KOUT[i] is a single element of a list. But you are assigning a list to this element. your func is generating a list.

I think you can use onAttachFragment event may be useful to catch which fragment is active.

@Override
public void onAttachFragment(Fragment fragment) {
    // TODO Auto-generated method stub
    super.onAttachFragment(fragment);

    Toast.makeText(getApplicationContext(), String.valueOf(fragment.getId()), Toast.LENGTH_SHORT).show();

}

@nick-keets's solution is most elegant, but it did break down for me in test target with the following compile time error:

Redundant conformance of 'String' to protocol 'Error'

Here's another approach:

struct RuntimeError: Error {
    let message: String

    init(_ message: String) {
        self.message = message
    }

    public var localizedDescription: String {
        return message
    }
}

And to use:

throw RuntimeError("Error message.")

Count and show keys in a dictionary (run in console):

o=[];count=0; for (i in topicNames) { ++count; o.push(count+": "+ i) } o.join("\n")

Sample output:

"1: Phase-out Left-hand
2: Define All Top Level Taxonomies But Processes
3: 987
4: 16:00
5: Identify suppliers"

Simple count function:

function size_dict(d){c=0; for (i in d) ++c; return c}

int i;
string whatever;

//Best since no exception raised
int.TryParse(whatever, out i);

//Better use try catch on this one
i = Convert.ToInt32(whatever);

Try this It may be more appropriate for you

#container { display:block; }_x000D_
@media only screen and (orientation:portrait){_x000D_
  #container {  _x000D_
    height: 100vw;_x000D_

     -moz-transform: rotate(0deg);_x000D_
     -o-transform: rotate(0deg);_x000D_
     -ms-transform: rotate(0deg);_x000D_
     transform: rotate(0deg);_x000D_
  }_x000D_
}

<div id="container">_x000D_
    <!-- your html for your website -->_x000D_
    <H1>This text is always in Landscape Mode</H1>_x000D_
</div>

This will automatically manage even rotation.

I just can't believe that there are people still using ViewData/ViewBag in ASP.NET MVC 3 instead of having strongly typed views and view models:

public class MyViewModel
{
    [Required]
    public string CategoryId { get; set; }

    public IEnumerable<Category> Categories { get; set; }
}

and in your controller:

public class HomeController: Controller
{
    public ActionResult Index()
    {
        var model = new MyViewModel
        {
            Categories = Repository.GetCategories()
        }
        return View(model);
    }

    [HttpPost]
    public ActionResult Index(MyViewModel model)
    {
        if (!ModelState.IsValid)
        {
            // there was a validation error =>
            // rebind categories and redisplay view
            model.Categories = Repository.GetCategories();
            return View(model);
        }
        // At this stage the model is OK => do something with the selected category
        return RedirectToAction("Success");
    }
}

and then in your strongly typed view:

@Html.DropDownListFor(
    x => x.CategoryId, 
    new SelectList(Model.Categories, "ID", "CategoryName"), 
    "-- Please select a category --"
)
@Html.ValidationMessageFor(x => x.CategoryId)

Also if you want client side validation don't forget to reference the necessary scripts:

<script src="@Url.Content("~/Scripts/jquery.validate.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.js")" type="text/javascript"></script>

I made the following code so that even beginners can understand. Just copy the code and read comments. Note that message to be send is declared as a global variable which you can change just before sending the message. General changes can be done in Handler function.

add margin:-1px; which reduces 1px to each side. or if you need only for side you can do margin-left:-1px etc.

New Way

Starting with Go 1.16, use os.ReadFile to load the file to memory, use os.WriteFile to write to a file from memory.

Be careful with the os.ReadFile because it reads the whole file into memory.

package main

import "os"

func main() {
    b, err := os.ReadFile("input.txt")
    if err != nil {
        log.Fatal(err)
    }

    // `data` contains everything your file does
    // This writes it to the Standard Out
    os.Stdout.Write(data)

    // You can also write it to a file as a whole
    err = os.WriteFile("destination.txt", b, 0644)
    if err != nil {
        log.Fatal(err)
    }
}

If you don't mind using an external library, Lodash has lots of wonderful utilities

var people = [
  {
     "f_name":"john",
     "l_name":"doe",
     "sequence":"0",
     "title":"president",
     "url":"google.com",
     "color":"333333"
  },
  {
     "f_name":"michael",
     "l_name":"goodyear",
     "sequence":"0",
     "title":"general manager",
     "url":"google.com",
     "color":"333333"
  }
];


var sorted = _.sortBy(people, "l_name")

You can also sort by multiple properties. Here's a plunk showing it in action

Here is my own version, using regular expressions. This code assumes that each section name is unique - if however this is not true - it makes sense to replace Dictionary with List. This function supports .ini file commenting, starting from ';' character. Section starts normally [section], and key value pairs also comes normally "key = value". Same assumption as for sections - key name is unique.

/// <summary>
/// Loads .ini file into dictionary.
/// </summary>
public static Dictionary<String, Dictionary<String, String>> loadIni(String file)
{
    Dictionary<String, Dictionary<String, String>> d = new Dictionary<string, Dictionary<string, string>>();

    String ini = File.ReadAllText(file);

    // Remove comments, preserve linefeeds, if end-user needs to count line number.
    ini = Regex.Replace(ini, @"^\s*;.*$", "", RegexOptions.Multiline);

    // Pick up all lines from first section to another section
    foreach (Match m in Regex.Matches(ini, "(^|[\r\n])\\[([^\r\n]*)\\][\r\n]+(.*?)(\\[([^\r\n]*)\\][\r\n]+|$)", RegexOptions.Singleline))
    {
        String sectionName = m.Groups[2].Value;
        Dictionary<String, String> lines = new Dictionary<String, String>();

        // Pick up "key = value" kind of syntax.
        foreach (Match l in Regex.Matches(ini, @"^\s*(.*?)\s*=\s*(.*?)\s*$", RegexOptions.Multiline))
        {
            String key = l.Groups[1].Value;
            String value = l.Groups[2].Value;

            // Open up quotation if any.
            value = Regex.Replace(value, "^\"(.*)\"$", "$1");

            if (!lines.ContainsKey(key))
                lines[key] = value;
        }

        if (!d.ContainsKey(sectionName))
            d[sectionName] = lines;
    }

    return d;
}

Super Key: A superkey is any set of attributes for which the values are guaranteed to be unique for all possible set of tuples in a table at all time.

Candidate Key: A candidate key is a 'minimal' super key meaning the smallest subset of superkey attribute which is unique.

$st = $data->prepare("SELECT * FROM exampleWHERE example LIKE :search LIMIT 10"); 

How about a workaround? In my case I took the value of the textarea in a jQuery variable, and changed all "<p>&nbsp" to <p class="clear"> and clear class to have certain height and margin, as the following example:

jQuery

tinyMCE.triggerSave();
var val = $('textarea').val();
val = val.replace(/<p>&nbsp/g, '<p class="clear">');

the val is then saved to the database with the new val.

CSS

p.clear{height: 2px; margin-bottom: 3px;}

You can adjust the height & margin as you wish. And since 'p' is a display: block element. it should give you the expected output.

Hope that helps!

I recommend IdentityServer.This is a .NET Foundation project and covers many issues about authentication and authorization.

Overview

IdentityServer is a .NET/Katana-based framework and hostable component that allows implementing single sign-on and access control for modern web applications and APIs using protocols like OpenID Connect and OAuth2. It supports a wide range of clients like mobile, web, SPAs and desktop applications and is extensible to allow integration in new and existing architectures.

For more information, e.g.

• support for MembershipReboot and ASP.NET Identity based user stores
• support for additional Katana authentication middleware (e.g. Google, Twitter, Facebook etc)
• support for EntityFramework based persistence of configuration
• support for WS-Federation
• extensibility

check out the documentation and the demo.

There were just a couple of minor amendments required:

ans=True
while ans:
    print ("""
    1.Add a Student
    2.Delete a Student
    3.Look Up Student Record
    4.Exit/Quit
    """)
    ans=raw_input("What would you like to do? ") 
    if ans=="1": 
      print("\n Student Added") 
    elif ans=="2":
      print("\n Student Deleted") 
    elif ans=="3":
      print("\n Student Record Found") 
    elif ans=="4":
      print("\n Goodbye") 
    elif ans !="":
      print("\n Not Valid Choice Try again") 

I have changed the four quotes to three (this is the number required for multiline quotes), added a closing bracket after "What would you like to do? " and changed input to raw_input.

SQL Server and the .NET Framework are based on different type systems. For example, the .NET Framework Decimal structure has a maximum scale of 28, whereas the SQL Server decimal and numeric data types have a maximum scale of 38. Click Here's a link! for detail

1. Create the ArrayList like ArrayList action.

   In JDK 1.5 or higher use ArrayList <string[]> reference name.

   In JDK 1.4 or lower use ArrayList reference name.

2. Specify the access specifiers:

   • public, can be accessed anywhere
   • private, accessed within the class
   • protected, accessed within the class and different package subclasses

3. Then specify the reference it will be assigned in

   action = new ArrayList<String[]>();
   

4. In JVM new keyword will allocate memory in runtime for the object.

   You should not assigned the value where declared, because you are asking without fixed size.

5. Finally you can be use the add() method in ArrayList. Use like

   action.add(new string[how much you need])
   

   It will allocate the specific memory area in heap.

Facebook Developer Wiki (unofficial) contain not only list of FQL error codes but others too it's somehow updated but not contain full list of possible error codes.

There is no any official or updated (I mean really updated) list of error codes returned by Graph API. Every list that can be found online is outdated and not help that much...

There is official list describing some of API Errors and basic recovery tactics. Also there is couple of offcial lists for specific codes:

• Graph API › Errors
• OAuth Errors
• Credits Error codes - Facebook Credits is unsupported from Sep 2013
• Payments Error codes

" In computer networking, a network host, Internet host, host, or Internet node is a computer connected to the Internet - or more generically - to any type of data network. A network host can host information resources as well as application software for providing network services. "-Wikipedia

Local host is a special name given to the local machine or that you are working on, ussually its IP Address is 127.0.0.1. However you can define it to be anything.

There are multiple Network services running on each host for example Apache/IIS( Http Web Server),Mail Clients, FTP clients etc. Each service has a specific port associated with it. You can think of it as this.

In every home, there is one mailbox and multiple people. The mailbox is a host. Your own home mailbox is a localhost. Each person in a home has a room. All letters for that person are sent to his room, hence the room number is a port.

=> S, t, a, c, k, M, e, H, e, p, p, a, o, e, u

function doSomething(element) {
  var form = element.form;
}

and in the html, you need to find that element, and add the attribut "form" to connect to that form, please refer to http://www.w3schools.com/tags/att_input_form.asp but this form attr doesn't support IE, for ie, you need to pass form id directly.

function insertOrdered(array, elem) {
    let _array = array;
    let i = 0;
    while ( i < array.length && array[i] < elem ) {i ++};
    _array.splice(i, 0, elem);
    return _array;
}

What about just: :%s/\r//g That totally worked for me.

