You can just use

cd C:/Users/../..

        if(data.length==0){
            alert("empty");
              $('#MembershipTable > tbody').empty();
            // $('#MembershipTable').dataTable().fnDestroy();
                    $('#MembershipTable_info').empty(); 
                    $("#MembershipTable_length").empty();
                    $("#MembershipTable_paginate").empty();

             html="<tr><td colspan='20'><b>No data available in Table</b> </td></tr>";
           $("#MembershipTable").append(html);
        }

        else{
             $('#MembershipTable').dataTable().fnDestroy();
            $('#MembershipTable > tbody').empty();

         for(var i=0; i<data.length; i++){
            //

.......}

I posted a solution using IBInspectable, so you can change the max length value both in interface builder or programmatically. Check it out here

Press CTRL+F11 to rotate the screen.

To create a DLL File, click on New project, then select Class Library.

Enter your code into the class file that was automatically created for you and then click Build Solution from the Debug menu.

Now, look in your directory: ../debug/release/YOURDLL.dll

There it is! :)

P.S. DLL files cannot be run just like normal applciation (exe) files. You'll need to create a separate project (probably a win forms app) and then add your dll file to that project as a "Reference", you can do this by going to the Solution explorer, right clicking your project Name and selecting Add Reference then browsing to whereever you saved your dll file.

For more detail please click HERE

One statement can be written as such:

someValues.forEach(x => console.log(x));

or multiple statements can be enclosed in {} like this:

someValues.forEach(x => { let a = 2 + x; console.log(a); });

I assume that with interface you mean a C++ class with only pure virtual methods (i.e. without any code), instead with abstract class you mean a C++ class with virtual methods that can be overridden, and some code, but at least one pure virtual method that makes the class not instantiable. e.g.:

class MyInterface
{
public:
  // Empty virtual destructor for proper cleanup
  virtual ~MyInterface() {}

  virtual void Method1() = 0;
  virtual void Method2() = 0;
};


class MyAbstractClass
{
public:
  virtual ~MyAbstractClass();

  virtual void Method1();
  virtual void Method2();
  void Method3();

  virtual void Method4() = 0; // make MyAbstractClass not instantiable
};

In Windows programming, interfaces are fundamental in COM. In fact, a COM component exports only interfaces (i.e. pointers to v-tables, i.e. pointers to set of function pointers). This helps defining an ABI (Application Binary Interface) that makes it possible to e.g. build a COM component in C++ and use it in Visual Basic, or build a COM component in C and use it in C++, or build a COM component with Visual C++ version X and use it with Visual C++ version Y. In other words, with interfaces you have high decoupling between client code and server code.

Moreover, when you want to build DLL's with a C++ object-oriented interface (instead of pure C DLL's), as described in this article, it's better to export interfaces (the "mature approach") instead of C++ classes (this is basically what COM does, but without the burden of COM infrastructure).

I'd use an interface if I want to define a set of rules using which a component can be programmed, without specifying a concrete particular behavior. Classes that implement this interface will provide some concrete behavior themselves.

Instead, I'd use an abstract class when I want to provide some default infrastructure code and behavior, and make it possible to client code to derive from this abstract class, overriding the pure virtual methods with some custom code, and complete this behavior with custom code. Think for example of an infrastructure for an OpenGL application. You can define an abstract class that initializes OpenGL, sets up the window environment, etc. and then you can derive from this class and implement custom code for e.g. the rendering process and handling user input:

// Abstract class for an OpenGL app.
// Creates rendering window, initializes OpenGL; 
// client code must derive from it 
// and implement rendering and user input.
class OpenGLApp
{
public:
  OpenGLApp();
  virtual ~OpenGLApp();
  ...

  // Run the app    
  void Run();


  // <---- This behavior must be implemented by the client ---->

  // Rendering
  virtual void Render() = 0;

  // Handle user input
  // (returns false to quit, true to continue looping)
  virtual bool HandleInput() = 0;

  // <--------------------------------------------------------->


private:
  //
  // Some infrastructure code
  //
  ... 
  void CreateRenderingWindow();
  void CreateOpenGLContext();
  void SwapBuffers();
};


class MyOpenGLDemo : public OpenGLApp
{
public:
  MyOpenGLDemo();
  virtual ~MyOpenGLDemo();

  // Rendering
  virtual void Render();  // implements rendering code

  // Handle user input
  virtual bool HandleInput(); // implements user input handling


  //  ... some other stuff
};

Below is example to call synchronously but you can easily change to async by using await-sync:

var pairs = new List<KeyValuePair<string, string>>
            {
                new KeyValuePair<string, string>("login", "abc")
            };

var content = new FormUrlEncodedContent(pairs);

var client = new HttpClient {BaseAddress = new Uri("http://localhost:6740")};

    // call sync
var response = client.PostAsync("/api/membership/exist", content).Result; 
if (response.IsSuccessStatusCode)
{
}

In my case, it was due to an input in an array at an index equal to the length of the array.

string x[5];

for(int i=1; i<=5; i++){

    cin>>x[i];

}

x[5] is being accessed which is not present.

I think this is what you're looking for...

>>> import datetime
>>> dt = datetime.datetime.now()
>>> dt = dt.replace(hour=0, minute=0, second=0, microsecond=0) # Returns a copy
>>> dt
datetime.datetime(2011, 3, 29, 0, 0)

But if you really don't care about the time aspect of things, then you should really only be passing around date objects...

>>> d_truncated = datetime.date(dt.year, dt.month, dt.day)
>>> d_truncated
datetime.date(2011, 3, 29)

Yes we can. get familiar with Mono Project and read this article to get started.

if you want read and write on your extra field, you can use a new custom serializer, that extends serializers.Serializer, and use it like this

class ExtraFieldSerializer(serializers.Serializer):
    def to_representation(self, instance): 
        # this would have the same as body as in a SerializerMethodField
        return 'my logic here'

    def to_internal_value(self, data):
        # This must return a dictionary that will be used to
        # update the caller's validation data, i.e. if the result
        # produced should just be set back into the field that this
        # serializer is set to, return the following:
        return {
          self.field_name: 'Any python object made with data: %s' % data
        }

class MyModelSerializer(serializers.ModelSerializer):
    my_extra_field = ExtraFieldSerializer(source='*')

    class Meta:
        model = MyModel
        fields = ['id', 'my_extra_field']

i use this in related nested fields with some custom logic

Yes you can sort using query method in Spring Data.

Ex:ascending order or descending order by using the value of the id field.

Code:

  public interface StudentDAO extends JpaRepository<StudentEntity, Integer> {
    public findAllByOrderByIdAsc();   
}

alternative solution:

    @Repository
public class StudentServiceImpl implements StudentService {
    @Autowired
    private StudentDAO studentDao;

    @Override
    public List<Student> findAll() {
        return studentDao.findAll(orderByIdAsc());
    }
private Sort orderByIdAsc() {
    return new Sort(Sort.Direction.ASC, "id")
                .and(new Sort(Sort.Direction.ASC, "name"));
}
}

Spring Data Sorting: Sorting

Alternative

Using the example from Sarfraz above.

<div class="res">
    <a class="info_link" href="~/Resumes/Resumes1271354404687.docx">
        ~/Resumes/Resumes1271354404687.docx
    </a>
</div>

For href:

$(function(){
  $('.res').on('click', '.info_link', function(){
    alert($(this)[0].href);
  });
});

It would help if you provided the error you are seeing. Look at http://docs.oracle.com/javase/7/docs/api/java/lang/Math.html and you will see that max only returns the max between two numbers, so likely you code is not even compiling.

Solve all your compilation errors first.

Then your homework will consist of finding the max of three numbers by comparing the first two together, and comparing that max result with the third value. You should have enough to find your answer now.

var iframe = document.getElementById('iframeId');
var innerDoc = (iframe.contentDocument) ? iframe.contentDocument : iframe.contentWindow.document;

You could more simply write:

var iframe = document.getElementById('iframeId');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;

and the first valid inner doc will be returned.

Once you get the inner doc, you can just access its internals the same way as you would access any element on your current page. (innerDoc.getElementById...etc.)

IMPORTANT: Make sure that the iframe is on the same domain, otherwise you can't get access to its internals. That would be cross-site scripting.

Here's a reworking of your sample to get you started.

• your sample has a static event - it's more usual for an event to come from a class instance, but I've left it static below.

• the sample below also uses the more standard naming OnXxx for the method that raises the event.

• the sample below does not consider thread-safety, which may well be more of an issue if you insist on your event being static.

.

public enum MyEvents{ 
     Event1 
} 

public class MyEventArgs : EventArgs
{
    public MyEventArgs(MyEvents myEvents)
    {
        MyEvents = myEvents;
    }

    public MyEvents MyEvents { get; private set; }
}

public static class MyClass
{
     public static event EventHandler<MyEventArgs> EventTriggered; 

     public static void Trigger(MyEvents myEvents) 
     {
         OnMyEvent(new MyEventArgs(myEvents));
     }

     protected static void OnMyEvent(MyEventArgs e)
     {
         if (EventTriggered != null)
         {
             // Normally the first argument (sender) is "this" - but your example
             // uses a static event, so I'm passing null instead.
             // EventTriggered(this, e);
             EventTriggered(null, e);
         } 
     }
}

In my case, it was caused by an unseen trailing space at the end of the column name. Just check if you really use "y" or "y " instead.

As per the hibernate docs here,

Connection connection()

Deprecated. (scheduled for removal in 4.x). Replacement depends on need; for doing direct JDBC stuff use doWork(org.hibernate.jdbc.Work) ...

Use Hibernate Work API instead:

Session session = entityManager.unwrap(Session.class);
session.doWork(new Work() {

    @Override
    public void execute(Connection connection) throws SQLException {
        // do whatever you need to do with the connection
    }
});

Share this folder and use UNC path, by example: \pc\backups\mydb.bak

Then You can stop share.

Not very elegant, but it resolves all permissions problems (You need to give permissions to share as well, as mentioned above)

Trying to write a REST API from scratch is not a simple task. There are many issues to factor and you will need to write a lot of code to process requests and data coming from the caller, authentication, retrieval of data and sending back responses.

Your best bet is to use a framework that already has this functionality ready and tested for you.

Some suggestions are:

Phalcon - REST API building - Easy to use all in one framework with huge performance

Apigility - A one size fits all API handling framework by Zend Technologies

Laravel API Building Tutorial

and many more. Simple searches on Bitbucket/Github will give you a lot of resources to start with.

