I'd re-iterate Donny V. answer and Josh's

"The only reason I wouldn't use the async version is if I were trying to support an older version of .NET that does not already have built in async support."

(and upvote if I had the reputation.)

I can't remember the last time if ever, I was grateful of the fact HttpWebRequest threw exceptions for status codes >= 400. To get around these issues you need to catch the exceptions immediately, and map them to some non-exception response mechanisms in your code...boring, tedious and error prone in itself. Whether it be communicating with a database, or implementing a bespoke web proxy, its 'nearly' always desirable that the Http driver just tell your application code what was returned, and leave it up to you to decide how to behave.

Hence HttpClient is preferable.

Actually, if you try to use function "children" it will not be succesfull because it's possible to the table has a first child like 'th'. So you have to use function 'find' instead.

Wrong way:

var $row = $(this).closest('table').children('tr:first');

Correct way:

 var $row = $(this).closest('table').find('tr:first');

• Use float: right to.. float the second column to the.. right.
• Use overflow: hidden to clear the floats so that the background color I just put in will be visible.

Live Demo

#wrapper{
    background:#000;
    overflow: hidden
}
#c1 {
   float:left;
   background:red;
}
#c2 {
    background:green;
    float: right
}

And if you need to style your form elements according to it's state (modified/not modified) dynamically or to test whether some values has actually changed, you can use the following module, developed by myself: https://github.com/betsol/angular-input-modified

It adds additional properties and methods to the form and it's child elements. With it, you can test whether some element contains new data or even test if entire form has new unsaved data.

You can setup the following watch: $scope.$watch('myForm.modified', handler) and your handler will be called if some form elements actually contains new data or if it reversed to initial state.

Also, you can use modified property of individual form elements to actually reduce amount of data sent to a server via AJAX call. There is no need to send unchanged data.

As a bonus, you can revert your form to initial state via call to form's reset() method.

You can find the module's demo here: http://plnkr.co/edit/g2MDXv81OOBuGo6ORvdt?p=preview

In Ubuntu 18.04 the QtCreator examples and API docs missing, This is my way to solve this problem, should apply to almost every Ubuntu release.

For QtCreator and Examples and API Docs:

sudo apt install `apt-cache search 5-examples | grep qt | grep example | awk '{print $1 }' | xargs `

sudo apt install `apt-cache search 5-doc | grep "Qt 5 " | awk '{print $1}' | xargs`

sudo apt-get install build-essential qtcreator qt5-default

If something is also missing, then:

sudo apt install `apt-cache search qt | grep 5- | grep ^qt | awk '{print $1}' | xargs `

Hope to be helpful.

You can use names directly in the read_csv

names : array-like, default None List of column names to use. If file contains no header row, then you should explicitly pass header=None

Cov = pd.read_csv("path/to/file.txt", 
                  sep='\t', 
                  names=["Sequence", "Start", "End", "Coverage"])

Thanks Jason Rogers's answer first.

In Android && cpp should be this:

const char *nativeString = env->GetStringUTFChars(javaString, nullptr);

// use your string

env->ReleaseStringUTFChars(javaString, nativeString);

Can fix this errors:

1.error: base operand of '->' has non-pointer type 'JNIEnv {aka _JNIEnv}'

2.error: no matching function for call to '_JNIEnv::GetStringUTFChars(JNIEnv*&, _jstring*&, bool)'

3.error: no matching function for call to '_JNIEnv::ReleaseStringUTFChars(JNIEnv*&, _jstring*&, char const*&)'

4.add "env->DeleteLocalRef(nativeString);" at end.

Change [ to [[, and ] to ]].

Don't look too far.

If you develop with ASP.NET MVC, you simply have the user as a property of the Controller class. So in case you get lost in some models looking for the current user, try to step back and to get the relevant information in the controller.

In the controller, just use:

using Microsoft.AspNet.Identity;

  ...

  var userId = User.Identity.GetUserId();
  ...

with userId as a string.

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

If you want they to be paragraph, then use it.

<p><label for="id1">label1:</label> <input type="text" id="id1"/></p>
<p><label for="id2">label2:</label> <input type="text" id="id2"/></p>

Both <label> and <input> are paragraph and flow content so you can insert as paragraph elements and as block elements.

Necroing this question because I recently ran into the problem myself, when trying to add a related property to an existing entity. I just ended up making a nice extension method:

    public static MvcHtmlString HiddenFor<TModel, TProperty>(this HtmlHelper<TModel> htmlHelper, Expression<Func<TModel, TProperty>> expression, TProperty value)
    {
        string expressionText = ExpressionHelper.GetExpressionText(expression);
        string propertyName = htmlHelper.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(expressionText);

        return htmlHelper.Hidden(propertyName, value);
    }

Use like so:

@Html.HiddenFor(m => m.RELATED_ID, Related.Id)

Note that this has a similar signature to the built-in HiddenFor, but uses generic typing, so if Value is of type System.Object, you'll actually be invoking the one built into the framework. Not sure why you'd be editing a property of type System.Object in your views though...

I'm usually using

var dictionary:[String:String] = [:]
dictionary.removeAll()

You must check this: Docblock Comment standards

Let's use

mysqli_connect

instead of

mysql_connect

because mysql_connect isn't supported in PHP 7.

I am running Sierra, and was working on this for a while (trying all recommended solutions). I became confounded so eventually tried restarting my computer! It worked

my conclusion is that sometimes a hard reset is necessary

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

Your code seems fine except the result is an NSArray, not an NSDictionary, here is an example:

The first two lines just creates a data object with the JSON, the same as you would get reading it from the net.

NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"Aaa\"}, {\"id\": \"2\", \"name\":\"Bbb\"}]";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];

NSError *e;
NSMutableArray *jsonList = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&e];
NSLog(@"jsonList: %@", jsonList);

NSLog contents (a list of dictionaries):

jsonList: (
           {
               id = 1;
               name = Aaa;
           },
           {
               id = 2;
               name = Bbb;
           }
           )

There could be different reasons why it doesn't work for you: perhaps you need to qualify the name with std::, or perhaps you do not have C++11 support.

This works, provided you have C++11 support:

#include <string>

int main()
{
  std::string s = std::to_string(42);
}

To enable C++11 support with g++ or clang, you need to pass the option -std=c++0x. You can also use -std=c++11 on the newer versions of those compilers.

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

try this:

$('html, body').animate({scrollTop:$('#xxx').position().top}, 'slow');
$('#xxx').focus();

If you are facing issue with angular/cli then use the following commands:
npm uninstall -g angular-cli to uninstall the angular/cli.
npm cache clean to clean your npm cache from app data folder under your username.
use npm cache verify to verify your cache whether it is corrupted or not.
use npm cache verify --force to clean your entire cache from your system.

Note:
You can also delete by the following the paths
C:\Users\"Your_syste_User_name"\AppData\Roaming\npm and
C:\Users\"Your_syste_User_name"\AppData\Roaming\npm-cache
Then use the following command to install latest angular/cli version globally in your system.
npm install -g @angular/cli@latest
To get more information visit github angular-cli update.

You can use pd.DataFrame constructor, giving a numpy array (data) and a list of the names of the columns (columns). To have everything in one DataFrame, you can concatenate the features and the target into one numpy array with np.c_[...] (note the square brackets and not parenthesis). Also, you can have some trouble if you don't convert the feature names (iris['feature_names']) to a list before concatenation:

import numpy as np
import pandas as pd
from sklearn.datasets import load_iris

iris = load_iris()

df = pd.DataFrame(data= np.c_[iris['data'], iris['target']],
                     columns= list(iris['feature_names']) + ['target'])

Continuing this answer, There is another difference that if you want your method to return different values for example when it is first time called, second time called etc then you can pass values so for example...

PowerMockito.doReturn(false, false, true).when(SomeClass.class, "SomeMethod", Matchers.any(SomeClass.class));

So it will return false when the method is called in same test case and then it will return false again and lastly true.

Git’s executable is actually located in: C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin\git.exe

Now that we have located the executable all we have to do is add it to our PATH:

• Right-Click on My Computer
• Click Advanced System Settings
• Click Environment Variables
• Then under System Variables look for the path variable and click edit
• Add the path to git’s bin and cmd at the end of the string like this:

;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\bin;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd

For completeness, in Numpy there are four maximum related functions. They fall into two different categories:

• np.amax/np.max, np.nanmax: for single array order statistics
• and np.maximum, np.fmax: for element-wise comparison of two arrays

I. For single array order statistics

NaNs propagator np.amax/np.max and its NaN ignorant counterpart np.nanmax.

• np.max is just an alias of np.amax, so they are considered as one function.

  >>> np.max.__name__
  'amax'
  >>> np.max is np.amax
  True
  

• np.max propagates NaNs while np.nanmax ignores NaNs.

  >>> np.max([np.nan, 3.14, -1])
  nan
  >>> np.nanmax([np.nan, 3.14, -1])
  3.14
  

II. For element-wise comparison of two arrays

NaNs propagator np.maximum and its NaNs ignorant counterpart np.fmax.

• Both functions require two arrays as the first two positional args to compare with.

  # x1 and x2 must be the same shape or can be broadcast
  np.maximum(x1, x2, /, ...);
  np.fmax(x1, x2, /, ...)
  

• np.maximum propagates NaNs while np.fmax ignores NaNs.

  >>> np.maximum([np.nan, 3.14, 0], [np.NINF, np.nan, 2.72])
  array([ nan,  nan, 2.72])
  >>> np.fmax([np.nan, 3.14, 0], [np.NINF, np.nan, 2.72])
  array([-inf, 3.14, 2.72])
  

• The element-wise functions are np.ufunc(Universal Function), which means they have some special properties that normal Numpy function don't have.

  >>> type(np.maximum)
  <class 'numpy.ufunc'>
  >>> type(np.fmax)
  <class 'numpy.ufunc'>
  >>> #---------------#
  >>> type(np.max)
  <class 'function'>
  >>> type(np.nanmax)
  <class 'function'>
  

And finally, the same rules apply to the four minimum related functions:

• np.amin/np.min, np.nanmin;
• and np.minimum, np.fmin.

You could detect position of the mouse pointer and then move the web page (with body position relative) so they hover over what you want them to click.

For an example you can paste this code on the current page in your browser console (and refresh afterwards)

var upvote_position = $('#answer-12878316').position();
$('body').mousemove(function (event) {
    $(this).css({
        position: 'relative',
        left: (event.pageX - upvote_position.left - 22) + 'px',
        top: (event.pageY - upvote_position.top - 35) + 'px'
    });        
});

In Cocoa, to compare dates, use one of isEqualToDate, compare, laterDate, and earlierDate methods on NSDate objects, instantiated with the dates you need.

Window is the main JavaScript object root, aka the global object in a browser, also can be treated as the root of the document object model. You can access it as window

window.screen or just screen is a small information object about physical screen dimensions.

window.document or just document is the main object of the potentially visible (or better yet: rendered) document object model/DOM.

Since window is the global object you can reference any properties of it with just the property name - so you do not have to write down window. - it will be figured out by the runtime.

