I know it's not the answer you want, but IMO the proposed solutions are not good (and your own way is). Why? Because they depend on the application state. In JavaFX, a control, a scene and a stage do not depend on each other. This means a control can live without being added to a scene and a scene can exist without being attached to a stage. And then, at a time instant t1, control can get attached to a scene and at instant t2, that scene can be added to a stage (and that explains why they are observable properties of each other).

So the approach that suggests getting the controller reference and invoking a method, passing the stage to it adds a state to your application. This means you need to invoke that method at the right moment, just after the stage is created. In other words, you need to follow an order now: 1- Create the stage 2- Pass this created stage to the controller via a method.

You cannot (or should not) change this order in this approach. So you lost statelessness. And in software, generally, state is evil. Ideally, methods should not require any call order.

So what is the right solution? There are two alternatives:

1- Your approach, in the controller listening properties to get the stage. I think this is the right approach. Like this:

pane.sceneProperty().addListener((observableScene, oldScene, newScene) -> {
    if (oldScene == null && newScene != null) {
        // scene is set for the first time. Now its the time to listen stage changes.
        newScene.windowProperty().addListener((observableWindow, oldWindow, newWindow) -> {
            if (oldWindow == null && newWindow != null) {
                // stage is set. now is the right time to do whatever we need to the stage in the controller.
                ((Stage) newWindow).maximizedProperty().addListener((a, b, c) -> {
                    if (c) {
                        System.out.println("I am maximized!");
                    }
                });
            }
        });
    }
});

2- You do what you need to do where you create the Stage (and that's not what you want):

Stage stage = new Stage();
stage.maximizedProperty().addListener((a, b, c) -> {
            if (c) {
                System.out.println("I am maximized!");
            }
        });
stage.setScene(someScene);
...

Toggle icons in runtime:

In addition to the responses here, I found that once you have assigned an Icon to your application by the first time you cannot toggle it by just adding a new icon to your stage (this would be helpful if you need to toggle the icon of your app from on/off enabled/disabled).

To set a new icon during run time use the getIcons().remove(0) before trying to add a new icon, where 0 is the index of the icon you want to override like is shown here:

//Setting icon by first time (You can do this on your start method).
stage.getIcons().add(new Image(getClass().getResourceAsStream("enabled.png")));

//Overriding app icon with a new status (This can be in another method)
stage.getIcons().remove(0);
stage.getIcons().add(new Image(getClass().getResourceAsStream("disabled.png")));

To access the stage from other methods or classes you can create a new static field for stage in you main class so can access it from out of the start() method by encapsulating in on a static method that you can access from anywhere in your app.

public class MainApp extends Application {
    private static Stage stage;
    public static Stage getStage() { return stage; }

    @Override public void start(Stage primaryStage) {
        stage = primaryStage
        stage.getIcons().add(new Image(getClass().getResourceAsStream("enabled.png")));
    }
}

public class AnotherClass {
    public void setStageTitle(String newTitle) {
        MainApp.getStage().setTitle(newTitle);
        MainApp.getStage().getIcons().remove(0);
        MainApp.getStage().getIcons().add(new Image(getClass().getResourceAsStream("disabled.png")));
    }
}

I had faced he similar problem however it got resolved once i renamed the file , so i would suggest that you should

"Just rename the file"

As iEamin said in his answer, HTML 5 does now support this. The link he gave, http://www.html5rocks.com/en/tutorials/file/dndfiles/ , is excellent. Here is a minimal sample based on the samples at that site, but see that site for more thorough examples.

Add an onchange event listener to your HTML:

<input type="file" onchange="onFileSelected(event)">

Make an image tag with an id (I'm specifying height=200 to make sure the image isn't too huge onscreen):

<img id="myimage" height="200">

Here is the JavaScript of the onchange event listener. It takes the File object that was passed as event.target.files[0], constructs a FileReader to read its contents, and sets up a new event listener to assign the resulting data: URL to the img tag:

function onFileSelected(event) {
  var selectedFile = event.target.files[0];
  var reader = new FileReader();

  var imgtag = document.getElementById("myimage");
  imgtag.title = selectedFile.name;

  reader.onload = function(event) {
    imgtag.src = event.target.result;
  };

  reader.readAsDataURL(selectedFile);
}

I think the C++11 approach would be more like this now.

#include <string>
#include <iostream>
#include <functional>

template<typename T>
class LambdaSetter {
public:
    LambdaSetter() :
        getter([&]() -> T { return m_value; }),
        setter([&](T value) { m_value = value; }),
        m_value()
    {}

    T operator()() { return getter(); }
    void operator()(T value) { setter(value); }

    LambdaSetter operator=(T rhs)
    {
        setter(rhs);
        return *this;
    }

    T operator=(LambdaSetter rhs)
    {
        return rhs.getter();
    }

    operator T()
    { 
        return getter();
    }


    void SetGetter(std::function<T()> func) { getter = func; }
    void SetSetter(std::function<void(T)> func) { setter = func; }

    T& GetRawData() { return m_value; }

private:
    T m_value;
    std::function<const T()> getter;
    std::function<void(T)> setter;

    template <typename TT>
    friend std::ostream & operator<<(std::ostream &os, const LambdaSetter<TT>& p);

    template <typename TT>
    friend std::istream & operator>>(std::istream &is, const LambdaSetter<TT>& p);
};

template <typename T>
std::ostream & operator<<(std::ostream &os, const LambdaSetter<T>& p)
{
    os << p.getter();
    return os;
}

template <typename TT>
std::istream & operator>>(std::istream &is, const LambdaSetter<TT>& p)
{
    TT value;
    is >> value;
    p.setter(value);
    return is;
}


class foo {
public:
    foo()
    {
        myString.SetGetter([&]() -> std::string { 
            myString.GetRawData() = "Hello";
            return myString.GetRawData();
        });
        myString2.SetSetter([&](std::string value) -> void { 
            myString2.GetRawData() = (value + "!"); 
        });
    }


    LambdaSetter<std::string> myString;
    LambdaSetter<std::string> myString2;
};

int _tmain(int argc, _TCHAR* argv[])
{
    foo f;
    std::string hi = f.myString;

    f.myString2 = "world";

    std::cout << hi << " " << f.myString2 << std::endl;

    std::cin >> f.myString2;

    std::cout << hi << " " << f.myString2 << std::endl;

    return 0;
}

I tested this in Visual Studio 2013. Unfortunately in order to use the underlying storage inside the LambdaSetter I needed to provide a "GetRawData" public accessor which can lead to broken encapsulation, but you can either leave it out and provide your own storage container for T or just ensure that the only time you use "GetRawData" is when you are writing a custom getter/setter method.

$(document).on('change', '#id', aFunc);

function aFunc() {

Two more options based on CSS Text Module Level 3 (instead of white-space-collapsing:discard which had been dropped from the spec draft):

• word-spacing: -100%;

In theory, it should do exactly what is needed — shorten whitespaces between 'words' by the 100% of the space character width, i.e. to zero. But seems not to work anywhere, unfortunately, and this feature is marked 'at risk' (it can be dropped from the specification, too).

• word-spacing: -1ch;

It shortens the inter-word spaces by the width of the digit '0'. In a monospace font it should be exactly equal to the width of the space character (and any other character as well). This works in Firefox 10+, Chrome 27+, and almost works in Internet Explorer 9+.

Fiddle

in my case the solution was to set the proxy to "native" I had configured the proxy under linux with cntlm and also in Firefox (used as eclipse browser also.

You are assigning a numeric value to a text field. You have to convert the numeric value to a string with:

String.valueOf(variable)

Simply drag a ContextMenu or ContextMenuStrip component into your form and visually design it, then assign it to the ContextMenu or ContextMenuStrip property of your desired control.

I tried this for to clear Image and DrawableCache in ImageView

ImgView.setImageBitmap(null);
ImgView.destroyDrawingCache();

I hope this works for you !

There isn't any function in the standard library (to my knowledge) that will do it, but there are absolutely modules out there which have such functions. However, its easy enough that you can just write your own function:

def normalize(lst):
    s = sum(lst)
    return map(lambda x: float(x)/s, lst)

Sample output:

>>> normed = normalize(raw)
>>> normed
[0.25, 0.5, 0.25]

I strongly favour minimal file headers, by which I mean just:

• The hashbang (#! line) if this is an executable script
• Module docstring
• Imports, grouped in the standard way, eg:

  import os    # standard library
  import sys

  import requests  # 3rd party packages

  from mypackage import (  # local source
      mymodule,
      myothermodule,
  )

ie. three groups of imports, with a single blank line between them. Within each group, imports are sorted. The final group, imports from local source, can either be absolute imports as shown, or explicit relative imports.

Everything else is a waste of time, visual space, and is actively misleading.

If you have legal disclaimers or licencing info, it goes into a separate file. It does not need to infect every source code file. Your copyright should be part of this. People should be able to find it in your LICENSE file, not random source code.

Metadata such as authorship and dates is already maintained by your source control. There is no need to add a less-detailed, erroneous, and out-of-date version of the same info in the file itself.

I don't believe there is any other data that everyone needs to put into all their source files. You may have some particular requirement to do so, but such things apply, by definition, only to you. They have no place in “general headers recommended for everyone”.

I seem to have a blind spot as regards your html structure, but I think that this is what you're looking for. It should find the currently-selected option from the select input, assign its text to the newVal variable and then apply that variable to the value attribute of the #costLabel label:

jQuery

$(document).ready(
  function() {
    $('select[name=package]').change(
      function(){
        var newText = $('option:selected',this).text();
        $('#costLabel').text('Total price: ' + newText);
      }
      );
  }
  );

html:

  <form name="thisForm" id="thisForm" action="#" method="post">
  <fieldset>
    <select name="package" id="package">
        <option value="standard">Standard - &euro;55 Monthly</option>
        <option value="standardAnn">Standard - &euro;49 Monthly</option>            
        <option value="premium">Premium - &euro;99 Monthly</option>
        <option value="premiumAnn" selected="selected">Premium - &euro;89 Monthly</option>            
        <option value="platinum">Platinum - &euro;149 Monthly</option>
        <option value="platinumAnn">Platinum - &euro;134 Monthly</option>   
    </select>
  </fieldset>
    
    <fieldset>
      <label id="costLabel" name="costLabel">Total price: </label>
    </fieldset>
  </form>

Working demo of the above at: JS Bin

From the ECMAScript specification, Section 11.9.3 The Abstract Equality Comparison Algorithm:

The comparison x == y, where x and y are values, produces true or false. Such a comparison is performed as follows:

• If Type(y) is Boolean, return the result of the comparison x == ToNumber(y).

Thus, in, if (1 == true), true gets coerced to a Number, i.e. Number(true), which results in the value of 1, yielding the final if (1 == 1) which is true.

if (0 == false) is the exact same logic, since Number(false) == 0.

This doesn't happen when you use the strict equals operator === instead:

11.9.6 The Strict Equality Comparison Algorithm

The comparison x === y, where x and y are values, produces true or false. Such a comparison is performed as follows:

• If Type(x) is different from Type(y), return false.

That is for people who prefer to have the constant on the left side. In most cases having the constant on the left side will prevent NullPointerException to be thrown (or having another nullcheck). For example the String method equals does also a null check. Having the constant on the left, will keep you from writing the additional check. Which, in another way is also performed later. Having the null value on the left is just being consistent.

like:

 String b = null;
 "constant".equals(b);  // result to false
 b.equals("constant");  // NullPointerException
 b != null && b.equals("constant");  // result to false

The steps in order to make a full check are:

Prepare the captor :

ArgumentCaptor<SomeArgumentClass> someArgumentCaptor = ArgumentCaptor.forClass(SomeArgumentClass.class);

verify the call to dependent on component (collaborator of subject under test). times(1) is the default value, so ne need to add it.

verify(dependentOnComponent, times(1)).send(someArgumentCaptor.capture());

Get the argument passed to collaborator

SomeArgumentClass someArgument = messageCaptor.getValue();

someArgument can be used for assertions

Take a look at this image, I created one very simple example for demonstration of const and let variables. As you can see, when you try to change const variable, you will get the error (Attempting to override 'name' which is constant'), but take a look at let variable...

