Instead of create the new Container class you can use a dataTable.

DataTable dt = new DataTable();
dt.Columns.Add("My first column Name");

dt.Rows.Add(new object[] { "Item 1" });
dt.Rows.Add(new object[] { "Item number 2" });
dt.Rows.Add(new object[] { "Item number three" });

myDataGridView.DataSource = dt;

More about this problem you can find here: http://psworld.pl/Programming/BindingListOfString

I've also tried to use

<span></span>

but

<a></a> 

Here you are:

<button type="button" class="btn btn-danger" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="bottom" data-bs-content="Some word here">
<a data-bs-toggle="tooltip" title="Example">Some info here</a>
</button>

Even better, try to wrap the entire button (that uses popover) with a div:

<div data-bs-toggle="tooltip" title="Something">
<button type="button" class="btn btn-danger" data-bs-container="body" data-bs-toggle="popover" data-bs-placement="bottom" data-bs-content="Some word here">
Button label
</button>
</div>

I ran into a similar problem where I have a dependency property that I wanted the class to listen to change events to grab related data from a service.

public static readonly DependencyProperty CustomerProperty = 
    DependencyProperty.Register("Customer", typeof(Customer),
        typeof(CustomerDetailView),
        new PropertyMetadata(OnCustomerChangedCallBack));

public Customer Customer {
    get { return (Customer)GetValue(CustomerProperty); }
    set { SetValue(CustomerProperty, value); }
}

private static void OnCustomerChangedCallBack(
        DependencyObject sender, DependencyPropertyChangedEventArgs e)
{
    CustomerDetailView c = sender as CustomerDetailView;
    if (c != null) {
        c.OnCustomerChanged();
    }
}

protected virtual void OnCustomerChanged() {
    // Grab related data.
    // Raises INotifyPropertyChanged.PropertyChanged
    OnPropertyChanged("Customer");
}

I ran into a similar limitation with DataTriggers, and it would seem that you can only check for equality. The closest thing I've seen that might help you is a technique for doing other types of comparisons other than equality.

This blog post describes how to do comparisons such as LT, GT, etc in a DataTrigger.

This limitation of the DataTrigger can be worked around to some extent by using a Converter to massage the data into a special value you can then compare against, as suggested in Robert Macnee's answer.

Turns out all I needed to do was wrap the left-hand side of the expression in soft brackets:

<span class="gallery-date">{{(gallery.date | date:'mediumDate') || "Various"}}</span>

The correct solution seems to be:

<Window.Resources>
    <CollectionViewSource x:Key="ItemsCVS" Source="{Binding MyItems}" />
</Window.Resources>
<!-- ... -->
<DataGrid ItemsSource="{Binding MyRecords}">
    <DataGridComboBoxColumn Header="Column With Predefined Values"
                            ItemsSource="{Binding Source={StaticResource ItemsCVS}}"
                            SelectedValueBinding="{Binding MyItemId}"
                            SelectedValuePath="Id"
                            DisplayMemberPath="StatusCode" />
</DataGrid>

The layout above works perfectly fine for me, and should work for others. This design choice also makes sense, though it isn't very well explained anywhere. But if you have a data column with predefined values, those values typically don't change during run-time. So creating a CollectionViewSource and initializing the data once makes sense. It also gets rid of the longer bindings to find an ancestor and bind on it's data context (which always felt wrong to me).

I am leaving this here for anyone else who struggled with this binding, and wondered if there was a better way (As this page is obviously still coming up in search results, that's how I got here).

For an attribute value that needs to be interpolated in a directive that is not using an isolated scope, e.g.,

<input my-directive value="{{1+1}}">

use Attributes' method $observe:

myApp.directive('myDirective', function () {
  return function (scope, element, attr) {
    attr.$observe('value', function(actual_value) {
      element.val("value = "+ actual_value);
    })
 }
});

From the directive page,

observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.

If the attribute value is just a constant, e.g.,

<input my-directive value="123">

you can use $eval if the value is a number or boolean, and you want the correct type:

return function (scope, element, attr) {
   var number = scope.$eval(attr.value);
   console.log(number, number + 1);
});

If the attribute value is a string constant, or you want the value to be string type in your directive, you can access it directly:

return function (scope, element, attr) {
   var str = attr.value;
   console.log(str, str + " more");
});

In your case, however, since you want to support interpolated values and constants, use $observe.

Be aware of the single quotes for the string format. This doesn't work:

    Content="{Binding PlannedDateTime, StringFormat={}{0:yy.MM.dd HH:mm}}"

while this does:

    Content="{Binding PlannedDateTime, StringFormat='{}{0:yy.MM.dd HH:mm}'}"

Without seeing said object list, I believe you should be binding to the DataGrid's ItemsSource property, not its DataContext.

<DataGrid x:Name="Imported" VerticalAlignment="Top" ItemsSource="{Binding Source=list}"  AutoGenerateColumns="False" CanUserResizeColumns="True">
    <DataGrid.Columns>                
        <DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
        <DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
   </DataGrid.Columns>
</DataGrid>

(This assumes that the element [UserControl, etc.] that contains the DataGrid has its DataContext bound to an object that contains the list collection. The DataGrid is derived from ItemsControl, which relies on its ItemsSource property to define the collection it binds its rows to. Hence, if list isn't a property of an object bound to your control's DataContext, you might need to set both DataContext={Binding list} and ItemsSource={Binding list} on the DataGrid...)

List does not implement IBindingList so the grid does not know about your new items.

Bind your DataGridView to a BindingList<T> instead.

var list = new BindingList<Person>(persons);
myGrid.DataSource = list;

But I would even go further and bind your grid to a BindingSource

var list = new List<Person>()
{
    new Person { Name = "Joe", },
    new Person { Name = "Misha", },
};
var bindingList = new BindingList<Person>(list);
var source = new BindingSource(bindingList, null);
grid.DataSource = source;

First of all, two things that we need to understand,

Client

• It makes request to a specific server

bindService(new Intent("com.android.vending.billing.InAppBillingService.BIND"), mServiceConn, Context.BIND_AUTO_CREATE);

here mServiceConn is instance of ServiceConnection class(inbuilt) it is actually interface that we need to implement with two (1st for network connected and 2nd network not connected) method to monitor network connection state.

Server

• It handles the request of the client and makes replica of its own which is private to client only who send request and this raplica of server runs on different thread.

Now at client side, how to access all the methods of server?

• Server sends response with IBinder Object. So, IBinder object is our handler which accesses all the methods of Service by using (.) operator.

.

MyService myService;
public ServiceConnection myConnection = new ServiceConnection() {
    public void onServiceConnected(ComponentName className, IBinder binder) {
        Log.d("ServiceConnection","connected");
        myService = binder;
    }
    //binder comes from server to communicate with method's of 

    public void onServiceDisconnected(ComponentName className) {
        Log.d("ServiceConnection","disconnected");
        myService = null;
    }
}

Now how to call method which lies in service

myservice.serviceMethod();

Here myService is object and serviceMethod is method in service. and by this way communication is established between client and server.

I know it's way way overdue, but I have an alternative solution, which is lighter and simpler. Derive a class from System.Windows.Controls.RadioButton and declare two dependency properties RadioValue and RadioBinding. Then in the class code, override OnChecked and set the RadioBinding property value to that of the RadioValue property value. In the other direction, trap changes to the RadioBinding property using a callback, and if the new value is equal to the value of the RadioValue property, set its IsChecked property to true.

Here's the code:

public class MyRadioButton : RadioButton
{
    public object RadioValue
    {
        get { return (object)GetValue(RadioValueProperty); }
        set { SetValue(RadioValueProperty, value); }
    }

    // Using a DependencyProperty as the backing store for RadioValue.
       This enables animation, styling, binding, etc...
    public static readonly DependencyProperty RadioValueProperty =
        DependencyProperty.Register(
            "RadioValue", 
            typeof(object), 
            typeof(MyRadioButton), 
            new UIPropertyMetadata(null));

    public object RadioBinding
    {
        get { return (object)GetValue(RadioBindingProperty); }
        set { SetValue(RadioBindingProperty, value); }
    }

    // Using a DependencyProperty as the backing store for RadioBinding.
       This enables animation, styling, binding, etc...
    public static readonly DependencyProperty RadioBindingProperty =
        DependencyProperty.Register(
            "RadioBinding", 
            typeof(object), 
            typeof(MyRadioButton), 
            new FrameworkPropertyMetadata(
                null, 
                FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, 
                OnRadioBindingChanged));

    private static void OnRadioBindingChanged(
        DependencyObject d,
        DependencyPropertyChangedEventArgs e)
    {
        MyRadioButton rb = (MyRadioButton)d;
        if (rb.RadioValue.Equals(e.NewValue))
            rb.SetCurrentValue(RadioButton.IsCheckedProperty, true);
    }

    protected override void OnChecked(RoutedEventArgs e)
    {
        base.OnChecked(e);
        SetCurrentValue(RadioBindingProperty, RadioValue);
    }
}

XAML usage:

<my:MyRadioButton GroupName="grp1" Content="Value 1"
    RadioValue="val1" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 2"
    RadioValue="val2" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 3"
    RadioValue="val3" RadioBinding="{Binding SelectedValue}"/>
<my:MyRadioButton GroupName="grp1" Content="Value 4"
    RadioValue="val4" RadioBinding="{Binding SelectedValue}"/>

Hope someone finds this useful after all this time :)

Wherever there is errors or exceptions in static blocks, this exception will be thrown. To get the cause of this exception simply use Throwable.getCause() to know what is wrong.

You assigned a string "Red". Your Background property should be of type Color:

using System.Windows;
using System.ComponentModel;

namespace TestBackground88238
{
    public partial class Window1 : Window, INotifyPropertyChanged
    {

        #region ViewModelProperty: Background
        private Color _background;
        public Color Background
        {
            get
            {
                return _background;
            }

            set
            {
                _background = value;
                OnPropertyChanged("Background");
            }
        }
        #endregion

        //...//
}

Then you can use the binding to the SolidColorBrush like this:

public Window1()
{
    InitializeComponent();
    DataContext = this;

    Background = Colors.Red;
    Message = "This is the title, the background should be " + Background.toString() + ".";

}

not 100% sure about the .toString() method on Color-Object. It might tell you it is a Color-Class, but you will figur this out ;)

I know this is a way late, but I thought I'd add yet another way of doing this.

You can take advantage of the fact that the Text property can be set using "Runs", so you can set up multiple bindings using a Run for each one. This is useful if you don't have access to MultiBinding (which I didn't find when developing for Windows Phone)

<TextBlock>
  <Run Text="Name = "/>
  <Run Text="{Binding Name}"/>
  <Run Text=", Id ="/>
  <Run Text="{Binding Id}"/>
</TextBlock>

Make your property "windowname" a DependencyProperty and keep the remaining same.

This is common issue, another way is to use DataTable object

DataTable dt = new DataTable();
dt.Columns.Add("column name");

dt.Rows.Add(new object[] { "Item 1" });
dt.Rows.Add(new object[] { "Item 2" });
dt.Rows.Add(new object[] { "Item 3" });

This problem is described in detail here: http://www.psworld.pl/Programming/BindingListOfString

I had a similar problem where the SelectedItem-binding did not update when I selected something in the combobox. My problem was that I had to set UpdateSourceTrigger=PropertyChanged for the binding.

<ComboBox ItemsSource="{Binding SalesPeriods}" 
          SelectedItem="{Binding SelectedItem, UpdateSourceTrigger=PropertyChanged}" />

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

There's also the WPF Converters project on Codeplex. In their documentation they say you can use their MapConverter to convert from Visibility enumeration to bool

<Label>
    <Label.Visible>
        <Binding Path="IsVisible">
            <Binding.Converter>
                <con:MapConverter>
                    <con:Mapping From="True" To="{x:Static Visibility.Visible}"/>
                    <con:Mapping From="False" To="{x:Static Visibility.Hidden}"/>
                </con:MapConverter>
            </Binding.Converter>
        </Binding>
    </Label.Visible>
</Label>

Just a tiny bit of info that might help others; if you do something along the lines of searching all assemblies in some directory for classes that inherit/implement classes/interfaces, then make sure you clean out stale assemblies if you get this error pertaining to one of your own assemblies.

The scenario would be something like:

1. Assembly A loads all assemblies in some folder
2. Assembly B in this folder is stale, but references assembly C
3. Assembly C exists, but namespaces, class names or some other detail might have changed in the time that has passed since assembly B became stale (in my case a namespace was changed through a refactoring process)

In short: A ---loads--> B (stale) ---references---> C

If this happens, the only telltale sign is the namespace and classname in the error message. Examine it closely. If you can't find it anywhere in your solution, you are likely trying to load a stale assembly.

There newer ways to connect Node.js and C++. Please, loot at Nan.

EDIT The fastest and easiest way is nbind. If you want to write asynchronous add-on you can combine Asyncworker class from nan.

How does it work?

When a JSF view (Facelets/JSP file) get built/restored, a JSF component tree will be produced. At that moment, the view build time, all binding attributes are evaluated (along with id attribtues and taghandlers like JSTL). When the JSF component needs to be created before being added to the component tree, JSF will check if the binding attribute returns a precreated component (i.e. non-null) and if so, then use it. If it's not precreated, then JSF will autocreate the component "the usual way" and invoke the setter behind binding attribute with the autocreated component instance as argument.

