Try this one Open your projectname.csproj file its work for me.

<PackageReference Include="System.Data.SqlClient" Version="4.6.0" />

You need to add this Reference "ItemGroup" tag inside.

var arr = [ 'a', 'b', 'c'];
arr.push('d'); // insert as last item

Something like this should work:

INSERT INTO #IMEIS (imei) VALUES ('val1'), ('val2'), ...

UPDATE:

Apparently this syntax is only available starting on SQL Server 2008.

Try:

SELECT
    *
FROM
    YourTable
WHERE
    CHAR_LENGTH(Link) > x

For me the 'Bla' file was System.Net.http dll which was missing from my BIN folder. I just added it and it worked fine. Didn't change any registry key or anything of that sort.

This still appears to be an issue, causing package installations to be aborted with warnings about optional packages no being installed because of "Unsupported platform".

The problem relates to the "shrinkwrap" or package-lock.json which gets persisted after every package manager execution. Subsequent attempts keep failing as this file is referenced instead of package.json.

Adding these options to the npm install command should allow packages to install again.

   --no-optional argument will prevent optional dependencies from being installed.

   --no-shrinkwrap argument, which will ignore an available package lock or
                   shrinkwrap file and use the package.json instead.

   --no-package-lock argument will prevent npm from creating a package-lock.json file.

The complete command looks like this:

    npm install --no-optional --no-shrinkwrap --no-package-lock

nJoy!

To get rid of the default dropdown arrow use:

-moz-appearance: window; 

Actually, it's because CSS defines 100% relative to the entire width of the container, including its margins, borders, and padding; that means that the space avail. to its contents is some amount smaller than 100%, unless the container has no margins, borders, or padding.

This is counter-intuitive and widely regarded by many to be a mistake that we are now stuck with. It effectively means that % dimensions are no good for anything other than a top level container, and even then, only if it has no margins, borders or padding.

Note that the text field's margins, borders, and padding are included in the CSS size specified for it - it's the container's which throw things off.

I have tolerably worked around it by using 98%, but that is a less than perfect solution, since the input fields tend to fall further short as the container gets larger.

EDIT: I came across this similar question - I've never tried the answer given, and I don't know for sure if it applies to your problem, but it seems like it will.

try this : here select is your select element

let select = document.getElementsByClassName('lstSelected')[0],
    options = select.options,
    len = options.length,
    data='',
    i=0;
while (i<len){
    if (options[i].selected)
        data+= "&" + select.name + '=' + options[i].value;
    i++;
}
return data;

Data is in the form of query string i.e.name=value&name=anotherValue

Günter's answer is great (question is asking for dynamic class attribute) but I thought I would add just for completeness...

If you're looking for a quick and clean way to add one or more static classes to the host element of your component (i.e., for theme-styling purposes) you can just do:

@Component({
   selector: 'my-component',
   template: 'app-element',
   host: {'class': 'someClass1'}
})
export class App implements OnInit {
...
}

And if you use a class on the entry tag, Angular will merge the classes, i.e.,

<my-component class="someClass2">
  I have both someClass1 & someClass2 applied to me
</my-component>

I didn't know about iterators, however here's what I was doing until today to remove elements from a list inside a loop:

List<String> names = .... 
for (i=names.size()-1;i>=0;i--) {    
    // Do something    
    names.remove(i);
} 

This is always working, and could be used in other languages or structs not supporting iterators.

Just use

..............

self::index();

..............

So here is an idea!

Since it seemed to work somewhere else.

install python-virtualenv and optionally you can install virtualenv-wrapper (which is pretty cool to create projects and so on)

In each env, you might have different versions of eggs. In other word, you could have sqlalchemy 1 and sqlaclhemy 1.5 in two different envs and they won't conflict with each others. It seems that you have a problem with your currently installed eggs.

So here we go:

virtualenv --no-site-packages foo
source foo/bin/activate

The parameter --no-site-packages will create a virtualenv and not use the packages already installed on your computer. It's pretty much like a bare python install.

source foo/bin/activate loads the virtualenv.

It's not that really userfriendly. And that's why http://www.doughellmann.com/projects/virtualenvwrapper/ exists.

That said, you should see somthing like thant in your terminal "(foo)user@domain$:" once your virtualenv is activated. It means that you can go on!

Then you have to do.

python setup.py develop of your project. It should download and install dependencies of your project in the virtualenv located in foo. If you need to install anything else, please use pip or easy_install without using sudo. When using virtualenv, you almost never need to use sudo. Sudo will install package in your global python install while it's not required and not really desirable.

If something happens in your virtualenv, you can always delete it and create a new one. This is no big deal. No need to mess with anything. Doesn't work? start over, do pip install -U if needed, define the versions if needed and so on.

Last but not least, in the other answers, it seems that the import changed. If the new versions for flask-sqlalchemy is located somewhere else, you should update your import or install the version you used to use.

echo "<pre>";
print_r($this->session->all_userdata());
echo "</pre>";

Display yet formatting then you can view properly.

Please never do this in real projects:

document.getElementById("span").innerHTML = "String".fontsize(25);

<span id="span"></span>

I am running kepler in ubuntu and had the same problem getting eclipse to recognize the tomcat7 server. My path to install directory was fine and deleting/renaming the files only did not fix it either.

This is what worked for me:

run the following in terminal:

cd ~/workspace/.metadata/.plugins/org.eclipse.core.runtime/.settings/    
rm org.eclipse.jst.server.tomcat.core.prefs    
rm org.eclipse.wst.server.core.prefs
cd /usr/share/tomcat7
sudo service tomcat7 stop
sudo update-rc.d tomcat7 disable
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo ln -s /var/log/tomcat7 log
sudo chmod -R 777 /usr/share/tomcat7/conf
sudo ln -s /var/lib/tomcat7/common common
sudo ln -s /var/lib/tomcat7/server server
sudo ln -s /var/lib/tomcat7/shared shared

restart eclipse, delete tomcat7 server. Re-add server and everything then worked.

Here is the link I used. http://linux.mjnet.eu/post/1319/tomcat-7-ubuntu-13-04-and-eclipse-kepler-problem-to-run/

As documented under CREATE TABLE Syntax:

Note
The older TYPE option was synonymous with ENGINE. TYPE was deprecated in MySQL 4.0 and removed in MySQL 5.5. When upgrading to MySQL 5.5 or later, you must convert existing applications that rely on TYPE to use ENGINE instead.

Therefore, you want:

CREATE TABLE dave_bannedwords(
  id   INT(11)     NOT NULL AUTO_INCREMENT,
  word VARCHAR(60) NOT NULL DEFAULT '',
  PRIMARY KEY (id),
  KEY id(id) -- this is superfluous in the presence of your PK, ergo unnecessary
) ENGINE = MyISAM ;

you are getting math domain error for either one of the reason : either you are trying to use a negative number inside log function or a zero value.

I prefer creating Visual Effects via Storyboard - no code used for creating or maintaining UI Elements. It gives me full landscape support, too. I have made a little demo of using UIVisualEffects with Blur and also Vibrancy.

Demo on Github

In your component i.e angular JS code:

function getData(){
    window.location.href = 'http://localhost:1036/api/Employee/GetExcelData';
}

An enum is kind of like a typedef for the int type (kind of).

So the type you've defined there has 12 possible values, however a single variable only ever has one of those values.

Think of it this way, when you define an enum you're basically defining another way to assign an int value.

In the example you've provided, january is another way of saying 0, feb is another way of saying 1, etc until december is another way of saying 11.

Try changing the second parameter in the SaveAs call to Excel.XlFileFormat.xlWorkbookDefault.

When I did that, I generated an xlsx file that I was able to successfully open. (Before making the change, I could produce an xlsx file, but I was unable to open it.)

Also, I'm not sure if it matters or not, but I'm using the Excel 12.0 object library.

Edit: isaykatsman has a pytorch PR to add a model.summary() that is exactly like keras https://github.com/pytorch/pytorch/pull/3043/files

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

For SQL Developer

You have to execute it manually

SET SERVEROUTPUT ON 

After that if you execute any procedure with DBMS_OUTPUT.PUT_LINE('info'); or directly .

This will print the line

And please don't try to add this

 SET SERVEROUTPUT ON

inside the definition of function and procedure, it will not compile and will not work.

If you want to inspect html, css or maybe you need js console in your mobile browser . You can use excelent tool eruda Using it you have the same Developer Tools on your mobile browser like in your desctop device. Dont forget to upvote :) Here is a link https://github.com/liriliri/eruda

Let's say your table has two other columns: foo and bar

INSERT INTO Table (foo, bar, Event_ID)
SELECT foo, bar, "155"
  FROM Table
 WHERE Event_ID = "120"

You can use async/await for this. I would explain more, but there's nothing really to it. It's just a regular for loop but I added the await keyword before the construction of your Promise

What I like about this is your Promise can resolve a normal value instead of having a side effect like your code (or other answers here) include. This gives you powers like in The Legend of Zelda: A Link to the Past where you can affect things in both the Light World and the Dark World – ie, you can easily work with data before/after the Promised data is available without having to resort to deeply nested functions, other unwieldy control structures, or stupid IIFEs.

// where DarkWorld is in the scary, unknown future
// where LightWorld is the world we saved from Ganondorf
LightWorld ... await DarkWorld

So here's what that will look like ...

const someProcedure = async n =>_x000D_
  {_x000D_
    for (let i = 0; i < n; i++) {_x000D_
      const t = Math.random() * 1000_x000D_
      const x = await new Promise(r => setTimeout(r, t, i))_x000D_
      console.log (i, x)_x000D_
    }_x000D_
    return 'done'_x000D_
  }_x000D_
_x000D_
someProcedure(10).then(x => console.log(x)) // => Promise_x000D_
// 0 0_x000D_
// 1 1_x000D_
// 2 2_x000D_
// 3 3_x000D_
// 4 4_x000D_
// 5 5_x000D_
// 6 6_x000D_
// 7 7_x000D_
// 8 8_x000D_
// 9 9_x000D_
// done

See how we don't have to deal with that bothersome .then call within our procedure? And async keyword will automatically ensure that a Promise is returned, so we can chain a .then call on the returned value. This sets us up for great success: run the sequence of n Promises, then do something important – like display a success/error message.

I hope this helps

1- The first way is define an interface

public interface OnMessage{
    void sendMessage(int fragmentId, String message);
}

public interface OnReceive{
    void onReceive(String message);
}

2- In you activity implement OnMessage interface

public class MyActivity implements OnMessage {
   ...
   @Override
   public void sendMessage(int fragmentId, String message){
       Fragment fragment = getSupportFragmentManager().findFragmentById(fragmentId);
       ((OnReceive) fragment).sendMessage();
   }
}

3- In your fragment implement OnReceive interface

public class MyFragment implements OnReceive{
    ...
    @Override
    public void onReceive(String message){
        myTextView.setText("Received message:" + message);
    }
}

This is the boilerplate version of handling message passing between fragments.

Another way of handing data passage between fragments are by using an event bus.

1- Register/unregister to an event bus

@Override
public void onStart() {
    super.onStart();
    EventBus.getDefault().register(this);
}

@Override
public void onStop() {
    EventBus.getDefault().unregister(this);
    super.onStop();
}

2- Define an event class

public class Message{
    public final String message;

    public Message(String message){
        this.message = message;
    }
}

3- Post this event in anywhere in your application

EventBus.getDefault().post(new Message("hello world"));

4- Subscribe to that event to receive it in your Fragment

@Subscribe(threadMode = ThreadMode.MAIN)
public void onMessage(Message event){
    mytextview.setText(event.message);
}

For more details, use cases, and an example project about the event bus pattern.

To bypass this in PHPMyAdmin or with MySQL, first remove the foreign key constraint before renaming the attribute.

(For PHPMyAdmin users: To remove FK constrains in PHPMyAdmin, select the attribute then click "relation view" next to "print view" in the toolbar below the table structure)

I use this extension method:

public static IQueryable<T> Page<T, TResult>(this IQueryable<T> obj, int page, int pageSize, System.Linq.Expressions.Expression<Func<T, TResult>> keySelector, bool asc, out int rowsCount)
{
    rowsCount = obj.Count();
    int innerRows = rowsCount - (page * pageSize);
    if (innerRows < 0)
    {
        innerRows = 0;
    }
    if (asc)
        return obj.OrderByDescending(keySelector).Take(innerRows).OrderBy(keySelector).Take(pageSize).AsQueryable();
    else
        return obj.OrderBy(keySelector).Take(innerRows).OrderByDescending(keySelector).Take(pageSize).AsQueryable();
}

public IEnumerable<Data> GetAll(int RowIndex, int PageSize, string SortExpression)
{
    int totalRows;
    int pageIndex = RowIndex / PageSize;

    List<Data> data= new List<Data>();
    IEnumerable<Data> dataPage;

    bool asc = !SortExpression.Contains("DESC");
    switch (SortExpression.Split(' ')[0])
    {
        case "ColumnName":
            dataPage = DataContext.Data.Page(pageIndex, PageSize, p => p.ColumnName, asc, out totalRows);
            break;
        default:
            dataPage = DataContext.vwClientDetails1s.Page(pageIndex, PageSize, p => p.IdColumn, asc, out totalRows);
            break;
    }

    foreach (var d in dataPage)
    {
        clients.Add(d);
    }

    return data;
}
public int CountAll()
{
    return DataContext.Data.Count();
}

We had this exact problem with fontawesome-webfont.woff2 throwing a 406 error on a shared host (Cpanel). I was working on the elusive "cookie-less domain" for a Wordpress Multisite project and my "www.domain.tld" pages would have the following error (3 times) in Chrome:

Font from origin 'http://static.domain.tld' has been blocked from loading by Cross-Origin Resource Sharing policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://www.domain.tld' is therefore not allowed access.

and in Firefox, a little more detail:

I got to QWANT-ing around (QWANT.com = fantastic) and found this SO post:

An hour in chat with different Shared Host support staff (one didn't even know about F12 in a browser...) then waiting for a response to the ticket that got cut after no joy while playing with mod_security. I tried to cobble the code for the .htaccess file together from the post in the meantime, and got this to work to remedy the 406 errors, flawlessly:

    <IfModule mod_headers.c>
    <IfModule mod_rewrite.c>
        SetEnvIf Origin "http(s)?://(.+\.)?domain\.tld(:\d{1,5})?$" CORS=$0
        Header set Access-Control-Allow-Origin "%{CORS}e" env=CORS
        Header merge  Vary "Origin"
    </IfModule>
    </IfModule>

I added that to the top of my .htaccess at the site root and now I have a new Uncle named Bob. (***of course change the domain.tld parts to whatever your domain that you are working with is...)

