You can also extract the event code from the HTML, like this :

<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>

<script>
function selectAll(frmElement, chkElement) {
    // ...
}
document.getElementById("check_all_1").onclick = function() {
    selectAll(document.wizard_form, this);
}
</script>

In the specific case above, you could do parent/child juggling.

$(this).parents("tr").children("td:first").text()

This works:

SELECT STR_TO_DATE(dateColumn, '%c/%e/%Y %r') FROM tabbleName WHERE 1

I was also stuck on this problem then I saw that the ids of the modal are the same. You need different ids of modals if you want multiple modals. I used dynamic id. Here is my code in haml:

.modal.hide.fade{"id"=> discount.id,"aria-hidden" => "true", "aria-labelledby" => "myModalLabel", :role => "dialog", :tabindex => "-1"}

you can do this

<div id="<%= some.id %>" class="modal hide fade in">
  <div class="modal-header">
    <a class="close" data-dismiss="modal">×</a>
    <h3>Header</h3>
  </div>
  <div class="modal-body"></div>
  <div class="modal-footer">
    <input type="submit" class="btn btn-success" value="Save" />
  </div>
</div>

and your links to modal will be

<a data-toggle="modal" data-target="#" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>

I hope this will work for you.

I use this at work :) IE6+ https://gist.github.com/GrzegorzPerko/7183390

Don't forget about <element class="ahover"><span>Text</span></a> if you use a text element.

.ahover {
    display: block;
    /** text-indent: -999em; ** if u use only only img **/
    position: relative;
}
.ahover:after {
    content: "";
    height: 100%;
    left: 0;
    opacity: 0;
    position: absolute;
    top: 0;
    transition: all 0.5s ease 0s;
    width: 100%;
    z-index: 1;
}
.ahover:hover:after {
    opacity: 1;
}
.ahover span {
    display: block;
    position: relative;
    z-index: 2;
}

The official tutorial discusses deploying an app to production. One option is to use Waitress, a production WSGI server. Other servers include Gunicorn and uWSGI.

When running publicly rather than in development, you should not use the built-in development server (flask run). The development server is provided by Werkzeug for convenience, but is not designed to be particularly efficient, stable, or secure.

Instead, use a production WSGI server. For example, to use Waitress, first install it in the virtual environment:

$ pip install waitress

You need to tell Waitress about your application, but it doesn’t use FLASK_APP like flask run does. You need to tell it to import and call the application factory to get an application object.

$ waitress-serve --call 'flaskr:create_app'
Serving on http://0.0.0.0:8080

Or you can use waitress.serve() in the code instead of using the CLI command.

from flask import Flask

app = Flask(__name__)

@app.route("/")
def index():
    return "<h1>Hello!</h1>"

if __name__ == "__main__":
    from waitress import serve
    serve(app, host="0.0.0.0", port=8080)

$ python hello.py

If one just want to schedule a countdown until a time in the future with regular notifications on intervals along the way, you can use the CountDownTimer class that is available since API level 1.

new CountDownTimer(30000, 1000) {
    public void onTick(long millisUntilFinished) {
        editText.setText("Seconds remaining: " + millisUntilFinished / 1000);
    }

    public void onFinish() {
        editText.setText("Done");
    }
}.start();

If you want to overwrite the element with key 0

function[0] = 42;

Otherwise:

function.insert(std::make_pair(0, 42));

For the question

How can i run a jar file in command prompt but with arguments

.

To pass arguments to the jar file at the time of execution

java -jar myjar.jar arg1 arg2

In the main() method of "Main-Class" [mentioned in the manifest.mft file]of your JAR file. you can retrieve them like this:

String arg1 = args[0];
String arg2 = args[1];

Your variable is set correctly by testvar=$(cat test.txt). To display this variable which consist new line characters, simply add double quotes, e.g.

echo "$testvar" 

Here is the full example:

$ printf "test1\ntest2" > test.txt
$ testvar=$(<test.txt)
$ grep testvar <(set)
testvar=$'test1\ntest2'
$ echo "$testvar"
text1
text2
$ printf "%b" "$testvar"
text1
text2

How about

try
{
    WebId = Guid.Empty;
    WebId = new Guid(queryString["web"]);
}
catch (FormatException)
{
}
catch (OverflowException)
{
}

Try this

i was facing lot of issues when i was trying other solution...... After lot of R&D now i got solution

1. create custom_spinner.xml in layout folder and paste this code

    <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="vertical"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:background="@color/colorGray">
   <TextView
   android:id="@+id/tv_spinnervalue"
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:textColor="@color/colorWhite"
   android:gravity="center"
   android:layout_alignParentLeft="true"
   android:textSize="@dimen/_18dp"
   android:layout_marginTop="@dimen/_3dp"/>
   <ImageView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:layout_alignParentRight="true"
   android:background="@drawable/men_icon"/>
   </RelativeLayout>
   

2. in your activity

   Spinner spinner =(Spinner)view.findViewById(R.id.sp_colorpalates);
   String[] years = {"1996","1997","1998","1998"};
   spinner.setAdapter(new SpinnerAdapter(this, R.layout.custom_spinner, years));
   

3. create a new class of adapter

   public class SpinnerAdapter extends ArrayAdapter<String> {
   private String[] objects;
   
   public SpinnerAdapter(Context context, int textViewResourceId, String[] objects) {
       super(context, textViewResourceId, objects);
       this.objects=objects;
   }
   
   @Override
   public View getDropDownView(int position, View convertView, @NonNull ViewGroup parent) {
       return getCustomView(position, convertView, parent);
   }
   
   @NonNull
   @Override
   public View getView(int position, View convertView, @NonNull ViewGroup parent) {
       return getCustomView(position, convertView, parent);
   }
   
   private View getCustomView(final int position, View convertView, ViewGroup parent) {
       View row = LayoutInflater.from(parent.getContext()).inflate(R.layout.custom_spinner, parent, false);
       final TextView label=(TextView)row.findViewById(R.id.tv_spinnervalue);
       label.setText(objects[position]);
       return row;
   }
   }
   

Referenced file contains errors (http://www.springframework.org/schema/context/spring-context-3.0.xsd)

i faced this problem, when i was configuring dispatcher-servlet.xml ,you can remove this:

xsi:schemaLocation="http://www.springframework.org/schema/beans
  http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
  http://www.springframework.org/schema/context
  http://www.springframework.org/schema/context/spring-context-3.0.xsd"

from your xml and you can also follow the steps go to window -> preferences -> validation -> and unchecked XML validator and XML schema validator.

I had the same error when I imported web requests from fiddler captured sessions to Visual Studio webtests. Some POST requests did not have a StringHttpBody tag. I added an empty one to them and the error was gone. Add this after the Headers tag:

    <StringHttpBody ContentType="" InsertByteOrderMark="False">
  </StringHttpBody>

The jQuery way

In jQuery, you can use $('#id').children().length > 0 to test if an element has children.

Demo

var test1 = $('#test');_x000D_
var test2 = $('#test2');_x000D_
_x000D_
if(test1.children().length > 0) {_x000D_
    test1.addClass('success');_x000D_
} else {_x000D_
    test1.addClass('failure');_x000D_
}_x000D_
_x000D_
if(test2.children().length > 0) {_x000D_
    test2.addClass('success');_x000D_
} else {_x000D_
    test2.addClass('failure');_x000D_
}

.success {_x000D_
    background: #9f9;_x000D_
}_x000D_
_x000D_
.failure {_x000D_
    background: #f99;_x000D_
}

<script src="https://code.jquery.com/jquery-1.12.2.min.js"></script>_x000D_
<div id="test">_x000D_
   <span>Children</span>_x000D_
</div>_x000D_
<div id="test2">_x000D_
   No children_x000D_
</div>

The vanilla JS way

If you don't want to use jQuery, you can use document.getElementById('id').children.length > 0 to test if an element has children.

Demo

var test1 = document.getElementById('test');_x000D_
var test2 = document.getElementById('test2');_x000D_
_x000D_
if(test1.children.length > 0) {_x000D_
    test1.classList.add('success');_x000D_
} else {_x000D_
    test1.classList.add('failure');_x000D_
}_x000D_
_x000D_
if(test2.children.length > 0) {_x000D_
    test2.classList.add('success');_x000D_
} else {_x000D_
    test2.classList.add('failure');_x000D_
}

.success {_x000D_
    background: #9f9;_x000D_
}_x000D_
_x000D_
.failure {_x000D_
    background: #f99;_x000D_
}

<div id="test">_x000D_
   <span>Children</span>_x000D_
</div>_x000D_
<div id="test2">_x000D_
   No children_x000D_
</div>

Run project as Maven test, then Run as JUnit Test.

A lot of focus in the suggestions above on inventing ways in runtime to pass in variables, set them and clear them and so on..? But to test things 'structurally', I guess you want to have different test suites for different scenarios? Pretty much like when you want to run your 'heavier' integration test builds, whereas in most cases you just want to skip them. But then you don't try and 'invent ways to set stuff in runtime', rather you just tell maven what you want? It used to be a lot of work telling maven to run specific tests via profiles and such, if you google around people would suggest doing it via springboot (but if you haven't dragged in the springboot monstrum into your project, it seems a horrendous footprint for 'just running JUnits', right?). Or else it would imply loads of more or less inconvenient POM XML juggling which is also tiresome and, let's just say it, 'a nineties move', as inconvenient as still insisting on making 'spring beans out of XML', showing off your ultimate 600 line logback.xml or whatnot...?

Nowadays, you can just use Junit 5 (this example is for maven, more details can be found here JUnit 5 User Guide 5)

 <dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.junit</groupId>
            <artifactId>junit-bom</artifactId>
            <version>5.7.0</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

and then

    <dependency>
        <groupId>org.junit.jupiter</groupId>
        <artifactId>junit-jupiter</artifactId>
        <scope>test</scope>
    </dependency>

and then in your favourite utility lib create a simple nifty annotation class such as

@Target({ ElementType.TYPE, ElementType.METHOD })
@Retention(RetentionPolicy.RUNTIME)
@EnabledIfEnvironmentVariable(named = "MAVEN_CMD_LINE_ARGS", matches = "(.*)integration-testing(.*)")
public @interface IntegrationTest {}

so then whenever your cmdline options contain -Pintegration-testing for instance, then and only then will your @IntegrationTest annotated test-class/method fire. Or, if you don't want to use (and setup) a specific maven profile but rather just pass in 'trigger' system properties by means of

mvn <cmds> -DmySystemPop=mySystemPropValue

and adjust your annotation interface to trigger on that (yes, there is also a @EnabledIfSystemProperty). Or making sure your shell is set up to contain 'whatever you need' or, as is suggested above, actually going through 'the pain' adding system env via your POM XML.

Having your code internally in runtime fiddle with env or mocking env, setting it up and then possibly 'clearing' runtime env to change itself during execution just seems like a bad, perhaps even dangerous, approach - it's easy to imagine someone will always sooner or later make a 'hidden' internal mistake that will go unnoticed for a while, just to arise suddenly and bite you hard in production later..? You usually prefer an approach entailing that 'given input' gives 'expected output', something that is easy to grasp and maintain over time, your fellow coders will just see it 'immediately'.

Well long 'answer' or maybe rather just an opinion on why you'd prefer this approach (yes, at first I just read the heading for this question and went ahead to answer that, ie 'How to test code dependent on environment variables using JUnit').

I've succeded doing this with InnoSetup.

I checked the existence of registry key:

HKLM\SOFTWARE\Microsoft\VisualStudio\11.0\VC\Runtimes

If uninstalled, it does not exist. If installed, it exists.