Width can be set to specific column as below: By percentages:

<asp:BoundField HeaderText="UserInfo"  DataField="UserInfo"  
SortExpression="UserInfo" ItemStyle-Width="100%"></asp:BoundField>

OR

By pixel:

<asp:BoundField HeaderText="UserInfo"  DataField="UserInfo"  
SortExpression="UserInfo" ItemStyle-Width="500px"></asp:BoundField>

Take note that you can get output by redirecting output to the file and then reading it

It was shown in documentation of std::system

You can receive exit code by calling WEXITSTATUS macro.

    int status = std::system("ls -l >test.txt"); // execute the UNIX command "ls -l >test.txt"
    std::cout << std::ifstream("test.txt").rdbuf();
    std::cout << "Exit code: " << WEXITSTATUS(status) << std::endl;

Install Xcode from the mac app store. Then use the command:

  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

the above will install homebrew and allow you to use brew in terminal

then just use command :

brew install boost

which would then install the boost libraries to <your macusername>/usr/local/Cellar/boost

May be by:-

    for(Row row : sheet) {          
        for(Cell cell : row) {              
            System.out.print(cell.getStringCellValue());

        }
    }       

For specific type of cell you can try:

switch (cell.getCellType()) {
case Cell.CELL_TYPE_STRING:
    cellValue = cell.getStringCellValue();
    break;

case Cell.CELL_TYPE_FORMULA:
    cellValue = cell.getCellFormula();
    break;

case Cell.CELL_TYPE_NUMERIC:
    if (DateUtil.isCellDateFormatted(cell)) {
        cellValue = cell.getDateCellValue().toString();
    } else {
        cellValue = Double.toString(cell.getNumericCellValue());
    }
    break;

case Cell.CELL_TYPE_BLANK:
    cellValue = "";
    break;

case Cell.CELL_TYPE_BOOLEAN:
    cellValue = Boolean.toString(cell.getBooleanCellValue());
    break;

}

def x(a):
    print(a)
    return a

def y(func_to_run, a):
    return func_to_run(a)

y(x, 1)

That I think would be a more proper sample. Now what I wonder is if there is a way to code the function to use within the argument submission to another function. I believe there is in C++, but in Python I am not sure.

There may be situations when df.reset_index() cannot be used (e.g., when you need the index, too). In this case, use index.get_level_values() to access index values directly:

df['Trial'] = df.index.get_level_values(0)
df['measurement'] = df.index.get_level_values(1)

This will assign index values to individual columns and keep the index.

See the docs for further info.

I would like share an example to understand the usage of stream().filter

Code Snippet: Sample program to identify even number.

import java.util.ArrayList;
import java.util.List;
import java.util.stream.Collectors;

public void fetchEvenNumber(){
        List<Integer> numberList = new ArrayList<>();
        numberList.add(10);
        numberList.add(11);
        numberList.add(12);
        numberList.add(13);
        numberList.add(14);
        numberList.add(15);

        List<Integer> evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());
        System.out.println(evenNumberListObj);
}

Output will be : [10, 12, 14]

List evenNumberListObj = numberList.stream().filter(i -> i%2 == 0).collect(Collectors.toList());

numberList: it is an ArrayList object contains list of numbers.

java.util.Collection.stream() : stream() will get the stream of collection, which will return the Stream of Integer.

filter: Returns a stream that match the given predicate. i.e based on given condition (i -> i%2 != 0) returns the matching stream.

collect: whatever the stream of Integer filter based in the filter condition, those integer will be put in a list.

You can also through the jquery function($.parseXML) to manipulate xml string

example javascript:

var xmlString = '<languages><language name="c"></language><language name="php"></language></languages>';
var xmlDoc = $.parseXML(xmlString);
$(xmlDoc).find('name').each(function(){
    console.log('name:'+$(this).attr('name'))
})

In an application level, here are something a developer can do:

From server side:

1. Check if load balancer(if you have),works correctly.

2. Turn slow TCP timeouts into 503 Fast Immediate response, if you load balancer work correctly, it should pick the working resource to serve, and it's better than hanging there with unexpected error massages.

Eg: If you are using node server, u can use toobusy from npm. Implementation something like:

var toobusy = require('toobusy');
app.use(function(req, res, next) {
  if (toobusy()) res.send(503, "I'm busy right now, sorry.");
  else next();
});

Why 503? Here are some good insights for overload: http://ferd.ca/queues-don-t-fix-overload.html

We can do some work in client side too:

1. Try to group calls in batch, reduce the traffic and total requests number b/w client and server.

2. Try to build a cache mid-layer to handle unnecessary duplicates requests.

Make sure you aren't using a Windows' directory separator character (backslash) in your path names in your .conf file, even if you are on Windows. Apache doesn't understand them but will still start up and then output a 403 Forbidden Message.

wrong:

<Directory "c:\websites\my-website\">

right:

<Directory "c:/websites/my-website/">

Office 365 and OneDrive offer an embed feature. You can then include via IFrame.

I found that setting the iframe height and width to 100% works best. That way on ipad or any device for that matter it fits the screen.

<body style="margin:0px;padding:0px;overflow:hidden">
    <iframe src="embed url" frameborder="0" style="overflow:hidden;overflow-x:hidden;overflow-y:hidden;height:100%;width:100%;position:absolute;top:0px;left:0px;right:0px;bottom:0px" height="100%" width="100%"></iframe>
</body>

$("#"+styleTarget).css('font-size', newFontSize);

Just apply scroll behaviour to all elements with this one-line code:

*{
scroll-behavior: smooth !important;
}

Generally when people are trying to animate display: none what they really want is:

1. Fade content in, and
2. Have the item not take up space in the document when hidden

Most popular answers use visibility, which can only achieve the first goal, but luckily it's just as easy to achieve both by using position.

Since position: absolute removes the element from typing document flow spacing, you can toggle between position: absolute and position: static (global default), combined with opacity. See the below example.

.content-page {_x000D_
  position:absolute;_x000D_
  opacity: 0;_x000D_
}_x000D_
_x000D_
.content-page.active {_x000D_
  position: static;_x000D_
  opacity: 1;_x000D_
  transition: opacity 1s linear;_x000D_
}

To properly load functions from ~/.config/fish/functions

You may set only ONE function inside file and name file the same as function name + add .fish extension.

This way changing file contents reload functions in opened terminals (note some delay may occur ~1-5s)

That way if you edit either by commandline

function name; function_content; end

then

funcsave name

you have user defined functions in console and custom made in the same order.

I wanted something similar - a function that parses a string that can be passed as a parameter or piped.

I came up with a solution as below (works as #!/bin/sh and as #!/bin/bash)

#!/bin/sh

set -eu

my_func() {
    local content=""
    
    # if the first param is an empty string or is not set
    if [ -z ${1+x} ]; then
 
        # read content from a pipe if passed or from a user input if not passed
        while read line; do content="${content}$line"; done < /dev/stdin

    # first param was set (it may be an empty string)
    else
        content="$1"
    fi

    echo "Content: '$content'"; 
}


printf "0. $(my_func "")\n"
printf "1. $(my_func "one")\n"
printf "2. $(echo "two" | my_func)\n"
printf "3. $(my_func)\n"
printf "End\n"

Outputs:

0. Content: ''
1. Content: 'one'
2. Content: 'two'
typed text
3. Content: 'typed text'
End

For the last case (3.) you need to type, hit enter and CTRL+D to end the input.

Initially, the default value is fullscreen for modalPresentationStyle, but in iOS 13 its changes to the UIModalPresentationStyle.automatic.

If you want to make the full-screen view controller you have to change the modalPresentationStyle to fullScreen.

Refer UIModalPresentationStyle apple documentation for more details and refer apple human interface guidelines for where should use which modality.

For me, there are some changes to make(ver. 2.20)

1. You set locale with moment.locale('de'), and you create a new object representing the date of now by moment() (note the parenthesis) and then format('LLL') it. The parenthesis is important.

So that means:

moment.locale('de');
var now = moment();
now.format('LLL');

2. Also, remember to use moment-with-locale.js. The file contains all locale info and has a larger file size. Download the locale folder is not enough. If necessary, change the name to be moment.js. Django just refuses to load moment-with-locale.js in my case.

EDIT: It turned out that renaming the file is not necessary. I just forgot to invoke it in the page so Django does not think loading it is necessary, so my fault.

Another way to find out if a program is installed is by using the which command. It will show the path of the program you're searching for. For example if when your searching for apache you can use the following command:

$ which apache2ctl
/usr/sbin/apache2ctl

And if you searching for PHP try this:

$ which php
/usr/bin/php

If the which command doesn't give any result it means the software is not installed (or is not in the current $PATH):

$ which php
$

As everyone here said, that's not possible directly.

The method I prefer and is rather clean, is to use an Object Mapper like AutoMapper.

It will do the task of copying properties from one instance to another (Not necessarily the same type) automatically.

1. The best getters / setters are smart.

Here's a javascript example from mozilla:

var o = { a:0 } // `o` is now a basic object

Object.defineProperty(o, "b", { 
    get: function () { 
        return this.a + 1; 
    } 
});

console.log(o.b) // Runs the getter, which yields a + 1 (which is 1)

I've used these A LOT because they are awesome. I would use it when getting fancy with my coding + animation. For example, make a setter that deals with an Number which displays that number on your webpage. When the setter is used it animates the old number to the new number using a tweener. If the initial number is 0 and you set it to 10 then you would see the numbers flip quickly from 0 to 10 over, let's say, half a second. Users love this stuff and it's fun to create.

2. Getters / setters in php

Example from sof

<?php
class MyClass {
  private $firstField;
  private $secondField;

  public function __get($property) {
    if (property_exists($this, $property)) {
      return $this->$property;
    }
  }

  public function __set($property, $value) {
    if (property_exists($this, $property)) {
      $this->$property = $value;
    }

    return $this;
  }
}
?>

make sure your database server is running if its not running then its not able to make connection and bydefault mysql running on 3306 so don't need mention port if same in case of port number is different then we need to mention port

Or:

SELECT SUM(foo), DATE(mydate) mydate FROM a_table GROUP BY mydate;

More efficient (I think.) Because you don't have to cast mydate twice per row.

From the MySQL prompt:

mysql> drop database <db_name>;

In Python 2.7 and above there is a class called Counter which can help you:

from collections import Counter
words_to_count = (word for word in word_list if word[:1].isupper())
c = Counter(words_to_count)
print c.most_common(3)

Result:

[('Jellicle', 6), ('Cats', 5), ('And', 2)]

I am quite new to programming so please try and do it in the most barebones fashion.

You could instead do this using a dictionary with the key being a word and the value being the count for that word. First iterate over the words adding them to the dictionary if they are not present, or else increasing the count for the word if it is present. Then to find the top three you can either use a simple O(n*log(n)) sorting algorithm and take the first three elements from the result, or you can use a O(n) algorithm that scans the list once remembering only the top three elements.

An important observation for beginners is that by using builtin classes that are designed for the purpose you can save yourself a lot of work and/or get better performance. It is good to be familiar with the standard library and the features it offers.

SOLUTION:

cd "Documents and Photos"

problem solved.

The reason I'm submitting this answer is you'll find that StackOverflow is being used by every day users (not just web devs, programmers or power users) and this was the number one result for a simple Windows user question on Google.

People are becoming more tech-savvy, but aren't necessarily familiar with command line in the cases above.

