After Php 7.1, The accepted answer won't work for all types of relationships.

Because depending of type the relationship, Eloquent will return a Collection, a Model or Null. And in Php 7.1 count(null) will throw an error.

So, to check if the relation exist you can use:

For relationships single: For example hasOne and belongsTo

if(!is_null($model->relation)) {
   ....
}

For relationships multiple: For Example: hasMany and belongsToMany

if ($model->relation->isNotEmpty()) {
   ....
}

Steps to get sources of a jar file as a zip :

1. Download JD-GUI from http://java-decompiler.github.io/ and save it at any location on your system.

2. Drag and drop the jar or open .jar file for which you want the sources on the JD.

3. Java Decompiler will open with all the package structure in a tree format.

4. Click on File menu and select save jar sources. It will save the sources as a zip with the same name as the jar.

Example:-

We can use Eclipse IDE for Java EE Developers as well for update/extract code if require.

From eclipse chose Import Jar and then select jar which you need. Follow instruction as per image below

Solution Working in the Year 2020 and 2021:

I tried the other solutions and nothing worked. This is because of input logic in React.js has been changed. For detail, you can see this link: https://hustle.bizongo.in/simulate-react-on-change-on-controlled-components-baa336920e04.

In short, when we change the value of input by changing state and then dispatch a change event then React will register both the setState and the event and consider it a duplicate event and swallow it.

The solution is to call native value setter on input (See setNativeValue function in following code)

Example Code

import React, { Component } from 'react'
export class CustomInput extends Component {

    inputElement = null;
    
    // THIS FUNCTION CALLS NATIVE VALUE SETTER
    setNativeValue(element, value) {
        const valueSetter = Object.getOwnPropertyDescriptor(element, 'value').set;
        const prototype = Object.getPrototypeOf(element);
        const prototypeValueSetter = Object.getOwnPropertyDescriptor(prototype, 'value').set;

        if (valueSetter && valueSetter !== prototypeValueSetter) {
            prototypeValueSetter.call(element, value);
        } else {
            valueSetter.call(element, value);
        }
    }


    constructor(props) {
        super(props);

        this.state = {
            inputValue: this.props.value,
        };
    }

    addToInput = (valueToAdd) => {
        this.setNativeValue(this.inputElement, +this.state.inputValue + +valueToAdd);
        this.inputElement.dispatchEvent(new Event('input', { bubbles: true }));
    };

    handleChange = e => {
        console.log(e);
        this.setState({ inputValue: e.target.value });
        this.props.onChange(e);
    };

    render() {
        return (
            <div>
                <button type="button" onClick={() => this.addToInput(-1)}>-</button>
                <input
                    readOnly
                    ref={input => { this.inputElement = input }}
                    name={this.props.name}
                    value={this.state.inputValue}
                    onChange={this.handleChange}></input>
                <button type="button" onClick={() => this.addToInput(+1)}>+</button>
            </div>
        )
    }
}

export default CustomInput

Result

in Angular 2.x.x , 4, 5 ...

<form #loginForm="ngForm">
    <input type="text" required> 
    <button  type="submit"  [disabled]="loginForm.form.invalid">Submit</button>
</form>

You can use Chr(13). Then just wrap the whole thing in Chr(34). Chr(34) is double quotes.

• VB.Net Example:
• TheContactInfo = ""
• TheContactInfo = Trim(TheEmail) & chr(13)
• TheContactInfo = TheContactInfo & Trim(ThePhone) & chr(13)
• TheContactInfo = Chr(34) & TheContactInfo & Chr(34)

The answers provided are not the solution. The .NET 6# stuff is pretty different from what we used to. A lot has changed, from having to deal with portable libraries to Visual Studio 2015 installing an old compiler (it cost me four hours cracking my head).

The long story short: Stack Overflow question How do I use C# 6 with a Web Site project type?

You need to install the C# .NET compiler (now runs as a service bla bla bla). and you need to run updates on NuGet to get the latest everything (before trying anything else).

The compiler must be installed on the project your solution runs from (so your website or your main project your application starts from (if you have multiple projects)).

Once you install that then sort out your web.config referencing any portable libraries, and delete both the bin and obj folder (to avoid works on my computer nightmare), It should just run. But be patient; what happens on your machine may vary as much as the answers above. Most of the answers above hide other problems. It may work for a while, then boom: compiler error. I had a few pages working, then some pages started failing because of some packages that have started using portable libraries.

Steps to debug coredump using GDB:

Some generic help:

gdb start GDB, with no debugging les

gdb program begin debugging program

gdb program core debug coredump core produced by program

gdb --help describe command line options

1. First of all, find the directory where the corefile is generated.

2. Then use ls -ltr command in the directory to find the latest generated corefile.

3. To load the corefile use

   gdb binary path of corefile
   

   This will load the corefile.

4. Then you can get the information using the bt command.

   For a detailed backtrace use bt full.

5. To print the variables, use print variable-name or p variable-name

6. To get any help on GDB, use the help option or use apropos search-topic

7. Use frame frame-number to go to the desired frame number.

8. Use up n and down n commands to select frame n frames up and select frame n frames down respectively.

9. To stop GDB, use quit or q.

If you're using Java 8 or up, you can use a library I just released: https://github.com/robtimus/try-parse. It has support for int, long and boolean that doesn't rely on catching exceptions. Unlike Guava's Ints.tryParse it returns OptionalInt / OptionalLong / Optional, much like in https://stackoverflow.com/a/38451745/1180351 but more efficient.

In my case, the auto-generated project appcompat_v7 was closed. So just open up that project in Package Explorer.

Hope this help.

First of all, your description is misleading. Double is a floating point data type. You presumably want to pad your digits with leading zeros in a string. The following code does that:

$s = sprintf('%02d', $digit);

For more information, refer to the documentation of sprintf.

I'm just putting the tutorial from the link ihrupin posted here in this post.

package com.hrupin.cleaner;

import java.io.File;

import android.app.Application;
import android.util.Log;

public class MyApplication extends Application {

    private static MyApplication instance;

    @Override
    public void onCreate() {
        super.onCreate();
        instance = this;
    }

    public static MyApplication getInstance() {
        return instance;
    }

    public void clearApplicationData() {
        File cacheDirectory = getCacheDir();
        File applicationDirectory = new File(cacheDirectory.getParent());
        if (applicationDirectory.exists()) {
            String[] fileNames = applicationDirectory.list();
            for (String fileName : fileNames) {
                if (!fileName.equals("lib")) {
                    deleteFile(new File(applicationDirectory, fileName));
                }
            }
        }
    }

    public static boolean deleteFile(File file) {
        boolean deletedAll = true;
        if (file != null) {
            if (file.isDirectory()) {
                String[] children = file.list();
                for (int i = 0; i < children.length; i++) {
                    deletedAll = deleteFile(new File(file, children[i])) && deletedAll;
                }
            } else {
                deletedAll = file.delete();
            }
        }

        return deletedAll;
    }
}

So if you want a button to do this you need to call MyApplication.getInstance(). clearApplicationData() from within an onClickListener

Update: Your SharedPreferences instance might hold onto your data and recreate the preferences file after you delete it. So your going to want to get your SharedPreferences object and

prefs.edit().clear().commit();

Update:

You need to add android:name="your.package.MyApplication" to the application tag inside AndroidManifest.xml if you had not done so. Else, MyApplication.getInstance() returns null, resulting a NullPointerException.

Chain selectors are not limited just to classes, you can do it for both classes and ids.

Classes

.classA.classB {
/*style here*/
}

Class & Id

.classA#idB {
/*style here*/
}

Id & Id

#idA#idB {
/*style here*/
}

All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".

For your case

li.left.ui-class-selector {
/*style here*/
}

or

.left.ui-class-selector {
/*style here*/
}

Since Singleton Pattern is about having a private constructor and calling some method to control the instantiations (like some getInstance), in Enums we already have an implicit private constructor.

I don't exactly know how the JVM or some container controls the instances of our Enums, but it seems it already use an implicit Singleton Pattern, the difference is we don't call a getInstance, we just call the Enum.

these code is converted code from gbk answer in swift 4

1.in your main controllview :

 if let filePath = Bundle.main.path(forResource: "clip", ofType: "mp4") {
            let fileURL = NSURL(fileURLWithPath: filePath)
            videoPlayer = VideoPlayer(urlAsset: fileURL, view: playerView)
            if let player = videoPlayer {
                player.playerRate = 1.00
            }
        }

       get {

       }
   }
   
   
   var player:AVPlayer? {
       set {
           if let layer = layer as? AVPlayerLayer {
               layer.player = player
           }
       }
       get {
           if let layer = layer as? AVPlayerLayer {
               return layer.player
           } else {
               return nil
           }
       }
   }
   }
   

If your JDK version is right. Another reason that may cause this error is that your Android Studio is in a low version, but your Gradle version is too high. Upgrade your IDE to a newer version may help this.

The answer is yes, there is.

First you can easily install numpy use commands:

pip install numpy

Then you should install mkl, which is required by Scipy, and you can download it here

After download the file_name.whl you install it

C:\Users\****\Desktop\a> pip install mkl_service-1.1.2-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\mkl_service-1.1.2-cp35-cp35m-win32.whl 
Installing collected packages: mkl-service    
Successfully installed mkl-service-1.1.2

Then at the same website you can download scipy-0.18.1-cp35-cp35m-win32.whl

Note:You should download the file_name.whl according to you python version, if you python version is 32bit python3.5 you should download this one, and the "win32" is about your python version, not your operating system version.

Then install file_name.whl like this:

C:\Users\****\Desktop\a>pip install scipy-0.18.1-cp35-cp35m-win32.whl
Processing c:\users\****\desktop\a\scipy-0.18.1-cp35-cp35m-win32.whl
Installing collected packages: scipy
Successfully installed scipy-0.18.1

Then there is only one more thing to do: comment out a specfic line or there will be error messages when you imput command "import scipy".

So comment out this line

from numpy._distributor_init import NUMPY_MKL  # requires numpy+mkl

in this file: your_own_path\lib\site-packages\scipy__init__.py

Then you can use SciPy :)

Here tells you more about the last step.

Here is a similar anwser to a similar question.

General form is:

var ids = []; <= this is your array/collection
var csv = ids.join(",");

For your case you will have to adapt a little bit

You can accomplish this via Maps. Something like

Map<String, String>[] arr = new HashMap<String, String>[2]();
arr[0].put("name", "demo");

But as you start using Java I am sure you will find that if you create a class/model that represents your data will be your best options. I would do

class Person{
String name;
String fname;
}
List<Person> people = new ArrayList<Person>();
Person p = new Person();
p.name = "demo";
p.fname = "fdemo";
people.add(p);

We can schedule the timer to do the work.After the end of the time we set the message won't send.

This is the code.

Timer timer=new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
    @Override
    public void run() {
            //here you can write the code for send the message
        }
    }, 10, 60000);

In here the method we are calling is,

public void scheduleAtFixedRate (TimerTask task, long delay, long period)

In here,

task : the task to schedule

delay: amount of time in milliseconds before first execution.

period: amount of time in milliseconds between subsequent executions.

For more information you can refer: Android Developer

You can stop the timer by calling,

timer.cancel();

The openssl documentation says that file supplied as the -in argument must be in PEM format.

