问题 I'm trying to find out all the preprocessor defines of the Visual C++ compiler (MSVC). I can do gcc -dM -E - < /dev/null on GCC to dump all the preprocessor defines. Do we have something similar with the Visual C++ compiler compiler? I'm using Visual C++ 9.0. 回答1: There is no such command. However, MSDN (both online and offline) lists all the preprocessor defines, both Microsoft specific, standard defined and ANSI defines. 来源： https://stackoverflow.com/questions/4640267/visual-c-dump

问题 There is a Microsoft specific extension, which makes it possible to define property getters and setters like this: // declspec_property.cpp struct S { int i; void putprop(int j) { i = j; } int getprop() { return i; } __declspec(property(get = getprop, put = putprop)) int the_prop; }; int main() { S s; s.the_prop = 5; return s.the_prop; } Is there any way to define property declaration attribute with clang or gcc? If I search for __declspec , all I find is __declspec(dllexport) , but I am not

问题 I'm having a problem with a tester that my application crashes in initialization. I added more logging and exception handling but it still crashes with the generic "this program has stopped working" message rather than triggering my error handling. Given my main() looks like this and has catch(...) under what circumstances would this not be triggered? try{ simed::CArmApp app(0, cmd); for(bool done = false;!done;) { done = !app.frame(); } } catch(const std::runtime_error &e){

问题 I’m trying write client application to CANoe (application by Vector).

How can i tell to the COM Server, that open the new instance in new application window? My source code: Set gCanAppA = CreateObject( "CANoe.Application") Set gCanAppB = CreateObject( "CANoe.Application") gCanAppA.Open ("Easy.cfg") gCanAppA.CAPL.Compile gCanAppA
