In VB.NET, you need to use the GetType method to retrieve the type of an instance of an object, and the GetType() operator to retrieve the type of another known type.

Once you have the two types, you can simply compare them using the Is operator.

So your code should actually be written like this:

Sub FillCategories(ByVal Obj As Object)
    Dim cmd As New SqlCommand("sp_Resources_Categories", Conn)
    cmd.CommandType = CommandType.StoredProcedure
    Obj.DataSource = cmd.ExecuteReader
    If Obj.GetType() Is GetType(System.Web.UI.WebControls.DropDownList) Then

    End If
    Obj.DataBind()
End Sub

You can also use the TypeOf operator instead of the GetType method. Note that this tests if your object is compatible with the given type, not that it is the same type. That would look like this:

If TypeOf Obj Is System.Web.UI.WebControls.DropDownList Then

End If

Totally trivial, irrelevant nitpick: Traditionally, the names of parameters are camelCased (which means they always start with a lower-case letter) when writing .NET code (either VB.NET or C#). This makes them easy to distinguish at a glance from classes, types, methods, etc.

It is called the ternary operator. It is shorthand for an if-else block. See here for an example http://www.php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary

Within a constructor, you can use the this keyword to invoke another constructor in the same class. Doing so is called an explicit constructor invocation.

Here's another Rectangle class, with a different implementation from the one in the Objects section.

public class Rectangle {
    private int x, y;
    private int width, height;

    public Rectangle() {
        this(1, 1);
    }
    public Rectangle(int width, int height) {
        this( 0,0,width, height);
    }
    public Rectangle(int x, int y, int width, int height) {
        this.x = x;
        this.y = y;
        this.width = width;
        this.height = height;
    }

}

This class contains a set of constructors. Each constructor initializes some or all of the rectangle's member variables.

If you are using the boost libraries, you can use boost::bind to access the second value of the pair as follows:

#include <string>
#include <map>
#include <vector>
#include <algorithm>
#include <boost/bind.hpp>

int main()
{
   typedef std::map<std::string, int> MapT;
   typedef std::vector<int> VecT;
   MapT map;
   VecT vec;

   map["one"] = 1;
   map["two"] = 2;
   map["three"] = 3;
   map["four"] = 4;
   map["five"] = 5;

   std::transform( map.begin(), map.end(),
                   std::back_inserter(vec),
                   boost::bind(&MapT::value_type::second,_1) );
}

This solution is based on a post from Michael Goldshteyn on the boost mailing list.

What Thomas has written is correct, in addition to that, if you want to initialize multiple schemas you can use the following. Note there is a \\; separating the two create statements.

    EmbeddedDatabase db = new EmbeddedDatabaseBuilder()
                    .setType(EmbeddedDatabaseType.H2)
                    .setName("testDb;DB_CLOSE_ON_EXIT=FALSE;MODE=Oracle;INIT=create " +
                            "schema if not exists " +
                            "schema_a\\;create schema if not exists schema_b;" +
                            "DB_CLOSE_DELAY=-1;")
                    .addScript("sql/provPlan/createTable.sql")
                    .addScript("sql/provPlan/insertData.sql")
                    .addScript("sql/provPlan/insertSpecRel.sql")
                    .build();

A pipe takes in data as input and transforms it to a desired output. Add this pipe file:orderby.ts inside your /app folder .

orderby.ts

//The pipe class implements the PipeTransform interface's transform method that accepts an input value and an optional array of parameters and returns the transformed value.

import { Pipe,PipeTransform } from "angular2/core";

//We tell Angular that this is a pipe by applying the @Pipe decorator which we import from the core Angular library.

@Pipe({

  //The @Pipe decorator takes an object with a name property whose value is the pipe name that we'll use within a template expression. It must be a valid JavaScript identifier. Our pipe's name is orderby.

  name: "orderby"
})

export class OrderByPipe implements PipeTransform {
  transform(array:Array<any>, args?) {

    // Check if array exists, in this case array contains articles and args is an array that has 1 element : !id

    if(array) {

      // get the first element

      let orderByValue = args[0]
      let byVal = 1

      // check if exclamation point 

      if(orderByValue.charAt(0) == "!") {

        // reverse the array

        byVal = -1
        orderByValue = orderByValue.substring(1)
      }
      console.log("byVal",byVal);
      console.log("orderByValue",orderByValue);

      array.sort((a: any, b: any) => {
        if(a[orderByValue] < b[orderByValue]) {
          return -1*byVal;
        } else if (a[orderByValue] > b[orderByValue]) {
          return 1*byVal;
        } else {
          return 0;
        }
      });
      return array;
    }
    //
  }
}

In your component file (app.component.ts) import the pipe that you just added using: import {OrderByPipe} from './orderby';

Then, add *ngFor="#article of articles | orderby:'id'" inside your template if you want to sort your articles by id in ascending order or orderby:'!id'" in descending order.

We add parameters to a pipe by following the pipe name with a colon ( : ) and then the parameter value

We must list our pipe in the pipes array of the @Component decorator. pipes: [ OrderByPipe ] .

app.component.ts

import {Component, OnInit} from 'angular2/core';
import {OrderByPipe} from './orderby';

@Component({
    selector: 'my-app',
    template: `
      <h2>orderby-pipe by N2B</h2>
      <p *ngFor="#article of articles | orderby:'id'">
        Article title : {{article.title}}
      </p>
    `,
    pipes: [ OrderByPipe ]

})
export class AppComponent{
    articles:Array<any>
    ngOnInit(){
        this.articles = [
        {
            id: 1,
            title: "title1"
        },{
            id: 2,
            title: "title2",
        }]  
    }

}

 def getNthBusinessDay(startDate, businessDaysInBetween):
    currentDate = startDate
    daysToAdd = businessDaysInBetween
    while daysToAdd > 0:
        currentDate += relativedelta(days=1)
        day = currentDate.weekday()

you can just use JSON.stringify to test your Object, like this:

var test = {}_x000D_
if(JSON.stringify(test)[0] === '{') {_x000D_
  console.log('this is a Object')_x000D_
}

$last = array_slice($array, -1, 1, true);

See http://php.net/array_slice for details on what the arguments mean.

P.S. Unlike the other answers, this one actually does what you want. :-)

With bootstrap 3 the best way to go about achieving what you want is ...with offsetting columns. Please see these examples for more detail:
http://getbootstrap.com/css/#grid-offsetting

In short, and without seeing your divs here's an example what might help, without using any custom classes. Just note how the "col-6" is used and how half of that is 3 ...so the "offset-3" is used. Splitting equally will allow the centered spacing you're going for:

<div class="container">
<div class="col-sm-6 col-sm-offset-3">
your centered, floating column
</div></div>

WiFi can be enabled by altering the settings.db like so:

adb shell
sqlite3 /data/data/com.android.providers.settings/databases/settings.db
update secure set value=1 where name='wifi_on';

You may need to reboot after altering this to get it to actually turn WiFi on.

This solution comes from a blog post that remarks it works for Android 4.0. I don't know if the earlier versions are the same.

It was changed between 3.1 and 3.2:

This is a terse description of the new features added to bash-3.2 since the release of bash-3.1.

Quoting the string argument to the [[ command's =~ operator now forces string matching, as with the other pattern-matching operators.

So use it without the quotes thus:

i="test"
if [[ $i =~ 200[78] ]] ; then
    echo "OK"
else
    echo "not OK"
fi

You just need to add a jquery selector after the url.

See: http://api.jquery.com/load/

Example straight from the API:

$('#result').load('ajax/test.html #container');

So what that does is it loads the #container element from the specified url.

When you have a conflict during rebase you have three options:

• You can run git rebase --abort to completely undo the rebase. Git will return you to your branch's state as it was before git rebase was called.

• You can run git rebase --skip to completely skip the commit. That means that none of the changes introduced by the problematic commit will be included. It is very rare that you would choose this option.

• You can fix the conflict as iltempo said. When you're finished, you'll need to call git rebase --continue. My mergetool is kdiff3 but there are many more which you can use to solve conflicts. You only need to set your merge tool in git's settings so it can be invoked when you call git mergetool https://git-scm.com/docs/git-mergetool

If none of the above works for you, then go for a walk and try again :)

Okay. I don't know how but this worked.

First I cleaned the project and then, running the project made everything go alright.

Inshort, First Clean and then Run.

Edit First Clean and then Make Project also works.

you could use something like:

[^0-9]+([0-9]+)[^0-9]+([0-9]+).+

Then get the first and second capture groups.

I got same problem and I solved it using these steps.

1)Remove your .gradle file.(uuslly it in C:\Users{your_PC_name}

2)then go to the environment variable and add these to the system variable(as a new variable)

Variable name : _JAVA_OPTIONS

Variable value: -Xmx524m

3)go to your project folder and run these command

ionic cordova platform add android

4)Above command create platform folder in your project path

5)then run this command

ionic cordova build android

TLDR Summary

In modern MongoDB releases you can brute force this with $slice just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push to an array.

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$project": {
        "books": { "$slice": [ "$books", 2 ] },
        "count": 1
    }}
])

MongoDB 3.6 Preview

Still not resolving SERVER-9377, but in this release $lookup allows a new "non-correlated" option which takes an "pipeline" expression as an argument instead of the "localFields" and "foreignFields" options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit in order to return the "top-n" results.

db.books.aggregate([
  { "$group": {
    "_id": "$addr",
    "count": { "$sum": 1 }
  }},
  { "$sort": { "count": -1 } },
  { "$limit": 2 },
  { "$lookup": {
    "from": "books",
    "let": {
      "addr": "$_id"
    },
    "pipeline": [
      { "$match": { 
        "$expr": { "$eq": [ "$addr", "$$addr"] }
      }},
      { "$group": {
        "_id": "$book",
        "count": { "$sum": 1 }
      }},
      { "$sort": { "count": -1  } },
      { "$limit": 2 }
    ],
    "as": "books"
  }}
])

The other addition here is of course the ability to interpolate the variable through $expr using $match to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit each result separately.

This would be the next best option to running parallel queries, and actually would be better if the $match were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push" as the referenced issue asks, it actually delivers something that should work better.

Original Content

You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 }
])

Now that will give you a result like this:

{
    "result" : [
            {
                    "_id" : "address1",
                    "books" : [
                            {
                                    "book" : "book4",
                                    "count" : 1
                            },
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 3
                            }
                    ],
                    "count" : 5
            },
            {
                    "_id" : "address2",
                    "books" : [
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 2
                            }
                    ],
                    "count" : 3
            }
    ],
    "ok" : 1
}

So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.

