Programs & Examples On #Pdf extraction

For JSON data, it's much easier to POST it as "application/json" content-type. If you use GET, you have to URL-encode the JSON in a parameter and it's kind of messy. Also, there is no size limit when you do POST. GET's size if very limited (4K at most).

I'm trying to find a method to redirect my request from filter to login page

Don't

You just invoke

chain.doFilter(request, response);

from filter and the normal flow will go ahead.

I don't know how to redirect from servlet

You can use

response.sendRedirect(url);

to redirect from servlet

You can use this code

var str="test_String_ABC";_x000D_
var strReplacedWith=" and ";_x000D_
var currentIndex = str.lastIndexOf("_");_x000D_
str = str.substring(0, currentIndex) + strReplacedWith + str.substring(currentIndex + 1, str.length);_x000D_
_x000D_
alert(str);

There is no reliable way to check this. It's really under client's hand to tell you where it came from. You could imagine to use cookie or sessions informations put only on some pages of your website, but doing so your would break user experience with bookmarks.

I got into a really silly state, I doubt anyone else will find this useful.... but just in case

git ls-remote origin
0d2ab882d0dd5a6db93d7ed77a5a0d7b258a5e1b        HEAD
6f96ad0f97ee832ee16007d865aac9af847c1ef6        refs/heads/HEAD
0d2ab882d0dd5a6db93d7ed77a5a0d7b258a5e1b        refs/heads/master

which I eventually fixed with

git push origin :HEAD

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

To merge only the changes from branch2's file.py, make the other changes go away.

git checkout -B wip branch2
git read-tree branch1
git checkout branch2 file.py
git commit -m'merging only file.py history from branch2 into branch1'
git checkout branch1
git merge wip

Merge will never even look at any other file. You might need to '-f' the checkouts if the trees are different enough.

Note that this will leave branch1 looking as if everything in branch2's history to that point has been merged, which may not be what you want. A better version of the first checkout above is probably

git checkout -B wip `git merge-base branch1 branch2`

in which case the commit message should probably also be

git commit -m"merging only $(git rev-parse branch2):file.py into branch1"

I personally use the Jackson module for Kotlin that you can find here: jackson-module-kotlin.

implementation "com.fasterxml.jackson.module:jackson-module-kotlin:$version"

As an example, here is the code to parse the JSON of the Path of Exile skilltree which is quite heavy (84k lines when formatted) :

Kotlin code:

package util

    convert( jsonFile )

Given your description, I believe it matches your needs.

The following worked really well for me. I needed to redraw the datatable with a different subset of the data based on a parameter.

table.ajax.url('NewDataUrl?parameter=' + param).load();

If your data is static, then use this:

table.ajax.url('NewDataUrl').load();

SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.

You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...

From there wizard should be self-explanatory and easy to navigate. You choose your CSV as source, desired destination, configure columns and run the package.

If you need detailed guidance, there are plenty of guides online, here is a nice one: http://www.mssqltips.com/sqlservertutorial/203/simple-way-to-import-data-into-sql-server/

With library(lubridate), numeric representations of date and time saved as the number of seconds since 1970-01-01 00:00:00 UTC, can be coerced into dates with as_datetime():

lubridate::as_datetime(1352068320)

[1] "2012-11-04 22:32:00 UTC"

You could always use array methods:

var slides = getElementsByClassName("slide");
Array.prototype.forEach.call(slides, function(slide, index) {
    Distribute(slides.item(index));
});

Most databases have a native UUID type these days to make working with them easier. If yours doesn't, they're just 128-bit numbers, so you can use BINARY(16), and if you need the text format frequently, e.g. for troubleshooting, then add a calculated column to generate it automatically from the binary column. There is no good reason to store the (much larger) text form.

And with the new string formatting method...

f = open('{0}.csv'.format(name), 'wb')

Considering Ionic's ability to cache view elements and scope data mentioned above, this might be another way of doing, if you want to run the controller every time the view gets loaded. You can globally disable the caching mechanism used by ionic by doing:

$ionicConfigProvider.views.maxCache(0);

Else, the way I had it working for me was doing

$scope.$on("$ionicView.afterLeave", function () {
     $ionicHistory.clearCache();
}); 

This is to clear the cache before leaving the view to re-run controller every time you enter back again.

this works with me for inline datepicker (and the other)

$('#startdate').data('datepicker').date

Summing up what the others have suggested, and adding a third way

You can:

• assign(**kwargs):

   df.assign(Name='abc')
  

• access the new column series (it will be created) and set it:

   df['Name'] = 'abc'
  

• insert(loc, column, value, allow_duplicates=False)

   df.insert(0, 'Name', 'abc')
  

where the argument loc ( 0 <= loc <= len(columns) ) allows you to insert the column where you want.

'loc' gives you the index that your column will be at after the insertion. For example, the code above inserts the column Name as the 0-th column, i.e. it will be inserted before the first column, becoming the new first column. (Indexing starts from 0).

All these methods allow you to add a new column from a Series as well (just substitute the 'abc' default argument above with the series).

The Corona SDK (Ansca Mobile) uses Lua as its coding language. See lua.org for more about Lua.

While we plan to add further web integration and native-UI elements, our focus will tend to be on graphics-intensive applications, such as game development, as opposed to web-based technologies. In other words, we don't envision people writing Corona apps entirely in Javascript/HTML/CSS.

import binascii

binary_string = binascii.unhexlify(hex_string)

Read

binascii.unhexlify

Return the binary data represented by the hexadecimal string specified as the parameter.

To combine both Nitzan's and Edwin's answers, I found that something like this works for me:

update = (e: React.FormEvent<EventTarget>): void => {
    let target = e.target as HTMLInputElement;
    this.props.login[target.name] = target.value;
}

For me, all I had to do it uninstalling VMware.

Docker now is running

Try this.For swift.

func checkCardValidation(number : String) -> Bool
{
    let reversedInts = number.characters.reversed().map { Int(String($0)) }
        return reversedInts.enumerated().reduce(0, {(sum, val) in
            let odd = val.offset % 2 == 1
            return sum + (odd ? (val.element! == 9 ? 9 : (val.element! * 2) % 9) : val.element!)
        }) % 10 == 0
}

Use.

if (self.checkCardValidation(number: "yourNumber") == true) {
     print("Card Number valid")
}else{
     print("Card Number not valid")
}

if (android.os.Build.VERSION.SDK_INT >= 21) {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position], context.getTheme()));
} else {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position]));
}

Use a simple python wget module to download the link. Usage below:

import wget
wget.download('http://www.digimouth.com/news/media/2011/09/google-logo.jpg')

When you create database or create tables

You should add that line at top script create database or table

SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=1;

Now you want to delete records from table? then you write as

SET @OLD_FOREIGN_KEY_CHECKS=@@FOREIGN_KEY_CHECKS, FOREIGN_KEY_CHECKS=1;
DELETE FROM `jobs` WHERE `job_id` =1 LIMIT 1

Good luck!

This depends on how you installed TensorFlow. I am going to use the same headings used by TensorFlow's installation instructions to structure this answer.

Pip installation

Run:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 2
python3 -c 'import tensorflow as tf; print(tf.__version__)'  # for Python 3

Note that python is symlinked to /usr/bin/python3 in some Linux distributions, so use python instead of python3 in these cases.

pip list | grep tensorflow for Python 2 or pip3 list | grep tensorflow for Python 3 will also show the version of Tensorflow installed.

Virtualenv installation

Run:

python -c 'import tensorflow as tf; print(tf.__version__)'  # for both Python 2 and Python 3

pip list | grep tensorflow will also show the version of Tensorflow installed.

For example, I have installed TensorFlow 0.9.0 in a virtualenv for Python 3. So, I get:

$ python -c 'import tensorflow as tf; print(tf.__version__)'
0.9.0

$ pip list | grep tensorflow
tensorflow (0.9.0)

This is the effect that we're trying to achieve:

The classes that need to be applied changed with the release of Bootstrap 3.1.0 and again with the release of Bootstrap 4. If one of the below solutions doesn't seem to be working double check the version number of Bootstrap that you're importing and try a different one.

Bootstrap 3

Before v3.1.0

You can use the pull-right class to line the right hand side of the menu up with the caret:

<li class="dropdown">
  <a class="dropdown-toggle" href="#">Link</a>
  <ul class="dropdown-menu pull-right">
     <li>...</li>
  </ul>
</li>

Fiddle: http://jsfiddle.net/joeczucha/ewzafdju/

After v3.1.0

As of v3.1.0, we've deprecated .pull-right on dropdown menus. To right-align a menu, use .dropdown-menu-right. Right-aligned nav components in the navbar use a mixin version of this class to automatically align the menu. To override it, use .dropdown-menu-left.

You can use the dropdown-right class to line the right hand side of the menu up with the caret:

<li class="dropdown">
  <a class="dropdown-toggle" href="#">Link</a>
  <ul class="dropdown-menu dropdown-menu-right">
     <li>...</li>
  </ul>
</li>

Fiddle: http://jsfiddle.net/joeczucha/1nrLafxc/

Bootstrap 4

The class for Bootstrap 4 are the same as Bootstrap > 3.1.0, just watch out as the rest of the surrounding markup has changed a little:

<li class="nav-item dropdown">
  <a class="nav-link dropdown-toggle" href="#">
    Link
  </a>
  <div class="dropdown-menu dropdown-menu-right">
    <a class="dropdown-item" href="#">...</a>
  </div>
</li>

I want to leave this here because I struggled with this when compiling for Android in Windows with the Android SDK.

CMake distinguishes between TARGET and HOST platform.

My TARGET was Android so the variables like CMAKE_SYSTEM_NAME had the value "Android" and the variable WIN32 from the other answer here was not defined. But I wanted to know if my HOST system was Windows because I needed to do a few things differently when compiling on either Windows or Linux or IOs. To do that I used CMAKE_HOST_SYSTEM_NAME which I found is barely known or mentioned anywhere because for most people TARGEt and HOST are the same or they don't care.

