Please use the following

ddlCity.Items.Clear();

Similar as shown and mentioned:

Notes: Take into consideration that Cells will change their color (only) after the DataGridView Control is Visible. Therefore one practical solution would be using the:

VisibleChanged Event

In case you wish to keep your style when creating new Rows; also subscribe the:

RowsAdded Event

Example bellow:

///<summary> Instantiate the DataGridView Control. </summary>
private DataGridView dgView = new DataGridView;

///<summary> Method to configure DataGridView Control. </summary>
private void DataGridView_Configuration()
{
    // In this case the method just contains the VisibleChanged event subscription.

    dgView.VisibleChanged += DgView_VisibleChanged;

    // Uncomment line bellow in case you want to keep the style when creating new rows.
    // dgView.RowsAdded += DgView_RowsAdded;
}

///<summary> The actual Method that will re-design (Paint) DataGridView Cells. </summary>
 private void DataGridView_PaintCells()
 {
     int nrRows = dgView.Rows.Count;
     int nrColumns = dgView.Columns.Count;
     Color green = Color.LimeGreen;

     // Iterate over the total number of Rows
     for (int row = 0; row < nrRows; row++)
     {
         // Iterate over the total number of Columns
         for (int col = 0; col < nrColumns; col++) 
         {
             // Paint cell location (column, row)
             dgView[col, row].Style.BackColor = green;
         }
     }
 }

///<summary> The DataGridView VisibleChanged Event. </summary>
private void DataGridView_VisibleChanged(object sender, EventArgs e)
{
    DataGridView_PaintCells();
}

/// <summary> Occurrs when a new Row is Created. </summary>
/// <param name="sender"></param>
/// <param name="e"></param>
private void DataGridView_RowsAdded(object sender, DataGridViewRowsAddedEventArgs e)
{ 
    DataGridView_PaintCells(); 
}

Finally: Just call the DataGridView_Configuration() (method)
i.e: Form Load Event.

foreach (DataGridViewRow row in GridView2.Rows)
            {
                if ( ! row.IsNewRow)
                {
                    for (int i = 0; i < GridView2.Columns.Count; i++)
                    {
                        String header = GridView2.Columns[i].HeaderText;
                        String cellText = Convert.ToString(row.Cells[i].Value);
                    }
                }
            }

Here Before Iterating for cell Values need to check for NewRow.

            TextBox txt_NoOfExEmp = (TextBox)gvr.FindControl("txtNoOfExEmp");
            lbl_TotNoOfExEmp.Text = (Convert.ToDouble(txt_NoOfExEmp.Text) + Convert.ToDouble(lbl_TotNoOfExEmp.Text)).ToString();
            lbl_TotNoOfExEmp.Text = string.Format("{0:F0}", Decimal.Parse(lbl_TotNoOfExEmp.Text));

These are all great suggestions, but if I were you, I would do this in your view model. Within your view model, you can create a relay command that you can then bind to the click event in your item template. To determine if the same item was selected, you can store a reference to your selected item in your view model. I like to use MVVM Light to handle the binding. This makes your project much easier to modify in the future, and allows you to set the binding in Blend.

When all is said and done, your XAML will look like what Sergey suggested. I would avoid using the code behind in your view. I'm going to avoid writing code in this answer, because there is a ton of examples out there.

Here is one: How to use RelayCommand with the MVVM Light framework

If you require an example, please comment, and I will add one.

~Cheers

I said I wasn't going to do an example, but I am. Here you go.

1) In your project, add MVVM Light Libraries Only.

2) Create a class for your view. Generally speaking, you have a view model for each view (view: MainWindow.xaml && viewModel: MainWindowViewModel.cs)

3) Here is the code for the very, very, very basic view model:

All included namespace (if they show up here, I am assuming you already added the reference to them. MVVM Light is in Nuget)

using GalaSoft.MvvmLight;
using GalaSoft.MvvmLight.CommandWpf;
using System;
using System.Collections.Generic;
using System.Collections.ObjectModel;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

Now add a basic public class:

/// <summary>
/// Very basic model for example
/// </summary>
public class BasicModel 
{
    public string Id { get; set; }
    public string Text { get; set; }

    /// <summary>
    /// Constructor
    /// </summary>
    /// <param name="text"></param>
    public BasicModel(string text)
    {
        this.Id = Guid.NewGuid().ToString();
        this.Text = text;
    }
}

Now create your viewmodel:

public class MainWindowViewModel : ViewModelBase
{
    public MainWindowViewModel()
    {
        ModelsCollection = new ObservableCollection<BasicModel>(new List<BasicModel>() {
            new BasicModel("Model one")
            , new BasicModel("Model two")
            , new BasicModel("Model three")
        });
    }

    private BasicModel _selectedBasicModel;

    /// <summary>
    /// Stores the selected mode.
    /// </summary>
    /// <remarks>This is just an example, may be different.</remarks>
    public BasicModel SelectedBasicModel 
    {
        get { return _selectedBasicModel; }
        set { Set(() => SelectedBasicModel, ref _selectedBasicModel, value); }
    }

    private ObservableCollection<BasicModel> _modelsCollection;

    /// <summary>
    /// List to bind to
    /// </summary>
    public ObservableCollection<BasicModel> ModelsCollection
    {
        get { return _modelsCollection; }
        set { Set(() => ModelsCollection, ref _modelsCollection, value); }
    }        
}

In your viewmodel, add a relaycommand. Please note, I made this async and had it pass a parameter.

    private RelayCommand<string> _selectItemRelayCommand;
    /// <summary>
    /// Relay command associated with the selection of an item in the observablecollection
    /// </summary>
    public RelayCommand<string> SelectItemRelayCommand
    {
        get
        {
            if (_selectItemRelayCommand == null)
            {
                _selectItemRelayCommand = new RelayCommand<string>(async (id) =>
                {
                    await selectItem(id);
                });
            }

            return _selectItemRelayCommand;
        }
        set { _selectItemRelayCommand = value; }
    }

    /// <summary>
    /// I went with async in case you sub is a long task, and you don't want to lock you UI
    /// </summary>
    /// <returns></returns>
    private async Task<int> selectItem(string id)
    {
        this.SelectedBasicModel = ModelsCollection.FirstOrDefault(x => x.Id == id);
        Console.WriteLine(String.Concat("You just clicked:", SelectedBasicModel.Text));
        //Do async work

        return await Task.FromResult(1);
    }

In the code behind for you view, create a property for you viewmodel and set the datacontext for your view to the viewmodel (please note, there are other ways to do this, but I am trying to make this a simple example.)

public partial class MainWindow : Window
{
    public MainWindowViewModel MyViewModel { get; set; }
    public MainWindow()
    {
        InitializeComponent();

        MyViewModel = new MainWindowViewModel();
        this.DataContext = MyViewModel;
    }
}

In your XAML, you need to add some namespaces to the top of your code

<Window x:Class="Basic_Binding.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"
    xmlns:Custom="clr-namespace:GalaSoft.MvvmLight;assembly=GalaSoft.MvvmLight"
    Title="MainWindow" Height="350" Width="525">

I added "i" and "Custom."

Here is the ListView:

<ListView 
        Grid.Row="0" 
        Grid.Column="0" 
        HorizontalContentAlignment="Stretch"
        ItemsSource="{Binding ModelsCollection}"
        ItemTemplate="{DynamicResource BasicModelDataTemplate}">
    </ListView>

Here is the ItemTemplate for the ListView:

<DataTemplate x:Key="BasicModelDataTemplate">
        <Grid>
            <TextBlock Text="{Binding Text}">
                <i:Interaction.Triggers>
                    <i:EventTrigger EventName="MouseLeftButtonUp">
                        <i:InvokeCommandAction 
                            Command="{Binding DataContext.SelectItemRelayCommand, 
                                RelativeSource={RelativeSource FindAncestor, 
                                        AncestorType={x:Type ItemsControl}}}"
                            CommandParameter="{Binding Id}">                                
                        </i:InvokeCommandAction>
                    </i:EventTrigger>
                </i:Interaction.Triggers>
            </TextBlock>
        </Grid>
    </DataTemplate>

Run your application, and check out the output window. You can use a converter to handle the styling of the selected item.

This may seem really complicated, but it makes life a lot easier down the road when you need to separate your view from your ViewModel (e.g. develop a ViewModel for multiple platforms.) Additionally, it makes working in Blend 10x easier. Once you develop your ViewModel, you can hand it over to a designer who can make it look very artsy :). MVVM Light adds some functionality to make Blend recognize your ViewModel. For the most part, you can do just about everything you want to in the ViewModel to affect the view.

If anyone reads this, I hope you find this helpful. If you have questions, please let me know. I used MVVM Light in this example, but you could do this without MVVM Light.

If you have Model or transfer object passed to GET method but still have this error, check naming of your variables. Use entity/transfer object names in camelcase. I had BusinessTripDTO object and named it 'trip' for short. It caused this error to occure, even I had all other parts in place. Renaming varaibles to businessTripDTO in Java and Thymeleaf solved this problem for me.

add HeaderStyle in your bound field:

    <asp:BoundField HeaderText="UserId"
                DataField="UserId" 
                SortExpression="UserId">

                <HeaderStyle Width="200px" />

</asp:BoundField>

Try this:

foreach(GridViewRow row in GridView1.Rows) {
    if(row.RowType == DataControlRowType.DataRow) {
        HyperLink myHyperLink = row.FindControl("myHyperLinkID") as HyperLink;
    }
}

If you are handling RowDataBound event, it's like this:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if(e.Row.RowType == DataControlRowType.DataRow)
    {
        HyperLink myHyperLink = e.Row.FindControl("myHyperLinkID") as HyperLink;
    }
}

Depends, if i remember correctly i think asp.net won't render the html object out when you set visible to false.

If you want to be able to control it from the client side, then you better just include the css value to set it invisible rather than using visible =false.

This is working code

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            { 
                    DropDownList1.DataTextField = "user_name";
                    DropDownList1.DataValueField = "user_id";
                    DropDownList1.DataSource = getData();// get the data into the list you can set it
                    DropDownList1.DataBind();

    DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("your default selected text"));
            }
        }

<ComboBox Text="Something">
            <ComboBoxItem Content="Item1"></ComboBoxItem >
            <ComboBoxItem Content="Item2"></ComboBoxItem >
            <ComboBoxItem Content="Item3"></ComboBoxItem >
</ComboBox>

RegisteredClientScriptBlock adds the script at the top of the page on the post-back with no assurance about the order, meaning that either the call is being injected after the function declaration (your js file with the function is inlined after your call) or when the script tries to execute the div is probably not there yet 'cause the page is still rendering. A good idea is probably to simulate the two scenarios I described above on firebug and see if you get similar errors.

My guess is this would work if you append the script at the bottom of the page with RegisterStartupScript - worth a shot at least.

Anyway, as an alternative solution if you add the runat="server" attribute to the div you will be able to access it by its id in the codebehind (without reverting to js - how cool that might be), and make it disappear like this:

data.visible = false

I had a similar problem with an SEHException that was thrown when my program first used a native dll wrapper. Turned out that the native DLL for that wrapper was missing. The exception was in no way helpful in solving this. What did help in the end was running procmon in the background and checking if there were any errors when loading all the necessary DLLs.

private T GetHeaderControl<T>(Repeater rp, string id) where T : Control
{
    T returnValue = null;
    if (rp != null && !String.IsNullOrWhiteSpace(id))
    {
        returnValue = rp.Controls.Cast<RepeaterItem>().Where(i => i.ItemType == ListItemType.Header).Select(h => h.FindControl(id) as T).Where(c => c != null).FirstOrDefault();
    }
    return returnValue;
}

Finds and casts the control. (Based on Piyey's VB answer)

I think what you want to do is this:

<asp:DropDownList ID="DropDownList1" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Text="--Select One--" Value="" />   
</asp:DropDownList>

Make sure the 'AppendDataBoundItems' is set to true or else you will clear the '--Select One--' list item when you bind your data.

If you have the 'AutoPostBack' property of the drop down list set to true you will have to also set the 'CausesValidation' property to true then use a 'RequiredFieldValidator' to make sure the '--Select One--' option doesn't cause a postback.

<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="DropDownList1"></asp:RequiredFieldValidator>

Thnaks for answer. I tried it myself too to an Empty Project and - lo behold allmighty creator of heaven and seven seas - it worked. I originally had ListBox inside which was inside of root . For some reason ListBox doesn't like being inside of StackPanel, at all! =)

When you use a TemplateField and bind literal text to it like you are doing, asp.net will actually insert a control FOR YOU! It gets put into a DataBoundLiteralControl. You can see this if you look in the debugger near your line of code that is getting the empty text.

So, to access the information without changing your template to use a control, you would cast like this:

string percentage = ((DataBoundLiteralControl)e.Row.Cells[7].Controls[0]).Text;

That will get you your text!

In my case, PATH was properly SET but PATHEXT has been cleared by me by mistake with .exe extension. That why window can't find java or anything .exe application from command prompt. Hope it can help someone.

I was also having this problem, with an Ad-Hoc iPad application, when trying to install it on a iOS 6 device.

What fixed it for me was to click on the project in XCode, and change the "iOS Deployment Target" setting from 5.1 to 6.0.