This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$unwind": "$books" },
    { "$sort": { "count": 1, "books.count": -1 } },
    { "$group": {
        "_id": "$_id",
        "books": { "$push": "$books" },
        "count": { "$first": "$count" }
    }},
    { "$project": {
        "_id": {
            "_id": "$_id",
            "books": "$books",
            "count": "$count"
        },
        "newBooks": "$books"
    }},
    { "$unwind": "$newBooks" },
    { "$group": {
      "_id": "$_id",
      "num1": { "$first": "$newBooks" }
    }},
    { "$project": {
        "_id": "$_id",
        "newBooks": "$_id.books",
        "num1": 1
    }},
    { "$unwind": "$newBooks" },
    { "$project": {
        "_id": "$_id",
        "num1": 1,
        "newBooks": 1,
        "seen": { "$eq": [
            "$num1",
            "$newBooks"
        ]}
    }},
    { "$match": { "seen": false } },
    { "$group":{
        "_id": "$_id._id",
        "num1": { "$first": "$num1" },
        "num2": { "$first": "$newBooks" },
        "count": { "$first": "$_id.count" }
    }},
    { "$project": {
        "num1": 1,
        "num2": 1,
        "count": 1,
        "type": { "$cond": [ 1, [true,false],0 ] }
    }},
    { "$unwind": "$type" },
    { "$project": {
        "books": { "$cond": [
            "$type",
            "$num1",
            "$num2"
        ]},
        "count": 1
    }},
    { "$group": {
        "_id": "$_id",
        "count": { "$first": "$count" },
        "books": { "$push": "$books" }
    }},
    { "$sort": { "count": -1 } }
])

So that will actually give you the top 2 "books" from the top two "address" entries.

But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.

Demonstration Code

The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

index.js

const { MongoClient } = require('mongodb');
const fs = require('mz/fs');

const uri = 'mongodb://localhost:27017';

const log = data => console.log(JSON.stringify(data, undefined, 2));

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

Here is my one liner. Here 'c' is the name of the column

df.select('c').withColumn('isNull_c',F.col('c').isNull()).where('isNull_c = True').count()

Now there is a Native support in SQL Server (CTP3) for import, export, query and validate JSON inside T-SQL Refer to https://msdn.microsoft.com/en-us/library/dn921897.aspx

In Python string literals, backslash is an escape character. This is also true when the interactive prompt shows you the value of a string. It will give you the literal code representation of the string. Use the print statement to see what the string actually looks like.

This example shows the difference:

>>> '\\'
'\\'
>>> print '\\'
\

You can't do replacing, you have to replace SOMETHING with SOMETHING, and you neither have both.

You can use MD5() in mysql or md5() in php. To use salt add it to password before running md5, f.e.:

$salt ='my_string';
$hash = md5($salt . $password);

It's better to use different salt for every password. For this you have to save your salt in db (and also hash). While authentication user will send his login and pass. You will find his hash and salt in db and find out:

if ($hash == md5($salt . $_POST['password'])) {}

From MSDN, Math.Round(double a) returns:

The integer nearest a. If the fractional component of a is halfway between two integers, one of which is even and the other odd, then the even number is returned.

... and so 2.5, being halfway between 2 and 3, is rounded down to the even number (2). this is called Banker's Rounding (or round-to-even), and is a commonly-used rounding standard.

Same MSDN article:

The behavior of this method follows IEEE Standard 754, section 4. This kind of rounding is sometimes called rounding to nearest, or banker's rounding. It minimizes rounding errors that result from consistently rounding a midpoint value in a single direction.

You can specify a different rounding behavior by calling the overloads of Math.Round that take a MidpointRounding mode.

The script containing variables can be executed imported using bash. Consider the script-variable.sh

#!/bin/sh
scr-var=value

Consider the actual script where the variable will be used :

 #!/bin/sh
 bash path/to/script-variable.sh
 echo "$scr-var"

Try these ...

Option1

window.location=document.referrer;

Option2

window.location.reload(history.back());

Android no longer downloading the libraries from the SDK manager, it has to be accessed through Google's Maven repository.

You will have to do something similar to this in your build.gradle file:

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}



dependencies {
    ...
    compile "com.android.support:support-core-utils:27.0.2"
}

Find more details about the setting up process here and about the different support library revisions here.

You can simply use the toCharArray() to convert a string to char array:

    Scanner s=new Scanner(System.in);
    System.out.print("Enter some String:");
    String str=s.nextLine();
    char a[]=str.toCharArray();

The setInterval function returns an integer value, which is the id of the "timer instance" that you've created.

It is this integer value that you need to pass to clearInterval

e.g:

var timerID = setInterval(fontChange,500);

and later

clearInterval(timerID);

You are asking for the condition where all the conditions are true, so len of the frame is the answer, unless I misunderstand what you are asking

In [17]: df = DataFrame(randn(20,4),columns=list('ABCD'))

In [18]: df[(df['A']>0) & (df['B']>0) & (df['C']>0)]
Out[18]:

I have figured out how this is done for Sony devices.

I've blogged about it here. I've also posted a seperate SO question about this here.

Sony devices use a class named BadgeReciever.

1. Declare the com.sonyericsson.home.permission.BROADCAST_BADGE permission in your manifest file:

2. Broadcast an Intent to the BadgeReceiver:

   Intent intent = new Intent();
   
   intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
   intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
   
   sendBroadcast(intent);
   

3. Done. Once this Intent is broadcast the launcher should show a badge on your application icon.

4. To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE set to false:

   intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
   

I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.

Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.

e.g. if you do this:

SELECT 1 / 2

you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.

e.g.

SELECT CAST(1 AS DECIMAL) / 2

gives 0.500000

3 draggable buttons in a div, dragging constrained by div.

<div id="parent" class="parent">
    <button id="button1" class="button">Drag me</button>
    <button id="button2" class="button">Drag me</button>
    <button id="button3" class="button">Drag me</button>
</div>
<div id="log1"></div>
<div id="log2"></div>

Requires JQuery (only):

$(function() {
    $('.button').mousedown(function(e) {
        if(e.which===1) {
            var button = $(this);
            var parent_height = button.parent().innerHeight();
            var top = parseInt(button.css('top')); //current top position
            var original_ypos = button.css('top','').position().top; //original ypos (without top)
            button.css({top:top+'px'}); //restore top pos
            var drag_min_ypos = 0-original_ypos;
            var drag_max_ypos = parent_height-original_ypos-button.outerHeight();
            var drag_start_ypos = e.clientY;
            $('#log1').text('mousedown top: '+top+', original_ypos: '+original_ypos);
            $(window).on('mousemove',function(e) {
                //Drag started
                button.addClass('drag');
                var new_top = top+(e.clientY-drag_start_ypos);
                button.css({top:new_top+'px'});
                if(new_top<drag_min_ypos) { button.css({top:drag_min_ypos+'px'}); }
                if(new_top>drag_max_ypos) { button.css({top:drag_max_ypos+'px'}); }
                $('#log2').text('mousemove min: '+drag_min_ypos+', max: '+drag_max_ypos+', new_top: '+new_top);
                //Outdated code below (reason: drag contrained too early)
                /*if(new_top>=drag_min_ypos&&new_top<=drag_max_ypos) {
                    button.css({top:new_top+'px'});
                }*/
            });
            $(window).on('mouseup',function(e) {
                 if(e.which===1) {
                    //Drag finished
                    $('.button').removeClass('drag');
                    $(window).off('mouseup mousemove');
                    $('#log1').text('mouseup');
                    $('#log2').text('');
                 }
            });
        }
    });
});

this is how i did it:

String[] listAges = getResources().getStringArray(R.array.ages);

        // Creating adapter for spinner
        ArrayAdapter<String> dataAdapter =
                new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, listAges);

        // Drop down layout style - list view with radio button
        dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        // attaching data adapter to spinner
        spinner_age.getBackground().setColorFilter(ContextCompat.getColor(this, R.color.spinner_icon), PorterDuff.Mode.SRC_ATOP);
        spinner_age.setAdapter(dataAdapter);
        spinner_age.setSelection(0);
        spinner_age.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                String item = parent.getItemAtPosition(position).toString();

                if(position > 0){
                    // get spinner value
                    Toast.makeText(parent.getContext(), "Age..." + item, Toast.LENGTH_SHORT).show();
                }else{
                    // show toast select gender
                    Toast.makeText(parent.getContext(), "none" + item, Toast.LENGTH_SHORT).show();
                }
            }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        });

git describe is a porcelain command, which you should avoid:

Instead, I used:

git name-rev --tags --name-only $(git rev-parse HEAD)

Remember that your img is not really a DOM element but a javascript expression.

1. This is a JSX attribute expression. Put curly braces around the src string expression and it will work. See http://facebook.github.io/react/docs/jsx-in-depth.html#attribute-expressions

2. In javascript, the class attribute is reference using className. See the note in this section: http://facebook.github.io/react/docs/jsx-in-depth.html#react-composite-components

   /** @jsx React.DOM */
   
   var Hello = React.createClass({
       render: function() {
           return <div><img src={'http://placehold.it/400x20&text=slide1'} alt="boohoo" className="img-responsive"/><span>Hello {this.props.name}</span></div>;
       }
   });
   
   React.renderComponent(<Hello name="World" />, document.body);
   

Personally, I just use JSON to convert things to strings and back. Strings I understand.

import json
s = [('yellow', 1), ('blue', 2), ('yellow', 3), ('blue', 4), ('red', 1)]
mydict = {}
hash = json.dumps(s)
mydict[hash] = "whatever"
print mydict
#{'[["yellow", 1], ["blue", 2], ["yellow", 3], ["blue", 4], ["red", 1]]': 'whatever'}

Make sure Anonymous access is enabled on IIS -> Authentication.

But also right click on it, then click on Edit, and choose a domain\username and password. (With access to the physical folder of the application).

For me, I have to Revoke USB debugging authorizations in Developer Options. Here is the steps:

1. Turn off USB Debugging,
2. Revoke USB debugging authorizations,
3. Plug the cable back in,
4. Turn on USB Debugging

for(begin; begin<end; begin)
    Console.WriteLine(System.Guid.NewGuid().ToString());

You aren't incrementing begin so the condition begin < end is always true.

Add a jQuery function,

(function($){
    $.fn.regex = function(pattern, fn, fn_a){
        var fn = fn || $.fn.text;
        return this.filter(function() {
            return pattern.test(fn.apply($(this), fn_a));
        });
    };
})(jQuery);

Then,

$('span').regex(/Sent/)

will select all span elements with text matches /Sent/.

$('span').regex(/tooltip.year/, $.fn.attr, ['class'])

will select all span elements with their classes match /tooltip.year/.

The current answers are fine and should work ok, but what's wrong with the more simple, more obvious, and more maintainable:

IF @flag = 1
    UPDATE table_name SET column_A = column_A + @new_value WHERE ID = @ID;
ELSE
    UPDATE table_name SET column_B = column_B + @new_value WHERE ID = @ID;

This is much easier to read albeit this is a very simple query.

Here's a working example courtesy of @snyder: SqlFiddle.

