Programs & Examples On #Updatepanel

You can use the UpdateProgress control:

Also see: ajax "loading" icon with UpdatePanel postbacks

You need to use ScriptManager.RegisterStartupScript for Ajax.

protected void ButtonPP_Click(object sender, EventArgs e) {     if (radioBtnACO.SelectedIndex < 0)     {         string csname1 = "PopupScript";          var cstext1 = new StringBuilder();         cstext1.Append("alert('Please Select Criteria!')");          ScriptManager.RegisterStartupScript(this, GetType(), csname1,             cstext1.ToString(), true);     } } 

You can't call _doPostBack() because it forces submition of the form. Why don't you disable the PostBack on the UpdatePanel?

Read these tutorials Asp.net Update Panel and Introduction to the UpdatePanel Control

Simple and understandable

I try many things and finally found that the last parameter must be false and you must add <SCRIPT> tag to the java script :

string script = "< SCRIPT >alert('hello!');< /SCRIPT>";

ScriptManager.RegisterClientScriptBlock(Page, Page.GetType(), key, script, **false**);

Put into the Button-Control the Attribute "UseSubmitBehavior=false".

You can use tf.pack (tf.stack in TensorFlow 1.0.0) method for this purpose. Here is how to pack a random image of type numpy.ndarray into a Tensor:

import numpy as np
import tensorflow as tf
random_image = np.random.randint(0,256, (300,400,3))
random_image_tensor = tf.pack(random_image)
tf.InteractiveSession()
evaluated_tensor = random_image_tensor.eval()

UPDATE: to convert a Python object to a Tensor you can use tf.convert_to_tensor function.

I call a scheduled script who must connect to a list of Server this way:

Powershell.exe -File "YourScriptPath" "Par1,Par2,Par3"

Then inside the script:

param($list_of_servers)
...
Connect-Viserver $list_of_servers.split(",")

The split operator returns an array of string

I had similar problem. I had a time series of daily sales for 10 different stores and 50 different items. I needed to split the original dataframe in 500 dataframes (10stores*50stores) to apply Machine Learning models to each of them and I couldn't do it manually.

This is the head of the dataframe:

I have created two lists; one for the names of dataframes and one for the couple of array [item_number, store_number].

    list=[]
    for i in range(1,len(items)*len(stores)+1):
    global list
    list.append('df'+str(i))

    list_couple_s_i =[]
    for item in items:
          for store in stores:
                  global list_couple_s_i
                  list_couple_s_i.append([item,store])

And once the two lists are ready you can loop on them to create the dataframes you want:

         for name, it_st in zip(list,list_couple_s_i):
                   globals()[name] = df.where((df['item']==it_st[0]) & 
                                                (df['store']==(it_st[1])))
                   globals()[name].dropna(inplace=True)

In this way I have created 500 dataframes.

Hope this will be helpful!

I just put this in my .gitconfig aliases section and love how it works:

pub = "!f() { git push -u ${1:-origin} `git symbolic-ref HEAD`; }; f"

Will push the current branch to origin with git pub or another repo with git pub repo-name. Tasty.

&& and || are what is called "short circuiting". That means that they will not evaluate the second operand if the first operand is enough to determine the value of the expression.

For example if the first operand to && is false then there is no point in evaluating the second operand, since it can't change the value of the expression (false && true and false && false are both false). The same goes for || when the first operand is true.

You can read more about this here: http://en.wikipedia.org/wiki/Short-circuit_evaluation From the table on that page you can see that && is equivalent to AndAlso in VB.NET, which I assume you are referring to.

Hello what about something like this? Very simple implementation, Injector itself is singleton and also added classes into it. Of course can be extended very easily. If you are looking for something more sophisticated check this package: https://pub.dartlang.org/packages/flutter_simple_dependency_injection

void main() {  
  Injector injector = Injector();
  injector.add(() => Person('Filip'));
  injector.add(() => City('New York'));

  Person person =  injector.get<Person>(); 
  City city =  injector.get<City>();

  print(person.name);
  print(city.name);
}

class Person {
  String name;

  Person(this.name);
}

class City {
  String name;

  City(this.name);
}


typedef T CreateInstanceFn<T>();

class Injector {
  static final Injector _singleton =  Injector._internal();
  final _factories = Map<String, dynamic>();

  factory Injector() {
    return _singleton;
  }

  Injector._internal();

  String _generateKey<T>(T type) {
    return '${type.toString()}_instance';
  }

  void add<T>(CreateInstanceFn<T> createInstance) {
    final typeKey = _generateKey(T);
    _factories[typeKey] = createInstance();
  }

  T get<T>() {
    final typeKey = _generateKey(T);
    T instance = _factories[typeKey];
    if (instance == null) {
      print('Cannot find instance for type $typeKey');
    }

    return instance;
  }
}

You can't use float inside flex container and the reason is that float property does not apply to flex-level boxes as you can see here Fiddle.

So if you want to position child element to right of parent element you can use margin-left: auto but now child element will also push other div to the right as you can see here Fiddle.

What you can do now is change order of elements and set order: 2 on child element so it doesn't affect second div

.parent {_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  margin-left: auto;_x000D_
  order: 2;_x000D_
}

<div class="parent">_x000D_
  <div class="child">Ignore parent?</div>_x000D_
  <div>another child</div>_x000D_
</div>

I have the same problem with Yandex Maps server, JDK 1.6 and Apache HttpClient 4.2.1. The error was

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

with enabled debug by -Djavax.net.debug=all there was a message in a log

Could not generate DH keypair

I have fixed this problem by adding BouncyCastle library bcprov-jdk16-1.46.jar and registering a provider in a map service class

public class MapService {

    static {
        Security.addProvider(new BouncyCastleProvider());
    }

    public GeocodeResult geocode() {

    }

}

A provider is registered at the first usage of MapService.

Most likely the reason your push did not work is order of execution.

use is a compile time directive. You push is done at execution time:

push ( @INC,"directory_path/more_path");
use Foo.pm;  # In directory path/more_path

You can use a BEGIN block to get around this problem:

BEGIN {
    push ( @INC,"directory_path/more_path");
}
use Foo.pm;  # In directory path/more_path

IMO, it's clearest, and therefore best to use lib:

use lib "directory_path/more_path";
use Foo.pm;  # In directory path/more_path

See perlmod for information about BEGIN and other special blocks and when they execute.

Edit

For loading code relative to your script/library, I strongly endorse File::FindLib

You can say use File::FindLib 'my/test/libs'; to look for a library directory anywhere above your script in the path.

Say your work is structured like this:

   /home/me/projects/
    |- shared/
    |   |- bin/
    |   `- lib/
    `- ossum-thing/
       `- scripts 
           |- bin/
           `- lib/

Inside a script in ossum-thing/scripts/bin:

use File::FindLib 'lib/';
use File::FindLib 'shared/lib/';

Will find your library directories and add them to your @INC.

It's also useful to create a module that contains all the environment set-up needed to run your suite of tools and just load it in all the executables in your project.

use File::FindLib 'lib/MyEnvironment.pm'

<?php 
    $sessionDetails = $this->Session->read('Auth.User');

    if (!empty($sessionDetails)) {


        $loginFlag = 1;
        # code...
    }else{
        $loginFlag =  0;
    }


?>

<script type="text/javascript">

    var sessionValue = '<?php echo $loginFlag; ?>';
    if (sessionValue = 0) {

        //model show
    }
</script>

I wrapped mp3 decoder library and made it available for .net developers. You can find it here:

http://sourceforge.net/projects/mpg123net/

Included are the samples to convert mp3 file to PCM, and read ID3 tags.

append returns None, so at the second iteration you are calling method append of NoneType. Just remove the assignment:

for i in range(0, n):
    list1.append([i])

As the instructions state on the iTuneconnect Developer Guidelines you need to ensure that you are the "team agent" to delete apps. This is stated in the quote below from the developer guidelines.

If the Delete App button isn’t displayed, check that you’re the team agent and that the app is in one of the statuses that allow the app to be deleted.

I have just checked on my account by logging in as the main account holder and the delete button is there for an app that I have previously removed from sale but when I have looked in as another user they don't have this permission, only the main account holder seems to have it.

If you get 'Access violation at address 00000000.', you are calling a function pointer that hasn't been assigned - possibly an event handler or a callback function.

for example

type
TTest = class(TForm);
protected
  procedure DoCustomEvent;
public
  property OnCustomEvent : TNotifyEvent read FOnCustomEvent  write FOnCustomEvent;
end;

procedure TTest.DoCustomEvent;
begin
  FOnCustomEvent(Self);  
end;

Instead of

procedure TTest.DoCustomEvent;
begin
  if Assigned(FOnCustomEvent) then // need to check event handler is assigned!
    FOnCustomEvent(Self);  
end;

If the error is in a third party component, and you can track the offending code down, use an empty event handler to prevent the AV.

If you just want to skip binary files, I suggest you look at the -I (upper case i) option. It ignores binary files. I regularly use the following command:

grep -rI --exclude-dir="\.svn" "pattern" *

It searches recursively, ignores binary files, and doesn't look inside Subversion hidden folders, for whatever pattern I want. I have it aliased as "grepsvn" on my box at work.

If I want the sort to be applied to only one of the UNION if use Union all:

Select id,name,age
From Student
Where age < 15
Union all
Select id,name,age
From 
(
Select id,name,age
From Student
Where Name like "%a%"
Order by name
)

You must check the String length. You assume that you can do substring(0,38) as long as String is not null, but you actually need the String to be of at least 38 characters length.

I had this issue... It was the log that was huge. Logs are here :

/var/lib/docker/containers/<container id>/<container id>-json.log

You can manage this in the run command line or in the compose file. See there : Configure logging drivers

I personally added these 3 lines to my docker-compose.yml file :

my_container:
  logging:
    options:
      max-size: 10m

A couple of answers that should work above but this is how i would write it.

Also, i wouldn't declare controllers inside templates. It's better to declare them on your routes imo.

add-text.tpl.html

<div ng-controller="myController">
    <form ng-submit="addText(myText)">
        <input type="text" placeholder="Let's Go" ng-model="myText">
        <button type="submit">Add</button>
    </form>
    <ul>
        <li ng-repeat="text in arrayText">{{ text }}</li>
    </ul>
</div>

app.js

(function() {

    function myController($scope) {
        $scope.arrayText = ['hello', 'world'];
        $scope.addText = function(myText) {
             $scope.arrayText.push(myText);     
        };
    }

    angular.module('app', [])
        .controller('myController', myController);

})();

Not sure if this is faster, but at least it's shorter :)

int rows = new DataView(dtFoo, "IsActive = 'Y'", "IsActive",
    DataViewRowState.CurrentRows).Table.Rows.Count;

Autoplay works only with /v/ instead of /embed/, so change the src to:

src="//www.youtube.com/v/qUJYqhKZrwA?autoplay=1&showinfo=0&controls=0"

When you imported the WSDL, you should have an ObjectFactory class which should have bunch of methods for creating various input parameters.

ObjectFactory factory = new ObjectFactory();
JAXBElement<String> createMessageDescription = factory.createMessageDescription("description");
message.setDescription(createMessageDescription);

Modify the compiler setting file of the project in the following path and change the 'target' to 1.7:

/project/.idea/compiler.xml

<bytecodeTargetLevel>
  <module name="project-name" target="1.7" />
</bytecodeTargetLevel>

Two ways to implement a Caesar Cipher:

Option 1: Change chars to ASCII numbers, then you can increase the value, then revert it back to the new character.

Option 2: Use a Map map each letter to a digit like this.

A - 0
B - 1
C - 2
etc...

With a map you don't have to re-calculate the shift every time. Then you can change to and from plaintext to encrypted by following map.

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

This works for me, hacked it once to see if it is possible, but never actually used in my program (GUI is so much nicer):

import time
f = '%4i %%'
len_to_clear = len(f)+1
clear = '\x08'* len_to_clear
print 'Progress in percent:'+' '*(len_to_clear),
for i in range(123):
    print clear+f % (i*100//123),
    time.sleep(0.4)
raw_input('\nDone')

os.path.dirname is what you are looking for -

os.path.dirname(r"C:\folder1\folder2\filename.xml")

Make sure you prepend r to the string so that its considered as a raw string.

Demo -

In [46]: os.path.dirname(r"C:\folder1\folder2\filename.xml")
Out[46]: 'C:\\folder1\\folder2'

If you just want folder2 , you can use os.path.basename with the above, Example -

os.path.basename(os.path.dirname(r"C:\folder1\folder2\filename.xml"))

Demo -

In [48]: os.path.basename(os.path.dirname(r"C:\folder1\folder2\filename.xml"))
Out[48]: 'folder2'

I also met this problem while using Xshell to connect Linux server.

