You can try with Directory.GetFiles and fix your pattern

 string[] files = Directory.GetFiles(@"c:\", "*.txt");

 foreach (string file in files)
 {
    File.Copy(file, "....");
 }

 Or Move

 foreach (string file in files)
 {
    File.Move(file, "....");
 }

Simply add this to your java module's build.gradle. It'll create executable jar. It will include dependent libraries in archive.

jar {
  manifest { 
    attributes "Main-Class": "com.company.application.Main"
  }  

  from {
    configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
  }
}

This will result in [module_name]/build/libs/[module_name].jar file. I tested this with shell.

To add to already great and easy solution provided by Przemek315, the same config if you use Kotlin DSL:

tasks.test {
    useJUnitPlatform()
}

The level of version information given out by an Apache server can be configured by the ServerTokens setting in its configuration.

I believe there is also a setting that controls whether the version appears in server error pages, although I can't remember what it is off the top of my head. If you don't have direct access to the server, and the server administrator is competent and doesn't want you to know the version they're running... I think you may be SOL.

I tried using phyatt's AspectRatioPixmapLabel class, but experienced a few problems:

• Sometimes my app entered an infinite loop of resize events. I traced this back to the call of QLabel::setPixmap(...) inside the resizeEvent method, because QLabel actually calls updateGeometry inside setPixmap, which may trigger resize events...
• heightForWidth seemed to be ignored by the containing widget (a QScrollArea in my case) until I started setting a size policy for the label, explicitly calling policy.setHeightForWidth(true)
• I want the label to never grow more than the original pixmap size
• QLabel's implementation of minimumSizeHint() does some magic for labels containing text, but always resets the size policy to the default one, so I had to overwrite it

That said, here is my solution. I found that I could just use setScaledContents(true) and let QLabel handle the resizing. Of course, this depends on the containing widget / layout honoring the heightForWidth.

aspectratiopixmaplabel.h

#ifndef ASPECTRATIOPIXMAPLABEL_H
#define ASPECTRATIOPIXMAPLABEL_H

#include <QLabel>
#include <QPixmap>

class AspectRatioPixmapLabel : public QLabel
{

public:
    explicit AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent = 0);
    virtual int heightForWidth(int width) const;
    virtual bool hasHeightForWidth() { return true; }
    virtual QSize sizeHint() const { return pixmap()->size(); }
    virtual QSize minimumSizeHint() const { return QSize(0, 0); }
};

#endif // ASPECTRATIOPIXMAPLABEL_H

aspectratiopixmaplabel.cpp

#include "aspectratiopixmaplabel.h"

AspectRatioPixmapLabel::AspectRatioPixmapLabel(const QPixmap &pixmap, QWidget *parent) :
    QLabel(parent)
{
    QLabel::setPixmap(pixmap);
    setScaledContents(true);
    QSizePolicy policy(QSizePolicy::Maximum, QSizePolicy::Maximum);
    policy.setHeightForWidth(true);
    this->setSizePolicy(policy);
}

int AspectRatioPixmapLabel::heightForWidth(int width) const
{
    if (width > pixmap()->width()) {
        return pixmap()->height();
    } else {
        return ((qreal)pixmap()->height()*width)/pixmap()->width();
    }
}

Thanks for spotting this I was about to add strings thinking the same as you that they'd get added to end of collection. It appears the params are:

msg.to.Add(<MailAddress>) adds MailAddress to the end of the collection
msg.to.Add(<string>) add a list of emails to the collection

Slightly different actions depending on param type, I think this is pretty bad form i'd have prefered split methods AddStringList of something.

// read file and make object
let content = JSON.parse(fs.readFileSync('file.json', 'utf8'));
// edit or add property
content.expiry_date = 999999999999;
//write file
fs.writeFileSync('file.json', JSON.stringify(content));

This one works with NULL Values in Table and doesn't require substring operation at the end. COALESCE is not really well working with NULL values in table (if they will be there).

DECLARE @results VARCHAR(1000) = '' 
SELECT @results = @results + 
           ISNULL(CASE WHEN LEN(@results) = 0 THEN '' ELSE ',' END + [StudentId], '')
FROM Student WHERE condition = xyz

select @results

There are many options, for example:

import operator
index, value = max(enumerate(my_list), key=operator.itemgetter(1))

If your goal is to initialize the static variable in your header file (instead of a *.cpp file, which you may want if you are sticking to a "header only" idiom), then you can work around the initialization problem by using a template. Templated static variables can be initialized in a header, without causing multiple symbols to be defined.

See here for an example:

Static member initialization in a class template

Reading the file

import h5py

f = h5py.File(file_name, mode)

Studying the structure of the file by printing what HDF5 groups are present

for key in f.keys():
    print(key) #Names of the groups in HDF5 file.

Extracting the data

#Get the HDF5 group
group = f[key]

#Checkout what keys are inside that group.
for key in group.keys():
    print(key)

data = group[some_key_inside_the_group].value
#Do whatever you want with data

#After you are done
f.close()

A HashMap can hold any object as a value, even if it is another HashMap. Eclipse is suggesting that you declare the types because that is the recommended practice for Collections. under Java 5. You are free to ignore Eclipse's suggestions.

Under Java 5, an int (or any primitive type) will be autoboxed into an Integer (or other corresponding type) when you add it to a collection. Be careful with this though, as there are some catches to using autoboxing.

You're on the right track with using document.getElementById() as you have done for your first two text boxes. Use something like document.getElementById("textbox3") to retrieve the element. Then you can just set its value property: document.getElementById("textbox3").value = answer;

For the "Your answer is: --", I'd recommend wrapping the "--" in a <span/> (e.g. <span id="answerDisplay">--</span>). Then use document.getElementById("answerDisplay").textContent = answer; to display it.

Best way in python is use this link.

A small Python 3.5+ library for decoding ASP.NET viewstate.

First install that: pip install viewstate

>>> from viewstate import ViewState
>>> base64_encoded_viewstate = '/wEPBQVhYmNkZQ9nAgE='
>>> vs = ViewState(base64_encoded_viewstate)
>>> vs.decode()
('abcde', (True, 1))

No one touched on it yet but it is something that every PHP developer should be able to speak at length about: Why is register_globals bad?

Screenshot:

Widget _buildTextField() {
  final maxLines = 5;

  return Container(
    margin: EdgeInsets.all(12),
    height: maxLines * 24.0,
    child: TextField(
      maxLines: maxLines,
      decoration: InputDecoration(
        hintText: "Enter a message",
        fillColor: Colors.grey[300],
        filled: true,
      ),
    ),
  );
}

Arrays should only have entries with numerical keys (arrays are also objects but you really should not mix these).

If you convert an array to JSON, the process will only take numerical properties into account. Other properties are simply ignored and that's why you get an empty array as result. Maybe this more obvious if you look at the length of the array:

> AssocArray.length
0

What is often referred to as "associative array" is actually just an object in JS:

var AssocArray = {};  // <- initialize an object, not an array
AssocArray["a"] = "The letter A"

console.log("a = " + AssocArray["a"]); // "a = The letter A"
JSON.stringify(AssocArray); // "{"a":"The letter A"}"

Properties of objects can be accessed via array notation or dot notation (if the key is not a reserved keyword). Thus AssocArray.a is the same as AssocArray['a'].

Use:

  SELECT mt.name 
    FROM MY_TABLE mt
GROUP BY mt.name
  HAVING MAX(LENGTH(mt.name)) = 18

...assuming you know the length beforehand. If you don't, use:

  SELECT mt.name 
    FROM MY_TABLE mt
    JOIN (SELECT MAX(LENGTH(x.name) AS max_length
            FROM MY_TABLE x) y ON y.max_length = LENGTH(mt.name)

My solution would be create custom filter and use it:

app.filter('with', function() {
  return function(items, field) {
        var result = {};
        angular.forEach(items, function(value, key) {
            if (!value.hasOwnProperty(field)) {
                result[key] = value;
            }
        });
        return result;
    };
});

And in html:

 <div ng-repeat="(k,v) in items | with:'secId'">
        {{k}} {{v.pos}}
 </div>

This code (example) :

    Chronology ch1 = GregorianChronology.getInstance();     Chronology ch2 = ISOChronology.getInstance();      DateTime dt = new DateTime("2013-12-31T22:59:21+01:00",ch1);     DateTime dt2 = new DateTime("2013-12-31T22:59:21+01:00",ch2);      System.out.println(dt);     System.out.println(dt2);      boolean b = dt.equals(dt2);      System.out.println(b); 

Will print :

2013-12-31T16:59:21.000-05:00 2013-12-31T16:59:21.000-05:00 false 

You are probably comparing two DateTimes with same date but different Chronology.

You can create anonymous methods or lambda expressions:

Func<string, string> PrefixTrimmer = delegate(string x) {
    return x ?? "";
};
Func<string, string> PrefixTrimmer = x => x ?? "";

What about

lstCountry.Items[lstCountry.SelectedIndex].Text;

The question "what the Context is" is one of the most difficult questions in the Android universe.

Context defines methods that access system resources, retrieve application's static assets, check permissions, perform UI manipulations and many more. In essence, Context is an example of God Object anti-pattern in production.

When it comes to which kind of Context should we use, it becomes very complicated because except for being God Object, the hierarchy tree of Context subclasses violates Liskov Substitution Principle brutally.

This blog post (now from Wayback Machine) attempts to summarize Context classes applicability in different situations.

Let me copy the main table from that post for completeness:

+----------------------------+-------------+----------+---------+-----------------+-------------------+

1. An application CAN start an Activity from here, but it requires that a new task be created. This may fit specific use cases, but can create non-standard back stack behaviors in your application and is generally not recommended or considered good practice.
2. This is legal, but inflation will be done with the default theme for the system on which you are running, not what’s defined in your application.
3. Allowed if the receiver is null, which is used for obtaining the current value of a sticky broadcast, on Android 4.2 and above.

use String formatting

print("If there was a birth every 7 seconds, there would be: {} births".format(births))
 # Will replace "{}" with births

if you doing a toy project use:

print('If there was a birth every 7 seconds, there would be:' births'births) 

or

print('If there was a birth every 7 seconds, there would be: %d births' %(births))
# Will replace %d with births

export ROOT_DIR=<path/value>

Then use the variable, $(ROOT_DIR) in the Makefile.

