Programs & Examples On #Nmock

If it has to be accessible with a global scope

global.fetch = require("node-fetch");

This is a quick dirty fix, please try to eliminate this usage in production code.

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";
  }

  public static int getInt() {
    return 1;
  }
}

@RunWith(PowerMockRunner.class)
@PrepareForTest(ClassWithStatics.class)
public class StubJustOneStatic {
  @Test
  public void test() {
    PowerMockito.mockStatic(ClassWithStatics.class);

    when(ClassWithStatics.getString()).thenReturn("Hello!");

    System.out.println("String: " + ClassWithStatics.getString());
    System.out.println("Int: " + ClassWithStatics.getInt());
  }
}

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

Another easy way to do so:

import org.mockito.BDDMockito;    
import static org.mockito.Matchers.argThat;
import org.mockito.ArgumentMatcher;

BDDMockito.verify(mockedObject)
        .someMethodOnMockedObject(argThat(new ArgumentMatcher<TypeOfMethodArg>() {

            @Override
            public boolean matches(Object argument) {
                final TypeOfMethodArg castedArg = (TypeOfMethodArg) argument;

                // Make your verifications and return a boolean to say if it matches or not
                boolean isArgMarching = true;

                return isArgMarching;
            }
        }));

if you are using vs code just try using background:url("img/bimg.jpg") instead of background:url('img/bimg.jpg') Mine worked at it Nothing much I replaced ' with "

Taking the value from Command line and showing THE INPUT IS DECIMAL/NON-DECIMAL and NUMBER or not:

NUMBER=$1

            IsDecimal=`echo "$NUMBER" | grep "\."`

if [ -n "$IsDecimal" ]
then
            echo "$NUMBER is Decimal"
            var1=`echo "$NUMBER" | cut -d"." -f1`
            var2=`echo "$NUMBER" | cut -d"." -f2`

            Digit1=`echo "$var1" | egrep '^-[0-9]+$'`
            Digit2=`echo "$var1" | egrep '^[0-9]+$'`
            Digit3=`echo "$var2" | egrep '^[0-9]+$'`


            if [ -n "$Digit1" ] && [ -n "$Digit3" ]
            then
                echo "$NUMBER is a number"
            elif [ -n "$Digit2" ] && [ -n "$Digit3" ]
            then
                echo "$NUMBER is a number"

            else
                echo "$NUMBER is not a number"
            fi
else
            echo "$NUMBER is not Decimal"

            Digit1=`echo "$NUMBER" | egrep '^-[0-9]+$'`
            Digit2=`echo "$NUMBER" | egrep '^[0-9]+$'`

            if [ -n "$Digit1" ] || [ -n "$Digit2" ]; then
                echo "$NUMBER is a number"
            else
                echo "$NUMBER is not a number"
            fi

1. .vs folder should not be committed.
2. create a file with name ".gitignore" inside the projects git root directory.
3. Add the following line ".vs/" in ".gitignore" file.
4. Now commit your project.

The whole code if somebody need it.

void alarm(Context context, Calendar calendar) {
    AlarmManager alarmManager = (AlarmManager)context.getSystemService(ALARM_SERVICE);

    final String SOME_ACTION = "com.android.mytabs.MytabsActivity.AlarmReceiver";
    IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

    AlarmReceiver mReceiver = new AlarmReceiver();
    context.registerReceiver(mReceiver, intentFilter);

    Intent anotherIntent = new Intent(SOME_ACTION);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, anotherIntent, 0);
    alramManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

    Toast.makeText(context, "Added", Toast.LENGTH_LONG).show();
}

class AlarmReceiver extends BroadcastReceiver {     
    @Override
    public void onReceive(Context context, Intent arg1) {
        Toast.makeText(context, "Started", Toast.LENGTH_LONG).show();
    }
}

byte b = (byte)0xC8;
int v1 = b;       // v1 is -56 (0xFFFFFFC8)
int v2 = b & 0xFF // v2 is 200 (0x000000C8)

Most of the time v2 is the way you really need.

Here is my final solution. It works fine with a large amount of data. I use Timer to make sure the user want find current value. It looks like complex but it doesn't. Thanks to Max Lambertini for the idea.

        private bool _canUpdate = true; 

        private bool _needUpdate = false;       

        //If text has been changed then start timer
        //If the user doesn't change text while the timer runs then start search
        private void combobox1_TextChanged(object sender, EventArgs e)
        {
            if (_needUpdate)
            {
                if (_canUpdate)
                {
                    _canUpdate = false;
                    UpdateData();                   
                }
                else
                {
                    RestartTimer();
                }
            }
        }

        private void UpdateData()
        {
            if (combobox1.Text.Length > 1)
            {
                List<string> searchData = Search.GetData(combobox1.Text);
                HandleTextChanged(searchData);
            }
        }       

        //If an item was selected don't start new search
        private void combobox1_SelectedIndexChanged(object sender, EventArgs e)
        {
            _needUpdate = false;
        }

        //Update data only when the user (not program) change something
        private void combobox1_TextUpdate(object sender, EventArgs e)
        {
            _needUpdate = true;
        }

        //While timer is running don't start search
        //timer1.Interval = 1500;
        private void RestartTimer()
        {
            timer1.Stop();
            _canUpdate = false;
            timer1.Start();
        }

        //Update data when timer stops
        private void timer1_Tick(object sender, EventArgs e)
        {
            _canUpdate = true;
            timer1.Stop();
            UpdateData();
        }

        //Update combobox with new data
        private void HandleTextChanged(List<string> dataSource)
        {
            var text = combobox1.Text;

            if (dataSource.Count() > 0)
            {
                combobox1.DataSource = dataSource;  

                var sText = combobox1.Items[0].ToString();
                combobox1.SelectionStart = text.Length;
                combobox1.SelectionLength = sText.Length - text.Length;
                combobox1.DroppedDown = true;


                return;
            }
            else
            {
                combobox1.DroppedDown = false;
                combobox1.SelectionStart = text.Length;
            }
        }

This solution isn't very cool. So if someone has another solution please share it with me.

Just type

document.querySelector('video').playbackRate = 1.25;

in JS console of your modern browser.

Another potential cause:

I had this issue when I was accidentally presenting the same view controller twice. (Once with performSegueWithIdentifer:sender: which was called when the button was pressed, and a second time with a segue connected directly to the button).

Effectively, two segues were firing at the same time, and I got the error: Attempt to present X on Y whose view is not in the window hierarchy!

simply,

select sysdate-1 from dual

there's a bunch more info and detail here: http://www.orafaq.com/faq/how_does_one_add_a_day_hour_minute_second_to_a_date_value

For R-Markdown, neither of the above solutions worked for me, so I turned to regular LaTeX syntax, which works just fine.

\begin{figure}
 \includegraphics[width=300pt, height = 125 pt]{drawing.jpg}
\end{figure}

Then you can use e.g. the \begin{center} statement to center the image.

This error was caused by importing the wrong Id class. After changing org.springframework.data.annotation.Id to javax.persistence.Id the application run

Use RegExp, In case if any other options do not work for you, RegExp is a good option. It makes the string case insensitive.

var username = new RegExp("^" + "John" + "$", "i");;

use username in queries, and then its done.

I hope it will work for you too. All the Best.

For enable PHP Extension intl , follow the Steps..

1. Open the xampp/php/php.ini file in any editor.
2. Search ";extension=php_intl.dll"
3. kindly remove the starting semicolon ( ; ) Like : ;extension=php_intl.dll. to. extension=php_intl.dll.
4. Save the xampp/php/php.ini file.
5. Restart your xampp/wamp.

It's super simple

using (var dbContext = new DbContextBuilder().BuildDbContext())
{
    dbContext.Update(entity);
    await dbContext.SaveChangesAsync();
}

In doubt change your editor to make tabs and spaces visible. It is also a very good idea to have the editor resolve all tabs to 4 spaces.

Beginning with C# 7.3, you can use closer approximation - the unmanaged constraint to specify that a type parameter is a non-pointer, non-nullable unmanaged type.

class SomeGeneric<T> where T : unmanaged
{
//...
}

The unmanaged constraint implies the struct constraint and can't be combined with either the struct or new() constraints.

A type is an unmanaged type if it's any of the following types:

• sbyte, byte, short, ushort, int, uint, long, ulong, char, float, double, decimal, or bool
• Any enum type
• Any pointer type
• Any user-defined struct type that contains fields of unmanaged types only and, in C# 7.3 and earlier, is not a constructed type (a type that includes at least one type argument)

To restrict further and eliminate pointer and user-defined types that do not implement IComparable add IComparable (but enum is still derived from IComparable, so restrict enum by adding IEquatable < T >, you can go further depending on your circumstances and add additional interfaces. unmanaged allows to keep this list shorter):

    class SomeGeneric<T> where T : unmanaged, IComparable, IEquatable<T>
    {
    //...
    }

But this doesn't prevent from DateTime instantiation.

For me it must have:

mongod --dbpath=/whatever/data/path

Use a truly blank, valid and highly compatible SVG, based on this article:

src="data:image/svg+xml;charset=utf8,%3Csvg%20xmlns='http://www.w3.org/2000/svg'%3E%3C/svg%3E"

It will default in size to 300x150px as any SVG does, but you can work with that in your img element default styles, as you would possibly need in any case in the practical implementation.

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)
    }
}

Unfortunately it seems to be a issue with MySql usage of "NOT IN" clause, the screen-shoot below shows the sub-query option returning wrong results:

public enum MyEnum {
   ONE(1),
   TWO(2);
   private int value;
   private MyEnum(int value) {
      this.value = value;
   }
   public int getValue() {
      return value;
   }
}

In short - you can define any number of parameters for the enum as long as you provide constructor arguments (and set the values to the respective fields)

As Scott noted - the official enum documentation gives you the answer. Always start from the official documentation of language features and constructs.

Update: For strings the only difference is that your constructor argument is String, and you declare enums with TEST("test")

First a CMP (comparison) instruction is called then one of the following:

jle - jump to line if less than or equal to
jge - jump to line if greater than or equal to

The lowest assembler works with is bytes, not bits (directly anyway). If you want to know about bit logic you'll need to take a look at circuit design.

Just put the full directory location in the File object.

