Redirecting stdout
In graphical Windows applications, a handy trick for testing is to redirect stdio, stdout and stderr to a text based console window.

To achieve this is VS C++, simple put the following code somewhere near the top of your application. You need only do this once per thread:
AllocConsole(); 
freopen("conin$","r",stdin); 
freopen("conout$","w",stdout); 
freopen("conout$","w",stderr);