First we declare let age = 33, and later assign some other value age = 34;, which is ok, we dont have any errors when we try to change let variable

React Native Debugger. It's helps me to solve 90% of my problems

Just tried on my machine compiling this :

int a = ...;
int b = a * 10;

When disassembling it produces output :

MOV EAX,DWORD PTR SS:[ESP+1C] ; Move a into EAX
LEA EAX,DWORD PTR DS:[EAX+EAX*4] ; Multiply by 5 without shift !
SHL EAX, 1 ; Multiply by 2 using shift

This version is faster than your hand-optimized code with pure shifting and addition.

You really never know what the compiler is going to come up with, so it's better to simply write a normal multiplication and let him optimize the way he wants to, except in very precise cases where you know the compiler cannot optimize.

You can press I twice to interrupt the kernel.

This only works if you're in Command mode. If not already enabled, press Esc to enable it.

You should set a condition loop to check the TextBox1 value.

If TextBox1.value = "" then
   MsgBox "The file not exist" 
   Exit sub 'exit the macro
End If

Hope it help you.

Should it not be foreach instead of for!?

//call SQL helper class to get initial data  
DataTable dt = sql.ExecuteDataTable("sp_MyProc"); 

dt.Columns.Add("MyRow", **typeof**(System.Int32)); 

foreach(DataRow dr in dt.Rows) 
{ 
    //need to set value to MyRow column 
    dr["MyRow"] = 0;   // or set it to some other value 
} 

• I would suggest you to extract the table using tabula.
• Pass your pdf as an argument to the tabula api and it will return you the table in the form of dataframe.
• Each table in your pdf is returned as one dataframe.
• The table will be returned in a list of dataframea, for working with dataframe you need pandas.

This is my code for extracting pdf.

import pandas as pd
import tabula
file = "filename.pdf"
path = 'enter your directory path here'  + file
df = tabula.read_pdf(path, pages = '1', multiple_tables = True)
print(df)

Please refer to this repo of mine for more details.

An alternative is to use String.format:

double[] arr = { 23.59004,
    35.7,
    3.0,
    9
};

for ( double dub : arr ) {
  System.out.println( String.format( "%.2f", dub ) );
}

output:

23.59
35.70
3.00
9.00

You could also use System.out.format (same method signature), or create a java.util.Formatter which works in the same way.

Use this if the session variable emp_num will store a string:

 if (!string.IsNullOrEmpty(Session["emp_num"] as string))
 {
                //The code
 }

If it doesn't store a string, but some other type, you should just check for null before accessing the value, as in your second example.

SELECT Id, Link, Day, Month FROM Posted
WHERE Id IN(
   SELECT Min(Id) FROM Posted GROUP BY Link)

d={1:'a',2:'b'}
sum=0
for i in range(0,len(d),1):
   sum=sum+1
i=i+1
print i

OUTPUT=2

For others who are experiencing with the same problem, here is the description of the bug in php + patch https://bugs.php.net/bug.php?id=44522

This worked for me:

Super simple in-place assignment: df['new'] = 0

For in-place modification, perform direct assignment. This assignment is broadcasted by pandas for each row.

df = pd.DataFrame('x', index=range(4), columns=list('ABC'))
df

   A  B  C
0  x  x  x
1  x  x  x
2  x  x  x
3  x  x  x

df['new'] = 'y'
# Same as,
# df.loc[:, 'new'] = 'y'
df

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

Note for object columns

If you want to add an column of empty lists, here is my advice:

• Consider not doing this. object columns are bad news in terms of performance. Rethink how your data is structured.
• Consider storing your data in a sparse data structure. More information: sparse data structures

• If you must store a column of lists, ensure not to copy the same reference multiple times.

  # Wrong
  df['new'] = [[]] * len(df)
  # Right
  df['new'] = [[] for _ in range(len(df))]
  

Generating a copy: df.assign(new=0)

If you need a copy instead, use DataFrame.assign:

df.assign(new='y')

   A  B  C new
0  x  x  x   y
1  x  x  x   y
2  x  x  x   y
3  x  x  x   y

And, if you need to assign multiple such columns with the same value, this is as simple as,

c = ['new1', 'new2', ...]
df.assign(**dict.fromkeys(c, 'y'))

   A  B  C new1 new2
0  x  x  x    y    y
1  x  x  x    y    y
2  x  x  x    y    y
3  x  x  x    y    y

Multiple column assignment

Finally, if you need to assign multiple columns with different values, you can use assign with a dictionary.

c = {'new1': 'w', 'new2': 'y', 'new3': 'z'}
df.assign(**c)

   A  B  C new1 new2 new3
0  x  x  x    w    y    z
1  x  x  x    w    y    z
2  x  x  x    w    y    z
3  x  x  x    w    y    z

This problem commonly occurs when switching from py2 to py3. In py2 plaintext is both a string and a byte array type. In py3 plaintext is only a string, and the method outfile.write() actually takes a byte array when outfile is opened in binary mode, so an exception is raised. Change the input to plaintext.encode('utf-8') to fix the problem. Read on if this bothers you.

In py2, the declaration for file.write made it seem like you passed in a string: file.write(str). Actually you were passing in a byte array, you should have been reading the declaration like this: file.write(bytes). If you read it like this the problem is simple, file.write(bytes) needs a bytes type and in py3 to get bytes out of a str you convert it:

py3>> outfile.write(plaintext.encode('utf-8'))

Why did the py2 docs declare file.write took a string? Well in py2 the declaration distinction didn't matter because:

py2>> str==bytes         #str and bytes aliased a single hybrid class in py2
True

The str-bytes class of py2 has methods/constructors that make it behave like a string class in some ways and a byte array class in others. Convenient for file.write isn't it?:

py2>> plaintext='my string literal'
py2>> type(plaintext)
str                              #is it a string or is it a byte array? it's both!

py2>> outfile.write(plaintext)   #can use plaintext as a byte array

Why did py3 break this nice system? Well because in py2 basic string functions didn't work for the rest of the world. Measure the length of a word with a non-ASCII character?

py2>> len('¡no')        #length of string=3, length of UTF-8 byte array=4, since with variable len encoding the non-ASCII chars = 2-6 bytes
4                       #always gives bytes.len not str.len

All this time you thought you were asking for the len of a string in py2, you were getting the length of the byte array from the encoding. That ambiguity is the fundamental problem with double-duty classes. Which version of any method call do you implement?

The good news then is that py3 fixes this problem. It disentangles the str and bytes classes. The str class has string-like methods, the separate bytes class has byte array methods:

py3>> len('¡ok')       #string
3
py3>> len('¡ok'.encode('utf-8'))     #bytes
4

Hopefully knowing this helps de-mystify the issue, and makes the migration pain a little easier to bear.

If you don't want to install extensions, you can simply prepend the URL with view-source:, e.g. view-source:http://content.dimestore.com/prod/survey_data/4535/4535.json. This usually works in Firefox and Chrome (will still offer to download the file however if Content-Disposition: attachment header is present).

Adding to Dmitri Chebotarev Answer,

If you want to alter multiple columns at a time , you can do it like below

DB::statement('
     ALTER TABLE `events` 
            MODIFY `event_date` DATE NOT NULL,
            MODIFY `event_start_time` TIME NOT NULL,
            MODIFY `event_end_time` TIME NOT NULL;
');

From what I know when I look at this question here

It said there that "in PHP, there is a distinct difference in Header output. In the examples below I chose to use a different header but for sake of showing the difference between exit() and die() that doesn't matter", and tested (personally)

If you use rs.next() you will move the cursor, than you should to move first() why don't check using first() directly?

    public void fetchData(ResultSet res, JTable table) throws SQLException{     
    ResultSetMetaData metaData = res.getMetaData();
    int fieldsCount = metaData.getColumnCount();
    for (int i = 1; i <= fieldsCount; i++)
        ((DefaultTableModel) table.getModel()).addColumn(metaData.getColumnLabel(i));
    if (!res.first())
        JOptionPane.showMessageDialog(rootPane, "no data!");
    else
        do {
            Vector<Object> v = new Vector<Object>();
            for (int i = 1; i <= fieldsCount; i++)              
                v.addElement(res.getObject(i));         
            ((DefaultTableModel) table.getModel()).addRow(v);
        } while (res.next());
        res.close();
}

In Java you can only import class Names, or static methods/fields.

To import class use

import full.package.name.of.SomeClass;

We can also import static methods/fields in Java and this is how to import

import static full.package.nameOfClass.staticMethod;
import static full.package.nameOfClass.staticField;

There are certain scenarios in which you can follow the steps suggested in the other answers, verify that Execution Policy is set correctly, and still have your scripts fail. If this happens to you, you are probably on a 64-bit machine with both 32-bit and 64-bit versions of PowerShell, and the failure is happening on the version that doesn't have Execution Policy set. The setting does not apply to both versions, so you have to explicitly set it twice.

Look in your Windows directory for System32 and SysWOW64.

Repeat these steps for each directory:

1. Navigate to WindowsPowerShell\v1.0 and launch powershell.exe

2. Check the current setting for ExecutionPolicy:

   Get-ExecutionPolicy -List

3. Set the ExecutionPolicy for the level and scope you want, for example:

   Set-ExecutionPolicy -Scope LocalMachine Unrestricted

Note that you may need to run PowerShell as administrator depending on the scope you are trying to set the policy for.

You can read a lot more here: Running Windows PowerShell Scripts

If you have recently installed or updated the Microsoft.CodeDom.Providers.DotNetCompilerPlatform package, double-check that the versions of that package referenced in your project point to the correct, and same, version of that package:

• In ProjectName.csproj, ensure that an <Import> tag for Microsoft.CodeDom.Providers.DotNetCompilerPlatform is present and points to the correct version.

• In ProjectName.csproj, ensure that a <Reference> tag for Microsoft.CodeDom.Providers.DotNetCompilerPlatform is present, and points to the correct version, both in the Include attribute and the child <HintPath>.

• In that project's web.config, ensure that the <system.codedom> tag is present, and that its child <compiler> tags have the same version in their type attribute.

For some reason, in my case an upgrade of this package from 1.0.5 to 1.0.8 caused the <Reference> tag in the.csproj to have its Include pointing to the old version 1.0.5.0 (which I had deleted after upgrading the package), but everything else was pointing to the new and correct version 1.0.8.0.

Use below code.

NSString* myString;
myString = [[NSString alloc] initWithData:nsdata encoding:NSASCIIStringEncoding];

Note that if you want to scroll an element instead of the full window, elements don't have the scrollTo and scrollBy methods. You should:

var el = document.getElementById("myel"); // Or whatever method to get the element

// To set the scroll
el.scrollTop = 0;
el.scrollLeft = 0;

// To increment the scroll
el.scrollTop += 100;
el.scrollLeft += 100;

You can also mimic the window.scrollTo and window.scrollBy functions to all the existant HTML elements in the webpage on browsers that don't support it natively:

Object.defineProperty(HTMLElement.prototype, "scrollTo", {
    value: function(x, y) {
        el.scrollTop = y;
        el.scrollLeft = x;
    },
    enumerable: false
});

Object.defineProperty(HTMLElement.prototype, "scrollBy", {
    value: function(x, y) {
        el.scrollTop += y;
        el.scrollLeft += x;
    },
    enumerable: false
});

so you can do:

var el = document.getElementById("myel"); // Or whatever method to get the element, again

// To set the scroll
el.scrollTo(0, 0);

// To increment the scroll
el.scrollBy(100, 100);

NOTE: Object.defineProperty is encouraged, as directly adding properties to the prototype is a breaking bad habit (When you see it :-).