Turns out that, contrary to the CA's manual, the certificate returned by the CA which I stored in myCert.cer is not PEM format rather it is PKCS7.

In order to create my .p12, I had to first convert the certificate to PEM:

openssl pkcs7 -in myCert.cer -print_certs -out certs.pem

and then execute

openssl pkcs12 -export -out keyStore.p12 -inkey myKey.pem -in certs.pem

The runtime or execution environment is the part of a language implementation which executes code and is present at run-time; the compile-time part of the implementation is called the translation environment in the C standard.

Examples:

• the Java runtime consists of the virtual machine and the standard library

• a common C runtime consists of the loader (which is part of the operating system) and the runtime library, which implements the parts of the C language which are not built into the executable by the compiler; in hosted environments, this includes most parts of the standard library

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

I know its late but it might be helpful for those that want other ways. Another way array key=>values can be stored is by using an array method called map(); (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map) you can use arrow function too

 
    var countries = ['Canada','Us','France','Italy'];  

    // Arrow Function  

    countries.map((value, key) => key+ ' : ' + value );  

    // Anonomous Function  

    countries.map(function(value, key){  

         return key + " : " + value;  

    });  

    

No, but you could have something like:

bool b;
b = b.YourExtensionMethod();

This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.

However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.

In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.

Example Code

Here is a simple example based on a SAP system I have access to.

Public Sub SimpleSAPExport()
  Set SapGuiAuto  = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
  Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI 
  Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
  Set session = SAPCon.Children(0) 'Get the first session (window) on that connection

  'Start the transaction to view a table
  session.StartTransaction "SE16"

  'Select table T001
  session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
  session.findById("wnd[0]/tbar[1]/btn[7]").Press

  'Set our selection criteria
  session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
  session.findById("wnd[0]/tbar[1]/btn[8]").press

  'Click the export to file button
  session.findById("wnd[0]/tbar[1]/btn[45]").press

  'Choose the export format
  session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
  session.findById("wnd[1]/tbar[0]/btn[0]").press

  'Choose the export filename
  session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
  session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"

  'Export the file
  session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub

Script Recording

To help find the names of elements such aswnd[1]/tbar[0]/btn[0] you can use script recording. Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.

Within that the More button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.

Edit: Early and Late binding

The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI") defines the SapGuiAuto object.

If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx in the SAP GUI installation folder.

better. that exactly will work.

let mx = Matrix(9, 9);

function Matrix(w, h){
    let mx = Array(w);
    for(let i of mx.keys())
        mx[i] = Array(h);
    return mx;
}

what was shown

Array(9).fill(Array(9)); // Not correctly working

It does not work, because all cells are fill with one array

This is a question on Object Oriented Design, not Java the language. It's generally good practice to hide data types within the class and expose only the methods that are part of the class API. If you expose internal data types, you can never change them in the future. If you hide them, your only obligation to the user is the method's return and argument types.

function Update(key, value)
{    
    for (var i = 0; i < array.length; i++) {
        if (array[i].Key == key) {
            array[i].Value = value; 
            break;
        }
    }
}

I suggest to use the inherits helper that comes with the standard util module: http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor

There is an example of how to use it on the linked page.

You'll need to consider this in context of the application. In general, you should design an application, not a database (the database simply being part of the application).

Consider how your application should respond to various cases.

The default action is to restrict (i.e. not permit) the operation, which is normally what you want as it prevents stupid programming errors. However, on DELETE CASCADE can also be useful. It really depends on your application and how you intend to delete particular objects.

Personally, I'd use InnoDB because it doesn't trash your data (c.f. MyISAM, which does), rather than because it has FK constraints.

Try to change your label frame size height and width so your text not cut.

 [label setframe:CGRect(x,y,widht,height)];

Use:

System.Configuration.ConfigurationSettings.AppSettings["MyKey"];

AppSettings has been deprecated and is now considered obsolete (link).

In addition, the appSettings section of the app.config has been replaced by the applicationSettings section.

As someone else mentioned, you should be using System.Configuration.ConfigurationManager (link) which is new for .NET 2.0.

well, you could create the is_number function to call so your code works.

create or replace function is_number(param varchar2) return boolean
 as
   ret number;
 begin
    ret := to_number(param);
    return true;
 exception
    when others then return false;
 end;

EDIT: Please defer to Justin's answer. Forgot that little detail for a pure SQL call....

To complete André's answer, an ant solution could be like the one described in Emacs, JDEE, Ant, and the Eclipse Java Compiler, as in:

      <javac
          srcdir="${src}"
          destdir="${build.dir}/classes"> 
        <compilerarg 
           compiler="org.eclipse.jdt.core.JDTCompilerAdapter" 
           line="-warn:+unused -Xemacs"/>
        <classpath refid="compile.classpath" />
      </javac>

The compilerarg element also allows you to pass in additional command line args to the eclipse compiler.

You can find a full ant script example here which would be invoked in a command line with:

java -cp C:/eclipse-SDK-3.4-win32/eclipse/plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar org.eclipse.core.launcher.Main -data "C:\Documents and Settings\Administrator\workspace" -application org.eclipse.ant.core.antRunner -buildfile build.xml -verbose

BUT all that involves ant, which is not what Keith is after.

For a batch compilation, please refer to Compiling Java code, especially the section "Using the batch compiler"

The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into plugins/org.eclipse.jdt.core_3.4.0..jar. Since 3.2, it is also available as a separate download. The name of the file is ecj.jar.
Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). In order to use the annotations processing support, a 1.6 VM is required.

Running the batch compiler From the command line would give

java -jar org.eclipse.jdt.core_3.4.0<qualifier>.jar -classpath rt.jar A.java

or:

java -jar ecj.jar -classpath rt.jar A.java

All java compilation options are detailed in that section as well.

The difference with the Visual Studio command line compilation feature is that Eclipse does not seem to directly read its .project and .classpath in a command-line argument. You have to report all information contained in the .project and .classpath in various command-line options in order to achieve the very same compilation result.

So, then short answer is: "yes, Eclipse kind of does." ;)

I run vscode from my command line by navigating to the folder with the code and running

code .

If you do that all your bash/zsh variables are passed into vs code. You can update your .bashrc/.zshrc file or just do

export KEY=value

before opening it.

private void DeleteProductButton_Click(object sender, EventArgs e)
{


    string ProductID = deleteProductButton.Text;
    if (string.IsNullOrEmpty(ProductID))
    {
        MessageBox.Show("Please enter valid ProductID");
        deleteProductButton.Focus();
    }
    try
    {
        string SelectDelete = "Delete from Products where ProductID=" + deleteProductButton.Text;
        SqlCommand command = new SqlCommand(SelectDelete, Conn);
        command.CommandType = CommandType.Text;
        command.CommandTimeout = 15;

        DialogResult comfirmDelete = MessageBox.Show("Are you sure you want to delete this record?");
        if (comfirmDelete == DialogResult.No)
        {
            return;
        }
    }
    catch (Exception Ex)
    {
        MessageBox.Show(Ex.Message);

    }
}

This below code just show the very basic use of delegate concept .. you name the variable and class as per your requirement.

First you need to declare a protocol:

Let's call it MyFirstControllerDelegate.h

@protocol MyFirstControllerDelegate
- (void) FunctionOne: (MyDataOne*) dataOne;
- (void) FunctionTwo: (MyDatatwo*) dataTwo;
@end

Import MyFirstControllerDelegate.h file and confirm your FirstController with protocol MyFirstControllerDelegate

#import "MyFirstControllerDelegate.h"

@interface FirstController : UIViewController<MyFirstControllerDelegate>
{

}

@end

In the implementation file, you need to implement both functions of protocol:

@implementation FirstController 


    - (void) FunctionOne: (MyDataOne*) dataOne
      {
          //Put your finction code here
      }
    - (void) FunctionTwo: (MyDatatwo*) dataTwo
      {
          //Put your finction code here
      }

     //Call below function from your code
    -(void) CreateSecondController
     {
             SecondController *mySecondController = [SecondController alloc] initWithSomeData:.];
           //..... push second controller into navigation stack 
            mySecondController.delegate = self ;
            [mySecondController release];
     }

@end

in your SecondController:

@interface SecondController:<UIViewController>
{
   id <MyFirstControllerDelegate> delegate;
}

@property (nonatomic,assign)  id <MyFirstControllerDelegate> delegate;

@end

In the implementation file of SecondController.

@implementation SecondController

@synthesize delegate;
//Call below two function on self.
-(void) SendOneDataToFirstController
{
   [delegate FunctionOne:myDataOne];
}
-(void) SendSecondDataToFirstController
{
   [delegate FunctionTwo:myDataSecond];
}

@end

Here is the wiki article on delegate.

ROWS UNBOUNDED PRECEDING is no Teradata-specific syntax, it's Standard SQL. Together with the ORDER BY it defines the window on which the result is calculated.

Logically a Windowed Aggregate Function is newly calculated for each row within the PARTITION based on all ROWS between a starting row and an ending row.

Starting and ending rows might be fixed or relative to the current row based on the following keywords:

• CURRENT ROW, the current row
• UNBOUNDED PRECEDING, all rows before the current row -> fixed
• UNBOUNDED FOLLOWING, all rows after the current row -> fixed
• x PRECEDING, x rows before the current row -> relative
• y FOLLOWING, y rows after the current row -> relative

Possible kinds of calculation include:

• Both starting and ending row are fixed, the window consists of all rows of a partition, e.g. a Group Sum, i.e. aggregate plus detail rows
• One end is fixed, the other relative to current row, the number of rows increases or decreases, e.g. a Running Total, Remaining Sum
• Starting and ending row are relative to current row, the number of rows within a window is fixed, e.g. a Moving Average over n rows

So SUM(x) OVER (ORDER BY col ROWS UNBOUNDED PRECEDING) results in a Cumulative Sum or Running Total

11 -> 11
 2 -> 11 +  2                = 13
 3 -> 13 +  3 (or 11+2+3)    = 16
44 -> 16 + 44 (or 11+2+3+44) = 60

have at look at the static methods DateTime.Parse() and DateTime.TryParse(). They will allow you to pass in your date string and a format string, and get a DateTime object in return.

http://msdn.microsoft.com/en-us/library/6fw7727c.aspx

A filter argument with a trailing * can be evaluated almost instantaneously via an index lookup. A leading * implies a sequential search through the index, so it is O(N). It will take ages.

I suggest you reconsider the requirement.

You can add items / sub-items to the ListView like:

ListViewItem item = new ListViewItem(new []{"1","2","3","4"});
listView1.Items.Add(item);

But I suspect your problem is with the View Type. Set it in the designer to Details or do the following in code:

listView1.View = View.Details;

Try This.....