It depends on how you store the parsed CSV, but generally you want the del operator.

If you have an array of dicts:

input = [ {'day':01, 'month':04, 'year':2001, ...}, ... ]
for E in input: del E['year']

If you have an array of arrays:

input = [ [01, 04, 2001, ...],
          [...],
          ...
        ]
for E in input: del E[2]

jQuery is a DOM manipulation library.

AngularJS is an MV* framework.

In fact, AngularJS is one of the few JavaScript MV* frameworks (many JavaScript MVC tools still fall under the category library).

Being a framework, it hosts your code and takes ownership of decisions about what to call and when!

AngularJS itself includes a jQuery-lite edition within it. So for some basic DOM selection/manipulation, you really don't have to include the jQuery library (it saves many bytes to run on the network.)

AngularJS has the concept of "Directives" for DOM manipulation and designing reusable UI components, so you should use it whenever you feel the need of doing DOM manipulation related stuff (directives are only place where you should write jQuery code while using AngularJS).

AngularJS involves some learning curve (more than jQuery :-).

-->For any developer coming from jQuery background, my first advice would be to "learn JavaScript as a first class language before jumping onto a rich framework like AngularJS!" I learned the above fact the hard way.

Good luck.

A solution very easy to do it

Note : it's only for an asynchrone call, because service isn't initialized on config execution.

You can use run() method. Example :

1. Your service is called "MyService"
2. You want to use it for an asynchrone execution on a provider "MyProvider"

Your code :

(function () { //To isolate code TO NEVER HAVE A GLOBAL VARIABLE!

    //Store your service into an internal variable
    //It's an internal variable because you have wrapped this code with a (function () { --- })();
    var theServiceToInject = null;

    //Declare your application
    var myApp = angular.module("MyApplication", []);

    //Set configuration
    myApp.config(['MyProvider', function (MyProvider) {
        MyProvider.callMyMethod(function () {
            theServiceToInject.methodOnService();
        });
    }]);

    //When application is initialized inject your service
    myApp.run(['MyService', function (MyService) {
        theServiceToInject = MyService;
    }]);
});

In your example, the div's height is static and the image's height is static. Give the image a margin-top value of ( div_height - image_height ) / 2

If the image is 50px, then

img {
    margin-top: 25px;
}

As the README describes, you can reuse the Docker daemon from Minikube with eval $(minikube docker-env).

So to use an image without uploading it, you can follow these steps:

1. Set the environment variables with eval $(minikube docker-env)
2. Build the image with the Docker daemon of Minikube (eg docker build -t my-image .)
3. Set the image in the pod spec like the build tag (eg my-image)
4. Set the imagePullPolicy to Never, otherwise Kubernetes will try to download the image.

Important note: You have to run eval $(minikube docker-env) on each terminal you want to use, since it only sets the environment variables for the current shell session.

Not really an answer to the specific question, but if there are others, like me, who are getting this error in fastAPI and end up here:

It is probably because your route response has a value that can't be JSON serialised by jsonable_encoder. For me it was WKBElement: https://github.com/tiangolo/fastapi/issues/2366

Like in the issue, I ended up just removing the value from the output.

You can't refer to a property of an object before you have initialized that object; use an external variable.

var key1 = "it";
var obj = {
  key1 : key1,
  key2 : key1 + " works!"
};

Also, this is not a "JSON object"; it is a Javascript object. JSON is a method of representing an object with a string (which happens to be valid Javascript code).

A submodule is its own repo/work-area, with its own .git directory.

So, first commit/push your submodule's changes:

$ cd path/to/submodule
$ git add <stuff>
$ git commit -m "comment"
$ git push

Then, update your main project to track the updated version of the submodule:

$ cd /main/project
$ git add path/to/submodule
$ git commit -m "updated my submodule"
$ git push

There are working combinations of OS, JDK and Eclipse bitness. In my case, I was using a 64-bit JDK with a 32-bit Eclipse on a 64-bit OS. After downgrading the JDK to 32-bit, Eclipse started working.

Kindly use one of the following combinations.

32-bit OS, 32-bit JDK, 32-bit Eclipse (32-bit only)

64-bit OS, 32-bit JDK, 32-bit Eclipse

64-bit OS, 64-bit JDK, 64-bit Eclipse (64-bit only)

Here is an example

Query query = em.createQuery("from Student");
             java.util.List list = query.getResultList();
             for (int i = 0; i < list.size(); i++) 
             {

                 student = (Student) list.get(i);
                 System.out.println(student.id  + "  " + student.age + " " + student.name + " " + student.prenom);

             }

Depending on what browsers you're targeting, you could go for the object-fit property to solve this:

object-fit: cover;

or maybe fill is what you're looking for. Still under consideration for IE.

If you do not use DockerFile, you can simply add permission as command line argument of the bash:

docker run -t <image>  /bin/bash -c "chmod +x /usr/src/app/docker-entrypoint.sh; /usr/src/app/docker-entrypoint.sh"

Here is a working exemple :

printf("-%s-", (char[2]){'A', 0});

This will display -A-

To change a cell value using a column name, one can use

iris$Sepal.Length[3]=999

In addition to @fyrye's very helpful answer this is an okayish workaround for the mentioned bug (this one), that DatePeriod substracts one hour when entering summertime, but doesn't add one hour when leaving summertime (and thus Europe/Berlin's March has its correct 743 hours but October has 744 instead of 745 hours):

Counting the hours of a month (or any timespan), considering DST-transitions in both directions

function getMonthHours(string $year, string $month, \DateTimeZone $timezone): int
{
    // or whatever start and end \DateTimeInterface objects you like
    $start = new \DateTimeImmutable($year . '-' . $month . '-01 00:00:00', $timezone);
    $end = new \DateTimeImmutable((new \DateTimeImmutable($year . '-' . $month . '-01 23:59:59', $timezone))->format('Y-m-t H:i:s'), $timezone);
    
    // count the hours just utilizing \DatePeriod, \DateInterval and iterator_count, hell yeah!
    $hours = iterator_count(new \DatePeriod($start, new \DateInterval('PT1H'), $end));
    
    // find transitions and check, if there is one that leads to a positive offset
    // that isn't added by \DatePeriod
    // this is the workaround for https://bugs.php.net/bug.php?id=75685
    $transitions = $timezone->getTransitions((int)$start->format('U'), (int)$end->format('U'));
    if (2 === count($transitions) && $transitions[0]['offset'] - $transitions[1]['offset'] > 0) {
        $hours += (round(($transitions[0]['offset'] - $transitions[1]['offset'])/3600));
    }
    
    return $hours;
}

$myTimezoneWithDST = new \DateTimeZone('Europe/Berlin');
var_dump(getMonthHours('2020', '01', $myTimezoneWithDST)); // 744
var_dump(getMonthHours('2020', '03', $myTimezoneWithDST)); // 743
var_dump(getMonthHours('2020', '10', $myTimezoneWithDST)); // 745, finally!

$myTimezoneWithoutDST = new \DateTimeZone('UTC');
var_dump(getMonthHours('2020', '01', $myTimezoneWithoutDST)); // 744
var_dump(getMonthHours('2020', '03', $myTimezoneWithoutDST)); // 744
var_dump(getMonthHours('2020', '10', $myTimezoneWithoutDST)); // 744

P.S. If you check a (longer) timespan, which leads to more than those two transitions, my workaround won't touch the counted hours to reduce the potential of funny side effects. In such cases, a more complicated solution must be implemented. One could iterate over all found transitions and compare the current with the last and check if it is one with DST true->false.

Something like this:

STARTUPINFO info={sizeof(info)};
PROCESS_INFORMATION processInfo;
if (CreateProcess(path, cmd, NULL, NULL, TRUE, 0, NULL, NULL, &info, &processInfo))
{
    WaitForSingleObject(processInfo.hProcess, INFINITE);
    CloseHandle(processInfo.hProcess);
    CloseHandle(processInfo.hThread);
}

I have some code in my game that displays live score. It is in a function for quick access.

def texts(score):
   font=pygame.font.Font(None,30)
   scoretext=font.render("Score:"+str(score), 1,(255,255,255))
   screen.blit(scoretext, (500, 457))

and I call it using this in my while loop:

texts(score)

My solution was to use excel (2010).

In a new worksheet, select a cell, then:

Data -> From Other Sources -> From SQL Server 

put in the server name, select table, etc,

When you get to the "Import Data" dialog,
click on Properties in the "Connection Properties" dialog,
select the "Definition" tab.

And there Excel nicely displays the Connection String for copying
(or even Export Connection File...)

The ast.literal_eval function comes close, but it will expect the string to be properly quoted first.

Of course Python's interpretation of backslash escapes depends on how the string is quoted ("" vs r"" vs u"", triple quotes, etc) so you may want to wrap the user input in suitable quotes and pass to literal_eval. Wrapping it in quotes will also prevent literal_eval from returning a number, tuple, dictionary, etc.

Things still might get tricky if the user types unquoted quotes of the type you intend to wrap around the string.

One of the most elegant solutions was here Get characters after last / in url

by DisgruntledGoat

$id = substr($url, strrpos($url, '/') + 1);

strrpos gets the position of the last occurrence of the slash; substr returns everything after that position.

Adding 'playsinline' works for me on Iphone and Ipa if you don't mind your video being muted.

<video muted playsinline>
  <source src="..." type="video/mp4">
</video>

If you don't want your video being muted, but still want autoplay, maybe try to remove muted attribute with js: How to unmute html5 video with a muted prop

We had a similar issue. We were trying to GET from:

[RoutePrefix("api/car")]
public class CarController: ApiController{

    [HTTPGet]
    [Route("")]
    public virtual async Task<ActionResult> GetAll(){

    }

}

So we would .GET("/api/car") and this would throw a 405 error.

The CarController.cs file was in the directory /api/car so when we were requesting this api endpoint, IIS would send back an error because it looked like we were trying to access a virtual directory that we were not allowed to.

Option 1: change / rename the directory the controller is in
Option 2: change the route prefix to something that doesn't match the virtual directory.

I presume you meant false instead of 'false'

Also, [disabled] is expecting a Boolean. You should avoid returning a null.