What this does is just to clean the end of line of all lines, it removes the ^M and that's it.

To this case, I have a hexadecimal data format into an int array and I want to convert them on String.

int[] encodeHex = new int[] { 0x48, 0x65, 0x6c, 0x6c, 0x6f }; // Hello encode
for (int i = 0; i < encodeHex.length; i++) {
   System.out.print((char) (encodeHex[i]));
}

Q:How to access name array text field

<input type="text" id="task" name="task[]" />

Answer - Using Input name array :

$('input[name="task\\[\\]"]').eq(0).val()
$('input[name="task\\[\\]"]').eq(index).val()

You need to add the command 'go' after you set the identity insert. Example:

SET IDENTITY_INSERT sometableWithIdentity ON
go

INSERT sometableWithIdentity (IdentityColumn, col2, col3, ...)
VALUES (AnIdentityValue, col2value, col3value, ...)

SET IDENTITY_INSERT sometableWithIdentity OFF
go

If you give each of these instances a class you can use

$('.yourClass').upload()

You can implement a filter method yourself that meets your needs, here is how:

function myfilter(array, test){
    var passedTest =[];
    for (var i = 0; i < array.length; i++) {
       if(test( array[i]))
          passedTest.push(array[i]);
    }

    return passedTest;
}

var passedHomes = myfilter(homes,function(currentHome){
     return ((currentHome.price <= 1000 )&& (currentHome.sqft >= 500 )&&(currentHome.num_of_beds >=2 )&&(currentHome.num_of_baths >= 2.5));
});

Hope, it helps!

Since this is homework:

Check out random.sample() which will select and return a random element from an list. You can get a list of dictionary keys with dict.keys() and a list of dictionary values with dict.values().

Summary of solution:

directory is neither an existing file nor directory. As it turns out, the real name is directory.1 as revealed by ls -la $HOME/Desktop/.

The complete working command is

cp -R $HOME/directory.1/file.bundle /library/application\ support/directory/

with the -R parameter for recursive copy (compulsory for copying directories).

I had the same problem and it was because there was a program using some file and git throws an error in this case Visual Studio had locked that file.

please try to make it as a character

string str = "Tigger";
//then str[0] will return 'T' not "T"

Yes, that is one way to get the first line of output from a command.

If the command outputs anything to standard error that you would like to capture in the same manner, you need to redirect the standard error of the command to the standard output stream:

utility 2>&1 | head -n 1

There are many other ways to capture the first line too, including sed 1q (quit after first line), sed -n 1p (only print first line, but read everything), awk 'FNR == 1' (only print first line, but again, read everything) etc.

A more modern solution that utilises the URL WebAPI:

(req, res) => {
  const { pathname } = new URL(req.url || '', `https://${req.headers.host}`)
}

select SUBSTRING_INDEX(supplier_reference,'=',-1) from ps_product;

Please use http://www.w3resource.com/mysql/string-functions/mysql-substring_index-function.php for further reference.

1) Use onbeforeunload, not onunload.

2) The important thing is to avoid executing a return statement. I don't mean, by this, to avoid returning from your handler. You return all right, but you do it by ensuring that you reach the end of the function and DO NOT execute a return statement. Under these conditions the built-in standard dialog does not occur.

3) You can, if you use onbeforeunload, run an ajax call in your unbeforeunload handler to tidy up on the server, but it must be a synchronous one, and you have to wait for and handle the reply in your onbeforeunload handler (still respecting condition (2) above). I do this and it works fine. If you do a synchronous ajax call, everything is held up until the response comes back. If you do an asynchronous one, thinking that you don't care about the reply from the server, the page unload continues and your ajax call is aborted by this process - including a remote script if it's running.

it's very simple we can use a parent element div to wrap all the element or we can use the Higher Order Component( HOC's ) concept i.e very useful for react js applications

render() {
  return (
    <div>
      <div>foo</div>
      <div>bar</div>
    </div>
  );
}

or another best way is HOC its very simple not very complicated just add a file hoc.js in your project and simply add these codes

const aux = (props) => props.children;
export default aux;

now import hoc.js file where you want to use, now instead of wrapping with div element we can wrap with hoc.

import React, { Component } from 'react';
import Hoc from '../../../hoc';

    render() {
      return (
    <Hoc>
        <div>foo</div>
        <div>bar</div>
    </Hoc>
      );
    }

I was also trying for transparency - maybe you could try leaving blank the value of background e.g. something like

bgcolor=" "

>>> 2 == 2.0
True
>>> 2 is 2.0
False

Use ==

Based on Crescent Fresh answer

if you want to detect links with http:// OR without http:// and by www. you can use the following

function urlify(text) {
    var urlRegex = /(((https?:\/\/)|(www\.))[^\s]+)/g;
    //var urlRegex = /(https?:\/\/[^\s]+)/g;
    return text.replace(urlRegex, function(url,b,c) {
        var url2 = (c == 'www.') ?  'http://' +url : url;
        return '<a href="' +url2+ '" target="_blank">' + url + '</a>';
    }) 
}

1. When async setting is set to false, a Synchronous call is made instead of an Asynchronous call.
2. When the async setting of the jQuery AJAX function is set to true then a jQuery Asynchronous call is made. AJAX itself means Asynchronous JavaScript and XML and hence if you make it Synchronous by setting async setting to false, it will no longer be an AJAX call.

I think the best option in Terms of performance (or in any terms) is to Distinct using the The IEqualityComparer interface.

Although implementing each time a new comparer for each class is cumbersome and produces boilerplate code.

So here is an extension method which produces a new IEqualityComparer on the fly for any class using reflection.

Usage:

var filtered = taskList.DistinctBy(t => t.TaskExternalId).ToArray();

Extension Method Code

public static class LinqExtensions
{
    public static IEnumerable<T> DistinctBy<T, TKey>(this IEnumerable<T> items, Func<T, TKey> property)
    {
        GeneralPropertyComparer<T, TKey> comparer = new GeneralPropertyComparer<T,TKey>(property);
        return items.Distinct(comparer);
    }   
}
public class GeneralPropertyComparer<T,TKey> : IEqualityComparer<T>
{
    private Func<T, TKey> expr { get; set; }
    public GeneralPropertyComparer (Func<T, TKey> expr)
    {
        this.expr = expr;
    }
    public bool Equals(T left, T right)
    {
        var leftProp = expr.Invoke(left);
        var rightProp = expr.Invoke(right);
        if (leftProp == null && rightProp == null)
            return true;
        else if (leftProp == null ^ rightProp == null)
            return false;
        else
            return leftProp.Equals(rightProp);
    }
    public int GetHashCode(T obj)
    {
        var prop = expr.Invoke(obj);
        return (prop==null)? 0:prop.GetHashCode();
    }
}

First, upvote (at the least) alsami's answer. That got me on the right path.

But for those of you doing IoC, here is a little bit of a deeper dive.

My error (same as others)

One or more errors occurred. (A second operation started on this context before a previous operation completed. This is usually caused by different threads using the same instance of DbContext. For more information on how to avoid threading issues with DbContext, see https://go.microsoft.com/fwlink/?linkid=2097913.)

My code setup. "Just the basics"...

public class MyCoolDbContext: DbContext{
    public DbSet <MySpecialObject> MySpecialObjects {        get;        set;    }
}

and

public interface IMySpecialObjectDomainData{}

and (note MyCoolDbContext is being injected)

public class MySpecialObjectEntityFrameworkDomainDataLayer: IMySpecialObjectDomainData{
    public MySpecialObjectEntityFrameworkDomainDataLayer(MyCoolDbContext context) {
        /* HERE IS WHERE TO SET THE BREAK POINT, HOW MANY TIMES IS THIS RUNNING??? */
        this.entityDbContext = context ?? throw new ArgumentNullException("MyCoolDbContext is null", (Exception)null);
    }
}

and

public interface IMySpecialObjectManager{}

and

public class MySpecialObjectManager: IMySpecialObjectManager
{
    public const string ErrorMessageIMySpecialObjectDomainDataIsNull = "IMySpecialObjectDomainData is null";
    private readonly IMySpecialObjectDomainData mySpecialObjectDomainData;

    public MySpecialObjectManager(IMySpecialObjectDomainData mySpecialObjectDomainData) {
        this.mySpecialObjectDomainData = mySpecialObjectDomainData ?? throw new ArgumentNullException(ErrorMessageIMySpecialObjectDomainDataIsNull, (Exception)null);
    }
}

And finally , my multi threaded class, being called from a Console App(Command Line Interface app)

    public interface IMySpecialObjectThatSpawnsThreads{}

and

public class MySpecialObjectThatSpawnsThreads: IMySpecialObjectThatSpawnsThreads
{
    public const string ErrorMessageIMySpecialObjectManagerIsNull = "IMySpecialObjectManager is null";

    private readonly IMySpecialObjectManager mySpecialObjectManager;

    public MySpecialObjectThatSpawnsThreads(IMySpecialObjectManager mySpecialObjectManager) {
        this.mySpecialObjectManager = mySpecialObjectManager ?? throw new ArgumentNullException(ErrorMessageIMySpecialObjectManagerIsNull, (Exception)null);
    }
}

and the DI buildup. (Again, this is for a console application (command line interface)...which exhibits slight different behavior than web-apps)

private static IServiceProvider BuildDi(IConfiguration configuration) {
    /* this is being called early inside my command line application ("console application") */

    string defaultConnectionStringValue = string.Empty; /* get this value from configuration */

    ////setup our DI
    IServiceCollection servColl = new ServiceCollection()
        ////.AddLogging(loggingBuilder => loggingBuilder.AddConsole())

        /* THE BELOW TWO ARE THE ONES THAT TRIPPED ME UP.  */
        .AddTransient<IMySpecialObjectDomainData, MySpecialObjectEntityFrameworkDomainDataLayer>()
    .AddTransient<IMySpecialObjectManager, MySpecialObjectManager>()

    /* so the "ServiceLifetime.Transient" below................is what you will find most commonly on the internet search results */
     # if (MY_ORACLE)
        .AddDbContext<ProvisioningDbContext>(options => options.UseOracle(defaultConnectionStringValue), ServiceLifetime.Transient);
     # endif

     # if (MY_SQL_SERVER)
        .AddDbContext<ProvisioningDbContext>(options => options.UseSqlServer(defaultConnectionStringValue), ServiceLifetime.Transient);
     # endif

    servColl.AddSingleton <IMySpecialObjectThatSpawnsThreads,        MySpecialObjectThatSpawnsThreads>();

    ServiceProvider servProv = servColl.BuildServiceProvider();

    return servProv;
}

The ones that surprised me were the (change to) transient for

        .AddTransient<IMySpecialObjectDomainData, MySpecialObjectEntityFrameworkDomainDataLayer>()
    .AddTransient<IMySpecialObjectManager, MySpecialObjectManager>()

Note, I think because IMySpecialObjectManager was being injected into "MySpecialObjectThatSpawnsThreads", those injected objects needed to be Transient to complete the chain.