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load    
    Timer1.Start()
End Sub

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    Label12.Text = TimeOfDay.ToString("h:mm:ss tt")
End Sub

I've updated Bryan's code for my Sierra iMac:

# this version was tested OK vith macOs Sierra 10.12.5 (16F73) on oct 0th, 2017
# original ipa file must be store in current working directory 

IPA="ipa-filename.ipa"
PROVISION="path-to.mobileprovision"
CERTIFICATE="hexadecimal-certificate-identifier" # must be in keychain
# identifier maybe retrieved by running: security find-identity -v -p codesigning

# unzip the ipa
unzip -q "$IPA"

# remove the signature
rm -rf Payload/*.app/_CodeSignature

# replace the provision
cp "$PROVISION" Payload/*.app/embedded.mobileprovision

# generate entitlements for current app
cd Payload/
codesign -d --entitlements - *.app > entitlements.plist
cd ..
mv Payload/entitlements.plist entitlements.plist

# sign with the new certificate and entitlements
/usr/bin/codesign -f -s "$CERTIFICATE" '--entitlements' 'entitlements.plist'  Payload/*.app

# zip it back up
zip -qr resigned.ipa Payload

While I agree with what everyone has said above. I have a different take on this code. Basically you're assigning the new list to the local variable myList not the global. if you change the signature of ChangeList(List myList) to private void ChangeList() you'll see the output of 3, 4.

Here's my reasoning... Even though list is passed by reference, think of it as passing a pointer variable by value When you call ChangeList(myList) you're passing the pointer to (Global)myList. Now this is stored in the (local)myList variable. So now your (local)myList and (global)myList are pointing to the same list. Now you do a sort => it works because (local)myList is referencing the original (global)myList Next you create a new list and assign the pointer to that your (local)myList. But as soon as the function exits the (local)myList variable is destroyed. HTH

class Test
{
    List<int> myList = new List<int>();
    public void TestMethod()
    {

        myList.Add(100);
        myList.Add(50);
        myList.Add(10);

        ChangeList();

        foreach (int i in myList)
        {
            Console.WriteLine(i);
        }
    }

    private void ChangeList()
    {
        myList.Sort();

        List<int> myList2 = new List<int>();
        myList2.Add(3);
        myList2.Add(4);

        myList = myList2;
    }
}

What you asked is already answered so this is just an additional info for those who want only 2 decimal digits if optional decimal point is entered:

^\d+(\.\d{2})?$

^ : start of the string
\d : a digit (equal to [0-9])
+ : one and unlimited times

Capturing Group (.\d{2})?
? : zero and one times . : character .
\d : a digit (equal to [0-9])
{2} : exactly 2 times
$ : end of the string

1 : match
123 : match
123.00 : match
123. : no match
123.. : no match
123.0 : no match
123.000 : no match
123.00.00 : no match

JavaScript only has a Number type that stores floating point values.

There is no int.

Edit:

If you want to format the number as a string with two digits after the decimal point use:

(4).toFixed(2)

Encode your data string into JSON.

dataString = ??? ; // array?
var jsonString = JSON.stringify(dataString);
   $.ajax({
        type: "POST",
        url: "script.php",
        data: {data : jsonString}, 
        cache: false,

        success: function(){
            alert("OK");
        }
    });

In your PHP

$data = json_decode(stripslashes($_POST['data']));

  // here i would like use foreach:

  foreach($data as $d){
     echo $d;
  }

Note

When you send data via POST, it needs to be as a keyvalue pair.

Thus

data: dataString

is wrong. Instead do:

data: {data:dataString}

JAutoDoc:

an Eclipse Plugin for automatically adding Javadoc and file headers to your source code. It optionally generates initial comments from element name by using Velocity templates for Javadoc and file headers...

You need to give a relative file path of <a href="../index.html">Home</a>

Alternately you can specify a link from the root of your site with <a href="/pages/en/index.html">Home</a>

.. and . have special meanings in file paths, .. means up one directory and . means current directory.

so <a href="index.html">Home</a> is the same as <a href="./index.html">Home</a>

Easy and Fast

Import two or more csv's without having to make a list of names.

import glob

df = pd.concat(map(pd.read_csv, glob.glob('data/*.csv')))

I have been in this position, especially with new hardware. I suggest you write a little hex dump routine of your own. You will be able to see the data, and the addresses they are at, shown all together. It's good practice and a confidence builder.

The bracket stuff (e.g., [[ $a -gt $b ]] or (( $a > $b )) ) isn't enough if you want to use float numbers as well; it would report a syntax error. If you want to compare float numbers or float number to integer, you can use (( $(bc <<< "...") )).

For example,

a=2.00
b=1

if (( $(bc <<<"$a > $b") )); then 
    echo "a is greater than b"
else
    echo "a is not greater than b"
fi

You can include more than one comparison in the if statement. For example,

a=2.
b=1
c=1.0000

if (( $(bc <<<"$b == $c && $b < $a") )); then 
    echo "b is equal to c but less than a"
else
    echo "b is either not equal to c and/or not less than a"
fi

That's helpful if you want to check if a numeric variable (integer or not) is within a numeric range.

Another possibility is to select the Install Dependencies checkbox In the R package installer, on the bottom right:

From the documentation for strtotime():

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

In your date string, you have 12-16-2013. 16 isn't a valid month, and hence strtotime() returns false.

Since you can't use DateTime class, you could manually replace the - with / using str_replace() to convert the date string into a format that strtotime() understands:

$date = '2-16-2013';
echo date('Y-m-d', strtotime(str_replace('-','/', $date))); // => 2013-02-16

I discovered while following the above suggestions that for line in f: does not work for a pandas dataframe (not that anyone said it would) because the end of file in a dataframe is the last column, not the last row. for example if you have a data frame with 3 fields (columns) and 9 records (rows), the for loop will stop after the 3rd iteration, not after the 9th iteration.

This works for me on Mac:

Right click on the project, select Configure ? Convert to Maven Project.

Necroing this question but there's an explanation that no-one seems to have considered.

STATISTICS - Statistics are not available or misleading

If all of the following are true:

1. The columns feedid and feedDate are likely to be highly correlated (e.g. a feed id is more specific than a feed date and the date parameter is redundant information).
2. There is no index with both columns as sequential columns.
3. There are no manually created statistics covering both these columns.

Then sql server may be incorrectly assuming that the columns are uncorrelated, leading to lower than expected cardinality estimates for applying both restrictions and a poor execution plan being selected. The fix in this case would be to create a statistics object linking the two columns, which is not an expensive operation.

If you have setter and getter as private it will come up in PMD checks.

Try the following to get just the IP address:

Here's a function to convert js array or object into a php-compatible array to be sent as http get request parameter:

function obj2url(prefix, obj) {
        var args=new Array();
        if(typeof(obj) == 'object'){
            for(var i in obj)
                args[args.length]=any2url(prefix+'['+encodeURIComponent(i)+']', obj[i]);
        }
        else
            args[args.length]=prefix+'='+encodeURIComponent(obj);
        return args.join('&');
    }

prefix is a parameter name.

EDIT:

var a = {
    one: two,
    three: four
};

alert('/script.php?'+obj2url('a', a)); 

Will produce

/script.php?a[one]=two&a[three]=four

which will allow you to use $_GET['a'] as an array in script.php. You will need to figure your way into your favorite ajax engine on supplying the url to call script.php from js.

For example,

package main

import (
    "flag"
    "fmt"
    "os"
    "strconv"
)

func main() {
    flag.Parse()
    s := flag.Arg(0)
    // string to int
    i, err := strconv.Atoi(s)
    if err != nil {
        // handle error
        fmt.Println(err)
        os.Exit(2)
    }
    fmt.Println(s, i)
}

I made a method to solve this. My approach is:

1 - Create a abstract class that have a method to convert Objects to Array (including private attr) using Regex. 2 - Convert the returned array to json.

I use this Abstract class as parent of all my domain classes

Class code:

namespace Project\core;

abstract class AbstractEntity {
    public function getAvoidedFields() {
        return array ();
    }
    public function toArray() {
        $temp = ( array ) $this;

        $array = array ();

        foreach ( $temp as $k => $v ) {
            $k = preg_match ( '/^\x00(?:.*?)\x00(.+)/', $k, $matches ) ? $matches [1] : $k;
            if (in_array ( $k, $this->getAvoidedFields () )) {
                $array [$k] = "";
            } else {

                // if it is an object recursive call
                if (is_object ( $v ) && $v instanceof AbstractEntity) {
                    $array [$k] = $v->toArray();
                }
                // if its an array pass por each item
                if (is_array ( $v )) {

                    foreach ( $v as $key => $value ) {
                        if (is_object ( $value ) && $value instanceof AbstractEntity) {
                            $arrayReturn [$key] = $value->toArray();
                        } else {
                            $arrayReturn [$key] = $value;
                        }
                    }
                    $array [$k] = $arrayReturn;
                }
                // if it is not a array and a object return it
                if (! is_object ( $v ) && !is_array ( $v )) {
                    $array [$k] = $v;
                }
            }
        }

        return $array;
    }
}

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

Check out Oj. There are gotchas when it comes to converting any old object to JSON, but Oj can do it.

require 'oj'

class A
    def initialize a=[1,2,3], b='hello'
        @a = a
        @b = b
    end
end

a = A.new
puts Oj::dump a, :indent => 2

This outputs:

{
  "^o":"A",
  "a":[
    1,
    2,
    3
  ],
 "b":"hello"
}

Note that ^o is used to designate the object's class, and is there to aid deserialization. To omit ^o, use :compat mode:

puts Oj::dump a, :indent => 2, :mode => :compat

Output:

{
  "a":[
    1,
    2,
    3
  ],
  "b":"hello"
}

Go on using tabTextAppearance as you did but

1) to fix the capital letter side effect add textAllCap in your style :

<style name="MyTabLayoutTextAppearance" parent="TextAppearance.AppCompat.Widget.ActionBar.Title.Inverse">
    <item name="android:textSize">14sp</item>
    <item name="android:textAllCaps">true</item>
</style>

2) to fix the selected tab color side effect add in TabLayout xml the following library attributes :

app:tabSelectedTextColor="@color/color1"
app:tabTextColor="@color/color2" 

Hope this helps.

This is essentially the same thing. Use whatever you find more convenient.

Within Nano use Ctrl+O to save and Ctrl+X to exit if you were wondering

So, IN is not the same as EXISTS nor it will produce the same execution plan.

Usually EXISTS is used in a correlated subquery, that means you will JOIN the EXISTS inner query with your outer query. That will add more steps to produce a result as you need to solve the outer query joins and the inner query joins then match their where clauses to join both.

Usually IN is used without correlating the inner query with the outer query, and that can be solved in only one step (in the best case scenario).

Consider this:

1. If you use IN and the inner query result is millions of rows of distinct values, it will probably perform SLOWER than EXISTS given that the EXISTS query is performant (has the right indexes to join with the outer query).

2. If you use EXISTS and the join with your outer query is complex (takes more time to perform, no suitable indexes) it will slow the query by the number of rows in the outer table, sometimes the estimated time to complete can be in days. If the number of rows is acceptable for your given hardware, or the cardinality of data is correct (for example fewer DISTINCT values in a large data set) IN can perform faster than EXISTS.

3. All of the above will be noted when you have a fair amount of rows on each table (by fair I mean something that exceeds your CPU processing and/or ram thresholds for caching).

So the ANSWER is it DEPENDS. You can write a complex query inside IN or EXISTS, but as a rule of thumb, you should try to use IN with a limited set of distinct values and EXISTS when you have a lot of rows with a lot of distinct values.

The trick is to limit the number of rows to be scanned.

Made a category like mxcl, but this is slightly faster.

My testing shows ~15% improvement (I could be wrong, feel free to compare the two yourself).

