(The above answers explained the reason quite clearly, but seems not totally clear about the size of padding, so, I will add an answer according to what I learned from The Lost Art of Structure Packing, it has evolved to not limit to C, but also applicable to Go, Rust.)

Memory align (for struct)

Rules:

• Before each individual member, there will be padding so that to make it start at an address that is divisible by its size.
  e.g on 64 bit system,int should start at address divisible by 4, and long by 8, short by 2.
• char and char[] are special, could be any memory address, so they don't need padding before them.
• For struct, other than the alignment need for each individual member, the size of whole struct itself will be aligned to a size divisible by size of largest individual member, by padding at end.
  e.g if struct's largest member is long then divisible by 8, int then by 4, short then by 2.

Order of member:

• The order of member might affect actual size of struct, so take that in mind. e.g the stu_c and stu_d from example below have the same members, but in different order, and result in different size for the 2 structs.

Address in memory (for struct)

Rules:

• 64 bit system
  Struct address starts from (n * 16) bytes. (You can see in the example below, all printed hex addresses of structs end with 0.)
  Reason: the possible largest individual struct member is 16 bytes (long double).
• (Update) If a struct only contains a char as member, its address could start at any address.

Empty space:

• Empty space between 2 structs could be used by non-struct variables that could fit in.
  e.g in test_struct_address() below, the variable x resides between adjacent struct g and h.
  No matter whether x is declared, h's address won't change, x just reused the empty space that g wasted.
  Similar case for y.

Example

(for 64 bit system)

memory_align.c:

/**
 * Memory align & padding - for struct.
 * compile: gcc memory_align.c
 * execute: ./a.out
 */ 
#include <stdio.h>

// size is 8, 4 + 1, then round to multiple of 4 (int's size),
struct stu_a {
    int i;
    char c;
};

// size is 16, 8 + 1, then round to multiple of 8 (long's size),
struct stu_b {
    long l;
    char c;
};

// size is 24, l need padding by 4 before it, then round to multiple of 8 (long's size),
struct stu_c {
    int i;
    long l;
    char c;
};

// size is 16, 8 + 4 + 1, then round to multiple of 8 (long's size),
struct stu_d {
    long l;
    int i;
    char c;
};

// size is 16, 8 + 4 + 1, then round to multiple of 8 (double's size),
struct stu_e {
    double d;
    int i;
    char c;
};

// size is 24, d need align to 8, then round to multiple of 8 (double's size),
struct stu_f {
    int i;
    double d;
    char c;
};

// size is 4,
struct stu_g {
    int i;
};

// size is 8,
struct stu_h {
    long l;
};

// test - padding within a single struct,
int test_struct_padding() {
    printf("%s: %ld\n", "stu_a", sizeof(struct stu_a));
    printf("%s: %ld\n", "stu_b", sizeof(struct stu_b));
    printf("%s: %ld\n", "stu_c", sizeof(struct stu_c));
    printf("%s: %ld\n", "stu_d", sizeof(struct stu_d));
    printf("%s: %ld\n", "stu_e", sizeof(struct stu_e));
    printf("%s: %ld\n", "stu_f", sizeof(struct stu_f));

    printf("%s: %ld\n", "stu_g", sizeof(struct stu_g));
    printf("%s: %ld\n", "stu_h", sizeof(struct stu_h));

    return 0;
}

// test - address of struct,
int test_struct_address() {
    printf("%s: %ld\n", "stu_g", sizeof(struct stu_g));
    printf("%s: %ld\n", "stu_h", sizeof(struct stu_h));
    printf("%s: %ld\n", "stu_f", sizeof(struct stu_f));

    struct stu_g g;
    struct stu_h h;
    struct stu_f f1;
    struct stu_f f2;
    int x = 1;
    long y = 1;

    printf("address of %s: %p\n", "g", &g);
    printf("address of %s: %p\n", "h", &h);
    printf("address of %s: %p\n", "f1", &f1);
    printf("address of %s: %p\n", "f2", &f2);
    printf("address of %s: %p\n", "x", &x);
    printf("address of %s: %p\n", "y", &y);

    // g is only 4 bytes itself, but distance to next struct is 16 bytes(on 64 bit system) or 8 bytes(on 32 bit system),
    printf("space between %s and %s: %ld\n", "g", "h", (long)(&h) - (long)(&g));

    // h is only 8 bytes itself, but distance to next struct is 16 bytes(on 64 bit system) or 8 bytes(on 32 bit system),
    printf("space between %s and %s: %ld\n", "h", "f1", (long)(&f1) - (long)(&h));

    // f1 is only 24 bytes itself, but distance to next struct is 32 bytes(on 64 bit system) or 24 bytes(on 32 bit system),
    printf("space between %s and %s: %ld\n", "f1", "f2", (long)(&f2) - (long)(&f1));

    // x is not a struct, and it reuse those empty space between struts, which exists due to padding, e.g between g & h,
    printf("space between %s and %s: %ld\n", "x", "f2", (long)(&x) - (long)(&f2));
    printf("space between %s and %s: %ld\n", "g", "x", (long)(&x) - (long)(&g));

    // y is not a struct, and it reuse those empty space between struts, which exists due to padding, e.g between h & f1,
    printf("space between %s and %s: %ld\n", "x", "y", (long)(&y) - (long)(&x));
    printf("space between %s and %s: %ld\n", "h", "y", (long)(&y) - (long)(&h));

    return 0;
}

int main(int argc, char * argv[]) {
    test_struct_padding();
    // test_struct_address();

    return 0;
}

Execution result - test_struct_padding():

stu_a: 8
stu_b: 16
stu_c: 24
stu_d: 16
stu_e: 16
stu_f: 24
stu_g: 4
stu_h: 8

Execution result - test_struct_address():

stu_g: 4
stu_h: 8
stu_f: 24
address of g: 0x7fffd63a95d0  // struct variable - address dividable by 16,
address of h: 0x7fffd63a95e0  // struct variable - address dividable by 16,
address of f1: 0x7fffd63a95f0 // struct variable - address dividable by 16,
address of f2: 0x7fffd63a9610 // struct variable - address dividable by 16,
address of x: 0x7fffd63a95dc  // non-struct variable - resides within the empty space between struct variable g & h.
address of y: 0x7fffd63a95e8  // non-struct variable - resides within the empty space between struct variable h & f1.
space between g and h: 16
space between h and f1: 16
space between f1 and f2: 32
space between x and f2: -52
space between g and x: 12
space between x and y: 12
space between h and y: 8

Thus address start for each variable is g:d0 x:dc h:e0 y:e8

I believe Angular 6 has the BehaviorSubject object. My sample below is done using Angular 8 and will hopefully work for Angular 6 as well.

This method is a more "reactive" approach to the problem, and assumes you are using and are well versed in rxjs.

Assuming you are using an Observable in your parent component, the component that is used in your routing definition, then you should be able to just pulse the data stream pretty easily.

My example also assumes you are using a view model in your component like so...

vm$: Observable<IViewModel>;

And in the HTML like so...

<div *ngIf="(vm$ | async) as vm">

In your component file, add a BehaviorSubject instance...

private refreshBs: BehaviorSubject<number> = new BehaviorSubject<number>(0);

Then also add an action that can be invoked by a UI element...

  refresh() {
    this.refreshBs.next(1);
  }

Here's the UI snippet, a Material Bootstrap button...

<button mdbBtn color="primary" class="ml-1 waves-dark" type="button" outline="true"
                    (click)="refresh()" mdbWavesEffect>Refresh</button>

Then, in your ngOnIt function do something like this, keep in mind that my example is simplified a bit so that I don't have to provide a lot of code...

  ngOnInit() {

    this.vm$ = this.refreshBs.asObservable().pipe(
      switchMap(v => this.route.queryParamMap),
      map(qpm => qpm.get("value")),
      tap(v => console.log(`query param value: "${v}"`)),

      // simulate data load
      switchMap(v => of(v).pipe(
        delay(500),
        map(v => ({ items: [] }))
      )),
      
      catchError(e => of({ items: [], error: e }))
    );
    
  }

The basename does that, removes the path. It will also remove the suffix if given and if it matches the suffix of the file but you would need to know the suffix to give to the command. Otherwise you can use mv and figure out what the new name should be some other way.

There is this, which I credit to this blog:

@media only screen and (min-device-width: 560px) and (max-device-width: 1136px) and (-webkit-min-device-pixel-ratio: 2) {
    /* iPhone 5 only */
}

Keep in mind it reacts the iPhone 5, not to the particular iOS version installed on said device.

To merge with your existing version, you should be able to comma-delimit them:

@media only screen and (max-device-width: 480px), only screen and (min-device-width: 560px) and (max-device-width: 1136px) and (-webkit-min-device-pixel-ratio: 2) {
    /* iPhone only */
}

NB: I haven't tested the above code, but I've tested comma-delimited @media queries before, and they work just fine.

Note that the above may hit some other devices which share similar ratios, such as the Galaxy Nexus. Here is an additional method which will target only devices which have one dimension of 640px (560px due to some weird display-pixel anomalies) and one of between 960px (iPhone <5) and 1136px (iPhone 5).

@media
    only screen and (max-device-width: 1136px) and (min-device-width: 960px) and (max-device-height: 640px) and (min-device-height: 560px),
    only screen and (max-device-height: 1136px) and (min-device-height: 960px) and (max-device-width: 640px) and (min-device-width: 560px) {
    /* iPhone only */
}

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

   VIS_ROW_ID    NUMBER;

First Of All Firebase.ServerValue.TIMESTAMP is not working anymore for me.

So for adding timestamp you have to use Firebase.database.ServerValue.TIMESTAMP

And the timestamp is in long millisecond format.To convert millisecond to simple dateformat .

Ex- dd/MM/yy HH:mm:ss

You can use the following code in java:

To get the timestamp value in string from the firebase database

String x = dataSnapshot.getValue (String.class);

The data is in string now. You can convert the string to long

long milliSeconds= Long.parseLong(x);

Then create SimpleDateFormat

SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yy HH:mm:ss");

Now convert your millisecond timestamp to ur sdf format

String dateAsString = sdf.format (milliSeconds);

After that you can parse it to ur Date variable

 date = sdf.parse (dateAsString);

Building on the other answers, I wanted to share an example of using the while loop construct to achieve a do-while behaviour. By using a simple boolean variable in the while condition (initialized to TRUE), and then checking our actual condition later in the if statement. One could also use a break keyword instead of the continue <- FALSE inside the if statement (probably more efficient).

  df <- data.frame(X=c(), R=c())  
  x <- x0
  continue <- TRUE

  while(continue)
  {
    xi <- (11 * x) %% 16
    df <- rbind(df, data.frame(X=x, R=xi))
    x <- xi

    if(xi == x0)
    {
      continue <- FALSE
    }
  }

No need to use a form at all unless you want to post to the action. An input button (not submit) will do the trick.

  <input type="button"
         value="Go Somewhere Else"
         onclick="location.href='<%: Url.Action("Action", "Controller") %>'" />

Thanking Daniel Jimenez for his perfect solution to fetch column names alone from my csv, I extend his solution to use DictReader so we can iterate over the rows using column names as indexes. Thanks Jimenez.

with open('myfile.csv') as csvfile:

    rest = []
    with open("myfile.csv", "rb") as f:
        reader = csv.reader(f)
        i = reader.next()
        i=i[1:]
        re=csv.DictReader(csvfile)
        for row in re:
            for x in i:
                print row[x]

The newest version of the Android emulator can be run with Hyper-V instead of Intel HAXM on the Windows 10 1804:

https://blogs.msdn.microsoft.com/visualstudio/2018/05/08/hyper-v-android-emulator-support/

Short version:

• install Windows Hypervisor Platform feature
• Update to Android Emulator 27.2.7 or above
• put WindowsHypervisorPlatform = on into C:\Users\.android\advancedFeatures.ini or start emulator or command line with -feature WindowsHypervisorPlatform

This is yet another reason to use Joda Time

new DateMidnight(2010, 3, 5)

DateMidnight is now deprecated but the same effect can be achieved with Joda Time DateTime

DateTime dt = new DateTime(2010, 3, 5, 0, 0);

Look for "Windows x86", it's the 32 bit version.

