I realize this is a somewhat older question, but I just wanted to point out that you've add the model variable to your test widget class incorrectly. If you need a Model variable, you shouldn't be trying to pass it in through the component constructor. You are only intended to pass services or other types of injectables that way. If you are instantiating your test widget inside of another component and need to pass a model object as, I would recommend using the angular core OnInit and Input/Output design patterns.

As an example, your code should really look something like this:

import { Component, Input, OnInit } from "@angular/core";
import { YourModelLoadingService } from "../yourModuleRootFolderPath/index"

class Model {
    param1: string;
}

@Component({
    selector: "testWidget",
    template: "<div>This is a test and {{model.param1}} is my param.</div>",
    providers: [ YourModelLoadingService ]
})

export class testWidget implements OnInit {
    @Input() model: Model; //Use this if you want the parent component instantiating this
        //one to be able to directly set the model's value
    private _model: Model; //Use this if you only want the model to be private within
        //the component along with a service to load the model's value
    constructor(
        private _yourModelLoadingService: YourModelLoadingService //This service should
        //usually be provided at the module level, not the component level
    ) {}

    ngOnInit() {
        this.load();
    }

    private load() {
        //add some code to make your component read only,
        //possibly add a busy spinner on top of your view
        //This is to avoid bugs as well as communicate to the user what's
        //actually going on

        //If using the Input model so the parent scope can set the contents of model,
        //add code an event call back for when model gets set via the parent
        //On event: now that loading is done, disable read only mode and your spinner
        //if you added one

        //If using the service to set the contents of model, add code that calls your
        //service's functions that return the value of model
        //After setting the value of model, disable read only mode and your spinner
        //if you added one. Depending on if you leverage Observables, or other methods
        //this may also be done in a callback
    }
}

A class which is essentially just a struct/model should not be injected, because it means you can only have a single shared instanced of that class within the scope it was provided. In this case, that means a single instance of Model is created by the dependency injector every time testWidget is instantiated. If it were provided at the module level, you would only have a single instance shared among all components and services within that module.

Instead, you should be following standard Object Oriented practices and creating a private model variable as part of the class, and if you need to pass information into that model when you instantiate the instance, that should be handled by a service (injectable) provided by the parent module. This is how both dependency injection and communication is intended to be performed in angular.

Also, as some of the other mentioned, you should be declaring your model classes in a separate file and importing the class.

I would strongly recommend going back to the angular documentation reference and reviewing the basics pages on the various annotations and class types: https://angular.io/guide/architecture

You should pay particular attention to the sections on Modules, Components and Services/Dependency Injection as these are essential to understanding how to use Angular on an architectural level. Angular is a very architecture heavy language because it is so high level. Separation of concerns, dependency injection factories and javascript versioning for browser comparability are mainly handled for you, but you have to use their application architecture correctly or you'll find things don't work as you expect.

You should know more about java.lang.Math.max:

1. java.lang.Math.max(arg1,arg2) only accepts 2 arguments but you are writing 3 arguments in your code.
2. The 2 arguments should be double,int,long and float but your are writing String arguments in Math.max function. You need to parse them in the required type.

You code will produce compile time error because of above mismatches.

Try following updated code, that will solve your purpose:

import java.lang.Math;
import java.util.Scanner;
public class max {
    public static void main(String[] args) {
        Scanner keyboard = new Scanner(System.in);
        System.out.println("Please input 3 integers: ");
        int x = Integer.parseInt(keyboard.nextLine());
        int y = Integer.parseInt(keyboard.nextLine());
        int z = Integer.parseInt(keyboard.nextLine());
        int max = Math.max(x,y);
        if(max>y){ //suppose x is max then compare x with z to find max number
            max = Math.max(x,z);    
        }
        else{ //if y is max then compare y with z to find max number
            max = Math.max(y,z);    
        }
        System.out.println("The max of three is: " + max);
    }
} 

pip list -v can be used to list packages' install locations, introduced in https://pip.pypa.io/en/stable/news/#b1-2018-03-31

This feature is introduced in pip 10.0.0b1. On Ubuntu 18.04 (Bionic Beaver), pip or pip3 installed with sudo apt install python-pip or sudo apt install python3-pip is 9.0.1 which doesn't have this feature.

Check https://github.com/pypa/pip/issues/5599 for suitable ways of upgrading pip or pip3.

On vb.net you must write @ModelType.

Of course @Stephan202 has given a really nice answer. I am providing an alternative.

def compressx(min_index = 3, max_index = 6, x = ['a', 'b', 'c', 'd', 'e', 'f', 'g']):
    x = x[:min_index] + [''.join(x[min_index:max_index])] + x[max_index:]
    return x
compressx()

>>>['a', 'b', 'c', 'def', 'g']

You can also do the following.

x = x[:min_index] + [''.join(x[min_index:max_index])] + x[max_index:]
print(x)

>>>['a', 'b', 'c', 'def', 'g']

Python opens files almost in the same way as in C:

• r+ Open for reading and writing. The stream is positioned at the beginning of the file.

• a+ Open for reading and appending (writing at end of file). The file is created if it does not exist. The initial file position for reading is at the beginning of the file, but output is appended to the end of the file (but in some Unix systems regardless of the current seek position).

There is of course a lubridate solution for this:

library(lubridate)
date <- "2009-10-01"

ymd(date) - 5
# [1] "2009-09-26"

is the same as

ymd(date) - days(5)
# [1] "2009-09-26"

Other time formats could be:

ymd(date) - months(5)
# [1] "2009-05-01"

ymd(date) - years(5)
# [1] "2004-10-01"

ymd(date) - years(1) - months(2) - days(3)
# [1] "2008-07-29"

You can aliasing both query and Selecting them in the select query
http://sqlfiddle.com/#!2/ca27b/1

SELECT x.a, y.b FROM (SELECT * from a) as x, (SELECT * FROM b) as y

1. .py: This is normally the input source code that you've written.
2. .pyc: This is the compiled bytecode. If you import a module, python will build a *.pyc file that contains the bytecode to make importing it again later easier (and faster).
3. .pyo: This was a file format used before Python 3.5 for *.pyc files that were created with optimizations (-O) flag. (see the note below)
4. .pyd: This is basically a windows dll file. http://docs.python.org/faq/windows.html#is-a-pyd-file-the-same-as-a-dll

Also for some further discussion on .pyc vs .pyo, take a look at: http://www.network-theory.co.uk/docs/pytut/CompiledPythonfiles.html (I've copied the important part below)

• When the Python interpreter is invoked with the -O flag, optimized code is generated and stored in ‘.pyo’ files. The optimizer currently doesn't help much; it only removes assert statements. When -O is used, all bytecode is optimized; .pyc files are ignored and .py files are compiled to optimized bytecode.
• Passing two -O flags to the Python interpreter (-OO) will cause the bytecode compiler to perform optimizations that could in some rare cases result in malfunctioning programs. Currently only __doc__ strings are removed from the bytecode, resulting in more compact ‘.pyo’ files. Since some programs may rely on having these available, you should only use this option if you know what you're doing.
• A program doesn't run any faster when it is read from a ‘.pyc’ or ‘.pyo’ file than when it is read from a ‘.py’ file; the only thing that's faster about ‘.pyc’ or ‘.pyo’ files is the speed with which they are loaded.
• When a script is run by giving its name on the command line, the bytecode for the script is never written to a ‘.pyc’ or ‘.pyo’ file. Thus, the startup time of a script may be reduced by moving most of its code to a module and having a small bootstrap script that imports that module. It is also possible to name a ‘.pyc’ or ‘.pyo’ file directly on the command line.

Note:

On 2015-09-15 the Python 3.5 release implemented PEP-488 and eliminated .pyo files. This means that .pyc files represent both unoptimized and optimized bytecode.

First of all, you should use the JOIN syntax rather than FROM table1, table2, and you should always limit the grouping to as little fields as you need.

Altought I haven't tested, your first query seems fine to me, but could be re-written as:

SELECT s.sid, s.name
FROM 
    Supplier s
    INNER JOIN (
       SELECT su.sid
       FROM Supplies su
       GROUP BY su.sid
       HAVING COUNT(DISTINCT su.jid) > 1
    ) g
        ON g.sid = s.sid

Or simplified as:

SELECT sid, name
FROM Supplier s
WHERE (
    SELECT COUNT(DISTINCT su.jid)
    FROM Supplies su
    WHERE su.sid = s.sid
) > 1

However, your second query seems wrong to me, because you should also GROUP BY pid.

 SELECT s.sid, s.name
    FROM 
        Supplier s
        INNER JOIN (
            SELECT su.sid
            FROM Supplies su
            GROUP BY su.sid, su.pid
            HAVING COUNT(DISTINCT su.jid) > 1
        ) g
            ON g.sid = s.sid

As you may have noticed in the query above, I used the INNER JOIN syntax to perform the filtering, however it can be also written as:

SELECT s.sid, s.name
FROM Supplier s
WHERE (
     SELECT COUNT(DISTINCT su.jid)
     FROM Supplies su
     WHERE su.sid = s.sid
     GROUP BY su.sid, su.pid
) > 1

Unfortunately, for me, setting "Expires" did not always work. The cookie was unaffected.

This code did work for me:

HttpContext.Current.Session.Abandon();
HttpContext.Current.Response.Cookies.Add(new HttpCookie("ASP.NET_SessionId", ""));

where "ASP.NET_SessionId" is the name of the cookie. This does not really delete the cookie, but overrides it with a blank cookie, which was close enough for me.

From your comment:

this line DateTime Date = reader.GetDateTime(0); was throwing the exception

The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:

SELECT * from INFO

Replace it with a query that retrieves only the two columns you're interested in:

SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO

Then try reading the values again:

var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1);  // equivalent to time(7) from your database

Or:

var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];

If @Region is not a null value (lets say @Region = 'South') it will not return rows where the Region field is null, regardless of the value of ANSI_NULLS.

ANSI_NULLS will only make a difference when the value of @Region is null, i.e. when your first query essentially becomes the second one.

In that case, ANSI_NULLS ON will not return any rows (because null = null will yield an unknown boolean value (a.k.a. null)) and ANSI_NULLS OFF will return any rows where the Region field is null (because null = null will yield true)

If both arrays are in the correct order; where each item corresponds to its associated member identifier then you can simply use.

var merge = _.merge(arr1, arr2);

Which is the short version of:

var merge = _.chain(arr1).zip(arr2).map(function(item) {
    return _.merge.apply(null, item);
}).value();

Or, if the data in the arrays is not in any particular order, you can look up the associated item by the member value.

var merge = _.map(arr1, function(item) {
    return _.merge(item, _.find(arr2, { 'member' : item.member }));
});

You can easily convert this to a mixin. See the example below:

_.mixin({_x000D_
  'mergeByKey' : function(arr1, arr2, key) {_x000D_
    var criteria = {};_x000D_
    criteria[key] = null;_x000D_
    return _.map(arr1, function(item) {_x000D_
      criteria[key] = item[key];_x000D_
      return _.merge(item, _.find(arr2, criteria));_x000D_
    });_x000D_
  }_x000D_
});_x000D_

My humble test program. I use it to play around with the formatter and look-up long dates that I find in log-files (but who has put them there...).

My test program:

package be.test.package.time;

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class TimeWork {

    public static void main(String[] args) {    

        TimeZone timezone = TimeZone.getTimeZone("UTC");

        List<Long> longs = new ArrayList<>();
        List<String> strings = new ArrayList<>();

        //Formatting a date needs a timezone - otherwise the date get formatted to your system time zone.
        //Use 24h format HH. In 12h format hh can be in range 0-11, which makes 12 overflow to 0.
        DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss.SSS");
        formatter.setTimeZone(timezone);

        Date now = new Date();

myArrayOfMatrices = zeros(unknown,500,800);

If you're running out of memory throw more RAM in your system, and make sure you're running a 64 bit OS. Also try reducing your precision (do you really need doubles or can you get by with singles?):

myArrayOfMatrices = zeros(unknown,500,800,'single');

To append to that array try:

myArrayOfMatrices(unknown+1,:,:) = zeros(500,800);

As mentioned in a comment above, you can have expressions within the template strings/literals. Example:

const one = 1;_x000D_
const two = 2;_x000D_
const result = `One add two is ${one + two}`;_x000D_
console.log(result); // output: One add two is 3

It appears that by default php does not log errors anywhere, the error_log key in php.ini is commented out in all the install's I've seen.

Generally I:

1. look for php.ini files. locate php.ini.

2. Search these files for the error_reporting value;

   Which should be set to whatever amalgamation of php log levels are enough for you.,

   Eg: E_ALL & ~E_DEPRECATED & ~E_STRICT

3. Check the error_log value to make sure it points to an actual place and is not commented out.

   The default value doesn't give a full path, only a file name, I don't know where this path resolves to normally. Probably /var/log/.