And there was silly me thinking that iOS 5.1 apps would run on a iOS 6.0 device.

am not sure if I fully understand the issue, but guess it's related to the one I had, am using Qt with TCP socket communication, all non-blocking, both Windows and Linux..

wanted to get a quick notification when an already connected client failed or completely disappeared, and not waiting the default 900+ seconds until the disconnect signal got raised. The trick to get this working was to set the TCP_USER_TIMEOUT socket option of the SOL_TCP layer to the required value, given in milliseconds.

this is a comparably new option, pls see http://tools.ietf.org/html/rfc5482, but apparently it's working fine, tried it with WinXP, Win7/x64 and Kubuntu 12.04/x64, my choice of 10 s turned out to be a bit longer, but much better than anything else I've tried before ;-)

the only issue I came across was to find the proper includes, as apparently this isn't added to the standard socket includes (yet..), so finally I defined them myself as follows:

#ifdef WIN32
    #include <winsock2.h>
#else
    #include <sys/socket.h>
#endif

#ifndef SOL_TCP
    #define SOL_TCP 6  // socket options TCP level
#endif
#ifndef TCP_USER_TIMEOUT
    #define TCP_USER_TIMEOUT 18  // how long for loss retry before timeout [ms]
#endif

setting this socket option only works when the client is already connected, the lines of code look like:

int timeout = 10000;  // user timeout in milliseconds [ms]
setsockopt (fd, SOL_TCP, TCP_USER_TIMEOUT, (char*) &timeout, sizeof (timeout));

and the failure of an initial connect is caught by a timer started when calling connect(), as there will be no signal of Qt for this, the connect signal will no be raised, as there will be no connection, and the disconnect signal will also not be raised, as there hasn't been a connection yet..

As already mentioned earlier. You could autowire Environment:

@Autowire
private Environment environment;

only you could do check for the needed environment much easier:

if (environment.acceptsProfiles(Profiles.of("test"))) {
    doStuffForTestEnv();
} else {
    doStuffForOtherProfiles();
}

As far as I know there is no option to create global configuration for java applications. You always create a duplicate of the configuration.

Also, if you are using PDE (for plugin development), you can create target platform using windows -> Preferences -> Plug-in development -> Target Platform. Edit has options for program/vm arguments.

Hope this helps

HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.

The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.

Paxdiablo's answer is absolutely correct.

To avoid writing the return value 1 twice, I would use this instead:

=IF(OR(ISBLANK(A1),TRIM(A1)=""),1,0)

The question is simple: given a C++ array (e.g. x as in int x[10]), how would you get the number of elements in it?

An obvious solution is the following macro (definition 1):

#define countof( array ) ( sizeof( array )/sizeof( array[0] ) )

I cannot say this isn’t correct, because it does give the right answer when you give it an array. However, the same expression gives you something bogus when you supply something that is not an array. For example, if you have

int * p;

then countof( p ) always give you 1 on a machine where an int pointer and an int have the same size (e.g. on a Win32 platform).

This macro also wrongfully accepts any object of a class that has a member function operator[]. For example, suppose you write

class IntArray {
private:
    int * p;
    size_t size;
public:
    int & operator [] ( size_t i );
} x;

then sizeof( x ) will be the size of the x object, not the size of the buffer pointed to by x.p. Therefore you won’t get a correct answer by countof( x ).

So we conclude that definition 1 is not good because the compiler does not prevent you from misusing it. It fails to enforce that only an array can be passed in.

What is a better option?

Well, if we want the compiler to ensure that the parameter to countof is always an array, we have to find a context where only an array is allowed. The same context should reject any non-array expression.

Some beginners may try this (definition 2):

template <typename T, size_t N>
size_t countof( T array[N] )
{
   return N;
}

They figure, this template function will accept an array of N elements and return N.

Unfortunately, this doesn’t compile because C++ treats an array parameter the same as a pointer parameter, i.e. the above definition is equivalent to:

template <typename T, size_t N>
size_t countof( T * array )
{
    return N;
}

It now becomes obvious that the function body has no way of knowing what N is.

However, if a function expects an array reference, then the compiler does make sure that the size of the actual parameter matches the declaration. This means we can make definition 2 work with a minor modification (definition 3):

template <typename T, size_t N>
size_t countof( T (&array)[N] )
{
    return N;
}

This countof works very well and you cannot fool it by giving it a pointer. However, it is a function, not a macro. This means you cannot use it where a compile time constant is expected. In particular, you cannot write something like:

int x[10];

int y[ 2*countof(x) ]; // twice as big as x

Can we do anything about it?

Someone (I don’t know who it is – I just saw it in a piece of code from an unknown author) came up with a clever idea: moving N from the body of the function to the return type (e.g. make the function return an array of N elements), then we can get the value of N without actually calling the function.

To be precise, we have to make the function return an array reference, as C++ does not allow you to return an array directly.

The implementation of this is:

template <typename T, size_t N>
char ( &_ArraySizeHelper( T (&array)[N] ))[N];

#define countof( array ) (sizeof( _ArraySizeHelper( array ) ))

Admittedly, the syntax looks awful. Indeed, some explanation is necessary.

First, the top-level stuff

char ( &_ArraySizeHelper( ... ))[N];

says _ArraySizeHelper is a function that returns a reference (note the &) to a char array of N elements.

Next, the function parameter is

T (&array)[N]

which is a reference to a T array of N elements.

Finally, countof is defined as the size of the result of the function _ArraySizeHelper. Note we don’t even need to define _ArraySizeHelper(), -- a declaration is enough.

With this new definition,

int x[10];

int y[ 2*countof(x) ]; // twice as big as x

becomes valid, just as we desire.

Am I happy now? Well, I think this definition is definitely better than the others we have visited, but it is still not quite what I want. For one thing, it doesn’t work with types defined inside a function. That’s because the template function _ArraySizeHelper expects a type that is accessible in the global scope.

I don’t have a better solution. If you know one, please let me know.

Run in command prompt.

pip list

Check what version you have installed on your system if you have an old version.

Try to uninstall the package...

pip uninstall requests

Try after to install it:

Make sure you specify pass header=None and add usecols=[3,6] for the 4th and 7th columns.

As others have mentioned, you should avoid macros whenever possible. They are dangerous in the presence of side effects if the macro arguments are evaluated more than once. If you know the type of the arguments (or can use C++0x auto feature), you could use temporaries to enforce single evaluation.

Another problem: the order in which multiple evaluations happen may not be what you expect!

Consider this code:

#include <iostream>
using namespace std;

int foo( int & i ) { return i *= 10; }
int bar( int & i ) { return i *= 100; }

#define BADMACRO( X, Y ) do { \
    cout << "X=" << (X) << ", Y=" << (Y) << ", X+Y=" << ((X)+(Y)) << endl; \
    } while (0)

#define MACRO( X, Y ) do { \
    int x = X; int y = Y; \
    cout << "X=" << x << ", Y=" << y << ", X+Y=" << ( x + y ) << endl; \
    } while (0)

int main() {
    int a = 1; int b = 1;
    BADMACRO( foo(a), bar(b) );
    a = 1; b = 1;
    MACRO( foo(a), bar(b) );
    return 0;
}

And it's output as compiled and run on my machine:

X=100, Y=10000, X+Y=110
X=10, Y=100, X+Y=110

Support for interactive graphics is much better in matlab than in R. I hate matlab as a language, but I get jealous when I see how its users can explore data with mouse operations, while I'm busy repeating commands with new values for xlim etc. Matlab also handles multi-panel plots much better than any of the R methods for the task. Generally, R graphics has a 1960s feel. It's fine for publication, but not the best solution for interactive exploration of data.

finalize() is called just before garbage collection. It is not called when an object goes out of scope. This means that you cannot know when or even if finalize() will be executed.

Example:

If your program end before garbage collector occur, then finalize() will not execute. Therefore, it should be used as backup procedure to ensure the proper handling of other resources, or for special use applications, not as the means that your program uses in its normal operation.

In a column with blanks, you can get the last value with

=+sort(G:G,row(G:G)*(G:G<>""),)

Just wanted to point out that the built-in sink function has good examples of different ways to set arguments in a function:

> sink
function (file = NULL, append = FALSE, type = c("output", "message"),
    split = FALSE)
{
    type <- match.arg(type)
    if (type == "message") {
        if (is.null(file))
            file <- stderr()
        else if (!inherits(file, "connection") || !isOpen(file))
            stop("'file' must be NULL or an already open connection")
        if (split)
            stop("cannot split the message connection")
        .Internal(sink(file, FALSE, TRUE, FALSE))
    }
    else {
        closeOnExit <- FALSE
        if (is.null(file))
            file <- -1L
        else if (is.character(file)) {
            file <- file(file, ifelse(append, "a", "w"))
            closeOnExit <- TRUE
        }
        else if (!inherits(file, "connection"))
            stop("'file' must be NULL, a connection or a character string")
        .Internal(sink(file, closeOnExit, FALSE, split))
    }
}

If you do not want to install sqlplus on your server/machine then the following command-line tool can be your friend. It is a simple Java application, only Java 8 that you need in order to you can execute this tool.

The tool can be used to run any SQL from the Linux bash or Windows command line.

Example:

java -jar sql-runner-0.2.0-with-dependencies.jar \
     -j jdbc:oracle:thin:@//oracle-db:1521/ORCLPDB1.localdomain \
     -U "SYS as SYSDBA" \
     -P Oradoc_db1 \
      "select 1 from dual"

Documentation is here.

You can download the binary file from here.

if you are using jquery-ui 1.11.4:

var tooltip = $.widget( "ui.tooltip", {
    version: "1.11.4",
    options: {
        content: function() {
            // support: IE<9, Opera in jQuery <1.7
            // .text() can't accept undefined, so coerce to a string
            var title = $( this ).attr( "title" ) || "";
            // Escape title, since we're going from an attribute to raw HTML
Replace-->  //return $( "<a>" ).text( title ).html();
by -->      return $( "<a>" ).html( title );
             },

Clean, fast and simple without useless code:

function consolelog($data) {
    echo "<script>console.log('".$data."');</script>";
}

if you are using properties file you can add following line there:

spark.jars=jars/your_jar1.jar,...

assuming that

<your root from where you run spark-submit>
  |
  |-jars
      |-your_jar1.jar

This is what worked for me:

In the build.gradle file, setting the minSdkVersion under defaultConfig:

Good Luck...

I found this problem when I changed my SVN password.

How to resolve First, remove Subversion folder in {Documents and Settings}{user login}\Application Data\Subversion -> It doesn't work

After, rename my current user login profile from {Documents and Settings}{user login} to {Documents and Settings}{user login}_bakup and login agian -> It work...

I assumed -> SVN or JavaHL bind authorized user with {user login} or keep it in user profile of window.

Magento 1.x

(magento 2 example provided below)

sectionName, groupName and fieldName are present in etc/system.xml file of the module.

PHP Syntax:

Mage::getStoreConfig('sectionName/groupName/fieldName');

From within an editor in the admin, such as the content of a CMS Page or Static Block; the description/short description of a Catalog Category, Catalog Product, etc.

{{config path="sectionName/groupName/fieldName"}}

For the "Within an editor" approach to work, the field value must be passed through a filter for the {{ ... }} contents to be parsed out. Out of the box, Magento will do this for Category and Product descriptions, as well as CMS Pages and Static Blocks. However, if you are outputting the content within your own custom view script and want these variables to be parsed out, you can do so like this:

<?php
    $example = Mage::getModel('identifier/name')->load(1);
    $filter  = Mage::getModel('cms/template_filter');
    echo $filter->filter($example->getData('field'));
?>

Replacing identifier/name with the a appropriate values for the model you are loading, and field with the name of the attribute you want to output, which may contain {{ ... }} occurrences that need to be parsed out.

Magento 2.x

From any Block class that extends \Magento\Framework\View\Element\AbstractBlock

$this->_scopeConfig->getValue('sectionName/groupName/fieldName');

Any other PHP class:

If the class (and none of it's parent's) does not inject \Magento\Framework\App\Config\ScopeConfigInterface via the constructor, you'll have to add it to your class.

// ... Remaining class definition above...

/**
 * @var \Magento\Framework\App\Config\ScopeConfigInterface
 */
protected $_scopeConfig;

/**
 * Constructor
 */
public function __construct(
    \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    // ...any other injected classes the class depends on...
) {
  $this->_scopeConfig = $scopeConfig;
  // Remaining constructor logic...
}

// ...remaining class definition below...

Once you have injected it into your class, you can now fetch store configuration values with the same syntax example given above for block classes.

Note that after modifying any class's __construct() parameter list, you may have to clear your generated classes as well as dependency injection directory: var/generation & var/di

Sometime gcc had created as /usr/bin/gcc32. so please create a ln -s /usr/bin/gcc32 /usr/bin/gcc and then compile that ./configure.

Using EntityManager em;

public User getUserById(Long id) {
     return em.getReference(User.class, id);
}

If only the field is required you could go with input:valid

#foo-thing:valid + .msg { visibility: visible!important; }      

 <input type="text" id="foo-thing" required="required">_x000D_
 <span class="msg" style="visibility: hidden;">Yay not empty</span>

See live on jsFiddle

OR negate using #foo-thing:invalid (credit to @SamGoody)

You don't want to throw ex - as this will lose the call stack. See Exception Handling (MSDN).