The point being.......it wasn't just the (My)DbContext that needed .Transient...but a bigger chunk of the DI Graph.

Debugging Tip:

This line:

this.entityDbContext = context ?? throw new ArgumentNullException("MyCoolDbContext is null", (Exception)null);

Put your debugger break point there. If your MySpecialObjectThatSpawnsThreads is making N number of threads (say 10 threads for example)......and that line is only being hit once...that's your issue. Your DbContext is crossing threads.

BONUS:

I would suggest reading this below url/article (oldie but goodie) about the differences web-apps and console-apps

I hit this issue with WorkFlowCore https://github.com/danielgerlag/workflow-core

  <ItemGroup>
    <PackageReference Include="WorkflowCore" Version="3.1.5" />
  </ItemGroup>

sample code below.. to help future internet searchers

            }
        }
    }

and

ICollection<string> workFlowGeneratedIds = new List<string>();
                for (int i = 0; i < 10; i++)
                {
                    MySpecialObjectInterviewPassThroughData currentMySpecialObjectInterviewPassThroughData = new MySpecialObjectInterviewPassThroughData();

                    workFlowGeneratedIds.Add(wfid);
                }

Try switching them:

return RedirectToAction("Account", "Login");

I tried it and it worked.

I couldn't figure out how to do this in pure MS LINQ, so I wrote my own extension method to do it:

public static bool In<T>(this T objToCheck, params T[] values)
{
    if (values == null || values.Length == 0) 
    {
        return false; //early out
    }
    else
    {
        foreach (T t in values)
        {
            if (t.Equals(objToCheck))
                return true;   //RETURN found!
        }

        return false; //nothing found
    }
}

Swift version of accepted answer:

func scrollViewDidScroll(scrollView: UIScrollView) {
     // example code
}
func scrollViewDidEndDragging(scrollView: UIScrollView, willDecelerate decelerate: Bool) {
        // example code
}
func scrollViewDidEndZooming(scrollView: UIScrollView, withView view: UIView!, atScale scale: CGFloat) {
      // example code
}

You should look at compareTo function of Date class.

JavaDoc

I coded up an equivalent C program to experiment, and I can confirm this strange behaviour. What's more, gcc believes the 64-bit integer (which should probably be a size_t anyway...) to be better, as using uint_fast32_t causes gcc to use a 64-bit uint.

I did a bit of mucking around with the assembly:
Simply take the 32-bit version, replace all 32-bit instructions/registers with the 64-bit version in the inner popcount-loop of the program. Observation: the code is just as fast as the 32-bit version!

This is obviously a hack, as the size of the variable isn't really 64 bit, as other parts of the program still use the 32-bit version, but as long as the inner popcount-loop dominates performance, this is a good start.

I then copied the inner loop code from the 32-bit version of the program, hacked it up to be 64 bit, fiddled with the registers to make it a replacement for the inner loop of the 64-bit version. This code also runs as fast as the 32-bit version.

My conclusion is that this is bad instruction scheduling by the compiler, not actual speed/latency advantage of 32-bit instructions.

(Caveat: I hacked up assembly, could have broken something without noticing. I don't think so.)

function scrollToBottom() {
     $("#mContainer").animate({ scrollTop: $("#mContainer")[0].scrollHeight }, 1000);
}

This is the solution work from me and you find, I'm sure

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

its super easy.

You'll need each machine to have it's own copy of ElasticSearch (simply copy the one you have now) -- the reason is that each machine / node whatever is going to keep it's own files that are sharded accross the cluster.

The only thing you really need to do is edit the config file to include the name of the cluster.

If all machines have the same cluster name elasticsearch will do the rest automatically (as long as the machines are all on the same network)

Read here to get you started: https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html

When you create indexes (where the data goes) you define at that time how many replicas you want (they'll be distributed around the cluster)

If you're looking for a particular string, put quotes around it:

awk '$1 == "findtext" {print $3}'

Otherwise, awk will assume it's a variable name.

A possible solution might be to use the JSON dumps() method, so you can convert the dictionary to a string ---

import json

a={"a":10, "b":20}
b={"b":20, "a":10}
c = [json.dumps(a), json.dumps(b)]


set(c)
json.dumps(a) in c

Output -

set(['{"a": 10, "b": 20}'])
True

The following command prints the total number of commits on the current branch.

git shortlog -s -n  | awk '{ sum += $1; } END { print sum; }' "$@"

It is made up of two parts:

1. Print the total logs number grouped by author (git shortlog -s -n)

   Example output

2. Sum up the total commit number of each author, i.e. the first argument of each line, and print the result out (awk '{ sum += $1; } END { print sum; }' "$@")

   Using the same example as above it will sum up 1445 + 1398 + 1376 + 166 + 166. Therefore the output will be:

     4,551
   

The example below will display a button with a title "Contact" on the navigation bar on the right. Its action calls a method named "contact" from the viewcontroller. Without this line the right button is not visible.

    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@"Contact"
                                                                          style:UIBarButtonItemStylePlain target:self action:@selector(contact:)];;

For ES6/ES2015 you can import directly like:

// example.json
{
    "name": "testing"
}


// ES6/ES2015
// app.js
import * as data from './example.json';
const word = data.name;
console.log(word); // output 'testing'

If you use typescript, you may declare json module like:

// tying.d.ts
declare module "*.json" {
    const value: any;
    export default value;
}

Thanks Aakash for recommending JIDE MultilineLabel. JIDE's StyledLabel is also enhanced recently to support multiple line. I would recommend it over the MultilineLabel as it has many other great features. You can check out an article on StyledLabel below. It is still free and open source.

http://www.jidesoft.com/articles/StyledLabel.pdf

You can use round function. Here some example

numpy.round([2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01],2)
array([ 21.53,   8.13,   3.97,  10.08])

IF you want change just display representation, I would not recommended to alter printing format globally, as it suggested above. I would format my output in place.

>>a=np.array([2.15295647e+01, 8.12531501e+00, 3.97113829e+00, 1.00777250e+01])
>>> print([ "{:0.2f}".format(x) for x in a ])
['21.53', '8.13', '3.97', '10.08']

Potential answer for SQL Server

Interesting I just ran a test using LinqPad with SQL Server which should be just running Linq to SQL underneath and it generates the following SQL statement.

Records .Where(r => r.Name.Contains("lkjwer--_~[]"))

-- Region Parameters
DECLARE @p0 VarChar(1000) = '%lkjwer--~_~~~[]%'
-- EndRegion
SELECT [t0].[ID], [t0].[Name]
FROM [RECORDS] AS [t0]
WHERE [t0].[Name] LIKE @p0 ESCAPE '~'

So I haven't tested it yet but it looks like potentially the ESCAPE '~' keyword may allow for automatic escaping of a string for use within a like expression.

PHP version > 5.0 has a nice SoapClient integrated. Which doesn't require to parse response xml. Here's a quick example

$client = new SoapClient("http://path.to/wsdl?WSDL");
$res = $client->SoapFunction(array('param1'=>'value','param2'=>'value'));
echo $res->PaymentNotification->payment;

Seems your selector is wrong, try using:

a.button:hover{
     background: #383;
}

Your code

a.button a:hover

Means it is going to search for an a element inside a with class button.

This is CLEANEST, SIMPLEST ANSWER for CONTIGUOUS NON-PRINTING Ruby Code:

The below also happens to answer the Original Poster's question without, the "ugly" conditional code that some commenters have mentioned.

1. CONTIGUOUS NON-PRINTING Ruby Code

   • This will work in any mixed language Rails View file, e.g, *.html.erb, *.js.erb, *.rhtml, etc.

   • This should also work with STD OUT/printing code, e.g. <%#= f.label :title %>

   • DETAILS:

     Rather than use rails brackets on each line and commenting in front of each starting bracket as we usually do like this:

       <%# if flash[:myErrors] %>
         <%# if flash[:myErrors].any? %>
           <%# if @post.id.nil? %>
             <%# if @myPost!=-1 %>
               <%# @post = @myPost %>
             <%# else %>
               <%# @post = Post.new %>
             <%# end %>
           <%# end %>
         <%# end %>
       <%# end %>
     

     YOU CAN INSTEAD add only one comment (hashmark/poundsign) to the first open Rails bracket if you write your code as one large block... LIKE THIS:

       <%# 
         if flash[:myErrors] then
           if flash[:myErrors].any? then
             if @post.id.nil? then
               if @myPost!=-1 then
                 @post = @myPost 
               else 
                 @post = Post.new 
               end 
             end 
           end 
         end 
       %>
     

The code below will change the div to blue.

<script>
 $(document).ready(function(){ 
   $("#co").click({
            $("body").css("background-color","blue");
      });
    }); 
</script>
<body>
      <div id="co">hello</div>
</body>

Some of the scenarios, object.item would not be loaded or will be undefined.

Use ng-init

<select ng-init="object.item=2" ng-model="object.item"
ng-options="item.id as item.name for item in list"

I got this error: "Type does not contain a definition for GetProperty" when tying the accepted answer.

This is what i ended up with:

using System.Reflection;

if (productModel.GetType().GetTypeInfo().GetDeclaredProperty(propertyName) != null)
{

}

The problem is that the 'and' is being treated as an 'or'.

No, the problem is that you are using the XPath != operator and you aren't aware of its "weird" semantics.

Solution:

Just replace the any x != y expressions with a not(x = y) expression.

In your specific case:

Replace:

<xsl:when test="$AccountNumber != '12345' and $Balance != '0'">

with:

<xsl:when test="not($AccountNumber = '12345') and not($Balance = '0')">

Explanation:

By definition whenever one of the operands of the != operator is a nodeset, then the result of evaluating this operator is true if there is a node in the node-set, whose value isn't equal to the other operand.

So:

 $someNodeSet != $someValue

generally doesn't produce the same result as:

 not($someNodeSet = $someValue)

The latter (by definition) is true exactly when there isn't a node in $someNodeSet whose string value is equal to $someValue.

Lesson to learn:

Never use the != operator, unless you are absolutely sure you know what you are doing.

I find the most readable way to express this is using a sql expression:

df.filter("my_date < date'2015-01-01'")

we can verify this works correctly by looking at the physical plan from .explain()

+- *(1) Filter (isnotnull(my_date#22) && (my_date#22 < 16436))

Give the table a class name and then you target the td's with the following:

table.classname td {
    font-size: 90%;
}

Try this. It will check to see if the file already exists in the destination folder, and if it does will check if the file is read-only. If the file is read-only it will change it to read-write, replace the file, and make it read-only again.

