Another project open-sourced by Microsoft
The Microsoft Windows Toolkit Library (WTL) has been just been made open source, which is nice.
Although this won't affect me in the slightest (still slowly working my way through C++ for Programmers by Leen Ammeraal), it's encouraging and I'm sure that the relevant communities will be happy.
What is the WTL?:
Windows Template Library (WTL) is a C++ library for developing Windows applications and UI components. It extends ATL (Active Template Library) and provides a set of classes for controls, dialogs, frame windows, GDI objects, and more.