Basically I take the portion of the array thats in front of the object and the portion behind and combine them. Thus excluding the element.

- (NSArray *)prefix_arrayByRemovingObject:(id)object 
{
    if (!object) {
        return self;
    }

    NSUInteger indexOfObject = [self indexOfObject:object];
    NSArray *firstSubArray = [self subarrayWithRange:NSMakeRange(0, indexOfObject)];
    NSArray *secondSubArray = [self subarrayWithRange:NSMakeRange(indexOfObject + 1, self.count - indexOfObject - 1)];
    NSArray *newArray = [firstSubArray arrayByAddingObjectsFromArray:secondSubArray];

    return newArray;
}

Note most of the other techniques described here break down if you're dealing with characters outside of the BMP (Unicode Basic Multilingual Plane), i.e. code points that are outside of the u0000-uFFFF range. This will only happen rarely, since the code points outside this are mostly assigned to dead languages. But there are some useful characters outside this, for example some code points used for mathematical notation, and some used to encode proper names in Chinese.

In that case your code will be:

String str = "....";
int offset = 0, strLen = str.length();
while (offset < strLen) {
  int curChar = str.codePointAt(offset);
  offset += Character.charCount(curChar);
  // do something with curChar
}

The Character.charCount(int) method requires Java 5+.

for anyone who's using react-moment:

simply use format prop to your needed format:

const now = new Date()
<Moment format="DD/MM/YYYY">{now}</Moment>

From "Find duplicate rows with PostgreSQL" here's smart solution:

To search google using API you should use Google Custom Search, scraping web page is not allowed

In java you can use CustomSearch API Client Library for Java

The maven dependency is:

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-customsearch</artifactId>
    <version>v1-rev57-1.23.0</version>
</dependency> 

Example code searching using Google CustomSearch API Client Library

public static void main(String[] args) throws GeneralSecurityException, IOException {

    String searchQuery = "test"; //The query to search
    String cx = "002845322276752338984:vxqzfa86nqc"; //Your search engine

    //Instance Customsearch
    Customsearch cs = new Customsearch.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), null) 
                   .setApplicationName("MyApplication") 
                   .setGoogleClientRequestInitializer(new CustomsearchRequestInitializer("your api key")) 
                   .build();

    //Set search parameter
    Customsearch.Cse.List list = cs.cse().list(searchQuery).setCx(cx); 

    //Execute search
    Search result = list.execute();
    if (result.getItems()!=null){
        for (Result ri : result.getItems()) {
            //Get title, link, body etc. from search
            System.out.println(ri.getTitle() + ", " + ri.getLink());
        }
    }

}

As you can see you will need to request an api key and setup an own search engine id, cx.

Note that you can search the whole web by selecting "Search entire web" on basic tab settings during setup of cx, but results will not be exactly the same as a normal browser google search.

Currently (date of answer) you get 100 api calls per day for free, then google like to share your profit.

Are you using Maven? Then you should try the AppAssembler Plugin:

The Application Assembler Plugin is a Maven plugin for generating scripts for starting java applications. ... All artifacts (dependencies + the artifact from the project) are added to the classpath in the generated bin scripts.

Supported platforms:

Unix-variants

Windows NT (Windows 9x is NOT supported)

Java Service Wrapper (JSW)

For mac users (HighSierra), do not install node using brew. It'll mess up with npm. I had to uninstall node and install using the package in the main nodejs.org source : https://nodejs.org/en/

Here's a simple guide that doesn't use brew: https://coolestguidesontheplanet.com/installing-node-js-on-macos/

As gratitude to the timely help I got from here - a minor update to above.

$query = "UPDATE `db`.`table` SET `fieldname`=  str_to_date(  fieldname, '%d/%m/%Y')";

You can and should never assume that $_SERVER['HTTP_REFERER'] will be present.

If you control the previous page, you can pass the URL as a parameter "site.com/page2.php?prevUrl=".urlencode("site.com/page1.php").

If you don't control the page, then there is nothing you can do.

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

You don't need to write a converter, just do this in your handler/codebehind:

int i = Convert.ToInt32(txtMyTextBox.Text);

OR

int i = int.Parse(txtMyTextBox.Text);

The Text property of your textbox is a String type, so you have to perform the conversion in the code.

Generally, this isn't a great idea. Taking your scenario, if you had evil intentions, you could hide everything underneath your "overlay". Then, when a user clicks on a link they think should take them to bankofamerica.com, instead it triggers the hidden link which takes them to myevilsite.com.

That said, event bubbling works, and if it's within an application, it's not a big deal. The following code is an example. Clicking the blue area pops up an alert, even though the alert is set on the red area. Note that the orange area does NOT work, because the event will propagate through the PARENT elements, so your overlay needs to be inside whatever element you're observing the clicks on. In your scenario, you may be out of luck.

<html>
<head>
</head>
<body>
    <div id="outer" style="position:absolute;height:50px;width:60px;z-index:1;background-color:red;top:5px;left:5px;" onclick="alert('outer')"> 
        <div id="nested" style="position:absolute;height:50px;width:60px;z-index:2;background-color:blue;top:15px;left:15px;">
        </div>
    </div>
    <div id="separate" style="position:absolute;height:50px;width:60px;z-index:3;background-color:orange;top:25px;left:25px;">
    </div>
</body>
</html>

you can get textarea data by name and id

// by name
<textarea name="comment"></textarea>
let text_area_data = $('textarea[name="comment"]').val();

// by id
<textarea id="comment" name="comment"></textarea>
let text_area_data = $('textarea#comment').val();

The TimeSpan constructor allows you to pass in seconds. Simply declare a variable of type TimeSpan amount of seconds. Ex:

TimeSpan span = new TimeSpan(0, 0, 500);
span.ToString();

Use:

import color

class Color(color.Color):
    ...

If this were Python 2.x, you would also want to derive color.Color from object, to make it a new-style class:

class Color(object):
    ...

This is not necessary in Python 3.x.

Just use

WHERE RAND() < 0.1 

to get 10% of the records or

WHERE RAND() < 0.01 

to get 1% of the records, etc.

Follow this link for solution: Android Lint contentDescription warning

Resolved this warning by setting attribute android:contentDescription for my ImageView

android:contentDescription="@string/desc"

Android Lint support in ADT 16 throws this warning to ensure that image widgets provide a contentDescription

This defines text that briefly describes the content of the view. This property is used primarily for accessibility. Since some views do not have textual representation this attribute can be used for providing such.

Non-textual widgets like ImageViews and ImageButtons should use the contentDescription attribute to specify a textual description of the widget such that screen readers and other accessibility tools can adequately describe the user interface.

This link for explanation: Accessibility, It's Impact and Development Resources

Many Android users have disabilities that require them to interact with their Android devices in different ways. These include users who have visual, physical or age-related disabilities that prevent them from fully seeing or using a touchscreen.

Android provides accessibility features and services for helping these users navigate their devices more easily, including text-to-speech, haptic feedback, trackball and D-pad navigation that augments their experience. Android application developers can take advantage of these services to make their applications more accessible and also build their own accessibility services.

This guide is for making your app accessible: Making Apps More Accessible

Making sure your application is accessible to all users is relatively easy, particularly when you use framework-provided user interface components. If you only use these standard components for your application, there are just a few steps required to ensure your application is accessible:

1. Label your ImageButton, ImageView, EditText, CheckBox and other user interface controls using the android:contentDescription attribute.

2. Make all of your user interface elements accessible with a directional controller, such as a trackball or D-pad.

3. Test your application by turning on accessibility services like TalkBack and Explore by Touch, and try using your application using only directional controls.

Creating a table and copying the data in a single command:

create table T_NEW as
  select * from T;

* This will not copy PKs, FKs, Triggers, etc.

I adopted @RobW's nice answer to get it working on Mac OS X 10.8. Other versions of Mac OS X may probably work too.

The little extra work is actually only needed to keep your original Google Chrome user settings and the old version separated.

1. Download another version of Google Chrome, like the Dev channel and extract the .app file

2. (optional) Rename it to Google Chrome X.app – if not already different from Google Chrome.app

(Be sure to replace X for all following steps with the actual version of Chrome you just downloaded)

3. Move Google Chrome X.app to /Applications without overwritting your current Chrome

4. Open the Terminal, create a shell script and make your script executable:

   cd /Applications
   touch google-chrome-version-start.sh
   chmod +x google-chrome-version-start.sh
   nano google-chrome-version-start.sh
   

5. Modify the following code according to the version you downloaded and paste it into the script

   #!/usr/bin/env bash
   /Applications/Google\ Chrome\ X.app/Contents/MacOS/Google\ Chrome\ X --user-data-dir="tmp/Google Chrome/X/" & disown
   

   For example for Dev Channel:

   #!/usr/bin/env bash
   /Applications/Google\ Chrome\ Dev.app/Contents/MacOS/Google\ Chrome\ Dev --user-data-dir="tmp/Google Chrome Dev/" & disown
   

   (This will store Chrome's data at ~/tmp/Google Chrome/VERSION/. For more explanations see the original answer.)

6. Now execute the script and be happy!

   /Application/google-chrome-version-start.sh
   

Tested it with Google Chrome 88 on a Mac running OS X 10.15 Catalina

I had the same error, the problem was because I no longer had disk space. to check the space run this:

$ df -h

Then delete some files that you didn't need.

After this commands:

service mysql start
systemctl status mysql.service
mysql -u root -p

After entering with the root password verify that the mysql service was active

I'm surprised nobody mentioned this. You can tether via Bluetooth, and separate them by ten+ meters(or less with obstacles). You've got a real bad connection. No microwave, no elevator, no software needed.

Insertion:

INSERT INTO ... VALUES ('bob', MD5('bobspassword'));

retrieval:

SELECT ... FROM ... WHERE ... AND password=md5('hopefullybobspassword');

is how'd you'd do it directly in the queries. However, if your MySQL has query logging enabled, then the passwords' plaintext will get written out to this log. So... you'd want to do the MD5 conversion in your script, and then insert that resulting hash into the query.

You are missing 'json' dataType in the $.post() method:

$.post('http://www.example.com:PORT_NUMBER/MYSERVLET',{MyParam: 'value'})
        .done(function(data){
                  alert(data);
         }, "json");
         //-^^^^^^-------here

Updates:

try with this:

response.setHeader("Access-Control-Allow-Origin", request.getHeader("Origin"));

find builds a list of files. It applies the predicate you supplied to each one and returns those that pass.

This idea that -prune means exclude from results was really confusing for me. You can exclude a file without prune:

find -name 'bad_guy' -o -name 'good_guy' -print  // good_guy

All -prune does is alter the behavior of the search. If the current match is a directory, it says "hey find, that file you just matched, dont descend into it". It just removes that tree (but not the file itself) from the list of files to search.

It should be named -dont-descend.

Why not use TOP X?

SELECT pass1.* FROM 
 (SELECT TOP 2000000 tblA.ID, tblA.CustomerName 
  FROM TABLE_A AS tblA ORDER BY 2) AS pass1
UNION ALL 
SELECT pass2.* FROM 
  (SELECT TOP 2000000 tblB.ID, tblB.CustomerName 
   FROM TABLE_B AS tblB ORDER BY 2) AS pass2

The TOP 2000000 is an arbitrary number, that is big enough to capture all of the data. Adjust as per your requirements.