Const DestinationFile = "c:\destfolder\anyfile.txt"
Const SourceFile = "c:\sourcefolder\anyfile.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
    'Check to see if the file already exists in the destination folder
    If fso.FileExists(DestinationFile) Then
        'Check to see if the file is read-only
        If Not fso.GetFile(DestinationFile).Attributes And 1 Then 
            'The file exists and is not read-only.  Safe to replace the file.
            fso.CopyFile SourceFile, "C:\destfolder\", True
        Else 
            'The file exists and is read-only.
            'Remove the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
            'Replace the file
            fso.CopyFile SourceFile, "C:\destfolder\", True
            'Reapply the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
        End If
    Else
        'The file does not exist in the destination folder.  Safe to copy file to this folder.
        fso.CopyFile SourceFile, "C:\destfolder\", True
    End If
Set fso = Nothing

Old question, but I'd like to provide my own solution which turn out to be the fastest, use normal list instead of np.array as input (or transfer to list firstly), based on my bench test.

Check it out if you encounter it as well.

def count(a):
    results = {}
    for x in a:
        if x not in results:
            results[x] = 1
        else:
            results[x] += 1
    return results

For example,

>>>timeit count([1,1,1,2,2,2,5,25,1,1]) would return:

100000 loops, best of 3: 2.26 µs per loop

>>>timeit count(np.array([1,1,1,2,2,2,5,25,1,1]))

100000 loops, best of 3: 8.8 µs per loop

>>>timeit count(np.array([1,1,1,2,2,2,5,25,1,1]).tolist())

100000 loops, best of 3: 5.85 µs per loop

While the accepted answer would be slower, and the scipy.stats.itemfreq solution is even worse.

A more indepth testing did not confirm the formulated expectation.

from zmq import Stopwatch
aZmqSTOPWATCH = Stopwatch()

aDataSETasARRAY = ( 100 * abs( np.random.randn( 150000 ) ) ).astype( np.int )
aDataSETasLIST  = aDataSETasARRAY.tolist()

import numba
@numba.jit
def numba_bincount( anObject ):
    np.bincount(    anObject )
    return

Javac – compiler that converts source code to byte code. JVM- interpreter that converts byte code to machine language code.

As we know java is both compile**r & **interpreter based language. Once the java code also known as source code is compiled, it gets converted to native code known as BYTE CODE which is portable & can be easily executed on all operating systems. Byte code generated is basically represented in hexa decimal format. This format is same on every platform be it Solaris work station or Macintosh, windows or Linux. After compilation, the interpreter reads the generated byte code & translates it according to the host machine. . Byte code is interpreted by Java Virtual Machine which is available with all the operating systems we install. so to port Java programs to a new platform all that is required is to port the interpreter and some of the library routines.

Hope it helps!!!

Like this?

 System.out.println(Name + " " + Income);

I had similar issue with width property. I couldnt remove the !important from code, and since it needed this style on a new template I added an Id (modalstyling) to the element and afterwards i added following code to the template:

<script type="text/javascript">
    $('#modalstyling').css('width', '');    //Removal of width !important
    $('#modalstyling').width('75%');        //Set custom width
</script>

I found that I could access the checkbox directly using Worksheets("SheetName").CB_Checkboxname.value directly without relating to additional objects.

To me, Fresco is the best among the other libraries.

Just setup Fresco and then simply set the imageURI like this:

draweeView.setImageURI(uri);

Check out this answer explaining some of Fresco benefits.

I like this approach because it is simple and clean:

    String getCompaniesIdAndName = " select "
            + " c.id as id, "
            + " c.name as name "
            + " from Company c ";

    @Query(value = getCompaniesWithoutAccount)
    Set<CompanyIdAndName> findAllIdAndName();

    public static interface CompanyIdAndName extends DTO {
        Integer getId();

        String getName();

    }

This is due to a PHP 5.3.0 bug on Windows where MYSQL_ATTR_INIT_COMMAND is not available. The PHP bug report is:

http://bugs.php.net/bug.php?id=47224

If you are experiencing this, please update your WAMP product to a version that uses PHP 5.3.1 or later version.

Try

//*[text()='qwerty'] because . is your current element

Jar is ok, since there is compiled output in 'output' directory (project/out/production//)

I guess, you have to run 'make' before building jar

for dependencies just check "show library" and choose what you want.

Yep, you'll want to do something like this:

echo -n "Enter Fullname: " 
read fullname

Another option would be to have them supply this information on the command line. Getopts is your best bet there.

Using getopts in bash shell script to get long and short command line options

dplyr::as_data_frame(df, rownames = "your_row_name") will give you even simpler result.

You can using SXSSFWorkbook implementation of Workbook, if you use style in your excel ,You can caching style by Flyweight Pattern to improve your performance.

My own __init__.py files are empty more often than not. In particular, I never have a from blah import * as part of __init__.py -- if "importing the package" means getting all sort of classes, functions etc defined directly as part of the package, then I would lexically copy the contents of blah.py into the package's __init__.py instead and remove blah.py (the multiplication of source files does no good here).

If you do insist on supporting the import * idioms (eek), then using __all__ (with as miniscule a list of names as you can bring yourself to have in it) may help for damage control. In general, namespaces and explicit imports are good things, and I strong suggest reconsidering any approach based on systematically bypassing either or both concepts!-)

If you used managed wordpress or caching plugins, you have to CLEAR YOUR CACHE before the facebook debugger tool can fetch new info!

I've been pulling my hair out for weeks figuring out why changes I made wouldn't show up in facebook debugger for 24 hours!!!! The fix is I have to go into my wordpress dashboard, click the godaddy icon on the top, and click "flush cache." I think many managed wordpress hosters have a cache to figure out how to clear it and you'll be golden.

The solution here is to have different IDs as many of you have stated. The problem still lies deeper in datepicker. Please correct me, but doesn't the datepicker have one wrapper ID - "ui-datepicker-div." This is seen on http://jqueryui.com/demos/datepicker/#option-showOptions in the theming.

Is there an option that can change this ID to be a class? I don't want to have to fork this script just for this one obvious fix!!

With HTML5, you can do this natively with: <input name="first_name" placeholder="First Name">

This is not supported with all browsers though (IE)

This may work:

<input type="first_name" value="First Name" onfocus="this.value==this.defaultValue?this.value='':null">

Otherwise, if you are using jQuery, you can use .focus and .css to change the color.

You can also do this:

try {
     myView.getClass().getMethod(android.os.Build.VERSION.SDK_INT >= 16 ? "setBackground" : "setBackgroundDrawable", Drawable.class).invoke(myView, myBackgroundDrawable);
} catch (Exception ex) {
     // do nothing
}

EDIT: Just as pointed out by @BlazejCzapp it is preferable to avoid using reflection if you can manage to solve the problem without it. I had a use case where I was unable to solve without reflection but that is not case above. For more information please take a look at http://docs.oracle.com/javase/tutorial/reflect/index.html

if you are having a problem as describe in this post:

asp.net mvc debugger throwing SEHException

then the solution is:

if you have any application from Trusteer (like rapport or anything ) just uninstall and reboot your system, it'll work fine ... found this solution here:

filtered_list = [list_a[i] for i in range(len(list_a)) if filter[i]]

As of Chrome 46, a simple onclick=window.close() does the trick. This only closes the tab, and not the entire browser, if multiple tabs are opened.

Here's a solution if you're using React:

import * as React from 'react'
import { useDropzone } from 'react-dropzone'

function imageDropper() {
  const [imageUrl, setImageUrl] = React.useState()
  const [imageFile, setImageFile] = React.useState()

  const onDrop = React.useCallback(
    acceptedFiles => {
      const file = acceptedFiles[0]
      setImageFile(file)

      // convert file to data: url
      const reader = new FileReader()
      reader.addEventListener('load', () => setImageUrl(String(reader.result)), false)
      reader.readAsDataURL(file)
    },
    [setImageFile, setImageUrl]
  )
  const { getRootProps, getInputProps, isDragActive } = useDropzone({ onDrop })

  return (
    <div>
      <div {...getRootProps()}>
        {imageFile ? imageFile.name : ''}
        {isDragActive ? <p>Drop files here...</p> : <p>Select image file...</p>}
        <input {...getInputProps()} />
      </div>
      {imageUrl && (
        <div>
          Your image: <img src={imageUrl} />
        </div>
      )}
    </div>
  )
}

I had a similar issue only to observe that i had added the bootstrap script twice and the second bootstrap script was after above the jquery script.

Solution:

• Ensure that bootstrap.min.js and jquery.min.js are only included once in your file.
• The bootstrap.min.js script should be included after jquery.min.js

This is what I was looking for here:

declare -A hashmap
hashmap["key"]="value"
hashmap["key2"]="value2"
echo "${hashmap["key"]}"
for key in ${!hashmap[@]}; do echo $key; done
for value in ${hashmap[@]}; do echo $value; done
echo hashmap has ${#hashmap[@]} elements

This did not work for me with bash 4.1.5:

animals=( ["moo"]="cow" )

Try <input type="number" step="0.01" /> if you are targeting 2 decimal places :-).

Its simple

$(function() {
        $("#datePicker").datetimepicker({
            defaultDate:'now'

        });
    });

This will set today as default

Create your own custom IsEmpty TypeSafeMatcher:

Even if the generics problems are fixed in 1.3 the great thing about this method is it works on any class that has an isEmpty() method! Not just Collections!

For example it will work on String as well!

/* Matches any class that has an <code>isEmpty()</code> method
 * that returns a <code>boolean</code> */ 
public class IsEmpty<T> extends TypeSafeMatcher<T>
{
    @Factory
    public static <T> Matcher<T> empty()
    {
        return new IsEmpty<T>();
    }

    @Override
    protected boolean matchesSafely(@Nonnull final T item)
    {
        try { return (boolean) item.getClass().getMethod("isEmpty", (Class<?>[]) null).invoke(item); }
        catch (final NoSuchMethodException e) { return false; }
        catch (final InvocationTargetException | IllegalAccessException e) { throw new RuntimeException(e); }
    }

    @Override
    public void describeTo(@Nonnull final Description description) { description.appendText("is empty"); }
}

My project was created using Visual Studio Community 2017 and it creates 3 separated modules: app.browser.module, app.server.module and app.shared.module

In order to create my components I checked above answers and found my module to be app.shared.module.

So, I run:

ng g c componentName --module=app.shared.module

If you need to store UTF8 data in your database, you need a database that accepts UTF8. You can check the encoding of your database in pgAdmin. Just right-click the database, and select "Properties".

But that error seems to be telling you there's some invalid UTF8 data in your source file. That means that the copy utility has detected or guessed that you're feeding it a UTF8 file.

If you're running under some variant of Unix, you can check the encoding (more or less) with the file utility.

$ file yourfilename
yourfilename: UTF-8 Unicode English text

(I think that will work on Macs in the terminal, too.) Not sure how to do that under Windows.

