Just close the Project you want to add , then drag and drop the file .

you also need to identify the columns to set dimensions:

foreach (range('A', $phpExcelObject->getActiveSheet()->getHighestDataColumn()) as $col) {
$phpExcelObject
        ->getActiveSheet()
        ->getColumnDimension($col)
        ->setAutoSize(true);
}

this is answer for your question.

GridViewRow gvr = (GridViewRow)((ImageButton)e.CommandSource).NamingContainer;

int RowIndex = gvr.RowIndex; 

A little update for Bootstrap 3.

Bootstrap now has the following style for table cells:

.table tbody>tr>td
{
    vertical-align: top;
}

The way to go is to add a your own class, with the same selector:

.table tbody>tr>td.vert-align
{
    vertical-align: middle;
}

And then add it to your tds

<td class="vert-align"></td>

Just a quick addition to @TimGilbert's old-school answer...you can make your abstract base class's init() method throw an exception and that would prevent it from being instantiated, no?

>>> class Abstract(object):
...     def __init__(self):
...         raise NotImplementedError("You can't instantiate this class!")
...
>>> a = Abstract()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in __init__
NotImplementedError: You can't instantiate this class! 

dancavallaro has it right, %* for all command line parameters (excluding the script name itself). You might also find these useful:

%0 - the command used to call the batch file (could be foo, ..\foo, c:\bats\foo.bat, etc.)
%1 is the first command line parameter,
%2 is the second command line parameter,
and so on till %9 (and SHIFT can be used for those after the 9th).

%~nx0 - the actual name of the batch file, regardless of calling method (some-batch.bat)
%~dp0 - drive and path to the script (d:\scripts)
%~dpnx0 - is the fully qualified path name of the script (d:\scripts\some-batch.bat)

More info examples at https://www.ss64.com/nt/syntax-args.html and https://www.robvanderwoude.com/parameters.html

Try this solution.

$mainModelData = mainModel::where('column', $value)
    ->join('relationModal', 'main_table_name.relation_table_column', '=', 'relation_table.id')
    ->orderBy('relation_table.title', 'ASC')
    ->with(['relationModal' => function ($q) {
        $q->where('column', 'value');
    }])->get();

Example:

$user = User::where('city', 'kullu')
    ->join('salaries', 'users.id', '=', 'salaries.user_id')
    ->orderBy('salaries.amount', 'ASC')
    ->with(['salaries' => function ($q) {
        $q->where('amount', '>', '500000');
    }])->get();

You can change the column name in join() as per your database structure.

A pretty nice way to do this is to use SimpleDateFormat I'll show you how:

SimpleDateFormat sdf = new SimpleDateFormat("d MMMM YYYY");
Date d = new Date();
sdf.format(d);

I see that you have the date in a variable:

sdf.format(variable_name);

Cheers.

Here's one way:

CString str;
str.Format("%d", 5);

In your case, try _T("%d") or L"%d" rather than "%d"

It seems like you can also use the patch command. Put the diff in the root of the repository and run patch from the command line.

patch -i yourcoworkers.diff

or

patch -p0 -i yourcoworkers.diff

You may need to remove the leading folder structure if they created the diff without using --no-prefix.

If so, then you can remove the parts of the folder that don't apply using:

patch -p1 -i yourcoworkers.diff

The -p(n) signifies how many parts of the folder structure to remove.

More information on creating and applying patches here.

You can also use

git apply yourcoworkers.diff --stat 

to see if the diff by default will apply any changes. It may say 0 files affected if the patch is not applied correctly (different folder structure).

No, that's not possible. The port is not part of the hostname, so it has no meaning in the hosts-file.

If you can modify the HTML: http://jsfiddle.net/8JwhZ/3/

<div class="title">
  <span class="name">Cumulative performance</span>
  <span class="date">20/02/2011</span>
</div>

.title .date { float:right }
.title .name { float:left }

Set the default value for the active argument in the route.

This functionality can also be added using JavaScript. Carto.net has an example:

http://old.carto.net/papers/svg/textFlow/

Something else that also might be useful to are you are editable text areas:

You will need to add a "kernel" for it. Run your enviroment:

>activate tensorflow

Then add a kernel by command (after --name should follow your env. with tensorflow):

>python -m ipykernel install --user --name tensorflow --display-name "TensorFlow-GPU"

After that run jupyter notebook from your tensorflow env.

>jupyter notebook

And then you will see the following enter image description here

Click on it and then in the notebook import packages. It will work out for sure.

Add -L/opt/lib to your compiler parameters, this makes the compiler and linker search that path for libcalc.so in that folder.

If you are using linux system then you need to add

using namespace std;

Below headers

If windows then make sure you put headers correctly #include<iostream.h>

#include<string.h>

Refer this it work perfectly.

#include <iostream>
#include <string>

int main ()
{
std::string str="We think in generalities, but we live in details.";
                                       // (quoting Alfred N. Whitehead)

  std::string str2 = str.substr (3,5);     // "think"

   std::size_t pos = str.find("live");      // position of "live" in str

  std::string str3 = str.substr (pos);     
// get from "live" to the end

  std::cout << str2 << ' ' << str3 << '\n';

  return 0;
}

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

I was pondering a similar problem when asking how the view model for a task or dialog should look like.

My current solution looks like this:

public class SelectionTaskModel<TChoosable> : ViewModel
    where TChoosable : ViewModel
{
    public SelectionTaskModel(ICollection<TChoosable> choices);
    public ReadOnlyCollection<TChoosable> Choices { get; }
    public void Choose(TChoosable choosen);
    public void Abort();
}

When the view model decides that user input is required, it pulls up a instance of SelectionTaskModel with the possible choices for the user. The infrastructure takes care of bringing up the corresponding view, which in proper time will call the Choose() function with the user's choice.

_stats/indices gives the result with indices.

$ curl -XGET "localhost:9200/_stats/indices?pretty=true"
{
  "_shards" : {
    "total" : 10,
    "successful" : 5,
    "failed" : 0
  },
  "_all" : {
    "primaries" : { },
    "total" : { }
  },
  "indices" : {
    "visitors" : {
      "primaries" : { },
      "total" : { }
    }
  }
}

tl;dr non-capturing groups, as the name suggests are the parts of the regex that you do not want to be included in the match and ?: is a way to define a group as being non-capturing.

Let's say you have an email address [email protected]. The following regex will create two groups, the id part and @example.com part. (\p{Alpha}*[a-z])(@example.com). For simplicity's sake, we are extracting the whole domain name including the @ character.

Now let's say, you only need the id part of the address. What you want to do is to grab the first group of the match result, surrounded by () in the regex and the way to do this is to use the non-capturing group syntax, i.e. ?:. So the regex (\p{Alpha}*[a-z])(?:@example.com) will return just the id part of the email.

Using a $where query will be slow, in part because it can't use indexes. For this sort of problem, I think it would be better to store a high value for the "expires" field that will naturally always be greater than Now(). You can either store a very high date millions of years in the future, or use a separate type to indicate never. The cross-type sort order is defined at here.

An empty Regex or MaxKey (if you language supports it) are both good choices.

Apple push will reject a string for a variety of reasons. I tested a variety of scenarios for push delivery, and this was my working fix (in python):

#  Apple rejects push payloads > 256 bytes (truncate msg to < 120 bytes to be safe)
if len(push_str) > 120:
    push_str = push_str[0:120-3] + '...'

# Apple push rejects all quotes, remove them
import re
push_str = re.sub("[\"']", '', push_str)

# Apple push needs to newlines escaped
import MySQLdb
push_str = MySQLdb.escape_string(push_str)

# send it
import APNSWrapper
wrapper = APNSWrapper.APNSNotificationWrapper(certificate=...)
message = APNSWrapper.APNSNotification()
message.token(...)
message.badge(1)
message.alert(push_str)
message.sound("default")
wrapper.append(message)
wrapper.notify()

Here's another answer. It works fast, reliably (see atomicules' answer) and has compact calling code:

' Returns true if item is in the array; false otherwise.
Function IsInArray(ar, item$) As Boolean
    Dim delimiter$, list$

    ' Chr(7) is the ASCII 'Bell' Character.
    ' It was chosen for being unlikely to be found in a normal array.
    delimiter = Chr(7)

    ' Create a list string containing all the items in the array separated by the delimiter.
    list = delimiter & Join(ar, delimiter) & delimiter

    IsInArray = InStr(list, delimiter & item & delimiter) > 0
End Function

Sample usage:

Sub test()
    Debug.Print "Is 'A' in the list?", IsInArray(Split("A,B", ","), "A")
End Sub

Just had this issue deploying a new app to an old IIS box. The investigation led to the v4.5.1 run-time being installed but the app requiring v4.5.2

Nothing apart from installing the correct version of ASP .Net run-time was required.

On Yosemite OSX, use this command:

sed -e 's/^M$//' -i '' filename

where the ^M sequence is achieved by pressing Ctrl+V then Enter.

I made an improvement in order to obtain not only the blocked processes but also the blocking process:

DECLARE @Table TABLE
    (
    SPID INT, Status VARCHAR(MAX), LOGIN VARCHAR(MAX), HostName VARCHAR(MAX), BlkBy VARCHAR(MAX), DBName VARCHAR(MAX), Command VARCHAR(MAX), CPUTime INT, DiskIO INT, LastBatch VARCHAR(MAX), ProgramName VARCHAR(MAX), SPID_1 INT, REQUESTID INT
    )

INSERT INTO @Table EXEC sp_who2

SELECT  *
FROM    @Table
WHERE
    BlkBy not like '  .'
    or
    SPID in (SELECT  BlkBy from @Table where BlkBy not like '  .')

delete from @Table

Scenario 1: You had Eclipse showing server and now after removing the particular version you want to configure at Eclipse a new local server instance. But you can not move further.

This happens due to reason Eclipse still looks for configured version of Tomcat directory, which directory is no longer there.

There is no need till LUNA to make fresh installation!

All we need is to REPLACE the new server run time environment into eclipse after removing old one, which is non-existent. Eclipse will

Before the days of jQuery you would use:

   document.getElementById('findmebyid');

If this one line will save you an entire jQuery library, it might be worth while using it instead.

For those concerned about performance: Beginning your selector with an ID is always best as it uses native function document.getElementById.