In effects, it binds a reference of the component instance in the component tree to a scoped variable. This information is in no way visible in the generated HTML representation of the component itself. This information is in no means relevant to the generated HTML output anyway. When the form is submitted and the view is restored, the JSF component tree is just rebuilt from scratch and all binding attributes will just be re-evaluated like described in above paragraph. After the component tree is recreated, JSF will restore the JSF view state into the component tree.

Component instances are request scoped!

Important to know and understand is that the concrete component instances are effectively request scoped. They're newly created on every request and their properties are filled with values from JSF view state during restore view phase. So, if you bind the component to a property of a backing bean, then the backing bean should absolutely not be in a broader scope than the request scope. See also JSF 2.0 specitication chapter 3.1.5:

3.1.5 Component Bindings

...

Component bindings are often used in conjunction with JavaBeans that are dynamically instantiated via the Managed Bean Creation facility (see Section 5.8.1 “VariableResolver and the Default VariableResolver”). It is strongly recommend that application developers place managed beans that are pointed at by component binding expressions in “request” scope. This is because placing it in session or application scope would require thread-safety, since UIComponent instances depends on running inside of a single thread. There are also potentially negative impacts on memory management when placing a component binding in “session” scope.

Otherwise, component instances are shared among multiple requests, possibly resulting in "duplicate component ID" errors and "weird" behaviors because validators, converters and listeners declared in the view are re-attached to the existing component instance from previous request(s). The symptoms are clear: they are executed multiple times, one time more with each request within the same scope as the component is been bound to.

And, under heavy load (i.e. when multiple different HTTP requests (threads) access and manipulate the very same component instance at the same time), you may face sooner or later an application crash with e.g. Stuck thread at UIComponent.popComponentFromEL, or Java Threads at 100% CPU utilization using richfaces UIDataAdaptorBase and its internal HashMap, or even some "strange" IndexOutOfBoundsException or ConcurrentModificationException coming straight from JSF implementation source code while JSF is busy saving or restoring the view state (i.e. the stack trace indicates saveState() or restoreState() methods and like).

Using binding on a bean property is bad practice

Regardless, using binding this way, binding a whole component instance to a bean property, even on a request scoped bean, is in JSF 2.x a rather rare use case and generally not the best practice. It indicates a design smell. You normally declare components in the view side and bind their runtime attributes like value, and perhaps others like styleClass, disabled, rendered, etc, to normal bean properties. Then, you just manipulate exactly that bean property you want instead of grabbing the whole component and calling the setter method associated with the attribute.

In cases when a component needs to be "dynamically built" based on a static model, better is to use view build time tags like JSTL, if necessary in a tag file, instead of createComponent(), new SomeComponent(), getChildren().add() and what not. See also How to refactor snippet of old JSP to some JSF equivalent?

Or, if a component needs to be "dynamically rendered" based on a dynamic model, then just use an iterator component (<ui:repeat>, <h:dataTable>, etc). See also How to dynamically add JSF components.

Composite components is a completely different story. It's completely legit to bind components inside a <cc:implementation> to the backing component (i.e. the component identified by <cc:interface componentType>. See also a.o. Split java.util.Date over two h:inputText fields representing hour and minute with f:convertDateTime and How to implement a dynamic list with a JSF 2.0 Composite Component?

Only use binding in local scope

However, sometimes you'd like to know about the state of a different component from inside a particular component, more than often in use cases related to action/value dependent validation. For that, the binding attribute can be used, but not in combination with a bean property. You can just specify an in the local EL scope unique variable name in the binding attribute like so binding="#{foo}" and the component is during render response elsewhere in the same view directly as UIComponent reference available by #{foo}. Here are several related questions where such a solution is been used in the answer:

• Validate input as required only if certain command button is pressed
• How to render a component only if another component is not rendered?
• JSF 2 dataTable row index without dataModel
• Primefaces dependent selectOneMenu and required="true"
• Validate a group of fields as required when at least one of them is filled
• How to change css class for the inputfield and label when validation fails?

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 had this same error for a while in a slightly different scenario. I had

<wpftoolkit:DataGrid
    AutoGenerateColumns="False"
    ItemsSource="{Binding Path=Accounts}" >
    <wpftoolkit:DataGridTextColumn 
        Header="Account Name" 
        Binding="{Binding Path=AccountName}" />
</wpftoolkit:DataGrid>

which I fixed to be

<wpftoolkit:DataGrid
    AutoGenerateColumns="False"
    ItemsSource="{Binding Path=Accounts}" >
    <wpftoolkit:DataGrid.Columns>
        <wpftoolkit:DataGridTextColumn 
            Header="Account Name" 
            Binding="{Binding Path=AccountName}" />
    </wpftoolkit:DataGrid.Columns>

Use Tuple in Converter, and in OnExecute, cast the parameter object back to Tuple.

public class YourConverter : IMultiValueConverter 
{      
    public object Convert(object[] values, ...)     
    {   
        Tuple<string, string> tuple = new Tuple<string, string>(
            (string)values[0], (string)values[1]);
        return (object)tuple;
    }      
} 

// ...

public void OnExecute(object parameter) 
{
    var param = (Tuple<string, string>) parameter;
}

There is a built in function to compare lists:

Following is the syntax for cmp() method -

cmp(list1, list2)

#!/usr/bin/python

list1, list2 = [123, 'xyz'], [123, 'xyz']

print cmp(list1,list2)

When we run above program, it produces following result -

0

If the result is a tie, meaning that 0 is returned

    //best way to deal with this is sqlbulkcopy 
    //but if you dont like it you can do it like this
    //read current sql table in an adapter
    //add rows of datatable , I have mentioned a simple way of it
    //and finally updating changes

    Dim cnn As New SqlConnection("connection string")        
    cnn.Open()
    Dim cmd As New SqlCommand("select * from  sql_server_table", cnn)
    Dim da As New SqlDataAdapter(cmd)       
    Dim ds As New DataSet()
    da.Fill(ds, "sql_server_table")
    Dim cb As New SqlCommandBuilder(da)        

    //for each datatable row
    ds.Tables("sql_server_table").Rows.Add(COl1, COl2)

    da.Update(ds, "sql_server_table")

You can use nircmd.exe's elevate command

NirCmd Command Reference - elevate

elevate [Program] {Command-Line Parameters}

For Windows Vista/7/2008 only: Run a program with administrator rights. When the [Program] contains one or more space characters, you must put it in quotes.

Examples:

elevate notepad.exe 
elevate notepad.exe C:\Windows\System32\Drivers\etc\HOSTS 
elevate "c:\program files\my software\abc.exe"

PS: I use it on win 10 and it works

// just use (useEffect). every change will be logged with current value
import React, { useEffect } from "react";

export function () {
  useEffect(() => {
    window.addEventListener('resize', () => {
      const myWidth  = window.innerWidth;
      console.log('my width :::', myWidth)
   })
  },[window])

  return (
    <>
      enter code here
   </>
  )
}

Don't worry... Its much easy to solve your problem. Just SET you SDK-LOCATION and JDK-LOCATION.

• Click on Configure ( As Soon Android studio open )
• Click Project Default
• Click Project Structure

• Clik Android Sdk Location

• Select & Browse your Android SDK Location (Like: C:\Android\sdk)

• Uncheck USE EMBEDDED JDK LOCATION

• Set & Browse JDK Location, Like C:\Program Files\Java\jdk1.8.0_121

The problem with creating a directory and keeping index.php in it is that

1. your links with menu will stop functioning
2. There will be way too many directories. For eg, there will be a seperate directory for each and every question here on stackoverflow

The solutions are 1. MOD REWRITE (as suggested above) 2. use a php code to dynamically include other files in index file. Read a bit more abt it here http://inobscuro.com/tutorials/read/16/

The rule is as following :

A B 

B as a descendant of A

A > B 

B as a child of A

So

            .setParameter("startDate", startDate, TemporalType.DATE)
            .setParameter("endDate", endDate, TemporalType.DATE)
            .getResultList();

}

See also: How to properly override clone method?. Cloning is broken in Java, it's so hard to get it right, and even when it does it doesn't really offer much, so it's not really worth the hassle.

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

You can call UserPrincipal.FindByIdentity inside System.DirectoryServices.AccountManagement:

using System.DirectoryServices.AccountManagement;

using (var pc = new PrincipalContext(ContextType.Domain, "MyDomainName"))
{
    var user = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, "MyDomainName\\" + userName);
}

    <item name="editTextColor">@color/white</item>
    <item name="android:textColor">@color/white</item>
    <item name="android:textColorHint">@color/gray</item>
    <item name="android:textColorPrimary">@color/gray</item>
    <item name="colorControlNormal">@color/gray</item>
    <item name="colorControlActivated">@color/white</item>
    <item name="colorControlHighlight">#30FFFFFF</item>

If you are using Angular UI Bootstrap, you can use tooltip with html syntax: tooltip-html-unsafe

e.g. update to angular 1.2.10 & angular-ui-bootstrap 0.11: http://jsfiddle.net/aX2vR/1/

You could use the encodeURIComponent to safely URL encode parts of a query string:

var array = JSON.stringify([ 'foo', 'bar' ]);
var url = 'http://example.com/?data=' + encodeURIComponent(array);

or if you are sending this as an AJAX request:

var array = JSON.stringify([ 'foo', 'bar' ]);
$.ajax({
    url: 'http://example.com/',
    type: 'GET',
    data: { data: array },
    success: function(result) {
        // process the results
    }
});

The variable names should be descriptive:

var date = new Date;
date.setTime(result_from_Date_getTime);

var seconds = date.getSeconds();
var minutes = date.getMinutes();
var hour = date.getHours();

var year = date.getFullYear();
var month = date.getMonth(); // beware: January = 0; February = 1, etc.
var day = date.getDate();

var dayOfWeek = date.getDay(); // Sunday = 0, Monday = 1, etc.
var milliSeconds = date.getMilliseconds();

The days of a given month do not change. In a leap year, February has 29 days. Inspired by http://www.javascriptkata.com/2007/05/24/how-to-know-if-its-a-leap-year/ (thanks Peter Bailey!)

Continued from the previous code:

var days_in_months = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];
// for leap years, February has 29 days. Check whether
// February, the 29th exists for the given year
if( (new Date(year, 1, 29)).getDate() == 29 ) days_in_month[1] = 29;

There is no straightforward way to get the week of a year. For the answer on that question, see Is there a way in javascript to create a date object using year & ISO week number?

Give class img-fluid to your div carousel-item.Finally it will be:

<div class="carousel-item active img-fluid">
      <img class="d-block w-100" src="path to image" alt="First slide">
</div>

First of all I can highly recommend reading the Nexus book. It will explain the benefits of using a Maven repository manager.

There is a section on how to configure your Maven build to use Nexus:

• http://www.sonatype.com/books/nexus-book/reference/config.html

This leads me to question why you altering your POM file? I suspect what you really want to do is setup Nexus as a remote repository mirror. This is done in your Maven settings file.

The following tells Maven use Nexus as your default repository (Instead of Maven Central)

<settings>
  ..
  ..
  <mirrors>
    <mirror>
      <id>nexus</id>
      <url>http://localhost:8081/nexus/content/groups/public</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
  </mirrors>

This is desired behaviour since your Nexus repository is configured to cache artifacts retrieved from Central (which is good for build performance).

Note:

• The "public" repository group could include other repositories proxied by your Nexus instance (Not just Maven Central). You probabily want this behaviour, as it centralizes all repository management. It just makes your build less portable for people outside of your organization.

I use Url.Content and never have a problem.

<script src="<%= Url.Content ("~/Scripts/jquery-1.4.1.min.js") %>" type="text/javascript"></script>

Always generate script and review before you run. Below the script

  select 'Alter table dbo.' + t.name + ' drop constraint '+ d.name  
  from sys.tables t
  join sys.default_constraints d on d.parent_object_id = t.object_id
  join sys.columns c on c.object_id = t.object_id
       and c.column_id = d.parent_column_id
  where c.name in ('VersionEffectiveDate','VersionEndDate','VersionReasonDesc')
  order by t.name

Before FontAwesome 5:

The standard declarations just contain .fa-rotate-90, .fa-rotate-180 and .fa-rotate-270. However you can easily create your own:

.fa-rotate-45 {
    -webkit-transform: rotate(45deg);
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    transform: rotate(45deg);
}

With FontAwesome 5:

You can use what’s so called “Power Transforms”. Example:

<i class="fas fa-snowman" data-fa-transform="rotate-90"></i>
<i class="fas fa-snowman" data-fa-transform="rotate-180"></i>
<i class="fas fa-snowman" data-fa-transform="rotate-270"></i>
<i class="fas fa-snowman" data-fa-transform="rotate-30"></i>
<i class="fas fa-snowman" data-fa-transform="rotate--30"></i>

You need to add the data-fa-transform attribute with the value of rotate- and your desired rotation in degrees.

Source: https://fontawesome.com/how-to-use/on-the-web/styling/power-transforms

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

I know this is old, but if anyone else wants to know why they get incomplete json like above is because the ampersand & is a special character in URLs used to separate parameters.
In your data there is an ampersand in R&R. So the acc parameter ends when it reaches the ampersand character.

