Anyone mentioned the script language used in Autohotkey ?
Worst language I ever used.

The example above from bchhun is nice except that you need to explicitly build your context dictionary from settings.py. Below is an UNTESTED example of how you could auto-build the context dictionary from all upper-case attributes of settings.py (re: "^[A-Z0-9_]+$").

At the end of settings.py:

_context = {} 
local_context = locals()
for (k,v) in local_context.items():
    if re.search('^[A-Z0-9_]+$',k):
        _context[k] = str(v)

def settings_context(context):
    return _context

TEMPLATE_CONTEXT_PROCESSORS = (
...
'myproject.settings.settings_context',
...
)

Using onclick instead will work. In theory it may not catch changes made via the keyboard but all browsers do seem to fire the event anyway when checking via keyboard.

You also need to pass the checkbox into the function:

function checkAddress(checkbox)
{
    if (checkbox.checked)
    {
        alert("a");
    }
}

HTML

<input type="checkbox" name="checkAddress" onclick="checkAddress(this)" />

I had this message when the type of a function parameter didn't fit. In my case it was a String instead of an URL.

You need to put all you .html files in the template folder next to your python module. And if there are any images that you are using in your html files then you need put all your files in the folder named static

In the following Structure

project/
    hello.py
    static/
        image.jpg
        style.css
    templates/
        homepage.html
    virtual/
        filename.json

% notation is called a format specifier. For example, %d tells printf() to print an integer. %s to print a string (char *) etc. You should really look it up here: http://google.com/search?q=printf+format+specifiers

No, commas are not used for string concatenation. Commas are for separating arguments passed to a function.

If you set the AllowsTransparency property on the Window (even without setting any transparency values) the border disappears and you can only resize via the grip.

<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Width="640" Height="480" 
    WindowStyle="None"
    AllowsTransparency="True"
    ResizeMode="CanResizeWithGrip">

    <!-- Content -->

</Window>

Result looks like:

I was experiencing the same issue.. I already had 4 controllers going and working just fine but when I added this one it returned "The requested resource does not support HTTP method 'GET'". I tried everything here and in a couple other relevant articles but was indifferent to the solution since, as Dan B. mentioned in response to the answer, I already had others working fine.

I walked away for a while, came back, and immediately realized that when I added the Controller it was nested under the "Controller" class and not "ApiController" class that my other Controllers were under. I'm assuming I chose the wrong scaffolding option to build the .cs file in Visual Studio. So I included the System.Web.Http namespace, changed the parent class, and everything works without the additional attributes or routing.

I was looking for a way to see if the element is going to come into view soon, so by extending the snippets above i managed to do it. thought i would leave this here just in case it will help someone

elm = is the element you want to check is in the view

scrollElement = you can pass window or a parent element that has a scroll

offset = if you want it to fire when the element is 200px away before its in the screen then pass 200

function isScrolledIntoView(elem, scrollElement, offset)_x000D_
        {_x000D_
            var $elem = $(elem);_x000D_
            var $window = $(scrollElement);_x000D_
            var docViewTop = $window.scrollTop();_x000D_
            var docViewBottom = docViewTop + $window.height();_x000D_
            var elemTop = $elem.offset().top;_x000D_
            var elemBottom = elemTop + $elem.height();_x000D_
            _x000D_
            return (((elemBottom+offset) >= docViewBottom) && ((elemTop-offset) <= docViewTop)) || (((elemBottom-offset) <= docViewBottom) && ((elemTop+offset) >= docViewTop));_x000D_
        }

var mask = /^\d+$/;
if ( myString.exec(mask) ){
   /* That's a number */
}

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

List<string> accountList = new List<string> {"123872", "987653" , "7625019", "028401"};

int i = accountList.FindIndex(x => x.StartsWith("762"));
//This will give you index of 7625019 in list that is 2. value of i will become 2.
//delegate(string ac)
//{
//    return ac.StartsWith(a.AccountNumber);
//}
//);

You can use Environment.Exit(0) and Application.Exit.

Environment.Exit(): terminates this process and gives the underlying operating system the specified exit code.

If you're doing this to several fields, or doing it quite often, then perhaps a plugin is the answer.
Here's the beginnings of a jQuery plugin that formats the value of a field to two decimal places.
It is triggered by the onchange event of the field. You may want something different.

<script type="text/javascript">

    // mini jQuery plugin that formats to two decimal places
    (function($) {
        $.fn.currencyFormat = function() {
            this.each( function( i ) {
                $(this).change( function( e ){
                    if( isNaN( parseFloat( this.value ) ) ) return;
                    this.value = parseFloat(this.value).toFixed(2);
                });
            });
            return this; //for chaining
        }
    })( jQuery );

    // apply the currencyFormat behaviour to elements with 'currency' as their class
    $( function() {
        $('.currency').currencyFormat();
    });

</script>   
<input type="text" name="one" class="currency"><br>
<input type="text" name="two" class="currency">

@aravk33 's answer is absolutely correct.

I was going through the same problem. I had a data set of 2450 images. I just could not figure out why I was facing this issue.

Check the dimensions of all the images in your training data.

Add the following snippet while appending your image into your list:

if image.shape==(1,512,512):
    trainx.append(image)

The simplest way is using libraries like google-http-java-client but if you want parse the JSON response by yourself you can do that in a multiple ways, you can use org.json, json-simple, Gson, minimal-json, jackson-mapper-asl (from 1.x)... etc

A set of simple examples:

Using Gson:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;

public class Gson {

    public static void main(String[] args) {
    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);
            String json = EntityUtils.toString(result.getEntity(), "UTF-8");

            com.google.gson.Gson gson = new com.google.gson.Gson();
            Response respuesta = gson.fromJson(json, Response.class);

            System.out.println(respuesta.getExample());
            System.out.println(respuesta.getFr());

        } catch (IOException ex) {
        }
        return null;
    }

    public class Response{

        private String example;
        private String fr;

        public String getExample() {
            return example;
        }
        public void setExample(String example) {
            this.example = example;
        }
        public String getFr() {
            return fr;
        }
        public void setFr(String fr) {
            this.fr = fr;
        }
    }
}

Using json-simple:

import java.io.IOException;

import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.util.EntityUtils;
import org.json.simple.JSONArray;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;

public class JsonSimple {

    public static void main(String[] args) {

    }

    public HttpResponse http(String url, String body) {

        try (CloseableHttpClient httpClient = HttpClientBuilder.create().build()) {
            HttpPost request = new HttpPost(url);
            StringEntity params = new StringEntity(body);
            request.addHeader("content-type", "application/json");
            request.setEntity(params);
            HttpResponse result = httpClient.execute(request);

            String json = EntityUtils.toString(result.getEntity(), "UTF-8");
            try {
                JSONParser parser = new JSONParser();
                Object resultObject = parser.parse(json);

                if (resultObject instanceof JSONArray) {
                    JSONArray array=(JSONArray)resultObject;
                    for (Object object : array) {
                        JSONObject obj =(JSONObject)object;
                        System.out.println(obj.get("example"));
                        System.out.println(obj.get("fr"));
                    }

                }else if (resultObject instanceof JSONObject) {
                    JSONObject obj =(JSONObject)resultObject;
                    System.out.println(obj.get("example"));
                    System.out.println(obj.get("fr"));
                }

            } catch (Exception e) {
                // TODO: handle exception
            }

        } catch (IOException ex) {
        }
        return null;
    }
}

etc...

For AWS if the user is ubuntu use the following to connect to remote server.

chmod 400 mykey.pem

ssh -i mykey.pem ubuntu@your-ip

You need to use ajax.

http://api.jquery.com/jQuery.ajax/

<code>
$.ajax({
  url: 'ajax/test.html',
  success: function(data) {
    $('.result').html(data);
    alert('Load was performed.');
  }
});
</code>

Try withColumn with the function when as follows:

val sqlContext = new SQLContext(sc)
import sqlContext.implicits._ // for `toDF` and $""
import org.apache.spark.sql.functions._ // for `when`

val df = sc.parallelize(Seq((4, "blah", 2), (2, "", 3), (56, "foo", 3), (100, null, 5)))
    .toDF("A", "B", "C")

val newDf = df.withColumn("D", when($"B".isNull or $"B" === "", 0).otherwise(1))

newDf.show() shows

+---+----+---+---+
|  A|   B|  C|  D|
+---+----+---+---+
|  4|blah|  2|  1|
|  2|    |  3|  0|
| 56| foo|  3|  1|
|100|null|  5|  0|
+---+----+---+---+

I added the (100, null, 5) row for testing the isNull case.

I tried this code with Spark 1.6.0 but as commented in the code of when, it works on the versions after 1.4.0.

That would be the %CD% variable.

@echo off
echo %CD%

%CD% returns the current directory the batch script is in.

UIApplication.shared.statusBarFrame.height was deprecated in iOS 13

'statusBarFrame' was deprecated in iOS 13.0: Use the statusBarManager property of the window scene instead.

You can retrieve status bar height in iOS 13 like follows:

let statusBarHeight = view.window?.windowScene?.statusBarManager?.statusBarFrame.height

NB! It's optional so make sure you have correct fallback.

If you print only "\r" to the console the cursor goes back to the beginning of the current line and then you can rewrite it. This should do the trick:

for(int i = 0; i < 100; ++i)
{
    Console.Write("\r{0}%   ", i);
}

Notice the few spaces after the number to make sure that whatever was there before is erased.
Also notice the use of Write() instead of WriteLine() since you don't want to add an "\n" at the end of the line.

On Linux you should be looking at using epoll for async I/O. It might also be worth fine-tuning socket-buffers to not waste too much kernel space per connection.

I would guess that you should be able to reach 100k connections on a reasonable machine.

This is improved @Vicky solution - it has clearInterval() added so it prevents a loop of reloading if the redirect takes too long:

                            $(document).ready(function () {
                                var myTimer = window.setInterval(function () {
                                    var timeLeft = $("#countdown").html();
                                    if (eval(timeLeft) == 0) {
                                        console.log('Now redirecting');
                                        clearInterval(myTimer);
                                        window.location = ("@Html.Raw(HttpUtility.HtmlDecode(redirectUrl))");
                                    } else {
                                        $("#countdown").html(eval(timeLeft) - eval(1));
                                    }
                                }, 1000);
                            });

Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:

var mvar = "";
$(".mbox").each(function() {
    console.log($(this).html());
    mvar += $(this).html();
});
console.log(mvar);

A good example is Git, which uses a strategy to store blobs. Why does it use hashes? Partly because these are easier to perform diffs on, but also because makes it simpler to optimise a COW strategy. When you make a new commit with few files changes the vast majority of objects and trees will not change. Therefore the commit, will through various pointers made of hashes reference a bunch of object that already exist, making the storage space required to store the entire history much smaller.

