Had similar issue. Had to pin the maven deploy plugin to specific version in pom.xml:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-deploy-plugin</artifactId>
     <version>2.8.2</version>
</plugin>

This version is what broke my builds:

[INFO] --- maven-deploy-plugin:3.0.0-M1:deploy (default-cli) @ dbl ---

I'm posting this answer with the hope of someone sharing with me if and why it would be a bad idea. In my application, I have a property of Type that I want to check to be sure it is typeof(A) or typeof(B), where B is any class derived from A. So my code:

public class A
{
}

public class B : A
{
}

public class MyClass
{
    private Type _helperType;
    public Type HelperType
    {
        get { return _helperType; }
        set 
        {
            var testInstance = (A)Activator.CreateInstance(value);
            if (testInstance==null)
                throw new InvalidCastException("HelperType must be derived from A");
            _helperType = value;
        }
    }
}

I feel like I might be a bit naive here so any feedback would be welcome.

There is an application for both Mac & Windows call Handbrake, i know this isn't command line stuff but for a quick open file - select output file format & rough output size whilst keeping most of the good stuff about the video then this is good, it's a just a graphical view of ffmpeg at its best ... It does support command line input for those die hard texters.. https://handbrake.fr/downloads.php

OFFSET is what you are looking for.

SELECT * FROM table LIMIT 10 OFFSET 10

The meaning of the completely undocumented error 800A03EC (shame on Microsoft!) is something like "OPERATION NOT SUPPORTED".

It may happen

• when you open a document that has a content created by a newer Excel version, which your current Excel version does not understand.
• when you save a document to the same path where you have loaded it from (file is already open and locked)

But mostly you will see this error due to severe bugs in Excel.

• For example Microsoft.Office.Interop.Excel.Picture has a property "Enabled". When you call it you should receive a bool value. But instead you get an error 800A03EC. This is a bug.
• And there is a very fat bug in Exel 2013 and 2016: When you automate an Excel process and set Application.Visible=true and Application.WindowState = XlWindowState.xlMinimized then you will get hundreds of 800A03EC errors from different functions (like Range.Merge(), CheckBox.Text, Shape.TopLeftCell, Shape.Locked and many more). This bug does not exist in Excel 2007 and 2010.

The problem lies that you haven't added Model to either the bootstrap (which will make it a singleton), or to the providers array of your component definition:

@Component({
    selector: "testWidget",
    template: "<div>This is a test and {{param1}} is my param.</div>",
    providers : [
       Model
    ]
})

export class testWidget {
    constructor(private model: Model) {}
}

And yes, you should define Model above the Component. But better would be to put it in his own file.

But if you want it to be just a class from which you can create multiple instances, you better just use new.

@Component({
    selector: "testWidget",
    template: "<div>This is a test and {{param1}} is my param.</div>"
})

export class testWidget {

    private model: Model = new Model();

    constructor() {}
}

You could also use a URI template. If you structured your request into a restful URL Spring could parse the provided value from the url.

HTML

<li>
    <a id="byParameter" 
       class="textLink" href="<c:url value="/mapping/parameter/bar />">By path, method,and
           presence of parameter</a>
</li>

Controller

@RequestMapping(value="/mapping/parameter/{foo}", method=RequestMethod.GET)
public @ResponseBody String byParameter(@PathVariable String foo) {
    //Perform logic with foo
    return "Mapped by path + method + presence of query parameter! (MappingController)";
}

Spring URI Template Documentation

In my case delete your gradle file and then again import your file again it will work

Insert a new verse after the given verse in your stanza:

sed -i '/^lorem ipsum dolor sit amet$/ s:$:\nconsectetur adipiscing elit:' FILE

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

Another thing: When you have more than one spinner in your layout, you have to implement a switch selection in the onItemSlected() method to know which widget was clicked. Something like this:

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    switch (parent.getId()){
        case R.id.sp_alarmSelection:
            //Do something
            Toast.makeText(this, "Alarm Selected: " + parent.getSelectedItem().toString(), Toast.LENGTH_SHORT).show();
            break;
        case R.id.sp_optionSelection:
            //Do another thing 
            Toast.makeText(this, "Option Selected: " + parent.getSelectedItem().toString(), Toast.LENGTH_SHORT).show();
            break;
    }
}

Just like you said

select * from tbl where statusid is null

or

select * from tbl where statusid is not null

If your statusid is not null, then it will be selected just fine when you have an actual value, no need for any "if" logic if that is what you were thinking

select * from tbl where statusid = 123 -- the record(s) returned will not have null statusid

if you want to select where it is null or a value, try

select * from tbl where statusid = 123 or statusid is null

public ActionResult Download()
{
    var document = ...
    var cd = new System.Net.Mime.ContentDisposition
    {
        // for example foo.bak
        FileName = document.FileName, 

        // always prompt the user for downloading, set to true if you want 
        // the browser to try to show the file inline
        Inline = false, 
    };
    Response.AppendHeader("Content-Disposition", cd.ToString());
    return File(document.Data, document.ContentType);
}

NOTE: This example code above fails to properly account for international characters in the filename. See RFC6266 for the relevant standardization. I believe recent versions of ASP.Net MVC's File() method and the ContentDispositionHeaderValue class properly accounts for this. - Oskar 2016-02-25

You don't import scripts in Python you import modules. Some python modules are also scripts that you can run directly (they do some useful work at a module-level).

In general it is preferable to use absolute imports rather than relative imports.

toplevel_package/
+-- __init__.py
+-- moduleA.py
+-- subpackage
    +-- __init__.py
    +-- moduleB.py

In moduleB:

from toplevel_package import moduleA

If you'd like to run moduleB.py as a script then make sure that parent directory for toplevel_package is in your sys.path.

If you want the threads to stop when your program exits (as implied by your example), then make them daemon threads.

If you want your threads to die on command, then you have to do it by hand. There are various methods, but all involve doing a check in your thread's loop to see if it's time to exit (see Nix's example).

If your class extends Serializable, you can write and read objects through a ByteArrayOutputStream, that's what I usually do.

In short: Replace badge-important with either alert-danger or progress-bar-danger.

It looks like this: Bootply Demo.

You might combine the CSS class badge with alert-* or progess-bar-* to color them:

With class="badges alert-*"

  <span class="badge alert-info">badge</span> Info
  <span class="badge alert-success">badge</span> Success 
  <span class="badge alert-danger">badge</span> Danger   
  <span class="badge alert-warning">badge</span> Warning

Alerts Docu: http://getbootstrap.com/components/#alerts

With class="badges progress-bar-*" (as suggested by @clami219)

  <span class="badge progress-bar-info">badge</span> Info
  <span class="badge progress-bar-success">badge</span> Success
  <span class="badge progress-bar-danger">badge</span> Danger
  <span class="badge progress-bar-warning">badge</span> Warning

Progress-Bar Docu: http://getbootstrap.com/components/#progress-alternatives

Note that in general, IDE's like Visual Studio will markup a comment in the context of the current language, by selecting the text you wish to turn into a comment, and then using the Ctrl+K Ctrl+C shortcut, or if you are using Resharper / Intelli-J style shortcuts, then Ctrl+/.

Server side Comments:

Razor .cshtml

Like so:

@* Comment goes here *@

.aspx
For those looking for the older .aspx view (and Asp.Net WebForms) server side comment syntax:

<%-- Comment goes here --%>

Client Side Comments

HTML Comment

<!-- Comment goes here -->

Javascript Comment

// One line Comment goes Here
/* Multiline comment
   goes here */

As OP mentions, although not displayed on the browser, client side comments will still be generated for the page / script file on the server and downloaded by the page over HTTP, which unless removed (e.g. minification), will waste I/O, and, since the comment can be viewed by the user by viewing the page source or intercepting the traffic with the browser's Dev Tools or a tool like Fiddler or Wireshark, can also pose a security risk, hence the preference to use server side comments on server generated code (like MVC views or .aspx pages).

Since your coordinates belong together as pairs, why not write a struct for them?

struct CoordinatePair
{
    int x;
    int y;
};

Then you can write an overloaded extraction operator for istreams:

std::istream& operator>>(std::istream& is, CoordinatePair& coordinates)
{
    is >> coordinates.x >> coordinates.y;

    return is;
}

And then you can read a file of coordinates straight into a vector like this:

#include <fstream>
#include <iterator>
#include <vector>

int main()
{
    char filename[] = "coordinates.txt";
    std::vector<CoordinatePair> v;
    std::ifstream ifs(filename);
    if (ifs) {
        std::copy(std::istream_iterator<CoordinatePair>(ifs), 
                std::istream_iterator<CoordinatePair>(),
                std::back_inserter(v));
    }
    else {
        std::cerr << "Couldn't open " << filename << " for reading\n";
    }
    // Now you can work with the contents of v
}

Well I had situation when web service returned a color in hex format like "#CC2233" and I wanted to put this color on textView by using setBackGroundColor(), so I used android Color class to get int value of hex string and passed it to mentioned function. Everything worked. This is example:

String myHexColor = "#CC2233";
TextView myView = (TextView) findViewById(R.id.myTextView);
myView.setBackGroundColor(Color.pasrsehexString(myHexColor));

P.S. posted this answer because other solutions didn't work for me. I hope this will help someone:)

Either of the following SQL will return all schema in Oracle DB.

1. select owner FROM all_tables group by owner;
2. select distinct owner FROM all_tables;

I use the free file searching program Everything, search for *.sql files across my C: drive, and then sort by Last Modified, and then browse by the date I think it was probably last executed.

It usually brings up loads of autorecovery files from a variety of locations. And you don't have to worry where the latest version of SSMS/VS is saving the backup files this version.

If you want to get source map file different version, you can use this link http://code.jquery.com/jquery-x.xx.x.min.map

Instead x.xx.x put your version number.

Note: Some links, which you get on this method, may be broken :)

Expanding on Felix Turner s response, here is how I would use this approach with the fetch API.

async function createFile(){
  let response = await fetch('http://127.0.0.1:8080/test.jpg');
  let data = await response.blob();
  let metadata = {
    type: 'image/jpeg'
  };
  let file = new File([data], "test.jpg", metadata);
  // ... do something with the file or return it
}
createFile();

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed). Use one of those.

Here is another way of doing it.

public string formatPhoneNumber(string _phoneNum)
{
    string phoneNum = _phoneNum;
    if (phoneNum == null)
        phoneNum = "";
    phoneNum = phoneNum.PadRight(10 - phoneNum.Length);
    phoneNum = phoneNum.Insert(0, "(").Insert(4,") ").Insert(9,"-");
    return phoneNum;
}

Use set -u which will cause any unset argument reference to immediately fail the script.

Please, see the article: Writing Robust Bash Shell Scripts - David Pashley.com.

Use it like this, should work:

 <a routerLink="/Service/Sign_in"><button class="btn btn-success pull-right" > Add Customer</button></a>

You can also use router.navigateByUrl('..') like this:

<button type="button" class="btn btn-primary-outline pull-right" (click)="btnClick();"><i class="fa fa-plus"></i> Add</button>    

import { Router } from '@angular/router';

btnClick= function () {
        this.router.navigateByUrl('/user');
};

Update 1

You have to inject Router in the constructor like this:

constructor(private router: Router) { }

only then you are able to use this.router. Remember also to import RouterModule in your module.

