In Java8 you can use get ValueRange from a field of a date.

LocalDateTime dateTime = LocalDateTime.now();

ChronoField chronoField = ChronoField.MONTH_OF_YEAR;
long max = dateTime.range(chronoField).getMaximum();

This allows you to parameterize on the field.

Replace this:

c1.set(Calendar.HOUR, d1.getHours());

with this:

c1.set(Calendar.HOUR_OF_DAY, d1.getHours());

Calendar.HOUR is strictly for 12 hours.

Here's an Add to Calendar service to serve the purpose for adding an event on

1. Apple Calendar
2. Google Calendar
3. Outlook
4. Outlook Online
5. Yahoo! Calendar

The "Add to Calendar" button for events on websites and calendars is easy to install, language independent, time zone and DST compatible. It works perfectly in all modern browsers, tablets and mobile devices, and with Apple Calendar, Google Calendar, Outlook, Outlook.com and Yahoo Calendar.

<div title="Add to Calendar" class="addeventatc">
    Add to Calendar
    <span class="start">03/01/2018 08:00 AM</span>
    <span class="end">03/01/2018 10:00 AM</span>
    <span class="timezone">America/Los_Angeles</span>
    <span class="title">Summary of the event</span>
    <span class="description">Description of the event</span>
    <span class="location">Location of the event</span>
</div>

Selected date at the example is interesting. Example code block is:

Calendar c1 = GregorianCalendar.getInstance();
c1.set(2000, 1, 30);  //January 30th 2000
Date sDate = c1.getTime();

System.out.println(sDate);

and output Wed Mar 01 19:32:21 JST 2000.

When I first read the example i think that output is wrong but it is true:)

• Calendar.Month is starting from 0 so 1 means February.
• February last day is 28 so output should be 2 March.
• But selected year is important, it is 2000 which means February 29 so result should be 1 March.

Simple.... use tapku library.... you can google that word and use it... its open source... enjoy..... no need of bugging with those codes....

java.time

The answer by MadProgrammer is correct, especially the tip about Joda-Time. The successor to Joda-Time is now built into Java 8 as the new java.time package. Here's example code in Java 8.

When working with date-time (as opposed to local date), the time zone in critical. The day-of-month depends on the time zone. For example, the India time zone is +05:30 (five and a half hours ahead of UTC), while France is only one hour ahead. So a moment in a new day in India has one date while the same moment in France has “yesterday’s” date. Creating string output lacking any time zone or offset information is creating ambiguity. You asked for YYYY-MM-DD output so I provided, but I don't recommend it. Instead of ISO_LOCAL_DATE I would have used ISO_DATE to get this output: 2014-02-25+05:30

ZoneId zoneId = ZoneId.of( "Asia/Kolkata" );
ZonedDateTime zonedDateTime = ZonedDateTime.now( zoneId );

DateTimeFormatter formatterOutput = DateTimeFormatter.ISO_LOCAL_DATE; // Caution: The "LOCAL" part means we are losing time zone information, creating ambiguity.
String output = formatterOutput.format( zonedDateTime );

Dump to console…

System.out.println( "zonedDateTime: " + zonedDateTime );
System.out.println( "output: " + output );

When run…

zonedDateTime: 2014-02-25T14:22:20.919+05:30[Asia/Kolkata]
output: 2014-02-25

Joda-Time

Similar code using the Joda-Time library, the precursor to java.time.

DateTimeZone zone = new DateTimeZone( "Asia/Kolkata" );
DateTime dateTime = DateTime.now( zone );
DateTimeFormatter formatter = ISODateTimeFormat.date();
String output = formatter.print( dateTime );

ISO 8601

By the way, that format of your input string is a standard format, one of several handy date-time string formats defined by ISO 8601.

Both Joda-Time and java.time use ISO 8601 formats by default when parsing and generating string representations of various date-time values.

I should like to contribute the modern answer. This involves using java.time, the modern Java date and time API, and not the old Date nor Calendar except where there’s no way to avoid it.

Your issue is very likely really a timezone issue. When it is Tue Aug 09 00:00:00 IST 2011, in time zones west of IST midnight has not yet been reached. It is still Aug 8. If for example your API for putting the date into Excel expects UTC, the date will be the day before the one you intended. I believe the real and good solution is to produce a date-time of 00:00 UTC (or whatever time zone or offset is expected and used at the other end).

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    ZonedDateTime utcDateDime = yourDate.atStartOfDay(ZoneOffset.UTC);
    System.out.println(utcDateDime);

This prints

2018-02-27T00:00Z

Z means UTC (think of it as offset zero from UTC or Zulu time zone). Better still, of course, if you could pass the LocalDate from the first code line to Excel. It doesn’t include time-of-day, so there is no confusion possible. On the other hand, if you need an old-fashioned Date object for that, convert just before handing the Date on:

    Date oldfashionedDate = Date.from(utcDateDime.toInstant());
    System.out.println(oldfashionedDate);

On my computer this prints

Tue Feb 27 01:00:00 CET 2018

Don’t be fooled, it is correct. My time zone (Central European Time) is at offset +01:00 from UTC in February (standard time), so 01:00:00 here is equal to 00:00:00 UTC. It’s just Date.toString() grabbing the JVMs time zone and using it for producing the string.

How can I set it to something like 5:30 pm?

To answer your direct question directly, if you have a ZonedDateTime, OffsetDateTime or LocalDateTime, in all of these cases the following will accomplish what you asked for:

    yourDateTime = yourDateTime.with(LocalTime.of(17, 30));

If yourDateTime was a LocalDateTime of 2018-02-27T00:00, it will now be 2018-02-27T17:30. Similarly for the other types, only they include offset and time zone too as appropriate.

If you only had a date, as in the first snippet above, you can also add time-of-day information to it:

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    LocalDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30));

For most purposes you should prefer to add the time-of-day in a specific time zone, though, for example

    ZonedDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30))
            .atZone(ZoneId.of("Asia/Kolkata"));

This yields 2018-02-27T17:30+05:30[Asia/Kolkata].

Date and Calendar vs java.time

The Date class that you use as well as Calendar and SimpleDateFormat used in the other answers are long outdated, and SimpleDateFormat in particular has proven troublesome. In all cases the modern Java date and time API is so much nicer to work with. Which is why I wanted to provide this answer to an old question that is still being visited.

Link: Oracle Tutorial Date Time, explaining how to use java.time.

Anson's answer will work fine for the simple case, but if you're going to do any more complex date calculations I'd recommend checking out Joda Time. It will make your life much easier.

FYI in Joda Time you could do

DateTime dt = new DateTime();
DateTime fiveDaysEarlier = dt.minusDays(5);

In Java 8 you can use:

LocalDate date = LocalDate.now(); //2020-01-12
date.withDayOfMonth(1); //2020-01-01

It's

DateTime.Now.ToString("MMMM");

With 4 Ms.

Here's your method:

public static Calendar toCalendar(Date date){ 
  Calendar cal = Calendar.getInstance();
  cal.setTime(date);
  return cal;
}

Everything else you are doing is both wrong and unnecessary.

BTW, Java Naming conventions suggest that method names start with a lower case letter, so it should be: dateToCalendar or toCalendar (as shown).

OK, let's milk your code, shall we?

DateFormat formatter = new SimpleDateFormat("yyyyMMdd");
date = (Date)formatter.parse(date.toString()); 

DateFormat is used to convert Strings to Dates (parse()) or Dates to Strings (format()). You are using it to parse the String representation of a Date back to a Date. This can't be right, can it?

Much simpler using only SimpleDateFormat, without passing all the parameters individual:

    String FORMATER = "yyyy-MM-dd'T'HH:mm:ss'Z'";

    DateFormat format = new SimpleDateFormat(FORMATER);

    Date date = new Date();
    XMLGregorianCalendar gDateFormatted =
        DatatypeFactory.newInstance().newXMLGregorianCalendar(format.format(date));

Full example here.

Note: This is working only to remove the last 2 fields: milliseconds and timezone or to remove the entire time component using formatter yyyy-MM-dd.

tl;dr

Instant stop = 
    myUtilDateStart.toInstant()
                   .plus( Duration.ofMinutes( x ) ) 
;

java.time

Other Answers are correct, especially the Answer by Borgwardt. But those Answers use outmoded legacy classes.

The original date-time classes bundled with Java have been supplanted with java.time classes. Perform your business logic in java.time types. Convert to the old types only where needed to work with old code not yet updated to handle java.time types.

If your Calendar is actually a GregorianCalendar you can convert to a ZonedDateTime. Find new methods added to the old classes to facilitate conversion to/from java.time types.

if( myUtilCalendar instanceof GregorianCalendar ) {
    GregorianCalendar gregCal = (GregorianCalendar) myUtilCalendar; // Downcasting from the interface to the concrete class.
    ZonedDateTime zdt = gregCal.toZonedDateTime();  // Create `ZonedDateTime` with same time zone info found in the `GregorianCalendar`
end if 

If your Calendar is not a Gregorian, call toInstant to get an Instant object. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = myCal.toInstant();

Similarly, if starting with a java.util.Date object, convert to an Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myUtilDate.toInstant();

Apply a time zone to get a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = instant.atZone( z );

To get a java.util.Date object, go through the Instant.

java.util.Date utilDate = java.util.Date.from( zdt.toInstant() );

For more discussion of converting between the legacy date-time types and java.time, and a nifty diagram, see my Answer to another Question.

Duration

Represent the span of time as a Duration object. Your input for the duration is a number of minutes as mentioned in the Question.

Duration d = Duration.ofMinutes( yourMinutesGoHere );

You can add that to the start to determine the stop.

Instant stop = startInstant.plus( d ); 

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Calender cal = Calendar.getInstance(Locale.ENGLISH)
String[] mons = new DateFormatSymbols(Locale.ENGLISH).getShortMonths();
int m = cal.get(Calendar.MONTH);
String mName = mons[m];

Date mDate = new Date(System.currentTimeMillis());
mDate.getMonth() + 1

The returned value starts from 0, so you should add one to the result.

var mydate = "2017-06-28T00:00:00";
var weekDayName =  moment(mydate).format('ddd');
console.log(weekDayName);

Result: Wed

var mydate = "2017-06-28T00:00:00";
var weekDayName =  moment(mydate).format('dddd');
console.log(weekDayName);

Result: Wednesday

You can use SimpleDateFormat

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
Date d = sdf.parse("21/12/2012");

But I don't know whether it should be considered more right than to use Calendar ...

Make your life easy when working with dates, timestamps and durations. Use HalDateTime from

http://sourceforge.net/projects/haldatetime/?source=directory

For example you can just use it to parse your input like this:

HalDateTime mydate = HalDateTime.valueOf( "25.12.1988" );
System.out.println( mydate );   // will print in ISO format: 1988-12-25

You can also specify patterns for parsing and printing.

This is the problem to start with:

Calendar cal = Calendar.getInstance(TimeZone.getTimeZone("EST"));

The 3-letter abbreviations should be wholeheartedly avoided in favour of TZDB zone IDs. EST is Eastern Standard Time - and Standard time never observes DST; it's not really a full time zone name. It's the name used for part of a time zone. (Unfortunately I haven't come across a good term for this "half time zone" concept.)

You want a full time zone name. For example, America/New_York is in the Eastern time zone:

TimeZone zone = TimeZone.getTimeZone("America/New_York");
DateFormat format = DateFormat.getDateTimeInstance();
format.setTimeZone(zone);

System.out.println(format.format(new Date()));

Here's the code snippet.I think it works.

      Calendar cal = Calendar.getInstance();
      SimpleDateFormat simpleMonth=new SimpleDateFormat("MMMM YYYY");
      cal.add(Calendar.MONTH, -1);
      System.out.println(simpleMonth.format(prevcal.getTime()));

Just need to define yy-mm-dd here. dateFormat

Default is mm-dd-yy

Change mm-dd-yy to yy-mm-dd. Look example below

  $(function() {
    $( "#datepicker" ).datepicker({
      dateFormat: 'yy-mm-dd',
      changeMonth: true,
      changeYear: true
    });
  } );

Date: <input type="text" id="datepicker">

Depending on your application, you may want to consider using System.nanoTime() instead.

Here is a simple implementation of the wikipedia algorithm, using the javascript ternary operator:

isLeapYear = (year % 100 === 0) ? (year % 400 === 0) : (year % 4 === 0);

There is also this tool you can use. It supports multi-events .ics file creation. It also supports timezone as well.

http://apps.marudot.com/ical/

As shown by @Maglob, the basic approach is to test the conversion from string to date using SimpleDateFormat.parse. That will catch invalid day/month combinations like 2008-02-31.

However, in practice that is rarely enough since SimpleDateFormat.parse is exceedingly liberal. There are two behaviours you might be concerned with:

Invalid characters in the date string Surprisingly, 2008-02-2x will "pass" as a valid date with locale format = "yyyy-MM-dd" for example. Even when isLenient==false.

Years: 2, 3 or 4 digits? You may also want to enforce 4-digit years rather than allowing the default SimpleDateFormat behaviour (which will interpret "12-02-31" differently depending on whether your format was "yyyy-MM-dd" or "yy-MM-dd")

A Strict Solution with the Standard Library

So a complete string to date test could look like this: a combination of regex match, and then a forced date conversion. The trick with the regex is to make it locale-friendly.

  Date parseDate(String maybeDate, String format, boolean lenient) {
    Date date = null;

    // test date string matches format structure using regex
    // - weed out illegal characters and enforce 4-digit year
    // - create the regex based on the local format string
    String reFormat = Pattern.compile("d+|M+").matcher(Matcher.quoteReplacement(format)).replaceAll("\\\\d{1,2}");
    reFormat = Pattern.compile("y+").matcher(reFormat).replaceAll("\\\\d{4}");
    if ( Pattern.compile(reFormat).matcher(maybeDate).matches() ) {

      // date string matches format structure, 
      // - now test it can be converted to a valid date
      SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance();
      sdf.applyPattern(format);
      sdf.setLenient(lenient);
      try { date = sdf.parse(maybeDate); } catch (ParseException e) { }
    } 
    return date;
  } 

  // used like this:
  Date date = parseDate( "21/5/2009", "d/M/yyyy", false);

Note that the regex assumes the format string contains only day, month, year, and separator characters. Aside from that, format can be in any locale format: "d/MM/yy", "yyyy-MM-dd", and so on. The format string for the current locale could be obtained like this:

Locale locale = Locale.getDefault();
SimpleDateFormat sdf = (SimpleDateFormat)DateFormat.getDateInstance(DateFormat.SHORT, locale );
String format = sdf.toPattern();

Joda Time - Better Alternative?

