I''m have some issues getting fstream to output a file in hex.
I''ve tried both of these setups (plus a million others, it seems):
ofstream ofile;
string buffer;
ofile.open (filename.c_str(), ios::binary);
buffer = "Test Text\n";
ofile << hex;
ofile.write(buffer.c_str(), buffer.length());
ofile.close()
and:
ofstream ofile;
string buffer;
ofile.open (filename.c_str(), ios::binary);
buffer = "Test Text\n";
ofile.setf(ios::hex);
ofile.write(buffer.c_str(), buffer.length());
ofile.close()
These both output:
Text Test
in plain text... it bothers me, ''cause at some points during my fumblings I got it to output as hex. Any ideas as to how I can fix this would be very greatly appreciated. Thanks!

If you write ascii characters in hex, doesn''t text editor display them as ascii characters?

Well, I was trying to read them in VS .Net (which showed them to me in Hex mode at a couple of points). Also tried it with numbers and it just shows up as text.
I believe that you need something like:
ofstream f(filename.c_str());f << setw(2) << hex;for (int i = 0; i < buffer.size(); ++i) f << (int)(buffer[i]);
quote:buffer = "Test Text\n";ofile.setf(ios::hex);ofile.write(buffer.c_str(), buffer.length());
The ios::hex manipulator applies to numbers only (think about it). You are feeding the stream a const char*.
You should instead feed it each and every character of your string, casted to int, like Beer Hunter suggests...