// Fast:
$( "#container div.robotarm" );

// Super-fast:
$( "#container" ).find( "div.robotarm" );

In phpmyadmin, perform the following:

select @@GLOBAL.sql_mode

In my case, I get the following:

ONLY_FULL_GROUP_BY, STRICT_TRANS_TABLES ,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Copy this result and remove STRICT_TRANS_TABLES. Then perform the following:

set GLOBAL sql_mode='ONLY_FULL_GROUP_BY,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION'

You might have forgotten to auto increment the id field.

The problem doesn't seem to be with the variable but rather with the declaration of ACTInterface. Is ACTInterface declared as internal by any chance?

If you are using an in-memory collection as your filter, it's probably best to use the negation of Contains(). Note that this can fail if the list is too long, in which case you will need to choose another strategy (see below for using a strategy for a fully DB-oriented query).

   var exceptionList = new List<string> { "exception1", "exception2" };

   var query = myEntities.MyEntity
                         .Select(e => e.Name)
                         .Where(e => !exceptionList.Contains(e.Name));

If you're excluding based on another database query using Except might be a better choice. (Here is a link to the supported Set extensions in LINQ to Entities)

   var exceptionList = myEntities.MyOtherEntity
                                 .Select(e => e.Name);

   var query = myEntities.MyEntity
                         .Select(e => e.Name)
                         .Except(exceptionList);

This assumes a complex entity in which you are excluding certain ones depending some property of another table and want the names of the entities that are not excluded. If you wanted the entire entity, then you'd need to construct the exceptions as instances of the entity class such that they would satisfy the default equality operator (see docs).

Simply put OAuth is a way for applications to gain credentials to your information without directly getting your user login information to some website. For example if you write an application on your own website and want it to use data from a user's facebook account, you can use OAuth to get a token via a callback url and then use that token to make calls to the facebook API to get their use data until the token expires. Websites rely on it because it allows programmers to access their data without the user having to directly disclose their information and spread their credentials around online but still provide a level of protection to the data. Will it become the de facto method of authorization? Perhaps, it's been gaining a lot of support recently from Twitter, Facebook, and the likes where other programmers want to build applications around user data.

If I've understood your problem correctly, there are two possible problems here:

• resultset is null - I assume that this can't be the case as if it was you'd get an exception in your while loop and nothing would be output.
• The second problem is that resultset.getString(i++) will get columns 1,2,3 and so on from each subsequent row.

I think that the second point is probably your problem here.

Lets say you only had 1 row returned, as follows:

Col 1, Col 2, Col 3 
A    ,     B,     C

Your code as it stands would only get A - it wouldn't get the rest of the columns.

I suggest you change your code as follows:

ResultSet resultset = ...;
ArrayList<String> arrayList = new ArrayList<String>(); 
while (resultset.next()) {                      
    int i = 1;
    while(i <= numberOfColumns) {
        arrayList.add(resultset.getString(i++));
    }
    System.out.println(resultset.getString("Col 1"));
    System.out.println(resultset.getString("Col 2"));
    System.out.println(resultset.getString("Col 3"));                    
    System.out.println(resultset.getString("Col n"));
}

Edit:

To get the number of columns:

ResultSetMetaData metadata = resultset.getMetaData();
int numberOfColumns = metadata.getColumnCount();

I'm now partial to this style.

I've named your form, and added an 'onClick' to your select_all box.

I've also excluded the 'select_all' checkbox from the jquery selector to keep the internet from blowing up when someone clicks it.

 function toggleSelect(formname) {
   // select the form with the name 'formname', 
   // then all the checkboxes named 'select[]'
   // then 'click' them
   $('form[name='+formname+'] :checkbox[name="select[]"]').click()
 }

 <form name="myform">
   <tr>
        <td><input type="checkbox" id="select_all"    
                   onClick="toggleSelect('myform')" />
        </td>
    </tr>
    <tr>
        <td><input type="checkbox" name="select[]"/></td>
    </tr>
    <tr>
        <td><input type="checkbox" name="select[]"/></td>

1.A very direct and easy to use example, make object to be passed implement Serializable.

class Object implements Serializable{
    String firstName;
   String lastName;
}

2.pass object in bundle

Bundle bundle = new Bundle();
Object Object = new Object();
bundle.putSerializable("object", object);

3.get passed object from bundle as Serializable then cast to Object.

Object object = (Object) getArguments().getSerializable("object");

The best approach to use CData sections for the string in strings.xml file to get a actual display of the html content to the TextView the below code snippet will give you the fair idea.

//in string.xml file
<string name="welcome_text"><![CDATA[<b>Welcome,</b> to the forthetyroprogrammers blog Logged in as:]]> %1$s.</string>

//and in Java code
String welcomStr=String.format(getString(R.string.welcome_text),username);
tvWelcomeUser.setText(Html.fromHtml(welcomStr));

CData section in string text keeps the html tag data intact even after formatting text using String.format method. So, Html.fromHtml(str) works fine and you’ll see the bold text in Welcome message.

Output:

Welcome, to your favorite music app store. Logged in as: username

Here are two functions to calculate distance and bearing, which are based on the code in previous messages and https://gist.github.com/jeromer/2005586 (added tuple type for geographical points in lat, lon format for both functions for clarity). I tested both functions and they seem to work right.

#coding:UTF-8
from math import radians, cos, sin, asin, sqrt, atan2, degrees

def haversine(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = pointA[0]
    lon1 = pointA[1]

    lat2 = pointB[0]
    lon2 = pointB[1]

    # convert decimal degrees to radians 
    lat1, lon1, lat2, lon2 = map(radians, [lat1, lon1, lat2, lon2]) 

    # haversine formula 
    dlon = lon2 - lon1 
    dlat = lat2 - lat1 
    a = sin(dlat/2)**2 + cos(lat1) * cos(lat2) * sin(dlon/2)**2
    c = 2 * asin(sqrt(a)) 
    r = 6371 # Radius of earth in kilometers. Use 3956 for miles
    return c * r


def initial_bearing(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = radians(pointA[0])
    lat2 = radians(pointB[0])

    diffLong = radians(pointB[1] - pointA[1])

    x = sin(diffLong) * cos(lat2)
    y = cos(lat1) * sin(lat2) - (sin(lat1)
            * cos(lat2) * cos(diffLong))

    initial_bearing = atan2(x, y)

    # Now we have the initial bearing but math.atan2 return values
    # from -180° to + 180° which is not what we want for a compass bearing
    # The solution is to normalize the initial bearing as shown below
    initial_bearing = degrees(initial_bearing)
    compass_bearing = (initial_bearing + 360) % 360

Try insmod instead of modprobe. Modprobe looks in the module directory /lib/modules/uname -r for all the modules and other files

Years later i had the same problem. My solution is the creation of a temporary batchfile and another instance of sqlplus:

In first SQL-Script:

:
set echo off
spool sqlsub_tmp.bat
prompt cd /D D:\some\dir
prompt sqlplus user/passwd@tnsname @second_script.sql
spool off
host sqlsub_tmp.bat
host del sqlsub_tmp.bat
:

Note that "second_script.sql" needs an "exit" statement at end if you want to return to the first one..

In C++-11 you can do:

std::vector<int> v = {0, 1, 2, 3, 4, 5};
for (auto i : v)
{
   // access by value, the type of i is int
   std::cout << i << ' ';
}
std::cout << '\n';

See here for variations: https://en.cppreference.com/w/cpp/language/range-for

There are many ways to do this, but since I didn't see any using reduce() I put it here. Maybe it seems utils to someone.

var list = {
    "you": 100,
    "me": 75,
    "foo": 116,
    "bar": 15
};

let result = Object.keys(list).sort((a,b)=>list[a]>list[b]?1:-1).reduce((a,b)=> {a[b]=list[b]; return a},{});

console.log(result);

Also, if you have two subsequent words in regular text and you want to avoid a line break between them, you can use the ~ character.

For example:

As we can see in Fig.~\ref{BlaBla}, there is nothing interesting to see. A~better place..

This can ensure that you don't have a line starting with a figure number (without the Fig. part) or with an uppercase A.

Since you have updated your label client side, you'll need a post-back in order for you're server side code to reflect the changes.

If you do not know how to do this, here is how I've gone about it in the past.

Create a hidden field:

<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />

Create a button that has both client side and server side functions attached to it. You're client side function will populate your hidden field, and the server side will read it. Be sure you're client side is being called first.

<asp:Button ID="_Submit" runat="server" Text="Submit Button" OnClientClick="TestSubmit();" OnClick="_Submit_Click" />

Javascript Client Side Function:

function TestSubmit() {
              try {

             var message = "Message to Pass";
             document.getElementById('__EVENTTARGET').value = message;

           } catch (err) {
              alert(err.message);

          }

      }

C# Server Side Function

protected void _Submit_Click(object sender, EventArgs e)
{
     // Hidden Value after postback
     string hiddenVal= Request.Form["__EVENTTARGET"];
}

Hope this helps!

While I think this compiler error is a good thing, there is a way you can work around it. Use a condition you know will be true:

public void myMethod(){

    someCodeHere();

    if(1 < 2) return; // compiler isn't smart enough to complain about this

    moreCodeHere();

}

The compiler is not smart enough to complain about that.

After you use WhenAll, you can pull the results out individually with await:

var catTask = FeedCat();
var houseTask = SellHouse();
var carTask = BuyCar();

await Task.WhenAll(catTask, houseTask, carTask);

var cat = await catTask;
var house = await houseTask;
var car = await carTask;

You can also use Task.Result (since you know by this point they have all completed successfully). However, I recommend using await because it's clearly correct, while Result can cause problems in other scenarios.

Please follow below step to do some processing after Application Context get loaded i.e application is ready to serve.

1. Create below annotation i.e

   @Retention(RetentionPolicy.RUNTIME) @Target(value= {ElementType.METHOD, ElementType.TYPE}) public @interface AfterApplicationReady {}

2.Create Below Class which is a listener which get call on application ready state.

