basically hidden fields will be more useful and advantages to use with multi step form. we can use hidden fields to pass one step information to next step using hidden and keep it forwarding till the end step.

1. CSRF tokens.

Cross-site request forgery is a very common website vulnerability. Requiring a secret, user-specific token in all form submissions will prevent CSRF attacks since attack sites cannot guess what the proper token is and any form submissions they perform on the behalf of the user will always fail.

2. Save state in multi-page forms.

If you need to store what step in a multi-page form the user is currently on, use hidden input fields. The user doesn't need to see this information, so hide it in a hidden input field.

General rule: Use the field to store anything that the user doesn't need to see, but that you want to send to the server on form submission.

While the NIST recommendation PBKDF2 has already been mentioned, I'd like to point out that there was a public password hashing competition that ran from 2013 to 2015. In the end, Argon2 was chosen as the recommended password hashing function.

There is a fairly well adopted Java binding for the original (native C) library that you can use.

In the average use-case, I don't think it does matter from a security perspective if you choose PBKDF2 over Argon2 or vice-versa. If you have strong security requirements, I recommend considering Argon2 in your evaluation.

For further information on the security of password hashing functions see security.se.

Check that you are extending CI_Controller class in your controller and in the view you have to echo base_url($path) function, otherwise it will not work.

The ifelse function would be a quick and easy way to do this.

I suppose you want to find 'simple' paths (a path is simple if no node appears in it more than once, except maybe the 1st and the last one).

Since the problem is NP-hard, you might want to do a variant of depth-first search.

Basically, generate all possible paths from A and check whether they end up in G.

I've found a temporary solution that will at least let me process this job. I wrote a short AutoIt script that waits for the "Update Links" window to appear, then clicks the "Don't Update" button. Code is as follows:

while 1
if winexists("Microsoft Excel","This workbook contains links to other data sources.") Then
   controlclick("Microsoft Excel","This workbook contains links to other data sources.",2)
EndIf
WEnd

So far this seems to be working. I'd really like to find a solution that's entirely VBA, however, so that I can make this a standalone application.

You can now do this without a third party library or a widget. It's built into TextView in API level 26. Add android:autoSizeTextType="uniform" to your TextView and set height to it. That's all. Use app:autoSizeTextType="uniform" for backward compatibility

https://developer.android.com/guide/topics/ui/look-and-feel/autosizing-textview.html

<?xml version="1.0" encoding="utf-8"?>
<TextView
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:autoSizeTextType="uniform" />

You can also use TextViewCompat for compatibility.

This actually removes the contents from the list, but doesn't replace the old label with a new empty list:

del lst[:]

Here's an example:

lst1 = [1, 2, 3]
lst2 = lst1
del lst1[:]
print(lst2)

For the sake of completeness, the slice assignment has the same effect:

lst[:] = []

It can also be used to shrink a part of the list while replacing a part at the same time (but that is out of the scope of the question).

Note that doing lst = [] does not empty the list, just creates a new object and binds it to the variable lst, but the old list will still have the same elements, and effect will be apparent if it had other variable bindings.

For a ridiculously large and probably redundant version, try a lot of for loops.

string stringlist[10];
int count = 0;

for (int i = 0; i < sequence.length(); i++)
{
    if (sequence[i] == ' ')
    {
        stringlist[count] = sequence.substr(0, i);
        sequence.erase(0, i+1);
        i = 0;
        count++;
    }
    else if (i == sequence.length()-1)  // Last word
    {
        stringlist[count] = sequence.substr(0, i+1);
    }
}

It isn't pretty, but by and large (Barring punctuation and a slew of other bugs) it works!

• Approach 1 - transform translateX/translateY:

  Example Here / Full Screen Example

  In supported browsers (most of them), you can use top: 50%/left: 50% in combination with translateX(-50%) translateY(-50%) to dynamically vertically/horizontally center the element.

.container {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 50%;_x000D_
    -moz-transform: translateX(-50%) translateY(-50%);_x000D_
    -webkit-transform: translateX(-50%) translateY(-50%);_x000D_
    transform: translateX(-50%) translateY(-50%);_x000D_
}

<div class="container">_x000D_
    <span>I'm vertically/horizontally centered!</span>_x000D_
</div>

• Approach 2 - Flexbox method:

  Example Here / Full Screen Example

  In supported browsers, set the display of the targeted element to flex and use align-items: center for vertical centering and justify-content: center for horizontal centering. Just don't forget to add vendor prefixes for additional browser support (see example).

html, body, .container {_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.container {_x000D_
    display: -webkit-flexbox;_x000D_
    display: -ms-flexbox;_x000D_
    display: -webkit-flex;_x000D_
    display: flex;_x000D_
    -webkit-flex-align: center;_x000D_
    -ms-flex-align: center;_x000D_
    -webkit-align-items: center;_x000D_
    align-items: center;_x000D_
    justify-content: center;_x000D_
}

<div class="container"> _x000D_
  <span>I'm vertically/horizontally centered!</span>_x000D_
</div>

• Approach 3 - table-cell/vertical-align: middle:

  Example Here / Full Screen Example

  In some cases, you will need to ensure that the html/body element's height is set to 100%.

  For vertical alignment, set the parent element's width/height to 100% and add display: table. Then for the child element, change the display to table-cell and add vertical-align: middle.

  For horizontal centering, you could either add text-align: center to center the text and any other inline children elements. Alternatively, you could use margin: 0 auto, assuming the element is block level.

html, body {_x000D_
    height: 100%;_x000D_
}_x000D_
.parent {_x000D_
    width: 100%;_x000D_
    height: 100%;_x000D_
    display: table;_x000D_
    text-align: center;_x000D_
}_x000D_
.parent > .child {_x000D_
    display: table-cell;_x000D_
    vertical-align: middle;_x000D_
}

<section class="parent">_x000D_
    <div class="child">I'm vertically/horizontally centered!</div>_x000D_
</section>

• Approach 4 - Absolutely positioned 50% from the top with displacement:

  Example Here / Full Screen Example

  This approach assumes that the text has a known height - in this instance, 18px. Just absolutely position the element 50% from the top, relative to the parent element. Use a negative margin-top value that is half of the element's known height, in this case - -9px.

html, body, .container {_x000D_
    height: 100%;_x000D_
}_x000D_
_x000D_
.container {_x000D_
    position: relative;_x000D_
    text-align: center;_x000D_
}_x000D_
_x000D_
.container > p {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    left: 0;_x000D_
    right: 0;_x000D_
    margin-top: -9px;_x000D_
}

<div class="container">_x000D_
    <p>I'm vertically/horizontally centered!</p>_x000D_
</div>

• Approach 5 - The line-height method (Least flexible - not suggested):

  Example Here

  In some cases, the parent element will have a fixed height. For vertical centering, all you have to do is set a line-height value on the child element equal to the fixed height of the parent element.

  Though this solution will work in some cases, it's worth noting that it won't work when there are multiple lines of text - like this.

.parent {_x000D_
    height: 200px;_x000D_
    width: 400px;_x000D_
    background: lightgray;_x000D_
    text-align: center;_x000D_
}_x000D_
_x000D_
.parent > .child {_x000D_
    line-height: 200px;_x000D_
}

<div class="parent">_x000D_
    <span class="child">I'm vertically/horizontally centered!</span>_x000D_
</div>

I had the same problem. My solution was to make all vectors numeric.

The real answer is ... No.

So far as I have found there is no reasonable or publicly available Windows MonogoDB client which is really very sad since MongoDB is pretty sweet.

I've thought about throwing together a simple app with WPF on Codeplex ... but I haven't been super motivated.

What would features would you be interested in having? Maybe you can inspire me or others?

For example, do you just want to view DBs / collections & perhaps simple edits (so you don't have to use the shell) or do you require something more complex?

I would suggest that you use Apache's commons logging utility. It is highly scalable and supports separate log files for different loggers. See here.

Try this:

var jIsHasKids = $('#chkIsHasKids').attr('checked');
jIsHasKids = jIsHasKids.toString().toLowerCase();
//OR
jIsHasKids = jIsHasKids.val().toLowerCase();

For guys still coming around this thread:

• install node from official site (check npm and node version to check whether installed properly, yes in a new terminal/cmd);
• install nvm now and when prompt to whether manage current node with nvm click yes;
• open new cmd and run nvm on.

When you do not want to have the emails in the list that are in the database you'll can do the following:

select    u.name
        , u.EMAIL
        , a.emailadres
        , case when a.emailadres is null then 'Not exists'
               else 'Exists'
          end as 'Existence'
from      users u
          left join (          select 'email1' as emailadres
                     union all select 'email2'
                     union all select 'email3') a
            on  a.emailadres = u.EMAIL)

this way you'll get a result like

name | email  | emailadres | existence
-----|--------|------------|----------
NULL | NULL   | [email protected]    | Not exists
Jan  | [email protected] | [email protected]     | Exists

Using the IN or EXISTS operators are more heavy then the left join in this case.

Good luck :)

Try this code. This seems working in my case.

$this->db->where(array('id !='=> $id))

you can use visual studio for java http://visualstudiogallery.msdn.microsoft.com/bc561769-36ff-4a40-9504-e266e8706f93

Yes, the "is" keyword:

if (c is TForm)

Checks if an object is compatible with a given type. For example, it can be determined if an object is compatible with the string type like this:

You can create a custom link as described here using a small jQuery script

$('.linkPinIt').click(function(){
    var url = $(this).attr('href');
    var media = $(this).attr('data-image');
    var desc = $(this).attr('data-desc');
    window.open("//www.pinterest.com/pin/create/button/"+
    "?url="+url+
    "&media="+media+
    "&description="+desc,"_blank","top=0,right=0,width=750,height=320");
    return false; 
});

this will work for all links with class linkPinItwhich have the image and the description stored in the HTML 5 data attributes data-image and data-desc

<a href="https%3A%2F%2Fwww.flickr.com%2Fphotos%2Fkentbrew%2F6851755809%2F"

Installing the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 worked for me with a similar problem, and helped with another (slightly different) driver issue.