I've been hearing about joda time recently and thought I'd compare. Two points:

1. Seems better at being strict about invalid characters in the date string, unlike SimpleDateFormat
2. Can't see a way to enforce 4-digit years with it yet (but I guess you could create your own DateTimeFormatter for this purpose)

It's quite simple to use:

import org.joda.time.format.*;
import org.joda.time.DateTime;

org.joda.time.DateTime parseDate(String maybeDate, String format) {
  org.joda.time.DateTime date = null;
  try {
    DateTimeFormatter fmt = DateTimeFormat.forPattern(format);
    date =  fmt.parseDateTime(maybeDate);
  } catch (Exception e) { }
  return date;
}

The best way for new code (if your policy allows third-party code) is to use the Joda Time library.

Both, Date and Calendar, have so many design problems that neither are good solutions for new code.

Use the constructor Date(year,month,date) in Java 8 it is deprecated:

Date date = new Date(1990, 10, 26, 0, 0);

The best way is to use SimpleDateFormat

DateFormat format = new SimpleDateFormat("dd/MM/yyyy");
Date date = format.parse("26/10/1985");

you need to import import java.text.SimpleDateFormat;

In Java, Dates are internally represented in UTC milliseconds since the epoch (so timezones are not taken into account, that's why you get the same results, as getTime() gives you the mentioned milliseconds).
In your solution:

Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
long gmtTime = cSchedStartCal.getTime().getTime();

long timezoneAlteredTime = gmtTime + TimeZone.getTimeZone("Asia/Calcutta").getRawOffset();
Calendar cSchedStartCal1 = Calendar.getInstance(TimeZone.getTimeZone("Asia/Calcutta"));
cSchedStartCal1.setTimeInMillis(timezoneAlteredTime);

you just add the offset from GMT to the specified timezone ("Asia/Calcutta" in your example) in milliseconds, so this should work fine.

Another possible solution would be to utilise the static fields of the Calendar class:

//instantiates a calendar using the current time in the specified timezone
Calendar cSchedStartCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
//change the timezone
cSchedStartCal.setTimeZone(TimeZone.getTimeZone("Asia/Calcutta"));
//get the current hour of the day in the new timezone
cSchedStartCal.get(Calendar.HOUR_OF_DAY);

Refer to stackoverflow.com/questions/7695859/ for a more in-depth explanation.

In brief:

DateFormat formatter = new SimpleDateFormat("MM/dd/yy");
try {
  Date date = formatter.parse("01/29/02");
} catch (ParseException e) {
  e.printStackTrace();
}

See SimpleDateFormat javadoc for more.

And to turn it into a Calendar, do:

Calendar calendar = Calendar.getInstance();
calendar.setTime(date);

http://www.kanzaki.com/docs/ical/ has a slightly more readable version of the older spec. It helps as a starting point - many things are still the same.

Also on my site, I have

1. Some lists of useful resources (see sidebar bottom right) on
   • ical Spec RFC 5545
   • ical Testing Resources
2. Some notes recorded on my journey working with .ics over the last few years. In particular, you may find this repeating events 'cheatsheet' to be useful.

.ics areas that need careful handling:

• 'all day' events
• types of dates (timezone, UTC, or local 'floating') - nb to understand distinction
• interoperability of recurrence rules

Calendar.get takes as argument one of the standard Calendar fields, like YEAR or MONTH not a month name.

Calendar.JANUARY is 0, which is also the value of Calendar.ERA, so Calendar.getInstance().get(0) will return the era, in this case Calendar.AD, which is 1.

For the first part of your question, note that, as is wildly documented, months start at 0, so 10 is actually November.

@Rogue Coder

This is great!

You could simply use the modulo operation (MOD or % in mysql) to make your code simple at the end:

Instead of:

AND (
    ( CASE ( 1299132000 - EM1.`meta_value` )
        WHEN 0
          THEN 1
        ELSE ( 1299132000 - EM1.`meta_value` )
      END
    ) / EM2.`meta_value`
) = 1

Do:

$current_timestamp = 1299132000 ;

AND ( ('$current_timestamp' - EM1.`meta_value` ) MOD EM2.`meta_value`) = 1")

To take this further, one could include events that do not recur for ever.

Something like "repeat_interval_1_end" to denote the date of the last "repeat_interval_1" could be added. This however, makes the query more complicated and I can't really figure out how to do this ...

Maybe someone could help!

I too had the same problem in VWD 2010 and, by chance, I had two controls. One was available in code behind and one wasn't accessible. I thought that the order of statements in the controls was causing the issue. I put 'runat' before 'SelectedDate' and that seemed to fix it. When I put 'runat' after 'SelectedDate' it still worked! Unfortunately, I now don't know why it didn't work and haven't got the original that didn't work.

These now all work:-

<asp:Calendar ID="calDateFrom" SelectedDate="08/02/2011" SelectionMode="Day" runat="server"></asp:Calendar>
<asp:Calendar runat="server" SelectionMode="Day" SelectedDate="08/15/2011 12:00:00 AM" ID="Calendar1" VisibleDate="08/03/2011 12:00:00 AM"></asp:Calendar>
<asp:Calendar SelectionMode="Day" SelectedDate="08/31/2011 12:00:00 AM" runat="server" ID="calDateTo"></asp:Calendar>

Use GregorianCalendar. Set the date of the object, and then use getActualMaximum(Calendar.DAY_IN_MONTH).

http://docs.oracle.com/javase/7/docs/api/java/util/GregorianCalendar.html#getActualMaximum%28int%29 (but it was the same in Java 1.4)

As you can see HERE there is a lot of manipulation you can do. Here an example showing what you could do!

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();

//Add one day to current date.
cal.add(Calendar.DATE, 1);
System.out.println(dateFormat.format(cal.getTime()));

//Substract one day to current date.
cal = Calendar.getInstance();
cal.add(Calendar.DATE, -1);
System.out.println(dateFormat.format(cal.getTime()));

/* Can be Calendar.DATE or
*  Calendar.MONTH, Calendar.YEAR, Calendar.HOUR, Calendar.SECOND
*/

use this format,

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");

mm for minutes and MM for mounth

The string $.datepicker.regional['it'] not translate all words.

For translate the datepicker you must specify some variables:

$.datepicker.regional['it'] = {
    closeText: 'Chiudi', // set a close button text
    currentText: 'Oggi', // set today text
    monthNames: ['Gennaio','Febbraio','Marzo','Aprile','Maggio','Giugno',   'Luglio','Agosto','Settembre','Ottobre','Novembre','Dicembre'], // set month names
    monthNamesShort: ['Gen','Feb','Mar','Apr','Mag','Giu','Lug','Ago','Set','Ott','Nov','Dic'], // set short month names
    dayNames: ['Domenica','Luned&#236','Marted&#236','Mercoled&#236','Gioved&#236','Venerd&#236','Sabato'], // set days names
    dayNamesShort: ['Dom','Lun','Mar','Mer','Gio','Ven','Sab'], // set short day names
    dayNamesMin: ['Do','Lu','Ma','Me','Gio','Ve','Sa'], // set more short days names
    dateFormat: 'dd/mm/yy' // set format date
};

$.datepicker.setDefaults($.datepicker.regional['it']);

$(".datepicker").datepicker();

In this case your datepicker is properly translated.

Just in case if someone needs this for Xamarin in c#:

        Intent intent = new Intent(Intent.ActionInsert);
        intent.SetData(Android.Provider.CalendarContract.Events.ContentUri);
        intent.PutExtra(Android.Provider.CalendarContract.ExtraEventBeginTime, Utils.Tools.CurrentTimeMillis(game.Date));
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.AllDay, false);
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.EventLocation, "Location");
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.Description, "Description");
        intent.PutExtra(Android.Provider.CalendarContract.ExtraEventEndTime, Utils.Tools.CurrentTimeMillis(game.Date.AddHours(2)));
        intent.PutExtra(Android.Provider.CalendarContract.EventsColumns.Title, "Title");
        StartActivity(intent);

Helper Functions:

    private static readonly DateTime Jan1st1970 = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

    public static long CurrentTimeMillis(DateTime date)
    {
        return (long)(date.ToUniversalTime() - Jan1st1970).TotalMilliseconds;
    }

Nope, it is more complicated than just calling a method, if you want to transparently add it into the user's calendar.

You've got a couple of choices;

1. Calling the intent to add an event on the calendar
   This will pop up the Calendar application and let the user add the event. You can pass some parameters to prepopulate fields:

   Calendar cal = Calendar.getInstance();              
   Intent intent = new Intent(Intent.ACTION_EDIT);
   intent.setType("vnd.android.cursor.item/event");
   intent.putExtra("beginTime", cal.getTimeInMillis());
   intent.putExtra("allDay", false);
   intent.putExtra("rrule", "FREQ=DAILY");
   intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
   intent.putExtra("title", "A Test Event from android app");
   startActivity(intent);
   

   Or the more complicated one:

2. Get a reference to the calendar with this method
   (It is highly recommended not to use this method, because it could break on newer Android versions):

   private String getCalendarUriBase(Activity act) {
   
       String calendarUriBase = null;
       Uri calendars = Uri.parse("content://calendar/calendars");
       Cursor managedCursor = null;
       try {
           managedCursor = act.managedQuery(calendars, null, null, null, null);
       } catch (Exception e) {
       }
       if (managedCursor != null) {
           calendarUriBase = "content://calendar/";
       } else {
           calendars = Uri.parse("content://com.android.calendar/calendars");
           try {
               managedCursor = act.managedQuery(calendars, null, null, null, null);
           } catch (Exception e) {
           }
           if (managedCursor != null) {
               calendarUriBase = "content://com.android.calendar/";
           }
       }
       return calendarUriBase;
   }
   

   and add an event and a reminder this way:

   // get calendar
   Calendar cal = Calendar.getInstance();     
   Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
   ContentResolver cr = getContentResolver();
   
   // event insert
   ContentValues values = new ContentValues();
   values.put("calendar_id", 1);
   values.put("title", "Reminder Title");
   values.put("allDay", 0);
   values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
   values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
   values.put("description", "Reminder description");
   values.put("visibility", 0);
   values.put("hasAlarm", 1);
   Uri event = cr.insert(EVENTS_URI, values);
   
   // reminder insert
   Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
   values = new ContentValues();
   values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
   values.put( "method", 1 );
   values.put( "minutes", 10 );
   cr.insert( REMINDERS_URI, values );
   

   You'll also need to add these permissions to your manifest for this method:

   <uses-permission android:name="android.permission.READ_CALENDAR" />
   <uses-permission android:name="android.permission.WRITE_CALENDAR" />
   

Update: ICS Issues

The above examples use the undocumented Calendar APIs, new public Calendar APIs have been released for ICS, so for this reason, to target new android versions you should use CalendarContract.

Here is the java code to calculate age in year, month and days.

public static AgeModel calculateAge(long birthDate) {
    int years = 0;
    int months = 0;
    int days = 0;

    if (birthDate != 0) {
        //create calendar object for birth day
        Calendar birthDay = Calendar.getInstance();
        birthDay.setTimeInMillis(birthDate);

        //create calendar object for current day
        Calendar now = Calendar.getInstance();
        Calendar current = Calendar.getInstance();
        //Get difference between years
        years = now.get(Calendar.YEAR) - birthDay.get(Calendar.YEAR);

        //get months
        int currMonth = now.get(Calendar.MONTH) + 1;
        int birthMonth = birthDay.get(Calendar.MONTH) + 1;

        //Get difference between months
        months = currMonth - birthMonth;

        //if month difference is in negative then reduce years by one and calculate the number of months.
        if (months < 0) {
            years--;
            months = 12 - birthMonth + currMonth;
        } else if (months == 0 && now.get(Calendar.DATE) < birthDay.get(Calendar.DATE)) {
            years--;
            months = 11;
        }

        //Calculate the days
        if (now.get(Calendar.DATE) > birthDay.get(Calendar.DATE))
            days = now.get(Calendar.DATE) - birthDay.get(Calendar.DATE);
        else if (now.get(Calendar.DATE) < birthDay.get(Calendar.DATE)) {
            int today = now.get(Calendar.DAY_OF_MONTH);
            now.add(Calendar.MONTH, -1);
            days = now.getActualMaximum(Calendar.DAY_OF_MONTH) - birthDay.get(Calendar.DAY_OF_MONTH) + today;
        } else {
            days = 0;
            if (months == 12) {
                years++;
                months = 0;
            }
        }
    }

    //Create new Age object
    return new AgeModel(days, months, years);
}

Probably because C's "struct tm" does the same.

In your case the starting time (20:11:13) is larger than the ending time (14:49:00). It is a reasonable assumption that you could solve the problem by adding a day on the ending time or subtracting a day from the starting time. if you do so, you will be trapped because you do not know on which day the testing time is.

You can avoid this trap by checking whether your testing time is between the ending time and starting time. If true, then result is "not in between"; else result is "well in between".

Here is the function in JAVA I have been using. It works so far for me. Good luck.

boolean IsTimeInBetween(Calendar startC, Calendar endC, Calendar testC){
    // assume year, month and day of month are all equal.
    startC.set(1,1,1);
    endC.set(1,1,1);
    testC.set(1,1,1);

    if (endC.compareTo(startC) > 0) {
        if ((testC.compareTo(startC)>=0) && (testC.compareTo(endC)<=0)) {
            return true;
        }else {
            return false;
        }
    }else if  (endC.compareTo(startC) < 0) {
        if ((testC.compareTo(endC) >= 0) && (testC.compareTo(startC) <= 0)) {
            return false;
        } else {
            return true;
        }
    } else{ // when endC.compareTo(startC)==0, I return a ture value. Change it if you have different application. 
        return true;
    }
}

To create a Calender instance you can use:

Calendar startC = Calendar.getInstance();
startC.set(Calendar.HOUR_OF_DAY, 20);
startC.set(Calendar.MINUTE,11);
startC.set(Calendar.SECOND,13);

Use this :

Calendar cal=Calendar.getInstance();
SimpleDateFormat month_date = new SimpleDateFormat("MMMM");
String month_name = month_date.format(cal.getTime());

Month name will contain the full month name,,if you want short month name use this

 SimpleDateFormat month_date = new SimpleDateFormat("MMM");
 String month_name = month_date.format(cal.getTime());

This one will give you date no time:

=FormatDateTime(DateAdd("m", -1, DateSerial(Year(Today()), Month(Today()), 1)), 
DateFormat.ShortDate)

This one will give you datetime:

=dateadd("m",-1,dateserial(year(Today),month(Today),1)) 

I found this code works:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy MMM dd HH:mm:ss");    
Calendar calendar = new GregorianCalendar(2013,0,31);
System.out.println(sdf.format(calendar.getTime()));

In case you already use jquery-ui (specifically datepicker):

Date.prototype.getWeek = function () { return $.datepicker.iso8601Week(this); }

Usage:

var myDate = new Date();
myDate.getWeek();

More here: UI/Datepicker/iso8601Week

I realize this isn't a general solution as it incurs a dependency. However, considering the popularity of jquery-ui this might just be a simple fit for someone - as it was for me.

