Another variation you can try is(expanding @mnel's answer) if you have many temp'x'.

here "n" could be the number of temp variables present

rm(list = c(paste("temp",c(1:n),sep="")))

For simplicity, if you do not want send a message, try this

$new_string = substr( $dynamicstring, -min( strlen( $dynamicstring ), 7 ) );

Well, there are plenty of database tutorials online for java (what you're looking for is called JDBC). But if you are using plain servlets, you will have a class that extends HttpServlet and inside it you will have two methods that look like

public void doPost(HttpServletRequest req, HttpServletResponse resp){

}

and

public void doGet(HttpServletRequest req, HttpServletResponse resp){

}

One of them is called to handle GET operations and another is used to handle POST operations. You will then use the HttpServletRequest object to get the parameters that were passed as part of the form like so:

String name = req.getParameter("name");

Then, once you have the data from the form, it's relatively easy to add it to a database using a JDBC tutorial that is widely available on the web. I also suggest searching for a basic Java servlet tutorial to get you started. It's very easy, although there are a number of steps that need to be configured correctly.

You can use Collections.sort method. It's a static method. You pass it the list and a comparator. It uses a modified mergesort algorithm over the list. That's why you must pass it a comparator to do the pair comparisons.

Collections.sort(myList, new Comparator<MyObject> {
   public int compare(MyObject o1, MyObject o2) {
      DateTime a = o1.getDateTime();
      DateTime b = o2.getDateTime();
      if (a.lt(b)) 
        return -1;
      else if (a.lteq(b)) // it's equals
         return 0;
      else
         return 1;
   }
});

Note that if myList is of a comparable type (one that implements Comparable interface) (like Date, Integer or String) you can omit the comparator and the natural ordering will be used.

import java.lang.String;

This is an unnecessary import. java.lang classes are always implicitly imported. This means that you do not have to import them manually (explicitly).

The other way is to create Indexes for your collection and make sure that they are unique.

You can find more on the following link

I actually find this pretty simple and easy to implement.

The error message seems self-explanatory. You can't instantiate an instance of an interface, and you've declared IUser as an interface. (The same rule applies to abstract classes.) The whole point of an interface is that it doesn't do anything—there is no implementation provided for its methods.

However, you can instantiate an instance of a class that implements that interface (provides an implementation for its methods), which in your case is the User class.

Thus, your code needs to look like this:

IUser user = new User();

This instantiates an instance of the User class (which provides the implementation), and assigns it to an object variable for the interface type (IUser, which provides the interface, the way in which you as the programmer can interact with the object).

Of course, you could also write:

User user = new User();

which creates an instance of the User class and assigns it to an object variable of the same type, but that sort of defeats the purpose of a defining a separate interface in the first place.

Here's an example that actually filters for BIN files. Also Windows now want you to save files to user locations, not system locations, so here's an example (you can use intellisense to browse the other options):

            var saveFileDialog = new Microsoft.Win32.SaveFileDialog()
            {
                DefaultExt = "*.xml",
                Filter = "BIN Files (*.bin)|*.bin",
                InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
            };

            var result = saveFileDialog.ShowDialog();
            if (result != null && result == true)
            {
                // Save the file here
            }

Find the below code to make visible the view in Circuler reveal, if you send true, it'll get Invisible/Gone. If you send false, it'll get visible. anyView is the view you're going to visible/hide, it could be any view (Layouts, Buttons etc)

 private fun toggle(flag: Boolean, anyView: View) {
    if (flag) {
        val cx = anyView.width / 2
        val cy = anyView.height / 2
        val initialRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
        val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, initialRadius, 0f)
        anim.addListener(object : AnimatorListenerAdapter() {
            override fun onAnimationEnd(animation: Animator) {
                super.onAnimationEnd(animation)
                anyView.visibility = View.INVISIBLE
            }
        })
        anim.start()
    } else {
        val cx = anyView.width / 2
        val cy = anyView.height / 2
        val finalRadius = Math.hypot(cx.toDouble(), cy.toDouble()).toFloat()
        val anim = ViewAnimationUtils.createCircularReveal(anyView, cx, cy, 0f, finalRadius)
        anyView.visibility = View.VISIBLE
        anim.start()
    }
}

I like this approach because it is simple and clean:

    String getCompaniesIdAndName = " select "
            + " c.id as id, "
            + " c.name as name "
            + " from Company c ";

    @Query(value = getCompaniesWithoutAccount)
    Set<CompanyIdAndName> findAllIdAndName();

    public static interface CompanyIdAndName extends DTO {
        Integer getId();

        String getName();

    }

PostgreSQL:

CREATE TABLE ud (id integer, assid integer);
CREATE TABLE sales (id integer, udid integer, assid integer);

UPDATE ud
SET assid = sales.assid
FROM sales
WHERE sales.id = ud.id;

For windows: Best is to use pre-compiled package available from this site: http://www.lfd.uci.edu/%7Egohlke/pythonlibs/#scipy

In Linux you can do like this

pg_dump -U postgres -s postgres > exportFile.dmp

Maybe it can work in Windows too, if not try the same with pg_dump.exe

pg_dump.exe -U postgres -s postgres > exportFile.dmp

Handling Commas

For handling commas inside of values when using string.Format(...), the following has worked for me:

var newLine = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                              first,
                              second,
                              third                                    
                              );
csv.AppendLine(newLine);

So to combine it with Johan's answer, it'd look like this:

//before your loop
var csv = new StringBuilder();

//in your loop
  var first = reader[0].ToString();
  var second = image.ToString();
  //Suggestion made by KyleMit
  var newLine = string.Format("\"{0}\",\"{1}\"", first, second);
  csv.AppendLine(newLine);  

//after your loop
File.WriteAllText(filePath, csv.ToString());

Returning CSV File

If you simply wanted to return the file instead of writing it to a location, this is an example of how I accomplished it:

From a Stored Procedure

public FileContentResults DownloadCSV()
{
  // I have a stored procedure that queries the information I need
  SqlConnection thisConnection = new SqlConnection("Data Source=sv12sql;User ID=UI_Readonly;Password=SuperSecure;Initial Catalog=DB_Name;Integrated Security=false");
  SqlCommand queryCommand = new SqlCommand("spc_GetInfoINeed", thisConnection);
  queryCommand.CommandType = CommandType.StoredProcedure;

  StringBuilder sbRtn = new StringBuilder();

  // If you want headers for your file
  var header = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                             "Name",
                             "Address",
                             "Phone Number"
                            );
  sbRtn.AppendLine(header);

  // Open Database Connection
  thisConnection.Open();
  using (SqlDataReader rdr = queryCommand.ExecuteReader())
  {
    while (rdr.Read())
    {
      // rdr["COLUMN NAME"].ToString();
      var queryResults = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                                        rdr["Name"].ToString(),
                                        rdr["Address"}.ToString(),
                                        rdr["Phone Number"].ToString()
                                       );
      sbRtn.AppendLine(queryResults);
    }
  }
  thisConnection.Close();

  return File(new System.Text.UTF8Encoding().GetBytes(sbRtn.ToString()), "text/csv", "FileName.csv");
}

From a List

/* To help illustrate */
public static List<Person> list = new List<Person>();

/* To help illustrate */
public class Person
{
  public string name;
  public string address;
  public string phoneNumber;
}

/* The important part */
public FileContentResults DownloadCSV()
{
  StringBuilder sbRtn = new StringBuilder();

  // If you want headers for your file
  var header = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                             "Name",
                             "Address",
                             "Phone Number"
                            );
  sbRtn.AppendLine(header);

  foreach (var item in list)
  {
      var listResults = string.Format("\"{0}\",\"{1}\",\"{2}\"",
                                        item.name,
                                        item.address,
                                        item.phoneNumber
                                       );
      sbRtn.AppendLine(listResults);
    }
  }

  return File(new System.Text.UTF8Encoding().GetBytes(sbRtn.ToString()), "text/csv", "FileName.csv");
}

Hopefully this is helpful.

Connection String

The connection string is a string of the form:

postgres://[user[:password]@][host][:port][/dbname]

(where the parts in [...] can optionally be included or excluded)

Some examples of valid connection strings include:

postgres://localhost
postgres://localhost:5432
postgres://localhost/mydb
postgres://user@localhost
postgres://user:secret_password@localhost

If you've just started a database on your local machine, the connection string postgres://localhost will typically work, as that uses the default port number, username, and no password. If the database was started with a specific account, you might find you need to use postgres://pg@localhost or postgres://postgres@localhost

If none of these work, and you have installed docker, another option is to run npx @databases/pg-test start. This will start a postgres server in a docker container and then print out the connection string for you. The pg-test databases are only intended for testing though, so you will loose all your data if your computer restarts.

Connecting in node.js

You can connect to the database and issue queries using @databases/pg:

const createPool = require('@databases/pg');
const {sql} = require('@databases/pg');

// If you're using TypeScript or Babel, you can swap
// the two `require` calls for this import statement:

// import createPool, {sql} from '@databases/pg';

// create a "pool" of connections, you can think of this as a single
// connection, the pool is just used behind the scenes to improve
// performance
const db = createPool('postgres://localhost');

// wrap code in an `async` function so we can use `await`
async function run() {

  // we can run sql by tagging it as "sql" and then passing it to db.query
  await db.query(sql`
    CREATE TABLE IF NOT EXISTS beatles (
      name TEXT NOT NULL,
      height INT NOT NULL,
      birthday DATE NOT NULL
    );
  `);

  const beatle = {
    name: 'George',
    height: 70,
    birthday: new Date(1946, 02, 14),
  };

  // If we need to pass values, we can use ${...} and they will
  // be safely & securely escaped for us
  await db.query(sql`
    INSERT INTO beatles (name, height, birthday)
    VALUES (${beatle.name}, ${beatle.height}, ${beatle.birthday});
  `);

  console.log(
    await db.query(sql`SELECT * FROM beatles;`)
  );
}

run().catch(ex => {
  // It's a good idea to always report errors using
  // `console.error` and set the process.exitCode if
  // you're calling an async function at the top level
  console.error(ex);
  process.exitCode = 1;
}).then(() => {
  // For this little demonstration, we'll dispose of the
  // connection pool when we're done, so that the process
  // exists. If you're building a web server/backend API
  // you probably never need to call this.
  return db.dispose();
});

You can find a more complete guide to querying Postgres using node.js at https://www.atdatabases.org/docs/pg

In C

 int a[]={10,20,30,40,50};
 int *p=a;
 printf("%d\n",*p++);//output will be 10
 printf("%d\n",*a++);//will give an error

Pointer p is a "variable", array name a is a "mnemonic" or "synonym", so p++ is valid but a++ is invalid.

a[2] is equals to 2[a] because the internal operation on both of this is "Pointer Arithmetic" internally calculated as *(a+2) equals *(2+a)

First, learn the core concepts of Node.js:

• You'll want to understand the asynchronous coding style that Node.js encourages.

• Async != concurrent. Understand Node.js's event loop!

• Node.js uses CommonJS-style require() for code loading; it's probably a bit different from what you're used to.

• Familiarize yourself with Node.js's standard library.

Then, you're going to want to see what the community has to offer:

The gold standard for Node.js package management is NPM.

• It is a command line tool for managing your project's dependencies.

• Make sure you understand how Node.js and NPM interact with your project via the node_modules folder and package.json.

• NPM is also a registry of pretty much every Node.js package out there

Finally, you're going to want to know what some of the more popular packages are for various tasks:

Useful Tools for Every Project:

• Underscore contains just about every core utility method you want.
• Lo-Dash is a clone of Underscore that aims to be faster, more customizable, and has quite a few functions that underscore doesn't have. Certain versions of it can be used as drop-in replacements of underscore.
• TypeScript makes JavaScript considerably more bearable, while also keeping you out of trouble!
• JSHint is a code-checking tool that'll save you loads of time finding stupid errors. Find a plugin for your text editor that will automatically run it on your code.

Unit Testing:

• Mocha is a popular test framework.
• Vows is a fantastic take on asynchronous testing, albeit somewhat stale.
• Expresso is a more traditional unit testing framework.
• node-unit is another relatively traditional unit testing framework.
• AVA is a new test runner with Babel built-in and runs tests concurrently.

