Try this:

int selectedIndex = comboBox1.SelectedIndex;
comboBox1.SelectedItem.ToString();
int selectedValue = (int)comboBox1.Items[selectedIndex];

Well I will put similar solution that is working fine for me.

 private void DataGrid1_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            try
            {
                if (DataGrid1.SelectedItem != null)
                {
                    if (DataGrid1.SelectedItem is YouCustomClass)
                    {
                        var row = (YouCustomClass)DataGrid1.SelectedItem;

                        if (row != null)
                        {
                            // Do something...

                            //  ButtonSaveData.IsEnabled = true;

                            //  LabelName.Content = row.Name;

                        }
                    }
                }
            }
            catch (Exception)
            {
            }
        }

You don't need to iterate through the DataGrid rows, you can achieve your goal with a more simple solution. In order to match your row you can iterate through you collection that was bound to your DataGrid.ItemsSource property then assign this item to you DataGrid.SelectedItem property programmatically, alternatively you can add it to your DataGrid.SelectedItems collection if you want to allow the user to select more than one row. See the code below:

<Window x:Class="ProgGridSelection.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525" Loaded="OnWindowLoaded">
<StackPanel>
    <DataGrid Name="empDataGrid" ItemsSource="{Binding}" Height="200"/>
    <TextBox Name="empNameTextBox"/>
    <Button Content="Click" Click="OnSelectionButtonClick" />
</StackPanel>

public partial class MainWindow : Window
{
    public class Employee
    {
        public string Code { get; set; }
        public string Name { get; set; }
    }

    private ObservableCollection<Employee> _empCollection;

    public MainWindow()
    {
        InitializeComponent();
    }

    private void OnWindowLoaded(object sender, RoutedEventArgs e)
    {
        // Generate test data
        _empCollection =
            new ObservableCollection<Employee>
                {
                    new Employee {Code = "E001", Name = "Mohammed A. Fadil"},
                    new Employee {Code = "E013", Name = "Ahmed Yousif"},
                    new Employee {Code = "E431", Name = "Jasmin Kamal"},
                };

        /* Set the Window.DataContext, alternatively you can set your
         * DataGrid DataContext property to the employees collection.
         * on the other hand, you you have to bind your DataGrid
         * DataContext property to the DataContext (see the XAML code)
         */
        DataContext = _empCollection;
    }

    private void OnSelectionButtonClick(object sender, RoutedEventArgs e)
    {
        /* select the employee that his name matches the
         * name on the TextBox
         */
        var emp = (from i in _empCollection
                   where i.Name == empNameTextBox.Text.Trim()
                   select i).FirstOrDefault();

        /* Now, to set the selected item on the DataGrid you just need
         * assign the matched employee to your DataGrid SeletedItem
         * property, alternatively you can add it to your DataGrid
         * SelectedItems collection if you want to allow the user
         * to select more than one row, e.g.:
         *    empDataGrid.SelectedItems.Add(emp);
         */
        if (emp != null)
            empDataGrid.SelectedItem = emp;
    }
}

final ListView lv = (ListView) findViewById(R.id.ListView01);

lv.setOnItemClickListener(new OnItemClickListener() {
      public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) {
        String selectedFromList =(String) (lv.getItemAtPosition(myItemInt));

      }                 
});

I hope this fixes your problem.

Their names can be a bit confusing :). Here's a summary:

• The SelectedItem property returns the entire object that your list is bound to. So say you've bound a list to a collection of Category objects (with each Category object having Name and ID properties). eg. ObservableCollection<Category>. The SelectedItem property will return you the currently selected Category object. For binding purposes however, this is not always what you want, as this only enables you to bind an entire Category object to the property that the list is bound to, not the value of a single property on that Category object (such as its ID property).

• Therefore we have the SelectedValuePath property and the SelectedValue property as an alternative means of binding (you use them in conjunction with one another). Let's say you have a Product object, that your view is bound to (with properties for things like ProductName, Weight, etc). Let's also say you have a CategoryID property on that Product object, and you want the user to be able to select a category for the product from a list of categories. You need the ID property of the Category object to be assigned to the CategoryID property on the Product object. This is where the SelectedValuePath and the SelectedValue properties come in. You specify that the ID property on the Category object should be assigned to the property on the Product object that the list is bound to using SelectedValuePath='ID', and then bind the SelectedValue property to the property on the DataContext (ie. the Product).

The example below demonstrates this. We have a ComboBox bound to a list of Categories (via ItemsSource). We're binding the CategoryID property on the Product as the selected value (using the SelectedValue property). We're relating this to the Category's ID property via the SelectedValuePath property. And we're saying only display the Name property in the ComboBox, with the DisplayMemberPath property).

<ComboBox ItemsSource="{Binding Categories}" 
          SelectedValue="{Binding CategoryID, Mode=TwoWay}" 
          SelectedValuePath="ID" 
          DisplayMemberPath="Name" />

public class Category
{
    public int ID { get; set; }
    public string Name { get; set; }
}

public class Product
{
    public int CategoryID { get; set; }
}

It's a little confusing initially, but hopefully this makes it a bit clearer... :)

Chris

Yocoder is right,

Inside the DataTemplate, your DataContext is set to the Rule its currently handling..

To access the parents DataContext, you can also consider using a RelativeSource in your binding:

<TextBlock Text="{Binding RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type ____Your Parent control here___ }}, Path=DataContext.SelectedRule.Name}" />

More info on RelativeSource can be found here:

http://msdn.microsoft.com/en-us/library/system.windows.data.relativesource.aspx

I realise this has already had an answer accepted, but I put this together to solve the problem. It uses a similar idea to Delta's solution, but without the need to subclass the TreeView:

public class BindableSelectedItemBehavior : Behavior<TreeView>
{
    #region SelectedItem Property

    public object SelectedItem
    {
        get { return (object)GetValue(SelectedItemProperty); }
        set { SetValue(SelectedItemProperty, value); }
    }

    public static readonly DependencyProperty SelectedItemProperty =
        DependencyProperty.Register("SelectedItem", typeof(object), typeof(BindableSelectedItemBehavior), new UIPropertyMetadata(null, OnSelectedItemChanged));

    private static void OnSelectedItemChanged(DependencyObject sender, DependencyPropertyChangedEventArgs e)
    {
        var item = e.NewValue as TreeViewItem;
        if (item != null)
        {
            item.SetValue(TreeViewItem.IsSelectedProperty, true);
        }
    }

    #endregion

    protected override void OnAttached()
    {
        base.OnAttached();

        this.AssociatedObject.SelectedItemChanged += OnTreeViewSelectedItemChanged;
    }

    protected override void OnDetaching()
    {
        base.OnDetaching();

        if (this.AssociatedObject != null)
        {
            this.AssociatedObject.SelectedItemChanged -= OnTreeViewSelectedItemChanged;
        }
    }

    private void OnTreeViewSelectedItemChanged(object sender, RoutedPropertyChangedEventArgs<object> e)
    {
        this.SelectedItem = e.NewValue;
    }
}

You can then use this in your XAML as:

<TreeView>
    <e:Interaction.Behaviors>
        <behaviours:BindableSelectedItemBehavior SelectedItem="{Binding SelectedItem, Mode=TwoWay}" />
    </e:Interaction.Behaviors>
</TreeView>

Hopefully it will help someone!

Combine Dynamic SQL with OpenQuery. (This goes to a Teradata server)

DECLARE 
    @dayOfWk    TINYINT = DATEPART(DW, GETDATE()),
    @qSQL       NVARCHAR(MAX) = '';

SET @qSQL = '
SELECT
    *
FROM
    OPENQUERY(TERASERVER,''
        SELECT DISTINCT
            CASE
                WHEN ' + CAST(@dayOfWk AS NCHAR(1)) + ' = 2
                THEN ''''Monday''''
                ELSE ''''Not Monday''''
            END
        '');';

EXEC sp_executesql @qSQL;

Running nginx -t through your commandline will issue out a test and append the output with the filepath to the configuration file (with either an error or success message).

To add another esoteric way, this works aswell:

var obj = {a: 1, b:2, c:3}
var newobj = {a,c}=obj && {a,c}
// {a: 1, c:3}

but you have to write the prop names twice.

Jerryf's answer is fine, except for one flaw.

The onload event should be set before the src. Sometimes the src can be loaded instantly and never fire the onload event.

(Like Totty.js pointed out.)

var canvas = document.getElementById("c");
var ctx = canvas.getContext("2d");

var image = new Image();
image.onload = function() {
    ctx.drawImage(image, 0, 0);
};
image.src = "data:image/  png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAIAAAACDbGyAAAAAXNSR0IArs4c6QAAAAlwSFlzAAALEwAACxMBAJqcGAAAAAd0SU1FB9oMCRUiMrIBQVkAAAAZdEVYdENvbW1lbnQAQ3JlYXRlZCB3aXRoIEdJTVBXgQ4XAAAADElEQVQI12NgoC4AAABQAAEiE+h1AAAAAElFTkSuQmCC";

Long answer: it is possible!

1. Temporarily rename existing xampp folder
2. Install xampp 1.7.7 into xampp folder name
3. Folder containing just installed 1.7.7 distribution rename to different name and previously existing xampp folder rename back just to xampp.
4. In xampp folder rename php and apache folders to different names (I propose php_prev and apache_prev) so you can after switch back to them by renaming them back.
5. Copy apache and php folders from folder with xampp 1.7.7 into xampp directory

6. In xampp directory comment line apache/conf/httpd.conf:458

   #Include "conf/extra/httpd-perl.conf"

7. In xampp directory do next replaces in files:

php/pci.bat:15

from

"C:\xampp\php\.\php.exe" -f "\xampp\php\pci" -- %*

to

set XAMPPPHPDIR=C:\xampp\php "%XAMPPPHPDIR%\php.exe" -f "%XAMPPPHPDIR%\pci" -- %*

Enjoy new XAMPP with PHP 5.3

Aside from the fact that you are modifying the String prototype, there is nothing wrong with the function you provided. The way you would use it is this way:

"Hello {0},".format(["Bob"]);

If you wanted it as a stand-alone function, you could alter it slightly to this:

function format(string, object) {
    return string.replace(/{([^{}]*)}/g,
       function(match, group_match)
       {
           var data = object[group_match];
           return typeof data === 'string' ? data : match;
       }
    );
}

Vittore's method is also good; his function is called with each additional formating option being passed in as an argument, while yours expects an object.

What this actually looks like is John Resig's micro-templating engine.

In addition, you can build the binary package using the --binary option.

R CMD build --binary RJSONIO_0.2-3.tar.gz

Buffers can be used for taking a string or piece of data and doing base64 encoding of the result. For example:

> console.log(Buffer.from("Hello World").toString('base64'));
SGVsbG8gV29ybGQ=
> console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii'))
Hello World

Buffers are a global object, so no require is needed. Buffers created with strings can take an optional encoding parameter to specify what encoding the string is in. The available toString and Buffer constructor encodings are as follows:

'ascii' - for 7 bit ASCII data only. This encoding method is very fast, and will strip the high bit if set.

'utf8' - Multi byte encoded Unicode characters. Many web pages and other document formats use UTF-8.

'ucs2' - 2-bytes, little endian encoded Unicode characters. It can encode only BMP(Basic Multilingual Plane, U+0000 - U+FFFF).

'base64' - Base64 string encoding.

'binary' - A way of encoding raw binary data into strings by using only the first 8 bits of each character. This encoding method is deprecated and should be avoided in favor of Buffer objects where possible. This encoding will be removed in future versions of Node.

The line function implementation should be:

void addStudent(struct student person) {

}

person is not a type but a variable, you cannot use it as the type of a function parameter.

Also, make sure your struct is defined before the prototype of the function addStudent as the prototype uses it.

you can use the function

bind_rows(a,b)

from the dplyr library

If you just want to use AWT, then use Graphics.getFontMetrics (optionally specifying the font, for a non-default one) to get a FontMetrics and then FontMetrics.stringWidth to find the width for the specified string.

For example, if you have a Graphics variable called g, you'd use:

int width = g.getFontMetrics().stringWidth(text);

For other toolkits, you'll need to give us more information - it's always going to be toolkit-dependent.

This is a problem with your remote. When you do git push origin master, origin is the remote and master is the branch you're pushing.

When you do this:

git remote

I bet the list does not include origin. To re-add the origin remote:

git remote add origin [email protected]:your_github_username/your_github_app.git

Or, if it exists but is formatted incorrectly:

git remote rm origin
git remote add origin [email protected]:your_github_username/your_github_app.git

Just to summarize, here's a complete answer, that worked for me.