    @Component
    public class PostApplicationReadyListener implements ApplicationListener<ApplicationReadyEvent> {

    public static final Logger LOGGER = LoggerFactory.getLogger(PostApplicationReadyListener.class);
    public static final String MODULE = PostApplicationReadyListener.class.getSimpleName();

    @Override
    public void onApplicationEvent(ApplicationReadyEvent event) {
        try {
            ApplicationContext context = event.getApplicationContext();
            String[] beans = context.getBeanNamesForAnnotation(AfterAppStarted.class);

            LOGGER.info("bean found with AfterAppStarted annotation are : {}", Arrays.toString(beans));

            for (String beanName : beans) {
                Object bean = context.getBean(beanName);
                Class<?> targetClass = AopUtils.getTargetClass(bean);
                Method[] methods = targetClass.getMethods();
                for (Method method : methods) {
                    if (method.isAnnotationPresent(AfterAppStartedComplete.class)) {

                        LOGGER.info("Method:[{} of Bean:{}] found with AfterAppStartedComplete Annotation.", method.getName(), beanName);

                        Method currentMethod = bean.getClass().getMethod(method.getName(), method.getParameterTypes());

                        LOGGER.info("Going to invoke method:{} of bean:{}", method.getName(), beanName);

                        currentMethod.invoke(bean);

                        LOGGER.info("Invocation compeleted method:{} of bean:{}", method.getName(), beanName);
                    }
                }
            }
        } catch (Exception e) {
            LOGGER.warn("Exception occured : ", e);
        }
    }
}

Finally when you start your Spring application just before log stating application started your listener will be called.

You can also use "or" operator,

for( int i = 0 ; i < 100 || someOtherCondition() ; i++ ) {
  ...
}

I had the same problem. My customer ordered me Python 3.4 script that updates XLS (not XLSX) Excel files.

The 1st package xlrd was installed by "pip install" without problems in my Python home.

The 2nd one xlwt needed to say "pip install xlwt-future" to be compatible.

The 3rd one xlutils has no support for Python 3, but I adapted it a little bit and now it works at least for dummy script:

#!C:\Python343\python
from xlutils.copy import copy # http://pypi.python.org/pypi/xlutils
from xlrd import open_workbook # http://pypi.python.org/pypi/xlrd
from xlwt import easyxf # http://pypi.python.org/pypi/xlwt

file_path = 'C:\Dev\Test_upd.xls'
rb = open_workbook('C:\Dev\Test.xls',formatting_info=True)
r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file
wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)
w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy
w_sheet.write(1, 1, 'Value')
wb.save(file_path)

I attached the file here: http://ifolder.su/43507580

Write to [email protected] if it got expired.

P.S.: Some functions are not called in the dummy example, so maybe they will need for an adaptation also. Who wants to do it, fix exceptions one-by-one with a google help. It's not a very difficult task, because the package code is small...

I was looking at the same statistics problems. The approach you are thinking it is good and it will work. (Answer to the sorting has been given)

But in case you are interested in algorithm performance, I think there are a couple of algorithms that have better performance than just sorting the array, one (QuickSelect) is indicated by @bruce-feist's answer and is very well explained.

[Java implementation: https://discuss.leetcode.com/topic/14611/java-quick-select ]

But there is a variation of this algorithm named median of medians, you can find a good explanation on this link: http://austinrochford.com/posts/2013-10-28-median-of-medians.html

Define "necessary".

It is necessary if you want the browser to know what the type of the file is. PHP automatically sets the Content-Type header to text/html if you don't override it so your browser is treating it as an HTML file that doesn't contain any HTML. If your output contained any HTML you'd see very different outcomes. If you were to send:

<b><i>test</i></b>

a Content-Type: text/html would output:

test

whereas Content-Type: text/plain would output:

<b><i>test</i></b>

TLDR Version: If you really are only outputing text then it doesn't really matter, but it IS wrong.

Just get the millisecond timestamp and add 20 minutes to it:

twentyMinutesLater = new Date(currentDate.getTime() + (20*60*1000))

According to the official ReactJs documentation, you need to pass argument in the default format witch is:

P = {} // default for your props
S = {} // default for yout state

interface Component<P = {}, S = {}> extends ComponentLifecycle<P, S> { }

Or to define your own type like below: (just an exp)

interface IProps {
    clients: Readonly<IClientModel[]>;

    onSubmit: (data: IClientModel) => void;
}

interface IState {
   clients: Readonly<IClientModel[]>;
   loading: boolean;
}

class ClientsPage extends React.Component<IProps, IState> {
  // ...
}

A public class is one option, if you want something more encapsulated you can use an abstract/anonymous class combination. My favorite part is that autocomplete still works (for PhpStorm) for this but I don't have a public class sitting around.

<?php

final class MyParentClass
{
    /**
     * @return MyStruct[]
     */
    public function getData(): array
    {
        return array(
            $this->createMyObject("One", 1.0, new DateTime("now")),
            $this->createMyObject("Two", 2.0, new DateTime("tommorow"))
        );
    }

    private function createMyObject(string $description, float $magnitude, DateTime $timeStamp): MyStruct
    {
        return new class(func_get_args()) extends MyStruct {
            protected function __construct(array $args)
            {
                $this->description = $args[0];
                $this->magnitude = $args[1];
                $this->timeStamp = $args[2];
            }
        };
    }
}

abstract class MyStruct
{
    public string $description;
    public float $magnitude;
    public DateTime $timeStamp;
}

This type of warnings are usually flagged because of the request HTTP headers. Specifically the Accept request header. The MDN documentation for HTTP headers states

The Accept request HTTP header advertises which content types, expressed as MIME types, the client is able to understand. Using content negotiation, the server then selects one of the proposals, uses it and informs the client of its choice with the Content-Type response header. Browsers set adequate values for this header depending of the context where the request is done....

application/json is probably not on the list of MIME types in the Accept header sent by the browser hence the warning.

Solution

Custom HTTP headers can only be sent programmatically via XMLHttpRequest or any of the js library wrappers implementing it.

You can use option:selected to get the chosen option of the select element, then the text() method:

$("select option:selected").text();

Here's an example:

console.log($("select option:selected").text());

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>_x000D_
<select>_x000D_
    <option value="1">Volvo</option>_x000D_
    <option value="2" selected="selected">Saab</option>_x000D_
    <option value="3">Mercedes</option>_x000D_
</select>

Some of the examples here of getting values using coalescing are inefficient.

What you really want is:

return _formsAuthWrapper = _formsAuthWrapper ?? new FormsAuthenticationWrapper();

or

return _formsAuthWrapper ?? (_formsAuthWrapper = new FormsAuthenticationWrapper());

This prevents the object from being recreated every time. Instead of the private variable remaining null and a new object getting created on every request, this ensures the private variable is assigned if the new object is created.

You should add the ngDefaultControl attribute to your input like this:

<md-input
    [(ngModel)]="recipient"
    name="recipient"
    placeholder="Name"
    class="col-sm-4"
    (blur)="addRecipient(recipient)"
    ngDefaultControl>
</md-input>

Taken from comments in this post:

angular2 rc.5 custom input, No value accessor for form control with unspecified name

Note: For later versions of @angular/material:

Nowadays you should instead write:

<md-input-container>
    <input
        mdInput
        [(ngModel)]="recipient"
        name="recipient"
        placeholder="Name"
        (blur)="addRecipient(recipient)">
</md-input-container>

To me, it is better to put the transition codes with the original/minimum selectors than with the :hover or any other additional selectors:

#content #nav a {_x000D_
    background-color: #FF0;_x000D_
    _x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -moz-transition: background-color 1000ms linear;_x000D_
    -o-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}_x000D_
_x000D_
#content #nav a:hover {_x000D_
    background-color: #AD310B;_x000D_
}

<div id="content">_x000D_
    <div id="nav">_x000D_
        <a href="#link1">Link 1</a>_x000D_
    </div>_x000D_
</div>

My first impression was that you were wanting a looping command-prompt with looping user-input inside of that looping command-prompt. (Nested user-input.) Maybe it's not what you wanted, but I already wrote this answer before I realized that. So, I'm going to post it in case other people (or even you) find it useful.

You just need nested loops with an input statement at each loop's level.

For instance,

data=""
while 1:
    data=raw_input("Command: ")
    if data in ("test", "experiment", "try"):
        data2=""
        while data2=="":
            data2=raw_input("Which test? ")
        if data2=="chemical":
            print("You chose a chemical test.")
        else:
            print("We don't have any " + data2 + " tests.")
    elif data=="quit":
        break
    else:
        pass

Make sure you set the 'Start in' and 'Program/script' options correctly. If your file address is: C:\Temp\foo.bat, set the 'start in' option to 'C:\Temp' and the 'Program/script' option to 'foo.bat'.

To set the 'Start in' option: Right click task in the task scheduler > Properties > Actions > Edit.

If this alone doesn't work then try moving the .bat file to a directory with basic permissions (maybe a shared directory for example).

I had a problem where my .bat file was located in a folder with some restrictive permissions on it, so that only my user account could access it. Even though I had set up the task scheduler to use my credentials it still failed. Moving the .bat file to another directory sorted the issue.

You can check the implementation of CPython's dicttype on GitHub. This is the signature of method that implements the dict iterator:

_PyDict_Next(PyObject *op, Py_ssize_t *ppos, PyObject **pkey,
             PyObject **pvalue, Py_hash_t *phash)

CPython dictobject.c

Use:

function getvalues(){
var inps = document.getElementsByName('pname[]');
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
    alert("pname["+i+"].value="+inp.value);
}
}

Here is Demo.

There doesn't seem to be a well defined standard for video metadata (compared to photos and audio files, which have EXIF and ID3/etc. respectively)

Some tags exists like e.g. Title, Composer etc. You can see those if you select a movie file in Windows 7 (perhaps earlier versions also) explorer or right click and view properties. I have not found a tag for recording date unfortunately - the closest thing available is Year (integer) :-(

Programatically, you can read and write most of these tags in .NET using Taglib Sharp from the mono project. Source and binaries are available on the banshee FTP server. It has a pretty impressive list of formats it supports (but still, make sure you catch exceptions when trying to read or write tags - it will throw whenever it finds a file it cannot understand, something which happened to me several times for my modest collection of home recordings.)