After seaching for methods, I find Xming + Xshell to solve image imshow problem with matplotlib.

If solutions aboved can't solve your problem, just try to download Xming under the condition you're using Xshell. Then set the attribute in Xshell, SSH->tunnel->X11transfer->choose X DISPLAY localhost:0.0

Heres a truly "Reversible Dictionary", Based upon Adam Acosta's solution, but enforcing val-to-key calls to be unique and easily return key from value:

from collections import UserDict


class ReversibleDict(UserDict):
    def __init__(self, enforce_unique=True, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.val_to_keys = {}
        self.check_val = self.check_unique if enforce_unique else lambda x: x

    def __setitem__(self, key, value):
        self.check_val(value)
        super().__setitem__(key, value)
        self.val_to_keys[value] = key

    def __call__(self, value):
        return self.val_to_keys[value]

    def check_unique(self, value):
        assert value not in self.val_to_keys, f"Non unique value '{value}'"
        return value

If you want to enforce uniqueness on dictionary values ensure to set enforce_unique=True. to get keys from values just do rev_dict(value), to call values from keys just do as usual dict['key'], here's an example of usage:

rev_dict = ReversibleDict(enforce_unique=True)
rev_dict["a"] = 1
rev_dict["b"] = 2
rev_dict["c"] = 3
print("full dictinoary is: ", rev_dict)
print("value for key 'b' is: ", rev_dict["b"])
print("key for value '2' is: ", rev_dict(2))
print("tring to set another key with the same value results in error: ")
rev_dict["d"] = 1

Change the frame size of viewcontroller.view.frame, and then add to subview. [viewcontrollerparent.view addSubview:viewcontroller.view]

More simpler single query oracle version.

WITH data 
     AS (SELECT granted_role

If the user should select only one option at once, just remove the "multiple" - make a normal select:

  <select name="mySelect" size="3">
     <option>Foo</option>
     <option>Bar</option>
     <option>Foo Bar</option>
     <option>Bar Foo</option>
  </select>

Fiddle

Using json, you can subclass JSONEncoder and override the default() method to provide your own custom serializers:

import json
import datetime

class DateTimeJSONEncoder(json.JSONEncoder):
    def default(self, obj):
        if isinstance(obj, datetime.datetime):
            return obj.isoformat()
        else:
            return super(DateTimeJSONEncoder, self).default(obj)

Then, you can call it like this:

>>> DateTimeJSONEncoder().encode([datetime.datetime.now()])
'["2010-06-15T14:42:28"]'

You can do this with a data URL. This includes the entire document in a single string of HTML. For example, the following HTML:

<html><body>foo</body></html>

can be encoded as this:

data:text/html;charset=utf-8,%3Chtml%3E%3Cbody%3Efoo%3C/body%3E%3C/html%3E

and then set as the src attribute of the iframe. Example.

Edit: The other alternative is to do this with Javascript. This is almost certainly the technique I'd choose. You can't guarantee how long a data URL the browser will accept. The Javascript technique would look something like this:

var iframe = document.getElementById('foo'),
    iframedoc = iframe.contentDocument || iframe.contentWindow.document;

iframedoc.body.innerHTML = 'Hello world';

Example

Edit 2 (December 2017): use the Html5's srcdoc attribute, just like in Saurabh Chandra Patel's answer, who now should be the accepted answer! If you can detect IE/Edge efficiently, a tip is to use srcdoc-polyfill library only for them and the "pure" srcdoc attribute in all non-IE/Edge browsers (check caniuse.com to be sure).

<iframe srcdoc="<html><body>Hello, <b>world</b>.</body></html>"></iframe>

This happens because $cOTLdata is not null but the index 'char_data' does not exist. Previous versions of PHP may have been less strict on such mistakes and silently swallowed the error / notice while 7.4 does not do this anymore.

To check whether the index exists or not you can use isset():

isset($cOTLdata['char_data'])

Which means the line should look something like this:

$len = isset($cOTLdata['char_data']) ? count($cOTLdata['char_data']) : 0;

Note I switched the then and else cases of the ternary operator since === null is essentially what isset already does (but in the positive case).

You can observe the relation between features either by drawing a heat map from seaborn or scatter matrix from pandas.

Scatter Matrix:

pd.scatter_matrix(dataframe, alpha = 0.3, figsize = (14,8), diagonal = 'kde');

If you want to visualize each feature's skewness as well - use seaborn pairplots.

sns.pairplot(dataframe)

Sns Heatmap:

import seaborn as sns

f, ax = pl.subplots(figsize=(10, 8))
corr = dataframe.corr()
sns.heatmap(corr, mask=np.zeros_like(corr, dtype=np.bool), cmap=sns.diverging_palette(220, 10, as_cmap=True),
            square=True, ax=ax)

The output will be a correlation map of the features. i.e. see the below example.

The correlation between grocery and detergents is high. Similarly:

1. Grocery and Detergents.

1. Milk and Grocery
2. Milk and Detergents_Paper

1. Milk and Deli
2. Frozen and Fresh.
3. Frozen and Deli.

From Pairplots: You can observe same set of relations from pairplots or scatter matrix. But from these we can say that whether the data is normally distributed or not.

Note: The above is same graph taken from the data, which is used to draw heatmap.

You need to escape the . because it has the meaning of "an arbitrary character" in a regular expression.

mystring = mystring.replace(/\./g,' ')

This warning means that two projects reference the same assembly (e.g. System.Windows.Forms) but the two projects require different versions. You have a few options:

1. Recompile all projects to use the same versions (e.g. move all to .Net 3.5). This is the preferred option because all code is running with the versions of dependencies they were compiled with.

2. Add a binding redirect. This will suppress the warning. However, your .Net 2.0 projects will (at runtime) be bound to the .Net 3.5 versions of dependent assemblies such as System.Windows.Forms. You can quickly add a binding redirect by double-clicking on error in Visual Studio.

3. Use CopyLocal=true. I'm not sure if this will suppress the warning. It will, like option 2 above, mean that all projects will use the .Net 3.5 version of System.Windows.Forms.

Here are a couple of ways to identify the offending reference(s):

• You can use a utility such as the one found at https://gist.github.com/1553265
• Another simple method is to set Build output verbosity (Tools, Options, Projects and Solutions, Build and Run, MSBuild project build output verbosity, Detailed) and after building, search the output window for the warning, and look at the text just above it. (Hat tip to pauloya who suggested this in the comments on this answer).

Many answers here advocate adding a timestamp to the URL. Unless you are modifying your production files directly, the file's timestamp is not likely to reflect the time when a file was changed. In most cases this will cause the URL to change more frequently than the file itself. This is why you should use a fast hash of the file's contents such as MD5 as levik and others have suggested.

Keep in mind that the value should be calculated once at build or run, rather than each time the file is requested.

As an example, here's a simple bash script that reads a list of filenames from standard input and writes a JSON file containing hashes to standard output:

#!/bin/bash
# Create a JSON map from filenames to MD5 hashes
# Run as hashes.sh < inputfile.list > outputfile.json

echo "{"
delim=""
while read l; do
    echo "$delim\"$l\": \"`md5 -q $l`\""
    delim=","
done
echo "}"

This file could then be loaded at server startup and referenced instead of reading the file system.

You should have to use DateTime.TryParseExact.

var newDate = DateTime.ParseExact("20111120", 
                                  "yyyyMMdd", 
                                   CultureInfo.InvariantCulture);

OR

string str = "20111021";
string[] format = {"yyyyMMdd"};
DateTime date;

if (DateTime.TryParseExact(str, 
                           format, 
                           System.Globalization.CultureInfo.InvariantCulture,
                           System.Globalization.DateTimeStyles.None, 
                           out date))
{
     //valid
}

You don't say what shell you are using, but they generally don't support regular expressions that way, although there are common *nix CLI tools (grep, sed, etc) that do.

What shells like bash do support is globbing, which uses some similiar characters (eg, *) but is not the same thing.

Newer versions of bash do have a regular expression operator, =~:

for x in `ls`; do 
    if [[ $x =~ .+\..* ]]; then 
        echo $x; 
    fi; 
done

How about:

public static T Min<T>(params T[] values)
{
    if (values == null) throw new ArgumentNullException("values");
    var comparer = Comparer<T>.Default;
    switch(values.Length) {
        case 0: throw new ArgumentException();
        case 1: return values[0];
        case 2: return comparer.Compare(values[0],values[1]) < 0
               ? values[0] : values[1];
        default:
            T best = values[0];
            for (int i = 1; i < values.Length; i++)
            {
                if (comparer.Compare(values[i], best) < 0)
                {
                    best = values[i];
                }
            }
            return best;
    }        
}
// overload for the common "2" case...
public static T Min<T>(T x, T y)
{
    return Comparer<T>.Default.Compare(x, y) < 0 ? x : y;
}

Works with any type that supports IComparable<T> or IComparable.

Actually, with LINQ, another alternative is:

var min = new[] {x,y,z}.Min();

If you are behind a proxy. Android Studio will add proxy for http to Gradle, but will not for https. Add proxy settings for https to gradle.properties

Following on from Tomasz's answer, you can also programmatically set the shade of the entire button using the PorterDuff multiply mode. This will change the button colour rather than just the tint.

If you start with a standard grey shaded button:

button.getBackground().setColorFilter(0xFFFF0000, PorterDuff.Mode.MULTIPLY);

will give you a red shaded button,

button.getBackground().setColorFilter(0xFF00FF00, PorterDuff.Mode.MULTIPLY);

will give you a green shaded button etc., where the first value is the colour in hex format.

It works by multiplying the current button colour value by your colour value. I'm sure there's also a lot more you can do with these modes.

Let's assume two dates:

NSDate *date1;
NSDate *date2;

Then the following comparison will tell which is earlier/later/same:

if ([date1 compare:date2] == NSOrderedDescending) {
    NSLog(@"date1 is later than date2");
} else if ([date1 compare:date2] == NSOrderedAscending) {
    NSLog(@"date1 is earlier than date2");
} else {
    NSLog(@"dates are the same");
}

Please refer to the NSDate class documentation for more details.

Consider Android Development:

IDE: Eclipse etc..

Library: android.app.Activity library (Class with all code)

API: Interface basically all functions with which we call

SDK: The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android (----tools - DDMS,Emulator ----platforms - Android OS versions, ----platform-tools - ADB, ----API docs)

ToolKit: Could be ADT Bundle

Framework: Big library but more of architecture-oriented

How about:

import re

s = "alpha.Customer[cus_Y4o9qMEZAugtnW] ..."
m = re.search(r"\[([A-Za-z0-9_]+)\]", s)
print m.group(1)

For me this prints:

cus_Y4o9qMEZAugtnW

Note that the call to re.search(...) finds the first match to the regular expression, so it doesn't find the [card] unless you repeat the search a second time.

Edit: The regular expression here is a python raw string literal, which basically means the backslashes are not treated as special characters and are passed through to the re.search() method unchanged. The parts of the regular expression are:

1. \[ matches a literal [ character
2. ( begins a new group
3. [A-Za-z0-9_] is a character set matching any letter (capital or lower case), digit or underscore
4. + matches the preceding element (the character set) one or more times.
5. ) ends the group
6. \] matches a literal ] character

Edit: As D K has pointed out, the regular expression could be simplified to:

m = re.search(r"\[(\w+)\]", s)

since the \w is a special sequence which means the same thing as [a-zA-Z0-9_] depending on the re.LOCALE and re.UNICODE settings.

private void usuarioBox_TextChanged(object sender, EventArgs e)
{
    string textComboBox = usuarioBox.Text;
}

I changed color programmatically in this way :

var builder = new AlertDialog.Builder (this);
...
...
...
var dialog = builder.Show ();
int textColorId = Resources.GetIdentifier ("alertTitle", "id", "android");
TextView textColor = dialog.FindViewById<TextView> (textColorId);
textColor?.SetTextColor (Color.DarkRed);

as alertTitle, you can change other data by this way (next example is for titleDivider):

int titleDividerId = Resources.GetIdentifier ("titleDivider", "id", "android");
View titleDivider = dialog.FindViewById (titleDividerId);
titleDivider?.SetBackgroundColor (Color.Red);

this is in C#, but in java it is the same.

Just so my fellow neuronically impaired comrades might chance upon it here, I had assumed that, for web projects, if the linked file was an external .config file that the "output directory" would be the same directory that web.config lives in, i.e. your web project's root. In retrospect, it is entirely unsurprising that it copies the linked file into the root/bin folder.