Update 2

Now, After Angular v4 you can directly add routerLink attribute on the button (As mentioned by @mark in comment section) like below (No "'/url?" since Angular 6, when a Route in RouterModule exists) -

 <button [routerLink]="'url'"> Button Label</button>

Don't think anyone has mentioned it yet, but if you are sure the data won't change underneath you, you may want to also apply the NoLock hint to ensure it is not blocked when reading.

SELECT CASE WHEN EXISTS (SELECT 1 
                     FROM dbo.[YourTable] WITH (NOLOCK)
                     WHERE [YourColumn] = [YourValue]) 
        THEN CAST (1 AS BIT) 
        ELSE CAST (0 AS BIT) END

for me replace doesn't work... try this code:

str = str.split(""").join('"');

#!/bin/bash

if [[ $(which ${JAVA_HOME}/bin/java) ]]; then
    exe="${JAVA_HOME}/bin/java"
elif [[ $(which java) ]]; then
    exe="java"
else 
    echo "Java environment is not detected."
    exit 1
fi

${exe} -version

For windows:

@echo off
if "%JAVA_HOME%" == "" goto nojavahome

echo Using JAVA_HOME            :   %JAVA_HOME%

"%JAVA_HOME%/bin/java.exe" -version
goto exit

:nojavahome
echo The JAVA_HOME environment variable is not defined correctly
echo This environment variable is needed to run this program.
goto exit

:exit

Ensure you have an index on your firstname and lastname columns and go with 1. This really won't have much of a performance impact at all.

EDIT: After @Dems comment regarding spamming the plan cache ,a better solution might be to create a computed column on the existing table (or a separate view) which contained a concatenated Firstname + Lastname value, thus allowing you to execute a query such as

SELECT City 
FROM User 
WHERE Fullname in (@fullnames)

where @fullnames looks a bit like "'JonDoe', 'JaneDoe'" etc

As its name is "numbers" it is clear it is a list of number... So an array of number... no need of the attribute type... Although I like the principle of specifying the type of field in a type attribute...

Thread.sleep() is simple for the beginners and may be appropriate for unit tests and proofs of concept.

But please DO NOT use sleep() for production code. Eventually sleep() may bite you badly.

Best practice for multithreaded/multicore java applications to use the "thread wait" concept. Wait releases all the locks and monitors held by the thread, which allows other threads to acquire those monitors and proceed while your thread is sleeping peacefully.

Code below demonstrates that technique:

import java.util.concurrent.TimeUnit;
public class DelaySample {
    public static void main(String[] args) {
       DelayUtil d = new DelayUtil();
       System.out.println("started:"+ new Date());
       d.delay(500);
       System.out.println("half second after:"+ new Date());
       d.delay(1, TimeUnit.MINUTES); 
       System.out.println("1 minute after:"+ new Date());
    }
}

DelayUtil implementation:

import java.util.concurrent.TimeUnit;
import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.ReentrantLock;

public class DelayUtil {
    /** 
    *  Delays the current thread execution. 
    *  The thread loses ownership of any monitors. 
    *  Quits immediately if the thread is interrupted
    *  
    * @param durationInMillis the time duration in milliseconds
    */
   public void delay(final long durationInMillis) {
      delay(durationInMillis, TimeUnit.MILLISECONDS);
   }

   /** 
    * @param duration the time duration in the given {@code sourceUnit}
    * @param unit
    */
    public void delay(final long duration, final TimeUnit unit) {
        long currentTime = System.currentTimeMillis();
        long deadline = currentTime+unit.toMillis(duration);
        ReentrantLock lock = new ReentrantLock();
        Condition waitCondition = lock.newCondition();

        while ((deadline-currentTime)>0) {
            try {
                lock.lockInterruptibly();    
                waitCondition.await(deadline-currentTime, TimeUnit.MILLISECONDS);
            } catch (InterruptedException e) {
                Thread.currentThread().interrupt();
                return;
            } finally {
                lock.unlock();
            }
            currentTime = System.currentTimeMillis();
        }
    }
}

Very very very simpely no other modules !!!

import os
p = r"C:\Users\bilal\Documents\face Recognition python\imgs\northon.jpg"

# Get the filename only from the initial file path.
filename = os.path.basename(p)

# Use splitext() to get filename and extension separately.
(file, ext) = os.path.splitext(filename)

# Print outcome.
print("Filename without extension =", file)
print("Extension =", ext)

In PostgreSQL 9.0+ you would do the following:

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA MY_SCHEMA TO MY_GROUP;
GRANT ALL PRIVILEGES ON ALL SEQUENCES IN SCHEMA MY_SCHEMA TO MY_GROUP;

If you want to enable this for newly created relations too, then set the default permissions:

ALTER DEFAULT PRIVILEGES IN SCHEMA MY_SCHEMA
  GRANT ALL PRIVILEGES ON TABLES TO MY_GROUP;
ALTER DEFAULT PRIVILEGES IN SCHEMA MY_SCHEMA
  GRANT ALL PRIVILEGES ON SEQUENCES TO MY_GROUP;

However, seeing that you use 8.1 you have to code it yourself:

CREATE FUNCTION grant_all_in_schema (schname name, grant_to name) RETURNS integer AS $$
DECLARE
  rel RECORD;
BEGIN
  FOR rel IN
    SELECT c.relname
    FROM pg_class c
    JOIN pg_namespace s ON c.namespace = s.oid
    WHERE s.nspname = schname
  LOOP
    EXECUTE 'GRANT ALL PRIVILEGES ON ' || quote_ident(schname) || '.' || rel.relname || ' TO ' || quote_ident(grant_to);
  END LOOP;
  RETURN 1;
END; $$ LANGUAGE plpgsql STRICT;
REVOKE ALL ON FUNCTION grant_all_in_schema(name, name) FROM PUBLIC;

This will set the privileges on all relations: tables, views, indexes, sequences, etc. If you want to restrict that, filter on pg_class.relkind. See the pg_class docs for details.

You should run this function as superuser and as regular as your application requires. An option would be to package this in a cron job that executes every day or every hour.

Use below code to change background color of edit-text's border.

Create new XML file under drawable.

abc.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="#00000000" />
    <stroke android:width="1dip" android:color="#ffffff" />
</shape>

and add it as background of your edit-text

android:background="@drawable/abc"

This is a part from a REST-Service I´ve written recently.

var select = $("#productSelect")
for (var prop in data) {
    var option = document.createElement('option');
    option.innerHTML = data[prop].ProduktName
    option.value = data[prop].ProduktName;
    select.append(option)
}

The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.

You can do it in one sql statement for existing customers, 3 statements for new ones. All you have to do is be an optimist and act as though the customer already exists:

insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);

If the customer does not exist, you'll get an sql exception which text will be something like:

null value in column "customer_id" violates not-null constraint

(providing you made customer_id non-nullable, which I'm sure you did). When that exception occurs, insert the customer into the customer table and redo the insert into the order table:

insert into customer(name) values ('John');
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);

Unless your business is growing at a rate that will make "where to put all the money" your only real problem, most of your inserts will be for existing customers. So, most of the time, the exception won't occur and you'll be done in one statement.

There is a very simple to use library with gradle support: https://github.com/cachapa/ExpandableLayout.

Right from the library docs:

<net.cachapa.expandablelayout.ExpandableLinearLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:el_duration="1000"
    app:el_expanded="true">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Click here to toggle expansion" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:text="Fixed height"
        app:layout_expandable="true" />

 </net.cachapa.expandablelayout.ExpandableLinearLayout>

After you mark your expandable views, just call any of these methods on the container: expand(), collapse() or toggle()

i had the same problem, i added the following lines in build.gradle

allprojects {
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }

        maven {
            url 'http://dl.bintray.com/dev-fingerlinks/maven'
        }
        mavenCentral()
    }
}

This is a workaround, but works for me:

Created res/drawable/divider.xml as follows:

<?xml version="1.0" encoding="UTF-8"?>
<shape
  xmlns:android="http://schemas.android.com/apk/res/android">
    <gradient android:startColor="#ffcdcdcd" android:endColor="#ffcdcdcd" android:angle="270.0" />
</shape>

And in styles.xml for listview item, I added the following lines:

    <item name="android:divider">@drawable/divider</item>
    <item name="android:dividerHeight">1px</item>

Crucial part was to include this 1px setting. Of course, drawable uses gradient (with 1px) and that's not the optimal solution. I tried using stroke but didn't get it to work. (You don't seem to use styles, so just add android:dividerHeight="1px" attribute for the ListView.

I made this procedure for us to use at work.

cd ~
curl -s https://pypi.python.org/packages/source/p/pip/pip-1.3.1.tar.gz | tar xvz
cd pip-1.3.1
python setup.py install --user
cd ~
rm -rf pip-1.3.1

$HOME/.local/bin/pip install --user --upgrade pip distribute virtualenvwrapper

# Might want these three in your .bashrc
export PATH=$PATH:$HOME/.local/bin
export VIRTUALENVWRAPPER_VIRTUALENV_ARGS="--distribute"
source $HOME/.local/bin/virtualenvwrapper.sh

mkvirtualenv mypy
workon mypy
pip install --upgrade distribute
pip install pudb # Or whatever other nice package you might want.

Key points for the security minded:

1. curl does ssl validation. wget doesn't.
2. Starting from pip 1.3.1, pip also does ssl validation.
3. Fewer users can upload the pypi tarball than a github tarball.

Here are some options for using AJAX to upload files:

• AjaxFileUpload - Requires a form element on the page, but uploads the file without reloading the page. See the Demo.

• List of JQuery Plug-ins Tagged With "File"

• Uploadify - A Flash-based method of uploading files.

• How can I upload files asynchronously?

• Ten Examples of AJAX File Upload - This was posted this year.

UPDATE: Here is a JQuery plug-in for Multiple File Uploading.

Alternatively you can do like this :

     var _items = from a in StudentsGrades
                  group a by a.Name;

     foreach (var _itemGroup in _items)
     {
        foreach (var _item in _itemGroup.OrderBy(a=>a.grade))
        {
           ------------------------
           --------------------------
        }
     }

You can also try this code without floats (faster but less accurate):

typedef struct RgbColor
{
    unsigned char r;
    unsigned char g;
    unsigned char b;
} RgbColor;

typedef struct HsvColor
{
    unsigned char h;
    unsigned char s;
    unsigned char v;
} HsvColor;

RgbColor HsvToRgb(HsvColor hsv)
{
    RgbColor rgb;
    unsigned char region, remainder, p, q, t;

    if (hsv.s == 0)
    {
        rgb.r = hsv.v;
        rgb.g = hsv.v;
        rgb.b = hsv.v;
        return rgb;

To check is variable is set you need to use isset function.

$lorem = 'potato';

if(isset($lorem)){
    echo 'isset true' . '<br />';
}else{
    echo 'isset false' . '<br />';
}

if(isset($ipsum)){
    echo 'isset true' . '<br />';
}else{
    echo 'isset false' . '<br />';
}

this code will print:

isset true
isset false

AWS Ubuntu 18.04:

I have been using iPhone Configuration Utility to read the UDIDs and install the Development app. Still works fine on iOS7

Xcode 7.0.1 and iOS 9.1 are incompatible. You will need to update your version of Xcode via the Mac app store.

If your iOS version is lower then the Xcode version on the other hand, you can change the deployment target for a lower version of iOS by going to the General Settings and under Deployment set your Deployment Target:

Note:

Xcode 7.1 does not include iOS 9.2 beta SDK. Upgraded to Xcode to 7.2 beta by downloading it from the Xcode website.