If you use that same utility on a file that came from Windows systems (that is, a file that's not encoded in UTF8), it will probably show something like this:

$ file yourfilename
yourfilename: ASCII text, with CRLF line terminators

If things stay weird, you might try to convert your input data to a known encoding, to change your client's encoding, or both. (We're really stretching the limits of my knowledge about encodings.)

You can use the iconv utility to change encoding of the input data.

iconv -f original_charset -t utf-8 originalfile > newfile

You can change psql (the client) encoding following the instructions on Character Set Support. On that page, search for the phrase "To enable automatic character set conversion".

You are not changing the object in the assignment statement, you replace one immutable object with another one. Object String("a") does not change to String("ty"), it gets discarded, and a reference to ty gets written into a in its stead.

In contrast, StringBuffer represents a mutable object. You can do this:

StringBuffer b = new StringBuffer("Hello");
System.out.writeln(b);
b.append(", world!");
System.out.writeln(b);

Here, you did not re-assign b: it still points to the same object, but the content of that object has changed.

It depends on your Linux distibution and your preference of editors etc. but I would recommend to start with Kile (a KDE app) as it is easy to learn and installing it should install most of the needed packages for LaTex and PDF generation. Just have a look at the screenshots.

There are already a lot of answers but here is another approach if you're in the Rails world:

 cities = ["Kathmandu", "Pokhara", "", "Dharan", "Butwal"].select &:present?

- (CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
   return 45.0f; 
//set height according to row or section , whatever you want to do!
}

section label text are set.

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *sectionHeaderView;

        sectionHeaderView = [[UIView alloc] initWithFrame:
                             CGRectMake(0, 0, tableView.frame.size.width, 120.0)];


    sectionHeaderView.backgroundColor = kColor(61, 201, 247);

    UILabel *headerLabel = [[UILabel alloc] initWithFrame:
                            CGRectMake(sectionHeaderView.frame.origin.x,sectionHeaderView.frame.origin.y - 44, sectionHeaderView.frame.size.width, sectionHeaderView.frame.size.height)];

    headerLabel.backgroundColor = [UIColor clearColor];
    [headerLabel setTextColor:kColor(255, 255, 255)];
    headerLabel.textAlignment = NSTextAlignmentCenter;
    [headerLabel setFont:kFont(20)];
    [sectionHeaderView addSubview:headerLabel];

    switch (section) {
        case 0:
            headerLabel.text = @"Section 1";
            return sectionHeaderView;
            break;
        case 1:
            headerLabel.text = @"Section 2";
            return sectionHeaderView;
            break;
        case 2:
            headerLabel.text = @"Section 3";
            return sectionHeaderView;
            break;
        default:
            break;
    }

    return sectionHeaderView;
}

Its an old question I know but I did stumble across it so for future reference you can now do this:

pip uninstall [options] <package> ...
pip uninstall [options] -r <requirements file> ...

-r, --requirement file

Uninstall all the packages listed in the given requirements file. This option can be used multiple times.

from the pip documentation version 8.1

You're being a little confusing. I dont' know if you're mixing up some concepts.

You don't have a virtual base class in your OP. You just have a base class.

You did virtual inheritance. This is usually used in multiple inheritance so that multiple derived classes use the members of the base class without reproducing them.

A base class with a pure virtual function is not be instantiated. this requires the syntax that Paul gets at. It is typically used so that derived classes must define those functions.

I don't want to explain any more about this because I don't totally get what you're asking.

You shouldn't use flag e (or eval in general).

You can also use T-Regx library

pattern('(^|_)([a-z])')->replace($word)->by()->group(2)->callback('strtoupper');

            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            button1_Click(button1, new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 1, 1, 1, 1));

            //by the way
            //button1.PerformClick();
            // and
            //button1_Click(button1, new EventArgs());
            // are the same
        }

        private void button1_Click(object sender, EventArgs e)
        {
            MessageBox.Show("clicked");
        }
    }
}

Since you want to pivot multiple columns of data, I would first suggest unpivoting the result, score and grade columns so you don't have multiple columns but you will have multiple rows.

Depending on your version of SQL Server you can use the UNPIVOT function or CROSS APPLY. The syntax to unpivot the data will be similar to:

select ratio, col, value
from GRAND_TOTALS
cross apply
(
  select 'result', cast(result as varchar(10)) union all
  select 'score', cast(score as varchar(10)) union all
  select 'grade', grade
) c(col, value)

See SQL Fiddle with Demo. Once the data has been unpivoted, then you can apply the PIVOT function:

select ratio = col,
  [current ratio], [gearing ratio], [performance ratio], total
from
(
  select ratio, col, value
  from GRAND_TOTALS
  cross apply
  (
    select 'result', cast(result as varchar(10)) union all
    select 'score', cast(score as varchar(10)) union all
    select 'grade', grade
  ) c(col, value)
) d
pivot
(
  max(value)
  for ratio in ([current ratio], [gearing ratio], [performance ratio], total)
) piv;

See SQL Fiddle with Demo. This will give you the result:

|  RATIO | CURRENT RATIO | GEARING RATIO | PERFORMANCE RATIO |     TOTAL |
|--------|---------------|---------------|-------------------|-----------|
|  grade |          Good |          Good |      Satisfactory |      Good |
| result |       1.29400 |       0.33840 |           0.04270 |    (null) |
|  score |      60.00000 |      70.00000 |          50.00000 | 180.00000 |

You can have only one default export which you declare like:

export default App; or export default class App extends React.Component {...

and later do import App from './App'

If you want to export something more you can use named exports which you declare without default keyword like:

export {
  About,
  Contact,
}

or:

export About;
export Contact;

or:

export const About = class About extends React.Component {....
export const Contact = () => (<div> ... </div>);

and later you import them like:

import App, { About, Contact } from './App';

EDIT:

There is a mistake in the tutorial as it is not possible to make 3 default exports in the same main.js file. Other than that why export anything if it is no used outside the file?. Correct main.js :

import React from 'react';
import ReactDOM from 'react-dom';
import { Router, Route, Link, browserHistory, IndexRoute  } from 'react-router'

class App extends React.Component {
...
}

class Home extends React.Component {
...
}


class About extends React.Component {
...
}


class Contact extends React.Component {
...
}


ReactDOM.render((
   <Router history = {browserHistory}>
      <Route path = "/" component = {App}>
         <IndexRoute component = {Home} />
         <Route path = "home" component = {Home} />
         <Route path = "about" component = {About} />
         <Route path = "contact" component = {Contact} />
      </Route>
   </Router>

), document.getElementById('app'))

EDIT2:

another thing is that this tutorial is based on react-router-V3 which has different api than v4.

The answer to this question is saying to use display:none and display:block, but this does not help for someone who is trying to use css transitions to show and hide content using the visibility property.

This also drove me crazy, because using display kills any css transitions.

One solution is to add this to the class that's using visibility:

overflow:hidden

For this to work is does depend on the layout, but it should keep the empty content within the div it resides in.

I had this issue where I had already created the table and could not change it without dropping the table so what I did was: (Not sure when they implemented this but had it in SQL 2016)

Right click on the table in the Object Explorer:

Script Table as > DROP And CREATE To > New Query Editor Window

Then do the edit to the script said by Josien; scroll to the bottom where the CREATE TABLE is, find your Primary Key and append IDENTITY(1,1) to the end before the comma. Run script.

The DROP and CREATE script was also helpful for me because of this issue. (Which the generated script handles.)

<body topmargin="0" leftmargin="0" rightmargin="0">

I'm not sure where you read this, but this is the accepted way of setting CSS styles inline is:

<body style="margin-top: 0px; margin-left: 0px; margin-right: 0px;">

And with a stylesheet:

body
{
  margin-top: 0px;
  margin-left: 0px;
  margin-right: 0px;
}

Here my pack with all you need. Or you can use this script:

echo on
set device=emulator-5554
set avd_name=
set adb=d:\Poprygun\DevTools\Android\Android-sdk\platform-tools\adb -s %device%
set emulator=d:\Poprygun\DevTools\Android\Android-sdk\emulator\emulator
set arch=x86
set pie=

echo Close all ANDROID emulators and press any key
pause
start %emulator% -avd Nexus_One_API_25 -verbose -writable-system
echo Wait until ANDROID emulator loading and press any key
pause

%adb% start-server
%adb% root
%adb% remount
%adb% shell setenforce 0
%adb% install D:\SuperSU\SuperSU.apk

%adb% shell "su --daemon&"
pause
exit /b

I've played around with select items before and without overriding the functionality with JavaScript, I don't think it's possible in Chrome. Whether you use a plugin or write your own code, CSS only is a no go for Chrome/Safari and as you said, Firefox is better at dealing with it.

Doxygen creates inheritance diagrams but I dont think it will create an entire class hierachy. It does allow you to use the GraphViz tool. If you use the Doxygen GUI frontend tool you will find the relevant options in Step2: -> Wizard tab -> Diagrams. The DOT relation options are under the Expert Tab.

More readable way of achieving this (not a fan of single line ansible tasks)

- local_action: 
    module: copy 
    content: "{{ foo_result }}"
    dest: /path/to/destination/file

If you want your user to press enter, then the raw_input() will return "", so compare the User with "":

User = raw_input('Press enter to exit...')
running = 1
while running == 1:
    Run your program
if User == "":
    break
else
    running == 1

This example might be seem a bit lengthy, but its intention should be quite clear.

It uses 3 Boolean properties in the ViewModel called, FlagForValue1, FlagForValue2 and FlagForValue3. Each of these 3 properties is backed by a single private field called _intValue.

The 3 Radio buttons of the view (xaml) are each bound to its corresponding Flag property in the view model. This means the radio button displaying "Value 1" is bound to the FlagForValue1 bool property in the view model and the other two accordingly.

When setting one of the properties in the view model (e.g. FlagForValue1), its important to also raise property changed events for the other two properties (e.g. FlagForValue2, and FlagForValue3) so the UI (WPF INotifyPropertyChanged infrastructure) can selected / deselect each radio button correctly.

    private int _intValue;

    public bool FlagForValue1
    {
        get
        {
            return (_intValue == 1) ? true : false;
        }
        set
        {
            _intValue = 1;
            RaisePropertyChanged("FlagForValue1");
            RaisePropertyChanged("FlagForValue2");
            RaisePropertyChanged("FlagForValue3");
        }
    }

    public bool FlagForValue2
    {
        get
        {
            return (_intValue == 2) ? true : false;
        }
        set
        {
            _intValue = 2;
            RaisePropertyChanged("FlagForValue1");
            RaisePropertyChanged("FlagForValue2");
            RaisePropertyChanged("FlagForValue3");
        }
    }

    public bool FlagForValue3
    {
        get
        {
            return (_intValue == 3) ? true : false;
        }
        set
        {
            _intValue = 3;
            RaisePropertyChanged("FlagForValue1");
            RaisePropertyChanged("FlagForValue2");
            RaisePropertyChanged("FlagForValue3");
        }
    }

The xaml looks like this:

                <RadioButton GroupName="Search" IsChecked="{Binding Path=FlagForValue1, Mode=TwoWay}"
                             >Value 1</RadioButton>

                <RadioButton GroupName="Search" IsChecked="{Binding Path=FlagForValue2, Mode=TwoWay}"
                             >Value 2</RadioButton>

                <RadioButton GroupName="Search" IsChecked="{Binding Path=FlagForValue3, Mode=TwoWay}"
                             >Value 3</RadioButton>

zeros=[0]*4

you can replace 4 in the above example with whatever number you want.

