mysql - Getting Next Closet Alarm Time In Android -


i trying implement following use case alarm application:

the user enters start date of alarm using date-picker. user can either select number of times he/she wants reminded per day 3 being maximum or user can select time intervals can reminded. in addition this, users can select days reminded at.

before setting alarm, save in database.

this how have designed database:

private final string alarms = "create table alarms(" +             "id integer primary key autoincrement" +             "date integer," +             "month integer," +             "year integer," +             "duration real," +             "continous int," +             "dow int," +             "timing int," +             "foreign key(timing) references alarmtiming (id)," +             "foreign key(dow) references alarmdow (id))";      private final string alarmdow = "create table alarmdow(" +             "id integer primary key autoincrement" +             "saturday integer," +             "sunday integer," +             "monday integer," +             "tuesday integer," +             "wednesday integer," +             "thursday integer," +             "friday integer)";      private final string alarmtiming = "create table alarmtiming(" +             "id integer primary key autoincrement" +             "interval integer," +             "hour1 integer," +             "minute1 integer," +             "hour2 integer," +             "minute2 integer," +             "hour3 integer," +             "minute3 integer)";

the alarms table takes alarm's start date (date,month,year) on table along options of if alarm continous or number of days duration.

alarmtiming table has hour value , minute value default -1. has interval calculating alarms shown in interval, example after every 6hrs or something.

the dow column stores corresponding days of week values references alarmdow table.

now working fine till , after doing research realized had make them separate tables. problem cant understand how make algorithm select closest alarm current time , use android's alarm manager set particular alarm , cycle continue values in tables.

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...