Use sum() in place of count()

Try below:

SELECT
    ccc_news . * , 
    SUM(if(ccc_news_comments.id = 'approved', 1, 0)) AS comments
FROM
    ccc_news
    LEFT JOIN
        ccc_news_comments
    ON
        ccc_news_comments.news_id = ccc_news.news_id
WHERE
    `ccc_news`.`category` = 'news_layer2'
    AND `ccc_news`.`status` = 'Active'
GROUP BY
    ccc_news.news_id
ORDER BY
    ccc_news.set_order ASC
LIMIT 20 

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

Running the following experiment the pythonic way:

[s + mystring for s in mylist]

seems to be ~35% faster than the obvious use of a for loop like this:

i = 0
for s in mylist:
    mylist[i] = s+mystring
    i = i + 1

Experiment

import random
import string
import time

mystring = '/test/'

l = []
ref_list = []

for i in xrange( 10**6 ):
    ref_list.append( ''.join(random.choice(string.ascii_lowercase) for i in range(10)) )

for numOfElements in [5, 10, 15 ]:

    l = ref_list*numOfElements
    print 'Number of elements:', len(l)

    l1 = list( l )
    l2 = list( l )

    # Method A
    start_time = time.time()
    l2 = [s + mystring for s in l2]
    stop_time = time.time()
    dt1 = stop_time - start_time
    del l2
    #~ print "Method A: %s seconds" % (dt1)

    # Method B
    start_time = time.time()
    i = 0
    for s in l1:
        l1[i] = s+mystring
        i = i + 1
    stop_time = time.time()
    dt0 = stop_time - start_time
    del l1
    del l
    #~ print "Method B: %s seconds" % (dt0)

    print 'Method A is %.1f%% faster than Method B' % ((1 - dt1/dt0)*100)

Results

Number of elements: 5000000
Method A is 38.4% faster than Method B
Number of elements: 10000000
Method A is 33.8% faster than Method B
Number of elements: 15000000
Method A is 35.5% faster than Method B

I had installed anaconda via the system installer on OS X in the past, which created a ~/.conda/environments.txt owned by root. Conda could not modify this file, hence the error.

To fix this issue, I changed the ownership of that directory and file to my username:

sudo chown -R $USER ~/.conda

This should do it, let me know if you have trouble with it:

Sub foo()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, copy what you want from x:
x.Sheets("name of copying sheet").Range("A1").Copy

'Now, paste to y worksheet:
y.Sheets("sheetname").Range("A1").PasteSpecial

'Close x:
x.Close

End Sub

Alternatively, you could just:

Sub foo2()
Dim x As Workbook
Dim y As Workbook

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Now, transfer values from x to y:
y.Sheets("sheetname").Range("A1").Value = x.Sheets("name of copying sheet").Range("A1") 

'Close x:
x.Close

End Sub

To extend this to the entire sheet:

With x.Sheets("name of copying sheet").UsedRange
    'Now, paste to y worksheet:
    y.Sheets("sheet name").Range("A1").Resize( _
        .Rows.Count, .Columns.Count) = .Value
End With

And yet another way, store the value as a variable and write the variable to the destination:

Sub foo3()
Dim x As Workbook
Dim y As Workbook
Dim vals as Variant

'## Open both workbooks first:
Set x = Workbooks.Open(" path to copying book ")
Set y = Workbooks.Open(" path to destination book ")

'Store the value in a variable:
vals = x.Sheets("name of sheet").Range("A1").Value

'Use the variable to assign a value to the other file/sheet:
y.Sheets("sheetname").Range("A1").Value = vals 

'Close x:
x.Close

End Sub

The last method above is usually the fastest for most applications, but do note that for very large datasets (100k rows) it's observed that the Clipboard actually outperforms the array dump:

Copy/PasteSpecial vs Range.Value = Range.Value

That said, there are other considerations than just speed, and it may be the case that the performance hit on a large dataset is worth the tradeoff, to avoid interacting with the Clipboard.

Just to share my idea...

I created a custom class to inherit the Label class. I added a private variable assigned as a Tooltip class and a public property, TooltipText. Then, gave it a MouseEnter delegate method. This is an easy way to work with multiple Label controls and not have to worry about assigning your Tooltip control for each Label control.

    public partial class ucLabel : Label
    {
        private ToolTip _tt = new ToolTip();

        public string TooltipText { get; set; }

        public ucLabel() : base() {
            _tt.AutoPopDelay = 1500;
            _tt.InitialDelay = 400;
//            _tt.IsBalloon = true;
            _tt.UseAnimation = true;
            _tt.UseFading = true;
            _tt.Active = true;
            this.MouseEnter += new EventHandler(this.ucLabel_MouseEnter);
        }

        private void ucLabel_MouseEnter(object sender, EventArgs ea)
        {
            if (!string.IsNullOrEmpty(this.TooltipText))
            {
                _tt.SetToolTip(this, this.TooltipText);
                _tt.Show(this.TooltipText, this.Parent);
            }
        }
    }

In the form or user control's InitializeComponent method (the Designer code), reassign your Label control to the custom class:

this.lblMyLabel = new ucLabel();

Also, change the private variable reference in the Designer code:

private ucLabel lblMyLabel;

Linus is spot on in the approach, but a few properties are off. It looks like 'AgencyContractId' is your Primary Key, which is unrelated to the output you want to give the user. I think this is what you want (assuming you change your ViewModel to match the data you say you want in your view).

var agencyContracts = _agencyContractsRepository.AgencyContracts
    .GroupBy(ac => new
                   {
                       ac.AgencyID,
                       ac.VendorID,
                       ac.RegionID
                   })
    .Select(ac => new AgencyContractViewModel
                   {
                       AgencyId = ac.Key.AgencyID,
                       VendorId = ac.Key.VendorID,
                       RegionId = ac.Key.RegionID,
                       Total = ac.Sum(acs => acs.Amount) + ac.Sum(acs => acs.Fee)
                   });

I am posting this because this took me hours to find so i hope it may help someone.

I had a problem that the shadow/elevation was not showing though i created a simple activity and placed the toolbar as follows:

 <androidx.appcompat.widget.Toolbar
        android:id="@+id/mt_toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:layout_collapseMode="pin"
        android:background="@color/colorPrimaryDark"
        android:elevation="12dp"/>

It turns out that in the manifest setting android:hardwareAccelerated="false" was causing it! once i removed it, the shadow appeared

You should in fact URI-encode the "invalid" characters. Since the string actually contains the complete URL, it's hard to properly URI-encode it. You don't know which slashes / should be taken into account and which not. You cannot predict that on a raw String beforehand. The problem really needs to be solved at a higher level. Where does that String come from? Is it hardcoded? Then just change it yourself accordingly. Does it come in as user input? Validate it and show error, let the user solve itself.

At any way, if you can ensure that it are only the spaces in URLs which makes it invalid, then you can also just do a string-by-string replace with %20:

URI uri = new URI(string.replace(" ", "%20"));

Or if you can ensure that it's only the part after the last slash which needs to be URI-encoded, then you can also just do so with help of android.net.Uri utility class:

int pos = string.lastIndexOf('/') + 1;
URI uri = new URI(string.substring(0, pos) + Uri.encode(string.substring(pos)));

Do note that URLEncoder is insuitable for the task as it's designed to encode query string parameter names/values as per application/x-www-form-urlencoded rules (as used in HTML forms). See also Java URL encoding of query string parameters.

You should use the excellent OpenCSV for reading and writing CSV files. To adapt your example to use the library it would look like this:

public class ParseCSV {
  public static void main(String[] args) {
    try {
      //csv file containing data
      String strFile = "C:/Users/rsaluja/CMS_Evaluation/Drupal_12_08_27.csv";
      CSVReader reader = new CSVReader(new FileReader(strFile));
      String [] nextLine;
      int lineNumber = 0;
      while ((nextLine = reader.readNext()) != null) {
        lineNumber++;
        System.out.println("Line # " + lineNumber);

        // nextLine[] is an array of values from the line
        System.out.println(nextLine[4] + "etc...");
      }
    }
  }
}

By using below, solved the problem

android:scrollbarThumbVertical="@null"

You can simply check the creation date of Windows Folder (right click on it and check properties) :)

Of course. The whole idea of abstract classes is that they can contain some behaviour or data which you require all sub-classes to contain. Think of the simple example of WheeledVehicle - it should have a numWheels member variable. You want all sub classes to have this variable. Remember that abstract classes are a very useful feature when developing APIs, as they can ensure that people who extend your API won't break it.

If you are converting price (in string) to decimal price then....

from decimal import Decimal

price = "14000,45"
price_in_decimal = Decimal(price.replace(',','.'))

No need for the replace if your strings already use dots as a decimal separator

With JRE 8 on XP there is another way - to use MSI to deploy package.

• Install JRE 8 x86 on a PC with supported OS
• Copy c:\Users[USER]\AppData\LocalLow\Sun\Java\jre1.8.0\jre1.8.0.msi and Data1.cab to XP PC and run jre1.8.0.msi
  

or (silent way, usable in batch file etc..)

for %%I in ("*.msi") do if exist "%%I" msiexec.exe /i %%I /qn EULA=0 SKIPLICENSE=1 PROG=0 ENDDIALOG=0

You can also convert by creating a dictionary of elements and then directly converting to a data frame:

import xml.etree.ElementTree as ET
import pandas as pd

# Contents of test.xml
# <?xml version="1.0" encoding="utf-8"?> <tags>   <row Id="1" TagName="bayesian" Count="4699" ExcerptPostId="20258" WikiPostId="20257" />   <row Id="2" TagName="prior" Count="598" ExcerptPostId="62158" WikiPostId="62157" />   <row Id="3" TagName="elicitation" Count="10" />   <row Id="5" TagName="open-source" Count="16" /> </tags>

root = ET.parse('test.xml').getroot()

tags = {"tags":[]}
for elem in root:
    tag = {}
    tag["Id"] = elem.attrib['Id']
    tag["TagName"] = elem.attrib['TagName']
    tag["Count"] = elem.attrib['Count']
    tags["tags"]. append(tag)

df_users = pd.DataFrame(tags["tags"])
df_users.head()

If you're using jQuery UI dialog, you could just style the modal to appear with the position fixed in the window so it doesn't pop-up out of view, negating the need to scroll. Otherwise,

var scrollTop = function() {
    window.scrollTo(0, 0);
};

should do the trick.

Please use an inner query inside of the in-clause:

select col1, col2, col3... from table1
 where id in (select id from table2 where conditions...)

If you're using jquery anyhow, check out the $.doTimeout plugin. This thing is a huge improvement over setTimeout, including letting you keep track of your time-outs with a single string id that you specify and that doesn't change every time you set it, and implement easy canceling, polling loops & debouncing, and more. One of my most-used jquery plugins.

Unfortunately, it doesn't support pause/resume out of the box. For this, you would need to wrap or extend $.doTimeout, presumably similarly to the accepted answer.

Are you sure that you have specified the correct paths?

You need to be in the right directory, i.e.

C:\Program Files\MongoDB\bin

and the path you are installing into needs to be the correct one

i.e.

mongod --dbpath 
C:\Users\Name\Documents\myWebsites\nodetest1

A folder named "data" must also exist in your project folder.

I got the same error and this worked for me.

@Corey - It just simply strips out all invalid characters. However, your comment made me think of the answer.

The problem was that many of the fields in my database are nullable. When using SqlBulkCopy, an empty string is not inserted as a null value. So in the case of my fields that are not varchar (bit, int, decimal, datetime, etc) it was trying to insert an empty string, which obviously is not valid for that data type.

The solution was to modify my loop where I validate the values to this (repeated for each datatype that is not string)

//--- convert decimal values
foreach (DataColumn DecCol in DecimalColumns)
{
     if(string.IsNullOrEmpty(dr[DecCol].ToString()))
          dr[DecCol] = null; //--- this had to be set to null, not empty
     else
          dr[DecCol] = Helpers.CleanDecimal(dr[DecCol].ToString());
}

After making the adjustments above, everything inserts without issues.

if you post a file from mobile device or other

    byte[] fileData = null;
    using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
    {
        fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
    }

console.log(Math.floor(100000 + Math.random() * 900000));

Will always create a number of 6 digits and it ensures the first digit will never be 0. The code in your question will create a number of less than 6 digits.