By the way, it could also be in the Wow6432Node:

HKLM\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\11.0\VC\Runtimes

maybe this can help..

SELECT constraint_name, constraint_type, column_name
from user_constraints natural join user_cons_columns
where table_name = "my_table_name";

Two different options to add item to an array without mutation

case ADD_ITEM :
    return { 
        ...state,
        arr: [...state.arr, action.newItem]
    }

OR

case ADD_ITEM :
    return { 
        ...state,
        arr: state.arr.concat(action.newItem)
    }

Unbelievable, but on httpd 2.2 on centos 6.4 this works.

Export env vars in /etc/sysconfig/httpd

export mydocroot=/var/www/html

Then simply do this...

<VirtualHost *:80>
  DocumentRoot ${mydocroot}
</VirtualHost>

Then finally....

service httpd restart;

Collection is the main interface of Java Collections hierarchy and List(Sequence) is one of the sub interfaces that defines an ordered collection.

Use parseInt().

var num = 2.9
console.log(parseInt(num, 10)); // 2

You can also use |.

var num = 2.9
console.log(num | 0); // 2

I'm coming from a SQL Server background also and spent the past 2 weeks figuring out how to run scripts like this in IBM Data Studio. Hope it helps.

CREATE VARIABLE v_lookupid INTEGER DEFAULT (4815162342); --where 4815162342 is your variable data 
  SELECT * FROM DB1.PERSON WHERE PERSON_ID = v_lookupid;
  SELECT * FROM DB1.PERSON_DATA WHERE PERSON_ID = v_lookupid;
  SELECT * FROM DB1.PERSON_HIST WHERE PERSON_ID = v_lookupid;
DROP VARIABLE v_lookupid; 

Use insert method from range, for example

Sub InsertColumn()
        Columns("C:C").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
        Range("C1").Value = "Loc"
End Sub

If I've understood your question correctly, then you are looking for the mouseup event, rather than the click event:

$("#message_link").mouseup(function() {
    //Do stuff here
});

The mouseup event fires when the mouse button is released, and does not take into account whether the mouse button was pressed on that element, whereas click takes into account both mousedown and mouseup.

However, click should work fine, because it won't actually fire until the mouse button is released.

You can use the HTML tag in order to apply font size, font color in one line on JavaScript, as well as you can use .fontcolor() method to define color, .fontsize() method to define the font size, .bold() method to define bold, etc. These are called JavaScript Built-in Functions.

• Here is a list of some JavaScript built-in functions:

  .big()
  .small()
  .italics()
  .fixed()
  .strike()
  .sup()

• The below built-in functions require parameters:

  .fontsize() //e.g.: the size to be applied in number .fontsize(4)

  .fontcolor("") //e.g.: the color to be applied in string .fontcolor("red")

  .txt.link("") //e.g.: the url to be linkable as string .link("www.test.com")

  .toUpperCase() //e.g.: the converted to uppercase to be applied in string .toUpperCase()

• Remember the syntax is: string.functionName() e.g.:

  var txt = "Hello World!"; txt.bold();

• This also can be done in one line:

  var txt = "Hello World!".bold();

  The result will be: Hello World!

• You can use multiple built-in functions in one line, adding one next to the other. e.g.:

  "10/22/2018".fontcolor("red").fontsize(4).bold()

• The following is an example how I used it on my JavaScript code to change font (color, size, bold) using both HTML tags and JavaScript functions:

vForm.message = "<HTML><font size = 4 color = 'red'><b> Application Deadline was </b></font></HTML> " + "10/22/2018".fontcolor("red").fontsize(4).bold(); /* setting HTML font color, size, bold and combined them with JavaScript functions to change font color, size, bold in JavaScript code */

• Here is the result:

You can create tags for GitHub by either using:

• the Git command line, or
• GitHub's web interface.

Creating tags from the command line

To create a tag on your current branch, run this:

git tag <tagname>

If you want to include a description with your tag, add -a to create an annotated tag:

git tag <tagname> -a

This will create a local tag with the current state of the branch you are on. When pushing to your remote repo, tags are NOT included by default. You will need to explicitly say that you want to push your tags to your remote repo:

git push origin --tags

From the official Linux Kernel Git documentation for git push:

--tags

All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line.

Or if you just want to push a single tag:

git push origin <tag>

See also my answer to How do you push a tag to a remote repository using Git? for more details about that syntax above.

Creating tags through GitHub's web interface

You can find GitHub's instructions for this at their Creating Releases help page. Here is a summary:

1. Click the releases link on our repository page,

   

2. Click on Create a new release or Draft a new release,

   

3. Fill out the form fields, then click Publish release at the bottom,

   

4. After you create your tag on GitHub, you might want to fetch it into your local repository too:

   git fetch
   

Now next time, you may want to create one more tag within the same release from website. For that follow these steps:

Go to release tab

1. Click on edit button for the release

2. Provide name of the new tag ABC_DEF_V_5_3_T_2 and hit tab

3. After hitting tab, UI will show this message: Excellent! This tag will be created from the target when you publish this release. Also UI will provide an option to select the branch/commit

4. Select branch or commit

5. Check "This is a pre-release" checkbox for qa tag and uncheck it if the tag is created for Prod tag.

6. After that click on "Update Release"

7. This will create a new Tag within the existing Release.

Static variable in a header file:

say 'common.h' has

static int zzz;

This variable 'zzz' has internal linkage (This same variable can not be accessed in other translation units). Each translation unit which includes 'common.h' has it's own unique object of name 'zzz'.

Static variable in a class:

Static variable in a class is not a part of the subobject of the class. There is only one copy of a static data member shared by all the objects of the class.

$9.4.2/6 - "Static data members of a class in namespace scope have external linkage (3.5).A local class shall not have static data members."

So let's say 'myclass.h' has

struct myclass{
   static int zzz;        // this is only a declaration
};

and myclass.cpp has

#include "myclass.h"

int myclass::zzz = 0           // this is a definition, 
                               // should be done once and only once

and "hisclass.cpp" has

#include "myclass.h"

void f(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

and "ourclass.cpp" has

#include "myclass.h"
void g(){myclass::zzz = 2;}    // myclass::zzz is always the same in any 
                               // translation unit

So, class static members are not limited to only 2 translation units. They need to be defined only once in any one of the translation units.

Note: usage of 'static' to declare file scope variable is deprecated and unnamed namespace is a superior alternate

Time flies!

On version 12, I have to use "password" instead of "ident" here:

local   all             postgres                                password

Connect without using the -h option.

Try it:

document.querySelector("input").addEventListener("keyup", function () {
   this.value = this.value.replace(/\D/, "")
});

// Embarcadero C++ Builder 

// convertion string to wstring
string str1 = "hello";
String str2 = str1;         // typedef UnicodeString String;   -> str2 contains now u"hello";

// convertion wstring to string
String str2 = u"hello";
string str1 = UTF8string(str2).c_str();   // -> str1 contains now "hello"

just modify dave1010's code for my need

 (function($){
    $.fn.extend({hideOptions: function() {
        var s = this;
        return s.each(function(i,e) {
            var d = $.data(e, 'disabledOptions') || [];
            $(e).find("option[disabled=\"disabled\"]").each(function() {
                d.push($(this).detach());
            });

        });
    }, showOptions: function() {

            var d = $.data(e, 'disabledOptions') || [];
            for (var i in d) {
                $(e).append(d[i]);
            }
        });
    }});

This seems to work okay for me. yourDateTime.ToString().Substring(2);

The globals() function returns a dictionary containing all your global variables.

>>> apple = 1
>>> banana = 'f'
>>> carrot = 3
>>> globals()
{'carrot': 3, 'apple': 1, '__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__doc__': None, 'banana': 'f'}

There is also a similar function called locals().

I realise this is probably not exactly what you want, but it may provide some insight into how Python provides access to your variables.

Edit: It sounds like your problem may be better solved by simply using a dictionary in the first place:

fruitdict = {}
fruitdict['apple'] = 1
fruitdict['banana'] = 'f'
fruitdict['carrot'] = 3

For documentation purpose, it's better to list the string values that are legal:

size: PropTypes.oneOfType([
    PropTypes.number,
    PropTypes.oneOf([ 'SMALL', 'LARGE' ]),
]),

According to the documentation, it's

CREATE TABLE something (
  column1, 
  column2, 
  column3, 
  PRIMARY KEY (column1, column2)
);

Servers sometimes compress their responses to save on bandwidth, when this happens, you need to decompress the response before attempting to read it. Fortunately, the .NET framework can do this automatically, however, we have to turn the setting on.

Here's an example of how you could achieve that.

string html = string.Empty;
string url = @"https://api.stackexchange.com/2.2/answers?order=desc&sort=activity&site=stackoverflow";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
request.AutomaticDecompression = DecompressionMethods.GZip;

using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
using (Stream stream = response.GetResponseStream())
using (StreamReader reader = new StreamReader(stream))
{
    html = reader.ReadToEnd();
}

Console.WriteLine(html);

GET

public string Get(string uri)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

    using(HttpWebResponse response = (HttpWebResponse)request.GetResponse())
    using(Stream stream = response.GetResponseStream())
    using(StreamReader reader = new StreamReader(stream))
    {
        return reader.ReadToEnd();
    }
}

GET async

public async Task<string> GetAsync(string uri)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    request.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;

    using(HttpWebResponse response = (HttpWebResponse)await request.GetResponseAsync())
    using(Stream stream = response.GetResponseStream())
    using(StreamReader reader = new StreamReader(stream))
    {

If the image size is variable or the design is responsive, in addition to wrapping the text, you can set a min width for the paragraph to avoid it to become too narrow.
Give an invisible CSS pseudo-element with the desired minimum paragraph width. If there isn't enough space to fit this pseudo-element, then it will be pushed down underneath the image, taking the paragraph with it.

#container:before {
  content: ' ';
  display: table;
  width: 10em;    /* Min width required */
}
#floated{
    float: left;
    width: 150px;
    background: red;
}

If you are still trying to put files relative to your executable instead of in the temp directory, you need to copy it yourself. This is how I ended up getting it done.

https://stackoverflow.com/a/59415662/999943

You add a step in the spec file that does a filesystem copy to the DISTPATH variable.

Hope that helps.

Since JDBC doesn't support this option the best way to solve this question is executing command lines via the Java Program. Bellow is an example to postgresql:

private void executeSqlFile() {
     try {
         Runtime rt = Runtime.getRuntime();
         String executeSqlCommand = "psql -U (user) -h (domain) -f (script_name) (dbName)";
         Process pr = rt.exec();
         int exitVal = pr.waitFor();
         System.out.println("Exited with error code " + exitVal);
      } catch (Exception e) {
        System.out.println(e.toString());
      }
}

I believe .clone() is what you're looking for, so long as the class supports it.

I found a plugin that helped me do this within seconds without editing code:

https://wordpress.org/plugins/quick-pagepost-redirect-plugin/

I found it here: http://premium.wpmudev.org/blog/wordpress-link-title-external-url/

From Typescript 3.7 on, you can also use nullish coalescing:

let x = foo ?? bar();

Which is the equivalent for checking for null or undefined:

let x = (foo !== null && foo !== undefined) ?
    foo :
    bar();

https://www.typescriptlang.org/docs/handbook/release-notes/typescript-3-7.html#nullish-coalescing

While not exactly the same, you could write your code as:

var uemail = localStorage.getItem("useremail") ?? alert('Undefined');

Don't use int. Files over 2 gigabytes in size are common as dirt these days

Don't use unsigned int. Files over 4 gigabytes in size are common as some slightly-less-common dirt

IIRC the standard library defines off_t as an unsigned 64 bit integer, which is what everyone should be using. We can redefine that to be 128 bits in a few years when we start having 16 exabyte files hanging around.

