c++ - Using extern template class with STL classes -


i'm trying limit template instantiations of std::map, std::multimap, , std::vector 1 object file in attempt improve compile , link times. far understand, reason can't use

#include <vector> extern template class std::vector<int>; std::vector<int> myobj;

is vs10's header contains definitions of members, they're treated inline compiler, , instantiated anyways. assumption correct work if remove function bodies header? if so, happen have such header, , able share it?

i've tried listing members so

extern template std::vector<int>::vector(); // works extern template std::vector<int>::~vector(); // no effect

and while ctor removed, dtor still defined according dumpbin. reason that? because reason dtor considered inline , ctor not?

it's standard stl data structures implemented in header files, isn't vs10 specific. why want limit 1 object file?

there problems splitting templates between headers , source files - can search that.

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