Vue watch() life-cycle hook, can be used

html

<div id="demo">{{ fullName }}</div>

js

var vm = new Vue({
  el: '#demo',
  data: {
    firstName: 'Foo',
    lastName: 'Bar',
    fullName: 'Foo Bar'
  },
  watch: {
    firstName: function (val) {
      this.fullName = val + ' ' + this.lastName
    },
    lastName: function (val) {
      this.fullName = this.firstName + ' ' + val
    }
  }
})

you should not use Nested List in List.

List<List<T>> 

is not legal, even if T were a defined type.

https://msdn.microsoft.com/en-us/library/ms182144.aspx

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

Record Count From Table One
---------------------------
            0

For basic formatting:

var template = jQuery.validator.format("{0} is not a valid value");
var result = template("abc");

Put the h1 and h2 in a container with an id of container then:

#container {
    display: flex;
    justify-content: space-beteen;
}

Take a look into NSColorWell class reference.

My problem was in add some library from tomcat to eclipse class path i just going to eclipse click right to project and going to debug configuration -> classpath -> Add External JARs add all jars files from apache-tomcat-7.0.35\bin this was my problem and it's worked for me .

Here are my working example

@RequestMapping(value = "/api/v1/files/upload", method =RequestMethod.POST)
public ResponseEntity<?> upload(@RequestParam("files") MultipartFile[] files) {
    LinkedMultiValueMap<String, Object> map = new LinkedMultiValueMap<>();
    List<String> tempFileNames = new ArrayList<>();
    String tempFileName;
    FileOutputStream fo;

    try {
        for (MultipartFile file : files) {
            tempFileName = "/tmp/" + file.getOriginalFilename();
            tempFileNames.add(tempFileName);
            fo = new FileOutputStream(tempFileName);
            fo.write(file.getBytes());
            fo.close();
            map.add("files", new FileSystemResource(tempFileName));
        }

        HttpHeaders headers = new HttpHeaders();
        headers.setContentType(MediaType.MULTIPART_FORM_DATA);

        HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity = new HttpEntity<>(map, headers);
        String response = restTemplate.postForObject(uploadFilesUrl, requestEntity, String.class);

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

    for (String fileName : tempFileNames) {
        File f = new File(fileName);
        f.delete();
    }
    return new ResponseEntity<Object>(HttpStatus.OK);
}

I always find it easier to learn a language in a specific problem domain. You might try looking at Django and doing the tutorial. This will give you a very light-weight intro to both Python and to a web framework (a very well-documented one) that is 100% Python.

Then do something in your field(s) of expertise -- graph generation, or whatever -- and tie that into a working framework to see if you got it right. My universe tends to be computational linguistics and there are a number of Python-based toolkits to help get you started. E.g. Natural Language Toolkit.

Just a thought.

As far as I remember, this is controlled by browser settings. In other words: user can chose whether they would like to open new tab in the background or foreground. Also they can chose whether new popup should open in new tab or just... popup.

For example in firefox preferences:

Notice the last option.

I have also encounter the same issue. One possible solution is to go to Xcode -> Preferences -> Accounts and from the left menu select on App ID then click on the View Details and tap on the refresh button. while reloading you will get following error

The selected team's agent, 'ADMIN NAME' must agree to the latest Program License Agreement.

If you will not get above error, Following solution will not work.

It means that you need to login into the developer account using Admin login and accept that latest agreement. Then you will be able to upload binary on the app store.

In the first two cases, you simply forgot to actually call the member function (!, it's not a value) std::vector<int>::size like this:

#include <vector>

int main () {
    std::vector<int> v;
    auto size = v.size();
}

Your third call

int size = v.size();

triggers a warning, as not every return value of that function (usually a 64 bit unsigned int) can be represented as a 32 bit signed int.

int size = static_cast<int>(v.size());

would always compile cleanly and also explicitly states that your conversion from std::vector::size_type to int was intended.

Note that if the size of the vector is greater than the biggest number an int can represent, size will contain an implementation defined (de facto garbage) value.

This topic is actually a little more complicated as described in the answers so far. This blogpost by Rob Norris explains it in more detail and gives examples on when using return will actually break your code (or at least have non-obvious effects).

At this point let me just quote the essence of the post. The most important statement is right in the beginning. Print this as a poster and put it to your wall :-)

The return keyword is not “optional” or “inferred”; it changes the meaning of your program, and you should never use it.

It gives one example, where it actually breaks something, when you inline a function

// Inline add and addR
def sum(ns: Int*): Int = ns.foldLeft(0)((n, m) => n + m) // inlined add

scala> sum(33, 42, 99)
res2: Int = 174 // alright

def sumR(ns: Int*): Int = ns.foldLeft(0)((n, m) => return n + m) // inlined addR

scala> sumR(33, 42, 99)
res3: Int = 33 // um.

because

A return expression, when evaluated, abandons the current computation and returns to the caller of the method in which return appears.

This is only one of the examples given in the linked post and it's the easiest to understand. There're more and I highly encourage you, to go there, read and understand.

When you come from imperative languages like Java, this might seem odd at first, but once you get used to this style it will make sense. Let me close with another quote:

If you find yourself in a situation where you think you want to return early, you need to re-think the way you have defined your computation.

Try this..

using System.Data.OleDb;

OleDbConnection dbConn;

dConn = new OleDbConnection("Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Registration.accdb;");

you can start the one when selecting one item from the left tree "virtual device" in AVD manager dialog on the platform of eclipse, the start UI has the option "Wipe User Data"

string str1, str2, str3;

cout << "These are the strings: " << endl;
cout << "str1: \"the dog jumped over the fence\"" << endl;
cout << "str2: \"the\"" << endl;
cout << "str3: \"that\"" << endl << endl;

From this, I see that you have not initialized str1, str2, or str3 to contain the values that you are printing. I might suggest doing so first:

string str1 = "the dog jumped over the fence", 
       str2 = "the",
       str3 = "that";

cout << "These are the strings: " << endl;
cout << "str1: \"" << str1 << "\"" << endl;
cout << "str2: \"" << str2 << "\"" << endl;
cout << "str3: \"" << str3 << "\"" << endl << endl;

Give this a shot...

public delegate bool TryParseDelegate<T>(string data, out T output);

public static T? ToNullablePrimitive<T>(this string data, 
    TryParseDelegate<T> func) where T:struct
{
    string.IsNullOrEmpty(data) return null;

    T output;

    if (func(data, out output))
    {
        return (T?)output;
    }

    return null;
}

Then call it like this...

void doStuff()
{
    string foo = "1.0";

    double? myDouble = foo.ToNullablePrimitive<double>(double.TryParse);

    foo = "1";

    int? myInt = foo.ToNullablePrimitive<int>(int.TryParse);

    foo = "haha";

    int? myInt2 = foo.ToNullablePrimitive<int>(int.TryParse);
}

Such problem might occur when you use surfire plugin 3.x.x+ with JUnit5 and by mistake annotate the test class with @Test annotation from JUnit4.

Use: org.junit.jupiter.api.Test (JUnit5) instead of org.junit.Test (Junit4)

NOTE: this might be hard to notice as the IDE might run this wihout problems just as JUnit4 test.

Hello sought a solution to make an Ajax form work with Google Tag Manager (GTM), the return false prevented the completion and submit the activation of the event in real time on google analytics solution was to change the return false by e.preventDefault (); that worked correctly follows the code:

 $("#Contact-Form").submit(function(e) {
    e.preventDefault();
   ...
});

If you use FluentNHibernate you can use following configuration code:

private ISessionFactory createSessionFactory()
{
    return Fluently.Configure()
            .Database(SQLiteConfiguration.Standard.UsingFileWithPassword(filename, password))
            .Mappings(m => m.FluentMappings.AddFromAssemblyOf<DBManager>())
            .ExposeConfiguration(this.buildSchema)
            .BuildSessionFactory();    
}

private void buildSchema(Configuration config)
{
        if (filename_not_exists == true)
        {
            new SchemaExport(config).Create(false, true);
        }
}    

Method UsingFileWithPassword(filename, password) encrypts a database file and sets password.
It runs only if the new database file is created. The old one not encrypted fails when is opened with this method.

Another alternative (other than binary operators suggested by @jm-) is to use ng-switch:

<span ng-switch on="interface">
   <img ng-switch-when="UP" src='green-checkmark.png'>
   <img ng-switch-default   src='big-black-X.png'>
</span>

ng-switch will likely be better/easier if you have more than two images.

Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...

So the solution was quite simple - I've just done this grant:

grant userB to userA;

That's all folks ;-)

Another requirement is that the object has to be owned by user userA before altering it...

No there actually is no way to prevent a user from doing a particular task. But you can always take measures! The image sharing websites have a huge team of developers working day and night to create such an algorithm where you prevent user from saving the image files.

First way

Try this:

$('img').mousedown(function (e) {
  if(e.button == 2) { // right click
    return false; // do nothing!
  }
}

So the user won't be able to click on the Save Image As... option from the menu and in turn he won't get a chance to save the image.

Second way

Other way is to use background-image. This way, the user won't be able to right click and Save the Image As... But he can still see the resources in the Inspector.

Third way

Even I am new to this one, few days ago I was surfing Flickr when I tried to right click, it did not let me do a thing. Which in turn was the first method that I provided you with. Then I tried to go and see the inspector, there I found nothing. Why? Since they were using background-image and at the same time they were using data:imagesource as its location.

Which was amazing for me too. You can precvent user from saving image files this way easily.

It is known as Data URI Scheme: http://en.wikipedia.org/wiki/Data_URI_scheme

Note

Please remember brother, when you're letting a user surf your website you're giving him READ permissions on the server side so he can read all the files without any problem. The same is the issue with image files. He can read the image files, and then he can easily save them. He downloads the images on the first place when he is surfing your website. So there is not an issue for him to save them on his disk.

Try this.........