And yes, the try...catch is doing nothing useful (apart from lose the call stack - so it's actually worse - unless for some reason you didn't want to expose this information).

Load environment variables from a file you create at runtime.

export MYVAR="my_var_outside"
cat > build/env.sh <<EOF
MYVAR=${MYVAR}
EOF

... then in the Dockerfile

ADD build /build
RUN /build/test.sh

where test.sh loads MYVAR from env.sh

#!/bin/bash
. /build/env.sh
echo $MYVAR > /tmp/testfile

I have used like this to show the soft keyboard programatically and this is worked for me to prevent the auto resize of the screen while launching the keyboard.

In manifest:

<activity android:name="XXXActivity" android:windowSoftInputMode="adjustPan">
</activity>

In XXXActvity:

EditText et =  (EditText))findViewById(R.id.edit_text);  
  Timer timer = new Timer();
            TimerTask task = new TimerTask() {

                @Override
                public void run() {
                    InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    inputMethodManager.toggleSoftInputFromWindow(et.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED, 0);

                }
            };
            timer.schedule(task, 200);

I assume this will save others time to search for this problem.

You can use all():

my_list1 = [30,34,56]
my_list2 = [29,500,43]
if all(i >= 30 for i in my_list1):
    print 'yes'
if all(i >= 30 for i in my_list2):
    print 'no'

Note that this includes all numbers equal to 30 or higher, not strictly above 30.

The Lazy Fetch type is by default selected by Hibernate unless you explicitly mark Eager Fetch type. To be more accurate and concise, difference can be stated as below.

FetchType.LAZY = This does not load the relationships unless you invoke it via the getter method.

FetchType.EAGER = This loads all the relationships.

Pros and Cons of these two fetch types.

Lazy initialization improves performance by avoiding unnecessary computation and reduce memory requirements.

Eager initialization takes more memory consumption and processing speed is slow.

Having said that, depends on the situation either one of these initialization can be used.

I was puzzled by this also... didn't like the parentheses that windows puts in when you rename in bulk. In my research I decided to write a script with PowerShell instead. Super easy and worked like a charm. Now I can use it whenever I need to batch process file renaming... which is frequent. I take hundreds of photos and the camera names them IMG1234.JPG etc...

Here is the script I wrote:

# filename: bulk_file_rename.ps1
# by: subcan
# PowerShell script to rename multiple files within a folder to a 
# name that increments without (#)
# create counter
$int = 1
# ask user for what they want
$regex = Read-Host "Regex for files you are looking for? ex. IMG*.JPG "
$file_name = Read-Host "What is new file name, without extension? ex. New Image "
$extension = Read-Host "What extension do you want? ex. .JPG "
# get a total count of the files that meet regex
$total = Get-ChildItem -Filter $regex | measure
# while loop to rename all files with new name
while ($int -le $total.Count)
{
    # diplay where in loop you are
    Write-Host "within while loop" $int  
    # create variable for concatinated new name - 
    # $int.ToString(000) ensures 3 digit number 001, 010, etc
    $new_name = $file_name + $int.ToString(000)+$extension
    # get the first occurance and rename
    Get-ChildItem -Filter $regex | select -First 1 | Rename-Item -NewName $new_name
    # display renamed file name
    Write-Host "Renamed to" $new_name
    # increment counter
    $int++
}

I hope that this is helpful to someone out there.

Use

sudo apt-get install python3-psycopg2

for Python3 )

use ResponseEntity<ResponseBean>

Here you can use ResponseBean or Any java bean as you like to return your api response and it is the best practice. I have used Enum for response. it will return status code and status message of API.

@GetMapping(path = "/login")
public ResponseEntity<ServiceStatus> restApiExample(HttpServletRequest request,
            HttpServletResponse response) {
        String username = request.getParameter("username");
        String password = request.getParameter("password");

        loginService.login(username, password, request);
        return new ResponseEntity<ServiceStatus>(ServiceStatus.LOGIN_SUCCESS,
                HttpStatus.ACCEPTED);
    }

for response ServiceStatus or(ResponseBody)

    public enum ServiceStatus {

    LOGIN_SUCCESS(0, "Login success"),

    private final int id;
    private final String message;

    //Enum constructor
    ServiceStatus(int id, String message) {
        this.id = id;
        this.message = message;
    }

    public int getId() {
        return id;
    }

    public String getMessage() {
        return message;
    }
}

Spring REST API should have below key in response

1. Status Code
2. Message

you will get final response below

{

   "StatusCode" : "0",

   "Message":"Login success"

}

you can use ResponseBody(java POJO, ENUM,etc..) as per your requirement.

try:

$('#search input.keywords').bind('change', function(){
    //this.value.toUpperCase();
    //EDIT: As  Mike Samuel suggested, this will be more appropriate for the job
    this.value = this.value.toLocaleUpperCase();
} );

The configuration file is called applicationhost.config. It's stored here:

My Documents > IIS Express > config

usually, but not always, one of these paths will work

%userprofile%\documents\iisexpress\config\applicationhost.config
%userprofile%\my documents\iisexpress\config\applicationhost.config

Update for VS2019
If you're using Visual Studio 2019+ check this path:

$(solutionDir)\.vs\{projectName}\config\applicationhost.config

Update for VS2015 (credit: @Talon)
If you're using Visual Studio 2015-2017 check this path:

$(solutionDir)\.vs\config\applicationhost.config

In Visual Studio 2015+ you can also configure which applicationhost.config file is used by altering the <UseGlobalApplicationHostFile>true|false</UseGlobalApplicationHostFile> setting in the project file (eg: MyProject.csproj). (source: MSDN forum)

Simple: run these codes:::

 1:: ls -lart/var/run/my*

   2::mkdir /var/run/mysqld

    3::touch /var/run/mysqld/mysqld.sock
    4:ls -lart /var/run/mysqld
    5::chown -R mysql /var/run/mysqld
    6::ls -lart /var/run/mysqld
REstart your mysql server

then finaly type mysql -u root or mysql -u root -p and press enter key. thanks

You can use useEffect/useLayoutEffect to achieve this:

const SomeComponent = () => {
  const [count, setCount] = React.useState(0)

  React.useEffect(() => {
    if (count > 1) {
      document.title = 'Threshold of over 1 reached.';
    } else {
      document.title = 'No threshold reached.';
    }
  }, [count]);

  return (
    <div>
      <p>{count}</p>

      <button type="button" onClick={() => setCount(count + 1)}>
        Increase
      </button>
    </div>
  );
};

More about it over here.

If you are looking for an out of the box solution, check out this custom hook that works like useState but accepts as second parameter a callback function:

// npm install use-state-with-callback

import useStateWithCallback from 'use-state-with-callback';

const SomeOtherComponent = () => {
  const [count, setCount] = useStateWithCallback(0, count => {
    if (count > 1) {
      document.title = 'Threshold of over 1 reached.';
    } else {
      document.title = 'No threshold reached.';
    }
  });

  return (
    <div>
      <p>{count}</p>

      <button type="button" onClick={() => setCount(count + 1)}>
        Increase
      </button>
    </div>
  );
};

As mentioned in other answers ORDER BY 1 orders by the first column.

I came across another example of where you might use it though. We have certain queries which need to be ordered select the same column. You would get a SQL error if ordering by Name in the below.

SELECT Name, Name FROM Segment ORDER BY 1

You asked for Modernizr example, so here you go. This code uses Modernizr to detect whether the 'date' input type is supported. If it isn't supported, then it fails back to JQueryUI datepicker.

Note: You will need to download JQueryUI and possibly change the paths to the CSS and JS files in your own code.

<!DOCTYPE html>
<html>
    <head>
        <title>Modernizer Detect 'date' input type</title>
        <link rel="stylesheet" type="text/css" href="jquery-ui-1.10.3/themes/base/jquery.ui.all.css"/>
        <script type="text/javascript" src="http://ajax.aspnetcdn.com/ajax/modernizr/modernizr-1.7-development-only.js"></script>
        <script type="text/javascript" src="http://code.jquery.com/jquery-1.10.2.min.js"></script>
        <script type="text/javascript" src="jquery-ui-1.10.3/ui/jquery.ui.core.js"></script>
        <script type="text/javascript" src="jquery-ui-1.10.3/ui/jquery.ui.widget.js"></script>
        <script type="text/javascript" src="jquery-ui-1.10.3/ui/jquery.ui.datepicker.js"></script>
        <script type="text/javascript">
            $(function(){
                if(!Modernizr.inputtypes.date) {
                    console.log("The 'date' input type is not supported, so using JQueryUI datepicker instead.");
                    $("#theDate").datepicker();
                }
            });
        </script>
    </head>
    <body>
        <form>
            <input id="theDate" type="date"/>
        </form>
    </body>
</html>

I hope this works for you.

Looks like you might have until the end of 2013 before they officially close it down. http://groups.google.com/group/google-ajax-search-api/browse_thread/thread/6aaa1b3529620610/d70f8eec3684e431?lnk=gst&q=news+api#d70f8eec3684e431

Also, it sounds like they are building a replacement... but it's going to cost you.

I'd say, go to a different service. I think bing has a news API.

You can use CSS transformations to achieve this. A horizontal flip would involve scaling the div like this:

-moz-transform: scale(-1, 1);
-webkit-transform: scale(-1, 1);
-o-transform: scale(-1, 1);
-ms-transform: scale(-1, 1);
transform: scale(-1, 1);

And a vertical flip would involve scaling the div like this:

-moz-transform: scale(1, -1);
-webkit-transform: scale(1, -1);
-o-transform: scale(1, -1);
-ms-transform: scale(1, -1);
transform: scale(1, -1);

DEMO:

span{ display: inline-block; margin:1em; } _x000D_
.flip_H{ transform: scale(-1, 1); color:red; }_x000D_
.flip_V{ transform: scale(1, -1); color:green; }

<span class='flip_H'>Demo text &#9986;</span>_x000D_
<span class='flip_V'>Demo text &#9986;</span>

You Should uninstall the existed python,then download new version.

Just to put the extremely simple answer. Just use the hash location strategy for the router if you are hosting on S3.

export const AppRoutingModule: ModuleWithProviders = RouterModule.forRoot(routes, { useHash: true, scrollPositionRestoration: 'enabled' });

This works for me:

window.addEventListener("beforeunload", function(event) {_x000D_
  event.returnValue = "You may have unsaved Data";_x000D_
});

In sql server I had same problem I wanted to use an and statement only if parameter is false and on true I had to show both values true and false so I used it this way

(T.IsPublic = @ShowPublic or  @ShowPublic = 1)

Use single quotation marks ('):

var val = '@ViewBag.ForSection';
alert(val);

You won't be able to check if char appears at all in some string without atleast going over the string once using loop / recursion ( the built-in methods like indexOf also use a loop )

If the no. of times you look up if a char is in string x is more way more than the length of the string than I would recommend using a Set data structure as that would be more efficient than simply using indexOf

String s = "abc";

// Build a set so we can check if character exists in constant time O(1)
Set<Character> set = new HashSet<>();
int len = s.length();
for(int i = 0; i < len; i++) set.add(s.charAt(i));

// Now we can check without the need of a loop
// contains method of set doesn't use a loop unlike string's contains method
set.contains('a') // true
set.contains('z') // false

Using set you will be able to check if character exists in a string in constant time O(1) but you will also use additional memory ( Space complexity will be O(n) ).

You can get all variables from your jenkins instance. Just visit:

• ${jenkins_host}/env-vars.html
• ${jenkins_host}/pipeline-syntax/globals

Have you checked your folder structure? It seems to me like Express can't find your root directory, which should be a a folder named "site" right under your default directory. Here is how it should look like, according to the tutorial:

node_modules/
  .bin/
  express/
  mongoose/
  path/
site/
  css/
  img/
  js/
  index.html
package.json

For example on my machine, I started getting the same error as you when I renamed my "site" folder as something else. So I would suggest you check that you have the index.html page inside a "site" folder that sits on the same path as your server.js file.

Hope that helps!

You can update your python version to 3.8 in conda using the command

conda install -c anaconda python=3.8

as per https://anaconda.org/anaconda/python. Though not all packages support 3.8 yet, running

conda update --all

may resolve some dependency failures. You can also create a new environment called py38 using this command

conda create -n py38 python=3.8

Edit - note that the conda install option will potentially take a while to solve the environment, and if you try to abort this midway through you will lose your Python installation (usually this means it will resort to non-conda pre-installed system Python installation).

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

It's Simple. I did it this way.

For a wav file

from IPython.display import Audio
from scipy.io.wavfile import read

fs, data = read('StarWars60.wav', mmap=True)  # fs - sampling frequency
data = data.reshape(-1, 1)
Audio(data = data[:, 0], rate = fs)

For mp3 file

import IPython.display import Audio

Audio('audio_file_name.mp3')

Note that you can also set the title directly with javascript, i.e.,

$window.document.title = someTitleYouCreated;

This does not have data binding, but it suffices when putting ng-app in the <html> tag is problematic. (For example, using JSP templates where <head> is defined in exactly one place, yet you have more than one app.)

