Re: [Dev-C++] Offtopic: Advice on GUI to learn

[Daniel G. <sp...@ho...>]

Personally I'm at a bit of a quandary (thanks Dictionary.com) as I'm sure 
many new Windows programmers are. Do we work hard to learn the old APIs or 
do we hold off for the WinFX api?

Does anyone know of a good site with WinFX information? Yes I could google 
it but there's no guarantee I will find the best site. Google isn't a real 
world programmer.