I wrote a .gitconfig [alias] for performing a "sparse checkout". Check it out (no pun intended):

On Windows run in cmd.exe

git config --global alias.sparse-checkout "!f(){ [ $# -eq 2 ] && L=${1##*/} L=${L%.git} || L=$2; mkdir -p \"$L/.git/info\" && cd \"$L\" && git init --template= && git remote add origin \"$1\" && git config core.sparseCheckout 1; [ $# -eq 2 ] && echo \"$2\" >> .git/info/sparse-checkout || { shift 2; for i; do echo $i >> .git/info/sparse-checkout; done }; git pull --depth 1 origin master;};f"

Otherwise:

git config --global alias.sparse-checkout '!f(){ [ $# -eq 2 ] && L=${1##*/} L=${L%.git} || L=$2; mkdir -p "$L/.git/info" && cd "$L" && git init --template= && git remote add origin "$1" && git config core.sparseCheckout 1; [ $# -eq 2 ] && echo "$2" >> .git/info/sparse-checkout || { shift 2; for i; do echo $i >> .git/info/sparse-checkout; done }; git pull --depth 1 origin master;};f'

Usage:

# Makes a directory ForStackExchange with Plug checked out
git sparse-checkout https://github.com/YenForYang/ForStackExchange Plug

# To do more than 1 directory, you have to specify the local directory:
git sparse-checkout https://github.com/YenForYang/ForStackExchange ForStackExchange Plug Folder

The git config commands are 'minified' for convenience and storage, but here is the alias expanded:

# Note the --template= is for disabling templates.
# Feel free to remove it if you don't have issues with them (like I did)
# `mkdir` makes the .git/info directory ahead of time, as I've found it missing sometimes for some reason
f(){
    [ "$#" -eq 2 ] && L="${1##*/}" L=${L%.git} || L=$2;
    mkdir -p "$L/.git/info"
        && cd "$L"
        && git init --template=
        && git remote add origin "$1"
        && git config core.sparseCheckout 1;
    [ "$#" -eq 2 ]
        && echo "$2" >> .git/info/sparse-checkout
        || {
            shift 2;
            for i; do
                echo $i >> .git/info/sparse-checkout;
            done
        };
    git pull --depth 1 origin master;
};
f

Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)

The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B cmd

%SendKeys% "echo off{ENTER}"

set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"

set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"

set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"

%SendKeys% "exit{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));

For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx

For example:

LEFT ARROW    {LEFT}
RIGHT ARROW   {RIGHT}

For a further explanation of this solution, see: GnuWin32 openssl s_client conn to WebSphere MQ server not closing at EOF, hangs

For JSON data, it's much easier to POST it as "application/json" content-type. If you use GET, you have to URL-encode the JSON in a parameter and it's kind of messy. Also, there is no size limit when you do POST. GET's size if very limited (4K at most).

Just to make searching easier, as mentioned in comments, this is not possible since 3.1 https://stackoverflow.com/a/19856367/6505257

I think it's best if you use methods with generic arguments, like the following :

public static void SerializeToXml<T>(T obj, string fileName)
{
    using (var fileStream = new FileStream(fileName, FileMode.Create))
    { 
        var ser = new XmlSerializer(typeof(T)); 
        ser.Serialize(fileStream, obj);
    }
}

public static T DeserializeFromXml<T>(string xml)
{
    T result;
    var ser = new XmlSerializer(typeof(T));
    using (var tr = new StringReader(xml))
    {
        result = (T)ser.Deserialize(tr);
    }
    return result;
}

As of Java 8, you can simply use java.util.Base64 to try and decode the string:

String someString = "...";
Base64.Decoder decoder = Base64.getDecoder();

try {
    decoder.decode(someString);
} catch(IllegalArgumentException iae) {
    // That string wasn't valid.
}

Don't use wsgiref for production. Use Apache and mod_wsgi, or something else.

We continue to see these connection resets, sometimes frequently, with wsgiref (the backend used by the werkzeug test server, and possibly others like the Django test server). Our solution was to log the error, retry the call in a loop, and give up after ten failures. httplib2 tries twice, but we needed a few more. They seem to come in bunches as well - adding a 1 second sleep might clear the issue.

We've never seen a connection reset when running through Apache and mod_wsgi. I don't know what they do differently, (maybe they just mask them), but they don't appear.

When we asked the local dev community for help, someone confirmed that they see a lot of connection resets with wsgiref that go away on the production server. There's a bug there, but it is going to be hard to find it.

If using the above solution of two <VirtualHost *:80> blocks with different ServerNames...

<VirtualHost *:80>
    ServerName example.com
    Redirect permanent / http://www.example.com/
</VirtualHost>
<VirtualHost *:80>
    ServerName www.example.com
</VirtualHost>

... then you must set NameVirtualHost On as well.

If you don't do this, Apache doesn't allow itself to use the different ServerNames to distinguish the blocks, so you get this error message:

[warn] _default_ VirtualHost overlap on port 80, the first has precedence

...and either no redirection happens, or you have an infinite redirection loop, depending on which block you put first.

Unity is a library like many others that allows you to get an instance of a requested type without having to create it yourself. So given.

public interface ICalculator
{
    void Add(int a, int b);
}

public class Calculator : ICalculator
{
    public void Add(int a, int b)
    {
        return a + b;
    }
}

You would use a library like Unity to register Calculator to be returned when the type ICalculator is requested aka IoC (Inversion of Control) (this example is theoretical, not technically correct).

IoCLlibrary.Register<ICalculator>.Return<Calculator>();

So now when you want an instance of an ICalculator you just...

Calculator calc = IoCLibrary.Resolve<ICalculator>();

IoC libraries can usually be configured to either hold a singleton or create a new instance every time you resolve a type.

Now let's say you have a class that relies on an ICalculator to be present you could have..

public class BankingSystem
{
    public BankingSystem(ICalculator calc)
    {
        _calc = calc;
    }

    private ICalculator _calc;
}

And you can setup the library to inject a object into the constructor when it's created.

So DI or Dependency Injection means to inject any object another might require.

Here is the answer if you want to put image with fixed percentage of width, but not fixed pixel of width.

And this will be useful when dealing with different size of screen.

The tricks are

1. Using padding-top to set the height from width.
2. Using position: absolute to put image in the padding space.
3. Using max-height and max-width to make sure the image will not over the parent element.
4. using display:block and margin: auto to center the image.

I've also comment most of the tricks inside the fiddle.

I also find some other ways to make this happen. There will be no real image in html, so I personly perfer the top answer when I need "img" element in html.

simple css by using background http://jsfiddle.net/4660s79h/2/

background-image with word on top http://jsfiddle.net/4660s79h/1/

the concept to use position absolute is from here http://www.w3schools.com/howto/howto_css_aspect_ratio.asp

string path = AppDomain.CurrentDomain.GetData("DataDirectory").ToString();

This is probably a more "correct" way of getting it.

For most of my select options, I start off with an option that simply says 'Please Select' or something similar and that option is always disabled. Then whenever you want to clear your select/option's you can do just do something like this.

Example

<select id="mySelectOption">
   <option value="" selected disabled>Please select</option>
</select>

Answer

$('#mySelectOption').val('Please Select');

According to this post this error message means:

Heap size is larger than your computer's physical memory.

Edit: Heap is not the only memory that is reserved, I suppose. At least there are other JVM settings like PermGenSpace that ask for the memory. With heap size 128M and a PermGenSpace of 64M you already fill the space available.

Why not downsize other memory settings to free up space for the heap?

As I wrote in my comment, the solution to your problem is to write the following:

Set hyperLinkText = hprlink.Range

Set is needed because TextRange is a class, so hyperLinkText is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.

@ECHO off & SETLOCAL EnableDelayedExpansion

SET "_dir=" REM Must finish with '\'
SET "_ext=jpg"
SET "_toEdit=Vacation2010"
SET "_with=December"
FOR %%f IN ("%_dir%*.%_ext%") DO (
    CALL :modifyString "%_toEdit%" "%_with%" "%%~Nf" fileName 
    RENAME "%%f" "!fileName!%%~Xf"
)
GOTO end

:modifyString what with in toReturn
    SET "__in=%~3"
    SET "__in=!__in:%~1=%~2!"
    IF NOT "%~4" == "" (
        SET %~4=%__in%
    ) ELSE (
        ECHO %__in%
    )
    EXIT /B

:end

This script allows you to change the name of all the files that contain Vacation2010 with the same name, but with December instead of Vacation2010.

If you copy and paste the code, you have to save the .bat in the same folder of the photos. If you want to save the script in another directory [E.G. you have a favorite folder for the utilities] you have to change the value of _dir with the path of the photos.

If you have to do the same work for other photos [or others files changig _ext] you have to change the value of _toEdit with the string you want to change [or erase] and the value of _with with the string you want to put instead of _toEdit [SET "_with=" if you simply want to erase the string specified in _toEdit].

make sure ,use this 404 route wrote on the bottom of the code.

syntax will be like

{
    path: 'page-not-found', 
    component: PagenotfoundComponent
},
{
    path: '**',

},

In addition to Trufa's comment, Unicode explicitly isn't UTF-16. When they were first looking into Unicode, it was speculated that a 16-bit integer might be enough to store any code, but in practice that turned out not to be the case. However, UTF-16 is another valid encoding of Unicode - alongside the 8-bit and 32-bit variants - and I believe is the encoding that Microsoft use in memory at runtime on the NT-derived operating systems.

Looking for a similar solution I just came across this brand new tutorial, which lets you bridge a Swift gradient background (https://github.com/soffes/GradientView) library while walking through every step to get a working React component.

It is a step-by-step tutorial, allowing you to build your own component by bridging the swift and objective-c component into a usable React Native component, which overrides the standard View component and allows you to define a gradient like the following:

 <LinearGradient 
   style={styles.gradient} 
   locations={[0, 1.0]} 
   colors={['#5ED2A0', '#339CB1']}
 />

You can find the tutorial here: http://browniefed.com/blog/2015/11/28/react-native-how-to-bridge-a-swift-view/

Here is the simplest solution that worked for me.

The ActionBarDrawerToggle has two types constructors. One of them take toolbar as a parameter. Use that (second one below) to get the animated hamburger.

ActionBarDrawerToggle(this, mDrawerLayout, R.string.content_desc_drawer_open, 
R.string.content_desc_drawer_close);

ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.content_desc_drawer_open, 
R.string.content_desc_drawer_close);`  //use this constructor

If you have perl installed, then perl -i -n -e"print unless m{(ERROR|REFERENCE)}" should do the trick.

If you are (like me) using git bash on windows, you just need to put

winpty

before your 'docker line' :

winpty docker exec -it some_cassandra bash

Some time ago, I used this.

Perhaps you could try:

+function(){
    var my_var = function get_this_name(){
        alert("I " + this.init());
    };
    my_var.prototype.init = function(){
        return my_var.name;
    }
    new my_var();
}();

Pop an Alert: "I get_this_name".

