Spring cron expression for every day 1:01:am

@Scheduled(cron = "0 1 1 ? * *")

for more information check this information:

https://docs.oracle.com/cd/E12058_01/doc/doc.1014/e12030/cron_expressions.htm

Please read the other answers and comments, there’s a lot more information stated and nuances described (hash functions?) that I did not know when I answered this question.

According to Jenkins' own help (the "?" button) for the schedule task, 5 fields are specified:

This field follows the syntax of cron (with minor differences). Specifically, each line consists of 5 fields separated by TAB or whitespace: MINUTE HOUR DOM MONTH DOW

I just tried to get a job to launch at 4:42PM (my approximate local time) and it worked with the following, though it took about 30 extra seconds:

42 16 * * *

If you want multiple times, I think the following should work:

0 16,18,20,22 * * *

for 4, 6, 8, and 10 o'clock PM every day.

string connString = ConfigurationManager.ConnectionStrings["ConStringName"].ToString();

Remember don't Use ConnectionStrings[index] because you might of Global machine Config and Portability

You are parsing wrong parameter combination.here you passing @TaskName = and @ID instead of @TaskName = .SP need only one parameter.

I was facing the same issue then i made my key 16 byte and it's working properly now. Create your key exactly 16 byte. It will surely work.

$(document).ready(function(){
    $("#form_id").submit(function(){
        return condition;
    });
});

If you are facing this problem then put this key into your developer.facebook.com:

Then make sure your app is live on developer.facebook.com.

This green circle is indicating the app is live:

If it is not then follow these two steps for make your app live:

Step 1 Go to your application→setting→ add Contact Email and apply Save Changes.

Step 2 Go to the App Review option and make sure this toggle is Yes. I added a screenshot:

Note: If you want to copy the hashkey, check the BlueServiceQueue in LogCat.

Here is pro example of using multi proptypes and single proptype.

import React, { Component } from 'react';
import { string, shape, array, oneOfType } from 'prop-types';

class MyComponent extends Component {
  /**
   * Render
   */
  render() {
    const { title, data } = this.props;

    return (
      <>
        {title}
        <br />
        {data}
      </>
    );
  }
}

/**
 * Define component props
 */
MyComponent.propTypes = {
  data: oneOfType([array, string, shape({})]),
  title: string,
};

export default MyComponent;

Another case where NullReferenceExceptions can happen is the (incorrect) use of the as operator:

class Book {
    public string Name { get; set; }
}
class Car { }

Car mycar = new Car();
Book mybook = mycar as Book;   // Incompatible conversion --> mybook = null

Console.WriteLine(mybook.Name);   // NullReferenceException

Here, Book and Car are incompatible types; a Car cannot be converted/cast to a Book. When this cast fails, as returns null. Using mybook after this causes a NullReferenceException.

In general, you should use a cast or as, as follows:

If you are expecting the type conversion to always succeed (ie. you know what the object should be ahead of time), then you should use a cast:

ComicBook cb = (ComicBook)specificBook;

If you are unsure of the type, but you want to try to use it as a specific type, then use as:

ComicBook cb = specificBook as ComicBook;
if (cb != null) {
   // ...
}

If you put an asterisk in for build and revision visual studio uses the number of days since Jan. 1st 2000 as the build number, and the number of seconds since midnight divided by 2 as the revision.

A MUCH better life saver solution is http://autobuildversion.codeplex.com/

It works like a charm and it's VERY flexible.

Presuming every new branch in your tree is a div, I have implemented this solution with 2 functions:

function fillArray(vector1,vector2){
    for (var i = 0; i < vector1.length; i++){
        if (vector1[i].id.indexOf('q17_') == 0)
            vector2.push(vector1[i]);
        if(vector1[i].tagName == 'DIV')
            fillArray (document.getElementById(vector1[i].id).children,vector2);
    }
}

function selectAllElementsInsideDiv(divId){ 
    var matches = new Array();
    var searchEles = document.getElementById(divId).children;
    fillArray(searchEles,matches);
    return matches;
}

Now presuming your div's id is 'myDiv', all you have to do is create an array element and set its value to the function's return:

var ElementsInsideMyDiv = new Array();
ElementsInsideMyDiv =  selectAllElementsInsideDiv('myDiv')

I have tested it and it worked for me. I hope it helps you.

I've seen it used as a slight performance hack for a "dynamic type" pointer (in the section "Under the Hood"):

But here is the tricky trick I used to get fast performance for small types: if the value being held can fit inside of a void*, I don't actually bother allocating a new object, I force it into the pointer itself using placement new.

Determine if 2 lists have the same elements, regardless of order?

Inferring from your example:

x = ['a', 'b']
y = ['b', 'a']

that the elements of the lists won't be repeated (they are unique) as well as hashable (which strings and other certain immutable python objects are), the most direct and computationally efficient answer uses Python's builtin sets, (which are semantically like mathematical sets you may have learned about in school).

set(x) == set(y) # prefer this if elements are hashable

In the case that the elements are hashable, but non-unique, the collections.Counter also works semantically as a multiset, but it is far slower:

from collections import Counter
Counter(x) == Counter(y)

Prefer to use sorted:

sorted(x) == sorted(y) 

if the elements are orderable. This would account for non-unique or non-hashable circumstances, but this could be much slower than using sets.

Empirical Experiment

An empirical experiment concludes that one should prefer set, then sorted. Only opt for Counter if you need other things like counts or further usage as a multiset.

First setup:

import timeit
import random
from collections import Counter

data = [str(random.randint(0, 100000)) for i in xrange(100)]
data2 = data[:]     # copy the list into a new one

def sets_equal(): 
    return set(data) == set(data2)

def counters_equal(): 
    return Counter(data) == Counter(data2)

def sorted_lists_equal(): 
    return sorted(data) == sorted(data2)

And testing:

>>> min(timeit.repeat(sets_equal))
13.976069927215576
>>> min(timeit.repeat(counters_equal))
73.17287588119507
>>> min(timeit.repeat(sorted_lists_equal))
36.177085876464844

So we see that comparing sets is the fastest solution, and comparing sorted lists is second fastest.

Most of the solutions here don't take into account any kind of responsive text box.

The amount of text on the last line of the paragraph is dictated by the size of the viewers browser, and so it becomes very difficult.

I think in short, if you want any kind of browser/mobile responsiveness, this isn't possible :(

Building on @yunzen's great answer:

I'm guessing many people searching for this topic are trying use a large image as a "hero" background image, for example on a homepage. In this case, they would often want text to appear over the image and to have it scale down well on mobile devices.

Here is the perfect CSS for such a background image (use it on the <img> tag):

/* Set left edge of inner element to 50% of the parent element */
margin-left: 50%;

/* Move to the left by 50% of own width */
transform: translateX(-50%);

/* Scale image...(101% - instead of 100% - avoids possible 1px white border on left of image due to rounding error */
width: 101%;

/* ...but don't scale it too small on mobile devices - adjust this as needed */
min-width: 1086px;

/* allow content below image to appear on top of image */
position: absolute;
z-index: -1;

/* OPTIONAL - try with/without based on your needs */
top: 0;

/* OPTIONAL - use if your outer element containing the img has "text-align: center" */
left: 0;

I am using MVC4, I used following approach to redirect a custom html screen upon authorization breach.

Extend AuthorizeAttribute say CutomAuthorizer override the OnAuthorization and HandleUnauthorizedRequest

Register the CustomAuthorizer in the RegisterGlobalFilters.

public static void RegisterGlobalFilters(GlobalFilterCollection filters)
{

    filters.Add(new CustomAuthorizer());
}

upon identifying the unAuthorized access call HandleUnauthorizedRequestand redirect to the concerned controller action as shown below.

public class CustomAuthorizer : AuthorizeAttribute
{

    public override void OnAuthorization(AuthorizationContext filterContext)
    {
        bool isAuthorized = IsAuthorized(filterContext); // check authorization
        base.OnAuthorization(filterContext);
        if (!isAuthorized && !filterContext.ActionDescriptor.ActionName.Equals("Unauthorized", StringComparison.InvariantCultureIgnoreCase)
            && !filterContext.ActionDescriptor.ControllerDescriptor.ControllerName.Equals("LogOn", StringComparison.InvariantCultureIgnoreCase))
        {

            HandleUnauthorizedRequest(filterContext);

        }
    }

    protected override void HandleUnauthorizedRequest(AuthorizationContext filterContext)
    {
        filterContext.Result =
       new RedirectToRouteResult(
           new RouteValueDictionary{{ "controller", "LogOn" },
                                          { "action", "Unauthorized" }

                                         });

    }
}

I don't believe that you can achieve this functionality with standard <select> element.

What i would suggest is to use such way.

http://filamentgroup.com/lab/jquery_ipod_style_and_flyout_menus/

The basic version of it won't take too much space and you can easily bind mouseover events to sub items to show a nice tooltip.

Hope this helps, Sinan.

you can change your interface with code given below, if you need json String response..

@FormUrlEncoded
@POST("/api/level")
Call<JsonObject> checkLevel(@Field("id") int id);  

and retrofit function with this

Call<JsonObject> call = api.checkLevel(1);
    call.enqueue(new Callback<JsonObject>() {
        @Override
        public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
            Log.d("res", response.body().toString());
        }

        @Override
        public void onFailure(Call<JsonObject> call, Throwable t) {
            Log.d("error",t.getMessage());
        }
    });

First you need to publish the file by:

1. BUILD -> PUBLISH or by right clicking project on Solution Explorer -> properties -> publish or select project in Solution Explorer and press Alt + Enter NOTE: if you are using Visual Studio 2013 then in properties you have to go to BUILD and then you have to disable define DEBUG constant and define TRACE constant and you are ready to go.

2. Save your file to a particular folder. Find the produced files (the EXE file and the .config, .manifest, and .application files, along with any DLL files, etc.) - they are all in the same folder and typically in the bin\Debug folder below the project file (.csproj). In Visual Studio they are in the Application Files folder and inside that you just need the .exe and dll files. (You have to delete ClickOnce and other files and then make this folder a zip file and distribute it.)

NOTE: The ClickOnce application does install the project to system, but it has one advantage. You DO NOT require administrative privileges here to run (if your application follows the normal guidelines for which folders to use for application data, etc.).

First off, in order to have any image "resize" to fit a picturebox, you can set the PictureBox.SizeMode = PictureBoxSizeMode.StretchImage

If you want to do clipping of the image beforehand (i.e. cut off sides or top and bottom), then you need to clearly define what behavior you want (start at top, fill the height of the pciturebox and crop the rest, or start at the bottom, fill the height of the picturebox to the top, etc), and it should be fairly simple to use the Height / Width properties of both the picturebox and the image to clip the image and get the effect you are looking for.

If you don't care too much about performance and want to use the straightforward way, you can use either DIV or IDIV.

DIV or IDIV takes only one operand where it divides a certain register with this operand, the operand can be register or memory location only.

When operand is a byte: AL = AL / operand, AH = remainder (modulus).

Ex:

MOV AL,31h ; Al = 31h

DIV BL ; Al (quotient)= 08h, Ah(remainder)= 01h

when operand is a word: AX = (AX) / operand, DX = remainder (modulus).