Running PHP as a CGI means that you basically tell your web server the location of the PHP executable file, and the server runs that executable

whereas

PHP FastCGI Process Manager (PHP-FPM) is an alternative FastCGI daemon for PHP that allows a website to handle strenuous loads. PHP-FPM maintains pools (workers that can respond to PHP requests) to accomplish this. PHP-FPM is faster than traditional CGI-based methods, such as SUPHP, for multi-user PHP environments

However, there are pros and cons to both and one should choose as per their specific use case.

I found info on this link for fastcgi vs fpm quite helpful in choosing which handler to use in my scenario.

Remember that your suggestions makes it difficult for clients to communicate with the server. They need to understand your innovative solution and encrypt the data accordingly, this model is not so good for public API (unless you are amazon\yahoo\google..).

Anyways, if you must encrypt the body content I would suggest you to check out existing standards and solutions like:

XML encryption (W3C standard)

XML Security

Encode the response content with a common enum that allows the client to switch on it and fork logic accordingly. I'm not sure how your client would distinguish the difference between a "data not found" 404 and a "web resource not found" 404? You don;t want someone to browse to userZ/9 and have the client wonder off as if the request was valid but there was no data returned.

Ross, you can use Arrays.copyof() or Arrays.copyOfRange() too.

Integer[] integerArray = Arrays.copyOf(a, a.length, Integer[].class);
Integer[] integerArray = Arrays.copyOfRange(a, 0, a.length, Integer[].class);

Here the reason to hitting an ClassCastException is you can't treat an array of Integer as an array of Object. Integer[] is a subtype of Object[] but Object[] is not a Integer[].

And the following also will not give an ClassCastException.

Object[] a = new Integer[1];
Integer b=1;
a[0]=b;
Integer[] c = (Integer[]) a;

As of now, with Revision 26.1.3 of the android emulator, it is finally possible on the image v8 of the API 25. If the emulator was created before you upgrade to the latest API 25 image, you need to wipe data or simply delete and recreate your image if you prefer.

Added support for Wi-Fi in some system images (currently only API level 25). An access point called "AndroidWifi" is available and Android automatically connects to it. Wi-Fi support can be disabled by running the emulator with the command line parameter -feature -Wifi.

from https://developer.android.com/studio/releases/emulator.html#26-1-3

Another way to reset the values (for multiple selected elements) could be this:

$("selector").each(function(){

    /*Perform any check and validation if needed for each item */

    /*Use "this" to handle the element in javascript or "$(this)" to handle the element with jquery */

    this.selectedIndex=0;

});

There is a more effective way of generating an intersect, by using UNION ALL and GROUP BY. Performances are twice better according to my tests on large datasets.

Example:

SELECT t1.value from (
  (SELECT DISTINCT value FROM table_a)
  UNION ALL 
  (SELECT DISTINCT value FROM table_b)
) AS t1 GROUP BY value HAVING count(*) >= 2;

It is more effective, because with the INNER JOIN solution, MySQL will look up for the results of the first query, then for each row, look up for the result in the second query. With the UNION ALL-GROUP BY solution, it will query results of the first query, results of the second query, then group the results all together at once.

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

Update (Recommended):

On latest Flutter version, you should use:

AppBar(
  backwardsCompatibility: false,
  systemOverlayStyle: SystemUiOverlayStyle(statusBarColor: Colors.orange),
)

Only Android (more flexibility):

import 'package:flutter/services.dart';

void main() {
  SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
    systemNavigationBarColor: Colors.blue, // navigation bar color
    statusBarColor: Colors.pink, // status bar color
  ));
}

Both iOS and Android:

appBar: AppBar(
  backgroundColor: Colors.red, // status bar color
  brightness: Brightness.light, // status bar brightness
)

If you actually want to add/remove items from an array, may I suggest a List instead?

String[] firstArray = {"test1","","test2","test4",""};
ArrayList<String> list = new ArrayList<String>();
for (String s : firstArray)
    if (!s.equals(""))
        list.add(s);

Then, if you really need to put that back into an array:

firstArray = list.toArray(new String[list.size()]);

I'm sure you can use RAISERROR ... WITH NOWAIT

If you use severity 10 it's not an error. This also provides some handy formatting eg %s, %i and you can use state too to track where you are.

Extend UIScrollView to add a scrollToBottom method:

extension UIScrollView {
    func scrollToBottom(animated:Bool) {
        let offset = self.contentSize.height - self.visibleSize.height
        if offset > self.contentOffset.y {
            self.setContentOffset(CGPoint(x: 0, y: offset), animated: animated)
        }
    }
}

If you need to do a QQ plot of one sample vs. another, statsmodels includes qqplot_2samples(). Like Ricky Robinson in a comment above, this is what I think of as a QQ plot vs a probability plot which is a sample against a theoretical distribution.

For anyone who comes across this in the future, I want to share this gem from the PHP docs, posted by an anonymous user:

There seems to be some confusion here. The distinction between pointers and references is not particularly helpful. The behavior in some of the "comprehensive" examples already posted can be explained in simpler unifying terms. Hayley's code, for example, is doing EXACTLY what you should expect it should. (Using >= 5.3)

First principle: A pointer stores a memory address to access an object. Any time an object is assigned, a pointer is generated. (I haven't delved TOO deeply into the Zend engine yet, but as far as I can see, this applies)

2nd principle, and source of the most confusion: Passing a variable to a function is done by default as a value pass, ie, you are working with a copy. "But objects are passed by reference!" A common misconception both here and in the Java world. I never said a copy OF WHAT. The default passing is done by value. Always. WHAT is being copied and passed, however, is the pointer. When using the "->", you will of course be accessing the same internals as the original variable in the caller function. Just using "=" will only play with copies.

3rd principle: "&" automatically and permanently sets another variable name/pointer to the same memory address as something else until you decouple them. It is correct to use the term "alias" here. Think of it as joining two pointers at the hip until forcibly separated with "unset()". This functionality exists both in the same scope and when an argument is passed to a function. Often the passed argument is called a "reference," due to certain distinctions between "passing by value" and "passing by reference" that were clearer in C and C++.

Just remember: pointers to objects, not objects themselves, are passed to functions. These pointers are COPIES of the original unless you use "&" in your parameter list to actually pass the originals. Only when you dig into the internals of an object will the originals change.

And here's the example they provide:

<?php

//The two are meant to be the same
$a = "Clark Kent"; //a==Clark Kent
$b = &$a; //The two will now share the same fate.

$b="Superman"; // $a=="Superman" too.

I wrote an extensive, detailed blog post on this subject for JavaScript, but I believe it applies equally well to PHP, C++, and any other language where people seem to be confused about pass by value vs. pass by reference.

Clearly, PHP, like C++, is a language that does support pass by reference. By default, objects are passed by value. When working with variables that store objects, it helps to see those variables as pointers (because that is fundamentally what they are, at the assembly level). If you pass a pointer by value, you can still "trace" the pointer and modify the properties of the object being pointed to. What you cannot do is have it point to a different object. Only if you explicitly declare a parameter as being passed by reference will you be able to do that.

Try something like this:

Dim windowsShell
Dim regValue
Set windowsShell = CreateObject("WScript.Shell")
regValue = windowsShell.RegRead("someRegKey")

If this was based on roles you could use the multiview panel but not sure if you could do the same against a property of the record.

However, you could do this via code. In your rowdatabound event you can hide or show the button in it.

import time
import sys


def update_pct(w_str):
    w_str = str(w_str)
    sys.stdout.write("\b" * len(w_str))
    sys.stdout.write(" " * len(w_str))
    sys.stdout.write("\b" * len(w_str))
    sys.stdout.write(w_str)
    sys.stdout.flush()

for pct in range(0, 101):
    update_pct("{n}%".format(n=str(pct)))
    time.sleep(0.1)

\b will move the location of the cursor back one space
So we move it back all the way to the beginning of the line
We then write spaces to clear the current line - as we write spaces the cursor moves forward/right by one
So then we have to move the cursor back at the beginning of the line before we write our new data

Tested on Windows cmd using Python 2.7

Convert.ToDouble(x) can also have a second parameter that indicates the CultureInfo and when you set it to System.Globalization.CultureInfo InvariantCulture the result will allways be the same.

I know I'm late to the party on this, but thought you might find this variant useful, as this one also allows you to use descriptive strings rather than enumeration constants in the drop down. To do this, decorate each enumeration entry with a [System.ComponentModel.Description] attribute.

For example:

public enum TestEnum
{
  [Description("Full test")]
  FullTest,

  [Description("Incomplete or partial test")]
  PartialTest,

  [Description("No test performed")]
  None
}

Here is my code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using System.Web.Mvc.Html;
using System.Reflection;
using System.ComponentModel;
using System.Linq.Expressions;

 ...

 private static Type GetNonNullableModelType(ModelMetadata modelMetadata)
    {
        Type realModelType = modelMetadata.ModelType;

        Type underlyingType = Nullable.GetUnderlyingType(realModelType);
        if (underlyingType != null)
        {
            realModelType = underlyingType;
        }
        return realModelType;
    }

    private static readonly SelectListItem[] SingleEmptyItem = new[] { new SelectListItem { Text = "", Value = "" } };

    public static string GetEnumDescription<TEnum>(TEnum value)
    {
        FieldInfo fi = value.GetType().GetField(value.ToString());

        DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(typeof(DescriptionAttribute), false);

        if ((attributes != null) && (attributes.Length > 0))
            return attributes[0].Description;
        else
            return value.ToString();
    }

    public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression)
    {
        return EnumDropDownListFor(htmlHelper, expression, null);
    }

    public static MvcHtmlString EnumDropDownListFor<TModel, TEnum>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TEnum>> expression, object htmlAttributes)
    {
        ModelMetadata metadata = ModelMetadata.FromLambdaExpression(expression, htmlHelper.ViewData);
        Type enumType = GetNonNullableModelType(metadata);
        IEnumerable<TEnum> values = Enum.GetValues(enumType).Cast<TEnum>();

        IEnumerable<SelectListItem> items = from value in values
            select new SelectListItem
            {
                Text = GetEnumDescription(value),
                Value = value.ToString(),
                Selected = value.Equals(metadata.Model)
            };

        // If the enum is nullable, add an 'empty' item to the collection
        if (metadata.IsNullableValueType)
            items = SingleEmptyItem.Concat(items);

        return htmlHelper.DropDownListFor(expression, items, htmlAttributes);
    }

You can then do this in your view:

@Html.EnumDropDownListFor(model => model.MyEnumProperty)

Hope this helps you!

**EDIT 2014-JAN-23: Microsoft have just released MVC 5.1, which now has an EnumDropDownListFor feature. Sadly it does not appear to respect the [Description] attribute so the code above still stands.See Enum section in Microsoft's release notes for MVC 5.1.

Update: It does support the Display attribute [Display(Name = "Sample")] though, so one can use that.

[Update - just noticed this, and the code looks like an extended version of the code here: https://blogs.msdn.microsoft.com/stuartleeks/2010/05/21/asp-net-mvc-creating-a-dropdownlist-helper-for-enums/, with a couple of additions. If so, attribution would seem fair ;-)]

With array_flip() it could look like this:

$flipped = array_flip($opts);
$flipped[$newValue] = 1;
$opts = array_keys($flipped);

With array_unique() - like this:

$opts[] = $newValue;
$opts = array_values(array_unique($opts));

Notice that array_values(...) — you need it if you're exporting array to JavaScript in JSON form. array_unique() alone would simply unset duplicate keys, without rebuilding the remaining elements'. So, after converting to JSON this would produce object, instead of array.