If you need to get how much time was between two dates you can use https://github.com/maximnara/business-days-counter. It's works simply but only with laravel now $diffInSeconds = $this->datesCounter->getDifferenceInSeconds(Carbon::create(2019, 1, 1), Carbon::now(), DateCounter::COUNTRY_FR);

It doesn't counts public holidays and weekends and you can set working interval, for example from 9 to 18 with launch hour or no.

Or if you need just weekends and you use Carbon you can use built in function:

$date1 = Carbon::create(2019, 1, 1)->endOfDay();
$date2 = $dt->copy()->startOfDay();
$diff = $date1->diffFiltered(CarbonInterval::minute(), function(Carbon $date) {
   return !$date->isWeekend();
}, $date2, true);

But it will foreach every minute in interval, for bit intervals it can take a while.

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

tl;dr

The modern approach uses the java.time classes.

YearMonth.from(

Avoid legacy date-time classes

The modern way is with java.time classes. The old date-time classes such as Calendar have proven to be poorly-designed, confusing, and troublesome.

Define a custom formatter to match your string input.

String input = "Mon Mar 14 16:02:37 GMT 2011";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" );

Parse as a ZonedDateTime.

ZonedDateTime zdt = ZonedDateTime.parse( input , f );

You are interested in the year and month. The java.time classes include YearMonth class for that purpose.

YearMonth ym = YearMonth.from( zdt );

You can interrogate for the year and month numbers if needed.

int year = ym.getYear();
int month = ym.getMonthValue();

But the toString method generates a string in standard ISO 8601 format.

String output = ym.toString();

Put this all together.

String input = "Mon Mar 14 16:02:37 GMT 2011";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM d HH:mm:ss z uuuu" );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );
YearMonth ym = YearMonth.from( zdt );
int year = ym.getYear();
int month = ym.getMonthValue();

Dump to console.

System.out.println( "input: " + input );
System.out.println( "zdt: " + zdt );
System.out.println( "ym: " + ym );

input: Mon Mar 14 16:02:37 GMT 2011

zdt: 2011-03-14T16:02:37Z[GMT]

ym: 2011-03

Conversion

If you must have a Calendar object, you can convert to a GregorianCalendar using new methods added to the old classes.

GregorianCalendar gc = GregorianCalendar.from( zdt );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Thank you all for responding. After a further investigation I got to the right answer. As mentioned by Skip Head, the TimeStamped I was getting from my application was being adjusted to the user's TimeZone. So if the User entered 6:12 PM (EST) I would get 2:12 PM (GMT). What I needed was a way to undo the conversion so that the time entered by the user is the time I sent to the WebServer request. Here's how I accomplished this:

// Get TimeZone of user
TimeZone currentTimeZone = sc_.getTimeZone();
Calendar currentDt = new GregorianCalendar(currentTimeZone, EN_US_LOCALE);
// Get the Offset from GMT taking DST into account
int gmtOffset = currentTimeZone.getOffset(
    currentDt.get(Calendar.ERA), 
    currentDt.get(Calendar.YEAR), 
    currentDt.get(Calendar.MONTH), 
    currentDt.get(Calendar.DAY_OF_MONTH), 
    currentDt.get(Calendar.DAY_OF_WEEK), 
    currentDt.get(Calendar.MILLISECOND));
// convert to hours
gmtOffset = gmtOffset / (60*60*1000);
System.out.println("Current User's TimeZone: " + currentTimeZone.getID());
System.out.println("Current Offset from GMT (in hrs):" + gmtOffset);
// Get TS from User Input
Timestamp issuedDate = (Timestamp) getACPValue(inputs_, "issuedDate");
System.out.println("TS from ACP: " + issuedDate);
// Set TS into Calendar
Calendar issueDate = convertTimestampToJavaCalendar(issuedDate);
// Adjust for GMT (note the offset negation)
issueDate.add(Calendar.HOUR_OF_DAY, -gmtOffset);
System.out.println("Calendar Date converted from TS using GMT and US_EN Locale: "
    + DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT)
    .format(issueDate.getTime()));

The code's output is: (User entered 5/1/2008 6:12PM (EST)

Current User's TimeZone: EST
Current Offset from GMT (in hrs):-4 (Normally -5, except is DST adjusted)
TS from ACP: 2008-05-01 14:12:00.0
Calendar Date converted from TS using GMT and US_EN Locale: 5/1/08 6:12 PM (GMT)

By definition, the first two numbers in the Fibonacci sequence are 1 and 1, or 0 and 1. Therefore, you should handle it.

#include <iostream>
using namespace std;

int Fibonacci(int);

int main(void) {
    int number;

    cout << "Please enter a positive integer: ";
    cin >> number;
    if (number < 0)
        cout << "That is not a positive integer.\n";
    else
        cout << number << " Fibonacci is: " << Fibonacci(number) << endl;
}

int Fibonacci(int x) 
{
    if (x < 2){
     return x;
    }     
    return (Fibonacci (x - 1) + Fibonacci (x - 2));
}

You can probably add two foreign key constraints (honestly: I've never tried it), but it'd then insist the parent row exist in both tables.

Instead you probably want to create a supertype for your two employee subtypes, and then point the foreign key there instead. (Assuming you have a good reason to split the two types of employees, of course).

                 employee       
employees_ce     ————————       employees_sn
————————————     type           ————————————
empid —————————> empid <——————— empid
name               /|\          name
                    |  
                    |  
      deductions    |  
      ——————————    |  
      empid ————————+  
      name

type in the employee table would be ce or sn.

To solve this problem, also check if you have some included .js into your ajax file called: I received Access denied error while including shadowbox.js in my ajax.php

The name is present inside the data. You need to parse a JSON hierarchically to be able to fetch the data properly.

JSONObject jObject  = new JSONObject(output); // json
JSONObject data = jObject.getJSONObject("data"); // get data object
String projectname = data.getString("name"); // get the name from data.

Note: This example uses the org.json.JSONObject class and not org.json.simple.JSONObject.

As "Matthew" mentioned in the comments that he is using org.json.simple.JSONObject, I'm adding my comment details in the answer.

Try to use the org.json.JSONObject instead. But then if you can't change your JSON library, you can refer to this example which uses the same library as yours and check the how to read a json part from it.

Sample from the link provided:

JSONObject jsonObject = (JSONObject) obj;
String name = (String) jsonObject.get("name");

Many solutions have been provided, but I have not seen this one, which uses package chron:

hours = times(strftime(times, format="%T"))
plot(val~hours)

(sorry, I am not entitled to post an image, you'll have to plot it yourself)

Actually, there are many issues with different environments, python versions, so on. You might also need to install python dev files, so to 'brute-force' the installation I would run all of these:

sudo apt-get install python-dev python3-dev
sudo apt-get install libmysqlclient-dev
pip install MySQL-python
pip install pymysql
pip install mysqlclient

You should be good to go with the accepted answer. And can remove the unnecessary packages if that's important to you.

Use datetime.datetime.fromtimestamp:

>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'

%f directive is only supported by datetime.datetime.strftime, not by time.strftime.

UPDATE Alternative using %, str.format:

>>> import time
>>> s, ms = divmod(1236472051807, 1000)  # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'

When there's no project, Code::Blocks only compiles and links the current file. That file, from your picture, is secrypt.cpp, which does not have a main function. In order to compile and link both source files, you'll need to do it manually or add them to the same project.

Contrary to what others are saying, using a Windows subsystem with main will still work, but there will be no console window.

Your other attempt, compiling and linking just trial.cpp, never links secrypt.cpp. This would normally result in an undefined reference to jRegister(), but you've declared the function inside main instead of calling it. Change main to:

int main()
{
    jRegister();

    return 0;
}

You can also try this pure CSS method:

1. I believe hibernate first translates your HQL query to SQL and only after that it tries to bind your parameters. Which means that it won't be able to rewrite query from param = ? to param is null.

2. Try using Criteria api:

   Criteria c = session.createCriteria(CountryDTO.class);
   c.add(Restrictions.eq("type", type));
   c.add(status == null ? Restrictions.isNull("status") : Restrictions.eq("status", status));
   List result = c.list();
   

I find myself using the following often to get a limited number of revisions out of our huge subversion tree (we're soon reaching svn revision 35000).

# checkout a specific revision
git svn clone -r N svn://some/repo/branch/some-branch
# enter it and get all commits since revision 'N'
cd some-branch
git svn rebase

And a good way to find out where a branch started is to do a svn log it and find the first one on the branch (the last one listed when doing):

svn log --stop-on-copy svn://some/repo/branch/some-branch

So far I have not really found the hassle worth it in tracking all branches. It takes too much time to clone and svn and git don't work together as good as I would like. I tend to create patch files and apply them on the git clone of another svn branch.

If you want to change a color to single column try this:

 dataGridView1.EnableHeadersVisualStyles = false;
 dataGridView1.Columns[0].HeaderCell.Style.BackColor = Color.Magenta;
 dataGridView1.Columns[1].HeaderCell.Style.BackColor = Color.Yellow;

If you used create-react-app to create your project then your public folder is accessible. So you need to add your image folder inside the public folder.

public/images/

<img src="/images/logo.png" />

As per the W3C:

Since the initial value of the border styles is 'none', no borders will be visible unless the border style is set.

In other words, you need to set a border style (e.g. solid) for the border to show up. border:thin only sets the width. Also, the color will by default be the same as the text color (which normally doesn't look good).

I recommend setting all three styles:

style="border: thin solid black"

and add to the .js file

require("@babel/register")

or if you run it in the cli, you could use the require hook as -r @babel/register, ex.

Restarting the database will flush your pool and that solves a effect not the problem.

Fixate your large_pool so it can not go lower then a certain point or add memory and set a higher max memory.

First create an instance of ObjectReader which is thread-safe.

ObjectMapper objectMapper = new ObjectMapper();
ObjectReader objectReader = objectMapper.reader().forType(new TypeReference<List<MyClass>>(){});

Then use it :

List<MyClass> result = objectReader.readValue(inputStream);

BASE_DIR = os.path.dirname(os.path.dirname(__file__))
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

The correct answer is this (example version):

• In parent pom.xml you should have (not inside properties):

  <version>0.0.1-SNAPSHOT</version>
  

• In all child modules you should have:

  <parent>
      <groupId>com.vvirlan</groupId>
      <artifactId>grafiti</artifactId>
      <version>0.0.1-SNAPSHOT</version>
  </parent>
  

So it is hardcoded.

Now, to update the version you do this:

mvn versions:set -DnewVersion=0.0.2-SNAPSHOT
mvn versions:commit # Necessary to remove the backup file pom.xml

and all your 400 modules will have the parent version updated.

In SQL Server (For last 24 hours):

SELECT  *
FROM    mytable
WHERE   order_date > DateAdd(DAY, -1, GETDATE()) and order_date<=GETDATE()

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

You can render anything using the conditional statement like if, else :

 render() {
    const price = this.state.price;
    let comp;

    if (price) {

      comp = <h1>Block for getting started with {this.state.price}</h1>

    } else {

      comp = <h1>Block for getting started.</h1>

    }

    return (
      <div>
        <div className="gettingStart">
          {comp}
        </div>
      </div>
    );
  }

Also make sure that the name of the variable is not some kind of a language keyword. For instance, the following produces the same type of error:

var history = [];
history.push("what a mess");

replacing it for:

var history123 = [];
history123.push("pray for a better language");

works as expected.

In case you get this error message in this situation:

• using github for entreprise
• using credential.helper=wincred in git config
• using your windows credentials which you changed recently

Then look at this answer: https://stackoverflow.com/a/39608906/521257

Windows stores credentials in a credentials manager, clear it or update it.

You could ignore SIGINTs after shutdown starts by calling signal.signal(signal.SIGINT, signal.SIG_IGN) before you start your cleanup code.

The solution here is to have different IDs as many of you have stated. The problem still lies deeper in datepicker. Please correct me, but doesn't the datepicker have one wrapper ID - "ui-datepicker-div." This is seen on http://jqueryui.com/demos/datepicker/#option-showOptions in the theming.

Is there an option that can change this ID to be a class? I don't want to have to fork this script just for this one obvious fix!!

Try this code. it worked for me.

 function getInvoiceID(url, invoiceId) {
    return $.ajax({
        type: 'POST',
        url: url,
        data: { invoiceId: invoiceId },
        async: false,
    });
}
function isInvoiceIdExists(url, invoiceId) {
    $.when(getInvoiceID(url, invoiceId)).done(function (data) {
        if (!data) {

        }
    });
}

When you put <form> tag inside you ngApp, AngularJS automatically adds form controller (actually there is a directive, called form that add nessesary behaviour). The value of the name attribute will be bound in your scope; so something like <form name="yourformname">...</form> will satisfy:

A form is an instance of FormController. The form instance can optionally be published into the scope using the name attribute.

So to check form validity, you can check value of $scope.yourformname.$valid property of scope.

More information you can get at Developer's Guide section about forms.

Apparently jQuery now provides jQuery.parseXML http://api.jquery.com/jQuery.parseXML/ as of version 1.5

jQuery.parseXML( data ) Returns: XMLDocument

SELECT IDENT_CURRENT('Table')

You can use one of these examples:

SELECT * FROM Table 
WHERE ID = (
    SELECT IDENT_CURRENT('Table'))

SELECT * FROM Table
WHERE ID = (
    SELECT MAX(ID) FROM Table)

SELECT TOP 1 * FROM Table
ORDER BY ID DESC

But the first one will be more efficient because no index scan is needed (if you have index on Id column).

The second one solution is equivalent to the third (both of them need to scan table to get max id).