If you're on windows, you should use GetFileSizeEx - it actually uses a signed 64 bit integer, so they'll start hitting problems with 8 exabyte files. Foolish Microsoft! :-)

One easy way I found was the following: Implement this is your dialogFragment,

  CallingActivity callingActivity = (CallingActivity) getActivity();
  callingActivity.onUserSelectValue("insert selected value here");
  dismiss();

And then in the activity that called the Dialog Fragment create the appropriate function as such:

 public void onUserSelectValue(String selectedValue) {

        // TODO add your implementation.
      Toast.makeText(getBaseContext(), ""+ selectedValue, Toast.LENGTH_LONG).show();
    }

The Toast is to show that it works. Worked for me.

Yes, you need to have the header Access-Control-Allow-Origin: http://domain.com:3000 or Access-Control-Allow-Origin: * on both the OPTIONS response and the POST response. You should include the header Access-Control-Allow-Credentials: true on the POST response as well.

Your OPTIONS response should also include the header Access-Control-Allow-Headers: origin, content-type, accept to match the requested header.

The solution would be to use sessionStorage, FYI: https://developer.mozilla.org/en-US/docs/Web/API/Window/sessionStorage

I would say that one should omit the __init__.py only if one wants to have the implicit namespace package. If you don't know what it means, you probably don't want it and therefore you should continue to use the __init__.py even in Python 3.

This example will help you:

<form>
    <input type="button" value="Open Window" onclick="window.open('http://www.google.com')">
</form>

You can open next page on same page by:

<input type="button" value="Open Window" onclick="window.open('http://www.google.com','_self')">

I see a couple of issues.

First:

ser.read() is only going to return 1 byte at a time.

If you specify a count

ser.read(5)

it will read 5 bytes (less if timeout occurrs before 5 bytes arrive.)

If you know that your input is always properly terminated with EOL characters, better way is to use

ser.readline()

That will continue to read characters until an EOL is received.

Second:

Even if you get ser.read() or ser.readline() to return multiple bytes, since you are iterating over the return value, you will still be handling it one byte at a time.

Get rid of the

for line in ser.read():

and just say:

line = ser.readline()

Sounds like you need to add the formatting to the WHERE:

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d') 
FROM users 
WHERE DATE_FORMAT(users.signup_date, '%Y-%m-%d') = CURDATE()

See SQL Fiddle with Demo

It could be not supported file encoding. Change it to UTF-8 for example.

I've done this using Sublime

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

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

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

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

For further details, see MDN article and RFC 3986.

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

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

This function can parse even URLs like

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

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

Thought I'd give a full answer combining some of the possible intricacies required for completeness.

1. Check if you have 32-bit or 64-bit IIS installed:
   • Go to IIS Manager ? Application Pools, choose the appropriate app pool then Advanced Settings.
   • Check the setting "Enable 32-bit Applications". If that's true, that means the worker process is forced to run in 32-bit. If the setting is false, then the app pool is running in 64-bit mode.
   • You can also open up Task Manager and check w3wp.exe. If it's showing as w3wp*32.exe then it's 32-bit.
2. Download the appropriate version here: https://www.iis.net/downloads/microsoft/url-rewrite#additionalDownloads.
3. Install it.
4. Close and reopen IIS Manager to ensure the URL Rewrite module appears.

you can create selector file in res/drawable

example: res/drawable/selector_button.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/btn_disabled" android:state_enabled="false" />
    <item android:drawable="@drawable/btn_enabled" />
</selector>

and in layout activity, fragment or etc

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/selector_bg_rectangle_black"/>

I had the same issue. It seems the easiest solution is to just remove the remote, readd it, and fetch.

I would like you to have a look at redux http://redux.js.org/index.html

They have very well defined way of handling async calls ie API calls, and instead of using jQuery for API calls, I would like to recommend using fetch or request npm packages, fetch is currently supported by modern browsers, but a shim is also available for server side.

There is also this another amazing package superagent, which has alot many options when making an API request and its very easy to use.

UPDATE 2019. If you have dedicated server and SSD or better NVM, 3.5GHZ. You shouldn't use buffering to make faster loaded website in 100ms-150ms.

Becouse network is slowly than proccesing script in the 2019 with performance servers (severs,memory,disk) and with turn on APC PHP :) To generated script sometimes need only 70ms another time is only network takes time, from 10ms up to 150ms from located user-server.

so if you want be fast 150ms, buffering make slowl, becouse need extra collection buffer data it make extra cost. 10 years ago when server make 1s script, it was usefull.

Please becareful output_buffering have limit if you would like using jpg to loading it can flush automate and crash sending.

Cheers.

You can make fast river or You can make safely tama :)

If we declare a variable as static, there will be only one copy of the variable. So, whenever different threads access that variable, there will be only one final value for the variable(since there is only one memory location allocated for the variable).

If a variable is declared as volatile, all threads will have their own copy of the variable but the value is taken from the main memory.So, the value of the variable in all the threads will be the same.

So, in both cases, the main point is that the value of the variable is same across all threads.

I did test your code and the only problem I could see was the lack of permission given to the directory you try to write the file in to.

Give "write" permission to the directory you need to put the file. In your case it is the current directory.

Use "chmod" in linux.

Add "Everyone" with "write" enabled to the security tab of the directory if you are in Windows.

The second time you're referring to div2, you're not using the # id selector.

There's no element named div2.

If MouseEvent.offsetX is supported by your browser (all major browsers actually support it), The jQuery Event object will contain this property.

The MouseEvent.offsetX read-only property provides the offset in the X coordinate of the mouse pointer between that event and the padding edge of the target node.

$("#seek-bar").click(function(event) {
  var x = event.offsetX
  alert(x);    
});

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

Data variables ($email, $subject) seems to be global. And globals cannot be read inside functions. You must pass them as parameters (the recommended way) or declare them as global.

Try this way:

Mail::send('emails.activation', $data, function($message, $email, $subject){
        $message->to($email)->subject($subject);
    });
            ->with('title', "Registered Successfully.");

The difference between --save and --save-dev may not be immediately noticeable if you have tried them both on your own projects. So here are a few examples...

Lets say you were building an app that used the moment package to parse and display dates. Your app is a scheduler so it really needs this package to run, as in: cannot run without it. In this case you would use

npm install moment --save

This would create a new value in your package.json

"dependencies": {
   ...
   "moment": "^2.17.1"
}

When you are developing, it really helps to use tools such as test suites and may need jasmine-core and karma. In this case you would use

npm install jasmine-core --save-dev
npm install karma --save-dev

This would also create a new value in your package.json

"devDependencies": {
    ...
    "jasmine-core": "^2.5.2",
    "karma": "^1.4.1",
}

You do not need the test suite to run the app in its normal state, so it is a --save-dev type dependency, nothing more. You can see how if you do not understand what is really happening, it is a bit hard to imagine.

Taken directly from NPM docs docs#dependencies

Dependencies

Dependencies are specified in a simple object that maps a package name to a version range. The version range is a string which has one or more space-separated descriptors. Dependencies can also be identified with a tarball or git URL.

Please do not put test harnesses or transpilers in your dependencies object. See devDependencies, below.

Even in the docs, it asks you to use --save-dev for modules such as test harnesses.

I hope this helps and is clear.

I would strongly recommend using a library like PHPMailer to send emails.
It's easier and handles most of the issues automatically for you.

Regarding displaying embedded (inline) images, here's what's on their documentation:

Inline Attachments

There is an additional way to add an attachment. If you want to make a HTML e-mail with images incorporated into the desk, it's necessary to attach the image and then link the tag to it. For example, if you add an image as inline attachment with the CID my-photo, you would access it within the HTML e-mail with <img src="cid:my-photo" alt="my-photo" />.

In detail, here is the function to add an inline attachment:

$mail->AddEmbeddedImage(filename, cid, name);
//By using this function with this example's value above, results in this code:
$mail->AddEmbeddedImage('my-photo.jpg', 'my-photo', 'my-photo.jpg ');

To give you a more complete example of how it would work:

<?php
require_once('../class.phpmailer.php');
$mail = new PHPMailer(true); // the true param means it will throw exceptions on     errors, which we need to catch

$mail->IsSMTP(); // telling the class to use SMTP

try {
  $mail->Host       = "mail.yourdomain.com"; // SMTP server
  $mail->Port       = 25;                    // set the SMTP port
  $mail->SetFrom('[email protected]', 'First Last');
  $mail->AddAddress('[email protected]', 'John Doe');
  $mail->Subject = 'PHPMailer Test';

  $mail->AddEmbeddedImage("rocks.png", "my-attach", "rocks.png");
  $mail->Body = 'Your <b>HTML</b> with an embedded Image: <img src="cid:my-attach"> Here is an image!';

  $mail->AddAttachment('something.zip'); // this is a regular attachment (Not inline)
  $mail->Send();
  echo "Message Sent OK<p></p>\n";
} catch (phpmailerException $e) {
  echo $e->errorMessage(); //Pretty error messages from PHPMailer
} catch (Exception $e) {
  echo $e->getMessage(); //Boring error messages from anything else!
}
?>

Edit:

Regarding your comment, you asked how to send HTML email with embedded images, so I gave you an example of how to do that.
The library I told you about can send emails using a lot of methods other than SMTP.
Take a look at the PHPMailer Example page for other examples.

One way or the other, if you don't want to send the email in the ways supported by the library, you can (should) still use the library to build the message, then you send it the way you want.

For example:

You can replace the line that send the email:

$mail->Send();

With this:

$mime_message = $mail->CreateBody(); //Retrieve the message content
echo $mime_message; // Echo it to the screen or send it using whatever method you want

Hope that helps. Let me know if you run into trouble using it.

You can change configuration file schema back to DotNetConfig.xsd via properties of the app.config file. To find destination of needed schema, you can search it by name or create a WinForms application, add to project the configuration file and in it's properties, you'll find full path to file.

The answer given by P????? creates a nullable bool, not a bool, which may be fine for you. For example in C# it would create: bool? AdminApprovednot bool AdminApproved.

If you need to create a bool (defaulting to false):

    ALTER TABLE person
    ADD AdminApproved BIT
    DEFAULT 0 NOT NULL;

You can also use references on foreach values:

foreach($array as $elementKey => &$element) {
    // $element is the same than &$array[$elementKey]
    if (isset($element['id']) and $element['id'] == 'searched_value') {
        unset($element);
    }
}

In JavaScript:

document.getElementById("id").style.display = null;

In jQuery:

$("#id").css('display',null);

As of now, you can only store string values in localStorage. You'll need to serialize the array object and then store it in localStorage.

For example:

localStorage.setItem('session', a.join('|'));

or

localStorage.setItem('session', JSON.stringify(a));

I prefer not to use a prefix on interfaces:

• The prefix hurts readability.

• Using interfaces in clients is the standard best way to program, so interfaces names should be as short and pleasant as possible. Implementing classes should be uglier to discourage their use.

• When changing from an abstract class to an interface a coding convention with prefix I implies renaming all the occurrences of the class --- not good!

You have a javascript object

$1 and $2 are jquery objects, maybe use alert($1.text()); to get text or alert($1.attr('id'); etc...

you have to treat $1 and $2 like jQuery objects.

If you have a more complex case than the common case that can not be handled with ``, then check out Kernel.spawn(). This seems to be the most generic/full-featured provided by stock Ruby to execute external commands.