ProgressDialog pd1;
pd1=new ProgressDialog(<current context reference here>);
pd1.setMessage("Loading....");
pd1.setCancelable(false);
pd1.show();

To dismiss....

if(pd1!=null)
 pd1.dismiss(); 

The Series class has a pandas.Series.dt accessor object with several useful datetime attributes, including dt.days. Access this attribute via:

timedelta_series.dt.days

You can also get the seconds and microseconds attributes in the same way.

Just put this in the first line of your script :

#!/usr/bin/env python

Make the file executable with

chmod +x myfile.py

Execute with

./myfile.py

Similar to @Aaron Digulla's suggestion except that I would suggest a graphics design tool, select the base color, in your case the background color, then adjust the Hue, Saturation and Value. Using this you can create color swatches very easily. Paint.Net is free and I use it all the time for this and also the pay-for-tools will also do this.

If you are using Firefox, alert(object.toSource()) should suffice for simple debugging purposes.

Yes, it is recommended to put the GA code in the footer anyway, as the page shouldnt count as a page visit until its read all the markup.

Is this what you need?

DataTable myDataTable = new DataTable();
List<int> myList = new List<int>();
foreach (DataRow row in myDataTable.Rows)
{
    myList.Add((int)row[0]);
}

This error:

python: can't open file 'test.py': [Errno 2] No such file or directory

Means that the file "test.py" doesn't exist. (Or, it does, but it isn't in the current working directory.)

I must save the file in any specific folder to make it run on terminal?

No, it can be where ever you want. However, if you just say, "test.py", you'll need to be in the directory containing test.py.

Your terminal (actually, the shell in the terminal) has a concept of "Current working directory", which is what directory (folder) it is currently "in".

Thus, if you type something like:

python test.py

test.py needs to be in the current working directory. In Linux, you can change the current working directory with cd. You might want a tutorial if you're new. (Note that the first hit on that search for me is this YouTube video. The author in the video is using a Mac, but both Mac and Linux use bash for a shell, so it should apply to you.)

set formatoptions-=t Keeps the visual textwidth but doesn't add new line in insert mode.

Brute force code to answer your question:

DataTable dt = new DataTable();

//for each of your properties
dt.Columns.Add("PropertyOne", typeof(string));

foreach(Entity entity in entities)
{
  DataRow row = dt.NewRow();

  //foreach of your properties
  row["PropertyOne"] = entity.PropertyOne;

  dt.Rows.Add(row);
}

DataSet ds = new DataSet();
ds.Tables.Add(dt);
return ds;

Now for the actual question. Why would you want to do this? As mentioned earlier, you can bind directly to an object list. Maybe a reporting tool that only takes datasets?

from Jackson 2.7.x+ there is a way to annotate the member variable itself:

 @JsonFormat(with = JsonFormat.Feature.ACCEPT_SINGLE_VALUE_AS_ARRAY)
 private List<String> newsletters;

More info here: Jackson @JsonFormat

    //import java.util.ArrayList;
    //import org.bson.Document;

    Document root = Document.parse("{\n"
            + "  \"name\": \"Json\",\n"
            + "  \"detail\": {\n"
            + "    \"first_name\": \"Json\",\n"
            + "    \"last_name\": \"Scott\",\n"
            + "    \"age\": \"23\"\n"
            + "  },\n"
            + "  \"status\": \"success\"\n"
            + "}");

    System.out.println(((String) root.get("name")));
    System.out.println(((String) ((Document) root.get("detail")).get("first_name")));
    System.out.println(((String) ((Document) root.get("detail")).get("last_name")));
    System.out.println(((String) ((Document) root.get("detail")).get("age")));
    System.out.println(((String) root.get("status")));

Problem With Android O API 26

If you stop the service right away (so your service does not actually really runs (wording / comprehension) and you are way under the ANR interval, you still need to call startForeground before stopSelf

https://plus.google.com/116630648530850689477/posts/L2rn4T6SAJ5

Tried this Approach But it Still creates an error:-

if (Util.SDK_INT > 26) {
    mContext.startForegroundService(playIntent);
} else {
    mContext.startService(playIntent);
}

I Am Using this until the Error is Resolved

mContext.startService(playIntent);

In a standard context, each connected user holds an explorer.exe process: The command [tasklist /V|find "explorer"] returns a line that contains the explorer.exe process owner's, with an adapted regex it is possible to obtain the required value. This also runs perfectly under Windows 7.

In rare cases explorer.exe is replaced by another program, the find filter can be adapted to match this case. If the command return an empty line then it is likely that no user is logged on. With Windows 7 it is also possible to run [query session|find ">"].

Your code may work without document.ready() just be sure that your script is after the #clicker. Checkout this demo: http://jsbin.com/aPAsaZo/1/

The idea in the ready concept. If you sure that your script is the latest thing in your page or it is after the affected element, it will work.

I guess ctype.h is the header file that you need to look at. it has numerous functions for handling digits as well as characters. isdigit or iswdigit is something that will help you in this case.

Here is a reference: http://docs.embarcadero.com/products/rad_studio/delphiAndcpp2009/HelpUpdate2/EN/html/devwin32/isdigit_xml.html

i think, this simple example should you explain the diffs between strong and dynamic typing:

>>> tup = ('1', 1, .1)
>>> for item in tup:
...     type(item)
...
<type 'str'>
<type 'int'>
<type 'float'>
>>>

java:

public static void main(String[] args) {
        int i = 1;
        i = "1"; //will be error
        i = '0.1'; // will be error
    }

The solution for eclipse photon seems to be:

1. open ./eclipse/configuration/org.eclipse.equinox.simpleconfigurator/bundles.info
2. delete the lines starting with org.eclipse.jpt (might work to only remove org.eclipse.jpt.jpa)

For anybody falling on this old solution. There is a better way from the mongoose docs.

var s = new Schema({ name: { type: String, unique: true }});
s.path('name').index({ unique: true });

As of current edited version of the post, you call setInterval at each change's end, adding a new "changer" with each new iterration. That means after first run, there's one of them ticking in memory, after 100 runs, 100 different changers change image 100 times every second, completely destroying performance and producing confusing results.

You only need to "prime" setInterval once. Remove it from function and place it inside onload instead of direct function call.

Recursion gets a bad rep, I'm always surprised by the number of developers that wont even touch recursion because someone told them it was evil incarnate.

I've learned through trial and error that when done properly recursion can be one of the fastest ways to iterate over something, it is not a steadfast rule and each language/ compiler/ engine has it's own quirks so mileage will vary.

In javascript I can reliably speed up almost any iterative process by introducing recursion with the added benefit of reducing side effects and making the code more clear concise and reusable. Also pro tip its possible to get around the stack overflow issue (and no you dont disable the warning).

My personal Pros & Cons:

Pros:

- Reduces side effects.
- Makes code more concise and easier to reason about.
- Reduces system resource usage and performs better than the traditional for loop.

Cons:

- Can lead to stack overflow.
- More complicated to setup than a traditional for loop.

Mileage will vary depending on language/ complier/ engine.

After reading through manny forums found a really easy solution.

I use redux-form. Urgo mapped redux-from fieldToClass. Upon error I navigate to the first error on the list of syncErrors.

No refs and no third party modules. Just simple querySelector & scrollIntoView

handleToScroll = (field) => {

    const fieldToClass = {
        'vehicleIdentifier': 'VehicleIdentifier',
        'locationTags': 'LocationTags',
        'photos': 'dropzoneContainer',
        'description': 'DescriptionInput',
        'clientId': 'clientId',
        'driverLanguage': 'driverLanguage',
        'deliveryName': 'deliveryName',
        'deliveryPhone': 'deliveryPhone',
        "deliveryEmail": 'deliveryEmail',
        "pickupAndReturn": "PickupAndReturn",
        "payInCash": "payInCash",
    }

document?.querySelector(`.${fieldToClasses[field]}`)
         .scrollIntoView({ behavior: "smooth" })

}

You can use length:

if($("#one").length) { // 0 == false; >0 == true
    alert('yes');
}

TL;DR

if (window.location.hash === "#_=_"){
    history.replaceState 
        ? history.replaceState(null, null, window.location.href.split("#")[0])
        : window.location.hash = "";
}

Full version with step by step instructions

// Test for the ugliness.
if (window.location.hash === "#_=_"){

    // Check if the browser supports history.replaceState.
    if (history.replaceState) {

        // Keep the exact URL up to the hash.
        var cleanHref = window.location.href.split("#")[0];

        // Replace the URL in the address bar without messing with the back button.
        history.replaceState(null, null, cleanHref);

    } else {

        // Well, you're on an old browser, we can get rid of the _=_ but not the #.
        window.location.hash = "";

    }

}

Step by step:

1. We'll only get into the code block if the fragment is #_=_.
2. Check if the browser supports the HTML5 window.replaceState method.
   1. Clean the URL by splitting on # and taking only the first part.
   2. Tell history to replace the current page state with the clean URL. This modifies the current history entry instead of creating a new one. What this means is the back and forward buttons will work just the way you want. ;-)
3. If the browser does not support the awesome HTML 5 history methods then just clean up the URL as best you can by setting the hash to empty string. This is a poor fallback because it still leaves a trailing hash (example.com/#) and also it adds a history entry, so the back button will take you back to #_-_.

Learn more about history.replaceState.

Learn more about window.location.

You can also use CASE - my code below checks for both null values and empty strings, and adds a seperator only if there is a value to follow:

SELECT OrganisationName, 
'Address' = 
CASE WHEN Addr1 IS NULL OR Addr1 = '' THEN '' ELSE Addr1 END + 
CASE WHEN Addr2 IS NULL OR Addr2 = '' THEN '' ELSE ', ' + Addr2 END + 
CASE WHEN Addr3 IS NULL OR Addr3 = '' THEN '' ELSE ', ' + Addr3 END + 
CASE WHEN County IS NULL OR County = '' THEN '' ELSE ', ' + County END 
FROM Organisations 

@ModelAttribute will create a attribute with the name specified by you (@ModelAttribute("Testing") Test test) as Testing in the given example ,Test being the bean test being the reference to the bean and Testing will be available in model so that you can further use it on jsp pages for retrieval of values that you stored in you ModelAttribute.

The AdamOptimizer class creates additional variables, called "slots", to hold values for the "m" and "v" accumulators.

See the source here if you're curious, it's actually quite readable: https://github.com/tensorflow/tensorflow/blob/master/tensorflow/python/training/adam.py#L39 . Other optimizers, such as Momentum and Adagrad use slots too.

These variables must be initialized before you can train a model.