I think the Vim documentation should've explained the meaning behind the naming of these commands. Just telling you what they do doesn't help you remember the names.

map is the "root" of all recursive mapping commands. The root form applies to "normal", "visual+select", and "operator-pending" modes. (I'm using the term "root" as in linguistics.)

noremap is the "root" of all non-recursive mapping commands. The root form applies to the same modes as map. (Think of the nore prefix to mean "non-recursive".)

(Note that there are also the ! modes like map! that apply to insert & command-line.)

See below for what "recursive" means in this context.

Prepending a mode letter like n modify the modes the mapping works in. It can choose a subset of the list of applicable modes (e.g. only "visual"), or choose other modes that map wouldn't apply to (e.g. "insert").

Use help map-modes will show you a few tables that explain how to control which modes the mapping applies to.

Mode letters:

• n: normal only
• v: visual and select
• o: operator-pending
• x: visual only
• s: select only
• i: insert
• c: command-line
• l: insert, command-line, regexp-search (and others. Collectively called "Lang-Arg" pseudo-mode)

"Recursive" means that the mapping is expanded to a result, then the result is expanded to another result, and so on.

The expansion stops when one of these is true:

1. the result is no longer mapped to anything else.
2. a non-recursive mapping has been applied (i.e. the "noremap" [or one of its ilk] is the final expansion).

At that point, Vim's default "meaning" of the final result is applied/executed.

"Non-recursive" means the mapping is only expanded once, and that result is applied/executed.

Example:

 nmap K H
 nnoremap H G
 nnoremap G gg

The above causes K to expand to H, then H to expand to G and stop. It stops because of the nnoremap, which expands and stops immediately. The meaning of G will be executed (i.e. "jump to last line"). At most one non-recursive mapping will ever be applied in an expansion chain (it would be the last expansion to happen).

The mapping of G to gg only applies if you press G, but not if you press K. This mapping doesn't affect pressing K regardless of whether G was mapped recursively or not, since it's line 2 that causes the expansion of K to stop, so line 3 wouldn't be used.

For me it was actually a mix of both with Angular 4.4.5.

Using router.navigate kept destroying my url by not respecting the realtiveTo: activatedRoute part.

I've ended up with:

this._location.go(this._router.createUrlTree([this._router.url], { queryParams: { profile: value.id } }).toString())

This worked for me with some css frameworks (material design lite [MDL]).

table {
  table-layout: fixed;
  white-space: normal!important;
}

td {
  word-wrap: break-word;
}

If want to remove the word from only the start of the string, then you could do:

  string[string.startswith(prefix) and len(prefix):]  

Where string is your string variable and prefix is the prefix you want to remove from your string variable.

For example:

  >>> papa = "papa is a good man. papa is the best."  
  >>> prefix = 'papa'
  >>> papa[papa.startswith(prefix) and len(prefix):]
  ' is a good man. papa is the best.'

Looping through all the files in the folder is relatively easy:

files = dir('*.csv');
for file = files'
    csv = load(file.name);
    % Do some stuff
end

I think registering for the UIApplicationWillEnterForegroundNotification is risky as you may end up with more than one controller reacting to that notification. Nothing garanties that these controllers are still visible when the notification is received.

Here is what I do: I force call viewDidAppear on the active controller directly from the App's delegate didBecomeActive method:

Add the code below to - (void)applicationDidBecomeActive:(UIApplication *)application

UIViewController *activeController = window.rootViewController;
if ([activeController isKindOfClass:[UINavigationController class]]) {
    activeController = [(UINavigationController*)window.rootViewController topViewController];
}
[activeController viewDidAppear:NO];

There are VBA methods to zip and unzip using the windows built in compression as well, which should give some insight as to how the system operates. You may be able to build these methods into a scripting language of your choice.

The basic principle is that within windows you can treat a zip file as a directory, and copy into and out of it. So to create a new zip file, you simply make a file with the extension .zip that has the right header for an empty zip file. Then you close it, and tell windows you want to copy files into it as though it were another directory.

Unzipping is easier - just treat it as a directory.

In case the web pages are lost again, here are a few of the relevant code snippets:

You can use different icon for different versions. Simply set logic on your icon like this:

int icon = Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP ? R.drawable.colored_: R.drawable.white_tint_icon_for_lolipop_or_upper;

jcomeau@intrepid:~$ mystring="one two three four five"
jcomeau@intrepid:~$ echo "string length: ${#mystring}"
string length: 23

link Couting characters, words, lenght of the words and total lenght in a sentence

You can also use this:

DF[paste0("stu",c(2,3,5,9)), ]

You can also configure a custom Spring interceptor HandlerInterceptorAdapter for a simplified implementation of pre-only/post-only interceptors:

@Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {

    @Override
    public boolean preHandle (final HttpServletRequest request, final HttpServletResponse response,
            final Object handler)
            throws Exception {

        // Logs here

        return super.preHandle(request, response, handler);
    }

    @Override
    public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
            final Object handler, final Exception ex) {
        // Logs here
    }
}

Then, you register as many interceptors as you want:

@Configuration
public class WebMvcConfig implements WebMvcConfigurer {

    @Autowired
    CustomHttpInterceptor customHttpInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(customHttpInterceptor).addPathPatterns("/endpoints");
    }

}

Note: just like stated by @Robert, you need to pay attention to the specific implementations of HttpServletRequest and HttpServletResponse your application is using.

For example, for apps using the ShallowEtagHeaderFilter, the response implementation would be a ContentCachingResponseWrapper, so you'd have:

@Component
public class CustomHttpInterceptor extends HandlerInterceptorAdapter {

    private static final Logger LOGGER = LoggerFactory.getLogger(CustomHttpInterceptor.class);

    private static final int MAX_PAYLOAD_LENGTH = 1000;

    @Override
    public void afterCompletion(final HttpServletRequest request, final HttpServletResponse response,
            final Object handler, final Exception ex) {
        final byte[] contentAsByteArray = ((ContentCachingResponseWrapper) response).getContentAsByteArray();

        LOGGER.info("Request body:\n" + getContentAsString(contentAsByteArray, response.getCharacterEncoding()));
    }

    private String getContentAsString(byte[] buf, String charsetName) {
        if (buf == null || buf.length == 0) {
            return "";
        }

        try {
            int length = Math.min(buf.length, MAX_PAYLOAD_LENGTH);

            return new String(buf, 0, length, charsetName);
        } catch (UnsupportedEncodingException ex) {
            return "Unsupported Encoding";
        }
    }

}

The first answer is correct but you say that you are using cv2 which inherently uses numpy arrays. So, to make a complete different copy of say "myImage":

newImage = myImage.copy()

The above is enough. No need to import numpy.

Maybe it is really late answer but if you want to navigate another page with param you can,

[routerLink]="['/user', user.id, 'details']"

also you shouldn't forget about routing config like ,

 [path: 'user/:id/details', component:userComponent, pathMatch: 'full']

You need to add reference (System.Web) Reference to System.Web

In Spring boot, /META-INF/resources/, /resources/, static/ and public/ directories are available to serve static contents.

So you can create a static/ or public/ directory under resources/ directory and put your static contents there. And they will be accessible by: http://localhost:8080/your-file.ext. (assuming the server.port is 8080)

You can customize these directories using spring.resources.static-locations in the application.properties.

For example:

spring.resources.static-locations=classpath:/custom/

Now you can use custom/ folder under resources/ to serve static files.

Update:

This is also possible using java config:

@Configuration
public class StaticConfig implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/static/**").addResourceLocations("classpath:/custom/");
    }
}

This confugration maps contents of custom directory to the http://localhost:8080/static/** url.

The port Node is trying to use can be already used by another program. In my case it was ntop, which I had recently installed. I had to open http://localhost:3000/ in a browser to realize it. Another way to find the process is given here.

Basically what I did here is make a page all in one php file where when you enter the password if its right it will hide the password screen and bring the stuff that protected forward. and then heres the css which is a crucial part because it makes the classes that hide and show the different parts of the page.

If you have a UTF-8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the following:

public static string Utf8ToUtf16(string utf8String)
{
    /***************************************************************
     * Every .NET string will store text with the UTF-16 encoding, *
     * known as Encoding.Unicode. Other encodings may exist as     *

     *                                                             *

     *                                                             *

    // Get UTF-8 bytes and remove binary 0 bytes (filler)
    List<byte> utf8Bytes = new List<byte>(utf8String.Length);
    foreach (byte utf8Byte in utf8String)
    {

        if (utf8Byte > 0) {

    }

    // Convert UTF-8 bytes to UTF-16 string
    return Encoding.UTF8.GetString(utf8Bytes.ToArray());
}

In my case the DLL result is a UTF-8 string too, but unfortunately the UTF-8 string is interpreted with UTF-16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 was converted to the UTF-16 '–' which is 8211. If you have this case too, you can use the following instead:

public static string Utf8ToUtf16(string utf8String)
{
    // Get UTF-8 bytes by reading each byte with ANSI encoding
    byte[] utf8Bytes = Encoding.Default.GetBytes(utf8String);

    // Convert UTF-8 bytes to UTF-16 bytes
    byte[] utf16Bytes = Encoding.Convert(Encoding.UTF8, Encoding.Unicode, utf8Bytes);

    // Return UTF-16 bytes as UTF-16 string
    return Encoding.Unicode.GetString(utf16Bytes);
}

Or the Native-Method:

[DllImport("kernel32.dll")]
private static extern Int32 MultiByteToWideChar(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPStr)] String lpMultiByteStr, Int32 cbMultiByte, [Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder lpWideCharStr, Int32 cchWideChar);

public static string Utf8ToUtf16(string utf8String)
{
    Int32 iNewDataLen = MultiByteToWideChar(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf8String, -1, null, 0);
    if (iNewDataLen > 1)
    {
        StringBuilder utf16String = new StringBuilder(iNewDataLen);
        MultiByteToWideChar(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf8String, -1, utf16String, utf16String.Capacity);

        return utf16String.ToString();
    }
    else
    {
        return String.Empty;
    }
}

If you need it the other way around, see Utf16ToUtf8. Hope I could be of help.

Multiline comment in Python:

For me, both ''' and """ worked.

Example:

a = 10
b = 20
c = a+b
'''
print ('hello')
'''
print ('Addition is: ', a+b)

Example:

a = 10
b = 20
c = a+b
"""
print('hello')
"""
print('Addition is: ', a+b)

If someone is looking to sub out more than a comma I'm a fan of:

"1,200".chars.grep(/\d/).join.to_i

dunno about performance but, it is more flexible than a gsub, ie:

"1-200".chars.grep(/\d/).join.to_i

basically i use this in one of our apps: we want to overlay a playicon over a frame of a video:

User helper function:

def if_ok(fn, string):

then

is_number = lambda s: any([if_ok(fn, s) for fn in (int, float, complex)])

It will work on Linux kernel 2.6.28 (confirmed on 4.9.x). It won't work on FreeBSD and other Unix flavors.

Your /usr/local/bin/groovy is a shell script wrapping the Java runtime running Groovy.

See the Interpreter Scripts section of EXECVE(2) and EXECVE(2).

I in no way want to compete with Mark's answer, but just wanted to highlight the piece that finally made everything click as someone new to Javascript inheritance and its prototype chain.

Only property reads search the prototype chain, not writes. So when you set

myObject.prop = '123';

It doesn't look up the chain, but when you set

myObject.myThing.prop = '123';

there's a subtle read going on within that write operation that tries to look up myThing before writing to its prop. So that's why writing to object.properties from the child gets at the parent's objects.

You can do something like this.

Select distinct name from  (SELECT r.name FROM outsider_role_mapping orm1 
    union all
SELECT r.name FROM user_role_mapping orm2
) tmp;

The math library must be linked in when building the executable. How to do this varies by environment, but in Linux/Unix, just add -lm to the command:

gcc test.c -o test -lm

The math library is named libm.so, and the -l command option assumes a lib prefix and .a or .so suffix.

Old question but the remaining answers are outdated as of C++11 - you can use a ranged based for loop and simply do:

std::map<std::string, std::map<std::string, std::string>> mymap;

for(auto const &ent1 : mymap) {
  // ent1.first is the first key
  for(auto const &ent2 : ent1.second) {
    // ent2.first is the second key
    // ent2.second is the data
  }
}

this should be much cleaner than the earlier versions, and avoids unnecessary copies.

Some favour replacing the comments with explicit definitions of reference variables (which get optimised away if unused):

for(auto const &ent1 : mymap) {
  auto const &outer_key = ent1.first;
  auto const &inner_map = ent1.second;
  for(auto const &ent2 : inner_map) {
    auto const &inner_key   = ent2.first;
    auto const &inner_value = ent2.second;
  }
}

When you are creating the router, you can specify the linkExactActiveClass as a property to set the class that will be used for the active router link.

const routes = [
  { path: '/foo', component: Foo },
  { path: '/bar', component: Bar }
]

const router = new VueRouter({
  routes,
  linkActiveClass: "active", // active class for non-exact links.
  linkExactActiveClass: "active" // active class for *exact* links.
})

This is documented here.

