Programs & Examples On #Aggregateroot

The aggregate root is a complex name for a simple idea.

General idea

Well designed class diagram encapsulates its internals. Point through which you access this structure is called aggregate root.

Internals of your solution may be very complicated, but users of this hierarchy will just use root.doSomethingWhichHasBusinessMeaning().

Example

Check this simple class hierarchy

How do you want to ride your car? Chose better API

Option A (it just somehow works):

car.ride();

Option B (user has access to class inernals):

if(car.getTires().getUsageLevel()< Car.ACCEPTABLE_TIRE_USAGE)
    for (Wheel w: car:getWheels()){
        w.spin();
    }
}

If you think that option A is better then congratulations. You get the main reason behind aggregate root.

Aggregate root encapsulates multiple classes. you can manipulate the whole hierarchy only through the main object.

I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.

set codedirectory=C:\Users\code
for /r  %codedirectory% %%i in (*.c) do 
( some GCC commands )

select2 has the placeholder parameter. Use that one

$("#state").select2({
   placeholder: "Choose a Country"
 });

You can use .scrollIntoView() for this. It will bring a specific element into the viewport.

Example:

document.getElementById( 'bottom' ).scrollIntoView();

Demo: http://jsfiddle.net/ThinkingStiff/DG8yR/

Script:

function top() {
    document.getElementById( 'top' ).scrollIntoView();    
};

function bottom() {
    document.getElementById( 'bottom' ).scrollIntoView();
    window.setTimeout( function () { top(); }, 2000 );
};

bottom();

HTML:

<div id="top">top</div>
<div id="bottom">bottom</div>

CSS:

#top {
    border: 1px solid black;
    height: 3000px;
}

#bottom {
    border: 1px solid red;
}

I would use Android's AccountPicker, introduced in ICS.

Intent googlePicker = AccountPicker.newChooseAccountIntent(null, null, new String[]{GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE}, true, null, null, null, null);
startActivityForResult(googlePicker, REQUEST_CODE);

And then wait for the result:

protected void onActivityResult(final int requestCode, final int resultCode,
                                final Intent data) {
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
        String accountName = data.getStringExtra(AccountManager.KEY_ACCOUNT_NAME);
    }
}

I recommend to use Moment.js for such cases. I had scenarios where I had to check current date time, this week, this month and this quarters date time. Above an answer helped me so I thought to share rest of the functions as well.

Simply to get current date time in specific format

        case 'Today':
        moment().format("DD/MM/YYYY h:mm A");

        case 'This Week':
          moment().endOf('isoweek').format("DD/MM/YYYY h:mm A");

Week starts from Sunday and ends on Saturday if we simply use 'week' as parameter for endOf function but to get Sunday as the end of the week we need to use 'isoweek'.

        case 'This Month':
          moment().endOf('month').format("DD/MM/YYYY h:mm A");

        case 'This Quarter':
          moment().endOf('quarter').format("DD/MM/YYYY h:mm A");

I chose this format as per my need. You can change the format according to your requirement.

Array.prototype.find is not supported in any version of IE

It's probably just the order that C's readdir() returns. Try running this C program:

#include <dirent.h>
#include <stdio.h>
int main(void)
{   DIR *dirp;
    struct dirent* de;
    dirp = opendir(".");
    while(de = readdir(dirp)) // Yes, one '='.
        printf("%s\n", de->d_name);
    closedir(dirp);
    return 0;
}

The build line should be something like gcc -o foo foo.c.

P.S. Just ran this and your Python code, and they both gave me sorted output, so I can't reproduce what you're seeing.

Get-ChildItem "D:\Server\User\CUST\MEA\Data\In\Files\CORRECTED\CUST_MEAFile.csv"
|Select-Object -ExpandProperty Name

Maybe you should use shell commands. In Unix/Linux, find piped with sort will probably be able to do what you want.

Option 2 will work. You could also use a Set<Character> or

char[] myCharSet = new char[] {'A', 'B', 'C', ...};
Arrays.sort(myCharSet);
if (Arrays.binarySearch(myCharSet, symbol) >= 0) { ... }

Maybe using pytest_collect_file() hook you can parse the content of a .txt o .yaml file where the tests are specify as you want, and return them to the pytest core.

A nice example is shown in the pytest documentation. I think what you are looking for.

The preferred modern method is to use addEventListener either by adding the event listener direct to the element or to a parent of the elements (delegated).

An example, using delegated events, might be

var box = document.getElementById('box');_x000D_
_x000D_
document.getElementById('buttons').addEventListener('click', function(evt) {_x000D_
  var target = evt.target;_x000D_
  if (target.id === 'yes') {_x000D_
    box.style.backgroundColor = 'red';_x000D_
  } else if (target.id === 'no') {_x000D_
    box.style.backgroundColor = 'green';_x000D_
  } else {_x000D_
    box.style.backgroundColor = 'purple';_x000D_
  }_x000D_
}, false);

#box {_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  background-color: red;_x000D_
}_x000D_
#buttons {_x000D_
  margin-top: 50px;_x000D_
}

<div id='box'></div>_x000D_
<div id='buttons'>_x000D_
  <button id='yes'>yes</button>_x000D_
  <button id='no'>no</button>_x000D_
  <p>Click one of the buttons above.</p>_x000D_
</div>

This simple diagram that helps me to understand the difference between require and import.

Apart from that,

You can't selectively load only the pieces you need with require but with imports, you can selectively load only the pieces you need. That can save memory.

Loading is synchronous(step by step) for require on the other hand import can be asynchronous(without waiting for previous import) so it can perform a little better than require.

Ok, it seems that some versions of PHP have a limitation of length of GET params:

Please note that PHP setups with the suhosin patch installed will have a default limit of 512 characters for get parameters. Although bad practice, most browsers (including IE) supports URLs up to around 2000 characters, while Apache has a default of 8000.

To add support for long parameters with suhosin, add suhosin.get.max_value_length = <limit> in php.ini

The way you have written f it needs two inputs. If you look at the error message it says you are not providing two inputs to f, just one. The error message is correct.
The mismatch is because df[['col1','col2']] returns a single dataframe with two columns, not two separate columns.

You need to change your f so that it takes a single input, keep the above data frame as input, then break it up into x,y inside the function body. Then do whatever you need and return a single value.

You need this function signature because the syntax is .apply(f) So f needs to take the single thing = dataframe and not two things which is what your current f expects.

Since you haven't provided the body of f I can't help in anymore detail - but this should provide the way out without fundamentally changing your code or using some other methods rather than apply

@RequestParam makes Spring to map request parameters from the GET/POST request to your method argument.

GET Request

http://testwebaddress.com/getInformation.do?city=Sydney&country=Australia

public String getCountryFactors(@RequestParam(value = "city") String city, 
                    @RequestParam(value = "country") String country){ }

POST Request

@RequestBody makes Spring to map entire request to a model class and from there you can retrieve or set values from its getter and setter methods. Check below.

http://testwebaddress.com/getInformation.do

You have JSON data as such coming from the front end and hits your controller class

{
   "city": "Sydney",
   "country": "Australia"
}

Java Code - backend (@RequestBody)

public String getCountryFactors(@RequestBody Country countryFacts)
    {
        countryFacts.getCity();
        countryFacts.getCountry();
    }


public class Country {

    private String city;
    private String country;

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }
}

For those who tried gkalpak answer and it did not work,

be aware that chrome will add the content script to a needed page only when your extension enabled during chrome launch and also a good idea restart browser after making these changes

You could use the random.sample function from the standard library to select k elements from a population:

import random
random.sample(range(low, high), n)

In case of a rather large range of possible numbers, you could use itertools.islice with an infinite random generator:

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)
items = list(itertools.islice(gen, 10))  # Take first 10 random elements

After the question update it is now clear that you need n distinct (unique) numbers.

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)

items = set()

# Try to add elem to set until set length is less than 10
for x in itertools.takewhile(lambda x: len(items) < 10, gen):
    items.add(x)

You can use alias to improve the query:

UPDATE t1
   SET t1.Value = t2.Value
  FROM table1 AS t1
         INNER JOIN 
       table2 AS t2
         ON t1.ID = t2.ID

I created a Eclipse plugin, which can count the lines of source code. It support Kotlin, Java, Java Script, JSP, XML, C/C++, C#, and many other file types.

Please take a look at it. Any feedback would be appreciated!

the git-hub repository is here

In recent version, The following works fine:

    $('.selector').datetimepicker({
        maxDate: new Date()
    });

maxDate accepts a Date object as parameter.

The following found in documentation:

Multiple types supported:

• Date: A date object containing the minimum date.

• Number: A number of days from today. For example 2 represents two days from today and -1 represents yesterday.

• String: A string in the format defined by the dateFormat option, or a relative date. Relative dates must contain value and period pairs; valid periods are "y" for years, "m" for months, "w" for weeks, and "d" for days. For example, "+1m +7d" represents one month and seven days from today.

If you want to replace a single semicolon:

for i in range(0,len(line)):
 if (line[i]==";"):
     line = line[:i] + ":" + line[i+1:]

Havent tested it though.

Above answers are okay. But I have found a really nice option to use following in the view:

{{previous_info?.title}}

probably duplicated question Angular2 - error if don't check if {{object.field}} exists

For example:

map.panTo(new L.LatLng(40.737, -73.923));

Use material-design-icons-iconfont

Full disclosure, I'm the author of this package

Google's material-design-icons project is on low maintenance and out of date for a while. There's a gap between the version in https://material.io/icons/ and the version in material-design-icons.

I've created material-design-icons-iconfont to address these major issues:

• material-design-icons jams npm install - all irrelevant svg/xml/... files has been removed
• Font files are always up-to-date straight from Google Fonts CDN
• Support for scss

Install via npm

npm install material-design-icons-iconfont --save

It depends on how you pack your web application (webpack/gulp/bower/...), you'll need to import the .css/.scss file (and might change the relative fonts path)

Import Using SCSS

Import in one of your sass files

$material-design-icons-font-path: '~material-design-icons-iconfont/dist/fonts/';
@import '~material-design-icons-iconfont/src/material-design-icons';

Later on, reference your desired icon <i class="material-icons"> + icon-id + </i>

<i class="material-icons">contact_support</i>

• read the full instructions on material-design-icons-iconfont for more import methods

It comes with a light demo page to assist searching and copy-pasting fonts

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

The line #include "stdafx.h" must be the first line at the top of each source file, before any other header files are included.

If what you've shown is the entire .cxx file, then you did forget to include stdafx.h in that file.

Use the CSS3 Viewport-percentage feature.

Viewport-Percentage Explanation

Assuming you want the body width size to be a ratio of the browser's view port. I added a border so you can see the body resize as you change your browser width or height. I used a ratio of 90% of the view-port size.