Andy E is correct that there is no HTML-based way to do this*; but if you are willing to use Flash, you can do it. The following works reliably on systems that have Flash installed. If your app needs to work on iPhone, then of course you'll need a fallback HTML-based solution.

* (Update 4/22/2013: HTML does now support this, in HTML5. See the other answers.)

Flash uploading also has other advantages -- Flash gives you the ability to show a progress bar as the upload of a large file progresses. (I'm pretty sure that's how Gmail does it, by using Flash behind the scenes, although I may be wrong about that.)

Here is a sample Flex 4 app that allows the user to pick a file, and then displays it:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
               xmlns:s="library://ns.adobe.com/flex/spark"

               creationComplete="init()">
    <fx:Declarations>
        <!-- Place non-visual elements (e.g., services, value objects) here -->
    </fx:Declarations>
    <s:Button x="10" y="10" label="Choose file..." click="showFilePicker()" />
    <mx:Image id="myImage" x="9" y="44"/>
    <fx:Script>
        <![CDATA[
            private var fr:FileReference = new FileReference();

            // Called when the app starts.
            private function init():void
            {
                // Set up event handlers.
                fr.addEventListener(Event.SELECT, onSelect);
                fr.addEventListener(Event.COMPLETE, onComplete);
            }

            // Called when the user clicks "Choose file..."
            private function showFilePicker():void
            {
                fr.browse();
            }

            // Called when fr.browse() dispatches Event.SELECT to indicate
            // that the user has picked a file.
            private function onSelect(e:Event):void
            {
                fr.load(); // start reading the file
            }

            // Called when fr.load() dispatches Event.COMPLETE to indicate
            // that the file has finished loading.
            private function onComplete(e:Event):void
            {
                myImage.data = fr.data; // load the file's data into the Image
            }
        ]]>
    </fx:Script>
</s:Application>

In this simple way

char str [10] = "IAmCute";
printf ("%c",str[4]);

In Addition to the suggestions, I would also suggest annotating your Repository interface with @Repository.

The Spring IOC may not detect this as a repository and thus be unable to detect the entity and its corresponding property.

Exported variables such as $HOME and $PATH are available to (inherited by) other programs run by the shell that exports them (and the programs run by those other programs, and so on) as environment variables. Regular (non-exported) variables are not available to other programs.

$ env | grep '^variable='
$                                 # No environment variable called variable
$ variable=Hello                  # Create local (non-exported) variable with value
$ env | grep '^variable='
$                                 # Still no environment variable called variable
$ export variable                 # Mark variable for export to child processes
$ env | grep '^variable='
variable=Hello
$
$ export other_variable=Goodbye   # create and initialize exported variable
$ env | grep '^other_variable='
other_variable=Goodbye
$

For more information, see the entry for the export builtin in the GNU Bash manual, and also the sections on command execution environment and environment.

Note that non-exported variables will be available to subshells run via ( ... ) and similar notations because those subshells are direct clones of the main shell:

$ othervar=present
$ (echo $othervar; echo $variable; variable=elephant; echo $variable)
present
Hello
elephant
$ echo $variable
Hello
$

The subshell can change its own copy of any variable, exported or not, and may affect the values seen by the processes it runs, but the subshell's changes cannot affect the variable in the parent shell, of course.

Some information about subshells can be found under command grouping and command execution environment in the Bash manual.

Assuming the first byte is the least significant byte:

long value = 0;
for (int i = 0; i < by.length; i++)
{
   value += ((long) by[i] & 0xffL) << (8 * i);
}

Is the first byte the most significant, then it is a little bit different:

long value = 0;
for (int i = 0; i < by.length; i++)
{
   value = (value << 8) + (by[i] & 0xff);
}

Replace long with BigInteger, if you have more than 8 bytes.

Thanks to Aaron Digulla for the correction of my errors.

You could use Canvas

in HTML, simply add a canva

<canvas id="locations" width="400" height="300" style="border:1px solid #d3d3d3;">
Your browser can't read canvas</canvas>

And in Javascript (only an example, that will draw a rectangle on the picture)

var c = document.getElementById("locations");
var ctx = c.getContext("2d");
var img = new Image(); 
img.src = '{main_photo}';
img.onload = function() {    // after the pic is loaded
    ctx.drawImage(this,0,0); // add the picture
    ctx.beginPath();         // start the rectangle
    ctx.moveTo(50,50);
    ctx.lineTo(200,50);
    ctx.lineTo(200,200);
    ctx.lineTo(50,200);
    ctx.lineTo(50,50);

    ctx.strokeStyle = "sienna"; // set color
    ctx.stroke();               // apply color
    ctx.lineWidth = 5;
    // ctx.closePath();
};

In the toolbar in the bottom right corner you will see a item that looks like the following: After clicking on it you will get the option to indent using either spaces or tabs. After selecting your indent type you will then have the option to change how big an indent is. In the case of the example above, indentation is set to 4 space characters per indent. If tab is selected as your indentation character then you will see Tab Size instead of Spaces

If you want to have this apply to all files and not on an idividual file basis, override the Editor: Tab Size and Editor: Insert Spaces settings in either User Settings or Workspace Settings depending on your needs

Edit 1

To get to your user or workspace settings go to Preferences -> Settings. Verify that you are on the User or Workspace tab depending on your needs and use the search bar to locate the settings. You may also want to disable Editor: Detect Indentation as this setting will override what you set for Editor: Insert Spaces and Editor: Tab Size when it is enabled

If you are using Netbeans to manage Tomcat, try to disable HTTP monitor in Tools - Servers

Short answer

Just copy an image into your res/drawable folder and use

imageView.setImageResource(R.drawable.my_image);

Details

The variety of answers can cause a little confusion. We have

• setBackgroundResource()
• setBackgroundDrawable()
• setBackground()
• setImageResource()
• setImageDrawable()
• setImageBitmap()

The methods with Background in their name all belong to the View class, not to ImageView specifically. But since ImageView inherits from View you can use them, too. The methods with Image in their name belong specifically to ImageView.

The View methods all do the same thing as each other (though setBackgroundDrawable() is deprecated), so we will just focus on setBackgroundResource(). Similarly, the ImageView methods all do the same thing, so we will just focus on setImageResource(). The only difference between the methods is they type of parameter you pass in.

Setup

Here is a FrameLayout that contains an ImageView. The ImageView initially doesn't have any image in it. (I only added the FrameLayout so that I could put a border around it. That way you can see the edge of the ImageView.)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <FrameLayout
        android:id="@+id/frameLayout"
        android:layout_width="250dp"
        android:layout_height="250dp"
        android:background="@drawable/border"
        android:layout_centerInParent="true">

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    </FrameLayout>
</RelativeLayout>

Below we will compare the different methods.

setImageResource()

If you use ImageView's setImageResource(), then the image keeps its aspect ratio and is resized to fit. Here are two different image examples.

• imageView.setImageResource(R.drawable.sky);
• imageView.setImageResource(R.drawable.balloons);

setBackgroundResource()

Using View's setBackgroundResource(), on the other hand, causes the image resource to be stretched to fill the view.

• imageView.setBackgroundResource(R.drawable.sky);
• imageView.setBackgroundResource(R.drawable.balloons);

Both

The View's background image and the ImageView's image are drawn separately, so you can set them both.

imageView.setBackgroundResource(R.drawable.sky);
imageView.setImageResource(R.drawable.balloons);

For python3 there's a very simple and convenient python module ping3: (pip install ping3, needs root privileges).

from ping3 import ping, verbose_ping
ping('example.com')  # Returns delay in seconds.
>>> 0.215697261510079666

This module allows for the customization of some parameters as well.

PK - Primary Key

NN - Not Null

BIN - Binary (stores data as binary strings. There is no character set so sorting and comparison is based on the numeric values of the bytes in the values.)

UN - Unsigned (non-negative numbers only. so if the range is -500 to 500, instead its 0 - 1000, the range is the same but it starts at 0)

UQ - Create/remove Unique Key

ZF - Zero-Filled (if the length is 5 like INT(5) then every field is filled with 0’s to the 5th digit. 12 = 00012, 400 = 00400, etc. )

AI - Auto Increment

G - Generated column. i.e. value generated by a formula based on the other columns

There is another place where the TNS location is stored: If you're using Windows, open regedit and navigate to My HKEY Local Machine/Software/ORACLE/KEY_OraClient10_home1 where KEY_OraClient10_home1 is your Oracle home. If there is a string entry called TNS_ADMIN, then the value of that entry will point to the TNS file that Oracle is using on your computer.

Typescript 3.5

As of Typescript 3.5, the Omit helper will be included: TypeScript 3.5 RC - The Omit Helper Type

You can use it directly, and you should remove your own definition of the Omit helper when updating.

I use this

<staticContent>
<clientCache cacheControlCustom="public" cacheControlMode="UseMaxAge" cacheControlMaxAge="500.00:00:00" />
</staticContent>

to cache static content for 500 days with public cache-control header.

Original definitive documentation

0, 1 and 2 only track how many of the necessary methods to make a request you've called so far.

3 tells you that the server's response has started to come in. But when you're using the XMLHttpRequest object from a web page there's almost nothing(*) you can do with that information, since you don't have access to the extended properties that allow you to read the partial data.

readyState 4 is the only one that holds any meaning.

(*: about the only conceivable use I can think of for checking for readyState 3 is that it signals some form of life at the server end, so you could possibly increase the amount of time you wait for a full response when you receive it.)

new ES6:

'import' should be used with 'export' key words to share variables/arrays/objects between js files:

export default myObject;

//....in another file

import myObject from './otherFile.js';

old skool:

'require' should be used with 'module.exports'

 module.exports = myObject;

//....in another file

var myObject = require('./otherFile.js');

It looks like Git tried to remove the .git/rebase-merge directory but wasn't able to remove it completely. Have you tried copying that folder away? Also copy away the .git/rebase-apply folder if that is present.

You are using a wrong overload of the Html.ActionLink helper. What you think is routeValues is actually htmlAttributes! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.

Here's what you are using:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // routeValues
    new {                                                     // htmlAttributes
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    }
)

and here's what you should use:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // controllerName
    new {                                                     // routeValues
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    },
    null                                                      // htmlAttributes
)

Also there's another very serious issue with your code. The following routeValue:

replyblogPostmodel = Model

You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel parameter from your controller action. You should use the blogPostId parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:

public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
    BlogPostModel model = repository.Get(blogPostId);
    ...
}

As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:

@Html.ActionLink(
    linkText: "Reply",
    actionName: "BlogReplyCommentAdd",
    controllerName: "Blog",
    routeValues: new {
        blogPostId = blogPostId, 
        captchaValid = Model.AddNewComment.DisplayCaptcha
    },
    htmlAttributes: null
)

Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.

I had a quite similar problem in a "test-utils" project (adding features, rules and assertions to JUnit) child of a parent project injecting dependencies. The class depending on the org.junit.rules package was in src/main/java.

So I added a dependency on junit without test scope and it solved the problem :

pom.xml of the test-util project :

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
</dependency>

pom.xml of the parent project :

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <scope>test</scope>
</dependency>

How do we retrieve a value from a text field?

mytestField.getText();

ActionListner example:

mytextField.addActionListener(this);

public void actionPerformed(ActionEvent evt) {
    String text = textField.getText();
    textArea.append(text + newline);
    textField.selectAll();
}

In your first Activity:

intent.putExtra("myTag", yourObject);

And in your second one:

myCustomObject myObject = (myCustomObject) getIntent().getSerializableExtra("myTag");

Don't forget to make your custom object Serializable:

public class myCustomObject implements Serializable {
...
}

The constraint could be removed with syntax:

ALTER TABLE

As of MySQL 8.0.19, ALTER TABLE permits more general (and SQL standard) syntax for dropping and altering existing constraints of any type, where the constraint type is determined from the constraint name: ALTER TABLE tbl_name DROP CONSTRAINT symbol;

Example:

CREATE TABLE tab(id INT, CONSTRAINT unq_tab_id UNIQUE(id));

-- checking constraint name if autogenerated
SELECT * FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS WHERE TABLE_NAME = 'tab';

-- dropping constraint
ALTER TABLE tab DROP CONSTRAINT unq_tab_id;

There are excellent answers, but if you want to color your console logs you can use the pattern :

<PatternLayout pattern="%style{%date{DEFAULT}}{yellow}
            [%t] %highlight{%-5level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green} %logger{36} - %message\n"/>

The full log4j2 file is:

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Properties>
        <Property name="APP_LOG_ROOT">/opt/test/log</Property>
    </Properties>
    <Appenders>
        <Console name="ConsoleAppender" target="SYSTEM_OUT">
            <PatternLayout pattern="%style{%date{DEFAULT}}{yellow}
                [%t] %highlight{%-5level}{FATAL=bg_red, ERROR=red, WARN=yellow, INFO=green} %logger{36} - %message\n"/>
        </Console>
        <RollingFile name="XML_ROLLING_FILE_APPENDER"
                     fileName="${APP_LOG_ROOT}/appName.log"
                     filePattern="${APP_LOG_ROOT}/appName-%d{yyyy-MM-dd}-%i.log.gz">
            <PatternLayout pattern="%d{DEFAULT} [%t] %-5level %logger{36} - %msg%n"/>
            <Policies>
                <SizeBasedTriggeringPolicy size="19500KB"/>
            </Policies>
        </RollingFile>
    </Appenders>
    <Loggers>
        <Root level="error">
            <AppenderRef ref="ConsoleAppender"/>
        </Root>
        <Logger name="com.compName.projectName" level="debug">
            <AppenderRef ref="XML_ROLLING_FILE_APPENDER"/>
        </Logger>
    </Loggers>
</Configuration>

And the logs will look like this:

td style is not necessary but will make it easier to see this example in browser

<table>
 <tr>
  <td style="border: 1px solid black; width: 200px;">
  <div style="width: 50%; float: left; text-align: left;">left</div>
  <div style="width: 50%; float: left; text-align: right;">right</div>
  </td>
 </tr>
</table>

If you use the absence of "Mobile" then its almost correct. But there are HTC Sensation 4G (4.3 inch with android 2.X) which does not send Mobile keyword.