(Tested for pandas 1.0.5)
Based on @athlonshi answer (it had ValueError: could not convert string to float: 'big', on C column), full working example without warning:

import pandas as pd
from sklearn.preprocessing import MinMaxScaler
scale = preprocessing.MinMaxScaler()

df = pd.DataFrame({
           'A':[14.00,90.20,90.95,96.27,91.21],
           'B':[103.02,107.26,110.35,114.23,114.68], 
           'C':['big','small','big','small','small']
         })
print(df)
df[["A","B"]] = pd.DataFrame(scale.fit_transform(df[["A","B"]].values), columns=["A","B"], index=df.index)
print(df)

       A       B      C
0  14.00  103.02    big
1  90.20  107.26  small
2  90.95  110.35    big
3  96.27  114.23  small
4  91.21  114.68  small
          A         B      C
0  0.000000  0.000000    big
1  0.926219  0.363636  small
2  0.935335  0.628645    big
3  1.000000  0.961407  small
4  0.938495  1.000000  small

One other thing to look at that solved it for me :

In an Eclipse / Maven project, I had Java classes in src/test/java in which I was using the this.getClass().getResource("someFile.ext"); pattern to look for resources in src/test/resources where the resource file was in the same package location in the resources source folder as the test class was in the the test source folder. It still failed to locate them.

Right click on the src/test/resources source folder, Build Path, then "configure inclusion / exclusion filters"; I added a new inclusion filter of **/*.ext to make sure my files weren't getting scrubbed; my tests now can find their resource files.

I recently ran into an issue with IEnumerable v. IQueryable. The algorithm being used first performed an IQueryable query to obtain a set of results. These were then passed to a foreach loop, with the items instantiated as an Entity Framework (EF) class. This EF class was then used in the from clause of a Linq to Entity query, causing the result to be IEnumerable.

I'm fairly new to EF and Linq for Entities, so it took a while to figure out what the bottleneck was. Using MiniProfiling, I found the query and then converted all of the individual operations to a single IQueryable Linq for Entities query. The IEnumerable took 15 seconds and the IQueryable took 0.5 seconds to execute. There were three tables involved and, after reading this, I believe that the IEnumerable query was actually forming a three table cross-product and filtering the results.

Try to use IQueryables as a rule-of-thumb and profile your work to make your changes measurable.

You can use a BehaviorSubject for communicating between different components throughout the app. You can define a data sharing service containing the BehaviorSubject to which you can subscribe and emit changes.

Define a data sharing service

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable()
export class DataSharingService {
    public isUserLoggedIn: BehaviorSubject<boolean> = new BehaviorSubject<boolean>(false);
}

Add the DataSharingService in your AppModule providers entry.

Next, import the DataSharingService in your <app-header> and in the component where you perform the sign-in operation. In <app-header> subscribe to the changes to isUserLoggedIn subject:

import { DataSharingService } from './data-sharing.service';

export class AppHeaderComponent { 
    // Define a variable to use for showing/hiding the Login button
    isUserLoggedIn: boolean;

    constructor(private dataSharingService: DataSharingService) {

        // Subscribe here, this will automatically update 
        // "isUserLoggedIn" whenever a change to the subject is made.
        this.dataSharingService.isUserLoggedIn.subscribe( value => {
            this.isUserLoggedIn = value;
        });
    }
}

In your <app-header> html template, you need to add the *ngIf condition e.g.:

<button *ngIf="!isUserLoggedIn">Login</button> 
<button *ngIf="isUserLoggedIn">Sign Out</button>

Finally, you just need to emit the event once the user has logged in e.g:

someMethodThatPerformsUserLogin() {
    // Some code 
    // .....
    // After the user has logged in, emit the behavior subject changes.
    this.dataSharingService.isUserLoggedIn.next(true);
}

OK turns out what you really want is this: http://inputsimulator.codeplex.com/

Which has done all the hard work of exposing the Win32 SendInput methods to C#. This allows you to directly send the windows key. This is tested and works:

InputSimulator.SimulateModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.VK_E);

Note however that in some cases you want to specifically send the key to the application (such as ALT+F4), in which case use the Form library method. In others, you want to send it to the OS in general, use the above.

Old

Keeping this here for reference, it will not work in all operating systems, and will not always behave how you want. Note that you're trying to send these key strokes to the app, and the OS usually intercepts them early. In the case of Windows 7 and Vista, too early (before the E is sent).

SendWait("^({ESC}E)") or Send("^({ESC}E)")

Note from here: http://msdn.microsoft.com/en-us/library/system.windows.forms.sendkeys.aspx

To specify that any combination of SHIFT, CTRL, and ALT should be held down while several other keys are pressed, enclose the code for those keys in parentheses. For example, to specify to hold down SHIFT while E and C are pressed, use "+(EC)". To specify to hold down SHIFT while E is pressed, followed by C without SHIFT, use "+EC".

Note that since you want ESC and (say) E pressed at the same time, you need to enclose them in brackets.

Probably "new f-strings in Python 3.6" is the most efficient way of concatenating strings.

Using %s

>>> timeit.timeit("""name = "Some"
... age = 100
... '%s is %s.' % (name, age)""", number = 10000)
0.0029734770068898797

Using .format

>>> timeit.timeit("""name = "Some"
... age = 100
... '{} is {}.'.format(name, age)""", number = 10000)
0.004015227983472869

Using f

>>> timeit.timeit("""name = "Some"
... age = 100
... f'{name} is {age}.'""", number = 10000)

you have to call a function before it can return anything.

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction();
}

var test = mainFunction();
alert(test);

Or:

function mainFunction() {
      function subFunction() {
            var str = "foo";
            return str;
      }
      return subFunction;
}

var test = mainFunction();
alert( test() );

for your actual code. The return should be outside, in the main function. The callback is called somewhere inside the getLocations method and hence its return value is not recieved inside your main function.

function reverseGeocode(latitude,longitude){
    var address = "";
    var country = "";
    var countrycode = "";
    var locality = "";

    var geocoder = new GClientGeocoder();

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

You could also consider using preparedStatement.setObject(index,value,type);

The following script emulates *nix epoch time, but it is local and regional. It should handle calender edge cases including leap years. If Cygwin is available, epoch values can be compared by specifying the Cygwin option.

I'm in EST and the difference reported is 4 hours which is relatively correct. There are some interesting solutions to remove the TZ and regional dependencies, but nothing trivial that I noticed.

@Pete Becker's answer is fine but you can also do it without passing the class instance as an explicit parameter to function1 in C++ 11:

#include <functional>
using namespace std::placeholders;

void function1(std::function<void(int, int)> fun)
{
    fun(1, 1);
}

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

   aClass a;
   auto fp = std::bind(&aClass::test, a, _1, _2);
   function1(fp);

   return 0;
}

There is one trick with ParameterBag::get() method. You can set $deep parameter to true and access the required deep nested value without extra variable:

$request->request->get('form[some][deep][data]', null, true);

Also you have possibility to set a default value (2nd parameter of get() method), it can avoid redundant isset($form['some']['deep']['data']) call.

How I did this in Swift (including the string formatting to show it as "01:23"):

let totalSeconds: Double = someTimeInterval
let minutes = Int(floor(totalSeconds / 60))
let seconds = Int(round(totalSeconds % 60))        
let timeString = String(format: "%02d:%02d", minutes, seconds)
NSLog(timeString)

Tags and Elements are not the same.

Elements

They are the pieces themselves, i.e. a paragraph is an element, or a header is an element, even the body is an element. Most elements can contain other elements, as the body element would contain header elements, paragraph elements, in fact pretty much all of the visible elements of the DOM.

Eg:

<p>This is the <span>Home</span> page</p>

Tags

Tags are not the elements themselves, rather they're the bits of text you use to tell the computer where an element begins and ends. When you 'mark up' a document, you generally don't want those extra notes that are not really part of the text to be presented to the reader. HTML borrows a technique from another language, SGML, to provide an easy way for a computer to determine which parts are "MarkUp" and which parts are the content. By using '<' and '>' as a kind of parentheses, HTML can indicate the beginning and end of a tag, i.e. the presence of '<' tells the browser 'this next bit is markup, pay attention'.

The browser sees the letters '

' and decides 'A new paragraph is starting, I'd better start a new line and maybe indent it'. Then when it sees '

- Opening tag.

One option is:

Object.keys(myObject).length

Sadly it not works under older IE versions (under 9).

If you need that compatibility, use the painful version:

var key, count = 0;
for(key in myObject) {
  if(myObject.hasOwnProperty(key)) {
    count++;
  }
}

Alternatively, by changing a line of the above code:

# df.date = df.date.apply(lambda d: datetime.strptime(d, "%Y-%m-%d"))
df.date = df.date.apply(lambda d: datetime.datetime.fromtimestamp(int(d)).strftime('%Y-%m-%d'))

It should also work.

map function in python can be used. It takes two arguments. First argument is the function which has to be used for each element of the list. Second argument is the iterable.

a = [1, 2, 3]   
map(str, a)  
['1', '2', '3']

After converting the list into string you can use simple join function to combine list into a single string

a = map(str, a)    
''.join(a)      
'123'

Solution for people who prefer clicking:

1. Install sourcetree (it is free)

2. Check how your commits look like. Most likely you have something similar to this

3. Right click on parent commit. In our case it is master branch.

4. You can squash commit with previous one by clicking a button. In our case we have to click 2 times. You can also change commit message

5. Results are awesome and we are ready to push!

Side note: If you were pushing your partial commits to remote you have to use force push after squash

I'm not sure, what you mean as the 'mobile width'. But in each case, the CSS @media can be used for hiding elements in the screen width basis. See some example:

<div id="my-content"></div>

...and:

@media screen and (min-width: 0px) and (max-width: 400px) {
  #my-content { display: block; }  /* show it on small screens */
}

@media screen and (min-width: 401px) and (max-width: 1024px) {
  #my-content { display: none; }   /* hide it elsewhere */
}

Some truly mobile detection is kind of hard programming and rather difficult. Eventually see the: http://detectmobilebrowsers.com/ or other similar sources.

   strScriptFullname = WScript.ScriptFullName 
   strScriptPath = Left(strScriptFullname, InStrRev(strScriptFullname,"\")) 

use Integer.toString(tmpInt).trim();

Try this (apply to a class you image is in (not img itself), e.g.

.myimage {
  background: transparent url("yourimage.png") no-repeat top center fixed;
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: 100%;
  height: 500px;
}

New Way: Go Modules

Since Go 1.11, you don't have to use GOPATH anymore. Simply go to your project directory and do this once:

go mod init github.com/youruser/yourrepo

• With this, Go creates a module root at that directory.
• You can create as many modules as you want.
• For step by step instructions, also see this answer.

Old Way: GOPATH

If you insist on working with GOPATH then heed this:

• Since Go 1.8, you don't need to set your GOPATH or GOROOT.
• GOPATH by default is under your user/home directory.

From the documentation:

If no GOPATH is set, it is assumed to be $HOME/go on Unix systems and %USERPROFILE%\go on Windows. If you want to use a custom location as your workspace, you can set the GOPATH environment variable.

With bash you may use read like tis:

#!/usr/bin/env bash

{ IFS= read -rd '' value <config.txt;} 2>/dev/null

printf '%s' "$value"

Notice that:

• The last newline is preserved.

• The stderr is silenced to /dev/null by redirecting the whole commands block, but the return status of the read command is preserved, if one needed to handle read error conditions.

