All you have to do is use the GetFocusedRowCellValue method of the gridView control and put it into the RowClick event.

For example:

private void gridView1_RowClick(object sender, DevExpress.XtraGrid.Views.Grid.RowClickEventArgs e)
{
    if (this.gvCodigoNombres.GetFocusedRowCellValue("EMP_dni") == null)
        return;
    MessageBox.Show(""+this.gvCodigoNombres.GetFocusedRowCellValue("EMP_dni").ToString());            
}

pip install numpy scipy scikit-learn

if you don't have pip, install it using

python get-pip.py

Download get-pip.py from the following link. or use curl to download it.

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

When you set up your validation, you should be saving the validator object. you can use this to validate individual fields.

<script type="text/javascript">
var _validator;
$(function () {    
     _validator = $("#form").validate();   
});

function doSomething() {    
     _validator.element($('#someElement'));
}
</script>

You need to use the scrollTop property.

document.getElementById('box').scrollTop

Read it and weep!

I figured it out. If you don't throw from the handler, the handler will just continue and so will the exception.

The magic happens when you throw you own exception and handle that.

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <tchar.h>

void SignalHandler(int signal)
{
    printf("Signal %d",signal);
    throw "!Access Violation!";
}

int main()
{
    typedef void (*SignalHandlerPointer)(int);

    SignalHandlerPointer previousHandler;
    previousHandler = signal(SIGSEGV , SignalHandler);
    try{
        *(int *) 0 = 0;// Baaaaaaad thing that should never be caught. You should write good code in the first place.
    }
    catch(char *e)
    {
        printf("Exception Caught: %s\n",e);
    }
    printf("Now we continue, unhindered, like the abomination never happened. (I am an EVIL genius)\n");
    printf("But please kids, DONT TRY THIS AT HOME ;)\n");

}

May this one help a little more

Let suppose if you want to make the bar button in a separate file(for modular approach) and want to give selector back to your viewcontroller, you can do like this :-

your Utility File

class GeneralUtility {

    class func customeNavigationBar(viewController: UIViewController,title:String){
        let add = UIBarButtonItem(title: "Play", style: .plain, target: viewController, action: #selector(SuperViewController.buttonClicked(sender:)));  
      viewController.navigationController?.navigationBar.topItem?.rightBarButtonItems = [add];
    }
}

Then make a SuperviewController class and define the same function on it.

class SuperViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
            // Do any additional setup after loading the view.
    }
    @objc func buttonClicked(sender: UIBarButtonItem) {

    }
}

and In our base viewController(which inherit your SuperviewController class) override the same function

import UIKit

class HomeViewController: SuperViewController {

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func viewWillAppear(_ animated: Bool) {
        GeneralUtility.customeNavigationBar(viewController: self,title:"Event");
    }

    @objc override func buttonClicked(sender: UIBarButtonItem) {
      print("button clicked")    
    } 
}

Now just inherit the SuperViewController in whichever class you want this barbutton.

Thanks for the read

I had a slightly different problem. The credential problem was for the underlying user running the application, not the user trying to login. One way to test this is to go to IIS Management -> Sites -> Your Site -> Basic Settings -> Test Settings.

My problem turned out to be Attribute Routing in WebAPI. I created a custom route, and it treated it like a GET instead of WebAPI discovering it was a POST

    [Route("")]
    [HttpPost] //I added this attribute explicitly, and it worked
    public void Post(ProductModel data)
    {
        ...
    }

I knew it had to be something silly (that consumes your entire day)

I've found a simple soluition for this by creating a base activity class , u must extend all your activity classes from this :

public class BaseActivity extends ActionBarActivity {

@Override
protected void onResume() {
    ApplicationStateChecker.view_resumed(this);
    super.onResume();
}

@Override
protected void onStop() {
    ApplicationStateChecker.view_stopped(this);
    super.onStop();

}

@Override
protected void onPause() {
    ApplicationStateChecker.view_paused(this);
    super.onPause();

}

}

ApplicationStateChecker class :

public class ApplicationStateChecker {

private  static final String _pause_string = "paused";
private  static final String _resume_string = "resumed";

private static String _view_lastState;
private static boolean _from_background = true;

public static void view_paused(Activity activity){
    _view_lastState = _pause_string;
}

public static void view_stopped(Activity activity){

    if (  _view_lastState.equals(_pause_string) ){
        //if stop called and last event was pause then app is brought to background
        _from_background = true;
    }  //if

}

public static void view_resumed(Activity activity){

    if (  _from_background ) {
       //Do your stuff here , app is brought to foreground 

    }  //if

    _from_background = false;
    _view_lastState = _resume_string;
}

A polyfill is a piece of code (or plugin) that provides the technology that you, the developer, expect the browser to provide natively.

In C, a string is actually stored as an array of characters, so the 'string pointer' is pointing to the first character. For instance,

char myString[] = "This is some text";

You can access any character as a simple char by using myString as an array, thus:

char myChar = myString[6];
printf("%c\n", myChar); // Prints s

Hope this helps! David

Nothing stops you from doing

moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

Check this example

var a, b, c;_x000D_
a = b = c = 10;_x000D_
console.log(a + b + c)

No, but you can in Scala! (And then compile that and run it using any Java implementation!!!!)

Now, if you want to do it the easy way in java, use the Apache commons-lang package. Assuming you're using maven, add this dependency to your pom.xml:

    <dependency>
        <groupId>commons-lang</groupId>
        <artifactId>commons-lang</artifactId>
        <version>2.4</version>
    </dependency>

And then use StringUtils.repeat as follows:

import org.apache.commons.lang.StringUtils
...
someNum = sumNum + StringUtils.repeat("0", 3);

I see this has been answered, but it seems like you could avoid all of this 'remapping' of the enter key by simply hooking your validation into the AcceptButton on a form. ie. you have 3 textboxes (txtA,txtB,txtC) and an 'OK' button set to be AcceptButton (and TabOrder set properly). So, if in txtA and you hit enter, if the data is invalid, your focus will stay in txtA, but if it is valid, assuming the other txts need input, validation will just put you into the next txt that needs valid input thus simulating TAB behaviour... once all txts have valid input, pressing enter will fire a succsessful validation and close form (or whatever...) Make sense?

If you are using Eclipse Neon, try this:

1) Add the maven plugin in the properties section of the POM:

<properties>
    <java.version>1.8</java.version>
    <maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>

2) Force update of project snapshot by right clicking on Project

Maven -> Update Project -> Select your Project -> Tick on the 'Force Update of Snapshots/Releases' option -> OK

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

Here you have few solutions ;)

As per bash - The Set Builtin manual, if -e/errexit is set, the shell exits immediately if a pipeline consisting of a single simple command, a list or a compound command returns a non-zero status.

By default, the exit status of a pipeline is the exit status of the last command in the pipeline, unless the pipefail option is enabled (it's disabled by default).

If so, the pipeline's return status of the last (rightmost) command to exit with a non-zero status, or zero if all commands exit successfully.

If you'd like to execute something on exit, try defining trap, for example:

trap onexit EXIT

where onexit is your function to do something on exit, like below which is printing the simple stack trace:

onexit(){ while caller $((n++)); do :; done; }

There is similar option -E/errtrace which would trap on ERR instead, e.g.:

trap onerr ERR

Examples

Zero status example:

$ true; echo $?
0

Non-zero status example:

$ false; echo $?
1

Negating status examples:

$ ! false; echo $?
0
$ false || true; echo $?
0

Test with pipefail being disabled:

$ bash -c 'set +o pipefail -e; true | true | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; false | false | true; echo success'; echo $?
success
0
$ bash -c 'set +o pipefail -e; true | true | false; echo success'; echo $?
1

Test with pipefail being enabled:

$ bash -c 'set -o pipefail -e; true | false | true; echo success'; echo $?
1

With

def person = new Person("Kumar", 12) 

you are defining a function/lazy variable which always returns a new Person instance with name "Kumar" and age 12. This is totally valid and the compiler has no reason to complain. Calling person.age will return the age of this newly created Person instance, which is always 12.

When writing

person.age = 45

you assign a new value to the age property in class Person, which is valid since age is declared as var. The compiler will complain if you try to reassign person with a new Person object like

person = new Person("Steve", 13)  // Error

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

I think this is enough to get you on a nice path:

Sub a()
  Dim btn As Button
  Application.ScreenUpdating = False
  ActiveSheet.Buttons.Delete
  Dim t As Range
  For i = 2 To 6 Step 2
    Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
    Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
    With btn
      .OnAction = "btnS"
      .Caption = "Btn " & i
      .Name = "Btn" & i
    End With
  Next i
  Application.ScreenUpdating = True
End Sub

Sub btnS()
 MsgBox Application.Caller
End Sub

It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.

A visual for those that benefit from it.

After right-clicking the project name ("test" in this example), select "Add framework support" and check the "Maven" option.

With 'Enter' is better use ReadLine() or Read(2), because key 'Enter' generate 2 symbols. If user enter any text next Pause() also wil be skipped even with Read(2). So ReadLine() is better:

Sub Pause()
    WScript.Echo ("Press Enter to continue")
    z = WScript.StdIn.ReadLine()
End Sub

From the C++ FAQ:

[15.1] Why should I use <iostream> instead of the traditional <cstdio>?

Increase type safety, reduce errors, allow extensibility, and provide inheritability.

printf() is arguably not broken, and scanf() is perhaps livable despite being error prone, however both are limited with respect to what C++ I/O can do. C++ I/O (using << and >>) is, relative to C (using printf() and scanf()):

• More type-safe: With <iostream>, the type of object being I/O'd is known statically by the compiler. In contrast, <cstdio> uses "%" fields to figure out the types dynamically.
• Less error prone: With <iostream>, there are no redundant "%" tokens that have to be consistent with the actual objects being I/O'd. Removing redundancy removes a class of errors.
• Extensible: The C++ <iostream> mechanism allows new user-defined types to be I/O'd without breaking existing code. Imagine the chaos if everyone was simultaneously adding new incompatible "%" fields to printf() and scanf()?!
• Inheritable: The C++ <iostream> mechanism is built from real classes such as std::ostream and std::istream. Unlike <cstdio>'s FILE*, these are real classes and hence inheritable. This means you can have other user-defined things that look and act like streams, yet that do whatever strange and wonderful things you want. You automatically get to use the zillions of lines of I/O code written by users you don't even know, and they don't need to know about your "extended stream" class.

On the other hand, printf is significantly faster, which may justify using it in preference to cout in very specific and limited cases. Always profile first. (See, for example, http://programming-designs.com/2009/02/c-speed-test-part-2-printf-vs-cout/)

This a variant of Igor Ostroumov's answer:

If you would like to use it as a default value for a parameter, you need to consider a second level call to 'caller':

function getFunctionsNameThatCalledThisFunction()
{
  return getFunctionsNameThatCalledThisFunction.caller.caller.name;
}

This would dynamically allow for a reusable implementation in multiple functions.

function getFunctionsNameThatCalledThisFunction()_x000D_
{_x000D_
  return getFunctionsNameThatCalledThisFunction.caller.caller.name;_x000D_
}_x000D_
_x000D_
function bar(myFunctionName = getFunctionsNameThatCalledThisFunction())_x000D_
{ _x000D_
  alert(myFunctionName);_x000D_
}_x000D_
_x000D_
// pops-up "foo"_x000D_
function foo()_x000D_
{_x000D_
  bar();_x000D_
}_x000D_
_x000D_
function crow()_x000D_
{_x000D_
  bar();_x000D_
}_x000D_
_x000D_
foo();_x000D_
crow();

If you want the file name too, here is that solution using the answer from F-3000 on another question:

function getCurrentFileName()
{
  let currentFilePath = document.scripts[document.scripts.length-1].src 
  let fileName = currentFilePath.split('/').pop() // formatted to the OP's preference

  return fileName 
}

function bar(fileName = getCurrentFileName(),  myFunctionName = getFunctionsNameThatCalledThisFunction())
{
  alert(fileName + ' : ' + myFunctionName);
}

// or even better: "myfile.js : foo"
function foo()
{
  bar();
}

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

For the ones using the web browser, you can do the following:

• Once in the master repository, click on Create new file.
• In the name of file box at the top, enter the name of your folder
• Use the / key after the name of the folder. Using this forward slash creates the folder
• You can see a new box appear next to the folder name wherein you can type the name of your file.
• In the Commit new file box at the bottom of the page, you can type the description for your file.
• Select the radio button Commit directly to the master branch.
• Click on the Commit new file button
• You will see the new directory will be created.