Web Frameworks:

• Express.js is by far the most popular framework.
• Koa is a new web framework designed by the team behind Express.js, which aims to be a smaller, more expressive, and more robust foundation for web applications and APIs.
• sails.js the most popular MVC framework for Node.js, and is based on express. It is designed to emulate the familiar MVC pattern of frameworks like Ruby on Rails, but with support for the requirements of modern apps: data-driven APIs with a scalable, service-oriented architecture.
• Meteor bundles together jQuery, Handlebars, Node.js, WebSocket, MongoDB, and DDP and promotes convention over configuration without being a Ruby on Rails clone.
• Tower (deprecated) is an abstraction of a top of Express.js that aims to be a Ruby on Rails clone.
• Geddy is another take on web frameworks.
• RailwayJS is a Ruby on Rails inspired MVC web framework.
• Sleek.js is a simple web framework, built upon Express.js.
• Hapi is a configuration-centric framework with built-in support for input validation, caching, authentication, etc.

• Trails is a modern web application framework. It builds on the pedigree of Rails and Grails to accelerate development by adhering to a straightforward, convention-based, API-driven design philosophy.

• Danf is a full-stack OOP framework providing many features in order to produce a scalable, maintainable, testable and performant applications and allowing to code the same way on both the server (Node.js) and client (browser) sides.

• Derbyjs is a reactive full-stack JavaScript framework. They are using patterns like reactive programming and isomorphic JavaScript for a long time.

• Loopback.io is a powerful Node.js framework for creating APIs and easily connecting to backend data sources. It has an Angular.js SDK and provides SDKs for iOS and Android.

Web Framework Tools:

• Jade is the HAML/Slim of the Node.js world
• EJS is a more traditional templating language.
• Don't forget about Underscore's template method!

Networking:

• Connect is the Rack or WSGI of the Node.js world.
• Request is a very popular HTTP request library.
• socket.io is handy for building WebSocket servers.

Command Line Interaction:

• minimist just command line argument parsing.
• Yargs is a powerful library for parsing command-line arguments.
• Commander.js is a complete solution for building single-use command-line applications.
• Vorpal.js is a framework for building mature, immersive command-line applications.
• Chalk makes your CLI output pretty.

Code Generators:

• Yeoman Scaffolding tool from the command-line.
• Skaffolder Code generator with visual and command-line interface. It generates a customizable CRUD application starting from the database schema or an OpenAPI 3.0 YAML file.

Work with streams:

• mississipi everything you miss about streams.
• https://github.com/calvinmetcalf/streams-a-love-story
• http://maxogden.com/node-streams.html
• https://github.com/substack/stream-handbook
• How streams help to raise Node.js performance

I solved this removing the various empty files that git fsck was detecting, and then running a simple git pull.

I find it disappointing that now that even filesystems implement journaling and other "transactional" techniques to keep the fs sane, git can get to a corrupted state (and not be able to recover by itself) because of a power failure or space on device.

Ultimate solution (works in SSRS 2012 too!)

Append the following script to the following file (on the SSRS Server)
C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\js\ReportingServices.js

function pageLoad() {    
    var element = document.getElementById("ctl31_ctl10");
    if (element) 
    {
        element.style.overflow = "visible"; 
    }
}

Note: As azzlak noted, the div's name isn't always ctl31_ctl10. For SQL 2012 tryctl32_ctl09 and for 2008 R2 try ctl31_ctl09. If this solution doesn't work, look at the HTML from your browser to see if the script has worked properly changing the overflow:auto property to overflow:visible.

Solution for ReportViewer control

Insert into .aspx page (or into a linked .css file, if available) this style line

#reportViewer_ctl09 {
  overflow:visible !important;
 }

Reason

Chrome and Safari render overflow:auto in different way respect to IE.

SSRS HTML is QuirksMode HTML and depends on IE 5.5 bugs. Non-IE browsers don't have the IE quirksmode and therefore render the HTML correctly

The HTML page produced by SSRS 2008 R2 reports contain a div which has overflow:auto style, and it turns report into an invisible report.

<div id="ctl31_ctl10" style="height:100%;width:100%;overflow:auto;position:relative;">

I can see reports on Chrome by manually changing overflow:auto to overflow:visible in the produced webpage using Chrome's Dev Tools (F12).

I love Tim's solution, it's easy and working.

But there is still a problem: any time the user change parameters (my reports use parameters!) AJAX refreshes the div, the overflow:auto tag is rewritten, and no script changes it.

This technote detail explains what is the problem:

This happens because in a page built with AJAX panels, only the AJAX panels change their state, without refreshing the whole page. Consequently, the OnLoad events you applied on the <body> tag are only fired once: the first time your page loads. After that, changing any of the AJAX panels will not trigger these events anymore.

User einarq suggested this solution:

Another option is to rename your function to pageLoad. Any functions with this name will be called automatically by asp.net ajax if it exists on the page, also after each partial update. If you do this you can also remove the onload attribute from the body tag

So wrote the improved script that is shown in the solution.

Try this

public static long Hextonumber(String hexval)
    {
        hexval="0x"+hexval;
//      String decimal="0x00000bb9";
        Long number = Long.decode(hexval);
//.......       System.out.println("String [" + hexval + "] = " + number);
        return number;
        //3001
    }

You must run your mysql by xampp-controle.exe in folder XAMPP. After that login:

mysql -u root

You can resolve this in several ways:

• Use g++ in stead of gcc: g++ -g -o MatSim MatSim.cpp
• Add -lstdc++: gcc -g -o MatSim MatSim.cpp -lstdc++
• Replace <string.h> by <string>

This is a linker problem, not a compiler issue. The same problem is covered in the question iostream linker error – it explains what is going on.

If you deploy your application in Apache (Linux server) so you can follow following steps : Follow following steps :

Step 1: ng build --prod --env=prod

Step 2. (Copy dist into server) then dist folder created, copy dist folder and deploy it in root directory of server.

Step 3. Creates .htaccess file in root folder and paste this in the .htaccess

 <IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.html$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.html [L]
</IfModule>

Probably:

git pull origin master

Here is a picture that shows the difference between add() and replace()

So add() method keeps on adding fragments on top of the previous fragment in FragmentContainer.

While replace() methods clears all the previous Fragment from Containers and then add it in FragmentContainer.

What is addToBackStack

addtoBackStack method can be used with add() and replace methods. It serves a different purpose in Fragment API.

What is the purpose?

Fragment API unlike Activity API does not come with Back Button navigation by default. If you want to go back to the previous Fragment then the we use addToBackStack() method in Fragment. Let's understand both

Case 1:

getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.fragmentContainer, fragment, "TAG")
            .addToBackStack("TAG")
            .commit();

Case 2:

getSupportFragmentManager()
            .beginTransaction()
            .add(R.id.fragmentContainer, fragment, "TAG")
            .commit();

Use this trick for grouped type tableView

Copy paste below code for your table view in viewDidLoad method:

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

I think you want this:

$('#recover-password').show();

or

$('#recover-password').toggle();

This is made possible by jQuery.

Try using:

real=$(realpath $(dirname $0))

We faced a similar situation in our company. None of the proposed methods did not help us. As a result of the research, the problem was revealed. The thing was that in Git there were two files, the names of which differed only in the register of symbols. Unix-systems saw them as two different files, but Windows was going crazy. To solve the problem, we deleted one of the files on the server. After that, at the local repositories on Windows helped the next few commands (in different sequences):

git reset --hard
git pull origin
git merge

I forgot that I had already an unused labs branch. Deleting it solved my problem:

git branch -d labs
git checkout -b labs/feature

Explanation:

Each name can only be a parent branch or a normal branch, not both. Thats why the branches labs and labs/feature can't exists both at the same time.

The reason: Branches are stored in the file system and there you also can't have a file labs and a directory labs at the same level.

This doesn't improve so much but...

The simplest (but not the fastest) way to iterate a directory tree and list relative file paths is to use FORFILES.

forfiles /s /m *.txt /c "cmd /c echo @relpath"

The relative paths will be quoted with a leading .\ as in

To remove quotes:

for /f %%A in ('forfiles /s /m *.txt /c "cmd /c echo @relpath"') do echo %%~A

To remove quotes and the leading .\:

setlocal disableDelayedExpansion

  set "file=%%~A"
  setlocal enableDelayedExpansion
  echo !file:~2!
  endlocal
)

or without using delayed expansion

for /f "tokens=1* delims=\" %%A in (
  'forfiles /s /m *.txt /c "cmd /c echo @relpath"'
) do for %%F in (^"%%B) do echo %%~F

Hope that helps :)

Edit: working example, http://jsfiddle.net/C5WxK/

If you want to ensure a file is closed you should use the block form of File.open:

File.open("myFile.txt", "w") do |file|
  begin
    file << "#{content} \n"
  rescue
  #handle the error here
  end
end

Click the Start menu and choose Run or use the keyboard shortcut of Win+R.

In the dialog box, type lusrmgr.msc. When this application opens, click Users in the left-hand panel and then right click Administrator in the right-hand panel. Click Properties in the menu.

In the Administrator Properties dialog, choose the Member Of tab, then click the Add... button at the lower right. From the next dialog, choose Advanced...

Another dialog will appear. From there click Find Now on the right. A list of search results will appear at the bottom of the dialog. Select Network Services from this list and click OK on each of the open dialogs.

This worked for me:

export _JAVA_OPTIONS="-Xmx1g"

It's important that you have no spaces because for me it did not work. I would suggest just copying and pasting. Then I ran:

java -XshowSettings:vm

and it will tell you:

Picked up _JAVA_OPTIONS: -Xmx1g

The output of ps aux looks like you did not start docker through systemd/systemctl.

It looks like you started it with:

sudo dockerd -H gridsim1103:2376

When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.

The correct way to start docker is to use systemd/systemctl:

systemctl enable docker
systemctl start docker

After this, docker should start on system start.

EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.

If you're trying to launch a specific activity instead of running the launcher one. When you select that activity. the android studio might through this error, Either you need to make it launcher activity, just like answered by few others. or you need to add android:exported="true" inside your activity tag inside manifest. It allows any external tool to run your specific activity directly without making it a launcher activity

ALTER TABLE is right:

ALTER TABLE MyCustomers ALTER COLUMN CompanyName VARCHAR(20) NULL

check this tip. worked for here http://mobeer.blogspot.com/2009/01/excel-2007-cannot-empty-clipboard.html:

This might save somebody some time and headaches if google picks it up. I was getting a 'Cannot empty the Clipboard' error every time I moved cells around in Excel - eventually I mucked around with the settings and made it go away. Here's how; In the excel main menu (glass globe w/logo), click Excel options, then Advanced, then turn off 'Show paste options buttons'

How exciting was this as my first post of the year?

Update: I still haven't found a permanent solution but I found another thing that seems to help. In Excel 2007, from the "home" tab, the first thing on the left is the clipboard tool panel. Expand the panel to view the clipboard and in the clipboard you might find "cannot empty clipboard" as an entry. Empty the clipboard, keep the panel open for a second or two while you do a few cut and pastes/drags etc. and then the bogey seems to go away.

I call this the cable dance because back in the day I had a printer that only worked if you unplugged the cable, shook it out and plugged it back in.

Could someone explain to me, how to call the move method with the variable RIGHT

>>> myMissile = MissileDevice(myBattery)  # looks like you need a battery, don't know what that is, you figure it out.
>>> myMissile.move(MissileDevice.RIGHT)

If you have programmed in any other language with classes, besides python, this sort of thing

class Foo:
    bar = "baz"

is probably unfamiliar. In python, the class is a factory for objects, but it is itself an object; and variables defined in its scope are attached to the class, not the instances returned by the class. to refer to bar, above, you can just call it Foo.bar; you can also access class attributes through instances of the class, like Foo().bar.

Im utterly baffled about what 'self' refers too,

>>> class Foo:
...     def quux(self):
...         print self
...         print self.bar
...     bar = 'baz'
...
>>> Foo.quux
<unbound method Foo.quux>
>>> Foo.bar
'baz'
>>> f = Foo()
>>> f.bar
'baz'
>>> f
<__main__.Foo instance at 0x0286A058>
>>> f.quux
<bound method Foo.quux of <__main__.Foo instance at 0x0286A058>>
>>> f.quux()
<__main__.Foo instance at 0x0286A058>
baz
>>>

When you acecss an attribute on a python object, the interpreter will notice, when the looked up attribute was on the class, and is a function, that it should return a "bound" method instead of the function itself. All this does is arrange for the instance to be passed as the first argument.

set vimdiff to ignore case

Having started vim diff with

 gvim -d main.sql backup.sql &

I find that annoyingly one file has MySQL keywords in lowercase the other uppercase showing differences on practically every other line

:set diffopt+=icase

this updates the screen dynamically & you can just as easily switch it off again

tree -L 2 -u -g -p -d

Prints the directory tree in a pretty format up to depth 2 (-L 2). Print user (-u) and group (-g) and permissions (-p). Print only directories (-d). tree has a lot of other useful options.

