You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }
}

(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)

Try using String.getBytes(). It returns a byte[] representing string data. Example:

String data = "sample data";
byte[] byteData = data.getBytes();

This is because of

String outStr = obj.toString("UTF-8");

Send the byte[] which you can get from your ByteArrayOutputStream and use it as such in your ByteArrayInputStream to construct your GZIPInputStream. Following are the changes which need to be done in your code.

byte[] compressed = compress(string); //In the main method

public static byte[] compress(String str) throws Exception {
    ...
    ...
    return obj.toByteArray();
}

public static String decompress(byte[] bytes) throws Exception {
    ...
    GZIPInputStream gis = new GZIPInputStream(new ByteArrayInputStream(bytes));
    ...
}

Because of the condition in while, the loop might never break:

while (entry != null) {
  // If entry never becomes null here, loop will never break.
}

Instead of the null check there, you can try this:

ZipEntry entry = null;
while ((entry = zip.getNextEntry()) != null) {
  // Rest of your code
}

The basic setup of decorators is like this:

InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);

The key issue in this snippet is the value of encoding. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.

For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.

Most network protocols use a header or other metadata to explicitly note the character encoding.

In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.

Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!

I'm currently using SDK 20.0.3 and none of the previous solutions worked for me.

The reason that hessdroid works where hess failed is because the two jar files contain java that is compiled for different virtual machines. The byte code created by the Java compiler is not guaranteed to run on the Dalvik virtual machine. The byte code created by the Android compiler is not guaranteed to run on the Java virtual machine.

In my case I had access to the source code and was able to create an Android jar file for it using the method that I described here: https://stackoverflow.com/a/13144382/545064

Here's an example update trigger:

create table Employees (id int identity, Name varchar(50), Password varchar(50))
create table Log (id int identity, EmployeeId int, LogDate datetime, 
    OldName varchar(50))
go
create trigger Employees_Trigger_Update on Employees
after update
as
insert into Log (EmployeeId, LogDate, OldName) 
select id, getdate(), name
from deleted
go
insert into Employees (Name, Password) values ('Zaphoid', '6')
insert into Employees (Name, Password) values ('Beeblebox', '7')
update Employees set Name = 'Ford' where id = 1
select * from Log

This will print:

id   EmployeeId   LogDate                   OldName
1    1            2010-07-05 20:11:54.127   Zaphoid

href is optional for a elements.

It's completely sufficient to use

<a onclick="ShowOld(2367,146986,2)">link text</a>

Had the same problem with different casing.

Did a checkout to development (or master) then changed the name (the wrong name) to something else like test.

• git checkout development
• git branch -m wrong-name test

then change the name back to the right name

• git branch -m test right-name

then checkout to the right-name branch

• git checkout right-name

then it worked to push to the remote branch

• git push origin right-name

I wrote an extension method of DataRow which gets me the object via the column name.

public static object Column(this DataRow source, string columnName)
{
    var c = source.Table.Columns[columnName];
    if (c != null)
    {
        return source.ItemArray[c.Ordinal];
    }

    throw new ObjectNotFoundException(string.Format("The column '{0}' was not found in this table", columnName));
}

And its called like this:

DataTable data = LoadDataTable();
foreach (DataRow row in data.Rows)
{        
    var obj = row.Column("YourColumnName");
    Console.WriteLine(obj);
}

Your #container should be outside of the #header-wrap, then specify a fixed height for #header-wrap, after, specify margin-top for #container equal to the #header-wrap's height. Something like this:

#header-wrap {
    position: fixed;
    height: 200px;
    top: 0;
    width: 100%;
    z-index: 100;
}
#container{ 
    margin-top: 200px;
}

The simplest answer would be to convert the required values to binary, and see how many bits are required for that value. However, the question asks how many bits for a decimal number of X digits. In this case, it seems like you have to choose the highest value with X digits, and then convert that number to binary.

As a basic example, Let's assume we wanted to store a 1 digit base ten number, and wanted to know how many bits that would require. The largest 1 digit base ten number is 9, so we need to convert it to binary. This yields 1001, which has a total of 4 bits. This same example can be applied to a two digit number (with the max value being 99, which converts to 1100011). To solve for n digits, you probably need to solve the others and search for a pattern.

To convert values to binary, you repeatedly divide by two until you get a quotient of 0 (and all of your remainders will be 0 or 1). You then reverse the orders of your remainders to get the number in binary.

Exampe: 13 to binary.

• 13/2 = 6 r 1
• 6/2 = 3 r 0
• 3/2 = 1 r 1
• 1/2 = 0 r 1
• = 1101 ((8*1) + (4*1) + (2*0) + (1*1))

Hope this helps out.

This script works!

#/bin/bash
if [[ ( "$#" < 1 ) || ( !( "$1" == 1 ) && !( "$1" == 0 ) ) ]] ; then
    echo this script requires a 1 or 0 as first parameter.
else
    echo "first parameter is $1"
    xinput set-prop 12 "Device Enabled" $0
fi

But this also works, and in addition keeps the logic of the OP, since the question is about calculations. Here it is with only arithmetic expressions:

#/bin/bash
if (( $# )) && (( $1 == 0 || $1 == 1 )); then
    echo "first parameter is $1"
    xinput set-prop 12 "Device Enabled" $0
else
    echo this script requires a 1 or 0 as first parameter.
fi

The output is the same¹:

$ ./tmp.sh 
this script requires a 1 or 0 as first parameter.

$ ./tmp.sh 0
first parameter is 0

$ ./tmp.sh 1
first parameter is 1

$ ./tmp.sh 2
this script requires a 1 or 0 as first parameter.

_{[1] the second fails if the first argument is a string}

If you want it visually formatted to two decimals as a string (for output) use toFixed():

var priceString = someValue.toFixed(2);

The answer by @David has two problems:

1. It leaves the result as a floating point number, and consequently holds the possibility of displaying a particular result with many decimal places, e.g. 134.1999999999 instead of "134.20".

2. If your value is an integer or rounds to one tenth, you will not see the additional decimal value:

   var n = 1.099;
   (Math.round( n * 100 )/100 ).toString() //-> "1.1"
   n.toFixed(2)                            //-> "1.10"
   
   var n = 3;
   (Math.round( n * 100 )/100 ).toString() //-> "3"
   n.toFixed(2)                            //-> "3.00"
   

And, as you can see above, using toFixed() is also far easier to type. ;)

You can remove unwanted menu items in Page_Load, like this:

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Roles.IsUserInRole("Admin"))
        {
            MenuItemCollection menuItems = mTopMenu.Items;
            MenuItem adminItem = new MenuItem();
            foreach (MenuItem menuItem in menuItems)
            {
                if (menuItem.Text == "Roles")
                    adminItem = menuItem;
            }
            menuItems.Remove(adminItem);
        }
    }

I'm sure there's a neater way to find the right item to remove, but this one works. You could also add all the wanted menu items in a Page_Load method, instead of adding them in the markup.

I stumbled over the situation where the list might be empty. In that case:

os.path.join('', *the_list_with_path_components)

Note the first argument, which will not alter the result.

Use commas to separate case

switch (pageid)
{
    case "listing-page","home-page":
        alert("hello");
        break;
    case "details-page":
        alert("goodbye");
        break;
}

It would be this

array=($(ls -d */))

EDIT: See Gordon Davisson's solution for a more general answer (i.e. if your filenames contain special characters). This answer is merely a syntax correction.

Use forEach in combo with Object.entries().

const WALLPAPERS = [{
  WALLPAPER_KEY: 'wallpaper.image',
  WALLPAPER_VALID_KEY: 'wallpaper.image.valid',
}, {
  WALLPAPER_KEY: 'lockscreen.image',
  WALLPAPER_VALID_KEY: 'lockscreen.image.valid',
}];

WALLPAPERS.forEach((obj) => {
  for (const [key, value] of Object.entries(obj)) {
    console.log(`${key} - ${value}`);
  }
});

How to Use TempTable in Stored Procedure?

Here are the steps:

CREATE TEMP TABLE

-- CREATE TEMP TABLE 
Create Table #MyTempTable (
    EmployeeID int
);

INSERT TEMP SELECT DATA INTO TEMP TABLE

-- INSERT COMMON DATA
Insert Into #MyTempTable
Select EmployeeID from [EmployeeMaster] Where EmployeeID between 1 and 100

SELECT TEMP TABLE (You can now use this select query)

Select EmployeeID from #MyTempTable

FINAL STEP DROP THE TABLE

Drop Table #MyTempTable

I hope this will help. Simple and Clear :)

You could try to do it in this way.

for u in session.query(User).all():
    print(u._asdict())

After two dozens of comments to understand the situation, it was found that the libhdf5.so.7 was actually a symlink (with several levels of indirection) to a file that was not shared between the queued processes and the interactive processes. This means even though the symlink itself lies on a shared filesystem, the contents of the file do not and as a result the process was seeing different versions of the library.

For future reference: other than checking LD_LIBRARY_PATH, it's always a good idea to check a library with nm -D to see if the symbols actually exist. In this case it was found that they do exist in interactive mode but not when run in the queue. A quick md5sum revealed that the files were actually different.

You might be looking for IgnoreDataMemberAttribute.

Mutable means that it can change/mutate. Immutable the opposite.

Some Python data types are mutable, others not.

Let's find what are the types that fit in each category and see some examples.

Mutable

In Python there are various mutable types:

• lists

• dict

• set

Let's see the following example for lists.

list = [1, 2, 3, 4, 5]

If I do the following to change the first element

list[0] = '!'
#['!', '2', '3', '4', '5']

It works just fine, as lists are mutable.

If we consider that list, that was changed, and assign a variable to it

y = list

And if we change an element from the list such as

list[0] = 'Hello'
#['Hello', '2', '3', '4', '5']

And if one prints y it will give

['Hello', '2', '3', '4', '5']

As both list and y are referring to the same list, and we have changed the list.

Immutable

In some programming languages one can define a constant such as the following

const a = 10

And if one calls, it would give an error

a = 20

However, that doesn't exist in Python.

