Found that setting the secure property in Session_Start is sufficient, as recommended in MSDN blog "Securing Session ID: ASP/ASP.NET" with some augmentation.

    protected void Session_Start(Object sender, EventArgs e)
    {
        SessionStateSection sessionState = 
 (SessionStateSection)ConfigurationManager.GetSection("system.web/sessionState");
        string sidCookieName = sessionState.CookieName;

        if (Request.Cookies[sidCookieName] != null)
        {
            HttpCookie sidCookie = Response.Cookies[sidCookieName];
            sidCookie.Value = Session.SessionID;
            sidCookie.HttpOnly = true;
            sidCookie.Secure = true;
            sidCookie.Path = "/";
        }
    }

With this library here you can sort the list of custom objects on multiple columns. The library uses version 8.0 features. Sample is also available there. Here is a sample to do

SortKeys sortKeys = new SortKeys();
sortKeys.addField("firstName")
            .addField("age", true); // This (true) will sort the age descending

// Other ways to specify a property to the sorter are
//      .addField("lastName", String.class);
//      .addField("dob", Date.class, true);

// Instantiate a ListSorter
ListSorter listSorter = new ListSorter();

// Pass the data to sort (listToSort) and the "by keys" to sort (sortKeys)
List sortedList = (List<Person>) listSorter.sortList(listToSort, sortKeys);

Example using Array.filter:

var str = 'a,b,hi,ma,n,yu';

var strArr = Array.prototype.filter.call(str, eachChar => eachChar !== ',');

if the applications are C#, you can use ClickOnce deployment, which is a good option if you can't guarentee the user will have the app, however you'll have to re-build the apps with deployment options and grab some boilerplate code from each project.

You can also use Javascript.

Or you can register an application to handle a new web protocol you can define. This could also be an "app selection" protocol, so each time an app is clicked it would link to a page on your new protocol, all handling of this protocol is then passed to your "selection app" which uses arguments to find and launch an app on the clients PC.

Consolidating the caveats mentioned in comments/answers for several use cases.

Mostly, see http://docs.telerik.com/fiddler/Configure-Fiddler/Tasks/ConfigureDotNETApp

• Start Fiddler before your app

• In a console app, you might not need to specify the proxyaddress:

  <proxy bypassonlocal="False" usesystemdefault="True" />
  

• In a web application / something hosted in IIS, you need to add the proxyaddress:

  <proxy bypassonlocal="False" usesystemdefault="True" proxyaddress="http://127.0.0.1:8888" />
  

• When .NET makes a request (through a service client or HttpWebRequest, etc) it will always bypass the Fiddler proxy for URLs containing localhost, so you must use an alias like the machine name or make up something in your 'hosts' file (which is why something like localhost.fiddler or http://HOSTNAME works)

• If you specify the proxyaddress, you must remove it from your config if Fiddler isn't on, or any requests your app makes will throw an exception like:

  No connection could be made because the target machine actively refused it 127.0.0.1:8888

• Don't forget to use config transformations to remove the proxy section in production

Unique Key (UK): It's a column or a group of columns that can identify a uniqueness in a row.

Primary Key (PK): It's also a column or group of columns that can identify a uniqueness in a row.

So the Primary key is just another name for unique key, but the default implementation in SQL Server is different for Primary and Unique Key.

By Default:

1. PK creates a Clustered index and UK creates a Non Clustered Index.
2. PK is not null, but UK allows nulls (Note: By Default)
3. There can only be one and only one PK on a table, but there can be multiple UK's
4. You can override the default implementation depending upon your need.

It really depends what is your aim when deciding whether to create a UK or PK. It follows an analogy like "If there is a team of three people, so all of them are peers, but there will be one of them who will be a pair of peers: PK and UK has similar relation.". I would suggest reading this article: The example given by the author may not seem suitable, but try to get an overall idea.

First read the image as an array

image = plt.imread(//image_path)
plt.imshow(image)

If you use make generators like cmake, JUCE, etc. try to set a correct VS version target (2013, 2015, 2017) and regenerate the solution again.

If you are using Gradle for your builds - there is a Gradle plugin which allows you to add aar dependency to your java|kotlin|scala|... modules.

https://github.com/stepango/aar2jar

plugins {
    id 'java'
    id 'com.stepango.aar2jar' version “0.6” // <- this one
}

dependencies {
    compileOnlyAar "com.android.support:support-annotations:28.0.0" // <- Use any AAR dependencies
}

Or you might be looking at this question because you happened to make a silly typo like I did and have the =~ reversed to ~=

you can use this command

pg_dump --table=yourTable --data-only --column-inserts yourDataBase > file.sql

you should change yourTable, yourDataBase to your case

Example for replacing LI elements

function (element) {
    let li = element.parentElement;
    let ul = li.parentNode;   
    if (li.nextSibling.nodeName === 'LI') {
        let li_replaced = ul.replaceChild(li, li.nextSibling);
        ul.insertBefore(li_replaced, li);
    }
}

Many way to Json Parse but i have found most effective way to

 @model  List<string[]>

     <script>

         function DataParse() {
             var model = '@Html.Raw(Json.Encode(Model))';
             var data = JSON.parse(model);  

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

     </script>

Use Underscore _.reject():

arr = _.reject(arr, function(d){ return d.id === 3; });

You need to use JSON.stringify to first serialize your object to JSON, and then specify the contentType so your server understands it's JSON. This should do the trick:

$.ajax({
    url: url,
    type: "POST",
    data: JSON.stringify(data),
    contentType: "application/json",
    complete: callback
});

Note that the JSON object is natively available in browsers that support JavaScript 1.7 / ECMAScript 5 or later. If you need legacy support you can use json2.

This worked for me on Windows Server 2012 - I needed to export a non-exportable certificate to setup another ADFS server and this did the trick. Remember to use the jailbreak instructions above i.e.:

crypto::certificates /export /systemstore:CERT_SYSTEM_STORE_LOCAL_MACHINE

You can use it in the same datafram (df) using the previously provided code

df[!grepl("REVERSE", df$Name),]

or you might assign a different name to the datafram using this code

df1<-df[!grepl("REVERSE", df$Name),]

I use eval to solve this problem.

For example:

    function regex_exec() {

        // Important! Like @Samuel Faure mentioned, Eval on user input is a crazy security risk, so before use this method, please take care of the security risk. 
        var regex = $("#regex").val();

        // eval()
        var patt = eval(userInput);

        $("#result").val(patt.exec($("#textContent").val()));
    }

Many possibilities...

You know how to generate randomly an integer right? You can thus generate a char from it... (ex 65 -> A)

It depends what you need, the level of randomness, the security involved... but for a school project i guess getting UUID substring would fit :)

As of Select2 4.1, they've removed support for .enable

$("select").prop("disabled", true); // instead of $("select").enable(false);

From: https://select2.org/upgrading/migrating-from-35

Try the following code. The value you are looking for is stored on a GuidAttribute instance attached to the Assembly

using System.Runtime.InteropServices;

static void Main(string[] args)
{
    var assembly = typeof(Program).Assembly;
    var attribute = (GuidAttribute)assembly.GetCustomAttributes(typeof(GuidAttribute),true)[0];
    var id = attribute.Value;
    Console.WriteLine(id);
}

  try {
        $result=DB::table('users')->whereExists(function ($Query){
            $Query->where('id','<','14162756');
            $Query->whereBetween('password',[14162756,48384486]);
            $Query->whereIn('id',[3,8,12]);
        });
    }catch (\Exception $error){
        Log::error($error);
        DB::rollBack(1);
        return redirect()->route('bye');
    }

I needed to ensure values can still be entered with a comma instead of a point as a decimal separator. This seems to be an age-old problem. Background info can be found following these links:

• https://www.slightfuture.com/webdev/html5-input-number-localization.html
• https://codepen.io/aminimalanimal/full/bdOzRG

I finally solved it with a little bit of jQuery. Replacing the commas with dots onChange. This seems to be working good so far in latest Firefox, Chrome and Safari.

$('input[type=number]').each(function () {

  $(this).change(function () {

    var $replace = $(this).val().toString().replace(/,/g, '.');

    $(this).val($replace);

  })

});

When to use dt accessor

A common source of confusion revolves around when to use .year and when to use .dt.year.

The former is an attribute for pd.DatetimeIndex objects; the latter for pd.Series objects. Consider this dataframe:

df = pd.DataFrame({'Dates': pd.to_datetime(['2018-01-01', '2018-10-20', '2018-12-25'])},
                  index=pd.to_datetime(['2000-01-01', '2000-01-02', '2000-01-03']))

The definition of the series and index look similar, but the pd.DataFrame constructor converts them to different types:

type(df.index)     # pandas.tseries.index.DatetimeIndex
type(df['Dates'])  # pandas.core.series.Series

The DatetimeIndex object has a direct year attribute, while the Series object must use the dt accessor. Similarly for month:

df.index.month               # array([1, 1, 1])
df['Dates'].dt.month.values  # array([ 1, 10, 12], dtype=int64)

A subtle but important difference worth noting is that df.index.month gives a NumPy array, while df['Dates'].dt.month gives a Pandas series. Above, we use pd.Series.values to extract the NumPy array representation.

for (var i in a) {
   console.log(a[i],i)
}

I ran into this issue with the Oracle 11R2 client. Not sure if the Oracle installer did this or someone did it here before i arrived. It was not 64-bit vs 32-bit, all was 64-bit.

The error was that libexpat.so.1 was not a symbolic link.

It turned out that there were two identical files, libexpat.so.1.5.2 and libexpat.so.1. Removing the offending file and making it a symlink to the 1.5.2 version caused the error to go away.

Makes sense that you'd want the well-known name to be a symlink to the current version. If you do this, it's less likely that you'll end up with a stale library.

I had a similar problem. I was using Boostrap in conjunction with Backbone, and I was capturing clicks of the "Do it" button, and then stopping propagation of those events. Bizarrely, this made the modal go away, but not the background. If I call event.preventDefault() but do not call stopPropagation(), it all works fine.

You want to process the data from an HTML form in a servlet. "

You could use the @Rule annotation with ExpectedException, like this:

@Rule
public ExpectedException expectedEx = ExpectedException.none();

@Test
public void shouldThrowRuntimeExceptionWhenEmployeeIDisNull() throws Exception {
    expectedEx.expect(RuntimeException.class);
    expectedEx.expectMessage("Employee ID is null");

    // do something that should throw the exception...
    System.out.println("=======Starting Exception process=======");
    throw new NullPointerException("Employee ID is null");
}

Note that the example in the ExpectedException docs is (currently) wrong - there's no public constructor, so you have to use ExpectedException.none().

private void Test_Click(object sender, System.EventArgs e){
   string path;
   path = System.IO.Path.GetDirectoryName( 
      System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase );
    Console.WriiteLine( path );  
}

you have to include two more jar files.

xmlbeans-2.3.0.jar and dom4j-1.6.1.jar Add try it will work.

Note: It is required for the files with .xlsx formats only, not for just .xlt formats.

I've investigated this issue, referring to the LayoutInflater docs and setting up a small sample demonstration project. The following tutorials shows how to dynamically populate a layout using LayoutInflater.