$output = curl_exec($ch);
$result = iconv("Windows-1251", "UTF-8", $output);

This is because the current user is not permitted to write in that path. So, to change r/w (read/write) permissions you can either use 1. terminal, or 2. Graphical "Get Info" window.

1. Using Terminal

Google how to use chmod/chown (change mode/change owner) commands from terminal

2. Using graphical 'Get Info'

You can right click on the folder/file you want to change permissions of, then open Get Info which will show you a window like below at the bottom of which you can easily change r/w permissions:

Remember to change the permission back to "read only" after your temporary work, if possible

import java.util.SortedSet;
import java.util.TreeSet;

        String test2= JOptionPane.showInputDialog("Please input mark for test 2: ");

        String test3= JOptionPane.showInputDialog("Please input mark for test 3: ");

        int int1 = Integer.parseInt(test1);
        int int2 = Integer.parseInt(test2);
        int int3 = Integer.parseInt(test3);

        SortedSet<Integer> set = new TreeSet<>();
        set.add(int1);
        set.add(int2);
        set.add(int3);

        Integer [] intArray = set.toArray(new Integer[3]);
        JFrame frame = new JFrame();
        JOptionPane.showInternalMessageDialog(frame.getContentPane(), String.format("Result %f", (intArray[1] + intArray[2]) / 2.0));

    }

}

I struggled with this for a while and finally figured it out on my own. I didn't find any help at the time, but wanted to share my approach. I have done this several times and used a different method than what is above. Not sure how robust it is, but it has worked for me.

Let's say you have a textbox named "txtName", a button named "btnSave" and you want to save the name so the next time you run your program the name you typed appears in that textbox.

1. Go to Project>Properties>Settings and create a setting -

• name = "Name"
• type = "string"
• scope = "user"
• value you can leave blank.

Save your settings file.

2. Go to your form where textbox and button exist. Double click your button and put this code in;

    //This tells your program to save the value you have to the properties file (app.config);
    //"Name" here is the name you used in your settings file above.
    Properties.Settings.Default.Name = txtName.txt;
    //This tells your program to make these settings permanent, otherwise they are only
    //saved for the current session
    Properties.Settings.Default.Save();

3. Go to your form_load function and add this in there;

    //This tells your program to load the setting you saved above to the textbox
    txtName.txt = Properties.Settings.Default.Name;

4. Debug your application and you should see the name you typed in.
5. Check your application debug directory and you should see a .config file named after your program. Open that with a text editor and you will see your settings.

Notes -

• "Name" refers to the actual name of the setting you created.
• Your program will take care of creating the actual XML file, you don't have to worry about it.

This script searches for non-ascii characters in one column. It generates a string of all valid characters, here code point 32 to 127. Then it searches for rows that don't match the list:

declare @str varchar(128)
declare @i int
set @str = ''
set @i = 32
while @i <= 127
    begin
    set @str = @str + '|' + char(@i)
    set @i = @i + 1
    end

select  col1
from    YourTable
where   col1 like '%[^' + @str + ']%' escape '|'

It's an old question now, nevertheless I had the same issue and found a solution that works for me: I wrote MultiRedirectMixin.

from django.http import HttpResponseRedirect

class MultiRedirectMixin(object):
    """
    A mixin that supports submit-specific success redirection.
     Either specify one success_url, or provide dict with names of 
     submit actions given in template as keys
     Example:

         <input type="submit" name="delete" value="Delete"/>
       View:
         MyMultiSubmitView(MultiRedirectMixin, forms.FormView):
             success_urls = {"create_new": reverse_lazy('create'),
                               "delete": reverse_lazy('delete')}
    """
    success_urls = {}  

    def form_valid(self, form):
        """ Form is valid: Pick the url and redirect.
        """

        for name in self.success_urls:
            if name in form.data:
                self.success_url = self.success_urls[name]
                break

        return HttpResponseRedirect(self.get_success_url())

    def get_success_url(self):
        """
        Returns the supplied success URL.
        """
        if self.success_url:
            # Forcing possible reverse_lazy evaluation
            url = force_text(self.success_url)
        else:
            raise ImproperlyConfigured(
                _("No URL to redirect to. Provide a success_url."))
        return url

If you want to take advantage of the 60FPS smoothness that the "transform" property offers, you can combine the two:

@keyframes changewidth {
  from {
    transform: scaleX(1);
  }

  to {
    transform: scaleX(2);
  }
}

div {
  animation-duration: 0.1s;
  animation-name: changewidth;
  animation-iteration-count: infinite;
  animation-direction: alternate;
}

More explanation on why transform offers smoother transitions here: https://medium.com/outsystems-experts/how-to-achieve-60-fps-animations-with-css3-db7b98610108

You can copy-paste data from en excel-sheet to an SQL-table by doing so:

1. Select the data in Excel and press Ctrl + C
2. In SQL Server Management Studio right click the table and choose Edit Top 200 Rows
3. Scroll to the bottom and select the entire empty row by clicking on the row header
4. Paste the data by pressing Ctrl + V

Note: Often tables have a first column which is an ID-column with an auto generated/incremented ID. When you paste your data it will start inserting the leftmost selected column in Excel into the leftmost column in SSMS thus inserting data into the ID-column. To avoid that keep an empty column at the leftmost part of your selection in order to skip that column in SSMS. That will result in SSMS inserting the default data which is the auto generated ID. Furthermore you can skip other columns by having empty columns at the same ordinal positions in the Excel sheet selection as those columns to be skipped. That will make SSMS insert the default value (or NULL where no default value is specified).

In my case I was using a native DLL in C#. This DLL depended on couple of other DLLs that were missing. Once those other DLLs were added everything worked.

An enumerated type is basically a data type that lets you describe each member of a type in a more readable and reliable way.

Here is a simple example to explain why:

Assuming you are writing a method that has something to do with seasons:

The int enum pattern

First, you declared some int static constants to represent each season.

public static final int SPRING = 0;
public static final int SUMMER = 1;
public static final int FALL = 2;
public static final int WINTER = 2;

Then, you declared a method to print name of the season into the console.

public void printSeason(int seasonCode) {
    String name = "";
    if (seasonCode == SPRING) {
        name = "Spring";
    }
    else if (seasonCode == SUMMER) {
        name = "Summer";
    }
    else if (seasonCode == FALL) {
        name = "Fall";
    }
    else if (seasonCode == WINTER) {
        name = "Winter";
    }
    System.out.println("It is " + name + " now!");
}

So, after that, you can print a season name like this.

printSeason(SPRING);
printSeason(WINTER);

This is a pretty common (but bad) way to do different things for different types of members in a class. However, since these code involves integers, so you can also call the method like this without any problems.

printSeason(0);
printSeason(1);

or even like this

printSeason(x - y);
printSeason(10000);

The compiler will not complain because these method calls are valid, and your printSeason method can still work.

But something is not right here. What does a season code of 10000 supposed to mean? What if x - y results in a negative number? When your method receives an input that has no meaning and is not supposed to be there, your program knows nothing about it.

You can fix this problem, for example, by adding an additional check.

...
else if (seasonCode == WINTER) {
    name = "Winter";
}
else {
    throw new IllegalArgumentException();
}
System.out.println(name);

Now the program will throw a RunTimeException when the season code is invalid. However, you still need to decide how you are going to handle the exception.

By the way, I am sure you noticed the code of FALL and WINTER are both 2, right?

You should get the idea now. This pattern is brittle. It makes you write condition checks everywhere. If you're making a game, and you want to add an extra season into your imaginary world, this pattern will make you go though all the methods that do things by season, and in most case you will forget some of them.

You might think class inheritance is a good idea for this case. But we just need some of them and no more.

That's when enum comes into play.

Use enum type

In Java, enum types are classes that export one instance for each enumeration constant via a public static final field.

Here you can declare four enumeration constants: SPRING, SUMMER, FALL, WINTER. Each has its own name.

public enum Season {
    SPRING("Spring"), SUMMER("Summer"), FALL("Fall"), WINTER("Winter");

    private String name;

    Season(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

Now, back to the method.

public void printSeason(Season season) {
    System.out.println("It is " + season.getName() + " now!");
}

Instead of using int, you can now use Season as input. Instead of a condition check, you can tell Season to give you its name.

This is how you use this method now:

printSeason(Season.SPRING);
printSeason(Season.WINTER);
printSeason(Season.WHATEVER); <-- compile error

You will get a compile-time error when you use an incorrect input, and you're guaranteed to get a non-null singleton reference of Season as long as the program compiles.

When we need an additional season, we simply add another constant in Season and no more.

public enum Season {
    SPRING("Spring"), SUMMER("Summer"), FALL("Fall"), WINTER("Winter"), 
    MYSEASON("My Season");

...

Whenever you need a fixed set of constants, enum can be a good choice (but not always). It's a more readable, more reliable and more powerful solution.

You can try this

String text = "ddd123.0114cc";
    String numOnly = text.replaceAll("\\p{Alpha}","");
    try {
        double numVal = Double.valueOf(numOnly);
        System.out.println(text +" contains numbers");
    } catch (NumberFormatException e){
        System.out.println(text+" not contains numbers");
    }     

This is a bit of an open ended question since screen sizes are changing all the time and what might have been correct two years ago would likely be out of date now.

I use Twitter Bootstrap 3 at present and it uses a fluid grid system designed to work at sizes ranging from mobile/very small all the way up to the huge wide screen monitors that are now available.

Currently the upper default in BS3 is 1200px which translates to a container width of 1144px after taking account of margins and padding of the grids elements.

In my experience, modern designers are working to a width of around 1366px for desktop. All recent designs I've been given to implement have been 1366px.

Note also that you can customise the BS3 grid quite heavily. For example we will use a 32 column grid with 4px gutter in our sites/designs going forwards.

Ultimately the decision on page width needs to be made based on your website analytics and the screen sizes that your visitors typically use.

You can use Async - Await:

async function axiosTest() {
  const response = await axios.get(url);
  const data = await response.json();  
}

Please don't throw stones at me for this solution.

This works but is a bit "hacky".

When you call requestPermissions, register the current time.

        mAskedPermissionTime = System.currentTimeMillis();

Then in onRequestPermissionsResult

if the result is not granted, check the time again.

 if (System.currentTimeMillis() - mAskedPermissionTime < 100)

Since the user did cannot possibly click so fast on the deny button, we know that he selected "never ask again" because the callback is instant.

Use at your own risks.

if (position ==0) {
    if (rYes.isChecked()) {
        Toast.makeText(SportActivity.this, "yes ur answer is right", Toast.LENGTH_LONG).show();
    } else if (rNo.isChecked()) {
        Toast.makeText(SportActivity.this, "no.ur answer is wrong", Toast.LENGTH_LONG).show();
    }
}

This code is supposed to select both check boxes.
Is there a problem with it?

Try the following. It is working:

echo("<script>console.log('PHP: " . $data . "');</script>");

You are setting the response headers after writing the contents of the file to the output stream. This is quite late in the response lifecycle to be setting headers. The correct sequence of operations should be to set the headers first, and then write the contents of the file to the servlet's outputstream.