My FAVORITE part of this post though is the ability to RegEx OR (|) multiple sites into this CORS "hack" by doing:

To allow Multiple sites:

SetEnvIf Origin "http(s)?://(.+\.)?(othersite\.com|mywebsite\.com)(:\d{1,5})?$" CORS=$0

This fix honestly kind of blew my mind because I've ran into this issue before, working with Dev's at Fortune 500 companies that are MILES above my knowledgebase of Apache and couldn't solve problems like this without getting IT to tweak on Apache settings.

This is kind of the magic bullet to fix all those CDN issues with cookie-less (or near cookie-less if you use CloudFlare...) domains to reduce the amount of unnecessary web traffic from cookies that get sent with every image request only to be ditched like a bad blind date by the server.

Super Secure, Super Elegant. Love it: You don't have to open up your servers bandwidth to resource thieves / hot-link-er types.

If you only want to add Datapoints above the bars, you could easily do it with:

 for i in range(len(frequencies)): # your number of bars
    plt.text(x = x_values[i]-0.25, #takes your x values as horizontal positioning argument 
    y = y_values[i]+1, #takes your y values as vertical positioning argument 
    s = data_labels[i], # the labels you want to add to the data
    size = 9) # font size of datalabels

I like Roko's answer, and added a few lines to it so that you get a triangle that points right when the element is hidden, and down when it is displayed:

.collapse { font-weight: bold; display: inline-block; }
.collapse + input:after { content: " \25b6"; display: inline-block; }
.collapse + input:checked:after { content: " \25bc"; display: inline-block; }
.collapse + input { display: inline-block; -webkit-appearance: none; -o-appearance:none; -moz-appearance:none;  }
.collapse + input + * { display: none; }
.collapse + input:checked + * { display: block; }

IEEE 754 defines 1.0 / 0.0 as Infinity and -1.0 / 0.0 as -Infinity and 0.0 / 0.0 as NaN.

By the way, floating point values also have -0.0 and so 1.0/ -0.0 is -Infinity.

Integer arithmetic doesn't have any of these values and throws an Exception instead.

To check for all possible values (e.g. NaN, 0.0, -0.0) which could produce a non finite number you can do the following.

if (Math.abs(tab[i] = 1 / tab[i]) < Double.POSITIVE_INFINITY)
   throw new ArithmeticException("Not finite");

You can also use ng-pattern ,[7-9] = > mobile number must start with 7 or 8 or 9 ,[0-9] = mobile number accepts digits ,{9} mobile number should be 10 digits.

function form($scope){_x000D_
    $scope.onSubmit = function(){_x000D_
        alert("form submitted");_x000D_
    }_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.5/angular.min.js"></script>_x000D_
<div ng-app ng-controller="form">_x000D_
<form name="myForm" ng-submit="onSubmit()">_x000D_
    <input type="number" ng-model="mobile_number" name="mobile_number" ng-pattern="/^[7-9][0-9]{9}$/" required>_x000D_
    <span ng-show="myForm.mobile_number.$error.pattern">Please enter valid number!</span>_x000D_
    <input type="submit" value="submit"/>_x000D_
</form>_x000D_
</div>

Your example does work. Here's a simplified version.

package main

import "fmt"

func weird(i int) interface{} {
    if i < 0 {
        return "negative"
    }
    return i
}

func main() {
    var i = 42
    if w, ok := weird(7).(int); ok {
        i += w
    }
    if w, ok := weird(-100).(int); ok {
        i += w
    }
    fmt.Println("i =", i)
}

Output:
i = 49

You can use CertMgr to add a certificate as a trusted publisher or if it is self-signed, as a root certificate

CertMgr.exe /add CertificateFileName.cer /s /r localMachine root

The problem is that your ui property uses a forward declaration of class Ui::MainWindowClass, hence the "incomplete type" error.

Including the header file in which this class is declared will fix the problem.

EDIT

Based on your comment, the following code:

namespace Ui
{
    class MainWindowClass;
}

does NOT declare a class. It's a forward declaration, meaning that the class will exist at some point, at link time.
Basically, it just tells the compiler that the type will exist, and that it shouldn't warn about it.

But the class has to be defined somewhere.

Note this can only work if you have a pointer to such a type.
You can't have a statically allocated instance of an incomplete type.

So either you actually want an incomplete type, and then you should declare your ui member as a pointer:

namespace Ui
{
    // Forward declaration - Class will have to exist at link time
    class MainWindowClass;
}

class MainWindow : public QMainWindow
{
    private:

        // Member needs to be a pointer, as it's an incomplete type
        Ui::MainWindowClass * ui;
};

Or you want a statically allocated instance of Ui::MainWindowClass, and then it needs to be declared. You can do it in another header file (usually, there's one header file per class).
But simply changing the code to:

namespace Ui
{
    // Real class declaration - May/Should be in a specific header file
    class MainWindowClass
    {};
}


class MainWindow : public QMainWindow
{
    private:

        // Member can be statically allocated, as the type is complete
        Ui::MainWindowClass ui;
};

will also work.

Note the difference between the two declarations. First uses a forward declaration, while the second one actually declares the class (here with no properties nor methods).

If you have no opportunity to change name="submit" you can also submit form this way:

function submitForm(form) {
    const submitFormFunction = Object.getPrototypeOf(form).submit;
    submitFormFunction.call(form);
}

I'd go with @sandeep's display: table-cell answer if you don't care about IE7.

Otherwise, here's an alternative, with one downside: the "right" div has to come first in the HTML.

See: http://jsfiddle.net/thirtydot/qLTMf/
and exactly the same, but with the "right div" removed: http://jsfiddle.net/thirtydot/qLTMf/1/

#parent {
    overflow: hidden;
    border: 1px solid red
}
.right {
    float: right;
    width: 100px;
    height: 100px;
    background: #888;
}
.left {
    overflow: hidden;
    height: 100px;
    background: #ccc
}
<div id="parent">
    <div class="right">right</div>
    <div class="left">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nullam semper porta sem, at ultrices ante interdum at. Donec condimentum euismod consequat. Ut viverra lorem pretium nisi malesuada a vehicula urna aliquet. Proin at ante nec neque commodo bibendum. Cras bibendum egestas lacus, nec ullamcorper augue varius eget.</div>

The simulators are located under:

~/Library/Developer/CoreSimulator/

Here, they are listed as directories with UUID names. Use sort by 'Date modified' to find the latest one. Inside navigate to:

/data/Containers/Data/Application/

Here you will get a list of all the applications on that device. You can again sort this to get the latest app.

NOTE: Xcode changes the directory name every time you run the app, so don't rely on making alias/short cuts on desktop.

The easiest way is to use the app here, which does everything automatically.

There aren't a lot of "Best Practices" yet. Those of us that are using inline-styles, for React components, are still very much experimenting.

There are a number of approaches that vary wildly: React inline-style lib comparison chart

All or nothing?

What we refer to as "style" actually includes quite a few concepts:

• Layout — how an element/component looks in relationship to others
• Appearance — the characteristics of an element/component
• Behavior and state — how an element/component looks in a given state

Start with state-styles

React is already managing the state of your components, this makes styles of state and behavior a natural fit for colocation with your component logic.

Instead of building components to render with conditional state-classes, consider adding state-styles directly:

// Typical component with state-classes
<li 
 className={classnames({ 'todo-list__item': true, 'is-complete': item.complete })} />


// Using inline-styles for state
<li className='todo-list__item'
 style={(item.complete) ? styles.complete : {}} />

Note that we're using a class to style appearance but no longer using any .is- prefixed class for state and behavior.

We can use Object.assign (ES6) or _.extend (underscore/lodash) to add support for multiple states:

// Supporting multiple-states with inline-styles
<li 'todo-list__item'
 style={Object.assign({}, item.complete && styles.complete, item.due && styles.due )}>

Customization and reusability

Now that we're using Object.assign it becomes very simple to make our component reusable with different styles. If we want to override the default styles, we can do so at the call-site with props, like so: <TodoItem dueStyle={ fontWeight: "bold" } />. Implemented like this:

<li 'todo-list__item'
 style={Object.assign({},
         item.due && styles.due,
         item.due && this.props.dueStyles)}>

Layout

Personally, I don't see compelling reason to inline layout styles. There are a number of great CSS layout systems out there. I'd just use one.

That said, don't add layout styles directly to your component. Wrap your components with layout components. Here's an example.

// This couples your component to the layout system
// It reduces the reusability of your component
<UserBadge
 className="col-xs-12 col-sm-6 col-md-8"
 firstName="Michael"
 lastName="Chan" />

// This is much easier to maintain and change
<div class="col-xs-12 col-sm-6 col-md-8">
  <UserBadge
   firstName="Michael"
   lastName="Chan" />
</div>

For layout support, I often try to design components to be 100% width and height.

Appearance

This is the most contentious area of the "inline-style" debate. Ultimately, it's up to the component your designing and the comfort of your team with JavaScript.

One thing is certain, you'll need the assistance of a library. Browser-states (:hover, :focus), and media-queries are painful in raw React.

I like Radium because the syntax for those hard parts is designed to model that of SASS.

Code organization

Often you'll see a style object outside of the module. For a todo-list component, it might look something like this:

var styles = {
  root: {
    display: "block"
  },
  item: {
    color: "black"

    complete: {
      textDecoration: "line-through"
    },

    due: {
      color: "red"
    }
  },
}

getter functions

Adding a bunch of style logic to your template can get a little messy (as seen above). I like to create getter functions to compute styles:

React.createClass({
  getStyles: function () {
    return Object.assign(
      {},
      item.props.complete && styles.complete,
      item.props.due && styles.due,
      item.props.due && this.props.dueStyles
    );
  },

  render: function () {
    return <li style={this.getStyles()}>{this.props.item}</li>
  }
});

Further watching

I discussed all of these in more detail at React Europe earlier this year: Inline Styles and when it's best to 'just use CSS'.

I'm happy to help as you make new discoveries along the way :) Hit me up -> @chantastic

More recently I am testing this CSS source for the Bootstrap carousel

The height set to 380 should be set equal to the biggest/tallest image being displayed...

Please Vote up/down this answer based on usability testing with the following CSS thanks.

/* CUSTOMIZE THE CAROUSEL
-------------------------------------------------- */

/* Carousel base class */
.carousel {
  max-height: 100%;
  max-height: 380px;
  margin-bottom: 60px;
  height:auto;
}
/* Since positioning the image, we need to help out the caption */
.carousel-caption {
  z-index: 10;
    background: rgba(0, 0, 0, 0.45);
}

/* Declare heights because of positioning of img element */
.carousel .item {
  max-height: 100%;
  max-height: 380px;
  background-color: #777;
}
.carousel-inner > .item > img {
 /*  position: absolute;*/
  top: 0;
  left: 0;
  min-width: 40%;
  max-width: 100%;
  max-height: 380px;
  width: auto;
  margin-right:auto;
  margin-left:auto;
  height:auto;

}

You can do a variety of things. What I would do is this.

Create an array on scope that will be your data structure for the phone numbers.

$scope.telephone = '';
$scope.numbers = [];

Then in your html I would have this

<input type="text" ng-model="telephone">
<button ng-click="submitNumber()">Submit</button>

Then when your user clicks submit, run submitNumber(), which pushes the new telephone number into the numbers array.

$scope.submitNumber = function(){
  $scope.numbers.push($scope.telephone);
}

Use selectionStart/selectionEnd properties of the input element (works for <textarea> as well)

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

The neatest solution I've found is to create your own JsonResult that extends the original implementation and allows you to specify a HttpStatusCode:

public class JsonHttpStatusResult : JsonResult
{
    private readonly HttpStatusCode _httpStatus;

    public JsonHttpStatusResult(object data, HttpStatusCode httpStatus)
    {
        Data = data;
        _httpStatus = httpStatus;
    }

    public override void ExecuteResult(ControllerContext context)
    {
        context.RequestContext.HttpContext.Response.StatusCode = (int)_httpStatus;
        base.ExecuteResult(context);
    }
}

You can then use this in your controller action like so:

if(thereWereErrors)
{
    var errorModel = new { error = "There was an error" };
    return new JsonHttpStatusResult(errorModel, HttpStatusCode.InternalServerError);
}

element.GetAttribute("value");

Eventhough if you don't see the "value" attribute in html dom, you will get the field value displayed on the GUI.