Ex:

MOV AX,9031h ; Ax = 9031h

DIV BX ; Ax=1808h & Dx(remainder)= 01h

Although Reed Copsey and Marc Gravell already described about IQueryable (and also IEnumerable) enough,mI want to add little more here by providing a small example on IQueryable and IEnumerable as many users asked for it

Example: I have created two table in database

   CREATE TABLE [dbo].[Employee]([PersonId] [int] NOT NULL PRIMARY KEY,[Gender] [nchar](1) NOT NULL)
   CREATE TABLE [dbo].[Person]([PersonId] [int] NOT NULL PRIMARY KEY,[FirstName] [nvarchar](50) NOT NULL,[LastName] [nvarchar](50) NOT NULL)

The Primary key(PersonId) of table Employee is also a forgein key(personid) of table Person

Next i added ado.net entity model in my application and create below service class on that

public class SomeServiceClass
{   
    public IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable(IEnumerable<int> employeesToCollect)
    {
        DemoIQueryableEntities db = new DemoIQueryableEntities();
        var allDetails = from Employee e in db.Employees
                         join Person p in db.People on e.PersonId equals p.PersonId
                         where employeesToCollect.Contains(e.PersonId)
                         select e;
        return allDetails;
    }

    public IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable(IEnumerable<int> employeesToCollect)
    {
        DemoIQueryableEntities db = new DemoIQueryableEntities();
        var allDetails = from Employee e in db.Employees
                         join Person p in db.People on e.PersonId equals p.PersonId
                         where employeesToCollect.Contains(e.PersonId)
                         select e;
        return allDetails;
    }
}

they contains same linq. It called in program.cs as defined below

class Program
{
    static void Main(string[] args)
    {
        SomeServiceClass s= new SomeServiceClass(); 

        var employeesToCollect= new []{0,1,2,3};

        //IQueryable execution part
        var IQueryableList = s.GetEmployeeAndPersonDetailIQueryable(employeesToCollect).Where(i => i.Gender=="M");            
        foreach (var emp in IQueryableList)
        {
            System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
        }
        System.Console.WriteLine("IQueryable contain {0} row in result set", IQueryableList.Count());

        //IEnumerable execution part
        var IEnumerableList = s.GetEmployeeAndPersonDetailIEnumerable(employeesToCollect).Where(i => i.Gender == "M");
        foreach (var emp in IEnumerableList)
        {
           System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
        }
        System.Console.WriteLine("IEnumerable contain {0} row in result set", IEnumerableList.Count());

        Console.ReadKey();
    }
}

The output is same for both obviously

ID:1, EName:Ken,Gender:M  
ID:3, EName:Roberto,Gender:M  
IQueryable contain 2 row in result set  
ID:1, EName:Ken,Gender:M  
ID:3, EName:Roberto,Gender:M  
IEnumerable contain 2 row in result set

So the question is what/where is the difference? It does not seem to have any difference right? Really!!

Let's have a look on sql queries generated and executed by entity framwork 5 during these period

IQueryable execution part

--IQueryableQuery1 
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])

--IQueryableQuery2
SELECT 
[GroupBy1].[A1] AS [C1]
FROM ( SELECT 
    COUNT(1) AS [A1]
    FROM [dbo].[Employee] AS [Extent1]
    WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])
)  AS [GroupBy1]

IEnumerable execution part

--IEnumerableQuery1
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)

--IEnumerableQuery2
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)

Common script for both execution part

/* these two query will execute for both IQueryable or IEnumerable to get details from Person table
   Ignore these two queries here because it has nothing to do with IQueryable vs IEnumerable
--ICommonQuery1 
exec sp_executesql N'SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[FirstName] AS [FirstName], 
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=1

--ICommonQuery2
exec sp_executesql N'SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[FirstName] AS [FirstName], 
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=3
*/

So you have few questions now, let me guess those and try to answer them

Why are different scripts generated for same result?

Lets find out some points here,

all queries has one common part

WHERE [Extent1].[PersonId] IN (0,1,2,3)

why? Because both function IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable and IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable of SomeServiceClass contains one common line in linq queries

where employeesToCollect.Contains(e.PersonId)

Than why is the AND (N'M' = [Extent1].[Gender]) part is missing in IEnumerable execution part, while in both function calling we used Where(i => i.Gender == "M") inprogram.cs`

Now we are in the point where difference came between IQueryable and IEnumerable

What entity framwork does when an IQueryable method called, it tooks linq statement written inside the method and try to find out if more linq expressions are defined on the resultset, it then gathers all linq queries defined until the result need to fetch and constructs more appropriate sql query to execute.

It provide a lots of benefits like,

• only those rows populated by sql server which could be valid by the whole linq query execution
• helps sql server performance by not selecting unnecessary rows
• network cost get reduce

like here in example sql server returned to application only two rows after IQueryable execution` but returned THREE rows for IEnumerable query why?

In case of IEnumerable method, entity framework took linq statement written inside the method and constructs sql query when result need to fetch. it does not include rest linq part to constructs the sql query. Like here no filtering is done in sql server on column gender.

But the outputs are same? Because 'IEnumerable filters the result further in application level after retrieving result from sql server

SO, what should someone choose? I personally prefer to define function result as IQueryable<T> because there are lots of benefit it has over IEnumerable like, you could join two or more IQueryable functions, which generate more specific script to sql server.

Here in example you can see an IQueryable Query(IQueryableQuery2) generates a more specific script than IEnumerable query(IEnumerableQuery2) which is much more acceptable in my point of view.

This answer builds on bsap's answer using Exif-JS , but doesn't rely on jQuery and is fairly compatible even with older browsers. The following are example html and js files:

Some additions to a given set of answers:

First of all if you going to use Redis hash efficiently you must know a keys count max number and values max size - otherwise if they break out hash-max-ziplist-value or hash-max-ziplist-entries Redis will convert it to practically usual key/value pairs under a hood. ( see hash-max-ziplist-value, hash-max-ziplist-entries ) And breaking under a hood from a hash options IS REALLY BAD, because each usual key/value pair inside Redis use +90 bytes per pair.

It means that if you start with option two and accidentally break out of max-hash-ziplist-value you will get +90 bytes per EACH ATTRIBUTE you have inside user model! ( actually not the +90 but +70 see console output below )

For TheHippo answer, comments on Option one are misleading:

hgetall/hmset/hmget to the rescue if you need all fields or multiple get/set operation.

For BMiner answer.

Third option is actually really fun, for dataset with max(id) < has-max-ziplist-value this solution has O(N) complexity, because, surprise, Reddis store small hashes as array-like container of length/key/value objects!

But many times hashes contain just a few fields. When hashes are small we can instead just encode them in an O(N) data structure, like a linear array with length-prefixed key value pairs. Since we do this only when N is small, the amortized time for HGET and HSET commands is still O(1): the hash will be converted into a real hash table as soon as the number of elements it contains will grow too much

But you should not worry, you'll break hash-max-ziplist-entries very fast and there you go you are now actually at solution number 1.

Second option will most likely go to the fourth solution under a hood because as question states:

Keep in mind that if I use a hash, the value length isn't predictable. They're not all short such as the bio example above.

And as you already said: the fourth solution is the most expensive +70 byte per each attribute for sure.

My suggestion how to optimize such dataset:

You've got two options:

1. If you cannot guarantee max size of some user attributes than you go for first solution and if memory matter is crucial than compress user json before store in redis.

2. If you can force max size of all attributes. Than you can set hash-max-ziplist-entries/value and use hashes either as one hash per user representation OR as hash memory optimization from this topic of a Redis guide: https://redis.io/topics/memory-optimization and store user as json string. Either way you may also compress long user attributes.

Here's where it gets confusing, the text states "If the balance factor of R is 1, it means the insertion occurred on the (external) right side of that node and a left rotation is needed". But from m understanding the text said (as I quoted) that if the balance factor was within [-1, 1] then there was no need for balancing?

R is the right-hand child of the current node N.

If balance(N) = +2, then you need a rotation of some sort. But which rotation to use? Well, it depends on balance(R): if balance(R) = +1 then you need a left-rotation on N; but if balance(R) = -1 then you will need a double-rotation of some sort.

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

You were almost there.

Remove protected $dates = ['license_expire']

and then change your LicenseExpire accessor to:

public function getLicenseExpireAttribute($date)
{
    return Carbon::parse($date);
}

This way it will return a Carbon instance no matter what. So for your form you would just have $employee->license_expire->format('Y-m-d') (or whatever format is required) and diffForHumans() should work on your home page as well.

Hope this helps!

Try this.

declare @topval int

set @topval = 5 (customized value)

SELECT TOP(@topval) * from your_database

At a minimum, change this:

function BlockID() {
    var IDs = new Array();
        images['s'] = "Images/Block_01.png";
        images['g'] = "Images/Block_02.png";
        images['C'] = "Images/Block_03.png";
        images['d'] = "Images/Block_04.png";
    return IDs;
}

To this:

function BlockID() {
    var IDs = new Object();
        IDs['s'] = "Images/Block_01.png";
        IDs['g'] = "Images/Block_02.png";
        IDs['C'] = "Images/Block_03.png";
        IDs['d'] = "Images/Block_04.png";
    return IDs;
}

There are a couple fixes to point out. First, images is not defined in your original function, so assigning property values to it will throw an error. We correct that by changing images to IDs. Second, you want to return an Object, not an Array. An object can be assigned property values akin to an associative array or hash -- an array cannot. So we change the declaration of var IDs = new Array(); to var IDs = new Object();.

After those changes your code will run fine, but it can be simplified further. You can use shorthand notation (i.e., object literal property value shorthand) to create the object and return it immediately:

function BlockID() {
    return {
            "s":"Images/Block_01.png"
            ,"g":"Images/Block_02.png"
            ,"C":"Images/Block_03.png"
            ,"d":"Images/Block_04.png"
    };
}

In short, on MariaDB

1) sudo mysql -u root;
2) use mysql;
3) UPDATE mysql.user SET plugin = 'mysql_native_password', 
      Password = PASSWORD('pass1234') WHERE User = 'root';
4) FLUSH PRIVILEGES;
5) exit;

EDIT Until such time as StackOverflow allows us to version our answers, this is an answer that works for Android 3 and below. Please don't downvote it because it's not working for you now, because it definitely works with older Android versions.

You should only need to add one line to your onCreateDialog() method:

@Override
protected Dialog onCreateDialog(int id) {
    //all other dialog stuff (which dialog to display)

    //this line is what you need:
    dialog.getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN);

    return dialog;
}

This error arises when you don't use brackets with pop operation. Write the code in this manner.

listb.pop(0)

This is a valid python expression.

2019 update: Reporting validation errors is now made easier than a the time of the accepted answer by the use of HTMLFormElement.reportValidity() which not only checks validity like checkValidity() but also reports validation errors to the user.

The HTMLFormElement.reportValidity() method returns true if the element's child controls satisfy their validation constraints. When false is returned, cancelable invalid events are fired for each invalid child and validation problems are reported to the user.

Updated solution snippet:

function submitform() {
  var f = document.getElementsByTagName('form')[0];
  if(f.reportValidity()) {
    f.submit();
  }
}

• For a block of code, {}: = + %

• For a selected line: Shift + v select using the up/down arrow keys, and then press =.

• For the entire file: gg + = + G

Note: 'gg' means go to line 1, '=' is the indent command, and 'G' moves the cursor to the end of file.

If you want the original URL just use the method as described by jthalborn. If you want to rebuild the url do like David Levesque explained, here is a code snippet for it:

final javax.servlet.http.HttpServletRequest req = (javax.servlet.http.HttpServletRequest) ...;
final int serverPort = req.getServerPort();
if ((serverPort == 80) || (serverPort == 443)) {
  // No need to add the server port for standard HTTP and HTTPS ports, the scheme will help determine it.
  url = String.format("%s://%s/...", req.getScheme(), req.getServerName(), ...);
} else {
  url = String.format("%s://%s:%s...", req.getScheme(), req.getServerName(), serverPort, ...);
}

You still need to consider the case of a reverse-proxy:

• request.getScheme() is returning http instead of returning https in java

Could use constants for the ports but not sure if there is a reliable source for them, default ports:

• Are HTTP and HTTPS default port numbers defined in the JDK?

