Cosa sbaglio???

#include "dll.h"
#include <windows.h>
#include <stdio.h>
#include <stdlib.h>

#define STRICT  
#define WIN32_LEAN_AND_MEAN 


DLLIMPORT void PlugInfo(char * name, char * autor)
{
    char * msg;
    strcpy(msg, name);
    strcpy(msg, " by ");
    strcpy(msg, autor);
    strcpy(msg, "\n");
    MessageBox (0, msg, "Hi", MB_ICONINFORMATION);
}


BOOL APIENTRY DllMain (HINSTANCE hInst     /* Library instance handle. */ ,
                       DWORD reason        /* Reason this function is being called. */ ,
                       LPVOID reserved     /* Not used. */ )
{
    switch (reason)
    {
      case DLL_PROCESS_ATTACH:
        break;

      case DLL_PROCESS_DETACH:
        break;

      case DLL_THREAD_ATTACH:
        break;

      case DLL_THREAD_DETACH:
        break;
    }

    /* Returns TRUE on success, FALSE on failure */
    return TRUE;
}

prima che analizzo il codice che errore ti da...?

[Luc@s]

Mi dice che funz nn è una funz valida.

in generale nella dll:
***********************


extern "C" __declspec( dllexport ) void PlugInfo(char*, char*);

extern "C" __declspec( dllexport ) void PlugInfo(char* name, char* author)
{
...
}


il chiamante invece:
********************

typedef void (WINAPI * FUNZEXPORT) (char*, char*)

HANDLE hLib;
FUNZEXPORT fnz;

if ( hLib = LoadLibrary ("libreria.dll") )
{
fnz = (FUNZEXPORT*) GetProcAddress (hLib, "PlugInfo");
fnz ("CICCIO BELLO", "BATUFFOLONE");
}

stai attento ai nomi ornati che il compilatore fa vebnire fuori!!!