So, if it's an appSettings include file, your web.config's open tag would be

<appSettings file=".\bin\includedAppSettingsFile.config">

Duh.

If you are using the two formulas at the same time, it will not work... Here is a simple spreadsheet with it working: https://docs.google.com/spreadsheet/ccc?key=0AiOy0YDBXjt4dDJSQWg1Qlp6TEw5SzNqZENGOWgwbGc If you are still getting problems I would need to know what type of erroneous result you are getting.

Today() returns a numeric integer value: Returns the current computer system date. The value is updated when your document recalculates. TODAY is a function without arguments.

I face this issue multiple times. It turns out, that it has nothing to do with permissions, cache, etc. The error message is misleading. For node v 6.x you will see more detailed error stack but not after 7.x For me and my colleges, the issue is timeout function. Basically the package install has not finished yet (i.e. holding the directory) when npm tries to delete it. in node 6.x you can see that in finalize.js now it's gone! Just use yarn.

• To remove white spaces:

1) To remove white space everywhere:

df.columns = df.columns.str.replace(' ', '')

2) To remove white space at the beginning of string:

df.columns = df.columns.str.lstrip()

3) To remove white space at the end of string:

df.columns = df.columns.str.rstrip()

4) To remove white space at both ends:

df.columns = df.columns.str.strip()

• To replace white spaces with other characters (underscore for instance):

5) To replace white space everywhere

df.columns = df.columns.str.replace(' ', '_')

6) To replace white space at the beginning:

df.columns = df.columns.str.replace('^ +', '_')

7) To replace white space at the end:

df.columns = df.columns.str.replace(' +$', '_')

8) To replace white space at both ends:

df.columns = df.columns.str.replace('^ +| +$', '_')

All above applies to a specific column as well, assume you have a column named col, then just do:

df[col] = df[col].str.strip()  # or .replace as above

if you use WAMP you should also add the certificate line in php.ini for Apache (besides the default php.ini file):

[curl]
curl.cainfo = C:\your_location\cacert.pem

works for php5.3+

Here is my two cents:

final           String CENT_1 = new Random().nextInt(2) == 0 ? "HEADS" : "TAILS";
final   static  String CENT_2 = new Random().nextInt(2) == 0 ? "HEADS" : "TAILS";

Example:

package test;

public class Test {

    final long OBJECT_ID = new Random().nextLong();
    final static long CLASSS_ID = new Random().nextLong();

    public static void main(String[] args) {
        Test[] test = new Test[5];
        for (int i = 0; i < test.length; i++){
            test[i] = new Test();
            System.out.println("Class id: "+test[i].CLASSS_ID);//<- Always the same value
            System.out.println("Object id: "+test[i].OBJECT_ID);//<- Always different
        }
    }
}

The key is that variables and functions can return different values.Therefore final variables can be assigned with different values.

There is definitly a problem with the destination folder path.

Your above error message says, it wants to put the contents to a file in the directory /files/grantapps/, which would be beyond your vhost, but somewhere in the system (see the leading absolute slash )

You should double check:

• Is the directory /home/username/public_html/files/grantapps/ really present.
• Contains your loop and your file_put_contents-Statement the absolute path /home/username/public_html/files/grantapps/

If you decide to add a .pch file manually and you want to use Objective-C just like before xCode 6 you will also have to import UIKit and Foundation frameworks in the .pch file. Otherwise you will have to import these frameworks manually in each header file. You can add the following code anyway as it tests for the language used:

#ifdef __OBJC__
    #import <UIKit/UIKit.h>
    #import <Foundation/Foundation.h>
#endif

I'm using the J.S. to fix a sidebar menu. I've tried a lot of solutions with CSS but it's the simplest way to solve it, just add J.S. adding and removing a native BootStrap class: "position-fixed".

The J.S.:

var lateral = false;
function fixar() {

            var element, name, arr;
            element = document.getElementById("minhasidebar");

            if (lateral) {
                element.className = element.className.replace(
                        /\bposition-fixed\b/g, "");
                lateral = false;
            } else {

                name = "position-fixed";
                arr = element.className.split(" ");
                if (arr.indexOf(name) == -1) {
                    element.className += " " + name;
                }
                lateral = true;
            }

        }

The HTML:

Sidebar:

<aside>
        <nav class="sidebar ">
             <div id="minhasidebar">
                 <ul class="nav nav-pills">

I have added slashes before inserting into database so on the time of fetching i removed slashes again stripslashes() and it works for me. I am sharing the code which works for me.

How i inserted into mysql db (blob type)

$db = mysqli_connect("localhost","root","","dName"); 
$image = addslashes(file_get_contents($_FILES['images']['tmp_name']));
$query = "INSERT INTO student_img (id,image) VALUES('','$image')";  
$query = mysqli_query($db, $query);

Now to access the image

$sqlQuery = "SELECT * FROM student_img WHERE id = $stid";
$rs = $db->query($sqlQuery);
$result=mysqli_fetch_array($rs);
echo '<img src="data:image/jpeg;base64,'.base64_encode( stripslashes($result['image']) ).'"/>';

Hope it will help someone

Thanks.

use this

<div ng-class="{states}[condition]"></div>

for example if the condition is [2 == 2], states are {true: '...', false: '...'}

<div ng-class="{true: 'ClassA', false: 'ClassB'}[condition]"></div>

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

For those looking for a Swift version of @amro's answer:

        // update the flag indicator
        userDefaults.setBool(true, forKey: "hasRunBefore")
        userDefaults.synchronize() // forces the app to update the NSUserDefaults

        return

1. Parse the JSON

const arr = JSON.parse(json);

2. For each object in the JSON, rename the key:

obj.id = obj._id;
delete obj._id;

3. Stringify the result

All together:

function renameKey ( obj, oldKey, newKey ) {
  obj[newKey] = obj[oldKey];
  delete obj[oldKey];
}

const json = `

Pandas timestamp differences returns a datetime.timedelta object. This can easily be converted into hours by using the *as_type* method, like so

import pandas
df = pandas.DataFrame(columns=['to','fr','ans'])
df.to = [pandas.Timestamp('2014-01-24 13:03:12.050000'), pandas.Timestamp('2014-01-27 11:57:18.240000'), pandas.Timestamp('2014-01-23 10:07:47.660000')]
df.fr = [pandas.Timestamp('2014-01-26 23:41:21.870000'), pandas.Timestamp('2014-01-27 15:38:22.540000'), pandas.Timestamp('2014-01-23 18:50:41.420000')]
(df.fr-df.to).astype('timedelta64[h]')

to yield,

0    58
1     3
2     8
dtype: float64

EDIT: (As per the comments in question:)

I've been looking into this since then. I was lucky enough that I had repo laying around. Still it's not clear to me whether you need to enclose your commands between single quotes by force. I looked into the repo syntax and I don't think you need to. You could used double quotes around your command, and then use whatever single and double quotes you need inside provided you escape double ones.

I like this method (it looks a little cleaner):

text = text.replace(new RegExp("cat","g"), "dog"); 

Perhaps your question is in this sense:

If you want to use: $python myscript.py

You don't need that line at all. The system will call python and then python interpreter will run your script.

But if you intend to use: $./myscript.py

Calling it directly like a normal program or bash script, you need write that line to specify to the system which program use to run it, (and also make it executable with chmod 755)

Considering your previous example:

inventory file:

[db]
10.112.83.37

group_vars/all

data_base_url=jdbc:oracle:thin:@{{ db }}:1521/ssdenwdb

template file:

oracle_url = {{ data_base_url }}

You might want to replace your group_vars/all with

data_base_url="jdbc:oracle:thin:@{{ groups['db'][0] }}:1521/ssdenwdb"

Coming from JavaScript, this was something I was used to having "built-in" via Array.prototype.splice(), so I made a Python function that does the same:

def list_splice(target, start, delete_count=None, *items):
    """Remove existing elements and/or add new elements to a list.

    target        the target list (will be changed)
    start         index of starting position
    delete_count  number of items to remove (default: len(target) - start)
    *items        items to insert at start index

    Returns a new list of removed items (or an empty list)
    """
    if delete_count == None:
        delete_count = len(target) - start

    # store removed range in a separate list and replace with *items
    total = start + delete_count
    removed = target[start:total]
    target[start:total] = items

    return removed

There isn't a system feature to change the height of the table based upon the contents of the tableview. Having said that, it is possible to programmatically change the height of the tableview based upon the contents, specifically based upon the contentSize of the tableview (which is easier than manually calculating the height yourself). A few of the particulars vary depending upon whether you're using the new autolayout that's part of iOS 6, or not.

But assuming you're configuring your table view's underlying model in viewDidLoad, if you want to then adjust the height of the tableview, you can do this in viewDidAppear:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    [self adjustHeightOfTableview];
}

Likewise, if you ever perform a reloadData (or otherwise add or remove rows) for a tableview, you'd want to make sure that you also manually call adjustHeightOfTableView there, too, e.g.:

- (IBAction)onPressButton:(id)sender
{
    [self buildModel];
    [self.tableView reloadData];

    [self adjustHeightOfTableview];
}

So the question is what should our adjustHeightOfTableview do. Unfortunately, this is a function of whether you use the iOS 6 autolayout or not. You can determine if you have autolayout turned on by opening your storyboard or NIB and go to the "File Inspector" (e.g. press option+command+1 or click on that first tab on the panel on the right):

Let's assume for a second that autolayout was off. In that case, it's quite simple and adjustHeightOfTableview would just adjust the frame of the tableview:

- (void)adjustHeightOfTableview
{
    CGFloat height = self.tableView.contentSize.height;
    CGFloat maxHeight = self.tableView.superview.frame.size.height - self.tableView.frame.origin.y;

    // if the height of the content is greater than the maxHeight of
    // total space on the screen, limit the height to the size of the
    // superview.

    if (height > maxHeight)
        height = maxHeight;

    // now set the frame accordingly

    [UIView animateWithDuration:0.25 animations:^{
        CGRect frame = self.tableView.frame;
        frame.size.height = height;
        self.tableView.frame = frame;

        // if you have other controls that should be resized/moved to accommodate
        // the resized tableview, do that here, too
    }];
}

If your autolayout was on, though, adjustHeightOfTableview would adjust a height constraint for your tableview:

- (void)adjustHeightOfTableview
{
    CGFloat height = self.tableView.contentSize.height;
    CGFloat maxHeight = self.tableView.superview.frame.size.height - self.tableView.frame.origin.y;

    // if the height of the content is greater than the maxHeight of
    // total space on the screen, limit the height to the size of the
    // superview.

    if (height > maxHeight)
        height = maxHeight;

    // now set the height constraint accordingly

    [UIView animateWithDuration:0.25 animations:^{
        self.tableViewHeightConstraint.constant = height;
        [self.view setNeedsUpdateConstraints];
    }];
}

For this latter constraint-based solution to work with autolayout, we must take care of a few things first:

1. Make sure your tableview has a height constraint by clicking on the center button in the group of buttons here and then choose to add the height constraint:

   

2. Then add an IBOutlet for that constraint:

   

3. Make sure you adjust other constraints so they don't conflict if you adjust the size tableview programmatically. In my example, the tableview had a trailing space constraint that locked it to the bottom of the screen, so I had to adjust that constraint so that rather than being locked at a particular size, it could be greater or equal to a value, and with a lower priority, so that the height and top of the tableview would rule the day:

   

   What you do here with other constraints will depend entirely upon what other controls you have on your screen below the tableview. As always, dealing with constraints is a little awkward, but it definitely works, though the specifics in your situation depend entirely upon what else you have on the scene. But hopefully you get the idea. Bottom line, with autolayout, make sure to adjust your other constraints (if any) to be flexible to account for the changing tableview height.

As you can see, it's much easier to programmatically adjust the height of a tableview if you're not using autolayout, but in case you are, I present both alternatives.

Auto-generate one form from another.

Source:

enum {
  VALUE1, /* value 1 */
  VALUE2, /* value 2 */
};

Generated:

const char* enum2str[] = {
  "value 1", /* VALUE1 */
  "value 2", /* VALUE2 */
};

If enum values are large then a generated form could use unordered_map<> or templates as suggested by Constantin.