Although post is old I had the same problem with mingw32 vers 4.8.1 on 2015/02/13. Compiling using Eclipse CDT failed with this message. Trying from command line with -v option also failed. I was also missing the cc1plus executable.

The cause: I downloaded the command line and graphical installer from the mingw32 site. I used this to do my initial install of mingw32. Using the GUI I selected the base tools, selecting both the c and c++ compilers.

This installer did an incomplete install of the 32 bit c++ compiler. I had the g++ and cpp files but not the cc1plus executable. Trying to do an 'update' failed because the installer assumed I had everything installed.

To fix I found these sites: http://mingw-w64.sourceforge.net/ http://sourceforge.net/projects/mingw-w64/ I downloaded and ran this 'online install'. Sure enough this one contained the missing files. I modified my PATH variable and pointed to the 'bin' folder containing the g++ executable. Rebooted. Installed 64 bit Eclipse. Opened Eclipse and the 'Hello World' c++ program compiled, executed, and debugged properly.

Note: the 64bit installer seems to default to UNIX settings. Why can't an installer determine the OS??? Make sure to change them.

I spent an entire evening dealing with this. Hope this helps someone.

You cannot iterate over them directly, but you can find all the keys and then just sort them.

var a = new Array();
a['b'] = 1;
a['z'] = 1;
a['a'] = 1;    

function keys(obj)
{
    var keys = [];

    for(var key in obj)
    {
        if(obj.hasOwnProperty(key))
        {
            keys.push(key);
        }
    }

    return keys;
}

keys(a).sort(); // ["a", "b", "z"]

However there is no need to make the variable 'a' an array. You are really just using it as an object and should create it like this:

var a = {};
a["key"] = "value";

To offer an update on the situation on Q2 of 2017.

A new CSS3 display property is available in Firefox 53, Chrome 58 and Opera 45.

.clearfix {
   display: flow-root;
}

Check the availability for any browser here: http://caniuse.com/#feat=flow-root

The element (with a display property set to flow-root) generates a block container box, and lays out its contents using flow layout. It always establishes a new block formatting context for its contents.

Meaning that if you use a parent div containing one or several floating children, this property is going to ensure the parent encloses all of its children. Without any need for a clearfix hack. On any children, nor even a last dummy element (if you were using the clearfix variant with :before on the last children).

.container {_x000D_
  display: flow-root;_x000D_

clean is its own build lifecycle phase (which can be thought of as an action or task) in Maven. mvn clean install tells Maven to do the clean phase in each module before running the install phase for each module.

What this does is clear any compiled files you have, making sure that you're really compiling each module from scratch.

I too have faced similar issue when i started to work on Hibernate. All in all i can say is in the createQuery one needs to pass the name of the entity class not the table name to which the entity is mapped to.

If you don't mind using two Lists, then this is probably the easiest way to do it, but probably not the most efficient or unpredictable one:

List<int> xList = new List<int>() { 1, 2, 3, 4, 5 };
List<int> deck = new List<int>();

foreach (int xInt in xList)
    deck.Insert(random.Next(0, deck.Count + 1), xInt);

This is my working code for express 4.0.

express 4.0 is very different from 3.0 and others.

4.0 you have /bin/www file, which you are going to add https here.

"npm start" is standard way you start express 4.0 server.

readFileSync() function should use __dirname get current directory

while require() use ./ refer to current directory.

First you put private.key and public.cert file under /bin folder, It is same folder as WWW file.

no such directory found error:

  key: fs.readFileSync('../private.key'),

  cert: fs.readFileSync('../public.cert')

error, no such directory found

  key: fs.readFileSync('./private.key'),

  cert: fs.readFileSync('./public.cert')

Working code should be

key: fs.readFileSync(__dirname + '/private.key', 'utf8'),

cert: fs.readFileSync(__dirname + '/public.cert', 'utf8')

Complete https code is:

const https = require('https');
const fs = require('fs');

// readFileSync function must use __dirname get current directory
// require use ./ refer to current directory.

const options = {
   key: fs.readFileSync(__dirname + '/private.key', 'utf8'),
  cert: fs.readFileSync(__dirname + '/public.cert', 'utf8')
};


 // Create HTTPs server.

 var server = https.createServer(options, app);

The second approach is clearly wrong if you want to cast. It instantiate a new ArrayList.

However the first approach should work just fine, if and only if getAllTasks return an ArrayList.

It is really needed for you to have an ArrayList ? isn't the List interface enough ? What you are doing can leads to Runtime Exception if the type isn't correct.

If getAllTasks() return an ArrayList you should change the return type in the class definition and then you won't need a cast and if it's returning something else, you can't cast to ArrayList.

You can look at the javadoc of the Pattern class: http://docs.oracle.com/javase/8/docs/api/java/util/regex/Pattern.html

You need to escape any char listed there if you want the regular char and not the special meaning.

As a maybe simpler solution, you can put the template between \Q and \E - everything between them is considered as escaped.

With kotlin and Gson we can do it more easily:

1. First, add Gson dependency:

implementation "com.squareup.retrofit2:converter-gson:2.3.0"

2. Create a separate kotlin file, add the following methods

import com.google.gson.Gson
import com.google.gson.reflect.TypeToken

fun <T> Gson.convertToJsonString(t: T): String {
    return toJson(t).toString()
}

fun <T> Gson.convertToModel(jsonString: String, cls: Class<T>): T? {
    return try {
        fromJson(jsonString, cls)
    } catch (e: Exception) {
        null
    }
}

inline fun <reified T> Gson.fromJson(json: String) = this.fromJson<T>(json, object: TypeToken<T>() {}.type)

Note: Do not add declare class, just add these methods, everything will work fine.

3. Now to call:

create a reference of gson:

val gson=Gson()

To convert array to json string, call:

val jsonString=gson.convertToJsonString(arrayList)

To get array from json string, call:

val arrayList=gson.fromJson<ArrayList<YourModelClassName>>(jsonString)

To convert a model to json string, call:

val jsonString=gson.convertToJsonString(model)

To convert json string to model, call:

val model=gson.convertToModel(jsonString, YourModelClassName::class.java)

If you are certain that you have a JDK installed (and not a JRE), you can specify the location of the JDK on the commandline when starting the installer (as mentioned in the error message you get).

Try rmtree() in shutil from the Python standard library

as posted by @randymohan, with using statements instead

public static void WriteLog(string strLog)
{
    string logFilePath = @"C:\Logs\Log-" + System.DateTime.Today.ToString("MM-dd-yyyy") + "." + "txt";
    FileInfo logFileInfo = new FileInfo(logFilePath);
    DirectoryInfo logDirInfo = new DirectoryInfo(logFileInfo.DirectoryName);
    if (!logDirInfo.Exists) logDirInfo.Create();
    using (FileStream fileStream = new FileStream(logFilePath, FileMode.Append))
    {
        using (StreamWriter log = new StreamWriter(fileStream))
        {
            log.WriteLine(strLog);
        }
    }
}

Why not just use rm -rf /some/dir? That will remove the directory if it's present, otherwise do nothing. Unlike rm -r /some/dir this flavor of the command won't crash if the folder doesn't exist.

You can be specific by testing for not valid characters. This will return true for anything not alphanumeric and space:

var specials = /[^A-Za-z 0-9]/g;
return specials.test(input.val());

Don't use os.walk.

Example:

import os

root = "C:\\"
for item in os.listdir(root):
    if os.path.isfile(os.path.join(root, item)):
        print item

If you're putting a <meta> tag in your css files, you're doing something wrong. The <meta> tag belongs in your html files, and tells the browser how the html is encoded, it doesn't say anything about the css, which is a separate file. You could conceivably have completely different encodings for your html and css, although I can't imagine this would be a good idea.

Generally speaking, these days with any modern compiler worrying about inlining anything is pretty much a waste of time. The compiler should actually optimize all of these considerations for you through its own analysis of the code and your specification of the optimization flags passed to the compiler. If you care about speed, tell the compiler to optimize for speed. If you care about space, tell the compiler to optimize for space. As another answer alluded to, a decent compiler will even inline automatically if it really makes sense.

Also, as others have stated, using inline does not guarantee inline of anything. If you want to guarantee it, you will have to define a macro instead of an inline function to do it.

When to inline and/or define a macro to force inclusion? - Only when you have a demonstrated and necessary proven increase in speed for a critical section of code that is known to have an affect on the overall performance of the application.

var result = from entry in table
                     where entry.something == null
                     select entry;

The above query works as intended. It correctly generates IS NULL. My production code however was

var value = null;
var result = from entry in table
                         where entry.something == value
                         select entry;

and the generated SQL was something = @p; @p = NULL. It seems that EF correctly translates the constant expression but if a variable is involved it treats it just like a normal comparison. Makes sense actually.

NON BREAKING SPACE ISSUE

In some browsers

(MSIE "as usually" ;-))

replacing space in string ignores the non-breaking space (the 160 char code).

One should always replace like this:

myString.replace(/[ \u00A0]/, myReplaceString)

Very nice detailed explanation:

http://www.adamkoch.com/2009/07/25/white-space-and-character-160/

You can further modify the hput()/hget() interface so that you have named hashes as follows:

hput() {
    eval "$1""$2"='$3'
}

hget() {
    eval echo '${'"$1$2"'#hash}'
}

and then

hput capitals France Paris
hput capitals Netherlands Amsterdam
hput capitals Spain Madrid
echo `hget capitals France` and `hget capitals Netherlands` and `hget capitals Spain`

This lets you define other maps that don't conflict (e.g., 'rcapitals' which does country lookup by capital city). But, either way, I think you'll find that this is all pretty terrible, performance-wise.

If you really want fast hash lookup, there's a terrible, terrible hack that actually works really well. It is this: write your key/values out to a temporary file, one-per line, then use 'grep "^$key"' to get them out, using pipes with cut or awk or sed or whatever to retrieve the values.

Like I said, it sounds terrible, and it sounds like it ought to be slow and do all sorts of unnecessary IO, but in practice it is very fast (disk cache is awesome, ain't it?), even for very large hash tables. You have to enforce key uniqueness yourself, etc. Even if you only have a few hundred entries, the output file/grep combo is going to be quite a bit faster - in my experience several times faster. It also eats less memory.

Here's one way to do it:

hinit() {
    rm -f /tmp/hashmap.$1
}

hput() {
    echo "$2 $3" >> /tmp/hashmap.$1
}

hget() {
    grep "^$2 " /tmp/hashmap.$1 | awk '{ print $2 };'
}

hinit capitals
hput capitals France Paris
hput capitals Netherlands Amsterdam
hput capitals Spain Madrid

echo `hget capitals France` and `hget capitals Netherlands` and `hget capitals Spain`

Therefore, before starting '$ sqlplus' on OS, run the followings:

• On Windows

  set NLS_LANG=AMERICAN_AMERICA.UTF8

• On Unix (Solaris and Linux, centos etc)

  export NLS_LANG=AMERICAN_AMERICA.UTF8

It would also be advisable to set env variable in your '.bash_profile' [on start up script]

This is the place where other ORACLE env variables (ORACLE_SID, ORACLE_HOME) are usually set.

just fyi - SQL Developer is good at displaying/handling non-English UTF8 characters.

