I would like to announce a new open source C++ library for Windows GUI development that may be of interest to users of this forum. The library is known as OpenAFX and is an open source equivalent of MFC. It is compatible with the Windows SDK and Visual C++ Express (which do not include MFC), as well as the Open Watcom C++ compiler. It is dually licensed under the Mozilla Public License and the Sybase Open Watcom Public License and may be used for both open source and commercial development. The project's web site, from which the library can be downloaded, is located at http://openafx.sourceforge.net.