Source:

enum State{
  state0 = 0, /* state 0 */
  state1 = 1, /* state 1 */
  state2 = 2, /* state 2 */
  state3 = 4, /* state 3 */

  state16 = 0x10000, /* state 16 */
};

Generated:

template <State n> struct enum2str { static const char * const value; };
template <State n> const char * const enum2str<n>::value = "error";

template <> struct enum2str<state0> { static const char * const value; };
const char * const enum2str<state0>::value = "state 0";

Example:

#include <iostream>

int main()
{
  std::cout << enum2str<state16>::value << std::endl;
  return 0;
}

Look at the Doctrine API source-code :

class EntityRepository{
  ...
  public function findAll(){
    return $this->findBy(array());
  }
  ...
}

npm install --save bootstrap

afterwards, inside angular.json (previously .angular-cli.json) inside the project's root folder, find styles and add the bootstrap css file like this:

for angular 6

"styles": [
          "../node_modules/bootstrap/dist/css/bootstrap.min.css",
          "styles.css"
],

for angular 7

"styles": [
          "node_modules/bootstrap/dist/css/bootstrap.min.css",
          "src/styles.css"
],

A useful application for : is if you're only interested in using parameter expansions for their side-effects rather than actually passing their result to a command. In that case you use the PE as an argument to either : or false depending upon whether you want an exit status of 0 or 1. An example might be : "${var:=$1}". Since : is a builtin it should be pretty fast.

If anyone else stuck on same point, following solved my problem.

If you can add in a '.' (dot) character at the end of each line, this seems to prevent Outlook ruining text formatting.

For all users on a specific database, do the following:

# psql
\c your_database
select grantee, table_catalog, privilege_type, table_schema, table_name from information_schema.table_privileges order by grantee, table_schema, table_name;

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

If you use the following instead:

$json = file_get_contents($url);
$data = json_decode($json, TRUE);

The TRUE returns an array instead of an object.

If you prefer a graphical user interface, you can use pgAdmin III (Linux/Windows/OS X). Simply right click on the table of your choice, then "backup". It will create a pg_dump command for you.

I cannot solve it with source ./myscript.sh. It says the source not found error.
Failed also when using . ./myscript.sh. It gives can't open myscript.sh.

So my option is put it in a text file to be called in the next script.

#!/bin/sh
echo "Perform Operation in su mode"
echo "ARCH=arm" >> environment.txt
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export "CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?" >> environment.txt
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...

Tnen call it whenever is needed:

while read -r line; do
    line=$(sed -e 's/[[:space:]]*$//' <<<${line})
    var=`echo $line | cut -d '=' -f1`; test=$(echo $var)
    if [ -z "$(test)" ];then eval export "$line";fi
done <environment.txt

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

This is a solution. Later you can split by ":" and take the values of the array

 /**
 * Converts milliseconds to human readeable language separated by ":"
 * Example: 190980000 --> 2:05:3 --> 2days 5hours 3min
 */
function dhm(t){
    var cd = 24 * 60 * 60 * 1000,
        ch = 60 * 60 * 1000,
        d = Math.floor(t / cd),
        h = '0' + Math.floor( (t - d * cd) / ch),
        m = '0' + Math.round( (t - d * cd - h * ch) / 60000);
    return [d, h.substr(-2), m.substr(-2)].join(':');
}

//Example
var delay = 190980000;                   
var fullTime = dhm(delay);
console.log(fullTime);

Below solution is a shorthand for @Andy Wilkinson's solution, except that it doesn't have to use a separate class or on a @Bean annotated method.

application.yml:

input:
  name: raja
  age: 12
  somedata:
    abcd: 1 
    bcbd: 2
    cdbd: 3

SomeComponent.java:

@Component
@EnableConfigurationProperties
@ConfigurationProperties(prefix = "input")
class SomeComponent {

    @Value("${input.name}")
    private String name;

    @Value("${input.age}")
    private Integer age;

    private HashMap<String, Integer> somedata;

    public HashMap<String, Integer> getSomedata() {
        return somedata;
    }

    public void setSomedata(HashMap<String, Integer> somedata) {
        this.somedata = somedata;
    }

}

We can club both @Value annotation and @ConfigurationProperties, no issues. But getters and setters are important and @EnableConfigurationProperties is must to have the @ConfigurationProperties to work.

I tried this idea from groovy solution provided by @Szymon Stepniak, thought it will be useful for someone.

When you can not assume that column b comes before c you can use match to find the column number of both, min to get the lower column number and seq_len to get a sequence until this column. Then you can use this index first as a positive subset, than place the new column d and then use the sequence again as a negative subset.

i <- seq_len(min(match(c("b", "c"), colnames(x))))
data.frame(x[i], d, x[-i])
#cbind(x[i], d, x[-i]) #Alternative
#  a b  d c
#1 1 4 10 7
#2 2 5 11 8
#3 3 6 12 9

In case you know that column b comes before c you can place the new column d after b:

i <- seq_len(match("b", colnames(x)))
data.frame(x[i], d, x[-i])
#  a b  d c
#1 1 4 10 7
#2 2 5 11 8
#3 3 6 12 9

Data:

x <- data.frame(a = 1:3, b = 4:6, c = 7:9)
d <- 10:12

Most likely, the problem is that you're using a relative file path to open the file, but the current working directory isn't set to what you think it is.

It's a common misconception that relative paths are relative to the location of the python script, but this is untrue. Relative file paths are always relative to the current working directory, and the current working directory doesn't have to be the location of your python script.

You have three options:

• Use an absolute path to open the file:

  file = open(r'C:\path\to\your\file.yaml')
  

• Generate the path to the file relative to your python script:

  from pathlib import Path
  
  script_location = Path(__file__).absolute().parent
  file_location = script_location / 'file.yaml'
  file = file_location.open()
  

  (See also: How do I get the path and name of the file that is currently executing?)

• Change the current working directory before opening the file:

  import os
  
  os.chdir(r'C:\path\to\your\file')
  file = open('file.yaml')
  

Other common mistakes that could cause a "file not found" error include:

• Accidentally using escape sequences in a file path:

  path = 'C:\Users\newton\file.yaml'
  # Incorrect! The '\n' in 'Users\newton' is a line break character!
  

  To avoid making this mistake, remember to use raw string literals for file paths:

  path = r'C:\Users\newton\file.yaml'
  # Correct!
  

  (See also: Windows path in Python)

• Forgetting that Windows doesn't display file extensions:

  Since Windows doesn't display known file extensions, sometimes when you think your file is named file.yaml, it's actually named file.yaml.yaml. Double-check your file's extension.

What you're doing is fine, but if you feel the need to 'Java-it-up' you could use a Transformer and the collect method from Apache Commons, e.g.:

public class IntegerToStringTransformer implements Transformer<Integer, String> {
   public String transform(final Integer i) {
      return (i == null ? null : i.toString());
   }
}

..and then..

CollectionUtils.collect(
   collectionOfIntegers, 
   new IntegerToStringTransformer(), 
   newCollectionOfStrings);

Make sure you image is a relative path such as:

@Url.Content("~/Content/images/myimage.png")

MVC4

<img src="~/Content/images/myimage.png" />

You could convert the byte[] into a Base64 string on the fly.

string base64String = Convert.ToBase64String(imageBytes);

<img src="@String.Format("data:image/png;base64,{0}", base64string)" />

What I have done with no memory leaks or lint warnings is to use @f.trajkovski's method, but instead of using MainActivity, use WeakReference<MainActivity> instead.

public class MainActivity extends AppCompatActivity {
public static WeakReference<MainActivity> weakActivity;
// etc..
 public static MainActivity getmInstanceActivity() {
    return weakActivity.get();
}
}

Then in MainActivity OnCreate()

weakActivity = new WeakReference<>(MainActivity.this);

Then in another class

MainActivity.getmInstanceActivity().yourMethod();

Works like a charm

This is detailed with a reasonable amount of detail by Guido himself in his blog post Method Resolution Order (including two earlier attempts).

In your example, Third() will call First.__init__. Python looks for each attribute in the class's parents as they are listed left to right. In this case, we are looking for __init__. So, if you define

class Third(First, Second):
    ...

Python will start by looking at First, and, if First doesn't have the attribute, then it will look at Second.

This situation becomes more complex when inheritance starts crossing paths (for example if First inherited from Second). Read the link above for more details, but, in a nutshell, Python will try to maintain the order in which each class appears on the inheritance list, starting with the child class itself.

So, for instance, if you had:

class First(object):
    def __init__(self):
        print "first"

class Second(First):
    def __init__(self):
        print "second"

class Third(First):
    def __init__(self):
        print "third"

class Fourth(Second, Third):
    def __init__(self):
        super(Fourth, self).__init__()
        print "that's it"

the MRO would be [Fourth, Second, Third, First].

By the way: if Python cannot find a coherent method resolution order, it'll raise an exception, instead of falling back to behavior which might surprise the user.

Edited to add an example of an ambiguous MRO:

class First(object):
    def __init__(self):
        print "first"

class Second(First):
    def __init__(self):
        print "second"

class Third(First, Second):
    def __init__(self):
        print "third"

Should Third's MRO be [First, Second] or [Second, First]? There's no obvious expectation, and Python will raise an error:

TypeError: Error when calling the metaclass bases
    Cannot create a consistent method resolution order (MRO) for bases Second, First

Edit: I see several people arguing that the examples above lack super() calls, so let me explain: The point of the examples is to show how the MRO is constructed. They are not intended to print "first\nsecond\third" or whatever. You can – and should, of course, play around with the example, add super() calls, see what happens, and gain a deeper understanding of Python's inheritance model. But my goal here is to keep it simple and show how the MRO is built. And it is built as I explained:

>>> Fourth.__mro__
(<class '__main__.Fourth'>,
 <class '__main__.Second'>, <class '__main__.Third'>,
 <class '__main__.First'>,
 <type 'object'>)

class() function is the equivalent of typeof()

You can also use isa() to check if a variable is of a particular type. If you want to be even more specific, you can use ischar(), isfloat(), iscell(), etc.

var ids = [];

    $(document).ready(function($) {    
    $(".color_cell").bind('click', function() {
        alert('Test');

        ids.push(this.id);       
    });
});

app.config

<client>
    <endpoint address="" binding="basicHttpBinding" 
    bindingConfiguration="LisansSoap" 
    contract="Lisans.LisansSoap" 
    name="LisansSoap" />
</client>

program

 Lisans.LisansSoapClient test = new LisansSoapClient("LisansSoap",
                         "http://webservis.uzmanevi.com/Lisans/Lisans.asmx");

 MessageBox.Show(test.LisansKontrol("","",""));

You can also use the cell property.

Cells(1, 1).Value = "Hey, what's up?"

Make sure to use a . before Cells(1,1).Value as in .Cells(1,1).Value, if you are using it within With function. If you are selecting some sheet.

I had the same problem. I was using Docker Toolbox on Windows Home. Instead of localhost I had to use http://192.168.99.100:8080/.

You can get the correct IP address using the command:

docker-machine ip

The above command returned 192.168.99.100 for me.

To loop through an object array or just array in javascript, you can do the following:

var cars = [{name: 'Audi'}, {name: 'BMW'}, {name: 'Ferrari'}, {name: 'Mercedes'}, {name: 'Maserati'}];

for(var i = 0; i < cars.length; i++) {
    console.log(cars[i].name);
}

There is also the forEach() function, which is more "javascript-ish" and also less code but more complicated for its syntax:

cars.forEach(function (car) {
    console.log(car.name);
});

And both of them are outputting the following:

// Audi
// BMW
// Ferrari
// Mercedes
// Maserati

The easiest way is to use the 'plumbing' command update-ref to delete the current branch.

You can't use git branch -D as it has a safety valve to stop you deleting the current branch.

This puts you back into the 'initial commit' state where you can start with a fresh initial commit.

git update-ref -d refs/heads/master
git commit -m "New initial commit"

The error is from this:

def playSound(myList):
  for i in range(myList): # <= myList is a list, not an integer

You cannot pass a list to range which expects an integer. Most likely, you meant to do:

 def playSound(myList):
  for list_item in myList:

OR

 def playSound(myList):
  for i in range(len(myList)):

OR

 def playSound(myList):
  for i, list_item in enumerate(myList):

SELECT * FROM `orders` WHERE `order_date_time`  BETWEEN 1534809600 AND 1536718364

You can just create your own .white class and add it to the glyphicon element.

.white, .white a {
  color: #fff;
}

<i class="glyphicon glyphicon-home white"></i>

There are two things here, and the highest voted answer is technically correct as per the OPs question.

Briefly summarized as:

$("some sort of selector").prop("disabled", true | false);

However should you be using jQuery UI (I know the OP wasn't but some people arriving here might be) then while this will disable the buttons click event it wont make the button appear disabled as per the UI styling.

If you are using a jQuery UI styled button then it should be enabled / disabled via:

$("some sort of selector").button("enable" | "disable");

It works on Amazon AMI on EC2 as well.

