if classes below not templates have x in derived class. however, code below, have to use this->x . why? template <typename t> class base { protected: int x; }; template <typename t> class derived : public base<t> { public: int f() { return this->x; } }; int main() { derived<int> d; d.f(); return 0; } short answer: in order make x dependent name, lookup deferred until template parameter known. long answer: when compiler sees template, supposed perform checks immediately, without seeing template parameter. others deferred until parameter known. it's called two-phase compilation, , msvc doesn't it's required standard , implemented other major compilers. if like, compiler must compile template sees (to kind of internal parse tree representation), , defer compiling instantiation until later. the checks performed on template itself, rather on particular instantiations of it, require compiler able resolve

suppose have following tree: boost::property_tree::ptree tree; tree.add("1.2.3", "value-1"); tree.add("1.2.3.4", "nested-value"); tree.add("1.2.3", "value-2"); tree.add("1.2.33", "other-value"); which has following serialized info form: 1 { 2 { 3 value-1 { 4 nested-value } 3 value-2 33 other-value } } is there method remove nodes having provided (possibly nested) path? i.e.: remove(tree, "1.2.3"); boost_assert(!tree.get_optional<std::string>("1.2.3") && !tree.get_child_optional("1.2.3")); with result info form: 1 { 2 { 33 other-value } } looking @ ptree docs , source code i've found several methods remove immediate children of tree (nested children not accounted). also, there several methods subtree it's full path (even if nested). since th

i have database, columns image , alttag. want use them in laravel blade view. try this: {{ html::image('images/{{ $item->image }}', $alt="{{ $item->alttag }}") }} but syntax isn't correct. if echo image , alttag this: <h1>{{ $item->alttag }}</h1> then correct. wonder wrong in code. you used blade syntax in php string. watch compiled blade templates see did go wrong. in short. try this: {{ html::image('images/'. $item->image, $alt = $item->alttag) }} or equally short: {{ html::image("images/{$item->image}", $alt = $item->alttag) }}

i have written custom "edit account" script allows wordpress user update wordpress account. working great, except can't seem find way update user's nicename, doubles user's url slug (via get_author_posts_url function). causing issues because when user changes name, slug still contains original name - not new one. i know sanitize_title function generate new nicename, don't know how verify unique , modify if not before entering db. wondering built-in functions wordpress has handle this. know can write own script this, rather use wordpress functions. couldn't find anywhere in wp documentation. thanks! here function have written in lue of built in function: function new_user_slug($string){ //generate new slug $slug=sanitize_title($string); //make sure slug unique $result=mysql_query("select * wp_users user_nicename='$slug'"); if(mysql_num_rows($result)==0){ return $slug; }else{ $counter=2; $ki

i have navigation controller pushes view-controller ( parent ) contains uipageviewcontroller ( pages ). used pan/swipe gestures switch between children of page-view-controller. however, can no longer pop parent -view controller using swipe gesture left border of screen, because interpreted gesture in pages . is possible accomplish swipe-to-pop when left-most view-controller shown? two ideas: return nil in pageviewcontroller:viewcontrollerbeforeviewcontroller -> doesn't work. restrict touch area, described here . or there more straightforward way? i had same situation @smallwisdom, handled differently. i have view controller a push on top of navigation controller's stack. view controller a contains horizontal scroll view stretches way left side of screen right. in scenario, when wanted swipe screen pop view controller a navigation controller's stack, ended doing scrolling horizontal scroll view. the solution pretty simple. inside view c

what difference between creating object , without "new"? example: thing = new thing(); vs. path filepath = path.get("c:\\......) in first example understand when instantiating object, "new" allocating memory object , memory location referenced something. my text book says " create path object" using second example. difference how object stored or memory allocated? not sure why create object way. in second case using static method internally creating object or passing reference existing object. common pattern particularly when apis wish hide internal implementation (as case here).

i have std::map<std::string,foo> , need find() elements when instead of std::string , have const char* . however, map.find("key_value") won't work, need std::string . so, need map.find(std::string{"key_value"}) , create temporary std::string (with allocation , de-allocation) each time, making potentially inefficient. reasoning correct? if yes, how can improve situation? i think using wrapper around const char* key map has own comparison function , can cheaply wrapped around const char* , no need allocations. idea? (note mapped values not copyable, movable). you can avoid temporaries using 0-terminated strings , custom comparator map. still, using unordered_map yield better indexing performance. an alternative (much better), using wrapper, think. there std::reference_wrapper task. still, first rule of optimisation: not it. second rule: not it. third rule (only experts): after measurement , careful consideration, might anyway.
