open file

[MPrestonf12]

#include "iostream.h"
#include "fstream.h"
#include "stdafx.h"

int getdir();

int getdir()
{
int i;
ofstream out("C:/Matt/text3.txt");

if(!out) {
		MessageBox(NULL,"Cannot open output file","Error",MB_OK);
		return 1;
}

for(i=0;i<256; i++) out.put((char) i);

out.close();

	return 0;
}

im using MVC++ and i get errors. This worked on my old compiler but not MS's. What am I doing wrong here? Thanks
