Programs & Examples On #Pango

Although the answer that Gunter posted was correct, it is not different than what I already had posted. The problem was not the ENV directive, but the subsequent instruction RUN export $PATH

There's no need to export the environment variables, once you have declared them via ENV in your Dockerfile.

As soon as the RUN export ... lines were removed, my image was built successfully

For me, I have to run

sudo dpkg --add-architecture i386

before running Mike Tang's answer. Otherwise, I can't install ia32-libs.

In MAC OS, just rebooted the computer and it worked after the reboot.

I solved this by killing the mysql process:

ps -ef | grep mysql
kill [the id]

And then I started the server again with:

sudo /etc/init.d/mysql restart

But start works as well:

sudo /etc/init.d/mysql start

Then I logged in as admin, and I was done.

Inspired by PointZeroTwo's answer, here's a sample using NUnit and FakeItEasy.

SystemUnderTest in this example is the class that you want to test - no sample content given for it but I assume you have that already!

[TestFixture]
public class HttpClientTests
{
    private ISystemUnderTest _systemUnderTest;
    private HttpMessageHandler _mockMessageHandler;

    [SetUp]
    public void Setup()
    {
        _mockMessageHandler = A.Fake<HttpMessageHandler>();
        var httpClient = new HttpClient(_mockMessageHandler);

        _systemUnderTest = new SystemUnderTest(httpClient);
    }

    [Test]
    public void HttpError()
    {
        // Arrange
        A.CallTo(_mockMessageHandler)
            .Where(x => x.Method.Name == "SendAsync")
            .WithReturnType<Task<HttpResponseMessage>>()
            .Returns(Task.FromResult(new HttpResponseMessage
            {
                StatusCode = HttpStatusCode.InternalServerError,
                Content = new StringContent("abcd")
            }));

        // Act
        var result = _systemUnderTest.DoSomething();

        // Assert
        // Assert.AreEqual(...);
    }
}

This function will return you the date and time in the following format: YYYY:MM:DD:HH:MM:SS. It also works in Node.js.

function getDateTime() {

    var date = new Date();

    var hour = date.getHours();
    hour = (hour < 10 ? "0" : "") + hour;

    var min  = date.getMinutes();
    min = (min < 10 ? "0" : "") + min;

    var sec  = date.getSeconds();
    sec = (sec < 10 ? "0" : "") + sec;

    var year = date.getFullYear();

    var month = date.getMonth() + 1;
    month = (month < 10 ? "0" : "") + month;

    var day  = date.getDate();
    day = (day < 10 ? "0" : "") + day;

    return year + ":" + month + ":" + day + ":" + hour + ":" + min + ":" + sec;

}

With position fixed, you need to provide values to set where the div will be placed, since it's a fixed position.

Something like....

.test
{
   position:fixed;
   left:100px;
   top:150px;
}

Fixed - Generates an absolutely positioned element, positioned relative to the browser window. The element's position is specified with the "left", "top", "right", and "bottom" properties

More on position here.

To access Oracle from python you need (additionally) the cx_Oracle module. The module must be located either in the system python path or you have to set the PYTHONPATH appropriate.

You could also use wp_list_categories();

wp_list_categories( array('taxonomy' => 'product_cat', 'title_li'  => '') );

In ConcurrentHashMap, the lock is applied to a segment instead of an entire Map. Each segment manages its own internal hash table. The lock is applied only for update operations. Collections.synchronizedMap(Map) synchronizes the entire map.

I have found that the following works well in 2.7.x

import os
two_up = os.path.normpath(os.path.join(__file__,'../'))

Alternative to @HostListener and scroll output on the element I would suggest using fromEvent from RxJS since you can chain it with filter() and distinctUntilChanges() and can easily skip flood of potentially redundant events (and change detections).

Here is a simple example:

// {static: true} can be omitted if you don't need this element/listener in ngOnInit
@ViewChild('elementId', {static: true}) el: ElementRef;

// ...

fromEvent(this.el.nativeElement, 'scroll')
  .pipe(
    // Is elementId scrolled for more than 50 from top?
    map((e: Event) => (e.srcElement as Element).scrollTop > 50),
    // Dispatch change only if result from map above is different from previous result
    distinctUntilChanged());

This will surely work:

UPDATE table1
SET table1.price=(SELECT table2.price
  FROM table2
  WHERE table2.id=table1.id AND table2.item=table1.item);

One thing that is really important for this question (and the answers) is the following: What the hell is functional programming, and what are the most important properties of it. I'll try to give my view of it:

Functional programming is a lot like writing math on a whiteboard. When you write equations on a whiteboard, you do not think about an execution order. There is (typically) no mutation. You don't come back the day after and look at it, and when you make the calculations again, you get a different result (or you may, if you've had some fresh coffee :)). Basically, what is on the board is there, and the answer was already there when you started writing things down, you just haven't realized what it is yet.

Functional programming is a lot like that; you don't change things, you just evaluate the equation (or in this case, "program") and figure out what the answer is. The program is still there, unmodified. The same with the data.

I would rank the following as the most important features of functional programming: a) referential transparency - if you evaluate the same statement at some other time and place, but with the same variable values, it will still mean the same. b) no side effect - no matter how long you stare at the whiteboard, the equation another guy is looking at at another whiteboard won't accidentally change. c) functions are values too. which can be passed around and applied with, or to, other variables. d) function composition, you can do h=g·f and thus define a new function h(..) which is equivalent to calling g(f(..)).

This list is in my prioritized order, so referential transparency is the most important, followed by no side effects.

Now, if you go through python and check how well the language and libraries supports, and guarantees, these aspects - then you are well on the way to answer your own question.

java -classpath Predit.jar your.package.name.MainClass

I don't know if it helps, but using jQuery, to hide an email address, I did :

    $(function() {
        // planque l'adresse mail
        var mailSplitted 
            = ['mai', 'to:mye', 'mail@', 'addre', 'ss.fr'];

        var link = mailSplitted.join('');
        link = '<a href="' + link + '"</a>';
        $('mytag').wrap(link);
    });

I hope it helps.

For disabling swiping

mViewPager.beginFakeDrag();

For enable swiping

if (mViewPager.isFakeDragging()) mViewPager.endFakeDrag();

Set the href attribute with

$(selector).attr('href', 'url_goes_here');

and read it using

$(selector).attr('href');

Where "selector" is any valid jQuery selector for your <a> element (".myClass" or "#myId" to name the most simple ones).

Hope this helps !

Another way to do it if you "own" the module is to use module_function.

module UsefulThings
  def a
    puts "aaay"
  end
  module_function :a

  def b
    puts "beee"
  end
end

def test
  UsefulThings.a
  UsefulThings.b # Fails!  Not a module method
end

test

Apparently some POST requests looks like a "GET" to the server (like Heroku...)

So I use this strategy and it works for me:

@RequestMapping(value = "/salvar", method = { RequestMethod.GET, RequestMethod.POST })

Based on Fedor Kazakov and others answers, I created a default config.

The below worked really good for me. I patched together all the above answers plus read about displaying object properties in the following link and came up with the below short read about printing objects

add the following text to a file named print_object.ps1:

$date = New-Object System.DateTime
Write-Output $date | Get-Member
Write-Output $date | Select-Object -Property *

open powershell command prompt, go to the directory where that file exists and type the following:

powershell -ExecutionPolicy ByPass -File is_port_in_use.ps1 -Elevated

Just substitute 'System.DateTime' with whatever object you wanted to print. If the object is null, nothing will print out.

var arr = new Array();

var blkstr = $.each([1, 2, 3], function(idx2,val2) {                    
    arr.push(idx2 + ":" + val2);
    return arr;
}).join(', ');

console.log(blkstr);

OR

var arr = new Array();

$.each([1, 2, 3], function(idx2,val2) {                    
    arr.push(idx2 + ":" + val2);

});

console.log(arr.join(', '));

Here is the code:

public static void main(String argso[]) {
int big_array[] = new int[100000];

// Do some computations with big_array and get a result. 
int result = compute(big_array);

// We no longer need big_array. It will get garbage collected when there
// are no more references to it. Since big_array is a local variable,
// it refers to the array until this method returns. But this method
// doesn't return. So we've got to explicitly get rid of the reference
// ourselves, so the garbage collector knows it can reclaim the array. 
big_array = null;

// Loop forever, handling the user's input
for(;;) handle_input(result);
}

If you are on JSP, this problem can come from your servlet mapping. if your mapping takes url by defaut like this:

@WebServlet("/")

then the container interpret your css url, and goes to the servlet instead of going to the css file.

i had the same issue, i changed my mapping and now everyting works

I'm not sure what you're doing, but this will go from JSON to CSV using JavaScript. This is using the open source JSON library, so just download JSON.js into the same folder you saved the code below into, and it will parse the static JSON value in json3 into CSV and prompt you to download/open in Excel.

    function DownloadJSON2CSV(objArray)
    {
        var array = typeof objArray != 'object' ? JSON.parse(objArray) : objArray;

        var str = '';

        for (var i = 0; i < array.length; i++) {
            var line = '';

            for (var index in array[i]) {
                line += array[i][index] + ',';
            }

            // Here is an example where you would wrap the values in double quotes
            // for (var index in array[i]) {
            //    line += '"' + array[i][index] + '",';

Scott Gu has an excellent explanation here

There are a lot of good answers here already. But for me it was hard to find some example, where the shape or array can break all the program.

