Escaping a double quote can absolutely be necessary in sed: for instance, if you are using double quotes in the entire sed expression (as you need to do when you want to use a shell variable).

Here's an example that touches on escaping in sed but also captures some other quoting issues in bash:

# cat inventory
PURCHASED="2014-09-01"
SITE="Atlanta"
LOCATION="Room 154"

Let's say you wanted to change the room using a sed script that you can use over and over, so you variablize the input as follows:

# i="Room 101" (these quotes are there so the variable can contains spaces)

This script will add the whole line if it isn't there, or it will simply replace (using sed) the line that is there with the text plus the value of $i.

if grep -q LOCATION inventory; then 
## The sed expression is double quoted to allow for variable expansion; 
## the literal quotes are both escaped with \ 
    sed -i "/^LOCATION/c\LOCATION=\"$i\"" inventory
## Note the three layers of quotes to get echo to expand the variable
## AND insert the literal quotes
else 
    echo LOCATION='"'$i'"' >> inventory
fi

P.S. I wrote out the script above on multiple lines to make the comments parsable but I use it as a one-liner on the command line that looks like this:

i="your location"; if grep -q LOCATION inventory; then sed -i "/^LOCATION/c\LOCATION=\"$i\"" inventory; else echo LOCATION='"'$i'"' >> inventory; fi

If you're open to out-of-the-DB solution: You could set up a cron job that runs a script that will itself call the procedure.

If you want to start at the "application root" as you describe right click on the top level Default.aspx page and choose set as start page. Hit F5 and you're done.

If you want to start at a different controller action see Mark's answer.

If you choose to throw a NPE and you are using the argument in your method, it might be redundant and expensive to explicitly check for a null. I think the VM already does that for you.

This can easily be done using JavaScript This is applicable to all Browsers

<script type="text/javascript">

/***********************************************
* Disable Text Selection script- © Dynamic Drive DHTML code library (www.dynamicdrive.com)
* This notice MUST stay intact for legal use
* Visit Dynamic Drive at http://www.dynamicdrive.com/ for full source code
***********************************************/

function disableSelection(target){
if (typeof target.onselectstart!="undefined") //For IE 
    target.onselectstart=function(){return false}
else if (typeof target.style.MozUserSelect!="undefined") //For Firefox
    target.style.MozUserSelect="none"
else //All other route (For Opera)
    target.onmousedown=function(){return false}
target.style.cursor = "default"
}
 </script>

Call to this function

<script type="text/javascript">
   disableSelection(document.body)
</script>

C# in .NET 3.5 using System.DirectoryServices.AccountManagement.

 bool valid = false;
 using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
 {
     valid = context.ValidateCredentials( username, password );
 }

This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.

Another solution, using memmove() along with index() and sizeof():

char buf[100] = "abcdef";
char remove = 'b';

char* c;
if ((c = index(buf, remove)) != NULL) {
    size_t len_left = sizeof(buf) - (c+1-buf);
    memmove(c, c+1, len_left);
}

buf[] now contains "acdef"

I use the following method to calculate age:

$oDateNow = new DateTime();
$oDateBirth = new DateTime($sDateBirth);

// New interval
$oDateIntervall = $oDateNow->diff($oDateBirth);

// Output
echo $oDateIntervall->y;

To give a little more flexibility I would add the next function to my repository:

public function findByNot($field, $value)
{
    $qb = $this->createQueryBuilder('a');
    $qb->where($qb->expr()->not($qb->expr()->eq('a.'.$field, '?1')));
    $qb->setParameter(1, $value);

    return $qb->getQuery()
        ->getResult();
}

Then, I could call it in my controller like this:

$this->getDoctrine()->getRepository('MyBundle:Image')->findByNot('id', 1);

Here you've got a very detailed explanation of their differences

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

Update My original answer below was written 6 years ago in a style befitting the times and my understanding. In response to some conversation in the comments, a more modern approach to this is as follows:

    (function() {
        if ( typeof Object.id == "undefined" ) {
            var id = 0;

            Object.id = function(o) {
                if ( typeof o.__uniqueid == "undefined" ) {
                    Object.defineProperty(o, "__uniqueid", {
                        value: ++id,
                        enumerable: false,
                        // This could go either way, depending on your 
                        // interpretation of what an "id" is
                        writable: false
                    });
                }

                return o.__uniqueid;
            };
        }
    })();
    
    var obj = { a: 1, b: 1 };
    
    console.log(Object.id(obj));
    console.log(Object.id([]));
    console.log(Object.id({}));
    console.log(Object.id(/./));
    console.log(Object.id(function() {}));

    for (var k in obj) {
        if (obj.hasOwnProperty(k)) {
            console.log(k);
        }
    }
    // Logged keys are `a` and `b`

If you have archaic browser requirements, check here for browser compatibility for Object.defineProperty.

The original answer is kept below (instead of just in the change history) because I think the comparison is valuable.

You can give the following a spin. This also gives you the option to explicitly set an object's ID in its constructor or elsewhere.

    (function() {
        if ( typeof Object.prototype.uniqueId == "undefined" ) {
            var id = 0;
            Object.prototype.uniqueId = function() {
                if ( typeof this.__uniqueid == "undefined" ) {
                    this.__uniqueid = ++id;
                }
                return this.__uniqueid;
            };
        }
    })();
    
    var obj1 = {};
    var obj2 = new Object();
    
    console.log(obj1.uniqueId());
    console.log(obj2.uniqueId());
    console.log([].uniqueId());
    console.log({}.uniqueId());
    console.log(/./.uniqueId());
    console.log((function() {}).uniqueId());

Take care to make sure that whatever member you use to internally store the unique ID doesn't collide with another automatically created member name.

There is a workaround using vw. Is useful when you can't create a new fluid container. This, inside a classic 'container' div will be full size.

.row-full{
 width: 100vw;
 position: relative;
 margin-left: -50vw;
 left: 50%;
}

After this there is the sidebar problem (thanks to @Typhlosaurus), solved with this js function, calling it on document load and resize:

function full_row_resize(){
    var body_width = $('body').width();
    $('.row-full').css('width', (body_width));
    $('.row-full').css('margin-left', ('-'+(body_width/2)+'px'));
    return false;
}

$adsi = [ADSI]"WinNT://$env:COMPUTERNAME"
$adsi.Children | where {$_.SchemaClassName -eq 'user'} | Foreach-Object {
    $groups = $_.Groups() | Foreach-Object {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)}
    $_ | Select-Object @{n='UserName';e={$_.Name}},@{n='Groups';e={$groups -join ';'}}
}

Simple and effective alternative:

public class ClassName
{
    public List<dynamic> MyProperty { get; set; }
}

or

public class ClassName
{
    public List<object> MyProperty { get; set; }
}

There are two ways to exit a method early (without quitting the program):

• Use the return keyword.
• Throw an exception.

Exceptions should only be used for exceptional circumstances - when the method cannot continue and it cannot return a reasonable value that would make sense to the caller. Usually though you should just return when you are done.

If your method returns void then you can write return without a value:

return;

Specifically about your code:

• There is no need to write the same test three times. All those conditions are equivalent.

• You should also use curly braces when you write an if statement so that it is clear which statements are inside the body of the if statement:

  if (textBox1.Text == String.Empty)
  {
      textBox3.Text += "[-] Listbox is Empty!!!!\r\n";
  }
  return; // Are you sure you want the return to be here??
  

• If you are using .NET 4 there is a useful method that depending on your requirements you might want to consider using here: String.IsNullOrWhitespace.

• You might want to use Environment.Newline instead of "\r\n".
• You might want to consider another way to display invalid input other than writing messages to a text box.

Just a quick note/summary for any who came here via Google looking for the answer to the general question asked in the title (as I was). Any of the following should work for getting access to shell variables inside quotes:

echo "$VARIABLE"
echo "${VARIABLE}"

Use of single quotes is the main issue. According to the Bash Reference Manual:

Enclosing characters in single quotes (') preserves the literal value of each character within the quotes. A single quote may not occur between single quotes, even when preceded by a backslash. [...] Enclosing characters in double quotes (") preserves the literal value of all characters within the quotes, with the exception of $, `, \, and, when history expansion is enabled, !. The characters $ and ` retain their special meaning within double quotes (see Shell Expansions). The backslash retains its special meaning only when followed by one of the following characters: $, `, ", \, or newline. Within double quotes, backslashes that are followed by one of these characters are removed. Backslashes preceding characters without a special meaning are left unmodified. A double quote may be quoted within double quotes by preceding it with a backslash. If enabled, history expansion will be performed unless an ! appearing in double quotes is escaped using a backslash. The backslash preceding the ! is not removed. The special parameters * and @ have special meaning when in double quotes (see Shell Parameter Expansion).

In the specific case asked in the question, $COLUMNS is a special variable which has nonstandard properties (see lhunath's answer above).