>>> json_encode(array_unique(['a','b','b','c']))
=> "{"0":"a","1":"b","3":"c"}"

>>> json_encode(array_values(array_unique(['a','b','b','c'])))
=> "["a","b","c"]"

Just thought I'd add that I've improved Mud's SimplerAES by adding a random IV that's passed back inside the encrypted string. This improves the encryption as encrypting the same string will result in a different output each time.

public class StringEncryption
{
    private readonly Random random;
    private readonly byte[] key;
    private readonly RijndaelManaged rm;
    private readonly UTF8Encoding encoder;

    public StringEncryption()
    {
        this.random = new Random();
        this.rm = new RijndaelManaged();
        this.encoder = new UTF8Encoding();
        this.key = Convert.FromBase64String("Your+Secret+Static+Encryption+Key+Goes+Here=");
    }

    public string Encrypt(string unencrypted)
    {
        var vector = new byte[16];
        this.random.NextBytes(vector);
        var cryptogram = vector.Concat(this.Encrypt(this.encoder.GetBytes(unencrypted), vector));
        return Convert.ToBase64String(cryptogram.ToArray());
    }

    public string Decrypt(string encrypted)
    {
        var cryptogram = Convert.FromBase64String(encrypted);
        if (cryptogram.Length < 17)
        {
            throw new ArgumentException("Not a valid encrypted string", "encrypted");
        }

        var vector = cryptogram.Take(16).ToArray();
        var buffer = cryptogram.Skip(16).ToArray();
        return this.encoder.GetString(this.Decrypt(buffer, vector));
    }

    private byte[] Encrypt(byte[] buffer, byte[] vector)
    {
        var encryptor = this.rm.CreateEncryptor(this.key, vector);
        return this.Transform(buffer, encryptor);
    }

    private byte[] Decrypt(byte[] buffer, byte[] vector)
    {
        var decryptor = this.rm.CreateDecryptor(this.key, vector);
        return this.Transform(buffer, decryptor);
    }

    private byte[] Transform(byte[] buffer, ICryptoTransform transform)
    {
        var stream = new MemoryStream();
        using (var cs = new CryptoStream(stream, transform, CryptoStreamMode.Write))
        {
            cs.Write(buffer, 0, buffer.Length);
        }

        return stream.ToArray();
    }
}

And bonus unit test

[Test]
public void EncryptDecrypt()
{
    // Arrange
    var subject = new StringEncryption();
    var originalString = "Testing123!£$";

    // Act
    var encryptedString1 = subject.Encrypt(originalString);
    var encryptedString2 = subject.Encrypt(originalString);
    var decryptedString1 = subject.Decrypt(encryptedString1);
    var decryptedString2 = subject.Decrypt(encryptedString2);

    // Assert
    Assert.AreEqual(originalString, decryptedString1, "Decrypted string should match original string");
    Assert.AreEqual(originalString, decryptedString2, "Decrypted string should match original string");
    Assert.AreNotEqual(originalString, encryptedString1, "Encrypted string should not match original string");
    Assert.AreNotEqual(encryptedString1, encryptedString2, "String should never be encrypted the same twice");
}

I've done a bit of development for S3 and I have not found a simple way to download a whole bucket.

If you want to code in Java the jets3t lib is easy to use to create a list of buckets and iterate over that list to download them.

First, get a public private key set from the AWS management consule so you can create an S3service object:

AWSCredentials awsCredentials = new AWSCredentials(YourAccessKey, YourAwsSecretKey);
s3Service = new RestS3Service(awsCredentials);

Then, get an array of your buckets objects:

S3Object[] objects = s3Service.listObjects(YourBucketNameString);

Finally, iterate over that array to download the objects one at a time with:

S3Object obj = s3Service.getObject(bucket, fileName);
            file = obj.getDataInputStream();

I put the connection code in a threadsafe singleton. The necessary try/catch syntax has been omitted for obvious reasons.

If you'd rather code in Python you could use Boto instead.

After looking around BucketExplorer, "Downloading the whole bucket" may do what you want.

This will definately work for you.

JSch is a pure Java implementation of SSH2 that helps you run commands on remote machines. You can find it here, and there are some examples here.

You can use exec.java.

A request to list "Number of employees in each department" or "Display how many people work in each department" is the same as "For each department, list the number of employees", this must include departments with no employees. In the sample database, Operations has 0 employees. So a LEFT OUTER JOIN should be used.

SELECT dept.name, COUNT(emp.empno) AS count
FROM dept
LEFT OUTER JOIN emp ON emp.deptno = dept.deptno
GROUP BY dept.name;

workmad3 is apparently out of date, at least for current gpg, as the --allow-secret-key-import is now obsolete and does nothing.

What happened to me was that I failed to export properly. Just doing gpg --export is not adequate, as it only exports the public keys. When exporting keys, you have to do

gpg --export-secret-keys >keyfile

In a GET request, you pass parameters as part of the query string.

string url = "http://somesite.com?var=12345";

You should add a __eq__ and a __hash__ method to your Data class, it could check if the __dict__ attributes are equal (same properties) and then if their values are equal, too.

If you did that, you can use

test = Data()
test.n = 5

found = test in myList

The in keyword checks if test is in myList.

If you only want to a a n property in Data you could use:

class Data(object):
    __slots__ = ['n']
    def __init__(self, n):
        self.n = n
    def __eq__(self, other):
        if not isinstance(other, Data):
            return False
        if self.n != other.n:
            return False
        return True
    def __hash__(self):
        return self.n

    myList = [ Data(1), Data(2), Data(3) ]
    Data(2) in myList  #==> True
    Data(5) in myList  #==> False

Here is a complete example for navigating valid URL on a new tab with focused.

HTML:

<div class="panel">
  <p>
    Enter Url: 
    <input type="text" id="txturl" name="txturl" size="30" class="weburl" />
    &nbsp;&nbsp;    
    <input type="button" id="btnopen"  value="Open Url in New Tab" onclick="openURL();"/>
  </p>
</div>

CSS:

.panel{
  font-size:14px;
}
.panel input{
  border:1px solid #333;
}

JAVASCRIPT:

function isValidURL(url) {
    var RegExp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/;

    if (RegExp.test(url)) {
        return true;
    } else {
        return false;
    }
}

function openURL() {
    var url = document.getElementById("txturl").value.trim();
    if (isValidURL(url)) {
        var myWindow = window.open(url, '_blank');
        myWindow.focus();
        document.getElementById("txturl").value = '';
    } else {
        alert("Please enter valid URL..!");
        return false;
    }
}

I have also created a bin with the solution on http://codebins.com/codes/home/4ldqpbw

Customize com.facebook.widget.LoginButton

step:1 Creating a Framelayout.

step:2 To set com.facebook.widget.LoginButton

step:3 To set Textview with customizable.

    android:layout_height="wrap_content"
    >
    <com.facebook.widget.LoginButton
        android:id="@+id/fbLogin"

MUST REMEMBER

1> com.facebook.widget.LoginButton & TextView Height/Width Same

2> 1st declate com.facebook.widget.LoginButton then TextView

3> To perform login/logout using TextView's Click-Listener

Maybe it is easier to convert the Date into the actual integer 20110506105524 and then convert this into a string:

function printDate() {
    var temp = new Date();
    var dateInt =
        ((((temp.getFullYear() * 100 + 
            temp.getMonth() + 1) * 100 + 
           temp.getDate()) * 100 +
          temp.getHours()) * 100 + 
         temp.getMinutes()) * 100 + 
        temp.getSeconds();

    debug ( '' + dateInt );  // convert to String
}

When temp.getFullYear() < 1000 the result will be one (or more) digits shorter.

Caution: this wont work with millisecond precision (i.e. 17 digits) since Number.MAX_SAFE_INTEGER is 9007199254740991 which is only 16 digits.

I'd suggest doing something similar to:

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = parent.getElementsByClassName('sub');
        if (sub[0].style.display == 'inline'){
            sub[0].style.display = 'none';
        }
        else {
            sub[0].style.display = 'inline';
        }
    }
}

document.getElementById('cat').onclick = function(){
    show_sub(this.id);
};????

JS Fiddle demo.

Though the above relies on the use of a class rather than a name attribute equal to sub.

As to why your original version "didn't work" (not, I must add, a particularly useful description of the problem), all I can suggest is that, in Chromium, the JavaScript console reported that:

Uncaught TypeError: Object # has no method 'getElementsByName'.

One approach to working around the older-IE family's limitations is to use a custom function to emulate getElementsByClassName(), albeit crudely:

function eBCN(elem,classN){
    if (!elem || !classN){
        return false;
    }
    else {
        var children = elem.childNodes;
        for (var i=0,len=children.length;i<len;i++){
            if (children[i].nodeType == 1
                &&
                children[i].className == classN){
                    var sub = children[i];
            }
        }
        return sub;
    }
}

function show_sub(cat) {
    if (!cat) {
        return false;
    }
    else if (document.getElementById(cat)) {
        var parent = document.getElementById(cat),
            sub = eBCN(parent,'sub');
        if (sub.style.display == 'inline'){
            sub.style.display = 'none';
        }
        else {
            sub.style.display = 'inline';
        }
    }
}

var D = document,
    listElems = D.getElementsByTagName('li');
for (var i=0,len=listElems.length;i<len;i++){
    listElems[i].onclick = function(){
        show_sub(this.id);
    };
}?

You can use the CSS property background-size and set it to cover or contain, depending your preference. Cover will cover the window entirely, while contain will make one side fit the window thus not covering the entire page (unless the aspect ratio of the screen is equal to the image).

Please note that this is a CSS3 property. In older browsers, this property is ignored. Alternatively, you can use javascript to change the CSS settings depending on the window size, but this isn't preferred.

body {
    background-image: url(image.jpg); /* image */
    background-position: center;      /* center the image */
    background-size: cover;           /* cover the entire window */
}

assuming chrome is his default browser: start http://url.site.you.com/path/to/joke should open that url in his browser.

Here is an efficient solution for fast creation of a randomized array. After randomization you can simply pick the n-th element e of the array, increment n and return e. This solution has O(1) for getting a random number and O(n) for initialization, but as a tradeoff requires a good amount of memory if n gets large enough.

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

Firebase.remove() like probably most Firebase methods is asynchronous, thus you have to listen to events to know when something happened:

parent = ref.parent()
parent.on('child_removed', function (snapshot) {
    // removed!
})
ref.remove()

According to Firebase docs it should work even if you lose network connection. If you want to know when the change has been actually synchronized with Firebase servers, you can pass a callback function to Firebase.remove method:

ref.remove(function (error) {
    if (!error) {
        // removed!
    }
}

Nowadays it is even easier to clone the machine with EBS-backed instances released a while ago. This is how we do it in BitNami Cloud Hosting. Basically you just take a snapshot of the instance which can be used later to launch a new server. You can do it either using AWS console (saving the EBS-backed instance as AWS AMI) or using the EC2 API tools:

• create a snapshot with ec2-create-snapshot
• and then launch an instance from a snapshot

Cloning the instance is nothing else but creating the backup and then launching a new server based on that. You can find bunch of articles out there describing this problem, try to find the info about "how to ..." backup or resize the whole EC2 instance, for example this blog is a really good place to start: alestic.com

Moreover, you can still use the "ordinary" if syntax and conflate it into one line with a colon.

if i > 3: print("We are done.")

or

field_plural = None
if field_plural is not None: print("insert into testtable(plural) '{0}'".format(field_plural)) 

You can run below commands. I believe this is what you want!