I guess you have some conflict with other package. For me it was six. So you need to use a command like this:

pip install google-api-python-client --upgrade --ignore-installed six

or

pip install --ignore-installed six

Apache HttpClient doesn't know anything about JSON, so you'll need to construct your JSON separately. To do so, I recommend checking out the simple JSON-java library from json.org. (If "JSON-java" doesn't suit you, json.org has a big list of libraries available in different languages.)

Once you've generated your JSON, you can use something like the code below to POST it

StringRequestEntity requestEntity = new StringRequestEntity(
    JSON_STRING,
    "application/json",
    "UTF-8");

PostMethod postMethod = new PostMethod("http://example.com/action");
postMethod.setRequestEntity(requestEntity);

int statusCode = httpClient.executeMethod(postMethod);

Edit

Note - The above answer, as asked for in the question, applies to Apache HttpClient 3.1. However, to help anyone looking for an implementation against the latest Apache client:

StringEntity requestEntity = new StringEntity(
    JSON_STRING,
    ContentType.APPLICATION_JSON);

HttpPost postMethod = new HttpPost("http://example.com/action");
postMethod.setEntity(requestEntity);

HttpResponse rawResponse = httpclient.execute(postMethod);

Test if the object implements either java.util.Collection or java.util.Map. (Map has to be tested separately because it isn't a sub-interface of Collection.)

You can achieve this by adding border class of bootstrap

like for border left ,you can use border-left

working code

<div class="row">
    <div class="col-xs-6 col-sm-6 col-md-3 text-center leftspan border-right border-bottom" id="one"><h5>Rich Media Ad Production</h5><img src="images/richmedia.png"></div>

   /* 1 */ Foo* foo1 = new Foo ();

Creates an object of type Foo in dynamic memory. foo1 points to it. Normally, you wouldn't use raw pointers in C++, but rather a smart pointer. If Foo was a POD-type, this would perform value-initialization (it doesn't apply here).

   /* 2 */ Foo* foo2 = new Foo;

Identical to before, because Foo is not a POD type.

   /* 3 */ Foo foo3;

Creates a Foo object called foo3 in automatic storage.

   /* 4 */ Foo foo4 = Foo::Foo();

Uses copy-initialization to create a Foo object called foo4 in automatic storage.

   /* 5 */ Bar* bar1 = new Bar ( *new Foo() );

Uses Bar's conversion constructor to create an object of type Bar in dynamic storage. bar1 is a pointer to it.

   /* 6 */ Bar* bar2 = new Bar ( *new Foo );

Same as before.

   /* 7 */ Bar* bar3 = new Bar ( Foo foo5 );

This is just invalid syntax. You can't declare a variable there.

   /* 8 */ Bar* bar3 = new Bar ( Foo::Foo() );

Would work and work by the same principle to 5 and 6 if bar3 wasn't declared on in 7.

5 & 6 contain memory leaks.

Syntax like new Bar ( Foo::Foo() ); is not usual. It's usually new Bar ( (Foo()) ); - extra parenthesis account for most-vexing parse. (corrected)

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

Installing Android SDKs is done via the "Android SDK and AVD Manager"... there's a shortcut on Eclipse's "Window" menu, or you can run the .exe from the root of your existing Android SDK installation.

Yes I think installing the 2.3 SDK will fix your problem... you can install older SDKs at the same time. The important thing is that the structure of the SDK changed in 2.3 with some tools (such as ADB) moving from sdkroot\tools to sdkroot\platform-tools. Quite possibly the very latest ADT plugin isn't massively backwards-compatible re that change.

there are better ways to do it as mentioned on android developer sites http://developer.android.com/guide/topics/location/strategies.html

You could use Google Guava's:

If you know on what port it would be running(by default it would be 6379), you can use below command to get the pid of the process using that port and then can execute kill command for the same pid.

sudo lsof -i : <port> | awk '{print $2}'

the above command will give you pid.

kill <pid>;

This would shutdown your server.

If using TextBox2.Text as the source for a numeric value, it must first be checked to see if a value exists, and then converted to integer.

If the text box is blank when Convert.ToInt32 is called, you will receive the System.FormatException. Suggest trying:

protected void SetImageWidth()
{
   try{
      Image1.Width = Convert.ToInt32(TextBox1.Text);
   }
   catch(System.FormatException)
   {
      Image1.Width = 100; // or other default value as appropriate in context.
   }
}

Below code will delete the entire contents of artifact_path

- name: Clean artifact path
  file:
    state: absent
    path: "{{ artifact_path }}/"

Note: this will delete the directory too.

It's actually much easier with jQuery's promise API:

$.ajax(
            type: "GET",
            url: requestURL,
        ).then((success) =>
            console.dir(success)
        ).failure((failureResponse) =>
            console.dir(failureResponse)
        )

Alternatively, you can pass in of bind functions to each result callback; the order of parameters is: (success, failure). So long as you specify a function with at least 1 parameter, you get access to the response. So, for example, if you wanted to check the response text, you could simply do:

$.ajax(
            type: "GET",
            url: @get("url") + "logout",
            beforeSend: (xhr) -> xhr.setRequestHeader("token", currentToken)
        ).failure((response) -> console.log "Request was unauthorized" if response.status is 401

The proper way to install an MSI silently is via the msiexec.exe command line as follows:

 /QN = run completely silently
 /i = run install sequence 

There is a much more comprehensive answer here: Batch script to install MSI. This answer provides details on the msiexec.exe command line options and a description of how to find the "public properties" that you can set on the command line at install time. These properties are generally different for each MSI.

Nothing wrong with that implementation. You might give the yield keyword a shot, see how you like it:

private IEnumerable<TankReading> ConvertToTankReadings(DataTable dataTable)
    {
        foreach (DataRow row in dataTable.Rows)
        {
            yield return new TankReading
                                  {
                                      TankReadingsID = Convert.ToInt32(row["TRReadingsID"]),
                                      TankID = Convert.ToInt32(row["TankID"]),
                                      ReadingDateTime = Convert.ToDateTime(row["ReadingDateTime"]),
                                      ReadingFeet = Convert.ToInt32(row["ReadingFeet"]),
                                      ReadingInches = Convert.ToInt32(row["ReadingInches"]),
                                      MaterialNumber = row["MaterialNumber"].ToString(),
                                      EnteredBy = row["EnteredBy"].ToString(),
                                      ReadingPounds = Convert.ToDecimal(row["ReadingPounds"]),
                                      MaterialID = Convert.ToInt32(row["MaterialID"]),
                                      Submitted = Convert.ToBoolean(row["Submitted"]),
                                  };
        }

    }

Also the AsEnumerable isn't necessary, as List<T> is already an IEnumerable<T>

when you call in oncreate()

new LoginAsyncTask ().execute();

Here how to use in flow..

ProgressDialog progressDialog;

  private class LoginAsyncTask extends AsyncTask<Void, Void, Void> {
  @Override
    protected void onPreExecute() {
        progressDialog= new ProgressDialog(MainActivity.this);
        progressDialog.setMessage("Please wait...");
        progressDialog.show();
        super.onPreExecute();
    }

     protected Void doInBackground(Void... args) {
        // Parsse response data
        return null;
     }

     protected void onPostExecute(Void result) {
        if (progressDialog.isShowing())
                        progressDialog.dismiss();
        //move activity
        super.onPostExecute(result);
     }
 }

For example: Add this data-attr to your primary slick div: data-space="7"

                    $('[data-space]').each(function () {
                        var $this = $(this),
                            $space = $this.attr('data-space');

                        $('.slick-slide').css({
                            marginLeft: $space + 'px',
                            marginRight: $space + 'px'
                        });

                        $('.slick-list').css({
                            marginLeft: -$space + 'px',
                            marginRight: -$space/2 + 'px'
                        })
                    });

To answer your question: no, it's not possible to have multiple versions of IE (if that is what you meant) installed in a 'normal' way (i.e. not a hack, a sandbox or a VM etc). It's perfectly ok to have multiple browsers of different types installed on the same machine, such as IE8, Firefox 3 and Chrome all at once.

SandboxIE should allow you to install multiple versions of IE side-by-side (as well as other software), and this is less hassle than going down the virtual machine route.

However, from a QA point of view I'd strongly recommend installing different versions on different machines as the best option from a testing point of view. This will give you the most realistic testing environment. If you don't have the hardware for that, then virtual machines are the next best option as mentioned in some of the other answers.

import com.google.common.collect.Sets;
Sets.newHashSet("a", "b");

or

import com.google.common.collect.ImmutableSet;
ImmutableSet.of("a", "b");

I usually use

DATE_ADD(CURDATE(), INTERVAL - 1 MONTH)

Which is almost same as Pekka's but this way you can control your INTERVAL to be negative or positive...

Some PHP libraries can parse a SQL file made of multiple SQL statements, explode it properly (not using a simple ";" explode, naturally), and the execute them.

For instance, check Phing's PDOSQLExecTask

based on examples above and examples found on other sites, I created a generic procedure and some examples.

The solution provided by Rashack does not work for value types (int, enums, etc.) unfortunately.

For it to work with any type of property, this is the solution I found:

public static Expression<Func<T, object>> GetLambdaExpressionFor<T>(this string sortColumn)
    {
        var type = typeof(T);
        var parameterExpression = Expression.Parameter(type, "x");
        var body = Expression.PropertyOrField(parameterExpression, sortColumn);
        var convertedBody = Expression.MakeUnary(ExpressionType.Convert, body, typeof(object));

        var expression = Expression.Lambda<Func<T, object>>(convertedBody, new[] { parameterExpression });

        return expression;
    }

With SQL server you can just use a CTE instead of IF/THEN logic to make it easy to map from your existing queries and change the number of involved queries;

WITH cte AS (
    SELECT product,price,1 a FROM table1 WHERE project=1   UNION ALL
    SELECT product,price,2 a FROM table1 WHERE customer=2  UNION ALL
    SELECT product,price,3 a FROM table1 WHERE company=3
)
SELECT TOP 1 WITH TIES product,price FROM cte ORDER BY a;

An SQLfiddle to test with.

Alternately, you can combine it all into one SELECT to simplify it for the optimizer;

SELECT TOP 1 WITH TIES product,price FROM table1 
WHERE project=1 OR customer=2 OR company=3
ORDER BY CASE WHEN project=1  THEN 1 
              WHEN customer=2 THEN 2
              WHEN company=3  THEN 3 END;

Another SQLfiddle.

A one-line solution with data.table could be

library(data.table)
setDT(x)[,.N,by=Believe]
   Believe N
1:   FALSE 1
2:    TRUE 3

@@ is the escape character for @ in Razor views as stated above.

Razor does however try to work out when an '@' is just an '@' and where it marks C# (or VB.Net) code. One of the main uses for this is to identify email addresses within a Razor view - it should not be necessary to escape the @ character in an email address.

Mapping the WebDAV folder is my preferred method of creating an easily accessible, long-term connection to SharePoint. However, you'll find—even when properly mapped—that a file will return a URL when selected (especially via Application.FileDialog) due to changes in Windows 10 1803.