My problem was that when I used

[NSString stringWithUTF8String:(char *)data.bytes];

The string I got was unpredictable: Around 70% it did contain the expected value, but too often it resulted with Null or even worse: garbaged at the end of the string.

After some digging I switched to

[[NSString alloc] initWithBytes:(char *)data.bytes length:data.length encoding:NSUTF8StringEncoding];

And got the expected result every time.

It took me a while to locate why the sample application works but mine don't.

The library (Foundation.Framework) that the author refer to is the system library (from OS) where the iphone sdk (I am using 3.0) is not support any more.

Therefore the sample application (from about.com, http://www.appsamuck.com/day1.html) works but ours don't.

in php with function chr(13) :

echo '<textarea class="form-control" rows="5" style="width:100%;" name="responsable" placeholder="NOM prénom du responsable légal'.chr(13).'Adresse'.chr(13).'CP VILLE'.chr(13).'Téléphone'.chr(13).'Adresse de messagerie" id="responsable"></textarea>';

The ASCII character code 13 chr(13) is called a Carriage Return or CR

Its just a 2 line of code.

If you are passing data to a DOM element from the server, you should set the data on the element:

<a id="foo" data-foo="bar" href="#">foo!</a>

The data can then be accessed using .data() in jQuery:

console.log( $('#foo').data('foo') );
//outputs "bar"

However when you store data on a DOM node in jQuery using data, the variables are stored on the node object. This is to accommodate complex objects and references as storing the data on the node element as an attribute will only accommodate string values.

$('#foo').data('foo', 'baz');

console.log( $('#foo').attr('data-foo') );
//outputs "bar" as the attribute was never changed

console.log( $('#foo').data('foo') );
//outputs "baz" as the value has been updated on the object

Also, the naming convention for data attributes has a bit of a hidden "gotcha":

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('fooBarBaz') );
//outputs "fizz-buzz" as hyphens are automatically camelCase'd

The hyphenated key will still work:

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('foo-bar-baz') );
//still outputs "fizz-buzz"

However the object returned by .data() will not have the hyphenated key set:

$('#bar').data().fooBarBaz; //works
$('#bar').data()['fooBarBaz']; //works
$('#bar').data()['foo-bar-baz']; //does not work

It's for this reason I suggest avoiding the hyphenated key in javascript.

For HTML, keep using the hyphenated form. HTML attributes are supposed to get ASCII-lowercased automatically, so <div data-foobar></div>, <DIV DATA-FOOBAR></DIV>, and <dIv DaTa-FoObAr></DiV> are supposed to be treated as identical, but for the best compatibility the lower case form should be preferred.

The .data() method will also perform some basic auto-casting if the value matches a recognized pattern:

<a id="foo"
    href="#"
    data-str="bar"
    data-bool="true"
    data-num="15"
    data-json='{"fizz":["buzz"]}'>foo!</a>

$('#foo').data('str');  //`"bar"`
$('#foo').data('bool'); //`true`
$('#foo').data('num');  //`15`
$('#foo').data('json'); //`{fizz:['buzz']}`

This auto-casting ability is very convenient for instantiating widgets & plugins:

$('.widget').each(function () {
    $(this).widget($(this).data());
    //-or-
    $(this).widget($(this).data('widget'));
});

If you absolutely must have the original value as a string, then you'll need to use .attr():

<a id="foo" href="#" data-color="ABC123"></a>
<a id="bar" href="#" data-color="654321"></a>

$('#foo').data('color').length; //6
$('#bar').data('color').length; //undefined, length isn't a property of numbers

$('#foo').attr('data-color').length; //6
$('#bar').attr('data-color').length; //6

_{This was a contrived example. For storing color values, I used to use numeric hex notation (i.e. 0xABC123), but it's worth noting that hex was parsed incorrectly in jQuery versions before 1.7.2, and is no longer parsed into a Number as of jQuery 1.8 rc 1.}

jQuery 1.8 rc 1 changed the behavior of auto-casting. Before, any format that was a valid representation of a Number would be cast to Number. Now, values that are numeric are only auto-cast if their representation stays the same. This is best illustrated with an example.

<a id="foo"
    href="#"
    data-int="1000"
    data-decimal="1000.00"
    data-scientific="1e3"
    data-hex="0x03e8">foo!</a>

                              // pre 1.8    post 1.8
$('#foo').data('int');        //    1000        1000
$('#foo').data('decimal');    //    1000   "1000.00"
$('#foo').data('scientific'); //    1000       "1e3"
$('#foo').data('hex');        //    1000     "0x03e8"

If you plan on using alternative numeric syntaxes to access numeric values, be sure to cast the value to a Number first, such as with a unary + operator.

+$('#foo').data('hex'); // 1000

I know I am posting this answer little late, but I felt it is worth using Google's fuse location provider service to get the current location.

Main features of this api are :

1.Simple APIs: Lets you choose your accuracy level as well as power consumption.

2.Immediately available: Gives your apps immediate access to the best, most recent location.

3.Power-efficiency: It chooses the most efficient way to get the location with less power consumptions

4.Versatility: Meets a wide range of needs, from foreground uses that need highly accurate location to background uses that need periodic location updates with negligible power impact.

It is flexible in while updating in location also. If you want current location only when your app starts then you can use getLastLocation(GoogleApiClient) method.

If you want to update your location continuously then you can use requestLocationUpdates(GoogleApiClient,LocationRequest, LocationListener)

You can find a very nice blog about fuse location here and google doc for fuse location also can be found here.

Update

According to developer docs starting from Android O they have added new limits on background location.

If your app is running in the background, the location system service computes a new location for your app only a few times each hour. This is the case even when your app is requesting more frequent location updates. However if your app is running in the foreground, there is no change in location sampling rates compared to Android 7.1.1 (API level 25).

when you create an object using predefine class, at first you want to create a variable for storing that object. Then you can create object and store variable that you created.

class Student:
     def __init__(self):

# creating an object....

   student1=Student()

Actually this init method is the constructor of class.you can initialize that method using some attributes.. In that point , when you creating an object , you will have to pass some values for particular attributes..

class Student:
      def __init__(self,name,age):
            self.name=value
            self.age=value

 # creating an object.......

     student2=Student("smith",25)

This is yet another reason to use Joda Time

new DateMidnight(2010, 3, 5)

DateMidnight is now deprecated but the same effect can be achieved with Joda Time DateTime

DateTime dt = new DateTime(2010, 3, 5, 0, 0);

While it looks like your setup is correct, there are a few things to check:

1. The output of env - specifically PATH.
2. command -v java tells you what?
3. Is there a java executable in $JAVA_HOME\bin and does it have the execute bit set? If not chmod a+x java it.

I trust you have source'd your .profile after adding/changing the JAVA_HOME and PATH?

Also, you can help yourself in future maintenance of your JDK installation by writing this instead:

export JAVA_HOME=/home/aqeel/development/jdk/jdk1.6.0_35
export PATH=$JAVA_HOME/bin:$PATH

Then you only need to update one env variable when you setup the JDK installation.

Finally, you may need to run hash -r to clear the Bash program cache. Other shells may need a similar command.

Cheers,

I ran task manager and looked for httpd.exe in process. Their were two of them running. I stopped one of them gone back to xampp control pannel and started apache. It worked.

I've an object (basically a VO) in Java and I don't know its type. I need to get values which are not null in that object.

Maybe you don't necessary need reflection for that -- here is a plain OO design that might solve your problem:

1. Add an interface Validation which expose a method validate which checks the fields and return whatever is appropriate.
2. Implement the interface and the method for all VO.
3. When you get a VO, even if it's concrete type is unknown, you can typecast it to Validation and check that easily.

I guess that you need the field that are null to display an error message in a generic way, so that should be enough. Let me know if this doesn't work for you for some reason.

I figured it out, and it's actually pretty straight forward.

Set your variable:

$image1 = "img/products/image1.jpg";

Then ceate a cell, position it, then rather than setting where the image is, use the variable you created above with the following:

$this->Cell( 40, 40, $pdf->Image($image1, $pdf->GetX(), $pdf->GetY(), 33.78), 0, 0, 'L', false );

Now the cell will move up and down with content if other cells around it move.

Hope this helps others in the same boat.

It is possible. Have a look at JSch.addIdentity(...)

This allows you to use key either as byte array or to read it from file.

            String host = "192.18.0.246";

            System.out.println("identity added ");

You can also compare with double value

BigDecimal a= new BigDecimal("1.1"); BigDecimal b =new BigDecimal("1.1");
System.out.println(a.doubleValue()==b.doubleValue());

If you don't care too much about performance and want to use the straightforward way, you can use either DIV or IDIV.

DIV or IDIV takes only one operand where it divides a certain register with this operand, the operand can be register or memory location only.

When operand is a byte: AL = AL / operand, AH = remainder (modulus).

Ex:

MOV AL,31h ; Al = 31h

DIV BL ; Al (quotient)= 08h, Ah(remainder)= 01h

when operand is a word: AX = (AX) / operand, DX = remainder (modulus).

Ex:

MOV AX,9031h ; Ax = 9031h

DIV BX ; Ax=1808h & Dx(remainder)= 01h

It could be some un-initialized function pointer, in particular if you have corrupted memory (then the bogus vtable of C++ bad pointers to invalid objects might give that).

BTW gdb watchpoints & tracepoints, and also valgrind might be useful (if available) to debug such issues. Or some address sanitizer.

Here, give this a shot (this is just a pseudocode)

using System;
using System.Data;
using System.Data.SqlClient;


public class PullDataTest
{
    // your data table
    private DataTable dataTable = new DataTable();

    public PullDataTest()
    {
    }

    // your method to pull data from database to datatable   
    public void PullData()
    {
        string connString = @"your connection string here";
        string query = "select * from table";

        SqlConnection conn = new SqlConnection(connString);        
        SqlCommand cmd = new SqlCommand(query, conn);
        conn.Open();

        // create data adapter
        SqlDataAdapter da = new SqlDataAdapter(cmd);
        // this will query your database and return the result to your datatable
        da.Fill(dataTable);
        conn.Close();
        da.Dispose();
    }
}

In Python 2, raw_input() returns a string, and input() tries to run the input as a Python expression.

Since getting a string was almost always what you wanted, Python 3 does that with input(). As Sven says, if you ever want the old behaviour, eval(input()) works.

You could get the full path as a string then split it into a list using your operating system's separator character. Then you get the program name, folder name etc by accessing the elements from the end of the list using negative indices.

Like this:

import os
strPath = os.path.realpath(__file__)
print( f"Full Path    :{strPath}" )
nmFolders = strPath.split( os.path.sep )
print( "List of Folders:", nmFolders )
print( f"Program Name :{nmFolders[-1]}" )
print( f"Folder Name  :{nmFolders[-2]}" )
print( f"Folder Parent:{nmFolders[-3]}" )

The output of the above was this:

Full Path    :C:\Users\terry\Documents\apps\environments\dev\app_02\app_02.py
List of Folders: ['C:', 'Users', 'terry', 'Documents', 'apps', 'environments', 'dev', 'app_02', 'app_02.py']
Program Name :app_02.py
Folder Name  :app_02
Folder Parent:dev

Full combo of build/ clean project + build/ rebuild project + file/ Invalidate caches / restart works for me!

RUN /bin/sh -c "apk add --no-cache bash"

worked for me.

Adding margin to align images:

Since we wanted the image to be left-aligned, we added:

img {
  margin-right: auto;
}

Similarly for image to be right-aligned, we can add margin-right: auto;. The snippet shows a demo for both types of alignment.

Good Luck...

There actually doesn't seem to be a lot of explanation on this subject apparently but the exit codes are supposed to be used to give an indication on how the thread exited, 0 tends to mean that it exited safely whilst anything else tends to mean it didn't exit as expected. But then this exit code can be set in code by yourself to completely overlook this.

The closest link I could find to be useful for more information is this

Quote from above link:

What ever the method of exiting, the integer that you return from your process or thread must be values from 0-255(8bits). A zero value indicates success, while a non zero value indicates failure. Although, you can attempt to return any integer value as an exit code, only the lowest byte of the integer is returned from your process or thread as part of an exit code. The higher order bytes are used by the operating system to convey special information about the process. The exit code is very useful in batch/shell programs which conditionally execute other programs depending on the success or failure of one.

From the Documentation for GetEXitCodeThread

Important The GetExitCodeThread function returns a valid error code defined by the application only after the thread terminates. Therefore, an application should not use STILL_ACTIVE (259) as an error code. If a thread returns STILL_ACTIVE (259) as an error code, applications that test for this value could interpret it to mean that the thread is still running and continue to test for the completion of the thread after the thread has terminated, which could put the application into an infinite loop.

