There is an odd case I got in VS2017, about the space between ‘Any’ and 'CPU'. this is not about using command prompt.

If you have a build project file, which could call other solution files. You can try to add the space between Any and CPU, like this (the Platform property value):

<MSBuild Projects="@(SolutionToBuild2)" Properties ="Configuration=$(ProjectConfiguration);Platform=Any CPU;Rerun=$(MsBuildReRun);" />

Before I fix this build issue, it is like this (ProjectPlatform is a global variable, was set to 'AnyCPU'):

<MSBuild Projects="@(SolutionToBuild1)" Properties ="Configuration=$(ProjectConfiguration);Platform=$(ProjectPlatform);Rerun=$(MsBuildReRun);" />

Also, we have a lot projects being called using $ (ProjectPlatform), which is 'AnyCPU' and work fine. If we open proj file, we can see lines liket this and it make sense.

<PropertyGroup Condition="'$(Configuration)|$(Platform)' == 'Release|AnyCPU'">

So my conclusion is, 'AnyCPU' works for calling project files, but not for calling solution files, for calling solution files, using 'Any CPU' (add the space.)

For now, I am not sure if it is a bug of VS project file or MSBuild. I am using VS2017 with VS2017 build tools installed.

This might help:

1) "Build" menu -> "Rebuild Project". Sometimes Intellij doesn't rewrite the classes because they already exist, this way you ask Intellij to rewrite everything.

2) "Run" menu -> "Edit configuration" -> delete the profile -> add back the profile ("Application" if it's a Java application), choose your main class from the "Main Class" dropdown menu.

3)"Build" menu -> "Rebuild Project".

Here is a detailed explanation about what Gradle is and how to use it in Android Studio.

Exploring the Gradle Files

1. Whenever you create a project in Android Studio, the build system automatically generates all the necessary Gradle build files.

Gradle Build Files

2. Gradle build files use a Domain Specific Language or DSL to define custom build logic and to interact with the Android-specific elements of the Android plugin for Gradle.

3. Android Studio projects consists of 1 or more modules, which are components that you can build, test, and debug independently. Each module has its own build file, so every Android Studio project contains 2 kinds of Gradle build files.

4. Top-Level Build File: This is where you'll find the configuration options that are common to all the modules that make up your project.

5. Module-Level Build File: Each module has its own Gradle build file that contains module-specific build settings. You'll spend most of your time editing module-level build file(s) rather than your project's top-level build file.

To take a look at these build.gradle files, open Android Studio's Project panel (by selecting the Project tab) and expand the Gradle Scripts folder. The first two items in the Gradle Scripts folder are the project-level and module-level Gradle build files

Top-Level Gradle Build File

Every Android Studio project contains a single, top-level Gradle build file. This build.gradle file is the first item that appears in the Gradle Scripts folder and is clearly marked Project.

Most of the time, you won't need to make any changes to this file, but it's still useful to understand its contents and the role it plays within your project.

Module-Level Gradle Build Files

In addition to the project-level Gradle build file, each module has a Gradle build file of its own. Below is an annotated version of a basic, module-level Gradle build file.

Other Gradle Files

In addition to the build.gradle files, your Gradle Scripts folder contains some other Gradle files. Most of the time you won't have to manually edit these files as they'll update automatically when you make any relevant changes to your project. However, it's a good idea to understand the role these files play within your project.

gradle-wrapper.properties (Gradle Version)

This file allows other people to build your code, even if they don't have Gradle installed on their machine. This file checks whether the correct version of Gradle is installed and downloads the necessary version if necessary.

settings.gradle

This file references all the modules that make up your project.

gradle.properties (Project Properties)

This file contains configuration information for your entire project. It's empty by default, but you can apply a wide range of properties to your project by adding them to this file.

local.properties (SDK Location)

This file tells the Android Gradle plugin where it can find your Android SDK installation.

Note: local.properties contains information that's specific to the local installation of the Android SDK. This means that you shouldn't keep this file under source control.

I got clear understanding of gradle from this.

So I got things working (based on @user1671599 answer) and wanted to share it with you guys.

(I hope I'm doing it right since it's my first app in Python)

I did this -

Project structure:

server.py:

from server.AppStarter import AppStarter
import os

static_folder_root = os.path.join(os.path.dirname(os.path.abspath(__file__)), "client")

app = AppStarter()
app.register_routes_to_resources(static_folder_root)
app.run(__name__)

AppStarter.py:

from flask import Flask, send_from_directory
from flask_restful import Api, Resource
from server.ApiResources.TodoList import TodoList
from server.ApiResources.Todo import Todo


class AppStarter(Resource):
    def __init__(self):
        self._static_files_root_folder_path = ''  # Default is current folder
        self._app = Flask(__name__)  # , static_folder='client', static_url_path='')
        self._api = Api(self._app)

    def _register_static_server(self, static_files_root_folder_path):
        self._static_files_root_folder_path = static_files_root_folder_path
        self._app.add_url_rule('/<path:file_relative_path_to_root>', 'serve_page', self._serve_page, methods=['GET'])
        self._app.add_url_rule('/', 'index', self._goto_index, methods=['GET'])

    def register_routes_to_resources(self, static_files_root_folder_path):

        self._register_static_server(static_files_root_folder_path)
        self._api.add_resource(TodoList, '/todos')
        self._api.add_resource(Todo, '/todos/<todo_id>')

    def _goto_index(self):
        return self._serve_page("index.html")

    def _serve_page(self, file_relative_path_to_root):
        return send_from_directory(self._static_files_root_folder_path, file_relative_path_to_root)

    def run(self, module_name):
        if module_name == '__main__':
            self._app.run(debug=True)

Hibernate has to put the disclaimer about not using auto updates in prod to cover themselves when people who don't know what they are doing use it in situations where it should not be used.

Granted the situations where it should not be used greatly outnumber the ones where it's OK.

I have used it for years on lots of different projects and have never had a single issue. That's not a lame answer, and it's not cowboy coding. It's a historic fact.

A person who says "never do it in production" is thinking of a specific set of production deployments, namely the ones he is familiar with (his company, his industry, etc).

The universe of "production deployments" is vast and varied.

An experienced Hibernate developer knows exactly what DDL is going to result from a given mapping configuration. As long as you test and validate that what you expect ends up in the DDL (in dev, qa, staging, etc), you are fine.

When you are adding lots of features, auto schema updates can be a real time saver.

The list of stuff auto updates won't handle is endless, but some examples are data migration, adding non-nullable columns, column name changes, etc, etc.

Also you need to take care in clustered environments.

But then again, if you knew all this stuff, you wouldn't be asking this question. Hmm . . . OK, if you are asking this question, you should wait until you have lots of experience with Hibernate and auto schema updates before you think about using it in prod.

I had similar error: "Expecting value: line 1 column 1 (char 0)"

It helped for me to add "myfile.seek(0)", move the pointer to the 0 character

with open(storage_path, 'r') as myfile:
if len(myfile.readlines()) != 0:
    myfile.seek(0)
    Bank_0 = json.load(myfile)

Imports System.Net
Imports System.Net.Sockets
Function LocalIP()
    Dim strHostName = Dns.GetHostName
    Dim Host = Dns.GetHostEntry(strHostName)
    For Each ip In Host.AddressList
        If ip.AddressFamily = AddressFamily.InterNetwork Then
            txtIP.Text = ip.ToString
        End If
    Next

    Return True
End Function

Below same action

Function LocalIP()

   Dim Host As String =Dns.GetHostEntry(Dns.GetHostName).AddressList(1).MapToIPv4.ToString

   txtIP.Text = Host

   Return True

End Function

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

You need to turn it on its head in terms of the way you're thinking about it. Instead of doing "in" to find the current item's user rights in a predefined set of applicable user rights, you're asking a predefined set of user rights if it contains the current item's applicable value. This is exactly the same way you would find an item in a regular list in .NET.

There are two ways of doing this using LINQ, one uses query syntax and the other uses method syntax. Essentially, they are the same and could be used interchangeably depending on your preference:

Query Syntax:

var selected = from u in users
               where new[] { "Admin", "User", "Limited" }.Contains(u.User_Rights)
               select u

foreach(user u in selected)
{
    //Do your stuff on each selected user;
}

Method Syntax:

var selected = users.Where(u => new[] { "Admin", "User", "Limited" }.Contains(u.User_Rights));

foreach(user u in selected)
{
    //Do stuff on each selected user;
}

My personal preference in this instance might be method syntax because instead of assigning the variable, I could do the foreach over an anonymous call like this:

foreach(User u in users.Where(u => new [] { "Admin", "User", "Limited" }.Contains(u.User_Rights)))
{
    //Do stuff on each selected user;
}

Syntactically this looks more complex, and you have to understand the concept of lambda expressions or delegates to really figure out what's going on, but as you can see, this condenses the code a fair amount.

It all comes down to your coding style and preference - all three of my examples do the same thing slightly differently.

An alternative way doesn't even use LINQ, you can use the same method syntax replacing "where" with "FindAll" and get the same result, which will also work in .NET 2.0:

foreach(User u in users.FindAll(u => new [] { "Admin", "User", "Limited" }.Contains(u.User_Rights)))
{
    //Do stuff on each selected user;
}

exec

executes a command and never returns. It's like a return statement in a function.

If the command is not found exec returns false. It never returns true, because if the command is found it never returns at all. There is also no point in returning STDOUT, STDERR or exit status of the command. You can find documentation about it in perlfunc, because it is a function.

system

executes a command and your Perl script is continued after the command has finished.

The return value is the exit status of the command. You can find documentation about it in perlfunc.

backticks

like system executes a command and your perl script is continued after the command has finished.

In contrary to system the return value is STDOUT of the command. qx// is equivalent to backticks. You can find documentation about it in perlop, because unlike system and execit is an operator.

Other ways

What is missing from the above is a way to execute a command asynchronously. That means your perl script and your command run simultaneously. This can be accomplished with open. It allows you to read STDOUT/STDERR and write to STDIN of your command. It is platform dependent though.

There are also several modules which can ease this tasks. There is IPC::Open2 and IPC::Open3 and IPC::Run, as well as Win32::Process::Create if you are on windows.

Try this (using "Results to text"):

SELECT
ISNULL(smsp.definition, ssmsp.definition) AS [Definition]
FROM
sys.all_objects AS sp
LEFT OUTER JOIN sys.sql_modules AS smsp ON smsp.object_id = sp.object_id
LEFT OUTER JOIN sys.system_sql_modules AS ssmsp ON ssmsp.object_id = sp.object_id
WHERE
(sp.type = N'V' OR sp.type = N'P' OR sp.type = N'RF' OR sp.type=N'PC')and(sp.name=N'YourObjectName' and SCHEMA_NAME(sp.schema_id)=N'dbo')

• C: Check constraint
• D: Default constraint
• F: Foreign Key constraint
• L: Log
• P: Stored procedure
• PK: Primary Key constraint
• RF: Replication Filter stored procedure
• S: System table

I don't have reputation to comment yet, but I want to add to alko answer for further reference.

From the docs:

skiprows: A collection of numbers for rows in the file to skip. Can also be an integer to skip the first n rows

We're trying this on a short list that does not do any view recycling. So far so good.

XML:

<RitalinLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
  <ListView
      android:id="@+id/cart_list"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:scrollbarStyle="outsideOverlay"
      />
</RitalinLayout>

Java:

/**
 * It helps you keep focused.
 *
 * For use as a parent of {@link android.widget.ListView}s that need to use EditText
 * children for inline editing.
 */
public class RitalinLayout extends FrameLayout {
  View sticky;

  public RitalinLayout(Context context, AttributeSet attrs) {
    super(context, attrs);

    ViewTreeObserver vto = getViewTreeObserver();

    vto.addOnGlobalFocusChangeListener(new ViewTreeObserver.OnGlobalFocusChangeListener() {
      @Override public void onGlobalFocusChanged(View oldFocus, View newFocus) {
        if (newFocus == null) return;

        View baby = getChildAt(0);

        if (newFocus != baby) {
          ViewParent parent = newFocus.getParent();
          while (parent != null && parent != parent.getParent()) {
            if (parent == baby) {
              sticky = newFocus;
              break;
            }
            parent = parent.getParent();
          }
        }
      }
    });

    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
      @Override public void onGlobalLayout() {
        if (sticky != null) {
          sticky.requestFocus();
        }
      }
    });
  }
}

I used this import:

import java.util.Date;

And declared my variable like this:

Date studentEnrollementDate;

An alternative is to look for a unix shell which does give you logical operators and a whole lot more. You can get a native win32 implementation of a Bourne shell here if you don't want to go the cygwin route. A native bash can be found here. I'm quite certain you could easily google other good alternatives such as zsh or tcsh.

