards,
arq

This is all C++/CLR and not part of standard C++ and thus off-topic
here, microsoft.public.dotnet.languages.vc is a better place for further
questions.

A tip: if you've got a .h-file with the interface then instead of using
DllImport you just #include that file and add the dll as a reference to
the project.