That's why you are getting chopped data. The solution is either url encode the data or send as POST like the accepted solution suggests.

namespace NKUtilities 
{
    using System;
    using System.Net;

    public class DNSUtility
    {
        public static int Main (string [] args)
        {

          String strHostName = new String ("");
          if (args.Length == 0)
          {
              // Getting Ip address of local machine...
              // First get the host name of local machine.
              strHostName = Dns.GetHostName ();
              Console.WriteLine ("Local Machine's Host Name: " +  strHostName);
          }
          else
          {
              strHostName = args[0];
          }

          // Then using host name, get the IP address list..
          IPHostEntry ipEntry = DNS.GetHostByName (strHostName);
          IPAddress [] addr = ipEntry.AddressList;

          for (int i = 0; i < addr.Length; i++)
          {
              Console.WriteLine ("IP Address {0}: {1} ", i, addr[i].ToString ());
          }
          return 0;
        }    
     }
}

Use std::greater as the comparison function:

std::priority_queue<int, std::vector<int>, std::greater<int> > my_min_heap;

You can use CSS position: sticky; for the first row of the table MDN ref:

.table-class tr:first-child>td{
    position: sticky;
    top: 0;
}

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

To help understand what do $#, $0 and $1, ..., $n do, I use this script:

#!/bin/bash

for ((i=0; i<=$#; i++)); do
  echo "parameter $i --> ${!i}"
done

Running it returns a representative output:

$ ./myparams.sh "hello" "how are you" "i am fine"
parameter 0 --> myparams.sh
parameter 1 --> hello
parameter 2 --> how are you
parameter 3 --> i am fine

Why are you using a macro? Excel has Password Protection built-in. When you select File/Save As... there should be a Tools button by the Save button, click it then "General Options" where you can enter a "Password to Open" and a "Password to Modify".

How about this:

$.getJSON(_spPageContextInfo.webServerRelativeUrl + "/_api/web/currentuser")
.done(function(data){ 
    console.log(data.Title);
})
.fail(function() { console.log("Failed")});

You can float the elements (the map wrapper, and the paragraph), or use inline-block on both of them.

To checkout the branch via Jenkins scripts use:

stage('Checkout SCM') {
    git branch: 'branchName', credentialsId: 'your_credentials', url: "giturlrepo"
}

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

I came across this error when tried to start 32-bit build of Eclipse under 64-bit linux. The problem was solved after installing ia32-libs package.

If you like recursion, this might be a solution of interest to you:

def f(E):
    if E==[]: 
        return []
    elif type(E) != list: 
        return [E]
    else:
        a = f(E[0])
        b = f(E[1:])
        a.extend(b)
        return a

I actually adapted this from some practice Scheme code that I had written a while back.

Enjoy!

I’m going to hold the unpopular on SO selenium tag opinion that XPath is preferable to CSS in the longer run.

This long post has two sections - first I'll put a back-of-the-napkin proof the performance difference between the two is 0.1-0.3 milliseconds (yes; that's 100 microseconds), and then I'll share my opinion why XPath is more powerful.

Performance difference

Let's first tackle "the elephant in the room" – that xpath is slower than css.

With the current cpu power (read: anything x86 produced since 2013), even on browserstack/saucelabs/aws VMs, and the development of the browsers (read: all the popular ones in the last 5 years) that is hardly the case. The browser's engines have developed, the support of xpath is uniform, IE is out of the picture (hopefully for most of us). This comparison in the other answer is being cited all over the place, but it is very contextual – how many are running – or care about – automation against IE8?

If there is a difference, it is in a fraction of a millisecond.

Yet, most higher-level frameworks add at least 1ms of overhead over the raw selenium call anyways (wrappers, handlers, state storing etc); my personal weapon of choice – RobotFramework – adds at least 2ms, which I am more than happy to sacrifice for what it provides. A network roundtrip from an AWS us-east-1 to BrowserStack's hub is usually 11 milliseconds.

So with remote browsers if there is a difference between xpath and css, it is overshadowed by everything else, in orders of magnitude.

The measurements

There are not that many public comparisons (I've really seen only the cited one), so – here's a rough single-case, dummy and simple one.
It will locate an element by the two strategies X times, and compare the average time for that.

The target – BrowserStack's landing page, and its "Sign Up" button; a screenshot of the html as writing this post:

Here's the test code (python):

from selenium import webdriver
import timeit


if __name__ == '__main__':

    xpath_locator = '//div[@class="button-section col-xs-12 row"]'
    css_locator = 'div.button-section.col-xs-12.row'

    repetitions = 1000

    driver = webdriver.Chrome()
    driver.get('https://www.browserstack.com/')

    css_time = timeit.timeit("driver.find_element_by_css_selector(css_locator)", 
                             number=repetitions, globals=globals())
    xpath_time = timeit.timeit('driver.find_element_by_xpath(xpath_locator)', 
                             number=repetitions, globals=globals())

    driver.quit()

    print("css total time {} repeats: {:.2f}s, per find: {:.2f}ms".
          format(repetitions, css_time, (css_time/repetitions)*1000))
    print("xpath total time for {} repeats: {:.2f}s, per find: {:.2f}ms".
          format(repetitions, xpath_time, (xpath_time/repetitions)*1000))

For those not familiar with Python – it opens the page, and finds the element – first with the css locator, then with the xpath; the find operation is repeated 1,000 times. The output is the total time in seconds for the 1,000 repetitions, and average time for one find in milliseconds.

The locators are:

• for xpath – "a div element having this exact class value, somewhere in the DOM";
• the css is similar – "a div element with this class, somewhere in the DOM".

Deliberately chosen not to be over-tuned; also, the class selector is cited for the css as "the second fastest after an id".

The environment – Chrome v66.0.3359.139, chromedriver v2.38, cpu: ULV Core M-5Y10 usually running at 1.5GHz (yes, a "word-processing" one, not even a regular i7 beast).

Here's the output:

css total time 1000 repeats: 8.84s, per find: 8.84ms

xpath total time for 1000 repeats: 8.52s, per find: 8.52ms

Obviously the per find timings are pretty close; the difference is 0.32 milliseconds. Don't jump "the xpath is faster" – sometimes it is, sometimes it's css.

Let's try with another set of locators, a tiny-bit more complicated – an attribute having a substring (common approach at least for me, going after an element's class when a part of it bears functional meaning):

xpath_locator = '//div[contains(@class, "button-section")]'
css_locator = 'div[class~=button-section]'

The two locators are again semantically the same – "find a div element having in its class attribute this substring".
Here are the results:

css total time 1000 repeats: 8.60s, per find: 8.60ms

xpath total time for 1000 repeats: 8.75s, per find: 8.75ms

Diff of 0.15ms.

As an exercise - the same test as done in the linked blog in the comments/other answer - the test page is public, and so is the testing code.

They are doing a couple of things in the code - clicking on a column to sort by it, then getting the values, and checking the UI sort is correct.
I'll cut it - just get the locators, after all - this is the root test, right?

The same code as above, with these changes in:

• The url is now http://the-internet.herokuapp.com/tables; there are 2 tests.

• The locators for the first one - "Finding Elements By ID and Class" - are:

css_locator = '#table2 tbody .dues'
xpath_locator = "//table[@id='table2']//tr/td[contains(@class,'dues')]"

And here is the outcome:

css total time 1000 repeats: 8.24s, per find: 8.24ms

xpath total time for 1000 repeats: 8.45s, per find: 8.45ms

Diff of 0.2 milliseconds.

The "Finding Elements By Traversing":

css_locator = '#table1 tbody tr td:nth-of-type(4)'
xpath_locator = "//table[@id='table1']//tr/td[4]"

The result:

css total time 1000 repeats: 9.29s, per find: 9.29ms

xpath total time for 1000 repeats: 8.79s, per find: 8.79ms

This time it is 0.5 ms (in reverse, xpath turned out "faster" here).

So 5 years later (better browsers engines) and focusing only on the locators performance (no actions like sorting in the UI, etc), the same testbed - there is practically no difference between CSS and XPath.

So, out of xpath and css, which of the two to choose for performance? The answer is simple – choose locating by id.

Long story short, if the id of an element is unique (as it's supposed to be according to the specs), its value plays an important role in the browser's internal representation of the DOM, and thus is usually the fastest.

Yet, unique and constant (e.g. not auto-generated) ids are not always available, which brings us to "why XPath if there's CSS?"

The XPath advantage

With the performance out of the picture, why do I think xpath is better? Simple – versatility, and power.

Xpath is a language developed for working with XML documents; as such, it allows for much more powerful constructs than css.
For example, navigation in every direction in the tree – find an element, then go to its grandparent and search for a child of it having certain properties.
It allows embedded boolean conditions – cond1 and not(cond2 or not(cond3 and cond4)); embedded selectors – "find a div having these children with these attributes, and then navigate according to it".
XPath allows searching based on a node's value (its text) – however frowned upon this practice is, it does come in handy especially in badly structured documents (no definite attributes to step on, like dynamic ids and classes - locate the element by its text content).

The stepping in css is definitely easier – one can start writing selectors in a matter of minutes; but after a couple of days of usage, the power and possibilities xpath has quickly overcomes css.
And purely subjective – a complex css is much harder to read than a complex xpath expression.

Outro ;)

Finally, again very subjective - which one to chose?

IMO, there is no right or wrong choice - they are different solutions to the same problem, and whatever is more suitable for the job should be picked.

Being "a fan" of XPath I'm not shy to use in my projects a mix of both - heck, sometimes it is much faster to just throw a CSS one, if I know it will do the work just fine.

In the browser session you can also go to Kernel and then click Restart and Clear Output.

I found simple way, it using shift()

function waitReq(id)
{
  jQuery.ajax(
  {
    type: 'POST',
    url: ajaxurl,
    data:
    {
      "page": id
    },
    success: function(resp)
    {
      ...........
      // check array length if not "0" continue to use next array value
      if(ids.length)
      {
        waitReq(ids.shift()); // 2
      )
    },
    error: function(resp)
    {
      ....................
      if(ids.length)
      {
        waitReq(ids.shift());
      )
    }
  });
}

var ids = [1, 2, 3, 4, 5];    
// shift() = delete first array value (then print)
waitReq(ids.shift()); // print 1

The good option is to use AdminClient as below before starting to produce or consume the messages

private static final int ADMIN_CLIENT_TIMEOUT_MS = 5000;           
 try (AdminClient client = AdminClient.create(properties)) {

In my experience, it has expired at the end of that month. That is based on the fact that I can use it during that month, and that month is when my bank sends a new one.

The way i do it is:

   var obj = new Object();
   obj.name = "Raj";
   obj.age  = 32;
   obj.married = false;
   var jsonString= JSON.stringify(obj);

I guess this way can reduce chances for errors.

Here's a simple example:

Pattern pattern = Pattern.compile(regexPattern);
List<String> list = new ArrayList<String>();
Matcher m = pattern.matcher(input);
while (m.find()) {
    list.add(m.group());
}

(if you have more capturing groups, you can refer to them by their index as an argument of the group method. If you need an array, then use list.toArray())

The starting of react app is based on the main bundle download. React app only starts after the main bundle being downloaded in the browser. This is even true in case of lazy loading architecture. But the fact is we cannot exactly state the name of any bundles. Because webpack will add a hash value at the end of each bundle at the time when you run 'npm run build' command. Of course we can avoid that by changing hash settings, but it will seriously affect the cache data problem in the Browser. Browsers might not take the new version because of the same bundle name. . we need a webpack + js + CSS approach to handle this situation.

In your production webpack configuration change the HtmlWebpackPlugin option to below

 new HtmlWebpackPlugin({
          inject: false,
...

You may need to use 'eject' command to get the configuration file. latest webpack might have the option to configure the HtmlWebpackPlugin without ejecting project.

Compare outer and inner height/widths to get the total margin and padding:

var that = $("#myId");
alert(that.outerHeight(true) - that.innerHeight());

This is the easiest way:

import csv
with open('testfile.csv', newline='') as csvfile:
    data = list(csv.reader(csvfile))

Now each entry in data is a record, represented as an array. So you have a 2D array. It saved me so much time.

Try this

declare @v varchar(20)
set @v = 'Number'
select case when isnumeric(@v) = 1 then @v
else @v end

and

declare @v varchar(20)
set @v = '7082.7758172'
select case when isnumeric(@v) = 1 then @v
else convert(numeric(18,0),@v) end

I had the same problem and here is how it worked for me :

1) Open XAMPP control panel.

2)On the right top corner go to config > Service and Port setting and change the port (I did 81 from 80).

3)Open config in Apache just right(next) to Apache admin Option and click on that and select first one (httpd.conf) it will open in the notepad.

4) There you find port listen 80 and replace it with 81 in all place and save the file.

5) Now restart Apache and MYSql

6) Now type following in Browser : http://localhost:81/phpmyadmin/

I hope this works.

The most upvoted answer from @Kelly is no longer valid as @wescpy says. However after 2020-03-03 it will not work at all since the library used uses Google Sheets v3 API.

The Google Sheets v3 API will be shut down on March 3, 2020

As of PowerShell 2, simple:

$recipients = $addresses -split "; "

Note that the right hand side is actually a case-insensitive regular expression, not a simple match. Use csplit to force case-sensitivity. See about_Split for more details.