If you don't want to make your spring a web application then just add @EnableAsync or @EnableScheduling to your Starter

@EnableAsync
@SpringBootApplication
public class App {
    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

}

In my opinion using a BroadcastReceiver is a cleaner way to cancel a Notification:

In AndroidManifest.xml:

<receiver 
    android:name=.NotificationCancelReceiver" >
    <intent-filter android:priority="999" >
         <action android:name="com.example.cancel" />
    </intent-filter>
</receiver>

In java File:

Intent cancel = new Intent("com.example.cancel");
PendingIntent cancelP = PendingIntent.getBroadcast(context, 0, cancel, PendingIntent.FLAG_CANCEL_CURRENT);

NotificationCompat.Action actions[] = new NotificationCompat.Action[1];

NotificationCancelReceiver

public class NotificationCancelReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        //Cancel your ongoing Notification
    };
}

I'm running Qt 5.5 under Windows and the default constructor of QDir appears to pick up the current working directory, not the application directory.

I'm not sure if the getenv PWD will work cross-platform and I think it is set to the current working directory when the shell launched the application and doesn't include any working directory changes done by the app itself (which might be why the OP is seeing this behavior).

So I thought I'd add some other ways that should give you the current working directory (not the application's binary location):

// using where a relative filename will end up
QFileInfo fi("temp");
cout << fi.absolutePath() << endl;

// explicitly using the relative name of the current working directory
QDir dir(".");
cout << dir.absolutePath() << endl;

revalidate is called on a container once new components are added or old ones removed. this call is an instruction to tell the layout manager to reset based on the new component list. revalidate will trigger a call to repaint what the component thinks are 'dirty regions.' Obviously not all of the regions on your JPanel are considered dirty by the RepaintManager.

repaint is used to tell a component to repaint itself. It is often the case that you need to call this in order to cleanup conditions such as yours.

An easy way to parse (and validate) URL's is the urlparse (py2, py3) module.

A regex is too much work.

There's no "validate" method because almost anything is a valid URL. There are some punctuation rules for splitting it up. Absent any punctuation, you still have a valid URL.

Check the RFC carefully and see if you can construct an "invalid" URL. The rules are very flexible.

For example ::::: is a valid URL. The path is ":::::". A pretty stupid filename, but a valid filename.

Also, ///// is a valid URL. The netloc ("hostname") is "". The path is "///". Again, stupid. Also valid. This URL normalizes to "///" which is the equivalent.

Something like "bad://///worse/////" is perfectly valid. Dumb but valid.

Bottom Line. Parse it, and look at the pieces to see if they're displeasing in some way.

Do you want the scheme to always be "http"? Do you want the netloc to always be "www.somename.somedomain"? Do you want the path to look unix-like? Or windows-like? Do you want to remove the query string? Or preserve it?

These are not RFC-specified validations. These are validations unique to your application.

I had the same problem as the original poster but the quoted answer did not solve the problem for me. The query still ran really slow from a stored procedure.

I found another answer here "Parameter Sniffing", Thanks Omnibuzz. Boils down to using "local Variables" in your stored procedure queries, but read the original for more understanding, it's a great write up. e.g.

Slow way:

CREATE PROCEDURE GetOrderForCustomers(@CustID varchar(20))
AS
BEGIN
    SELECT * 
    FROM orders
    WHERE customerid = @CustID
END

Fast way:

CREATE PROCEDURE GetOrderForCustomersWithoutPS(@CustID varchar(20))
AS
BEGIN
    DECLARE @LocCustID varchar(20)
    SET @LocCustID = @CustID

    SELECT * 
    FROM orders
    WHERE customerid = @LocCustID
END

Hope this helps somebody else, doing this reduced my execution time from 5+ minutes to about 6-7 seconds.

ScheduledThreadPoolExecutor has this ability, but it's quite heavyweight.

Timer also has this ability but opens several thread even if used only once.

Here's a simple implementation with a test (signature close to Android's Handler.postDelayed()):

public class JavaUtil {
    public static void postDelayed(final Runnable runnable, final long delayMillis) {
        final long requested = System.currentTimeMillis();
        new Thread(new Runnable() {
            @Override
            public void run() {
                // The while is just to ignore interruption.
                while (true) {
                    try {
                        long leftToSleep = requested + delayMillis - System.currentTimeMillis();
                        if (leftToSleep > 0) {
                            Thread.sleep(leftToSleep);
                        }
                        break;
                    } catch (InterruptedException ignored) {
                    }
                }
                runnable.run();
            }
        }).start();
    }
}

Test:

@Test
public void testRunsOnlyOnce() throws InterruptedException {
    long delay = 100;
    int num = 0;
    final AtomicInteger numAtomic = new AtomicInteger(num);
    JavaUtil.postDelayed(new Runnable() {
        @Override
        public void run() {
            numAtomic.incrementAndGet();
        }
    }, delay);
    Assert.assertEquals(num, numAtomic.get());
    Thread.sleep(delay + 10);
    Assert.assertEquals(num + 1, numAtomic.get());
    Thread.sleep(delay * 2);
    Assert.assertEquals(num + 1, numAtomic.get());
}

I would really like to see your TABLE's styling. E.g. "border-collapse"

Just a guess, but it might affect how 'hidden' rows are being rendered.

Environments created with the --prefix or -p flag must be removed with the -p flag (not -n).

For example: conda remove -p </filepath/myenvironment> --all, in which </filepath/myenvironment> is substituted with a complete or relative path to the environment.

Use the return keyword.

return; //exit this event

Basically, it depends on the TableModel that you are using for your JTable. If you are using the DefaultTableModel then you can do it in two ways:

DefaultTableModel dm = (DefaultTableModel)table.getModel();
dm.getDataVector().removeAllElements();
dm.fireTableDataChanged(); // notifies the JTable that the model has changed

or

DefaultTableModel dm = (DefaultTableModel)table.getModel();
while(dm.getRowCount() > 0)
{
    dm.removeRow(0);
}

See the JavaDoc of DefaultTableModel for more details

Essentially console.log("Put a message here.") if the browser has a supporting console.

Another typical debugging method is using alerts, alert("Put a message here.")

RE: Update II

This seems to make sense, you are trying to automate QUnit tests, from what I have read on QUnit this is an in-browser unit testing suite/library. QUnit expects to run in a browser and therefore expects the browser to recognize all of the JavaScript functions you are calling.

Based on your Maven configuration it appears you are using Rhino to execute your Javascript at the command line/terminal. This is not going to work for testing browser specifics, you would likely need to look into Selenium for this. If you do not care about testing your JavaScript in a browser but are only testing JavaScript at a command line level (for reason I would not be familiar with) it appears that Rhino recognizes a print() method for evaluating expressions and printing them out. Checkout this documentation.

These links might be of interest to you.

Simple flatten util i've written

const flatten = (arr, result = []) => {
    if (!Array.isArray(arr)){
        return [...result, arr];
    }
     arr.forEach((a) => {
         result = flatten(a, result)
    })

    return result
}

console.log(flatten([1,[2,3], [4,[5,6,[7,8]]]])) // [ 1, 2, 3, 4, 5, 6, 7, 8 ]

By comparing the solution below with the one that uses cumsum of numpy, This one takes almost half the time. This is because it does not need to go through the entire array to do the cumsum and then do all the subtraction. Moreover, the cumsum can be "dangerous" if the array is huge and the number are huge (possible overflow). Of course, also here the danger exists but at least are summed together only the essential numbers.

def moving_average(array_numbers, n):
    if n > len(array_numbers):
      return []
    temp_sum = sum(array_numbers[:n])
    averages = [temp_sum / float(n)]
    for first_index, item in enumerate(array_numbers[n:]):
        temp_sum += item - array_numbers[first_index]
        averages.append(temp_sum / float(n))
    return averages

To create an option that needs no value, set the action ^[docs] of it to 'store_const', 'store_true' or 'store_false'.

Example:

parser.add_argument('-s', '--simulate', action='store_true')

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

If you need to parse quotes escaped with another quote, example:

"some ""value"" that is on xlsx file",123

You can use

function parse(text) {
  const csvExp = /(?!\s*$)\s*(?:'([^'\\]*(?:\\[\S\s][^'\\]*)*)'|"([^"\\]*(?:\\[\S\s][^"\\]*)*)"|"([^""]*(?:"[\S\s][^""]*)*)"|([^,'"\s\\]*(?:\s+[^,'"\s\\]+)*))\s*(?:,|$)/g;

  const values = [];

  text.replace(csvExp, (m0, m1, m2, m3, m4) => {
    if (m1 !== undefined) {
      values.push(m1.replace(/\\'/g, "'"));
    }
    else if (m2 !== undefined) {
      values.push(m2.replace(/\\"/g, '"'));
    }
    else if (m3 !== undefined) {
      values.push(m3.replace(/""/g, '"'));
    }
    else if (m4 !== undefined) {
      values.push(m4);
    }
    return '';
  });

  if (/,\s*$/.test(text)) {
    values.push('');
  }

  return values;
}

If you are not root user then, use following commands:

There are two ways to do it -

1.

sudo vi path_to_file/file_name

Press Esc and then type below respectively

:wq //save and exit
:q! //exit without saving

2. sudo nano path_to_file/file_name

When using nano: after you finish editing press ctrl+x then it will ask save Y/N.
If you want to save press Y, if not press N. And press enter to exit the editor.

Since 2.3 version of Gson library the JsonArray class have a 'set' method.

Here's an simple example:

JsonArray array = new JsonArray();
array.add(new JsonPrimitive("Red"));
array.add(new JsonPrimitive("Green"));
array.add(new JsonPrimitive("Blue"));

array.remove(2);
array.set(0, new JsonPrimitive("Yelow"));

Send SMS/Text Messages from Command Line with VBScript!

If VBA meets the rules for VB Script then it can be called from command line by simply placing it into a text file - in this case there's no need to specifically open Outlook.

I had a need to send automated text messages to myself from the command line, so I used the code below, which is just a compressed version of @Geoff's answer above.

Most mobile phone carriers worldwide provide an email address "version" of your mobile phone number. For example in Canada with Rogers or Chatr Wireless, an email sent to <YourPhoneNumber> @pcs.rogers.com will be immediately delivered to your Rogers/Chatr phone as a text message.

* ^{You may need to "authorize" the first message on your phone, and some carriers may charge an additional fee for theses message although as far as I know, all Canadian carriers provide this little-known service for free. Check your carrier's website for details.}

There are further instructions and various compiled lists of worldwide carrier's Email-to-Text addresses available online such as this and this and this.

Code & Instructions

1. Copy the code below and paste into a new file in your favorite text editor.
2. Save the file with any name with a .VBS extension, such as TextMyself.vbs.