Use the microtime function. The documentation includes example code.

Had this error too, the cause was simple, but not obvious: incorrect password. Not sure why I didn't get just "Login failed" from freshly installed SQL 2016 server.

The documentation for Gerrit, in particular the "Push changes" section, explains that you push to the "magical refs/for/'branch' ref using any Git client tool".

The following image is taken from the Intro to Gerrit. When you push to Gerrit, you do git push gerrit HEAD:refs/for/<BRANCH>. This pushes your changes to the staging area (in the diagram, "Pending Changes"). Gerrit doesn't actually have a branch called <BRANCH>; it lies to the git client.

Internally, Gerrit has its own implementation for the Git and SSH stacks. This allows it to provide the "magical" refs/for/<BRANCH> refs.

When a push request is received to create a ref in one of these namespaces Gerrit performs its own logic to update the database, and then lies to the client about the result of the operation. A successful result causes the client to believe that Gerrit has created the ref, but in reality Gerrit hasn’t created the ref at all. [Link - Gerrit, "Gritty Details"].

After a successful patch (i.e, the patch has been pushed to Gerrit, [putting it into the "Pending Changes" staging area], reviewed, and the review has passed), Gerrit pushes the change from the "Pending Changes" into the "Authoritative Repository", calculating which branch to push it into based on the magic it did when you pushed to refs/for/<BRANCH>. This way, successfully reviewed patches can be pulled directly from the correct branches of the Authoritative Repository.

A simple way is to use tail(-n) to remove the first n rows

df=df.tail(-3)

Thanks for the help everyone, rejecting the promise in .catch() solved my issue:

export function fetchVehicle(id) {
    return dispatch => {
        return dispatch({
            type: 'FETCH_VEHICLE',
            payload: fetch(`http://swapi.co/api/vehicles/${id}/`)
                .then(status)
                .then(res => res.json())    
                .catch(error => {
                    return Promise.reject()
                })
            });
    };
}


function status(res) {
    if (!res.ok) {
        throw new Error(res.statusText);
    }
    return res;
}

Here is my simplistic log4j2.xml that prints to console and writes to a daily rolling file:

// java

            <AppenderRef ref="rollingFile" />
        </Root>
    </Loggers>
</Configuration>

TimeBasedTriggeringPolicy

interval (integer) - How often a rollover should occur based on the most specific time unit in the date pattern. For example, with a date pattern with hours as the most specific item and and increment of 4 rollovers would occur every 4 hours. The default value is 1.

modulate (boolean) - Indicates whether the interval should be adjusted to cause the next rollover to occur on the interval boundary. For example, if the item is hours, the current hour is 3 am and the interval is 4 then the first rollover will occur at 4 am and then next ones will occur at 8 am, noon, 4pm, etc.

A new log file will be created daily with previous day automatically renamed to:

cucumber_yyyy-MM-dd.log

In a Maven project, you would put the log4j2.xml in src/main/resources or src/test/resources.

if (obj === undefined)
{
    // Create obj
}

If you are doing extensive javascript programming you should get in the habit of using === and !== when you want to make a type specific check.

Also if you are going to be doing a fair amount of javascript, I suggest running code through JSLint http://www.jslint.com it might seem a bit draconian at first, but most of the things JSLint warns you about will eventually come back to bite you.

In my case, I had to load the Map on my Wordpress website and the problem was that the Google's api script was loading before the initMap(). Therefore, I solved the problem with a delay:

<script>
function initMap() {
     // Your Javascript Codes for the map
     ...
}

<?php
// Delay for 5 seconds
sleep(5);
?>

</script>
<script async defer src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEYWY&callback=initMap"></script>

Within your component, you can define an array of number (ES6) as described below:

export class SampleComponent {
  constructor() {
    this.numbers = Array(5).fill(0).map((x,i)=>i);
  }
}

See this link for the array creation: Tersest way to create an array of integers from 1..20 in JavaScript.

You can then iterate over this array with ngFor:

@View({
  template: `
    <ul>
      <li *ngFor="let number of numbers">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Or shortly:

@View({
  template: `
    <ul>
      <li *ngFor="let number of [0,1,2,3,4]">{{number}}</li>
    </ul>
  `
})
export class SampleComponent {
  (...)
}

Hope it helps you, Thierry

Edit: Fixed the fill statement and template syntax.

       var request = require('request');
        request({
            url: "http://localhost:8001/xyz",
            json: true,
            headers: {
                "content-type": "application/json",
            },
            body: JSON.stringify(requestData)
        }, function(error, response, body) {
            console.log(response);
        });

I looked at the designer code from one of my projects and noticed it used this notation

myButton.Image = global::MyProjectName.Properties.Resources.max;

where max is the name of the resource I uploaded into the project.

You can use as below

e.preventDefault() 

If this method is called, the default action of the event will not be triggered.

Also if I may suggest read this: .prop() vs .attr()

I hope it will help you,

code example:

$('a').click(function(event){
    event.preventDefault();
    //do what you want
  } 

This problem might occur if you define 2 different schema's with same Collection name

merge is used to bring two (or more) branches together.

a little example:

# on branch A:
# create new branch B
$ git checkout -b B
# hack hack
$ git commit -am "commit on branch B"

# create new branch C from A
$ git checkout -b C A
# hack hack
$ git commit -am "commit on branch C"

# go back to branch A
$ git checkout A
# hack hack
$ git commit -am "commit on branch A"

so now there are three separate branches (namely A B and C) with different heads

to get the changes from B and C back to A, checkout A (already done in this example) and then use the merge command:

# create an octopus merge
$ git merge B C

your history will then look something like this:

…-o-o-x-------A
      |\     /|
      | B---/ |
       \     /
        C---/

if you want to merge across repository/computer borders, have a look at git pull command, e.g. from the pc with branch A (this example will create two new commits):

# pull branch B
$ git pull ssh://host/… B
# pull branch C
$ git pull ssh://host/… C

chart.js supports this by defaul check the link. chartjs

you can set the label in the options attribute.

options object looks like this.

options = {
            scales: {
                yAxes: [
                    {
                        id: 'y-axis-1',
                        display: true,
                        position: 'left',
                        ticks: {
                            callback: function(value, index, values) {
                                return value + "%";
                            }
                        },
                        scaleLabel:{
                            display: true,
                            labelString: 'Average Personal Income',
                            fontColor: "#546372"
                        }
                    }   
                ]
            }
        };

All of the following examples use

var str = "Hello, playground"

startIndex and endIndex

• startIndex is the index of the first character
• endIndex is the index after the last character.

Example

// character
str[str.startIndex] // H
str[str.endIndex]   // error: after last character

// range
let range = str.startIndex..<str.endIndex
str[range]  // "Hello, playground"

With Swift 4's one-sided ranges, the range can be simplified to one of the following forms.

let range = str.startIndex...
let range = ..<str.endIndex

I will use the full form in the follow examples for the sake of clarity, but for the sake of readability, you will probably want to use the one-sided ranges in your code.

after

As in: index(after: String.Index)

• after refers to the index of the character directly after the given index.

Examples

// character
let index = str.index(after: str.startIndex)
str[index]  // "e"

// range
let range = str.index(after: str.startIndex)..<str.endIndex
str[range]  // "ello, playground"

before

As in: index(before: String.Index)

• before refers to the index of the character directly before the given index.

Examples

// character
let index = str.index(before: str.endIndex)
str[index]  // d

// range
let range = str.startIndex..<str.index(before: str.endIndex)
str[range]  // Hello, playgroun

offsetBy

As in: index(String.Index, offsetBy: String.IndexDistance)

• The offsetBy value can be positive or negative and starts from the given index. Although it is of the type String.IndexDistance, you can give it an Int.

Examples

// character
let index = str.index(str.startIndex, offsetBy: 7)
str[index]  // p

// range
let start = str.index(str.startIndex, offsetBy: 7)
let end = str.index(str.endIndex, offsetBy: -6)
let range = start..<end
str[range]  // play

limitedBy

As in: index(String.Index, offsetBy: String.IndexDistance, limitedBy: String.Index)

• The limitedBy is useful for making sure that the offset does not cause the index to go out of bounds. It is a bounding index. Since it is possible for the offset to exceed the limit, this method returns an Optional. It returns nil if the index is out of bounds.

Example

// character
if let index = str.index(str.startIndex, offsetBy: 7, limitedBy: str.endIndex) {
    str[index]  // p
}

If the offset had been 77 instead of 7, then the if statement would have been skipped.

Why is String.Index needed?

It would be much easier to use an Int index for Strings. The reason that you have to create a new String.Index for every String is that Characters in Swift are not all the same length under the hood. A single Swift Character might be composed of one, two, or even more Unicode code points. Thus each unique String must calculate the indexes of its Characters.

It is possibly to hide this complexity behind an Int index extension, but I am reluctant to do so. It is good to be reminded of what is actually happening.

Every answer uses .next() or uses .beforeFirst() and then .next(). But why not this:

result.first();

So You just set the pointer to the first record and go from there. It's available since java 1.2 and I just wanted to mention this for anyone whose ResultSet exists of one specific record.

A saw a different post that also had diacritical marks, which is great

s.replace(/[^a-zA-Z0-9À-ž\s]/g, "")

Just a quick heads-up to anyone else who is losing their mind right now:

https://github.com/tmux/tmux/blob/310f0a960ca64fa3809545badc629c0c166c6cd2/CHANGES#L12

so that's just

 :setw -g mouse

There are various libraries that can resolve E for you using techniques similar to what the Robertson article discussed. Here's an implemenation of createContents that uses TypeTools to resolve the raw class represented by E:

E createContents() throws Exception {
  return TypeTools.resolveRawArgument(SomeContainer.class, getClass()).newInstance();
}

This assumes that getClass() resolves to a subclass of SomeContainer and will fail otherwise since the actual parameterized value of E will have been erased at runtime if it's not captured in a subclass.

If you use Firebug, you can use console.log to output an object and get a hyperlinked, explorable item in the console.

Clicking Properties, going to the Service tab and setting Start Mode to Automatic fixed the problem for me. Now the Start item in the context menu is active again.

Small change to the recursion to so you can for example find the child tab control of a tab control.

    public static DependencyObject FindInVisualTreeDown(DependencyObject obj, Type type)
    {
        if (obj != null)
        {
            for (int i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
            {
                DependencyObject child = VisualTreeHelper.GetChild(obj, i);

                if (child.GetType() == type)
                {
                    return child;
                }

                DependencyObject childReturn = FindInVisualTreeDown(child, type);
                if (childReturn != null)
                {
                    return childReturn;
                }
            }
        }

        return null;
    }

On your adapter's getItemViewType check if the adapter has 0 elements and return a different viewType if so.