You don't need to disable ASLR in order to do a buffer overflow! Although ASLR is enabled (kernel_randomize_va_space = 2), it will not take effect unless the compiled executable is PIE. So unless you compiled your file with -fPIC -pie flag, ASLR will not take effect.

I think only disabling the canaries with -fno-stack-protector is enough. If you want to check if ASLR is working or not (Position independent code must be set), use:

hardening-check executable_name

Javascript has a built in JSON parse for strings, which I think is what you have:

var myObject = JSON.parse("my json string");

to use this with your example would be:

var jsonData = JSON.parse(myMessage);
for (var i = 0; i < jsonData.counters.length; i++) {
    var counter = jsonData.counters[i];
    console.log(counter.counter_name);
}

Here is a working example

EDIT: There is a mistake in your use of for loop (I missed this on my first read, credit to @Evert for the spot). using a for-in loop will set the var to be the property name of the current loop, not the actual data. See my updated loop above for correct usage

IMPORTANT: the JSON.parse method wont work in old old browsers - so if you plan to make your website available through some sort of time bending internet connection, this could be a problem! If you really are interested though, here is a support chart (which ticks all my boxes).

If you want to disable all the div's controls, you can try adding a transparent div on the div to disable, you gonna make it unclickable, also use fadeTo to create a disable appearance.

try this.

$('#DisableDiv').fadeTo('slow',.6);
$('#DisableDiv').append('<div style="position: absolute;top:0;left:0;width: 100%;height:100%;z-index:2;opacity:0.4;filter: alpha(opacity = 50)"></div>');

You can use parseInt(string, radix) to convert string value to integer like this code below

var votevalue = parseInt($('button').data('votevalue'));

The Spring documentation says they're logged at DEBUG level:

All SQL issued by this class is logged at the DEBUG level under the category corresponding to the fully qualified class name of the template instance (typically JdbcTemplate, but it may be different if you are using a custom subclass of the JdbcTemplate class).

In XML terms, you need to configure the logger something like:

<category name="org.springframework.jdbc.core.JdbcTemplate">
    <priority value="debug" />
</category>

This subject was however discussed here a month ago and it seems not as easy to get to work as in Hibernate and/or it didn't return the expected information: Spring JDBC is not logging SQL with log4j This topic under each suggests to use P6Spy which can also be integrated in Spring according this article.

From the C# Language specification:

1.7 Structs

Like classes, structs are data structures that can contain data members and function members, but unlike classes, structs are value types and do not require heap allocation. A variable of a struct type directly stores the data of the struct, whereas a variable of a class type stores a reference to a dynamically allocated object. Struct types do not support user-specified inheritance, and all struct types implicitly inherit from type object.

Structs are particularly useful for small data structures that have value semantics. Complex numbers, points in a coordinate system, or key-value pairs in a dictionary are all good examples of structs. The use of structs rather than classes for small data structures can make a large difference in the number of memory allocations an application performs. For example, the following program creates and initializes an array of 100 points. With Point implemented as a class, 101 separate objects are instantiated—one for the array and one each for the 100 elements.

class Point
{
   public int x, y;

   public Point(int x, int y) {
      this.x = x;
      this.y = y;
   }
}

class Test
{
   static void Main() {
      Point[] points = new Point[100];
      for (int i = 0; i < 100; i++) points[i] = new Point(i, i);
   }
}

An alternative is to make Point a struct.

struct Point
{
   public int x, y;

   public Point(int x, int y) {
      this.x = x;
      this.y = y;
   }
}

Now, only one object is instantiated—the one for the array—and the Point instances are stored in-line in the array.

Struct constructors are invoked with the new operator, but that does not imply that memory is being allocated. Instead of dynamically allocating an object and returning a reference to it, a struct constructor simply returns the struct value itself (typically in a temporary location on the stack), and this value is then copied as necessary.

With classes, it is possible for two variables to reference the same object and thus possible for operations on one variable to affect the object referenced by the other variable. With structs, the variables each have their own copy of the data, and it is not possible for operations on one to affect the other. For example, the output produced by the following code fragment depends on whether Point is a class or a struct.

Point a = new Point(10, 10);
Point b = a;
a.x = 20;
Console.WriteLine(b.x);

If Point is a class, the output is 20 because a and b reference the same object. If Point is a struct, the output is 10 because the assignment of a to b creates a copy of the value, and this copy is unaffected by the subsequent assignment to a.x.

The previous example highlights two of the limitations of structs. First, copying an entire struct is typically less efficient than copying an object reference, so assignment and value parameter passing can be more expensive with structs than with reference types. Second, except for ref and out parameters, it is not possible to create references to structs, which rules out their usage in a number of situations.

With Guava you can do:

Optional.fromNullable(a).or(b);

which doesn't throw NPE if both a and b are null.

EDIT: I was wrong, it does throw NPE. The correct way as commented by Michal Cizmazia is:

Optional.fromNullable(a).or(Optional.fromNullable(b)).orNull();

In cell A1, enter the time.
In cell B2, enter =A1+1/24

You will need to have some access to the Form's Instance to access its Controls collection and thereby changing the Text Box's Text.

One of ways could be that You can have a Your Form's Instance Available as Public or More better Create a new Constructor For your Second Form and have it receive the Form1's instance during initialization.

Of course you can.

One thing should be noted however: The INSERT INTO SELECT statement copies data from one table and inserts it into another table AND requires that data types in source and target tables match. If data types from given table columns does not match (i.e. trying to insert VARCHAR into INT, or TINYINT intoINT) the MySQL server will throw an SQL Error (1366).

So be careful.

Here is the syntax of the command:

INSERT INTO table2 (column1, column2, column3)
SELECT column1, column2, column3 FROM table1
WHERE condition;

Side note: There is a way to circumvent different column types insertion problem by using casting in your SELECT, for example:

SELECT CAST('qwerty' AS CHAR CHARACTER SET utf8) COLLATE utf8_bin;

This conversion (CAST() is synonym of CONVERT() ) is very useful if your tables have different character sets on the same table column (which can potentially lead to data loss if not handled properly).

I believe you could use SingletonBeanFactoryLocator. The beanRefFactory.xml file would hold the actual applicationContext, It would go something like this:

<bean id="mainContext" class="org.springframework.context.support.ClassPathXmlApplicationContext">
     <constructor-arg>
        <list>
            <value>../applicationContext.xml</value>
        </list>
     </constructor-arg>
 </bean>

And the code to get a bean from the applicationcontext from whereever would be something like this:

BeanFactoryLocator bfl = SingletonBeanFactoryLocator.getInstance();
BeanFactoryReference bf = bfl.useBeanFactory("mainContext");
SomeService someService = (SomeService) bf.getFactory().getBean("someService");

The Spring team discourage the use of this class and yadayada, but it has suited me well where I have used it.

Please check your web.xml again. You might be making some silly mistake. As my application is working fine with the same init-param configuration...

Please copy paste the web.xml, if the problem still persists.

Ori Drori's comment is correct, you aren't doing this the "React Way". In React, you should ideally not be changing classes and event handlers using the DOM. Do it in the render() method of your React components; in this case that would be the sideNav and your Header. A rough example of how this would be done in your code is as follows.

HEADER

class Header extends React.Component {
constructor(props){
    super(props);
}

render() {
    return (
        <div className="header">
            <i className="border hide-on-small-and-down"></i>
            <div className="container">
                <a ref="btn" href="#" className="btn-menu show-on-small"
                onClick=this.showNav><i></i></a>
                <Menu className="menu hide-on-small-and-down"/>
                <Sidenav ref="sideNav"/>
            </div>
        </div>
    )
}

showNav() {
  this.refs.sideNav.show();
}
}

SIDENAV

 class SideNav extends React.Component {
   constructor(props) {
     super(props);
     this.state = {
       open: false
     }
   }

   render() {
     if (this.state.open) {
       return ( 
         <div className = "sideNav">
            This is a sidenav 
         </div>
       )
     } else {
       return null;
     }

   }

   show() {
     this.setState({
       open: true
     })
   }
 }

You can see here that we are not toggling classes but using the state of the components to render the SideNav. This way, or similar is the whole premise of using react. If you are using bootstrap, there is a library which integrates bootstrap elements with the react way of doing things, allowing you to use the same elements but set state on them instead of directly manipulating the DOM. It can be found here - https://react-bootstrap.github.io/

Hope this helps, and enjoy using React!

class Program
{
    static void Main(string[] args)
    {

        int transactionDate = 20201010;
        int? transactionTime = 210000;

        var agreementDate = DateTime.Today;
        var previousDate = agreementDate.AddDays(-1);

        var agreementHour = 22;
        var agreementMinute = 0;
        var agreementSecond = 0;

        var startDate = new DateTime(previousDate.Year, previousDate.Month, previousDate.Day, agreementHour, agreementMinute, agreementSecond);
        var endDate = new DateTime(agreementDate.Year, agreementDate.Month, agreementDate.Day, agreementHour, agreementMinute, agreementSecond);

        DateTime selectedDate = Convert.ToDateTime(transactionDate.ToString().Substring(6, 2) + "/" + transactionDate.ToString().Substring(4, 2) + "/" + transactionDate.ToString().Substring(0, 4) + " " + string.Format("{0:00:00:00}", transactionTime));

        Console.WriteLine("Selected Date : " + selectedDate.ToString());
        Console.WriteLine("Start Date : " + startDate.ToString());
        Console.WriteLine("End Date : " + endDate.ToString());

        if (selectedDate > startDate && selectedDate <= endDate)
            Console.WriteLine("Between two dates..");
        else if (selectedDate <= startDate)
            Console.WriteLine("Less than or equal to the start date!");
        else if (selectedDate > endDate)
            Console.WriteLine("Greater than end date!");
        else
            Console.WriteLine("Out of date ranges!");
    }
}

There are three reasons why your example fails.

1. The original 'template' variable is not a jQuery/DOM object and cannot be parsed, it is a string. Make it a jQuery object by wrapping it in $(), such as: template = $(template)

2. Once the 'template' variable is a jQuery object you need to realize that <li> is the root object. Therefore you cannot search for the LI root node and get any results. Simply apply the ID to the jQuery object.

3. When you assign an ID to an HTML element it cannot begin with a number character with any HTML version before HTML5. It must begin with an alphabetic character. With HTML5 this can be any non-whitespace character. For details refer to: What are valid values for the id attribute in HTML?

PS: A final issue with the sample code is an LI cannot be applied to the BODY. According to HTML requirements it must always be contained within a list, i.e. UL or OL.

or in a better way we can have like this

Let's say your primary key is an Integer and object you save is "ticket", then you can get it like this. When you save the object, id is always returned

//unboxing will occur here so that id here will be value type not the reference type. Now you can check id for 0 in case of save failure. like below:

int id = (Integer) session.save(ticket); 
if(id==0) 
   your session.save call was not success. 
else '
   your call to session.save was successful.

Indeed, it is O(n^2). See also a very similar example with the same runtime here.

You are "tainting" the canvas by loading from a cross origins domain. Check out this MDN article:

https://developer.mozilla.org/en-US/docs/HTML/CORS_Enabled_Image

Want to center an image? Very easy, Bootstrap comes with two classes, .center-block and text-center.

Use the former in the case of your image being a BLOCK element, for example, adding img-responsive class to your img makes the img a block element. You should know this if you know how to navigate in the web console and see applied styles to an element.

Don't want to use a class? No problem, here is the CSS bootstrap uses. You can make a custom class or write a CSS rule for the element to match the Bootstrap class.

 // In case you're dealing with a block element apply this to the element itself 
.center-block {
   margin-left:auto;
   margin-right:auto;
   display:block;
}

// In case you're dealing with a inline element apply this to the parent 
.text-center {
   text-align:center
}

@Swapnil Godambe It works for me if JSON.stringfy is removed. That is:

$(jQuery.parseJSON(dataArray)).each(function() {  
    var ID = this.id;
    var TITLE = this.Title;
});

Simply return with the 'flag' that you want to be treated without using any additional user function. The Controller:

return \Redirect::back()->withSuccess( 'Message you want show in View' );

Notice that I used the 'Success' flag.