You can set the Field Separator:

... | awk 'BEGIN {FS="\t"}; {print $1}'

Excellent read:

https://docs.freebsd.org/info/gawk/gawk.info.Field_Separators.html

I have found the above answer to be the best solution, but I don't like the leading space before the percent sign. I have seen somewhat complicated solutions, but I just use this Replace addition to the answer above instead of using other rounding solutions.

String.Format("Value: {0:P2}.", 0.8526).Replace(" %","%") // formats as 85.26% (varies by culture)

Please check "top" command then if your script or any are running please note 'PID'

It's not necessary to cast both of them. Result datatype for a division is always the one with the higher data type precedence. Thus the solution must be:

SELECT CAST(1 AS float) / 3

or

SELECT 1 / CAST(3 AS float)

First, create a directory(folder) in the root of your local repo that will contain the screenshots you want added. Let’s call the name of this directory screenshots. Place the images (JPEG, PNG, GIF,` etc) you want to add into this directory.

Android Studio Workspace Screenshot

Secondly, you need to add a link to each image into your README. So, if I have images named 1_ArtistsActivity.png and 2_AlbumsActivity.png in my screenshots directory, I will add their links like so:

 <img src="screenshots/1_ArtistsActivity.png" height="400" alt="Screenshot"/> <img src=“screenshots/2_AlbumsActivity.png" height="400" alt="Screenshot"/>

If you want each screenshot on a separate line, write their links on separate lines. However, it’s better if you write all the links in one line, separated by space only. It might actually not look too good but by doing so GitHub automatically arranges them for you.

Finally, commit your changes and push it!

You can also collect with an appropriate summing collector like Collectors#summingInt(ToIntFunction)

Returns a Collector that produces the sum of a integer-valued function applied to the input elements. If no elements are present, the result is 0.

For example

Stream<Obj> filtered = list.stream().filter(o -> o.field > 10);
int sum = filtered.collect(Collectors.summingInt(o -> o.field));

It can be opened using Visual Studio 2012.Follow the below path in VS after opening the project. View->Server Explorer->

To have a consistent flow of the images on different devices, you'd have to specify the width and height value for each carousel image item, for instance here in my example the image would take the full width but with a height of "400px" (you can specify your personal value instead)

<div class="item">
        <img src="image.jpg" style="width:100%; height: 400px;">
      </div>

__main__.py is used for python programs in zip files. The __main__.py file will be executed when the zip file in run. For example, if the zip file was as such:

test.zip
     __main__.py

and the contents of __main__.py was

import sys
print "hello %s" % sys.argv[1]

Then if we were to run python test.zip world we would get hello world out.

So the __main__.py file run when python is called on a zip file.

select * from tblFruit where
tblFruit_ID in (Select max(tblFruit_ID) FROM tblFruit group by tblFruit_FruitType)

Most modern languages are in varying degree both imperative and functional but to better understand functional programming, it will be best to take an example of pure functional language like Haskell in contrast of imperative code in not so functional language like java/C#. I believe it is always easy to explain by example, so below is one.

Functional programming: calculate factorial of n i.e n! i.e n x (n-1) x (n-2) x ...x 2 X 1

-- | Haskell comment goes like
-- | below 2 lines is code to calculate factorial and 3rd is it's execution  

factorial 0 = 1
factorial n = n * factorial (n - 1)
factorial 3

-- | for brevity let's call factorial as f; And x => y shows order execution left to right
-- | above executes as := f(3) as 3 x f(2) => f(2) as 2 x f(1) => f(1) as 1 x f(0) => f(0) as 1  
-- | 3 x (2 x (1 x (1)) = 6

Notice that Haskel allows function overloading to the level of argument value. Now below is example of imperative code in increasing degree of imperativeness:

//somewhat functional way
function factorial(n) {
  if(n < 1) {
     return 1;
  }
  return n * factorial(n-1);   
}
factorial(3);

//somewhat more imperative way
function imperativeFactor(n) {
  int f = 1;
  for(int i = 1; i <= n; i++) {
     f = f * i;
  }
  return f;
}

This read can be a good reference to understand that how imperative code focus more on how part, state of machine (i in for loop), order of execution, flow control.

The later example can be seen as java/C# lang code roughly and first part as limitation of the language itself in contrast of Haskell to overload the function by value (zero) and hence can be said it is not purist functional language, on the other hand you can say it support functional prog. to some extent.

Disclosure: none of the above code is tested/executed but hopefully should be good enough to convey the concept; also I would appreciate comments for any such correction :)

You can try this, see if it works for you.

Rather than choosing date from date picker, you can enable the date box using javascript & enter the required date, this would avoid excessive time required to traverse through all date elements till you reach one you require to select.

Code for from date

((JavascriptExecutor)driver).executeScript ("document.getElementById('fromDate').removeAttribute('readonly',0);"); // Enables the from date box

WebElement fromDateBox= driver.findElement(By.id("fromDate"));
fromDateBox.clear();
fromDateBox.sendKeys("8-Dec-2014"); //Enter date in required format

Code for to date

((JavascriptExecutor)driver).executeScript ("document.getElementById('toDate').removeAttribute('readonly',0);"); // Enables the from date box

WebElement toDateBox= driver.findElement(By.id("toDate"));
toDateBox.clear();
toDateBox.sendKeys("15-Dec-2014"); //Enter date in required format

I've come cross an issue with the implementation of this solution.

If you have a custom component you want to iterate through and you want to share the state it will not be available as the .map() scope does not recognize the general state() scope. I've come to this solution:

`

class RootComponent extends Component() {
    constructor(props) {
        ....
        this.customFunction.bind(this);
        this.state = {thisWorks: false}
        this.that = this;
    }
    componentDidMount() {
        ....
    }
    render() {
       let array = this.thatstate.map(() => { 
           <CustomComponent that={this.that} customFunction={this.customFunction}/>
       });

    }
    customFunction() {
        this.that.setState({thisWorks: true})
    }
}



class CustomComponent extend Component {

    render() {
        return <Button onClick={() => {this.props.customFunction()}}
    }
}

In constructor bind without this.that Every use of any function/method inside the root component should be used with this.that

1. There shouldn't be any problem (other than any general problems you might have with very large images).
2. If you're talking about adding multiple images to a single panel, I would use ImageIcons. For a single image, I would think about making a custom subclass of JPanel and overriding its paintComponent method to draw the image.
3. (see 2)

Insert bulk more than 7000000 record in 1 minutes in database(superfast query with calculation)

mysqli_query($cons, '
    LOAD DATA LOCAL INFILE "'.$file.'"
    INTO TABLE tablename
    FIELDS TERMINATED by \',\'
    LINES TERMINATED BY \'\n\'
    IGNORE 1 LINES
    (isbn10,isbn13,price,discount,free_stock,report,report_date)
     SET RRP = IF(discount = 0.00,price-price * 45/100,IF(discount = 0.01,price,IF(discount != 0.00,price-price * discount/100,@RRP))),
         RRP_nl = RRP * 1.44 + 8,
         RRP_bl = RRP * 1.44 + 8,
         ID = NULL
    ');
$affected = (int) (mysqli_affected_rows($cons))-1; 
$log->lwrite('Inventory.CSV to database:'. $affected.' record inserted successfully.');

RRP and RRP_nl and RRP_bl is not in csv but we are calculated that and after insert that.

Use the "MMMM" custom format specifier:

DateTime.Now.ToString("MMMM");

You probably want to use "eq" instead of "==". If you worry about some edge cases you may also want to check for undefined:

if (not defined $str) {

# this variable is undefined

}

The easiest way is to simply use the

stmt.setString(position, xml);

methods (for "small" strings which can be easily kept in Java memory), or

try {
  java.sql.Clob clob = 
    oracle.sql.CLOB.createTemporary(
      connection, false, oracle.sql.CLOB.DURATION_SESSION);

  clob.setString(1, xml);
  stmt.setClob(position, clob);
  stmt.execute();
}

// Important!
finally {
  clob.free();
}

I can confirm that this is not fixable by unregistering and registering the MSCOMCTRL.OCX like before. I have been trying to pin down which update is the source of the problem and it looks like it's either IE10 or IE10 in combination with some other update that's causing the problem. If I can get more time to invest in this I'll update my post but in the meantime uninstalling IE10 resolves the issue.

writelines() does not add line separators. You can alter the list of strings by using map() to add a new \n (line break) at the end of each string.

items = ['abc', '123', '!@#']
items = map(lambda x: x + '\n', items)
w.writelines(items)

It is common for comparison functions to return 0 on "equals", so that they can also return a negative number for "less than" and a positive number for "greater than". strcmp() and memcmp() work like this.

It is, however, idiomatic for zero to be false and nonzero to be true, because this is how the C flow control and logical boolean operators work. So it might be that the return values chosen for this function are fine, but it is the function's name that is in error (it should really just be called compare() or similar).

let restaurant = restaurants.find(element => element.restaurant.food == "chicken");

The find() method returns the value of the first element in the provided array that satisfies the provided testing function.

C is a very low-level language, so it permits you to create almost any legal object (.o) file that you can conceive of. You should think of C as basically dressed-up assembly language.

In particular, C does not require functions to be declared before they are used. If you call a function without declaring it, the use of the function becomes it's (implicit) declaration. In a simple test I just ran, this is only a warning in the case of built-in library functions like printf (at least in GCC), but for random functions, it will compile just fine.

Of course, when you try to link, and it can't find foo, then you will get an error.

In the case of library functions like printf, some compilers contain built-in declarations for them so they can do some basic type checking, so when the implicit declaration (from the use) doesn't match the built-in declaration, you'll get a warning.

If you don't understand Windows Installer then I highly recommend The Definitive Guide to Windows Installer. You can't really use WiX without understanding MSI. Also worth downloading is the Windows Installer 4.5 SDK.

If you don't want to learn the Windows Installer fundamentals, then you'll need some wizard type package to hide all the nitty gritty details and hold your hand. There are plenty of options, some more expensive than others.