A simple JavaScript function will do the job.

function ClearFields() {

     document.getElementById("textfield1").value = "";
     document.getElementById("textfield2").value = "";
}

And just have your button call it:

<button type="button" onclick="ClearFields();">Clear</button>

In system/core/Common.php there is an exception handler, with a block of code that looks like this:

 // We don't bother with "strict" notices since they tend to fill up
 // the log file with excess information that isn't normally very helpful.
if ($severity == E_STRICT)
{
    return;
}

By removing the if and the return and the incorrect comment, I was able to get an error message, instead of just a blank page. This project isn't using the most recent version of CodeIgniter, hopefully they've fixed this bug by now.

Use python's csv module for reading and writing comma or tab-delimited files. The csv module is preferred because it gives you good control over quoting.

For example, here is the worked example for you:

import csv
data = ["value %d" % i for i in range(1,4)]

out = csv.writer(open("myfile.csv","w"), delimiter=',',quoting=csv.QUOTE_ALL)
out.writerow(data)

Produces:

"value 1","value 2","value 3"

To clone your class object you can use the Object.MemberwiseClone method,

just add this function to your class :

public class yourClass
{
    // ...
    // ...

    public yourClass DeepCopy()
    {
        yourClass othercopy = (yourClass)this.MemberwiseClone();
        return othercopy;
    }
}

then to perform a deep independant copy, just call the DeepCopy method :

yourClass newLine = oldLine.DeepCopy();

I used the copy command with the /z switch for copying over network drives. Also works for copying between local drives. Tested on XP Home edition.

This is an older post, however as the info is still relevant today an additional option may help others.

• Define a constant for the file path per Stefan's answer. The definition can be placed at the top of the PHP page itself, or within an included/required external file such as config.php. (http://php.net/manual/en/function.include.php)

• Echo the constant in PHP tags, then add the filename directly after. That's it!
  Works for other linked files such as JavaScript as well.

<?php
define('CSS_PATH', 'template/css/'); //define CSS path 
define('JS_PATH', 'template/js/'); //define JavaScript path 
?>
<!-- Doctype should be declared, even in PHP file -->
<!DOCTYPE html> 
<html>
<head>
<link rel="stylesheet" type="text/css" href="<?php echo CSS_PATH; ?>main.css">
<script type="text/javascript" src="<?php echo JS_PATH; ?>main.js"></script>
</head>
<body>
</body>
</html>

I agree that this var formattedString = string.replace(/'/g, "\\'"); works very well, but since I used this part of code in PHP with the framework Prado (you can register the js script in a PHP class) I needed this sample working inside double quotes.

The solution that worked for me is that you need to put three \ and escape the double quotes. "var string = \"l'avancement\"; var formattedString = string.replace(/'/g, \"\\\'\");"

I answer that question since I had trouble finding that three \ was the work around.

You can use the Web API FontFace constructor (also Typescript) without need of CSS:

export async function loadFont(fontFamily: string, url: string): Promise<void> {
    const font = new FontFace(fontFamily, `local(${fontFamily}), url(${url})`);
    // wait for font to be loaded
    await font.load();
    // add font to document
    document.fonts.add(font);
    // enable font with CSS class
    document.body.classList.add("fonts-loaded");
}

import ComicSans from "./assets/fonts/ComicSans.ttf";

loadFont("Comic Sans ", ComicSans).catch((e) => {
    console.log(e);
});

Declare a file font.ts with your modules (TS only):

declare module "*.ttf";
declare module "*.woff";
declare module "*.woff2";

If TS cannot find FontFace type as its still officially WIP, add this declaration to your project. It will work in your browser, except for IE.

On Oracle 9.2+ (not 8i+ as originally stated), SQL Server 2005+, PostgreSQL 8.4+, DB2, Firebird 3.0+, Teradata, Sybase, Vertica:

WITH summary AS (
    SELECT p.id, 
           p.customer, 
           p.total, 
           ROW_NUMBER() OVER(PARTITION BY p.customer 
                                 ORDER BY p.total DESC) AS rk
      FROM PURCHASES p)
SELECT s.*
  FROM summary s
 WHERE s.rk = 1

Supported by any database:

But you need to add logic to break ties:

  SELECT MIN(x.id),  -- change to MAX if you want the highest
         x.customer, 
         x.total
    FROM PURCHASES x
    JOIN (SELECT p.customer,
                 MAX(total) AS max_total
            FROM PURCHASES p
        GROUP BY p.customer) y ON y.customer = x.customer
                              AND y.max_total = x.total
GROUP BY x.customer, x.total

The idle shortcut is an "Advertised Shortcut" which breaks certain features like the "find target" button. Google for more info.

You can view the link with a hex editor or download LNK Parser to see where it points to.

In my case it runs:
..\..\..\..\..\Python27\pythonw.exe "C:\Python27\Lib\idlelib\idle.pyw"

foreach (DictionaryEntry entry in Hashtable)
{
    datagridviewTZ.Rows.Add(entry.Key.ToString(), entry.Value.ToString());
}

If you want to submit files using ajax use "jquery.form.js" This submits all form elements easily.

Samples http://jquery.malsup.com/form/#ajaxSubmit

rough view :

<form id='AddPhotoForm' method='post' action='../photo/admin_save_photo.php' enctype='multipart/form-data'>

<script type="text/javascript">
function showResponseAfterAddPhoto(responseText, statusText)
{ 
    information= responseText;
    callAjaxtolist();
    $("#AddPhotoForm").resetForm();
    $("#photo_msg").html('<div class="album_msg">Photo uploaded Successfully...</div>');        
};

$(document).ready(function(){
    $('.add_new_photo_div').live('click',function(){
            var options = {success:showResponseAfterAddPhoto};  
            $("#AddPhotoForm").ajaxSubmit(options);
        });
});
</script>

You can recursively os.path.split the string

import os
def parts(path):
    p,f = os.path.split(path)
    return parts(p) + [f] if f else [p]

Testing this against some path strings, and reassembling the path with os.path.join

>>> for path in [
...         r'd:\stuff\morestuff\furtherdown\THEFILE.txt',
...         '/path/to/file.txt',
...         'relative/path/to/file.txt',
...         r'C:\path\to\file.txt',
...         r'\\host\share\path\to\file.txt',
...     ]:
...     print parts(path), os.path.join(*parts(path))
... 
['d:\\', 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt'] d:\stuff\morestuff\furtherdown\THEFILE.txt
['/', 'path', 'to', 'file.txt'] /path\to\file.txt
['', 'relative', 'path', 'to', 'file.txt'] relative\path\to\file.txt
['C:\\', 'path', 'to', 'file.txt'] C:\path\to\file.txt
['\\\\', 'host', 'share', 'path', 'to', 'file.txt'] \\host\share\path\to\file.txt

The first element of the list may need to be treated differently depending on how you want to deal with drive letters, UNC paths and absolute and relative paths. Changing the last [p] to [os.path.splitdrive(p)] forces the issue by splitting the drive letter and directory root out into a tuple.

import os
def parts(path):
    p,f = os.path.split(path)
    return parts(p) + [f] if f else [os.path.splitdrive(p)]

[('d:', '\\'), 'stuff', 'morestuff', 'furtherdown', 'THEFILE.txt']
[('', '/'), 'path', 'to', 'file.txt']
[('', ''), 'relative', 'path', 'to', 'file.txt']
[('C:', '\\'), 'path', 'to', 'file.txt']
[('', '\\\\'), 'host', 'share', 'path', 'to', 'file.txt']

Edit: I have realised that this answer is very similar to that given above by user1556435. I'm leaving my answer up as the handling of the drive component of the path is different.

You get this if itemdescription is shorter than 38 characters

You can look which exceptions are thrown and when in the JAVA API in you case for String#substring(int,int): https://docs.oracle.com/javase/9/docs/api/java/lang/String.html#substring-int-int-

substring
public String substring(int beginIndex, int endIndex)
   . . .

Throws:
 IndexOutOfBoundsException
 if the beginIndex is negative,
 or endIndex is larger than the length of this String object, 
 or beginIndex is larger than endIndex.



(same applies to previous java versions as well)

The initialize method is called after all @FXML annotated members have been injected. Suppose you have a table view you want to populate with data:

class MyController { 
    @FXML
    TableView<MyModel> tableView; 

    public MyController() {
        tableView.getItems().addAll(getDataFromSource()); // results in NullPointerException, as tableView is null at this point. 
    }

    @FXML
    public void initialize() {
        tableView.getItems().addAll(getDataFromSource()); // Perfectly Ok here, as FXMLLoader already populated all @FXML annotated members. 
    }
}

var countries = ['United States', 'Canada', 'Argentina', 'Armenia'];
var cList = $('ul.mylist')
$.each(countries, function(i) {
    var li = $('<li/>')
        .addClass('ui-menu-item')
        .attr('role', 'menuitem')
        .appendTo(cList);
    var a = $('<a/>')
        .addClass('ui-all')
        .text( this )
        .appendTo(li);
});

I tried the two top-voted solutions but found some issues even though both work to some extent.

• List item: The new package-drag-drop method leaves some unchanged and creates some undesired effects
• List item: The rename package only changes the last part of package name

After some experiments I found the following method works well for me.

If you just need to change the last part of package name, use the method outlined by GreyBeardedGeek, namely

Right-click on the package in the Project pane. Choose Refactor -> Rename from the context menu

If you need to change the whole package name, do the following.

Right-click on the package in the Project pane. Choose Refactor -> Move from the context menu

This will create a new package folder (when necessary) but will keep the last part of your package name as before. If you need to change the last part, do the rename accordingly.

Note also that you may need to modify package names in e.g. build.gradle, manifest, and/or any xml resource files, or even in your code if hardcoded. After all that, do Sync/Clean/Rebuild project as necessary.

MVC 4 example...

Note that you do not always have to pass parameter named ID

var message = model.UserName + " - thanks for taking yourtime to register on our glorious site. ";
return RedirectToAction("ThankYou", "Account", new { whatever = message });

And,

public ActionResult ThankYou(string whatever) {
        ViewBag.message = whatever;
        return View();
} 

Of course you can assign string to model fields instead of using ViewBag if that is your preference.

I had the same issue, this solved it for me:

ALTER TABLE `my_table` ROW_FORMAT=DYNAMIC;

From MYSQL Documentation:

The DYNAMIC row format maintains the efficiency of storing the entire row in the index node if it fits (as do the COMPACT and REDUNDANT formats), but this new format avoids the problem of filling B-tree nodes with a large number of data bytes of long columns. The DYNAMIC format is based on the idea that if a portion of a long data value is stored off-page, it is usually most efficient to store all of the value off-page. With DYNAMIC format, shorter columns are likely to remain in the B-tree node, minimizing the number of overflow pages needed for any given row.

I had the same problem. I'm using DB2. What I have done is a bit not too professional solution, but it works in every DBMS:

1. Add a column with the same definition without the unique contraint.
2. Copy the values from the original column to the new
3. Drop the original column (so DBMS will remove the constraint as well no matter what its name was)
4. And finally rename the new one to the original
5. And a reorg at the end (only in DB2)

ALTER TABLE USERS ADD COLUMN LOGIN_OLD VARCHAR(50) NOT NULL DEFAULT '';
UPDATE USERS SET LOGIN_OLD=LOGIN;
ALTER TABLE USERS DROP COLUMN LOGIN;
ALTER TABLE USERS RENAME COLUMN LOGIN_OLD TO LOGIN;

CALL SYSPROC.ADMIN_CMD('REORG TABLE USERS');

The syntax of the ALTER commands may be different in other DBMS

I just removed 'href' attribute from that anchor tag which I want to disable

$('#idOfAnchorTag').removeAttr('href');

$('#idOfAnchorTag').attr('class', $('#idOfAnchorTag').attr('class')+ ' disabled');

I am using IntelliJ 2020.3.1 and the File > Other Settings... menu option has disappeared. I went to Settings in the usual way and searched for "jdk". Under Build, Execution, Deployment > Build Tools > Maven > Importing I found the the setting that will solve my specific issue:

JDK for importer.

