Hi,
Sorry, the question will about C++ (maybe its a shortest way to get an answer)

I try to write a very simple DLL

#include <stdafx.h>
#include <windows.h>
#include <tchar.h>
#include <sddl.h>

extern "C" __declspec(dllexport) VOID ExecMe(char* fileName)
{
	MessageBox(NULL,_T(fileName),_T(fileName),MB_ICONINFORMATION);
}

When I try to execute it - the application crash... when I use hardcoded string

MessageBox(NULL,_T("test"),_T("filename"),MB_ICONINFORMATION);

all works fine...

any help please! :)
