I prefer to use the API function OutputDebugString. It isn't as 
powerful as the printf type of commands, but it sends a string to a 
seperate debug window. This also has the great effect that I'f you're 
testing multiple programmes at the same time you get the output in 
order in the same window. It works for GUI and console programmes.

You can get a debug string viewer (for free) at www.sysinternals.com
