ifstream app(filename, ios::binary); char Convbuf; // buffer to hold one byte at a time from the Conversion app for( int counter = 0 ; counter < 0x7000; counter++) { Conv.read(&Convbuf,1); app << Convbuf; }
ifstream app(filename, ios::binary); char Convbuf; Conv.seekg(0, ios::beg); app.seekp(0, ios::beg); Conv.read(&Convbuf,1); for( int counter = 1 ; counter < 0x7000; counter++) { app.write(&Convbuf, 1); Conv.seekg(counter); app.seekp(counter); }
I would use functions like "fwrite", "fread", "fopen", "fclose", etc: if VC++ 2010 doesn't support them, MSDN is a liar. There's an example on the MSDN page for fread.
ifstream app(filename, ios::binary); char Convbuf[0x7000]; char Convbuft; FILE * appstream; fopen_s(&appstream, filename, "w+t"); Conv.seekg(0, ios::beg); for( int counter = 0 ; counter < 0x7001; counter++) { Conv.read(&Convbuft,1); Convbuf[counter] = Convbuft; } fwrite(Convbuf, 0x7000, 0x7000, appstream); cin.get(); return 0;
are you sure you are including the files them correctly?Also, did you put: "using namespace std;" in the file, right after the includes?
Actually, I think it's because you defined the file object as ifstream, which only supports input operations. Try using ofstream for outputting.