In Python, however, there are various immutable types:

• None

• bool

• int

• float

• str

• tuple

Let's see the following example for strings.

Taking the string a

a = 'abcd'

We can get the first element with

a[0]
#'a'

If one tries to assign a new value to the element in the first position

a[0] = '!'

It will give an error

'str' object does not support item assignment

When one says += to a string, such as

a += 'e'
#'abcde'

It doesn't give an error, because it is pointing a to a different string.

It would be the same as the following

a = a + 'f'

And not changing the string.

Some Pros and Cons of being immutable

• The space in memory is known from the start. It would not require extra space.

• Usually, it makes things more efficiently. Finding, for example, the len() of a string is much faster, as it is part of the string object.

How about:

WHERE LEFT(job_no, 4) IN ('0711', '0712', ...)

Most answers here will work fine if you have just two conditions in your if-else. For more which is I guess what you want, you'll be using arrays. Every names corresponding element in names array you'll have an element in the hasNames array with the exact same index. Then it's a matter of these four lines.

names = "true";
var names = ["true","false","1","2"];
var hasNames = ["Y","N","true","false"];
var intIndex = names.indexOf(name);
hasName = hasNames[intIndex ];

This method could also be implemented using Objects and properties as illustrated by Benjamin.

I think this is pretty obvious :

• $observe is used in linking function of directives.
• $watch is used on scope to watch any changing in its values.

Keep in mind : both the function has two arguments,

$observe/$watch(value : string, callback : function);

• value : is always a string reference to the watched element (the name of a scope's variable or the name of the directive's attribute to be watched)
• callback : the function to be executed of the form function (oldValue, newValue)

I have made a plunker, so you can actually get a grasp on both their utilization. I have used the Chameleon analogy as to make it easier to picture.

This should work

SELECT EXTRACTVALUE(column_name, '/DCResponse/ContextData/Decision') FROM traptabclob;

I have assumed the ** were just for highlighting?

As the databinding is out I'd like to share my solution for databinding TextViews supporting html tags with clickable links.

To avoid retrieving every textview and giving them html support using From.html we extend the TextView and put the logic in setText()

public class HtmlTextView extends TextView {

    public HtmlTextView(Context context) {
        super(context);
    }

    public HtmlTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public HtmlTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        super.setText(Html.fromHtml(text.toString()), type);
        this.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

I've made a gist which also shows example entity and view for using this.

<script type="text/javascript">
function report(func)
{
    func();
}

function daily()
{
    alert('daily');
}

function monthly()
{
    alert('monthly');
}
</script>

here is working code.

Now if you paste above code. you will see following result on your device.

I had the same problem when trying to run npm on system emulated in Oracle VirtualBox. I resolved it by adding Google DNS address in Network Adapter properties.

Network Adapter properties > IPv4 properties > Preferred DNS address: 8.8.8.8.

<context:component-scan base-package="" /> 

tells Spring to scan those packages for Annotations.

<mvc:annotation-driven> 

registers a RequestMappingHanderMapping, a RequestMappingHandlerAdapter, and an ExceptionHandlerExceptionResolver to support the annotated controller methods like @RequestMapping, @ExceptionHandler, etc. that come with MVC.

This also enables a ConversionService that supports Annotation driven formatting of outputs as well as Annotation driven validation for inputs. It also enables support for @ResponseBody which you can use to return JSON data.

You can accomplish the same things using Java-based Configuration using @ComponentScan(basePackages={"...", "..."} and @EnableWebMvc in a @Configuration class.

Check out the 3.1 documentation to learn more.

The simple way is to create table as textfile and move the file to the appropriate location

CREATE EXTERNAL TABLE mytable(col1 string, col2 string)
row format delimited fields terminated by '|' stored as textfile;

Copy the file to the HDFS Location where table is created.
Hope this helps!!!

For me, this helped: 1. Configuration properties/General/Platform Toolset = Windows XP (V110_xp) 2. C/C++ Preprocessor definitions, add "WIN32" 3. Linker/System/Minimum required version = 5.01

You just need to wrap object in ()

var arr = [{_x000D_
  id: 1,_x000D_
  name: 'bill'_x000D_
}, {_x000D_
  id: 2,_x000D_
  name: 'ted'_x000D_
}]_x000D_
_x000D_
var result = arr.map(person => ({ value: person.id, text: person.name }));_x000D_
console.log(result)

Heads up, if clearing the settings doesn't fix your issue you may need to uninstall the extensions as well.

The Best way is do not use any pairing code. Instead of onClick go to other function or other class where You create the socket using UUID.
Android automatically pops up for pairing if already not paired.

or see this link for better understanding

Below is code for the same:

private OnItemClickListener mDeviceClickListener = new OnItemClickListener() {
    public void onItemClick(AdapterView<?> av, View v, int arg2, long arg3) {
        // Cancel discovery because it's costly and we're about to connect
        mBtAdapter.cancelDiscovery();

        // Get the device MAC address, which is the last 17 chars in the View
        String info = ((TextView) v).getText().toString();
        String address = info.substring(info.length() - 17);

        // Create the result Intent and include the MAC address
        Intent intent = new Intent();
        intent.putExtra(EXTRA_DEVICE_ADDRESS, address);

        // Set result and finish this Activity
        setResult(Activity.RESULT_OK, intent);

      // **add this 2 line code** 
       Intent myIntent = new Intent(view.getContext(), Connect.class);
        startActivityForResult(myIntent, 0);

        finish();
    }

If you're compiling and exporting your apk file under SDK version 2.1, it will not work on any android version below your SDK export "2.1". Android software is forward compatible not backward compatible. For example if you're programming using the android NDK (ann add-on to the android SDK) package that allows development in the C/C++ family, this is only compatible with android 2.3, android version 2.2 and below support java builds only. Therefore you will reaceive the "There is a problem parsing the package" error.

If it happens in Chrome version > 45.x,

(1) try: System | Settings | Advanced settings
     uncheck "Use hardware acceleration when available", restart chrome.

(2) If (1) doesn't help, restart your computer

(3) If the black screen still occurs, try Chrome Cleanup Tool to reset your chrome.

I think this suits perfect for any color you have:

a {
    color: inherit;
}

look at last one

t = pd.DataFrame({'a': range(0, 10000), 'b': range(10000, 20000)})
B = []
C = []
A = time.time()
for i,r in t.iterrows():
    C.append((r['a'], r['b']))
B.append(round(time.time()-A,5))

C = []
A = time.time()
for ir in t.itertuples():
    C.append((ir[1], ir[2]))    
B.append(round(time.time()-A,5))

C = []
A = time.time()
for r in zip(t['a'], t['b']):
    C.append((r[0], r[1]))
B.append(round(time.time()-A,5))

C = []
A = time.time()
for r in range(len(t)):
    C.append((t.loc[r, 'a'], t.loc[r, 'b']))
B.append(round(time.time()-A,5))

C = []
A = time.time()
[C.append((x,y)) for x,y in zip(t['a'], t['b'])]
B.append(round(time.time()-A,5))
B

you have to call it like this

SELECT dbo.CheckIfSFExists(23, default)

From Technet:

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called in order to retrieve the default value. This behaviour is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value. An exception to this behaviour is when invoking a scalar function by using the EXECUTE statement. When using EXECUTE, the DEFAULT keyword is not required.

It'll have the same behavior as the underlying recv libc call see the man page for an official description of behavior (or read a more general description of the sockets api).

if you datatype is datetime of the table.col , then database store data contain two partial : 1 (date) 2 (time)

Just in display data use convert or cast.

Example:

create table #test(part varchar(10),lastTime datetime)
go

insert into #test (part ,lastTime )
values('A','2012-11-05 ')

insert into #test (part ,lastTime )
values('B','2012-11-05 10:30')


go

select * from #test 

A   2012-11-05 00:00:00.000
B   2012-11-05 10:30:00.000

select part,CONVERT (varchar,lastTime,111) from #test

A   2012/11/05
B   2012/11/05

select part,CONVERT (varchar(10),lastTime,20) from #test 

A   2012-11-05
B   2012-11-05

I would like to add something to the previous answers but since I don't have the rep to comment, I will just add an answer. This is directed towards android users which are programming in Java.

Per the post from RollingBoy, this code almost worked for me:

Process process = Runtime.getRuntime().exec("tasklist");
BufferedReader reader =
new BufferedReader(new InputStreamReader(process.getInputStream()));
while ((reader.readLine()) != null) {}
process.waitFor();

In my case, the waitFor() was not releasing because I was executing a statement with no return ("ip adddr flush eth0"). An easy way to fix this is to simply ensure you always return something in your statement. For me, that meant executing the following: "ip adddr flush eth0 && echo done". You can read the buffer all day, but if there is nothing ever returned, your thread will never release its wait.

Hope that helps someone!

The answer marked is perfect but for one scenario, where in the dd and mm are actually single digits. the following regex is perfect in this case:

    function validateDate(testdate) {_x000D_
        var date_regex = /^(0?[1-9]|1[0-2])\/(0?[1-9]|1\d|2\d|3[01])\/(19|20)\d{2}$/ ;_x000D_
        return date_regex.test(testdate);_x000D_
    }

Just a matter of the right google search:

data = dat_1.append(dat_2)
data = data.groupby(data.index).sum()

Easier to understand is like this:

String s = "a,b,c,d,e";
String[] sArr = s.split(",");
List<String> sList = Arrays.asList(sArr);

Here's a bash shell script I created to make Laravel 5 facades very quickly.

Run this in your Laravel 5 installation directory.

Call it like this:

make_facade.sh -f <facade_name> -n '<namespace_prefix>'

Example:

make_facade.sh -f helper -n 'App\MyApp'

If you run that example, it will create the directories Facades and Providers under 'your_laravel_installation_dir/app/MyApp'.

