i've general question saving data in angularjs. there opportunities save data in json files , kept them when changed site? mean when change site "persons" "home" , go "persons" created data remain in list of persons? how can resolve this? or possible webapi written in java/c# example? know this? my example @ current push data in list of json data: $scope.additem = function (item) { $scope.list.push(item); $scope.item = null; }; it depends on how long you're looking keep data around, there few options. if want share data between app, while user on website, of angular "services" (factory, service, provider) work singletons. more information on differences, check out answer: angularjs: service vs provider vs factory if looking persist data across user visits, should consider using localstorage. there great angular local storage module here: https://github.com/grevory/angular-local-storage

i have select query: select sample_number, sample_type, storage_address, external_number systmx2.tm2_samples and need add 2 more columns results of .net syntax code end like" select sample_number, sample_type, storage_address, external_number, somecodearound(storage_address) rowposition, somecodearound(storage_address) columnposition systmx2.tm2_samples the row , column positions based upon fall in 9 x 9 grid. 9 numbers columns across top , 9 numbers rows down side. lab specimen box hold 81 vials. every vial has number 1 81 , last 3 characters of storage_address value similar fr2-s01-r01-001 or fr2-s01-r01-081. vial number 1 in column 1 , row 1; vial 81 in row 9 column 9. .net code row take last 3 character of storage_address , test decimal. tryparse(storage_address.substring(storage_address.length - 3), value) and take value , convert with: cint(decimal.truncate(((value+ 9 - 1) / 9))). and column code is: (value + 9) - (

it simple question didn't find answer... have tab separated files many rows , different number of fields in each row. this: a1_j a2_f a3_f a10_g a8_t a2_e a2_j a6_h a8_o a9_g i want print fields start a2, not whole line, matched fields.like this: a2_f a2_e a2_j i tried awk, no success. i use grep this: grep -o 'a2_[a-z]' file the -o switch means matches printed, each on separate line.

is possible append style during @postconstruct of component, example commandbutton. change style class here no way because need dynamic values. i tried following resets style of button uiviewroot root = facescontext.getcurrentinstance().getviewroot(); commandbutton button = (commandbutton)root.findcomponent("form:btn1"); button.setstyle("background-color: red;"); you can assign style commandbutton dynamically using expression language: <p:commandbutton ... style="#{bean.buttonstyle}" ... />

in solution working on, in sub project have added reference project. after adding reference, able add using statement , have auto-complete pick right extension looking for. code wrote usual, when compiled, error the type of namespace name 'name1' not exist in namespace 'name2' (are missing assembly reference?) so have searched forums, have added several other system references , have gotten nothing. ran nuget update solution packages, , didn't make difference either. reason, when add reference (using add reference pop-up gui) reference name1 doesn't have dll file in it. if browse dll file directly, still gives me same issue when compiling. ideas appreciated. maybe can copy dll [projectname] / debug / or [projectname] / release /

hello want simple thing. make template function numbers. want little ability "add". in c++ trivial this: template <typename t> inline t add (t a, t b) { return + b; } int main(int argc, char** argv){ printf("int: %d\n",add(1,2)); printf("float: %f\n",add(1.1,2.1)); } in java got tough lesson. i'm new java believe (and hope) i'm totally wrong , on engineering this. thing come was: public interface intrfcwownumbersadds<t> { t add(number v); } public class supersmartinteger extends number implements intrfcwownumbersadds<supersmartinteger>{ private integer i; public supersmartinteger(int v) { = v; } @override public string tostring(){ return ""+i; } @override public supersmartinteger add(number v) { return new supersmartinteger(this.intvalue()+v.intvalue()); } @override public int intvalue() { return i; // thx god au

following material design, found cards . unfortunately can't found information dimensions of cards items of picture below. please tell me dimensions of cards need use. want know : what full height , full width of card item? what height of description area in card item(img_4130.jpg,img_4131.jpg,etc.) that's need. according docs in exact page linked, these not cards - represented android.support.v7.widget.cardview - tiles . you have implement own layout tiles , have dimensions wish, because pattern not standardized in docs. main differences between cards , tiles: cards have rounded corners. cards can have multiple actions. cards can dismissible , rearranged. while: tiles have square corners. tiles have no more 2 actions. so use tiles homogeneous content not-so-many actions in it. dimensions depend on images, basically.