Give the height of the div .youtube-thumb the height of the image. That should set the problem in Firefox browser.

.youtube-thumb{ height: 106px }

Use a generic Last<T>. That will work with ANY IEnumerable, including string.

public static IEnumerable<T> Last<T>(this IEnumerable<T> enumerable, int nLastElements)
{
    int count = Math.Min(enumerable.Count(), nLastElements);
    for (int i = enumerable.Count() - count; i < enumerable.Count(); i++)
    {
        yield return enumerable.ElementAt(i);
    }
}

And a specific one for string:

public static string Right(this string str, int nLastElements)
{
    return new string(str.Last(nLastElements).ToArray());
}

Another one in Python, it's not in place as @cdiggins's, but I think it's easier to understand

def permute(num):
    if len(num) == 2:
        # get the permutations of the last 2 numbers by swapping them
        yield num
        num[0], num[1] = num[1], num[0]
        yield num
    else:
        for i in range(0, len(num)):
            # fix the first number and get the permutations of the rest of numbers
            for perm in permute(num[0:i] + num[i+1:len(num)]):
                yield [num[i]] + perm

for p in permute([1, 2, 3, 4]):
    print p

You need a parameterless constructor to be able to create an instance of your class. Your current constructor requires two input string parameters.

Normally C++ implies having such a constructor (=default parameterless constructor) if there is no other constructor declared. By declaring your first constructor with two parameters you overwrite this default behaviour and now you have to declare this constructor explicitly.

Here is the working code:

#include <iostream> 
#include <string>  // <-- you need this if you want to use string type

using namespace std; 

class name { 
  public: 
    string first; 
    string last; 

  name(string a, string b){ 
    first = a; 
    last = b; 

  }

  name ()  // <-- this is your explicit parameterless constructor
  {}

}; 

int main (int argc, const char * argv[]) 
{ 

  const int howManyNames = 3; 

  name someName[howManyNames]; 

  return 0; 
}

(BTW, you need to include to make the code compilable.)

An alternative way is to initialize your instances explicitly on declaration

  name someName[howManyNames] = { {"Ivan", "The Terrible"}, {"Catherine", "The Great"} };

Just add @Transactional annotation on top of your test:

@RunWith(SpringJUnit4ClassRunner.class)  
@ContextConfiguration(locations = {"testContext.xml"})
@Transactional
public class StudentSystemTest {

By default Spring will start a new transaction surrounding your test method and @Before/@After callbacks, rolling back at the end. It works by default, it's enough to have some transaction manager in the context.

From: 10.3.5.4 Transaction management (bold mine):

In the TestContext framework, transactions are managed by the TransactionalTestExecutionListener. Note that TransactionalTestExecutionListener is configured by default, even if you do not explicitly declare @TestExecutionListeners on your test class. To enable support for transactions, however, you must provide a PlatformTransactionManager bean in the application context loaded by @ContextConfiguration semantics. In addition, you must declare @Transactional either at the class or method level for your tests.

My simple way to solve this:

Create a new Python file like: json_to_csv.py

Add this code:

import csv, json, sys
#if you are not using utf-8 files, remove the next line
sys.setdefaultencoding("UTF-8")
#check if you pass the input file and output file
if sys.argv[1] is not None and sys.argv[2] is not None:

    fileInput = sys.argv[1]
    fileOutput = sys.argv[2]

    inputFile = open(fileInput)
    outputFile = open(fileOutput, 'w')
    data = json.load(inputFile)
    inputFile.close()

    output = csv.writer(outputFile)

    output.writerow(data[0].keys())  # header row

    for row in data:
        output.writerow(row.values())

After add this code, save the file and run at the terminal:

python json_to_csv.py input.txt output.csv

I hope this help you.

SEEYA!

You can always try this:

/home/user/anaconda3/bin/pip install -r requirements.txt

This simply uses the pip installed in the conda environment. If pip is not preinstalled in your environment you can always run the following command

conda install pip

If you need a menu to refresh a webview inside a specific Fragment, you can use:

Fragment:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    // TODO Add your menu entries here
    inflater.inflate(R.menu.menu, menu);
    super.onCreateOptionsMenu(menu, inflater);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.exit:
        System.exit(1);
        break;

    case R.id.refresh:
        webView.reload();
        break;
    }
    return true;

}

menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/exit" android:title="Exit" android:icon="@drawable/ic_action_cancel" />
    <item android:id="@+id/refresh" android:title="Refresh" android:icon="@drawable/ic_action_refresh" />
</menu>

For those who are still getting blank response with $request->getContent(), you can use:

$request->all()

e.g:

public function foo(Request $request){
   $bodyContent = $request->all();
}

or you can add the AutoCompleteBox into the toolbox by clicking on it and then Choose Items, go to WPF Components, type in the filter AutoCompleteBox, which is on the System.Windows.Controls namespace and the just drag into your xaml file. This is way much easier than doing these other stuff, since the AutoCompleteBox is a native control.

<sup>Note:
* This answer probably goes deeper than the use case warrants, and find 2>/dev/null may be good enough in many situations. It may still be of interest for a cross-platform perspective and for its discussion of some advanced shell techniques in the interest of finding a solution that is as robust as possible, even though the cases guarded against may be largely hypothetical.
* If your system is configured to show localized error messages, prefix the find calls below with LC_ALL=C (LC_ALL=C find ...) to ensure that English messages are reported, so that grep -v 'Permission denied' works as intended. Invariably, however, any error messages that do get displayed will then be in English as well.</sup>

If your shell is bash or zsh, there's a solution that is robust while being reasonably simple, using only POSIX-compliant find features; while bash itself is not part of POSIX, most modern Unix platforms come with it, making this solution widely portable:

find . > files_and_folders 2> >(grep -v 'Permission denied' >&2)

Note: There's a small chance that some of grep's output may arrive after find completes, because the overall command doesn't wait for the command inside >(...) to finish. In bash, you can prevent this by appending | cat to the command.

• >(...) is a (rarely used) output process substitution that allows redirecting output (in this case, stderr output (2>) to the stdin of the command inside >(...).
  In addition to bash and zsh, ksh supports them as well in principle, but trying to combine them with redirection from stderr, as is done here (2> >(...)), appears to be silently ignored (in ksh 93u+).

  • grep -v 'Permission denied' filters out (-v) all lines (from the find command's stderr stream) that contain the phrase Permission denied and outputs the remaining lines to stderr (>&2).

This approach is:

• robust: grep is only applied to error messages (and not to a combination of file paths and error messages, potentially leading to false positives), and error messages other than permission-denied ones are passed through, to stderr.

• side-effect free: find's exit code is preserved: the inability to access at least one of the filesystem items encountered results in exit code 1 (although that won't tell you whether errors other than permission-denied ones occurred (too)).

POSIX-compliant solutions:

Fully POSIX-compliant solutions either have limitations or require additional work.

If find's output is to be captured in a file anyway (or suppressed altogether), then the pipeline-based solution from Jonathan Leffler's answer is simple, robust, and POSIX-compliant:

find . 2>&1 >files_and_folders | grep -v 'Permission denied' >&2

Note that the order of the redirections matters: 2>&1 must come first.

Capturing stdout output in a file up front allows 2>&1 to send only error messages through the pipeline, which grep can then unambiguously operate on.

The only downside is that the overall exit code will be the grep command's, not find's, which in this case means: if there are no errors at all or only permission-denied errors, the exit code will be 1 (signaling failure), otherwise (errors other than permission-denied ones) 0 - which is the opposite of the intent.
That said, find's exit code is rarely used anyway, as it often conveys little information beyond fundamental failure such as passing a non-existent path.
However, the specific case of even only some of the input paths being inaccessible due to lack of permissions is reflected in find's exit code (in both GNU and BSD find): if a permissions-denied error occurs for any of the files processed, the exit code is set to 1.

The following variation addresses that:

find . 2>&1 >files_and_folders | { grep -v 'Permission denied' >&2; [ $? -eq 1 ]; }

Now, the exit code indicates whether any errors other than Permission denied occurred: 1 if so, 0 otherwise.
In other words: the exit code now reflects the true intent of the command: success (0) is reported, if no errors at all or only permission-denied errors occurred.
This is arguably even better than just passing find's exit code through, as in the solution at the top.

gniourf_gniourf in the comments proposes a (still POSIX-compliant) generalization of this solution using sophisticated redirections, which works even with the default behavior of printing the file paths to stdout:

{ find . 3>&2 2>&1 1>&3 | grep -v 'Permission denied' >&3; } 3>&2 2>&1

In short: Custom file descriptor 3 is used to temporarily swap stdout (1) and stderr (2), so that error messages alone can be piped to grep via stdout.

Without these redirections, both data (file paths) and error messages would be piped to grep via stdout, and grep would then not be able to distinguish between error message Permission denied and a (hypothetical) file whose name happens to contain the phrase Permission denied.

As in the first solution, however, the the exit code reported will be grep's, not find's, but the same fix as above can be applied.

Notes on the existing answers:

• There are several points to note about Michael Brux's answer, find . ! -readable -prune -o -print:

  • It requires GNU find; notably, it won't work on macOS. Of course, if you only ever need the command to work with GNU find, this won't be a problem for you.

  • Some Permission denied errors may still surface: find ! -readable -prune reports such errors for the child items of directories for which the current user does have r permission, but lacks x (executable) permission. The reason is that because the directory itself is readable, -prune is not executed, and the attempt to descend into that directory then triggers the error messages. That said, the typical case is for the r permission to be missing.

  • Note: The following point is a matter of philosophy and/or specific use case, and you may decide it is not relevant to you and that the command fits your needs well, especially if simply printing the paths is all you do:

    • If you conceptualize the filtering of the permission-denied error messages a separate task that you want to be able to apply to any find command, then the opposite approach of proactively preventing permission-denied errors requires introducing "noise" into the find command, which also introduces complexity and logical pitfalls.
    • For instance, the most up-voted comment on Michael's answer (as of this writing) attempts to show how to extend the command by including a -name filter, as follows:
      find . ! -readable -prune -o -name '*.txt'
      This, however, does not work as intended, because the trailing -print action is required (an explanation can be found in this answer). Such subtleties can introduce bugs.

• The first solution in Jonathan Leffler's answer, find . 2>/dev/null > files_and_folders, as he himself states, blindly silences all error messages (and the workaround is cumbersome and not fully robust, as he also explains). Pragmatically speaking, however, it is the simplest solution, as you may be content to assume that any and all errors would be permission-related.

• mist's answer, sudo find . > files_and_folders, is concise and pragmatic, but ill-advised for anything other than merely printing filenames, for security reasons: because you're running as the root user, "you risk having your whole system being messed up by a bug in find or a malicious version, or an incorrect invocation which writes something unexpectedly, which could not happen if you ran this with normal privileges" (from a comment on mist's answer by tripleee).

• The 2nd solution in viraptor's answer, find . 2>&1 | grep -v 'Permission denied' > some_file runs the risk of false positives (due to sending a mix of stdout and stderr through the pipeline), and, potentially, instead of reporting non-permission-denied errors via stderr, captures them alongside the output paths in the output file.

I find it's a lot easier (than accepted answer) to create a local subdomain by project and tell Apache to serve multiple sites by name.

For example, let's say you created a project under c:/wamp64/www/sites/mysite, to be able to access it at http://mysite.localhost you simply need to do the following:

1. Tell your machine to answer to different names Add 127.0.0.1 mysite.localhost to C:\windows\system32\drivers\etc\hosts

2. Flush your DNS cache Open a Command Prompt as administrator and type net stop dnscache, then net start dnscache.

3. Tell Apache where to look Click on Wamp's icon in tray, go to Apache -> httpd.conf, and add this at the end:

# Tells Apache to identify which site by name
NameVirtualHost *:80
# Tells Apache to serve the default WAMP Server page to "localhost"
<VirtualHost 127.0.0.1>
ServerName localhost
DocumentRoot "C:/wamp/www"
</VirtualHost> 
# Tells Apache to serve Client 1's pages to "client1.localhost"
# Duplicate and modify this block to add another client
<VirtualHost 127.0.0.1>
# The name to respond to
ServerName client1.localhost
# Folder where the files live
DocumentRoot "C:/wamp64/www/sites/mysite"
# A few helpful settings...
<Directory "C:/wamp64/www/sites/mysite">
allow from all
order allow,deny
# Enables .htaccess files for this site
AllowOverride All
</Directory>
# Apache will look for these two files, in this order, if no file is specified in the URL
DirectoryIndex index.html index.php
</VirtualHost> 

(source)

4. Restart Apache Click on Wamp's icon in tray, select "restart"

5. Define a base url Go to your project folder, add <base href="http://mysite.localhost" /> to your <head> section to prevent /links to server root from being broken.

Personally, I inject this html code dynamically into my template using PHP (something like $site_root = (IS_LOCALHOST) ? '<base href="http://mysite.localhost" />' : null;) so I don't have to bother removing that once on production.