You can try the following tutorial, it may help you to move forward:

Serving React and Django together

If you transferred these files through disk or other means, it is likely they were not saved properly.

Just Add these 2 permissions

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

in your app's AndroidManifest.xml

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.example.android.networkusage"
        ...>
    
    
        <uses-permission android:name="android.permission.INTERNET" />
        <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    
        <application 
            ...>
            ...
        </application>
    </manifest>

Happy Coding:)

For me a simple

works. This is from within the screen session.

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

For flexibility and other places you might want to validated. You can use the following function.

`function validateOnlyTextField(element) {
    var str = element.value;
    if(!(/^[a-zA-Z, ]+$/.test(str))){
        // console.log('String contain number characters');
        str = str.substr(0,  str.length -1);
        element.value = str;
    }
}`

Then on your html section use the following event.

<input type="text" id="names" onkeyup="validateOnlyTextField(this)" />

You can always reuse the function.

I have something different stuff for you which is easy and effective.

    <style> 
    .case-after:after { // set your properties here like eg: 
        color:#3fd309 !important; 
     } 
     .case-before:before { // set your properties here like eg: 
        color:#151715 !important; 
     }
 </style>
  // case for after
    $('#button-id').on('click', function() {
        $(".target-div").toggleClass('case-after');
    });

     // case for before
    $('#button-id').on('click', function() {
        $(".target-div").toggleClass('case-before');
    });

I can not add comment as of now so adding this as an answer.

@Andy's answer is good and the same results can be achieved with the following line of code:

tableView.tableFooterView = [UIView new];

'new' method belongs to NSObject class and invokes alloc and init methods for UIView.

You shouldn't overload the templates with complex logic, it's a bad practice. Remember to always keep it simple!

The better approach would be to extract this logic into reusable function on your $rootScope:

.run(function ($rootScope) {
  $rootScope.inArray = function (item, array) {
    return (-1 !== array.indexOf(item));
  };
})

Then, use it in your template:

<li ng-class="{approved: inArray(jobSet, selectedForApproval)}"></li>

I think everyone will agree that this example is much more readable and maintainable.

A simple solution is to create your own subclass of ViewPager that has a private boolean flag, isPagingEnabled. Then override the onTouchEvent and onInterceptTouchEvent methods. If isPagingEnabled equals true invoke the super method, otherwise return.

public class CustomViewPager extends ViewPager {

    private boolean isPagingEnabled = true;

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

    public CustomViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onTouchEvent(event);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent event) {
        return this.isPagingEnabled && super.onInterceptTouchEvent(event);
    }

    public void setPagingEnabled(boolean b) {
        this.isPagingEnabled = b;
    }
}

Then in your Layout.XML file replace any <com.android.support.V4.ViewPager> tags with <com.yourpackage.CustomViewPager> tags.

This code was adapted from this blog post.

The original code you suggest is the best way.

Matlab is extremely good at vectorized operations such as this, at least for large vectors.

The built-in norm function is very fast. Here are some timing results:

V = rand(10000000,1);
% Run once
tic; V1=V/norm(V); toc           % result:  0.228273s
tic; V2=V/sqrt(sum(V.*V)); toc   % result:  0.325161s
tic; V1=V/norm(V); toc           % result:  0.218892s

V1 is calculated a second time here just to make sure there are no important cache penalties on the first call.

Timing information here was produced with R2008a x64 on Windows.

EDIT:

Revised answer based on gnovice's suggestions (see comments). Matrix math (barely) wins:

clc; clear all;
V = rand(1024*1024*32,1);
N = 10;
tic; for i=1:N, V1 = V/norm(V);         end; toc % 6.3 s
tic; for i=1:N, V2 = V/sqrt(sum(V.*V)); end; toc % 9.3 s
tic; for i=1:N, V3 = V/sqrt(V'*V);      end; toc % 6.2 s ***
tic; for i=1:N, V4 = V/sqrt(sum(V.^2)); end; toc % 9.2 s
tic; for i=1:N, V1=V/norm(V);           end; toc % 6.4 s

IMHO, the difference between "norm(V)" and "sqrt(V'*V)" is small enough that for most programs, it's best to go with the one that's more clear. To me, "norm(V)" is clearer and easier to read, but "sqrt(V'*V)" is still idiomatic in Matlab.

I've been searching answer but couldn't find but finally I could fix this by adding play-service-ads dependency let's try this

You are storing 135.69 as String in currency. But instead of passing variable currency, you are again passing 135.69(double value) into new BigDecimal(). So you are seeing a lot of numbers in the output. If you pass the currency variable, your output will be 135.69

I had to use required="required" along with the same name and type, and then validation worked fine.

<input type="radio" name="user-radio"  id="" value="User" required="required" />

<input type="radio" name="user-radio" id="" value="Admin" />

<input type="radio" name="user-radio" id="" value="Guest" /> 

Use ROW_NUMBER() instead. ROWNUM is a pseudocolumn and ROW_NUMBER() is a function. You can read about difference between them and see the difference in output of below queries:

SELECT * FROM (SELECT rownum, deptno, ename
           FROM scott.emp
        ORDER BY deptno
       )
 WHERE rownum <= 3
 /

ROWNUM    DEPTNO    ENAME
---------------------------
 7        10    CLARK
 14       10    MILLER
 9        10    KING


 SELECT * FROM 
 (
  SELECT deptno, ename
       , ROW_NUMBER() OVER (ORDER BY deptno) rno
  FROM scott.emp
 ORDER BY deptno
 )
WHERE rno <= 3
/

DEPTNO    ENAME    RNO
-------------------------
10    CLARK        1
10    MILLER       2
10    KING         3

I normally differentiate these two via this diagram:

Use PrimaryKeyJoinColumn

Use JoinColumn

ActiveXObject is non-standard and only supported by Internet Explorer on Windows.

There is no native cross browser way to write to the file system without using plugins, even the draft File API gives read only access.

If you want to work cross platform, then you need to look at such things as signed Java applets (keeping in mind that that will only work on platforms for which the Java runtime is available).

List<Card> list = new ArrayList<Card>(Arrays.asList(hand));

If insert trigger is too expensive to use, but a delete trigger could be afforded, and there is an auto-increment id, then after counting entire table once, and remembering the count as last-count and the last-counted-id,

then each day just need to count for id > last-counted-id, add that to last-count, and store the new last-counted-id.

The delete trigger would decrement last-count, if id of deleted record <= last-counted-id.

You are doing mistake in "configuration_page.jsp" file. here in this file , function loadXMLDoc() 's line number 2 should be like this:

var config=document.getElementsByName('configselect').value;

because you have declared only the name attribute in your <select> tag. So you should get this element by name.

After correcting this, it will run without any JavaScript error

Here is a theoretical answer. That can be found here

A { get set } property cannot be a constant stored property. It should be a computed property and both get and set should be implemented.

git reset --soft is just for that: it is like git reset --hard, but doesn't touch the files.

To elaborate on what @Raynos said, the function you have defined is an asynchronous callback. It doesn't execute right away, rather it executes when the file loading has completed. When you call readFile, control is returned immediately and the next line of code is executed. So when you call console.log, your callback has not yet been invoked, and this content has not yet been set. Welcome to asynchronous programming.

Example approaches

const fs = require('fs');
// First I want to read the file
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    const content = data;

    // Invoke the next step here however you like
    console.log(content);   // Put all of the code here (not the best solution)
    processFile(content);   // Or put the next step in a function and invoke it
});

function processFile(content) {
    console.log(content);
}

Or better yet, as Raynos example shows, wrap your call in a function and pass in your own callbacks. (Apparently this is better practice) I think getting into the habit of wrapping your async calls in function that takes a callback will save you a lot of trouble and messy code.

function doSomething (callback) {
    // any async callback invokes callback with response
}

doSomething (function doSomethingAfter(err, result) {
    // process the async result
});

It's possible to remove the workspace in Eclipse without much complications. The options are available under Preferences->General->Startup and Shutdown->Workspaces.

Note that this does not actually delete the files from the system, it simply removes it from the list of suggested workspaces. It changes the org.eclipse.ui.ide.prefs file in Jon's answer from within Eclipse.

I generally try to avoid expressions with ng-show and ng-hide as they were designed as booleans, not conditionals. If I need both conditional and boolean logic, I prefer to put in the conditional logic using ng-if as the first check, then add in an additional check for the boolean logic with ng-show and ng-hide

Howerver, if you want to use a conditional for ng-show or ng-hide, here is a link with some examples: Conditional Display using ng-if, ng-show, ng-hide, ng-include, ng-switch

def to_str(key, value):
    if isinstance(key, unicode):
        key = str(key)
    if isinstance(value, unicode):
        value = str(value)
    return key, value

pass key and value to it, and add recursion to your code to account for inner dictionary.

For a Swift implementation, you can add this as a UIView extension.

extension UIView {

    struct Constants {
        static let ExternalBorderName = "externalBorder"
    }

    func addExternalBorder(borderWidth: CGFloat = 2.0, borderColor: UIColor = UIColor.whiteColor()) -> CALayer {
        let externalBorder = CALayer()
        externalBorder.frame = CGRectMake(-borderWidth, -borderWidth, frame.size.width + 2 * borderWidth, frame.size.height + 2 * borderWidth)
        externalBorder.borderColor = borderColor.CGColor
        externalBorder.borderWidth = borderWidth
        externalBorder.name = Constants.ExternalBorderName

        layer.insertSublayer(externalBorder, atIndex: 0)
        layer.masksToBounds = false

        return externalBorder
    }

    func removeExternalBorders() {
        layer.sublayers?.filter() { $0.name == Constants.ExternalBorderName }.forEach() {
            $0.removeFromSuperlayer()
        }
    }

    func removeExternalBorder(externalBorder: CALayer) {
        guard externalBorder.name == Constants.ExternalBorderName else { return }
        externalBorder.removeFromSuperlayer()
    }

}

Actually - Patrick's code sort of worked for me as well. The correct way to do it would be along the lines of this:

Note: there's a bit of jquery ahead:

if ($.browser.msie == false) {
    var h = (document.getElementById("iframeID").contentDocument.body.offsetHeight);
} else {
    var h = (document.getElementById("iframeID").Document.body.scrollHeight);
}

A quick trick to use for me is using the find duplicates query SQL and changing 1 to 0 in Having expression. Like this:

SELECT COUNT([UniqueField]) AS DistinctCNT FROM
(
  SELECT First([FieldName]) AS [UniqueField]
  FROM TableName
  GROUP BY [FieldName]
  HAVING (((Count([FieldName]))>0))
);

Hope this helps, not the best way I am sure, and Access should have had this built in.

This is the best answer. Shorthand (background) is for reset and DRY (combine with longhand).

var my_object = { a:undefined, b:2, c:4, d:undefined };

var newObject = _.reject(my_collection, function(val){ return _.isUndefined(val) })

//--> newCollection = { b: 2, c: 4 }

Perhaps the pandas interface has changed since @Rutger answered, but in the version I'm using (0.15.2), the date_parser function receives a list of dates instead of a single value. In this case, his code should be updated like so:

dateparse = lambda dates: [pd.datetime.strptime(d, '%Y-%m-%d %H:%M:%S') for d in dates]

df = pd.read_csv(infile, parse_dates=['datetime'], date_parser=dateparse)

printf is great, but people forget about it.