Hope this helps someone somewhere...

You could try something like this:

...Binding="{Binding RelativeSource={RelativeSource FindAncestor, 
AncestorType={x:Type Window}}, Path=DataContext.AllowItemCommand}" ...

Use JAXP and forget about text handling it will be done for you automatically.

this can help to evaluate http status

I don't usually resurrect old threads but there is a lot on churn here and sans the rimraf answer these all seem overly complicated to me.

First in modern Node (>= v8.0.0) you can simplify the process using only node core modules, fully asynchronous, and parallelize the unlinking of files concurrently all in a function of five lines and still keep readability:

const fs = require('fs');
const path = require('path');
const { promisify } = require('util');
const readdir = promisify(fs.readdir);
const rmdir = promisify(fs.rmdir);
const unlink = promisify(fs.unlink);

exports.rmdirs = async function rmdirs(dir) {
  let entries = await readdir(dir, { withFileTypes: true });
  await Promise.all(entries.map(entry => {
    let fullPath = path.join(dir, entry.name);
    return entry.isDirectory() ? rmdirs(fullPath) : unlink(fullPath);
  }));
  await rmdir(dir);
};

On another note a guard for path traversal attacks is inappropriate for this function because

1. It is out of scope based on the Single Responsibility Principle.
2. Should be handled by the caller not this function. This is akin to the command-line rm -rf in that it takes an argument and will allow the user to rm -rf / if asked to. It would be the responsibility of a script to guard not the rm program itself.
3. This function would be unable to determine such an attack since it does not have a frame of reference. Again that is the responsibility of the caller who would have the context of intent which would provide it a reference to compare the path traversal.
4. Sym-links are not a concern as .isDirectory() is false for sym-links and are unlinked not recursed into.

Last but not least, there is a rare race condition that the recursion could error if one of the entries was unlinked or deleted outside this script at just the right time while this recursion is running. Since this scenario is not typical in most environments it can likely be overlooked. However, if required (for some edge cases) this issue can be mitigated with this slightly more complex example:

exports.rmdirs = async function rmdirs(dir) {
  let entries = await readdir(dir, { withFileTypes: true });
  let results = await Promise.all(entries.map(entry => {
    let fullPath = path.join(dir, entry.name);
    let task = entry.isDirectory() ? rmdirs(fullPath) : unlink(fullPath);
    return task.catch(error => ({ error }));
  }));
  results.forEach(result => {
    // Ignore missing files/directories; bail on other errors
    if (result && result.error.code !== 'ENOENT') throw result.error;
  });
  await rmdir(dir);
};

EDIT: Make isDirectory() a function. Remove the actual directory at the end. Fix missing recursion.

Similarly:

"".contains("");     // Returns true.

Therefore, it appears that an empty string is contained in any String.

Here is an example from my HOW TO Matlab page:

close all; clear all;

img   = imread('lena.tif','tif');
imagesc(img)
img   = fftshift(img(:,:,2));
F     = fft2(img);

figure;

imagesc(100*log(1+abs(fftshift(F)))); colormap(gray); 
title('magnitude spectrum');

figure;
imagesc(angle(F));  colormap(gray);
title('phase spectrum');

This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.

ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say

img = imread('ngc6543a.jpg');

and it will work. I used an older version of Matlab to make the above example and just copied it here.

On the scaling factor

When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c value in the equation

s = c log(1+r) 

There is no known way to pre detrmine this scale that I know. Just need to try different values to get on you like. I used 100 in the above example.

Solution found here : https://sourceforge.net/p/ipt-netflow/bugs-requests-patches/53/

The solution is : $(CURDIR)

You can use it like that :

CUR_DIR = $(CURDIR)

## Start :
start:
    cd $(CUR_DIR)/path_to_folder

In Python 2.x this is not guaranteed as it is possible for True and False to be reassigned. However, even if this happens, boolean True and boolean False are still properly returned for comparisons.

In Python 3.x True and False are keywords and will always be equal to 1 and 0.

Under normal circumstances in Python 2, and always in Python 3:

False object is of type bool which is a subclass of int:

object
   |
 int
   |
 bool

It is the only reason why in your example, ['zero', 'one'][False] does work. It would not work with an object which is not a subclass of integer, because list indexing only works with integers, or objects that define a __index__ method (thanks mark-dickinson).

Edit:

It is true of the current python version, and of that of Python 3. The docs for python 2 and the docs for Python 3 both say:

There are two types of integers: [...] Integers (int) [...] Booleans (bool)

and in the boolean subsection:

Booleans: These represent the truth values False and True [...] Boolean values behave like the values 0 and 1, respectively, in almost all contexts, the exception being that when converted to a string, the strings "False" or "True" are returned, respectively.

There is also, for Python 2:

In numeric contexts (for example when used as the argument to an arithmetic operator), they [False and True] behave like the integers 0 and 1, respectively.

So booleans are explicitly considered as integers in Python 2 and 3.

So you're safe until Python 4 comes along. ;-)

You can use the Logical NOT ! operator:

if (!$(this).parent().next().is('ul')){

Or equivalently (see comments below):

if (! ($(this).parent().next().is('ul'))){

For more information, see the Logical Operators section of the MDN docs.

This will print out a hexadecimal representation of a pthread_t, no matter what that actually is:

void fprintPt(FILE *f, pthread_t pt) {
  unsigned char *ptc = (unsigned char*)(void*)(&pt);
  fprintf(f, "0x");
  for (size_t i=0; i<sizeof(pt); i++) {
    fprintf(f, "%02x", (unsigned)(ptc[i]));
  }
}

To just print a small id for a each pthread_t something like this could be used (this time using iostreams):

void printPt(std::ostream &strm, pthread_t pt) {
  static int nextindex = 0;
  static std::map<pthread_t, int> ids;
  if (ids.find(pt) == ids.end()) {
    ids[pt] = nextindex++;
  }
  strm << ids[pt];
}

Depending on the platform and the actual representation of pthread_t it might here be necessary to define an operator< for pthread_t, because std::map needs an ordering on the elements:

bool operator<(const pthread_t &left, const pthread_t &right) {
  ...
}

In iOS 10, and on newer iPhones, you can also use haptic API. This haptic feedback is softer than the AudioToolbox API.

For your GAME OVER scenario, a heavy UI impact feedback should be suitable.

UIImpactFeedbackGenerator(style: .heavy).impactOccurred()

You could use the other haptic feedback styles.

function abc() {
    var color = document.getElementById("test").style.color;
    color = (color=="red") ? "black" : "red" ;
    document.getElementById("test").style.color= color;
}

If the list of conditions is not known at compile time and is instead built at run time, you don't have to worry about whether you have one or more than one condition. You can generate them all like:

and <condition>

and concatenate them all together. With the 1=1 at the start, the initial and has something to associate with.

I've never seen this used for any kind of injection protection, as you say it doesn't seem like it would help much. I have seen it used as an implementation convenience. The SQL query engine will end up ignoring the 1=1 so it should have no performance impact.

Try this:

find /var/tmp -mtime +2 -a -mtime -8 -ls

to find files older than 2 days but not older than 8 days.

Do not use Mockito.anyXXXX(). Directly pass the value to the method parameter of same type. Example:

A expected = new A(10);

String firstId = "10w";
String secondId = "20s";
String product = "Test";
String type = "type2";
Mockito.when(service.getTestData(firstId, secondId, product,type)).thenReturn(expected);

public class A{
   int a ;
   public A(int a) {
      this.a = a;
   }
}

I know this is a little late, but if someone else comes across this looking, you can now use public_path(); in Laravel 4, it has been added to the helper.php file in the support folder see here.

Unless you are subtracting dates on same browser client and don't care about edge cases like day light saving time changes, you are probably better off using moment.js which offers powerful localized APIs. For example, this is what I have in my utils.js:

subtractDates: function(date1, date2) {
    return moment.subtract(date1, date2).milliseconds();
},
millisecondsSince: function(dateSince) {
    return moment().subtract(dateSince).milliseconds();
},

this should work out,

      kable(dt) %>%
      kable_styling("striped") %>%
      add_header_above(c(" " = 1, "Group 1" = 2, "Group 2" = 2, "Group 3" = 2))
#OR
kable(dt) %>%
  kable_styling(c("striped", "bordered")) %>%
  add_header_above(c(" ", "Group 1" = 2, "Group 2" = 2, "Group 3" = 2)) %>%
  add_header_above(c(" ", "Group 4" = 4, "Group 5" = 2)) %>%
  add_header_above(c(" ", "Group 6" = 6))

for more you can check the link

You can use btoa (to base-64) and atob (from base-64).

For IE 9 and below, try the jquery-base64 plugin:

$.base64.encode("this is a test");
$.base64.decode("dGhpcyBpcyBhIHRlc3Q=");

One option would be to include function.cpp in your UnitTest1 project, but that may not be the most ideal solution structure. The short answer to your problem is that when building your UnitTest1 project, the compiler and linker have no idea that function.cpp exists, and also have nothing to link that contains a definition of multiple. A way to fix this is making use of linking libraries.

Since your unit tests are in a different project, I'm assuming your intention is to make that project a standalone unit-testing program. With the functions you are testing located in another project, it's possible to build that project to either a dynamically or statically linked library. Static libraries are linked to other programs at build time, and have the extension .lib, and dynamic libraries are linked at runtime, and have the extension .dll. For my answer I'll prefer static libraries.

You can turn your first program into a static library by changing it in the projects properties. There should be an option under the General tab where the project is set to build to an executable (.exe). You can change this to .lib. The .lib file will build to the same place as the .exe.

In your UnitTest1 project, you can go to its properties, and under the Linker tab in the category Additional Library Directories, add the path to which MyProjectTest builds. Then, for Additional Dependencies under the Linker - Input tab, add the name of your static library, most likely MyProjectTest.lib.