I played around with it a bit more and it seems like this is a side-effect of setting the tableView's tableHeaderView = nil.

Because my tableView has a dynamically appearing tableHeaderView, when I need to hide the tableHeaderView, instead of doing self.tableView.tableHeaderView = nil;, I do:

self.tableView.tableHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, self.tableView.bounds.size.width, 0.01f)];

I like this solution better than setting a somewhat arbitrary contentInset.top because I use the contentInset.top dynamically as well. Having to remember to remove an extra 35px whenever I recalculate contentInset.top is tedious.

I would like to share how I solved mine using Javascript function that is called on page load. This solution positions the footer at the bottom of the screen when the height of the page content is less than the height of the screen.

For production environments you should use Forever.js

It's so util for start and stop node process, you can list apps running too.

https://github.com/foreverjs/forever

You can redirect with multiple ways:

like

window.location.href = 'redirect_url';

another way Angular document:

import document from angular and the document must be inject as well as bellow otherwise you will get error

import { DOCUMENT  } from '@angular/common';
export class AppComponent {
     constructor(
       @Inject(DOCUMENT) private document: Document
    ) {}
   this.document.location.href = 'redirect_url';
}

Sure python-dev or libpython-all-dev are the first thing to (apt )install, but if that doesn't help as was my case, I advice you to install the foreign Function Interface packages by sudo apt-get install libffi-dev and sudo pip install cffi.

This should help out especially if you see the error as/from c/_cffi_backend.c:2:20: fatal error: Python.h: No such file or directory.

A string in C# is always UTF-16, there is no way to "convert" it. The encoding is irrelevant as long as you manipulate the string in memory, it only matters if you write the string to a stream (file, memory stream, network stream...).

If you want to write the string to a XML file, just specify the encoding when you create the XmlWriter

Your css will only work in IE browser. And the css suggessted by hayk.mart will olny work in webkit browsers. And by using different css hacks you can't style your browsers scroll bars with a same result.

So, it is better to use a jQuery/Javascript plugin to achieve a cross browser solution with a same result.

Solution:

By Using jScrollPane a jQuery plugin, you can achieve a cross browser solution

See This Demo

It should be:

Class.forName(String classname)

I will say no.

But the only proof that I have is personal experience and the fact that documentation on line continuation doesn't have anything else in it.

I know this is a long way from the year 2013 of the question, but this symptom can show up if you don't have lazy loading enabled when migrating an ASP.NET 5 app to ASP.NET Core, and then trying to upgrade to Entity Framework Core 2.x (from EF 6). Entity Framework Core has moved lazy loading proxy support to a separate package, so you have to install it.

This is particularly true if all you have loaded is an Entity Framework Core Sql Server package (which turns on Entity Framework just fine).

After installing the proxies package, then, as the docs say, invoke .UseLazyLoadingProxies() on the DbContext options builder (in your Startup DI setup section, or wherever you configure your DbContext), and the navigational property that was throwing the above exception will stop throwing it, and will work as Entity Framework 6 used to.

<a href="mailto:[email protected]?subject=Suggestions&body=name:%0D%0Aemail:">test</a>?
                                                                  ^^^^^^

You have to define a PersistentVolume providing disc space to be consumed by the PersistentVolumeClaim.

When using storageClass Kubernetes is going to enable "Dynamic Volume Provisioning" which is not working with the local file system.

To solve your issue:

• Provide a PersistentVolume fulfilling the constraints of the claim (a size >= 100Mi)
• Remove the storageClass-line from the PersistentVolumeClaim
• Remove the StorageClass from your cluster

How do these pieces play together?

At creation of the deployment state-description it is usually known which kind (amount, speed, ...) of storage that application will need.
To make a deployment versatile you'd like to avoid a hard dependency on storage. Kubernetes' volume-abstraction allows you to provide and consume storage in a standardized way.

The PersistentVolumeClaim is used to provide a storage-constraint alongside the deployment of an application.

The PersistentVolume offers cluster-wide volume-instances ready to be consumed ("bound"). One PersistentVolume will be bound to one claim. But since multiple instances of that claim may be run on multiple nodes, that volume may be accessed by multiple nodes.

A PersistentVolume without StorageClass is considered to be static.

"Dynamic Volume Provisioning" alongside with a StorageClass allows the cluster to provision PersistentVolumes on demand. In order to make that work, the given storage provider must support provisioning - this allows the cluster to request the provisioning of a "new" PersistentVolume when an unsatisfied PersistentVolumeClaim pops up.

Example PersistentVolume

In order to find how to specify things you're best advised to take a look at the API for your Kubernetes version, so the following example is build from the API-Reference of K8S 1.17:

apiVersion: v1
kind: PersistentVolume
metadata:
  name: ckan-pv-home
  labels:
    type: local
spec:
  capacity:
    storage: 100Mi
  hostPath:
    path: "/mnt/data/ckan"

The PersistentVolumeSpec allows us to define multiple attributes. I chose a hostPath volume which maps a local directory as content for the volume. The capacity allows the resource scheduler to recognize this volume as applicable in terms of resource needs.

C++11 has another (imperfect) option:

std::array<int, 100> a;
a.fill(-1);

In the code given in the question, I think that reading the ExitCode property of the initiation variable should work.

$process = Start-Process -FilePath ping -ArgumentList localhost -NoNewWindow -PassThru -Wait
$process.ExitCode

Note that (as in your example) you need to add the -PassThru and -Wait parameters (this caught me out for a while).

EDIT: Maybe your class for sending emails has an option for HTML emails and then you can use <br />

1) Double-quotes

$output = "Good news! The item# $item_number  on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n";

If you use double-quotes then \n will work (there will be no newline in browser but see the source code in your browser - the \n characters will be replaced for newlines)

2) Single quotes doesn't have the effect as the double-quotes above:

$output = 'Good news! The item# $item_number  on which you placed a bid of \$ $bid_price is now available for purchase at your bid price.\nThe seller, $bid_user is making this offer.\n\nItem Title : $title\n\nAll the best,\n $bid_user\n$email\n';

all characters will be printed as is (even variables!)

3) Line breaks in HTML

$html_output = "Good news! The item# $item_number  on which you placed a bid of <br />$ $bid_price is now available for purchase at your bid price.<br />The seller, $bid_user is making this offer.<br /><br />Item Title : $title<br /><br />All the best,<br /> $bid_user<br />$email<br />";

• There will be line breaks in your browser and variables will be replaced with their content.

private static String readAll(Reader rd) throws IOException {
    StringBuilder sb = new StringBuilder();
    int cp;
    while ((cp = rd.read()) != -1) {
      sb.append((char) cp);
    }
    return sb.toString();
  }

 String jsonText = readAll(inputofyourjsonstream);
 JSONObject json = new JSONObject(jsonText);
 JSONArray arr = json.getJSONArray("sources");

Your arr would looks like: [ { "id":1001, "name":"jhon" }, { "id":1002, "name":"jhon" } ] You can use:

arr.getJSONObject(index)

to get the objects inside of the array.

If you are using HTML5 date

use this code

HTML

<input type="date" name="bday" id="start_date"/>

Java Script

document.getElementById('start_date').value = Date();

How about:

from xx in table
where stringarray.Contains(xx.uid.ToString())
select xx

try $conn = mysql_connect("localhost", "root") or $conn = mysql_connect("localhost", "root", "")

There are MANY reasons to use brace initialization, but you should be aware that the initializer_list<> constructor is preferred to the other constructors, the exception being the default-constructor. This leads to problems with constructors and templates where the type T constructor can be either an initializer list or a plain old ctor.

struct Foo {
    Foo() {}

    Foo(std::initializer_list<Foo>) {
        std::cout << "initializer list" << std::endl;
    }

    Foo(const Foo&) {
        std::cout << "copy ctor" << std::endl;
    }
};

int main() {
    Foo a;
    Foo b(a); // copy ctor
    Foo c{a}; // copy ctor (init. list element) + initializer list!!!
}

Assuming you don't encounter such classes there is little reason not to use the intializer list.

In my situation, I needed to retain unique keys with the array values, so I just used a second array:

$arr1 = array("alpha"=>"bravo","charlie"=>"delta","echo"=>"foxtrot");
unset($arr1);

$arr2 = array();
foreach($arr1 as $key=>$value) $arr2[$key] = $value;
$arr1 = $arr2
unset($arr2);

The code by @Android is very good but has few issues, namely:

1. Populating to ListView code needs to be moved to onReceive of BroadCastReceiver where only the result will be available. In the case result is obtained at 2nd attempt.
2. BroadCastReceiver needs to be unregistered after the results are obtained.
3. size = size -1 seems unnecessary.

Find below the modified code of @Android as a working example:

Warning, Chrome (and other browsers) will complain that multiple ACAO headers are set if you follow some of the other answers.

The error will be something like XMLHttpRequest cannot load ____. The 'Access-Control-Allow-Origin' header contains multiple values '____, ____, ____', but only one is allowed. Origin '____' is therefore not allowed access.

Try this:

$http_origin = $_SERVER['HTTP_ORIGIN'];

$allowed_domains = array(
  'http://domain1.com',
  'http://domain2.com',
);

if (in_array($http_origin, $allowed_domains))

I would also recommend to use Notepad++ with json-view extension. You get the extension here: https://sourceforge.net/projects/nppjsonviewer/ Install and restart Notepad++. Then open json-file in Notepad and go to "extensions -> Json-Viewer - > Format JSON. Then you habe the hierarchical view of json.

You can also use one of the online-viewers (http://jsonviewer.stack.hu/ , https://jsoneditoronline.org/) which look nice, but I wouldn't recommend this if your data are sensitive in terms of privacy.

subscript

extension Array where Element : Equatable {
  public subscript(safe bounds: Range<Int>) -> ArraySlice<Element> {
    if bounds.lowerBound > count { return [] }
    let lower = Swift.max(0, bounds.lowerBound)
    let upper = Swift.max(0, Swift.min(count, bounds.upperBound))
    return self[lower..<upper]
  }
  
  public subscript(safe lower: Int?, _ upper: Int?) -> ArraySlice<Element> {
    let lower = lower ?? 0
    let upper = upper ?? count
    if lower > upper { return [] }
    return self[safe: lower..<upper]
  }
}

returns a copy of this range clamped to the given limiting range.

var arr = [1, 2, 3]
    
arr[safe: 0..<1]    // returns [1]  assert(arr[safe: 0..<1] == [1])
arr[safe: 2..<100]  // returns [3]  assert(arr[safe: 2..<100] == [3])
arr[safe: -100..<0] // returns []   assert(arr[safe: -100..<0] == [])

arr[safe: 0, 1]     // returns [1]  assert(arr[safe: 0, 1] == [1])
arr[safe: 2, 100]   // returns [3]  assert(arr[safe: 2, 100] == [3])
arr[safe: -100, 0]  // returns []   assert(arr[safe: -100, 0] == [])

In JSP, you can use this in page directive:

<%@ page language="java" contentType="application/json; charset=UTF-8"
    pageEncoding="UTF-8"%>

The correct MIME media type for JSON is application/json. JSP will use it for sending a response to the client.

In the following example you have an PHP array, then firstly create a JavaScript array by a PHP array:

<script type="javascript">
    day = new Array(<?php echo implode(',', $day); ?>);
    week = new Array(<?php echo implode(',',$week); ?>);
    month = new Array(<?php echo implode(',',$month); ?>);

    <!--  Then pass it to the JavaScript function:   -->

    drawChart(<?php echo count($day); ?>, day, week, month);
</script>

I would recommend reading in the line into a string, then splitting it based on the spaces. For this, you can use the getline(...) function. The trick is having a dynamic sized data structure to hold the strings once it's split. Probably the easiest to use would be a vector.

#include <string>
#include <vector>
...
  string rawInput;
  vector<String> numbers;
  while( getline( cin, rawInput, ' ' ) )
  {
    numbers.push_back(rawInput);
  }

So say the input looks like this:

Enter a number, or numbers separated by a space, between 1 and 1000.
10 5 20 1 200 7

You will now have a vector, numbers, that contains the elements: {"10","5","20","1","200","7"}.

Note that these are still strings, so not useful in arithmetic. To convert them to integers, we use a combination of the STL function, atoi(...), and because atoi requires a c-string instead of a c++ style string, we use the string class' c_str() member function.

while(!numbers.empty())
{
  string temp = numbers.pop_back();//removes the last element from the string
  num = atoi( temp.c_str() ); //re-used your 'num' variable from your code

  ...//do stuff
}

Now there's some problems with this code. Yes, it runs, but it is kind of clunky, and it puts the numbers out in reverse order. Lets re-write it so that it is a little more compact:

#include <string>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  num = atoi( rawInput.c_str() );
  ...//do your stuff
}

There's still lots of room for improvement with error handling (right now if you enter a non-number the program will crash), and there's infinitely more ways to actually handle the input to get it in a usable number form (the joys of programming!), but that should give you a comprehensive start. :)

Note: I had the reference pages as links, but I cannot post more than two since I have less than 15 posts :/

Edit: I was a little bit wrong about the atoi behavior; I confused it with Java's string->Integer conversions which throw a Not-A-Number exception when given a string that isn't a number, and then crashes the program if the exception isn't handled. atoi(), on the other hand, returns 0, which is not as helpful because what if 0 is the number they entered? Let's make use of the isdigit(...) function. An important thing to note here is that c++ style strings can be accessed like an array, meaning rawInput[0] is the first character in the string all the way up to rawInput[length - 1].