I noticed "[" indexing columns fails to create levels when iterating:

for ( a_feature in convert.to.factors) {
feature.df[a_feature] <- factor(feature.df[a_feature]) }

It creates, e.g. for the "Status" column:

Status : Factor w/ 1 level "c(\"Success\", \"Fail\")" : NA NA NA ...

Which is remedied by using "[[" indexing:

for ( a_feature in convert.to.factors) {
feature.df[[a_feature]] <- factor(feature.df[[a_feature]]) }

Giving instead, as desired:

. Status : Factor w/ 2 levels "Success", "Fail" : 1 1 2 1 ...

Using git attributes, and filters setup with git config

OK, this is a new tack on solving this problem… My approach is to not use any hooks, but rather use filters and git attributes. What this allows you to do, is setup, on each machine you develop on, a set of filters that will strip extra trailing white space and extra blank lines at the end of files before committing them. Then setup a .gitattributes file that says which types of files the filter should be applied to. The filters have two phases, clean which is applied when adding files to the index, and smudge which is applied when adding them to the working directory.

Tell your git to look for a global attributes file

First, tell your global config to use a global attributes file:

git config --global core.attributesfile ~/.gitattributes_global

Create global filters

Now, create the filter:

git config --global filter.fix-eol-eof.clean fixup-eol-eof %f
git config --global filter.fix-eol-eof.smudge cat
git config --global filter.fix-eol-eof.required true

Add the sed scripting magic

Finally, put the fixup-eol-eof script somewhere on your path, and make it executable. The script uses sed to do some on the fly editing (remove spaces and blanks at the end of lines, and extraneous blank lines at the end of the file)

fixup-eol-eof should look like this:

#!/bin/bash
sed -e 's/[  ]*$//' -e :a -e '/^\n*$/{$d;N;ba' -e '}' $1

my gist of this

Tell git which file types to apply your newly created filter to

Lastly, create or open ~/.gitattributes_global in your favorite editor and add lines like:

pattern attr1 [attr2 [attr3 […]]]

So if we want to fix the whitespace issue, for all of our c source files we would add a line that looks like this:

*.c filter=fix-eol-eof

Discussion of the filter

The filter has two phases, the clean phase which is applied when things are added to the index or checked in, and the smudge phase when git puts stuff into your working directory. Here, our smudge is just running the contents through the cat command which should leave them unchanged, with the exception of possibly adding a trailing newline character if there wasn’t one at the end of the file. The clean command is the whitespace filtering which I cobbled together from notes at http://sed.sourceforge.net/sed1line.txt. It seems that it must be put into a shell script, I couldn’t figure out how to inject the sed command, including the sanitation of the extraneous extra lines at the end of the file directly into the git-config file. (You CAN get rid of trailing blanks, however, without the need of a separate sed script, just set the filter.fix-eol-eofto something like sed 's/[ \t]*$//' %f where the \t is an actual tab, by pressing tab.)

The require = true causes an error to be raised if something goes wrong, to keep you out of trouble.

Please forgive me if my language concerning git is imprecise. I think I have a fairly good grasp of the concepts but am still learning the terminology.

Try using Web API HttpClient

    static async Task RunAsync()

        using (var client = new HttpClient())

The workaround is

1. search and replace \r\n to thisismynewlineword

(this will remove all the new lines and there should be whole one line)

1. now perform your replacements

2. search and replace thisismynewlineword to \r\n

(to undo the step 1)

For "English locale" file names, this works nicely. I'm using this for sanitizing uploaded file names. The file name is not meant to be linked to anything on disk, it's for when the file is being downloaded hence there are no path checks.

$file_name = preg_replace('/([^\x20-~]+)|([\\/:?"<>|]+)/g', '_', $client_specified_file_name);

Basically it strips all non-printable and reserved characters for Windows and other OSs. You can easily extend the pattern to support other locales and functionalities.

Just create and add Python SDK

File -> Project Structure -> Project -> Project SDK -> new

and select the installation path of your Python interpreter (for example, C:\Python26 in windows and /usr/bin/python2.7 in Linux) as the home path.

Related discussion: http://devnet.jetbrains.net/thread/286883

Think of it this way.

Anything that you type after localhost/ is the path inside the root directory of your server(www or htdocs).

You don't need to specify the complete path of the file you want to run but just the path after the root folder because putting localhost/ takes you inside the root folder itself.

This actually sums it up pretty nicely.

API Levels generally mean that as a programmer, you can communicate with the devices' built in functions and functionality. As the API level increases, functionality adds up (although some of it can get deprecated).

Choosing an API level for an application development should take at least two thing into account:

1. Current distribution - How many devices can actually support my application, if it was developed for API level 9, it cannot run on API level 8 and below, then "only" around 60% of devices can run it (true to the date this post was made).
2. Choosing a lower API level may support more devices but gain less functionality for your app. you may also work harder to achieve features you could've easily gained if you chose higher API level.

Android API levels can be divided to five main groups (not scientific, but what the heck):

1. Android 1.5 - 2.3 (Cupcake to Gingerbread) - (API levels 3-10) - Android made specifically for smartphones.
2. Android 3.0 - 3.2 (Honeycomb) (API levels 11-13) - Android made for tablets.
3. Android 4.0 - 4.4 (KitKat) - (API levels 14-19) - A big merge with tons of additional functionality, totally revamped Android version, for both phone and tablets.
4. Android 5.0 - 5.1 (Lollipop) - (API levels 21-22) - Material Design introduced.
5. Android 6.0 - 6.… (Marshmallow) - (API levels 23-…) - Runtime Permissions,Apache HTTP Client Removed

I know this is an old question but I believed the asker wanted the class, not the class name. I wrote a little method that will get the actual class. It is sort of cheaty and may not always work, but sometimes when you need the actual class, you will have to use this method...

/**
     * Get the caller class.
     * @param level The level of the caller class.
     *              For example: If you are calling this class inside a method and you want to get the caller class of that method,
     *                           you would use level 2. If you want the caller of that class, you would use level 3.
     *
     *              Usually level 2 is the one you want.
     * @return The caller class.
     * @throws ClassNotFoundException We failed to find the caller class.
     */
    public static Class getCallerClass(int level) throws ClassNotFoundException {
        StackTraceElement[] stElements = Thread.currentThread().getStackTrace();
        String rawFQN = stElements[level+1].toString().split("\\(")[0];
        return Class.forName(rawFQN.substring(0, rawFQN.lastIndexOf('.')));
    }

This is what I ended up needing, in case someone finds it useful:

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ViewHolder(View item) {

        super(item);
        item.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("RecyclerView", "onClick:" + getAdapterPosition());
            }
        });

    }
}

In the absense of cache control directives that specify otherwise, a 301 redirect defaults to being cached without any expiry date.

That is, it will remain cached for as long as the browser's cache can accommodate it. It will be removed from the cache if you manually clear the cache, or if the cache entries are purged to make room for new ones.

You can verify this at least in Firefox by going to about:cache and finding it under disk cache. It works this way in other browsers including Chrome and the Chromium based Edge, though they don't have an about:cache for inspecting the cache.

In all browsers it is still possible to override this default behavior using caching directives, as described below:

If you don't want the redirect to be cached

This indefinite caching is only the default caching by these browsers in the absence of headers that specify otherwise. The logic is that you are specifying a "permanent" redirect and not giving them any other caching instructions, so they'll treat it as if you wanted it indefinitely cached.

The browsers still honor the Cache-Control and Expires headers like with any other response, if they are specified.

You can add headers such as Cache-Control: max-age=3600 or Expires: Thu, 01 Dec 2014 16:00:00 GMT to your 301 redirects. You could even add Cache-Control: no-cache so it won't be cached permanently by the browser or Cache-Control: no-store so it can't even be stored in temporary storage by the browser.

Though, if you don't want your redirect to be permanent, it may be a better option to use a 302 or 307 redirect. Issuing a 301 redirect but marking it as non-cacheable is going against the spirit of what a 301 redirect is for, even though it is technically valid. YMMV, and you may find edge cases where it makes sense for a "permanent" redirect to have a time limit. Note that 302 and 307 redirects aren't cached by default by browsers.

If you previously issued a 301 redirect but want to un-do that

If people still have the cached 301 redirect in their browser they will continue to be taken to the target page regardless of whether the source page still has the redirect in place. Your options for fixing this include:

• A simple solution is to issue another redirect back again.

  If the browser is directed back to a same URL a second time during a redirect, it should fetch it from the origin again instead of redirecting again from cache, in an attempt to avoid a redirect loop. Comments on this answer indicate this now works in all major browsers - but there may be some minor browsers where it doesn't.

• If you don't have control over the site where the previous redirect target went to, then you are out of luck. Try and beg the site owner to redirect back to you.

Prevention is better than cure - avoid a 301 redirect if you are not sure you want to permanently de-commission the old URL.

Does the basic HTML5 datalist work? It's clean and you don't have to play around with the messy third party code. W3SCHOOL tutorial

The MDN Documentation is very eloquent and features examples.

You can recursively revert like this:

svn revert --recursive .

There is no way (without writing a creative script) to remove things that aren't under source control. I think the closest you could do is to iterate over all of the files, use then grep the result of svn list, and if the grep fails, then delete it.

EDIT: The solution for the creative script is here: Automatically remove Subversion unversioned files

So you could create a script that combines a revert with whichever answer in the linked question suits you best.

When you just give make, it makes the first rule in your makefile, i.e "all". You have specified that "all" depends on "hello", which depends on main.o, factorial.o and hello.o. So 'make' tries to see if those files are present.

If they are present, 'make' sees if their dependencies, e.g. main.o has a dependency main.c, have changed. If they have changed, make rebuilds them, else skips the rule. Similarly it recursively goes on building the files that have changed and finally runs the top most command, "all" in your case to give you a executable, 'hello' in your case.

If they are not present, make blindly builds everything under the rule.

Coming to your problem, it isn't an error but 'make' is saying that every dependency in your makefile is up to date and it doesn't need to make anything!

You can use any of:

cd ~/"My Code"
cd ~/M"y Code"
cd ~/My" Code"

You cannot use:

cd ~"/My Code"

The first works because the shell expands ~/ into $HOME/, and then tacks on My Code without the double quotes. The second fails because there isn't a user called '"' (double quote) for ~" to map to.

SearchDialog or SearchWidget ?

When it comes to implement a search functionality there are two suggested approach by official Android Developer Documentation.
You can either use a SearchDialog or a SearchWidget.
I am going to explain the implementation of Search functionality using SearchWidget.

How to do it with Search widget ?

I will explain search functionality in a RecyclerView using SearchWidget. It's pretty straightforward.

Just follow these 5 Simple steps

1) Add searchView item in the menu

You can add SearchView can be added as actionView in menu using

app:useActionClass = "android.support.v7.widget.SearchView" .

<menu xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   tools:context="rohksin.com.searchviewdemo.MainActivity">
   <item
       android:id="@+id/searchBar"
       app:showAsAction="always"
       app:actionViewClass="android.support.v7.widget.SearchView"
   />
</menu>

2) Set up SerchView Hint text, listener etc

You should initialize SearchView in the onCreateOptionsMenu(Menu menu) method.

  @Override
  public boolean onCreateOptionsMenu(Menu menu) {
     // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);

        MenuItem searchItem = menu.findItem(R.id.searchBar);

        SearchView searchView = (SearchView) searchItem.getActionView();
        searchView.setQueryHint("Search People");
        searchView.setOnQueryTextListener(this);
        searchView.setIconified(false);

        return true;
   }

3) Implement SearchView.OnQueryTextListener in your Activity

OnQueryTextListener has two abstract methods

1. onQueryTextSubmit(String query)
2. onQueryTextChange(String newText

So your Activity skeleton would look like this

YourActivity extends AppCompatActivity implements SearchView.OnQueryTextListener{

     public boolean onQueryTextSubmit(String query)

     public boolean onQueryTextChange(String newText) 

}

4) Implement SearchView.OnQueryTextListener

You can provide the implementation for the abstract methods like this

public boolean onQueryTextSubmit(String query) {

    // This method can be used when a query is submitted eg. creating search history using SQLite DB

    Toast.makeText(this, "Query Inserted", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onQueryTextChange(String newText) {

    adapter.filter(newText);
    return true;
}

5) Write a filter method in your RecyclerView Adapter.

Most important part. You can write your own logic to perform search.
Here is mine. This snippet shows the list of Name which contains the text typed in the SearchView

public void filter(String queryText)
{
    list.clear();

    if(queryText.isEmpty())
    {
       list.addAll(copyList);
    }
    else
    {

       for(String name: copyList)
       {
           if(name.toLowerCase().contains(queryText.toLowerCase()))
           {
              list.add(name);
           }
       }

    }

   notifyDataSetChanged();
}

A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.

The Runnable Interface requires of the class to implement the method run() like so:

public class MyRunnableTask implements Runnable {
     public void run() {
         // do stuff here
     }
}

And then use it like this:

Thread t = new Thread(new MyRunnableTask());
t.start();

If you did not have the Runnable interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run() method in your class, so you could get errors. That is why you need to implement the interface.

Advanced: Anonymous Type

Note that you do not need to define a class as usual, you can do all of that inline:

Thread t = new Thread(new Runnable() {
    public void run() {
        // stuff here
    }
});
t.start();

This is similar to the above, only you don't create another named class.

This should work:

$("label[for='comedyclubs']")

Here is another solution using Jquery I find it a little easier and neater than inline JS sometimes.

    <html>
    <head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
    <script>

        /* if you prefer to functionize and use onclick= rather then the .on bind
        function hide_show(){
            $(this).hide();
            $("#hidden-div").show();
        }
        */

        $(function(){
            $("#chkbtn").on('click',function() {
                $(this).hide();
                $("#hidden-div").show();
            }); 
        });
    </script>
    <style>
    .hidden-div {
        display:none
    }
    </style>
    </head>
    <body>
    <div class="reform">
        <form id="reform" action="action.php" method="post" enctype="multipart/form-data">
        <input type="hidden" name="type" value="" />
            <fieldset>
                content here...
            </fieldset>

                <div class="hidden-div" id="hidden-div">

            <fieldset>
                more content here that is hidden until the button below is clicked...
            </fieldset>
        </form>
                </div>
                <span style="display:block; padding-left:640px; margin-top:10px;"><button id="chkbtn">Check Availability</button></span>
    </div>
    </body>
    </html>

    [idImagen] [int] IDENTITY (1, 1) NOT NULL
)

    CONSTRAINT [PK_ImagenesUsuario] PRIMARY KEY  CLUSTERED

Limiting the length of the input is definitely easier. You could accept an arbitrarily-long input by using a loop, reading in a bit at a time, re-allocating space for the string as necessary...