this question has answer here: why javascript converts number values automatically 4 answers see snippet: var num = "9223372036854775808"; document.write(num); document.write("<br>"); document.write(parseint(num, 10)); on running code snippet, first write yields: 9223372036854775808 and third write yields: 9223372036854776000 but, parsing number in string form number. why give still larger number? i thought might have limits of storage capacity, then, why yield larger number if not store smaller? i read question: why parsing large number integer return 1 , parseint doc did not much. so, why parsing large number, of string form, return larger number? the first result fine treated string. in second one, crosses value of int +/- 9007199254740992 ie, maximum value parseint can parse 9007199254740992

i have datascience task requires getting historical weather data. have looked @ wunderground.com api example structured so: http://api.wunderground.com/api/d23ac65706dbf6dd/history_yyyymmdd/q/ca/san_francisco.json therefore, when attempting build dataset need first day of year last day of year, can't with: 20140101 20140102 20140103 ... 20141229 20141230 20141231 the thing can come is: for m in range(1, 13): d in range(1, 32): r = requests.get("http://api.wunderground.com/api/0def10027afaebb7/history_2014'+str(m)+'/'+str(d)+'/q/mexico/mexico_city.json") data = r.json() but won't work. how go in python? here minimal example demonstrates how iterate on actual dates: >>> import datetime >>> start = datetime.date(2014, 1, 1) >>> end = datetime.date(2014, 1, 5) >>> while start <= end: print start.strftime('%y%m%d') start += date

i'm implementing own math parser - , have few questions on how proceed. so far parser converting input string tokens: public class token { final public string expression; final public int value; public token(string expression, int value) { this.expression = expression; this.value = value; } } each string, expression, valid entry - number, operator or function. integer type passed enum identify token. when input string separated tokens expression parsed shunting-yard algorithm. my question : want tokens create objects of type. 1 way of doing might be: public abstract class mathcommand { final static hashtable<character, operator> operatortable = new hashtable<character, operator>() {{ put('+', new addition()); put('-', new subtraction()); put('/', new division()); put('*', new multiplication());

i have scenario in application need download mp3, pdf, text files using application. how can download, , store, data using application? nsstring *stringurl = @"http://www.somewhere.com/thefile.png"; nsurl *url = [nsurl urlwithstring:stringurl]; nsdata *urldata = [nsdata datawithcontentsofurl:url]; if ( urldata ) { nsarray*paths=nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes); nsstring *documentsdirectory = [paths objectatindex:0]; nsstring *filepath = [nsstring stringwithformat:@"%@/%@", documentsdirectory,@"filename.png"]; [urldata writetofile:filepath atomically:yes]; } you can store in document directory,below example store image .below link explained store audio video file how download audio/video files internet , store in iphone app?

i have student class. want overload + operator can add double variable class. here student class: class student { private: std::string firstname; double grade; public: student(const std::string &firstname, double grade); double getgrade() const; friend student operator+(double grade, const student &student); student operator+(double grade) const; }; and implementation: student::student(const std::string &firstname, double grade) { this->firstname = firstname; this->grade = grade; } double student::getgrade() const { return grade; } student operator+(double grade, const student &student) { return student(student.firstname, student.grade + grade); } student student::operator+(double grade) const { return operator+(grade, *this); } double + student done via friend function , student + double goes through member function. when compile this: error: no matching function call ‘student::operator+(double&

i'd programmatically handle javascript confirmation alert asking if you'd leave page (see screenshot below). the methods i've tried far have not worked. the browser not recognizing returning value true wanting leave page. this part trying handle alert: if @b.div(:class, "infomessagebox error").present? puts "there error" #@b.execute_script("window.confirm = function() {return true}") @b.execute_script("window.onbeforeunload = function() {};") @b.goto("#{@env}/translatefile.aspx") break end i have read article: " dismiss "confirm navigation" popup watir " method in article not in case. i apreciate because i'm stuck right here. this helped in solving problem. i improved code , works better here might other problems in future (hope not). @b.refresh if @b.alert.exists? @b.alert.text @b.alert.ok end @b.goto("#{@env}/translat