Therefore, your method should be written as follows (this won't compile as it is a mere representation):

response.setContentType("application/force-download");
response.setContentLength((int)f.length());
        //response.setContentLength(-1);
response.setHeader("Content-Transfer-Encoding", "binary");
response.setHeader("Content-Disposition","attachment; filename=\"" + "xxx\"");//fileName);
...
...
File f= new File(fileName);

InputStream in = new FileInputStream(f);
BufferedInputStream bin = new BufferedInputStream(in);
DataInputStream din = new DataInputStream(bin);

while(din.available() > 0){
    out.print(din.readLine());
    out.print("\n");
}

The reason for the failure is that it is possible for the actual headers sent by the servlet would be different from what you are intending to send. After all, if the servlet container does not know what headers (which appear before the body in the HTTP response), then it may set appropriate headers to ensure that the response is valid; setting the headers after the file has been written is therefore futile and redundant as the container might have already set the headers. You could confirm this by looking at the network traffic using Wireshark or a HTTP debugging proxy like Fiddler or WebScarab.

You may also refer to the Java EE API documentation for ServletResponse.setContentType to understand this behavior:

Sets the content type of the response being sent to the client, if the response has not been committed yet. The given content type may include a character encoding specification, for example, text/html;charset=UTF-8. The response's character encoding is only set from the given content type if this method is called before getWriter is called.

This method may be called repeatedly to change content type and character encoding. This method has no effect if called after the response has been committed.

I found a solution on another thread that works - use the pull-left class:

 <a href="#" class="pull-left"><img src="/path/to/image.png"></a>

I think you haven't messed up yet. Try:

git reset HEAD^

This will bring the dir to state before you've made the commit, HEAD^ means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).

Just a comment on this - I've used HTML5 video for a full-screen background and it works a treat - but make sure to use either Height:100% and width:auto or the other way around - to ensure you keep aspect ratio.

As for Ipads -you can (apparently) do this, by having a hidden and then forcing the click event to fire, and having the function of the click event kick off the Load/Play().

P.s - this shouldn't require any plugins and can be done with minimal JS - If you're targeting any mobile device (I would assume you might be..) staying away from any such framework is the way forward.

If you want to add wsdl reference in .Net Core project, there is no "Add web reference" option.

To add the wsdl reference go to Solution Explorer, right-click on the References project item and then click on the Add Connected Service option.

Then click 'Microsoft WCF Web Service Reference':

Enter the file path into URI text box and import the WSDL:

It will generate a simple, very basic WCF client and you to use it something like this:

YourServiceClient client = new YourServiceClient();
client.DoSomething();

I think you should casting variable or use Integer class by call out method doubleValue().

Javascript using the onLoad() event, will wait for the page to be loaded before executing.

<body onload="somecode();" >

If you're using the jQuery framework's document ready function the code will load as soon as the DOM is loaded and before the page contents are loaded:

$(document).ready(function() {
    // jQuery code goes here
});

Use the \ character to escape a character that has special meaning inside a regular expression.

To automate it, you could use this:

function escapeRegExp(text) {
  return text.replace(/[-[\]{}()*+?.,\\^$|#\s]/g, '\\$&');
}

Update: There is now a proposal to standardize this method, possibly in ES2016: https://github.com/benjamingr/RegExp.escape

Update: The abovementioned proposal was rejected, so keep implementing this yourself if you need it.

To solve the issue you must assign the proper ownership permissions. Try the below which should resolve all permission related issues for specific users but as stated in the comments this should not be used in production:

root@server:/var/log/postgresql# sudo -u postgres psql
psql (8.4.4)
Type "help" for help.

postgres=# \du
               List of roles
    Role name    | Attributes  | Member of
-----------------+-------------+-----------
 <user-name>    | Superuser   | {}
                 : Create DB
 postgres       | Superuser   | {}
                 : Create role
                 : Create DB

postgres=# alter role <user-name> superuser;
ALTER ROLE
postgres=#

So connect to the database under a Superuser account sudo -u postgres psql and execute a ALTER ROLE <user-name> Superuser; statement.

Keep in mind this is not the best solution on multi-site hosting server so take a look at assigning individual roles instead: https://www.postgresql.org/docs/current/static/sql-set-role.html and https://www.postgresql.org/docs/current/static/sql-alterrole.html.

SELECT *

RollingFileAppender does this. You just need to set maxBackupIndex to the highest value for the backup file.

HTTPS is so powerful because it uses asymmetric cryptography. This type of cryptography not only allows you to create an encrypted tunnel but you can verify that you are talking to the right person, and not a hacker.

Here is Java source code which uses the asymmetric cipher RSA (used by PGP) to communicate: http://www.hushmail.com/services/downloads/

First you need to add column for auto increment

alter table users add column id int(5) NOT NULL AUTO_INCREMENT FIRST

This query for add column at first. Now you have to reset auto increment initial value. So use this query

alter table users AUTO_INCREMENT=1001

Now your table started with 1001

This simply means that something in the backend ( DBMS ) decided to stop working due to unavailability of resources etc. It has nothing to do with your code or the number of inserts. You can read more about similar problems here:

This may not answer your question, but you will get an idea of why it might be happening. You could further discuss with your DBA and see if there is something specific in your case.

The first URL gives a HTTP 302 (temporary redirect) to the second. So, to find the second URL programatically, you could issue a HTTP request for the first URL and get the Location header of the response.

That said, don't rely on the second URL being pemanent. Reading a little in to the HTTP response code (of 302 as opposed to a permanent 301), it is possible Facebook changes those URLs on a regular basis to prevent people from—for example—using their servers to host images.

Edit: Notice that the CDN URL the OP posted is now a 404, so we know that we cannot rely on the URL being long-lived. Also, if you're linking to the Graph API from an <img> on a SSL-secured page, there's a parameter you have to add make sure you use https://graph.facebook.com.

Update: The API has added a parameter – redirect=false – which causes JSON to be returned rather than a redirect. The retruned JSON includes the CDN URL:

{
   "data": {
      "url": "http://profile.ak.fbcdn.net/...",
      "is_silhouette": false
   }
}

Again, I wouldn't rely on this CDN URL being long-lived. The JSON response is sent with permissive CORS headers, so you're free to do this client-side with XHR requests.

This will have the field take 50% of the width and be centered and resized properly

    {    
        width: 50%;
        margin-left : 25%
    }

May also use "vw" (view width) units instead of "%"

It's O(V+E) because each visit to v of V must visit each e of E where |e| <= V-1. Since there are V visits to v of V then that is O(V). Now you have to add V * |e| = E => O(E). So total time complexity is O(V + E).

try

$('#select_all').click( function() {
    $('#countries option').each(function(){
        $(this).attr('selected', 'selected');
    });
});

this will give you more scope in the future to write things like

$('#select_all').click( function() {
    $('#countries option').each(function(){
        if($(this).attr('something') != 'omit parameter')
        {
            $(this).attr('selected', 'selected');
        }
    });
});

Basically allows for you to do a select all EU members or something if required later down the line

Once you have obtained the context in your onTap() you can also do:

Intent myIntent = new Intent(mContext, theNewActivity.class);
mContext.startActivity(myIntent);

var input = "12342";
var output = input.Substring(0, input.Length - 1); 

or

var output = input.Remove(input.Length - 1);

You can make the file usable as a script as well as an importable module.

fibo.py (a module named fibo)

# Other modules can IMPORT this MODULE to use the function fib
def fib(n):    # write Fibonacci series up to n
    a, b = 0, 1
    while b < n:
        print(b, end=' ')
        a, b = b, a+b
    print()

# This allows the file to be used as a SCRIPT
if __name__ == "__main__":
    import sys
    fib(int(sys.argv[1]))

You can use the IsNullOrEmpty static method:

Something like this in your form main. Double click the form in the visual editor to create the form load event.

 Timer Clock=new Timer();
 Clock.Interval=2700000; // not sure if this length of time will work 
 Clock.Start();
 Clock.Tick+=new EventHandler(Timer_Tick);

Then add an event handler to do something when the timer fires.

  public void Timer_Tick(object sender,EventArgs eArgs)
  {
    if(sender==Clock)
    {
      // do something here      
    }
  }

To install all currently supported python versions (python 3.6 is already pre-installed) including pip for Ubuntu 18.04 do the following:

To install python3.5 and python3.7, use the deadsnakes ppa:

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.5
sudo apt-get install python3.7

Install python2.7 via distribution packages:

sudo apt install python-minimal  # on Ubuntu 18.04 python-minimal maps to python2.7

To install pip use:

sudo apt install python-pip  # on Ubuntu 18.04 this refers to pip for python2.7
sudo apt install python3-pip  # on Ubuntu 18.04 this refers to pip for python3.6
python3.5 -m pip install pip # this will install pip only for the current user
python3.7 -m pip install pip

I used it for setting up a CI-chain for a python project with tox and Jenkins.

You need to do the following

git fetch -p

in order to synchronize your branch list. The git manual says

-p, --prune
After fetching, remove any remote-tracking references that no longer exist on the remote. Tags are not subject to pruning if they are fetched only because of the default tag auto-following or due to a --tags option. However, if tags are fetched due to an explicit refspec (either on the command line or in the remote configuration, for example if the remote was cloned with the --mirror option), then they are also subject to pruning.

I personally like to use git fetch origin -p --progress because it shows a progress indicator.

First off, custom events don't play well with React components natively. So you cant just say <div onMyCustomEvent={something}> in the render function, and have to think around the problem.

Secondly, after taking a peek at the documentation for the library you're using, the event is actually fired on document.body, so even if it did work, your event handler would never trigger.

Instead, inside componentDidMount somewhere in your application, you can listen to nv-enter by adding

document.body.addEventListener('nv-enter', function (event) {
    // logic
});

Then, inside the callback function, hit a function that changes the state of the component, or whatever you want to do.

If Nothing Helps then it means Device Guard and Credential Guard are using the virtualization. I had to disable them by downloading and running the following script from microsoft site.

Once you do it, you need to restart and confirm disable both when asked just before boot.

stopPropagation prevents further propagation of the current event in the capturing and bubbling phases.

preventDefault prevents the default action the browser makes on that event.

Examples

preventDefault

$("#but").click(function (event) {
  event.preventDefault()
})
$("#foo").click(function () {
  alert("parent click event fired!")
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="foo">
  <button id="but">button</button>
</div>

stopPropagation

$("#but").click(function (event) {
  event.stopPropagation()
})
$("#foo").click(function () {
  alert("parent click event fired!")
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="foo">
  <button id="but">button</button>
</div>

With stopPropagation, only the button's click handler is called while the div's click handler never fires.

Where as if you use preventDefault, only the browser's default action is stopped but the div's click handler still fires.

Below are some docs on the DOM event properties and methods from MDN:

• event.cancelBubble
• event.preventDefault()
• event.returnValue
• event.stopPropagation()

For IE9 and FF you can just use preventDefault & stopPropagation.