I have tried many of these solutions. I ended up adding this to the top of my main file (e.g. index.js):

process.env.NODE_PATH = __dirname;
require('module').Module._initPaths();

This adds the project root to the NODE_PATH when the script is loaded. The allows me to require any file in my project by referencing its relative path from the project root such as var User = require('models/user'). This solution should work as long as you are running a main script in the project root before running anything else in your project.

As a variation of Bridge's answer (I don't yet have enough rep to comment, and didn't feel right about editing that answer), here is a version that works better for me.

SELECT column_name AS [Name],
   IS_NULLABLE AS [Null?],
   DATA_TYPE + CASE
                 WHEN CHARACTER_MAXIMUM_LENGTH IS NULL THEN ''
                 WHEN CHARACTER_MAXIMUM_LENGTH > 99999 THEN ''
                 ELSE '(' + Cast(CHARACTER_MAXIMUM_LENGTH AS VARCHAR(5)) + ')' 
               END AS [Type]
FROM   INFORMATION_SCHEMA.Columns
WHERE  table_name = 'table_name'

Notable changes:

• Works for types without length. For an int column, I was seeing NULL for the type because the length was null and it wiped out the whole Type column. So don't print any length component (or parens).
• Change the check for CAST length of -1 to check actual length. I was getting a syntax error because the case resulted in '*' rather than -1. Seems to make more sense to perform an arithmetic check rather than an overflow from the CAST.
• Don't print length when very long (arbitrarily > 5 digits).

See code example below:

SimpleDateFormat df = new SimpleDateFormat("hh:mm");
String formattedDate = df.format(new Date());
out.println(formattedDate);

I ran across this article in the results returned by a search related to the IF command in a batch file, and I couldn't resist the opportunity to correct the misconception that IF blocks are limited to single commands. Following is a portion of a production Windows NT command script that runs daily on the machine on which I am composing this reply.

    if "%COPYTOOL%" equ "R" (
    WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using RoboCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
    %TOOLPATH% %SRCEPATH% %DESTPATH% /copyall %RCLOGSTR% /m /np /r:0 /tee
    C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Robocopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
) else (
    WWLOGGER.exe "%APPDATA%\WizardWrx\%~n0.LOG" "Using XCopy to make a backup of %USERPROFILE%\My Documents\Outlook Files\*"
    call %TOOLPATH%  "%USERPROFILE%\My Documents\Outlook Files\*" "%USERPROFILE%\My Documents\Outlook Files\_backups" /f /m /v /y
    C:\BIN\ExitCodeMapper.exe C:\BIN\ExitCodeMapper.INI[Xcopy] %TEMP%\%~n0.TMP %ERRORLEVEL%
)

Perhaps blocks of two or more lines applies exclusively to Windows NT command scripts (.CMD files), because a search of the production scripts directory of an application that is restricted to old school batch (.BAT) files, revealed only one-command blocks. Since the application has gone into extended maintenance (meaning that I am not actively involved in supporting it), I can't say whether that is because I didn't need more than one line, or that I couldn't make them work.

Regardless, if the latter is true, there is a simple workaround; move the multiple lines into either a separate batch file or a batch file subroutine. I know that the latter works in both kinds of scripts.

Follow instructions for IntelliJ JD plugin. Or see an excerpt from the instructions below.

java -jar fernflower.jar [<source>]+ <destination>

+ means 1 or more times
<source>: file or directory with files to be decompiled. Directories are recursively scanned. Allowed file extensions are class, zip and jar.
<destination>: destination directory

Example:

java -jar fernflower.jar -hdc=0 -dgs=1 -rsy=1 -lit=1 c:\Temp\binary\ -e=c:\Java\rt.jar c:\Temp\source\

Be aware that if you pass it a ".jar" file for the source, it will create another ".jar" file in the destination, however, within the new ".jar" file, the files will be .java instead of .class files (it doesn't explode the jar).

UPDATE

People ask me: How do I get the fernflower.jar?

If you have any IntelliJ product installed, chances are that you already have the Fernflower decompiler on your computer. IntelliJ IDEA comes with Java Bytecode Decompiler plugin (bundled) which is a modern extension of Fernflower.

1. Locate the file in ${IntelliJ_INSTALL_DIR}\plugins\java-decompiler\lib\java-decompiler.jar (example: C:\Program Files\JetBrains\IntelliJ IDEA 2018\plugins\java-decompiler\lib).
2. Copy it somewhere and rename to fernflower.jar (optional).

3. This JAR is not executable, so we can't run it using java -jar. However something like this works:

   java -cp fernflower.jar org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler [<source>]+ <destination>
   

   org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler is the class that contains the main method to run the decompiler.

   Example:

   mkdir output_src
   java -cp fernflower.jar org.jetbrains.java.decompiler.main.decompiler.ConsoleDecompiler -hdc=0 -dgs=1 -rsy=1 -lit=1 ./input.jar ./output_src
   

If you don't have IntelliJ products installed, either download it now (available on jetbrains.com) or make your own decompiler executable from sources (available on Github).

If you're doing the check inside the View, put the value in the ViewBag.

In your controller:

ViewBag["parameterName"] = Request["parameterName"];

It's worth noting that the Request and Response properties are exposed by the Controller class. They have the same semantics as HttpRequest and HttpResponse.

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

If you use Kotlin, you can do the following:

1. On first, you should be create Interface and implemented him in your Fragment

interface RefreshData {
    fun refresh()
}

class YourFragment : Fragment(), RefreshData {
    ...
    override fun refresh() {
        //do what you want
    }
}

2. Next step is add OnPageChangeListener to your ViewPager

viewPager.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
    override fun onPageScrollStateChanged(state: Int) { }

    override fun onPageSelected(position: Int) {
        viewPagerAdapter.notifyDataSetChanged()
        viewPager.currentItem = position
    }

    override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) { }
})

3. override getItemPosition in your Adapter

override fun getItemPosition(obj: Any): Int {
    if (obj is RefreshData) {
        obj.refresh()
    }
    return super.getItemPosition(obj)
}

Your method will return a local stack variable that will fail badly. To return an array, create one outside the function, pass it by address into the function, then modify it, or create an array on the heap and return that variable. Both will work, but the first doesn't require any dynamic memory allocation to get it working correctly.

void returnArray(int size, char *retArray)
{
  // work directly with retArray or memcpy into it from elsewhere like
  // memcpy(retArray, localArray, size); 
}

#define ARRAY_SIZE 20

int main(void)
{
  char foo[ARRAY_SIZE];
  returnArray(ARRAY_SIZE, foo);
}

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

The exact formula is:

=ArrayFormula(text(A1:A,"00000"))

ArrayFormula works on multiple rows (in the above example, every row), and results are placed in the cell with the formula and the cells below it in the same column. It looks as if the same formula was copied into all those rows.

If any of the cells in that column are not empty, they won't get overwritten. Instead, you will get an error message.

To save yourself typing, you can use the trick from the answer above by pnuts:

Type: =text(A1:A,"00000") and then hit the following key combination:

• On windows: Ctrl+Shift+Enter

• On a MAC: Command+Shift+Enter

This will convert the formula to ArrayFormula.

After hitting the key combination, you need to hit Enter, to actually apply the converted formula.

If your sheet contains header row(s), and you want to apply formula from (for example) row 5 on, you would use =text(A5:A,"00000") instead.

This answer includes information from pnuts's answer and LOAS's comment.

According to the documentation: https://jinja.palletsprojects.com/en/2.10.x/templates/#line-statements you may use multi-line statements as long as the code has parens/brackets around it. Example:

{% if ( (foo == 'foo' or bar == 'bar') and 
        (fooo == 'fooo' or baar == 'baar') ) %}
    <li>some text</li>
{% endif %}

Edit: Using line_statement_prefix = '#'* the code would look like this:

# if ( (foo == 'foo' or bar == 'bar') and 
       (fooo == 'fooo' or baar == 'baar') )
    <li>some text</li>
# endif

*Here's an example of how you'd specify the line_statement_prefix in the Environment:

from jinja2 import Environment, PackageLoader, select_autoescape
env = Environment(
    loader=PackageLoader('yourapplication', 'templates'),
    autoescape=select_autoescape(['html', 'xml']),
    line_statement_prefix='#'
)

Or using Flask:

from flask import Flask
app = Flask(__name__, instance_relative_config=True, static_folder='static')
app.jinja_env.filters['zip'] = zip
app.jinja_env.line_statement_prefix = '#'

If, for whatever reason, the delete key is not working (like it wasn't working for me), you can splice it out and then filter the undefined values:

// To cut out one element via arr.splice(indexToRemove, numberToRemove);
array.splice(key, 1)
array.filter(function(n){return n});

Don’t try and chain them since splice returns removed elements;

If you don't want the 2-way binding via [(ngModel)], do this:

<select (change)="selectedAccountName = $event.target.value">
  <option *ngFor="let acct of accountsList" [ngValue]="acct">{{ acct.name }}</option>
</select>

Just tested on my project on Angular 4 and it works! The accountsList is an array of Account objects in which name is a property of Account.

Interesting observation:
[ngValue]="acct" exerts the same result as [ngValue]="acct.name".
Don't know how Angular 4 accomplish it!

While it supports many other repository formats now, the Maven repository format is still the most common and well supported format for build and provisioning tools running on the JVM and beyond. This chapter shows example configurations for using the repository manager with Apache Maven and a number of other tools. The setups take advantage of merging many repositories and exposing them via a repository group. Setting this up is documented in the chapter in addition to the configuration used by specific tools.

Details

For exporting the instances of the classes you can use this syntax:

// export index.js
const Foo = require('./my/module/foo');
const Bar = require('./my/module/bar');

module.exports = {
    Foo : new Foo(),
    Bar : new Bar()
};

// import and run method
const {Foo,Bar} = require('module_name');
Foo.test();

I prefer a simple adaptation of csgillespie's method, foregoing the need of a function definition:

d[apply(d!=0, 1, all),]

where d is your data frame.

Simplest solution is to just make the left div width equal 100% - the width of the right div plus any margin between them.

      <li><a href="#4">NavLink4</a></li>
      <li><a href="#5">NavLink5</a></li>
    </ul>
  </nav>
</div>

"abcd4yyyy" | grep 4 -c gives the count as 1

While the accepted and most upvoted answer is great, I additionally find it useful trying to explain the difference only by words:

merge

• “okay, we got two differently developed states of our repository. Let's merge them together. Two parents, one resulting child.”

rebase

• “Give the changes of the main branch (whatever its name) to my feature branch. Do so by pretending my feature work started later, in fact on the current state of the main branch.”
• “Rewrite the history of my changes to reflect that.” (need to force-push them, because normally versioning is all about not tampering with given history)
• “Likely —if the changes I raked in have little to do with my work— history actually won't change much, if I look at my commits diff by diff (you may also think of ‘patches’).“

summary: When possible, rebase is almost always better. Making re-integration into the main branch easier.

Because? ? your feature work can be presented as one big ‘patch file’ (aka diff) in respect to the main branch, not having to ‘explain’ multiple parents: At least two, coming from one merge, but likely many more, if there were several merges. Unlike merges, multiple rebases do not add up. (another big plus)

It appears to be a known issue.

http://bugs.mysql.com/bug.php?id=16757

Many IN queries can be re-written as (left outer) joins and an IS (NOT) NULL of some sort. for example

SELECT * FROM FOO WHERE ID IN (SELECT ID FROM FOO2)

can be re-written as

SELECT FOO.* FROM FOO JOIN FOO2 ON FOO.ID=FOO2.ID

or

SELECT * FROM FOO WHERE ID NOT IN (SELECT ID FROM FOO2)

can be

SELECT FOO.* FROM FOO 
LEFT OUTER JOIN FOO2 
ON FOO.ID=FOO2.ID WHERE FOO.ID IS NULL

All these solutions either break on tiny mouse movements, or are overcomplicated.