Before we get started see what LayoutInflater.inflate() parameters look like:

• resource: ID for an XML layout resource to load (e.g., R.layout.main_page)
• root: Optional view to be the parent of the generated hierarchy (if attachToRoot is true), or else simply an object that provides a set of LayoutParams values for root of the returned hierarchy (if attachToRoot is false.)

• attachToRoot: Whether the inflated hierarchy should be attached to the root parameter? If false, root is only used to create the correct subclass of LayoutParams for the root view in the XML.

• Returns: The root View of the inflated hierarchy. If root was supplied and attachToRoot is true, this is root; otherwise it is the root of the inflated XML file.

Now for the sample layout and code.

Main layout (main.xml):

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</LinearLayout>

Added into this container is a separate TextView, visible as small red square if layout parameters are successfully applied from XML (red.xml):

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="25dp"
    android:layout_height="25dp"
    android:background="#ff0000"
    android:text="red" />

Now LayoutInflater is used with several variations of call parameters

public class InflaterTest extends Activity {

    private View view;

    @Override
    public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      setContentView(R.layout.main);
      ViewGroup parent = (ViewGroup) findViewById(R.id.container);

      // result: layout_height=wrap_content layout_width=match_parent
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view);

      // result: layout_height=100 layout_width=100
      view = LayoutInflater.from(this).inflate(R.layout.red, null);
      parent.addView(view, 100, 100);

      // result: layout_height=25dp layout_width=25dp
      // view=textView due to attachRoot=false
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, false);
      parent.addView(view);

      // result: layout_height=25dp layout_width=25dp 
      // parent.addView not necessary as this is already done by attachRoot=true
      // view=root due to parent supplied as hierarchy root and attachRoot=true
      view = LayoutInflater.from(this).inflate(R.layout.red, parent, true);
    }
}

The actual results of the parameter variations are documented in the code.

SYNOPSIS: Calling LayoutInflater without specifying root leads to inflate call ignoring the layout parameters from the XML. Calling inflate with root not equal null and attachRoot=true does load the layout parameters, but returns the root object again, which prevents further layout changes to the loaded object (unless you can find it using findViewById()). The calling convention you most likely would like to use is therefore this one:

loadedView = LayoutInflater.from(context)
                .inflate(R.layout.layout_to_load, parent, false);

To help with layout issues, the Layout Inspector is highly recommended.

To Enter into crontab :

crontab -e

write this into the file:

0 */2 * * * python/php/java yourfilepath

Example :0 */2 * * * python ec2-user/home/demo.py

and make sure you have keep one blank line after the last cron job in your crontab file

(^(\s*?\,+)+\s?)|(^\s+)|(\s+$)|((\s*?\,+)+\s?$)

You might want to use helper library like http://momentjs.com/ which wraps the native javascript date object for easier manipulations

Then you can do things like:

var day = moment("12-25-1995", "MM-DD-YYYY");

or

var day = moment("25/12/1995", "DD/MM/YYYY");

then operate on the date

day.add('days', 7)

and to get the native javascript date

day.toDate();

Actually a new line in a SQL command or script string can be any of CR, LF or CR+LF. To get them all, you need something like this:

SELECT REPLACE(REPLACE(@str, CHAR(13), ''), CHAR(10), '')

How PHP handles sessions is quite confusing for beginners to understand. This might help them by giving an overview of how sessions work: how sessions work(custom-session-handlers)

Call second ajax from 'complete'

Here is the example

   var dt='';
   $.ajax({
    type: "post",
    url: "ajax/example.php",
    data: 'page='+btn_page,
    success: function(data){
        dt=data;
        /*Do something*/
    },
    complete:function(){
        $.ajax({
           var a=dt; // This line shows error.
           type: "post",
           url: "example.php",
           data: 'page='+a,
           success: function(data){
              /*do some thing in second function*/
           },
       });
    }
});

Shuffle any (I)List with an extension method based on the Fisher-Yates shuffle:

private static Random rng = new Random();  

public static void Shuffle<T>(this IList<T> list)  
{  
    int n = list.Count;  
    while (n > 1) {  
        n--;  
        int k = rng.Next(n + 1);  
        T value = list[k];  
        list[k] = list[n];  
        list[n] = value;  
    }  
}

Usage:

List<Product> products = GetProducts();
products.Shuffle();

The code above uses the much criticised System.Random method to select swap candidates. It's fast but not as random as it should be. If you need a better quality of randomness in your shuffles use the random number generator in System.Security.Cryptography like so:

using System.Security.Cryptography;
...
public static void Shuffle<T>(this IList<T> list)
{
    RNGCryptoServiceProvider provider = new RNGCryptoServiceProvider();
    int n = list.Count;
    while (n > 1)
    {
        byte[] box = new byte[1];
        do provider.GetBytes(box);
        while (!(box[0] < n * (Byte.MaxValue / n)));
        int k = (box[0] % n);
        n--;
        T value = list[k];
        list[k] = list[n];
        list[n] = value;
    }
}

A simple comparison is available at this blog (WayBack Machine).

Edit: Since writing this answer a couple years back, many people have commented or written to me, to point out the big silly flaw in my comparison. They are of course right. There's nothing wrong with System.Random if it's used in the way it was intended. In my first example above, I instantiate the rng variable inside of the Shuffle method, which is asking for trouble if the method is going to be called repeatedly. Below is a fixed, full example based on a really useful comment received today from @weston here on SO.

Old question but anyway !

Same thing happen to me this morning, everything was working fine for weeks before...... yes guess what ... I change my windows PC user account password yesterday night !!!!! (how stupid was I !!!)

So easy fix : IIS -> authentication -> Anonymous authentication -> edit and set the user and new PASSWORD !!!!!

Although many answers are given, I couldn't find one I am happy with. I figured out my own solution which makes property work for the dynamic case. The source to answer the original question:

#!/usr/local/bin/python3

INITS = { 'ab': 100, 'cd': 200 }

class DP(dict):
  def __init__(self):
    super().__init__()
    for k,v in INITS.items():
        self[k] = v 

def _dict_set(dp, key, value):
  dp[key] = value

for item in INITS.keys():
  setattr(
    DP,
    item,
    lambda key: property(
      lambda self: self[key], lambda self, value: _dict_set(self, key, value)
    )(item)
  )

a = DP()
print(a)  # {'ab': 100, 'cd': 200}
a.ab = 'ab100'
a.cd = False
print(a.ab, a.cd) # ab100 False

use

require_once(__DIR__.'/_path/_of/_filename.php');

This will also help in importing files in from different folders. Try extends method to inherit the classes in that file and reuse the functions

Try this:

X (\(Y\))? Z

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

$arr[$key]

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

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

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

would give you

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

You can install any application/packages with brew on mac. If you want to know the exact command just search your package on https://brewinstall.org and you will get the set of commands needed to install that package.

First open terminal and install brew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null

Now Install jq

brew install jq

You do it by stacking case labels:

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7: 
    case 12:
    ...
    break;
    ...
}

One can try Java Operator Overloading. It has its own limitations, but it worth trying if you really want to use operator overloading.

Assuming you’ve literally got two date objects, you can subtract one from the other and query the resulting timedelta object for the number of days:

>>> from datetime import date
>>> a = date(2011,11,24)
>>> b = date(2011,11,17)
>>> a-b
datetime.timedelta(7)
>>> (a-b).days
7

And it works with datetimes too — I think it rounds down to the nearest day:

>>> from datetime import datetime
>>> a = datetime(2011,11,24,0,0,0)
>>> b = datetime(2011,11,17,23,59,59)
>>> a-b
datetime.timedelta(6, 1)
>>> (a-b).days
6

I had the same problem, and it was caused by line for insecured registry in: /etc/default/docker

You don't need a function for it - simply use the bracket notation:

var side = columns['right'];

This is equal to dot notation, var side = columns.right;, except the fact that right could also come from a variable, function return value, etc., when using bracket notation.

If you NEED a function for it, here it is:

function read_prop(obj, prop) {
    return obj[prop];
}

To answer some of the comments below that aren't directly related to the original question, nested objects can be referenced through multiple brackets. If you have a nested object like so:

var foo = { a: 1, b: 2, c: {x: 999, y:998, z: 997}};

you can access property x of c as follows:

var cx = foo['c']['x']

If a property is undefined, an attempt to reference it will return undefined (not null or false):

foo['c']['q'] === null
// returns false

foo['c']['q'] === false
// returns false

foo['c']['q'] === undefined
// returns true

Just an FYI, you can optionally do it from the XML.

In the AndroidManifest.xml, you can set it with

android:label="My Activity Title"

Or

android:label="@string/my_activity_label"

Example:

    <activity
        android:name=".Splash"
        android:label="@string/splash_activity_title" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

If you don't care about the number of occurrences, I would approach it like this. Using hash sets will give you better performance than simple iteration.

var set1 = new HashSet<MyType>(list1);
var set2 = new HashSet<MyType>(list2);
return set1.SetEquals(set2);

This will require that you have overridden .GetHashCode() and implemented IEquatable<MyType> on MyType.

Add a jQuery function,

(function($){
    $.fn.regex = function(pattern, fn, fn_a){
        var fn = fn || $.fn.text;
        return this.filter(function() {
            return pattern.test(fn.apply($(this), fn_a));
        });
    };
})(jQuery);

Then,

$('span').regex(/Sent/)

will select all span elements with text matches /Sent/.

$('span').regex(/tooltip.year/, $.fn.attr, ['class'])

will select all span elements with their classes match /tooltip.year/.

My question was closed, I have no idea why . The accepted answer here is not the same as what I need.

This gives me the correct integer value for an IP..

public double IPAddressToNumber(string IPaddress)
{
    int i;
    string [] arrDec;
    double num = 0;
    if (IPaddress == "")
    {
        return 0;
    }
    else
    {
        arrDec = IPaddress.Split('.');
        for(i = arrDec.Length - 1; i >= 0 ; i = i -1)
            {
                num += ((int.Parse(arrDec[i])%256) * Math.Pow(256 ,(3 - i )));
            }
        return num;
    }
}

The foreign keys in your schema (on Account_Name and Account_Type) do not require any special treatment or syntax. Just declare two separate foreign keys on the Customer table. They certainly don't constitute a composite key in any meaningful sense of the word.

There are numerous other problems with this schema, but I'll just point out that it isn't generally a good idea to build a primary key out of multiple unique columns, or columns in which one is functionally dependent on another. It appears that at least one of these cases applies to the ID and Name columns in the Customer table. This allows you to create two rows with the same ID (different name), which I'm guessing you don't want to allow.

Try doubling up the single quotes (many databases expect it that way), so it would be :

INSERT INTO table_name (field1, field2) VALUES (123, 'Hello there''s');

Relevant quote from the documentation:

A string constant is formed by enclosing the string in single quotes ('). A single quote within the string can be encoded by putting two single quotes in a row - as in Pascal. C-style escapes using the backslash character are not supported because they are not standard SQL. BLOB literals are string literals containing hexadecimal data and preceded by a single "x" or "X" character. ... A literal value can also be the token "NULL".