The normal way to initialize variables is to call tf.initialize_all_variables() which adds ops to initialize the variables present in the graph when it is called.

(Aside: unlike its name suggests, initialize_all_variables() does not initialize anything, it only add ops that will initialize the variables when run.)

What you must do is call initialize_all_variables() after you have added the optimizer:

...build your model...
# Add the optimizer
train_op = tf.train.AdamOptimizer(1e-4).minimize(cross_entropy)
# Add the ops to initialize variables.  These will include 
# the optimizer slots added by AdamOptimizer().
init_op = tf.initialize_all_variables()

# launch the graph in a session
sess = tf.Session()
# Actually intialize the variables
sess.run(init_op)
# now train your model
for ...:
  sess.run(train_op)

Use include if you don't mind your script continuing without loading the file (in case it doesn't exist etc) and you can (although you shouldn't) live with a Warning error message being displayed.

Using require means your script will halt if it can't load the specified file, and throw a Fatal error.

Use LayoutBuilder and Get the output you want

Wrap the SingleChildScrollView with LayoutBuilder and implement the Builder function.

we can use a LayoutBuilder to get the box contains or the amount of space available.

LayoutBuilder(
    builder: (BuildContext context, BoxConstraints constraints){
      return SingleChildScrollView(
        child: Stack(
          children: <Widget>[
            Container(
              height: constraints.maxHeight,
            ),
            topTitle(context),
            middleView(context),
            bottomView(context),
          ],
        ),
      );
    }
)

My solution:

Object.prototype.__index = function(index)
{
    var i = -1;
    for (var key in this)
    {
        if (this.hasOwnProperty(key) && typeof(this[key])!=='function')
            ++i;
        if (i >= index)
            return this[key];
    }
    return null;
}
aObj = {'jack':3, 'peter':4, '5':'col', 'kk':function(){alert('hell');}, 'till':'ding'};
alert(aObj.__index(4));

I had the same problem but mine worked fine. Turn off your firewall, antivirus. Make sure your port 80 is enabled and both pcs are set to be remotely accessed. In each pc under users, add new user using the host ip address of the other pc. Restart all services. Put your wampserver online. It should connect

I'm currently experimenting with canvas and pixels... I'm finding this logic works out for me better.

1. Use this to calculate the grey-ness ( luma ? )
2. but with both the existing value and the new 'tint' value
3. calculate the difference ( I found I did not need to multiply )

4. add to offset the 'tint' value

   var grey =  (r + g + b) / 3;    
   var grey2 = (new_r + new_g + new_b) / 3;
   
   var dr =  grey - grey2 * 1;    
   var dg =  grey - grey2 * 1    
   var db =  grey - grey2 * 1;  
   
   tint_r = new_r + dr;    
   tint_g = new_g + dg;

You could use a Common Table Expression to create the SUM first, join it to the table, and then use the WHEN to to get the value from the CTE or the original table as necessary.

WITH PercentageOfTotal (Id, Percentage) 
AS 
(
    SELECT Id, (cnt / SUM(AreaId)) FROM dbo.MyTable GROUP BY Id
)
SELECT 
    CASE
        WHEN o.TotalType = 'Average' THEN r.avgscore
        WHEN o.TotalType = 'PercentOfTot' THEN pt.Percentage
        ELSE o.cnt
    END AS [displayscore]
FROM PercentageOfTotal pt
    JOIN dbo.MyTable t ON pt.Id = t.Id

Here is the reason. Starting from Jersey 2.26, Jersey removed HK2 as a hard dependency. It created an SPI as a facade for the dependency injection provider, in the form of the InjectionManager and InjectionManagerFactory. So for Jersey to run, we need to have an implementation of the InjectionManagerFactory. There are two implementations of this, which are for HK2 and CDI. The HK2 dependency is the jersey-hk2 others are talking about.

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.26</version>
</dependency>

The CDI dependency is

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-cdi2-se</artifactId>
    <version>2.26</version>
</dependency>

This (jersey-cdi2-se) should only be used for SE environments and not EE environments.

Jersey made this change to allow others to provide their own dependency injection framework. They don't have any plans to implement any other InjectionManagers, though others have made attempts at implementing one for Guice.

Although the question is solved, sharing knowledge for clarification of the correct meaning of the error.

The error says that the parameter needed to the concerned breaking function is not in the required format i.e. string or Buffer

The solution is to change the parameter to string

breakingFunction(JSON.stringify(offendingParameter), ... other params...);

or buffer

breakingFunction(BSON.serialize(offendingParameter), ... other params...);

In windows OS you see something like this:

C:\Users\yourusername\virtualEnvName\Scripts>activate
(virtualEnvName) C:\Users\yourusername\virtualEnvName\Scripts>

Parentheses mean that you are actually in the virtual environment called "virtualEnvName".

For me what happened was that I generated the app with rails new rails new chapter_2 but the RVM --default had rails 4.0.2 gem, but my chapter_2 project use a new gemset with rails 3.2.16.

So when I ran

rails generate scaffold User name:string email:string

the console showed

Usage:
   rails new APP_PATH [options]

So I fixed the RVM and the gemset with the rails 3.2.16 gem , and then generated the app again then I executed

 rails generate scaffold User name:string email:string

and it worked

Simple, just use .set_color

>>> barlist=plt.bar([1,2,3,4], [1,2,3,4])
>>> barlist[0].set_color('r')
>>> plt.show()

For your new question, not much harder either, just need to find the bar from your axis, an example:

>>> f=plt.figure()
>>> ax=f.add_subplot(1,1,1)
>>> ax.bar([1,2,3,4], [1,2,3,4])
<Container object of 4 artists>
>>> ax.get_children()
[<matplotlib.axis.XAxis object at 0x6529850>, 
 <matplotlib.axis.YAxis object at 0x78460d0>,  
 <matplotlib.patches.Rectangle object at 0x733cc50>, 
 <matplotlib.patches.Rectangle object at 0x733cdd0>, 
 <matplotlib.patches.Rectangle object at 0x777f290>, 
 <matplotlib.patches.Rectangle object at 0x777f710>, 
 <matplotlib.text.Text object at 0x7836450>, 
 <matplotlib.patches.Rectangle object at 0x7836390>, 
 <matplotlib.spines.Spine object at 0x6529950>, 
 <matplotlib.spines.Spine object at 0x69aef50>,
 <matplotlib.spines.Spine object at 0x69ae310>, 
 <matplotlib.spines.Spine object at 0x69aea50>]
>>> ax.get_children()[2].set_color('r') 
 #You can also try to locate the first patches.Rectangle object 
 #instead of direct calling the index.

If you have a complex plot and want to identify the bars first, add those:

>>> import matplotlib
>>> childrenLS=ax.get_children()
>>> barlist=filter(lambda x: isinstance(x, matplotlib.patches.Rectangle), childrenLS)
[<matplotlib.patches.Rectangle object at 0x3103650>, 
 <matplotlib.patches.Rectangle object at 0x3103810>, 
 <matplotlib.patches.Rectangle object at 0x3129850>, 
 <matplotlib.patches.Rectangle object at 0x3129cd0>, 
 <matplotlib.patches.Rectangle object at 0x3112ad0>]

As already answered here (and here and here), mergetool is the command to configure this. For a nice graphical frontend I recommend kdiff3 (GPL).

You need to use the property /a on the set command.

For example,

set /a "c=%a%+%b%"

This allows you to use arithmetic expressions in the set command, rather than simple concatenation.

Your code would then be:

@set a=3
@set b=4
@set /a "c=%a%+%b%"
echo %c%
@set /a "d=%c%+1"
echo %d%

and would output:

7
8

You can get the user name using System.Security.Principal.WindowsIdentity.GetCurrent() but there is not way to get current user password!

Just with the above answer I hope it was the problem.

$_POST['search'] instead of $_post['search']

And again use LIKE '%$name%' instead of LIKE '%{$name}%'

As we know jQuery validate plugin invalidates Select field when it has blank value. Why don't we set its value to blank when required.

Yes, you can validate select field with some predefined value.

$("#everything").validate({
    rules: {
        select_field:{
            required: {
                depends: function(element){
                    if('none' == $('#select_field').val()){
                        //Set predefined value to blank.
                        $('#select_field').val('');
                    }
                    return true;
                }
            }
        }
    }
});

We can set blank value for select field but in some case we can't. For Ex: using a function that generates Dropdown field for you and you don't have control over it.

I hope it helps as it helps me.

Try wrapping the spans in an anchor tag and apply the background image to that.

HTML:

<div class="header">
    <a href="/">
        <span class="header-title">My gray sea design</span><br />
        <span class="header-title-two">A beautiful design</span>
    </a>
</div>

CSS:

.header {
    border-bottom:1px solid #eaeaea;
}

.header a {
    display: block;
    background-image: url("./images/embouchure.jpg");
    background-repeat: no-repeat;
    height:160px;
    padding-left:280px;
    padding-top:50px;
    width:470px;
    color: #eaeaea;
}

What he said. You can handle the exceptions however you like, but Thread.sleep(miliseconds); is the best route to take.

public static void main(String[] args) throws InterruptedException {

Random random = new Random();

double NextDouble(double minimum, double maximum)
{  

    return random.NextDouble()*random.Next(minimum,maximum);

}

In order to add a label to the map you need to create a custom overlay. The sample at http://blog.mridey.com/2009/09/label-overlay-example-for-google-maps.html uses a custom class, Layer, that inherits from OverlayView (which inherits from MVCObject) from the Google Maps API. He has a revised version (adds support for visibility, zIndex and a click event) which can be found here: http://blog.mridey.com/2011/05/label-overlay-example-for-google-maps.html

The following code is taken directly from Marc Ridey's Blog (the revised link above).

