To get the behavior you want you need to wait for the process to finish before you exit Main(). To be able to tell when your process is done you need to return a Task instead of a void from your function, you should never return void from a async function unless you are working with events.

A re-written version of your program that works correctly would be

class Program {     static void Main(string[] args)     {         Debug.WriteLine("Calling DoDownload");         var downloadTask = DoDownloadAsync();         Debug.WriteLine("DoDownload done");         downloadTask.Wait(); //Waits for the background task to complete before finishing.      }      private static async Task DoDownloadAsync()     {         WebClient w = new WebClient();          string txt = await w.DownloadStringTaskAsync("http://www.google.com/");         Debug.WriteLine(txt);     } } 

Because you can not await in Main() I had to do the Wait() function instead. If this was a application that had a SynchronizationContext I would do await downloadTask; instead and make the function this was being called from async.

Yet another method to solve: updating registry. In my case I could not alter GPO, and -UseBasicParsing breaks parts of the access to the website. Also I had a service user without log in permissions, so I could not log in as the user and run the GUI.
To fix,

1. log in as a normal user, run IE setup.
2. Then export this registry key: HKEY_USERS\S-1-5-21-....\SOFTWARE\Microsoft\Internet Explorer
3. In the .reg file that is saved, replace the user sid with the service account sid
4. Import the .reg file

In the file

I'd recommend using a CLR user defined function, if you already know how to program in C#, then the code would be;

using System.Data.SqlTypes;
using System.Net;

public partial class UserDefinedFunctions
{
 [Microsoft.SqlServer.Server.SqlFunction]
 public static SqlString http(SqlString url)
 {
  var wc = new WebClient();
  var html = wc.DownloadString(url.Value);
  return new SqlString (html);
 }
}

And here's installation instructions; https://blog.dotnetframework.org/2019/09/17/make-a-http-request-from-sqlserver-using-a-clr-udf/

You have an array, convert it to an object, something like:

data: [{"id": 3636, "is_default": true, "name": "Unit", "quantity": 1, "stock": "100000.00", "unit_cost": "0"}, {"id": 4592, "is_default": false, "name": "Bundle", "quantity": 5, "stock": "100000.00", "unit_cost": "0"}]

HttpClient is the newer of the APIs and it has the benefits of

• has a good async programming model
• being worked on by Henrik F Nielson who is basically one of the inventors of HTTP, and he designed the API so it is easy for you to follow the HTTP standard, e.g. generating standards-compliant headers
• is in the .Net framework 4.5, so it has some guaranteed level of support for the forseeable future
• also has the xcopyable/portable-framework version of the library if you want to use it on other platforms - .Net 4.0, Windows Phone etc.

If you are writing a web service which is making REST calls to other web services, you should want to be using an async programming model for all your REST calls, so that you don't hit thread starvation. You probably also want to use the newest C# compiler which has async/await support.

Note: It isn't more performant AFAIK. It's probably somewhat similarly performant if you create a fair test.

//BEWARE
//This works ONLY if the server returns 401 first
//The client DOES NOT send credentials on first request
//ONLY after a 401
client.Credentials = new NetworkCredential(userName, passWord); //doesnt work

//So use THIS instead to send credentials RIGHT AWAY
string credentials = Convert.ToBase64String(
    Encoding.ASCII.GetBytes(userName + ":" + password));
client.Headers[HttpRequestHeader.Authorization] = string.Format(
    "Basic {0}", credentials);

Downloading Wget is not necessary; the .NET Framework has web client classes built in.

$wc = New-Object system.Net.WebClient;
$sms = Read-Host "Enter SMS text";
$sms = [System.Web.HttpUtility]::UrlEncode($sms);
$smsResult = $wc.downloadString("http://smsserver/SNSManager/msgSend.jsp?uid&to=smartsms:*+001XXXXXX&msg=$sms&encoding=windows-1255")

In .NET Core, I managed to get a System.Net.Http.HttpClient with UseDefaultCredentials = true to pass through the authenticated user's Windows credentials to a back end service by using WindowsIdentity.RunImpersonated.

HttpClient client = new HttpClient(new HttpClientHandler { UseDefaultCredentials = true } );
HttpResponseMessage response = null;

if (identity is WindowsIdentity windowsIdentity)
{
    await WindowsIdentity.RunImpersonated(windowsIdentity.AccessToken, async () =>
    {
        var request = new HttpRequestMessage(HttpMethod.Get, url)
        response = await client.SendAsync(request);
    });
}

WebClient doesn't have a direct support for form data, but you can send a HTTP post by using the UploadString method:

Using client as new WebClient
    result = client.UploadString(someurl, "param1=somevalue&param2=othervalue")
End Using

The HtmlDocument class is a wrapper around the native IHtmlDocument2 COM interface.
You cannot easily create it from a string.

You should use the HTML Agility Pack.

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

I have tested your example, and while Request.QueryString is not convertible to a string neither implicit nor explicit still the .ToString() method returns the correct result.

Further more when concatenating with a string using the "+" operator as in your example it will also return the correct result (because this behaves as if .ToString() was called).

As such there is nothing wrong with your code, and I would suggest that your issue was because of a typo in your code writing "Querystring" instead of "QueryString".

And this makes more sense with your error message since if the problem is that QueryString is a collection and not a string it would have to give another error message.

Try this (Make sure you use System.Net):

public bool checkWebsite(string URL) {
   try {
      WebClient wc = new WebClient();
      string HTMLSource = wc.DownloadString(URL);
      return true;
   }
   catch (Exception) {
      return false;
   }
}

When the checkWebsite() function gets called, it tries to get the source code of the URL passed into it. If it gets the source code, it returns true. If not, it returns false.

Code Example:

//The checkWebsite command will return true:
bool websiteExists = this.checkWebsite("https://www.google.com");

//The checkWebsite command will return false:
bool websiteExists = this.checkWebsite("https://www.thisisnotarealwebsite.com/fakepage.html");

Using lambdas instead of IDisposable.

I have never been thrilled with the whole using/IDisposable idea. The problem is that it requires the caller to:

• know that they must use IDisposable
• remember to use 'using'.

My new preferred method is to use a factory method and a lambda instead

Imagine I want to do something with a SqlConnection (something that should be wrapped in a using). Classically you would do

using (Var conn = Factory.MakeConnection())
{
     conn.Query(....);
}

New way

Factory.DoWithConnection((conn)=>
{
    conn.Query(...);
}

In the first case the caller could simply not use the using syntax. IN the second case the user has no choice. There is no method that creates a SqlConnection object, the caller must invoke DoWithConnection.

DoWithConnection looks like this

void DoWithConnection(Action<SqlConnection> action)
{
   using (var conn = MakeConnection())
   {
       action(conn);
   }
}

MakeConnection is now private

The PowerShell is almost exactly the same.

$webclient = new-object System.Net.WebClient
$webclient.Credentials = new-object System.Net.NetworkCredential($username, $password, $domain)
$webpage = $webclient.DownloadString($url)

This is a recursive way that removes multiple occurrences of "endchar":

function TrimEnd(str, endchar) {_x000D_
  while (str.endsWith(endchar) && str !== "" && endchar !== "") {_x000D_
    str = str.slice(0, -1);_x000D_
  }_x000D_
  return str;_x000D_
}_x000D_
_x000D_
var res = TrimEnd("Look at me. I'm a string without dots at the end...", ".");_x000D_
console.log(res)

You can USE PyPDF2 package

#install pyDF2
pip install PyPDF2

# importing all the required modules
import PyPDF2

# creating an object 
file = open('example.pdf', 'rb')

# creating a pdf reader object
fileReader = PyPDF2.PdfFileReader(file)

# print the number of pages in pdf file
print(fileReader.numPages)

Follow this Documentation http://pythonhosted.org/PyPDF2/

Try this : very simple way

$('<tr><td>3</td></tr><tr><td>4</td></tr>').appendTo("#myTable tbody");

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>_x000D_
<table id="myTable">_x000D_
  <tbody>_x000D_
    <tr><td>1</td></tr>_x000D_
    <tr><td>2</td></tr>_x000D_
  </tbody>_x000D_
</table>

Just use margin or padding.

In your specific case, you could use margin:0 10px only on the 2nd <span>.

UPDATE

Here's a nice CSS3 solution (jsFiddle):

span {
    margin: 0 10px;
}

span:first-of-type {
    margin-left: 0;
}

span:last-of-type {
    margin-right: 0;
}

Advanced element selection using selectors like :nth-child(), :last-child, :first-of-type, etc. is supported since Internet Explorer 9.

at last

ddlProducer.Items.Insert(0, "");

what is the type of the field EventDate, since the ordering isn't correct i assume you don't have it set to some Date/Time representing type, but a string. And then the american way of writing dates is nasty to sort

It is usually not recommended to call flush explicitly unless it is necessary. Hibernate usually auto calls Flush at the end of the transaction and we should let it do it's work. Now, there are some cases where you might need to explicitly call flush where a second task depends upon the result of the first Persistence task, both being inside the same transaction.

For example, you might need to persist a new Entity and then use the Id of that Entity to do some other task inside the same transaction, on that case it's required to explicitly flush the entity first.

@Transactional
void someServiceMethod(Entity entity){
    em.persist(entity); 
    em.flush() //need to explicitly flush in order to use id in next statement
    doSomeThingElse(entity.getId());    
}

Also Note that, explicitly flushing does not cause a database commit, a database commit is done only at the end of a transaction, so if any Runtime error occurs after calling flush the changes would still Rollback.

Your Window is not implementing the necessary data binding notifications that the grid requires to use it as a data source, namely the INotifyPropertyChanged interface.

Your "Name2" string needs also to be a property and not a public variable, as data binding is for use with properties.

Implementing the necessary interfaces for using an object as a data source can be found here.

Starting in SQL Server 2017 the STRING_AGG function is available which simplifies the logic considerably:

select FieldA, string_agg(FieldB, '') as data
from yourtable
group by FieldA

See SQL Fiddle with Demo

In SQL Server you can use FOR XML PATH to get the result:

select distinct t1.FieldA,
  STUFF((SELECT distinct '' + t2.FieldB
         from yourtable t2
         where t1.FieldA = t2.FieldA
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,0,'') data
from yourtable t1;

See SQL Fiddle with Demo

1.

Type t = typeof(obj1);
if (t == typeof(int))

This is illegal, because typeof only works on types, not on variables. I assume obj1 is a variable. So, in this way typeof is static, and does its work at compile time instead of runtime.

2.

if (obj1.GetType() == typeof(int))

This is true if obj1 is exactly of type int. If obj1 derives from int, the if condition will be false.

3.

if (obj1 is int)

This is true if obj1 is an int, or if it derives from a class called int, or if it implements an interface called int.

This, from the masters themselves (K&R, 2nd ed., pg. 106):

// strcmp: return < 0 if s < t, 0 if s == t, > 0 if s > t
int strcmp(char *s, char *t) 
{
    int i;

    for (i = 0; s[i] == t[i]; i++)
        if (s[i] == '\0')
            return 0;
    return s[i] - t[i];
}

If you are running a really old version of nltk, then there is indeed no download module available (reference)

Try this:

import nltk
print(nltk.__version__)

As per the reference, anything after 0.9.5 should be fine

Go download HTMLAgilityPack, now! ;) Download LInk

This allows you to load and parse HTML. Then you can navigate the DOM and extract the inner values of all attributes. Seriously, it will take you about 10 lines of code at the maximum. It is one of the greatest free .net libraries out there.