I've found Waldo!

How I've done it

First, I'm filtering out all colours that aren't red

waldo = Import["http://www.findwaldo.com/fankit/graphics/IntlManOfLiterature/Scenes/DepartmentStore.jpg"];
red = Fold[ImageSubtract, #[[1]], Rest[#]] &@ColorSeparate[waldo];

Next, I'm calculating the correlation of this image with a simple black and white pattern to find the red and white transitions in the shirt.

corr = ImageCorrelate[red, 
   Image@Join[ConstantArray[1, {2, 4}], ConstantArray[0, {2, 4}]], 
   NormalizedSquaredEuclideanDistance];

I use Binarize to pick out the pixels in the image with a sufficiently high correlation and draw white circle around them to emphasize them using Dilation

pos = Dilation[ColorNegate[Binarize[corr, .12]], DiskMatrix[30]];

I had to play around a little with the level. If the level is too high, too many false positives are picked out.

Finally I'm combining this result with the original image to get the result above

found = ImageMultiply[waldo, ImageAdd[ColorConvert[pos, "GrayLevel"], .5]]

Use the Stopwatch class.

If you are working on linux/mac you can do this.

from subprocess import call

The primitive wrapper types are reference types that are automatically created behind the scenes whenever strings, num­bers, or Booleans are read.For example :

var name = "foo";
var firstChar = name.charAt(0);
console.log(firstChar);

This is what happens behind the scenes:

// what the JavaScript engine does
var name = "foo";
var temp = new String(name);
var firstChar = temp.charAt(0);
temp = null;
console.log(firstChar);

Because the second line uses a string (a primitive) like an object, the JavaScript engine creates an instance of String so that charAt(0) will work.The String object exists only for one statement before it’s destroyed check this

The instanceof operator returns false because a temporary object is created only when a value is read. Because instanceof doesn’t actually read anything, no temporary objects are created, and it tells us the ­values aren’t instances of primitive wrapper types. You can create primitive wrapper types manually

To handle sortable list in Framework7 when user release currently sorting element in new position, you can use this code:

  $$('li').on('sortable:sort',function(event){
    alert("From " + event.detail.startIndex + " to " + event.detail.newIndex);
  });

I guess you could use curl and wget, but since Oracle requires you to check of some checkmarks this will be painfull to emulate with the tools mentioned. You would have to download the page with the license agreement and from looking at it figure out what request is needed to get to the actual download.

Of course you could simply start a browser, but this might not qualify as 'from the command line'. So you might want to look into lynx, a text based browser.

You can do this by creating a constraint and connecting it via interface builder

See explanation: Auto_Layout_Constraints_in_Interface_Builder

raywenderlich beginning-auto-layout

AutolayoutPG Articles constraint Fundamentals

@interface ViewController : UIViewController {
    IBOutlet NSLayoutConstraint *leadingSpaceConstraint;
    IBOutlet NSLayoutConstraint *topSpaceConstraint;
}
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *leadingSpaceConstraint;

connect this Constraint outlet with your sub views Constraint or connect super views Constraint too and set it according to your requirements like this

 self.leadingSpaceConstraint.constant = 10.0;//whatever you want to assign

I hope this clarifies it.

In Angular 5

you can just say

this.http.get<Example>('assets/example.json')

This will give you Observable<Example>

scp -r C:/site user@server_ip:path

path is the place, where site will be copied into the remote server

EDIT: As I said in my comment, try pscp, as you want to use scp using PuTTY.

The other option is WinSCP

MySQL INFORMATION_SCHEMA.TABLES table contains data about both tables (not temporary but permanent ones) and views. The column TABLE_TYPE defines whether this is record for table or view (for tables TABLE_TYPE='BASE TABLE' and for views TABLE_TYPE='VIEW'). So if you want to see from your schema (database) tables only there's the following query :

SELECT *
FROM information_schema.tables
WHERE table_type='BASE TABLE'
AND table_schema='myschema'

List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");

//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));

//Output : C
items.forEach(item->{
    System.out.println(item);
    System.out.println(item.toLowerCase());
  }
});

Code above didn't return correct result on my linux because winsize-struct has 4 unsigned shorts, not 2 signed shorts:

def terminal_size():
    import fcntl, termios, struct
    h, w, hp, wp = struct.unpack('HHHH',
        fcntl.ioctl(0, termios.TIOCGWINSZ,
        struct.pack('HHHH', 0, 0, 0, 0)))
    return w, h

hp and hp should contain pixel width and height, but don't.

You need to do something like this (If you want to call the method on page load):

new Vue({
    // ...
    methods:{
        getUnits: function() {...}
    },
    created: function(){
        this.getUnits()
    }
});

If the HTMLElement is input[type='button'], input[type='submit'], etc.

<input id="ShowButton" type="button" value="Show">
<input id="ShowButton" type="submit" value="Show">

change it using this code:

document.querySelector('#ShowButton').value = 'Hide';

If, the HTMLElement is button[type='button'], button[type='submit'], etc:

<button id="ShowButton" type="button">Show</button>
<button id="ShowButton" type="submit">Show</button>

change it using any of these methods,

document.querySelector('#ShowButton').innerHTML = 'Hide';
document.querySelector('#ShowButton').innerText = 'Hide';
document.querySelector('#ShowButton').textContent = 'Hide';

Please note that

• input is an empty tag and cannot have innerHTML, innerText or textContent
• button is a container tag and can have innerHTML, innerText or textContent

Ignore this answer if you ain't using asp.net-web-forms, asp.net-ajax and rad-grid

You must use value instead of innerHTML.

Try this.

document.getElementById("ShowButton").value= "Hide Filter";

And since you are running the button at server the ID may get mangled in the framework. I so, try

document.getElementById('<%=ShowButton.ClientID %>').value= "Hide Filter";

Another better way to do this is like this.

On markup, change your onclick attribute like this. onclick="showFilterItem(this)"

Now use it like this

function showFilterItem(objButton) {
    if (filterstatus == 0) {
        filterstatus = 1;
        $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().showFilterItem();
        objButton.value = "Hide Filter";
    }
    else {
        filterstatus = 0;
        $find('<%=FileAdminRadGrid.ClientID %>').get_masterTableView().hideFilterItem();
        objButton.value = "Show filter";
    }
}

 SqlConnection connection = new SqlConnection(ConnectionString);

 command = new SqlCommand("TestProcedure", connection);
 command.CommandType = System.Data.CommandType.StoredProcedure;

 connection.Open();

 DataTable dt = new DataTable();

 dt.Load(command.ExecuteReader());

 gvGrid.DataSource = dt;
 gvGrid.DataBind();

$('#checkbox').prop('checked', true);

When you want it unchecked:

$('#checkbox').prop('checked', false);

This was an enormously helpful link to find:

http://php.net/manual/en/migration56.openssl.php

An official document describing the changes made to open ssl in PHP 5.6 From here I learned of one more parameter I should have set to false: "verify_peer_name"=>false

Note: This has very significant security implications. Disabling verification potentially permits a MITM attacker to use an invalid certificate to eavesdrop on the requests. While it may be useful to do this in local development, other approaches should be used in production.

So my working code looks like this:

<?php
$arrContextOptions=array(
    "ssl"=>array(
        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ),
);

echo $response; ?>

use

with the range F4:G9:

0   0.1
1   0.15
5   0.2
15  0.3
30  1
100 1.3

and D4 being the value in question, e.g. 18.75 -> result: 0.3

You want to call .name on the object's class:

result.class.name

struct A {};
struct B : A {};
struct C {}; 

int main()
{
    A* a = new A;    

    int i = 10;

    a = (A*) (&i); // NO ERROR! FAIL!

    //a = static_cast<A*>(&i); ERROR! SMART!

    A* b = new B;

    B* b2 = static_cast<B*>(b); // NO ERROR! SMART!

    C* c = (C*)(b); // NO ERROR! FAIL!

    //C* c = static_cast<C*>(b); ERROR! SMART!
}

This is not an answer to your original question: "Appending output of a Batch file To log file?"

For reference, it's an answer to your followup question: "What lines should i add to my batch file which will make it execute after every 30mins?"

(But I would take Jon Skeet's advice: "You probably shouldn't do that in your batch file - instead, use Task Scheduler.")

Timeout:

• timeout command 1
• timeout command 2

Example (1 second):

TIMEOUT /T 1000 /NOBREAK

Sleep:

• sleep command (if sleep.exe is installed)

Example (1 second):

sleep -m 1000

Alternative methods:

• Sleeping in a batch file
• batch script, put to sleep until certain time

Here's an answer to your 2nd followup question: "Along with the Timestamp?"

Create a date and time stamp in your batch files

Example:

echo *** Date: %DATE:/=-% and Time:%TIME::=-% *** >> output.log

Or even just:

<div id="full-size">
  Your contents go here
</div>

html,body{ margin:0; padding:0; height:100%; width:100%; }
#full-size{
  height:100%;
  width:100%;
  overflow:hidden; /* or overflow:auto; if you want scrollbars */
}

(html, body can be set to like.. 95%-99% or some such to account for slight inconsistencies in margins, etc.)

After installing Free BitDefender AntiVirus the services related to the AntiVirus used about 80 MB of my computer's Memory. I also noticed that after installing BitDefender the service related to windows Presentation Font Cache was also installed: "WPFFontCache_v0300.exe". I disabled the service from stating automatically and now BitDefender Free AntiVirus use only 15-20 MB (!!!) of my computer's Memory! As far as I concern, this service affected negatively the memory usage of my PC inother services. I recommend you to disable it.

Go to the folder in which you have Node and NPM (such as C:\Program Files (x86)\nodejs\) and type the following:

Using ES6 syntax in React does not bind this to user-defined functions however it will bind this to the component lifecycle methods.

So the function that you declared will not have the same context as the class and trying to access this will not give you what you are expecting.

For getting the context of class you have to bind the context of class to the function or use arrow functions.

Method 1 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.onMove = this.onMove.bind(this);
        this.testVarible= "this is a test";
    }

    onMove() {
        console.log(this.testVarible);
    }
}

Method 2 to bind the context:

class MyContainer extends Component {

    constructor(props) {
        super(props);
        this.testVarible= "this is a test";
    }

    onMove = () => {
        console.log(this.testVarible);
    }
}

Method 2 is my preferred way but you are free to choose your own.

