Thread: Switching from Borland To Microsoft

Im a very beginner coder and I used Borland C++ BuilderX to write a program. Since C++ BuilderX doesnt do GUI stuff(But is awesome for writing code) I downloaded Microsoft Visual C++ Express which is great for the GUI stuff. Now when I try to include my BuilderX coded program in Visual C++ I get a boatload of errors, there were no errors in BuilderX. I think most of the errors are related to ifstream and sprintf.

heres some snippets of how I coded it

Code:

#include <fstream.h>
#include <stdio.h>
#include <conio.h>
#include <iostream.h>
#include <stdlib.h>


ifstream logfile( "1000.csv" );
char log[] = "file.bin";

...

logfile.getline(buffer, 250);

...

fstream outbin(log, ios::out|ios::in|ios::binary);

...

outbin.seekp(0x00000932);

...

outbin.put(BinOut[i][n]);

...

sprintf(del,",");

In the program I deal with 2 files and I used different methods to open each, on the one I used ifstream and the other I used fstream. Im very new to this stuff so I dont know what a lot of this means but I figure stuff out as I go and the program works in a C++ BuilderX console setup.

Your builder seems to be ancient, that code is pre-1998 C++ (i.e. before the very first C++ standard).

Code:

#include <fstream>
#include <cstdio>
#include <conio.h>  // This is not standard C++
#include <iostream>
#include <cstdlib>

using namespace std; // This is pretty bad form, but probably better than tracking down the hundreds of errors.

You may need to convert over to the standard headers:

Code:

#include <fstream>
#include <cstdio>
#include <conio.h>
#include <iostream>
#include <cstdlib>
using namespace std;

I don't think Microsoft Visual C++ Express has a conio.h though.

i tried the "using namespace std" already and I just got this

File1.cpp(7) : error C2871: 'std' : a namespace with this name does not exist


am I allowed to post my whole source? its like 263 lines long

also I put the includes in so thats probably why they are weird, i read "learn C++ in 21 days" and it said to use those

You need to drop the .h from your C++ headers file, too. (That excludes <conio.h>.) Read swoopy's post more carefully.

heres my whole program that I made in BuilderX with the includes that swoopy posted

You're missing a double quote after stdafx.h:

Code:

#include <fstream>
#include <cstdio>
#include <conio.h>
#include <iostream>
#include <cstdlib>
#include "stdafx.h"
using namespace std;