The main differenece is that bidirectional relationship provides navigational access in both directions, so that you can access the other side without explicit queries. Also it allows you to apply cascading options to both directions.

Note that navigational access is not always good, especially for "one-to-very-many" and "many-to-very-many" relationships. Imagine a Group that contains thousands of Users:

• How would you access them? With so many Users, you usually need to apply some filtering and/or pagination, so that you need to execute a query anyway (unless you use collection filtering, which looks like a hack for me). Some developers may tend to apply filtering in memory in such cases, which is obviously not good for performance. Note that having such a relationship can encourage this kind of developers to use it without considering performance implications.

• How would you add new Users to the Group? Fortunately, Hibernate looks at the owning side of relationship when persisting it, so you can only set User.group. However, if you want to keep objects in memory consistent, you also need to add User to Group.users. But it would make Hibernate to fetch all elements of Group.users from the database!

So, I can't agree with the recommendation from the Best Practices. You need to design bidirectional relationships carefully, considering use cases (do you need navigational access in both directions?) and possible performance implications.

In my experience the pythonw.exe is faster at least with using pygame.

Match match = Regex.Match(host, "([^.]+\\.[^.]{1,3}(\\.[^.]{1,3})?)$");
string domain = match.Groups[1].Success ? match.Groups[1].Value : null;

host.com => return host.com
s.host.com => return host.com

host.co.uk => return host.co.uk
www.host.co.uk => return host.co.uk
s1.www.host.co.uk => return host.co.uk

A Popen object has a .wait() method exactly defined for this: to wait for the completion of a given subprocess (and, besides, for retuning its exit status).

If you use this method, you'll prevent that the process zombies are lying around for too long.

(Alternatively, you can use subprocess.call() or subprocess.check_call() for calling and waiting. If you don't need IO with the process, that might be enough. But probably this is not an option, because your if the two subprocesses seem to be supposed to run in parallel, which they won't with (check_)call().)

If you have several subprocesses to wait for, you can do

exit_codes = [p.wait() for p in p1, p2]

which returns as soon as all subprocesses have finished. You then have a list of return codes which you maybe can evaluate.

I also use Stefan Petre’s http://www.eyecon.ro/bootstrap-datepicker and it does not work with Bootstrap 3 without modification. Note that http://eternicode.github.io/bootstrap-datepicker/ is a fork of Stefan Petre's code.

You have to change your markup (the sample markup will not work) to use the new CSS and form grid layout in Bootstrap 3. Also, you have to modify some CSS and JavaScript in the actual bootstrap-datepicker implementation.

Here is my solution:

<div class="form-group row">
  <div class="col-xs-8">
    <label class="control-label">My Label</label>
    <div class="input-group date" id="dp3" data-date="12-02-2012" data-date-format="mm-dd-yyyy">
      <input class="form-control" type="text" readonly="" value="12-02-2012">
      <span class="input-group-addon"><i class="glyphicon glyphicon-calendar"></i></span>
    </div>
  </div>
</div>

CSS changes in datepicker.css on lines 176-177:

.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {

Javascript change in datepicker-bootstrap.js on line 34:

this.component = this.element.is('.date') ? this.element.find('.input-group-addon') : false;

UPDATE

Using the newer code from http://eternicode.github.io/bootstrap-datepicker/ the changes are as follows:

CSS changes in datepicker.css on lines 446-447:

.input-group.date .input-group-addon i,
.input-group.date .input-group-addon i {

Javascript change in datepicker-bootstrap.js on line 46:

 this.component = this.element.is('.date') ? this.element.find('.input-group-addon, .btn') : false;

Finally, the JavaScript to enable the datepicker (with some options):

 $(".input-group.date").datepicker({ autoclose: true, todayHighlight: true });

Tested with Bootstrap 3.0 and JQuery 1.9.1. Note that this fork is better to use than the other as it is more feature rich, has localization support and auto-positions the datepicker based on the control position and window size, avoiding the picker going off the screen which was a problem with the older version.

Here is what I used to fade in/out Views, hope this helps someone.

private void crossFadeAnimation(final View fadeInTarget, final View fadeOutTarget, long duration){
    AnimatorSet mAnimationSet = new AnimatorSet();
    ObjectAnimator fadeOut = ObjectAnimator.ofFloat(fadeOutTarget, View.ALPHA,  1f, 0f);
    fadeOut.addListener(new Animator.AnimatorListener() {
        @Override
        public void onAnimationStart(Animator animation) {
        }

        @Override
        public void onAnimationEnd(Animator animation) {
            fadeOutTarget.setVisibility(View.GONE);
        }

        @Override
        public void onAnimationCancel(Animator animation) {
        }

        @Override
        public void onAnimationRepeat(Animator animation) {
        }
    });
    fadeOut.setInterpolator(new LinearInterpolator());

    ObjectAnimator fadeIn = ObjectAnimator.ofFloat(fadeInTarget, View.ALPHA, 0f, 1f);
    fadeIn.addListener(new Animator.AnimatorListener() {
        @Override
        public void onAnimationStart(Animator animation) {
            fadeInTarget.setVisibility(View.VISIBLE);
        }

        @Override
        public void onAnimationEnd(Animator animation) {}

        @Override
        public void onAnimationCancel(Animator animation) {}

        @Override
        public void onAnimationRepeat(Animator animation) {}
    });
    fadeIn.setInterpolator(new LinearInterpolator());
    mAnimationSet.setDuration(duration);
    mAnimationSet.playTogether(fadeOut, fadeIn);
    mAnimationSet.start();
}

I created an online tool to do this. Simply paste any dependency in pom file format, and the dependency tree for that artifact is generated, based on the central maven repository.

In App.config:

<add key="YOURKEY" value="a,b,c"/>

In C#:

string[] InFormOfStringArray = ConfigurationManager.AppSettings["YOURKEY"].Split(',').Select(s => s.Trim()).ToArray();
List<string> list = new List<string>(InFormOfStringArray);

if you tried running java with -version argument, and even though the problem could not be solved by any means, then you might have installed many java versions, like JDK 1.8 and JDK 1.7 at the same time.

So try uninstalling all other versions other than the one you need, then set the JAVA_HOMEpath variable for that JDK remaining, and you're done.

In your case, because of the constraint you need to delete the duplicated records.

1. Find the duplicated rows
2. Organize them by created_at date - in this case I'm keeping the oldest
3. Delete the records with USING to filter the right rows

WITH duplicated AS ( 
    SELECT id,
        count(*) 
    FROM products 
    GROUP BY id 
    HAVING count(*) > 1), 
ordered AS ( 
    SELECT p.id, 
        created_at, 
        rank() OVER (partition BY p.id ORDER BY p.created_at) AS rnk 
    FROM products o 
    JOIN     duplicated d ON d.id = p.id ), 
products_to_delete AS ( 
    SELECT id, 
        created_at 
    FROM   ordered 
    WHERE  rnk = 2
) 
DELETE 
FROM products 
USING products_to_delete 
WHERE products.id = products_to_delete.id 
    AND products.created_at = products_to_delete.created_at;

A major feature of textareas is that they are expandable. On a web page this can result in scroll bars appearing on the text area if the text length overfills the space you set (be that using rows, or be that using CSS. That can be a problem when a user decides to print, particularly with 'printing' to PDF - so set a comfortably large min-height for printed textareas with a conditional CSS rule:

@media print { 
textarea {
min-height: 900px;  
}
}

The dataset in ss.csv contains some columns I am interested in:

ss_ = spark.read.csv("ss.csv", header= True, 
                      inferSchema = True)
ss_.columns

['Reporting Area', 'MMWR Year', 'MMWR Week', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Current week', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Current week, flag', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Previous 52 weeks Med', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Previous 52 weeks Med, flag', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Previous 52 weeks Max', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Previous 52 weeks Max, flag', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Cum 2018', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Cum 2018, flag', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Cum 2017', 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Cum 2017, flag', 'Shiga toxin-producing Escherichia coli, Current week', 'Shiga toxin-producing Escherichia coli, Current week, flag', 'Shiga toxin-producing Escherichia coli, Previous 52 weeks Med', 'Shiga toxin-producing Escherichia coli, Previous 52 weeks Med, flag', 'Shiga toxin-producing Escherichia coli, Previous 52 weeks Max', 'Shiga toxin-producing Escherichia coli, Previous 52 weeks Max, flag', 'Shiga toxin-producing Escherichia coli, Cum 2018', 'Shiga toxin-producing Escherichia coli, Cum 2018, flag', 'Shiga toxin-producing Escherichia coli, Cum 2017', 'Shiga toxin-producing Escherichia coli, Cum 2017, flag', 'Shigellosis, Current week', 'Shigellosis, Current week, flag', 'Shigellosis, Previous 52 weeks Med', 'Shigellosis, Previous 52 weeks Med, flag', 'Shigellosis, Previous 52 weeks Max', 'Shigellosis, Previous 52 weeks Max, flag', 'Shigellosis, Cum 2018', 'Shigellosis, Cum 2018, flag', 'Shigellosis, Cum 2017', 'Shigellosis, Cum 2017, flag']

but I only need a few:

columns_lambda = lambda k: k.endswith(', Current week') or k == 'Reporting Area' or k == 'MMWR Year' or  k == 'MMWR Week'

The filter returns the list of desired columns, list is evaluated:

sss = filter(columns_lambda, ss_.columns)
to_keep = list(sss)

the list of desired columns is unpacked as arguments to dataframe select function that return dataset containing only columns in the list:

dfss = ss_.select(*to_keep)
dfss.columns

The result:

['Reporting Area',
 'MMWR Year',
 'MMWR Week',
 'Salmonellosis (excluding Paratyphoid fever andTyphoid fever)†, Current week',
 'Shiga toxin-producing Escherichia coli, Current week',
 'Shigellosis, Current week']

The df.select() has a complementary pair: http://spark.apache.org/docs/2.4.1/api/python/pyspark.sql.html#pyspark.sql.DataFrame.drop

to drop the list of columns.

The return type must be the same as, or a subtype of, the return type declared in the original overridden method in the superclass.

I just got another case to display backslash \ with Razor and Java Script.

My @Model.AreaName looks like Name1\Name2\Name3 so when I display it all backslashes are gone and I see Name1Name2Name3

I found solution to fix it:

var areafullName =  JSON.parse("@Html.Raw(HttpUtility.JavaScriptStringEncode(JsonConvert.SerializeObject(Model.AreaName)))");

Don't forget to add @using Newtonsoft.Json on top of chtml page.

Folks you can see what the optimizer is doing by running a plan. The generic format of looking into a plan is from the MongoDB documentation . i.e. Cursor.plan(). If you really want to dig deeper you can do a cursor.plan(true) for more details.

Having said that if you have an index, your db.col.find().sort({"field":-1}).limit(1) will read one index entry - even if the index is default ascending and you wanted the max entry and one value from the collection.

In other words the suggestions from @yogesh is correct.

See also question: Can I create a custom classpath on a per application basis in Tomcat

Tomcat 7 Context hold Loader element. According to docs deployment descriptor (what in <Context> tag) can be placed in:

• $CATALINA_BASE/conf/server.xml - bad - require server restarts in order to reread config
• $CATALINA_BASE/conf/context.xml - bad - shared across all applications
• $CATALINA_BASE/work/$APP.war:/META-INF/context.xml - bad - require repackaging in order to change config
• $CATALINA_BASE/work/[enginename]/[hostname]/$APP/META-INF/context.xml - nice, but see last option!!
• $CATALINA_BASE/webapps/$APP/META-INF/context.xml - nice, but see last option!!
• $CATALINA_BASE/conf/[enginename]/[hostname]/$APP.xml - best - completely out of application and automatically scanned for changes!!!

