c# - Is this a good way to check if only one instance of a class exists without resorting to using the Singleton pattern? -

i have class in program of want 1 copy. don't want use singleton pattern though couple of reasons (* see below). know i'll have 1 copy of class because i'll 1 calling constructor. in class's constructor, want check 1 copy of class exist , throw exception if more 1 exists. code below pattern use case? public class mysingletonalternative : idisposable { private static int _count = 0; public mysingletonalternative() { int newvalue = system.threading.interlocked.increment(ref _count); if (newvalue > 1) { throw new notimplementedexception(); } } public void dispose() { int newvalue = system.threading.interlocked.decrement(ref _count); if (newvalue < 0) { throw new objectdisposedexception("mysingletonalternative"); } } } * why don't want use singleton: i want able control when class created. in traditional c# singleton pa

http - MP4 - Prepare header for pseudostreaming requests -

assuming client not support byte-range requests , therefore make requests test.mp4?startoffset=2000 how can server prepare mp4 header works requests... there bare minimum works every time or must actual original header? similarly, there way use ffprobe export original header as-is (i.e. binary format) can resent @ beginning of each request, server? thanks! edit: did digging around using atomicparsley , looking @ pseudostreamed videos via archive.org. seems "header" need reconstructed new stream. specifically, moov atom , mdat data. putting aside mdat now, there helpful libraries out there convert moov moov, or @ least make easier? no c++ please, c fine

postgresql - Ignore duplicates when importing from CSV -

i'm using postgresql database, after i've created table have populate them csv file. csv file corrupted , violates primary key rule , database throwing error , i'm unable populate table. ideas how tell database ignore duplicates when importing csv? writing script remove them csv file no acceptable. workarounds welcome too. thank you! : ) on postgresql, duplicate rows not permitted if violate unique constraint . think best option, import csv file on temp table has no constraint, delete duplicate values, , import temp table final table.

when convert excel spreadsheet csv file... convert csv file ics file... can open ics file single event inside, , accept meeting invitation, added calendar. (using app conversion) http://icsconverterwebapp.n8henrie.com/ the problem is, if put multiple rows in excel spreadsheet, final ics version opens "other calendars" can make ics file items added calendar, , not "other calendars"? i've read online seems common... not unique web app being used. here .ical looks when opened in notepad begin:vcalendar version:2.0 prodid:n8henrie.com begin:vtimezone tzid:eastern standard time begin:standard dtstart:16011104t020000 rrule:freq=yearly;byday=1su;bymonth=11 tzoffsetfrom:-0400 tzoffsetto:-0500 end:standard begin:daylight dtstart:16010311t020000 rrule:freq=yearly;byday=2su;bymonth=3 tzoffsetfrom:-0500 tzoffsetto:-0400 end:daylight end:vtimezone begin:vevent summary:xxxxxxxxxxxxxxx dtstart;tzid="eastern standard time":20140207t073000 dtend

c# - Generic type whose type parameter is an abstract base class -

let's have base class named animal , 2 derived classes named lion , tiger . , i'd have generic type named animallist<animal> contain members of animal . example: var list = new animallist<animal>(); list.add(new lion()); list.add(new tiger()); very straightforward far there's catch...i'd base class animal abstract . is, i don't want allow instance of base class created. however, making base class abstract not surprisingly results in error cs0310 (see complete example below). i did come solution: make base class non-abstract required , throw exception default (parameterless) constructor: public animal() { throw new system.notimplementedexception(); } but makes me feel little uneasy. is there better way? here's complete example illustrates scenario describe above: // public class animal {} // ok public abstract class animal {} // 'abstract' keyword causes error 'cs0310' public class lion : anim

numpy - finding cell coordinates between two points in meshgrid using python -

c++ - Clarification on postfix/prefix operators on iterators -

in accelerated c++ andrew koenig writes following code introduction templates , generic functions. code skip first element in container? or copy first iterator object before incrementing: template<class in, class out> out copy(in begin, in end, out dest) { while (begin != end) *dest++ = *begin++; return dest; } in other words, behave code?: template<class in, class out> out copy(in begin, in end, out dest) { while (begin != end) *dest = *begin; dest++; begin++; return dest; } post incrementing iterator (or else matter) may confusing doing pretty straight forward. makes copy of value, increments original , returns copy. location being referred "*dest++" same "*dest", difference after statement finishes dest refer next iteration in iteratable. the problems arise when programmers use incremented variable repeatedly in same expression. (which used brain teaser , resulting effect varies language language)

ios - How do I (the designer) test and use an iPhone in development if I don't have access to computer in which the code is being written? -

hi i'm intending have iphone app developed coder us. live in uk. when app being developed, there way can preview , use app being developed, see if designs , functionality correct? basically app equivalent of seeing developer url of website being developed. -thanks you need give developer udid of device. you can find via itunes. the developer add udid developer profile. can create install files (the file extension .ipa ) device can use. sends ipa file , use itunes install it. another approach use testflight . can register device site , developer's account on site. developer can udid web site , upload .ipa file site. once he's done that, can install app directly web site without downloading mac or pc first. note still reasonably secure because app encrypted , can run on devices included in developer's profile.

c# - Is this use of Create() right in an Entity Framework context? -

when creating object persisted database, , using create() method purpose, following snippets same? snippet 1: client client = new client(); client.name = "jonh doe"; database.clients.add(client); database.savechanges(); snippet 2: var client = database.clients.create(); client.name = "jonh doe"; database.savechanges(); according http://msdn.microsoft.com/en-us/library/gg679504(v=vs.113).aspx don't.