CREATE TABLE NEW_TABLENAME LIKE OLD_TABLENAME;

Works for DB2 V 9.7

Let me expand a bit on a VonC's very comprehensive answer:

First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.

Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".

Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.

You can try using dictionary as:-

NSDictionary *infoDictionary = [[NSBundle mainBundle]infoDictionary];

NSString *buildVersion = infoDictionary[(NSString*)kCFBundleVersionKey];
NSString *bundleName = infoDictionary[(NSString *)kCFBundleNameKey]

You could use find to solve your problem

https://lodash.com/docs/#find

const data = [{"a": 1}, {"b": 2}]
const item = {"b": 2}


find(data, item)
// > true

Yes, although Internet Explorer 9 will compile your Javascript on a separate thread in preparation for execution on the main thread. This doesn't change anything for you as a programmer, though.

If you have a List of objects, you can serialize them to JSON as follow:

List<MyObjectClass> listOfObjects = new List<MyObjectClass>();

And then use addParameter:

requestREST.AddParameter("myAssocKey", JsonConvert.SerializeObject(listOfObjects));

And you wil need to set the request format to JSON:

requestREST.RequestFormat = DataFormat.Json;

I had similar issue, I imported a color theme and didn't like it. I never thought reverting will be so much trouble. I installed a color theme plugin "Eclipse Color Theme 0.14.0."

I went to Windows-->preferences-->General-->Appearance-->Color Theme. I selected the Default option. It reverted to default.

Hope this helps!

Disabled controls cannot be successful, and a successful control is "valid" for submission. This is the reason why disabled controls don't submit with the form.

Toolbar customization can done by following ways

write button and textViews code inside toolbar as shown below

<android.support.v7.widget.Toolbar
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <Button
      android:layout_width="wrap_content"
        android:layout_height="@dimen/btn_height_small"
        android:text="Departure"
        android:layout_gravity="right"
        />
</android.support.v7.widget.Toolbar>

Other way is to use item menu as shown below

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

You can try this:

$(".myclass").mouseover(function() {
    $(this).find(" > div").css("background-color","red");
}).mouseout(function() {
    $(this).find(" > div").css("background-color","transparent");
});

You just need a binary (with debugging symbols included) that is identical to the one that generated the core dump file. Then you can run gdb path/to/the/binary path/to/the/core/dump/file to debug it.

When it starts up, you can use bt (for backtrace) to get a stack trace from the time of the crash. In the backtrace, each function invocation is given a number. You can use frame number (replacing number with the corresponding number in the stack trace) to select a particular stack frame.

You can then use list to see code around that function, and info locals to see the local variables. You can also use print name_of_variable (replacing "name_of_variable" with a variable name) to see its value.

Typing help within GDB will give you a prompt that will let you see additional commands.

If your request is sent by HTTPS you will have an extra server variable named 'HTTPS'

if (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off') { //HTTPS } 

In your module build.gradle file make sure you have the correct plugin set. it should be

apply plugin: 'android'

You call both event listeners using .on() then use a if inside the function:

$(function(){
  $('#searchButton').on('keypress click', function(e){
    var search = $('#usersSearch').val();
    if (e.which === 13 || e.type === 'click') {
      $.post('../searchusers.php', {search: search}, function (response) {
        $('#userSearchResultsTable').html(response);
      });
    }
  });
});

I got this same error when working on a project to parse recent calendar events from Google Calendar.

Using the standard install with pip did not work for me, here is what I did to get the packages I needed.

Go directly to the source, here is a link for the google-api-python-client, but if you need a different language it should not be too different.

https://github.com/google/google-api-python-client

Click on the green "Clone or Download" button near the top left and save it as a zip file. Move the zip to your project folder and extract it there. Then cut all the files from the folder it creates back into the root of your project folder.

Yes, this does clutter your work space, but many compilers have ways to hide files.

After doing this the standard

from googleapiclient import discovery

works great.

Hope this helps.

Try this:

$("#message span").text("hello world!");

See it in your code!

function Errormessage(txt) {
    var m = $("#message");

    // set text before displaying message
    m.children("span").text(txt);

    // bind close listener
    m.children("a.close-notify").click(function(){
      m.fadeOut("slow");
    });

    // display message
    m.fadeIn("slow");
}

how about this solution? I didn't see anything like this in my search. I am trying to avoid division and make solution simpler.

   struct timeval cur_time1, cur_time2, tdiff;

   gettimeofday(&cur_time1,NULL);
   sleep(1);
   gettimeofday(&cur_time2,NULL);

   tdiff.tv_sec = cur_time2.tv_sec - cur_time1.tv_sec;
   tdiff.tv_usec = cur_time2.tv_usec + (1000000 - cur_time1.tv_usec);

   while(tdiff.tv_usec > 1000000)
   {
      tdiff.tv_sec++;
      tdiff.tv_usec -= 1000000;
      printf("updated tdiff tv_sec:%ld tv_usec:%ld\n",tdiff.tv_sec, tdiff.tv_usec);
   }

   printf("end tdiff tv_sec:%ld tv_usec:%ld\n",tdiff.tv_sec, tdiff.tv_usec);

Gradle 3.0 introduced next changes:

• compile -> api

  api keyword is the same as deprecated compile which expose this dependency for all levels

• compile -> implementation

  Is preferable way because has some advantages. implementation expose dependency only for one level up at build time (the dependency is available at runtime). As a result you have a faster build(no need to recompile consumers which are higher then 1 level up)

• provided -> compileOnly

  This dependency is available only in compile time(the dependency is not available at runtime). This dependency can not be transitive and be .aar. It can be used with compile time annotation processor and allows you to reduce a final output file

• compile -> annotationProcessor

  Very similar to compileOnly but also guarantees that transitive dependency are not visible for consumer

• apk -> runtimeOnly

  Dependency is not available in compile time but available at runtime.

I recently ran into the same problem having the TCPDF work with my CSS. Take a look at the code below. It worked for me after I changed the standard CSS to a format PHP would understand

Code Sample Below

$table = '<table width="100%" cellspacing="0" cellpadding="55%">
          <tr valign="bottom">
                <td class="header1" rowspan="2" align="center" valign="middle"
                      width="6%">Category</td>
                <td class="header1" rowspan="2" align="center" valign="middle"
                      width="26%">Project Description</td>
          </tr></table>';

You can also use Object.assign from ECMAScript 2015. It also allows you to add nested attributes at once. E.g.:

const myObject = {};

Object.assign(myObject, {
    firstNewAttribute: {
        nestedAttribute: 'woohoo!'
    }
});

Ps: This will not override the existing object with the assigned attributes. Instead they'll be added. However if you assign a value to an existing attribute then it would be overridden.

Yes there is. It is wrong. It won't work because it is wrong. Most browsers will only see one form.

http://www.w3.org/MarkUp/html3/forms.html

super is used to call the constructor, methods and properties of parent class.

In your operation in your initial question, you are performing the following operation:

item1.attr - item2.attr

So, assuming those are numbers (i.e. item1.attr = "1", item2.attr = "2") You still may use the "===" operator (or other strict evaluators) provided that you ensure type. The following should work:

return parseInt(item1.attr) - parseInt(item2.attr);

If they are alphaNumeric, then do use localCompare().

The other plus of using RecycleView is animation, it can be done in two lines of code

RecyclerView.ItemAnimator itemAnimator = new DefaultItemAnimator();
        recyclerView.setItemAnimator(itemAnimator);

But the widget is still raw, e.g you can't create header and footer.

Here's an easier way of doing this (source: here):

import matplotlib.pyplot as plt
from numpy.random import rand


fig, ax = plt.subplots()
for color in ['red', 'green', 'blue']:
    n = 750
    x, y = rand(2, n)
    scale = 200.0 * rand(n)
    ax.scatter(x, y, c=color, s=scale, label=color,
               alpha=0.3, edgecolors='none')

ax.legend()
ax.grid(True)

plt.show()

And you'll get this:

Take a look at here for legend properties

You can also change the position of the body/html to fixed:

body,
html {
  position: fixed;
}

Two ways to implement a Caesar Cipher:

Option 1: Change chars to ASCII numbers, then you can increase the value, then revert it back to the new character.

Option 2: Use a Map map each letter to a digit like this.

A - 0
B - 1
C - 2
etc...

With a map you don't have to re-calculate the shift every time. Then you can change to and from plaintext to encrypted by following map.

Try this:

find . -name "*.pdf" -type f -exec cp {} ./pdfsfolder \;

I would say the simplest solution would be to wrap the object and delegate the contains call to a collection of the wrapped class. This is similar to the comparator but doesn't force you to sort the resulting collection, you can simply use ArrayList.contains().

public class Widget {
        private String name;
        private String desc;

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getDesc() {
            return desc;
        }

        public void setDesc(String desc) {
            this.desc = desc;
        }
    }



    public abstract class EqualsHashcodeEnforcer<T> {

        protected T wrapped;

        public T getWrappedObject() {
            return wrapped;
        }

        @Override
        public boolean equals(Object obj) {
            return equalsDelegate(obj);

        protected boolean equalsDelegate(Object obj) {
            if (obj == null) {
                return false;
            }
            if (obj == getWrappedObject()) {
                return true;
            }
            if (obj.getClass() != getWrappedObject().getClass()) {
                return false;
            }
            Widget rhs = (Widget) obj;

            return new EqualsBuilder().append(getWrappedObject().getName(),
                    rhs.getName()).append(getWrappedObject().getDesc(),
                    rhs.getDesc()).isEquals();
        }

        @Override
        protected int hashCodeDelegate() {

            return new HashCodeBuilder(121, 991).append(
                    getWrappedObject().getName()).append(
                    getWrappedObject().getDesc()).toHashCode();
        }

    }

If you're talking about a web application, you should use the getRealPath from a ServletContext object.

Example:

public class MyServlet extends Servlet {
    public void doGet(HttpServletRequest req, HttpServletResponse resp) 
              throws ServletException, IOException{
         String webAppPath = getServletContext().getRealPath("/");
    }
}

Hope this helps.

In your example, the point of piping the output of find to xargs is that the standard behavior of find's -exec option is to execute the command once for each found file. If you're using find, and you want its standard behavior, then the answer is simple - don't use xargs to begin with.

This helped for me:

$("#input").keyup(function(event) {
        //use keyup instead keypress because:
        //- keypress will not work on backspace and delete
        //- keypress is called before the character is added to the textfield (at least in google chrome) 
        var searchText = $.trim($("#input").val());

        var c= String.fromCharCode(event.keyCode);
        var isWordCharacter = c.match(/\w/);
        var isBackspaceOrDelete = (event.keyCode == 8 || event.keyCode == 46);

        // trigger only on word characters, backspace or delete and an entry size of at least 3 characters
        if((isWordCharacter || isBackspaceOrDelete) && searchText.length > 2)
        { ...

Basically, no. That is an http header, so it is reasonable to cast to HttpWebRequest and set the .Referer (as you indicate in the question):

HttpWebRequest req = ...
req.Referer = "your url";

pure python code:

from math import sqrt

def stddev(lst):
    mean = float(sum(lst)) / len(lst)
    return sqrt(float(reduce(lambda x, y: x + y, map(lambda x: (x - mean) ** 2, lst))) / len(lst))

Simple answer is to use overflow: hidden and min-height: x(any) px which will auto-adjust the size of div.