You can also use a call to SCOPE_IDENTITY in SQL Server.

If you're looking for something lightweight, I'd append a parameter to your action.

[HttpPost]
public ActionResult ShowAllMobileDetails(MobileViewModel MV, string ddlVendor)
{           
    string strDDLValue = ddlVendor; // Of course, this becomes silly.

    return View(MV);
}

What's happening in your code now, is you're passing the first string argument of "ddlVendor" to Html.DropDownList, and that's telling the MVC framework to create a <select> element with a name of "ddlVendor." When the user submits the form client-side, then, it will contain a value to that key.

When MVC tries to parse that request into MV, it's going to look for MobileList and Vendor and not find either, so it's not going to be populated. By adding this parameter, or using FormCollection as another answer has suggested, you're asking MVC to specifically look for a form element with that name, so it should then populate the parameter value with the posted value.

I changed name of my Project's folder and It's worked , i don't know why :)

SHOW TABLE STATUS WHERE Name = 'xxx'

This will give you (among other things) an Engine column, which is what you want.

Your expression works if you add parentheses:

>>> y[(1 < x) & (x < 5)]
array(['o', 'o', 'a'], 
      dtype='|S1')

There are at least two, easy_install and its successor pip.

If you'd like to track only failed logins, you can use the SQL Server Audit feature (available in SQL Server 2008 and above). You will need to add the SQL server instance you want to audit, and check the failed login operation to audit.

Note: tracking failed logins via SQL Server Audit has its disadvantages. For example - it doesn't provide the names of client applications used.

If you want to audit a client application name along with each failed login, you can use an Extended Events session.

To get you started, I recommend reading this article: http://www.sqlshack.com/using-extended-events-review-sql-server-failed-logins/

You can use the below code to center pagination 

.pagination-centered {_x000D_
    text-align: center;_x000D_
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div class="pagination-centered">_x000D_
    <ul class="pagination">_x000D_
      <li class="active"><a href="#">1</a></li>_x000D_
      <li><a href="#">2</a></li>_x000D_
      <li><a href="#">3</a></li>_x000D_
    </ul>_x000D_
</div>

It is unfortunately easy to program in PHP in a way that consumes memory faster than you realise. Copying strings, arrays and objects instead of using references will do it, though PHP 5 is supposed to do this more automatically than in PHP 4. But dealing with your data set in entirety over several steps is also wasteful compared to processing the smallest logical unit at a time. The classic example is working with large resultsets from a database: most programmers fetch the entire resultset into an array and then loop over it one or more times with foreach(). It is much more memory efficient to use a while() loop to fetch and process one row at a time. The same thing applies to processing a file.

It prevents the browser from doing MIME-type sniffing. Most browsers are now respecting this header, including Chrome/Chromium, Edge, IE >= 8.0, Firefox >= 50 and Opera >= 13. See :

https://blogs.msdn.com/b/ie/archive/2008/09/02/ie8-security-part-vi-beta-2-update.aspx?Redirected=true

Sending the new X-Content-Type-Options response header with the value nosniff will prevent Internet Explorer from MIME-sniffing a response away from the declared content-type.

EDIT:

Oh and, that's an HTTP header, not a HTML meta tag option.

You can not perform a cross-database query like SQL Server; PostgreSQL does not support this.

The DbLink extension of PostgreSQL is used to connect one database to another database. You have install and configure DbLink to execute a cross-database query.

I have already created a step-by-step script and example for executing cross database query in PostgreSQL. Please visit this post: PostgreSQL [Video]: Cross Database Queries using the DbLink Extension

The first maximum you would hit is the length of a String which is 2³¹-1 digits. It's much smaller than the maximum of a BigInteger but IMHO it loses much of its value if it can't be printed.

I use the jQuery clueTip plugin for this.

Just to clarify ... You should always use httpS

But you can bypass it adding the exception:

As I was searching for Scala version, all I could find was McDowell's JNA code above. I include my Scala port here, as there currently isn't anywhere more appropriate.

import com.sun.jna.platform.win32._
object jna {
    def getHome: java.io.File = {
        if (!com.sun.jna.Platform.isWindows()) {
            new java.io.File(System.getProperty("user.home"))
        }
        else {
            val pszPath: Array[Char] = new Array[Char](WinDef.MAX_PATH)
            new java.io.File(Shell32.INSTANCE.SHGetSpecialFolderPath(null, pszPath, ShlObj.CSIDL_MYDOCUMENTS, false) match {
                case true => new String(pszPath.takeWhile(c => c != '\0'))
                case _    => System.getProperty("user.home")
            })
        }
    }
}

As with the Java version, you will need to add Java Native Access, including both jar files, to your referenced libraries.

It's nice to see that JNA now makes this much easier than when the original code was posted.

Closure is a feature in JavaScript where a function has access to its own scope variables, access to the outer function variables and access to the global variables.

Closure has access to its outer function scope even after the outer function has returned. This means a closure can remember and access variables and arguments of its outer function even after the function has finished.

The inner function can access the variables defined in its own scope, the outer function’s scope, and the global scope. And the outer function can access the variable defined in its own scope and the global scope.

Example of Closure:

var globalValue = 5;

function functOuter() {
  var outerFunctionValue = 10;

  //Inner function has access to the outer function value
  //and the global variables
  function functInner() {
    var innerFunctionValue = 5;
    alert(globalValue + outerFunctionValue + innerFunctionValue);
  }
  functInner();
}
functOuter();  

Output will be 20 which sum of its inner function own variable, outer function variable and global variable value.

I found that although the shims from answers above worked, they did not match the behaviour of desktop browsers' implementations of btoa() and atob():

const btoa = function(str){ return Buffer.from(str).toString('base64'); }
// returns "4pyT", yet in desktop Chrome would throw an error.
btoa('?');
// returns "fsO1w6bCvA==", yet in desktop Chrome would return "fvXmvA=="
btoa(String.fromCharCode.apply(null, new Uint8Array([0x7e, 0xf5, 0xe6, 0xbc])));

As it turns out, Buffer instances represent/interpret strings encoded in UTF-8 by default. By contrast, in desktop Chrome, you can't even input a string that contains characters outside of the latin1 range into btoa(), as it will throw an exception: Uncaught DOMException: Failed to execute 'btoa' on 'Window': The string to be encoded contains characters outside of the Latin1 range.

Therefore, you need to explicitly set the encoding type to latin1 in order for your Node.js shim to match the encoding type of desktop Chrome:

const btoaLatin1 = function(str) { return Buffer.from(str, 'latin1').toString('base64'); }
const atobLatin1 = function(b64Encoded) {return Buffer.from(b64Encoded, 'base64').toString('latin1');}

const btoaUTF8 = function(str) { return Buffer.from(str, 'utf8').toString('base64'); }
const atobUTF8 = function(b64Encoded) {return Buffer.from(b64Encoded, 'base64').toString('utf8');}

btoaLatin1('?'); // returns "Ew==" (would be preferable for it to throw error because this is undecodable)
atobLatin1(btoa('?')); // returns "\u0019" (END OF MEDIUM)

btoaUTF8('?'); // returns "4pyT"
atobUTF8(btoa('?')); // returns "?"

// returns "fvXmvA==", just like desktop Chrome
btoaLatin1(String.fromCharCode.apply(null, new Uint8Array([0x7e, 0xf5, 0xe6, 0xbc])));
// returns "fsO1w6bCvA=="
btoaUTF8(String.fromCharCode.apply(null, new Uint8Array([0x7e, 0xf5, 0xe6, 0xbc])));

If you are having this problem for a React Native app, in addition to above mentioned steps, make sure you have the local.properties file in the android directory(AppName/android) of your app which points to your 'sdk' directory:

sdk.dir=/PATH_TO_SDK/

main_list=[]
list_1=["a", "b", "c", "d", "e"]
list_2=["a", "f", "c", "m"]

for i in list_2:
    if i not in list_1:
        main_list.append(i)

print(main_list)

output:

['f', 'm']

Remove dir/.../.git

works for me.

You can try the following:

$group = array();

foreach ( $array as $value ) {
    $group[$value['id']][] = $value;
}

var_dump($group);

Output:

array
  96 => 
    array
      0 => 
        array
          'id' => int 96
          'shipping_no' => string '212755-1' (length=8)
          'part_no' => string 'reterty' (length=7)
          'description' => string 'tyrfyt' (length=6)
          'packaging_type' => string 'PC' (length=2)
      1 => 
        array
          'id' => int 96
          'shipping_no' => string '212755-1' (length=8)
          'part_no' => string 'dftgtryh' (length=8)
          'description' => string 'dfhgfyh' (length=7)
          'packaging_type' => string 'PC' (length=2)
  97 => 
    array
      0 => 
        array
          'id' => int 97
          'shipping_no' => string '212755-2' (length=8)
          'part_no' => string 'ZeoDark' (length=7)
          'description' => string 's%c%s%c%s' (length=9)
          'packaging_type' => string 'PC' (length=2)

As an alternative to using -regex option on find, since the question is labeled bash, you can use the brace expansion mechanism:

eval find . -false "-o -name Robert".{jpg,pdf}

Specifically, this is not rounding your result, it's truncating toward zero. So if you divide -3/2, you'll get -1 and not -2. Welcome to integral math! Back before CPUs could do floating point operations or the advent of math co-processors, we did everything with integral math. Even though there were libraries for floating point math, they were too expensive (in CPU instructions) for general purpose, so we used a 16 bit value for the whole portion of a number and another 16 value for the fraction.

EDIT: my answer makes me think of the classic old man saying "when I was your age..."

An APK is just in zip format. You can unzip it like any other .zip file.

You can decompile .dex files using the dexdump tool, which is provided in the Android SDK.

See https://stackoverflow.com/a/7750547/116938 for more dex info.

A small note on try/finally: The finally will always execute unless

• System.exit() is called.
• The JVM crashes.
• The try{} block never ends (e.g. endless loop).

just add onclick handler for anchor tag

onclick="this.parentNode.style.display = 'none'"

or change onclick handler for img tag

onclick="this.parentNode.parentNode.style.display = 'none'"

In classic mode IIS works h ISAPI extensions and ISAPI filters directly. And uses two pipe lines , one for native code and other for managed code. You can simply say that in Classic mode IIS 7.x works just as IIS 6 and you dont get extra benefits out of IIS 7.x features.

In integrated mode IIS and ASP.Net are tightly coupled rather then depending on just two DLLs on Asp.net as in case of classic mode.

You can use the provider-specific ConnectionStringBuilder class (within the appropriate namespace), or System.Data.Common.DbConnectionStringBuilder to abstract the connection string object if you need to. You'd need to know the provider-specific keywords used to designate the information you're looking for, but for a SQL Server example you could do either of these two things:

System.Data.SqlClient.SqlConnectionStringBuilder builder = new System.Data.SqlClient.SqlConnectionStringBuilder(connectionString);

string server = builder.DataSource;
string database = builder.InitialCatalog;

or

System.Data.Common.DbConnectionStringBuilder builder = new System.Data.Common.DbConnectionStringBuilder();

builder.ConnectionString = connectionString;

string server = builder["Data Source"] as string;
string database = builder["Initial Catalog"] as string;

Had a similiar experience, but it was because I had renamed an enum in one of my classes. I exported and re-imported the Classes that had referred to the old enum and the error message disappeared. This suggests it is a caching issue in the VBA environment.

Prints all the rows with NA data:

tmp <- data.frame(c(1,2,3),c(4,NA,5));
tmp[round(which(is.na(tmp))/ncol(tmp)),]

One of the most simple and understandable solution is:

IF COL_LENGTH('Table_Name','Column_Name') IS NULL
 BEGIN
    -- Column Not Exists, implement your logic
 END 
ELSE
 BEGIN
    -- Column Exists, implement your logic
 END

The problem is that you have several columns in the data frame that contain dicts with smaller dicts inside them. Useful Json is often heavily nested. I have been writing small functions that pull the info I want out into a new column. That way I have it in the format that I want to use.

for row in range(len(data)):
    #First I load the dict (one at a time)
    n = data.loc[row,'dict_column']
    #Now I make a new column that pulls out the data that I want.
    data.loc[row,'new_column'] = n.get('key')

If you really want the API you suggested, you could subclass HashMap and keep track of the keys in a List for example. Don't see the point in this really, but it gives you what you want. If you explain the intended use case, maybe we can come up with a better solution.

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

@SuppressWarnings("unchecked")
public class IndexedMap extends HashMap {

    private List<Object> keyIndex;

    public IndexedMap() {
        keyIndex = new ArrayList<Object>();
    }

    /**
     * Returns the key at the specified position in this Map's keyIndex.
     * 
     * @param index
     *            index of the element to return
     * @return the element at the specified position in this list
     * @throws IndexOutOfBoundsException
     *             if the index is out of range (index < 0 || index >= size())
     */
    public Object get(int index) {
        return keyIndex.get(index);
    }

    @Override
    public Object put(Object key, Object value) {

        addKeyToIndex(key);
        return super.put(key, value);
    }

    @Override
    public void putAll(Map source) {

        for (Object key : source.keySet()) {
            addKeyToIndex(key);
        }
        super.putAll(source);
    }

    private void addKeyToIndex(Object key) {

        if (!keyIndex.contains(key)) {
            keyIndex.add(key);
        }
    }

    @Override
    public Object remove(Object key) {

        keyIndex.remove(key);
        return super.remove(key);
    }
}

EDIT: I deliberately did not delve into the generics side of this...