It will create the following 3 files and will also output them to the screen:

./app/MyApp/Facades/Helper.php
./app/MyApp/Facades/HelperFacade.php
./app/MyApp/Providers/HelperServiceProvider.php

After it is done, it will display a message similar to the following:

===========================
    Finished
===========================

Add these lines to config/app.php:
----------------------------------
Providers: App\MyApp\Providers\HelperServiceProvider,
Alias: 'Helper' => 'App\MyApp\Facades\HelperFacade',

So update the Providers and Alias list in 'config/app.php'

Run composer -o dumpautoload

The "./app/MyApp/Facades/Helper.php" will originally look like this:

<?php

namespace App\MyApp\Facades;


class Helper
{
    //
}

Now just add your methods in "./app/MyApp/Facades/Helper.php".

Here is what "./app/MyApp/Facades/Helper.php" looks like after I added a Helper function.

<?php

namespace App\MyApp\Facades;

use Request;

class Helper
{
    public function isActive($pattern = null, $include_class = false)
    {
        return ((Request::is($pattern)) ? (($include_class) ? 'class="active"' : 'active' ) : '');
    }
}

This is how it would be called:
===============================

{!!  Helper::isActive('help', true) !!}

This function expects a pattern and can accept an optional second boolean argument.

If the current URL matches the pattern passed to it, it will output 'active' (or 'class="active"' if you add 'true' as a second argument to the function call).

I use it to highlight the menu that is active.

Below is the source code for my script. I hope you find it useful and please let me know if you have any problems with it.

#!/bin/bash

Go to the traffic section inside graphs. Here you can find how many unique visitors you have. Other than this there is no other way to know who exactly viewed your account.

iOS 11 , Swift 4
And you can try this code:

if #available(iOS 11.0, *) {
   element.clipsToBounds = true
   element.layer.cornerRadius = CORNER_RADIUS
   element.layer.maskedCorners = [.layerMaxXMaxYCorner]
} else {
   // Fallback on earlier versions
}

And you can using this in table view cell.

For each element inside document body modify their text using .text(fn) function.

$("body *").text(function() {

});

If you want to check for authenticated users in your template then:

    <p>Authenticated user</p>
{% else %}
    <!-- Do something which you want to do with unauthenticated user -->
{% endif %}

<div ng-bind-html="myText"></div> No need to put into html {{}} interpolation tags like you did {{myText}}.

and don't forget to use ngSanitize in module like e.g. var app = angular.module("myApp", ['ngSanitize']);

step 1 : create layout with name activity_main.xml

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    tools:context=".MainActivity"
    android:background="#c6cabd"
    >
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="17dp"
        android:textColor="#ff0e13"
        />
    <EditText
        android:id="@+id/et"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv"
        android:hint="Input your country"
        />
    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Get EditText Text"
        android:layout_below="@id/et"
        />
</RelativeLayout>

Step 2 : Create class Main.class

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button) findViewById(R.id.btn);
        final TextView tv = (TextView) findViewById(R.id.tv);
        final EditText et = (EditText) findViewById(R.id.et);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String country = et.getText().toString();
                tv.setText("Your inputted country is : " + country);
            }
        });
 }
}

I think that this is the correct way:

class Game extends Eloquent {
    // many more stuff here

    // relation without any constraints ...works fine 
    public function videos() {
        return $this->hasMany('Video');
    }

    // results in a "problem", se examples below
    public function available_videos() {
        return $this->videos()->where('available','=', 1);
    }
}

And then you'll have to

$game = Game::find(1);
var_dump( $game->available_videos()->get() );

If you intend to change A, B, C.... you see high above the columns, you can not. You can hide A, B, C...: Button Office(top left) Excel Options(bottom) Advanced(left) Right looking: Display options fot this worksheet: Select the worksheet(eg. Sheet3) Uncheck: Show column and row headers Ok

Now - no

Prior to Java 7:

Yes, sequence is as follows:

• jvm loads class
• executes static blocks
• looks for main method and invokes it

So, if there's code in a static block, it will be executed. But there's no point in doing that.

How to test that:

public final class Test {
    static {
        System.out.println("FOO");
    }
}

Then if you try to run the class (either form command line with java Test or with an IDE), the result is:

FOO
java.lang.NoSuchMethodError: main

@Html.DropdownListFor(model=model->Gender,new List<SelectListItem>
{
 new ListItem{Text="Male",Value="Male"},
 new ListItem{Text="Female",Value="Female"},
 new ListItem{Text="--- Select -----",Value="-----Select ----"}
}
)

In my experience, most probably its happened with jquery version(using multiple version) conflicts, for sort out the issue we can use a no-conflict method like below.

jQuery.noConflict();
(function( $ ) {
  $(function() {
    // More code using $ as alias to jQuery
    $('button').click(function(){
        $('#modalID').modal('show');
    });
  });
})(jQuery);

You can use a headless firefox with an extension. It's pretty annoying to get running but it does produce good results.

There is another open-source tool which allows you to save all console.log output in a file on your server - JS LogFlush (plug!).

JS LogFlush is an integrated JavaScript logging solution which include:

• cross-browser UI-less replacement of console.log - on client side.
• log storage system - on server side.

Demo

I'm using visual studio 2015 and the solutions given above didn't work for me, so i did the following:

Delete the packages folder from my solution and also bin and obj folders from every project in the solution and give it a rebuild.

Maybe you will have the next error:

unable to locate nuget.exe

To solve this: Change this line in your NuGet.targets file and setting it to true:

<DownloadNuGetExe Condition=" '$(DownloadNuGetExe)' == '' ">true</DownloadNuGetExe>

to

127.0.0.1       abc.com.au def.com.au hij.com.au

Very generally speaking:

An API key simply identifies you.

If there is a public/private distinction, then the public key is one that you can distribute to others, to allow them to get some subset of information about you from the api. The private key is for your use only, and provides access to all of your data.

function countbackgrounds() {
 var book = SpreadsheetApp.getActiveSpreadsheet();
 var sheet = book.getActiveSheet();
 var range_input = sheet.getRange("B3:B4");
 var range_output = sheet.getRange("B6");
 var cell_colors = range_input.getBackgroundColors();
 var color = "#58FA58";
 var count = 0;

 for(var r = 0; r < cell_colors.length; r++) {
   for(var c = 0; c < cell_colors[0].length; c++) {
     if(cell_colors[r][c] == color) {
       count = count + 1;
     }
   }
 }
    range_output.setValue(count);
 }

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

all answers are wrong. "Opera" and "Chrome" are same in all cases.

(edited part)

here is the right answer

if (window.chrome && window.chrome.webstore) {
    // this is Chrome
}

That depends on what type your list is, for ArrayList use:

list.get(0);

for LinkedList use:

list.getFirst();

if you like the array approach:

list.toArray()[0];

A C compiler itself won't provide you with GUI functionality, but there are plenty of libraries for that sort of thing. The most popular is probably GTK+, but it may be a little too complicated if you are just starting out and want to quickly get a GUI up and running.

For something a little simpler, I would recommend IUP. With it, you can use a simple GUI definition language called LED to layout controls (but you can do it with pure C, if you want to).

From a SQLServerCentral.Com article by Ken Powers:

The Semicolon

The semicolon character is a statement terminator. It is a part of the ANSI SQL-92 standard, but was never used within Transact-SQL. Indeed, it was possible to code T-SQL for years without ever encountering a semicolon.

Usage

There are two situations in which you must use the semicolon. The first situation is where you use a Common Table Expression (CTE), and the CTE is not the first statement in the batch. The second is where you issue a Service Broker statement and the Service Broker statement is not the first statement in the batch.

Since you are using an INNER JOIN you can just put the conditions in the WHERE clause, like this:

SELECT 
    p1.kArtikel, 
    p1.cName, 
    p1.cKurzBeschreibung, 
    p1.dLetzteAktualisierung, 
    p1.dErstellt, 
    p1.cSeo,
    p2.kartikelpict,
    p2.nNr,
    p2.cPfad  
FROM 
    tartikel AS p1 INNER JOIN tartikelpict AS p2 
    ON p1.kArtikel = p2.kArtikel
WHERE
  DATE(dErstellt) > (NOW() - INTERVAL 7 DAY)
  AND p2.nNr = 1
ORDER BY 
  p1.kArtikel DESC
LIMIT
    100;

How about

1. First adding your desired result as arraylist and
2. and convert to double array as you want.

Try like this..

import java.util.ArrayList;
import java.util.List;

    public class ArrayTest {

        /**
         * @param args
         */
        public static void main(String[] args) {
            // TODO Auto-generated method stub

            // Your Prepared data. 
            List<double[]> values = new ArrayList<double[]>(2);

            double[] element1 = new double[] { 100, 100, 100, 100, 100 };
            double[] element2 = new double[] { 50, 35, 25, 45, 65 };

            values.add(element1);
            values.add(element2);

            // Add the result to arraylist.
            List<Double> temp = new ArrayList<Double>();
            for(int j=0;j<values.size(); j++) {
                for (int i = 0; i < values.get(0).length; i++) {
                    temp.add(values.get(0)[i]);
                    temp.add(values.get(1)[i]);
                }
            }

            // Convert arraylist to int[].
            Double[] result = temp.toArray(new Double[temp.size()]);
            double[] finalResult = new double[result.length]; // This hold final result.
            for (int i = 0; i < result.length; i++) {
                finalResult[i] = result[i].doubleValue();
            }

            for (int i = 0; i < finalResult.length; i++) {
                System.out.println(finalResult[i]);
            }
        }
    }

The RegEx of accepted answer returns the values including their sourrounding quotation marks: "Foo Bar" and "Another Value" as matches.

Here are RegEx which return only the values between quotation marks (as the questioner was asking for):

Double quotes only (use value of capture group #1):

"(.*?[^\\])"

Single quotes only (use value of capture group #1):

'(.*?[^\\])'

Both (use value of capture group #2):

(["'])(.*?[^\\])\1

-

All support escaped and nested quotes.

I answer this coming from a component-based architecture, where an organisation may be running many components that may rely on each other. During a propagating failure, logging levels should help to identify both which components are affected and which are a root cause.

