    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.

    I tried the includes that swoopy posted and it didnt work, among the 37 errors I am getting

    .\File1.cpp(7) : error C2871: 'std' : a namespace with this name does not exist
    .\File1.cpp(12) : error C2146: syntax error : missing ';' before identifier 'logfile'

    You don't need pre-compiled headers. Go to the project options or properties and find the pre-compiled headers option and turn it off, then delete the #include "stdafx.h" line. When you create a new project, choose Win32 Console Application and check the Empty Project box on one of the tabs in the wizard to make sure that it isn't set in the future.

    The problem is that the compiler ignores everything before the #include "stdafx.h", so if you use that you need to put it first.

    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;