I created an extension for RelativeLayout that shows/hides Layouts with animations. It can extend any kind of View to gain these features.

import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.AnimationUtils;
import android.widget.RelativeLayout;

public class AnimatingRelativeLayout extends RelativeLayout
{
    Context context;
    Animation inAnimation;
    Animation outAnimation;

    public AnimatingRelativeLayout(Context context)
    {
        super(context);
        this.context = context;
        initAnimations();

    }

    public AnimatingRelativeLayout(Context context, AttributeSet attrs)
    {
        super(context, attrs);
        this.context = context;
        initAnimations();
    }

    public AnimatingRelativeLayout(Context context, AttributeSet attrs, int defStyle)
    {
        super(context, attrs, defStyle);
        this.context = context;
        initAnimations();
    }

    private void initAnimations()
    {
        inAnimation = (AnimationSet) AnimationUtils.loadAnimation(context, R.anim.in_animation);
        outAnimation = (Animation) AnimationUtils.loadAnimation(context, R.anim.out_animation);
    }

    public void show()
    {
        if (isVisible()) return;
        show(true);
    }

    public void show(boolean withAnimation)
    {
        if (withAnimation) this.startAnimation(inAnimation);
        this.setVisibility(View.VISIBLE);
    }

    public void hide()
    {
        if (!isVisible()) return;
        hide(true);
    }

    public void hide(boolean withAnimation)
    {
        if (withAnimation) this.startAnimation(outAnimation);
        this.setVisibility(View.GONE);
    }

    public boolean isVisible()
    {
        return (this.getVisibility() == View.VISIBLE);
    }

    public void overrideDefaultInAnimation(Animation inAnimation)
    {
        this.inAnimation = inAnimation;
    }

    public void overrideDefaultOutAnimation(Animation outAnimation)
    {
        this.outAnimation = outAnimation;
    }
}

You can override the original Animations using overrideDefaultInAnimation and overrideDefaultOutAnimation

My original Animations were fadeIn/Out, I am adding XML animation files for Translating in/out of the screen (Translate to top and from top)

in_animation.xml:

    <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="600"
    android:fillAfter="false"
    android:fromXDelta="0"
    android:fromYDelta="-100%p"
    android:toXDelta="0"
    android:toYDelta="0" />

out_animation.xml:

  <?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="600"
    android:fillAfter="false"
    android:fromXDelta="0"
    android:fromYDelta="0"
    android:toXDelta="0"
    android:toYDelta="-100%p" />

$ split -l 100 input_file output_file

where -l is the number of lines in each files. This will create:

• output_fileaa
• output_fileab
• output_fileac
• output_filead
• ....

You can use .getScript() and run your code after it loads:

 $.getScript("my_lovely_script.js", function(){

    alert("Script loaded and executed.");
    // here you can use anything you defined in the loaded script

 });

You can see a better explanation here: How do I include a JavaScript file in another JavaScript file?

After adding a jar file to a project's lib folder and after adding it to the build.gradle file as compile'path example' when you sync the gradle it add an additional line as compile files('libs/example.jar'). You just need to remove the line you previously added to the build.gradle file i.e. the compile'path example' after the gradle sync. You also need to remove the line compile fileTree(dir: 'libs', include: '*.jar')

There's probably a more direct way using regular expressions. With luck, somebody else will provide it. But here's what I'd do without needing to go to the manuals.

Create a PLSQL function to receive your input string and return a varchar2.

In the PLSQL function, do an asciistr() of your input. The PLSQL is because that may return a string longer than 4000 and you have 32K available for varchar2 in PLSQL.

That function converts the non-ASCII characters to \xxxx notation. So you can use regular expressions to find and remove those. Then return the result.

Go to your Workspace folder then go to Metadata > plugins. Delete everything from this folder. Then It will work.

Based on Daniel Krizian's comment, you can also use the pretty_breaks function from the scales library, which is imported automatically:

ggplot(dat, aes(x,y)) + geom_point() +
scale_x_continuous(breaks = scales::pretty_breaks(n = 10)) +
scale_y_continuous(breaks = scales::pretty_breaks(n = 10))

All you have to do is insert the number of ticks wanted for n.

A slightly less useful solution (since you have to specify the data variable again), you can use the built-in pretty function:

ggplot(dat, aes(x,y)) + geom_point() +
scale_x_continuous(breaks = pretty(dat$x, n = 10)) +
scale_y_continuous(breaks = pretty(dat$y, n = 10))

You can easily convert the string data type to numerical data type.

Don't forget to change collectionName & FieldName. for ex : CollectionNmae : Users & FieldName : Contactno.

Try this query..

db.collectionName.find().forEach( function (x) {
x.FieldName = parseInt(x.FieldName);
db.collectionName.save(x);
});

you can try fancybox: http://fancyapps.com/fancybox/

you just need load jquery and fancybox.css and fancybox.js :

<!-- Add jquery -->
<script type="text/javascript" src="jquery.min.js"></script>

<!-- Add fancyBox -->
<link rel="stylesheet" href="jquery.fancybox.css" type="text/css" media="screen" />
<script type="text/javascript" src="jquery.fancybox.pack.js"></script>

and add js code in your page:

$("youBtnSelector").click(function() {
    $.fancybox.open({
        href : 'you html path',
        type : 'iframe',
        padding : 5
    });
})

It is easy to do

There are a few efficient ways to implement this. Let's start with required imports:

from pyspark.sql.functions import col, expr, when

You can use Hive IF function inside expr:

new_column_1 = expr(
    """IF(fruit1 IS NULL OR fruit2 IS NULL, 3, IF(fruit1 = fruit2, 1, 0))"""
)

or when + otherwise:

new_column_2 = when(
    col("fruit1").isNull() | col("fruit2").isNull(), 3
).when(col("fruit1") == col("fruit2"), 1).otherwise(0)

Finally you could use following trick:

from pyspark.sql.functions import coalesce, lit

new_column_3 = coalesce((col("fruit1") == col("fruit2")).cast("int"), lit(3))

With example data:

df = sc.parallelize([
    ("orange", "apple"), ("kiwi", None), (None, "banana"), 
    ("mango", "mango"), (None, None)
]).toDF(["fruit1", "fruit2"])

you can use this as follows:

(df
    .withColumn("new_column_1", new_column_1)
    .withColumn("new_column_2", new_column_2)
    .withColumn("new_column_3", new_column_3))

and the result is:

+------+------+------------+------------+------------+
|fruit1|fruit2|new_column_1|new_column_2|new_column_3|
+------+------+------------+------------+------------+
|orange| apple|           0|           0|           0|
|  kiwi|  null|           3|           3|           3|
|  null|banana|           3|           3|           3|
| mango| mango|           1|           1|           1|
|  null|  null|           3|           3|           3|
+------+------+------------+------------+------------+

My comment: help does not include attitude which is a bonus. The attitude post enabled me to search further and find the info.

Remove all wsdl* files in your /tmp folder on the server.

WSDL files are cached in your default location for all cache files defined in php.ini. Same location as your session files.

You can do a form.serializeArray(), then add name-value pairs before posting:

var form = $(this).closest('form');

form = form.serializeArray();

form = form.concat([
    {name: "customer_id", value: window.username},
    {name: "post_action", value: "Update Information"}
]);

$.post('/change-user-details', form, function(d) {
    if (d.error) {
        alert("There was a problem updating your user details")
    } 
});

just use a reference:

Vec3b & color = image.at<Vec3b>(y,x);
color[2] = 13;

What Arrays.toString() does is create a string representation of each individual byte in your byteArray.

Please check the API documentation Arrays API

To convert your response string back to the original byte array, you have to use split(",") or something and convert it into a collection and then convert each individual item in there to a byte to recreate your byte array.

Here is a rough jQuery implementation of tvanfosson's idea:

$(document).ready(function(){

   idleTime = 0;

   //Increment the idle time counter every second.
   var idleInterval = setInterval(timerIncrement, 1000);

   function timerIncrement()
   {
     idleTime++;
     if (idleTime > 2)
     {
       doPreload();
     }
   }

   //Zero the idle timer on mouse movement.
   $(this).mousemove(function(e){
      idleTime = 0;
   });

   function doPreload()
   {
     //Preload images, etc.
   }

})

Functions like textcolor worked in old compilers like turbo C and Dev C. In today's compilers these functions would not work. I am going to give two function SetColor and ChangeConsoleToColors. You copy paste these functions code in your program and do the following steps.The code I am giving will not work in some compilers.

The code of SetColor is -

 void SetColor(int ForgC)
 {
     WORD wColor;

      HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
      CONSOLE_SCREEN_BUFFER_INFO csbi;

                       //We use csbi for the wAttributes word.
     if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
     {
                 //Mask out all but the background attribute, and add in the forgournd     color
          wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
          SetConsoleTextAttribute(hStdOut, wColor);
     }
     return;
 }

To use this function you need to call it from your program. For example I am taking your sample program -

#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include <dos.h>
#include <dir.h>

int main(void)
{
  SetColor(4);
  printf("\n \n \t This text is written in Red Color \n ");
  getch();
  return 0;
}

void SetColor(int ForgC)
 {
 WORD wColor;

  HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
  CONSOLE_SCREEN_BUFFER_INFO csbi;

                       //We use csbi for the wAttributes word.
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                 //Mask out all but the background attribute, and add in the forgournd color
      wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
      SetConsoleTextAttribute(hStdOut, wColor);
 }
 return;
}

When you run the program you will get the text color in RED. Now I am going to give you the code of each color -

Name         | Value
             |
Black        |   0
Blue         |   1
Green        |   2
Cyan         |   3
Red          |   4
Magenta      |   5
Brown        |   6
Light Gray   |   7
Dark Gray    |   8
Light Blue   |   9
Light Green  |   10
Light Cyan   |   11
Light Red    |   12
Light Magenta|   13
Yellow       |   14
White        |   15

Now I am going to give the code of ChangeConsoleToColors. The code is -

void ClearConsoleToColors(int ForgC, int BackC)
 {
 WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
               //Get the handle to the current output buffer...
 HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
                     //This is used to reset the carat/cursor to the top left.
 COORD coord = {0, 0};
                  //A return value... indicating how many chars were written
                    //   not used but we need to capture this since it will be
                      //   written anyway (passing NULL causes an access violation).
  DWORD count;