File file = new File("z:\\results.txt");

I would use something like this.

 public class MyViewModel
    {
            public MyDataTable Data { get; set; }
            public MyViewModel()
               {
                   loadData(() => GetData());
               }
               private async void loadData(Func<DataTable> load)
               {
                  try
                  {
                      MyDataTable = await Task.Run(load);
                  }
                  catch (Exception ex)
                  {
                       //log
                  }
               }
               private DataTable GetData()
               {
                    DataTable data;
                    // get data and return
                    return data;
               }
    }

This is as close to I can get for constructors.

Actually we can do it. we can set the file value default by using webbrowser control in c# using FormToMultipartPostData Library.We have to download and include this Library in our project. Webbrowser enables the user to navigate Web pages inside form. Once the web page loaded , the script inside the webBrowser1_DocumentCompleted will be executed. So,

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
    {
       FormToMultipartPostData postData = 
            new FormToMultipartPostData(webBrowser1, form);
        postData.SetFile("fileField", @"C:\windows\win.ini");
        postData.Submit();
    }

Your query would work already - except that you are running into naming conflicts or just confusing the output column (the CASE expression) with source column result, which has different content.

...
GROUP BY model.name, attempt.type, attempt.result
...

You need to GROUP BY your CASE expression instead of your source column:

...
GROUP BY model.name, attempt.type
       , CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END
...

Or provide a column alias that's different from any column name in the FROM list - or else that column takes precedence:

SELECT ...
     , CASE WHEN attempt.result = 0 THEN 0 ELSE 1 END AS result1
...
GROUP BY model.name, attempt.type, result1
...

The SQL standard is rather peculiar in this respect. Quoting the manual here:

An output column's name can be used to refer to the column's value in ORDER BY and GROUP BY clauses, but not in the WHERE or HAVING clauses; there you must write out the expression instead.

And:

If an ORDER BY expression is a simple name that matches both an output column name and an input column name, ORDER BY will interpret it as the output column name. This is the opposite of the choice that GROUP BY will make in the same situation. This inconsistency is made to be compatible with the SQL standard.

Bold emphasis mine.

These conflicts can be avoided by using positional references (ordinal numbers) in GROUP BY and ORDER BY, referencing items in the SELECT list from left to right. See solution below.
The drawback is, that this may be harder to read and vulnerable to edits in the SELECT list (one might forget to adapt positional references accordingly).

But you do not have to add the column day to the GROUP BY clause, as long as it holds a constant value (CURRENT_DATE-1).

Rewritten and simplified with proper JOIN syntax and positional references it could look like this:

SELECT m.name
     , a.type
     , CASE WHEN a.result = 0 THEN 0 ELSE 1 END AS result
     , CURRENT_DATE - 1 AS day
     , count(*) AS ct
FROM   attempt    a
JOIN   prod_hw_id p USING (hard_id)
JOIN   model      m USING (model_id)
WHERE  ts >= '2013-11-06 00:00:00'  
AND    ts <  '2013-11-07 00:00:00'
GROUP  BY 1,2,3
ORDER  BY 1,2,3;

Also note that I am avoiding the column name time. That's a reserved word and should never be used as identifier. Besides, your "time" obviously is a timestamp or date, so that is rather misleading.

When I tried to set theme attribute to TextInputLayout, the theme was also getting applied to its child view edittext, which I didn't wanted.

So the solution which worked for me was to add a custom style to the "app:hintTextAppearance" property of the TextInputLayout.

In styles.xml add the following style:

<style name="TextInputLayoutTextAppearance" parent="TextAppearance.AppCompat">
    <item name="android:textColor">@color/text_color</item>
    <item name="android:textSize">@dimen/text_size_12</item>
</style>

And apply this style to the "app:hintTextAppearance" property of the TextInputLayout as below:

<com.google.android.material.textfield.TextInputLayout
        android:id="@+id/mobile_num_til"
        android:layout_width="0dp"
        android:layout_height="@dimen/dim_56"
        app:layout_constraintStart_toStartOf="@id/title_tv"
        app:layout_constraintEnd_toEndOf="@id/title_tv"
        app:layout_constraintTop_toBottomOf="@id/sub_title_tv"
        android:layout_marginTop="@dimen/dim_30"
        android:padding="@dimen/dim_8"
        app:hintTextAppearance="@style/TextInputLayoutTextAppearance"
        android:background="@drawable/rect_round_corner_grey_outline">

        <com.google.android.material.textfield.TextInputEditText
            android:id="@+id/mobile_num_et"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:hint="@string/mobile_number"
            android:gravity="center_vertical"
            android:background="@android:color/transparent"/>

    </com.google.android.material.textfield.TextInputLayout>

To make reading of this page more valuable (for future search results) I made a list of libraries known to me.. As @CommonsWare mentioned there are super-similar questions/answers.. Anyway some libraries that can be used for making charts are:

Open Source:

• AnyChart (Free for non-commercial, Paid for commercial)
• MPAndroidChart
• Holo Graph Library
• aChartEngine
• ChartView
• aFreeChart
• ChartDroid
• charts4j
• GraphView
• AndroidPlot
• Drawing the 3D piechart Using Google chart Api
• WilliamChart
• HelloCharts
• ChartProgressBar
• Plot.ly

Paid:

• aiCharts
• RChart (pre Honeycomb - Api 11 UI)
• ShinobiControls **
• Steema TeeChart **
• Orson Charts (3D charts for Android)
• Telerik Rad Chart
• SciChart (Realtime Charts for Android)

** - means I didn't try those so I can't really recommend it but other users suggested it..

Just a note

The following arrays:

string[] array = new string[2];
string[] array2 = new string[] { "A", "B" };
string[] array3 = { "A" , "B" };
string[] array4 = new[] { "A", "B" };

Will be compiled to:

string[] array = new string[2];
string[] array2 = new string[] { "A", "B" };
string[] array3 = new string[] { "A", "B" };
string[] array4 = new string[] { "A", "B" };

The same as David's, but without attr()

$('<input>', {
    type: 'hidden',
    id: 'foo',
    name: 'foo',
    value: 'bar'
}).appendTo('form');

I haven't done much testing with this but it seems to work. Here's what I came up with:

namespace OrtzIRC.WPF
{
    using System;
    using System.Windows;
    using OrtzIRC.WPF.ViewModels;

    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application
    {
        private MainViewModel viewModel = new MainViewModel();
        private MainWindow window = new MainWindow();

        protected override void OnStartup(StartupEventArgs e)
        {
            base.OnStartup(e);

            viewModel.RequestClose += ViewModelRequestClose;

            window.DataContext = viewModel;
            window.Closing += Window_Closing;
            window.Show();
        }

        private void ViewModelRequestClose(object sender, EventArgs e)
        {
            viewModel.RequestClose -= ViewModelRequestClose;
            window.Close();
        }

        private void Window_Closing(object sender, System.ComponentModel.CancelEventArgs e)
        {
            window.Closing -= Window_Closing;
            viewModel.RequestClose -= ViewModelRequestClose; //Otherwise Close gets called again
            viewModel.CloseCommand.Execute(null);
        }
    }
}

Kind of an old question, but I thought I should throw in a method which wasn't widely available when this question was asked.

You can reverse the side of the scrollbar in modern browsers using transform: scaleX(-1) on a parent <div>, then apply the same transform to reverse a child, "sleeve" element.

HTML

<div class="parent">
  <div class="sleeve">
    <!-- content -->
  </div>
</div>

CSS

.parent {
  overflow: auto;
  transform: scaleX(-1); //Reflects the parent horizontally
}

.sleeve {
  transform: scaleX(-1); //Flips the child back to normal
}

Note: You may need to use an -ms-transform or -webkit-transform prefix for browsers as old as IE 9. Check CanIUse and click "show all" to see older browser requirements.

Here's some full and simple code to do this. This worked fine when I used it.

var processStartInfo = new ProcessStartInfo
{
    FileName = @"C:\SomeProgram",
    Arguments = "Arguments",
    RedirectStandardOutput = true,
    UseShellExecute = false
};
var process = Process.Start(processStartInfo);
var output = process.StandardOutput.ReadToEnd();
process.WaitForExit();

Note that this only captures standard output; it doesn't capture standard error. If you want both, use this technique for each stream.

Ultimately they both produce the same HTML but Html.TextBoxFor() is strongly typed where as Html.TextBox isn't.

1:  @Html.TextBox("Name")
2:  Html.TextBoxFor(m => m.Name)

will both produce

<input id="Name" name="Name" type="text" />

So what does that mean in terms of use?

Generally two things:

1. The typed TextBoxFor will generate your input names for you. This is usually just the property name but for properties of complex types can include an underscore such as 'customer_name'
2. Using the typed TextBoxFor version will allow you to use compile time checking. So if you change your model then you can check whether there are any errors in your views.

It is generally regarded as better practice to use the strongly typed versions of the HtmlHelpers that were added in MVC2.

I just changed the Network settings from Native to Manual, restart and the error is gone.

I'm using RAD 8.0.4.3 with and old version of EGit connected to TFS/Git. ;-)

Uninitialized non-static members will contain random data. Actually, they will just have the value of the memory location they are assigned to.

Of course for object parameters (like string) the object's constructor could do a default initialization.

In your example:

int *ptr; // will point to a random memory location
string name; // empty string (due to string's default costructor)
string *pname; // will point to a random memory location
string &rname; // it would't compile
const string &crname; // it would't compile
int age; // random value

rsplit should be up to the task:

In [1]: 'http://www.test.com/page/TEST2'.rsplit('/', 1)[1]
Out[1]: 'TEST2'

Top down and bottom up DP are two different ways of solving the same problems. Consider a memoized (top down) vs dynamic (bottom up) programming solution to computing fibonacci numbers.

fib_cache = {}

def memo_fib(n):
  global fib_cache
  if n == 0 or n == 1:
     return 1
  if n in fib_cache:
     return fib_cache[n]
  ret = memo_fib(n - 1) + memo_fib(n - 2)
  fib_cache[n] = ret
  return ret

def dp_fib(n):
   partial_answers = [1, 1]
   while len(partial_answers) <= n:
     partial_answers.append(partial_answers[-1] + partial_answers[-2])
   return partial_answers[n]

print memo_fib(5), dp_fib(5)

I personally find memoization much more natural. You can take a recursive function and memoize it by a mechanical process (first lookup answer in cache and return it if possible, otherwise compute it recursively and then before returning, you save the calculation in the cache for future use), whereas doing bottom up dynamic programming requires you to encode an order in which solutions are calculated, such that no "big problem" is computed before the smaller problem that it depends on.