I found another solution for this problem. This looks like another bug in WebKit (or probably Chrome), but it works. All you need to do - is to add a WebKit CSS Mask to the #wrapper element. You can use a single pixel png image and even include it to the CSS to save a HTTP request.

#wrapper {
width: 300px; height: 300px;
border-radius: 100px;
overflow: hidden;
position: absolute; /* this breaks the overflow:hidden in Chrome/Opera */

/* this fixes the overflow:hidden in Chrome */
-webkit-mask-image: url(data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAEAAAABCAIAAACQd1PeAAAAGXRFWHRTb2Z0d2FyZQBBZG9iZSBJbWFnZVJlYWR5ccllPAAAAA5JREFUeNpiYGBgAAgwAAAEAAGbA+oJAAAAAElFTkSuQmCC);
}

#box {
width: 300px; height: 300px;
background-color: #cde;
}?

No, only use semicolons when they're required.

No need to update gradle for making release application in Android studio.If you were eclipse user then it will be so easy for you. If you are new then follow the steps

1: Go to the "Build" at the toolbar section. 2: Choose "Generate Signed APK..." option.

3:fill opened form and go next 4 :if you already have .keystore or .jks then choose that file enter your password and alias name and respective password. 5: Or don't have .keystore or .jks file then click on Create new... button as shown on pic 1 then fill the form.

Above process was to make build manually. If You want android studio to automatically Signing Your App

In Android Studio, you can configure your project to sign your release APK automatically during the build process:

On the project browser, right click on your app and select Open Module Settings. On the Project Structure window, select your app's module under Modules. Click on the Signing tab. Select your keystore file, enter a name for this signing configuration (as you may create more than one), and enter the required information. Figure 4. Create a signing configuration in Android Studio.

Click on the Build Types tab. Select the release build. Under Signing Config, select the signing configuration you just created. Figure 5. Select a signing configuration in Android Studio.

4:Most Important thing that make debuggable=false at gradle.

    buildTypes {
        release {
           minifyEnabled false
          proguardFiles getDefaultProguardFile('proguard-  android.txt'), 'proguard-rules.txt'
        debuggable false

        renderscriptDebuggable false
        zipAlignEnabled true
       }

I prefer putting a curly brace. But sometimes, ternary operator helps.

In stead of :

int x = 0;
if (condition) {
    x = 30;
} else {
    x = 10;
}

One should simply do : int x = condition ? 30 : 20;

Also imagine a case :

if (condition)
    x = 30;
else if (condition1)
    x = 10;
else if (condition2)
    x = 20;

It would be much better if you put the curly brace in.

Had the same problem, while differently from other answers in my case I use ASP.NET to develop the WebAPI server.

I already had Corps allowed and it worked for GET requests. To make POST requests work I needed to add 'AllowAnyHeader()' and 'AllowAnyMethod()' options to the list of Corp options.

Here are essential parts of related functions in Start class look like:

                          {
                              builder
                                  .WithOrigins("http://localhost:4200")
                                  .AllowAnyHeader()
                                  .AllowAnyMethod()
                                  //.AllowCredentials()
                                  ;
                          });
    });

Configure method:

        app.UseCors(MyAllowSpecificOrigins);

2.forward send the request to another servlet (servlet to servlet).

If you have created multiple worktrees with git worktree, you'll need to run git prune before you can delete the branch

Angular 5

html

<input type="file" #inputFile>

<button (click)="reset()">Reset</button>

template

@ViewChild('inputFile') myInputVariable: ElementRef;

reset() {
    this.myInputVariable.nativeElement.value = '';
}

Button is not required. You can reset it after change event, it is just for demonstration

Check into this thread,. However you should be careful as it's documented as "can change upon factory reset". Use at your own risk, and it can be easily changed on a rooted phone. Also it appears as if some manufacturers have had issues with their phones having duplicate numbers thread. Depending on what your trying to do, I probably wouldnt use this as a UID.

Reference article: Show red color border for invalid input fields angualrjs

I used ng-class on all input fields.like below

<input type="text" ng-class="{submitted:newEmployee.submitted}" placeholder="First Name" data-ng-model="model.firstName" id="FirstName" name="FirstName" required/>

when I click on save button I am changing newEmployee.submitted value to true(you can check it in my question). So when I click on save, a class named submitted gets added to all input fields(there are some other classes initially added by angularjs).

So now my input field contains classes like this

class="ng-pristine ng-invalid submitted"

now I am using below css code to show red border on all invalid input fields(after submitting the form)

input.submitted.ng-invalid
{
  border:1px solid #f00;
}

Thank you !!

Update:

We can add the ng-class at the form element instead of applying it to all input elements. So if the form is submitted, a new class(submitted) gets added to the form element. Then we can select all the invalid input fields using the below selector

form.submitted .ng-invalid
{
    border:1px solid #f00;
}

You can use this:

string alpha = "abcdefghijklmnopqrstuvwxyz";
int length = alpha.Length;

for (int i = length - ((length - 1) % 5 + 1); i > 0; i -= 5)
{
    alpha = alpha.Insert(i, "-");
}

Works perfectly with any string. As always, the size doesn't matter. ;)

This is a fix for people who are not using maven. You also need to add standard.jar to your lib folder for the core tag library to work. Works for jstl version 1.1.

<%@taglib prefix="core" uri="http://java.sun.com/jsp/jstl/core"%>

That is not possible. A function that has a non-void return type (even if it's Void) has to return a value. However you could add static methods to Action that allows you to "create" a Action:

interface Action<T, U> {
   U execute(T t);

   public static Action<Void, Void> create(Runnable r) {
       return (t) -> {r.run(); return null;};
   }

   public static <T, U> Action<T, U> create(Action<T, U> action) {
       return action;
   } 
}

That would allow you to write the following:

// create action from Runnable
Action.create(()-> System.out.println("Hello World")).execute(null);
// create normal action
System.out.println(Action.create((Integer i) -> "number: " + i).execute(100));

You can use jQuery UI and do something like this

Html:

<button id="callConfirm">Confirm!</button>

<div id="dialog" title="Confirmation Required">
  Are you sure about this?
</div>?

Javascript:

$("#dialog").dialog({
   autoOpen: false,
   modal: true,
   buttons : {
        "Confirm" : function() {
            alert("You have confirmed!");            
        },
        "Cancel" : function() {
          $(this).dialog("close");
        }
      }
    });

$("#callConfirm").on("click", function(e) {
    e.preventDefault();
    $("#dialog").dialog("open");
});

<div id="calendar"></div>
<script>
$(document).ready(function() {
    var days = [];

    $('#calendar').datepicker({
        dateFormat: 'yymmdd',
        showWeek: true, showOtherMonths: false, selectOtherMonths: false,
        navigationAsDateFormat: true, prevText: 'MM', nextText: 'MM',
        onSelect: function(d) {
            var i = $.inArray(d, days);

            if (i == -1)
                days.push(d);
            else
                days.splice(i, 1);
        },
        beforeShowDay: function(d) {
            return ([true, $.inArray($.datepicker.formatDate('yymmdd', d), days) == -1 ? 'ui-state-free' : 'ui-state-busy']);
        }

#calendar .ui-state-busy a {background:#e6e6e6 !important;}
#calendar .ui-state-free a {background:none !important;}

To get the list of days selected by the calendar in a <form>:

<div id="calendar"></div>
<form method="post">
<input type="submit" name="calendar_get" id="calendar_get" value="Validate" />
</form>

Add this to the <script>:

    $('#calendar_get').click(function() {
        $(this).append('<input type="hidden" name="calendar_days" value="' + days.join(',') + '" />');
    });

Apply implode on the string in $_POST['calendar_days'] and map strtotime to all the formatted dates.

You can't do this using forms the normal way. Instead, you want to use AJAX.

A sample function that will submit the data and alert the page response.

function submitForm() {
    var http = new XMLHttpRequest();
    http.open("POST", "<<whereverTheFormIsGoing>>", true);
    http.setRequestHeader("Content-type","application/x-www-form-urlencoded");
    var params = "search=" + <<get search value>>; // probably use document.getElementById(...).value
    http.send(params);
    http.onload = function() {
        alert(http.responseText);
    }
}

If you are binding like I was:

<%# Container.DataItem.GetType().GetProperty("Property1") != null ? DataBinder.Eval(Container.DataItem, "Property1") : DataBinder.Eval(Container.DataItem, "Property2")  %>

As chars can be represented as Integers (ASCII-Codes), you can simply write:

char c = 0;

The 0 in ASCII-Code is null.

Add a reference to System.Management for your project, then try something like this:

namespace ConsoleApplication1
{
  using System;
  using System.Collections.Generic;
  using System.Management; // need to add System.Management to your project references.

  class Program
  {
    static void Main(string[] args)
    {
      var usbDevices = GetUSBDevices();

      foreach (var usbDevice in usbDevices)
      {
        Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}",
            usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description);
      }

      Console.Read();
    }

    static List<USBDeviceInfo> GetUSBDevices()
    {
      List<USBDeviceInfo> devices = new List<USBDeviceInfo>();

      ManagementObjectCollection collection;
      using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_USBHub"))
        collection = searcher.Get();      

      foreach (var device in collection)
      {
        devices.Add(new USBDeviceInfo(
        (string)device.GetPropertyValue("DeviceID"),
        (string)device.GetPropertyValue("PNPDeviceID"),
        (string)device.GetPropertyValue("Description")
        ));
      }

      collection.Dispose();
      return devices;
    }
  }

  class USBDeviceInfo
  {
    public USBDeviceInfo(string deviceID, string pnpDeviceID, string description)
    {
      this.DeviceID = deviceID;
      this.PnpDeviceID = pnpDeviceID;
      this.Description = description;
    }
    public string DeviceID { get; private set; }
    public string PnpDeviceID { get; private set; }
    public string Description { get; private set; }
  }

Update from 09/2017

It is possible to develop iOS (and Android at the same time) application using React Native + Expo without owning a mac. You will also be able to run your iOS application within iOS Expo app while developing it. (You can even publish it for other people to access, but it will only run within Expo app). Here is page from Expo on how to generate standalone app.

Steps from that page:

One: Install exp by running npm install -g exp

Two: Configure app.json (somewhere along these lines):

{
   "expo": {
    "name": "Your App Name",
    "icon": "./path/to/your/app-icon.png",
    "version": "1.0.0",
    "slug": "your-app-slug",
    "sdkVersion": "17.0.0",
    "ios": {
      "bundleIdentifier": "com.yourcompany.yourappname"
    },
    "android": {
      "package": "com.yourcompany.yourappname"
    }
   }
 }

Three: Start exp packeger with exp start

Four: run exp build:android or exp build:ios.

You will be prompted for some input. For android you can choose 1) Let Expo handle the process! if you don't have keystore (or if you don't know what it is). For iOS you will have to enter your Apple developer credentials. Then you can provide distribution certificate or let expo handle it.

Five: Once in a while you will have to come back and run exp build:status command to check whether your build was complete. If complete you will be provided a direct link to .apk or .ipa file.

The only drawback to this approach is that it won't be as native as writing iOS app in Swift, and you will have to put up with parade of issues you may run into while developing with weakly typed js, npm, and it's dependency-on-particular-version-of-some-other-library issues, and other stuff.

One of the answers in the question referred to by @Z.Bagley gave me the answer. I had to import Renderer2 from @angular/core into my component. Then:

const element = this.renderer.selectRootElement('#input1');

// setTimeout(() => element.focus, 0);
setTimeout(() => element.focus(), 0);

Thank you @MrBlaise for the solution!

The problem is that the 'and' is being treated as an 'or'.

No, the problem is that you are using the XPath != operator and you aren't aware of its "weird" semantics.

Solution:

Just replace the any x != y expressions with a not(x = y) expression.

In your specific case:

Replace:

<xsl:when test="$AccountNumber != '12345' and $Balance != '0'">

with:

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')">

Explanation:

By definition whenever one of the operands of the != operator is a nodeset, then the result of evaluating this operator is true if there is a node in the node-set, whose value isn't equal to the other operand.

So:

 $someNodeSet != $someValue

generally doesn't produce the same result as:

 not($someNodeSet = $someValue)

The latter (by definition) is true exactly when there isn't a node in $someNodeSet whose string value is equal to $someValue.

Lesson to learn:

Never use the != operator, unless you are absolutely sure you know what you are doing.

Let's get one thing out of the way first. The explanation that yield from g is equivalent to for v in g: yield v does not even begin to do justice to what yield from is all about. Because, let's face it, if all yield from does is expand the for loop, then it does not warrant adding yield from to the language and preclude a whole bunch of new features from being implemented in Python 2.x.

What yield from does is it establishes a transparent bidirectional connection between the caller and the sub-generator:

• The connection is "transparent" in the sense that it will propagate everything correctly too, not just the elements being generated (e.g. exceptions are propagated).

• The connection is "bidirectional" in the sense that data can be both sent from and to a generator.

(If we were talking about TCP, yield from g might mean "now temporarily disconnect my client's socket and reconnect it to this other server socket".)