Probably your item.photo is undefined if you don't have a photo attribute on item in the first place and thus undefined != ''. But if you'd put some code to show how you provide values to item, it would help.

PS: Sorry to post this as an answer (I rather think it's more of a comment), but I don't have enough reputation yet.

Dir.entries(folder)

example:

Dir.entries(".")

As many others have pointed out there is no first value in a dictionary. The sorting in them is arbitrary and you can't count on the sorting being the same every time you access the dictionary. However if you wanted to print the keys there a couple of ways to it:

for key, value in prices.items():
    print(key)

This method uses tuple assignment to access the key and the value. This handy if you need to access both the key and the value for some reason.

for key in prices.keys():
    print(key)

This will only gives access to the keys as the keys() method implies.

Google Apps Script is javascript, you can use all the string methods...

var grade = itemResponse.getResponse();
if(grade.indexOf("9th")>-1){do something }

You can find doc on many sites, this one for example.

C++20 std::format

This is now the cleanest method in my opinion, as it does not pollute std::cout state with std::hex:

main.cpp

#include <format>
#include <string>

int main() {
    std::cout << std::format("{:x} {:#x} {}\n", 16, 17, 18);
}

Expected output:

10 0x11 18

Not yet implemented on GCC 10.0.1, Ubuntu 20.04.

But the awesome library that became C++20 and should be the same worked once installed with:

git clone https://github.com/fmtlib/fmt
cd fmt
git checkout 061e364b25b5e5ca7cf50dd25282892922375ddc
mkdir build
cmake ..
sudo make install

main2.cpp

#include <fmt/core.h>
#include <iostream>

int main() {
    std::cout << fmt::format("{:x} {:#x} {}\n", 16, 17, 18);
}

Compile and run:

g++ -ggdb3 -O0 -std=c++11 -Wall -Wextra -pedantic -o main2.out main2.cpp -lfmt
./main2.out

Documented at:

• https://en.cppreference.com/w/cpp/utility/format/format
• https://en.cppreference.com/w/cpp/utility/format/formatter#Standard_format_specification

More info at: std::string formatting like sprintf

Pre-C++20: cleanly print and restore std::cout to previous state

main.cpp

#include <iostream>
#include <string>

int main() {
    std::ios oldState(nullptr);
    oldState.copyfmt(std::cout);
    std::cout << std::hex;
    std::cout << 16 << std::endl;
    std::cout.copyfmt(oldState);
    std::cout << 17 << std::endl;
}

Compile and run:

g++ -ggdb3 -O0 -std=c++11 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

Output:

10
17

More details: Restore the state of std::cout after manipulating it

Tested on GCC 10.0.1, Ubuntu 20.04.

To represent the fact that the value is not present you have two choices:

1) If the whole char range is meaningful and you cannot reserve any value, then use char* instead of char:

char** c = new char*[N];
c[0] = NULL; // no character
*c[1] = ' '; // ordinary character
*c[2] = 'a'; // ordinary character
*c[3] = '\0' // zero-code character

Then you'll have c[i] == NULL for when character is not present and otherwise *c[i] for ordinary characters.

2) If you don't need some values representable in char then reserve one for indicating that value is not present, for example the '\0' character.

char* c = new char[N];
c[0] = '\0'; // no character
c[1] = ' '; // ordinary character
c[2] = 'a'; // ordinary character

Then you'll have c[i] == '\0' for when character is not present and ordinary characters otherwise.

Use mysqladmin to kill the runaway query:

Run the following commands:

mysqladmin -uusername -ppassword pr

Then note down the process id.

mysqladmin -uusername -ppassword kill pid

The runaway query should no longer be consuming resources.

Since swift 3.0 there is more convenient way: #imageLiterals here is text example. And below animated example from here:

Plotly supports interactive 2D and 3D graphing. Graphs are rendered with D3.js and can be created with a Python API, matplotlib, ggplot for Python, Seaborn, prettyplotlib, and pandas. You can zoom, pan, toggle traces on and off, and see data on the hover. Plots can be embedded in HTML, apps, dashboards, and IPython Notebooks. Below is a temperature graph showing interactivity. See the gallery of IPython Notebooks tutorials for more examples.

The docs provides examples of supported plot types and code snippets.

Specifically to your question, you can also make interactive plots from NetworkX.



For 3D plotting with Python, you can make 3D scatter, line, and surface plots that are similarly interactive. Plots are rendered with WebGL. For example, see a 3D graph of UK Swap rates.

Disclosure: I'm on the Plotly team.

It is not necessary to use System.Drawing to find the image format in a URI. System.Drawing is not available for .NET Core unless you download the System.Drawing.Common NuGet package and therefore I don't see any good cross-platform answers to this question.

Also, my example does not use System.Net.WebClient since Microsoft explicitly discourage the use of System.Net.WebClient.

We don't recommend that you use the WebClient class for new development. Instead, use the System.Net.Http.HttpClient class.

Download an image from a URL and write it to a file (cross platform)*

*Without old System.Net.WebClient and System.Drawing.

This method will asynchronously download an image (or any file as long as the URI has a file extension) using the System.Net.Http.HttpClient and then write it to a file, using the same file extension as the image had in the URI.

Getting the file extension

First part of getting the file extension is removing all the unnecessary parts from the URI.
We use Uri.GetLeftPart() with UriPartial.Path to get everything from the Scheme up to the Path.
In other words, https://www.example.com/image.png?query&with.dots becomes https://www.example.com/image.png.

After that, we use Path.GetExtension() to get only the extension (in my previous example, .png).

var uriWithoutQuery = uri.GetLeftPart(UriPartial.Path);
var fileExtension = Path.GetExtension(uriWithoutQuery);

Downloading the image

From here it should be straight forward. Download the image with HttpClient.GetByteArrayAsync, create the path, ensure the directory exists and then write the bytes to the path with File.WriteAllBytesAsync() (or File.WriteAllBytes if you are on .NET Framework)

private async Task DownloadImageAsync(string directoryPath, string fileName, Uri uri)
{
    using var httpClient = new HttpClient();

    // Get the file extension
    var uriWithoutQuery = uri.GetLeftPart(UriPartial.Path);
    var fileExtension = Path.GetExtension(uriWithoutQuery);

    // Create file path and ensure directory exists
    var path = Path.Combine(directoryPath, $"{fileName}{fileExtension}");
    Directory.CreateDirectory(directoryPath);

    // Download the image and write to the file
    var imageBytes = await _httpClient.GetByteArrayAsync(uri);
    await File.WriteAllBytesAsync(path, imageBytes);
}

Note that you need the following using directives.

using System;
using System.IO;
using System.Threading.Tasks;
using System.Net.Http;

Example usage

var folder = "images";
var fileName = "test";
var url = "https://cdn.discordapp.com/attachments/458291463663386646/592779619212460054/Screenshot_20190624-201411.jpg?query&with.dots";

await DownloadImageAsync(folder, fileName, new Uri(url));

Notes

• It's bad practice to create a new HttpClient for every method call. It is supposed to be reused throughout the application. I wrote a short example of an ImageDownloader(50 lines) with more documentation that correctly reuses the HttpClient and properly disposes of it that you can find here.

Our system admin resolved this issue by unchecking the box globally for our organization. Users did not even need to log off.

It's useful to define a complete .gitignore file for your project. The reward is safe use of the convenient --all or -a flag to commands like add and commit.

Also, consider defining a global ~/.gitignore file for commonly ignored patterns such as *~, which covers temporary files created by Emacs.

Given the following sample

myData <- data.frame(A=rep(1:2, 3), B=rep(1:3, 2), Pulse=20:25)  

then

myData$A <-as.factor(myData$A)
myData$B <-as.factor(myData$B)

or you could select your columns altogether and wrap it up nicely:

# select columns
cols <- c("A", "B")
myData[,cols] <- data.frame(apply(myData[cols], 2, as.factor))

levels(myData$A) <- c("long", "short")
levels(myData$B) <- c("1kg", "2kg", "3kg")

To obtain

> myData
      A   B Pulse
1  long 1kg    20
2 short 2kg    21
3  long 3kg    22
4 short 1kg    23
5  long 2kg    24
6 short 3kg    25

I'm using angular router ^3.4.7 and I'm still having problems with the routerLinkActive directive.

It's not working if you have multiple link with the same url plus it does not seem to refresh all the time.

Inspired by @tomaszbak answer I created a little component to do the job

There's a workaround to achieve it.

1. First, bind your iframe to a target page with relative url. The browsers will treat the site in iframe the same domain with your website.

2. In your web server, using a rewrite module to redirect request from the relative url to absolute url. If you use IIS, I recommend you check on IIRF module.

A minor modification like below worked for me when using it from within perl and system() call:

sftp {user}@{host} <<< $'put {local_file_path} {remote_file_path}'

Wow, I'm 9 years late to this question. Here you go:

Add this code to your onload.