K

If you use instanceof, making your equals implementation final will preserve the symmetry contract of the method: x.equals(y) == y.equals(x). If final seems restrictive, carefully examine your notion of object equivalence to make sure that your overriding implementations fully maintain the contract established by the Object class.

I hope this one might help you.

let data = [];
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };

let tempData = [];

tempData= data.filter((item)=>item.Status!='Invalid')

console.log(tempData)

You can not use DATEDIFF but you can use this (if columns are not date type):

SELECT 
to_date('2008-08-05','YYYY-MM-DD')-to_date('2008-06-05','YYYY-MM-DD') 
AS DiffDate from dual

you can see the sample

You should look at the documentation for the Action method; it's explained well. For your case, this should work:

@Html.Action("GetOptions", new { pk="00", rk="00" });

The controllerName parameter will default to the controller from which Html.Action is being invoked. So if you're trying to invoke an action from another controller, you'll have to specify the controller name like so:

@Html.Action("GetOptions", "ControllerName", new { pk="00", rk="00" });

var dt = new Date()  //current date of week
var currentWeekDay = dt.getDay();
var lessDays = currentWeekDay == 0 ? 6 : currentWeekDay-1
var wkStart = new Date(new Date(dt).setDate(dt.getDate()- lessDays));
var wkEnd = new Date(new Date(wkStart).setDate(wkStart.getDate()+6));

This will be useful for any date scenario.

For my situation, I switched the value of "fork" to false, such as <fork>false</fork>. I do not understand why, hope someone could explain to me. Thanks in advance.

Emacs is a wonderful text editor. It has huge power once you become a power user. You can access a shell, have as many files open as you want in as many sub-windows and an extremely powerful scripting support that lets you add all kinds of neat features.

I have been using a ruby-mode which adds syntax highlighting and whatnot to ruby, and the same exists for every major language.

If you keep at it, you can use exclusively the keyboard and never touch the mouse, which increases your editing speed by a significant margin.

If you want to start with something a lot more basic though, gedit is nice... it has built in syntax highlighting as well for most languages based on the filename extension. It comes with the OS as well (though emacs you can easily install with apt-get or some similar package finder utility).

UPDATE: I think gedit is exclusively GUI based though, so it would be useful to learn emacs in case you are stuck with just a shell (it is fully featured in both shell and graphical mode).

FURTHER UPDATE: Just FYI, I am not trying to push Emacs over Vim, it's just what I use, and it's a great editor (as I'm sure Vim is too). It is daunting at first (as I'm sure Vim is too), but the question was about text editors on Linux besides vi... Emacs seems the logical choice to me, but gedit is a great simple text editor with some nice features if that's all you are looking for.

If you propagate the exception by declaring the throws directive in the signature of the current method, then somewhere up the line or call stack a try/catch construct must be used to handle the exception.

The answers above are good, but insufficient if you have more than 1 project (.csproj) in the same folder.

First, you easily add the "PackageReference" tag to the .csproj file (either manually, by using the nuget package manager or by using the dotnet add package command).

But then, you need to run the "restore" command manually so you can tell it which project you are trying to restore (if I just clicked the restore button that popped up, nothing happened). You can do that by running:

dotnet restore Project-File-Name.csproj

And that installs the package

My solution looks much like Tims but also works in case of non-worksheet sheets - charts

Public Function SheetExists(strSheetName As String, Optional wbWorkbook As Workbook) As Boolean
    If wbWorkbook Is Nothing Then Set wbWorkbook = ActiveWorkbook 'or ThisWorkbook - whichever appropriate
    Dim obj As Object
    On Error GoTo HandleError
    Set obj = wbWorkbook.Sheets(strSheetName)
    SheetExists = True
    Exit Function
HandleError:
    SheetExists = False
End Function

.

Open the Run Configuration for your application (Run/Run Configurations..., then look for the applications entry in 'Java application').

The arguments tab has a text box Vm arguments, enter -Xss1m (or a bigger parameter for the maximum stack size). The default value is 512 kByte (SUN JDK 1.5 - don't know if it varies between vendors and versions).

It's totally feasible now. Google now allow you to transfer Android apps between accounts. Please take a look at this link: https://support.google.com/googleplay/android-developer/checklist/3294213?hl=en

why not simply eg

var newList = list1.Union(list2)/*.Distinct()*//*.ToList()*/;

oh ... according to the documentation you can leave out the .Distinct()

This method excludes duplicates from the return set

You could use d3py a python module that generate xml pages embedding d3.js script. For example :

import d3py
import networkx as nx

import logging
logging.basicConfig(level=logging.DEBUG)

G = nx.Graph()
G.add_edge(1,2)
G.add_edge(1,3)
G.add_edge(3,2)
G.add_edge(3,4)
G.add_edge(4,2)

# use 'with' if you are writing a script and want to serve this up forever
with d3py.NetworkXFigure(G, width=500, height=500) as p:
    p += d3py.ForceLayout()
    p.show()

The caller and the callee need to use the same convention at the point of invokation - that's the only way it could reliably work. Both the caller and the callee follow a predefined protocol - for example, who needs to clean up the stack. If conventions mismatch your program runs into undefined behavior - likely just crashes spectacularly.

This is only required per invokation site - the calling code itself can be a function with any calling convention.

You shouldn't notice any real difference in performance between those conventions. If that becomes a problem you usually need to make less calls - for example, change the algorithm.

There is a single quote in $submitsubject or $submit_message

Why is this a problem?

The single quote char terminates the string in MySQL and everything past that is treated as a sql command. You REALLY don't want to write your sql like that. At best, your application will break intermittently (as you're observing) and at worst, you have just introduced a huge security vulnerability.

Imagine if someone submitted '); DROP TABLE private_messages; in submit message.

Your SQL Command would be:

INSERT INTO private_messages (to_id, from_id, time_sent, subject, message) 
        VALUES('sender_id', 'id', now(),'subjet','');

DROP TABLE private_messages;

Instead you need to properly sanitize your values.

AT A MINIMUM you must run each value through mysql_real_escape_string() but you should really be using prepared statements.

If you were using mysql_real_escape_string() your code would look like this:

if($_POST['submit_message']){

if($_POST['form_subject']==""){
    $submit_subject="(no subject)";
}else{
    $submit_subject=mysql_real_escape_string($_POST['form_subject']); 
}
$submit_message=mysql_real_escape_string($_POST['form_message']);
$sender_id = mysql_real_escape_string($_POST['sender_id']);

Here is a great article on prepared statements and PDO.

If you want to set typeface to all the TextViews in the entire Activity you can use something like this:

public static void setTypefaceToAll(Activity activity)
{
    View view = activity.findViewById(android.R.id.content).getRootView();
    setTypefaceToAll(view);
}

public static void setTypefaceToAll(View view)
{
    if (view instanceof ViewGroup)
    {
        ViewGroup g = (ViewGroup) view;
        int count = g.getChildCount();
        for (int i = 0; i < count; i++)
            setTypefaceToAll(g.getChildAt(i));
    }
    else if (view instanceof TextView)
    {
        TextView tv = (TextView) view;
        setTypeface(tv);
    }
}

public static void setTypeface(TextView tv)
{
    TypefaceCache.setFont(tv, TypefaceCache.FONT_KOODAK);
}

And the TypefaceCache:

import java.util.TreeMap;

import android.graphics.Typeface;
import android.widget.TextView;

public class TypefaceCache {

    //Font names from asset:
    public static final String FONT_ROBOTO_REGULAR = "fonts/Roboto-Regular.ttf";
    public static final String FONT_KOODAK = "fonts/Koodak.ttf";

    private static TreeMap<String, Typeface> fontCache = new TreeMap<String, Typeface>();

    public static Typeface getFont(String fontName) {
        Typeface tf = fontCache.get(fontName);
        if(tf == null) {
            try {
                tf = Typeface.createFromAsset(MyApplication.getAppContext().getAssets(), fontName);
            }
            catch (Exception e) {
                return null;
            }
            fontCache.put(fontName, tf);
        }
        return tf;
    }

    public static void setFont(TextView tv, String fontName)
    {
        tv.setTypeface(getFont(fontName));
    }
}

If this is regarding a class you created, be sure that the class is not nested.

F.e

A.swift

class A {

   class ARelated {

   }
}

calling var b = ARelated() will give 'Use of unresolved identifier: ARelated'.

You can either:

1) separate the classes if wanted on the same file:

A.swift

class A {

}

class ARelated {

}

2) Maintain your same structure and use the enclosing class to get to the subclass:

var b = A.ARelated

$result = array();
foreach ($array as $key => $value){
  if(!in_array($value, $result))
    $result[$key]=$value;
}

More things can be done with keyboard module. You can install this module using pip install keyboard Here are some of the methods:

Method #1:

Using the function read_key():

import keyboard

while True:
    if keyboard.read_key() == "p":
        print("You pressed p")
        break

This is gonna break the loop as the key p is pressed.

Method #2:

Using function wait:

import keyboard

keyboard.wait("p")
print("You pressed p")

It will wait for you to press p and continue the code as it is pressed.

Method #3:

Using the function on_press_key:

import keyboard

keyboard.on_press_key("p", lambda _:print("You pressed p"))

It needs a callback function. I used _ because the keyboard function returns the keyboard event to that function.

Once executed, it will run the function when the key is pressed. You can stop all hooks by running this line:

keyboard.unhook_all()

Method #4:

This method is sort of already answered by user8167727 but I disagree with the code they made. It will be using the function is_pressed but in an other way:

import keyboard

while True:
    if keyboard.is_pressed("p"):
        print("You pressed p")
        break

It will break the loop as p is pressed.

Notes:

• keyboard will read keypresses from the whole OS.
• keyboard requires root on linux

For Oracle, I highly recommend the free Oracle SQL Developer

http://www.oracle.com/technology/products/database/sql_developer/index.html

The doucmentation states it also works with non-oracle databases - i've never tried that feature myself, but I do know that it works really well with Oracle

It's worth to mention that using concerns is considered bad idea by many.

1. like this guy
2. and this one

Some reasons:

1. There is some dark magic happening behind the scenes - Concern is patching include method, there is a whole dependency handling system - way too much complexity for something that's trivial good old Ruby mixin pattern.
2. Your classes are no less dry. If you stuff 50 public methods in various modules and include them, your class still has 50 public methods, it's just that you hide that code smell, sort of put your garbage in the drawers.
3. Codebase is actually harder to navigate with all those concerns around.
4. Are you sure all members of your team have same understanding what should really substitute concern?

Concerns are easy way to shoot yourself in the leg, be careful with them.

If you don't wanted to use PIP install atall, then you could do the following:

1) Download the package 2) Use 7 zip for unzipping tar files. ( Use 7 zip again until you see a folder by the name of the package you are looking for. Ex: wordcloud)

3) Locate Python library folder where python is installed and paste the 'WordCloud' folder itself there

4) Success !! Now you can import the library and start using the package.