You can use it to:

• create process groups (Windows).
• redirect in, out, error to files/each-other.
• set env vars, umask.
• change the directory before executing a command.
• set resource limits for CPU/data/etc.
• Do everything that can be done with other options in other answers, but with more code.

The Ruby documentation has good enough examples:

env: hash
  name => val : set the environment variable
  name => nil : unset the environment variable
command...:
  commandline                 : command line string which is passed to the standard shell
  cmdname, arg1, ...          : command name and one or more arguments (no shell)
  [cmdname, argv0], arg1, ... : command name, argv[0] and zero or more arguments (no shell)
options: hash
  clearing environment variables:
    :unsetenv_others => true   : clear environment variables except specified by env
    :unsetenv_others => false  : dont clear (default)
  process group:
    :pgroup => true or 0 : make a new process group
    :pgroup => pgid      : join to specified process group
    :pgroup => nil       : dont change the process group (default)
  create new process group: Windows only
    :new_pgroup => true  : the new process is the root process of a new process group
    :new_pgroup => false : dont create a new process group (default)
  resource limit: resourcename is core, cpu, data, etc.  See Process.setrlimit.
    :rlimit_resourcename => limit
    :rlimit_resourcename => [cur_limit, max_limit]

      [FD, FD, ...]   : multiple file descriptor in child process

aaa##HTML I would suggest you wrap them in a div, since you will likely end up floating them in certain contexts.

<div class="input-w">
    <label for="your-input">Your label</label>
    <input type="text" id="your-input" />
</div>

CSS

Then within that div, you can make each piece inline-block so that you can use vertical-align to center them - or set baseline etc. (your labels and input might change sizes in the future...

.input-w label, .input-w input {
    float: none; /* if you had floats before? otherwise inline-block will behave differently */
    display: inline-block;
    vertical-align: middle;    
}

UPDATE: mid 2016 + with mobile-first media queries and flex-box

This is how I do things these days.

HTML

<label class='input-w' for='this-input-name'>
  <span class='label'>Your label</span>
  <input class='input' type='text' id='this-input-name' placeholder='hello'>
</label>

<label class='input-w' for='this-other-input-name'>
  <span class='label'>Your label</span>
  <input class='input' type='text' id='this-other-input-name' placeholder='again'>
</label>

This is another method for working with Responsive sizes. It will keep your text centered and maintain its position within its parent. If you don't want it centered then it's even easier, just work with the absolute parameters. Keep in mind the main container is using display: inline-block. There are many others ways to do this, depending on what you're working on.

Based off of Centering the Unknown

Working codepen example here

HTML

<div class="containerBox">
    <div class="text-box">
        <h4>Your Text is responsive and centered</h4>
    </div>
    <img class="img-responsive" src="http://placehold.it/900x100"/>
</div>

CSS

.containerBox {
    position: relative;
    display: inline-block;
}
.text-box {
    position: absolute;    
    height: 100%;
    text-align: center;    
    width: 100%;
}
.text-box:before {
   content: '';
   display: inline-block;
   height: 100%;
   vertical-align: middle;
}
h4 {
   display: inline-block;
   font-size: 20px; /*or whatever you want*/
   color: #FFF;   
}
img {
  display: block;
  max-width: 100%;
  height: auto;
}

other than using this.form.submit() you also submiting by id or name. example i have form like this : <form action="" name="PostName" id="IdName">

1. By Name : <select onchange="PostName.submit()">

2. By Id : <select onchange="IdName.submit()">

Ctrl+Shift+F will do a format of all the code in the page.

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

Another relevant environment variable is:

%ProgramW6432%

So, on a 64-bit machine running in 32-bit (WOW64) mode:

• echo %programfiles% ==> C:\Program Files (x86)
• echo %programfiles(x86)% ==> C:\Program Files (x86)
• echo %ProgramW6432% ==> C:\Program Files

From Wikipedia:

The %ProgramFiles% variable points to the Program Files directory, which stores all the installed programs of Windows and others. The default on English-language systems is "C:\Program Files". In 64-bit editions of Windows (XP, 2003, Vista), there are also %ProgramFiles(x86)%, which defaults to "C:\Program Files (x86)", and %ProgramW6432%, which defaults to "C:\Program Files". The %ProgramFiles% itself depends on whether the process requesting the environment variable is itself 32-bit or 64-bit (this is caused by Windows-on-Windows 64-bit redirection).

Reference: http://en.wikipedia.org/wiki/Environment_variable

 $server_name = "your server name";
 $database_name = "your database name";

}

It's the new feature in C# 6 called Interpolated Strings.

The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.

For more details about this, please take a look at MSDN.

Now, think a little bit more about it. Why this feature is great?

For example, you have class Point:

public class Point
{
    public int X { get; set; }

    public int Y { get; set; }
}

Create 2 instances:

var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };

Now, you want to output it to the screen. The 2 ways that you usually use:

Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");

As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format() to make it nicer:

Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));

This creates a new problem:

1. You have to maintain the number of arguments and index yourself. If the number of arguments and index are not the same, it will generate a runtime error.

For those reasons, we should use new feature:

Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");

The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

For the full post, please read this blog.

This will return what you asked, but I wouldnt recommend using css like this. Use external CSS instead of inline css.

$("tr[id='pDetails']").attr("style").split(':')[1];

In Swift 3 again...

myLabel.font = myLabel.font.withSize(18)

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

Try this:

// this will fix old browsers
if (!Array.prototype.indexOf) {
  Array.prototype.indexOf = function(value) {
    for (var i = 0; i < this.length; i++) {
      if (this[i] === value) {
        return i;
      }
    }

    return -1;
  }
}

// example
if ([1, 2, 3].indexOf(2) != -1) {
  // yay!
}

Shell variables have no type, so the simplest way is to use the return type test command:

if [ $var -eq $var 2> /dev/null ]; then ...

(Or else parse it with a regexp)

This kind of error can also happen when using COPY and having an escaped string containing NULL values(00) such as:

"H\x00\x00\x00tj\xA8\x9E#D\x98+\xCA\xF0\xA7\xBBl\xC5\x19\xD7\x8D\xB6\x18\xEDJ\x1En"

If you use COPY without specifying the format 'CSV' postgres by default will assume format 'text'. This has a different interaction with backlashes, see text format.

If you're using COPY or a file_fdw make sure to specify format 'CSV' to avoid this kind of errors.

@Sventeck, perfecto.

redhat docs are always a great source - good tutorial that explains how to install JDK via yum and then setting the path can be found here (have fun!) - Install OpenJDK and set $JAVA_HOME path

OpenJDK 6:

yum install java-1.6.0-openjdk-devel

OpenJDK 7:

yum install java-1.7.0-openjdk-devel

To list all available java openjdk-devel packages try:

yum list "java-*-openjdk-devel"

Are you talking about automated unit/integration tests or manual tests?

For the former, my rule of thumb (based on measurements) is 40-50% added to development time i.e. if developing a use case takes 10 days (before an QA and serious bugfixing happens), writing good tests takes another 4 to 5 days - though this should best happen before and during development, not afterwards.

I have 4 ships to set on one single map, so I use the Google Developers example and then twisted it

https://developers.google.com/maps/documentation/javascript/examples/icon-complex

In the function bellow I set 3 more color options:

function setMarkers(map, locations) {
...
var image = {
    url: 'img/bullet_amarelo.png',
    // This marker is 20 pixels wide by 32 pixels tall.
    size: new google.maps.Size(40, 40),
    // The origin for this image is 0,0.
    origin: new google.maps.Point(0,0),
    // The anchor for this image is the base of the flagpole at 0,32.
    anchor: new google.maps.Point(0, 40)
  };
  var image1 = {
            url: 'img/bullet_azul.png',
            // This marker is 20 pixels wide by 32 pixels tall.
            size: new google.maps.Size(40, 40),
            // The origin for this image is 0,0.
            origin: new google.maps.Point(0,0),
            // The anchor for this image is the base of the flagpole at 0,32.
            anchor: new google.maps.Point(0, 40)
          };
  var image2 = {
          url: 'img/bullet_vermelho.png',
          // This marker is 20 pixels wide by 32 pixels tall.
          size: new google.maps.Size(40, 40),
          // The origin for this image is 0,0.
          origin: new google.maps.Point(0,0),
          // The anchor for this image is the base of the flagpole at 0,32.
          anchor: new google.maps.Point(0, 40)
        };
  var image3 = {
          url: 'img/bullet_verde.png',
          // This marker is 20 pixels wide by 32 pixels tall.
          size: new google.maps.Size(40, 40),
          // The origin for this image is 0,0.
          origin: new google.maps.Point(0,0),
          // The anchor for this image is the base of the flagpole at 0,32.
          anchor: new google.maps.Point(0, 40)
        };
...
}

And in the FOR bellow I set one color for each ship:

for (var i = 0; i < locations.length; i++) {
...
    if (i==0) var imageV=image;
    if (i==1) var imageV=image1;
    if (i==2) var imageV=image2;
    if (i==3) var imageV=image3;
...
# remember to change icon: image to icon: imageV
}

The final result:

Try to delete the temp files

cd /tmp/
rm -r *

TRUNCATE will blank your table and reset primary key DELETE will also make your table blank but it will not reset primary key.

we can use for truncate

TRUNCATE TABLE tablename

we can use for delete

DELETE FROM tablename

we can also give conditions as below

DELETE FROM tablename WHERE id='xyz'

If you want to delete the cookie completely from all your current domain then the following code will definitely help you.

unset($_COOKIE['hello']);
setcookie("hello", "", time() - 300,"/");

This code will delete the cookie variable completely from all your domain i.e; " / " - it denotes that cookie variable's value all set for all domain not just for current domain or path. time() - 300 denotes that it sets to a previous time so it will expire.

Thats how it's perfectly deleted.

Comparing non-primitives (aka Objects) in Java with == compares their reference instead of their values. Long is a class and thus Long values are Objects.

The problem is that the Java Developers wanted people to use Long like they used long to provide compatibility, which led to the concept of autoboxing, which is essentially the feature, that long-values will be changed to Long-Objects and vice versa as needed. The behaviour of autoboxing is not exactly predictable all the time though, as it is not completely specified.

So to be safe and to have predictable results always use .equals() to compare objects and do not rely on autoboxing in this case:

Long num1 = 127, num2 = 127;
if(num1.equals(num2)) { iWillBeExecutedAlways(); }

You can use a better approach for someone writing HTML for an already existing scss.
html

[attr.role]="<boolean>"

scss

[role = "true"] { ... }

That way you don't need to <boolean> ? true : null every time.

Just find the error reason in here and fix it.

The problem is that MySQL, for whatever inane reason, doesn't allow you to write queries like this:

UPDATE myTable
SET myTable.A =
(
    SELECT B
    FROM myTable
    INNER JOIN ...
)

That is, if you're doing an UPDATE/INSERT/DELETE on a table, you can't reference that table in an inner query (you can however reference a field from that outer table...)

The solution is to replace the instance of myTable in the sub-query with (SELECT * FROM myTable), like this

UPDATE myTable
SET myTable.A =
(
    SELECT B
    FROM (SELECT * FROM myTable) AS something
    INNER JOIN ...
)

This apparently causes the necessary fields to be implicitly copied into a temporary table, so it's allowed.

I found this solution here. A note from that article:

You don’t want to just SELECT * FROM table in the subquery in real life; I just wanted to keep the examples simple. In reality, you should only be selecting the columns you need in that innermost query, and adding a good WHERE clause to limit the results, too.