But that's a lot of work, so most C programmers just chop off the input at some arbitrary length. I suppose you know this already, but using fgets() isn't going to allow you to accept arbitrary amounts of text - you're still going to need to set a limit.

Use Simply this line code, there is no need to put anything in href attribute:

<a href="" onclick="window.history.go(-1)"> Go TO Previous Page</a>

If you use Java 8 and if it is possible that your search returns null, you could try using the Optional class.

To find a carnet:

private final Optional<Carnet> findCarnet(Collection<Carnet> yourList, String codeIsin){
    // This stream will simply return any carnet that matches the filter. It will be wrapped in a Optional object.
    // If no carnets are matched, an "Optional.empty" item will be returned
    return yourList.stream().filter(c -> c.getCodeIsin().equals(codeIsin)).findAny();
}

Now a usage for it:

public void yourMethod(String codeIsin){
    List<Carnet> listCarnet = carnetEJB.findAll();

    Optional<Carnet> carnetFound = findCarnet(listCarnet, codeIsin);

    if(carnetFound.isPresent()){
        // You use this ".get()" method to actually get your carnet from the Optional object
        doSomething(carnetFound.get());
    }
    else{
        doSomethingElse();
    }
}

Horizontal centering is as easy as:

text-align: center

Vertical centering when the container is a known height:

height: 100px;
line-height: 100px;
vertical-align: middle

Vertical centering when the container isn't a known height AND you can set the image in the background:

background: url(someimage) no-repeat center center;

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
   title  stage    jan    feb
0   darn  3.001  0.421  0.532
1     ok  2.829  1.036  0.751
2  three  1.115  1.146  2.921
>>> b
   title    mar    apr    may       jun  Unnamed: 5
0   darn  0.631  1.321  0.951    1.7510         NaN
1     ok  1.001  0.247  2.456    0.3216         NaN
2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510
1     ok  1.001  0.247  2.456    0.3216
2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged

This appears to be a bug in the way jQuery ships. You can fix it manually with some dom manipulation on the Dialog Open event:

$("#selector").dialog({
    open: function() {
        $(this).closest(".ui-dialog")
        .find(".ui-dialog-titlebar-close")
        .removeClass("ui-dialog-titlebar-close")
        .html("<span class='ui-button-icon-primary ui-icon ui-icon-closethick'></span>");
    }
});

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

This question is asked in a lot of places in a lot of different ways. I originally answered it here but I feel it's relevant in this thread as well (since i ended up here when I was searching for an answer).

There is no one line solution to this problem, but this worked for my use case. The problem is, the 'View(context, attrs, defStyle)' constructor does not refer to an actual style, it wants an attribute. So, we will:

1. Define an attribute
2. Create a style that you want to use
3. Apply a style for that attribute on our theme
4. Create new instances of our view with that attribute

In 'res/values/attrs.xml', define a new attribute:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="customTextViewStyle" format="reference"/>
    ...
</resources>    

In res/values/styles.xml' I'm going to create the style I want to use on my custom TextView

<style name="CustomTextView">
    <item name="android:textSize">18sp</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:paddingLeft">14dp</item>
</style>

In 'res/values/themes.xml' or 'res/values/styles.xml', modify the theme for your application / activity and add the following style:

<resources>
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <item name="@attr/customTextViewStyle">@style/CustomTextView</item>
    </style>
    ... 
</resources>

Finally, in your custom TextView, you can now use the constructor with the attribute and it will receive your style

public class CustomTextView extends TextView {

    public CustomTextView(Context context) {
       super(context, null, R.attr.customTextView);
    }
}

It's worth noting that I repeatedly used customTextView in different variants and different places, but it is in no way required that the name of the view match the style or the attribute or anything. Also, this technique should work with any custom view, not just TextViews.

You can use the .rows property and check it's .length, like this:

var rowCount = document.getElementById('myTableID').rows.length;

Eli Courtwright second solution is wrong, it should be:

Calendar c = Calendar.getInstance();
c.setTime(date);
c.add(Calendar.DATE, -days);
date.setTime(c.getTime().getTime());

I've never done it, but it looks like Reflection provides this. Field is an AnnotatedElement and so it has getAnnotation. This page has an example (copied below); quite straightforward if you know the class of the annotation and if the annotation policy retains the annotation at runtime. Naturally if the retention policy doesn't keep the annotation at runtime, you won't be able to query it at runtime.

An answer that's since been deleted (?) provided a useful link to an annotations tutorial that you may find helpful; I've copied the link here so people can use it.

Example from this page:

import java.lang.annotation.Retention; 
import java.lang.annotation.RetentionPolicy;
import java.lang.reflect.Method;

@Retention(RetentionPolicy.RUNTIME)
@interface MyAnno {
  String str();

  int val();
}

class Meta {
  @MyAnno(str = "Two Parameters", val = 19)
  public static void myMeth(String str, int i) {
    Meta ob = new Meta();

    try {
      Class c = ob.getClass();

      Method m = c.getMethod("myMeth", String.class, int.class);

      MyAnno anno = m.getAnnotation(MyAnno.class);

      System.out.println(anno.str() + " " + anno.val());
    } catch (NoSuchMethodException exc) {
      System.out.println("Method Not Found.");
    }
  }

  public static void main(String args[]) {
    myMeth("test", 10);
  }
}

Louth's answer works fine. But I don't think always return POSITION_NONE is a good idea. Because POSITION_NONE means that fragment should be destroyed and a new fragment will be created. You can check that in dataSetChanged function in the source code of ViewPager.

        if (newPos == PagerAdapter.POSITION_NONE) {
            mItems.remove(i);
            i--;
            ... not related code
            mAdapter.destroyItem(this, ii.position, ii.object);

So I think you'd better use an arraylist of weakReference to save all the fragments you have created. And when you add or remove some page, you can get the right position from your own arraylist.

 public int getItemPosition(Object object) {
    for (int i = 0; i < mFragmentsReferences.size(); i ++) {
        WeakReference<Fragment> reference = mFragmentsReferences.get(i);
        if (reference != null && reference.get() != null) {
            Fragment fragment = reference.get();
            if (fragment == object) {
                return i;
            }
        }
    }
    return POSITION_NONE;
}

According to the comments, getItemPosition is Called when the host view is attempting to determine if an item's position has changed. And the return value means its new position.

But this is not enought. We still have an important step to take. In the source code of FragmentStatePagerAdapter, there is an array named "mFragments" caches the fragments which are not destroyed. And in instantiateItem function.

if (mFragments.size() > position) {
        Fragment f = mFragments.get(position);
        if (f != null) {
            return f;
        }
    }

It returned the cached fragment directly when it find that cached fragment is not null. So there is a problem. From example, let's delete one page at position 2, Firstly, We remove that fragment from our own reference arraylist. so in getItemPosition it will return POSITION_NONE for that fragment, and then that fragment will be destroyed and removed from "mFragments".

 mFragments.set(position, null);

Now the fragment at position 3 will be at position 2. And instantiatedItem with param position 3 will be called. At this time, the third item in "mFramgents" is not null, so it will return directly. But actually what it returned is the fragment at position 2. So when we turn into page 3, we will find an empty page there.

To work around this problem. My advise is that you can copy the source code of FragmentStatePagerAdapter into your own project, and when you do add or remove operations, you should add and remove elements in the "mFragments" arraylist.

Things will be simpler if you just use PagerAdapter instead of FragmentStatePagerAdapter. Good Luck.

Like I said in the comments, you can use a function as module.exports. A function is also an object, so you don't have to change your syntax.

app.js

var controllers = require('./controllers')({app: app});

controllers.js

module.exports = function(params)
{
    return require('controllers/index')(params);
}

controllers/index.js

function controllers(params)
{
  var app = params.app;

  controllers.posts = require('./posts');

  controllers.index = function(req, res) {
    // code
  };
}

module.exports = controllers;

What I like about it is that it aligns the unit-of-work (as the user sees it - i.e. a page submit) with the unit-of-work in the ORM sense.

Therefore, you can make the entire page submission transactional, which you could not do if you were exposing CRUD methods with each creating a new context.

Python 3 ints do not have a maximum.

If your purpose is to determine the maximum size of an int in C when compiled the same way Python was, you can use the struct module to find out:

>>> import struct
>>> platform_c_maxint = 2 ** (struct.Struct('i').size * 8 - 1) - 1

If you are curious about the internal implementation details of Python 3 int objects, Look at sys.int_info for bits per digit and digit size details. No normal program should care about these.

If you are running local using spring i'd suggest use:

@Bean
public AmazonDynamoDB amazonDynamoDB() throws IOException {
    return AmazonDynamoDBClientBuilder.standard()
            .withCredentials(
                    new AWSStaticCredentialsProvider(
                            new BasicAWSCredentials("fake", "credencial")
                    )
            )
            .withClientConfiguration(new ClientConfigurationFactory().getConfig().withProtocol(Protocol.HTTP))
            .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("localhost:8443", "central"))
            .build();
}

It works for me using unit test.

Hope it's help!

From the Visual C++ help, I'd tend to go with

/* ACCESS.C: This example uses _access to check the
 * file named "ACCESS.C" to see if it exists and if
 * writing is allowed.
 */

#include  <io.h>
#include  <stdio.h>
#include  <stdlib.h>

void main( void )
{
   /* Check for existence */
   if( (_access( "ACCESS.C", 0 )) != -1 )
   {
      printf( "File ACCESS.C exists\n" );
      /* Check for write permission */
      if( (_access( "ACCESS.C", 2 )) != -1 )
         printf( "File ACCESS.C has write permission\n" );
   }
}

Also worth noting mode values of _access(const char *path,int mode):

• 00: Existence only

• 02: Write permission

• 04: Read permission

• 06: Read and write permission

As your fopen could fail in situations where the file existed but could not be opened as requested.

Edit: Just read Mecki's post. stat() does look like a neater way to go. Ho hum.

You can also write in this manner and it does the same. For eg:

for(int i=0;i < total; i++)
{
    pthread_join(pth[i],NULL);
    cout << "SUM of thread id " << pth[i] << " is " << args[i].sum << endl;
}

This program sets up an array of pthread_t and calculate sum on each. So it is printing the sum of each thread with thread id.

From MSDN:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

Moq cannot mock a static member of a class.

When designing code for testability it's important to avoid static members (and singletons). A design pattern that can help you refactoring your code for testability is Dependency Injection.

This means changing this:

public class Foo
{
    public Foo()
    {
        Bar = new Bar();
    }
}

to

public Foo(IBar bar)
{
    Bar = bar;
}

This allows you to use a mock from your unit tests. In production you use a Dependency Injection tool like Ninject or Unity wich can wire everything together.

I wrote a blog about this some time ago. It explains which patterns an be used for better testable code. Maybe it can help you: Unit Testing, hell or heaven?

Another solution could be to use the Microsoft Fakes Framework. This is not a replacement for writing good designed testable code but it can help you out. The Fakes framework allows you to mock static members and replace them at runtime with your own custom behavior.

Just change the routeReuseStrategy from the angular Router:

this._router.routeReuseStrategy.shouldReuseRoute = function () {
      return false;
    };

Set the routerproperty "navigated" to false:

this._router.navigated = false;

Then navigate to your component:

this._router.navigate(['routeToYourComponent'])

After that reinstate the old/default routeReuseStrategy:

this._router.routeReuseStrategy.shouldReuseRoute = function (future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
          return future.routeConfig === curr.routeConfig;

You can also make a service out of this:

@Injectable({
  providedIn: 'root'
})
export class RouterService {

  constructor(
    private _activatedRoute: ActivatedRoute,
    private _router: Router
  ) { }

  reuseRoutes(reuse: boolean) {
    if (!reuse) {
      this._router.routeReuseStrategy.shouldReuseRoute = function () {
        return false;
      };
    }
    if (reuse) {
      this._router.routeReuseStrategy.shouldReuseRoute = function (future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
        return future.routeConfig === curr.routeConfig;
      };
    }
  }

  async refreshPage(url?: string) {
    this._router.routeReuseStrategy.shouldReuseRoute = function () {
      return false;
    };

    this._router.navigated = false;

    url ? await this._router.navigate([url]) : await this._router.navigate([], { relativeTo: this._activatedRoute });

    this._router.routeReuseStrategy.shouldReuseRoute = function (future: ActivatedRouteSnapshot, curr: ActivatedRouteSnapshot): boolean {
      return future.routeConfig === curr.routeConfig;
    };
  }
}

Here is what I did

private void myEvent_Handler(object sender, SomeEvent e)
{
  // I dont know how many times this event will fire
  Task t = new Task(() =>
  {
    if (something == true) 
    {
        DoSomething(e);  
    }
  });
  t.RunSynchronously();
}

working great and not blocking UI thread

Using an in can have a performance impact. Joining two subqueries will not have the same performance impact and can be accomplished like this:

              ,Change_color
              ,play_file_name
              ,date_played
          FROM insert_log
         WHERE play_file_name NOT IN('Prompt1','Conclusion_Prompt_1','silent')
        ORDER BY callid ASC) t1
       JOIN (SELECT MAX(date_played) AS date_played
               FROM insert_log GROUP BY callid) t2
         ON t1.date_played = t2.date_played

1. Download your plugin
2. Open Eclipse
3. From the menu choose: Help / Install New Software...

5. In the Add Repository dialog that appears, click the Archive button next to the Location field
6. Select your plugin file, click OK

You could also just copy plugins to the eclipse/plugins directory, but it's not recommended.

To have your own scroll speed and flexibility to customize marquee properties, use the following:

<TextView

    android:ellipsize="marquee"
    android:fadingEdge="horizontal"
    android:lines="1"
    android:id="@+id/myTextView"
    android:padding="4dp"
    android:scrollHorizontally="true"
    android:singleLine="true"
    android:text="Simple application that shows how to use marquee, with a long text" />

Within your activity:

private void setTranslation() {
        TranslateAnimation tanim = new TranslateAnimation(
                TranslateAnimation.ABSOLUTE, 1.0f * screenWidth,
                TranslateAnimation.ABSOLUTE, -1.0f * screenWidth,
                TranslateAnimation.ABSOLUTE, 0.0f,
                TranslateAnimation.ABSOLUTE, 0.0f);
        tanim.setDuration(1000);
        tanim.setInterpolator(new LinearInterpolator());
        tanim.setRepeatCount(Animation.INFINITE);
        tanim.setRepeatMode(Animation.ABSOLUTE);

        textView.startAnimation(tanim);

Jordan Young's answer is the best. But if you can't or don't want to change your HTML, you might consider just removing the custom down arrow served to Chrome, Safari, etc and leaving firefox's default arrow - but without double arrows resulting. Not ideal, but a good quick fix that doesn't add any HTML and doesn't compromise your custom look in other browsers.