The height: auto won't work.

All of these answers appear to be incomplete and/or kludges. Looking at the RestTemplate interface, it sure looks like it is intended to have a ClientHttpRequestFactory injected into it, and then that requestFactory will be used to create the request, including any customizations of headers, body, and request params.

You either need a universal ClientHttpRequestFactory to inject into a single shared RestTemplate or else you need to get a new template instance via new RestTemplate(myHttpRequestFactory).

Unfortunately, it looks somewhat non-trivial to create such a factory, even when you just want to set a single Authorization header, which is pretty frustrating considering what a common requirement that likely is, but at least it allows easy use if, for example, your Authorization header can be created from data contained in a Spring-Security Authorization object, then you can create a factory that sets the outgoing AuthorizationHeader on every request by doing SecurityContextHolder.getContext().getAuthorization() and then populating the header, with null checks as appropriate. Now all outbound rest calls made with that RestTemplate will have the correct Authorization header.

Without more emphasis placed on the HttpClientFactory mechanism, providing simple-to-overload base classes for common cases like adding a single header to requests, most of the nice convenience methods of RestTemplate end up being a waste of time, since they can only rarely be used.

I'd like to see something simple like this made available

@Configuration
public class MyConfig {
  @Bean
  public RestTemplate getRestTemplate() {
    return new RestTemplate(new AbstractHeaderRewritingHttpClientFactory() {
        @Override
        public HttpHeaders modifyHeaders(HttpHeaders headers) {
          headers.addHeader("Authorization", computeAuthString());
          return headers;
        }
        public String computeAuthString() {
          // do something better than this, but you get the idea
          return SecurityContextHolder.getContext().getAuthorization().getCredential();
        }
    });
  }
}

At the moment, the interface of the available ClientHttpRequestFactory's are harder to interact with than that. Even better would be an abstract wrapper for existing factory implementations which makes them look like a simpler object like AbstractHeaderRewritingRequestFactory for the purposes of replacing just that one piece of functionality. Right now, they are very general purpose such that even writing those wrappers is a complex piece of research.

If you are creating a new table, you can use the inline shortcut:

  def change
    create_table :posts do |t|
      t.string :title, null: false, index: { unique: true }
      t.timestamps
    end
  end

Spring is moving away from XML files and uses annotations heavily. The following example is a simple standalone Spring application which uses annotation instead of XML files.

package com.zetcode.bean;

import org.springframework.stereotype.Component;

@Component
public class Message {

   private String message = "Hello there!";

   public void setMessage(String message){

      this.message  = message;
   }

   public String getMessage(){

      return message;
   }
}

This is a simple bean. It is decorated with the @Component annotation for auto-detection by Spring container.

package com.zetcode.main;

import com.zetcode.bean.Message;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.ApplicationContext;
import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;

@ComponentScan(basePackages = "com.zetcode")
public class Application {

    public static void main(String[] args) {

        ApplicationContext context
                = new AnnotationConfigApplicationContext(Application.class);

        Application p = context.getBean(Application.class);
        p.start();
    }

    @Autowired
    private Message message;
    private void start() {
        System.out.println("Message: " + message.getMessage());
    }
}

This is the main Application class. The @ComponentScan annotation searches for components. The @Autowired annotation injects the bean into the message variable. The AnnotationConfigApplicationContext is used to create the Spring application context.

My Standalone Spring tutorial shows how to create a standalone Spring application with both XML and annotations.

I would place this as a comment to Triptych, but I can't comment yet due to lack of rating:

Using the enumerator method to match on sub-indices in a list of tuples. e.g.

li = [(1,2,3,4), (11,22,33,44), (111,222,333,444), ('a','b','c','d'),
        ('aa','bb','cc','dd'), ('aaa','bbb','ccc','ddd')]

# want pos of item having [22,44] in positions 1 and 3:

def getIndexOfTupleWithIndices(li, indices, vals):

    # if index is a tuple of subindices to match against:
    for pos,k in enumerate(li):
        match = True
        for i in indices:
            if k[i] != vals[i]:
                match = False
                break;
        if (match):
            return pos

    # Matches behavior of list.index
    raise ValueError("list.index(x): x not in list")

idx = [1,3]
vals = [22,44]
print getIndexOfTupleWithIndices(li,idx,vals)    # = 1
idx = [0,1]
vals = ['a','b']
print getIndexOfTupleWithIndices(li,idx,vals)    # = 3
idx = [2,1]
vals = ['cc','bb']
print getIndexOfTupleWithIndices(li,idx,vals)    # = 4

For a simple copy-tasks I can recommend copy-rename-maven-plugin. It's straight forward and simple to use:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>com.coderplus.maven.plugins</groupId>
        <artifactId>copy-rename-maven-plugin</artifactId>
        <version>1.0</version>
        <executions>
          <execution>
            <id>copy-file</id>
            <phase>generate-sources</phase>
            <goals>
              <goal>copy</goal>
            </goals>
            <configuration>
              <sourceFile>src/someDirectory/test.environment.properties</sourceFile>
              <destinationFile>target/someDir/environment.properties</destinationFile>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

If you would like to copy more than one file, replace the <sourceFile>...</destinationFile> part with

<fileSets>
  <fileSet>
    <sourceFile>src/someDirectory/test.environment.properties</sourceFile>
    <destinationFile>target/someDir/environment.properties</destinationFile>
  </fileSet>
  <fileSet>
    <sourceFile>src/someDirectory/test.logback.xml</sourceFile>
    <destinationFile>target/someDir/logback.xml</destinationFile>
  </fileSet>                
</fileSets>

Furthermore you can specify multiple executions in multiple phases if needed, the second goal is "rename", which simply does what it says while the rest of the configuration stays the same. For more usage examples refer to the Usage-Page.

Note: This plugin can only copy files, not directories. (Thanks to @james.garriss for finding this limitation.)

I have posted a very simple method to install OpenCV 2.4 for Python in Windows here : Install OpenCV in Windows for Python

It is just as simple as copy and paste. Hope it will be useful for future viewers.

1. Download Python, Numpy, OpenCV from their official sites.

2. Extract OpenCV (will be extracted to a folder opencv)

3. Copy ..\opencv\build\python\x86\2.7\cv2.pyd

4. Paste it in C:\Python27\Lib\site-packages

5. Open Python IDLE or terminal, and type

   >>> import cv2
   

If no errors shown, it is OK.

UPDATE (Thanks to dana for this info):

If you are using the VideoCapture feature, you must copy opencv_ffmpeg.dll into your path as well. See: https://stackoverflow.com/a/11703998/1134940

I was running into the problem where i had the json with some common keys. I wanted to group all the values having the same key. After some surfing I found hashmap package. Which is really helpful.

To group the element with the same key, I used multi(key:*, value:*, key2:*, value2:*, ...).

This package is somewhat similar to Java Hashmap collection, but not as powerful as Java Hashmap.

You can't free types that aren't dynamically allocated. Although arrays are syntactically similar (int* x = malloc(sizeof(int) * 4) can be used in the same way that int x[4] is), calling free(firstName) would likely cause an error for the latter.

For example, take this code:

int x;
free(&x);

free() is a function which takes in a pointer. &x is a pointer. This code may compile, even though it simply won't work.

If we pretend that all memory is allocated in the same way, x is "allocated" at the definition, "freed" at the second line, and then "freed" again after the end of the scope. You can't free the same resource twice; it'll give you an error.

This isn't even mentioning the fact that for certain reasons, you may be unable to free the memory at x without closing the program.

tl;dr: Just free the struct and you'll be fine. Don't call free on arrays; only call it on dynamically allocated memory.

Prasoon has already offered up a host of different (and good) ways to do this, none of which need repeating here. I'd like to suggest an alternative approach for speed however.

If you're going to be doing this quite a bit, you may want to consider "sub-classing" your vector so that a sum of elements is maintained separately (not actually sub-classing vector which is iffy due to the lack of a virtual destructor - I'm talking more of a class that contains the sum and a vector within it, has-a rather than is-a, and provides the vector-like methods).

For an empty vector, the sum is set to zero. On every insertion to the vector, add the element being inserted to the sum. On every deletion, subtract it. Basically, anything that can change the underlying vector is intercepted to ensure the sum is kept consistent.

That way, you have a very efficient O(1) method for "calculating" the sum at any point in time (just return the sum currently calculated). Insertion and deletion will take slightly longer as you adjust the total and you should take this performance hit into consideration.

Vectors where the sum is needed more often than the vector is changed are the ones likely to benefit from this scheme, since the cost of calculating the sum is amortised over all accesses. Obviously, if you only need the sum every hour and the vector is changing three thousand times a second, it won't be suitable.

Something like this would suffice:

class UberVector:
    private Vector<int> vec
    private int sum

    public UberVector():
        vec = new Vector<int>()
        sum = 0

    public getSum():
        return sum

    public add (int val):
        rc = vec.add (val)
        if rc == OK:
            sum = sum + val
        return rc

    public delindex (int idx):
        val = 0
        if idx >= 0 and idx < vec.size:
            val = vec[idx]
        rc =  vec.delindex (idx)
        if rc == OK:
            sum = sum - val
        return rc

Obviously, that's pseudo-code and you may want to have a little more functionality, but it shows the basic concept.

If your object could contain any key/value pairs, you could declare an interface called keyable like :

interface keyable {
    [key: string]: any  
}

then use it as follows :

let countryProviders: keyable[];

or

let countryProviders: Array<keyable>;

Short but sweet: for i in {1..10}; do history -d $(($HISTCMD-11)); done

WHERE something IS NULL

and

WHERE something IS NOT NULL

You can use a standard ASP.NET Panel and then set it's visible property in your code behind.

<asp:Panel ID="Panel1" runat="server" visible="false" />

To show panel in codebehind:

Panel1.Visible = true;

toString() only returns the exception name and the optional message. I would suggest calling

exception.printStackTrace()

to dump the message, or if you need the gory details:

 StackTraceElement[] trace = exception.getStackTrace()

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

use:

/^[ A-Za-z0-9_@./#&+-]*$/

You can also use the character class \w to replace A-Za-z0-9_

height : <percent> will only work if you have all parent nodes with specified percent height with a fixed height in pixels, ems, etc. on top level. That way, the height will cascade down to your element.

You can specify 100% to html and body elements as @Travis stated earlier to have the page height cascading down to your nodes.