That should allow your project to build. Note that by doing this, MyProjectTest will not be a standalone executable program unless you change its build properties as needed, which would be less than ideal.

this is my first code on this site try this

import java.util.Scanner;
public class BATM {

public static void main(String[] args) {
    Scanner input = new Scanner(System.in);

    String username;
    String password;

    System.out.println("Log in:");
    System.out.println("username: ");
    username = input.next();

    System.out.println("password: ");
    password = input.next();

    //users check = new users(username, password);

    if(username.equals(username) && password.equals(password)) 
        System.out.println("You are logged in");



}

}

Make sure you have commented out any commentaries. Sometimes when copying and pasting you will leave out the "/*!"

Also when you go into the console they will list your errors and you should take it one at a time. If you see "Uncaught SyntaxError: Unexpected token * " That might mean it is reading your js file and it isn't getting past the first line.

You typically have to do this in a single syscall, or else you will get a race condition.

This will open for reading and writing, creating the file if necessary.

FILE *fp = fopen("scores.dat", "ab+");

If you want to read it and then write a new version from scratch, then do it as two steps.

FILE *fp = fopen("scores.dat", "rb");
if (fp) {
    read_scores(fp);
}

// Later...

// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
    error();
write_scores(fp);

Single quotes are escaped by doubling them up,

The following SQL illustrates this functionality.

declare @person TABLE (
    [First] nvarchar(200),
    [Last] nvarchar(200)
)

insert into @person 
    (First, Last)
values
    ('Joe', 'O''Brien')

select * from @person

Results

First   | Last
===================
Joe     | O'Brien

A great way to find out:

public static void main(String args[]) {
    int i = null;
}

Try to compile.

Is there such a thing as destructors for ECMAScript 6?

No. EcmaScript 6 does not specify any garbage collection semantics at all^[1], so there is nothing like a "destruction" either.

If I register some of my object's methods as event listeners in the constructor, I want to remove them when my object is deleted

A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered.
What you are actually looking for is a method of registering listeners without marking them as live root objects. (Ask your local eventsource manufacturer for such a feature).

_{1): Well, there is a beginning with the specification of WeakMap and WeakSet objects. However, true weak references are still in the pipeline [1][2].}

For whom are using Spring Boot, you can configure the default behaviour of Jackson by using the Jackson2ObjectMapperBuilder.

For example :

@Bean
public Jackson2ObjectMapperBuilder configureObjectMapper() {
    Jackson2ObjectMapperBuilder oMapper = new Jackson2ObjectMapperBuilder();
    oMapper.failOnUnknownProperties(false);
    return oMapper;
}

Then you can autowire the ObjectMapper everywhere you need it (by default, this object mapper will also be used for http content conversion).

I understand this question is for sql server 2012, but if the same scenario for SQL Server 2017 or SQL Azure you can use Trim directly as below:

UPDATE *tablename*
   SET *columnname* = trim(*columnname*);

You could try this:

#include <stdio.h>

int main() 
{  
  int i,j;
  int my_array[3][3] ={10, 23, 42, 1, 654, 0, 40652, 22, 0};
  for(i = 0; i < 3; i++) 
  {
       for(j = 0; j < 3; j++) 
       {
         printf("%d ", my_array[i][j]);
       }
    printf("\n");
  } 
  return 0;
}

If the problem is not solved by above answer, check whether the Windows SDK version is 10.0.15063.0.

Project -> Properties -> General -> Windows SDK Version -> select 10.0.15063.0

After this rebuild the solution.  

On Windows:

CHDIR Displays the name of or changes the current directory.

In Linux:

PWD Displays the name of current directory.

So before I found this post, I successfully found this to work.

Model._meta.fields

It works equally as

Model._meta.get_fields()

I'm not sure what the difference is in the results, if there is one. I ran this loop and got the same output.

for field in Model._meta.fields:
    print(field.name)

In Jupyter Lab 2.1.5, it is View -> Show Line Numbers.

Work 100% sure try this code for the get all hashmap key and value

static HashMap<String, String> map = new HashMap<>();

map.put("one"  " a " );
map.put("two"  " b " );
map.put("three"  " c " );
map.put("four"  " d " );

just call this method whenever you want to show the HashMap value

 private void ShowHashMapValue() {

        /**
         * get the Set Of keys from HashMap
         */
        Set setOfKeys = map.keySet();

/**
 * get the Iterator instance from Set
 */
        Iterator iterator = setOfKeys.iterator();

/**
 * Loop the iterator until we reach the last element of the HashMap
 */
        while (iterator.hasNext()) {
/**
 * next() method returns the next key from Iterator instance.
 * return type of next() method is Object so we need to do DownCasting to String
 */
            String key = (String) iterator.next();

/**
 * once we know the 'key', we can get the value from the HashMap
 * by calling get() method
 */
            String value = map.get(key);

            System.out.println("Key: " + key + ", Value: " + value);
        }
    } 

The code is very long so I can't paste all the code.

There could be any number of reasons why your code doesn't work. Maybe you declared the button variables twice so you aren't actually changing enabling/disabling the button like you think you are. Maybe you are blocking the EDT.

You need to create a SSCCE to post on the forum.

So its up to you to isolate the problem. Start with a simple frame thas two buttons and see if your code works. Once you get that working, then try starting a Thread that simply sleeps for 10 seconds to see if it still works.

Learn how the basice work first before writing a 200 line program.

Learn how to do some basic debugging, we are not mind readers. We can't guess what silly mistake you are doing based on your verbal description of the problem.

mysqli:query() returns a mysqli_result object, which cannot be serialized into a string.

You need to fetch the results from the object. Here's how to do it.

If you need a single value.

Fetch a single row from the result and then access column index 0 or using an associative key. Use the null-coalescing operator in case no rows are present in the result.

$result = $con->query($tourquery);  // or mysqli_query($con, $tourquery);

$tourresult = $result->fetch_array()[0] ?? '';
// OR
$tourresult = $result->fetch_array()['roomprice'] ?? '';

echo '<strong>Per room amount:  </strong>'.$tourresult;

If you need multiple values.

Use foreach loop to iterate over the result and fetch each row one by one. You can access each column using the column name as an array index.

$result = $con->query($tourquery);  // or mysqli_query($con, $tourquery);

foreach($result as $row) {
    echo '<strong>Per room amount:  </strong>'.$row['roomprice'];
}

"Ambiguous column" usually means that the same column name appears in at least two tables; the database engine can't tell which one you want. Use full table names or table aliases to remove the ambiguity.

Here's an example I happened to have in my editor. It's from someone else's problem, but should make sense anyway.

select P.* 
from product_has_image P
inner join highest_priority_images H 
        on (H.id_product = P.id_product and H.priority = p.priority)

Just a quick chime in here to hopefully help others... Especially with the newer version (since this is 2 years old)...

Instead of having some static fields defined in JS, you can also use the data-rule-* attributes. You can use built-in rules as well as custom rules.

See http://jqueryvalidation.org/documentation/#link-list-of-built-in-validation-methods for built-in rules.

Example:

<p><label>Email: <input type="text" name="email" id="email" data-rule-email="true" required></label></p>
<p><label>Confirm Email: <input type="text" name="email" id="email_confirm" data-rule-email="true" data-rule-equalTo="#email" required></label></p>

Note the data-rule-* attributes.

I've backported the three Material Design progress drawables to Android 4.0, which can be used as a drop-in replacement for regular ProgressBar, with exactly the same appearance.

These drawables also backported the tinting APIs (and RTL support), and uses ?colorControlActivated as the default tint. A MaterialProgressBar widget which extends ProgressBar has also been introduced for convenience.

This project has also been adopted by afollestad/material-dialogs for progress dialog.

On Android 4.4.4:

On Android 5.1.1:

Riffing on @Mark answer above, added the @updateusage='true' to force the latest size stats (https://msdn.microsoft.com/en-us/library/ms188776.aspx):

        SET NOCOUNT ON
        DECLARE @TableInfo TABLE (tablename varchar(255), rowcounts int, reserved varchar(255), DATA varchar(255), index_size varchar(255), unused varchar(255))
        DECLARE @cmd1 varchar(500)
        SET @cmd1 = 'exec sp_spaceused @objname =''?'', @updateusage =''true'' '

        INSERT INTO @TableInfo (tablename,rowcounts,reserved,DATA,index_size,unused)
        EXEC sp_msforeachtable @command1=@cmd1 
SELECT * FROM @TableInfo ORDER BY Convert(int,Replace(DATA,' KB','')) DESC

Maybe if you're constantly listening to OnMouseOver in the body tag, then callback when the event is not ocurring, but, as Zack states, this could be very ugly, because not all the browsers handle events the same way, there is even some possibility that you lose the MouseOver even by being over a div in the same page.

I want to add my 2 cents. I am far from being a database expert, but I've recently read up a bit on this topic; enough for me to try and give an ELI5. So, here's may layman's explanation.

I understand it as such that an index is like a mini-mirror of your table, pretty much like an associative array. If you feed it with a matching key then you can just jump to that row in one "command".

But if you didn't have that index / array, the query interpreter must use a for-loop to go through all rows and check for a match (the full-table scan).

Having an index has the "downside" of extra storage (for that mini-mirror), in exchange for the "upside" of looking up content faster.

Note that (in dependence of your db engine) creating primary, foreign or unique keys automatically sets up a respective index as well. That same principle is basically why and how those keys work.

The iPhone/iPad simulator that comes with Xcode includes Safari. If you run Safari in the simulator, you can view your website and it should appear the same as it would on a real device. This may work for general layout testing. But since it is a simulator, it is possible that not every single bit of functionality will be exactly the same as using a real iOS device.

If you are writing a website and you need to verify that it looks proper on a given device, then you need to test your website on that actual device. Testing with real hardware is part of the price of doing business.

And yes, you need a Mac to run Xcode.