So here is the one:

import numpy as np
a = np.array([1,2,3,4])
b = np.array([10,20,30,40])


from sklearn.linear_model import LinearRegression
regr = LinearRegression()
regr.fit(a,b)

This will fail with error:

ValueError: Expected 2D array, got 1D array instead

but if we add reshape to a:

a = np.array([1,2,3,4]).reshape(-1,1)

this works correctly!

-- -- create procedure to check if a table exists

DELIMITER $$

DROP PROCEDURE IF EXISTS `checkIfTableExists`;

CREATE PROCEDURE checkIfTableExists(
    IN databaseName CHAR(255),
    IN tableName CHAR(255),
    OUT boolExistsOrNot CHAR(40)
)

  BEGIN
      SELECT count(*) INTO boolExistsOrNot FROM information_schema.TABLES
      WHERE (TABLE_SCHEMA = databaseName)
      AND (TABLE_NAME = tableName);
  END $$

DELIMITER ;

-- -- how to use : check if table migrations exists

 CALL checkIfTableExists('muDbName', 'migrations', @output);

for speed you can do this

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

There are MYSQL functions you can use. Like this one that resolves the user:

SELECT USER();

This will return something like root@localhost so you get the host and the user.

To get the current database run this statement:

SELECT DATABASE();

Other useful functions can be found here: http://dev.mysql.com/doc/refman/5.0/en/information-functions.html

I've always thought that DLLs and shared objects are just different terms for the same thing - Windows calls them DLLs, while on UNIX systems they're shared objects, with the general term - dynamically linked library - covering both (even the function to open a .so on UNIX is called dlopen() after 'dynamic library').

They are indeed only linked at application startup, however your notion of verification against the header file is incorrect. The header file defines prototypes which are required in order to compile the code which uses the library, but at link time the linker looks inside the library itself to make sure the functions it needs are actually there. The linker has to find the function bodies somewhere at link time or it'll raise an error. It ALSO does that at runtime, because as you rightly point out the library itself might have changed since the program was compiled. This is why ABI stability is so important in platform libraries, as the ABI changing is what breaks existing programs compiled against older versions.

Static libraries are just bundles of object files straight out of the compiler, just like the ones that you are building yourself as part of your project's compilation, so they get pulled in and fed to the linker in exactly the same way, and unused bits are dropped in exactly the same way.

You can fix it that way:

s = "{'username':'dfdsfdsf'}"
j = eval(s)

After visiting this question and noting the initial concerns of the chosen solution, I figured I'd contribute this one for those not using Java 7 which uses FileUtils instead of IOUtils from Apache Commons. The advantage here is that the readFileToString and the writeStringToFile handle the issue of closing the files for you automatically. (writeStringToFile doesn't document it but you can read the source). Hopefully this recipe simplifies things for anyone new coming to this problem.

  try {
     String content = FileUtils.readFileToString(new File("InputFile"), "UTF-8");
     content = content.replaceAll("toReplace", "replacementString");
     File tempFile = new File("OutputFile");
     FileUtils.writeStringToFile(tempFile, content, "UTF-8");
  } catch (IOException e) {
     //Simple exception handling, replace with what's necessary for your use case!
     throw new RuntimeException("Generating file failed", e);
  }

URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
            new InputStreamReader(
            yahoo.openStream()));

String inputLine;

while ((inputLine = in.readLine()) != null)
    System.out.println(inputLine);

in.close();

json.dumps() is used to decode JSON data

import json

# initialize different data
str_data = 'normal string'
int_data = 1
float_data = 1.50
list_data = [str_data, int_data, float_data]
nested_list = [int_data, float_data, list_data]
dictionary = {
    'int': int_data,
    'str': str_data,
    'float': float_data,
    'list': list_data,
    'nested list': nested_list
}

# convert them to JSON data and then print it
print('String :', json.dumps(str_data))
print('Integer :', json.dumps(int_data))
print('Float :', json.dumps(float_data))
print('List :', json.dumps(list_data))
print('Nested List :', json.dumps(nested_list, indent=4))
print('Dictionary :', json.dumps(dictionary, indent=4))  # the json data will be indented

output:

Integer : 1
Float : 1.5
List : ["normal string", 1, 1.5]
Nested List : [

You can use an npm module called depcheck (requires at least version 10 of Node).

1. Install the module:

    npm install depcheck -g
   
    or
   
    yarn global add depcheck
   

2. Run it and find the unused dependencies:

    depcheck
   

The good thing about this approach is that you don't have to remember the find or grep command.

To run without installing use npx:

npx depcheck 

Use word-wrap:break-word attribute along with required width. Mainly, put the width in pixels, not in percentages.

width: 200px;
word-wrap: break-word;

The --bare flag creates a repository that doesn’t have a working directory. The bare repository is the central repository and you can't edit(store) codes here for avoiding the merging error.

For example, when you add a file in your local repository (machine 1) and push it to the bare repository, you can't see the file in the bare repository for it is always 'empty'. However, you really push something to the repository and you can see it inexplicitly by cloning another repository in your server(machine 2).

Both the local repository in machine 1 and the 'copy' repository in machine 2 are non-bare. relationship between bare and non-bare repositories

The answer is here: http://php.net/manual/en/function.mysql-list-fields.php I'd use the following code in your case:

$result = mysql_query("SHOW COLUMNS FROM sometable");
if (!$result) {
    echo 'Could not run query: ' . mysql_error();
    exit;
}
$fields = array();
if (mysql_num_rows($result) > 0) {
    while ($row = mysql_fetch_assoc($result)) {
        $fields[] = $row['Field'];
    }

For example your file contains :

 1.  mangesh@001:~$ cat output.txt
    1
    2
    EOF

if u want to append at end of file then ---->remember spaces between 'text' >> 'filename'

  2. mangesh@001:~$ echo somthing to append >> output.txt|cat output.txt 
    1
    2
    EOF
    somthing to append

And to overwrite contents of file :

  3.  mangesh@001:~$ echo 'somthing new to write' > output.tx|cat output.tx
    somthing new to write

Now I've found the problem.

Removing the obj_exception_throw from my breakpoints solved this. Now it's caught by the @try block and also, NSSetUncaughtExceptionHandler will handle this if a @try block is missing.

I needed to run a Spring .jar application as a service, and found a simple way to run this as a specific user:

I changed the owner and group of my jar file to the user I wanted to run as. Then symlinked this jar in init.d and started the service.

So:

#chown myuser:myuser /var/lib/jenkins/workspace/springApp/target/springApp-1.0.jar

#ln -s /var/lib/jenkins/workspace/springApp/target/springApp-1.0.jar /etc/init.d/springApp

#service springApp start

#ps aux | grep java
myuser    9970  5.0  9.9 4071348 386132 ?      Sl   09:38   0:21 /bin/java -Dsun.misc.URLClassPath.disableJarChecking=true -jar /var/lib/jenkins/workspace/springApp/target/springApp-1.0.jar

your 8080 port is already used by another application 1/ you can try to find out which app is using it, using "netstat -aon" and stop the process; 2/ you can go to server.xml and change from port 8080 to another one (ex: 8081)

Here's a simple way

for (i in 1:10) {
  
  skip_to_next <- FALSE
  
  # Note that print(b) fails since b doesn't exist
  
  tryCatch(print(b), error = function(e) { skip_to_next <<- TRUE})
  
  if(skip_to_next) { next }     
}

Note that the loop completes all 10 iterations, despite errors. You can obviously replace print(b) with any code you want. You can also wrap many lines of code in { and } if you have more than one line of code inside the tryCatch

You can refresh with this:

map.panBy(0, 0);

Something like this should do it. Just grab the value from the registry

For .NET 1-4:

Framework is the highest installed version, SP is the service pack for that version.

RegistryKey installed_versions = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\NET Framework Setup\NDP");
string[] version_names = installed_versions.GetSubKeyNames();
//version names start with 'v', eg, 'v3.5' which needs to be trimmed off before conversion
double Framework = Convert.ToDouble(version_names[version_names.Length - 1].Remove(0, 1), CultureInfo.InvariantCulture);
int SP = Convert.ToInt32(installed_versions.OpenSubKey(version_names[version_names.Length - 1]).GetValue("SP", 0));

For .NET 4.5+ (from official documentation):

using System;
using Microsoft.Win32;


...


private static void Get45or451FromRegistry()
{
    using (RegistryKey ndpKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32).OpenSubKey("SOFTWARE\\Microsoft\\NET Framework Setup\\NDP\\v4\\Full\\")) {
        int releaseKey = Convert.ToInt32(ndpKey.GetValue("Release"));
        if (true) {
            Console.WriteLine("Version: " + CheckFor45DotVersion(releaseKey));
        }
    }
}


...


// Checking the version using >= will enable forward compatibility,  
// however you should always compile your code on newer versions of 
// the framework to ensure your app works the same. 
private static string CheckFor45DotVersion(int releaseKey)
{
    if (releaseKey >= 461808) {
        return "4.7.2 or later";
    }
    if (releaseKey >= 461308) {
        return "4.7.1 or later";
    }
    if (releaseKey >= 460798) {
        return "4.7 or later";
    }
    if (releaseKey >= 394802) {
        return "4.6.2 or later";
    }
    if (releaseKey >= 394254) {
        return "4.6.1 or later";
    }
    if (releaseKey >= 393295) {
        return "4.6 or later";
    }
    if (releaseKey >= 393273) {
        return "4.6 RC or later";
    }
    if ((releaseKey >= 379893)) {
        return "4.5.2 or later";
    }
    if ((releaseKey >= 378675)) {
        return "4.5.1 or later";
    }
    if ((releaseKey >= 378389)) {
        return "4.5 or later";
    }
    // This line should never execute. A non-null release key should mean 
    // that 4.5 or later is installed. 
    return "No 4.5 or later version detected";
}

Old way:

SELECT DATE_COLUMN + 1 is adding a day
SELECT DATE_COLUMN + N /24 to add hour(s) - N being number of hours
SELECT DATE_COLUMN + N /1440 to add minute(s) - N being number of minutes
SELECT DATE_COLUMN + N /86400 to add second(s) - N being number of seconds

Using INTERVAL:

SELECT DATE_COLUMN + INTERVAL 'N' HOUR or MINUTE or SECOND - N being a number of hours or minutes or seconds.