BTW, if you are not sure what sending data to a generator even means, you need to drop everything and read about coroutines first—they're very useful (contrast them with subroutines), but unfortunately lesser-known in Python. Dave Beazley's Curious Course on Coroutines is an excellent start. Read slides 24-33 for a quick primer.

Reading data from a generator using yield from

def reader():
    """A generator that fakes a read from a file, socket, etc."""
    for i in range(4):
        yield '<< %s' % i

def reader_wrapper(g):
    # Manually iterate over data produced by reader
    for v in g:
        yield v

wrap = reader_wrapper(reader())
for i in wrap:
    print(i)

# Result
<< 0
<< 1
<< 2
<< 3

Instead of manually iterating over reader(), we can just yield from it.

def reader_wrapper(g):
    yield from g

That works, and we eliminated one line of code. And probably the intent is a little bit clearer (or not). But nothing life changing.

Sending data to a generator (coroutine) using yield from - Part 1

Now let's do something more interesting. Let's create a coroutine called writer that accepts data sent to it and writes to a socket, fd, etc.

def writer():
    """A coroutine that writes data *sent* to it to fd, socket, etc."""
    while True:
        w = (yield)
        print('>> ', w)

Now the question is, how should the wrapper function handle sending data to the writer, so that any data that is sent to the wrapper is transparently sent to the writer()?

def writer_wrapper(coro):
    # TBD
    pass

w = writer()
wrap = writer_wrapper(w)
wrap.send(None)  # "prime" the coroutine
for i in range(4):
    wrap.send(i)

# Expected result
>>  0
>>  1
>>  2
>>  3

The wrapper needs to accept the data that is sent to it (obviously) and should also handle the StopIteration when the for loop is exhausted. Evidently just doing for x in coro: yield x won't do. Here is a version that works.

def writer_wrapper(coro):
    coro.send(None)  # prime the coro
    while True:
        try:
            x = (yield)  # Capture the value that's sent
            coro.send(x)  # and pass it to the writer
        except StopIteration:
            pass

Or, we could do this.

def writer_wrapper(coro):
    yield from coro

That saves 6 lines of code, make it much much more readable and it just works. Magic!

Sending data to a generator yield from - Part 2 - Exception handling

Let's make it more complicated. What if our writer needs to handle exceptions? Let's say the writer handles a SpamException and it prints *** if it encounters one.

class SpamException(Exception):
    pass

def writer():
    while True:
        try:
            w = (yield)
        except SpamException:
            print('***')
        else:
            print('>> ', w)

What if we don't change writer_wrapper? Does it work? Let's try

# writer_wrapper same as above

w = writer()
wrap = writer_wrapper(w)
wrap.send(None)  # "prime" the coroutine
for i in [0, 1, 2, 'spam', 4]:
    if i == 'spam':
        wrap.throw(SpamException)
    else:
        wrap.send(i)

# Expected Result
>>  0
>>  1
>>  2
***
>>  4

# Actual Result
>>  0
>>  1
>>  2
Traceback (most recent call last):
  ... redacted ...
  File ... in writer_wrapper
    x = (yield)
__main__.SpamException

Um, it's not working because x = (yield) just raises the exception and everything comes to a crashing halt. Let's make it work, but manually handling exceptions and sending them or throwing them into the sub-generator (writer)

def writer_wrapper(coro):
    """Works. Manually catches exceptions and throws them"""
    coro.send(None)  # prime the coro
    while True:
        try:
            try:
                x = (yield)
            except Exception as e:   # This catches the SpamException
                coro.throw(e)
            else:
                coro.send(x)
        except StopIteration:
            pass

This works.

# Result
>>  0
>>  1
>>  2
***
>>  4

But so does this!

def writer_wrapper(coro):
    yield from coro

The yield from transparently handles sending the values or throwing values into the sub-generator.

This still does not cover all the corner cases though. What happens if the outer generator is closed? What about the case when the sub-generator returns a value (yes, in Python 3.3+, generators can return values), how should the return value be propagated? That yield from transparently handles all the corner cases is really impressive. yield from just magically works and handles all those cases.

I personally feel yield from is a poor keyword choice because it does not make the two-way nature apparent. There were other keywords proposed (like delegate but were rejected because adding a new keyword to the language is much more difficult than combining existing ones.

In summary, it's best to think of yield from as a transparent two way channel between the caller and the sub-generator.

The runtime exception classes (RuntimeException and its subclasses) are exempted from compile-time checking, since the compiler cannot establish that run-time exceptions cannot occur. (from JLS).

In the classes that you design you should subclass Exception and throw instances of it to signal any exceptional scenarios. Doing so you will be explicitly signaling the clients of your class that usage of your class might throw exception and they have to take steps to handle those exceptional scenarios.

Below code snippets explain this point:

//Create your own exception class subclassing from Exception
class MyException extends Exception {
    public MyException(final String message) {
        super(message);
    }
}

public class Process {
    public void execute() {
        throw new RuntimeException("Runtime");
    }  
    public void process() throws MyException {
        throw new MyException("Checked");
    }
}

In the above class definition of class Process, the method execute can throw a RuntimeException but the method declaration need not specify that it throws RuntimeException.

The method process throws a checked exception and it should declare that it will throw a checked exception of kind MyException and not doing so will be a compile error.

The above class definition will affect the code that uses Process class as well.

The call new Process().execute() is a valid invocation where as the call of form new Process().process() gives a compile error. This is because the client code should take steps to handle MyException (say call to process() can be enclosed in a try/catch block).

Another way of doing this is using border-image in combination with a linear-gradient.

div {_x000D_
  width: 100px;_x000D_
  height: 75px;_x000D_
  background-color: green;_x000D_
  background-clip: content-box; /* so that the background color is not below the border */_x000D_
  _x000D_
  border-left: 5px solid black;_x000D_
  border-image: linear-gradient(to top, #000 50%, rgba(0,0,0,0) 50%); /* to top - at 50% transparent */_x000D_
  border-image-slice: 1;_x000D_
}

<div></div>

For a better support also add vendor prefixes.

The ToString method on the DateTime struct can take a format parameter:

var dateAsString = DateTime.Now.ToString("yyyy-MM-dd");
// dateAsString = "2011-02-17"

Documentation for standard and custom format strings is available on MSDN.

you can try this one also,

df= df.applymap(lambda s:s.lower() if type(s) == str else s)

In Laravel 5.4 the following worked for me:

return back()->withErrors(['field_name' => ['Your custom message here.']]);

In android studio 3.0 they have introduced android-profiler to help you to understand how your app uses CPU, memory, network, and battery resources.

There is a handy trick that works in some databases for ordering in database order,

SELECT * FROM TableName ORDER BY true

Apparently, this can work in conjunction with any of the other suggestions posted here to leave the results in "order they came out of the database" order, which in some databases, is the order they were last modified in.

I believe this is what you're looking for:

var press = jQuery.Event("keypress");
press.ctrlKey = false;
press.which = 40;
$("whatever").trigger(press);

From here.

best bet is targeting features not devices unless you have to, bootstrap do well and you can extend on their breakpoints, for instance targeting pixel density and larger screens above 1920

When you have a lot of variables that don't need escaping, you can use an autoescape block:

{% autoescape off %}
{{ something }}
{{ something_else }}
<b>{{ something_important }}</b>
{% endautoescape %}

The problem I was having is my css media queries and my IF statement in Jquery clashing. They were both set to 700px but one would think it's hit 700px before the other.

To get around this I created a empty Div right at the top of my HTML(outside my main container)

<div id="max-width"></div>

In css I set this div to display none

 #max-width {
        display: none;
    }

In my JS created a function

var hasSwitched = function () {
    var maxWidth = parseInt($('#max-width').css('max-width'), 10);
    return !isNaN(maxWidth);
};

So in my IF statement instead of saying if (hasSwitched<700) perform the following code, I did the following

if (!hasSwitched()) { Your code

}

else{ your code

}

By doing this CSS tells Jquery when it's hit 700px. So css and jquery are both synchronized... rather than having a couple of pixels difference. Do give this a try peeps it shall definitely not disappoint.

To get this same logic working for IE8 I used the Respond.js plugin(which also definitely works) It lets you use media queries for IE8. Only thing that wasn't supported was the viewport width and viewport height... hence my reason to try get my css and JS working together. Hope this helps you guys

You need to query the data dictionary, specifically the USER_CONS_COLUMNS view to see the table columns and corresponding constraints:

SELECT *
  FROM user_cons_columns
 WHERE table_name = '<your table name>';

FYI, unless you specifically created your table with a lower case name (using double quotes) then the table name will be defaulted to upper case so ensure it is so in your query.

If you then wish to see more information about the constraint itself query the USER_CONSTRAINTS view:

SELECT *
  FROM user_constraints
 WHERE table_name = '<your table name>'
   AND constraint_name = '<your constraint name>';

If the table is held in a schema that is not your default schema then you might need to replace the views with:

all_cons_columns

and

all_constraints

adding to the where clause:

   AND owner = '<schema owner of the table>'

This works fine with me

List<string> myList = new List<string>();
myList.Add(string.Format("{0}|{1}","hello","1") ;


label:myList[0].split('|')[0] 
val:  myList[0].split('|')[1]

FragmentActivity is part of the support library, while Activity is the framework's default class. They are functionally equivalent.

You should always use FragmentActivity and android.support.v4.app.Fragment instead of the platform default Activity and android.app.Fragment classes. Using the platform defaults mean that you are relying on whatever implementation of fragments is used in the device you are running on. These are often multiple years old, and contain bugs that have since been fixed in the support library.

ESP is the current stack pointer, which will change any time a word or address is pushed or popped onto/off off the stack. EBP is a more convenient way for the compiler to keep track of a function's parameters and local variables than using the ESP directly.

Generally (and this may vary from compiler to compiler), all of the arguments to a function being called are pushed onto the stack by the calling function (usually in the reverse order that they're declared in the function prototype, but this varies). Then the function is called, which pushes the return address (EIP) onto the stack.

Upon entry to the function, the old EBP value is pushed onto the stack and EBP is set to the value of ESP. Then the ESP is decremented (because the stack grows downward in memory) to allocate space for the function's local variables and temporaries. From that point on, during the execution of the function, the arguments to the function are located on the stack at positive offsets from EBP (because they were pushed prior to the function call), and the local variables are located at negative offsets from EBP (because they were allocated on the stack after the function entry). That's why the EBP is called the Frame Pointer, because it points to the center of the function call frame.

Upon exit, all the function has to do is set ESP to the value of EBP (which deallocates the local variables from the stack, and exposes the entry EBP on the top of the stack), then pop the old EBP value from the stack, and then the function returns (popping the return address into EIP).

Upon returning back to the calling function, it can then increment ESP in order to remove the function arguments it pushed onto the stack just prior to calling the other function. At this point, the stack is back in the same state it was in prior to invoking the called function.

You should add AutoPostBack="true" to DropDownList1

                <asp:DropDownList ID="ddmanu" runat="server" AutoPostBack="true"
                    DataSourceID="Sql_fur_model_manu"    
                    DataTextField="manufacturer" DataValueField="manufacturer" 
                    onselectedindexchanged="ddmanu_SelectedIndexChanged">
                </asp:DropDownList>

Well, how about:

dynamic jsonObject = new JObject();
jsonObject.Date = DateTime.Now;
jsonObject.Album = "Me Against the world";
jsonObject.Year = 1995;
jsonObject.Artist = "2Pac";

I don't know if this is right or wrong, but I pushed the "old name" of the branch to the "new name" of the branch, then deleted the old branch entirely with the following two lines:

git push origin old_branch:new_branch
git push origin :old_branch

Summary of existing answers plus my own two cents:

1. Basic answer

You can use the header() function to send a new HTTP header, but this must be sent to the browser before any HTML or text (so before the <!DOCTYPE ...> declaration, for example).

header('Location: '.$newURL);

2. Important details

die() or exit()

header("Location: http://example.com/myOtherPage.php");
die();

Why you should use die() or exit(): The Daily WTF

Absolute or relative URL

Since June 2014 both absolute and relative URLs can be used. See RFC 7231 which had replaced the old RFC 2616, where only absolute URLs were allowed.

Status Codes

PHP's "Location"-header still uses the HTTP 302-redirect code, this is a "temporary" redirect and may not be the one you should use. You should consider either 301 (permanent redirect) or 303 (other).

Note: W3C mentions that the 303-header is incompatible with "many pre-HTTP/1.1 user agents. Currently used browsers are all HTTP/1.1 user agents. This is not true for many other user agents like spiders and robots.

3. Documentation

HTTP Headers and the header() function in PHP

• What the PHP manual says
• What Wikipedia says
• What the W3C says

4. Alternatives

You may use the alternative method of http_redirect($url); which needs the PECL package pecl to be installed.

5. Helper Functions

This function doesn't incorporate the 303 status code:

function Redirect($url, $permanent = false)
{
    header('Location: ' . $url, true, $permanent ? 301 : 302);

    exit();
}

Redirect('http://example.com/', false);

This is more flexible:

function redirect($url, $statusCode = 303)
{
   header('Location: ' . $url, true, $statusCode);
   die();
}

6. Workaround

As mentioned header() redirects only work before anything is written out. They usually fail if invoked inmidst HTML output. Then you might use a HTML header workaround (not very professional!) like:

 <meta http-equiv="refresh" content="0;url=finalpage.html">

Or a JavaScript redirect even.

window.location.replace("http://example.com/");

ord() will not work because your end string is two characters long.