Presumably from this site:

Internal Fragmentation Internal fragmentation occurs when the memory allocator leaves extra space empty inside of a block of memory that has been allocated for a client. This usually happens because the processor’s design stipulates that memory must be cut into blocks of certain sizes -- for example, blocks may be required to be evenly be divided by four, eight or 16 bytes. When this occurs, a client that needs 57 bytes of memory, for example, may be allocated a block that contains 60 bytes, or even 64. The extra bytes that the client doesn’t need go to waste, and over time these tiny chunks of unused memory can build up and create large quantities of memory that can’t be put to use by the allocator. Because all of these useless bytes are inside larger memory blocks, the fragmentation is considered internal.

External Fragmentation External fragmentation happens when the memory allocator leaves sections of unused memory blocks between portions of allocated memory. For example, if several memory blocks are allocated in a continuous line but one of the middle blocks in the line is freed (perhaps because the process that was using that block of memory stopped running), the free block is fragmented. The block is still available for use by the allocator later if there’s a need for memory that fits in that block, but the block is now unusable for larger memory needs. It cannot be lumped back in with the total free memory available to the system, as total memory must be contiguous for it to be useable for larger tasks. In this way, entire sections of free memory can end up isolated from the whole that are often too small for significant use, which creates an overall reduction of free memory that over time can lead to a lack of available memory for key tasks.

What is the cause?

The error message is pretty clear: you're trying to access a file, and it's not accessible because another process (or even the same process) is doing something with it (and it didn't allow any sharing).

Debugging

It may be pretty easy to solve (or pretty hard to understand), depending on your specific scenario. Let's see some.

Your process is the only one to access that file
You're sure the other process is your own process. If you know you open that file in another part of your program, then first of all you have to check that you properly close the file handle after each use. Here is an example of code with this bug:

var stream = new FileStream(path, FileAccess.Read);
var reader = new StreamReader(stream);
// Read data from this file, when I'm done I don't need it any more
File.Delete(path); // IOException: file is in use

Fortunately FileStream implements IDisposable, so it's easy to wrap all your code inside a using statement:

using (var stream = File.Open("myfile.txt", FileMode.Open)) {
    // Use stream
}

// Here stream is not accessible and it has been closed (also if
// an exception is thrown and stack unrolled

This pattern will also ensure that the file won't be left open in case of exceptions (it may be the reason the file is in use: something went wrong, and no one closed it; see this post for an example).

If everything seems fine (you're sure you always close every file you open, even in case of exceptions) and you have multiple working threads, then you have two options: rework your code to serialize file access (not always doable and not always wanted) or apply a retry pattern. It's a pretty common pattern for I/O operations: you try to do something and in case of error you wait and try again (did you ask yourself why, for example, Windows Shell takes some time to inform you that a file is in use and cannot be deleted?). In C# it's pretty easy to implement (see also better examples about disk I/O, networking and database access).

private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;

for (int i=1; i <= NumberOfRetries; ++i) {
    try {
        // Do stuff with file
        break; // When done we can break loop
    }
    catch (IOException e) when (i <= NumberOfRetries) {
        // You may check error code to filter some exceptions, not every error
        // can be recovered.
        Thread.Sleep(DelayOnRetry);
    }
}

Please note a common error we see very often on StackOverflow:

var stream = File.Open(path, FileOpen.Read);
var content = File.ReadAllText(path);

In this case ReadAllText() will fail because the file is in use (File.Open() in the line before). To open the file beforehand is not only unnecessary but also wrong. The same applies to all File functions that don't return a handle to the file you're working with: File.ReadAllText(), File.WriteAllText(), File.ReadAllLines(), File.WriteAllLines() and others (like File.AppendAllXyz() functions) will all open and close the file by themselves.

Your process is not the only one to access that file
If your process is not the only one to access that file, then interaction can be harder. A retry pattern will help (if the file shouldn't be open by anyone else but it is, then you need a utility like Process Explorer to check who is doing what).

Ways to avoid

When applicable, always use using statements to open files. As said in previous paragraph, it'll actively help you to avoid many common errors (see this post for an example on how not to use it).

If possible, try to decide who owns access to a specific file and centralize access through a few well-known methods. If, for example, you have a data file where your program reads and writes, then you should box all I/O code inside a single class. It'll make debug easier (because you can always put a breakpoint there and see who is doing what) and also it'll be a synchronization point (if required) for multiple access.

Don't forget I/O operations can always fail, a common example is this:

if (File.Exists(path))
    File.Delete(path);

If someone deletes the file after File.Exists() but before File.Delete(), then it'll throw an IOException in a place where you may wrongly feel safe.

Whenever it's possible, apply a retry pattern, and if you're using FileSystemWatcher, consider postponing action (because you'll get notified, but an application may still be working exclusively with that file).

Advanced scenarios
It's not always so easy, so you may need to share access with someone else. If, for example, you're reading from the beginning and writing to the end, you have at least two options.

1) share the same FileStream with proper synchronization functions (because it is not thread-safe). See this and this posts for an example.

2) use FileShare enumeration to instruct OS to allow other processes (or other parts of your own process) to access same file concurrently.

using (var stream = File.Open(path, FileMode.Open, FileAccess.Write, FileShare.Read))
{
}

In this example I showed how to open a file for writing and share for reading; please note that when reading and writing overlaps, it results in undefined or invalid data. It's a situation that must be handled when reading. Also note that this doesn't make access to the stream thread-safe, so this object can't be shared with multiple threads unless access is synchronized somehow (see previous links). Other sharing options are available, and they open up more complex scenarios. Please refer to MSDN for more details.

In general N processes can read from same file all together but only one should write, in a controlled scenario you may even enable concurrent writings but this can't be generalized in few text paragraphs inside this answer.

Is it possible to unlock a file used by another process? It's not always safe and not so easy but yes, it's possible.

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

setInterval(function () {document.getElementById("myButtonId").click();}, 1000);

Check: key = undef !!!

You got also the warn message:

Each child in a list should have a unique "key" prop.

if your code is complete right, but if on

<ObjectRow key={someValue} />

someValue is undefined!!! Please check this first. You can save hours.

Unfortunately although the Array.join approach mentioned here is terse, it is about 10X slower than a string-concatenation-based implementation. It performs especially badly on large strings. See below for full performance details.

On Firefox, Chrome, Node.js MacOS, Node.js Ubuntu, and Safari, the fastest implementation I tested was:

function repeatChar(count, ch) {
    if (count == 0) {
        return "";
    }
    var count2 = count / 2;
    var result = ch;

    // double the input until it is long enough.
    while (result.length <= count2) {
        result += result;
    }
    // use substring to hit the precise length target without
    // using extra memory
    return result + result.substring(0, count - result.length);
};

This is verbose, so if you want a terse implementation you could go with the naive approach; it still performs betweeb 2X to 10X better than the Array.join approach, and is also faster than the doubling implementation for small inputs. Code:

// naive approach: simply add the letters one by one
function repeatChar(count, ch) {
    var txt = "";
    for (var i = 0; i < count; i++) {
        txt += ch;
    }
    return txt;
}

This should do it:

sed -e s/deletethis//g -i *
sed -e "s/deletethis//g" -i.backup *
sed -e "s/deletethis//g" -i .backup *

it will replace all occurrences of "deletethis" with "" (nothing) in all files (*), editing them in place.

In the second form the pattern can be edited a little safer, and it makes backups of any modified files, by suffixing them with ".backup".

The third form is the way some versions of sed like it. (e.g. Mac OS X)

man sed for more information.

You can try opening the wsdl in web browser and saving with .wsdl extension. And set the WSDL in SOAP UI project to this .wsdl file. This really works.

Also make sure that you have allowed codeigniter to log the type of messages you want in a config file.

i.e $config['log_threshold'] = [log_level ranges 0-4];

DateTime.Now is what you're searching for...

If you do not have too many folders then I suggest you use if statements to choose an upload folder depending on the user input details. E.g.

String user= request.getParameter("username");
if (user=="Alfred"){
//Path A;
}
if (user=="other"){
//Path B;
}

Methods 1 and 2 work in Python 2 or 3, and they work on ragged, rectangular 2D lists. That means the inner lists do not need to have the same lengths as each other (ragged) or as the outer lists (rectangular). The other methods, well, it's complicated.

the setup

import itertools
import six

list_list = [[1,2,3], [4,5,6, 6.1, 6.2, 6.3], [7,8,9]]

method 1 — map(), zip_longest()

>>> list(map(list, six.moves.zip_longest(*list_list, fillvalue='-')))
[[1, 4, 7], [2, 5, 8], [3, 6, 9], ['-', 6.1, '-'], ['-', 6.2, '-'], ['-', 6.3, '-']]

six.moves.zip_longest() becomes

• itertools.izip_longest() in Python 2
• itertools.zip_longest() in Python 3

The default fillvalue is None. Thanks to @jena's answer, where map() is changing the inner tuples to lists. Here it is turning iterators into lists. Thanks to @Oregano's and @badp's comments.

In Python 3, pass the result through list() to get the same 2D list as method 2.

method 2 — list comprehension, zip_longest()

>>> [list(row) for row in six.moves.zip_longest(*list_list, fillvalue='-')]
[[1, 4, 7], [2, 5, 8], [3, 6, 9], ['-', 6.1, '-'], ['-', 6.2, '-'], ['-', 6.3, '-']]

The @inspectorG4dget alternative.

method 3 — map() of map() — broken in Python 3.6

>>> map(list, map(None, *list_list))
[[1, 4, 7], [2, 5, 8], [3, 6, 9], [None, 6.1, None], [None, 6.2, None], [None, 6.3, None]]

This extraordinarily compact @SiggyF second alternative works with ragged 2D lists, unlike his first code which uses numpy to transpose and pass through ragged lists. But None has to be the fill value. (No, the None passed to the inner map() is not the fill value. It means there is no function to process each column. The columns are just passed through to the outer map() which converts them from tuples to lists.)

Somewhere in Python 3, map() stopped putting up with all this abuse: the first parameter cannot be None, and ragged iterators are just truncated to the shortest. The other methods still work because this only applies to the inner map().

method 4 — map() of map() revisited

>>> list(map(list, map(lambda *args: args, *list_list)))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]   // Python 2.7
[[1, 4, 7], [2, 5, 8], [3, 6, 9], [None, 6.1, None], [None, 6.2, None], [None, 6.3, None]] // 3.6+

Alas the ragged rows do NOT become ragged columns in Python 3, they are just truncated. Boo hoo progress.

Try this one too:

let base64="iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==";
let buffer=Uint8Array.from(atob(base64), c => c.charCodeAt(0));
let blob=new Blob([buffer], { type: "image/gif" });
let url=URL.createObjectURL(blob);
let img=document.createElement("img");
img.src=url;
document.body.appendChild(img);

Not recommended for production as it is only compatible with modern browsers.

Adding to @Manohar Reddy solution, firebase Database or firebase RemoteConfig (with Null default value) can be used:

1. Cipher your keys
2. Store it in firebase database
3. Get it during App startup or whenever required
4. decipher keys and use it

What is different in this solution?

• no credintials for firebase
• firebase access is protected so only app with signed certificate have privilege to make API calls
• ciphering/deciphering to prevent middle man interception. However calls already https to firebase

Just check your code in .java class

You had written below line

 mybtn.setOnClickListener(this);

before initializing the mybtn object I mean

mybtn = (Button)findViewById(R.id.mybtn);

just switch this two line or put that line "mybtn.setOnClickListener(this)" after initializing your mybtn object and you will get the answer what you want..