Most developers will know about port 80 and 443 anyways, so constants are not that helpful.

Also see this similar post.

You can call setScale(newScale, roundingMode) method three times with changing the newScale value from 4 to 3 to 2 like

First case

    BigDecimal a = new BigDecimal("10.12345");

    a = a.setScale(4, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.1235
    a = a.setScale(3, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.124
    a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println("" + a); //10.12

Second case

    BigDecimal a = new BigDecimal("10.12556");

    a = a.setScale(4, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.1256
    a = a.setScale(3, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.126
    a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println("" + a); //10.13

Use ascii_bin where ever possible, it will match up with almost any collation. A username seldom accepts special characters anyway.

If you like to do this for open files on Notepad++, you can use Combine plugin: http://www.scout-soft.com/combine/

You can do it as below.

$(this).prev('input').val("hello world");

Alternate solution

Create a column that will store the month:

data['month'] = data['date'].dt.month

Create a column that will store the year:

data['year'] = data['date'].dt.year

port number 3306 is used for MySQL and tomcat using 8080 port.more port numbers are available for run the servers or software whatever may be for our instant compilation..8080 is default for number so only we are getting port error in eclipse IDE. jvm and tomcat always prefer the 8080.3306 is default port number for MySQL.So only do not want to mention every time as "localhost:3306"

  <?php  
    $dbhost = 'localhost:3306';
//3306 default port number $dbhost='localhost'; is enough to specify the port number
//when we are utilizing xammp default port number is 8080.
      $dbuser = 'root';
      $dbpass = '';
         $db='users';

             $conn = mysqli_connect($dbhost, $dbuser, $dbpass,$db) or die ("could not connect to mysql");      

              // mysqli_select_db("users") or die ("no database");  

    if(! $conn ) {
        die('Could not connect: ' . mysqli_error($conn));
    }else{
        echo 'Connected successfully';
    }
    ?>

Or alternatively, you could use this:

WHERE CHARINDEX(N'Apples', someColumn) = 0

Not sure which one performs better - you gotta test it! :-)

Marc

UPDATE: the performance seems to be pretty much on a par with the other solution (WHERE someColumn NOT LIKE '%Apples%') - so it's really just a question of your personal preference.

If the view is accessed via a stored procedure, the execute grant is insufficient to access the view. You must grant select explicitly.

simply type this

grant all on to public;

Try using:

git checkout branchName -- fileName

Ex:

git checkout master -- index.php

You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

\begin{table}

  -- cut --

You're looking for child_process

var exec = require('child_process').exec;
var child;

child = exec(command,
   function (error, stdout, stderr) {
      console.log('stdout: ' + stdout);
      console.log('stderr: ' + stderr);
      if (error !== null) {
          console.log('exec error: ' + error);
      }
   });

As pointed out by Renato, there are some synchronous exec packages out there now too, see sync-exec that might be more what yo're looking for. Keep in mind though, node.js is designed to be a single threaded high performance network server, so if that's what you're looking to use it for, stay away from sync-exec kinda stuff unless you're only using it during startup or something.

Like this:

keys = ['a', 'b', 'c']
values = [1, 2, 3]
dictionary = dict(zip(keys, values))
print(dictionary) # {'a': 1, 'b': 2, 'c': 3}

Voila :-) The pairwise dict constructor and zip function are awesomely useful.

I guess this is what you want, it does exactly what you specified.

#include<stdio.h>
#include<stdlib.h>

int main(int argc, char** argv) {
    int age;
    char* buffer;
    buffer = malloc(200 * sizeof(char));
    sscanf("19 cool kid", "%d cool %s", &age, buffer);
    printf("cool %s is %d years old\n", buffer, age);
    return 0;
}

The format expects: first a number (and puts it at where &age points to), then whitespace (zero or more), then the literal string "cool", then whitespace (zero or more) again, and then finally a string (and put that at whatever buffer points to). You forgot the "cool" part in your format string, so the format then just assumes that is the string you were wanting to assign to buffer. But you don't want to assign that string, only skip it.

Alternative, you could also have a format string like: "%d %s %s", but then you must assign another buffer for it (with a different name), and print it as: "%s %s is %d years old\n".

Reinstall java and choose a destination folder without a space

The standard Sun JDK for linux has an absolutely ok cacerts and overall all files in the specified directory. The problem is the installation you use.

Sub Results2()

    Dim rCell As Range
    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim lCnt As Long

    Set shSource = ThisWorkbook.Sheets("Sheet1")
    Set shDest = ThisWorkbook.Sheets("Sheet2")

    For Each rCell In shSource.Range("A1", shSource.Cells(shSource.Rows.Count, 1).End(xlUp)).Cells
        lCnt = lCnt + 1
        shDest.Range("A4").Offset(0, lCnt * 4).Formula = "=" & rCell.Address(False, False, , True) & "+" & rCell.Offset(0, 1).Address(False, False, , True)
    Next rCell

End Sub

This loops through column A of sheet1 and creates a formula in sheet2 for every cell. To find the last cell in Sheet1, I start at the bottom (shSource.Rows.Count) and .End(xlUp) to get the last cell in the column that's not blank.

To create the elements of the formula, I use the Address property of the cell on Sheet. I'm using three of the arguments to Address. The first two are RowAbsolute and ColumnAbsolute, both set to false. I don't care about the third argument, but I set the fourth argument (External) to True so that it includes the sheet name.

I prefer to go from Source to Destination rather than the other way. But that's just a personal preference. If you want to work from the destination,

Sub Results3()

    Dim i As Long, lCnt As Long
    Dim sh As Worksheet

    lCnt = Application.WorksheetFunction.CountA(ThisWorkbook.Sheets("Sheet1").Columns(1))
    Set sh = ThisWorkbook.Sheets("Sheet2")

    Const sSOURCE As String = "Sheet1!"

    For i = 1 To lCnt
        sh.Range("A1").Offset(0, 4 * (i - 1)).Formula = "=" & sSOURCE & "A" & i & " + " & sSOURCE & "B" & i
    Next i

End Sub

For loading weights, you need to have a model first. It must be:

existingModel.save_weights('weightsfile.h5')
existingModel.load_weights('weightsfile.h5')     

If you want to save and load the entire model (this includes the model's configuration, it's weights and the optimizer states for further training):

model.save_model('filename')
model = load_model('filename')

If you are using Hg Tortoise just activate the extension "strip" in:

1. File/Settings/Extensions/
2. Select strip

Then select the bottom revision from where you want to start striping, by doing right click on it, and selecting:

1. Modify history
2. Strip

Just like this:

In this example it will erase from the 19th revision to the last one commited(22).

For those who could not get DATEADD to work, try this instead: ( NOW( ) - INTERVAL 1 MONTH )

You'll need to use fs for that: http://nodejs.org/api/fs.html

And in particular the fs.rename() function:

var fs = require('fs');
fs.rename('/path/to/Afghanistan.png', '/path/to/AF.png', function(err) {
    if ( err ) console.log('ERROR: ' + err);
});

Put that in a loop over your freshly-read JSON object's keys and values, and you've got a batch renaming script.

fs.readFile('/path/to/countries.json', function(error, data) {
    if (error) {
        console.log(error);
        return;
    }

    var obj = JSON.parse(data);
    for(var p in obj) {
        fs.rename('/path/to/' + obj[p] + '.png', '/path/to/' + p + '.png', function(err) {
            if ( err ) console.log('ERROR: ' + err);
        });
    }
});

(This assumes here that your .json file is trustworthy and that it's safe to use its keys and values directly in filenames. If that's not the case, be sure to escape those properly!)

From the answer here, spark.sql.shuffle.partitions configures the number of partitions that are used when shuffling data for joins or aggregations.

spark.default.parallelism is the default number of partitions in RDDs returned by transformations like join, reduceByKey, and parallelize when not set explicitly by the user. Note that spark.default.parallelism seems to only be working for raw RDD and is ignored when working with dataframes.

If the task you are performing is not a join or aggregation and you are working with dataframes then setting these will not have any effect. You could, however, set the number of partitions yourself by calling df.repartition(numOfPartitions) (don't forget to assign it to a new val) in your code.

To change the settings in your code you can simply do:

sqlContext.setConf("spark.sql.shuffle.partitions", "300")
sqlContext.setConf("spark.default.parallelism", "300")

Alternatively, you can make the change when submitting the job to a cluster with spark-submit:

./bin/spark-submit --conf spark.sql.shuffle.partitions=300 --conf spark.default.parallelism=300

To improve on @bgporter's answer, with Python-3 you will probably want to operate on bytes instead of needlessly converting things to utf-8:

>>> import shutil
>>> import sys
>>> with open("test.txt", "rb") as f:
...    shutil.copyfileobj(f, sys.stdout.buffer)

Thanks for the input. I'm obviously seeing some issues that aren't being replicated on others machines. Based on Jean's answer I have come up with less elegant solution that seems to work.

Since if I pass the cell a value directly from cdate, or just format it as a number it leaves the cell value as a string I've had to pass the date value into a numerical variable before passing that number back to the cell.

Function CellContentCanBeInterpretedAsADate(cell As Range) As Boolean
    Dim d As Date
    On Error Resume Next
    d = CDate(cell.Value)
    If Err.Number <> 0 Then
        CellContentCanBeInterpretedAsADate = False
    Else
        CellContentCanBeInterpretedAsADate = True
    End If
    On Error GoTo 0
End Function

Example usage:

Dim cell As Range
dim cvalue as double
Set cell = Range("A1")

If CellContentCanBeInterpretedAsADate(cell) Then
    cvalue = cdate(cell.value)
    cell.value = cvalue
    cell.NumberFormat = "mm/dd/yyyy hh:mm"
Else
    cell.NumberFormat = "General"
End If

You can also open a new tab calling to an action method with parameter like this:

   var reportDate = $("#inputDateId").val();
   var url = '@Url.Action("PrintIndex", "Callers", new {dateRequested = "findme"})';
   window.open(window.location.href = url.replace('findme', reportDate), '_blank');

To extend what Rahul Gupta said:

You can use Java function int random = Random.nextInt(n).
This returns a random int in the range [0, n-1].

I.e., to get the range [20, 80] use:

final int random = new Random().nextInt(61) + 20; // [0, 60] + 20 => [20, 80]

To generalize more:

final int min = 20;
final int max = 80;
final int random = new Random().nextInt((max - min) + 1) + min;

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.

It doesn't get easier than this. Sleep might be implemented in your FLTK or whatever, but this covers all the best ways to do standard sort of system sleeps without special event interrupts. Behold:

                  pol:types('struct', 'unsigned long', 'int')
                  os.sleep = function(sec)
                     pol(nil,0,sec*1000)
                  end
               end
            end
         elseif package.config:match("^\\") then
            -- print("busywait")
            -- if the computer is politically opposed to NIXon, we do the busywait
            -- and shake it all about
            os.sleep = function(sec)
               local timr = os.time()
               repeat until os.time() > timr + sec
            end
         else
            -- print("NIX")
            -- or we get NIXed
            os.sleep = function(sec)
               os.execute("sleep " .. sec)
            end
         end
      end
   end
end

In my case the problem was rendering the output.. So I used the default text if the ajax data is not present yet.

  templateSelection: function(data) {
    return data.name || data.element.innerText;
  }

It will just sleep the thread except in the case where your application has only a single thread, in which case it will sleep the thread and effectively the process as well.

The python documentation on sleep doesn't specify this however, so I can certainly understand the confusion!