Note: Make sure the port 8080 is open. If not, kill the process that is using 8080 port using sudo kill -9 $(sudo lsof -t -i:8080)

 ./catalina.sh run

One can also do this with a compact version of @TomAugspurger's answer, like so:

df = df1.merge(df2, how='left', on=['Year', 'Week', 'Colour']).merge(df3[['Week', 'Colour', 'Val3']], how='left', on=['Week', 'Colour'])

Here is a link that has a performance test you can run. find() is actually about 2 times faster than children().

You need to specify the column in both expressions.

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

Both styles, with a touch of tweaking, would work.

The first method uses a Javascript Constructor, which like most things has pros and cons.

 // By convention, constructors start with an upper case letter
function MakePerson(name,age) {
  // The magic variable 'this' is set by the Javascript engine and points to a newly created object that is ours.
  this.name = name;
  this.age = age;
  this.occupation = "Hobo";
}
var jeremy = new MakePerson("Jeremy", 800);

On the other hand, your other method is called the 'Revealing Closure Pattern' if I recall correctly.

function makePerson(name2, age2) {
  var name = name2;
  var age = age2;

  return {
    name: name,
    age: age
  };
}

Simple: active the accordion to a class, and then create divs with this, like multiples instances of accordion.

Like this:

JS

$(function() {
    $( ".accordion" ).accordion({

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

I don't know if this will help, but here's the SWT FAQ question How do I use Mozilla as the Browser's underlying renderer?

Edit: Having researched this further, it sounds like this isn't possible in Eclipse 3.4, but may be slated for a later release.

Couldn't your query just be written as:

SELECT u1.name as UserName from Message m1, User u1 
  WHERE u1.uid = m1.UserFromID GROUP BY u1.name HAVING count(m1.UserFromId)>3

That should also help with the known speed issues with subqueries in MySQL

You can compile your C programs with an ARM cross-compiler:

arm-linux-gnueabi-gcc -static -march=armv7-a test.c -o test

Then you can push your compiled binary file to somewhere (don't push it in to the SD card):

adb push test /data/local/tmp/test

For Select2 v4:

Use dropdownParent to attach the dropdown to the modal dialog, rather than the HTML body.

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        <select id="select2insidemodal" multiple="multiple">
          <option value="AL">Alabama</option>
            ...
          <option value="WY">Wyoming</option>
        </select>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>


<script>

$(document).ready(function() {
  $("#select2insidemodal").select2({
    dropdownParent: $("#myModal")
  });
});

</script>

This will attach the Select2 dropdown so it falls within the DOM of the modal rather than to the HTML body (the default). See https://select2.org/dropdown#dropdown-placement

The following code returns 1 if the table exists or 0 if the table does not exist.

SELECT CASE WHEN tbl_name = "name" THEN 1 ELSE 0 END FROM sqlite_master WHERE tbl_name = "name" AND type = "table"

Since Java 9

As of this version, you can use a new method Matcher::results with no args that is able to comfortably return Stream<MatchResult> where MatchResult represents the result of a match operation and offers to read matched groups and more (this class is known since Java 1.5).

String string = "Some string with 'the data I want' inside and 'another data I want'.";

Pattern pattern = Pattern.compile("'(.*?)'");
pattern.matcher(string)
       .results()                       // Stream<MatchResult>
       .map(mr -> mr.group(1))          // Stream<String> - the 1st group of each result
       .forEach(System.out::println);   // print them out (or process in other way...)

The code snippet above results in:

the data I want
another data I want

The biggest advantage is in the ease of usage when one or more results is available compared to the procedural if (matcher.find()) and while (matcher.find()) checks and processing.

datepicker in Finnish (Käännös suomeksi)

$.datepicker.regional['fi'] = {

  };

Note, that Dijkstra works even for negative weights, if the Graph has no negative cycles, i.e. cycles whose summed up weight is less than zero.

Of course one might ask, why in the example made by templatetypedef Dijkstra fails even though there are no negative cycles, infact not even cycles. That is because he is using another stop criterion, that holds the algorithm as soon as the target node is reached (or all nodes have been settled once, he did not specify that exactly). In a graph without negative weights this works fine.

If one is using the alternative stop criterion, which stops the algorithm when the priority-queue (heap) runs empty (this stop criterion was also used in the question), then dijkstra will find the correct distance even for graphs with negative weights but without negative cycles.

However, in this case, the asymptotic time bound of dijkstra for graphs without negative cycles is lost. This is because a previously settled node can be reinserted into the heap when a better distance is found due to negative weights. This property is called label correcting.

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

you need to use backslash before ". like \"

From the doc here you can see that

A character preceded by a backslash ( \ ) is an escape sequence and has special meaning to the compiler.

and " (double quote) is a escacpe sequence

When an escape sequence is encountered in a print statement, the compiler interprets it accordingly. For example, if you want to put quotes within quotes you must use the escape sequence, \", on the interior quotes. To print the sentence

She said "Hello!" to me.

you would write

System.out.println("She said \"Hello!\" to me.");

Remove the protected branch option or allow additional roles like developers or admins to allow these users experiencing this error to do merges and push.

xorWith in Lodash can be used to achieve this

let objects = [ { id: 1, username: 'fred' }, { id: 2, username: 'bill' }, { id: 2, username: 'ted' } ]
let existingObject = { id: 1, username: 'fred' };
let newObject = { id: 1729, username: 'Ramanujan' }

_.xorWith(objects, [existingObject], _.isEqual)
// returns [ { id: 2, username: 'bill' }, { id: 2, username: 'ted' } ]

_.xorWith(objects, [newObject], _.isEqual)
// returns [ { id: 1, username: 'fred' }, { id: 2, username: 'bill' }, { id: 2, username: 'ted' } ,{ id: 1729, username: 'Ramanujan' } ]

Single Property solution is:

.className {
    text-decoration: line-through red;
};

Define your color after line through property.

Hadley has a very elegant solution to do this inside data frames in his reshape package, using the function colsplit.

require(reshape)
> df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
> df
  ID FOO
1 11 a|b
2 12 b|c
3 13 x|y
> df = transform(df, FOO = colsplit(FOO, split = "\\|", names = c('a', 'b')))
> df
  ID FOO.a FOO.b
1 11     a     b
2 12     b     c
3 13     x     y

Pass by pointer is the only way you could pass "by reference" in C, so you still see it used quite a bit.

The NULL pointer is a handy convention for saying a parameter is unused or not valid, so use a pointer in that case.

References can't be updated once they're set, so use a pointer if you ever need to reassign it.

Prefer a reference in every case where there isn't a good reason not to. Make it const if you can.

Here is a sample code that includes a legend if that is of interest.

# First create an empty plot.
plot(1, type = 'n', xlim = c(xminp, xmaxp), ylim = c(0, 1), 
     xlab = "log transformed coverage", ylab = "frequency")

# Create a list of 22 colors to use for the lines.
cl <- rainbow(22)

# Now fill plot with the log transformed coverage data from the
# files one by one.
for(i in 1:length(data)) {
    lines(density(log(data[[i]]$coverage)), col = cl[i])
    plotcol[i] <- cl[i]
}
legend("topright", legend = c(list.files()), col = plotcol, lwd = 1,
       cex = 0.5)

I did like David Brown said but I got the following exception.

$exception {"There are multiple root elements. Line , position ."} System.Xml.XmlException

One solution would be to modify the XML file with a root element but that is not always necessary and for an XML stream it might not be possible either. My solution below:

var path = Path.GetFullPath(Path.Combine(Environment.CurrentDirectory, @"..\..\App_Data"));
var directoryInfo = new DirectoryInfo(path);
var fileInfos = directoryInfo.GetFiles("*.xml");

foreach (var fileInfo in fileInfos)
{
    XmlDocument doc = new XmlDocument();
    XmlReaderSettings settings = new XmlReaderSettings();
    settings.ConformanceLevel = ConformanceLevel.Fragment;

    using (XmlReader reader = XmlReader.Create(fileInfo.FullName, settings))
    {
        while (reader.Read())
        {
            if (reader.NodeType == XmlNodeType.Element)
            {
                var node = doc.ReadNode(reader);
                string json = JsonConvert.SerializeXmlNode(node);
            }
        }
    }
}

Example XML that generates the error:

<parent>
    <child>
        Text
    </child>
</parent>
<parent>
    <child>
        <grandchild>
            Text
        </grandchild>
        <grandchild>
            Text
        </grandchild>
    </child>
    <child>
        Text
    </child>
</parent>

The most voted answer is for solving this specific problem posted by OP, where the content (text) was being wrapped inside an inline-block element. Some cases may be about centering a normal element vertically inside a container, which also applied in my case, so for that all you need is:

align-self: center;

jQuery Mobile has a datepicker too. Source

Just include the following files,

  <script src="jQuery.ui.datepicker.js"></script>
  <script src="jquery.ui.datepicker.mobile.js"></script>

You can use viewtype to solve this problem, here is my demo: https://github.com/yefengfreedom/RecyclerViewWithHeaderFooterLoadingEmptyViewErrorView

1. you can define some recycler view display mode:

   public static final int MODE_DATA = 0, MODE_LOADING = 1, MODE_ERROR = 2, MODE_EMPTY = 3, MODE_HEADER_VIEW = 4, MODE_FOOTER_VIEW = 5;

2.override the getItemViewType mothod

 @Override
public int getItemViewType(int position) {
    if (mMode == RecyclerViewMode.MODE_LOADING) {
        return RecyclerViewMode.MODE_LOADING;
    }
    if (mMode == RecyclerViewMode.MODE_ERROR) {
        return RecyclerViewMode.MODE_ERROR;
    }
    if (mMode == RecyclerViewMode.MODE_EMPTY) {
        return RecyclerViewMode.MODE_EMPTY;
    }
    //check what type our position is, based on the assumption that the order is headers > items > footers
    if (position < mHeaders.size()) {
        return RecyclerViewMode.MODE_HEADER_VIEW;
    } else if (position >= mHeaders.size() + mData.size()) {
        return RecyclerViewMode.MODE_FOOTER_VIEW;
    }
    return RecyclerViewMode.MODE_DATA;
}

3.override the getItemCount method

@Override
public int getItemCount() {
    if (mMode == RecyclerViewMode.MODE_DATA) {
        return mData.size() + mHeaders.size() + mFooters.size();
    } else {
        return 1;
    }
}

4.override the onCreateViewHolder method. create view holder by viewType

@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    if (viewType == RecyclerViewMode.MODE_LOADING) {
        RecyclerView.ViewHolder loadingViewHolder = onCreateLoadingViewHolder(parent);
        loadingViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        return loadingViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_ERROR) {
        RecyclerView.ViewHolder errorViewHolder = onCreateErrorViewHolder(parent);
        errorViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        errorViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnErrorViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnErrorViewClickListener.onErrorViewClick(v);
                        }
                    }, 200);
                }
            }
        });
        return errorViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_EMPTY) {
        RecyclerView.ViewHolder emptyViewHolder = onCreateEmptyViewHolder(parent);
        emptyViewHolder.itemView.setLayoutParams(
                new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, parent.getHeight() - mToolBarHeight)
        );
        emptyViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnEmptyViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnEmptyViewClickListener.onEmptyViewClick(v);
                        }
                    }, 200);
                }
            }
        });
        return emptyViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_HEADER_VIEW) {
        RecyclerView.ViewHolder headerViewHolder = onCreateHeaderViewHolder(parent);
        headerViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnHeaderViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnHeaderViewClickListener.onHeaderViewClick(v, v.getTag());
                        }
                    }, 200);
                }
            }
        });
        return headerViewHolder;
    }
    if (viewType == RecyclerViewMode.MODE_FOOTER_VIEW) {
        RecyclerView.ViewHolder footerViewHolder = onCreateFooterViewHolder(parent);
        footerViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(final View v) {
                if (null != mOnFooterViewClickListener) {
                    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                            mOnFooterViewClickListener.onFooterViewClick(v, v.getTag());
                        }
                    }, 200);
                }
            }
        });
        return footerViewHolder;
    }
    RecyclerView.ViewHolder dataViewHolder = onCreateDataViewHolder(parent);
    dataViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(final View v) {
            if (null != mOnItemClickListener) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mOnItemClickListener.onItemClick(v, v.getTag());
                    }
                }, 200);
            }
        }
    });
    dataViewHolder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(final View v) {
            if (null != mOnItemLongClickListener) {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mOnItemLongClickListener.onItemLongClick(v, v.getTag());
                    }
                }, 200);
                return true;
            }
            return false;
        }
    });
    return dataViewHolder;
}

5.Override the onBindViewHolder method. bind data by viewType

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    if (mMode == RecyclerViewMode.MODE_LOADING) {
        onBindLoadingViewHolder(holder, position);
    } else if (mMode == RecyclerViewMode.MODE_ERROR) {
        onBindErrorViewHolder(holder, position);
    } else if (mMode == RecyclerViewMode.MODE_EMPTY) {
        onBindEmptyViewHolder(holder, position);
    } else {

• Install qt using:

  sudo apt install qt5-qmake
  

• Open ~/.bashrc file:

  vim ~/.bashrc
  

• Added the path below to the ~/.bashrc file:

I went through a similar issue. If you consider your "YeagerTechResources.Resources", it means that your Resources.resx is at the root folder of your project.