To support IE8 and lower replace stopPropagation with cancelBubble and replace preventDefault with returnValue

In case you're using git, use the right email address you used for github registration and then your computer name. this worked for me.

Here is what you can do if you want to add a column of numbers in Excel. ( I am using Excel 2010 but should not make a difference.)

Example: Lets say you want to add the cells in Column B form B10 to B100 & want the answer to be in cell X or be Variable X ( X can be any cell or any variable you create such as Dim X as integer, etc). Here is the code:

Range("B5") = "=SUM(B10:B100)"

or

X = "=SUM(B10:B100)

There are no quotation marks inside the parentheses in "=Sum(B10:B100) but there are quotation marks inside the parentheses in Range("B5"). Also there is a space between the equals sign and the quotation to the right of it.

It will not matter if some cells are empty, it will simply see them as containing zeros!

This should do it for you!

Only add Any iOS Simulator SDK -> x86_64 to Project's Build Settings -> VALID_ARCHS works for me.

Xcode version: 12.1 (12A7403)

If your project includes some frameworks that don't support x86_64.

• You can add these framework names(xxx.framework) to Target -> Build Settings -> Excluded Source File Names -> Debug -> Any iOS Simulator SDK.
• And then modify the Framework Search Paths to delete the paths of these frameworks for Debug -> Any iOS Simulator SDK.

These two settings can avoid Xcode to build and link these frameworks on simulator mode.

If you are using Fresco, you can use this -

final ImageRequest imageRequest = ImageRequestBuilder.newBuilderWithSource(uri)
.setRotationOptions(RotationOptions.autoRotate())
.build();

mSimpleDraweeView.setController(
Fresco.newDraweeControllerBuilder()
    .setImageRequest(imageRequest)
    .build());

This automatically rotates the images based on Exif data.

I was looking for something like this and after some tries and falls i create my own makefile, I know that's not the "idiomatic way" but it's a begining to understand make and this works for me, maybe you could try in your project.

I like atn's answer, but it was not as trivial for me to download as wintee, which is also open source and only gives the tee functionality (useful if you just want tee and not the entire set of unix utilities). I learned about this from davor's answer to Displaying Windows command prompt output and redirecting it to a file, where you also find reference to the unix utilities.

From Xcode 9 and on you can take screenshot or record Video using simctl binary that you can find it here:

/Applications/Xcode.app/Contents/Developer/usr/bin/simctl

You can use it with xcrun to command the simulator in the command line.

1. For taking screenshot run this in command line:

   xcrun simctl io booted screenshot
   

2. For recording video on the simulator using command line:

   xcrun simctl io booted recordVideo fileName.videoType(e.g mp4/mov)
   

Note: You can use this command in any directory of your choice. The file will be saved in that directory.

I think this is similar to what the last podcast discussed. The "Be liberal in what you accept" means that extra work had to be put into the Javascript parser to fix cases where semicolons were left out. Now we have a boatload of pages out there floating around with bad syntax, that might break one day in the future when some browser decides to be a little more stringent on what it accepts. This type of rule should also apply to HTML and CSS. You can write broken HTML and CSS, but don't be surprise when you get weird and hard to debug behaviors when some browser doesn't properly interpret your incorrect code.

I have a wrapper script called provision forces you to choose the target, so I don't have to handle it elsewhere.

For those that are curious, I use ENV vars for options that my vagrantfile uses (adding the corresponding ansible arg for cloud systems) and let the rest of the ansible args pass through. Where I am creating and provisioning more than 10 servers at a time I include an auto retry on failed servers (as long as progress is being made - I found when creating 100 or so servers at a time often a few would fail the first time around).

echo 'Usage: [VAR=value] bin/provision [options] dev|all|TARGET|vagrant'
echo '  bootstrap - Bootstrap servers ssh port and initial security provisioning'
echo '  dev - Provision localhost for development and control'
echo '  TARGET - specify specific host or group of hosts'
echo '  all - provision all servers'
echo '  vagrant - Provision local vagrant machine (environment vars only)'
echo
echo 'Environment VARS'
echo '  BOOTSTRAP - use cloud providers default user settings if set'
echo '  TAGS - if TAGS env variable is set, then only tasks with these tags are run'
echo '  SKIP_TAGS - only run plays and tasks whose tags do not match these values'
echo '  START_AT_TASK - start the playbook at the task matching this name'
echo
ansible-playbook --help | sed -e '1d
    s#=/etc/ansible/hosts# set by bin/provision argument#
    /-k/s/$/ (use for fresh systems)/
    /--tags/s/$/ (use TAGS var instead)/
    /--skip-tags/s/$/ (use SKIP_TAGS var instead)/
    /--start-at-task/s/$/ (use START_AT_TASK var instead)/

A CRLF is two characters, of course, the CR and the LF. However, `n consists of both. For example:

PS C:\> $x = "Hello
>> World"

PS C:\> $x
Hello
World
PS C:\> $x.contains("`n")
True
PS C:\> $x.contains("`r")
False
PS C:\> $x.replace("o`nW","o There`nThe W")
Hello There
The World
PS C:\>

I think you're running into problems with the `r. I was able to remove the `r from your example, use only `n, and it worked. Of course, I don't know exactly how you generated the original string so I don't know what's in there.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

You can use the set() function to convert an iterable into a set, and then use standard set update operator (|=) to add the unique values from your new set into the existing one.

>>> a = { 1, 2, 3 }
>>> b = ( 3, 4, 5 )
>>> a |= set(b)
>>> a
set([1, 2, 3, 4, 5])

NoneType is simply the type of the None singleton:

>>> type(None)
<type 'NoneType'>

From the latter link above:

None

The sole value of the type NoneType. None is frequently used to represent the absence of a value, as when default arguments are not passed to a function. Assignments to None are illegal and raise a SyntaxError.

In your case, it looks like one of the items you are trying to concatenate is None, hence your error.

You can also use the "custom options" support from the request library. This format allows you to create a multi-part form upload, but with a combined entry for both the file and extra form information, like filename or content-type. I have found that some libraries expect to receive file uploads using this format, specifically libraries like multer.

This approach is officially documented in the forms section of the request docs - https://github.com/request/request#forms

//toUpload is the name of the input file: <input type="file" name="toUpload">

let fileToUpload = req.file;

let formData = {
    toUpload: {
      value: fs.createReadStream(path.join(__dirname, '..', '..','upload', fileToUpload.filename)),
      options: {
        filename: fileToUpload.originalname,
        contentType: fileToUpload.mimeType
      }
    }
  };
let options = {
    url: url,
    method: 'POST',
    formData: formData
  }
request(options, function (err, resp, body) {
    if (err)
      cb(err);

    if (!err && resp.statusCode == 200) {
      cb(null, body);
    }
  });

Alternatively you can create a new scope and pass through params via the scope option

var scope = $rootScope.$new();
 scope.params = {editId: $scope.editId};
    $modal.open({
        scope: scope,
        templateUrl: 'template.html',
        controller: 'Controller',
    });

In your modal controller pass in $scope, you then do not need to pass in and itemsProvider or what ever resolve you named it

modalController = function($scope) {
    console.log($scope.params)
}

You could try:

.modal.modal-wide .modal-dialog {
  width: 90%;
}

.modal-wide .modal-body {
  overflow-y: auto;
}

Just add .modal-wide to your classes

Feb, 2016:

I needed to do this based on client entered database values and without a lat/long generator. Google really likes lat/long these days. Here is what I learned:

1 The beginning of the link looks like this: https://www.google.com/maps/place/

2 Then you put your address:

• Use a + instead of any space.
• Put a comma , in front and behind the city.
• Include the postal/zip and the province/state.
• Replace any # with nothing.
• Replace any ++ or ++++ with single +

3 Put the address after the place/

4 Then put a slash at the end.

NOTE: The slash at the end was important. After the user clicks the link, Google goes ahead and appends more to the URL and they do it after this slash.

Working example for this question:

https://www.google.ca/maps/place/1200+Pennsylvania+Ave+SE,+Washington,+DC+20003/

I hope that helps.

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

I used lobos answer and it works. But I had a problem with the conversion of doubles because of the culture settings. So I added

return (T)Convert.ChangeType(base.Value, typeof(T), CultureInfo.InvariantCulture);

You can use the following CSS to style the input element.

input[type="date"] {_x000D_
  background-color: red;_x000D_
  outline: none;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-clear-button {_x000D_
  font-size: 18px;_x000D_
  height: 30px;_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-inner-spin-button {_x000D_
  height: 28px;_x000D_
}_x000D_
_x000D_
input[type="date"]::-webkit-calendar-picker-indicator {_x000D_
  font-size: 15px;_x000D_
}

<input type="date" value="From" name="from" placeholder="From" required="" />

For Angular 2 and newer, the easiest way to add no-cache headers by overriding RequestOptions:

import { Injectable } from '@angular/core';
import { BaseRequestOptions, Headers } from '@angular/http';

@Injectable()
export class CustomRequestOptions extends BaseRequestOptions {
    headers = new Headers({
        'Cache-Control': 'no-cache',
        'Pragma': 'no-cache',
        'Expires': 'Sat, 01 Jan 2000 00:00:00 GMT'
    });
}

And reference it in your module:

@NgModule({
    ...
    providers: [
        ...
        { provide: RequestOptions, useClass: CustomRequestOptions }
    ]
})

You can't restart a thread so your best option is to save the current state of the object at the time the thread was stopped and when operations need to continue on that object you can recreate that object using the saved and then start the new thread.

These two articles Swing Worker and Concurrency may help you determine the best solution for your problem.

Based on various answers on Stack Overflow and blogs I've come across, this is the method I'm using, and it seems to return real words quite well. The idea is to split the incoming text into an array of words (use whichever method you'd like), and then find the parts of speech (POS) for those words and use that to help stem and lemmatize the words.

You're sample above doesn't work too well, because the POS can't be determined. However, if we use a real sentence, things work much better.

import nltk
from nltk.corpus import wordnet

lmtzr = nltk.WordNetLemmatizer().lemmatize


def get_wordnet_pos(treebank_tag):
    if treebank_tag.startswith('J'):
        return wordnet.ADJ
    elif treebank_tag.startswith('V'):
        return wordnet.VERB
    elif treebank_tag.startswith('N'):
        return wordnet.NOUN
    elif treebank_tag.startswith('R'):
        return wordnet.ADV
    else:
        return wordnet.NOUN


def normalize_text(text):
    word_pos = nltk.pos_tag(nltk.word_tokenize(text))
    lemm_words = [lmtzr(sw[0], get_wordnet_pos(sw[1])) for sw in word_pos]

    return [x.lower() for x in lemm_words]

print(normalize_text('cats running ran cactus cactuses cacti community communities'))
# ['cat', 'run', 'ran', 'cactus', 'cactuses', 'cacti', 'community', 'community']

print(normalize_text('The cactus ran to the community to see the cats running around cacti between communities.'))
# ['the', 'cactus', 'run', 'to', 'the', 'community', 'to', 'see', 'the', 'cat', 'run', 'around', 'cactus', 'between', 'community', '.']