// This prevents the page from scrolling down to where it was previously.
if ('scrollRestoration' in history) {
    history.scrollRestoration = 'manual';
}
// This is needed if the user scrolls down during page load and you want to make sure the page is scrolled to the top once it's fully loaded. This has Cross-browser support.
window.scrollTo(0,0);

history.scrollRestoration Browser support:

Chrome: supported (since 46)

Firefox: supported (since 46)

Edge: supported (since 79)

IE: not supported

Opera: supported (since 33)

Safari: supported

For IE if you want to re-scroll to the top AFTER it autoscrolls down then this worked for me:

var isIE11 = !!window.MSInputMethodContext && !!document.documentMode;
if(isIE11) {
    setTimeout(function(){ window.scrollTo(0, 0); }, 300);  // adjust time according to your page. The better solution would be to possibly tie into some event and trigger once the autoscrolling goes to the top.
} 

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Many programming languages, especially those derived from C, have support for the so-called Switch Fallthrough. I was searching for the best way to do the same in Ruby and thought it might be useful to others:

In C-like languages fallthrough typically looks like this:

switch (expression) {
    case 'a':
    case 'b':
    case 'c':
        // Do something for a, b or c
        break;
    case 'd':
    case 'e':
        // Do something else for d or e
        break;
}

In Ruby, the same can be achieved in the following way:

case expression
when 'a', 'b', 'c'
  # Do something for a, b or c
when 'd', 'e'
  # Do something else for d or e
end

This is not strictly equivalent, because it's not possible to let 'a' execute a block of code before falling through to 'b' or 'c', but for the most part I find it similar enough to be useful in the same way.

As the given tag to this question is CSS, I will provide the way I accomplished it.

1. Create a class in the .css file.

   a.activePage{ color: green; border-bottom: solid; border-width: 3px;}

2. Nav-bar will be like:

   • Home
   • Contact Us
   • About Us

NOTE: If you are already setting the style for all Nav-Bar elements using a class, you can cascade the special-case class we created with a white-space after the generic class in the html-tag.

Example: Here, I was already importing my style from a class called 'navList' I created for all list-items . But the special-case styling-attributes are part of class 'activePage'

.CSS file:

a.navList{text-decoration: none; color: gray;}
a.activePage{ color: green; border-bottom: solid; border-width: 3px;}

.HTML file:

<div id="sub-header">
    <ul>

Look how I've cascaded one class-name behind other.

In C++ using the regex library

The answer would go about like this:

[0-9]?([0-9]*[.])?[0-9]+

Notice that I don't take the sign symbol, if you wanted it with the sign symbol it would go about this:

[+-]?([0-9]*[.])?[0-9]+

This also separates a regular number or a decimal number.

There is a Swift 3 solution from the checked solution :

self.perform(#selector(self.targetMethod), with: self, afterDelay: 1.0)

And there is the method

@objc fileprivate func targetMethod(){

}

Timestamp in saving workbook path, the ":" needs to be changed. I used ":" -> "." which implies that I need to add the extension back "xlsx".

wb(x).SaveAs ThisWorkbook.Path & "\" & unique(x) & " - " & Format(Now(), "mm-dd-yy, hh.mm.ss") & ".xlsx"

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

If you are at a certain branch mybranch, just go ahead and git checkout commit_hash. Then you can return to your branch by git checkout mybranch. I had the same game bisecting a bug today :) Also, you should know about git bisect.

public static String RandomAlphanum(int length)
{
    String charstring = "abcdefghijklmnopqrstuvwxyz0123456789";
    String randalphanum = "";
    double randroll;
    String randchar;
    for (double i = 0; i < length; i++)
    {
        randroll = Math.random();
        randchar = "";
        for (int j = 1; j <= 35; j++)
        {
            if (randroll <= (1.0 / 36.0 * j))
            {
                randchar = Character.toString(charstring.charAt(j - 1));
                break;
            }
        }
        randalphanum += randchar;
    }
    return randalphanum;
}

I used a very primitive algorithm using Math.random(). To increase randomness, you can directly implement the util.Date class. Nevertheless, it works.

I have a maven project with three submodules that is managed in git. I set them up in eclipse as follows:

1. I registered the git repository with eclipse using EGit
2. I imported the projects as existing Maven Projects
3. For each project, I went Team | Share Project.

You should be able to rely on os.name.

import os
if os.name == 'nt':
    # ...

edit: Now I'd say the clearest way to do this is via the platform module, as per the other answer.

you have to used.

String value= et.getText().toString();
int finalValue=Integer.parseInt(value);

if you have only allow enter number then set EditText property.

android:inputType="number"

if this is helpful then accept otherwise put your comment.

For TypeScript users:

    toggle(event: Event): void {
        let elementId: string = (event.target as Element).id;
        // do something with the id... 
    }

Use the parent axes with the parent node's name.

//*[title="50"]/parent::store

This XPath will only select the parent node if it is a store.

But you can also use one of these

//*[title="50"]/parent::*
//*[title="50"]/..

These xpaths will select any parent node. So if the document changes you will always select a node, even if it is not the node you expect.

EDIT

What happens in the given example where the parent is a bicycle but the parent of the parent is a store?

Does it ascent?

No, it only selects the store if it is a parent of the node that matches //*[title="50"].

If not, is there a method to ascent in such cases and return None if there is no such parent?

Yes, you can use ancestor axes

//*[title="50"]/ancestor::store

This will select all ancestors of the node matching //*[title="50"] that are ` stores. E.g.

<data xmlns:d="defiant-namespace" d:mi="23">
    <store mi="1">
        <store mi="22">
            <book price="8.95" d:price="Number" d:mi="13">
                <title d:constr="String" d:mi="10">50</title>
                <category d:constr="String" d:mi="11">reference</category>
                <author d:constr="String" d:mi="12">Nigel Rees</author>
            </book>
        </store>
    </store>
</data>

BE VERY CAREFUL, the problem may come from multibytes encoding and inappropriate PHP functions used...

It was the case for me and it took me a while to figure it out.

For example, I get the a string from MySQL using utf8mb4 (very common now to encode emojis):

$formattedString = strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WILL RETURN THE ERROR 'Detected an illegal character in input string'

The problem does not stand in iconv() but stands in strtolower() in this case.

The appropriate way is to use Multibyte String Functions mb_strtolower() instead of strtolower()

$formattedString = mb_strtolower($stringFromMysql);
$strCleaned = iconv('UTF-8', 'utf-8//TRANSLIT', $formattedString); // WORK FINE

MORE INFO

More examples of this issue are available at this SO answer

PHP Manual on the Multibyte String

Readonly is an attribute as defined in html, so treat it like one.

You need to have something like readonly="readonly" in the object you are working with if you want it not to be editable. And if you want it to be editable again you won't have something like readonly='' (this is not standard if I understood correctly). You really need to remove the attribute as a whole.

As such, while using jquery adding it and removing it is what makes sense.

Set something readonly:

$("#someId").attr('readonly', 'readonly');

Remove readonly:

$("#someId").removeAttr('readonly');

This was the only alternative that really worked for me. Hope it helps!

This exception can also occur when you have a custom view in your layout like this:

<com.example.MyView
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

and you change the view's package name from "com.example" to something different, but you forget to change it in the layout as well.

git stash branch will works, which creates a new branch for you, checks out the commit you were on when you stashed your work, reapplies your work there, and then drops the stash if it applies successfully. check this

Similar to yebmouxing I could not the

 xhr.getResponseHeader('Set-Cookie');

method to work. It would only return null even if I had set HTTPOnly to false on my server.

I too wrote a simple js helper function to grab the cookies from the document. This function is very basic and only works if you know the additional info (lifespan, domain, path, etc. etc.) to add yourself:

function getCookie(cookieName){
  var cookieArray = document.cookie.split(';');
  for(var i=0; i<cookieArray.length; i++){
    var cookie = cookieArray[i];
    while (cookie.charAt(0)==' '){
      cookie = cookie.substring(1);
    }
    cookieHalves = cookie.split('=');
    if(cookieHalves[0]== cookieName){
      return cookieHalves[1];
    }
  }
  return "";
}

I had a similar problem with a small difference: some a.category_id are not in b and some b.category_id are not in a.
To solve this problem just adapt the excelent answer from beny23 to

select a.col1, b.col2, a.col3, b.col4, a.category_id 
from items_a a
LEFT OUTER JOIN
items_b b 
on a.category_id = b.category_id

Hope this helps someone.

Here's a great reason to use objectForKey: wherever possible instead of valueForKey: - valueForKey: with an unknown key will throw NSUnknownKeyException saying "this class is not key value coding-compliant for the key ".

try running after changing file name from '-' to `_'

for eg: .\my_app\my_fle.bat

instead of .\\my-app\my-fle.bat

Or

cd my_app  
 .\my_file.bat

You can use inline styles but you will have some limitations if you are using them in all of your stylings, some known limitations are you can't use CSS pseudo selectors and media queries in there.