The reason why you may want to treat it separately is due to iframes etc.

Well, since your on a shared server, you can't do anything about it. They usually set the max execution time so that you can't override it. I suggest you contact them.

Make sure that each Application Pool in IIS, under Advanced Settings has Enable 32 bit Applications set to True

You are missing a comma in your statement.

Try this:

data[data[, "Var1"]>10, ]

Or:

data[data$Var1>10, ]

Or:

subset(data, Var1>10)

As an example, try it on the built-in dataset, mtcars

data(mtcars)

mtcars[mtcars[, "mpg"]>25, ]

Use number formatter to format the value, as required. Please check this.

In MVC 3 I had to add:

using System.ComponentModel.DataAnnotations;

among usings when adding properties:

[DataType(DataType.Date)]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]

Especially if you are adding these properties in .edmx file like me. I found that by default .edmx files don't have this using so adding only propeties is not enough.

You can use simply pd.to_datetime(then) and pandas will convert the date elements into ISO date format- [YYYY-MM-DD].

You can pass this as map/apply to use it in a dataframe/series too.

The following command will do what you asked for "extract the lines between 1234 and 5555" in someFile.

sed -n '1234,5555p' someFile

"Better" is subjective.

querySelector is the newer feature.

getElementById is better supported than querySelector.

querySelector is better supported than getElementsByClassName.

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

You need to pick the appropriate tool for any given task.

(In the above, for querySelector read querySelector / querySelectorAll).

select * from sys.tables
order by schema_id      --comments: order by 'schema_id' to get the 'tables' in 'object explorer order'
go

Running on your workstation

As a general rule, processes running without root privileges cannot bind to ports below 1024.

So try a higher port, or run with elevated privileges via sudo. You can downgrade privileges after you have bound to the low port using process.setgid and process.setuid.

Running on heroku

When running your apps on heroku you have to use the port as specified in the PORT environment variable.

See http://devcenter.heroku.com/articles/node-js

const server = require('http').createServer();
const port = process.env.PORT || 3000;

server.listen(port, () => console.log(`Listening on ${port}`));

The trick is to use $ sign before single quotes. It also works for cut and other tools.

grep $'\t' sample.txt

For Linux Mint, this problem is actually referenced in the Docker website:

Note: The lsb_release -cs sub-command below returns the name of your Ubuntu distribution, such as xenial. Sometimes, in a distribution like Linux Mint, you might have to change $(lsb_release -cs) to your parent Ubuntu distribution. For example, if you are using Linux Mint Rafaela, you could use trusty.

amd64:

$ sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"

The lsb_release -cs command gives a repository for which Docker has no prepared package - you must change it to xenial.

The correct command for Linux Mint 18 which is based on Ubuntu 16.04 Xenial is

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   xenial \
   stable"

I found a simple solution, just open Settings of TortoiseSVN, and expand Icon Overlays, select Icon Set and change the icon set.

The default icon set of mine is XP Style, and I change it to Win10 because Win10 is the OS I am currently using.

Restart your computer and problem gets solved.

This PL*SQL will write to DBMS_OUTPUT a script that will drop each constraint that does not have delete cascade and recreate it with delete cascade.

There are already answers which give how to change Inner HTML of element.

But I would suggest, you should use some animation like Fade Out/ Fade In to change HTML which gives good effect of changed HTML rather instantly changing inner HTML.

Use animation to change Inner HTML

$('#regTitle').fadeOut(500, function() {
    $(this).html('Hello World!').fadeIn(500);
});

If you have many functions which need this, then you can call common function which changes inner Html.

function changeInnerHtml(elementPath, newText){
    $(elementPath).fadeOut(500, function() {
        $(this).html(newText).fadeIn(500);
    });
}

Have a look at File > Preferences > Keyboard Shortcuts (or Ctrl+K Ctrl+S)

Search for cursorColumnSelectDown or cursorColumnSelectUp which will give you the relevent keyboard shortcut. For me it is Shift+Alt+Down/Up Arrow

Do you see what the DatabaseUtils.queryNumEntries() does? It's awful! I use this.

public int getRowNumberByArgs(Object... args) {
    String where = compileWhere(args);
    String raw = String.format("SELECT count(*) FROM %s WHERE %s;", TABLE_NAME, where);
    Cursor c = getWriteableDatabase().rawQuery(raw, null);
    try {
        return (c.moveToFirst()) ? c.getInt(0) : 0;
    } finally {
        c.close();
    }
}

I think you are trying to over complicate things. A simple solution is to just style your checkbox by default with the unchecked styles and then add the checked state styles.

input[type="checkbox"] {
  // Unchecked Styles
}
input[type="checkbox"]:checked {
  // Checked Styles
}

I apologize for bringing up an old thread but felt like it could have used a better answer.

EDIT (3/3/2016):

W3C Specs state that :not(:checked) as their example for selecting the unchecked state. However, this is explicitly the unchecked state and will only apply those styles to the unchecked state. This is useful for adding styling that is only needed on the unchecked state and would need removed from the checked state if used on the input[type="checkbox"] selector. See example below for clarification.

input[type="checkbox"] {
  /* Base Styles aka unchecked */
  font-weight: 300; // Will be overwritten by :checked
  font-size: 16px; // Base styling
}
input[type="checkbox"]:not(:checked) {
  /* Explicit Unchecked Styles */
  border: 1px solid #FF0000; // Only apply border to unchecked state
}
input[type="checkbox"]:checked {
  /* Checked Styles */
  font-weight: 900; // Use a bold font when checked
}

Without using :not(:checked) in the example above the :checked selector would have needed to use a border: none; to achieve the same affect.

Use the input[type="checkbox"] for base styling to reduce duplication.

Use the input[type="checkbox"]:not(:checked) for explicit unchecked styles that you do not want to apply to the checked state.

Other than what Alex and Evan have already stated, I would like to add that a C++ struct is not like a C struct.

In C++, a struct can have methods, inheritance, etc. just like a C++ class.

For center or positioning the background image you should use background-position property . The background-position property sets the starting position of a background image from top and left sides of the element . The CSS Syntax is background-position : xvalue yvalue; .

"xvalue" and "yvalue" supported values are length units like px and percentage and direction names like left, right and etc .

The "xvalue" is the horizontal position of the background and starts from top of the element . It means if you use 50px it will be "50px" away from top of the elements . And "yvalue" is the vertical position that has the same condition .

So if you use background-position: center; your background image will be centered .

But I always use this code :

.yourclass {_x000D_
  background: url(image.png) no-repeat center /cover;_x000D_
 }

I know it is so confusing but it means :

.yourclass {_x000D_
  background-image: url(image.png);_x000D_
  background-position: center;_x000D_
  background-size: cover;_x000D_
  background-repeat: no-repeat;_x000D_
}

And I know that too the background-size is a new property and in the compressed code what is /cover but these codes means fill background sizing and positioning in windows desktop background .

You can see more details about background-position in here and background-size in here .

Other answers describe the purposes. Here are the characters each function will actually convert:

control = '\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09\x0A\x0B\x0C\x0D\x0E\x0F'
        + '\x10\x11\x12\x13\x14\X15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F'
                                                                    + '\x7F'
encodeURI         (control + ' "%<>[\\]^`{|}'                             )
encodeURIComponent(control + ' "%<>[\\]^`{|}' + '#$&,:;=?' + '+/@'        )
escape            (control + ' "%<>[\\]^`{|}' + '#$&,:;=?' +       "!'()~")

All characters above are converted to percent-hexadecimal codes. Space to %20, percent to %25, etc. The characters below pass through unchanged.

Here are the characters the functions will NOT convert:

pass_thru = '*-._0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'

encodeURI         (pass_thru + '#$&,:;=?' + '+/@' + "!'()~")
encodeURIComponent(pass_thru +                      "!'()~")
escape            (pass_thru +              '+/@'          )

As Uriel says, it is meant for a method in an abstract class that should be implemented in child class, but can be used to indicate a TODO as well.

There is an alternative for the first use case: Abstract Base Classes. Those help creating abstract classes.

Here's a Python 3 example:

class C(abc.ABC):
    @abc.abstractmethod
    def my_abstract_method(self, ...):
        ...

When instantiating C, you'll get an error because my_abstract_method is abstract. You need to implement it in a child class.

TypeError: Can't instantiate abstract class C with abstract methods my_abstract_method

Subclass C and implement my_abstract_method.

class D(C):
    def my_abstract_method(self, ...):
        ...

Now you can instantiate D.

C.my_abstract_method does not have to be empty. It can be called from D using super().

An advantage of this over NotImplementedError is that you get an explicit Exception at instantiation time, not at method call time.

In my context, just developed a class abstraction. When my application is launched, i check if localStorage is working by calling getStorage(). This function also return :

• either localStorage if localStorage is working
• or an implementation of a custom class LocalStorageAlternative

In my code i never call localStorage directly. I call cusStoglobal var, i had initialised by calling getStorage().

This way, it works with private browsing or specific Safari versions

function getStorage() {

    var storageImpl;

     try { 
        localStorage.setItem("storage", ""); 
        localStorage.removeItem("storage");
        storageImpl = localStorage;
     }
     catch (err) { 
         storageImpl = new LocalStorageAlternative();
     }

    return storageImpl;

}

function LocalStorageAlternative() {

    var structureLocalStorage = {};

    this.setItem = function (key, value) {
        structureLocalStorage[key] = value;
    }

    this.getItem = function (key) {
        if(typeof structureLocalStorage[key] != 'undefined' ) {
            return structureLocalStorage[key];
        }
        else {
            return null;
        }
    }

    this.removeItem = function (key) {
        structureLocalStorage[key] = undefined;
    }
}

cusSto = getStorage();

Keep in mind that SQL strings can not be larger than 4000 bytes, while Pl/SQL can have strings as large as 32767 bytes. see below for an example of inserting a large string via an anonymous block which I believe will do everything you need it to do.

note I changed the varchar2(32000) to CLOB

set serveroutput ON 
CREATE TABLE testclob 
  ( 
     id NUMBER, 
     c  CLOB, 
     d  VARCHAR2(4000) 
  ); 

DECLARE 
    reallybigtextstring CLOB := '123'; 
    i                   INT; 
BEGIN 
    WHILE Length(reallybigtextstring) <= 60000 LOOP 
        reallybigtextstring := reallybigtextstring 
                               || '000000000000000000000000000000000'; 
    END LOOP; 

    INSERT INTO testclob 
                (id, 
                 c, 
                 d) 
    VALUES     (0, 
                reallybigtextstring, 
                'done'); 

    dbms_output.Put_line('I have finished inputting your clob: ' 
                         || Length(reallybigtextstring)); 
END; 

/ 
SELECT * 
FROM   testclob; 


 "I have finished inputting your clob: 60030"

A slightly improved answer to BlueFish...

function resizeIframe(iframe) {
    var padding = 50;
    if (iframe.contentWindow.document.body.scrollHeight < (window.innerHeight - padding))
        iframe.height = iframe.contentWindow.document.body.scrollHeight + "px";
    else
        iframe.height = (window.innerHeight - padding) + "px";
}

This takes in consideration the height of the windows screen(browser, phone) which is good for responsive design and iframes that have huge height. Padding represents the padding you want above and below the iframe in the case it goes trough whole screen.