• InstallShield
• Advanced Installer
• MSI Factory
• etc..

However still I'd suggest picking up the above book and taking some time to understand what's going on "under the hood", it'll really help you figure out what's going wrong when customers start complaining that something is broken with the setup :)

It is CMD + P (or CTRL + P) by default. However the keyboard bindings may differ according to your preferences.

The easiest way to open an admin Powershell window in Windows 10 (and Windows 8) is to add a "Windows Powershell (Admin)" option to the "Power User Menu". Once this is done, you can open an admin powershell window via Win+X,A or by right-clicking on the start button and selecting "Windows Powershell (Admin)":

Here's where you replace the "Command Prompt" option with a "Windows Powershell" option:

Anybody facing the same issues, follow the simple steps:

Import the project android from downloaded zxing-master zip file using option Import project (Eclipse ADT, Gradle, etc.) and add the dollowing 2 lines of codes in your app level build.gradle file and and you are ready to run.

So simple, yahh...

        // https://mvnrepository.com/artifact/com.google.zxing/core
        compile group: 'com.google.zxing', name: 'core', version: '3.2.1'
        // https://mvnrepository.com/artifact/com.google.zxing/android-core
        compile group: 'com.google.zxing', name: 'android-core', version: '3.2.0'

    }

You can always find latest version core and android core from below links:

You can find accurate answer for this query in oracle documentation page about multiple inheritance

1. Multiple inheritance of state: Ability to inherit fields from multiple classes

   One reason why the Java programming language does not permit you to extend more than one class is to avoid the issues of multiple inheritance of state, which is the ability to inherit fields from multiple classes

   If multiple inheritance is allowed and When you create an object by instantiating that class, that object will inherit fields from all of the class's superclasses. It will cause two issues.

   1. What if methods or constructors from different super classes instantiate the same field?
   2. Which method or constructor will take precedence?

2. Multiple inheritance of implementation: Ability to inherit method definitions from multiple classes

   Problems with this approach: name conflicts and ambiguity. If a subclass and superclass contain same method name (and signature), compiler can't determine which version to invoke.

   But java supports this type of multiple inheritance with default methods, which have been introduced since Java 8 release. The Java compiler provides some rules to determine which default method a particular class uses.

   Refer to below SE post for more details on resolving diamond problem:

   What are the differences between abstract classes and interfaces in Java 8?

3. Multiple inheritance of type: Ability of a class to implement more than one interface.

   Since interface does not contain mutable fields, you do not have to worry about problems that result from multiple inheritance of state here.

You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.

In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.

select
    p.product_id,
    p.type_id,
    p.product_name,
    p.type,
    case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
    Product p

    inner join Product_Type pt on
        pt.type_id = p.type_id

    left join Product_ArtistAuthor paa on
        paa.artist_id = p.artist_id
where
    p.product_id = $pid

I used a left join since I don't know the business logic.

Edit To reflect what @Marc said in the comment below.

You can do a loop through all the posted values.

HTML:

<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />
<input type="checkbox" name="check_list[]" value="<?=$rowid?>" />

PHP:

foreach($_POST['check_list'] as $item){
  // query to delete where item = $item
}

Just start your browser with superuser rights, and don't forget to set Java's JRE security to medium.

You can use jsoup to parse any kind of web page. Here you can find the jsoup library and full source code.

Here is an example: http://desicoding.blogspot.com/2011/03/how-to-parse-html-in-java-jsoup.html

To install in Eclipse:

1. Right Click on project
2. BuildPath
3. Add External Archives
4. select the .jar file

You can parse according to tag/parent/child very comfortably

Why not using the !! operator? This operator, placed before the variable, turn it to a boolean (if I've understood well), so !!undefined and !!null (and even !!NaN, which can be quite interesting) will return false.

Here is an exemple:

function foo(bar){
    console.log(!!bar);
}

foo("hey") //=> will log true

foo() //=> will log false

Check the syntax of your connection string in the web.config. It should be something like ConnectionString="Data Source=C:\DataDictionary\NerdDinner.sdf"

Using JODA:

PeriodFormatter periodFormat = new PeriodFormatterBuilder()
  .minimumParsedDigits(2)
  .appendHour() // 2 digits minimum
  .appendSeparator(":")
  .minimumParsedDigits(2)
  .appendMinute() // 2 digits minimum
  .appendSeparator(":")
  .minimumParsedDigits(2)
  .appendSecond()
  .appendSeparator(".")
  .appendMillis3Digit()
  .toFormatter();
Period result = Period.parse(string, periodFormat);
return result.toStandardDuration().getMillis();

I think this would be a better way to do it in Swift:

func filterContentForSearchText(searchText:NSString, scope:NSString)
{
   searchResults = recipes.filter { name.rangeOfString(searchText) != nil  }
}

define margin and padding for the element is facing the problem:

#element_id {margin: 0; padding: 0}  

and see if problem exists. IE renders the page with to more unwanted inheritance. you should stop it from doing so.

It's even simpler than that. Just did this (on Windows, but it should work on other OS):

1. Create newrepo.
2. Move gitrepo1 into newrepo.
3. Move .git from gitrepo1 to newrepo (up one level).
4. Commit changes (fix tracking as required).

Git just sees you added a directory and renamed a bunch of files. No biggie.

If you are using the ThreeTen backport for Android and can't use the newer Date.from(Instant instant) (which requires minimum of API 26) you can use:

ZonedDateTime zdt = ZonedDateTime.now();
Date date = new Date(zdt.toInstant().toEpochMilli());

or:

Date date = DateTimeUtils.toDate(zdt.toInstant());

For Fedora, Ubuntu, Linux, if you're getting example.com Not a Certification authority error when adding the certificate using the gui to add a new root authority. If you want to trust a server self signed certificate, it cannot make mention of an invalid authority... even if that's itself. I've only managed to make it work by trusting my authority and using that authorities key to sign server certificates.

Here's the self signed CA certificate that it accepted. This is the only way that I found works to get around cert_authority_invalid, I tried for hours to get it to accept a self signed end point certificate, no cigar. The UI will accept self signed authorities, as long as it's declared CA:TRUE. After that, all certs signed by that key with the correct DN will be accepted by chrome without needing to add them independently.

openssl req -new -x509 -extensions v3_req -days 8440 -config ca.conf -key rockstor.key -out rockstor.cert

[req]
distinguished_name=dn
req_extensions=v3_req
prompt = no

[v3_req]
basicConstraints=CA:TRUE,pathlen:0

extendedKeyUsage = serverAuth, clientAuth

If that doesn't work:

• chrome://restart to actually restart

• Try to get more details on the error using firefox, it tends to explain errors better... while chrome will say, ERR_CERTIFICATE_INVALID, firefox will throw: MOZILLA_PKIX_ERROR_CA_CERT_USED_AS_END_ENTITY.

• Remember that chrome now requires Subject Alternate Name and nearly ignores CN.

For others:

• certutil -d sql:$HOME/.pki/nssdb -A -t "P,," -n <nickname> -i <my.crt> // For server sertificates

• certutil -d sql:$HOME/.pki/nssdb -A -t "C,," -n <nickname> -i <my.crt> for CA's https://blogs.oracle.com/meena/about-trust-flags-of-certificates-in-nss-database-that-can-be-modified-by-certutil

• For Firefox, the UI adding an exception certificate does work and it will trust it once you do that.

• Perhaps you have funky settings in /etc/pki/tls/openssl.cnf which get merged with your config.

• perhaps you're no adding an extension to the config or command line, such as v3_req

• Note, my method bypasses the need for a CSR by just signing the certificates with the authority key and adding details for the dev servers. CSR's allow more keys for actual security.

• I tried everything, but chrome requires an authority with basicconstraints CA:true set. And server certificates must all be singed by a valid Authority... even if that's just another certificate that the signed themselves with CA:true.

you could do

distinct_column = 'somecol' 

distinct_column_vals = df.select(distinct_column).distinct().collect()
distinct_column_vals = [v[distinct_column] for v in distinct_column_vals]

you can put everything in a block and easily write any code that you wish in that block just exactly the below code :

@{
        bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
        if (isUserConnected)
        { // meaning that the viewing user has not been saved
            <div>
                <div> click to join us </div>
                <a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
            </div>
        }
    }

it helps you to have at first a cleaner code and also you can prevent your page from loading many times different blocks of codes

You can use vh on the min-height property.

min-height: 100vh;

Worst (won't actually work)

Change the access modifier of counter to public volatile

As other people have mentioned, this on its own isn't actually safe at all. The point of volatile is that multiple threads running on multiple CPUs can and will cache data and re-order instructions.

If it is not volatile, and CPU A increments a value, then CPU B may not actually see that incremented value until some time later, which may cause problems.

If it is volatile, this just ensures the two CPUs see the same data at the same time. It doesn't stop them at all from interleaving their reads and write operations which is the problem you are trying to avoid.

Second Best:

lock(this.locker) this.counter++;

This is safe to do (provided you remember to lock everywhere else that you access this.counter). It prevents any other threads from executing any other code which is guarded by locker. Using locks also, prevents the multi-CPU reordering problems as above, which is great.

The problem is, locking is slow, and if you re-use the locker in some other place which is not really related then you can end up blocking your other threads for no reason.

Best

Interlocked.Increment(ref this.counter);

This is safe, as it effectively does the read, increment, and write in 'one hit' which can't be interrupted. Because of this, it won't affect any other code, and you don't need to remember to lock elsewhere either. It's also very fast (as MSDN says, on modern CPUs, this is often literally a single CPU instruction).

I'm not entirely sure however if it gets around other CPUs reordering things, or if you also need to combine volatile with the increment.

InterlockedNotes:

1. INTERLOCKED METHODS ARE CONCURRENTLY SAFE ON ANY NUMBER OF COREs OR CPUs.
2. Interlocked methods apply a full fence around instructions they execute, so reordering does not happen.
3. Interlocked methods do not need or even do not support access to a volatile field, as volatile is placed a half fence around operations on given field and interlocked is using the full fence.

Footnote: What volatile is actually good for.

As volatile doesn't prevent these kinds of multithreading issues, what's it for? A good example is saying you have two threads, one which always writes to a variable (say queueLength), and one which always reads from that same variable.