Our Server environment : SQL2008 x64 SP2 Reporting Services on Windows Server 2008 x64,

Client PC environment: Windows XP SP2 with IE6 or higher, all users are login to Active Directory, users are not members of local Administrator or power user group.

Error: When a user printing a report getting an error as "Unable to load client print control"

Solution that work for us: replace following files in sql 2008 with SQL 2008 R2

Program Files\Microsoft SQL Server\MSRS10.MSSQLSERVER\Reporting Services\ReportServer\bin RSClientPrint-x86.cab RSClientPrint-x64.cab RSClientPrint-ia64.cab

Once you replace the files one server users wont get above error and they do not required local power user or admin right to download Active X. Recommending to add report server URL as a trusted site (add to Trusted sites) via Active Directory GP.

Regarding Fred the Fantastic's answer:

Not every JPEG marker between C0-CF are SOF markers; I excluded DHT (C4), DNL (C8) and DAC (CC). Note that I haven't looked into whether it is even possible to parse any frames other than C0 and C2 in this manner. However, the other ones seem to be fairly rare (I personally haven't encountered any other than C0 and C2).

Either way, this solves the problem mentioned in comments by Malandy with Bangles.jpg (DHT erroneously parsed as SOF).

The other problem mentioned with 1431588037-WgsI3vK.jpg is due to imghdr only being able detect the APP0 (EXIF) and APP1 (JFIF) headers.

This can be fixed by adding a more lax test to imghdr (e.g. simply FFD8 or maybe FFD8FF?) or something much more complex (possibly even data validation). With a more complex approach I've only found issues with: APP14 (FFEE) (Adobe); the first marker being DQT (FFDB); and APP2 and issues with embedded ICC_PROFILEs.

Revised code below, also altered the call to imghdr.what() slightly:

import struct
import imghdr

def test_jpeg(h, f):
    # SOI APP2 + ICC_PROFILE
    if h[0:4] == '\xff\xd8\xff\xe2' and h[6:17] == b'ICC_PROFILE':
        print "A"
        return 'jpeg'
    # SOI APP14 + Adobe
    if h[0:4] == '\xff\xd8\xff\xee' and h[6:11] == b'Adobe':
        return 'jpeg'
    # SOI DQT
    if h[0:4] == '\xff\xd8\xff\xdb':
        return 'jpeg'
imghdr.tests.append(test_jpeg)

        if len(head) != 24:
            return
        what = imghdr.what(None, head)
        if what == 'png':
            check = struct.unpack('>i', head[4:8])[0]
            if check != 0x0d0a1a0a:

Note: Created a full answer instead of a comment, since I'm not yet allowed to.

In my copy, Shift + Tab does this, as long as I have a code selection, and am in a code window.

Maybe I missed it, but I couldn't find a complete answer on this page to the original question(s) because variables are not further discussed here. So I had to go on searching.

Since I'm not yet allowed to comment, let me add my conclusion here. I'm sure I was not the only one interested in it when accessing this page:

 >>>myString = 'Hello World'
 >>>end = 5

 >>>myString[2:end]
 'llo'

If you leave the first part, you get

 >>>myString[:end]
 'Hello' 

And if you left the : in the middle as well you got the simplest substring, which would be the 5th character (count starting with 0, so it's the blank in this case):

 >>>myString[end]
 ' '

I accidentally discarded changes in the Source Control in VS Code, I just needed to reopen this file and press Ctrl-Z few times, glad that VS Code saves your changes like that.

Changing my header to the following solve the problem:

<html>
<head>
<meta http-equiv="X-UA-Compatible" content="IE=Edge" />

Sometimes it takes longer to figure out the regex than to just write it out in python:

import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
    s = s.replace(char, ' ')

If you need other characters you can change it to use a white-list or extend your black-list.

Sample white-list:

whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
    if char in whitelist:
        new_s += char

A ViewGroup describes the layout of the Views in its group. The two basic examples of ViewGroups are LinearLayout and RelativeLayout. Breaking LinearLayout even further, you can have either Vertical LinearLayout or Horizontal LinearLayout. If you choose Vertical LinearLayout, your Views will stack vertically on your screen. The two most basic examples of Views are TextView and Button. Thus, if you have a ViewGroup of Vertical LinearLayout, your Views (e.g. TextViews and Buttons) would line up vertically down your screen.

When the other posters show nested ViewGroups, what they mean is, for example, one of the rows in my Vertical LinearLayout might actually, at the lower level, be several items arranged horizontally. In that case, I'd have a Horizontal LinearLayout as one of the children of my top level Vertical LinearLayout.

Example of Nested ViewGroups:
Parent ViewGroup = Vertical LinearLayout

Row1: TextView1
Row2: Button1
Row3: Image TextView2 Button2 <-- Horizontal Linear nested in Vertical Linear
Row4: TextView3
Row5: Button3

In short, the original purpose was to make a field which will be submitted with form's submit. Sometimes, there were need to store some information in hidden field(for example, id of user) and submit it with form's submit.

From HTML September 22, 1995 specification

An INPUT element with `TYPE=HIDDEN' represents a hidden field.The user does not interact with this field; instead, the VALUE attribute specifies the value of the field. The NAME and VALUE attributes are required.

If I understand the question: Couple "\r\n" to get that new line below in a textbox. My example worked -

   string s1 = comboBox1.Text;     // s1 is the variable assigned to box 1, etc.
   string s2 = comboBox2.Text;

   string both = s1 + "\r\n" + s2;
   textBox1.Text = both;

A typical answer could be s1 s2 in the text box using defined type style.

com.sun.mail.util.MailLogger is part of JavaMail API. It is already included in EE environment (that's why you can use it on your live server), but it is not included in SE environment.

Oracle docs:

The JavaMail API is available as an optional package for use with Java SE platform and is also included in the Java EE platform.

99% that you run your tests in SE environment which means what you have to bother about adding it manually to your classpath when running tests.

If you're using maven add the following dependency (you might want to change version):

<dependency>
    <groupId>com.sun.mail</groupId>
    <artifactId>javax.mail</artifactId>
    <version>1.6.0</version>
</dependency>

This ought to do it:

SELECT *
FROM YourTable
WHERE ARIDNR IN (
    SELECT ARIDNR
    FROM YourTable
    GROUP BY ARIDNR
    HAVING COUNT(*) > 1
)

The idea is to use the inner query to identify the records which have a ARIDNR value that occurs 1+ times in the data, then get all columns from the same table based on that set of values.

What about using the .click() function and the tag?

(Compressed version)

<a id="downloadtag" href="examplefolder/testfile.txt" hidden download></a>_x000D_
_x000D_
<button onclick="document.getElementById('downloadtag').click()">Download</button>

Now you can trigger it with js. It also doesn't open, as other examples, image and text files!

(js-function version)

function download(){_x000D_
document.getElementById('downloadtag').click();_x000D_
}

<!-- HTML -->_x000D_
<button onclick="download()">Download</button>_x000D_
<a id="downloadtag" href="coolimages/awsome.png" hidden download></a>

For doing this in iOS 7:

[[UINavigationBar appearance] setBarTintColor:myColor];

Faced with this same problem, I discovered if you have committed and/or pushed to remote since your successful cherry-pick, and you want to remove it, you can find the cherry-pick's SHA by running:

git log --graph --decorate --oneline

Then, (after using :wq to exit the log) you can remove the cherry-pick using

git rebase -p --onto YOUR_SHA_HERE^ YOUR_SHA_HERE

where YOUR_SHA_HERE equals the cherry-picked commit's 40- or abbreviated 7-character SHA.

At first, you won't be able to push your changes because your remote repo and your local repo will have different commit histories. You can force your local commits to replace what's on your remote by using

git push --force origin YOUR_REPO_NAME

(I adapted this solution from Seth Robertson: See "Removing an entire commit.")

You can also use,

parent.jQuery("#testdiv").attr("style", content from form);

My bible for JPA work is the Java Persistence wikibook. It has a section on unidirectional OneToMany which explains how to do this with a @JoinColumn annotation. In your case, i think you would want:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE")
private Set<Text> text;

I've used a Set rather than a List, because the data itself is not ordered.

The above is using a defaulted referencedColumnName, unlike the example in the wikibook. If that doesn't work, try an explicit one:

@OneToMany
@JoinColumn(name="TXTHEAD_CODE", referencedColumnName="DATREG_META_CODE")
private Set<Text> text;

You have installed a toolchain which was compiled for i686 on a box which is running an x86_64 userland.

Use an i686 VM.

Don't escape the underscore. Might be causing some whackness.

Then solution will be the following.

HTML

<div class="parent">
    <div class="child"></div>
</div>

CSS

.parent{
        width: 960px;
        margin: auto;
        height: 100vh
    }
    .child{
        position: absolute;
        width: 100vw
    }

I have gone through the same problem when I was using

    myApp.controller('mainController', ['$scope', function($scope,) {
        //$http was not working in this
    }]);

I have changed the above code to given below. Remember to include $http(2 times) as given below.

 myApp.controller('mainController', ['$scope','$http', function($scope,$http) {
      //$http is working in this
 }]);

and It has worked well.

Since you are providing a relative pathway to the image, the image location is looked for from the location in which you have the css file. So if you have the image in a different location to the css file you could either try giving the absolute URL(pathway starting from the root folder) or give the relative file location path. In your case since img and css are in the folder assets to move from location of css file to the img file, you can use '..' operator to refer that the browser has to move 1 folder back and then follow the pathway you have after the '..' operator. This is basically how relative pathway works and you can use it to access resoures in different folders. Hope it helps.

It's really a matter of efficiency, the overhead to insert, remove or move (where you are not simply swapping) elements inside a linked list is minimal, i.e. the operation itself is O(1), verses O(n) for an array. This can make a significant difference if you are operating heavily on a list of data. You chose your data-types based on how you will be operating on them and choose the most efficient for the algorithm you are using.

You will get this same error if there is not a Resource definition provided somewhere for your app -- most likely either in the central context.xml, or individual context file in conf/Catalina/localhost. And if using individual context files, beware that Tomcat freely deletes them anytime you remove/undeploy the corresponding .war file.

I had the app with multiple subdomains and session cookie was the problem between those. Clearing the cookies resolved my problem.

Also, try setting the SESSION_DOMAIN in .env file. Use the exact subdomain you are browsing.

A common use case where it can be used 'as is' is to override a class just to create a type (which is otherwise the same as the superclass), e.g.

class Error(Exception):
    pass

So you can raise and catch Error exceptions. What matters here is the type of exception, rather than the content.

I followed the previous answers and reinstalled node. But I got this error.

Warning: The post-install step did not complete successfully You can try again using brew postinstall node

So I ran this command

sudo chown -R $(whoami):admin /usr/local/lib/node_modules/

Then ran

brew postinstall node

Stroke font-character with a Less mixin

Here's a LESS mixin to generate the stroke: http://codepen.io/anon/pen/BNYGBy?editors=110

/// Stroke font-character
/// @param  {Integer} $stroke - Stroke width
/// @param  {Color}   $color  - Stroke color
/// @return {List}            - text-shadow list
.stroke(@stroke, @color) {
  @maxi: @stroke + 1;
  .i-loop (@i) when (@i > 0) {
    @maxj: @stroke + 1;
    .j-loop (@j) when (@j > 0) {
      text-shadow+: (@i - 1)*(1px)  (@j - 1)*(1px) 0 @color;
      text-shadow+: (@i - 1)*(1px)  (@j - 1)*(-1px) 0 @color;
      text-shadow+: (@i - 1)*(-1px)  (@j - 1)*(-1px) 0 @color;
      text-shadow+: (@i - 1)*(-1px)  (@j - 1)*(1px) 0 @color;
      .j-loop(@j - 1);
    }
    .j-loop (0) {}
    .j-loop(@maxj);
    .i-loop(@i - 1);
  }
  .i-loop (0) {}
  .i-loop(@maxi);
  text-shadow+: 0 0 0 @color;
}

(it's based on pixelass answer that instead uses SCSS)

I thought I could add a method I use in many projects.

- (NSInteger)randomValueBetween:(NSInteger)min and:(NSInteger)max {
    return (NSInteger)(min + arc4random_uniform(max - min + 1));
}

If I end up using it in many files I usually declare a macro as

#define RAND_FROM_TO(min, max) (min + arc4random_uniform(max - min + 1))

E.g.

NSInteger myInteger = RAND_FROM_TO(0, 74) // 0, 1, 2,..., 73, 74

Note: Only for iOS 4.3/OS X v10.7 (Lion) and later

I'm using org.apache.commons.fileupload.servlet.ServletFileUpload.ServletFileUpload(FileItemFactory) and defining the encoding when reading out parameter value:

List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);

for (FileItem item : items) {
    String fieldName = item.getFieldName();

    if (item.isFormField()) {
        String fieldValue = item.getString("UTF-8"); // <-- HERE

This is not very difficult to implement yourself:

function reduceObj(obj, callback, initial) {
    "use strict";
    var key, lastvalue, firstIteration = true;
    if (typeof callback !== 'function') {
        throw new TypeError(callback + 'is not a function');
    }   
    if (arguments.length > 2) {
        // initial value set
        firstIteration = false;
        lastvalue = initial;
    }
    for (key in obj) {
        if (!obj.hasOwnProperty(key)) continue;
        if (firstIteration)
            firstIteration = false;
            lastvalue = obj[key];
            continue;
        }
        lastvalue = callback(lastvalue, obj[key], key, obj);
    }
    if (firstIteration) {
        throw new TypeError('Reduce of empty object with no initial value');
    }
    return lastvalue;
}

In action:

var o = {a: {value:1}, b: {value:2}, c: {value:3}};
reduceObj(o, function(prev, curr) { prev.value += cur.value; return prev;}, {value:0});
reduceObj(o, function(prev, curr) { return {value: prev.value + curr.value};});
// both == { value: 6 };

reduceObj(o, function(prev, curr) { return prev + curr.value; }, 0);
// == 6

You can also add it to the Object prototype:

if (typeof Object.prototype.reduce !== 'function') {
    Object.prototype.reduce = function(callback, initial) {
        "use strict";
        var args = Array.prototype.slice(arguments);
        args.unshift(this);
        return reduceObj.apply(null, args);
    }
}

First malloc allocates memory for struct, including memory for x (pointer to double). Second malloc allocates memory for double value wtich x points to.