Unfortunatelly, Ajax events are poorly documented and I haven't found any comprehensive list. For example, User Guide v. 3.5 lists itemChange event for p:autoComplete, but forgets to mention change event.

If you want to find out which events are supported:

1. Download and unpack primefaces source jar
2. Find the JavaScript file, where your component is defined (for example, most form components such as SelectOneMenu are defined in forms.js)
3. Search for this.cfg.behaviors references

For example, this section is responsible for launching toggleSelect event in SelectCheckboxMenu component:

fireToggleSelectEvent: function(checked) {
    if(this.cfg.behaviors) {
        var toggleSelectBehavior = this.cfg.behaviors['toggleSelect'];

        if(toggleSelectBehavior) {
            var ext = {
                params: [{name: this.id + '_checked', value: checked}]
            }
        }

        toggleSelectBehavior.call(this, null, ext);
    }
},

Try this

<style>
@font-face {
        font-family: Roboto Bold Condensed;
        src: url(fonts/Roboto_Condensed/RobotoCondensed-Bold.ttf);
}
@font-face {
         font-family:Roboto Condensed;
        src: url(fonts/Roboto_Condensed/RobotoCondensed-Regular.tff);
}

div1{
    font-family:Roboto Bold Condensed;
}
div2{
    font-family:Roboto Condensed;
}
</style>
<div id='div1' >This is Sample text</div>
<div id='div2' >This is Sample text</div>

For Windows, apparently the JDK has to be under C:\Program Files.

This does not work:

C:\dev\Java\jdk1.8.0_191     

This works:

C:\Program Files\Java\jdk1.8.0_191     

(I'm using IntelliJ IDEA Ultimate 2018.2.4.)

See also: asciichart (implemented in Node.js, Python, Java, Go and Haskell)

To address this problem, I have used setx command which try to set user level variables.

I used below...

setx JAVA_HOME "C:\Program Files\Java\jdk1.8.0_92"

setx PATH %JAVA_HOME%\bin

NOTE: Windows try to append provided variable value to existing variable value. So no need to give extra %PATH%... something like %JAVA_HOME%\bin;%PATH%

The way you describe is the way I've always done it. Since it's totally generic, you can always break that functionality out into a mixin class and inherit it in classes where you want that functionality.

class CommonEqualityMixin(object):

    def __eq__(self, other):
        return (isinstance(other, self.__class__)
            and self.__dict__ == other.__dict__)

    def __ne__(self, other):
        return not self.__eq__(other)

class Foo(CommonEqualityMixin):

    def __init__(self, item):
        self.item = item

Use the below class to Generate a Salt first. Each user needs to have a different salt, we can save it in the database along with the other user properties. The rounds value decides the number of times the password will be hashed.

For more details: https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.rfc2898derivebytes.-ctor?view=netcore-3.1#System_Security_Cryptography_Rfc2898DeriveBytes__ctor_System_Byte___System_Byte___System_Int32_

public class HashSaltWithRounds
{
    int saltLength = 32;
    public byte[] GenerateSalt()
    {
        using (var randomNumberGenerator = new RNGCryptoServiceProvider())
        {
            var randomNumber = new byte[saltLength];
            randomNumberGenerator.GetBytes(randomNumber);
            return randomNumber;
        }
    }

    public string HashDataWithRounds(byte[] password, byte[] salt, int rounds)
    {
        using(var rfc2898= new Rfc2898DeriveBytes(password, salt, rounds))
        {
            return Convert.ToBase64String(rfc2898.GetBytes(32));
        }
    }
}

We can call it from a console application as follows. I have hashed the password twice using the same salt.

public class Program
{
    public static void Main(string[] args)
    {
        int numberOfIterations = 99;
        var hashFunction = new HashSaltWithRounds();

        string password = "Your Password Here";
        byte[] salt = hashFunction.GenerateSalt();

        var hashedPassword1 = hashFunction.HashDataWithRounds(Encoding.UTF8.GetBytes(password), salt, numberOfIterations);
        var hashedPassword2 = hashFunction.HashDataWithRounds(Encoding.UTF8.GetBytes(password), salt, numberOfIterations);

        Console.WriteLine($"hashedPassword1 :{hashedPassword1}");
        Console.WriteLine($"hashedPassword2 :{hashedPassword2}");
        Console.WriteLine(hashedPassword1.Equals(hashedPassword2));

        Console.ReadLine();

    }
}

this.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

this worked for me in case of Class Extends Frame

I had the same problem and for me it was because the vc2010 redist x86 was too recent.

Check your temp folder (C:\Users\\AppData\Local\Temp) for the most recent file named

Microsoft Visual C++ 2010 x64 Redistributable Setup_20110608_xxx.html ##

and check if you have the following error

Installation Blockers:

A newer version of Microsoft Visual C++ 2010 Redistributable has been detected on the machine.

Final Result: Installation failed with error code: (0x000013EC), "A StopBlock was hit or a System >Requirement was not met." (Elapsed time: 0 00:00:00).

then go to Control Panel>Program & Features and uninstall all the

Microsoft Visual C++ 2010 x86/x64 redistributable - 10.0.(number over 30319)

After successful installation of DXSDK, simply run Windows Update and it will update the redistributables back to the latest version.

As stated in one of the comments, this works for Mac (probably for Windows/Linux too):

I WANT TO CONNECT FROM A CONTAINER TO A SERVICE ON THE HOST

The host has a changing IP address (or none if you have no network access). We recommend that you connect to the special DNS name host.docker.internal which resolves to the internal IP address used by the host. This is for development purpose and will not work in a production environment outside of Docker Desktop for Mac.

You can also reach the gateway using gateway.docker.internal.

Quoted from https://docs.docker.com/docker-for-mac/networking/

This worked for me without using --net=host.

Unfortunately there's a simple answer to this question, and it's "No"

The best way to set/get the value of a textarea is the .val(), .value method.

.text() internally uses the .textContent (or .innerText for IE) method to get the contents of a <textarea>. The following test cases illustrate how text() and .val() relate to each other:

var t = '<textarea>';
console.log($(t).text('test').val());             // Prints test
console.log($(t).val('too').text('test').val());  // Prints too
console.log($(t).val('too').text());              // Prints nothing
console.log($(t).text('test').val('too').val());  // Prints too

console.log($(t).text('test').val('too').text()); // Prints test

The value property, used by .val() always shows the current visible value, whereas text()'s return value can be wrong.

Create a text node and append it to the button element:

var t = document.createTextNode("test content");
b.appendChild(t);

If you look at this url: http://java.sun.com/developer/technicalArticles/J2SE/Desktop/javadb/

this part of the schema may be what you are looking for.

 ID          INTEGER NOT NULL 
                PRIMARY KEY GENERATED ALWAYS AS IDENTITY 
                (START WITH 1, INCREMENT BY 1),

None of these solutions worked for me. I had a tangle of Nuget packages that couldn't update because of circular dependencies on each other.

I would up having to fix this the old-fashioned way. I created a new MVC/web api project and manually copied System.Web.Http and System.Web.Http.WebHost from the new project into the Nuget folders of the exisitng solution. From there I updated the references by, OMG, "browsing" and fixed the problem.

1. Right-click your Project.
2. Select Properties.
3. On the left-hand side click Libraries.
4. Under Compile tab - click Add Jar/Folder button.

Or

1. Expand your Project.
2. Right-click Libraries.
3. Select Add Jar/Folder.

I will correct usage for that method that @BullyWillPlaza suggested. Reason is that when I try to add add textArea to only contextMenu it's not visible, and if i add it to both to contextMenu and some panel it ecounters: Different parent double association if i try to switch to Design editor.

TexetObjcet.addMouseListener(new MouseAdapter() {
        @Override
        public void mouseClicked(MouseEvent e) {
            if (SwingUtilities.isRightMouseButton(e)){
                contextmenu.add(TexetObjcet);
                contextmenu.show(TexetObjcet, 0, 0);
            }
        }
    }); 

Make mouse listener like this for text object you need to have popup on. What this will do is when you right click on your text object it will then add that popup and display it. This way you don't encounter that error. Solution that @BullyWillPlaza made is very good, rich and fast to implement in your program so you should try it our see how you like it.

This quote is taken from; Version Control with Git

Git runs garbage collection automatically:

• If there are too many loose objects in the repository

• When a push to a remote repository happens

• After some commands that might introduce many loose objects

• When some commands such as git reflog expire explicitly request it

And finally, garbage collection occurs when you explicitly request it using the git gc command. But when should that be? There’s no solid answer to this question, but there is some good advice and best practice.

You should consider running git gc manually in a few situations:

• If you have just completed a git filter-branch . Recall that filter-branch rewrites many commits, introduces new ones, and leaves the old ones on a ref that should be removed when you are satisfied with the results. All those dead objects (that are no longer referenced since you just removed the one ref pointing to them) should be removed via garbage collection.

• After some commands that might introduce many loose objects. This might be a large rebase effort, for example.

And on the flip side, when should you be wary of garbage collection?

• If there are orphaned refs that you might want to recover

• In the context of git rerere and you do not need to save the resolutions forever

• In the context of only tags and branches being sufficient to cause Git to retain a commit permanently

• In the context of FETCH_HEAD retrievals (URL-direct retrievals via git fetch ) because they are immediately subject to garbage collection

I would use the following a ternary operator alternative to accomplish the truncation with ... as follow:

<div>{{ modal.title.length > 20 ? (modal.title | limitTo : 20) + '...' : modal.title }}</div>

If at all possible, its always a good idea to create your XML using the XML classes rather than string manipulation - one of the benefits being that the classes will automatically escape characters as needed.

It actually tells you what's wrong, but you ignored it because you didn't check the error returned from json.Marshal.

json: unsupported type: map[int]main.Foo

JSON spec doesn't support anything except strings for object keys, while javascript won't be fussy about it, it's still illegal.

You have two options:

1 Use map[string]Foo and convert the index to string (using fmt.Sprint for example):

datas := make(map[string]Foo, N)

for i := 0; i < 10; i++ {
    datas[fmt.Sprint(i)] = Foo{Number: 1, Title: "test"}
}
j, err := json.Marshal(datas)
fmt.Println(string(j), err)

2 Simply just use a slice (javascript array):

datas2 := make([]Foo, N)
for i := 0; i < 10; i++ {
    datas2[i] = Foo{Number: 1, Title: "test"}
}
j, err = json.Marshal(datas2)
fmt.Println(string(j), err)

Java IO using stream oriented APIs is performed using a buffer as temporary storage of data within user space. Data read from disk by DMA is first copied to buffers in kernel space, which is then transfer to buffer in user space. Hence there is overhead. Avoiding it can achieve considerable gain in performance.

We could skip this temporary buffer in user space, if there was a way directly to access the buffer in kernel space. Java NIO provides a way to do so.

ByteBuffer is among several buffers provided by Java NIO. Its just a container or holding tank to read data from or write data to. Above behavior is achieved by allocating a direct buffer using allocateDirect() API on Buffer.

Java Documentation of Byte Buffer has useful information.

I am supporting iOS 5, 6, & 7. My app is iPad only. I needed to use all of the following:

[[UIApplication sharedApplication] setStatusBarHidden:YES];

View Controller:

- (BOOL)prefersStatusBarHidden{ return YES; }

Info.plist

    <key>UIStatusBarHidden</key>
    <string>YES</string>

    <key>UIStatusBarHidden~ipad</key>
    <true/>

    <key>UIViewControllerBasedStatusBarAppearance</key>
    <string>NO</string>

You can do that only by the following 2 lines:

DataGridView1.DataSource=Nothing
DataGridView1.DataBind()

Not possible, but you should check to see if border-style values like inset, outset or some other, accomplished the effect you want.. (i doubt it though..)

CSS3 has the border-image properties, but i do not know about support from browsers yet (more info at http://www.css3.info/preview/border-image/)..

