i developing game i'd have multiple scripts implement same structure. each script need run in own scope code doesn't overlap other scripts. example: structure.js function oninit() { // define resources load, collision vars, etc. } function onloop() { // every loop } function clickevent() { // clicked me } // other fun functions now, lets have: "badguy.js", "reallyreallybadguy.js", "otherbadguy.js" - above in terms of structure. within game whenever event takes place, i'd invoke appropriate function. the problem comes down efficiency , speed. found working solution creating engine each script instance (using getenginebyname ), doesn't seem ideal me. if there isn't better solution, i'll resort each script having own unique class / function names. i.e. badguy.js var badguy = new object(); badguy.clickevent = function() { } i don't think need create new scriptengine every "guy". ca...

list<paymenttype> paymentoptions = _paymentmethods; _paymentmethods public property , i'd filter copy of , store in variable paymentoptions list<int32> noinvoice = new list<int32>(){ 16, 4 , 6 }; foreach (paymenttype pt in paymentoptions) { if(noinvoice.contains(pt.id)) { paymentoptions.remove(pt); break; } } but if run second time, variable _paymentmethods not contain removed item anymore. it seems go reference instead of value... prefer not copy list array should use linq or there other way? edit: have now: list<paymenttype> paymentoptions = shopcontroller.currentshop.paymentmethods; list<paymenttype> paymentoptionsfiltered = new list<paymenttype>(); if (havetofilter) { list<int32> noinvoice = new list<int32>() { 16, 4, 6 }; foreach (paymenttype pt in paymentoptions) { if (!noinvoice.contains(pt.id)) { paymentoptionsfiltered.add(pt); ...

initially php programmer , using joomla build websites . build websites in joomla in few days. i learning java spring hibernate last 3 months , have build simple user registration logins , members area using spring mvc , hibernate annotation etc. now want ask whether onwards should use spring mvc build site because have learned or me in future. because still feel same site can build in few days in php is case in future can come on same level php can build simple site in java in few days or no matter experience have java still going take longer php always can java cms make life easier because want bye php. mean if want make 5 page portfolio website can build in java cms in 1-2 days if "simple website" mean normal page categories, articles , navigation (i.e. not web-application), yes: building grounds java + spring + hibernate overkill (i.e. low-level tools, you'd have build lot yourself). i'd stick tools built specific task, namely kind of cms s...

i have been learning java spring hibernate mvc 3 months , got pretty idea of . have not understood jcr means. i mean e.g in simple webiste in spring mvc part can done in jcr jcr alternative persistence mechanism used in place of jpa (hibernate), hides jdbc application. in theory, java classes have in model might remain same have now. however, if classes in model came because needed model lower-level data structures jpa, these classes might not needed jcr. you'd need reason replace existing use of jpa jcr. example, may have discovered using jpa requires jumping through lot of hoops , doing things you'd not need do. having said that, jcr has advantages , capabilities not otherwise found in jpa: jcr supports structured data, unstructured data, , in between. jcr allows flexible schema , can nosql-ish. jpa structured, fixed schema. jcr hierarchical - use cases extremely hierarchical, , doing relational model can difficult/expensive jcr has built-in events mo...

i want have timer update global variable every 10 sec, put timer in global.asax.cs: void application_start(object sender, eventargs e) { timer atimer = new timer(); atimer.interval = 10*1000; atimer.tick += atimer_tick; atimer.start(); } void atimer_tick(object sender, eventargs e) { // update data } but weird thing nothing happen after 10 sec. wonder if possible that? thanks in advance. use system.timers.timer instead of system.windows.forms.timer the former uses elasped event handler , function expected anywhere in application. latter tailored winforms , should used on form1_load() not on application start.

is there way use trace.axd handler tracing single page on site? i'm trying monitor in production, don't want tracing output page, want limit output specific page. edit: prefer have running record of requests aggregated, trace.axd does. you can enable page-level tracing (it not use trace.axd, output still in page) trace.isenabled can enable page-level tracing programmatically, can show trace information in page if conditions met (for instance have parameter in querystring can yourpage.aspx?displaytraceinfo=true ). way not risk having users see trace information in page.