To read tags:

using (var f = TagLib.File.Create(@"c:\Path\To\MyVideo.mp4"))
{
    if (f.Tag != null)
    {
        string title = f.Tag.Title;
        Size resolution = new Size(f.Properties.VideoWidth, f.Properties.VideoHeight);
        int year = f.Tag.Year;
        // etc.
    }
}

And similarly, to write metadata back to the file:

using (var f = TagLib.File.Create(@"c:\Path\To\MyVideo.mp4"))
{
    f.Tag.Title = "My Awesome Movie";
    f.Tag.Year = (uint)2011;
    f.Save();
}

You can use the grep alternative sift here (disclaimer: I am the author).

It support multiline matching and limiting the search to specific file types out of the box:

sift -m --files '*.py' 'YOUR_PATTERN'

(search all *.py files for the specified multiline regex pattern)

It is available for all major operating systems. Take a look at the samples page to see how it can be used to to extract multiline values from an XML file.

Use the following:

type file.txt | findstr /v ERROR | findstr /v REFERENCE

This has the advantage of using standard tools in the Windows OS, rather than having to find and install sed/awk/perl and such.

See the following transcript for it in operation:

C:\>type file.txt
Good Line of data
bad line of C:\Directory\ERROR\myFile.dll
Another good line of data
bad line: REFERENCE
Good line

C:\>type file.txt | findstr /v ERROR | findstr /v REFERENCE
Good Line of data
Another good line of data
Good line

The answer to this question lies in how C# Controls work

Controls in Windows Forms are bound to a specific thread and are not thread safe. Therefore, if you are calling a control's method from a different thread, you must use one of the control's invoke methods to marshal the call to the proper thread. This property can be used to determine if you must call an invoke method, which can be useful if you do not know what thread owns a control.

From Control.InvokeRequired

Effectively, what Invoke does is ensure that the code you are calling occurs on the thread that the control "lives on" effectively preventing cross threaded exceptions.

From a historical perspective, in .Net 1.1, this was actually allowed. What it meant is that you could try and execute code on the "GUI" thread from any background thread and this would mostly work. Sometimes it would just cause your app to exit because you were effectively interrupting the GUI thread while it was doing something else. This is the Cross Threaded Exception - imagine trying to update a TextBox while the GUI is painting something else.

• Which action takes priority?
• Is it even possible for both to happen at once?
• What happens to all of the other commands the GUI needs to run?

Effectively, you are interrupting a queue, which can have lots of unforeseen consequences. Invoke is effectively the "polite" way of getting what you want to do into that queue, and this rule was enforced from .Net 2.0 onward via a thrown InvalidOperationException.

To understand what is actually going on behind the scenes, and what is meant by "GUI Thread", it's useful to understand what a Message Pump or Message Loop is.

This is actually already answered in the question "What is a Message Pump" and is recommended reading for understanding the actual mechanism that you are tying into when interacting with controls.

Other reading you may find useful includes:

What's up with Begin Invoke

One of the cardinal rules of Windows GUI programming is that only the thread that created a control can access and/or modify its contents (except for a few documented exceptions). Try doing it from any other thread and you'll get unpredictable behavior ranging from deadlock, to exceptions to a half updated UI. The right way then to update a control from another thread is to post an appropriate message to the application message queue. When the message pump gets around to executing that message, the control will get updated, on the same thread that created it (remember, the message pump runs on the main thread).

and, for a more code heavy overview with a representative sample:

Invalid Cross-thread Operations

// the canonical form (C# consumer)

public delegate void ControlStringConsumer(Control control, string text);  // defines a delegate type

public void SetText(Control control, string text) {
    if (control.InvokeRequired) {
        control.Invoke(new ControlStringConsumer(SetText), new object[]{control, text});  // invoking itself
    } else {
        control.Text=text;      // the "functional part", executing only on the main thread
    }
}

Once you have an appreciation for InvokeRequired, you may wish to consider using an extension method for wrapping these calls up. This is ably covered in the Stack Overflow question Cleaning Up Code Littered with Invoke Required.

There is also a further write up of what happened historically that may be of interest.

The error is due the fact that you are passing a wrong to strcat(). Look at strcat()'s prototype:

   char *strcat(char *dest, const char *src);

But you pass char as the second argument, which is obviously wrong.

Use snprintf() instead.

char str[1024] = "Hello World";
char tmp = '.';
size_t len = strlen(str);

snprintf(str + len, sizeof str - len, "%c", tmp);

As commented by OP:

That was just a example with Hello World to describe the Problem. It must be empty as first in my real program. Program will fill it later. The problem just contains to add a char/int to an char Array

In that case, snprintf() can handle it easily to "append" integer types to a char buffer too. The advantage of snprintf() is that it's more flexible to concatenate various types of data into a char buffer.

For example to concatenate a string, char and an int:

char str[1024];
ch tmp = '.';
int i = 5;

// Fill str here

snprintf(str + len, sizeof str - len, "%c%d", str, tmp, i);

go to your angular project folder and open the command promt an type "ng g component header" where header is the new component that you want to create.As default the header component will be created inside the app component.You can create components inside a component .For example if you want to create a component inside he header that we made above then type"ng g component header/menu". This will create a menu component inside the header component

I was able to set the env. variables by sourcing (source command inside the shell (ksh) scirpt) the file that was settign them. Then I called the .ksh script from the external Tools

Your local branch likely has modifications to it you want to discard. To do this, you'll need to use git reset to reset the branch head to the last spot that you diverged from the upstream repo's branch. Use git branch -v to find the sha1 id of the upstream branch, and reset your branch it it using git reset SHA1ID. Then you should be able to do a git checkout to discard the changes it left in your directory.

Note: always do this on a backed-up repo. That way you can assure you're self it worked right. Or if it didn't, you have a backup to revert to.

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

That code is invalid as you can only pass variables into language constructs. empty() is a language construct.

You have to do this in two lines:

$result = array_intersect($people, $criminals);
$result = !empty($result);

SHOW FULL TABLES IN database_name WHERE TABLE_TYPE LIKE 'VIEW';

Properties of JavaBeans

A JavaBean is a Java object that satisfies certain programming conventions:

1. The JavaBean class must implement either Serializable or Externalizable

2. The JavaBean class must have a no-arg constructor

3. All JavaBean properties must have public setter and getter methods

4. All JavaBean instance variables should be private

Example of JavaBeans

@Entity
public class Employee implements Serializable{

   @Id
   private int id;
   private String name;   
   private int salary;  

   public Employee() {}

   public Employee(String name, int salary) {
      this.name = name;
      this.salary = salary;
   }
   public int getId() {
      return id;
   }
   public void setId( int id ) {
      this.id = id;
   }
   public String getName() {
      return name;
   }
   public void setName( String name ) {
      this.name = name;
   }
   public int getSalary() {
      return salary;
   }
   public void setSalary( int salary ) {
      this.salary = salary;
   }
}

You don't say what class you are using, but I'm guessing it is the standard book. In which case the page clearing is a feature of he class which you can override as Mica suggests, or solve by switching to another class. The standard report class is similar to book, or the memoir class is an improved book and is very flexible indeed.

If your library is set up as an Android library (i.e. it uses the apply plugin: 'com.android.library' statement in its build.gradle file), it will output an .aar when it's built. It will show up in the build/outputs/aar/ directory in your module's directory.

You can choose the "Android Library" type in File > New Module to create a new Android Library.

You could try this SendKeys jQuery plugin:

http://bililite.com/blog/2011/01/23/improved-sendkeys/

$(element).sendkeys(string) inserts string at the insertion point in an input, textarea or other element with contenteditable=true. If the insertion point is not currently in the element, it remembers where the insertion point was when sendkeys was last called (if the insertion point was never in the element, it appends to the end).

In Apache Drill, use backquotes:

select `from` from table;

Use %0D%0A for a line break in your body

• How to enter line break into mailto body command (by Christian Petters; 01 Apr 2008)

Example (Demo):

<a href="mailto:[email protected]?subject=Suggestions&body=name:%0D%0Aemail:">test</a>?
                                                                  ^^^^^^

The other fun thing about null, compared to undefined, is that it can be incremented.

x = undefined_x000D_
x++_x000D_
y = null_x000D_
y++_x000D_
console.log(x) // NaN_x000D_
console.log(y) // 0

This is useful for setting default numerical values for counters. How many times have you set a variable to -1 in its declaration?

Non-reflective solution for Java 8, without using a series of if's, would be to stream all fields and check for nullness:

return Stream.of(id, name).allMatch(Objects::isNull);

This remains quite easy to maintain while avoiding the reflection hammer. This will return true for null attributes.

A generic,simpler and a bit primitive approach to find tag, attribute and value

    Pattern pattern = Pattern.compile("<(\\w+)( +.+)*>((.*))</\\1>");
    System.out.println(pattern.matcher("<asd> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd TEST</asd>").find());
    System.out.println(pattern.matcher("<asd attr='3'> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd> <x>TEST<x>asd>").find());
    System.out.println("-------");
    Matcher matcher = pattern.matcher("<as x> TEST</as>");
    if (matcher.find()) {
        for (int i = 0; i <= matcher.groupCount(); i++) {
            System.out.println(i + ":" + matcher.group(i));
        }
    }

ex mode is easiest:

:%s/$/,

: - enter command mode
% - for every line
s/ - substitute
$ - the end of the line
/ - and change it to
, - a comma

You can refer to it as "snippets" or more accurately "collection of snippets" . The term I think was coined from the press and printing industry, where they used actual "plates" and then re-used them as chunks again.. In modern-day internet it is a part of an ongoing (annoying IMHO) trend of using fancy terms for simple things in order to look more trendy and sophisticated . see RESPONSIVE = adaptable / fluid.

I do not know how efficient this is, However worked for me in a simple context.

List<int> uniqueNumbers = new ArrayList<>();

   public void AddNumberToList(int num)
    {
        if(!uniqueNumbers .contains(num)) {
            uniqueNumbers .add(num);
        }
    }

This will give you the desired result

#!/usr/bin/python

import os

# traverse root directory, and list directories as dirs and files as files
for root, dirs, files in os.walk("."):
    path = root.split(os.sep)
    print((len(path) - 1) * '---', os.path.basename(root))
    for file in files:
        print(len(path) * '---', file)

Use a wild card selector * for this purpose.