Here is a simple adaptable solution using two event listeners. Delta is the distance in pixels that you must move horizontally or vertically between the up and down events for the code to classify it as a drag rather than a click. This is because sometimes you will move the mouse or your finger a few pixels before lifting it.

const delta = 6;
let startX;
let startY;

element.addEventListener('mousedown', function (event) {
  startX = event.pageX;
  startY = event.pageY;
});

element.addEventListener('mouseup', function (event) {
  const diffX = Math.abs(event.pageX - startX);
  const diffY = Math.abs(event.pageY - startY);

  if (diffX < delta && diffY < delta) {
    // Click!
  }
});

If you want to transform a number into another number (not number to string of characters), and you can do with a small range (0 to 1023 for implementations with 32-bit integers), you don't need to add char* to the solution

unsigned int_to_int(unsigned k) {
    if (k == 0) return 0;
    if (k == 1) return 1;                       /* optional */
    return (k % 2) + 10 * int_to_int(k / 2);
}

HalosGhost suggested to compact the code into a single line

unsigned int int_to_int(unsigned int k) {
    return (k == 0 || k == 1 ? k : ((k % 2) + 10 * int_to_int(k / 2)));
}

I got this answer from the book Programming iOS 7, section Bar Position and Bar Metrics

If a navigation bar or toolbar — or a search bar (discussed earlier in this chapter) — is to occupy the top of the screen, the iOS 7 convention is that its height should be increased to underlap the transparent status bar. To make this possible, iOS 7 introduces the notion of a bar position.

UIBarPositionTopAttached

Specifies that the bar is at the top of the screen, as well as its containing view. Bars with this position draw their background extended upwards, allowing their background content to show through the status bar. Available in iOS 7.0 and later.

Whose special characters you want to remove from a string, prepare a list of them and then user javascript replace function to remove all special characters.

var str = 'abc'de#;:sfjkewr47239847duifyh';
alert(str.replace("'","").replace("#","").replace(";","").replace(":",""));

or you can run loop for a whole string and compare single single character with the ASCII code and regenerate a new string.

After setting the right permissions by adding the following code:

File myFile = ...;
myFile.setReadable(true, false); // readable, not only for the owner

adb pull works as desired.

see File.setReadable()

I found this somewhere else. I like this answer!

My experience in Visual Studio 2010 is that there are two changes needed so as to not need DLL's. From the project property page (right click on the project name in the Solution Explorer window):

1. Under Configuration Properties --> General, change the "Use of MFC" field to "Use MFC in a Static Library".

2. Under Configuration Properties --> C/C++ --> Code Generation, change the "Runtime Library" field to "Multi-Threaded (/MT)"

Not sure why both were needed. I used this to remove a dependency on glut32.dll.

Added later: When making these changes to the configurations, you should make them to "All Configurations" --- you can select this at the top of the Properties window. If you make the change to just the Debug configuration, it won't apply to the Release configuration, and vice-versa.

Try this:

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Path\To\Xml\File.xml");

Or alternatively if you have the XML in a string use the LoadXml method.

Once you have it loaded, you can use SelectNodes and SelectSingleNode to query specific values, for example:

XmlNode node = doc.SelectSingleNode("//Company/Email/text()");
// node.Value contains "[email protected]"

Finally, note that your XML is invalid as it doesn't contain a single root node. It must be something like this:

<Data>
    <Employee>
        <Name>Test</Name>
        <ID>123</ID>
    </Employee>
    <Company>
        <Name>ABC</Name>
        <Email>[email protected]</Email>
    </Company>
</Data>

Short and sweet

I'm not sure why none of the previous answers worked for me, but I came up with this solution during a eureka moment. It not only works, but it is also most elegant:

Add to body tag:

onmouseup="down=0;" onmousedown="down=1;"

Then test and execute myfunction() if down equals 1:

onmousemove="if (down==1) myfunction();"

Use CONCAT_WS().

SELECT CONCAT_WS(' ',firstname,lastname) as firstlast FROM users 
WHERE firstlast = "Bob Michael Jones";

The first argument is the separator for the rest of the arguments.

The apiKey in this configuration snippet just identifies your Firebase project on the Google servers. It is not a security risk for someone to know it. In fact, it is necessary for them to know it, in order for them to interact with your Firebase project. This same configuration data is also included in every iOS and Android app that uses Firebase as its backend.

In that sense it is very similar to the database URL that identifies the back-end database associated with your project in the same snippet: https://<app-id>.firebaseio.com. See this question on why this is not a security risk: How to restrict Firebase data modification?, including the use of Firebase's server side security rules to ensure only authorized users can access the backend services.

If you want to learn how to secure all data access to your Firebase backend services is authorized, read up on the documentation on Firebase security rules. These rules control access to file storage and database access, and are enforced on the Firebase servers. So no matter if it's your code, or somebody else's code that uses you configuration data, it can only do what the security rules allow it to do.

For another explanation of what Firebase uses these values for, and for which of them you can set quotas, see the Firebase documentation on using and managing API keys.

If you'd like to reduce the risk of committing this configuration data to version control, consider using the SDK auto-configuration of Firebase Hosting. While the keys will still end up in the browser in the same format, they won't be hard-coded into your code anymore with that.

Use following pattern:

/([^/]+)$

var mousewheelevt = (/Firefox/i.test(navigator.userAgent)) ? "DOMMouseScroll" : "mousewheel" //FF doesn't recognize mousewheel as of FF3.x
$(document).bind(mousewheelevt, 
function(e)
    {
        var evt = window.event || e //equalize event object     
        evt = evt.originalEvent ? evt.originalEvent : evt; //convert to originalEvent if possible               
        var delta = evt.detail ? evt.detail*(-40) : evt.wheelDelta //check for detail first, because it is used by Opera and FF
        if(delta > 0) 
            {
            scrollup();
            }
        else
            {
            scrolldown();
            }   
    }
);

I solved similar problem just by backing out of the project directory, then cd back into the project directory and bundle install.

This is my working version. Note that the resolvers code is not shown but are a spin on my implementation which allows columns to be resolved even though they are named slightly differently in each worksheet.

public static IEnumerable<T> ToArray<T>(this ExcelWorksheet worksheet, List<PropertyNameResolver> resolvers) where T : new()
{

  // List of all the column names
  var header = worksheet.Cells.GroupBy(cell => cell.Start.Row).First();

  // Get the properties from the type your are populating
  var properties = typeof(T).GetProperties().ToList();


  var start = worksheet.Dimension.Start;
  var end = worksheet.Dimension.End;

  // Resulting list
  var list = new List<T>();

  // Iterate the rows starting at row 2 (ie start.Row + 1)
  for (int row = start.Row + 1; row <= end.Row; row++)
  {
    var instance = new T();
    for (int col = start.Column; col <= end.Column; col++)
    {
      object value = worksheet.Cells[row, col].Text;

      // Get the column name zero based (ie col -1)
      var column = (string)header.Skip(col - 1).First().Value;

      // Gets the corresponding property to set
      var property = properties.Property(resolvers, column);

      try
      {
        var propertyName = property.PropertyType.IsGenericType
          ? property.PropertyType.GetGenericArguments().First().FullName
          : property.PropertyType.FullName;


        // Implement setter code as needed. 
        switch (propertyName)
        {
          case "System.String":
            property.SetValue(instance, Convert.ToString(value));
            break;
          case "System.Int32":
            property.SetValue(instance, Convert.ToInt32(value));
            break;
          case "System.DateTime":
            if (DateTime.TryParse((string) value, out var date))
            {
              property.SetValue(instance, date);
            }
            property.SetValue(instance, FromExcelSerialDate(Convert.ToInt32(value)));
            break;
          case "System.Boolean":
            property.SetValue(instance, (int)value == 1);
            break;
        }
      }
      catch (Exception e)
      {
        // instance property is empty because there was a problem.
      }

    } 
    list.Add(instance);
  }
  return list;
}

// Utility function taken from the above post's inline function.
public static DateTime FromExcelSerialDate(int excelDate)
{
  if (excelDate < 1)
    throw new ArgumentException("Excel dates cannot be smaller than 0.");

  var dateOfReference = new DateTime(1900, 1, 1);

  if (excelDate > 60d)
    excelDate = excelDate - 2;
  else
    excelDate = excelDate - 1;
  return dateOfReference.AddDays(excelDate);
}

You have a selector ul on line 252 which is setting list-style: square outside none (a square bullet). You'll have to change it to list-style: none or just remove the line.

If you only want to remove the bullets from that specific instance, you can use the specific selector for that list and its items as follows:

ul#groups-list.items-list { list-style: none }

First, add a textView in the XML file

<TextView  
    android:id="@+id/rate_id"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/what_U_want_to_display_in_first_time"
    />

then add a button in xml file with id btn_change_textView and write this two line of code in onCreate() method of activity

Button btn= (Button) findViewById(R.id. btn_change_textView);
TextView textView=(TextView)findViewById(R.id.rate_id);

then use clickListener() on button object like this

btn.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
      
        textView.setText("write here what u want to display after button click in string");
    }
});

ng version or ng --version or ng v OR ng -v

You can use this 4 commands to check the which version of angular-cli installed in your machine.

For me this problem still exists with SSMS version 2016 (13.0.16100.1).

A decent workaround is to not use the 'Right click' -> 'Add table...' dialog, but simply drag the table you want to add from the Object Explorer, onto the Diagram surface. While dragging the mouse icon changes into an 'add' symbol and the table is added when you release the mouse.

Beats having to close SSMS every time.

I prefer RENAME rather than DELETE

All my branches are named in the form of

• Fix/fix-<somedescription> or
• Ftr/ftr-<somedescription> or
• etc.

Using Tower as my git front end, it neatly organizes all the Ftr/, Fix/, Test/ etc. into folders.
Once I am done with a branch, I rename them to Done/...-<description>.

That way they are still there (which can be handy to provide history) and I can always go back knowing what it was (feature, fix, test, etc.)

Serialization means persisting objects in java. If you want to save the state of the object and want to rebuild the state later (may be in another JVM) serialization can be used.

Note that the properties of an object is only going to be saved. If you want to resurrect the object again you should have the class file, because the member variables only will be stored and not the member functions.

eg:

ObjectInputStream oos = new ObjectInputStream(                                 
                                 new FileInputStream(  new File("o.ser")) ) ;
SerializationSample SS = (SearializationSample) oos.readObject();

The Searializable is a marker interface which marks that your class is serializable. Marker interface means that it is just an empty interface and using that interface will notify the JVM that this class can be made serializable.

I think its better to to do text-align center for div and let image take care of the height. Just specify a top and bottom padding for div to have space between image and div. Look at this example: http://jsfiddle.net/Tv9mG/

Please change your javascript function as like below....

$(function () {
        $("#projectKey").change(function () {
            alert($('option:selected').text());
        });
    });

You do not need to use $(this) in alert.

Be very careful with whitespace and other stuff that may affect the "output" already done. I certainly know this but still suffered from the same problem. My whole "Admin.php"-file had some spaces after the closing php-tag ?> down the bottom on the last row :)

Easily discovered by adding...

error_reporting(E_ALL);

...which told me which line of code that generated the output.

I'm not aware of anything like a single table that lets you compare all of them in at one glance (I'm not sure such a table would even be feasible).

Of course the ISO standard document enumerates the complexity requirements in detail, sometimes in various rather readable tables, other times in less readable bullet points for each specific method.

Also the STL library reference at http://www.cplusplus.com/reference/stl/ provides the complexity requirements where appropriate.

Oh my God. not need to do anything special. only in your post section do as follows:

    $.post(yourURL,{ '': results})(function(e){ ...}

In server use this:

   public ActionResult MethodName(List<yourViewModel> model){...}

Assuming that a is a vector, remove the contiguous duplicates using

a.erase(unique(a.begin(),a.end()),a.end()); runs in O(n) time.