That's all!
Just double-click the file to send a test message, or else run it from a batch file using START.

Sub SendMessage()
    Const EmailToSMSAddy = "[email protected]"
    Dim objOutlookRecip
    With CreateObject("Outlook.Application").CreateItem(0)
        Set objOutlookRecip = .Recipients.Add(EmailToSMSAddy)
        objOutlookRecip.Type = 1
        .Subject = "The computer needs your attention!"
        .Body = "Go see why Windows Command Line is texting you!"
        .Save
        .Send
    End With
End Sub

Example Batch File Usage:

START x:\mypath\TextMyself.vbs

Of course there are endless possible ways this could be adapted and customized to suit various practical or creative needs.

There are numerous methods of accomplishing this, which I'll detail with a few examples below.

Pure CSS (using a grayscale and colored images)

This approach requires two copies of an image: one in grayscale and the other in full color. Using the CSS :hover psuedoselector, you can update the background of your element to toggle between the two:

#yourimage { 
    background: url(../grayscale-image.png);
}
#yourImage:hover { 
    background: url(../color-image.png};
}

#google {_x000D_
  background: url('http://www.google.com/logos/keystroke10-hp.png');_x000D_
  height: 95px;_x000D_
  width: 275px;_x000D_
  display: block;_x000D_
  /* Optional for a gradual animation effect */_x000D_
  transition: 0.5s;_x000D_
}_x000D_
_x000D_
#google:hover {_x000D_
  background: url('https://graphics217b.files.wordpress.com/2011/02/logo1w.png');_x000D_
}

<a id='google' href='http://www.google.com'></a>

This could also be accomplished by using a Javascript-based hover effect such as jQuery's hover() function in the same manner.

Consider a Third-Party Library

The desaturate library is a common library that allows you to easily switch between a grayscale version and full-colored version of a given element or image.

I agree with all the above unless:

sys.argv[1] was something like Chicken\d{2}-\d{2}An\s*important\s*anchor

sys.argv[1] = "Chicken\d{2}-\d{2}An\s*important\s*anchor"

you would not want to use re.escape, because in that case you would like it to behave like a regex

TEXTO = sys.argv[1]

if re.search(r"\b(?<=\w)" + TEXTO + "\b(?!\w)", subject, re.IGNORECASE):
    # Successful match
else:
    # Match attempt failed

The most readable way is

x = 10 if a > b else 11

but you can use and and or, too:

x = a > b and 10 or 11

The "Zen of Python" says that "readability counts", though, so go for the first way.

Also, the and-or trick will fail if you put a variable instead of 10 and it evaluates to False.

However, if more than the assignment depends on this condition, it will be more readable to write it as you have:

if A[i] > B[j]:
  x = A[i]
  i += 1
else:
  x = A[j]
  j += 1

unless you put i and j in a container. But if you show us why you need it, it may well turn out that you don't.

I have a solution that worked on my Windows 7 machine.

I believe PyCharm's terminal is a result of it running cmd.exe, which will load the Windows PATH variable, and use the version of Python that it finds first within that PATH. To edit this variable, right click My Computer --> Properties --> Advanced System Settings --> Advanced tab --> Environment Variables... button. Within the System variables section, select and edit the PATH variable.

Here is the relevant part of my PATH before editing:

C:\Python27\;
C:\Python27\Lib\site-packages\pip\;
C:\Python27\Scripts;
C:\Python27\Lib\site-packages\django\bin;

...and after editing PATH (only 3 lines now):

C:[project_path]\virtualenv-Py2.7_Dj1.7\Lib\site-packages\pip;
C:[project_path]\virtualenvs\virtualenv-Py2.7_Dj1.7\Scripts;
C:[project_path]\virtualenvs\virtualenv-Py2.7_Dj1.7\Lib\site-packages\django\bin;

To test this, open a new windows terminal (Start --> type in cmd and hit Enter) and see if it's using your virtual environment. If that works, restart PyCharm and then test it out in PyCharm's terminal.

Laravel is slow, because in most cases, using PHP for web pages is slow.

With Laravel, the entire framework is rebuilt on every invocation - that is why all pages point to index.php. Since the entire framework is PHP scripts, they all need to go through the PHP interpreter - each time. The larger the framework, the longer this takes.

Contrast this with a "server environment" (e.g. tomcat) where the server runs the initialization code once, and eventually all pages will be in native code (after JIT).

As a reference example, using the same hardware, OS, etc. a simple 'hello world' using JSP on this hardware is 3000 rps, the same hello world on laravel is 51 rps.

The easiest way to test framework overhead, and the resulting maximum RPS per core, is to use Apache AB and a concurrency value of 1, with a simple 'hello world' that is dynamic (to avoid static page caching).

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

gcc test.c -o test -lm

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

Despite 90% of all the information I found (while trying to find a solution to this error) telling me to add the HttpGet and HttpPost to the configuration, that did not work for me... and didn't make sense to me anyway.

My application is running on lots of servers (30+) and I've never had to add this configuration for any of them. Either the version of the application running under .NET 2.0 or .NET 4.0.

The solution for me was to re-register ASP.NET against IIS.

I used the following command line to achieve this...

C:\Windows\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

And if you want to put it into string within some text context, forget about + operator. Simply do:

// Qt 5 + C++11
auto i = 13;    
auto printable = QStringLiteral("My magic number is %1. That's all!").arg(i);

// Qt 5
int i = 13;    
QString printable = QStringLiteral("My magic number is %1. That's all!").arg(i);

// Qt 4
int i = 13;    
QString printable = QString::fromLatin1("My magic number is %1. That's all!").arg(i);

If all you want to do is display an iframe on a page, the simplest solution I was able to come up with doesn't require divs or flex stuff is:

html {
    width: 100%;
    height: 100%;
    display: table;
}

body {
    text-align: center;
    vertical-align: middle;
    display: table-cell;
}

And then the HTML is just:

<html>
  <body>
     <iframe ...></iframe>
  </body>
</html>

If this is all you need you don't need wrapper divs to do it. This works for text content and stuff, too.

Fiddle.

Also this looks even simpler.

You could use a combination of SUBSTR and INSTR as follows :

Example string : field = 'DE124028#@$1048708#@$000#@$536967136#@$'

The seperator being #@$.

To get the '1048708' for example :

If the field is of fixed length ( 7 here ) :

substr(field,instr(field,'#@$',1,1)+3,7)

If the field is of variable length :

substr(field,instr(field,'#@$',1,1)+3,instr(field,'#@$',1,2) - (instr(field,'#@$',1,1)+3)) 

You should probably look into SUBSTR and INSTR functions for more flexibility.

Tested in IE, Firefox, and Chrome.

In VB.NET while trying to connect to Rackspace's SSL port on 465 I encountered the same issue (requires implicit SSL). I made use of https://www.nuget.org/packages/MailKit/ in order to successfully connect.

The following is an example of an HTML email message.

Imports MailKit.Net.Smtp
Imports MailKit
Imports MimeKit

Sub somesub()
    Dim builder As New BodyBuilder()
    Dim mail As MimeMessage
    mail = New MimeMessage()
    mail.From.Add(New MailboxAddress("", c_MailUser))
    mail.To.Add(New MailboxAddress("", c_ToUser))
    mail.Subject = "Mail Subject"
    builder.HtmlBody = "<html><body>Body Text"
    builder.HtmlBody += "</body></html>"
      mail.Body = builder.ToMessageBody()

      Using client As New SmtpClient
        client.Connect(c_MailServer, 465, True)
        client.AuthenticationMechanisms.Remove("XOAUTH2") ' Do not use OAUTH2
        client.Authenticate(c_MailUser, c_MailPassword) ' Use a username / password to authenticate.

Uninstall all existing node packages. Update node and npm.As it is given in documentation as at least node v5.x.x and npm 3.x.x else it will cause errors .

Do npm clean. Then do npm install, npm start.

This solved the issue for me.

I've had issues with using SELECT last_insert_rowid() in a multithreaded environment. If another thread inserts into another table that has an autoinc, last_insert_rowid will return the autoinc value from the new table.

Here's where they state that in the doco:

If a separate thread performs a new INSERT on the same database connection while the sqlite3_last_insert_rowid() function is running and thus changes the last insert rowid, then the value returned by sqlite3_last_insert_rowid() is unpredictable and might not equal either the old or the new last insert rowid.

That's from sqlite.org doco

If you want to combine using AND (intersection), use merge:

first_name_relation.merge(last_name_relation)

If you want to combine using OR (union), use or^†:

first_name_relation.or(last_name_relation)

^† Only in ActiveRecord 5+; for 4.2 install the where-or backport.

Let me try to explain my understanding with the help of four examples. Java is pass-by-value, and not pass-by-reference

/**

Pass By Value

In Java, all parameters are passed by value, i.e. assigning a method argument is not visible to the caller.

*/

Example 1:

public class PassByValueString {
    public static void main(String[] args) {
        new PassByValueString().caller();
    }

    public void caller() {
        String value = "Nikhil";
        boolean valueflag = false;
        String output = method(value, valueflag);
        /*
         * 'output' is insignificant in this example. we are more interested in
         * 'value' and 'valueflag'
         */
        System.out.println("output : " + output);
        System.out.println("value : " + value);
        System.out.println("valueflag : " + valueflag);

    }

    public String method(String value, boolean valueflag) {
        value = "Anand";
        valueflag = true;
        return "output";
    }
}

Result

output : output
value : Nikhil
valueflag : false

Example 2:

/** * * Pass By Value * */

public class PassByValueNewString {
    public static void main(String[] args) {
        new PassByValueNewString().caller();
    }

    public void caller() {
        String value = new String("Nikhil");
        boolean valueflag = false;
        String output = method(value, valueflag);
        /*
         * 'output' is insignificant in this example. we are more interested in
         * 'value' and 'valueflag'
         */
        System.out.println("output : " + output);
        System.out.println("value : " + value);
        System.out.println("valueflag : " + valueflag);

    }

    public String method(String value, boolean valueflag) {
        value = "Anand";
        valueflag = true;
        return "output";
    }
}

Result

output : output
value : Nikhil
valueflag : false

Example 3:

/** This 'Pass By Value has a feeling of 'Pass By Reference'

Some people say primitive types and 'String' are 'pass by value' and objects are 'pass by reference'.

But from this example, we can understand that it is infact pass by value only, keeping in mind that here we are passing the reference as the value. ie: reference is passed by value. That's why are able to change and still it holds true after the local scope. But we cannot change the actual reference outside the original scope. what that means is demonstrated by next example of PassByValueObjectCase2.