A Virtual PC tries to emulate a Computer, from the point of view of a Programmer BUT, at the same time, it simulates a Computer from the point of view of a Electrical Engineer.

Use splatting.

__VA_ARGS__ is the standard way to do it. Don't use compiler-specific hacks if you don't have to.

I'm really annoyed that I can't comment on the original post. In any case, C++ is not a superset of C. It is really silly to compile your C code with a C++ compiler. Don't do what Donny Don't does.

If you happen to already be using pandas, you can save a little space by not specifying the format:

import pandas as pd
startdate = "10/10/2011"
enddate = pd.to_datetime(startdate) + pd.DateOffset(days=5)

For me in PgAdmin 4 on Mac OS High Sierra, Clicking the PostrgreSQL10 database under Servers in the left column, then the Properties tab, showed 5433 as the port under Connection. (I don't know why, because I chose 5432 during install). Anyway, I clicked the Edit icon under the Properties tab, change that to 5432, saved, and that solved the problem. Go figure.

In the spirit of being complete, the answers that instruct you to use Guid.NewGuid() are correct.

In addressing your subsequent edit, you'll need to post the code for your RequestObject class. I'm suspecting that your guid property is not marked as a DataMember, and thus is not being serialized over the wire. Since default(Guid) is the same as new Guid() (i.e. all 0's), this would explain the behavior you're seeing.

I was having a problem on Ubuntu 18.04 on Mysql. When I needed to create a new user, the policy was always high.

The way I figured out how to disable, for future colleagues who come to investigate, was set to low.

Login to the mysql server as root

mysql -h localhost -u root -p

Set the new type of validation

SET GLOBAL validate_password_policy=0; //For Low

Restart mysql

sudo service mysql restart

In docker-compose.yml you can use this format:

volumes:
    - host directory:container directory

according to their documentation

You might want to use verify() in combination with the ArgumentCaptor to assure execution in the test and the ArgumentCaptor to evaluate the arguments:

ArgumentCaptor<String> argument = ArgumentCaptor.forClass(String.class);
verify(mock).myFunction(argument.capture());
assertEquals("the expected value here", argument.getValue());

The argument's value is obviously accessible via the argument.getValue() for further manipulation / checking /whatever.

As Matt has said, use Console.Write. I would also recommend explicitly flushing the output, however - I believe WriteLine does this automatically, but I'd seen oddities when just using Console.Write and then waiting. So Matt's code becomes:

Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();

Phew, Django documentation really does not have good example about this. I spent over 2 hours to dig up all the pieces to understand how this works. With that knowledge I implemented a project that makes possible to upload files and show them as list. To download source for the project, visit https://github.com/axelpale/minimal-django-file-upload-example or clone it:

> git clone https://github.com/axelpale/minimal-django-file-upload-example.git

Update 2013-01-30: The source at GitHub has also implementation for Django 1.4 in addition to 1.3. Even though there is few changes the following tutorial is also useful for 1.4.

Update 2013-05-10: Implementation for Django 1.5 at GitHub. Minor changes in redirection in urls.py and usage of url template tag in list.html. Thanks to hubert3 for the effort.

Update 2013-12-07: Django 1.6 supported at GitHub. One import changed in myapp/urls.py. Thanks goes to Arthedian.

Update 2015-03-17: Django 1.7 supported at GitHub, thanks to aronysidoro.

Update 2015-09-04: Django 1.8 supported at GitHub, thanks to nerogit.

Update 2016-07-03: Django 1.9 supported at GitHub, thanks to daavve and nerogit

Project tree

A basic Django 1.3 project with single app and media/ directory for uploads.

                forms.py
                models.py
                urls.py
                views.py
            __init__.py
            manage.py
            settings.py
            urls.py

1. Settings: myproject/settings.py

To upload and serve files, you need to specify where Django stores uploaded files and from what URL Django serves them. MEDIA_ROOT and MEDIA_URL are in settings.py by default but they are empty. See the first lines in Django Managing Files for details. Remember also set the database and add myapp to INSTALLED_APPS

...
import os

BASE_DIR = os.path.dirname(os.path.dirname(__file__))
...
DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.sqlite3',
        'NAME': os.path.join(BASE_DIR, 'database.sqlite3'),
        'USER': '',
        'PASSWORD': '',
        'HOST': '',
        'PORT': '',
    }
}
...
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'
...
INSTALLED_APPS = (
    ...
    'myapp',
)

2. Model: myproject/myapp/models.py

Next you need a model with a FileField. This particular field stores files e.g. to media/documents/2011/12/24/ based on current date and MEDIA_ROOT. See FileField reference.

# -*- coding: utf-8 -*-
from django.db import models

class Document(models.Model):
    docfile = models.FileField(upload_to='documents/%Y/%m/%d')

3. Form: myproject/myapp/forms.py

To handle upload nicely, you need a form. This form has only one field but that is enough. See Form FileField reference for details.

# -*- coding: utf-8 -*-
from django import forms

class DocumentForm(forms.Form):
    docfile = forms.FileField(
        label='Select a file',
        help_text='max. 42 megabytes'
    )

4. View: myproject/myapp/views.py

A view where all the magic happens. Pay attention how request.FILES are handled. For me, it was really hard to spot the fact that request.FILES['docfile'] can be saved to models.FileField just like that. The model's save() handles the storing of the file to the filesystem automatically.

# -*- coding: utf-8 -*-
from django.shortcuts import render_to_response
from django.template import RequestContext
from django.http import HttpResponseRedirect
from django.core.urlresolvers import reverse

from myproject.myapp.models import Document
from myproject.myapp.forms import DocumentForm

def list(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])
            newdoc.save()

            # Redirect to the document list after POST
            return HttpResponseRedirect(reverse('myapp.views.list'))
    else:
        form = DocumentForm() # A empty, unbound form

    # Load documents for the list page
    documents = Document.objects.all()

    # Render list page with the documents and the form
    return render_to_response(
        'myapp/list.html',
        {'documents': documents, 'form': form},
        context_instance=RequestContext(request)
    )

5. Project URLs: myproject/urls.py

Django does not serve MEDIA_ROOT by default. That would be dangerous in production environment. But in development stage, we could cut short. Pay attention to the last line. That line enables Django to serve files from MEDIA_URL. This works only in developement stage.

See django.conf.urls.static.static reference for details. See also this discussion about serving media files.

# -*- coding: utf-8 -*-
from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = patterns('',
    (r'^', include('myapp.urls')),
) + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

6. App URLs: myproject/myapp/urls.py

To make the view accessible, you must specify urls for it. Nothing special here.

# -*- coding: utf-8 -*-
from django.conf.urls import patterns, url

urlpatterns = patterns('myapp.views',
    url(r'^list/$', 'list', name='list'),
)

7. Template: myproject/myapp/templates/myapp/list.html

The last part: template for the list and the upload form below it. The form must have enctype-attribute set to "multipart/form-data" and method set to "post" to make upload to Django possible. See File Uploads documentation for details.

The FileField has many attributes that can be used in templates. E.g. {{ document.docfile.url }} and {{ document.docfile.name }} as in the template. See more about these in Using files in models article and The File object documentation.

8. Initialize

Just run syncdb and runserver.

> cd myproject
> python manage.py syncdb
> python manage.py runserver

Results

Finally, everything is ready. On default Django developement environment the list of uploaded documents can be seen at localhost:8000/list/. Today the files are uploaded to /path/to/myproject/media/documents/2011/12/17/ and can be opened from the list.

I hope this answer will help someone as much as it would have helped me.

You can use

reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v ServiceName /d "c:\path\to\service\file\exe"

And it will appear int the service list. I do not know, whether that works correctly though. A service usually has to listen to several events.

There are several service wrapper though, that can run any application as a real service. For Example Microsofts SrvAny from the Win2003 Resource Kit

After Add this to your web.config file and configure according to your service name and contract name.

<behaviors>
   <serviceBehaviors>
      <behavior name="metadataBehavior">
         <serviceMetadata httpGetEnabled="true" />
      </behavior>
   </serviceBehaviors>
</behaviors>
<services>
   <service name="MyService.MyService" behaviorConfiguration="metadataBehavior">
      <endpoint 
          address=""   <!-- don't put anything here - Cassini will determine address -->
          binding="basicHttpBinding" 
          contract="MyService.IMyService"/>
      <endpoint 
          address="mex" 
          binding="mexHttpBinding" 
          contract="IMetadataExchange"/>
   </service>
</services>

Please add this in your Service.svc

using System.ServiceModel.Description;

Hope it will helps you.

In Xcode 8.0 you can simply do it by changing insets in size inspector.

Select the UIButton -> Attributes Inspector -> go to size inspector and modify the content, image and title insets.

And if you want to change image on right side you can simply change the semantic property to Force Right-to-left in Attribute inspector .

The upside-down A symbol is the universal quantifier from predicate logic. (Also see the more complete discussion of the first-order predicate calculus.) As others noted, it means that the stated assertions holds "for all instances" of the given variable (here, s). You'll soon run into its sibling, the backwards capital E, which is the existential quantifier, meaning "there exists at least one" of the given variable conforming to the related assertion.

If you're interested in logic, you might enjoy the book Logic and Databases: The Roots of Relational Theory by C.J. Date. There are several chapters covering these quantifiers and their logical implications. You don't have to be working with databases to benefit from this book's coverage of logic.

I have been looking at this. On populating the drop down anchors, I have given them a class and data attributes, so when needing to do an action you can do:

<li><a class="dropDownListItem" data-name="Fred Smith" href="#">Fred</a></li>

and then in the jQuery doing something like:

$('.dropDownListItem').click(function(e) {
    var name = e.currentTarget;
    console.log(name.getAttribute("data-name"));
});

So if you have dynamically generated list items in your dropdown and need to use the data that isn't just the text value of the item, you can use the data attributes when creating the dropdown listitem and then just give each item with the class the event, rather than referring to the id's of each item and generating a click event.

This problem is mainly in gradle or in misversioned libraries, including, from libraries, when both define the same class. Expand and check, imported external libraries...

You cannot have two same classes to be exported to one place, or code, therefore, dexer does not know which one should be used...

Only update your import.

import android.app.AlertDialog;

to

import android.support.v7.app.AlertDialog;

It will be fixed.

I use favicons-webpack-plugin

const FaviconsWebpackPlugin = require("favicons-webpack-plugin");

module.exports={
plugins:[
    new FaviconsWebpackPlugin("./public/favicon.ico"),
//public is in the root folder in this app. 

]
}

sp_describe_first_result_set

will help to identify the datatypes of query by analyzing datatypes of first resultset of query

https://docs.microsoft.com/en-us/sql/relational-databases/system-stored-procedures/sp-describe-first-result-set-transact-sql?view=sql-server-2017

The cleaner way in my opinion is to first export to .py as aforementioned:

pyuic4 foo.ui > foo.py

And then use it inside your code (e.g main.py), like:

from foo import Ui_MyWindow


class MyWindow(QtGui.QDialog):
    def __init__(self):
        super(MyWindow, self).__init__()

        self.ui = Ui_MyWindow()
        self.ui.setupUi(self)

        # go on setting up your handlers like:
        # self.ui.okButton.clicked.connect(function_name)
        # etc...

def main():
    app = QtGui.QApplication(sys.argv)
    w = MyWindow()
    w.show()
    sys.exit(app.exec_())

if __name__ == "__main__":
    main()

This way gives the ability to other people who don't use qt-designer to read the code, and also keeps your functionality code outside foo.py that could be overwritten by designer. You just reference ui through MyWindow class as seen above.

