javascript - Store every year directly from the date of entry of a user -


hi need store every year directly date of entry of user business problem every time add year inserted between day , month.

var yearoncompany = moment(user.fecha_ingreso_empresa, "yyyymmdd").fromnow(); var datestart = moment(user.fecha_ingreso_empresa).format("dd-mm-yyyy"); console.log(datestart); //03-12-2009 var f = parseint(yearoncompany); var yearsofwork = []; for(var = 1; <= f; i++) {     datestart = moment(datestart, "dd-mm-yyyy").add(1, 'years').calendar();     yearsofwork.push(datestart); } console.log(yearsofwork);

result of this:

0:"12/03/2010" 1:"03/12/2011" 2:"12/03/2012" 3:"03/12/2013" 4:"12/03/2014" 5:"03/12/2015" 6:"12/03/2016" 7:"03/12/2017"

this subtle error! according moment docs https://momentjs.com/docs/#/displaying/ .calendar() uses default date format, possibly using locale of environment, if none provided, here looks it's defaulting mm/dd/yyyy, rather desired dd/mm/yyyy. on first iteration datestart converted 12/03/2010 month , day swapped. on next iteration it's converted dd-mm-yyyy, again day , month swapped, when passed .calendar() again day , month swap again giving correct format again.

a potential bug you're changing datestart string moment object, i'd rewrite code this:

var datestart = moment(user.fecha_ingreso_empresa).format("dd-mm-yyyy"); var f = parseint(yearoncompany); var yearsofwork = []; for(var = 1; <= f; i++) {     datestart.add(1, 'years');     yearsofwork.push(datestart.format("dd-mm-yyyy")); } console.log(yearsofwork);

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