You should use a List for something like this, not an array. As a general rule of thumb, when you don't know how many elements you will add to an array before hand, use a List instead. Most would probably tackle this problem by using an ArrayList.

If you really can't use a List, then you'll probably have to use an array of some initial size (maybe 10?) and keep track of your array capacity versus how many elements you're adding, and copy the elements to a new, larger array if you run out of room (this is essentially what ArrayList does internally). Also note that, in the real world, you would never do it this way - you would use one of the standard classes that are made specifically for cases like this, such as ArrayList.

Your parameter for the request options in http.put() should actually be of type RequestOptions. Try something like this:

let headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('authentication', `${student.token}`);

let options = new RequestOptions({ headers: headers });
return this.http
    .put(url, JSON.stringify(student), options)

I got this working : -

$.get('api.php', 'client=mikescafe', function(data) {
...
});

It sends via get the string ?client=mikescafe then collect this variable in api.php, and use it in your mysql statement.

One way you could accomplish this (in a hackish way) is to create a wrapper class for the List. Like this:

class ListWrapper {
     List<String> myList; 
     // getters and setters
}

Then your controller method signature would look like this:

public String controllerMethod(ListWrapper wrapper) {
    ....
}

No need to use the @RequestParam or @ModelAttribute annotation if the collection name you pass in the request matches the collection field name of the wrapper class, in my example your request parameters should look like this:

myList[0]     : 'myValue1'
myList[1]     : 'myValue2'
myList[2]     : 'myValue3'
otherParam    : 'otherValue'
anotherParam  : 'anotherValue'

If I'm understanding you correctly, you can simply use .ToString() to retrieve the name of the enum from the value (Assuming it's already cast as the Enum); If you had the naked int (lets say from a database or something) you can first cast it to the enum. Both methods below will get you the enum name.

AuthenticationMethod myCurrentSetting = AuthenticationMethod.FORMS;
Console.WriteLine(myCurrentSetting); // Prints: FORMS
string name = Enum.GetNames(typeof(AuthenticationMethod))[(int)myCurrentSetting-1];
Console.WriteLine(name); // Prints: FORMS

Keep in mind though, the second technique assumes you are using ints and your index is 1 based (not 0 based). The function GetNames also is quite heavy by comparison, you are generating a whole array each time it's called. As you can see in the first technique, .ToString() is actually called implicitly. Both of these are already mentioned in the answers of course, I'm just trying to clarify the differences between them.

You can either use the prepareStatement method taking an additional int parameter

PreparedStatement ps = con.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS)

For some JDBC drivers (for example, Oracle) you have to explicitly list the column names or indices of the generated keys:

PreparedStatement ps = con.prepareStatement(sql, new String[]{"USER_ID"})

Using the cursor based variations above as a starting point, the script below will just output a set of UPDATE statements to set to DATABASE_DEFAULT, it won't actually do the UPDATES.

It supports schema, the full set of char and text types and retains the existing NULL / NOT NULL.

I plan to use the output to find to statements that fail in a lower environment and then manually adapt the resulting script to drop and recreate the constraints as needed.

Best function I have found. Credit to text-ellipsis.

function textEllipsis(str, maxLength, { side = "end", ellipsis = "..." } = {}) {
  if (str.length > maxLength) {
    switch (side) {
      case "start":
        return ellipsis + str.slice(-(maxLength - ellipsis.length));
      case "end":
      default:
        return str.slice(0, maxLength - ellipsis.length) + ellipsis;
    }
  }
  return str;
}

Examples:

var short = textEllipsis('a very long text', 10);
console.log(short);
// "a very ..."

var short = textEllipsis('a very long text', 10, { side: 'start' });
console.log(short);
// "...ng text"

var short = textEllipsis('a very long text', 10, { textEllipsis: ' END' });
console.log(short);
// "a very END"

Simple Solution

// Regexplanation:
// ^       beginning of line
// \\D+    1+ non-digit characters
// (\\d+)  1+ digit characters in a capture group
// .*      0+ any character
String regexStr = "^\\D+(\\d+).*";

// Compile the regex String into a Pattern
Pattern p = Pattern.compile(regexStr);

// Create a matcher with the input String
Matcher m = p.matcher(inputStr);

// If we find a match
if (m.find()) {
    // Get the String from the first capture group
    String someDigits = m.group(1);
    // ...do something with someDigits
}

Solution in a Util Class

public class MyUtil {
    private static Pattern pattern = Pattern.compile("^\\D+(\\d+).*");
    private static Matcher matcher = pattern.matcher("");

    // Assumptions: inputStr is a non-null String
    public static String extractFirstNumber(String inputStr){
        // Reset the matcher with a new input String
        matcher.reset(inputStr);

        // Check if there's a match
        if(matcher.find()){
            // Return the number (in the first capture group)
            return matcher.group(1);
        }else{
            // Return some default value, if there is no match
            return null;
        }
    }
}

...

// Use the util function and print out the result
String firstNum = MyUtil.extractFirstNumber("Testing4234Things");
System.out.println(firstNum);

How about:

(sleep 5; echo "Hello World") &

Here a version that uses shuffle and streams

List<Direction> letters = Arrays.asList(Direction.values());
Collections.shuffle(letters);
return letters.stream().findFirst().get();

For me this worked

mp.seekTo(0);
mp.start();

I think the answer may be easier to understand like this:

$('#empid').on('change',function() {_x000D_
  alert($(this).val());_x000D_
  console.log($(this).val());_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.0/jquery.min.js"></script>_x000D_
<select id="empid" name="empname" multiple="multiple">_x000D_
  <option value="0">Potato</option>_x000D_
  <option value="1">Carrot</option>_x000D_
  <option value="2">Apple</option>_x000D_
  <option value="3">Raisins</option>_x000D_
  <option value="4">Peanut</option>_x000D_
</select>_x000D_
<br />_x000D_
Hold CTRL / CMD for selecting multiple fields

If you select "Carrot" and "Raisins" in the list, the output will be "1,3".

I have BaseModel class, so I needed something more generic.

//app/BaseModel.php
public function rules()
{
    return $rules = [];
}
public function isValid($id = '')
{

    $validation = Validator::make($this->attributes, $this->rules($id));

    if($validation->passes()) return true;
    $this->errors = $validation->messages();
    return false;
}

In user class let's suppose I need only email and name to be validated:

//app/User.php
//User extends BaseModel
public function rules($id = '')
{
    $rules = [
                'name' => 'required|min:3',
                'email' => 'required|email|unique:users,email',
                'password' => 'required|alpha_num|between:6,12',
                'password_confirmation' => 'same:password|required|alpha_num|between:6,12',
            ];
    if(!empty($id))
    {
        $rules['email'].= ",$id";
        unset($rules['password']);
        unset($rules['password_confirmation']);
    }

    return $rules;
}

I tested this with phpunit and works fine.

//tests/models/UserTest.php 
public function testUpdateExistingUser()
{
    $user = User::find(1);
    $result = $user->id;
    $this->assertEquals(true, $result);
    $user->name = 'test update';
    $user->email = '[email protected]';
    $user->save();

    $this->assertTrue($user->isValid($user->id), 'Expected to pass');

}

You need to do the following

git fetch -p

in order to synchronize your branch list. The git manual says

-p, --prune
After fetching, remove any remote-tracking references that no longer exist on the remote. Tags are not subject to pruning if they are fetched only because of the default tag auto-following or due to a --tags option. However, if tags are fetched due to an explicit refspec (either on the command line or in the remote configuration, for example if the remote was cloned with the --mirror option), then they are also subject to pruning.

I personally like to use git fetch origin -p --progress because it shows a progress indicator.

I know this is an old Question

But in case you want to do it programmatically or the java way

For Image Backgrounds; you can use BackgroundImage class

BackgroundImage myBI= new BackgroundImage(new Image("my url",32,32,false,true),
        BackgroundRepeat.REPEAT, BackgroundRepeat.NO_REPEAT, BackgroundPosition.DEFAULT,
          BackgroundSize.DEFAULT);
//then you set to your node
myContainer.setBackground(new Background(myBI));

For Paint or Fill Backgrounds; you can use BackgroundFill class

BackgroundFill myBF = new BackgroundFill(Color.BLUEVIOLET, new CornerRadii(1),
         new Insets(0.0,0.0,0.0,0.0));// or null for the padding
//then you set to your node or container or layout
myContainer.setBackground(new Background(myBF));

Keeps your java alive && your css dead..

To get the width and height of the viewport:

var viewportWidth = $(window).width();
var viewportHeight = $(window).height();

resize event of the page:

$(window).resize(function() {

});

An enumeration is something of an inverse-array. What I believe you want is this:

const char * Week[] = { "", "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };  // The blank string at the beginning is so that Sunday is 1 instead of 0.
cout << "Today is " << Week[2] << ", enjoy!";  // Or whatever you'de like to do with it.