Using absolute as position is not responsive + mobile friendly. I would suggest using a div with a background-image and then placing text in the div will place text over the image. Depending on your html, you might need to use height with vh value

Based on acheron55 answer I posted a possible implementation here.
Here is a brief summery of it:

All you have to do, is to keep track of the path through which the target has been reached. A simple way to do it, is to push into the Queue the whole path used to reach a node, rather than the node itself.
The benefit of doing so is that when the target has been reached the queue holds the path used to reach it.
This is also applicable to cyclic graphs, where a node can have more than one parent.

Check out the excellent Cronical program at https://github.com/mgefvert/Cronical

It is a .NET program that reads a text file with unix-like cron lines. Very convenient to use. It will send emails if stdout just like unix cron. It even supports acting as the service runner.

I think this is also the answer that you need. In addition, Here I add the required attributes. onChange attributes of Each input components are functions. You need to add your own logic there.

handleEmailChange: function(e) {
    this.setState({email: e.target.value});
},
handlePasswordChange: function(e) {
   this.setState({password: e.target.value});
},
formSubmit : async function(e) {
    e.preventDefault();
    // Form submit Logic
  },
render : function() {
      return (
        <form onSubmit={(e) => this.formSubmit(e)}>
          <input type="text" name="email" placeholder="Email" value={this.state.email} onChange={this.handleEmailChange} required />
          <input type="password" name="password" placeholder="Password" value={this.state.password} onChange={this.handlePasswordChange} required />
          <button type="button">Login</button>
        </form>);
},
handleLogin: function() {
    //Login Function
}

Use Like This for HTML 4.01

Correct me if wrong...I think request does persist between consecutive pages..

Think you traverse from page 1--> page 2-->page 3.

You have some value set in the request object using setAttribute from page 1, which you retrieve in page 2 using getAttribute,then if you try setting something again in same request object to retrieve it in page 3 then it fails giving you null value as "the request that created the JSP, and the request that gets generated when the JSP is submitted are completely different requests and any attributes placed on the first one will not be available on the second".

I mean something like this in page 2 fails:

Where as the same thing has worked in case of page 1 like:

So I think I would need to proceed with either of the two options suggested by Phill.

You can use find

find . -type d > output.txt

or tree

tree -d > output.txt

tree, If not installed on your system.

If you are using ubuntu

sudo apt-get install tree

If you are using mac os.

brew install tree

In my case I signed with only V2 signature (from Android 7 onward) but tried to install on 5 and 6. Adding V1 during ARK generation/signing fixed the issue.

See Difference between signature versions - V1 (Jar Signature) and V2 (Full APK Signature) while generating a signed APK in Android Studio?.

I use for enter su mode in abd shell

adb shell "su"

var imgSrc, imgW, imgH;
function myFunction(image){
    var img = new Image();
    img.src = image;
    img.onload = function() {   
        return {
            src:image,
            width:this.width,
            height:this.height};
        }
    return img;
}
var x = myFunction('http://www.google.com/intl/en_ALL/images/logo.gif');
    //Waiting for the image loaded. Otherwise, system returned 0 as both width and height.
x.addEventListener('load',function(){
    imgSrc = x.src;
    imgW = x.width;
    imgH = x.height;
});
x.addEventListener('load',function(){
    console.log(imgW+'x'+imgH);//276x110
});
console.log(imgW);//undefined.
console.log(imgH);//undefined.
console.log(imgSrc);//undefined.

This is my method, hope this helpful. :)

I never had any luck with that approach. I always do this (hope this helps):

var obj = {};

obj.first_name = $("#namec").val();
obj.last_name = $("#surnamec").val();
obj.email = $("#emailc").val();
obj.mobile = $("#numberc").val();
obj.password = $("#passwordc").val();

Then in your ajax:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify(obj),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
    });

Allow an analysis.

#include <iostream>   // not #include "iostream"
using namespace std;  // in this case okay, but never do that in header files

class A
{
 public:
  void f() { cout<<"f()\n"; }
};

int main()
{
 /*
 // A a; //this works
 A *a = new A(); //this doesn't
 a.f(); // "f has not been declared"
 */ // below


 // system("pause");  <-- Don't do this. It is non-portable code. I guess your 
 //                       teacher told you this?
 //                       Better: In your IDE there is prolly an option somewhere
 //                               to not close the terminal/console-window.
 //                       If you compile on a CLI, it is not needed at all.
}

As a general advice:

0) Prefer automatic variables
  int a;
  MyClass myInstance;
  std::vector<int> myIntVector;

1) If you need data sharing on big objects down 
   the call hierarchy, prefer references:

  void foo (std::vector<int> const &input) {...}
  void bar () { 
       std::vector<int> something;
       ...
       foo (something);
  }


2) If you need data sharing up the call hierarchy, prefer smart-pointers
   that automatically manage deletion and reference counting.

3) If you need an array, use std::vector<> instead in most cases.
   std::vector<> is ought to be the one default container.

4) I've yet to find a good reason for blank pointers.

   -> Hard to get right exception safe

       class Foo {
           Foo () : a(new int[512]), b(new int[512]) {}
           ~Foo() {
               delete [] b;
               delete [] a;
           }
       };

       -> if the second new[] fails, Foo leaks memory, because the
          destructor is never called. Avoid this easily by using 
          one of the standard containers, like std::vector, or
          smart-pointers.

As a rule of thumb: If you need to manage memory on your own, there is generally a superiour manager or alternative available already, one that follows the RAII principle.

This does not answer the original question, but as the question is highly ranked and linked for any ContextClassLoader query, I think it is important to answer the related question of when the context class loader should be used. Short answer: never use the context class loader! But set it to getClass().getClassLoader() when you have to call a method that is missing a ClassLoader parameter.

When code from one class asks to load another class, the correct class loader to use is the same class loader as the caller class (i.e., getClass().getClassLoader()). This is the way things work 99.9% of the time because this is what the JVM does itself the first time you construct an instance of a new class, invoke a static method, or access a static field.

When you want to create a class using reflection (such as when deserializing or loading a configurable named class), the library that does the reflection should always ask the application which class loader to use, by receiving the ClassLoader as a parameter from the application. The application (which knows all the classes that need constructing) should pass it getClass().getClassLoader().

Any other way to obtain a class loader is incorrect. If a library uses hacks such as Thread.getContextClassLoader(), sun.misc.VM.latestUserDefinedLoader(), or sun.reflect.Reflection.getCallerClass() it is a bug caused by a deficiency in the API. Basically, Thread.getContextClassLoader() exists only because whoever designed the ObjectInputStream API forgot to accept the ClassLoader as a parameter, and this mistake has haunted the Java community to this day.

That said, many many JDK classes use one of a few hacks to guess some class loader to use. Some use the ContextClassLoader (which fails when you run different apps on a shared thread pool, or when you leave the ContextClassLoader null), some walk the stack (which fails when the direct caller of the class is itself a library), some use the system class loader (which is fine, as long as it is documented to only use classes in the CLASSPATH) or bootstrap class loader, and some use an unpredictable combination of the above techniques (which only makes things more confusing). This has resulted in much weeping and gnashing of teeth.

When using such an API, first, try to find an overload of the method that accepts the class loader as a parameter. If there is no sensible method, then try setting the ContextClassLoader before the API call (and resetting it afterwards):

ClassLoader originalClassLoader = Thread.currentThread().getContextClassLoader();
try {
    Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
    // call some API that uses reflection without taking ClassLoader param
} finally {
    Thread.currentThread().setContextClassLoader(originalClassLoader);
}

To delete rows from a table, you need to provide selection criteria that identify the rows to the delete() method. The mechanism works the same as the selection arguments to the query() method. It divides the selection specification into a selection clause(where clause) and selection arguments.

    SQLiteDatabase db  = this.getWritableDatabase();
     // Define 'where' part of query.
    String selection = Contract.COLUMN_COMPANY_ID + " =?  and "
                       + Contract.CLOUMN_TYPE +" =? ";
   // Specify arguments in placeholder order.
    String[] selectionArgs = { cid,mode };
    // Issue SQL statement.
    int deletedRows = db.delete(Contract.TABLE_NAME, 
                       selection, selectionArgs);
    return deletedRows;// no.of rows deleted.

The return value for the delete() method indicates the number of rows that were deleted from the database.

First check your listener is on or off. Go to net manager then Local -> service naming -> orcl. Then change your HOST NAME and put your PC name. Now go to LISTENER and change the HOST and put your PC name.

I just ran into the same problem. As implicitly stated inside the .zshrc-file (in your user-root-folder), you need to migrate the pathes you've already inserted in your .bash_profile, bashrc or so to resolve this.

Copying all additional pathes from .bash_profile to .zshrc fixed it for me, cause zsh now knows where to look.

#add path to Anaconda-bin
export PATH="/Users/YOURUSERNAME!!/anaconda3/bin:$PATH"

 #N.B. for miniconda use
export PATH="/Users/YOURUSERNAME!!!/miniconda3/bin:$PATH"

Depending on where you installed anaconda this path might be different.

You're trying to put a text node inside an input element.

Input elements are empty and can't have children.

...
var checkbox = document.createElement('input');
checkbox.type = "checkbox";
checkbox.name = "name";
checkbox.value = "value";
checkbox.id = "id";

var label = document.createElement('label')
label.htmlFor = "id";
label.appendChild(document.createTextNode('text for label after checkbox'));

container.appendChild(checkbox);
container.appendChild(label);

Since the question on how to set fields mandatory pops up under each post, I wrote a small example on how to set fields as required:

public class ExampleDTO {
    @NotNull
    private String mandatoryParam;

    private String optionalParam;
    
    @DateTimeFormat(iso = ISO.DATE) //accept Dates only in YYYY-MM-DD
    @NotNull
    private LocalDate testDate;

    public String getMandatoryParam() {
        return mandatoryParam;
    }
    public void setMandatoryParam(String mandatoryParam) {
        this.mandatoryParam = mandatoryParam;
    }
    public String getOptionalParam() {
        return optionalParam;
    }
    public void setOptionalParam(String optionalParam) {
        this.optionalParam = optionalParam;
    }
    public LocalDate getTestDate() {
        return testDate;
    }
    public void setTestDate(LocalDate testDate) {
        this.testDate = testDate;
    }
}

//Add this to your rest controller class
@RequestMapping(value = "/test", method = RequestMethod.GET)
public String testComplexObject (@Valid ExampleDTO e){
    System.out.println(e.getMandatoryParam() + " " + e.getTestDate());
    return "Does this work?";
}

Learning higher math, for most programmers, is important simply because it bends your brain to think logically, in a step-by-step manner to get from one thing to another.

Very few programming jobs, though, require anything above high school math. I've used linear algebra once. I've never used calculus. I use algebra every day.

The best way to do it is:

return this.StatusCode(StatusCodes.Status418ImATeapot, "Error message");

'StatusCodes' has every kind of return status and you can see all of them in this link https://httpstatuses.com/

Once you choose your StatusCode, return it with a message.

I know this is and old question, but i was faced with the same problem recently and none of the answers worked for me:

• Couldn't find an old Foxit Reader version
• As @pilkch said 2Printer adds a report page
• Adobe Reader opens a gui

After searching a little more i found this: http://www.columbia.edu/~em36/pdftoprinter.html.

It's a simple exe that you call with the filename and it prints to the default printer (or one that you specify). From the site:

PDFtoPrinter is a program for printing PDF files from the Windows command line. The program is designed generally for the Windows command line and also for use with the vDos DOS emulator.

To print a PDF file to the default Windows printer, use this command:

PDFtoPrinter.exe filename.pdf

To print to a specific printer, add the name of the printer in quotation marks:

PDFtoPrinter.exe filename.pdf "Name of Printer"

If you want to print to a network printer, use the name that appears in Windows print dialogs, like this (and be careful to note the two backslashes at the start of the name and the single backslash after the servername):

PDFtoPrinter.exe filename.pdf "\\SERVER\PrinterName"

Assuming the field in timestamp firestore is called timestamp, in dart you could call the toDate() method on the returned map.