There are a number of "is methods" on strings. islower() and isupper() should meet your needs:

>>> 'hello'.islower()
True

>>> [m for m in dir(str) if m.startswith('is')]
['isalnum', 'isalpha', 'isdigit', 'islower', 'isspace', 'istitle', 'isupper']

Here's an example of how to use those methods to classify a list of strings:

>>> words = ['The', 'quick', 'BROWN', 'Fox', 'jumped', 'OVER', 'the', 'Lazy', 'DOG']
>>> [word for word in words if word.islower()]
['quick', 'jumped', 'the']
>>> [word for word in words if word.isupper()]
['BROWN', 'OVER', 'DOG']
>>> [word for word in words if not word.islower() and not word.isupper()]
['The', 'Fox', 'Lazy']

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus "collision"). Finding a collision using a birthday attack takes O(2^(n/2)) time, where n is the output length of the hash function in bits.

SHA-2 has an output size of 512 bits, so finding a collision would take O(2^256) time. Given there are no clever attacks on the algorithm itself (currently none are known for the SHA-2 hash family) this is what it takes to break the algorithm.

To get a feeling for what 2^256 actually means: currently it is believed that the number of atoms in the (entire!!!) universe is roughly 10^80 which is roughly 2^266. Assuming 32 byte input (which is reasonable for your case - 20 bytes salt + 12 bytes password) my machine takes ~0,22s (~2^-2s) for 65536 (=2^16) computations. So 2^256 computations would be done in 2^240 * 2^16 computations which would take

2^240 * 2^-2 = 2^238 ~ 10^72s ~ 3,17 * 10^64 years

Even calling this millions of years is ridiculous. And it doesn't get much better with the fastest hardware on the planet computing thousands of hashes in parallel. No human technology will be able to crunch this number into something acceptable.

So forget brute-forcing SHA-256 here. Your next question was about dictionary words. To retrieve such weak passwords rainbow tables were used traditionally. A rainbow table is generally just a table of precomputed hash values, the idea is if you were able to precompute and store every possible hash along with its input, then it would take you O(1) to look up a given hash and retrieve a valid preimage for it. Of course this is not possible in practice since there's no storage device that could store such enormous amounts of data. This dilemma is known as memory-time tradeoff. As you are only able to store so many values typical rainbow tables include some form of hash chaining with intermediary reduction functions (this is explained in detail in the Wikipedia article) to save on space by giving up a bit of savings in time.

Salts were a countermeasure to make such rainbow tables infeasible. To discourage attackers from precomputing a table for a specific salt it is recommended to apply per-user salt values. However, since users do not use secure, completely random passwords, it is still surprising how successful you can get if the salt is known and you just iterate over a large dictionary of common passwords in a simple trial and error scheme. The relationship between natural language and randomness is expressed as entropy. Typical password choices are generally of low entropy, whereas completely random values would contain a maximum of entropy.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords. If you google for them, you will end up finding torrent links for such password databases, often in the gigabyte size category. Being successful with such a tool is usually in the range of minutes to days if the attacker is not restricted in any way.

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5 and you should enforce a waiting period for a given user before they may retry entering their password. A good scheme is to start with 0.5s and then doubling that time for each failed attempt. In most cases users don't notice this and don't fail much more often than three times on average. But it will significantly slow down any malicious outsider trying to attack your application.

Why is the WebSockets protocol better?

I don't think we can compare them side by side like who is better. That won't be a fair comparison simply because they are solving two different problems. Their requirements are different. It will be like comparing apples to oranges. They are different.

HTTP is a request-response protocol. The client (browser) wants something, the server gives it. That is. If the data client wants is big, the server might send streaming data to void unwanted buffer problems. Here the main requirement or problem is how to make the request from clients and how to response the resources(hypertext) they request. That is where HTTP shine.

In HTTP, only client requests. The server only responds.

WebSocket is not a request-response protocol where only the client can request. It is a socket(very similar to TCP socket). Mean once the connection is open, either side can send data until the underlining TCP connection is closed. It is just like a normal socket. The only difference with TCP socket is WebSocket can be used on the web. On the web, we have many restrictions on a normal socket. Most firewalls will block other ports than 80 and 433 that HTTP used. Proxies and intermediaries will be problematic as well. So to make the protocol easier to deploy to existing infrastructures WebSocket use HTTP handshake to upgrade. That means when the first time connection is going to open, the client sent an HTTP request to tell the server saying "That is not HTTP request, please upgrade to WebSocket protocol".

Upgrade: websocket
Connection: Upgrade
Sec-WebSocket-Key: x3JJHMbDL1EzLkh9GBhXDw==
Sec-WebSocket-Protocol: chat, superchat
Sec-WebSocket-Version: 13

Once the server understands the request and upgraded to WebSocket protocol, none of the HTTP protocols applied anymore.

So my answer is Neither one is better than each other. They are completely different.

Why was it implemented instead of updating the HTTP protocol?

Well, we can make everything under the name called HTTP as well. But shall we? If they are two different things, I will prefer two different names. So do Hickson and Michael Carter .

For returning multiple column indices, I recommend using the pandas.Index method get_indexer, if you have unique labels:

df = pd.DataFrame({"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]})
df.columns.get_indexer(['pear', 'apple'])
# Out: array([0, 1], dtype=int64)

If you have non-unique labels in the index (columns only support unique labels) get_indexer_for. It takes the same args as get_indeder:

df = pd.DataFrame(
    {"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]}, 
    index=[0, 1, 1])
df.index.get_indexer_for([0, 1])
# Out: array([0, 1, 2], dtype=int64)

Both methods also support non-exact indexing with, f.i. for float values taking the nearest value with a tolerance. If two indices have the same distance to the specified label or are duplicates, the index with the larger index value is selected:

df = pd.DataFrame(
    {"pear": [1, 2, 3], "apple": [2, 3, 4], "orange": [3, 4, 5]},
    index=[0, .9, 1.1])
df.index.get_indexer([0, 1])
# array([ 0, -1], dtype=int64)

Working with a dictionary ->level2 above comes from a dictionary in my case (just in case anybody will find it useful) Trying the first example I stumbled over this error: "This document already has a 'DocumentElement' node." I was inspired by the answer here

and edited my code: (xmlDoc.DocumentElement.AppendChild(body))

//a dictionary:
Dictionary<string, string> Level2Data 
{
    {"level2", "text"},
    {"level2", "other text"},
    {"same_level2", "more text"}
}
//xml Decalration:
XmlDocument xmlDoc = new XmlDocument();
XmlDeclaration xmlDeclaration = xmlDoc.CreateXmlDeclaration("1.0", "UTF-8", null);
XmlElement root = xmlDoc.DocumentElement;
xmlDoc.InsertBefore(xmlDeclaration, root);
// add body
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.AppendChild(body);
XmlElement body = xmlDoc.CreateElement(string.Empty, "body", string.Empty);
xmlDoc.DocumentElement.AppendChild(body); //without DocumentElement ->ERR



foreach (KeyValuePair<string, string> entry in Level2Data)
{
    //write to xml: - it works version 1.
    XmlNode keyNode = xmlDoc.CreateElement(entry.Key); //open TAB
    keyNode.InnerText = entry.Value;
    body.AppendChild(keyNode); //close TAB

    //Write to xmml verdion 2: (uncomment the next 4 lines and comment the above 3 - version 1
    //XmlElement key = xmlDoc.CreateElement(string.Empty, entry.Key, string.Empty);
    //XmlText value = xmlDoc.CreateTextNode(entry.Value);
    //key.AppendChild(value);
    //body.AppendChild(key);
}

Both versions (1 and 2 inside foreach loop) give the output:

<?xml version="1.0" encoding="UTF-8"?>
<body>
    <level1>
        <level2>text</level2>
        <level2>ther text</level2>
         <same_level2>more text</same_level2>
    </level1>
</body>

(Note: third line "same level2" in dictionary can be also level2 as the others but I wanted to ilustrate the advantage of the dictionary - in my case I needed level2 with different names.

First way is

function function1()
{
  var variable1=12;
  function2(variable1);
}

function function2(val)
{
  var variableOfFunction1 = val;

// Then you will have to use this function for the variable1 so it doesn't really help much unless that's what you want to do. }

Second way is

var globalVariable;
function function1()
{
  globalVariable=12;
  function2();
}

function function2()
{
  var local = globalVariable;
}

To compare entire revisions, it's simply:

svn diff -r 8979:11390

If you want to compare the last committed state against your currently saved working files, you can use convenience keywords:

svn diff -r PREV:HEAD

(Note, without anything specified afterwards, all files in the specified revisions are compared.)

You can compare a specific file if you add the file path afterwards:

svn diff -r 8979:HEAD /path/to/my/file.php

1. you can create your own new network like --net="anyname"
2. this is done to isolate the services from different container.
3. suppose the same service are running in different containers, but the port mapping remains same, the first container starts well , but the same service from second container will fail. so to avoid this, either change the port mappings or create a network.

You can set the color on the entire app navigation's bar using the method

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:
(NSDictionary *)launchOptions{
    [[UINavigationBar appearance] setTintColor:[UIColor whiteColor]];
}

Although there is no publicly exposed method, a method does exist in the internal class System.Data.ProviderBase.FieldNameLookup which SqlDataReader relies on.

In order to access it and get native performance, you must use the ILGenerator to create a method at runtime. The following code will give you direct access to int IndexOf(string fieldName) in the System.Data.ProviderBase.FieldNameLookup class as well as perform the book keeping that SqlDataReader.GetOrdinal()does so that there is no side effect. The generated code mirrors the existing SqlDataReader.GetOrdinal() except that it calls FieldNameLookup.IndexOf() instead of FieldNameLookup.GetOrdinal(). The GetOrdinal() method calls to the IndexOf() function and throws an exception if -1 is returned, so we bypass that behavior.

You could have Flash call the function when it's done. I'm not sure what you mean by web services. I assume you have JavaScript code calling web services via Ajax, in which case you would know when they terminate. In the worst case, you could do a looping setTimeout that would check every 100 ms or so.

And the check for whether or not a variable is defined can be just if (myVariable) or safer: if(typeof myVariable == "undefined")

I hit this error calling:

I fixed this with:

If the machine you are on is part of the AD domain, it should have its name servers set to the AD name servers (or hopefully use a DNS server path that will eventually resolve your AD domains). Using your example of dc=domain,dc=com, if you look up domain.com in the AD name servers it will return a list of the IPs of each AD Controller. Example from my company (w/ the domain name changed, but otherwise it's a real example):

    mokey 0 /home/jj33 > nslookup example.ad
    Server:         172.16.2.10
    Address:        172.16.2.10#53

    Non-authoritative answer:
    Name:   example.ad
    Address: 172.16.6.2
    Name:   example.ad
    Address: 172.16.141.160
    Name:   example.ad
    Address: 172.16.7.9
    Name:   example.ad
    Address: 172.19.1.14
    Name:   example.ad
    Address: 172.19.1.3
    Name:   example.ad
    Address: 172.19.1.11
    Name:   example.ad
    Address: 172.16.3.2

Note I'm actually making the query from a non-AD machine, but our unix name servers know to send queries for our AD domain (example.ad) over to the AD DNS servers.

I'm sure there's a super-slick windowsy way to do this, but I like using the DNS method when I need to find the LDAP servers from a non-windows server.

Since you are still getting duplicate using only UNION I would check that:

• That they are exact duplicates. I mean, if you make a

  SELECT DISTINCT * FROM (<your query>) AS subquery

  you do get fewer files?

• That you don't have already the duplicates in the first part of the query (maybe generated by the left join). As I understand it UNION it will not add to the result set rows that are already on it, but it won't remove duplicates already present in the first data set.

You could try

NumberUtils.isParsable(yourInput)

It is part of org/apache/commons/lang3/math/NumberUtils and it checks whether the string can be parsed by Integer.parseInt(String), Long.parseLong(String), Float.parseFloat(String) or Double.parseDouble(String).

See below:

https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/math/NumberUtils.html#isParsable-java.lang.String-

This is a hacky method, but i tried it twice with different numbers and it seems to be consistent.