I found it best to only update the calculation when a specific cell is changed. Here is an example VBA code to place in the "Worksheet" "Change" event:

Private Sub Worksheet_Change(ByVal Target As Range)
  If Not Intersect(Target, Range("F3")) Is Nothing Then
    Application.CalculateFull
  End If
End Sub

You can use the eq method or selector:

$('ul').find('li').eq(index).css({'background-color':'#343434'});

Try to use Aspose.cells library (not free, but trial is enough to read), it is quite good

Install-package Aspose.cells

There is sample code:

using Aspose.Cells;
using System;

namespace ExcelReader
{
    class Program
    {
        static void Main(string[] args)
        {
            // Replace path for your file
            readXLS(@"C:\MyExcelFile.xls"); // or "*.xlsx"
            Console.ReadKey();
        }

        public static void readXLS(string PathToMyExcel)
        {
            //Open your template file.
            Workbook wb = new Workbook(PathToMyExcel);

            //Get the first worksheet.
            Worksheet worksheet = wb.Worksheets[0];

            //Get cells
            Cells cells = worksheet.Cells;

            // Get row and column count
            int rowCount = cells.MaxDataRow;
            int columnCount = cells.MaxDataColumn;

            // Current cell value
            string strCell = "";

            Console.WriteLine(String.Format("rowCount={0}, columnCount={1}", rowCount, columnCount));

            for (int row = 0; row <= rowCount; row++) // Numeration starts from 0 to MaxDataRow
            {
                for (int column = 0; column <= columnCount; column++)  // Numeration starts from 0 to MaxDataColumn
                {
                    strCell = "";
                    strCell = Convert.ToString(cells[row, column].Value);
                    if (String.IsNullOrEmpty(strCell))
                    {
                        continue;
                    }
                    else
                    {
                        // Do your staff here
                        Console.WriteLine(strCell);
                    }
                }
            }
        }
    }
}

this code is tested with pdfminer for python 3 (pdfminer-20191125)

from pdfminer.layout import LAParams
from pdfminer.converter import PDFPageAggregator
from pdfminer.pdfinterp import PDFResourceManager
from pdfminer.pdfinterp import PDFPageInterpreter
from pdfminer.pdfpage import PDFPage
from pdfminer.layout import LTTextBoxHorizontal

def parsedocument(document):
    # convert all horizontal text into a lines list (one entry per line)
    # document is a file stream
    lines = []
    rsrcmgr = PDFResourceManager()
    laparams = LAParams()
    device = PDFPageAggregator(rsrcmgr, laparams=laparams)
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    for page in PDFPage.get_pages(document):
            interpreter.process_page(page)
            layout = device.get_result()
            for element in layout:
                if isinstance(element, LTTextBoxHorizontal):
                    lines.extend(element.get_text().splitlines())
    return lines

Although using '@' is more appropriate than using '=' for your particular scenario, sometimes I use '=' so that I don't have to remember to use attrs.$observe():

<su-label tooltip="field.su_documentation">{{field.su_name}}</su-label>

Directive:

myApp.directive('suLabel', function() {
    return {
        restrict: 'E',
        replace: true,
        transclude: true,
        scope: {
            title: '=tooltip'
        },
        template: '<label><a href="#" rel="tooltip" title="{{title}}" data-placement="right" ng-transclude></a></label>',
        link: function(scope, element, attrs) {
            if (scope.title) {
                element.addClass('tooltip-title');
            }
        },
    }
});

Fiddle.

With '=' we get two-way databinding, so care must be taken to ensure scope.title is not accidentally modified in the directive. The advantage is that during the linking phase, the local scope property (scope.title) is defined.

Skyhook (http://www.skyhookwireless.com/) has a location provider that is much faster than the standard one Google provides. It might be what you're looking for. I'm not affiliated with them.

simple solution

const handler1 = {
  construct(target, args) {
    let newDate = new target(...args);
    var tzDifference = newDate.getTimezoneOffset();
    return new target(newDate.getTime() + tzDifference * 60 * 1000);
  }
};

Date = new Proxy(Date, handler1);

Based on the doc

<div class="row">
    <div class="span4 collapse-group">
        <h2>Heading</h2>
        <p class="collapse">Donec id elit non mi porta gravida at eget metus. Fusce dapibus, tellus ac cursus commodo, tortor mauris condimentum nibh, ut fermentum massa justo sit amet risus. Etiam porta sem malesuada magna mollis euismod. Donec sed odio dui. </p>
        <p><a class="btn" href="#">View details &raquo;</a></p>
    </div>
</div>

$('.row .btn').on('click', function(e) {
    e.preventDefault();
    var $this = $(this);
    var $collapse = $this.closest('.collapse-group').find('.collapse');
    $collapse.collapse('toggle');
});

Working demo.

if only 1 row, you can use join

Select t1.Col1, t1.Col2, t1.Col3, t2.Col4, t2.Col5 from Table1 t1 join Table2 t2;

One other thing to note, if you updated a legacy app that had structs to use classes you might run into the following issue:

Old code has structs, code was cleaned up and these changed to classes. A virtual function or two was then added to the new updated class.

When virtual functions are in classes then internally the compiler will add extra pointer to the class data to point to the functions.

How this would break old legacy code is if in the old code somewhere the struct was cleared using memfill to clear it all to zeros, this would stomp the extra pointer data as well.

two ways:

x = [0] * 10
x = [0 for i in xrange(10)]

Edit: replaced range by xrange to avoid creating another list.

Also: as many others have noted including Pi and Ben James, this creates a list, not a Python array. While a list is in many cases sufficient and easy enough, for performance critical uses (e.g. when duplicated in thousands of objects) you could look into python arrays. Look up the array module, as explained in the other answers in this thread.

In build.gradle change minSdkVersion 13 to minSdkVersion 8 Thats all you need to do. I solved my problem by only doing this.

defaultConfig {
    applicationId "com.example.sabrim.sbrtest"
    minSdkVersion 8
    targetSdkVersion 20
    versionCode 1
    versionName "1.0"
}

I want to write a program that (...) creates the directory and a (...) file inside of it

because this is a very common question, here is the code to create multiple levels of directories and than call fopen. I'm using a gnu extension to print the error message with printf.

void rek_mkdir(char *path) {
    char *sep = strrchr(path, '/');
    if(sep != NULL) {
        *sep = 0;
        rek_mkdir(path);
        *sep = '/';
    }
    if(mkdir(path, 0777) && errno != EEXIST)
        printf("error while trying to create '%s'\n%m\n", path); 
}

FILE *fopen_mkdir(char *path, char *mode) {
    char *sep = strrchr(path, '/');
    if(sep) { 
        char *path0 = strdup(path);
        path0[ sep - path ] = 0;
        rek_mkdir(path0);
        free(path0);
    }
    return fopen(path,mode);
}

If anyone is struggling with angular version 4+ (mine was 4.3.6). This was the sample code which worked for me.

First add the required imports

import { Http, Headers, Response, URLSearchParams } from '@angular/http';

Then for the api function. It's a login sample which can be changed as per your needs.

login(username: string, password: string) {
    var headers = new Headers();
    headers.append('Content-Type', 'application/x-www-form-urlencoded');
    let urlSearchParams = new URLSearchParams();
    urlSearchParams.append('email', username);
    urlSearchParams.append('password', password);
    let body = urlSearchParams.toString()

    return this.http.post('http://localhost:3000/api/v1/login', body, {headers: headers})
        .map((response: Response) => {
            // login successful if user.status = success in the response
            let user = response.json();
            console.log(user.status)
            if (user && "success" == user.status) {
                // store user details and jwt token in local storage to keep user logged in between page refreshes
                localStorage.setItem('currentUser', JSON.stringify(user.data));
            }
        });
}

change the data type to another one which uses less memory works. For me, I change the data type to numpy.uint8:

data['label'] = data['label'].astype(np.uint8)

You have to provide the full path that you want to import.

import com.my.stuff.main.Main;
import com.my.stuff.second.*;

So, in your main class, you'd have:

package com.my.stuff.main

import com.my.stuff.second.Second;   // THIS IS THE IMPORTANT LINE FOR YOUR QUESTION

class Main {
   public static void main(String[] args) {
      Second second = new Second();
      second.x();  
   }
}

EDIT: adding example in response to Shawn D's comment

There is another alternative, as Shawn D points out, where you can specify the full package name of the object that you want to use. This is very useful in two locations. First, if you're using the class exactly once:

class Main {
    void function() {
        int x = my.package.heirarchy.Foo.aStaticMethod();

        another.package.heirarchy.Baz b = new another.package.heirarchy.Bax();
    }
}

Alternatively, this is useful when you want to differentiate between two classes with the same short name:

class Main {
    void function() {
        java.util.Date utilDate = ...;
        java.sql.Date sqlDate = ...;
    }
}

After looking at the SVG Recommendation I've come to the understanding that the baseline properties are meant to position text relative to other text, especially when mixing different fonts and or languages. If you want to postion text so that it's top is at y then you need use dy = "y + the height of your text".

check your routes.js file

example my routes.js

    const express = require('express')_x000D_
    const router = express.Router()_x000D_
    _x000D_
    const usersController = require('../app/controllers/usersController')_x000D_
    const autheticateuser = require('../app/middlewares/authentication')_x000D_
    _x000D_
    router.post('/users/login', autheticateuser, usersController.login)_x000D_
    router.post('/users/register', autheticateuser, usersController.register)_x000D_
      

check end of routes.js

module.exports = router

if not there add and module.exports = router run again

If your Error is : "TypeError: Route.post() or Route.get() requires middleware function but got a Object"

goto controller.js (i.e., usersController) and check all the function names you might misspelled , or you given in function routes file but missed in contollers

const User = require('../models/user')_x000D_
const express = require('express')_x000D_
const router = express.Router()_x000D_
_x000D_
_x000D_
_x000D_
module.exports.register = (req, res) => {_x000D_
    const data = req.body_x000D_
    const user = new User(data)_x000D_
    user.save()_x000D_
        .then((user) => {_x000D_
            res.send(user)_x000D_
        })_x000D_
        .catch((err) => {_x000D_
            res.json(err)_x000D_
        })_x000D_
}

in routes.js i given two routes but in controllers i missed to define route for

router.post('/users/login')

this will make error **

"TypeError: route.post() requires middleware function but got a Object"

**

best to use crypt for password storing in DB

example code :

$crypted_pass = crypt($password);

//$pass_from_login is the user entered password
//$crypted_pass is the encryption
if(crypt($pass_from_login,$crypted_pass)) == $crypted_pass)
{
   echo("hello user!")
}

documentation :

http://www.php.net/manual/en/function.crypt.php

yourEnumList.Select(s => (int)s).ToList()

PEP 8 defines that it is better to use the is operator when comparing singletons.

Dim celltxt As String
Range("C6").Select
Selection.End(xlToRight).Select
celltxt = Selection.Text
If InStr(1, celltext, "TOTAL") > 0 Then
Range("C7").Select 
Selection.End(xlToRight).Select
Selection.Value = "-"
End If

You declared "celltxt" and used "celltext" in the instr.

Further to Stephen Weinberg's answer, I have since implemented a handy tool called iojson, which helps to populate data to an existing object easily as well as encoding the existing object to a JSON string. A iojson middleware is also provided to work with other middlewares. More examples can be found at https://github.com/junhsieh/iojson

Example:

func main() {
    jsonStr := `{"Status":true,"ErrArr":[],"ObjArr":[{"Name":"My luxury car","ItemArr":[{"Name":"Bag"},{"Name":"Pen"}]}],"ObjMap":{}}`

    car := NewCar()

    i := iojson.NewIOJSON()

    if err := i.Decode(strings.NewReader(jsonStr)); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    }

    // populating data to a live car object.
    if v, err := i.GetObjFromArr(0, car); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    } else {
        fmt.Printf("car (original): %s\n", car.GetName())
        fmt.Printf("car (returned): %s\n", v.(*Car).GetName())

        for k, item := range car.ItemArr {
            fmt.Printf("ItemArr[%d] of car (original): %s\n", k, item.GetName())
        }

        for k, item := range v.(*Car).ItemArr {
            fmt.Printf("ItemArr[%d] of car (returned): %s\n", k, item.GetName())
        }
    }
}

Sample output:

car (original): My luxury car
car (returned): My luxury car
ItemArr[0] of car (original): Bag
ItemArr[1] of car (original): Pen
ItemArr[0] of car (returned): Bag
ItemArr[1] of car (returned): Pen

You can place your json to js file and save it to global variable. It is not asynchronous, but it can help.