This works good

worksheet.get_Range("A1","A14").Cells.HorizontalAlignment = 
                 Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;

I've used DBDesigner before. It is an open source tool. You might check that out. Not sure if it fits your needs.

Best of luck!

Suppose you have following lines of code

MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)

If you are receiving following error message

AttributeError: module 'urllib' has no attribute 'urlretrieve'

Then you should try following code to fix the issue:

import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)

Hey you can just do one simple thing instead of using model to send parameter use HttpServletRequest object and do this

HttpServletRequest request;
request.setAttribute("param", "value")

now your parametrs will not be shown in your url header hope it works :)

Ensure your encoding is correct for all of your files, this can sometimes happen if you have the encoding wrong for your file or the wrong encoding in your XML header.

So, if I have the following NewFile.xml:

<?xml version="1.0" encoding="UTF-16"?>
<bar foo="foiré" />

And the eclipse encoding is UTF-8:

The encoding of your file, the defined encoding in Eclipse (through Properties->Resource) and the declared encoding in the XML document all need to agree.

The validator is attempting to read the file, expecting <?xml ... but because the encoding is different from that expected, it's not finding it. Hence the error: Content is not allowed in prolog. The prolog is the bit before the <?xml declaration.

EDIT: Sorry, didn't realise that the .xml files were generated and actually contain javascript.

When you suspend the validators, the error messages that you've generated don't go away. To get them to go away, you have to manually delete them.

1. Suspend the validators
2. Click on the 'Content is not allowed in prolog' message, right click and delete. You can select multiple ones, or all of them.
3. Do a Project->Clean. The messages should not come back.

I think that because you've suspended the validators, Eclipse doesn't realise it has to delete the old error messages which came from the validators.

To clarify, a database created under SQL Server 2008 R2 was being opened in an instance of SQL Server 2008 (the version prior to R2). The solution for me was to simply perform an upgrade installation of SQL Server 2008 R2. I can only speak for the Express edition, but it worked.

Oddly, though, the Web Platform Installer indicated that I had Express R2 installed. The better way to tell is to ask the database server itself:

SELECT @@VERSION

So, let me give you sample code:

<div class="news">
Blah, blah, blah. I'm hidden.
</div>

<a class="trigger">Hide/Show News</a>

The link will be the trigger to show the div when clicked. So your Javascript will be:

$('.trigger').click(function() {
   $('.news').toggle();
});

You're almost always better off letting jQuery handle the styling for hiding and showing elements.

Edit: I see people above are recommending using .show and .hide for this. .toggle allows you to do both with just one effect. So that's cool.

(Edit: two previous answers removed, one for answering the question as it stood before edits and one for being, if not absolutely wrong, at least close to it.)

If you compile with debug information on (javac -g), the names of local variables are kept in the .class file. For example, take this simple class:

class TestLocalVarNames {
    public String aMethod(int arg) {
        String local1 = "a string";
        StringBuilder local2 = new StringBuilder();
        return local2.append(local1).append(arg).toString();
    }
}

After compiling with javac -g:vars TestLocalVarNames.java, the names of local variables are now in the .class file. javap's -l flag ("Print line number and local variable tables") can show them.

javap -l -c TestLocalVarNames shows:

The VM spec explains what we're seeing here:

§4.7.9 The LocalVariableTable Attribute:

The LocalVariableTable attribute is an optional variable-length attribute of a Code (§4.7.3) attribute. It may be used by debuggers to determine the value of a given local variable during the execution of a method.

The LocalVariableTable stores the names and types of the variables in each slot, so it is possible to match them up with the bytecode. This is how debuggers can do "Evaluate expression".

As erickson said, though, there's no way to access this table through normal reflection. If you're still determined to do this, I believe the Java Platform Debugger Architecture (JPDA) will help (but I've never used it myself).

Using the sibling selector is the general solution for styling other elements when hovering over a given one, but it works only if the other elements follow the given one in the DOM. What can we do when the other elements should actually be before the hovered one? Say we want to implement a signal bar rating widget like the one below:

This can actually be done easily using the CSS flexbox model, by setting flex-direction to reverse, so that the elements are displayed in the opposite order from the one they're in the DOM. The screenshot above is from such a widget, implemented with pure CSS.

Flexbox is very well supported by 95% of modern browsers.

You can use SSH and SFTP as suggested here.

1. In the Guest OS (Mac OS X), open System Preferences > Sharing, then activate Remote Login; note the ip address specified in the Remote Login instructions, e.g. ssh [email protected]
2. In VirtualBox, open Devices > Network > Network Settings > Advanced > Port Forwarding and specify Host IP = 127.0.0.1, Host Port 2222, Guest IP 10.0.2.15, Guest Port 22
3. On the Host OS, run the following command sftp -P 2222 [email protected]; if you prefer a graphical interface, you can use FileZilla

Replace user and 10.0.2.15 with the appropriate values relevant to your configuration.

I encountered the same problem in VS2013 Ultimate. My problem was that I was creating a Windows Service and forgot to uninstall it. So the Service was running and VS couldn't access one of the DLLs which caused that the whole test suite wasn't loaded at all.

I was facing the same issue when integrating Firebase Cloud Store in my project. Inside the project level gradle, I added

classpath 'com.google.gms:google-services:4.0.1'

that fixed the issue.

• Press Esc to enter 'command mode'
• Use Ctrl+V to enter visual block mode
• Move Up/Downto select the columns of text in the lines you want to comment.
• Then hit Shift+i and type the text you want to insert.
• Then hit Esc, wait 1 second and the inserted text will appear on every line.

For further information and reading, check out "Inserting text in multiple lines" in the Vim Tips Wiki.

When you talked about "Hash Table will place a new entry into the 'next available' bucket if the new Key entry collides with another.", you are talking about the Open addressing strategy of Collision resolution of hash table.

There are several strategies for hash table to resolve collision.

First kind of big method require that the keys (or pointers to them) be stored in the table, together with the associated values, which further includes:

• Separate chaining

• Open addressing

• Coalesced hashing
• Cuckoo hashing
• Robin Hood hashing
• 2-choice hashing
• Hopscotch hashing

Another important method to handle collision is by Dynamic resizing, which further has several ways:

• Resizing by copying all entries
• Incremental resizing
• Monotonic keys

EDIT: the above are borrowed from wiki_hash_table, where you should go to have a look to get more info.

This is not actually a development issue. It happens due to expiration of the Apple Worldwide Developer Relations Intermediate Certificate issued by Apple Worldwide Developer Relations Certificate Authority. WWDRCA issues the certificate to sign your software for Apple devices, allowing our systems to confirm that your software is delivered to users as intended and has not been modified.

To resolve this issue, you have to follow the below steps:

1. Open Keychain Access
2. Go to View -> Show Expired Certificates

3. Go to System in Keychain

4. Here you find that "Apple Worldwide Developer Relations Certificate Authority" is marked as expired. So delete it. Also check under Login Tab and delete expired WWDRCA.

5. Download new WWDR Intermediate Certificate from here(The renewed Apple Worldwide Developer Relations Certification Intermediate Certificate will expire on February 7, 2023).

6. Install it by double clicking on it.

If you still face any issue with your iOS apps, Mac apps, Safari extensions, Apple Wallet and Safari push notifications, then please follow this link of expiration.

The Apple Worldwide Developer Relations Certification Intermediate Certificate expires soon and we've issued a renewed certificate that must be included when signing all new Apple Wallet Passes, push packages for Safari Push Notifications, and Safari Extensions starting February 14, 2016.

While most developers and users will not be affected by the certificate change, we recommend that all developers download and install the renewed certificate on their development systems and servers as a best practice. All apps will remain available on the App Store for iOS, Mac, and Apple TV.

Java has static methods that are associated with classes (e.g. java.lang.Math has only static methods), but the class itself is not static.

I'm assuming you're using jquery to make the AJAX call so you can do this pretty easily by putting the redirect in the success like so:

    $.ajax({
       url: 'ajax_location.html',
       success: function(data) {
          //this is the redirect
          document.location.href='/newpage/';
       }
    });

You cannot type it directly on the browser URL bar.

You can see how POST data is sent on the Internet with Live HTTP Headers for example. Result will be something like that

The hardest part of truncating all tables is removing and re-ading the foreign key constraints.

The following query creates the drop & create statements for each constraint relating to each table name in @myTempTable. If you would like to generate these for all the tables, you may simple use information schema to gather these table names instead.

DECLARE @myTempTable TABLE (tableName varchar(200))
INSERT INTO @myTempTable(tableName) VALUES
('TABLE_ONE'),
('TABLE_TWO'),
('TABLE_THREE')


-- DROP FK Contraints
SELECT 'alter table '+quotename(schema_name(ob.schema_id))+
  '.'+quotename(object_name(ob.object_id))+ ' drop constraint ' + quotename(fk.name) 
  FROM sys.objects ob INNER JOIN sys.foreign_keys fk ON fk.parent_object_id = ob.object_id
  WHERE fk.referenced_object_id IN 
      (
         SELECT so.object_id 
         FROM sys.objects so JOIN sys.schemas sc
         ON so.schema_id = sc.schema_id
         WHERE so.name IN (SELECT * FROM @myTempTable)  AND sc.name=N'dbo'  AND type in (N'U'))


 -- CREATE FK Contraints
 SELECT 'ALTER TABLE [PIMSUser].[dbo].[' +cast(c.name as varchar(255)) + '] WITH NOCHECK ADD CONSTRAINT ['+ cast(f.name as varchar(255)) +'] FOREIGN KEY (['+ cast(fc.name as varchar(255)) +'])
      REFERENCES [PIMSUser].[dbo].['+ cast(p.name as varchar(255)) +'] (['+cast(rc.name as varchar(255))+'])'
FROM  sysobjects f
      INNER JOIN sys.sysobjects c ON f.parent_obj = c.id
      INNER JOIN sys.sysreferences r ON f.id = r.constid
      INNER JOIN sys.sysobjects p ON r.rkeyid = p.id
      INNER JOIN sys.syscolumns rc ON r.rkeyid = rc.id and r.rkey1 = rc.colid
      INNER JOIN sys.syscolumns fc ON r.fkeyid = fc.id and r.fkey1 = fc.colid
WHERE 
      f.type = 'F'
      AND
      cast(p.name as varchar(255)) IN (SELECT * FROM @myTempTable)

I then just copy out the statements to run - but with a bit of dev effort you could use a cursor to run them dynamically.

from itertools import repeat, starmap

results = list(starmap(do, repeat((), 3)))

See the repeatfunc recipe from the itertools module that is actually much more powerful. If you need to just call the method but don't care about the return values you can use it in a for loop:

for _ in starmap(do, repeat((), 3)): pass

but that's getting ugly.

try

persons.GroupBy(x => x.PersonId).Select(x => x)

or

to check if any person is repeating in your list try

persons.GroupBy(x => x.PersonId).Where(x => x.Count() > 1).Any(x => x)

my string

var obj = {"Status":0,"Data":{"guid":"","invitationGuid":"","entityGuid":"387E22AD69-4910-430C-AC16-8044EE4A6B24443545DD"},"Extension":null}

Following code to get guid:

var userObj = JObject.Parse(obj);
var userGuid = Convert.ToString(userObj["Data"]["guid"]);

As explained here, you can use:

function replaceall(str,replace,with_this)
{
    var str_hasil ="";
    var temp;

    for(var i=0;i<str.length;i++) // not need to be equal. it causes the last change: undefined..
    {
        if (str[i] == replace)
        {
            temp = with_this;
        }
        else
        {
                temp = str[i];
        }

        str_hasil += temp;
    }

    return str_hasil;
}

... which you can then call using:

var str = "50.000.000";
alert(replaceall(str,'.',''));

The function will alert "50000000"

Another way to do this on Java 9+ using Stream::iterate(T, Predicate, UnaryOperator):

Stream.iterate(iterator, Iterator::hasNext, UnaryOperator.identity())
        .map(Iterator::next)
        .forEach(System.out::println);

It is a unary "+" operator which yields a numeric expression. It would be the same as d*1, I believe.