// Map from firestore
// Using flutterfire package hence the returned data()
Map<String, dynamic> data = documentSnapshot.data();
DateTime _timestamp = data['timestamp'].toDate();

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

If you are a Windows user, you may either remove or update your credentials in Credential Manager.

In Windows 10, go to the below path:

Control Panel → All Control Panel Items → Credential Manager

Or search for "credential manager" in your "Search Windows" section in the Start menu.

Then from the Credential Manager, select "Windows Credentials".

Credential Manager will show many items including your outlook and GitHub repository under "Generic credentials"

You click on the drop down arrow on the right side of your Git: and it will show options to edit and remove. If you remove, the credential popup will come next time when you fetch or pull. Or you can directly edit the credentials there.

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

The JOIN syntax keeps conditions near the table they apply to. This is especially useful when you join a large amount of tables.

By the way, you can do an outer join with the first syntax too:

WHERE a.x = b.x(+)

Or

WHERE a.x *= b.x

Or

WHERE a.x = b.x or a.x not in (select x from b)

dict.iteritems is gone in Python3.x So use iter(dict.items()) to get the same output and memory alocation

this.$http.get('https://pokeapi.co/api/v2/pokemon')
.then(response => {
   if(response.status === 200)
   {
      this.usuarios = response.data.results.map(usuario => {
      return { name: usuario.name, url: usuario.url, captched: false } })
          }
    })
.catch( error => { console.log("Error al Cargar los Datos: " + error ) } )

I had the same problem with bootstrap datetimepicker extension. Including moment.js before datetimepicker.js was the solution.

a:link -> It defines the style for unvisited links.

a:hover -> It defines the style for hovered links.

A link is hovered when the mouse moves over it.

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

To programmatically load a view from a nib/xib in Swift 4:

// Load a view from a Nib given a placeholder view subclass
//      Placeholder is an instance of the view to load.  Placeholder is discarded.
//      If no name is provided, the Nib name is the same as the subclass type name
//
public func loadViewFromNib<T>(placeholder placeholderView: T, name givenNibName: String? = nil) -> T {

    let nib = loadNib(givenNibName, placeholder: placeholderView)
    return instantiateView(fromNib: nib, placeholder: placeholderView)
}

// Step 1: Returns a Nib
//
public func loadNib<T>(_ givenNibName: String? = nil, placeholder placeholderView: T) -> UINib {
    //1. Load and unarchive nib file
    let nibName = givenNibName ?? String(describing: type(of: placeholderView))

    let nib = UINib(nibName: nibName, bundle: Bundle.main)
    return nib
}

// Step 2: Instantiate a view given a nib
//
public func instantiateView<T>(fromNib nib: UINib, placeholder placeholderView: T) -> T {
    //1. Get top level objects
    let topLevelObjects = nib.instantiate(withOwner: placeholderView, options: nil)

    //2. Have at least one top level object
    guard let firstObject = topLevelObjects.first else {
        fatalError("\(#function): no top level objects in nib")
    }

    //3. Return instantiated view, placeholderView is not used
    let instantiatedView = firstObject as! T
    return instantiatedView
}

If You want to compile a Delphi project, look at "ERROR MSB4040 There is no target in the project" when using msbuild+Delphi2009

Correct answer there are said: "There is a batch file called rsvars.bat (search for it in the RAD Studio folder). Call that before calling MSBuild, and it will setup the necessary environment variables. Make sure the folders are correct in rsvars.bat if you have the compiler in a different location to the default."

This bat will not only update the PATH environment variable to proper .NET folder with proper MSBuild.exe version, but also registers other necessary variables.

function millisToMinutesAndSeconds(millis) {
  var minutes = Math.floor(millis / 60000);
  var seconds = ((millis % 60000) / 1000).toFixed(0);
  return minutes + ":" + (seconds < 10 ? '0' : '') + seconds;
}

millisToMinutesAndSeconds(298999); // "4:59"
millisToMinutesAndSeconds(60999);  // "1:01"

As User HelpingHand pointed in the comments the return statement should be

return (seconds == 60 ? (minutes+1) + ":00" : minutes + ":" + (seconds < 10 ? "0" : "") + seconds);

An answer above got me 99% of the way there (thanks Denis Ivin!). For my PHP / MySQL implementation, I needed to change the syntax a little:

SELECT *
FROM UserProfile
WHERE PropertydefinitionID in (40, 53)
AND (LENGTH(IFNULL(PropertyValue,'')) = 0)

LEN becomes LENGTH and ISNULL becomes IFNULL.

I have the same issue when processing a file generated from Linux. It turns out it was related with files containing question marks..

We can define the so-called foreign key in MongoDB. However, we need to maintain the data integrity BY OURSELVES. For example,

student
{ 
  _id: ObjectId(...),
  name: 'Jane',
  courses: ['bio101', 'bio102']   // <= ids of the courses
}

course
{
  _id: 'bio101',
  name: 'Biology 101',
  description: 'Introduction to biology'
}

The courses field contains _ids of courses. It is easy to define a one-to-many relationship. However, if we want to retrieve the course names of student Jane, we need to perform another operation to retrieve the course document via _id.

If the course bio101 is removed, we need to perform another operation to update the courses field in the student document.

More: MongoDB Schema Design

The document-typed nature of MongoDB supports flexible ways to define relationships. To define a one-to-many relationship:

Embedded document

1. Suitable for one-to-few.
2. Advantage: no need to perform additional queries to another document.
3. Disadvantage: cannot manage the entity of embedded documents individually.

Example:

student
{
  name: 'Kate Monster',
  addresses : [
     { street: '123 Sesame St', city: 'Anytown', cc: 'USA' },
     { street: '123 Avenue Q', city: 'New York', cc: 'USA' }
  ]
}

Child referencing

Like the student/course example above.

Parent referencing

Suitable for one-to-squillions, such as log messages.

host
{
    _id : ObjectID('AAAB'),
    name : 'goofy.example.com',
    ipaddr : '127.66.66.66'
}

logmsg
{
    time : ISODate("2014-03-28T09:42:41.382Z"),
    message : 'cpu is on fire!',
    host: ObjectID('AAAB')       // Reference to the Host document
}

Virtually, a host is the parent of a logmsg. Referencing to the host id saves much space given that the log messages are squillions.

I tried MikeTeeVee's solution, still not work, I mean the selected tab still not change and keep different color. This post solved my problem: Set CSS class 'selected' in ASP.NET menu parents and their children? Need put code in code behind.

I had same problem (I'm from the Czech Republic). I have an English installation of Windows, and I have to work with files on a shared drive. Paths to the files include Czech-specific characters.

The solution that works for me is:

In the batch file, change the charset page

My batch file:

chcp 1250
copy "O:\VEREJNÉ\ŽŽŽŽŽŽ\Ž.xls" c:\temp

The batch file has to be saved in CP 1250.

Note that the console will not show characters correctly, but it will understand them...

This is how you call an instance method on the Controller:

@{
  ((HomeController)this.ViewContext.Controller).Method1();
}

This is how you call a static method in any class

@{
    SomeClass.Method();
}

This will work assuming the method is public and visible to the view.

The error message you are receiving is telling you that the application failed to connect to the sqlexpress db, and not sql server. I will just change the name of the db in sql server and then update the connectionstring accordingly and try it again.

Your error message states the following:

Cannot open database "Phaeton.mdf" requested by the login. The login failed.

It looks to me you are still trying to connect to the file based database, the name "Phaeton.mdf" does not match with your new sql database name "Phaeton".

Hope this helps.

java.time

With the Java 8 Date and Time API you can use the LocalDate class.

LocalDate.now().plusDays(nrOfDays)

See the Oracle Tutorial.

Look at snprintf or, if GNU extensions are OK, asprintf (which will allocate memory for you).

Simply getting navigation bar height may not be enough. We need to consider whether 1. navigation bar exists, 2. is it on the bottom, or right or left, 3. is app open in multi-window mode.

Fortunately you can easily bypass all the long coding by simply setting android:fitsSystemWindows="true" in your root layout. Android system will automatically take care of adding necessary padding to the root layout to make sure that the child views don't get into the navigation bar or statusbar regions.

There is a simple one line solution

android:fitsSystemWindows="true"

or programatically

findViewById(R.id.your_root_view).setFitsSystemWindows(true);

you may also get root view by

findViewById(android.R.id.content).getRootView();
or
getWindow().getDecorView().findViewById(android.R.id.content)

For more details on getting root-view refer - https://stackoverflow.com/a/4488149/9640177

You can not "attach" a SASS/SCSS file to an HTML document.

SASS/SCSS is a CSS preprocessor that runs on the server and compiles to CSS code that your browser understands.

There are client-side alternatives to SASS that can be compiled in the browser using javascript such as LESS CSS, though I advise you compile to CSS for production use.

It's as simple as adding 2 lines of code to your HTML file.

<link rel="stylesheet/less" type="text/css" href="styles.less" />
<script src="less.js" type="text/javascript"></script>

If you are working in node.js with lusca try also this:

$.ajax({
url: "http://test.com",
type:"post"
headers: {'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')}
})

I figured it out from the PostgreSQL docs, the exact syntax is:

ALTER TABLE the_table ADD CONSTRAINT constraint_name UNIQUE (thecolumn);

Thanks Fred.

Requires PHP 5.3 to work ("first day of" is introduced in PHP 5.3). Otherwise the example above is the only way to do it:

<?php
    // First day of this month
    $d = new DateTime('first day of this month');
    echo $d->format('jS, F Y');

    // First day of a specific month
    $d = new DateTime('2010-01-19');
    $d->modify('first day of this month');
    echo $d->format('jS, F Y');

    // alternatively...
    echo date_create('2010-01-19')
      ->modify('first day of this month')
      ->format('jS, F Y');

In PHP 5.4+ you can do this:

<?php
    // First day of this month
    echo (new DateTime('first day of this month'))->format('jS, F Y');

    echo (new DateTime('2010-01-19'))
      ->modify('first day of this month')
      ->format('jS, F Y');

If you prefer a concise way to do this, and already have the year and month in numerical values, you can use date():

<?php
    echo date('Y-m-01'); // first day of this month
    echo date("$year-$month-01"); // first day of a month chosen by you

The $ symbol simply invokes the jQuery library's selector functionality. So $("#Text") returns the jQuery object for the Text div which can then be modified.

char * msg = new char[65546]();

It's known as value-initialisation, and was introduced in C++03. If you happen to find yourself trapped in a previous decade, then you'll need to use std::fill() (or memset() if you want to pretend it's C).

Note that this won't work for any value other than zero. I think C++0x will offer a way to do that, but I'm a bit behind the times so I can't comment on that.

UPDATE: it seems my ruminations on the past and future of the language aren't entirely accurate; see the comments for corrections.

Templates must be used in headers because the compiler needs to instantiate different versions of the code, depending on the parameters given/deduced for template parameters. Remember that a template doesn't represent code directly, but a template for several versions of that code. When you compile a non-template function in a .cpp file, you are compiling a concrete function/class. This is not the case for templates, which can be instantiated with different types, namely, concrete code must be emitted when replacing template parameters with concrete types.

There was a feature with the export keyword that was meant to be used for separate compilation. The export feature is deprecated in C++11 and, AFAIK, only one compiler implemented it. You shouldn't make use of export. Separate compilation is not possible in C++ or C++11 but maybe in C++17, if concepts make it in, we could have some way of separate compilation.

