BinaryWriters are .NET classes, and they are wrappers around the
streams only. They may not be specifically wrapping around Standard C+
+ streams, but they definitely wrap around something conceptually
similar. If you set the constant ios::binary in the constructor for
fstream, you get a binary writer.

if you can send me your code i can revert back with a complete code.