I could use the GetBody from Request package.

Look this comment in source code from request.go in net/http:

GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."

GetBody func() (io.ReadCloser, error)

This way you can get the body request without make it empty.

Sample:

getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
    // Do something return err
}
http.DefaultClient.Do(request)

This is the cleanest way... BY FAR:

Public Function IsDir(s) As Boolean
    IsDir = CreateObject("Scripting.FileSystemObject").FolderExists(s)
End Function

You can't use variable names to bind columns or other system objects, you need dynamic sql

DECLARE @value varchar(10)  
SET @value = 'intStep'  
DECLARE @sqlText nvarchar(1000); 

SET @sqlText = N'SELECT ' + @value + ' FROM dbo.tblBatchDetail'
Exec (@sqlText)

Not sure if Access supports it, but in most engines (including SQL Server) this is called a correlated subquery and works fine:

SELECT  TypesAndBread.Type, TypesAndBread.TBName,
        (
        SELECT  Count(Sandwiches.[SandwichID]) As SandwichCount
        FROM    Sandwiches
        WHERE   (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
                OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
        ) As SandwichCount
FROM    TypesAndBread

This can be made more efficient by indexing Type and Bread and distributing the subqueries over the UNION:

SELECT  [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
        )
FROM    [Sandwiches Types]
UNION ALL
SELECT  [Breads].[Bread] As TBName, "Bread" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Bread = [Breads].[Bread]
        )
FROM    [Breads]

An example using built in TimeUnit.

long uptime = System.currentTimeMillis();

long days = TimeUnit.MILLISECONDS
    .toDays(uptime);
uptime -= TimeUnit.DAYS.toMillis(days);

long hours = TimeUnit.MILLISECONDS
    .toHours(uptime);
uptime -= TimeUnit.HOURS.toMillis(hours);

long minutes = TimeUnit.MILLISECONDS
    .toMinutes(uptime);
uptime -= TimeUnit.MINUTES.toMillis(minutes);

long seconds = TimeUnit.MILLISECONDS
    .toSeconds(uptime);

Starting with 1.6.4, Arduino IDE can be used to program and upload the NodeMCU board by installing the ESP8266 third-party platform package (refer https://github.com/esp8266/Arduino):

• Start Arduino, go to File > Preferences
• Add the following link to the Additional Boards Manager URLs: http://arduino.esp8266.com/stable/package_esp8266com_index.json and press OK button
• Click Tools > Boards menu > Boards Manager, search for ESP8266 and install ESP8266 platform from ESP8266 community (and don't forget to select your ESP8266 boards from Tools > Boards menu after installation)

To install additional ESP8266WiFi library:

• Click Sketch > Include Library > Manage Libraries, search for ESP8266WiFi and then install with the latest version.

After above steps, you should compile the sketch normally.

On Mac, you will find it here: /Users/$username/.android

If the two databases are on the same server, you should be able to create a SQL statement something like this:

UPDATE Test1.dbo.Employee
SET DeptID = emp2.DeptID
FROM Test2.dbo.Employee as 'emp2'
WHERE
   Test1.dbo.Employee.EmployeeID = emp2.EmployeeID

From your post, I'm not quite clear whether you want to update Test1.dbo.Employee with the values from Test2.dbo.Employee (that's what my query does), or the other way around (since you mention the db on Test1 was the new table......)

I am not very good in using sophisticated regular expressions, so I'd do such task in the following way:

files <- list.files()
dbf.files <- files[-grep(".xml", files, fixed=T)]

First line just lists all files from working dir. Second one drops everything containing ".xml" (grep returns indices of such strings in 'files' vector; subsetting with negative indices removes corresponding entries from vector). "fixed" argument for grep function is just my whim, as I usually want it to peform crude pattern matching without Perl-style fancy regexprs, which may cause surprise for me.

I'm aware that such solution simply reflects drawbacks in my education, but for a novice it may be useful =) at least it's easy.

<input ... checked />
<input ... checked="checked" />

Those are equally valid. And in JavaScript:

input.checked = true;
input.setAttribute("checked");
input.setAttribute("checked","checked");

There are a few things which new does that malloc doesn’t:

1. new constructs the object by calling the constructor of that object
2. new doesn’t require typecasting of allocated memory.
3. It doesn’t require an amount of memory to be allocated, rather it requires a number of objects to be constructed.

So, if you use malloc, then you need to do above things explicitly, which is not always practical. Additionally, new can be overloaded but malloc can’t be.

You can't move the mouse pointer using javascript, and thus for obvious security reasons. The best way to achieve this effect would be to actually place the control under the mouse pointer.

I believe alt is required for strict XHTML compliance.

As others have noted, title is for tooltips (nice to have), alt is for accessibility. Nothing wrong with using both, but alt should always be there.

It seems to me that you might be better off with a list rather than using orca1, orca2, etc, ... then it would be orca[1], orca[2], ...

Usually you're making a list of variables differentiated by nothing but a number because that number would be a convenient way to access them later.

orca <- list()
orca[1] <- "Hi"
orca[2] <- 59

Otherwise, assign is just what you want.

If you would like to mount a particular host directory (/disk1/prometheus-data in the following example) as a volume in the volumes section of the Docker Compose YAML file, you can do it as below, e.g.:

version: '3'

services:
  prometheus:
    image: prom/prometheus
    volumes:
      - prometheus-data:/prometheus

volumes:
  prometheus-data:
    driver: local
    driver_opts:
      o: bind
      type: none
      device: /disk1/prometheus-data

By the way, in prometheus's Dockerfile, You may find the VOLUME instruction as below, which marks it as holding externally mounted volumes from native host, etc. (Note however: this instruction is not a must though to mount a volume into a container.):

Dockerfile

...
VOLUME ["/prometheus"]
...

There is an option “unlimited scrollback buffer” which you can find under Preferences > Profiles > Terminal or you can just pump up number of lines that you want to have in history in the same place.

I have encountered the same problem and in my case it was happening as a result of this problem:

I had the controllers defined in a separate module (called 'myApp.controllers') and injected to the main app module (called 'myApp') like this:

angular.module('myApp', ['myApp.controllers'])

A colleague pushed another controller module in a separate file but with the exact same name as mine (i.e. 'myApp.controllers' ) which caused this error. I think because Angular got confused between those controller modules. However the error message was not very helpful in discovering what is going wrong.

In CentOS 6 and Solr 4.4.0

I had to comp some lib files to get this error addressed

cp ~/solr-4.4.0/example/lib/ext/* /usr/share/tomcat6/lib/

Add pointer-events: none; to the overlay.

Original answer: My suggestion would be that you could capture the click event with the overlay, hide the overlay, then refire the click event, then display the overlay again. I'm not sure if you'd get a flicker effect though.

[Update] Exactly this problem and exactly my solution just appeared in this post: "Forwarding Mouse Events Through Layers". I know its probably a little late for the OP, but for the sake of somebody having this problem in the future, I though I would include it.

Both would return true on Unix systems - in Unix everything is a file, including directories. But to test if that name is taken, you should check both. There might be a regular file named 'foo', which would prevent you from creating a directory name 'foo'.

You can use the JsonTextReader to read the JSON and iterate over the tokens:

using (var reader = new JsonTextReader(new StringReader(jsonText)))
{
    while (reader.Read())
    {
        Console.WriteLine("{0} - {1} - {2}", 
                          reader.TokenType, reader.ValueType, reader.Value);
    }
}

There's a better way to handle it using Native MongoDB code in Mongoose.

exports.getUsers = function(req, res, next) {

    var usersProjection = { 
        __v: false,
        _id: false
    };

    User.find({}, usersProjection, function (err, users) {
        if (err) return next(err);
        res.json(users);
    });    
}

http://docs.mongodb.org/manual/reference/method/db.collection.find/

Note:

var usersProjection

The list of objects listed here will not be returned / printed.

jQuery('input[name="inputName"]:checked').val()

Is there any way you could programatically apply a class to the object?

<object class="hasparams">

then do

object.hasparams

You can have multiple CTEs in one query, as well as reuse a CTE:

WITH    cte1 AS
        (
        SELECT  1 AS id
        ),
        cte2 AS
        (
        SELECT  2 AS id
        )
SELECT  *
FROM    cte1
UNION ALL
SELECT  *
FROM    cte2
UNION ALL
SELECT  *
FROM    cte1

Note, however, that SQL Server may reevaluate the CTE each time it is accessed, so if you are using values like RAND(), NEWID() etc., they may change between the CTE calls.

Edit line 197 and 198 of jquery.fancybox.css:

}

1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

Use Pry (GitHub).

Install via:

$ gem install pry
$ pry

Then add:

require 'pry'; binding.pry

into your program.

As of pry 0.12.2 however, there are no navigation commands such as next, break, etc. Some other gems additionally provide this, see for example pry-byedebug.

With Java 7, it's as simple as:

final String EoL = System.getProperty("line.separator");
List<String> lines = Files.readAllLines(Paths.get(fileName),
        Charset.defaultCharset());

StringBuilder sb = new StringBuilder();
for (String line : lines) {
    sb.append(line).append(EoL);
}
final String content = sb.toString();

However, it does havea few minor caveats (like handling files that does not fit into the memory).

I would suggest taking a look on corresponding section in the official Java tutorial (that's also the case if you have a prior Java).

As others pointed out, you might find sime 3rd party libraries useful (like Apache commons I/O or Guava).