                               //This is a structure containing all of the console info
                      // it is used here to find the size of the console.
 CONSOLE_SCREEN_BUFFER_INFO csbi;
                 //Here we will set the current color
 SetConsoleTextAttribute(hStdOut, wColor);
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                          //This fills the buffer with a given character (in this case 32=space).
      FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);

      FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
                          //This will set our cursor position for the next print statement.
      SetConsoleCursorPosition(hStdOut, coord);
 }
 return;
}

In this function you pass two numbers. If you want normal colors just put the first number as zero and the second number as the color. My example is -

#include <windows.h>          //header file for windows
#include <stdio.h>

void ClearConsoleToColors(int ForgC, int BackC);

int main()
{
ClearConsoleToColors(0,15);
Sleep(1000);
return 0;
}
void ClearConsoleToColors(int ForgC, int BackC)
{
 WORD wColor = ((BackC & 0x0F) << 4) + (ForgC & 0x0F);
               //Get the handle to the current output buffer...
 HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
                     //This is used to reset the carat/cursor to the top left.
 COORD coord = {0, 0};
                  //A return value... indicating how many chars were written
                    //   not used but we need to capture this since it will be
                      //   written anyway (passing NULL causes an access violation).
 DWORD count;

                               //This is a structure containing all of the console info
                      // it is used here to find the size of the console.
 CONSOLE_SCREEN_BUFFER_INFO csbi;
                 //Here we will set the current color
 SetConsoleTextAttribute(hStdOut, wColor);
 if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
 {
                          //This fills the buffer with a given character (in this case 32=space).
      FillConsoleOutputCharacter(hStdOut, (TCHAR) 32, csbi.dwSize.X * csbi.dwSize.Y, coord, &count);

      FillConsoleOutputAttribute(hStdOut, csbi.wAttributes, csbi.dwSize.X * csbi.dwSize.Y, coord, &count );
                          //This will set our cursor position for the next print statement.
      SetConsoleCursorPosition(hStdOut, coord);
 }
 return;
} 

In this case I have put the first number as zero and the second number as 15 so the console color will be white as the code for white is 15. This is working for me in code::blocks. Hope it works for you too.

It's also worth checking out this bug report, which was closed with reason "Not a defect" and the following text:

"Autoboxing of entire arrays is not specified behavior, for good reason. It can be prohibitively expensive for large arrays."

I used this library called Parser. It worked for what I needed.

import React, { Component } from 'react';    
import Parser from 'html-react-parser';

class MyComponent extends Component {
  render() {
    <div>{Parser(this.state.message)}</div>
  }
};

public class TrackingSystemApplication {

    public static void main(String[] args) {
        SpringApplication.run(TrackingSystemApplication.class, args);
    }

    @Bean
    public WebMvcConfigurer corsConfigurer() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addCorsMappings(CorsRegistry registry) {
                registry.addMapping("/**").allowedOrigins("http://localhost:4200").allowedMethods("PUT", "DELETE",
                        "GET", "POST");
            }
        };
    }

}

For Windows : Uncomment this line in your php.ini file

;extension=php_gd2.dll

If the above step doesn't work uncomment the following line as well:

;extension=gd2

You can use android:windowSoftInputMode="stateAlwaysHidden|adjustResize" in AndroidManifest.xml for your current activity, and use android:fitsSystemWindows="true" in styles or rootLayout.

I try a late, but from far sight answer:

If you want to know if values in a (any) hash are set, all above answers a true, depending of their point of view.

If you want to test your (GET/POST..) params, you should use something more special to what you expect to be the value of params[:one], something like

if params[:one]~=/   / and  params[:two]~=/[a-z]xy/

ignoring parameter (GET/POST) as if they where not set, if they dont fit like expected

just a if params[:one] with or without nil/true detection is one step to open your page for hacking, because, it is typically the next step to use something like select ... where params[:one] ..., if this is intended or not, active or within or after a framework.

an answer or just a hint

Download Microsoft Account Lockout Tools. Use LockoutStatus to find the last DC that didn't pre-authenticate the user that is having issues. Note date and time. Log into that DC, find that timeframe and check Client Address. Logoff from those servers.

After I installed Visual Studio 2013 Update 2, Visual Studio notified me about a Windows Phone emulator update, which I installed (it was really a new component, not an update). It turned out this enabled Hyper-V, which broke HAXM.

The solution was to uninstall the emulator from Programs and Features and to turn off Hyper-V from Windows Features (search for "Windows Features" and click "Turn Windows features on or off").

Example:

Properties pro = new Properties();
FileInputStream in = new FileInputStream("D:/prop/prop.properties");
pro.load(in);
String temp1[];
String temp2[];
// getting values from property file
String username = pro.getProperty("usernamev3");//key value in prop file 
String password = pro.getProperty("passwordv3");//eg. username="zub"
String delimiter = ",";                         //password="abc"
temp1=username.split(delimiter);
temp2=password.split(delimiter);

You can use

[5,10].min 

or

[4,7].max

It's a method for Arrays.

Solution I have json object which has data

[{"name":"Ata","email":"[email protected]"}]

You can use following approach to iterate through ng-repeat and use table format instead of list.

<div class="container" ng-controller="fetchdataCtrl">    
  <ul ng-repeat="item in numbers">
    <li>            
      {{item.name}}: {{item.email}}
    </li>
  </ul>     
</div>

Try to use 3rd party tool, such as SQL Data Examiner which compares Oracle databases and shows you differences.

Apache 2 mod_headers

You could also enable Apache 2 mod_headers. On Fedora it's already enabled by default. If you use Ubuntu/Debian, enable it like this:

# First enable headers module for Apache 2,
# and then restart the Apache2 service
a2enmod headers
apache2 -k graceful

On Ubuntu/Debian you can configure headers in the file /etc/apache2/conf-enabled/security.conf

#
# Setting this header will prevent MSIE from interpreting files as something
# else than declared by the content type in the HTTP headers.
# Requires mod_headers to be enabled.
#
#Header set X-Content-Type-Options: "nosniff"

#
# Setting this header will prevent other sites from embedding pages from this
# site as frames. This defends against clickjacking attacks.
# Requires mod_headers to be enabled.
#
Header always set X-Frame-Options: "sameorigin"
Header always set X-Content-Type-Options nosniff
Header always set X-XSS-Protection "1; mode=block"
Header always set X-Permitted-Cross-Domain-Policies "master-only"
Header always set Cache-Control "no-cache, no-store, must-revalidate"
Header always set Pragma "no-cache"
Header always set Expires "-1"
Header always set Content-Security-Policy: "default-src 'none';"
Header always set Content-Security-Policy: "script-src 'self' www.google-analytics.com adserver.example.com www.example.com;"
Header always set Content-Security-Policy: "style-src 'self' www.example.com;"

Note: This is the bottom part of the file. Only the last three entries are CSP settings.

The first parameter is the directive, the second is the sources to be white-listed. I've added Google analytics and an adserver, which you might have. Furthermore, I found that if you have aliases, e.g, www.example.com and example.com configured in Apache 2 you should add them to the white-list as well.

Inline code is considered harmful, and you should avoid it. Copy all the JavaScript code and CSS to separate files and add them to the white-list.

While you're at it you could take a look at the other header settings and install mod_security

Use:

SELECT * 
FROM [Janus999DB].[dbo].[tblCustomerPlay] 
WHERE DatePlayed <  GetDate() 
AND DatePlayed > dateadd(minute, -30, GetDate())

WebElement select = driver.findElement(By.id("gender"));
List<WebElement> options = select.findElements(By.tagName("option"));
for (WebElement option : options) {
   if("Germany".equals(option.getText()))
       option.click();   
}

This would have been an appropriate solution to resolve the following error

Received HTTP code 407 from proxy after CONNECT

So the following commands should be necessary

git config --global http.proxyAuthMethod 'basic'
git config --global https.proxy http://user:pass@proxyserver:port

Which would generate the following config

$ cat ~/.gitconfig
[http]
        proxy = http://user:pass@proxyserver:port
        proxyAuthMethod = basic

In my case

$psql
postgres=# \g
postgres=# SELECT version();
                                                       version

Those are different APIs to access a MySQL backend

• The mysql is the historical API
• The mysqli is a new version of the historical API. It should perform better and have a better set of function. Also, the API is object-oriented.
• PDO_MySQL, is the MySQL for PDO. PDO has been introduced in PHP, and the project aims to make a common API for all the databases access, so in theory you should be able to migrate between RDMS without changing any code (if you don't use specific RDBM function in your queries), also object-oriented.

So it depends on what kind of code you want to produce. If you prefer object-oriented layers or plain functions...

My advice would be

1. PDO
2. MySQLi
3. mysql

Also my feeling, the mysql API would probably being deleted in future releases of PHP.

2018 update:

For AdMob users, this causes AdMob version 12.0.0 (currently last version). It wrongly requests READ_PHONE_STATE permission, so even if your app doesn't require READ_PHONE_STATE permission in manifest, you won't be able to update your app in the Google Play Console (it will tell you to create a privacy policy page for your app, because your app requires this permission).

See this: https://developers.google.com/android/guides/releases#march_20_2018_-_version_1200

Also, they wrote they will publish an update to 12.0.1 fixing this soon.

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

Had to install the wheel package. Everything was up to date but still giving the error.

pip install wheel

then

python setup.py bdist_wheel 

Worked without issues.

for word in d:
    if d in paid[j]:
         do_something()

will try all the words in the list d and check if they can be found in the string paid[j].

This is not very efficient since paid[j] has to be scanned again for each word in d. You could also use two sets, one composed of the words in the sentence, one of your list, and then look at the intersection of the sets.

sentence = "words don't come easy"
d = ["come", "together", "easy", "does", "it"]

s1 = set(sentence.split())
s2 = set(d)

print (s1.intersection(s2))

Output:

{'come', 'easy'}

When building attributed strings, I prefer to use the mutable subclass, just to keep things cleaner.