• ERROR - This component has had a failure and the cause is believed to be internal (any internal, unhandled exception, failure of encapsulated dependency... e.g. database, REST example would be it has received a 4xx error from a dependency). Get me (maintainer of this component) out of bed.

• WARN - This component has had a failure believed to be caused by a dependent component (REST example would be a 5xx status from a dependency). Get the maintainers of THAT component out of bed.

• INFO - Anything else that we want to get to an operator. If you decide to log happy paths then I recommend limiting to 1 log message per significant operation (e.g. per incoming http request).

For all log messages be sure to log useful context (and prioritise on making messages human readable/useful rather than having reams of "error codes")

• DEBUG (and below) - Shouldn't be used at all (and certainly not in production). In development I would advise using a combination of TDD and Debugging (where necessary) as opposed to polluting code with log statements. In production, the above INFO logging, combined with other metrics should be sufficient.

A nice way to visualise the above logging levels is to imagine a set of monitoring screens for each component. When all running well they are green, if a component logs a WARNING then it will go orange (amber) if anything logs an ERROR then it will go red.

In the event of an incident you should have one (root cause) component go red and all the affected components should go orange/amber.

In monodroid, you can do like this for rounded rectangle, and then keeping this as a parent class, editbox and other layout features can be added.

 class CustomeView : TextView
    {
       public CustomeView (Context context, IAttributeSet ) : base (context, attrs)  
        {  
        }
       public CustomeView(Context context, IAttributeSet attrs, int defStyle) : base(context, attrs, defStyle)  
        {  
        }
       protected override void OnDraw(Android.Graphics.Canvas canvas)
       {
           base.OnDraw(canvas);
           Paint p = new Paint();
           p.Color = Color.White;
           canvas.DrawColor(Color.DarkOrange);

           Rect rect = new Rect(0,0,3,3);

           RectF rectF = new RectF(rect);


           canvas.DrawRoundRect( rectF, 1,1, p);



       }  
    }
}

Android SDK implementation of FragmentTransaction wants an Animator while support library wants an Animation, don't ask me why but after strangeluk's comment I looked into android 4.0.3 code and support library. Android SDK uses loadAnimator() and support library uses loadAnimation()

Just had the same problem myself.

What happens is, that even if you drop the database, innodb will still not release disk space. I had to export, stop mysql, remove the files manually, start mysql, create database and users, and then import. Thank god I only had 200MB worth of rows, but it spared 250GB of innodb file.

Fail by design.

Pretty sure you can't do that, as it violates the purpose of uniques.

However, this person seems to have a decent work around: http://sqlservercodebook.blogspot.com/2008/04/multiple-null-values-in-unique-index-in.html

Write the following code in the .cs file:

ListBox.Items.Clear();

Just in case anybody else runs into a similar issue: I kept the fade, but just added data-dismiss="modal" to the save button. Works for me.

My favorite answer is as what the first sentence in this thread suggested. Use an Adjacency List to maintain the hierarchy and use Nested Sets to query the hierarchy.

The problem up until now has been that the coversion method from an Adjacecy List to Nested Sets has been frightfully slow because most people use the extreme RBAR method known as a "Push Stack" to do the conversion and has been considered to be way to expensive to reach the Nirvana of the simplicity of maintenance by the Adjacency List and the awesome performance of Nested Sets. As a result, most people end up having to settle for one or the other especially if there are more than, say, a lousy 100,000 nodes or so. Using the push stack method can take a whole day to do the conversion on what MLM'ers would consider to be a small million node hierarchy.

I thought I'd give Celko a bit of competition by coming up with a method to convert an Adjacency List to Nested sets at speeds that just seem impossible. Here's the performance of the push stack method on my i5 laptop.

Duration for     1,000 Nodes = 00:00:00:870 
Duration for    10,000 Nodes = 00:01:01:783 (70 times slower instead of just 10)
Duration for   100,000 Nodes = 00:49:59:730 (3,446 times slower instead of just 100) 
Duration for 1,000,000 Nodes = 'Didn't even try this'

And here's the duration for the new method (with the push stack method in parenthesis).

Duration for     1,000 Nodes = 00:00:00:053 (compared to 00:00:00:870)
Duration for    10,000 Nodes = 00:00:00:323 (compared to 00:01:01:783)
Duration for   100,000 Nodes = 00:00:03:867 (compared to 00:49:59:730)
Duration for 1,000,000 Nodes = 00:00:54:283 (compared to something like 2 days!!!)

Yes, that's correct. 1 million nodes converted in less than a minute and 100,000 nodes in under 4 seconds.

You can read about the new method and get a copy of the code at the following URL. http://www.sqlservercentral.com/articles/Hierarchy/94040/

I also developed a "pre-aggregated" hierarchy using similar methods. MLM'ers and people making bills of materials will be particularly interested in this article. http://www.sqlservercentral.com/articles/T-SQL/94570/

If you do stop by to take a look at either article, jump into the "Join the discussion" link and let me know what you think.

A late answer but I hope it will help anyone visiting here later too..

I will provide categories to save and their respective best methods...

1. Shared Preferences Use this when storing simple values on storage e.g Color theme, app language, last scroll position(in reading apps).. these are simple settings that you would want to persist when the app restarts.. You could, however, use this to store large things(Lists, Maps, Images) but that would require serialization and deserialization.. To learn more on this deserialization and serialization go here.
2. Files This helps a lot when you have data that is defined more by you for example log files, image files and maybe you want to export csv files.. I heard that this type of persistence can be washed by storage cleaners once disk runs out of space.. Am not sure as i have never seen it.. This also can store almost anything but with the help of serialization and deserialization..
3. Saving to a database This is enormously helpful in data which is a bit complex. And I think this doesn't get washed up by disc cleaners as it is stored in AppData(for android).. In this, your data is stored in an SQLite database. Its plugin is SQFLite. Kinds of data that you might wanna put in here are like everything that can be represented by a database.

Well, it's unfortunate that you didn't post your own code too, so that it could be corrected.
Anyway, here's my own solution to this:

@echo off
setlocal enabledelayedexpansion

set OUTPUT_FILE=result.txt
>nul copy nul %OUTPUT_FILE%
for /f %%i in (testservers.txt) do (
    set SERVER_ADDRESS=ADDRESS N/A
    for /f "tokens=1,2,3" %%x in ('ping -n 1 %%i ^&^& echo SERVER_IS_UP') do (
        if %%x==Pinging set SERVER_ADDRESS=%%y
        if %%x==Reply set SERVER_ADDRESS=%%z
        if %%x==SERVER_IS_UP (set SERVER_STATE=UP) else (set SERVER_STATE=DOWN)
    )
    echo %%i [!SERVER_ADDRESS::=!] is !SERVER_STATE! >>%OUTPUT_FILE%
)

The outer loop iterates through the hosts and the inner loop parses the ping output. The first two if statements handle the two possible cases of IP address resolution:

1. The host name is the host IP address.
2. The host IP address can be resolved from its name.

If the host IP address cannot be resolved, the address is set to "ADDRESS N/A".

Hope this helps.

You can use insert:

a = [1,2,3]
a.insert(0,'x')
=> ['x',1,2,3]

Where the first argument is the index to insert at and the second is the value.

maybe you need to grant more permissions to your files.

suppose your code are under /var/www/my_project

try chmod -R 777 /var/www/my_project

^[^<>]+$

The caret in the character class ([^) means match anything but, so this means, beginning of string, then one or more of anything except < and >, then the end of the string.

If you use a virtual environment and Windows 10 (maybe it's the same for other systems), you just need to put geckodriver.exe into the following folder in your virtual environment directory:

...\my_virtual_env_directory\Scripts\geckodriver.exe

Use ON DUPLICATE KEY UPDATE ...,
Negative : because the UPDATE uses resources for the second action.

Use INSERT IGNORE ...,
Negative : MySQL will not show any errors if something goes wrong, so you cannot handle the errors. Use it only if you don’t care about the query.

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

Check out http://mywiki.wooledge.org/DotFiles for an excellent resource on the topic aside from man bash.

Summary:

• You only log in once, and that's when ~/.bash_profile or ~/.profile is read and executed. Since everything you run from your login shell inherits the login shell's environment, you should put all your environment variables in there. Like LESS, PATH, MANPATH, LC_*, ... For an example, see: My .profile
• Once you log in, you can run several more shells. Imagine logging in, running X, and in X starting a few terminals with bash shells. That means your login shell started X, which inherited your login shell's environment variables, which started your terminals, which started your non-login bash shells. Your environment variables were passed along in the whole chain, so your non-login shells don't need to load them anymore. Non-login shells only execute ~/.bashrc, not /.profile or ~/.bash_profile, for this exact reason, so in there define everything that only applies to bash. That's functions, aliases, bash-only variables like HISTSIZE (this is not an environment variable, don't export it!), shell options with set and shopt, etc. For an example, see: My .bashrc
• Now, as part of UNIX peculiarity, a login-shell does NOT execute ~/.bashrc but only ~/.profile or ~/.bash_profile, so you should source that one manually from the latter. You'll see me do that in my ~/.profile too: source ~/.bashrc.

I would like to add for the sake of completeness that you can also add just the LIBRARY PATH where it will look for a dependent library (which may not be directly referenced in your code but a library you use may need it).

For comparison, this would correspond to what LIBPATH environment does but its kind of obscure in Qt Creator and not well documented.

