possible duplicate: calculating size of array this question has been asked before, want confirm it. let's have following c++ function: #include <stdio.h> #include <stdin.h> #define length(a) sizeof(a)/sizeof(a[0]) int main() { double c[] = {1.0, 2.0, 3.0}; printf("%d\n", getlength(c)); return 0; } int getlength(double c[]) { return length(c);} this should return wrong value because size of return size of pointer opposed size of array being pointed at. this: template<typename t, int size> int length(t(&)[size]){return size;} i know works directly, want know if can somehow call indirectly i.e. via helper function. understand 2 possible alternatives either store length of array in separate slot or use vector, want know is: given function getlength: getlength(double arr[]) { ... } is there way compute length of arr without passing more information? the template version work. said not work? template...

i'm trying design database tables store configuration settings entities , applications associated with. can far have hit "brick wall". i'll show mean...

when have duplicates in collection, want return true, otherwise, want return false. i've got following linq query. var t = in selecteddrivers group i.value g g.count() > 1 select g.count() > 1; problem though, when there multiple duplicates, return multiple trues, , if there aren't duplicates, returns nothing (should false). problem though, when there multiple duplicates, return multiple trues, , if there aren't duplicates, returns nothing (should false). well that's easy solve: bool hasdupes = t.any(); if there multiple trues, that'll true. if there none, it'll false. but frankly, inclined write own extension method bails when finds first duplicate, rather building set of duplicates , querying set: static bool hasduplicates<t>(this ienumerable<t> sequence) { var set = new hashset<t>(); foreach(t item in sequence) { if (set.contains(item)) return tru...

when want squeeze last bit of performance code, want utilize jit optimization best can. example, marking method final easy method inlining , avoid polymorphism in critical places, etc. but couldn't find reference or list of options java programmer can use 'hint' jit compiler faster code? shouldn't have list of 'best programming' practice low latency performance jit ? the best way write jit-friendly code write straight, simple code because jit looks , knows how optimize. no tricks! also different jvm's have different jit's, in order code works of them must not rely on of them. the usual way improve jit-performance through external configuration of jvm. jvm's these days know how inline code small method calls directly, performance gains come configuring garbage collector. here effort used in avoiding having stop program while collecting, , can tweak quite bit knowledge of how underlying hardware configured , works better others...

for example: list1 = ['c', 'b', 'a'] list2 = [3, 2, 1] list3 = ['11', '10', '01'] table = [list1, list2, list3] i'd sort respect first column (list1), i'd final ordering still preserve lines (so after sorting i'd still have line 'b', 2, '10'). in example sort each list individually data can't that. what's pythonic approach? one quick way use zip : >>> operator import itemgetter >>> transpose = zip(*table) >>> transpose.sort(key=itemgetter(0)) >>> table = zip(*transpose) >>> table [('a', 'b', 'c'), (1, 2, 3), ('01', '10', '11')]

i have several uilabel s have same visual treatment. instead of redefining every single property every time, thinking of making copies of instance , changing text. how should done? another way create factory method, i'm not fond of idea. if you're willing learn three20, use ttlabel class, incorporated three20's stylesheet system, designed solve problem. however, have had trouble parsing three20's so-called documentation, think learning use library solve problem lot of overhead. my work-around problem put mini factory method, this: // example: - (uilabel *)makelabel { uilabel *label = [[[uilabel alloc] init] autorelease]; label.backgroundcolor = [uicolor clearcolor]; label.font = [uifont systemfontofsize:kmyfontsize]; label.textcolor = [uicolor bluecolor]; label.textalignment = uitextalignmentcenter; [self.view addsubview:label]; return label; } then when use method, other code gets cleaner: uilabel *namelabel = [self makelabel]; na...

i using codefirst in project. 1 of things learning how can design tables first writing classes. question - how can classify primary key [key] id, auto increment field. when record created (or row in table) primary key auto generated. how do in codefirst while writing class definition. help. public class newtable { //looking [autoincrement][key] id field etc... [key] public int id { get; set; } [required(errormessage = "title required")] [displayname("title")] public string title { get; set; } } a string auto increment? that's not gonna work. use int instead, , pk identity column default. don't need [key] attribute either; ef infer because property called id .

does intel or amd publish specifications rate @ failures in calculations can expected on cpus? suspect age , temperature dependent, surely there must kind of numbers available? i'm not interested in manufacturing errors. i'm interested in spontaneous errors due physical phenomena not related design error. whether error originates in cpu or other chip on system of interest (for example momentary voltage failure processor result in errors). i'm curious, net searching isn't yielding want. want rough ideas of left program running x hours how many spontaneous errors expect have. i'm not sure if best stackexchange site ask, perhaps electronics instead? the number zero. if calculation errors , cpu's temperature witin boundaries defined specification, have defect cpu must replaced.

we add tabcontrols our application @ runtime. each tabcontrol given viewmodel datacontext. add tabcontrols sending message main app view; message contains viewmodel used datacontext. from main app viewmodel, add tabitems tab controls sending message main app view create tabitem , add specified tabcontrol. i'd bind properties of tabitem properties of tabcontrol's viewmodel; needs done programmaticaly, of course. since tabcontrol , tabitem don't know viewmodels (only datacontext), how specify properties of viewmodel bind tabitem properties too? thanks advice... messenger.default.register<addtabcontrolmessage>(this, m => { tabcontrol tc = new tabcontrol(); tc.datacontext = m.viewmodel; // etc. } ); you can cast datacontext type of viewmodel , access properties way. tc.someproperty = ((myviewmodel)datacontext).somevmproperty;