If queueLength is not volatile, thread A may write five times, but thread B may see those writes as being delayed (or even potentially in the wrong order).

A solution would be to lock, but you could also use volatile in this situation. This would ensure that thread B will always see the most up-to-date thing that thread A has written. Note however that this logic only works if you have writers who never read, and readers who never write, and if the thing you're writing is an atomic value. As soon as you do a single read-modify-write, you need to go to Interlocked operations or use a Lock.

We should use the transform function from STL algorithm, the last parameter of transform function could be a function object, function pointer or a lambda function that convert item of map to item of vector. This case map have items have type pair that need to convert to item that has int type for vector. Here is my solution that I use lambda function:

#include <algorithm> // for std::transform
#include <iterator>  // for back_inserted

// Map of pair <int, string> need to convert to vector of string
std::map<int, std::string> mapExp = { {1, "first"}, {2, "second"}, {3, "third"}, {4,"fourth"} };

// vector of string to store the value type of map
std::vector<std::string> vValue;

// Convert function
std::transform(mapExp.begin(), mapExp.end(), std::back_inserter(vValue),
       [](const std::pair<int, string> &mapItem)
       {
         return mapItem.second;
       });

If the array is randomly filled, then at the best you can do a linear search in O(n) complexity. However, we could have improved the complexity to O(log n) by divide and conquer approach similar to quick sort as pointed by giri given that the numbers were in ascending/descending order.

The link below will demonstrate how I accomplished this. Not very hard - just have to use some clever front-end dev!!

You can access the USB drive by its drive letter. To know the drive letter you can run this command:

C:\>wmic logicaldisk where drivetype=2 get deviceid, volumename, description

From here you will get the drive letter (Device ID) of your USB drive.

For example if its F: then run the following command in command prompt to see its contents:

C:\> F:

Track the remote branch

You can specify the default remote repository for pushing and pulling using git-branch’s track option. You’d normally do this by specifying the --track option when creating your local master branch, but as it already exists we’ll just update the config manually like so:

Edit your .git/config

[branch "master"]
  remote = origin
  merge = refs/heads/master

Now you can simply git push and git pull.

I suspect you are having a problem with factors. For example,

> x = factor(4:8)
> x
[1] 4 5 6 7 8
Levels: 4 5 6 7 8
> as.numeric(x)
[1] 1 2 3 4 5
> as.numeric(as.character(x))
[1] 4 5 6 7 8

Some comments:

• You mention that your vector contains the characters "Down" and "NoData". What do expect/want as.numeric to do with these values?
• In read.csv, try using the argument stringsAsFactors=FALSE
• Are you sure it's sep="/t and not sep="\t"
• Use the command head(pitchman) to check the first fews rows of your data
• Also, it's very tricky to guess what your problem is when you don't provide data. A minimal working example is always preferable. For example, I can't run the command pichman <- read.csv(file="picman.txt", header=TRUE, sep="/t") since I don't have access to the data set.

Here's the piece of code that saves plot to the selected directory. If the directory does not exist, it is created.

import os

sample_file_name = "sample"

if not os.path.isdir(results_dir):
    os.makedirs(results_dir)

plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.savefig(results_dir + sample_file_name)

I presume you mean curve-fitting and not anti-aliasing from the context of your question. PyPlot doesn't have any built-in support for this, but you can easily implement some basic curve-fitting yourself, like the code seen here, or if you're using GuiQwt it has a curve fitting module. (You could probably also steal the code from SciPy to do this as well).

function showViewPortSize(display) {
    if (display) {
        var height = window.innerHeight;

I suppose that

std::to_string(i)

could do the job, it's an overloaded function, it could be any numeric type such as int, double or float

@MaxPython The answer above is missing ":"

try:
   #do something
except:
  # print 'error/exception'

def printError(e): print e

The easy way, if you have a fixed width and height:

#divElement{
    position: absolute;
    top: 50%;
    left: 50%;
    margin-top: -50px;
    margin-left: -50px;
    width: 100px;
    height: 100px;
}?

Please don't use inline styles! Here is a working example http://jsfiddle.net/S5bKq/.

Try putting this HTML snippet into your served document:

<img id="ItemPreview" src="">

Then, on JavaScript side, you can dynamically modify image's src attribute with so-called Data URL.

document.getElementById("ItemPreview").src = "data:image/png;base64," + yourByteArrayAsBase64;

Alternatively, using jQuery:

$('#ItemPreview').attr('src', `data:image/png;base64,${yourByteArrayAsBase64}`);

This assumes that your image is stored in PNG format, which is quite popular. If you use some other image format (e.g. JPEG), modify the MIME type ("image/..." part) in the URL accordingly.

I had the same problem and after hours of looking found the answer.

The error I was getting was a little different: <path> already exists and is not a valid git repo (and added here for SEO value)

The solution is to NOT create the directory that will house the submodule. The directory will be created as part of the git submodule add command.

Also, the argument is expected to be relative to the parent-repo root, not your working directory, so watch out for that.

Solution for the example above:

1. It IS okay to have your parent repo already cloned.
2. Make sure the common_code directory does not exist.
3. cd Repo
4. git submodule add git://url_to_repo projectfolder/common_code/ (Note the required trailing slash.)
5. Sanity restored.

I hope this helps someone, as there is very little information to be found elsewhere about this.

"Equivalent" is the word here

While...

$('#selectlist').val();

...is equivalent to...

document.getElementById("selectlist").value

...it's worth noting that...

$('#selectlist')

...although 'equivalent' is not the same as...

document.getElementById("selectlist")

...as the former returns a jQuery object, not a DOM object.

To get the DOM object(s) from the jQuery one, use the following:

$('#selectlist').get(); //get all DOM objects in the jQuery collection
$('#selectlist').get(0); //get the DOM object in the jQuery collection at index 0
$('#selectlist')[0]; //get the DOM objects in the jQuery collection at index 0

You don't set the behavior of controls via CSS, only their styling.You can use jquery or simple javascript to change the property of the fields.

Classes are not meant to be just collections of methods. A class is supposed to represent an abstract concept, with both state (fields) and behaviour (methods) which changes the state. Using inheritance just to get some desired behaviour sounds like bad OO design, and exactly the reason why many languages disallow multiple inheritance: in order to prevent "spaghetti inheritance", i.e. extending 3 classes because each has a method you need, and ending up with a class that inherits 100 method and 20 fields, yet only ever uses 5 of them.

Just use

<a href="javascript:;" class="someclass">Text</a>

JQUERY

$('.someclass').click(function(e) { alert("action here"); }

I've always wondered how costly it is to always assume that invoke is required...

private void OnCoolEvent(CoolObjectEventArgs e)
{
  BeginInvoke((o,e) => /*do work here*/,this, e);
}

If you got here to use this in cmd.exe (in a batch file):

powershell -Command (Get-Date).ToString('yyyy-MM-dd')

This has worked for me in the past and it will even expand environment variables in the file if it can.

for /F "delims=" %%a in (LogName.txt) do (
     echo %%a>>MyDestination.txt
)

Try to run the server at a different port. Worked for me:

python manage.py runserver 127.0.0.1:7000

Explanation:

as mentioned on Django documentation:

If you run this script as a user with normal privileges (recommended), you might not have access to start a port on a low port number. Low port numbers are reserved for the superuser (root).

This server uses the WSGI application object specified by the WSGI_APPLICATION setting.

DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that’s how it’s gonna stay. We’re in the business of making Web frameworks, not Web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)

As I am reluctant to install new programs into my machine, this PowerShell script (from Hey, Scripting Guy! Blog) helped me solve my problem. I only modified the path to suit my case:

$fso = Get-ChildItem -Recurse -path F:\songs
$fsoBU = Get-ChildItem -Recurse -path D:\songs
Compare-Object -ReferenceObject $fso -DifferenceObject $fsoBU

Set the PATH as below:

In the csh shell - type setenv PATH "$PATH:/usr/local/bin/python" and press Enter.

In the bash shell (Linux) - type export PATH="$PATH:/usr/local/bin/python" and press Enter.

In the sh or ksh shell - type PATH="$PATH:/usr/local/bin/python" and press Enter.

Note - /usr/local/bin/python is the path of the Python directory

now run as below:

-bash-4.2$ python test.py

Hello, Python!

java.time

It’s about time someone provides the modern answer. The modern solution uses java.time, the modern Java date and time API. The classes SimpleDateFormat and Date used in the question and in a couple of the other answers are poorly designed and long outdated, the former in particular notoriously troublesome. TimeZone is poorly designed to. I recommend you avoid those.

    ZoneId utc = ZoneId.of("Etc/UTC");
    DateTimeFormatter targetFormatter = DateTimeFormatter.ofPattern(
            "MM/dd/yyyy hh:mm:ss a zzz", Locale.ENGLISH);

    String itsAlarmDttm = "2013-10-22T01:37:56";
    ZonedDateTime utcDateTime = LocalDateTime.parse(itsAlarmDttm)
            .atZone(ZoneId.systemDefault())
            .withZoneSameInstant(utc);
    String formatterUtcDateTime = utcDateTime.format(targetFormatter);
    System.out.println(formatterUtcDateTime);

When running in my time zone, Europe/Copenhagen, the output is:

10/21/2013 11:37:56 PM UTC

I have assumed that the string you got was in the default time zone of your JVM, a fragile assumption since that default setting can be changed at any time from another part of your program or another programming running in the same JVM. If you can, instead specify time zone explicitly, for example ZoneId.of("Europe/Podgorica") or ZoneId.of("Asia/Kolkata").

I am exploiting the fact that you string is in ISO 8601 format, the format the the modern classes parse as their default, that is, without any explicit formatter.

I am using a ZonedDateTime for the result date-time because it allows us to format it with UTC in the formatted string to eliminate any and all doubt. For other purposes one would typically have wanted an OffsetDateTime or an Instant instead.

The command

xcode-select --install

proposes 3 options: Get Xcode; Not Now; Install.

When I choose to get full Xcode the command finished successfully. It took a while, but this way I was able to complete all macports migration instructions.

I made an installation guide for Egit on Eclipse so I thought I would share it.