$ for num in 1 10 100 1000 10000 100000 1000000; do printf "%10s %s\n" $num "foobar"; done
         1 foobar
        10 foobar
       100 foobar
      1000 foobar
     10000 foobar
    100000 foobar
   1000000 foobar

$ for((i=0;i<array_size;i++));
do
    printf "%10s %10d %10s" stringarray[$i] numberarray[$i] anotherfieldarray[%i]
done

Notice I used %10s for strings. %s is the important part. It tells it to use a string. The 10 in the middle says how many columns it is to be. %d is for numerics (digits).

man 1 printf for more info.

1.2975118E7 is scientific notation.

1.2975118E7 = 1.2975118 * 10^7 = 12975118

Also, Math.round(f) returns an integer. You can't use it to get your desired format x.xx.

You could use String.format.

Tried and working. you are using,

<textarea name='Status'> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>

I am using javascript , (don't know about php), use id ="status" in textarea like

<textarea name='Status' id="status"> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>

then make a call to servlet sending the status to backend for updating using whatever strutucre(like MVC in java or anyother) you like, like this in your UI in script tag

<srcipt>
function UpdateStatus(){

//make an ajax call and get status value using the same 'id'
var var1= document.getElementById("status").value;
$.ajax({

        type:"GET",//or POST
        url:'http://localhost:7080/ajaxforjson/Testajax',
                           //  (or whatever your url is)
        data:{data1:var1},
        //can send multipledata like {data1:var1,data2:var2,data3:var3
        //can use dataType:'text/html' or 'json' if response type expected 
        success:function(responsedata){
               // process on data
               alert("got response as "+"'"+responsedata+"'");

        }
     })

}
</script>

and jsp is like

the servlet will look like:   //webservlet("/zcvdzv") is just for url annotation
@WebServlet("/Testajax")

public class Testajax extends HttpServlet {
private static final long serialVersionUID = 1L;
public Testajax() {
    super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    String data1=request.getParameter("data1");
    //do processing on datas pass in other java class to add to DB
    // i am adding or concatenate
    String data="i Got : "+"'"+data1+"' ";
    System.out.println(" data1 : "+data1+"\n data "+data);
    response.getWriter().write(data);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
    doGet(request, response);
}

}

If you've been doing unit testing for a decent amount of time, I see no reason for it not to be approaching 95%+. However, at a minimum, I've always worked with 80%, even when new to testing.

This number should only include code written in the project (excludes frameworks, plugins, etc.) and maybe even exclude certain classes composed entirely of code written of calls to outside code. This sort of call should be mocked/stubbed.

The answers that have no less that 2739 upvotes by now are misleading and incorrect.

The question is: "How do you empty your existing array?" E.g. for A = [1,2,3,4].

1. Saying "A = [] is the answer" is ignorant and absolutely incorrect. [] == [] is false.

   This is because these two arrays are two separate, individual objects, with their own two identities, taking up their own space in the digital world, each on its own.

Let's say your mother asks you to empty the trash can.

• You don't bring in a new one as if you've done what you've been asked for.
• Instead, you empty the trash can.
• You don't replace the filled one with a new empty can, and you don't take the label "A" from the filled can and stick it to the new one as in A = [1,2,3,4]; A = [];

Emptying an array object is the easiest thing ever:

A.length = 0;

This way, the can under "A" is not only empty, but also as clean as new!

2. Furthermore, you are not required to remove the trash by hand until the can is empty! You were asked to empty the existing one, completely, in one turn, not to pick up the trash until the can gets empty, as in:

   while(A.length > 0) {
       A.pop();
   }
   

3. Nor, to put your left hand at the bottom of the trash, holding it with your right at the top to be able to pull its content out as in:

   A.splice(0, A.length);
   

No, you were asked to empty it:

A.length = 0;

This is the only code that correctly empties the contents of a given JavaScript array.

A generic solution which translates any json list of flat objects to csv.

Pass the input.json file as first argument on command line.

import csv, json, sys

input = open(sys.argv[1])
data = json.load(input)
input.close()

output = csv.writer(sys.stdout)

output.writerow(data[0].keys())  # header row

for row in data:
    output.writerow(row.values())

I struggled with all the answers here, starting with Pascal's solution, which is getting harder with the Java compiler not binding against rt.jar by default any more (and using internal classes makes it specific to that runtime implementation).

The answer from edubriguenti brought me close. The way the handler is hooked up in the final bit of code didn't work for me, though - it was never called.

I ended up using a variation of his handler class, but wired it into the javax.xml.ws.Service instance like this:

Service service = Service.create(url, qname); service.setHandlerResolver( portInfo -> Collections.singletonList(new SOAPHeaderHandler(handlerArgs)) );

You can get result distinct by two columns use below SQL:

SELECT COUNT(*) FROM (SELECT DISTINCT c1, c2 FROM [TableEntity]) TE

After getting some inspiration from Orr Sella's blog post I wrote a pre-commit hook (resides in ~/.git/templates/hooks) which would set specific usernames and e-mail addresses based on the information inside a local repositorie's ./.git/config:

You have to place the path to the template directory into your ~/.gitconfig:

[init]
    templatedir = ~/.git/templates

Then each git init or git clone will pick up that hook and will apply the user data during the next git commit. If you want to apply the hook to already exisiting repos then just run a git init inside the repo in order to reinitialize it.

Here is the hook I came up with (it still needs some polishing - suggestions are welcome). Save it either as

~/.git/templates/hooks/pre_commit

or

~/.git/templates/hooks/post-checkout

and make sure it is executable: chmod +x ./post-checkout || chmod +x ./pre_commit

EDIT:

So I rewrote the hook as a hook and command in Python. Additionally it's possible to call the script as a Git command (git passport), too. Also it's possible to define an arbitrary number of IDs inside a configfile (~/.gitpassport) which are selectable on a prompt. You can find the project at github.com: git-passport - A Git command and hook written in Python to manage multiple Git accounts / user identities.

Your best bet is probably waitForCondition and writing a javascript function that returns true when the map is loaded.

For anyone who must work with an older version of MySQL (pre-5.0 ish) you are unable to do sub-queries for this type of query. Here is the solution I was able to do and it seemed to work great.

SELECT MAX(d.id), d2.*, CONCAT(title,' ',forename,' ',surname) AS name
FROM customer AS c 
LEFT JOIN customer_data as d ON c.customer_id=d.customer_id 
LEFT JOIN customer_data as d2 ON d.id=d2.id
WHERE CONCAT(title, ' ', forename, ' ', surname) LIKE '%Smith%'
GROUP BY c.customer_id LIMIT 10, 20;

Essentially this is finding the max id of your data table joining it to the customer then joining the data table to the max id found. The reason for this is because selecting the max of a group doesn't guarantee that the rest of the data matches with the id unless you join it back onto itself.

I haven't tested this on newer versions of MySQL but it works on 4.0.30.

var Is = {
    character: {
        number: (function() {
            // Only computed once
            var zero = "0".charCodeAt(0), nine = "9".charCodeAt(0);

            return function(c) {
                return (c = c.charCodeAt(0)) >= zero && c <= nine;
            }
        })()
    }
};

For Python 3 and above,To select first n Pairs

n=4
firstNpairs = {k: Diction[k] for k in list(Diction.keys())[:n]}

You are setting it't type as submit. That means that browser should post your <form> data to the server.

In fact a tag has no type attribute according to w3schools.

So remote type attribute and it should work for you.

Some time This Code Not worked proper

Same-origin policy

https://en.wikipedia.org/wiki/Same-origin_policy

https://en.wikipedia.org/wiki/Cross-origin_resource_sharing

problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1]. 

Ref : https://superuser.com/questions/773719/how-do-all-of-these-save-video-from-youtube-services-work/773998#773998

url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts              // DASH: contains video or audio stream

Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this

url  // direct HTTP link to a video
itag // code specifying the quality
s    // signature, security measure to counter downloading

Each URL will be encoded so you will need to decode them. Now the tricky part.

YouTube has at least 3 security levels for their videos

unsecured // as expected, you can download these with just the unencoded URL
s         // see below
RTMPE     // uses "rtmpe://" protocol, no known method for these

The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.

The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as

AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this

function mo(a) {
  a = a.split("");
  a = lo.rw(a, 1);
  a = lo.rw(a, 32);
  a = lo.IC(a, 1);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 77);
  a = lo.IC(a, 3);
  a = lo.wS(a, 44);
  return a.join("")
}

This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as

http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js

this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header

Access-Control-Allow-Origin: http://www.youtube.com

and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests

Access-Control-Allow-Origin: *

So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.

Use local-web-server npm package.

https://www.npmjs.com/package/local-web-server

$ npm install -g local-web-server
$ cd <your-app-folder>
$ ws

Also, you can run

$ ws -p 8181

-p defines the port you want to use

After that, just go to your browser and access http:localhost:8181/

Yes, they are very different in theory, and in implementation.

Lexers are used to recognize "words" that make up language elements, because the structure of such words is generally simple. Regular expressions are extremely good at handling this simpler structure, and there are very high-performance regular-expression matching engines used to implement lexers.

Parsers are used to recognize "structure" of a language phrases. Such structure is generally far beyond what "regular expressions" can recognize, so one needs "context sensitive" parsers to extract such structure. Context-sensitive parsers are hard to build, so the engineering compromise is to use "context-free" grammars and add hacks to the parsers ("symbol tables", etc.) to handle the context-sensitive part.

Neither lexing nor parsing technology is likely to go away soon.

They may be unified by deciding to use "parsing" technology to recognize "words", as is currently explored by so-called scannerless GLR parsers. That has a runtime cost, as you are applying more general machinery to what is often a problem that doesn't need it, and usually you pay for that in overhead. Where you have lots of free cycles, that overhead may not matter. If you process a lot of text, then the overhead does matter and classical regular expression parsers will continue to be used.

Try This

Write code in your service

import {Observable, of} from 'rxjs';

import json file

import Product  from "./database/product.json";

getProduct(): Observable<any> {
   return of(Product).pipe(delay(1000));
}

In component

get_products(){
    this.sharedService.getProduct().subscribe(res=>{
        console.log(res);
    })        
}

I can see you said you didn't want to use mysqldump, but I reached this page while looking for a similar solution and others might find it as well. With that in mind, here is a simple way to duplicate a database from the command line of a windows server:

1. Create the target database using MySQLAdmin or your preferred method. In this example, db2 is the target database, where the source database db1 will be copied.
2. Execute the following statement on a command line:

mysqldump -h [server] -u [user] -p[password] db1 | mysql -h [server] -u [user] -p[password] db2

Note: There is NO space between -p and [password]

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

Tested answer:

In the .view-row css, change:

display:table-row;

to:

display:table

and get rid of "float". Everything will work as expected.

As it has been suggested in the comments, there is no need for a wrapping table. CSS allows for omitting levels of the tree structure (in this case rows) that are implicit. The reason your code doesn't work is that "width" can only be interpreted at the table level, not at the table-row level. When you have a "table" and then "table-cell"s directly underneath, they're implicitly interpreted as sitting in a row.