If you are able to use JavaScript, then this script may be what you are looking for. It works cross browser and is working fine for me so far. You can't use it with images loaded from a different domain.

http://james.padolsey.com/demos/grayscale/

public static void copyFolder(File source, File destination)
{
    if (source.isDirectory())
    {
        if (!destination.exists())
        {
            destination.mkdirs();
        }

        String files[] = source.list();

        for (String file : files)
        {
            File srcFile = new File(source, file);
            File destFile = new File(destination, file);

            copyFolder(srcFile, destFile);
        }
    }
    else
    {
        InputStream in = null;
        OutputStream out = null;

        try
        {
            in = new FileInputStream(source);
            out = new FileOutputStream(destination);

            byte[] buffer = new byte[1024];

            int length;
            while ((length = in.read(buffer)) > 0)
            {
                out.write(buffer, 0, length);
            }
        }
        catch (Exception e)
        {
            try
            {
                in.close();
            }
            catch (IOException e1)
            {
                e1.printStackTrace();
            }

            try
            {
                out.close();
            }
            catch (IOException e1)
            {
                e1.printStackTrace();
            }
        }
    }
}

This flexbox principle also works horizontally

During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Setting an automatic left margin for the Last Item will do the work.

.last-item {
  margin-left: auto;
}

Code Example:

.container {_x000D_
  display: flex;_x000D_
  width: 400px;_x000D_
  outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  margin: 5px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
  margin-left: auto;_x000D_
}

<div class="container">_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p class="last-item"></p>_x000D_
</div>

Codepen Snippet

This can be very useful for Desktop Footers.

Codepen Snippet

Perhaps the best choice to avoid linking containers issues are the docker networking features

But to make this work, docker creates entries in the /etc/hosts for each container from assigned names to each container.

with docker-compose --x-networking -up is something like [docker_compose_folder]-[service]-[incremental_number]

To not depend on unexpected changes in these names you should use the parameter

container_name

in your docker-compose.yml as follows:

php:
      container_name: waapi_php_1
      build: config/docker/php
      ports:
        - "42022:22"
      volumes:
        - .:/var/www/html
      env_file: config/docker/php/.env.development

Making sure that it is the same name assigned in your configuration file for this service. I'm pretty sure there are better ways to do this, but it is a good approach to start.

As best place and practice for external API calls is React Lifecycle method componentDidMount(), where after the execution of the API call you should update the local state to be triggered new render() method call, then the changes in the updated local state will be applied on the component view.

As other option for initial external data source call in React is pointed the constructor() method of the class. The constructor is the first method executed on initialization of the component object instance. You could see this approach in the documentation examples for Higher-Order Components.

The method componentWillMount() and UNSAFE_componentWillMount() should not be used for external API calls, because they are intended to be deprecated. Here you could see common reasons, why this method will be deprecated.

Anyway you must never use render() method or method directly called from render() as a point for external API call. If you do this your application will be blocked.

So all of these answers are basically the same one. They only address one idea: it has to be DNS related. Well, that is not the only part of this it turns out. After many changes, I was getting nowhere reading the next "same answer" hoping that it would just go my way.

What did the trick for me was to adjust my versions of Apache. I think what the deal was, is that the one of the configuration files get a path off or that the install due to IIS may have been messed up / or / or /etc. And so forcing a version change readdresses everything from your firewall to bad configurations.

In fact, when I switched back to Apache 2.4.2 it goes back to being a forbidden. And as soon as I go back to Apache 2.4.4 it comes back up. That rules out local network issues. I just wanted to point out that all of the answers here are the same and that I have been able to kill the forbidden by changing the Apache version.

That's strange, it definitely works for me:

from matplotlib import pyplot as plt

plt.figure(figsize = (20,2))
plt.imshow(random.rand(8, 90), interpolation='nearest')

I am using the "MacOSX" backend, btw.

In Laravel the default environment is always production.

What you need to do is to specify correct hostname in bootstrap/start.php for your enviroments eg.:

/*
|--------------------------------------------------------------------------
| Detect The Application Environment
|--------------------------------------------------------------------------
|
| Laravel takes a dead simple approach to your application environments
| so you can just specify a machine name for the host that matches a
| given environment, then we will automatically detect it for you.
|
*/

$env = $app->detectEnvironment(array(
    'local' => array('homestead'),
    'profile_1' => array('hostname_for_profile_1')
));

You can redirect output to a file and then read the file:

return = WshShell.Run("cmd /c C:\snmpset -c ... > c:\temp\output.txt", 0, true)

Set fso  = CreateObject("Scripting.FileSystemObject")
Set file = fso.OpenTextFile("c:\temp\output.txt", 1)
text = file.ReadAll
file.Close

If we use=> .equals method

if(obj.equals(null))  

// Which mean null.equals(null) when obj will be null.

When your obj will be null it will throw Null Point Exception.

so we should use ==

if(obj == null)

it will compare the references.

I noticed some issues with this that might be useful for someone just starting, or a somewhat inexperienced user, to know. First...

CD /D "C:\Documents and Settings\%username%\Start Menu\Programs\"

two things one is that a /D after the CD may prove to be useful in making sure the directory is changed but it's not really necessary, second, if you are going to pass this from user to user you have to add, instead of your name, the code %username%, this makes the code usable on any computer, as long as they have your setup.exe file in the same location as you do on your computer. of course making sure of that is more difficult. also...

start \\filer\repo\lab\"software"\"myapp"\setup.exe

the start code here, can be set up like that, but the correct syntax is

start "\\filter\repo\lab\software\myapp\" setup.exe

This will run: setup.exe, located in: \filter\repo\lab...etc.\

Run it through a fairly simple regex: [^a-zA-Z]

And then check it's length separately:

if(string.Length > 7)

You can use self.data in the clean_email method to access the POST data before validation. It should contain a key called newsletter_sub or newsletter_unsub depending on which button was pressed.

# in the context of a django.forms form

def clean(self):
    if 'newsletter_sub' in self.data:
        # do subscribe
    elif 'newsletter_unsub' in self.data:
        # do unsubscribe

The quirky syntax using conditions on the target (described by Mads) is the only supported way to perform conditional execution in core ANT.

ANT is not a programming language and when things get complicated I choose to embed a script within my build as follows:

<target name="prepare-copy" description="copy file based on condition">
    <groovy>
        if (properties["some.condition"] == "true") {
            ant.copy(file:"${properties["some.dir"]}/true", todir:".")
        }
    </groovy>
</target>

ANT supports several languages (See script task), my preference is Groovy because of it's terse syntax and because it plays so well with the build.

Apologies, David I am not a fan of ant-contrib.

Here is some supplemental literature on keepalive which explains it in much finer detail.

http://www.tldp.org/HOWTO/html_single/TCP-Keepalive-HOWTO

Since Java does not allow you to control the actual keepalive times, you can use the examples to change them if you're using a Linux kernel (or proc based OS).

After "AND" and after "OR" the QUERY has forgotten what it is all about.

I would also not know that it is about in any SQL / programming language.

if(SOMETHING equals "X" or SOMETHING equals "Y")

COLUMN NOT LIKE "A%" AND COLUMN NOT LIKE "B%"

Finally my issue got resolved. I was importing the project as "Existing project into workspace". This was completely wrong. After that I selected "Existing Maven project" and after that some few hiccups and all errors were removed. In this process I got to learn so many things in Maven which are important for a new comer in Maven project.

There are a couple of things that need to be adjusted in your layout:

1. You are nesting col elements within form-group elements. This should be the other way around (the form-group should be within the col-sm-xx element).

2. You should always use a row div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12 is still on the same row with the above 3 .col-sm-4 resulting in a total of columns greater than 12, and causing the overlap problem.

Here is a fixed demo.

And an excerpt of what the problematic section HTML should become:

<fieldset>
    <legend>Personal Information</legend>
    <div class='row'>
        <div class='col-sm-4'>    
            <div class='form-group'>
                <label for="user_title">Title</label>
                <input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_firstname">First name</label>
                <input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />
            </div>
        </div>

It isn't valid to have the same ID twice, that's why #name only finds the first one.

You can try:

$("#form2 input").val('Hello World!');

Or,

$("#form2 input[name=name]").val('Hello World!');

If you're stuck with an invalid page and want to select all #names, you can use the attribute selector on the id:

$("input[id=name]").val('Hello World!');

export default function useQueryParams() {
  const params = new URLSearchParams(window.location.search)

  return new Proxy(params, {
    get(target, prop) {
      return target.get(prop);
    },
  });
}

The guy that did AForge did a fairly good job but it's not commercial quality. It's great to learn from but you can tell he was learning too so he has some pretty serious mistakes like assuming the size of an image instead of using the correct bits per pixel.

I'm not knocking the guy, I respect the heck out of him for learning all that and show us how to do it. I think he's a Ph.D now or at least he's about to be so he's really smart it's just not a commercially usable library.

The Math.Net library has its own weirdness when working with Fourier transforms and complex images/numbers. Like, if I'm not mistaken, it outputs the Fourier transform in human viewable format which is nice for humans if you want to look at a picture of the transform but it's not so good when you are expecting the data to be in a certain format (the normal format). I could be mistaken about that but I just remember there was some weirdness so I actually went to the original code they used for the Fourier stuff and it worked much better. (ExocortexDSP v1.2 http://www.exocortex.org/dsp/)

Math.net also had some other funkyness I didn't like when dealing with the data from the FFT, I can't remember what it was I just know it was much easier to get what I wanted out of the ExoCortex DSP library. I'm not a mathematician or engineer though; to those guys it might make perfect sense.

So! I use the FFT code yanked from ExoCortex, which Math.Net is based on, without anything else and it works great.

And finally, I know it's not C#, but I've started looking at using FFTW (http://www.fftw.org/). And this guy already made a C# wrapper so I was going to check it out but haven't actually used it yet. (http://www.sdss.jhu.edu/~tamas/bytes/fftwcsharp.html)

Simply changing

public int compare(Dog d, Dog d1) {
  return d.age - d1.age;
}

to

public int compare(Dog d, Dog d1) {
  return d1.age - d.age;
}

should sort them in the reverse order of age if that is what you are looking for.

Update:

@Arian is right in his comments, one of the accepted ways of declaring a comparator for a dog would be where you declare it as a public static final field in the class itself.

class Dog implements Comparable<Dog> {
    private String name;
    private int age;

    public static final Comparator<Dog> DESCENDING_COMPARATOR = new Comparator<Dog>() {
        // Overriding the compare method to sort the age
        public int compare(Dog d, Dog d1) {
            return d.age - d1.age;
        }
    };

    Dog(String n, int a) {
        name = n;
        age = a;
    }

    public String getDogName() {
        return name;
    }

    public int getDogAge() {
        return age;
    }

    // Overriding the compareTo method
    public int compareTo(Dog d) {
        return (this.name).compareTo(d.name);
    }

}

You could then use it any where in your code where you would like to compare dogs as follows:

// Sorts the array list using comparator
Collections.sort(list, Dog.DESCENDING_COMPARATOR);

Another important thing to remember when implementing Comparable is that it is important that compareTo performs consistently with equals. Although it is not required, failing to do so could result in strange behaviour on some collections such as some implementations of Sets. See this post for more information on sound principles of implementing compareTo.

Update 2: Chris is right, this code is susceptible to overflows for large negative values of age. The correct way to implement this in Java 7 and up would be Integer.compare(d.age, d1.age) instead of d.age - d1.age.

Update 3: With Java 8, your Comparator could be written a lot more succinctly as:

public static final Comparator<Dog> DESCENDING_COMPARATOR = 
    Comparator.comparing(Dog::getDogAge).reversed();

The syntax for Collections.sort stays the same, but compare can be written as

public int compare(Dog d, Dog d1) {
    return DESCENDING_COMPARATOR.compare(d, d1);
}

May be too late to answer, but at least some one will get help.

You can try two options:

This is the result when you want to assign based on index value, where '0' is Index.

 $('#mySelect').prop('selectedIndex', 0);

don't use 'attr' since it is deprecated with latest jquery.

When you want to select based on option value then choose this :

 $('#mySelect').val('fg');

where 'fg' is the option value

You should read up on the onclick html attribute and the window.open() documentation. Below is what you want.

If you are making local changes to a javascript in the Developer Tools, you need to make sure that you turn OFF those changes before reloading the page.

In the Sources tab, with your script open, right-click in your script and click the "Local Modifications" option from the context menu. That brings up the list of scripts you've saved modifications to. If you see it in that window, Developer Tools will always keep your local copy rather than refreshing it from the server. Click the "revert" button, then refresh again, and you should get the fresh copy.

This will draw a line that passes through the points (-1, 1) and (12, 4), and another one that passes through the points (1, 3) et (10, 2)

x1 are the x coordinates of the points for the first line, y1 are the y coordinates for the same -- the elements in x1 and y1 must be in sequence.

x2 and y2 are the same for the other line.

import matplotlib.pyplot as plt
x1, y1 = [-1, 12], [1, 4]
x2, y2 = [1, 10], [3, 2]
plt.plot(x1, y1, x2, y2, marker = 'o')
plt.show()

I suggest you spend some time reading / studying the basic tutorials found on the very rich matplotlib website to familiarize yourself with the library.

What if I don't want line segments?

There are no direct ways to have lines extend to infinity... matplotlib will either resize/rescale the plot so that the furthest point will be on the boundary and the other inside, drawing line segments in effect; or you must choose points outside of the boundary of the surface you want to set visible, and set limits for the x and y axis.

As follows:

import matplotlib.pyplot as plt
x1, y1 = [-1, 12], [1, 10]
x2, y2 = [-1, 10], [3, -1]
plt.xlim(0, 8), plt.ylim(-2, 8)
plt.plot(x1, y1, x2, y2, marker = 'o')
plt.show()

Me too got the same error but in my case I was calling url with blank spaces.

Then, I fixed it by parsing like below.