If am not wrong

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
   //You may decide to prompt to user
   //else just kill
   Process.GetCurrentProcess().Kill();
} 

I had the same problem as deke. I forgot to include the most important script: angular.js :)

<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>

the best solution is to use alias:

alias [yourapp]-mysql="mysql -u root -psomepassword -P3306 -h 127.0.0.1"

example, put this in your script:

alias drupal-mysql="mysql -u root -psomepassword -P3306 -h 127.0.0.1"

then later in your script to load a database:

drupal-mysql database_name < database_dump.sql

to run a statement:

drupal-mysql -e "EXEC SOMESTATEMENT;"

It doesn't work because name is a reserved word in JavaScript. Change the function name to something else.

See http://www.quackit.com/javascript/javascript_reserved_words.cfm

<form id="form" onsubmit="return false;">
    <input style="position:absolute; top:80%; left:5%; width:40%;" type="text" id="userInput" />
    <input style="position:absolute; top:50%; left:5%; width:40%;" type="submit" onclick="othername();" />
</form>

function othername() {
    var input = document.getElementById("userInput").value;
    alert(input);
}

I had a similar issue and wrote a shell script for that reason. I've decided to post it regardless that many good answers were already posted because I think it can be helpful for someone. Feel free to improve it!

numerate

@Gnutt The behavior you want can be achieved by typing the following:

./numerate.sh -d <path to directory> -o modtime -L 4 -b <startnumber> -r

If the option -r is left out the reaming will be only simulated (Should be helpful for testing).

The otion L describes the length of the target number (which will be filled with leading zeros) it is also possible to add a prefix/suffix with the options -p <prefix> -s <suffix>.

In case somebody wants the files to be sorted numerically before they get numbered, just remove the -o modtime option.

I use the following to determine if the string is ascii or unicode:

>> print 'test string'.__class__.__name__
str
>>> print u'test string'.__class__.__name__
unicode
>>> 

Then just use a conditional block to define the function:

def is_ascii(input):
    if input.__class__.__name__ == "str":
        return True
    return False

To align some elements (headerElement) in the center and the last element to the right (headerEnd).

.headerElement {
    margin-right: 5%;
    margin-left: 5%;
}
.headerEnd{
    margin-left: auto;
}

The first solution is also from http://sed.sourceforge.net/sed1line.txt

$ echo -e '1\n2\n2\n3\n3\n3\n4\n4\n4\n4\n5' |sed -nr '$!N;/^(.*)\n\1$/!P;D'
1
2
3

5

the core idea is:

print ONLY once of each duplicate consecutive lines at its LAST appearance and use D command to implement LOOP.

Explains:

1. $!N;: if current line is NOT the last line, use N command to read the next line into pattern space.
2. /^(.*)\n\1$/!P: if the contents of current pattern space is two duplicate string separated by \n, which means the next line is the same with current line, we can NOT print it according to our core idea; otherwise, which means current line is the LAST appearance of all of its duplicate consecutive lines, we can now use P command to print the chars in current pattern space util \n (\n also printed).
3. D: we use D command to delete the chars in current pattern space util \n (\n also deleted), then the content of pattern space is the next line.
4. and D command will force sed to jump to its FIRST command $!N, but NOT read the next line from file or standard input stream.

The second solution is easy to understood (from myself):

$ echo -e '1\n2\n2\n3\n3\n3\n4\n4\n4\n4\n5' |sed -nr 'p;:loop;$!N;s/^(.*)\n\1$/\1/;tloop;D'

the core idea is:

print ONLY once of each duplicate consecutive lines at its FIRST appearance and use : command & t command to implement LOOP.

Explains:

1. read a new line from input stream or file and print it once.
2. use :loop command set a label named loop.
3. use N to read next line into the pattern space.
4. use s/^(.*)\n\1$/\1/ to delete current line if the next line is same with current line, we use s command to do the delete action.
5. if the s command is executed successfully, then use tloop command force sed to jump to the label named loop, which will do the same loop to the next lines util there are no duplicate consecutive lines of the line which is latest printed; otherwise, use D command to delete the line which is the same with thelatest-printed line, and force sed to jump to first command, which is the p command, the content of current pattern space is the next new line.

What am I doing incorrectly?

You have to convert html to javascript object, and then as a second step to json throug JSON.Stringify.

How can I receive a json object in the controller?

View:

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>
<script src="https://raw.githubusercontent.com/marioizquierdo/jquery.serializeJSON/master/jquery.serializejson.js"></script>

var obj = $("#form1").serializeJSON({ useIntKeysAsArrayIndex: true });
$.post("http://localhost:52161/Default/PostRawJson/", { json: JSON.stringify(obj) });

<form id="form1" method="post">
<input name="OrderDate" type="text" /><br />
<input name="Item[0][Id]" type="text" /><br />
<input name="Item[1][Id]" type="text" /><br />
<button id="btn" onclick="btnClick()">Button</button>
</form>

Controller:

public void PostRawJson(string json)
{
    var order = System.Web.Helpers.Json.Decode(json);
    var orderDate = order.OrderDate;
    var secondOrderId = order.Item[1].Id;
}

The 60 you're passing is just the initial capacity for internal storage. It's a hint on how big you think it might be, yet of course it's not limited by that. If you need to preset values you'll have to set them yourself, e.g.:

for (int i = 0; i < 60; i++) {
    list.add(0);
}

I do not like editing the plist directly. You can easily add it to the plist using the GUI:

• Click on the Info.plist in the Navigator on the left.

• Now change the data in the main area:

  • On the last line add the +
  • Enter the name of the group: App Transport Security Settings
  • Right click on the group and select Add Row
  • Enter Allow Arbitrary Loads
  • Set the value on the right to YES

Never construct BigDecimals from floats or doubles. Construct them from ints or strings. floats and doubles loose precision.

This code works as expected (I just changed the type from double to String):

public static void main(String[] args) {
  String doubleVal = "1.745";
  String doubleVal1 = "0.745";
  BigDecimal bdTest = new BigDecimal(  doubleVal);
  BigDecimal bdTest1 = new BigDecimal(  doubleVal1 );
  bdTest = bdTest.setScale(2, BigDecimal.ROUND_HALF_UP);
  bdTest1 = bdTest1.setScale(2, BigDecimal.ROUND_HALF_UP);
  System.out.println("bdTest:"+bdTest); //1.75
  System.out.println("bdTest1:"+bdTest1);//0.75, no problem
}

Try window->show view->devices->view menu->Reset adb and again run application.

I think the following way is more clear and useful for nested ng-repeats. Check it out on Plunker.

The representation of pointers is irrelevant to comparing them, since all comparisons in C take place as values not representations. The only way to compare the representation would be something hideous like:

static const char ptr_rep[sizeof ptr] = { 0 };
if (!memcmp(&ptr, ptr_rep, sizeof ptr)) ...

Add this to your CSS:

ul { list-style-position: inside; }

This will place the li elements in the same indent as other paragraphs and text.

Ref: http://www.w3schools.com/cssref/pr_list-style-position.asp

extension StringProtocol where Index == String.Index {

    func nsRange(of string: String) -> NSRange? {
        guard let range = self.range(of: string) else {  return nil }
        return NSRange(range, in: self)
    }
}

You can programatically change it by setting the system property:

public class App {

    public static void main(String[] args) {

        System.setProperty(org.slf4j.impl.SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "TRACE");

        final org.slf4j.Logger log = LoggerFactory.getLogger(App.class);

        log.trace("trace");
        log.debug("debug");
        log.info("info");
        log.warn("warning");
        log.error("error");

    }
}

The log levels are ERROR > WARN > INFO > DEBUG > TRACE.

Please note that once the logger is created the log level can't be changed. If you need to dynamically change the logging level you might want to use log4j with SLF4J.

Today (2.5 years after this answer) you can safely use Array.forEach. As @ricosrealm suggests, decodeURIComponent was used in this function.

function getJsonFromUrl(url) {
  if(!url) url = location.search;
  var query = url.substr(1);
  var result = {};
  query.split("&").forEach(function(part) {
    var item = part.split("=");
    result[item[0]] = decodeURIComponent(item[1]);
  });
  return result;
}

actually it's not that simple, see the peer-review in the comments, especially:

• hash based routing (@cmfolio)
• array parameters (@user2368055)
• proper use of decodeURIComponent and non-encoded = (@AndrewF)
• non-encoded + (added by me)

For further details, see MDN article and RFC 3986.

Maybe this should go to codereview SE, but here is safer and regexp-free code:

function getJsonFromUrl(url) {
  if(!url) url = location.href;
  var question = url.indexOf("?");
  var hash = url.indexOf("#");
  if(hash==-1 && question==-1) return {};
  if(hash==-1) hash = url.length;
  var query = question==-1 || hash==question+1 ? url.substring(hash) : 
  url.substring(question+1,hash);
  var result = {};
  query.split("&").forEach(function(part) {
    if(!part) return;
    part = part.split("+").join(" "); // replace every + with space, regexp-free version
    var eq = part.indexOf("=");
    var key = eq>-1 ? part.substr(0,eq) : part;
    var val = eq>-1 ? decodeURIComponent(part.substr(eq+1)) : "";
    var from = key.indexOf("[");
    if(from==-1) result[decodeURIComponent(key)] = val;
    else {
      var to = key.indexOf("]",from);
      var index = decodeURIComponent(key.substring(from+1,to));
      key = decodeURIComponent(key.substring(0,from));
      if(!result[key]) result[key] = [];
      if(!index) result[key].push(val);
      else result[key][index] = val;
    }
  });
  return result;
}

This function can parse even URLs like

var url = "?foo%20e[]=a%20a&foo+e[%5Bx%5D]=b&foo e[]=c";
// {"foo e": ["a a",  "c",  "[x]":"b"]}

var obj = getJsonFromUrl(url)["foo e"];
for(var key in obj) { // Array.forEach would skip string keys here
  console.log(key,":",obj[key]);
}
/*
  0 : a a
  1 : c

You can use org.apache.commons.io.IOUtils.copy to copy the contents of the InputStream to a byte array, and then repeatedly read from the byte array using a ByteArrayInputStream. E.g.:

ByteArrayOutputStream baos = new ByteArrayOutputStream();
org.apache.commons.io.IOUtils.copy(in, baos);
byte[] bytes = baos.toByteArray();

// either
while (needToReadAgain) {
    ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
    yourReadMethodHere(bais);
}

// or
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
while (needToReadAgain) {
    bais.reset();
    yourReadMethodHere(bais);
}

I'm not sure what you think this ORDER BY is accomplishing? Even if you do put ORDER BY in the view in a legal way (e.g. by adding a TOP clause), if you just select from the view, e.g. SELECT * FROM dbo.TopUsersTest; without an ORDER BY clause, SQL Server is free to return the rows in the most efficient way, which won't necessarily match the order you expect. This is because ORDER BY is overloaded, in that it tries to serve two purposes: to sort the results and to dictate which rows to include in TOP. In this case, TOP always wins (though depending on the index chosen to scan the data, you might observe that your order is working as expected - but this is just a coincidence).