Then on your onCreateViewHolder check if the viewType is the one you returned earlier and inflate a diferent view. In this case a layout file with that TextView

EDIT

If this is still not working then you might want to set the size of the view programatically like this:

Point size = new Point();
((WindowManager)itemView.getContext().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getSize(size);

And then when you inflate your view call:

inflatedView.getLayoutParams().height = size.y;
inflatedView.getLayoutParams().width = size.x;

<form class="form-poll" id="poll-1225962377536" action="/cs/Satellite" target="_blank">

The ID always starts with 'post-' then the numbers are dynamic.

Please check your id names, "poll" and "post" are very different.

As already answered, you can use querySelector:

var selectors = '[id^="poll-"]';
element = document.querySelector(selectors).id;

but querySelector will not find "poll" if you keep querying for "post": '[id^="post-"]'

(I found this answer from a video: http://www.youtube.com/watch?v=xmvRF7koJ5E)

1. Download msvcp71.dll and msvcr71.dll from the web.

2. Save them to your C:\Windows\System32 folder.

3. Save them to your C:\Windows\SysWOW64 folder as well (if you have a 64-bit operating system).

Now try running your code file in Python and it will load the graph in couple of seconds.

I looked for the answer to a similar question on this page, I wrote the answers to several similar questions that may help people who enter this page.

Class List

List < T > class represents the list of objects which can be accessed by index. It comes under the System.Collection.Generic namespace. List class can be used to create a collection of different types like integers, strings etc. List class also provides the methods to search, sort, and manipulate lists.

Class with property:

class TestClss
{
    public string id { set; get; }
    public string cell1 { set; get; }
    public string cell2 { set; get; }
}
var MyArray = new List<TestClss> {
    new TestClss() { id = "1", cell1 = "cell 1 row 1 Data", cell2 = "cell 2 row 1 Data" },
    new TestClss() { id = "2", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 2 Data" },
    new TestClss() { id = "3", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 3 Data" }
};
foreach (object Item in MyArray)
{
    Console.WriteLine("Row Start");
    foreach (PropertyInfo property in Item.GetType().GetProperties())
    {
        var Key = property.Name;
        var Value = property.GetValue(Item, null);
        Console.WriteLine("{0}={1}", Key, Value);
    }
}

OR, Class with field:

class TestClss
{
    public string id = "";
    public string cell1 = "";
    public string cell2 = "";
}
var MyArray = new List<TestClss> {
    new TestClss() { id = "1", cell1 = "cell 1 row 1 Data", cell2 = "cell 2 row 1 Data" },
    new TestClss() { id = "2", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 2 Data" },
    new TestClss() { id = "3", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 3 Data" }
};
foreach (object Item in MyArray)
{
    Console.WriteLine("Row Start");
    foreach (var fieldInfo in Item.GetType().GetFields())
    {
        var Key = fieldInfo.Name;
        var Value = fieldInfo.GetValue(Item);
    }

}

OR, List of objects (without same cells):

var MyArray = new List<object> {
    new { id = "1", cell1 = "cell 1 row 1 Data", cell2 = "cell 2 row 1 Data" },
    new { id = "2", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 2 Data" },
    new { id = "3", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 3 Data", anotherCell = "" }
};
foreach (object Item in MyArray)
{
    Console.WriteLine("Row Start");
    foreach (var props in Item.GetType().GetProperties())
    {
        var Key = props.Name;
        var Value = props.GetMethod.Invoke(Item, null).ToString();
        Console.WriteLine("{0}={1}", Key, Value);
    }
}

OR, List of objects (It must have the same cells):

var MyArray = new[] {
    new { id = "1", cell1 = "cell 1 row 1 Data", cell2 = "cell 2 row 1 Data" },
    new { id = "2", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 2 Data" },
    new { id = "3", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 3 Data" }
};
foreach (object Item in MyArray)
{
    Console.WriteLine("Row Start");
    foreach (var props in Item.GetType().GetProperties())
    {
        var Key = props.Name;
        var Value = props.GetMethod.Invoke(Item, null).ToString();
        Console.WriteLine("{0}={1}", Key, Value);
    }
}

OR, List of objects (with key):

var MyArray = new {
    row1 = new { id = "1", cell1 = "cell 1 row 1 Data", cell2 = "cell 2 row 1 Data" },
    row2 = new { id = "2", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 2 Data" },
    row3 = new { id = "3", cell1 = "cell 1 row 2 Data", cell2 = "cell 2 row 3 Data" }
};
// using System.ComponentModel;  for TypeDescriptor
foreach (PropertyDescriptor Item in TypeDescriptor.GetProperties(MyArray))
{
    string Rowkey = Item.Name;
    object RowValue = Item.GetValue(MyArray);
    Console.WriteLine("Row key is: {0}", Rowkey);
    foreach (var props in RowValue.GetType().GetProperties())
    {
        var Key = props.Name;
        var Value = props.GetMethod.Invoke(RowValue, null).ToString();
        Console.WriteLine("{0}={1}", Key, Value);
    }
}

OR, List of Dictionary

var MyArray = new List<Dictionary<string, string>>() {
    new Dictionary<string, string>() { { "id", "1" }, { "cell1", "cell 1 row 1 Data" }, { "cell2", "cell 2 row 1 Data" } },
    new Dictionary<string, string>() { { "id", "2" }, { "cell1", "cell 1 row 2 Data" }, { "cell2", "cell 2 row 2 Data" } },
    new Dictionary<string, string>() { { "id", "3" }, { "cell1", "cell 1 row 3 Data" }, { "cell2", "cell 2 row 3 Data" } }
};
foreach (Dictionary<string, string> Item in MyArray)
{
    Console.WriteLine("Row Start");
    foreach (KeyValuePair<string, string> props in Item)
    {
        var Key = props.Key;
        var Value = props.Value;
        Console.WriteLine("{0}={1}", Key, Value);
    }

Good luck..

this worked with me on linux

sdk install gradle 4.9

install sdk from here https://sdkman.io/

For programmatic usage, I use the following :

curlwithcode() {
    code=0
    # Run curl in a separate command, capturing output of -w "%{http_code}" into statuscode
    # and sending the content to a file with -o >(cat >/tmp/curl_body)
    statuscode=$(curl -w "%{http_code}" \
        -o >(cat >/tmp/curl_body) \
        "$@"
    ) || code="$?"

    body="$(cat /tmp/curl_body)"
    echo "statuscode : $statuscode"
    echo "exitcode : $code"
    echo "body : $body"
}

curlwithcode https://api.github.com/users/tj

It shows following output :

statuscode : 200
exitcode : 0
body : {
  "login": "tj",
  "id": 25254,
  ...
}

In addition to T.J. Crowders answer, I have added some more handlers - including the newer .on(...) handler to the snippet so you can see which events are being hidden and which ones not.

What I also found is that .live() is not only deprecated, but was deleted since jQuery 1.9.x. But the other ones, i.e.
.click, .delegate/.undelegate and .on/.off
are still there.

Also note there is more discussion about this topic here on Stackoverflow.

If you need to fix legacy code that is relying on .live, but you require to use a new version of jQuery (> 1.8.3), you can fix it with this snippet:

// fix if legacy code uses .live, but you want to user newer jQuery library
if (!$.fn.live) {
    // in this case .live does not exist, emulate .live by calling .on
    $.fn.live = function(events, handler) {
      $(this).on(events, null, {}, handler);
    };
}

The intention of the snippet below, which is an extension of T.J.'s script, is that you can try out by yourself instantly what happens if you bind multiple handlers - so please run the snippet and click on the texts below:

It does this by default, you just need to look into the project's /dist folder.

In MySQL, <> means Not Equal To, just like !=.

mysql> SELECT '.01' <> '0.01';
        -> 1
mysql> SELECT .01 <> '0.01';
        -> 0
mysql> SELECT 'zapp' <> 'zappp';
        -> 1

see the docs for more info

First you need to get the counts for each category, i.e. how many Bads and Goods and so on are there for each group (Food, Music, People). This would be done like so:

raw <- read.csv("http://pastebin.com/raw.php?i=L8cEKcxS",sep=",")
raw[,2]<-factor(raw[,2],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,3]<-factor(raw[,3],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)
raw[,4]<-factor(raw[,4],levels=c("Very Bad","Bad","Good","Very Good"),ordered=FALSE)

raw=raw[,c(2,3,4)] # getting rid of the "people" variable as I see no use for it

freq=table(col(raw), as.matrix(raw)) # get the counts of each factor level

Then you need to create a data frame out of it, melt it and plot it:

Names=c("Food","Music","People")     # create list of names
data=data.frame(cbind(freq),Names)   # combine them into a data frame
data=data[,c(5,3,1,2,4)]             # sort columns

# melt the data frame for plotting
data.m <- melt(data, id.vars='Names')

# plot everything
ggplot(data.m, aes(Names, value)) +   
  geom_bar(aes(fill = variable), position = "dodge", stat="identity")

Is this what you're after?

To clarify a little bit, in ggplot multiple grouping bar you had a data frame that looked like this:

> head(df)
  ID Type Annee X1PCE X2PCE X3PCE X4PCE X5PCE X6PCE
1  1    A  1980   450   338   154    36    13     9
2  2    A  2000   288   407   212    54    16    23
3  3    A  2020   196   434   246    68    19    36
4  4    B  1980   111   326   441    90    21    11
5  5    B  2000    63   298   443   133    42    21
6  6    B  2020    36   257   462   162    55    30

Since you have numerical values in columns 4-9, which would later be plotted on the y axis, this can be easily transformed with reshape and plotted.

For our current data set, we needed something similar, so we used freq=table(col(raw), as.matrix(raw)) to get this:

> data
   Names Very.Bad Bad Good Very.Good
1   Food        7   6    5         2
2  Music        5   5    7         3
3 People        6   3    7         4

Just imagine you have Very.Bad, Bad, Good and so on instead of X1PCE, X2PCE, X3PCE. See the similarity? But we needed to create such structure first. Hence the freq=table(col(raw), as.matrix(raw)).

The answer are as below for Window authentication

$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server=$SQLServer;Database=$SQLDBName;Integrated Security=True;"

If you want the #header to be the same width as your container, with 10px of padding, you can leave out its width declaration. That will cause it to implicitly take up its entire parent's width (since a div is by default a block level element).

Then, since you haven't defined a width on it, the 10px of padding will be properly applied inside the element, rather than adding to its width:

#container {
    position: relative;
    width: 80%;
}

#header {
    position: relative;
    height: 50px;
    padding: 10px;
}

You can see it in action here.

The key when using percentage widths and pixel padding/margins is not to define them on the same element (if you want to accurately control the size). Apply the percentage width to the parent and then the pixel padding/margin to a display: block child with no width set.

Update

Another option for dealing with this is to use the box-sizing CSS rule:

#container { 
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */

    /* Since this element now uses border-box sizing, the 10px of horizontal
       padding will be drawn inside the 80% width */
    width: 80%;
    padding: 0 10px;
}

Here's a post talking about how box-sizing works.