1. INSTALL EGIT plugin in eclispe which is pretty easy. If EGit is missing in your Eclipse installation, you can install it via the Eclipse Update Manager via: Help ? Install new Software. EGit can be installed from the following URL: http://download.eclipse.org/egit/updates Under Eclipse Git Team Provider, tick ONLY "Eclipse EGit" and then download the plugin.

2. CONNECT TO YOUR LOCAL REPOSITORY. I right clicked on the project, selected "team > share project" and then ticked "use or create repository"

3. GIT IGNORE. Mark the "bin" folder as "ignored by Git", either by right-clicking on it and selecting Team > Ignore or by creating a .gitignore file. My file was generated for me, I just had to make it visible. Here's how in eclipse: In your package explorer, pull down the menu and select "Filters ...". You can adjust what types of files are shown/hidden there.

4. IDENTIFY YOURSELF. Click Preferences > Team > Git > Configuration and make sure your name & email are there so we know which user committed/pushed what.

NOW YOU ARE READY TO ADD/COMMIT/PUSH/PULL files with the plugin!

Try implementing the interface as anonymous.

public class MyClass extends MySuperClass implements MyInterface{

MyInterface myInterface = new MyInterface(){

/* Overrided method from interface */
@override
public void method1(){

}

};

/* Overrided method from superclass*/
@override
public void method1(){

}

}

Is maching set to CASE_INSENSITIVE?

This error shows up when you are treating an array or string as a Hash. In this line myHash.each do |item| you are assigning item to a two-element array [key, value], so item[:symbol] throws an error.

You can get the same error in Asp.net MVC5 if you have a class name and a folder with a matching name Example : If you have class lands where when you want to see view/lands/index.cshtml file, if you also have a folder with name 'lands' you get the error as it first try the lands folder

Another way to check is to inline the function, so that the condition will be checked on every render (every props and state change)

const isDisabled = () => 
  // condition check

This works:

<button
  type="button"
  disabled={this.isDisabled()}
>
  Let Me In
</button>

but this will not work:

<button
   type="button"
   disabled={this.isDisabled}
>
  Let Me In
</button>

I want to expand on my readability comment above.

Again, I completely agree with readability overriding other (performance-insignificant) concerns.

What I would like to point out is the brain interprets "positive" faster than it does "negative". E.g., "stop" vs. "do not go" (a rather lousy example due to the difference in number of words).

So given a choice:

if a == b
    (do this)
else
    (do that)

is preferable to the functionally-equivalent:

if a != b
    (do that)
else
    (do this)

Less readability/understandability leads to more bugs. Perhaps not in initial coding, but the (not as smart as you!) maintenance changes...

In Python 3.x the raw_input() of Python 2.x has been replaced by input() function. However in both the cases you cannot input multi-line strings, for that purpose you would need to get input from the user line by line and then .join() them using \n, or you can also take various lines and concatenate them using + operator separated by \n

To get multi-line input from the user you can go like:

no_of_lines = 5
lines = ""
for i in xrange(no_of_lines):
    lines+=input()+"\n"

print(lines)

Or

lines = []
while True:
    line = input()
    if line:
        lines.append(line)
    else:
        break
text = '\n'.join(lines)

Here is a code that works for me, which is a part from the website above combined with my early trials: http://www.codeproject.com/KB/system/DriveDetector.aspx

This basically makes your form listen to windows messages, filters for usb drives and (cd-dvds), grabs the lparam structure of the message and extracts the drive letter.

protected override void WndProc(ref Message m)
    {

        if (m.Msg == WM_DEVICECHANGE)
        {
            DEV_BROADCAST_VOLUME vol = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure(m.LParam, typeof(DEV_BROADCAST_VOLUME));
            if ((m.WParam.ToInt32() == DBT_DEVICEARRIVAL) &&  (vol.dbcv_devicetype == DBT_DEVTYPVOLUME) )
            {
                MessageBox.Show(DriveMaskToLetter(vol.dbcv_unitmask).ToString());
            }
            if ((m.WParam.ToInt32() == DBT_DEVICEREMOVALCOMPLETE) && (vol.dbcv_devicetype == DBT_DEVTYPVOLUME))
            {
                MessageBox.Show("usb out");
            }
        }
        base.WndProc(ref m);
    }

    [StructLayout(LayoutKind.Sequential)] //Same layout in mem
    public struct DEV_BROADCAST_VOLUME
    {
        public int dbcv_size;
        public int dbcv_devicetype;
        public int dbcv_reserved;
        public int dbcv_unitmask;
    }

    private static char DriveMaskToLetter(int mask)
    {
        char letter;
        string drives = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; //1 = A, 2 = B, 3 = C
        int cnt = 0;
        int pom = mask / 2;
        while (pom != 0)    // while there is any bit set in the mask shift it right        
        {        
            pom = pom / 2;
            cnt++;
        }
        if (cnt < drives.Length)
            letter = drives[cnt];
        else
            letter = '?';
        return letter;
    }

Do not forget to add this:

using System.Runtime.InteropServices;

and the following constants:

    const int WM_DEVICECHANGE = 0x0219; //see msdn site
    const int DBT_DEVICEARRIVAL = 0x8000;
    const int DBT_DEVICEREMOVALCOMPLETE = 0x8004;
    const int DBT_DEVTYPVOLUME = 0x00000002;  

When you want the super class constructor to be called - to initialize the fields within it. Take a look at this article for an understanding of when to use it:

http://download.oracle.com/javase/tutorial/java/IandI/super.html

std::fill(v.begin(), v.end(), 0);

origin/xxx branches are always pointer to a remote. You cannot check them out as they're not pointer to your local repository (you only checkout the commit. That's why you won't see the name written in the command line interface branch marker, only the commit hash).

What you need to do to update the remote is to force push your local changes to master:

git checkout master
git reset --hard e3f1e37
git push --force origin master
# Then to prove it (it won't print any diff)
git diff master..origin/master

Understanding the terms:

This picture should give you the idea about the context in which the words breadth and depth are used.

Depth-First Search:

• Depth-first search algorithm acts as if it wants to get as far away from the starting point as quickly as possible.

• It generally uses a Stack to remember where it should go when it reaches a dead end.

• Rules to follow: Push first vertex A on to the Stack

  1. If possible, visit an adjacent unvisited vertex, mark it as visited, and push it on the stack.
  2. If you can’t follow Rule 1, then, if possible, pop a vertex off the stack.
  3. If you can’t follow Rule 1 or Rule 2, you’re done.

• Java code:

  public void searchDepthFirst() {
      // Begin at vertex 0 (A)
      vertexList[0].wasVisited = true;
      displayVertex(0);
      stack.push(0);
      while (!stack.isEmpty()) {
          int adjacentVertex = getAdjacentUnvisitedVertex(stack.peek());
          // If no such vertex
          if (adjacentVertex == -1) {
              stack.pop();
          } else {
              vertexList[adjacentVertex].wasVisited = true;
              // Do something
              stack.push(adjacentVertex);
          }
      }
      // Stack is empty, so we're done, reset flags
      for (int j = 0; j < nVerts; j++)
          vertexList[j].wasVisited = false;
  }
  

• Applications: Depth-first searches are often used in simulations of games (and game-like situations in the real world). In a typical game you can choose one of several possible actions. Each choice leads to further choices, each of which leads to further choices, and so on into an ever-expanding tree-shaped graph of possibilities.

Breadth-First Search:

• The breadth-first search algorithm likes to stay as close as possible to the starting point.
• This kind of search is generally implemented using a Queue.
• Rules to follow: Make starting Vertex A the current vertex
  1. Visit the next unvisited vertex (if there is one) that’s adjacent to the current vertex, mark it, and insert it into the queue.
  2. If you can’t carry out Rule 1 because there are no more unvisited vertices, remove a vertex from the queue (if possible) and make it the current vertex.
  3. If you can’t carry out Rule 2 because the queue is empty, you’re done.

• Java code:

  public void searchBreadthFirst() {
      vertexList[0].wasVisited = true;
      displayVertex(0);
      queue.insert(0);
      int v2;
      while (!queue.isEmpty()) {
          int v1 = queue.remove();
          // Until it has no unvisited neighbors, get one
          while ((v2 = getAdjUnvisitedVertex(v1)) != -1) {
              vertexList[v2].wasVisited = true;
              // Do something
              queue.insert(v2);
          }
      }
      // Queue is empty, so we're done, reset flags
      for (int j = 0; j < nVerts; j++) 
          vertexList[j].wasVisited = false;
  }
  

• Applications: Breadth-first search first finds all the vertices that are one edge away from the starting point, then all the vertices that are two edges away, and so on. This is useful if you’re trying to find the shortest path from the starting vertex to a given vertex.

Hopefully that should be enough for understanding the Breadth-First and Depth-First searches. For further reading I would recommend the Graphs chapter from an excellent data structures book by Robert Lafore.

You can use the following code inside the style tag:

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
/* IE10+ specific styles go here */  
}

Below is an example that worked for me:

<style type="text/css">

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {  
   /* IE10+ specific styles go here */  
   #flashvideo {
        width:320px;
        height:240;
        margin:-240px 0 0 350px;
        float:left;
    }

    #googleMap {
        width:320px;
        height:240;
        margin:-515px 0 0 350px;
        float:left;
        border-color:#000000;
    }
}

#nav li {
    list-style:none;
    width:240px;
    height:25px;
    }

#nav a {
    display:block;
    text-indent:-5000px;
    height:25px;
    width:240px;
    }
</style>

Please note that since (#nav li) and (#nav a) are outside of the @media screen ..., they are general styles.

Span is an inline element. It has no width or height.

You could turn it into a block-level element, then it will accept your dimension directives.

span.product__specfield_8_arrow
{
    display: inline-block; /* or block */
}

Check Whether multidex enabled or not in your build.gradle(app level) under dependencies.if not place like below

dependecies{
multidexEnabled true
}

Check your gradle.properties(app level).if you see the below code

#org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

remove # before the line ,then it should be like this

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

Put your JAR in app/libs, and in app/build.gradle add in the dependencies section:

compile fileTree(dir: 'libs', include: ['*.jar'])

I can tell you for Windows.