Layer class

// Define the overlay, derived from google.maps.OverlayView
function Label(opt_options) {
  // Initialization
  this.setValues(opt_options);


  // Label specific
  var span = this.span_ = document.createElement('span');
  span.style.cssText = 'position: relative; left: -50%; top: -8px; ' +
  'white-space: nowrap; border: 1px solid blue; ' +
  'padding: 2px; background-color: white';


  var div = this.div_ = document.createElement('div');
  div.appendChild(span);
  div.style.cssText = 'position: absolute; display: none';
};
Label.prototype = new google.maps.OverlayView;


// Implement onAdd
Label.prototype.onAdd = function() {
  var pane = this.getPanes().overlayImage;
  pane.appendChild(this.div_);


  // Ensures the label is redrawn if the text or position is changed.
  var me = this;
  this.listeners_ = [
    google.maps.event.addListener(this, 'position_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'visible_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'clickable_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'text_changed', function() { me.draw(); }),
    google.maps.event.addListener(this, 'zindex_changed', function() { me.draw(); }),
    google.maps.event.addDomListener(this.div_, 'click', function() {
      if (me.get('clickable')) {
        google.maps.event.trigger(me, 'click');
      }
    })
  ];
};

// Implement onRemove
Label.prototype.onRemove = function() {
 this.div_.parentNode.removeChild(this.div_);

 // Label is removed from the map, stop updating its position/text.
 for (var i = 0, I = this.listeners_.length; i < I; ++i) {
   google.maps.event.removeListener(this.listeners_[i]);
 }
};

// Implement draw
Label.prototype.draw = function() {
 var projection = this.getProjection();
 var position = projection.fromLatLngToDivPixel(this.get('position'));

 var div = this.div_;
 div.style.left = position.x + 'px';
 div.style.top = position.y + 'px';
 div.style.display = 'block';

 this.span_.innerHTML = this.get('text').toString();
};

Note: this answer is for Express 2. See here for Express 3.

If you're using connect/express, you should use the bodyParser middleware: It's described in the Expressjs guide.

// example using express.js:
var express = require('express')
  , app = express.createServer();
app.use(express.bodyParser());
app.post('/', function(req, res){
  var email = req.param('email', null);  // second parameter is default
});

Here's the original connect-only version:

// example using just connect
var connect = require('connect');
var url = require('url');
var qs = require('qs');
var server = connect(
  connect.bodyParser(),
  connect.router(function(app) {
    app.post('/userlogin', function(req, res) {
      // the bodyParser puts the parsed request in req.body.
      var parsedUrl = qs.parse(url.parse(req.url).query);
      var email = parsedUrl.email || req.body.email;;
    });
  })
);

Both the querystring and body are parsed using Rails-style parameter handling (qs) rather than the low-level querystring library. In order to parse repeated parameters with qs, the parameter needs to have brackets: name[]=val1&name[]=val2. It also supports nested maps. In addition to parsing HTML form submissions, the bodyParser can parse JSON requests automatically.

Edit: I read up on express.js and modified my answer to be more natural to users of Express.

sizeof(buffer) is the size of a pointer on your last line NOT the actual size of the buffer. You need to use "length" that you already established instead

My project of spring-boot has run normally according to your assistance. The yaml datasource configuration is:

spring:
  # (DataSourceAutoConfiguration & DataSourceProperties)
  datasource:
    name: ds-h2
    url: jdbc:h2:D:/work/workspace/fdata;DATABASE_TO_UPPER=false
    username: h2
    password: h2
    driver-class: org.h2.Driver

Custom DataSource

@Configuration
@Component
public class DataSourceBean {

    @ConfigurationProperties(prefix = "spring.datasource")
    @Bean
    @Primary
    public DataSource getDataSource() {
        return DataSourceBuilder
                .create()
//                .url("jdbc:h2:D:/work/workspace/fork/gs-serving-web-content/initial/data/fdata;DATABASE_TO_UPPER=false")
//                .username("h2")
//                .password("h2")
//                .driverClassName("org.h2.Driver")
                .build();
    }
}

Let's say you have a path with a file in this format:

/dirA/dirB/dirC/filename.file

Now you only want the path which includes four "/". Type

$ echo "/dirA/dirB/dirC/filename.file" | cut -f1-4 -d"/"

and your output will be

/dirA/dirB/dirC

The advantage of using cut is that you can also cut out the uppest directory as well as the file (in this example), so if you type

$ echo "/dirA/dirB/dirC/filename.file" | cut -f1-3 -d"/"

your output would be

/dirA/dirB

Though you can do the same from the other side of the string, it would not make that much sense in this case as typing

$ echo "/dirA/dirB/dirC/filename.file" | cut -f2-4 -d"/"

results in

dirA/dirB/dirC

In some other cases the last case might also be helpful. Mind that there is no "/" at the beginning of the last output.

Here's some meta-knowledge for you - if you want to know what you can do with an Array, check the documentation - here's the Array page for Mozilla

https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Array

There you'll see reference to indexOf, added in Javascript 1.6

No magic involved, just subtract from the offset top of the element

$('html, body').animate({scrollTop: $('#contact').offset().top -100 }, 'slow');

If you are using curl versions curl-7.19.7-46.el6.x86_64 or older. Please provide an option as -k1 (small K1).

The instance in which you're using a single character (i.e. | or &) is a bitwise comparison of the results. As long as your language evaluates these expressions to a binary value they should return the same results. As a best practice, however, you should use the logical operator as that's what you mean (I think).

Use FileUtils from Apache commons.

listFiles

public static Collection<File> listFiles(File directory,
                                         String[] extensions,
                                         boolean recursive)
Finds files within a given directory (and optionally its subdirectories) which match an array of extensions.
Parameters:
directory - the directory to search in
extensions - an array of extensions, ex. {"java","xml"}. If this parameter is null, all files are returned.
recursive - if true all subdirectories are searched as well
Returns:
an collection of java.io.File with the matching files

Annotations come from the support's library which are packaged in android.support.annotation.

As another option you can use @NonNull annotation which denotes that a parameter, field or method return value can never be null.
It is imported from import android.support.annotation.NonNull;

Basically one needs to create a custom background for a spinner. It should be something like this:

spinner_background.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item>

        <layer-list>

            <item>
                <color
                    android:color="@android:color/white"/>
            </item>

            <item>
                <bitmap
                    android:gravity="center_vertical|right"
                    android:src="@drawable/ic_arrow_drop_down_black_24dp"/>
            </item>

        </layer-list>

    </item>

</selector>

Then create a custom style for your spinner, where you specify the above selector as background:

<style name="Widget.App.Spinner" parent="@style/Widget.AppCompat.Spinner">
    <item name="overlapAnchor">true</item>
    <item name="android:background">@drawable/spinner_background</item>
</style>

And finally in your app theme you should override two attributes if you want it to be applied all across your app:

<item name="spinnerStyle">@style/Widget.App.Spinner</item>
<item name="android:spinnerStyle">@style/Widget.App.Spinner</item>

And that's pretty much it.

Are you explicitly setting the values as blank? For example:

<input type="text" name="textfield" value="">

That should stop browsers putting data in where it shouldn't. Alternatively, you can add the autocomplete attribute to the form tag:

<form autocomplete="off" ...></form>

Building on the answer by @JoelCoehoorn, my approach is to leave all my PRINT statements in place, and simply follow them with the RAISERROR statement to cause the flush.

For example:

PRINT 'MyVariableName: ' + @MyVariableName
RAISERROR(N'', 0, 1) WITH NOWAIT

The advantage of this approach is that the PRINT statements can concatenate strings, whereas the RAISERROR cannot. (So either way you have the same number of lines of code, as you'd have to declare and set a variable to use in RAISERROR).

If, like me, you use AutoHotKey or SSMSBoost or an equivalent tool, you can easily set up a shortcut such as "]flush" to enter the RAISERROR line for you. This saves you time if it is the same line of code every time, i.e. does not need to be customised to hold specific text or a variable.

I needed something like this for a game's control configuration UI, so I compiled a list for the standard US keyboard layout keycodes and mapped them to their respective key names.

Here's a fiddle that contains a map for code -> name and visi versa: http://jsfiddle.net/vWx8V/

If you want to support other key layouts you'll need to modify these maps to accommodate for them separately.

That is unless you were looking for a list of keycode values that included the control characters and other special values that are not (or are rarely) possible to input using a keyboard and may be outside of the scope of the keydown/keypress/keyup events of Javascript. Many of them are control characters or special characters like null (\0) and you most likely won't need them.

Notice that the number of keys on a full keyboard is less than many of the keycode values.

1. Check the latest Jest (v 0.22): https://github.com/facebook/jest

2. The Facebook team adds the Istanbul code coverage output as part of the coverage report and you can use it directly.

3. After executing Jest, you can get a coverage report in the console and under the root folder set by Jest, you will find the coverage report in JSON and HTML format.

4. FYI, if you install from npm, you might not get the latest version; so try the GitHub first and make sure the coverage is what you need.

Actually you can ;) It's just a matter of user experience, right?

Try this, (1) for list control set

listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);   
listView.setItemsCanFocus(false);

(2) define list item as

<CheckedTextView 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:gravity="center_vertical"
    android:paddingLeft="6dip"
    android:paddingRight="6dip"
    android:checkMark="?android:attr/listChoiceIndicatorMultiple"
    android:background="@drawable/txt_view_bg" />

This is same as android.R.layout.simple_list_item_multiple_choice except android:background="@drawable/txt_view_bg

(3) And define drawable txt_view_bg.xml as

<item android:drawable="@drawable/selected"
  android:state_checked="true" />  
<item android:drawable="@drawable/not_selected" />

Note:- The preferred way to handle multiple choice is to track choices your-self with on click item click, rather than depending on its state in list.

@Context ServletContext ctx;

    response.setHeader("Content-Length", String.valueOf(file.length()));
    response.setHeader("Content-Disposition", "attachment; filename=\""+ file.getName() + "\"");
    return new StreamingOutput() {
        @Override
        public void write(OutputStream output) throws IOException,
                WebApplicationException {
            Utils.writeBuffer(new BufferedInputStream(new FileInputStream(file)), new BufferedOutputStream(output));
        }
    };
}

You need to add the following lines in your catalina.sh file.

export CATALINA_OPTS="-Xms512M -Xmx1024M"

UPDATE : catalina.sh content clearly says -

Do not set the variables in this script. Instead put them into a script setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

So you can add above in setenv.sh instead (create a file if it does not exist).

Synchronous functions are blocking while asynchronous functions are not. In synchronous functions, statements complete before the next statement is run. In this case, the program is evaluated exactly in order of the statements and execution of the program is paused if one of the statements take a very long time.

Asynchronous functions usually accept a callback as a parameter and execution continue on the next line immediately after the asynchronous function is invoked. The callback is only invoked when the asynchronous operation is complete and the call stack is empty. Heavy duty operations such as loading data from a web server or querying a database should be done asynchronously so that the main thread can continue executing other operations instead of blocking until that long operation to complete (in the case of browsers, the UI will freeze).