Since you're not using JSON as the data type no your AJAX call, I would assume that you can't access the value because the PHP you gave will only ever be true or false. isset is a function to check if something exists and has a value, not to get access to the value.

Change your PHP to be:

$uid = (isset($_POST['userID'])) ? $_POST['userID'] : 0;

The above line will check to see if the post variable exists. If it does exist it will set $uid to equal the posted value. If it does not exist then it will set $uid equal to 0.

Later in your code you can check the value of $uid and react accordingly

if($uid==0) {
    echo 'User ID not found';
}

This will make your code more readable and also follow what I consider to be best practices for handling data in PHP.

To convert Blob to String in Java:

byte[] bytes = baos.toByteArray();//Convert into Byte array
String blobString = new String(bytes);//Convert Byte Array into String

^([A-Z][a-z]+)+$

This looks for sequences of an uppercase letter followed by one or more lowercase letters. Consecutive uppercase letters will not match, as only one is allowed at a time, and it must be followed by a lowercase one.

Make sure your id_rsa file doesn't have any extension like .txt or .rtf. Rich Text Format adds additional characters to your file and those gets added to byte array. Which eventually causes invalid private key error. Long story short, Copy the file, not content.

I'm going to take a stab in the dark and guess you're talking about Windows. In a nutshell, kernel mode has full access to hardware, but user mode doesn't. For instance, many if not most device drivers are written in kernel mode because they need to control finer details of their hardware.

See also this wikibook.

You can use prototype cells with a custom height, and then invoke cellForRowAtIndexPath: and return its frame.height.:.

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *cell = [self tableView:tableView
                    cellForRowAtIndexPath:indexPath];
    return cell.frame.size.height;
}

As for me, most elegant way is yield break

To add an element to an array you need to use the format:

array[index] = element;

Where array is the array you declared, index is the position where the element will be stored, and element is the item you want to store in the array.

In your code, you'd want to do something like this:

int[] num = new int[args.length];
for (int i = 0; i < args.length; i++) {
    int neki = Integer.parseInt(args[i]);
    num[i] = neki;
}

The add() method is available for Collections like List and Set. You could use it if you were using an ArrayList (see the documentation), for example:

List<Integer> num = new ArrayList<>();
for (String s : args) {
    int neki = Integer.parseInt(s);
    num.add(neki);
}

Wouldn't it be significantly more readable to do a positive match and reject those strings - rather than match the negative to find strings to accept?

Change the default block from "Code" to "Markdown" before running this code:

![<caption>](image_filename.png)

If image file is in another folder, you can do the following:

![<caption>](folder/image_filename.png)

This is in the feature backlog for Compose but it doesn't look like work has been started yet. Github issue.

The solution I have applied to this situation is to simply place an absolute loading image in the DOM, which will be covered by the iframe layer after the iframe is loaded.

The z-index of the iframe should be (loading's z-index + 1), or just higher.

For example:

.loading-image { position: absolute; z-index: 0; }
.iframe-element { position: relative; z-index: 1; }

Hope this helps if no javaScript solution did. I do think that CSS is best practice for these situations.

Best regards.

Option1:

List<String> list = Arrays.asList("hello");

Option2:

List<String> list = new ArrayList<String>(Arrays.asList("hello"));

In my opinion, Option1 is better because

1. we can reduce the number of ArrayList objects being created from 2 to 1. asList method creates and returns an ArrayList Object.
2. its performance is much better (but it returns a fixed-size list).

Please refer to the documentation here

Three of the suggested methods were tested for speed with 1000 RGBA PNG images (224 x 256 pixels) running with Python 3.5 on Ubuntu 16.04 LTS (Xeon E5 2670 with SSD).

Average run times

pil : 1.037 seconds

scipy: 1.040 seconds

sk : 2.120 seconds

PIL and SciPy gave identical numpy arrays (ranging from 0 to 255). SkImage gives arrays from 0 to 1. In addition the colors are converted slightly different, see the example from the CUB-200 dataset.

Code

1. Performance

   run_times = dict(sk=list(), pil=list(), scipy=list())
   for t in range(100):
       start_time = time.time()
       for i in range(1000):
           z = random.choice(filenames_png)
           img = skimage.color.rgb2gray(skimage.io.imread(z))
       run_times['sk'].append(time.time() - start_time)
   
   start_time = time.time()
   for i in range(1000):
       z = random.choice(filenames_png)
       img = np.array(Image.open(z).convert('L'))
   run_times['pil'].append(time.time() - start_time)
   
   start_time = time.time()
   for i in range(1000):
       z = random.choice(filenames_png)
       img = scipy.ndimage.imread(z, mode='L')
   run_times['scipy'].append(time.time() - start_time)
   
   for k, v in run_times.items():
   print('{:5}: {:0.3f} seconds'.format(k, sum(v) / len(v)))
   

2. Output

   z = 'Cardinal_0007_3025810472.jpg'
   img1 = skimage.color.rgb2gray(skimage.io.imread(z)) * 255
   IPython.display.display(PIL.Image.fromarray(img1).convert('RGB'))
   img2 = np.array(Image.open(z).convert('L'))
   IPython.display.display(PIL.Image.fromarray(img2))
   img3 = scipy.ndimage.imread(z, mode='L')
   IPython.display.display(PIL.Image.fromarray(img3))
   

3. Comparison

   img_diff = np.ndarray(shape=img1.shape, dtype='float32')
   img_diff.fill(128)
   img_diff += (img1 - img3)
   img_diff -= img_diff.min()
   img_diff *= (255/img_diff.max())
   IPython.display.display(PIL.Image.fromarray(img_diff).convert('RGB'))
   

4. Imports

   import skimage.color
   import skimage.io
   import random
   import time
   from PIL import Image
   import numpy as np
   import scipy.ndimage
   import IPython.display

   scipy.version
   0.19.1
   np.version

In C++11 you could also create an alias for convenience:

template<class T> using min_heap = priority_queue<T, std::vector<T>, std::greater<T>>;

And use it like this:

min_heap<int> my_heap;

Instead of selecting all the columns in count count(*) you can limit count for one column count(UserName).

You can limit the whole search to one row by using Limit 0,1

SELECT COUNT(UserName)
  FROM TableName
 WHERE UserName = 'User' AND
       Password = 'Pass'
 LIMIT 0, 1

1. Migrate your DB "simply make sure the tables and columns exist".
2. Recommended to delete all your data (this freezes MySQL Workbench on my MAC everytime due to "software out of memory..")

1. Open MySQL Workbench
2. click + to make MySQL connection
3. enter credentials and connect
4. go to database tab
5. click reverse engineer
6. follow the wizard Next > Next ….
7. DONE :)
8. now you can click the arrange tab then choose auto-layout (keep clicking it until you are satisfied with the result)

The default value of the argument must be a constant expression. It can't be a variable or a function call.

If you need this functionality however:

function foo($foo, $bar = false)
{
    if(!$bar)
    {
        $bar = $foo;
    }
}

Assuming $bar isn't expected to be a boolean of course.

One equivalent of lsof could be combined output from Sysinternals' handle and listdlls, i.e.:

c:\SysInternals>handle
[...]
------------------------------------------------------------------------------
gvim.exe pid: 5380 FOO\alois.mahdal
   10: File  (RW-)   C:\Windows
   1C: File  (RW-)   D:\some\locked\path\OpenFile.txt
[...]

c:\SysInternals>listdlls
[...]
------------------------------------------------------------------------------
Listdlls.exe pid: 6840
Command line: listdlls

  Base        Size      Version         Path
  0x00400000  0x29000   2.25.0000.0000  D:\opt\SysinternalsSuite\Listdlls.exe
  0x76ed0000  0x180000  6.01.7601.17725  C:\Windows\SysWOW64\ntdll.dll
[...]

c:\SysInternals>listdlls

Unfortunately, you have to "run as Administrator" to be able to use them.

Also listdlls and handle do not produce continuous table-like form so filtering filename would hide PID. findstr /c:pid: /c:<filename> should get you very close with both utilities, though

c:\SysinternalsSuite>handle | findstr /c:pid: /c:Driver.pm
System pid: 4 \<unable to open process>
smss.exe pid: 308 NT AUTHORITY\SYSTEM
avgrsa.exe pid: 384 NT AUTHORITY\SYSTEM
[...]
cmd.exe pid: 7140 FOO\alois.mahdal
conhost.exe pid: 1212 FOO\alois.mahdal
gvim.exe pid: 3408 FOO\alois.mahdal
  188: File  (RW-)   D:\some\locked\path\OpenFile.txt
taskmgr.exe pid: 6016 FOO\alois.mahdal
[...]

Here we can see that gvim.exe is the one having this file open.

Although PHP_INT_* constants exist for a very long time, the same MIN / MAX values could be found programmatically by left shifting until reaching the negative number:

$x = 1;
while ($x > 0 && $x <<= 1);
echo "MIN: ", $x;
echo PHP_EOL;
echo "MAX: ", ~$x;

Starting in Django 1.2 RC1, if you're using the Django admin date picker widge trick, the following has to be added to your template, or you'll see the calendar icon url being referenced through "/missing-admin-media-prefix/".

{% load adminmedia %} /* At the top of the template. */

/* In the head section of the template. */
<script type="text/javascript">
window.__admin_media_prefix__ = "{% filter escapejs %}{% admin_media_prefix %}{% endfilter %}";
</script>

Please consider the deasync module, personally I don't like the Promise way to make all functions async, and keyword async/await anythere. And I think the official node.js should consider to expose the event loop API, this will solve the callback hell simply. Node.js is a framework not a language.

var node = require("deasync");
node.loop = node.runLoopOnce;

var done = 0;
// async call here
db.query("select * from ticket", (error, results, fields)=>{
    done = 1;
});

while (!done)
    node.loop();

// Now, here you go

You must set Access-Control-Allow-Credentials: true, if you want to use "cookie" via "Credentials"

app.all('*', function(req, res, next) {
  res.header('Access-Control-Allow-Origin', '*');
  res.header('Access-Control-Allow-Credentials', true);
  res.header('Access-Control-Allow-Methods', 'PUT, GET, POST, DELETE, OPTIONS');
  res.header('Access-Control-Allow-Headers', 'Content-Type');
  next();
});

Why would you want to remove the linking, it makes it very user friendly to have th eoption.