Here is a sample:

            string htmlContents = new System.IO.StreamReader(resultsStream,Encoding.UTF8,true).ReadToEnd();

            HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
            doc.LoadHtml(htmlContents);
            if (doc == null) return null;

            string output = "";
            foreach (var node in doc.DocumentNode.ChildNodes)
            {
                output += node.InnerText;
            }

It's also worth checking that you've got "Enable 32-bit Applications" set to True in the advanced settings of the DefaultAppPool within IIS.

As others have said, you shouldn't be using for..in to iterate over an array.

for ( var i = 0, len = myArray.length; i < len; i++ ) { ... }

If you want cleaner syntax, you could use forEach:

myArray.forEach( function ( val, i ) { ... } );

If you want to use this method, make sure that you include the ES5 shim to add support for older browsers.

when ob1 is created then the constructor is called where "t.start()" is written but still run() method is not executed rather main() method is executed further. So why is this happening?

here your threads and main thread has equal priority.Execution of equal priority thread totally depends on the Thread schedular.You can't expect which to execute first.

join() method is used to wait until the thread on which it is called does not terminates, but here in output we see alternate outputs of the thread why??

Here your calling below statements from main thread.

     ob1.t.join();
     ob2.t.join();
     ob3.t.join();

So main thread waits for ob1.t,ob2.t,ob3.t threads to die(look into Thread#join doc).So all three threads executes successfully and main thread completes after that

I use Mutex in my solution for preventing multiple instances.

static Mutex mutex = null;
//A string that is the name of the mutex
string mutexName = @"Global\test";
//Prevent Multiple Instances of Application
bool onlyInstance = false;
mutex = new Mutex(true, mutexName, out onlyInstance);

if (!onlyInstance)
{
  MessageBox.Show("You are already running this application in your system.", "Already Running..", MessageBoxButton.OK);
  Application.Current.Shutdown();
}

package main

import (
    "fmt"
    "strings"
)

func main() {
    strs := strings.Split("127.0.0.1:5432", ":")
    ip := strs[0]
    port := strs[1]
    fmt.Println(ip, port)
}

Here is the definition for strings.Split

// Split slices s into all substrings separated by sep and returns a slice of
// the substrings between those separators.
//
// If s does not contain sep and sep is not empty, Split returns a
// slice of length 1 whose only element is s.
//
// If sep is empty, Split splits after each UTF-8 sequence. If both s
// and sep are empty, Split returns an empty slice.
//
// It is equivalent to SplitN with a count of -1.
func Split(s, sep string) []string { return genSplit(s, sep, 0, -1) }

Use the simplest one to check for future date

if(moment().diff(yourDate) >=  0)
     alert ("Past or current date");
else
     alert("It is a future date");

Look before you leap (LBYL):

if idx < len(array):
    array[idx]
else:
    # handle this

Easier to ask forgiveness than permission (EAFP):

try:
    array[idx]
except IndexError:
    # handle this

In Python, EAFP seems to be the popular and preferred style. It is generally more reliable, and avoids an entire class of bugs (time of check vs. time of use). All other things being equal, the try/except version is recommended - don't see it as a "last resort".

This excerpt is from the official docs linked above, endorsing using try/except for flow control:

This common Python coding style assumes the existence of valid keys or attributes and catches exceptions if the assumption proves false. This clean and fast style is characterized by the presence of many try and except statements.

Or for fun:

>>> ast.literal_eval('[%s]'%','.join(map(repr,s.split())))

The question is: "Sort Collection". So you can't use Collections.sort(List<T> l, Comparator<? super T> comparator).

Some tips:

For Collection type:

Comparator<String> defaultComparator = new Comparator<String>() {
   @Override
   public int compare(String o1, String o2) {
       return o1.compareTo(o2);
   }
};

Collection<String> collection = getSomeStringCollection();
String[] strings = collection.toArray(new String[collection.size()]);
Arrays.sort(strings, defaultComparator);
List<String> sortedStrings = Arrays.asList(strings);

Collection<String> collection = getSomeStringCollection();
List<String> list = new ArrayList(collection);
Collections.sort(list, defaultComparator);
collection = list; // if you wish

For List type:

List<String> list = getSomeStringList();
Collections.sort(list, defaultComparator);

For Set type:

Set<String> set = getSomeStringSet();
// Than steps like in 'For Collection type' section or use java.util.TreeSet
// TreeSet sample:
// Sorted using java.lang.Comparable.
Set<String> naturalSorted = new TreeSet(set);

Set<String> set = getSomeStringSet();
Set<String> sortedSet = new TreeSet(defaultComparator);
sortedSet.addAll(set);

Java 8 version. There is java.util.List#sort(Comparator<? super E> c) method

List<String> list = getSomeStringList();
list.sort(defaultComparator);

or

List<String> list = getSomeStringList();
list.sort((String o1, String o2) -> o1.compareTo(o2));

or for types that implements Comparable:

List<String> list = getSomeStringList();
list.sort(String::compareTo);

Just giving a more up to date answer in case someone sees this old post.

Adding "utc=False" when converting to datetime will remove the timezone component and keep only the date in a datetime64[ns] data type.

pd.to_datetime(df['Date'], utc=False)

You will be able to save it in excel without getting the error "ValueError: Excel does not support datetimes with timezones. Please ensure that datetimes are timezone unaware before writing to Excel."

Try this or purpose will solve with lesser no of steps

for (int i = 0; i < a.length; i++) 
{
    for (int k = i+1; k < a.length; k++) 
    {
        if (a[i] != a[k]) 
         {
            System.out.println(a[i]+"not the same with"+a[k]+"\n");
        }
    }
}

SQL is a declarative language, not a procedural language. That is, you construct a SQL statement to describe the results that you want. You are not telling the SQL engine how to do the work.

As a general rule, it is a good idea to let the SQL engine and SQL optimizer find the best query plan. There are many person-years of effort that go into developing a SQL engine, so let the engineers do what they know how to do.

Of course, there are situations where the query plan is not optimal. Then you want to use query hints, restructure the query, update statistics, use temporary tables, add indexes, and so on to get better performance.

As for your question. The performance of CTEs and subqueries should, in theory, be the same since both provide the same information to the query optimizer. One difference is that a CTE used more than once could be easily identified and calculated once. The results could then be stored and read multiple times. Unfortunately, SQL Server does not seem to take advantage of this basic optimization method (you might call this common subquery elimination).

Temporary tables are a different matter, because you are providing more guidance on how the query should be run. One major difference is that the optimizer can use statistics from the temporary table to establish its query plan. This can result in performance gains. Also, if you have a complicated CTE (subquery) that is used more than once, then storing it in a temporary table will often give a performance boost. The query is executed only once.

The answer to your question is that you need to play around to get the performance you expect, particularly for complex queries that are run on a regular basis. In an ideal world, the query optimizer would find the perfect execution path. Although it often does, you may be able to find a way to get better performance.

Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.

The best way to do this is probably to use a third party library.

There's an implementation of what you're looking for in jQuery UI jQuery UI and in dojo dojo. jQuery is more popular, but dojo allows you to declaratively define widgets in HTML, which sounds more like what you're looking for.

Which one you use will depend on your style, but both are developed for cross browser work, and both will be updated more often than copy and paste code.

To address the issue of the status bar iOS7, we can use the following code to Cordova / PhoneGap:

function onDeviceReady() {
    if (parseFloat(window.device.version) === 7.0) {
          document.body.style.marginTop = "20px";
    }
}

document.addEventListener('deviceready', onDeviceReady, false);

Anyway Cordova 3.1 will soon fix that this and other issues for iOS7.

I know I'm a bit late for that one, but I'll share what I did too, in case it helps someone else :

HashMap<String, HashMap> selects = new HashMap<String, HashMap>();

for(Map.Entry<String, HashMap> entry : selects.entrySet()) {
    String key = entry.getKey();
    HashMap value = entry.getValue();

    // do what you have to do here
    // In your case, another loop.
}

Other answers already hit the target. I just want to add an illustration for a quick catch.

You don't need to list ContactPhoneAreaCode1 and ContactPhoneNumber1

SELECT FirstName AS First_Name, 
LastName AS Last_Name, 
COALESCE(ContactPhoneAreaCode1, ContactPhoneNumber1) AS Contact_Phone 
FROM TABLE1

Supports entering y|ye|yes and case insensitive.

switch -regex ($someString.ToLower()) {
        "^y(es?)?$" {
            "You entered Yes." 
        }
        default { "You entered No." }
}

Yes. In Ruby the not equal to operator is:

!=

This code which you have written, is not producing correct BFS traversal: (This is the code you claimed is BFS, but in fact this is DFS!)

      System.out.print(root.element + " ");
      breadth(root.left);
      breadth(root.right);

In Eclipse Photon navigate to Windows > Preferences > Maven > User Settings > User Setting

For "User settings" Browse to the settings.xml of the maven. ex. in my case maven it is located on the path C:\Program Files\Apache Software Distribution\apache-maven-3.5.4\conf\Settings.xml

Depending on the Settings.xml the Local Repository gets automatically configured to the specified location.

I wanted to sort of add why you would do things that way to the already great answers.

No idea what language you are coming from, but assuming it is a static language, this sort of thing will look familiar. This is how you read a file in java

public class FileInput {

  public static void main(String[] args) {

    File file = new File("C:\\MyFile.txt");
    FileInputStream fis = null;
    BufferedInputStream bis = null;
    DataInputStream dis = null;

    try {
      fis = new FileInputStream(file);

      // Here BufferedInputStream is added for fast reading.
      bis = new BufferedInputStream(fis);
      dis = new DataInputStream(bis);

      // dis.available() returns 0 if the file does not have more lines.
      while (dis.available() != 0) {

      // this statement reads the line from the file and print it to
        // the console.
        System.out.println(dis.readLine());
      }

      // dispose all the resources after using them.
      fis.close();
      bis.close();
      dis.close();

    } catch (FileNotFoundException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

Ignoring the whole stream chaining thing, The idea is this

1. Initialize resource that needs to be cleaned up
2. use resource
3. make sure to clean it up

This is how you do it in ruby

File.open("readfile.rb", "r") do |infile|
    while (line = infile.gets)
        puts "#{counter}: #{line}"
        counter = counter + 1
    end
end

Wildly different. Breaking this one down

1. tell the File class how to initialize the resource
2. tell the file class what to do with it
3. laugh at the java guys who are still typing ;-)

Here, instead of handling step one and two, you basically delegate that off into another class. As you can see, that dramatically brings down the amount of code you have to write, which makes things easier to read, and reduces the chances of things like memory leaks, or file locks not getting cleared.

Now, its not like you can't do something similar in java, in fact, people have been doing it for decades now. It's called the Strategy pattern. The difference is that without blocks, for something simple like the file example, strategy becomes overkill due to the amount of classes and methods you need to write. With blocks, it is such a simple and elegant way of doing it, that it doesn't make any sense NOT to structure your code that way.