You can use Radium to solve this but still, I feel has the project grows its gonna get cumbersome.

I would recommend using CSS modules.

using CSS Modules you will have the freedom of writing CSS in CSS file and don't have to worry about the naming clashes, it will be taken care by CSS Modules.

An advantage of this method is that it gives you styling functionality to the specific component. This will create much more maintainable code and readable project architecture for the next developer to work on your project.

I just wanted to add a solution for Windows machines.

• Windows Server 2008 R2 Standard, SP1
• Jenkins 2.89.4
• Java version 8.171

Symptom: Jenkins service starts and immediately stops.
Jenkins.wrapper.log has a line indicating the incorrect path to Java:

- Starting C:\Program Files\Java\jre1.8.0_141\bin\java -Xrs -Xmx6g -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "C:\Program Files (x86)\Jenkins\jenkins.war" --httpPort=8080 --webroot="C:\Program Files (x86)\Jenkins\war"

The fix: Jenkins has the path hard-coded in jenkins.xml. Change the path to the new Java location.

<env name="JENKINS_HOME" value="%BASE%"/>
<!--
if you'd like to run Jenkins with a specific version of Java, specify a full path to java.exe.
The following value assumes that you have java in your PATH.
-->
<executable>C:\Program Files\Java\jre1.8.0_171\bin\java</executable>
<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war"</arguments>

You can also use Windows Environment Variables, but I wasn't successful with that and I don't think the Java installer updates those, so you'd need to update that by hand every time anyway.

<env name="JENKINS_HOME" value="%BASE%"/>
<!--
if you'd like to run Jenkins with a specific version of Java, specify a full path to java.exe.
The following value assumes that you have java in your PATH.
-->
<executable>%JAVA_HOME%\bin\java</executable>
<arguments>-Xrs -Xmx256m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%\jenkins.war" --httpPort=8080 --webroot="%BASE%\war"</arguments>

min-width and max-width properties do not work the way you expect for table cells. From spec:

In CSS 2.1, the effect of 'min-width' and 'max-width' on tables, inline tables, table cells, table columns, and column groups is undefined.

This hasn't changed in CSS3.

A dozen pages is not a big deal when using OFFSET. But when you have hundreds of pages, you will find that OFFSET is bad for performance. This is because all the skipped rows need to be read each time.

It is better to remember where you left off.

OnCreate:

//Add comment fragment
            container = FindViewById<FrameLayout>(Resource.Id.frmAttachPicture);
            mPictureFragment = new fmtAttachPicture();

            var trans = SupportFragmentManager.BeginTransaction();
            trans.Add(container.Id, mPictureFragment, "fmtPicture");
            trans.Show(mPictureFragment); trans.Commit();

This is how I hide the fragment in click event 1

//Close fragment
    var trans = SupportFragmentManager.BeginTransaction();
    trans.Hide(mPictureFragment);
    trans.AddToBackStack(null);
    trans.Commit();

Then Shows it back int event 2

var trans = SupportFragmentManager.BeginTransaction();
            trans.Show(mPictureFragment); trans.Commit();

In a HashMap the key is an object, that contains hashCode() and equals(Object) methods.

When you insert a new entry into the Map, it checks whether the hashCode is already known. Then, it will iterate through all objects with this hashcode, and test their equality with .equals(). If an equal object is found, the new value replaces the old one. If not, it will create a new entry in the map.

Usually, talking about maps, you use collision when two objects have the same hashCode but they are different. They are internally stored in a list.

This should fix a few edge-cases in kobe's answer:

function getQueryParam(url, key) {
  var queryStartPos = url.indexOf('?');
  if (queryStartPos === -1) {
    return;
  }
  var params = url.substring(queryStartPos + 1).split('&');
  for (var i = 0; i < params.length; i++) {
    var pairs = params[i].split('=');
    if (decodeURIComponent(pairs.shift()) == key) {
      return decodeURIComponent(pairs.join('='));
    }
  }
}

getQueryParam('http://example.com/form_image_edit.php?img_id=33', 'img_id');
// outputs "33"

Figure out what version of python3 you have installed:

yum search pip

and then install the best match. Use reqoquery to find name of resulting pip3.e.g

repoquery -l python36u-pip

tells me to use pip3.6 instead of pip3

Check out this answer to a similar question like this which states that

The u- prefix just means that you have a Unicode string. When you really use the string, it won't appear in your data. Don't be thrown by the printed output.

For example, try this:

print mail_accounts[0]["i"]

You won't see a u.

If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:

Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);

Hope it helps.

The reason for this is that I am printing these out to a document and I want to use the key name and the value in doing this

Based on the above requirement this is what I would suggest:

keys = mydictionary.keys()
keys.sort()

for each in keys:
    print "%s: %s" % (each, mydictionary.get(each))

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark` 
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          AFTER `<TABLE COLUMN BEFORE THIS COLUMN>`";

I believe you need to have ADD COLUMN and use AFTER, not BEFORE.

In case you want to place column at the beginning of a table, use the FIRST statement:

$query = "ALTER TABLE `" . $table_prefix . "posts_to_bookmark`
          ADD COLUMN `ping_status` INT(1) NOT NULL 
          FIRST";

I'd suggest, to add in the nugget package:

  Install-Package OpenDialog

Then the way to used it is:

    Gat.Controls.OpenDialogView openDialog = new Gat.Controls.OpenDialogView();
    Gat.Controls.OpenDialogViewModel vm = (Gat.Controls.OpenDialogViewModel)openDialog.DataContext;
    vm.IsDirectoryChooser = true;
    vm.Show();

    WPFLabel.Text = vm.SelectedFilePath.ToString();

Here's the documentation: http://opendialog.codeplex.com/documentation

Works for Files, files with filter, folders, etc

document.body.style.cursor = 'cursorurl';

You have basically two options:

1. You merge. That is actually quite simple, and a perfectly local operation:

   git checkout b1
   git merge master
   # repeat for b2 and b3
   

   This leaves the history exactly as it happened: You forked from master, you made changes to all branches, and finally you incorporated the changes from master into all three branches.

   git can handle this situation really well, it is designed for merges happening in all directions, at the same time. You can trust it be able to get all threads together correctly. It simply does not care whether branch b1 merges master, or master merges b1, the merge commit looks all the same to git. The only difference is, which branch ends up pointing to this merge commit.

2. You rebase. People with an SVN, or similar background find this more intuitive. The commands are analogue to the merge case:

   git checkout b1
   git rebase master
   # repeat for b2 and b3
   

   People like this approach because it retains a linear history in all branches. However, this linear history is a lie, and you should be aware that it is. Consider this commit graph:

   A --- B --- C --- D <-- master
    \
     \-- E --- F --- G <-- b1
   

   The merge results in the true history:

   A --- B --- C --- D <-- master
    \                 \
     \-- E --- F --- G +-- H <-- b1
   

   The rebase, however, gives you this history:

   A --- B --- C --- D <-- master
                      \
                       \-- E' --- F' --- G' <-- b1
   

   The point is, that the commits E', F', and G' never truly existed, and have likely never been tested. They may not even compile. It is actually quite easy to create nonsensical commits via a rebase, especially when the changes in master are important to the development in b1.

   The consequence of this may be, that you can't distinguish which of the three commits E, F, and G actually introduced a regression, diminishing the value of git bisect.

   I am not saying that you shouldn't use git rebase. It has its uses. But whenever you do use it, you need to be aware of the fact that you are lying about history. And you should at least compile test the new commits.

scope - https://www.googleapis.com/auth/userinfo.profile

return youraccess_token = access_token

get https://www.googleapis.com/oauth2/v1/userinfo?alt=json&access_token=youraccess_token

you will get json:

 "name": "xx",
 "given_name": "xx",
 "family_name": "xx",
 "link": "xx",
 "picture": "xx",
 "gender": "xx",

}

To Tahir Yasin:

This is a php example.
You can use json_decode function to get userInfo array.

$q = 'https://www.googleapis.com/oauth2/v1/userinfo?access_token=xxx';
$json = file_get_contents($q);
$userInfoArray = json_decode($json,true);
$googleEmail = $userInfoArray['email'];
$googleFirstName = $userInfoArray['given_name'];
$googleLastName = $userInfoArray['family_name'];

I think that you should make the reference to your config file

26399:C 16 Jan 08:51:13.413 # Warning: no config file specified, using the default config. In order to specify a config file use ./redis-server /path/to/redis.conf

you can try to start your redis server like

./redis-server /path/to/redis-stable/redis.conf

Sounds like you'd like to use toLocaleString() on your numeric inputs.

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toLocaleString for its usage.

Localization of numbers in JS is also covered in Internationalization(Number formatting "num.toLocaleString()") not working for chrome

You can not alter constraints ever but you can drop them and then recreate.