For separate compilation to be achieved, separate template body checking must be possible. It seems that a solution is possible with concepts. Take a look at this paper recently presented at the standards commitee meeting. I think this is not the only requirement, since you still need to instantiate code for the template code in user code.

The separate compilation problem for templates I guess it's also a problem that is arising with the migration to modules, which is currently being worked.

EDIT: As of August 2020 Modules are already a reality for C++: https://en.cppreference.com/w/cpp/language/modules

I would suppose that you can use a variable in the result, but aside from getting the ORDER BY piece in a view, you will not see a benefit by implicitly stating "TOP 100 PERCENT":

declare @t int
set @t=100
select top (@t) percent * from tableOf

For the UPDATE

Use:

UPDATE table1 
   SET col1 = othertable.col2,
       col2 = othertable.col3 
  FROM othertable 
 WHERE othertable.col1 = 123;

For the INSERT

Use:

INSERT INTO table1 (col1, col2) 
SELECT col1, col2 
  FROM othertable

You don't need the VALUES syntax if you are using a SELECT to populate the INSERT values.

Simply do the following:

1. Open your .sql file with Notepad or Notepad ++

2. Find InnoDB and Replace all (around 87) with MyISAM

3. Save and now you can import your database with out error.

I want to supplement a way to copy the line to the clipboard and use it on the function.

here is an example that you open the URL in the browser

let g:chrome_exe = 'C:/.../Google/Chrome/Application/chrome.exe'
function OpenURL()
    " copy the line and put it in the register *
    normal "*yy
    :execute "silent !start ".g:chrome_exe." ".getreg("*")
endfunction

map ,url :call OpenURL()<CR>

Created the Data frame:

import pandas as pd
dk=pd.DataFrame({"BrandName":['A','B','ABC','D','AB'],"Specialty":['H','I','J','K','L']})

Now use DataFrame.replace() function:

dk.BrandName.replace(to_replace=['ABC','AB'],value='A')

it depends if your div is in position: absolute / fixed or relative / static

for position: absolute & fixed

<div style="position: absolute; /*or fixed*/;
width: 50%;
height: 300px;
left: 50%;
top:100px;
margin: 0 0 0 -25%">blblablbalba</div>

The trick here is to have a negative margin half the width of the object

for position: relative & static

<div style="position: relative; /*or static*/;
width: 50%;
height: 300px;
margin: 0 auto">blblablbalba</div>

for both techniques, it is imperative to set the width.

From the Finder, I went in Application/MAMP, showed files info (cmd + i) and in permissions section added myself with read & write perms, then from the little gear applied to all the children.

I had the same issue that automatically resolve after last Microsoft windows update, does anyone experience the same?

I think that what you want to do is turn the JSON string back into an object when it arrives back in your XMLHttpRequest - correct?

If so, you need to eval the string to turn it into a JavaScript object - note that this can be unsafe as you're trusting that the JSON string isn't malicious and therefore executing it. Preferably you could use jQuery's parseJSON

I've solved my problem by this way: Edit the php.ini file:

1. change extension_dir = "ext" into extension_dir = "D:\php\ext" (please write ur own path)
2. change ;extension=php_mbstring.dll into extension=php_mbstring.dll (delete the ";")
3. Then just save your php.ini file and copy it to ur Windows directory?(“C:\Windows“)
4. restart the apache server?

The above is my solution,Hope it will work for u.

It's ridiculous that java doesn't have this yet. Scala has it

import com.text.Formatter
import com.json.{Formatter => JsonFormatter}

val Formatter textFormatter;
val JsonFormatter jsonFormatter;

$('#div_id').css({marginTop: '-=15px'});

This will alter the css for the element with the id "div_id"

To get the effect you want I recommend adding the code above to a callback function in your animation (that way the div will be moved up after the animation is complete):

$('#div_id').animate({...}, function () {
    $('#div_id').css({marginTop: '-=15px'});
});

And of course you could animate the change in margin like so:

$('#div_id').animate({marginTop: '-=15px'});

Here are the docs for .css() in jQuery: http://api.jquery.com/css/

And here are the docs for .animate() in jQuery: http://api.jquery.com/animate/

In my case the path is not set in VPATH, after added the error gone.

The ONLY thing that worked for me was html.

And I found it to be the far easier to do than any of the programmatic approaches.

The following code changes the text color based on a parameter passed by a caller.

enum {msg_info, msg_notify, msg_alert};
:
:
void bits::sendMessage(QString& line, int level)
{
    QTextCursor cursor = ui->messages->textCursor();
    QString alertHtml  = "<font color=\"DeepPink\">";
    QString notifyHtml = "<font color=\"Lime\">";
    QString infoHtml   = "<font color=\"Aqua\">";
    QString endHtml    = "</font><br>";

    switch(level)
    {
        case msg_alert:  line = alertHtml % line; break;
        case msg_notify: line = notifyHtml % line; break;
        case msg_info:   line = infoHtml % line; break;
        default:         line = infoHtml % line; break;
    }

    line = line % endHtml;
    ui->messages->insertHtml(line);
    cursor.movePosition(QTextCursor::End);
    ui->messages->setTextCursor(cursor);
}

The map function can be very useful here. Using map we can apply any function to each element of an iterable.

Python 3.x

>>> def my_mul(x,y):
...     return x*y
...
>>> a = [1,2,3,4]
>>> b = [2,3,4,5]
>>>
>>> list(map(my_mul,a,b))
[2, 6, 12, 20]
>>>

Of course:

map(f, iterable)

is equivalent to

[f(x) for x in iterable]

So we can get our solution via:

>>> [my_mul(x,y) for x, y in zip(a,b)]
[2, 6, 12, 20]
>>>

In Python 2.x map() means: apply a function to each element of an iterable and construct a new list. In Python 3.x, map construct iterators instead of lists.

Instead of my_mul we could use mul operator

Python 2.7

>>>from operator import mul # import mul operator
>>>a = [1,2,3,4]
>>>b = [2,3,4,5]
>>>map(mul,a,b)
[2, 6, 12, 20]
>>>

Python 3.5+

>>> from operator import mul
>>> a = [1,2,3,4]
>>> b = [2,3,4,5]
>>> [*map(mul,a,b)]
[2, 6, 12, 20]
>>>

Please note that since map() constructs an iterator we use * iterable unpacking operator to get a list. The unpacking approach is a bit faster then the list constructor:

>>> list(map(mul,a,b))
[2, 6, 12, 20]
>>>

Another mysteriously unknown RDBMS. Your Syntax is perfectly fine in PostgreSQL. Other query styles may perform faster (especially the NOT EXISTS variant or a LEFT JOIN), but your query is perfectly legit.

Be aware of pitfalls with NOT IN, though, when involving any NULL values:

• Find records where join doesn't exist

Variant with LEFT JOIN:

SELECT *
FROM   friend f
LEFT   JOIN likes l USING (id1, id2)
WHERE  l.id1 IS NULL;

See @Michal's answer for the NOT EXISTS variant.
A more detailed assessment of four basic variants:

• Select rows which are not present in other table

This is array initializer syntax, and it can only be used on the right-hand-side when declaring a variable of array type. Example:

int[] x = {1,2,3,4};
String y = {"a","b","c"};

If you're not on the RHS of a variable declaration, use an array constructor instead:

int[] x;
x = new int[]{1,2,3,4};
String y;
y = new String[]{"a","b","c"};

These declarations have the exact same effect: a new array is allocated and constructed with the specified contents.

In your case, it might actually be clearer (less repetitive, but a bit less concise) to specify the table programmatically:

double[][] m = new double[4][4];

for(int i=0; i<4; i++) {
    for(int j=0; j<4; j++) {
        m[i][j] = i*j;
    }
}

43 is the dec ascii number for the "+" symbol. That explains why you get a 43 back. http://en.wikipedia.org/wiki/ASCII

Several GUI tools like Squirrel, SQL Workbench/J, AnySQL, ExecuteQuery can export to Excel files.

Most of those tools are listed in the PostgreSQL wiki:

In Python 3.3+:

from datetime import datetime, timezone

def utc_to_local(utc_dt):
    return utc_dt.replace(tzinfo=timezone.utc).astimezone(tz=None)

In Python 2/3:

import calendar
from datetime import datetime, timedelta

def utc_to_local(utc_dt):
    # get integer timestamp to avoid precision lost
    timestamp = calendar.timegm(utc_dt.timetuple())
    local_dt = datetime.fromtimestamp(timestamp)
    assert utc_dt.resolution >= timedelta(microseconds=1)
    return local_dt.replace(microsecond=utc_dt.microsecond)

Using pytz (both Python 2/3):

import pytz

local_tz = pytz.timezone('Europe/Moscow') # use your local timezone name here
# NOTE: pytz.reference.LocalTimezone() would produce wrong result here

## You could use `tzlocal` module to get local timezone on Unix and Win32
# from tzlocal import get_localzone # $ pip install tzlocal

# # get local timezone    
# local_tz = get_localzone()

def utc_to_local(utc_dt):
    local_dt = utc_dt.replace(tzinfo=pytz.utc).astimezone(local_tz)
    return local_tz.normalize(local_dt) # .normalize might be unnecessary

Example

def aslocaltimestr(utc_dt):
    return utc_to_local(utc_dt).strftime('%Y-%m-%d %H:%M:%S.%f %Z%z')

print(aslocaltimestr(datetime(2010,  6, 6, 17, 29, 7, 730000)))
print(aslocaltimestr(datetime(2010, 12, 6, 17, 29, 7, 730000)))
print(aslocaltimestr(datetime.utcnow()))

Output

2010-06-06 21:29:07.730000 MSD+0400

2012-11-08 14:19:50.146917 MSK+0400

Note: it takes into account DST and the recent change of utc offset for MSK timezone.

I don't know whether non-pytz solutions work on Windows.

You need to dynamically allocate your matrix. For instance:

int* mat;
int dimx,dimy;
scanf("%d", &dimx);
scanf("%d", &dimy);
mat = malloc(dimx * dimy * sizeof(int));

This creates a linear array which can hold the matrix. At this point you can decide whether you want to access it column or row first. I would suggest making a quick macro which calculates the correct offset in the matrix.

1. Create your shell script as login.sh in your $HOME folder.

2. Paste the following one-line script into Script Editor:

   do shell script "$HOME/login.sh"

3. Then save it as an application.

4. Finally add the application to your login items.

If you want to make the script output visual, you can swap step 2 for this:

tell application "Terminal"
  activate
  do script "$HOME/login.sh"
end tell

If multiple commands are needed something like this can be used:

tell application "Terminal"
  activate
  do script "cd $HOME"
  do script "./login.sh" in window 1
end tell

I use this:

var strDate = $("#dateTo").datepicker('getDate').format('yyyyMMdd');

Which returns a date of format like "20120118" for Jan 18, 2012.

its work short code

$('.SeeMore2').click(function(){ var $this = $(this).toggleClass('SeeMore2'); if($(this).hasClass('SeeMore2')) { $(this).text('See More');
} else { $(this).text('See Less'); } });

Also in the many IDEs now, ex: VSC, you can install an extension for AWS and simply click upload from there, no effort of typing all those commands + region.

Here's an example:

If the image size is variable or the design is responsive, in addition to wrapping the text, you can set a min width for the paragraph to avoid it to become too narrow.
Give an invisible CSS pseudo-element with the desired minimum paragraph width. If there isn't enough space to fit this pseudo-element, then it will be pushed down underneath the image, taking the paragraph with it.