Be careful to include the full path eg : "project\subfolder(s)\file[.resx]" to the ResourceManager constructor.

UPDATE: As was announced, Google deprecated this feature in Aug 2016. Here's the final update from Google with alternatives.

As per April 2013 and using Chrome/webkit, the following worked for me:

• 1 Make a folder called e.g. "public"

• 2 Select that folder, right click and Share > Share. Click. Select "Anyone can access"

• 3 Drag and Drop a file into the folder, and let it upload.

• 4 Right click on the file and select Details. One of the lines in the Details-Fieldset reads "Hosting". Underneath it is an url:

https://googledrive.com/...

• Drag and Drop that url into a new tab. Copy and paste the url and share or embed it anywhere you like.

One limitation is that as far as HTTP goes, only secure HTTP access seems to be possible.

Update:
Another limitation is that files which Google drive can open, won't be accessible that way.
That is, clicking on "Details" won't show an Google-drive url.

To overcome this:

• right click on the file in question and select "Open with>Manage apps":

• Untick the file-associated apps here
• Optional: Reload Google Drive
• Right click on the file and select "Details"
• Proceed as in step #4

Note: An alternative to the procedure above, is uploading the file with an extension that Google Drive cannot open/is not associated.

<script type="text/javascript">

             transport: {
                 read: {
                     url: "@Url.Action("GetMsgDetails", "OutMessage")" + "?msgId=" + msgId,
                     dataType: "json",
                 },

             batch: true,
         }),
         editable: "popup",
         columns: [
            { field: "Id", title: "Id", width: 250, hidden: true },
            { field: "Data", title: "Message Body", width: 100 },
           { field: "mobile", title: "Mobile Number", width: 100 },
         ]
     });
});

If you're using 0 and an empty string '' and null to designate undefined you've got a data problem. Just update the columns and fix your schema.

UPDATE pt.incentive_channel
SET   pt.incentive_marketing = NULL
WHERE pt.incentive_marketing = '';

UPDATE pt.incentive_channel
SET   pt.incentive_advertising = NULL
WHERE pt.incentive_marketing = '';

UPDATE pt.incentive_channel
SET   pt.incentive_channel = NULL
WHERE pt.incentive_marketing = '';

This will make joining and selecting substantially easier moving forward.

If you want to simply output a date, just use the following:

System.out.printf("Date: %1$te/%1$tm/%1$tY at %1$tH:%1$tM:%1$tS%n", new Date());

As seen here. Or if you want to get the value into a String (for SQL building, for example) you can use:

String formattedDate = String.format("%1$te/%1$tm/%1$tY", new Date());

You can also customize your output by following the Java API on Date/Time conversions.

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

Copy-pasted from here: Incrementing a date in JavaScript

Three options for you:

Using just JavaScript's Date object (no libraries):

var today = new Date();
var tomorrow = new Date(today.getTime() + (24 * 60 * 60 * 1000));

Or if you don't mind changing the date in place (rather than creating a new date):

var dt = new Date();
dt.setTime(dt.getTime() + (24 * 60 * 60 * 1000));

Edit: See also Jigar's answer and David's comment below: var tomorrow = new Date(); tomorrow.setDate(tomorrow.getDate() + 1);

Using MomentJS:

var today = moment();
var tomorrow = moment(today).add(1, 'days');

(Beware that add modifies the instance you call it on, rather than returning a new instance, so today.add(1, 'days') would modify today. That's why we start with a cloning op on var tomorrow = ....)

Using DateJS, but it hasn't been updated in a long time:

var today = new Date(); // Or Date.today()
var tomorrow = today.add(1).day();

this statement

DBMS_OUTPUT.PUT_LINE('a.firstName' || 'a.lastName');

means to print the string as it is.. remove the quotes to get the values to be printed.So the correct syntax is

DBMS_OUTPUT.PUT_LINE(a.firstName || a.lastName);

Use a tab character (\t) to separate the fields.

From, Programming Recommendations, PEP 8:

Comparisons to singletons like None should always be done with is or is not, never the equality operators.

Also, beware of writing if x when you really mean if x is not None — e.g. when testing whether a variable or argument that defaults to None was set to some other value. The other value might have a type (such as a container) that could be false in a boolean context!

PEP 8 is essential reading for any Python programmer.

Did you enable the profile for SQL Server Agent? This a common step that is missed when creating Email profiles in DatabaseMail.

Steps:

• Right-click on SQL Server Agent in Object Explorer (SSMS)
• Click on Properties
• Click on the Alert System tab in the left-hand navigation
• Enable the mail profile
• Set Mail System and Mail Profile
• Click OK
• Restart SQL Server Agent

in my case i always put these stuffs in a p tag like

<p> name : < input type=text /> </p>

and so on and then applying the css like

p {
  text-align:left;
}

p input {
  float:right;
}

You need to specify the width of the p tag.because the input tags will float all the way right.

This css will also affect the submit button. You need to override the rule for this tag.

In order to delete the 'native' node.js installation, I have used the method suggested in previous answers sudo npm uninstall npm -g, with additional sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*.

BUT, I had to also delete the following two directories:

sudo rm -rf /usr/local/include/node /Users/$USER/.npm

Only after that I could install node.js with Homebrew.

The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file.

For your purpose, you probably want something like:

FOR %i IN (*.ext) DO my-function %i

Which will result in the name of each file with extension *.ext in the current directory being passed to my-function (which could, for example, be another .bat file).

The (*.ext) part is the "filespec", and is pretty flexible with how you specify sets of files. For example, you could do:

FOR %i IN (C:\Some\Other\Dir\*.ext) DO my-function %i

To perform an operation in a different directory.

There are scores of options for the filespec and FOR in general. See

HELP FOR

from the command prompt for more information.

The WebKit Web Inspector also supports Firebug's console API (just a minor addition to Dan's answer).

This should work based on your example "2011-29-01 12:00 am"

DateTime dt;
DateTime.TryParseExact(dateTime, 
                       "yyyy-dd-MM hh:mm tt", 
                       CultureInfo.InvariantCulture, 
                       DateTimeStyles.None, 
                       out dt);

Yeah, when ASP.NET web.config gets updated, the whole application gets restarted which means the web.config gets reloaded.

Your model is @Messages, change it to @message.

To change it like you should use migration:

def change   rename_table :old_table_name, :new_table_name end 

Of course do not create that file by hand but use rails generator:

rails g migration ChangeMessagesToMessage 

That will generate new file with proper timestamp in name in 'db dir. Then run:

rake db:migrate 

And your app should be fine since then.

is using them equal to spawning background threads to perform long duration logic?

This article MDSN:Asynchronous Programming with async and await (C#) explains it explicitly:

The async and await keywords don't cause additional threads to be created. Async methods don't require multithreading because an async method doesn't run on its own thread. The method runs on the current synchronization context and uses time on the thread only when the method is active.

• System properties are set on the Java command line using the -Dpropertyname=value syntax. They can also be added at runtime using System.setProperty(String key, String value) or via the various System.getProperties().load() methods.
  To get a specific system property you can use System.getProperty(String key) or System.getProperty(String key, String def).

• Environment variables are set in the OS, e.g. in Linux export HOME=/Users/myusername or on Windows SET WINDIR=C:\Windows etc, and, unlike properties, may not be set at runtime.
  To get a specific environment variable you can use System.getenv(String name).

I got same exception while running gradle build for my android project.

Caused by: java.lang.IllegalStateException: Failed to find target with hash string 'android-27'

This issue related to android SDK version enable for your Android Studio. Please find the solution of this problem from attached screen.

I've just wasted an hour on this. I tried everything - it turned out (and I can hardly believe this) that giving my cancel button and element id of cancel meant that any attempt to prevent event propagation would fail! I guess an HTML page must treat this as someone pressing ESC?

You can use ManualResetEvent. Reset the event before you fire secondary thread and then use the WaitOne() method to block the current thread. You can then have secondary thread set the ManualResetEvent which would cause the main thread to continue. Something like this:

ManualResetEvent oSignalEvent = new ManualResetEvent(false);

void SecondThread(){
    //DoStuff
    oSignalEvent.Set();
}

void Main(){
    //DoStuff
    //Call second thread
    System.Threading.Thread oSecondThread = new System.Threading.Thread(SecondThread);
    oSecondThread.Start();

    oSignalEvent.WaitOne(); //This thread will block here until the reset event is sent.
    oSignalEvent.Reset();
    //Do more stuff
}

If you just want to list all the sites (ie. to find a binding)

Change the working directory to "C:\Windows\system32\inetsrv"

cd c:\Windows\system32\inetsrv

Next run "appcmd list sites" (plural) and output to a file. e.g c:\IISSiteBindings.txt

appcmd list sites > c:\IISSiteBindings.txt

Now open with notepad from your command prompt.

notepad c:\IISSiteBindings.txt

from r cookbook, where bp is your ggplot:

Remove legend for a particular aesthetic (fill):

bp + guides(fill=FALSE)

It can also be done when specifying the scale:

bp + scale_fill_discrete(guide=FALSE)

This removes all legends:

bp + theme(legend.position="none")

If I need to do this, I sometimes build a Set<String> of the names, or even my own Map<String,MyEnum> - then you can just check that.

A couple of points worth noting:

• Populate any such static collection in a static initializer. Don't use a variable initializer and then rely on it having been executed when the enum constructor runs - it won't have been! (The enum constructors are the first things to be executed, before the static initializer.)
• Try to avoid using values() frequently - it has to create and populate a new array each time. To iterate over all elements, use EnumSet.allOf which is much more efficient for enums without a large number of elements.