One option is to use do.call():

 > do.call(rbind, a)
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

Simplest solution:

iOS 10 & up, Swift:

button.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.titleLabel?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)
button.imageView?.transform = CGAffineTransform(scaleX: -1.0, y: 1.0)

Before iOS 10, Swift/Obj-C:

button.transform = CGAffineTransformMakeScale(-1.0, 1.0);
button.titleLabel.transform = CGAffineTransformMakeScale(-1.0, 1.0);
button.imageView.transform = CGAffineTransformMakeScale(-1.0, 1.0);

iOS 9 & up, Swift: (Recommended)

button.semanticContentAttribute = .forceRightToLeft

Referring to the answer of jnml, you could prevent new instances of Base type by not exporting the Base type at all (i.e. write it lowercase). If needed, you may make an exportable interface that has a method that returns a base type. This interface could be used in functions from the outside that deal with Bases, i.e.

package a

type base int

const (
    A base = iota
    C
    T
    G
)


type Baser interface {
    Base() base
}

// every base must fulfill the Baser interface
func(b base) Base() base {
    return b
}


func(b base) OtherMethod()  {
}

package main

import "a"

// func from the outside that handles a.base via a.Baser
// since a.base is not exported, only exported bases that are created within package a may be used, like a.A, a.C, a.T. and a.G
func HandleBasers(b a.Baser) {
    base := b.Base()
    base.OtherMethod()
}


// func from the outside that returns a.A or a.C, depending of condition
func AorC(condition bool) a.Baser {
    if condition {
       return a.A
    }
    return a.C
}

Inside the main package a.Baser is effectively like an enum now. Only inside the a package you may define new instances.

All these answers with .ReadAllBytes(). Another, similar (I won't say duplicate, since they were trying to refactor their code) question was asked on SO here: Best way to read a large file into a byte array in C#?

A comment was made on one of the posts regarding .ReadAllBytes():

File.ReadAllBytes throws OutOfMemoryException with big files (tested with 630 MB file 
and it failed) – juanjo.arana Mar 13 '13 at 1:31

A better approach, to me, would be something like this, with BinaryReader:

public static byte[] FileToByteArray(string fileName)
{
    byte[] fileData = null;

    using (FileStream fs = File.OpenRead(fileName)) 
    { 
        var binaryReader = new BinaryReader(fs); 
        fileData = binaryReader.ReadBytes((int)fs.Length); 
    }
    return fileData;
}

But that's just me...

Of course, this all assumes you have the memory to handle the byte[] once it is read in, and I didn't put in the File.Exists check to ensure the file is there before proceeding, as you'd do that before calling this code.

For those who want single command SQL query for that:

INSERT INTO TABLE002 
(COL001_MEM_ID, COL002_MEM_NAME, COL002_MEM_ADD, COL002_CREATE_USER_C, COL002_CREATE_S)
SELECT COL001_MEM_ID, COL001_MEM_NAME, COL001_MEM_ADD, COL001_CREATE_USER_C, COL001_CREATE_S
FROM TABLE001;

This query will copy data from TABLE001 to TABLE002 and we assume that both columns had different column names.

Column names are mapped one-to-one like:

COL001_MEM_ID -> COL001_MEM_ID

COL001_MEM_NAME -> COL002_MEM_NAME

COL001_MEM_ADD -> COL002_MEM_ADD

COL001_CREATE_USER_C -> COL002_CREATE_USER_C

COL002_CREATE_S -> COL002_CREATE_S

You can also specify where clause, if you need some condition.

If you are using express, you can use cors middleware as follows:

var express = require('express')
var cors = require('cors')
var app = express()

app.use(cors())

Active Directory is a database based system that provides authentication, directory, policy, and other services in a Windows environment

LDAP (Lightweight Directory Access Protocol) is an application protocol for querying and modifying items in directory service providers like Active Directory, which supports a form of LDAP.

Short answer: AD is a directory services database, and LDAP is one of the protocols you can use to talk to it.

If anyone else that finds this question and needs a dynamic solution for this where you have an undefined number of columns to transpose to and not exactly 3, you can find a nice solution here: https://github.com/jumpstarter-io/colpivot

Use font property of UILabel:

label.font = UIFont(name:"HelveticaNeue-Bold", size: 16.0)

or use default system font to bold text:

label.font = UIFont.boldSystemFont(ofSize: 16.0)

You could try this:

string input = "lala.bla";
output = input.Split('.').Last();

Here is another variation on the Bootstrap 4.1 Navbar with multi-level dropdown. This one uses minimal CSS for the submenu, and can be re-positioned as desired:

https://www.codeply.com/go/nG6iMAmI2X

.dropdown-submenu {
  position: relative;
}

.dropdown-submenu .dropdown-menu {
  top: 0;
  left: 100%;
  margin-top: -1px;
}

jQuery to control display of submenus:

$('.dropdown-submenu > a').on("click", function(e) {
    var submenu = $(this);
    $('.dropdown-submenu .dropdown-menu').removeClass('show');
    submenu.next('.dropdown-menu').addClass('show');
    e.stopPropagation();
});

$('.dropdown').on("hidden.bs.dropdown", function() {
    // hide any open menus when parent closes
    $('.dropdown-menu.show').removeClass('show');
});

See this answer for activating the Bootstrap 4 submenus on hover

I use a mixed approach to cancel a task.

• Firstly, I'm trying to Cancel it politely with using the Cancellation.
• If it's still running (e.g. due to a developer's mistake), then misbehave and kill it using an old-school Abort method.

Checkout an example below:

private CancellationTokenSource taskToken;
private AutoResetEvent awaitReplyOnRequestEvent = new AutoResetEvent(false);

void Main()
{
    // Start a task which is doing nothing but sleeps 1s
    LaunchTaskAsync();
    Thread.Sleep(100);
    // Stop the task
    StopTask();
}

/// <summary>
///     Launch task in a new thread
/// </summary>
void LaunchTaskAsync()
{
    taskToken = new CancellationTokenSource();
    Task.Factory.StartNew(() =>
        {
            try
            {   //Capture the thread
                runningTaskThread = Thread.CurrentThread;
                // Run the task
                if (taskToken.IsCancellationRequested || !awaitReplyOnRequestEvent.WaitOne(10000))
                    return;
                Console.WriteLine("Task finished!");
            }
            catch (Exception exc)
            {
                // Handle exception
            }
        }, taskToken.Token);
}

/// <summary>
///     Stop running task
/// </summary>
void StopTask()
{
    // Attempt to cancel the task politely
    if (taskToken != null)
    {
        if (taskToken.IsCancellationRequested)
            return;
        else
            taskToken.Cancel();
    }

    // Notify a waiting thread that an event has occurred
    if (awaitReplyOnRequestEvent != null)
        awaitReplyOnRequestEvent.Set();

    // If 1 sec later the task is still running, kill it cruelly
    if (runningTaskThread != null)
    {
        try
        {
            runningTaskThread.Join(TimeSpan.FromSeconds(1));
        }
        catch (Exception ex)
        {
            runningTaskThread.Abort();
        }
    }
}

You can either use a module like Math::Round:

use Math::Round;
my $rounded = round( $float );

Or you can do it the crude way:

my $rounded = sprintf "%.0f", $float;

A non-JIT compiler takes source code and transforms it into machine specific byte code at compile time. A JIT compiler takes machine agnostic byte code that was generated at compile time and transforms it into machine specific byte code at run time. The JIT compiler that Java uses is what allows a single binary to run on a multitude of platforms without modification.

In easy language, both versions are absolutely the same. Only difference is:

• min.js is for websites (online)

• .js is for developers, guys who needs to read, learn about or/and understand jquery codes, for ie plugin development (offline, local work).

You should look at the with binding, as well as controlsDescendantBindings http://knockoutjs.com/documentation/custom-bindings-controlling-descendant-bindings.html

I had luck with this:

  <Route
    path="/example"
    component={() => {
    global.window && (global.window.location.href = 'https://example.com');
    return null;
    }}
/>

As astander has mentioned, you can do that with a UDF. However, for large sets using a scalar function (as oppoosed to a inline-table function) the performance will stink as the function is evaluated row-by-row. As an alternative, you could expose the same results via a stored procedure executing a fixed query with placeholders which substitutes in your parameter values.

(Here's a somewhat dated but still relevant article on row-by-row processing for scalar UDFs.)

Edit: comments re. degrading performance adjusted to make it clear this applies to scalar UDFs.

I'm with a similar problem, but, in filenames of a file I'm compressing with apache commons. So, i resolved it with this command:

convmv --notest -f cp1252 -t utf8 * -r

it works very well for me. Hope it help anyone ;)

There is no need to set the environment for running the code on javascript,python,etc in visual studio code what you have to do is just install the Code Runner Extension and then just select the part of the code you want to run and hit the run button present on the upper right corner.

No.

You get charged for:

1. Online time
2. Storage space (assumably you store the image on S3 [EBS])
3. Elastic IP addresses
4. Bandwidth

So... if you stop the EC2 instance you will only have to pay for the storage of the image on S3 (assuming you store an image ofcourse) and any IP addresses you've reserved.

UPDATE table_name
SET field_name = '0'
WHERE field_name IS Null

You can also use array_keys() . Newbie friendly:

$keys = array_keys($arrayToWalk);
$arraySize = count($arrayToWalk); 

for($i=0; $i < $arraySize; $i++) {
    echo '<option value="' . $keys[$i] . '">' . $arrayToWalk[$keys[$i]] . '</option>';
}

It means that the query you wrote returns more than one element(result) while your code expects a single result.