I gathered all what others have suggested and created following function which has 3 arguments, the number and the base which that number has come from and the base which that number is going to be on:

changeBase(1101000, 2, 10) => 104

Run Code Snippet to try it yourself:

function changeBase(number, fromBase, toBase) {_x000D_
                        if (fromBase == 10)_x000D_
                            return (parseInt(number)).toString(toBase)_x000D_
                        else if (toBase == 10)_x000D_
                            return parseInt(number, fromBase);_x000D_
                        else{_x000D_
                            var numberInDecimal = parseInt(number, fromBase);_x000D_
                            return (parseInt(numberInDecimal)).toString(toBase);_x000D_
                    }_x000D_
}_x000D_
_x000D_
$("#btnConvert").click(function(){_x000D_
  var number = $("#txtNumber").val(),_x000D_
  fromBase = $("#txtFromBase").val(),_x000D_
  toBase = $("#txtToBase").val();_x000D_
  $("#lblResult").text(changeBase(number, fromBase, toBase));_x000D_
});

#lblResult{_x000D_
  padding: 20px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<input id="txtNumber" type="text" placeholder="Number" />_x000D_
<input id="txtFromBase" type="text" placeholder="From Base" />_x000D_
<input id="txtToBase" type="text" placeholder="To Base" />_x000D_
<input id="btnConvert" type="button" value="Convert" />_x000D_
<span id="lblResult"></span>_x000D_
_x000D_
<p>Hint: <br />_x000D_
Try 110, 2, 10 and it will return 6; (110)<sub>2</sub> = 6<br />_x000D_
_x000D_
or 2d, 16, 10 => 45 meaning: (2d)<sub>16</sub> = 45<br />_x000D_
or 45, 10, 16 => 2d meaning: 45 = (2d)<sub>16</sub><br />_x000D_
or 2d, 2, 16 => 2d meaning: (101101)<sub>2</sub> = (2d)<sub>16</sub><br />_x000D_
</p>

FYI: If you want to pass 2d as hex number, you need to send it as a string so it goes like this: changeBase('2d', 16, 10)

date = new DateTime(date.year, date.month, date.day, HH, MM, SS);

You can use

map(lambda a : chr(a),  np.random.randint(low=65, high=90, size=4))

You can try cactoos for that.

final InputStream input = new InputStreamOf("example");

The object is created with new and not a static method for a reason.

Lately I have used this pattern in my forms to check names of people, containing letters, blanks and special characters like accent marks.

pattern="[A-zÀ-ú\s]+"

Furthermore, you also have || which is the logical or, and also ; which is just a separator which doesn't care what happend to the command before.

$ false || echo "Oops, fail"
Oops, fail

$ true || echo "Will not be printed"
$  

$ true && echo "Things went well"
Things went well

$ false && echo "Will not be printed"
$

$ false ; echo "This will always run"
This will always run

Some details about this can be found here Lists of Commands in the Bash Manual.

I prefer Serializable = no boilerplate code. For passing data to other Fragments or Activities the speed difference to a Parcelable does not matter.

I would also always provide a helper method for a Fragment or Activity, this way you always know, what data has to be passed. Here an example for your ListMusicFragment:

private static final String EXTRA_MUSIC_LIST = "music_list";

public static ListMusicFragment createInstance(List<Music> music) {
    ListMusicFragment fragment = new ListMusicFragment();
    Bundle bundle = new Bundle();
    bundle.putSerializable(EXTRA_MUSIC_LIST, music);
    fragment.setArguments(bundle);
    return fragment;
}

@Override
public View onCreateView(...) { 
    ...
    Bundle bundle = intent.getArguments();
    List<Music> musicList = (List<Music>)bundle.getSerializable(EXTRA_MUSIC_LIST);
    ...
}

I had to put some the displayed javascripts above inside the "document.ready" code. Otherwise they didn't work. Probably obvious for many, but not for me. So if you're testing look at that option.

<script type="text/javascript">
$(document).ready(function(){
//rest of the javascript code here
});
</script>

The usual API for this is DirectShow.

You can use P/Invoke to import the C++ APIs, but I think there are already a few projects out there that have done this.

http://channel9.msdn.com/forums/TechOff/93476-Programatically-Using-A-Webcam-In-C/

http://www.codeproject.com/KB/directx/DirXVidStrm.aspx

To get the streaming part, you probably want to use DirectShow to apply a compression codec to reduce lag, then you can get a Stream and transmit it. You could consider using multicast to reduce network load.

Serialisation in java is not meant as long term persistence or transport format - it is too fragile for this. With the slightest difference in class bytecode and JVM, your data is not readable anymore. Use XML or JSON data-binding for your task (XStream is fast and easy to use, and there are a ton of alternatives)

df = pd.DataFrame({'movie': ['thg', 'thg', 'mol', 'mol', 'lob', 'lob'],'rating': [3., 4., 5., np.nan, np.nan, np.nan],'name': ['John','James', np.nan, np.nan, np.nan,np.nan]})

for col in df.columns:
    df = df[~pd.isnull(df[col])]

for my use case, i wanted to grab the SHA1 hash from the magisk config file. the below worked for me.

adb shell "su -c "cat /sbin/.magisk/config | grep SHA | awk -F= '{ print $2 }'""

It's because the in.nextInt() doesn't change line. So you first "enter" (after you press 3 ) cause the endOfLine read by your in.nextLine() in your loop.

Here a small change that you can do:

int nnames;
    String names[];

    System.out.print("How many names are you going to save: ");
    Scanner in = new Scanner(System.in);
    nnames = Integer.parseInt(in.nextLine());
    names = new String[nnames];

    for (int i = 0; i < names.length; i++){
            System.out.print("Type a name: ");
            names[i] = in.nextLine();
    }

The way I do it: I store the latitude and longitude and then I have a third column which is a automatic derived geography type of the 1st two columns. The table looks like this:

CREATE TABLE [dbo].[Geopoint]
(
    [GeopointId] BIGINT NOT NULL PRIMARY KEY IDENTITY, 
    [Latitude] float NOT NULL, 
    [Longitude] float NOT NULL, 
    [ts] ROWVERSION NOT NULL, 
    [GeographyPoint]  AS ([geography]::STGeomFromText(((('POINT('+CONVERT([varchar](20),[Longitude]))+' ')+CONVERT([varchar](20),[Latitude]))+')',(4326))) 
)

This gives you the flexibility of spatial queries on the geoPoint column and you can also retrieve the latitude and longitude values as you need them for display or extracting for csv purposes.

Create an alias for gcc with your favorite includes.

alias mygcc='gcc -I /whatever/'

You need to aggregate the data first, this can be done using the GROUP BY clause:

SELECT Group, COUNT(*)
FROM table
GROUP BY Group
ORDER BY COUNT(*) DESC

The DESC keyword allows you to show the highest count first, ORDER BY by default orders in ascending order which would show the lowest count first.

If you want to add a single view multiple time then you have to use

   layoutInflaterForButton = getActivity().getLayoutInflater();

 for (int noOfButton = 0; noOfButton < 5; noOfButton++) {
        FrameLayout btnView = (FrameLayout) layoutInflaterForButton.inflate(R.layout.poll_button, null);
        btnContainer.addView(btnView);
    }

If you do like

   layoutInflaterForButton = getActivity().getLayoutInflater();
    FrameLayout btnView = (FrameLayout) layoutInflaterForButton.inflate(R.layout.poll_button, null);

and

for (int noOfButton = 0; noOfButton < 5; noOfButton++) {
            btnContainer.addView(btnView);
        }

then it will throw exception of all ready added view.

Downcasting transformation of objects is not possible. Only

For this you can simply use the redirect function that is included in flask

from flask import Flask, redirect

app = Flask(__name__)

@app.route('/')
def hello():
    return redirect("https://www.exampleURL.com", code = 302)

if __name__ == "__main__":
    app.run()

Another useful tip(as you're new to flask), is to add app.debug = True after initializing the flask object as the debugger output helps a lot while figuring out what's wrong.

For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:

/Applications/mampstack-7.1.21-0/php/bin

1. In terminal run vim ~/.bash_profile to open ~/.bash_profile

2. Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:

   export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"

3. Hit ESC, Type :wq, and hit Enter

4. In Terminal run source ~/.bash_profile
5. In Terminal type which php, output should be the path to MAMP PHP install.

In python automatic garbage collection deallocates the variable (pandas DataFrame are also just another object in terms of python). There are different garbage collection strategies that can be tweaked (requires significant learning).

You can manually trigger the garbage collection using

import gc
gc.collect()

But frequent calls to garbage collection is discouraged as it is a costly operation and may affect performance.

Reference

int titleId = getResources().getIdentifier("action_bar_title", "id",
            "android");
    TextView yourTextView = (TextView) findViewById(titleId);
    yourTextView.setTextColor(getResources().getColor(R.color.black));
    yourTextView.setTypeface(face);

You don't need to create an intermediate file. You can do

pg_dump -C -h localhost -U localuser dbname | psql -h remotehost -U remoteuser dbname

or

pg_dump -C -h remotehost -U remoteuser dbname | psql -h localhost -U localuser dbname

using psql or pg_dump to connect to a remote host.

With a big database or a slow connection, dumping a file and transfering the file compressed may be faster.

As Kornel said there is no need to dump to a intermediate file, if you want to work compressed you can use a compressed tunnel

pg_dump -C dbname | bzip2 | ssh  remoteuser@remotehost "bunzip2 | psql dbname"

or

pg_dump -C dbname | ssh -C remoteuser@remotehost "psql dbname"

but this solution also requires to get a session in both ends.

Note: pg_dump is for backing up and psql is for restoring. So, the first command in this answer is to copy from local to remote and the second one is from remote to local. More -> https://www.postgresql.org/docs/9.6/app-pgdump.html

Here is the way to access :after and :before style properties, defined in css:

// Get the color value of .element:before
var color = window.getComputedStyle(
    document.querySelector('.element'), ':before'
).getPropertyValue('color');

// Get the content value of .element:before
var content = window.getComputedStyle(
    document.querySelector('.element'), ':before'
).getPropertyValue('content');

My preferred method for doing this is via a hash function (borrowed from here). This allows you to utilize the efficiency of a switch statement even when working with char *'s:

#include "stdio.h"

#define LS 5863588
#define CD 5863276
#define MKDIR 210720772860
#define PWD 193502992

const unsigned long hash(const char *str) {
    unsigned long hash = 5381;  
    int c;

    while ((c = *str++))
        hash = ((hash << 5) + hash) + c;
    return hash;
}

int main(int argc, char *argv[]) {
    char *p_command = argv[1];
    switch(hash(p_command)) {
    case LS:
        printf("Running ls...\n");
        break;
    case CD:
        printf("Running cd...\n");
        break;
    case MKDIR:
        printf("Running mkdir...\n");
        break;
    case PWD:
        printf("Running pwd...\n");
        break;
    default:
        printf("[ERROR] '%s' is not a valid command.\n", p_command);
    }
}

Of course, this approach requires that the hash values for all possible accepted char *'s are calculated in advance. I don't think this is too much of an issue; however, since the switch statement operates on fixed values regardless. A simple program can be made to pass char *'s through the hash function and output their results. These results can then be defined via macros as I have done above.