What you can do is to try and allocate a huge number of objects, like one or two million objects of the kind you want. Put the objects in an array to prevent the garbage collector from releasing them (note that this will add a slight memory overhead because of the array, but i hope this shouldn't matter and besides if you are going to worry about objects being in memory, you store them somewhere). Add an alert before and after the allocation and in each alert check how much memory the Firefox process is taking. Before you open the page with the test, make sure you have a fresh Firefox instance. Open the page, note the memory usage after the "before" alert is shown. Close the alert, wait for the memory to be allocated. Subtract the new memory from the older and divide it by the amount of allocations. Example:

function Marks()
{
  this.maxMarks = 100;
}

function Student()
{
  this.firstName = "firstName";
  this.lastName = "lastName";
  this.marks = new Marks();
}

var manyObjects = new Array();
alert('before');
for (var i=0; i<2000000; i++)
    manyObjects[i] = new Student();
alert('after');

I tried this in my computer and the process had 48352K of memory when the "before" alert was shown. After the allocation, Firefox had 440236K of memory. For 2million allocations, this is about 200 bytes for each object.

I tried it again with 1million allocations and the result was similar: 196 bytes per object (i suppose the extra data in 2mill was used for Array).

So, here is a hacky method that might help you. JavaScript doesn't provide a "sizeof" method for a reason: each JavaScript implementaion is different. In Google Chrome for example the same page uses about 66 bytes for each object (judging from the task manager at least).

 git reset HEAD@{4}

4 is changes before 4 steps ago. if you select a correct step, it should show the list of files that you removed from hard. then do:

$ git reflog show

it's going to show you local commit history we've already created. now do:

$ git reset --hard 8c4d112

8c4d112 is a code you want to reset your hard there. let's look at https://www.theserverside.com/video/How-to-use-the-git-reset-hard-command-to-change-a-commit-history to get more information.

The command you're looking for is rem, short for "remark".

There is also a shorthand version :: that some people use, and this sort of looks like # if you squint a bit and look at it sideways. I originally preferred that variant since I'm a bash-aholic and I'm still trying to forget the painful days of BASIC :-)

Unfortunately, there are situations where :: stuffs up the command line processor (such as within complex if or for statements) so I generally use rem nowadays. In any case, it's a hack, suborning the label infrastructure to make it look like a comment when it really isn't. For example, try replacing rem with :: in the following example and see how it works out:

if 1==1 (
    rem comment line 1
    echo 1 equals 1
    rem comment line 2
)

You should also keep in mind that rem is a command, so you can't just bang it at the end of a line like the # in bash. It has to go where a command would go. For example, only the second of these two will echo the single word hello:

echo hello rem a comment.
echo hello & rem a comment.

Using unzip

unzip -c whatever.war META-INF/MANIFEST.MF  

It will print the output in terminal.

And for extracting all the files,

 unzip whatever.war

Using jar

jar xvf test.war

Note! The jar command will extract war contents to current directory. Not to a subdirectory (like Tomcat does).

Here you can simply use:

SendKeys "{ENTER}" at the end of code linked to the Username field.

And so you can skip pressing ENTER Key once (one time).
And as a result, the next button ("Log In" button here) will be activated. And when you press ENTER once (your desired outcome), It will run code which is linked with "Log In" button.

The present solution produces the same flow as your OP. It does not use Labels, but this was not a requirement of the OP. You only asked for "a simple conditional loop that will go to the next iteration if a condition is true", and since this is cleaner to read, it is likely a better option than that using a Label.

What you want inside your for loop follows the pattern

If (your condition) Then
    'Do something
End If

In this case, your condition is Not(Return = 0 And Level = 0), so you would use

For i = 2 To 24
    Level = Cells(i, 4)
    Return = Cells(i, 5)

    If (Not(Return = 0 And Level = 0)) Then
        'Do something
    End If
Next i

PS: the condition is equivalent to (Return <> 0 Or Level <> 0)

WITH    q AS 
        (
        SELECT  *
        FROM    mytable
        WHERE   ParentID IS NULL -- this condition defines the ultimate ancestors in your chain, change it as appropriate
        UNION ALL
        SELECT  m.*
        FROM    mytable m
        JOIN    q
        ON      m.parentID = q.PersonID
        )
SELECT  *
FROM    q

By adding the ordering condition, you can preserve the tree order:

WITH    q AS 
        (
        SELECT  m.*, CAST(ROW_NUMBER() OVER (ORDER BY m.PersonId) AS VARCHAR(MAX)) COLLATE Latin1_General_BIN AS bc
        FROM    mytable m
        WHERE   ParentID IS NULL
        UNION ALL
        SELECT  m.*,  q.bc + '.' + CAST(ROW_NUMBER() OVER (PARTITION BY m.ParentID ORDER BY m.PersonID) AS VARCHAR(MAX)) COLLATE Latin1_General_BIN
        FROM    mytable m
        JOIN    q
        ON      m.parentID = q.PersonID
        )
SELECT  *
FROM    q
ORDER BY
        bc

By changing the ORDER BY condition you can change the ordering of the siblings.

I ran across the same issue this morning. It turned out to be a simple issue. I had a query window open that was set to the single user database in the object explorer. The sp_who2 stored procedure did not show then connection. Once I closed it, I was able to set it to

Using regedit, remove the entries corresponding to java 7. It will work.

A .crt stores the certificate.. in pem format. So a .pem, while it can also have other things like a csr (Certificate signing request), a private key, a public key, or other certs, when it is storing just a cert, is the same thing as a .crt.

A pem is a base 64 encoded file with a header and a footer between each section.

To extract a particular section, a perl script such as the following is totally valid, but feel free to use some of the openssl commands.

 perl -ne "\$n++ if /BEGIN/; print if \$n == 1 && /BEGIN/.../END/;" mydomain.pem

where ==1 can be changed to which ever section you need. Obviously if you know exactly the header and footer you require and there is only one of those in the file (usually the case if you keep just the cert and the key in there), you can simplify it:

Just to chime in, Emanuel had the answer that I (and probably many others) are looking for. If you have 3d scattered data in 3 separate arrays, pandas is an incredible help and works much better than the other options. To elaborate, suppose your x,y,z are some arbitrary variables. In my case these were c,gamma, and errors because I was testing a support vector machine. There are many potential choices to plot the data:

• scatter3D(cParams, gammas, avg_errors_array) - this works but is overly simplistic
• plot_wireframe(cParams, gammas, avg_errors_array) - this works, but will look ugly if your data isn't sorted nicely, as is potentially the case with massive chunks of real scientific data
• ax.plot3D(cParams, gammas, avg_errors_array) - similar to wireframe

Wireframe plot of the data

3d scatter of the data

The code looks like this:

    fig = plt.figure()
    ax = fig.gca(projection='3d')
    ax.set_xlabel('c parameter')
    ax.set_ylabel('gamma parameter')
    ax.set_zlabel('Error rate')
    #ax.plot_wireframe(cParams, gammas, avg_errors_array)
    #ax.plot3D(cParams, gammas, avg_errors_array)
    #ax.scatter3D(cParams, gammas, avg_errors_array, zdir='z',cmap='viridis')

    df = pd.DataFrame({'x': cParams, 'y': gammas, 'z': avg_errors_array})
    surf = ax.plot_trisurf(df.x, df.y, df.z, cmap=cm.jet, linewidth=0.1)
    fig.colorbar(surf, shrink=0.5, aspect=5)    
    plt.savefig('./plots/avgErrs_vs_C_andgamma_type_%s.png'%(k))
    plt.show()

Here is the final output:

$(function(){

    $('#check').click(function(){
        if( $('#myButton').prop('disabled') ) { 
            alert('disabled'); 
            $('#myButton').prop('disabled',false);
        } 
        else {
            alert('enabled');
            $('#myButton').prop('disabled',true);
        }
    });
});

The only difference between the two elements is semantics. Both elements, by default, have the CSS rule display: block (hence block-level) applied to them; nothing more (except somewhat extra margin in some instances). However, as aforementioned, they both different greatly in terms of semantics.

The <p> element, as its name somewhat implies, is for paragraphs. Thus, <p> should be used when you want to create blocks of paragraph text.

The <div> element, however, has little to no meaning semantically and therefore can be used as a generic block-level element — most commonly, people use it within layouts because it is meaningless semantically and can be used for generally anything you might require a block-level element for.

Unfortunately, C++ does not allow you to directly get a callable object referring to an object and one of its member functions. &Foo::doSomething gives you a "pointer to member function" which refers to the member function but not the associated object.

There are two ways around this, one is to use std::bind to bind the "pointer to member function" to the this pointer. The other is to use a lambda that captures the this pointer and calls the member function.

std::function<void(void)> f = std::bind(&Foo::doSomething, this);
std::function<void(void)> g = [this](){doSomething();};

I would prefer the latter.

With g++ at least binding a member function to this will result in an object three-pointers in size, assigning this to an std::function will result in dynamic memory allocation.

On the other hand, a lambda that captures this is only one pointer in size, assigning it to an std::function will not result in dynamic memory allocation with g++.

While I have not verified this with other compilers, I suspect similar results will be found there.

What did you put exactly in lib, jre/lib or jre/lib/ext? Was it the jar mysql-connector-java-5.1.5-bin.jar or something else (like a directory)?

By the way, I wouldn't put it in lib, jre/lib or jre/lib/ext, there are other ways to add a jar to the classpath. You can do that by adding it explicitly the CLASSPATH environment variable. Or you can use the -cp option of java. But this is another story.

In the specific case of a Rails action (as opposed to the general case of getting the current method name) you can use params[:action]

Alternatively you might want to look into customising the Rails log format so that the action/method name is included by the format rather than it being in your log message.

I've implemented a library with a category on UIViewController that simplifies this operation. Basically, you set the parameters you want to pass over in a NSDictionary associated to the UI item that is performing the segue. It works with manual segues too.

For example, you can do

[self performSegueWithIdentifier:@"yourIdentifier" parameters:@{@"customParam1":customValue1, @"customValue2":customValue2}];

for a manual segue or create a button with a segue and use

[button setSegueParameters:@{@"customParam1":customValue1, @"customValue2":customValue2}];

If destination view controller is not key-value coding compliant for a key, nothing happens. It works with key-values too (useful for unwind segues). Check it out here https://github.com/stefanomondino/SMQuickSegue

A fixed point number has a specific number of bits (or digits) reserved for the integer part (the part to the left of the decimal point) and a specific number of bits reserved for the fractional part (the part to the right of the decimal point). No matter how large or small your number is, it will always use the same number of bits for each portion. For example, if your fixed point format was in decimal IIIII.FFFFF then the largest number you could represent would be 99999.99999 and the smallest non-zero number would be 00000.00001. Every bit of code that processes such numbers has to have built-in knowledge of where the decimal point is.

A floating point number does not reserve a specific number of bits for the integer part or the fractional part. Instead it reserves a certain number of bits for the number (called the mantissa or significand) and a certain number of bits to say where within that number the decimal place sits (called the exponent). So a floating point number that took up 10 digits with 2 digits reserved for the exponent might represent a largest value of 9.9999999e+50 and a smallest non-zero value of 0.0000001e-49.

Just in case, any one still lingering around this question. Because, i see one or two new users again asking the same question and everyone telling then , No you can't do that, Dear Prudence, Apart from all the answers given here, I would like to provide additional Information - Yes you can actually do, List list = new List(); But at the cost of writing implementations of all the methods of Interfaces. The notion is not simply List list = new List(); but

List<Integer> list = new List<Integer>(){

        @Override
        public int size() {
            // TODO Auto-generated method stub
            return 0;
        }

        @Override
        public boolean isEmpty() {
            // TODO Auto-generated method stub
            return false;
        }

        @Override
        public boolean contains(Object o) {
            // TODO Auto-generated method stub
            return false;
        }

..... and So on (Cant write all methods.)

This is an example of Anonymous class. Its correct when someone states , No you cant instantiate an interface, and that's right. But you can never say , You CANT write List list = new List(); but, evidently you can do that and that's a hard statement to make that You can't do.

Is there a js listener for when a user scrolls in a certain textbox that can be used?

DOM L3 UI Events spec gave the initial definition but is considered obsolete.