Instead of

Object.values(myObject);

use

Object["values"](myObject);

In your example case:

const values = Object["values"](data).map(x => x.substr(0, x.length - 4));

This will hide the ts compiler error.

I'm looking for the fastest way of inserting into Entity Framework

There are some third-party libraries supporting Bulk Insert available:

• Z.EntityFramework.Extensions (Recommended)
• EFUtilities
• EntityFramework.BulkInsert

See: Entity Framework Bulk Insert library

Be careful, when choosing a bulk insert library. Only Entity Framework Extensions supports all kind of associations and inheritances and it's the only one still supported.

Disclaimer: I'm the owner of Entity Framework Extensions

This library allows you to perform all bulk operations you need for your scenarios:

• Bulk SaveChanges
• Bulk Insert
• Bulk Delete
• Bulk Update
• Bulk Merge

Example

// Easy to use
context.BulkSaveChanges();

// Easy to customize
context.BulkSaveChanges(bulk => bulk.BatchSize = 100);

// Perform Bulk Operations
context.BulkDelete(customers);
context.BulkInsert(customers);
context.BulkUpdate(customers);

// Customize Primary Key
context.BulkMerge(customers, operation => {
   operation.ColumnPrimaryKeyExpression = 
        customer => customer.Code;
});

If you put the declaration in a header file, and the definition in a separate .cpp file, and #include the header from a different .cpp file, you will be able to see the difference.

Specifically, suppose:

lib.h

int Add(int a, int b);

lib.cpp

int Add(int a, int b = 3) {
   ...
}

test.cpp

#include "lib.h"

int main() {
    Add(4);
}

The compilation of test.cpp will not see the default parameter declaration, and will fail with an error.

For this reason, the default parameter definition is usually specified in the function declaration:

lib.h

int Add(int a, int b = 3);

Here is the issue

For surfaces it's a bit different than a list of 3-tuples, you should pass in a grid for the domain in 2d arrays.

If all you have is a list of 3d points, rather than some function f(x, y) -> z, then you will have a problem because there are multiple ways to triangulate that 3d point cloud into a surface.

Here's a smooth surface example:

import numpy as np
from mpl_toolkits.mplot3d import Axes3D  
# Axes3D import has side effects, it enables using projection='3d' in add_subplot
import matplotlib.pyplot as plt
import random

def fun(x, y):
    return x**2 + y

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
x = y = np.arange(-3.0, 3.0, 0.05)
X, Y = np.meshgrid(x, y)
zs = np.array(fun(np.ravel(X), np.ravel(Y)))
Z = zs.reshape(X.shape)

ax.plot_surface(X, Y, Z)

ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')

plt.show()

stat appears to do this with the fewest system calls:

$ set debian-live-8.2.0-amd64-xfce-desktop.iso

$ strace stat --format %s $1 | wc
    282    2795   27364

$ strace wc --bytes $1 | wc
    307    3063   29091

$ strace du --bytes $1 | wc
    437    4376   41955

$ strace find $1 -printf %s | wc
    604    6061   64793

The best way is ssh -t user@server "sudo <scriptname>", for example ssh -t user@server "sudo reboot". It will prompt for password for user first and then root(since we are running the script or command with root privilege.

I hope it helped and cleared your doubt.

The SQL WITH clause was introduced by Oracle in the Oracle 9i release 2 database. The SQL WITH clause allows you to give a sub-query block a name (a process also called sub-query refactoring), which can be referenced in several places within the main SQL query. The name assigned to the sub-query is treated as though it was an inline view or table. The SQL WITH clause is basically a drop-in replacement to the normal sub-query.

Syntax For The SQL WITH Clause

The following is the syntax of the SQL WITH clause when using a single sub-query alias.

WITH <alias_name> AS (sql_subquery_statement)
SELECT column_list FROM <alias_name>[,table_name]
[WHERE <join_condition>]

When using multiple sub-query aliases, the syntax is as follows.

WITH <alias_name_A> AS (sql_subquery_statement),
<alias_name_B> AS(sql_subquery_statement_from_alias_name_A
or sql_subquery_statement )
SELECT <column_list>
FROM <alias_name_A>, <alias_name_B> [,table_names]
[WHERE <join_condition>]

In the syntax documentation above, the occurrences of alias_name is a meaningful name you would give to the sub-query after the AS clause. Each sub-query should be separated with a comma Example for WITH statement. The rest of the queries follow the standard formats for simple and complex SQL SELECT queries.

For more information: http://www.brighthub.com/internet/web-development/articles/91893.aspx

Another approach would be to deserialize into a java.util.Map, and then just modify the Java Map as wanted. This separates the Java-side data handling from the data transport mechanism (JSON), which is how I prefer to organize my code: using JSON for data transport, not as a replacement data structure.

You can. Transparent canvas can be quickly faded by using destination-out global composite operation. It's not 100% perfect, sometimes it leaves some traces but it could be tweaked, depending what's needed (i.e. use 'source-over' and fill it with white color with alpha at 0.13, then fade to prepare the canvas).

// Fill canvas using 'destination-out' and alpha at 0.05
ctx.globalCompositeOperation = 'destination-out';
ctx.fillStyle = "rgba(255, 255, 255, 0.05)";
ctx.beginPath();
ctx.fillRect(0, 0, width, height);
ctx.fill();
// Set the default mode.
ctx.globalCompositeOperation = 'source-over';

df.tail(1).index 

seems the most readable

My issue was copying source code to a new machine without pulling over any of the referenced assemblies.

Nothing that I did fixed the error, so in haste, I deleted the BIN directory altogether. Rebuilt my source code, and it worked from then on out.

The previous answers are fine, just adding my preferred way of handling this:

var timePortion = myDate.getTime() % (3600 * 1000 * 24);
var dateOnly = new Date(myDate - timePortion);

If you start with a string, you first need to parse it like so:

var myDate = new Date(dateString);

And if you come across timezone related problems as I have, this should fix it:

var timePortion = (myDate.getTime() - myDate.getTimezoneOffset() * 60 * 1000) % (3600 * 1000 * 24);

This is another regex which I have learned to love/hate over the last week so usually import as (in this case yes) something that reflects how im feeling! make a normal function.... ask for input, then use ....something = re.compile(r'foo*|spam*', yes.I)...... re.I (yes.I below) is the same as IGNORECASE but you cant make as many mistakes writing it!

You then search your message using regex's but honestly that should be a few pages in its own , but the point is that foo or spam are piped together and case is ignored. Then if either are found then lost_n_found would display one of them. if neither then lost_n_found is equal to None. If its not equal to none return the user_input in lower case using "return lost_n_found.lower()"

This allows you to much more easily match up anything thats going to be case sensitive. Lastly (NCS) stands for "no one cares seriously...!" or not case sensitive....whichever

if anyone has any questions get me on this..

    import re as yes

    def bar_or_spam():

        message = raw_input("\nEnter FoO for BaR or SpaM for EgGs (NCS): ") 

        message_in_coconut = yes.compile(r'foo*|spam*',  yes.I)

        lost_n_found = message_in_coconut.search(message).group()

        if lost_n_found != None:
            return lost_n_found.lower()
        else:
            print ("Make tea not love")
            return

    whatz_for_breakfast = bar_or_spam()

    if whatz_for_breakfast == foo:
        print ("BaR")

If you open the Event Log viewer before the event source is created, for example while installing a service, you'll get that error message. You don't need to restart the OS: you simply have to close and open the event viewer.

NOTE: I don't provide a custom messages file. The creation of the event source uses the default configuration, as shown on Matt's answer.

I found this here:

On windows (win xp), the parent process will not finish until the longtask.py has finished its work. It is not what you want in CGI-script. The problem is not specific to Python, in PHP community the problems are the same.

The solution is to pass DETACHED_PROCESS Process Creation Flag to the underlying CreateProcess function in win API. If you happen to have installed pywin32 you can import the flag from the win32process module, otherwise you should define it yourself:

DETACHED_PROCESS = 0x00000008

pid = subprocess.Popen([sys.executable, "longtask.py"],
                       creationflags=DETACHED_PROCESS).pid

<html>
<head>
<script type="text/javascript">
function GetTimeZoneOffset() {
    var d = new Date()
    var gmtOffSet = -d.getTimezoneOffset();
    var gmtHours = Math.floor(gmtOffSet / 60);
    var GMTMin = Math.abs(gmtOffSet % 60);
    var dot = ".";
    var retVal = "" + gmtHours + dot + GMTMin;
    document.getElementById('<%= offSet.ClientID%>').value = retVal;
}

</script>
</head>
<body onload="GetTimeZoneOffset()">
    <asp:HiddenField ID="clientDateTime" runat="server" />
    <asp:HiddenField ID="offSet" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</body>
</html>

key point to notice here is,body has an attribute onload. Just give it a function name and that function will be called on page load.

Alternatively, you can also call the function on page load event like this

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

window.onload = load();

function load() {
    var d = new Date()
    var gmtOffSet = -d.getTimezoneOffset();
    var gmtHours = Math.floor(gmtOffSet / 60);
    var GMTMin = Math.abs(gmtOffSet % 60);
    var dot = ".";
    var retVal = "" + gmtHours + dot + GMTMin;
    document.getElementById('<%= offSet.ClientID%>').value = retVal;
}

</script>
</head>
<body >
    <asp:HiddenField ID="clientDateTime" runat="server" />
    <asp:HiddenField ID="offSet" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></body>
</body>
</html>

In PHP >= 5.3 it can be done like this:

$offerArray = array_map(function($value) {
    return $value[4];
}, $offer);

You did say you had a number-

String.prototype.padZero= function(len, c){
    var s= '', c= c || '0', len= (len || 2)-this.length;
    while(s.length<len) s+= c;
    return s+this;
}
Number.prototype.padZero= function(len, c){
    return String(this).padZero(len,c);
}

In symfony >= 3.2, documentation states that:

An alternative way to get the current user in a controller is to type-hint the controller argument with UserInterface (and default it to null if being logged-in is optional):

use Symfony\Component\Security\Core\User\UserInterface\UserInterface;

public function indexAction(UserInterface $user = null)
{
    // $user is null when not logged-in or anon.
}

This is only recommended for experienced developers who don't extend from the Symfony base controller and don't use the ControllerTrait either. Otherwise, it's recommended to keep using the getUser() shortcut.

Blog post about it

Please note that setting font-sizing with px is not recommended due to accessibility concerns:

"defining font sizes in px is not accessible, because the user cannot change the font size in some browsers. For example, users with limited vision may wish to set the font size much larger than the size chosen by a web designer." (see https://developer.mozilla.org/en-US/docs/Web/CSS/font-size)

A more accessible approach is to set font-size: 100% in the html, which respects user default size settings, and THEN using either percentages or relative units when resizing (em or rem), for example with a @media query.

