i have singleton class, string method's name, , want invoke method class. class foo { private static foo instance; private string name; private foo() { } public static getinstance() { if(instance == null) instance = new foo(); return instance; } public foo setname(string name) { this.name = name; return this; } private void bar() { system.out.println("a"); } public void execute() { // invoke "name" method here } } foo.getinstance().setname("bar").execute(); how can this? use foo.getclass().getmethod(name, null).invoke(this, null) . you'll need change second parameter getmethod if have several methods same name different signatures, , invoke if method accepts parameters.

i have 2 nsmanagedobject (person , car) , relationship "not inverse" between them. relationship not inverse. i have 2 viewcontrollers, first 1 has tableview shows each instance of person object , second has table view shows every car of person. first view controller shows name of person , number of cars of person. all works fine issue appear when try delete car of person. think remove object correctly: [_person removecarssobject:car1]; but issue appear when being in second view, remove car, , go first view: number of cars doesn't refresh , app crashes. when add car , go second view works , 'number of cars' increases. when run app again, car deleted. why think way delete object correct. i've realized app works number of cars going take value 0, otherwise app crashes. i hope can me, thank you! update: i’ve changed code, , reload data of table view in - (void)viewwillappear:(bool)animated{ this way can see proper data in table view, bu

i trying write resourcecach should have thread loads , unloads objects of different types. started idea of having thread member variable , list wich std::string s represent path files load / unload. there method called work() should executed thread. enaugh talk. the question is: how init thread inside of constructor? .h class resourcecach { public: resourcecach(); ~resourcecach(); void init(); bool stopthread(); void load(std::string path); void unload(std::string path); private: thread m_worker; // ptr? reference? right? vector<std::string> m_toload; vector<std::string> m_tounload; void work(); }; and cpp should (this not work) resourcecach::resourcecach() { init(); } resourcecach::~resourcecach() { } void resourcecach::init() { m_worker(resourcecach::work, "resourcecach-thread"); } void resourcecach::work(){ } bool resourcecach::stopthread(){ if (m_worker.joinable()) { m_worker.jo

i trying achieve following when user starts app: 1- if user not logged in show login screen. 2- if user created account , there valid token show start screen. to end have implemented custom authenticator based on tutorial found here http://www.udinic.com/ . the code works, issue shows current activity ui briefly switches add account ui provided accountauthenticator. how can fixed this? this code: @override public void onstart(){ super.onstart(); gettokenforaccountcreateifneeded(accountgeneral.account_type, accountgeneral.authtoken_type_full_access); } @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.main); maccountmanager = accountmanager.get(this); } /** * auth token account. * if not exist - add , return auth token. * if 1 exist - return auth token. * if more 1 exists - show picker , return select account's auth token. * @param accounttype * @param authto

here's finished code, need little advice , how insert desired messagebox. needs display finished sequence vertically, thanks. using system; using system.collections.generic; using system.linq; using system.text; using system.windows.forms; class program { public static double fibonacci(double n) { double = 0; double b = 1; (double = 0; < n; i++) { double sum = a; = b; b = sum + b; } return a; } static void main() { (double = 0; < 12; i++) { console.writeline(fibonacci(i)); } } } if want show messagebox, try: static void main() { list<double> nums = new list<double>(); (double = 0; < 12; i++) { nums.add(fibonacci(i)); } messagebox.show(string.join(system.environment.newline, nums)); } a console application can display messagebox if you've included right libraries, , looks include system.windows.forms , should set. although honestly

when use y-axis label formatter, points don't plot correctly. point "6.8" plotting above 6.8 line. also, y-axis ticks not equal intervals (7.8, 7.5, 7.3, 7.0, 6.8, 6.5). removing label formatter clears issue. know work-around can keep label formatter? with label formatter: http://jsfiddle.net/3tkdt/1/ without label formatter: http://jsfiddle.net/3tkdt/2/ label formatter: yaxis: { labels: { formatter: function () { return highcharts.numberformat(this.value, 1); } } } using numberformat function on y-axis labels wasn't idea. rounding tick marks , representing intervals incorrectly. removed label formatter.

hello please me one, stent table bal table with stent_size 20 both table, current_status = co_qc_comeplete , status = added, 5 records, instead in select query got 50 recrods.. confused.. i want 5 records of stent table join of bal table , want 5 records bal table. can me create select query one.. thanks in advance.. edit : select * stent sd left join bal bd on sd.stent_size = bd.stent_size sd.current_status = "co_qc_complete" , sd.stent_size = "20" , bd.status = "added" select * stent sd left join bal bd on sd.stent_size = bd.stent_size sd.current_status = "co_qc_complete" , sd.stent_size = "20" , bd.status = "added" returns 50 records because takes of bal (10 records shown) , joins stent (5 records shown) stent_size = stent_size. (each bal record paired 5 stent records) there nothing unique data save ids, can trouble when joining these tables. thinking little more, , th

i know if know android framework conventional applications. example, framework rails can see mvc pattern. see answer here overview of android's limitations, give idea of why mvc pattern on android has not yet emerged: http://www.quora.com/is-there-any-standard-mvc-framework-in-android-application-development-if-not-is-it-worth-developing-one after having posted answer have gone ahead , built fully-featured app using single-activity architecture. allowed past major ux limitations mentioned while being able have arbitrary complexity in controller hierarchies (parents children sub-children etc.). overall worked out great, have build out specialized components (ie: custom stack mechanism) store/restore state in way plays nicely android's own activity/fragment lifecycle patterns. there limitations around fragment animations had pull our hair out @ times, required more custom component workarounds. ie: animations show both outgoing , incoming fragment on-screen @ same