To add a single handler you can do:

  let isTicking;
  const debounce = (callback, evt) => {
    if (isTicking) return;
    requestAnimationFrame(() => {
      callback(evt);
      isTicking = false;
    });
    isTicking = true;
  };
  const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
  document.defaultView.onscroll = evt => debounce(handleScroll, evt);

For multiple handlers or, if preferable for style reasons, you may use addEventListener as opposed to assigning your handler to onscroll as shown above.

If using something like _.debounce from lodash you could probably get away with:

const handleScroll = evt => console.log(evt, window.scrollX, window.scrollY);
document.defaultView.onscroll = evt => _.debounce(() => handleScroll(evt));

Review browser compatibility and be sure to test on some actual devices before calling it done.

You can use date:'yyyy-MM-dd' pipe

curDate=new Date();

<p>{{curDate | date:'yyyy-MM-dd'}}</p>

To see a list of HTTP request headers, you can use :

console.log(JSON.stringify(req.headers));

to return a list in JSON format.

{
"host":"localhost:8081",
"connection":"keep-alive",
"cache-control":"max-age=0",
"accept":"text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8",
"upgrade-insecure-requests":"1",
"user-agent":"Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.107 Safari/537.36",
"accept-encoding":"gzip, deflate, sdch",
"accept-language":"en-US,en;q=0.8,et;q=0.6"
}

On SmtpClient there is an EnableSsl property that you would set.

i.e.

SmtpClient client = new SmtpClient(exchangeServer);
client.EnableSsl = true;
client.Send(msg);

user.no_of_logins += 1
session.commit()

Another option is to use mouse, right click on "x reference". Context menu "CodeLens Options" will appear, saving all the navigation headache.

You had two problems:

1) The order in which you included the HTML. Try changing the dropdown from "onLoad" to "no wrap - head" in the JavaScript settings of your fiddle.

2) Your function prints the values. What you're actually after is the text

x.options[i].text; instead of x.options[i].value;

I tend to use yield-return when I calculate the next item in the list (or even the next group of items).

Using your Version 2, you must have the complete list before returning. By using yield-return, you really only need to have the next item before returning.

Among other things, this helps spread the computational cost of complex calculations over a larger time-frame. For example, if the list is hooked up to a GUI and the user never goes to the last page, you never calculate the final items in the list.

Another case where yield-return is preferable is if the IEnumerable represents an infinite set. Consider the list of Prime Numbers, or an infinite list of random numbers. You can never return the full IEnumerable at once, so you use yield-return to return the list incrementally.

In your particular example, you have the full list of products, so I'd use Version 2.

Something that worked for me was to override the finishUpdate method, which is called at the end of a transition and do the notifyDataSetChanged() there:

public class MyPagerAdapter extends FragmentPagerAdapter {
    ...
    @Override
    public void finishUpdate(ViewGroup container) {
        super.finishUpdate(container);
        this.notifyDataSetChanged();
    }
    ...
}

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

Check the version of the excel, if you are using older version then Value2 is not available for you and thus it is showing an error, while it will work with 2007+ version. Or the other way, the object is not getting created and thus the Value2 property is not available for the object.

Use a regex literal with the g modifier, and escape the forward slash with a backslash so it doesn't clash with the delimiters.

var str = 'some // slashes', replacement = '';
var replaced = str.replace(/\//g, replacement);

I solved changing

readable_json['firstName']

by

readable_json[0]['firstName']

The animate(..) function' signature is:

.animate( properties, options );

And it says the following about the parameter properties:

properties A map of CSS properties that the animation will move toward.

text is not a CSS property, this is why the function isn't working as you expected.

Do you want to fade the text out? Do you want to move it? I might be able to provide an alternative.

Have a look at the following fiddle.

request.getSession() is just a convenience method. It does exactly the same as request.getSession(true).

You can do

JLabel l = new JLabel("<html><p>Hello World! blah blah blah</p></html>", SwingConstants.CENTER);

and it will automatically wrap it where appropriate.

The list of valid characters is in the XML specification:

Char       ::=      #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]  /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */

When using an EF model, I have a connection string in each project that consumes the EF model. For example, I have an EF EDMX model in a separate class library. I have one connection string in my web (mvc) project so that it can access the EF db.

I also have another unit test project for testing the repositories. In order for the repositories to access the EF db, the test project's app.config file has the same connection string.

DB connections should be configured, not coded, IMO.

I find this at google: https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

It mentiones that we need to

1. Update Gradle version to gradle-4.1-all ( changegradle-wrapper.properties by distributionUrl=\https\://services.gradle.org/distributions/gradle-4.1-all.zip
2. Add google() to repositories repositories { google() } and dependencies { classpath 'com.android.tools.build:gradle:3.0.0-beta7' }

You may require to have Android Studio 3

Install a stable version instead of the latest one, I have downgrade my version to node-v0.10.29-x86.msi from 'node-v0.10.33-x86.msi' and it is working well for me!

http://blog.nodejs.org/2014/06/16/node-v0-10-29-stable/

using JQuery:

myelement=$("#myelement")
[myelement.offset().left, myelement.offset().top,  myelement.width(), myelement.height()]

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

I did it with jQuery:

page.execute_script %Q{ $('#some_id').prop('checked', true) }

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

I am not quite sure what you need, but I would use something like this:

#!/usr/bin/env ruby

until ARGV.empty? do
  puts "From arguments: #{ARGV.shift}"
end

while a = gets
  puts "From stdin: #{a}"
end

Note that because ARGV array is empty before first gets, Ruby won't try to interpret argument as text file from which to read (behaviour inherited from Perl).

If stdin is empty or there is no arguments, nothing is printed.

Few test cases:

$ cat input.txt | ./myprog.rb
From stdin: line 1
From stdin: line 2

$ ./myprog.rb arg1 arg2 arg3
From arguments: arg1
From arguments: arg2
From arguments: arg3
hi!
From stdin: hi!

for speed you can do this

WHERE date(created_at) ='2019-10-21'

In my opinion the bare minimum implementation has two requirements. A state that keeps track of whether the modal is open or not, and a portal to render the modal outside of the standard react tree.

The ModalContainer component below implements those requirements along with corresponding render functions for the modal and the trigger, which is responsible for executing the callback to open the modal.

import React from 'react';
import PropTypes from 'prop-types';
import Portal from 'react-portal';

class ModalContainer extends React.Component {
  state = {
    isOpen: false,
  };

  openModal = () => {
    this.setState(() => ({ isOpen: true }));
  }

  closeModal = () => {
    this.setState(() => ({ isOpen: false }));
  }

  renderModal() {
    return (
      this.props.renderModal({
        isOpen: this.state.isOpen,
        closeModal: this.closeModal,
      })
    );
  }

  renderTrigger() {
     return (
       this.props.renderTrigger({
         openModal: this.openModal
       })
     )
  }

  render() {
    return (
      <React.Fragment>
        <Portal>
          {this.renderModal()}
        </Portal>
        {this.renderTrigger()}
      </React.Fragment>
    );
  }
}

ModalContainer.propTypes = {
  renderModal: PropTypes.func.isRequired,
  renderTrigger: PropTypes.func.isRequired,
};

export default ModalContainer;

And here's a simple use case...

import React from 'react';
import Modal from 'react-modal';
import Fade from 'components/Animations/Fade';
import ModalContainer from 'components/ModalContainer';

const SimpleModal = ({ isOpen, closeModal }) => (
  <Fade visible={isOpen}> // example use case with animation components
    <Modal>
      <Button onClick={closeModal}>
        close modal
      </Button>
    </Modal>
  </Fade>
);

const SimpleModalButton = ({ openModal }) => (
  <button onClick={openModal}>
    open modal
  </button>
);

const SimpleButtonWithModal = () => (
   <ModalContainer
     renderModal={props => <SimpleModal {...props} />}
     renderTrigger={props => <SimpleModalButton {...props} />}
   />
);

export default SimpleButtonWithModal;

I use render functions, because I want to isolate state management and boilerplate logic from the implementation of the rendered modal and trigger component. This allows the rendered components to be whatever you want them to be. In your case, I suppose the modal component could be a connected component that receives a callback function that dispatches an asynchronous action.

If you need to send dynamic props to the modal component from the trigger component, which hopefully doesn't happen too often, I recommend wrapping the ModalContainer with a container component that manages the dynamic props in its own state and enhance the original render methods like so.

import React from 'react'
import partialRight from 'lodash/partialRight';
import ModalContainer from 'components/ModalContainer';

class ErrorModalContainer extends React.Component {
  state = { message: '' }

  onError = (message, callback) => {
    this.setState(
      () => ({ message }),
      () => callback && callback()
    );
  }

  renderModal = (props) => (
    this.props.renderModal({
       ...props,
       message: this.state.message,
    })
  )

  renderTrigger = (props) => (
    this.props.renderTrigger({
      openModal: partialRight(this.onError, props.openModal)
    })
  )

  render() {
    return (
      <ModalContainer
        renderModal={this.renderModal}
        renderTrigger={this.renderTrigger}
      />
    )
  }
}

ErrorModalContainer.propTypes = (
  ModalContainer.propTypes
);

export default ErrorModalContainer;

Tells the iterator that it's reached the end.

As an example:

public interface INode
{
    IEnumerable<Node> GetChildren();
}

public class NodeWithTenChildren : INode
{
    private Node[] m_children = new Node[10];

    public IEnumerable<Node> GetChildren()
    {
        for( int n = 0; n < 10; ++n )
        {
            yield return m_children[ n ];
        }
    }
}

public class NodeWithNoChildren : INode
{
    public IEnumerable<Node> GetChildren()
    {
        yield break;
    }
}

You can use setTimeout to do this

function myFunction() {
    // your code to run after the timeout
}

// stop for sometime if needed
setTimeout(myFunction, 5000);

Facebook uses Bit.ly's services to shorten links from their site. While pages that have a username turns into "fb.me/<username>", other links associated with Facebook turns into "on.fb.me/*****". To you use the on.fb.me service, just use your Bit.ly account. Note that if you change the default link shortener on your Bit.ly account to j.mp from bit.ly this service won't work.

Date.now() returns a unix timestamp in milliseconds.

const now = Date.now(); // Unix timestamp in milliseconds_x000D_
console.log( now );

Prior to ECMAScript5 (I.E. Internet Explorer 8 and older) you needed to construct a Date object, from which there are several ways to get a unix timestamp in milliseconds:

console.log( +new Date );_x000D_
console.log( (new Date).getTime() );_x000D_
console.log( (new Date).valueOf() );

Use inputstream once don't use it multiple times and Do inputstream.close()

In Python 3.x, 5 / 2 will return 2.5 and 5 // 2 will return 2. The former is floating point division, and the latter is floor division, sometimes also called integer division.

In Python 2.2 or later in the 2.x line, there is no difference for integers unless you perform a from __future__ import division, which causes Python 2.x to adopt the 3.x behavior.

Regardless of the future import, 5.0 // 2 will return 2.0 since that's the floor division result of the operation.

You can find a detailed description at https://docs.python.org/whatsnew/2.2.html#pep-238-changing-the-division-operator

If you have latest compiler, you can change the following in your build settings:

 C++ Language Dialect    C++14[-std=c++14]

This works for me.

The above answers are pretty good. My only complaint is that you can't clear the value once it's been set. Also I prefer the extend-jquery-like-a-plugin approach.

This works perfect for me:

$.fn.monthYearPicker = function(options) {
    options = $.extend({
        dateFormat: "MM yy",
        changeMonth: true,
        changeYear: true,
        showButtonPanel: true,
        showAnim: ""
    }, options);
    function hideDaysFromCalendar() {
        var thisCalendar = $(this);
        $('.ui-datepicker-calendar').detach();
        // Also fix the click event on the Done button.
        $('.ui-datepicker-close').unbind("click").click(function() {
            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
            thisCalendar.datepicker('setDate', new Date(year, month, 1));
        });
    }
    $(this).datepicker(options).focus(hideDaysFromCalendar);
}

Then invoke like so:

$('input.monthYearPicker').monthYearPicker();

For anyone else who did all the advice but the problem still persists.