8 Defensive Programming

8.2 Assertions

An assertion is code that’s used during development—usually a routine or macro—that allows a program to check itself as it runs. When a assertion is true, that means everything is operating as expected. When it’s false, that means it has detected an unexpected error in the code. For example, if the system assumes that a customer-information file will never have more than 50,000 records, the program might contain an assertion that the number of records is less than or equal to 50,000. As long as the number of records is less than or equal to 50,000, the assertion will be silent. If it encounters more than 50,000 records, however, it will loudly “assert” that there is a error in the program.

Assertions are especially useful in large, complicated programs and in high-reliability programs. They enable programmers to more quickly flush out mismatched interface assumptions, errors that creep in when the code is modified, and so on.

An assertion usually takes two arguments: a boolean expression that describes the assumption that’s supposed to be true and a message to display if it isn’t.

(…)

Normally, you don’t want users to see assertion messages in production code; assertions are primarily for use during development and maintenance. Assertions are normally compiled into the code at development time and compiled out of the code for production. During development, assertions flush out contradictory assumptions, unexpected conditions, bad values passed to routines, and so on. During production, they are compiled out of the code so that the assertions don’t degrade system performance.

Yes, Mid.

Dim sub_str
sub_str = Mid(source_str, 10, 5)

The first parameter is the source string, the second is the start index, and the third is the length.

@bobobobo: Note that VBScript strings are 1-based, not 0-based. Passing 0 as an argument to Mid results in "invalid procedure call or argument Mid".

I used the below. The genre element will start where the DJ element ends,

<div>
<div style="width:50%; float:left">DJ</div>
<div>genre</div>
</div>

pardon the inline css.

I myself wondered how I could change the color of the modal-header.

In my solution to the problem I attempted to follow in the path of how my interpretation of the Bootstrap vision was. I added marker classes to tell what the modal dialog box does.

modal-success, modal-info, modal-warning and modal-error tells what they do and you don't trap your self by suddenly having a color you can't use in every situation if you change some of the modal classes in bootstrap. Of course if you make your own theme you should change them.

.modal-success {
  background-image: -webkit-gradient(linear, 0 0, 0 100%, from(#dff0d8), to(#c8e5bc));
  background-image: -webkit-linear-gradient(#dff0d8 0%, #c8e5bc 100%);
  background-image: -moz-linear-gradient(#dff0d8 0%, #c8e5bc 100%);
  background-image: -o-linear-gradient(#dff0d8 0%, #c8e5bc 100%);
  background-image: linear-gradient(#dff0d8 0%, #c8e5bc 100%);
  background-repeat: repeat-x;
  filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#ffdff0d8',     endColorstr='#ffc8e5bc', GradientType=0);
  border-color: #b2dba1;
  border-radius: 6px 6px 0 0;
}

In my solution I actually just copied the styling from alert-success in bootstrap and added the border-radius to keep the rounded corners.

A plunk demonstration of my solution to this problem

The $_GET variable is populated from the parameters set in the URL. From the URL http://example.com/test.php?foo=bar&baz=buzz you can get $_GET['foo'] and $_GET['baz']. So to set these variables, you only have to make a link to that URL.

Recently when working on a web app for a client, I noticed that any click events added to a non-anchor element didn't work on the iPad or iPhone. All desktop and other mobile devices worked fine - but as the Apple products are the most popular mobile devices, it was important to get it fixed.

Turns out that any non-anchor element assigned a click handler in jQuery must either have an onClick attribute (can be empty like below):

onClick=""

OR

The element css needs to have the following declaration:

cursor:pointer

Strange, but that's what it took to get things working again!

you can add an invisible TextView to the FrameLayout.

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:visibility="invisible"
        />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:orientation="horizontal">
        <Button
            android:id="@+id/daily_delete_btn"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:text="DELETE"
            android:layout_gravity="center"/>
        <Button
            android:id="@+id/daily_save_btn"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:text="SAVE"
            android:layout_gravity="center"/>
    </LinearLayout>

if (($value > 1 && $value < 10) || ($value > 20 && $value < 40))

If you only need to look at the existing disks, this one will suffice:

powershell "get-physicaldisk"

Well, I had the same issue and solved with the "bridgeToObjectiveC()" function:

var helloworld = "Hello World!"
var world = helloworld.bridgeToObjectiveC().substringWithRange(NSMakeRange(6,6))
println("\(world)") // should print World!

Please note that in the example, substringWithRange in conjunction with NSMakeRange take the part of the string starting at index 6 (character "W") and finishing at index 6 + 6 positions ahead (character "!")

Cheers.

DEBUG will show all messages, INFO all besides DEBUG messages, and so on.
Usually one uses either INFO or WARN. This dependens on the company policy.

Nesting (and) closures

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

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

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

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

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

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

First, close all instances of Google Chrome. There should be no instances of chrome.exe running in the Windows Task Manager. Then

• Go to %LOCALAPPDATA%\Google\Chrome\User Data\Default\.
• Open the file "Preferences" in a text editor like Notepad.
• First, resave the file to something like "Preference - Old" without any extension (i.e. no .txt). This will serve as a backup, should something go wrong.
• Look for a section called "browser." Inside that section, you should find a subsection called window_placement. Under window_placement you will see things like "bottom", "left", "right", etc. with numbers after them.

You will need to play around with these numbers to get your desired window size and placement. When finished, save this file with the name "Preferences" again with no extension. This will overwrite the existing Preferences file. Open Chrome and see how you did. If you're not satisfied with the size and placement, close Chrome and change the numbers in the Preferences file until you get what you want.

Simply add this

$id = ''; 
if( isset( $_GET['id'])) {
    $id = $_GET['id']; 
} 

If all you need is to ensure uniqueness of elements, then HashSet is what you need.

What do you mean when you say "just a set implementation"? A set is (by definition) a collection of unique elements that doesn't save element order.

gettimeofday - the problem is that will can have lower values if you change you hardware clock (with NTP for example) Boost - not available for this project clock() - usually returns a 4 bytes integer, wich means that its a low capacity, and after some time it returns negative numbers.

I prefer to create my own class and update each 10 miliseconds, so this way is more flexible, and I can even improve it to have subscribers.

class MyAlarm {
static int64_t tiempo;
static bool running;
public:
static int64_t getTime() {return tiempo;};
static void callback( int sig){
    if(running){
        tiempo+=10L;
    }
}
static void run(){ running = true;}
};

int64_t MyAlarm::tiempo = 0L;
bool MyAlarm::running = false;

to refresh it I use setitimer:

int main(){
struct sigaction sa; 
struct itimerval timer; 

MyAlarm::run();
memset (&sa, 0, sizeof (sa)); 
sa.sa_handler = &MyAlarm::callback; 

sigaction (SIGALRM, &sa, NULL); 


timer.it_value.tv_sec = 0; 
timer.it_value.tv_usec = 10000; 



timer.it_interval.tv_sec = 0; 
timer.it_interval.tv_usec = 10000; 


setitimer (ITIMER_REAL, &timer, NULL); 
.....

Look at setitimer and the ITIMER_VIRTUAL and ITIMER_REAL.

Don't use the alarm or ualarm functions, you will have low precision when your process get a hard work.

Because Java bytecode does not retain the names of method or constructor arguments.

Try doing this, there's no special character to concatenate in bash :

mystring="${arg1}12${arg2}endoffile"

explanations

If you don't put brackets, you will ask bash to concatenate $arg112 + $argendoffile (I guess that's not what you asked) like in the following example :

mystring="$arg112$arg2endoffile"

The brackets are delimiters for the variables when needed. When not needed, you can use it or not.

another solution

$ arg1=foo
$ arg2=bar
$ mystring="$arg1"
$ mystring+="12"
$ mystring+="$arg2"
$ mystring+="endoffile"
$ echo "$mystring"
foo12barendoffile

You want the NPGSQL library. Your only other alternative is ODBC.

Good answers by Paul Simon and Steve Homer, I shut down team viewer and that did the trick. Skype or other programs may trigger the same glitch, but in this instance, I recalled the problem occurred when I tried to cut n paste a 2MB file from remote system through windows right click rather than using "File Transfer function in TV. An error message appeared, then the problem with Excel "'Cannot empty clipboard' message.

This problem occurs when you are working on a remote system. After copying and pasting a huge amount of data it shows the error. I have found the solution to this problem.

Go to remote systems task manager and perform the following task

Go to Task Manager > Processes Look for "rdpclip.exe" End that process

Your problem will be solved.

I had faced the same issue because of some dll files were missing from References of VS13. I went to the location http://scn.sap.com/docs/DOC-7824 and installed the newest pack. It resolved the issue.

Just because you're not wrapping the entire request body in JSON, doesn't meant it's not RESTful to use multipart/form-data to post both the JSON and the file(s) in a single request:

curl -F "metadata=<metadata.json" -F "[email protected]" http://example.com/add-file

on the server side:

class AddFileResource(Resource):
    def render_POST(self, request):
        metadata = json.loads(request.args['metadata'][0])
        file_body = request.args['file'][0]
        ...

to upload multiple files, it's possible to either use separate "form fields" for each:

curl -F "metadata=<metadata.json" -F "[email protected]" -F "[email protected]" http://example.com/add-file

...in which case the server code will have request.args['file1'][0] and request.args['file2'][0]

or reuse the same one for many:

curl -F "metadata=<metadata.json" -F "[email protected]" -F "[email protected]" http://example.com/add-file

...in which case request.args['files'] will simply be a list of length 2.

or pass multiple files through a single field:

curl -F "metadata=<metadata.json" -F "[email protected],some-other-file.tar.gz" http://example.com/add-file

...in which case request.args['files'] will be a string containing all the files, which you'll have to parse yourself — not sure how to do it, but I'm sure it's not difficult, or better just use the previous approaches.

The difference between @ and < is that @ causes the file to get attached as a file upload, whereas < attaches the contents of the file as a text field.

P.S. Just because I'm using curl as a way to generate the POST requests doesn't mean the exact same HTTP requests couldn't be sent from a programming language such as Python or using any sufficiently capable tool.

My solution is:

const urlSplit = this._router.url.split('/');
this._router.navigate([urlSplit.splice(0, urlSplit.length - 1).join('/')], { relativeTo: this._route.parent });

And the Router injection:

private readonly _router: Router

To prevent the extra float decimal (i.e. 50.85 - 50 give 0.850000000852), in my case I just need 2 decimals for money cents.

$n = 50.85;
$whole = intval($n);
$fraction = $n * 100 % 100;

Make the sql mode non strict

if using laravel go to config->database, the go to mysql settings and make the strict mode false

I use Google Chart Tools https://developers.google.com/chart/ It's well documented and the charts look great. Being javascript, you can feed it json data via ajax.

You could use:

s = '23.245678'
i = int(float(s))

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate

I use the following to create a temp exact as the table but without the identity:

SELECT TOP 0 CONVERT(INT,0)myid,* INTO #temp FROM originaltable

ALTER TABLE #temp DROP COLUMN id

EXEC tempdb.sys.sp_rename N'#temp.myid', N'id', N'COLUMN'

Gets a warning about renames but no big deal. I use this on production class systems. Helps make sure the copy will follow any future table modifications and the temp produced is capable of getting rows additional times within a task. Please note that the PK constraint is also removed - if you need it you can add it at the end.