From the documentation on the django model default field:

The default value for the field. This can be a value or a callable object. If callable it will be called every time a new object is created.

Therefore following should work:

date = models.DateTimeField(default=datetime.now,blank=True)

For Retrofit retrofit:2.0.0-beta4 the code goes as follows:

OkHttpClient client = new OkHttpClient.Builder()
    .addInterceptor(logging)
    .connectTimeout(30, TimeUnit.SECONDS)
    .readTimeout(30, TimeUnit.SECONDS)
    .writeTimeout(30, TimeUnit.SECONDS)
    .build();

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl("http://api.yourapp.com/")
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)
    .build();

That's the way to do that: Using OAuth 2.0 for Login.

You may use other authentication methods other then Google's as long as it supports OAuth.

You could overlay one element above the blurred element like so

DEMO

div {
    position: absolute;
    left:0;
    top: 0;
}
p {
    position: absolute;
    left:0;
    top: 0;
}

It's not creating a file because you never actually created the file. You made an object for it. Creating an instance doesn't create the file.

File newFile = new File("directory", "fileName.txt");

You can do this to make a file:

newFile.createNewFile();

You can do this to make a folder:

newFile.mkdir();

Swift 4.2 Extension method

extension UIImage {
    func toBase64() -> String? {
        guard let imageData = self.pngData() else { return nil }
        return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
    }
}

XCode 9.1 and Swift 4.0

//
// Convert UIImage to a base64 representation
//
class func convertImageToBase64(image: UIImage) -> String {
    let imageData = UIImagePNGRepresentation(image)!
    return imageData.base64EncodedString(options: Data.Base64EncodingOptions.lineLength64Characters)
}

//
// Convert a base64 representation to a UIImage
//
class func convertBase64ToImage(imageString: String) -> UIImage {
    let imageData = Data(base64Encoded: imageString, options: Data.Base64DecodingOptions.ignoreUnknownCharacters)!
    return UIImage(data: imageData)!
}

Regarding how you log messages within code, I would opt for the second approach:

ILog log = LogManager.GetLogger(typeof(Bar));
log.Info("message");

Where messages sent to the log above will be 'named' using the fully-qualifed type Bar, e.g.

MyNamespace.Foo.Bar [INFO] message

The advantage of this approach is that it is the de-facto standard for organising logging, it also allows you to filter your log messages by namespace. For example, you can specify that you want to log INFO level message, but raise the logging level for Bar specifically to DEBUG:

<log4net>
    <!-- appenders go here -->
    <root>
        <level value="INFO" />
        <appender-ref ref="myLogAppender" />
    </root>

    <logger name="MyNamespace.Foo.Bar">
        <level value="DEBUG" />
    </logger>
</log4net>

The ability to filter your logging via name is a powerful feature of log4net, if you simply log all your messages to "myLog", you loose much of this power!

Regarding the EPiServer CMS, you should be able to use the above approach to specify a different logging level for the CMS and your own code.

meld 3.14.0

[merge]
    tool = meld
[mergetool "meld"]
    path = C:/Program Files (x86)/Meld/Meld.exe
    cmd = \"C:/Program Files (x86)/Meld/Meld.exe\" --diff \"$BASE\" \"$LOCAL\" \"$REMOTE\" --output \"$MERGED\"

For windows8 right click my pc properties then click environment variables user variable or System variables >> new >> put variable name and path : like this C:\Program Files\nodejs Then ok now open cmd and type npm it will work

You could try using df['column'].str. and then use any string function. Pandas documentation includes those like split

set <ORACLE_HOME> path variable

example

path ORACLE_HOME

value is C:\oraclexe\app\oracle\product\10.2.0\server

Use Regular Expressions, if you are going to somehow extend method's functionality.

Yeah.ios supports RGB valur to range between 0 and 1 only..its close Range [0,1]

$("element").filter(function() { return $(this).css("display") == "none" });

Here is a simple example of converting your List into Spark RDD and then converting that Spark RDD into Dataframe.

Please note that I have used Spark-shell's scala REPL to execute following code, Here sc is an instance of SparkContext which is implicitly available in Spark-shell. Hope it answer your question.

scala> val numList = List(1,2,3,4,5)
numList: List[Int] = List(1, 2, 3, 4, 5)

scala> val numRDD = sc.parallelize(numList)
numRDD: org.apache.spark.rdd.RDD[Int] = ParallelCollectionRDD[80] at parallelize at <console>:28

scala> val numDF = numRDD.toDF
numDF: org.apache.spark.sql.DataFrame = [_1: int]

scala> numDF.show

I recently created a library for creating Gson objects fluently:

http://jglue.org/fluent-json/

It works like this:

  JsonObject jsonObject = JsonBuilderFactory.buildObject() //Create a new builder for an object
  .addNull("nullKey")                            //1. Add a null to the object

  .add("stringKey", "Hello")                     //2. Add a string to the object
  .add("stringNullKey", (String) null)           //3. Add a null string to the object

  .add("numberKey", 2)                           //4. Add a number to the object
  .add("numberNullKey", (Float) null)            //5. Add a null number to the object

  .add("booleanKey", true)                       //6. Add a boolean to the object
  .add("booleanNullKey", (Boolean) null)         //7. Add a null boolean to the object

  .add("characterKey", 'c')                      //8. Add a character to the object
  .add("characterNullKey", (Character) null)     //9. Add a null character to the object

  .addObject("objKey")                           //10. Add a nested object
    .add("nestedPropertyKey", 4)                 //11. Add a nested property to the nested object
    .end()                                       //12. End nested object and return to the parent builder

  .addArray("arrayKey")                          //13. Add an array to the object
    .addObject()                                 //14. Add a nested object to the array
      .end()                                     //15. End the nested object
    .add("arrayElement")                         //16. Add a string to the array
    .end()                                       //17. End the array

    .getJson();                                  //Get the JsonObject

String json = jsonObject.toString();

And through the magic of generics it generates compile errors if you try to add an element to an array with a property key or an element to an object without a property name:

JsonObject jsonArray = JsonBuilderFactory.buildArray().addObject().end().add("foo", "bar").getJson(); //Error: tried to add a string with property key to array.
JsonObject jsonObject = JsonBuilderFactory.buildObject().addArray().end().add("foo").getJson(); //Error: tried to add a string without property key to an object.
JsonArray jsonArray = JsonBuilderFactory.buildObject().addArray("foo").getJson(); //Error: tried to assign an object to an array.
JsonObject jsonObject = JsonBuilderFactory.buildArray().addObject().getJson(); //Error: tried to assign an object to an array.

Lastly there is mapping support in the API which allows you to map your domain objects to JSON. The goal being when Java8 is released you'll be able to do something like this:

Collection<User> users = ...;
JsonArray jsonArray = JsonBuilderFactory.buildArray(users, { u-> buildObject()
                                                                 .add("userName", u.getName())
                                                                 .add("ageInYears", u.getAge()) })
                                                                 .getJson();

I had the same problem today, while I was upgrading some VC6 project to VC2012.

In my case, it was because some of the operation in Custom Built Steps failed. In project properties, go to Custom Build Step, you can see there maybe some something in command line edit box. Open a windows prompt and paste the command to it. Run, check if there is something wrong and fix it.

If there is no command line in the project property Custom Built Step, maybe you should check properties of every single file of the project.

If the command line has some macro, replace it with an actual value.

Or you can echo the command in VS output window:

• cd %(somedir)%
• echo %(somedir)%

You won't miss it this way.

You're going to want to read up on Order of complexity.

http://en.wikipedia.org/wiki/Big_O_notation

In short, O(1) means that it takes a constant time, like 14 nanoseconds, or three minutes no matter the amount of data in the set.

O(n) means it takes an amount of time linear with the size of the set, so a set twice the size will take twice the time. You probably don't want to put a million objects into one of these.

You could use .gitignore to keep the config.xml out of the repository, and then use a post commit hook to upload the appropriate config.xml file to the server.

To get a JSONObject or JSONArray from a String I've created this class:

public static class JSON {

     public Object obj = null;
     public boolean isJsonArray = false;

     JSON(Object obj, boolean isJsonArray){
         this.obj = obj;
         this.isJsonArray = isJsonArray;
     }
}

Here to get the JSON:

public static JSON fromStringToJSON(String jsonString){

    boolean isJsonArray = false;
    Object obj = null;

    try {
        JSONArray jsonArray = new JSONArray(jsonString);
        Log.d("JSON", jsonArray.toString());
        obj = jsonArray;
        isJsonArray = true;
    }
    catch (Throwable t) {
        Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
    }

    if (object == null) {
        try {
            JSONObject jsonObject = new JSONObject(jsonString);
            Log.d("JSON", jsonObject.toString());
            obj = jsonObject;
            isJsonArray = false;
        } catch (Throwable t) {
            Log.e("JSON", "Malformed JSON: \"" + jsonString + "\"");
        }
    }

    return new JSON(obj, isJsonArray);
}

Example:

JSON json = fromStringToJSON("{\"message\":\"ciao\"}");
if (json.obj != null) {

    // If the String is a JSON array
    if (json.isJsonArray) {
        JSONArray jsonArray = (JSONArray) json.obj;
    }
    // If it's a JSON object
    else {
        JSONObject jsonObject = (JSONObject) json.obj;
    }
}

From the documentation of InetAddress.getByName(String host):

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

So you can use it.

A Constant, of any type, can be declared by creating an immutable property that within a class (that is a member variable with the final modifier). Typically the static and public modifiers are also provided.

public class OfficePrinter {
    public static final String STATE = "Ready";  
}

There are numerous applications where a constant's value indicates a selection from an n-tuple (e.g. enumeration) of choices. In our example, we can choose to define an Enumerated Type that will restrict the possible assigned values (i.e. improved type-safety):

public class OfficePrinter {
    public enum PrinterState { Ready, PCLoadLetter, OutOfToner, Offline };
    public static final PrinterState STATE = PrinterState.Ready;
}

The top answer (if e.errno == errno.EPIPE:) here didn't really work for me. I got:

AttributeError: 'BrokenPipeError' object has no attribute 'EPIPE'

However, this ought to work if all you care about is ignoring broken pipes on specific writes. I think it's safer than trapping SIGPIPE:

try:
    # writing, flushing, whatever goes here
except BrokenPipeError:
    exit( 0 )

You obviously have to make a decision as to whether your code is really, truly done if you hit the broken pipe, but for most purposes I think that's usually going to be true. (Don't forget to close file handles, etc.)

Hibernate defines five types of identifier generation strategies:

AUTO - either identity column, sequence or table depending on the underlying DB

TABLE - table holding the id

IDENTITY - identity column

SEQUENCE - sequence

identity copy – the identity is copied from another entity

Example using Table

@Id
@GeneratedValue(strategy=GenerationType.TABLE , generator="employee_generator")
@TableGenerator(name="employee_generator", 
                table="pk_table", 
                pkColumnName="name", 
                valueColumnName="value",                            
                allocationSize=100) 
@Column(name="employee_id")
private Long employeeId;

Use Environment.NewLine whenever you want in any string. An example:

string text = "fkdfdsfdflkdkfk@dfsdfjk72388389@kdkfkdfkkl@jkdjkfjd@jjjk@";

text = text.Replace("@", "@" + System.Environment.NewLine);

Interesting discussion. I was asking myself this question too. The main difference between fluid and fixed is simply that the fixed layout has a fixed width in terms of the whole layout of the website (viewport). If you have a 960px width viewport each colum has a fixed width which will never change.

The fluid layout behaves different. Imagine you have set the width of your main layout to 100% width. Now each column will only be calculated to it's relative size (i.e. 25%) and streches as the browser will be resized. So based on your layout purpose you can select how your layout behaves.

Here is a good article about fluid vs. flex.

You can try this one as well;

tup = (1,2,3)
print("this is a tuple {something}".format(something=tup))

You can't use %something with (tup) just because of packing and unpacking concept with tuple.

find . -mtime -1 -type f -print

You were so close! The kill -HUP method wasn't working for me either.

You were calling:

select @@global.max_connections;

All you needed was to set instead of select:

set @@global.max_connections = 400;

See:

I don't know if this is new functionality, but this will plot on separate figures:

df.plot(y='korisnika')
df.plot(y='osiguranika')

while this will plot on the same figure: (just like the code in the op)

df.plot(y=['korisnika','osiguranika'])

I found this question because I was using the former method and wanted them to plot on the same figure, so your question was actually my answer.