The View:

@if( Session::has( 'success' ))
     {{ Session::get( 'success' ) }}
@elseif( Session::has( 'warning' ))
     {{ Session::get( 'warning' ) }} <!-- here to 'withWarning()' -->
@endif

Yes, it really works!

use the "onmouseup" property with each option element. it's verbose, but should work. also, depending on what your function is actually doing, you could arrange things a little differently, assuming the number is important in the handler:

<select>
<option onmouseup="handler()" value="1">1</option>  //get selected element in handler
<option onmouseup="handler(2)" value="2">2</option>  //explicitly send the value as argument
<option onmouseup="handler(this.value)" value="3">3</option> //same as above, but using the element's value property and allowing for dynamic option value. you could also send "this.innerHTML" or "this.textContent" to the handler, making option value unnecessary
</select>

Simple first create a class

 public class ViewDialog {

        public void showDialog(Activity activity, String msg){
            final Dialog dialog = new Dialog(activity);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(false);
            dialog.setContentView(R.layout.custom_dialogbox_otp);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

            TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
            text.setText(msg);

            Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
            dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
                    dialog.dismiss();
                }
            });

            Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
            dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    dialog.cancel();

I'm able to run an SQL query by piping it to SQL*Plus:

If you are on macOS and are not using NVM, the simplest way is to run the installer that comes from node.js web site. It it clever enough to manage substitution of your current installation with the new one, even if it is an older one. At least this worked for me.

Sometimes when I wan to explore around in a particular method and summoning pdb is just too cumbersome, I would add:

import IPython; IPython.embed()

IPython.embed() starts an IPython shell which have access to the local variables from the point where you call it.

I had the same error

[Vue warn]: Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.

however, I totally forgot to run npm install && npm run dev to compiling the js files.

maybe this helps newbies like me.

The quickest way is to switch default branch from master to another and you can remove master branch from the web interface.

please escape your variables when outputting (urlencode).

and you can’t just print an array, you have to build your url using a loop in some way

$url = 'http://example.com/index.php?'
$first = true;
foreach($aValues as $key => $value) {
  if(!$first) $url .= '&amp';
  else $first = false;
  $url .= 'aValues['.urlencode($key).']='.urlencode($value);
}

electron FAQ answer :

http://electron.atom.io/docs/faq/

I can not use jQuery/RequireJS/Meteor/AngularJS in Electron.

Due to the Node.js integration of Electron, there are some extra symbols inserted into the DOM like module, exports, require. This causes problems for some libraries since they want to insert the symbols with the same names.

To solve this, you can turn off node integration in Electron:

// In the main process.

let win = new BrowserWindow({  
 webPreferences: {
 nodeIntegration: false   } });

But if you want to keep the abilities of using Node.js and Electron APIs, you have to rename the symbols in the page before including other libraries:

<head> 
<script> 
window.nodeRequire = require; 
delete window.require;
delete window.exports; delete window.module; 
</script> 
<script type="text/javascript" src="jquery.js"></script> 
</head>

The error crontab: temp file must be edited in place is because of the way vim treats backup files.

To use vim with cron, add the following lines in your .bash_profile
export EDITOR=vim
alias crontab="VIM_CRONTAB=true crontab"

Source the file:
source .bash_profile

And then in your .vimrc add:
if $VIM_CRONTAB == "true" set nobackup set nowritebackup endif

This will disable backups when using vim with cron. And you will be able to use crontab -e to add/edit cronjobs.

On successfully saving your cronjob, you will see the message:
crontab: installing new crontab

This is how I did it on Windows 7, after installing OpenSSL (link goes to the Win32 installer, choose the latest version and not the light version).

With this method you only need the .cer file downloaded from Apple.

c:\OpenSSL-Win32\bin\openssl.exe x509 -in aps_development.cer -inform DER -out developer_identity.pem -outform PEM

this will create a file which you will then need to add your private key too.

-----BEGIN PRIVATE KEY-----
MIIEuwIBADANBgkqhk....etc
MIIEuwIBADANBgkqhk....etc
MIIEuwIBADANBgkqhk....etc
MIIEuwIBADANBgkqhk....etc
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
AwIBAgwIBADAwIBADA....etc
AwIBAgwIBADAwIBADA....etc
AwIBAgwIBADAwIBADA....etc
-----END CERTIFICATE-----

That's it.

Better than all above is ever to use Standard C specification for struct initialization:

struct StructType structVar = {0};

Here are all bits zero (ever).

I may have missed something here, but why can't you just declare your string with the desired size? For example, in my VBA code I often use something like:

Dim AString As String * 1024

which provides for a 1k string. Obviously, you can use whatever declaration you like within the larger limits of Excel and available memory etc.

This may be a little inefficient in some cases, and you will probably wish to use Trim(AString) like constructs to obviate any superfluous trailing blanks. Still, it easily exceeds 256 chars.

To clarify the terminology right: arrays are fixed length structures (and the length of an existing cannot be altered) the expression add at the end is meaningless (by itself).

What you can do is create a new array one element larger and fill in the new element in the last slot:

public static int[] append(int[] array, int value) {
     int[] result = Arrays.copyOf(array, array.length + 1);
     result[result.length - 1] = value;
     return result;
}

This quickly gets inefficient, as each time append is called a new array is created and the old array contents is copied over.

One way to drastically reduce the overhead is to create a larger array and keep track of up to which index it is actually filled. Adding an element becomes as simple a filling the next index and incrementing the index. If the array fills up completely, a new array is created with more free space.

And guess what ArrayList does: exactly that. So when a dynamically sized array is needed, ArrayList is a good choice. Don't reinvent the wheel.

switch to the boto-* directory and type python setup.py install.

A more explicit option is to project collection to an IEnumerable of KeyValuePair and then convert it to a Dictionary.

Dictionary<int, string> dictionary = objects
    .Select(x=> new KeyValuePair<int, string>(x.Id, x.Name))
    .ToDictionary(x=>x.Key, x=>x.Value);

library(dplyr)
rename(data, de=de.y)

Another example with using Objective-C associated objects and computed properties for Swift 3 and Swift 4

import CoreLocation

extension CLLocation {

    private struct AssociatedKeys {
        static var originAddress = "originAddress"
        static var destinationAddress = "destinationAddress"
    }

    var originAddress: String? {
        get {
            return objc_getAssociatedObject(self, &AssociatedKeys.originAddress) as? String
        }
        set {
            if let newValue = newValue {
                objc_setAssociatedObject(
                    self,
                    &AssociatedKeys.originAddress,
                    newValue as NSString?,
                    .OBJC_ASSOCIATION_RETAIN_NONATOMIC
                )
            }
        }
    }

    var destinationAddress: String? {
        get {
            return objc_getAssociatedObject(self, &AssociatedKeys.destinationAddress) as? String
        }
        set {
            if let newValue = newValue {
                objc_setAssociatedObject(
                    self,
                    &AssociatedKeys.destinationAddress,
                    newValue as NSString?,
                    .OBJC_ASSOCIATION_RETAIN_NONATOMIC
                )
            }
        }
    }

Just to generate the java classes from wsdl to me the best tool is "cxf wsdl2java". Its pretty simple and easy to use. I have found some complexities with some data type in axis2. But unfortunately you can't use those client stub code in your android application because android environment doesn't allow the "java/javax" package name in compiling time unless you rename the package name.

And in the android.jar all the javax.* sources for web service consuming are not available. To resolve these I have developed this WS Client Generation Tool for android.

In background it uses "cxf wsdl2java" to generate the java client stub for android platform for you, And I have written some sources to consume the web service in a smarter way.

Just give the wsdl file location it will give you the sources and some library. you have to just put the sources and the libraries in your project. and you can just call it in some "method call fashion" just we do in our enterprise project, you don't need to know the namespace/soap action etc. For example, you have a service to login, what you need to do is :

LoginService service = new LoginService ( );
Login login = service.getLoginPort ( );
LoginServiceResponse resp = login.login ( "someUser", "somePass" );

And its fully open and free.

Creating a data.table with key=V1 automatically does this for you. Using Stephan's data foo

3:  1 392
4:  2  94
5:  3  49
6:  3  32
7:  4 459

$variable = array('this' => 1,
                    'that' => 1
                    'that' => 1,
                    'this_too' => 1,
                    'that_too' => 1,
                    'this_as_well' => 1,
                    'that_as_well' => 1,
                    'this_one_too' => 1,
                    'that_one_too' => 1,
                    'this_one_as_well' => 1,
                    'that_one_as_well' => 1);

foreach ($variable as $key => $value) {
    User::where($key, '=', $value);

If you want to clear all radio buttons in the DOM:

$('input[type=radio]').prop('checked',false);

If you are simply after a pretty solution and don't need to save a few nanoseconds, how about some LINQ sugar?

var input = "test1test2test3";
var replacements = new Dictionary<string, string> { { "1", "*" }, { "2", "_" }, { "3", "&" } };

var output = replacements.Aggregate(input, (current, replacement) => current.Replace(replacement.Key, replacement.Value));

I want to more fully address the issue of scroll duration, which, should you choose any earlier answer, will in fact will vary dramatically (and unacceptably) according to the amount of scrolling necessary to reach the target position from the current position .

To obtain a uniform scroll duration the velocity (pixels per millisecond) must account for the size of each individual item - and when the items are of non-standard dimension then a whole new level of complexity is added.

This may be why the RecyclerView developers deployed the too-hard basket for this vital aspect of smooth scrolling.

Assuming that you want a semi-uniform scroll duration, and that your list contains semi-uniform items then you will need something like this.

/** Smoothly scroll to specified position allowing for interval specification. <br>
 * Note crude deceleration towards end of scroll
 * @param rv        Your RecyclerView
 * @param toPos     Position to scroll to
 * @param duration  Approximate desired duration of scroll (ms)
 * @throws IllegalArgumentException */
private static void smoothScroll(RecyclerView rv, int toPos, int duration) throws IllegalArgumentException {
    int TARGET_SEEK_SCROLL_DISTANCE_PX = 10000;     // See androidx.recyclerview.widget.LinearSmoothScroller
    int itemHeight = rv.getChildAt(0).getHeight();  // Height of first visible view! NB: ViewGroup method!
    itemHeight = itemHeight + 33;                   // Example pixel Adjustment for decoration?
    int fvPos = ((LinearLayoutManager)rv.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
    int i = Math.abs((fvPos - toPos) * itemHeight);
    if (i == 0) { i = (int) Math.abs(rv.getChildAt(0).getY()); }
    final int totalPix = i;                         // Best guess: Total number of pixels to scroll
    RecyclerView.SmoothScroller smoothScroller = new LinearSmoothScroller(rv.getContext()) {
        @Override protected int getVerticalSnapPreference() {
            return LinearSmoothScroller.SNAP_TO_START;
        }
        @Override protected int calculateTimeForScrolling(int dx) {
            int ms = (int) ( duration * dx / (float)totalPix );
            // Now double the interval for the last fling.
            if (dx < TARGET_SEEK_SCROLL_DISTANCE_PX ) { ms = ms*2; } // Crude deceleration!
            //lg(format("For dx=%d we allot %dms", dx, ms));
            return ms;
        }
    };
    //lg(format("Total pixels from = %d to %d = %d [ itemHeight=%dpix ]", fvPos, toPos, totalPix, itemHeight));
    smoothScroller.setTargetPosition(toPos);
    rv.getLayoutManager().startSmoothScroll(smoothScroller);
}

PS: I curse the day I began indiscriminately converting ListView to RecyclerView.

This is a long post, but I was tired of all these examples that weren't working for me because they used Promise objects or an errant this that has a different meaning when you are using Reactjs. My implementation was using a DropZone with reactjs, and I got the bytes using a framework similar to what is posted at this following site, when nothing else above would work: https://www.mokuji.me/article/drop-upload-tutorial-1 . There were 2 keys, for me:

1. You have to get the bytes from the event object, using and during a FileReader's onload function.

2. I tried various combinations, but in the end, what worked was:

   const bytes = e.target.result.split('base64,')[1];

Where e is the event. React requires const, you could use var in plain Javascript. But that gave me the base64 encoded byte string.

So I'm just going to include the applicable lines for integrating this as if you were using React, because that's how I was building it, but try to also generalize this, and add comments where necessary, to make it applicable to a vanilla Javascript implementation - caveated that I did not use it like that in such a construct to test it.

These would be your bindings at the top, in your constructor, in a React framework (not relevant to a vanilla Javascript implementation):

this.uploadFile = this.uploadFile.bind(this);
this.processFile = this.processFile.bind(this);
this.errorHandler = this.errorHandler.bind(this);
this.progressHandler = this.progressHandler.bind(this);

And you'd have onDrop={this.uploadFile} in your DropZone element. If you were doing this without React, this is the equivalent of adding the onclick event handler you want to run when you click the "Upload File" button.