My understanding of all this is that the exit code doesn't matter all that much if you are using threads within your own application for your own application. The exception to this is possibly if you are running a couple of threads at the same time that have a dependency on each other. If there is a requirement for an outside source to read this error code, then you can set it to let other applications know the status of your thread.

in your example you could use strip but you have to provide the space

string = '"" " " ""\\1" " "" ""'
string.strip('" ')  # output '\\1'

note the \' in the output is the standard python quotes for string output

the value of your variable is '\\1'

I came up with a slightly different solution. It's a bit hack-ish, but here is the mapping:

<servlet-mapping>   
    <servlet-name>default</servlet-name>
    <url-pattern>*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.jpg</url-pattern>
</servlet-mapping>
<servlet-mapping>
 <servlet-name>default</servlet-name>
    <url-pattern>*.png</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping>

<servlet-mapping>
    <servlet-name>myAppServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

This basically just maps all content files by extension to the default servlet, and everything else to "myAppServlet".

It works in both Jetty and Tomcat.

The issue of erroneous leftover entries in the .csproj file still occurs with VS2015update3 and can also occur if you try to change the signing certificate for a different one (even if that is one generated using the 'new' option in the certificate selection dropdown). The advice in the accepted answer (mark as not signed, save, unload project, edit .csproj, remove the properties relating to the old certificates/thumbprints/keys & reload project, set certificate) is reliable.

Make a text using notepad or any text editor of you choice. Open notepad, write this short command "cmd.exe" without the quote aand save it as cmd.bat.

Click cmd.bat and choose "run as administrator".

How about disabled=disabled:

<input id="price_from" value="price from " disabled="disabled">????????????

Problem is if you don't want user to edit them, why display them in input? You can hide them even if you want to submit a form. And to display information, just use other tag instead.

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

@Zags solution was gorgeous!

I would add, though, a condition for datefields in order to make it JSON friendly.

Bonus Round

If you want a django model that has a better python command-line display, have your models child class the following:

from django.db import models
from django.db.models.fields.related import ManyToManyField

class PrintableModel(models.Model):
    def __repr__(self):
        return str(self.to_dict())

    def to_dict(self):
        opts = self._meta
        data = {}
        for f in opts.concrete_fields + opts.many_to_many:
            if isinstance(f, ManyToManyField):
                if self.pk is None:
                    data[f.name] = []
                else:
                    data[f.name] = list(f.value_from_object(self).values_list('pk', flat=True))
            elif isinstance(f, DateTimeField):
                if f.value_from_object(self) is not None:
                    data[f.name] = f.value_from_object(self).timestamp()
            else:
                data[f.name] = None
            else:
                data[f.name] = f.value_from_object(self)
        return data

    class Meta:
        abstract = True

So, for example, if we define our models as such:

class OtherModel(PrintableModel): pass

class SomeModel(PrintableModel):
    value = models.IntegerField()
    value2 = models.IntegerField(editable=False)
    created = models.DateTimeField(auto_now_add=True)
    reference1 = models.ForeignKey(OtherModel, related_name="ref1")
    reference2 = models.ManyToManyField(OtherModel, related_name="ref2")

Calling SomeModel.objects.first() now gives output like this:

{'created': 1426552454.926738,
'value': 1, 'value2': 2, 'reference1': 1, u'id': 1, 'reference2': [1]}

NERDcommenter is an excellent plugin for commenting which automatically detects a number of filetypes and their associated comment characters. Ridiculously easy to install using Pathogen.

Comment with <leader>cc. Uncomment with <leader>cu. And toggle comments with <leader>c<space>.

(The default <leader> key in vim is \)

<p>tetxetextex</p>
<ol><li>first element</li></ol>
<p>other textetxeettx</p>

Because both <p> and <ol> are element rendered as block.

Disclaimer: I am the author of Jsonix, a powerful open-source XML<->JSON JavaScript mapping library.

Today I've released the new version of the Jsonix Schema Compiler, with the new JSON Schema generation feature.

Let's take the Purchase Order schema for example. Here's a fragment:

  <xsd:element name="purchaseOrder" type="PurchaseOrderType"/>

  <xsd:complexType name="PurchaseOrderType">
    <xsd:sequence>
      <xsd:element name="shipTo" type="USAddress"/>
      <xsd:element name="billTo" type="USAddress"/>
      <xsd:element ref="comment" minOccurs="0"/>
      <xsd:element name="items"  type="Items"/>
    </xsd:sequence>
    <xsd:attribute name="orderDate" type="xsd:date"/>
  </xsd:complexType>

You can compile this schema using the provided command-line tool:

java -jar jsonix-schema-compiler-full.jar
    -generateJsonSchema
    -p PO
    schemas/purchaseorder.xsd

The compiler generates Jsonix mappings as well the matching JSON Schema.

Here's what the result looks like (edited for brevity):

{
    "id":"PurchaseOrder.jsonschema#",
    "definitions":{
        "PurchaseOrderType":{
            "type":"object",
            "title":"PurchaseOrderType",
            "properties":{
                "shipTo":{
                    "title":"shipTo",
                    "allOf":[
                        {
                            "$ref":"#/definitions/USAddress"
                        }
                    ]
                },
                "billTo":{
                    "title":"billTo",
                    "allOf":[
                        {
                            "$ref":"#/definitions/USAddress"
                        }
                    ]
                }, ...
            }
        },
        "USAddress":{ ... }, ...
    },
    "anyOf":[
        {
            "type":"object",
            "properties":{
                "name":{
                    "$ref":"http://www.jsonix.org/jsonschemas/w3c/2001/XMLSchema.jsonschema#/definitions/QName"
                },
                "value":{
                    "$ref":"#/definitions/PurchaseOrderType"
                }
            },
            "elementName":{
                "localPart":"purchaseOrder",
                "namespaceURI":""
            }
        }
    ]
}

Now this JSON Schema is derived from the original XML Schema. It is not exactly 1:1 transformation, but very very close.

The generated JSON Schema matches the generatd Jsonix mappings. So if you use Jsonix for XML<->JSON conversion, you should be able to validate JSON with the generated JSON Schema. It also contains all the required metadata from the originating XML Schema (like element, attribute and type names).

Disclaimer: At the moment this is a new and experimental feature. There are certain known limitations and missing functionality. But I'm expecting this to manifest and mature very fast.

HTML forms support GET and POST. (HTML5 at one point added PUT/DELETE, but those were dropped.)

XMLHttpRequest supports every method, including CHICKEN, though some method names are matched against case-insensitively (methods are case-sensitive per HTTP) and some method names are not supported at all for security reasons (e.g. CONNECT).

Browsers are slowly converging on the rules specified by XMLHttpRequest, but as the other comment pointed out there are still some differences.

If you want the accepted answer to work in JQuery 3 change the code like this:

var scrollItems = menuItems.map(function () {
    var id = $(this).attr("href");
    try {
        var item = $(id);
      if (item.length) {
        return item;
      }
    } catch {}
  });

I also added a try-catch to prevent javascript from crashing if there is no element by that id. Feel free to improve it even more ;)

I have used an html template. In this template's custom.js file, there was a function like this:

    jQuery(document).ready(function($) {

       $(window).on('load', function() {
          //...
       });

    });

But this function was not working when I go to back after go to other page.

So, I tried this and it has worked:

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

   //Window Load Start
   window.addEventListener('load', function() {
       jQuery(document).ready(function($) {
          //...
       });
   });

Now, I have 2 "ready" function but it doesn't give any error and the page is working very well.

Nevertheless, I have to declare that it has tested on Windows 10 - Opera v53 and Edge v42 but no other browsers. Keep in mind this...

Note: jquery version was 3.3.1 and migrate version was 3.0.0

In any case, you can override height with max-height.

One hackish way to define an exit method in context:

class Bar; def exit; end; end 

This works because exit in the initializer will be resolved as self.exit¹. In addition, this approach allows using the object after it has been created, as in: b = B.new.

But really, one shouldn't be doing this: don't have exit (or even puts) there to begin with.

(And why is there an "infinite" loop and/or user input in an intiailizer? This entire problem is primarily the result of poorly structured code.)

¹ Remember Kernel#exit is only a method. Since Kernel is included in every Object, then it's merely the case that exit normally resolves to Object#exit. However, this can be changed by introducing an overridden method as shown - nothing fancy.

Node.js is a server side JS platform build on V8 which is chrome java-script runtime.

It leverages the use of java-script on servers too.

You can use JS Date() function or Date class.

As already mentioned by several people, eq is the right operator here.

If you use warnings; in your script, you'll get warnings about this (and many other useful things); I'd recommend use strict; as well.

You can do it with:

dotnet ef migrations remove

Warning

Take care not to remove any migrations which are already applied to production databases. Not doing so will prevent you from being able to revert it, and may break the assumptions made by subsequent migrations.

I would recommend using Glazed Lists for this. It makes it very easy to map a data structure to a table model.

To react to the mouseclick on the JTable, use an ActionListener: ActionListener on JLabel or JTable cell

From the Graph API documentation.

• /OBJECT_ID/picture returns a redirect to the object's picture (in this case the users)
• /OBJECT_ID/?fields=picture returns the picture's URL

Examples:

<img src="https://graph.facebook.com/4/picture"/> uses a HTTP 301 redirect to Zuck's profile picture

https://graph.facebook.com/4?fields=picture returns the URL itself

I'm sure the original poster's issue has long since been resolved. However, I had this same issue, so I thought I'd explain what was causing this problem for me.

I was doing a union query with two tables -- 'foo' and 'foo_bar'. However, in my SQL statement, I had a typo: 'foo.bar'

So, instead of telling me that the 'foo.bar' table doesn't exist, the error message indicates that the command was denied -- as though I don't have permissions.

Hope this helps someone.

ES6 of the day here;

const json_getAllKeys = data => (
  data.reduce((keys, obj) => (
    keys.concat(Object.keys(obj).filter(key => (
      keys.indexOf(key) === -1))
    )
  ), [])
)

And yes it can be written in very long one line;

const json_getAllKeys = data => data.reduce((keys, obj) => keys.concat(Object.keys(obj).filter(key => keys.indexOf(key) === -1)), [])

EDIT: Returns all first order keys if the input is of type array of objects

Mine was a name spacing issue. I had two files with the same name. Just renamed them and it resolved.

Always gotta check the 'stupid me' box first before looking elsewhere. : )

Yes, there are a number of ways that you can do this. The "fastest" way would be to add CSS to the div similar to the following

#term-defs {
height: 300px;
overflow: scroll; }

This will force the div to be scrollable, but this might not get the best effect. Another route would be to absolute fix the position of the items at the top, you can play with this by doing something like this.

#top {
  position: fixed;
  top: 0;
  left: 0;
  z-index: 999;
  width: 100%;
  height: 23px;
}

This will fix it to the top, on top of other content with a height of 23px.

The final implementation will depend on what effect you really want.

The solution below works in Firefox also, without any JavaScript:

option[default] {_x000D_
  display: none;_x000D_
}

<select>_x000D_
  <option value="" default selected>Select Your Age</option>_x000D_
  <option value="1">1</option>_x000D_
  <option value="2">2</option>_x000D_
  <option value="3">3</option>_x000D_
  <option value="4">4</option>_x000D_
</select>

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

As mentioned in the error, the official manual and the comments:

Replace

public function TSStatus($host, $queryPort)

with

public function __construct($host, $queryPort)

Incremental development means that different parts of a software project are continuously integrated into the whole, instead of a monolithic approach where all the different parts are assembled in one or a few milestones of the project.

Iterative means that once a first version of a component is complete it is tested, reviewed and the results are almost immediately transformed into a new version (iteration) of this component.

So as a first result: iterative development doesn't need to be incremental and vice versa, but these methods are a good fit.

Agile development aims to reduce massive planing overhead in software projects to allow fast reactions to change e.g. in customer wishes. Incremental and iterative development are almost always part of an agile development strategy. There are several approaches to Agile development (e.g. scrum).

CONCAT with a null value returns null, so the easiest solution is:

UPDATE myTable SET spares = IFNULL (CONCAT( spares , "string" ), "string")

I used

View.inflate(getContext(), R.layout.whatever, null)

The using of View.inflate prevents the warning of using null at getLayoutInflater().inflate().

Swift 3:

if let data = text.data(using: String.Encoding.utf8) {
    do {
        let json = try JSONSerialization.jsonObject(with: data, options: .mutableContainers) as? [String:Any]
        print(json)
    } catch {
        print("Something went wrong")
    }
}

Just install apt-get install php5-mysqlnd Restart Apache service apache2 restart

I had this exact issue, and created a GitHub project for testing and figuring out the correct settings.