The way i came around this is following:

LIBS += -L"$$_PRO_FILE_PWD_/Path_to_Psapi_lib/"

Essentially if you don't provide the actual library name, it adds the path to where it will search dependent libraries. The difference in syntax is small but this is very useful to supply just the PATH where to look for dependent libraries. It sometime is just a pain to supply each path individual library where you know they are all in certain folder and Qt Creator will pick them up.

you can also use a hashmap for this

@GetMapping
public HashMap<String, Object> get() {
    HashMap<String, Object> map = new HashMap<>();
    map.put("key1", "value1");
    map.put("results", somePOJO);
    return map;
}

Here's a cross-browser less mixin for using CSS's calc with any property:

.calc(@prop; @val) {
  @{prop}: calc(~'@{val}');
  @{prop}: -moz-calc(~'@{val}');
  @{prop}: -webkit-calc(~'@{val}');
  @{prop}: -o-calc(~'@{val}');
}

Example usage:

.calc(width; "100% - 200px");

And the CSS that's output:

width: calc(100% - 200px);
width: -moz-calc(100% - 200px);
width: -webkit-calc(100% - 200px);
width: -o-calc(100% - 200px);

A codepen of this example: http://codepen.io/patrickberkeley/pen/zobdp

This will return all the running java processes in linux environment. Then you can kill the process using the process ID.

ps -e|grep java

I prefer this as the best way of reversing a string using a for loop.

def reverse_a_string(str): 

    result=" "
    for i in range(len(str),1,-1):
        result= result+ str[i-1]
    return result

print reverse_a_string(input())

Using Moshi:

When building your Retrofit Service add .asLenient() to your MoshiConverterFactory. You don't need a ScalarsConverter. It should look something like this:

return Retrofit.Builder()
                .client(okHttpClient)
                .baseUrl(ENDPOINT)
                .addConverterFactory(MoshiConverterFactory.create().asLenient())
                .build()
                .create(UserService::class.java)

As to your bonus question, try if (jQuery.inArray(jQuery("input:first").val(), ar) < 0)

You can do it by making the background into a pattern:

<defs>
  <pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
    <image href="wall.jpg" x="0" y="0" width="100" height="100" />
  </pattern>
</defs>

Adjust the width and height according to your image, then reference it from the path like this:

<path d="M5,50
         l0,100 l100,0 l0,-100 l-100,0
         M215,100
         a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
         M265,50
         l50,100 l-100,0 l50,-100
         z"
  fill="url(#img1)" />

Working example

There's no general way to tell if a file is encoded with a specific encoding. Remember that an encoding is nothing more but an "agreement" how the bits in a file should be mapped to characters.

If you don't know which of your files are actually already encoded in UTF-8 and which ones are encoded in windows-1252, you will have to inspect all files and find out yourself. In the worst case that could mean that you have to open every single one of them with either of the two encodings and see whether they "look" correct -- i.e., all characters are displayed correctly. Of course, you may use tool support in order to do that, for instance, if you know for sure that certain characters are contained in the files that have a different mapping in windows-1252 vs. UTF-8, you could grep for them after running the files through 'iconv' as mentioned by Seva Akekseyev.

Another lucky case for you would be, if you know that the files actually contain only characters that are encoded identically in both UTF-8 and windows-1252. In that case, of course, you're done already.

Swift 5
let desiredIndex: Int = 7 let substring = str[String.Index(encodedOffset: desiredIndex)...]
This substring variable will give you the result.
Simply here Int is converted to Index and then you can split the strings. Unless you will get errors.

Syntax refers to the structure of a language, tracing its etymology to how things are put together.
For example you might require the code to be put together by declaring a type then a name and then a semicolon, to be syntactically correct.

Type token;

On the other hand, the semantics is about meaning. A compiler or interpreter could complain about syntax errors. Your co-workers will complain about semantics.

By default, variables created within a script are only available to the current shell; child processes (sub-shells) will not have access to values that have been set or modified. Allowing child processes to see the values, requires use of the export command.

This will get you the row count, but will leave the data reader at the end.

dataReader.Cast<object>().Count();

This should do it:

<style>
body {
    background:url(bg.jpg) fixed no-repeat bottom right;
}
</style>

If you use Django, it has a built in @classproperty decorator.

from django.utils.decorators import classproperty

Simply navigate to directory and run following command:

du -a --max-depth=1 | sort -n

OR add -h for human readable sizes and -r to print bigger directories/files first.

du -a -h --max-depth=1 | sort -hr

Guard statement going to do . it is couple of different

1) it is allow me to reduce nested if statement
2) it is increase my scope which my variable accessible

if Statement

func doTatal(num1 : Int?, num2: Int?) {
  // nested if statement
    if let fistNum = num1 where num1 > 0 {
        if let lastNum = num2 where num2 < 50 {

          let total = fistNum + lastNum
        }
    }
 // don't allow me to access out of the scope 
 //total = fistNum + lastNum 
}

Guard statement

func doTatal(num1 : Int?, num2: Int?) {
   //reduce  nested if statement and check positive way not negative way 
    guard let fistNum = num1 where num1 > 0 else{
      return
    }
    guard  let lastNum = num2 where num2 < 50 else {
     return
    }
    // increase my scope which my variable accessible
    let total = fistNum + lastNum

}

Math.floor() will work, but it's very slow compared to using a bitwise OR operation:

var rounded = 34.923 | 0;
alert( rounded );
//alerts "34"

EDIT Math.floor() is not slower than using the | operator. Thanks to Jason S for checking my work.

Here's the code I used to test:

var a = [];
var time = new Date().getTime();
for( i = 0; i < 100000; i++ ) {
    //a.push( Math.random() * 100000  | 0 );
    a.push( Math.floor( Math.random() * 100000 ) );
}
var elapsed = new Date().getTime() - time;
alert( "elapsed time: " + elapsed );

I've made a gist with THE perfect method to manage fragment replacement and lifecycle.

It only replace the current fragment by a new one, if it's not the same and if it's not in backstack (in this case it will pop it).

It contain several option as if you want the fragment to be saved in backstack.

=> See Gist here

Using this and a single Activity, you may want to add this to your activity:

@Override
public void onBackPressed() {
    int fragments = getSupportFragmentManager().getBackStackEntryCount();
    if (fragments == 1) {
            finish();
            return;
    }

    super.onBackPressed();
}

You can just convert the string like that [str intValue] or [str integerValue]

integerValue Returns the NSInteger value of the receiver’s text.

• (NSInteger)integerValue Return Value The NSInteger value of the receiver’s text, assuming a decimal representation and skipping whitespace at the beginning of the string. Returns 0 if the receiver doesn’t begin with a valid decimal text representation of a number.

for more information refer here

You don't need to use array_push() function, you can assign new value with new key directly to the array like..

$array = array("color1"=>"red", "color2"=>"blue");
$array['color3']='green';
print_r($array);


Output:

   Array(
     [color1] => red
     [color2] => blue
     [color3] => green
   )

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++. Be aware, however, that it is intended purely as a reference for experienced users willing to devote considerable time and effort to its understanding. The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US). For most people, the final draft before standardization is more than adequate (and free). Many will prefer an even newer draft, documenting new features that are likely to be included in C++20.

• Overview of the New C++ (C++11/14) (PDF only) (Scott Meyers) (updated for C++14) These are the presentation materials (slides and some lecture notes) of a three-day training course offered by Scott Meyers, who's a highly respected author on C++. Even though the list of items is short, the quality is high.

• The C++ Core Guidelines (C++11/14/17/…) (edited by Bjarne Stroustrup and Herb Sutter) is an evolving online document consisting of a set of guidelines for using modern C++ well. The guidelines are focused on relatively higher-level issues, such as interfaces, resource management, memory management and concurrency affecting application architecture and library design. The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• The C++ Super-FAQ (Marshall Cline, Bjarne Stroustrup and others) is an effort by the Standard C++ Foundation to unify the C++ FAQs previously maintained individually by Marshall Cline and Bjarne Stroustrup and also incorporating new contributions. The items mostly address issues at an intermediate level and are often written with a humorous tone. Not all items might be fully up to date with the latest edition of the C++ standard yet.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

Thanks @Harry the following code works for me:

.your-div{
   vertical-align: bottom;
   display: table-cell;
}

the correct answer is @chepner's

EXT=java
for i in *.${EXT}; do
    ...
done

however, here's a small trick to check whether a filename has a given extensions:

EXT=java
for i in *; do
    if [ "${i}" != "${i%.${EXT}}" ];then
        echo "I do something with the file $i"
    fi
done

select Main form -> properties -> Windows style -> icon -> browse your ico

this.Icon = ((System.Drawing.Icon)(resources.GetObject("$this.Icon")));

For anybody reading this in 2019, after React 16.8 was released, take a look at the React Hooks. It really simplifies handling states in components. The docs are very well written with an example of exactly what you need.

I had the same error. Only occurred after moving from my normal work PC to a PC at a different location.

I had to add my public IP ho address to Remote MySQL in my CPanel at my host site

First of all, check if your npm and node installed properly
with commands npm version and node -v.

If they are proper:

1. Find the root global Directory of NPM npm root -g (it will give you root of your global npm store)

2. Uninstall old angular cli with npm uninstall -g angular-cli and npm cache clean

3. Reinstall new Version of angular npm install -g @angular/cli@latest

4. make an Alias of Name ng:

alias ng="C:/ProgramData/npm/node_modules/@angular/cli/bin/ng"

alias ng="<ath-to-your-global-node-modules>/<angular cli path till ng>"
(from answered Oct 20 '16 at 15:30 @m.zemlyanoi )

then to check you can type ng -v

I have always used OLEDB for this, something like...

    Dim sSheetName As String
    Dim sConnection As String
    Dim dtTablesList As DataTable
    Dim oleExcelCommand As OleDbCommand
    Dim oleExcelReader As OleDbDataReader
    Dim oleExcelConnection As OleDbConnection

    sConnection = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\Test.xls;Extended Properties=""Excel 12.0;HDR=No;IMEX=1"""

    oleExcelConnection = New OleDbConnection(sConnection)
    oleExcelConnection.Open()

    dtTablesList = oleExcelConnection.GetSchema("Tables")

    If dtTablesList.Rows.Count > 0 Then
        sSheetName = dtTablesList.Rows(0)("TABLE_NAME").ToString
    End If

    dtTablesList.Clear()
    dtTablesList.Dispose()

    If sSheetName <> "" Then

        oleExcelCommand = oleExcelConnection.CreateCommand()
        oleExcelCommand.CommandText = "Select * From [" & sSheetName & "]"
        oleExcelCommand.CommandType = CommandType.Text

        oleExcelReader = oleExcelCommand.ExecuteReader

        nOutputRow = 0

        While oleExcelReader.Read

        End While

        oleExcelReader.Close()

    End If

    oleExcelConnection.Close()

The ACE.OLEDB provider will read both .xls and .xlsx files and I have always found the speed quite good.