Try this:

1. Dump the innerHTML of the container into the iFrame (plus any print-specific CSS
2. print the iFrame contents.

Try it out in JSFiddle (iframes don't appear to work in StackOverflow's preview)

You can see the code here, but it won't work due to what are probably security limitations in StackOverflow's renderer.

const printButton = document.getElementById('print-button');

printButton.addEventListener('click', event => {
  // build the new HTML page
  const content = document.getElementById('name-card').innerHTML;
  const printHtml = `<html>
      <head>
          <meta charset="utf-8">
          <title>Name Card</title>
      </head>
      <body>${content}</body>
  </html>`;
      
  // get the iframe
  let iFrame = document.getElementById('print-iframe');
  
  // set the iFrame contents and print
  iFrame.contentDocument.body.innerHTML = printHtml;
  iFrame.focus();
    iFrame.contentWindow.print();

I think You are trying to use the normal URL of video Like this :

Copying Direct URL from YouTube

That doesn't let you display the content on other domains.To Tackle this up , You should use the Copy Embed Code feature provided by the YouTube itself .Like this :

Copy Embed Code ( YouTube )

That would free you up from any issues .

For the above Scenario :

• Go to Youtube Video

• Copy Embed Code

• Paste that into your Code ( Make sure you Escape all the " ( Inverted Commas) by \" .

One use for the 'Unary Scope Resolution Operator' or 'Colon Colon Operator' is for local and global variable selection of identical names:

    #include <iostream>
    using namespace std;
    
    int variable = 20;
    
    int main()
    {
    float variable = 30;
    
    cout << "This is local to the main function: " << variable << endl;
    cout << "This is global to the main function: " << ::variable << endl;
    
    return 0;
    }

The resulting output would be:

This is local to the main function: 30

This is global to the main function: 20

Other uses could be: Defining a function from outside of a class, to access a static variable within a class or to use multiple inheritance.

If you're not in an activity you can use the static from() method from the LayoutInflater class to get a LayoutInflater, or request the service from the context method getSystemService() too :

LayoutInflater i;
Context x;       //Assuming here that x is a valid context, not null

i = (LayoutInflater) x.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//OR
i = LayoutInflater.from(x);

(I know it's almost 4 years ago but still worth mentioning)

string[] str = new string[]{"1","2"};
string[] str = new string[4];

In my memory, excel (versions >= 2007) limits the power 2 of 20: 1.048.576 lines.

Csv is over to this boundary, like ordinary text file. So you will be care of the transfer between two formats.

This answer is pretty similar to Oz.'s, using <chrono> for C++ -- I didn't grab it from Oz. though...

I picked up the original snippet at the bottom of this page, and slightly modified it to be a complete console app. I love using this lil' ol' thing. It's fantastic if you do a lot of scripting and need a reliable tool in Windows to get the epoch in actual milliseconds without resorting to using VB, or some less modern, less reader-friendly code.

#include <chrono>
#include <iostream>

int main() {
    unsigned __int64 now = std::chrono::duration_cast<std::chrono::milliseconds>(std::chrono::system_clock::now().time_since_epoch()).count();
    std::cout << now << std::endl;
    return 0;
}

Assume, selectDrop is the class present in your HTML tag.So, this much of code is enough to change default arrow icon:

.selectDrop{
      background: url(../images/icn-down-arrow-light.png) no-repeat right #ddd; /*To change default icon with provided image*/
      -webkit-appearance:none; /*For hiding default pointer of drop-down on Chrome*/
      -moz-appearance:none; /*For hiding default pointer of drop-down on Mozilla*/
      background-position-x: 90%; /*Adjust according to width of dropdown*/
    }

This seems to work: /(\{(?:\{.*\}|[^\{])*\})/m

You can achieve this easily using

    shortString = longString.substring(0, Math.min(s.length(), MAX_LENGTH));

You use the lpMultiByteStr [out] parameter by creating a new char array. You then pass this char array in to get it filled. You only need to initialize the length of the string + 1 so that you can have a null terminated string after the conversion.

Here are a couple of useful helper functions for you, they show the usage of all parameters.

#include <string>

std::string wstrtostr(const std::wstring &wstr)
{
    // Convert a Unicode string to an ASCII string
    std::string strTo;
    char *szTo = new char[wstr.length() + 1];
    szTo[wstr.size()] = '\0';
    WideCharToMultiByte(CP_ACP, 0, wstr.c_str(), -1, szTo, (int)wstr.length(), NULL, NULL);
    strTo = szTo;
    delete[] szTo;
    return strTo;
}

std::wstring strtowstr(const std::string &str)
{
    // Convert an ASCII string to a Unicode String
    std::wstring wstrTo;
    wchar_t *wszTo = new wchar_t[str.length() + 1];
    wszTo[str.size()] = L'\0';
    MultiByteToWideChar(CP_ACP, 0, str.c_str(), -1, wszTo, (int)str.length());
    wstrTo = wszTo;
    delete[] wszTo;
    return wstrTo;
}

--

Anytime in documentation when you see that it has a parameter which is a pointer to a type, and they tell you it is an out variable, you will want to create that type, and then pass in a pointer to it. The function will use that pointer to fill your variable.

So you can understand this better:

//pX is an out parameter, it fills your variable with 10.
void fillXWith10(int *pX)
{
  *pX = 10;
}

int main(int argc, char ** argv)
{
  int X;
  fillXWith10(&X);
  return 0;
}

Helping you further, where Mick Sharpe left you:

It's deriveration is quite simple: see http://en.wikipedia.org/wiki/Logarithm -> Group Theory

log(n!) = log(n * (n-1) * (n-2) * ... * 2 * 1) = log(n) + log(n-1) + ... + log(2) + log(1)

Think of n as infinitly big. What is infinite minus one? or minus two? etc.

log(inf) + log(inf) + log(inf) + ... = inf * log(inf)

And then think of inf as n.

For some reason, there is no option in the create page dialogue to select a master page. I have tried both programatically declaring the MP and by updating the property in the Properties pane. – NoCarrier 13 mins ago

I believe its because i'm using a "web application" vs a "web site" – NoCarrier 9 mins ago

Chances are it is in the <@PAGE> tag where your problem is. That said, it doesnt make a difference if you are using a Web Application or not. To create a Child Page, right click on your master page in the Solution Explorer and choose Add Content Page.

In Xcode 8, Swift 3.0

Steps:

1. Get the Type:

Option 1:

let type : Type = MyClass.self  //Determines Type from Class

Option 2:

let type : Type = type(of:self) //Determines Type from self

2. Convert Type to String:

let string : String = "\(type)" //String

const mongoose = require("mongoose");

mongoose.connect('mongodb://localhost:27017/Edureka',{ useNewUrlParser: true, useUnifiedTopology: true }, (error)=> {
    const connectionStatus = !error ? 'Success': 'Error Connecting to database';
    console.log(connectionStatus);
});

I just updated matplotlib to 1.1.0 on my system and it now allows me to save to jpg with savefig.

To upgrade to matplotlib 1.1.0 with pip, use this command:

pip install -U 'http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-1.1.0/matplotlib-1.1.0.tar.gz/download'

EDIT (to respond to comment):

pylab is simply an aggregation of the matplotlib.pyplot and numpy namespaces (as well as a few others) jinto a single namespace.

On my system, pylab is just this:

from matplotlib.pylab import *
import matplotlib.pylab
__doc__ = matplotlib.pylab.__doc__

You can see that pylab is just another namespace in your matplotlib installation. Therefore, it doesn't matter whether or not you import it with pylab or with matplotlib.pyplot.

If you are still running into problem, then I'm guessing the macosx backend doesn't support saving plots to jpg. You could try using a different backend. See here for more information.

This error happens when the branch you are switching to, has changes that your current branch doesn't have.

If you are seeing this error when you try to switch to a new branch, then your current branch is probably behind one or more commits. If so, run:

git fetch

You should also remove dependencies which may also conflict with the destination branch.

For example, for iOS developers:

pod deintegrate

then try checking out a branch again.

If the desired branch isn't new you can either cherry pick a commit and fix the conflicts or stash the changes and then fix the conflicts.

1. Git Stash (recommended)

git stash
git checkout <desiredBranch>
git stash apply

2. Cherry pick (more work)

git add <your file>
git commit -m "Your message"
git log

Copy the sha of your commit. Then discard unwanted changes:

git checkout .
git checkout -- . 
git clean -f -fd -fx

Make sure your branch is up to date:

git fetch

Then checkout to the desired branch

git checkout <desiredBranch>

Then cherry pick the other commit:

git cherry-pick <theSha>

Now fix the conflict.

3. Otherwise, your other option is to abandon your current branches changes with:

git checkout -f branch

If you are looking for a one-size-fits-all, I'd suggest DECIMAL(19, 4) is a popular choice (a quick Google bears this out). I think this originates from the old VBA/Access/Jet Currency data type, being the first fixed point decimal type in the language; Decimal only came in 'version 1.0' style (i.e. not fully implemented) in VB6/VBA6/Jet 4.0.

The rule of thumb for storage of fixed point decimal values is to store at least one more decimal place than you actually require to allow for rounding. One of the reasons for mapping the old Currency type in the front end to DECIMAL(19, 4) type in the back end was that Currency exhibited bankers' rounding by nature, whereas DECIMAL(p, s) rounded by truncation.

An extra decimal place in storage for DECIMAL allows a custom rounding algorithm to be implemented rather than taking the vendor's default (and bankers' rounding is alarming, to say the least, for a designer expecting all values ending in .5 to round away from zero).

Yes, DECIMAL(24, 8) sounds like overkill to me. Most currencies are quoted to four or five decimal places. I know of situations where a decimal scale of 8 (or more) is required but this is where a 'normal' monetary amount (say four decimal places) has been pro rata'd, implying the decimal precision should be reduced accordingly (also consider a floating point type in such circumstances). And no one has that much money nowadays to require a decimal precision of 24 :)

However, rather than a one-size-fits-all approach, some research may be in order. Ask your designer or domain expert about accounting rules which may be applicable: GAAP, EU, etc. I vaguely recall some EU intra-state transfers with explicit rules for rounding to five decimal places, therefore using DECIMAL(p, 6) for storage. Accountants generally seem to favour four decimal places.

PS Avoid SQL Server's MONEY data type because it has serious issues with accuracy when rounding, among other considerations such as portability etc. See Aaron Bertrand's blog.

Microsoft and language designers chose banker's rounding because hardware designers chose it [citation?]. It is enshrined in the Institute of Electrical and Electronics Engineers (IEEE) standards, for example. And hardware designers chose it because mathematicians prefer it. See Wikipedia; to paraphrase: The 1906 edition of Probability and Theory of Errors called this 'the computer's rule' ("computers" meaning humans who perform computations).

As of October 2016, Google has added a file upload question type in native Google Forms, no Google Apps Script needed. See documentation.

You could just use position relative and set a height on the parent

.fake-legend {_x000D_
  height: 15px;_x000D_
  width:100%;_x000D_
  border-bottom: solid 2px #000;_x000D_
  text-align: center;_x000D_
  margin: 2em 0;_x000D_
}_x000D_
.fake-legend span {_x000D_
  background: #fff;_x000D_
  position: relative;_x000D_
  top: 0;_x000D_
  padding: 0 20px;_x000D_
  line-height:30px;_x000D_
}

<p class="fake-legend"><span>Or</span>_x000D_
</p>

In my case:

<html>
 <head>
  <script type="text/javascript">

    function changeFunction(val) {

       //Show option value
       console.log(val.value);
    }

  </script>
 </head>
 <body>
   <select id="selectBox" onchange="changeFunction(this)">
     <option value="1">Option #1</option>
     <option value="2">Option #2</option>
   </select>
 </body>
</html>

If you want to fake a $_GET (or a $_POST) when including a file, you can use it like you would use any other var, like that:

$_GET['key'] = 'any get value you want';
include('your_other_file.php');

    // acos(0.0) will return value of pi/2, inverse of cos(0) is pi/2 
    double pi = 2 * acos(0.0);
    int n; // upto 6 digit
    scanf("%d",&n); //precision with which you want the value of pi
    printf("%.*lf\n",n,pi); // * will get replaced by n which is the required precision

Update 11.05.2020:
Modified to include static fields and methods to closer replicate "true" enum behavior.

