问题 I create the class that inherited CWinApp and this class has a timer (use a window timer). When PC go sleep mode and wake-up, timer callback is called exact time of wake-up. I want to make to not call the timer callback when PC is resuming from suspend. So I tried to use WM_POWERBROADCAST message. But this message didn't catch in PreTranslateMessage() API. Also I tried SetWindowLong() with my own API but still didn't catch the WM_POWERBROADCAST message. Is there any way to get WM

问题 Consider the following class: class Foo { enum Flags {Bar, Baz, Bax}; template<Flags, class = void> struct Internal; template<class unused> struct Internal<Bar, unused> {/* ... */}; template<class unused> struct Internal<Baz, unused> {/* ... */}; template<class unused> struct Internal<Bax, unused> {/* ... */}; }; The class outline above compiles and functions as expected when tested on VC++ 2010 and Comeau C++. However, when Foo is made into a template itself, the above snippet breaks under

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I'm looking to write a bit of software that will end up drawing a human frame (which can be configured with various parameters), and the plan is to have some sort of clothing placed on the dummy. I've looked at Blender, and OpenGL libraries as well as other rendering and physics engines, I'm not looking for you

问题 I'm trying to compile the SymbolicC++ library in VC++ 2010 Express (there is special VS project in the distribution), but it gives a lot of errors in system headers , related to operator, . For example: 1>C:\Program Files\Microsoft Visual Studio 10.0\VC\include\xlocmon(410): error C2593: 'operator ,' is ambiguous For this code in a system header: if (_Str[0] < _E0 || _E0 + 9 < _Str[0]) _Str2 += '-', ++_Off; Why? How to compile it? 回答1: Apparently, SymbolicC++ has overloaded operator, in such

问题 I am trying to compile my program but it wouldn't link at all. I have specified the path to the boost lib files and the linker still complain. Here's the linking error I got: 1>Edproj.obj : error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAABVerror_category@12@XZ) 1>Edproj.obj : error LNK2001: unresolved external symbol "class boost::system::error_category const & __cdecl boost