That being said, here's how you create a tri-color attributed string:

NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@"firstsecondthird"];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0,5)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:NSMakeRange(5,6)];
[string addAttribute:NSForegroundColorAttributeName value:[UIColor blueColor] range:NSMakeRange(11,5)];

_{typed in a browser. caveat implementor}

Obviously you're not going to hard-code in the ranges like this. Perhaps instead you could do something like:

NSDictionary * wordToColorMapping = ....;  //an NSDictionary of NSString => UIColor pairs
NSMutableAttributedString * string = [[NSMutableAttributedString alloc] initWithString:@""];
for (NSString * word in wordToColorMapping) {
  UIColor * color = [wordToColorMapping objectForKey:word];
  NSDictionary * attributes = [NSDictionary dictionaryWithObject:color forKey:NSForegroundColorAttributeName];
  NSAttributedString * subString = [[NSAttributedString alloc] initWithString:word attributes:attributes];
  [string appendAttributedString:subString];
  [subString release];
}

//display string

HTTP status codes say something about the HTTP protocol. HTTP 200 means transmission is OK on the HTTP level (i.e request was technically OK and server was able to respond properly). See this wiki page for a list of all codes and their meaning.

HTTP 200 has nothing to do with success or failure of your "business code". In your example the HTTP 200 is an acceptable status to indicate that your "business code error message" was successfully transferred, provided that no technical issues prevented the business logic to run properly.

Alternatively you could let your server respond with HTTP 5xx if technical or unrecoverable problems happened on the server. Or HTTP 4xx if the incoming request had issues (e.g. wrong parameters, unexpected HTTP method...) Again, these all indicate technical errors, whereas HTTP 200 indicates NO technical errors, but makes no guarantee about business logic errors.

To summarize: YES it is valid to send error messages (for non-technical issues) in your http response together with HTTP status 200. Whether this applies to your case is up to you. If for instance the client is asking for a file that isn't there, that would be more like a 404. If there is a misconfiguration on the server that might be a 500. If client asks for a seat on a plane that is booked full, that would be 200 and your "implementation" will dictate how to recognise/handle this (e.g. JSON block with a { "booking","failed" })

I've been working on something similar and after a few tries and fails came up with this:

Example: STRING-TO-TEST-ON = 'ab,cd,ef,gh'

I wanted to extract everything after the last occurrence of "," (comma) from the string... resulting in "gh".

My query is:

SELECT SUBSTR('ab,cd,ef,gh' FROM (LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1)) AS `wantedString`

Now let me try and explain what I did ...

I had to find the position of the last "," from the string and to calculate the wantedString length, using LOCATE(",",REVERSE('ab,cd,ef,gh'))-1 by reversing the initial string I actually had to find the first occurrence of the "," in the string ... which wasn't hard to do ... and then -1 to actually find the string length without the ",".

2. calculate the position of my wantedString by subtracting the string length I've calculated at 1st step from the initial string length:

   LENGTH('ab,cd,ef,gh') - (LOCATE(",",REVERSE('ab,cd,ef,gh'))-1)+1

I have (+1) because I actually need the string position after the last "," .. and not containing the ",". Hope it makes sense.

3. all it remain to do is running a SUBSTR on my initial string FROM the calculated position.

I haven't tested the query on large strings so I do not know how slow it is. So if someone actually tests it on a large string I would very happy to know the results.

Yet Another Option:

>>> [re.split(r'(\d+)', s) for s in ('foofo21', 'bar432', 'foobar12345')]
[['foofo', '21', ''], ['bar', '432', ''], ['foobar', '12345', '']]

If you would like to have the datetime,hours,minutes etc..you can use a static variable. Append the value of this variable to the filename. You can start the counter with 0 and increment when you have created a file. This way the filename will surely be unique since you have seconds also in the file.

<script>$.ready( $("input[type=text]").attr("onclick" , "this.select()"));<script>

Following could be one of ways:

dataframe = dataframe.sample(frac=1, random_state=42).reset_index(drop=True)

where

frac=1 means all rows of a dataframe

random_state=42 means keeping same order in each execution

reset_index(drop=True) means reinitialize index for randomized dataframe

It should be,

*/15 * * * *  your_command_or_whatever

I restarted my computer (Mac Mountain Lion) and the problem fixed itself. Something having to do with the shell thinking it was disconnected from the internet I think.

Restarting your shell in some definite way may solve this problem as well. Simply opening up a new session/window however did not work.

I had the same problem, and I solved it. In my case, "architectures" setting caused the problem. In my project file, Build Settings tab, Architectures were set to armv6. I changed it to Standard(armv7), do clean and build. Then it worked!

**node_modules

This works for me

recursive approach to ignore all node_modules present in sub folders

You can also evaluate your output as a sub-process, by surrounding everything with back ticks or with putting it inside $():

`ps aux | grep -ie amarok | awk '{print "kill -9 " $2}'`

 $(ps aux | grep -ie amarok | awk '{print "kill -9 " $2}')     

Use proxychains

proxychains git pull ...

update: proxychains is discontinued, use proxychains-ng instead.

Well, this question is asked many times before, and the short typical answer is: It cannot be done by pure CSS. It's in the name: Cascading Style Sheets only supports styling in cascading direction, not up.

But in most circumstances where this effect is wished, like in the given example, there still is the possibility to use these cascading characteristics to reach the desired effect. Consider this pseudo markup:

<parent>
    <sibling></sibling>
    <child></child>
</parent>

The trick is to give the sibling the same size and position as the parent and to style the sibling instead of the parent. This will look like the parent is styled!

Now, how to style the sibling?

When the child is hovered, the parent is too, but the sibling is not. The same goes for the sibling. This concludes in three possible CSS selector paths for styling the sibling:

parent sibling { }
parent sibling:hover { }
parent:hover sibling { }

These different paths allow for some nice possibilities. For instance, unleashing this trick on the example in the question results in this fiddle:

div {position: relative}
div:hover {background: salmon}
div p:hover {background: white}
div p {padding-bottom: 26px}
div button {position: absolute; bottom: 0}

Obviously, in most cases this trick depends on the use of absolute positioning to give the sibling the same size as the parent, ánd still let the child appear within the parent.

Sometimes it is necessary to use a more qualified selector path in order to select a specific element, as shown in this fiddle which implements the trick multiple times in a tree menu. Quite nice really.

Make two static cultures, one for comma and one for point.

    var commaCulture = new CultureInfo("en")
    {
        NumberFormat =
        {
            NumberDecimalSeparator = ","
        }
    };

    var pointCulture = new CultureInfo("en")
    {
        NumberFormat =
        {
            NumberDecimalSeparator = "."
        }
    };

Then use each one respectively, depending on the input (using a function):

    public double ConvertToDouble(string input)
    {
        input = input.Trim();

        if (input == "0") {
            return 0;
        }

        if (input.Contains(",") && input.Split(',').Length == 2)
        {
            return Convert.ToDouble(input, commaCulture);
        }

        if (input.Contains(".") && input.Split('.').Length == 2)
        {
            return Convert.ToDouble(input, pointCulture);
        }

        throw new Exception("Invalid input!");
    }

Then loop through your arrays

    var strings = new List<string> {"0,12", "0.122", "1,23", "00,0", "0.00", "12.5000", "0.002", "0,001"};
    var doubles = new List<double>();

    foreach (var value in strings) {
        doubles.Add(ConvertToDouble(value));
    }

This should work even though the host environment and culture changes.

With s3cmd package installed on a Linux machine, you can do this

s3cmd rm s3://foo/bar --recursive

There's a style tag, so you could do something like this:

<style type="text/css">
  .title 
  {
    color: blue;
    text-decoration: bold;
    text-size: 1em;
  }
</style>

if you're turned off by the extra line, you can use a wrapper function like so:

def with_iter(iterable):
    with iterable as iter:
        for item in iter:
            yield item

for line in with_iter(open('...')):
    ...

in Python 3.3, the yield from statement would make this even shorter:

def with_iter(iterable):
    with iterable as iter:
        yield from iter

Change to this:

@{ Response.Redirect("~/HOME/NoResults");}

You can get all keys / values and preserve the hierarchy with this

// get keys of an object or array
function getkeys(z){
  var out=[]; 
  for(var i in z){out.push(i)};
  return out;
}

// print all inside an object
function allInternalObjs(data, name) {
  name = name || 'data';
  return getkeys(data).reduce(function(olist, k){
    var v = data[k];
    if(typeof v === 'object') { olist.push.apply(olist, allInternalObjs(v, name + '.' + k)); }
    else { olist.push(name + '.' + k + ' = ' + v); }
    return olist;
  }, []);
}

// run with this
allInternalObjs({'a':[{'b':'c'},{'d':{'e':5}}],'f':{'g':'h'}}, 'ob')

time1 is the key of the most outer dictionary, eg, feb2012. So then you're trying to index the string, but you can only do this with integers. I think what you wanted was:

As you're going through each dictionary, you must add another nest.

To use Cygwin in a commercial / proprietary / non-open-source application, you'll need to fork out tens of thousands of dollars for a "license buyout" from Red Hat; this invalidates the standard licensing terms at a considerable cost. Google "cygwin license cost" and see first few results.

For mingw, no such cost is incurred, and the licenses (PD, BSD, MIT) are extremely permissive. At most you may be expected to supply license details with your application, such as the winpthreads license required when using mingw64-tdm.

EDIT thanks to Izzy Helianthus: The commercial license is no longer available or necessary because the API library found in the winsup subdirectory of Cygwin is now being distributed under the LGPL, as opposed to the full GPL.

There are two operators for type testing: E is T tests for E an instance of type T while E is! T tests for E not an instance of type T.

Note that E is Object is always true, and null is T is always false unless T===Object.

In gitk --all:

• right click on the commit you want
• -> create new branch
• enter the name of an existing branch
• press return on the dialog that confirms replacing the old branch of that name.

Beware that re-creating instead of modifying the existing branch will lose tracking-branch information. (This is generally not a problem for simple use-cases where there's only one remote and your local branch has the same name as the corresponding branch in the remote. See comments for more details, thanks @mbdevpl for pointing out this downside.)

It would be cool if gitk had a feature where the dialog box had 3 options: overwrite, modify existing, or cancel.

Even if you're normally a command-line junkie like myself, git gui and gitk are quite nicely designed for the subset of git usage they allow. I highly recommend using them for what they're good at (i.e. selectively staging hunks into/out of the index in git gui, and also just committing. (ctrl-s to add a signed-off: line, ctrl-enter to commit.)

gitk is great for keeping track of a few branches while you sort out your changes into a nice patch series to submit upstream, or anything else where you need to keep track of what you're in the middle of with multiple branches.