#div * { /* Narrowing, to specific elements, like  input, textarea is PREFFERED */
 -webkit-user-select: none;  
  -moz-user-select: none;    
  -ms-user-select: none;      
  user-select: none;
}

Now, every element inside a div with id div will have no selection.

This pointed me in the right direction, but I have a DB that originated in MSSQL 2000 and is still using the ntext data type for the column I was replacing on. When you try to run REPLACE on that type you get this error:

Argument data type ntext is invalid for argument 1 of replace function.

The simplest fix, if your column data fits within nvarchar, is to cast the column during replace. Borrowing the code from the accepted answer:

UPDATE YourTable
SET Column1 = REPLACE(cast(Column1 as nvarchar(max)),'a','b')
WHERE Column1 LIKE '%a%'

This worked perfectly for me. Thanks to this forum post I found for the fix. Hopefully this helps someone else!

Shortest ES6+ one liner:

let exists = Object.values(obj).includes("test1");

Yet another way to execute it (this time without setting execute permissions):

bash /path/to/scriptname

This happens when you run initdb with a user whose ID is not postgres, without specifying the postgres username with --username=postgres or -U postgres.

The database cluster is then created with the system's user account that you used to run initdb, and it is given superuser permissions.

To fix it, simply create a new user named postgres with the option --superuser using the createuser utility that comes with Postgres. The utility can be found in the Postgres' bin directory. e.g.

createuser --superuser postgres

If you have a custom hostname or port then be sure to set the appropriate options.

Don't forget to delete the other user account that was created for you by initdb.

I contribute with my settings for buttons: view, edit and delete. The last column has data: null At the end with the property defaultContent is added a string that HTML code. And since it is the last column, it is indicated with index -1 by means of the targets property when indicating the columns.

Shell works for me.

Simply to say, Shell is the same as you run a shell script.

Notes:

1. Make sure use | when running multiple cmds.
2. Shell won't return errors if the last cmd is success (just like normal shell)
3. Control it with exit 0/1 if you want to stop ansible when error occurs.

The following example shows an error in shell, but it's success at the end of the execution.

- name: test shell with an error
become: no
shell: |
  rm -f /test1  # This should be an error.
  echo "test2"
  echo "test1"
  echo "test3" # success

This example shows stopinng shell with exit 1 error.

- name: test shell with exit 1
become: no
shell: |
  rm -f /test1  # This should be an error.
  echo "test2"
  exit 1        # this stops ansible due to returning an error
  echo "test1"
  echo "test3" # success

reference: https://docs.ansible.com/ansible/latest/modules/shell_module.html

After importing the scripting runtime as described above you have to make some slighty modification to get it working in Excel 2010 (my version). Into the following code I've also add the code used to the user to pick a file.

Dim intChoice As Integer
Dim strPath As String

' Select one file
Application.FileDialog(msoFileDialogOpen).AllowMultiSelect = False

' Show the selection window
intChoice = Application.FileDialog(msoFileDialogOpen).Show

' Get back the user option
If intChoice <> 0 Then
    strPath = Application.FileDialog(msoFileDialogOpen).SelectedItems(1)
Else
    Exit Sub
End If

Dim FSO As New Scripting.FileSystemObject
Dim fsoStream As Scripting.TextStream
Dim strLine As String

Set fsoStream = FSO.OpenTextFile(strPath)

Do Until fsoStream.AtEndOfStream = True
    strLine = fsoStream.ReadLine
    ' ... do your work ...
Loop

fsoStream.Close
Set FSO = Nothing

Hope it help!

You can specify a python write mode in the pandas to_csv function. For append it is 'a'.

In your case:

df.to_csv('my_csv.csv', mode='a', header=False)

The default mode is 'w'.

Commit 59856de from Karsten Blees (kblees) for Git 1.9/2.0 (Q1 2014) clarifies that case:

gitignore.txt: clarify recursive nature of excluded directories

An optional prefix "!" which negates the pattern; any matching file excluded by a previous pattern will become included again.

It is not possible to re-include a file if a parent directory of that file is excluded. (*)
(*: unless certain conditions are met in git 2.8+, see below)
Git doesn't list excluded directories for performance reasons, so any patterns on contained files have no effect, no matter where they are defined.

Put a backslash ("\") in front of the first "!" for patterns that begin with a literal "!", for example, "\!important!.txt".

Example to exclude everything except a specific directory foo/bar (note the /* - without the slash, the wildcard would also exclude everything within foo/bar):

 --------------------------------------------------------------
     $ cat .gitignore
     # exclude everything except directory foo/bar
     /*
     !/foo
     /foo/*
     !/foo/bar
 --------------------------------------------------------------

In your case:

application/*
!application/**/
application/language/*
!application/language/**/
!application/language/gr/**

You must white-list folders first, before being able to white-list files within a given folder.

Update Feb/March 2016:

Note that with git 2.9.x/2.10 (mid 2016?), it might be possible to re-include a file if a parent directory of that file is excluded if there is no wildcard in the path re-included.

Nguy?n Thái Ng?c Duy (pclouds) is trying to add this feature:

• commit 506d8f1 for git v2.7.0, reverted in commit 76b620d git v2.8.0-rc0
• commit 5e57f9c git v2.8.0-rc0,... reverted(!) in commit 5cee3493 git 2.8.0.

So with git 2.9+, this could have actually worked, but was ultimately reverted:

application/
!application/language/gr/

Disable back buttton in android

@Override
public void onBackPressed() {
    return;
}

I could repro this by setting the name of input tag the same for two groups of input like below:

<body>
  <div>
      <div>
        <h3>Header1</h3>
      </div>
      <div>
          <input type="radio" name="gender" id="male_1" value="male"> Male<br>
          <input type="radio" name="gender" id="female_1" value="female" checked="checked"> Female<br>
          <input type="submit" value="Submit">
      </div>
  </div>


  <div>
      <div>
        <h3>Header2</h3>
      </div>
      <div>
          <input type="radio" name="gender" id="male_2" value="male"> Male<br>
          <input type="radio" name="gender" id="female_2" value="female" checked="checked"> Female<br>
          <input type="submit" value="Submit">
      </div>
  </div>
</body>

(To see this running, click here)

The following two solutions both fix the problem:

1. Use different names for the inputs in the second group
2. Use form tag instead of div tag for one of the groups (can't really figure out the real reason why this would solve the problem. Would love to hear some opinions on this!)

Python doesn't care what you pass in to its functions. When you call my_func(a,b), the param1 and param2 variables will then hold the values of a and b. Python doesn't know that you are calling the function with the proper types, and expects the programmer to take care of that. If your function will be called with different types of parameters, you can wrap code accessing them with try/except blocks and evaluate the parameters in whatever way you want.

This should do the trick:

mapper.readValue(fileReader, MyClass.class);

I say should because I'm using that with a String, not a BufferedReader but it should still work.

Here's my code:

String inputString = // I grab my string here
MySessionClass sessionObject;
try {
    ObjectMapper objectMapper = new ObjectMapper();
    sessionObject = objectMapper.readValue(inputString, MySessionClass.class);

Here's the official documentation for that call: http://jackson.codehaus.org/1.7.9/javadoc/org/codehaus/jackson/map/ObjectMapper.html#readValue(java.lang.String, java.lang.Class)

You can also define a custom deserializer when you instantiate the ObjectMapper: http://wiki.fasterxml.com/JacksonHowToCustomDeserializers

Edit: I just remembered something else. If your object coming in has more properties than the POJO has and you just want to ignore the extras you'll want to set this:

    objectMapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);

Or you'll get an error that it can't find the property to set into.

@Context ServletContext ctx;
@Context private HttpServletResponse response;

@GET
@Produces(MediaType.APPLICATION_OCTET_STREAM)
@Path("/download/{filename}")
public StreamingOutput download(@PathParam("filename") String fileName) throws Exception {
    final File file = new File(ctx.getInitParameter("file_save_directory") + "/", fileName);
    response.setHeader("Content-Length", String.valueOf(file.length()));
    response.setHeader("Content-Disposition", "attachment; filename=\""+ file.getName() + "\"");
    return new StreamingOutput() {
        @Override
        public void write(OutputStream output) throws IOException,
                WebApplicationException {
            Utils.writeBuffer(new BufferedInputStream(new FileInputStream(file)), new BufferedOutputStream(output));
        }
    };
}

In response to finding the max value for each column, you could try using the apply() function:

> apply(ozone, MARGIN = 2, function(x) max(x, na.rm=TRUE))
  Ozone Solar.R    Wind    Temp   Month     Day 
   41.0   313.0    20.1    74.0     5.0     9.0 

Simply create a Class Name and define your style there like this :

table.tdfont td {
  font-size: 0.9em;
}

use the below command to set the port number in node process while running node JS programme:

set PORT =3000 && node file_name.js

The set port can be accessed in the code as

process.env.PORT 

I prefer to use an extension method to get the scripts object:

public static IJavaScriptExecutor Scripts(this IWebDriver driver)
{
    return (IJavaScriptExecutor)driver;
}

Used as this:

driver.Scripts().ExecuteScript("some script");

Old question, but I think it deservers a simpler answer.

You can simply do:

var addr = "  ";

if (addr && addr.trim()) {

    console.log("I'm not null, nor undefined, nor empty string, nor string composed of whitespace only.");

}

I think you should indeed be using the Control overload of the RegisterStartupScript.

I've tried the following code in a server control:

[ToolboxData("<{0}:AlertControl runat=server></{0}:AlertControl>")]
public class AlertControl : Control{
    protected override void OnInit(EventArgs e){
        base.OnInit(e);
        string script = "alert(\"Hello!\");";
        ScriptManager.RegisterStartupScript(this, GetType(), 
                      "ServerControlScript", script, true);
    }
}

Then in my page I have:

protected override void OnInit(EventArgs e){
    base.OnInit(e);
    Placeholder1.Controls.Add(new AlertControl());
}

Where Placeholder1 is a placeholder in an update panel. The placeholder has a couple of other controls on in it, including buttons.

This behaved exactly as you would expect, I got an alert saying "Hello" every time I loaded the page or caused the update panel to update.

The other thing you could look at is to hook into some of the page lifecycle events that are fired during an update panel request:

Sys.WebForms.PageRequestManager.getInstance()
   .add_endRequest(EndRequestHandler);

The PageRequestManager endRequestHandler event fires every time an update panel completes its update - this would allow you to call a method to set up your control.