String url = "Your URL Link";

url = url.replaceAll(" ", "%20");

StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
                            new com.android.volley.Response.Listener<String>() {
                                @Override
                                public void onResponse(String response) {
                                ...
                                ...
                                ...

SomeProperty.HasValue I think it's what you're looking for.

EDIT : btw, you can write System.Guid? instead of Nullable<System.Guid> ;)

end as converted_date

In this query, I worked out the result came from current date of the day.

Create this class:

public class StdOutErrLog {

private static final Logger logger = Logger.getLogger(StdOutErrLog.class);

public static void tieSystemOutAndErrToLog() {
    System.setOut(createLoggingProxy(System.out));
    System.setErr(createLoggingProxy(System.err));
}

public static PrintStream createLoggingProxy(final PrintStream realPrintStream) {
    return new PrintStream(realPrintStream) {
        public void print(final String string) {
            logger.info(string);
        }
        public void println(final String string) {
            logger.info(string);
        }
    };
}
}

Call this in your code

StdOutErrLog.tieSystemOutAndErrToLog();

I got this error then restarted my GlassFish server that held connection pools between my client app and the database, and the error went away. So, try restarting your application server if applicable.

//This c# method will check for even and odd lengh palindrome string

public static bool IsPalenDrome(string palendromeString)
        {
            bool isPalenDrome = false;

            try
            {
                int halfLength = palendromeString.Length / 2;

                string leftHalfString = palendromeString.Substring(0,halfLength);

                char[] reversedArray = palendromeString.ToCharArray();
                Array.Reverse(reversedArray);
                string reversedString = new string(reversedArray);

                string rightHalfStringReversed = reversedString.Substring(0, halfLength);

                isPalenDrome = leftHalfString == rightHalfStringReversed ? true : false;
            }

            {

Per the docs, replace returns the new string - it does not modify the string you pass it.

jQuery Mobile >= 1.4

Create a custom class, e.g. .custom-btn. Note that to override jQM styles without using !important, CSS hierarchy should be respected. .ui-btn.custom-class or .ui-input-btn.custom-class.

.ui-input-btn.custom-btn {
   border:1px solid red;
   text-decoration:none;
   font-family:helvetica;
   color:red;
   background:url(img.png) repeat-x;
}

Add a data-wrapper-class to input. The custom class will be added to input wrapping div.

<input type="button" data-wrapper-class="custom-btn">

Demo

jQuery Mobile <= 1.3

Input button is wrapped by a DIV with class ui-btn. You need to select that div and the input[type="submit"]. Using !important is essential to override Jquery Mobile styles.

Demo

div.ui-btn, input[type="submit"] {
 border:1px solid red !important;
 text-decoration:none !important;
 font-family:helvetica !important;
 color:red !important;
 background:url(../images/btn_hover.png) repeat-x !important;
}

We can use enum type for this.We don't require a library. For example

           enum {false,true};

the value for false will be 0 and the value for true will be 1.

If you want to do it the way you showed in your question, this is a way to do it inline

class YourClass: UIViewController{

  @IBOutlet weak var tableView: UITableView!
  //other IBOutlets

  //THIS is how you declare a UIImageView inline
  let placeholderImage : UIImageView = {
        let placeholderImage = UIImageView(image: UIImage(named: "nophoto"))
        placeholderImage.contentMode = .scaleAspectFill
        return placeholderImage
    }()

   var someVariable: String!
   var someOtherVariable: Int!

   func someMethod(){
      //method code
   }

   //and so on
}

The short answer is: don't. (...) You really can't. And that's a good thing

I'd like to set the record straight regarding this:

NodeJS does support Synchronous Requests. It wasn't designed to support them out of the box, but there are a few workarounds if you are keen enough, here is an example:

var request = require('sync-request'),
    res1, res2, ucomp, vcomp;

try {
    res1 = request('GET', base + u_ext);
    res2 = request('GET', base + v_ext);
    ucomp = res1.split('\n')[1].split(', ')[1];
    vcomp = res2.split('\n')[1].split(', ')[1];
    doSomething(ucomp, vcomp);

} catch (e) {}

When you pop the hood open on the 'sync-request' library you can see that this runs a synchronous child process in the background. And as is explained in the sync-request README it should be used very judiciously. This approach locks the main thread, and that is bad for performance.

However, in some cases there is little or no advantage to be gained by writing an asynchronous solution (compared to the certain harm you are doing by writing code that is harder to read).

This is the default assumption held by many of the HTTP request libraries in other languages (Python, Java, C# etc), and that philosophy can also be carried to JavaScript. A language is a tool for solving problems after all, and sometimes you may not want to use callbacks if the benefits outweigh the disadvantages.

For JavaScript purists this may rankle of heresy, but I'm a pragmatist so I can clearly see that the simplicity of using synchronous requests helps if you find yourself in some of the following scenarios:

1. Test Automation (tests are usually synchronous by nature).

2. Quick API mash-ups (ie hackathon, proof of concept works etc).

3. Simple examples to help beginners (before and after).

Be warned that the code above should not be used for production. If you are going to run a proper API then use callbacks, use promises, use async/await, or whatever, but avoid synchronous code unless you want to incur a significant cost for wasted CPU time on your server.

int num = int.Parse(textBox.Text);

try this. It worked for me

I made a library that makes this a lot easier. Check out ZenCopy.

You can create Style objects, and/or set them to keys to reference later. Like this:

ZenCopy.manager.config.setStyles {
    return [
        "token": Style(
            color: .blueColor(), // optional
            // fontName: "Helvetica", // optional
            fontSize: 14 // optional
        )
    ]
}

Then, you can easily construct strings AND style them AND have params :)

label.attributedText = attributedString(
                                ["$0 ".style("token") "is dancing with ", "$1".style("token")], 
                          args: ["JP", "Brock"]
)

You can also style things easily with regex searches!

let atUserRegex = "(@[A-Za-z0-9_]*)"
mutableAttributedString.regexFind(atUserRegex, addStyle: "token")

This will style all words with '@' in front of it with the 'token' style. (e.g. @jpmcglone)

I need to still get it working w/ everything NSAttributedString has to offer, but I think fontName, fontSize and color cover the bulk of it. Expect lots of updates soon :)

I can help you get started with this if you need. Also looking for feedback, so if it makes your life easier, I'd say mission accomplished.

You can use this function

function getParmFromUrl(url, parm) {
    var re = new RegExp(".*[?&]" + parm + "=([^&]+)(&|$)");
    var match = url.match(re);
    return(match ? match[1] : "");
}

If you want to browse to a folder by default: For example "D:\Default_Folder" just initialise the "InitialFileName" attribute

Dim diaFolder As FileDialog

' Open the file dialog
Set diaFolder = Application.FileDialog(msoFileDialogFolderPicker)
diaFolder.AllowMultiSelect = False
diaFolder.InitialFileName = "D:\Default_Folder"
diaFolder.Show

I tried many ways and came up with my own solution which works absolutely as required.

"mydate" is the ID of input or datepicker element/control.

        $(document).ready(function () {

        var dateNewFormat, onlyDate, today = new Date();

        dateNewFormat = today.getFullYear() + '-' + (today.getMonth() + 1);

        onlyDate = today.getDate();

        if (onlyDate.toString().length == 2) {
            dateNewFormat += '-' + onlyDate;
        }
        else {
            dateNewFormat += '-0' + onlyDate;
        }
        $('#mydate').val(dateNewFormat);
    });

You should have a div that just contains the console messages, that is, previous commands and their output. And underneath put an input or textarea that just holds the command you are typing.

-------------------------------
| consle output ...           |
| more output                 |
| prevous commands and data   |
-------------------------------
> This is an input box.

That way you just send the value of the input box to the server for processing, and append the result to the console messages div.

In updateColumns() need if (column >= columns.length) rather than if (column > columns.length) to list all elements (C is skipped for example) so:

function updateColumns(){
    column = 0;
    columnItems.each(function(idx, el){
        if (column >= columns.length){
            column = 0;
        }
        console.log(column, el, idx);
        $(columns.get(column)).append(el);
        column += 1;
    });
}

You can use the this customization to change the default mapping to java.util.Date

<xsd:annotation>
<xsd:appinfo>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:dateTime"
                 parseMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.parseDateTime"
                 printMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.printDateTime"/>
    </jaxb:globalBindings>
</xsd:appinfo>

Somehow Zacharias solution didn't work for me so I have used the below theme to resolve this issue...

<style name="DialogCustomTheme" parent="android:Theme.Holo.Dialog.NoActionBar">
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:colorBackgroundCacheHint">@null</item>
</style>

One can set this theme to dialog as below

final Dialog dialog = new Dialog(this, R.style.DialogCustomTheme); 

Enjoy!!

There are a number of JavaScript obfuscation tools that are freely available; however, I think it's important to note that it is difficult to obfuscate JavaScript to the point where it cannot be reverse-engineered.

To that end, there are several options that I've used to some degree overtime:

• YUI Compressor. Yahoo!'s JavaScript compressor does a good job of condensing the code that will improve its load time. There is a small level of obfuscation that works relatively well. Essentially, Compressor will change function names, remove white space, and modify local variables. This is what I use most often. This is an open-source Java-based tool.

• JSMin is a tool written by Douglas Crockford that seeks to minify your JavaScript source. In Crockford's own words, "JSMin does not obfuscate, but it does uglify." It's primary goal is to minify the size of your source for faster loading in browsers.

• Free JavaScript Obfuscator. This is a web-based tool that attempts to obfuscate your code by actually encoding it. I think that the trade-offs of its form of encoding (or obfuscation) could come at the cost of filesize; however, that's a matter of personal preference.

I fixed it like this example.

$scope.myCalendar = new Date(myUnixDate*1000);
<input date-time ng-model="myCalendar" format="DD/MM/YYYY" />

You can use IN operator as below

select * from dbo.books where isbn IN
(select isbn from dbo.lending where lended_date between @fdate and @tdate)

Just one line will be OK.

While moopasta's answer works, it doesn't appear to allow wildcards and there is another (potentially better) option. The Chromium project has some HTTP authentication documentation that is useful but incomplete.

Specifically the option that I found best is to whitelist sites that you would like to allow Chrome to pass authentication information to, you can do this by:

• Launching Chrome with the auth-server-whitelist command line switch. e.g. --auth-server-whitelist="*example.com,*foobar.com,*baz". Downfall to this approach is that opening links from other programs will launch Chrome without the command line switch.
• Installing, enabling, and configuring the AuthServerWhitelist/"Authentication server whitelist" Group Policy or Local Group Policy. This seems like the most stable option but takes more work to setup. You can set this up locally, no need to have this remotely deployed.

Those looking to set this up for an enterprise can likely follow the directions for using Group Policy or the Admin console to configure the AuthServerWhitelist policy. Those looking to set this up for one machine only can also follow the Group Policy instructions:

1. Download and unzip the latest Chrome policy templates
2. Start > Run > gpedit.msc
3. Navigate to Local Computer Policy > Computer Configuration > Administrative Templates
4. Right-click Administrative Templates, and select Add/Remove Templates
5. Add the windows\adm\en-US\chrome.adm template via the dialog
6. In Computer Configuration > Administrative Templates > Classic Administrative Templates > Google > Google Chrome > Policies for HTTP Authentication enable and configure Authentication server whitelist
7. Restart Chrome and navigate to chrome://policy to view active policies

1. To use pip for a python 2.x environment, use this command -

   py -2 -m pip install -r requirements.txt

2. To use pip for python 3.x environment, use this command -

Creating it once and using it wherever needed is a good idea. Add this in your styles.xml:

<style name="Divider">
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">1dp</item>
    <item name="android:background">?android:attr/listDivider</item>
</style>

and add this in your xml code, where a line divider is needed:

<View style="@style/Divider"/>

Make sure you import csv file using Pandas

import pandas as pd

condition = pd.isnull(data[i][j])

I just checked for a space in contains to check if the string has 2 or more words.

string d = "You hit someone for 50 damage";
string a = "damage";
string b = "someone";
string c = "you";

bool a = ?(d.contains(" ")):true:false;

if(a)
{
 Console.WriteLine(" " + d);
}

Console.Read();

Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want

x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)

WORD.C <- function(WORDS){
  require(wordcloud)

  L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))

  # Takes a dataframe and the text you want to display
  FUN <- function(X, text){
    windows() 
    wordcloud(X[, 1], X[, 2], min.freq=1)
    mtext(text, 3, padj=-4.5, col="red")  #what I'm trying that isn't working
  }

  # Now creates the sequence 1,...,length(L2)
  # Loops over that and then create an anonymous function
  # to send in the information you want to use.
  lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})

  # Since you asked about loops
  # you could use i in seq_along(L2) 
  # instead of 1:length(L2) if you wanted to
  #for(i in 1:length(L2)){
  #  FUN(L2[[i]], names(L2)[i])
  #}
}

WORD.C(list.xy)

Just make a rule for each case:

<div id="homePage" ng-class="{ 'center': page.isSelected(1) , 'left': !page.isSelected(1)  }">

Or use the ternary operator:

<div id="homePage" ng-class="page.isSelected(1) ? 'center' : 'left'">

Access-Control-Allow-Headers does not allow * as accepted value, see the Mozilla Documentation here.

Instead of the asterisk, you should send the accepted headers (first X-Requested-With as the error says).

AJAX is a technique to do an XMLHttpRequest (out of band Http request) from a web page to the server and send/retrieve data to be used on the web page. AJAX stands for Asynchronous Javascript And XML. It uses javascript to construct an XMLHttpRequest, typically using different techniques on various browsers.

jQuery (website) is a javascript framework that makes working with the DOM easier by building lots of high level functionality that can be used to search and interact with the DOM. Part of the functionality of jQuery implements a high-level interface to do AJAX requests. jQuery implements this interface abstractly, shielding the developer from the complexity of multi-browser support in making the request.

For those who are having trouble indenting phpstorm here I have a tip and I hope they help ...

First you have to go to file-> settings-> keymap-> select-> windows.

If they are on the windows machine. If you are on mac and choose macos.

Did you import the packages for the file reading stuff.

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

also here

cfiltering(numberOfUsers, numberOfMovies);

Are you trying to create an object or calling a method?

also another thing:

user_movie_matrix[userNo][movieNo]=rating;

you are assigning a value to a member of an instance as if it was a static variable also remove the Th in

private int user_movie_matrix[][];Th

Hope this helps.

That's because timer is a local variable to your function.

Try creating it outside of the function.