Working example:

<div class="view">
    <div>Type</div>
    <div>Name</div>                
</div>

with css:

.view {
  width:100%;
  display:table;
}

.view > div {
  width:50%;
  display: table-cell;
}

Watch out for other paths ending in \ too. I had this:

...bin;C:\Program Files\Microsoft\Web Platform Installer\;C:\Program Files\nodejs\

and changed it to this:

bin;C:\Program Files\Microsoft\Web Platform Installer\;C:\Program Files\nodejs

removing the final \, but it still didn't work. The previous path, for the Web Platform Installer, had a trailing \ too. Removing that fixed the problem.

Here's an update for modern browsers in 2019

let playerSpriteX = 0;_x000D_
_x000D_
document.addEventListener('keyup', (e) => {_x000D_
  if (e.code === "ArrowUp")        playerSpriteX += 10_x000D_
  else if (e.code === "ArrowDown") playerSpriteX -= 10_x000D_
_x000D_
  document.getElementById('test').innerHTML = 'playerSpriteX = ' + playerSpriteX;_x000D_
});

Click on this window to focus it, and hit keys up and down_x000D_
<br><br><br>_x000D_
<div id="test">playerSpriteX = 0</div>

Original answer from 2013

window.onkeyup = function(e) {
   var key = e.keyCode ? e.keyCode : e.which;

   if (key == 38) {
       playerSpriteX += 10;
   }else if (key == 40) {
       playerSpriteX -= 10;
   }
}

FIDDLE

Use the values attribute to return the values as a np array and then use [0] to get the first value:

In [4]:
df.loc[df.Letters=='C','Letters'].values[0]

Out[4]:
'C'

EDIT

I personally prefer to access the columns using subscript operators:

df.loc[df['Letters'] == 'C', 'Letters'].values[0]

This avoids issues where the column names can have spaces or dashes - which mean that accessing using ..

Look this:

List<Client> result = clients
    .stream()
    .filter(c -> 
        (users.stream().map(User::getName).collect(Collectors.toList())).contains(c.getName()))
        .collect(Collectors.toList());

For those interested, here's an alternative to invoking Array.join:

var arrayOfStrings = ['foo', 'bar'];
var result = String.concat.apply(null, arrayOfStrings);
console.log(result);

The output, as expected, is the string 'foobar'. In Firefox, this approach outperforms Array.join but is outperformed by + concatenation. Since String.concat requires each segment to be specified as a separate argument, the caller is limited by any argument count limit imposed by the executing JavaScript engine. Take a look at the documentation of Function.prototype.apply() for more information.

Since Java 7 you can use java.util.Objects.equals(Object a, Object b):

These utilities include null-safe or null-tolerant methods

Long id1 = null;
Long id2 = 0l;
Objects.equals(id1, id2));

Remembering that the mean can also by obtained using a linear model, regressing the variable against a single intercept, you can use also the lm(x~1) function for this!

Advantages are:

• You obtain immediately confidence intervals with confint()
• You can use tests for various hypothesis about the mean, using for example car::linear.hypothesis()
• You can use more sophisticated estimates of the standard deviation, in case you have some heteroskedasticity, clustered-data, spatial-data etc, see package sandwich

## generate data
x <- rnorm(1000)

## estimate reg
reg <- lm(x~1)
coef(summary(reg))[,"Std. Error"]
#> [1] 0.03237811

## conpare with simple formula
all.equal(sd(x)/sqrt(length(x)),
          coef(summary(reg))[,"Std. Error"])
#> [1] TRUE

## extract confidence interval
confint(reg)
#>                   2.5 %    97.5 %
#> (Intercept) -0.06457031 0.0625035

Your code attempts to overwrite a string literal. This is undefined behaviour.

There are several ways to fix this:

1. use malloc() then strcpy() then free();
2. turn str into an array and use strcpy();
3. use strdup().

Make sure you XML looks like this:

<?xml version="1.0" encoding="utf-8"?>

...
</rootElement>

Also, a blank XML file will return the same Root elements is missing exception. Each XML file must have a root element / node which encloses all the other elements.

Runescape by Jagex is written in Java, the "video game" tag might not specifically apply it being an on-line game, but it does have a decent following.

Understand that .children is a property of an Element. ¹ Only Elements have .children, and these children are all of type Element. ²

However, .childNodes is a property of Node. .childNodes can contain any node. ³

A concrete example would be:

let el = document.createElement("div");
el.textContent = "foo";

el.childNodes.length === 1; // Contains a Text node child.
el.children.length === 0;   // No Element children.

Most of the time, you want to use .children because generally you don't want to loop over Text or Comment nodes in your DOM manipulation.

If you do want to manipulate Text nodes, you probably want .textContent instead. ⁴

<sup>1. Technically, it is an attribute of ParentNode, a mixin included by Element.
2. They are all elements because .children is a HTMLCollection, which can only contain elements.
3. Similarly, .childNodes can hold any node because it is a NodeList.
4. Or .innerText. See the differences here or here.</sup>

For completeness and correct resource management:

        ICursor cursor = null;
        try
        {

            cursor = db.RawQuery("SELECT * FROM " + RECORDS_TABLE + " WHERE " + RECORD_ID + "=?", new String[] { id + "" });

            if (cursor.Count > 0)
            {
                cursor.MoveToFirst();
            }
            return GetRecordFromCursor(cursor); // Copy cursor props to custom obj
        }
        finally // IMPORTANT !!! Ensure cursor is not left hanging around ...
        {
            if(cursor != null)
                cursor.Close();
        }

Well I know this maybe rather dumb than and simple, but I think it should work:

string n;
cin>> n;
char b[200];
for (int i = 0; i < sizeof(n); i++)
{
    b[i] = n[i];
    cout<< b[i]<< " ";
}

You can find current locks on your table by following query.

USE yourdatabase;
GO

SELECT * FROM sys.dm_tran_locks
  WHERE resource_database_id = DB_ID()
  AND resource_associated_entity_id = OBJECT_ID(N'dbo.yourtablename');

See sys.dm_tran_locks

If multiple instances of the same request_owner_type exist, the request_owner_id column is used to distinguish each instance. For distributed transactions, the request_owner_type and the request_owner_guid columns will show the different entity information.

For example, Session S1 owns a shared lock on Table1; and transaction T1, which is running under session S1, also owns a shared lock on Table1. In this case, the resource_description column that is returned by sys.dm_tran_locks will show two instances of the same resource. The request_owner_type column will show one instance as a session and the other as a transaction. Also, the resource_owner_id column will have different values.

A session is stored server side, you can't modify it with JavaScript. Sessions may contain sensitive data.

You can modify cookies using document.cookie.

You can easily find many examples how to modify cookies.

This is 2 step process

• git checkout BranchB ( destination branch is BranchB, so we need the head on this branch)
• git merge BranchA (it will merge BranchB with BranchA. Here you have merged code in branch B)

If you want to push your branch code to remote repo then do

• git push origin master (it will push your BranchB code to remote repo)

Whether something is a "checked exception" has nothing to do with whether you catch it or what you do in the catch block. It's a property of exception classes. Anything that is a subclass of Exception except for RuntimeException and its subclasses is a checked exception.

The Java compiler forces you to either catch checked exceptions or declare them in the method signature. It was supposed to improve program safety, but the majority opinion seems to be that it's not worth the design problems it creates.

Why do they let the exception bubble up? Isnt handle error the sooner the better? Why bubble up?

Because that's the entire point of exceptions. Without this possibility, you would not need exceptions. They enable you to handle errors at a level you choose, rather than forcing you to deal with them in low-level methods where they originally occur.

Now most browsers support getBoundingClientRect method, which has become the best practice. Using an old answer is very slow, not accurate and has several bugs.

The solution selected as correct is almost never precise. You can read more about its bugs.

This solution was tested on Internet Explorer 7 (and later), iOS 5 (and later) Safari, Android 2.0 (Eclair) and later, BlackBerry, Opera Mobile, and Internet Explorer Mobile ⁹.

function isElementInViewport (el) {

    // Special bonus for those using jQuery
    if (typeof jQuery === "function" && el instanceof jQuery) {
        el = el[0];
    }

    var rect = el.getBoundingClientRect();

    return (
        rect.top >= 0 &&
        rect.left >= 0 &&
        rect.bottom <= (window.innerHeight || document.documentElement.clientHeight) && /* or $(window).height() */
        rect.right <= (window.innerWidth || document.documentElement.clientWidth) /* or $(window).width() */
    );
}

How to use:

You can be sure that the function given above returns correct answer at the moment of time when it is called, but what about tracking element's visibility as an event?

Place the following code at the bottom of your <body> tag:

function onVisibilityChange(el, callback) {
    var old_visible;
    return function () {
        var visible = isElementInViewport(el);
        if (visible != old_visible) {
            old_visible = visible;
            if (typeof callback == 'function') {
                callback();

If you do any DOM modifications, they can change your element's visibility of course.

Guidelines and common pitfalls:

Maybe you need to track page zoom / mobile device pinch? jQuery should handle zoom/pinch cross browser, otherwise first or second link should help you.

If you modify DOM, it can affect the element's visibility. You should take control over that and call handler() manually. Unfortunately, we don't have any cross browser onrepaint event. On the other hand that allows us to make optimizations and perform re-check only on DOM modifications that can change an element's visibility.

Never Ever use it inside jQuery $(document).ready() only, because there is no warranty CSS has been applied in this moment. Your code can work locally with your CSS on a hard drive, but once put on a remote server it will fail.

After DOMContentLoaded is fired, styles are applied, but the images are not loaded yet. So, we should add window.onload event listener.

We can't catch zoom/pinch event yet.

The last resort could be the following code:

/* TODO: this looks like a very bad code */
setInterval(handler, 600);

You can use the awesome feature pageVisibiliy of the HTML5 API if you care if the tab with your web page is active and visible.

TODO: this method does not handle two situations:

• overlapping using z-index
• using overflow-scroll in element's container
• try something new - The Intersection Observer API explained

Old question, but I sure wish I read this answer here before I started my own search for a good solution. Calligraphy extends the android:fontFamily attribute to add support for custom fonts in your asset folder, like so:

<TextView 
  android:text="@string/hello_world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:fontFamily="fonts/Roboto-Bold.ttf"/>

The only thing you have to do to activate it is attaching it to the Context of the Activity you're using:

@Override
protected void attachBaseContext(Context newBase) {
    super.attachBaseContext(new CalligraphyContextWrapper(newBase));
}

You can also specify your own custom attribute to replace android:fontFamily

It also works in themes, including the AppTheme.

To run wget command in PHP you have to do following steps :

1) Allow apache server to use wget command by adding it in sudoers list.

2) Check "exec" function enabled or exist in your PHP config.