I did this and it works great

<?php if ( has_post_thumbnail() ) { ?>
<a href="<?php the_permalink(); ?>" title="<?php the_title_attribute(); ?>"><?php the_post_thumbnail(); ?></a>
<?php } ?>

If you want to get the price of all cars you have to iterate through the array list:

public static void processCars(ArrayList<Cars> cars) {
   for (Car c : cars) {
       System.out.println (c.getPrice());
   }
}

You can create a custom control that inherits from the Button class. This code will be more reusable, please look at the following blog post for more details: WPF - create custom button with image (ImageButton)

Isn't neither localStorage or httpOnly cookie acceptable? In regards to a compromised 3rd party library, the only solution I know of that will reduce / prevent sensitive information from being stolen would be enforced Subresource Integrity.

Subresource Integrity (SRI) is a security feature that enables browsers to verify that resources they fetch (for example, from a CDN) are delivered without unexpected manipulation. It works by allowing you to provide a cryptographic hash that a fetched resource must match.

As long as the compromised 3rd party library is active on your website, a keylogger can start collecting info like username, password, and whatever else you input into the site.

An httpOnly cookie will prevent access from another computer but will do nothing to prevent the hacker from manipulating the user's computer.

Two options: no JQuery required, or JQuery version

No JQuery (or anything else required)

var textArea = document.getElementById('myTextAreaId');
var lines = textArea.value.split('\n');    // lines is an array of strings

// Loop through all lines
for (var j = 0; j < lines.length; j++) {
  console.log('Line ' + j + ' is ' + lines[j])
}

JQuery version

var lines = $('#myTextAreaId').val().split('\n');   // lines is an array of strings

// Loop through all lines
for (var j = 0; j < lines.length; j++) {
  console.log('Line ' + j + ' is ' + lines[j])
}

Side note, if you prefer forEach a sample loop is

lines.forEach(function(line) {
  console.log('Line is ' + line)
})

After a lot of digging around I finally ended up downloading the source code of the recovery section of Android. Turns out you can actually send commands to the recovery.

 * The arguments which may be supplied in the recovery.command file:
 *   --send_intent=anystring - write the text out to recovery.intent
 *   --update_package=path - verify install an OTA package file
 *   --wipe_data - erase user data (and cache), then reboot
 *   --wipe_cache - wipe cache (but not user data), then reboot
 *   --set_encrypted_filesystem=on|off - enables / diasables encrypted fs

Those are the commands you can use according to the one I found but that might be different for modded files. So using adb you can do this:

adb shell
recovery --wipe_data

Using --wipe_data seemed to do what I was looking for which was handy although I have not fully tested this as of yet.

EDIT:

For anyone still using this topic, these commands may change based on which recovery you are using. If you are using Clockword recovery, these commands should still work. You can find other commands in /cache/recovery/command

For more information please see here: https://github.com/CyanogenMod/android_bootable_recovery/blob/cm-10.2/recovery.c

Bitcode (iOS, watchOS)

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Basically this concept is somewhat similar to java where byte code is run on different JVM's and in this case the bitcode is placed on iTune store and instead of giving the intermediate code to different platforms(devices) it provides the compiled code which don't need any virtual machine to run.

Thus we need to create the bitcode once and it will be available for existing or coming devices. It's the Apple's headache to compile an make it compatible with each platform they have.

Devs don't have to make changes and submit the app again to support new platforms.

Let's take the example of iPhone 5s when apple introduced x64 chip in it. Although x86 apps were totally compatible with x64 architecture but to fully utilise the x64 platform the developer has to change the architecture or some code. Once s/he's done the app is submitted to the app store for the review.

If this bitcode concept was launched earlier then we the developers doesn't have to make any changes to support the x64 bit architecture.

Use eq to get to specific element.

You should execute script for install docker and launch it from command line:

brew install --cask docker
sudo -H pip3 install --upgrade pip3
open -a Docker
docker-compose ... 

after that docker-compose should work

Quick solution without downloading anything is to use online editors that has "Magic Wand Tool".

& <-- verifies both operands
&& <-- stops evaluating if the first operand evaluates to false since the result will be false

(x != 0) & (1/x > 1) <-- this means evaluate (x != 0) then evaluate (1/x > 1) then do the &. the problem is that for x=0 this will throw an exception.

(x != 0) && (1/x > 1) <-- this means evaluate (x != 0) and only if this is true then evaluate (1/x > 1) so if you have x=0 then this is perfectly safe and won't throw any exception if (x != 0) evaluates to false the whole thing directly evaluates to false without evaluating the (1/x > 1).

EDIT:

exprA | exprB <-- this means evaluate exprA then evaluate exprB then do the |.

exprA || exprB <-- this means evaluate exprA and only if this is false then evaluate exprB and do the ||.

None of the answers here quite hit the nail on the head.

How to store a datetime in MySQL with timezone info

Use two columns: DATETIME, and a VARCHAR to hold the time zone information, which may be in several forms:

A timezone or location such as America/New_York is the highest data fidelity.

A timezone abbreviation such as PST is the next highest fidelity.

A time offset such as -2:00 is the smallest amount of data in this regard.

Some key points:

• Avoid TIMESTAMP because it's limited to the year 2038, and MySQL relates it to the server timezone, which is probably undesired.
• A time offset should not be stored naively in an INT field, because there are half-hour and quarter-hour offsets.

If it's important for your use case to have MySQL compare or sort these dates chronologically, DATETIME has a problem:

'2009-11-10 11:00:00 -0500' is before '2009-11-10 10:00:00 -0700' in terms of "instant in time", but they would sort the other way when inserted into a DATETIME.

You can do your own conversion to UTC. In the above example, you would then have
'2009-11-10 16:00:00' and '2009-11-10 17:00:00' respectively, which would sort correctly. When retrieving the data, you would then use the timezone info to revert it to its original form.

One recommendation which I quite like is to have three columns:

• local_time DATETIME
• utc_time DATETIME
• time_zone VARCHAR(X) where X is appropriate for what kind of data you're storing there. (I would choose 64 characters for timezone/location.)

An advantage to the 3-column approach is that it's explicit: with a single DATETIME column, you can't tell at a glance if it's been converted to UTC before insertion.

Regarding the descent of accuracy through timezone/abbreviation/offset:

• If you have the user's timezone/location such as America/Juneau, you can know accurately what the wall clock time is for them at any point in the past or future (barring changes to the way Daylight Savings is handled in that location). The start/end points of DST, and whether it's used at all, are dependent upon location, so this is the only reliable way.
• If you have a timezone abbreviation such as MST, (Mountain Standard Time) or a plain offset such as -0700, you will be unable to predict a wall clock time in the past or future. For example, in the United States, Colorado and Arizona both use MST, but Arizona doesn't observe DST. So if the user uploads his cat photo at 14:00 -0700 during the winter months, was he in Arizona or California? If you added six months exactly to that date, would it be 14:00 or 13:00 for the user?

These things are important to consider when your application has time, dates, or scheduling as core function.

even this will work:

<div class="container">
            <div class="row">
                <div class="col-4 col-sm-4 col-md-6 order-1">
                    1
                </div>
                <div class="col-4 col-sm-4  col-md-6 order-3">
                    2
                </div>
                <div class="col-4 col-sm-4  col-md-12 order-2">
                    3
                </div>
            </div>
          </div>

No, the Compare function will return either 1, 0, or -1. 0 when the two values are equal, -1 and 1 mean less than and greater than, I believe in that order, but I often mix them up.

Just created this:

Storage.setObj('users.albums.sexPistols',"blah");
Storage.setObj('users.albums.sexPistols',{ sid : "My Way", nancy : "Bitch" });
Storage.setObj('users.albums.sexPistols.sid',"Other songs");

//Getters
Storage.getObj('users');
Storage.getObj('users.albums');
Storage.getObj('users.albums.sexPistols');
Storage.getObj('users.albums.sexPistols.sid');
Storage.getObj('users.albums.sexPistols.nancy');

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

Take a look at your code :

 getUsers(): Observable<User[]> {
        return Observable.create(observer => {
            this.http.get('http://users.org').map(response => response.json();
        })
    }

and code from https://angular.io/docs/ts/latest/tutorial/toh-pt6.html (BTW. really good tutorial, you should check it out)

 getHeroes(): Promise<Hero[]> {
    return this.http.get(this.heroesUrl)
               .toPromise()
               .then(response => response.json().data as Hero[])
               .catch(this.handleError);
  }

The HttpService inside Angular2 already returns an observable, sou don't need to wrap another Observable around like you did here:

   return Observable.create(observer => {
        this.http.get('http://users.org').map(response => response.json()

Try to follow the guide in link that I provided. You should be just fine when you study it carefully.

---EDIT----

First of all WHERE you log the this.users variable? JavaScript isn't working that way. Your variable is undefined and it's fine, becuase of the code execution order!

Try to do it like this:

  getUsers(): void {
        this.userService.getUsers()
            .then(users => {
               this.users = users
               console.log('this.users=' + this.users);
            });


    }

See where the console.log(...) is!

Try to resign from toPromise() it's seems to be just for ppl with no RxJs background.

Catch another link: https://scotch.io/tutorials/angular-2-http-requests-with-observables Build your service once again with RxJs observables.

The following is a nice generic alternative to valueOf()

public static RandomEnum getEnum(String value) {
  for (RandomEnum re : RandomEnum.values()) {
    if (re.description.compareTo(value) == 0) {
      return re;
    }
  }
  throw new IllegalArgumentException("Invalid RandomEnum value: " + value);
}

You could use SET ANSI_NULLS in order to specify the behavior of the Equals (=) and Not Equal To (<>) comparison operators when they are used with null values.

Simply replace message parameter passed in clientSocket.sendto(message,(serverName, serverPort)) to clientSocket.sendto(message.encode(),(serverName, serverPort)). Then you would successfully run in in python3

If you set { responseType: 'blob' }, no need to create Blob on your own. You can simply create url based with response content:

$http({
    url: "...",
    method: "POST",
    responseType: "blob"
}).then(function(response) {
    var fileURL = URL.createObjectURL(response.data);
    window.open(fileURL);
});

If you need to parse ASN.1 objects in script, there's a library for that: https://github.com/lapo-luchini/asn1js

For doing the math, I found jsbn convenient: http://www-cs-students.stanford.edu/~tjw/jsbn/

Walking the ASN.1 structure and extracting the exp/mod/subject/etc. is up to you -- I never got that far!

To change the directory for target dll/exe, use this in your pro file:

CONFIG(debug, debug|release) {
    DESTDIR = build/debug
} else {
    DESTDIR = build/release
}

You might also want to change directories for other build targets like object files and moc files (check qmake variable reference for details or qmake CONFIG() function reference).

db:create - Creates the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases.

db:create:all - Creates the database for all environments.

db:drop - Drops the database for the current RAILS_ENV environment. If RAILS_ENV is not specified it defaults to the development and test databases.

db:drop:all - Drops the database for all environments.

db:migrate - Runs migrations for the current environment that have not run yet. By default it will run migrations only in the development environment.

db:migrate:redo - Runs db:migrate:down and db:migrate:up or db:migrate:rollback and db:migrate:up depending on the specified migration.

db:migrate:up - Runs the up for the given migration VERSION.

db:migrate:down - Runs the down for the given migration VERSION.

db:migrate:status - Displays the current migration status.

db:migrate:rollback - Rolls back the last migration.

db:version - Prints the current schema version.

db:forward - Pushes the schema to the next version.

db:seed - Runs the db/seeds.rb file.

db:schema:load Recreates the database from the schema.rb file. Deletes existing data.

db:schema:dump Dumps the current environment’s schema to db/schema.rb.

db:structure:load - Recreates the database from the structure.sql file.

db:structure:dump - Dumps the current environment’s schema to db/structure.sql. (You can specify another file with SCHEMA=db/my_structure.sql)

db:setup Runs db:create, db:schema:load and db:seed.

db:reset Runs db:drop and db:setup. db:migrate:reset - Runs db:drop, db:create and db:migrate.

db:test:prepare - Check for pending migrations and load the test schema. (If you run rake without any arguments it will do this by default.)

db:test:clone - Recreate the test database from the current environment’s database schema.

db:test:clone_structure - Similar to db:test:clone, but it will ensure that your test database has the same structure, including charsets and collations, as your current environment’s database.

db:environment:set - Set the current RAILS_ENV environment in the ar_internal_metadata table. (Used as part of the protected environment check.)

db:check_protected_environments - Checks if a destructive action can be performed in the current RAILS_ENV environment. Used internally when running a destructive action such as db:drop or db:schema:load.

Have you checked this http://docs.python.org/2/install/ ?