Have look on this

ALTER TABLE your_table DROP CONSTRAINT ACTIVEPROG_FKEY1;

and then recreate it with ON DELETE CASCADE like this

ALTER TABLE your_table
add CONSTRAINT ACTIVEPROG_FKEY1 FOREIGN KEY(ActiveProgCode) REFERENCES PROGRAM(ActiveProgCode)
    ON DELETE CASCADE;

hope this help

Why setContentView() in Android Had Been So Popular Till Now?

setContentView(int layoutid) - method of activity class. It shows layout on screen.

R.layout.main - is an integer number implemented in nested layout class of R.java class file.

At the run time device will pick up their layout based on the id given in setcontentview() method.

Thank to Brian for the code. I was trying to connect to the sql server with {call spname(?,?)} and I got errors, but when I change my code to exec sp... it works very well.

I post my code in hope this helps others with problems like mine:

try {
    cs=conn.prepareStatement("exec sp_name ?,?,?,?,?,?,?");
    cs.setEscapeProcessing(true);

    cs.setString(1, "valueA");

    cs.setString(2, "valueB");

    cs.setString(3, "0418");

    //commented, because no need to register parameters out!, I got results from the resultset. 
    //cs.registerOutParameter(1, Types.VARCHAR);
    //cs.registerOutParameter(2, Types.VARCHAR);

    rs = cs.executeQuery();
    ArrayList<ObjectX> listaObjectX = new ArrayList<ObjectX>();
    while (rs.next()) {

        ObjectX to = new ObjectX();

You want to be using java.lang.reflect.Constructor.newInstance(Object...)

As far as I know you can only join this way:

var query = from obj_i in set1
join obj_j in set2 on 
    new { 
      JoinProperty1 = obj_i.SomeField1,
      JoinProperty2 = obj_i.SomeField2,
      JoinProperty3 = obj_i.SomeField3,
      JoinProperty4 = obj_i.SomeField4
    } 
    equals 
    new { 
      JoinProperty1 = obj_j.SomeOtherField1,
      JoinProperty2 = obj_j.SomeOtherField2,
      JoinProperty3 = obj_j.SomeOtherField3,
      JoinProperty4 = obj_j.SomeOtherField4
    }

The main requirements are: Property names, types and order in the anonymous objects you're joining on must match.

You CAN'T use ANDs, ORs, etc. in joins. Just object1 equals object2.

More advanced stuff in this LinqPad example:

class c1 
    {
    public int someIntField;
    public string someStringField;
    }
    
class c2 
    {
    public Int64 someInt64Property {get;set;}
    private object someField;
    public string someStringFunction(){return someField.ToString();}
    }
    
void Main()
{
    var set1 = new List<c1>();
    var set2 = new List<c2>();
    
    var query = from obj_i in set1
    join obj_j in set2 on 
        new { 
                JoinProperty1 = (Int64) obj_i.someIntField,
                JoinProperty2 = obj_i.someStringField
            } 
        equals 
        new { 
                JoinProperty1 = obj_j.someInt64Property,
                JoinProperty2 = obj_j.someStringFunction()
            }
    select new {obj1 = obj_i, obj2 = obj_j};
}

Addressing names and property order is straightforward, addressing types can be achieved via casting/converting/parsing/calling methods etc. This might not always work with LINQ to EF or SQL or NHibernate, most method calls definitely won't work and will fail at run-time, so YMMV (Your Mileage May Vary). This is because they are copied to public read-only properties in the anonymous objects, so as long as your expression produces values of correct type the join property - you should be fine.

What it is telling you is - the 2nd guard let or the if let check is not happening on an Optional Int or Optional String. You already have a non-optional value, so guarding or if-letting is not needed anymore

Instead of downloading curl, down libcurl.

curl is just the application, libcurl is what you need for your C++ program

To add/subtract from a DATE, you have 2 options :

Method #1 : The easiest way is to use + and - to add/subtract days, hours, minutes, seconds, etc.. from a DATE, and ADD_MONTHS() function to add/subtract months and years from a DATE. Why ? That's because from days, you can get hours and any smaller unit (1 hour = 1/24 days), (1 minute = 1/1440 days), etc... But you cannot get months and years, as that depends on the month and year themselves, hence ADD_MONTHS() and no add_years(), because from months, you can get years (1 year = 12 months).

Let's try them :

SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS')             FROM dual;        -- prints current date:    19-OCT-2019 20:42:02 
SELECT TO_CHAR((SYSDATE + 1/24), 'DD-MON-YYYY HH24:MI:SS')    FROM dual;        -- prints date + 1 hour:   19-OCT-2019 21:42:02
SELECT TO_CHAR((SYSDATE + 1/1440), 'DD-MON-YYYY HH24:MI:SS')  FROM dual;        -- prints date + 1 minute: 19-OCT-2019 20:43:02 
SELECT TO_CHAR((SYSDATE + 1/86400), 'DD-MON-YYYY HH24:MI:SS') FROM dual;        -- prints date + 1 second: 19-OCT-2019 20:42:03 
-- Same goes for subtraction.

SELECT SYSDATE                  FROM dual;       -- prints current date:     19-OCT-19
SELECT ADD_MONTHS(SYSDATE, 1)   FROM dual;       -- prints date + 1 month:   19-NOV-19
SELECT ADD_MONTHS(SYSDATE, 12)  FROM dual;       -- prints date + 1 year:    19-OCT-20
SELECT ADD_MONTHS(SYSDATE, -3)  FROM dual;       -- prints date - 3 months:  19-JUL-19

Method #2 : Using INTERVALs, you can or subtract an interval (duration) from a date easily. More than that, you can combine to add or subtract multiple units at once (e.g 5 hours and 6 minutes, etc..) Examples :

SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS')                                        FROM dual;        -- prints current date:                 19-OCT-2019 21:34:15
SELECT TO_CHAR((SYSDATE + INTERVAL '1' HOUR), 'DD-MON-YYYY HH24:MI:SS')                  FROM dual;        -- prints date + 1 hour:                19-OCT-2019 22:34:15
SELECT TO_CHAR((SYSDATE + INTERVAL '1' MINUTE), 'DD-MON-YYYY HH24:MI:SS')                FROM dual;        -- prints date + 1 minute:              19-OCT-2019 21:35:15
SELECT TO_CHAR((SYSDATE + INTERVAL '1' SECOND), 'DD-MON-YYYY HH24:MI:SS')                FROM dual;        -- prints date + 1 second:              19-OCT-2019 21:34:16
SELECT TO_CHAR((SYSDATE + INTERVAL '01:05:00' HOUR TO SECOND), 'DD-MON-YYYY HH24:MI:SS') FROM dual;        -- prints date + 1 hour and 5 minutes:  19-OCT-2019 22:39:15
SELECT TO_CHAR((SYSDATE + INTERVAL '3 01' DAY TO HOUR), 'DD-MON-YYYY HH24:MI:SS')        FROM dual;        -- prints date + 3 days and 1 hour:     22-OCT-2019 22:34:15
SELECT TO_CHAR((SYSDATE - INTERVAL '10-3' YEAR TO MONTH), 'DD-MON-YYYY HH24:MI:SS')      FROM dual;        -- prints date - 10 years and 3 months: 19-JUL-2009 21:34:15

Simple use text = text + string2

The example above can be simplify a bit. Additionally you can put date manually from keyboard instead of selecting it via datepicker only. When clearing the value you need to handle also 'on clearDate' action to remove startDate/endDate boundary:

JS file:

$(".from_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var startDate = new Date(selected.date.valueOf());
    $('.to_date').datepicker('setStartDate', startDate);
}).on('clearDate', function (selected) {
    $('.to_date').datepicker('setStartDate', null);
});

$(".to_date").datepicker({
    format: 'yyyy-mm-dd',
    autoclose: true,
}).on('changeDate', function (selected) {
    var endDate = new Date(selected.date.valueOf());
    $('.from_date').datepicker('setEndDate', endDate);
}).on('clearDate', function (selected) {
    $('.from_date').datepicker('setEndDate', null);
});

HTML:

<input class="from_date" placeholder="Select start date" type="text" name="from_date">
<input class="to_date" placeholder="Select end date" type="text" name="to_date">

  import ReactDOM from 'react-dom';
  //...
  componentDidMount() {
    var n = ReactDOM.findDOMNode(this);
    console.log(n.offsetTop);
  }

You can just grab the offsetTop from the Node.

Use Range in Python 3.