My only other questions are:

• What is your script actually doing?
• Presumably you can see the script in the HTML at the bottom of the page (just before the closing </form> tag)?
• Have you tried putting a few "alert("Here");" calls in your startup script to see if it's being called correctly?
• Have you tried Firefox and Firebug - is that reporting any script errors?

If you specify Owner, you will get a Modal dialog over the specified WPF window.

To get WinForms compatible Win32 window create a class implements IWin32Window like this

 public class OldWindow : System.Windows.Forms.IWin32Window
{
    IntPtr _handle;

    public OldWindow(IntPtr handle)
    {
        _handle = handle;
    }

    #region IWin32Window Members

    IntPtr System.Windows.Forms.IWin32Window.Handle
    {
        get { return _handle; }
    }

    #endregion
}

And use an instance of this class at your WinForms

        IntPtr mainWindowPtr = new WindowInteropHelper(this).Handle; // 'this' means WPF Window
        folderBrowserDialog.ShowDialog(new OldWindow(mainWindowPtr));

I can count the number of days I know Python on my two hands so forgive me if I answer something silly :)

Instead of using a dict, I thought why not use a list? I'm not sure how lists and dictionaries are implemented in Python so this would have to be measured to know what's faster.

If this was C++ I would just use a normal c-array/vector for constant time access (that would definitely be faster) but I don't know what the corresponding datatype is in Python (if there's one...):

count = [0 for i in range(26)]

for c in ''.join(s.lower().split()): # get rid of whitespaces and capital letters
    count[ord(c) - 97] += 1          # ord('a') == 97

It's also possible to make the list's size ord('z') and then get rid of the 97 subtraction everywhere, but if you optimize, why not all the way :)

EDIT: A commenter suggested that the join/split is not worth the possible gain of using a list, so I thought why not get rid of it:

count = [0 for i in range(26)]

for c in s:
    if c.isalpha(): count[ord(c.lower()) - 97] += 1

To expand slightly, if you're doing this with the svn command-line tool, you want to type:

svn propedit svn:ignore path/to/dir

which will open your text-editor of choice, then type '*' to ignore everything inside it, and save+quit - this will include the directory itself in svn, but ignore all the files inside it, to ignore the directory, use the path of the parent, and then type the name of the directory in the file. After saving, run an update ('svn up'), and then check in the appropriate path.

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

From:

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

Probably the best way is to use Guava

List<String> list = new ArrayList<String>();
list.add("How are you");
list.add("How you doing");
list.add("Joe");
list.add("Mike");
    
Collection<String> filtered = Collections2.filter(list,
    Predicates.containsPattern("How"));
print(filtered);

prints

How are you
How you doing

In case you want to get the filtered collection as a list, you can use this (also from Guava):

List<String> filteredList = Lists.newArrayList(Collections2.filter(
    list, Predicates.containsPattern("How")));

Following is the code that i used to have black border. Note that i have not used extra xml file for border.

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/red_minus_icon"
    android:background="#000000"
    android:padding="1dp"/>

you need to post plain javascript object, nothing else

           var request = $http({
                method: "post",
                url: "process.cfm",
                transformRequest: transformRequestAsFormPost,
                data: { id: 4, name: "Kim" }
            });

            request.success(
                function( data ) {
                    $scope.localData = data;
                }
            );

if you have php as back-end then you will need to do some more modification.. checkout this link for fixing php server side

You can add a PPA that provides a relatively current version of SmartGit(as well as SmartGitHg, the predecessor of SmartGit).

To add the PPA run:

sudo add-apt-repository ppa:eugenesan/ppa
sudo apt-get update

To install smartgit (after adding the PPA) run:

sudo apt-get install smartgit

To install smartgithg (after adding the PPA) run:

sudo apt-get install smartgithg

This should add a menu option for you

Edit your AndroidManifest.xml to add RECEIVE_BOOT_COMPLETED permission

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Edit your AndroidManifest.xml application-part for below Permission

<receiver android:enabled="true" android:name=".BootUpReceiver"

I've been using this bit in ~/.gitconfig for a long time:

[diff]
    external = ~/Dropbox/source/bash/git-meld

With git-meld:

#!/bin/bash
if [ "$DISPLAY" = "" ];
then
    diff $2 $5
else
    meld $2 $5
fi

But now I got tired of always using meld in graphical environment, and it's not trivial to invoke the normal diff with this setup, so I switched to this:

[alias]
    v =  "!sh -c 'if [ $# -eq 0 ] ; then git difftool -y -t meld ; else git difftool -y $@ ; fi' -"

With this setup, things like this work:

git v
git v --staged
git v -t kompare
git v --staged -t tkdiff

And I still get to keep the good old git diff.

Felix Kling did a great comparison on those two, for anyone wondering how to do an export default alongside named exports with module.exports in nodejs

module.exports = new DAO()
module.exports.initDAO = initDAO // append other functions as named export

// now you have
let DAO = require('_/helpers/DAO');
// DAO by default is exported class or function
DAO.initDAO()

string s= string.Empty

for (int i = 0; i < Chkboxlist.Items.Count; i++)

{

    if (Chkboxlist.Items[i].Selected)
    {
        s+= Chkboxlist.Items[i].Value + ";"; 
    }

}

My personal practice is .bash_profile. I'm adding paths there and append to Path variable,

GOPATH=/usr/local/go/bin/
MYSQLPATH=/usr/local/opt/[email protected]/bin

PATH=$PATH:$GOPATH:$MYSQLPATH

After then I can have individual Path by echo $GOPATH, echo$MYSQLPATH or all by echo $PATH.

You're comparing the object references, and they are not the same. You need to compare the array contents.

.NET2 solution

An option is iterating through the array elements and call Equals() for each element. Remember that you need to override the Equals() method for the array elements, if they are not the same object reference.

An alternative is using this generic method to compare two generic arrays:

static bool ArraysEqual<T>(T[] a1, T[] a2)
{
    if (ReferenceEquals(a1, a2))
        return true;

    if (a1 == null || a2 == null)
        return false;

    if (a1.Length != a2.Length)
        return false;

    var comparer = EqualityComparer<T>.Default;
    for (int i = 0; i < a1.Length; i++)
    {
        if (!comparer.Equals(a1[i], a2[i])) return false;
    }
    return true;
}

.NET 3.5 or higher solution

Or use SequenceEqual if Linq is available for you (.NET Framework >= 3.5)

I'm surprised nobody has mentioned pathlib's with_name. This solution works with multiple extensions (i.e. it replaces all of the extensions.)

import pathlib

p = pathlib.Path('/some/path/somefile.txt')
p = p.with_name(p.stem).with_suffix('.jpg')

To supply an example of why it has to be a string:

If you format 1.toFixed(2) you would get '1.00'.

This is not the same as 1, as 1 does not have 2 decimals.

I know JavaScript isn't exactly a performance language, but chances are you'd get better performance for a rounding if you use something like: roundedValue = Math.round(value * 100) * 0.01

Same answer as here.

If you want a non-regex ASCII A-z 0-9 check, you cannot use char.IsLetterOrDigit() as that includes other Unicode characters.

What you can do is check the character code ranges.

• 48 -> 57 are numerics
• 65 -> 90 are capital letters
• 97 -> 122 are lower case letters

The following is a bit more verbose, but it's for ease of understanding rather than for code golf.

    public static bool IsAsciiAlphaNumeric(this string str)
    {
        if (string.IsNullOrEmpty(str))
        {
            return false;
        }

        for (int i = 0; i < str.Length; i++)
        {
            if (str[i] < 48) // Numeric are 48 -> 57
            {
                return false;
            }

            if (str[i] > 57 && str[i] < 65) // Capitals are 65 -> 90
            {
                return false;
            }

            if (str[i] > 90 && str[i] < 97) // Lowers are 97 -> 122
            {
                return false;
            }

            if (str[i] > 122)
            {
                return false;
            }
        }

        return true;
    }

To find the highest (max) or lowest (min) value from an array, this could give you the right direction. Here is an example code for getting the highest value from a primitive array.

Method 1:

public int maxValue(int array[]){
  List<Integer> list = new ArrayList<Integer>();
  for (int i = 0; i < array.length; i++) {
    list.add(array[i]);
  }
 return Collections.max(list);

}

To get the lowest value, you can use

Collections.min(list)

Method 2:

public int maxValue(int array[]){
  int max = Arrays.stream(array).max().getAsInt();
  return max;
}

Now the following line should work.

System.out.println("The highest maximum for the December is: " + maxValue(decMax)); 

I was trying to solve the same with a list of objects and was having issues because I was trying to repack the list of groups into the original list. So I came up with looping through the groups to repack the original List with items that have duplicates.

public List<MediaFileInfo> GetDuplicatePictures()
{
    List<MediaFileInfo> dupes = new List<MediaFileInfo>();
    var grpDupes = from f in _fileRepo
                   group f by f.Length into grps
                   where grps.Count() >1
                   select grps;
    foreach (var item in grpDupes)
    {
        foreach (var thing in item)
        {
            dupes.Add(thing);
        }
    }
    return dupes;
}

After getting the help from @Blender, @ekhumoro and @Dan, I understand the Linux and Python more than before. Thank you. I got the an idea by @ekhumoro, it is I didn't install PyQt5 correctly. So I delete PyQt5 folder and download again. And redo everything from very start.

After redoing, I got the error as my last update at my question. So, when I search at stack, I got the following solution from here

sudo ln -s /usr/include/python2.7 /usr/local/include/python2.7

And then, I did "sudo make" and "sudo make install" step by step. After "sudo make install", I got the following error. But I ignored it and I created a simple design with qt designer. And I converted it into python file by pyuic5. Everything are going well.

install -m 755 -p /home/thura/PyQt/pyuic5 /usr/bin/
strip /usr/bin/pyuic5
strip:/usr/bin/pyuic5: File format not recognized
make: [install_pyuic5] Error 1 (ignored)

I know this was an old answer, but i would like to share my simple solution.

When a number as a decimal it is usually a float in Python.

If you want to remove the decimal and keep it an integer (int). You can call the int() method on it like so...

>>> int(2.0)
2

However, int rounds down so...