1. First you have to install the module

   $ pip install requests

2. Then, before using it you must import it from your program.

   from requests import requests

   Note that your modules must be in the same directory.

3. Then you can use it.

   For this part you have to check for the documentation.

You need to enable 'INDENT' and set the indent amount for the transformer:

t.setOutputProperty(OutputKeys.INDENT, "yes");
t.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");

Very often you have no option to setup the sending server so what I did I changed the XMLHttpRequest.open call in my javascript to a local get-file.php file where I have the following code in it:

<?php_x000D_
  $file = file($_GET['url']);_x000D_
  echo implode('', $file);_x000D_
?>

javascript is doing this:

var xhttp = new XMLHttpRequest();_x000D_
xhttp.onreadystatechange = function() {_x000D_
  if (this.readyState == 4 && this.status == 200) {_x000D_
    // File content is now in the this.responseText_x000D_
  }_x000D_
};_x000D_
xhttp.open("GET", "get-file.php?url=http://site/file", true);_x000D_
xhttp.send();

In my case this solved the restriction/situation just perfectly. No need to hack Firefox or servers. Just load your javascript/html file with that small php file into the server and you're done.

The order of initialization doesn’t matter. All fields are initialized in the order of their definition in their class/struct. But if the order in initialization list is different gcc/g++ generate this warning. Only change the initialization order to avoid this warning. But you can't define field using in initialization before its construct. It will be a runtime error. So you change the order of definition. Be careful and keep attention!

You could declare a variable as a temporary table like this:

declare @myList table (Id int)

Which means you can use the insert statement to populate it with values:

insert into @myList values (1), (2), (5), (7), (10)

Then your select statement can use either the in statement:

select * from DBTable
where id in (select Id from @myList)

Or you could join to the temporary table like this:

select *
from DBTable d
join @myList t on t.Id = d.Id

And if you do something like this a lot then you could consider defining a user-defined table type so you could then declare your variable like this:

declare @myList dbo.MyTableType

Iterate over the grep results with a while/read loop. Like:

grep pattern filename.txt | while read -r line ; do
    echo "Matched Line:  $line"
    # your code goes here
done

I don't recommend storing passwords in a script, but this is a way to what you indicate:

use 5.010;
my %user_table = ( tom => '123!', frank => '321!' );

say ( $user_table{ $name } eq $password ? 'You have gained access.'
    :                                     'Access denied!'
    );

Any time you want to enforce an association like this, it's a good idea to think of a table, and the most common form of table in Perl is the hash.

This is an old question and you might have got the answer already.

My plnkr explains on my approach to accomplish selecting a default dropdown value. Basically, I have a service which would return the dropdown values [hard coded to test]. I was not able to select the value by default and almost spend a day and finally figured out that I should have set $scope.proofGroupId = "47"; instead of $scope.proofGroupId = 47; in the script.js file. It was my bad and I did not notice that I was setting an integer 47 instead of the string "47". I retained the plnkr as it is just in case if some one would like to see. Hopefully, this would help some one.

$(".radioValue").css({"background-color":"-webkit-linear-gradient(#e9e9e9,rgba(255, 255, 255, 0.43137254901960786),#e9e9e9)","color":"#454545", "padding": "8px"});

This function will tell you if your string contains ONLY the characters 0123456789.

private bool IsInt(string sVal)
{
    foreach (char c in sVal)
    {
         int iN = (int)c;
         if ((iN > 57) || (iN < 48))
            return false;
    }
    return true;
}

This is different from int.TryParse() which will tell you if your string COULD BE an integer.
eg. " 123\r\n" will return TRUE from int.TryParse() but FALSE from the above function.

...Just depends on the question you need to answer.

Try this example and you will understand also what is the difference between Associative Array and Object in JavaScript.

Associative Array

var a = new Array(1,2,3); 
a['key'] = 'experiment';
Array.isArray(a);

returns true

Keep in mind that a.length will be undefined, because length is treated as a key, you should use Object.keys(a).length to get the length of an Associative Array.

Object

var a = {1:1, 2:2, 3:3,'key':'experiment'}; 
Array.isArray(a)

returns false

JSON returns an Object ... could return an Associative Array ... but it is not like that

This is how I calculated the real dimensions for the first letter (you can change the method header to suit your needs, i.e. instead of char[] use String):

private void calculateTextSize(char[] text, PointF outSize) {
    // use measureText to calculate width
    float width = mPaint.measureText(text, 0, 1);

    // use height from getTextBounds()
    Rect textBounds = new Rect();
    mPaint.getTextBounds(text, 0, 1, textBounds);
    float height = textBounds.height();
    outSize.x = width;
    outSize.y = height;
}

Note that I'm using TextPaint instead of the original Paint class.

Note

This is excerpted from my "What is the Strict Aliasing Rule and Why do we care?" write-up.

What is strict aliasing?

In C and C++ aliasing has to do with what expression types we are allowed to access stored values through. In both C and C++ the standard specifies which expression types are allowed to alias which types. The compiler and optimizer are allowed to assume we follow the aliasing rules strictly, hence the term strict aliasing rule. If we attempt to access a value using a type not allowed it is classified as undefined behavior(UB). Once we have undefined behavior all bets are off, the results of our program are no longer reliable.

Unfortunately with strict aliasing violations, we will often obtain the results we expect, leaving the possibility the a future version of a compiler with a new optimization will break code we thought was valid. This is undesirable and it is a worthwhile goal to understand the strict aliasing rules and how to avoid violating them.

To understand more about why we care, we will discuss issues that come up when violating strict aliasing rules, type punning since common techniques used in type punning often violate strict aliasing rules and how to type pun correctly.

Preliminary examples

Let's look at some examples, then we can talk about exactly what the standard(s) say, examine some further examples and then see how to avoid strict aliasing and catch violations we missed. Here is an example that should not be surprising (live example):

int x = 10;
int *ip = &x;

std::cout << *ip << "\n";
*ip = 12;
std::cout << x << "\n";

We have a int* pointing to memory occupied by an int and this is a valid aliasing. The optimizer must assume that assignments through ip could update the value occupied by x.

The next example shows aliasing that leads to undefined behavior (live example):

int foo( float *f, int *i ) { 
    *i = 1;               
    *f = 0.f;            

   return *i;
}

int main() {
    int x = 0;

    std::cout << x << "\n";   // Expect 0
    x = foo(reinterpret_cast<float*>(&x), &x);
    std::cout << x << "\n";   // Expect 0?
}

In the function foo we take an int* and a float*, in this example we call foo and set both parameters to point to the same memory location which in this example contains an int. Note, the reinterpret_cast is telling the compiler to treat the the expression as if it had the type specificed by its template parameter. In this case we are telling it to treat the expression &x as if it had type float*. We may naively expect the result of the second cout to be 0 but with optimization enabled using -O2 both gcc and clang produce the following result:

0
1

Which may not be expected but is perfectly valid since we have invoked undefined behavior. A float can not validly alias an int object. Therefore the optimizer can assume the constant 1 stored when dereferencing i will be the return value since a store through f could not validly affect an int object. Plugging the code in Compiler Explorer shows this is exactly what is happening(live example):

foo(float*, int*): # @foo(float*, int*)
mov dword ptr [rsi], 1  
mov dword ptr [rdi], 0
mov eax, 1                       
ret

The optimizer using Type-Based Alias Analysis (TBAA) assumes 1 will be returned and directly moves the constant value into register eax which carries the return value. TBAA uses the languages rules about what types are allowed to alias to optimize loads and stores. In this case TBAA knows that a float can not alias and int and optimizes away the load of i.

Now, to the Rule-Book

What exactly does the standard say we are allowed and not allowed to do? The standard language is not straightforward, so for each item I will try to provide code examples that demonstrates the meaning.

What does the C11 standard say?

The C11 standard says the following in section 6.5 Expressions paragraph 7:

An object shall have its stored value accessed only by an lvalue expression that has one of the following types:⁸⁸⁾ — a type compatible with the effective type of the object,

int x = 1;
int *p = &x;   
printf("%d\n", *p); // *p gives us an lvalue expression of type int which is compatible with int

— a qualified version of a type compatible with the effective type of the object,

int x = 1;
const int *p = &x;
printf("%d\n", *p); // *p gives us an lvalue expression of type const int which is compatible with int

— a type that is the signed or unsigned type corresponding to the effective type of the object,

int x = 1;
unsigned int *p = (unsigned int*)&x;
printf("%u\n", *p ); // *p gives us an lvalue expression of type unsigned int which corresponds to 
                     // the effective type of the object

gcc/clang has an extension and also that allows assigning unsigned int* to int* even though they are not compatible types.

— a type that is the signed or unsigned type corresponding to a qualified version of the effective type of the object,

int x = 1;
const unsigned int *p = (const unsigned int*)&x;
printf("%u\n", *p ); // *p gives us an lvalue expression of type const unsigned int which is a unsigned type 
                     // that corresponds with to a qualified verison of the effective type of the object

— an aggregate or union type that includes one of the aforementioned types among its members (including, recursively, a member of a subaggregate or contained union), or

struct foo {
  int x;
};

void foobar( struct foo *fp, int *ip );  // struct foo is an aggregate that includes int among its members so it can
                                         // can alias with *ip

foo f;
foobar( &f, &f.x );

— a character type.

int x = 65;
char *p = (char *)&x;
printf("%c\n", *p );  // *p gives us an lvalue expression of type char which is a character type.
                      // The results are not portable due to endianness issues.

What the C++17 Draft Standard say

The C++17 draft standard in section [basic.lval] paragraph 11 says:

If a program attempts to access the stored value of an object through a glvalue of other than one of the following types the behavior is undefined:⁶³ (11.1) — the dynamic type of the object,

void *p = malloc( sizeof(int) ); // We have allocated storage but not started the lifetime of an object
int *ip = new (p) int{0};        // Placement new changes the dynamic type of the object to int
std::cout << *ip << "\n";        // *ip gives us a glvalue expression of type int which matches the dynamic type 
                                  // of the allocated object

(11.2) — a cv-qualified version of the dynamic type of the object,

int x = 1;
const int *cip = &x;
std::cout << *cip << "\n";  // *cip gives us a glvalue expression of type const int which is a cv-qualified 
                            // version of the dynamic type of x

(11.3) — a type similar (as defined in 7.5) to the dynamic type of the object,

(11.4) — a type that is the signed or unsigned type corresponding to the dynamic type of the object,

// Both si and ui are signed or unsigned types corresponding to each others dynamic types
// We can see from this godbolt(https://godbolt.org/g/KowGXB) the optimizer assumes aliasing.
signed int foo( signed int &si, unsigned int &ui ) {
  si = 1;
  ui = 2;

  return si;
}

(11.5) — a type that is the signed or unsigned type corresponding to a cv-qualified version of the dynamic type of the object,

signed int foo( const signed int &si1, int &si2); // Hard to show this one assumes aliasing

(11.6) — an aggregate or union type that includes one of the aforementioned types among its elements or nonstatic data members (including, recursively, an element or non-static data member of a subaggregate or contained union),

struct foo {
 int x;
};

// Compiler Explorer example(https://godbolt.org/g/z2wJTC) shows aliasing assumption
int foobar( foo &fp, int &ip ) {
 fp.x = 1;
 ip = 2;

 return fp.x;
}

foo f; 
foobar( f, f.x ); 

(11.7) — a type that is a (possibly cv-qualified) base class type of the dynamic type of the object,

struct foo { int x ; };

struct bar : public foo {};

int foobar( foo &f, bar &b ) {
  f.x = 1;
  b.x = 2;

  return f.x;
}

(11.8) — a char, unsigned char, or std::byte type.

int foo( std::byte &b, uint32_t &ui ) {
  b = static_cast<std::byte>('a');
  ui = 0xFFFFFFFF;                   

  return std::to_integer<int>( b );  // b gives us a glvalue expression of type std::byte which can alias
                                     // an object of type uint32_t
}

Worth noting signed char is not included in the list above, this is a notable difference from C which says a character type.

What is Type Punning

We have gotten to this point and we may be wondering, why would we want to alias for? The answer typically is to type pun, often the methods used violate strict aliasing rules.