Here is a example function that return in between numbers from two numbers

def get_between_numbers(a, b):
    """
    This function will return in between numbers from two numbers.
    :param a:
    :param b:
    :return:
    """
    x = []
    if b < a:
        x.extend(range(b, a))
        x.append(a)
    else:
        x.extend(range(a, b))
        x.append(b)

    return x

Result

print(get_between_numbers(5, 9))
print(get_between_numbers(9, 5))

[5, 6, 7, 8, 9]  
[5, 6, 7, 8, 9]

Try

//*[text()='qwerty'] because . is your current element

Here is the code and demo for Adding the marker, deleting any of the marker and also getting all the present/added markers :

Here is the entire JSFiddle code . Also here is the full page demo.

Adding the marker :

// Script for adding marker on map click
map.on('click', onMapClick);

function onMapClick(e) {

    var geojsonFeature = {

        "type": "Feature",
        "properties": {},
        "geometry": {
                "type": "Point",
                "coordinates": [e.latlng.lat, e.latlng.lng]
        }
    }

    var marker;

    L.geoJson(geojsonFeature, {

        pointToLayer: function(feature, latlng){

            marker = L.marker(e.latlng, {

                title: "Resource Location",
                alt: "Resource Location",
                riseOnHover: true,
                draggable: true,

            }).bindPopup("<input type='button' value='Delete this marker' class='marker-delete-button'/>");

            marker.on("popupopen", onPopupOpen);

            return marker;
        }
    }).addTo(map);
}

Deleting the Marker :

// Function to handle delete as well as other events on marker popup open

function onPopupOpen() {

    var tempMarker = this;

    // To remove marker on click of delete button in the popup of marker
    $(".marker-delete-button:visible").click(function () {
        map.removeLayer(tempMarker);
    });
}

Getting all the markers in the map :

// getting all the markers at once
function getAllMarkers() {

    var allMarkersObjArray = []; // for marker objects
    var allMarkersGeoJsonArray = []; // for readable geoJson markers

    $.each(map._layers, function (ml) {

        if (map._layers[ml].feature) {

            allMarkersObjArray.push(this)
            allMarkersGeoJsonArray.push(JSON.stringify(this.toGeoJSON()))
        }
    })

    console.log(allMarkersObjArray);
}

// any html element such as button, div to call the function()
$(".get-markers").on("click", getAllMarkers);

I could not get this working with the accepted answer, mainly because I did not know where to enter that code. I looked everywhere for some explanation of the URL Rewrite tool that made sense, but could not find any. I ended up using the HTTP Redirect tool in IIS.

1. Choose your site
2. Click HTTP Redirect in the IIS section (Make sure the Role Service is installed)
3. Check "Redirect requests to this destination"
4. Enter where you want to redirect. In your case "wwww.mysite.com/menu_1/MainScreen.aspx"
5. In Redirect Behavior, I found I had to check "Only redirect requests to content in this directory (not subdirectories), or it would go into a loop. See what works for you.

Hope this helps.

Here is an image from notepad++ when you select text to copy as html.

Actually SELECT ... INTO not only creates the table but will fail if it already exists, so basically the only time you would use it is when the table you are inserting to does not exists.

In regards to your EDIT:

I personally mainly use SELECT ... INTO when I am creating a temp table. That to me is the main use. However I also use it when creating new tables with many columns with similar structures to other tables and then edit it in order to save time.

I'm running OSX. The solutions suggested didn't work for me. I'm using OSX Yosemite. I restarted my Mac then I uninstalled VirtualBox by launching the uninstall script (which is shown when you launch the dmg of VirtualBox) then reinstalled it. I also uninstalled and reinstalled Genymotion. Now everything is working smooth.

To get size of emf file without EMF Image Reader you can use code:

Dimension getImageDimForEmf(final String path) throws IOException {

    ImageInputStream inputStream = new FileImageInputStream(new File(path));

    inputStream.setByteOrder(ByteOrder.LITTLE_ENDIAN);

    // Skip magic number and file size
    inputStream.skipBytes(6*4);

    int left   = inputStream.readInt();
    int top    = inputStream.readInt();
    int right  = inputStream.readInt();
    int bottom = inputStream.readInt();

    // Skip other headers
    inputStream.skipBytes(30);

    int deviceSizeInPixelX = inputStream.readInt();
    int deviceSizeInPixelY = inputStream.readInt();

    int deviceSizeInMlmX = inputStream.readInt();
    int deviceSizeInMlmY = inputStream.readInt();

    int widthInPixel = (int) Math.round(0.5 + ((right - left + 1.0) * deviceSizeInPixelX / deviceSizeInMlmX) / 100.0);
    int heightInPixel = (int) Math.round(0.5 + ((bottom-top + 1.0) * deviceSizeInPixelY / deviceSizeInMlmY) / 100.0);

    inputStream.close();

    return new Dimension(widthInPixel, heightInPixel);
}

In my case in which I synced my mysql data and htdocs to dropbox, I just needed to delete the conflicted files in mysql/data folder and subfolders. The conflicted files can be identified by its names, dropbox will tell you that. It has solved the problem for me.

The best way to do it is to use SerializationUtils from Apache Commons Lang.

To serialize:

byte[] data = SerializationUtils.serialize(yourObject);

To deserialize:

YourObject yourObject = SerializationUtils.deserialize(data)

As mentioned, this requires Commons Lang library. It can be imported using Gradle:

compile 'org.apache.commons:commons-lang3:3.5'

Maven:

<!-- https://mvnrepository.com/artifact/org.apache.commons/commons-lang3 -->
<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.5</version>
</dependency>

Jar file

And more ways mentioned here

Alternatively, the whole collection can be imported. Refer this link

I think is better automate the process:

Add the composer.lock file in your git repository, make sure you use composer.phar install --no-dev when you release, but in you dev machine you could use any composer command without concerns, this will no go to production, the production will base its dependencies in the lock file.

On the server you checkout this specific version or label, and run all the tests before replace the app, if the tests pass you continue the deployment.

If the test depend on dev dependencies, as composer do not have a test scope dependency, a not much elegant solution could be run the test with the dev dependencies (composer.phar install), remove the vendor library, run composer.phar install --no-dev again, this will use cached dependencies so is faster. But that is a hack if you know the concept of scopes in other build tools

Automate this and forget the rest, go drink a beer :-)

PS.: As in the @Sven comment bellow, is not a good idea not checkout the composer.lock file, because this will make composer install work as composer update.

You could do that automation with http://deployer.org/ it is a simple tool.

We use the <strong> tag for text which has high priority for SEO purposes like product name, company name etc, while <b> simple makes it bold.

Similarly, we use <em> for text which has high priority for SEO, while <i> to make the text simply italic.

install -d -m 0777 /your/dir

should give you what you want. Be aware that every user has the right to write add and delete files in that directory.

The PHP way to do it is using the function parse_url, which parses a URL and return its components. Including the query string.

Example:

$url = 'www.mysite.com/category/subcategory?myqueryhash';
echo parse_url($url, PHP_URL_QUERY); # output "myqueryhash"

Why can't you use absolute positioning? Vertical-align does not work (except for tables). Make your container's position: relative. Then absolutely position the internal divs using bottom: 0; Should work like a charm.

EDIT By zoidberg (i will update the answer instead)

<div style="position:relative; border: 1px solid red;width: 40px; height: 40px;">
   <div style="border:1px solid green;position: absolute; bottom: 0; left: 0; width: 20px; height: 20px;"></div>
   <div style="border:1px solid blue;position: absolute; bottom: 0; left: 20px; width: 20px height: 20px;"></div>

On the Mac, I found the keystore file path, password, key alias and key password in an earlier log report before I updated Android Studio.

I launched the Console utility and scrolled down to ~/Library/Logs -> AndroidStudioBeta ->idea.log.1 (or any old log number)

Then I searched for “android.injected.signing.store” and found this from an earlier date:

-Pandroid.injected.signing.store.file=/Users/myuserid/AndroidStudioProjects/keystore/keystore.jks, 
-Pandroid.injected.signing.store.password=mystorepassword, 
-Pandroid.injected.signing.key.alias=myandroidkey, 
-Pandroid.injected.signing.key.password=mykeypassword,

On Windows

you can find your lost key password in below path

Project\.gradle\2.14.1\taskArtifacts\taskArtifacts.bin or ..taskHistory\taskHistory.bin

open the file using appropriate tools e.g. NotePad++ and search with the part of the password that you remember. You will find it definitely. Else, try searching with this string "signingConfig.storePassword".

Note: I have experienced the same and i am able to find it. In case if you didn't find may be you cleared all the cache and temp files.

There was conflict in java version. Resolved after using 1.8 for maven.

How about this?

>>> tuple_list = [("pineapple", 5), ("cherry", 7), ("kumquat", 3), ("plum", 11)]
>>> [x for x, y in enumerate(tuple_list) if y[1] == 7]
[1]
>>> [x for x, y in enumerate(tuple_list) if y[0] == 'kumquat']
[2]

As pointed out in the comments, this would get all matches. To just get the first one, you can do:

>>> [y[0] for y in tuple_list].index('kumquat')
2

There is a good discussion in the comments as to the speed difference between all the solutions posted. I may be a little biased but I would personally stick to a one-liner as the speed we're talking about is pretty insignificant versus creating functions and importing modules for this problem, but if you are planning on doing this to a very large amount of elements you might want to look at the other answers provided, as they are faster than what I provided.