>>> int(2.9)
2

If you want to round to the nearest integer you can use round:

>>> round(2.9)
3.0
>>> round(2.4)
2.0

And then call int() on that:

>>> int(round(2.9))
3
>>> int(round(2.4))
2

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

Demo: http://jsfiddle.net/ThinkingStiff/89Enq/

HTML:

<a id="music" href="Music.html">Music I Like</a>

CSS:

#music {
    background-color: black;
    color: white;
    display: block;
    height: 40px;
    line-height: 40px;
    text-decoration: none;
    width: 100px;
    text-align: center;
}

Output:

Just another suggestion, removing any trailing white-space

limitStrLength = (text, max_length) => {
    if(text.length > max_length - 3){
        return text.substring(0, max_length).trimEnd() + "..."
    }
    else{
        return text
    }

also happens when you use jinja templates (which have different syntax for calling object methods) and you forget to set it in settings.py

sudo apt-get install python-dev  # for python2.x installs
sudo apt-get install python3-dev  # for python3.x installs

It will install any missing headers. It solved my issue

I suggest you use a HiddenField inside template field use FindControl to find this field.

ie:

ASPX

                <asp:TemplateField>
                    <ItemTemplate>
                        <asp:HiddenField ID="hfFname" runat="server" Value='<%# Eval("FileName") %>' />
                    </ItemTemplate>
                </asp:TemplateField>

Code behind

protected void gvAttachments_RowDeleting(object sender, GridViewDeleteEventArgs e)
    {
        GridView gv1 = (GridView)sender;
        GridViewRow gvr1 = (GridViewRow)gv1.Rows[e.RowIndex];

        //get hidden field value and not directly from the GridviewRow, as that will be null or empty!
        HiddenField hf1 = (HiddenField)gvr1.FindControl("hfFname");
        if (hf1 != null)
        {
           ..
        }
    }

Or you could do this:

inside_git_repo="$(git rev-parse --is-inside-work-tree 2>/dev/null)"

if [ "$inside_git_repo" ]; then
  echo "inside git repo"
else
  echo "not in git repo"
fi

if (!myString.replace(/^\s+|\s+$/g,""))
  alert('string is only whitespace');

For your case, add the following code to vscode's settings.json.

"python.linting.pylintArgs": [
    "--init-hook='import sys; sys.path.append(\"~/google-cloud-sdk/platform/google_appengine/lib\")'"
]

For the other who got troubles with pip packages, you can go with

"python.linting.pylintArgs": [
    "--init-hook='import sys; sys.path.append(\"/usr/local/lib/python3.7/dist-packages\")'"
]

You should replace python3.7 above with your python version.

You can't mix tab and spaces for identation. Best practice is to convert all tabs to spaces.

How to fix this? Well just delete all the spaces/tabs before each line and convert them uniformly either to tabs OR spaces, but don't mix. Best solution: enable in your Editor the option to convert automagically any tabs to spaces.

Also be aware that your actual problem may lie in the lines before this block, and python throws the error here, because of a leading invalid indentation which doesn't match the following identations!

Evaluating "1,2,3" results in (1, 2, 3), a tuple. As you've discovered, tuples are immutable. Convert to a list before processing.

$('div').css({
    position: 'relative',
    top: '-15px'
});

Use slicing and is to check for the last element:

for data in data_list:
    <code_that_is_done_for_every_element>
    if not data is data_list[-1]:
        <code_that_is_done_between_elements>

Caveat emptor: This only works if all elements in the list are actually different (have different locations in memory). Under the hood, Python may detect equal elements and reuse the same objects for them. For instance, for strings of the same value and common integers.

var fs = require('fs');

function base64Encode(file) {
    var body = fs.readFileSync(file);
    return body.toString('base64');
}


var base64String = base64Encode('test.jpg');
console.log(base64String);

Its only possible to get the WSDL if the webservice is configured to deliver it. Therefor you have to specify a serviceBehavior and enable httpGetEnabled:

<serviceBehaviors>
    <behavior name="BindingBehavior">
        <serviceMetadata httpGetEnabled="true" />
        <serviceDebug includeExceptionDetailInFaults="true" />
    </behavior>
</serviceBehaviors>

In case the webservice is only accessible via https you have to enable httpsGetEnabled instead of httpGetEnabled.

Not only are you reading the whole of each file into memory, but also you laboriously replicate the information in a table called list_of_lines.

You have a secondary problem: your choices of variable names severely obfuscate what you are doing.

Here is your script rewritten with the readlines() caper removed and with meaningful names:

file_A1_B1 = open("A1_B1_100000.txt", "r")
file_A2_B2 = open("A2_B2_100000.txt", "r")
file_A1_B2 = open("A1_B2_100000.txt", "r")
file_A2_B1 = open("A2_B1_100000.txt", "r")
file_write = open ("average_generations.txt", "w")

for afile in files:
    table = []
    for aline in afile:
        values = aline.split('\t')
        values.remove('\n') # why?
        table.append(values)
    row_count = len(table)
    row0length = len(table[0])
    print_counter = 4
    for column_index in range(row0length):
        column_total = 0
        for row_index in range(row_count):
            number = float(table[row_index][column_index])
            column_total = column_total + number
        column_average = column_total/row_count
        print column_average
        if print_counter == 4:
            file_write.write(str(column_average)+'\n')
            print_counter = 0
        print_counter +=1
file_write.write('\n')

It rapidly becomes apparent that (1) you are calculating column averages (2) the obfuscation led some others to think you were calculating row averages.

As you are calculating column averages, no output is required until the end of each file, and the amount of extra memory actually required is proportional to the number of columns.

Here is a revised version of the outer loop code:

for afile in files:
    for row_count, aline in enumerate(afile, start=1):
        values = aline.split('\t')
        values.remove('\n') # why?
        fvalues = map(float, values)
        if row_count == 1:
            row0length = len(fvalues)
            column_index_range = range(row0length)
            column_totals = fvalues
        else:
            assert len(fvalues) == row0length
            for column_index in column_index_range:
                column_totals[column_index] += fvalues[column_index]
    print_counter = 4
    for column_index in column_index_range:
        column_average = column_totals[column_index] / row_count
        print column_average
        if print_counter == 4:
            file_write.write(str(column_average)+'\n')
            print_counter = 0
        print_counter +=1

Edit: After updating to appcompat-v7:22.1.1 and using AppCompatActivity instead of ActionBarActivity my styles.xml looks like:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Note: This means I am using a Toolbar provided by the framework (NOT included in an XML file).

This worked for me:
styles.xml file:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowActionBar">false</item>
    <item name="theme">@style/ThemeOverlay.AppCompat.Dark.ActionBar</item>
</style>

Update: A quote from Gabriele Mariotti's blog.

With the new Toolbar you can apply a style and a theme. They are different! The style is local to the Toolbar view, for example the background color. The app:theme is instead global to all ui elements inflated in the Toolbar, for example the color of the title and icons.

This worked for me in my template:

{{ request.scheme }}://{{ request.META.HTTP_HOST }}{% url 'equipos:marca_filter' %}

I needed the full url to pass it to a js fetch function. I hope this help you.

How about using the ExecutorService.shutDownNow() method as described in http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/ExecutorService.html? It seems to be the simplest solution.

The easiest way to explain P v. NP and such without getting into technicalities is to compare "word problems" with "multiple choice problems".

When you are trying to solve a "word problem" you have to find the solution from scratch. When you are trying to solve a "multiple choice problems" you have a choice: either solve it as you would a "word problem", or try to plug in each of the answers given to you, and pick the candidate answer that fits.

It often happens that a "multiple choice problem" is much easier than the corresponding "word problem": substituting the candidate answers and checking whether they fit may require significantly less effort than finding the right answer from scratch.

Now, if we would agree the effort that takes polynomial time "easy" then the class P would consist of "easy word problems", and the class NP would consist of "easy multiple choice problems".

The essence of P v. NP is the question: "Are there any easy multiple choice problems that are not easy as word problems"? That is, are there problems for which it's easy to verify the validity of a given answer but finding that answer from scratch is difficult?

Now that we understand intuitively what NP is, we have to challenge our intuition. It turns out that there are "multiple choice problems" that, in some sense, are hardest of them all: if one would find a solution to one of those "hardest of them all" problems one would be able to find a solution to ALL NP problems! When Cook discovered this 40 years ago it came as a complete surprise. These "hardest of them all" problems are known as NP-hard. If you find a "word problem solution" to one of them you would automatically find a "word problem solution" to each and every "easy multiple choice problem"!

Finally, NP-complete problems are those that are simultaneously NP and NP-hard. Following our analogy, they are simultaneously "easy as multiple choice problems" and "the hardest of them all as word problems".

For the Android library projects, I do it as in the attached screenshot:

Right click the project, select Properties->Android and in the library section click Add. From here you can select the available libraries.

If you are importing a jar file, then importing them as jar or external jar, as other posters posted would work. I prefer to copy/paste jar file in the libs folder (create one if it doesn't exist) and then import as jar.

you can try like this:

var request = require('request');
request.post({ headers: {'content-type' : 'application/json'}
               , url: <your URL>, body: <req_body in json> }
               , function(error, response, body){
   console.log(body); 
}); 

There are 2 main ways:

1. Using .content (simplest/official) (see Zhenyi Zhang's answer):

   import io  # Note: io.BytesIO is StringIO.StringIO on Python2.
   import requests
   
   r = requests.get('http://lorempixel.com/400/200')
   r.raise_for_status()
   with io.BytesIO(r.content) as f:
       with Image.open(f) as img:
           img.show()
   

2. Using .raw (see Martijn Pieters's answer):

   import requests
   
   r = requests.get('http://lorempixel.com/400/200', stream=True)
   r.raise_for_status()
   r.raw.decode_content = True  # Required to decompress gzip/deflate compressed responses.
   with PIL.Image.open(r.raw) as img:
       img.show()
   r.close()  # Safety when stream=True ensure the connection is released.
   

Timing both shows no noticeable difference.

Just to add on Jukka K. Korpela answer above, font awesome already defined a css selector "fa". You can simply do <i class="fa">&#xf015;</i> . The catch here is, fa defines the font-style:normal, if you need italic, you can override like <i class="fa" style="font-style:italic">&#xf015;</i>

The above answers get at the most fundamental aspects of the C++ memory model. In practice, most uses of std::atomic<> "just work", at least until the programmer over-optimizes (e.g., by trying to relax too many things).