Learn to use a javascript debugger. Venkman (for Firefox) or the Web Inspector (part of Chome & Safari) are excellent tools for debugging what's going on.

You can set breakpoints and interrogate the state of the machine as you're interacting with your script; step through parts of your code to make sure everything is working as planned, etc.

Here is an excellent write up from WebMonkey on JavaScript Debugging for Beginners. It's a great place to start.

This is my solution to create a fullscreen div, using pure css. It displays a full screen div that is persistent on scrolling. And if the page content fits on the screen, the page won't show a scroll-bar.

my develop environment is

• Xcode 7.0
• 7A220 Swift 2.0
• iOS 9.0

above answers not fully work for me

after try, my finally working solution is:

let indent_large_enought_to_hidden:CGFloat = 10000
cell.separatorInset = UIEdgeInsetsMake(0, indent_large_enought_to_hidden, 0, 0) // indent large engough for separator(including cell' content) to hidden separator
cell.indentationWidth = indent_large_enought_to_hidden * -1 // adjust the cell's content to show normally
cell.indentationLevel = 1 // must add this, otherwise default is 0, now actual indentation = indentationWidth * indentationLevel = 10000 * 1 = -10000

and the effect is:

In Java create the pattern with Pattern p = Pattern.compile("^\\w{14}$"); for further information see the javadoc

Instead of

style="width:100%"

try using

class="col-xs-12"

it will save you 1 character :)

I had some issues that this didn't address in getting this environment set up on OSX. It had to do with the solution that I was maintaining having additional dependencies on some of the Google APIs. It wasn't enough to just download and install the items listed in the first response.

You have to download these.

1. Run Terminal
2. Navigate to the android/sdk directory
3. Type "android" You will get a gui. Check the "Tools" directory and the latest Android API (at this time, it's 4.3 (API 18)).
4. Click "Install xx packages" and go watch an episode of Breaking Bad or something. It'll take a while.
5. Go back to IntelliJ and open the "Project Structure..." dialog (Cmd+;).
6. In the left panel of the dialog, under "Project Settings," select Project. In the right panel, under "Project SDK," click "New..." > Android SDK and navigate to your android/sdk directory. Choose this and you will be presented with a dialog with which you can add the "Google APIs" build target. This is what I needed. You may need to do this more than once if you have multiple version targets.
7. Now, under the left pane "Modules," with your project selected in the center pane, select the appropriate module under the "Dependencies" tab in the right pane.

Another possibility of making.

actionBar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0000ff")));

DateTime.Now.ToString("HH:mm:ss tt");

this gives it to you as a string.

You must declare the reportfile as variable for console.

Problem is all the Dokumentations you can find are not running so .. I was give 1 day of my live to find the right way ....

Example: for batch/console

cmd.exe /K set FFREPORT=file='C:\ffmpeg\proto\test.log':level=32 && C:\ffmpeg\bin\ffmpeg.exe -loglevel warning -report -i inputfile f outputfile

Exemple Javascript:

var reortlogfile = "cmd.exe /K set FFREPORT=file='C:\ffmpeg\proto\" + filename + ".log':level=32 && C:\ffmpeg\bin\ffmpeg.exe" .......;

You can change the dir and filename how ever you want.

It all depends on what is your definition of 'clear'. One of the valid ones certainly is:

slice = slice[:0]

But there's a catch. If slice elements are of type T:

var slice []T

then enforcing len(slice) to be zero, by the above "trick", doesn't make any element of

slice[:cap(slice)]

eligible for garbage collection. This might be the optimal approach in some scenarios. But it might also be a cause of "memory leaks" - memory not used, but potentially reachable (after re-slicing of 'slice') and thus not garbage "collectable".

if (variable) can be used if variable is guaranteed to be an object, or if false, 0, etc. are considered "default" values (hence equivalent to undefined or null).

typeof variable == 'undefined' can be used in cases where a specified null has a distinct meaning to an uninitialised variable or property. This check will not throw and error is variable is not declared.

If you need this code in several places then I'd suggest that you add a short function to keep your code simpler and easier to test.

function add_days( $days, $from_date = null ) {
    if ( is_numeric( $from_date ) ) { 
        $new_date = $from_date; 
    } else { 
        $new_date = time();
    }

    // Timestamp is the number of seconds since an event in the past
    // To increate the value by one day we have to add 86400 seconds to the value
    // 86400 = 24h * 60m * 60s
    $new_date += $days * 86400;

    return $new_date;
}

Then you can use it anywhere like this:

$today       = add_days( 0 );
$tomorrow    = add_days( 1 );
$yesterday   = add_days( -1 );
$in_36_hours = add_days( 1.5 );

$first_reminder  = add_days( 10 );
$second_reminder = add_days( 5, $first_reminder );
$last_reminder   = add_days( 3, $second_reminder );

No, CASE is a function, and can only return a single value. I think you are going to have to duplicate your CASE logic.

The other option would be to wrap the whole query with an IF and have two separate queries to return results. Without seeing the rest of the query, it's hard to say if that would work for you.

adb backup didn't work for me, so here's what I did (Xiaomi Redmi Note 4X, Android 6.0):
1. Go to Settings > Additional Settings > Backup & reset > Local backups.
2. Tap 'Back up' on the bottom of the screen.
3. Uncheck 'System' and 'Apps' checkmarks.
4. Tap detail disclosure button on the right of the 'Apps' cell to navigate to app selection screen.
5. Select the desired app and tap OK.
6. After the backup was completed, the actual file need to be located somehow. Mine could be found at /MIUI/backup/AllBackup/_FOLDER_NAMED_AFTER_BACKUP_CREATION_DATE_.
7. Then I followed the steps from this answer by RonTLV to actually convert the backup file (.bak in my case) to tar (duplicating from the original answer):
"
a) Go here and download: https://sourceforge.net/projects/adbextractor/
b) Extract the downloaded file and navigate to folder where you extracted.
c) run this with your own file names: java -jar abe.jar unpack c:\Intel\xxx.ab c:\Intel\xxx.tar
"

As far as rm -f doing "anything else", it does force (-f is shorthand for --force) silent removal in situations where rm would otherwise ask you for confirmation. For example, when trying to remove a file not writable by you from a directory that is writable by you.

One thing I find that is often missing from these is an ability to look up row locks. At least on the larger databases I have worked on, row locks are not shown in pg_locks (if they were, pg_locks would be much, much larger and there isn't a real data type to show the locked row in that view properly).

I don't know that there is a simple solution to this but usually what I do is look at the table where the lock is waiting and search for rows where the xmax is less than the transaction id present there. That usually gives me a place to start, but it is a bit hands-on and not automation friendly.

Note that shows you uncommitted writes on rows on those tables. Once committed, the rows are not visible in the current snapshot. But for large tables, that is a pain.

(maybe) the easiest way without importing spring-boot.

restTemplate.getInterceptors().add(new BasicAuthorizationInterceptor("user", "password"));

how about using limit 0,1 for mysql optimisation

and about your code:

$DBH = new PDO( "connection string goes here" );

$STH - $DBH -> prepare( "select figure from table1" );

$STH -> execute();

$result = $STH ->fetch(PDO::FETCH_ASSOC)

echo $result["figure"];

$DBH = null;

Radiff2 is a tool designed to compare binary files, similar to how regular diff compares text files.

Try radiff2 which is a part of radare2 disassembler. For instance, with this command:

radiff2 -x file1.bin file2.bin

You get pretty formatted two columns output where differences are highlighted.

This works for me for aligning the image to center of div.

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

#include <iostream>
#include <sstream>

std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;

while(std::getline(ss, token, ',')) {
    std::cout << token << '\n';
}

abc
def
ghi

You can use a library called select2

You also can look at this Stackoverflow Question & Answer

<select id="selectBox" style="width: 500px">
  <option value="1" data-desc="this is my <br> multiple line 1">option 1</option>
  <option value="2" data-desc="this is my <br> multiple line 2">option 2</option>
</select>

In javascript

$(function(){
  $("#selectBox").select2({
    templateResult: formatDesc
  });

  function formatDesc (opt) {
   var optdesc = $(opt.element).attr('data-desc'); 
    var $opt = $(
      '<div><strong>' + opt.text + '</strong></div><div>' + optdesc + '</div>'
    );
    return $opt;
  };
});

You need to wrap button click handler to match the pattern

public void klik(object sender, EventArgs e)

I was confused about this, too, only a few minutes ago. Then I did the division long-hand on a piece of paper and it made sense:

• 4 goes into 2 zero times.
• 4 times 0 is 0.
• You put that zero under the 2 and subtract which leaves 2.

That's as far as the computer is going to take this problem. The computer stops there and returns the 2, which makes sense since that's what "%" (mod) is asking for.

We've been trained to put in the decimal and keep going which is why this can be counterintuitive at first.

The problem in your code is that you can't store the memory address of a local variable (local to a function, for example) in a globlar variable:

RectInvoice rect(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(&rect);

There, &rect is a temporary address (stored in the function's activation registry) and will be destroyed when that function end.

The code should create a dynamic variable:

RectInvoice *rect =  new RectInvoice(vect,im,x, y, w ,h);
this->rectInvoiceVector.push_back(rect);

There you are using a heap address that will not be destroyed in the end of the function's execution. Tell me if it worked for you.

TLDR:

1. Rebooting both application and DB servers is the quickest fix where data volume, network settings and code haven't changed. We always do so as a rule
2. May be indicator of failing hard-drive that needs replacement - check system notifications

I have often encountered this error for various reasons and have had various solutions, including:

1. refactoring my code to use SqlBulkCopy
2. increasing Timeout values, as stated in various answers or checking for underlying causes (may not be data related)
3. Connection Timeout (Default 15s) - How long it takes to wait for a connection to be established with the SQL server before terminating - TCP/PORT related - can go through a troubleshooting checklist (very handy MSDN article)
4. Command Timeout (Default 30s) - How long it takes to wait for the execution of a query - Query execution/network traffic related - also has a troubleshooting process (another very handy MSDN article)
5. Rebooting of the server(s) - both application & DB Server (if separate) - where code and data haven't changed, environment must have changed - First thing you must do. Typically caused by patches (operating system, .Net Framework or SQL Server patches or updates). Particularly if timeout exception appears as below (even if we do not use Azure):
   • System.Data.Entity.Core.EntityException: An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy. ---> System.Data.Entity.Core.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> System.Data.SqlClient.SqlException: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) ---> System.ComponentModel.Win32Exception: The semaphore timeout period has expired

Also note the CultureInformation of your system. Here my solution without rounding.

In this example you just have to define the variable MyValue as double. As result you get your formatted value in the string variable NewValue.

Note - Also set the C# using statement:

using System.Globalization;  

string MyFormat = "0";
if (MyValue.ToString (CultureInfo.InvariantCulture).Contains (CultureInfo.InvariantCulture.NumberFormat.NumberDecimalSeparator))
   {
      MyFormat += ".00";
   }

string NewValue = MyValue.ToString(MyFormat);

You could try using Linq to project the list:

var output = lst.Select(x => x % 2 == 0).ToList();

This will return a new list of bools such that {1, 2, 3, 4, 5} will map to {false, true, false, true, false}.

