Advanced console programming?

I'm wondering how to do things with the standard output besides cout << x. How do you write to the console somewhere besides the end of the stream? For example, I've seen video decoders that will display a simplified version of the video file in the console window. How do you back up the place where you write to the standard output? I'm interested both in C/C++ and .NET. I can't seem to Google up any good tutorials. ~BenDilts( void );