You can create an inline view or a temporary table, fill it with you values and issue this:

SELECT  *
FROM    fiberbox f
JOIN    (
        SELECT '%1740%' AS cond
        UNION ALL
        SELECT '%1938%' AS cond
        UNION ALL
        SELECT '%1940%' AS cond
        ) ?
ON      f.fiberBox LIKE cond

This, however, can return you multiple rows for a fiberbox that is something like '1740, 1938', so this query can fit you better:

SELECT  *
FROM    fiberbox f
WHERE   EXISTS
        (
        SELECT  1
        FROM    (
                SELECT '%1740%' AS cond
                UNION ALL
                SELECT '%1938%' AS cond
                UNION ALL
                SELECT '%1940%' AS cond
                ) ?
        WHERE   f.fiberbox LIKE cond
        )

This will work

int word_count(String text,String key){
   int count=0;
   while(text.contains(key)){
      count++;
      text=text.substring(text.indexOf(key)+key.length());
   }
   return count;
}

I hit this challenge today and I found these answers useful but not quite explicit enough for me.

Edit: Just found the Apache Commons Email that wraps this up nicely, meaning you don't need to know below.

If your requirement is an email with:

1. text and html versions
2. html version has embedded (inline) images
3. attachments

The only structure I found that works with Gmail/Outlook/iPad is:

• mixed
  • alternative
    • text
    • related
      • html
      • inline image
      • inline image
  • attachment
  • attachment

Might this be the download you are looking for?

1. Go to the Java SE Downloads Page.
2. Scroll down a tad look for the main table with the header of "Java Platform, Standard Edition"
3. Click the JRE Download Button (JRE is the runtime component. JDK is the developer's kit).
4. Select the appropriate download (all platforms and 32/64 bit downloads are listed)

Just add a break after your ArrayList.remove(A) statement

Do I really have to first convert it into an array of arrays of key-value pairs?

No, an iterator of key-value pair arrays is enough. You can use the following to avoid creating the intermediate array:

function* entries(obj) {
    for (let key in obj)
        yield [key, obj[key]];
}

const map = new Map(entries({foo: 'bar'}));
map.get('foo'); // 'bar'

This line solved my same problem in postgresql:

SELECT DATE_PART('year', column_name::date) from tableName;

If you want month, then simply replacing year with month solves that as well and likewise.

    var EV = {
        ev: '',
        fn: '',
        elem: '',
        add: function () {
            this.elem.addEventListener(this.ev, this.fn, false);
        }
    };

    function cons() {
        console.log('some what');
    }

    EV.ev = 'click';
    EV.fn = cons;
    EV.elem = document.getElementById('body');
    EV.add();

//If you want to add one more listener for load event then simply add this two lines of code:

    EV.ev = 'load';
    EV.add();

Another way to look at this is to simply use another field.

paths:
  root_path: &root
     val: /path/to/root/
  patha: &a
    root_path: *root
    rel_path: a
  pathb: &b
    root_path: *root

I faced a similar issue while copying a sheet to another workbook. I prefer to avoid using 'activesheet' though as it has caused me issues in the past. Hence I wrote a function to perform this inline with my needs. I add it here for those who arrive via google as I did:

The main issue here is that copying a visible sheet to the last index position results in Excel repositioning the sheet to the end of the visible sheets. Hence copying the sheet to the position after the last visible sheet sorts this issue. Even if you are copying hidden sheets.

Function Copy_WS_to_NewWB(WB As Workbook, WS As Worksheet) As Worksheet
    'Creates a copy of the specified worksheet in the specified workbook
    '   Accomodates the fact that there may be hidden sheets in the workbook
    
    Dim WSInd As Integer: WSInd = 1
    Dim CWS As Worksheet
    
    'Determine the index of the last visible worksheet
    For Each CWS In WB.Worksheets
        If CWS.Visible Then If CWS.Index > WSInd Then WSInd = CWS.Index
    Next CWS
    
    WS.Copy after:=WB.Worksheets(WSInd)
    Set Copy_WS_to_NewWB = WB.Worksheets(WSInd + 1)

End Function

To use this function for the original question (ie in the same workbook) could be done with something like...

Set test = Copy_WS_to_NewWB(Workbooks(1), Workbooks(1).Worksheets(1))
test.name = "test sheet name"

EDIT 04/11/2020 from –user3598756 Adding a slight refactoring of the above code

Function CopySheetToWorkBook(targetWb As Workbook, shToBeCopied As Worksheet, copiedSh As Worksheet) As Boolean
    'Creates a copy of the specified worksheet in the specified workbook
    '   Accomodates the fact that there may be hidden sheets in the workbook

    Dim lastVisibleShIndex As Long
    Dim iSh As Long

    On Error GoTo SafeExit
    
    With targetWb
        'Determine the index of the last visible worksheet
        For iSh = .Sheets.Count To 1 Step -1
            If .Sheets(iSh).Visible Then
                lastVisibleShIndex = iSh
                Exit For
            End If
        Next
    
        shToBeCopied.Copy after:=.Sheets(lastVisibleShIndex)
        Set copiedSh = .Sheets(lastVisibleShIndex + 1)
    End With
    
    CopySheetToWorkBook = True
    Exit Function
    
SafeExit:
    
End Function

other than using different (more descriptive?) variable names, the refactoring manily deals with:

1. turning the Function type into a `Boolean while including returned (copied) worksheet within function parameters list this, to let the calling Sub hande possible errors, like

    Dim WB as Workbook: Set WB = ThisWorkbook ' as an example
    Dim sh as Worksheet: Set sh = ActiveSheet ' as an example
    Dim copiedSh as Worksheet
    If CopySheetToWorkBook(WB, sh, copiedSh) Then
        ' go on with your copiedSh sheet
    Else
        Msgbox "Error while trying to copy '" & sh.Name & "'" & vbcrlf & err.Description
    End If
   

2. having the For - Next loop stepping from last sheet index backwards and exiting at first visible sheet occurence, since we're after the "last" visible one

Create a temporary element (e. g. DIV), assign your HTML code to its innerHTML property, and then append its child nodes to the HEAD element one by one. For example, like this:

var temp = document.createElement('div');

temp.innerHTML = '<link rel="stylesheet" href="example.css" />'
               + '<script src="foobar.js"><\/script> ';

var head = document.head;

while (temp.firstChild) {
    head.appendChild(temp.firstChild);
}

Compared with rewriting entire HEAD contents via its innerHTML, this wouldn’t affect existing child elements of the HEAD element in any way.

Note that scripts inserted this way are apparently not executed automatically, while styles are applied successfully. So if you need scripts to be executed, you should load JS files using Ajax and then execute their contents using eval().

There is no defined maximum size for HTTP POST requests. If you notice such a limit then it's an arbitrary limitation of your HTTP Server/Client.

You might get a better answer if you tell how big the XML is.

I've been wrestling with Magento for the last month or so and I'm still trying to figure it out. So this is a case of the blind leading the blind. There's little in the way of documentation and the forum/wiki is chaotic at best. Not only that, but there are several solutions that are either outdated or far from optimal. I'm not sure if you have a project or just trying to figure it out, but it's probably easier if you started with modifying existing functionality as opposed to creating something completely new. For that I'd definately go with the "Recommended articles for developers" in the wiki. The new payment method one was a real eye-opener.

For debugging I'd definitely recommend using FirePHP and looking at your HTML source when something goes wrong. The ole echo debug method doesn't really work all that well.

The general architecture is so mind-numbingly complex, that even if I completely understood it, I'd need to write a book to cover it. The best I can do is give you advice I wish someone had given me when I first started...

Stay away from core files. Don't modify them, instead write your own module and override what you need.

Magento uses config files consisting of XML to decide what it needs to do. In order to get it to run your own stuff as opposed to core functionality you need the correct xml. Unfortunately there is no guide on how to build you XML; you need to look at examples and do some serious testing. To complicate things the content of these files is largely case-sensitive. However if you master these you can override any part of the basic functionality which makes for a very powerful system.

Magento uses methods like Mage::getModel('mymodel'), Mage::getSingleton('mysingleton'), Mage::helper('myhelper') to return objects of certain classes. It finds these by default in its core namespace. If you want it to use your own, you need to override these in your config.xml file.

The name of your classes must correspond to the folder they're in.

A lot of the objects in Magento ultimately extend something called a Varien_Object. This is a general purpose class (kind of like a swiss army knife) and its purpose in life is to allow you to define your own methods/variables on the fly. For example you'll see it used as a glorified array to pass data from one method to another.

During development make sure you caching is disabled. It'll make magento excruciatingly slow, but it'll save you a lot of head trauma (from banging it on your desk).

You'll see $this being used a lot. It means a different class depending on what file you see it. get_class($this) is your friend, especially in conjunction with FirePHP.

Jot things down on paper. A lot. There are countless little factoids that you're gonna need 1-2 days after you encounter them.

Magento loves OO. Don't be surprised if tracing a method takes you through 5-10 different classes.

Read the designer's guide here. It's meant mostly for graphics designers, but you need it to understand where and why the output from your module will end up. For that don't forget to turn on "Template path hints" in the developer section of the admin panel.

There's more, but I'll stop here before this turns into a dissertation.

I like a solution to allow multiple Instances, if the exe is called from an other path. I modified CharithJ solution Method 1:

   static class Program {
    [DllImport("user32.dll")]
    private static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);
    [DllImport("User32.dll")]
    public static extern Int32 SetForegroundWindow(IntPtr hWnd);
    [STAThread]
    static void Main() {
        Process currentProcess = Process.GetCurrentProcess();
        foreach (var process in Process.GetProcesses()) {
            try {
                if ((process.Id != currentProcess.Id) && 
                    (process.ProcessName == currentProcess.ProcessName) &&
                    (process.MainModule.FileName == currentProcess.MainModule.FileName)) {
                    ShowWindow(process.MainWindowHandle, 5); // const int SW_SHOW = 5; //Activates the window and displays it in its current size and position. 
                    SetForegroundWindow(process.MainWindowHandle);
                    return;
                }
            } catch (Exception ex) {
                //ignore Exception "Access denied "
            }
        }

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new Form1());
    }
}

Here's a flowchart based on this answer. See also, using script to emulate a terminal.

As it is written before, some folders (/META-INF/resources/, /resources/, /static/, /public/) serve static content by default, conroller misconfiguration can break this behaviour.

It is a common pitfall that people define the base url of a controller in the @RestController annotation, instead of the @RequestMapping annotation on the top of the controllers.

This is wrong:

@RestController("/api/base")
public class MyController {

    @PostMapping
    public String myPostMethod( ...) {

The above example will prevent you from opening the index.html. The Spring expects a POST method at the root, because the myPostMethod is mapped to the "/" path.

You have to use this instead:

@RestController
@RequestMapping("/api/base")
public class MyController {

    @PostMapping
    public String myPostMethod( ...) {

Re: changing opts to theme etc (for lazy folks):

theme(axis.line=element_blank(),
      axis.text.x=element_blank(),
      axis.text.y=element_blank(),
      axis.ticks=element_blank(),
      axis.title.x=element_blank(),
      axis.title.y=element_blank(),
      legend.position="none",
      panel.background=element_blank(),
      panel.border=element_blank(),
      panel.grid.major=element_blank(),
      panel.grid.minor=element_blank(),
      plot.background=element_blank())

For those who understand the bias problem but can't stand the unpredictable run-time of rejection-based methods, this series produces a progressively less biased random integer in the [0, n-1] interval:

r = n / 2;
r = (rand() * n + r) / (RAND_MAX + 1);
r = (rand() * n + r) / (RAND_MAX + 1);
r = (rand() * n + r) / (RAND_MAX + 1);
...