For version 4.x you can now use the req.baseUrl in addition to req.path to get the full path. For example, the OP would now do something like:

//auth required or redirect
app.use('/account', function(req, res, next) {
  console.log(req.baseUrl + req.path);  // => /account

  if(!req.session.user) {
    res.redirect('/login?ref=' + encodeURIComponent(req.baseUrl + req.path));  // => /login?ref=%2Faccount
  } else {
    next();
  }
});

I had similar problem before. But this was resolved when I started using hostname instead of IP address in my connection string.

You need to set a constraint on the table to trigger a "conflict" which you then resolve by doing a replace:

CREATE TABLE data   (id INTEGER PRIMARY KEY, event_id INTEGER, track_id INTEGER, value REAL);
CREATE UNIQUE INDEX data_idx ON data(event_id, track_id);

Then you can issue:

INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 2, 2, 3);
INSERT OR REPLACE INTO data VALUES (NULL, 1, 2, 5);

The "SELECT * FROM data" will give you:

Note that the data.id is "3" and not "1" because REPLACE does a DELETE and INSERT, not an UPDATE. This also means that you must ensure that you define all necessary columns or you will get unexpected NULL values.

If its just a natty little app with one or two ListViews I normally just create a little helper property:

private ListViewItem SelectedItem { get { return (listView1.SelectedItems.Count > 0 ? listView1.SelectedItems[0] : null); } }

If I have loads, then move it out to a helper class:

internal static class ListViewEx
{
    internal static ListViewItem GetSelectedItem(this ListView listView1)
    {
        return (listView1.SelectedItems.Count > 0 ? listView1.SelectedItems[0] : null);
    }
}

so:

ListViewItem item = lstFixtures.GetSelectedItem();

The ListView interface is a bit rubbish so I normally find the helper class grows quite quickly.

Assuming Nothing Follows Them

If these two div elements are basically your main layout elements, and nothing follows them in the html, then there is a pure HMTL/CSS solution that takes the normal order shown in this fiddle and is able to flip it vertically as shown in this fiddle using one additional wrapper div like so:

HTML

<div class="wrapper flipit">
   <div id="first_div">first div</div>
   <div id="second_div">second div</div>
</div>

CSS

.flipit {
    position: relative;
}
.flipit #first_div {
    position: absolute;
    top: 100%;
    width: 100%;
}

This would not work if elements follow these div's, as this fiddle illustrates the issue if the following elements are not wrapped (they get overlapped by #first_div), and this fiddle illustrates the issue if the following elements are also wrapped (the #first_div changes position with both the #second_div and the following elements). So that is why, depending on your use case, this method may or may not work.

For an overall layout scheme, where all other elements exist inside the two div's, it can work. For other scenarios, it will not.

Just include windows.h instead of stdfax or create a clean project without template.

I found simple solution which worked for me.

Make your fragment adapter extends FragmentStatePagerAdapter instead of FragmentPagerAdapter and override method onSave to return null

@Override
public Parcelable saveState()
{
    return null;
}

This prevent android from recreating fragment

One day later I found another and better solution.

Call setRetainInstance(true) for all your fragments and save references to them somewhere. I did that in static variable in my activity, because it's declared as singleTask and fragments can stay the same all the time.

This way android not recreate fragments but use same instances.

I'd like to understand how the respond_to block actually works. What type of variable is format? Are .html and .json methods of the format object?

In order to understand what format is, you could first look at the source for respond_to, but quickly you'll find that what really you need to look at is the code for retrieve_response_from_mimes.

From here, you'll see that the block that was passed to respond_to (in your code), is actually called and passed with an instance of Collector (which within the block is referenced as format). Collector basically generates methods (I believe at Rails start-up) based on what mime types rails knows about.

So, yes, the .html and .json are methods defined (at runtime) on the Collector (aka format) class.

The only thing you can do is to upload the image to a server and check the image size and dimension using some server side language like C#.

Edit:

Your need can't be done using javascript only.

For the particular case of Windows 10 October 2018 Update or later activedirectory module is not available unless the optional feature RSAT: Active Directory Domain Services and Lightweight Directory Services Tools is installed (instructions here + uncollapse install instructions).

Reopen Windows Powershell and import-module activedirectory will work as expected.

MySQL function example:

Open the mysql terminal:

el@apollo:~$ mysql -u root -pthepassword yourdb
mysql>

Drop the function if it already exists

mysql> drop function if exists myfunc;
Query OK, 0 rows affected, 1 warning (0.00 sec)

Create the function

mysql> create function hello(id INT)
    -> returns CHAR(50)
    -> return 'foobar';
Query OK, 0 rows affected (0.01 sec)

Create a simple table to test it out with

mysql> create table yar (id INT);
Query OK, 0 rows affected (0.07 sec)

Insert three values into the table yar

mysql> insert into yar values(5), (7), (9);
Query OK, 3 rows affected (0.04 sec)
Records: 3  Duplicates: 0  Warnings: 0

Select all the values from yar, run our function hello each time:

mysql> select id, hello(5) from yar;
+------+----------+
| id   | hello(5) |
+------+----------+
|    5 | foobar   |
|    7 | foobar   |
|    9 | foobar   |
+------+----------+
3 rows in set (0.01 sec)

Verbalize and internalize what just happened:

You created a function called hello which takes one parameter. The parameter is ignored and returns a CHAR(50) containing the value 'foobar'. You created a table called yar and added three rows to it. The select statement runs the function hello(5) for each row returned by yar.

You can use

my_array=( $(<command>) )

to store the output of command <command> into the array my_array.

You can access the length of that array using

my_array_length=${#my_array[@]}

Now the length is stored in my_array_length.

Coupling has to do with dependencies between systems, which could be modules of code (functions, files, or classes), tools in a pipeline, server-client processes, and so forth. The less general the dependencies are, the more "tightly coupled" they become, since changing one system required changing the other systems that rely on it. The ideal situation is "loose coupling" where one system can be changed and the systems depending on it will continue to work without modification.

The general way to achieve loose coupling is through well defined interfaces. If the interaction between two systems is well defined and adhered to on both sides, then it becomes easier to modify one system while ensuring that the conventions are not broken. It commonly occurs in practice that no well-defined interface is established, resulting in a sloppy design and tight coupling.

Some examples:

• Application depends on a library. Under tight coupling, app breaks on newer versions of the lib. Google for "DLL Hell".

• Client app reads data from a server. Under tight coupling, changes to the server require fixes on the client side.

• Two classes interact in an Object-Oriented hierarchy. Under tight coupling, changes to one class require the other class to be updated to match.

• Multiple command-line tools communicate in a pipe. If they are tightly coupled, changes to the version of one command-line tool will cause errors in the tools that read its output.

Just use a MaterialButton and the app:backgroundTint and android:textColor attributes:

<MaterialButton
  app:backgroundTint="@color/my_color"
  android:textColor="@android:color/white"/>

All of these answers should suffice. However if you don't have a defined width, auto margins will not work.

I have found this nifty little trick to centre some of the more stubborn elements (Particularly images).

.div {
   position: absolute;
   left: 0;
   right: 0;
   margin-left: 0;
   margin-right: 0;
}

There was a Python enhancement proposal PEP 299 which aimed to replace if __name__ == '__main__': idiom with def __main__:, but it was rejected. It's still a good read to know what to keep in mind when using if __name__ = '__main__':.

Try this

$("[id*='type']").click(
function () {
var isCheckboxChecked = this.checked;
$("[id*='type']").attr('checked', false);
this.checked = isCheckboxChecked;
});

To make it even more generic you can also find checkboxes by the common class implemented on them.

Modified...

Here is the best, simple, short and clean way to "rename" the text of an input with file type and without JQuery, with pure HTML and javascript:

<input id='browse' type='file' style='width:0px'>
<button id='browser' onclick='browse.click()'>
    *The text you want*
</button>

If you're iterating over an object instead of an array, you'll need to access the properties using:

$id = $blog->id;
$title = $blog->title;
$content = $blog->content;

That, or change your object to an array.

Try this code :

return context.EntitytableName.AsEnumerable().Find(p => p.LoginID.Equals(loginID) && p.Password.Equals(password)).Select(p => new ModelTableName{ FirstName = p.FirstName, UserID = p.UserID });

private static String toUnicode(char ch) {
    return String.format("\\u%04x", (int) ch);
}

I had exactly the same problem with my VS 2013 solutions when I install VS 2017 and Crystal Reports SP21. In fact it's because VS does not necessarily convert the solution in the first launch.

Once you have installed Crystal Report SP 21, make sure that VS 2017 upgrade your solution : a window must appear "SAP Crystal Reports, version for Visual" with a radio button "Convert the solution".

Screenshot in french :

When I used the menu "File / Open / Project/Solution", the conversion was not done.

I have to do that :

1. Add VS 2017 on the tasks bar
2. Run VS 2017 and Open the solution with File menu
3. Try to build the project, errors appear with Crystal Reports
4. Close VS 2017
5. Right click on VS 2017 shortcur in then tasks bar and open the solution directly
6. The conversion run this time, you can open .rpt and the solution build without error.

I came up with this. Maybe you can improve it. Especially the method of generating the quantiles of the distribution seems cumbersome to me.

You could replace np.random.normal with any other distribution from np.random to compare data against other distributions.

#!/bin/python

import numpy as np

measurements = np.random.normal(loc = 20, scale = 5, size=100000)

def qq_plot(data, sample_size):
    qq = np.ones([sample_size, 2])
    np.random.shuffle(data)
    qq[:, 0] = np.sort(data[0:sample_size])
    qq[:, 1] = np.sort(np.random.normal(size = sample_size))
    return qq

print qq_plot(measurements, 1000)

Define a class like this :

public class myclass {
       string id ;
       string title ;
       string content;
 }

 public class program {
        public void Main () {
               List<myclass> objlist = new List<myclass> () ;
               foreach (var value in objlist)  {
                       TextBox1.Text = value.id ;
                       TextBox2.Text= value.title;
                       TextBox3.Text= value.content ;
                }
         }
  }

I tried to draw a sketch and you can improve it in many ways. Instead of defining class "myclass", you can define struct.

A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer. There are three different ways where Pointer acts as dangling pointer.

1. De-allocation of memory
2. Function Call
3. Variable goes out of scope

You need to use HTML on a web page to get line breaks. For example "<br/>" will give you a line break.