In order to accomplish what you want, you need to add your ORDER BY clause to the queries that pull data from the view, not to the code of the view itself.

So your view code should just be:

CREATE VIEW [dbo].[TopUsersTest] 
AS 
  SELECT 
    u.[DisplayName], SUM(a.AnswerMark) AS Marks
  FROM
    dbo.Users_Questions AS uq
    INNER JOIN [dbo].[Users] AS u
      ON u.[UserID] = us.[UserID] 
    INNER JOIN [dbo].[Answers] AS a
      ON a.[AnswerID] = uq.[AnswerID]
    GROUP BY u.[DisplayName];

The ORDER BY is meaningless so should not even be included.

To illustrate, using AdventureWorks2012, here is an example:

CREATE VIEW dbo.SillyView
AS
  SELECT TOP 100 PERCENT 
    SalesOrderID, OrderDate, CustomerID , AccountNumber, TotalDue
  FROM Sales.SalesOrderHeader
  ORDER BY CustomerID;
GO

SELECT SalesOrderID, OrderDate, CustomerID, AccountNumber, TotalDue
FROM dbo.SillyView;

Results:

SalesOrderID   OrderDate   CustomerID   AccountNumber   TotalDue
------------   ----------  ----------   --------------  ----------
43659          2005-07-01  29825        10-4020-000676  23153.2339
43660          2005-07-01  29672        10-4020-000117  1457.3288
43661          2005-07-01  29734        10-4020-000442  36865.8012
43662          2005-07-01  29994        10-4020-000227  32474.9324
43663          2005-07-01  29565        10-4020-000510  472.3108

And you can see from the execution plan that the TOP and ORDER BY have been absolutely ignored and optimized away by SQL Server:

There is no TOP operator at all, and no sort. SQL Server has optimized them away completely.

Now, if you change the view to say ORDER BY SalesID, you will then just happen to get the ordering that the view states, but only - as mentioned before - by coincidence.

But if you change your outer query to perform the ORDER BY you wanted:

SELECT SalesOrderID, OrderDate, CustomerID, AccountNumber, TotalDue
FROM dbo.SillyView
ORDER BY CustomerID;

You get the results ordered the way you want:

SalesOrderID   OrderDate   CustomerID   AccountNumber   TotalDue
------------   ----------  ----------   --------------  ----------
43793          2005-07-22  11000        10-4030-011000  3756.989
51522          2007-07-22  11000        10-4030-011000  2587.8769
57418          2007-11-04  11000        10-4030-011000  2770.2682
51493          2007-07-20  11001        10-4030-011001  2674.0227
43767          2005-07-18  11001        10-4030-011001  3729.364

And the plan still has optimized away the TOP/ORDER BY in the view, but a sort is added (at no small cost, mind you) to present the results ordered by CustomerID:

So, moral of the story, do not put ORDER BY in views. Put ORDER BY in the queries that reference them. And if the sorting is expensive, you might consider adding/changing an index to support it.

I personally do not use the objected oriented approach, mostly because it a) only get in the way; b) you will never reuse that as a module.

but something that is not discussed here, is that you must use threading or multiprocessing. Always. otherwise your application will be awful.

just do a simple test: start a window, and then fetch some URL or anything else. changes are your UI will not be updated while the network request is happening. Meaning, your application window will be broken. depend on the OS you are on, but most times, it will not redraw, anything you drag over the window will be plastered on it, until the process is back to the TK mainloop.

Assuming the UTC is not included in the string then:

date_default_timezone_set('America/New_York');
$datestring = '2011-01-01 15:00:00';  //Pulled in from somewhere
$date = date('Y-m-d H:i:s T',strtotime($datestring . ' UTC'));
echo $date;  //Should get '2011-01-01 10:00:00 EST' or something like that

Or you could use the DateTime object.

I got this problem, and tried many ways to solve it. Finally, it turned out that make clean and make again solved it. The reason is: I got the source code together with object files compiled previously with an old gcc version. When my newer gcc version wants to link that old object files, it can't resolve some function in there. It happens to me several times that the source code distributors do not clean up before packing, so a make clean saved the day.

It's not smart to have python code inside java. Wrap your python code with flask or other web framework to make it as a microservice. Make your java program able to call this microservice (e.g. via REST).

Beleive me, this is much simple and will save you tons of issues. And the codes are loosely coupled so they are scalable.

I think you are saying that you have python2 and python3 installed and have added a reference to each version under Pycharm > Settings > Project Interpreter

What I think you are asking is how do you have some projects run with Python 2 and some projects running with Python 3.

If so, you can look under Run > Edit Configurations

I'd answer this question with another question: Do you use singeltons/ Are singeltons bad?

Because (almost all) singelton usage is a glorified global variable.

Additional to Vasil's answer: If you have the values given as a Scala collection, you can write

val list = List(1,2,3,4,5)
val arr = Array[Int](list:_*)
println(arr.mkString)

But usually the toArray method is more handy:

val list = List(1,2,3,4,5)
val arr = list.toArray
println(arr.mkString)

We could use built-in function repr() or string interpolation fr'{}' escape all backwardslashs \ in Python 3.7.*

repr('my_string') or fr'{my_string}'

Keep it simple:

1. cross-domain POST:
   use crossDomain: true,

2. shouldn't refresh the page:
   No, it will not refresh the page as the success or error async callback will be called when the server send back the response.

Example script:

$.ajax({
        type: "POST",
        url: "http://www.yoururl.com/",
        crossDomain: true,
        data: 'param1=value1&param2=value2',
        success: function (data) {
            // do something with server response data
        },
        error: function (err) {
            // handle your error logic here
        }
    });

Range("$A$1").Value = "'01/01/13 00:00" will do it.

Note the single quote; this will defeat automatic conversion to a number type. But is that what you really want? An alternative would be to format the cell to take a date-time value. Then drop the single quote from the string.

simply add to your data structure ( mItems ) , and then notify your adapter about dataset change

private void addItem(String item) {
  mItems.add(item);
  mAdapter.notifyDataSetChanged();
}

addItem("New Item");

Unlike IDs, tags are not used to identify views. Tags are essentially an extra piece of information that can be associated with a view. They are most often used as a convenience to store data related to views in the views themselves rather than by putting them in a separate structure.

Reference: http://developer.android.com/reference/android/view/View.html

You don't need to instantiate the ViewController in Storyboard just to get present() ViewController to work. That's a hackish solution.

If you see a black/blank screen when presenting a VC, it might be because you're calling present() from viewDidLoad() in the First/RootViewController, but the first View isn't ready yet.

Call present() from viewDidAppear to fix this, i.e.:

override func viewDidAppear(_ animated: Bool) {
    super.viewDidAppear(animated)

    let yourVC = YourViewController()
    self.present(yourVC, animated: true, completion: nil)
}

Once any "View" has appeared in your App, you can start calling present() from viewDidLoad().

Using UINavigationController (as suggested in an answer) is another option, but it might be an overkill to solve this issue. You might end up complicating the user flow. Use the UINavigationController based solution only if you want to have a NavigatonBar or want to return to the previous view controller.

try this one

     'Note: In the Regional Project that's coming up we learn how to import data from multiple Excel workbooks

        OpenBook.Close False
        
    End If

Kotlin Extension Solution

Add removeSelf to directly call on a view. If attached to a parent, it will be removed. This makes your code more declarative, and thus readable.

myView.removeSelf()

fun View?.removeSelf() {
    this ?: return
    val parent = parent as? ViewGroup ?: return
    parent.removeView(this)
}

Here are 3 options for how to programmatically add a view to a ViewGroup.

// Built-in
myViewGroup.addView(myView)

// Reverse addition
myView.addTo(myViewGroup)

fun View?.addTo(parent: ViewGroup?) {
    this ?: return
    parent ?: return
    parent.addView(this)
}

// Null-safe extension
fun ViewGroup?.addView(view: View?) {
    this ?: return
    view ?: return
    addView(view)
}

If you support IE, for versions of Internet Explorer 8 and above, this:

<meta http-equiv="X-UA-Compatible" content="IE=9; IE=8; IE=7" />

Forces the browser to render as that particular version's standards. It is not supported for IE7 and below.

If you separate with semi-colon, it sets compatibility levels for different versions. For example:

<meta http-equiv="X-UA-Compatible" content="IE=7; IE=9" />

Renders IE7 and IE8 as IE7, but IE9 as IE9. It allows for different levels of backwards compatibility. In real life, though, you should only chose one of the options:

<meta http-equiv="X-UA-Compatible" content="IE=8" />

This allows for much easier testing and maintenance. Although generally the more useful version of this is using Emulate:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE8" />

For this:

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

It forces the browser the render at whatever the most recent version's standards are.

The flexbox way:

.foo {
    display: flex;
    align-items: center;
    justify-content: center;
    height: 50px;
}

self and $self aren't the same. The former is the object pointed to by "this" and the latter a jQuery object whose "scope" is the object pointed to by "this". Similarly, $body isn't the body DOM element but the jQuery object whose scope is the body element.