Thanks to all the investigations of Lance, I could find a solution to my problem. It possibly had to do with my ISP.

To summarize:

• Internet sites were displayed in the Intranet zone
• Because of that the document mode was defaulted to 5 or 7 instead of Edge

I unchecked the "Automatically detect settings" in the Local Area Network Settings (found in "Internet Options" > Connections > LAN Settings.

Now the sites are correctly marked as Internet sites (instead of Intranet sites).

• For the earlier versions:

  history.push('/path', yourData);
  

  And get the data in the related component just like below:

  this.props.location.state // it is equal to yourData
  

• For the newer versions the above way works well but there is a new way:

  history.push({
    pathname: '/path',
    customNameData: yourData,
  });
  

  And get the data in the related component just like below:

  this.props.location.customNameData // it is equal to yourData
  

Hint: the state key name was used in the earlier versions and for newer versions, you can use your custom name to pass data and using state name is not essential.

For those who are visiting this old thread here is a package I find to be good.

https://www.npmjs.org/package/config

I use a solution that is similar to that of David above, but with an additional twist if some rows should be excluded from the count. This assumes that [UserAccountKey] is never null.

-- subtract an extra 1 if null was ranked within the partition,
-- which only happens if there were rows where [Include] <> 'Y'
dense_rank() over (
  partition by [Mth] 
  order by case when [Include] = 'Y' then [UserAccountKey] else null end asc
) 
+ dense_rank() over (
  partition by [Mth] 
  order by case when [Include] = 'Y' then [UserAccountKey] else null end desc
)
- max(case when [Include] = 'Y' then 0 else 1 end) over (partition by [Mth])
- 1

An SQL Fiddle with an extended example can be found here.

       if(props.userType){
          var data = []
          Object.keys(props.userType).map(i=>{
                data.push(props.userType[i])
          })
          setService(data)
        }

To get each sum in a separate column:

Select SUM(IF(CPaymentType='Check', CAmount, 0)) as PaymentAmountCheck,
       SUM(IF(CPaymentType='Cash', CAmount, 0)) as PaymentAmountCash
from TableOrderPayment
where CPaymentType IN ('Check','Cash') 
and CDate<=SYSDATETIME() 
and CStatus='Active';

Using two datasources you need their own transaction managers.

@Configuration
public class MySqlDBConfig {
    @Bean
    @Primary
    @ConfigurationProperties(prefix="datasource.test.mysql")
    public DataSource mysqlDataSource(){
         return DataSourceBuilder
                 .create()
                 .build();
    }

    @Bean("mysqlTx")
    public DataSourceTransactionManager mysqlTx() {
        return new DataSourceTransactionManager(mysqlDataSource());
    }

    // same for another DS
}

And then use it accordingly within @Transaction

@Transactional("mysqlTx")
@Repository
public interface UserMysqlDao extends CrudRepository<UserMysql, Integer>{
    public UserMysql findByName(String name);
}

Option #1: Try invalidateOptionsMenu(). I don't know if this will force an immediate redraw of the action bar or not.

Option #2: See if getActionView() returns anything for the affected MenuItem. It is possible that showAsAction simply automatically creates action views for you. If so, you can presumably enable/disable that View.

I can't seem to find a way to get the currently set Menu to manipulate it except for in onPrepareOptionMenu.

You can hang onto the Menu object you were handed in onCreateOptionsMenu(). Quoting the docs:

You can safely hold on to menu (and any items created from it), making modifications to it as desired, until the next time onCreateOptionsMenu() is called.

Forgot to put the variable in the sql statement without quotations.

 $update_query = 
      "UPDATE db.tablename SET insert_time=NOW() WHERE username='" .$somename."'";

The JUnit assertEquals(obj1, obj2) does indeed call obj1.equals(obj2).

There's also assertSame(obj1, obj2) which does obj1 == obj2 (i.e., verifies that obj1 and obj2 are referencing the same instance), which is what you're trying to avoid.

So you're fine.

If you encounter this apparent index corruption in a running system, you can work around it by deleting all files called segments.gen. It is advisory only, and Lucene can recover correctly without it.

From ElasticSearch Blog

There is a tipping point at which it's beneficial to have more than one css file.

A site with 1M+ pages, which the average user is likely to only ever see say 5 of, might have a stylesheet of immense proportions, so trying to save the overhead of a single additional request per page load by having a massive initial download is false economy.

Stretch the argument to the extreme limit - it's like suggesting that there should be one large stylesheet maintained for the entire web. Clearly nonsensical.

The tipping point will be different for each site though so there's no hard and fast rule. It will depend upon the quantity of unique css per page, the number of pages, and the number of pages the average user is likely to routinely encounter while using the site.

The correct answer, is to use a class and put the value inside the class, this lets you pass by reference exactly as you desire.

class Thing:
  def __init__(self,a):
    self.a = a
def dosomething(ref)
  ref.a += 1

t = Thing(3)
dosomething(t)
print("T is now",t.a)

So here is the controller code.

public IActionResult AddURLTest()
{
    return ViewComponent("AddURL");
}

You can load it using JQuery load method.

$(document).ready (function(){
    $("#LoadSignIn").click(function(){
        $('#UserControl').load("/Home/AddURLTest");
    });
});

Might not be the case, but this was the solution to my "pre-receive hook declined" error:

There are some repositories that only allow modifications through Pull Request. This means that you have to

1. Create a new branch taking as base the branch that you want to push your changes to.
2. Commit and push your changes to the new branch.
3. Open a Pull Request to merge your branch with the original one.

The Rob Evans anwser works correctly for me but when I use request.abort(), it occurs to throw a socket hang up error which stays unhandled.

I had to add an error handler for the request object :

var options = { ... }
var req = http.request(options, function(res) {
  // Usual stuff: on(data), on(end), chunks, etc...
}

req.on('socket', function (socket) {
    socket.setTimeout(myTimeout);  
    socket.on('timeout', function() {
        req.abort();
    });
}

req.on('error', function(err) {
    if (err.code === "ECONNRESET") {
        console.log("Timeout occurs");
        //specific error treatment
    }
    //other error treatment
});

req.write('something');
req.end();

Addendum to @sjngm's answer:

They both also ignore whitespace:

var foo = " 3 "; console.log(parseInt(foo)); // 3 console.log(Number(foo)); // 3

It is not exactly correct. As sjngm wrote parseInt parses string to first number. It is true. But the problem is when you want to parse number separated with whitespace ie. "12 345". In that case
parseInt("12 345") will return 12 instead of 12345. So to avoid that situation you must trim whitespaces before parsing to number. My solution would be:

     var number=parseInt("12 345".replace(/\s+/g, ''),10);

Notice one extra thing I used in parseInt() function. parseInt("string",10) will set the number to decimal format. If you would parse string like "08" you would get 0 because 8 is not a octal number.Explanation is here

There's a far more simpler solution to tackle this.

The reason why you get ValueError: Index contains duplicate entries, cannot reshape is because, once you unstack "Location", then the remaining index columns "id" and "date" combinations are no longer unique.

You can avoid this by retaining the default index column (row #) and while setting the index using "id", "date" and "location", add it in "append" mode instead of the default overwrite mode.

So use,

e.set_index(['id', 'date', 'location'], append=True)

Once this is done, your index columns will still have the default index along with the set indexes. And unstack will work.

Let me know how it works out.

A view is a virtual table. A view consists of rows and columns just like a table. The difference between a view and a table is that views are definitions built on top of other tables (or views), and do not hold data themselves. If data is changing in the underlying table, the same change is reflected in the view. A view can be built on top of a single table or multiple tables. It can also be built on top of another view. In the SQL Create View page, we will see how a view can be built.

Views offer the following advantages:

1. Ease of use: A view hides the complexity of the database tables from end users. Essentially we can think of views as a layer of abstraction on top of the database tables.

2. Space savings: Views takes very little space to store, since they do not store actual data.

3. Additional data security: Views can include only certain columns in the table so that only the non-sensitive columns are included and exposed to the end user. In addition, some databases allow views to have different security settings, thus hiding sensitive data from prying eyes.

Look for keys (first word of line) in file2 that are also in file1.
Step 1: fill array a with the first words of file 1:

awk '{a[$1];}' file1

Step 2: Fill array a and ignore file 2 in the same command. For this check the total number of records until now with the number of the current input file.

awk 'NR==FNR{a[$1]}' file1 file2

Step 3: Ignore actions that might come after } when parsing file 1

awk 'NR==FNR{a[$1];next}' file1 file2 

Step 4: print key of file2 when found in the array a

awk 'NR==FNR{a[$1];next} $1 in a{print $1}' file1 file2

In 32 bit format system the hexadecimal value 0xff represents 00000000000000000000000011111111 that is 255(15*16^1+15*16^0) in decimal. and the bitwise & operator masks the same 8 right most bits as in first operand.

If you have a browser that doesn't support the calc expression, it's not hard to mimic with jQuery:

$('#yourEl').css('width', '100%').css('width', '-=100px');

It's much easier to let jQuery handle the relative calculation than doing it yourself.

The file is created wherever the root of the python interpreter was started.

Eg, you start python in /home/user/program, then the file "test.py" would be located at /home/user/program/test.py

A single way to remove sessions is setting it to null;

guys i got a new way get system time. though its lengthy and is full of silly works but in this way you can get system time in integer format.

