How would one go about connecting std::cout to a CRichEditCtrl object?

You need to derive a class from std::streambuf that outputs to a
CRichEditCtrl object. Then you replace the stream buffer that std::cout has
with your derived buffer.

class RichEditControlBuffer : public std::streambuf
{
...
};

int main()
{
RichEditControlBuffer my_buffer;
std::streambuf* old_buffer = std::cout.rdbuf(&my_buffer);
// now std::cout is connected to your buffer;
...
std::cout(old_buffer); // restore the old buffer before you quit
}

Writing the RichEditControlBuffer class is not a trivial task. You need a
good book, like The C++ Standard Library by Josuttis.

Equally, if not more useful for this would be the Langer & Kreft book.