It does so by synthesising a high-precision fixed-point random number of i * log_2(RAND_MAX + 1) bits (where i is the number of iterations) and performing a long multiplication by n.

When the number of bits is sufficiently large compared to n, the bias becomes immeasurably small.

It does not matter if RAND_MAX + 1 is less than n (as in this question), or if it is not a power of two, but care must be taken to avoid integer overflow if RAND_MAX * n is large.

pixelbits answer is correct and you should always use .then() to access the value of a promise in production code.

However, there is a way to access the promise's value directly after it has been resolved by using the following unsupported internal node.js binding:

process.binding('util').getPromiseDetails(myPromise)[1]

WARNING: process.binding was never meant to be used outside of nodejs core and the nodejs core team is actively looking to deprecate it

https://github.com/nodejs/node/pull/22004 https://github.com/nodejs/node/issues/22064

I think that the answer you are looking for is:

plot(first thing to plot)
plot(second thing to plot,add=TRUE)

If you need to work a lot with database in your code and you know the structure of your table, I suggest you do it as follow:

First of all you can define a class which will help you to make objects capable of keeping your table rows data. For example in my project I created a class named Document.java to keep data of a single document from my database and I made an array list of these objects to keep data of my table which is gain by a query.

Second of all, you can define a class to handle your database needs. For example I defined a class named DataBase.java which handles my connections to the database and my needed queries. And I instantiated an objected of it in my main class.

I hope this could be a little help.

You can't do it using environment variables directly. You need to use the set of "non standard" options that are passed to the java command. Run: java -X for details. The options you're looking for are -Xmx and -Xms (this is "initial" heap size, so probably what you're looking for.)

Some products like Ant or Tomcat might come with a batch script that looks for the JAVA_OPTS environment variable, but it's not part of the Java runtime. If you are using one of those products, you may be able to set the variable like:

set JAVA_OPTS="-Xms128m -Xmx256m"  

You can also take this approach with your own command line like:

set JAVA_OPTS="-Xms128m -Xmx256m"  
java ${JAVA_OPTS} MyClass

Set the user name as data-username attribute to the button and also a class:

HTML

<input type="button" name="theButton" value="Detail" class="btn" data-username="{{result['username']}}" />

JS

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name != undefined && name != null) {
        window.location = '/player_detail?username=' + name;
    }
});?

EDIT:

Also, you can simply check for undefined && null using:

$(document).on('click', '.btn', function() {

    var name = $(this).data('username');        
    if (name) {
        window.location = '/player_detail?username=' + name;
    }
});?

As, mentioned in this answer

if (name) {            
}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ("")
• 0
• false

The above list represents all possible falsy values in ECMA/Javascript.

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

An AXD file is a file used by ASP.NET applications for handling embedded resource requests. It contains instructions for retrieving embedded resources, such as images, JavaScript (.JS) files, and.CSS files. AXD files are used for injecting resources into the client-side webpage and access them on the server in a standard way.

$(document).ready happens when all the elements are present in the DOM, but not necessarily all content.

$(document).ready(function() {
    alert("document is ready");
});

window.onload or $(window).load() happens after all the content resources (images, etc) have been loaded.

$(window).load(function() {
    alert("window is loaded");
});

Here is another nice clean option that does not require changing your pattern.

        var text = "example-123-example";
        var pattern = @"-(\d+)-";

        var replaced = Regex.Replace(text, pattern, (_match) =>
        {
            Group group = _match.Groups[1];
            string replace = "AA";
            return String.Format("{0}{1}{2}", _match.Value.Substring(0, group.Index - _match.Index), replace, _match.Value.Substring(group.Index - _match.Index + group.Length));
        });

By design there is no simple way to turn on or turn off the identity feature for an existing column. The only clean way to do this is to create a new column and make it an identity column or create a new table and migrate your data.

If we use SQL Server Management Studio to get rid of the identity value on column "id", a new temporary table is created, the data is moved to the temporary table, the old table is dropped and the new table is renamed.

Use Management Studio to make the change and then right click in the designer and select "Generate Change Script".

You will see that this is what SQL server in doing in the background.

Just worked this for me : Install-Package System.Data.SQLite.Core on Package Manager Console.

To avoid possible overlapping of execution, use a locking mechanism as described in that thread.

First get rid of existing duplicates

delete a from votes as a, votes as b where a.id < b.id 
and a.user <=> b.user and a.email <=> b.email 
and a.address <=> b.address;

Then add the unique constraint

ALTER TABLE votes ADD UNIQUE unique_index(user, email, address);

Verify the constraint with

SHOW CREATE TABLE votes;

Note that user, email, address will be considered unique if any of them has null value in it.

jquery

    $('#select_id').change(function(){
    // selected value 
    alert($(this).val());
    // selected text 
    alert($(this).find("option:selected").text());
})

html

<select onchange="test()" id="select_id">
    <option value="0">-Select-</option>
    <option value="1">Communication</option>
</select>

$("li").click(function(){
    alert($(this).attr("class"));
});

Answer given by user @JPM and @usman are really very useful. It works fine but in my case it come in onReceive multiple time in my case 4 times so my code execute multiple time.

I do some modification and make as per my requirement and now it comes only 1 time

Here is java class for Broadcast.

public class WifiReceiver extends BroadcastReceiver {

String TAG = getClass().getSimpleName();
private Context mContext;

@Override
public void onReceive(Context context, Intent intent) {

    mContext = context;


    if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {

        ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = cm.getActiveNetworkInfo();

        if (networkInfo != null && networkInfo.getType() == ConnectivityManager.TYPE_WIFI &&
                networkInfo.isConnected()) {
            // Wifi is connected
            WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
            WifiInfo wifiInfo = wifiManager.getConnectionInfo();
            String ssid = wifiInfo.getSSID();

            Log.e(TAG, " -- Wifi connected --- " + " SSID " + ssid );

        }
    }
    else if (intent.getAction().equalsIgnoreCase(WifiManager.WIFI_STATE_CHANGED_ACTION))
    {
        int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_UNKNOWN);
        if (wifiState == WifiManager.WIFI_STATE_DISABLED)
        {
            Log.e(TAG, " ----- Wifi  Disconnected ----- ");
        }

    }
}
}

In AndroidManifest

<receiver android:name=".util.WifiReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.net.wifi.WIFI_STATE_CHANGED" />
            <action android:name="android.net.conn.CONNECTIVITY_CHANGE"/>
        </intent-filter>
    </receiver>


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

If by all permissions you mean 777

Navigate to folder and

chmod -R 777 .

You need to read about Java Image API and mouse-related API, maybe somewhere under the java.awt.event package.

For a start, you need to be able to load and display the image to the screen, maybe you'll use a JPanel.

Then from there, you will try implement a mouse motion listener interface and other related interfaces. Maybe you'll get tied on the mouseDragged method...

For a mousedragged action, you will get the coordinate of the rectangle form by the drag...

Then from these coordinates, you will get the subimage from the image you have and you sort of redraw it anew....

And then display the cropped image... I don't know if this will work, just a product of my imagination... just a thought!

For me I had to move Logger to a Nuget Package. Below code need to be added in NuGet package project.

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config")]

See https://gurunadhduvvuru.wordpress.com/2020/04/30/log4net-issues-when-moved-it-to-a-nuget-package/ for more details.

For anyone wondering, the index in the getStackTrace()[3] method signals the amount of threads the triggering line travels until the actual .getStackTrace() method excluding the executing line.

This means that if the Thread.currentThread().getStackTrace()[X].getLineNumber(); line is executed from 3 nested methods above, the index number must be 3.

Example:

First layer

private static String message(String TAG, String msg) {

    int lineNumber = Thread.currentThread().getStackTrace()[3].getLineNumber();

    return ".(" + TAG + ".java:"+ lineNumber +")" + " " + msg;
}

Second Layer

private static void print(String s) {
        System.out.println(s);
}

Third Layer

public static void normal(
        String TAG,
        String message
) {
    print(
            message(
                    TAG,
                    message
            )
    );
}

Executing Line:

    Print.normal(TAG, "StatelessDispatcher");

As someone that has not received any formal education on IT, this has been mind opening on how compilers work.

You can simply specify a series of images like this:

\includegraphics<1>{A}
\includegraphics<2>{B}
\includegraphics<3>{C}

This will produce three slides with the images A to C in exactly the same position.

nFilter.style.width = '330px';
nFilter.style.float = 'left';

This should add an inline style to the element.

I viewed the Eclipse ADT documentation and found out the way to get around this issue. I was able to Update My SDK Tool to 22.0.4 (Latest Version).

Solution is: First Update ADT to 22.0.4(Latest version) and then Update SDK Tool to 22.0.4(Latest Version)

The above link says,

ADT 22.0.4 is designed for use with SDK Tools r22.0.4. If you haven't already installed SDK Tools r22.0.4 into your SDK, use the Android SDK Manager to do so

What I had to do was update my ADT to 22.0.4 (Latest Version) and then I was able to update SDK tool to 22.0.4. I thought only SDK Tool has been updated not ADT, so I was updating the SDK Tool with Older ADT Version (22.0.1).

How to Update your ADT to Latest Version

1. In Eclipse go to Help
2. Install New Software ---> Add
3. inside Add Repository write the Name: ADT (or whatever you want)
4. and Location: https://dl-ssl.google.com/android/eclipse/
5. after loading you should get Developer Tools and NDK Plugins
6. check both if you want to use the Native Developer Kit (NDK) in the future or check Developer Tool only
7. click Next
8. Finish

Yes, see "Loading Page Fragments" on http://api.jquery.com/load/.

In short, you add the selector after the URL. For example:

$('#result').load('ajax/test.html #container');

Linux does not have any system variables that give the current CPU utilization. Instead, you have to read /proc/stat several times: each column in the cpu(n) lines gives the total CPU time, and you have to take subsequent readings of it to get percentages. See this document to find out what the various columns mean.

These are taken from my open source library, aFileChooser.

If you are using pip 19.0.3 and python 3.7.4. Then go for pip list command in your virtualenv. It will show all the installed packages with respective versions.

Try this to check

$('#captureImage').attr("checked",true).checkboxradio("refresh");

and uncheck

$('#captureImage').attr("checked",false).checkboxradio("refresh");  

Windows solution: Assuming all files contained in sub-directory 'src', and you want to compile them to 'bin'.

for /r src %i in (*.java) do javac %i -sourcepath src -d bin

If src contains a .java file immediately below it then this is faster

javac src\\*.java -d bin

There's many different ways to go about this, but I'm partial to describeBy in the psych package:

describeBy(df$dt, df$group, mat = TRUE) 

For me I was getting the problem when deploying a geoserver WAR into tomcat 7

To fix it, I was on Java 7 and upgrading to Java 8.

This is running under a docker container. Tomcat 7.0.75 + Java 8 + Geos 2.10.2

you could either use

SELECT PARSENAME('$'+ Convert(varchar,Convert(money,@MoneyValue),1),2)

or

SELECT CurrencyNoDecimals = '$'+ LEFT( CONVERT(varchar, @MoneyValue,1),    
       LEN (CONVERT(varchar, @MoneyValue,1)) - 2)

Going further with the rev-list option, if you want to find the most recent merge commit from your master branch into your production branch (as a purely hypothetical example):

git checkout `git rev-list -n 1 --merges --first-parent --before="2012-01-01" production`

I needed to find the code that was on the production servers as of a given date. This found it for me.