#include <stdio.h>
#include <stdlib.h>

int main()
{
    FILE *fp;
    char hc1,hc2,mc1,mc2;
    int hi1,hi2,mi1,mi2,hour,minute;
    system("echo %time% >time.txt");
    fp=fopen("time.txt","r");
    if(fp==NULL)
       exit(1) ;
    hc1=fgetc(fp);
    hc2=fgetc(fp);
    fgetc(fp);
    mc1=fgetc(fp);
    mc2=fgetc(fp);
    fclose(fp);
    remove("time.txt");
    hi1=hc1;
    hi2=hc2;
    mi1=mc1;
    mi2=mc2;
    hi1-=48;
    hi2-=48;
    mi1-=48;
    mi2-=48;
    hour=hi1*10+hi2;
    minute=mi1*10+mi2;
    printf("Current time is %d:%d\n",hour,minute);
    return 0;
}

This is the easiest way I can figure out:

#!/usr/bin/python3
for i in range(97, 123):
    print("{:c}".format(i), end='')

So, 97 to 122 are the ASCII number equivalent to 'a' to and 'z'. Notice the lowercase and the need to put 123, since it will not be included).

In print function make sure to set the {:c} (character) format, and, in this case, we want it to print it all together not even letting a new line at the end, so end=''would do the job.

The result is this: abcdefghijklmnopqrstuvwxyz

for me the "workaround" solution was to remove the "_normal" from the end of the string

try to override toString() method as you want that the element will be printend. so the method to print can be this:

for(int i=0;i<list.size();i++){
    System.out.println(list.get(i).toString());
} 

Do something like this, which also prevents SQL injection attacks

statement = con.prepareStatement("SELECT * from employee WHERE  userID = ?");
statement.setString(1, userID);
ResultSet rs = statement.executeQuery();

If you know the actual type, then just:

SomeType typed = (SomeType)obj;
typed.MyFunction();

If you don't know the actual type, then: not really, no. You would have to instead use one of:

• reflection
• implementing a well-known interface
• dynamic

For example:

// reflection
obj.GetType().GetMethod("MyFunction").Invoke(obj, null);

// interface
IFoo foo = (IFoo)obj; // where SomeType : IFoo and IFoo declares MyFunction
foo.MyFunction();

// dynamic
dynamic d = obj;
d.MyFunction();

This is Andy's solution. I just addressed User2357112's concern and gave it meaningful variable names. I'm a Python rookie and preferred these functions.

    if howMany <1:
        return ''
    else:
        return aString[-howMany:]

def mid(aString, startChar, howMany):
    if howMany < 1:
        return ''
    else:
        return aString[startChar:startChar+howMany]

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

I do not have a PhD, nor any other kind of degree neither in CS nor math nor indeed any other field. I have no prior experience with Scala nor any other similar language. I have no experience with even remotely comparable type systems. In fact, the only language that I have more than just a superficial knowledge of which even has a type system is Pascal, not exactly known for its sophisticated type system. (Although it does have range types, which AFAIK pretty much no other language has, but that isn't really relevant here.) The other three languages I know are BASIC, Smalltalk and Ruby, none of which even have a type system.

And yet, I have no trouble at all understanding the signature of the map function you posted. It looks to me like pretty much the same signature that map has in every other language I have ever seen. The difference is that this version is more generic. It looks more like a C++ STL thing than, say, Haskell. In particular, it abstracts away from the concrete collection type by only requiring that the argument is IterableLike, and also abstracts away from the concrete return type by only requiring that an implicit conversion function exists which can build something out of that collection of result values. Yes, that is quite complex, but it really is only an expression of the general paradigm of generic programming: do not assume anything that you don't actually have to.

In this case, map does not actually need the collection to be a list, or being ordered or being sortable or anything like that. The only thing that map cares about is that it can get access to all elements of the collection, one after the other, but in no particular order. And it does not need to know what the resulting collection is, it only needs to know how to build it. So, that is what its type signature requires.

So, instead of

map :: (a ? b) ? [a] ? [b]

which is the traditional type signature for map, it is generalized to not require a concrete List but rather just an IterableLike data structure

map :: (IterableLike i, IterableLike j) ? (a ? b) ? i ? j

which is then further generalized by only requiring that a function exists that can convert the result to whatever data structure the user wants:

map :: IterableLike i ? (a ? b) ? i ? ([b] ? c) ? c

I admit that the syntax is a bit clunkier, but the semantics are the same. Basically, it starts from

def map[B](f: (A) ? B): List[B]

which is the traditional signature for map. (Note how due to the object-oriented nature of Scala, the input list parameter vanishes, because it is now the implicit receiver parameter that every method in a single-dispatch OO system has.) Then it generalized from a concrete List to a more general IterableLike

def map[B](f: (A) ? B): IterableLike[B]

Now, it replaces the IterableLike result collection with a function that produces, well, really just about anything.

def map[B, That](f: A ? B)(implicit bf: CanBuildFrom[Repr, B, That]): That

Which I really believe is not that hard to understand. There's really only a couple of intellectual tools you need:

1. You need to know (roughly) what map is. If you gave only the type signature without the name of the method, I admit, it would be a lot harder to figure out what is going on. But since you already know what map is supposed to do, and you know what its type signature is supposed to be, you can quickly scan the signature and focus on the anomalies, like "why does this map take two functions as arguments, not one?"
2. You need to be able to actually read the type signature. But even if you have never seen Scala before, this should be quite easy, since it really is just a mixture of type syntaxes you already know from other languages: VB.NET uses square brackets for parametric polymorphism, and using an arrow to denote the return type and a colon to separate name and type, is actually the norm.
3. You need to know roughly what generic programming is about. (Which isn't that hard to figure out, since it's basically all spelled out in the name: it's literally just programming in a generic fashion).

None of these three should give any professional or even hobbyist programmer a serious headache. map has been a standard function in pretty much every language designed in the last 50 years, the fact that different languages have different syntax should be obvious to anyone who has designed a website with HTML and CSS and you can't subscribe to an even remotely programming related mailinglist without some annoying C++ fanboy from the church of St. Stepanov explaining the virtues of generic programming.

Yes, Scala is complex. Yes, Scala has one of the most sophisticated type systems known to man, rivaling and even surpassing languages like Haskell, Miranda, Clean or Cyclone. But if complexity were an argument against success of a programming language, C++ would have died long ago and we would all be writing Scheme. There are lots of reasons why Scala will very likely not be successful, but the fact that programmers can't be bothered to turn on their brains before sitting down in front of the keyboard is probably not going to be the main one.

@petah and Acrylic DNS Proxy is the best answer, and at the end he references the ability to do multi-site using an Apache which @jeremyasnyder describes a little further down...

... however, in our case we're testing a multi-tenant hosting system and so most domains we want to test go to the same virtualhost, while a couple others are directed elsewhere.

So in our case, you simply use regex wildcards in the ServerAlias directive, like so...

So ... more digging, with the result. It seems that although I ran one process normal and one "As Administrator", I had UAC off. Turning UAC to medium allowed me to see different results. Basically, it all boils down to integrity levels, which are 5.

Browsers, for example, run at Low Level (1), while services (System user) run at System Level (4). Everything is very well explained in Windows Integrity Mechanism Design . When UAC is enabled, processes are created with Medium level (SID S-1-16-8192 AKA 0x2000 is added) while when "Run as Administrator", the process is created with High Level (SID S-1-16-12288 aka 0x3000).

So the correct ACCESS_TOKEN for a normal user (Medium Integrity level) is:

0:000:x86> !token

For each iteration of the ng-repeat loop, line is a reference to an object in your array. Therefore, to preview the value, use {{line.text}}.

Similarly, to databind to the text, databind to the same: ng-model="line.text". You don't need to use value when using ng-model (actually you shouldn't).

Fiddle.

Just in case anyone wants to, IMHO the best solution using CSS is by a flexbox.

Here is an example:

.kw-dvp-HorizonalButton {_x000D_
    color: #0078d7;_x000D_
    display:flex;_x000D_
    flex-wrap:nowrap;_x000D_
    align-items:center;_x000D_
}_x000D_
.kw-dvp-HorizonalButton:before, .kw-dvp-HorizonalButton:after {_x000D_
    background-color: #0078d7;_x000D_
    content: "";_x000D_
    display: inline-block;_x000D_
    float:left;_x000D_
    height:1px;_x000D_
}_x000D_
.kw-dvp-HorizonalButton:before {_x000D_
    order:1;_x000D_
    flex-grow:1;_x000D_
    margin-right:8px;_x000D_
}_x000D_
.kw-dvp-HorizonalButton:after {_x000D_
    order: 3;_x000D_
    flex-grow: 1;_x000D_
    margin-left: 8px;_x000D_
}_x000D_
.kw-dvp-HorizonalButton * {_x000D_
    order: 2;_x000D_
}

    <div class="kw-dvp-HorizonalButton">_x000D_
        <span>hello</span>_x000D_
    </div>

This should always result in a perfectly centered aligned content with a line to the left and right, with an easy to control margin between the line and your content.

It creates a line element before and after your top control and set them to order 1,3 in your flex container while setting your content as order 2 (go in the middle). giving the before/after a grow of 1 will make them consume the most vacant space equally while keeping your content centered.

Hope this helps!

You should use the PHP function in_array (see http://php.net/manual/en/function.in-array.php).

if (!in_array($value, $array))
{
    $array[] = $value; 
}

This is what the documentation says about in_array:

Returns TRUE if needle is found in the array, FALSE otherwise.