If you simply want to remove the auto editing, but keep the link working just add this into your CSS...

a[href^=tel] {
 color: inherit;
 text-decoration:inherit;
}

Although answer is provided I found simpler solution:

Date:

01/20/2017

By doing replace

CurrentDate = replace(date, "/", "-")

It will output:

01-20-2017

To check dataset is empty or not You have to check null and tables count.

DataSet ds = new DataSet();
SqlDataAdapter da = new SqlDataAdapter(sqlString, sqlConn);
da.Fill(ds);
if(ds != null && ds.Tables.Count > 0)
{
 // your code
}

The HTML parser simply doesn't interpret the inlined javascript like this.

You may do this :

<td><input type="checkbox" id="repriseCheckBox" name="repriseCheckBox"/></td>

<script>document.getElementById("repriseCheckBox").disabled=checkStat == 1 ? true : false;</script>

Your group statement will group by group ID. For example, if you then write:

foreach (var group in groupedCustomerList)
{
    Console.WriteLine("Group {0}", group.Key);
    foreach (var user in group)
    {
        Console.WriteLine("  {0}", user.UserName);
    }
}

that should work fine. Each group has a key, but also contains an IGrouping<TKey, TElement> which is a collection that allows you to iterate over the members of the group. As Lee mentions, you can convert each group to a list if you really want to, but if you're just going to iterate over them as per the code above, there's no real benefit in doing so.

Easiest way is actually a script.

Run this on production:

USE MASTER;

BACKUP DATABASE [MyDatabase]
TO DISK = 'C:\temp\MyDatabase1.bak' -- some writeable folder. 
WITH COPY_ONLY

This one command makes a complete backup copy of the database onto a single file, without interfering with production availability or backup schedule, etc.

To restore, just run this on your dev or test SQL Server:

USE MASTER;

RESTORE DATABASE [MyDatabase]
FROM DISK = 'C:\temp\MyDatabase1.bak'
WITH
MOVE 'MyDatabase'   TO 'C:\Sql\MyDatabase.mdf', -- or wherever these live on target
MOVE 'MyDatabase_log'   TO 'C:\Sql\MyDatabase_log.ldf',
REPLACE, RECOVERY

Then save these scripts on each server. One-click convenience.

Edit:
if you get an error when restoring that the logical names don't match, you can get them like this:

RESTORE FILELISTONLY
FROM disk = 'C:\temp\MyDatabaseName1.bak'

If you use SQL Server logins (not windows authentication) you can run this after restoring each time (on the dev/test machine):

use MyDatabaseName;
sp_change_users_login 'Auto_Fix', 'userloginname', null, 'userpassword';

For me maven was downloading the dependency but was unable to add it to the classpath. I saw my .classpath of the project,it didnt have any maven-related entry. When I added

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER"/>

the issue got resolved for me.

To avoid the boilerplate for every different type of error, I combined the wisdom of some of the solutions into a createErrorType function:

function createErrorType(name, init) {
  function E(message) {
    if (!Error.captureStackTrace)
      this.stack = (new Error()).stack;
    else
      Error.captureStackTrace(this, this.constructor);
    this.message = message;
    init && init.apply(this, arguments);
  }
  E.prototype = new Error();
  E.prototype.name = name;
  E.prototype.constructor = E;
  return E;
}

Then you can define new error types easily as follows:

var NameError = createErrorType('NameError', function (name, invalidChar) {
  this.message = 'The name ' + name + ' may not contain ' + invalidChar;
});

var UnboundError = createErrorType('UnboundError', function (variableName) {
  this.message = 'Variable ' + variableName + ' is not bound';
});

Add below code to following files.

app.component.ts

<input type="text" [(ngModel)]="fname" >
{{fname}}
export class appcomponent {
fname:any;
}

app.module.ts

import {FormsModule} from '@angular/forms';
@NgModule({
imports: [ BrowserModule,FormsModule ],
declarations: [ AppComponent],
bootstrap:    [ AppComponent ]
})

For System.Timers.Timer, on separate thread, if SynchronizingObject is not set.

    static System.Timers.Timer DummyTimer = null;

    static void Main(string[] args)
    {
        try
        {

            Console.WriteLine("Main Thread Id: " + System.Threading.Thread.CurrentThread.ManagedThreadId);

            DummyTimer = new System.Timers.Timer(1000 * 5); // 5 sec interval
            DummyTimer.Enabled = true;
            DummyTimer.Elapsed += new System.Timers.ElapsedEventHandler(OnDummyTimerFired);
            DummyTimer.AutoReset = true;

            DummyTimer.Start();

            Console.WriteLine("Hit any key to exit");
            Console.ReadLine();
        }
        catch (Exception Ex)
        {
            Console.WriteLine(Ex.Message);
        }

        return;
    }

    static void OnDummyTimerFired(object Sender, System.Timers.ElapsedEventArgs e)
    {
        Console.WriteLine(System.Threading.Thread.CurrentThread.ManagedThreadId);
        return;
    }

Output you'd see if DummyTimer fired on 5 seconds interval:

Main Thread Id: 9
   12
   12
   12
   12
   12
   ... 

So, as seen, OnDummyTimerFired is executed on Workers thread.

No, further complication - If you reduce interval to say 10 ms,

Main Thread Id: 9
   11
   13
   12
   22
   17
   ... 

This is because if prev execution of OnDummyTimerFired isn't done when next tick is fired, then .NET would create a new thread to do this job.

Complicating things further, "The System.Timers.Timer class provides an easy way to deal with this dilemma—it exposes a public SynchronizingObject property. Setting this property to an instance of a Windows Form (or a control on a Windows Form) will ensure that the code in your Elapsed event handler runs on the same thread on which the SynchronizingObject was instantiated."

I had similar problem. In my device I have two accounts and the app was remained installed in another account. I have deleted app from both of the accounts and it was done.

A very common usecase of calc is take 100% width and adding some margin around the element.

One can do so with:

@someMarginVariable = 15px;

margin: @someMarginVariable;
width: calc(~"100% - "@someMarginVariable*2);
width: -moz-calc(~"100% - "@someMarginVariable*2);
width: -webkit-calc(~"100% - "@someMarginVariable*2);

have you tried:

.image_block{
text-align: center;
vertical-align: bottom;
}

PFX files are PKCS#12 Personal Information Exchange Syntax Standard bundles. They can include arbitrary number of private keys with accompanying X.509 certificates and a certificate authority chain (set certificates).

If you want to extract client certificates, you can use OpenSSL's PKCS12 tool.

openssl pkcs12 -in input.pfx -out mycerts.crt -nokeys -clcerts

The command above will output certificate(s) in PEM format. The ".crt" file extension is handled by both macOS and Window.

You mention ".cer" extension in the question which is conventionally used for the DER encoded files. A binary encoding. Try the ".crt" file first and if it's not accepted, easy to convert from PEM to DER:

openssl x509 -inform pem -in mycerts.crt -outform der -out mycerts.cer

I wrote a plugin sometime back for attrchange listener which basically adds a listener function on attribute change. Even though I say it as a plugin, actually it is a simple function written as a jQuery plugin.. so if you want.. strip off the plugin specfic code and use the core functions.

Note: This code doesn't use polling

check out this simple demo http://jsfiddle.net/aD49d/

$(function () {
    var prevHeight = $('#test').height();
    $('#test').attrchange({
        callback: function (e) {
            var curHeight = $(this).height();            
            if (prevHeight !== curHeight) {
               $('#logger').text('height changed from ' + prevHeight + ' to ' + curHeight);

                prevHeight = curHeight;
            }            
        }
    }).resizable();
});

Since I didn't like some of the code in the other answers, here's my simple solution. This solution is meant to be usable in an Activity or Service to track the location. It makes sure that it never returns data that's too stale unless you explicitly request stale data. It can be run in either a callback mode to get updates as we receive them, or in poll mode to poll for the most recent info.

Generic LocationTracker interface. Allows us to have multiple types of location trackers and plug the appropriate one in easily:

package com.gabesechan.android.reusable.location;

import android.location.Location;

public interface LocationTracker {
    public interface LocationUpdateListener{
        public void onUpdate(Location oldLoc, long oldTime, Location newLoc, long newTime);
    }

    public void start();
    public void start(LocationUpdateListener update);

    public void stop();

    public boolean hasLocation();

    public boolean hasPossiblyStaleLocation();

    public Location getLocation();

    public Location getPossiblyStaleLocation();

}

ProviderLocationTracker- this class will track the location for either GPS or NETWORK.

package com.gabesechan.android.reusable.location;

import android.content.Context;
import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;

public class ProviderLocationTracker implements LocationListener, LocationTracker {

The is the FallbackLocationTracker, which will track by both GPS and NETWORK, and use whatever location is more accurate.

package com.gabesechan.android.reusable.location;

import android.content.Context;
import android.location.Location;
import android.location.LocationManager;

public class FallbackLocationTracker  implements LocationTracker, LocationTracker.LocationUpdateListener {

        if(lastLoc == null){
            update = true;
        }
        else if(lastLoc != null && lastLoc.getProvider().equals(newLoc.getProvider())){

            lastTime = newTime;

    }
}

Since both implement the LocationTracker interface, you can easily change your mind about which one to use. To run the class in poll mode, just call start(). To run it in update mode, call start(Listener).

Also take a look at my blog post on the code

ls has the option -m to delimit the output with ", " a comma and a space.

ls -m | tr -d ' ' | tr ',' ';'

piping this result to tr to remove either the space or the comma will allow you to pipe the result again to tr to replace the delimiter.

in my example i replace the delimiter , with the delimiter ;

replace ; with whatever one character delimiter you prefer since tr only accounts for the first character in the strings you pass in as arguments.

You have to do bulk insert with format file:

   BULK INSERT Employee FROM 'path\tempFile.csv ' 
   WITH (FORMATFILE = 'path\tempFile.fmt');

where format file (tempFile.fmt) looks like this:

11.0
2
1 SQLCHAR 0 50 "\t"  2  Name   SQL_Latin1_General_CP1_CI_AS
2 SQLCHAR 0 50 "\r\n" 3  Address  SQL_Latin1_General_CP1_CI_AS

more details here - http://msdn.microsoft.com/en-us/library/ms179250.aspx

You need to add logic to assign random values to double[] array using randomFill method.

Change

 public static double[] list(){
    anArray = new double[10];   
    return anArray;
 }

To

 public static double[] list() {
    anArray = new double[10];
    for(int i=0;i<anArray.length;i++)
    {
        anArray[i] = randomFill();
    }
    return anArray;
}

Then you can call methods, including list() and print() in main method to generate random double values and print the double[] array in console.

 public static void main(String args[]) {

list();
print();
 }

One result is as follows:

-2.89783865E8 
1.605018025E9 
-1.55668528E9 
-1.589135498E9 
-6.33159518E8 
-1.038278095E9

You may actually go with ViewChild API...

• Check your forked plunker for complete code - ViewChild API

parent.ts

<button (click)="clicked()">click</button>

export class App {
  @ViewChild(Child) vc:Child;
  constructor() {
    this.name = 'Angular2'
  }

  func(e) {
    console.log(e)

  }
  clicked(){
   this.vc.getName();
  }
}

child.ts

export class Child implements OnInit{

  onInitialized = new EventEmitter<Child>();
  ...  
  ...
  getName()
  {
     console.log('called by vc')
     console.log(this.name);
  }
}

Its more likely that the path to file.js from the page is what is wrong. as long as when you view the page, and view-source you see the tag, its working, now its time to debug whether or not your path is too relative, maybe you need a / in front of it.