You are getting this error: "React Hook "useState" is called in function "App" which is neither a React function component or a custom React Hook function"

Solution: You basically need to Capitalize the function.

For example:

const Helper =()=>{}_x000D_
_x000D_
function Helper2(){}

I didn't like the idea of creating a custom component, because if you have a different wrapping element you would have to create another custom component etc. Also, it is just overkill. So I just did it with css and activeClassName:

<li className="link-wrapper">  <!-- add a class to the wrapper -->
  <Link to="something" activeClassName="active">Something</Link>
</li>

And then just add some css:

li.link-wrapper > a.active {
    display: block;
    width: 100%;
    height:100%;
    color: white;
    background-color: blue;
}

Technically this doesn't style the li, but it makes the anchor fill the li and styles it.

You don't "commit the folder" - you add the folder, as you have done, and then simply commit all changes. The command should be:

git add foldername
git commit -m "commit operation"

A decent way to check whether there is an issue in your certificate chain is to use this website:

https://www.digicert.com/help/

Plug in your test URL and it will tell you what may be wrong. We had an issue with the same symptom as you, and our issue was diagnosed as being due to intermediate certificates.

SSL Certificate is not trusted

The certificate is not signed by a trusted authority (checking against Mozilla's root store). If you bought the certificate from a trusted authority, you probably just need to install one or more Intermediate certificates. Contact your certificate provider for assistance doing this for your server platform.

This worked me for UNICODE (UTF8) sentences too:

function myUTF8truncate($string, $width){
    if (mb_str_word_count($string) > $width) {
        $string= preg_replace('/((\w+\W*|| [\p{L}]+\W*){'.($width-1).'}(\w+))(.*)/', '${1}', $string);
    }
    return $string;
}

#include <iostream>
#include <sstream>
#include <vector>
using namespace std;

int main() {

    string s1="split on     whitespace";
    istringstream iss(s1);
    vector<string> result;
    for(string s;iss>>s;)
        result.push_back(s);
    int n=result.size();
    for(int i=0;i<n;i++)
        cout<<result[i]<<endl;
    return 0;
}

Output:-

split
on
whitespace

Using String format will help but you must be care full with the locale. In germany float will be separates with in comma instead an point.

Using String.format("geo:%f,%f",5.1,2.1); on locale english the result will be "geo:5.1,2.1" but with locale german you will get "geo:5,1,2,1"

You should use the English locale to prevent this behavior.

String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

To set an label to the geo point you can extend your geo uri by using:

!!! but be carefull with this the geo-uri is still under develoment http://tools.ietf.org/html/draft-mayrhofer-geo-uri-00

String uri = String.format(Locale.ENGLISH, "geo:%f,%f?z=%d&q=%f,%f (%s)", 
                           latitude, longitude, zoom, latitude, longitude, label);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

I ran into the same difficulty. The code below should work for positive integers.

I haven't compiled it yet but I tested the algorithm on a google spreadsheet (I know, wtf) and it was working.

unsigned int integer_div_round_nearest(unsigned int numerator, unsigned int denominator)
{
    unsigned int rem;
    unsigned int floor;
    unsigned int denom_div_2;

    // check error cases
    if(denominator == 0)
        return 0;

    if(denominator == 1)
        return numerator;

    // Compute integer division and remainder
    floor = numerator/denominator;
    rem = numerator%denominator;

    // Get the rounded value of the denominator divided by two
    denom_div_2 = denominator/2;
    if(denominator%2)
        denom_div_2++;

    // If the remainder is bigger than half of the denominator, adjust value
    if(rem >= denom_div_2)
        return floor+1;
    else
        return floor;
}

For anyone using entity framework core ending up here. This is how you do it.

# Powershell / Package manager console
Script-Migration

# Cli 
dotnet ef migrations script

You can use the -From and -To parameter to generate an update script to update a database to a specific version.

Script-Migration -From 20190101011200_Initial-Migration -To 20190101021200_Migration-2

https://docs.microsoft.com/en-us/ef/core/managing-schemas/migrations/#generate-sql-scripts

There are several options to this command.

The from migration should be the last migration applied to the database before running the script. If no migrations have been applied, specify 0 (this is the default).

The to migration is the last migration that will be applied to the database after running the script. This defaults to the last migration in your project.

An idempotent script can optionally be generated. This script only applies migrations if they haven't already been applied to the database. This is useful if you don't exactly know what the last migration applied to the database was or if you are deploying to multiple databases that may each be at a different migration.

I just had a very similar issues with gradle builds / adding .jar library. I got it working by a combination of :

1. Moving the libs folder up to the root of the project (same directory as 'src'), and adding the library to this folder in finder (using Mac OS X)
2. In Android Studio, Right-clicking on the folder to add as library
3. Editing the dependencies in the build.gradle file, adding compile fileTree(dir: 'libs', include: '*.jar')}

BUT more importantly and annoyingly, only hours after I get it working, Android Studio have just released 0.3.7, which claims to have solved a lot of gradle issues such as adding .jar libraries

Hope this helps people!

using JQuery:

myelement=$("#myelement")
[myelement.offset().left, myelement.offset().top,  myelement.width(), myelement.height()]

It's better to use $(window).scroll() rather than $('#Eframe').on("mousewheel")

$('#Eframe').on("mousewheel") will not trigger if people manually scroll using up and down arrows on the scroll bar or grabbing and dragging the scroll bar itself.

$(window).scroll(function(){
    var scrollPos = $(document).scrollTop();
    console.log(scrollPos);
});

If #Eframe is an element with overflow:scroll on it and you want it's scroll position. I think this should work (I haven't tested it though).

$('#Eframe').scroll(function(){
    var scrollPos = $('#Eframe').scrollTop();
    console.log(scrollPos);
});

I had the same problem when trying to deploy, tomcat failed to restart as Tomcat instance was running. Close the IDE and check TASk Manager - kill any javaw process running, that solved the problem for me.

sprintf( cmd, "/bin/cp -p \'%s\' \'%s\'", old, new);

system( cmd);

Add some error checks...

Otherwise, open both and loop on read/write, but probably not what you want.

...

UPDATE to address valid security concerns:

Rather than using "system()", do a fork/wait, and call execv() or execl() in the child.

execl( "/bin/cp", "-p", old, new);

Use Entry.insert. For example:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
e = Entry(root)
e.insert(END, 'default text')
e.pack()
root.mainloop()

Or use textvariable option:

try:
    from tkinter import *  # Python 3.x
except Import Error:
    from Tkinter import *  # Python 2.x

root = Tk()
v = StringVar(root, value='default text')
e = Entry(root, textvariable=v)
e.pack()
root.mainloop()

Here is a code snippet taken from a blog article written by Anubhav Goyal:

// this code will mark the forms authentication cookie and the
// session cookie as Secure.
if (Response.Cookies.Count > 0)
{
    foreach (string s in Response.Cookies.AllKeys)
    {
        if (s == FormsAuthentication.FormsCookieName || "asp.net_sessionid".Equals(s, StringComparison.InvariantCultureIgnoreCase))
        {
             Response.Cookies[s].Secure = true;
        }
    }
}

Adding this to the EndRequest event handler in the global.asax should make this happen for all page calls.

Note: An edit was proposed to add a break; statement inside a successful "secure" assignment. I've rejected this edit based on the idea that it would only allow 1 of the cookies to be forced to secure and the second would be ignored. It is not inconceivable to add a counter or some other metric to determine that both have been secured and to break at that point.

Good news! Snappy!!

Snappy is a very easy open source PHP5 library, allowing thumbnail, snapshot or PDF generation from a url or a html page. And... it uses the excellent webkit-based wkhtmltopdf

Enjoy! ^_^

There's another, very secure method. It's client certificates. Know how servers present an SSL Cert when you contact them on https? Well servers can request a cert from a client so they know the client is who they say they are. Clients generate certs and give them to you over a secure channel (like coming into your office with a USB key - preferably a non-trojaned USB key).

You load the public key of the cert client certificates (and their signer's certificate(s), if necessary) into your web server, and the web server won't accept connections from anyone except the people who have the corresponding private keys for the certs it knows about. It runs on the HTTPS layer, so you may even be able to completely skip application-level authentication like OAuth (depending on your requirements). You can abstract a layer away and create a local Certificate Authority and sign Cert Requests from clients, allowing you to skip the 'make them come into the office' and 'load certs onto the server' steps.

Pain the neck? Absolutely. Good for everything? Nope. Very secure? Yup.

It does rely on clients keeping their certificates safe however (they can't post their private keys online), and it's usually used when you sell a service to clients rather then letting anyone register and connect.

Anyway, it may not be the solution you're looking for (it probably isn't to be honest), but it's another option.

To search in current directory recursively:

grep -r 'myString' .

This can be done in three steps:

// 1. Read the content of the file
string[] readText = File.ReadAllLines(path);

// 2. Empty the file
File.WriteAllText(path, String.Empty);

// 3. Fill up again, but without the deleted line
using (StreamWriter writer = new StreamWriter(path))
{
    foreach (string s in readText)
    {
        if (!s.Equals(lineToBeRemoved))
        {
            writer.WriteLine(s);
        }
    }
}

There are references to the official docs (DialogFragment Reference) in other answers, but no mention of the example given there:

void showDialog() {
    mStackLevel++;

    // DialogFragment.show() will take care of adding the fragment
    // in a transaction.  We also want to remove any currently showing
    // dialog, so make our own transaction and take care of that here.
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    Fragment prev = getFragmentManager().findFragmentByTag("dialog");
    if (prev != null) {
        ft.remove(prev);
    }
    ft.addToBackStack(null);

    // Create and show the dialog.
    DialogFragment newFragment = MyDialogFragment.newInstance(mStackLevel);
    newFragment.show(ft, "dialog");
}

This removes any currently shown dialog, creates a new DialogFragment with an argument, and shows it as a new state on the back stack. When the transaction is popped, the current DialogFragment and its Dialog will be destroyed, and the previous one (if any) re-shown. Note that in this case DialogFragment will take care of popping the transaction of the Dialog is dismissed separately from it.

For my needs I changed it to:

FragmentManager manager = getSupportFragmentManager();
Fragment prev = manager.findFragmentByTag(TAG);
if (prev != null) {
    manager.beginTransaction().remove(prev).commit();
}

MyDialogFragment fragment = new MyDialogFragment();
fragment.show(manager, TAG);

If you happen to have both a bash shell and jad:

JAR=(your jar file name)
unzip -d $JAR.tmp $JAR
pushd $JAR.tmp
for f in `find . -name '*.class'`; do
    jad -d $(dirname $f) -s java -lnc $f
done
popd

I might be a tiny, tiny bit off with that, but it should work more or less as advertised. You should end up with $JAR.tmp containing your decompiled files.

You might also want to check out Tie::IxHash, which implements ordered associative arrays. That would allow you to do both types of lookups (hash and index) on one copy of your data.

