i changing data-demo attribute of div element , when want check in event, shows me initial value of instead of current value. this code using: $('#showvalue').click(function(){ alert($('.value').data('demo')); }); $('.update').click(function(){ $('.value').text('updated').attr('data-demo', 'updated'); }); why happening? here's fiddle example talking about: http://jsfiddle.net/f5cpm/ thanks. the jquery .data() functions aren't supporting html5 dataset functionality, rather load in html5 dataset data own data collection. in consequence updates dataset changing attribute not reflected in jquery internal data collection. in other words, either need consequently use dataset.demo , $().data("demo") or $().attr("data-demo") . advantage of second being cross browser of course , part of jquery if you're using jquery rest of application.

i looking @ this question and, try find mistake, went php manual seen 2 options : curlopt_ssh_private_keyfile file name private key. if not used, libcurl defaults $home/.ssh/id_dsa if home environment variable set, , "id_dsa" in current directory if home not set. if file password-protected, set password curlopt_keypasswd. curlopt_sslkey name of file containing private ssl key. op of question uses curlopt_ssh_public_keyfile guess should uses curlopt_ssh_private_keyfile instead of curlopt_sslkey , don't know difference between options. so here comes question : what difference between curlopt_sslkey , curlopt_ssh_private_keyfile ? well, found difference between ssh , ssl in it security question. thomas pornin answered : ssl , ssh both provide cryptographic elements build tunnel confidential data transport checked integrity. part, use similar techniques, , may suffer same kind of attacks, should provide si...

i want know when methods including key words stated in topic called. for example: – tableview:willselectrowatindexpath: – tableview:didselectrowatindexpath: - (bool)tableview:(nstableview *)atableview shouldselectrow:(nsinteger)rowindex when willselectrow method called? method mean including key words "will" "did" , "should" similarly, there viewdidappear , viewwillappear. it's obvious when viewdidappear method called. viewwillappear 1 quite beyond me. hope help;) willselectrow: tells delegate specified row selected. didselectrow : tells delegate specified row selected. should: returns whether table view should allow selection of specified row. it works same way viewdidappear , viewwillappear. viewdidappear: view has appeared. viewwillappear: view appear. you can learn more in apple documentation. i hope helped !

say have following code: class { public: a() {} int f(void*, void*) { return 0; } }; template <typename t> class f { public: f(int(t::*f)(void*,void*)) { this->f = f; } int(t::*f)(void*,void*); int call(t& t,void* a,void* b) { return (t.*f)(a,b); } }; a; f<a> f(&a::f); f.call(a, 0, 0); well works can call function how example have array of these without knowing type? i able call class f function callback. i'd use static or c function , done wanted experiment calling c++ member function. think of i'm trying delegates in c#. i've seen sophisticated implementations in boost , other places want bare minimum, no copying, creation, deletion etc required simple callback can call. is pipedream? advice appreciated. i think bare minimum implementation following: std::vector<std::function<bool(int, int)>> my_delegate; you can add many different type...