It is possible to do with CSS only by selecting active and focus pseudo element of the button.

button:active{
    background:olive;
}

button:focus{
    background:olive;
}

See codepen: http://codepen.io/fennefoss/pen/Bpqdqx

You could also write a simple jQuery click function which changes the background color.

HTML:

<button class="js-click">Click me!</button>

CSS:

button {
  background: none;
}

JavaScript:

  $( ".js-click" ).click(function() {
    $( ".js-click" ).css('background', 'green');
  });

Check out this codepen: http://codepen.io/fennefoss/pen/pRxrVG

In Swift 5, you can utilize dot notation for a bit quicker syntax:

myButton.titleLabel?.font = .systemFont(ofSize: 14, weight: .medium)

Otherwise, you'll use:

myButton.titleLabel?.font = UIFont.systemFont(ofSize: 14, weight: .medium)

In Mgmt Studio, right-click on your original database then Tasks then Generate Scripts... - follow the wizard.

Float has 32 bit (4 bytes) with 8 places accuracy. Double has 64 bit (8 bytes) with 16 places accuracy.

If you need better accuracy, use Double instead of Float.

There are several ways of consoling out the variable within a string.

Method 1 :

console.log("story", name, "story");

Benefit : if name is a JSON object, it will not be printed as "story" [object Object] "story"

Method 2 :

console.log("story " + name + " story");

Method 3: When using ES6 as mentioned above

console.log(`story ${name} story`);

Benefit: No need of extra , or +

Method 4:

console.log('story %s story',name);

Benefit: the string becomes more readable.

You can declare SqlConnection and SqlCommand instances at global level so that you can use it through out the class. Connection string is in Web.Config.

SqlConnection sqlConn = new SqlConnection(WebConfigurationManager.ConnectionStrings["SqlConnector"].ConnectionString);
SqlCommand sqlcomm = new SqlCommand();

Now you can use the below method to pass values to Stored Procedure and get the DataSet.

public DataSet GetDataSet(string paramValue)
{
    sqlcomm.Connection = sqlConn;
    using (sqlConn)
    {
        try
        {
            using (SqlDataAdapter da = new SqlDataAdapter())
            {  
                // This will be your input parameter and its value
                sqlcomm.Parameters.AddWithValue("@ParameterName", paramValue);

                // You can retrieve values of `output` variables
                var returnParam = new SqlParameter
                {
                    ParameterName = "@Error",
                    Direction = ParameterDirection.Output,
                    Size = 1000
                };
                sqlcomm.Parameters.Add(returnParam);
                // Name of stored procedure
                sqlcomm.CommandText = "StoredProcedureName";
                da.SelectCommand = sqlcomm;
                da.SelectCommand.CommandType = CommandType.StoredProcedure;

                DataSet ds = new DataSet();
                da.Fill(ds);                            
            }
        }
        catch (SQLException ex)
        {
            Console.WriteLine("SQL Error: " + ex.Message);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }
    return new DataSet();
}

The following is the sample of connection string in config file

<connectionStrings>
    <add name="SqlConnector"
         connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=YourDatabaseName;User id=YourUserName;Password=YourPassword"
         providerName="System.Data.SqlClient" />
</connectionStrings>

Using parameter --force:

npm i -f

I know it's not C#, but it's surprising curious that in python the "get the first char of the string representation of the number" is the faster!

EDIT: no, I made a mistake, I forgot to construct again the int, sorry. The unrolled version it's the fastest.

$ cat first_digit.py
def loop(n):
    while n >= 10:
        n /= 10
    return n

def unrolled(n):
    while n >= 100000000: # yea... unlimited size int supported :)
        n /= 100000000
    if n >= 10000:
        n /= 10000
    if n >= 100:
        n /= 100
    if n >= 10:
        n /= 10
    return n

def string(n):
    return int(str(n)[0])
$ python -mtimeit -s 'from first_digit import loop as test' \
    'for n in xrange(0, 100000000, 1000): test(n)'
10 loops, best of 3: 275 msec per loop
$ python -mtimeit -s 'from first_digit import unrolled as test' \
    'for n in xrange(0, 100000000, 1000): test(n)'
10 loops, best of 3: 149 msec per loop
$ python -mtimeit -s 'from first_digit import string as test' \
    'for n in xrange(0, 100000000, 1000): test(n)'
10 loops, best of 3: 284 msec per loop
$

Since don't know which version of automake you can use DESTDIR environment variable.
See Makefile to be sure.

For example:

 export DESTDIR="$HOME/Software/LocalInstall" && make -j4 install

Okay, I've compiled the Time and Space complexities of basic operations on graphs.
The image below should be self-explanatory.
Notice how Adjacency Matrix is preferable when we expect the graph to be dense, and how Adjacency List is preferable when we expect the graph to be sparse.
I've made some assumptions. Ask me if a complexity (Time or Space) needs clarification. (For example, For a sparse graph, I've taken En to be a small constant, as I've assumed that addition of a new vertex will add only a few edges, because we expect the graph to remain sparse even after adding that vertex.)

Please tell me if there are any mistakes.

1) Change your .net profile from Client profile to to .Net Framework 4.0 http://msdn.microsoft.com/en-us/library/bb398202.aspx

2) Check your Embed Interop Types flag

http://weblogs.asp.net/cazzu/archive/2011/03/11/check-your-embed-interop-types-flag-when-doing-visual-studio-extensibility-work.aspx

If you're using @ConfigurationProperties with Spring Boot 2 to inject maps with keys that contain colons then you need an additional level of escaping using square brackets inside the quotes because spring only allows alphanumeric and '-' characters, stripping out the rest. Your new key would look like this:

"[8.11.32.120:8000]": GoogleMapsKeyforThisDomain

See this github issue for reference.

You can assign one color to every functionality to make it more useful.

#define Color_Red "\33[0:31m\\]" // Color Start
#define Color_end "\33[0m\\]" // To flush out prev settings
#define LOG_RED(X) printf("%s %s %s",Color_Red,X,Color_end)

foo()
{
LOG_RED("This is in Red Color");

Like wise you can select different color codes and make this more generic.

This post asked a similar question and used LINQ to solve it, maybe it will help you out too.

string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
int[] ia = s1.Split(';').Select(n => Convert.ToInt32(n)).ToArray();

You need the data to be in "tall" format instead of "wide" for ggplot2. "wide" means having an observation per row with each variable as a different column (like you have now). You need to convert it to a "tall" format where you have a column that tells you the name of the variable and another column that tells you the value of the variable. The process of passing from wide to tall is usually called "melting". You can use tidyr::gather to melt your data frame:

library(ggplot2)
library(tidyr)

test_data <-
  data.frame(
    var0 = 100 + c(0, cumsum(runif(49, -20, 20))),
    var1 = 150 + c(0, cumsum(runif(49, -10, 10))),
    date = seq(as.Date("2002-01-01"), by="1 month", length.out=100)
  )
test_data %>%
    gather(key,value, var0, var1) %>%
    ggplot(aes(x=date, y=value, colour=key)) +
    geom_line()

Just to be clear the data that ggplot is consuming after piping it via gather looks like this:

date        key     value
2002-01-01  var0    100.00000
2002-02-01  var0    115.16388 
...
2007-11-01  var1    114.86302
2007-12-01  var1    119.30996

Here's another dodge that I came up with for my base repository class where I needed to order by an arbitrary number of columns:

public function findAll(array $where = [], array $with = [], array $orderBy = [], int $limit = 10)
{
    $result = $this->model->with($with);
    $dataSet = $result->where($where)
        // Conditionally use $orderBy if not empty
        ->when(!empty($orderBy), function ($query) use ($orderBy) {
            // Break $orderBy into pairs
            $pairs = array_chunk($orderBy, 2);
            // Iterate over the pairs
            foreach ($pairs as $pair) {
                // Use the 'splat' to turn the pair into two arguments
                $query->orderBy(...$pair);
            }
        })
        ->paginate($limit)
        ->appends(Input::except('page'));

    return $dataSet;
}

Now, you can make your call like this:

$allUsers = $userRepository->findAll([], [], ['name', 'DESC', 'email', 'ASC'], 100);

If you don't want to use WMI, I can suggest systeminfo.exe. But, there may be a better way to do that.

(systeminfo | Select-String 'Total Physical Memory:').ToString().Split(':')[1].Trim()

For perl,

To run perl script use this procedure

Requirement: You need to setup classpath variable.

Go to plugins->NppExec->Execute

In command section, type this

cmd /c cd "$(CURRENT_DIRECTORY)"&&"$(FULL_CURRENT_PATH)"

Save it and give name to it.(I give Perl).

Press OK. If editor wants to restart, do it first.

Now press F6 and you will find your Perl script output on below side.

Note: Not required seperate config for seperate files.

For java,

Requirement: You need to setup JAVA_HOME and classpath variable.

Go to plugins->NppExec->Execute

In command section, type this

cmd /c cd "$(CURRENT_DIRECTORY)"&&"%JAVA_HOME%\bin\javac""$(FULL_CURRENT_PATH)"

your *.class will generate on location of current folder; despite of programming error.

For Python,

Use this Plugin Python Plugin

Go to plugins->NppExec-> Run file in Python intercative

By using this you can run scripts within Notepad++.

For PHP,

No need for different configuration just download this plugin.

PHP Plugin and done.

For C language,

Requirement: You need to setup classpath variable.
I am using MinGW compiler.

Go to plugins->NppExec->Execute

paste this into there

   NPP_SAVE

   CD $(CURRENT_DIRECTORY)

   C:\MinGW32\bin\gcc.exe -g "$(FILE_NAME)" 

   a

(Remember to give above four lines separate lines.)

Now, give name, save and ok.