Ctrl + Alt + L works with Android Studio under xfce4 on Linux. I see that Gnome used to use this shortcut for lock screen, but in Gnome 3 it was changed to Super+L (AKA Windows+L): https://wiki.gnome.org/Design/OS/KeyboardShortcuts

You can Use ----

(@item.rigged) ? "Yes" : "No"

If @item.rigged is true, it will return 'Yes' else it will return 'No'

The abort function does this. For example:

abort("Message goes here")

Note: the abort message will be written to STDERR as opposed to puts which will write to STDOUT.

Make sure that all functions with non-void return type have a return statement.

While some compilers automatically provide a default return value, others will send a SIGILL or SIGTRAP at runtime when trying to leave a function without a return value.

This code selects the right tab depending on the #hash and adds the right #hash when a tab is clicked. (this uses jquery)

In Coffeescript :

$(document).ready ->
    if location.hash != ''
        $('a[href="'+location.hash+'"]').tab('show')

    $('a[data-toggle="tab"]').on 'shown', (e) ->
        location.hash = $(e.target).attr('href').substr(1)

or in JS :

$(document).ready(function() {
    if (location.hash !== '') $('a[href="' + location.hash + '"]').tab('show');
    return $('a[data-toggle="tab"]').on('shown', function(e) {
      return location.hash = $(e.target).attr('href').substr(1);
    });
});

@Bill Karwin describes three inheritance models in his SQL Antipatterns book, when proposing solutions to the SQL Entity-Attribute-Value antipattern. This is a brief overview:

Single Table Inheritance (aka Table Per Hierarchy Inheritance):

Using a single table as in your first option is probably the simplest design. As you mentioned, many attributes that are subtype-specific will have to be given a NULL value on rows where these attributes do not apply. With this model, you would have one policies table, which would look something like this:

+------+---------------------+----------+----------------+------------------+
| id   | date_issued         | type     | vehicle_reg_no | property_address |
+------+---------------------+----------+----------------+------------------+
|    1 | 2010-08-20 12:00:00 | MOTOR    | 01-A-04004     | NULL             |
|    2 | 2010-08-20 13:00:00 | MOTOR    | 02-B-01010     | NULL             |
|    3 | 2010-08-20 14:00:00 | PROPERTY | NULL           | Oxford Street    |
|    4 | 2010-08-20 15:00:00 | MOTOR    | 03-C-02020     | NULL             |
+------+---------------------+----------+----------------+------------------+

\------ COMMON FIELDS -------/          \----- SUBTYPE SPECIFIC FIELDS -----/

Keeping the design simple is a plus, but the main problems with this approach are the following:

• When it comes to adding new subtypes, you would have to alter the table to accommodate the attributes that describe these new objects. This can quickly become problematic when you have many subtypes, or if you plan to add subtypes on a regular basis.

• The database will not be able to enforce which attributes apply and which don't, since there is no metadata to define which attributes belong to which subtypes.

• You also cannot enforce NOT NULL on attributes of a subtype that should be mandatory. You would have to handle this in your application, which in general is not ideal.

Concrete Table Inheritance:

Another approach to tackle inheritance is to create a new table for each subtype, repeating all the common attributes in each table. For example:

--// Table: policies_motor
+------+---------------------+----------------+
| id   | date_issued         | vehicle_reg_no |
+------+---------------------+----------------+
|    1 | 2010-08-20 12:00:00 | 01-A-04004     |
|    2 | 2010-08-20 13:00:00 | 02-B-01010     |
|    3 | 2010-08-20 15:00:00 | 03-C-02020     |
+------+---------------------+----------------+
                          
--// Table: policies_property    
+------+---------------------+------------------+
| id   | date_issued         | property_address |
+------+---------------------+------------------+
|    1 | 2010-08-20 14:00:00 | Oxford Street    |   
+------+---------------------+------------------+

This design will basically solve the problems identified for the single table method:

• Mandatory attributes can now be enforced with NOT NULL.

• Adding a new subtype requires adding a new table instead of adding columns to an existing one.

• There is also no risk that an inappropriate attribute is set for a particular subtype, such as the vehicle_reg_no field for a property policy.

• There is no need for the type attribute as in the single table method. The type is now defined by the metadata: the table name.

However this model also comes with a few disadvantages:

• The common attributes are mixed with the subtype specific attributes, and there is no easy way to identify them. The database will not know either.

• When defining the tables, you would have to repeat the common attributes for each subtype table. That's definitely not DRY.

• Searching for all the policies regardless of the subtype becomes difficult, and would require a bunch of UNIONs.

This is how you would have to query all the policies regardless of the type:

SELECT     date_issued, other_common_fields, 'MOTOR' AS type
FROM       policies_motor
UNION ALL
SELECT     date_issued, other_common_fields, 'PROPERTY' AS type
FROM       policies_property;

Note how adding new subtypes would require the above query to be modified with an additional UNION ALL for each subtype. This can easily lead to bugs in your application if this operation is forgotten.

Class Table Inheritance (aka Table Per Type Inheritance):

This is the solution that @David mentions in the other answer. You create a single table for your base class, which includes all the common attributes. Then you would create specific tables for each subtype, whose primary key also serves as a foreign key to the base table. Example:

CREATE TABLE policies (
   policy_id          int,
   date_issued        datetime,

   -- // other common attributes ...
);

CREATE TABLE policy_motor (
    policy_id         int,
    vehicle_reg_no    varchar(20),

   -- // other attributes specific to motor insurance ...

   FOREIGN KEY (policy_id) REFERENCES policies (policy_id)
);

CREATE TABLE policy_property (
    policy_id         int,
    property_address  varchar(20),

   -- // other attributes specific to property insurance ...

   FOREIGN KEY (policy_id) REFERENCES policies (policy_id)
);

This solution solves the problems identified in the other two designs:

• Mandatory attributes can be enforced with NOT NULL.

• Adding a new subtype requires adding a new table instead of adding columns to an existing one.

• No risk that an inappropriate attribute is set for a particular subtype.

• No need for the type attribute.

• Now the common attributes are not mixed with the subtype specific attributes anymore.

• We can stay DRY, finally. There is no need to repeat the common attributes for each subtype table when creating the tables.

• Managing an auto incrementing id for the policies becomes easier, because this can be handled by the base table, instead of each subtype table generating them independently.

• Searching for all the policies regardless of the subtype now becomes very easy: No UNIONs needed - just a SELECT * FROM policies.

I consider the class table approach as the most suitable in most situations.

The names of these three models come from Martin Fowler's book Patterns of Enterprise Application Architecture.

Try SilentCMD. This is a small freeware program that executes a batch file without displaying the command prompt window.

Create a seperate xml file in res/drawable folder

 <?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="1dp" />
    <solid android:color="@android:color/black" />
</shape>

Connect that xml file (your_file) at the main activity, like this:

DividerItemDecoration divider = new DividerItemDecoration(
    recyclerView.getContext(),
    DividerItemDecoration.VERTICAL
);
divider.setDrawable(ContextCompat.getDrawable(getBaseContext(), R.drawable.your_file));
recyclerView.addItemDecoration(divider);

If you thinking like RDBMS, you can't create primary key. Default primary key is _id. But you can create Unique Index. Example is bellow.

db.members.createIndex( { "user_id": 1 }, { unique: true } )

db.members.insert({'user_id':1,'name':'nanhe'})

db.members.insert({'name':'kumar'})

db.members.find();

Output is bellow.

{ "_id" : ObjectId("577f9cecd71d71fa1fb6f43a"), "user_id" : 1, "name" : "nanhe" }

{ "_id" : ObjectId("577f9d02d71d71fa1fb6f43b"), "name" : "kumar" }

When you try to insert same user_id mongodb throws a write error.

db.members.insert({'user_id':1,'name':'aarush'})

WriteResult({ "nInserted" : 0, "writeError" : { "code" : 11000, "errmsg" : "E11000 duplicate key error collection: student.members index: user_id_1 dup key: { : 1.0 }" } })

Well, instead of passing Application.Current.MainWindow, just pass a reference to whichever window it is you want: new WindowInteropHelper(this).Handle and so on.

Or

IIf(CONDITION, TRUE_ACTION, FALSE_ACTION)

You got half of the answer! Now that you created the event handler, you need to hook it to the form so that it actually gets called when the form is loading. You can achieve that by doing the following:

 public class ProgramViwer : Form{
  public ProgramViwer()
  {
       InitializeComponent();
       Load += new EventHandler(ProgramViwer_Load);
  }
  private void ProgramViwer_Load(object sender, System.EventArgs e)
  {
       formPanel.Controls.Clear();
       formPanel.Controls.Add(wel);
  }
}

One should NEVER treat "BLANK" and NULL as the same.

Back in the olden days before there was a SQL standard, Oracle made the design decision that empty strings in VARCHAR/ VARCHAR2 columns were NULL and that there was only one sense of NULL (there are relational theorists that would differentiate between data that has never been prompted for, data where the answer exists but is not known by the user, data where there is no answer, etc. all of which constitute some sense of NULL). By the time that the SQL standard came around and agreed that NULL and the empty string were distinct entities, there were already Oracle users that had code that assumed the two were equivalent. So Oracle was basically left with the options of breaking existing code, violating the SQL standard, or introducing some sort of initialization parameter that would change the functionality of potentially large number of queries. Violating the SQL standard (IMHO) was the least disruptive of these three options.

Oracle has left open the possibility that the VARCHAR data type would change in a future release to adhere to the SQL standard (which is why everyone uses VARCHAR2 in Oracle since that data type's behavior is guaranteed to remain the same going forward).

In the interest of completeness, it should be pointed out that there are representations of strings on various platforms in which the number of bytes per character varies depending on the character. Old-school programmers would refer to this as DBCS (Double Byte Character Set). Modern programmers more commonly encounter this in UTF-8 (as well as UTF-16 and others). There are other such encodings as well.

In any of these variable-width encoding schemes, the simple algorithms posted here (evil, non-evil or otherwise) would not work correctly at all! In fact, they could even cause the string to become illegible or even an illegal string in that encoding scheme. See Juan Pablo Califano's answer for some good examples.

std::reverse() potentially would still work in this case, as long as your platform's implementation of the Standard C++ Library (in particular, string iterators) properly took this into account.

Here's a clue why an onchange() call might not fire your bound function:

http://jehiah.cz/archive/firing-javascript-events-properly

This should work:

for /F "tokens=*" %i in ('temperature') do prismcom.exe usb %i

If running in a batch file, you need to use %%i instead of just %i (in both places).

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

For inserting at a particular position k, you need to traverse the list till the position k-1 and then do the insert.

[You need not create a new node to traverse to that position as you did in your code] You should traverse from the head node.

Normally when you try to select a node using xpath your xpath-engine will return null or equivalent if the node doesn't exists.

xpath: "/Consumers/Consumer/DataSources/Credit/CreditReport/AttachedXml"

If your using xsl check out this question for an answer:

xpath find if node exists

A concise one line:

import java.io.PrintWriter
new PrintWriter("filename") { write("file contents"); close }

Although not as straightforward as isinstance(x, list) one could use as well:

this_is_a_list=[1,2,3]
if type(this_is_a_list) == type([]):
    print("This is a list!")

and I kind of like the simple cleverness of that

So, if you have a statement something like the following, you're saying that you get no 'print' result?

select * from sysobjects
PRINT 'Just selected * from sysobjects'

If you're using SQL Query Analyzer, you'll see that there are two tabs down at the bottom, one of which is "Messages" and that's where the 'print' statements will show up.
If you're concerned about the timing of seeing the print statements, you may want to try using something like

raiserror ('My Print Statement', 10,1) with nowait

This will give you the message immediately as the statement is reached, rather than buffering the output, as the Query Analyzer will do under most conditions.

I want to extend MattMitchell's answer by saying you can create an extension method for this functionality:

public static IsEmptyOrWhitespace(this string value) {
    return String.IsEmptyOrWhitespace(value);
}

This makes it possible to call:

string strValue;
if (strValue.IsEmptyOrWhitespace())
     // do stuff

To me this is a lot cleaner than calling the static String function, while still being NullReference safe!

Ok, at that time got it done with the help of a friend and the code looks like this.

Sub Saving()

Dim part1 As String

Dim part2 As String


part1 = Range("C5").Value

part2 = Range("C8").Value


ActiveWorkbook.SaveAs Filename:= _

"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False

End Sub

How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou

Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?

Keeping your commands short will make them easier to remember:

git log --graph --oneline

Can't comment on Susam Pal's answer but if you're dealing with spaces, I'd surround with quotes:

for f in *.jpg; do mv "$f" "`echo $f | sed s/\ /\-/g`"; done;

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

You had better use find_library command instead of link_directories. Concretely speaking there are two ways:

1. designate the path within the command

   find_library(NAMES gtest PATHS path1 path2 ... pathN)

2. set the variable CMAKE_LIBRARY_PATH

   set(CMAKE_LIBRARY_PATH path1 path2)
   find_library(NAMES gtest)

the reason is as flowings:

Note This command is rarely necessary and should be avoided where there are other choices. Prefer to pass full absolute paths to libraries where possible, since this ensures the correct library will always be linked. The find_library() command provides the full path, which can generally be used directly in calls to target_link_libraries(). Situations where a library search path may be needed include: Project generators like Xcode where the user can switch target architecture at build time, but a full path to a library cannot be used because it only provides one architecture (i.e. it is not a universal binary).