For those using homebrew you might fix this with:

$ brew link mysql

As this is specifically tagged for jQuery -

$("#myElement")[0].getBoundingClientRect();

or

$("#myElement").get(0).getBoundingClientRect();

(These are functionally identical, in some older browsers .get() was slightly faster)

Note that if you try to get the values via jQuery calls then it will not take into account any css transform values, which can give unexpected results...

Note 2: In jQuery 3.0 it has changed to using the proper getBoundingClientRect() calls for its own dimension calls (see the jQuery Core 3.0 Upgrade Guide) - which means that the other jQuery answers will finally always be correct - but only when using the new jQuery version - hence why it's called a breaking change...

Eclipse Collections

If you're using Eclipse Collections, you can use the anySatisfy() method. Either adapt your List in a ListAdapter or change your List into a ListIterable if possible.

ListIterable<MyObject> list = ...;

boolean result =
    list.anySatisfy(myObject -> myObject.getName().equals("John"));

If you'll do operations like this frequently, it's better to extract a method which answers whether the type has the attribute.

public class MyObject
{
    private final String name;

    public MyObject(String name)
    {
        this.name = name;
    }

    public boolean named(String name)
    {
        return Objects.equals(this.name, name);
    }
}

You can use the alternate form anySatisfyWith() together with a method reference.

boolean result = list.anySatisfyWith(MyObject::named, "John");

If you cannot change your List into a ListIterable, here's how you'd use ListAdapter.

boolean result = 
    ListAdapter.adapt(list).anySatisfyWith(MyObject::named, "John");

Note: I am a committer for Eclipse ollections.

The comparator should be only for the key, not for the whole entry. It sorts the entries based on the keys.

You should change it to something as follows

SortedMap<String, Double> myMap = 
    new TreeMap<String, Double>(new Comparator<String>()
    {
        public int compare(String o1, String o2)
        {
            return o1.compareTo(o2);
        } 
});

Update

You can do something as follows (create a list of entries in the map and sort the list base on value, but note this not going to sort the map itself) -

List<Map.Entry<String, Double>> entryList = new ArrayList<Map.Entry<String, Double>>(myMap.entrySet());
    Collections.sort(entryList, new Comparator<Map.Entry<String, Double>>() {
        @Override
        public int compare(Entry<String, Double> o1, Entry<String, Double> o2) {
            return o1.getValue().compareTo(o2.getValue());
        }
    });

Step 1: Goto https://projectlombok.org/download and click on 1.18.2

Step 2: Place your jar file in java installation path in my case it is C:\Program Files\Java\jdk-10.0.1\lib

step 3: Open your Eclipse IDE folder where you have in your PC.

Step 4: Add the place where I added then open your IDE it will open without any errors.

Assuming the type in your example, definitely prefer to initialize fields in the constructor. The exceptional cases are:

• Fields in static classes/methods
• Fields typed as static/final/et al

I always think of the field listing at the top of a class as the table of contents (what is contained herein, not how it is used), and the constructor as the introduction. Methods of course are chapters.

A much simpler way to do this is to use vCenter Converter Standalone Client and do a P2V but in this case a V2V. It is much faster than copying the entire VM files onto some storage somewhere and copy it onto your new vCenter. It takes a long time to copy or exporting it to an OVF template and then import it. You can set your vCenter Converter Standalone Client to V2V in one step and synchronize and then have it power up the VM on the new Vcenter and shut off on the old vCenter. Simple.

For me using this method I was able to move a VM from one vCenter to another vCenter in about 30 minutes as compared to copying or exporting which took over 2hrs. Your results may vary.

This process below, from another responder, would work even better if you can present that datastore to ESXi servers on the vCenter and then follow step 2. Eliminating having to copy all the VMs then follow rest of the process.

1. Copy all of the cloned VM's files from its directory, and place it on its destination datastore.
2. In the VI client connected to the destination vCenter, go to the Inventory->Datastores view.
3. Open the datastore browser for the datastore where you placed the VM's files.
4. Find the .vmx file that you copied over and right-click it.
5. Choose 'Register Virtual Machine', and follow whatever prompts ensue. (Depending on your version of vCenter, this may be 'Add to Inventory' or some other variant)

Just use append:

list1 = [1, 2, 3, 4, 5]
list2 = [123, 234, 456]
d = {'a': [], 'b': []}
d['a'].append(list1)
d['a'].append(list2)
print d['a']

For some configurations of ubuntu, the bind-address needs be changed in this file:

/etc/mysql/mysql.conf.d/mysqld.cnf 

JSONArray jsonChildArray = (JSONArray) jsonChildArray.get("LanguageLevels");
    JSONObject secObject = (JSONObject) jsonChildArray.get(1);

I think this should work, but i do not have the possibility to test it at the moment..

This is the simplest solution:

SELECT quote FROM quotes ORDER BY RAND() 

Although it is not the most efficient. This one is a better solution.

I discovered a strange behaviour, since in one of my apps, the soft keyboard was automatically showing on entering the activity (there is an editText.requestFocus() in onCreate).

On digging further, I discovered that this was because there is a ScrollView around the layout. If I remove the ScrollView, the behaviour is as described in the original problem statement: only on clicking the already focused editText does the soft keyboard show up.

If it doesn't work for you, try putting in a ScrollView -- it's harmless anyway.

Collection<Map<Item, Integer>> itemCollection = basket.values();
Iterator<Map<Item, Integer>> itemIterator =   itemCollection.stream().sorted(new TestComparator()).collect(Collectors.toList()).iterator();



package com.ie.util;

import com.ie.item.Item;

import java.util.Comparator;
import java.util.Iterator;
import java.util.Map;
import java.util.Set;

public class TestComparator implements Comparator<Map<Item, Integer>> {

// comparator is used to sort the Items based on the price


    @Override
    public int compare(Map<Item, Integer> o1, Map<Item, Integer> o2) {


      //  System.out.println("*** compare method will be called *****");


        Item item1 = null;
        Item item2 = null;


        Set<Item> itemSet1 = o1.keySet();
        Iterator<Item> itemIterator1 = itemSet1.iterator();
        if(itemIterator1.hasNext()){
           item1 =   itemIterator1.next();
        }

        Set<Item> itemSet2 = o2.keySet();
        Iterator<Item> itemIterator2 = itemSet2.iterator();
        if(itemIterator2.hasNext()){
            item2 =   itemIterator2.next();
        }


        return -item1.getPrice().compareTo(item2.getPrice());


    }
}

**** this is helpful to sort the nested map objects like Map> here i sorted based on the Item object price .

SurfaceView probably does not work like a regular View in this regard.

Instead, do the following:

1. Put your SurfaceView inside of a FrameLayout or RelativeLayout in your layout XML file, since both of those allow stacking of widgets on the Z-axis
2. Move your drawing logic into a separate custom View class
3. Add an instance of the custom View class to the layout XML file as a child of the FrameLayout or RelativeLayout, but have it appear after the SurfaceView

This will cause your custom View class to appear to float above the SurfaceView.

See here for a sample project that layers popup panels above a SurfaceView used for video playback.

For start you can use:

<body style="margin:0;padding:0">

Once you study a bit about css, you can change it to:

body {margin:0;padding:0}

in your stylesheet.

So this question is nearly 10 years old, but it popped up on one of my searches, and I think that there are better solutions when programming in Qt: Signals & slots, timers, and finite state machines. The delays that are required can be implemented without sleeping the application in a way that interrupts other functions, and without concurrent programming and without spinning the processor - the Qt application will sleep when there are no events to process.

A hack for this is to have a sequence of timers with their timeout() signal connected to the slot for the event, which then kicks off the second timer. This is nice because it is simple. It's not so nice because it quickly becomes difficult to troubleshoot and maintain if there are logical branches, which there generally will be outside of any toy example.

QTimer

A better, more flexible option is the State Machine infrastructure within Qt. There you can configure an framework for an arbitrary sequence of events with multiple states and branches. An FSM is much easier to define, expand and maintain over time.

Qt State Machine

Please make sure two things:

1- Use @Bean annotation with the method.

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder){
    return builder.build();
}

2- Scope of this method should be public not private.

Complete Example -

@Service
public class MakeHttpsCallImpl implements MakeHttpsCall {

@Autowired
private RestTemplate restTemplate;

@Override
public String makeHttpsCall() {
    return restTemplate.getForObject("https://localhost:8085/onewayssl/v1/test",String.class);
}

@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder){
    return builder.build();
}
}

you can move to another fragment by using the FragmentManager transactions. Fragment can not be called like activities,. Fragments exists on the existance of activities.

You can call another fragment by writing the code below:

        FragmentTransaction t = this.getFragmentManager().beginTransaction();
        Fragment mFrag = new MyFragment();
        t.replace(R.id.content_frame, mFrag);
        t.commit();

here "R.id.content_frame" is the id of the layout on which you want to replace the fragment.

you can also add the other fragment incase of replace.

you can build and execute dynamic sql to do this, but its really not ideal

Here is an alternative solution:

class extendedWebBrowser : WebBrowser
{
    /// <summary>
    /// Default constructor which will make the browser to ignore all errors
    /// </summary>
    public extendedWebBrowser()
    {
        this.ScriptErrorsSuppressed = true;

        FieldInfo field = typeof(WebBrowser).GetField("_axIWebBrowser2", BindingFlags.Instance | BindingFlags.NonPublic);
        if (field != null)
        {
             object axIWebBrowser2 = field.GetValue(this);
             axIWebBrowser2.GetType().InvokeMember("Silent", BindingFlags.SetProperty, null, axIWebBrowser2, new object[] { true });
        }
    }
}

I ran into the same issue on windows 7. I managed to get it working by creating a "pip" folder with a "pip.ini" file inside it. I put this folder inside "C:\Users\{my.username}\AppData\Roaming", because according to the Python documentation:

On Windows the configuration file is %APPDATA%\pip\pip.ini

In the pip.ini file I have only:

[global]
proxy = [proxy address]:[proxy port]

So no username:password. And it is working just fine.

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

You Need to import the single color transparent PNG image. So You can set the Icon color of the small icon. Otherwise it will be shown white in some devices like MOTO

netstat -ano|grep 443|grep LISTEN

will tell you whether a process is listening on port 443 (you might have to replace LISTEN with a string in your language, though, depending on your system settings).

There's much simpler solution today — pem. This tool makes life much easier.

For example, to generate or renew your push notification certificate just enter:

fastlane pem 

and it's done in under a minute. In case you need a sandbox certificate, enter:

fastlane pem --development

And that's pretty it.

A little late reply, but what I found in Notepad++ v7.8.6 is, on RMB (Right Mouse Button), on selection text, it gives an option called "Style token" where it shows "Using 1st/2nd/3rd/4th/5th style" to highlight the selected text in different pre-defined colors

You are missing that rsync can also compare files by checksum.

--size-only means that rsync will skip files that match in size, even if the timestamps differ. This means it will synchronise fewer files than the default behaviour. It will miss any file with changes that don't affect the overall file size. If you have something that changes the dates on files without changing the files, and you don't want rsync to spend lots of time checksumming those files to discover they haven't changed, this is the option to use.