<button onclick="uploadFile(event);" value="Upload File" />

Then the function (applicable lines... I'll leave out my resetting my upload progress indicator, etc.):

uploadFile(event){
    // This is for React, only
    this.setState({
      files: event,
    });
    console.log('File count: ' + this.state.files.length);

    // You might check that the "event" has a file & assign it like this 
    // in vanilla Javascript:
    // var files = event.target.files;
    // if (!files && files.length > 0)
    //     files = (event.dataTransfer ? event.dataTransfer.files : 
    //            event.originalEvent.dataTransfer.files);

    // You cannot use "files" as a variable in React, however:
    const in_files = this.state.files;

    // iterate, if files length > 0
    if (in_files.length > 0) {
      for (let i = 0; i < in_files.length; i++) {
      // use this, instead, for vanilla JS:
      // for (var i = 0; i < files.length; i++) {
        const a = i + 1;
        console.log('in loop, pass: ' + a);
        const f = in_files[i];  // or just files[i] in vanilla JS

        const reader = new FileReader();
        reader.onerror = this.errorHandler;
        reader.onprogress = this.progressHandler;
        reader.onload = this.processFile(f);
        reader.readAsDataURL(f);
      }      
   }
}

There was this question on that syntax, for vanilla JS, on how to get that file object:

JavaScript/HTML5/jQuery Drag-And-Drop Upload - "Uncaught TypeError: Cannot read property 'files' of undefined"

Note that React's DropZone will already put the File object into this.state.files for you, as long as you add files: [], to your this.state = { .... } in your constructor. I added syntax from an answer on that post on how to get your File object. It should work, or there are other posts there that can help. But all that Q/A told me was how to get the File object, not the blob data, itself. And even if I did fileData = new Blob([files[0]]); like in sebu's answer, which didn't include var with it for some reason, it didn't tell me how to read that blob's contents, and how to do it without a Promise object. So that's where the FileReader came in, though I actually tried and found I couldn't use their readAsArrayBuffer to any avail.

You will have to have the other functions that go along with this construct - one to handle onerror, one for onprogress (both shown farther below), and then the main one, onload, that actually does the work once a method on reader is invoked in that last line. Basically you are passing your event.dataTransfer.files[0] straight into that onload function, from what I can tell.

So the onload method calls my processFile() function (applicable lines, only):

processFile(theFile) {
  return function(e) {
    const bytes = e.target.result.split('base64,')[1];
  }
}

And bytes should have the base64 bytes.

Additional functions:

errorHandler(e){
    switch (e.target.error.code) {
      case e.target.error.NOT_FOUND_ERR:
        alert('File not found.');
        break;
      case e.target.error.NOT_READABLE_ERR:
        alert('File is not readable.');
        break;
      case e.target.error.ABORT_ERR:
        break;    // no operation
      default:
        alert('An error occurred reading this file.');
        break;
    }
  }

progressHandler(e) {
    if (e.lengthComputable){
      const loaded = Math.round((e.loaded / e.total) * 100);
      let zeros = '';

      // Percent loaded in string
      if (loaded >= 0 && loaded < 10) {
        zeros = '00';
      }
      else if (loaded < 100) {
        zeros = '0';
      }

      // Display progress in 3-digits and increase bar length
      document.getElementById("progress").textContent = zeros + loaded.toString();
      document.getElementById("progressBar").style.width = loaded + '%';
    }
  }

And applicable progress indicator markup:

<table id="tblProgress">
  <tbody>
    <tr>
      <td><b><span id="progress">000</span>%</b> <span className="progressBar"><span id="progressBar" /></span></td>
    </tr>                    
  </tbody>
</table>

And CSS:

.progressBar {
  background-color: rgba(255, 255, 255, .1);
  width: 100%;
  height: 26px;
}
#progressBar {
  background-color: rgba(87, 184, 208, .5);
  content: '';
  width: 0;
  height: 26px;
}

EPILOGUE:

Inside processFile(), for some reason, I couldn't add bytes to a variable I carved out in this.state. So, instead, I set it directly to the variable, attachments, that was in my JSON object, RequestForm - the same object as my this.state was using. attachments is an array so I could push multiple files. It went like this:

  const fileArray = [];
  // Collect any existing attachments
  if (RequestForm.state.attachments.length > 0) {
    for (let i=0; i < RequestForm.state.attachments.length; i++) {
      fileArray.push(RequestForm.state.attachments[i]);
    }
  }
  // Add the new one to this.state
  fileArray.push(bytes);
  // Update the state
  RequestForm.setState({
    attachments: fileArray,
  });

Then, because this.state already contained RequestForm:

this.stores = [
  RequestForm,    
]

I could reference it as this.state.attachments from there on out. React feature that isn't applicable in vanilla JS. You could build a similar construct in plain JavaScript with a global variable, and push, accordingly, however, much easier:

var fileArray = new Array();  // place at the top, before any functions

// Within your processFile():
var newFileArray = [];
if (fileArray.length > 0) {
  for (var i=0; i < fileArray.length; i++) {
    newFileArray.push(fileArray[i]);
  }
}
// Add the new one
newFileArray.push(bytes);
// Now update the global variable
fileArray = newFileArray;

Then you always just reference fileArray, enumerate it for any file byte strings, e.g. var myBytes = fileArray[0]; for the first file.

You can clear your bash history like this:

history -cw

Do it in two steps.

rm -r bar/
cp -r foo/ bar/

This worked great for me. Don't forget to put a filler div in there where the navigation bar used to be, or else the content will jump every time it's fixed/unfixed.

function setSkrollr(){
    var objDistance = $navbar.offset().top;
    $(window).scroll(function() {
        var myDistance = $(window).scrollTop();
        if (myDistance > objDistance){
            $navbar.addClass('navbar-fixed-top');
        }
        if (objDistance > myDistance){
            $navbar.removeClass('navbar-fixed-top');
        }
    });
}

One option you have when you enter the terminal > Run > Debug > Edit Configurations

select the appropriate conda environmnent.. Also when you create a new project - it asks to configure this location.

If any of other solution doesn't fix it, try to override the styles to hide the sort togglers:

.sorting_asc:after, .sorting_desc:after {
  content: "";
}

It provides rolled-up data without rolling up

i.e. Suppose I want to return the relative position of sales region

Using PARTITION BY, I can return the sales amount for a given region and the MAX amount across all sales regions in the same row.

This does mean you will have repeating data, but it may suit the end consumer in the sense that data has been aggregated but no data has been lost - as would be the case with GROUP BY.

You can use ClientScript.RegisterStartUpScript to inject javascript into the page on Page_Load.

Here's a link to MSDN reference: http://msdn.microsoft.com/en-us/library/asz8zsxy.aspx

Here's the code in Page_Load:

  List<string> tempString = new List<string>();
  tempString.Add("Hello");
  tempString.Add("World");

  StringBuilder sb = new StringBuilder();
  sb.Append("<script>");
  sb.Append("var testArray = new Array;");
  foreach(string str in tempString)
  {
    sb.Append("testArray.push('" + str + "');");
  }
  sb.Append("</script>");

  ClientScript.RegisterStartupScript(this.GetType(), "TestArrayScript", sb.ToString());

Notes: Use StringBuilder to build the script string as it will probably be long.

And here's the Javascript that checks for the injected array "testArray" before you can work with it:

if (testArray)
{
  // do something with testArray
}

There's 2 problems here:

1. Some consider this intrusive for C# to inject Javascript

2. We'll have to declare the array at a global context

If you can't live with that, another way would be to have the C# code save the Array into View State, then have the JavaScript use PageMethods (or web services) to call back to the server to get that View State object as an array. But I think that may be overkill for something like this.

I came across this question as I was attempting to focus the ChromeVox screen reader to the top of the "screen" after navigating to a new screen in a React single page app. Basically trying to emulate what would happen if this page was loaded by following a link to a new server-rendered web page.

This solution doesn't require any listeners, it uses withRouter() and the componentDidUpdate() lifecycle method to trigger a click to focus ChromeVox on the desired element when navigating to a new url path.

Implementation

I created a "Screen" component which is wrapped around the react-router switch tag which contains all the apps screens.

<Screen>
  <Switch>
    ... add <Route> for each screen here...
  </Switch>
</Screen>

Screen.tsx Component

Note: This component uses React + TypeScript

import React from 'react'
import { RouteComponentProps, withRouter } from 'react-router'

class Screen extends React.Component<RouteComponentProps> {
  public screen = React.createRef<HTMLDivElement>()
  public componentDidUpdate = (prevProps: RouteComponentProps) => {
    if (this.props.location.pathname !== prevProps.location.pathname) {
      // Hack: setTimeout delays click until end of current
      // event loop to ensure new screen has mounted.
      window.setTimeout(() => {
        this.screen.current!.click()
      }, 0)
    }
  }
  public render() {
    return <div ref={this.screen}>{this.props.children}</div>
  }
}

export default withRouter(Screen)

I had tried using focus() instead of click(), but click causes ChromeVox to stop reading whatever it is currently reading and start again where I tell it to start.

Advanced note: In this solution, the navigation <nav> which inside the Screen component and rendered after the <main> content is visually positioned above the main using css order: -1;. So in pseudo code:

<Screen style={{ display: 'flex' }}>
  <main>
  <nav style={{ order: -1 }}>
<Screen>

If you have any thoughts, comments, or tips about this solution, please add a comment.

You are accessing the list elements and then using them to attempt to index your list. This is not a good idea. You already have an answer showing how you could use indexing to get your sum list, but another option would be to zip the list with a slice of itself such that you can sum the pairs.

b = [i + j for i, j in zip(a, a[1:])]

None of the above solutions are going to work.

Try this:

function filter_html($value){
    $value = mb_convert_encoding($value, 'ISO-8859-1', 'UTF-8');
    return $value;
}

Using json, you can subclass JSONEncoder and override the default() method to provide your own custom serializers:

import json
import datetime

class DateTimeJSONEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, datetime.datetime):
            return obj.isoformat()
        else:
            return super(DateTimeJSONEncoder, self).default(obj)

Then, you can call it like this:

>>> DateTimeJSONEncoder().encode([datetime.datetime.now()])
'["2010-06-15T14:42:28"]'

Python lists were not made to operate on the beginning of the list and are very ineffective at this operation.

While you can write

mylist = [1, 2 ,3 ,4]
mylist.pop(0)

It's very inefficient.

If you only want to delete items from your list, you can do this with del:

del mylist[:n]

Which is also really fast:

In [34]: %%timeit
help=range(10000)
while help:
    del help[:1000]
   ....:
10000 loops, best of 3: 161 µs per loop

If you need to obtain elements from the beginning of the list, you should use collections.deque by Raymond Hettinger and its popleft() method.

from collections import deque

deque(['f', 'g', 'h', 'i', 'j'])

>>> d.pop()                          # return and remove the rightmost item
'j'
>>> d.popleft()                      # return and remove the leftmost item
'f'

A comparison:

list + pop(0)

In [30]: %%timeit
   ....: help=range(10000)
   ....: while help:
   ....:     help.pop(0)
   ....:
100 loops, best of 3: 17.9 ms per loop

deque + popleft()

In [33]: %%timeit
help=deque(range(10000))
while help:
    help.popleft()
   ....:
1000 loops, best of 3: 812 µs per loop

The only workable solution is to restore the .bak file. The contents and the structure of those files are not documented and therefore, there's really no way (other than an awful hack) to get this to work - definitely not worth your time and the effort!

The only tool I'm aware of that can make sense of .bak files without restoring them is Red-Gate SQL Compare Professional (and the accompanying SQL Data Compare) which allow you to compare your database structure against the contents of a .bak file. Red-Gate tools are absolutely marvelous - highly recommended and well worth every penny they cost!

And I just checked their web site - it does seem that you can indeed restore a single table from out of a .bak file with SQL Compare Pro ! :-)

As for current Chrome version (56) you can't remove it yet. Solution provided in other posts leads to overflowing some part of the video.

I've found another solution - you can make the preceding button to overlap the download button and simply cover it, by using this technique:

video::-webkit-media-controls-fullscreen-button {
   margin-right: -48px;
   z-index: 10;
   position: relative;
   background: #fafafa;
   background-image: url(https://image.flaticon.com/icons/svg/151/151926.svg);
   background-size: 35%;
   background-position: 50% 50%;
   background-repeat: no-repeat;
}

Example: https://jsfiddle.net/dk4q6hh2/

PS You might want to customise the icon, since it's for example only.