Libraries may themselves have other private library dependencies that expect to be found via RPATH mechanisms, but some linkers are not able to fully decode those paths (e.g. due to the presence of things like $ORIGIN).

If a library search path must be provided, prefer to localize the effect where possible by using the target_link_directories() command rather than link_directories(). The target-specific command can also control how the search directories propagate to other dependent targets.

UPDATE: Added C# code, and link to Windows Jobs

I spent sometime trying to figure out this problem, and at the time XtremeVBTalk was the most active and responsive. Here is a link to my original post, Closing an Excel Interop process cleanly, even if your application crashes. Below is a summary of the post, and the code copied to this post.

• Closing the Interop process with Application.Quit() and Process.Kill() works for the most part, but fails if the applications crashes catastrophically. I.e. if the app crashes, the Excel process will still be running loose.
• The solution is to let the OS handle the cleanup of your processes through Windows Job Objects using Win32 calls. When your main application dies, the associated processes (i.e. Excel) will get terminated as well.

I found this to be a clean solution because the OS is doing real work of cleaning up. All you have to do is register the Excel process.

Windows Job Code

Wraps the Win32 API Calls to register Interop processes.

        IntPtr extendedInfoPtr = Marshal.AllocHGlobal(length);
        Marshal.StructureToPtr(extendedInfo, extendedInfoPtr, false);

        if (!SetInformationJobObject(m_handle, JobObjectInfoType.ExtendedLimitInformation, extendedInfoPtr, (uint)length))
            throw new Exception(string.Format("Unable to set information.  Error: {0}", Marshal.GetLastWin32Error()));

    private void Dispose(bool disposing)
    {

            return;

        if (disposing) {}

        Close();

    }

    public bool AddProcess(IntPtr handle)
    {
        return AssignProcessToJobObject(m_handle, handle);
    }

}

Note about Constructor code

• In the constructor, the info.LimitFlags = 0x2000; is called. 0x2000 is the JOB_OBJECT_LIMIT_KILL_ON_JOB_CLOSE enum value, and this value is defined by MSDN as:

Causes all processes associated with the job to terminate when the last handle to the job is closed.

Extra Win32 API Call to get the Process ID (PID)

    [DllImport("user32.dll", SetLastError = true)]
    public static extern uint GetWindowThreadProcessId(IntPtr hWnd, out uint lpdwProcessId);

Using the code

    Excel.Application app = new Excel.ApplicationClass();
    Job job = new Job();
    uint pid = 0;
    Win32.GetWindowThreadProcessId(new IntPtr(app.Hwnd), out pid);
    job.AddProcess(Process.GetProcessById((int)pid).Handle);

I prefer to this way:

   /**
     *
     * @param host
     * @return true means ping success,false means ping fail.
     * @throws IOException
     * @throws InterruptedException
     */
    private static boolean ping(String host) throws IOException, InterruptedException {
        boolean isWindows = System.getProperty("os.name").toLowerCase().contains("win");

        ProcessBuilder processBuilder = new ProcessBuilder("ping", isWindows? "-n" : "-c", "1", host);
        Process proc = processBuilder.start();
        return proc.waitFor(200, TimeUnit.MILLISECONDS);
    }

This way can limit the blocking time to the specific time,such as 200 ms.

It works well in MacOS?Android and Windows, but should used in JDK 1.8.

This idea comes from Mohammad Banisaeid,but I can't comment. (You must have 50 reputation to comment)

There are many ways to create re-usable objects like this in JavaScript. Mozilla have a nice introduction here:

• https://developer.mozilla.org/en-US/docs/JavaScript/Introduction_to_Object-Oriented_JavaScript

The following will work in your example:

function Foo(){
    this.bar = function (){
        alert("Hello World!");
    }
}

myFoo = new Foo();
myFoo.bar(); // Hello World?????????????????????????????????

On my projects i give all rows the class "borders" which I want it to display more like a table with even borders. Giving each child element a border on the bottom and right and the first element of each row a left border will make all of your boxes have an even border:

First give all of the rows children a border on the right and bottom

.borders div{
    border-right:1px solid #999;
    border-bottom:1px solid #999;
}

Next give the first child of each or a left border

.borders div:first-child{
    border-left:
    1px solid #999;
}

Last make sure to clear the borders for their child elements

.borders div > div{
    border:0;
}

HTML:

<div class="row borders">
    <div class="col-xs-5 col-md-2">Email</div>
    <div class="col-xs-7 col-md-4">[email protected]</div>
    <div class="col-xs-5 col-md-2">Phone</div>
    <div class="col-xs-7 col-md-4">555-123-4567</div>
</div>

SELECT TABLE_NAME AS "Table Name", 
table_rows AS "Quant of Rows", ROUND( (
data_length + index_length
) /1024, 2 ) AS "Total Size Kb"
FROM information_schema.TABLES
WHERE information_schema.TABLES.table_schema = 'YOUR SCHEMA NAME/DATABASE NAME HERE'
LIMIT 0 , 30

You can get schema name from "information_schema" -> SCHEMATA table -> "SCHEMA_NAME" column

Additional You can get size of the mysql databases as following.

SELECT table_schema "DB Name", 
Round(Sum(data_length + index_length) / 1024 / 1024, 1) "DB Size in MB" 
FROM   information_schema.tables 
GROUP  BY table_schema; 

Result

DB Name              |      DB Size in MB

mydatabase_wrdp             39.1
information_schema          0.0

You can get additional details in here.

Well there is quick to run a html which needs permission or blocked by CORS Just simply open the folder using VSCODE and install an extension called "live server"

And then just click on the bottom which says go live, thats it. Screenshot

You can use assertThrows(). My example is taken from the docs http://junit.org/junit5/docs/current/user-guide/

import org.junit.jupiter.api.Test;

import static org.junit.jupiter.api.Assertions.assertEquals;
import static org.junit.jupiter.api.Assertions.assertThrows;

....

@Test
void exceptionTesting() {
    Throwable exception = assertThrows(IllegalArgumentException.class, () -> {
        throw new IllegalArgumentException("a message");
    });
    assertEquals("a message", exception.getMessage());
}

Ahem...

The short answer to your question is that you must set the height of 100% to the body and html tag, then set the height to 100% on each div element you want to make 100% the height of the page.

Actually, 100% height will not work in most design situations - this may be short but it is not a good answer. Google "any column longest" layouts. The best way is to put the left and right cols inside a wrapper div, float the left and right cols and then float the wrapper - this makes it stretch to the height of the inner containers - then set background image on the outer wrapper. But watch for any horizontal margins on the floated elements in case you get the IE "double margin float bug".

This is the JsonParser class

public class JSONParser {

    static InputStream is = null;
    static JSONObject jObj = null;
    static String json = "";

    // constructor
    public JSONParser() {

    }

    public JSONObject getJSONFromUrl(String url) {

        // Making HTTP request
        try {
            // defaultHttpClient
            DefaultHttpClient httpClient = new DefaultHttpClient();
            HttpPost httpPost = new HttpPost(url);

            HttpResponse httpResponse = httpClient.execute(httpPost);

            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            json = sb.toString();
        } catch (Exception e) {
            Log.e("Buffer Error", "Error converting result " + e.toString());
        }

        // try parse the string to a JSON object
        try {
            jObj = new JSONObject(json);
        } catch (JSONException e) {
            Log.e("JSON Parser", "Error parsing data " + e.toString());
        }

        // return JSON String
        return jObj;

    }

Note: DefaultHttpClient is no longer supported by sdk 23, so it is advisable to use target sdk 21 with this code.

The above answers provided are perfect. The LF(\n), CR(\r) and CRLF(\r\n) characters are platform dependent. However, the interpretation for these characters is not only defined by the platforms but also the console that you are using. In Intellij console (Windows), this \r character in this statement System.out.print("Happ\ry"); produces the output y. But, if you use the terminal (Windows), you will get yapp as the output.

Try this:

@echo off
setlocal
cd /d %~dp0
Call :UnZipFile "C:\Temp\" "c:\path\to\batch.zip"
exit /b

:UnZipFile <ExtractTo> <newzipfile>
set vbs="%temp%\_.vbs"
if exist %vbs% del /f /q %vbs%
>%vbs%  echo Set fso = CreateObject("Scripting.FileSystemObject")
>>%vbs% echo If NOT fso.FolderExists(%1) Then
>>%vbs% echo fso.CreateFolder(%1)
>>%vbs% echo End If
>>%vbs% echo set objShell = CreateObject("Shell.Application")
>>%vbs% echo set FilesInZip=objShell.NameSpace(%2).items
>>%vbs% echo objShell.NameSpace(%1).CopyHere(FilesInZip)
>>%vbs% echo Set fso = Nothing
>>%vbs% echo Set objShell = Nothing
cscript //nologo %vbs%
if exist %vbs% del /f /q %vbs%

Revision

To have it perform the unzip on each zip file creating a folder for each use:

@echo off
setlocal
cd /d %~dp0
for %%a in (*.zip) do (
    Call :UnZipFile "C:\Temp\%%~na\" "c:\path\to\%%~nxa"
)
exit /b

If you don't want it to create a folder for each zip, change Call :UnZipFile "C:\Temp\%%~na\" "c:\path\to\%%~nxa" to Call :UnZipFile "C:\Temp\" "c:\path\to\%%~nxa"

say you define the static getFactorial function inside a CodeController

then this is the way you need to call a static function, because static properties and methods exists with in the class, not in the objects created using the class.

CodeController::getFactorial($index);

----------------UPDATE----------------

To best practice I think you can put this kind of functions inside a separate file so you can maintain with more easily.

to do that

create a folder inside app directory and name it as lib (you can put a name you like).

this folder to needs to be autoload to do that add app/lib to composer.json as below. and run the composer dumpautoload command.

"autoload": {
    "classmap": [
                "app/commands",
                "app/controllers",
                ............
                "app/lib"
    ]
},

then files inside lib will autoloaded.

then create a file inside lib, i name it helperFunctions.php

inside that define the function.

if ( ! function_exists('getFactorial'))
{

    /**
     * return the factorial of a number
     *
     * @param $number
     * @return string
     */
    function getFactorial($date)
    {
        $fact = 1;

        for($i = 1; $i <= $num ;$i++)
            $fact = $fact * $i;

        return $fact;

     }
}

and call it anywhere within the app as

$fatorial_value = getFactorial(225);

The selected answer didn't work for me, but it's close. I found a tutorial that worked for me and the certificate I obtained from StartCom.

1. Open the .p7b in a text editor.

2. Change the leader and trailer so the file looks similar to this:

   -----BEGIN PKCS7-----
   [... certificate content here ...]
   -----END PKCS7-----
   

For example, my StartCom certificate began with:

    -----BEGIN CERTIFICATE----- 

and ended with:

    -----END CERTIFICATE----- 

3. Save and close the .p7b.

4. Run the following OpenSSL command (works on Ubuntu 14.04.4, as of this writing):

   openssl pkcs7 -print_certs –in pkcs7.p7b -out pem.cer
   

The output is a .cer with the certificate chain.

You might wanna clear the old Image before setting a new Image.

You also need to update the Canvas size for a new Image.

This is how I am doing in my project:

    this.image.onload = () => {

      // Clear Old Image and Reset Bounds
      canvasContext.clearRect(0, 0, this.canvas.width, this.canvas.height);
      this.canvas.height = this.image.height;
      this.canvas.width = this.image.width;

      // Redraw Image
      canvasContext.drawImage(
        this.image,
        0,
        0,
        this.image.width,
        this.image.height
      );
    };

1. Create new text file in your wp-admin directory root and name it info.php.

2. Open info.php and add this line:

   <?php phpinfo(); ?>

3. Save it.

4. Go to yourwebsitename(probably localhost)/wp-admin/info.php in any web-browser.

5. On the 8th line you will see: Configuration File (php.ini) Path, in my case it is C:\Windows, meaning it is located on my C drive.

6. In the 9th line you will see: Loaded Configuration File, and next to it is written C:\xampp\php.ini

So I found my php.ini page that is associated with my wordpress web-site.

7. Go to that path, and find php.ini.

8. Open it, and edit:

   Search for post_max_size=8M, and change it to post_max_size=1000M

   Search for upload_max_filesize=2M, and change it to upload_max_filesize=1000M

9. Go back to your Admin page ? Media ? Add New

10. On the bottom you will see that 2MB has changed to 1000M.

Once you done this process then you must restart your web server or just restart your computer.