Maybe, this approach is better, https://saucelabs.com/mobile, mobile testing in the cloud with selenium

Zero and None both treated as same for if block, below code should work fine.

if number or number==0:
    return True

First, you can switch on an enum in Java. I'm guessing you intended to say you can’t, but you can. chars have a set range of values, so it's easy to compare. Strings can be anything.

A switch statement is usually implemented as a jump table (branch table) in the underlying compilation, which is only possible with a finite set of values. C# can switch on strings, but it causes a performance decrease because a jump table cannot be used.

Java 7 and later supports String switches with the same characteristics.

Yes.

<head>
<script type='javascript'>
var x = 0;
</script>
</head>
<body>
  <input type='button' onclick='x++;'/>
</body>

[Psuedo code, god I hope this is right.]

I think this could help you:

let timeNow = time(nil)
let aStr = String(format: "%@%x", "timeNow in hex: ", timeNow)
print(aStr)

Example result:

timeNow in hex: 5cdc9c8d

I know this is way old, but I have a really cool way of doing this that is worth sharing.

What is required in Conemu and WinSCP. These are simple instructions

1. Open WinSCP.exe and login to my desired remote server (I have
   found that it's important to login before attaching ... ).

2. In the preferences for WinSCP - two settings to change. Choose Explorer type interface and rather than Commander - so you don't see local files. Unless you want to (but that seems like it would suck here). Set up Sublime as your default editor.

3. With ConEmu open, right click the tab bar and select the option Attach to.... A dialog box will open with your running applications. Choose, WinSCP and select OK. ConEmu will now have an open tab with WinSCP displaying your remote files.

4. Right click on the WinSCP tab and choose New console.... When the dialog box opens, enter the path to the Sublime executable on your system. Before you press Start, In the box that says New console split select the radio button to right and set the percentage. I usually choose 75%, but you can customize this to your liking, and it can be changed later.

   5. Now you will see Sublime in the same window running to the right of WinSCP. In Sublime, from the View menu, choose Sidebar->Hide Sidebar, and bam, you now have remote files in exactly the same manner as you would locally - with a few caveats of course that comes with editing anything remotely. WinSCP is lightening fast though.

I have two monitors - left monitor display's Chrome browser, right monitor displays code editor. Also in ConEmu, I create another tab and ssh into the site I'm working on, so I can do things like run gulp or grunt remotely and also manipulate files from the command line. Seriously sped up development.

Here's a screenshot:

If your example represents your real code, the problem is not in the push, it's that your constructor doesn't do anything.

You need to declare and initialize the x and y members.

Explicitly:

export class Pixel {
    public x: number;
    public y: number;   
    constructor(x: number, y: number) {
        this.x = x;
        this.y = y;
    }
}

Or implicitly:

export class Pixel {
    constructor(public x: number, public y: number) {}
}

You need sp_addlinkedserver()

http://msdn.microsoft.com/en-us/library/ms190479.aspx

Example:

exec sp_addlinkedserver @server = 'test'

then

select * from [server].[database].[schema].[table]

In your example:

select * from [test].[testdb].[dbo].[table]

np.save('data.npy', num_arr) # save
new_num_arr = np.load('data.npy') # load

... is syntax for variadic arguments.

I think it is implemented by the complier using slice ([]Type), just like the function append :

func append(slice []Type, elems ...Type) []Type

when you use "elems" in "append", actually it is a slice([]type). So "a = append(a[:0], a[1:]...)" means "a = append(a[0:0], a[1:])"

a[0:0] is a slice which has nothing

a[1:] is "Hello2 Hello3"

This is how it works

I have created a simple custom touch listener class instead of a custom EditText

public class MyTouchListener implements View.OnTouchListener {
private EditText editText;

public MyTouchListener(EditText editText) {
    this.editText = editText;

    setupDrawable(this.editText);
}

private void setupDrawable(final EditText editText) {
    editText.addTextChangedListener(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(s.length()>0)
                editText.setCompoundDrawablesWithIntrinsicBounds(0,0, R.drawable.clearicon,0);
            else
                editText.setCompoundDrawablesWithIntrinsicBounds(0,0, 0,0);

        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });
}

@Override
public boolean onTouch(View v, MotionEvent event) {
    if(event.getAction() == MotionEvent.ACTION_UP) {
        if(editText.getCompoundDrawables()[2]!=null){
            if(event.getX() >= (editText.getRight()- editText.getLeft() - editText.getCompoundDrawables()[2].getBounds().width())) {
                editText.setText("");
            }
        }
    }
    return false;

}

}

There will be no drawable when the EditText is blank. A drawable will show when we started editing for clear the EditText.

You can just set the touch listener

mEditText.setOnTouchListener(new MyTouchListener(mEditText));

If you take a look at the constructors called from the LinkedHashSet class you will see that internally it's a LinkedHashMap that is used for backing purpose.

for example:

- for (var i = 0; i < 10; ++i) {
  li= array[i]
- }

you may see https://github.com/visionmedia/jade for detailed document.

use the dbms_metadata package, as described here

If the DataFrame is huge, and the number of rows to drop is large as well, then simple drop by index df.drop(df.index[]) takes too much time.

In my case, I have a multi-indexed DataFrame of floats with 100M rows x 3 cols, and I need to remove 10k rows from it. The fastest method I found is, quite counterintuitively, to take the remaining rows.

Let indexes_to_drop be an array of positional indexes to drop ([1, 2, 4] in the question).

indexes_to_keep = set(range(df.shape[0])) - set(indexes_to_drop)
df_sliced = df.take(list(indexes_to_keep))

In my case this took 20.5s, while the simple df.drop took 5min 27s and consumed a lot of memory. The resulting DataFrame is the same.

you might consider using the Relative and Absolute positining.

`.container {  
position: relative;  
}  
.tag {     
position: absolute;   
}`  

I have tested it there, also if you want it to change its position use this as its margin:

top: 20px;
left: 10px;

It will place it 20 pixels from top and 10 pixels from left; but leave this one if not necessary.

You can use Boost numeric_cast.

This throws an exception if the source value is out of range of the destination type, but it doesn't detect loss of precision when converting to double.

Whatever function you use, though, you should decide what you want to happen in the case where the value in the size_t is greater than INT_MAX. If you want to detect it use numeric_cast or write your own code to check. If you somehow know that it cannot possibly happen then you could use static_cast to suppress the warning without the cost of a runtime check, but in most cases the cost doesn't matter anyway.

Try to Use JSON.stringify

It really has worked on my machine. But instead of OracleServiceORCL I found OracleServiceXE.

I like to run the following:

git commit -am "message";git push

I had a similar error. The problem had to do with the child and parent table not having the same charset and collation. This can be fixed by appending ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;

CREATE TABLE IF NOT EXISTS `country` (`id` INT(11) NOT NULL AUTO_INCREMENT,...) ENGINE = InnoDB DEFAULT CHARACTER SET = utf8;

... on the SQL statement means that there is some missing code.

Probably the exact details of em.flush() are implementation-dependent. In general anyway, JPA providers like Hibernate can cache the SQL instructions they are supposed to send to the database, often until you actually commit the transaction. For example, you call em.persist(), Hibernate remembers it has to make a database INSERT, but does not actually execute the instruction until you commit the transaction. Afaik, this is mainly done for performance reasons.

In some cases anyway you want the SQL instructions to be executed immediately; generally when you need the result of some side effects, like an autogenerated key, or a database trigger.

What em.flush() does is to empty the internal SQL instructions cache, and execute it immediately to the database.

Bottom line: no harm is done, only you could have a (minor) performance hit since you are overriding the JPA provider decisions as regards the best timing to send SQL instructions to the database.

var size = 0;   
 var darray = new Array();
    function createTable(){
        darray[size] = new Array();
        darray[size][0] = $("#chqdate").val();
        darray[size][1]= $("#chqNo").val();
        darray[size][2] = $("#chqNarration").val() ;
        darray[size][3]= $("#chqAmount").val();
        darray[size][4]= $("#chqMode").val();
    }

increase size var after your function.

The problem is that git by default using the "Linux" crypto backend.

Beginning with Git for Windows 2.14, you can now configure Git to use SChannel, the built-in Windows networking layer as the crypto backend. This means that you it will use the Windows certificate storage mechanism and you do not need to explicitly configure the curl CA storage mechanism: https://msdn.microsoft.com/en-us/library/windows/desktop/aa380123(v=vs.85).aspx

Just execute:

git config --global http.sslbackend schannel

That should helps.

Using schannel is by now the standard setting when installing git for windows, also it is recommended to not checkout repositories by SSH anmore if possible, as https is easier to configure and less likely to be blocked by a firewall it means less chance of failure.

   @Entity @Table(name = "stock", catalog = "mkyongdb",
   uniqueConstraints = @UniqueConstraint(columnNames =
   "STOCK_NAME"),@UniqueConstraint(columnNames = "STOCK_CODE") }) public
   class Stock implements java.io.Serializable {

   }

Unique constraints used only for creating composite key ,which will be unique.It will represent the table as primary key combined as unique.

Use split and map function:

var str = "123, 124, 234,252";
var arr = str.split(",");
arr = arr.map(function (val) { return +val + 1; });

Notice +val - string is casted to a number.

Or shorter:

var str = "123, 124, 234,252";
var arr = str.split(",").map(function (val) { return +val + 1; });

edit 2015.07.29

Today I'd advise against using + operator to cast variable to a number. Instead I'd go with a more explicit but also more readable Number call:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(function (val) {_x000D_
  return Number(val) + 1;_x000D_
});_x000D_
console.log(arr);

edit 2017.03.09

ECMAScript 2015 introduced arrow function so it could be used instead to make the code more concise:

var str = "123, 124, 234,252";_x000D_
var arr = str.split(",").map(val => Number(val) + 1);_x000D_
console.log(arr);

1. You should add L: long i = 12345678910L;.
2. Yes.

BTW: it doesn't have to be an upper case L, but lower case is confused with 1 many times :).