To circumvent this, you can map the drive using DriveMapper (or an equivalent) and then combine the resulting Application.FileDialog.SelectedItems with a URL to UNC converter function:

Public Function SharePointURLtoUNC( _
  sURL As String) _
As String
  Dim bIsSSL As Boolean

  bIsSSL = InStr(1, sURL, "https:") > 0
  sURL = Replace(Replace(sURL, "/", "\"), "%20", " ")
  sURL = Replace(Replace(sURL, "https:", vbNullString), "http:", vbNullString)
  
  sURL= Replace(sURL, Split(sURL, "\")(2), Split(sURL, "\")(2) & "@SSL\DavWWWRoot")
  If Not bIsSSL Then sURL = Replace(sURL, "@SSL\", vbNullString) 
  SharePointURLtoUNC = sURL
End Function

There are different ways of taking input in java like:

1) BufferedReader 2) Scanner 3) Command Line Arguments

BufferedReader Read text from a character-input stream, buffering characters so as to provide for the efficient reading of characters, arrays, and lines.

Where Scanner is a simple text scanner which can parse primitive types and strings using regular expressions.

if you are writing a simple log reader Buffered reader is adequate. if you are writing an XML parser Scanner is the more natural choice.

For more information please refer:

http://java.meritcampus.com/t/240/Bufferedreader?tc=mm69

If you download XML file and open it for example in Notepad++ you'll see that encoding is set to something else than UTF8 - I'v had the same problem with xml made myself, and it was just te encoding in the editor :)

String <?xml version="1.0" encoding="UTF-8"?> don't set up the encoding of the document, it's only info for validator or another resource.

There's always LINQ:

t.GetProperties().Where(
    p=>p.GetCustomAttributes(typeof(MyAttribute), true).Length != 0)

Below is some simple code to execute this:

sLocation = "D:\Excel-Fso.xls"
sTxtLocation = "D:\Excel-Fso.txt"
Set ObjExl = CreateObject("Excel.Application")
Set ObjWrkBk = ObjExl.Workbooks.Open(sLocation)
Set ObjWrkSht = ObjWrkBk.workSheets("Sheet1")
ObjExl.Visible = True
Set FSO = CreateObject("Scripting.FileSystemObject")
Set FSOFile = FSO.CreateTextFile (sTxtLocation)
sRowCnt = ObjWrkSht.usedRange.Rows.Count
sColCnt = ObjWrkSht.usedRange.Columns.Count
For iLoop = 1 to sRowCnt
  For jLoop = 1 to sColCnt 
    FSOFile.Write(ObjExl.Cells(iLoop,jLoop).value) & vbtab 
  Next
Next

Set ObjWrkBk = Nothing
Set ObjWrkSht = Nothing
Set ObjExl = Nothing
Set FSO = Nothing
Set FSOFile = Nothing

With MySQL 8.0+ you could use natively REGEXP_REPLACE function.

12.5.2 Regular Expressions:

REGEXP_REPLACE(expr, pat, repl[, pos[, occurrence[, match_type]]])

Replaces occurrences in the string expr that match the regular expression specified by the pattern pat with the replacement string repl, and returns the resulting string. If expr, pat, or repl is NULL, the return value is NULL.

and Regular expression support:

Previously, MySQL used the Henry Spencer regular expression library to support regular expression operators (REGEXP, RLIKE).

Regular expression support has been reimplemented using International Components for Unicode (ICU), which provides full Unicode support and is multibyte safe. The REGEXP_LIKE() function performs regular expression matching in the manner of the REGEXP and RLIKE operators, which now are synonyms for that function. In addition, the REGEXP_INSTR(), REGEXP_REPLACE(), and REGEXP_SUBSTR() functions are available to find match positions and perform substring substitution and extraction, respectively.

SELECT REGEXP_REPLACE('Stackoverflow','[A-Zf]','-',1,0,'c'); 
-- Output:
-tackover-low

In order to reset the value in angular 2 use:

this.rootNode.findNode("objectname").resetValue();

This is easy. Just grab your computer's IP address with IPconfig at the command prompt. Then, hit the service using the IP address rather than localhost. You don't need to do anything to Fiddler to make this work, it will just work by itself.

shareing for others:

read stream line by line,should be good for large files piped into stdin, my version:

var n=0;
function on_line(line,cb)
{
    ////one each line
    console.log(n++,"line ",line);
    return cb();
    ////end of one each line
}

var fs = require('fs');
var readStream = fs.createReadStream('all_titles.txt');
//var readStream = process.stdin;
readStream.pause();
readStream.setEncoding('utf8');

var buffer=[];
readStream.on('data', (chunk) => {
    const newlines=/[\r\n]+/;
    var lines=chunk.split(newlines)
    if(lines.length==1)
    {
        buffer.push(lines[0]);
        return;
    }   

    buffer.push(lines[0]);
    var str=buffer.join('');
    buffer.length=0;
    readStream.pause();

    on_line(str,()=>{
        var i=1,l=lines.length-1;
        i--;
        function while_next()
        {

@GáborNagy's comment on another post was the simplest solution I could find and worked like a charm for me, since he brought a jsfiddle I'm copying it here with a small addition:

CSS:

#wrapper {
    display: table;
    height: 150px;
    width: 800px;
    border: 1px solid red;
}

#cell {
    display: table-cell;
    vertical-align: middle;
}

HTML:

<div id="wrapper">
    <div id="cell">
        <div class="content">
            Content goes here
        </div>
    </div>
</div>

If you wish to also align it horizontally you'd have to add another div "inner-cell" inside the "cell" div, and give it this style:

#inner-cell{
      width: 250px;
      display: block;
      margin: 0 auto;
}

>>> s = 'my string with \\"double quotes\\" blablabla'
>>> s
'my string with \\"double quotes\\" blablabla'
>>> print s
my string with \"double quotes\" blablabla
>>> 

When you just ask for 's' it escapes the \ for you, when you print it, you see the string a more 'raw' state. So now...

>>> s = """my string with "double quotes" blablabla"""
'my string with "double quotes" blablabla'
>>> print s.replace('"', '\\"')
my string with \"double quotes\" blablabla
>>> 

Try this:

function btnClick() {
    var x = document.getElementById("mytable").getElementsByTagName("td");
    x[0].innerHTML = "i want to change my cell color";
    x[0].style.backgroundColor = "yellow";            
}

Set from JS, backgroundColor is the equivalent of background-color in your style-sheet.

Note also that the .cells collection belongs to a table row, not to the table itself. To get all the cells from all rows you can instead use getElementsByTagName().

I had the same problem. in Intellj, when i want to use h2 database when my program was running i got the same error. For solve this problem i changed the connection url from

spring.datasource.url=jdbc:h2:file:~/ipinbarbot

to:

spring.datasource.url=jdbc:h2:~/ipinbarbot;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE

And then my problem gone away. now i can connect to "ipinbarbot" database when my program is. If you use Hibernate, also don't forget to have:

spring.jpa.hibernate.ddl-auto = update

android:textStyle="bold" //only bold
android:textStyle="italic" //only italic
android:textStyle="bold|italic" //bold & italic

You can only use specific fonts sans, serif & monospace via xml, Java code can use custom fonts

android:typeface="monospace" // or sans or serif

Programmatically (Java code)

TextView textView = (TextView) findViewById(R.id.TextView1);

textView.setTypeface(Typeface.SANS_SERIF); //only font style
textView.setTypeface(null,Typeface.BOLD); //only text style(only bold)
textView.setTypeface(null,Typeface.BOLD_ITALIC); //only text style(bold & italic)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD); 
                                         //font style & text style(only bold)
textView.setTypeface(Typeface.SANS_SERIF,Typeface.BOLD_ITALIC);
                                         //font style & text style(bold & italic)

I encountered the same problem, just sharing what I found out. Might help you and others...

Try this on your layout.add the line below in your EditText.

android:inputType="textCapWords|textCapSentences"

works fine on me.. hope it works also on you...

you can use show instead of shown for making the function to load just before modal open, instead of after modal open.

$('#code').on('show.bs.modal', function (e) {
  // do something...
})

Python suggests users use len() instead of __len__() for consistency, just like other guys said. However, There're some other benefits:

For some built-in types like list, str, bytearray and so on, the Cython implementation of len() takes a shortcut. It directly returns the ob_size in a C structure, which is faster than calling __len__().

If you are interested in such details, you could read the book called "Fluent Python" by Luciano Ramalho. There're many interesting details in it, and may help you understand Python more deeply.

You could also get the error if your Billing is not set up correctly.

Google hands out credit worth $300 or 12 months of free usage whichever runs out faster. After that you would need to enable billing.

You are looking for an sprintf implementation for JavaScript, so that you can write out floats with small errors in them (since they are stored in binary format) in a format that you expect.

Try javascript-sprintf, you would call it like this:

var yourString = sprintf("%.2f", yourNumber);

to print out your number as a float with two decimal places.

You may also use Number.toFixed() for display purposes, if you'd rather not include more files merely for floating point rounding to a given precision.

This is tricky; the reason it's failing is that you can't position via margin or text-align while absolutely positioned.

If the image is alone in the div, then I recommend something like this:

.image_block {
    width: 175px;
    height: 175px;
    line-height: 175px;
    text-align: center;
    vertical-align: bottom;
}

You may need to stick the vertical-align call on the image instead; not really sure without testing it. Using vertical-align and line-height is going to treat you a lot better, though, than trying to mess around with absolute positioning.

A snippet out of the MSDN:

'The following code sample shows how to create a DateTimePicker that enables users to choose a time only.'

timePicker = new DateTimePicker();
timePicker.Format = DateTimePickerFormat.Time;
timePicker.ShowUpDown = true;

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

String str_date="13-09-2011";
DateFormat formatter ; 
Date date ; 
formatter = new SimpleDateFormat("dd-MM-yyyy");
date = (Date)formatter.parse(str_date); 
System.out.println("Today is " +date.getTime());

Try this

Do not use floats to store fixed-point, accuracy-required data. This example shows how to convert a float to NVARCHAR(50) properly, while also showing why it is a bad idea to use floats for precision data.

create table #f ([Column_Name] float)
insert #f select 9072351234
insert #f select 907235123400000000000

select
    cast([Column_Name] as nvarchar(50)),
    --cast([Column_Name] as int), Arithmetic overflow
    --cast([Column_Name] as bigint), Arithmetic overflow
    CAST(LTRIM(STR([Column_Name],50)) AS NVARCHAR(50))
from #f

Output

9.07235e+009    9072351234
9.07235e+020    907235123400000010000

You may notice that the 2nd output ends with '10000' even though the data we tried to store in the table ends with '00000'. It is because float datatype has a fixed number of significant figures supported, which doesn't extend that far.

tl;dr the "standards" are a hodge-podge mess; it depends who you ask!

Overall, there appears to be no MIME type image/jpg. Yet, in practice, nearly all software handles image files named "*.jpg" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg could be many different things.

For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.