Update: You can also create the properties on class without constructor:

class MyContainer extends Component {

    testVarible= "this is a test";

    onMove = () => {
        console.log(this.testVarible);
    }
}

Note If you want to update the view as well, you should use state and setState method when you set or change the value.

Example:

class MyContainer extends Component {

    state = { testVarible: "this is a test" };

    onMove = () => {
        console.log(this.state.testVarible);
        this.setState({ testVarible: "new value" });
    }
}

From Oracle (but works in most SQL DBs):

SELECT LASTNAME, COUNT(*)
FROM STUDENTS
GROUP BY LASTNAME
HAVING COUNT(*) >= 3

P.S. it's faster one, because you have no Select withing Select methods here

You can install pip (or any other package) with easy_install almost as described in the first answer. However you will need a HTTPS proxy, too. The full sequence of commands is:

set http_proxy=http://proxy.myproxy.com
set https_proxy=http://proxy.myproxy.com
easy_install pip

You might also want to add a port to the proxy, such as http{s}_proxy=http://proxy.myproxy.com:8080

Maybe you can use pandas crosstab function

test5 = pd.crosstab(index=faultdf['Site Name'], columns=faultdf[''Abuse/NFF''])

test5.plot(kind='bar', stacked=True)

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

Using interactive rebase, you can place an amend command after each commit you want to alter. For instance:

pick a07cb86 Project tile template with full details and styling
x git commit --amend --reset-author -Chead

Use:

select * from mytest
EXEC sp_rename 'mytest.eid', 'id', 'COLUMN'
alter table mytest add id int not null identity(1,1)
update mytset set eid=id
ALTER TABLE mytest DROP COLUMN eid

ALTER TABLE [dbo].[yourtablename] ADD DEFAULT (getdate()) FOR [yourfieldname]

It's working 100%.

Change this property and try this at design time:

FormBorderStyle = FormBorderStyle.FixedDialog;

Here is something else I found:

1. After I have the "prefs" URL Scheme defined, "prefs:root=Safari&path=ContentBlockers" is working on Simulator (iOS 9.1 English), but not working on Simulator (Simplified Chinese). It just jump to Safari, but not Content Blockers. If your app is international, be careful.
   Update: Don't know why, now I can't jump into ContentBlockers anymore, the same code, the same version, doesn't work now. :(

2. On real devcies (mine is iPhone 6S & iPad mini 2), "Safari" should be "SAFARI", "Safari" not working on real device, "SAFARI" now working on simulator:

   #if arch(i386) || arch(x86_64)
       // Simulator
       let url = NSURL(string: "prefs:root=Safari")!

Can also export functions from dll and import from the exe, it is more tricky at first but in the end is much easier than calling LoadLibrary/GetProcAddress. See MSDN.

When creating the project with the VS wizard there's a check box in the dll that let you export functions.

Then, in the exe application you only have to #include a header from the dll with the proper definitions, and add the dll project as a dependency to the exe application.

Check this other question if you want to investigate this point further Exporting functions from a DLL with dllexport.

Try this one:

$this->db->select("*");
$this->db->where_in("(SELECT trans_id FROM myTable WHERE code = 'B')");
$this->db->where('code !=', 'B');
$this->db->get('myTable');

Note: $this->db->select("*"); is optional when you are selecting all columns from table

If you attempt to commit, and if there are conflicts, then git will give you the list of the currently unresolved conflicts... but not as a plain list. This is usually what you want when working interactively because the list gets shorter as you fix the conflicts.

is null is the syntax I use for such things, when COALESCE is of no help.

Try:

if (@zipCode is null)
  begin
    ([Portal].[dbo].[Address].Position.Filter(@radiusBuff) = 1)   
  end
else 
  begin
    ([Portal].[dbo].[Address].PostalCode=@zipCode )
  end  

Does the user you're executing this script under even see that table??

select top 1 * from products

Do you get any output for this??

If yes: does this user have the permission to modify the table, i.e. execute DDL scripts like ALTER TABLE etc.? Typically, regular users don't have this elevated permissions.

The javadoc for setParameter(String, Object) is explicit, saying that the Object value must be non-null. It's a shame that it doesn't throw an exception if a null is passed in, though.

An alternative is setParameter(String, Object, Type), which does allow null values, although I'm not sure what Type parameter would be most appropriate here.

The other way to tackle it is to use this code snippet:

JSON.parse(JSON.stringify(response)).data

This feels so wrong but it works

UPDATE

This was an old answer. Nowadays you should just use click. For more advanced event firing, use dispatchEvent.

const body = document.body;_x000D_
_x000D_
body.addEventListener('click', e => {_x000D_
  console.log('clicked body');_x000D_
});_x000D_
_x000D_
console.log('Using click()');_x000D_
body.click();_x000D_
_x000D_
console.log('Using dispatchEvent');_x000D_
body.dispatchEvent(new Event('click'));

Original Answer

Here is what I use: http://jsfiddle.net/mendesjuan/rHMCy/4/

Updated to work with IE9+

/**
 * Fire an event handler to the specified node. Event handlers can detect that the event was fired programatically
 * by testing for a 'synthetic=true' property on the event object
 * @param {HTMLNode} node The node to fire the event handler on.
 * @param {String} eventName The name of the event without the "on" (e.g., "focus")
 */
function fireEvent(node, eventName) {
    // Make sure we use the ownerDocument from the provided node to avoid cross-window problems
    var doc;
    if (node.ownerDocument) {
        doc = node.ownerDocument;
    } else if (node.nodeType == 9){
        // the node may be the document itself, nodeType 9 = DOCUMENT_NODE
        doc = node;
    } else {
        throw new Error("Invalid node passed to fireEvent: " + node.id);
    }

     if (node.dispatchEvent) {
        // Gecko-style approach (now the standard) takes more work
        var eventClass = "";

        // Different events have different event classes.
        // If this switch statement can't map an eventName to an eventClass,
        // the event firing is going to fail.
        switch (eventName) {
            case "click": // Dispatching of 'click' appears to not work correctly in Safari. Use 'mousedown' or 'mouseup' instead.
            case "mousedown":
            case "mouseup":
                eventClass = "MouseEvents";
                break;

            case "focus":
            case "change":
            case "blur":
            case "select":
                eventClass = "HTMLEvents";
                break;

            default:
                throw "fireEvent: Couldn't find an event class for event '" + eventName + "'.";
                break;
        }
        var event = doc.createEvent(eventClass);
        event.initEvent(eventName, true, true); // All events created as bubbling and cancelable.

        event.synthetic = true; // allow detection of synthetic events
        // The second parameter says go ahead with the default action
        node.dispatchEvent(event, true);
    } else  if (node.fireEvent) {
        // IE-old school style, you can drop this if you don't need to support IE8 and lower
        var event = doc.createEventObject();
        event.synthetic = true; // allow detection of synthetic events
        node.fireEvent("on" + eventName, event);
    }
};

Note that calling fireEvent(inputField, 'change'); does not mean it will actually change the input field. The typical use case for firing a change event is when you set a field programmatically and you want event handlers to be called since calling input.value="Something" won't trigger a change event.

First, ensure that your version of Eclipse and JDK match, either both 64-bit or both 32-bit (you can't mix-and-match 32-bit with 64-bit).

Second, the -vm argument in eclipse.ini should point to the java executable. See http://wiki.eclipse.org/Eclipse.ini for examples.

If you're unsure of what version (64-bit or 32-bit) of Eclipse you have installed, you can determine that a few different ways. See How to find out if an installed Eclipse is 32 or 64 bit version?

If you use org.junit.Assert a lot, you might find some value to adding it there.

The problem might be with the Movie format. If it's H264 encoded, make sure it's in baseline profile.

This is plain Javascript and has nothing to do with the jQuery library.

You simply escape the apostrophe with a backslash:

theAnchorText = 'I\'m home';

Another alternative is to use quotation marks around the string, then you don't have to escape apostrophes:

theAnchorText = "I'm home";

Jersey makes the process very easy, my service class worked well with JSON, all I had to do is to add the dependencies in the pom.xml

@Path("/customer")
public class CustomerService {

    private static Map<Integer, Customer> customers = new HashMap<Integer, Customer>();

    @POST
    @Path("save")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public SaveResult save(Customer c) {

        customers.put(c.getId(), c);

        SaveResult sr = new SaveResult();
        sr.sucess = true;
        return sr;
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    @Path("{id}")
    public Customer getCustomer(@PathParam("id") int id) {
        Customer c = customers.get(id);
        if (c == null) {
            c = new Customer();
            c.setId(id * 3);
            c.setName("unknow " + id);
        }
        return c;
    }
}

Actually it's possible, despite what's being said in other answers. If you have a FrameLayout, and want to position a child item to the bottom, you can use android:layout_gravity="bottom" and that is going to align that child to the bottom of the FrameLayout.

I know it works because I'm using it. I know is late, but it might come handy to others since this ranks in the top positions on google

use "x".ord for a single character or "xyz".sum for a whole string.

Another spin on this topic. The below script displays a few days around the current, with day-of-week prefix.

At the core is the standalone :dpack routine that encodes the date into a value whose modulo 7 reveals the day-of-week per ISO 8601 standards (Mon == 0). Also provided is :dunpk which is the inverse function:

@echo off& setlocal enabledelayedexpansion
rem 10/23/2018 daydate.bat: Most recent version at paulhoule.com/daydate
rem Example of date manipulation within a .BAT file.
rem This is accomplished by first packing the date into a single number.
rem This demo .bat displays dates surrounding the current date, prefixed
rem with the day-of-week.

  set /a dow=od%%7
  for %%d in (!dow!) do set day=!days:*%%d=!& set day=!day:~,3!
  echo !day! !y! !m! !d!
)
exit /b

Note that the first quotation mark goes before the leading \ and the second goes after the end of the folder name.

I hope this will suffice:

using System;
                
public class Program
{
    public static void Main()
    {
        //Example using word cat
        permute("cat");
    
    }

static void permute(string word){
    for(int i=0; i < word.Length; i++){
        char start = word[0];
        for(int j=1; j < word.Length; j++){
            string left = word.Substring(1,j-1);
            string right = word.Substring(j);
            Console.WriteLine(start+right+left);
        }
        if(i+1 < word.Length){
            word = wordChange(word, i + 1);
        }
            
    }
}

static string wordChange(string word, int index){
    string newWord = "";
    for(int i=0; i<word.Length; i++){
        if(i== 0)
            newWord += word[index];
        else if(i== index)
            newWord += word[0];
        else
            newWord += word[i];
    }
    return newWord;
}

output:

You can also check like struct_var == (struct{}). This does not allow you to compare to nil but it does check if it is initialized or not. Be careful while using this method. If your struct can have zero values for all of its fields you won't have great time.

package main

import "fmt"

type A struct {
    Name string
}

func main() {
    a := A{"Hello"}
    var b A

    if a == (A{}) {
        fmt.Println("A is empty") // Does not print
    } 

    if b == (A{}) {
        fmt.Println("B is empty") // Prints
    } 
}

I know this question got great answers already but I wish to add the following method using numpy.

temp2 = ['One', 'Two']

list(np.setdiff1d(temp1,temp2))

['Four', 'Three'] #Output

If you want to use the image as a CSS background, there is an elegant solution. Simply use cover or contain in the background-size CSS3 property.