Sometimes we want to circumvent the type system and interpret an object as a different type. This is called type punning, to reinterpret a segment of memory as another type. Type punning is useful for tasks that want access to the underlying representation of an object to view, transport or manipulate. Typical areas we find type punning being used are compilers, serialization, networking code, etc…

Traditionally this has been accomplished by taking the address of the object, casting it to a pointer of the type we want to reinterpret it as and then accessing the value, or in other words by aliasing. For example:

int x =  1 ;

// In C
float *fp = (float*)&x ;  // Not a valid aliasing

// In C++
float *fp = reinterpret_cast<float*>(&x) ;  // Not a valid aliasing

printf( "%f\n", *fp ) ;

As we have seen earlier this is not a valid aliasing, so we are invoking undefined behavior. But traditionally compilers did not take advantage of strict aliasing rules and this type of code usually just worked, developers have unfortunately gotten used to doing things this way. A common alternate method for type punning is through unions, which is valid in C but undefined behavior in C++ (see live example):

union u1
{
  int n;
  float f;
} ;

union u1 u;
u.f = 1.0f;

printf( "%d\n”, u.n );  // UB in C++ n is not the active member

This is not valid in C++ and some consider the purpose of unions to be solely for implementing variant types and feel using unions for type punning is an abuse.

How do we Type Pun correctly?

The standard method for type punning in both C and C++ is memcpy. This may seem a little heavy handed but the optimizer should recognize the use of memcpy for type punning and optimize it away and generate a register to register move. For example if we know int64_t is the same size as double:

static_assert( sizeof( double ) == sizeof( int64_t ) );  // C++17 does not require a message

we can use memcpy:

void func1( double d ) {
  std::int64_t n;
  std::memcpy(&n, &d, sizeof d); 
  //...

At a sufficient optimization level any decent modern compiler generates identical code to the previously mentioned reinterpret_cast method or union method for type punning. Examining the generated code we see it uses just register mov (live Compiler Explorer Example).

C++20 and bit_cast

In C++20 we may gain bit_cast (implementation available in link from proposal) which gives a simple and safe way to type-pun as well as being usable in a constexpr context.

The following is an example of how to use bit_cast to type pun a unsigned int to float, (see it live):

std::cout << bit_cast<float>(0x447a0000) << "\n" ; //assuming sizeof(float) == sizeof(unsigned int)

In the case where To and From types don't have the same size, it requires us to use an intermediate struct15. We will use a struct containing a sizeof( unsigned int ) character array (assumes 4 byte unsigned int) to be the From type and unsigned int as the To type.:

struct uint_chars {
 unsigned char arr[sizeof( unsigned int )] = {} ;  // Assume sizeof( unsigned int ) == 4
};

// Assume len is a multiple of 4 
int bar( unsigned char *p, size_t len ) {
 int result = 0;

 for( size_t index = 0; index < len; index += sizeof(unsigned int) ) {
   uint_chars f;
   std::memcpy( f.arr, &p[index], sizeof(unsigned int));
   unsigned int result = bit_cast<unsigned int>(f);

   result += foo( result );
 }

 return result ;
}

It is unfortunate that we need this intermediate type but that is the current constraint of bit_cast.

Catching Strict Aliasing Violations

We don't have a lot of good tools for catching strict aliasing in C++, the tools we have will catch some cases of strict aliasing violations and some cases of misaligned loads and stores.

gcc using the flag -fstrict-aliasing and -Wstrict-aliasing can catch some cases although not without false positives/negatives. For example the following cases will generate a warning in gcc (see it live):

int a = 1;
short j;
float f = 1.f; // Originally not initialized but tis-kernel caught 
               // it was being accessed w/ an indeterminate value below

printf("%i\n", j = *(reinterpret_cast<short*>(&a)));
printf("%i\n", j = *(reinterpret_cast<int*>(&f)));

although it will not catch this additional case (see it live):

int *p;

p=&a;
printf("%i\n", j = *(reinterpret_cast<short*>(p)));

Although clang allows these flags it apparently does not actually implement the warnings.

Another tool we have available to us is ASan which can catch misaligned loads and stores. Although these are not directly strict aliasing violations they are a common result of strict aliasing violations. For example the following cases will generate runtime errors when built with clang using -fsanitize=address

int *x = new int[2];               // 8 bytes: [0,7].
int *u = (int*)((char*)x + 6);     // regardless of alignment of x this will not be an aligned address
*u = 1;                            // Access to range [6-9]
printf( "%d\n", *u );              // Access to range [6-9]

The last tool I will recommend is C++ specific and not strictly a tool but a coding practice, don't allow C-style casts. Both gcc and clang will produce a diagnostic for C-style casts using -Wold-style-cast. This will force any undefined type puns to use reinterpret_cast, in general reinterpret_cast should be a flag for closer code review. It is also easier to search your code base for reinterpret_cast to perform an audit.

For C we have all the tools already covered and we also have tis-interpreter, a static analyzer that exhaustively analyzes a program for a large subset of the C language. Given a C verions of the earlier example where using -fstrict-aliasing misses one case (see it live)

int a = 1;
short j;
float f = 1.0 ;

printf("%i\n", j = *((short*)&a));
printf("%i\n", j = *((int*)&f));

int *p; 

p=&a;
printf("%i\n", j = *((short*)p));

tis-interpeter is able to catch all three, the following example invokes tis-kernal as tis-interpreter (output is edited for brevity):

./bin/tis-kernel -sa example1.c 
...
example1.c:9:[sa] warning: The pointer (short *)(& a) has type short *. It violates strict aliasing
              rules by accessing a cell with effective type int.
...

example1.c:10:[sa] warning: The pointer (int *)(& f) has type int *. It violates strict aliasing rules by
              accessing a cell with effective type float.
              Callstack: main
...

example1.c:15:[sa] warning: The pointer (short *)p has type short *. It violates strict aliasing rules by
              accessing a cell with effective type int.

Finally there is TySan which is currently in development. This sanitizer adds type checking information in a shadow memory segment and checks accesses to see if they violate aliasing rules. The tool potentially should be able to catch all aliasing violations but may have a large run-time overhead.

If you don't have an existing local branch, it is truly as simple as:

git fetch
git checkout <remote-branch-name>

For instance if you fetch and there is a new remote tracking branch called origin/feature/Main_Page, just do this:

git checkout feature/Main_Page

This creates a local branch with the same name as the remote branch, tracking that remote branch. If you have multiple remotes with the same branch name, you can use the less ambiguous:

git checkout -t <remote>/<remote-branch-name>

If you already made the local branch and don't want to delete it, see How do you make an existing Git branch track a remote branch?.

I prefer "<!--" "-->" like a "text>"

<script type="text/javascript">
//some javascript here     

@foreach (var item in itens)
{                 
<!--  
   var title = @(item.name)
    ...
-->

</script>

JObject implements IDictionary<string, JToken>, so you can use:

IDictionary<string, JToken> dictionary = x;
if (dictionary.ContainsKey("error_msg"))

... or you could use TryGetValue. It implements both methods using explicit interface implementation, so you can't use them without first converting to IDictionary<string, JToken> though.

Its better to perform this over Master branch

Edit .gitignore file. Add the below line in it.

.idea

Remove .idea folder from remote repo. using below command.

git rm -r --cached .idea

For more info. reference: Removing Files from a Git Repository Without Actually Deleting Them

Stage .gitignore file. Using below command

git add .gitignore

Commit

git commit -m 'Removed .idea folder'

Push to remote

git push origin master

Another solution, for those of us without an internet connection to our development machine is:

Create a folder called system-images in the top level of your SDK directory (next to platforms and tools). Create subdirs android-14 and android-15 (as applicable). Extract the complete armeabi-v7a folder to these directory; sysimg_armv7a-15_r01.zip (from, e.g. google's repository) goes to android-15, sysimg_armv7a-14_r02.zip to android-14.

I've not tried this procedure offline, I finally relented and used my broadband allowance at home, but these are the target locations for these large sysimg's, for future reference.

I've tried creating the image subdirs where they were absent in 14 and 15 but while this allowed the AVD to create an image (for 15 but not 14) it hadn't shown the Android logo after 15 minutes.

    std::cout << max_of(1, 2, 3, 4, 5) << std::endl;
    // Or just use the std library:
    std::cout << std::max({1, 2, 3, 4, 5}) << std::endl;
    return 0;
}

You can wrap the label around the input:

 **<label for="a"><input type="checkbox" id="a">a</label>**

This worked for me.

It is more Ruby-like to ask objects whether they respond to a method you need or not, using respond_to?. This allows both minimal interface and implementation unaware programming.

It is not always applicable of course, thus there is still a possibility to ask about more conservative understanding of "type", which is class or a base class, using the methods you're asking about.

Not sure if this is a good practice, but I noticed I can also get just the value by casting the series as float.

e.g.

rate

3 0.042679

Name: Unemployment_rate, dtype: float64

float(rate)

0.0426789

It's a ternary operator, or the short form for if..else.

condition ? value if true : value if false

See Microsoft Docs | ?: operator (C# reference).

If you want Monday as the start of your week, do this:

$date = '2015-10-12';
$day = date('N', strtotime($date));
$week_start = date('Y-m-d', strtotime('-'.($day-1).' days', strtotime($date)));
$week_end = date('Y-m-d', strtotime('+'.(7-$day).' days', strtotime($date)));

class, interface, or enum expected

The above error is even possible when import statement is miss spelled. A proper statement is "import com.company.HelloWorld;"

If by mistake while code writing/editing it is miss written like "t com.company.HelloWorld;"

compiler will show "class, interface, or enum expected"

As long as the macros in question are in the same workbook and you verify the names exist, you can call those macros from any other module by name, not by module.

So if in Module1 you had two macros Macro1 and Macro2 and in Module2 you had Macro3 and Macro 4, then in another macro you could call them all:

Sub MasterMacro()
    Call Macro1
    Call Macro2
    Call Macro3
    Call Macro4
End Sub

Multiple queries tip for those who don't know (past me and future me)

If you're making a single query with the url just ?autoplay=1 works as shown by mjhm's answer

<iframe src="https://www.youtube.com/embed/oHg5SJYRHA0?autoplay=1"></iframe>

If you're making multiple queries remember the first one begins with a ? while the rest begin with a &

Say you want to turn off related videos but enable autoplay...

This works

I realize I'm a little late to the conversation, but I encountered the exact same issue In my git config I had two entries credentials…

In my .gitconfig file

[credential]
helper = cached
[credentials]
helper = wincred

The Fix: Changed my .gitconfig file to the settings below

[credential]
helper = wincred
[credentials]
helper = wincred

This problem looked familiar so I thought I'd see if I could replicate from the limited amount of information.

A quick search turned up an entry in James Bennett's blog here which mentions that when working with the UserProfile to extend the User model a common mistake in settings.py can cause Django to throw this error.

To quote the blog entry:

The value of the setting is not "appname.models.modelname", it's just "appname.modelname". The reason is that Django is not using this to do a direct import; instead, it's using an internal model-loading function which only wants the name of the app and the name of the model. Trying to do things like "appname.models.modelname" or "projectname.appname.models.modelname" in the AUTH_PROFILE_MODULE setting will cause Django to blow up with the dreaded "too many values to unpack" error, so make sure you've put "appname.modelname", and nothing else, in the value of AUTH_PROFILE_MODULE.

If the OP had copied more of the traceback I would expect to see something like the one below which I was able to duplicate by adding "models" to my AUTH_PROFILE_MODULE setting.

TemplateSyntaxError at /

    app_label, model_name = settings.AUTH_PROFILE_MODULE.split('.')
ValueError: too many values to unpack

This I think is one of the few cases where Django still has a bit of import magic that tends to cause confusion when a small error doesn't throw the expected exception.

You can see at the end of the traceback that I posted how using anything other than the form "appname.modelname" for the AUTH_PROFILE_MODULE would cause the line "app_label, model_name = settings.AUTH_PROFILE_MODULE.split('.')" to throw the "too many values to unpack" error.

I'm 99% sure that this was the original problem encountered here.

Note the Hindi has an accent in my example and that will be rendered as a single character. That's the only issue I faced with this solution.

select (with the read mask set) will return with the handle signalled, but when you use ioctl* to check the number of bytes pending to be read, it will be zero. This is a sign that the socket has been disconnected.

This is a great discussion on the various methods of checking that the client has disconnected: Stephen Cleary, Detection of Half-Open (Dropped) Connections.

* for Windows use ioctlsocket.