This is how you can go about it:

1. Close Eclipse
2. Download a jar plugin (let's assume its testNG.jar)
3. Copy testNG.jar to a certain folder (say C:\Project\resources\plugins)
4. In your Eclipse installation folder, there is a folder named dropins (could be C:\eclipse\dropins), create a .link file in that folder, (like plugins.link)
5. Open this file with any text editor and enter this one line:
   path=C:/Project/resources/plugins
   
6. Save the file and start Eclipse.

And you are good to go!

Please do not forget to change your backward slashes in your plugins folder path to forward slashes on step 5. I used to forget and it would take my time unnecessarily.

OR do this with jQuery and CSS!

$('input.disabled').attr('ignore','true').css({
    'pointer-events':'none',
     'color': 'gray'
});

This way you make the element look disabled and no pointer events will fire, yet it allows propagation and if submitted you can use the attribute 'ignore' to ignore it.

hostname and uname will give you the name of the host. Then use nslookup to translate that to an IP address.

My experience using Node.js on Windows 7 64-bit in Visual Studio 2013 is that you need to use

setx NODE_ENV development

from a cmd window. AND you have to restart Visual Studio in order for the new value to be recognized.

The set syntax only lasts for the duration of the cmd window in which it is set.

Simple test in Node.js:

console.log('process.env.NODE_ENV = ' + process.env.NODE_ENV);

It returns 'undefined' when using set, and it will return 'development' if using setx and restarting Visual Studio.

I ended up just downloading my pdf using below code

function downloadPdfDocument(fileName){

var req = new XMLHttpRequest();
req.open("POST", "/pdf/" + fileName, true);
req.responseType = "blob";
fileName += "_" + new Date() + ".pdf";

req.onload = function (event) {

    var blob = req.response;

    //for IE
    if (window.navigator && window.navigator.msSaveOrOpenBlob) {
        window.navigator.msSaveOrOpenBlob(blob, fileName);
    } else {

        var link = document.createElement('a');
        link.href = window.URL.createObjectURL(blob);
        link.download = fileName;
        link.click();
    }
};

req.send();

}

I've stumbled upon this while having the same problem. Here is my code. It totally relies on the JS date function, so leap years are handled, and does not compare days based on hours, so it avoids daylight saving issues.

function dateDiff(start, end) {
    let years = 0, months = 0, days = 0;
    // Day diffence. Trick is to use setDate(0) to get the amount of days
    // from the previous month if the end day less than the start day.
    if (end.getDate() < start.getDate()) {
        months = -1;
        let datePtr = new Date(end);
        datePtr.setDate(0);
        days = end.getDate() + (datePtr.getDate() - start.getDate());
    } else {
        days = end.getDate() - start.getDate();
    }

    if (end.getMonth() < start.getMonth() ||
       (end.getMonth() === start.getMonth() && end.getDate() < start.getDate())) {
        years = -1;
        months += end.getMonth() + (12 - start.getMonth());
    } else {
        months += end.getMonth() - start.getMonth();
    }

    years += end.getFullYear() - start.getFullYear();
    console.log(`${years}y ${months}m ${days}d`);
    return [years, months, days];
}

I am using latest swift (2.1) and the answer (Dharmesh Kheni and jungledev) does not work for me. The image color was off (when setting in IB, it was blue and when setting directly in UIButton, it was black). It turns out I could create the same bar item with the following code:

let barButton = UIBarButtonItem(image: UIImage(named: "menu"), landscapeImagePhone: nil, style: .Done, target: self, action: #selector(revealBackClicked))
self.navigationItem.leftBarButtonItem = barButton

ThreeJS r77

var x = event.offsetX == undefined ? event.layerX : event.offsetX;
var y = event.offsetY == undefined ? event.layerY : event.offsetY;

mouse2D.x = ( x / renderer.domElement.width ) * 2 - 1;
mouse2D.y = - ( y / renderer.domElement.height ) * 2 + 1;

After trying many solutions. This worked for me. Might help someone else hence posting. Got it from here

So if you want to programmatically copy google-services.json file from all your variants into your root folder. When you switch to a specific variant here's a solution for you

android {
  applicationVariants.all { variant ->
    copy {
        println "Switches to $variant google-services.json"
        from "src/$variant"
        include "google-services.json"
        into "."
    }
  }
}

There's a caveat to this approach that is you need to have google-service.json file in each of your variants folder here's an example.

OUTDATED: Many modern browsers now have first-class support for crypto operations. See Vitaly Zdanevich's answer below.

The Stanford JS Crypto Library contains an implementation of SHA-256. While crypto in JS isn't really as well-vetted an endeavor as other implementation platforms, this one is at least partially developed by, and to a certain extent sponsored by, Dan Boneh, who is a well-established and trusted name in cryptography, and means that the project has some oversight by someone who actually knows what he's doing. The project is also supported by the NSF.

It's worth pointing out, however...
... that if you hash the password client-side before submitting it, then the hash is the password, and the original password becomes irrelevant. An attacker needs only to intercept the hash in order to impersonate the user, and if that hash is stored unmodified on the server, then the server is storing the true password (the hash) in plain-text.

So your security is now worse because you decided add your own improvements to what was previously a trusted scheme.

"start" is a name of a script, in npm you run scripts like this npm run scriptName, npm start is also a short for npm run start

As for "react-scripts" this is a script related specifically to create-react-app

Just a small improvement for @anubhava's answer: Since special character are limited to the ones in the keyboard, use this for any special character:

^(?=.*?[A-Z])(?=(.*[a-z]){1,})(?=(.*[\d]){1,})(?=(.*[\W]){1,})(?!.*\s).{8,}$

This regex will enforce these rules:

• At least one upper case English letter
• At least one lower case English letter
• At least one digit
• At least one special character
• Minimum eight in length

This is a solution but in form of my story with this problem:

I was almost dead trying all the solution given above(for 3 days ) and nothing worked for me.

I lost all hope.

I contacted my security team regarding this because i was behind a proxy and they told that they had recently updated their security policy.

I scolded them badly for not informing the Developers.

Later they issued a new "cacerts" file which contains all the certificates.

I removed the cacerts file which is present inside %JAVA_HOME%/jre/lib/security and it solved my problem.

So if you are facing this issue it might be from your network team also like this.

Clustered Index

Clustered indexes sort and store the data rows in the table or view based on their key values. These are the columns included in the index definition. There can be only one clustered index per table, because the data rows themselves can be sorted in only one order.

The only time the data rows in a table are stored in sorted order is when the table contains a clustered index. When a table has a clustered index, the table is called a clustered table. If a table has no clustered index, its data rows are stored in an unordered structure called a heap.

Nonclustered

Nonclustered indexes have a structure separate from the data rows. A nonclustered index contains the nonclustered index key values and each key value entry has a pointer to the data row that contains the key value. The pointer from an index row in a nonclustered index to a data row is called a row locator. The structure of the row locator depends on whether the data pages are stored in a heap or a clustered table. For a heap, a row locator is a pointer to the row. For a clustered table, the row locator is the clustered index key.

You can add nonkey columns to the leaf level of the nonclustered index to by-pass existing index key limits, and execute fully covered, indexed, queries. For more information, see Create Indexes with Included Columns. For details about index key limits see Maximum Capacity Specifications for SQL Server.

You can also do:

This works, but there may I'm not sure if it's supported in Django 2.

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

Why not just display it in the user's web browser?

Here's a blog post that should help with escaping ticks in strings.

Here's the simplest method from said post:

The most simple and most used way is to use a single quotation mark with two single >quotation marks in both sides.

SELECT 'test single quote''' from dual;

The output of the above statement would be:

test single quote'

Simply stating you require an additional single quote character to print a single quote >character. That is if you put two single quote characters Oracle will print one. The first >one acts like an escape character.

This is the simplest way to print single quotation marks in Oracle. But it will get >complex when you have to print a set of quotation marks instead of just one. In this >situation the following method works fine. But it requires some more typing labour.

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

Just try beeprint

it prints something like this:

instance(Animal):
    legs: 2,
    name: 'Dog',
    color: 'Spotted',
    smell: 'Alot',
    age: 10,
    kids: 0,

I think is exactly what you need.

server {

    index index.html index.htm;
    server_name test.example.com;

    location / {
        root /web/test.example.com/www;
    }

    location /static {
        root /web/test.example.com;
    }
}

http://nginx.org/r/root

Alright Let's say you have a brand new project, if so you would go to settings.py file and search for TEMPLATES once you found it you just paste this line os.path.join(BASE_DIR, 'template') in 'DIRS' At the end, you should get somethings like this :

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            os.path.join(BASE_DIR, 'template')
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
        },
    },
]

If you want to know where your BASE_DIR directory is located type these 3 simple commands:

python3 manage.py shell

Once you're in the shell :

>>> from django.conf import settings
>>> settings.BASE_DIR

PS: If you named your template folder with another name, you would change it here too.

In my case this very problem was raised by wrong spelling, lower case 'c:' instead of upper case 'C:' in the path. I corrected spelling and problem vanished.

You're going to have to reformat your releases object to be an array of objects. Then you'll be able to sort them the way you're attempting.

Use the strpos function: http://php.net/manual/en/function.strpos.php

$haystack = "foo bar baz";
$needle   = "bar";

if( strpos( $haystack, $needle ) !== false) {
    echo "\"bar\" exists in the haystack variable";
}

In your case:

if( strpos( $a, 'some text' ) !== false ) echo 'text';

Note that my use of the !== operator (instead of != false or == true or even just if( strpos( ... ) ) {) is because of the "truthy"/"falsy" nature of PHP's handling of the return value of strpos.

As of PHP 8.0.0 you can now use str_contains

<?php
    if (str_contains('abc', '')) {
        echo "Checking the existence of the empty string will always 
        return true";
    }

//More Efficiently
public class Multiples {
    public static void main(String[]args) {

        int j = 5;

        System.out.println(j % 4 == 0);

    }
}

Since I stumbled on this answer, and it greatly helped me, but I found a minor syntactic issue, I felt I should save others possible frustration. The triple quoted string works for this scenario as described, but note that if the " you want in the string occurs at the end of the string itself:

somestr = """This is a string with a special need to have a " in it at the end""""

You will hit an error at execution because the """" (4) quotes in a row confuses the string reader, as it thinks it has hit the end of the string already and then finds a random " out there. You can validate this by inserting a space into the 4 quotes like so: " """ and it will not have the error.

