w332 · #1 22-Jul-2004, 21:33

Im going crazy over this piece of code, it compiles but the exe is huge
and it doesent copy corectly, the file in program files is 0 kb.. (so empty)
could annybody please tell me what to change or maybe use another
command.. (what i basicly want to do is copy the file that is being
executed to another directory)
thanx for help !!!

Code:

CPP / C++ / C Code:

const char *src = "\\instal.exe";
ifstream input(src,ios::binary);

const char *dst = "c:\\Program Files\\myprogram.exe";
ofstream output(dst,ios::binary);

output <<input.rdbuf();

I just built and ran the program and it worked fine:

CPP / C++ / C Code:

#include <fstream>
using namespace std;

int main()
{
    const char *src = "text.txt";
    ifstream input(src,ios::binary);

    const char *dst = "text1.txt";
    ofstream output(dst,ios::binary);

    output <<input.rdbuf();

    return 0;
}

How big is the file you're trying to copy? I tested it on a file 7,225,832 bytes.