This isn't the only way blocks are used, but the others (like the Builder pattern, which you can see in the form_for api in rails) are similar enough that it should be obvious whats going on once you wrap your head around this. When you see blocks, its usually safe to assume that the method call is what you want to do, and the block is describing how you want to do it.

for more extendability for large scale apps use oop style with encapsulated fields.

Simple way :-

  class Fruit implements JsonSerializable {

        private $type = 'Apple', $lastEaten = null;

        public function __construct() {
            $this->lastEaten = new DateTime();
        }

        public function jsonSerialize() {
            return [
                'category' => $this->type,
                'EatenTime' => $this->lastEaten->format(DateTime::ISO8601)
            ];
        }
    }

echo json_encode(new Fruit()); //which outputs:

{"category":"Apple","EatenTime":"2013-01-31T11:17:07-0500"}

I have found a very easy solution! If you have a form and you want to have a custom submit button you can use some code like this:

<button type="submit">
    <img src="login.png" onmouseover="this.src='login2.png';" onmouseout="this.src='login.png';" />
</button>

Or just direct it to a link of a page.

Maybe it is not too late to add some info.

Sum:

The Func is a custom delegate defined in System namespace that allows you to point to a method with the same signature (as delegates do), using 0 to 16 input parameters and that must return something.

Nomenclature & how2use:

Func<input_1, input_2, ..., input1_6, output> funcDelegate = someMethod;

Definition:

public delegate TResult Func<in T, out TResult>(T arg);

Where it is used:

It is used in lambda expressions and anonymous methods.

You Probably Don't Need Moment.js Anymore

Moment is great time manipulation library but it's considered as a legacy project, and the team is recommending to use other libraries.

date-fns is one of the best lightweight libraries, it's modular, so you can pick the functions you need and reduce bundle size (issue & statement).

Another common argument against using Moment in modern applications is its size. Moment doesn't work well with modern "tree shaking" algorithms, so it tends to increase the size of web application bundles.

import { format } from 'date-fns' // 21K (gzipped: 5.8K)
import moment from 'moment' // 292.3K (gzipped: 71.6K)

Format date with date-fns:

// moment.js
moment().format('MM/DD/YYYY');
// => "12/18/2020"

// date-fns
import { format } from 'date-fns'
format(new Date(), 'MM/dd/yyyy');
// => "12/18/2020"

More on cheat sheet with the list of functions which you can use to replace moment.js: You-Dont-Need-Momentjs

If you just need something simple and more of a verification.

public String getKey(String key)
{
    if(map.containsKey(key)
    {
        return key;
    }
    return null;
}

Then you can search for any key.

System.out.println( "Does this key exist? : " + getKey("United") );

Too late but in case someone need it:

   fun setDrawableColor(drawable: Drawable, color: Int) :Drawable {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            drawable.colorFilter = BlendModeColorFilter(color, BlendMode.SRC_ATOP)
            return drawable
        } else {
            drawable.setColorFilter(color, PorterDuff.Mode.SRC_ATOP)
            return drawable
        }
    }

You can do it via ODBC. The steps to do it:

1. Install IBM SPSS Statistics Data File Driver. Standalone Driver is enough.
2. Create DNS via ODBC manager.
3. Use the data importer in Excel via ODBC by selecting created DNS.

You can use class loader which will read from classpath as ROOT path (without "/" in the beginning)

InputStream in = getClass().getClassLoader().getResourceAsStream("file.txt"); 
BufferedReader reader = new BufferedReader(new InputStreamReader(in));

Rename your variable name to myname, bacause name is a generic property of window and is not writable in the same window.

And replace

onclick='myfunction(\''" + name + "'\')'

With

onclick='myfunction(myname)'

Working example:

var myname = "Mathew";_x000D_
document.write('<button id="button" type="button" onclick="myfunction(myname);">click</button>');_x000D_
function myfunction(name) {_x000D_
    alert(name);_x000D_
}

If I remember correctly, you'll need to set the netbeans_jdkhome property in your netbeans config file. Should be in your etc/netbeans.conf file.

This should get your sorted:

• Highlight from the end of the first line, to the very beginning of the third line.
• Use the Ctrl + H to bring up the 'Find and Replace' window.
• The highlighed region will already be plased in the 'Find' textbox.
• Replace with: \r\n
• 'Replace All' will then remove all the additional line spaces not required.

Here's how it should look:

In Java 8 you can do this:

Instant inst = Instant.parse("2018-12-30T19:34:50.63Z"); 

// subtract 10 Days to Instant 
Instant value = inst.minus(Period.ofDays(10)); 
// print result 
System.out.println("Instant after subtracting Days: " + value); 

Here is a YUI compressor script (Byuic) that finds all the js and css down a path and compresses /(optionally) obfuscates them. Nice to integrate into a build process.

(Reputation not high enough to comment) The second part of John Petrone's answer works - no query needed. It will delete the type and all documents contained in that type, but that can just be re-created whenever you index a new document to that type.

Just to clarify: $ curl -XDELETE 'http://localhost:9200/twitter/tweet'

Note: this does delete the mapping! But as mentioned before, it can be easily re-mapped by creating a new document.

I ran into this and it ended up being I was opening the file with the text editor and not the java editor.

I wanted to comment on https://stackoverflow.com/users/607470/elroy-flynn response but the add comment only works after I have a rating of 50? not sure WTF that is...

I want to return odd numbers of an array

If i read that correctly, you want something like this?

List<Integer> getOddNumbers(int[] integers) {
  List<Integer> oddNumbers = new ArrayList<Integer>();
  for (int i : integers)
    if (i % 2 != 0)
      oddNumbers.add(i);
  return oddNumbers;
}

If you are on Mac OS X or Ubuntu, the problem is caused by the symlinks to the JDK. File | Invalidate Caches should help. If it doesn't, specify the JDK path to the direct JDK Home folder, not a symlink.

Invalidate Caches menu item is available under IntelliJ IDEA File menu.

Direct JDK path after the recent Apple Java update is:

/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

In IDEA you can configure the new JSDK in File | Project Structure, select SDKs on the left, then press [+] button, then specify the above JDK home path, you should get something like this:

format supports a percentage floating point precision type:

>>> print "{0:.0%}".format(1./3)
33%

If you don't want integer division, you can import Python3's division from __future__:

>>> from __future__ import division
>>> 1 / 3
0.3333333333333333

# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%

# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%

At least with Chrome, (I don't know about Firefox) You can drag the icon to the left of the URL in the browser to a folder location on your desktop and it will create a file that behaves as an internet shortcut.

I don't know if the file format is universal yet, however Chrome seems to know what to do with it.

The file produced is a .url file and contains the following:

[InternetShortcut] URL=http://www.accordingtothescriptures.org/prophecy/353prophecies.html

You can replace the URL with anything you'd like.

Your question answers itself ;) If og_date contains the date, it's probably a string, so og_date.value is undefined.

Simply use og_date.split('-') instead of og_date.value.split('-')

I think you have to include jQuery to use responseJSON.

Without jQuery, you could try with responseText and try like eval("("+req.responseText+")");

UPDATE:Please read the comment regarding eval, you can test with eval, but don't use it in working extension.

OR

use json_parse : it does not use eval

You have to specify the name of the custom view and its related model in Controller Action method.

public ActionResult About()
{            
   return View("NameOfViewYouWantToReturn",Model); 
}

If you have already committed the file and you are trying to ignore it by adding to the .gitignore file, Git will not ignore it. For that, you first have to do the below things:

git rm --cached FILENAME

If you are starting the project freshly and you want to add some files to Git ignore, follow the below steps to create a Git ignore file:

1. Navigate to your Git repository.
2. Enter "touch .gitignore" which will create a .gitignore file.

My approach is to detect current UID/GID, then create such user/group inside the container and execute the script under him. As a result all files he will create will match the user on the host (which is the script):

# get location of this script no matter what your current folder is, this might break between shells so make sure you run bash
LOCAL_DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

# get current IDs
USER_ID=$(id -u)
GROUP_ID=$(id -g)

echo "Mount $LOCAL_DIR into docker, and match the host IDs ($USER_ID:$GROUP_ID) inside the container."

docker run -v $LOCAL_DIR:/host_mount -i debian:9.4-slim bash -c "set -euo pipefail && groupadd -r -g $GROUP_ID lowprivgroup && useradd -u $USER_ID lowprivuser -g $GROUP_ID && cd /host_mount && su -c ./runMyScriptAsRegularUser.sh lowprivuser"

In Python 2.x, it is not guaranteed at all:

>>> False = 5
>>> 0 == False
False

So it could change. In Python 3.x, True, False, and None are reserved words, so the above code would not work.

In general, with booleans you should assume that while False will always have an integer value of 0 (so long as you don't change it, as above), True could have any other value. I wouldn't necessarily rely on any guarantee that True==1, but on Python 3.x, this will always be the case, no matter what.

you're comparing the result against a string ('false') not the built-in negative constant (false)

just use

if(ValidateForm() == false) {

or better yet

if(!ValidateForm()) {

also why are you calling validateForm twice?

>>> x = "2342.34"
>>> float(x)
2342.3400000000001

There you go. Use float (which behaves like and has the same precision as a C,C++, or Java double).

For example :

<div style="height:100px; width:100px; background:#000000"></div>

here.

you give css to div of height and width having 100px and background as black.

PS : try to avoid inline-css you can make external CSS and import in your html file.

you can refer here for CSS

hope this helps.

Long story short you need to create a launch file. So, from Terminal:

sudo vi /Library/LaunchDaemons/com.mysql.mysql.plist

(If you are not familiar with vi, then press i to start inserting text)

This should be the content of your file:

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>KeepAlive</key>
    <true />
    <key>Label</key>
    <string>com.mysql.mysqld</string>
    <key>ProgramArguments</key>
    <array>
      <string>/usr/local/mysql/bin/mysqld_safe</string>
      <string>--user=mysql</string>
    </array>
  </dict>
</plist>

press esc then : wq!enter

Then you need to give the file the right permissions and set it to load on startup.

sudo chown root:wheel /Library/LaunchDaemons/com.mysql.mysql.plist 
sudo chmod 644 /Library/LaunchDaemons/com.mysql.mysql.plist 
sudo launchctl load -w /Library/LaunchDaemons/com.mysql.mysql.plist

And that is it.

For completeness - adding to accepted answer above - in case you are interested in any sibling regardless of the element type you can use variation:

From your question, you are running python2.7 and Cygwin.

Python should be installed for windows, which from your question it seems it is. If "which python" prints out /usr/bin/python , then from the bash prompt you are running the cygwin version.

Set the Python Environmental variables appropriately , for instance in my case:

PY_HOME=C:\opt\Python27
PYTHONPATH=C:\opt\Python27;c:\opt\Python27\Lib

In that case run cygwin setup and uninstall everything python. After that run "which pydoc", if it shows

/usr/bin/pydoc

Replace /usr/bin/pydoc with

#! /bin/bash
 /cygdrive/c/WINDOWS/system32/cmd /c %PYTHONHOME%\Scripts\\pydoc.bat

Then add this to $PY_HOME/Scripts/pydoc.bat

rem wrapper for pydoc on Win32
@python c:\opt\Python27\Lib\pydoc.py %*

Now when you type in the cygwin bash prompt you should see:

$ pydoc
 pydoc - the Python documentation tool

 pydoc.py <name> ...
   Show text documentation on something.  <name> 
   may be the name of a Python keyword, topic,
   function, module, or package, or a dotted
   reference to a class or function within a
   module or module in a package.
...