Sample code:

import java.util.*;

enum SampleEnum {
    Foo,
    Bar;

    private static final Map<String, SampleEnum> nameToValueMap =
        new HashMap<String, SampleEnum>();

    static {
        for (SampleEnum value : EnumSet.allOf(SampleEnum.class)) {
            nameToValueMap.put(value.name(), value);
        }
    }

    public static SampleEnum forName(String name) {
        return nameToValueMap.get(name);
    }
}

public class Test {
    public static void main(String [] args)
        throws Exception { // Just for simplicity!
        System.out.println(SampleEnum.forName("Foo"));
        System.out.println(SampleEnum.forName("Bar"));
        System.out.println(SampleEnum.forName("Baz"));
    }
}

Of course, if you only have a few names this is probably overkill - an O(n) solution often wins over an O(1) solution when n is small enough. Here's another approach:

import java.util.*;

enum SampleEnum {
    Foo,
    Bar;

    // We know we'll never mutate this, so we can keep
    // a local copy.
    private static final SampleEnum[] copyOfValues = values();

    public static SampleEnum forName(String name) {
        for (SampleEnum value : copyOfValues) {
            if (value.name().equals(name)) {
                return value;
            }
        }
        return null;
    }
}

public class Test {
    public static void main(String [] args)
        throws Exception { // Just for simplicity!
        System.out.println(SampleEnum.forName("Foo"));
        System.out.println(SampleEnum.forName("Bar"));
        System.out.println(SampleEnum.forName("Baz"));
    }
}

Also you can try to use

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

if you are dealing with jackson with version below 2+ (1.9.5) i tested it, you can easily use this annotation above the class. Not for specified for the attributes, just for class decleration.

iTerm handles multiple-line command perfectly, it saves multiple-lines command as one command, then we can use Cmd+ Shift + ; to navigate the history.

In case someone else finds this topic while using localhost in the file URIs - Internet Explorer acts completely different if the host name is localhost or 127.0.0.1 - if you use the actual hostname, it works fine (from trusted sites/intranet zone).

Another big difference between IE and FF - IE is fine with uris like file://server/share/file.txt but FF requires additional slashes file:////server/share/file.txt.

You can use this function if it's multiple string df[!grepl("REVERSE|GENJJS", df$Name),]

I would create an object like this:

var options = { 
    size: ["S", "M", "L", "XL", "XXL"],
    color: ["Red", "Blue", "Green", "White", "Black"]
};


alert(Object.keys(options));

To access the keys individualy:

for (var key in options) {
    alert(key);
}

P.S.: when you create a new array object do not use new Array use [] instead.

Open the sql file and comment out the line that tries to create the existing database.

You can find a comprehensive set of solutions on this in UNIX & Linux's answer to How do you move all files (including hidden) from one directory to another?. It shows solutions in Bash, zsh, ksh93, standard (POSIX) sh, etc.

You can use these two commands together:

mv /path/subfolder/* /path/   # your current approach
mv /path/subfolder/.* /path/  # this one for hidden files

Or all together (thanks pfnuesel):

mv /path/subfolder/{.,}* /path/

Which expands to:

mv /path/subfolder/* /path/subfolder/.* /path/

(example: echo a{.,}b expands to a.b ab)

Note this will show a couple of warnings:

mv: cannot move ‘/path/subfolder/.’ to /path/.’: Device or resource busy
mv: cannot remove /path/subfolder/..’: Is a directory

Just ignore them: this happens because /path/subfolder/{.,}* also expands to /path/subfolder/. and /path/subfolder/.., which are the directory and the parent directory (See What do “.” and “..” mean when in a folder?).

If you want to just copy, you can use a mere:

cp -r /path/subfolder/. /path/
#                     ^
#                     note the dot!

This will copy all files, both normal and hidden ones, since /path/subfolder/. expands to "everything from this directory" (Source: How to copy with cp to include hidden files and hidden directories and their contents?)

In Oracle 12c, you can run code both in either sequence below:

Where
Group By
Having

Or

Where 
Having
Group by

You can use canvas’ context.translate & context.rotate to do rotate your image

Here’s a function to draw an image that is rotated by the specified degrees:

function drawRotated(degrees){
    context.clearRect(0,0,canvas.width,canvas.height);

    // save the unrotated context of the canvas so we can restore it later
    // the alternative is to untranslate & unrotate after drawing
    context.save();

    // move to the center of the canvas
    context.translate(canvas.width/2,canvas.height/2);

    // rotate the canvas to the specified degrees
    context.rotate(degrees*Math.PI/180);

    // draw the image
    // since the context is rotated, the image will be rotated also
    context.drawImage(image,-image.width/2,-image.width/2);

    // we’re done with the rotating so restore the unrotated context
    context.restore();
}

Just adding my answer for the case where there are multiple versions of PHP installed in your system, and you are sure that you have already installed the php-curl package, and yet Apache is still giving you the same error.

curl_init() undefined even if php-curl is enabled in Php 7.

I was struggling with this for ages. What I finally did was go into the .npmrc file (which can be found in the user's directory followed by the user's name, ie. C:\Users\erikj/.npmrc), opened it with a text editor, manually removed any proxy settings and changed the http:// setting to https://. In this case, it is a matter of experimenting whether http or https will work for you. In my case, https worked. Go figure.

Use regular expression no need to convert it to char array

if(Regex.IsMatch("yourString",".*?[a-zA-Z].*?"))
{
errorCounter++;
}

Another common default location besides /tmp/ is /var/lib/php5/

print("\n".join(sys.path))

(The outer parentheses are included for Python 3 compatibility and are usually omitted in Python 2.)

This question is really old, but I came across this page when I was looking for the easiest and quickest way to do this. Using Webpack is much simpler:

install webpack-dev-server

npm i -g webpack-dev-server

start webpack-dev-server with https

webpack-dev-server --https

First of all, I try to install the glyphicons fonts by the "oficial" way, with the zip file. I could not do it.

This is my step-by-step solution:

1. Go to the web page of Bootstrap and then to the "Components" section.
2. Open the browser console. In Chrome, Ctrl+Shift+C.
3. In section Resources, inside Frames/getbootstrap.com/Fonts you will find the font that actually is running the glyphicons. It's recommended to use the private mode to evade cache.
4. With URL of the font file (right-click on the file showed on resources list), copy it in a new tab, and press ENTER. This will download the font file.
5. Copy another time the URL in a tab and change the font extension to eot, ttf, svg or woff, ass you like.

However, for a more easy acces, this is the link of the woff file.

http://getbootstrap.com/dist/fonts/glyphicons-halflings-regular.woff

Try this:

counter=0
while true; do
  if /home/hadoop/latest/bin/hadoop fs -ls /apps/hdtech/bds/quality-rt/dt=$DATE_YEST_FORMAT2 then
       echo "Files Present" | mailx -s "File Present"  -r [email protected] [email protected]
       break
  elif [[ "$counter" -gt 20 ]]; then
       echo "Counter limit reached, exit script."
       exit 1
  else
       let counter++
       echo "Sleeping for another half an hour" | mailx -s "Time to Sleep Now"  -r [email protected] [email protected]
       sleep 1800
  fi
done

Explanation

• break - if files are present, it will break and allow the script to process the files.
• [[ "$counter" -gt 20 ]] - if the counter variable is greater than 20, the script will exit.
• let counter++ - increments the counter by 1 at each pass.

You will have to parse the content somehow ... I find using LINQ the most easy way to do it. Again, it all depends on your exact scenario. Here's a working example using LINQ to format an input XML string.

string FormatXml(string xml)
{
     try
     {
         XDocument doc = XDocument.Parse(xml);
         return doc.ToString();
     }
     catch (Exception)
     {
         // Handle and throw if fatal exception here; don't just ignore them
         return xml;
     }
 }

[using statements are ommitted for brevity]

This can be set up on your tsconfig.json file, as it is a TS feature.

You can do like this:

"compilerOptions": {
        "baseUrl": "src", // This must be specified if "paths" is.
         ...
        "paths": {
            "@app/*": ["app/*"],
            "@config/*": ["app/_config/*"],
            "@environment/*": ["environments/*"],
            "@shared/*": ["app/_shared/*"],
            "@helpers/*": ["helpers/*"]
        },
        ...

Have in mind that the path where you want to refer to, it takes your baseUrl as the base of the route you are pointing to and it's mandatory as described on the doc.

The character '@' is not mandatory.

After you set it up on that way, you can easily use it like this:

import { Yo } from '@config/index';

the only thing you might notice is that the intellisense does not work in the current latest version, so I would suggest to follow an index convention for importing/exporting files.

Since SSRS utilizes VB, you can do the following:

=Today() 'returns date only

If you were to use:

=Now() 'returns date and current timestamp

Try this in pure bash:

FRED="/some/random/file.csv:some string"
a=${FRED%:*}
echo $a

Here is some documentation that helps.

What you might like to do is look up CSS grid based layouts. This layout method involves specifying some CSS classes to align the page contents to a grid structure. It's more closely related to print-bsed layout than web-based, but it's a technique used on a lot of websites to layout the content into a structure without having to resort to tables.

Try this for starters from Smashing Magazine.

I adopted @RobW's nice answer to get it working on Mac OS X 10.8. Other versions of Mac OS X may probably work too.

The little extra work is actually only needed to keep your original Google Chrome user settings and the old version separated.

1. Download another version of Google Chrome, like the Dev channel and extract the .app file

2. (optional) Rename it to Google Chrome X.app – if not already different from Google Chrome.app

(Be sure to replace X for all following steps with the actual version of Chrome you just downloaded)

3. Move Google Chrome X.app to /Applications without overwritting your current Chrome

4. Open the Terminal, create a shell script and make your script executable:

   cd /Applications
   touch google-chrome-version-start.sh
   chmod +x google-chrome-version-start.sh
   nano google-chrome-version-start.sh
   

5. Modify the following code according to the version you downloaded and paste it into the script

   #!/usr/bin/env bash
   /Applications/Google\ Chrome\ X.app/Contents/MacOS/Google\ Chrome\ X --user-data-dir="tmp/Google Chrome/X/" & disown
   

   For example for Dev Channel:

   #!/usr/bin/env bash
   /Applications/Google\ Chrome\ Dev.app/Contents/MacOS/Google\ Chrome\ Dev --user-data-dir="tmp/Google Chrome Dev/" & disown
   

   (This will store Chrome's data at ~/tmp/Google Chrome/VERSION/. For more explanations see the original answer.)

6. Now execute the script and be happy!

   /Application/google-chrome-version-start.sh
   

Tested it with Google Chrome 88 on a Mac running OS X 10.15 Catalina

Use <br /> for new line in html:

display_txt = display_txt.replace(/\n/g, "<br />");

I realize this has been answered many times, but this is more concise:

std::string format(const std::string fmt_str, ...)
{
    va_list ap;
    char *fp = NULL;
    va_start(ap, fmt_str);
    vasprintf(&fp, fmt_str.c_str(), ap);
    va_end(ap);
    std::unique_ptr<char[]> formatted(fp);
    return std::string(formatted.get());
}

example:

#include <iostream>
#include <random>

int main()
{
    std::random_device r;
    std::cout << format("Hello %d!\n", r());
}

The problem is with -3.7(prof[x]), which looks like a function call (note the parens). Just use a * like this -3.7*prof[x].

You can simply use setInterval utility and use arrow function as callback so that this will point to the component instance.

For ex:

this.interval = setInterval( () => { 
    // call your functions like 
    this.getList();
    this.updateInfo();
});

Inside your ngOnDestroy lifecycle hook, clear the interval.

ngOnDestroy(){
    clearInterval(this.interval);
}

I am also still figuring out the internals of git, and have figured out this so far:

1. HEAD is a file in your .git/ directory that normally looks something like this:

% cat .git/HEAD
ref: refs/heads/master

2. refs/heads/master is itself a file that normally has the hash value of the latest commit:

% cat .git/refs/heads/master 
cbf01a8e629e8d884888f19ac203fa037acd901f

3. If you git checkout a remote branch that is ahead of your master, this may cause your HEAD file to be updated to contain the hash of the latest commit in the remote master:

% cat .git/HEAD
8e2c815f83231f85f067f19ed49723fd1dc023b7

This is called a detached HEAD. The remote master is ahead of your local master. When you do git submodule --remote myrepo to get the latest commit of your submodule, it will by default do a checkout, which will update HEAD. Since your current branch master is behind, HEAD becomes 'detached' from your current branch, so to speak.