I don't even have a graphical file browser open, but I love gitk/git gui.

In Project Navigator in the folder Pods I had a Pods.framework in there which was red. It was also present in Linked Frameworks and Libraries. I removed both references and the error disappeared.

TL;DR

Remove Pods.framework in:

• Folder named Pods
• Linked Frameworks and Libraries

add padding to the CSS class of anchor tag. If required, add padding-top, padding-bottom,... individually according to the clickable area you want. It worked for me.

Something is clearly corrupt in your Laravel setup and it is very hard to track without more info about your environment. Usually these 2 commands help you resolve such issues

php artisan clear-compiled
composer dump-autoload

If nothing else helps then I recommend you to install fresh Laravel 5 app and copy your application logic over, it should take around 15 min or so.

If anyone is looking for a VB.Net answer (as I was initially), here it is:

Public Function IsSatisfied() As Expression(Of Func(Of Charity, String, String, Boolean))

Return Function(charity, name, referenceNumber) (String.IsNullOrWhiteSpace(name) Or
                                                         charity.registeredName.ToLower().Contains(name.ToLower()) Or

If we get the value as int and we set it to String, the error occurs. PFB my solution,

Textview = tv_property_count;
int property_id;
tv_property_count.setText(String.valueOf(property_id));

None of these solutions seem to work if you increase the amount of text so it is larger than the width of the parent container, the element to the right still gets moved below the one to the left instead of remaining next to it. To fix this, you can apply this style to the left element:

position: absolute;
width: 50px;

And apply this style to the right element:

margin-left: 50px;

Just make sure that the margin-left for the right element is greater than or equal to the width of the left element. No floating or other attributes are necessary. I would suggest wrapping these elements in a div with the style:

display: inline-block;

Applying this style may not be necessary depending on surrounding elements

Fiddle: http://jsfiddle.net/2b0bqqse/

You can see the text to the right is taller than the element to the left outlined in black. If you remove the absolute positioning and margin and instead use float as others have suggested, the text to the right will drop down below the element to the left

Fiddle: http://jsfiddle.net/qrx78u20/

.subscribe(data => {   
            console.log(data);

Not sure this will fix the problem for everyone , But uninstalling java, java SDK and installing the latest version (Version 8) fixed the issue for me ..

The command docker build --no-cache . solved our similar problem.

Our Dockerfile was:

RUN apt-get update
RUN apt-get -y install php5-fpm

But should have been:

RUN apt-get update && apt-get -y install php5-fpm

To prevent caching the update and install separately.

There are tcpdump filters for HTTP GET & HTTP POST (or for both plus message body):

• Run man tcpdump | less -Ip examples to see some examples

• Here’s a tcpdump filter for HTTP GET (GET = 0x47, 0x45, 0x54, 0x20):

  sudo tcpdump -s 0 -A 'tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420'
  

• Here’s a tcpdump filter for HTTP POST (POST = 0x50, 0x4f, 0x53, 0x54):

  sudo tcpdump -s 0 -A 'tcp dst port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)'
  

• Monitor HTTP traffic including request and response headers and message body (source):

  tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  tcpdump -X -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'

arange generates lists (well, numpy arrays); type help(np.arange) for the details. You don't need to call it on existing lists.

>>> x = [1,2,3,4]
>>> y = [3,5,7,9] 
>>> 
>>> m,b = np.polyfit(x, y, 1)
>>> m
2.0000000000000009
>>> b
0.99999999999999833

I should add that I tend to use poly1d here rather than write out "m*x+b" and the higher-order equivalents, so my version of your code would look something like this:

import numpy as np
import matplotlib.pyplot as plt

x = [1,2,3,4]
y = [3,5,7,10] # 10, not 9, so the fit isn't perfect

coef = np.polyfit(x,y,1)
poly1d_fn = np.poly1d(coef) 
# poly1d_fn is now a function which takes in x and returns an estimate for y

plt.plot(x,y, 'yo', x, poly1d_fn(x), '--k')
plt.xlim(0, 5)
plt.ylim(0, 12)

I had the same problem and I've found the cause.

I have avast! antivirus installed in my computer, and it asked me to install the update for chrome plugin. The new avast! plugin for chrome has the functionality to block ads and tracking, and, by default, it blocks the facebook access. I have solved my problem simply allowing facebook in the avast! chrome plugin for the website I needed.

Since this question is very old, I think that some people might have the same cause as me, the new avast! chrome plugin.

    $search = array('/&lsquo;/u', '/&rsquo;/u', '/&ldquo;/u', '/&rdquo;/u', '/&mdash;/u');
    $replace = array('\'', '\'', '"', '"', '-');
    $text = preg_replace($search, $replace, $text);
    //make sure _all_ html entities are converted to the plain ascii equivalents - it appears
    //in some MS headers, some html entities are encoded and some aren't
    //$text = html_entity_decode($text, ENT_QUOTES, 'UTF-8');
    //try to strip out any C style comments first, since these, embedded in html comments, seem to
    //prevent strip_tags from removing html comments (MS Word introduced combination)
    if(mb_stripos($text, '/*') !== FALSE){
        $text = mb_eregi_replace('#/\*.*?\*/#s', '', $text, 'm');
    }
    //introduce a space into any arithmetic expressions that could be caught by strip_tags so that they won't be
    //'<1' becomes '< 1'(note: somewhat application specific)
    $text = preg_replace(array('/<([0-9]+)/'), array('< $1'), $text);
    $text = strip_tags($text, $allowed_tags);
    //eliminate extraneous whitespace from start and end of line, or anywhere there are two or more spaces, convert it to one
    $text = preg_replace(array('/^\s\s+/', '/\s\s+$/', '/\s\s+/u'), array('', '', ' '), $text);
    //strip out inline css and simplify style tags

    $num_matches = preg_match_all("/\<!--/u", $text, $matches);
    if($num_matches){
        $text = preg_replace('/\<!--(.)*--\>/isu', '', $text);

As of the date of this answer (March 2020) there is a plugin for chrome called CORS unblock that allows you to skip that browser policy. The 'same origin policy' is an important security feature of browsers. Please only install this plugin for development or testing purposes. Do not promote its installation in end client browsers because you compromise the security of users and the chrome community will be forced to remove this plugin from the store.

Edit: Use printf("val = 0x%" PRIx64 "\n", val); instead.

Try printf("val = 0x%llx\n", val);. See the printf manpage:

ll (ell-ell). A following integer conversion corresponds to a long long int or unsigned long long int argument, or a following n conversion corresponds to a pointer to a long long int argument.

Edit: Even better is what @M_Oehm wrote: There is a specific macro for that, because unit64_t is not always a unsigned long long: PRIx64 see also this stackoverflow answer

Update Oct 2020:

So if you are on this page scratching your head why my favicon is not working , then read along. I tried all the things (which I supposedly thought I was doing right) yet favicon was not showing up on browser tabs.

Here is one line simple cracker code that worked flawlessly:

<link rel="icon" href="https://abcde.neocities.org/bla123.jpg" size="16x16" type="image/jpg">

Notes:

1. Put the image in the ROOT folder ( In one of my unsuccessful attempts , I was not using root dir)
2. Use direct favicon url link ( instead of href="images/bla123.jpg").
3. I placed this tag just below the <title> tag in the <Header>
4. I made the favicon size 64x64 px and size was 2.16 KB

I tested it on Firefox, Chrome, Edge, and opera. OS: Win 10, Mac OSX, ios and Android .Also I did not experience any cashing issues, worked pretty much as soon as I refreshed the page.

You can also simply use the HtmlString class

    @(new HtmlString(Model.Content))

The question has been answered, but for your future coding reference you might like to consider this.

In your HTML, add the name as an attribute to the button and remove the onclick reference.

<button id="button" data-name="Mathew" type="button">click</button>

In your JavaScript, grab the button using its ID, assign the function to the button's click event, and use the function to display the button's data-name attribute.

var button = document.getElementById('button');

button.onclick = myfunction;

function myfunction() {
  var name = this.getAttribute('data-name');
  alert(name);
}

you're better off reading a line and then doing a split.

File file = new File("path/to/file");
String words[]; // I miss C
String line;
HashMap<String, String> hm = new HashMap<>();
try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), "UTF-8")))
{
    while((line = br.readLine() != null)){
        words = line.split("\\s");
        if (hm.containsKey(words[0])){
                System.out.println("Found duplicate ... handle logic");
        }
        hm.put(words[0],words[1]); //if index==0 is ur key
    }

} catch (FileNotFoundException e) {
        e.printStackTrace();
} catch (IOException e) {
        e.printStackTrace();
}

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}

I had hit the same problem and learnt the following-

Even though database has a default character set of utf-8, it's possible for database columns to have a different character set in MySQL. Modified dB and the problematic column to UTF-8:

mysql> ALTER DATABASE MyDB CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci'

mysql> ALTER TABLE database.table MODIFY COLUMN column_name VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL;

Now creating new tables with:

> CREATE TABLE My_Table_Name (
    twitter_id_str VARCHAR(255) NOT NULL UNIQUE,
    twitter_screen_name VARCHAR(512) CHARACTER SET utf8 COLLATE utf8_unicode_ci,
    .....
  ) CHARACTER SET utf8 COLLATE utf8_unicode_ci;

You can combine multiple conditions to avoid the situation:

CASE WHEN condition1 = true AND condition2 = true THEN calculation1 
     WHEN condition1 = true AND condition2 = false 
     ELSE 'what so ever' END,

I had the same problem so i decided to start writing a small tool to help me with this. Im gonna share andopen source it.

It supports, JAVA, C# & Objective-c from JSON .

As you are using SQL Server 2008, go with Martin's answer.

If you find yourself needing to do it in SQL Server 2005 where you don't have access to the Date column type, I'd use:

SELECT DATEADD(DAY, DATEDIFF(DAY, 0, GETDATE()), 0)

SQLFiddle

You have a couple of questions here, so I'll address them separately:

I need to store a number of selected items in one field in a database

My general rule is: don't. This is something which all but requires a second table (or third) with a foreign key. Sure, it may seem easier now, but what if the use case comes along where you need to actually query for those items individually? It also means that you have more options for lazy instantiation and you have a more consistent experience across multiple frameworks/languages. Further, you are less likely to have connection timeout issues (30,000 characters is a lot).