Question is about merging two images, however in this specified case you shouldn't do that. You should put Content Image (ie. cover) into <img /> tag, and Style Image into CSS, why?

1. As I said the cover belongs to the content of the document, while that vinyl record and shadow are just a part of the page styles.
2. Such separation is much more convenient to use. User can easily copy that image. It's easier to index by web-spiders.
3. Finally, it's much easier to maintain.

So use a very simple code:

<div class="cover">
   <img src="/content/images/covers/movin-mountains.png" alt="Moving mountains by Pneuma" width="100" height="100" />
</div>

.cover {
    padding: 10px;
    padding-right: 100px;

    background: url(/style/images/cover-background.png) no-repeat;
}

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Attributes.Add("style", "cursor:help;");
    if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowState == DataControlRowState.Alternate)
    { 
        if (e.Row.RowType == DataControlRowType.DataRow)
        {                
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#E56E94'");
            e.Row.BackColor = Color.FromName("#E56E94");                
        }           
    }
    else
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='orange'");
            e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='gray'");
            e.Row.BackColor = Color.FromName("gray");                
        }           
    }
}

Seeing as Guava gets a mention, I thought I would also suggest Eclipse Collections (formerly known as GS Collections).

The following examples all return a List with a single item.

Lists.mutable.of("Just one item");
Lists.mutable.with("Or use with");
Lists.immutable.of("Maybe it must be immutable?");
Lists.immutable.with("And use with if you want");

There are similar methods for other collections.

I doubt very much a telnet library will ever be part of the .Net BCL, although you do have almost full socket support so it wouldnt be too hard to emulate a telnet client, Telnet in its general implementation is a legacy and dying technology that where exists generally sits behind a nice new modern facade. In terms of Unix/Linux variants you'll find that out the box its SSH and enabling telnet is generally considered poor practice.

You could check out: http://granados.sourceforge.net/ - SSH Library for .Net http://www.tamirgal.com/home/dev.aspx?Item=SharpSsh

You'll still need to put in place your own wrapper to handle events for feeding in input in a scripted manner.

You can use PostBackUrl="~/Confirm.aspx"

For example:

In your .aspx file

<asp:Button ID="btnConfirm" runat="server" Text="Confirm" PostBackUrl="~/Confirm.aspx" />

or in your .cs file

btnConfirm.PostBackUrl="~/Confirm.aspx"

Problem

The trim() method removes whitespace from both sides of a string.

Source

Solution

You can use a Javascript replace method to remove white space like

"hello world".replace(/\s/g, "");

Example

var out = "hello world".replace(/\s/g, "");_x000D_
console.log(out);

Modifying, or more correctly, adding additional HTTP headers is a great code debugging tool if nothing else.

When a URL request returns a redirect or an image there is no html "page" to temporarily write the results of debug code to - at least not one that is visible in a browser.

One approach is to write the data to a local log file and view that file later. Another is to temporarily add HTTP headers reflecting the data and variables being debugged.

I regularly add extra HTTP headers like X-fubar-somevar: or X-testing-someresult: to test things out - and have found a lot of bugs that would have otherwise been very difficult to trace.

You can use title attribute.

<img src="smiley.gif"  title="Smiley face"/>

You can change the source of image as you want.

And as @Gray commented:

You can also use the title on other things like <a ... anchors, <p>, <div>, <input>, etc. See: this

Load testing your API by using just ab is not enough. However, I think it's a great tool to give you a basic idea how your site is performant.

If you want to use the ab command in to test multiple API endpoints, with different data, all at the same time in background, you need to use "nohup" command. It runs any command even when you close the terminal.

I wrote a simple script that automates the whole process, feel free to use it: http://blog.ikvasnica.com/entry/load-test-multiple-api-endpoints-concurrently-use-this-simple-shell-script

By using nio in Java SE 7,

import java.nio.file.*;

Path path = Paths.get(filePathString);

if (Files.exists(path)) {
  // file exist
}

if (Files.notExists(path)) {
  // file is not exist
}

If both exists and notExists return false, the existence of the file cannot be verified. (maybe no access right to this path)

You can check if path is a directory or regular file.

if (Files.isDirectory(path)) {
  // path is directory
}

if (Files.isRegularFile(path)) {
  // path is regular file
}

Please check this Java SE 7 tutorial.

Try Add Exception: FireFox -> Tools -> Advanced -> View Certificates -> Servers -> Add Exception.

It's like asking what's the benefit of a hammer over a screwdriver. At an extremely high level, both do essentially the same thing, but at the implementation level it's important to select the optimal tool for what you're trying to accomplish. There are tasks that are difficult and time-consuming in c# but easy in f# - like trying to pound a nail with a screwdriver. You can do it, for sure - it's just not ideal.

Data manipulation is one example I can personally point to where f# really shines and c# can potentially be unwieldy. On the flip side, I'd say (generally speaking) complex stateful UI is easier in OO (c#) than functional (f#). (There would probably be some people who disagree with this since it's "cool" right now to "prove" how easy it is to do anything in F#, but I stand by it). There are countless others.

Let me emphasise that Docker doesn't even allow mixed characters.

Good: docker build -t myfirstechoimage:0.1 .

Bad: docker build -t myFirstEchoImage:0.1 .

CATALINA_HOME vs CATALINA_BASE

If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME.

In other words: CATALINA_HOME is required and CATALINA_BASE is optional.

CATALINA_HOME represents the root of your Tomcat installation.

Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, $CATALINA_BASE is the same as $CATALINA_HOME.

See: Apache Tomcat 7 - Introduction

Running with separate CATALINA_HOME and CATALINA_BASE is documented in RUNNING.txt which say:

The CATALINA_HOME and CATALINA_BASE environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.

You cannot configure CATALINA_HOME and CATALINA_BASE variables in the setenv script, because they are used to find that file.

For example:

(4.1) Tomcat can be started by executing one of the following commands:

  %CATALINA_HOME%\bin\startup.bat         (Windows)

  $CATALINA_HOME/bin/startup.sh           (Unix)

or

  %CATALINA_HOME%\bin\catalina.bat start  (Windows)

  $CATALINA_HOME/bin/catalina.sh start    (Unix)

Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When running with a separate CATALINA_HOME and CATALINA_BASE, the files and directories are split as following:

In CATALINA_BASE:

• bin - Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jar
• conf - Server configuration files (including server.xml)
• lib - Libraries and classes, as explained below
• logs - Log and output files
• webapps - Automatically loaded web applications
• work - Temporary working directories for web applications
• temp - Directory used by the JVM for temporary files>

In CATALINA_HOME:

• bin - Startup and shutdown scripts
• lib - Libraries and classes, as explained below
• endorsed - Libraries that override standard "Endorsed Standards". By default it's absent.

How to check

The easiest way to check what's your CATALINA_BASE and CATALINA_HOME is by running startup.sh, for example:

$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7

You may also check where the Tomcat files are installed, by dpkg tool as below (Debian/Ubuntu):

dpkg -L tomcat7-common

Generally you can just cast the variable to become a short.

You can also get problems like this that can be confusing. This is because the + operator promotes them to an int

Casting the elements won't help:

You need to cast the expression:

select DATEDIFF(dd, '12/30/1899', mydatefield)

Make sure you have the EntityFramework Nuget package installed for your project.

From @TonyDing's answer:

Right-click on the Solution from the Visual Studio Solution Explorer click the Manage Nuget packages for solution and install the EntityFramework

Once it is installed, I still had the error, but then did a reinstall per @papergodzilla's comment:

Update-Package -reinstall

and it resolved my issue

Do this in the Package Manager Console (View > Other windows > Package Manager Console).
Now everything is good!

Communicating through processes

Example:

Python: This python code block should return random temperatures.

# sensor.py

import random, time
while True:
    time.sleep(random.random() * 5)  # wait 0 to 5 seconds
    temperature = (random.random() * 20) - 5  # -5 to 15
    print(temperature, flush=True, end='')

Javascript (Nodejs): Here we will need to spawn a new child process to run our python code and then get the printed output.

// temperature-listener.js

const { spawn } = require('child_process');
const temperatures = []; // Store readings

const sensor = spawn('python', ['sensor.py']);
sensor.stdout.on('data', function(data) {

    // convert Buffer object to Float
    temperatures.push(parseFloat(data));
    console.log(temperatures);
});

NOTE: Pure Swift 3 (Xcode 8) example: Please try out the following sample code. It is the simple example of dataTask function of URLSession.

func simpleDataRequest() {

        //Get the url from url string
        let url:URL = URL(string: "YOUR URL STRING")!

        //Get the session instance
        let session = URLSession.shared

        //Create Mutable url request
        var request = URLRequest(url: url as URL)

        //Set the http method type
        request.httpMethod = "POST"

        //Set the cache policy
        request.cachePolicy = URLRequest.CachePolicy.reloadIgnoringCacheData

        //Post parameter
        let paramString = "key=value"

        //Set the post param as the request body
        request.httpBody = paramString.data(using: String.Encoding.utf8)

        let task = session.dataTask(with: request as URLRequest) {
            (data, response, error) in

            guard let _:Data = data as Data?, let _:URLResponse = response  , error == nil else {

                //Oops! Error occured.
                print("error")
                return
            }

            //Get the raw response string
            let dataString = String(data: data!, encoding: String.Encoding(rawValue: String.Encoding.utf8.rawValue))

            //Print the response
            print(dataString!)

        }

        //resume the task
        task.resume()

    }

There is no direct format specifier for this in the C language. Although I wrote this quick python snippet to help you understand the process step by step to roll your own.

#!/usr/bin/python

dec = input("Enter a decimal number to convert: ")
base = 2
solution = ""

while dec >= base:
    solution = str(dec%base) + solution
    dec = dec/base
if dec > 0:
    solution = str(dec) + solution

print solution

Explained:

dec = input("Enter a decimal number to convert: ") - prompt the user for numerical input (there are multiple ways to do this in C via scanf for example)

base = 2 - specify our base is 2 (binary)

solution = "" - create an empty string in which we will concatenate our solution

while dec >= base: - while our number is bigger than the base entered

solution = str(dec%base) + solution - get the modulus of the number to the base, and add it to the beginning of our string (we must add numbers right to left using division and remainder method). the str() function converts the result of the operation to a string. You cannot concatenate integers with strings in python without a type conversion.

dec = dec/base - divide the decimal number by the base in preperation to take the next modulo

if dec > 0: solution = str(dec) + solution - if anything is left over, add it to the beginning (this will be 1, if anything)

print solution - print the final number

var methods = [];
for (var key in foo.prototype) {
    if (typeof foo.prototype[key] === "function") {
         methods.push(key);
    }
}

You can simply loop over the prototype of a constructor and extract all methods.

PycURL does this beautifully.

Below is a short example. It will throw a pycurl.error if something is fishy, where you get a tuple with error code and a human readable message.

import pycurl

curl = pycurl.Curl()
curl.setopt(pycurl.CAINFO, "myFineCA.crt")
curl.setopt(pycurl.SSL_VERIFYPEER, 1)
curl.setopt(pycurl.SSL_VERIFYHOST, 2)
curl.setopt(pycurl.URL, "https://internal.stuff/")

curl.perform()

You will probably want to configure more options, like where to store the results, etc. But no need to clutter the example with non-essentials.

