    maybe


    #include <fstream.h>

    ifstream File("MyFile.ext", ios::binary);


    I believe it's something like this. Might be wrong though... I still use the old C file pointer way

    Thumbs up

    Not sure if this is what your after, but in its most basic form, i'd do it like this:

    #include <fstream.h>

    main()
    {
    char ch;
    char filename[20] = "c:test.txt";
    int mode = ios:ut;
    fstream fout(filename, mode );
    cout << "Ready for input, use CTRL+Z to end" << endl;
    while ( cin.get( ch ) )
    {
    fout.put( ch );
    }
    fout.close();
    return(0);
    }

    fout.close(); is important, miss it and you could **** up your whole hd.

    to open the file:

    #include <fstream.h>

    main()
    {
    char ch;
    char filename[20] = "c:test.txt";
    int mode = ios::in;

    fstream fin(filename, mode );
    if (!fin)
    cout << "Unable to open file";
    while ( fin.get(ch) )
    {
    cout << ch;
    }
    fin.close();
    return(0);
    }