1. Install Java Extension Pack and Code Runner Extension from VS Code Extensions.

2. Edit your java home location in VS Code settings, "java.home": "C:\\Program Files\\Java\\jdk-9.0.4".

3. Check if javac is recognized in VS Code internal terminal. If this check fails, try opening VS Code as administrator.

4. Create a simple Java program in Main.java file as:

public class Main {
    public static void main(String[] args) {
        System.out.println("Hello world");     
    }
}

Note: Do not add package in your main class.

5. Right click anywhere on the java file and select run code.

6. Check the output in the console.

Done, hope this helps.

Here is my Java code for Selenium WebDriver. Write the following method and call it during assertion:

protected boolean isElementPresent(By by){
        try{
            driver.findElement(by);
            return true;
        }
        catch(NoSuchElementException e){
            return false;
        }
    }

There is no need to install virtualenv. Just create a workfolder and open your editor in it. Assuming you are using vscode,

$mkdir Directory && cd Directory
$code .

It is the best way to avoid breaking Ubuntu/linux dependencies by messing around with environments. In case anything goes wrong, you can always delete that folder and begin afresh. Otherwise, messing up with the ubuntu/linux python environments could mess up system apps/OS (including the terminal). Then you can press shift+P and type python:select interpreter. Choose any version above 3. After that you can do

$pip3 -v

It will display the pip version. You can then use it for installations as

$pip3 install Library

Text size 2 will be practically invisible. Try it with 14 at least. BTW, using xml has a lot of advantages and will make your life easier once you need to do anything more complex than 'Hello World'.

In my case, Global Settings matters.
After I changed my global network setting with DHCP Servers on, I could start my genymotion virtual device.

1. cmd+, or File > Settings
2. Network
3. Host only Network
4. select vboxnet0, click driver icon
5. Check DHCP on

I blogged it. http://okjsp.tistory.com/1165644212 (sorry for korean, but you can see it from images)

Remove this line from activity if you have added

 @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);
        // Sync the toggle state after onRestoreInstanceState has occurred.
        mDrawerToggle.syncState();
    }

Then set icon

 getSupportActionBar().setHomeAsUpIndicator(icon);

Use properties file. Here is a good start: http://www.mkyong.com/java/java-properties-file-examples/

Basically just add cache:false; in the ajax where you think the content will change as the progress go on. And the place where the content wont change there u can omit this. In this way u will get the new response every time

Turns out the binding of style to a string doesn't work. The solution would be to bind the background of the style.

 <div class="circle" [style.background]="color">

Imagine you end up with double dashes, and want to replace them with a single character and not doubles of the replace character. You can just use array split and array filter and array join.

var str = "This-is---a--news-----item----";

Then to replace all dashes with single spaces, you could do this:

var newStr = str.split('-').filter(function(item) {
  item = item ? item.replace(/-/g, ''): item
  return item;
}).join(' ');

Now if the string contains double dashes, like '----' then array split will produce an element with 3 dashes in it (because it split on the first dash). So by using this line:

item = item ? item.replace(/-/g, ''): item

The filter method removes those extra dashes so the element will be ignored on the filter iteration. The above line also accounts for if item is already an empty element so it doesn't crash on item.replace.

Then when your string join runs on the filtered elements, you end up with this output:

"This is a news item"

Now if you were using something like knockout.js where you can have computer observables. You could create a computed observable to always calculate "newStr" when "str" changes so you'd always have a version of the string with no dashes even if you change the value of the original input string. Basically they are bound together. I'm sure other JS frameworks can do similar things.

In case you have both python 2 and 3 in your path, you can move up the Python27 folder in your path, so it search and executes python 2 first.

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

In my case,

myButton.setEnabled(false);
myButton.setEnabled(true);

is working fine and it is enabling and disabling the button as it should. But once the button state becomes disabled, it never goes back to the enabled state again, although it's clickable. I tried invalidating and refreshing the drawable state, but no luck.

myButton.invalidate();
myButton.refreshDrawableState();

If you or anyone having a similar issue, what works for me is setting the background drawable again. Works on any API Level.

myButton.setEnabled(true);
myButton.setBackgroundDrawable(activity.getResources().getDrawable(R.drawable.myButtonDrawable));

import json
import urllib

url = 'http://example.com/file.json'
r = urllib.request.urlopen(url)
data = json.loads(r.read().decode(r.info().get_param('charset') or 'utf-8'))
print(data)

urllib, for Python 3.4
HTTPMessage, returned by r.info()

paulsm4's answer is the correct one. If in onBackPressed() you just return, it will disable the back button. However, I think a better approach given your use case is to flip the activity logic, i.e. make your home activity the main one, check if the user is signed in there, if not, start the sign in activity. The reason is that if you override the back button in your main activity, most users will be confused when they press back and your app does nothing.

How wide is the text column?

With a GROUP BY there's not much you can do to avoid a data scan (at least an index scan).

I'd recommend:

1. If possible, changing the schema to remove duplication of text data. This way the count will happen on a narrow foreign key field in the 'many' table.

2. Alternatively, creating a generated column with a HASH of the text, then GROUP BY the hash column. Again, this is to decrease the workload (scan through a narrow column index)

Edit:

Your original question did not quite match your edit. I'm not sure if you're aware that the COUNT, when used with a GROUP BY, will return the count of items per group and not the count of items in the entire table.

I assume you calculated the "depth of 1024" by the recurring lines in the stack trace?

Obviously, the stack trace array length in Throwable seems to be limited to 1024. Try the following program:

public class Test {

    public static void main(String[] args) {

        try {
            System.out.println(fact(1 << 15));
        }
        catch (StackOverflowError e) {
            System.err.println("true recursion level was " + level);
            System.err.println("reported recursion level was " +
                               e.getStackTrace().length);
        }
    }

    private static int level = 0;
    public static long fact(int n) {
        level++;
        return n < 2 ? n : n * fact(n - 1);
    }
}

Every form of the query string retrievable from flask request object as described in O'Reilly Flask Web Devleopment:

From O'Reilly Flask Web Development, and as stated by Manan Gouhari earlier, first you need to import request:

from flask import request

request is an object exposed by Flask as a context variable named (you guessed it) request. As its name suggests, it contains all the information that the client included in the HTTP request. This object has many attributes and methods that you can retrieve and call, respectively.

You have quite a few request attributes which contain the query string from which to choose. Here I will list every attribute that contains in any way the query string, as well as a description from the O'Reilly book of that attribute.

First there is args which is "a dictionary with all the arguments passed in the query string of the URL." So if you want the query string parsed into a dictionary, you'd do something like this:

from flask import request

@app.route('/'):
    queryStringDict = request.args

(As others have pointed out, you can also use .get('<arg_name>') to get a specific value from the dictionary)

Then, there is the form attribute, which does not contain the query string, but which is included in part of another attribute that does include the query string which I will list momentarily. First, though, form is "A dictionary with all the form fields submitted with the request." I say that to say this: there is another dictionary attribute available in the flask request object called values. values is "A dictionary that combines the values in form and args." Retrieving that would look something like this:

from flask import request

@app.route('/'):
    formFieldsAndQueryStringDict = request.values

(Again, use .get('<arg_name>') to get a specific item out of the dictionary)

Another option is query_string which is "The query string portion of the URL, as a raw binary value." Example of that:

from flask import request

@app.route('/'):
    queryStringRaw = request.query_string

Then as an added bonus there is full_path which is "The path and query string portions of the URL." Por ejemplo:

from flask import request

@app.route('/'):
    pathWithQueryString = request.full_path

And finally, url, "The complete URL requested by the client" (which includes the query string):

from flask import request

@app.route('/'):
    pathWithQueryString = request.url

Happy hacking :)

Here's a simple example to add two variables:

var1=4
var2=3
let var3=$var1+$var2
echo $var3

The shortest way is to directly add the below code as additional attributes in the input type that you want to change.

onfocus="if(this.value=='Search')this.value=''" 
onblur="if(this.value=='')this.value='Search'"

Please note: Change the text "Search" to "go" or any other text to suit your requirements.

The most common idiom for creating an array without using the inefficient += is something like this, from the output of a loop:

$array = foreach($i in 1..10) { 
  $i
}
$array

You can also use Object Oriented Programming (OOP) instead of procedural programming:

$fiveDays = new DateInterval('P5D');
$today = new DateTime();
$fiveDaysAgo = $today->sub(fiveDays); // or ->add(fiveDays); to add 5 days

Or with just one line of code:

$fiveDaysAgo = (new DateTime())->sub(new DateInterval('P5D'));

Also you will specify route on action for set route

[HttpGet]
[Route("api/customers/")]
public List<Customer> Get()
{
   //gets all customer logic
}

[HttpGet]
[Route("api/customers/currentMonth")]
public List<Customer> GetCustomerByCurrentMonth()
{
     //gets some customer 
}

[HttpGet]
[Route("api/customers/{id}")]
public Customer GetCustomerById(string id)
{
  //gets a single customer by specified id
}
[HttpGet]
[Route("api/customers/customerByUsername/{username}")]
public Customer GetCustomerByUsername(string username)
{
    //gets customer by its username
}

The default keyword parameter should be given to the Column object.

Example:

Column(u'timestamp', TIMESTAMP(timezone=True), primary_key=False, nullable=False, default=time_now),

The default value can be a callable, which here I defined like the following.

from pytz import timezone
from datetime import datetime

UTC = timezone('UTC')

def time_now():
    return datetime.now(UTC)

copy() only works with files.

Both the DOS copy and Unix cp commands will copy recursively - so the quickest solution is just to shell out and use these. e.g.

`cp -r $src $dest`;

Otherwise you'll need to use the opendir/readdir or scandir to read the contents of the directory, iterate through the results and if is_dir returns true for each one, recurse into it.

e.g.

function xcopy($src, $dest) {
    foreach (scandir($src) as $file) {
        if (!is_readable($src . '/' . $file)) continue;
        if (is_dir($src .'/' . $file) && ($file != '.') && ($file != '..') ) {
            mkdir($dest . '/' . $file);
            xcopy($src . '/' . $file, $dest . '/' . $file);
        } else {
            copy($src . '/' . $file, $dest . '/' . $file);
        }
    }
}

I'm afraid Aularon didn't provide enough steps to complete the process. With a little trial and error, I was able to successfully enable Gzipping on my dedicated WHM server.

