c# - Modifying a property to automatically resolve "Cannot modify the return value" error -

i'd know if there's built-in or easy implement way handle "cannot modify return value because not variable" problem. let's have class: myclass { rectangle _rect = new rectangle(1, 2, 3, 4); public rectangle rect { { return _rect; } set { _rect = value; } } } this i'm trying do: rect.width += 20; // , error pops the usual approach instead: rect = new rectangle(rect.x, rect.y, rect.width + 20, rect.height); but there has way automate it, right? , don't mean adding bunch of properties myclass rect_width , such (because have 9 rectangles in real class implementation, , bad), make line of code work: rect.width += 20; there's nothing can circumvent problem, since rectangle-class immutable , that's way intended work. however, expose method encapsulates creation of new rectangles: myclass { rectangle _rect; public rectangle rect { { return _rect; } set { _rect = value; } } public void addwidth(int...

java - How to get month number from Calender -

line holds month name given user. display month number. example: june -> 6 present code: string line="june"; int monthno = integer.parseint(gregoriancalendar.class.getfield(line.touppercase()).get(line))+1; system.out.println(monthno); what best method this? edit: using existing calender classes java's calendar api not best api around. many people therefore changed use http://www.joda.org/joda-time/ quasi alternative standard. if application simple, think hard-coding map of names pointing numbers easiest , efficient solution (assuming, string in fact user input, otherwise, use enum suggested). alternatively, can use date format .

std::list double linked list. doesn't mean should possible remove item list having access iterator? maybe question wasn't clear enough. #pragma once #include <list> typedef std::list<int> intlist ; typedef intlist::iterator intiterator; class inthiddenlist { private: intlist list; public: intiterator addint(int x) { list.push_front(x); return list.begin(); } }; int main() { inthiddenlist a; intiterator = a.addint(5); // how go deleting 5 list using "it"? } yes, notionally it's possible. however, standard library not allow (it requires container , iterator erase). however you're in luck: boost provides boost::instrusive ( http://www.boost.org/doc/libs/1_54_0/doc/html/intrusive/list.html ) capability want.

android - search items in database and display dropdown list -

i have following app architecture (generalized simplification): main layout consists of actionbar custom view , scrollable tabs , , viewpager hosting multiple listfragments . each listfragment has own set of data (1 row = imageview + textview ) loaded sqlite database. in actionbar's custom view have "search" edittext . when user starts typing something, i'd perform "on-the-go" search in database , display matching names (those names should clickable) in form of dropdown list. saw examples how perform search in listview , nothing related database search. so question is: how display database search results dropdown list , refresh anytime user adds or removes character? you need implement autocompletetextview . allows suggestions user typing. can bind data searched for, using adapters . this should solve problem. an example might helpful can found here .

this question related scenario.i have datagrid editable. 1 of columns drop down list when in edit mode. out of data grid have 2 radio buttons (open,all).
