Natural_Demon

hi, i would like to have some help with the following. i made a c++ class library and added this to my c# project. i would like to store some data in this class and retrieve this data when needed. this class compiles and i can find it in the c# bin folder of my project. i have done a litle reading on the subject, but it's not very clear to me. http://support.microsoft.com/kb/828736[^] http://msdn.microsoft.com/en-us/library/ms235591.aspx[^] as non universitary professional coder. i have made some MFC experience in the visual studio 2003 era, but .... : ) but i stil would like to know how it's done. can any show me how it's done? i have the following files in the c++ project. Header Files - authentication.h - resource.h - Stdafx.h Source Files - AssemblyInfo.cpp - authentication.cpp - Stdafx.cpp containing of the authentication.C file

// This is the main DLL file.

#include "stdafx.h"

#include "authentication.h"

please show how to store/set from c# a value in that c++ dll and retrieve it back to c#. kind regards and thank you for your time

Is your c++ library COM or native library? See the samples here for calling native libary from .NET and here using COM objects into managed code. :)

i don't know, that'as why i ask. i simply added a basic (not ATL, MFC or whatever) c++ class library project to my c# project.

I suppose your library is native.Follow this link for quick and easy sample how to consume C/C++ code in C#. :)