• sitepoint.com mime-types-complete-list (archived)
  • .jfif, .jfif-tbnl, .jpe, .jpeg, .jpg ? image/jpeg
  • .jfif, .jpe, .jpeg, .jpg ? image/pjpeg
• freeformatter.com mime-types (archived)
  • .jpeg, .jpg ? image/jpeg
  • .jpeg, .jpg ? image/x-citrix-jpeg
  • .pjpeg ? image/pjpeg
• IANA "Media Types" (formerly known as MIME types) lists (archived)
  (this document lists "names", not "file name extensions")
  • jpg not mentioned
  • jpeg ? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg¹³
  • JPEG ? video/JPEG
  • jpeg2000 ? video/jpeg2000
  • jpm ? image/jpm (JPEG 2000)
  • jpx ? image/jpx (JPEG 2000)
  • vnd.sealedmedia.softseal.jpg ? image/vnd.sealedmedia.softseal.jpg
• RFC 3745 MIME Type Registrations for JPEG 2000 (ISO/IEC 15444)
  • .jpg file extension not mentioned
  • .jpeg file extension not mentioned
  • .jp2, .jpg2 ? image/jp2 (JPEG 2000)⁹
  • .jpf, .jpx ? image/jpx (JPEG 2000 ISO-JPEG2000-2 encoded image data)¹⁰
  • .mj2, .mjp2 ? video/mj2 (Motion JPEG 2000)¹¹
  • .jpm, .jpgm ? image/jpm (JPEG 2000 profiles and extensions)¹²

These "complete lists" and RFC do not have MIME type image/jpg! But for MIME type image/jpeg some lists do have varying file name extensions (.jpeg, .jpg, …). Other lists do not mention image/jpeg.

Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.

Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf is preferred file extension for image/jpx but in IANA Media Types the name jpf is not present (and that IANA document references RFC 3745!).

Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.

Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?

The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg yet there exists the odd vnd.sealedmedia.softseal.jpg. File extension.JPEG is only known as a video type while file extension .jpeg is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000 is type video yet RFC 3745 considers JPEG 2000 an image type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg).

Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

Related question "List of ALL MimeTypes on the Planet, mapped to File Extensions?".

Try

L.replaceAll("(\\t|\\r?\\n)+", " ");

Depending on the system a linefeed is either \r\n or just \n.

Simple:

#include <stdexcept>

int compare( int a, int b ) {
    if ( a < 0 || b < 0 ) {
        throw std::invalid_argument( "received negative value" );
    }
}

The Standard Library comes with a nice collection of built-in exception objects you can throw. Keep in mind that you should always throw by value and catch by reference:

try {
    compare( -1, 3 );
}
catch( const std::invalid_argument& e ) {
    // do stuff with exception... 
}

You can have multiple catch() statements after each try, so you can handle different exception types separately if you want.

You can also re-throw exceptions:

catch( const std::invalid_argument& e ) {
    // do something

    // let someone higher up the call stack handle it if they want
    throw;
}

And to catch exceptions regardless of type:

catch( ... ) { };

You can assign an initial value to a new DateTime value in many different ways:

• Extension Method

Extension method DateTime

    public static DateTime ChangeTime(this DateTime dateTime, int hours, int minutes, int seconds = default, int milliseconds = default)
    {
        return new DateTime(dateTime.Year, dateTime.Month, dateTime.Day, hours, minutes, seconds, milliseconds, dateTime.Kind);
    }

then using ChangeTime:

    DateTime datetime = DateTime.Now; //Your DateTime
    datetime = datetime.ChangeTime(12, 20, 10);

• using the Add methods

  DateTime datetime = DateTime.Now; //Your DateTime
  datetime = datetime.Date.AddHours(12).AddMinutes(20).AddSeconds(10);
  

• using the Timespan

  DateTime datetime = DateTime.Now; //Your DateTime
  datetime = datetime.Date.Add(new TimeSpan(12, 20, 10));
  

• using initial value

  DateTime datetime = DateTime.Now;
  datetime = new DateTime(datetime.Year, datetime.Month, datetime.Day, 12, 20, 10);
  

These helped me a lot: I wanted to save values from my gridview, and it was reloading my gridview /overriding my new values, as i have IsPostBack inside my PageLoad.

if (HttpContext.Current.Request["MYCLICKEDBUTTONID"] == null)
{
   //Do not reload the gridview.

}
else
{
   reload my gridview.
}

You can use the comparison operators to compare strings. A strcmp function could be defined like this:

function strcmp(a, b) {
    if (a.toString() < b.toString()) return -1;
    if (a.toString() > b.toString()) return 1;
    return 0;
}

Edit    Here’s a string comparison function that takes at most min { length(a), length(b) } comparisons to tell how two strings relate to each other:

function strcmp(a, b) {
    a = a.toString(), b = b.toString();
    for (var i=0,n=Math.max(a.length, b.length); i<n && a.charAt(i) === b.charAt(i); ++i);
    if (i === n) return 0;
    return a.charAt(i) > b.charAt(i) ? -1 : 1;
}

Today my colleague stumbled upon the same issue.

As the "margin:0" solution works for chromium based browsers, however, Internet Explorer continue to print footer even if @page margins are set to zero.

The solution (more of a hack) was to put negative margin on the @page.

@page {margin:0 -6cm}
html {margin:0 6cm}

Please note that negative margin won't work for Y axis, only for X

Hope it helps.

While there are several excellent answers, ranging from usual suspects to newer solutions, I would like to provide one more to the fray that addresses what you should do when you are working on a solution with multiple projects.

Before I arrived at this solution, I kept looking at bindingInformation in the applicationhost.config of the solution, tirelessly looking for any hint of why things were simply not working.

Turns out, the simple thing that I overlooked was that different projects have individual settings too.

So, besides Project > {Project-Name} Properties... > Web > Start Action on my Backend Project, I also had to Go to Website > Start Options... > Start Action on my Frontend Project. Once there, I selected Don't open a page. Wait for a request from an external application and have been happy ever since!

Html code:

Change Title:
<input type="text" id="changeTitle" placeholder="Enter title tag">
<button id="changeTitle1">Click!</button>

Jquery code:

$(document).ready(function(){   
    $("#changeTitle1").click(function() {
        $(document).prop('title',$("#changeTitle").val()); 
    });
});

For us the problem was happening randomly only in the production environment. The RegisterForEventValidation did nothing for us.

Finally, we figured out that the web farm in which the asp.net app was running, two IIS servers had different .net versions installed. So it appears they had different rules for encrypting the asp.net validation hash. Updating them solved most of the problem.

Also, we configured the machineKey(compatibilityMode) (the same in both servers), httpRuntime(targetFramework), ValidationSettings:UnobtrusiveValidationMode, pages(renderAllHiddenFieldsAtTopOfForm) in the web.config of both servers.

We used this site to generate the key https://www.allkeysgenerator.com/Random/ASP-Net-MachineKey-Generator.aspx

We spent a lot of time solving this, I hope this helps somebody.

<appSettings>
   <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
...
</appSettings>
<system.web>
   <machineKey compatibilityMode="Framework45" decryptionKey="somekey" validationKey="otherkey" validation="SHA1" decryption="AES />
   <pages [...] controlRenderingCompatibilityVersion="4.0" enableEventValidation="true" renderAllHiddenFieldsAtTopOfForm="true" />
   <httpRuntime [...] requestValidationMode="2.0" targetFramework="4.5" />

3. Finally jWplayer is used to play the video on a webpage.

To add a button programatically to your controller's view, use the following:

-(void)viewDidLoad
{
   UIButton * btn = [UIButton buttonWithType:UIButtonTypeRoundedRect];
   btn.frame = CGRectMake(0, 0, 100, 50);
   [btn setTitle:@"Hello, world!" forState:UIControlStateNormal];
   [self.view addSubview:btn];
}

To add three of these, rinse and repeat.

You can use inner divs to set the margin.

<div style="display: table-cell;">
   <div style="margin:5px;background-color: red;">1</div>
</div>
<div style="display: table-cell; ">
  <div style="margin:5px;background-color: green;">1</div>
</div>

JS Fiddle

Our variable:

Map<String, List<Integer>> map = new HashMap<String, List<Integer>>();

To store:

map.put("mango", new ArrayList<Integer>(Arrays.asList(0, 4, 8, 9, 12)));

To add numbers one and one, you can do something like this:

String key = "mango";
int number = 42;
if (map.get(key) == null) {
    map.put(key, new ArrayList<Integer>());
}
map.get(key).add(number);

In Java 8 you can use putIfAbsent to add the list if it did not exist already:

map.putIfAbsent(key, new ArrayList<Integer>());
map.get(key).add(number);

Use the map.entrySet() method to iterate on:

for (Entry<String, List<Integer>> ee : map.entrySet()) {
    String key = ee.getKey();
    List<Integer> values = ee.getValue();
    // TODO: Do something.
}

In order to compare two databases, I've written the procedures bellow. If you want to compare two tables you can use procedure 'CompareTables'. Example :

EXEC master.dbo.CompareTables 'DB1', 'dbo', 'table1', 'DB2', 'dbo', 'table2'

If you want to compare two databases, use the procedure 'CompareDatabases'. Example :

EXEC master.dbo.CompareDatabases 'DB1', 'DB2'

Note : - I tried to make the procedures secure, but anyway, those procedures are only for testing and debugging. - If you want a complete solution for comparison use third party like (Visual Studio, ...)

int[] arr = new int[10];

arr is an int type array which has size 10. It is an array of 10 elements. If we don't initialize an array by default array elements contains default value. In case of int array default value is 0.

length is a property which is applicable for an array.
here arr.length will give 10.

You can use round function

round("10.221",2);

Will return 10.22

You can use arrows:

I think that depends on your window manager.

I'm a windows user, so this might be a wrong guess, but: Isn't there something called X-Server running on linux machines - at least on ones that might be interesting targets for VNC - that you can connect to with "X-Clients"?

VNC just takes everything that's on the screen and "tunnels it through your network". If I'm not totally wrong then the "X" protocol should give you the chance to use your client's desktop resolution.

Give X-Server on Wikipedia a try, that might give you a rough overview.

A bit late, but I just stumbled across the same problem while trying to provide analytics for my web app that involved sending app version based on the package.json version.

Configuration is as follows: React + Redux, Webpack 3.5.6

The json-loader isn't doing much since Webpack 2+, so after some fiddling with it, I ended up removing it.

The solution that actually worked for me, was simply using fetch. While this will most probably enforce some code changes to adapt to the async approach, it worked perfectly, especially given the fact that fetch will offer json decoding on the fly.

So here it is:

  fetch('../../package.json')
  .then(resp => resp.json())
  .then((packageJson) => {
    console.log(packageJson.version);
  });

Do keep in mind, that since we're talking about package.json specifically here, the file will not usually come bundled in your production build (or even dev for that matter), so you will have to use the CopyWebpackPlugin to have access to it when using fetch.