*/

public class PassByValueObjectCase1 {

    private class Student {
        int id;

Our team uses dropbox for ad-hoc distribution which uses https but still our app was failing to install. After much trouble-shooting we realized that the title field is required too. Whenever we sent out a link without this field safari ignored the link and did not prompt the user to install. Sometimes for quick development tests we skipped over the title node in the xml and not populate it. In case this is helpful for anyone having this issue make sure that your .plist contains the following nodes populated:

      ....
     <string>software</string>
    <key>title</key>

I found this in the Cheetah source code (here)

htmlCodes = [
    ['&', '&'],
    ['<', '&lt;'],
    ['>', '&gt;'],
    ['"', '&quot;'],
]
htmlCodesReversed = htmlCodes[:]
htmlCodesReversed.reverse()
def htmlDecode(s, codes=htmlCodesReversed):
    """ Returns the ASCII decoded version of the given HTML string. This does
        NOT remove normal HTML tags like <p>. It is the inverse of htmlEncode()."""
    for code in codes:
        s = s.replace(code[1], code[0])
    return s

not sure why they reverse the list, I think it has to do with the way they encode, so with you it may not need to be reversed. Also if I were you I would change htmlCodes to be a list of tuples rather than a list of lists... this is going in my library though :)

i noticed your title asked for encode too, so here is Cheetah's encode function.

def htmlEncode(s, codes=htmlCodes):
    """ Returns the HTML encoded version of the given string. This is useful to
        display a plain ASCII text string on a web page."""
    for code in codes:
        s = s.replace(code[0], code[1])
    return s

@inoabrian solution above worked for me. I ran into a situation where I would refresh my page and my hidden element would reappear on my page. Here's what I did to resolve it.

export class FooterComponent implements OnInit {
public showJoinTodayBtn: boolean = null;

ngOnInit() {
      if (condition is true) {
        this.showJoinTodayBtn = true;
      } else {
        this.showJoinTodayBtn = false;
      }
}

let's think urls = "http://example1.com http://example2.com"

function somefunction(urls){
var urlarray = urls.split(" ");
var text = "\"'" + urlarray[0] + "'\"";
}

output will be text = "'http://example1.com'"

For csv file formate data will be in below format

"column1", "column2","column3","column4"

And if we will use field terminated by ',' then each column will get values like below.

"column1"    "column2"     "column3"     "column4"

also if any of the column value has comma as value then it will not work at all .

So the correct way to create a table would be by using OpenCSVSerde

create table tableName (column1 datatype, column2 datatype , column3 datatype , column4 datatype)
ROW FORMAT SERDE 
'org.apache.hadoop.hive.serde2.OpenCSVSerde' 
STORED AS TEXTFILE ;

     return NULL;

void in_progress_feedback(int prog_delay){

    int i=0;
    for(;i<prog_delay;i++){
    printf(". ");
    sleep(1);
    fflush(stdout);
    }

    printf("\n");
    fflush(stdout);

    pthread_t tid0,tid1;
    pthread_mutex_init(&mutex, NULL);
    pthread_create(&tid0, NULL, compute, NULL);
    pthread_create(&tid1, NULL, compute, NULL);
    pthread_join(tid0, NULL);
    pthread_join(tid1, NULL);
    printf("global = %d\n", global);
    pthread_mutex_destroy(&mutex);
          return 0;
}

Because the column being sorted on (Range) is a string, string/word sorting is used instead of numeric sorting.

As long as the strings have zeros to pad out the number lengths the sorting should still be semantically correct:

SELECT t.range AS ScoreRange,
       COUNT(*) AS NumberOfOccurrences
  FROM (SELECT CASE
                    WHEN score BETWEEN 0 AND 9 THEN '00-09'
                    WHEN score BETWEEN 10 AND 19 THEN '10-19'
                    ELSE '20-99'
               END AS Range
          FROM Scores) t
 GROUP BY t.Range

If the range is mixed, simply pad an extra zero:

SELECT t.range AS ScoreRange,
       COUNT(*) AS NumberOfOccurrences
  FROM (SELECT CASE
                    WHEN score BETWEEN 0 AND 9 THEN '000-009'
                    WHEN score BETWEEN 10 AND 19 THEN '010-019'
                    WHEN score BETWEEN 20 AND 99 THEN '020-099'
                    ELSE '100-999'
               END AS Range
          FROM Scores) t
 GROUP BY t.Range

On Windows Subsystem for Linux (WSL) this was the only solution that I found to work:

eval `ssh-agent` ; ssh-add ~/.ssh/id_rsa

It was a problem with the ssh-agent not being properly registered in WSL.

Conda needs to know where to find you SSL certificate store.

conda config --set ssl_verify <pathToYourFile>.crt

No need to disable SSL verification.

This command add a line to your $HOME/.condarc file or %USERPROFILE%\.condarc file on Windows that looks like:

ssl_verify: <pathToYourFile>.crt

If you leave your organization's network, you can just comment out that line in .condarc with a # and uncomment when you return.

If it still doesn't work, make sure that you are using the latest version of curl, checking both the conda-forge and anaconda channels.

You can use following code too:

 foreach (var item in listBox1.Items.Cast<string>().ToList())
 {
     string removelistitem = "OBJECT";
     if (item.Contains(removelistitem))
     {
        listBox1.Items.Remove(item);
     }
 }

Just for completeness, since MySQL and Postgres have already been mentioned: With SQLite, use "pragma table_info()"

sqlite> pragma table_info('table_name');
cid         name        type        notnull     dflt_value  pk        
----------  ----------  ----------  ----------  ----------  ----------
0           id          integer     99                      1         
1           name                    0                       0         

If you're looking for a JS version (using a combination of feature detection and UA sniffing) of what html5 boilerplate used to do:

var IE = (!! window.ActiveXObject && +(/msie\s(\d+)/i.exec(navigator.userAgent)[1])) || NaN;
if (IE < 9) {
    document.documentElement.className += ' lt-ie9' + ' ie' + IE;
}

write the query: truncate 'Your_table_name';

You can use :+ to append element to array and +: to prepend it:

0 +: array :+ 4

should produce:

res3: Array[Int] = Array(0, 1, 2, 3, 4)

It's the same as with any other implementation of Seq.

You can use the environment variable $HOME for that.

Although I am not sure if this is the result you expect, you can save your DataFrame in png by plotting the DataFrame with Seaborn Heatmap with annotations on, like this:

http://stanford.edu/~mwaskom/software/seaborn/generated/seaborn.heatmap.html#seaborn.heatmap

It works right away with a Pandas Dataframe. You can look at this example: Efficiently ploting a table in csv format using Python

You might want to change the colormap so it displays a white background only.

Hope this helps.

Use

git show --summary `git merge-base foo master`

If you’d rather see it in context using gitk, then use

gitk --all --select-commit=`git merge-base foo master`

(where foo is the name of the branch you are looking for.)

Try this:

paramstr.Remove((paramstr.Length-1),1);

I ran into the same issue. Daniel Nugent's answer helped a bit (after following his advice HttpResponse was found - but the HttpClient was still missing).

So here is what fixed it for me:

1. (if not already done, commend previous import-statements out)
2. visit http://hc.apache.org/downloads.cgi
3. get the 4.5.1.zip from the binary section
4. unzip it and paste httpcore-4.4.3 & httpclient-4.5.1.jar in project/libs folder
5. right-click the jar and choose Add as library.

Hope it helps.

The below code gets the full path, where the anchor points:

document.getElementById("aaa").href; // http://example.com/sec/IF00.html

while the one below gets the value of the href attribute:

document.getElementById("aaa").getAttribute("href"); // sec/IF00.html

for (i>0; i--;)

is probably wrong and should be

for (; i>0; i--)

instead. Note where I put the semicolons. The condition goes in the middle, not at the start.

Edit. As noted in the comments, this is no longer working with the latest Android Studio releases.

The latest Android studio seems to only reference to "Offline mode" via the keymap, but toggling this does not seem to change anything anymore.

In Android Studio open the settings and search for offline it will find the Gradle category which contains Offline work. You can disable it there.

Error reporting will have not included notices on the previous server which is why you haven't seen the errors.

You should be checking whether the index s actually exists in the $_GET array before attempting to use it.

Something like this would be suffice:

if (isset($_GET['s'])) {
    if ($_GET['s'] == 'jwshxnsyllabus')
        echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml',         '../bibliographies/jwshxnbibliography_')\">";
    else if ($_GET['s'] == 'aquinas')
        echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">"; 
    else if ($_GET['s'] == 'POP2')
        echo "<body onload=\"loadSyllabi('POP2')\">";
} else {
    echo "<body>";
}

It may be beneficial (if you plan on adding more cases) to use a switch statement to make your code more readable.

switch ((isset($_GET['s']) ? $_GET['s'] : '')) {
    case 'jwshxnsyllabus':
        echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml',         '../bibliographies/jwshxnbibliography_')\">";
        break;
    case 'aquinas':
        echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">";
        break;
    case 'POP2':
        echo "<body onload=\"loadSyllabi('POP2')\">";
        break;
    default:
        echo "<body>";
        break;
}

EDIT: BTW, the first set of code I wrote mimics what yours is meant to do in it's entirety. Is the expected outcome of an unexpected value in ?s= meant to output no <body> tag or was this an oversight? Note that the switch will fix this by always defaulting to <body>.

You can try with:

    display: inline-table;

For me it works fine.

You can use display:inline-block instead of float and vertical-align:middle with this CSS:

.col-lg-4, .col-lg-8 {
    float:none;
    display:inline-block;
    vertical-align:middle;
    margin-right:-4px;
}

The demo http://bootply.com/94402

print "bla: ", $_, "\n" if ($_ = $myvar) =~ s/a/b/g or 1;

If you mean that both ProductName fields are to have the same value, then:

SELECT a.ProductName,a.NumberofProducts,b.ProductName,b.NumberofProductsSold FROM Table1 a, Table2 b WHERE a.ProductName=b.ProductName;

Or, if you want the ProductName column to be displayed only once,

SELECT a.ProductName,a.NumberofProducts,b.NumberofProductsSold FROM Table1 a, Table2 b WHERE a.ProductName=b.ProductName;

Otherwise,if any row of Table1 can be associated with any row from Table2 (even though I really wonder why anyone'd want to do that), you could give this a look.

Easy way to use for create dynamic header and cell in normal table :

<table width="100%" class="table">

  </tr>
 </thead>
 <tbody>
  <tr ng-repeat="row in MyRecCollection | filter:searchText">
   <td ng-repeat="cell in row">{{cell}}</td>
  </tr>
 </tbody>
</table>

MyApp.controller('dataShow', function ($scope, $http) {
    //$scope.gridheader = ['Name','City','Country']
        $http.get('http://www.w3schools.com/website/Customers_MYSQL.php').success(function (data) {

                $scope.MyRecCollection = data;
        })

1st Understand the java.util.Date class

1.1 How to obtain current Date

import java.util.Date;

class Demostration{
    public static void main(String[]args){
        Date date = new Date(); // date object
        System.out.println(date); // Try to print the date object
    }
}

1.2 How to use getTime() method

import java.util.Date;
public class Main {
    public static void main(String[]args){
        Date date = new Date();
        long timeInMilliSeconds = date.getTime();
        System.out.println(timeInMilliSeconds);
    }
}

This will return the number of milliseconds since January 1, 1970, 00:00:00 GMT for time comparison purposes.