Now that the new anaconda individual edition 2020 distribution is out, the procedure that follows is working:

Update conda in your base env:

conda update conda

Create a new environment for Python 3.8, specifying anaconda for the full distribution specification, not just the minimal environment:

conda create -n py38 python=3.8 anaconda

Activate the new environment:

conda activate py38

python --version
Python 3.8.1

Number of packages installed: 303

Or you can do:

conda create -n py38 anaconda=2020.02 python=3.8

--> UPDATE: Finally, Anaconda3-2020.07 is out with core Python 3.8.3

You can download Anaconda with Python 3.8 from https://www.anaconda.com/products/individual

give the LI float: left (or right)

They will all be in the same line until there will be no more room in the container (your case, a ul). (forgot): If you have a block element after the floating elements, he will also stick to them, unless you give him a clear:both, OR put an empty div before it with clear:both

It should be:

...
WHERE LastName LIKE '%' + @LastName + '%';

Instead of:

...
WHERE LastName LIKE '%@LastName%'

It took me few hours to solved this because all off the settings that I found here about this error were the same but it still didn't work. The problem was tha I had a folder in my web service from which the file should be send to WinCE device, after converting that folder to an application with Classic.NetAppPool it started to work.

It depends on the way your page behaves. If you want this to happens asynchronously, you have to use AJAX. Try out "jQuery post()" on Google to find some tuts.

In other case, if this will happen when a user submits a form, you can send the variable in an hidden field or append ?variableName=someValue" to then end of the URL you are opening. :

http://www.somesite.com/send.php?variableName=someValue

or

http://www.somesite.com/send.php?variableName=someValue&anotherVariable=anotherValue

This way, from PHP you can access this value as:

$phpVariableName = $_POST["variableName"];

for forms using POST method or:

$phpVariableName = $_GET["variableName"];

for forms using GET method or the append to url method I've mentioned above (querystring).

Dynamic analysis methods

Here I describe a few dynamic analysis methods.

Dynamic methods actually run the program to determine the call graph.

The opposite of dynamic methods are static methods, which try to determine it from the source alone without running the program.

Advantages of dynamic methods:

• catches function pointers and virtual C++ calls. These are present in large numbers in any non-trivial software.

Disadvantages of dynamic methods:

• you have to run the program, which might be slow, or require a setup that you don't have, e.g. cross-compilation
• only functions that were actually called will show. E.g., some functions could be called or not depending on the command line arguments.

KcacheGrind

https://kcachegrind.github.io/html/Home.html

Test program:

int f2(int i) { return i + 2; }
int f1(int i) { return f2(2) + i + 1; }
int f0(int i) { return f1(1) + f2(2); }
int pointed(int i) { return i; }
int not_called(int i) { return 0; }

int main(int argc, char **argv) {
    int (*f)(int);
    f0(1);
    f1(1);
    f = pointed;
    if (argc == 1)
        f(1);
    if (argc == 2)
        not_called(1);
    return 0;
}

Usage:

sudo apt-get install -y kcachegrind valgrind

# Compile the program as usual, no special flags.
gcc -ggdb3 -O0 -o main -std=c99 main.c

# Generate a callgrind.out.<PID> file.
valgrind --tool=callgrind ./main

# Open a GUI tool to visualize callgrind data.
kcachegrind callgrind.out.1234

You are now left inside an awesome GUI program that contains a lot of interesting performance data.

On the bottom right, select the "Call graph" tab. This shows an interactive call graph that correlates to performance metrics in other windows as you click the functions.

To export the graph, right click it and select "Export Graph". The exported PNG looks like this:

From that we can see that:

• the root node is _start, which is the actual ELF entry point, and contains glibc initialization boilerplate
• f0, f1 and f2 are called as expected from one another
• pointed is also shown, even though we called it with a function pointer. It might not have been called if we had passed a command line argument.
• not_called is not shown because it didn't get called in the run, because we didn't pass an extra command line argument.

The cool thing about valgrind is that it does not require any special compilation options.

Therefore, you could use it even if you don't have the source code, only the executable.

valgrind manages to do that by running your code through a lightweight "virtual machine". This also makes execution extremely slow compared to native execution.

As can be seen on the graph, timing information about each function call is also obtained, and this can be used to profile the program, which is likely the original use case of this setup, not just to see call graphs: How can I profile C++ code running on Linux?

Tested on Ubuntu 18.04.

gcc -finstrument-functions + etrace

-finstrument-functions adds callbacks, etrace parses the ELF file and implements all callbacks.

I couldn't get it working however unfortunately: Why doesn't `-finstrument-functions` work for me?

Claimed output is of format:

|   |   |   \-- Crumble_bake

Likely the most efficient method besides specific hardware tracing support, but has the downside that you have to recompile the code.

Declare systemStatus in an outer scope and assign it in an onload handler.

systemStatus = null;

function onloadHandler(evt) {
    systemStatus = document.getElementById("....");
}

Or if you don't want the onload handler, put your script tag at the bottom of your HTML.

I encountered this error when I hooked a UIButton to a storyboard segue action (in IB) but later decided to have the button programatically call performSegueWithIdentifier forgetting to remove the first one from IB.

In essence it performed the segue call twice, gave this error and actually pushed my view twice. The fix was to remove one of the segue calls.

Hope this helps someone as tired as me!

Most browsers will let you put very large amounts of data in a URL and thus lots of things end up creating very large URLs so if you are talking about anything more than the domain part of a URL you will need to use a TEXT column since the VARCHAR/CHAR are limited.

PostgreSQL supports schemas, which is a subset of a database: https://www.postgresql.org/docs/current/static/ddl-schemas.html

A database contains one or more named schemas, which in turn contain tables. Schemas also contain other kinds of named objects, including data types, functions, and operators. The same object name can be used in different schemas without conflict; for example, both schema1 and myschema can contain tables named mytable. Unlike databases, schemas are not rigidly separated: a user can access objects in any of the schemas in the database they are connected to, if they have privileges to do so.

Schemas are analogous to directories at the operating system level, except that schemas cannot be nested.

In my humble opinion, MySQL is not a reference database. You should never quote MySQL for an explanation. MySQL implements non-standard SQL and sometimes claims features that it does not support. For example, in MySQL, CREATE schema will only create a DATABASE. It is truely misleading users.

This kind of vocabulary is called "MySQLism" by DBAs.

For reference, these are very similar questions.

These seem to work the best for me. They also work with spaces, and don't re-add ignored files. I didn't see them listed on any of the other answers I saw.

adding:

svn st | grep ^? | sed 's/?    //' | xargs svn add

removing:

svn st | grep ^! | sed 's/!    //' | xargs svn rm

Edit: It's important to NOT use "add *" if you want to keep your ignored files, otherwise everything that was ignored will be re-added.

I know its too longtime to reply but just as an information purpose for future readers:

WebRequest

System.Object
    System.MarshalByRefObject
        System.Net.WebRequest

The WebRequest is an abstract base class. So you actually don't use it directly. You use it through it derived classes - HttpWebRequest and FileWebRequest.

You use Create method of WebRequest to create an instance of WebRequest. GetResponseStream returns data stream.

There are also FileWebRequest and FtpWebRequest classes that inherit from WebRequest. Normally, you would use WebRequest to, well, make a request and convert the return to either HttpWebRequest, FileWebRequest or FtpWebRequest, depend on your request. Below is an example:

Example:

var _request = (HttpWebRequest)WebRequest.Create("http://stackverflow.com");
var _response = (HttpWebResponse)_request.GetResponse();

WebClient

System.Object
        System.MarshalByRefObject
            System.ComponentModel.Component
                System.Net.WebClient

WebClient provides common operations to sending and receiving data from a resource identified by a URI. Simply, it’s a higher-level abstraction of HttpWebRequest. This ‘common operations’ is what differentiate WebClient from HttpWebRequest, as also shown in the sample below:

Example:

var _client = new WebClient();
var _stackContent = _client.DownloadString("http://stackverflow.com");

There are also DownloadData and DownloadFile operations under WebClient instance. These common operations also simplify code of what we would normally do with HttpWebRequest. Using HttpWebRequest, we have to get the response of our request, instantiate StreamReader to read the response and finally, convert the result to whatever type we expect. With WebClient, we just simply call DownloadData, DownloadFile or DownloadString.

However, keep in mind that WebClient.DownloadString doesn’t consider the encoding of the resource you requesting. So, you would probably end up receiving weird characters if you don’t specify and encoding.

NOTE: Basically "WebClient takes few lines of code as compared to Webrequest"

This can be done with lodash _.last or _.nth:

var data = [1, 2, 3, 4]_x000D_
var last = _.nth(data, -1)_x000D_
console.log(last)

Ease of use

The analytic and synthetic reasons were already mentioned. For newcomers there's a more significant incentive to stop using the dated mysql_ functions.

Contemporary database APIs are just easier to use.

It's mostly the bound parameters which can simplify code. And with excellent tutorials (as seen above) the transition to PDO isn't overly arduous.

Rewriting a larger code base at once however takes time. Raison d'être for this intermediate alternative:

Equivalent pdo_* functions in place of mysql_*

Using <pdo_mysql.php> you can switch from the old mysql_ functions with minimal effort. It adds pdo_ function wrappers which replace their mysql_ counterparts.

1. Simply include_once("pdo_mysql.php"); in each invocation script that has to interact with the database.
   

2. Remove the mysql_ function prefix everywhere and replace it with pdo_.

   • mysql_connect() becomes pdo_connect()
   • mysql_query() becomes pdo_query()
   • mysql_num_rows() becomes pdo_num_rows()
   • mysql_insert_id() becomes pdo_insert_id()
   • mysql_fetch_array() becomes pdo_fetch_array()
   • mysql_fetch_assoc() becomes pdo_fetch_assoc()
   • mysql_real_escape_string() becomes pdo_real_escape_string()
   • and so on...
     
     

3. Your code will work alike and still mostly look the same:

   include_once("pdo_mysql.php"); 
   
   pdo_connect("localhost", "usrABC", "pw1234567");
   pdo_select_db("test");
   
   $result = pdo_query("SELECT title, html FROM pages");  
   
   while ($row = pdo_fetch_assoc($result)) {
       print "$row[title] - $row[html]";
   }
   

Et voilà.
Your code is using PDO.
Now it's time to actually utilize it.

Bound parameters can be easy to use

You just need a less unwieldy API.

pdo_query() adds very facile support for bound parameters. Converting old code is straightforward:

Move your variables out of the SQL string.

• Add them as comma delimited function parameters to pdo_query().
• Place question marks ? as placeholders where the variables were before.
• Get rid of ' single quotes that previously enclosed string values/variables.

The advantage becomes more obvious for lengthier code.

Often string variables aren't just interpolated into SQL, but concatenated with escaping calls in between.

pdo_query("SELECT id, links, html, title, user, date FROM articles
   WHERE title='" . pdo_real_escape_string($title) . "' OR id='".
   pdo_real_escape_string($title) . "' AND user <> '" .
   pdo_real_escape_string($root) . "' ORDER BY date")

With ? placeholders applied you don't have to bother with that:

pdo_query("SELECT id, links, html, title, user, date FROM articles
   WHERE title=? OR id=? AND user<>? ORDER BY date", $title, $id, $root)

Remember that pdo_* still allows either or.
Just don't escape a variable and bind it in the same query.

• The placeholder feature is provided by the real PDO behind it.
• Thus also allowed :named placeholder lists later.

More importantly you can pass $_REQUEST[] variables safely behind any query. When submitted <form> fields match the database structure exactly it's even shorter:

pdo_query("INSERT INTO pages VALUES (?,?,?,?,?)", $_POST);

So much simplicity. But let's get back to some more rewriting advises and technical reasons on why you may want to get rid of mysql_ and escaping.

Fix or remove any oldschool sanitize() function

Once you have converted all mysql_ calls to pdo_query with bound params, remove all redundant pdo_real_escape_string calls.