Below are the steps:

• Run EasyApache within WHM, select Deflate within the Exhaustive Options list, and rebuild the server.

• Once done, goto Services Configuration >> Apache Configuration >> Include Editor >> Post VirtualHost Include, select All Versions, and then paste the mod_headers.c and mod_headers.c code (listed above in Aularon's post) on top of on another within the input field.

• Once saved, I was seeing a 75.36% data savings on average! You can run a before and after test by using this HTTP Compression tool to see your own results: http://www.whatsmyip.org/http_compression/

Hope this works for you all!

setAdapter(null);

Useful if RecycleView have different views type

AFAIK, no, you can't. You have to remove it and recreate it. Actually, you can overwrite a symlink and thus update the pathname referenced by it:

$ ln -s .bashrc test
$ ls -al test
lrwxrwxrwx 1 pascal pascal 7 2009-09-23 17:12 test -> .bashrc
$ ln -s .profile test
ln: creating symbolic link `test': File exists
$ ln -s -f .profile test
$ ls -al test
lrwxrwxrwx 1 pascal pascal 8 2009-09-23 17:12 test -> .profile

EDIT: As the OP pointed out in a comment, using the --force option will make ln perform a system call to unlink() before symlink(). Below, the output of strace on my linux box proving it:

$ strace -o /tmp/output.txt ln -s -f .bash_aliases test
$ grep -C3 ^unlink /tmp/output.txt 
lstat64("test", {st_mode=S_IFLNK|0777, st_size=7, ...}) = 0
stat64(".bash_aliases", {st_mode=S_IFREG|0644, st_size=2043, ...}) = 0
symlink(".bash_aliases", "test")        = -1 EEXIST (File exists)
unlink("test")                          = 0
symlink(".bash_aliases", "test")        = 0
close(0)                                = 0
close(1)                                = 0

So I guess the final answer is "no".

EDIT: The following is copied from Arto Bendiken's answer over on unix.stackexchange.com, circa 2016.

This can indeed be done atomically with rename(2), by first creating the new symlink under a temporary name and then cleanly overwriting the old symlink in one go. As the man page states:

If newpath refers to a symbolic link the link will be overwritten.

In the shell, you would do this with mv -T as follows:

$ mkdir a b
$ ln -s a z
$ ln -s b z.new
$ mv -T z.new z

You can strace that last command to make sure it is indeed using rename(2) under the hood:

$ strace mv -T z.new z
lstat64("z.new", {st_mode=S_IFLNK|0777, st_size=1, ...}) = 0
lstat64("z", {st_mode=S_IFLNK|0777, st_size=1, ...}) = 0
rename("z.new", "z")                    = 0

Note that in the above, both mv -T and strace are Linux-specific.

On FreeBSD, use mv -h alternately.

Editor's note: This is how Capistrano has done it for years now, ever since ~2.15. See this pull request.

JSONArray jsonArray = new JSONArray(yourJsonString);

for (int i = 0; i < jsonArray.length(); i++) {
     JSONObject obj1 = jsonArray.getJSONObject(i);
     JSONArray results = patient.getJSONArray("results");
     String indexForPhone =  patientProfile.getJSONObject(0).getString("indexForPhone"));
}

Change to JSONArray, then convert to JSONObject.

Update MVC 5.1 now supports the below approach directly, so it works for built in editor too. http://www.asp.net/mvc/overview/releases/mvc51-release-notes#new-features (It's either a case of Great mind thinking alike or they read my answer :)

End Update

If your using your own editor template or with MVC 5.1 which now supports the below approach directly for built in editors.

@Html.EditorFor(modelItem => item.YourProperty, 
  new { htmlAttributes = new { @class="verificationStatusSelect", style = "Width:50px"  } })

then in your template (not required for simple types in MVC 5.1)

@Html.TextBoxFor(m => m, ViewData["htmlAttributes"])

The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well. Launching a portrait-only modal from a landscape tab bar controller failed. If you need to do this, then use the trick of displaying and hiding a non-animated modal view, but do it in the viewDidAppear method. It didn't work for me in viewDidLoad or viewWillAppear.

Apart from that, the solutions above work fine.

It's very easy, just run the following JPQL query:

int count = (
(Number)
    entityManager
    .createQuery(
        "select count(b) " +
        "from Book b")
    .getSingleResult()
).intValue();

The reason we are casting to Number is that some databases will return Long while others will return BigInteger, so for portability sake you are better off casting to a Number and getting an int or a long, depending on how many rows you are expecting to be counted.

Let see mounted() I think it is help

https://vuejs.org/v2/api/#mounted

I have a struct KeyValuePairSerializable:

[Serializable]
public struct KeyValuePairSerializable<K, V>
{
    public KeyValuePairSerializable(KeyValuePair<K, V> pair)
    {
        Key = pair.Key;
        Value = pair.Value;
    }

    [XmlAttribute]
    public K Key { get; set; }

    [XmlText]
    public V Value { get; set; }

    public override string ToString()
    {
        return "[" + StringHelper.ToString(Key, "") + ", " + StringHelper.ToString(Value, "") + "]";
    }
}

Then, the XML serialization of a Dictionary property is by:

[XmlIgnore]
public Dictionary<string, string> Parameters { get; set; }

[XmlArray("Parameters")]
[XmlArrayItem("Pair")]
[DebuggerBrowsable(DebuggerBrowsableState.Never)] // not necessary
public KeyValuePairSerializable<string, string>[] ParametersXml
{
    get 
    { 
        return Parameters?.Select(p => new KeyValuePairSerializable<string, string>(p)).ToArray(); 
    }
    set
    {
        Parameters = value?.ToDictionary(i => i.Key, i => i.Value);
    }
}

Just the property must be the array, not the List.

So I figured $0.__vue__ doesn't work very well with HOCs (high order components).

// ListItem.vue
<template>
    <vm-product-item/>
<template>

From the template above, if you have ListItem component, that has ProductItem as it's root, and you try $0.__vue__ in console the result unexpectedly would be the ListItem instance.

Here I got a solution to select the lowest level component (ProductItem in this case).

Plugin

// DomNodeToComponent.js
export default {
  install: (Vue, options) => {
    Vue.mixin({
      mounted () {
        this.$el.__vueComponent__ = this
      },
    })
  },
}

Install

import DomNodeToComponent from'./plugins/DomNodeToComponent/DomNodeToComponent'
Vue.use(DomNodeToComponent)

Use

• In browser console click on dom element.
• Type $0.__vueComponent__.
• Do whatever you want with component. Access data. Do changes. Run exposed methods from e2e.

Bonus feature

If you want more, you can just use $0.__vue__.$parent. Meaning if 3 components share the same dom node, you'll have to write $0.__vue__.$parent.$parent to get the main component. This approach is less laconic, but gives better control.

In your connection string replace server=localhost with "server = Paul-PC\\SQLEXPRESS;"

I'd like to delete not only the word before cursor, but the word after or around cursor as well.

In that case the solution proposed by OP (i.e. using <c-w>) can be combined with the accepted answer to give:

inoremap <c-d> <c-o>daw<c-w>

alternatively (shorter solution):

inoremap <c-d> <c-o>vawobd

Sample input:

word1 word2 word3 word4
               ^------------- Cursor location

Output:

word1 word4

Any definition is valid. As long as you are consistent in your implementation (always put equal nodes to the right, always put them to the left, or never allow them) then you're fine. I think it is most common to not allow them, but it is still a BST if they are allowed and place either left or right.

Use which(mydata_2$height_chad1 == 2585)

Short example

df <- data.frame(x = c(1,1,2,3,4,5,6,3),
                 y = c(5,4,6,7,8,3,2,4))
df
  x y
1 1 5
2 1 4
3 2 6
4 3 7
5 4 8
6 5 3
7 6 2
8 3 4

which(df$x == 3)
[1] 4 8

length(which(df$x == 3))
[1] 2

count(df, vars = "x")
  x freq
1 1    2
2 2    1
3 3    2
4 4    1
5 5    1
6 6    1

df[which(df$x == 3),]
  x y
4 3 7
8 3 4

As Matt Weller pointed out, you can use the length function. The count function in plyr can be used to return the count of each unique column value.

for my case i used the following codes :

    if (!(/\.(gif|jpg|jpeg|tiff|png)$/i).test(fileName)) {              
    alert('You must select an image file only');               
    }

for entry in "$search_dir"/* "$work_dir"/*
do
  if [ -f "$entry" ];then
    echo "$entry"
  fi
done

You can just use sum(people$Weight).

sum sums up a vector, and people$Weight retrieves the weight column from your data frame.

Note - you can get built-in help by using ?sum, ?colSums, etc. (by the way, colSums will give you the sum for each column).

When I ran mongod.exe from Windows Terminal I got a message Unrecognized option: mp. There was an empty mp: in the end of mongod.cfg. Removing that solved the problem for me.

//You can use this ...