--ignore-times means that rsync will checksum every file, even if the timestamps and file sizes match. This means it will synchronise more files than the default behaviour. It will include changes to files even where the file size is the same and the modification date/time has been reset to the original value. Checksumming every file means it has to be entirely read from disk, which may be slow. Some build pipelines will reset timestamps to a specific date (like 1970-01-01) to ensure that the final build file is reproducible bit for bit, e.g. when packed into a tar file that saves the timestamps.

This has been asked so many times so that a user with over 1000 points ask for this is some strange
But just to show just another way to do it:

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

You say you've had problems with Navicat. For the record, I use Navicat and I haven't experienced the issue you describe. You might want to dig around, see if there's a reason for your problem and/or a solution, because given the question asked, my first recommendation would have been Navicat.

But if you want alternative suggestions, here are a few that I know of and have used:

MySQL has its own tool which you can download for free, called MySQL Workbench. Download it from here: http://wb.mysql.com/. My experience is that it's powerful, but I didn't really like the UI. But that's just my personal taste.

Another free program you might want to try is HeidiSQL. It's more similar to Navicat than MySQL Workbench. A colleague of mine loves it.

(interesting to note, by the way, that MariaDB (the forked version of MySQL) is currently shipped with HeidiSQL as its GUI tool)

Finally, if you're running a web server on your machine, there's always the option of a browser-based tool like PHPMyAdmin. It's actually a surprisingly powerful piece of software.

You could use HorizontalContentAlignment="Stretch" as follows:

<ListBox HorizontalContentAlignment="Stretch"/>

origin/master is the remote master branch

Usually after doing a git fetch origin to bring all the changes from the server, you would do a git rebase origin/master, to rebase your changes and move the branch to the latest index. Here, origin/master is referring to the remote branch, because you are basically telling GIT to rebase the origin/master branch onto the current branch.

You would use origin master when pushing, for example. git push origin master is simply telling GIT to push to the remote repository the local master branch.

@OP it doesn't matter, you can just split on a space with explode. Until you want to use those values, iterate over the exploded values and discard blanks.

$str = "A      B      C      D";
$s = explode(" ",$str);
foreach ($s as $a=>$b){    
    if ( trim($b) ) {
     print "using $b\n";
    }
}

I think it will help you

string filename = String.Format("Results_{0}_{1}.xls", DateTime.Today.Month.ToString(), DateTime.Today.Year.ToString());

WE had this issue. everything was setup fine in terms of permissions and security.

after MUCH needling around in the haystack. the issue was some sort of heuristics. in the email body , anytime a certain email address was listed, we would get the above error message from our exchange server.

it took 2 days of crazy testing and hair pulling to find this.

so if you have checked everything out, try changing the email body to only the word 'test'. If after that, your email goes out fine, you are having some sort of spam/heuristic filter issue like we were

I believe that it can be done by simply setting your FormBorderStyle Property to None and the WindowState to Maximized. If you are using Visual Studio both of those can be found in the IDE so there is no need to do so programmatically. Make sure to include some way of closing/exiting the program before doing this cause this will remove that oh so helpful X in the upper right corner.

EDIT:

Try this instead. It is a snippet that I have kept for a long time. I can't even remember who to credit for it, but it works.

So Soumyaansh's Revo Uninstaller Pro fix worked for me :) ( After 2 days of troubleshooting other options {screams internally 😀} ).

I did run into the an issue with his method though, "Could not find a suitable SDK to target" even though I selected to install Visual Studio with custom settings and selected the SDK I wanted to install. You may need to download the Windows 10 Standalone SDK to resolved this, in order to develop UWP apps if you see this same error after reinstalling Visual Studio.

To do this

1. Uninstall any Windows 10 SDKs that me on the system (the naming schem for them looks like Windows 10 SDK (WINDOWS_VERSION_NUMBER_HERE) -> Windows 10 SDK (14393) etc . . .). If there are no SDKs on your system go to step 2!
2. All that's left is to download the SDKs you want by Checking out the SDK Archive for all available SDKs and you should be good to go in developing for the UWP!

set anonymous access in your virtual directory

write following credentials to your service

adtService.ClientCredentials.Windows.ClientCredential.UserName="windowsuseraccountname";
adtService.ClientCredentials.Windows.ClientCredential.Password="windowsuseraccountpassword";
adtService.ClientCredentials.Windows.ClientCredential.Domain="windowspcname";

after that you call your webservice methods.

If you want to cut being careful to don't split words you can do the following

function ellipse($str,$n_chars,$crop_str=' [...]')
{
    $buff=strip_tags($str);
    if(strlen($buff) > $n_chars)
    {
        $cut_index=strpos($buff,' ',$n_chars);
        $buff=substr($buff,0,($cut_index===false? $n_chars: $cut_index+1)).$crop_str;
    }
    return $buff;
}

if $str is shorter than $n_chars returns it untouched.

If $str is equal to $n_chars returns it as is as well.

if $str is longer than $n_chars then it looks for the next space to cut or (if no more spaces till the end) $str gets cut rudely instead at $n_chars.

NOTE: be aware that this method will remove all tags in case of HTML.

Try > workdirectory/filename.txt

This would:

• truncate the file if it exists
• create if it doesn't exist

You can consider it equivalent to:

rm -f workdirectory/filename.txt; touch workdirectory/filename.txt

TL;DR

Here's a version where you don't need a human to read a value and type it out themselves.

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq'); 

Another option would be to employ the reusable Function shared at the end of this answer.

A non-interactive solution

Just adding to the other two answers, for those of us who need to have these Sequences created by a non-interactive script, while patching a live-ish DB for instance.

That is, when you don't wanna SELECT the value manually and type it yourself into a subsequent CREATE statement.

In short, you can not do:

CREATE SEQUENCE foo_a_seq
    START WITH ( SELECT max(a) + 1 FROM foo );

... since the START [WITH] clause in CREATE SEQUENCE expects a value, not a subquery.

Note: As a rule of thumb, that applies to all non-CRUD (i.e.: anything other than INSERT, SELECT, UPDATE, DELETE) statements in pgSQL AFAIK.

However, setval() does! Thus, the following is absolutely fine:

SELECT setval('foo_a_seq', max(a)) FROM foo;

If there's no data and you don't (want to) know about it, use coalesce() to set the default value:

SELECT setval('foo_a_seq', coalesce(max(a), 0)) FROM foo;
--                         ^      ^         ^
--                       defaults to:       0

However, having the current sequence value set to 0 is clumsy, if not illegal.
Using the three-parameter form of setval would be more appropriate:

--                                             vvv
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
--                                                  ^   ^
--                                                is_called

Setting the optional third parameter of setval to false will prevent the next nextval from advancing the sequence before returning a value, and thus:

the next nextval will return exactly the specified value, and sequence advancement commences with the following nextval.

— from this entry in the documentation

On an unrelated note, you also can specify the column owning the Sequence directly with CREATE, you don't have to alter it later:

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;

In summary:

CREATE SEQUENCE foo_a_seq OWNED BY foo.a;
SELECT setval('foo_a_seq', coalesce(max(a), 0) + 1, false) FROM foo;
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq'); 

Using a Function

Alternatively, if you're planning on doing this for multiple columns, you could opt for using an actual Function.

CREATE OR REPLACE FUNCTION make_into_serial(table_name TEXT, column_name TEXT) RETURNS INTEGER AS $$
DECLARE
    start_with INTEGER;
    sequence_name TEXT;
BEGIN
    sequence_name := table_name || '_' || column_name || '_seq';
    EXECUTE 'SELECT coalesce(max(' || column_name || '), 0) + 1 FROM ' || table_name
            INTO start_with;
    EXECUTE 'CREATE SEQUENCE ' || sequence_name ||
            ' START WITH ' || start_with ||
            ' OWNED BY ' || table_name || '.' || column_name;
    EXECUTE 'ALTER TABLE ' || table_name || ' ALTER COLUMN ' || column_name ||
            ' SET DEFAULT nextVal(''' || sequence_name || ''')';
    RETURN start_with;
END;
$$ LANGUAGE plpgsql VOLATILE;

Use it like so:

INSERT INTO foo (data) VALUES ('asdf');
-- ERROR: null value in column "a" violates not-null constraint

SELECT make_into_serial('foo', 'a');
INSERT INTO foo (data) VALUES ('asdf');
-- OK: 1 row(s) affected

I went through all answers nothing helped much. In my case problem with web.config file. It was <compilation debug="false" strict="true"

I changed to

<compilation debug="true" strict="false". Now I can debug application.

Spent a couple hours trying to fix this.

Re-connecting my wifi did the trick.

Maybe you want to use twill. It's quite easy to use and should be able to do what you want.

It will look like the following:

from twill.commands import *
go('http://example.org')

fv("1", "email-email", "blabla.com")
fv("1", "password-clear", "testpass")

submit('0')

You can use showforms() to list all forms once you used go… to browse to the site you want to login. Just try it from the python interpreter.

There's only one registered mediatype for SVG, and that's the one you listed, image/svg+xml. You can of course serve SVG as XML too, though browsers tend to behave differently in some scenarios if you do, for example I've seen cases where SVG used in CSS backgrounds fail to display unless served with the image/svg+xml mediatype.

This works fine:

os.path.join(dir_name, base_filename + "." + filename_suffix)

Keep in mind that os.path.join() exists only because different operating systems use different path separator characters. It smooths over that difference so cross-platform code doesn't have to be cluttered with special cases for each OS. There is no need to do this for file name "extensions" (see footnote) because they are always connected to the rest of the name with a dot character, on every OS.

If using a function anyway makes you feel better (and you like needlessly complicating your code), you can do this:

os.path.join(dir_name, '.'.join((base_filename, filename_suffix)))

If you prefer to keep your code clean, simply include the dot in the suffix:

suffix = '.pdf'
os.path.join(dir_name, base_filename + suffix)

That approach also happens to be compatible with the suffix conventions in pathlib, which was introduced in python 3.4 after this question was asked. New code that doesn't require backward compatibility can do this:

suffix = '.pdf'
pathlib.PurePath(dir_name, base_filename + suffix)

You might prefer the shorter Path instead of PurePath if you're only handling paths for the local OS.

Warning: Do not use pathlib's with_suffix() for this purpose. That method will corrupt base_filename if it ever contains a dot.

Footnote: Outside of Micorsoft operating systems, there is no such thing as a file name "extension". Its presence on Windows comes from MS-DOS and FAT, which borrowed it from CP/M, which has been dead for decades. That dot-plus-three-letters that many of us are accustomed to seeing is just part of the file name on every other modern OS, where it has no built-in meaning.

To check mongodb version use the mongod command with --version option.

To check MongoDB Server version, Open the command line via your terminal program and execute the following command:

Path : C:\Program Files\MongoDB\Server\3.2\bin Open Cmd and execute the following command: mongod --version To Check MongoDB Shell version, Type:

mongo --version

The getRequestURL() omits the port when it is 80 while the scheme is http, or when it is 443 while the scheme is https.