I'm not sure if I understand your question correctly. It is a bit unclear. However, what might be confusing you is the following:

1. When passing by reference, a reference to the same object is passed to the function being called. Any changes to the object will be reflected in the original object and hence the caller will see it.

2. When passing by value, the copy constructor will be called. The default copy constructor will only do a shallow copy, hence, if the called function modifies an integer in the object, this will not be seen by the calling function, but if the function changes a data structure pointed to by a pointer within the object, then this will be seen by the caller due to the shallow copy.

I might have mis-understood your question, but I thought I would give it a stab anyway.

Because otherwise scanf will think you are passing a pointer to a float which is a smaller size than a double, and it will return an incorrect value.

int does not allow null, use-

int? value = 0  

or use

Nullable<int> value

For fixing:

No matching client found for package name 'com.example.exampleapp:

You should get a valid google-service.json file for your package from here

For fixing:

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 8.3.0.:

You should move apply plugin: 'com.google.gms.google-services' to the end of your app gradle.build file. Something like this:

dependencies {
    ...
}
apply plugin: 'com.google.gms.google-services'

I think you're using the CodeIgniter URI routing wrong: http://ellislab.com/codeigniter%20/user-guide/general/routing.html

Basically if you had a Products_controller with a method called delete($id) and the url you created was of the form http://localhost/designs2/index.php/products_controller/delete/4, the delete function would receive the $id as a parameter.

Using what you have there I think you can get the id by using $this->input->get('product_id);

You should always use below MIME type if you want to serve excel file in xlsx format

application/vnd.openxmlformats-officedocument.spreadsheetml.sheet 

list all the other cpp files after main.cpp.

ie

g++ main.cpp other.cpp etc.cpp

and so on.

Or you can compile them all individually. You then link all the resulting ".o" files together.

try

amtf =  amtf.Insert(amtf.Length - 2, ".");

we can even write like this by creating a new String object in the class and assigning it what ever we want in constructor and return that in toString method which is overridden

public class Student{  
 int id;  
 String name;  
 String address;  
 String details;
 Student(int id, String name, String address){  
 this.id=id;  
 this.name=name;  
 this.address=address;  
 this.details=id+"  "+name+"  "+address;  
 }  

//overriding the toString() method  
public String toString(){ 
  return details;  
 }  
 public static void main(String args[]){  
   Student s1=new Student(100,"Joe","success");  
   Student s2=new Student(50,"Jeff","fail");  

   System.out.println(s1);//compiler writes here s1.toString()  
   System.out.println(s2);//compiler writes here s2.toString()  
 }  
}

there might be the situation your machine is managed by Puppet or so. Then changing root .profile or .bash_rc file does not work at all. Therefore you could add the following to your .profile file. After that you can use "mydo" instead of "sudo". It works perfectly for me.

function mydo() {
    echo Executing sudo with: "$1" "${@:2}"
    sudo $(which $1) "${@:2}"
}

I used PHP Version 5.5.32.

Here is the simplest solution I can think of:

let rec distribute e = function
  | [] -> [[e]]
  | x::xs' as xs -> (e::xs)::[for xs in distribute e xs' -> x::xs]

let permute xs = Seq.fold (fun ps x -> List.collect (distribute x) ps) [[]] xs

The distribute function takes a new element e and an n-element list and returns a list of n+1 lists each of which has e inserted at a different place. For example, inserting 10 at each of the four possible places in the list [1;2;3]:

> distribute 10 [1..3];;
val it : int list list =
  [[10; 1; 2; 3]; [1; 10; 2; 3]; [1; 2; 10; 3]; [1; 2; 3; 10]]

The permute function folds over each element in turn distributing over the permutations accumulated so far, culminating in all permutations. For example, the 6 permutations of the list [1;2;3]:

> permute [1;2;3];;
val it : int list list =
  [[3; 2; 1]; [2; 3; 1]; [2; 1; 3]; [3; 1; 2]; [1; 3; 2]; [1; 2; 3]]

Changing the fold to a scan in order to keep the intermediate accumulators sheds some light on how the permutations are generated an element at a time:

> Seq.scan (fun ps x -> List.collect (distribute x) ps) [[]] [1..3];;
val it : seq<int list list> =
  seq
    [[[]]; [[1]]; [[2; 1]; [1; 2]];
     [[3; 2; 1]; [2; 3; 1]; [2; 1; 3]; [3; 1; 2]; [1; 3; 2]; [1; 2; 3]]]

Sure, just add & after the command:

read_cfg cfgA &
read_cfg cfgB &
read_cfg cfgC &
wait

all those jobs will then run in the background simultaneously. The optional wait command will then wait for all the jobs to finish.

Each command will run in a separate process, so it's technically not "multithreading", but I believe it solves your problem.

Since you're using Spring, stick with Spring, don't hack it yourself like the other post posits.

The Spring manual says:

You shouldn't interact directly with the HttpSession for security purposes. There is simply no justification for doing so - always use the SecurityContextHolder instead.

The suggested best practice for accessing the session is:

Object principal = SecurityContextHolder.getContext().getAuthentication().getPrincipal();

if (principal instanceof UserDetails) {
  String username = ((UserDetails)principal).getUsername();
} else {
  String username = principal.toString();
}

The key here is that Spring and Spring Security do all sorts of great stuff for you like Session Fixation Prevention. These things assume that you're using the Spring framework as it was designed to be used. So, in your servlet, make it context aware and access the session like the above example.

If you just need to stash some data in the session scope, try creating some session scoped bean like this example and let autowire do its magic. :)

I think with

System.getProperty("os.name"); 

Checking the operating system on can manage the shell/bash scrips if such are supported. if there is need to make the code portable.

I am very suprised nobody came up with this kind of solution to bind it against bool array. It might not be the cleanest, but it can be used very easily:

private bool[] _modeArray = new bool[] { true, false, false};
public bool[] ModeArray
{
    get { return _modeArray ; }
}
public int SelectedMode
{
    get { return Array.IndexOf(_modeArray, true); }
}

in XAML:

<RadioButton GroupName="Mode" IsChecked="{Binding Path=ModeArray[0], Mode=TwoWay}"/>
<RadioButton GroupName="Mode" IsChecked="{Binding Path=ModeArray[1], Mode=TwoWay}"/>
<RadioButton GroupName="Mode" IsChecked="{Binding Path=ModeArray[2], Mode=TwoWay}"/>

NOTE: you dont need two-way binding if you dont want to one checked by default. TwoWay binding is the biggest cons of this solution.

Pros:

• No need for code behind
• No need for extra class (IValue Converter)
• No Need for extra enums
• doesnt require bizzare binding
• straightforward and easy to understand
• doesnt violate MVVM (heh, at least I hope so)

Your current solution is best - comment out the parameter name if you don't use it. That applies to all compilers, so you don't have to use the pre-processor to do it specially for GCC.

Sorry, didn't quite get your question. So something like this?

str.ToCharArray().Any(char.IsDigit);

Or does the value have to be an integer completely, without any additional strings?

if(str.ToCharArray().All(char.IsDigit(c));

Quick and dirty way:

System.out.println("I'm in line #" + 
    new Exception().getStackTrace()[0].getLineNumber());

With some more details:

StackTraceElement l = new Exception().getStackTrace()[0];
System.out.println(
    l.getClassName()+"/"+l.getMethodName()+":"+l.getLineNumber());

That will output something like this:

com.example.mytest.MyClass/myMethod:103

System.out.print("Enter a Value: ");
val = s.nextInt();

This line is placed in last.The whole code is as follows:-

public static void main(String[] args){
    int min, max;

    Scanner s = new Scanner(System.in);
    System.out.print("Enter a Value: ");
    int val = s.nextInt();
    min = max = val;

    while (val != 0) {
        if (val < min) {
            min = val;
        }
        if (val > max) {
            max = val;
        }
        System.out.print("Enter a Value: ");
        val = s.nextInt();

    }
    System.out.println("Min: " + min);
    System.out.println("Max: " + max);
}

@bku_drytt's solution didn't do it for me.

I solved it by additionally changing every occurence of 14.0 to 12.0 and v140 to v120 manually in the .vcxproj files.

Then it compiled!

You will also get 'root element is missing' when the BOM strikes :). BOM = byte order mark. This is an extra character that gets added to the start of a file when it is saved with the wrong encoding.
This can happen sometimes in Visual Studio when working with XML files. You can either code something to remove it from all your files, or if you know which file it is you can force visual studio to save it with a specific encoding (utf-8 or ascii IIRC).

If you open the file in an editor other than VS (try notepad++), you will see two funny characters before the <? xml declaration.

To fix this in VS, open the file in VS and then depending on the version of VS

• File > Advanced Save Options > choose an appropriate encoding
• File > Save As > keep the filename, click the drop-down arrow on the right side of the save button to select an encoding

Do you mean include javascript variable values in the query string of the URL?

Yes:

 window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat="+var1+"&lon="+var2+"&setLatLon="+varEtc;

If your jenkins is running as service instead of process you should stop it first using

sudo service jenkins stop

After stopping it you can follow the normal flow of removing it using commands respective to your linux flavour

For centos it will be

sudo yum remove jenkins

For ubuntu it will

sudo apt-get remove --purge jenkins

I hope this will solve your issue.

Depending on your needs, you can probably rely on node's path module.

You may not be able to hit the filesystem (e.g. the file hasn't been created yet) and tbh you probably want to avoid hitting the filesystem unless you really need the extra validation. If you can make the assumption that what you are checking for follows .<extname> format, just look at the name.

Obviously if you are looking for a file without an extname you will need to hit the filesystem to be sure. But keep it simple until you need more complicated.

const path = require('path');

function isFile(pathItem) {
  return !!path.extname(pathItem);
}

The idea of mapping an function to array of data comes from functional programming. You shouldn't think about array_map as a foreach loop that calls a function on each element of the array (even though that's how it's implemented). It should be thought of as applying the function to each element in the array independently.