As of PHP 7.x, you can use the following:

$aDate = new \DateTime('@'.(time()));
$bDate = new \DateTime('@'.(time() - 3600));

$aDate <=> $bDate; // => 1, `$aDate` is newer than `$bDate`

I found one solution for assign variables to COLUMN or TABLE:

conn = sqlite3.connect('database.db')
cursor=conn.cursor()
z="Cash_payers"   # bring results from Table 1 , Column: Customers and COLUMN 
# which are pays cash
sorgu_y= Customers #Column name
query1="SELECT  * FROM  Table_1 WHERE " +sorgu_y+ " LIKE ? "
print (query1)
query=(query1)
cursor.execute(query,(z,))

Don't forget input one space between the WHERE and double quotes and between the double quotes and LIKE

The good folks at HubSpot have a resource where you can find pure Javascript methodologies for achieving a lot of jQuery goodness - including ready

http://youmightnotneedjquery.com/#ready

function ready(fn) {
  if (document.readyState != 'loading'){
    fn();
  } else if (document.addEventListener) {
    document.addEventListener('DOMContentLoaded', fn);
  } else {
    document.attachEvent('onreadystatechange', function() {
      if (document.readyState != 'loading')
        fn();
    });
  }
}

example inline usage:

ready(function() { alert('hello'); });

rand(3..10)

Kernel#rand

When max is a Range, rand returns a random number where range.member?(number) == true.

If you'd like you components to remain easily testable you should wrap the global window object in an Angular Service:

import { Injectable } from '@angular/core';

@Injectable()
export class WindowService {

  get windowRef() {
    return window;
  }

}

You can then inject it like any other service:

constructor(
    private windowService: WindowService
) { }

And consume...

  ngOnInit() {
      const width= this.windowService.windowRef.innerWidth;
  }

That's not possible. but you can use an Object Mapper like AutoMapper

Example:

class A
{
    public int IntProp { get; set; }
}
class B
{
    public int IntProp { get; set; }
    public string StrProp { get; set; }
}

In global.asax or application startup:

AutoMapper.Mapper.CreateMap<A, B>();

Usage:

var b = AutoMapper.Mapper.Map<B>(a);

It's easily configurable via a fluent API.

For a bit more flexibility than with micronyks answer, you can do it like that:

1. In your template, add #myIdentifier to the element you want to obtain the width from. Example:

<p #myIdentifier>
  my-component works!
</p>

2. In your controller, you can use this with @ViewChild('myIdentifier') to get the width:

import {AfterViewInit, Component, ElementRef, OnInit, ViewChild} from '@angular/core';

@Component({
  selector: 'app-my-component',
  templateUrl: './my-component.component.html',
  styleUrls: ['./my-component.component.scss']
})
export class MyComponentComponent implements AfterViewInit {

  constructor() { }

  ngAfterViewInit() {
    console.log(this.myIdentifier.nativeElement.offsetWidth);
  }

  @ViewChild('myIdentifier')
  myIdentifier: ElementRef;

}

Security

About the security risk with ElementRef, like this, there is none. There would be a risk, if you would modify the DOM using an ElementRef. But here you are only getting DOM Elements so there is no risk. A risky example of using ElementRef would be: this.myIdentifier.nativeElement.onclick = someFunctionDefinedBySomeUser;. Like this Angular doesn't get a chance to use its sanitisation mechanisms since someFunctionDefinedBySomeUser is inserted directly into the DOM, skipping the Angular sanitisation.

You can also do something:

SELECT CAST(CAST(34512367.392 AS decimal(30,9)) AS NVARCHAR(100))

Output: 34512367.392000000

You had several issues with your code.

1) Missing a closing brace, }, within your rules.

2) In this case, there is no reason to use a function for the required rule. By default, the plugin can handle checkbox and radio inputs just fine, so using true is enough. However, this will simply do the same logic as in your original function and verify that at least one is checked.

3) If you also want only a maximum of two to be checked, then you'll need to apply the maxlength rule.

4) The messages option was missing the rule specification. It will work, but the one custom message would apply to all rules on the same field.

5) If a name attribute contains brackets, you must enclose it within quotes.

DEMO: http://jsfiddle.net/K6Wvk/

$(document).ready(function () {

    $('#formid').validate({ // initialize the plugin
        rules: {
            'test[]': {
                required: true,
                maxlength: 2
            }
        },
        messages: {
            'test[]': {
                required: "You must check at least 1 box",
                maxlength: "Check no more than {0} boxes"
            }
        }
    });

});

Be sure to have both objects created in controller: @post and @comment for the post, eg:

@post = Post.find params[:post_id]
@comment = Comment.new(:post=>@post)

Then in view:

<%= form_for([@post, @comment]) do |f| %>

Be sure to explicitly define the array in the form_for, not just comma separated like you have above.

Look here for the answer by TheMattster. I implemented it and it worked like a charm. In a nutshell, his solution suggests to add the COM dll as a resource to the project (so now it compiles into the project's dll), and upon the first run write it to a file (i.e. the dll file I wanted there in the first place).

The following is taken from his answer.

Step 1) Add the DLL as a resource (below as "Resources.DllFile"). To do this open project properties, select the resources tab, select "add existing file" and add the DLL as a resource.

Step 2) Add the name of the DLL as a string resource (below as "Resources.DllName").

Step 3) Add this code to your main form-load:

if (!File.Exists(Properties.Resources.DllName))
{
    var outStream = new StreamWriter(Properties.Resources.DllName, false);
    var binStream = new BinaryWriter(outStream.BaseStream);
    binStream.Write(Properties.Resources.DllFile);
    binStream.Close();
}

My problem was that not only I had to use the COM dll in my project, I also had to deploy it with my app using ClickOnce, and without being able to add reference to it in my project the above solution is practically the only one that worked.

• for VB: vbCrLf or vbNewLine
• for VB.NET: Environment.NewLine or vbCrLf or Constants.vbCrLf

The info for Environment.NewLine came from Cody Gray and J Vermeire

This answer is to give a better understanding of this warning

Deprecation warning is caused when you use moment to create time object, var today = moment();.

If this warning is okay with you then I have a simpler method.

Don't use date object from js use moment instead. For example use moment() to get the current date.

Or convert the js date object to moment date. You can simply do that specifying the format of your js date object.

ie, moment("js date", "js date format");

eg:

moment("2014 04 25", "YYYY MM DD");

(BUT YOU CAN ONLY USE THIS METHOD UNTIL IT'S DEPRECIATED, this may be depreciated from moment in the future)

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2
2        14         3
3        12         1
4        15         4
> X[X$Variable1!=11 & X$Variable1!=12, ]
  Variable1 Variable2

4        15         4
> X[ ! X$Variable1 %in% c(11,12), ]
  Variable1 Variable2

You can functionalize this however you like.

document.getElementById("serverTime").innerHTML = ...;

yourTextView.setTextColor(color);

Or, in your case: yourTextView.setTextColor(0xffbdbdbd);

Setting mongoose connect useUnifiedTopology: true option

  import mongoose from 'mongoose';

        const server = '127.0.0.1:27017'; // REPLACE WITH YOUR DB SERVER
        const database = 'DBName'; // REPLACE WITH YOUR DB NAME
        class Database {
          constructor() {
            this._connect();
          }
          _connect() {
            mongoose.Promise = global.Promise;
            // * Local DB SERVER *
            mongoose
              .connect(`mongodb://${server}/${database}`, {
                useNewUrlParser: true,
                useCreateIndex: true,
                useUnifiedTopology: true
              })
              .then(
                () => console.log(`mongoose version: ${mongoose.version}`),
                console.log('Database connection successful'),
              )
              .catch(err => console.error('Database connection error', err));   
          }
        }
        module.exports = new Database();

git diff -w HEAD origin/master path/to/file

Only change the line str1:=''; to str1:=' ';

You could add a span before the link with a specific class like so:

<div class="btn btn_red"><span class="icon"></span><a href="#">Crimson</a><span></span></div>

And then give that a specific width and a background image just like you are doing with the button itself.

.btn span.icon {
    background: url(imgs/icon.png) no-repeat;
    float: left;
    width: 10px;
    height: 40px;
}

I am no CSS guru but off the top of my head I think that should work.

You can have multiple <context:property-placeholder /> elements instead of explicitly declaring multiple PropertiesPlaceholderConfigurer beans.

You are comparing the addresses instead of the values.

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

$.get(str, function(data){ 
            var sary=data.split('|');
            document.getElementById("select1").options.length = 0;
            document.getElementById("select1").options[0] = new Option('Select a State');
            for(i=0;i<sary.length-1;i++){
                document.getElementById("select1").options[i+1] = new Option(sary[i]);
                document.getElementById("select1").options[i+1].value = sary[i];
            }
            });

Here is how I did.

public/index.html

I have added the generated favicon links.

...
<link rel="icon" type="image/png" sizes="32x32" href="%PUBLIC_URL%/path/to/favicon-32x32.png" />
<link rel="icon" type="image/png" sizes="16x16" href="%PUBLIC_URL%/path/to/favicon-16x16.png" />
<link rel="shortcut icon" href="%PUBLIC_URL%/path/to/favicon.ico" type="image/png/ico" />

webpack.config.js

new HTMLWebpackPlugin({
   template: '/path/to/index.html',
   favicon: '/path/to/favicon.ico',
})

Note

I use historyApiFallback in dev mode, but I didn't need to have any extra setup to get the favicon work nor on the server side.

According to the documentation:

newshape : int or tuple of ints

The new shape should be compatible with the original shape. If an integer, then the result will be a 1-D array of that length. One shape dimension can be -1. In this case, the value is inferred from the length of the array and remaining dimensions.