Check for stored procedure and view DEFINERS. Those definers may no longer exists.

My problem showed up when we changed the wildcard host (%) to IP specific, making the database more secure. Unfortunately there are some views that are still using 'user'@'%' even though 'user'@'172....' is technically correct.

Actually, using the converter like that breaks two-way binding, plus as I said above, you can't use that with enumerations either. The better way to do this is with a simple style against a ListBox, like this:

Note: Contrary to what DrWPF.com stated in their example, do not put the ContentPresenter inside the RadioButton or else if you add an item with content such as a button or something else, you will not be able to set focus or interact with it. This technique solves that. Also, you need to handle the graying of the text as well as removing of margins on labels or else it will not render correctly. This style handles both for you as well.

<Style x:Key="RadioButtonListItem" TargetType="{x:Type ListBoxItem}" >

    <Setter Property="Template">
        <Setter.Value>

            <ControlTemplate TargetType="ListBoxItem">

                <DockPanel LastChildFill="True" Background="{TemplateBinding Background}" HorizontalAlignment="Stretch" VerticalAlignment="Center" >

                    <RadioButton IsChecked="{TemplateBinding IsSelected}" Focusable="False" IsHitTestVisible="False" VerticalAlignment="Center" Margin="0,0,4,0" />

                    <ContentPresenter
                        Content             = "{TemplateBinding ContentControl.Content}"
                        ContentTemplate     = "{TemplateBinding ContentControl.ContentTemplate}"
                        ContentStringFormat = "{TemplateBinding ContentControl.ContentStringFormat}"
                        HorizontalAlignment = "{TemplateBinding Control.HorizontalContentAlignment}"
                        VerticalAlignment   = "{TemplateBinding Control.VerticalContentAlignment}"
                        SnapsToDevicePixels = "{TemplateBinding UIElement.SnapsToDevicePixels}" />

                </DockPanel>

You now have the look and feel of radio buttons, but you can do two-way binding, and you can use an enumeration. Here's how...

<ListBox Style="{StaticResource RadioButtonList}"
    SelectedValue="{Binding SomeVal}"
    SelectedValuePath="Tag">

    <ListBoxItem Tag="{x:Static l:MyEnum.SomeOption}"     >Some option</ListBoxItem>
    <ListBoxItem Tag="{x:Static l:MyEnum.SomeOtherOption}">Some other option</ListBoxItem>
    <ListBoxItem Tag="{x:Static l:MyEnum.YetAnother}"     >Yet another option</ListBoxItem>

</ListBox>

Also, since we explicitly separated out the style that tragets the ListBoxItem rather than putting it inline, again as the other examples have shown, you can now create a new style off of it to customize things on a per-item basis such as spacing. (This will not work if you simply try to target ListBoxItem as the keyed style overrides generic control targets.)

Here's an example of putting a margin of 6 above and below each item. (Note how you have to explicitly apply the style via the ItemContainerStyle property and not simply targeting ListBoxItem in the ListBox's resource section for the reason stated above.)

<Window.Resources>
    <Style x:Key="SpacedRadioButtonListItem" TargetType="ListBoxItem" BasedOn="{StaticResource RadioButtonListItem}">
        <Setter Property="Margin" Value="0,6" />
    </Style>
</Window.Resources>

<ListBox Style="{StaticResource RadioButtonList}"
    ItemContainerStyle="{StaticResource SpacedRadioButtonListItem}"
    SelectedValue="{Binding SomeVal}"
    SelectedValuePath="Tag">

    <ListBoxItem Tag="{x:Static l:MyEnum.SomeOption}"     >Some option</ListBoxItem>
    <ListBoxItem Tag="{x:Static l:MyEnum.SomeOtherOption}">Some other option</ListBoxItem>
    <ListBoxItem Tag="{x:Static l:MyEnum.YetAnother}"     >Ter another option</ListBoxItem>

</ListBox>

Be very cautious about git rm .; it might remove more than you want. Of course, you can recover, but it is simpler not to have to do so.

Simplest would be:

git rm modules/welcome/language/english/kaimonokago_lang.php \
       modules/welcome/language/french/kaimonokago_lang.php \
       modules/welcome/language/german/kaimonokago_lang.php \
       modules/welcome/language/norwegian/kaimonokago_lang.php

You can't use shell wildcards because the files don't exist, but you could use (in Bash at least):

git rm modules/welcome/language/{english,french,german,norwegian}/kaimonokago_lang.php

Or consider:

git status | sed -n '/^# *deleted:/s///p' | xargs git rm

This takes the output of git status, doesn't print anything by default (sed -n), but on lines that start # deleted:, it gets rid of the # and the deleted: and prints what is left; xargs gathers up the arguments and provides them to a git rm command. This works for any number of files regardless of similarity (or dissimilarity) in the names.

I used the above references and complete solution is:-

Use Namespace System.Globalization;
string str="INFOA2Z means all information";

//Need result like "Infoa2z Means All Information"
//We need to convert the string in lowercase also, otherwise it is not working properly.

TextInfo ProperCase= new CultureInfo("en-US", false).TextInfo;

str= ProperCase.ToTitleCase(str.toLower());

Thanks for the answers. Now I know that there are two ways of "SAVE AS" in Vim.

Assumed that I'm editing hello.txt.

• :w world.txt will write hello.txt's content to the file world.txt while keeping hello.txt as the opened buffer in vim.
• :sav world.txt will first write hello.txt's content to the file world.txt, then close buffer hello.txt, finally open world.txt as the current buffer.

Consider the figure enclosed in this other question. ebp-4 is your first local variable and, seen as a dword pointer, it is the address of a 32 bit integer that has to be cleared. Maybe your source starts with

Object x = null;

Infinity is a reserved character in HTML. Following are its values in various forms.

• Hex : 8734
• Decimal : 221E
• Entity : ∞

To use in html code

<p>The html symbol is &#8734; </p>_x000D_
<p>The html symbol is &#x221E; </p>_x000D_
<p>The html symbol is &infin; </p>

whether you want to keep the aspect ratio of a video or stretch it to fill its parent area, using the right layout manager can get the job done.

Keep the aspect ratio :

<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">

<VideoView
  android:id="@+id/videoView"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:layout_gravity="center"/>

</LinearLayout>

!!! To fill in the field:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <VideoView android:id="@+id/videoViewRelative"
         android:layout_alignParentTop="true"
         android:layout_alignParentBottom="true"
         android:layout_alignParentLeft="true"
         android:layout_alignParentRight="true"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent">
    </VideoView>

</RelativeLayout>

<form>.WindowState = FormWindowState.Minimized;

I faced the same error when I used another class instead of component down the component decorator.

Component class must come just after the component decorator

  @Component({

 styleUrls: ['./smsgtrecon.component.css'],
 providers: [ChecklistDatabase]
 })


// THIS CAUSE ISSUE MOVE THIS UP TO COMPONENT DECORATOR
/**

 export class TodoItemNode {
 children: TodoItemNode[];
 item: string;
}


 export class SmsgtreconComponent implements OnInit {

After moving TodoItemNode to the top of component decorator it worked

The jQuery UI sortable feature includes a serialize method to do this. It's quite simple, really. Here's a quick example that sends the data to the specified URL as soon as an element has changes position.

$('#element').sortable({
    axis: 'y',
    update: function (event, ui) {
        var data = $(this).sortable('serialize');

        // POST to server using $.post or $.ajax
        $.ajax({
            data: data,
            type: 'POST',
            url: '/your/url/here'
        });
    }
});

What this does is that it creates an array of the elements using the elements id. So, I usually do something like this:

<ul id="sortable">
   <li id="item-1"></li>
   <li id="item-2"></li>
   ...
</ul>

When you use the serialize option, it will create a POST query string like this: item[]=1&item[]=2 etc. So if you make use - for example - your database IDs in the id attribute, you can then simply iterate through the POSTed array and update the elements' positions accordingly.

For example, in PHP:

$i = 0;

foreach ($_POST['item'] as $value) {
    // Execute statement:
    // UPDATE [Table] SET [Position] = $i WHERE [EntityId] = $value
    $i++;
}

Example on jsFiddle.

In your for loop you need to multiply the units * price. That gives you the total for that particular item. Also in the for loop you should add that to a counter that keeps track of the grand total. Your code would look something like

float total;
total += theItem.getUnits() * theItem.getPrice();

total should be scoped so it's accessible from within main unless you want to pass it around between function calls. Then you can either just print out the total or create a method that prints it out for you.

in your question, both buffer and byteArray seem to be byte[]. So:

ImageElement image = ImageElement.FromBinary(buffer);

Just to add to the other answers, the documentation gives this explanation:

• KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

• A UNIQUE index creates a constraint such that all values in the index must be distinct. An error occurs if you try to add a new row with a key value that matches an existing row. For all engines, a UNIQUE index permits multiple NULL values for columns that can contain NULL.

• A PRIMARY KEY is a unique index where all key columns must be defined as NOT NULL. If they are not explicitly declared as NOT NULL, MySQL declares them so implicitly (and silently). A table can have only one PRIMARY KEY. The name of a PRIMARY KEY is always PRIMARY, which thus cannot be used as the name for any other kind of index.

Binding events from html is NOT recommended. This is recommended way:

document.getElementById('btn').addEventListener('click', function(){
    pay();
    cls();
});

Just in case someone really needs a closure like that, it can be done in the following way:

var categoriesPerPage = [[Int]]()
var numPagesClosure: ()->Int {
    return {
        return self.categoriesPerPage.count
    }
}

Start the control panel using "Run as administrator". Then you can install Apache and MySQL as a service:

With primitives, it probably doesn't matter entirely which one you use. I say where it gets usefulness is when you want to output complex objects.

For example, if you have a class,

#include <iostream>
#include <cstdlib>

using namespace std;

class Something
{
public:
        Something(int x, int y, int z) : a(x), b(y), c(z) { }
        int a;
        int b;
        int c;

        friend ostream& operator<<(ostream&, const Something&);
};

ostream& operator<<(ostream& o, const Something& s)
{
        o << s.a << ", " << s.b << ", " << s.c;
        return o;
}

int main(void)
{
        Something s(3, 2, 1);

        // output with printf
        printf("%i, %i, %i\n", s.a, s.b, s.c);

        // output with cout
        cout << s << endl;

        return 0;
}

Now the above might not seem all that great, but let's suppose you have to output this in multiple places in your code. Not only that, let's say you add a field "int d." With cout, you only have to change it in once place. However, with printf, you'd have to change it in possibly a lot of places and not only that, you have to remind yourself which ones to output.

With that said, with cout, you can reduce a lot of times spent with maintenance of your code and not only that if you re-use the object "Something" in a new application, you don't really have to worry about output.

class Test
{
    Dictionary<int, string> entities;

    public string GetEntity(int code)
    {
        // java's get method returns null when the key has no mapping
        // so we'll do the same

        string val;
        if (entities.TryGetValue(code, out val))
            return val;
        else
            return null;
    }
}

Depends on if the form that the select is contained in has the method set to "get" or "post".

If <form method="get"> then the value of the select will be located in the super global array $_GET['taskOption'].

If <form method="post"> then the value of the select will be located in the super global array $_POST['taskOption'].

To store it into a variable you would:

$option = $_POST['taskOption']

A good place for more information would be the PHP manual: http://php.net/manual/en/tutorial.forms.php

Update 1: It is possible for different users to have different path. But its not the likely problem here. There is more chance that the user that the iwam user doesn't have permission to the oracle client directory.

Update 0: Its suppose to work. Check for environment variable ( That are needed to find the oracle client and tnsnames.ora ). Also, Maybe you have a 32/64 bit issues. Also, consider using the Oracle Data Provider for .NET ( search for odp.net)

Late to the conversation...

If you have the module installed and set your PHP.INI file properly, check your apache error log for something like the following:

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\php\ext\php_mysqli.dll' - The specified module could not be found.