If you're planning on updating I would recommend trying to use what I call an "Enum Class" (barring any browser or runtime env limitations you can't accept). It's basically a very simple and clean class that uses private fields and limited accessors to simulate the behavior of an enum. This is something I sometimes do in C# when I want to build more functionality into an enum.

I realize private class fields are still experimental at this point but it seems to work for the purposes of creating a class with immutable fields/properties. Browser support is decent as well. The only "major" browsers that don't support it are Firefox (which I'm sure they will soon) and IE (who cares).

DISCLAIMER:
I am not a developer. I just put this together to solve the limitations of nonexistent enums in JS when I was working on a personal project.

Sample Class

class Colors {
    // Private Fields
    static #_RED = 0;
    static #_GREEN = 1;
    static #_BLUE = 2;

    // Accessors for "get" functions only (no "set" functions)
    static get RED() { return this.#_RED; }
    static get GREEN() { return this.#_GREEN; }
    static get BLUE() { return this.#_BLUE; }
}

You should now be able to call your enums directly.

Colors.RED; // 0
Colors.GREEN; // 1
Colors.BLUE; // 2

The combination of using private fields and limited accessors means that the existing enum values are well protected (they're essentially constants now).

Colors.RED = 10 // Colors.RED is still 0
Colors._RED = 10 // Colors.RED is still 0
Colors.#_RED = 10 // Colors.RED is still 0

If you offer cbind a set of arguments all of whom are vectors, you will get not a dataframe, but rather a matrix, in this case an all character matrix. They have different features. You can get a dataframe if some of your arguments remain dataframes, Try:

merger <- cbind(Date =as.character(Date),
             weather1[ , c("High", "Low", "Avg..High", "Avg.Low")] , 
             ScnMov =sale$Scanned.Movement[a] )

An alternative solution:

div[class|='tocolor'] will match for values of the "class" attribute that begin with "tocolor-", including "tocolor-1", "tocolor-2", etc.

Beware that this won't match

<div class="foo tocolor-">

Reference: https://www.w3.org/TR/css3-selectors/#attribute-representation

[att|=val]

Represents an element with the att attribute, its value either being exactly "val" or beginning with "val" immediately followed by "-" (U+002D)

Use cd in a subshell; the shorthand way to use this kind of subshell is parentheses.

(cd wherever; mycommand ...)

That said, if your command has an environment that it requires, it should really ensure that environment itself instead of putting the onus on anything that might want to use it (unless it's an internal command used in very specific circumstances in the context of a well defined larger system, such that any caller already needs to ensure the environment it requires). Usually this would be some kind of shell script wrapper.

The headers are entirely encrypted. The only information going over the network 'in the clear' is related to the SSL setup and D/H key exchange. This exchange is carefully designed not to yield any useful information to eavesdroppers, and once it has taken place, all data is encrypted.

var app = angular.module('myapp', []);

app.filter('htmlToPlaintext', function()
{
    return function(text)
    {
        return  text ? String(text).replace(/<[^>]+>/gm, '') : '';
    };
});

setRetainInstance(boolean) is useful when you want to have some component which is not tied to Activity lifecycle. This technique is used for example by rxloader to "handle Android's activity lifecyle for rxjava's Observable" (which I've found here).

I know it was not available at the time, but now you could also use Anaconda navigator to install a specific version of packages in the environments tab.

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

How to copy selected files from Android with adb pull

That should be simple. Try this:

var idList = new int[1, 2, 3, 4, 5];
var userProfiles = _dataContext.UserProfile.Where(e => idList.Contains(e));

When running tomcat out of eclipse it won't pick the lib set in CATALINA_HOME/lib, there are two ways to fix it. Double click on Tomcat server in eclipse servers view, it will open the tomcat plugin config, then either:

1. Click on "Open Launch Config" > Classpath tab set the mysql connector/j jar location. or
2. Server Location > select option which says "Use Tomcat installation (take control of Tomcat installation)"

Besides installing the required packages, I also needed to manually add PostgreSQL bin directory to PATH.
$vi ~/.bash_profile
Add PATH=/usr/pgsql-9.2/bin:$PATH before export PATH.
$source ~/.bash_profile
$pip install psycopg2

Old question, but there's an easier way.

sns.pointplot(x=x_col,y=y_col,data=df_1,color='blue')
sns.pointplot(x=x_col,y=y_col,data=df_2,color='green')
sns.pointplot(x=x_col,y=y_col,data=df_3,color='red')
plt.legend(labels=['legendEntry1', 'legendEntry2', 'legendEntry3'])

This lets you add the plots sequentially, and not have to worry about any of the matplotlib crap besides defining the legend items.

A HANDLE in Win32 programming is a token that represents a resource that is managed by the Windows kernel. A handle can be to a window, a file, etc.

Handles are simply a way of identifying a particulate resource that you want to work with using the Win32 APIs.

So for instance, if you want to create a Window, and show it on the screen you could do the following:

// Create the window
HWND hwnd = CreateWindow(...); 
if (!hwnd)
   return; // hwnd not created

// Show the window.
ShowWindow(hwnd, SW_SHOW);

In the above example HWND means "a handle to a window".

If you are used to an object oriented language you can think of a HANDLE as an instance of a class with no methods who's state is only modifiable by other functions. In this case the ShowWindow function modifies the state of the Window HANDLE.

See Handles and Data Types for more information.

In XML there can be only one root element - you have two - heading and song.

If you restructure to something like:

<?xml version="1.0" encoding="UTF-8"?>
<song> 
 <heading>
 The Twelve Days of Christmas
 </heading>
 ....
</song>

The error about well-formed XML on the root level should disappear (though there may be other issues).

You may also consider the ToolStripButton control if you don't mind hosting it in a ToolStripContainer. I think it can natively support pressed and unpressed states.

Use Fail module.

1. Use ignore_errors with every task that you need to ignore in case of errors.
2. Set a flag (say, result = false) whenever there is a failure in any task execution
3. At the end of the playbook, check if flag is set, and depending on that, fail the execution

- fail: msg="The execution has failed because of errors."
  when: flag == "failed"

Update:

Use register to store the result of a task like you have shown in your example. Then, use a task like this:

- name: Set flag
  set_fact: flag = failed
  when: "'FAILED' in command_result.stderr"

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

Hidden Field :

<input type="hidden" name="year" id="year">

Script :

<script type="text/javascript">
     var year = new Date();
     document.getElementById("year").value=(year.getFullYear());
</script>

<TextView
 android:id="@+id/phoneNumber"
 android:autoLink="phone"
 android:linksClickable="true"
 android:text="+91 22 2222 2222"
 />

This is how you can open EditText label assigned number on dialer directly.

It is simple: if recv() returns 0 bytes; you will not receive any more data on this connection. Ever. You still might be able to send.

It means that your non-blocking socket have to raise an exception (it might be system-dependent) if no data is available but the connection is still alive (the other end may send).

You must check the certificate hash code.

ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain,
    errors) =>
        {
            var hashString = certificate.GetCertHashString();
            if (hashString != null)
            {
                var certHashString = hashString.ToLower();
                return certHashString == "dec2b525ddeemma8ccfaa8df174455d6e38248c5";
            }
            return false;
        };

Share application with title is you app_name, content is your application link

private static void shareApp(Context context) {
    final String appPackageName = BuildConfig.APPLICATION_ID;
    final String appName = context.getString(R.string.app_name);
    Intent shareIntent = new Intent(Intent.ACTION_SEND);
    shareIntent.setType("text/plain");
    String shareBodyText = "https://play.google.com/store/apps/details?id=" +
            appPackageName;
    shareIntent.putExtra(Intent.EXTRA_SUBJECT, appName);
    shareIntent.putExtra(Intent.EXTRA_TEXT, shareBodyText);
    context.startActivity(Intent.createChooser(shareIntent, context.getString(R.string
            .share_with)));
}

var myItem = myList.Find(item => item.property == "something");

The following snippet solved the issue for me:

class FigureWrapper(object):
    '''Frees underlying figure when it goes out of scope. 
    '''

    def __init__(self, figure):
        self._figure = figure

    def __del__(self):
        plt.close(self._figure)
        print("Figure removed")


# .....
    f, ax = plt.subplots(1, figsize=(20, 20))
    _wrapped_figure = FigureWrapper(f)

    ax.plot(...
    plt.savefig(...
# .....

When _wrapped_figure goes out of scope the runtime calls our __del__() method with plt.close() inside. It happens even if exception fires after _wrapped_figure constructor.

In addition to what Angular University said above you may want to use @Import to aggregate @Configuration classes to the other class (AuthenticationController in my case) :

@Import(SecurityConfig.class)
@RestController
public class AuthenticationController {
@Autowired
private AuthenticationManager authenticationManager;
//some logic
}

Spring doc about Aggregating @Configuration classes with @Import: link

It is specific from your driver. You need to supply a parameter in your Java program to tell it the time zone you want to use.

java -Duser.timezone="America/New_York" GetCurrentDateTimeZone

Further this:

to_char(new_time(sched_start_time, 'CURRENT_TIMEZONE', 'NEW_TIMEZONE'), 'MM/DD/YY HH:MI AM')

May also be of value in handling the conversion properly. Taken from here

adding my answer too, someone might find it useful or may be correct mine too.

function getInteger(int){
  var regx = /^[-+]?[\d.]+$/g;
  return regx.test(int);
}


alert(getInteger('-11.11'));

If you are talking about test/dev environments, then just use the debug option. It will auto-reload the flask app when a code change happens.

app.run(debug=True)

Or, from the shell:

$ export FLASK_DEBUG=1
$ flask run

( Side note: This fills up the DOM if you have a lot of data on both levels, so I am therefore working on a directive to fetch data and replace, i.e. adding into DOM when clicking parent and removing when another is clicked or same parent again. To get the kind of behavior you find on Prisjakt.nu, if you scroll down to the computers listed and click on the row (not the links). If you do that and inspect elements you will see that a tr is added and then removed if parent is clicked again or another. )

You can use rsplit

string.rsplit('delimeter',1)[1]

To get the string from reverse.

I'm adding another option. The answers above were very useful for me, but I wanted to use jQuery instead of ic-ajax (it seems to have a dependency with Ember when I tried to install through bower). Keep in mind that this solution only works on modern browsers.

In order to implement this on jQuery I used jQuery BinaryTransport. This is a nice plugin to read AJAX responses in binary format.

Then you can do this to download the file and send the headers:

$.ajax({
    url: url,
    type: 'GET',
    dataType: 'binary',
    headers: headers,
    processData: false,
    success: function(blob) {
        var windowUrl = window.URL || window.webkitURL;
        var url = windowUrl.createObjectURL(blob);
        anchor.prop('href', url);
        anchor.prop('download', fileName);
        anchor.get(0).click();
        windowUrl.revokeObjectURL(url);
    }
});

The vars in the above script mean:

• url: the URL of the file
• headers: a Javascript object with the headers to send
• fileName: the filename the user will see when downloading the file
• anchor: it is a DOM element that is needed to simulate the download that must be wrapped with jQuery in this case. For example $('a.download-link').

You can use the <pre> tag with innerHTML. The HTML <pre> element represents preformatted text which is to be presented exactly as written in the HTML file. The text is typically rendered using a non-proportional ("monospace") font. Whitespace inside this element is displayed as written. If you don't want a different font, simply add pre as a selector in your CSS file and style it as desired.