Restart Npp.

Go to plugins->NppExec->Advanced options.

Menu Item->Item Name (I have C compiler)

Associated Script-> from combo box select the above name of script.

Click on Add/modify and Ok.

Now assign shortcut key as given in first answer.

Press F6 and select script or just press shortcut(I assigned Ctrl+2).

For C++,

Only change g++ instead of gcc and *.cpp instead on *.c

That's it!!

First of all make sure you have configured your database in Startup.cs In my case, i was getting this error since i didn't specify the below in Startup.cs

    services.AddDbContext<ApplicationDbContext>(options =>
        options.UseSqlServer(
            Configuration.GetConnectionString("DefaultConnection"), x => x.MigrationsAssembly("<Your Project Assembly name where DBContext class resides>")));

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react-dom.min.js"></script>_x000D_
<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

Try any one of the below. These should work:

int a = Character.getNumericValue('3');
int a = Integer.parseInt(String.valueOf('3');

In 2017 do so

_.chain(data)
  .groupBy("color")
  .toPairs()
  .map(item => _.zipObject(["color", "users"], item))
  .value();

Use alter session set current_schema = <username>, in your case as an execute immediate.

See Oracle's documentation for further information.

In your case, that would probably boil down to (untested)

DECLARE

   CURSOR client_cur IS
     SELECT  distinct username 
       from all_users 
      where length(username) = 3;

   -- client cursor 
   CURSOR emails_cur IS
   SELECT id, name 
     FROM org;

BEGIN

   FOR client IN client_cur LOOP

   -- ****
      execute immediate 
     'alter session set current_schema = ' || client.username;
   -- ****

      FOR email_rec in client_cur LOOP

         dbms_output.put_line(
             'Org id is ' || email_rec.id || 
             ' org nam '  || email_rec.name);

      END LOOP;

  END LOOP;
END;
/

Try to use memory-mapped files.

To me a simple

sudo apt-get update

solved the issue. It was a clock issue and with this command it resets to the current date/time and everything worked

I know this is an old post, but I found my way here in 2018, so maybe someone else will too. In my opinion, the OP had a better approach (using dgv_DataBindingComplete event) than any of the answers provided. At the time of writing, all of the answers are written using paint events or cellformatting events which seems inefficient.

The OP was 99% of the way there, all they had to do was loop through their rows, test the cell value of each row, and set the BackColor, ForeColor, or whatever other property you want to set.

Please excuse the vb.NET syntax, but I think its close enough to C# that it should be clear.

I'm not Reputable enough to upvote or comment yet, but LukeH's answer was spot on for me.

As AES encryption is the standard to use now, it produces a base64 string (at least all the encrypt/decrypt implementations I've seen). This string has a length in multiples of 4 (string.length % 4 = 0)

The strings I was getting contained + and = on the beginning or end, and when you just concatenate that into a URL's querystring, it will look right (for instance, in an email you generate), but when the the link is followed and the .NET page recieves it and puts it into this.Page.Request.QueryString, those special characters will be gone and your string length will not be in a multiple of 4.

As the are special characters at the FRONT of the string (ex: +), as well as = at the end, you can't just add some = to make up the difference as you are altering the cypher text in a way that doesn't match what was actually in the original querystring.

So, wrapping the cypher text with HttpUtility.URLEncode (not HtmlEncode) transforms the non-alphanumeric characters in a way that ensures .NET parses them back into their original state when it is intepreted into the querystring collection.

The good thing is, we only need to do the URLEncode when generating the querystring for the URL. On the incoming side, it's automatically translated back into the original string value.

Here's some example code

string cryptostring = MyAESEncrypt(MySecretString);
string URL = WebFunctions.ToAbsoluteUrl("~/ResetPassword.aspx?RPC=" + HttpUtility.UrlEncode(cryptostring));

My solution

• Assuming that form id = "my_form_id"
• It detects the form method and form action from HTML

jQuery code

$('#my_form_id').on('submit', function(e) {
    e.preventDefault();
    var formData = new FormData($(this)[0]);
    var msg_error = 'An error has occured. Please try again later.';
    var msg_timeout = 'The server is not responding';
    var message = '';
    var form = $('#my_form_id');
    $.ajax({
        data: formData,
        async: false,
        cache: false,
        processData: false,
        contentType: false,
        url: form.attr('action'),
        type: form.attr('method'),
        error: function(xhr, status, error) {
            if (status==="timeout") {
                alert(msg_timeout);
            } else {
                alert(msg_error);
            }
        },
        success: function(response) {
            alert(response);
        },
        timeout: 7000
    });
});

There is a difference between the navigation bar and the status bar. The confusing part is that it looks like one solid feature at the top of the screen, but the areas can actually be separated into two distinct views; a status bar and a navigation bar. The status bar spans from y=0 to y=20 points and the navigation bar spans from y=20 to y=64 points. So the navigation bar (which is where the page title and navigation buttons go) has a height of 44 points, but the status bar and navigation bar together have a total height of 64 points.

Here is a great resource that addresses this question along with a number of other sizing idiosyncrasies in iOS7: http://ivomynttinen.com/blog/the-ios-7-design-cheat-sheet/

Maybe not safe and pretty but if you must:

class string
{
    private $Text;
    public function __construct($value)
    {
        $this->Text = $value;
    }

    public function __toString()
    {
        return $this->Text;
    }
}

function Test123(string $s)
{
    echo $s;
}

Test123(new string("Testing"));

scan 0 MATCH * COUNT 1000 // it gets all the keys if return is "0" as first element then count is less than 1000 if more then it will return the pointer as first element and >scan pointer_val MATCH * COUNT 1000 to get the next set of keys it continues till the first value is "0".

An important point to remember is if you're behind a corporate firewall and you get you're corporate proxy settings from a .pac file, then be sure to use the value for global proxy.

I actually had the same problem with a completely new repository. I had even tried creating one with git checkout -b master, but it would not create the branch. I then realized if I made some changes and committed them, git created my master branch.

Take a look at the ATI Stream Computing SDK. It is based on BrookGPU developed at Stanford.

In the future all GPU work will be standardized using OpenCL. It's an Apple-sponsored initiative that will be graphics card vendor neutral.

I think easiest way to see final query text when you use pdo is to make special error and look error message. I don't know how to do that, but when i make sql error in yii framework that use pdo i could see query text

for (int i = 0; i < 5; i++){
    int asciiVal = rand()%26 + 97;
    char asciiChar = asciiVal;
    cout << asciiChar << " and ";
}

Define your XML layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.neoecosystem.samplex.SwitchActivity">

    <Switch
        android:id="@+id/myswitch"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content" />

</RelativeLayout> 

Then create an Activity

public class SwitchActivity extends ActionBarActivity implements CompoundButton.OnCheckedChangeListener {

    Switch mySwitch = null;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_switch);


        mySwitch = (Switch) findViewById(R.id.myswitch);
        mySwitch.setOnCheckedChangeListener(this);
    }

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        if (isChecked) {
            // do something when check is selected
        } else {
            //do something when unchecked
        }
    }

    ****
}

Since assertThat which was the old answer is now deprecated, I am posting the correct solution:

assertTrue(objectUnderTest instanceof TargetObject);

Not all parameters are supported by all cameras - actually, they are one of the most troublesome part of the OpenCV library. Each camera type - from android cameras to USB cameras to professional ones offer a different interface to modify its parameters. There are many branches in OpenCV code to support as many of them, but of course not all possibilities are covered.

What you can do is to investigate your camera driver, write a patch for OpenCV and send it to code.opencv.org. This way others will enjoy your work, the same way you enjoy others'.

There is also a possibility that your camera does not support your request - most USB cams are cheap and simple. Maybe that parameter is just not available for modifications.

If you are sure the camera supports a given param (you say the camera manufacturer provides some code) and do not want to mess with OpenCV, you can wrap that sample code in C++ with boost::python, to make it available in Python. Then, enjoy using it.

I stumbled across this article in my search for this same answer. What I ended up doing is just popping out obj.pop() all the stored values/objects in my object so I could reuse the object. Not sure if this is bad practice or not. This technique came in handy for me testing my code in Chrome Dev tools or FireFox Web Console.

Html::activeDropDownList($model, 'id', ArrayHelper::map(AttendanceLabel::find()->all(), 'id', 'label_name'), ['prompt'=>'Attendance Status'] );

I have edited for you:

function getHost($Address) { 
    $parseUrl = parse_url(trim($Address));
    $host = trim($parseUrl['host'] ? $parseUrl['host'] : array_shift(explode('/', $parseUrl['path'], 2))); 

    $parts = explode( '.', $host );
    $num_parts = count($parts);

    if ($parts[0] == "www") {
        for ($i=1; $i < $num_parts; $i++) { 
            $h .= $parts[$i] . '.';
        }
    }else {
        for ($i=0; $i < $num_parts; $i++) { 
            $h .= $parts[$i] . '.';
        }
    }
    return substr($h,0,-1);
}

All type url (www.domain.ltd, sub1.subn.domain.ltd will result to : domain.ltd.

Binary Search

You can use Collections.binarySearch to search an element in your list (assuming the list is sorted):

Collections.binarySearch(list, new YourObject("a1", "b",
                "c"), new Comparator<YourObject>() {

            @Override
            public int compare(YourObject o1, YourObject o2) {
                return o1.getName().compareTo(o2.getName());
            }
        });

which will return a negative number if the object is not present in the collection or else it will return the index of the object. With this you can search for objects with different searching strategies.

In Spark 2.0 (I didn't tested with earlier versions). Simply:

print myRDD.take(n)

Where n is the number of lines and myRDD is wc in your case.

Jano's answer is the easiest way to find it.. another way would be if you click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column...

The most common reason could be the database connection string. You have to change the connection string attachDBFile=|DataDirectory|file_name.mdf. there might be problem in host name which would be (local),localhost or .\sqlexpress.