Here my config which demonstrate how to use development version of project files out of $CATALINA_BASE hierarchy (note that I place this file into src/test/resources dir and intruct Maven to preprocess ${basedir} placeholders through pom.xml <filtering>true</filtering> so after build in new environment I copy it to $CATALINA_BASE/conf/Catalina/localhost/$APP.xml):

<Context docBase="${basedir}/src/main/webapp"
         reloadable="true">
    <!-- http://tomcat.apache.org/tomcat-7.0-doc/config/context.html -->
    <Resources className="org.apache.naming.resources.VirtualDirContext"
               extraResourcePaths="/WEB-INF/classes=${basedir}/target/classes,/WEB-INF/lib=${basedir}/target/${project.build.finalName}/WEB-INF/lib"/>
    <Loader className="org.apache.catalina.loader.VirtualWebappLoader"
            virtualClasspath="${basedir}/target/classes;${basedir}/target/${project.build.finalName}/WEB-INF/lib"/>
    <JarScanner scanAllDirectories="true"/>

    <!-- Use development version of JS/CSS files. -->
    <Parameter name="min" value="dev"/>
    <Environment name="app.devel.ldap" value="USER" type="java.lang.String" override="true"/>
    <Environment name="app.devel.permitAll" value="true" type="java.lang.String" override="true"/>
</Context>

UPDATE Tomcat 8 change syntax for <Resources> and <Loader> elements, corresponding part now look like:

<Resources>
    <PostResources className="org.apache.catalina.webresources.DirResourceSet"
                   webAppMount="/WEB-INF/classes" base="${basedir}/target/classes" />
    <PostResources className="org.apache.catalina.webresources.DirResourceSet"
                   webAppMount="/WEB-INF/lib" base="${basedir}/target/${project.build.finalName}/WEB-INF/lib" />
</Resources>

import ast
l = ast.literal_eval('[ "A","B","C" , " D"]')
l = [i.strip() for i in l]

You can put your servers in the default_step group and those vars will apply to it:

# inventory file
[default_step]
prod2
web_v2

Then just move your default_step.yml file to group_vars/default_step.yml.

You can also try this one.

override fun registerWith( registry: PluginRegistry) {
        GeneratedPluginRegistrant.registerWith(registry as FlutterEngine)       
    //registry.registrarFor("io.flutter.plugins.firebasemessaging.FirebaseMessagingPlugin")
    }

I think this one is far better solution than creating a new class.

It is very simple, just add a property:

public string Value {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

Using the Text property is a bit trickier, the UserControl class intentionally hides it. You'll need to override the attributes to put it back in working order:

[Browsable(true), EditorBrowsable(EditorBrowsableState.Always), Bindable(true)]
[DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)]
public override string Text {
  get { return textBox1.Text; }
  set { textBox1.Text = value; }
}

I have come to this post looking for help while using Spring Webflux with Mongo Repository.

My error was similar to owner

Field usersRepository in foobar.UsersService required
a bean of type 'foobar.UsersRepository' that could not be found.

As I was working before with Spring MVC I was surprised by this error.

Because finding help was not so obvious I'm putting answer to this question as it is somehow related and this question is high in search results.

First thing is you must remember about what was mentioned in answer marked as accepted - package hierarchy.

Second important thing is that if you use Webflux you need to use some different package while when using Spring MVC e.g. for MongoDB you need to add

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb-reactive</artifactId>
</dependency>

with -reactive at the end.

The list() function ^[docs] will convert a string into a list of single-character strings.

>>> list('hello')
['h', 'e', 'l', 'l', 'o']

Even without converting them to lists, strings already behave like lists in several ways. For example, you can access individual characters (as single-character strings) using brackets:

>>> s = "hello"
>>> s[1]
'e'
>>> s[4]
'o'

You can also loop over the characters in the string as you can loop over the elements of a list:

>>> for c in 'hello':
...     print c + c,
... 
hh ee ll ll oo

This should work if you need to check keyboard status:

fun Activity.isKeyboardOpened(): Boolean {
    val r = Rect()

    val activityRoot = getActivityRoot()
    val visibleThreshold = dip(UiUtils.KEYBOARD_VISIBLE_THRESHOLD_DP)

    activityRoot.getWindowVisibleDisplayFrame(r)

    val heightDiff = activityRoot.rootView.height - r.height()

    return heightDiff > visibleThreshold;
}

fun Activity.getActivityRoot(): View {
    return (findViewById<ViewGroup>(android.R.id.content)).getChildAt(0);
}

Where UiUtils.KEYBOARD_VISIBLE_THRESHOLD_DP = 100 and dip() is an anko func that convert dpToPx:

fun dip(value: Int): Int {
    return (value * Resources.getSystem().displayMetrics.density).toInt()
}

When you use the IntelliJ IDE, all the project-specific settings for the project are stored under the .idea folder.

Project settings are stored with each specific project as a set of xml files under the .idea folder. If you specify the default project settings, these settings will be automatically used for each newly created project.

Check this documentation for the IDE settings and here is their recommendation on Source Control and an example .gitignore file.

Note: If you are using git or some version control system, you might want to set this folder "ignore". Example - for git, add this directory to .gitignore. This way, the application is not IDE-specific.

I had the same issue. When compared the java version mentioned in the pom.xml file is different and the JAVA_HOME env variable was pointing to different version of jdk.

Have the JAVA_HOME and pom.xml updated to the same jdk installation path

I came here because I had the same problem.
What was the problem for me was that the procedure was defined in the package body, but not in the package header.
I was executing my function with a lose BEGIN END statement.

Selecting camera or gallery for image in Android

I had worked hard on Camera or gallery Image Selection, and created some util class for this work. With the use of these class 'Selecting image camera or gallery is too easy' it just took 5-10 mints of your development.

Step-1: Add these classes in your code.

ImagePickerUtils :- http://www.codesend.com/view/f8f7c637716bf1c693d1490635ed49b3/

BitmapUtils :- http://www.codesend.com/view/81c1c2a3f39f1f7e627f01f67be282cf/

ConvertUriToFilePath :- http://www.codesend.com/view/f4668a29860235dd1b66eb419c5a58b5/

MediaUtils :- https://codeshare.io/5vKEMl

We need to Add these Permission in menifest :

  <uses-permission android:name="android.permission.CAMERA" />
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
  <uses-feature android:name="android.hardware.camera" />
  <uses-feature android:name="android.hardware.camera.autofocus" />

This class function (checkAndRequestPermissions) auto check the permission in Android-Marshmallow and Android - Nougat.

Step-2. Calling camera class for launching camera intent :

 //Create a global veriable .  
     private Uri mCameraUri;
     private static final int CAMERA_REQUEST_CODE = 100;

// Call this function when you wants to select or capture an Image.
       mCameraUri = ImagePickerUtils.createTakePictureIntent(this, CAMERA_REQUEST_CODE);

Step-3: Add onActivityResult in your Activity for receiving data from Intent

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == Activity.RESULT_OK) {
            Uri fileUri = ImagePickerUtils.getFileUriOfImage(this, data, mCameraUri);
            try {
                Bitmap bitmap = null;
                if (CAMERA_REQUEST_CODE == requestCode) {
                    bitmap = new BitmapUtils().getDownsampledBitmap(this, fileUri, imageView.getWidth(), imageView.getHeight());
                }
                if (bitmap != null)
                imageView.setImageBitmap(bitmap);

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

I hope it helps you, If any one having any suggestion to improve these class please add your review in comments.

This is how I did it.

from selenium import webdriver

chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--disable-extensions')

chrome = webdriver.Chrome(chrome_options=chrome_options)

If that suits your needs, I would simply use

Application.ScreenUpdating = False

with the added benefit of accelerating your code, instead of slowing it down by using a second instance of Excel.

here an extended version of the Stefan Farestam's answer:

function parse_yaml {
   local prefix=$2
   local s='[[:space:]]*' w='[a-zA-Z0-9_]*' fs=$(echo @|tr @ '\034')
   sed -ne "s|,$s\]$s\$|]|" \
        -e ":1;s|^\($s\)\($w\)$s:$s\[$s\(.*\)$s,$s\(.*\)$s\]|\1\2: [\3]\n\1  - \4|;t1" \
        -e "s|^\($s\)\($w\)$s:$s\[$s\(.*\)$s\]|\1\2:\n\1  - \3|;p" $1 | \
   sed -ne "s|,$s}$s\$|}|" \
        -e ":1;s|^\($s\)-$s{$s\(.*\)$s,$s\($w\)$s:$s\(.*\)$s}|\1- {\2}\n\1  \3: \4|;t1" \
        -e    "s|^\($s\)-$s{$s\(.*\)$s}|\1-\n\1  \2|;p" | \
   sed -ne "s|^\($s\):|\1|" \
        -e "s|^\($s\)-$s[\"']\(.*\)[\"']$s\$|\1$fs$fs\2|p" \
        -e "s|^\($s\)-$s\(.*\)$s\$|\1$fs$fs\2|p" \
        -e "s|^\($s\)\($w\)$s:$s[\"']\(.*\)[\"']$s\$|\1$fs\2$fs\3|p" \
        -e "s|^\($s\)\($w\)$s:$s\(.*\)$s\$|\1$fs\2$fs\3|p" | \
   awk -F$fs '{
      indent = length($1)/2;
      vname[indent] = $2;
      for (i in vname) {if (i > indent) {delete vname[i]; idx[i]=0}}
      if(length($2)== 0){  vname[indent]= ++idx[indent] };
      if (length($3) > 0) {
         vn=""; for (i=0; i<indent; i++) { vn=(vn)(vname[i])("_")}
         printf("%s%s%s=\"%s\"\n", "'$prefix'",vn, vname[indent], $3);
      }
   }'
}

This version supports the - notation and the short notation for dictionaries and lists. The following input:

global:
  input:
    - "main.c"
    - "main.h"
  flags: [ "-O3", "-fpic" ]
  sample_input:
    -  { property1: value, property2: "value2" }
    -  { property1: "value3", property2: 'value 4' }

produces this output:

global_input_1="main.c"
global_input_2="main.h"
global_flags_1="-O3"
global_flags_2="-fpic"
global_sample_input_1_property1="value"
global_sample_input_1_property2="value2"
global_sample_input_2_property1="value3"
global_sample_input_2_property2="value 4"

as you can see the - items automatically get numbered in order to obtain different variable names for each item. In bash there are no multidimensional arrays, so this is one way to work around. Multiple levels are supported. To work around the problem with trailing white spaces mentioned by @briceburg one should enclose the values in single or double quotes. However, there are still some limitations: Expansion of the dictionaries and lists can produce wrong results when values contain commas. Also, more complex structures like values spanning multiple lines (like ssh-keys) are not (yet) supported.

A few words about the code: The first sed command expands the short form of dictionaries { key: value, ...} to regular and converts them to more simple yaml style. The second sed call does the same for the short notation of lists and converts [ entry, ... ] to an itemized list with the - notation. The third sed call is the original one that handled normal dictionaries, now with the addition to handle lists with - and indentations. The awk part introduces an index for each indentation level and increases it when the variable name is empty (i.e. when processing a list). The current value of the counters are used instead of the empty vname. When going up one level, the counters are zeroed.

Edit: I have created a github repository for this.

Here's a way of doing it using dom4j:

Imports:

import org.dom4j.Document;  
import org.dom4j.DocumentHelper;  
import org.dom4j.io.OutputFormat;  
import org.dom4j.io.XMLWriter;

Code:

String xml = "<your xml='here'/>";  
Document doc = DocumentHelper.parseText(xml);  
StringWriter sw = new StringWriter();  
OutputFormat format = OutputFormat.createPrettyPrint();  
XMLWriter xw = new XMLWriter(sw, format);  
xw.write(doc);  
String result = sw.toString();

You could just make:

<div style="text-align: center; border: 1px solid">_x000D_
  <input type="button" value="button">_x000D_
</div>

Or you could do it like this instead:

<div style="border: 1px solid">_x000D_
  <input type="button" value="button" style="display: block; margin: 0 auto;">_x000D_
</div>

The first one will center align everything inside the div. The other one will center align just the button.

The most recent solution is right. You are reading solutions as a string, in which case the order is 1, then 100, then 104 followed by 2 then 21, then 2001001010, 3 and so forth.

You have to CAST your input as an int instead:

sorted strings:

stringList = (1, 10, 2, 21, 3)

sorted ints:

intList = (1, 2, 3, 10, 21)

To cast, just put the stringList inside int ( blahblah ).

Again:

stringList = (1, 10, 2, 21, 3)

newList = int (stringList)

print newList

=> returns (1, 2, 3, 10, 21) 

After trying few answers they are either not related to my project or , I have tried cleaning and rebuilding (https://stackoverflow.com/a/48760966/8463813). But it didn't work for me directly. I have compared it with older version of code, in which i observed some library files(jars and aars in External Libraries directory) are missing. Tried Invalidate Cache and Restart worked, which created all the libraries and working fine.

Yes, you can use the CSS feature named @font-face. It has only been officially approved in CSS3, but been proposed and implemented in CSS2 and has been supported in IE for quite a long time.

You declare it in the CSS like this:

 @font-face { font-family: Delicious; src: url('Delicious-Roman.otf'); } 
 @font-face { font-family: Delicious; font-weight: bold; src: url('Delicious-Bold.otf');}

Then, you can just reference it like the other standard fonts:

 h3 { font-family: Delicious, sans-serif; }

So, in this case,

<html>
   <head>
    <style>
      @font-face { font-family: JuneBug; src: url('JUNEBUG.TTF'); } 
      h1 {
         font-family: JuneBug
      }
    </style>
   </head>
   <body>
      <h1>Hey, June</h1>
   </body>
</html>

And you just need to put the JUNEBUG.TFF in the same location as the html file.