You mentioned that you were thinking about using ENUM. Are these values fixed? Do you know them ahead of time? If so this would be my structure:

Base table (what you have now):

| id primary_key sequence
| -- other columns here.

Items table:

| id primary_key sequence
| descript VARCHAR(30) UNIQUE

Map table:

| base_id  bigint
| items_id bigint

Map table would have foreign keys so base_id maps to Base table, and items_id would map to the items table.

And if you'd like an easy way to retrieve this from a DB, then create a view which does the joins. You can even create insert and update rules so that you're practically only dealing with one table.

What format should I use store the data?

If you have to do something like this, why not just use a character delineated string? It will take less processing power than a CSV, XML, or JSON, and it will be shorter.

What column type should I use store the data?

Personally, I would use TEXT. It does not sound like you'd gain much by making this a BLOB, and TEXT, in my experience, is easier to read if you're using some form of IDE.

Suppose the data is in the B column, write in the C column the formula:

=SUBSTITUTE(B1," ","")

Copy&Paste the formula in the whole C column.

edit: using commas or semicolons as parameters separator depends on your regional settings (I have to use the semicolons). This is weird I think. Thanks to @tocallaghan and @pablete for pointing this out.

Actually, on Android Studio it is possible. You can have nested resources as shown here :

There is also a plugin to group resources here.

I recommend to avoid this though.

KOTLIN

There is also the possibility to use sufficientlysecure.htmltextview.HtmlTextView

Use like below in gradle files:

Project gradle file:

repositories {
    jcenter()
}

App gradle file:

dependencies {
implementation 'org.sufficientlysecure:html-textview:3.9'
}

Inside xml file replace your textView with:

<org.sufficientlysecure.htmltextview.HtmlTextView
      android:id="@+id/allNewsBlockTextView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_margin="2dp"
      android:textColor="#000"
      android:textSize="18sp"
      app:htmlToString="@{detailsViewModel.selectedText}" />

Last line above is if you use Binding adapters where the code will be like:

@BindingAdapter("htmlToString")
fun bindTextViewHtml(textView: HtmlTextView, htmlValue: String) {

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    textView.setHtml(
        htmlValue,
        HtmlHttpImageGetter(textView, "n", true)
    );
    } else {
        textView.setHtml(
        htmlValue,
        HtmlHttpImageGetter(textView, "n", true)
        );
    }
}

More info from github page and a big thank you to the authors!!!!!

You have a few different options:

• you can use a SPA router like SammyJS, or Angularjs and ui-router, so your pages are stateful.
• use sessionStorage to store your state.
• store the values on the URL hash.

yeah, its so simple to fix that, just open that file by notepad++ and step follow --> Encoding\ encoding UTF-8 without BOM. then save that. It work for me as well!

Postgresql > 8.4

SELECT 
    row_number() OVER (ORDER BY col1) AS i, 
    e.col1, 
    e.col2, 
    ... 
FROM ... 

SELECT LAST(row_name) FROM table_name

You can use these string functions,

strstr — Find the first occurrence of a string

stristr — Case-insensitive strstr()

strrchr — Find the last occurrence of a character in a string

strpos — Find the position of the first occurrence of a substring in a string

strpbrk — Search a string for any of a set of characters

If that doesn't help then you should use preg regular expression

preg_match — Perform a regular expression match

For people who have no experience in building websites (like me) I tried a lot, only to find out that I hadn't used the .php extension, but the .html extension.

O(n), because you traverse each node once. Or rather - the amount of work you do for each node is constant (does not depend on the rest of the nodes).

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..

Assuming that you want to insert/update single row, most optimal approach is to use SQL Server's REPEATABLE READ transaction isolation level:

SET TRANSACTION ISOLATION LEVEL REPEATABLE READ;
BEGIN TRANSACTION

    IF (EXISTS (SELECT * FROM myTable WHERE key=@key)
        UPDATE myTable SET ...
        WHERE key=@key
    ELSE
        INSERT INTO myTable (key, ...)
        VALUES (@key, ...)

COMMIT TRANSACTION

This isolation level will prevent/block subsequent repeatable read transactions from accessing same row (WHERE key=@key) while currently running transaction is open. On the other hand, operations on another row won't be blocked (WHERE key=@key2).

Issue Log: App Not Setup. This app is still in development mode. and you dont have access to it. register test user or ask an app admin for permission

1. The app are not in Live Mode
2. You are not listed as admin or a tester in
   https://developers.facebook.com/app/yourapp
3. Your App Hashkey are not set. if Facebook app cant be on Live Mode you need a hashkey to test it. because the app are not yet Live. Facebook wont allow an access.

HOW TO CHANGE TO LIVE MODE
1. go to : https://developers.facebook.com
2. select your app on "My Apps" List
3. toggle the switch from OFF to ON

HOW TO ADD AS TEST OR ADMIN
1. go to : https://developers.facebook.com
2. select your app on "My Apps" List
3. go to : Roles > Roles > Press Add for example administrator 4. Search your new admin/tester Facebook account.
5. admin must enter facebook password to confirm.then submit
the new admin must go to developer.facebook page and accept the request
6. go to : https://developers.facebook.com

7. Profile > Requests > Confirm
8. Congratulation you have been assign as new Admin

HOW TO GET AND SET HASHKEY FOR DEVELOPMENT
as Refer to Facebook Login Documentation
https://developers.facebook.com/docs/android/getting-started/#create_hash
The most preferable solution by me is by code ( Troubleshooting Sample Apps )
it will print out the hash key. you can update it on
https://developers.facebook.com/apps/yourFacebookappID/settings/basic/
on Android > Key Hashes section

a step by step process on how to get the hashKey.

1. Firstly Add the code to any oncreate method

2. Run The app and Search the KeyHash at Logcat

step by step process on how Update on Facebook Developer.

3. Open Facebook Developer Page. You need access as to update the Facebook Developer page.

4. Follow the step as follow.

I realize this is an older post, but thought this might be helpful to anyone wondering the same question:

While the previous answers are no doubt valid, there is a more simple reason for the distinction between textarea and input.

As mentioned previously, HTML is used to describe and give as much semantic structure to web content as possible, including input forms. A textarea may be used for input, however a textarea can also be marked as read only via the readonly attribute. The existence of such an attribute would not make any sense for an input type, and thus the distinction.

There is one more option to rename field:

Jackson MixIns.

Useful if you deal with third party classes, which you are not able to annotate, or you just do not want to pollute the class with Jackson specific annotations.

The Jackson documentation for Mixins is outdated, so this example can provide more clarity. In essence: you create mixin class which does the serialization in the way you want. Then register it to the ObjectMapper:

objectMapper.addMixIn(ThirdParty.class, MyMixIn.class);

<ScrollViewer Height="239" VerticalScrollBarVisibility="Auto">
    <TextBox AcceptsReturn="True" TextWrapping="Wrap" LineHeight="10" />
</ScrollViewer>

This is way to use the scrolling TextBox in XAML and use it as a text area.

It depends upon the .NET Framework that you use. Check Jon Skeet's answer about Versions.

Here is short version of his answer.

C# 1.0 released with .NET 1.0

C# 1.2 (bizarrely enough); released with .NET 1.1

C# 2.0 released with .NET 2.0

C# 3.0 released with .NET 3.5

C# 4.0 released with .NET 4

C# 5.0 released with .NET 4.5

C# 6.0 released with .NET 4.6

C# 7.0 is released with .NET 4.6.2

C# 7.3 is released with .NET 4.7.2

C# 8.0 is released with NET Core 3.0

C# 9.0 is released with NET 5.0

You're using jQuery version 3.1.0 and the load event is deprecated for use since jQuery version 1.8. The load event is removed from jQuery 3.0. Instead you can use on method and bind the JavaScript load event:

 $(window).on('load', function () {
      alert("Window Loaded");
 });

Use VSC or any other editor that has Live server, it will give you a proxy that will allow you to use GET or FETCH

Visual Studio 2003 doesn't seem to allow you to set environment variables for debugging.

What I do in C/C++ is use _putenv() in main() and set any variables. Usually I surround it with a #if defined DEBUG_MODE / #endif to make sure only certain builds have it.

_putenv("MYANSWER=42");

I believe you can do the same thing with C# using os.putenv(), i.e.

os.putenv('MYANSWER', '42');

These will set the envrironment variable for that shell process only, and as such is an ephemeral setting, which is what you are looking for.

By the way, its good to use process explorer (http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx), which is a sysinternals tool. You can see what a given process' copy of the environment variables is, so you can validate that what you set is what you got.

IIRC, it involves garbage collection strategies. The theory is that a client and server will be different in terms of short-lived objects, which is important for modern GC algorithms.

Here is a link on server mode. Alas, they don't mention client mode.

Here is a very thorough link on GC in general; this is a more basic article. Not sure if either address -server vs -client but this is relevant material.

At No Fluff Just Stuff, both Ken Sipe and Glenn Vandenburg do great talks on this kind of thing.

Command to install GCC and Development Tools on a CentOS / RHEL 7 server

Type the following yum command as root user:

You need to turn off the compiler optimisation.

If you are interested in a particular variable in gdb, you can delare the variable as "volatile" and recompile the code. This will make the compiler turn off compiler optimization for that variable.

volatile int quantity = 0;

If you have the capability to do so, I would recommend using either mod-jk or mod-proxy-ajp to pass requests from Apache to JBoss. The AJP protocol is much more efficient compared to using HTTP proxy requests and as a benefit, JBoss will see the request as coming from the original client and not Apache.

I dont know what do you exactly mean but hope it help you.
by this directive you can access the DOM element inside controller
this is sample that help you to focus element inside controller

.directive('scopeElement', function () {
    return {
        restrict:"A", // E-Element A-Attribute C-Class M-Comments
        replace: false,
        link: function($scope, elem, attrs) {
            $scope[attrs.scopeElement] = elem[0];
        }
    };
})

now, inside HTML

<input scope-element="txtMessage" >

then, inside controller :

.controller('messageController', ['$scope', function ($scope) {
    $scope.txtMessage.focus();
}])

You can see the difference with the following example:

<a href="http://www.google.co.uk/" onclick="return (confirm('Follow this link?'))">Google</a>

Clicking "Okay" returns true, and the link is followed. Clicking "Cancel" returns false and doesn't follow the link. If javascript is disabled the link is followed normally.