3) Run "exec" command as root user i.e. sudo user

Below code sample as per ubuntu machine

#Add apache in sudoers list to use wget command
~$ sudo nano /etc/sudoers
#add below line in the sudoers file
www-data ALL=(ALL) NOPASSWD: /usr/bin/wget


##Now in PHP file run wget command as 
exec("/usr/bin/sudo wget -P PATH_WHERE_WANT_TO_PLACE_FILE URL_OF_FILE");

I made a little test (Perl v5.20.1 under FreeBSD in VM) calling the following blocks 1.000.000 times each:

A

my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) = localtime(time);
my $now = sprintf("%04d-%02d-%02d %02d:%02d:%02d", $year+1900, $mon+1, $mday, $hour, $min, $sec);

B

my $now = strftime('%Y%m%d%H%M%S',localtime);

C

my $now = Time::Piece::localtime->strftime('%Y%m%d%H%M%S');

with the following results:

A: 2 seconds

B: 11 seconds

C: 19 seconds

This is of course not a thorough test or benchmark, but at least it is reproducable for me, so even though it is more complicated, I'd prefer the first method if generating a datetimestamp is required very often.

Calling (eg. under FreeBSD 10.1)

my $now = `date "+%Y%m%d%H%M%S" | tr -d "\n"`;

might not be such a good idea because it is not OS-independent and takes quite some time.

This works:

Protected Sub grid_RowDataBound(sender As Object, e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles grid.RowDataBound
    If e.Row.RowType = DataControlRowType.DataRow Then
        If e.Row.Cells(3).Text = "True" Then
            e.Row.Cells(3).Text = "Si"
        Else
            e.Row.Cells(3).Text = "No"
        End If
    End If
End Sub

Where cells(3) is the column of the column that has the boolean field.

There are a few ways to do this.

Using char struct (to string and back again)

string _stringOfA = char.ConvertFromUtf32(65);

int _asciiOfA = char.ConvertToUtf32("A", 0);

Simply casting the value (char and string shown)

char _charA = (char)65;

string _stringA = ((char)65).ToString();

Using ASCIIEncoding.
This can be used in a loop to do a whole array of bytes

var _bytearray = new byte[] { 65 };

ASCIIEncoding _asiiencode = new ASCIIEncoding();

string _alpha = _asiiencode .GetString(_newByte, 0, 1);

You can override the type converter class, this would allow you to do some fancy validation of the values:

var _converter = new ASCIIConverter();

string _stringA = (string)_converter.ConvertFrom(65);

int _intOfA = (int)_converter.ConvertTo("A", typeof(int));

Here is the Class:

public class ASCIIConverter : TypeConverter
{
    // Overrides the CanConvertFrom method of TypeConverter.
    // The ITypeDescriptorContext interface provides the context for the
    // conversion. Typically, this interface is used at design time to 
    // provide information about the design-time container.
    public override bool CanConvertFrom(ITypeDescriptorContext context,
       Type sourceType)
    {
        if (sourceType == typeof(string))
        {
            return true;
        }
        return base.CanConvertFrom(context, sourceType);
    }

    public override bool CanConvertTo(ITypeDescriptorContext context, Type destinationType)
    {
        if (destinationType == typeof(int))
        {
            return true;
        }
        return base.CanConvertTo(context, destinationType);
    }


    // Overrides the ConvertFrom method of TypeConverter.
    public override object ConvertFrom(ITypeDescriptorContext context,
       CultureInfo culture, object value)
    {

        if (value is int)
        {
            //you can validate a range of int values here
            //for instance 
            //if (value >= 48 && value <= 57)
            //throw error
            //end if

            return char.ConvertFromUtf32(65);
        }
        return base.ConvertFrom(context, culture, value);
    }

    // Overrides the ConvertTo method of TypeConverter.
    public override object ConvertTo(ITypeDescriptorContext context,
       CultureInfo culture, object value, Type destinationType)
    {
        if (destinationType == typeof(int))
        {
            return char.ConvertToUtf32((string)value, 0);
        }
        return base.ConvertTo(context, culture, value, destinationType);
    }
}

A little late but someone can use this in future...You can increase your test timeout by updating scripts in your package.json with the following:

"scripts": { "test": "test --timeout 10000" //Adjust to a value you need }

Run your tests using the command test

After looking in-depth, it's straight forward.

AsyncTask:

It's a simple way to use a thread without knowing anything about the java thread model. AsyncTask gives various callbacks respective to the worker thread and main thread.

Use for small waiting operations like the following:

1. Fetching some data from web services and display over the layout.
2. Database query.
3. When you realize that running operation will never, ever be nested.

Handler:

When we install an application in android, then it creates a thread for that application called MAIN UI Thread. All activities run inside that thread. By the android single thread model rule, we can not access UI elements (bitmap, textview, etc..) directly for another thread defined inside that activity.

A Handler allows you to communicate back with the UI thread from other background threads. This is useful in android as android doesn’t allow other threads to communicate directly with UI thread. A handler can send and process Message and Runnable objects associated with a thread’s MessageQueue. Each Handler instance is associated with a single thread and that thread’s message queue. When a new Handler is created, it is bound to the thread/message queue of the thread that is creating it.

It's the best fit for:

1. It allows you to do message queuing.
2. Message scheduling.

Thread:

Now it's time to talk about the thread.

Thread is the parent of both AsyncTask and Handler. They both internally use thread, which means you can also create your own thread model like AsyncTask and Handler, but that requires a good knowledge of Java's Multi-Threading Implementation.

Apologies for my previously mixed up answer.

Here is how to do:

myTreeView.SelectedNode = myTreeNode;

(Update)

I have tested the code below and it works:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        treeView1.Nodes.Add("1", "1");
        treeView1.Nodes.Add("2", "2");
        treeView1.Nodes[0].Nodes.Add("1-1", "1-1");
        TreeNode treeNode = treeView1.Nodes[0].Nodes.Add("1-2", "1-3");
        treeView1.SelectedNode = treeNode;
        MessageBox.Show(treeNode.IsSelected.ToString());
    }


}

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

As of Express 4.x

app.js

// above is all your node requires

// view engine setup
app.set('views', path.join(__dirname, 'views')); <-- ./views has all your .ejs files
app.set('view engine', 'ejs');

error.ejs

<!-- because ejs knows your root directory for views, you can navigate to the ./base directory and select the header.ejs file and include it -->

<% include ./base/header %> 
<h1> Other mark up here </h1>
<% include ./base/footer %>

On Centos, RedHat, Fedora and other yum-my systems it is much simpler than the PHP manual suggests:

yum install php-mbstring
service httpd restart

If you aren't allowing the column to be Null you need to provide a default to populate existing rows. e.g.

ALTER TABLE dbo.YourTbl ADD
    newcol int NOT NULL CONSTRAINT DF_YourTbl_newcol DEFAULT 0

On Enterprise Edition this is a metadata only change since 2012

@laryx-decidua: I think you are only seeing the 18.x instant client releases that are in the ol7_oci_included repo. The 19.x instant client RPMs, at the moment, are only in the ol7_oracle_instantclient repo. Easiest way to access that repo is:

yum install oracle-release-el7

This is a Matlab implementation using the polar form of the Box-Muller transformation:

Function randn_box_muller.m:

function [values] = randn_box_muller(n, mean, std_dev)
    if nargin == 1
       mean = 0;
       std_dev = 1;
    end

    r = gaussRandomN(n);
    values = r.*std_dev - mean;
end

function [values] = gaussRandomN(n)
    [u, v, r] = gaussRandomNValid(n);

    c = sqrt(-2*log(r)./r);
    values = u.*c;
end

function [u, v, r] = gaussRandomNValid(n)
    r = zeros(n, 1);
    u = zeros(n, 1);
    v = zeros(n, 1);

    filter = r==0 | r>=1;

    % if outside interval [0,1] start over
    while n ~= 0
        u(filter) = 2*rand(n, 1)-1;
        v(filter) = 2*rand(n, 1)-1;
        r(filter) = u(filter).*u(filter) + v(filter).*v(filter);

        filter = r==0 | r>=1;
        n = size(r(filter),1);
    end
end

And invoking histfit(randn_box_muller(10000000),100); this is the result:

Obviously it is really inefficient compared with the Matlab built-in randn.

You can simulate pointers to instantiated objects to some degree:

class pointer {
   var $child;

   function pointer(&$child) {
       $this->child = $child;
   }

   public function __call($name, $arguments) {
       return call_user_func_array(
           array($this->child, $name), $arguments);
   }
}

Use like this:

$a = new ClassA();

$p = new pointer($a);

If you pass $p around, it will behave like a C++ pointer regarding method calls (you can't touch object variables directly, but that's evil anyways :) ).

unset is not actually a function, but a language construct. It is no more a function call than a return or an include.

Aside from performance issues, using unset makes your code's intent much clearer.

Have you tried using gzip.open?

with gzip.open('my.csv', 'rb') as data_file:

I was trying to open a file that had been compressed but had the extension '.csv' instead of 'csv.gz'. This error kept showing up until I used gzip.open

If the name's dynamic, then you must have something like

$arr[$key]

which'd mean that $key contains the value of the key.

You can use array_keys() to get ALL the keys of an array, e.g.

$arr = array('a' => 'b', 'c' => 'd')
$x = array_keys($arr);

would give you

$x = array(0 => 'a', 1 => 'c');

If you put the username and password at clientside into the request this way:

URL url = new URL("http://localhost:8080/myapplication?wsdl");
MyWebService webservice = new MyWebServiceImplService(url).getMyWebServiceImplPort();
Map<String, Object> requestContext = ((BindingProvider) webservice).getRequestContext();
requestContext.put(BindingProvider.USERNAME_PROPERTY, "myusername");
requestContext.put(BindingProvider.PASSWORD_PROPERTY, "mypassword");

and call your webservice

String response = webservice.someMethodAtMyWebservice("test");

Then you can read the Basic Authentication string like this at the server side (you have to add some checks and do some exceptionhandling):

@Resource
WebServiceContext webserviceContext;

public void someMethodAtMyWebservice(String parameter) {
    MessageContext messageContext = webserviceContext.getMessageContext();
    Map<String, ?> httpRequestHeaders = (Map<String, ?>) messageContext.get(MessageContext.HTTP_REQUEST_HEADERS);
    List<?> authorizationList = (List<?>) httpRequestHeaders.get("Authorization");
    if (authorizationList != null && !authorizationList.isEmpty()) {
        String basicString = (String) authorizationList.get(0);
        String encodedBasicString = basicString.substring("Basic ".length());
        String decoded = new String(Base64.getDecoder().decode(encodedBasicString), StandardCharsets.UTF_8);
        String[] splitter = decoded.split(":");
        String usernameFromBasicAuth = splitter[0];
        String passwordFromBasicAuth = splitter[1];
    }

Thanks to gene tsai, here is some modifications to his code to run on my target page:

csv = []
rows = $('#data tr');
for(i =0;i < rows.length;i++) {
    cells = $(rows[i]).find('td,th');
    csv_row = [];
    for (j=0;j<cells.length;j++) {
        txt = cells[j].innerText;
        csv_row.push(txt.replace(",", "-"));
    }
    csv.push(csv_row.join(","));
}
output = csv.join("\n")

improvements:

• Use generic JavaScript for loop
• make sure each cell does not have a comma

Assuming you mean "list" where you say "array", you can do

if item in my_list:
    # whatever

This works for any collection, not just for lists. For dictionaries, it checks whether the given key is present in the dictionary.

In addition to previous answers there is one important for me note:

shelve is JetBrains products feature (such as WebStorm, PhpStorm, PyCharm, etc.). It puts shelved files into .idea/shelf directory.

stash is one of git options. It puts stashed files under the .git directory.