Ex:

var a = '<pre>something        something</pre>';
document.body.innerHTML = a;

Use the HTML iframe frameborder Attribute

http://www.w3schools.com/tags/att_iframe_frameborder.asp

Note: use frameBorder (cap B) for IE, otherwise will not work. But, the iframe frameborder attribute is not supported in HTML5. So, Use CSS instead.

<iframe src="http://example.org" width="200" height="200" style="border:0">

you can also remove scrolling using scrolling attribute http://www.w3schools.com/tags/att_iframe_scrolling.asp

<iframe src="http://example.org" width="200" height="200" scrolling="no" style="border:0">

Also you can use seamless attribute which is new in HTML5. The seamless attribute of the iframe tag is only supported in Opera, Chrome and Safari. When present, it specifies that the iframe should look like it is a part of the containing document (no borders or scrollbars). As of now, The seamless attribute of the tag is only supported in Opera, Chrome and Safari. But in near future it will be the standard solution and will be compatible with all browsers. http://www.w3schools.com/tags/att_iframe_seamless.asp

ITNOA

You can use C++ function for doing this.

 std::string repeat(const std::string& input, size_t num)
 {
    std::ostringstream os;
    std::fill_n(std::ostream_iterator<std::string>(os), num, input);
    return os.str();
 }

I think I got the reason for the above error. It is the corporate proxy(virtual private network) provided in order to work in the client network. Without that connection I frequently faced the same problem be it maven build or npm install.

From http://msdn.microsoft.com/en-us/library/ms176089.aspx

varchar [ ( n | max ) ] Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.

1 character = 1 byte. And don't forget 2 bytes for the termination. So, 2^31-3 characters.

Here is the documentation of <select>. You are using 2 attributes:

multiple
This Boolean attribute indicates that multiple options can be selected in the list. If it is not specified, then only one option can be selected at a time. When multiple is specified, most browsers will show a scrolling list box instead of a single line dropdown.

size
If the control is presented as a scrolling list box (e.g. when multiple is specified), this attribute represents the number of rows in the list that should be visible at one time. Browsers are not required to present a select element as a scrolled list box. The default value is 0.

As described in the docs. <select size="1" multiple> will render a List box only 1 line visible and a scrollbar. So you are loosing the dropdown/arrow with the multiple attribute.

I found a good example showing the differences between all hibernate save methods:

http://www.journaldev.com/3481/hibernate-session-merge-vs-update-save-saveorupdate-persist-example

In brief, according to the above link:

save()

• We can invoke this method outside a transaction. If we use this without transaction and we have cascading between entities, then only the primary entity gets saved unless we flush the session.
• So, if there are other objects mapped from the primary object, they gets saved at the time of committing transaction or when we flush the session.

persist()

• Its similar to using save() in transaction, so it’s safe and takes care of any cascaded objects.

saveOrUpdate()

• Can be used with or without the transaction, and just like save(), if its used without the transaction, mapped entities wont be saved un;ess we flush the session.

• Results into insert or update queries based on the provided data. If the data is present in the database, update query is executed.

update()

• Hibernate update should be used where we know that we are only updating the entity information. This operation adds the entity object to persistent context and further changes are tracked and saved when transaction is committed.
• Hence even after calling update, if we set any values in the entity,they will be updated when transaction commits.

merge()

• Hibernate merge can be used to update existing values, however this method create a copy from the passed entity object and return it. The returned object is part of persistent context and tracked for any changes, passed object is not tracked. This is the major difference with merge() from all other methods.

Also for practical examples of all these, please refer to the link I mentioned above, it shows examples for all these different methods.

You could replace any view at any time.

int optionId = someExpression ? R.layout.option1 : R.layout.option2;

View C = findViewById(R.id.C);
ViewGroup parent = (ViewGroup) C.getParent();
int index = parent.indexOfChild(C);
parent.removeView(C);
C = getLayoutInflater().inflate(optionId, parent, false);
parent.addView(C, index);

If you don't want to replace already existing View, but choose between option1/option2 at initialization time, then you could do this easier: set android:id for parent layout and then:

ViewGroup parent = (ViewGroup) findViewById(R.id.parent);
View C = getLayoutInflater().inflate(optionId, parent, false);
parent.addView(C, index);

You will have to set "index" to proper value depending on views structure. You could also use a ViewStub: add your C view as ViewStub and then:

ViewStub C = (ViewStub) findViewById(R.id.C);
C.setLayoutResource(optionId);
C.inflate();

That way you won't have to worry about above "index" value if you will want to restructure your XML layout.

The port number is an unsigned 16-bit integer, so 65535.

Most of the browsers doesn't support customizing of select tag using css. But I find this javascript which can be used to style select tag. But as usual no support for IE browsers.

http://ryanfait.com/resources/custom-checkboxes-and-radio-buttons/ I noticed an error on this that Onchange attribute dosen't work

public class RemoveCharsFromString {

static String testcase1 = "No, I am going to Noida";
static String testcase2 = "goings";

public static void main(String args[])throws StringIndexOutOfBoundsException{
    RemoveCharsFromString testInstance= new RemoveCharsFromString();
    String result = testInstance.remove(testcase1,testcase2);
    System.out.println(result);
}

//write your code here
public String remove(String str, String str1)throws StringIndexOutOfBoundsException
    {   String result=null;


       if (str == null)
        return "";


    try
    {
     for (int i = 0; i < str1.length (); i++) 
    {


        char ch1=str1.charAt(i);
        for(int j=0;j<str.length();j++)
        {
            char ch = str.charAt (j);

        if (ch == ch1)
        {
        String s4=String.valueOf(ch);
        String s5= str.replaceAll(s4, "");
        str=s5;


        }
        }

    }
    }
    catch(Exception e)
    {

    }
    result=str;
    return result;
    }
 }

If you're using rails you can also use in_groups_of:

foo.in_groups_of(3)

• keras detailed guide to save models -> https://www.tensorflow.org/guide/keras/save_and_serialize

Checkpoints capture the exact value of all parameters (tf.Variable objects) used by a model. Checkpoints do not contain any description of the computation defined by the model and thus are typically only useful when source code that will use the saved parameter values is available.

The SavedModel format on the other hand includes a serialized description of the computation defined by the model in addition to the parameter values (checkpoint). Models in this format are independent of the source code that created the model. They are thus suitable for deployment via TensorFlow Serving, TensorFlow Lite, TensorFlow.js, or programs in other programming languages (the C, C++, Java, Go, Rust, C# etc. TensorFlow APIs).

Original blog post

The following code generates random data for the sake of the demonstration.

1. We start by creating the placeholders. They will hold the data at runtime. From them, we create the Dataset and then its Iterator. We get the iterator's generated tensor, called input_tensor which will serve as input to our model.
2. The model itself is built from input_tensor: a GRU-based bidirectional RNN followed by a dense classifier. Because why not.
3. The loss is a softmax_cross_entropy_with_logits, optimized with Adam. After 2 epochs (of 2 batches each), we save the "trained" model with tf.saved_model.simple_save. If you run the code as is, then the model will be saved in a folder called simple/ in your current working directory.
4. In a new graph, we then restore the saved model with tf.saved_model.loader.load. We grab the placeholders and logits with graph.get_tensor_by_name and the Iterator initializing operation with graph.get_operation_by_name.
5. Lastly we run an inference for both batches in the dataset, and check that the saved and restored model both yield the same values. They do!

                print('Restored values: ', restored_values[i][0])

    # Check if original inference and restored inference are equal
    valid = all((v == rv).all() for v, rv in zip(values, restored_values))
    print('\nInferences match: ', valid)

This will print:

Inferences match:  True

x / y

quotient of x and y

x // y 

(floored) quotient of x and y

Instead of printf("Error");, you should try perror("Error") which may print the actual reason of failure (like Permission Problem, Invalid Argument, etc).

Simple Solution,worked for me

public static byte[] serialize(Object obj) throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    ObjectOutputStream os = new ObjectOutputStream(out);
    os.writeObject(obj);
    return out.toByteArray();
}

Try this: parseInt(jQuery.offset().top, 10)

std::string + const char* results in another std::string. system does not take a std::string, and you cannot concatenate char*'s with the + operator. If you want to use the code this way you will need:

std::string name = "john";
std::string tmp = 
    "quickscan.exe resolution 300 selectscanner jpg showui showprogress filename '" + 
    name + ".jpg'";
system(tmp.c_str());

The top answer is useful but I expanded on it a bit.

If you want to set the value of your file object (the f in as f) based on the arguments passed to open() here's one way to do it:

def save_arg_return_data(*args, **kwargs):
    mm = MagicMock(spec=file)
    mm.__enter__.return_value = do_something_with_data(*args, **kwargs)
    return mm
m = MagicMock()
m.side_effect = save_arg_return_array_of_data

# if your open() call is in the file mymodule.animals 
# use mymodule.animals as name_of_called_file
open_name = '%s.open' % name_of_called_file

with patch(open_name, m, create=True):
    #do testing here

Basically, open() will return an object and with will call __enter__() on that object.

To mock properly, we must mock open() to return a mock object. That mock object should then mock the __enter__() call on it (MagicMock will do this for us) to return the mock data/file object we want (hence mm.__enter__.return_value). Doing this with 2 mocks the way above allows us to capture the arguments passed to open() and pass them to our do_something_with_data method.

I passed an entire mock file as a string to open() and my do_something_with_data looked like this:

def do_something_with_data(*args, **kwargs):
    return args[0].split("\n")

This transforms the string into a list so you can do the following as you would with a normal file:

for line in file:
    #do action

This is working fine to me with YT player

 createPlayer(): void {
  return new window['YT'].Player(this.youtube.playerId, {
  height: this.youtube.playerHeight,
  width: this.youtube.playerWidth,
  playerVars: {
    rel: 0,
    showinfo: 0
  }
});
}

this.youtube.player.pauseVideo();

You can use a FileReader object to read text file here is example code:

  <div id="page-wrapper">

        <h1>Text File Reader</h1>
        <div>
            Select a text file: 
            <input type="file" id="fileInput">
        </div>
        <pre id="fileDisplayArea"><pre>

    </div>
<script>
window.onload = function() {
        var fileInput = document.getElementById('fileInput');
        var fileDisplayArea = document.getElementById('fileDisplayArea');

        fileInput.addEventListener('change', function(e) {
            var file = fileInput.files[0];
            var textType = /text.*/;

            if (file.type.match(textType)) {
                var reader = new FileReader();

                reader.onload = function(e) {
                    fileDisplayArea.innerText = reader.result;
                }

                reader.readAsText(file);    
            } else {
                fileDisplayArea.innerText = "File not supported!"
            }
        });
}

</script>

Here is the codepen demo

If you have a fixed file to read every time your application load then you can use this code :

<script>
var fileDisplayArea = document.getElementById('fileDisplayArea');
function readTextFile(file)
{
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function ()
    {
        if(rawFile.readyState === 4)
        {
            if(rawFile.status === 200 || rawFile.status == 0)
            {
                var allText = rawFile.responseText;
                fileDisplayArea.innerText = allText 
            }
        }
    }
    rawFile.send(null);
}

readTextFile("file:///C:/your/path/to/file.txt");
</script>

The easiest way to do this is:

list.sort(key = lambda x:len(x))

Here are the three web pages on which we found the answer. The most difficult part was setting up static ports for SQLEXPRESS.

Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.

How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.

How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.

You can easily Use this command:

// Question : name of Model
// take 10 rows from DB In shuffle records...

$questions = Question::orderByRaw('RAND()')->take(10)->get();

Try changing it to.

 Response.Clear();
 Response.ClearHeaders();
 Response.ClearContent();
 Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name);
 Response.AddHeader("Content-Length", file.Length.ToString());
 Response.ContentType = "text/plain";
 Response.Flush();
 Response.TransmitFile(file.FullName);
 Response.End();

Look for this on your Manifest.xml android:icon="@drawable/ic_launcher" then change the ic_launcher to the name of your icon which is on your @drawable folder.