Use the pandas.DataFrame.round() method like this:

df = df.round({'value1': 0})

Any columns not included will be left as is.

I found I COULD use "if-then" statements in a lambda. For instance:

eval_op = {
    '|'  : lambda x,y: eval(y) if (eval(x)==0) else eval(x),
    '&'  : lambda x,y: 0 if (eval(x)==0) else eval(y),
    '<'  : lambda x,y: 1 if (eval(x)<eval(y)) else 0,
    '>'  : lambda x,y: 1 if (eval(x)>eval(y)) else 0,
}

Maybe off-topic, but R features two nice, fast and empty-aware functions for reducing logical vectors -- any and all:

if(any(x=='dolphin')) stop("Told you, no mammals!")

You need to use ECHO. Also, put the quotes around the entire file path if it contains spaces.

One other note, use > to overwrite a file if it exists or create if it does not exist. Use >> to append to an existing file or create if it does not exist.

Overwrite the file with a blank line:

ECHO.>"C:\My folder\Myfile.log"

Append a blank line to a file:

ECHO.>>"C:\My folder\Myfile.log"

Append text to a file:

ECHO Some text>>"C:\My folder\Myfile.log"

Append a variable to a file:

ECHO %MY_VARIABLE%>>"C:\My folder\Myfile.log"

OK, so within minutes after posting the question, I found the answer myself here: https://github.com/npm/npm/issues/2119#issuecomment-5321857

The issue seems to be that npm is not that great with HTTPS over a proxy. Changing the registry URL from HTTPS to HTTP fixed it for me:

npm config set registry http://registry.npmjs.org/

I still have to provide the proxy config (through Authoxy in my case), but everything works fine now.

Seems to be a common issue, but not well documented. I hope this answer here will make it easier for people to find if they run into this issue.

Procedural Implementation of Marc B's Answer after refining Sergey Telshevsky's Answer.

function strip_param_from_url( $url, $param )
{
    $base_url = strtok($url, '?');              // Get the base url
    $parsed_url = parse_url($url);              // Parse it 
    $query = $parsed_url['query'];              // Get the query string
    parse_str( $query, $parameters );           // Convert Parameters into array
    unset( $parameters[$param] );               // Delete the one you want
    $new_query = http_build_query($parameters); // Rebuilt query string
    return $base_url.'?'.$new_query;            // Finally url is ready
}

// Usage
echo strip_param_from_url( 'http://url.com/search/?location=london&page_number=1', 'location' )

You need to set the error_reporting value in a .htaccess file. Since there is a parse error, it never runs the error_reporting() function in your PHP code.

Try this in a .htaccess file (assuming you can use one):

php_flag display_errors 1
php_value error_reporting 30719

I think 30719 corresponds to E_ALL but I may be wrong.

Edit Update: http://php.net/manual/en/errorfunc.constants.php

int error_reporting ([ int $level ] )
---
32767   E_ALL (integer)     
All errors and warnings, as supported, except of   level E_STRICT prior to PHP 5.4.0.   32767 in PHP 5.4.x, 30719 in PHP 5.3.x, 6143 in PHP   5.2.x, 2047 previously

John is an optional Person, meaning it can hold a value or be nil.

john.apartment = number73

is used if john is not an optional. Since john is never nil we can be sure it won't call apartment on a nil value. While

john!.apartment = number73

promises the compiler that john is not nil then unwraps the optional to get john's value and accesses john's apartment property. Use this if you know that john is not nil. If you call this on a nil optional, you'll get a runtime error.

The documentation includes a nice example for using this where convertedNumber is an optional.

if convertedNumber {
    println("\(possibleNumber) has an integer value of \(convertedNumber!)")
} else {
    println("\(possibleNumber) could not be converted to an integer")
}

I hope this complete example will help you.

This is the TaxiInfo class which holds information about a taxi ride:

namespace Taxi.Models
{
    public class TaxiInfo
    {
        public String Driver { get; set; }
        public Double Fare { get; set; }
        public Double Distance { get; set; }
        public String StartLocation { get; set; }
        public String EndLocation { get; set; }
    }
}

We also have a convenience model which holds a List of TaxiInfo(s):

namespace Taxi.Models
{
    public class TaxiInfoSet
    {
        public List<TaxiInfo> TaxiInfoList { get; set; }

        public TaxiInfoSet(params TaxiInfo[] TaxiInfos)
        {
            TaxiInfoList = new List<TaxiInfo>();

            foreach(var TaxiInfo in TaxiInfos)
            {
                TaxiInfoList.Add(TaxiInfo);
            }
        }
    }
}

Now in the home controller we have the default Index action which for this example makes two taxi drivers and adds them to the list contained in a TaxiInfo:

public ActionResult Index()
{
    var taxi1 = new TaxiInfo() { Fare = 20.2, Distance = 15, Driver = "Billy", StartLocation = "Perth", EndLocation = "Brisbane" };
    var taxi2 = new TaxiInfo() { Fare = 2339.2, Distance = 1500, Driver = "Smith", StartLocation = "Perth", EndLocation = "America" };

    return View(new TaxiInfoSet(taxi1,taxi2));
}

The code for the view is as follows:

@model Taxi.Models.TaxiInfoSet
@{
    ViewBag.Title = "Index";
}

<h2>Index</h2>

@foreach(var TaxiInfo in Model.TaxiInfoList){
    <form>
        <h1>Cost: [email protected]</h1>
        <h2>Distance: @(TaxiInfo.Distance) km</h2>
        <p>
            Our diver, @TaxiInfo.Driver will take you from @TaxiInfo.StartLocation to @TaxiInfo.EndLocation
        </p>
        @Html.ActionLink("Home","Booking",TaxiInfo)
    </form>
}

The ActionLink is responsible for the re-directing to the booking action of the Home controller (and passing in the appropriate TaxiInfo object) which is defiend as follows:

    public ActionResult Booking(TaxiInfo Taxi)
    {
        return View(Taxi);
    }

This returns a the following view:

@model Taxi.Models.TaxiInfo

@{
    ViewBag.Title = "Booking";
}

<h2>Booking For</h2>
<h1>@Model.Driver, going from @Model.StartLocation to @Model.EndLocation (a total of @Model.Distance km) for [email protected]</h1>

A visual tour:

You shouldn't launch as an IIS server. check your launch setting, make sure it switched to your project name( change this name in your launchSettings.json file ), not the IIS.

Another java 8 lambda option :

String[] array2 = Arrays.stream(array).map(String::trim).toArray(String[]::new);

And the ugly but optimized version without new array creation

Arrays.stream(array).map(String::trim).toArray(unused -> array);

Original "array" is modified.

In C, Pass-by-reference is simulated by passing the address of a variable (a pointer) and dereferencing that address within the function to read or write the actual variable. This will be referred to as "C style pass-by-reference."

If you are on windows then below port related server settings are present in file nginx.conf at < nginx installation path >/conf folder.

server {
    listen       80;

Change the port number and restart the instance.

For SumUp Users, if you are loading the latest SumUpSDK.xcFramework, then you need to make sure that it's set to "Embed & Sign" from the application's General tab of the Target.

i.e. to reverse the above statement (making it easier to understand):

1. Go to the "Project Navigator" (i.e. the first icon to show all project items etc)

2. Select your project from the top of the tree.

3. On the menu in the middle of the page (slightly to the right), select your application under "Targets"

4. From the top-tab, select "General"

5. Scroll down to "Frameworks, Libraries and Embedded Content"

6. Select your Lib from the list

7. Select "Embed & Sign" from the drop down list next to it.

8. Clean

9. Re-Build and run.

I hope this helps.

Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

Their are quite trick solution for this and leak of fragment from activity.

So in case of getResource or anything one which is depending on activity context accessing from Fragment it is always check activity status and fragments status as follows

 Activity activity = getActivity(); 
    if(activity != null && isAdded())

         getResources().getString(R.string.no_internet_error_msg);
//Or any other depends on activity context to be live like dailog


        }
    }

Here's another suggestion:

public interface Service<T> {
   T execute();
}

using this simple interface you can pass arguments via constructor in the concrete service classes:

public class FooService implements Service<String> {

    private final String input1;
    private final int input2;

    public FooService(String input1, int input2) {
       this.input1 = input1;
       this.input2 = input2;
    }

    @Override
    public String execute() {
        return String.format("'%s%d'", input1, input2);
    }
}

Create repository on dockerhub :

$docker tag IMAGE_ID UsernameOnDockerhub/repoNameOnDockerhub:latest

$docker push UsernameOnDockerhub/repoNameOnDockerhub:latest

Note : here "repoNameOnDockerhub" : repository with the name you are mentioning has to be present on dockerhub

"latest" : is just tag

You need a library that can encrypt your input on client side and transfer it to the server in encrypted form.

You can use following libs:

• jCryption. Client-Server asymmetric encryption over Javascript

Update after 3 years (2013):

• Stanford Javascript Crypto Library

Update after 4 years (2014):

• CryptoJS - Easy to use encryption
• ForgeJS - Pretty much covers it all
• OpenPGP.JS - Put the OpenPGP format everywhere - runs in JS so you can use it in your web apps, mobile apps & etc.

'a' in vars() or 'a' in globals()

if you want to be pedantic, you can check the builtins too
'a' in vars(__builtins__)

Use

p.setval(static_cast<const char *>(0));

or

p.setval(static_cast<unsigned int>(0));

As indicated by the error, the type of 0 is int. This can just as easily be cast to an unsigned int or a const char *. By making the cast manually, you are telling the compiler which overload you want.

I had a special case of this: I had a file with --assume-unchanged on it. It was hard to locate, as the git status command was not showing any changes

This error will also appear if you try to connect to an exposed port from within a Docker container, when nothing is actively serving the port.

On a host where nothing is listening/bound to that port you'd get a No connection could be made because the target machine actively refused it error instead when making a request to a local URL that is not served, eg: localhost:5000. However, if you start a container that binds to the port, but there is no server running inside of it actually serving the port, any requests to that port on localhost will result in:

• [Errno 99] Cannot assign requested address (if called from within the container), or
• [Errno 0] Error (if called from outside of the container).

You can reproduce this error and the behaviour described above as follows:

Start a dummy container (note: this will pull the python image if not found locally):

docker run --name serv1 -p 5000:5000 -dit python

Then for [Errno 0] Error enter a Python console on host, while for [Errno 99] Cannot assign requested address access a Python console on the container by calling:

docker exec -it -u 0 serv1 python

And then in either case call:

import urllib.request
urllib.request.urlopen('https://localhost:5000')

I concluded with treating either of these errors as equivalent to No connection could be made because the target machine actively refused it rather than trying to fix their cause - although please advise if that's a bad idea.

I've spent over a day figuring this one out, given that all resources and answers I could find on the [Errno 99] Cannot assign requested address point in the direction of binding to an occupied port, connecting to an invalid IP, sysctl conflicts, docker network issues, TIME_WAIT being incorrect, and many more things. Therefore I wanted to leave this answer here, despite not being a direct answer to the question at hand, given that it can be a common cause for the error described in this question.