Sorry to resurrect an old question, but I thought I might contribute a couple of very basic examples and for-dummies explanations. None of the other answers posted thusfar illustrate syntax like the MDN guide's first example, which is about as basic as one can get.

Getter:

var settings = {
    firstname: 'John',
    lastname: 'Smith',
    get fullname() { return this.firstname + ' ' + this.lastname; }
};

console.log(settings.fullname);

... will log John Smith, of course. A getter behaves like a variable object property, but offers the flexibility of a function to calculate its returned value on the fly. It's basically a fancy way to create a function that doesn't require () when calling.

Setter:

var address = {
    set raw(what) {
        var loc = what.split(/\s*;\s*/),
        area = loc[1].split(/,?\s+(\w{2})\s+(?=\d{5})/);

        this.street = loc[0];
        this.city = area[0];
        this.state = area[1];
        this.zip = area[2];
    }
};

address.raw = '123 Lexington Ave; New York NY  10001';
console.log(address.city);

... will log New York to the console. Like getters, setters are called with the same syntax as setting an object property's value, but are yet another fancy way to call a function without ().

See this jsfiddle for a more thorough, perhaps more practical example. Passing values into the object's setter triggers the creation or population of other object items. Specifically, in the jsfiddle example, passing an array of numbers prompts the setter to calculate mean, median, mode, and range; then sets object properties for each result.

With ES6 syntax

import mongoose from "mongoose";

// Generate a new new ObjectId
const newId2 = new mongoose.Types.ObjectId();
// Convert string to ObjectId
const newId = new mongoose.Types.ObjectId('56cb91bdc3464f14678934ca');

If using function onclick DIV and then want to disable click it again you can use this :

for (var i=0;i<document.getElementsByClassName('ads').length;i++){
    document.getElementsByClassName('ads')[i].onclick = false;
}

Example :
HTML

<div id='mybutton'>Click Me</div>

Javascript

document.getElementById('mybutton').onclick = function () {
    alert('You clicked');
    this.onclick = false;
}

This is a proposal for unordered items. This function works with a single loop and with a hash table and collects all items with their id. If a root node is found, then the object is added to the result array.

The browser's context menu is being overridden. There is no way to augment the native context menu in any major browser.

Since the plugin is creating its own menu, the only part thats really being abstracted is the browser's context menu event. The plugin creates an html menu based on your configuration, then places that content at the location of your click.

Yes, this is the only way to go about creating a custom context menu. Obviously, different plugins do things slightly different, but they will all override the browser's event and place their own html-based menu in the correct place.

@NominSim There may be other character, so I should detect it by length.

private String forceUtf8Coding(String str) {
    str = str.replace("\\","");
    String[] arr = str.split("u");
    StringBuilder text = new StringBuilder();
    for(int i = 1; i < arr.length; i++){
        String a = arr[i];
        String b = "";
        if (arr[i].length() > 4){
            a = arr[i].substring(0, 4);
            b = arr[i].substring(4);
        }
        int hexVal = Integer.parseInt(a, 16);
        text.append((char) hexVal).append(b);
    }
    return text.toString();
}

you can write to a unit, but you can also write to a string

program foo
    character(len=1024) :: filename

    write (filename, "(A5,I2)") "hello", 10

    print *, trim(filename)
end program

Please note (this is the second trick I was talking about) that you can also build a format string programmatically.

program foo

    character(len=1024) :: filename
    character(len=1024) :: format_string
    integer :: i

    do i=1, 10
        if (i < 10) then
            format_string = "(A5,I1)"
        else
            format_string = "(A5,I2)"
        endif

        write (filename,format_string) "hello", i
        print *, trim(filename)
    enddo

end program

A little modification to typescript:

  public encodeData(data: any): string {
    return Object.keys(data).map((key) => {
      return [key, data[key]].map(encodeURIComponent).join("=");
    }).join("&");
  }

I don't know of any JVM that actually checks the JAVA_OPTS environment variable. Usually this is used in scripts which launch the JVM and they usually just add it to the java command-line.

The key thing to understand here is that arguments to java that come before the -jar analyse.jar bit will only affect the JVM and won't be passed along to your program. So, modifying the java line in your script to:

java $JAVA_OPTS -jar analyse.jar $*

Should "just work".

I suspect /ignore is a VC6 link.exe option. for VS2005 and VS2008's linker there's no documented /ignore option available, but the linker looks just ignore the "/ignore:XXX" option, no error and no effect.

I just ran into a similar issue. Recently started developing on windows, so getting used to the PowerShell. Ironically when trying to use 'conda activate ' in Git-bash i got the error

$ conda activate obf

CommandNotFoundError: Your shell has not been properly configured to use 'conda activate'.
If using 'conda activate' from a batch script, change your
invocation to 'CALL conda.bat activate'.

To initialize your shell, run

    $ conda init <SHELL_NAME>

Currently supported shells are:
  - bash
  - cmd.exe
  - fish
  - tcsh
  - xonsh
  - zsh
  - powershell

See 'conda init --help' for more information and options.

IMPORTANT: You may need to close and restart your shell after running 'conda init'. 

Running the command in my PowerShell (elevated) as instructed did the trick for me.

conda init powershell 

This should be true across all terminal environments, just strange PowerShell didn't return this error itself.

All modern browsers now support a simple CSS solution for automatically adding an ellipsis if a line of text exceeds the available width:

p {
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
}

(Note that this requires the width of the element to be limited in some way in order to have any effect.)

Based on https://css-tricks.com/snippets/css/truncate-string-with-ellipsis/.

It should be noted that this approach does not limit based on the number of characters. It also does not work if you need to allow multiple lines of text.

Have a look at localize, or l

eg:

l Time.at(1100897479)

I wonder if this question has been answered well: how css margins work and why is it that margin-top:-5; is not the same as margin-bottom:5;?

Margin is distance from the surroundings of the element. margin-top says "... distance from surroundings as we measure from top 'side' of the element's 'box' and margin-bottom being the distance from the bottom 'side' of the 'box'". Then margin-top:5; is concerned with the top 'side' perimeter,-5 in that case; anything approaching from top 'side' can overlap top 'side' of element by 5, and margin-bottom:5; means distance between element bottom 'side' and surrounding is 5.

Basically that but affected by float'ed elements and the like: http://www.w3.org/TR/CSS2/box.html#margin-properties.

http://coding.smashingmagazine.com/2009/07/27/the-definitive-guide-to-using-negative-margins/

I stand to be corrected.

You can also try this

// create a thread  
Thread newWindowThread = new Thread(new ThreadStart(() =>  
{  
    // create and show the window
    FaxImageLoad obj = new FaxImageLoad(destination);  
    obj.Show();  
    
    // start the Dispatcher processing  
    System.Windows.Threading.Dispatcher.Run();  
}));  

// set the apartment state  
newWindowThread.SetApartmentState(ApartmentState.STA);  

// make the thread a background thread  
newWindowThread.IsBackground = true;  

// start the thread  
newWindowThread.Start();  

The sql server database will be stored by default in the following path

<drive>:\Program Files\Microsoft SQL Server\MSSQL.X\MSSQL\Data\

, where <drive> is the installation drive and X is the instance number (MSSQL.1 for the first instance of the Database Engine). Inorder to provide the connection string you should know what is the server name of the sql server database, where you have stored followed by instance of the database server.

Generally the server name will be like the ip address of the machine where the database is attached and the default instance will be SqlExpress

A connection string contains Data Source name i.e., server name, Initial catalog i.e., database name, user id i.e., login user id of the database, password i.e., login password of the database.

You can't use it in the way you describe. The point about generic types, is that although you may not know them at "coding time", the compiler needs to be able to resolve them at compile time. Why? Because under the hood, the compiler will go away and create a new type (sometimes called a closed generic type) for each different usage of the "open" generic type.

In other words, after compilation,

DoesEntityExist<int>

is a different type to

DoesEntityExist<string>

This is how the compiler is able to enfore compile-time type safety.

For the scenario you describe, you should pass the type as an argument that can be examined at run time.

The other option, as mentioned in other answers, is that of using reflection to create the closed type from the open type, although this is probably recommended in anything other than extreme niche scenarios I'd say.

If you're using greasemonkey, it's possible the page isn't ready for the javascript yet. You may need to use window.onReady.

var inputs;

}

window.onReady = doThisWhenReady;

Such OutofMemoryException cannot be totally resolved by calling the System.gc() and so on .

By referring to the Activity Life Cycle

The Activity States are determined by the OS itself subject to the memory usage for each process and the priority of each process.

You may consider the size and the resolution for each of the bitmap pictures used. I recommend to reduce the size ,resample to lower resolution , refer to the design of galleries (one small picture PNG , and one original picture.)

The underlining problem is simple – lack of permission to /var/run/docker.sock unix domain socket.

From Daemon socket option chapter of Docker Command Line reference for Docker 1.6.0:

By default, a unix domain socket (or IPC socket) is created at /var/run/docker.sock, requiring either root permission, or docker group membership.

Steps necessary to grant rights to users are nicely described in Docker installation instructions for Fedora:

Granting rights to users to use Docker

The docker command line tool contacts the docker daemon process via a socket file /var/run/docker.sock owned by root:root. Though it's recommended to use sudo for docker commands, if users wish to avoid it, an administrator can create a docker group, have it own /var/run/docker.sock, and add users to this group.

$ sudo groupadd docker
$ sudo chown root:docker /var/run/docker.sock
$ sudo usermod -a -G docker $USERNAME

Log out and log back in for above changes to take effect. Please note that Docker packages of some Linux distributions (Ubuntu) do already place /var/run/docker.sock in the docker group making the first two of above steps unnecessary.

In case of OS X and boot2docker the situation is different; the Docker daemon runs inside a VM so the DOCKER_HOST environment variable must be set to this VM so that the Docker client could find the Docker daemon. This is done by running $(boot2docker shellinit) in the shell.

Declare an int variable:

int variable = 0xFF;

Now use char* pointers to various parts of it and check what is in those parts.

char* startPart = reinterpret_cast<char*>( &variable );
char* endPart = reinterpret_cast<char*>( &variable ) + sizeof( int ) - 1;

Depending on which one points to 0xFF byte now you can detect endianness. This requires sizeof( int ) > sizeof( char ), but it's definitely true for the discussed platforms.

setting the tcp_reuse is more useful than changing time_wait, as long as you have the parameter (kernels 3.2 and above, unfortunately that disqualifies all versions of RHEL and XenServer).

Dropping the value, particularly for VPN connected users, can result in constant recreation of proxy tunnels on the outbound connection. With the default Netscaler (XenServer) config, which is lower than the default Linux config, Chrome will sometimes have to recreate the proxy tunnel up to a dozen times to retrieve one web page. Applications that don't retry, such as Maven and Eclipse P2, simply fail.

The original motive for the parameter (avoid duplication) was made redundant by a TCP RFC that specifies timestamp inclusion on all TCP requests.

Handle the Worksheet_Change event or the Workbook_SheetChange event.

The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.

use the time and datetime packages.

if anybody want to execute this script and also find out how much time it took to execute in minutes

import time
from time import strftime
from datetime import datetime 
from time import gmtime

def start_time_():    
    #import time
    start_time = time.time()
    return(start_time)

def end_time_():
    #import time
    end_time = time.time()
    return(end_time)

def Execution_time(start_time_,end_time_):
   #import time
   #from time import strftime
   #from datetime import datetime 
   #from time import gmtime
   return(strftime("%H:%M:%S",gmtime(int('{:.0f}'.format(float(str((end_time-start_time))))))))

start_time = start_time_()
# your code here #
[i for i in range(0,100000000)]
# your code here #
end_time = end_time_()
print("Execution_time is :", Execution_time(start_time,end_time))

The above code works for me. I hope this helps.

Select multiple lines by clicking first line then holding shift and clicking last line. Then press:

CTRL+SHIFT+L

or on MAC: CMD+SHIFT+L (as per comments)

Alternatively you can select lines and go to SELECTION MENU >> SPLIT INTO LINES.

Now you can edit multiple lines, move cursors etc. for all selected lines.

A simple and flexible solution in xml:

<View
  android:layout_width="match_parent"
  android:layout_height="3sp"
  android:layout_alignLeft="@+id/your_text_view_need_underline"
  android:layout_alignRight="@+id/your_text_view_need_underline"
  android:layout_below="@+id/your_text_view_need_underline"
  android:background="@color/your_color" />

Try adding autostart="false" to your source tag.