Example of what exceptions might be raised:

(60, 'Peer certificate cannot be authenticated with known CA certificates')
(51, "common name 'CN=something.else.stuff,O=Example Corp,C=SE' does not match 'internal.stuff'")

Some links that I found useful are the libcurl-docs for setopt and getinfo.

• http://curl.haxx.se/libcurl/c/curl_easy_setopt.html
• http://curl.haxx.se/libcurl/c/curl_easy_getinfo.html

Memory in SunHotSpot JVM is organized into three generations: young generation, old generation and permanent generation.

• Young Generation : the newly created objects are allocated to the young gen.
• Old Generation : If the new object requests for a larger heap space, it gets allocated directly into the old gen. Also objects which have survived a few GC cycles gets promoted to the old gen i.e long lived objects house in old gen.
• Permanent Generation : The permanent generation holds objects that the JVM finds convenient to have the garbage collector manage, such as objects describing classes and methods, as well as the classes and methods themselves.

FYI: The permanent gen is not considered a part of the Java heap.

How does the three generations interact/relate to each other? Objects(except the large ones) are first allocated to the young generation. If an object remain alive after x no. of garbage collection cycles it gets promoted to the old/tenured gen. Hence we can say that the young gen contains the short lived objects while the old gen contains the objects having a long life. The permanent gen does not interact with the other two generations.

I got the color range to be asymmetric simply by changing the symkey argument to FALSE

symm=F,symkey=F,symbreaks=T, scale="none"

Solved the color issue with colorRampPalette with the breaks argument to specify the range of each color, e.g.

colors = c(seq(-3,-2,length=100),seq(-2,0.5,length=100),seq(0.5,6,length=100))

my_palette <- colorRampPalette(c("red", "black", "green"))(n = 299)

Altogether

heatmap.2(as.matrix(SeqCountTable), col=my_palette, 
    breaks=colors, density.info="none", trace="none", 
        dendrogram=c("row"), symm=F,symkey=F,symbreaks=T, scale="none")

user:Array[]=[1,2,3];
if(this.user.length)
{
    console.log("user has contents");
}
else{
    console.log("user is empty");
}

descendant-or-self::*[contains(@prop,'Foo')]

Or:

/bla/a[contains(@prop,'Foo')]

Or:

/bla/a[position() <= 3]

Dissected:

descendant-or-self::

The Axis - search through every node underneath and the node itself. It is often better to say this than //. I have encountered some implementations where // means anywhere (decendant or self of the root node). The other use the default axis.

* or /bla/a

The Tag - a wildcard match, and /bla/a is an absolute path.

[contains(@prop,'Foo')] or [position() <= 3]

The condition within [ ]. @prop is shorthand for attribute::prop, as attribute is another search axis. Alternatively you can select the first 3 by using the position() function.

There don't seem to be a variable which holds exactly what you want.

However, quoting the docs:

Also available, inventory_dir is the pathname of the directory holding Ansible’s inventory host file, inventory_file is the pathname and the filename pointing to the Ansible’s inventory host file.

playbook_dir contains the playbook base directory.

And finally, role_path will return the current role’s pathname (since 1.8). This will only work inside a role.

Dependent on your setup, those or the $ pwd -based solution might be enough.

You can use QPython:

It has a Python Console, Editor, as well as Package Management / Installers

http://qpython.com/

It's an open source project with both Python 2 and Python 3 implementations. You can download the source and the Android .apk files directly from github.

QPython 2: https://github.com/qpython-android/qpython/releases

QPython 3: https://github.com/qpython-android/qpython3/releases

I spent the better part of a day fiddling with this problem. Turned out the RowBackground Property on the DataGrid - which I had set - was overriding all attempts to change it in . As soon as I deleted it, everything worked. (Same goes for Foreground set in DataGridTextColumn, by the way).

Angular 2, 4 and Angular 5 compatible!

You have provided so few details, so I'll try to answer your question without them.

You can use Interpolation:

<img src={{imagePath}} />

Or you can use a template expression:

<img [src]="imagePath" />

In a ngFor loop it might look like this:

<div *ngFor="let student of students">
   <img src={{student.ImagePath}} />
</div>

SQL is implemented as if a query was executed in the following order:

1. FROM clause
2. WHERE clause
3. GROUP BY clause
4. HAVING clause
5. SELECT clause
6. ORDER BY clause

For most relational database systems, this order explains which names (columns or aliases) are valid because they must have been introduced in a previous step.

So in Oracle and SQL Server, you cannot use a term in the GROUP BY clause that you define in the SELECT clause because the GROUP BY is executed before the SELECT clause.

There are exceptions though: MySQL and Postgres seem to have additional smartness that allows it.

mysqld --initialize to initialize the data directory then mysqld &

If you had already launched mysqld& without mysqld --initialize you might have to delete all files in your data directory

You can also modify /etc/my.cnf to add a custom path to your data directory like this :

[mysqld]
...  
datadir=/path/to/directory

Take a peek in platforms/android-2.1/data/res/layout/screen.xml of the SDK. It seems to define a title there. You can frequently examine layouts like this and borrow the style="?android:attr/windowTitleStyle" styles which you can then use and override in your own TextViews.

You may be able to even select the title for direct tweaking by doing:

TextView title = (TextView)findViewById(android.R.id.title);

Add

export PATH=$PATH:/home/me/play

to your ~/.profile and execute

source ~/.profile 

in order to immediately reflect changes to your current terminal instance.

Pillow is released with installation wheels on Windows:

We provide Pillow binaries for Windows compiled for the matrix of supported Pythons in both 32 and 64-bit versions in wheel, egg, and executable installers. These binaries have all of the optional libraries included

https://pillow.readthedocs.io/en/3.3.x/installation.html#basic-installation

Update: Python 3.6 is now supported by Pillow. Install with pip install pillow and check https://pillow.readthedocs.io/en/latest/installation.html for more information.

However, Python 3.6 is still in alpha and not officially supported yet, although the tests do all pass for the nightly Python builds (currently 3.6a4).

Failing that, downgrade to Python 3.5 or wait until 3.6 is supported by Pillow, probably closer to the 3.6's official release.

Wouldn't List<ArrayList<String>> 2dlist = new ArrayList<ArrayList<String>>(); be a better (more efficient) implementation?

To have the same flexibility in CONCAT_WS as in CONCAT (if you don't want the same separator between every member for instance) use the following:

SELECT CONCAT_WS("",affiliate_name,':',model,'-',ip,... etc)

Use replaceFirst function of String class. There are so many variants of replace function that you can use.

in my case, I was passing all the parameters but one of the parameter my code was passing a null value for string.

Eg: cmd.Parameters.AddWithValue("@userName", userName);

in the above case, if the data type of userName is string, I was passing userName as null.

You can do this with Jinja's tojson filter, which

Dumps a structure to JSON so that it’s safe to use in <script> tags [and] in any place in HTML with the notable exception of double quoted attributes.

For example, in your Python, write:

some_template.render(list_of_items=list_of_items)

... or, in the context of a Flask endpoint:

return render_template('your_template.html', list_of_items=list_of_items)

Then in your template, write this:

{% for item in list_of_items %}
<span onclick='somefunction({{item | tojson}})'>{{item}}</span><br>
{% endfor %}

(Note that the onclick attribute is single-quoted. This is necessary since |tojson escapes ' characters but not " characters in its output, meaning that it can be safely used in single-quoted HTML attributes but not double-quoted ones.)

Or, to use list_of_items in an inline script instead of an HTML attribute, write this:

<script>
const jsArrayOfItems = {{list_of_items | tojson}};
// ... do something with jsArrayOfItems in JavaScript ...
</script>

DON'T use json.dumps to JSON-encode variables in your Python code and pass the resulting JSON text to your template. This will produce incorrect output for some string values, and will expose you to XSS if you're trying to encode user-provided values. This is because Python's built-in json.dumps doesn't escape characters like < and > (which need escaping to safely template values into inline <script>s, as noted at https://html.spec.whatwg.org/multipage/scripting.html#restrictions-for-contents-of-script-elements) or single quotes (which need escaping to safely template values into single-quoted HTML attributes).

If you're using Flask, note that Flask injects a custom tojson filter instead of using Jinja's version. However, everything written above still applies. The two versions behave almost identically; Flask's just allows for some app-specific configuration that isn't available in Jinja's version.

For Scala >= 2.12, use Source.fromResource:

scala.io.Source.fromResource("located_in_resouces.any")

Hope you realise, java.util.Enumeration is different from the Java 1.5 Enum types.

You can simply use YourEnum.valueOf("String") to get the equivalent enum type.

Thus if your enum is defined as so:

public enum Day {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY, 
    THURSDAY, FRIDAY, SATURDAY
}

You could do this:

String day = "SUNDAY";

Day dayEnum = Day.valueOf(day);

You can take timestamp snapshots before and after, then repeat the experiments several times to average to results. There are also profilers that can do this for you.

From "Java Platform Performance: Strategies and Tactics" book:

With System.currentTimeMillis()

class TimeTest1 {
   public static void main(String[] args) {

      long startTime = System.currentTimeMillis();

      long total = 0;
      for (int i = 0; i < 10000000; i++) {
         total += i;
      }

      long stopTime = System.currentTimeMillis();
      long elapsedTime = stopTime - startTime;
      System.out.println(elapsedTime);
   }
}

With a StopWatch class

You can use this StopWatch class, and call start() and stop before and after the method.

class TimeTest2 {
   public static void main(String[] args) {

      Stopwatch timer = new Stopwatch().start();

      long total = 0;
      for (int i = 0; i < 10000000; i++) {
         total += i;
      }

      timer.stop();
      System.out.println(timer.getElapsedTime());
   }
}

2. check user table:

mysql> use mysql

3.Modify the configuration file

mysql default bind ip:127.0.0.1, if we want to remote visit services,just delete config

#Modify the configuration file
vi /usr/local/etc/my.cnf

#Comment out the ip-address option

# Only allow connections from localhost
#bind-address = 127.0.0.1

4.finally restart the services

brew services restart mysql

The same issue faced me with XAMPP 7 and opencart Arabic 3. Replacing localhost by the actual machine name reslove the issue.

You can track by $index if your data source has duplicate identifiers

e.g.: $scope.dataSource: [{id:1,name:'one'}, {id:1,name:'one too'}, {id:2,name:'two'}]

You can't iterate this collection while using 'id' as identifier (duplicate id:1).