It contains a working Dockerfile with supporting scripts, and a simple docker-compose.yml for quick testing.

Call HttpURLConnection.setRequestMethod("POST") and HttpURLConnection.setDoOutput(true); Actually only the latter is needed as POST then becomes the default method.

I've been using keyup on a number field, but today I noticed in chrome the input has up/down buttons to increase/decrease the value which aren't recognized by keyup.

My solution is to use keyup and change together:

(keyup)="unitsChanged[i] = true" (change)="unitsChanged[i] = true"

Initial tests indicate this works fine, will post back if any bugs found after further testing.

As you see, that's actually a natural error ..

A typical construct for reading from an Unpickler object would be like this ..

try:
    data = unpickler.load()
except EOFError:
    data = list()  # or whatever you want

EOFError is simply raised, because it was reading an empty file, it just meant End of File ..

In some cases (blocks without any content, but with background) it can be overridden using borders, individually for every block.

For example:

.colored {
  background: #000;
  border: 1px solid #ccc;
  width: 8px;
  height: 8px;
}

@media print {
  .colored div {
    border: 4px solid #000;
    width: 0;
    height: 0;
  }
}

You can also use Java's implicit conversion:

BigInteger m = new BigInteger(bytemsg); 
String mStr = "" + m;  // mStr now contains string representation of m.

In case you

• installed ruby gems with sudo
• want to install gems without sudo
• don't want to install rvm/rbenv

add the following to your .bash_profile :

export GEM_HOME=/Users/‹your_user›/.gem
export PATH="$GEM_HOME/bin:$PATH"

Open a new tab in Terminal OR source ~/.bash_profile and you're good to go!

The guide you linked now has a Tear Down section:

Talking to the master with the appropriate credentials, run:

kubectl drain <node name> --delete-local-data --force --ignore-daemonsets
kubectl delete node <node name>

Then, on the node being removed, reset all kubeadm installed state:

kubeadm reset

e.which doesn't work in IE try e.keyCode, also you probably want to use keydown() instead of keypress() if you are targeting IE.

See http://unixpapa.com/js/key.html for more information.

Edited for clarity:

This will work to to get the value if the remote.origin.url is in the form protocol://auth_info@git_host:port/project/repo.git. If you find it doesn't work, adjust the -f5 option that is part of the first cut command.

For the example remote.origin.url of protocol://auth_info@git_host:port/project/repo.git the output created by the cut command would contain the following:

-f1: protocol: -f2: (blank) -f3: auth_info@git_host:port -f4: project -f5: repo.git

If you are having problems, look at the output of the git config --get remote.origin.url command to see which field contains the original repository. If the remote.origin.url does not contain the .git string then omit the pipe to the second cut command.

#!/usr/bin/env bash
repoSlug="$(git config --get remote.origin.url | cut -d/ -f5 | cut -d. -f1)"
echo ${repoSlug}

Use type = "button" instead of "submit", then add an onClick handler for it.

For example:

<input type="button" value="Increment" onClick="myVar++;" />

If you want to do some high-powered debugging, you can subscribe to every change of the state and pause the app to see what's going on in detail as follows.

store.subscribe( () => {
  console.log('state\n', store.getState());
  debugger;
});

Place that in the file where you do createStore.

To copy the state object from the console to the clipboard, follow these steps:

1. Right-click an object in Chrome's console and select Store as Global Variable from the context menu. It will return something like temp1 as the variable name.

2. Chrome also has a copy() method, so copy(temp1) in the console should copy that object to your clipboard.

https://stackoverflow.com/a/25140576

https://scottwhittaker.net/chrome-devtools/2016/02/29/chrome-devtools-copy-object.html

You can view the object in a json viewer like this one: http://jsonviewer.stack.hu/

You can compare two json objects here: http://www.jsondiff.com/

WARNING: git clean -f will remove untracked files, meaning they're gone for good since they aren't stored in the repository. Make sure you really want to remove all untracked files before doing this.

Try this and see git clean -f.

git reset --hard will not remove untracked files, where as git-clean will remove any files from the tracked root directory that are not under Git tracking.

Alternatively, as @Paul Betts said, you can do this (beware though - that removes all ignored files too)

• git clean -df
• git clean -xdf CAUTION! This will also delete ignored files

Well, your code is not reproducible so we will never know for sure, but this is what help('break')says:

break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.

So yes, break only breaks the current loop. You can also see it in action with e.g.:

for (i in 1:10)
{
    for (j in 1:10)
    {
        for (k in 1:10)
        {
            cat(i," ",j," ",k,"\n")
            if (k ==5) break
        }   
    }
}

If need to find nested in some dirs:

find / -type f -wholename "*dirname/filename"

Or connected dirs:

find / -type d -wholename "*foo/bar"

The general belief is that you shouldn't be using background images for things with meaningful semantic value so there isn't really a proper way to store alt data with those images. The important question is what are you going to be doing with that alt data? Do you want it to display if the images don't load? Do you need it for some programmatic function on the page? You could store the data arbitrarily using made up css properties that have no meaning (might cause errors?) OR by adding in hidden images that have the image and the alt tag, and then when you need a background images alt you can compare the image paths and then handle the data however you want using some custom script to simulate what you need. There's no way I know of to make the browser automatically handle some sort of alt attribute for background images though.

I got this error because the user account that TFS Build Service was running under did not have permissions to write to the destination folder. Right-click on the folder-->Properties-->Security.

This is from : Script to change password on linux servers over ssh

The script below will need to be saved as a file (eg ./passwdWrapper) and made executable (chmod u+x ./passwdWrapper)

#!/usr/bin/expect -f
#wrapper to make passwd(1) be non-interactive
#username is passed as 1st arg, passwd as 2nd

set username [lindex $argv 0]
set password [lindex $argv 1]
set serverid [lindex $argv 2]
set newpassword [lindex $argv 3]

spawn ssh $serverid passwd
expect "assword:"
send "$password\r"
expect "UNIX password:"
send "$password\r"
expect "password:"
send "$newpassword\r"
expect "password:"
send "$newpassword\r"
expect eof

Then you can run ./passwdWrapper $user $password $server $newpassword which will actually change the password.

Note: This requires that you install expect on the machine from which you will be running the command. (sudo apt-get install expect) The script works on CentOS 5/6 and Ubuntu 14.04, but if the prompts in passwd change, you may have to tweak the expect lines.

Quick Description of AJAX

AJAX is simply Asyncronous JSON or XML (in most newer situations JSON). Because we are doing an ASYNC task we will likely be providing our users with a more enjoyable UI experience. In this specific case we are doing a FORM submission using AJAX.

Really quickly there are 4 general web actions GET, POST, PUT, and DELETE; these directly correspond with SELECT/Retreiving DATA, INSERTING DATA, UPDATING/UPSERTING DATA, and DELETING DATA. A default HTML/ASP.Net webform/PHP/Python or any other form action is to "submit" which is a POST action. Because of this the below will all describe doing a POST. Sometimes however with http you might want a different action and would likely want to utilitize .ajax.

My code specifically for you (described in code comments):

/* attach a submit handler to the form */
$("#formoid").submit(function(event) {

  /* stop form from submitting normally */
  event.preventDefault();

  /* get the action attribute from the <form action=""> element */
  var $form = $(this),
    url = $form.attr('action');

  /* Send the data using post with element id name and name2*/
  var posting = $.post(url, {
    name: $('#name').val(),
    name2: $('#name2').val()
  });

  /* Alerts the results */
  posting.done(function(data) {
    $('#result').text('success');
  });
  posting.fail(function() {
    $('#result').text('failed');
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

<form id="formoid" action="studentFormInsert.php" title="" method="post">
  <div>
    <label class="title">First Name</label>
    <input type="text" id="name" name="name">
  </div>
  <div>
    <label class="title">Last Name</label>
    <input type="text" id="name2" name="name2">
  </div>
  <div>
    <input type="submit" id="submitButton" name="submitButton" value="Submit">
  </div>
</form>

<div id="result"></div>

Documentation

From jQuery website $.post documentation.

Example: Send form data using ajax requests

$.post("test.php", $("#testform").serialize());

Example: Post a form using ajax and put results in a div

<!DOCTYPE html>

            <input type="submit" value="Search" />
        </form>
        <!-- the result of the search will be rendered inside this div -->
        <div id="result"></div>
        <script>

                event.preventDefault();

                /* get some values from elements on the page: */
                var $form = $(this),
                    term = $form.find('input[name="s"]').val(),
                    url = $form.attr('action');

                /* Send the data using post */
                var posting = $.post(url, {
                    s: term
                });

                /* Put the results in a div */
                posting.done(function(data) {
                    var content = $(data).find('#content');
                    $("#result").empty().append(content);
                });
            });

Without using OAuth or at minimum HTTPS (TLS/SSL) please don't use this method for secure data (credit card numbers, SSN, anything that is PCI, HIPAA, or login related)

@Override
public void onBackPressed() {
    super.onBackPressed();
}

and if you want on button click go back then simply put

        onBackPressed();
    }
});

I ran into the same problem. My fix was changing <parameter value="v12.0" /> to <parameter value="mssqllocaldb" /> into the "app.config" file.

I had a similar problems, till I got it working. Below is the full listing of the integration:

1. Generate public/private keys pair: ssh-keygen -t rsa

2. Copy the public key (~/.ssh/id_rsa.pub) and paste it in Bitbucket SSH keys, in user’s account management console:

3. Copy the private key (~/.ssh/id_rsa) to new user (or even existing one) with private key credentials, in this case, username will not make a difference, so username can be anything:

4. run this command to test if you can get access to Bitbucket account: ssh -T [email protected]

5. OPTIONAL: Now, you can use your git to to copy repo to your desk without passwjord git clone [email protected]:username/repo_name.git

6. Now you can enable Bitbucket hooks for Jenkins push notifications and automatic builds, you will do that in 2 steps:

   1. Add an authentication token inside the job/project you configure, it can be anything:

   2. In Bitbucket hooks: choose jenkins hooks, and fill the fields as below:

Where:

**End point**: username:usertoken@jenkins_domain_or_ip
**Project name**: is the name of job you created on Jenkins
**Token**: Is the authorization token you added in the above steps in your Jenkins' job/project 

Recommendation: I usually add the usertoken as the authorization Token (in both Jenkins Auth Token job configuration and Bitbucket hooks), making them one variable to ease things on myself.

In theory, yes, as long as you don't exceed the maximum url and/oor query string length for the client or server.

In practice, things can get a bit trickier. For example, it can trigger an HttpRequestValidationException on ASP.NET if the value happens to contain an "on" and you leave in the trailing "==".

Here some basic explanation of hibernate cache...

First level cache is associated with “session” object. The scope of cache objects is of session. Once session is closed, cached objects are gone forever. First level cache is enabled by default and you can not disable it. When we query an entity first time, it is retrieved from database and stored in first level cache associated with hibernate session. If we query same object again with same session object, it will be loaded from cache and no sql query will be executed. The loaded entity can be removed from session using evict() method. The next loading of this entity will again make a database call if it has been removed using evict() method. The whole session cache can be removed using clear() method. It will remove all the entities stored in cache.

Second level cache is apart from first level cache which is available to be used globally in session factory scope. second level cache is created in session factory scope and is available to be used in all sessions which are created using that particular session factory. It also means that once session factory is closed, all cache associated with it die and cache manager also closed down. Whenever hibernate session try to load an entity, the very first place it look for cached copy of entity in first level cache (associated with particular hibernate session). If cached copy of entity is present in first level cache, it is returned as result of load method. If there is no cached entity in first level cache, then second level cache is looked up for cached entity. If second level cache has cached entity, it is returned as result of load method. But, before returning the entity, it is stored in first level cache also so that next invocation to load method for entity will return the entity from first level cache itself, and there will not be need to go to second level cache again. If entity is not found in first level cache and second level cache also, then database query is executed and entity is stored in both cache levels, before returning as response of load() method.

What you're asking is not possible. There is no mechanism in .Net that would set all references to some object to null.

And I think that the fact that you're trying to do this indicates some sort of design problem. You should probably think about the underlying problem and solve it in another way (the other answers here suggest some options).

