vb.net - Using shadowed methods/fields in an overriden method -

-

suppose had following code:

class normalemployee      protected pay decimal;      protected shared basepay decimal = 300d      protected overridable sub updatepay()          pay = basepay + .....do something......      end sub end class  class seniornormalemployee   inherits normal employee     protected shared shadows basepay decimal = 500d;     protected overrides sub updatepay()          pay = basepay + .....do different....     end sub end class  function main() integer     dim newemployee normalemployee = new seniornormalemployee()     newemployee.calculatepay()     return 0 end function

i know due polymorphism, calculatepay() base class called. question is: why calculatepay() use basepay base class , not derived class? object being stored inside base class "container", though uses derived classes version of method, when goes check basepay shouldn't @ base class's version?

furthermore, behavior same when calling shadowed methods overrides method? there way make field "overridable"?

thanks help!

the problem using shadows keyword makes code use varible of base class, when reference base class. since used polymorphyism , newemployee defined normalemployee, basepay 1 of base class. more information, check here.

this question has answer here: what's mongoose error cast objectid failed value xxx @ path “_id”? 7 answers even though has been asked many times because entity has no valid objectid field. i came across situation objectid set value can casted objectid still error. the schema: var serviceschema = parammongoose.schema({ servicename:{ type: parammongoose.schema.types.objectid , ref: 'servicenames',required:true } }); pseudo code: servicefromdb=new service({servicename:'some name'}); servicefromdb.servicename='000000000000000000000001'; servicefromdb.save(function(paramerror,paramdata){ if(paramerror){ console.log('but but...',servicefromdb,paramerror) } }); the output of code is: but but... { servicename: 000000000000000000000001, _id: 55079a90286f49280364f78b } { [casterror: cast objectid faile...

[C++][SFML 2.2] Strange Performance Issues - Moving Mouse Lowers CPU Usage -

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