WON'T WORK:

<element ng-repeat="item.id as item.name for item in dataSource">
  // something with item ...
</element>

but you can, if using track by $index:

<element ng-repeat="item in dataSource track by $index">
  // something with item ...
</element>

Add reference Project->References Microsoft XML, 6.0 and you can use example code:

    Dim xml As String

    xml = "<root><person><name>Me </name> </person> <person> <name>No Name </name></person></root> "
    Dim oXml As MSXML2.DOMDocument60
    Set oXml = New MSXML2.DOMDocument60
    oXml.loadXML xml
    Dim oSeqNodes, oSeqNode As IXMLDOMNode

    Set oSeqNodes = oXml.selectNodes("//root/person")
    If oSeqNodes.length = 0 Then
       'show some message
    Else
        For Each oSeqNode In oSeqNodes
             Debug.Print oSeqNode.selectSingleNode("name").Text
        Next
    End If 

be careful with xml node //Root/Person is not same with //root/person, also selectSingleNode("Name").text is not same with selectSingleNode("name").text

I was unable to get Nanoix's perl script to work, or other curl examples I had seen, so I started looking into the api myself in python. This worked fine for small files, but large files choked past available ram so I found some other nice chunking code that uses the api's ability to partial download. Gist here: https://gist.github.com/csik/c4c90987224150e4a0b2

Note the bit about downloading client_secret json file from the API interface to your local directory.

I was facing same problem when I installed JRE by Oracle and solved this problem after my research.

I moved the environment path C:\Program Files (x86)\Common Files\Oracle\Java\javapath below H:\Program Files\Java\jdk-13.0.1\bin

Like this:

Path

H:\Program Files\Java\jdk-13.0.1\bin
C:\Program Files (x86)\Common Files\Oracle\Java\javapath

OR

Path

%JAVA_HOME%
%JRE_HOME%

You can use os.stat(path) call

I was having the same issue with Moment.js. I've installed moment-timezone, but the issue wasn't resolved. Then, I did just what here it's exposed, set the timezone and it works like a charm:

moment(new Date({your_date})).zone("+08:00")

Thanks a lot!

To see of the curent time is greater or equal to 14:08:10 do this:

if (time() >= strtotime("14:08:10")) {
  echo "ok";
}

Depending on your input sources, make sure to account for timezone.

See PHP time() and PHP strtotime()

As AlienWebGuy said, you can use background-image. I'd suggest you use background, but it will need three more properties after the URL:

background: url("http://www.gentleface.com/i/free_toolbar_icons_16x16_black.png") 0 0 no-repeat;

Explanation: the two zeros are x and y positioning for the image; if you want to adjust where the background image displays, play around with these (you can use both positive and negative values, e.g: 1px or -1px).

No-repeat says you don't want the image to repeat across the entire background. This can also be repeat-x and repeat-y.

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

The javascript array has a constructor that accepts the length of the array:

let arr = new Array<number>(3);
console.log(arr); // [undefined × 3]

However, this is just the initial size, there's no restriction on changing that:

arr.push(5);
console.log(arr); // [undefined × 3, 5]

Typescript has tuple types which let you define an array with a specific length and types:

let arr: [number, number, number];

arr = [1, 2, 3]; // ok
arr = [1, 2]; // Type '[number, number]' is not assignable to type '[number, number, number]'
arr = [1, 2, "3"]; // Type '[number, number, string]' is not assignable to type '[number, number, number]'

With the latest versions of mock, you can use the really useful mock_open helper:

mock_open(mock=None, read_data=None)

A helper function to create a mock to replace the use of open. It works for open called directly or used as a context manager.

The mock argument is the mock object to configure. If None (the default) then a MagicMock will be created for you, with the API limited to methods or attributes available on standard file handles.

read_data is a string for the read method of the file handle to return. This is an empty string by default.

>>> from mock import mock_open, patch
>>> m = mock_open()
>>> with patch('{}.open'.format(__name__), m, create=True):
...    with open('foo', 'w') as h:
...        h.write('some stuff')

>>> m.assert_called_once_with('foo', 'w')
>>> handle = m()
>>> handle.write.assert_called_once_with('some stuff')

Angular routing : Manual navigation

First you need to import the angular router :

import {Router} from "@angular/router"

Then inject it in your component constructor :

constructor(private router: Router) { }

And finally call the .navigate method anywhere you need to "redirect" :

this.router.navigate(['/your-path'])

You can also put some parameters on your route, like user/5 :

this.router.navigate(['/user', 5])

Documentation: Angular official documentaiton

In config.inc.php in the top-level directory, set

$cfg['DefaultLang'] = 'en-utf-8'; // Language if no other language is recognized
// or
$cfg['Lang'] = 'en-utf-8'; // Force this language for all users

If Lang isn't set, you should be able to select the language in the initial welcome screen, and the language your browser prefers should be preselected there.

pyspark.sql.Column.contains() is only available in pyspark version 2.2 and above.

df.where(df.location.contains('google.com'))

You may be able to do this with CSS3 using calculations, however it would most likely be safer to use JavaScript.

Here is an example: http://jsfiddle.net/8TrTU/

Using JS you can change the height of the text, then simply bind this same calculation to a resize event, during resize so it scales while the user is making adjustments, or however you are allowing resizing of your elements.

As Douglas Leeder said you need a separate process for timeout to signal to. Workaround by exporting function to subshells and running subshell manually.

export -f echoFooBar
timeout 10s bash -c echoFooBar

PDF Hummus. see for http://pdfhummus.com/ - contains all required features for manipulation with PDF files except rendering.

Here is a short, flexible snippet to convert a datetime-string in a cross-browser-safe fashion as nicel detailed by @drankin2112.

var inputTimestamp = "2014-04-29 13:00:15"; //example

var partsTimestamp = inputTimestamp.split(/[ \/:-]/g);
if(partsTimestamp.length < 6) {
    partsTimestamp = partsTimestamp.concat(['00', '00', '00'].slice(0, 6 - partsTimestamp.length));
}
//if your string-format is something like '7/02/2014'...
//use: var tstring = partsTimestamp.slice(0, 3).reverse().join('-');
var tstring = partsTimestamp.slice(0, 3).join('-');
tstring += 'T' + partsTimestamp.slice(3).join(':') + 'Z'; //configure as needed
var timestamp = Date.parse(tstring);

Your browser should provide the same timestamp result as Date.parse with:

(new Date(tstring)).getTime()

You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg

public class MyResult {
    int returnCode;
    String errorMessage;
    // etc
}

public MyResult someMethod() {
    // impl here
}

Simple. This is how I did it:

1. XML Side:

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:tools="http://schemas.android.com/tools"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingLeft="@dimen/activity_horizontal_margin"
       android:paddingRight="@dimen/activity_horizontal_margin"
       tools:context="com.mbh.usbcom.MainActivity">
       <TextView
           android:id="@+id/tv_log"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"
           android:scrollbars="vertical"
           android:text="Log:" />
   </RelativeLayout>
   

2. Java side:

   tv_log = (TextView) findViewById(R.id.tv_log);
   tv_log.setMovementMethod(new ScrollingMovementMethod());
   

Bonus:

To let the text view scroll down as the text fill it, you have to add:

    android:gravity="bottom"

to the TextView xml file. It will scroll down automatically as more text comes in.

Of course you need to add the text using the append function instead of set text:

    tv_log.append("\n" + text);

I used it for Log purpose.

I hope this helps ;)

in a single try catch block you can do all the thing the best practice is to catch the error in different catch block if you want them to show with their own message for particular errors.

if( value ) {
}

will evaluate to true if value is not:

• null
• undefined
• NaN
• empty string ''
• 0
• false

typescript includes javascript rules.

I found DragSortListView worked well, although getting started on it could have been easier. Here's a brief tutorial on using it in Android Studio with an in-memory list:

1. Add this to the build.gradle dependencies for your app:

   compile 'asia.ivity.android:drag-sort-listview:1.0' // Corresponds to release 0.6.1
   

2. Create a resource for the drag handle ID by creating or adding to values/ids.xml:

   <resources>
       ... possibly other resources ...
       <item type="id" name="drag_handle" />

3. Create a layout for a list item that includes your favorite drag handle image, and assign its ID to the ID you created in step 2 (e.g. drag_handle).

4. Create a DragSortListView layout, something like this:

   <com.mobeta.android.dslv.DragSortListView
       xmlns:android="http://schemas.android.com/apk/res/android"
       xmlns:dslv="http://schemas.android.com/apk/res-auto"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       dslv:drag_handle_id="@id/drag_handle"
       dslv:float_background_color="@android:color/background_light"/>
   

5. Set an ArrayAdapter derivative with a getView override that renders your list item view.

       final ArrayAdapter<MyItem> itemAdapter = new ArrayAdapter<MyItem>(this, R.layout.my_item, R.id.my_item_name, items) { // The third parameter works around ugly Android legacy. http://stackoverflow.com/a/18529511/145173
           @Override public View getView(int position, View convertView, ViewGroup parent) {
               View view = super.getView(position, convertView, parent);
               MyItem item = getItem(position);
               ((TextView) view.findViewById(R.id.my_item_name)).setText(item.getName());
               // ... Fill in other views ...
               return view;
           }
       };
   
       dragSortListView.setAdapter(itemAdapter);
   

6. Set a drop listener that rearranges the items as they are dropped.

       dragSortListView.setDropListener(new DragSortListView.DropListener() {
           @Override public void drop(int from, int to) {
               MyItem movedItem = items.get(from);
               items.remove(from);
               if (from > to) --from;
               items.add(to, movedItem);
               itemAdapter.notifyDataSetChanged();
           }
       });
   

What is the exact error message? #1062 means duplicate entry violating a primary key constraint for a column -- which boils down to the point that you cannot have two of the same values in the column. The error message should tell you which of your columns is constrained, I'm guessing "shares".

Assuming you don't have extraneous whitespace:

with open('file') as f:
    w, h = [int(x) for x in next(f).split()] # read first line
    array = []
    for line in f: # read rest of lines
        array.append([int(x) for x in line.split()])

You could condense the last for loop into a nested list comprehension:

with open('file') as f:
    w, h = [int(x) for x in next(f).split()]
    array = [[int(x) for x in line.split()] for line in f]

A line feed means moving one line forward. The code is \n.
A carriage return means moving the cursor to the beginning of the line. The code is \r.

Windows editors often still use the combination of both as \r\n in text files. Unix uses mostly only the \n.

The separation comes from typewriter times, when you turned the wheel to move the paper to change the line and moved the carriage to restart typing on the beginning of a line. This was two steps.

   public string GetXMLAsString(XmlDocument myxml)
    {
        using (var stringWriter = new StringWriter())
        {
            using (var xmlTextWriter = XmlWriter.Create(stringWriter))
            {
               myxml.WriteTo(xmlTextWriter);
               return stringWriter.ToString();
            }

        }    
}

Had same issue. This configuration setting solved the issue.

<system.webServer>
    .....
    <modules runAllManagedModulesForAllRequests="true" />
    .....
</system.webServer>

As explained in http://www.britishdeveloper.co.uk/2010/06/dont-use-modules-runallmanagedmodulesfo.html above solution should be avoided. Use this instead. Same solution is provided by Lopsided also. Keeping it here to let users avoid implementing the first working solution.

<modules>
  <remove name="UrlRoutingModule-4.0" />
  <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  <!-- any other modules you want to run in MVC e.g. FormsAuthentication, Roles etc. -->
</modules>

The functions getElementById and getElementsByClassName are very specific, while querySelector and querySelectorAll are more elaborate. My guess is that they will actually have a worse performance.

Also, you need to check for the support of each function in the browsers you are targetting. The newer it is, the higher probability of lack of support or the function being "buggy".

While doing my own server side JS experimentation I ended up using teajs. It conforms to common.js, is based on V8 AND is the only project that I know of that provides 'mod_teajs' apache server module.