In theory such things as function mapping can be done in parallel since the function being applied to the data should ONLY affect the data and NOT the global state. This is because an array_map could choose any order in which to apply the function to the items in (even though in PHP it doesn't).

array_walk on the other hand it the exact opposite approach to handling arrays of data. Instead of handling each item separately, it uses a state (&$userdata) and can edit the item in place (much like a foreach loop). Since each time an item has the $funcname applied to it, it could change the global state of the program and therefor requires a single correct way of processing the items.

Back in PHP land, array_map and array_walk are almost identical except array_walk gives you more control over the iteration of data and is normally used to "change" the data in-place vs returning a new "changed" array.

array_filter is really an application of array_walk (or array_reduce) and it more-or-less just provided for convenience.

A lot of good answers but why not just use JSON.stringify(your_variable) ? Then take the contents via copy and paste (remove outer quotes). I posted this same answer also at: How to save the output of a console.log(object) to a file?

You need to use the Spring JUnit runner in order to wire in Spring beans from your context. The code below assumes that you have a application context called testContest.xml available on the test classpath.

import org.hibernate.SessionFactory;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.transaction.annotation.Transactional;

import java.sql.SQLException;

import static org.hamcrest.MatcherAssert.assertThat;
import static org.hamcrest.Matchers.startsWith;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath*:**/testContext.xml"})
@Transactional
public class someDaoTest {

    @Autowired
    protected SessionFactory sessionFactory;

    @Test
    public void testDBSourceIsCorrect() throws SQLException {
        String databaseProductName = sessionFactory.getCurrentSession()
                .connection()
                .getMetaData()
                .getDatabaseProductName();
        assertThat("Test container is pointing at the wrong DB.", databaseProductName, startsWith("HSQL"));
    }
}

Note: This works with Spring 2.5.2 and Hibernate 3.6.5

If you want to skip current iteration, use continue;.

for(int i = 0; i < 5; i++){
    if (i == 2){
        continue;
    }
 }

Need to break out of the whole loop? Use break;

for(int i = 0; i < 5; i++){
    if (i == 2){
        break;
    }
}

If you need to break out of more than one loop use break someLabel;

outerLoop:                                           // Label the loop
for(int j = 0; j < 5; j++){
     for(int i = 0; i < 5; i++){
        if (i==2){
          break outerLoop;
        }
     }
  }

*Note that in this case you are not marking a point in code to jump to, you are labeling the loop! So after the break the code will continue right after the loop!

When you need to skip one iteration in nested loops use continue someLabel;, but you can also combine them all.

outerLoop:
for(int j = 0; j < 10; j++){
     innerLoop:
     for(int i = 0; i < 10; i++){
        if (i + j == 2){
          continue innerLoop;
        }
        if (i + j == 4){
          continue outerLoop;
        }
        if (i + j == 6){
          break innerLoop;
        }
        if (i + j == 8){
          break outerLoop;
        }
     }
  }

this can be achieved using below...

 List<String> unavailable = list1.stream()
                            .filter(e -> !list2.contains(e))
                            .collect(Collectors.toList());

I'll add a map and filter version because why not.

sum(map(lambda x:x>5, j))
sum(1 for _ in filter(lambda x:x>5, j))

Use document.location.href to change the page location, place it in the function on a successful ajax run.

Running the command prompt or Powershell ISE as an administrator fixed this for me.

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

This solution worked for me:

just add another class into your table element: w-100 d-block d-md-table

so it would be : <table class="table table-responsive w-100 d-block d-md-table">

for bootstrap 4 w-100 set the width to 100% d-block (display: block) and d-md-table (display: table on min-width: 576px)

Bootstrap 4 display docs

You can also use unlist(), which is often useful for handling lists:

> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))

> mylist
$A
[1] 1 2 3

$B
[1] 4 5 6

$C
[1] 7 8 9

> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3 
 1  2  3  4  5  6  7  8  9 

> length(unlist(mylist))
[1] 9

unlist() is a simple way of executing other functions on lists as well, such as:

> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument

> sum(unlist(mylist))
[1] 45

Try the Apache Commons HttpClient library instead of trying to roll your own: http://hc.apache.org/httpclient-3.x/index.html

From their sample code:

  HttpClient httpclient = new HttpClient();
  httpclient.getHostConfiguration().setProxy("myproxyhost", 8080);

  /* Optional if authentication is required.
  httpclient.getState().setProxyCredentials("my-proxy-realm", " myproxyhost",
   new UsernamePasswordCredentials("my-proxy-username", "my-proxy-password"));
  */

  PostMethod post = new PostMethod("https://someurl");
  NameValuePair[] data = {
     new NameValuePair("user", "joe"),
     new NameValuePair("password", "bloggs")
  };
  post.setRequestBody(data);
  // execute method and handle any error responses.
  // ...
  InputStream in = post.getResponseBodyAsStream();
  // handle response.


  /* Example for a GET reqeust
  GetMethod httpget = new GetMethod("https://someurl");
  try { 
    httpclient.executeMethod(httpget);
    System.out.println(httpget.getStatusLine());
  } finally {
    httpget.releaseConnection();
  }
  */

Try this

var store = dtpDateTimePicker.Value.Date;

store can be anything entity object etc.

I'm using Laravel 5.7 and tried all of the above answers but nothing seemed to be hitting the spot.

For me, it was a rather simple fix by removing the cache files created by Laravel.
It seemed that my changes were not being reflected, and therefore my application wasn't seeing the routes.

A bit overkill, but I decided to reset all my cache at the same time using the following commands:

php artisan route:clear
php artisan view:clear
php artisan cache:clear

The main one here is the first command which will delete the bootstrap/cache/routes.php file.
The second command will remove the cached files for the views that are stored in the storage/framework/cache folder.
Finally, the last command will clear the application cache.

You can specify gradients for colours in certain circumstances in CSS3, and of course borders can be set to a colour, so you should be able to use a gradient as a border colour. This would include the option of specifying a transparent colour, which means you should be able to achieve the effect you're after.

However, I've never seen it used, and I don't know how well supported it is by current browsers. You'll certainly need to accept that at least some of your users won't be able to see it.

A quick google turned up these two pages which should help you on your way:

• CSS3 Gradient Borders
• http://designshack.co.uk/tutorials/introduction-to-css3-part-2-borders

Hope that helps.

Unicode or other character set characters falling through?

I have seen similar "strange" characters show up on sites I have worked on often when the text is copied from an email or some other document format (e.g. word) into a text editor. The editor can display the non ASCII characters but the browser can't. For the website, I would suggest looking up the HTML entity code for the character and inserting that instead ... or switch to more standard ones.

From the @param wiki page:

Parameters With Properties

If a parameter is expected to have a particular property, you can document that immediately after the @param tag for that parameter, like so:

 /**
  * @param userInfo Information about the user.
  * @param userInfo.name The name of the user.
  * @param userInfo.email The email of the user.
  */
 function logIn(userInfo) {
        doLogIn(userInfo.name, userInfo.email);
 }

There used to be a @config tag which immediately followed the corresponding @param, but it appears to have been deprecated (example here).

This is one of the simplest ways to sort record by Date:

SELECT  `Article_Id` ,  `Title` ,  `Source_Link` ,  `Content` ,  `Source` , `Reg_Date`, UNIX_TIMESTAMP(  `Reg_Date` ) AS DATE
FROM article
ORDER BY DATE DESC 

Perhaps this complementary example of "match" would be helpful.

Having two datasets:

first_dataset <- data.frame(name = c("John", "Luke", "Simon", "Gregory", "Mary"),
                            role = c("Audit", "HR", "Accountant", "Mechanic", "Engineer"))

second_dataset <- data.frame(name = c("Mary", "Gregory", "Luke", "Simon"))

If the name column contains only unique across collection values (across whole collection) then you can access row in other dataset by value of index returned by match

name_mapping <- match(second_dataset$name, first_dataset$name)

match returns proper row indexes of names in first_dataset from given names from second: 5 4 2 1 example here - accesing roles from first dataset by row index (by given name value)

for(i in 1:length(name_mapping)) {
    role <- as.character(first_dataset$role[name_mapping[i]])   
    second_dataset$role[i] = role
}

===

second dataset with new column:
     name       role
1    Mary   Engineer
2 Gregory   Mechanic
3    Luke Supervisor
4   Simon Accountant

Another way is to use TRANSLATE:

TRANSLATE (col_name, 'x'||CHR(10)||CHR(13), 'x')

The 'x' is any character that you don't want translated to null, because TRANSLATE doesn't work right if the 3rd parameter is null.

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

I found simple solution, which works fine even if you want add new fragments in the middle or replace current fragment. In my solution you should override getItemId() which should return unique id for each fragment. Not position as by default.

There is it:

public class DynamicPagerAdapter extends FragmentPagerAdapter {

private ArrayList<Page> mPages = new ArrayList<Page>();
private ArrayList<Fragment> mFragments = new ArrayList<Fragment>();

public DynamicPagerAdapter(FragmentManager fm) {
    super(fm);
}

public void replacePage(int position, Page page) {
    mPages.set(position, page);
    notifyDataSetChanged();
}

public void setPages(ArrayList<Page> pages) {
    mPages = pages;
    notifyDataSetChanged();
}

@Override
public Fragment getItem(int position) {
    if (mPages.get(position).mPageType == PageType.FIRST) {
        return FirstFragment.newInstance(mPages.get(position));
    } else {
        return SecondFragment.newInstance(mPages.get(position));
    }
}

@Override
public int getCount() {
    return mPages.size();
}

@Override
public long getItemId(int position) {
    // return unique id
    return mPages.get(position).getId();
}

@Override
public Object instantiateItem(ViewGroup container, int position) {
    Fragment fragment = (Fragment) super.instantiateItem(container, position);
    while (mFragments.size() <= position) {
        mFragments.add(null);
    }
    mFragments.set(position, fragment);
    return fragment;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    super.destroyItem(container, position, object);
    mFragments.set(position, null);
}

@Override
public int getItemPosition(Object object) {
    PagerFragment pagerFragment = (PagerFragment) object;
    Page page = pagerFragment.getPage();
    int position = mFragments.indexOf(pagerFragment);
    if (page.equals(mPages.get(position))) {
        return POSITION_UNCHANGED;
    } else {
        return POSITION_NONE;
    }
}
}

Notice: In this example FirstFragment and SecondFragment extends abstract class PageFragment, which has method getPage().