Take a look at this question and this question for some good answers on C++ object instantiation.

This basic idea is that objects instantiated on the heap (using new) need to be cleaned up manually, those instantiated on the stack (without new) are automatically cleaned up when they go out of scope.

void SomeFunc()
{
    Point p1 = Point(0,0);
} // p1 is automatically freed

void SomeFunc2()
{
    Point *p1 = new Point(0,0);
    delete p1; // p1 is leaked unless it gets deleted
}

Ok, after the information that your Activity extends ListActivity here's a way to implement OnItemClickListener:

public class newListView extends ListView {

    public newListView(Context context) {
        super(context);
    }

    @Override
    public void setOnItemClickListener(
            android.widget.AdapterView.OnItemClickListener listener) {
        super.setOnItemClickListener(listener);
        //do something when item is clicked

    }

}

Open your file, and then do something like...

for line in f:
    nlines += 1
    if (line.find(phrase) >= 0):
        print "Its here.", nlines

There are numerous ways of reading lines from files in Python, but the for line in f technique is more efficient than most.

Router Link

routerLink with brackets and none - simple explanation.

The difference between routerLink= and [routerLink] is mostly like relative and absolute path.

Similar to a href you may want to navigate to ./about.html or https://your-site.com/about.html.

When you use without brackets then you navigate relative and without params;

my-app.com/dashboard/client

"jumping" from my-app.com/dashboard to my-app.com/dashboard/client

<a routerLink="client/{{ client.id }}" .... rest the same

When you use routerLink with brackets then you execute app to navigate absolute and you can add params how is the puzzle of your new link

first of all it will not include the "jump" from dashboard/ to dashboard/client/client-id and bring you data of client/client-id which is more helpful for EDIT CLIENT

<a [routerLink]="['/client', client.id]" ... rest the same

The absolute way or brackets routerLink require additional set up of you components and app.routing.module.ts

The code without error will "tell you more/what is the purpose of []" when you make the test. Just check this with or without []. Than you may experiments with selectors which - as mention above - helps with dynamics routing.

Angular.io Selectors

See whats the routerLink construct

https://angular.io/api/router/RouterLink#selectors

Not tested but should work

 products.sort((a,b)=>a.title.rendered > b.title.rendered)

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
   alert(str2 + " found");
}

I have a page it loads an HTML body from MYSQL I want to present that code in a frame so it renders it self independent of the rest of the page and in the confines of that specific bordering.

An object with a unencoded dataUri might have also fit your need if it was only to load a portion of data text:

The HTML <object> element represents an external resource, which can be treated as an image, a nested browsing context, or a resource to be handled by a plugin.

body {display:flex;min-height:25em;}
p {margin:auto;}
object {margin:0 auto;background:lightgray;}

<p>here My uploaded content: </p>
<object data='data:text/html,
  <style>

.table {
  display: table;
  text-align:center;
  width:100%;
  height:100%;
}

.table > * {
  display: table-row;
}

.table > main {
  display: table-cell;
  height: 100%;
  vertical-align: middle;
}
</style>


<div class="table">
  <header>
    <h1>Title</h1>
    <p>subTitle</p>
  </header>

  <main>
    <p>Collection</p>
    <p>Version</p>
    <p>Id</p>
  </main>

  <footer>
    <p>Edition</p>
  </footer>'>

</object>

But keeping your Iframe idea, You could also load your HTML inside your iframe tag and set it as the srcdoc value.You should not have to mind about quotes nor turning it into a dataUri but only mind to fire onload once.

The HTML Inline Frame element (<iframe>) represents a nested browsing context, embedding another HTML page into the current one.

Both iframe below will render the same, one require extra javascript.

example loading a full document :

body {
  display: flex;
  min-height: 25em;
}

p {
  margin: auto;
}

iframe {
  margin: 0 auto;
  min-height: 100%;
  background:lightgray;

you didn't use time() function that returns the current time measured in the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT). use like this:

$date = strtotime(time());
$date = strtotime("+7 day", $date);
echo date('M d, Y', $date);

In this case, I'd recommend using break labels.

http://www.java-examples.com/break-statement

This way you can specifically call it outside of the for loop.

Step 1: Define attributes in $appends
Step 2: Define accessor for that attributes.
Example:

<?php
...

class Movie extends Model{

    protected $appends = ['cover'];

    //define accessor
    public function getCoverAttribute()
    {
        return json_decode($this->InJson)->cover;
    }

Think of ! (negation operator) as "not", || (boolean-or operator) as "or" and && (boolean-and operator) as "and". See Operators and Operator Precedence.

Thus:

if(!(a || b)) {
  // means neither a nor b
}

However, using De Morgan's Law, it could be written as:

if(!a && !b) {
  // is not a and is not b
}

a and b above can be any expression (such as test == 'B' or whatever it needs to be).

Once again, if test == 'A' and test == 'B', are the expressions, note the expansion of the 1st form:

// if(!(a || b)) 
if(!((test == 'A') || (test == 'B')))
// or more simply, removing the inner parenthesis as
// || and && have a lower precedence than comparison and negation operators
if(!(test == 'A' || test == 'B'))
// and using DeMorgan's, we can turn this into
// this is the same as substituting into if(!a && !b)
if(!(test == 'A') && !(test == 'B'))
// and this can be simplified as !(x == y) is the same as (x != y)
if(test != 'A' && test != 'B')

• You should use only one adapter binded with the list of data you need to list
• When you need to remove and replace all items, you have to clear all items from data-list using "list.clear()" and then add new data using "list.addAll(List)"

here an example:

List<String> myList = new ArrayList<String>();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,       android.R.layout.simple_list_item_1, myList);
listview.setAdapter(adapter);
listview.setOnItemClickListener(this);

populateList(){
   List<String> result = getDataMethods();

   myList.addAll(result);
   adapter.notifyDataSetChanged();
}

repopulateList(){
   List<String> result = getDataMethods();

   myList.clear();
   myList.addAll(result);
   adapter.notifyDataSetChanged();
}

I use the mouse:

1. mark
2. right click -> copy
3. right click -> paste

I like the Character.digit solution, but here is how I solved it

public byte[] hex2ByteArray( String hexString ) {
    String hexVal = "0123456789ABCDEF";
    byte[] out = new byte[hexString.length() / 2];

    int n = hexString.length();

    for( int i = 0; i < n; i += 2 ) {
        //make a bit representation in an int of the hex value 
        int hn = hexVal.indexOf( hexString.charAt( i ) );
        int ln = hexVal.indexOf( hexString.charAt( i + 1 ) );

        //now just shift the high order nibble and add them together
        out[i/2] = (byte)( ( hn << 4 ) | ln );
    }

    return out;
}

One possiblity is to use a NULL pointer as a flag value:

const char *list[] = {"dog", "cat", NULL};
for (char **iList = list; *iList != NULL; ++iList)
{
    cout << *iList;
}

Postman API Access

3. use these settings with oauth2 in Postman:

   • Auth URL = https://accounts.google.com/o/oauth2/auth

   • Access Token URL = https://accounts.google.com/o/oauth2/token

     4. Choose Scope for the HTTP API
     5. Generate Token
     6. to add Schema use:

SCOPE = https: //www.googleapis.com/auth/admin.directory.userschema

post https: //www.googleapis.com/admin/directory/v1/customer/customer-id/schemas

{
  "fields": [
    {
      "fieldName": "role",
      "fieldType": "STRING",
      "multiValued": true,
      "readAccessType": "ADMINS_AND_SELF"
    }
  ],
  "schemaName": "SAML"
}

7. to patch user use:

SCOPE = https://www.googleapis.com/auth/admin.directory.user

PATCH https://www.googleapis.com/admin/directory/v1/users/[email protected]

 {
  "customSchemas": {
     "SAML": {
       "role": [
         {
          "value": "arn:aws:iam::123456789123:role/Admin,arn:aws:iam::123456789123:saml-provider/GoogleApps",
          "customType": "Admin"
         }
       ]
     }
   }
}

I realize this is really old, but I'm just getting started with ASP.NET MVC, so I thought I'd stick my two cents in:

• Request.IsAuthenticated tells you if the user is authenticated.
• Page.User.Identity gives you the identity of the logged-in user.

If you are using numpy, you can perform extended slicing like that:

>>> import numpy
>>> a=numpy.array(['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h'])
>>> Idx = [0, 3, 7]
>>> a[Idx]
array(['a', 'd', 'h'], 
      dtype='|S1')

...and is probably much faster (if performance is enough of a concern to to bother with the numpy import)

• DTR - Data Terminal Ready
• DSR - Data Set Ready
• RTS - Request To Send
• CTS - Clear To Send

There are multiple ways of doing things because there were never any protocols built into the standards. You use whatever ad-hoc "standard" your equipment implements.

Just based on the names, RTS/CTS would seem to be a natural fit. However, it's backwards from the needs that developed over time. These signals were created at a time when a terminal would batch-send a screen full of data, but the receiver might not be ready, thus the need for flow control. Later the problem would be reversed, as the terminal couldn't keep up with data coming from the host, but the RTS/CTS signals go the wrong direction - the interface isn't orthogonal, and there's no corresponding signals going the other way. Equipment makers adapted as best they could, including using the DTR and DSR signals.

EDIT

To add a bit more detail, its a two level hierarchy so "officially" both must happen for communication to take place. The behavior is defined in the original CCITT (now ITU-T) standard V.28.

The DCE is a modem connecting between the terminal and telephone network. In the telephone network was another piece of equipment which split off to the data network, eg. X.25.

The modem has three states: Powered off, Ready (Data Set Ready is true), and connected (Data Carrier Detect)

The terminal can't do anything until the modem is connected.

When the modem wants to send data, it raises RTS and the modem grants the request with CTS. The modem lowers CTS when its internal buffer is full.

So nostalgic!

For Kotlin Users

val params = mImageView?.layoutParams as FrameLayout.LayoutParams
params.width = FrameLayout.LayoutParams.MATCH_PARENT
params.height = FrameLayout.LayoutParams.MATCH_PARENT
mImageView?.layoutParams = params

Here I used FrameLayout.LayoutParams since my views( ImageView) parent is FrameLayout

Well for me the problem got resolved by adding the jars in my APACHE/TOMCAT/lib folder ! .

Remember that sizes on the web are increasing dramatically. 3 years ago, I did an overhaul to bring our 500 px wide site layout to 1000. Now, where many sites are doing the jump to 1200, we jumped past that and went to a 2560 max optimized for 1600 wide (or 80% depending on the content level) main content area with responsiveness to allow the exact same ratios and look and feel on a laptop (1366x768) and on mobile (1280x720 or smaller).

Dynamic resizing is an integral part of this and will only become more-so as responsiveness becomes more and more important in 2013.

My smartphone has no trouble dealing with the content with 25 items on a page being resized - neither the computation for resizing nor the bandwidth. 3 seconds loads the page from fresh. Looks great on our 6 year old presentation laptop (1366x768) and on the projector (800x600).

Only on Mozilla Firefox does it look genuinely atrocious. It even looks just fine on IE8 (never used/updated since I installed it 2.5 years ago).

There is one more option now ( January-2015 )

1. Create a new private repo
2. On the empty repo screen there is an "import" option/button
3. click it and put the existing github repo url There is no github option mention but it works with github repos too.
4. DONE

A lot has been said already, but to make it simple, here's my take. Interfaces are intended to have method contracts to be implemented by the consumers or classes and not to have fields to store values.

You may argue that then why properties are allowed? So the simple answer is - properties are internally defined as methods only.

The easiest way to solve this problem in Angular is to do:

In Template:

<select [ngModel]="selectedObjectIndex">
  <option [value]="i" *ngFor="let object of objects; let i = index;">{{object.name}}</option>
</select>

In your class:

this.selectedObjectIndex = 1/0/your number wich item should be selected

The following demonstrates an alternative approach for returning a key pair object using the form of (a, b). The first example uses the string 'key' as the property name, and 'val' as the value.

Example #1:

(function(o,a,b){return o[a]=b,o})({},'key','val');

Example: #2:

var obj = { foo: 'bar' };
(function(o,a,b){return o[a]=b,o})(obj,'key','val');

As shown in the second example, this can modify existing objects, too (if property is already defined in the object, value will be overwritten).