In my opinion Node.js server is not production ready and lacks too many features - Apache is battle tested and the right way to do SSJS.

If you need to access this as a server-side control (e.g. you want to add data attributes to a link, as I did), then there is a way to do what you want; however, you don't use the Hyperlink or HtmlAnchor controls to do it. Create a literal control and then add in "Your Text" as the text for the literal control (or whatever else you need to do that way). It's hacky, but it works.

CASE WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

The leading ', ' and trailing ',' are added so that you can handle the match regardless of where it is in the string (first entry, last entry, or anywhere in between).

That said, why are you storing data you want to search on as a comma-separated string? This violates all kinds of forms and best practices. You should consider normalizing your schema.

In addition: don't use 'single quotes' as identifier delimiters; this syntax is deprecated. Use [square brackets] (preferred) or "double quotes" if you must. See "string literals as column aliases" here: http://msdn.microsoft.com/en-us/library/bb510662%28SQL.100%29.aspx

EDIT If you have multiple values, you can do this (you can't short-hand this with the other CASE syntax variant or by using something like IN()):

CASE 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, lactulose,%' 
  WHEN ', ' + dbo.Table.Column +',' LIKE '%, amlodipine,%' 
  THEN 'BP Medication' ELSE '' END AS [BP Medication]

If you have more values, it might be worthwhile to use a split function, e.g.

USE tempdb;
GO

CREATE FUNCTION dbo.SplitStrings(@List NVARCHAR(MAX))
RETURNS TABLE
AS
   RETURN ( SELECT DISTINCT Item FROM
       ( SELECT Item = x.i.value('(./text())[1]', 'nvarchar(max)')
         FROM ( SELECT [XML] = CONVERT(XML, '<i>'
         + REPLACE(@List,',', '</i><i>') + '</i>').query('.')
           ) AS a CROSS APPLY [XML].nodes('i') AS x(i) ) AS y
       WHERE Item IS NOT NULL
   );
GO

CREATE TABLE dbo.[Table](ID INT, [Column] VARCHAR(255));
GO

INSERT dbo.[Table] VALUES
(1,'lactulose, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(2,'lactulite, Lasix (furosemide), lactulose, propranolol, rabeprazole, sertraline,'),
(3,'lactulite, Lasix (furosemide), oxazepam, propranolol, rabeprazole, sertraline,'),
(4,'lactulite, Lasix (furosemide), lactulose, amlodipine, rabeprazole, sertraline,');

SELECT t.ID
  FROM dbo.[Table] AS t
  INNER JOIN dbo.SplitStrings('lactulose,amlodipine') AS s
  ON ', ' + t.[Column] + ',' LIKE '%, ' + s.Item + ',%'
  GROUP BY t.ID;
GO

Results:

ID
----
1
2
4

I had a similar problem; the anchor text in my Bootstrap4 navbar wasn't centered. Simply added text-center in the anchor's class.

Try this JS sollutuion:

var xStart, yStart = 0; 

document.addEventListener('touchstart', function(e) {
    xStart = e.touches[0].screenX;
    yStart = e.touches[0].screenY;
}); 

document.addEventListener('touchmove', function(e) {
    var xMovement = Math.abs(e.touches[0].screenX - xStart);
    var yMovement = Math.abs(e.touches[0].screenY - yStart);
    if((yMovement * 3) > xMovement) {
        e.preventDefault();
    }
});

Prevents default Safari scrolling and bounce gestures without detaching your touch event listeners.

The existing answers said could join() each thread.

But there are several ways to get the thread array / list:

• Add the Thread into a list on creation.
• Use ThreadGroup to manage the threads.

Following code will use the ThreadGruop approach. It create a group first, then when create each thread specify the group in constructor, later could get the thread array via ThreadGroup.enumerate()

        public int getCount() {
            return count;

The main thread will wait for all threads in the group to finish.

You can make it with timeout:

This will be visible: timeout 5

This will not be visible timeout 5 >nul

If you render the Recaptcha on a callback

<script src="https://www.google.com/recaptcha/api.js?onload=onloadCallback&render=explicit" async defer></script>

using an empty DIV as a placeholder

<div id='html_element'></div>

then you can specify an optional function call on a successful CAPTCHA response

var onloadCallback = function() {
    grecaptcha.render('html_element', {
      'sitekey' : 'your_site_key',
      'callback' : correctCaptcha
    });
  };

The recaptcha response will then be sent to the 'correctCaptcha' function.

var correctCaptcha = function(response) {
    alert(response);
};

All of this was from the Google API notes :

Google Recaptcha v2 API Notes

I'm a bit unsure why you would want to do this. Normally you would send the g-recaptcha-response field along with your Private key to safely validate server-side. Unless you wanted to disable the submit button until the recaptcha was sucessful or such - in which case the above should work.

Hope this helps.

It's the ternary form of the if-else operator. The above statement basically reads like this:

if ($add_review) then {
    return FALSE; //$add_review evaluated as True
} else {
    return $arg //$add_review evaluated as False
}

See here for more details on ternary op in PHP: http://www.addedbytes.com/php/ternary-conditionals/

Compare with glob, I recommend pathlib, filter one pattern is very simple.

from pathlib import Path

p = Path(YOUR_PATH)
filtered = [x for x in p.glob("**/*") if not x.name.startswith("eph")]

and if you want to filter more complex pattern, you can define a function to do that, just like:

def not_in_pattern(x):
    return (not x.name.startswith("eph")) and not x.name.startswith("epi")


filtered = [x for x in p.glob("**/*") if not_in_pattern(x)]

use that code, you can filter all files that start with eph or start with epi.

basically hidden fields will be more useful and advantages to use with multi step form. we can use hidden fields to pass one step information to next step using hidden and keep it forwarding till the end step.

1. CSRF tokens.

Cross-site request forgery is a very common website vulnerability. Requiring a secret, user-specific token in all form submissions will prevent CSRF attacks since attack sites cannot guess what the proper token is and any form submissions they perform on the behalf of the user will always fail.

2. Save state in multi-page forms.

If you need to store what step in a multi-page form the user is currently on, use hidden input fields. The user doesn't need to see this information, so hide it in a hidden input field.

General rule: Use the field to store anything that the user doesn't need to see, but that you want to send to the server on form submission.

I see users in comments wondering how to disable cell editing while allowing row deletion : I managed to do this by setting all columns individually to read only, instead of the DataGrid itself.

<DataGrid IsReadOnly="False">
    <DataGrid.Columns>
        <DataGridTextColumn IsReadOnly="True"/>
        <DataGridTextColumn IsReadOnly="True"/>
    </DataGrid.Columns>
</DataGrid>

Here is a sample poor man's solution for a trigger implementing tracking of changes on db objects ( via DDL stateements ) on a sql server 2005 / 2008 database. I contains also a simple sample of how-to enforce the usage of required someValue xml tag in the source code for each sql command ran on the database + the tracking of the current db version and type ( dev , test , qa , fb , prod) One could extend it with additional required attributes such as , etc. The code is rather long - it creates the empty database + the needed tracking table structure + required db functions and the populating trigger all running under a [ga] schema.

I wrote a small function for this repeating task:

count_pct <- function(df) {
  return(
    df %>%
      tally %>% 
      mutate(n_pct = 100*n/sum(n))
  )
}

I can then use it like:

mtcars %>% 
  group_by(cyl) %>% 
  count_pct

It returns:

# A tibble: 3 x 3
    cyl     n n_pct
  <dbl> <int> <dbl>
1     4    11  34.4
2     6     7  21.9
3     8    14  43.8

So Nodejs comes with the default global variable called '__fileName' that holds the current file being executed My advice is to pass the __fileName to a service from any file , so that the retrieval of the fileName is made dynamic

Below, I make use of the fileName string and then split it based on the path.sep. Note path.sep avoids issues with posix file seperators and windows file seperators (issues with '/' and '\'). It is much cleaner. Getting the substring and getting only the last seperated name and subtracting it with the actulal length by 3 speaks for itself.

You can write a service like this (Note this is in typescript , but you can very well write it in js )

export class AppLoggingConstants {

    constructor(){

    }
      // Here make sure the fileName param is actually '__fileName'
    getDefaultMedata(fileName: string, methodName: string) {
        const appName = APP_NAME;
        const actualFileName = fileName.substring(fileName.lastIndexOf(path.sep)+1, fileName.length - 3);
        //const actualFileName = fileName;
     return appName+ ' -- '+actualFileName;
    }


}

export const AppLoggingConstantsInstance = new AppLoggingConstants();

@user1417684 and @chris-foster are right!

excerpt from working code (without error handling):

var SubItemModel = mongoose.model('subitems', SubItemSchema);
var ItemModel    = mongoose.model('items', ItemSchema);

var new_sub_item_model = new SubItemModel(new_sub_item_plain);
new_sub_item_model.save(function (error, new_sub_item) {

  var new_item = new ItemModel(new_item);
  new_item.subitem = new_sub_item._id;
  new_item.save(function (error, new_item) {
    // so this is a valid way to populate via the Model
    // as documented in comments above (here @stack overflow):
    ItemModel.populate(new_item, { path: 'subitem', model: 'subitems' }, function(error, new_item) {
      callback(new_item.toObject());
    });
    // or populate directly on the result object
    new_item.populate('subitem', function(error, new_item) {
      callback(new_item.toObject());
    });
  });

});

Really, I tested saving values like 'é' and 'e' in column with unique index and they cause duplicate error on both 'utf8_unicode_ci' and 'utf8_general_ci'. You can save them only in 'utf8_bin' collated column.

And mysql docs (in http://dev.mysql.com/doc/refman/5.7/en/charset-applications.html) suggest into its examples set 'utf8_general_ci' collation.

[mysqld]
character-set-server=utf8
collation-server=utf8_general_ci

This is an old question, and the answers here seem to mostly advocate for using mousedown and mouseup to keep track of whether a button is pressed. But as others have pointed out, mouseup will only fire when performed within the browser, which can lead to losing track of the button state.

However, MouseEvent (now) indicates which buttons are currently pushed:

• For all modern browsers (except Safari) use MouseEvent.buttons
• For Safari, use MouseEvent.which (buttons will be undefined for Safari) Note: which uses different numbers from buttons for Right and Middle clicks.

When registered on document, mousemove will fire immediately as soon as the cursor reenters the browser, so if the user releases outside then the state will be updated as soon as they mouse back inside.

A simple implementation might look like:

var leftMouseButtonOnlyDown = false;

function setLeftButtonState(e) {
  leftMouseButtonOnlyDown = e.buttons === undefined 
    ? e.which === 1 
    : e.buttons === 1;
}

document.body.onmousedown = setLeftButtonState;
document.body.onmousemove = setLeftButtonState;
document.body.onmouseup = setLeftButtonState;

If more complicated scenarios are required (different buttons/multiple buttons/control keys), check out the MouseEvent docs. When/if Safari lifts its game, this should get easier.

My suggestions :

• Keep the program modular. Keep the Calculate class in a separate Calculate.java file and create a new class that calls the main method. This would make the code readable.

• For setting the values in the number, use constructors. Do not use like the methods you have used above like :

  public void setNumber(double fnum, double snum){ this.fn = fnum; this.sn = snum; }

  Constructors exists to initialize the objects.This is their job and they are pretty good at it.