In this special case you will need to either use:

somestr = 'This.....at the end"'

or use the method described above of building multiple strings with mixed " and ' and then concatenating them after the fact.

A different approach, just for kicks:

Console.WriteLine(string.Join("\t", list));

For security reasons, you can only get the url for as long as the contents of the iframe, and the referencing javascript, are served from the same domain. As long as that is true, something like this will work:

document.getElementById("iframe_id").contentWindow.location.href

If the two domains are mismatched, you'll run into cross site reference scripting security restrictions.

yo need create the user "pma" in mysql or change this lines(user and password for mysql):

/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = 'pma'; 
$cfg['Servers'][$i]['controlpass'] = '';

Linux: /etc/phpmyadmin/config.inc.php

function(e){ e.preventDefault();

and its opposite

function(e){ return true; }

cheers!

As a workaround I've been returning the last object in the array that you get back from the function... It is not a great solution, but it's better than nothing:

someFunction {
   $a = "hello"
   "Function is running"
   return $a
}

$b = someFunction
$b = $b[($b.count - 1)]  # Or
$b = $b[-1]              # Simpler

All in all, a more one-lineish way of writing the same thing could be:

$b = (someFunction $someParameter $andAnotherOne)[-1]

This advice was great. I had the same problem, but my solution was different, because I was so stupid, that I have renamed directory where XAMPP was located and since I had installed a lot of another programs I couldn't rename it back.

In my case there was original directory C:\Programs\Xampp and renamed it to C:\PROGRAMS_\Xampp and that was the mistake.

The solution was to find all references on C:\Programs and rename them C:\PROGRAMS_ in the XAMPP directory, because for some reason during the installation it writes absolute paths, not relative. Of course, there are some references in the registry too.

chmod 400 mykey.pem

ssh -i mykey.pem [email protected]

Will connect you over ssh using a .pem file to any server.

You could move the common parts to another configuration file and include from both server contexts. This should work:

server {
  listen 80;
  server_name server1.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

server {
  listen 80;
  server_name another-one.example;
  ...
  include /etc/nginx/include.d/your-common-stuff.conf;
}

Edit: Here's an example that's actually copied from my running server. I configure my basic server settings in /etc/nginx/sites-enabled (normal stuff for nginx on Ubuntu/Debian). For example, my main server bunkus.org's configuration file is /etc/nginx/sites-enabled and it looks like this:

server {
  listen   80 default_server;
  listen   [2a01:4f8:120:3105::101:1]:80 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-80;
}

server {
  listen   443 default_server;
  listen   [2a01:4f8:120:3105::101:1]:443 default_server;

  include /etc/nginx/include.d/all-common;
  include /etc/nginx/include.d/ssl-common;
  include /etc/nginx/include.d/bunkus.org-common;
  include /etc/nginx/include.d/bunkus.org-443;
}

As an example here's the /etc/nginx/include.d/all-common file that's included from both server contexts:

index index.html index.htm index.php .dirindex.php;
try_files $uri $uri/ =404;

location ~ /\.ht {
  deny all;
}

location = /favicon.ico {
  log_not_found off;
  access_log off;
}

location ~ /(README|ChangeLog)$ {
  types { }
  default_type text/plain;
}

I have seen all answers. I want tell most robust way now a day. That will make you communicate between Activity - Service - Dialog - Fragments (Everything).

EventBus

This lib which i am using in my projects has great features related to messaging.

EventBus in 3 steps

1. Define events:

   public static class MessageEvent { /* Additional fields if needed */ }

2. Prepare subscribers:

Declare and annotate your subscribing method, optionally specify a thread mode:

@Subscribe(threadMode = ThreadMode.MAIN) 
public void onMessageEvent(MessageEvent event) {/* Do something */};

Register and unregister your subscriber. For example on Android, activities and fragments should usually register according to their life cycle:

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

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

3. Post events:

   EventBus.getDefault().post(new MessageEvent());

Just add this dependency in your app level gradle

compile 'org.greenrobot:eventbus:3.1.1'

If should be if. Your program should look like this:

answer = raw_input("Is the information correct? Enter Y for yes or N for no")
if answer.upper() == 'Y':
    print("this will do the calculation")
else:
    exit()

Note also that the indentation is important, because it marks a block in Python.

As of today, there is no support on this function. However, I found a little hack on this one.

 imageView.setImageResource(R.drawable.ic_star_black_48dp);
 imageView.setTag(R.drawable.ic_star_black_48dp);

So if you want to get the ID of the view, just get it's tag.

if (imageView.getTag() != null) {
   int resourceID = (int) imageView.getTag();

   //
   // drawable id.
   //   
}

The only illegal characters are &, < and > (as well as " or ' in attributes, depending on which character is used to delimit the attribute value: attr="must use " here, ' is allowed" and attr='must use ' here, " is allowed').

They're escaped using XML entities, in this case you want & for &.

Really, though, you should use a tool or library that writes XML for you and abstracts this kind of thing away for you so you don't have to worry about it.

Neither of these options is correct. You're trying to implement a synchronous interface asynchronously. Don't do that. The problem is that when DoOperation() returns, the operation won't be complete yet. Worse, if an exception happens during the operation (which is very common with IO operations), the user won't have a chance to deal with that exception.

What you need to do is to modify the interface, so that it is asynchronous:

interface IIO
{
    Task DoOperationAsync(); // note: no async here
}

class IOImplementation : IIO
{
    public async Task DoOperationAsync()
    {
        // perform the operation here
    }
}

This way, the user will see that the operation is async and they will be able to await it. This also pretty much forces the users of your code to switch to async, but that's unavoidable.

Also, I assume using StartNew() in your implementation is just an example, you shouldn't need that to implement asynchronous IO. (And new Task() is even worse, that won't even work, because you don't Start() the Task.)

If it only happens on mapped drives it might be bug https://bitbucket.org/tortoisehg/thg/issue/889/cant-commit-file-over-network-share. Using UNC path instead of drive letter seems to sidestep the issue.

Do not use forward slashes at the beginning of path components, except when refering to the root directory:

os.path.join('/home/build/test/sandboxes', todaystr, 'new_sandbox')

see also: http://docs.python.org/library/os.path.html#os.path.join

Here is my suggested validation:

var isValid = false;

// Check whether this entered value is numeric.
function checkNumeric() {
    var numericVal = document.getElementById("txt_numeric").value;

    if(isNaN(numericVal) || numericVal == "" || numericVal == null || numericVal.indexOf(' ') >= 0) {
        alert("Please, enter a numeric value!");
        isValid = false;
    } else {
        isValid = true;
    }
}

I have created a library to batch delete or update records with a round trip on EF Core 5.

Sample code as follows:

await ctx.DeleteRangeAsync(b => b.Price > n || b.AuthorName == "zack yang");

await ctx.BatchUpdate()
.Set(b => b.Price, b => b.Price + 3)
.Set(b=>b.AuthorName,b=>b.Title.Substring(3,2)+b.AuthorName.ToUpper())
.Set(b => b.PubTime, b => DateTime.Now)
.Where(b => b.Id > n || b.AuthorName.StartsWith("Zack"))
.ExecuteAsync();

Github repository: https://github.com/yangzhongke/Zack.EFCore.Batch Report: https://www.reddit.com/r/dotnetcore/comments/k1esra/how_to_batch_delete_or_update_in_entity_framework/

I wrote this snippet, that I've been using for handling this exact case.

It's in plain javascript, making it also suitable in cases like with bootsrap5 without jQuery.

<script type='text/javascript'>
    window.onhashchange=hashTriggerTab;
    window.onload=hashTriggerTab;
    
    function hashTriggerTab(){
        var current_hash=window.location.hash;
        if(current_hash.substring(0,1)=='#')current_hash=current_hash.substring(1);
        if(current_hash!=''){
            var trigger=document.querySelector('.nav-tabs a[href="#'+current_hash+'"]');
            if(trigger)trigger.click();
        }
    }
</script>

With that in place, you could link both on the same page, like:

<a href='#tabId'>Link Any Tab</a>

Or from external page like:

<a href='newpage.php#tabId'>Link From External</a>

In your Eclipse installation directory you should be able to find the file eclipse.ini. Open it and find the -vmargs section. Adjust the value of:

-Xmx1024m

In this example it is set to 1GB.

from Python version 2.6 you can do this:

def format_builtin(n):
    return format(n, ',')

For Python versions < 2.6 and just for your information, here are 2 manual solutions, they turn floats to ints but negative numbers work correctly:

def format_number_using_lists(number):
    string = '%d' % number
    result_list = list(string)
    indexes = range(len(string))
    for index in indexes[::-3][1:]:
        if result_list[index] != '-':
            result_list.insert(index+1, ',')
    return ''.join(result_list)

few things to notice here:

• this line: string = '%d' % number beautifully converts a number to a string, it supports negatives and it drops fractions from floats, making them ints;
• this slice indexes[::-3] returns each third item starting from the end, so I used another slice [1:] to remove the very last item cuz I don't need a comma after the last number;
• this conditional if l[index] != '-' is being used to support negative numbers, do not insert a comma after the minus sign.

And a more hardcore version:

def format_number_using_generators_and_list_comprehensions(number):
    string = '%d' % number
    generator = reversed( 
        [
            value+',' if (index!=0 and value!='-' and index%3==0) else value
            for index,value in enumerate(reversed(string))
        ]
    )
    return ''.join(generator)

TRAC. Open source, Python-based

Basically, you need to catch the OperationCanceledException and check the state of the cancellation token that was passed to SendAsync (or GetAsync, or whatever HttpClient method you're using):

• if it was canceled (IsCancellationRequested is true), it means the request really was canceled
• if not, it means the request timed out

Of course, this isn't very convenient... it would be better to receive a TimeoutException in case of timeout. I propose a solution here based on a custom HTTP message handler: Better timeout handling with HttpClient

the function Position in funprog {base} also does the job. It allows you to pass an arbitrary function, and returns the first or last match.