Result #1: { key: 'val' }

Result #2: { foo: 'bar', key: 'val' }

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

The accepted answer works well except for the fact that the javascript is briefly displayed in whatever the ajax target element is. To get around this, create a partial view called _Redirect with the following code:

@model string
<script>
   window.location = '@Model';
</script>

Then, in the controller replace

return Redirect(Url.Action("Index", "Home"));

with

return PartialView("_Redirect",Url.Action("Index", "Home"));

The effect is the same as the accepted answer, but without the brief artifact in the display. Place the _Redirect.cshtml in the shared folder so it can be used from anywhere.

Click on the restore button. console.log will start to work.

For those who use Mac, edit this file:

/Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh

Mine had:

export JAVA_HOME=`/usr/libexec/java_home -v 1.7`

and I changed it to 1.8 and it stopped complaining about java version.

When you have image into yours drawable gallery then you just need to pick the option of image view pick and drag into app activity you want to show and select the required image.

Suppose cellspcing / cellpadding / border-spacing property did not worked, you can use the code as follow.

<div class="form-group">
  <table width="100%" cellspacing="2px" style="border-spacing: 10px;">
    <tr>                        
      <td width="47%">
        <input type="submit" class="form-control btn btn-info" id="submit" name="Submit" />
      </td>
      <td width="5%"></td>
      <td width="47%">
        <input type="reset" class="form-control btn btn-info" id="reset" name="Reset" />
      </td>
    </tr>
  </table>
</div>

I've tried and got succeed while seperate the button by using table-width and make an empty td as 2 or 1% it doesn't return more different.

I had the same problem recently.

First you need to install HAXM in the Android SDK Manager (from the error message I think you already did that). This will enable the emulator to use the HAXM framework, and for this it needs to open the HAX device. On your system this cannot be found, hence the error message.

To make this device available, you need to install the HAXM driver from Intel. You can find it here: http://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager (You also need to enable virtualization in your computer BIOS).

Hope this helps.

try this code

using hidden field we can pass php varibale to another page

page1.php

<?php $myVariable = "Some text";?>
<form method="post" action="page2.php">
 <input type="hidden" name="text" value="<?php echo $myVariable; ?>">
 <button type="submit">Submit</button>
</form>

pass php variable to hidden field value so you can access this variable into another page

page2.php

<?php
 $text=$_POST['text'];
 echo $text;
?>

The last place I had to unbox something was when writing some code that retrieved some data from a database (I wasn't using LINQ to SQL, just plain old ADO.NET):

int myIntValue = (int)reader["MyIntValue"];

Basically, if you're working with older APIs before generics, you'll encounter boxing. Other than that, it isn't that common.

I advise you to go with Scanner instead of DataInputStream. Scanner is specifically designed for this purpose and introduced in Java 5. See the following links to know how to use Scanner.

• Java Documentation
• Java Tutorial

Example

Scanner s = new Scanner(System.in);
System.out.println(s.nextInt());
System.out.println(s.nextInt());
System.out.println(s.next());
System.out.println(s.next());

To get the details about the error I had to add ASPNETCORE_ENVIRONMENT environment variable for the corresponding Application Pool system.applicationHost/applicationPools.

Note: the web application in my case was ASP.NET Core 2 web application hosted on IIS 10. It can be done via Configuration Editor in IIS Manager (see Editing Collections with Configuration Editor to figure out where to find this editor in IIS Manager).

this should be on here: it works anyway. And it looks good compared to the above ones.

hlsl code

        float3 Hue(float H)
        {
            half R = abs(H * 6 - 3) - 1;
            half G = 2 - abs(H * 6 - 2);
            half B = 2 - abs(H * 6 - 4);
            return saturate(half3(R,G,B));
        }

        half4 HSVtoRGB(in half3 HSV)
        {
            return half4(((Hue(HSV.x) - 1) * HSV.y + 1) * HSV.z,1);
        }

float3 is 16 bit precision vector3 data type, i.e. float3 hue() is returns a data type (x,y,z) e.g. (r,g,b), half is same with half precision, 8bit, a float4 is (r,g,b,a) 4 values.

Any class which extends Exception class will be a user defined Checked exception class where as any class which extends RuntimeException will be Unchecked exception class. as mentioned in User defined exception are checked or unchecked exceptions So, not throwing the checked exception(be it user-defined or built-in exception) gives compile time error.

Checked exception are the exceptions that are checked at compile time.

Unchecked exception are the exceptions that are not checked at compiled time

i did this and works: i have my project in D: and my batch file is in the desktop, if u have it in the same drive just ignore the first line and change de D directory in the second line

in the second line change the folder of the file, put your folder

in the third line change the name of the file

D: cd D:\python_proyects\example_folder\ python example_file.py

One other option would be to use something like this

SELECT  * 
FROM    table t INNER JOIN
        (
            SELECT  'Text%' Col
            UNION SELECT 'Link%'
            UNION SELECT 'Hello%'
            UNION SELECT '%World%'
        ) List ON t.COLUMN LIKE List.Col

I found it pretty easy like this

    using System;
    using System.Data;
    using System.IO;
    using Excel;

    public DataTable ExcelToDataTableUsingExcelDataReader(string storePath)
    {
        FileStream stream = File.Open(storePath, FileMode.Open, FileAccess.Read);

        string fileExtension = Path.GetExtension(storePath);
        IExcelDataReader excelReader = null;
        if (fileExtension == ".xls")
        {
            excelReader = ExcelReaderFactory.CreateBinaryReader(stream);
        }
        else if (fileExtension == ".xlsx")
        {
            excelReader = ExcelReaderFactory.CreateOpenXmlReader(stream);
        }

        excelReader.IsFirstRowAsColumnNames = true;
        DataSet result = excelReader.AsDataSet();
        var test = result.Tables[0];
        return result.Tables[0];
    }

Note: you need to install SharpZipLib package for this

Install-Package SharpZipLib

neat and clean! ;)

Your main problem is thinking that the variable you declared outside of the template is the same variable being "set" inside the choose statement. This is not how XSLT works, the variable cannot be reassigned. This is something more like what you want:

<xsl:template match="class">
  <xsl:copy><xsl:apply-templates select="@*|node()"/></xsl:copy>
  <xsl:variable name="subexists">
    <xsl:choose>
      <xsl:when test="joined-subclass">true</xsl:when>
      <xsl:otherwise>false</xsl:otherwise>
    </xsl:choose>
  </xsl:variable>
  subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

And if you need the variable to have "global" scope then declare it outside of the template:

<xsl:variable name="subexists">
  <xsl:choose>
     <xsl:when test="/path/to/node/joined-subclass">true</xsl:when>
     <xsl:otherwise>false</xsl:otherwise>
  </xsl:choose>
</xsl:variable>

<xsl:template match="class">
   subexists:      <xsl:value-of select="$subexists" />
</xsl:template>

You need to use "protocols" to delegate or provide data to the AsynTask.

Delegates and Data Sources

A delegate is an object that acts on behalf of, or in coordination with, another object when that object encounters an event in a program. (Apple definition)

protocols are interfaces that define some methods to delegate some behaviors.

Here is a complete example!!!

Indexing a list is done using double bracket, i.e. hypo_list[[1]] (e.g. have a look here: http://www.r-tutor.com/r-introduction/list). BTW: read.table does not return a table but a dataframe (see value section in ?read.table). So you will have a list of dataframes, rather than a list of table objects. The principal mechanism is identical for tables and dataframes though.

Note: In R, the index for the first entry is a 1 (not 0 like in some other languages).

Dataframes

l <- list(anscombe, iris)   # put dfs in list
l[[1]]             # returns anscombe dataframe

anscombe[1:2, 2]   # access first two rows and second column of dataset
[1] 10  8

l[[1]][1:2, 2]     # the same but selecting the dataframe from the list first
[1] 10  8

Table objects

tbl1 <- table(sample(1:5, 50, rep=T))
tbl2 <- table(sample(1:5, 50, rep=T))
l <- list(tbl1, tbl2)  # put tables in a list

tbl1[1:2]              # access first two elements of table 1 

Now with the list

l[[1]]                 # access first table from the list

1  2  3  4  5 
9 11 12  9  9 

l[[1]][1:2]            # access first two elements in first table

1  2 
9 11 

In my case on Edge browser:

  const formData = new FormData(this.form);
  for (const [key, value] of formData.entries()) {
      formObject[key] = value;
  }

give me the same error

So I'm not using FormData and i just manually build an object

import React from 'react';    
import formDataToObject from 'form-data-to-object';

  ...

let formObject = {};

// EDGE compatibility -  replace FormData by
for (let i = 0; i < this.form.length; i++) {
  if (this.form[i].name) {
    formObject[this.form[i].name] = this.form[i].value;
  }
}

const data = formDataToObject.toObj(formObject): // convert "user[email]":"[email protected]" => "user":{"email":"[email protected]"}

const orderRes = await fetch(`/api/orders`, {
        method: 'POST',
        credentials: 'same-origin',
        headers: {
          'Content-Type': 'application/json'
        },
        body: JSON.stringify(data)
      });

const order = await orderRes.json();

It might be easier with vlookup. Try this:

=IFERROR(VLOOKUP(D2,G:H,2,0),"")

The IFERROR() is for no matches, so that it throws "" in such cases.

VLOOKUP's first parameter is the value to 'look for' in the reference table, which is column G and H.

VLOOKUP will thus look for D2 in column G and return the value in the column index 2 (column G has column index 1, H will have column index 2), meaning that the value from column H will be returned.

The last parameter is 0 (or equivalently FALSE) to mean an exact match. That's what you need as opposed to approximate match.

First, I don't understand why you are adding all the keys and values count times, Index is never used.

I tried this example :

        var source = new BindingSource();
        List<MyStruct> list = new List<MyStruct> { new MyStruct("fff", "b"),  new MyStruct("c","d") };
        source.DataSource = list;
        grid.DataSource = source;

and that work pretty well, I get two columns with the correct names. MyStruct type exposes properties that the binding mechanism can use.

    class MyStruct
   {
    public string Name { get; set; }
    public string Adres { get; set; }


    public MyStruct(string name, string adress)
    {
        Name = name;
        Adres = adress;
    }
  }

Try to build a type that takes one key and value, and add it one by one. Hope this helps.

You can still unit test a void method by asserting that it had the appropriate side effect. In your method1 example, your unit test might look something like:

public void checkIfValidElementsWithDollarSign() {
    checkIfValidElement("$",19);
    assert ErrorFile.errorMessages.contains("There is a dollar sign in the specified parameter");
}

using uncontrolled fields:

export default class MyComponent extends React.Component {

    onSubmit(e) {
        e.preventDefault();
        console.log(e.target.neededField.value);
    }

    render(){
        return (
            ...
            <form onSubmit={this.onSubmit} className="form-horizontal">
                ...
                <input type="text" name="neededField" className="form-control" ref={(c) => this.title = c} name="title" />
                ...
            </form>
            ...
            <button type="button" className="btn">Save</button>
            ...
        );
    }

};

My solution with Angular 4.0.1: Just showing the UI for required CVC input - where the CVC must be exactly 3 digits:

    <form #paymentCardForm="ngForm">         
...
        <md-input-container align="start">
            <input #cvc2="ngModel" mdInput type="text" id="cvc2" name="cvc2" minlength="3" maxlength="3" placeholder="CVC" [(ngModel)]="paymentCard.cvc2" [disabled]="isBusy" pattern="\d{3}" required />
            <md-hint *ngIf="cvc2.errors && (cvc2.touched || submitted)" class="validation-result">
                <span [hidden]="!cvc2.errors.required && cvc2.dirty">
                    CVC is required.
                </span>
                <span [hidden]="!cvc2.errors.minlength && !cvc2.errors.maxlength && !cvc2.errors.pattern">
                    CVC must be 3 numbers.
                </span>
            </md-hint>
        </md-input-container>
...
<button type="submit" md-raised-button color="primary" (click)="confirm($event, paymentCardForm.value)" [disabled]="isBusy || !paymentCardForm.valid">Confirm</button>
</form>

This should do:

$chunk = "abc\tdef\tghi";

If you want to achieve a shadow like the one that Android does in the Launcher, we're managing these values. They're useful if you want to create TextViews that will appear as a Widget, without a background.

android:shadowColor="#94000000"
android:shadowDy="2"
android:shadowRadius="4"