You can use ANSI escape sequences to do this on the console. I know this works on Linux and OSX, I'm not sure if the Windows console (cmd) supports ANSI.

You need to use web services. In the above code I have php web service to be used which has a callback function which is optional. Assuming you know HTML5 I did not post the html code. In the url you can send the details to the web server.

Here are a few simple examples to see the difference in action:

See the list of numbers here:

nums = [1, 9, -3, 4, 8, 5, 7, 14]

When calling sorted on this list, sorted will make a copy of the list. (Meaning your original list will remain unchanged.)

Let's see.

sorted(nums)

returns

[-3, 1, 4, 5, 7, 8, 9, 14]

Looking at the nums again

nums

We see the original list (unaltered and NOT sorted.). sorted did not change the original list

[1, 2, -3, 4, 8, 5, 7, 14]

Taking the same nums list and applying the sort function on it, will change the actual list.

Let's see.

Starting with our nums list to make sure, the content is still the same.

nums

[-3, 1, 4, 5, 7, 8, 9, 14]

nums.sort()

Now the original nums list is changed and looking at nums we see our original list has changed and is now sorted.

nums
[-3, 1, 2, 4, 5, 7, 8, 14]

Command-Option-Shift-K should do it. Alternatively, go to product menu, press the option key, now the option "Clean" will change to "Clean Build Folder ..." select that option.

@mikepenz has the right one.

You could just hit SHIFT+COMMAND+A (if you're using OSX and 1.4 android studio) and enter OFFLINE in the search box.

Then you'll see what mike have shown you.

Just deselect offline.

The ideal datatype for storing Lat Long values in SQL Server is decimal(9,6)

As others have said, this is at approximately 10cm precision, whilst only using 5 bytes of storage.

e.g. CAST(123.456789 as decimal(9,6)) as [LatOrLong]

Yes it is possible in theory as defined by the specification. However there is no practical implementation as yet that would allow this.

Refer: NFC Forum Connection Handover Technical Specification http://www.nfc-forum.org/specs/spec_list/

Quoting from the specification regarding the security - "The Handover Protocol requires transmission of network access data and credentials (the carrier configuration data) to allow one device to connect to a wireless network provided by another device. Because of the close proximity needed for communication between NFC Devices and Tags, eavesdropping of carrier configuration data is difficult, but not impossible, without recognition by the legitimate owner of the devices. Transmission of carrier configuration data to devices that can be brought to close proximity is deemed legitimate within the scope of this specification."

I create HashMaps in bash 3 using dynamic variables. I explained how that works in my answer to: Associative arrays in Shell scripts

Also you can take a look in shell_map, which is a HashMap implementation made in bash 3.

You have no shell at /bin/sh? Have you tried docker run -it pensu/busybox /usr/bin/sh ?

If your vectors are sorted*, check out set_union from <algorithm>.

set_union(A.begin(), A.end(), B.begin(), B.end(), AB.begin());

There's a more thorough example in the link

You don't mention if this is a GUI program or not, but most GUI packages include a way to capture and handle keyboard input. For example, with tkinter (in Py3), you can bind to a certain event and then handle it in a function. For example:

import tkinter as tk

def key_handler(event=None):
    if event and event.keysym in ('s', 'p'):
        'do something'

r = tk.Tk()
t = tk.Text()
t.pack()
r.bind('<Key>', key_handler)
r.mainloop()

With the above, when you type into the Text widget, the key_handler routine gets called for each (or almost each) key you press.

You can use context manager to run the faulty function and assert it raises the exception with a certain message using assertRaisesMessage

with self.assertRaisesMessage(SomeException,'Some error message e.g 404 Not Found'):
    faulty_funtion()

For capital letters:

i=67
letters=({A..Z})
echo "${letters[$i-65]}"

Output:

C

onreadystatechange Stores a function (or the name of a function) to be called automatically each time the readyState property changes readyState Holds the status of the XMLHttpRequest. Changes from 0 to 4:

0: request not initialized

1: server connection established

2: request received

3: processing request

4: request finished and response is ready

status 200: "OK"

404: Page not found

My answer to a similar question: https://stackoverflow.com/a/27141956/435766 I personally prefer going down the category road on that one, since I want to be able to use it on any subclass of UIView.

i want to show records only starting with b

select name from user where name LIKE 'b%';

i am trying to sort MySQL data alphabeticaly

select name from user ORDER BY name;

i am trying to sort MySQL data in reverse alphabetic order

select name from user ORDER BY name desc;

In summary, two ways were introduced

1) using order by DBMS_RANDOM.VALUE clause
2) using sample([%]) function

The first way has advantage in 'CORRECTNESS' which means you will never fail get result if it actually exists, while in the second way you may get no result even though it has cases satisfying the query condition since information is reduced during sampling.

The second way has advantage in 'EFFICIENT' which mean you will get result faster and give light load to your database. I was given an warning from DBA that my query using the first way gives loads to the database

You can choose one of two ways according to your interest!

As @jeff-dickey suggested, in the root of your project, make a folder called test. In that folder, make a file called mocha.opts. Now where I try to improve on Jeff's answer, what worked for me was instead of specifying the name of just one test folder, I specified a pattern to find all tests to run in my project by adding this line:

*/tests/*.js --recursive in mocha.opts

If you instead want to specify the exact folders to look for tests in, I did something like this:

shared/tests/*.js --recursive
server/tests/graph/*.js --recursive

I hope this helps anyone who needed more than what the other answers provide

Here are the complete list of scripts required to get rid of this problem. (Make sure the file exists at the given file path)

   <script src="@Url.Content("~/Scripts/jquery-1.8.2.js")" type="text/javascript">
    </script>
    <script src="@Url.Content("~/Scripts/jquery-ui-1.8.24.js")" type="text/javascript">
    </script>
    <script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript">
    </script>
    <script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript">
    </script>
    <script src="@Url.Content("~/Scripts/jquery.unobtrusive-ajax.js")" type="text/javascript">
    </script>

and also include the below css link in _Layout.cshtml for a stylish popup.

<link rel="stylesheet" type="text/css" href="../../Content/themes/base/jquery-ui.css" />

I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader's fault. Try measuring this:

InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing

I think you'll find it's almost exactly the same time as when you're parsing the text.

Note that you should also give InputStreamReader an appropriate encoding - the platform default encoding is almost certainly not what you should be using.

If istream fails to insert, it will set the fail bit.

int i = 0;
std::cin >> i; // type a and press enter
if (std::cin.fail())
{
    std::cout << "I failed, try again ..." << std::endl
    std::cin.clear(); // reset the failed state
}

You can set this up in a do-while loop to get the correct type (int in this case) propertly inserted.

Adding the above line to sourceSets in build.gradle file worked. Nothing else worked whatsoever.

If android version is Kitkat or above, users can change default sms application. This method will get default sms app and start default sms app.

private void sendSMS() {    
      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) // At least KitKat
      {
         String defaultSmsPackageName = Telephony.Sms.getDefaultSmsPackage(this); // Need to change the build to API 19

         Intent sendIntent = new Intent(Intent.ACTION_SEND);
         sendIntent.setType("text/plain");
         sendIntent.putExtra(Intent.EXTRA_TEXT, "text");

         if (defaultSmsPackageName != null)// Can be null in case that there is no default, then the user would be able to choose
         // any app that support this intent.
         {
            sendIntent.setPackage(defaultSmsPackageName);
         }
         startActivity(sendIntent);

      }
      else // For early versions, do what worked for you before.
      {
         Intent smsIntent = new Intent(android.content.Intent.ACTION_VIEW);
         smsIntent.setType("vnd.android-dir/mms-sms");
         smsIntent.putExtra("address","phoneNumber");         
         smsIntent.putExtra("sms_body","message");
         startActivity(smsIntent);
      }
   }

grep "$(printf '\t')" worked for me on Mac OS X

String stringWithQuates = "\""+ "your,comma,separated,string" + "\"";

this will retain the comma in CSV file

Please check the class you inherited. Whether it is simply Controller or APIController.

By mistake we might create a controller from MVC 5 controller. It should be from Web API Controller.

"BypassTraverseChecking" means that you can directly access any deep-level subdirectory even if you don't have all the intermediary access privileges to directories in between, i.e. all directories above it towards root level .

Maybe in this way?

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

Setting environment variable TZ should also works

ex: export TZ=Asia/Shanghai

Sven has shown how to use the class gaussian_kde from Scipy, but you will notice that it doesn't look quite like what you generated with R. This is because gaussian_kde tries to infer the bandwidth automatically. You can play with the bandwidth in a way by changing the function covariance_factor of the gaussian_kde class. First, here is what you get without changing that function:

However, if I use the following code:

import matplotlib.pyplot as plt
import numpy as np
from scipy.stats import gaussian_kde
data = [1.5]*7 + [2.5]*2 + [3.5]*8 + [4.5]*3 + [5.5]*1 + [6.5]*8
density = gaussian_kde(data)
xs = np.linspace(0,8,200)
density.covariance_factor = lambda : .25
density._compute_covariance()
plt.plot(xs,density(xs))
plt.show()

I get

which is pretty close to what you are getting from R. What have I done? gaussian_kde uses a changable function, covariance_factor to calculate its bandwidth. Before changing the function, the value returned by covariance_factor for this data was about .5. Lowering this lowered the bandwidth. I had to call _compute_covariance after changing that function so that all of the factors would be calculated correctly. It isn't an exact correspondence with the bw parameter from R, but hopefully it helps you get in the right direction.