Position(f, x, right = FALSE, nomatch = NA_integer)

You can use rabbitmqctl eval as below:

rabbitmqctl eval 'IfUnused = false, IfEmpty = true, MatchRegex = 
<<"^prefix-">>, [rabbit_amqqueue:delete(Q, IfUnused, IfEmpty) || Q <- 
rabbit_amqqueue:list(), re:run(element(4, element(2, Q)), MatchRegex) 
=/= nomatch ].' 

The above will delete all empty queues in all vhosts that have a name beginning with "prefix-". You can edit the variables IfUnused, IfEmpty, and MatchRegex as per your requirement.

Found the chrome Options class in the Selenium source code.

Usage to create a Chrome driver instance:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
chrome_options = Options()
chrome_options.add_argument("--disable-extensions")
driver = webdriver.Chrome(chrome_options=chrome_options)

the disabled attributes value is actally not considered.. usually if you have noticed the attribute is set as disabled="disabled" the "disabled" here is not necessary persay.. thus the best thing to do is to remove the attribute.

element.removeAttribute("disabled");     

also you could do

element.disabled=false;

Validation (HTML5): Attribute 'name' is not a valid attribute of element 'label'.

I had the same issue. The reason was the corporate proxy issue. Solution was to set the proxy setting as @rsp says.

npm config set proxy http://example.com:8080
npm config set https-proxy http://example.com:8080

But later I face the same issue. This time reason was my password contains a special character.

In this command you can’t provide a password with special character

. So solution is to provide percentage encoded special character in the password.

For example # has to provide as %23

To deserialize the response need to use HashMap:

String resp = ...//String output from your source

Gson gson = new GsonBuilder().create();
gson.fromJson(resp,TheResponse.class);

class TheResponse{
 HashMap<String,Song> songs;
}

class Song{
  String id;
  String pos;
}

If you want the word "Hello" to print in a column that's 40 characters wide, with spaces padding the left, use the following.

char *ptr = "Hello";
printf("%40s\n", ptr);

That will give you 35 spaces, then the word "Hello". This is how you format stuff when you know how wide you want the column, but the data changes (well, it's one way you can do it).

If you know you want exactly 40 spaces then some text, just save the 40 spaces in a constant and print them. If you need to print multiple lines, either use multiple printf statements like the one above, or do it in a loop, changing the value of ptr each time.

I could use the following code. Thanks everyone.

int intID = 5;
DataTable Dt = MyFuctions.GetData();
Dt.PrimaryKey = new DataColumn[] { Dt.Columns["ID"] };
DataRow Drw = Dt.Rows.Find(intID);
if (Drw != null) Dt.Rows.Remove(Drw);

var _href = $("a.directions-link").attr("href");
$("a.directions-link").attr("href", _href + '&saddr=50.1234567,-50.03452');

To loop with each()

$("a.directions-link").each(function() {
   var $this = $(this);       
   var _href = $this.attr("href"); 
   $this.attr("href", _href + '&saddr=50.1234567,-50.03452');
});

Sometimes if you are using some simple login info like this: username: 'admin' and pass: 'admin', the hosting is seeing you as a potential Brute Force Attack through WP login file, and blocks you IP address or that particularly file.

I had that issue with ixwebhosting and just got that info from their support guy. They must unban your IP in this situation. And you must change your WP admin login info to something more secure.

That solved my problem.

There is a function in PHP specifically designed for that purpose, str_word_count(). By default it does not take into account the numbers and multibyte characters, but they can be added as a list of additional characters in the charlist parameter. Charlist parameter also accepts a range of characters as in the example.

One benefit of this function over explode() is that the punctuation marks, spaces and new lines are avoided.

$str = "1st example:
        Alte Füchse gehen schwer in die Falle.    ";

print_r( str_word_count( $str, 1, '1..9ü' ) );

/* output:
Array
(
    [0] => 1st
    [1] => example
    [2] => Alte
    [3] => Füchse
    [4] => gehen
    [5] => schwer
    [6] => in
    [7] => die
    [8] => Falle
)
*/

Your custom class can implement the "Comparable" interface, which requires an implementation of the CompareTo method. In the CompareTo method, you can then define what it means that an object is less than or more than the other object. So in your example, it can look something like this:

public class MyCustomClass implements Comparable<MyCustomClass>{

..........

 @Override
public int compareTo(MyCustomClass a) {
    if(this.getStartDate().before(a.getStartDate())){
        return -1;
    }else if(a.getStartDate().before(this.getStartDate())){
        return 1;
    }else {
        return 0;
    }
}

A negative number indicates that this is smaller than the object being compared to. A positive number indicates that this is larger than the compared to object and a Zero means that the objects are equal.

You can then use the collections.sort(myList) to sort your list without having to feed in a comparator. This method also has the advantage of having things sorted automatically if you use a sorted collection data structures like a TreeSet or a TreeMap.

You can check this article if you would like to read more about the Comparable interface (disclosure: I am the author ;) ) https://nullbeans.com/the-java-comparable-interface-automatic-sort-of-collections/

footer {
  margin-top:calc(5% + 60px);
}

This works fine

You can give like this

public static function getAll()
{

    return $posts = $this->all()->take(2)->get();

}

And when you call statically inside your controller function also..

In command line prompt:

set __COMPAT_LAYER=RUNASINVOKER
SystemPropertiesAdvanced.exe

Now you can set user environment variables.

when you invoke a function , it is termed 'calling' a function . For eg , suppose you've defined a function that finds the average of two numbers like this-

def avgg(a,b) :
        return (a+b)/2;

now, to call the function , you do like this .

x=avgg(4,6)
print x

value of x will be 5 .

Most likely it means that the open didn't fail.

When Perl opens a file, it checks whether or not the file is a TTY (so that it can answer the -T $fh filetest operator) by issuing the TCGETS ioctl against it. If the file is a regular file and not a tty, the ioctl fails and sets errno to ENOTTY (string value: "Inappropriate ioctl for device"). As ysth says, the most common reason for seeing an unexpected value in $! is checking it when it's not valid -- that is, anywhere other than immediately after a syscall failed, so testing the result codes of your operations is critically important.

If open actually did return false for you, and you found ENOTTY in $! then I would consider this a small bug (giving a useless value of $!) but I would also be very curious as to how it happened. Code and/or truss output would be nifty.

I had the same issue, and spent quite a bit of time trying to track down the solution. I had Anonymous Authentication set up at two different levels with two different users. Make sure that you're not overwriting your set up at a lower level.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

GitHub: Permission denied (publickey). fatal: The remote end hung up unexpectedly which links here in the accepted answer (from the original poster, no less): http://help.github.com/linux-set-up-git/

I've seen this behavior today when the

   <service name="A.B.C.D" behaviorConfiguration="returnFaults">
        <endpoint contract="A.B.C.ID" binding="basicHttpBinding" address=""/>
    </service>

was missing from the web.config. The service.svc file was there and got served. It took a while to realize that the problem was not in the binding configuration it self...

I think you need to run that .msi to install the dlls. After I ran that .msi I can go to (VS 2012) Add References > Assemblies > Extensions and all of the Microsoft.Office.Interop dlls are there.

On my computer the dlls are found in "c:\Program Files(x86)\Microsoft Visual Studio 12.0\Visual Studio Tools for Office\PIA" so you could check in a similar/equivalent directory on yours just to make sure they're not there?

You can't. They simply do not work that way. A drop down menu must have one of its options selected at all times.

You could (although I don't recommend it) watch for a change event and then use JS to delete the first option if it is blank.

The reason people often suggest writing

VAR=value
export VAR

instead of the shorter

export VAR=value

is that the longer form works in more different shells than the short form. If you know you're dealing with bash, either works fine, of course.

Werkzeug/Flask as already parsed everything for you. No need to do the same work again with urlparse:

from flask import request

@app.route('/')
@app.route('/data')
def data():
    query_string = request.query_string  ## There is it
    return render_template("data.html")

The full documentation for the request and response objects is in Werkzeug: http://werkzeug.pocoo.org/docs/wrappers/

In regards to Gordon M's answer above, the 1st and 2nd parameter in mysqli_real_escape_string () call should be swapped for the newer php versions, according to: http://php.net/manual/en/mysqli.real-escape-string.php

Using html5 I cooked up this one:

Some where on the page:

<h2 id="heading" data-activetab="@ViewBag.activetab">Some random text</h2>

The viewbag should just contain the id for the page/element eg.: "testing"

I created a site.js and added the scrip on the page:

/// <reference path="../jquery-2.1.0.js" />
$(document).ready(
  function() {
    var setactive = $("#heading").data("activetab");
    var a = $('#' + setactive).addClass("active");
  }
)

Now all you have to do is to add your id's to your navbar. Eg.:

<ul class="nav navbar-nav">
  <li **id="testing" **>
    @Html.ActionLink("Lalala", "MyAction", "MyController")
  </li>
</ul>

All hail the data attribute :)

I am lost in all these samples but today I needed to load an external .js from my main .js and I did this:

document.write("<script src='https://www.google.com/recaptcha/api.js'></script>");

This may be a sideways answer, but if you download Virtuemart (A Joomla component), it has a countries table and all the related states all set up for you included in the installation SQL. They're called jos_virtuemart_countries and jos_virtuemart_states. It also includes the 2 and 3 character country codes. I'd attach it to my answer, but don't see a way of doing it.

You can reload using /etc/init.d/nginx reload and sudo service nginx reload

If nginx -t throws some error then it won't reload

so use && to run both at a same time

like

nginx -t && /etc/init.d/nginx reload

You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

I have faced the similar issue on my website hosted on IIS. This issue generally because of IIS Application pool settings. As application pool recycle after some time that caused the issue for me.

Following steps help me to fix the issue:

1. Open App pool of you website on IIS.
2. Go to Advance settings on right hand pane.
3. Scroll down to Process Model
4. Change Idle Time-out minutes to 20 or number of minutes you don't want to recycle your App pool.

Then try again . It will solve your issue.

Hashmaps can only use classes, not primitives. This page from programmerinterview.com might be of use in guiding you to finding the answer. To be honest, I haven't figured out the answer to this problem in detail myself.