Returns the ASCII value of the first character of string.

Watch it break.

From my testing, you need to check that the end string doesn't get "stepped over". The perl-style character incrementation is a cool method, but it is a single-stepping method. For this reason, an inner loop helps it along when necessary. This is actually not a bother, in fact, it is useful because we need to check if the loop(s) should be broken on each single step.

Code: (Demo)

function excelCols($letter,$end,$step=1){  // function doesn't check that $end is "later" than $letter
    if($step==0)return [];  // prevent infinite loop
    do{
        $letters[]=$letter;  // store letter
        for($x=0; $x<$step; ++$x){  // increment in accordance with $step declaration
            if($letter===$end)break(2);  // break if end is "stepped on"
            ++$letter;
        }
    }while(true);
    return $letters;    
}
echo implode(' ',excelCols('A','JJ',4));
echo "\n --- \n";
echo implode(' ',excelCols('A','BB',3));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',1));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',3));

Here is an array-functions approach:

Code: (Demo)

$start='C';
$end='DD';
$step=4;

// generate and store more than we need (this is an obvious method disadvantage)
$result=$array=range('A','Z',1);  // store A - Z as $array and $result
foreach($array as $a){
    foreach($array as $b){
        $result[]="$a$b";  // store double letter combinations
        if(in_array($end,$result)){break(2);}  // stop asap
    }
}
//echo implode(' ',$result),"\n\n";

// slice away from the front of the array
$result=array_slice($result,array_search($start,$result));  // reindex keys
//echo implode(' ',$result),"\n\n";

 // punch out elements that are not "stepped on"
$result=array_filter($result,function($k)use($step){return $k%$step==0;},ARRAY_FILTER_USE_KEY); // use modulo

// result is ready
echo implode(' ',$result);

Output:

Strangely, the answer is to keep adding back the property. I was half expecting a setter method. :S

System.out.println("Before: " + obj.get("DebugLogId")); // original "02352"

obj.addProperty("DebugLogId", "YYY");

System.out.println("After: " + obj.get("DebugLogId")); // now "YYY"

sorry if this is too obvious. Are you sure the webcam is properly seen and detected by OpenCV in other words, do you get an image when you redirect the captured frame to a "highGui" window? For instance like so:

 frame = cvQueryFrame( capture );
 cvNamedWindow( "myWindow", CV_WINDOW_AUTOSIZE );
 cvShowImage( "myWindow", frame );

Path Variables dialog has nothing to do with the environment variables.

Environment variables can be specified in your OS or customized in the Run configuration:

On Servlet 3.0 or newer you could just specify

<web-app ...>
    <error-page>
        <location>/general-error.html</location>
    </error-page>
</web-app>

But as you're still on Servlet 2.5, there's no other way than specifying every common HTTP error individually. You need to figure which HTTP errors the enduser could possibly face. On a barebones webapp with for example the usage of HTTP authentication, having a disabled directory listing, using custom servlets and code which can possibly throw unhandled exceptions or does not have all methods implemented, then you'd like to set it for HTTP errors 401, 403, 500 and 503 respectively.

<error-page>
    <!-- Missing login -->
    <error-code>401</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Forbidden directory listing -->
    <error-code>403</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Missing resource -->
    <error-code>404</error-code>
    <location>/Error404.html</location>
</error-page>
<error-page>
    <!-- Uncaught exception -->
    <error-code>500</error-code>
    <location>/general-error.html</location>
</error-page>
<error-page>
    <!-- Unsupported servlet method -->
    <error-code>503</error-code>
    <location>/general-error.html</location>
</error-page>

That should cover the most common ones.

Copy all order entries of home folder .iml file into your /src/main/main.iml file. This will solve the problem.

The answer to your original question

How to read a string one char at the time, and stop when you reach end of line?

is, in C++, very simply, namely: use getline. The link shows a simple example:

#include <iostream>
#include <string>
int main () {
  std::string name;
  std::cout << "Please, enter your full name: ";
  std::getline (std::cin,name);
  std::cout << "Hello, " << name << "!\n";
  return 0;
}

Do you really want to do this in C? I wouldn't! The thing is, in C, you have to allocate the memory in which to place the characters you read in? How many characters? You don't know ahead of time. If you allocate too few characters, you will have to allocate a new buffer every time to realize you reading more characters than you made room for. If you over-allocate, you are wasting space.

C is a language for low-level programming. If you are new to programming and writing simple applications for reading files line-by-line, just use C++. It does all that memory allocation for you.

Your later questions regarding "\0" and end-of-lines in general were answered by others and do apply to C as well as C++. But if you are using C, please remember that it's not just the end-of-line that matters, but memory allocation as well. And you will have to be careful not to overrun your buffer.

You can put a shadow behind the text, which can often help readability. Try experimenting with 50% translucent black shadows on your green text. Details on how to do this are over here: Android - shadow on text?

To really add a stroke around the text, you need to do something a bit more involved, like this: How do you draw text with a border on a MapView in Android?

iPhone & iPod touch:

<link rel="stylesheet" media="only screen and (max-device-width: 480px)" href="../iphone.css" type="text/css" />

iPhone 4 & iPod touch 4G:

<link rel="stylesheet" media="only screen and (-webkit-min-device-pixel-ratio: 2)" type="text/css" href="../iphone4.css" />

iPad:

<link rel="stylesheet" media="only screen and (max-device-width: 1024px)" href="../ipad.css" type="text/css" />

Use the password_verify() function

if (password_vertify($inputpassword, $row['password'])) {
  print "Logged in";
else {
    print "Password Incorrect";
}

You can iterate over "a file", which produces lines, including the trailing newline character. To make a "virtual file" out of a string, you can use StringIO:

import io  # for Py2.7 that would be import cStringIO as io

for line in io.StringIO(foo):
    print(repr(line))

Here's an example that actually filters for BIN files. Also Windows now want you to save files to user locations, not system locations, so here's an example (you can use intellisense to browse the other options):

            var saveFileDialog = new Microsoft.Win32.SaveFileDialog()
            {
                DefaultExt = "*.xml",
                Filter = "BIN Files (*.bin)|*.bin",
                InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
            };

            var result = saveFileDialog.ShowDialog();
            if (result != null && result == true)
            {
                // Save the file here
            }

Editor warning: This solution is computationally inefficient and may bring down your connection for a large table.

NB - You need to do this first on a test copy of your table!

When I did it, I found that unless I also included AND n1.id <> n2.id, it deleted every row in the table.

1. If you want to keep the row with the lowest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id > n2.id AND n1.name = n2.name
   

2. If you want to keep the row with the highest id value:

   DELETE n1 FROM names n1, names n2 WHERE n1.id < n2.id AND n1.name = n2.name
   

I used this method in MySQL 5.1

Not sure about other versions.

Update: Since people Googling for removing duplicates end up here
Although the OP's question is about DELETE, please be advised that using INSERT and DISTINCT is much faster. For a database with 8 million rows, the below query took 13 minutes, while using DELETE, it took more than 2 hours and yet didn't complete.

INSERT INTO tempTableName(cellId,attributeId,entityRowId,value)
    SELECT DISTINCT cellId,attributeId,entityRowId,value
    FROM tableName;

Even though this question already has a ton of answers I still thought I would give a shoutout to a small plugin I wrote: commentify.

Commentify uses the commentstring setting to decide how to comment out a block of code, so you don't have to keep a mapping of different comment types in your configuration, and supports both line based comments (eg, //) and block comments (eg, /* */).

It also maps the same shortcut (defaults to ctrl+c) for both commenting and uncommenting the block, so you don't have to remember two mappings or a complex set of commands.

Used below code to display custom list in AlertDialog

AlertDialog.Builder builderSingle = new AlertDialog.Builder(DialogActivity.this);
builderSingle.setIcon(R.drawable.ic_launcher);
builderSingle.setTitle("Select One Name:-");

final ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(DialogActivity.this, android.R.layout.select_dialog_singlechoice);
arrayAdapter.add("Hardik");
arrayAdapter.add("Archit");
arrayAdapter.add("Jignesh");
arrayAdapter.add("Umang");
arrayAdapter.add("Gatti");

builderSingle.setNegativeButton("cancel", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                dialog.dismiss();
            }
        });

builderSingle.setAdapter(arrayAdapter, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                String strName = arrayAdapter.getItem(which);
                AlertDialog.Builder builderInner = new AlertDialog.Builder(DialogActivity.this);
                builderInner.setMessage(strName);
                builderInner.setTitle("Your Selected Item is");
                builderInner.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog,int which) {
                                dialog.dismiss();
                            }
                        });
                builderInner.show();
            }
        });
builderSingle.show();

You can easily create a new tab; do like the following:

function newTab() {
     var form = document.createElement("form");
     form.method = "GET";
     form.action = "http://www.example.com";
     form.target = "_blank";
     document.body.appendChild(form);
     form.submit();
}

Just call moment as a function without any arguments:

moment()

For timezone information with moment, look at the moment-timezone package: http://momentjs.com/timezone/

It sounds like you want to use this web application as a remote control for your robot, and a core issue is that you won't want a page reload every time you perform an action, in which case, the last link you posted answers your problem.

I think you may be misunderstanding a few things about Flask. For one, you can't nest multiple functions in a single route. You're not making a set of functions available for a particular route, you're defining the one specific thing the server will do when that route is called.

With that in mind, you would be able to solve your problem with a page reload by changing your app.py to look more like this:

from flask import Flask, render_template, Response, request, redirect, url_for
app = Flask(__name__)

@app.route("/")
def index():
    return render_template('index.html')

@app.route("/forward/", methods=['POST'])
def move_forward():
    #Moving forward code
    forward_message = "Moving Forward..."
    return render_template('index.html', forward_message=forward_message);

Then in your html, use this:

<form action="/forward/" method="post">
    <button name="forwardBtn" type="submit">Forward</button>
</form>

...To execute your moving forward code. And include this:

{{ forward_message }} 

... where you want the moving forward message to appear on your template.

This will cause your page to reload, which is inevitable without using AJAX and Javascript.

i guess you mean System Programs and Application programs

System Programs makes the hardware run , Applications are for specific tasks

an Example for System Programs are Device Drivers

as for the Applications you can say web browsers , word porcessros etc

You can use it

$params = request()->all();

without

import Illuminate\Http\Request OR

use Illuminate\Support\Facades\Request OR other.

Probably, the easiest way to achieve this is to simply add the reference to the assembly and then (manually) patch the textual representation of the reference in the corresponding Visual Studio project file (extension .csproj) such that it becomes relative.

I've done this plenty of times in VS 2005 without any problems.

Things to be done to free port 80:

1. check if skype is running, exit from skype
2. check services.msc if web deployment agent service is running
3. check if IIS is running, stop it.

Once you start apache, you can sign into skype.

You need Pexpect to get the best of both worlds (expect and ssh wrappers).

$.ajax({
    type: 'POST',
    url: 'loginCheck',
    data: $(formLogin).serialize(),    
    success: function(result){
        console.log('my message' + result);
    }
});

In their latest release there's a directive called md-icon

<md-icon icon="img/icons/ic_refresh_24px.svg"></md-icon>

For React.js, you can do this with more readable code. Hope it helps.

handleCheckboxChange(e) {
  console.log('value of checkbox : ', e.target.checked);
}
render() {
  return <input type="checkbox" onChange={this.handleCheckboxChange.bind(this)} />
}

Give this parent DIV font-size:0. Write like this:

<div style="font-size:0">
  <div style="width:50%; display:inline-table;font-size:15px">A</div>
  <div style="width:50%; display:inline-table;font-size:15px">B</div>
</div>

I can recommend Elasticvue, which is modern, free and open source. It allows accessing your ES instance via browser add-ons quite easily (supports Firefox, Chrome, Edge). But there are also further ways.

Just make sure you set cors values in elasticsearch.yml appropiate.

Span does not have 'change' event by default. But you can add this event manually.

Listen to the change event of span.

$("#span1").on('change',function(){
     //Do calculation and change value of other span2,span3 here
     $("#span2").text('calculated value');
});

And wherever you change the text in span1. Trigger the change event manually.

