Usage

Crete your MFC windows project and add the ConsoleWindowsApp.cpp or this source code to your project, and 

• Do Define _CONSOLEWIN in your project settings, if you want your project to work like a console and windows application. The standard output, and input will be redirected to the parent console. You can use cout, cerr, cin, printf, etc.
• Do not define _CONSOLEWIN in your project settings, and you will get a windows application. (Default)