Can't think of a only css solution, but couldn't you just had a div between those 2 and set in the css the properties to look like a line like shown in the image? If you are using divs as they were table cells this is a pretty simple solution to the problem

I think this covers just about all of the browsers. I have used it successfully in the past.

#div {
    filter: alpha(opacity=50); /* internet explorer */
    -khtml-opacity: 0.5;      /* khtml, old safari */
    -moz-opacity: 0.5;       /* mozilla, netscape */
    opacity: 0.5;           /* fx, safari, opera */
}

To those would prefer to keep it simple, stupid; If you rather get rid of the notices instead of installing a helper or downgrading, simply disable the error in your settings.json by adding this:

"intelephense.diagnostics.undefinedTypes": false

Here are some dplyr options:

# sample data
df <- data.frame(a = c('1', NA, '3', NA), b = c('a', 'b', 'c', NA), c = c('e', 'f', 'g', NA))

library(dplyr)

# remove rows where all values are NA:
df %>% filter_all(any_vars(!is.na(.)))
df %>% filter_all(any_vars(complete.cases(.)))  


# remove rows where only some values are NA:
df %>% filter_all(all_vars(!is.na(.)))
df %>% filter_all(all_vars(complete.cases(.)))  

# or more succinctly:
df %>% filter(complete.cases(.))  
df %>% na.omit

# dplyr and tidyr:
library(tidyr)
df %>% drop_na

I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.

Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.

Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.

This will clean the caches used to store bundle dependency resolution and eclipse extension registry data. Using this option will force eclipse to reinitialize these caches.

1. Open command prompt (cmd)
2. Go to eclipse application location (D:\eclipse)
3. Run command eclipse -clean

    <artifactId>maven-deploy-plugin</artifactId>

This version is what broke my builds:

    public static void Copy(String SourceFile, String TargetFile)
    {

        FileStream fis = null;
        FileStream fos = null;

            try
            {
                Console.Write("## Try No. " + a + " : (Write from " + SourceFile + " to " + TargetFile + ")\n");

                fis = new FileStream(SourceFile, FileMode.Open, FileAccess.ReadWrite);
                fos = new FileStream(TargetFile, FileMode.Create, FileAccess.ReadWrite);

                int intbuffer = 5242880;
                byte[] b = new byte[intbuffer];

                int i;
                while ((i = fis.Read(b, 0, intbuffer)) > 0)
                {
                    fos.Write(b, 0, i);
                }

                Console.Write("Writing file : " + TargetFile + " is successful.\n");

                break;
            }
            catch (Exception e)
            {
                Console.Write("Writing file : " + TargetFile + " is unsuccessful.\n");
                Console.Write(e);
            }
            finally
            {
                if (fis != null)
                {
                    fis.Close();
                }
                if (fos != null)
                {
                    fos.Close();
                }
            }
    }

The code above will read a big file and write to a new big file. The "intbuffer" value can be set in multiple of 1024. While both source and target file are open, it reads the big file by bytes and write to the new target file by bytes. It will not go out of memory.

One more thing that could cause this is having incorrect version of the <parent> project.

In my case it was pointing to a non-existing project and for some reason IntelliJ downgraded version in settings to 1.5 and later when I fixed it, it was still interpreting target code version as 5 (despite setting it to 11).

Math.round also returns an integer value, so you don't need to typecast.

int b = Math.round(float a);

I use the below query

If you have not pushed the code to your remote branch (GitHub/Bitbucket) you can change the commit message on the command line as below.

 git commit --amend -m "Your new message"

If you're working on a specific branch, do this:

git commit --amend -m "BRANCH-NAME: new message"

If you've already pushed the code with a wrong message then you need to be careful when changing the message. i.e after you change the commit message and try pushing it again you end up with having issues. To make it smooth follow the following steps.

Please read the entire answer before doing it

git commit --amend -m "BRANCH-NAME : your new message"

git push -f origin BRANCH-NAME                # Not a best practice. Read below why?

Important note: When you use the force push directly you might end up with code issues that other developers are working on the same branch. So to avoid those conflicts you need to pull the code from your branch before making the force push:

 git commit --amend -m "BRANCH-NAME : your new message"
 git pull origin BRANCH-NAME
 git push -f origin BRANCH-NAME

This is the best practice when changing the commit message, if it was already pushed.

    boolean x;
    for (x = false, 
        map.put("One", new Integer(1)), 
        map.put("Two", new Integer(2)),      
        map.put("Three", new Integer(3)); x;);

Ignoring the declaration of x (which is necessary to avoid an "unreachable statement" diagnostic), technically it's only one statement.

Take a look at the sqlcmd utility. It allows you to execute SQL from the command line.

http://msdn.microsoft.com/en-us/library/ms162773.aspx

It's all in there in the documentation, but the syntax should look something like this:

sqlcmd -U myLogin -P myPassword -S MyServerName -d MyDatabaseName 
    -Q "DROP TABLE MyTable"

There is an Oracle article I found regarding Java 9 module system

By default, a type in a module is not accessible to other modules unless it’s a public type and you export its package. You expose only the packages you want to expose. With Java 9, this also applies to reflection.

As pointed out in https://stackoverflow.com/a/50251958/134894, the differences between the AccessibleObject#setAccessible for JDK8 and JDK9 are instructive. Specifically, JDK9 added

This method may be used by a caller in class C to enable access to a member of declaring class D if any of the following hold:

• C and D are in the same module.
• The member is public and D is public in a package that the module containing D exports to at least the module containing C.
• The member is protected static, D is public in a package that the module containing D exports to at least the module containing C, and C is a subclass of D.
• D is in a package that the module containing D opens to at least the module containing C. All packages in unnamed and open modules are open to all modules and so this method always succeeds when D is in an unnamed or open module.

which highlights the significance of modules and their exports (in Java 9)

I would expect that the JVM gracefully interrupts (thread.interrupt()) all the running threads created by the application, at least for signals SIGINT (kill -2) and SIGTERM (kill -15).

This way, the signal will be forwarded to them, allowing a gracefully thread cancellation and resource finalization in the standard ways.

But this is not the case (at least in my JVM implementation: Java(TM) SE Runtime Environment (build 1.8.0_25-b17), Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode).

As other users commented, the usage of shutdown hooks seems mandatory.

So, how do I would handle it?

Well first, I do not care about it in all programs, only in those where I want to keep track of user cancellations and unexpected ends. For example, imagine that your java program is a process managed by other. You may want to differentiate whether it has been terminated gracefully (SIGTERM from the manager process) or a shutdown has occurred (in order to relaunch automatically the job on startup).

As a basis, I always make my long-running threads periodically aware of interrupted status and throw an InterruptedException if they interrupted. This enables execution finalization in way controlled by the developer (also producing the same outcome as standard blocking operations). Then, at the top level of the thread stack, InterruptedException is captured and appropriate clean-up performed. These threads are coded to known how to respond to an interruption request. High cohesion design.

So, in these cases, I add a shutdown hook, that does what I think the JVM should do by default: interrupt all the non-daemon threads created by my application that are still running:

Runtime.getRuntime().addShutdownHook(new Thread() {
    @Override
    public void run() {
        System.out.println("Interrupting threads");
        Set<Thread> runningThreads = Thread.getAllStackTraces().keySet();
        for (Thread th : runningThreads) {
            if (th != Thread.currentThread() 
                && !th.isDaemon() 
                && th.getClass().getName().startsWith("org.brutusin")) {
                System.out.println("Interrupting '" + th.getClass() + "' termination");
                th.interrupt();
            }
        }
        for (Thread th : runningThreads) {
            try {
                if (th != Thread.currentThread() 
                && !th.isDaemon() 
                && th.isInterrupted()) {
                    System.out.println("Waiting '" + th.getName() + "' termination");

The SSL certificates are going to be bound to hostname rather than IP if they are setup in the standard way. Hence why it works at one site rather than the other.

Even if the servers share the same hostname they may well have two different certificates and hence WebSphere will have a certificate trust issue as it won't be able to recognise the certificate on the second server as it is different to the first.

Thanks @A.B for good solution

Despite this being against the general SO policy on these matters, this seems to be what the OP genuinely wants:

http://www.google.com/search?btnG=1&pws=0&q=java+executable+wrapper

If you'd like, you could also try creating the appropriate batch or script file containing the single line:

java -jar MyJar.jar

Or in many cases on windows just double clicking the executable jar.

If you just want the bug fix to be integrated into the branch, git cherry-pick the relevant commit(s).

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

Detect OS Version:

    public static string OS_Name()
    {
        return (string)(from x in new ManagementObjectSearcher(
            "SELECT Caption FROM Win32_OperatingSystem").Get().Cast<ManagementObject>() 
            select x.GetPropertyValue("Caption")).FirstOrDefault();
    }

In Chrome, you are supposed to be able to allow this capability with a runtime flag --allow-file-access-from-files

However, it looks like there is a problem with current versions of Chrome (37, 38) where this doesn't work unless you also pass the runtime flag --disable-web-security

That's an unacceptable solution, except perhaps as a short-term workaround, but it has been identified as an issue: https://code.google.com/p/chromium/issues/detail?id=379206

Note: I see that someone (not @unutbu) changed the referenced answer so that it no longer uses vars()['Foo'] — so the primary point of my post no longer applies.

FWIW, here's what I meant about @unutbu's answer only working with locally defined classes — and that using eval() instead of vars() would make it work with any accessible class, not only those defined in the current scope.

For those who dislike using eval(), a way is also shown to avoid it.