1.3 How to format time using SimpleDateFormat class

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;

class Demostration{
    public static void main(String[]args){
        Date date=new Date();
        DateFormat dateFormat=new SimpleDateFormat("yyyy-MM-dd");
        String formattedDate=dateFormat.format(date);
        System.out.println(formattedDate);
    }
}

Also try using different format patterns like "yyyy-MM-dd hh:mm:ss" and select desired pattern. http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

2nd Understand the java.util.Calendar class

2.1 Using Calendar Class to obtain current time stamp

import java.util.Calendar;

class Demostration{
    public static void main(String[]args){
        Calendar calendar=Calendar.getInstance();
        System.out.println(calendar.getTime());
    }
}

2.2 Try using setTime and other set methods for set calendar to different date.

Update 2020:

There are several options available*:

*Disclaimer: This list may not be complete.

Using Flexbox
Nowadays, we can use flexbox. It is quite a handy alternative to the css-transform option. I would use this solution almost always. If it is just one element maybe not, but for example if I had to support an array of data e.g. rows and columns and I want them to be relatively centered in the very middle.

.flexbox {
  display: flex;
  height: 100px;
  flex-flow: row wrap;
  align-items: center;
  justify-content: center;
  background-color: #eaeaea;
  border: 1px dotted #333;
}

.item {
  /* default => flex: 0 1 auto */
  background-color: #fff;
  border: 1px dotted #333;
  box-sizing: border-box;
}

<div class="flexbox">
  <div class="item">I am centered in the middle.</div>
  <div class="item">I am centered in the middle, too.</div>
</div>

Using CSS 2D-Transform
This is still a good option, was also the accepted solution back in 2015. It is very slim and simple to apply and does not mess with the layouting of other elements.

.boxes {
  position: relative;
}

.box {
  position: relative;
  display: inline-block;
  float: left;
  width: 200px;
  height: 200px;
  font-weight: bold;
  color: #333;
  margin-right: 10px;
  margin-bottom: 10px;
  background-color: #eaeaea;
}

.h-center {
  text-align: center;
}

.v-center span {
  position: absolute;
  left: 0;
  right: 0;
  top: 50%;
  transform: translate(0, -50%);
}

<div class="boxes">
  <div class="box h-center">horizontally centered lorem ipsun dolor sit amet</div>
  <div class="box v-center"><span>vertically centered lorem ipsun dolor sit amet lorem ipsun dolor sit amet</span></div>
  <div class="box h-center v-center"><span>horizontally and vertically centered lorem ipsun dolor sit amet</span></div>
</div>

Note: This does also work with :after and :before pseudo-elements.

Using Grid
This might just be an overkill, but it depends on your DOM. If you want to use grid anyway, then why not. It is very powerful alternative and you are really maximum flexible with the design.

Note: To align the items vertically we use flexbox in combination with grid. But we could also use display: grid on the items.

.grid {
  display: grid;
  width: 400px;
  grid-template-rows: 100px;
  grid-template-columns: 100px 100px 100px;
  grid-gap: 3px;
  align-items: center;
  justify-content: center;
  background-color: #eaeaea;
  border: 1px dotted #333;
}

.item {
  display: flex;
  justify-content: center;
  align-items: center;
  border: 1px dotted #333;
  box-sizing: border-box;
}

.item-large {
  height: 80px;
}

<div class="grid">
  <div class="item">Item 1</div>
  <div class="item item-large">Item 2</div>
  <div class="item">Item 3</div>
</div>

Based on solution You've already found How to apply CSS to iframe?:

var cssLink = document.createElement("link") 
cssLink.href = "file://path/to/style.css"; 
cssLink .rel = "stylesheet"; 
cssLink .type = "text/css"; 
frames['iframe'].document.body.appendChild(cssLink);

or more jqueryish (from Append a stylesheet to an iframe with jQuery):

var $head = $("iframe").contents().find("head");                
$head.append($("<link/>", 
    { rel: "stylesheet", href: "file://path/to/style.css", type: "text/css" }));

Updated answer now that xyo.net has been bought and shut down.

appannie.com and similarweb.com are the best options now. Thanks @rinogo for the original suggestion!

Outdated answer:

Site is still buggy, but this is by far the best that I've found. Not sure if it's accurate, but at least they give you numbers that you can guess off of! They have numbers for Android, iOS (iPhone and iPad) and even Windows!

You probably just need to see the ASCII and EXTENDED ASCII character sets. As far as I know any of these are allowed in a char/varchar field.

If you use nchar/nvarchar then it's pretty much any character in any unicode set in the world.

I did this in iOS 4 using a block. Had to cast the elements of my array from id to my class type. In this case it was a class called Score with a property called points.

Also you need to decide what to do if the elements of your array are not the right type, for this example I just returned NSOrderedSame, however in my code I though an exception.

NSArray *sorted = [_scores sortedArrayUsingComparator:^(id obj1, id obj2){
    if ([obj1 isKindOfClass:[Score class]] && [obj2 isKindOfClass:[Score class]]) {
        Score *s1 = obj1;
        Score *s2 = obj2;

        if (s1.points > s2.points) {
            return (NSComparisonResult)NSOrderedAscending;
        } else if (s1.points < s2.points) {
            return (NSComparisonResult)NSOrderedDescending;
        }
    }

    // TODO: default is the same?
    return (NSComparisonResult)NSOrderedSame;
}];

return sorted;

PS: This is sorting in descending order.

And there might be some methods doing that in Excel.

You should remove navbar-fixed-top class otherwise navbar stays fixed on top of page where you want logo.

If you want to place logo inside navbar:

Navbar height (set in @navbarHeight LESS variable) is 40px by default. Your logo has to fit inside or you have to make navbar higher first.

Then use brand class:

<div class="navbar navbar-fixed-top">
  <div class="navbar-inner">
    <div class="container">
      <a href="/" class="brand"><img alt="" src="/logo.gif" /></a>
    </div>
  </div>
</div>

If your logo is higher than 20px, you have to fix stylesheets as well.

If you do that in LESS:

.navbar .brand {
  @elementHeight: 32px;
  padding: ((@navbarHeight - @elementHeight) / 2 - 2) 20px ((@navbarHeight - @elementHeight) / 2 + 2);
}

@elementHeight should be set to your image height.

Padding calculation is taken from Twitter Bootstrap LESS - https://github.com/twitter/bootstrap/blob/v2.0.4/less/navbar.less#L51-52

Alternatively you can calculate padding values yourself and use pure CSS.

This works for Twitter Bootstrap versions 2.0.x, should work in 2.1 as well, but padding calculation was changed a bit: https://github.com/twitter/bootstrap/blob/v2.1.0/less/navbar.less#L50

Javascript now has a specific built in object called Map, you can call as follows :

   var myMap = new Map()

You can update it with .set :

   myMap.set("key0","value")

This has the advantage of methods you can use to handle look ups, like the boolean .has

  myMap.has("key1"); // evaluates to false 

You can use this before calling .get on your Map object to handle looking up non-existent keys

You need to use the document.getElementsByClassName('class_name');

and dont forget that the returned value is an array of elements so if you want the first one use:

document.getElementsByClassName('class_name')[0]

UPDATE

Now you can use:

document.querySelector(".class_name") to get the first element with the class_name CSS class (null will be returned if non of the elements on the page has this class name)

or document.querySelectorAll(".class_name") to get a NodeList of elements with the class_name css class (empty NodeList will be returned if non of. the elements on the the page has this class name).

This code uses cv2.putText to overlay text on an image. You need NumPy and OpenCV installed.

import numpy as np
import cv2

# Create a black image
img = np.zeros((512,512,3), np.uint8)

# Write some Text

font                   = cv2.FONT_HERSHEY_SIMPLEX
bottomLeftCornerOfText = (10,500)
fontScale              = 1
fontColor              = (255,255,255)
lineType               = 2

cv2.putText(img,'Hello World!', 
    bottomLeftCornerOfText, 
    font, 
    fontScale,
    fontColor,
    lineType)

#Display the image
cv2.imshow("img",img)

#Save image
cv2.imwrite("out.jpg", img)

Convert inputstream into bytes and then pass it to savefile function where you assemble the same into inputstream. Also in original function use bytes to use for other tasks

Please refer the following link for better understanding about the difference between Const pointer and Pointer on a constant value.

constant pointer vs pointer on a constant value

I would do the following (copy-paste the whole stuff below into immediate window / query window and execute)

DECLARE @foo int
DECLARE @unclefoo smalldatetime
SET @foo = DATEDIFF(minute, CAST('2013.01.01 00:00:00' AS datetime),CAST('2013.01.01 00:03:59' AS datetime)) -- AS 'Duration (Minutes)'

SET @unclefoo = DATEADD(minute, @foo, '2000.01.01')

SELECT CAST(@unclefoo AS time)

@foo stores the value you generate in your question. The "trick" comes by then:
we create a smalldatetime variable (in my case it's yyyy.mm.dd format) and increment it with your int value, then display (or store if you want) the time part only.

switch(message)
{
  case "test":
    Console.WriteLine("yes");
    break;                
  default:
    if (Contains("test2")) {
      Console.WriteLine("yes for test2");
    }
    break;
}

Simple:

Use <section>.

and use <a href="page.html#tips">Visit the Useful Tips Section</a>

The code can be

<div class="text-class"><span>hello</span><span>How are you</span></div>

CSS would be

.text-class {
     display: flex;
     justify-content: flex-start;
     flex-direction: column;
     align-items: center;
 }

git checkout -b new-branch-name
git push remote-name new-branch-name :old-branch-name

You may have to manually switch to new-branch-name before deleting old-branch-name

You can only have one ID per element, but you can indeed have more than one class. But don't have multiple class attributes, put multiple class values into one attribute.

<div id="foo" class="bar baz bax">

is perfectly legal.

In my case it was because of my 4K screen too thin to read. Then u need to change from monospace In my case it was because of my 4K screen too thin to read. Then u need to change from Monospaced to Consolas.

I get get the same minicom error, "cannot open /dev/ttyUSB0: No such file or directory"

Three notes:

1. I get the error when the device attached to the serial port end of my Prolific Technology PL2303 USB/Serial adapter is turned off. After turning on the device (an embedded controller running Linux) minicom connected fine.

2. I have to run as super user (i.e. sudo minicom)

3. Sometimes I have to unplug and plug back in the USB-to-serial adapter to get minicom to connect to it.

I am running Ubuntu 10.04 LTS (Lucid Lynx) under VMware (running on Windows 7). In this situation, make sure the device is attached to VM operating system by right clicking on the USB/Serial USB icon in the lower right of the VMware window and select Connect (Disconnect from Host).

Remember to press Ctrl + A to get minicom's prompt, and type X to exit the program. Just exiting the terminal session running minicom will leave the process running.