This video shows how to update a fork directly from GitHub

Steps:

1. Open your fork on GitHub.
2. Click on Pull Requests.
3. Click on New Pull Request. By default, GitHub will compare the original with your fork, and there shouldn’t be anything to compare if you didn’t make any changes.
4. Click on switching the base. Now GitHub will compare your fork with the original, and you should see all the latest changes.
5. Click on Create a pull request for this comparison and assign a predictable name to your pull request (e.g., Update from original).
6. Click on Create pull request.
7. Scroll down and click Merge pull request and finally Confirm merge. If your fork didn’t have any changes, you will be able to merge it automatically.

Code Runner Extension will only let you "run" java files.

To truly debug 'Java' files follow the quick one-time setup:

• Install Java Debugger Extension in VS Code and reload.
• open an empty folder/project in VS code.
• create your java file (s).
• create a folder .vscode in the same folder.
• create 2 files inside .vscode folder: tasks.json and launch.json
• copy paste below config in tasks.json:

{
    "version": "2.0.0",
    "type": "shell",
    "presentation": {
        "echo": true,
        "reveal": "always",
        "focus": false,
        "panel": "shared"
    },
    "isBackground": true,
    "tasks": [
        {
            "taskName": "build",
            "args": ["-g", "${file}"],
            "command": "javac"
        }
    ]
}

• copy paste below config in launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Java",
            "type": "java",
            "request": "launch",
            "externalConsole": true,                //user input dosen't work if set it to false :(
            "stopOnEntry": true,
            "preLaunchTask": "build",                 // Runs the task created above before running this configuration
            "jdkPath": "${env:JAVA_HOME}/bin",        // You need to set JAVA_HOME enviroment variable
            "cwd": "${workspaceRoot}",
            "startupClass": "${workspaceRoot}${file}",
            "sourcePath": ["${workspaceRoot}"],   // Indicates where your source (.java) files are
            "classpath": ["${workspaceRoot}"],    // Indicates the location of your .class files
            "options": [],                             // Additional options to pass to the java executable
            "args": []                                // Command line arguments to pass to the startup class
        }

    ],
    "compounds": []
}

You are all set to debug java files, open any java file and press F5 (Debug->Start Debugging).

Tip: *To hide .class files in the side explorer of VS code, open settings of VS code and paste the below config:

"files.exclude": {
        "*.class": true
    }

Just got the same problem and I have a relatively simple solution that does not require any change in the page character encoding(wich is a pain in the ass).

For example, your site is in utf-8 and you want to post a form to a site in iso-8859-1. Just change the action of the post to a page on your site that will convert the posted values from utf-8 to iso-8859-1.

this could be done easily in php with something like this:

<?php
$params = array();
foreach($_POST as $key=>$value) {
    $params[] = $key."=".rawurlencode(utf8_decode($value));
}
$params = implode("&",$params);

//then you redirect to the final page in iso-8859-1
?>

You are trying to insert data that is larger than allowed for the column logo.

Use following data types as per your need

TINYBLOB   :     maximum length of 255 bytes  
BLOB       :     maximum length of 65,535 bytes  
MEDIUMBLOB :     maximum length of 16,777,215 bytes  
LONGBLOB   :     maximum length of 4,294,967,295 bytes  

Use LONGBLOB to avoid this exception.

SELECT  *
FROM    trees
WHERE   trees.`title` COLLATE UTF8_GENERAL_CI LIKE '%elm%'

Actually, if you add COLLATE UTF8_GENERAL_CI to your column's definition, you can just omit all these tricks: it will work automatically.

ALTER TABLE trees 
 MODIFY COLUMN title VARCHAR(…) CHARACTER 
 SET UTF8 COLLATE UTF8_GENERAL_CI. 

This will also rebuild any indexes on this column so that they could be used for the queries without leading '%'

Maybe is configuration issue

nano /etc/zabbix/zabbix_server.conf

DBHost=localhost

DBName=zabbix_db

DBUser=zabbix_user

I found these two links very helpful while I was trying to learn socket.io:

Use curl to fetch the HTTP-header only (not the whole file) and parse it:

$ curl -I  --stderr /dev/null http://www.google.co.uk/index.html | head -1 | cut -d' ' -f2

As DotNetMensch said but you DO NOT need to add another site in IIS as this can also cause further problems and make things more complicated because you then have a website within a website so the file paths, masterpage paths and web.config paths may need changing. You just need to edit teh bindings of the existing site and add the new subdomain there.

So:

1. Add sub-domain to DNS records. My host (RackSpace) uses a web portal to do this so you just log in and go to Network->Domains(DNS)->Actions->Create Zone, and enter your subdomain as mysubdomain.domain.com etc, leave the other settings as default

2. Go to your domain in IIS, right-click->Edit Bindings->Add, and add your new subdomain leaving everything else the same e.g. mysubdomain.domain.com

You may need to wait 5-10 mins for the DNS records to update but that's all you need.

Since creating an JQuery object for every comparison is not efficient, just use:

$.expr[":"].blank = function(element) {
    return element.value == "";
};

Then you can do:

$(":input:blank")

When you save your file, make sure it has the extension .java. If it does not, Eclipse won't know to read it as a java file.

SELECT EXTRACT( YEAR_MONTH FROM `date` ) 
FROM `Table` WHERE Condition = 'Condition';

Here is a non-jquery way to monitor events in the console with your code and without the use of monitorEvents() because that only works in Chrome Developer Console. You can also choose to not monitor certain events by editing the no_watch array.

    function getEvents(obj) {
    window["events_list"] = [];
    var no_watch = ['mouse', 'pointer']; // Array of event types not to watch
    var no_watch_reg = new RegExp(no_watch.join("|"));

    for (var prop in obj) {
        if (prop.indexOf("on") === 0) {
            prop = prop.substring(2); // remove "on" from beginning
            if (!prop.match(no_watch_reg)) {
                window["events_list"].push(prop);
                window.addEventListener(prop, function() {
                    console.log(this.event); // Display fired event in console
                } , false);
            }
        }
    }
    window["events_list"].sort(); // Alphabetical order 

}

getEvents(document); // Put window, document or any html element here
console.log(events_list); // List every event on element

/* Adding the script tag to the head as suggested before */

    var head = document.getElementsByTagName('head')[0];
    var script = document.createElement('script');
    script.type = 'text/javascript';
    script.src = "http://code.jquery.com/jquery-2.2.1.min.js";

    // Then bind the event to the callback function.
    // There are several events for cross browser compatibility.
    script.onreadystatechange = handler;
    script.onload = handler;

    // Fire the loading
    head.appendChild(script);

    function handler(){
       console.log('jquery added :)');
    }

I was able to find a simple way to achieve both scrolling behaviors.

Here is the xml for it:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:scrollbars="vertical">

    <HorizontalScrollView 
        android:layout_width="320px" android:layout_height="fill_parent">

        <TableLayout
            android:id="@+id/linlay" android:layout_width="320px"
            android:layout_height="fill_parent" android:stretchColumns="1"
            android:background="#000000"/>

    </HorizontalScrollView>

</ScrollView>

In the latest IntelliJ IDEA version (2020.1.3 Ultimate Edition), You need to to click this little guy that appears on the top right of the editor window after you make a change to the pom.xml

This little guy is too small and in an unnoticeable position. I liked the previous versions where an alert shows up in the bottom right. Still can't find the option to enable auto import in this version.

Note that Python classes are also callable.

To get functions (and by functions we mean standard functions and lambdas) use:

import types

def is_func(obj):
    return isinstance(obj, (types.FunctionType, types.LambdaType))


def f(x):
    return x


assert is_func(f)
assert is_func(lambda x: x)

If you have a nested dictionary, and you want this to work even for empty sub-elements, you can use a recursive variant of BrenBarn's suggestion:

def scrub_dict(d):
    if type(d) is dict:
        return dict((k, scrub_dict(v)) for k, v in d.iteritems() if v and scrub_dict(v))
    else:
        return d

To fix this issue I made sure my body height was set to 100%.

body { height:100% }

This also maintains the center position while the user scrolls.

From XML.com:

Like xsl:if instructions, xsl:when elements can have more elaborate contents between their start- and end-tags—for example, literal result elements, xsl:element elements, or even xsl:if and xsl:choose elements—to add to the result tree. Their test expressions can also use all the tricks and operators that the xsl:if element's test attribute can use, such as and, or, and function calls, to build more complex boolean expressions.

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

Strong entity

It can exist without any other entity.

Example

Customer(customerid, name, surname)

Weak entity

It depends on a dominant entity, and it cannot exist without a strong entity.

Example

Adress(addressid, adressName, customerid)

Drop the public $bar; declaration and it should work as expected.

1. html_safe :

   Marks a string as trusted safe. It will be inserted into HTML with no additional escaping performed.

   "<a>Hello</a>".html_safe
   #=> "<a>Hello</a>"
   
   nil.html_safe
   #=> NoMethodError: undefined method `html_safe' for nil:NilClass
   

2. raw :

   raw is just a wrapper around html_safe. Use raw if there are chances that the string will be nil.

   raw("<a>Hello</a>")
   #=> "<a>Hello</a>"
   
   raw(nil)
   #=> ""
   

3. h alias for html_escape :

   A utility method for escaping HTML tag characters. Use this method to escape any unsafe content.

   In Rails 3 and above it is used by default so you don't need to use this method explicitly

I want to add something on @Michael Laffargue's post:

jqXHR.done() is faster!

jqXHR.success() have some load time in callback and sometimes can overkill script. I find that on hard way before.

UPDATE:

Using jqXHR.done(), jqXHR.fail() and jqXHR.always() you can better manipulate with ajax request. Generaly you can define ajax in some variable or object and use that variable or object in any part of your code and get data faster. Good example:

/* Initialize some your AJAX function */
function call_ajax(attr){
    var settings=$.extend({
        call            : 'users',
        option          : 'list'
    }, attr );

    return $.ajax({
        type: "POST",
        url: "//exapmple.com//ajax.php",
        data: settings,
        cache : false
    });
}

/* .... Somewhere in your code ..... */

call_ajax({
    /* ... */
    id : 10,
    option : 'edit_user'
    change : {
          name : 'John Doe'
    }
    /* ... */
}).done(function(data){

    /* DO SOMETHING AWESOME */

});

From Object Explorer in SQL Server Management Studio, find your database and expand the node (click on the + sign beside your database). The first item from that expanded tree is Database Diagrams. Right-click on that and you'll see various tasks including creating a new database diagram. If you've never created one before, it'll ask if you want to install the components for creating diagrams. Click yes then proceed.

Your 0xED 0x6E 0x2C 0x20 bytes correspond to "ín, " in ISO-8859-1, so it looks like your content is in ISO-8859-1, not UTF-8. Tell your data provider about it and ask them to fix it, because if it doesn't work for you it probably doesn't work for other people either.

Now there are a few ways to work it around, which you should only use if you cannot load the XML normally. One of them would be to use utf8_encode(). The downside is that if that XML contains both valid UTF-8 and some ISO-8859-1 then the result will contain mojibake. Or you can try to convert the string from UTF-8 to UTF-8 using iconv() or mbstring, and hope they'll fix it for you. (they won't, but you can at least ignore the invalid characters so you can load your XML)

Or you can take the long, long road and validate/fix the sequences by yourself. That will take you a while depending on how familiar you are with UTF-8. Perhaps there are libraries out there that would do that, although I don't know any.

Either way, notify your data provider that they're sending invalid data so that they can fix it.

Here's a partial fix. It will definitely not fix everything, but will fix some of it. Hopefully enough for you to get by until your provider fix their stuff.

function fix_latin1_mangled_with_utf8_maybe_hopefully_most_of_the_time($str)
{
    return preg_replace_callback('#[\\xA1-\\xFF](?![\\x80-\\xBF]{2,})#', 'utf8_encode_callback', $str);
}

function utf8_encode_callback($m)
{
    return utf8_encode($m[0]);
}

Short answer

mvn install

• adds all artifact (dependencies) specified in pom, to the local repository (from remote sources).

you definitively want a List:

The List interface provides four methods for positional (indexed) access to list elements. Lists (like Java arrays) are zero based.

Also

Note that these operations may execute in time proportional to the index value for some implementations (the LinkedList class, for example). Thus, iterating over the elements in a > list is typically preferable to indexing through it if the caller does not know the implementation.

If you need the index in order to modify your collection you should note that List provides a special ListIterator that allow you to get the index:

List<String> names = Arrays.asList("Davide", "Francesco", "Angelocola");
ListIterator<String> i = names.listIterator();

while (i.hasNext()) {
    System.out.format("[%d] %s\n", i.nextIndex(), i.next());
}

Nothing as useful as this: Common Data Structure Operations:

If you talk about Activity, AppcompactActivity, ActionBarActivity etc etc..

We need to talk about Base classes which they are extending, First we have to understand the hierarchy of super classes.

All the things are started from Context which is super class for all these classes.

Context is an abstract class whose implementation is provided by the Android system. It allows access to application-specific resources and classes, as well as up-calls for application-level operations such as launching activities, broadcasting and receiving intents, etc

Context is followed by or extended by ContextWrapper

The ContextWrapper is a class which extend Context class that simply delegates all of its calls to another Context. Can be subclassed to modify behavior without changing the original Context.