Use grep as follows:

grep -R "touch" .

-R means recurse. If you would rather not go into the subdirectories, then skip it.

-i means "ignore case". You might find this worth a try as well.

This answer does not work anymore, but I'm looking for a solution.

As of . 2015 / 02 / 24 . there is a website (youtubeinmp4) that allows you to download youtube videos in .mp4 format, you can exploit this (with some JavaScript) to get away with embedding youtube videos in <video> tags. Here is a demo of this in action.

##Pros

• Fairly easy to implement.
• Quite fast server response actually (it doesn't take that much to retrieve the videos).
• Abstraction (the accepted solution, even if it worked properly, would only be applicable if you knew beforehand which videos you were going to play, this works for any user inputted url).

##Cons

• It obviously depends on the youtubeinmp4.com servers and their way of providing a downloading link (which can be passed as a <video> source), so this answer may not be valid in the future.

• You can't choose the video quality.

###JavaScript (after load)

videos = document.querySelectorAll("video");
for (var i = 0, l = videos.length; i < l; i++) {
    var video = videos[i];
    var src = video.src || (function () {
        var sources = video.querySelectorAll("source");
        for (var j = 0, sl = sources.length; j < sl; j++) {
            var source = sources[j];
            var type = source.type;
            var isMp4 = type.indexOf("mp4") != -1;
            if (isMp4) return source.src;
        }
        return null;
    })();
    if (src) {
        var isYoutube = src && src.match(/(?:youtu|youtube)(?:\.com|\.be)\/([\w\W]+)/i);
        if (isYoutube) {
            var id = isYoutube[1].match(/watch\?v=|[\w\W]+/gi);
            id = (id.length > 1) ? id.splice(1) : id;
            id = id.toString();
            var mp4url = "http://www.youtubeinmp4.com/redirect.php?video=";
            video.src = mp4url + id;
        }
    }
}

###Usage (Full)

<video controls="true">
        <source src="www.youtube.com/watch?v=3bGNuRtlqAQ" type="video/mp4" />
    </video>

Standard video format.

###Usage (Mini)

<video src="youtu.be/MLeIBFYY6UY" controls="true"></video>

A little less common but quite smaller, using the shortened url youtu.be as the src attribute directly in the <video> tag.

The other answers above have answered your first question. As for your second question, how to detect an error of getting a value that is not set, I am not sure which of the following situation you mean:

1. Accessing an array element using an invalid index:
   If you use std::vector, you can use vector::at function instead of [] operator to get the value, if the index is invalid, an out_of_range exception will be thrown.

2. Accessing a valid index, but the element has not been set yet: As far as I know, there is no direct way of it. However, the following common practices can probably solve you problem: (1) Initializes all elements to a value that you are certain that is impossible to have. For example, if you are dealing with positive integers, set all elements to -1, so you know the value is not set yet when you find it being -1. (2). Simply use a bool array of the same size to indicate whether the element of the same index is set or not, this applies when all values are "possible".

For those who are able to access cpanel, there is a simpler way getting around it.

1. log in cpanel => "Remote MySQL" under DATABASES section:

2. Add the IPs / hostname which you are accessing from

3. done!!!

You can use the backslash to include both the story and the players name in one line.

var name=prompt("what is your name?"); console.log("story"\name\"story");

Inside styles.xml...

<!-- No action bar -->
<style name="NoActonBar" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Theme customization. -->
    <item name="colorPrimary">#000</item>
    <item name="colorPrimaryDark">#444</item>
    <item name="colorAccent">#999</item>
    <item name="android:windowFullscreen">true</item>
</style>

This worked for me. Hope it'll help you.

There's a way you can do this.

You will need ROOT access to edit the following file.

Navigate to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS4.2.sdk and open the file SDKSettings.plist.

In that file, expand DefaultProperties and change CODE_SIGNING_REQUIRED to NO, while you are there, you can also change ENTITLEMENTS_REQUIRED to NO also.

You will have to restart Xcode for the changes to take effect. Also, you must do this for every .sdk you want to be able to run on device.

Now, in your project settings, you can change Code Signing Identity to Don't Code Sign.

Your app should now build and install on your device successfully.

UPDATE:

There are some issues with iOS 5.1 SDK that this method may not work exactly the same. Any other updates will be listed here when they become available.

UPDATE:

You can find the correct path to SDKSettings.plist with xcrun.

xcrun --sdk iphoneos --show-sdk-path

New SDKSettings.plist location for the iOS 5.1 SDK:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk/SDKSettings.plist

 import sys
 sys.path.append('your certain directory')

Basically sys.path is a list with all the search paths for python modules. It is initialized by the interpreter. The content of PYTHONPATH is automatically added to the end of that list.

Personally I think Thread.Sleep is a poor implementation. It locks the UI etc. I personally like timer implementations since it waits then fires.

Usage: DelayFactory.DelayAction(500, new Action(() => { this.RunAction(); }));

//Note Forms.Timer and Timer() have similar implementations. 

public static void DelayAction(int millisecond, Action action)
{
    var timer = new DispatcherTimer();
    timer.Tick += delegate

    {
        action.Invoke();
        timer.Stop();
    };

    timer.Interval = TimeSpan.FromMilliseconds(millisecond);
    timer.Start();
}

There is a vcvars32.bat in your Visual Studio installation directory. You can add call cmd.exe at the end of that batch program and launch it. From that shell you can use CMake or cmake-gui and cl.exe would be known to CMake.

Follow these two simple steps and get increase height of your UItextField.

Step 1: right click on XIB file and open it as in "Source Code".

Step 2: Find the same UITextfield source and set the frame as you want.

You can use these steps to change frame of any apple controls.

The thread is a little old, I know, but for future reference and for noobs as myself:

Everyone else here explain how to create the CSV, but miss a basic part of the question: how to link. In order to link to download of the CSV-file, you just link to the .php-file, which in turn responds as being a .csv-file. The PHP headers do that. This enables cool stuff, like adding variables to the querystring and customize the output:

<a href="my_csv_creator.php?user=23&amp;othervariable=true">Get CSV</a>

my_csv_creator.php can work with the variables given in the querystring and for example use different or customized database queries, change the columns of the CSV, personalize the filename and so on, e.g.:

User_John_Doe_10_Dec_11.csv

Closures provide JavaScript with state.

State in programming simply means remembering things.

Example

var a = 0;

a = a + 1; // => 1
a = a + 1; // => 2
a = a + 1; // => 3

In the case above, state is stored in the variable "a". We follow by adding 1 to "a" several times. We can only do that because we are able to "remember" the value. The state holder, "a", holds that value in memory.

Often, in programming languages, you want to keep track of things, remember information and access it at a later time.

This, in other languages, is commonly accomplished through the use of classes. A class, just like variables, keeps track of its state. And instances of that class, in turns, also have state within them. State simply means information that you can store and retrieve later.

Example

class Bread {
  constructor (weight) {
    this.weight = weight;
  }

  render () {
    return `My weight is ${this.weight}!`;
  }
}

How can we access "weight" from within the "render" method? Well, thanks to state. Each instance of the class Bread can render its own weight by reading it from the "state", a place in memory where we could store that information.

Now, JavaScript is a very unique language which historically does not have classes (it now does, but under the hood there's only functions and variables) so Closures provide a way for JavaScript to remember things and access them later.

Example

var n = 0;
var count = function () {
  n = n + 1;
  return n;
};

count(); // # 1
count(); // # 2
count(); // # 3

The example above achieved the goal of "keeping state" with a variable. This is great! However, this has the disadvantage that the variable (the "state" holder) is now exposed. We can do better. We can use Closures.

Example

var countGenerator = function () {
  var n = 0;
  var count = function () {
    n = n + 1;
    return n;
  };

  return count;
};

var count = countGenerator();
count(); // # 1
count(); // # 2
count(); // # 3

This is fantastic.

Now our "count" function can count. It is only able to do so because it can "hold" state. The state in this case is the variable "n". This variable is now closed. Closed in time and space. In time because you won't ever be able to recover it, change it, assign it a value or interact directly with it. In space because it's geographically nested within the "countGenerator" function.

Why is this fantastic? Because without involving any other sophisticated and complicated tool (e.g. classes, methods, instances, etc) we are able to 1. conceal 2. control from a distance

We conceal the state, the variable "n", which makes it a private variable! We also have created an API that can control this variable in a pre-defined way. In particular, we can call the API like so "count()" and that adds 1 to "n" from a "distance". In no way, shape or form anyone will ever be able to access "n" except through the API.

JavaScript is truly amazing in its simplicity.

Closures are a big part of why this is.

Just to offer you a different angle -

I find it's not a good idea to maintain public variables between function calls. Any variables you need to use should be stored in Subs and Functions and passed as parameters. Once the code is done running, you shouldn't expect the VBA Project to maintain the values of any variables.

The reason for this is that there is just a huge slew of things that can inadvertently reset the VBA Project while using the workbook. When this happens, any public variables get reset to 0.

If you need a value to be stored outside of your subs and functions, I highly recommend using a hidden worksheet with named ranges for any information that needs to persist.

Website:

The Web Site project is compiled on the fly. You end up with a lot more DLL files, which can be a pain. It also gives problems when you have pages or controls in one directory that need to reference pages and controls in another directory since the other directory may not be compiled into the code yet. Another problem can be in publishing.

If Visual Studio isn't told to re-use the same names constantly, it will come up with new names for the DLL files generated by pages all the time. That can lead to having several close copies of DLL files containing the same class name, which will generate plenty of errors. The Web Site project was introduced with Visual Studio 2005, but it has turned out not to be popular.

Web Application:

The Web Application Project was created as an add-in and now exists as part of SP 1 for Visual Studio 2005. The main differences are the Web Application Project was designed to work similarly to the Web projects that shipped with Visual Studio 2003. It will compile the application into a single DLL file at build time. To update the project, it must be recompiled and the DLL file published for changes to occur.

Another nice feature of the Web Application project is it's much easier to exclude files from the project view. In the Web Site project, each file that you exclude is renamed with an excluded keyword in the filename. In the Web Application Project, the project just keeps track of which files to include/exclude from the project view without renaming them, making things much tidier.

Reference

The article ASP.NET 2.0 - Web Site vs Web Application project also gives reasons on why to use one and not the other. Here is an excerpt of it:

• You need to migrate large Visual Studio .NET 2003 applications to VS 2005? use the Web Application project.
• You want to open and edit any directory as a Web project without creating a project file? use Web Site project.
• You need to add pre-build and post-build steps during compilation? use Web Application project.
• You need to build a Web application using multiple Web projects? use the Web Application project.
• You want to generate one assembly for each page? use the Web Site project.
• You prefer dynamic compilation and working on pages without building entire site on each page view? use Web Site project.
• You prefer single-page code model to code-behind model? use Web Site project.

Web Application Projects versus Web Site Projects (MSDN) explains the differences between the web site and web application projects. Also, it discusses the configuration to be made in Visual Studio.

One possible approach, if you just need to specify a parameter once and replicate it in several places, is to do something like this:

SELECT
  str_size  /* my variable usage */
  , LPAD(TRUNC(DBMS_RANDOM.VALUE * POWER(10, str_size)), str_size, '0') rand
FROM
  dual  /* or any other table, or mixed of joined tables */
  CROSS JOIN (SELECT 8 str_size FROM dual);  /* my variable declaration */

This code generates a string of 8 random digits.

Notice that I create a kind of alias named str_size that holds the constant 8. It is cross-joined to be used more than once in the query.

Instead of using the pyodbc library, use the pypyodbc library... This worked for me.

import pypyodbc

conn = pypyodbc.connect("DRIVER={SQL Server};"
                    "SERVER=server;"
                    "DATABASE=database;"
                    "Trusted_Connection=yes;")

cursor = conn.cursor()
cursor.execute('SELECT * FROM [table]')

for row in cursor:
    print('row = %r' % (row,))

If you were using C# 4, you could make use of the new dynamic functionality to achieve an interesting alternative. I'm not saying this is better, in fact it seems very likely that it would be slower, but it does have a certain elegance to it.

class Thing
{

  void Foo(A a)
  {
     a.Hop();
  }

  void Foo(B b)
  {
     b.Skip();
  }

}

And the usage:

object aOrB = Get_AOrB();
Thing t = GetThing();
((dynamic)t).Foo(aorB);

The reason this works is that a C# 4 dynamic method invocation has its overloads resolved at runtime rather than compile time. I wrote a little more about this idea quite recently. Again, I would just like to reiterate that this probably performs worse than all the other suggestions, I am offering it simply as a curiosity.

rake tmp:cache:clear might be what you're looking for.