In particular you should fix any sanitize or clean or filterThis or clean_data functions as advertised by dated tutorials in one form or the other:

function sanitize($str) {
   return trim(strip_tags(htmlentities(pdo_real_escape_string($str))));
}

Most glaring bug here is the lack of documentation. More significantly the order of filtering was in exactly the wrong order.

• Correct order would have been: deprecatedly stripslashes as the innermost call, then trim, afterwards strip_tags, htmlentities for output context, and only lastly the _escape_string as its application should directly preceed the SQL intersparsing.

• But as first step just get rid of the _real_escape_string call.

• You may have to keep the rest of your sanitize() function for now if your database and application flow expect HTML-context-safe strings. Add a comment that it applies only HTML escaping henceforth.

• String/value handling is delegated to PDO and its parameterized statements.

• If there was any mention of stripslashes() in your sanitize function, it may indicate a higher level oversight.

  • That was commonly there to undo damage (double escaping) from the deprecated magic_quotes. Which however is best fixed centrally, not string by string.

  • Use one of the userland reversal approaches. Then remove the stripslashes() in the sanitize function.

  Historic note on magic_quotes. That feature is rightly deprecated. It's often incorrectly portrayed as failed security feature however. But magic_quotes are as much a failed security feature as tennis balls have failed as nutrition source. That simply wasn't their purpose.

  The original implementation in PHP2/FI introduced it explicitly with just "quotes will be automatically escaped making it easier to pass form data directly to msql queries". Notably it was accidentially safe to use with mSQL, as that supported ASCII only.
  Then PHP3/Zend reintroduced magic_quotes for MySQL and misdocumented it. But originally it was just a convenience feature, not intend for security.

How prepared statements differ

When you scramble string variables into the SQL queries, it doesn't just get more intricate for you to follow. It's also extraneous effort for MySQL to segregate code and data again.

SQL injections simply are when data bleeds into code context. A database server can't later spot where PHP originally glued variables inbetween query clauses.

With bound parameters you separate SQL code and SQL-context values in your PHP code. But it doesn't get shuffled up again behind the scenes (except with PDO::EMULATE_PREPARES). Your database receives the unvaried SQL commands and 1:1 variable values.

While this answer stresses that you should care about the readability advantages of dropping mysql_. There's occasionally also a performance advantage (repeated INSERTs with just differing values) due to this visible and technical data/code separation.

Beware that parameter binding still isn't a magic one-stop solution against all SQL injections. It handles the most common use for data/values. But can't whitelist column name / table identifiers, help with dynamic clause construction, or just plain array value lists.

Hybrid PDO use

These pdo_* wrapper functions make a coding-friendly stop-gap API. (It's pretty much what MYSQLI could have been if it wasn't for the idiosyncratic function signature shift). They also expose the real PDO at most times.
Rewriting doesn't have to stop at using the new pdo_ function names. You could one by one transition each pdo_query() into a plain $pdo->prepare()->execute() call.

It's best to start at simplifying again however. For example the common result fetching:

$result = pdo_query("SELECT * FROM tbl");
while ($row = pdo_fetch_assoc($result)) {

Can be replaced with just an foreach iteration:

foreach ($result as $row) {

Or better yet a direct and complete array retrieval:

$result->fetchAll();

You'll get more helpful warnings in most cases than PDO or mysql_ usually provide after failed queries.

Other options

So this hopefully visualized some practical reasons and a worthwile pathway to drop mysql_.

Just switching to pdo doesn't quite cut it. pdo_query() is also just a frontend onto it.

Unless you also introduce parameter binding or can utilize something else from the nicer API, it's a pointless switch. I hope it's portrayed simple enough to not further the discouragement to newcomers. (Education usually works better than prohibition.)

While it qualifies for the simplest-thing-that-could-possibly-work category, it's also still very experimental code. I just wrote it over the weekend. There's a plethora of alternatives however. Just google for PHP database abstraction and browse a little. There always have been and will be lots of excellent libraries for such tasks.

If you want to simplify your database interaction further, mappers like Paris/Idiorm are worth a try. Just like nobody uses the bland DOM in JavaScript anymore, you don't have to babysit a raw database interface nowadays.

Swift 3.0 version

let arr = yourString.components(separatedBy: "/")
let month = arr[0]

If there is space between the letters of the font, you need to use quote.

font-family:"Calibri (Body)";

public class Foo {
    public int bar;
    public int stuff;
};

void Main()
{
    List<Foo> fooList = new List<Foo>(){
    new Foo(){bar=1,stuff=2},
    new Foo(){bar=3,stuff=4},
    new Foo(){bar=2,stuff=3}};

    Foo result = fooList.Aggregate((u,v) => u.bar < v.bar ? u: v);
    result.Dump();
}

There is a clean, one-line way of doing this in Pandas:

df['col_3'] = df.apply(lambda x: f(x.col_1, x.col_2), axis=1)

This allows f to be a user-defined function with multiple input values, and uses (safe) column names rather than (unsafe) numeric indices to access the columns.

Example with data (based on original question):

import pandas as pd

df = pd.DataFrame({'ID':['1', '2', '3'], 'col_1': [0, 2, 3], 'col_2':[1, 4, 5]})
mylist = ['a', 'b', 'c', 'd', 'e', 'f']

def get_sublist(sta,end):
    return mylist[sta:end+1]

df['col_3'] = df.apply(lambda x: get_sublist(x.col_1, x.col_2), axis=1)

Output of print(df):

  ID  col_1  col_2      col_3
0  1      0      1     [a, b]
1  2      2      4  [c, d, e]
2  3      3      5  [d, e, f]

If your column names contain spaces or share a name with an existing dataframe attribute, you can index with square brackets:

df['col_3'] = df.apply(lambda x: f(x['col 1'], x['col 2']), axis=1)

you can use list to define it.

objs = list()
for i in range(10):
    objs.append(MyClass())

You often see the check for definedness so you don't have to deal with the warning for using an undef value (and in Perl 5.10 it tells you the offending variable):

 Use of uninitialized value $name in ...

So, to get around this warning, people come up with all sorts of code, and that code starts to look like an important part of the solution rather than the bubble gum and duct tape that it is. Sometimes, it's better to show what you are doing by explicitly turning off the warning that you are trying to avoid:

 {
 no warnings 'uninitialized';

 if( length $name ) {
      ...
      }
 }

In other cases, use some sort of null value instead of the data. With Perl 5.10's defined-or operator, you can give length an explicit empty string (defined, and give back zero length) instead of the variable that will trigger the warning:

 use 5.010;

 if( length( $name // '' ) ) {
      ...
      }

In Perl 5.12, it's a bit easier because length on an undefined value also returns undefined. That might seem like a bit of silliness, but that pleases the mathematician I might have wanted to be. That doesn't issue a warning, which is the reason this question exists.

use 5.012;
use warnings;

my $name;

if( length $name ) { # no warning
    ...
    }

Pure/vanilla JS solution (working example here)

// All elements with data-company="Microsoft" below "Companies"
let a = document.querySelectorAll("[data-group='Companies'] [data-company='Microsoft']"); 

// All elements with data-company!="Microsoft" below "Companies"
let b = document.querySelectorAll("[data-group='Companies'] :not([data-company='Microsoft'])"); 

In querySelectorAll you must use valid CSS selector (currently Level3)

SPEED TEST (2018.06.29) for jQuery and Pure JS: test was performed on MacOs High Sierra 10.13.3 on Chrome 67.0.3396.99 (64-bit), Safari 11.0.3 (13604.5.6), Firefox 59.0.2 (64-bit). Below screenshot shows results for fastest browser (Safari):

PureJS was faster than jQuery about 12% on Chrome, 21% on Firefox and 25% on Safari. Interestingly speed for Chrome was 18.9M operation per second, Firefox 26M, Safari 160.9M (!).

So winner is PureJS and fastest browser is Safari (more than 8x faster than Chrome!)

Here you can perform test on your machine: https://jsperf.com/js-selectors-x

You can use nestedvm to translate C (or other GCC languages) into Java bytecode, and use that as the basis of your port. For example, see the Android port of Simon Tathams portable puzzle collection.

I expect this method is made obsolete by the NDK, but it might not be in if some networks or something don't allow people to upgrade their phones.

Maybe call Directory.GetParent in a loop? That's if you want the full path to each directory and not just the directory names.

I suggest to instead this lines

<div>
    <asp:TextBox runat="server" ID="username" />
    <asp:RequiredFieldValidator ErrorMessage="The username is required" ControlToValidate="username" runat="server" Text=" - Required" />
</div>

by this line

<div>
    <asp:TextBox runat="server" ID="username" required />
</div>

Here it is, in as few words as possible. Focus on characters that need no escaping:

For cookies:

abdefghijklmnqrstuvxyzABDEFGHIJKLMNQRSTUVXYZ0123456789!#$%&'()*+-./:<>?@[]^_`{|}~

For urls

abdefghijklmnqrstuvxyzABDEFGHIJKLMNQRSTUVXYZ0123456789.-_~!$&'()*+,;=:@

For cookies and urls ( intersection )

abdefghijklmnqrstuvxyzABDEFGHIJKLMNQRSTUVXYZ0123456789!$&'()*+-.:@_~

That's how you answer.

Note that for cookies, the = has been removed because it is usually used to set the cookie value.

For urls this the = was kept. The intersection is obviously without.

var chars = "abdefghijklmnqrstuvxyz"; chars += chars.toUpperCase() + "0123456789" + "!$&'()*+-.:@_~";

Turns out escaping still occuring and unexpected happening, especially in a Java cookie environment where the cookie is wrapped with double quotes if it encounters the last characters.

So to be safe, just use A-Za-z1-9. That's what I am going to do.

I got your problem , and here is my answer:

prices = [5, 12, 45]
list=['1','2','3']

for i in range(1,3):
  vars()["prices"+list[0]]=prices[0]
print ("prices[i]=" +prices[i])

so while printing:

price1 = 5 
price2 = 12
price3 = 45

The meaning of an AssertionError is that something happened that the developer thought was impossible to happen.

So if an AssertionError is ever thrown, it is a clear sign of a programming error.

string s = String.Concat(myObj);

would be the shortest way I guess and also have neglible performance overhead. Keep in mind though it wouldn't be quite clear for the reader of the code what the intention is.

Try the following configuration:

log4j.rootLogger=TRACE, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.debugLog=org.apache.log4j.FileAppender
log4j.appender.debugLog.File=logs/debug.log
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.reportsLog=org.apache.log4j.FileAppender
log4j.appender.reportsLog.File=logs/reports.log
log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout
log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false

log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false

Then configure the loggers in the Java code accordingly:

static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");

Do you want output to go to stdout? If not, change the first line of log4j.properties to:

log4j.rootLogger=OFF

and get rid of the stdout lines.

You can change the code by using class definition for the i element:

<a href="javascript:void"><i class="fa fa-plus-circle"></i>Category 1</a>

Then you can switch the classes rapresenting the plus/minus state using toggleClass with multiple classes:

$('#category-tabs li a').click(function(){
    $(this).next('ul').slideToggle('500');
    $(this).find('i').toggleClass('fa-plus-circle fa-minus-circle');
});

Demo: http://jsfiddle.net/Zcn2u/

You can iterate over a dictionary and grab an index with for-in and enumerate (like others have said, there is no guarantee it will come out ordered like below)

let dict = ["c": 123, "d": 045, "a": 456]

for (index, entry) in enumerate(dict) {
    println(index)   // 0       1        2
    println(entry)   // (d, 45) (c, 123) (a, 456)
}

If you want to sort first..

var sortedKeysArray = sorted(dict) { $0.0 < $1.0 }
println(sortedKeysArray)   // [(a, 456), (c, 123), (d, 45)]

var sortedValuesArray = sorted(dict) { $0.1 < $1.1 }
println(sortedValuesArray) // [(d, 45), (c, 123), (a, 456)]

then iterate.

for (index, entry) in enumerate(sortedKeysArray) {
    println(index)    // 0   1   2
    println(entry.0)  // a   c   d
    println(entry.1)  // 456 123 45
}

If you want to create an ordered dictionary, you should look into Generics.