Ronal, to answer your question in the comment in my answer above:

function wasClicked(str)
{
  return str+' def';
}

I found this method: Matcher.replaceAll(String replacement); In java.util.regex.Matcher.java you can see more:

 /**
 * Replaces every subsequence of the input sequence that matches the
 * pattern with the given replacement string.
 *
 * <p> This method first resets this matcher.  It then scans the input
 * sequence looking for matches of the pattern.  Characters that are not
 * part of any match are appended directly to the result string; each match
 * is replaced in the result by the replacement string.  The replacement
 * string may contain references to captured subsequences as in the {@link
 * #appendReplacement appendReplacement} method.
 *
 * <p> Note that backslashes (<tt>\</tt>) and dollar signs (<tt>$</tt>) in
 * the replacement string may cause the results to be different than if it
 * were being treated as a literal replacement string. Dollar signs may be
 * treated as references to captured subsequences as described above, and
 * backslashes are used to escape literal characters in the replacement
 * string.
 *
 * <p> Given the regular expression <tt>a*b</tt>, the input
 * <tt>"aabfooaabfooabfoob"</tt>, and the replacement string
 * <tt>"-"</tt>, an invocation of this method on a matcher for that
 * expression would yield the string <tt>"-foo-foo-foo-"</tt>.
 *
 * <p> Invoking this method changes this matcher's state.  If the matcher
 * is to be used in further matching operations then it should first be
 * reset.  </p>
 *
 * @param  replacement
 *         The replacement string
 *
 * @return  The string constructed by replacing each matching subsequence
 *          by the replacement string, substituting captured subsequences
 *          as needed
 */
public String replaceAll(String replacement) {
    reset();
    StringBuffer buffer = new StringBuffer(input.length());
    while (find()) {
        appendReplacement(buffer, replacement);
    }
    return appendTail(buffer).toString();
}

Simple solution to resolve this problem is to set an empty value by default :

<input name='myInput' value={this.state.myInput || ''} onChange={this.handleChange} />

I was successful using tidy command line utility. On linux I installed it quickly with apt-get install tidy. Then the command:

tidy -q -asxml --numeric-entities yes source.html >file.xml

gave an xml file, which I was able to process with xslt processor. However I needed to set up xhtml1 dtds correctly.

This is their homepage: html-tidy.org (and the legacy one: HTML Tidy)

I found the example RichardTheKiwi quite informative.

Just to offer another approach if you're looking for something like IF EXISTS (SELECT 1 ..) THEN ...

-- what I might write in MSSQL

IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='')
BEGIN
    SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
    INSERT INTO TABLE(FieldValue) VALUES('')
    SELECT SCOPE_IDENTITY() AS TableID
END

-- rewritten for MySQL

IF (SELECT 1 = 1 FROM Table WHERE FieldValue='') THEN
BEGIN
    SELECT TableID FROM Table WHERE FieldValue='';
END;
ELSE
BEGIN
    INSERT INTO Table (FieldValue) VALUES('');
    SELECT LAST_INSERT_ID() AS TableID;
END;
END IF;

In addition to editing .bowerrc to setup your default install path, you can also setup custom install paths for different file types.

There is a node package called bower-installer that provides a single command for managing alternate install paths.

run npm install -g bower-installer

Set up your bower.json

{
  "name" : "test",
  "version": "0.1",
  "dependencies" : {
    "jquery-ui" : "latest"
  },
  "install" : {
    "path" : {
      "css": "src/css",
      "js": "src/js"
    },
    "sources" : {
      "jquery-ui" : [
        "components/jquery-ui/ui/jquery-ui.custom.js",
        "components/jquery-ui/themes/start/jquery-ui.css"
      ]
    }
  }
}

Run the following command: bower-installer

This will install components/jquery-ui/themes/start/jquery-ui.css to ./src/css, etc

For whatever reason, @AliUmair reverted the edit to his answer that fixes his code that doesn't run as is, so here is the working version that doesn't have the file access error and properly handles null object property values:

/// <summary>
/// Creates the CSV from a generic list.
/// </summary>;
/// <typeparam name="T"></typeparam>;
/// <param name="list">The list.</param>;
/// <param name="csvNameWithExt">Name of CSV (w/ path) w/ file ext.</param>;
public static void CreateCSVFromGenericList<T>(List<T> list, string csvCompletePath)
{
    if (list == null || list.Count == 0) return;

    //get type from 0th member
    Type t = list[0].GetType();
    string newLine = Environment.NewLine;

    if (!Directory.Exists(Path.GetDirectoryName(csvCompletePath))) Directory.CreateDirectory(Path.GetDirectoryName(csvCompletePath));

    using (var sw = new StreamWriter(csvCompletePath))
    {
        //make a new instance of the class name we figured out to get its props
        object o = Activator.CreateInstance(t);
        //gets all properties
        PropertyInfo[] props = o.GetType().GetProperties();

        //foreach of the properties in class above, write out properties
        //this is the header row
        sw.Write(string.Join(",", props.Select(d => d.Name).ToArray()) + newLine);

        //this acts as datarow
        foreach (T item in list)
        {
            //this acts as datacolumn
            var row = string.Join(",", props.Select(d => $"\"{item.GetType().GetProperty(d.Name).GetValue(item, null)?.ToString()}\"")
                                                    .ToArray());
            sw.Write(row + newLine);

        }
    }
}

Estimated execution plan

The estimated execution plan is generated by the Optimizer without running the SQL query.

In order to get the estimated execution plan, you need to enable the SHOWPLAN_ALL setting prior to executing the query.

SET SHOWPLAN_ALL ON

Now, when executing the following SQL query:

SELECT p.id
FROM post p
WHERE EXISTS (
  SELECT 1
  FROM post_comment pc
  WHERE
    pc.post_id = p.id AND
    pc.review = 'Bingo'
)
ORDER BY p.title
OFFSET 20 ROWS
FETCH NEXT 10 ROWS ONLY

SQL Server will generate the following estimated execution plan:

| NodeId | Parent | LogicalOp            | EstimateRows | EstimateIO  | EstimateCPU | AvgRowSize | TotalSubtreeCost | EstimateExecutions |
|--------|--------|----------------------|--------------|-------------|-------------|------------|------------------|--------------------|
| 1      | 0      | NULL                 | 10           | NULL        | NULL        | NULL       | 0.03374284       | NULL               |
| 2      | 1      | Top                  | 10           | 0           | 3.00E-06    | 15         | 0.03374284       | 1                  |

| 5      | 4      | Inner Join           | 46.698       | 0           | 0.00017974  | 146        | 0.02197446       | 1                  |
| 6      | 5      | Clustered Index Scan | 43           | 0.004606482 | 0.0007543   | 31         | 0.005360782      | 1                  |
| 7      | 5      | Clustered Index Seek | 1            | 0.003125    | 0.0001581   | 146        | 0.0161733        | 43                 |

After running the query we are interested in getting the estimated execution plan, you need to disable the SHOWPLAN_ALL as, otherwise, the current database session will only generate estimated execution plan instead of executing the provided SQL queries.

SET SHOWPLAN_ALL OFF

SQL Server Management Studio estimated plan

In the SQL Server Management Studio application, you can easily get the estimated execution plan for any SQL query by hitting the CTRL+L key shortcut.

Actual execution plan

The actual SQL execution plan is generated by the Optimizer when running the SQL query. If the database table statistics are accurate, the actual plan should not differ significantly from the estimated one.

To get the actual execution plan on SQL Server, you need to enable the STATISTICS IO, TIME, PROFILE settings, as illustrated by the following SQL command:

SET STATISTICS IO, TIME, PROFILE ON

Now, when running the previous query, SQL Server is going to generate the following execution plan:

| Rows | Executes | NodeId | Parent | LogicalOp            | EstimateRows | EstimateIO  | EstimateCPU | AvgRowSize | TotalSubtreeCost |
|------|----------|--------|--------|----------------------|--------------|-------------|-------------|------------|------------------|

If you know the name of the filters, you can do it in a line.

users = users.filter(obj => obj.name == filter.name && obj.address == filter.address)

I know this was answered a long time ago, but I've recently spent hours trying to solve a similar problem. The setup is local PC running Debian 8 using Eclipse CDT Neon.2, remote ARM7 board (Olimex) running Debian 7. Tool chain is Linaro 4.9 using gdbserver on the remote board and the Linaro GDB on the local PC. My issue was that the debug session would start and the program would execute, but breakpoints did not work and when manually paused "no source could be found" would result. My compile line options (Linaro gcc) included -ggdb -O0 as many have suggested but still the same problem. Ultimately I tried gdb proper on the remote board and it complained of no symbols. The curious thing was that 'file' reported debug not stripped on the target executable.

I ultimately solved the problem by adding -g to the linker options. I won't claim to fully understand why this helped, but I wanted to pass this on for others just in case it helps. In this case Linux did indeed need -g on the linker options.

Your code should like this:

<span id="replies">8</span>

var currentValue = $("#replies").text();
var newValue = parseInt(parseFloat(currentValue)) + 1;
$("replies").text(newValue);

Hacks N Tricks

You could skip the use of buttord, and instead just pick an order for the filter and see if it meets your filtering criterion. To generate the filter coefficients for a bandpass filter, give butter() the filter order, the cutoff frequencies Wn=[low, high] (expressed as the fraction of the Nyquist frequency, which is half the sampling frequency) and the band type btype="band".

Here's a script that defines a couple convenience functions for working with a Butterworth bandpass filter. When run as a script, it makes two plots. One shows the frequency response at several filter orders for the same sampling rate and cutoff frequencies. The other plot demonstrates the effect of the filter (with order=6) on a sample time series.

from scipy.signal import butter, lfilter


def butter_bandpass(lowcut, highcut, fs, order=5):
    nyq = 0.5 * fs
    low = lowcut / nyq
    high = highcut / nyq
    b, a = butter(order, [low, high], btype='band')
    return b, a


def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
    b, a = butter_bandpass(lowcut, highcut, fs, order=order)
    y = lfilter(b, a, data)
    return y


if __name__ == "__main__":
    import numpy as np
    import matplotlib.pyplot as plt
    from scipy.signal import freqz

    # Sample rate and desired cutoff frequencies (in Hz).
    fs = 5000.0
    lowcut = 500.0
    highcut = 1250.0

    # Plot the frequency response for a few different orders.
    plt.figure(1)

Here are the plots that are generated by this script:

There are a few problems here.

1: onBlur expects a callback, and you are calling renderPasswordConfirmError and using the return value, which is null.

2: you need a place to render the error.

