Wow. Did you know WTL 7.1 was released back in December? Sheesh. I been hobbling along with a version of WTL 7.0 I hacked to get it working under VS.NET 2003 and I didn't know about WTL 7.1 until now. It has a nice set of bug fixes, VS.NET 2003 compatibility, and works under CE too. Nice! Microsoft should either put more resources behind WTL or make it public domain so WTL developers like me can keep updating it.
FYI, WTL is an extension of ATL, a set of C++ templates for writing lean and mean Win32 software.