To disable close button you should add the following code to your Window class (the code was taken from here, edited and reformatted a bit):

protected override void OnSourceInitialized(EventArgs e)
{
    base.OnSourceInitialized(e);

    HwndSource hwndSource = PresentationSource.FromVisual(this) as HwndSource;

    if (hwndSource != null)
    {
        hwndSource.AddHook(HwndSourceHook);
    }

}

private bool allowClosing = false;

[DllImport("user32.dll")]
private static extern IntPtr GetSystemMenu(IntPtr hWnd, bool bRevert);
[DllImport("user32.dll")]
private static extern bool EnableMenuItem(IntPtr hMenu, uint uIDEnableItem, uint uEnable);

private const uint MF_BYCOMMAND = 0x00000000;
private const uint MF_GRAYED = 0x00000001;

private const uint SC_CLOSE = 0xF060;

private const int WM_SHOWWINDOW = 0x00000018;
private const int WM_CLOSE = 0x10;

private IntPtr HwndSourceHook(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{
    switch (msg)
    {
        case WM_SHOWWINDOW:
            {
                IntPtr hMenu = GetSystemMenu(hwnd, false);
                if (hMenu != IntPtr.Zero)
                {
                    EnableMenuItem(hMenu, SC_CLOSE, MF_BYCOMMAND | MF_GRAYED);
                }
            }
            break;
        case WM_CLOSE:
            if (!allowClosing)
            {
                handled = true;
            }
            break;
    }
    return IntPtr.Zero;
}

This code also disables close item in System menu and disallows closing the dialog using Alt+F4.

You will probably want to close the window programmatically. Just calling Close() will not work. Do something like this:

allowClosing = true;
Close();

In a word - speed. An index for up to a million rows fits in a 32-bit word, so it can be used efficiently on 32-bit processors. Function arguments that fit in a CPU register are extremely efficient, while ones that are larger require accessing memory on each function call, a far slower operation. Updating a spreadsheet can be an intensive operation involving many cell references, so speed is important. Besides, the Excel team expects that anyone dealing with more than a million rows will be using a database rather than a spreadsheet.

(new Double(d)).longValue() internally just does a cast, so there's no reason to create a Double object.

It turns out the compiler version I was using did not match the compiled version done with the coreset.o.

One was 32bit the other was 64bit. I'll leave this up in case anyone else runs into a similar problem.

I was running into the problem of the tooltip doing some funky stuff when the close button became clicked. To work around this I used a span instead of using a button. Also, when the close button was clicked I would have to click the tooltip twice after it closed in order to get it to open again. To work around this I simply used the .click() method, as seen below.

<span tabindex='0' class='tooltip-close close'>×</span>

$('#myTooltip').tooltip({
    html: true,
    title: "Hello From Tooltip",
    trigger: 'click'
});    

$("body").on("click", ".tooltip-close", function (e) {
    else {
        $('.tooltip').remove();
        $('#postal-premium-tooltip').click();
    }
});

Use the CSS display values of table and table-cell:

HTML

<html>
<body>

  <div class="valign bottom">
    <div>

      <div>my bottom aligned div 1</div>
      <div>my bottom aligned div 2</div>
      <div>my bottom aligned div 3</div>

    </div>
  </div>

</body>
</html>

CSS

html,body {
    width: 100%;
    height: 100%;
}
.valign {
    display: table;
    width: 100%;
    height: 100%;
}
.valign > div {
    display: table-cell;
    width: 100%;
    height: 100%;
}
.valign.bottom > div {
    vertical-align: bottom;
}

I've created a JSBin demo here: http://jsbin.com/INOnAkuF/2/edit

The demo also has an example how to vertically center align using the same technique.

In View

<select ng-model="boxmodel"><option ng-repeat="lst in list" value="{{lst.id}}">{{lst.name}}</option></select>

JS:

In side controller

 $scope.boxModel = 600;

public class Person{

    String s;
    Date d;
    ...

    public Person clone(){
        Person p = new Person();
        p.s = this.s.clone();
        p.d = this.d.clone();
        ...
        return p;
    }
}

In your executing code:

ArrayList<Person> clone = new ArrayList<Person>();
for(Person p : originalList)
    clone.add(p.clone());

I think this works for SQL 2000:

SELECT 
    CASE WHEN C.autoval IS NOT NULL THEN
        'Identity'
    ELSE
        'Not Identity'
    AND
FROM
    sysobjects O
INNER JOIN
    syscolumns C
ON
    O.id = C.id
WHERE
    O.NAME = @TableName
AND
    C.NAME = @ColumnName

Try specifying a DC in DomainB using the -Server property. Ex:

Get-ADUser -Server "dc01.DomainB.local" -Filter {EmailAddress -like "*Smith_Karla*"} -Properties EmailAddress

try this..

<tr ng-repeat='item in items'>
<td>{{item.Name}}</td>
<td>{{item.Price}}</td>
<td>{{item.Quantity}}</td>
</tr>

Use DATE_FORMAT from Date Conversions:

In your initializer:

DateTime::DATE_FORMATS[:my_date_format] = "%a %b %d %H:%M:%S %Z %Y"

In your view:

date = DateTime.parse("2011-05-19 10:30:14")
date.to_formatted_s(:my_date_format)
date.to_s(:my_date_format) 

Consider the following:

int n;
for(n = 0; n < 10; ++n) {
    break;
}
System.out.println(n);

break causes the loop to terminate and the value of n is 0.

int n;
for(n = 0; n < 10; ++n) {
    continue;
}
System.out.println(n);

continue causes the program counter to return to the first line of the loop (the condition is checked and the value of n is increment) and the final value of n is 10.

It should also be noted that break only terminates the execution of the loop it is within:

int m;
for(m = 0; m < 5; ++m)
{
    int n;
    for(n = 0; n < 5; ++n) {
        break;
    }
    System.out.println(n);
}
System.out.println(m);

Will output something to the effect of

0
0
0
0
0
5

I don't think adb pull handles wildcards for multiple files. I ran into the same problem and did this by moving the files to a folder and then pulling the folder.

I found a link doing the same thing. Try following these steps.

How to copy selected files from Android with adb pull

I agree with bizl

[XmlInclude(typeof(ParentOfTheItem))]
[Serializable]
public abstract class WarningsType{ }

also if you need to apply this included class to an object item you can do like that

[System.Xml.Serialization.XmlElementAttribute("Warnings", typeof(WarningsType))]
public object[] Items
{
    get
    {
        return this.itemsField;
    }
    set
    {
        this.itemsField = value;
    }
}

In your file.php of request ajax, can set value header.

<?php header('Access-Control-Allow-Origin: *'); //for all ?>

Here's a more portable version (just for fun, it is not necessary in your case):

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT

try:
    from subprocess import DEVNULL # py3k
except ImportError:
    import os
    DEVNULL = open(os.devnull, 'wb')

text = u"René Descartes"
p = Popen(['espeak', '-b', '1'], stdin=PIPE, stdout=DEVNULL, stderr=STDOUT)
p.communicate(text.encode('utf-8'))
assert p.returncode == 0 # use appropriate for your program error handling here

I had the same issue, but my setup required a different solution.

I'm using the create-react-app-rewired package with a config-overrides.js file. Previously, I was using the addBabelPresets import (in the override() method) from customize-cra and decided to abstract those presets to a separate file. Coincidentally, this solved my problem.

I added useBabelRc() to the override() method in config-overrides.js and created a babel.config.js file with the following:

module.exports = {
    presets: [
        '@babel/preset-react',
        '@babel/preset-env'
    ],
}

You can use the the click function to trigger the click event on the selected element.

Example:

$( 'selector for your link' ).click ();

You can learn about various selectors in jQuery's documentation.

EDIT: like the commenters below have said; this only works on events attached with jQuery, inline or in the style of "element.onclick". It does not work with addEventListener, and it will not follow the link if no event handlers are defined. You could solve this with something like this:

var linkEl = $( 'link selector' );
if ( linkEl.attr ( 'onclick' ) === undefined ) {
    document.location = linkEl.attr ( 'href' );
} else {
    linkEl.click ();
}

Don't know about addEventListener though.

Instance methods need to be called from an instance. Your setLoanItem method is an instance method (it doesn't have the modifier static), which it needs to be in order to function (because it is setting a value on the instance that it's called on (this)).

You need to create an instance of the class before you can call the method on it:

Media media = new Media();
media.setLoanItem("Yes");

(Btw it would be better to use a boolean instead of a string containing "Yes".)

There is an illustrative example of how to create custom colormaps here. The docstring is essential for understanding the meaning of cdict. Once you get that under your belt, you might use a cdict like this:

cdict = {'red':   ((0.0, 1.0, 1.0), 
                   (0.1, 1.0, 1.0),  # red 
                   (0.4, 1.0, 1.0),  # violet
                   (1.0, 0.0, 0.0)), # blue

         'green': ((0.0, 0.0, 0.0),
                   (1.0, 0.0, 0.0)),

         'blue':  ((0.0, 0.0, 0.0),
                   (0.1, 0.0, 0.0),  # red
                   (0.4, 1.0, 1.0),  # violet
                   (1.0, 1.0, 0.0))  # blue
          }

Although the cdict format gives you a lot of flexibility, I find for simple gradients its format is rather unintuitive. Here is a utility function to help generate simple LinearSegmentedColormaps:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.colors as mcolors


def make_colormap(seq):
    """Return a LinearSegmentedColormap
    seq: a sequence of floats and RGB-tuples. The floats should be increasing
    and in the interval (0,1).
    """
    seq = [(None,) * 3, 0.0] + list(seq) + [1.0, (None,) * 3]
    cdict = {'red': [], 'green': [], 'blue': []}
    for i, item in enumerate(seq):
        if isinstance(item, float):
            r1, g1, b1 = seq[i - 1]
            r2, g2, b2 = seq[i + 1]
            cdict['red'].append([item, r1, r2])
            cdict['green'].append([item, g1, g2])
            cdict['blue'].append([item, b1, b2])
    return mcolors.LinearSegmentedColormap('CustomMap', cdict)


c = mcolors.ColorConverter().to_rgb
rvb = make_colormap(
    [c('red'), c('violet'), 0.33, c('violet'), c('blue'), 0.66, c('blue')])
N = 1000
array_dg = np.random.uniform(0, 10, size=(N, 2))
colors = np.random.uniform(-2, 2, size=(N,))
plt.scatter(array_dg[:, 0], array_dg[:, 1], c=colors, cmap=rvb)
plt.colorbar()
plt.show()

By the way, the for-loop

for i in range(0, len(array_dg)):
  plt.plot(array_dg[i], markers.next(),alpha=alpha[i], c=colors.next())

plots one point for every call to plt.plot. This will work for a small number of points, but will become extremely slow for many points. plt.plot can only draw in one color, but plt.scatter can assign a different color to each dot. Thus, plt.scatter is the way to go.