I downloaded the font from the dafont.com website:

http://www.dafont.com/junebug.font

There is no difference. They both declare "a" to be an integer that cannot be changed.

The place where differences start to appear is when you use pointers.

Both of these:

const int *a
int const *a

declare "a" to be a pointer to an integer that doesn't change. "a" can be assigned to, but "*a" cannot.

int * const a

declares "a" to be a constant pointer to an integer. "*a" can be assigned to, but "a" cannot.

const int * const a

declares "a" to be a constant pointer to a constant integer. Neither "a" nor "*a" can be assigned to.

static int one = 1;

int testfunc3 (const int *a)
{
  *a = 1; /* Error */
  a = &one;
  return *a;
}

int testfunc4 (int * const a)
{
  *a = 1;
  a = &one; /* Error */
  return *a;
}

int testfunc5 (const int * const a)
{
  *a = 1;   /* Error */
  a = &one; /* Error */
  return *a;
}

Check the code below and let me know if it works for you.

<?php if (has_post_thumbnail( $post->ID ) ): ?>
  <?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'single-post-thumbnail' ); ?>
  <div id="custom-bg" style="background-image: url('<?php echo $image[0]; ?>')">

  </div>
<?php endif; ?>

Essentially, use an <a> element with an href attr pointing to the phone number prefixed by tel:. Note that pluses can be used to specify country code, and hyphens can be included simply for human eyes.

MDN Web Docs

https://developer.mozilla.org/en-US/docs/Web/HTML/Element/a#Creating_a_phone_link

The HTML <a> element (or anchor element), along with its href attribute, creates a hyperlink to other web pages, files, locations within the same page, email addresses, or any other URL.

[…]

Offering phone links is helpful for users viewing web documents and laptops connected to phones.

<a href="tel:+491570156">+49 157 0156</a>

IETF Documents

https://tools.ietf.org/html/rfc3966

The tel URI for Telephone Numbers

The "tel" URI has the following syntax:

telephone-uri = "tel:" telephone-subscriber

[…]

Examples

tel:+1-201-555-0123: This URI points to a phone number in the United States. The hyphens are included to make the number more human readable; they separate country, area code and subscriber number.

tel:7042;phone-context=example.com: The URI describes a local phone number valid within the context "example.com".

tel:863-1234;phone-context=+1-914-555: The URI describes a local phone number that is valid within a particular phone prefix.

You can try adding a question mark as below. This worked for me.

 componentWillReceiveProps(nextProps) {
    this.setState({
        title: nextProps?.blog?.title,
        body: nextProps?.blog?.content
     })
    }

The element is supported by all browsers and defines an embedded object within an HTML document.

Bottom line: OBJECT is Good, EMBED is Old. Beside's IE's PARAM tags, any content between OBJECT tags will get rendered if the browser doesn't support OBJECT's referred plugin, and apparently, the content gets http requested regardless if it gets rendered or not. Reference

You should add first jquery.cookie.js then add your js or jQuery where you are using that function.

When browser loads the webpage first it loads this jquery.cookie.js and after then you js or jQuery and now that function is available for use

regex: /^[a-zA-Z0-9_.]$/i

This works

No one has mentioned -m option for remote shutdown:

shutdown -r -f -m \\machinename

Also:

• The -r parameter causes a reboot (which is usually what you want on a remote machine, since physically starting it might be difficult).
• The -f parameter option forces the reboot.
• You must have appropriate privileges to shut down the remote machine, of course.

svn log --verbose -r 42

I was taking a look at the call logs and I noticed that apart from the usual fields in the contents of managedCursor, we have a column "simid" in Dual SIM phones (I checked on Xolo A500s Lite), so as to tag each call in the call log with a SIM. This value is either 1 or 2, most probably denoting SIM1/SIM2.

managedCursor = context.getContentResolver().query(contacts, null, null, null, null);
managedCursor.moveToNext();        
for(int i=0;i<managedCursor.getColumnCount();i++)
{//for dual sim phones
    if(managedCursor.getColumnName(i).toLowerCase().equals("simid"))
        indexSIMID=i;
}

I did not find this column in a single SIM phone (I checked on Xperia L).

So although I don't think this is a foolproof way to check for dual SIM nature, I am posting it here because it could be useful to someone.

For me the answer by Bruno Gomes is the best answer.

But actually, you need not worry about setting the value property of select options. AngularJS will take care of that. Let me explain in detail.

Please consider this fiddle

angular.module('mySettings', []).controller('appSettingsCtrl', function ($scope) {

    $scope.timeFormatTemplates = [{
        label: "Seconds",
        value: 'ss'
    }, {
        label: "Minutes",
        value: 'mm'
    }, {
        label: "Hours",
        value: 'hh'
    }];


    $scope.inactivity_settings = {
        status: false,
        inactive_time: 60 * 5 * 3, // 15 min (default value), that is, 900 seconds
        //time_format: 'ss', // Second (default value)
        time_format: $scope.timeFormatTemplates[0], // Default seconds object
    };

    $scope.activity_settings = {
        status: false,
        active_time: 60 * 5 * 3, // 15 min (default value), that is,  900 seconds
        //time_format: 'ss', // Second (default value)
        time_format: $scope.timeFormatTemplates[0], // Default seconds object
    };

    $scope.changedTimeFormat = function (time_format) {
        'use strict';

        console.log('time changed');
        console.log(time_format);
        var newValue = time_format.value;

        // do your update settings stuffs
    }
});

As you can see in the fiddle output, whatever you choose for select box options, it is your custom value, or the 0, 1, 2 auto generated value by AngularJS, it does not matter in your output unless you are using jQuery or any other library to access the value of that select combo box options and manipulate it accordingly.

private void button26_Click(object sender, EventArgs e)
{
    System.Diagnostics.ProcessStartInfo proc = new System.Diagnostics.ProcessStartInfo();
    proc.FileName = @"C:\windows\system32\cmd.exe";
    proc.Arguments = "/c ping -t " + tx1.Text + " ";
    System.Diagnostics.Process.Start(proc);
    tx1.Focus();
}

private void button27_Click(object sender, EventArgs e)
{
    System.Diagnostics.ProcessStartInfo proc = new System.Diagnostics.ProcessStartInfo();
    proc.FileName = @"C:\windows\system32\cmd.exe";
    proc.Arguments = "/c ping  " + tx2.Text + " ";
    System.Diagnostics.Process.Start(proc);
    tx2.Focus();

I know its long after this question was asked and answered - and I am sure that the accepted solution is right, but the purist in me would rather not add an extra element to the SVG when I can achieve the same or similar with straight CSS.

Whilst it is true that you cannot style the g container element in most ways - you can definitely add an outline to it and style that - even changing it on hover of the g - as shown in the snippet.

It not as good in one regard as the other way - you can put the outline box around the grouped elements - but not a background behind it. Sot its not perfect and won't solve the issue for everyone - but I would rather have the outline done with css than have to add extra elements to the code just to provide styling hooks.

And this method definitely allows you to show grouping of related objects in your SVG's.

Just a thought.

g {_x000D_
    outline: solid 3px blue;_x000D_
    outline-offset: 5px;_x000D_
  }_x000D_
_x000D_
g:hover {_x000D_
 outline-color: red_x000D_
}

<svg width="640" height="480" xmlns="http://www.w3.org/2000/svg">_x000D_
  <g>_x000D_
    <rect fill="blue" stroke-width="2" height="112" width="84" y="55" x="55" stroke-linecap="null" stroke-linejoin="null" stroke-dasharray="null" stroke="#000000"/>_x000D_

I faced the same issues. To solve this, I used export PYTHONPATH="$PWD". However, in this case, you will need to modify imports in your Scripts dir depending on the below:

Case 1: If you are in the user_management dir, your scripts should use this style from Modules import LDAPManager to import module.

Case 2: If you are out of the user_management 1 level like main, your scripts should use this style from user_management.Modules import LDAPManager to import modules.

Use a ScheduledExecutorService:

 private final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);
 scheduler.scheduleAtFixedRate(yourRunnable, 8, 8, TimeUnit.HOURS);

In my case the error was some old username and password was stored in cache.

So I removed it by going to sourceTree and delete the existing account.

Now for the new clone then it will ask you for the password for the repo.

The problem is the name saved in the table migrations inside database, because in my database exists 2017_10_18_200000_name and in files 2016_10_18_200000_name, after change the name of file that work.

So please don't change your file's name for migrations files because the name must be the same according to the last migration.

Solution by recursion

function count(arr, value) {
   if (arr.length === 1)    {
      return arr[0] === value ? 1 : 0;
   } else {
      return (arr.shift() === value ? 1 : 0) + count(arr, value);
   }
}

count([1,2,2,3,4,5,2], 2); // 3

You could launch a coroutine, delay it and then call the function:

 /*GlobalScope.*/launch {
   delay(1000)
   yourFn()
 }

If you are outside of a class or object prepend GlobalScope to let the coroutine run there, otherwise it is recommended to implement the CoroutineScope in the surrounding class, which allows to cancel all coroutines associated to that scope if necessary.

Spaces are simply replaced by "%20" like :

http://www.example.com/my%20beautiful%20page

When you write

df['Date'] = pd.to_datetime(df['Date'], errors='coerce')
df['Date'] = df['Date'].dt.strftime('%m/%d')

It can fixed

Change detection

Only @Component can be a node in the change detection tree. This means that you cannot set ChangeDetectionStrategy.OnPush in a @Directive. Despite this fact, a Directive can have @Input and @Output properties and you can inject and manipulate host component's ChangeDetectorRef from it. So use Components when you need a granular control over your change detection tree.

The question is bigger than just using wither static_cast or C style casting because there are different things that happen when using C style casts. The C++ casting operators are intended to make these operations more explicit.

On the surface static_cast and C style casts appear to the same thing, for example when casting one value to another:

int i;
double d = (double)i;                  //C-style cast
double d2 = static_cast<double>( i );  //C++ cast

Both of these cast the integer value to a double. However when working with pointers things get more complicated. some examples:

class A {};
class B : public A {};

A* a = new B;
B* b = (B*)a;                                  //(1) what is this supposed to do?

char* c = (char*)new int( 5 );                 //(2) that weird?
char* c1 = static_cast<char*>( new int( 5 ) ); //(3) compile time error

In this example (1) maybe OK because the object pointed to by A is really an instance of B. But what if you don't know at that point in code what a actually points to? (2) maybe perfectly legal(you only want to look at one byte of the integer), but it could also be a mistake in which case an error would be nice, like (3). The C++ casting operators are intended to expose these issues in the code by providing compile-time or run-time errors when possible.

So, for strict "value casting" you can use static_cast. If you want run-time polymorphic casting of pointers use dynamic_cast. If you really want to forget about types, you can use reintrepret_cast. And to just throw const out the window there is const_cast.

They just make the code more explicit so that it looks like you know what you were doing.

If you have a std::wstring object, you can call c_str() on it to get a wchar_t*:

std::wstring name( L"Steve Nash" );
const wchar_t* szName = name.c_str();

Since you are operating on a narrow string, however, you would first need to widen it. There are various options here; one is to use Windows' built-in MultiByteToWideChar routine. That will give you an LPWSTR, which is equivalent to wchar_t*.

The href is probably generated in a javascript function. For example with jQuery:

$(function() {
    $('a.view').attr('href', 'http://www.google.com');
});

First of all, a spinner does not support item click events. Calling this method will raise an exception.

You can use setOnItemSelectedListener:

Spinner s1;
s1 = (Spinner)findViewById(R.id.s1);
int selectionCurrent = s1.getSelectedItemPosition();

spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> parentView, View selectedItemView, int position, long id) {
            if (selectionCurrent != position){
                // Your code here
            }
            selectionCurrent= position;
        }
    }

    @Override
    public void onNothingSelected(AdapterView<?> parentView) {
        // Your code here
    }
});

You have to implement KeyListener,take a look here: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyListener.html

More details on how to use it: http://docs.oracle.com/javase/tutorial/uiswing/events/keylistener.html

Java docs clearly stated that:

The prohibition against using null as a switch label prevents one from writing code that can never be executed. If the switch expression is of a reference type, such as a boxed primitive type or an enum, a run-time error will occur if the expression evaluates to null at run-time.

You must have to verify for null before Swithch statement execution.

if (i == null)

See The Switch Statement

case null: // will never be executed, therefore disallowed.