3: you need a flag to track "and I validating", which you would set to true on blur. You can set this to false on focus if you want, depending on your desired behavior.

handleBlur: function () {
  this.setState({validating: true});
},
render: function () {
  return <div>
    ...
    <input
        type="password"
        placeholder="Password (confirm)"
        valueLink={this.linkState('password2')}
        onBlur={this.handleBlur}
     />
    ...
    {this.renderPasswordConfirmError()}
  </div>
},
renderPasswordConfirmError: function() {
  if (this.state.validating && this.state.password !== this.state.password2) {
    return (
      <div>
        <label className="error">Please enter the same password again.</label>
      </div>
    );
  }  
  return null;
},

pure javascript:

var ctrlKeyCode = 17;
var cntrlIsPressed = false;

document.addEventListener('keydown', function(event){
    if(event.which=="17")
        cntrlIsPressed = true;
});

document.addEventListener('keyup', function(){
    if(event.which=="17")
        cntrlIsPressed = true;
});



function selectMe(mouseButton)
{
    if(cntrlIsPressed)
    {
        switch(mouseButton)
        {
            case 1:
                alert("Cntrl +  left click");
                break;
            case 2:
                alert("Cntrl + right click");
                break;
            default:
                break;
        }
    }
}

You can use tool I've created to make this process easier: git-squash. For example to squash all commits on feature branch that has been branched from master branch, write:

git squash master
git push --force

count = max(enumerate(open(filename)))[0]

Open .dll file with visual studio. Or resource editor.

I would store the initial index during creation of the onClickListener object.

   int thisInitialIndex = 0;//change as needed

   myspinner.setSelection(thisInitialIndex);

   myspinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

      int initIndex = thisInitialIndex;

      @Override
      public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
         if (id != initIndex) { //if selectedIndex is the same as initial value
            // your real onselecteditemchange event
         }
      }

      @Override
      public void onNothingSelected(AdapterView<?> parent) {
      }
  });

If you are wondering where you can download the shared library (although this will not work on your client's devices unless you include the dll) here is the link: https://de.osdn.net/projects/mingw/downloads/72215/libgcc-9.2.0-1-mingw32-dll-1.tar.xz/

.zip    application/zip, application/octet-stream

A small addition to KTC's very informative main answer:

If you are using the free Visual Studio c++ 2010 Express, and managed to get that one to compile 64-bits binaries, and now want to use that to use a 64-bits version of the Boost libaries, you may end up with 32-bits libraries (your mileage may vary of course, but on my machine this is the sad case).

I could fix this using the following: inbetween the steps described above as

1. Start a 32-bit MSVC command prompt and change to the directory where Boost was unzipped.
2. Run: bootstrap

I inserted a call to 'setenv' to set the environment. For a release build, the above steps become:

1. Start a 32-bit MSVC command prompt and change to the directory where Boost was unzipped.
2. Run: "C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin\setenv.cmd" /Release /x64
3. Run: bootstrap

I found this info here: http://boost.2283326.n4.nabble.com/64-bit-with-VS-Express-again-td3044258.html

Here's one from jQuery Validate plugin's additional-methods.js file...

jQuery.validator.addMethod("zipUS", function(value, element) {
    return /(^\d{5}$)|(^\d{5}-\d{4}$)/.test(value);
}, "Please specify a valid US zip code.");

EDIT: Since the above code is part of the jQuery Validate plugin, it depends on the .addMethod() method.

Remove dependency on plugins and make it more generic....

function checkZip(value) {
    return (/(^\d{5}$)|(^\d{5}-\d{4}$)/).test(value);
};

Example Usage: http://jsfiddle.net/5PNcJ/

Some browsers (IIRC it is just some versions of Internet Explorer) only send the co-ordinates of the image map (in name.x and name.y) and ignore the value. This is a bug.

The workarounds are to either:

• Have only one submit button and use a hidden input to sent the value
• Use regular submit buttons instead of image maps
• Use unique names instead of values and check for the presence of name.x / name.y

This is a general solution to loading data into a C++ program, and uses the readline function. This could be modified for CSV files, but the delimiter is a space here.

int n = 5, p = 2;

int X[n][p];

ifstream myfile;

myfile.open("data.txt");

string line;
string temp = "";
int a = 0; // row index 

while (getline(myfile, line)) { //while there is a line
     int b = 0; // column index
     for (int i = 0; i < line.size(); i++) { // for each character in rowstring
          if (!isblank(line[i])) { // if it is not blank, do this
              string d(1, line[i]); // convert character to string
              temp.append(d); // append the two strings
        } else {
              X[a][b] = stod(temp);  // convert string to double
              temp = ""; // reset the capture
              b++; // increment b cause we have a new number
        }
    }

  X[a][b] = stod(temp);
  temp = "";
  a++; // onto next row
}

this is when you have one dictionary list:

import csv
with open('names.csv', 'w') as csvfile:
    fieldnames = ['first_name', 'last_name']
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
    writer.writeheader()
    writer.writerow({'first_name': 'Baked', 'last_name': 'Beans'})

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

if (listA.Except(listB).Any())

Check out LiquiBase for managing database changes using source control.

Yes, let's use Select as an example

sample code: Columns("A").select

How to loop through Columns:

Method 1: (You can use index to replace the Excel Address)

For i = 1 to 100
    Columns(i).Select
next i

Method 2: (Using the address)

For i = 1 To 100
 Columns(Columns(i).Address).Select
Next i

EDIT: Strip the Column for OP

columnString = Replace(Split(Columns(27).Address, ":")(0), "$", "")

e.g. you want to get the 27th Column --> AA, you can get it this way

As per the DOM structure you can use below code:

var x = document.getElementById('mySelect');
     var txt = "";
     var val = "";
     for (var i = 0; i < x.length; i++) {
         txt +=x[i].text + ",";
         val +=x[i].value + ",";
      }

Same basic solution as others, but I personally prefer to use map instead of the list comprehension:

>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(map(chr,L))
'hello, world'

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

For Red Hat :

sudo yum install libstdc++.i686
sudo yum install libstdc++-devel.i686

You should not use su in a dockerfile, however you should use the USER instruction in the Dockerfile.

At each stage of the Dockerfile build, a new container is created so any change you make to the user will not persist on the next build stage.

For example:

RUN whoami
RUN su test
RUN whoami

This would never say the user would be test as a new container is spawned on the 2nd whoami. The output would be root on both (unless of course you run USER beforehand).

If however you do:

RUN whoami
USER test
RUN whoami

You should see root then test.

Alternatively you can run a command as a different user with sudo with something like

sudo -u test whoami

But it seems better to use the official supported instruction.

"Sencha way" for interacting with server data is setting up an Ext.data.Store proxied by a Ext.data.proxy.Proxy (in this case Ext.data.proxy.Ajax) furnished with a Ext.data.reader.Json (for JSON-encoded data, there are other readers available as well). For writing data back to the server there's a Ext.data.writer.Writers of several kinds.

Here's an example of a setup like that:

    var store = Ext.create('Ext.data.Store', {
        fields: [
            'counter_name',
            'counter_type',
            'counter_unit'
        ],

        proxy: {
            type: 'ajax',
            url: 'data1.json',

            reader: {
                type: 'json',
                idProperty: 'counter_name',
                rootProperty: 'counters'
            }
        }
    });

data1.json in this example (also available in this fiddle) contains your data verbatim. idProperty: 'counter_name' is probably optional in this case but usually points at primary key attribute. rootProperty: 'counters' specifies which property contains array of data items.

With a store setup this way you can re-read data from the server by calling store.load(). You can also wire the store to any Sencha Touch appropriate UI components like grids, lists or forms.

If you don't want to use jQuery you can try this approach:

public setCaretPosition() {
    const editableDiv = document.getElementById('contenteditablediv');
    const lastLine = this.input.nativeElement.innerHTML.replace(/.*?(<br>)/g, '');
    const selection = window.getSelection();
    selection.collapse(editableDiv.childNodes[editableDiv.childNodes.length - 1], lastLine.length);
}

editableDiv you editable element, don't forget to set an id for it. Then you need to get your innerHTML from the element and cut all brake lines. And just set collapse with next arguments.

You could use this:

if k == int(k):
    print(str(k) + " is a whole number!")

It's simpler to use, the -a option :

cat ~/campaigns/release-status.html | mail -s "Release Status [Green]" -a "Content-Type: text/html" [email protected]

Define Methods like this and you will get the help you need.

    /// <summary>
    /// Adds two numbers and returns the result
    /// </summary>
    /// <param name="first">first number to add</param>
    /// <param name="second">second number to </param>
    /// <returns></returns>
    private int Add(int first, int second)
    {
        return first + second;
    }

Screenshot of the code usage

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

A simplification of Richard's solution. Works at least in Firefox, Safari and Opera:

<a href="..." style="display: block;">
    <object data="..." style="pointer-events: none;" />
</a>

The plus sign (+) before the resource type is needed only when you're defining a resource ID for the first time. When you compile the app, the SDK tools use the ID name to create a new resource ID in your project's R.java file that refers to the EditText element. With the resource ID declared once this way, other references to the ID do not need the plus sign. Using the plus sign is necessary only when specifying a new resource ID and not needed for concrete resources such as strings or layouts. See the sidebox for more information about resource objects.

I find it easier to pass a value as a temporal data type (e.g. DATETIME) then use temporal functionality, specifically DATEADD and DATEPART, to find the start and end dates for the period, in this case the month e.g. this finds the start date and end date pair for the current month, just substitute CURRENT_TIMESTAMP for you parameter of of type DATETIME (note the 1990-01-01 value is entirely arbitrary):

SELECT DATEADD(M, 
          DATEDIFF(M, '1990-01-01T00:00:00.000', CURRENT_TIMESTAMP), 
          '1990-01-01T00:00:00.000'), 
       DATEADD(M, 
          DATEDIFF(M, '1990-01-01T00:00:00.000', CURRENT_TIMESTAMP), 
          '1990-01-31T23:59:59.997')

As usual, VBScript is available for you to use.....

Set objFS = CreateObject("Scripting.FileSystemObject")
Set wshArgs = WScript.Arguments
strFile = wshArgs(0)
WScript.Echo objFS.GetFile(strFile).Size & " bytes"

Save as filesize.vbs and enter on the command-line:

C:\test>cscript /nologo filesize.vbs file.txt
79 bytes

Use a for loop (in batch) to get the return result.
