c# - Is there an easy way to refactor between coding practices to C#4 from C#1,C#2 and C#3 -

-

i going admit battling changing face of c# , unlearning learnt since starting out c#1.

i started years ago writing greenfield c# 1.1 code , work lot maintenance work on code written previous versions of c#. being exposed old ways of doing things hard battling unlearn code have written in past , have @ daily written in previous versions of c#. having maintain java projects doesn't similar c#1. time unlearn bad practices project deadlines hard do.

my lazy mind against me logic says if use oo , dry principles , code compiles boss happy , thinks when not simplifying code new ways of doing things.

i have started reading jon skeet's c# in depth 2ed gives code solutions specific tasks each of c#1,c#2,c#3,c#4 each time showing code examples how simplifies code finding hard remember , put practice these new methods due having still deal legacy code daily , still having balance jack of trades dev jobs.

  1. is there easy way refactor between coding practices c#1,c#2,c#3 c#4 either on fly or @ compile time , give suggests either in english language or refactor code me.

  2. is there anywhere tool or site can see changes same code between c# versions excluding jon skeet's c# in depth book?

the latest version of resharper helpful tool move c# forward in many respects quickly. point newer practices , make quicker & less painful employ them across existing code.

a couple forward-looking resharper refactorings come mind are:

  • static extension method...
  • property auto property...

also, resharper will, example, encourage use var implicit declarations possible.

coderush can same, have not used recently.

to see difference between such tools' refactorings put , started, diffing against prior revisions of files in source control comes mind.

for changes .net bcl alongside c# @stakx points out, consider digging build warnings regarding deprecated code built against newer versions of .net. once learn (as 1 example) replace uses of system.xml.xmlvalidatingreader system.xml.xmlreader, making change in other places flagged former deprecated type become quick.

what's obsolete in .net framework on msdn characterizes recent bcl deprecations since .net 1.1 , how update affected code.

c++ - Function signature as a function template parameter -

-
i'd use function signature template argument. works great classes, when try same trick function templates, msvc throws error: error c2768: 'func' : illegal use of explicit template arguments here's code: template <typename signature> void func(); template <typename r, typename a1> void func<r(a1)>(); what should make work? you cannot partially specialize function template, not supported language. can create partially specialized class template static member function, , possibly trampoline function instantiate class template , invoke static function. something this: namespace detail { template<typename signature> struct helper; template<typename r, typename a1> struct helper<r(a1)> { static void call() { // stuff r , a1... } }; } template<typename signature> void func() { detail::helper<signature>::call(); }

algorithm - What are some ways to combine a number of (potentially incompatible) sorted sub-sets of a total set into a (partial) ordering of the total set? -

-
i have sorting problem i'm pretty sure doesn't have canonical "answer" - has number of different approaches, each pros/cons. i'm interested in hearing different approaches. suppose bunch of people {p_i | i=1,...,m} ranking favorite ice cream flavors. in total there n different flavors, single person p_i ranks n_i << n flavors or familiar with. i'm interested in combining these sub-rankings plausible overall ranking of n flavors. for concrete situation: m , n both 1000 (by coincidence), , each n_i 20 . can assume there's enough overlap in flavors people rank such no flavor "isolated". again, i'm interested in hearing different ways approach this, if there isn't single clear answer. thanks! one way approach problem construct directed cyclic graph representing of constraints on ordering of elements. nodes in graph represent different elements compared , have edge first node second node if had ranked first e...

How to call a javascript function after the page loads with a chrome extension? -

-
there's function on page want call after loads. not own page, can't insert html it. can please provide specific examples how chrome extension or greasemonkey? (function submitaction() ). both chrome extensions , greasemonkey offer ways specify when script inject if executed. in chrome extension, you set in manifest : "content_scripts": [ { "run_at" : "document_idle", in greasemonkey compatible userscripts, set in metadata // @run-at document-end in both cases, have add script if want ensure resources loaded when function executed : document.addeventlistener('load', submitaction);