Calculates the largest prime factor of a number using recursion in C++. The working of the code is explained below:

int getLargestPrime(int number) {
    int factor = number; // assumes that the largest prime factor is the number itself
    for (int i = 2; (i*i) <= number; i++) { // iterates to the square root of the number till it finds the first(smallest) factor
        if (number % i == 0) { // checks if the current number(i) is a factor
            factor = max(i, number / i); // stores the larger number among the factors
            break; // breaks the loop on when a factor is found
        }
    }
    if (factor == number) // base case of recursion
        return number;
    return getLargestPrime(factor); // recursively calls itself
}

OK, so I don't really know what the problem was, but I simply fixed it by navigating to here http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and installing 8u74 instead of 8u73 which is what I was prompted to do when I would go to "download latest version" in Java. So changing the versions is what did it in the end. Eclipse launched fine, now. Thanks for everyone's help!

edit: Apr 2018- Now is 8u161 and 8u162 (Just need one, I used 8u162 and it worked.)

And if you want to vary the speed and include callbacks simply add them like this :

        jQuery.fn.extend({
            slideRightShow: function(speed,callback) {
                return this.each(function() {
                    $(this).show('slide', {direction: 'right'}, speed, callback);
                });
            },
            slideLeftHide: function(speed,callback) {
                return this.each(function() {
                    $(this).hide('slide', {direction: 'left'}, speed, callback);
                });
            },
            slideRightHide: function(speed,callback) {
                return this.each(function() {  
                    $(this).hide('slide', {direction: 'right'}, speed, callback);
                });
            },
            slideLeftShow: function(speed,callback) {
                return this.each(function() {
                    $(this).show('slide', {direction: 'left'}, speed, callback);
                });
            }
        });

There's a description of how to do this at Resize a column in a PostgreSQL table without changing data. You have to hack the database catalog data. The only way to do this officially is with ALTER TABLE, and as you've noted that change will lock and rewrite the entire table while it's running.

Make sure you read the Character Types section of the docs before changing this. All sorts of weird cases to be aware of here. The length check is done when values are stored into the rows. If you hack a lower limit in there, that will not reduce the size of existing values at all. You would be wise to do a scan over the whole table looking for rows where the length of the field is >40 characters after making the change. You'll need to figure out how to truncate those manually--so you're back some locks just on oversize ones--because if someone tries to update anything on that row it's going to reject it as too big now, at the point it goes to store the new version of the row. Hilarity ensues for the user.

VARCHAR is a terrible type that exists in PostgreSQL only to comply with its associated terrible part of the SQL standard. If you don't care about multi-database compatibility, consider storing your data as TEXT and add a constraint to limits its length. Constraints you can change around without this table lock/rewrite problem, and they can do more integrity checking than just the weak length check.

map[key] = value is provided for easier syntax. It is easier to read and write.

The reason for which you need to have default constructor is that map[key] is evaluated before assignment. If key wasn't present in map, new one is created (with default constructor) and reference to it is returned from operator[].

I think it gives the error because of the underscore symbol.

Note : underscore symbol should not be written directly, you have to write like as \_.

So fix these kind special symbol errors.

If you paste

A.do() {
  if (condition1) {

  }
}

in case you are interested in reading some data from a .txt file and only extract few columns of that file into a new .txt file with a customized header, the following code might be useful:

# input some data from 2 different .txt files:
civit_gps <- read.csv(file="/path2/gpsFile.csv",head=TRUE,sep=",")
civit_cam <- read.csv(file="/path2/cameraFile.txt",head=TRUE,sep=",")

# assign the name for the output file:
seqName <- "seq1_data.txt"

#=========================================================
# Extract data from imported files
#=========================================================
# From Camera:
frame_idx <- civit_cam$X.frame
qx        <- civit_cam$q.x.rad.
qy        <- civit_cam$q.y.rad.
qz        <- civit_cam$q.z.rad.
qw        <- civit_cam$q.w

# From GPS:
gpsT      <- civit_gps$X.gpsTime.sec.
latitude  <- civit_gps$Latitude.deg.
longitude <- civit_gps$Longitude.deg.
altitude  <- civit_gps$H.Ell.m.
heading   <- civit_gps$Heading.deg.
pitch     <- civit_gps$pitch.deg.
roll      <- civit_gps$roll.deg.
gpsTime_corr <- civit_gps[frame_idx,1]

#=========================================================
# Export new data into the output txt file
#=========================================================
myData <- data.frame(c(gpsTime_corr),
                     c(frame_idx),
                     c(qx),
                     c(qy),
                     c(qz),
                     c(qw))
# Write :
cat("#GPSTime,frameIdx,qx,qy,qz,qw\n", file=seqName)
write.table(myData, file = seqName,row.names=FALSE,col.names=FALSE,append=TRUE,sep = ",")

Of course, you should modify this sample script based on your own application.

In your controller, render the new action from your create action if validation fails, with an instance variable, @car populated from the user input (i.e., the params hash). Then, in your view, add a logic check (either an if block around the form or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car is set.

If you need to you can also add an image that contains the arrow as part of the background.

In Laravel 5.5 is very simple, if you are using CRUD route system.

Go to app/http/controllers/RegisterController there is namespace: Illuminate\Foundation\Auth\RegistersUser

You need to go to the RegistersUser: Illuminate\Foundation\Auth\RegistersUser

There is the method call showRegistrationForm change this: return view('auth.login'); for this: return redirect()->route('auth.login'); and remove from you blade page route call register. It may look like that:

 <li role="presentation">
     <a class="nav-link" href="{{ route('register') }}">Register</a>
 </li> 

this work for me:

HashMap<String, String> meMap=new HashMap<String, String>();
meMap.put("Color1","Red");
meMap.put("Color2","Blue");
meMap.put("Color3","Green");
meMap.put("Color4","White");

Iterator iterator = meMap.keySet().iterator();
while( iterator. hasNext() )
{
    Toast.makeText(getBaseContext(), meMap.get(iterator.next().toString()), 
    Toast.LENGTH_SHORT).show();
}

add these code into the top of your script to solve problem

@set_magic_quotes_runtime(false);
ini_set('magic_quotes_runtime', 0);

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

As far as I know, there are 2 standard ways you can do that.

1. @Input

Whenever the data in the parent changes, the child gets notified about this in the ngOnChanges method. The child can act on it. This is the standard way of interacting with a child.

Parent-Component
public inputToChild: Object;

Parent-HTML
<child [data]="inputToChild"> </child>       

Child-Component: @Input() data;

ngOnChanges(changes: { [property: string]: SimpleChange }){
   // Extract changes to the input property by its name
   let change: SimpleChange = changes['data']; 
// Whenever the data in the parent changes, this method gets triggered. You 
// can act on the changes here. You will have both the previous value and the 
// current value here.
}

2. Shared service concept

Creating a service and using an observable in the shared service. The child subscribes to it and whenever there is a change, the child will be notified. This is also a popular method. When you want to send something other than the data you pass as the input, this can be used.

SharedService
subject: Subject<Object>;

Parent-Component
constructor(sharedService: SharedService)
this.sharedService.subject.next(data);

Child-Component
constructor(sharedService: SharedService)
this.sharedService.subject.subscribe((data)=>{

// Whenever the parent emits using the next method, you can receive the data 
in here and act on it.})

Different Python modules to read wav:

There is at least these following libraries to read wave audio files:

• SoundFile
• scipy.io.wavfile (from scipy)
• wave (to read streams. Included in Python 2 and 3)
• scikits.audiolab (unmaintained since 2010)
• sounddevice (play and record sounds, good for streams and real-time)
• pyglet
• librosa (music and audio analysis)
• madmom (strong focus on music information retrieval (MIR) tasks)

The most simple example:

This is a simple example with SoundFile:

import soundfile as sf
data, samplerate = sf.read('existing_file.wav') 

Format of the output:

Warning, the data are not always in the same format, that depends on the library. For instance:

from scikits import audiolab
from scipy.io import wavfile
from sys import argv
for filepath in argv[1:]:
    x, fs, nb_bits = audiolab.wavread(filepath)
    print('Reading with scikits.audiolab.wavread:', x)
    fs, x = wavfile.read(filepath)
    print('Reading with scipy.io.wavfile.read:', x)

Output:

Reading with scikits.audiolab.wavread: [ 0.          0.          0.         ..., -0.00097656 -0.00079346 -0.00097656]
Reading with scipy.io.wavfile.read: [  0   0   0 ..., -32 -26 -32]

SoundFile and Audiolab return floats between -1 and 1 (as matab does, that is the convention for audio signals). Scipy and wave return integers, which you can convert to floats according to the number of bits of encoding, for example:

from scipy.io.wavfile import read as wavread
samplerate, x = wavread(audiofilename)  # x is a numpy array of integers, representing the samples 
# scale to -1.0 -- 1.0
if x.dtype == 'int16':
    nb_bits = 16  # -> 16-bit wav files
elif x.dtype == 'int32':
    nb_bits = 32  # -> 32-bit wav files
max_nb_bit = float(2 ** (nb_bits - 1))
samples = x / (max_nb_bit + 1)  # samples is a numpy array of floats representing the samples 

If you can't be bothered to remember what argument position is for what and you want do something like a ruby argument hash. You can use one argument to pass in a string and then regex that string into an options hash.

namespace :dummy_data do
  desc "Tests options hash like arguments"
  task :test, [:options] => :environment do |t, args|
    arg_options = args[:options] || '' # nil catch incase no options are provided
    two_d_array = arg_options.scan(/\W*(\w*): (\w*)\W*/)
    puts two_d_array.to_s + ' # options are regexed into a 2d array'
    string_key_hash = two_d_array.to_h
    puts string_key_hash.to_s + ' # options are in a hash with keys as strings'
    options = two_d_array.map {|p| [p[0].to_sym, p[1]]}.to_h
    puts options.to_s + ' # options are in a hash with symbols'
    default_options = {users: '50', friends: '25', colour: 'red', name: 'tom'}
    options = default_options.merge(options)
    puts options.to_s + ' # default option values are merged into options'
  end
end

And on the command line you get.

$ rake dummy_data:test["users: 100 friends: 50 colour: red"]
[["users", "100"], ["friends", "50"], ["colour", "red"]] # options are regexed into a 2d array
{"users"=>"100", "friends"=>"50", "colour"=>"red"} # options are in a hash with keys as strings
{:users=>"100", :friends=>"50", :colour=>"red"} # options are in a hash with symbols
{:users=>"100", :friends=>"50", :colour=>"red", :name=>"tom"} # default option values are merged into options

here is an example for geting a refrence for the root View of a layout , inflating it and using it with setContentView(View view)

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    LayoutInflater li=getLayoutInflater();
    View rootView=li.inflate(R.layout.activity_main,null);
    setContentView(rootView);


}