Make sure this is not code smell. Is it possible to reverse the logic and be 'inclusive' rather than 'exclusive'?

List<String> names = ....
List<String> reducedNames = ....
for (String name : names) {
   // Do something
   if (conditionToIncludeMet)
       reducedNames.add(name);
}
return reducedNames;

The situation that led me to this page involved old code that looped through a List using indecies to remove elements from the List. I wanted to refactor it to use the foreach style.

It looped through an entire list of elements to verify which ones the user had permission to access, and removed the ones that didn't have permission from the list.

List<Service> services = ...
for (int i=0; i<services.size(); i++) {
    if (!isServicePermitted(user, services.get(i)))
         services.remove(i);
}

To reverse this and not use the remove:

List<Service> services = ...
List<Service> permittedServices = ...
for (Service service:services) {
    if (isServicePermitted(user, service))
         permittedServices.add(service);
}
return permittedServices;

When would "remove" be preferred? One consideration is if gien a large list or expensive "add", combined with only a few removed compared to the list size. It might be more efficient to only do a few removes rather than a great many adds. But in my case the situation did not merit such an optimization.

You can use scriptlets, however, this is not the way to go. Nowdays inline scriplets or JAVA code in your JSP files is considered a bad habit.

You should read up on JSTL a bit more. If the ansokanInfo object is in your request or session scope, printing the object (toString() method) like this: ${ansokanInfo} can give you some base information. ${ansokanInfo.pSystem} should call the object getter method. If this all works, you can use this:

<c:if test="${ ansokanInfo.pSystem  == 'NAT'}"> tataa </c:if>

I know this is a very old thread, but it is the top google search for this error, and none of the responses mention a common cause of the error.

Which is closing a file you've already closed.

If you're not paying attention and have two different functions close the same file, then the second one will generate this error.

After a lot of try I resolved this with following steps:

 0. Run `cmd` or `powershell` as admin

1. clean cachec npm clean cache --force
2. delete insides of %AppData%/npm-cache/
3. delete %temp%
4. Delete the npm module which is causing the error. For me it was iconv. So deleted iconv and iconv-lite
5. When I built again, I got failure reason as a virus inside app-builder. I ran windows defender on node-module and removed that virus. Then, build again.
6. This time I was successful.

For me the sexier solution is to construct a dynamic associative array & use it

// A dirty array sent by user
$dirtyArray = ['Cecile', 'Gilles', 'Andre', 'Claude'];

// we construct an associative array like this
// [ ':name_0' => 'Cecile', ... , ':name_3' => 'Claude' ]
$params = array_combine(
    array_map(
        // construct param name according to array index
        function ($v) {return ":name_{$v}";},
        // get values of users
        array_keys($dirtyArray)
    ),
    $dirtyArray
);

// construct the query like `.. WHERE name IN ( :name_1, .. , :name_3 )`
$query = "SELECT * FROM user WHERE name IN( " . implode(",", array_keys($params)) . " )";
// here we go
$stmt  = $db->prepare($query);
$stmt->execute($params);

Found an answer myself, this blog helped: http://thingsyoudidntknowaboutjenkins.tumblr.com/post/23596855946/git-plugin-part-3

Basically need to execute:

git checkout master

before modifying any files

then

git commit -am "Updated version number"

after modified files

and then use post build action of Git Publisher with an option of Merge Results which will push changes to github on successful build.

As others have said,

new String[0]

will indeed create an empty array. However, there's one nice thing about arrays - their size can't change, so you can always use the same empty array reference. So in your code, you can use:

private static final String[] EMPTY_ARRAY = new String[0];

and then just return EMPTY_ARRAY each time you need it - there's no need to create a new object each time.

Here's the simplest solution with a clear selector:

function select_option(i) {
  return $('span#span_id select option[value="' + i + '"]').html();
}

If you are using a reverse proxy such as nginx in between, you could define a custom token, such as X-API-Token.

In nginx you would rewrite it for the upstream proxy (your rest api) to be just auth:

proxy_set_header Authorization $http_x_api_token;

... while nginx can use the original Authorization header to check HTTP AUth.

It would be neater to create a folder named "c:\programs writable\" and put you app below that one. That way a jungle of low c-folders can be avoided.

The underlying trade-off is security versus ease-of-use. If you know what you are doing you want to be god on you own pc. If you must maintain healthy systems for your local anarchistic society, you may want to add some security.

I solved this by copying the branch data (with the errors) to my apple laptop local git folder.

Somehow in the terminal and when running: git status, tells me more specific data where the error occurs. If you look under the errors, hopefully you see a list of folders with error. In my case GIT showed the folder which was responsible for the error. Deleting that folder and commiting the branche, I succeeded. git status was working again the other devices updating by git pull; everything working again on every machine.

Hopefully this will work for you also.

Here's a a couple of useful link that I found when I started with JNI

http://en.wikipedia.org/wiki/Java_Native_Interface
http://download.oracle.com/javase/1.5.0/docs/guide/jni/spec/functions.html

concerning your problem you can use this

JNIEXPORT void JNICALL Java_ClassName_MethodName(JNIEnv *env, jobject obj, jstring javaString)   
{
   const char *nativeString = env->GetStringUTFChars(javaString, 0);

   // use your string

   env->ReleaseStringUTFChars(javaString, nativeString);
}

Using not a to test whether a is None assumes that the other possible values of a have a truth value of True. However, most NumPy arrays don't have a truth value at all, and not cannot be applied to them.

If you want to test whether an object is None, the most general, reliable way is to literally use an is check against None:

if a is None:
    ...
else:
    ...

This doesn't depend on objects having a truth value, so it works with NumPy arrays.

Note that the test has to be is, not ==. is is an object identity test. == is whatever the arguments say it is, and NumPy arrays say it's a broadcasted elementwise equality comparison, producing a boolean array:

>>> a = numpy.arange(5)
>>> a == None
array([False, False, False, False, False])
>>> if a == None:
...     pass
...
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: The truth value of an array with more than one element is ambiguous.
 Use a.any() or a.all()

On the other side of things, if you want to test whether an object is a NumPy array, you can test its type:

# Careful - the type is np.ndarray, not np.array. np.array is a factory function.
if type(a) is np.ndarray:
    ...
else:
    ...

You can also use isinstance, which will also return True for subclasses of that type (if that is what you want). Considering how terrible and incompatible np.matrix is, you may not actually want this:

# Again, ndarray, not array, because array is a factory function.
if isinstance(a, np.ndarray):
    ...
else:
    ...    

Foto indicator use this:

 tabLayout.setSelectedTabIndicatorColor(ContextCompat.getColor(this, R.color.colorWhite));//put your color

In my case, I got a similar error and it was happening because I had run mongod with the root user and that had created a log file only accessible by the root. I could fix this by changing the ownership from root to the user you normally run mongod from. The log file was in /var/lib/mongodb/journal/

With the web.xml configured they way you have in the question, in particular:

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/*</url-pattern>
</servlet-mapping>

ALL requests being made to your web app will be directed to the DispatcherServlet. This includes requests like /tasklist/, /tasklist/some-thing.html, /tasklist/WEB-INF/views/index.jsp.

Because of this, when your controller returns a view that points to a .jsp, instead of allowing your server container to service the request, the DispatcherServlet jumps in and starts looking for a controller that can service this request, it doesn't find any and hence the 404.

The simplest way to solve is to have your servlet url mapping as follows:

<servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Notice the missing *. This tells the container that any request that does not have a path info in it (urls without a .xxx at the end), should be sent to the DispatcherServlet. With this configuration, when a xxx.jsp request is received, the DispatcherServlet is not consulted, and your servlet container's default servlet will service the request and present the jsp as expected.

Hope this helps, I realize your earlier comments state that the problem has been resolved, but the solution CAN NOT be just adding method=RequestMethod.GET to the RequestMethod.

All what you have to do is to revert the commit.

git revert {commit_id}'

Then push it

git push origin -f

You can use the command wget to download from command line. Specifically, you could use

wget http://download.oracle.com/otn-pub/java/jdk/7u10-b18/jdk-7u10-linux-x64.tar.gz

However because Oracle requires you to accept a license agreement this may not work (and I am currently unable to test it).

using braces surrounding the numbers will treat as addition instead of concat.

divID = "question-" + (i+1)

this does not refresh your component I solved the problem by using Vux create a module for vuex "page"

export const state = {
    currentScrollY: 0,
};

export const getters = {
    currentScrollY: s => s.currentScrollY
};

export const actions = {
    setCurrentScrollY ({ commit }, y) {
        commit('setCurrentScrollY', {y});
    },
};

export const mutations = {
    setCurrentScrollY (s, {y}) {
       s.currentScrollY = y;
    },
};

export default {
    state,
    getters,
    actions,
    mutations,
};

in App.vue :

created() {
    window.addEventListener("scroll", this.handleScroll);
  },
  destroyed() {
    window.removeEventListener("scroll", this.handleScroll);
  },
  methods: {
    handleScroll () {
      this.$store.dispatch("page/setCurrentScrollY", window.scrollY);
      
    }
  },

in your component :

  computed: {
    currentScrollY() {
      return this.$store.getters["page/currentScrollY"];
    }
  },

  watch: {
    currentScrollY(val) {
      if (val > 100) {
        this.isVisibleStickyMenu = true;
      } else {
        this.isVisibleStickyMenu = false;
      }
    }
  },

and it works great.

Another approach that's a little more semantic is to have a UL defined as your total 6 image width, each LI defined as float left and width defined - so that when LI #7 hits, it runs into the boundry of the UL, and is pushed down to the new row. You'll still have an open float that you'll want to clear after the /UL - but that can be done on the next element of the page, or as a clear div. Here's sort of the idea, you may have to mess with actual values, but this should give you the idea. The code is a little cleaner.

 <style type="text/css"> 
ul#imageSet { width: 600px; margin: 0; padding:0; }
ul#imageSet li { float: left; width: 100px;  height: 188px; margin: 0; padding:0; position: relative; list-style-type: none; }
.cornerimage { position: absolute; bottom: 0; right: 0; } 
h3.nextelement { clear: both; }
</style>

<h3 class="nextelement">Next Element in Doc</h3>

Your server is imposing some resource limit that your site is hitting. This is usually RAM, CPU, or INODES.

Ask your server administrator what the limits are and what it is you are hitting to solve.

See Creating and modifying HTML at what used to be called the Web Standards Curriculum.

Use the createElement, createTextNode and appendChild methods.

Depending on the version of JavaScript you have available, you can use indexOf:

Returns the first index at which a given element can be found in the array, or -1 if it is not present.

Or some:

Tests whether some element in the array passes the test implemented by the provided function.

But, if you're doing this sort of existence check a lot you'd be better of using an Object to store your strings (or perhaps an object as well as the Array depending on what you're doing with your data).

