i'm using react-native-router-flux react-redux , think should ask question here, correct me if i'm wrong. i have activitymodal container call show whenever there api call or similar thing want show modal. i'm calling this: actions.refresh({key: 'activitymodal', visible: true}); show , actions.refresh({key: 'activitymodal', visible: false}); hide. this works i'd rather make more elegant solution. added 2 actions (for show , hide) , added there lines of code , works i'm not sure if that's correct way (and without using reducers, action - i'm new redux). i'm thinking way this: adding helper functions i'll have actions.refresh calls , importing them need access activitymodal visibility. please tell me or suggest me correct way this? thanks! edit: succeeded i'd confirm if it's practice. here did: containers/logincontainer.js ... this.props.showactivitymodal(); // calling on button press ... actions/activit

i trying log changes in variable values in ssis generated biml. managed create event handler writes everytime variable changes value. when log use parameter value set "system.variablevalue". pass parameter (togheter variablename , packagename) storedproc , write in log table. problem (but not always) seems parameter not has value. see new line in db log table means evnt correctly raised , handled seems parameter empty. strangest thing values logged correctly not always, not same variables, not same packages, rather, in quite random fashion. could problem fact several variables change value @ same time (some contention on db) ? doubt it, because row gets written on db. tried write, value, 'new value = ' + ? is, appending parameter value fixed string. fixed part gets written correctly but.. no value. name of variable changed value written correctly. any idea due to? as workaround tried use ready-made logging facility of ssis in case in message column of syss

please take @ code below, sorry bit lengthy, did best reproduce problem minimum example (there live copy of it). there have metafunction returns size of string literal, , constexpr function wraps it. when call functions in template parameter gcc (5.4, 6.2) happy it, clang (3.8, 3.9) barfs "non-type template argument not constant expression" in test body on strsize(s) . if replace str_size<s> both compilers happy. questions are: whether problem clang, or code? what way make compile on both clang , gcc constexpr function? template<size_t n> using string_literal_t = char[n]; template<class t> struct strsize; ///< metafunction size of string literal alikes /// specialize strsize string literals template<size_t n> struct strsize <string_literal_t<n>>{ static constexpr size_t value = n-1; }; /// template variable, convenience template <class t> constexpr size_t str_size = strsize<t>::value; /// same constexpr func

is there way establish in compile time if template function specialized? for example, assume following function: template<size_t n> void foo(); i want test if foo<42> specialized. note declaration above doesn't contain default implementation. i tried sfinae couldn't find condition on function compiler cannot deduce declaration. any thoughts? thanks is there way establish in compile time if template function specialized? with function... don't think so. but if create functor, can add static const member ( is_specialized , in following example) can give information #include <iostream> template <std::size_t n> struct foo { static constexpr bool is_specialized { false }; void operator() () const { std::cout << "- generic (" << n << ") foo struct" << std::endl; } }; template <> struct foo<42u> { static constexpr bool is_specialized { true };