Best solution for expand/collapse view's:

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        View view = buttonView.getId() == R.id.tb_search ? fSearch : layoutSettings;
        transform(view, 200, isChecked
            ? ViewGroup.LayoutParams.WRAP_CONTENT
            : 0);
    }

    public static void transform(final View v, int duration, int targetHeight) {
        int prevHeight  = v.getHeight();
        v.setVisibility(View.VISIBLE);
        ValueAnimator animator;
        if (targetHeight == ViewGroup.LayoutParams.WRAP_CONTENT) {
            v.measure(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            animator = ValueAnimator.ofInt(prevHeight, v.getMeasuredHeight());
        } else {
            animator = ValueAnimator.ofInt(prevHeight, targetHeight);
        }
        animator.addUpdateListener(animation -> {
            v.getLayoutParams().height = (animation.getAnimatedFraction() == 1.0f)
                    ? targetHeight
                    : (int) animation.getAnimatedValue();
            v.requestLayout();
        });
        animator.setInterpolator(new LinearInterpolator());
        animator.setDuration(duration);
        animator.start();
    }

I got this, the only way I found to fix this was to update all of mingw-64 (I did this using pacman on msys2 for your information).

You can set the style attribute of any element... the trick is that in IE you have to do it differently. (bug 245)

//Standards base browsers
elem.setAttribute('style', styleString);

//Non Standards based IE browser
elem.style.setAttribute('cssText', styleString);

Note that in IE8, in Standards Mode, the first way does work.

Have you tried to delete and re install the device in your Apple Developer portal? If yes, try to upgrade your xcode to 4.3.2, I remember that I needed to update to xCode 4.3.2 after updating my iPhone to iOS 5.1

In addition to the already posted answer, I thought I should share a handy trick I use to load all the DLL functions into the program through function pointers, without writing a separate GetProcAddress call for each and every function. I also like to call the functions directly as attempted in the OP.

Start by defining a generic function pointer type:

typedef int (__stdcall* func_ptr_t)();

What types that are used aren't really important. Now create an array of that type, which corresponds to the amount of functions you have in the DLL:

func_ptr_t func_ptr [DLL_FUNCTIONS_N];

In this array we can store the actual function pointers that point into the DLL memory space.

Next problem is that GetProcAddress expects the function names as strings. So create a similar array consisting of the function names in the DLL:

const char* DLL_FUNCTION_NAMES [DLL_FUNCTIONS_N] = 
{
  "dll_add",
  "dll_subtract",
  "dll_do_stuff",
  ...
};

Now we can easily call GetProcAddress() in a loop and store each function inside that array:

for(int i=0; i<DLL_FUNCTIONS_N; i++)
{
  func_ptr[i] = GetProcAddress(hinst_mydll, DLL_FUNCTION_NAMES[i]);

  if(func_ptr[i] == NULL)
  {
    // error handling, most likely you have to terminate the program here
  }
}

If the loop was successful, the only problem we have now is calling the functions. The function pointer typedef from earlier isn't helpful, because each function will have its own signature. This can be solved by creating a struct with all the function types:

typedef struct
{
  int  (__stdcall* dll_add_ptr)(int, int);
  int  (__stdcall* dll_subtract_ptr)(int, int);
  void (__stdcall* dll_do_stuff_ptr)(something);
  ...
} functions_struct;

And finally, to connect these to the array from before, create a union:

typedef union
{
  functions_struct  by_type;
  func_ptr_t        func_ptr [DLL_FUNCTIONS_N];
} functions_union;

Now you can load all the functions from the DLL with the convenient loop, but call them through the by_type union member.

But of course, it is a bit burdensome to type out something like

functions.by_type.dll_add_ptr(1, 1); whenever you want to call a function.

As it turns out, this is the reason why I added the "ptr" postfix to the names: I wanted to keep them different from the actual function names. We can now smooth out the icky struct syntax and get the desired names, by using some macros:

#define dll_add (functions.by_type.dll_add_ptr)
#define dll_subtract (functions.by_type.dll_subtract_ptr)
#define dll_do_stuff (functions.by_type.dll_do_stuff_ptr)

And voilà, you can now use the function names, with the correct type and parameters, as if they were statically linked to your project:

int result = dll_add(1, 1);

Disclaimer: Strictly speaking, conversions between different function pointers are not defined by the C standard and not safe. So formally, what I'm doing here is undefined behavior. However, in the Windows world, function pointers are always of the same size no matter their type and the conversions between them are predictable on any version of Windows I've used.

Also, there might in theory be padding inserted in the union/struct, which would cause everything to fail. However, pointers happen to be of the same size as the alignment requirement in Windows. A static_assert to ensure that the struct/union has no padding might be in order still.

The urls are different.

• http://localhost/AccountSvc/DataInquiry.asmx

vs.

• /acctinqsvc/portfolioinquiry.asmx

Resolve this issue first, as if the web server cannot resolve the URL you are attempting to POST to, you won't even begin to process the actions described by your request.

You should only need to create the WebRequest to the ASMX root URL, ie: http://localhost/AccountSvc/DataInquiry.asmx, and specify the desired method/operation in the SOAPAction header.

The SOAPAction header values are different.

• http://localhost/AccountSvc/DataInquiry.asmx/ + methodName

vs.

• http://tempuri.org/GetMyName

You should be able to determine the correct SOAPAction by going to the correct ASMX URL and appending ?wsdl

There should be a <soap:operation> tag underneath the <wsdl:operation> tag that matches the operation you are attempting to execute, which appears to be GetMyName.

There is no XML declaration in the request body that includes your SOAP XML.

You specify text/xml in the ContentType of your HttpRequest and no charset. Perhaps these default to us-ascii, but there's no telling if you aren't specifying them!

The SoapUI created XML includes an XML declaration that specifies an encoding of utf-8, which also matches the Content-Type provided to the HTTP request which is: text/xml; charset=utf-8

Hope that helps!

I've been using this function for a while. it returns a boolean value.

// Validates email address of course.
function validEmail(e) {
    var filter = /^\s*[\w\-\+_]+(\.[\w\-\+_]+)*\@[\w\-\+_]+\.[\w\-\+_]+(\.[\w\-\+_]+)*\s*$/;
    return String(e).search (filter) != -1;
}

Uhm, what's wrong with this:

#include <iostream>

using namespace std;

int main(int, char **)
{
    char c = 'A';

    int x = c; // Look ma! No cast!

    cout << "The character '" << c << "' has an ASCII code of " << x << endl;

    return 0;
}

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);

The definitive answer to this is from Facebook themselves. In post today at https://developers.facebook.com/bugs/335452696581712 a Facebook dev says

The ability to pass in an e-mail address into the "user" search type was
removed on July 10, 2013. This search type only returns results that match
a user's name (including alternate name).

So, alas, the simple answer is you can no longer search for users by their email address. This sucks, but that's Facebook's new rules.

there should has a concurrent implemention of List interface supporting such operation.

This below code just show the very basic use of delegate concept .. you name the variable and class as per your requirement.

First you need to declare a protocol:

Let's call it MyFirstControllerDelegate.h

@protocol MyFirstControllerDelegate
- (void) FunctionOne: (MyDataOne*) dataOne;
- (void) FunctionTwo: (MyDatatwo*) dataTwo;
@end

Import MyFirstControllerDelegate.h file and confirm your FirstController with protocol MyFirstControllerDelegate

#import "MyFirstControllerDelegate.h"

@interface FirstController : UIViewController<MyFirstControllerDelegate>
{

}

@end

In the implementation file, you need to implement both functions of protocol:

@implementation FirstController 


    - (void) FunctionOne: (MyDataOne*) dataOne
      {
          //Put your finction code here
      }
    - (void) FunctionTwo: (MyDatatwo*) dataTwo
      {
          //Put your finction code here
      }

     //Call below function from your code
    -(void) CreateSecondController
     {
             SecondController *mySecondController = [SecondController alloc] initWithSomeData:.];
           //..... push second controller into navigation stack 
            mySecondController.delegate = self ;
            [mySecondController release];
     }

@end

in your SecondController:

@interface SecondController:<UIViewController>
{
   id <MyFirstControllerDelegate> delegate;
}

@property (nonatomic,assign)  id <MyFirstControllerDelegate> delegate;

@end

In the implementation file of SecondController.

@implementation SecondController

@synthesize delegate;
//Call below two function on self.
-(void) SendOneDataToFirstController
{
   [delegate FunctionOne:myDataOne];
}
-(void) SendSecondDataToFirstController
{
   [delegate FunctionTwo:myDataSecond];
}

@end

Here is the wiki article on delegate.

Swift 3/4/5 Solution

Select Row

let indexPath = IndexPath(row: 0, section: 0)
tblView.selectRow(at: indexPath, animated: true, scrollPosition: .bottom)
myTableView.delegate?.tableView!(myTableView, didSelectRowAt: indexPath)

DeSelect Row

let deselectIndexPath = IndexPath(row: 7, section: 0)
tblView.deselectRow(at: deselectIndexPath, animated: true)
tblView.delegate?.tableView!(tblView, didDeselectRowAt: indexPath)

You can do:

ssh user@host 'bash -s' < /path/script.sh

You can use basic css to achieve smooth scroll

html {
  scroll-behavior: smooth;
}

You can set a control variable in vars files located in group_vars/ or directly in hosts file like this:

[vagrant:vars]
test_var=true

[location-1]
192.168.33.10 hostname=apollo

[location-2]
192.168.33.20 hostname=zeus

[vagrant:children]
location-1
location-2

And run tasks like this:

- name: "test"
  command: "echo {{test_var}}"
  when: test_var is defined and test_var

Unfortunately, it seems that Git has no such command built in. But you can easily add it yourself with Git aliases and some shell magic.

As pointed out by this answer, you can use git rev-parse --show-toplevel to show the root of your current Git folder.

If you want to use this regularly, it's probably more convenient to define it as an alias. For this, used git config alias.root '!echo "$(git rev-parse --show-toplevel)"'. After this, you can use git root to see the root folder of the repository you're currently in.

If you want to use another subcommand name than root, simply replace the second part of alias.root in the above command with whatever you want.

For details on aliases in Git, see also the git config man page.

char means exactly one character. You can't assign zero characters to this type.

That means that there is no char value for which String.replace(char, char) would return a string with a diffrent length.

Along with the above answers, do also consider this site; https://google-webfonts-helper.herokuapp.com/fonts

Advantage:

• allows you to self-host those google fonts for better response times

• choose your font(s)

• choose your character set
• choose your font styles/weight
• choose your target browser
• and u get the CSS snippets ( add to your css stylesheet ) plus a zip of the font files to include in your project

E.g your_theme.css

@font-face { 
    font-family: 'Open Sans'; 
    font-style: normal;  
    font-weight: 400;
    src: local('Open Sans Regular'), local('OpenSans-Regular'),
             url('css_fonts/open-sans-v15-latin-regular.woff2') format('woff2'), 
             url('css_fonts/open-sans-v15-latin-regular.woff') format('woff'); 
}

You need to intent your current context to another activity first with startActivity. After that you can finish your current activity from where you redirect.

 Intent intent = new Intent(this, FirstActivity.class);// New activity
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 finish(); // Call once you redirect to another activity

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) - Clears the activity stack. If you don't want to clear the activity stack. PLease don't use that flag then.

It's included in Jasny's fork of bootstrap.

A simple upload button can be created using

<span class="btn btn-file">Upload<input type="file" /></span>

With the fileupload plugin you can create more advanced widgets. Have a look at http://jasny.github.io/bootstrap/javascript/#fileinput

function get_mime($file) {
  if (function_exists("finfo_file")) {
    $finfo = finfo_open(FILEINFO_MIME_TYPE); // return mime type ala mimetype extension
    $mime = finfo_file($finfo, $file);
    finfo_close($finfo);
    return $mime;
  } else if (function_exists("mime_content_type")) {
    return mime_content_type($file);
  } else if (!stristr(ini_get("disable_functions"), "shell_exec")) {
    // http://stackoverflow.com/a/134930/1593459
    $file = escapeshellarg($file);
    $mime = shell_exec("file -bi " . $file);
    return $mime;
  } else {
    return false;
  }
}

For me, nothing of this does work - mime_content_type is deprecated, finfo is not installed, and shell_exec is not allowed.

from collections import OrderedDict
OrderedDict((word, True) for word in words)

contains

OrderedDict([('He', True), ('will', True), ('be', True), ('the', True), ('winner', True)])

If the values are True (or any other immutable object), you can also use:

OrderedDict.fromkeys(words, True)