If the input value gets populated by a script that has some latency involved (e.g. AJAX call) then you need to wait until the input has been populated. E.g.

var w = new WebDriverWait(WebBrowser, TimeSpan.FromSeconds(10));
            w.Until((d) => {
                // Wait until the input has a value...

                var elements = d.FindElements(By.Name(name));

                var ele = elements.SingleOrDefault();

                if (ele != null)
                {
                    // Found a single element

                    if (ele.GetAttribute("value") != "")
                    {
                        // We have a value now
                        return true;
                    }
                }

                return false;
                });

        var e = WebBrowser.Current.FindElement(By.Name(name));

        if (e.GetAttribute("value") != value)
        {
            Assert.Fail("Result contains a field named '{0}', but its value is '{1}', not '{2}' as expected", name, e.GetAttribute("value"), value);
        }

Character set conversion is done implicitly on the database connection level. You can force automatic conversion off in the ODBC or ADODB connection string with the parameter "Auto Translate=False". This is NOT recommended. See: https://msdn.microsoft.com/en-us/library/ms130822.aspx

There has been a codepage incompatibility in SQL Server 2005 when Database and Client codepage did not match. https://support.microsoft.com/kb/KbView/904803

SQL-Management Console 2008 and upwards is a UNICODE application. All values entered or requested are interpreted as such on the application level. Conversation to and from the column collation is done implicitly. You can verify this with:

SELECT CAST(N'±' as varbinary(10)) AS Result

This will return 0xB100 which is the Unicode character U+00B1 (as entered in the Management Console window). You cannot turn off "Auto Translate" for Management Studio.

If you specify a different collation in the select, you eventually end up in a double conversion (with possible data loss) as long as "Auto Translate" is still active. The original character is first transformed to the new collation during the select, which in turn gets "Auto Translated" to the "proper" application codepage. That's why your various COLLATION tests still show all the same result.

You can verify that specifying the collation DOES have an effect in the select, if you cast the result as VARBINARY instead of VARCHAR so the SQL Server transformation is not invalidated by the client before it is presented:

SELECT cast(columnName COLLATE SQL_Latin1_General_CP850_BIN2 as varbinary(10)) from tableName
SELECT cast(columnName COLLATE SQL_Latin1_General_CP1_CI_AS as varbinary(10)) from tableName

This will get you 0xF1 or 0xB1 respectively if columnName contains just the character '±'

You still might get the correct result and yet a wrong character, if the font you are using does not provide the proper glyph.

Please double check the actual internal representation of your character by casting the query to VARBINARY on a proper sample and verify whether this code indeed corresponds to the defined database collation SQL_Latin1_General_CP850_BIN2

SELECT CAST(columnName as varbinary(10)) from tableName

Differences in application collation and database collation might go unnoticed as long as the conversion is always done the same way in and out. Troubles emerge as soon as you add a client with a different collation. Then you might find that the internal conversion is unable to match the characters correctly.

All that said, you should keep in mind that Management Studio usually is not the final reference when interpreting result sets. Even if it looks gibberish in MS, it still might be the correct output. The question is whether the records show up correctly in your applications.

This solution does not need any extra lib and it also fires things up when the user presses enter:

const debounce = (fn, delay) => {
    let timer = null;
    return function() {
        const context = this,
        args = arguments;
        clearTimeout(timer);
        timer = setTimeout(() => {
            fn.apply(context, args);
        }, delay);
    };  
}

const [search, setSearch] = useState('');
const [searchFor, setSearchFor] = useState(search);

useEffect(() => {
    console.log("Search:", searchFor);
}, [searchFor]);

const fireChange = event => {
    const { keyCode } = event;
    if (keyCode === 13) {
        event.preventDefault();
        setSearchFor(search);
    }
}

const changeSearch = event => {
    const { value } = event.target;
    setSearch(value);
    debounceSetSearchFor(value);
};

const debounceSetSearchFor = useCallback(debounce(function(value) {
    setSearchFor(value);
}, 250), []);

and the input could be like:

<input value={search} onKeyDown={fireChange} onChange={changeSearch}  />

I used this a little example and it worked.

$('#date').datetimepicker({
    defaultDate: new Date()
});

demo : http://jsfiddle.net/m2fjw57b/1/

if you are on linux, edit the /etc/php/php.ini (or you will have to create a new extension import file at /etc/php5/cli/conf.d) file so that you add the imap shared object file and then, restart the apache server. Uncomment

;extension=imap.so

so that it becomes like this:

extension=imap.so

Then, restart the apache by

# /etc/rc.d/httpd restart

Test with a setTimeout, that worked for me and I could submit my form, refers to this answer https://stackoverflow.com/a/779785/5510314

$(document).ready(function () {
    $("#btnSubmit").click(function () {
        setTimeout(function () { disableButton(); }, 0);
    });

    function disableButton() {
        $("#btnSubmit").prop('disabled', true);
    }
});

if anyone else need the solution

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == android.R.id.home) {
        onBackPressed();
    }

    return super.onOptionsItemSelected(item);
}

I wasn't completely happy by the --allow-file-access-from-files solution, because I'm using Chrome as my primary browser, and wasn't really happy with this breach I was opening.

Now I'm using Canary ( the chrome beta version ) for my development with the flag on. And the mere Chrome version for my real blogging : the two browser don't share the flag !

create a batch-file with the following code:

dir %1 /b /a-d > list.txt

Then drag & drop a directory on it and the files inside the directory will be listed in list.txt

Try this

 <div class="home-component" 
 [style.width.px]="width" 
 [style.height.px]="height">Some stuff in this div</div>

[Updated]: To set in % use

[style.height.%]="height">Some stuff in this div</div>

Don't use $(document).ready() just put the script directly in the head section of the page. Pages are processed top to bottom so things at the top are processed first.

Answering myself as the FAQ of this site encourages it. This works for me:

Mostly characters äåö are not a problematic as the default character set used by browsers and tomcat/java for webapps is latin1 ie. ISO-8859-1 which "understands" those characters.

To get UTF-8 working under Java+Tomcat+Linux/Windows+Mysql requires the following:

Configuring Tomcat's server.xml

It's necessary to configure that the connector uses UTF-8 to encode url (GET request) parameters:

<Connector port="8080" maxHttpHeaderSize="8192"
 maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
 enableLookups="false" redirectPort="8443" acceptCount="100"
 connectionTimeout="20000" disableUploadTimeout="true" 
 compression="on" 
 compressionMinSize="128" 
 noCompressionUserAgents="gozilla, traviata" 
 compressableMimeType="text/html,text/xml,text/plain,text/css,text/ javascript,application/x-javascript,application/javascript"
 URIEncoding="UTF-8"
/>

The key part being URIEncoding="UTF-8" in the above example. This quarantees that Tomcat handles all incoming GET parameters as UTF-8 encoded. As a result, when the user writes the following to the address bar of the browser:

 https://localhost:8443/ID/Users?action=search&name=*?*

the character ? is handled as UTF-8 and is encoded to (usually by the browser before even getting to the server) as %D0%B6.

POST request are not affected by this.

CharsetFilter

Then it's time to force the java webapp to handle all requests and responses as UTF-8 encoded. This requires that we define a character set filter like the following:

package fi.foo.filters;

import javax.servlet.*;
import java.io.IOException;

public class CharsetFilter implements Filter {

    private String encoding;

    public void init(FilterConfig config) throws ServletException {
        encoding = config.getInitParameter("requestEncoding");
        if (encoding == null) encoding = "UTF-8";
    }

    public void doFilter(ServletRequest request, ServletResponse response, FilterChain next)
            throws IOException, ServletException {
        // Respect the client-specified character encoding
        // (see HTTP specification section 3.4.1)
        if (null == request.getCharacterEncoding()) {
            request.setCharacterEncoding(encoding);
        }

        // Set the default response content type and encoding
        response.setContentType("text/html; charset=UTF-8");
        response.setCharacterEncoding("UTF-8");

        next.doFilter(request, response);
    }

    public void destroy() {
    }
}

This filter makes sure that if the browser hasn't set the encoding used in the request, that it's set to UTF-8.

The other thing done by this filter is to set the default response encoding ie. the encoding in which the returned html/whatever is. The alternative is to set the response encoding etc. in each controller of the application.

This filter has to be added to the web.xml or the deployment descriptor of the webapp:

 <!--CharsetFilter start--> 

  <filter>
    <filter-name>CharsetFilter</filter-name>
    <filter-class>fi.foo.filters.CharsetFilter</filter-class>
      <init-param>
        <param-name>requestEncoding</param-name>
        <param-value>UTF-8</param-value>
      </init-param>
  </filter>

  <filter-mapping>
    <filter-name>CharsetFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

The instructions for making this filter are found at the tomcat wiki (http://wiki.apache.org/tomcat/Tomcat/UTF-8)

JSP page encoding

In your web.xml, add the following:

<jsp-config>
    <jsp-property-group>
        <url-pattern>*.jsp</url-pattern>
        <page-encoding>UTF-8</page-encoding>
    </jsp-property-group>
</jsp-config>

Alternatively, all JSP-pages of the webapp would need to have the following at the top of them:

 <%@page pageEncoding="UTF-8" contentType="text/html; charset=UTF-8"%>

If some kind of a layout with different JSP-fragments is used, then this is needed in all of them.

HTML-meta tags

JSP page encoding tells the JVM to handle the characters in the JSP page in the correct encoding. Then it's time to tell the browser in which encoding the html page is:

This is done with the following at the top of each xhtml page produced by the webapp:

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
   <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="fi">
   <head>
   <meta http-equiv='Content-Type' content='text/html; charset=UTF-8' />
   ...

JDBC-connection

When using a db, it has to be defined that the connection uses UTF-8 encoding. This is done in context.xml or wherever the JDBC connection is defiend as follows:

      <Resource name="jdbc/AppDB" 
        auth="Container"
        type="javax.sql.DataSource"
        maxActive="20" maxIdle="10" maxWait="10000"
        username="foo"
        password="bar"
        driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/      ID_development?useEncoding=true&amp;characterEncoding=UTF-8"
    />

MySQL database and tables

The used database must use UTF-8 encoding. This is achieved by creating the database with the following:

   CREATE DATABASE `ID_development` 
   /*!40100 DEFAULT CHARACTER SET utf8 COLLATE utf8_swedish_ci */;

Then, all of the tables need to be in UTF-8 also:

   CREATE TABLE  `Users` (
    `id` int(10) unsigned NOT NULL auto_increment,
    `name` varchar(30) collate utf8_swedish_ci default NULL
    PRIMARY KEY  (`id`)
   ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_swedish_ci ROW_FORMAT=DYNAMIC;

The key part being CHARSET=utf8.

MySQL server configuration

MySQL serveri has to be configured also. Typically this is done in Windows by modifying my.ini -file and in Linux by configuring my.cnf -file. In those files it should be defined that all clients connected to the server use utf8 as the default character set and that the default charset used by the server is also utf8.

   [client]
   port=3306
   default-character-set=utf8

   [mysql]
   default-character-set=utf8

Mysql procedures and functions

These also need to have the character set defined. For example:

   DELIMITER $$

   DROP FUNCTION IF EXISTS `pathToNode` $$
   CREATE FUNCTION `pathToNode` (ryhma_id INT) RETURNS TEXT CHARACTER SET utf8
   READS SQL DATA
   BEGIN

    DECLARE path VARCHAR(255) CHARACTER SET utf8;

   SET path = NULL;

   ...

   RETURN path;

   END $$

   DELIMITER ;

GET requests: latin1 and UTF-8

If and when it's defined in tomcat's server.xml that GET request parameters are encoded in UTF-8, the following GET requests are handled properly:

   https://localhost:8443/ID/Users?action=search&name=Petteri
   https://localhost:8443/ID/Users?action=search&name=?

Because ASCII-characters are encoded in the same way both with latin1 and UTF-8, the string "Petteri" is handled correctly.

The Cyrillic character ? is not understood at all in latin1. Because Tomcat is instructed to handle request parameters as UTF-8 it encodes that character correctly as %D0%B6.

If and when browsers are instructed to read the pages in UTF-8 encoding (with request headers and html meta-tag), at least Firefox 2/3 and other browsers from this period all encode the character themselves as %D0%B6.

The end result is that all users with name "Petteri" are found and also all users with the name "?" are found.

But what about äåö?

HTTP-specification defines that by default URLs are encoded as latin1. This results in firefox2, firefox3 etc. encoding the following

    https://localhost:8443/ID/Users?action=search&name=*Päivi*

in to the encoded version

    https://localhost:8443/ID/Users?action=search&name=*P%E4ivi*

In latin1 the character ä is encoded as %E4. Even though the page/request/everything is defined to use UTF-8. The UTF-8 encoded version of ä is %C3%A4

The result of this is that it's quite impossible for the webapp to correly handle the request parameters from GET requests as some characters are encoded in latin1 and others in UTF-8. Notice: POST requests do work as browsers encode all request parameters from forms completely in UTF-8 if the page is defined as being UTF-8

Important Note

mysql supports the Basic Multilingual Plane using 3-byte UTF-8 characters. If you need to go outside of that (certain alphabets require more than 3-bytes of UTF-8), then you either need to use a flavor of VARBINARY column type or use the utf8mb4 character set (which requires MySQL 5.5.3 or later). Just be aware that using the utf8 character set in MySQL won't work 100% of the time.