I took a lot of time to solve this error! Run command

pip install opencv-contrib-python

The csv.writer writerow method takes an iterable as an argument. Your result set has to be a list (rows) of lists (columns).

csvwriter.writerow(row)

Write the row parameter to the writer’s file object, formatted according to the current dialect.

Do either:

import csv
RESULTS = [
    ['apple','cherry','orange','pineapple','strawberry']
]
with open('output.csv','wb') as result_file:
    wr = csv.writer(result_file, dialect='excel')
    wr.writerows(RESULTS)

or:

import csv
RESULT = ['apple','cherry','orange','pineapple','strawberry']
with open('output.csv','wb') as result_file:
    wr = csv.writer(result_file, dialect='excel')
    wr.writerow(RESULT)

You can use this.innerHTML.

<textarea name="message" rows = "10" cols = "100" onfocus="this.innerHTML=''"> Enter your message here... </textarea>

When text area is focused, it basically makes the innerHTML of the textarea an empty string.

                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">

Use the where command. The first result in the list is the one that will execute.

C:\> where notepad
C:\Windows\System32\notepad.exe
C:\Windows\notepad.exe

According to this blog post, where.exe is included with Windows Server 2003 and later, so this should just work with Vista, Win 7, et al.

On Linux, the equivalent is the which command, e.g. which ssh.

You could use this recursive function for generate necessary T-SQL script.

if you don't know the value of XML Element, you can use

$value = (string) $xml->code[0]->lat;

if (ctype_digit($value)) {
    // the value is probably an integer because consists only of digits
}

It works when you need to determine if value is a number, because (string) will always return string and is_int($value) returns false

Trailing whitespace is any spaces or tabs after the last non-whitespace character on the line until the newline.

In your posted question, there is one extra space after try:, and there are 12 extra spaces after pass:

>>> post_text = '''\
...             if self.tagname and self.tagname2 in list1:
...                 try: 
...                     question = soup.find("div", "post-text")
...                     title = soup.find("a", "question-hyperlink")
...                     self.list2.append(str(title)+str(question)+url)
...                     current += 1
...                 except AttributeError:
...                     pass            
...             logging.info("%s questions passed, %s questions \
...                 collected" % (count, current))
...             count += 1
...         return self.list2
... '''
>>> for line in post_text.splitlines():
...     if line.rstrip() != line:
...         print(repr(line))
... 
'                try: '
'                    pass            '

See where the strings end? There are spaces before the lines (indentation), but also spaces after.

Use your editor to find the end of the line and backspace. Many modern text editors can also automatically remove trailing whitespace from the end of the line, for example every time you save a file.

I think df['word'].value_counts() should serve. By skipping the groupby machinery, you'll save some time. I'm not sure why count should be much slower than max. Both take some time to avoid missing values. (Compare with size.)

In any case, value_counts has been specifically optimized to handle object type, like your words, so I doubt you'll do much better than that.

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

For this example we take it for granted that varcharcol doesn't contain '' and have no empty cell against this column

select * from some_table where varcharCol = ''
select * from some_table where varcharCol like ''

The first one results in 0 row output while the second one shows the whole list. = is strictly-match case while like acts like a filter. if filter has no criteria, every data is valid.

like - by the virtue of its purpose works a little slower and is intended for use with varchar and similar data.

You can use like this also,

<a href="javascript:void(0);" onclick="javascript:window.location.href='mailto:[email protected]'; return false;">[email protected]</a>

I think this is best way to resolved for chrome issues.

Thanks..

Here's a cool one that I use in a ruby script on OS X (so that I can start a script and get an update even after toggling away from the window):

cmd = %Q|osascript -e 'display notification "Server was reset" with title "Posted Update"'|
system ( cmd )

Principled Design of the Modern Web Architecture by Roy T. Fielding and Richard N. Taylor, i.e. sequence of works from all REST terminology came from, contains definition of client-server interaction:

All REST interactions are stateless. That is, each request contains all of the information necessary for a connector to understand the request, independent of any requests that may have preceded it.

This restriction accomplishes four functions, 1st and 3rd are important in this particular case:

• 1st: it removes any need for the connectors to retain application state between requests, thus reducing consumption of physical resources and improving scalability;
• 3rd: it allows an intermediary to view and understand a request in isolation, which may be necessary when services are dynamically rearranged;

And now lets go back to your security case. Every single request should contains all required information, and authorization/authentication is not an exception. How to achieve this? Literally send all required information over wires with every request.

One of examples how to archeive this is hash-based message authentication code or HMAC. In practice this means adding a hash code of current message to every request. Hash code calculated by cryptographic hash function in combination with a secret cryptographic key. Cryptographic hash function is either predefined or part of code-on-demand REST conception (for example JavaScript). Secret cryptographic key should be provided by server to client as resource, and client uses it to calculate hash code for every request.

There are a lot of examples of HMAC implementations, but I'd like you to pay attention to the following three:

• Authenticating REST Requests for Amazon Simple Storage Service (Amazon S3)
• Answer by Mauriceless on quiestion: "How to implement HMAC Authentication in a RESTful WCF API"
• crypto-js: JavaScript implementations of standard and secure cryptographic algorithms

How it works in practice

If client knows the secret key, then it's ready to operate with resources. Otherwise he will be temporarily redirected (status code 307 Temporary Redirect) to authorize and to get secret key, and then redirected back to the original resource. In this case there is no need to know beforehand (i.e. hardcode somewhere) what the URL to authorize the client is, and it possible to adjust this schema with time.

Hope this will helps you to find the proper solution!

~/In_ProjectDirectory $ g++ coordin_main.cpp coordin_func.cpp coordin.h

~/In_ProjectDirectory $ ./a.out

... Worked!!

Using Linux Mint with Geany IDE

When I saved each file to the same directory, one file was not saved correctly within the directory; the coordin.h file. So, rechecked and it was saved there as coordin.h, and not incorrectly as -> coordin.h.gch. The little stuff. Arg!!

You need to have

#include <string>

in the header file too.The forward declaration on it's own doesn't do enough.

Also strongly consider header guards for your header files to avoid possible future problems as your project grows. So at the top do something like:

#ifndef THE_FILE_NAME_H
#define THE_FILE_NAME_H

/* header goes in here */

#endif

This will prevent the header file from being #included multiple times, if you don't have such a guard then you can have issues with multiple declarations.

Gitg is a clone of Gitk and GitX for GNOME (it also works on KDE etc.) which shows a pretty colored graph.

It is actively developed (as of 2012). It lets you sort the commits (graph nodes) either chronologically or topologically, and hide commits that don't lead to a selected branch.

It works fine with large repositories and complex dependency graphs.

Try the command FLUSH PRIVILEGES when you log into the MySQL terminal. If that doesn't work, try the following set of commands while in the MySQL terminal

$ mysql -u root
mysql> USE mysql;
mysql> UPDATE user SET password=PASSWORD("NEWPASSWORD") WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit

Change out NEWPASSWORD with whatever password you want. Should be all set!

Update: As of MySQL 5.7, the password field has been renamed authentication_string. When changing the password, use the following query to change the password. All other commands remain the same:

mysql> UPDATE user SET authentication_string=PASSWORD("NEWPASSWORD") WHERE User='root';

Update: On 8.0.15 (maybe already before that version) the PASSWORD() function does not work, as mentioned in the comments below. You have to use:

UPDATE mysql.user SET authentication_string='password' WHERE User='root';

if you don't want the field to look "disabled" or smth, just use this:

onkeydown="return false;"

it's basically the same that greengit and Derek said but a little shorter

The problems is that dropboxes don't work the same as listboxes, at least the way ASP.NET MVC2 design expects: A dropbox allows only zero or one values, as listboxes can have a multiple value selection. So, being strict with HTML, that value shouldn't be in the option list as "selected" flag, but in the input itself.

See the following example:

<select id="combo" name="combo" value="id2">
  <option value="id1">This is option 1</option>
  <option value="id2" selected="selected">This is option 2</option>
  <option value="id3">This is option 3</option>
</select>

<select id="listbox" name="listbox" multiple>
  <option value="id1">This is option 1</option>
  <option value="id2" selected="selected">This is option 2</option>
  <option value="id3">This is option 3</option>
</select>

The combo has the option selected, but also has its value attribute set. So, if you want ASP.NET MVC2 to render a dropbox and also have a specific value selected (i.e., default values, etc.), you should give it a value in the rendering, like this:

// in my view             
<%=Html.DropDownList("UserId", selectListItems /* (SelectList)ViewData["UserId"]*/, new { @Value = selectedUser.Id } /* Your selected value as an additional HTML attribute */)%>

Be aware that passing an Object with named properties as Ken suggested adds the cost of allocating and releasing the temporary object to every call. Passing normal arguments by value or reference will generally be the most efficient. For many applications though the performance is not critical but for some it can be.

Rather than querying the DOM for elements (which isn't very angular see "Thinking in AngularJS" if I have a jQuery background?) you should perform your DOM manipulation within your directive. The element is available to you in your link function.

So in your myDirective

return {
    link: function (scope, element, attr) {
        element.html('Hello world');
    }
}

If you must perform the query outside of the directive then it would be possible to use querySelectorAll in modern browers

angular.element(document.querySelectorAll("[my-directive]"));

however you would need to use jquery to support IE8 and backwards

angular.element($("[my-directive]"));

or write your own method as demonstrated here Get elements by attribute when querySelectorAll is not available without using libraries?

Back in 2010 we had the same problem and i successfully employed GoogleDocs with our small Agile Development team (8 Devs in 3 Countries).

GoogleDrawing will serve in the exact same way as a physical Scrum board would, with all the upsides of full flexibilty and also the downsides of zero automation but with the big additional upside of being virtual and accessible from anywhere with an internet connection.

It also was used for the retrospective at the end of each Sprint

GoogleSpreadsheet was used for a concise list of all the tickets from our bug tracking system (Redmine, manually transfered) and also for the (manually updated, albeit with formulas to calculate the progress) burndown chart.

The combination of these different elements is actually quite powerful, as you have the full flexibility over the content and its representation and can have your team communicate via VoIP while all are looking at the same documents and can modify them in real-time.

Here an example of the docs used in a sprint (all sensitive data removed):

• Scrum board Example (GoogleDrawing)
• Retrospective Example (GoogleDrawing)
• Burndown Chart Example (GoogleSheet, formulas to automate calculation)
• Ticket list from Bugtracker (GoogleSheet)

As mentioned before, the only downside is the fact that you have to invest some time to maintain and prepare the data for each sprint, but for us that was hugely outweighed by the flexibility and accessibility that the Team of GoogleDocs + VoIP gave us.

Lambda Expression Java 8

In Java 1.8 (Java 8) this has become lot easier by using forEach method from Aggregate operations(Stream operations) that looks similar to iterators from Iterable Interface.

Just copy paste below statement to your code and rename the HashMap variable from hm to your HashMap variable to print out key-value pair.

HashMap<Integer,Integer> hm = new HashMap<Integer, Integer>();
/*
 *     Logic to put the Key,Value pair in your HashMap hm
 */

// Print the key value pair in one line.
hm.forEach((k,v) -> System.out.println("key: "+k+" value:"+v));

Here is an example where a Lambda Expression is used:

    HashMap<Integer,Integer> hm = new HashMap<Integer, Integer>();
    Random rand = new Random(47);
    int i=0;
    while(i<5){
        i++;
        int key = rand.nextInt(20);
        int value = rand.nextInt(50);
        System.out.println("Inserting key: "+key+" Value: "+value);
        Integer imap =hm.put(key,value);
        if( imap == null){
            System.out.println("Inserted");
        }
        else{
            System.out.println("Replaced with "+imap);
        }               
    }

    hm.forEach((k,v) -> System.out.println("key: "+k+" value:"+v));

Output:

Inserting key: 18 Value: 5
Inserted
Inserting key: 13 Value: 11
Inserted
Inserting key: 1 Value: 29
Inserted
Inserting key: 8 Value: 0
Inserted
Inserting key: 2 Value: 7
Inserted
key: 1 value:29
key: 18 value:5
key: 2 value:7
key: 8 value:0
key: 13 value:11

Also one can use Spliterator for the same.

Spliterator sit = hm.entrySet().spliterator();

UPDATE

Including documentation links to Oracle Docs. For more on Lambda go to this link and must read Aggregate Operations and for Spliterator go to this link.

.each() should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map.

var newArray = $(array).map(function(i) {
    return $('#event' + i, response).html();
});

Edit: I removed the adding of the prepended 0 since it is suggested to not use that.

If you must have it use

var newArray = $(array).map(function(i) {
    var number = '' + i;
    if (number.length == 1) {
        number = '0' + number;
    }   
    return $('#event' + number, response).html();
});