#container:before {
  content: ' ';
  display: table;
  width: 10em;    /* Min width required */
}
#floated{
    float: left;
    width: 150px;
    background: red;
}

I am using :: Spring Boot :: (v2.0.4.RELEASE) with Spring Framework 5

Spring Boot 2.0 requires Java 8 as a minimum version. Many existing APIs have been updated to take advantage of Java 8 features such as: default methods on interfaces, functional callbacks, and new APIs such as javax.time.

By default, Spring Boot serves static content from a directory called /static (or /public or /resources or /META-INF/resources) in the classpath or from the root of the ServletContext. It uses the ResourceHttpRequestHandler from Spring MVC so that you can modify that behavior by adding your own WebMvcConfigurer and overriding the addResourceHandlers method.

By default, resources are mapped on /** and located on /static directory. But you can customize the static loactions programmatically inside our web context configuration class.

@Configuration @EnableWebMvc
public class Static_ResourceHandler implements WebMvcConfigurer {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        // When overriding default behavior, you need to add default(/) as well as added static paths(/webapp).

        // src/main/resources/static/...
        registry
            //.addResourceHandler("/**") // « /css/myStatic.css
            .addResourceHandler("/static/**") // « /static/css/myStatic.css
            .addResourceLocations("classpath:/static/") // Default Static Loaction
            .setCachePeriod( 3600 )
            .resourceChain(true) // 4.1
            .addResolver(new GzipResourceResolver()) // 4.1
            .addResolver(new PathResourceResolver()); //4.1

        // src/main/resources/templates/static/...
        registry
            .addResourceHandler("/templates/**") // « /templates/style.css
            .addResourceLocations("classpath:/templates/static/");

        // Do not use the src/main/webapp/... directory if your application is packaged as a jar.
        registry
            .addResourceHandler("/webapp/**") // « /webapp/css/style.css
            .addResourceLocations("/");

        // File located on disk
        registry
            .addResourceHandler("/system/files/**")
            .addResourceLocations("file:///D:/");
    }
}

http://localhost:8080/handlerPath/resource-path+name
                    /static         /css/myStatic.css
                    /webapp         /css/style.css
                    /templates      /style.css

In Spring every request will go through the DispatcherServlet. To avoid Static file request through DispatcherServlet(Front contoller) we configure MVC Static content.

As @STEEL said static resources should not go through Controller. Thymleaf is a ViewResolver which takes the view name form controller and adds prefix and suffix to View Layer.

public void expand(final View v) {
        ScaleAnimation scaleAnimation = new ScaleAnimation(1, 1, 1, 0, 0, 0);

If you want case-insensitive comparison, use lower or upper:

if name.lower() == "jesse":

In python re, you can span from numberic to upper case alpha. So..

import re
test = "01234ABCDEFGHIJKabcdefghijk01234abcdefghijkABCDEFGHIJK"
re.compile(r'[0-f]+').findall(test) # Bad: matches all uppercase alpha chars
## ['01234ABCDEFGHIJKabcdef', '01234abcdef', 'ABCDEFGHIJK']
re.compile(r'[0-F]+').findall(test) # Partial: does not match lowercase hex chars
## ['01234ABCDEF', '01234', 'ABCDEF']
re.compile(r'[0-F]+', re.I).findall(test) # Good
## ['01234ABCDEF', 'abcdef', '01234abcdef', 'ABCDEF']
re.compile(r'[0-f]+', re.I).findall(test) # Good
## ['01234ABCDEF', 'abcdef', '01234abcdef', 'ABCDEF']
re.compile(r'[0-Fa-f]+').findall(test) # Good (with uppercase-only magic)
## ['01234ABCDEF', 'abcdef', '01234abcdef', 'ABCDEF']
re.compile(r'[0-9a-fA-F]+').findall(test) # Good (with no magic)
## ['01234ABCDEF', 'abcdef', '01234abcdef', 'ABCDEF']

That makes the simplest Python UUID regex:

re_uuid = re.compile("[0-F]{8}-([0-F]{4}-){3}[0-F]{12}", re.I)

I'll leave it as an exercise to the reader to use timeit to compare the performance of these.

Enjoy. Keep it Pythonic™!

NOTE: Those spans will also match :;<=>?@' so, if you suspect that could give you false positives, don't take the shortcut. (Thank you Oliver Aubert for pointing that out in the comments.)

Please check that your form tag have this attribute:

enctype="multipart/form-data"

A pandas MultiIndex consists of a list of tuples. So the most natural approach would be to reshape your input dict so that its keys are tuples corresponding to the multi-index values you require. Then you can just construct your dataframe using pd.DataFrame.from_dict, using the option orient='index':

user_dict = {12: {'Category 1': {'att_1': 1, 'att_2': 'whatever'},
                  'Category 2': {'att_1': 23, 'att_2': 'another'}},
             15: {'Category 1': {'att_1': 10, 'att_2': 'foo'},
                  'Category 2': {'att_1': 30, 'att_2': 'bar'}}}

pd.DataFrame.from_dict({(i,j): user_dict[i][j] 
                           for i in user_dict.keys() 
                           for j in user_dict[i].keys()},
                       orient='index')


               att_1     att_2
12 Category 1      1  whatever
   Category 2     23   another
15 Category 1     10       foo
   Category 2     30       bar

An alternative approach would be to build your dataframe up by concatenating the component dataframes:

user_ids = []
frames = []

for user_id, d in user_dict.iteritems():
    user_ids.append(user_id)
    frames.append(pd.DataFrame.from_dict(d, orient='index'))

pd.concat(frames, keys=user_ids)

               att_1     att_2
12 Category 1      1  whatever
   Category 2     23   another
15 Category 1     10       foo
   Category 2     30       bar

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

I use the following object:

function Padder(len, pad) {
  if (len === undefined) {
    len = 1;
  } else if (pad === undefined) {
    pad = '0';
  }

  var pads = '';
  while (pads.length < len) {
    pads += pad;
  }

  this.pad = function (what) {
    var s = what.toString();
    return pads.substring(0, pads.length - s.length) + s;
  };
}

With it you can easily define different "paddings":

var zero4 = new Padder(4);
zero4.pad(12); // "0012"
zero4.pad(12345); // "12345"
zero4.pad("xx"); // "00xx"
var x3 = new Padder(3, "x");
x3.pad(12); // "x12"

This is what I use:

stat -f %N $your_path

The NUMBER type can be specified in different styles:

                Resulting  Resulting  Precision
Specification   Precision  Scale      Check      Comment
-------------------------------------------------------------------------------
NUMBER          NULL       NULL       NO         'maximum range and precision',
                                                 values are stored 'as given'
NUMBER(P, S)    P          S          YES        Error code: ORA-01438
NUMBER(P)       P          0          YES        Error code: ORA-01438
NUMBER(*, S)    38         S          NO

Where the precision is the total number of digits and scale is the number of digits right or left (negative scale) of the decimal point.

Oracle specifies ORA-01438 as

value larger than specified precision allowed for this column

As noted in the table, this integrity check is only active if the precision is explicitly specified. Otherwise Oracle silently rounds the inserted or updated value using some unspecified method.

It worked for me, but the exe4j can leave a signature when you double click the .exe application

you should examine the specification before using 'remainder' operator % :

As other posters already indicated; your system clock is probably not synchronized up to microseconds to actual world time. Nonetheless are microsecond precision timestamps useful as a hybrid for both indicating current wall time, and measuring/profiling the duration of things.

I label all events/messages written to a log files using timestamps like "2012-10-21 19:13:45.267128". These convey both when it happened ("wall" time), and can also be used to measure the duration between this and the next event in the log file (relative difference in microseconds).

To achieve this, you need to link System.currentTimeMillis() with System.nanoTime() and work exclusively with System.nanoTime() from that moment forward. Example code:

/**
 * Class to generate timestamps with microsecond precision
 * For example: MicroTimestamp.INSTANCE.get() = "2012-10-21 19:13:45.267128"
 */ 
public enum MicroTimestamp 
{  INSTANCE ;

   private long              startDate ;
   private long              startNanoseconds ;
   private SimpleDateFormat  dateFormat ;

   private MicroTimestamp()
   {  this.startDate = System.currentTimeMillis() ;
      this.startNanoseconds = System.nanoTime() ;
      this.dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS") ;
   }

   public String get()
   {  long microSeconds = (System.nanoTime() - this.startNanoseconds) / 1000 ;
      long date = this.startDate + (microSeconds/1000) ;
      return this.dateFormat.format(date) + String.format("%03d", microSeconds % 1000) ;
   }
}

For those using Cobertura and only have the Coverage Session View like I do,just try closing Eclipse and starting it up again. This got rid of the highlighting for me.

Write yourself a Helper function:

public static bool IsBewteenTwoDates(this DateTime dt, DateTime start, DateTime end)
{
    return dt >= start && dt <= end;
}

Then call: .IsBewteenTwoDates(DateTime.Today ,new DateTime(,,));

I had this same problem installing my app to a server. It ended up being the installer project, it wasn't installing all the files needed to run the web app. I tried to figure out where it was broken but in the end I had to revert the project to the previous version to fix it. Hope this helps someone...

this condition chick all cases.

function del() {_x000D_
//chick if dom has this element _x000D_
//if not true condition means null or undifind or false ._x000D_
_x000D_
if (!document.querySelector("#ul_list ")===true){_x000D_
_x000D_
// msg to user_x000D_
    alert("click btn load ");_x000D_
_x000D_
// if console chick for you and show null clear console._x000D_
    console.clear();_x000D_
_x000D_
// the function will stop._x000D_
    return false;_x000D_
}_x000D_
_x000D_
// if its true function will log delet ._x000D_
console.log("delet");_x000D_
_x000D_
}

Pass it as an Object:

$(....).css({
    'property': 'value', 
    'property': 'value'

With HTML 5 we can use a new feature "required" the just add it to the tag which you want to be required like:

<input type='text' required>

My problem case was to run portecle.jnlp file locally using Java8.

What worked for me was

1. Start Programs --> Java --> Configure Java...
2. Go to Security --> Edit Site List...
3. Add http://portecle.sourceforce.net
4. Start javaws portecle.jnlp in CMD prompt

On step 3, you might try also to add file:///c:/path/portecle.jnlp, but this addition didn't help with my case.

System.String is a reference type and already "nullable".

Nullable<T> and the ? suffix are for value types such as Int32, Double, DateTime, etc.

I'd say it depends on what you need it for:

1. If you need it just to get 3 columns layout, I'd suggest to do it with float.

2. If you need it for menu, you can use inline-block. For the whitespace problem, you can use few tricks as described by Chris Coyier here http://css-tricks.com/fighting-the-space-between-inline-block-elements/.

3. If you need to make a multiple choice option, which the width needs to spread evenly inside a specified box, then I'd prefer display: table. This will not work correctly in some browsers, so it depends on your browser support.

Lastly, what might be the best method is using flexbox. The spec for this has changed few times, so it's not stable just yet. But once it has been finalized, this will be the best method I reckon.

SELECT * INTO table2 FROM table1;

There is now a way to easily do this in most modern browsers using

document.execCommand('copy');

This will copy currently selected text. You can select a textArea or input field using

document.getElementById('myText').select();

To invisibly copy text you can quickly generate a textArea, modify the text in the box, select it, copy it, and then delete the textArea. In most cases this textArea wont even flash onto the screen.

For security reasons, browsers will only allow you copy if a user takes some kind of action (ie. clicking a button). One way to do this would be to add an onClick event to a html button that calls a method which copies the text.

A full example:

function copier(){_x000D_
  document.getElementById('myText').select();_x000D_
  document.execCommand('copy');_x000D_
}

<button onclick="copier()">Copy</button>_x000D_
<textarea id="myText">Copy me PLEASE!!!</textarea>