Tomcat with Apache

One more thing If you are using Apache + Tomcat + mod_JK connector then you also need to do following changes:

1. Add URIEncoding="UTF-8" into tomcat server.xml file for 8009 connector, it is used by mod_JK connector. <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" URIEncoding="UTF-8"/>
2. Goto your apache folder i.e. /etc/httpd/conf and add AddDefaultCharset utf-8 in httpd.conf file. Note: First check that it is exist or not. If exist you may update it with this line. You can add this line at bottom also.

New Answer

Docker Compose has been updated. They now have a version 2 file format.

Version 2 files are supported by Compose 1.6.0+ and require a Docker Engine of version 1.10.0+.

They now support the networking feature of Docker which when run sets up a default network called myapp_default

From their documentation your file would look something like the below:

version: '2'

services:
  web:
    build: .
    ports:
      - "8000:8000"
  fpm:
    image: phpfpm
  nginx
    image: nginx

As these containers are automatically added to the default myapp_default network they would be able to talk to each other. You would then have in the Nginx config:

fastcgi_pass fpm:9000;

Also as mentioned by @treeface in the comments remember to ensure PHP-FPM is listening on port 9000, this can be done by editing /etc/php5/fpm/pool.d/www.conf where you will need listen = 9000.

Old Answer

I have kept the below here for those using older version of Docker/Docker compose and would like the information.

I kept stumbling upon this question on google when trying to find an answer to this question but it was not quite what I was looking for due to the Q/A emphasis on docker-compose (which at the time of writing only has experimental support for docker networking features). So here is my take on what I have learnt.

Docker has recently deprecated its link feature in favour of its networks feature

Therefore using the Docker Networks feature you can link containers by following these steps. For full explanations on options read up on the docs linked previously.

First create your network

docker network create --driver bridge mynetwork

Next run your PHP-FPM container ensuring you open up port 9000 and assign to your new network (mynetwork).

docker run -d -p 9000 --net mynetwork --name php-fpm php:fpm

The important bit here is the --name php-fpm at the end of the command which is the name, we will need this later.

Next run your Nginx container again assign to the network you created.

docker run --net mynetwork --name nginx -d -p 80:80 nginx:latest

For the PHP and Nginx containers you can also add in --volumes-from commands etc as required.

Now comes the Nginx configuration. Which should look something similar to this:

server {
    listen 80;
    server_name localhost;

    root /path/to/my/webroot;

    index index.html index.htm index.php;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass php-fpm:9000; 
        fastcgi_index index.php;
        include fastcgi_params;
    }

Notice the fastcgi_pass php-fpm:9000; in the location block. Thats saying contact container php-fpm on port 9000. When you add containers to a Docker bridge network they all automatically get a hosts file update which puts in their container name against their IP address. So when Nginx sees that it will know to contact the PHP-FPM container you named php-fpm earlier and assigned to your mynetwork Docker network.

You can add that Nginx config either during the build process of your Docker container or afterwards its up to you.

• Right click the database in Object Explorer.
• Choose the option "Tasks" / "Deploy Database to SQL Azure".
• In the step named "Deployment Settings", select your local database connection.
• "Next" / "Next" / "Finish"...

The only way to deal with this non-intrusively is to:

1. Spawn each worker process such that its log goes to a different file descriptor (to disk or to pipe.) Ideally, all log entries should be timestamped.
2. Your controller process can then do one of the following:
   • If using disk files: Coalesce the log files at the end of the run, sorted by timestamp
   • If using pipes (recommended): Coalesce log entries on-the-fly from all pipes, into a central log file. (E.g., Periodically select from the pipes' file descriptors, perform merge-sort on the available log entries, and flush to centralized log. Repeat.)

You can use std::find

bool found = (std::find(my_list.begin(), my_list.end(), my_var) != my_list.end());

You need to include <algorithm>. It should work on standard containers, vectors lists, etc...

I have no experience with Git, but I have with Mercurial which is also a distributed VCS. It depends on the project really, but in our case a distributed VCS suited the project as basically eliminated frequent broken builds.

I think it depends on the project really, as some are better suited towards a client-server VCS, and others towads a distributed one.

You can set the figure size if you explicitly create the figure with

plt.figure(figsize=(3,4))

You need to set figure size before calling plt.plot() To change the format of the saved figure just change the extension in the file name. However, I don't know if any of matplotlib backends support tiff

If you are using 5.6 php,

sudo apt-get install php5.6-curl

If you want to assert that the two lists are identical, don't complicate things with Hamcrest:

assertEquals(expectedList, actual.getList());

If you really intend to perform an order-insensitive comparison, you can call the containsInAnyOrder varargs method and provide values directly:

assertThat(actual.getList(), containsInAnyOrder("item1", "item2"));

(Assuming that your list is of String, rather than Agent, for this example.)

If you really want to call that same method with the contents of a List:

assertThat(actual.getList(), containsInAnyOrder(expectedList.toArray(new String[expectedList.size()]));

Without this, you're calling the method with a single argument and creating a Matcher that expects to match an Iterable where each element is a List. This can't be used to match a List.

That is, you can't match a List<Agent> with a Matcher<Iterable<List<Agent>>, which is what your code is attempting.

You can use ternary expression. There are two ways to do this:

<div ng-style="myVariable > 100 ? {'color': 'red'} : {'color': 'blue'}"></div>

or...

<div ng-style="{'color': (myVariable > 100) ? 'red' : 'blue' }"></div>

It's not possible to save content to the website using only client-side scripting such as JavaScript and jQuery, but by submitting the data in an AJAX POST request you could perform the other half very easily on the server-side.

However, I would not recommend having raw content such as scripts so easily writeable to your hosting as this could easily be exploited. If you want to learn more about AJAX POST requests, you can read the jQuery API page:

http://api.jquery.com/jQuery.post/

And here are some things you ought to be aware of if you still want to save raw script files on your hosting. You have to be very careful with security if you are handling files like this!

File uploading (most of this applies if sending plain text too if javascript can choose the name of the file) http://www.developershome.com/wap/wapUpload/wap_upload.asp?page=security https://www.owasp.org/index.php/Unrestricted_File_Upload

Another way to do this is to use the Ruby on Rails debugger. There's a Ruby on Rails guide about debugging at http://guides.rubyonrails.org/debugging_rails_applications.html

Basically, start the server with the -u option:

./script/server -u

And then insert a breakpoint into your script where you would like to have access to the controllers, helpers, etc.

class EventsController < ApplicationController
  def index
    debugger
  end
end

And when you make a request and hit that part in the code, the server console will return a prompt where you can then make requests, view objects, etc. from a command prompt. When finished, just type 'cont' to continue execution. There are also options for extended debugging, but this should at least get you started.

The link you gave does actually describe the differences, but it's buried at the bottom of the page:

Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.

The conversion could be to normalize \r\n to \n (or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.

public static void mulptiTransfer(WebDriver driver, By dropdownID, String text, By to)
{   
    String valuetext = null;
    WebElement element = locateElement(driver, dropdownID, 10);
    Select select = new Select(element);
    List<WebElement> options = element.findElements(By.tagName("option"));
    for (WebElement value: options) 
    {
        valuetext = value.getText();
        if (valuetext.equalsIgnoreCase(text))
        {
            try
            {
                select.selectByVisibleText(valuetext);
                locateElement(driver, to, 5).click();                           
                break;
            }
            catch (Exception e)
            {
                System.out.println(valuetext + "Value not found in Dropdown to Select");
            }       
        }
    }
}

Relative imports (as in from .. import mymodule) only work in a package. To import 'mymodule' that is in the parent directory of your current module:

import os,sys,inspect
currentdir = os.path.dirname(os.path.abspath(inspect.getfile(inspect.currentframe())))
parentdir = os.path.dirname(currentdir)
sys.path.insert(0,parentdir) 

import mymodule

edit: the __file__ attribute is not always given. Instead of using os.path.abspath(__file__) I now suggested using the inspect module to retrieve the filename (and path) of the current file

Your code contains two problems:

• The equality operator in JavaScript is ==, not =.
• jQuery.text() joins all text nodes of matched elements into a single string. If you have two successive elements, of which the first contains 'some' and the second contains 'Text', then your code will incorrectly think that there exists an element that contains 'someText'.

I suggest the following instead:

if ($('#field > div.field-item:contains("someText")').length > 0) {
    $("#somediv").addClass("thisClass");
}

You can easily do it by calling this method :

public static Bitmap RotateImage(Image image, float angle)
{
    if (image == null)
        throw new ArgumentNullException("image");

    PointF offset = new PointF((float)image.Width / 2, (float)image.Height / 2);

    //create a new empty bitmap to hold rotated image
    Bitmap rotatedBmp = new Bitmap(image.Width, image.Height);
    rotatedBmp.SetResolution(image.HorizontalResolution, image.VerticalResolution);

    //make a graphics object from the empty bitmap
    Graphics g = Graphics.FromImage(rotatedBmp);

    //Put the rotation point in the center of the image
    g.TranslateTransform(offset.X, offset.Y);

    //rotate the image
    g.RotateTransform(angle);

    //move the image back
    g.TranslateTransform(-offset.X, -offset.Y);

    //draw passed in image onto graphics object
    g.DrawImage(image, new PointF(0, 0));

    return rotatedBmp;
}

don't forget to add a reference to System.Drawing.dll on your project

Example of this method call :

Image image = new Bitmap("waves.png");
Image newImage = RotateImage(image, 360);
newImage.Save("newWaves.png");

you have to use capital True and False not true and false

You can hijack your Android audio port using an Arduino board like this. Then, you have two options (as far as I'm concerned):

1) Buy another Arduino Shield that supports RFID. I haven't seen one that supports UHF so far.

2) Try to connect your Arduino hijack with a USB RFID reader and build some embedded hardware kit.

Right now, I'm working in the second option but with iPhone.

I'm not properly answering the question but, I think it makes sense to clear why we should specify the radix.

On MDN documentation we can read that:

If radix is undefined or 0 (or absent), JavaScript assumes the following:

• [...]
• If the input string begins with "0", radix is eight (octal) or 10 (decimal). Exactly which radix is chosen is implementation-dependent. ECMAScript 5 specifies that 10 (decimal) is used, but not all browsers support this yet. For this reason always specify a radix when using parseInt.
• [...]

For modern reference, in Symfony 2.4+, you cannot name the arguments for the Constructor Injection method anymore. According to the documentation You would pass in:

services:
    test.common.userservice:
        class:  Test\CommonBundle\Services\UserService
        arguments: [ "@doctrine.orm.entity_manager" ]

And then they would be available in the order they were listed via the arguments (if there are more than 1).

public function __construct(EntityManager $entityManager) {
    $this->em = $entityManager;
}

Actually there is. There is a static method valueOf in the java.sql.Date object which does exactly that. So we have

java.util.Date date = java.sql.Date.valueOf(localDate);

and that's it. No explicit setting of time zones because the local time zone is taken implicitly.

From docs:

The provided LocalDate is interpreted as the local date in the local time zone.

The java.sql.Date subclasses java.util.Date so the result is a java.util.Date also.

And for the reverse operation there is a toLocalDate method in the java.sql.Date class. So we have:

LocalDate ld = new java.sql.Date(date.getTime()).toLocalDate();

With your example:

avgDists = np.array([1, 8, 6, 9, 4])

Obtain indexes of n maximal values:

ids = np.argpartition(avgDists, -n)[-n:]

Sort them in descending order:

ids = ids[np.argsort(avgDists[ids])[::-1]]

Obtain results (for n=4):

>>> avgDists[ids]
array([9, 8, 6, 4])

It has to do with the Normal Form for the SQL language. IF statements can, by definition, only take a single SQL statement. However, there is a special kind of SQL statement which can contain multiple SQL statements, the BEGIN-END block.

If you omit the BEGIN-END block, your SQL will run fine, but it will only execute the first statement as part of the IF.

Basically, this:

IF @Term = 3
    INSERT INTO @Classes
    SELECT              
        XXXXXX  
    FROM XXXX blah blah blah

is equivalent to the same thing with the BEGIN-END block, because you are only executing a single statement. However, for the same reason that not including the curly-braces on an IF statement in a C-like language is a bad idea, it is always preferable to use BEGIN and END.