Here is my ES3 commented solution (gory details after the code):

function object_equals( x, y ) {
  if ( x === y ) return true;
    // if both x and y are null or undefined and exactly the same

  if ( ! ( x instanceof Object ) || ! ( y instanceof Object ) ) return false;
    // if they are not strictly equal, they both need to be Objects

  if ( x.constructor !== y.constructor ) return false;
    // they must have the exact same prototype chain, the closest we can do is
    // test there constructor.

  for ( var p in x ) {
    if ( ! x.hasOwnProperty( p ) ) continue;
      // other properties were tested using x.constructor === y.constructor

    if ( ! y.hasOwnProperty( p ) ) return false;
      // allows to compare x[ p ] and y[ p ] when set to undefined

    if ( x[ p ] === y[ p ] ) continue;
      // if they have the same strict value or identity then they are equal

    if ( typeof( x[ p ] ) !== "object" ) return false;
      // Numbers, Strings, Functions, Booleans must be strictly equal

    if ( ! object_equals( x[ p ],  y[ p ] ) ) return false;
      // Objects and Arrays must be tested recursively
  }

  for ( p in y )
    if ( y.hasOwnProperty( p ) && ! x.hasOwnProperty( p ) )
      return false;
        // allows x[ p ] to be set to undefined

  return true;
}

In developing this solution, I took a particular look at corner cases, efficiency, yet trying to yield a simple solution that works, hopefully with some elegance. JavaScript allows both null and undefined properties and objects have prototypes chains that can lead to very different behaviors if not checked.

First I have chosen to not extend Object.prototype, mostly because null could not be one of the objects of the comparison and that I believe that null should be a valid object to compare with another. There are also other legitimate concerns noted by others regarding the extension of Object.prototype regarding possible side effects on other's code.

Special care must taken to deal the possibility that JavaScript allows object properties can be set to undefined, i.e. there exists properties which values are set to undefined. The above solution verifies that both objects have the same properties set to undefined to report equality. This can only be accomplished by checking the existence of properties using Object.hasOwnProperty( property_name ). Also note that JSON.stringify() removes properties that are set to undefined, and that therefore comparisons using this form will ignore properties set to the value undefined.

Functions should be considered equal only if they share the same reference, not just the same code, because this would not take into account these functions prototype. So comparing the code string does not work to guaranty that they have the same prototype object.

The two objects should have the same prototype chain, not just the same properties. This can only be tested cross-browser by comparing the constructor of both objects for strict equality. ECMAScript 5 would allow to test their actual prototype using Object.getPrototypeOf(). Some web browsers also offer a __proto__ property that does the same thing. A possible improvement of the above code would allow to use one of these methods whenever available.

The use of strict comparisons is paramount here because 2 should not be considered equal to "2.0000", nor false should be considered equal to null, undefined, or 0.

Efficiency considerations lead me to compare for equality of properties as soon as possible. Then, only if that failed, look for the typeof these properties. The speed boost could be significant on large objects with lots of scalar properties.

No more that two loops are required, the first to check properties from the left object, the second to check properties from the right and verify only existence (not value), to catch these properties which are defined with the undefined value.

Overall this code handles most corner cases in only 16 lines of code (without comments).

Update (8/13/2015). I have implemented a better version, as the function value_equals() that is faster, handles properly corner cases such as NaN and 0 different than -0, optionally enforcing objects' properties order and testing for cyclic references, backed by more than 100 automated tests as part of the Toubkal project test suite.

       String youtubeLink = "http://youtube.com/watch?v=xxxx";

    YouTubeUriExtractor ytEx = new YouTubeUriExtractor(this) {
        @Override
        public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
            if (ytFiles != null) {
                int itag = 22;
// Here you can get download url

In selection formula try this

Date(Year({datetimefield}), Month({datetimefield}), Day({datetimefield}))

I found that while adding

app.use(bodyParser.json());
app.use(bodyParser.urlencoded({
  extended: true
}));

helps, sometimes it's a matter of your querying that determines how express handles it.

For instance, it could be that your parameters are passed in the URL rather than in the body

In such a case, you need to capture both the body and url parameters and use whichever is available (with preference for the body parameters in the case below)

app.route('/echo')
    .all((req,res)=>{
        let pars = (Object.keys(req.body).length > 0)?req.body:req.query;
        res.send(pars);
    });

Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'. Next the unit of the current zoom is calculated, it could be one of:

• second
• minute
• hour
• day
• week
• month
• year

This unit is then used find a format for the axis labels. The default patterns are:

second: '%H:%M:%S',
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'

If you want the day to be part of the "hour"-level labels you should change the dateTimeLabelFormats option for that level include %d or %e. These are the available patters:

• %a: Short weekday, like 'Mon'.
• %A: Long weekday, like 'Monday'.
• %d: Two digit day of the month, 01 to 31.
• %e: Day of the month, 1 through 31.
• %b: Short month, like 'Jan'.
• %B: Long month, like 'January'.
• %m: Two digit month number, 01 through 12.
• %y: Two digits year, like 09 for 2009.
• %Y: Four digits year, like 2009.
• %H: Two digits hours in 24h format, 00 through 23.
• %I: Two digits hours in 12h format, 00 through 11.
• %l (Lower case L): Hours in 12h format, 1 through 11.
• %M: Two digits minutes, 00 through 59.
• %p: Upper case AM or PM.
• %P: Lower case AM or PM.
• %S: Two digits seconds, 00 through 59

http://api.highcharts.com/highcharts#xAxis.dateTimeLabelFormats

To answer a modulo x % y, you ask two questions:

A- How many times y goes in x without remainder ? For 2%4 that's 0.

B- How much do you need to add to get from that back to x ? To get from 0 back to 2 you'll need 2-0, i.e. 2.

These can be summed up in one question like so: How much will you need to add to the integer-ish result of the division of x by y, to get back at x?

By integer-ish it is meant only whole numbers and not fractions whatsoever are of interest.

A fractional division remainder (e.g. .283849) is not of interest in modulo because modulo only deals with integer numbers.

Example: Display different output depending on whether the user is logged in or not.

<?php

if ( is_user_logged_in() ) {
    echo 'Welcome, registered user!';
} else {
    echo 'Welcome, visitor!';
}

?>

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" }));

Just as a note you can also use this for iPads:

activityViewController.popoverPresentationController?.sourceView = sender

So the popover pops from the sender (the button in that case).

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

/**
 * @param num The number to round
 * @param precision The number of decimal places to preserve
 */
function roundUp(num, precision) {
  precision = Math.pow(10, precision)
  return Math.ceil(num * precision) / precision
}

roundUp(192.168, 1) //=> 192.2

You will need to store the image in the database as a BLOB.

you will want to create a column called PHOTO in your table and set it as a mediumblob.

Then you will want to get it from the form like so:

    $data = file_get_contents($_FILES['photo']['tmp_name']);

and then set the column to the value in $data.

Of course, this is bad practice and you would probably want to store the file on the system with a name that corresponds to the users account.

Solution for ajax pages that continuously load data. The previews methods stated do not work. What we can do instead is grab the page dom and hash it and compare old and new hash values together over a delta time.

import time
from selenium import webdriver

def page_has_loaded(driver, sleep_time = 2):
    '''
    Waits for page to completely load by comparing current page hash values.
    '''

    def get_page_hash(driver):
        '''
        Returns html dom hash
        '''
        # can find element by either 'html' tag or by the html 'root' id
        dom = driver.find_element_by_tag_name('html').get_attribute('innerHTML')
        # dom = driver.find_element_by_id('root').get_attribute('innerHTML')
        dom_hash = hash(dom.encode('utf-8'))
        return dom_hash

    page_hash = 'empty'
    page_hash_new = ''
    
    # comparing old and new page DOM hash together to verify the page is fully loaded
    while page_hash != page_hash_new: 
        page_hash = get_page_hash(driver)
        time.sleep(sleep_time)
        page_hash_new = get_page_hash(driver)
        print('<page_has_loaded> - page not loaded')

    print('<page_has_loaded> - page loaded: {}'.format(driver.current_url))

Using XAML:

If you know the other assembly structure and want the resources in c# code, then use below code:

 ResourceDictionary dictionary = new ResourceDictionary();
 dictionary.Source = new Uri("pack://application:,,,/WpfControlLibrary1;Component/RD1.xaml", UriKind.Absolute);
 foreach (var item in dictionary.Values)
 {
    //operations
 }

Output: If we want to use ResourceDictionary RD1.xaml of Project WpfControlLibrary1 into StackOverflowApp project.

Structure of Projects:

Resource Dictionary:

Code Output:

PS: All ResourceDictionary Files should have Build Action as 'Resource' or 'Page'.

Using C#:

If anyone wants the solution in purely c# code then see my this solution.

The method you're looking for is charAt. Here's an example:

String text = "foo";
char charAtZero = text.charAt(0);
System.out.println(charAtZero); // Prints f

For more information, see the Java documentation on String.charAt. If you want another simple tutorial, this one or this one.

If you don't want the result as a char data type, but rather as a string, you would use the Character.toString method:

String text = "foo";
String letter = Character.toString(text.charAt(0));
System.out.println(letter); // Prints f

If you want more information on the Character class and the toString method, I pulled my info from the documentation on Character.toString.

The dataset that I used had a lot of quote marks (") used extraneous of the formatting. I was able to fix the error by including this parameter for read_csv():

quoting=3 # 3 correlates to csv.QUOTE_NONE for pandas

I added "devenv.exe" as an exclusion to Windows Defender. This solved my problem completely. People can try this as their first try.

You can cast the columns if the types are different (datetime and timestamp or str) and use to_datetime :

df.loc[:,'Date'] = pd.to_datetime(df.Date.astype(str)+' '+df.Time.astype(str))

Result :

0   2013-01-06 23:00:00
1   2013-02-06 01:00:00
2   2013-02-06 21:00:00

Best,

For changing particular single column font size use following statement

DataGridView.Columns[1].DefaultCellStyle.Font = new Font("Verdana", 16, FontStyle.Bold);

php artisan dump-autoload was deprecated on Laravel 5, so you need to use composer dump-autoload

timer.scheduleAtFixedRate( new Task(), 1000,3000); 

You can redirect the output to /dev/null. For more info regarding /dev/null read this link.

You can hide the output of a comand in the following ways :

echo -n "Installing nano ......"; yum install nano > /dev/null; echo " done."; 

Redirect the standard output to /dev/null, but not the standard error. This will show the errors occurring during the installation, for example if yum cannot find a package.

echo -n "Installing nano ......"; yum install nano &> /dev/null; echo " done.";

While this code will not show anything in the terminal since both standard error and standard output are redirected and thus nullified to /dev/null.

You will have to make a call to the YouTube data API's video resource after you make the search call. You can put up to 50 video IDs in a search, so you won't have to call it for each element.

https://developers.google.com/youtube/v3/docs/videos/list

You'll want to set part=contentDetails, because the duration is there.

For example, the following call:

https://www.googleapis.com/youtube/v3/videos?id=9bZkp7q19f0&part=contentDetails&key={YOUR_API_KEY}

Gives this result:

{
 "kind": "youtube#videoListResponse",
 "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/ny1S4th-ku477VARrY_U4tIqcTw\"",
 "items": [
  {

   "id": "9bZkp7q19f0",
   "kind": "youtube#video",
   "etag": "\"XlbeM5oNbUofJuiuGi6IkumnZR8/HN8ILnw-DBXyCcTsc7JG0z51BGg\"",
   "contentDetails": {
    "duration": "PT4M13S",
    "dimension": "2d",
    "definition": "hd",
    "caption": "false",
    "licensedContent": true,
    "regionRestriction": {
     "blocked": [
      "DE"
     ]
    }
   }
  }
 ]
}

The time is formatted as an ISO 8601 string. PT stands for Time Duration, 4M is 4 minutes, and 13S is 13 seconds.

I had a similar problem. The problem was that I incorrectly wrote the properties of the model in the attributes of the view:

<TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@{ferm.coin.value}"/> 

This part was wrong:

@{ferm.coin.value}

When I wrote the correct property, the error was resolved.

Conditionally perform a command several times.

• syntax-FOR-Files

  FOR %%parameter IN (set) DO command 
  

• syntax-FOR-Files-Rooted at Path

  FOR /R [[drive:]path] %%parameter IN (set) DO command 
  

• syntax-FOR-Folders

  FOR /D %%parameter IN (folder_set) DO command 
  

• syntax-FOR-List of numbers

  FOR /L %%parameter IN (start,step,end) DO command 
  

• syntax-FOR-File contents

  FOR /F ["options"] %%parameter IN (filenameset) DO command 
  

  or

  FOR /F ["options"] %%parameter IN ("Text string to process") DO command
  

• syntax-FOR-Command Results

  FOR /F ["options"] %%parameter IN ('command to process') DO command
  

It

• Take a set of data
• Make a FOR Parameter %%G equal to some part of that data
• Perform a command (optionally using the parameter as part of the command).
• --> Repeat for each item of data

If you are using the FOR command at the command line rather than in a batch program, use just one percent sign: %G instead of %%G.