Now we Reach to Activity

The Activity is a class which extends ContextThemeWrapper that is a single, focused thing that the user can do. Almost all activities interact with the user, so the Activity class takes care of creating a window for you

Below Classes are restricted to extend but they are extended by their descender internally and provide support for specific Api

The SupportActivity is a class which extends Activity that is a Base class for composing together compatibility functionality

The BaseFragmentActivityApi14 is a class which extends SupportActivity that is a Base class It is restricted class but it is extend by BaseFragmentActivityApi16 to support the functionality of V14

The BaseFragmentActivityApi16 is a class which extends BaseFragmentActivityApi14 that is a Base class for {@code FragmentActivity} to be able to use v16 APIs. But it is also restricted class but it is extend by FragmentActivity to support the functionality of V16.

now FragmentActivty

The FragmentActivity is a class which extends BaseFragmentActivityApi16 and that wants to use the support-based Fragment and Loader APIs.

When using this class as opposed to new platform's built-in fragment and loader support, you must use the getSupportFragmentManager() and getSupportLoaderManager() methods respectively to access those features.

ActionBarActivity is part of the Support Library. Support libraries are used to deliver newer features on older platforms. For example the ActionBar was introduced in API 11 and is part of the Activity by default (depending on the theme actually). In contrast there is no ActionBar on the older platforms. So the support library adds a child class of Activity (ActionBarActivity) that provides the ActionBar's functionality and ui

In 2015 ActionBarActivity is deprecated in revision 22.1.0 of the Support Library. AppCompatActivity should be used instead.

The AppcompactActivity is a class which extends FragmentActivity that is Base class for activities that use the support library action bar features.

You can add an ActionBar to your activity when running on API level 7 or higher by extending this class for your activity and setting the activity theme to Theme.AppCompat or a similar theme

I refer these two one,two

How will the browser know when to run the code inside script tag? So, to make the code run after the window is loaded completely,

window.onload = doStuff;

function doStuff() {
    var e = document.getElementById("db_info");
    e.innerHTML='Found you';
}

The other alternative is to keep your <script...</script> just before the closing </body> tag.

well, this using lodash or vanilla javascript it depends on the situation.

but for just return the array that contains the duplicates it can be achieved by the following, offcourse it was taken from @1983

var result = result1.filter(function (o1) {
    return result2.some(function (o2) {
        return o1.id === o2.id; // return the ones with equal id
   });
});
// if you want to be more clever...
let result = result1.filter(o1 => result2.some(o2 => o1.id === o2.id));

I tried so many solutions on here that didn't work for me, only displaying some of the ports. But the following displayed All of them and their information.

        using (var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_PnPEntity WHERE Caption like '%(COM%'"))
        {
            var portnames = SerialPort.GetPortNames();
            var ports = searcher.Get().Cast<ManagementBaseObject>().ToList().Select(p => p["Caption"].ToString());

            var portList = portnames.Select(n => n + " - " + ports.FirstOrDefault(s => s.Contains(n))).ToList();

            foreach(string s in portList)
            {
                Console.WriteLine(s);
            }
        }
    }

I had this same issue but my resolution was different because this didn't completely work.

I found this on a GitHub forum - copy and paste this into your terminal. You don't have to change your password; it can be the exact same.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;
ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '{NewPassword}';

I had the same problem too. I used this code:

Intent photoPickerIntent = new Intent(Intent.ACTION_GET_CONTENT);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);

Using the ADM, add the images on the sdcard or anywhere.

And when you are in your vm and the selection screen shows up, browse using the top left dropdown seen in the image below.

If you prefer using method (lambda) syntax as I do, you could do the same thing like this:

var result = new TableName();

using(var db = new EFObjectContext)
{
    var query = db.TableName;

    query = value1 == null 
        ? query.Where(tbl => tbl.entry1 == null) 
        : query.Where(tbl => tbl.entry1 == value1);

    query = value2 == null 
        ? query.Where(tbl => tbl.entry2 == null) 
        : query.Where(tbl => tbl.entry2 == value2);

    result = query
        .Select(tbl => tbl)
        .FirstOrDefault();

   // Inspect the value of the trace variable below to see the sql generated by EF
   var trace = ((ObjectQuery<REF_EQUIPMENT>) query).ToTraceString();

}

return result;

With JUnit 5.4, you can specify the order :

@Test
@Order(2)
public void sendEmailTestGmail() throws MessagingException {

you just need to annotate your class

@TestMethodOrder(OrderAnnotation.class)

i'm using this in my project and it works very well !

Specifically if you want to clear your text box in VB.NET or VB 6.0, write this code:

TextBox1.Items.Clear()

If you are using VBA, then the use this code :

TextBox1.Text = "" or TextBox1.Clear()

If you are using react you can use the as operator.

let inputValue = (document.getElementById(elementId) as HTMLInputElement).value;

These are the breaking changes from Python 3.x and Python 2.x

For Python3.x use

dictlist = []
for key, value in dict.items():
    temp = [key,value]
    dictlist.append(temp)

For Python 2.7 use

dictlist = []
for key, value in dict.iteritems():
    temp = [key,value]
    dictlist.append(temp)

So, it turns out that X11 wasn't actually installed on the centOS. There didn't seem to be any indication anywhere of it not being installed. I did the following command and now firefox opens:

yum groupinstall 'X Window System' 

Hope this answer will help others that are confused :)

In my case one unmanaged dll was depending on another which was missing. In that case the error will point to the existing dll instead of the missing one which can be really confusing.

That is exactly what had happen in my case. Hope this helps someone else.

The stream editor does modify multiple files “inplace” when invoked with the -i switch, which takes a backup file ending as argument. So

sed -i.bak 's/foo/bar/g' *

replaces foo with bar in all files in this folder, but does not descend into subfolders. This will however generate a new .bak file for every file in your directory. To do this recursively for all files in this directory and all its subdirectories, you need a helper, like find, to traverse the directory tree.

find ./ -print0 | xargs -0 sed -i.bak 's/foo/bar/g' *

find allows you further restrictions on what files to modify, by specifying further arguments like find ./ -name '*.php' -or -name '*.html' -print0, if necessary.

Note: GNU sed does not require a file ending, sed -i 's/foo/bar/g' * will work, as well; FreeBSD sed demands an extension, but allows a space in between, so sed -i .bak s/foo/bar/g * works.

If you don't need the DATETIME value in the rest of your code, it'd be more efficient, simple and secure to use an UPDATE query with a sub-select, something like

UPDATE products SET t=(SELECT f FROM products WHERE id=17) WHERE id=42;

or in case it's in the same row in a single table, just

UPDATE products SET t=f WHERE id=42;

It's downloaded probably because there is not Adobe Reader plug-in installed. In this case, IE (it doesn't matter which version) doesn't know how to render it, and it'll simply download the file (Chrome, for example, has its own embedded PDF renderer).

That said. <iframe> is not best way to display a PDF (do not forget compatibility with mobile browsers, for example Safari). Some browsers will always open that file inside an external application (or in another browser window). Best and most compatible way I found is a little bit tricky but works on all browsers I tried (even pretty outdated):

Keep your <iframe> but do not display a PDF inside it, it'll be filled with an HTML page that consists of an <object> tag. Create an HTML wrapping page for your PDF, it should look like this:

<html>
<body>
    <object data="your_url_to_pdf" type="application/pdf">
        <embed src="your_url_to_pdf" type="application/pdf" />
    </object>
</body>
</html>

Of course, you still need the appropriate plug-in installed in the browser. Also, look at this post if you need to support Safari on mobile devices.

1st. Why nesting <embed> inside <object>? You'll find the answer here on SO. Instead of a nested <embed> tag, you may (should!) provide a custom message for your users (or a built-in viewer, see next paragraph). Nowadays, <object> can be used without worries, and <embed> is useless.

2nd. Why an HTML page? So you can provide a fallback if PDF viewer isn't supported. Internal viewer, plain HTML error messages/options, and so on...

It's tricky to check PDF support so that you may provide an alternate viewer for your customers, take a look at PDF.JS project; it's pretty good but rendering quality - for desktop browsers - isn't as good as a native PDF renderer (I didn't see any difference in mobile browsers because of screen size, I suppose).

Yes! You can use the new Visual Studio for Mac, which Microsoft launched in November.

return; // Prematurely return from the method (same keword works in VB, by the way)

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

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

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

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

      Console.Read();
    }

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

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

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

      collection.Dispose();
      return devices;
    }
  }

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

I would first check if your implementation supports isArray:

if (Array.isArray)
    return Array.isArray(v);

You could also try using the instanceof operator

v instanceof Array

Setting overflow: hidden hides the scrollbar. Set overflow: scroll to make sure the scrollbar appears all the time.

To use the ::webkit-scrollbar property, simply target .scroll before calling it.

.scroll {
   width: 200px;
   height: 400px;
    background: red;
   overflow: scroll;
}
.scroll::-webkit-scrollbar {
    width: 12px;
}

.scroll::-webkit-scrollbar-track {
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.3); 
    border-radius: 10px;
}

.scroll::-webkit-scrollbar-thumb {
    border-radius: 10px;
    -webkit-box-shadow: inset 0 0 6px rgba(0,0,0,0.5); 
}
?

See this live example

This function is used to clear all the elements in the form including radio button, check-box, select, multiple select, password, text, textarea, file.

function clear_form_elements(class_name) {
  jQuery("."+class_name).find(':input').each(function() {
    switch(this.type) {
        case 'password':
        case 'text':
        case 'textarea':
        case 'file':
        case 'select-one':
        case 'select-multiple':
        case 'date':
        case 'number':
        case 'tel':
        case 'email':
            jQuery(this).val('');
            break;
        case 'checkbox':
        case 'radio':
            this.checked = false;
            break;
    }
  });
}

This is a solution suggested by the MySQl manual:

If expr is given as an argument to LAST_INSERT_ID(), the value of the argument is returned by the function and is remembered as the next value to be returned by LAST_INSERT_ID(). This can be used to simulate sequences:

Create a table to hold the sequence counter and initialize it:

    mysql> CREATE TABLE sequence (id INT NOT NULL);
    mysql> INSERT INTO sequence VALUES (0);

Use the table to generate sequence numbers like this:

    mysql> UPDATE sequence SET id=LAST_INSERT_ID(id+1);
    mysql> SELECT LAST_INSERT_ID();

The UPDATE statement increments the sequence counter and causes the next call to LAST_INSERT_ID() to return the updated value. The SELECT statement retrieves that value. The mysql_insert_id() C API function can also be used to get the value. See Section 23.8.7.37, “mysql_insert_id()”.

You can generate sequences without calling LAST_INSERT_ID(), but the utility of using the function this way is that the ID value is maintained in the server as the last automatically generated value. It is multi-user safe because multiple clients can issue the UPDATE statement and get their own sequence value with the SELECT statement (or mysql_insert_id()), without affecting or being affected by other clients that generate their own sequence values.

You can also use:

$('#test').context.scrollHeight

Even easier:

for c in "test":
    print c

First, you have to create two animation resources in res/anim dir

slide_up.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromYDelta="100%"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toXDelta="0">
</translate>
</set>

slide_bottom.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate 
    android:duration="@android:integer/config_mediumAnimTime" 
    android:fromYDelta="0%p" 
    android:interpolator="@android:anim/accelerate_interpolator" 
    android:toYDelta="100%p">
</translate>
</set>

then you have to create a style

<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_up</item>
    <item name="android:windowExitAnimation">@anim/slide_bottom</item>
</style>

and add this line to your class

dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation; //style id

Based in http://www.devexchanges.info/2015/10/showing-dialog-with-animation-in-android.html

Visio Professional has a database reverse-engineering feature if yiu create a database diagram. It's not free but is fairly ubiquitous in most companies and should be fairly easy to get.

Note that Visio 2003 does not play nicely with SQL2005 or SQL2008 for reverse engineering - you will need to get 2007.

In this particular case, due to the dangers cited in other answers, I would

1. Edit in e.g. Vim and :%s/\s/\\\0/g, escaping all space characters with a backslash.

2. Then :%s/^/rm -rf /, prepending the command. With -r you don't have to worry to have directories listed after the files contained therein, and with -f it won't complain due to missing files or duplicate entries.

3. Run all the commands: $ source 1.txt

USING POD

<?php
$username = "root";
$password = "";
$db = "db_name";

$dns = "mysql:host=localhost;dbname=$db;charset=utf8mb4";
    $conn = new PDO($dns,$username, $password);
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $sql = "select * from mine where username = ? ";

    $stmt1 = $conn->prepare($sql);
    $stmt1 -> execute(array($_POST['user']));
    $all = $stmt1->fetchAll(); ?>

    <div class="controls">
        <select  data-rel="chosen"  name="degree_id" id="selectError">

                 <?php foreach($all as $nt) { echo "<option value =$nt[id]>$nt[name]</option>";}?>
        </select>

    </div>

In dead simple way it makes this meaning.

Functions :

These subprograms return a single value; mainly used to compute and return a value.

Procedure :

These subprograms do not return a value directly; mainly used to perform an action.