Here is a brief pointer on void pointers: https://www.learncpp.com/cpp-tutorial/613-void-pointers/

6.13 — Void pointers

Because the void pointer does not know what type of object it is pointing to, it cannot be dereferenced directly! Rather, the void pointer must first be explicitly cast to another pointer type before it is dereferenced.

If a void pointer doesn't know what it's pointing to, how do we know what to cast it to? Ultimately, that is up to you to keep track of.

Void pointer miscellany

It is not possible to do pointer arithmetic on a void pointer. This is because pointer arithmetic requires the pointer to know what size object it is pointing to, so it can increment or decrement the pointer appropriately.

Assuming the machine's memory is byte-addressable and does not require aligned accesses, the most generic and atomic (closest to the machine level representation) way of interpreting a void* is as a pointer-to-a-byte, uint8_t*. Casting a void* to a uint8_t* would allow you to, for example, print out the first 1/2/4/8/however-many-you-desire bytes starting at that address, but you can't do much else.

uint8_t* byte_p = (uint8_t*)p;
for (uint8_t* i = byte_p; i < byte_p + 8; i++) {
  printf("%x ",*i);
}

try this once.

$wp_query->set_404();
status_header(404);
get_template_part('404'); 

In C++, there is only a subtle difference. It's a holdover from C, in which it makes a difference.

The C language standard (C89 §3.1.2.3, C99 §6.2.3, and C11 §6.2.3) mandates separate namespaces for different categories of identifiers, including tag identifiers (for struct/union/enum) and ordinary identifiers (for typedef and other identifiers).

If you just said:

struct Foo { ... };
Foo x;

you would get a compiler error, because Foo is only defined in the tag namespace.

You'd have to declare it as:

struct Foo x;

Any time you want to refer to a Foo, you'd always have to call it a struct Foo. This gets annoying fast, so you can add a typedef:

struct Foo { ... };
typedef struct Foo Foo;

Now struct Foo (in the tag namespace) and just plain Foo (in the ordinary identifier namespace) both refer to the same thing, and you can freely declare objects of type Foo without the struct keyword.

The construct:

typedef struct Foo { ... } Foo;

is just an abbreviation for the declaration and typedef.

Finally,

typedef struct { ... } Foo;

declares an anonymous structure and creates a typedef for it. Thus, with this construct, it doesn't have a name in the tag namespace, only a name in the typedef namespace. This means it also cannot be forward-declared. If you want to make a forward declaration, you have to give it a name in the tag namespace.

In C++, all struct/union/enum/class declarations act like they are implicitly typedef'ed, as long as the name is not hidden by another declaration with the same name. See Michael Burr's answer for the full details.

One option is using Object.keys():

Object.keys(driversCounter)

It works fine for modern browsers (however, Internet Explorer supports it starting from version 9 only).

To add compatible support you can copy the code snippet provided in MDN.

The first thing you need to know is that HashSet acts like a Set, which means you add your object directly to the HashSet and it cannot contain duplicates. You just add your value directly in HashSet.

However, HashMap is a Map type. That means every time you add an entry, you add a key-value pair.

In HashMap you can have duplicate values, but not duplicate keys. In HashMap the new entry will replace the old one. The most recent entry will be in the HashMap.

Understanding Link between HashMap and HashSet:

Remember, HashMap can not have duplicate keys. Behind the scene HashSet uses a HashMap.

When you attempt to add any object into a HashSet, this entry is actually stored as a key in the HashMap - the same HashMap that is used behind the scene of HashSet. Since this underlying HashMap needs a key-value pair, a dummy value is generated for us.

Now when you try to insert another duplicate object into the same HashSet, it will again attempt to be insert it as a key in the HashMap lying underneath. However, HashMap does not support duplicates. Hence, HashSet will still result in having only one value of that type. As a side note, for every duplicate key, since the value generated for our entry in HashSet is some random/dummy value, the key is not replaced at all. it will be ignored as removing the key and adding back the same key (the dummy value is the same) would not make any sense at all.

Summary:

HashMap allows duplicate values, but not keys. HashSet cannot contains duplicates.

To play with whether the addition of an object is successfully completed or not, you can check the boolean value returned when you call .add() and see if it returns true or false. If it returned true, it was inserted.

With angular 6 and rxjs 6 Observable.throw(), Observable.off() has been deprecated instead you need to use throwError

ex :

return this.http.get('yoururl')
  .pipe(
    map(response => response.json()),
    catchError((e: any) =>{
      //do your processing here
      return throwError(e);
    }),
  );

I suggest that you give an if to the div than:

$("#my_div_id").html();

The serial port communication programs moserial or gtkterm provide an easy way to check connectivity and modify /dev/ttyUSB0 (or /dev/ttyUSB1!) settings. Even though there maybe only a single USB to RS232 adapter, the n designation /dev/ttyUSBn can and does change periodically! Both moserial and gtkterm will show what port designation is relevant in their respective pull down menus when selecting an appropriate port to use.

The list selector drawable is a StateListDrawable — it contains reference to multiple drawables for each state the list can be, like selected, focused, pressed, disabled...

While you can retrieve the drawable using getSelector(), I don't believe you can retrieve a specific Drawable from a StateListDrawable, nor does it seem possible to programmatically retrieve the colour directly from a ColorDrawable anyway.

As for setting the colour, you need a StateListDrawable as described above. You can set this on your list using the android:listSelector attribute, defining the drawable in XML like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
  <item android:state_enabled="false" android:state_focused="true"
        android:drawable="@drawable/item_disabled" />
  <item android:state_pressed="true"
        android:drawable="@drawable/item_pressed" />
  <item android:state_focused="true"
        android:drawable="@drawable/item_focused" />
</selector>

Another recursive approach:

# change directory to target folder:
cd /Volumes/path/to/folder

# find all things of type "f" (file), 
# then pipe "|" each result as an argument (xargs -0) 
# to the "xattr -c" command:
find . -type f -print0 | xargs -0 xattr -c

# Sometimes you may have to use a star * instead of the dot.
# The dot just means "here" (whereever your cd'd to
find * -type f -print0 | xargs -0 xattr -c

Beware of circular references when DOM objects are involved:

Memory leak patterns in JavaScript

Keep in mind that memory can only be reclaimed when there are no active references to the object. This is a common pitfall with closures and event handlers, as some JS engines will not check which variables actually are referenced in inner functions and just keep all local variables of the enclosing functions.

Here's a simple example:

function init() {
    var bigString = new Array(1000).join('xxx');
    var foo = document.getElementById('foo');
    foo.onclick = function() {
        // this might create a closure over `bigString`,
        // even if `bigString` isn't referenced anywhere!
    };
}

A naive JS implementation can't collect bigString as long as the event handler is around. There are several ways to solve this problem, eg setting bigString = null at the end of init() (delete won't work for local variables and function arguments: delete removes properties from objects, and the variable object is inaccessible - ES5 in strict mode will even throw a ReferenceError if you try to delete a local variable!).

I recommend to avoid unnecessary closures as much as possible if you care for memory consumption.

What happens if I promote the column to be a/the PK, too (a.k.a. identifying relationship)? As the column is now the PK, I must tag it with @Id (...).

This enhanced support of derived identifiers is actually part of the new stuff in JPA 2.0 (see the section 2.4.1 Primary Keys Corresponding to Derived Identities in the JPA 2.0 specification), JPA 1.0 doesn't allow Id on a OneToOne or ManyToOne. With JPA 1.0, you'd have to use PrimaryKeyJoinColumn and also define a Basic Id mapping for the foreign key column.

Now the question is: are @Id + @JoinColumn the same as just @PrimaryKeyJoinColumn?

You can obtain a similar result but using an Id on OneToOne or ManyToOne is much simpler and is the preferred way to map derived identifiers with JPA 2.0. PrimaryKeyJoinColumn might still be used in a JOINED inheritance strategy. Below the relevant section from the JPA 2.0 specification:

11.1.40 PrimaryKeyJoinColumn Annotation

The PrimaryKeyJoinColumn annotation specifies a primary key column that is used as a foreign key to join to another table.

The PrimaryKeyJoinColumn annotation is used to join the primary table of an entity subclass in the JOINED mapping strategy to the primary table of its superclass; it is used within a SecondaryTable annotation to join a secondary table to a primary table; and it may be used in a OneToOne mapping in which the primary key of the referencing entity is used as a foreign key to the referenced entity^[108].

...

If no PrimaryKeyJoinColumn annotation is specified for a subclass in the JOINED mapping strategy, the foreign key columns are assumed to have the same names as the primary key columns of the primary table of the superclass.

...

Example: Customer and ValuedCustomer subclass

@Entity
@Table(name="CUST")
@Inheritance(strategy=JOINED)
@DiscriminatorValue("CUST")
public class Customer { ... }

@Entity
@Table(name="VCUST")
@DiscriminatorValue("VCUST")
@PrimaryKeyJoinColumn(name="CUST_ID")
public class ValuedCustomer extends Customer { ... }

_{[108] The derived id mechanisms described in section 2.4.1.1 are now to be preferred over PrimaryKeyJoinColumn for the OneToOne mapping case.}

This source http://weblogs.java.net/blog/felipegaucho/archive/2009/10/24/jpa-join-table-additional-state states that using @ManyToOne and @Id works with JPA 1.x. Who's correct now?

The author is using a pre release JPA 2.0 compliant version of EclipseLink (version 2.0.0-M7 at the time of the article) to write an article about JPA 1.0(!). This article is misleading, the author is using something that is NOT part of JPA 1.0.

For the record, support of Id on OneToOne and ManyToOne has been added in EclipseLink 1.1 (see this message from James Sutherland, EclipseLink comitter and main contributor of the Java Persistence wiki book). But let me insist, this is NOT part of JPA 1.0.

I would use a library to create your JSON String for you. Some options are:

• GSON
• Crockford's lib

This will make dealing with escaping much easier. An example (using org.json) would be:

JSONObject obj = new JSONObject();

obj.put("id", userID);
obj.put("type", methoden);
obj.put("msg", msget);

// etc.

final String json = obj.toString(); // <-- JSON string

This may also be useful: {{ form.field.as_hidden }}

This may be a 'special' case but was fiddling with this piece of code:

ForceType application/x-httpd-php SetHandler application/x-httpd-php

As a quick test for extentionless file handling, when a similar problem occurred.

Some but not all php files thereafter treated the css files as php and thus succesfully loaded the css but not handled it as css, thus zero rules were executed when checking f12 style editor.

Perhaps something similar might occur to any-one else here and this tidbit might help.

REPLACE(<your xml column>,'&',chr(38)||'amp;')

Use the npm bin command to get the node modules /bin directory of your project

$ $(npm bin)/<binary-name> [args]

e.g.

$ $(npm bin)/bower install

Without any third-party tools and any app, you can find unused CSS and javascript by using chrome dev tools in the coverage tab. read the post below from google developers. chrome coverage tab

Just remove the "px" in the style.height assignation, like:

<button type="button" onClick = "document.getElementById('chartdiv').style.height = 200px"> </button>

Should be

<button type="button" onClick = "document.getElementById('chartdiv').style.height = 200">Click Me!</button>

Your code does not work because it is not doing what you are expecting it to do. Switch blocks take in a value, and compare each case to the given value, looking for equality. Your comparison value is an integer, but most of your case expressions resolve to a boolean value.

So, for example, say liCount = 2. Your first case will not match, because 2 != 0. Your second case, (liCount<=5 && liCount>0) evaluates to true, but 2 != true, so this case will not match either.

For this reason, as many others have said, you should use a series of if...then...else if blocks to do this.

GRANT SELECT ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password';

This will create a user with SELECT privilege for all database including Views.

Try the -Force parameter:

New-Item -ItemType Directory -Force -Path C:\Path\That\May\Or\May\Not\Exist

You can use Test-Path -PathType Container to check first.

See the New-Item MSDN help article for more details.

I also tried to use CURRVAL, in my case to find out if some process inserted new rows to some table with that sequence as Primary Key. My assumption was that CURRVAL would be the fastest method. But a) CurrVal does not work, it will just get the old value because you are in another Oracle session, until you do a NEXTVAL in your own session. And b) a select max(PK) from TheTable is also very fast, probably because a PK is always indexed. Or select count(*) from TheTable. I am still experimenting, but both SELECTs seem fast.

I don't mind a gap in a sequence, but in my case I was thinking of polling a lot, and I would hate the idea of very large gaps. Especially if a simple SELECT would be just as fast.

