Full screen console applications

May 19th, 2006

Hey,

I have a problem using Visual Studio 2005. In the MSDN library it says there is a function called SetConsoleDisplayMode. This function though is not in the 2005 library. I'm assuming its an old reference from VS 2003. Does anyone know how to tell a console program to switch into full screen mode?

Any help is appreciated.
- Daniel

Here's a code snippet which I found.