In this case, your extension directory is not what you think it is. You may neeed to set it explicitly, like so:

extension_dir="C:\xampp\php\ext"

On app.module.ts add the following imports. There is a list of LOCALE options here.

import es from '@angular/common/locales/es';
import { registerLocaleData } from '@angular/common';
registerLocaleData(es);

Then add the provider

@NgModule({
  providers: [
    { provide: LOCALE_ID, useValue: "es-ES" }, //your locale
  ]
})

Use pipes in html. Here is the angular documentation for this.

There are a set of available properties to all Maven projects.

From Introduction to the POM:

project.basedir: The directory that the current project resides in.

This means this points to where your Maven projects resides on your system. It corresponds to the location of the pom.xml file. If your POM is located inside /path/to/project/pom.xml then this property will evaluate to /path/to/project.

Some properties are also inherited from the Super POM, which is the case for project.build.directory. It is the value inside the <project><build><directory> element of the POM. You can get a description of all those values by looking at the Maven model. For project.build.directory, it is:

The directory where all files generated by the build are placed. The default value is target.

This is the directory that will hold every generated file by the build.

The following code works on your example :

gsub(".*_", "", a)

When using Xcode 6 and it says

Waiting for make

It might be that an instance of make is already running. Kill the process and indexing proceeds. Silly, but worked for me.

You were just missing an image tag to change the "src" attribute of:

I've been integrating a lot of stuff into Python lately, including Java. The most robust method I've found is to use IKVM and a C# wrapper.

IKVM has a neat little application that allows you to take any Java JAR, and convert it directly to .Net DLL. It simply translates the JVM bytecode to CLR bytecode. See http://sourceforge.net/p/ikvm/wiki/Ikvmc/ for details.

The converted library behaves just like a native C# library, and you can use it without needing the JVM. You can then create a C# DLL wrapper project, and add a reference to the converted DLL.

You can now create some wrapper stubs that call the methods that you want to expose, and mark those methods as DllEport. See https://stackoverflow.com/a/29854281/1977538 for details.

The wrapper DLL acts just like a native C library, with the exported methods looking just like exported C methods. You can connect to them using ctype as usual.

I've tried it with Python 2.7, but it should work with 3.0 as well. Works on Windows and the Linuxes

If you happen to use C#, then this is probably the best approach to try when integrating almost anything into python.

 function uploadFile() {
     var fileElement = document.getElementById("fileToUpload");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension == "odx-d"||fileExtension == "odx"||fileExtension == "pdx"||fileExtension == "cmo"||fileExtension == "xml") {
         var fd = new FormData();
        fd.append("fileToUpload", document.getElementById('fileToUpload').files[0]);
        var xhr = new XMLHttpRequest();
        xhr.upload.addEventListener("progress", uploadProgress, false);
        xhr.addEventListener("load", uploadComplete, false);
        xhr.addEventListener("error", uploadFailed, false);
        xhr.addEventListener("abort", uploadCanceled, false);
        xhr.open("POST", "/post_uploadReq");
        xhr.send(fd);
        }
        else {
            alert("You must select a valid odx,pdx,xml or cmo file for upload");
            return false;
        }
       
      }

tried this , works very well

The problem with specifying non-grouped and non-aggregate fields in group by selects is that engine has no way of knowing which record's field it should return in this case. Is it first? Is it last? There is usually no record that naturally corresponds to aggregated result (min and max are exceptions).

However, there is a workaround: make the required field aggregated as well. In posgres, this should work:

SELECT cname, (array_agg(wmname ORDER BY avg DESC))[1], MAX(avg)
FROM makerar GROUP BY cname;

Note that this creates an array of all wnames, ordered by avg, and returns the first element (arrays in postgres are 1-based).

Making your own itoa is also easy, try this :

char* itoa(int i, char b[]){
    char const digit[] = "0123456789";
    char* p = b;
    if(i<0){
        *p++ = '-';
        i *= -1;
    }
    int shifter = i;
    do{ //Move to where representation ends
        ++p;
        shifter = shifter/10;
    }while(shifter);
    *p = '\0';
    do{ //Move back, inserting digits as u go
        *--p = digit[i%10];
        i = i/10;
    }while(i);
    return b;
}

or use the standard sprintf() function.

public static void main(String[] args) {
    int[] toyNumber = new int[] {5};
    NewClass temp = new NewClass();
    temp.play(toyNumber);
    System.out.println("Toy number in main " + toyNumber[0]);
}

void play(int[] toyNumber){
    System.out.println("Toy number in play " + toyNumber[0]);
    toyNumber[0]++;
    System.out.println("Toy number in play after increement " + toyNumber[0]);
}

git stash list to list your stashed changes.

Your syntax is wrong.

You need to call attr with two parameters, like this:

$('.salesperson', newOption).attr('defaultSelected', "selected");

Your current code assigns the value "selected" to the variable defaultSelected, then passes that value to the attr function, which will then return the value of the selected attribute.

A little intro to dictionary

d={'a':'apple','b':'ball'}
d.keys()  # displays all keys in list
['a','b']
d.values() # displays your values in list
['apple','ball']
d.items() # displays your pair tuple of key and value
[('a','apple'),('b','ball')

Print keys,values method one

for x in d.keys():
    print x +" => " + d[x]

Another method

for key,value in d.items():
    print key + " => " + value

You can get keys using iter

>>> list(iter(d))
['a', 'b']

You can get value of key of dictionary using get(key, [value]):

d.get('a')
'apple'

If key is not present in dictionary,when default value given, will return value.

d.get('c', 'Cat')
'Cat'

To ensure that the hex is always 40 characters long, the BigInteger has to be positive:

public String toHex(String arg) {
  return String.format("%x", new BigInteger(1, arg.getBytes(/*YOUR_CHARSET?*/)));
}

In my case, I need to dump the sql result into a file on the client side. This is the most typical use case to off load data from the database. In many situations, you don't have access to the server or don't want to write your result to the server.

mysql -h hostname -u username -ppwd -e "mysql simple sql statement that last for less than a line" DATABASE_NAME > outputfile_on_the.client

The problem comes when you have a complicated query that last for several lines; you cannot use the command line to dump the result to a file easily. In such cases, you can put your complicated query into a file, such as longquery_file.sql, then execute the command.

mysql -h hn -u un -ppwd < longquery_file.sql DBNAME > output.txt

This worked for me. The only difficulty with me is the tab character; sometimes I use for group_cancat(foo SEPARATOR 0x09) will be written as '\t' in the output file. The 0x09 character is ASCII TAB. But this problem is not particular to the way we dump sql results to file. It may be related to my pager. Let me know when you find an answer to this problem. I will update this post.

Add theme @style/Theme.AppCompat.Light.NoActionBar in your activity on AndroidManifest.xml like this

<activity
        android:name=".activities.MainActivity"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">
    </activity>

I hope I understand your question correctly: assuming that the values are of type String, the most efficient way is probably to convert to a HashSet and iterate over it:

ArrayList<String> values = ... //Your values
HashSet<String> uniqueValues = new HashSet<>(values);
for (String value : uniqueValues) {
   ... //Do something
}

Without Gradle (Click here for the Gradle solution)

1. Create a support library project.

2. Import your library project to Intellij from Eclipse project (this step only applies if you created your library in Eclipse).

3. Right click on module and choose Open Module Settings.

4. Setup libraries of v7 jar file

5. Setup library module of v7

6. Setup app module dependency of v7 library module

Use elevation to implement shadows on RN Android. Added elevation prop #27

    Console.Write(new string(' ', Console.WindowWidth)); 
    Console.SetCursorPosition(0, Console.CursorTop - 1);
}

Please find below the easy way :

XSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop((short) 6); // double lines border
style.setBorderBottom((short) 1); // single line border
XSSFFont font = workbook.createFont();
font.setFontHeightInPoints((short) 15);
font.setBoldweight(XSSFFont.BOLDWEIGHT_BOLD);
style.setFont(font);                 

Row row = sheet.createRow(0);   
Cell cell0 = row.createCell(0);
cell0.setCellValue("Nav Value");
cell0.setCellStyle(style);  
for(int j = 0; j<=3; j++)
row.getCell(j).setCellStyle(style);

Inherit Activity Class instead of ListActivity you can resolve this problem.

public class ExampleActivity extends Activity  {

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.mainlist);
    }
}

The accepted answer works but can got complicated when I wanted to try adding Accept headers. This is what I ended up with. It seems simpler to me so I think I'll stick with it in the future:

client.DefaultRequestHeaders.Add("Accept", "application/*+xml;version=5.1");
client.DefaultRequestHeaders.Add("Authorization", "Basic " + authstring);

I cobbled together a 'dynamic' struct class today, had a look tonight and someone has written something similar with better handling of constructor parameters, it might be worth a look:

http://code.activestate.com/recipes/577160-php-struct-port/

One of the comments on this page mentions an interesting thing in PHP - apparently you're able to cast an array as an object, which lets you refer to array elements using the arrow notation, as you would with a Struct pointer in C. The comment's example was as follows:

$z = array('foo' => 1, 'bar' => true, 'baz' => array(1,2,3));
//accessing values as properties
$y = (object)$z;
echo $y->foo;

I haven't tried this myself yet, but it may be that you could get the desired notation by just casting - if that's all you're after. These are of course 'dynamic' data structures, just syntactic sugar for accessing key/value pairs in a hash.

If you're actually looking for something more statically typed, then ASpencer's answer is the droid you're looking for (as Obi-Wan might say.)

http://en.wikipedia.org/wiki/Division_by_zero

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

If you look at the most recent update on Git's website in the "git via git" section you will see an option to update your older version.

Here is the command that git has on their site:

git clone https://github.com/git/git

It worked for my version of git which was a 2.13.0.windows.1.

By default, mysql search my.cnf first at /etc folder. If there is no /etc/my.cnf file inside this folder, I advise you to create new one in this folder as indicated by the documentation (https://dev.mysql.com/doc/refman/5.6/en/option-files.html).

You can also search for existing my.cnf furnished by your mysql installation. You can launch the following command

sudo find / -name "*.cnf"

You can use the following configuration file with myisam table and without innodb mysql support (from port installation of mysql on mac os x maverick). Please verify each command in this configuration file.

# Replication Slave (comment out master section to use this)
#
# To configure this host as a replication slave, you can choose between
# two methods :
#
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#
#    CHANGE MASTER TO MASTER_HOST=<host>, MASTER_PORT=<port>,
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#
#    Example:
#
#    CHANGE MASTER TO MASTER_HOST='125.564.12.1', MASTER_PORT=3306,
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
#
# OR
#
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)
#
# required unique id between 2 and 2^32 - 1
# (and different from the master)
# defaults to 2 if master-host is set
# but will not function as a slave if omitted
#server-id       = 2
#
# The replication master for this slave - required
#master-host     =   <hostname>
#
# The username the slave will use for authentication when connecting

# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
#
# The port the master is listening on.

Have you tried using JavaScriptSerializer ? There's also DataContractJsonSerializer

You are correct here:

Integer i = 0;
i = i + 1;  // <- I think that this is somehow creating a new object!

First: Integer is immutable.

Second: the Integer class is not overriding the + operator, there is autounboxing and autoboxing involved at that line (In older versions of Java you would get an error on the above line).
When you write i + 1 the compiler first converts the Integer to an (primitive) int for performing the addition: autounboxing. Next, doing i = <some int> the compiler converts from int to an (new) Integer: autoboxing.
So + is actually being applied to primitive ints.

try this

I had to add the ?wsdl parameter to the end of the url. For example: http://localhost:8745/YourServiceName/?wsdl

The only reason that the linter complains about using setState({..}) in componentDidMount and componentDidUpdate is that when the component render the setState immediately causes the component to re-render. But the most important thing to note: using it inside these component's lifecycles is not an anti-pattern in React.

Please take a look at this issue. you will understand more about this topic. Thanks for reading my answer.

TL;DR Use Cmd/Ctrl+Shift+P then Package Control: Install Package, then Print to HTML and install it. Use Alt+Shift+P to print.

My favorite tool for printing from Sublime Text is Print to HTML package. You can "print" a selection or a whole file - via the web browser.