The basename command has two different invocations; in one, you specify just the path, in which case it gives you the last component, while in the other you also give a suffix that it will remove. So, you can simplify your example code by using the second invocation of basename. Also, be careful to correctly quote things:

fbname=$(basename "$1" .txt)
echo "$fbname"

This will get you to an answer for your simple case, but can you expand on how you'll know which columns will need to be compared (B and C in this case) and what the initial range (A1:D5 in this case) will be? Then I can try to provide a more complete answer.

Sub setCondFormat()
    Range("B3").Select
    With Range("B3:H63")
        .FormatConditions.Add Type:=xlExpression, Formula1:= _
          "=IF($D3="""",FALSE,IF($F3>=$E3,TRUE,FALSE))"
        With .FormatConditions(.FormatConditions.Count)
            .SetFirstPriority
            With .Interior
                .PatternColorIndex = xlAutomatic
                .Color = 5287936
                .TintAndShade = 0
            End With
        End With
    End With
End Sub

There is probably a faster way:

df %>%
  group_by(id) %>%
  arrange(stopSequence) %>%
  filter(row_number()==1 | row_number()==n())

Since Python 2.6.X you might want to use:

"my {0} string: {1}".format("cool", "Hello there!")

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

Here's my go-to method for a yes/no answer.

It's case-insensitive also.

This just checks for the errors given by the input and sets the choice variable to whatever you require so it can be used below in the code.

@echo off
choice /M "[Opt 1]  Do you want to continue [Yes/No]"
if errorlevel 255 (
  echo Error
  ) else if errorlevel 2 (
  set "YourChoice=will not"
  ) else if errorlevel 1 (
  set "YourChoice=will"
  ) else if errorlevel 0 (
  goto :EOF
  )
  echo %YourChoice%
  pause

In Javascript method names are camel case, so it's replace, not Replace:

$scope.newString = oldString.replace("stackover","NO");

Note that contrary to how the .NET Replace method works, the Javascript replace method replaces only the first occurrence if you are using a string as first parameter. If you want to replace all occurrences you need to use a regular expression so that you can specify the global (g) flag:

$scope.newString = oldString.replace(/stackover/g,"NO");

See this example.

Try string manipulation:

var txt = "I expect five hundred dollars ($500). and new brackets ($600)";
var newTxt = txt.split('(');
for (var i = 1; i < newTxt.length; i++) {
    console.log(newTxt[i].split(')')[0]);
}

or regex (which is somewhat slow compare to the above)

var txt = "I expect five hundred dollars ($500). and new brackets ($600)";
var regExp = /\(([^)]+)\)/g;
var matches = txt.match(regExp);
for (var i = 0; i < matches.length; i++) {
    var str = matches[i];
    console.log(str.substring(1, str.length - 1));
}

Simply make a div to be the direct child of body (with the class name bg for example), encompassing all other elements in the body, and add this to the CSS file:

.bg {
    background-image: url('_images/home.jpg');//Put your appropriate image URL here
    background-size: 100% 100%; //You need to put 100% twice here to stretch width and height
}

Refer to this link: https://www.w3schools.com/css/css_rwd_images.asp Scroll down to the part that says:

2. If the background-size property is set to "100% 100%", the background image will stretch to cover the entire content area

There it shows the 'img_flowers.jpg' stretching to the size of the screen or browser regardless of how you resize it.

I am doing this way:

<div class="card-logo">
    <img height="100%" width="100%" src="http://someimage.jpg">
</div>

and CSS:

.card-logo {
    width: 20%;
}

I prefer this way, as if I need to upscale - I can use 150% as well

It's called a verbatim string literal in C#, and it's just a matter of putting @ before the literal. Not only does this allow multiple lines, but it also turns off escaping. So for example you can do:

string query = @"SELECT foo, bar
FROM table
WHERE name = 'a\b'";

This includes the line breaks (using whatever line break your source has them as) into the string, however. For SQL, that's not only harmless but probably improves the readability anywhere you see the string - but in other places it may not be required, in which case you'd either need to not use a multi-line verbatim string literal to start with, or remove them from the resulting string.

The only bit of escaping is that if you want a double quote, you have to add an extra double quote symbol:

string quote = @"Jon said, ""This will work,"" - and it did!";

Jasmine doesn't have that functionality, but you might be able to hack something together using Object.defineProperty.

You could refactor your code to use a getter function, then spy on the getter.

spyOn(myObj, 'getValueA').andReturn(1);
expect(myObj.getValueA()).toBe(1);

The model (@Model) only exists while the page is being constructed. Once the page is rendered in the browser, all that exists is HTML, JavaScript and CSS.

What you will want to do is put the PostID in a hidden field. As the PostID value is fixed, there actually is no need for JavaScript. A simple @HtmlHiddenFor will suffice.

However, you will want to change your foreach loop to a for loop. The final solution will look something like this:

for (int i = 0 ; i < Model.Post; i++)
{
    <br/>
    <b>Posted by :</b> @Model.Post[i].Username <br/>
    <span>@Model.Post[i].Content</span> <br/>
    if(Model.loginuser == Model.username)
    {
        @Html.HiddenFor(model => model.Post[i].PostID)
        @Html.TextAreaFor(model => model.addcomment.Content)
        <button type="submit">Add Comment</button>
    }
}

Another simple solution is to create a filter:

app.filter('trusted', ['$sce', function ($sce) {
    return function(url) {
        return $sce.trustAsResourceUrl(url);
    };
}]);

Then specify the filter in ng-src:

<video controls poster="img/poster.png">
       <source ng-src="{{object.src | trusted}}" type="video/mp4"/>
</video>

Using top: 40px and bottom: 40px (assuming your footer is also 40px) with no defined height, you can get this to work.

.header {
    width: 100%;
    height: 40px;
    position: absolute;
    top: 0;
    background-color:red;
}
.mainBody {
    width: 100%;
    top: 40px;
    bottom: 40px;
    position: absolute;
    background-color: gray;
}
.footer {
    width: 100%;
    height: 40px;
    position: absolute;
    bottom: 0;
    background-color: blue;
}

JSFiddle

I had the same problem and a better way to solve it without using !important was defining the following in my CSS:

table th.text-center, table td.text-center { 
    text-align: center;
}

That way the specifity of the text-center class works correctly in tables.

For future reference, you can get help for any command by using the /? switch, which should explain what switches do what.

According to the set /? screen, the format for set /p is SET /P variable=[promptString] which would indicate that the p in /p is "prompt." It just prints in your example because <nul passes in a nul character which immediately ends the prompt so it just acts like it's printing. It's still technically prompting for input, it's just immediately receiving it.

/L in for /L generates a List of numbers.

From ping /?:

Usage: ping [-t] [-a] [-n count] [-l size] [-f] [-i TTL] [-v TOS]
            [-r count] [-s count] [[-j host-list] | [-k host-list]]
            [-w timeout] [-R] [-S srcaddr] [-4] [-6] target_name

Options:
    -t             Ping the specified host until stopped.
                   To see statistics and continue - type Control-Break;
                   To stop - type Control-C.
    -a             Resolve addresses to hostnames.
    -n count       Number of echo requests to send.
    -l size        Send buffer size.
    -f             Set Don't Fragment flag in packet (IPv4-only).
    -i TTL         Time To Live.
    -v TOS         Type Of Service (IPv4-only. This setting has been deprecated
                   and has no effect on the type of service field in the IP Header).
    -r count       Record route for count hops (IPv4-only).
    -s count       Timestamp for count hops (IPv4-only).
    -j host-list   Loose source route along host-list (IPv4-only).
    -k host-list   Strict source route along host-list (IPv4-only).
    -w timeout     Timeout in milliseconds to wait for each reply.
    -R             Use routing header to test reverse route also (IPv6-only).
    -S srcaddr     Source address to use.
    -4             Force using IPv4.
    -6             Force using IPv6.

Better to use arc4random_uniform. However, this isn't available below iOS 4.3. Luckily iOS will bind this symbol at runtime, not at compile time (so don't use the #if preprocessor directive to check if it's available).

The best way to determine if arc4random_uniform is available is to do something like this:

#include <stdlib.h>

int r = 0;
if (arc4random_uniform != NULL)
    r = arc4random_uniform (74);
else
    r = (arc4random() % 74);

I have recently started working on a project using Vue JS, JSON Schema. I am trying to access nested JSON Objects from a JSON Schema file in the Vue app. I tried the below code and now I can load different JSON objects inside different Vue template tags. In the script tag add the below code

import  {JsonObject1name, JsonObject2name} from 'your Json file path';

Now you can access JsonObject1,2 names in data section of export default part as below:

data: () => ({ 
  
  schema: JsonObject1name,
  schema1: JsonObject2name,   
  
  model: {} 
}),

Now you can load the schema, schema1 data inside Vue template according to your requirement. See below code for example :

      <SchemaForm id="unique name representing your Json object1" class="form"  v-model="model" :schema="schema" :components="components">
      </SchemaForm>  

      <SchemaForm id="unique name representing your Json object2" class="form" v-model="model" :schema="schema1" :components="components">
      </SchemaForm>

SchemaForm is the local variable name for @formSchema/native library. I have implemented the data of different JSON objects through forms in different CSS tabs.

I hope this answer helps someone. I can help if there are any questions.

I know the post is old, but I believe this is yet another way to do it. I just implemented on my code. Works perfectly both on page load and on page resize:

var videoHeight;
var videoWidth;
var iframeHeight;
var iframeWidth;

function resizeIframe(){
    videoHeight = $('.video-container').height();//iframe parent div's height
    videoWidth = $('.video-container').width();//iframe parent div's width

    iframeHeight = $('.youtubeFrames').height(videoHeight);//iframe's height
    iframeWidth = $('.youtubeFrames').width(videoWidth);//iframe's width
}
resizeIframe();


$(window).on('resize', function(){
    resizeIframe();
});

well this worked for me:

pip install mysqlclient

this is for python 3.x

Try using this :

function checkValue(){_x000D_
  var value = $('#doc_title').val();_x000D_
  if (value.length > 0) {_x000D_
        $('#doc_title').val("");_x000D_
        $('#doc_title').focus();  // To focus the input _x000D_
    }_x000D_
    else{_x000D_
    //do something_x000D_
    }_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<body>_x000D_
<input type="text" id="doc_title" value="Sample text"/>_x000D_
<button onclick="checkValue()">Check Value</button>_x000D_
</body>

Put this code wherever you want to insert a new line:

bufferedWriter.newLine();

Time.utc(2010, 05, 17)

can test it:

describe('TableItem Components', () => {
    let open_url = ""
    const { open } = window;
    beforeAll(() => {
        delete window.open;
        window.open = (url) => { open_url = url };
    });
    afterAll(() => {
        window.open = open;
    });
    test('string type', async () => {
        wrapper.vm.openNewTab('http://example.com')
        expect(open_url).toBe('http://example.com')
    })
})

fetch vs pull

fetch will download any changes from the remote* branch, updating your repository data, but leaving your local* branch unchanged.

pull will perform a fetch and additionally merge the changes into your local branch.