Parsing the Feed

With jQuery's jFeed

_{(Don't really recommend that one, see the other options.)}

jQuery.getFeed({
   url     : FEED_URL,
   success : function (feed) {
      console.log(feed.title);
      // do more stuff here
   }
});

With jQuery's Built-in XML Support

$.get(FEED_URL, function (data) {
    $(data).find("entry").each(function () { // or "item" or whatever suits your feed
        var el = $(this);

        console.log("------------------------");
        console.log("title      : " + el.find("title").text());
        console.log("author     : " + el.find("author").text());
        console.log("description: " + el.find("description").text());
    });
});

With jQuery and the Google AJAX Feed API

$.ajax({
  url      : document.location.protocol + '//ajax.googleapis.com/ajax/services/feed/load?v=1.0&num=10&callback=?&q=' + encodeURIComponent(FEED_URL),
  dataType : 'json',
  success  : function (data) {
    if (data.responseData.feed && data.responseData.feed.entries) {
      $.each(data.responseData.feed.entries, function (i, e) {
        console.log("------------------------");
        console.log("title      : " + e.title);
        console.log("author     : " + e.author);
        console.log("description: " + e.description);
      });
    }
  }
});

But that means you're relient on them being online and reachable.

Building Content

Once you've successfully extracted the information you need from the feed, you could create DocumentFragments (with document.createDocumentFragment() containing the elements (created with document.createElement()) you'll want to inject to display your data.

Injecting the content

Select the container element that you want on the page and append your document fragments to it, and simply use innerHTML to replace its content entirely.

Something like:

$('#rss-viewer').append(aDocumentFragmentEntry);

or:

$('#rss-viewer')[0].innerHTML = aDocumentFragmentOfAllEntries.innerHTML;

&lt;p&gt;Otherwise, &lt;a href=&quot;https://developers.google.com/feed/&quot; rel=&quot;nofollow&quot;&gt;Google&#39;s AJAX Feed API&lt;/a&gt; allows you to get the feed as a JSON object:&lt;/p&gt;

  dataType : &#39;json&#39;,
  success  : function (data) {
    if (data.responseData.feed &amp;amp;&amp;amp; data.responseData.feed.entries) {
      $.each(data.responseData.feed.entries, function (i, e) {
        console.log(&quot;------------------------&quot;);
        console.log(&quot;title      : &quot; + e.title);
        console.log(&quot;author     : &quot; + e.author);

Did you restart the server after you changed the config file?

Can you telnet to the server from a different machine?

Can you telnet to the server from the server itself?

telnet <ip address> 80

telnet localhost 80

The only software that I found that already exists is Matrox PowerDesk. Among other things it lets you split a monitor into 2 virtual desktops. You have to have a compatible matrox video card though. It also does a bunch of other multi-monitor functions.

I solved this problem by: `

@Bean
CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    configuration.setAllowedOrigins(Arrays.asList("*"));
    configuration.setAllowCredentials(true);
    configuration.setAllowedHeaders(Arrays.asList("Access-Control-Allow-Headers","Access-Control-Allow-Origin","Access-Control-Request-Method", "Access-Control-Request-Headers","Origin","Cache-Control", "Content-Type", "Authorization"));
    configuration.setAllowedMethods(Arrays.asList("DELETE", "GET", "POST", "PATCH", "PUT"));
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

Try to look at Net2Java It seems to me the best option for automatic (or semi-automatic at least) conversion from C# to Java

This answer relevant for Vue.js version 2

<th 
  class="initial " 
  v-on:click="myFilter"
  v-bind:class="{ active: isActive }"
>
  <span class="wkday">M</span>
</th>

The rest of the answer by Douglas is still applicable (setting up the new Vue instance with isActive: false, etc).

Relevant docs: https://vuejs.org/v2/guide/class-and-style.html#Object-Syntax and https://vuejs.org/v2/guide/events.html#Method-Event-Handlers

You can simply use $pull to remove a sub-document. The $pull operator removes from an existing array all instances of a value or values that match a specified condition.

Collection.update({
    _id: parentDocumentId
  }, {
    $pull: {
      subDocument: {
        _id: SubDocumentId
      }
    }
  });

This will find your parent document against given ID and then will remove the element from subDocument which matched the given criteria.

Read more about pull here.

I solve such queries using this pattern:

SELECT *
FROM t
WHERE t.field=(
  SELECT MAX(t.field) 
  FROM t AS t0 
  WHERE t.group_column1=t0.group_column1
    AND t.group_column2=t0.group_column2 ...)

That is it will select records where the value of a field is at its max value. To apply it to your query I used the common table expression so that I don't have to repeat the JOIN twice:

WITH site_history AS (
  SELECT sites.siteName, sites.siteIP, history.date
  FROM sites
  JOIN history USING (siteName)
)
SELECT *
FROM site_history h
WHERE date=(
  SELECT MAX(date) 
  FROM site_history h0 
  WHERE h.siteName=h0.siteName)
ORDER BY siteName

It's important to note that it works only if the field we're calculating the maximum for is unique. In your example the date field should be unique for each siteName, that is if the IP can't be changed multiple times per millisecond. In my experience this is commonly the case otherwise you don't know which record is the newest anyway. If the history table has an unique index for (site, date), this query is also very fast, index range scan on the history table scanning just the first item can be used.

Remember that the US date format is different from the UK. Using the UK format, it needs to be, e.g.

--                                  dd/mm/ccyy hh:mm:ss     
dbo.no_time(at.date_stamp) between '22/05/2016 00:00:01' and '22/07/2016 23:59:59' 

If you don't want to bother with weird expansions from bash you can do this

me$ FOO="BAR \x2A BAR"   # 2A is hex code for *
me$ echo -e $FOO
BAR * BAR
me$ 

Explanation here why using -e option of echo makes life easier:

Relevant quote from man here:

SYNOPSIS
   echo [SHORT-OPTION]... [STRING]...
   echo LONG-OPTION

DESCRIPTION
   Echo the STRING(s) to standard output.

   -n     do not output the trailing newline

   -e     enable interpretation of backslash escapes

   -E     disable interpretation of backslash escapes (default)

   --help display this help and exit

   --version
          output version information and exit

   If -e is in effect, the following sequences are recognized:

   \\     backslash

   ...

   \0NNN  byte with octal value NNN (1 to 3 digits)

   \xHH   byte with hexadecimal value HH (1 to 2 digits)

For the hex code you can check man ascii page (first line in octal, second decimal, third hex):

   051   41    29    )                           151   105   69    i
   052   42    2A    *                           152   106   6A    j
   053   43    2B    +                           153   107   6B    k

Swift 3.0

if NSUserDefaults.standardUserDefaults().dictionaryRepresentation().contains({ $0.0 == "Your_Comparison_Key" }){
                    result = NSUserDefaults.standardUserDefaults().objectForKey(self.ticketDetail.ticket_id) as! String
                }

I presume you mean via SSMS?

For a SQL Server Instance:

SELECT SERVERPROPERTY('productversion'), 
       SERVERPROPERTY ('productlevel'), 
       SERVERPROPERTY ('edition')

For a SQL Server Installation:

Select @@Version

#sorting first by age then profession,you can change it in function "fun".
a = []

def fun(v):
    return (v[1],v[2])

# create the table (name, age, job)
a.append(["Nick", 30, "Doctor"])
a.append(["John",  8, "Student"])
a.append(["Paul",  8,"Car Dealer"])
a.append(["Mark", 66, "Retired"])

a.sort(key=fun)


print a

How about .toDateString()?

Alternatively, use .getDate(), .getMonth(), and .getYear()?

In my mind, if you want to group things by date, you simply want to access the date, not set it. Through having some set way of accessing the date field, you can compare them and group them together, no?

Check out all the fun Date methods here: MDN Docs

Edit: If you want to keep it as a date object, just do this:

var newDate = new Date(oldDate.toDateString());

Date's constructor is pretty smart about parsing Strings (though not without a ton of caveats, but this should work pretty consistently), so taking the old Date and printing it to just the date without any time will result in the same effect you had in the original post.

@Michiel is correct to create a button but the code for ActionScript 3 it is a little different - where movieClipName is the name of your 'button'.

movieClipName.addEventListener(MouseEvent.CLICK, callLink);
function callLink:void {
  var url:String = "http://site";
  var request:URLRequest = new URLRequest(url);
  try {
    navigateToURL(request, '_blank');
  } catch (e:Error) {
    trace("Error occurred!");
  }
}

GET takes name value pairs.

Try something like:

curl http://server:5050/a/c/getName/?param1=pradeep

or

curl http://server:5050/a/c/getName?param1=pradeep

btw a regular REST should look something like

curl http://server:5050/a/c/getName/pradeep If it takes JSON in GET URL, it's not a standard way.

Just found the thing needed. Now, I can store products visited on cookies and show them later when they get back to the site.

// set the cookies
setcookie("product[cookiethree]", "cookiethree");
setcookie("product[cookietwo]", "cookietwo");
setcookie("product[cookieone]", "cookieone");

// after the page reloads, print them out
if (isset($_COOKIE['product'])) {
    foreach ($_COOKIE['product'] as $name => $value) {
        $name = htmlspecialchars($name);
        $value = htmlspecialchars($value);
        echo "$name : $value <br />\n";
    }
}

Try installing the 'Application Development' sub component of IIS as mentioned in this SO

• Click "Start button" in the search box, enter "Turn windows features on or off"
• in the features window, Click: "Internet Information Services"
• Click: "World Wide Web Services"
• Click: "Application Development Features"
• Check (enable) the features. I checked all but CGI.

With the latest NodeJS you can experiment with this monkey patch:

const http = require("http");
const originalOnSocket = http.ClientRequest.prototype.onSocket;
require("http").ClientRequest.prototype.onSocket = function(socket) {
    const that = this;
    socket.setTimeout(this.timeout ? this.timeout : 3000);
    socket.on('timeout', function() {
        that.abort();
    });
    originalOnSocket.call(this, socket);
};

The best way is to use your code and then store the image in OG tags in the page you are linking to, then Facebook will pick them up.

<meta property="og:title" content="Facebook Open Graph Demo">
<meta property="og:image" content="http://example.com/main-image.png">
<meta property="og:site_name" content="Example Website">
<meta property="og:description" content="Here is a nice description">

You can find documentation to OG tags and how to use them with share buttons here

Howabout Bugzilla. Open source and what Mozilla uses.

@NoCanDo: You cannot create an array with different data types because java only supports variables with a specific data type or object. When you are creating an array, you are pulling together an assortment of similar variables -- almost like an extended variable. All of the variables must be of the same type therefore. Java cannot differentiate the data type of your variable unless you tell it what it is. Ex: int tells all your variables declared to it are of data type int. What you could do is create 3 arrays with corresponding information.

Now, a single index number gives you all the info for that book. Ex: All of your arrays with index number 0 ([0]) have information for book 1.

If you are looking for a direct approach and using a local File in that case. Try

<div
style={{ background-image: 'url(' + Image + ')', background-size: 'auto' }}
/>

This is the case of JS with inline styling where Image is a local file that you must have imported with a path.