First here's a concrete example demonstrating the potential problem with using vars():

class Foo(object): pass
class Bar(Foo): pass
class Baz(Foo): pass
class Bing(Bar): pass

# unutbu's approach
def all_subclasses(cls):
    return cls.__subclasses__() + [g for s in cls.__subclasses__()
                                       for g in all_subclasses(s)]

print(all_subclasses(vars()['Foo']))  # Fine because  Foo is in scope
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

def func():  # won't work because Foo class is not locally defined
    print(all_subclasses(vars()['Foo']))

try:
    func()  # not OK because Foo is not local to func()
except Exception as e:
    print('calling func() raised exception: {!r}'.format(e))
    # -> calling func() raised exception: KeyError('Foo',)

print(all_subclasses(eval('Foo')))  # OK
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

# using eval('xxx') instead of vars()['xxx']
def func2():
    print(all_subclasses(eval('Foo')))

func2()  # Works
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

This could be improved by moving the eval('ClassName') down into the function defined, which makes using it easier without loss of the additional generality gained by using eval() which unlike vars() is not context-sensitive:

# easier to use version
def all_subclasses2(classname):
    direct_subclasses = eval(classname).__subclasses__()
    return direct_subclasses + [g for s in direct_subclasses
                                    for g in all_subclasses2(s.__name__)]

# pass 'xxx' instead of eval('xxx')
def func_ez():
    print(all_subclasses2('Foo'))  # simpler

func_ez()
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

Lastly, it's possible, and perhaps even important in some cases, to avoid using eval() for security reasons, so here's a version without it:

def get_all_subclasses(cls):
    """ Generator of all a class's subclasses. """
    try:
        for subclass in cls.__subclasses__():
            yield subclass
            for subclass in get_all_subclasses(subclass):
                yield subclass
    except TypeError:
        return

def all_subclasses3(classname):
    for cls in get_all_subclasses(object):  # object is base of all new-style classes.
        if cls.__name__.split('.')[-1] == classname:
            break
    else:
        raise ValueError('class %s not found' % classname)
    direct_subclasses = cls.__subclasses__()
    return direct_subclasses + [g for s in direct_subclasses
                                    for g in all_subclasses3(s.__name__)]

# no eval('xxx')
def func3():
    print(all_subclasses3('Foo'))

func3()  # Also works
# -> [<class '__main__.Bar'>, <class '__main__.Baz'>, <class '__main__.Bing'>]

I install the Oracle server and it allows to connect from the local machine with no problem. But from another Maclaptop on my home network, it can't connect using either Sql Developer or Sql Plus. After doing some research, I figured out there is this additional step you have to do:

Use the Oracle net manager. Select the Listener. Add the IP address (in my case it is 192.168.1.12) besides of the 127.0.0.1 or localhost.

This will end up add an entry to the [OracleHome]\product\11.2.0\dbhome_1\network\admin\listener.ora

• restart the listener service. (note: for me I reboot machine once to make it work)

• Use lsnrctl status to verify
  Notice the additional HOST=192.168.1.12 shows up and this is what to make remote connection to work.

What was helpful for me (MacBook):

• first go to File -> Invalidate Caches / Restart -> Invalidate and Restart
• then check the value of JAVA_HOME enviroment variable, by calling echo $JAVA_HOME (it should be equal to "/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home")
• if it is not, change its value by calling export JAVA_HOME="/Applications/Android Studio.app/Contents/jre/jdk/Contents/Home"

Try this, working fine -

$array = json_decode(json_encode($array), true);

Check host file which like this

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost

You can set the DataContext for your control, form, etc. like so:

DataContext="{Binding RelativeSource={RelativeSource Self}}"

Clarification:

The data context being set to the value above should be done at whatever element "owns" the code behind -- so for a Window, you should set it in the Window declaration.

I have your example working with this code:

<Window x:Class="MyClass"
  Title="{Binding windowname}"
  DataContext="{Binding RelativeSource={RelativeSource Self}}"
  Height="470" Width="626">

The DataContext set at this level then is inherited by any element in the window (unless you explicitly change it for a child element), so after setting the DataContext for the Window you should be able to just do straight binding to CodeBehind properties from any control on the window.

I just clean the arraylist , try values.clear();

values = new ArrayList<String>();
values.clear();

ArrayAdapter <String> adapter;
adapter = new ArrayAdapter<String>(this, R.layout.list,android.R.id.text1, values); 
lista.setAdapter(adapter);

You are encoding to UTF-8, then re-encoding to UTF-8. Python can only do this if it first decodes again to Unicode, but it has to use the default ASCII codec:

>>> u'ñ'
u'\xf1'
>>> u'ñ'.encode('utf8')
'\xc3\xb1'
>>> u'ñ'.encode('utf8').encode('utf8')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 0: ordinal not in range(128)

Don't keep encoding; leave encoding to UTF-8 to the last possible moment instead. Concatenate Unicode values instead.

You can use str.join() (or, rather, unicode.join()) here to concatenate the three values with dashes in between:

nombre = u'-'.join(fabrica, sector, unidad)
return nombre.encode('utf-8')

but even encoding here might be too early.

Rule of thumb: decode the moment you receive the value (if not Unicode values supplied by an API already), encode only when you have to (if the destination API does not handle Unicode values directly).

There are an infinite number of rational numbers, and a finite number of bits with which to represent them. See http://en.wikipedia.org/wiki/Floating_point#Accuracy_problems.

Parameter names are only useful to the compiler. When the compiler generates a class file, the parameter names are not included - a method's argument list only consists of the number and types of its arguments. So it would be impossible to retrieve the parameter name using reflection (as tagged in your question) - it doesn't exist anywhere.

However, if the use of reflection is not a hard requirement, you can retrieve this information directly from the source code (assuming you have it).

I have seen comments in INI files, so yes. Please refer to this Wikipedia article. I could not find an official specification, but that is the correct syntax for comments, as many game INI files had this as I remember.

Edit

The API returns the Value and the Comment (forgot to mention this in my reply), just construct and example INI file and call the API on this (with comments) and you can see how this is returned.

I find that TRUNCATE TABLE .. has trouble with foreign key constraints, even after a NOCHECK CONSTRAINT ALL, so I use a DELETE FROM statement instead. This does mean that identity seeds are not reset, you could always add a DBCC CHECKIDENT to achieve this.

I Use the code below to print out to the message window the sql for truncating all the tables in the database, before running it. It just makes it a bit harder to make a mistake.

EXEC sp_MSforeachtable 'PRINT ''ALTER TABLE ? NOCHECK CONSTRAINT ALL'''
EXEC sp_MSforeachtable 'print ''DELETE FROM ?'''
EXEC sp_MSforeachtable 'print ''ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all'''

You can get data types from the information_schema (8.4 docs referenced here, but this is not a new feature):

=# select column_name, data_type from information_schema.columns
-# where table_name = 'config';
    column_name     | data_type 
--------------------+-----------
 id                 | integer
 default_printer_id | integer
 master_host_enable | boolean
(3 rows)

Android Studio -> Preferences -> Editor -> Intentions -> Java -> Declaration -> Enable "Add JavaDoc"

And, While selecting Methods to Implement (Ctrl/Cmd + i), on the left bottom, you should be seeing checkbox to enable Copy JavaDoc.

the user pressing enter or spaces is the same.

int count = 5;
int list[count]; // array of known length
cout << "enter the sequence of " << count << " numbers space separated: ";
// user inputs values space separated in one line.  Inputs more than the count are discarded.
for (int i=0; i<count; i++) {
    cin >> list[i];
}

For such you must rely on VBA. You can't do it just with Excel functions.

I just want to echo sam9046's modest comment as an alternative and potentially much easier solution that worked in my case: uninstall and install homebrew again from scratch. No sudo commands required.

You can also browse/modify the uninstall script from that link above if you need to ensure it won't affect your previously installed packages. In my case this was just my home machine so I just started over.

To add a little to @Bakuriu's answer:

If you already know where the warning is likely to occur then it's often cleaner to use the numpy.errstate context manager, rather than numpy.seterr which treats all subsequent warnings of the same type the same regardless of where they occur within your code:

import numpy as np

a = np.r_[1.]
with np.errstate(divide='raise'):
    try:
        a / 0   # this gets caught and handled as an exception
    except FloatingPointError:
        print('oh no!')
a / 0           # this prints a RuntimeWarning as usual

Edit:

In my original example I had a = np.r_[0], but apparently there was a change in numpy's behaviour such that division-by-zero is handled differently in cases where the numerator is all-zeros. For example, in numpy 1.16.4:

all_zeros = np.array([0., 0.])
not_all_zeros = np.array([1., 0.])

with np.errstate(divide='raise'):
    not_all_zeros / 0.  # Raises FloatingPointError

with np.errstate(divide='raise'):
    all_zeros / 0.  # No exception raised

with np.errstate(invalid='raise'):
    all_zeros / 0.  # Raises FloatingPointError

The corresponding warning messages are also different: 1. / 0. is logged as RuntimeWarning: divide by zero encountered in true_divide, whereas 0. / 0. is logged as RuntimeWarning: invalid value encountered in true_divide. I'm not sure why exactly this change was made, but I suspect it has to do with the fact that the result of 0. / 0. is not representable as a number (numpy returns a NaN in this case) whereas 1. / 0. and -1. / 0. return +Inf and -Inf respectively, per the IEE 754 standard.

If you want to catch both types of error you can always pass np.errstate(divide='raise', invalid='raise'), or all='raise' if you want to raise an exception on any kind of floating point error.

You can only accomplish this with PHP comments.

 <!-- <tr>
      <td><?php //echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php //echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php //echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php //echo $sort_order; ?>" size="1" /></td>
    </tr> -->

The way that PHP and HTML works, it is not able to comment in one swoop unless you do:

<?php

/*

echo <<<ENDHTML
 <tr>
          <td>{$entry_keyword}</td>
          <td><input type="text" name="keyword" value="{echo $keyword}" /></td>
        </tr>
        <tr>
          <td>{$entry_sort_order}</td>
          <td><input name="sort_order" value="{$sort_order}" size="1" /></td>
        </tr>
ENDHTML;

*/
?>

You can use "transparent" as a colour. In some versions of IE, that comes up as black, but I've not tested it out since the IE6 days.

Based on Tabare's Answer, I had to add one more day at the end, since the cycle is cut before

var start = new Date("02/05/2013");
var end = new Date("02/10/2013");
var newend = end.setDate(end.getDate()+1);
var end = new Date(newend);
while(start < end){
   alert(start);           

   var newDate = start.setDate(start.getDate() + 1);
   start = new Date(newDate);
}