Example Program:

CREATE OR REPLACE PROCEDURE greetings

BEGIN 

dbms_output.put_line('Hello World!');

END ;
/

Executing a Standalone Procedure :

A standalone procedure can be called in two ways:

• Using the EXECUTE keyword • Calling the name of procedure from a PL/SQL block

The procedure can also be called from another PL/SQL block:

BEGIN 
greetings;
END;
/

Function:

CREATE OR REPLACE FUNCTION totalEmployees 
RETURN number IS
total number(3) := 0;
BEGIN 
SELECT count(*) into total 
FROM employees;
RETURN total; 
END;
/

Following program calls the function totalCustomers from an another block

DECLARE 
c number(3);
BEGIN 
c := totalEmployees();
dbms_output.put_line('Total no. of Employees: ' || c);
END;
/

Best thing to use is HTMLAgilityPack. You can also look into using Fizzler or CSQuery depending on your needs for selecting the elements from the retrieved page. Using LINQ or Regukar Expressions is just to error prone, especially when the HTML can be malformed, missing closing tags, have nested child elements etc.

You need to stream the page into an HtmlDocument object and then select your required element.

// Call the page and get the generated HTML
var doc = new HtmlAgilityPack.HtmlDocument();
HtmlAgilityPack.HtmlNode.ElementsFlags["br"] = HtmlAgilityPack.HtmlElementFlag.Empty;
doc.OptionWriteEmptyNodes = true;

try
{
    var webRequest = HttpWebRequest.Create(pageUrl);
    Stream stream = webRequest.GetResponse().GetResponseStream();
    doc.Load(stream);
    stream.Close();
}
catch (System.UriFormatException uex)
{
    Log.Fatal("There was an error in the format of the url: " + itemUrl, uex);
    throw;
}
catch (System.Net.WebException wex)
{
    Log.Fatal("There was an error connecting to the url: " + itemUrl, wex);
    throw;
}

//get the div by id and then get the inner text 
string testDivSelector = "//div[@id='test']";
var divString = doc.DocumentNode.SelectSingleNode(testDivSelector).InnerHtml.ToString();

[EDIT] Actually, scrap that. The simplest method is to use FizzlerEx, an updated jQuery/CSS3-selectors implementation of the original Fizzler project.

Code sample directly from their site:

using HtmlAgilityPack;
using Fizzler.Systems.HtmlAgilityPack;

//get the page
var web = new HtmlWeb();
var document = web.Load("http://example.com/page.html");
var page = document.DocumentNode;

//loop through all div tags with item css class
foreach(var item in page.QuerySelectorAll("div.item"))
{
    var title = item.QuerySelector("h3:not(.share)").InnerText;
    var date = DateTime.Parse(item.QuerySelector("span:eq(2)").InnerText);
    var description = item.QuerySelector("span:has(b)").InnerHtml;
}

I don't think it can get any simpler than that.

Everything in /var/lib/docker are filesystems of containers. If you stop all your containers and prune them, you should end up with the folder being empty. You probably don't really want that, so don't go randomly deleting stuff in there. Do not delete things in /var/lib/docker directly. You may get away with it sometimes, but it's inadvisable for so many reasons.

Do this instead:

sudo bash
cd /var/lib/docker
find . -type f | xargs du -b  | sort -n

What you will see is the largest files shown at the bottom. If you want, figure out what containers those files are in, enter those containers with docker exec -ti containername -- /bin/sh and delete some files.

You can also put docker system prune -a -f on a daily/weekly cron job as long as you aren't leaving stopped containers and volumes around that you care about. It's better to figure out the reasons why it's growing, and correct them at the container level.

the easiest way to avoid slow retrieval of the remote WSDL when you instantiate your SEI is to not retrieve the WSDL from the remote service endpoint at runtime.

this means that you have to update your local WSDL copy any time the service provider makes an impacting change, but it also means that you have to update your local copy any time the service provider makes an impacting change.

When I generate my client stubs, I tell the JAX-WS runtime to annotate the SEI in such a way that it will read the WSDL from a pre-determined location on the classpath. by default the location is relative to the package location of the Service SEI

<wsimport
    sourcedestdir="${dao.helter.dir}/build/generated"
    destdir="${dao.helter.dir}/build/bin/generated"
    wsdl="${dao.helter.dir}/src/resources/schema/helter/helterHttpServices.wsdl"
    wsdlLocation="./wsdl/helterHttpServices.wsdl"
    package="com.helter.esp.dao.helter.jaxws"
    >
    <binding dir="${dao.helter.dir}/src/resources/schema/helter" includes="*.xsd"/>
</wsimport>
<copy todir="${dao.helter.dir}/build/bin/generated/com/helter/esp/dao/helter/jaxws/wsdl">
    <fileset dir="${dao.helter.dir}/src/resources/schema/helter" includes="*" />
</copy>

the wsldLocation attribute tells the SEI where is can find the WSDL, and the copy makes sure that the wsdl (and supporting xsd.. etc..) is in the correct location.

since the location is relative to the SEI's package location, we create a new sub-package (directory) called wsdl, and copy all the wsdl artifacts there.

all you have to do at this point is make sure you include all *.wsdl, *.xsd in addition to all *.class when you create your client-stub artifact jar file.

(in case your curious, the @webserviceClient annotation is where this wsdl location is actually set in the java code

@WebServiceClient(name = "httpServices", targetNamespace = "http://www.helter.com/schema/helter/httpServices", wsdlLocation = "./wsdl/helterHttpServices.wsdl")

As per commented by @Prescott, the opposite of:

evt.preventDefault();

Could be:

Essentially equating to 'do default', since we're no longer preventing it.

Otherwise I'm inclined to point you to the answers provided by another comments and answers:

How to unbind a listener that is calling event.preventDefault() (using jQuery)?

How to reenable event.preventDefault?

Note that the second one has been accepted with an example solution, given by redsquare (posted here for a direct solution in case this isn't closed as duplicate):

$('form').submit( function(ev) {
     ev.preventDefault();
     //later you decide you want to submit
     $(this).unbind('submit').submit()
});

A simulation is a system that behaves similar to something else, but is implemented in an entirely different way. It provides the basic behavior of a system but may not necessarily abide by all of the rules of the system being simulated. It is there to give you an idea about how something works.

An emulation is a system that behaves exactly like something else, and abides by all of the rules of the system being emulated. It is effectively a complete replication of another system, right down to being binary compatible with the emulated system's inputs and outputs, but operating in a different environment to the environment of the original emulated system. The rules are fixed, and cannot be changed or the system fails.

The best answer according to the Python programming FAQ would be:

functions = {'myfoo': foo.bar}

mystring = 'myfoo'
if mystring in functions:
    functions[mystring]()

The primary advantage of this technique is that the strings do not need to match the names of the functions. This is also the primary technique used to emulate a case construct

       if(props.userType){
          var data = []
          Object.keys(props.userType).map(i=>{
                data.push(props.userType[i])
          })
          setService(data)
        }

This trick works for me. Hope this could help you. Let's save the followings as checkRunningProcess.sh

#!/bin/bash
ps_out=`ps -ef | grep $1 | grep -v 'grep' | grep -v $0`
result=$(echo $ps_out | grep "$1")
if [[ "$result" != "" ]];then
    echo "Running"
else
    echo "Not Running"
fi

Make the checkRunningProcess.sh executable.And then use it.
Example to use.

20:10 $ checkRunningProcess.sh proxy.py
Running
20:12 $ checkRunningProcess.sh abcdef
Not Running

Print a string as hex bytes?

The accepted answer gives:

s = "Hello world !!"
":".join("{:02x}".format(ord(c)) for c in s)

returns:

'48:65:6c:6c:6f:20:77:6f:72:6c:64:20:21:21'

The accepted answer works only so long as you use bytes (mostly ascii characters). But if you use unicode, e.g.:

a_string = u"?????? ???!!" # "Prevyet mir", or "Hello World" in Russian.

You need to convert to bytes somehow.

If your terminal doesn't accept these characters, you can decode from UTF-8 or use the names (so you can paste and run the code along with me):

a_string = (
    "\N{CYRILLIC CAPITAL LETTER PE}"
    "\N{CYRILLIC SMALL LETTER ER}"
    "\N{CYRILLIC SMALL LETTER I}"
    "\N{CYRILLIC SMALL LETTER VE}"
    "\N{CYRILLIC SMALL LETTER IE}"
    "\N{CYRILLIC SMALL LETTER TE}"
    "\N{SPACE}"
    "\N{CYRILLIC SMALL LETTER EM}"
    "\N{CYRILLIC SMALL LETTER I}"
    "\N{CYRILLIC SMALL LETTER ER}"
    "\N{EXCLAMATION MARK}"
    "\N{EXCLAMATION MARK}"
)

So we see that:

":".join("{:02x}".format(ord(c)) for c in a_string)

returns

'41f:440:438:432:435:442:20:43c:438:440:21:21'

a poor/unexpected result - these are the code points that combine to make the graphemes we see in Unicode, from the Unicode Consortium - representing languages all over the world. This is not how we actually store this information so it can be interpreted by other sources, though.

To allow another source to use this data, we would usually need to convert to UTF-8 encoding, for example, to save this string in bytes to disk or to publish to html. So we need that encoding to convert the code points to the code units of UTF-8 - in Python 3, ord is not needed because bytes are iterables of integers:

>>> ":".join("{:02x}".format(c) for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

Or perhaps more elegantly, using the new f-strings (only available in Python 3):

>>> ":".join(f'{c:02x}' for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

In Python 2, pass c to ord first, i.e. ord(c) - more examples:

>>> ":".join("{:02x}".format(ord(c)) for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'
>>> ":".join(format(ord(c), '02x') for c in a_string.encode('utf-8'))
'd0:9f:d1:80:d0:b8:d0:b2:d0:b5:d1:82:20:d0:bc:d0:b8:d1:80:21:21'

just enter the following command on command prompt after launching the app:

adb shell dumpsys window windows | find "mCurrentFocus"

if executing the command on linux terminal replace find by grep

Hope this will work for you!

You can use library(qpcR) for combining two matrix with unequal size.

resultant_matrix <- qpcR:::cbind.na(matrix1, matrix2)

NOTE:- The resultant matrix will be of size of matrix2.

    public int MinimumValue { get; private set; }
    public int MaxmimumValue { get; private set; }

    public void num()
    {
        int[] array = { 12, 56, 89, 65, 61, 36, 45, 23 };
        MaxmimumValue = array[0];
        MinimumValue = array[0];

        foreach (int num in array)

        {

            if (num > MaxmimumValue) MaxmimumValue = num;
            if (num < MinimumValue) MinimumValue = num;
        }
        Console.WriteLine(MinimumValue);
        Console.WriteLine(MaxmimumValue);
    }

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

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

So your code should actually be written like this:

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

    End If
    Obj.DataBind()
End Sub

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

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

End If

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

I had the same error and I had not made any changes to the application config or the web.xml. Multiple tries to revert back some minor changes to code was not clearing the exceptions. Finally it worked after restarting STS.

You may have to first update all the records that are null to the default value then use the alter table statement.

where Created is NULL

new Date(Date.now() + (-1*new Date().getTimezoneOffset()*60000)).toISOString()

'parent.relativePath' points at wrong local POM @ myGroup:myParentArtifactId:1.0, C:\myProjectDir\parent\pom.xml

This indicates that maven did search locally for the parent pom, but found that it was not the correct pom.

• Does pom.xml of parentpom correctly define the parent pom as the pom.xml of rootpom?
• Does rootpom folder contain pom.xml as well as the paretpom folder?

You mean the tellItLikeItIs method? Yes, you have to specify void to specify that the method doesn't return anything. All methods have to have a return type specified, even if it's void.

It certainly doesn't return a string - look, there are no return statements anywhere. It's not really clear why you think it is returning a string. It's printing strings to the console, but that's not the same thing as returning one from the method.

TL;DR

git reset resets Staging to the last commit. Use --hard to also reset files in your Working directory to the last commit.

LONGER VERSION

But that's obviously simplistic hence the many rather verbose answers. It made more sense for me to read up on git reset in the context of undoing changes. E.g. see this:

If git revert is a “safe” way to undo changes, you can think of git reset as the dangerous method. When you undo with git reset(and the commits are no longer referenced by any ref or the reflog), there is no way to retrieve the original copy—it is a permanent undo. Care must be taken when using this tool, as it’s one of the only Git commands that has the potential to lose your work.

From https://www.atlassian.com/git/tutorials/undoing-changes/git-reset

and this

On the commit-level, resetting is a way to move the tip of a branch to a different commit. This can be used to remove commits from the current branch.

I think ImageFont module available in PIL should be helpful in solving text font size problem. Just check what font type and size is appropriate for you and use following function to change font values.

# font = ImageFont.truetype(<font-file>, <font-size>)
# font-file should be present in provided path.
font = ImageFont.truetype("sans-serif.ttf", 16)

So your code will look something similar to:

from PIL import Image
from PIL import ImageFont
from PIL import ImageDraw 

img = Image.open("sample_in.jpg")
draw = ImageDraw.Draw(img)
# font = ImageFont.truetype(<font-file>, <font-size>)
font = ImageFont.truetype("sans-serif.ttf", 16)
# draw.text((x, y),"Sample Text",(r,g,b))
draw.text((0, 0),"Sample Text",(255,255,255),font=font)
img.save('sample-out.jpg')

You might need to put some extra effort to calculate font size. In case you want to change it based on amount of text user has provided in TextArea.

To add text wrapping (Multiline thing) just take a rough idea of how many characters can come in one line, Then you can probably write a pre-pprocessing function for your Text, Which basically finds the character which will be last in each line and converts white space before this character to new-line.