So, just use getRequestURL() if all you want is obtaining the entire URL. This does however not include the GET query string. You may want to construct it as follows then:

StringBuffer requestURL = request.getRequestURL();
if (request.getQueryString() != null) {
    requestURL.append("?").append(request.getQueryString());
}
String completeURL = requestURL.toString();

IF a user has "Print Background colours and images" turned off in their print settings, no CSS will override that, so always account for that. This is a default setting.

Once that is set so it will print background colours and images, what you have there will work.

It is found in different spots. In IE9beta it's found in Print->Page Options under Paper options

In FireFox it's in Page Setup -> [Format & Options] Tab under Options.

I’m running a 5th gen i7 with Windows 10 and a 1TB Solid State. I compressed the Android Studio Projects folder and got about an 80% boost. Hope this helps.

I then combined it with the above solutions ie (org.gradle.parallel=true, org.gradle.daemon=true). The performance boost was quite impressive.

Additionally:

All of the above answers are totally correct but I must state as an experience Android developer (of 4 and a half years) that: No Android/Gradle developer should be working on a machine with a spinner drive, you need to fork out for a Solid State. We all hit that play button in the IDE 100s of times per day. When I went from a spinner to SSD (post Gradle), my speed and efficiency was literally 2 – 4 times faster and I promise you I’m NOT exaggerating here.

Now I’m not talking about having a machine with a small SSD and a big spinner, I’m talking about 1 big SSD. If you already have a machine with a small SSD and a big spinner you can upgrade the small spinner to say a 500GB SSD and set the SSD as your main OS drive with your developer tools installed on it.

So if you’re working in a fast paced environment please show this post to your boss. A decent 1TB SSD will set you back about £300 (including VAT), or about £160 for a 500GB SSD. Depending on if you are a junior or senior Android developer the drive will pay for itself (in wages expenses) in 1 – 2 working weeks, or about 2 and a half to 5 working days if you invest in a smaller; say 500GB SSD.

A lot of developers may argue that this is not the case, but it is the case for Gradle, as the Gradle system is very hard on the direct disk access. If you work with .NET/C#/VB Net or other development tools you won’t notice much difference but the difference in Gradle is HUGE. If you act on this post I promise you, you won’t be disappointed. Personally I’m using fifth gen i7 with 8GB RAM which originally came with a 1TB Spinner and I upgraded it to a Samsung SSD 840 EVO 1TB and I’ve never looked back since. I bought mine from: https://www.aria.co.uk.

Hope this helps. Also I must state that this is NOT a commercially motivated post, I’m just recommending Aria as I’ve used them many times before and they’ve always been reliable.

Based on the answer of Stephen Cagle I added support for nested test modules.

import fnmatch
import os
import unittest

def all_test_modules(root_dir, pattern):
    test_file_names = all_files_in(root_dir, pattern)
    return [path_to_module(str) for str in test_file_names]

def all_files_in(root_dir, pattern):
    matches = []

    for root, dirnames, filenames in os.walk(root_dir):
        for filename in fnmatch.filter(filenames, pattern):
            matches.append(os.path.join(root, filename))

    return matches

def path_to_module(py_file):
    return strip_leading_dots( \
        replace_slash_by_dot(  \
            strip_extension(py_file)))

def strip_extension(py_file):
    return py_file[0:len(py_file) - len('.py')]

def replace_slash_by_dot(str):
    return str.replace('\\', '.').replace('/', '.')

def strip_leading_dots(str):
    while str.startswith('.'):
       str = str[1:len(str)]
    return str

module_names = all_test_modules('.', '*Tests.py')
suites = [unittest.defaultTestLoader.loadTestsFromName(mname) for mname 
    in module_names]

testSuite = unittest.TestSuite(suites)
runner = unittest.TextTestRunner(verbosity=1)
runner.run(testSuite)

The code searches all subdirectories of . for *Tests.py files which are then loaded. It expects each *Tests.py to contain a single class *Tests(unittest.TestCase) which is loaded in turn and executed one after another.

This works with arbitrary deep nesting of directories/modules, but each directory in between needs to contain an empty __init__.py file at least. This allows the test to load the nested modules by replacing slashes (or backslashes) by dots (see replace_slash_by_dot).

According to this documentation (a place full of goodies:)):

driver.current_url

or, see official documentation: https://seleniumhq.github.io/docs/site/en/webdriver/browser_manipulation/#get-current-url

As @Agent_9191 and @partick mentioned you should use

$('tbody :visible').highlight(myArray[i]); // works for all children of tbody that are visible

or

$('tbody:visible').highlight(myArray[i]); // works for all visible tbodys

Additionally, since you seem to be applying a class to the highlighted words, instead of using jquery to alter the background for all matched highlights, just create a css rule with the background color you need and it gets applied directly once you assign the class.

.highlight { background-color: #FFFF88; }

If you are entering text into the label beforehand, you can do this.

1. In the designer, Right-Click on the label and click Properties.
2. In Properties, search for text tab.
3. Click in the tab and click on the arrow button next to it.
4. A box will popup on top of it.
5. You can press enter in the popup box to add lines and type as in notepad! (PRESS ENTER WHERE YOU WANT TO WRAP THE LABEL TEXT)

A public item is one that is accessible from any other class. You just have to know what object it is and you can use a dot operator to access it. Protected means that a class and its subclasses have access to the variable, but not any other classes, they need to use a getter/setter to do anything with the variable. A private means that only that class has direct access to the variable, everything else needs a method/function to access or change that data. Hope this helps.

Seems like the general query log is the file that you need. A good introduction to this is at http://dev.mysql.com/doc/refman/5.1/en/query-log.html

To change database owner:

ALTER AUTHORIZATION ON DATABASE::YourDatabaseName TO sa

As of SQL Server 2014 you can still use sp_changedbowner as well, even though Microsoft promised to remove it in the "future" version after SQL Server 2012. They removed it from SQL Server 2014 BOL though.

Step 1: Add the submodule

   git submodule add git://some_repository.git some_repository

Step 2: Fix the submodule to a particular commit

By default the new submodule will be tracking HEAD of the master branch, but it will NOT be updated as you update your primary repository. In order to change the submodule to track a particular commit or different branch, change directory to the submodule folder and switch branches just like you would in a normal repository.

   git checkout -b some_branch origin/some_branch

Now the submodule is fixed on the development branch instead of HEAD of master.

Don't think anyone mentioned the overhead in exception handling - takes additional resources to load up and process the exception so unless its a true app killing or process stopping event (going forward would cause more harm than good) I would opt for passing back a value the calling environment could interpret as it sees fit.

As per my personal experience Adobe edge is the best tool for HTML5. It's still in preview mode but you will download it free from Adobe site.

this.Invoke(delegate) make sure that you are calling the delegate the argument to this.Invoke() on main thread/created thread.

I can say a Thumb rule don't access your form controls except from main thread.

May be the following lines make sense for using Invoke()

    private void SetText(string text)
    {
        // InvokeRequired required compares the thread ID of the
        // calling thread to the thread ID of the creating thread.
        // If these threads are different, it returns true.
        if (this.textBox1.InvokeRequired)
        {   
            SetTextCallback d = new SetTextCallback(SetText);
            this.Invoke(d, new object[] { text });
        }
        else
        {
            this.textBox1.Text = text;
        }

There are situations though you create a Threadpool thread(i.e worker thread) it will run on main thread. It won't create a new thread coz main thread is available for processing further instructions. So First investigate whether the current running thread is main thread using this.InvokeRequired if returns true the current code is running on worker thread so call this.Invoke(d, new object[] { text });

else directly update the UI control(Here you are guaranteed that you are running the code on main thread.)

I believe that storing JSON in a mysql database does in fact defeat the purpose of using RDBMS as it is intended to be used. I would not use it in any data that would be manipulated at some point or reported on, since it not only adds complexity but also could easily impact performance depending on how it is used.

However, I was curious if anyone else thought of a possible reason to actually do this. I was thinking to make an exception for logging purposes. In my case, I want to log requests that have a variable amount of parameters and errors. In this situation, I want to use tables for the type of requests, and the requests themselves with a JSON string of different values that were obtained.

In the above situation, the requests are logged and never manipulated or indexed within the JSON string field. HOWEVER, in a more complex environment, I would probably try to use something that has more of an intention for this type of data and store it with that system. As others have said, it really depends on what you are trying to accomplish, but following standards always helps longevity and reliability!

I installed and deinstalled ajdt-plugin and got the same problem.

Check <Project><Properties><Builders>. It should have a 'Java Builder'.

This code should be in the .project file (file is in the root of your project):

<buildSpec>
        <buildCommand>
                <name>org.eclipse.jdt.core.javabuilder</name>
                <arguments>
                </arguments>
        </buildCommand>
</buildSpec>
<natures>
        <nature>org.eclipse.jdt.core.javanature</nature>
</natures>

You are not calling the function inner, just defining it.

function outer() { 
    function inner() {
        alert("hi");
    }

    inner(); //Call the inner function

}

Local storage: It keeps store the user information data without expiration date this data will not be deleted when user closed the browser windows it will be available for day, week, month and year.

//Set the value in a local storage object
localStorage.setItem('name', myName);

//Get the value from storage object
localStorage.getItem('name');

//Delete the value from local storage object
localStorage.removeItem(name);//Delete specifice obeject from local storege
localStorage.clear();//Delete all from local storege

Session Storage: It is same like local storage date except it will delete all windows when browser windows closed by a web user.

//set the value to a object in session storege
sessionStorage.myNameInSession = "Krishna";

Apparently this would be possible in settings.gradle with something like this.

rootProject.name = 'someName'
gradle.rootProject {
    it.sourceCompatibility = '1.7'
}

I recently received advice that a project property can be set by using a closure which will be called later when the Project is available.

By default, docker uses AF_INET6 sockets which can be used for both IPv4 and IPv6 connections. This causes netstat to report an IPv6 address for the listening address.

If someone like to delay the same function, and without external variable he can use the next script:

function MyFunction() {

    //Delaying the function execute
    if (this.timer) {
        window.clearTimeout(this.timer);
    }
    this.timer = window.setTimeout(function() {

        //Execute the function code here...

    }, 500);
}

in html/js context, on modern browsers, with other iterable objects than Arrays we could also use [Iterable].entries():

for(let [index, element] of document.querySelectorAll('div').entries()) {

    element.innerHTML = '#' + index

}

You should try the HttpWebRequest class.

If using Android 2.2 and above (which is most devices now), the following code will get you what you want.

@Override
public void onBackPressed() {
    if (webView.canGoBack()) {
        webView.goBack();
    } else {
        super.onBackPressed();
    }
}

According to the above answers setdefault() method worked for me.

old_attr_name = mydict.setdefault(key, attr_name)
if attr_name != old_attr_name:
    raise RuntimeError(f"Key '{key}' duplication: "
                       f"'{old_attr_name}' and '{attr_name}'.")

Though this solution is not generic. Just suited me in this certain case. The exact solution would be checking for the key first (as was already advised), but with setdefault() we avoid one extra lookup on the dictionary, that is, though small, but still a performance gain.