Usage

1. Make a selection (or none for the whole file)
2. Press Alt+Shift+P OR Shift+Command+P and type in "Print to HTML".

This opens your browser print dialog (Chrome for me) with the selected text neatly in the print dialog window and syntax highlighting intact. There you can choose a printer or export to PDF, and print.

Setup

Install the "Print to HTML" package using the package manager.

1. Ctrl + Shift + P => Gives a list of commands.
2. Find the package manager by typing "install"
3. You see a few choices. Select "Package Control: Install Package"
4. This opens a list of packages. Type "print to"
5. One of the choices should be "Print to HTML". Select that, and it is being installed.
6. You can use the "print to html" now by a keyboard shortcut Alt+Shift+P

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }

let layout = myCollectionView.collectionViewLayout as? UICollectionViewFlowLayout

I've written a fairly comprehensive article about this very topic and also developed a pop-in library for MVVM Dialogs. Strict adherence to MVVM is not only possible but very clean when implemented properly, and it can be easily extended to third-party libraries that don't adhere to it themselves:

https://www.codeproject.com/Articles/820324/Implementing-Dialog-Boxes-in-MVVM

Empty is a subset of any string.

Think of them as what is between every two characters.

Kind of the way there are an infinite number of points on any sized line...

(Hmm... I wonder what I would get if I used calculus to concatenate an infinite number of empty strings)

Note that "".equals("") only though.

Check out the language reference:

Sounds like you are using Microsoft Visual C++. If that is the case, then the most possibility is that you don't compile your two.cpp with one.cpp (one.cpp is the implementation for one.h).

If you are from command line (cmd.exe), then try this first: cl -o two.exe one.cpp two.cpp

If you are from IDE, right click on the project name from Solution Explore. Then choose Add, Existing Item.... Add one.cpp into your project.

What I did was to create a canvas element that I then position in front of the image map. Then, whenever an area is moused-over, I call a func that gets the coord string for that shape and the shape-type. If it's a poly I use the coords to draw an outline on the canvas. If it's a rect I draw a rect outline. You could easily add code to deal with circles.

You could also set the opacity of the canvas to less than 100% before filling the poly/rect/circle. You could also change the reliance on a global for the canvas's context - this would mean you could deal with more than 1 image-map on the same page.

It doesn't take the 50% of the whole page is because the "whole page" is only how tall your contents are. Change the enclosing html and body to 100% height and it will work.

html, body{
    height: 100%;
}
div{
    height: 50%;
}

http://jsfiddle.net/DerekL/5YukJ/1/

^ Your document is only 20px high. 50% of 20px is 10px, and it is not what you expected.

^ Now if you change the height of the document to the height of the whole page (150px), 50% of 150px is 75px, then it will work.

Just pure history. Quote from Stan Lippman:

The reason for the two keywords is historical. In the original template specification, Stroustrup reused the existing class keyword to specify a type parameter rather than introduce a new keyword that might of course break existing programs. It wasn't that a new keyword wasn't considered -- just that it wasn't considered necessary given its potential disruption. And up until the ISO-C++ standard, this was the only way to declare a type parameter.

But one should use typename rather than class! See the link for more info, but think about the following code:

template <class T>
class Demonstration { 
public:
void method() {
   T::A *aObj; // oops ...
};

I've solved using only @JsonIgnore like @kryger has suggested. So your getter will become:

@JsonIgnore
public String getEncryptedPwd() {
    return this.encryptedPwd;
}

You can set @JsonIgnore of course on field, setter or getter like described here.

And, if you want to protect encrypted password only on serialization side (e.g. when you need to login your users), add this @JsonProperty annotation to your field:

@JsonProperty(access = Access.WRITE_ONLY)
private String encryptedPwd;

More info here.

Yes, a static class can have static constructor, and the use of this constructor is initialization of static member.

static class Employee1
{
    static int EmpNo;
    static Employee1()
    {
        EmpNo = 10;
        // perform initialization here
    }
    public static void Add()
    { 

    }
    public static void Add1()
    { 

    }
}

and static constructor get called only once when you have access any type member of static class with class name Class1

Suppose you are accessing the first EmployeeName field then constructor get called this time, after that it will not get called, even if you will access same type member.

 Employee1.EmployeeName = "kumod";
        Employee1.Add();
        Employee1.Add();

I found the answer here: http://blog.sqlauthority.com/2007/08/22/sql-server-t-sql-script-to-insert-carriage-return-and-new-line-feed-in-code/

You just concatenate the string and insert a CHAR(13) where you want your line break.

Example:

DECLARE @text NVARCHAR(100)
SET @text = 'This is line 1.' + CHAR(13) + 'This is line 2.'
SELECT @text

This prints out the following:

This is line 1.
This is line 2.

You can rewrite the code likes this:

#include<iostream>
#include<stdio.h>

using namespace std;

Just a speculation, I have not enough experience to try it... )-:

Since GoogleMap is a fragment, it should be possible to catch marker onClick event and show custom fragment view. A map fragment will be still visible on the background. Does anybody tried it? Any reason why it could not work?

The disadvantage is that map fragment would be freezed on backgroud, until a custom info fragment return control to it.

For the async Method ("ExecuteSqlCommandAsync") you can use it like this:

var sql = @"Update [User] SET FirstName = @FirstName WHERE Id = @Id";

await ctx.Database.ExecuteSqlCommandAsync(
    sql,
    parameters: new[]{
        new SqlParameter("@FirstName", firstname),
        new SqlParameter("@Id", id)
    });

While this question was asked about SQL Server 2005, it's worth noting that as of Sql Server 2017, the request can be done with the new TRANSLATE function.

https://docs.microsoft.com/en-us/sql/t-sql/functions/translate-transact-sql

I hope this information helps people who get to this page in the future.

After you commit your object into the db the object receives a value in its ID field.

So:

myObject.Field1 = "value";

// Db is the datacontext
db.MyObjects.InsertOnSubmit(myObject);
db.SubmitChanges();

// You can retrieve the id from the object
int id = myObject.ID;

Despite setting up dimensions for the columns, they still seem to shrink as the window shrinks.

An initial setting of a flex container is flex-shrink: 1. That's why your columns are shrinking.

It doesn't matter what width you specify (it could be width: 10000px), with flex-shrink the specified width can be ignored and flex items are prevented from overflowing the container.

I'm trying to set up a flexbox with 3 columns where the left and right columns have a fixed width...

You will need to disable shrinking. Here are some options:

.left, .right {
     width: 230px;
     flex-shrink: 0;
 }  

OR

.left, .right {
     flex-basis: 230px;
     flex-shrink: 0;
}

OR, as recommended by the spec:

.left, .right {
    flex: 0 0 230px;    /* don't grow, don't shrink, stay fixed at 230px */
}

7.2. Components of Flexibility

Authors are encouraged to control flexibility using the flex shorthand rather than with its longhand properties directly, as the shorthand correctly resets any unspecified components to accommodate common uses.

More details here: What are the differences between flex-basis and width?

An additional thing I need to do is hide the right column based on user interaction, in which case the left column would still keep its fixed width, but the center column would fill the rest of the space.

Try this:

.center { flex: 1; }

This will allow the center column to consume available space, including the space of its siblings when they are removed.

Revised Fiddle

I had to use os.system, since subprocess was giving me a memory error for larger tasks. Reference for this problem here. So, in order to get the output of the os.system command I used this workaround:

import os

batcmd = 'dir'
result_code = os.system(batcmd + ' > output.txt')
if os.path.exists('output.txt'):
    fp = open('output.txt', "r")
    output = fp.read()
    fp.close()
    os.remove('output.txt')
    print(output)

As you say, this is strictly undefined behaviour, though it will "work" on many platforms. The real reason for using unions is to create variant records.

union A {
   int i;
   double d;
};

A a[10];    // records in "a" can be either ints or doubles 
a[0].i = 42;
a[1].d = 1.23;

Of course, you also need some sort of discriminator to say what the variant actually contains. And note that in C++ unions are not much use because they can only contain POD types - effectively those without constructors and destructors.

I know it's been a while but I've been working on an npm package for private and public routes.

Here's how to make a private route:

<PrivateRoute exact path="/private" authed={true} redirectTo="/login" component={Title} text="This is a private route"/>

And you can also make Public routes that only unauthed user can access

<PublicRoute exact path="/public" authed={false} redirectTo="/admin" component={Title} text="This route is for unauthed users"/>

I hope it helps!

Try this as break;

angular.forEach([0,1,2], function(count){
  if(count == 1){
    return true;
  }
});

Using jquery you might do something like this:

// To disable 
$('#targetDiv').children().attr('disabled', 'disabled');

// To enable
$('#targetDiv').children().attr('enabled', 'enabled');

Here's a jsFiddle example: http://jsfiddle.net/monknomo/gLukqygq/

You could also select the target div's children and add a "disabled" css class to them with different visual properties as a callout.

//disable by adding disabled class
$('#targetDiv').children().addClass("disabled");

//enable by removing the disabled class
$('#targetDiv').children().removeClass("disabled");

Here's a jsFiddle with the as an example: https://jsfiddle.net/monknomo/g8zt9t3m/

All these answers date back to 2016 or earlier... There's a new web standard for this using flex-boxes. In general floats for these sorts of problems is now frowned upon.

Previous answer is obsolete. It's possible to achieve in one step since Laravel 5.3, firstOrCreate now has second parameter values, which is being used for new record, but not for search

$user = User::firstOrCreate([
    'email' => '[email protected]'
], [
    'firstName' => 'Taylor',
    'lastName' => 'Otwell'
]);

To anyone interested, here's a class I created using inazaruk's code that creates everything needed (I called it UIUpdater because I use it to periodically update the UI, but you can call it anything you like):

import android.os.Handler;
/**
 * A class used to perform periodical updates,
 * specified inside a runnable object. An update interval
 * may be specified (otherwise, the class will perform the 
 * update every 2 seconds).
 * 
 * @author Carlos Simões
 */
public class UIUpdater {
        // Create a Handler that uses the Main Looper to run in
        private Handler mHandler = new Handler(Looper.getMainLooper());

        private Runnable mStatusChecker;
        private int UPDATE_INTERVAL = 2000;

        /**
         * Creates an UIUpdater object, that can be used to
         * perform UIUpdates on a specified time interval.
         * 
         * @param uiUpdater A runnable containing the update routine.
         */
        public UIUpdater(final Runnable uiUpdater) {
            mStatusChecker = new Runnable() {
                @Override
                public void run() {
                    // Run the passed runnable
                    uiUpdater.run();
                    // Re-run it after the update interval
                    mHandler.postDelayed(this, UPDATE_INTERVAL);
                }
            };
        }

        /**
         * The same as the default constructor, but specifying the
         * intended update interval.
         * 
         * @param uiUpdater A runnable containing the update routine.
         * @param interval  The interval over which the routine
         *                  should run (milliseconds).
         */
        public UIUpdater(Runnable uiUpdater, int interval){
            UPDATE_INTERVAL = interval;
            this(uiUpdater);
        }

        /**
         * Starts the periodical update routine (mStatusChecker 
         * adds the callback to the handler).
         */
        public synchronized void startUpdates(){
            mStatusChecker.run();
        }

        /**
         * Stops the periodical update routine from running,
         * by removing the callback.
         */
        public synchronized void stopUpdates(){
            mHandler.removeCallbacks(mStatusChecker);
        }
}

You can then create a UIUpdater object inside your class and use it like so:

...
mUIUpdater = new UIUpdater(new Runnable() {
         @Override 
         public void run() {
            // do stuff ...
         }
    });

// Start updates
mUIUpdater.startUpdates();

// Stop updates
mUIUpdater.stopUpdates();
...

If you want to use this as an activity updater, put the start call inside the onResume() method and the stop call inside the onPause(), so the updates start and stop according to the activity visibility.

You can use android:stopWithTask="false"in manifest as bellow, This means even if user kills app by removing it from tasklist, your service won't stop.

 <service android:name=".service.StickyService"
                  android:stopWithTask="false"/>

Don't use spaces...