FOR Parameters

• The first parameter has to be defined using a single character, for example the letter G.

• FOR %%G IN ...

  In each iteration of a FOR loop, the IN ( ....) clause is evaluated and %%G set to a different value

  If this clause results in a single value then %%G is set equal to that value and the command is performed.

  If the clause results in a multiple values then extra parameters are implicitly defined to hold each. These are automatically assigned in alphabetical order %%H %%I %%J ...(implicit parameter definition)

  If the parameter refers to a file, then enhanced variable reference can be used to extract the filename/path/date/size.

  You can of course pick any letter of the alphabet other than %%G. but it is a good choice because it does not conflict with any of the pathname format letters (a, d, f, n, p, s, t, x) and provides the longest run of non-conflicting letters for use as implicit parameters.

In case anyone else is running in to the same problem, the only solution I could find that satisfied me was to have the canvas cover everything and then to raise the Z-index of all clickable elements. You can't draw on them, but at least they are clickable...

keyCodes are different from the ASCII values. For a complete keyCode reference, see http://unixpapa.com/js/key.html

For example, Numpad numbers have keyCodes 96 - 105, which corresponds to the beginning of lowercase alphabet in ASCII. This could lead to problems in validating numeric input.

Since you don't explicitly invoke a parent constructor as part of your child class constructor, there is an implicit call to a parameterless parent constructor inserted. That constructor does not exist, and so you get that error.

To correct the situation, you need to add an explicit call:

public Child(int i) : base(i)
{
    Console.WriteLine("child");
}

Or, you can just add a parameterless parent constructor:

protected Parent() { } 

I would add this to the LI's CSS

.list-item
{
    float: left;
    clear: left;
}

Currently there is still no native solution in Javascript for this behavior. Tagged templates are something related, but don't solve it.

Here there is a refactor of alex's solution with an object for replacements.

The solution uses arrow functions and a similar syntax for the placeholders as the native Javascript interpolation in template literals ({} instead of %%). Also there is no need to include delimiters (%) in the names of the replacements.

There are two flavors (three with the update): descriptive, reduced, elegant reduced with groups.

Descriptive solution:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '26',
};

const string = stringWithPlaceholders.replace(
  /{\w+}/g,
  placeholderWithDelimiters => {
    const placeholderWithoutDelimiters = placeholderWithDelimiters.substring(
      1,
      placeholderWithDelimiters.length - 1,
    );
    const stringReplacement = replacements[placeholderWithoutDelimiters] || placeholderWithDelimiters;
    return stringReplacement;
  },
);

console.log(string);

Reduced solution:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '26',
};

const string = stringWithPlaceholders.replace(/{\w+}/g, placeholder =>
  replacements[placeholder.substring(1, placeholder.length - 1)] || placeholder
);

console.log(string);

UPDATE 2020-12-10

Elegant reduced solution with groups, as suggested by @Kade in the comments:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '26',
};

const string = stringWithPlaceholders.replace(
  /{(\w+)}/g, 
  (placeholderWithDelimiters, placeholderWithoutDelimiters) =>
    replacements[placeholderWithoutDelimiters] || placeholderWithDelimiters
);

console.log(string);

UPDATE 2021-01-21

Support empty string as a replacement, as suggested by @Jesper in the comments:

const stringWithPlaceholders = 'My Name is {name} and my age is {age}.';

const replacements = {
  name: 'Mike',
  age: '',
};

const string = stringWithPlaceholders.replace(
  /{(\w+)}/g, 
  (placeholderWithDelimiters, placeholderWithoutDelimiters) =>
  replacements.hasOwnProperty(placeholderWithoutDelimiters) ? 
    replacements[placeholderWithoutDelimiters] : placeholderWithDelimiters
);

console.log(string);

We should always modularise our code and I've written the same check it below... We first check the directory, if the directory is absent we create the directory.

$boolDirPresents = $this->CheckDir($DirectoryName);

if (!$boolDirPresents) {
        $boolCreateDirectory = $this->CreateDirectory($DirectoryName);
        if ($boolCreateDirectory) {
        echo "Created successfully";
      }
  }

function CheckDir($DirName) {
    if (file_exists($DirName)) {
        echo "Dir Exists<br>";
        return true;
    } else {
        echo "Dir Not Absent<br>";
        return false;
    }
}

function CreateDirectory($DirName) {
    if (mkdir($DirName, 0777)) {
        return true;
    } else {
        return false;
    }
}

Execute the command in this format:

ALTER [ COLUMN ] column { SET | DROP } NOT NULL

Nesting (and) closures

Using closures for maintaining the scope of variables (in our case, the success callback function parameters) is the natural JavaScript solution. With promises, we can arbitrarily nest and flatten .then() callbacks - they are semantically equivalent, except for the scope of the inner one.

function getExample() {
    return promiseA(…).then(function(resultA) {
        // some processing
        return promiseB(…).then(function(resultB) {
            // more processing
            return // something using both resultA and resultB;
        });
    });
}

Of course, this is building an indentation pyramid. If indentation is getting too large, you still can apply the old tools to counter the pyramid of doom: modularize, use extra named functions, and flatten the promise chain as soon as you don't need a variable any more.
In theory, you can always avoid more than two levels of nesting (by making all closures explicit), in practise use as many as are reasonable.

function getExample() {
    // preprocessing
    return promiseA(…).then(makeAhandler(…));
}
function makeAhandler(…)
    return function(resultA) {
        // some processing
        return promiseB(…).then(makeBhandler(resultA, …));
    };
}
function makeBhandler(resultA, …) {
    return function(resultB) {
        // more processing
        return // anything that uses the variables in scope
    };
}

You can also use helper functions for this kind of partial application, like _.partial from Underscore/lodash or the native .bind() method, to further decrease indentation:

function getExample() {
    // preprocessing
    return promiseA(…).then(handlerA);
}
function handlerA(resultA) {
    // some processing
    return promiseB(…).then(handlerB.bind(null, resultA));
}
function handlerB(resultA, resultB) {
    // more processing
    return // anything that uses resultA and resultB
}

For WHM and cPanel, some versions need to explicty set mysqli to build.

Using WHM, under CENTOS 6.9 xen pv [dc] v68.0.27, one needed to rebuild Apache/PHP by looking at all options and select mysqli to build. The default was to build the deprecated mysql. Now the depreciation messages are gone and one is ready for future MySQL upgrades.

Click with the right mouse button on the file in your Google Drive. Choose the option to get a link which can be shared from the menu. You will see the file id now. Don't forget to undo the share.

I had the same problem.

• Accidentally amended the last commit that was already pushed
• Done a lot of changes locally, committed some five times
• Tried to push, got an error, panicked, merged remote, got a lot of not-my-files, pushed, failed, etc.

As a Git-newbie, I thought it was complete FUBAR.

Solution: Somewhat like @bara suggested + created a local backup branch

# Rewind to commit just before the pushed-and-amended one.
# Replace <hash> with the needed hash.
# --soft means: leave all the changes there, so nothing is lost.
git reset --soft <hash>

# Create new branch, just for a backup, still having all changes in it.
# The branch was feature/1234, new one - feature/1234-gone-bad
git checkout -b feature/1234-gone-bad

# Commit all the changes (all the mess) not to lose it & not to carry around
git commit -a -m "feature/1234 backup"

# Switch back to the original branch
git checkout feature/1234

# Pull the from remote (named 'origin'), thus 'repairing' our main problem
git pull origin/feature/1234

# Now you have a clean-and-non-diverged branch and a backup of the local changes.
# Check the needed files from the backup branch
git checkout feature/1234-gone-bad -- the/path/to/file.php

Maybe it's not a fast and clean solution, and I lost my history (1 commit instead of 5), but it saved a day's work.

var startTime = new TimeSpan(6, 0, 0); // 6:00 AM
var endTime = new TimeSpan(5, 30, 0); // 5:30 AM 
var hours24 = new TimeSpan(24, 0, 0);
var difference = endTime.Subtract(startTime); // (-00:30:00)
difference = (difference.Duration() != difference) ? hours24.Subtract(difference.Duration()) : difference; // (23:30:00)

can also add difference between the dates if we compare two different dates

new TimeSpan(24 * days, 0, 0)

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

You need to change div into p. Technically innerHTML means it is inside the <??? id=""></???> part.

Change:

<div id="hello"></div>

into

<p id="hello"></p>

Doing:

document.getElementById('hello').innerHTML = 'hi';

will turn

<div id="hello"></div> into this <div id="hello">hi</div>

which actually does not make sense.

You can also try to change:

document.getElementById('hello').innerHTML = 'hi';

into this

document.getElementById('hello').innerHTML='<p> hi </p> ';

to make it work.

You have to actually call some method to create the directories. Just creating a file object will not create the corresponding file or directory on the file system.

You can use File#mkdirs() method to create the directory: -

theFile.mkdirs();

Difference between File#mkdir() and File#mkdirs() is that, the later will create any intermediate directory if it does not exist.

One part of @gaurav solution worked for jQuery 2.1.3 and JQuery UI 1.10.2 with multiple sliders. My project is using four range sliders to filter data with this filter.js plugin. Other solutions were resetting the slider handles back to their starting end points just fine, but apparently they were not firing an event that filter.js understood. So here's how I looped through the sliders:

$("yourSliderSelection").each (function () {
    var hs = $(this); 
    var options = $(this).slider('option');

    //reset the ui
    $(this).slider( 'values', [ options.min, options.max ] ); 

    //refresh/trigger event so that filter.js can reset handling the data
    hs.slider('option', 'slide').call(
        hs, 
        null, 
        {
            handle: $('.ui-slider-handle', hs),
            values: [options.min, options.max]
        }
    );

});

The hs.slider() code resets the data, but not the UI in my scenario. Hope this helps others.

I improved the tütü response to properly disable EditText and RadioButton componentes. Besides, I'm sharing a way that I found to change the view visibility and add transparency in the disabled views.

private static void disableEnableControls(ViewGroup view, boolean enable){
    for (int i = 0; i < view.getChildCount(); i++) {
        View child = view.getChildAt(i);
        child.setEnabled(enable);
        if (child instanceof ViewGroup){
            disableEnableControls((ViewGroup)child, enable);
        }
        else if (child instanceof EditText) {
            EditText editText = (EditText) child;
            editText.setEnabled(enable);
            editText.setFocusable(enable);
            editText.setFocusableInTouchMode(enable);
        }
        else if (child instanceof RadioButton) {
            RadioButton radioButton = (RadioButton) child;
            radioButton.setEnabled(enable);
            radioButton.setFocusable(enable);
            radioButton.setFocusableInTouchMode(enable);
        }
    }
}

public static void setLayoutEnabled(ViewGroup view, boolean enable) {
    disableEnableControls(view, enable);
    view.setEnabled(enable);
    view.setAlpha(enable? 1f: 0.3f);
}

public static void setLayoutEnabled(ViewGroup view, boolean enable, boolean visibility) {
    disableEnableControls(view, enable);
    view.setEnabled(enable);
    view.setAlpha(enable? 1f: 0.3f);
    view.setVisibility(visibility? View.VISIBLE: View.GONE);
}

Here the output

To be able to inspect any element do the following. This should work even if it's hard to duplicate the hover state:

• Run the following javascript in the console. This will break into the debugger in 5 seconds.

  setTimeout(function(){debugger;}, 5000)

• Go show your element (by hovering or however) and wait until Chrome breaks into the Debugger.

• Now click on the Elements tab in the Chrome Inspector, and you can look for your element there.
• You may also be able to click on the Find Element icon (looks like a magnifying glass) and Chrome will let you go and inspect and find your element on the page by right clicking on it, then choosing Inspect Element

Note that this approach is a slight variation to this other great answer on this page.

A little late but I did run across this thread when trying out solutions for myself. Assuming you're using modern browsers nowadays, I came up with a solution using CSS calc() to help guarantee widths met up.

Note that the result of dereferencing an std::map::iterator is an std::pair. The values of first and second are not functions, they are variables.

Change:

iter->first()

to

iter->first

Ditto with iter->second.

well it depends if all you want is to position a div and then nothing else, you don't need to use java script for that. You can achieve this by CSS only. What matters is relative to what container you want to position your div, if you want to position it relative to document body then your div must be positioned absolute and its container must not be positioned relatively or absolutely, in that case your div will be positioned relative to the container.

Otherwise with Jquery if you want to position an element relative to document you can use offset() method.