#include <string>
#include <ctype.h>
...
string rawInput;
cout << "Enter a number, or numbers separated by a space, between 1 and 1000." << endl;
while( getline( cin, rawInput, ' ') )
{
  bool isNum = true;
  for(int i = 0; i < rawInput.length() && isNum; ++i)
  {
    isNum = isdigit( rawInput[i]);
  }

  if(isNum)
  {
    num = atoi( rawInput.c_str() );
    ...//do your stuff
  }
  else
    cout << rawInput << " is not a number!" << endl;
}

The boolean (true/false or 1/0 respectively) is used as a flag for the for-loop, which steps through each character in the string and checks to see if it is a 0-9 digit. If any character in the string is not a digit, the loop will break during it's next execution when it gets to the condition "&& isNum" (assuming you've covered loops already). Then after the loop, isNum is used to determine whether to do your stuff, or to print the error message.

Yes, it is possible. Here is the solution

export interface Foo {

    test(): void;
}

export namespace Foo {

    export function statMethod(): void {
        console.log(2);
    }

}

This is a Python3 function for converting any text file into the one with UTF-8 encoding. (without using unnecessary packages)

def correctSubtitleEncoding(filename, newFilename, encoding_from, encoding_to='UTF-8'):
    with open(filename, 'r', encoding=encoding_from) as fr:
        with open(newFilename, 'w', encoding=encoding_to) as fw:
            for line in fr:
                fw.write(line[:-1]+'\r\n')

You can use it easily in a loop to convert a list of files.

This is the answer for the question.Reason for the cause is my LDAP string was wrong.

    try
    {
        string adServer = ConfigurationManager.AppSettings["Server"];
        string adDomain = ConfigurationManager.AppSettings["Domain"];
        string adUsername = ConfigurationManager.AppSettings["AdiminUsername"];
        string password = ConfigurationManager.AppSettings["Password"];
        string[] dc = adDomain.Split('.');
        string dcAdDomain = string.Empty;

        foreach (string item in dc)
        {
            if (dc[dc.Length - 1].Equals(item))
                dcAdDomain = dcAdDomain + "DC=" + item;
            else
                dcAdDomain = dcAdDomain + "DC=" + item + ",";
        }

        DirectoryEntry de = new DirectoryEntry("LDAP://" + adServer + "/CN=Users," + dcAdDomain, adUsername, password);

        DirectorySearcher ds = new DirectorySearcher(de);

        ds.SearchScope = SearchScope.Subtree;

        ds.Filter = "(&(objectClass=User)(sAMAccountName=" + username + "))";

        if (ds.FindOne() != null)
            return true;
    }
    catch (Exception ex)
    {
        ExLog(ex);
    }
    return false;

Make sure both your System and User paths are set correctly.

Some of the Exe files Dependents on Some services,

So you need find the respective service and stop first.

Use the hex code for a non-breaking space. Something like this:

There are 2 answers for this question Url & directory. Either way, the elegant way would be to define two constants for later use.

define (ROOT_URL, get_site_url() );
define (ROOT_DIR, get_theme_root() );

I found this on Microsoft Dev Center. It works correctly and ignores double-clicking in wrong places. As you see, the point is that an item gets selected before double-click event is triggered.

private void listView1_DoubleClick(object sender, EventArgs e)
{
    // user clicked an item of listview control
    if (listView1.SelectedItems.Count == 1)
    {
        //do what you need to do here            
    }

   // Do stuff..

I highly recommend reading the docs on the Intent.FLAG_ACTIVITY_CLEAR_TOP flag. Using it will not necessarily go back all the way to the first (main) activity. The flag will only remove all existing activities up to the activity class given in the Intent. This is explained well in the docs:

For example, consider a task consisting of the activities: A, B, C, D.
If D calls startActivity() with an Intent that resolves to the component of
activity B, then C and D will be finished and B receive the given Intent, 
resulting in the stack now being: A, B.

Note that the activity can set to be moved to the foreground (i.e., clearing all other activities on top of it), and then also being relaunched, or only get onNewIntent() method called.

It may be easier. Try to think like this:

• first catch a string between regular characters
• after that find "case"

:

// 'www.dev.yyy.com'
// 'xxx.foo.pl'

var url = "xxx.foo.pl";

switch (url.match(/\..*.\./)[0]){
   case ".dev.yyy." :
          console.log("xxx.dev.yyy.com");break;

   case ".some.":
          console.log("xxx.foo.pl");break;
} //end switch

Xcode provides a code snippet to do this. You just have to enter the delay value and the code you wish to run after the delay.

1. click on the + button at the top right of Xcode.
2. search for after
3. It will return only 1 search result, which is the desired snippet (see screenshot). Double click it and you're good to go.

You may try

document.getElementById('name').style.borderColor='#e52213';
document.getElementById('name').style.border='solid';

In either case, I'd expect file.getParent() (or file.getParentFile()) to give you what you want.

Additionally, if you want to find out whether the original File does exist and is a directory, then exists() and isDirectory() are what you're after.

In answer to your second question: Yes a HashMap can hold different types of objects. Whether that's a good idea or not depends on the problem you're trying to solve.

That said, your example won't work. The int value is not an Object. You have to use the Integer wrapper class to store an int value in a HashMap

I already said that I was new to exec() function. After doing some more digging, I came upon 2>&1 which needs to be added at the end of command in exec().

Thanks @mattosmat for pointing it out in the comments too. I did not try this at once because you said it is a Linux command, I am on Windows.

So, what I have discovered, the command is actually executing in the back-end. That is why I could not see it actually running, which I was expecting to happen.

For all of you, who had similar problem, my advise is to use that command. It will point out all the errors and also tell you info/details about execution.

exec('some_command 2>&1', $output);
print_r($output);  // to see the response to your command

Thanks for all the help guys, I appreciate it ;)

I see a lot of tricks and such being used. Now I'm not against beautiful tricks but personally I like to simply call the methods that are meant to do the work, so I've created yet another answer.

Note that if performance is any issue, use Jon Skeet's answer instead. This one is a bit more generalized and therefore slightly more readable in my opinion (and of course, reusable for strings and patterns).

public static int countOccurances(char c, String input) {
    return countOccurancesOfPattern(Pattern.quote(Character.toString(c)), input);
}

public static int countOccurances(String s, String input) {
    return countOccurancesOfPattern(Pattern.quote(s), input);
}

public static int countOccurancesOfPattern(String pattern, String input) {
    Matcher m = Pattern.compile(pattern).matcher(input);
    int count = 0;
    while (m.find()) {
        count++;
    }
    return count;
}

You need text() or html() for label not val() The function should not be called for label instead it is used to get values of input like text or checkbox etc.

Change

value = $("#telefon").val(); 

To

value = $("#telefon").text();

I know how this can be done using fgets and strtol, I would like to know how this can be done using scanf() (if possible).

As the other answers say, scanf isn't really suitable for this, fgets and strtol is an alternative (though fgets has the drawback that it's hard to detect a 0-byte in the input and impossible to tell what has been input after a 0-byte, if any).

For sake of completeness (and assuming valid input is an integer followed by a newline):

while(scanf("%d%1[\n]", &n, (char [2]){ 0 }) < 2)

Alternatively, use %n before and after %*1[\n] with assignment-suppression. Note, however (from the Debian manpage):

This is not a conversion, although it can be suppressed with the * assignment-suppression character. The C standard says: "Execution of a %n directive does not increment the assignment count returned at the completion of execution" but the Corrigendum seems to contradict this. Probably it is wise not to make any assumptions on the effect of %n conversions on the return value.

The following adds one line after SearchPattern.

sed -i '/SearchPattern/aNew Text' SomeFile.txt

It inserts New Text one line below each line that contains SearchPattern.

To add two lines, you can use a \ and enter a newline while typing New Text.

POSIX sed requires a \ and a newline after the a sed function. [1] Specifying the text to append without the newline is a GNU sed extension (as documented in the sed info page), so its usage is not as portable.

We had the same problem on a CentOS7 machine. Disabling the VERIFYHOST VERIFYPEER did not solve the problem, we did not have the cURL error anymore but the response still was invalid. Doing a wget to the same link as the cURL was doing also resulted in a certificate error.

-> Our solution also was to reboot the VPS, this solved it and we were able to complete the request again.

For us this seemed to be a memory corruption problem. Rebooting the VPS reloaded the libary in the memory again and now it works. So if the above solution from @clover does not work try to reboot your machine.

This question is old, but is missing some benchmarks. I benchmarked JOIN against its 2 competitors:

• N+1 queries
• 2 queries, the second one using a WHERE IN(...) or equivalent

The result is clear: on MySQL, JOIN is much faster. N+1 queries can drop the performance of an application drastically:

That is, unless you select a lot of records that point to a very small number of distinct, foreign records. Here is a benchmark for the extreme case:

This is very unlikely to happen in a typical application, unless you're joining a -to-many relationship, in which case the foreign key is on the other table, and you're duplicating the main table data many times.

Takeaway:

• For *-to-one relationships, always use JOIN
• For *-to-many relationships, a second query might be faster

See my article on Medium for more information.

Try below code :

Assign the path of the folder to variable FolderPath before running the below code.

Sub sample()

    Dim FolderPath As String, path As String, count As Integer
    FolderPath = "C:\Documents and Settings\Santosh\Desktop"

    path = FolderPath & "\*.xls"

    Filename = Dir(path)

    Do While Filename <> ""
       count = count + 1
        Filename = Dir()
    Loop

    Range("Q8").Value = count
    'MsgBox count & " : files found in folder"
End Sub

Tables and table cells don't use the min-height property, setting their height will be the min-height as tables will expand if the content stretches them.

Windows uses .cer extension for an X.509 certificate. These can be in "binary" (ASN.1 DER), or it can be encoded with Base-64 and have a header and footer applied (PEM); Windows will recognize either. To verify the integrity of a certificate, you have to check its signature using the issuer's public key... which is, in turn, another certificate.

Windows uses .pfx for a PKCS #12 file. This file can contain a variety of cryptographic information, including certificates, certificate chains, root authority certificates, and private keys. Its contents can be cryptographically protected (with passwords) to keep private keys private and preserve the integrity of root certificates.

Windows uses .pvk for a private key file. I'm not sure what standard (if any) Windows follows for these. Hopefully they are PKCS #8 encoded keys. Emmanuel Bourg reports that these are a proprietary format. Some documentation is available.

You should never disclose your private key. These are contained in .pfx and .pvk files.

Generally, you only exchange your certificate (.cer) and the certificates of any intermediate issuers (i.e., the certificates of all of your CAs, except the root CA) with other parties.

ENABLE is what you are looking for

USAGE: type this command once and then you are good to go. Your service will start automaticaly at boot up

 sudo systemctl enable postgresql

DISABLE exists as well ofc

This is still an issue in VS Community 2015 and 2017 when building either console or windows apps. If the project is created with precompiled headers, the precompiled headers are apparently loaded before any of the #includes, so even if the #define _USE_MATH_DEFINES is the first line, it won't compile. #including math.h instead of cmath does not make a difference.

The only solutions I can find are either to start from an empty project (for simple console or embedded system apps) or to add /Y- to the command line arguments, which turns off the loading of precompiled headers.

For information on disabling precompiled headers, see for example https://msdn.microsoft.com/en-us/library/1hy7a92h.aspx

It would be nice if MS would change/fix this. I teach introductory programming courses at a large university, and explaining this to newbies never sinks in until they've made the mistake and struggled with it for an afternoon or so.

Step 1 : HTML Code-sample

<div ng-app ng-controller="ExampleCtrl">
    <div ng-show="countDown_text > 0">Your password is expired in 180 Seconds.</div>
    <div ng-show="countDown_text > 0">Seconds left {{countDown_text}}</div>
    <div ng-show="countDown_text == 0">Your password is expired!.</div>
</div>

      return; // quit
    } else {
      $scope.countDown_text = countDown; // update scope
      countDown--; // -1
      $timeout(countDowner, 1000); // loop it again
    }

From Dockerfile reference:

• The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag.

• The ENV instruction sets the environment variable <key> to the value <value>.
  The environment variables set using ENV will persist when a container is run from the resulting image.

So if you need build-time customization, ARG is your best choice.
If you need run-time customization (to run the same image with different settings), ENV is well-suited.

If I want to add let's say 20 (a random number) of extensions or any other feature that can be enable|disable

Given the number of combinations involved, using ENV to set those features at runtime is best here.

But you can combine both by:

• building an image with a specific ARG
• using that ARG as an ENV

That is, with a Dockerfile including:

ARG var
ENV var=${var}

You can then either build an image with a specific var value at build-time (docker build --build-arg var=xxx), or run a container with a specific runtime value (docker run -e var=yyy)

There is a php library (pdfparser) that does exactly what you want.

project website

http://www.pdfparser.org/

github

https://github.com/smalot/pdfparser

Demo page/api

http://www.pdfparser.org/demo

After including pdfparser in your project you can get all text from mypdf.pdf like so:

<?php
$parser = new \installpath\PdfParser\Parser();
$pdf    = $parser->parseFile('mypdf.pdf');  
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf

?>

Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).