Just the $ (dollar sign) key. You can use A to move to the end of the line and switch to editing mode (Append). To jump the last non-blank character, you can press g then _ keys.

The opposite of A is I (Insert mode at beginning of line), as an aside. Pressing just the ^ will place your cursor at the first non-white-space character of the line.

The html5 spec expressly rejects new lines in the place holder field. Versions of Webkit /will/ insert new lines when presented with line feeds in the placeholder, however this is incorrect behaviour and should not be relied upon.

I guess paragraphs aren't brief enough for w3 ;)

Go to design for that table. Now, on the right, set the ID column as the column in question. It will now auto populate without specification.

It is worth noting that @Marius's second answer could be used as pure Javascript solution.

document.getElementById('elementId').tagName

As with many questions lately, Java 8 to the rescue:

Java 8 added a new static method to java.lang.String which does exactly what you want:

public static String join(CharSequence delimeter, CharSequence... elements);

Using it:

String s = String.join(", ", new String[] {"Hello", "World", "!"});

Results in:

"Hello, World, !"

Use SpecialCells to delete only the rows that are visible after autofiltering:

ActiveSheet.Range("$A$1:$I$" & lines).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

If you have a header row in your range that you don't want to delete, add an offset to the range to exclude it:

ActiveSheet.Range("$A$1:$I$" & lines).Offset(1, 0).SpecialCells _
    (xlCellTypeVisible).EntireRow.Delete

//see also http://stackoverflow.com/questions/641857/javascript-window-resize-event
//see also http://mbccs.blogspot.com/2007/11/fixing-window-resize-event-in-ie.html
/*
Be wary of this:
While you can just hook up to the standard window resize event, you'll find that in IE, the event is fired once for every X and once for every Y axis movement, resulting in a ton of events being fired which might have a performance impact on your site if rendering is an intensive task.
*/

//setup 
window.onresize = function(event) {
    window_resize(event);
}

//timeout wrapper points with doResizeCode as callback
function window_resize(e) { 
     window.clearTimeout(resizeTimeoutId); 
     resizeTimeoutId = window.setTimeout('doResizeCode();', 10); 
}

//wrapper for height/width check
function doResizeCode() {
    if(window.innerHeight > window.innerWidth){
        alert("Please view in landscape");
    }
}

You need to fix one side ( eg height ) and set the other to auto.

Eg

 height: 120px;
 width: auto;

That would scale the image based on one side only. If you find cropping the image acceptable, you can just set

overflow: hidden; 

to the parent element, which would crop out anything that would otherwise exceed its size.

You cannot use the SQL Server agent in SQL Server Express. The way I have done it before is to create a SQL Script, and then run it as a scheduled task each day, you could have multiple scheduled tasks to fit in with your backup schedule/retention. The command I use in the scheduled task is:

"C:\Program Files\Microsoft SQL Server\90\Tools\Binn\SQLCMD.EXE" -i"c:\path\to\sqlbackupScript.sql"

You can find the min/max index and value at the same time if you enumerate the items in the list, but perform min/max on the original values of the list. Like so:

import operator
min_index, min_value = min(enumerate(values), key=operator.itemgetter(1))
max_index, max_value = max(enumerate(values), key=operator.itemgetter(1))

This way the list will only be traversed once for min (or max).

Got to this answer ? probably the answers above are to long ...

just type in :

echo "setenv M2_HOME $M2_HOME" | sudo tee -a /etc/launchd.conf

and restart your mac (thats it!)

restarting is annoying ? just use the command :

grep -E "^setenv" /etc/launchd.conf | xargs -t -L 1 launchctl

and restart IntelliJ IDEA

If you want to make sure your div is not visible by default use ng-cloak class instead. It will work properly with ngShow directive:

<div><div ng-show="myvalue" class="ng-cloak">Here I am</div></div>

This will help....

function setCookie(name,value,days) {
   var expires = "";
   if (days) {
       var date = new Date();
       date.setTime(date.getTime() + (days*24*60*60*1000));
       expires = "; expires=" + date.toUTCString();
   }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}

 function getCookie(name) {
   var nameEQ = name + "=";
   var ca = document.cookie.split(';');
   for(var i=0;i < ca.length;i++) {
       var c = ca[i];
       while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return 
        c.substring(nameEQ.length,c.length);
  }
return null;
}

If you'd like something a bit more readable, you can do this:

A = np.squeeze(np.asarray(M))

Equivalently, you could also do: A = np.asarray(M).reshape(-1), but that's a bit less easy to read.

with the php upload file example would work. In the upload file example instead of using move_uploaded_file to move it from the temporary folder you would just open it:

$attachment = chunk_split(base64_encode(file_get_contents($tmp_file))); 

where $tmp_file = $_FILES['userfile']['tmp_name'];

and send it as an attachment like the rest of the example.

All in one file / self contained:

<? if(isset($_POST['submit'])){
//process and email
}else{
//display form
}
?>

I think its a quick exercise to get what you need working based on the above two available examples.

P.S. It needs to get uploaded somewhere before Apache passes it along to PHP to do what it wants with it. That would be your system's temp folder by default unless it was changed in the config file.

The documentation has been updated. My answer has substantial changes vs the accepted answer: I wanted to reflect documentation is up-to-date, and accepted answer has a few broken links.

Also, I didn't understand when the accepted answer said "it defaults to node server.js". I think the documentation clarifies the default behavior:

npm-start

Start a package

Synopsis

npm start [-- <args>]

Description

This runs an arbitrary command specified in the package's "start" property of its "scripts" object. If no "start" property is specified on the "scripts" object, it will run node server.js.

In summary, running npm start could do one of two things:

1. npm start {command_name}: Run an arbitrary command (i.e. if such command is specified in the start property of package.json's scripts object)
2. npm start: Else if no start property exists (or no command_name is passed): Run node server.js, (which may not be appropriate, for example the OP doesn't have server.js; the OP runs nodeapp.js )
3. I said I would list only 2 items, but are other possibilities (i.e. error cases). For example, if there is no package.json in the directory where you run npm start, you may see an error: npm ERR! enoent ENOENT: no such file or directory, open '.\package.json'

#include <windows.h>
using namespace std;

// The directory path returned by native GetCurrentDirectory() no end backslash
string getCurrentDirectoryOnWindows()
{
    const unsigned long maxDir = 260;
    char currentDir[maxDir];
    GetCurrentDirectory(maxDir, currentDir);
    return string(currentDir);
}

Some of the scenarios, object.item would not be loaded or will be undefined.

Use ng-init

<select ng-init="object.item=2" ng-model="object.item"
ng-options="item.id as item.name for item in list"

Width: 100% will break it when you view on a wider are.

Following is Bootstrap's img-responsive

max-width: 100%; 
display:block; 
height: auto;

I agree with the above comments about overriding toString() on your own classes (and about automating that process as much as possible).

For classes you didn't define, you could write a ToStringHelper class with an overloaded method for each library class you want to have handled to your own tastes:

public class ToStringHelper {
    //... instance configuration here (e.g. punctuation, etc.)
    public toString(List m) {
        // presentation of List content to your liking
    }
    public toString(Map m) {
        // presentation of Map content to your liking
    }
    public toString(Set m) {
        // presentation of Set content to your liking
    }
    //... etc.
}

EDIT: Responding to the comment by xukxpvfzflbbld, here's a possible implementation for the cases mentioned previously.

package com.so.demos;

import java.util.List;
import java.util.Map;
import java.util.Set;

public class ToStringHelper {

    private String separator;
    private String arrow;

    public ToStringHelper(String separator, String arrow) {
        this.separator = separator;
        this.arrow = arrow;
    }

   public String toString(List<?> l) {
        StringBuilder sb = new StringBuilder("(");
        String sep = "";
        for (Object object : l) {
            sb.append(sep).append(object.toString());
            sep = separator;
        }
        return sb.append(")").toString();
    }

    public String toString(Map<?,?> m) {
        StringBuilder sb = new StringBuilder("[");
        String sep = "";
        for (Object object : m.keySet()) {
            sb.append(sep)
              .append(object.toString())
              .append(arrow)
              .append(m.get(object).toString());
            sep = separator;
        }
        return sb.append("]").toString();
    }

    public String toString(Set<?> s) {
        StringBuilder sb = new StringBuilder("{");
        String sep = "";
        for (Object object : s) {
            sb.append(sep).append(object.toString());
            sep = separator;
        }
        return sb.append("}").toString();
    }

}

This isn't a full-blown implementation, but just a starter.

No NSLog or print content will write to system.log, which can be open by Select Simulator -> Debug -> Open System log on Xcode 11.