This may also can help

input="inputtext"
output="outputtext"
sed "s/$input/${output}/" inputfile > outputfile

/usr/bin/xcodebuild -version

will give you the xcode version, run it via Terminal command

Here are two very short texts to compare:

1. Julie loves me more than Linda loves me

2. Jane likes me more than Julie loves me

We want to know how similar these texts are, purely in terms of word counts (and ignoring word order). We begin by making a list of the words from both texts:

me Julie loves Linda than more likes Jane

Now we count the number of times each of these words appears in each text:

   me   2   2
 Jane   0   1
Julie   1   1
Linda   1   0
likes   0   1
loves   2   1
 more   1   1
 than   1   1

We are not interested in the words themselves though. We are interested only in those two vertical vectors of counts. For instance, there are two instances of 'me' in each text. We are going to decide how close these two texts are to each other by calculating one function of those two vectors, namely the cosine of the angle between them.

The two vectors are, again:

a: [2, 0, 1, 1, 0, 2, 1, 1]

b: [2, 1, 1, 0, 1, 1, 1, 1]

The cosine of the angle between them is about 0.822.

These vectors are 8-dimensional. A virtue of using cosine similarity is clearly that it converts a question that is beyond human ability to visualise to one that can be. In this case you can think of this as the angle of about 35 degrees which is some 'distance' from zero or perfect agreement.

This exception can raise when you handle Deep linking or URL for a browser, if there is no default installed. In case of Deep linking there may be no application installed that can process a link in format myapp://mylink.

You can use the tangerine solution for API up to 29:

private fun openUrl(url: String) {
    val intent = Intent(Intent.ACTION_VIEW, Uri.parse(url))
    val activityInfo = intent.resolveActivityInfo(packageManager, intent.flags)
    if (activityInfo?.exported == true) {
        startActivity(intent)
    } else {
        Toast.makeText(
            this,
            "No application that can handle this link found",
            Toast.LENGTH_SHORT
        ).show()
    }
}

For API >= 30 see intent.resolveActivity returns null in API 30.

I would prefer this code:

function checkVariable() {

   if (variableLoaded == true) {
       // Here is your next action
   }
 }

 setTimeout(checkVariable, 1000);

You can use double join, if table A B are connected only by table AB.

public static Specification<A> findB(String input) {
    return (Specification<A>) (root, cq, cb) -> {
        Join<A,AB> AjoinAB = root.joinList(A_.AB_LIST,JoinType.LEFT);
        Join<AB,B> ABjoinB = AjoinAB.join(AB_.B,JoinType.LEFT);
        return cb.equal(ABjoinB.get(B_.NAME),input);
    };
}

That's just an another option
Sorry for that timing but I have came across this question and I also wanted to make SELECT IN but I didn't even thought about double join. I hope it will help someone.

Since the class is added dynamically, you need to use event delegation to register the event handler

$(document).on('click', "a.tabclick", function() {
    var liId = $(this).parent("li").attr("id");
    alert(liId);        
});

Use the options command, e.g. options(max.print=1000000).

See ?options:

 ‘max.print’: integer, defaulting to ‘99999’.  ‘print’ or ‘show’
      methods can make use of this option, to limit the amount of
      information that is printed, to something in the order of
      (and typically slightly less than) ‘max.print’ _entries_.

I believe you are looking for:

gethostbyaddress

Just pass it the localhost IP.

There is also a gethostbyname function, that is also usefull.

Not only double quotes, you will be in need for single quote ('), double quote ("), backslash (\) and NUL (the NULL byte).

Use fputcsv() to write, and fgetcsv() to read, which will take care of all.

You need to treat a table valued udf like a table, eg JOIN it

select Emp_Id 
from Employee E JOIN dbo.Splitfn(@Id,',') CSV ON E.Emp_Id = CSV.items 

The two functions do vastly different things!

The resize() method (and passing argument to constructor is equivalent to that) will insert or delete appropriate number of elements to the vector to make it given size (it has optional second argument to specify their value). It will affect the size(), iteration will go over all those elements, push_back will insert after them and you can directly access them using the operator[].

The reserve() method only allocates memory, but leaves it uninitialized. It only affects capacity(), but size() will be unchanged. There is no value for the objects, because nothing is added to the vector. If you then insert the elements, no reallocation will happen, because it was done in advance, but that's the only effect.

So it depends on what you want. If you want an array of 1000 default items, use resize(). If you want an array to which you expect to insert 1000 items and want to avoid a couple of allocations, use reserve().

EDIT: Blastfurnace's comment made me read the question again and realize, that in your case the correct answer is don't preallocate manually. Just keep inserting the elements at the end as you need. The vector will automatically reallocate as needed and will do it more efficiently than the manual way mentioned. The only case where reserve() makes sense is when you have reasonably precise estimate of the total size you'll need easily available in advance.

EDIT2: Ad question edit: If you have initial estimate, then reserve() that estimate. If it turns out to be not enough, just let the vector do it's thing.

You need to open the connection first:

 SQLConnection.Open();

moment().toISOString(); // or format() - see below

http://momentjs.com/docs/#/displaying/as-iso-string/

Update Based on the answer: by @sennet and the comment by @dvlsg (see Fiddle) it should be noted that there is a difference between format and toISOString. Both are correct but the underlying process differs. toISOString converts to a Date object, sets to UTC then uses the native Date prototype function to output ISO8601 in UTC with milliseconds (YYYY-MM-DD[T]HH:mm:ss.SSS[Z]). On the other hand, format uses the default format (YYYY-MM-DDTHH:mm:ssZ) without milliseconds and maintains the timezone offset.

I've opened an issue as I think it can lead to unexpected results.

df.info() function will give you result something like as below. If you are using read_csv method of Pandas without sep parameter or sep with ",".

raw_data = pd.read_csv("a1:\aa2/aaa3/data.csv")
raw_data.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 5144 entries, 0 to 5143
Columns: 145 entries, R_fighter to R_age

Answers by ‘smartnut007’, ‘Bill Karwin’, and ‘sqlvogel’ are excellent. Yet let me put an interesting perspective to it.

Well, we have prime and non-prime keys.

When we focus on how non-primes depend on primes, we see two cases:

Non-primes can be dependent or not.

• When dependent: we see they must depend on a full candidate key. This is 2NF.

• When not dependent: there can be no-dependency or transitive dependency

  • Not even transitive dependency: Not sure what normalization theory addresses this.
  • When transitively dependent: It is deemed undesirable. This is 3NF.

What about dependencies among primes?

Now you see, we’re not addressing the dependency relationship among primes by either 2nd or 3rd NF. Further such dependency, if any, is not desirable and thus we’ve a single rule to address that. This is BCNF.

Referring to the example from Bill Karwin's post here, you’ll notice that both ‘Topping’, and ‘Topping Type’ are prime keys and have a dependency. Had they been non-primes with dependency, then 3NF would have kicked in.

Note:

The definition of BCNF is very generic and without differentiating attributes between prime and non-prime. Yet, the above way of thinking helps to understand how some anomaly is percolated even after 2nd and 3rd NF.

Advanced Topic: Mapping generic BCNF to 2NF & 3NF

Now that we know BCNF provides a generic definition without reference to any prime/non-prime attribues, let's see how BCNF and 2/3 NF's are related.

First, BCNF requires (other than the trivial case) that for each functional dependency X -> Y (FD), X should be super-key. If you just consider any FD, then we've three cases - (1) Both X and Y non-prime, (2) Both prime and (3) X prime and Y non-prime, discarding the (nonsensical) case X non-prime and Y prime.

For case (1), 3NF takes care of.

For case (3), 2NF takes care of.

For case (2), we find the use of BCNF

Fast forwarding to 2020, I found this blog post to be the solution: Jest mock default and named export

Using only ES6 module syntax:

// esModule.js
export default 'defaultExport';
export const namedExport = () => {};

// esModule.test.js
jest.mock('./esModule', () => ({
  __esModule: true, // this property makes it work
  default: 'mockedDefaultExport',
  namedExport: jest.fn(),
}));

import defaultExport, { namedExport } from './esModule';
defaultExport; // 'mockedDefaultExport'
namedExport; // mock function

Also one thing you need to know (which took me a while to figure out) is that you can't call jest.mock() inside the test; you must call it at the top level of the module. However, you can call mockImplementation() inside individual tests if you want to set up different mocks for different tests.

The Trace.WriteLine method is a conditionally compiled method. That means that it will only be executed if the TRACE constant is defined when the code is compiled. By default in Visual Studio, TRACE is only defined in DEBUG mode.

Right Click on the Project and Select Properties. Go to the Compile tab. Select Release mode and add TRACE to the defined preprocessor constants. That should fix the issue for you.

execBack(param) {

attr_accessor is just a method. (The link should provide more insight with how it works - look at the pairs of methods generated, and a tutorial should show you how to use it.)

The trick is that class is not a definition in Ruby (it is "just a definition" in languages like C++ and Java), but it is an expression that evaluates. It is during this evaluation when the attr_accessor method is invoked which in turn modifies the current class - remember the implicit receiver: self.attr_accessor, where self is the "open" class object at this point.

The need for attr_accessor and friends, is, well:

1. Ruby, like Smalltalk, does not allow instance variables to be accessed outside of methods¹ for that object. That is, instance variables cannot be accessed in the x.y form as is common in say, Java or even Python. In Ruby y is always taken as a message to send (or "method to call"). Thus the attr_* methods create wrappers which proxy the instance @variable access through dynamically created methods.

2. Boilerplate sucks

Hope this clarifies some of the little details. Happy coding.

¹ This isn't strictly true and there are some "techniques" around this, but there is no syntax support for "public instance variable" access.

Robomongo 0.8.5 definitely works with MongoDB 3.X (mine version of MongoDB is 3.0.7, the newest one).

The following steps should be done to connect to the MongoDB server:

1. Install MongoDB server (on Windows, Linux, etc. Your choice)
2. Run the MongoDB server. Don't set net.bind_ip = 127.0.0.1 if you want the client to connect to the server by server's own IP address!
3. Connect to the server from Robomongo with the server IP address + set authentication if needed.