$("#span1").text('test').trigger('change'); 

The best way to handle styling is by using classes with set of css properties.

example:

<Component className={this.getColor()} />

getColor() {
    let class = "badge m2";
    class += this.state.count===0 ? "warning" : danger;
    return class;
}

Rather than importing all of curses or shelling out just to get one control character, you can simply use (on Linux/macOS):

print(chr(27) + "[2J")

I've made short stupid script which extracts JPG and PNG files:

#!/usr/bin/php
<?php
 $dir="/home/user/.cache/chromium/Default/Cache/";//Chrome or chromium cache folder. 
 $ppl="/home/user/Desktop/temporary/"; // Place for extracted files 

 $list=scandir($dir);
 foreach ($list as $filename)
 {

 if (is_file($dir.$filename))
    {
        $cont=file_get_contents($dir.$filename);
        if  (strstr($cont,'JFIF'))
        {
            echo ($filename."  JPEG \n");
            $start=(strpos($cont,"JFIF",0)-6);
            $end=strpos($cont,"HTTP/1.1 200 OK",0);
            $cont=substr($cont,$start,$end-6);
            $wholename=$ppl.$filename.".jpg";
            file_put_contents($wholename,$cont);
            echo("Saving :".$wholename." \n" );


                }
        elseif  (strstr($cont,"\211PNG"))
        {
            echo ($filename."  PNG \n");
            $start=(strpos($cont,"PNG",0)-1);
            $end=strpos($cont,"HTTP/1.1 200 OK",0);
            $cont=substr($cont,$start,$end-1);
            $wholename=$ppl.$filename.".png";
            file_put_contents($wholename,$cont);
            echo("Saving :".$wholename." \n" );


                }
        else
        {
            echo ($filename."  UNKNOWN \n");
        }
    }
 }

try the toupper() function (#include <ctype.h>). it accepts characters as arguments, strings are made up of characters, so you'll have to iterate over each individual character that when put together comprise the string

The other answers are several years old (and do not work for Windows Phone 8.1) so I figured I'd drop in another option. I used this to parse an RSS response for a Windows Phone app:

XDocument xdoc = new XDocument();
xdoc = XDocument.Parse(xml_string);

Universal apps seem to work a bit differently; it doesn't have all the power of full-featured XAML. What worked for me is:

1. I created a list of the enum values as the enums (not converted to strings or to integers) and bound the ComboBox ItemsSource to that
2. Then I could bind the ComboBox ItemSelected to my public property whose type is the enum in question

Just for fun I whipped up a little templated class to help with this and published it to the MSDN Samples pages. The extra bits let me optionally override the names of the enums and to let me hide some of the enums. My code looks an awful like like Nick's (above), which I wish I had seen earlier.

An enumeration is something of an inverse-array. What I believe you want is this:

const char * Week[] = { "", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };  // The blank string at the beginning is so that Sunday is 1 instead of 0.
cout << "Today is " << Week[2] << ", enjoy!";  // Or whatever you'de like to do with it.

What about Transactions? They have the ROLLBACK-Feature.

@see https://dev.mysql.com/doc/refman/5.0/en/commit.html

For example:

START TRANSACTION;
SELECT * FROM nicetable WHERE somthing=1;
UPDATE nicetable SET nicefield='VALUE' WHERE somthing=1;
SELECT * FROM nicetable WHERE somthing=1; #check

COMMIT;
# or if you want to reset changes 
ROLLBACK;

SELECT * FROM nicetable WHERE somthing=1; #should be the old value

Answer on question from @rickozoe below:

In general these lines will not be executed as once. In PHP f.e. you would write something like that (perhaps a little bit cleaner, but wanted to answer quick ;-) ):

$MysqlConnection->query('START TRANSACTION;');
$erg = $MysqlConnection->query('UPDATE MyGuests SET lastname='Doe' WHERE id=2;');
if($erg)
    $MysqlConnection->query('COMMIT;');
else
    $MysqlConnection->query('ROLLBACK;');

Another way would be to use MySQL Variables (see https://dev.mysql.com/doc/refman/5.7/en/user-variables.html and https://stackoverflow.com/a/18499823/1416909 ):

# do some stuff that should be conditionally rollbacked later on

SET @v1 := UPDATE MyGuests SET lastname='Doe' WHERE id=2;
IF(v1 < 1) THEN
    ROLLBACK;
ELSE
    COMMIT;
END IF;

But I would suggest to use the language wrappers available in your favorite programming language.

I know this thread is years ago and issue was fixed too. But I hope this would helps someone else in future since I've encountered some similar issues while I tried to install Oracle WebLogic 12c and Oracle OFR in which its installer is in .jar format. For mine case, it was either didn't wrap the JDK directory in quotes or simply typo.

Run Command Prompt as administrator and execute the command in this format. Double check the sentence if there is typo.

"C:\Program Files\Java\jdk1.xxxxx\bin\java" -jar C:\Users\xxx\Downloads\xxx.jar

If it shows something like JRE 1.xxx is not a valid JDK Java Home, make sure the System variables for JAVA_HOME in Environment Variables is pointing to the correct JDK directory. JDK 1.8 or above is recommended (2018).

A useful thread here, you may refer it: Why its showing your JDK c:program files\java\jre7 is not a valid JDK while instaling weblogic server?

I've just managed to setup new TabLayout, so here are the quick steps to do this (????)?*:???

1. Add dependencies inside your build.gradle file:

   dependencies {
       compile 'com.android.support:design:23.1.1'
   }
   

2. Add TabLayout inside your layout

   <?xml version="1.0" encoding="utf-8"?>
   <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
         android:layout_width="match_parent"
         android:layout_height="match_parent"
         android:orientation="vertical">
   
       <android.support.v7.widget.Toolbar
           android:id="@+id/toolbar"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:background="?attr/colorPrimary"/>
   
       <android.support.design.widget.TabLayout
           android:id="@+id/tab_layout"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"/>
   
       <android.support.v4.view.ViewPager
           android:id="@+id/pager"
           android:layout_width="match_parent"
           android:layout_height="match_parent"/>
   
   </LinearLayout>
   

3. Setup your Activity like this:

   import android.os.Bundle;
   import android.support.design.widget.TabLayout;
   import android.support.v4.app.Fragment;
   import android.support.v4.app.FragmentManager;
   import android.support.v4.app.FragmentPagerAdapter;
   import android.support.v4.view.ViewPager;
   import android.support.v7.app.AppCompatActivity;
   import android.support.v7.widget.Toolbar;
   
   public class TabLayoutActivity extends AppCompatActivity {
   
       @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_pull_to_refresh);
   
           Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
           TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
           ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
   
           if (toolbar != null) {
               setSupportActionBar(toolbar);
           }
   
           viewPager.setAdapter(new SectionPagerAdapter(getSupportFragmentManager()));
           tabLayout.setupWithViewPager(viewPager);
       }
   
       public class SectionPagerAdapter extends FragmentPagerAdapter {
   
           public SectionPagerAdapter(FragmentManager fm) {
               super(fm);
           }
   
           @Override
           public Fragment getItem(int position) {
               switch (position) {
                   case 0:
                       return new FirstTabFragment();
                   case 1:
                   default:
                       return new SecondTabFragment();
               }
           }
   
           @Override
           public int getCount() {
               return 2;
           }
   
           @Override
           public CharSequence getPageTitle(int position) {
               switch (position) {
                   case 0:
                       return "First Tab";
                   case 1:
                   default:
                       return "Second Tab";
               }
           }
       }
   
   }
   

You override __hash__ if you want special hash-semantics, and __cmp__ or __eq__ in order to make your class usable as a key. Objects who compare equal need to have the same hash value.

Python expects __hash__ to return an integer, returning Banana() is not recommended :)

User defined classes have __hash__ by default that calls id(self), as you noted.

There is some extra tips from the documentation.:

Classes which inherit a __hash__() method from a parent class but change the meaning of __cmp__() or __eq__() such that the hash value returned is no longer appropriate (e.g. by switching to a value-based concept of equality instead of the default identity based equality) can explicitly flag themselves as being unhashable by setting __hash__ = None in the class definition. Doing so means that not only will instances of the class raise an appropriate TypeError when a program attempts to retrieve their hash value, but they will also be correctly identified as unhashable when checking isinstance(obj, collections.Hashable) (unlike classes which define their own __hash__() to explicitly raise TypeError).

If you are simply looking to make the input relative to the screen width, an easy way would be to use Dimensions:

// De structure Dimensions from React
var React = require('react-native');
var {
  ...
  Dimensions
} = React; 

// Store width in variable
var width = Dimensions.get('window').width; 

// Use width variable in style declaration
<TextInput style={{ width: width * .8 }} />

I've set up a working project here. Code is also below.

https://rnplay.org/apps/rqQPCQ

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TextInput,
  Dimensions
} = React;

var width = Dimensions.get('window').width;

var SampleApp = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <Text style={{fontSize:22}}>Percentage Width In React Native</Text>
        <View style={{marginTop:100, flexDirection: 'row',justifyContent: 'center'}}>
            <TextInput style={{backgroundColor: '#dddddd', height: 60, width: width*.8 }} />
          </View>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop:100
  },

});

AppRegistry.registerComponent('SampleApp', () => SampleApp);

Use a HashSet<T>. For example:

var items = "A B A D A C".Split(' ');
var unique_items = new HashSet<string>(items);
foreach (string s in unique_items)
    Console.WriteLine(s);

prints

A
B
D
C

Another way is to select a column with the columns array:

In [5]: df = pd.DataFrame([[1,2], [3,4]], columns=['a', 'b'])

In [6]: df
Out[6]: 
   a  b
0  1  2
1  3  4

In [7]: df[df.columns[0]]
Out[7]: 
0    1
1    3
Name: a, dtype: int64

To insert/append to a dictionary

{"0": {"travelkey":"value", "travelkey2":"value"},"1":{"travelkey":"value","travelkey2":"value"}} 

travel_dict={} #initialize dicitionary 
travel_key=0 #initialize counter

if travel_key not in travel_dict: #for avoiding keyerror 0
    travel_dict[travel_key] = {}
travel_temp={val['key']:'no flexible'}  
travel_dict[travel_key].update(travel_temp) # Updates if val['key'] exists, else adds val['key']
travel_key=travel_key+1

The ruby version 1.8.7 seems to be your system ruby.

Normally you can choose the ruby version you'd like, if you are using rvm with following. Simple change into your directory in a new terminal and type in:

rvm use 2.0.0

You can find more details about rvm here: http://rvm.io Open the website and scroll down, you will see a few helpful links. "Setting up default rubies" for example could help you.

Update: To set the ruby as default:

rvm use 2.0.0 --default

It'll be because response[0] itself is undefined.

@alvas has a good answer. But again it depends on the nature of the task, for example in your application you want to consider all conjunction e.g. and, or, but, if, while and all determiner e.g. the, a, some, most, every, no as stop words considering all others parts of speech as legitimate, then you might want to look into this solution which use Part-of-Speech Tagset to discard words, Check table 5.1:

import nltk

STOP_TYPES = ['DET', 'CNJ']

text = "some data here "
tokens = nltk.pos_tag(nltk.word_tokenize(text))
good_words = [w for w, wtype in tokens if wtype not in STOP_TYPES]

}

Your sum

v1 + (incident edges) + v2 + (incident edges) + .... + vn + (incident edges)

can be rewritten as

(v1 + v2 + ... + vn) + [(incident_edges v1) + (incident_edges v2) + ... + (incident_edges vn)]

and the first group is O(N) while the other is O(E).

I imagine everyone knows what cors is and what it is for. In a simple way and for example if you use nodejs and express for the management, enable it is like this

Dependency:

https://www.npmjs.com/package/cors

app.use (
   cors ({
     origin: "*",
    ... more
   })
);

And for the problem of browser requests locally, it is only to install this extension of google chrome.

Name: Allow CORS: Access-Control-Allow-Origin

https://chrome.google.com/webstore/detail/allow-cors-access-control/lhobafahddgcelffkeicbaginigeejlf?hl=es

This allows you to enable and disable cros in local, and problem solved.

for (Int32 i = 1; i < dt_pattern.Rows.Count - 1; i++){ double yATmax = ToDouble(dt_pattern.Rows[i]["Ampl"].ToString()) + AT; }

if you want to get around the + 1 issue

Do the following:

Dim dataTable1 As New DataTable
                dataTable1.Columns.Add("FECHA")
                dataTable1.Columns.Add("TT")
                dataTable1.Columns.Add("DESCRIPCION")
                dataTable1.Columns.Add("No. DOC")
                dataTable1.Columns.Add("DEBE")
                dataTable1.Columns.Add("HABER")
                dataTable1.Columns.Add("SALDO")

For Each line As String In System.IO.File.ReadAllLines(objetos.url)
                    dataTable1.Rows.Add(line.Split(","))
                Next

Note: This answer shows how to achieve this using only the datetime and calendar standard library (stdlib) modules - which is what was explicitly asked for. The accepted answer shows how to better achieve this with one of the many dedicated non-stdlib libraries. If you can use non-stdlib libraries, by all means do so for these kinds of date/time manipulations!

How about this?

def add_one_month(orig_date):
    # advance year and month by one month
    new_year = orig_date.year
    new_month = orig_date.month + 1
    # note: in datetime.date, months go from 1 to 12
    if new_month > 12:
        new_year += 1
        new_month -= 12

    new_day = orig_date.day
    # while day is out of range for month, reduce by one
    while True:
        try:
            new_date = datetime.date(new_year, new_month, new_day)
        except ValueError as e:
            new_day -= 1
        else:
            break

    return new_date

EDIT:

Improved version which:

1. keeps the time information if given a datetime.datetime object
2. doesn't use try/catch, instead using calendar.monthrange from the calendar module in the stdlib:

import datetime
import calendar

def add_one_month(orig_date):
    # advance year and month by one month
    new_year = orig_date.year
    new_month = orig_date.month + 1
    # note: in datetime.date, months go from 1 to 12
    if new_month > 12:
        new_year += 1
        new_month -= 12

    last_day_of_month = calendar.monthrange(new_year, new_month)[1]
    new_day = min(orig_date.day, last_day_of_month)

    return orig_date.replace(year=new_year, month=new_month, day=new_day)