Conclusion:

• CURRVAL is pretty useless, as it does not detect NEXTVAL from another session, it only returns what you already knew from your previous NEXTVAL
• SELECT MAX(...) FROM ... is a good solution, simple and fast, assuming your sequence is linked to that table

function liReplace(replacement) {
    $(".dropit-submenu li").each(function() {
        var t = $(this);
        t.html(t.html().replace(replacement, "*" + replacement + "*"));
        t.children(":first").html(t.children(":first").html().replace(replacement, "*" +` `replacement + "*"));
        t.children(":first").html(t.children(":first").html().replace(replacement + " ", ""));
        alert(t.children(":first").text());
    });
}

• First code find a title replace t.html(t.html()
• Second code a text replace t.children(":first")

Sample <a title="alpc" href="#">alpc</a>

a short summary:

track by is used in order to link your data with the DOM generation (and mainly re-generation) made by ng-repeat.

when you add track by you basically tell angular to generate a single DOM element per data object in the given collection

this could be useful when paging and filtering, or any case where objects are added or removed from ng-repeat list.

usually, without track by angular will link the DOM objects with the collection by injecting an expando property - $$hashKey - into your JavaScript objects, and will regenerate it (and re-associate a DOM object) with every change.

full explanation:

http://www.bennadel.com/blog/2556-using-track-by-with-ngrepeat-in-angularjs-1-2.htm

a more practical guide:

http://www.codelord.net/2014/04/15/improving-ng-repeat-performance-with-track-by/

(track by is available in angular > 1.2 )

First two columns and 5 rows

if you want to read settings from the DLL's config file but not from the the root applications web.config or app.config use below code to read configuration in the dll.

var appConfig = ConfigurationManager.OpenExeConfiguration(Assembly.GetExecutingAssembly().Location);
string dllConfigData = appConfig.AppSettings.Settings["dllConfigData"].Value;

To clarify, you should use HTTP error codes where they fit with the protocol, and not use HTTP status codes to send business logic errors.

Errors like insufficient balance, no cabs available, bad user/password qualify for HTTP status 200 with application specific error handling in the response body.

See this software engineering answer:

I would say it is better to be explicit about the separation of protocols. Let the HTTP server and the web browser do their own thing, and let the app do its own thing. The app needs to be able to make requests, and it needs the responses--and its logic as to how to request, how to interpret the responses, can be more (or less) complex than the HTTP perspective.

I'm not so comfortable with regular expressions, and my example results from a datetimepicker field formatted m/d/Y h:mA. In this legal example, you have to arrive before the actual deposition hearing. I use replace function to clean up the dates so that I can process them as Date objects and compare them.

function compareDateTimes() {
    //date format ex "04/20/2017 01:30PM"
    //the problem is that this format results in Invalid Date
    //var d0 = new Date("04/20/2017 01:30PM"); => Invalid Date

    var start_date = $(".letter #depo_arrival_time").val();
    var end_date = $(".letter #depo_dateandtime").val();

    if (start_date=="" || end_date=="") {
        return;
    }
    //break it up for processing
    var d1 = stringToDate(start_date);
    var d2 = stringToDate(end_date);

    var diff = d2.getTime() - d1.getTime();
    if (diff < 0) {
        end_date = moment(d2).format("MM/DD/YYYY hh:mA");
        $(".letter #depo_arrival_time").val(end_date);
    }
}

function stringToDate(the_date) {
    var arrDate = the_date.split(" ");
    var the_date = arrDate[0];
    var the_time = arrDate[1];
    var arrTime = the_time.split(":");
    var blnPM = (arrTime[1].indexOf("PM") > -1);
    //first fix the hour
    if (blnPM) {
        if (arrTime[0].indexOf("0")==0) {
            var clean_hour = arrTime[0].substr(1,1);
            arrTime[0] = Number(clean_hour) + 12;
        }
        arrTime[1] = arrTime[1].replace("PM", ":00");
    } else {
        arrTime[1] = arrTime[1].replace("AM", ":00");
    }
    var date_object =  new Date(the_date);
    //now replace the time
    date_object = String(date_object).replace("00:00:00", arrTime.join(":"));
    date_object =  new Date(date_object);

    return date_object;
}

very simple answer

Here is a property I use in one of my applications

public List<string> OperationModes
{
    get
    {
       return Enum.GetNames(typeof(SomeENUM)).ToList();
    }
}

Are you meaning?

data2 <- data1[good,]

With

data1[good]

you're selecting columns in a wrong way (using a logical vector of complete rows).

Consider that parameter pollutant is not used; is it a column name that you want to extract? if so it should be something like

data2 <- data1[good, pollutant]

Furthermore consider that you have to rbind the data.frames inside the for loop, otherwise you get only the last data.frame (its completed.cases)

And last but not least, i'd prefer generating filenames eg with

id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")

A little modified chunk of ?sprintf

The string fmt (in our case "%3d") contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through .... The allowed conversion specifications start with a % and end with one of the letters in the set aAdifeEgGosxX%. These letters denote the following types:

• d: integer

Eg a more general example

    sprintf("I am %10d years old", 25)
[1] "I am         25 years old"
          ^^^^^^^^^^

if your application uses threads directly or indirectly (i.e. behind the scene like in a 3rd-party library) it is absolutely common to have threads terminate after they are done... which is basically what you describe... the debugger shows this message... you can configure the debugger to not display this message if you don't want it...

If the above does not help then please provide more details since I am not sure what exactly the problem is you face...

Related to how to link to the README.md of a GitHub repository to a specific line number of code

You have three cases:

1. We can link to (custom commit)

   But Link will ALWAYS link to old file version, which will NOT contains new updates in the master branch for example. Example:

   https://github.com/username/projectname/blob/b8d94367354011a0470f1b73c8f135f095e28dd4/file.txt#L10
   

2. We can link to (custom branch) like (master-branch). But the link will ALWAYS link to the latest file version which will contain new updates. Due to new updates, the link may point to an invalid business line number. Example:

   https://github.com/username/projectname/blob/master/file.txt#L10
   

3. GitHub can NOT make AUTO-link to any file either to (custom commit) nor (master-branch) Because of following business issues:

   • line business meaning, to link to it in the new file
   • length of target highlighted code which can be changed

1. Import Android Parcelable code generator

2. Create a class

public class Sample {
    int id;
    String name;
}

3. Generate > Parcelable from menu

Done.

For firefox links appear to be "special". The only way I was able to get this working was to use the createEvent described here on MDN and call the initMouseEvent function. Even that didn't work completely, I had to manually tell the browser to open a link...

var theEvent = document.createEvent("MouseEvent");
theEvent.initMouseEvent("click", true, true, window, 0, 0, 0, 0, 0, false, false, false, false, 0, null);
var element = document.getElementById('link');
element.dispatchEvent(theEvent);

while (element)
{
    if (element.tagName == "A" && element.href != "")
    {
        if (element.target == "_blank") { window.open(element.href, element.target); }
        else { document.location = element.href; }
        element = null;
    }
    else
    {
        element = element.parentElement;
    }
}

You should analyze your style.css file, possibly using Developer Tools in your favorite browser, to see which rule sets font size on the element in a manner that overrides the one in a style attribute. Apparently, it has to be one using the !important specifier, which generally indicates poor logic and structure in styling.

Primarily, modify the style.css file so that it does not use !important. Failing this, add !important to the rule in style attribute. But you should aim at reducing the use of !important, not increasing it.

Yes, your secret key appears to be missing. Without it, you will not be able to decrypt the files.

Do you have the key backed up somewhere?

Re-creating the keys, whether you use the same passphrase or not, will not work. Each key pair is unique.

I had this issue after upgrading Android Studio to 3.2 and even upgrade some SDK-Packages.

The cause was that the path to emulator had changed, so don't use ...../Android/Sdk/tools/emulator but instead ....../Android/Sdk/emulator/emulator.

Try this one, with code coloration:

http://labs.swelen.com/tools/javascript/beauty.html

Binary Search

You can use Collections.binarySearch to search an element in your list (assuming the list is sorted):

Collections.binarySearch(list, new YourObject("a1", "b",
                "c"), new Comparator<YourObject>() {

            @Override
            public int compare(YourObject o1, YourObject o2) {
                return o1.getName().compareTo(o2.getName());
            }
        });

which will return a negative number if the object is not present in the collection or else it will return the index of the object. With this you can search for objects with different searching strategies.

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.

In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.

Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.

Since it is really a formatting issue when displaying the date (e.g. displays in local time), I like to use the new(ish) Intl.DateTimeFormat object to perform the formatting as it is more explicit and provides more output options:

const dateOptions = { timeZone: 'UTC', month: 'long', day: 'numeric', year: 'numeric' };

const dateFormatter = new Intl.DateTimeFormat('en-US', dateOptions);
const dateAsFormattedString = dateFormatter.format(new Date('2019-06-01T00:00:00.000+00:00'));

console.log(dateAsFormattedString) // "June 1, 2019"

As shown, by setting the timeZone to 'UTC' it will not perform local conversions. As a bonus, it also allows you to create more polished outputs. You can read more about the Intl.DateTimeFormat object from Mozilla - Intl.DateTimeFormat.

Edit:

The same functionality can be achieved without creating a new Intl.DateTimeFormat object. Simply pass the locale and date options directly into the toLocaleDateString() function.

const dateOptions = { timeZone: 'UTC', month: 'long', day: 'numeric', year: 'numeric' };
const myDate = new Date('2019-06-01T00:00:00.000+00:00');
today.toLocaleDateString('en-US', dateOptions); // "June 1, 2019"

let ar = ['a', 'b', 'c', 'd'];

function change( old_array, old_index , new_index ){

  return old_array.map(( item , index, array )=>{
    if( index === old_index ) return array[ new_index ];
    else if( index === new_index ) return array[ old_index ];
    else return item;
  });

}

let result = change( ar, 0, 1 );

console.log( result );

result:

["b", "a", "c", "d"]

In recent versions of Git you can add multiple pushurls for a given remote. Use the following to add two pushurls to your origin:

git remote set-url --add --push origin git://original/repo.git
git remote set-url --add --push origin git://another/repo.git

So when you push to origin, it will push to both repositories.

UPDATE 1: Git 1.8.0.1 and 1.8.1 (and possibly other versions) seem to have a bug that causes --add to replace the original URL the first time you use it, so you need to re-add the original URL using the same command. Doing git remote -v should reveal the current URLs for each remote.

UPDATE 2: Junio C. Hamano, the Git maintainer, explained it's how it was designed. Doing git remote set-url --add --push <remote_name> <url> adds a pushurl for a given remote, which overrides the default URL for pushes. However, you may add multiple pushurls for a given remote, which then allows you to push to multiple remotes using a single git push. You can verify this behavior below:

$ git clone git://original/repo.git
$ git remote -v
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.'
remote.origin.url=git://original/repo.git
remote.origin.fetch=+refs/heads/*:refs/remotes/origin/*

Now, if you want to push to two or more repositories using a single command, you may create a new remote named all (as suggested by @Adam Nelson in comments), or keep using the origin, though the latter name is less descriptive for this purpose. If you still want to use origin, skip the following step, and use origin instead of all in all other steps.

So let's add a new remote called all that we'll reference later when pushing to multiple repositories:

$ git remote add all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)               <-- ADDED
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git            <-- ADDED
remote.all.fetch=+refs/heads/*:refs/remotes/all/* <-- ADDED

Then let's add a pushurl to the all remote, pointing to another repository:

$ git remote set-url --add --push all git://another/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)                 <-- CHANGED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git         <-- ADDED

Here git remote -v shows the new pushurl for push, so if you do git push all master, it will push the master branch to git://another/repo.git only. This shows how pushurl overrides the default url (remote.all.url).

Now let's add another pushurl pointing to the original repository:

$ git remote set-url --add --push all git://original/repo.git
$ git remote -v
all git://original/repo.git (fetch)
all git://another/repo.git (push)
all git://original/repo.git (push)                <-- ADDED
origin  git://original/repo.git (fetch)
origin  git://original/repo.git (push)
$ git config -l | grep '^remote\.all'
remote.all.url=git://original/repo.git
remote.all.fetch=+refs/heads/*:refs/remotes/all/*
remote.all.pushurl=git://another/repo.git
remote.all.pushurl=git://original/repo.git        <-- ADDED

You see both pushurls we added are kept. Now a single git push all master will push the master branch to both git://another/repo.git and git://original/repo.git.

Try with regex \d:

$words = preg_replace('/\d/', '', $words );

\d is an equivalent for [0-9] which is an equivalent for numbers range from 0 to 9.