First of all, the place in your code where you are initializing (i.e. assigning for the first time) foo is here:

foo = new ArrayList();

foo is an object (with type List) so it is a reference type, not a value type (like int). As such, it holds a reference to a memory location (e.g. 0xA7D2A834) where your List elements are stored. Lines like this

foo.add("foo"); // Modification-1

do not change the value of foo (which, again, is just a reference to a memory location). Instead, they just add elements into that referenced memory location. To violate the final keyword, you would have to try to re-assign foo as follows again:

foo = new ArrayList();

That would give you a compilation error.

Now, with that out of the way, think about what happens when you add the static keyword.

When you do NOT have the static keyword, each object that instantiates the class has its own copy of foo. Therefore, the constructor assigns a value to a blank, fresh copy of the foo variable, which is perfectly fine.

However, when you DO have the static keyword, only one foo exists in memory that is associated with the class. If you were to create two or more objects, the constructor would be attempting to re-assign that one foo each time, violating the final keyword.

In my case setting AppPool->AdvancedSettings->Maximum Worker Proccesses to 1 helped.

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:

NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")

I've been in the need for this feature many times, therefore I've extracted it into a mixin. It can be used like this:

import windowScrollPosition from 'path/to/mixin.js'

new Vue({
  mixins: [ windowScrollPosition('position') ]
})

This creates a reactive position property (can be named whatever we like) on the Vue instance. The property contains the window scroll position as an [x,y] array.

Feel free to play around with this CodeSandbox demo.

Here's the code of the mixin. It's thoroughly commentated, so it should not be too hard to get an idea how it works:

function windowScrollPosition(propertyName) {
  return {
    data() {
      return {
        // Initialize scroll position at [0, 0]
        [propertyName]: [0, 0]
      }
    },
    created() {
      // Only execute this code on the client side, server sticks to [0, 0]
      if (!this.$isServer) {
        this._scrollListener = () => {
          // window.pageX/YOffset is equivalent to window.scrollX/Y, but works in IE
          // We round values because high-DPI devies can provide some really nasty subpixel values
          this[propertyName] = [
            Math.round(window.pageXOffset),
            Math.round(window.pageYOffset)
          ]
        }

        // Call listener once to detect initial position
        this._scrollListener()

        // When scrolling, update the position
        window.addEventListener('scroll', this._scrollListener)
      }
    },
    beforeDestroy() {
      // Detach the listener when the component is gone
      window.removeEventListener('scroll', this._scrollListener)
    }
  }
}

 DispatchQueue.main.async {
          self.collectionView?.reloadData() // Depends if you were populating a collection view or table view
    }


OperationQueue.main.addOperation {
    self.lblGenre.text = self.movGenre
}

//use Operation Queue if you need to populate the objects(labels, imageview, textview) on your viewcontroller

The config file is just an XML file, you can open it by:

private static XmlDocument loadConfigDocument()
{
    XmlDocument doc = null;
    try
    {
        doc = new XmlDocument();
        doc.Load(getConfigFilePath());
        return doc;
    }
    catch (System.IO.FileNotFoundException e)
    {
        throw new Exception("No configuration file found.", e);
    }
    catch (Exception ex)
    {
        return null;
    }
}

and later retrieving values by:

    // retrieve appSettings node

    XmlNode node =  doc.SelectSingleNode("//appSettings");

A good solution here for VSCode users, if a string breaking down into multiple lines causes the problem (I faced this when I had to test a long JWT token, and somehow using template literals didn't do the trick.)

The best way doing this - especially if you're adding more than one condition - is:

$values = array(...); // array of your values
$qb->andWhere('where', $qb->expr()->in('r.winner', $values));

If your array of values contains strings, you can't use the setParameter method with an imploded string, because your quotes will be escaped!

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin

End

Well my client side (a cshtml file) was using DataTables to display a grid (now using Infragistics control which are great). And once the user clicked on the row, I captured the row event and the date associated with that record in order to go back to the server and make additional server-side requests for trades, etc. And no - I DID NOT stringify it...

The DataTables def started as this (leaving lots of stuff out), and the click event is seen below where I PUSH onto my Json object :

    oTablePf = $('#pftable').dataTable({         // INIT CODE
             "aaData": PfJsonData,
             'aoColumnDefs': [                     
                { "sTitle": "Pf Id", "aTargets": [0] },
                { "sClass": "**td_nodedate**", "aTargets": [3] }
              ]
              });

   $("#pftable").delegate("tbody tr", "click", function (event) {   // ROW CLICK EVT!! 

        var rownum = $(this).index(); 
        var thisPfId = $(this).find('.td_pfid').text();  // Find Port Id and Node Date
        var thisDate = $(this).find('.td_nodedate').text();

         //INIT JSON DATA
        var nodeDatesJson = {
            "nodedatelist":[]
        };

         // omitting some code here...
         var dateArry = thisDate.split("/");
         var nodeDate = dateArry[2] + "-" + dateArry[0] + "-" + dateArry[1];

         nodeDatesJson.nodedatelist.push({ nodedate: nodeDate });

           getTradeContribs(thisPfId, nodeDatesJson);     // GET TRADE CONTRIBUTIONS 
    });

If you work with a terminal/cmd prompt open, and used any git commands that would have showed the unstaged changes (diff, add -p, checkout -p, etc.), and haven't closed the terminal/cmd prompt since, you'll find the unstaged changes are still available if you scroll up to where you ran those aforementioned git commands.

Are you sure the odbc connector is well created ? if not check the step "Create an ODBC Connection" again

EDIT: Connection without DSN from php.net

// Microsoft Access

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=$mdbFilename", $user, $password);

in your case it might be if your filename is northwind and your file extension mdb:

$connection = odbc_connect("Driver={Microsoft Access Driver (*.mdb)};Dbq=northwind", "", "");

In modes 'a' or 'a+', any writing is done at the end of the file, even if at the current moment when the write() function is triggered the file's pointer is not at the end of the file: the pointer is moved to the end of file before any writing. You can do what you want in two manners.

1st way, can be used if there are no issues to load the file into memory:

def line_prepender(filename, line):
    with open(filename, 'r+') as f:
        content = f.read()
        f.seek(0, 0)
        f.write(line.rstrip('\r\n') + '\n' + content)

2nd way:

def line_pre_adder(filename, line_to_prepend):
    f = fileinput.input(filename, inplace=1)
    for xline in f:
        if f.isfirstline():
            print line_to_prepend.rstrip('\r\n') + '\n' + xline,
        else:
            print xline,

I don't know how this method works under the hood and if it can be employed on big big file. The argument 1 passed to input is what allows to rewrite a line in place; the following lines must be moved forwards or backwards in order that the inplace operation takes place, but I don't know the mechanism

As you are probably aware, ints are stored internally in binary. Typically an int contains 32 bits, but in some environments might contain 16 or 64 bits (or even a different number, usually but not necessarily a power of two).

But for this example, let's look at 4-bit integers. Tiny, but useful for illustration purposes.

Since there are four bits in such an integer, it can assume one of 16 values; 16 is two to the fourth power, or 2 times 2 times 2 times 2. What are those values? The answer depends on whether this integer is a signed int or an unsigned int. With an unsigned int, the value is never negative; there is no sign associated with the value. Here are the 16 possible values of a four-bit unsigned int:

bits  value
0000    0
0001    1
0010    2
0011    3
0100    4
0101    5
0110    6
0111    7
1000    8
1001    9
1010   10
1011   11
1100   12
1101   13
1110   14
1111   15

... and Here are the 16 possible values of a four-bit signed int:

bits  value
0000    0
0001    1
0010    2
0011    3
0100    4
0101    5
0110    6
0111    7
1000   -8
1001   -7
1010   -6
1011   -5
1100   -4
1101   -3
1110   -2
1111   -1

As you can see, for signed ints the most significant bit is 1 if and only if the number is negative. That is why, for signed ints, this bit is known as the "sign bit".

In general this error message means that you have tried to use indexing on a function. You can reproduce this error message with, for example

mean[1]
## Error in mean[1] : object of type 'closure' is not subsettable
mean[[1]]
## Error in mean[[1]] : object of type 'closure' is not subsettable
mean$a
## Error in mean$a : object of type 'closure' is not subsettable

The closure mentioned in the error message is (loosely) the function and the environment that stores the variables when the function is called.

In this specific case, as Joshua mentioned, you are trying to access the url function as a variable. If you define a variable named url, then the error goes away.

As a matter of good practise, you should usually avoid naming variables after base-R functions. (Calling variables data is a common source of this error.)

There are several related errors for trying to subset operators or keywords.

`+`[1]
## Error in `+`[1] : object of type 'builtin' is not subsettable
`if`[1]
## Error in `if`[1] : object of type 'special' is not subsettable

If you're running into this problem in shiny, the most likely cause is that you're trying to work with a reactive expression without calling it as a function using parentheses.

library(shiny)
reactive_df <- reactive({
    data.frame(col1 = c(1,2,3),
               col2 = c(4,5,6))
})

While we often work with reactive expressions in shiny as if they were data frames, they are actually functions that return data frames (or other objects).

isolate({
    print(reactive_df())
    print(reactive_df()$col1)
})
  col1 col2
1    1    4
2    2    5
3    3    6
[1] 1 2 3

But if we try to subset it without parentheses, then we're actually trying to index a function, and we get an error:

isolate(
    reactive_df$col1
)
Error in reactive_df$col1 : object of type 'closure' is not subsettable

As for accessing elements, this article is pretty good for step by step way to encapsulate an array in the way you want:

How to ruby array

There are two problems with your query:

1. Every table and subquery needs a name, so you have to name the subquery INNER JOIN (SELECT ...) AS p ON ....
2. The subquery as you have it only returns one row period, but you actually want one row for each user. For that you need one query to get the max date and then self-join back to get the whole row.

Assuming there are no ties for payments.date, try:

    SELECT u.*, p.* 
    FROM (
        SELECT MAX(p.date) AS date, p.user_id 
        FROM payments AS p
        GROUP BY p.user_id
    ) AS latestP
    INNER JOIN users AS u ON latestP.user_id = u.id
    INNER JOIN payments AS p ON p.user_id = u.id AND p.date = latestP.date
    WHERE u.package = 1

I use the environment variable CDPATH

onchange will work only if the value of the textbox changed compared to the value it had before, so for the first time it won't work because the state didn't change.

So it is better to use onblur event or on submitting the form.

function checkTextField(field) {_x000D_
  document.getElementById("error").innerText =_x000D_
    (field.value === "") ? "Field is empty." : "Field is filled.";_x000D_
}

<input type="text" onblur="checkTextField(this);" />_x000D_
<p id="error"></p>

What role do they play when exiting an application in C#?

The same as every other application. Basically they get returned to the caller. Irrelvant if ythe start was an iicon double click. Relevant is the call is a batch file that decides whether the app worked on the return code. SO, unless you write a program that needs this, the return dcode IS irrelevant.

But what is the difference?

One comes from environment one from the System.Windows.Forms?.Application. Functionall there should not bbe a lot of difference.

Now (2021) the preferred way to use istanbul is via its "state of the art command line interface" nyc.

Setup

First, install it in your project with

npm i nyc --save-dev

Then, if you have a npm based project, just change the test script inside the scripts object of your package.json file to execute code coverage of your mocha tests:

{
  "scripts": {
    "test": "nyc --reporter=text mocha"
  }
}

Run

Now run your tests

npm test

and you will see a table like this in your console, just after your tests output:

Customization

Html report

Just use

nyc --reporter=html

instead of text. Now it will produce a report inside ./coverage/index.html.

Report formats

Istanbul supports a wide range of report formats. Just look at its reports library to find the most useful for you. Just add a --reporter=REPORTER_NAME option for each format you want. For example, with

nyc --reporter=html --reporter=text

you will have both the console and the html report.

Don't run coverage with npm test

Just add another script in your package.json and leave the test script with only your test runner (e.g. mocha):

{
  "scripts": {
    "test": "mocha",
    "test-with-coverage": "nyc --reporter=text mocha"
  }
}

Now run this custom script

npm run test-with-coverage

to run tests with code coverage.

Force test failing if code coverage is low

Fail if the total code coverage is below 90%:

nyc --check-coverage --lines 90 

Fail if the code coverage of at least one file is below 90%:

nyc --check-coverage --lines 90 --per-file

I'm going to answer my own question.

1. innerJoin should use the keyword "WITH" instead of "ON" (Doctrine's documentation [13.2.6. Helper methods] is inaccurate; [13.2.5. The Expr class] is correct)
2. no need to link foreign keys in join condition as they're already specified in the entity mapping.

Therefore, the following works for me

$qb->select('c')
    ->innerJoin('c.phones', 'p', 'WITH', 'p.phone = :phone')
    ->where('c.username = :username');

or

$qb->select('c')
    ->innerJoin('c.phones', 'p', Join::WITH, $qb->expr()->eq('p.phone', ':phone'))
    ->where('c.username = :username');

If you want to get the date when the user selects it, you can do this:

$("#datepicker").datepicker({
    onSelect: function() { 
        var dateObject = $(this).datepicker('getDate'); 
    }
});

I am not sure about the second part of your question. But, have you tried using style sheets and relative positioning?