I totally agree with the opinion that premature optimization is something to avoid.

But it's true that the Java VM has special bytecodes which could be used for switch()'s.

See WM Spec (lookupswitch and tableswitch)

So there could be some performance gains, if the code is part of the performance CPU graph.

As csgillespie said. stringsAsFactors is default on TRUE, which converts any text to a factor. So even after deleting the text, you still have a factor in your dataframe.

Now regarding the conversion, there's a more optimal way to do so. So I put it here as a reference :

> x <- factor(sample(4:8,10,replace=T))
> x
 [1] 6 4 8 6 7 6 8 5 8 4
Levels: 4 5 6 7 8
> as.numeric(levels(x))[x]
 [1] 6 4 8 6 7 6 8 5 8 4

To show it works.

The timings :

> x <- factor(sample(4:8,500000,replace=T))
> system.time(as.numeric(as.character(x)))
   user  system elapsed 
   0.11    0.00    0.11 
> system.time(as.numeric(levels(x))[x])
   user  system elapsed 
      0       0       0 

It's a big improvement, but not always a bottleneck. It gets important however if you have a big dataframe and a lot of columns to convert.

In your .htaccess you can add:

PHP 5.x

<IfModule mod_php5.c>
    php_value memory_limit 64M
</IfModule>

PHP 7.x

<IfModule mod_php7.c>
    php_value memory_limit 64M
</IfModule>

If page breaks again, then you are using PHP as mod_php in apache, but error is due to something else.

If page does not break, then you are using PHP as CGI module and therefore cannot use php values - in the link I've provided might be solution but I'm not sure you will be able to apply it.

Introduction

None of the answers explain how to show last item(s) at the top. So, the answers work only for items that still have enough items above or below them to fill the remaining RecyclerView. For instance, if there are 59 elements and a 56-th element is selected it should be at the top as in the picture below:

So, let's see how to implement this in the next paragraph.

Solution

We could handle those cases by using linearLayoutManager.scrollToPositionWithOffset(pos, 0) and additional logic in the Adapter of RecyclerView - by adding a custom margin below the last item (if the last item is not visible then it means there's enough space fill the RecyclerView). The custom margin could be a difference between the root view height and the item height. So, your Adapter for RecyclerView would look as follows:

...
@Override
public void onBindViewHolder(ViewHolder holder, final int position) {
    ...

    int bottomHeight = 0;
    int itemHeight = holder.itemView.getMeasuredHeight();
    // if it's the last item then add a bottom margin that is enough to bring it to the top
    if (position == mDataSet.length - 1) {
        bottomHeight = Math.max(0, mRootView.getMeasuredHeight() - itemHeight);
    }
    RecyclerView.LayoutParams params = (RecyclerView.LayoutParams)holder.itemView.getLayoutParams();
    params.setMargins(0, 0, params.rightMargin, bottomHeight);
    holder.itemView.setLayoutParams(params);

    ...
} 
...

With python 3.6+:

msg['Subject'] = f"Auto Hella Restart Report {sys.argv[1]}"

Solution which leverages CollectionUtils subtract method:

import static org.apache.commons.collections15.CollectionUtils.subtract;

public class CollectionUtils {
  static public <T> boolean equals(Collection<? extends T> a, Collection<? extends T> b) {
    if (a == null && b == null)
      return true;
    if (a == null || b == null || a.size() != b.size())
      return false;
    return subtract(a, b).size() == 0 && subtract(a, b).size() == 0;
  }
}

This may be because, when both functions are compiled to JavaScript, their signature is totally identical. As JavaScript doesn't have types, we end up creating two functions taking same number of arguments. So, TypeScript restricts us from creating such functions.

TypeScript supports overloading based on number of parameters, but the steps to be followed are a bit different if we compare to OO languages. In answer to another SO question, someone explained it with a nice example: Method overloading?.

Basically, what we are doing is, we are creating just one function and a number of declarations so that TypeScript doesn't give compile errors. When this code is compiled to JavaScript, the concrete function alone will be visible. As a JavaScript function can be called by passing multiple arguments, it just works.

We don't stop or kill a thread rather we do Thread.currentThread().isInterrupted().

public class Task1 implements Runnable {
    public void run() {
            while (!Thread.currentThread().isInterrupted()) {
                       ................
                       ................
                       ................
                       ................
           }
    }
}

in main we will do like this:

Thread t1 = new Thread(new Task1());
t1.start();
t1.interrupt();

For C++ it depends on what you are doing. OK, it is stupid code but imagine

class myTimeEatingClass
{
 public:
 //constructor
      myTimeEatingClass()
      {
          sleep(2000);
          ms_usedTime+=2;
      }
      ~myTimeEatingClass()
      {
          sleep(3000);
          ms_usedTime+=3;
      }
      const unsigned int getTime() const
      {
          return  ms_usedTime;
      }
      static unsigned int ms_usedTime;
};

myTimeEatingClass::ms_CreationTime=0; 
myFunc()
{
    for (int counter = 0; counter <= 10; counter++) {

        myTimeEatingClass timeEater();
        //do something
    }
    cout << "Creating class took "<< timeEater.getTime() <<"seconds at all<<endl;

}
myOtherFunc()
{
    myTimeEatingClass timeEater();
    for (int counter = 0; counter <= 10; counter++) {
        //do something
    }
    cout << "Creating class took "<< timeEater.getTime() <<"seconds at all<<endl;

}

You will wait 55 seconds until you get the output of myFunc. Just because each loop contructor and destructor together need 5 seconds to finish.

You will need 5 seconds until you get the output of myOtherFunc.

Of course, this is a crazy example.

But it illustrates that it might become a performance issue when each loop the same construction is done when the constructor and / or destructor needs some time.

You can use something like this

<div class="row">
     <div class="col-xs-2">
       <select id="info_type" class="form-control">
             <option>College</option>
             <option>Exam</option>
       </select>
     </div>
</div>

http://getbootstrap.com/css/#column-sizing

In my case, I needed to find the directory name of a full path (of a directory) so I simply did:

var dirName = path.Split('\\').Last();

You probably meant document.getElementsByClassName() (and then grabbing the first item off the resulting node list):

var stopMusicExt = document.getElementsByClassName("stopButton")[0];

stopButton.onclick = function() {
    var ta = document.getElementsByClassName("stopButton")[0];
    document['player'].stopMusicExt(ta.value);
    ta.value = "";
};

You may still get the error

document.getElementsByClassName is not a function

in older browsers, though, in which case you can provide a fallback implementation if you need to support those older browsers.

function validate(){    
    var re = /^[A-Za-z]+$/;
    if(re.test(document.getElementById("textboxID").value))
       alert('Valid Name.');
    else
       alert('Invalid Name.');      
}

Alternatively here's a simple jQuery solution:

$('#menu-main > li > .dropdown-toggle').click(function () {
    window.location = $(this).attr('href');
});

Bootstrap 3

Here is a working left sidebar example:

http://bootply.com/90936 (similar to the Bootstrap docs)

The trick is using the affix component along with some CSS to position it:

  #sidebar.affix-top {
    position: static;
    margin-top:30px;
    width:228px;
  }

  #sidebar.affix {
    position: fixed;
    top:70px;
    width:228px;
  }

EDIT- Another example with footer and affix-bottom

Bootstrap 4

The Affix component has been removed in Bootstrap 4, so to create a sticky sidebar, you can use a 3rd party Affix plugin like this Bootstrap 4 sticky sidebar example, or use the sticky-top class is explained in this answer.

Related: Create a responsive navbar sidebar "drawer" in Bootstrap 4?

In the popup window, overloads the method Show() with a parameter:

Public Overloads Sub Show(Caller As Window)
    Me.Owner = Caller
    MyBase.Show()
End Sub

Then in the Main window, call your overloaded method Show():

Dim Popup As PopupWindow

Popup = New PopupWindow
Popup.Show(Me)

If you want a control to postback automatically when an event is raised, you need to set the AutoPostBack property of the control to True.

You can use

@{ WriteLiteral("html string"); }

If you have milliseconds in the date string, you can use the following.

select TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')From Dual;

And then convert it to Date with:

select trunc(TO_TIMESTAMP(SUBSTR('2020-09-10T09:37:28.378-07:00',1,23), 'YYYY-MM-DD"T"HH24:MI:SS:FF3')) From Dual;

It worked for me, hope it will help you as well.

Instead of using a PreferenceActivity to directly load preferences, use an AppCompatActivity or equivalent that loads a PreferenceFragmentCompat that loads your preferences. It's part of the support library (now Android Jetpack) and provides compatibility back to API 14.

In your build.gradle, add a dependency for the preference support library:

dependencies {
    // ...
    implementation "androidx.preference:preference:1.0.0-alpha1"
}

Note: We're going to assume you have your preferences XML already created.

For your activity, create a new activity class. If you're using material themes, you should extend an AppCompatActivity, but you can be flexible with this:

public class MyPreferencesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_preferences_activity)
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, MyPreferencesFragment())
                    .commitNow()
        }
    }
}

Now for the important part: create a fragment that loads your preferences from XML:

public class MyPreferencesFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.my_preferences_fragment); // Your preferences fragment
    }
}

For more information, read the Android Developers docs for PreferenceFragmentCompat.

Only using Session.Clear() when a user logs out can pose a security hole. As the session is still valid as far as the Web Server is concerned. It is then a reasonably trivial matter to sniff, and grab the session Id, and hijack that session.

For this reason, when logging a user out it would be safer and more sensible to use Session.Abandon() so that the session is destroyed, and a new session created (even though the logout UI page would be part of the new session, the new session would not have any of the users details in it and hijacking the new session would be equivalent to having a fresh session, hence it would be mute).

Something to consider

.isDisplayed() assumes the element is present (exists in the DOM)

so if you do

expect($('[ng-show=saving]').isDisplayed()).toBe(true);

but the element is not present, then instead of graceful failed expectation, $('[ng-show=saving]').isDisplayed() will throw an error causing the rest of it block not executed

Solution

If you assume, the element you're checking may not be present for any reason on the page, then go with a safe way below

/**
*  element is Present and is Displayed
*  @param    {ElementFinder}      $element       Locator of element
*  @return   {boolean}
*/
let isDisplayed = function ($element) {
  return (await $element.isPresent()) && (await $element.isDisplayed())
}

and use

expect(await isDisplayed( $('[ng-show=saving]') )).toBe(true);

This worked for me:

var dtFromMillisec = new Date(secs*1000);
var result = dtFromMillisec.getHours() + ":" + dtFromMillisec.getMinutes() + ":" + dtFromMillisec.getSeconds();

JSFiddle

Here's an answer in Kotlin and androidX

import android.content.Context
import android.util.AttributeSet
import android.view.MotionEvent
import androidx.viewpager.widget.ViewPager

class DeactivatedViewPager @JvmOverloads constructor(
    context: Context, attrs: AttributeSet? = null
) : ViewPager(context, attrs) {

    var isPagingEnabled = true

    override fun onTouchEvent(ev: MotionEvent?): Boolean {
        return isPagingEnabled && super.onTouchEvent(ev)
    }

    override fun onInterceptTouchEvent(ev: MotionEvent?): Boolean {
        return isPagingEnabled && super.onInterceptTouchEvent(ev)
    }
}

Sometimes you're not actually interested in the actual value, but in its usage as checksum/hashcode. In this case, the built-in method GetHashCode() is a good choice:

int checkSumAsInt32 = checkSumAsIn64.GetHashCode();

Using Blob as a source for an img:

template:

<img [src]="url">

component:

 public url : SafeResourceUrl;

 constructor(private http: HttpClient, private sanitizer: DomSanitizer) {
   this.getImage('/api/image.jpg').subscribe(x => this.url = x)
 }

 public getImage(url: string): Observable<SafeResourceUrl> {
   return this.http
     .get(url, { responseType: 'blob' })
     .pipe(
       map(x => {
         const urlToBlob = window.URL.createObjectURL(x) // get a URL for the blob
         return this.sanitizer.bypassSecurityTrustResourceUrl(urlToBlob); // tell Anuglar to trust this value
       }),
     );
 }

I'm going to assume compiling the QuickFix package does not produce a setup.py file, but rather only compiles the Python bindings and relies on make install to put them in the appropriate place.