Step 1. The first step is to make sure that you declare support for the UITextViewDelegate protocol. This is done in your header file, as example here is the header called

EditorController.h:

@interface EditorController : UIViewController  {
  UITextView *messageTextView;
}

@property (nonatomic, retain) UITextView *messageTextView;

@end

Step 2. Next you will need to register the controller as the UITextView’s delegate. Continuing from the example above, here is how I have initialize the UITextView with EditorController as the delegate …

- (id) init {
    if (self = [super init]) {
        // define the area and location for the UITextView
        CGRect tfFrame = CGRectMake(10, 10, 300, 100);
        messageTextView = [[UITextView alloc] initWithFrame:tfFrame];
        // make sure that it is editable
        messageTextView.editable = YES;

        // add the controller as the delegate
        messageTextView.delegate = self;
    }

Step 3. And now the final piece of the puzzle is to take action in response to the shouldCahngeTextInRange message as follows:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range 
  replacementText:(NSString *)text
{
    // Any new character added is passed in as the "text" parameter
    if ([text isEqualToString:@"\n"]) {
        // Be sure to test for equality using the "isEqualToString" message
        [textView resignFirstResponder];

        // Return FALSE so that the final '\n' character doesn't get added
        return FALSE;
    }
    // For any other character return TRUE so that the text gets added to the view
    return TRUE;
}

Try restarting the application (creating an app_offline.htm than deleting it will do) and if you still get the same error message, make sure you've only declared customErrors once in the web.config, or anything like that. Errors in the web.config can have some weird impact on the application.

this is my solution

JTextField username = new JTextField();
JTextField password = new JPasswordField();
Object[] message = {
    "Username:", username,
    "Password:", password
};

int option = JOptionPane.showConfirmDialog(null, message, "Login", JOptionPane.OK_CANCEL_OPTION);
if (option == JOptionPane.OK_OPTION) {
    if (username.getText().equals("h") && password.getText().equals("h")) {
        System.out.println("Login successful");
    } else {
        System.out.println("login failed");
    }
} else {
    System.out.println("Login canceled");
}

I had the same error. The solution for me was change the ANDROID_HOME path. First I took a look into tools->android->sdk manager from Android Studio. In that window, we can see the path where Android Studio looks for the SDK: image

Then I opened a Windows CMD shell, executed:

echo %ANDROID_HOME%

but the path was different to the one in ANDROID STUDIO CONFIGURATION of the first step.

The solution was to change in user environment, the ANDROID_HOME, to the one of the first step: image

I finally closed the cmd shell, and opened another cmd shell to execute:

echo %ANDROID_HOME%

the path was updated, and I could run my emulator perfectly.

I think this way is better

const index = projects.findIndex(project => project.value==='jquery-ui');
projects[index].desc = "updated desc";

Search till the seconds for the timestamp column in postgress

select * from "TableName" e
    where timestamp >= '2020-08-08T13:00:00' and timestamp < '2020-08-08T17:00:00';

This works:

''.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

It will produce:

'abcdgxre'

You can also use a delimiter like a comma to produce:

'a,b,c,d,g,x,r,e'

By using:

','.join(('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e'))

You could use this one if you mean the jQuery UI css:

<link rel="stylesheet" type="text/css" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />

You are using RxJS 6. Just replace

import { Observable } from 'rxjs/Observable';
import { of } from 'rxjs/observable/of';

by

import { Observable, of } from 'rxjs';

For Bootstrap v4 check this:

https://v4-alpha.getbootstrap.com/components/pagination/#alignment

only add class to ul.pagination:

<nav">
  <ul class="pagination justify-content-center">
    <li class="page-item disabled">
      <a class="page-link" href="#" tabindex="-1">Previous</a>
    </li>
    <li class="page-item"><a class="page-link" href="#">1</a></li>
    <li class="page-item"><a class="page-link" href="#">2</a></li>
    <li class="page-item"><a class="page-link" href="#">3</a></li>
    <li class="page-item">
      <a class="page-link" href="#">Next</a>
    </li>
  </ul>
</nav>

The steps to get this working are:

Within the API Gateway Console ...

1. go to Resources -> Integration Request
2. click on the plus or edit icon next to templates dropdown (odd I know since the template field is already open and the button here looks greyed out)
3. Explicitly type application/json in the content-type field even though it shows a default (if you don't do this it will not save and will not give you an error message)

4. put this in the input mapping { "name": "$input.params('name')" }

5. click on the check box next to the templates dropdown (I'm assuming this is what finally saves it)

Before User Shift + = or Shift - , you have to first set the key map as mentioned below

foreach (DataGridViewColumn column in dataGridView.Columns)
{
    column.SortMode = DataGridViewColumnSortMode.NotSortable;
}

-u option will display including object files if they are added during compilation.

So, to overcome that additionally you may use like this.

svn status -u | grep -v '\?' 

#nav{
    position: -webkit-sticky; /* Safari */
    position: sticky;
    top: 0;
    margin: 0 auto;
    z-index: 9999;
    background-color: white;
}

slightly off-topic (using the CLI instead of PHP), but still worth knowing: You can set the prompt to display the default database by using any of the following

mysql --prompt='\d> '
export MYSQL_PS1='\d> '

or once inside

prompt \d>\_
\R \d>\_

Simply add this tad to your textarea.

onkeydown="if(event.keyCode == 13) return false;"

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.

You get this error because you let a .NET exception happen on your server side, and you didn't catch and handle it, and didn't convert it to a SOAP fault, either.

Now since the server side "bombed" out, the WCF runtime has "faulted" the channel - e.g. the communication link between the client and the server is unusable - after all, it looks like your server just blew up, so you cannot communicate with it any more.

So what you need to do is:

• always catch and handle your server-side errors - do not let .NET exceptions travel from the server to the client - always wrap those into interoperable SOAP faults. Check out the WCF IErrorHandler interface and implement it on the server side

• if you're about to send a second message onto your channel from the client, make sure the channel is not in the faulted state:

  if(client.InnerChannel.State != System.ServiceModel.CommunicationState.Faulted)
  {
     // call service - everything's fine
  }
  else
  {
     // channel faulted - re-create your client and then try again
  }
  

  If it is, all you can do is dispose of it and re-create the client side proxy again and then try again

I don't know of a way to force Chrome to not clear the Network debugger, but this might accomplish what you're looking for:

1. Open the js console
2. window.addEventListener("beforeunload", function() { debugger; }, false)

This will pause chrome before loading the new page by hitting a breakpoint.

First off, EC2 and Elastic Compute Cloud are the same thing.

Next, AWS encompasses the range of Web Services that includes EC2 and Elastic Beanstalk. It also includes many others such as S3, RDS, DynamoDB, and all the others.

EC2

EC2 is Amazon's service that allows you to create a server (AWS calls these instances) in the AWS cloud. You pay by the hour and only what you use. You can do whatever you want with this instance as well as launch n number of instances.

Elastic Beanstalk

Elastic Beanstalk is one layer of abstraction away from the EC2 layer. Elastic Beanstalk will setup an "environment" for you that can contain a number of EC2 instances, an optional database, as well as a few other AWS components such as a Elastic Load Balancer, Auto-Scaling Group, Security Group. Then Elastic Beanstalk will manage these items for you whenever you want to update your software running in AWS. Elastic Beanstalk doesn't add any cost on top of these resources that it creates for you. If you have 10 hours of EC2 usage, then all you pay is 10 compute hours.

Running Wordpress

For running Wordpress, it is whatever you are most comfortable with. You could run it straight on a single EC2 instance, you could use a solution from the AWS Marketplace, or you could use Elastic Beanstalk.

What to pick?

In the case that you want to reduce system operations and just focus on the website, then Elastic Beanstalk would be the best choice for that. Elastic Beanstalk supports a PHP stack (as well as others). You can keep your site in version control and easily deploy to your environment whenever you make changes. It will also setup an Autoscaling group which can spawn up more EC2 instances if traffic is growing.

Here's the first result off of Google when searching for "elastic beanstalk wordpress": https://www.otreva.com/blog/deploying-wordpress-amazon-web-services-aws-ec2-rds-via-elasticbeanstalk/

There's a few:

• Rested
• RESTClient
• REST Easy

I assume you're using RollingFileAppender? In which case, it has a property called MaxBackupIndex which you can set to limit the number of files. For example:

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log
log4j.appender.R.MaxFileSize=100KB
log4j.appender.R.MaxBackupIndex=7
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

You can load HTML page partial, in your case is everything inside div#mytable.

setTimeout(function(){
   $( "#mytable" ).load( "your-current-page.html #mytable" );
}, 2000); //refresh every 2 seconds

more information read this http://api.jquery.com/load/

Update Code (if you don't want it auto-refresh)

<button id="refresh-btn">Refresh Table</button>

<script>
$(document).ready(function() {

   function RefreshTable() {
       $( "#mytable" ).load( "your-current-page.html #mytable" );
   }

   $("#refresh-btn").on("click", RefreshTable);

   // OR CAN THIS WAY
   //
   // $("#refresh-btn").on("click", function() {
   //    $( "#mytable" ).load( "your-current-page.html #mytable" );
   // });


});
</script>

If your merge was not too complicated another option would be to:

1. Move all the changes including the merge changes back to stash using "git stash"
2. Run the merge again and commit your changes (without the changes from the dropped stash)
3. Run a "git stash pop" which should ignore all the changes from your previous merge since the files are identical now.

After that you are left with only the changes from the stash you dropped too early.

Open the file for 'append' rather than 'write'.

with open('file.txt', 'a') as file:
    file.write('input')

Here's the function I use.

function trim(s){ 
  return ( s || '' ).replace( /^\s+|\s+$/g, '' ); 
}

In SSMS there is an easier way with IntelliSense and Aliasing. Try this

1. Right-Click in the text editor and make sure IntelliSense is enabled.
2. Type the query with an alias [SELECT t.* FROM tablename t].
3. Go the text t.* and delete the * ,and SSMS will auto-list the columns of the f aliased table.

In C if you implement count line it will never fail. Yes you can get one extra line if there is stray "ENTER KEY" generally at the end of the file.

File might look some thing like this:

"hello 1
"Hello 2

"

Code below

#include <stdio.h>
#include <stdlib.h>
#define FILE_NAME "file1.txt"

int main() {

    FILE *fd = NULL;
    int cnt, ch;

    fd = fopen(FILE_NAME,"r");
    if (fd == NULL) {
            perror(FILE_NAME);
            exit(-1);
    }

    while(EOF != (ch = fgetc(fd))) {
    /*
     * int fgetc(FILE *) returns unsigned char cast to int
     * Because it has to return EOF or error also.
     */
            if (ch == '\n')
                    ++cnt;
    }

    printf("cnt line in %s is %d\n", FILE_NAME, cnt);

    fclose(fd);
    return 0;
}

Try:

Bitmap yourBitmap;
Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

or:

resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);

I am creating a java method for this purpose with dynamic character

public String insertSpace(String myString,int indexno,char myChar){
    myString=myString.substring(0, indexno)+ myChar+myString.substring(indexno);
    System.out.println(myString);
    return myString;
}

Swift 4,

Another way to achieve this using filter function,

if let object = elements.filter({ $0.title == "title" }).first {
    print("found")
} else {
    print("not found")
}