In general, x and y must satisfy (x - center_x)^2 + (y - center_y)^2 < radius^2.

Please note that points that satisfy the above equation with < replaced by == are considered the points on the circle, and the points that satisfy the above equation with < replaced by > are considered the outside the circle.

Does your upload die at the very end? 99% before crashing? Client body and buffers are key because nginx must buffer incoming data. The body configs (data of the request body) specify how nginx handles the bulk flow of binary data from multi-part-form clients into your app's logic.

The clean setting frees up memory and consumption limits by instructing nginx to store incoming buffer in a file and then clean this file later from disk by deleting it.

Set body_in_file_only to clean and adjust buffers for the client_max_body_size. The original question's config already had sendfile on, increase timeouts too. I use the settings below to fix this, appropriate across your local config, server, & http contexts.

client_body_in_file_only clean;
client_body_buffer_size 32K;

client_max_body_size 300M;

sendfile on;
send_timeout 300s;

2015-03-30: Edited - Missing information has been added

To retrieve the current directory you can use the dynamic %cd% variable that holds the current active directory

set "curpath=%cd%"

This generates a value with a ending backslash for the root directory, and without a backslash for the rest of directories. You can force and ending backslash for any directory with

for %%a in ("%cd%\") do set "curpath=%%~fa"

Or you can use another dynamic variable: %__CD__% that will return the current active directory with an ending backslash.

Also, remember the %cd% variable can have a value directly assigned. In this case, the value returned will not be the current directory, but the assigned value. You can prevent this with a reference to the current directory

for %%a in (".\") do set "curpath=%%~fa"

Up to windows XP, the %__CD__% variable has the same behaviour. It can be overwritten by the user, but at least from windows 7 (i can't test it on Vista), any change to the %__CD__% is allowed but when the variable is read, the changed value is ignored and the correct current active directory is retrieved (note: the changed value is still visible using the set command).

BUT all the previous codes will return the current active directory, not the directory where the batch file is stored.

set "curpath=%~dp0"

It will return the directory where the batch file is stored, with an ending backslash.

BUT this will fail if in the batch file the shift command has been used

shift
echo %~dp0

As the arguments to the batch file has been shifted, the %0 reference to the current batch file is lost.

To prevent this, you can retrieve the reference to the batch file before any shifting, or change the syntax to shift /1 to ensure the shift operation will start at the first argument, not affecting the reference to the batch file. If you can not use any of this options, you can retrieve the reference to the current batch file in a call to a subroutine

@echo off
    setlocal enableextensions

    rem Destroy batch file reference
    shift
    echo batch folder is "%~dp0"

    rem Call the subroutine to get the batch folder 
    call :getBatchFolder batchFolder
    echo batch folder is "%batchFolder%"

    exit /b

:getBatchFolder returnVar
    set "%~1=%~dp0" & exit /b

This approach can also be necessary if when invoked the batch file name is quoted and a full reference is not used (read here).

Since the class Number is not final, here is an idea, that I don't find yet in the other posts. Namely to subclass the class Number.

This would somehow deliver an object that can be treated as infinity for Integer, Long, Double, Float, BigInteger and BigDecimal.

Since there are only two values, we could use the singleton pattern:

public final class Infinity extends Number {
    public final static Infinity POSITIVE = new Infinity(false);
    public final static Infinity NEGATIVE = new Infinity(true);
    private boolean negative;
    private Infinity(boolean n) {
        negative = n;
    }
}

Somehow I think the remaining methods intValue(), longValue() etc.. should then be overriden to throw an exceptions. So that the infinity value cannot be used without further precautions.

in Core Php to hide warning message set error_reporting(0) at top of common include file or individual file.

In Wordpress hide Warnings and Notices add following code in wp-config.php file

ini_set('log_errors','On');
ini_set('display_errors','Off');
ini_set('error_reporting', E_ALL );
define('WP_DEBUG', false);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);

A method of an object that needs to use a "sleep" method such as the following:

function SomeObject() {
    this.SomeProperty = "xxx";
    return this;
}
SomeObject.prototype.SomeMethod = function () {
    this.DoSomething1(arg1);
    sleep(500);
    this.DoSomething2(arg1);
}

Can almost be translated to:

function SomeObject() {
    this.SomeProperty = "xxx";
    return this;
}
SomeObject.prototype.SomeMethod = function (arg1) {
    var self = this;
    self.DoSomething1(arg1);
    setTimeout(function () {
        self.DoSomething2(arg1);
    }, 500);
}

The difference is that the operation of "SomeMethod" returns before the operation "DoSomething2" is executed. The caller of "SomeMethod" cannot depend on this. Since the "Sleep" method does not exists, I use the later method and design my code accordingly.

I hope this helps.

Install pip

Download get-pip. Remember to save it as "get-pip.py"

Now go to the download folder. Right click on get-pip.py then open with python.exe.

You can add system variable by

(by doing this you can use pip and easy_install without specifying path)

1 Clicking on Properties of My Computer

2 Then chose Advanced System Settings

3 Click on Advanced Tab

4 Click on Environment Variables

5 From System Variables >>> select variable path.

6 Click edit then add the following lines at the end of it

 ;c:\Python27;c:\Python27\Scripts

(please dont copy this, just go to your python directory and copy the paths similar to this)

NB:- you have to do this once only.

Install beautifulsoup4

Open cmd and type

pip install beautifulsoup4

cd "`dirname $(readlink -f ${0})`"

You need to import time and then use time.time() method to know current time.

import time

start_time=time.time() #taking current time as starting time

#here your code

elapsed_time=time.time()-start_time #again taking current time - starting time 

No need to pass anything in. The function used for addEventListener will automatically have this bound to the current element. Simply use this in your function:

productLineSelect.addEventListener('change', getSelection, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

Here's the fiddle: http://jsfiddle.net/dJ4Wm/

If you want to pass arbitrary data to the function, wrap it in your own anonymous function call:

productLineSelect.addEventListener('change', function() {
    foo('bar');
}, false);

function foo(message) {
    alert(message);
}

Here's the fiddle: http://jsfiddle.net/t4Gun/

If you want to set the value of this manually, you can use the call method to call the function:

var self = this;
productLineSelect.addEventListener('change', function() {
    getSelection.call(self);
    // This'll set the `this` value inside of `getSelection` to `self`
}, false);

function getSelection() {
    var value = this.options[this.selectedIndex].value;
    alert(value);
}

These are behavior patterns I have noticed while trying to understand Jackson serialization.

1) Assume there is an object Classroom and a class Student. I've made everything public and final for ease.

public class Classroom {
    public final double double1 = 1234.5678;
    public final Double Double1 = 91011.1213;
    public final Student student1 = new Student();
}

public class Student {
    public final double double2 = 1920.2122;
    public final Double Double2 = 2324.2526;
}

2) Assume that these are the serializers we use for serializing the objects into JSON. The writeObjectField uses the object's own serializer if it is registered with the object mapper; if not, then it serializes it as a POJO. The writeNumberField exclusively only accepts primitives as arguments.

public class ClassroomSerializer extends StdSerializer<Classroom> {
    public ClassroomSerializer(Class<Classroom> t) {
        super(t);
    }

    @Override
    public void serialize(Classroom value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonGenerationException {
        jgen.writeStartObject();
        jgen.writeObjectField("double1-Object", value.double1);
        jgen.writeNumberField("double1-Number", value.double1);
        jgen.writeObjectField("Double1-Object", value.Double1);
        jgen.writeNumberField("Double1-Number", value.Double1);
        jgen.writeObjectField("student1", value.student1);
        jgen.writeEndObject();
    }
}

public class StudentSerializer extends StdSerializer<Student> {
    public StudentSerializer(Class<Student> t) {
        super(t);
    }

    @Override
    public void serialize(Student value, JsonGenerator jgen, SerializerProvider provider) throws IOException, JsonGenerationException {
        jgen.writeStartObject();
        jgen.writeObjectField("double2-Object", value.double2);
        jgen.writeNumberField("double2-Number", value.double2);
        jgen.writeObjectField("Double2-Object", value.Double2);
        jgen.writeNumberField("Double2-Number", value.Double2);
        jgen.writeEndObject();
    }
}

3) Register only a DoubleSerializer with DecimalFormat output pattern ###,##0.000, in SimpleModule and the output is:

{
  "double1" : 1234.5678,
  "Double1" : {
    "value" : "91,011.121"
  },
  "student1" : {
    "double2" : 1920.2122,
    "Double2" : {
      "value" : "2,324.253"
    }
  }
}

You can see that the POJO serialization differentiates between double and Double, using the DoubleSerialzer for Doubles and using a regular String format for doubles.

4) Register DoubleSerializer and ClassroomSerializer, without the StudentSerializer. We expect that the output is such that if we write a double as an object, it behaves like a Double, and if we write a Double as a number, it behaves like a double. The Student instance variable should be written as a POJO and follow the pattern above since it does not register.

{
  "double1-Object" : {
    "value" : "1,234.568"
  },
  "double1-Number" : 1234.5678,
  "Double1-Object" : {
    "value" : "91,011.121"
  },
  "Double1-Number" : 91011.1213,
  "student1" : {
    "double2" : 1920.2122,
    "Double2" : {
      "value" : "2,324.253"
    }
  }
}

5) Register all serializers. The output is:

{
  "double1-Object" : {
    "value" : "1,234.568"
  },
  "double1-Number" : 1234.5678,
  "Double1-Object" : {
    "value" : "91,011.121"
  },
  "Double1-Number" : 91011.1213,
  "student1" : {
    "double2-Object" : {
      "value" : "1,920.212"
    },
    "double2-Number" : 1920.2122,
    "Double2-Object" : {
      "value" : "2,324.253"
    },
    "Double2-Number" : 2324.2526
  }
}

exactly as expected.

Another important note: If you have multiple serializers for the same class registered with the same Module, then the Module will select the serializer for that class that is most recently added to the list. This should not be used - it's confusing and I am not sure how consistent this is

Moral: if you want to customize serialization of primitives in your object, you must write your own serializer for the object. You cannot rely on the POJO Jackson serialization.

Missing a semicolon

if [ -a myApp ];
then
  rm myApp
fi

However, I assume you are checking for existence before deletion to prevent an error message. If so, you can just use rm -f myApp which "forces" delete, i.e. doesn't error out if the file didn't exist.

The linefeed character \n is not the line separator in certain operating systems (such as windows, where it's "\r\n") - my suggestion is that you use \r\n instead, then it'll both see the line-break with only \n and \r\n, I've never had any problems using it.

Also, you should look into using a StringBuilder instead of concatenating the String in the while-loop at BookCatalog.toString(), it is a lot more effective. For instance:

public String toString() {
        BookNode current = front;
        StringBuilder sb = new StringBuilder();
        while (current!=null){
            sb.append(current.getData().toString()+"\r\n ");
            current = current.getNext();
        }
        return sb.toString();
}

Just to extend the pratical scope of the question and as an appendix to the given answers: Sometimes one might find it necessary to specify the selectors a little bit more.

By defining the the full span as display:inline-block you might have a hard time displaying images.

Therefore I prefer to define a span like so:

span {
  display:block;
  width:150px;
  word-wrap:break-word;      
}
p span, a span,
h1 span, h2 span, h3 span, h4 span, h5 span {
  display:inline-block;
}
img{
  display:block;
}

$arr1 = array(
   "0" => array("fid" => 1, "tid" => 1, "name" => "Melon"),
   "1" => array("fid" => 1, "tid" => 4, "name" => "Tansuozhe"),
   "2" => array("fid" => 1, "tid" => 6, "name" => "Chao"),
   "3" => array("fid" => 1, "tid" => 7, "name" => "Xi"),
   "4" => array("fid" => 2, "tid" => 9, "name" => "Xigua")
);

if you want to convert this array as following:

$arr2 = array(
   "0" => array(
          "0" => array("fid" => 1, "tid" => 1, "name" => "Melon"),
          "1" => array("fid" => 1, "tid" => 4, "name" => "Tansuozhe"),
          "2" => array("fid" => 1, "tid" => 6, "name" => "Chao"),
          "3" => array("fid" => 1, "tid" => 7, "name" => "Xi")
    ),

    "1" => array(
          "0" =>array("fid" => 2, "tid" => 9, "name" => "Xigua")
     )
);

so, my answer will be like this:

$outer_array = array();
$unique_array = array();
foreach($arr1 as $key => $value)
{
    $inner_array = array();

    $fid_value = $value['fid'];
    if(!in_array($value['fid'], $unique_array))
    {
            array_push($unique_array, $fid_value);
            unset($value['fid']);
            array_push($inner_array, $value);
            $outer_array[$fid_value] = $inner_array;


    }else{
            unset($value['fid']);
            array_push($outer_array[$fid_value], $value);

    }
}

 if ( getActivity().getPackageManager().hasSystemFeature(PackageManager.FEATURE_CAMERA_FLASH)) {

One option is to use lapply and class. For example:

> foo <- data.frame(c("a", "b"), c(1, 2))
> names(foo) <- c("SomeFactor", "SomeNumeric")
> lapply(foo, class)
$SomeFactor
[1] "factor"

$SomeNumeric
[1] "numeric"

Another option is str:

> str(foo)
'data.frame':   2 obs. of  2 variables:
 $ SomeFactor : Factor w/ 2 levels "a","b": 1 2
 $ SomeNumeric: num  1 2

As others have pointed out, the $x are capture variables for regular expressions, allowing you to reference sections of a matched pattern.

