In writing any non-trivial application, help from the community of developers if often fundamental. In my own dev projects I have been using various forums and discussion sites.Following are links to what I think among the very best:Microsoft Discussion Groups (web interface to Microsoft's public NNTP newsgroups)MSDN ForumsGoogle Groups (web interface to a vast set of NNTP newgroups)CodeGuru ForumsDev Shed ForumsGameDev.Net Discussion ForumsCprogramming.com ForumsC++ Home ForumsOSDev ForumsThe above sites often deal with lots of different technologies and programming languages but what ties them all is that they all have vast forums dealing with C/C++ on the Windows platform. There are obviously other very good discussion sites dealing with other technologies (.NET languages, web technologies, various application servers, etc.) but I'm not listing them here.Did I miss any good discussion board?
