java - Codename one SQLite data issue -


i working on codename 1 sqlite project, while getting issues, trying when clicking on specific date on calendar check whether date present in database or not, when firstly click on particular date after application starts gives accurate occurrence of date, @ second time add previous date occurrence present date occurrence , display summation of that. how can resolve it?

below code:-

public class customised extends calendar{          arraylist<string[]> data = new arraylist<>();             public customised(){      }      @override     protected void updatebuttondaydate(button daybutton, int currentmonth, int day) {              daybutton.settext(""+day);        daybutton.addactionlistener(new actionlistener() {            @override            public void actionperformed(actionevent evt) {                 try{         cur =  db.executequery("select date calendardata date = ? ", datelabel.gettext());          int columns = cur.getcolumncount();                       if(columns > 0) {                     boolean next = cur.next();                     if(next) {                          string[] columnnames = new string[columns];                         for(int iter = 0 ; iter < columns ; iter++) {                             columnnames[iter] = cur.getcolumnname(iter);                         }                         while(next) {                             row currentrow = cur.getrow();                             string[] currentrowarray = new string[columns];                             for(int iter = 0 ; iter < columns ; iter++) {                                 currentrowarray[iter] = currentrow.getstring(iter);                             }                             data.add(currentrowarray);                             next = cur.next();                         }                         object[][] arr = new object[data.size()][];                         data.toarray(arr);                     }                       }              }catch(ioexception e){                  e.printstacktrace();              }                int i;                for( = 0 ; i< data.size(); i++){                    log.p(data.get(i)[0]);                }                label = new label(datelabel.gettext());                label b = new label(""+i);                container container1 = tablelayout.enclosein(2, a,b);                calendar.add(container1);               util.cleanup(data);                // daybutton.getallstyles().setbgcolor(0xef5555);      //  daybutton.settext("* "+day);             }              });     }      @override     protected button createday() {        button day = new button();         day.setalignment(center);         day.setuiid("calendarday");         day.setendswith3points(false);         day.settickerenabled(false);         return day;     }     }  }

i got answer problem:- 

@override protected void updatebuttondaydate(button daybutton, int currentmonth, int day) {           daybutton.settext(""+day);    daybutton.addactionlistener(new actionlistener() {        @override        public void actionperformed(actionevent evt) {             try{     cur =  db.executequery("select date calendardata date = ? ", datelabel.gettext());      int columns = cur.getcolumncount();                   if(columns > 0) {                 boolean next = cur.next();                 if(next) {                      string[] columnnames = new string[columns];                     for(int iter = 0 ; iter < columns ; iter++) {                         columnnames[iter] = cur.getcolumnname(iter);                     }                     while(next) {                         row currentrow = cur.getrow();                         string[] currentrowarray = new string[columns];                         for(int iter = 0 ; iter < columns ; iter++) {                             currentrowarray[iter] = currentrow.getstring(iter);                         }                         data.add(currentrowarray);                         next = cur.next();                     }                     object[][] arr = new object[data.size()][];                     data.toarray(arr);                 }                   }          }catch(ioexception e){              e.printstacktrace();          }             for( = 0 ; i< data.size(); i++){                log.p(data.get(i)[0]);            }            label = new label(datelabel.gettext());            label b = new label(""+i);             container container1 = tablelayout.enclosein(2, a,b);            if(calendar.contains(container1)== true){                calendar.removecomponent(container1);            calendar.add(container1);            }else{                calendar.add(container1);            }            data.clear();            // daybutton.getallstyles().setbgcolor(0xef5555);  //  daybutton.settext("* "+day);         }          }); }

and response.

inversion of control - Autofac named registration constructor injection -

does autofac support specifying registration name in components' constructors? example: ninject's namedattribute . you need use autofac.extras.attributed package on top achieve this so let's have 1 interface , 2 classes: public interface ihello { string sayhello(); } public class englishhello : ihello { public string sayhello() { return "hello"; } } public class frenchhello : ihello { public string sayhello() { return "bonjour"; } } then have consumer class, in want select instance injected: public class helloconsumer { private readonly ihello helloservice; public helloconsumer([withkey("en")] ihello helloservice) { if (helloservice == null) { throw new argumentnullexception("helloservice"); } this.helloservice = helloservice; } public string sayhello() { return this.helloservice.sayhello()...

verilog - Systemverilog dynamic casting issues -

i've code snippet following in testbench function void write_to_port( my_data_type_base data ); my_data_type_extended data_ext; if(!$cast(data_ext, data)); `uvm_error(get_type_name(), "failed cast"); `uvm_info(get_name(), $psprintf("data_ext :\n%s", data_ext.sprint()), uvm_medium) // write data_ext out port.... endfunction when run it, i'm getting uvm_error "failed cast." i'm not quire sure why $cast not returning 1. can see, i'm printing out extended class data item after casting uvm_info. can see it's being cast properly. if don't use $cast if condition, don't runtime error. isn't coding practice use if dynamic cast check if $cast returning 1 ? what might reason behind cast not returning 1 in above case? i think semicolon on line 'if' not belong? i think consumes if statement, , uvm_error executes regardless of how if evaluates: if(!$cast(data_ext, data)); <- no semico...
