Unmanaged C++ Dll To Managed

[micho3]

Here is my problem!
I'm trying to use a Unmanaged dll (Use of MFC) into a C# project. But I know I have to wrap it before I can use it! So I've tried to wrap it without any success ! I'm new in this kind of prog and I would like some help !!!

Here is a sample of the code of the unmanaged .h I want to wrap!

#ifdef DLL_EXPORT
#define DLL_TYPE __declspec(dllexport)
#else
#define DLL_TYPE __declspec(dllimport)
#endif
 
class DLL_TYPE OptiEditParam
{
    public:
        void *param;
        OptiEditParam( void );
        ~OptiEditParam( void );
        int Edit( char *fichier, char *buffer, int &nbChar );
};

There is other class but I want to be able to use OptiEditParam.Edit first, then I'll go for other class!

I first create a Win32 Dll, Am I Ok? Plz Help me!!
Here is the code. BTW, It compile #1...

#include "stdafx.h"
#include "OptEbout1.h"
 
#ifdef _MANAGED
#pragma managed(push, off)
#endif
 
BOOL APIENTRY DllMain( HMODULE hModule,
                       DWORD  ul_reason_for_call,
                       LPVOID lpReserved
                     )
{
    return TRUE;
};
 
OptiEditParam::OptiEditParam()
{
};
 
OptiEditParam::~OptiEditParam()
{
};
 
 
int OptiEditParam::Edit(char *fichier, char *buffer, int &nbChar)
{
    return 0; //Is this Ok%?!!
};
 
#ifdef _MANAGED
#pragma managed(pop)
#endif

Then I created a Class Library And here is what I tried! But I can't get nothing except these Errors

Error 1 error C2062: type 'char' unexpected c:\documents and settings\administrator\mes documents\visual studio 2005\projects\optiwrapdll\optiwrapdll\OptiWrapDll. h 56
Error 2 error C2062: type 'char' unexpected c:\documents and settings\administrator\mes documents\visual studio 2005\projects\optiwrapdll\optiwrapdll\OptiWrapDll. h 70