If you want using it with parameter (ie. delete all subdirs under the given directory), then put this two lines into a *.bat or *.cmd file:

@echo off
for /f "delims=" %%d in ('dir %1 /s /b /ad ^| sort /r') do rd "%%d" 2>nul && echo rmdir %%d

and add script-path to your PATH environment variable. In this case you can call your batch file from any location (I suppose UNC path should work, too).

Eg.:

YourBatchFileName c:\temp

(you may use quotation marks if needed)

will remove all empty subdirs under c:\temp folder

YourBatchFileName

will remove all empty subdirs under the current directory.

This is not possible. Linux permissions and windows permissions do not translate. They are machine specific. It would be a security hole to allow permissions to be set on files before they even arrive on the target system.

Assuming that the database is MS SQL Server 2012 or greater, here's a solution that works. The basic statement contains the in-line try-parse:

SELECT TRY_PARSE('02/04/2016 10:52:00' AS datetime USING 'en-US') AS Result;

Here's what we implemented in the production version:

UPDATE dbo.StagingInputReview
 SET ReviewedOn = 
     ISNULL(TRY_PARSE(RTrim(LTrim(ReviewedOnText)) AS datetime USING 'en-US'), getdate()),
 ModifiedOn = (getdate()), ModifiedBy = (suser_sname())
 -- Check for empty/null/'NULL' text
 WHERE not ReviewedOnText is null 
   AND RTrim(LTrim(ReviewedOnText))<>''
   AND Replace(RTrim(LTrim(ReviewedOnText)),'''','') <> 'NULL';

The ModifiedOn and ModifiedBy columns are just for internal database tracking purposes.

If you know what context managers are then you need nothing more to understand __enter__ and __exit__ magic methods. Lets see a very simple example.

In this example I am opening myfile.txt with help of open function. The try/finally block ensures that even if an unexpected exception occurs myfile.txt will be closed.

fp=open(r"C:\Users\SharpEl\Desktop\myfile.txt")
try:
    for line in fp:
        print(line)
finally:
    fp.close()

Now I am opening same file with with statement:

with open(r"C:\Users\SharpEl\Desktop\myfile.txt") as fp:
    for line in fp:
        print(line) 

If you look at the code, I didn't close the file & there is no try/finally block. Because with statement automatically closes myfile.txt . You can even check it by calling print(fp.closed) attribute -- which returns True.

This is because the file objects (fp in my example) returned by open function has two built-in methods __enter__ and __exit__. It is also known as context manager. __enter__ method is called at the start of with block and __exit__ method is called at the end. Note: with statement only works with objects that support the context mamangement protocol i.e. they have __enter__ and __exit__ methods. A class which implement both methods is known as context manager class.

Now lets define our own context manager class.

 class Log:
    def __init__(self,filename):
        self.filename=filename
        self.fp=None    
    def logging(self,text):
        self.fp.write(text+'\n')
    def __enter__(self):
        print("__enter__")
        self.fp=open(self.filename,"a+")
        return self    
    def __exit__(self, exc_type, exc_val, exc_tb):
        print("__exit__")
        self.fp.close()

with Log(r"C:\Users\SharpEl\Desktop\myfile.txt") as logfile:
    print("Main")
    logfile.logging("Test1")
    logfile.logging("Test2")

I hope now you have basic understanding of both __enter__ and __exit__ magic methods.

Try:

git submodule init
git submodule update

subprocess.Popen takes a list of arguments:

from subprocess import Popen, PIPE

process = Popen(['swfdump', '/tmp/filename.swf', '-d'], stdout=PIPE, stderr=PIPE)
stdout, stderr = process.communicate()

There's even a section of the documentation devoted to helping users migrate from os.popen to subprocess.

I have updated your jsfiddle and here is CSS changes you need to do:

#content
{

    margin-right: -210px;
    width:100%;
    float:left;
    background-color:AppWorkspace;
}

What happens with bittorrent and a DHT is that at the beginning bittorrent uses information embedded in the torrent file to go to either a tracker or one of a set of nodes from the DHT. Then once it finds one node, it can continue to find others and persist using the DHT without needing a centralized tracker to maintain it.

The original information bootstraps the later use of the DHT.

1. First find out the Procees id (pid) which has occupied the required port.(e.g 5434)

   ps aux | grep 5434

2.kill that process

   kill -9 <pid>

To avoid the "however" in Erandac's answer in combination of Daniel's and Salman's answers, one may use one of the following "partition workarounds"

SELECT customerID, myDate

  -- partition ranking works only with CTE / from MySQL 8.0 on
  , RANK() OVER (PARTITION BY customerID ORDER BY dateFrom) AS rank, 

  -- Erandac's method in combination of Daniel's and Salman's
  -- count all items in sequence, maximum reaches row count.
  , IF(customerID=@_lastRank, @_curRank:=@_curRank, @_curRank:=@_sequence+1) AS sequenceRank
  , @_sequence:=@_sequence+1 as sequenceOverAll

  -- Dense partition ranking, works also with MySQL 5.7
  -- remember to set offset values in from clause
  , IF(customerID=@_lastRank, @_nxtRank:=@_nxtRank, @_nxtRank:=@_nxtRank+1 ) AS partitionRank
  , IF(customerID=@_lastRank, @_overPart:=@_overPart+1, @_overPart:=1 ) AS partitionSequence

  , @_lastRank:=customerID
FROM myCustomers, 
  (SELECT @_curRank:=0, @_sequence:=0, @_lastRank:=0, @_nxtRank:=0, @_overPart:=0 ) r
ORDER BY customerID, myDate

The partition ranking in the 3rd variant in this code snippet will return continous ranking numbers. this will lead to a data structur similar to the rank() over partition by result. As an example, see below. In particular, the partitionSequence will always start with 1 for each new partitionRank, using this method:

customerID    myDate   sequenceRank (Erandac)
                          |    sequenceOverAll
                          |     |   partitionRank
                          |     |     | partitionSequence
                          |     |     |    | lastRank

var res = from s in Splitting 
          join c in Customer on s.CustomerId equals c.Id
         where c.Id == customrId
            && c.CompanyId == companyId
        select s;

Using Extension methods:

var res = Splitting.Join(Customer,
                 s => s.CustomerId,
                 c => c.Id,
                 (s, c) => new { s, c })
           .Where(sc => sc.c.Id == userId && sc.c.CompanyId == companId)
           .Select(sc => sc.s);

Instead of adding the line breaks with nl2br() and then removing the line breaks with explode(), try using the line break character '\r' or '\n' or '\r\n'.

<?php     $options= file_get_contents("employees.txt");     $options=explode("\n",$options);        // try \r as well.      foreach ($options as $singleOption){         echo "<option value='".$singleOption."'>".$singleOption."</option>";     }   ?> 

This could also fix the issue if the problem was due to Google Spreadsheets reading the line breaks.

The other answer below by Eric is wrong. The namespace declaration he mentioned had nothing to do with the problem.

The real reason it doesn't work is due to security concerns (cf. issue 4197, issue 111905).

Imagine this scenario:

1. You receive an email message from an attacker containing a web page as an attachment, which you download.

2. You open the now-local web page in your browser.

3. The local web page creates an <iframe> whose source is https://mail.google.com/mail/.

4. Because you are logged in to Gmail, the frame loads the messages in your inbox.

5. The local web page reads the contents of the frame by using JavaScript to access frames[0].document.documentElement.innerHTML. (An online web page would not be able to perform this step because it would come from a non-Gmail origin; the same-origin policy would cause the read to fail.)

6. The local web page places the contents of your inbox into a <textarea> and submits the data via a form POST to the attacker's web server. Now the attacker has your inbox, which may be useful for spamming or identify theft.

Chrome foils the above scenario by putting restrictions on local files opened using Chrome. To overcome these restrictions, we've got two solutions:

1. Try running Chrome with the --allow-file-access-from-files flag. I've not tested this myself, but if it works, your system will now also be vulnerable to scenarios of the kind mentioned above.

2. Upload it to a host, and problem solved.

One case when reinterpret_cast is necessary is when interfacing with opaque data types. This occurs frequently in vendor APIs over which the programmer has no control. Here's a contrived example where a vendor provides an API for storing and retrieving arbitrary global data:

// vendor.hpp
typedef struct _Opaque * VendorGlobalUserData;
void VendorSetUserData(VendorGlobalUserData p);
VendorGlobalUserData VendorGetUserData();

To use this API, the programmer must cast their data to VendorGlobalUserData and back again. static_cast won't work, one must use reinterpret_cast:

// main.cpp
#include "vendor.hpp"
#include <iostream>
using namespace std;

struct MyUserData {
    MyUserData() : m(42) {}
    int m;
};

int main() {
    MyUserData u;

        // store global data
    VendorGlobalUserData d1;
//  d1 = &u;                                          // compile error
//  d1 = static_cast<VendorGlobalUserData>(&u);       // compile error
    d1 = reinterpret_cast<VendorGlobalUserData>(&u);  // ok
    VendorSetUserData(d1);

        // do other stuff...

        // retrieve global data
    VendorGlobalUserData d2 = VendorGetUserData();
    MyUserData * p = 0;
//  p = d2;                                           // compile error
//  p = static_cast<MyUserData *>(d2);                // compile error
    p = reinterpret_cast<MyUserData *>(d2);           // ok

    if (p) { cout << p->m << endl; }
    return 0;
}

Below is a contrived implementation of the sample API:

// vendor.cpp
static VendorGlobalUserData g = 0;
void VendorSetUserData(VendorGlobalUserData p) { g = p; }
VendorGlobalUserData VendorGetUserData() { return g; }

I was installing appium by npm install -g appium and getting the same error on Windows 10.

Below command worked for me:

npm --add-python-to-path='true' --debug install --global windows-build-tools

I think the solution from medopal is what you are looking for.

But just another alternative solution is to use a HashMap and use the key (Integer) to store positions.

This way you won't need to populate it with nulls etc initially, just stick the position and the object in the map as you go along. You can write a couple of lines at the end to convert it to a List if you need it that way.

Java 9 & Unified JVM Logging

JEP 158 introduces a common logging system for all components of the JVM which will change (and IMO simplify) how logging works with GC. JEP 158 added a new command-line option to control logging from all components of the JVM:

-Xlog

For example, the following option:

-Xlog:gc

will log messages tagged with gc tag using info level to stdout. Or this one:

-Xlog:gc=debug:file=gc.txt:none

would log messages tagged with gc tag using debug level to a file called gc.txt with no decorations. For more detailed discussion, you can checkout the examples in the JEP page.

This is Windows related issue where SQL Server does not have the appropriate permission to the folder that contains .bak file and hence this error.

The easiest work around is to copy your .bak file to default SQL backup location which has all the necessary permissions. You do not need to fiddle with anything else. In SQL SERVER 2012, this location is

D:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Backup (SQL 2012)
C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup (SQL 2014)
C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\Backup (SQL 2016)

I made an animated GIF of the steps in the accepted answer. This is from MSSQL Server 2012

I was having this issue while sending files with regional characters in their names like: VeryRegiónal file - name.pdf.

The solution was to clear filename before attaching it to the email.

Go through project properties -> Reference Paths

Then add folder with DLL's
