trying out dojo datagrid control on alternate xpage (so not impact production) existing view, utilizes readers fields in documents. i've got rest service implemented (xe:viewitemfileservice) , connected dojo datagrid fine (from 8.5.3 up1 controls). i have 2 scenarios of user visibility (via roles in readers field, assigned nab group definition): all documents visible (user a). user can see documents, works fine one. user b can see documents. viewpanel control works fine, once it's in dojo datagrid, has values documents user b should see, remaining x (difference between correctly visible , total document count) rows populated "..." (non-values). inspecting rest service's output via pathinfo yields correct documents user b; take sign , makes me think dojo datagrid what's misbehaving. actual question : how can suppress generation of unnecessary rows? i've tried implement marky roden's approach , got lost on manipulation of how can contro

why headfiles of main.cpp need include .h headfiles contain declaration instead of implementation? can write class in cpp file including both declaration , implementation , include cpp file main.cpp headfile? how can include headfile not in project? technically, header file (or other file decide #include ) can contains absolutely whole makes complete c++ program. what happens when compiler (technically, part of compiler package called "c preprocessor") sees #include "somefile.h" in source-code takes file, , "pastes" main file being compiled. "pretend" preprocessor opening headerfile, marking , pasting main file. the point header files avoid copying , pasting same bit of c++ several source files. example, declaration of class can put header file myclass.h , actual implementation myclass.cpp file, , part of program using myclass need include header. header files not part of project typically surrounded angle brackets, #in

what have <div#graphicsclosebox> nested inside <div#catbox> . it's supposed when click , class changes back. cannot use toggleclass because there form input inside box, clicking form messes things up. $('#catbox').click(function() { $(this).removeclass('cat'); $(this).addclass('cat2'); }); $('#graphicsclosebox').click(function() { $('#catbox').removeclass('cat2'); $('#catbox').addclass('cat'); }); if want example check http://codepen.io/rtro92/pen/mihlu pretty straightforward. know problem in 2nd function, can't target #catbox. thanks! your problem event propagation (a.k.a. "bubbling"), functionality events in 1 dom element "bubbles" parents, unless event told not so. in other words, when clicks <div#graphicsclosebox> , classes correctly added , removed specified. directly after, click event on <div#catbox> triggered, - sin

i know , read abstract class , interface 1 point never understood that, use of class cannot instantiated. can use normal class , virtual method instead of abstract class? happen when instantiate base class? you typically use abstract class when have set of common functionality shared between derived classes. is, cannot use interface because want provide default functionality. take @ system.io.stream class. class provides common base functionality, requires specific types of streams implement members in order function. these members tagged abstract , indicates compiler , runtime there no suitable base-class implementation. non-abstract class derives abstract class must override inherited abstract members, class implements interface must implement members defined on interface. in stream example, read() method abstract, readbyte() method not -- because readbyte() can implemented in terms of call read() . (although not optimally, why readbyte() virtual, more eff

i select bunch of rows table a, along results of aggregate functions avg(a.price) , avg(a.distance). now, select query takes bit of time, don't want run 1 query rows, , other averages. if did that, i'd running query select appropriate rows twice. but looking @ postgresql window function documentation ( http://www.postgresql.org/docs/9.1/static/tutorial-window.html ), seems using window function return results of aggregate functions want use alongside returned rows means every single row returned contain results of aggregate functions. , in case, since aggregation on rows returned main select query , not subset of rows, seems wasteful. what performance implications of returning same avg() many times, given i'm selecting subset of rows in doing aggregate queries across entire subset? in particular, postgres recompute average every time, or cache average somehow? by way of analogy: if @ window function docs , pretend depname 'develop' every row returned se
