i need share common functionality between 2 static classes: public static class class { public static void classmethod() { sharedmethod<object>(); } //ideally private method internal static void sharedmethod<t>() { } } public static class genericclass<t> { public static void genericclassmethod() { sharedmethod<t>(); } } is there better design here? internal last choice, method sharedmethod has no significance outside 2 classes. requirements: i can't combine them single class, need them separately, 1 generic , other not. the classes need not strictly static, shouldn't instantiable or inheritable. sharedmethod can fall in either class, doesn't matter. this workaround doesn't meet 3 requirements (which impossible imo) made same functionality wanted. i ended using single class marc suggested in comments. had generic class nested inside non generic class act generi

java - Feedback on my Binary Search Algorithm -

-
i have written binary search algorithm, seems bit different other peoples i've seen. hoping community give me feedback whether or not i'm missing something, or doing wrong way. binary search: import java.util.arrays; public class binarysearch { public int[] numbers = new int[] {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20}; /** * @param num * @param key * * function recursively searches sorted array of integers, finding specific number (key). * search looks @ midpoint of array, checking see if midpoint number being sought, * if not, depending of whether sought number greater than, or less than, midpoint * function copies upper, or lower, half of array , passes recursive * function call. * */ public int performsearch(int[] num, int key){ if(num.length == 0){ system.out.println("array empty"); return 0; }else{ int mid; in

c++ - How to store the vector.begin() iterator of template type in thrust? -

-
when attempt assign variable iterator, error: expected ";" , vec thrust::device_vector<my_type> , j int , , my_type template type: for (thrust::device_vector<my_type>::iterator = vec.begin(); < vec.end(); += j) foo(i); is correct way loop on vector? declaring i correct type? standard containers use iterators traversing through collection of other objects (i.e. elements), since iterator abstract concept implemented in standard containers, can implement iterators in following way: typename thrust::device_vector<my_type>::iterator = vec.begin(); (it; != vec.end(); = it+j) foo(*it); here's reference stl containers: http://www.cplusplus.com/reference/stl/

COM C#, How to use C++ to call COM -

i used online example of c# com , call through c++. following c# com code, 1 interface "icalc" , 1 class "calc". namespace comlib { [guid("f40d7bc9-cf53-4613-aa5e-f269ad73808f")] [interfacetype(cominterfacetype.interfaceisidispatch)] public interface icalc { [dispid(1)] long factorial(int n); } [guid("8ee38f2e-75be-4b45-87b6-3f6d15fdbbc5")] [classinterface(classinterfacetype.none)] [comsourceinterfaces(typeof(icalc))] [progid("mycalc")] public class calc : icalc { long icalc.factorial(int n) { long fact = 1; (int = 1; <= n; i++) fact *= i; return fact; } } } the following code in c++ call this function. worked. however, confused code in second line. "icalcptr" come from? or mechanism? coinitialize(null); comlib::icalcptr pcalc; hresult hres = pcalc.createinstance(__uuidof(comlib::calc)); if(failed(hres)) printf("icalcptr::createinsta

jquery - Using $.css() without selector increases performance? -

-
jquery allows use $.css() method directly , pass raw dom element first parameter. example, if want set 'a' width of mydiv, jquery allows syntax: (option 1): var elem = document.getelementbyid('mydiv'); var = $.css(elem, 'width'); instead of (option 2): var = $('#mydiv').css('width'); option 1 not require selector, , appears rely on global jquery object instead of creating new one. can't find documentation in jquery api or online method. assume performance increase, when jquery objects required in animations. reason why shouldn't using method? thanks! edit: perf tests show option 1 bit faster. doesn't seem there's reason not use $.css() directly. answers! yeah, first 1 faster. can css value. i made perf test here: http://jsperf.com/jquery-css-signature may revise , test out other options. now facts set, @ these level of performance optimisation, don't think worth overhead. go more clear/main

c++ - strlen of a char array is greater than its size. How to avoid? -

-
i defined array: char arr[1480]; now, file, read 1480 chars , put arr (by doing arr[i]=c). know 1480 chars because use while loop read 1 char ar time (istream.get()) , stop when incrementing index = 1480. however, after that, strlen(array) , returns 1512. how come? happens in occasions, not in occasions, though every time read file, read 1480 chars. my doubt 1 char might occupy more 1 unit (units returned strlen(arr)). if so, how can fix this? thanks ps: asked problem earlier pointer gets garbaged, , cause when have buffer (arr) of length > 1480. the array size must include string terminator. since read size of array can't (and don't) add string terminator. strlen function, , other string functions, uses string terminator character find end of string. if it's not there continue until finds it. if may have no more 1480 characters in string, should have array of size 1481, last being string terminator '\0' .

The regex for a simple case -

-
can give me regular expression validate string _ _._ _ _ numbers, point @ 3rd position. well, ^\d\d\.\d\d\d$ (or ^\d{2}\.\d{3}$ ), depending on regex engine you're using. depending on sort of matching function you're using, may not need ^ , $ (start , end) markers either. if engine older 1 doesn't recognise \d , can use [0-9] instead.

wpf - is it possible execute a method in the view when change a property in the view model with MVVM pattern? -

-
i open dialog in application , close view when property in view model changed. so thinking in ths way: 1.- in view.axml.cs (code behind) have method named close() execute method close of view. 2.- in view model have property called viewmodelclosing, bool. 3.- view, in way, don't know how, binding property of view model , execute method in code behind when property changed. is possible that? thanks. Álvaro garcía the simplest , imo best way accept icommand in viewmodel controller. since viewmodel should not dependent on view or matter viewcontroller, follwoing solution uses dependency injection / inversion of control. the delegatecommand (aka relaycommand) wrapper icommand i have kept code minimum focus on solution. public class viewcontroller { private view _view; private viewmodel _viewmodel; public viewcontroller() { icommand closeview = new delegatecommand(m => closeview()); this._view = new view();