There is one place where mistakes are still common: sequence locks. There is an excellent and easy-to-read discussion of the challenges at https://www.hpl.hp.com/techreports/2012/HPL-2012-68.pdf. Sequence locks are appealing because the reader avoids writing to the lock word. The following code is based on Figure 1 of the above technical report, and it highlights the challenges when implementing sequence locks in C++:

atomic<uint64_t> seq; // seqlock representation
int data1, data2;     // this data will be protected by seq

T reader() {
    int r1, r2;
    unsigned seq0, seq1;
    while (true) {
        seq0 = seq;
        r1 = data1; // INCORRECT! Data Race!
        r2 = data2; // INCORRECT!
        seq1 = seq;

        // if the lock didn't change while I was reading, and
        // the lock wasn't held while I was reading, then my
        // reads should be valid
        if (seq0 == seq1 && !(seq0 & 1))
            break;
    }
    use(r1, r2);
}

void writer(int new_data1, int new_data2) {
    unsigned seq0 = seq;
    while (true) {
        if ((!(seq0 & 1)) && seq.compare_exchange_weak(seq0, seq0 + 1))
            break; // atomically moving the lock from even to odd is an acquire
    }
    data1 = new_data1;
    data2 = new_data2;
    seq = seq0 + 2; // release the lock by increasing its value to even
}

As unintuitive as it seams at first, data1 and data2 need to be atomic<>. If they are not atomic, then they could be read (in reader()) at the exact same time as they are written (in writer()). According to the C++ memory model, this is a race even if reader() never actually uses the data. In addition, if they are not atomic, then the compiler can cache the first read of each value in a register. Obviously you wouldn't want that... you want to re-read in each iteration of the while loop in reader().

It is also not sufficient to make them atomic<> and access them with memory_order_relaxed. The reason for this is that the reads of seq (in reader()) only have acquire semantics. In simple terms, if X and Y are memory accesses, X precedes Y, X is not an acquire or release, and Y is an acquire, then the compiler can reorder Y before X. If Y was the second read of seq, and X was a read of data, such a reordering would break the lock implementation.

The paper gives a few solutions. The one with the best performance today is probably the one that uses an atomic_thread_fence with memory_order_relaxed before the second read of the seqlock. In the paper, it's Figure 6. I'm not reproducing the code here, because anyone who has read this far really ought to read the paper. It is more precise and complete than this post.

The last issue is that it might be unnatural to make the data variables atomic. If you can't in your code, then you need to be very careful, because casting from non-atomic to atomic is only legal for primitive types. C++20 is supposed to add atomic_ref<>, which will make this problem easier to resolve.

To summarize: even if you think you understand the C++ memory model, you should be very careful before rolling your own sequence locks.

You can add any extension (in Wamp and Xampp servers) by removing the semi-colon (;)

You can simply use named constructors for creating different types of buttons with icons. For instance

FlatButton.icon(onPressed: null, icon: null, label: null);
RaisedButton.icon(onPressed: null, icon: null, label: null);

But if you have specfic requirements then you can always create custom button with different layouts or simply wrap a widget in GestureDetector.

The problem is that you have a circular import: in app.py

from mod_login import mod_login

in mod_login.py

from app import app

This is not permitted in Python. See Circular import dependency in Python for more info. In short, the solution are

• either gather everything in one big file
• delay one of the import using local import

As other answers pointed out, it is most likely generated by some tool.

But if I were the original author of the file, my answer would be: Consistency.

If I am not allowed to put double quotes in my attributes, why put them in the element's content ? Why do these specs always have these exceptional cases .. If I had to write the HTML spec, I would say All double quotes need to be encoded. Done.

Today it is like In attribute values we need to encode double quotes, except when the attribute value itself is defined by single quotes. In the content of elements, double quotes can be, but are not required to be, encoded. (And I am surely forgetting some cases here).

Double quotes are a keyword of the spec, encode them. Lesser/greater than are a keyword of the spec, encode them. etc..

If you are using BaseFragment for your app then you can add onBackPressedDispatcher to your base fragment.

//Make a BaseFragment for all your fragments
abstract class BaseFragment : Fragment() {

private lateinit var callback: OnBackPressedCallback

/**
 * SetBackButtonDispatcher in OnCreate
 */

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setBackButtonDispatcher()
}

/**
 * Adding BackButtonDispatcher callback to activity
 */
private fun setBackButtonDispatcher() {
    callback = object : OnBackPressedCallback(true) {
        override fun handleOnBackPressed() {
            onBackPressed()
        }
    }
    requireActivity().onBackPressedDispatcher.addCallback(this, callback)
}

/**
 * Override this method into your fragment to handleBackButton
 */
  open fun onBackPressed() {
  }

}

Override onBackPressed() in your fragment by extending basefragment

//How to use this into your fragment
class MyFragment() : BaseFragment(){

private lateinit var mView: View

override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
    mView = inflater.inflate(R.layout.fragment_my, container, false)
    return mView.rootView
}

override fun onBackPressed() {
    //Write your code here on back pressed.
}

}

For pyautogui users:

import pyautogui
screenshot = pyautogui.screenshot()

I found a purely Javascript solution here that seems to work for major browsers for both PC and Mac. I tested it in BrowserStack for both platforms and it works like a dream. The Javascript solution posted in this thread by Jason D'Souza is really nice because it gives you a lot of information about the browser, but it has an issue identifying Edge which seems to look like Chrome to it. His code could probably be modified a bit with this solution to make it work for Edge too. Here is the snippet of code I found:

    var browser = (function (agent) {
    switch (true) {
        case agent.indexOf("edge") > -1: return "edge";
        case agent.indexOf("edg") > -1: return "chromium based edge (dev or canary)";
        case agent.indexOf("opr") > -1 && !!window.opr: return "opera";
        case agent.indexOf("chrome") > -1 && !!window.chrome: return "chrome";
        case agent.indexOf("trident") > -1: return "ie";
        case agent.indexOf("firefox") > -1: return "firefox";
        case agent.indexOf("safari") > -1: return "safari";
        default: return "other";
    }
})(window.navigator.userAgent.toLowerCase());
console.log(window.navigator.userAgent.toLowerCase() + "\n" + browser);

I had a similar problem and solved it using list...not sure if this will help or not

classes = list(unique_labels(y_true, y_pred))

In Visual Studio 2015 (this still holds in 2019 for the same value), check the setting:

Tools > Options > Environment > Documents > Check for consistent line endings on load

VS2015 will now prompt you to convert line endings when you open a file where they are inconsistent, so all you need to do is open the files, select the desired option from the prompt and save them again.

Display the value of my_key in an ini-style my_file:

sed -n -e 's/^\s*my_key\s*=\s*//p' my_file

• -n -- do not print anything by default
• -e -- execute the expression
• s/PATTERN//p -- display anything following this pattern In the pattern:
• ^ -- pattern begins at the beginning of the line
• \s -- whitespace character
• * -- zero or many (whitespace characters)

Example:

$ cat my_file
# Example INI file
something   = foo
my_key      = bar
not_my_key  = baz
my_key_2    = bing

$ sed -n -e 's/^\s*my_key\s*=\s*//p' my_file
bar

So:

Find a pattern where the line begins with zero or many whitespace characters, followed by the string my_key, followed by zero or many whitespace characters, an equal sign, then zero or many whitespace characters again. Display the rest of the content on that line following that pattern.

Kotlin code snippet for your android app

Step:1 Write down code in On create Method

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
    setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true)
}
if (Build.VERSION.SDK_INT >= 19) {
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
}
if (Build.VERSION.SDK_INT >= 21) {
    setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false)
    window.statusBarColor = Color.TRANSPARENT
}

Step2: You Need SetWindowFlag method which describe in Below code.

private fun setWindowFlag(bits: Int, on: Boolean) {
    val win = window
    val winParams = win.attributes
    if (on) {
        winParams.flags = winParams.flags or bits
    } else {
        winParams.flags = winParams.flags and bits.inv()
    }
    win.attributes = winParams
}

Java code snippet for your android app:

Step1: Main Activity Code

if (Build.VERSION.SDK_INT >= 19 && Build.VERSION.SDK_INT < 21) {
    setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true);
}
if (Build.VERSION.SDK_INT >= 19) {
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
}

if (Build.VERSION.SDK_INT >= 21) {
    setWindowFlag(this, WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false);
    getWindow().setStatusBarColor(Color.TRANSPARENT);
}

Step2: SetWindowFlag Method

public static void setWindowFlag(Activity activity, final int bits, boolean on) {
    Window win = activity.getWindow();
    WindowManager.LayoutParams winParams = win.getAttributes();
    if (on) {
        winParams.flags |= bits;
    } else {
        winParams.flags &= ~bits;
    }
    win.setAttributes(winParams);
}

The other one doesn't work. According to the docs this is the way you should do it.

angular.module('plunker', ['ui.bootstrap']);
var ModalDemoCtrl = function ($scope, $modal) {

    var modalInstance = $modal.open({
      templateUrl: 'myModalContent.html',
      controller: ModalInstanceCtrl,
      resolve: {
        test: function () {
          return 'test variable';
        }
      }
    });
};

var ModalInstanceCtrl = function ($scope, $modalInstance, test) {

  $scope.test = test;
};

See plunkr

For JavaScript use this function:

function disableselect(e) {return false}
document.onselectstart = new Function (return false)
document.onmousedown = disableselect

to enable the selection use this:

function reEnable() {return true}

and use this function anywhere you want:

document.onclick = reEnable

Try this I learned this from @nmaier when I was mucking around with converting to ico: Well i dont really understand what array buffer is but it does what we need:

function previewFile(file) {

  var reader  = new FileReader();

  reader.onloadend = function () {
    console.log(reader.result); //this is an ArrayBuffer
  }
  reader.readAsArrayBuffer(file);
}

notice how i just changed your readAsDataURL to readAsArrayBuffer.

Here is the example @nmaier gave me: https://stackoverflow.com/a/24253997/1828637

it has a fiddle

if you want to take this and make a file out of it i would think you would use file-output-stream in the onloadend