Perl also supports named captures which might be easier for humans to remember in some cases.

Given input: 111 222

/(\d+)\s+(\d+)/

$1 is 111

$2 is 222

One could also say:

/(?<myvara>\d+)\s+(?<myvarb>\d+)/

$+{myvara} is 111

$+{myvarb} is 222

I suggest split (not saying that the other answers are invalid, this is just another way to do it):

def findreplace(char, string):
   return ''.join(string.split(char))

Splitting by a character removes all the characters and turns it into a list. Then we join the list with the join function. You can see the ipython console test below

In[112]: findreplace('i', 'it is icy')
Out[112]: 't s cy'

And the speed...

In[114]: timeit("findreplace('it is icy','i')", "from __main__ import findreplace")
Out[114]: 0.9927914671134204

Not as fast as replace or translate, but ok.

No you cannot. The only thing you can do is to insert content. Like so:

p:after {
    content: "yo";
}

After trying almost all the solutions listed above, what finally worked for me was to create a new virtual device using a "Google APIs" image instead of a "Google Play" image.

Reasons for this issues are:

1. Any one application may be running on this port like Skype.
2. Node may have crashed and port may not have been freed.
3. You may have tried to start server more than one. To solve this problem, one can maintain a boolean to check whether server have been started or not. It should be started only if boolean return false or undefined;

<?php 

    $username=urldecode($_POST['log_user']);

    $user="select * from tbl_registration where member_id= '".$username."' ";
    $rsuser = $obj->select($user);
    if(count($rsuser)>0)
    {
        //   (Status if 2 then its expire)    (1= use) ( 0 = not use)

        $cheknew="select name,ldate,offer_photo  from tbl_offer where status=1 ";
        $rscheknew = $obj->selectjson($cheknew);

        if(count($rscheknew)>0)
        {

             $nik=json_encode($rscheknew);
            echo "{\"status\" : \"200\" ,\"responce\" : \"201\", \"message\" : \"Get Record\",\"feed\":".str_replace("<p>","",$nik). "}";
        }
        else
        {
            $row2="No Record Found";
            $nik1=json_encode($row2);
            echo "{\"status\" : \"202\",  \"responce\" : \"604\",\"message\" : \"No Record Found \",\"feed\":".str_replace("<p>","",$nik1). "}";
        }
    }
    else
    {
        $row2="Invlid User";
        $nik1=json_encode($row2);
        echo "{\"status\" : \"404\", \"responce\" : \"602\",\"message\" : \"Invlid User \",\"feed\":".str_replace("<p>","",$nik1). "}";
    }

Cern's ROOT produces some pretty nice stuff, I use it to display Neural Network data a lot.

setInterval returns an ID which you then use to clear the interval.

var intervalId;
on.onclick = function() {
    if (intervalId) {
        clearInterval(intervalId);
    }
    intervalId = setInterval(fontChange, 500);
};

off.onclick = function() {
    clearInterval(intervalId);
}; 

Switch to the branch from which you created the pull request:

$ git checkout pull-request-branch

Overwrite the modified file(s) with the file in another branch, let's consider it's master:

git checkout origin/master -- src/main/java/HelloWorld.java

Commit and push it to the remote:

git commit -m "Removed a modified file from pull request"
git push origin pull-request-branch

There are two ways of storing a color with alpha. The first is exactly as you see it, with each component as-is. The second is to use pre-multiplied alpha, where the color values are multiplied by the alpha after converting it to the range 0.0-1.0; this is done to make compositing easier. Ordinarily you shouldn't notice or care which way is implemented by any particular engine, but there are corner cases where you might, for example if you tried to increase the opacity of the color. If you use rgba(0, 0, 0, 0) you are less likely to to see a difference between the two approaches.

Actually you are right: it runs another instance of make. A possible solution would be:

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : clean clearscr all

clearscr:
    clear

By calling make fresh you get first the clean target, then the clearscreen which runs clear and finally all which does the job.

EDIT Aug 4

What happens in the case of parallel builds with make’s -j option? There's a way of fixing the order. From the make manual, section 4.2:

Occasionally, however, you have a situation where you want to impose a specific ordering on the rules to be invoked without forcing the target to be updated if one of those rules is executed. In that case, you want to define order-only prerequisites. Order-only prerequisites can be specified by placing a pipe symbol (|) in the prerequisites list: any prerequisites to the left of the pipe symbol are normal; any prerequisites to the right are order-only: targets : normal-prerequisites | order-only-prerequisites

The normal prerequisites section may of course be empty. Also, you may still declare multiple lines of prerequisites for the same target: they are appended appropriately. Note that if you declare the same file to be both a normal and an order-only prerequisite, the normal prerequisite takes precedence (since they are a strict superset of the behavior of an order-only prerequisite).

Hence the makefile becomes

.PHONY : clearscr fresh clean all

all :
    compile executable

clean :
    rm -f *.o $(EXEC)

fresh : | clean clearscr all

clearscr:
    clear

EDIT Dec 5

It is not a big deal to run more than one makefile instance since each command inside the task will be a sub-shell anyways. But you can have reusable methods using the call function.

log_success = (echo "\x1B[32m>> $1\x1B[39m")
log_error = (>&2 echo "\x1B[31m>> $1\x1B[39m" && exit 1)

install:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  command1  # this line will be a subshell
  command2  # this line will be another subshell
  @command3  # Use `@` to hide the command line
  $(call log_error, "It works, yey!")

uninstall:
  @[ "$(AWS_PROFILE)" ] || $(call log_error, "AWS_PROFILE not set!")
  ....
  $(call log_error, "Nuked!")

Short Answer - E

Answer isE given that the rest are plainly wrong, but ..

Long Answer - It isn't that simple; it depends ...

Simple fact is, the garbage collector may never decide to garbage collection every single object that is a viable candidate for collection, not unless memory pressure is extremely high. And then there is the fact that Java is just as susceptible to memory leaks as any other language, they are just harder to cause, and thus harder to find when you do cause them!

The following article has many good details on how memory management works and doesn't work and what gets take up by what. How generational Garbage Collectors work and Thanks for the Memory ( Understanding How the JVM uses Native Memory on Windows and Linux )

If you read the links, I think you will get the idea that memory management in Java isn't as simple as a multiple choice question.

you can use this http://www.md5decrypt.org/ or this http://md5.gromweb.com/ it will decrypt your md5 code

This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.

THIS ANSWER IS FOR ANIMATIONS ONLY


If you wanna implement the AND logic, you should use MultiTrigger, here is an example:

Suppose we want to do some actions if the property Text="" (empty string) AND IsKeyboardFocused="False", then your code should look like the following:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
        <MultiTrigger.EnterActions>
            <!-- Your actions here -->
        </MultiTrigger.EnterActions>
</MultiTrigger>

If you wanna implement the OR logic, there are couple of ways, and it depends on what you try to do:

The first option is to use multiple Triggers.
So, suppose you wanna do something if either Text="" OR IsKeyboardFocused="False",
then your code should look something like this:

<Trigger Property="IsEnabled" Value="false">
    <Setter Property="Opacity" TargetName="border" Value="0.56"/>
</Trigger>
<Trigger Property="IsMouseOver" Value="true">
    <Setter Property="BorderBrush" TargetName="border" 
            Value="{StaticResource TextBox.MouseOver.Border}"/>
</Trigger>

But the problem in this is what will I do if i wanna do something if either Text ISN'T null OR IsKeyboard="True"? This can be achieved by the second approach:
Recall De Morgan's rule, that says !(!x && !y) = x || y.
So we'll use it to solve the previous problem, by writing a multi trigger that it's triggered when Text="" and IsKeyboard="True", and we'll do our actions in EXIT ACTIONS, like this:

<MultiTrigger>
    <MultiTrigger.Conditions>
        <Condition Property="Text" Value="" />
        <Condition Property="IsKeyboardFocused" Value="False" />
    </MultiTrigger.Conditions>
    <MultiTrigger.ExitActions>
        <!-- Do something here -->
    </MultiTrigger.ExitActions>
</MultiTrigger>

If you are using PDO, you can use the PDO::quote method.

Without walker menu it's not possible to directly add it. You can, however, add it by javascript.

$('#menu > li').addClass('class_name');

You can also use css rules:

position: fixed ; and top: 0px ;

on your menu tag.

if you create a console application, console will stay opened until you close the application.

if you already creat an application and you dont know how to open a console, you can change the subsystem as Console(/Subsystem:Console) in project configurations -> linker -> system.

The most flexible approach would be using this method

Arr::sortByKeys(array $array, $keys, bool $assoc = true): array

here's why:

• You can sort by any key (also nested like 'key1.key2.key3' or ['k1', 'k2', 'k3'])

• Works both on associative and not associative arrays ($assoc flag)

• It doesn't use reference - return new sorted array

In your case it would be as simple as:

$sortedArray = Arr::sortByKeys($array, 'order');

This method is a part of this library.

Windows 10 Solution:

For me this issue was due to downloading and creating an AVD using Android Studio and then trying to use that virtual device with the Ionic command line. I resolved this by deleting all existing emulators and creating a new one from the command line.

(the avdmanager file typically lives in C:\Users\\Android\sdk\tools\bin)

List existing emulators: avdmanager list avd

Delete an existing emulator: avdmanager delete avd -n emulator_name

Add system image: sdkmanager "system-images;android-24;default;x86_64"

Create new emulator: sdkmanager "system-images;android-27;google_apis_playstore;x86"

select month(dateField), year(dateField)

You use standard syntax (using this like a method) to pick the overload, inside the class:

class Foo 
{
    private int id;
    private string name;

    public Foo() : this(0, "") 
    {
    }

    public Foo(int id, string name) 
    {
        this.id = id;
        this.name = name;
    }

    public Foo(int id) : this(id, "") 
    {
    }

    public Foo(string name) : this(0, name) 
    {
    }
}

then:

Foo a = new Foo(), b = new Foo(456,"def"), c = new Foo(123), d = new Foo("abc");

Note also:

• you can chain to constructors on the base-type using base(...)
• you can put extra code into each constructor
• the default (if you don't specify anything) is base()

For "why?":

• code reduction (always a good thing)

• necessary to call a non-default base-constructor, for example:

  SomeBaseType(int id) : base(id) {...}
  

Note that you can also use object initializers in a similar way, though (without needing to write anything):

SomeType x = new SomeType(), y = new SomeType { Key = "abc" },
         z = new SomeType { DoB = DateTime.Today };

There’s also SenTestingKitAsync that lets you write code like this:

- (void)testAdditionAsync {
    [Calculator add:2 to:2 block^(int result) {
        STAssertEquals(result, 4, nil);
        STSuccess();
    }];
    STFailAfter(2.0, @"Timeout");
}

(See objc.io article for details.) And since Xcode 6 there’s an AsynchronousTesting category on XCTest that lets you write code like this:

XCTestExpectation *somethingHappened = [self expectationWithDescription:@"something happened"];
[testedObject doSomethigAsyncWithCompletion:^(BOOL succeeded, NSError *error) {
    [somethingHappened fulfill];
}];
[self waitForExpectationsWithTimeout:1 handler:NULL];

Remove key and then add again the modified key, value pair as shown below :

    JSONObject js = new JSONObject();
    js.put("name", "rai");

    js.remove("name");
    js.put("name", "abc");

I haven't used your example; but conceptually its same.

The set statement doesn't treat spaces the way you expect; your variable is really named Pathname[space] and is equal to [space]C:\Program Files.

Remove the spaces from both sides of the = sign, and put the value in double quotes:

set Pathname="C:\Program Files"

Also, if your command prompt is not open to C:\, then using cd alone can't change drives.

Use

cd /d %Pathname%

or

pushd %Pathname%

instead.

Make sure your body has a height, f.ex:

body { 
    background: url(/img/debut_dark.png) repeat;
    min-height: 100%;
}

Here in my sample I find out the solution of this, because I had the same problem with updates and subquerys:

UPDATE
    A
SET
    A.ValueToChange = B.NewValue
FROM
    (
        Select * From C
    ) B
Where 
    A.Id = B.Id

If your setting.py files fill are correct,you can try to arrive manage.py files proceed call danjgo.setup() in main method . Then run manage.py ,finally again run project ,the issue could disappear.

As to me, i need to caffe to my python path. I can add it's path to the file /home/xy/.bashrc by add

export PYTHONPATH=/home/xy/caffe-master/python:$PYTHONPATH.

to my /home/xy/.bashrc file.

But when I use pycharm, the path is still not in.

So I can add path to PYTHONPATH variable, by run -> edit Configuration.

The easiest way is to use to_datetime:

df['col'] = pd.to_datetime(df['col'])

It also offers a dayfirst argument for European times (but beware this isn't strict).