In this case, a quick and dirty fix is to compile the QuickFix source, locate the Python extension modules (you indicated on your system these end with a .so extension), and add that directory to your PYTHONPATH environmental variable e.g., add

export PYTHONPATH=~/path/to/python/extensions:PYTHONPATH

or similar line in your shell configuration file.

A more robust solution would include making sure to compile with ./configure --prefix=$HOME/.local. Assuming QuickFix knows to put the Python files in the appropriate site-packages, when you do make install, it should install the files to ~/.local/lib/pythonX.Y/site-packages, which, for Python 2.6+, should already be on your Python path as the per-user site-packages directory.

If, on the other hand, it did provide a setup.py file, simply run

python setup.py install --user

for Python 2.6+.

There is already a transparent built into Android: R.color.transparent. http://developer.android.com/reference/android/R.color.html#transparent

But I think you may want to make the background of the image that you are placing into the WebView transparent, for example, with a transparent PNG, rather than the ImageView background. If the actual image is not at all see-through then the ImageView background can't be seen through it.

I think from the author's point of view, the main reason is to reduce the overhead for string concatenation.I just read the logger's documentation, you could find following words:

/**
* <p>This form avoids superfluous string concatenation when the logger
* is disabled for the DEBUG level. However, this variant incurs the hidden
* (and relatively small) cost of creating an <code>Object[]</code> before 
  invoking the method,
* even if this logger is disabled for DEBUG. The variants taking
* {@link #debug(String, Object) one} and {@link #debug(String, Object, Object) two}
* arguments exist solely in order to avoid this hidden cost.</p>
*/
*
 * @param format    the format string
 * @param arguments a list of 3 or more arguments
 */
public void debug(String format, Object... arguments);

I think you can use layout:weight = 5 instead android:lines = 5 because when you port your app to smaller device - it does it nicely.. well, both attributes will accomplish your job..

The issue is a missing or outdated version of MVC. I was running VS 2015Preview and could resolve the issue by installing the latest version of MVC via NuGet.

Just in case anyone is still coming across this one.

Here's another way to do it instead of using foreach loops for looking inside EntityValidationErrors. Of course you can format the message to your own liking :

try {
        // your code goes here...
    } 
catch (DbEntityValidationException ex) 
    {
        Console.Write($"Validation errors: {string.Join(Environment.NewLine, ex.EntityValidationErrors.SelectMany(vr => vr.ValidationErrors.Select(err => $"{err.PropertyName} - {err.ErrorMessage}")))}", ex);
        throw;
    }

Your question implies that you're building the INSERT statement up by concatenating strings together. I suggest that this is a poor choice as it leaves you open to SQL injection attacks if the strings are derived from user input. A better choice is to use parameter markers and to bind the values to the markers. If you search for Oracle parameter markers you'll probably find some information for your specific implementation technology (e.g. C# and ADO, Java and JDBC, Ruby and RubyDBI, etc).

Share and enjoy.

Properties in your object are value types and you can use the shallow copy in such situation like that:

obj myobj2 = (obj)myobj.MemberwiseClone();

But in other situations, like if any members are reference types, then you need Deep Copy. You can get a deep copy of an object using Serialization and Deserialization techniques with the help of BinaryFormatter class:

public static T DeepCopy<T>(T other)
{
    using (MemoryStream ms = new MemoryStream())
    {
        BinaryFormatter formatter = new BinaryFormatter();
        formatter.Context = new StreamingContext(StreamingContextStates.Clone);
        formatter.Serialize(ms, other);
        ms.Position = 0;
        return (T)formatter.Deserialize(ms);
    }
}

The purpose of setting StreamingContext: We can introduce special serialization and deserialization logic to our code with the help of either implementing ISerializable interface or using built-in attributes like OnDeserialized, OnDeserializing, OnSerializing, OnSerialized. In all cases StreamingContext will be passed as an argument to the methods(and to the special constructor in case of ISerializable interface). With setting ContextState to Clone, we are just giving hint to that method about the purpose of the serialization.

Additional Info: (you can also read this article from MSDN)

Shallow copying is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed; for a reference type, the reference is copied but the referred object is not; therefore the original object and its clone refer to the same object.

Deep copy is creating a new object and then copying the nonstatic fields of the current object to the new object. If a field is a value type, a bit-by-bit copy of the field is performed. If a field is a reference type, a new copy of the referred object is performed.

If you are just trying to open a file, you could use app.open_resource(). So reading a file would look something like

with app.open_resource('/static/path/yourfile'):
      #code to read the file and do something

Use a set to intersect on the dict.viewkeys() dictionary view:

l = {1, 5}
{key: d[key] for key in d.viewkeys() & l}

This is Python 2 syntax, in Python 3 use d.keys().

This still uses a loop, but at least the dictionary comprehension is a lot more readable. Using set intersections is very efficient, even if d or l is large.

Demo:

>>> d = {1:2, 3:4, 5:6, 7:8}
>>> l = {1, 5}
>>> {key: d[key] for key in d.viewkeys() & l}
{1: 2, 5: 6}

        try {
            FileReader fReader = new FileReader(file);
            BufferedReader fileBuff = new BufferedReader(fReader);
            while ((line = fileBuff.readLine()) != null) {
                fileContents.add(line);
            }
            fileBuff.close();
        } catch (Exception e) {
            System.out.println(e.getMessage());

        System.out.println(fileContents.contains("Mark Sagal"));
    }
}

Two things. First, you must base64 decode the mykey.pem file yourself. Second, the openssl private key format is specified in PKCS#1 as the RSAPrivateKey ASN.1 structure. It is not compatible with java's PKCS8EncodedKeySpec, which is based on the SubjectPublicKeyInfo ASN.1 structure. If you are willing to use the bouncycastle library you can use a few classes in the bouncycastle provider and bouncycastle PKIX libraries to make quick work of this.

import java.io.BufferedReader;
import java.io.FileReader;
import java.security.KeyPair;
import java.security.Security;

import org.bouncycastle.jce.provider.BouncyCastleProvider;
import org.bouncycastle.openssl.PEMKeyPair;
import org.bouncycastle.openssl.PEMParser;
import org.bouncycastle.openssl.jcajce.JcaPEMKeyConverter;

// ...   

String keyPath = "mykey.pem";
BufferedReader br = new BufferedReader(new FileReader(keyPath));
Security.addProvider(new BouncyCastleProvider());
PEMParser pp = new PEMParser(br);
PEMKeyPair pemKeyPair = (PEMKeyPair) pp.readObject();
KeyPair kp = new JcaPEMKeyConverter().getKeyPair(pemKeyPair);
pp.close();
samlResponse.sign(Signature.getInstance("SHA1withRSA").toString(), kp.getPrivate(), certs);

Any of the following will work:

print 'Hello\nWorld'

print 'Hello'
print 'World'

Additionally, if you want to print a blank line (not make a new line), print or print() will work.

They are probably using a virtual host (http://www.keanei.com/2011/07/14/creating-virtual-hosts-with-wamp/)

You can go into your Apache configuration file (httpd.conf) or your virtual host configuration file (recommended) and add something like:

<VirtualHost *:80>
    DocumentRoot /www/ap-mispro
    ServerName ap-mispro

    # Other directives here
</VirtualHost>

And when you call up http://ap-mispro/ you would see whatever is in C:/wamp/www/ap-mispro (assuming default directory structure). The ServerName and DocumentRoot do no have to have the same name at all. Other factors needed to make this work:

1. You have to make sure httpd-vhosts.conf is included by httpd.conf for your changes in that file to take effect.
2. When you make changes to either file, you have to restart Apache to see your changes.
3. You have to change your hosts file http://en.wikipedia.org/wiki/Hosts_(file) for your computer to know where to go when you type http://ap-mispro into your browser. This change to your hosts file will only apply to your computer - not that it sounds like you are trying from anyone else's.

There are plenty more things to know about virtual hosts but this should get you started.

In JavaScript, we can close a window only if it is opened by using window.open method:

window.open('https://www.google.com');
window.close();

But to close a window which has not been opened using window.open(), you must

1. Open any other URL or a blank page in the same tab
2. Close this newly opened tab (this will work because it was opened by window.open())

window.open("", "_self");
window.close();

The password of the debug certificate is android and not Android

display: inline-block; will prevent break between the words in a list item

 li {
    display: inline-block;
 }

request.POST is just a dictionary-like object, so just index into it with dict syntax.

Assuming your form field is fred, you could do something like this:

if 'fred' in request.POST:
    mydata = request.POST['fred']

Alternately, use a form object to deal with the POST data.

It appears that the use of SAPPLY on a data.frame to convert variables to factors at once does not work as it produces a matrix/ array. My approach is to use LAPPLY instead, as follows.

## let us create a data.frame here

class <- c("7", "6", "5", "3")

cash <- c(100, 200, 300, 150)

height <- c(170, 180, 150, 165)

people <- data.frame(class, cash, height)

class(people) ## This is a dataframe 

## We now apply lapply to the data.frame as follows.

bb <- lapply(people, as.factor) %>% data.frame() 

## The lapply part returns a list which we coerce back to a data.frame

class(bb) ## A data.frame

##Now let us check the classes of the variables 

class(bb$class)

class(bb$height)

class(bb$cash) ## as expected, are all factors. 

I'd have done it like this:

perl -e 'while (<>) {chop; $h{$_}++;} for $k (keys %h) {print "$k $h{$k}\n";}' ip_addresses

but uniq might work for you.

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

For Ruby Mine users on Windows:

Open file in editor Select the block and press Ctrl+forward slash, you will have selected block starting with #.

Now if you want to un-comment the commented block, press same key combination Ctrl+forward slash again

As far as i experienced zposition is a best way.

self.view.layer.zPosition = 1;

To call a controller function in parent scope from inside an isolate scope directive, use dash-separated attribute names in the HTML like the OP said.

Also if you want to send a parameter to your function, call the function by passing an object:

<test color1="color1" update-fn="updateFn(msg)"></test>

JS

var app = angular.module('dr', []);

app.controller("testCtrl", function($scope) {
    $scope.color1 = "color";
    $scope.updateFn = function(msg) {        
        alert(msg);
    }
});

app.directive('test', function() {
    return {
        restrict: 'E',
        scope: {
            color1: '=',
            updateFn: '&'
        },
        // object is passed while making the call
        template: "<button ng-click='updateFn({msg : \"Hello World!\"})'>
            Click</button>",
        replace: true,        
        link: function(scope, elm, attrs) {             
        }
    }
});

Fiddle

mkoryak is correct.

But, if events are bound to that DOM node using more modern methods (not using onclick), then this method will fail.

If that is what you really want, check out this question, and its accepted answer.

Cheers!

I read your question again.
I'd like to tell you this: don't use onclick, onkeypress and the likes to bind events.

Using better methods like addEventListener() will enable you to:

1. Add more than one event handler to a particular event
2. remove some listeners selectively

Instead of actually using addEventListener(), you could use jQuery wrappers like $('selector').click().

Cheers again!