What's the difference? pull updates you local branch with changes from the pulled branch. A fetch does not advance your local branch.

merge vs rebase

Given the following history:

          C---D---E local
         /
    A---B---F---G remote

merge joins two development histories together. It does this by replaying the changes that occurred on your local branch after it diverged on top of the remote branch, and record the result in a new commit. This operation preserves the ancestry of each commit.

The effect of a merge will be:

          C---D---E local

rebase will take commits that exist in your local branch and re-apply them on top of the remote branch. This operation re-writes the ancestors of your local commits.

The effect of a rebase will be:

                  C'--D'--E' local
                 /
    A---B---F---G remote

What's the difference? A merge does not change the ancestry of commits. A rebase rewrites the ancestry of your local commits.

* This explanation assumes that the current branch is a local branch, and that the branch specified as the argument to fetch, pull, merge, or rebase is a remote branch. This is the usual case. pull, for example, will download any changes from the specified branch, update your repository and merge the changes into the current branch.

In my case I happened to be using lombok and apparently there are conflicts with the get and set

If you are running postgresql on mac os, try these:

1. Edit the pg_hba.conf file

2. sudo vi /Library/PostgreSQL/9.2/data/pg_hba.conf

3. Change the "md5" method for all users to "trust" near the bottom of the file

4. Find the name of the service

5. ls /Library/LaunchDaemons

6. Look for postgresql

7. Stop the postgresql service

8. sudo launchctl stop com.edb.launchd.postgresql-9.2

9. Start the postgresql service

10. sudo launchctl start com.edb.launchd.postgresql-9.2

11. Start psql session as postgres

12. psql -U postgres

13. (shouldn't ask for password because of 'trust' setting)

14. Reset password in psql session by typing

15. ALTER USER postgres with password 'secure-new-password';

16. \q

17. enter

18. Edit the pg_hba.conf file

19. Switch it back to 'md5'

20. Restart services again

Enabling SQL Server Service Broker requires a database lock. Stop the SQL Server Agent and then execute the following:

USE master ;
GO

ALTER DATABASE [MyDatabase] SET ENABLE_BROKER ;
GO

Change [MyDatabase] with the name of your database in question and then start SQL Server Agent.

If you want to see all the databases that have Service Broker enabled or disabled, then query sys.databases, for instance:

SELECT
    name, database_id, is_broker_enabled
FROM sys.databases

Closing a SpringApplication basically means closing the underlying ApplicationContext. The SpringApplication#run(String...) method gives you that ApplicationContext as a ConfigurableApplicationContext. You can then close() it yourself.

For example,

@SpringBootApplication
public class Example {
    public static void main(String[] args) {
        ConfigurableApplicationContext ctx = SpringApplication.run(Example.class, args);
        // ...determine it's time to shut down...
        ctx.close();
    }
}

Alternatively, you can use the static SpringApplication.exit(ApplicationContext, ExitCodeGenerator...) helper method to do it for you. For example,

@SpringBootApplication
public class Example {
    public static void main(String[] args) {
        ConfigurableApplicationContext ctx = SpringApplication.run(Example.class, args);
        // ...determine it's time to stop...
        int exitCode = SpringApplication.exit(ctx, new ExitCodeGenerator() {
            @Override
            public int getExitCode() {
                // no errors
                return 0;
            }
        });

        // or shortened to
        // int exitCode = SpringApplication.exit(ctx, () -> 0);

        System.exit(exitCode);
    }
}

A Simple Approach will be to use a normal link and add Bootstrap modal effect to it. Just make use of my Code, hopefully you will get it run.

 <div class="container">
        <div class="row">
            <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="addContact" aria-hidden="true">
                <div class="modal-dialog">
                    <div class="modal-content">
                        <div class="modal-header">

                                    <div id="speechTab" class="tab-pane fade in"><partial name="CreateSpeechTag"></div>
                                </div>

                            </div>
                        </div>
                        <div class="modal-footer">

If you have a self-signed certificate generated by makecert.exe on a Windows machine, you will get two files: cert.pvk and cert.cer. These can be converted to a pfx using pvk2pfx

pvk2pfx is found in the same location as makecert (e.g. C:\Program Files (x86)\Windows Kits\10\bin\x86 or similar)

pvk2pfx -pvk cert.pvk -spc cert.cer -pfx cert.pfx

The latest set of guidance is as follows: (from https://docs.microsoft.com/en-us/azure/azure-functions/functions-dotnet-class-library#environment-variables)

Use:

System.Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);

From the docs:

public static class EnvironmentVariablesExample
{
    [FunctionName("GetEnvironmentVariables")]
    public static void Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer, ILogger log)
    {
        log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
        log.LogInformation(GetEnvironmentVariable("AzureWebJobsStorage"));
        log.LogInformation(GetEnvironmentVariable("WEBSITE_SITE_NAME"));
    }

    public static string GetEnvironmentVariable(string name)
    {
        return name + ": " +
            System.Environment.GetEnvironmentVariable(name, EnvironmentVariableTarget.Process);
    }
}

App settings can be read from environment variables both when developing locally and when running in Azure. When developing locally, app settings come from the Values collection in the local.settings.json file. In both environments, local and Azure, GetEnvironmentVariable("<app setting name>") retrieves the value of the named app setting. For instance, when you're running locally, "My Site Name" would be returned if your local.settings.json file contains { "Values": { "WEBSITE_SITE_NAME": "My Site Name" } }.

The System.Configuration.ConfigurationManager.AppSettings property is an alternative API for getting app setting values, but we recommend that you use GetEnvironmentVariable as shown here.

See Stirling's Approximation:

ln(n!) = n*ln(n) - n + O(ln(n))

where the last 2 terms are less significant than the first one.

** Update**: 11/19/2019

Microsoft has released a new version of the control 150.1400.0 in their Nuget library. My short testing shows that it works again in the forms designer where 150.1357.0 and 150.1358.0 did not. This includes being able to resize and modify the ReportViewer Tasks on the control itself.

** Update**: 8/18/2019

Removing the latest version and rolling back to 150.900.148.0 seems to work on multiple computers I'm using with VS2017 and VS2019.

You can roll back to 150.900.148 in the Nuget solution package manager. It works similarly to the previous versions. Use the drop down box to select the older version.

It may be easier to manually delete references to post 150.900 versions of ReportViewer and readd them than it is to fix them.

Remember to restart Visual Studio after changing the toolbox entry.

Update: 8/7/2019

A newer version of the ReportViewer control has been released, probably coinciding with Visual Studio 2019. I was working with V150.1358.0.

Following the directions in this answer gets the control in the designer's toolbox. But once dropped on the form it doesn't display. The control shows up below the form as a non-visual component.

This is working as designed according to Microsoft SQL BI support. This is the group responsible for the control.

While you still cannot interact with the control directly, these additional steps give a workaround so the control can be sized on the form. While now visible, the designer treats the control as if it didn't exist.

I've created a feedback request at the suggestion of Microsoft SQL BI support. Please consider voting on it to get Microsoft's attention.

Microsoft Azure Feedback page - Restore Designtime features of the WinForms ReportViewer Control

Additional steps:

• After adding the reportviewer to the WinForm
• Add a Panel Control to the WinForm.

• In the form's form.designer.cs file, add the Reportviewer control to the panel.

    // 
    // panel1
    // 
    this.panel1.Controls.Add(this.reportViewer1);
  

• Return to the form's designer, you should see the reportViewer on the panel

• In the Properties panel select the ReportViewer in the controls list dropdown
• Set the reportViewer's Dock property to Fill

Now you can position the reportViewer by actually interacting with the panel.

Update: Microsoft released a document on April 18, 2017 describing how to configure and use the reporting tool in Visual Studio 2017.

Visual Studio 2017 does not have the ReportViewer tool installed by default in the ToolBox. Installing the extension Microsoft Rdlc Report Designer for Visual Studio and then adding that to the ToolBox results in a non-visual component that appears below the form.

Microsoft Support had told me this is a bug, but as of April 21, 2017 it is "working as designed".

The following steps need to be followed for each project that requires ReportViewer.

• If you have ReportViewer in the Toolbox, remove it. Highlight, right-click and delete.
  • You will have to have a project with a form open to do this.

Edited 8/7/2019 - It looks like the current version of the RDLC Report Designer extension no longer interferes. You need this to actually edit the reports.

• If you have the Microsoft Rdlc Report Designer for Visual Studio extension installed, uninstall it.

• Close your solution and restart Visual Studio. This is a crucial step, errors will occur if VS is not restarted when switching between solutions.

• Open your solution.
• Open the NuGet Package Manager Console (Tools/NuGet Package Manager/Package Manager Console)

• At the PM> prompt enter this command, case matters.

  Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms

  You should see text describing the installation of the package.

Now we can temporarily add the ReportViewer tool to the tool box.

• Right-click in the toolbox and use Choose Items...

• We need to browse to the proper DLL that is located in the solutions Packages folder, so hit the browse button.

• In our example we can paste in the packages folder as shown in the text of Package Manager Console.

  C:\Users\jdoe\Documents\Projects\_Test\ReportViewerTest\WindowsFormsApp1\packages

• Then double click on the folder named Microsoft.ReportingServices.ReportViewerControl.Winforms.140.340.80

  The version number will probably change in the future.

• Then double-click on lib and again on net40.

• Finally, double click on the file Microsoft.ReportViewer.WinForms.dll

  You should see ReportViewer checked in the dialog. Scroll to the right and you will see the version 14.0.0.0 associated to it.

• Click OK.

ReportViewer is now located in the ToolBox.

• Drag the tool to the desired form(s).

• Once completed, delete the ReportViewer tool from the tool box. You can't use it with another project.

• You may save the project and are good to go.

Remember to restart Visual Studio any time you need to open a project with ReportViewer so that the DLL is loaded from the correct location. If you try and open a solution with a form with ReportViewer without restarting you will see errors indicating that the “The variable 'reportViewer1' is either undeclared or was never assigned.“.

If you add a new project to the same solution you need to create the project, save the solution, restart Visual Studio and then you should be able to add the ReportViewer to the form. I have seen it not work the first time and show up as a non-visual component.

When that happens, removing the component from the form, deleting the Microsoft.ReportViewer.* references from the project, saving and restarting usually works.

WhatsApp Inc. does not provide an open API but a reverse-engineered library is made available on GitHub by the team Venomous on the GitHub. This however according to my knowledge is made possible in PHP. You can check the link here: https://github.com/venomous0x/WhatsAPI

Hope this helps

I have written a node module that provides a wrapper around setInterval using moment durations providing a declarative interface:

npm install every-moment

var every = require('every-moment');

var timer = every(5, 'seconds', function() {
    console.log(this.duration);
});

every(2, 'weeks', function() {
    console.log(this.duration);
    timer.stop();
    this.set(1, 'week');
    this.start();
});