Here it is in action:

In [11]: pd.to_datetime(pd.Series(['05/23/2005']))
Out[11]:
0   2005-05-23 00:00:00
dtype: datetime64[ns]

You can pass a specific format:

In [12]: pd.to_datetime(pd.Series(['05/23/2005']), format="%m/%d/%Y")
Out[12]:
0   2005-05-23
dtype: datetime64[ns]

You can use the expandable list view explained in API demos to show groups

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList1.html.

To animate the list items motion, you will have to override the getView method and apply translate animation on each list item. The values for animation depend on the position of each list item. This was something which i tried on a simple list view long time back.

<div class="tabbable">
<ul class="nav nav-tabs">
    <li class="active"><a href="#aaa" data-toggle="tab">AAA</a></li>
    <li><a href="#bbb" data-toggle="tab">BBB</a></li>
    <li><a href="#ccc" data-toggle="tab">CCC</a></li>
</ul>
<div class="tab-content" id="tabs">
    <div class="tab-pane fade active in" id="aaa">...Content...</div>
    <div class="tab-pane" id="bbb">...Content...</div>
    <div class="tab-pane" id="ccc">...Content...</div>
</div>
</div>   

Add active class to any li element you want to be active after page load. And also adding active class to content div is needed ,fade in classes are useful for a smooth transition.

theller's solution for wget is really useful, however, i found it does not print out the progress throughout the downloading process. It's perfect if you add one line after the print statement in reporthook.

import sys, urllib

def reporthook(a, b, c):
    print "% 3.1f%% of %d bytes\r" % (min(100, float(a * b) / c * 100), c),
    sys.stdout.flush()
for url in sys.argv[1:]:
    i = url.rfind("/")
    file = url[i+1:]
    print url, "->", file
    urllib.urlretrieve(url, file, reporthook)
print

Look at the DefaultTableModel for a simple model that you can use:

http://java.sun.com/javase/6/docs/api/javax/swing/table/DefaultTableModel.html

This extends the AbstractTableModel, but should be sufficient for basic purposes. You can always extend AbstractTableModel and create your own. Make sure you set it on the JTable as well.

http://java.sun.com/javase/6/docs/api/javax/swing/table/AbstractTableModel.html

Look at the basic Sun tutorial for more information on using the JTable with the table model:

Best to read the wordpress documentation on this https://wordpress.org/support/article/changing-file-permissions/

• All files should be owned by the actual user's account, not the user account used for the httpd process
• Group ownership is irrelevant, unless there's specific group requirements for the web-server process permissions checking. This is not usually the case.
• All directories should be 755 or 750.
• All files should be 644 or 640. Exception: wp-config.php should be 440 or 400 to prevent other users on the server from reading it.
• No directories should ever be given 777, even upload directories. Since the php process is running as the owner of the files, it gets the owners permissions and can write to even a 755 directory.

I was able to slightly improve Jai's answer to work in the case of you having more than one button dropdown with a pretty good presentation that works with bootstrap 3:

Code for The Button

<div class="btn-group">
  <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
    Option: <span class="selection">Option 1</span><span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu">
    <li><a href="#">Option 1</a></li>
    <li><a href="#">Option 2</a></li>
    <li><a href="#">Option 3</a></li>
  </ul>
</div>

JQuery Snippet

$(".dropdown-menu li a").click(function(){

  $(this).parents(".btn-group").find('.selection').text($(this).text());
  $(this).parents(".btn-group").find('.selection').val($(this).text());

});

I also added a 5px margin-right to the "selection" class.

Single line code.. will return true or false

!!(arr.indexOf("val")+1)

The script webpack-dev-server is already installed inside ./node_modules directory. You can either install it again globally by

sudo npm install -g webpack-dev-server

or run it like this

./node_modules/webpack-dev-server/bin/webpack-dev-server.js -d --config webpack.dev.config.js --content-base public/ --progress --colors

. means look it in current directory.

In order to calculate the difference you have to put the + operator,

that way typescript converts the dates to numbers.

+new Date()- +new Date("2013-02-20T12:01:04.753Z")

From there you can make a formula to convert the difference to minutes or hours.

Hope this Code you are looking for HTML:

            <div class="showmore">

Following code works perfect for me

EfficientAdapter adp = (EfficientAdapter) QuickList.getAdapter();
adp.UpdateDataList(EfficientAdapter.MY_DATA);
adp.notifyDataSetChanged();
QuickList.invalidateViews();
QuickList.scrollBy(0, 0);

On the formula menu just Select "Default Values for Nulls" then just add all the fields like the below:

{@Table.Field1} + {@Table.Field2} + {@Table.Field3} + {@Table.Field4} + {@Table.Field5}

Easily consume SOAP Web services with JavaScript -> Listing B

function fncAddTwoIntegers(a, b)
{
    varoXmlHttp = new XMLHttpRequest();
    oXmlHttp.open("POST",
 "http://localhost/Develop.NET/Home.Develop.WebServices/SimpleService.asmx'",
 false);
    oXmlHttp.setRequestHeader("Content-Type", "text/xml");
    oXmlHttp.setRequestHeader("SOAPAction", "http://tempuri.org/AddTwoIntegers");
    oXmlHttp.send(" \
<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' \
xmlns:xsd='http://www.w3.org/2001/XMLSchema' \
 xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> \
  <soap:Body> \
    <AddTwoIntegers xmlns='http://tempuri.org/'> \
      <IntegerOne>" + a + "</IntegerOne> \
      <IntegerTwo>" + b + "</IntegerTwo> \
    </AddTwoIntegers> \
  </soap:Body> \
</soap:Envelope> \
");
    return oXmlHttp.responseXML.selectSingleNode("//AddTwoIntegersResult").text;
}

This may not meet all your requirements but it is a start at actually answering your question. (I switched XMLHttpRequest() for ActiveXObject("MSXML2.XMLHTTP")).

Demo

HTML:

 <form id="form1" runat="server">
   <input type='file' id="imgInp" />
   <img id="blah" src="#" alt="your image" />
</form>

jQuery

function readURL(input) {
    if (input.files && input.files[0]) {
        var reader = new FileReader();

        reader.onload = function (e) {
            $('#blah').attr('src', e.target.result);
        }

        reader.readAsDataURL(input.files[0]);
    }
}

$("#imgInp").change(function(){
    readURL(this);
});

Reference

It's about margins and border. If you use width: auto, then add border, your div won't become bigger than its container. On the other hand, if you use width: 100% and some border, the element's width will be 100% + border or margin. For more info see this.

In this case you use -1.

Your mysql server may not be running. Below explains how to start the server. This is an excerpt from the README file that comes with the mysql download.

After the installation, you can start up MySQL by running the following commands in a terminal window. You must have administrator privileges to perform this task.

If you have installed the Startup Item, use this command:

 shell> sudo /Library/StartupItems/MySQLCOM/MySQLCOM start
 (ENTER YOUR PASSWORD, IF NECESSARY)
 (PRESS CONTROL-D OR ENTER "EXIT" TO EXIT THE SHELL)

If you don't use the Startup Item, enter the following command sequence:

 shell> cd /usr/local/mysql
 shell> sudo ./bin/mysqld_safe
 (ENTER YOUR PASSWORD, IF NECESSARY)
 (PRESS CONTROL-Z)
 shell> bg
 (PRESS CONTROL-D OR ENTER "EXIT" TO EXIT THE SHELL)

The superclass “javax.servlet.http.HttpServlet” was not found on the Java Build Path

Error: "Can not find the tag library descriptor for "http://java.sun.com/jsp/jstl/core"

Solution: Adding the tomcat server in the server runtime will do the job : Project Properties-> Java Build Path-> Add Library -> Select "Server Runtime" from the list-> Next->Select "Apache Tomcat"-> Finish

This solution work for me.

it really depends on how many boarder use in your view , sometimes , just add a UIVIEW which the size is a bit bigger to create the border . the method is faster than produce a view

This should work for every default repo:

git pull origin master

If your default branch is different than master, you will need to specify the branch name:

git pull origin my_default_branch_name

It will make screen design harder as you will no longer be able to predict how wide your controls should be.

Currently evaluation in the console is performed in the context of the main frame in the page and it adheres to the same cross-origin policy as the main frame itself. This means that you cannot access elements in the iframe unless the main frame can. You can still set breakpoints in and debug your code using Scripts panel though.

Update: This is no longer true. See Metagrapher's answer.

this is what i came up with as i was having issues with @asp8811 answer(maybe my own difficulties)

' this will do the put the first 2 sheets in a pdf ' Note each ws should be controlled with page breaks for printing which is a bit fiddly ' this will explicitly put the pdf in the current dir

Sub luxation2()
    Dim Filename As String
    Filename = "temp201"



Dim shtAry()
ReDim shtAry(1) ' this is an array of length 2
For i = 1 To 2
shtAry(i - 1) = Sheets(i).Name
Debug.Print Sheets(i).Name
Next i
Sheets(shtAry).Select
Debug.Print ThisWorkbook.Path & "\"


    ActiveSheet.ExportAsFixedFormat xlTypePDF, ThisWorkbook.Path & "/" & Filename & ".pdf", , , False

End Sub

Google already published a guide on optimization of PHP and the conclusion was:

No getter and setter Optimizing PHP

And no, you must not use magic methods. For PHP, Magic Method are evil. Why?

1. They are hard to debug.
2. There is a negative performance impact.
3. They require writing more code.

PHP is not Java, C++, or C#. PHP is different and plays with different roles.

I find this more idiomatic:

def proc = "ls foo.txt doesnotexist.txt".execute()
assert proc.in.text == "foo.txt\n"
assert proc.err.text == "ls: doesnotexist.txt: No such file or directory\n"

As another post mentions, these are blocking calls, but since we want to work with the output, this may be necessary.

You can use the Grid CSS properties, is the most clear, clean and intuitive way structure your boxes.

#container{_x000D_
    display: grid;_x000D_
    grid-template-columns: 100px auto;_x000D_
    color:white;_x000D_
}_x000D_
#fixed{_x000D_
  background: red;_x000D_
  grid-column: 1;_x000D_
}_x000D_
#remaining{_x000D_
  background: green;_x000D_
  grid-column: 2;_x000D_
}

<div id="container">_x000D_
  <div id="fixed">Fixed</div>_x000D_
  <div id="remaining">Remaining</div>_x000D_
</div>

I've found a simple soluition for this by creating a base activity class , u must extend all your activity classes from this :

public class BaseActivity extends ActionBarActivity {

@Override
protected void onResume() {
    ApplicationStateChecker.view_resumed(this);
    super.onResume();
}

@Override
protected void onStop() {
    ApplicationStateChecker.view_stopped(this);
    super.onStop();

}

@Override
protected void onPause() {
    ApplicationStateChecker.view_paused(this);
    super.onPause();

}

}

ApplicationStateChecker class :

public class ApplicationStateChecker {

private  static final String _pause_string = "paused";
private  static final String _resume_string = "resumed";

private static String _view_lastState;
private static boolean _from_background = true;

public static void view_paused(Activity activity){
    _view_lastState = _pause_string;
}

public static void view_stopped(Activity activity){

    if (  _view_lastState.equals(_pause_string) ){
        //if stop called and last event was pause then app is brought to background
        _from_background = true;
    }  //if

}

public static void view_resumed(Activity activity){

    if (  _from_background ) {
       //Do your stuff here , app is brought to foreground 

    }  //if

    _from_background = false;
    _view_lastState = _resume_string;
}

@NathanClement was a bit faster. Yet, here is the complete code (slightly more elaborate):

Option Explicit

Public Sub ExportWorksheetAndSaveAsCSV()

Dim wbkExport As Workbook
Dim shtToExport As Worksheet

Set shtToExport = ThisWorkbook.Worksheets("Sheet1")     'Sheet to export as CSV
Set wbkExport = Application.Workbooks.Add
shtToExport.Copy Before:=wbkExport.Worksheets(wbkExport.Worksheets.Count)
Application.DisplayAlerts = False                       'Possibly overwrite without asking
wbkExport.SaveAs Filename:="C:\tmp\test.csv", FileFormat:=xlCSV
Application.DisplayAlerts = True
wbkExport.Close SaveChanges:=False

End Sub

You can use:

SELECT SUBDATE(NOW(), 1);

or

SELECT SUBDATE(NOW(), INTERVAL 1 DAY);

or

SELECT NOW() - INTERVAL 1 DAY;

or

SELECT DATE_SUB(NOW(), INTERVAL 1 DAY);

According to ahmed_khan_89's answer, you can put you "copy code" inside product flavors.

productFlavors {
    staging {
        applicationId = "com.demo.staging"

        println "Using Staging google-service.json"
        copy {
            from 'src/staging/'
            include '*.json'
            into '.'
        }
    }
    production {
        applicationId = "com.demo.production"

        println "Using Production google-service.json"
        copy {
            from 'src/production/'
            include '*.json'
            into '.'
        }
    }
}

Then you don't have to switch settings manually.

I like Consolas a lot. This top-10 list is a good resource for others. It includes examples and descriptions.

Daniel's comment as an answer:

"escaping only occurs in Django during template rendering. Therefore, there's no need for an unescape - you just tell the templating engine not to escape. either {{ context_var|safe }} or {% autoescape off %}{{ context_var }}{% endautoescape %}"

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

Use the Process class. The MSDN documentation has an example how to use it.

**write this before adding view to dialog.**

dialog1.requestWindowFeature(Window.FEATURE_NO_TITLE);
