I've created new ATL\WTL project in Visual Studio 2010.

I've got red lines under CAppModule,CMessageLoop and etc. with error

identifier is undefined

How can this be solved?

You need to include the proper headers. For example CAppModule is defined in atlapp.h so you need #include <atlapp.h>.

    You should mention that `` is part of the Windows Template Library. I had to go open 20+ search terms just to find out about this. I'm a noobie at WTL/ATL by the way. – tom_mai78101 Oct 02 '12 at 14:49
  • @tom_mai78101, sorry I just assumed that anyone working on a WTL app would have the headers available. – Mark Ransom Oct 02 '12 at 15:20