.container {_x000D_
  width: 150px;_x000D_
  height: 100px;_x000D_
  background-image: url("http://i.stack.imgur.com/2OrtT.jpg");_x000D_
  background-size: cover;_x000D_
  background-repeat: no-repeat;_x000D_
  background-position: 50% 50%;_x000D_
}

<div class="container"></div>?

While cover will give you a scaled up image, contain will give you a scaled down image. Both will preserve the pixel aspect ratio.

This approach has the advantage of being friendly to Retina displays as per Thomas Fuchs' quick guide.

It's worth mentioning that browser support for both attributes excludes IE6-8.

Include required imports and you can make ur decision in handleError method Error status will give the error code

import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import {Observable, throwError} from "rxjs/index";
import { catchError, retry } from 'rxjs/operators';
import {ApiResponse} from "../model/api.response";
import { TaxType } from '../model/taxtype.model'; 

private handleError(error: HttpErrorResponse) {
if (error.error instanceof ErrorEvent) {
  // A client-side or network error occurred. Handle it accordingly.
  console.error('An error occurred:', error.error.message);
} else {
  // The backend returned an unsuccessful response code.
  // The response body may contain clues as to what went wrong,
  console.error(
    `Backend returned code ${error.status}, ` +
    `body was: ${error.error}`);
}
// return an observable with a user-facing error message
return throwError(
  'Something bad happened; please try again later.');
  };

  getTaxTypes() : Observable<ApiResponse> {
return this.http.get<ApiResponse>(this.baseUrl).pipe(
  catchError(this.handleError)
);
  }

So to start with some kind of answer : ) - You can't

I am not an expert, but as far as I understand DataFrames, they are not equal to rdd and DataFrame has no such thing as Partitioner.

Generally DataFrame's idea is to provide another level of abstraction that handles such problems itself. The queries on DataFrame are translated into logical plan that is further translated to operations on RDDs. The partitioning you suggested will probably be applied automatically or at least should be.

If you don't trust SparkSQL that it will provide some kind of optimal job, you can always transform DataFrame to RDD[Row] as suggested in of the comments.

Final keyword has a numerous way to use:

• A final class cannot be subclassed.
• A final method cannot be overridden by subclasses
• A final variable can only be initialized once

Other usage:

• When an anonymous inner class is defined within the body of a method, all variables declared final in the scope of that method are accessible from within the inner class

A static class variable will exist from the start of the JVM, and should be initialized in the class. The error message won't appear if you do this.

I know this is a little old but I wanted to add an updated answer with f-strings which were introduced in Python version 3.6:

msg['Subject'] = f'Auto Hella Restart Report {sys.argv[1]}'

So what does count_votes look like? Is it a script? Anything that you want to get back from an ajax call can be retrieved using a simple echo (of course you could use JSON or xml, but for this simple example you would just need to output something in count_votes.php like:

$id = $_POST['id'];

function getVotes($id){
    // call your database here
    $query = ("SELECT votes FROM poll WHERE ID = $id");
    $result = @mysql_query($query);
    $row = mysql_fetch_row($result);

    return $row->votes;
}
$votes = getVotes($id);
echo $votes;

This is just pseudocode, but should give you the idea. What ever you echo from count_votes will be what is returned to "data" in your ajax call.

Here is a sample helper class which converts an Object and returns an Expando with all public properties of the given object.

    public static class dynamicHelper
        {
            public static ExpandoObject convertToExpando(object obj)
            {
                //Get Properties Using Reflections
                BindingFlags flags = BindingFlags.Public | BindingFlags.Instance;
                PropertyInfo[] properties = obj.GetType().GetProperties(flags);

                //Add Them to a new Expando
                ExpandoObject expando = new ExpandoObject();
                foreach (PropertyInfo property in properties)
                {
                    AddProperty(expando, property.Name, property.GetValue(obj));
                }

                return expando;
            }

            public static void AddProperty(ExpandoObject expando, string propertyName, object propertyValue)
            {
                //Take use of the IDictionary implementation
                var expandoDict = expando as IDictionary;
                if (expandoDict.ContainsKey(propertyName))
                    expandoDict[propertyName] = propertyValue;
                else
                    expandoDict.Add(propertyName, propertyValue);
            }
        }

Usage:

//Create Dynamic Object
dynamic expandoObj= dynamicHelper.convertToExpando(myObject);

//Add Custom Properties
dynamicHelper.AddProperty(expandoObj, "dynamicKey", "Some Value");

For those people still arriving at this question in 2020 or later, there are newer options that may be better than both of these. For example, utf8mb4_0900_ai_ci.

All these collations are for the UTF-8 character encoding. The differences are in how text is sorted and compared.

_unicode_ci and _general_ci are two different sets of rules for sorting and comparing text according to the way we expect. Newer versions of MySQL introduce new sets of rules, too, such as _0900_ai_ci for equivalent rules based on Unicode 9.0 - and with no equivalent _general_ci variant. People reading this now should probably use one of these newer collations instead of either _unicode_ci or _general_ci. The description of those older collations below is provided for interest only.

MySQL is currently transitioning away from an older, flawed UTF-8 implementation. For now, you need to use utf8mb4 instead of utf8 for the character encoding part, to ensure you are getting the fixed version. The flawed version remains for backward compatibility, though it is being deprecated.

Key differences

• utf8mb4_unicode_ci is based on the official Unicode rules for universal sorting and comparison, which sorts accurately in a wide range of languages.

• utf8mb4_general_ci is a simplified set of sorting rules which aims to do as well as it can while taking many short-cuts designed to improve speed. It does not follow the Unicode rules and will result in undesirable sorting or comparison in some situations, such as when using particular languages or characters.

  On modern servers, this performance boost will be all but negligible. It was devised in a time when servers had a tiny fraction of the CPU performance of today's computers.

Benefits of utf8mb4_unicode_ci over utf8mb4_general_ci

utf8mb4_unicode_ci, which uses the Unicode rules for sorting and comparison, employs a fairly complex algorithm for correct sorting in a wide range of languages and when using a wide range of special characters. These rules need to take into account language-specific conventions; not everybody sorts their characters in what we would call 'alphabetical order'.

As far as Latin (ie "European") languages go, there is not much difference between the Unicode sorting and the simplified utf8mb4_general_ci sorting in MySQL, but there are still a few differences:

• For examples, the Unicode collation sorts "ß" like "ss", and "Œ" like "OE" as people using those characters would normally want, whereas utf8mb4_general_ci sorts them as single characters (presumably like "s" and "e" respectively).

• Some Unicode characters are defined as ignorable, which means they shouldn't count toward the sort order and the comparison should move on to the next character instead. utf8mb4_unicode_ci handles these properly.

In non-latin languages, such as Asian languages or languages with different alphabets, there may be a lot more differences between Unicode sorting and the simplified utf8mb4_general_ci sorting. The suitability of utf8mb4_general_ci will depend heavily on the language used. For some languages, it'll be quite inadequate.

What should you use?

There is almost certainly no reason to use utf8mb4_general_ci anymore, as we have left behind the point where CPU speed is low enough that the performance difference would be important. Your database will almost certainly be limited by other bottlenecks than this.

In the past, some people recommended to use utf8mb4_general_ci except when accurate sorting was going to be important enough to justify the performance cost. Today, that performance cost has all but disappeared, and developers are treating internationalization more seriously.

There's an argument to be made that if speed is more important to you than accuracy, you may as well not do any sorting at all. It's trivial to make an algorithm faster if you do not need it to be accurate. So, utf8mb4_general_ci is a compromise that's probably not needed for speed reasons and probably also not suitable for accuracy reasons.

One other thing I'll add is that even if you know your application only supports the English language, it may still need to deal with people's names, which can often contain characters used in other languages in which it is just as important to sort correctly. Using the Unicode rules for everything helps add peace of mind that the very smart Unicode people have worked very hard to make sorting work properly.

What the parts mean

Firstly, ci is for case-insensitive sorting and comparison. This means it's suitable for textual data, and case is not important. The other types of collation are cs (case-sensitive) for textual data where case is important, and bin, for where the encoding needs to match, bit for bit, which is suitable for fields which are really encoded binary data (including, for example, Base64). Case-sensitive sorting leads to some weird results and case-sensitive comparison can result in duplicate values differing only in letter case, so case-sensitive collations are falling out of favor for textual data - if case is significant to you, then otherwise ignorable punctuation and so on is probably also significant, and a binary collation might be more appropriate.

Next, unicode or general refers to the specific sorting and comparison rules - in particular, the way text is normalized or compared. There are many different sets of rules for the utf8mb4 character encoding, with unicode and general being two that attempt to work well in all possible languages rather than one specific one. The differences between these two sets of rules are the subject of this answer. Note that unicode uses rules from Unicode 4.0. Recent versions of MySQL add the rulesets unicode_520 using rules from Unicode 5.2, and 0900 (dropping the "unicode_" part) using rules from Unicode 9.0.

And lastly, utf8mb4 is of course the character encoding used internally. In this answer I'm talking only about Unicode based encodings.

ASCII encoding is 7-bit, but in practice, characters encoded in ASCII are not stored in groups of 7 bits. Instead, one ASCII is stored in a byte, with the MSB usually set to 0 (yes, it's wasted in ASCII).

You can verify this by inputting a string in the ASCII character set in a text editor, setting the encoding to ASCII, and viewing the binary/hex:

Aside: the use of (strictly) ASCII encoding is now uncommon, in favor of UTF-8 (which does not waste the MSB mentioned above - in fact, an MSB of 1 indicates the code point is encoded with more than 1 byte).

        if marker in seen: continue
        seen[marker] = 1
        result.append(item)
    return result

ALTER TABLE can do multiple table alterations in one statement, but MODIFY COLUMN can only work on one column at a time, so you need to specify MODIFY COLUMN for each column you want to change:

ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100);

Also, note this warning from the manual:

When you use CHANGE or MODIFY, column_definition must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.

Use relative path with the pathlib module in Python 3.4+:

from pathlib import Path

Path(__file__).parent

You can use multiple calls to parent to go further in the path:

Path(__file__).parent.parent

As an alternative to specifying parent twice, you can use:

Path(__file__).parents[1]

Try to put android:gravity="center_vertical|right" inside parent LinearLayout else as you are inside RelativeLayout you can put android:layout_centerInParent="true" inside your scrollView.
