i evaluating if possible leverage c++11 features replace logging macros without run-time additional cost. i come out demo: enum class loglevel { fatal = 0, dfatal = 1, error = 2, normal = 3, verbose = 4, debug = 5 }; constexpr loglevel log_compiled = loglevel::normal; loglevel log_runtime = loglevel::error; #ifdef ndebug constexpr loglevel log_fatal = loglevel::fatal; #else constexpr loglevel log_fatal = loglevel::dfatal; #endif template <loglevel l, typename std::enable_if<(l <= log_fatal)>::type* = nullptr> void log(std::string message) { std::cout << "fatal level: " << (int) l << " message: " << message << std::endl; exit(0); } template <loglevel l, typename std::enable_if<(l>log_fatal && l <= log_compiled)>::type* = nullptr> void log(std::string message) { if (l <= log_runtime) { std::cout << "level: " << (int

so code below on website i'm revising [links pulled database now] works perfect , prints out matching row , column html. there column short names[name2, varchar] , auto incrementing integer column[id] match. function rainmaker($fname) { $connect = new pdo('mysql:host=localhost;dbname=weather;', '******', '***'); $sql = $connect->query('select `link` `satellite` `name2` = "'.$fname.'"'); while ($result = $sql->fetch()){ $urllink = $result['link'];} $linky = fulllinkedthumbnail($urllink,150); print $linky; } further down.... <td align="center"><p><?php rainmaker('ato'); ?></p></td> success! image shown on site. however, every variation of via id fails (1064 error: variable $urllink empty) or doesn't print out image link (site works, except images aren't shown). $sql = $connect->query('select `link` `sat

i've searched around , haven't found solution sounds reasonable me or seems relevant specific problem (even here on stack overflow). the problem simple: have of work needed custom checkboxes on cell of list view; need detect hover on/hover off draw hot images. these images set control's state image table, want change subitem state on hovers , clicks. i tried using nm_hover , after doing work things working didn't work. upon further research, seems issued if lvs_ex_trackselect on, don't want; want handle hovers, not select on hover! i looked using nm_hottrack , nm_activate , give me half answer: not know when items stop being hovered on (to cold-ify last hot item). i found codeproject project wacky things internal tooltips. don't want touch internal data structures @ all. my list view subclassed. require common controls 6. need run on xp or newer (though vista-specific option acceptable future). do have options here? thanks. since have

i'm pulling json information , i'm left huge nested array. an example schema follows: 'messages' => '0' => 'title' => 'foo' 'body' => 'bar' '1' => ... 'stories' 'foo' => 'bar' in scenario, want grab contents starting '0' , '1' , of children (title , body). 'stories' disregarded 1 depth higher 0 , 1. 0 , 1 automatically generated list , integer value dynamically go high need be, different. cheers! foreach($array['messages'] $key => $val){ if($key == 0 or $key == 1){ $new_array[] = $val; } } $new_array have relevant content. assumes you're referring messages part of array. if there other sub arrays want parse/manipulate have adjust condition in foreach loop. you can parse/manipulate $new_array needed, , ignore content don't need in $array .

i'm working on c++ project where, among other things, have interface few pure virtual methods. problem arises when try implement interface - intellisense doesn't seem agree derived class's method declaration. example of such method: // dll_export -> #define dll_export __declspec(dllexport) // iplayer dll_export virtual const grid& getgrid() const = 0; declaration in 1 of derived classes: // human : iplayer dll_export const grid& iplayer::getgrid() const; the error keeps nagging me - "intellisense: declaration must correspond pure virtual member function in indicated base class". code compiles without errors , runs fine, of "problematic" methods jobs expected during run time. worth mentioning error disappears if remove iplayer:: scope qualifier in derived class. wanted keep there readability reasons. also, not proficient in c++ there wrong example i've provided. minimized example: struct c { virtual void f() = 0; };