$(".mydiv").offset({ top: 10, left: 30 });

if relative to offset parent position the parent relative or absolute. then use following...

var pos = $('.parent').offset();
var top = pos.top + 'no of pixel you want to give the mydiv from top relative to parent';
var left = pos.left + 'no of pixel you want to give the mydiv from left relative to parent';

$('.mydiv').css({
  position:'absolute',
  top:top,
  left:left
});

If the pop-up's document is from a different domain, this is simply not possible.

Update April 2015: I was wrong about this: if you own both domains, you can use window.postMessage and the message event in pretty much all browsers that are relevant today.

If not, there's still no way you'll be able to make this work cross-browser without some help from the document being loaded into the pop-up. You need to be able to detect a change in the pop-up that occurs once it has loaded, which could be a variable that JavaScript in the pop-up page sets when it handles its own load event, or if you have some control of it you could add a call to a function in the opener.

Try to use the fleqn document class option.

\documentclass[fleqn]{article}

(See also http://en.wikibooks.org/wiki/LaTeX/Basics for a list of other options.)

For the instance of

render :json => @projects, :include => :tasks

You are stating that you want to render @projects as JSON, and include the association tasks on the Project model in the exported data.

For the instance of

render :json => @projects, :callback => 'updateRecordDisplay'

You are stating that you want to render @projects as JSON, and wrap that data in a javascript call that will render somewhat like:

updateRecordDisplay({'projects' => []})

This allows the data to be sent to the parent window and bypass cross-site forgery issues.

Solution for me (Android Studio) :

1) Use shortcut Ctrl+Shift+Alt+S or File -> Project Structure

2) and increase the level of SDK "Compile SDK Version".

Just use Python's standard string formatting methods:

>>> "{0:.2}".format(1.234232)
'1.2'
>>> "{0:.3}".format(1.234232)
'1.23'

If you are using a Python version under 2.6, use

>>> "%f" % 1.32423
'1.324230'
>>> "%.2f" % 1.32423
'1.32'
>>> "%d" % 1.32423
'1'

You have to specify the projectBaseDir if the module name doesn't match you module directory.

Since both your module are located in ".", you can simply add the following to your sonar-project properties:

module1.sonar.projectBaseDir=.
module2.sonar.projectBaseDir=.

Sonar will handle your modules as components of the project:

EDIT

If both of your modules are located in the same source directory, define the same source folder for both and exclude the unwanted packages with sonar.exclusions:

module1.sonar.sources=src/main/java
module1.sonar.exclusions=app2code/**/*

module2.sonar.sources=src/main/java
module2.sonar.exclusions=app1code/**/*

This is a response I got from their Premium Services

Hello,

This is actually a issue with the way SSL validates names containing a period, '.', > character. We've documented this behavior here:

http://docs.amazonwebservices.com/AmazonS3/latest/dev/BucketRestrictions.html

The only straight-forward fix for this is to use a bucket name that does not contain that character. You might instead use a bucket named 'furniture-retailcatalog-us'. This would allow you use HTTPS with

https://furniture-retailcatalog-us.s3.amazonaws.com/

You could, of course, put a CNAME DNS record to make that more friendly. For example,

images-furniture.retailcatalog.us IN CNAME furniture-retailcatalog-us.s3.amazonaws.com.

Hope that helps. Let us know if you have any other questions.

Amazon Web Services

Unfortunately your "friendly" CNAME will cause host name mismatch when validating the certificate, therefore you cannot really use it for a secure connection. A big missing feature of S3 is accepting custom certificates for your domains.

UPDATE 10/2/2012

From @mpoisot:

The link Amazon provided no longer says anything about https. I poked around in the S3 docs and finally found a small note about it on the Virtual Hosting page: http://docs.amazonwebservices.com/AmazonS3/latest/dev/VirtualHosting.html

UPDATE 6/17/2013

From @Joseph Lust:

Just got it! Check it out and sign up for an invite: http://aws.amazon.com/cloudfront/custom-ssl-domains

for django help

CORS_EXPOSE_HEADERS = [
        'your header'
    ]

In addition to MR Chandru"s answer above, do these steps after configuring XAMPP:

• open the directory where XAMPP is installed. By default it's installed at C:\xampp
• Create Shortcut to the file xampp-control.exe, the XAMPP Control Panel
• Paste it in

C:\Users\User-Name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

or

C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp

The XAMPP Control Panel should now auto-start whenever you reboot Windows.

Other than foreground/background term. Another way to hide running window is via vbscript, if is is still available in your system.

DIM objShell
set objShell=wscript.createObject("wscript.shell")
iReturn=objShell.Run("yourcommand.exe", 0, TRUE)

name it as sth.vbs and call it from bat, put in sheduled task, etc. PersonallyI'll disable vbs with no haste at any Windows system I manage :)

If you are using JQuery dataTable so you need to just add "bFilter":true. This will display default search box outside table and its works dynamically..as per expected

$("#archivedAssignments").dataTable({
                "sPaginationType": "full_numbers",
                "bFilter":true,
                "sPageFirst": false,
                "sPageLast": false,
                "oLanguage": {
                "oPaginate": {
                    "sPrevious": "<< previous",
                    "sNext" : "Next >>",
                    "sFirst": "<<",
                    "sLast": ">>"
                    }
                },
            "bJQueryUI": false,
            "bLengthChange": false,
            "bInfo":false,
            "bSortable":true
        });    

if(isset($variable)){
    $isTouch = $variable;
}

OR

if(!isset($variable)){
    $isTouch = "";// 
}

in the first Activity:

Intent i=new Intent(getApplicationContext,secondActivity.class);

i.putExtra("key",value);

startActivity(i);

and in the SecondActivity:

String value=getIntent.getStringExtra("Key");

I do below and check if id exist and execute function if exist.

var divIDVar = $('#divID').length;
if (divIDVar === 0){ 
    console.log('No DIV Exist'); 
} else{  
    FNCsomefunction(); 
}   

package com.example.network.interceptors;

import androidx.annotation.NonNull;

import java.io.IOException;
import java.util.Map;

import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;

public class RequestHeadersNetworkInterceptor implements Interceptor {

    private final Map<String, String> headers;

    public RequestHeadersNetworkInterceptor(@NonNull Map<String, String> headers) {
        this.headers = headers;
    }

    @NonNull
    @Override
    public Response intercept(Chain chain) throws IOException {
        Request.Builder builder = chain.request().newBuilder();
        for (Map.Entry<String, String> header : headers.entrySet()) {
            if (header.getKey() == null || header.getKey().trim().isEmpty()) {
                continue;
            }
            if (header.getValue() == null || header.getValue().trim().isEmpty()) {
                builder.removeHeader(header.getKey());
            } else {
                builder.header(header.getKey(), header.getValue());
            }
        }
        return chain.proceed(builder.build());
    }

}

Example of usage:

httpClientBuilder.networkInterceptors().add(new RequestHeadersNetworkInterceptor(new HashMap<String, String>()
{
    {
        put("User-Agent", getUserAgent());
        put("Accept", "application/json");
    }
}));

Just add these to libraries to your project:

<link href="https://code.jquery.com/ui/1.10.2/themes/smoothness/jquery-ui.min.css" rel="stylesheet"></link>
<script src="https://code.jquery.com/ui/1.10.2/jquery-ui.min.js"></script>

Save and reload. You're good to go.

There is no Inbuilt support for SVG in Swift. So we need to use other libraries.

The simple SVG libraries in swift are :

1) SwiftSVG Library

It gives you more option to Import as UIView, CAShapeLayer, Path, etc

To modify your SVG Color and Import as UIImage you can use my extension codes for the library mentioned in below link,

Click here to know on using SwiftSVG library :
Using SwiftSVG to set SVG for Image

|OR|

2) SVGKit Library

2.1) Use pod to install :

pod 'SVGKit', :git => 'https://github.com/SVGKit/SVGKit.git', :branch => '2.x'

2.2) Add framework

Goto AppSettings
-> General Tab
-> Scroll down to Linked Frameworks and Libraries
-> Click on plus icon
-> Select SVG.framework

2.3) Add in Objective-C to Swift bridge file bridging-header.h :

#import <SVGKit/SVGKit.h>
#import <SVGKit/SVGKImage.h>

2.4) Create SvgImg Folder (for better organization) in Project and add SVG files inside it.

Note : Adding Inside Assets Folder won't work and SVGKit searches for file only in Project folders

2.5) Use in your Swift Code as below :

import SVGKit

and

let namSvgImgVar: SVGKImage = SVGKImage(named: "NamSvgImj")

Note : SVGKit Automatically apends extention ".svg" to the string you specify

let namSvgImgVyuVar = SVGKImageView(SVGKImage: namSvgImgVar)

let namImjVar: UIImage = namSvgImgVar.UIImage

There are many more options for you to init SVGKImage and SVGKImageView

There are also other classes u can explore

    SVGRect
    SVGCurve
    SVGPoint
    SVGAngle
    SVGColor
    SVGLength

    and etc ...

You can use block (/***/) or single line comment (//) for each line. You should use "#" in sh command.

Block comment

Use this nifty freeware utility:

CurrPorts is network monitoring software that displays the list of all currently opened TCP/IP and UDP ports on your local computer.

You can use rows and cols:

cout << "Width : " << src.cols << endl;
cout << "Height: " << src.rows << endl;

or size():

cout << "Width : " << src.size().width << endl;
cout << "Height: " << src.size().height << endl;

Shortest, but not supported by Internet Explorer 8 and earlier:

new Date().toJSON()

My solution was to patch the font file itself and fix its line height definitely. http://mbauman.net/geek/2009/03/15/minor-truetype-font-editing-on-a-mac/

I had to modify 'lineGap', 'ascender', 'descender' in the 'hhea' block (as in the blog example).

diff -y --suppress-common-lines file1 file2

First of all connect your phone and computer to common wifi.

Then, open command prompt using run as administrator

Give ipconfig command

Which shows wireless lan ip

Use ip:port of your server to access in phone

Add <b> tag

<p> <b> I am in Bold </b></p>

I think this is exactly what you were looking for

http://today.java.net/pub/a/today/2007/06/26/generating-pdfs-with-flying-saucer-and-itext.html

http://code.google.com/p/flying-saucer

Flying Saucer's primary purpose is to render spec-compliant XHTML and CSS 2.1 to the screen as a Swing component. Though it was originally intended for embedding markup into desktop applications (things like the iTunes Music Store), Flying Saucer has been extended work with iText as well. This makes it very easy to render XHTML to PDFs, as well as to images and to the screen. Flying Saucer requires Java 1.4 or higher.

For List:

All SwiftUI's Lists are backed by a UITableViewin iOS. so you need to change the background color of the tableView. But since Color and UIColor values are slightly different, you can get rid of the UIColor.

struct ContentView : View {
    init(){
        UITableView.appearance().backgroundColor = .clear
    }
    
    var body: some View {
        List {
            Section(header: Text("First Section")) {
                Text("First Cell")
            }
            Section(header: Text("Second Section")) {
                Text("First Cell")
            }
        }
        .background(Color.yellow)
    }
}

Now you can use Any background (including all Colors) you want

Also First look at this result:

As you can see, you can set the color of each element in the View hierarchy like this:

struct ContentView: View {
    
    init(){
        UINavigationBar.appearance().backgroundColor = .green 
        //For other NavigationBar changes, look here:(https://stackoverflow.com/a/57509555/5623035)
    }

    var body: some View {
        ZStack {
            Color.yellow
            NavigationView {
                ZStack {
                    Color.blue
                    Text("Some text")
                }
            }.background(Color.red)
        }
    }
}

And the first one is window:

window.backgroundColor = .magenta

The very common issue is we can not remove the background color of SwiftUI's HostingViewController (yet), so we can't see some of the views like navigationView through the views hierarchy. You should wait for the API or try to fake those views (not recommended).

First of all, public static non-final fields are evil. Spring does not allow injecting to such fields for a reason.

Your workaround is valid, you don't even need getter/setter, private field is enough. On the other hand try this:

@Value("${my.name}")
public void setPrivateName(String privateName) {
    Sample.name = privateName;
}  

(works with @Autowired/@Resource). But to give you some constructive advice: Create a second class with private field and getter instead of public static field.

jsfiddle.

<div> 
    <img class="class" src="http://i0.kym-cdn.com/photos/images/original/000/051/726/17-i-lol.jpg?1318992465">
    </img>
    <span>
        Hello World!
    </span>
</div>

What about this? No absolute positioning on div, but instead on img and span.

One possible way is to use .map() method:

var all = $(".mbox").map(function() {
    return this.innerHTML;
}).get();

console.log(all.join());

N.B. Please don't use document.write. For testing purposes console.log is the best way to go.