• Getters for members of Calculate class seem in place. But setters are not. Getters and setters serves as one important block in the bridge of efficient programming with java. Put setters for fnum and snum as well

• In the main class, create a Calculate object using the new operator and the constructor in place.

• Call the getAnswer() method with the created Calculate object.

Rest of the code looks fine to me. Be modular. You could read your program in a much better way.

Here is my modular piece of code. Two files : Main.java & Calculate.java

Calculate.java

public class Calculate {


private double fn;
private double sn;
private char op;

    public double getFn() {
        return fn;
    }

    public void setFn(double fn) {
        this.fn = fn;
    }

    public double getSn() {
        return sn;
    }

    public void setSn(double sn) {
        this.sn = sn;
    }

    public char getOp() {
        return op;
    }

    public void setOp(char op) {
        this.op = op;
    }



    public Calculate(double fn, double sn, char op) {
        this.fn = fn;
        this.sn = sn;
        this.op = op;
    }


public void getAnswer(){
    double ans;
    switch (getOp()){
        case '+': 
            ans = add(getFn(), getSn());
            ansOutput(ans);
            break;
        case '-': 
            ans = sub (getFn(), getSn());
            ansOutput(ans);
            break;
        case '*': 
            ans = mul (getFn(), getSn());
            ansOutput(ans);
            break;
        case '/': 
            ans = div (getFn(), getSn());
            ansOutput(ans);
            break;
        default:
            System.out.println("--------------------------");
            System.out.println("Invalid choice of operator");
            System.out.println("--------------------------");
        }
    }
    public static double add(double x,double y){
        return x + y;
    }
    public static double sub(double x, double y){
        return x - y;
    }
    public static double mul(double x, double y){
        return x * y;
    }
    public static double div(double x, double y){
        return x / y;
    }

    public static void ansOutput(double x){
        System.out.println("----------- -------");
        System.out.printf("the answer is %.2f\n", x);
        System.out.println("-------------------");
    }
}

Main.java

public class Main {
    public static void main(String args[])
    {
        Calculate obj = new Calculate(1,2,'+');
        obj.getAnswer();
    }
}

Just finish it up.

string sqlCommand = "SELECT * FROM TABLE";
string connectionString = "blahblah";

DataSet ds = GetDataSet(sqlCommand, connectionString);

DataSet GetDataSet(string sqlCommand, string connectionString)
{
    DataSet ds = new DataSet();
    using (SqlCommand cmd = new SqlCommand(
        sqlCommand, new SqlConnection(connectionString)))
    {
        cmd.Connection.Open();
        DataTable table = new DataTable();
        table.Load(cmd.ExecuteReader());
        ds.Tables.Add(table);
    }
    return ds;
}

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

Selecting a HTTP response code is quite an easy task and can be described by simple rules. The only tricky part which is often forgotten is paragraph 6.5 from RFC 7231:

Except when responding to a HEAD request, the server SHOULD send a representation containing an explanation of the error situation, and whether it is a temporary or permanent condition.

Rules are as following:

1. If request was successful, then return 2xx code (3xx for redirect). If there was an internal logic error on a server, then return 5xx. If there is anything wrong in client request, then return 4xx code.
2. Look through available response code from selected category. If one of them has a name which matches well to your situation, you can use it. Otherwise just fallback to x00 code (200, 400, 500). If you doubt, fallback to x00 code.
3. Return error description in response body. For 4xx codes it must contain enough information for client developer to understand the reason and fix the client. For 5xx because of security reasons no details must be revealed.
4. If client needs to distinguish different errors and have different reaction depending on it, define a machine readable and extendible error format and use it everywhere in your API. It is good practice to make that from very beginning.
5. Keep in mind that client developer may do strange things and try to parse strings which you return as human readable description. And by changing the strings you will break such badly written clients. So always provide machine readable description and try to avoid reporting additional information in text.

So in your case I'd returned 400 error and something like this if "Roman" is obtained from user input and client must have specific reaction:

{
    "error_type" : "unsupported_resource",
    "error_description" : "\"Roman\" is not supported"
}

or a more generic error, if such situation is a bad logic error in a client and is not expected, unless developer made something wrong:

{
    "error_type" : "malformed_json",
    "error_description" : "\"Roman\" is not supported for \"requestedResource\" field"
}

No, it's not possible, browsers have their own ways to implement tooltip. All you can do is to create some div that behaves like an HTML tooltip (mostly it's just 'show on hover') with Javascript, and then style it the way you want.

With this, you wouldn't have to worry about browser's zooming in or out, since the text inside the tooltip div is an actual HTML, it would scale accordingly.

See Jonathan's post for some good resource.

Remember that your suggestions makes it difficult for clients to communicate with the server. They need to understand your innovative solution and encrypt the data accordingly, this model is not so good for public API (unless you are amazon\yahoo\google..).

Anyways, if you must encrypt the body content I would suggest you to check out existing standards and solutions like:

XML encryption (W3C standard)

You can use menu left sidebar collapse accordion, animated with right arrow

As already said, getElementsByClassName returns a HTMLCollection, which is defined as

[Exposed=Window]
interface HTMLCollection {
  readonly attribute unsigned long length;
  getter Element? item(unsigned long index);
  getter Element? namedItem(DOMString name);
};

Previously, some browsers returned a NodeList instead.

[Exposed=Window]
interface NodeList {
  getter Node? item(unsigned long index);
  readonly attribute unsigned long length;
  iterable<Node>;
};

The difference is important, because DOM4 now defines NodeLists as iterable.

According to Web IDL draft,

Objects implementing an interface that is declared to be iterable support being iterated over to obtain a sequence of values.

Note: In the ECMAScript language binding, an interface that is iterable will have “entries”, “forEach”, “keys”, “values” and @@iterator properties on its interface prototype object.

That means that, if you want to use forEach, you can use a DOM method which returns a NodeList, like querySelectorAll.

document.querySelectorAll(".myclass").forEach(function(element, index, array) {
  // do stuff
});

Note this is not widely supported yet. Also see forEach method of Node.childNodes?

If you're okay with ES2017, await is good:

const DEF_DELAY = 1000;

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms || DEF_DELAY));
}

await sleep(100);

Note that the await part needs to be in an async function:

//IIAFE (immediately invoked async function expression)
(async()=>{
  //Do some stuff
  await sleep(100);
  //Do some more stuff
})()

Something we've starting doing at work is the ActiveSupport Ordered Hash

Which allows you to define your configuration cleanly inside the environment files e.g.

config.service = ActiveSupport::OrderedOptions.new
config.service.api_key = ENV['SERVICE_API_KEY']
config.service.shared_secret = ENV['SERVICE_SHARED_SECRET']

If you are using 11G XE with Windows, along with tns listener restart, make sure Windows Event Log service is started.

First, go to the following URL and download the mobile_detect.php file:

http://code.google.com/p/php-mobile-detect/

Insert the following code on your index or home page:

<?php
@include("Mobile_Detect.php");
$detect = new Mobile_Detect();
if ($detect->isMobile() && isset($_COOKIE['mobile']))
{
$detect = "false";
}
elseif ($detect->isMobile())
{
header("Location:http://www.yourmobiledirectory.com");
}
?>

• A extends B:

  A and B are both classes or both interfaces

• A implements B

  A is a class and B is an interface

• The remaining case where A is an interface and B is a class is not legal in Java.

For Print Result to text file

we can follow

echo "test data" > test.txt

This will create test.txt file and written "test data"

If you want to append then

echo "test data" >> test.txt

I had the same problem with Xcode Version 6.1 (6A1052d). I think the problem appears if you renamed your App / Xcode Project.

My solution was to add the module name in the interface builder manually.

Use:

window.location = "http://my.url.here";

Here's some quick-n-dirty code that uses jQuery to do what you want. I highly recommend using jQuery. It'll make things a lot more easier for you, especially since you're new to JavaScript.

<select id = "pricingOptions" name = "pricingOptions">
    <option value = "500">Option A</option>
    <option value = "1000">Option B</option>
</select>

<script type = "text/javascript" language = "javascript">
    jQuery(document).ready(function() {
        jQuery("#pricingOptions").change(function() {
            if(this.options[this.selectedIndex].value == "500") {
                window.location = "http://example.com/foo.php?option=500";
            }
        });
    });
</script>

This one is less native, but may be the fastest...

zeroPad = function (num, count) {
    var pad = (num + '').length - count;
    while(--pad > -1) {
        num = '0' + num;
    }
    return num;
};

If you need something quick, datetime_object.date() gives you a date of a datetime object.

You might output your DataFrame as a csv file and then use mysqlimport to import your csv into your mysql.

As far as I can tell,

• hstore as it currently exists (in Postgresql 9.3) does not allow for nesting other objects and arrays as the values of its key/value pairs. however a future hstore patch will allow for nesting. this patch will not be in the 9.4 release and may not be included any time soon.

• json as it currently exists does allow for nesting, but is text-based, and does not allow for indexing, thus it is "slow"

• jsonb that will be released with 9.4 will have the current nesting capabilities of json, as well as the GIN/GIST indexing of hstore, so it will be fast

People working on postgresql 9.4 seem to be saying that the new, fast jsonb type will appeal to people who would have chosen to use a noSQL data store like MongoDB, but can now combine a relational database with query-able unstructured data under one roof

http://www.databasesoup.com/2014/02/why-hstore2jsonb-is-most-important.html

Benchmarks of postgresql 9.4 jsonb seem to be on par with or in some cases faster than MongoDB

They're all similar in that they're essentially zip files containing the actual file components. You can see the contents just by replacing the extension with .zip and opening them up. The difference with xlsb seems to be that the components are not XML-based but are in a binary format: supposedly this is beneficial when working with large files.

I have just been doing the exact same(ish) task of creating a batch script to run maven test scripts. The problem is that calling maven scrips with mvn clean install ... is itself a script and so needs to be done with call mvn clean install.

Code that will work

rem run a maven clean install
cd C:\rbe-ui-test-suite 
call mvn clean install
rem now run through all the test scripts
call mvn clean install -Prun-integration-tests -Dpattern=tc-login
call mvn clean install -Prun-integration-tests -Dpattern=login-1

Note rather the use of call. This will allow the use of consecutive maven scripts in the batch file.

Oh that's easy, just use extraData

You see the way extra data works behind the scenes is the FlatList or the VirtualisedList just checks wether that object has changed via a normal onComponentWillReceiveProps method.

So all you have to do is make sure you give something that changes to the extraData.

Here's what I do:

I'm using immutable.js so all I do is I pass a Map (immutable object) that contains whatever I want to watch.

<FlatList
    data={this.state.calendarMonths}
    extraData={Map({
        foo: this.props.foo,
        bar: this.props.bar
    })}
    renderItem={({ item })=>((
        <CustomComponentRow
            item={item}
            foo={this.props.foo}
            bar={this.props.bar}
        />
    ))}
/>

In that way, when this.props.foo or this.props.bar change, our CustomComponentRow will update, because the immutable object will be a different one than the previous.

You can stop the 2-line separation in the output by using

    with open('t.ini') as f:
       for line in f:
           print line.strip()
           if 'str' in line:
              break