I figure out a way, write logs into a file and open the xx.log with Terminal.app.Then the logs will present in Terminal.app lively.

I use CocoaLumberjack achieve this.

STEP 1:

Add DDFileLogger DDOSLogger and print logs path. config() should be called when App lunch.

static func config() {
    #if DEBUG
    DDLog.add(DDOSLogger.sharedInstance) // Uses os_log
    let fileLogger: DDFileLogger = DDFileLogger() // File Logger
    fileLogger.rollingFrequency = 60 * 60 * 24 // 24 hours
    fileLogger.logFileManager.maximumNumberOfLogFiles = 7
    DDLog.add(fileLogger)
    DDLogInfo("DEBUG LOG PATH: " + (fileLogger.currentLogFileInfo?.filePath ?? ""))
    #endif
}

STEP 2:

Replace print or NSLog with DDLogXXX.

STEP 3:

$ tail -f {path of log}

Here, message will present in Terminal.app lively.

One thing more. If there is no any message log out, make sure Environment Variables -> OS_ACTIVITY_MODE ISNOT disable.

The parameters of isset() should be separated by a comma sign (,) and not a dot sign (.). Your current code concatenates the variables into a single parameter, instead of passing them as separate parameters.

So the original code evaluates the variables as a unified string value:

isset($_POST['search_term'] . $_POST['postcode']) // Incorrect

While the correct form evaluates them separately as variables:

isset($_POST['search_term'], $_POST['postcode']) // Correct

Breaking down your code example (Explanations are under the line of code.)

import cv2

imports openCV for usage

camera = cv2.VideoCapture(0)

creates an object called camera, of type openCV video capture, using the first camera in the list of cameras connected to the computer.

for i in range(10):

tells the program to loop the following indented code 10 times

    return_value, image = camera.read()

read values from the camera object, using it's read method. it resonds with 2 values save the 2 data values into two temporary variables called "return_value" and "image"

    cv2.imwrite('opencv'+str(i)+'.png', image)

use the openCV method imwrite (that writes an image to a disk) and write an image using the data in the temporary data variable

fewer indents means that the loop has now ended...

del(camera)

deletes the camrea object, we no longer needs it.

you can what you request in many ways, one could be to replace the for loop with a while loop, (running forever, instead of 10 times), and then wait for a keypress (like answered by danidee while I was typing)

or create a much more evil service that hides in the background and captures an image everytime someone presses the keyboard...

After doing all of above I still couldn't login as root remotely, but Telnetting to port 3306 confirmed that MySQL was accepting connections.

I started looking at the users in MySQL and noticed there were multiple root users with different passwords.

select user, host, password from mysql.user;

So in MySQL I set all the passwords for root again and I could finally log in remotely as root.

use mysql;
update user set password=PASSWORD('NEWPASSWORD') where User='root';
flush privileges;

This is when you're working with a FileList Object:

onChange={(event: React.ChangeEvent<HTMLInputElement>): void => {
  const fileListObj: FileList | null = event.target.files;
  if (Object.keys(fileListObj as Object).length > 3) {
    alert('Only three images pleaseeeee :)');
  } else {
    // Do something
  }

  return;
}}

I'm not sure exactly what you mean by "full Git Bash environment", but I get the nice prompt if I do

"C:\Program Files\Git\bin\sh.exe" --login

In PowerShell

& 'C:\Program Files\Git\bin\sh.exe' --login

The --login switch makes the shell execute the login shell startup files.

I achieve this in a view with a subview that is an UIImageView. The image the ImageView is pointing to is a gradient. Then I set a background color in the UIView, and I have a colored gradient view. Next I use the view as I need to and everything I draw will be under this gradient view. By adding a second view on top of the ImageView, you can have some options whether your drawing will be below or above the gradient...

Yes. Empty or incomplete headers or response body typically caused by broken connections or server side crash can cause 502 errors if accessed via a gateway or proxy.

If you have a rogue loop, pause the code in Google Chrome debugger (the small "||" button while in Sources tab).

Switch back to Chrome itself, open "Task Manager" (Shift+ESC), select your tab, click the "End Process" button.

You will get the Aww Snap message and then you can reload (F5).

As others have noted, reloading the page at the point of pausing is the same as restarting the rogue loop and can cause nasty lockups if the debugger also then locks (in some cases leading to restarting chrome or even the PC). The debugger needs a "Stop" button. Nb: The accepted answer is out of date in that some aspects of it are now apparently wrong. If you vote me down, pls explain :).

$("#your-modal-id").modal('hide');

Running this call via class ($(".my-modal")) won't work.

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

In case someone wants numer of whole days as a double (a, b of type DateTime):

 (a.Date - b.Date).TotalDays

window.location.href.split('/');

Will give you an array containing all the URL parts, which you can access like a normal array.

Or an ever more elegant solution suggested by @Dylan, with only the path parts:

window.location.pathname.split('/');

Inside your script file, put all of the commands within parentheses, like this:

(
echo start
ls -l
echo end
) | tee foo.log

One way with bash (version 4+):

foo=bar
echo "${foo^}"

prints:

Bar

Apart from using custom images for bullets, you can also style the ul or li elements one way and then style the contents differently, as seen here.

The benefit is the lack of images for one thing, and also the added control. The disadvantage is that it tends to involve non-semantic markup, except in this case where the anchors are required already.

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

Explanation

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

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

Example

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

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

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

Update: "Loops"

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

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

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

Starting with AspNetCore 2.0, it's recommended to use ContentResult instead of the Produce attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885

This doesn't rely on serialization nor on content negotiation.

[HttpGet]
public ContentResult Index() {
    return new ContentResult {
        ContentType = "text/html",
        StatusCode = (int)HttpStatusCode.OK,
        Content = "<html><body>Hello World</body></html>"
    };
}

I've used this:

RewriteEngine On

# Unless directory, remove trailing slash
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^/]+)/$ http://example.com/folder/$1 [R=301,L]

# Redirect external .php requests to extensionless URL
RewriteCond %{THE_REQUEST} ^(.+)\.php([#?][^\ ]*)?\ HTTP/
RewriteRule ^(.+)\.php$ http://example.com/folder/$1 [R=301,L]

# Resolve .php file for extensionless PHP URLs
RewriteRule ^([^/.]+)$ $1.php [L]

UPDATE: this is not the solution but it's a workaround for a problem that can cause the exception presented in the question.

I've solved changing from Release Configuration to Debug Configuration.

While you can do this with brute casting and suppressed warnings

Map<String,Object> map = new HashMap<String,Object>();
// Two casts in a row.  Note no "new"!
@SuppressWarnings("unchecked")
Map<String,String> newMap = (HashMap<String,String>)(Map)map;  

that's really missing the whole point. :)

An attempt to convert a narrow generic type to a broader generic type means you're using the wrong type in the first place.

As an analogy: Imagine you have a program that does volumous text processing. Imagine that you do first half of the processing using Objects (!!) and then decide to do the second half with correct-typing as a String, so you narrow-cast from Object to String. Fortunately, you can do this is java (easily in this case) - but it's just masking the fact you're using weak-typing in the first half. Bad practice, no argument.

No difference here (just harder to cast). You should always use strong typing. At minimum use some base type - then generics wildcards can be used ("? extends BaseType" or "? super BaseType") to give type-compatability and automatic casting. Even better, use the correct known type. Never use Object unless you have 100% generalised code that can really be used with any type.

Hope that helps! :) :)

Note: The generic strong typing and type-casting will only exist in .java code. After compilation to .class we are left with raw types (Map and HashMap) with no generic type parameters plus automatic type casting of keys and values. But it greatly helps because the .java code itself is strongly-typed and concise.

Use the below function for Kotlin:

private fun animateColorValue(view: View) {
    val colorAnimation =
        ValueAnimator.ofObject(ArgbEvaluator(), Color.GRAY, Color.CYAN)
    colorAnimation.duration = 500L
    colorAnimation.addUpdateListener { animator -> view.setBackgroundColor(animator.animatedValue as Int) }
    colorAnimation.start()
}

Pass whatever view you want to change color of.

i am using NetBeans IDE 7.2.1 as my developer environmental and there you have an option to configure the JForm properties.

in the JForm Properties go to the 'Code' tab and configure the 'Generate Center'. you will need first to set the Form Size Policy to 'Generate Resize Code'.

Michael has given a very comprehensive answer, but I'd like to point out a few things which you can still do to be able to use grids in IE in a nearly painless way.

The repeat functionality is supported

You can still use the repeat functionality, it's just hiding behind a different syntax. Instead of writing repeat(4, 1fr), you have to write (1fr)[4]. That's it. See this series of articles for the current state of affairs: https://css-tricks.com/css-grid-in-ie-debunking-common-ie-grid-misconceptions/

Supporting grid-gap

Grid gaps are supported in all browsers except IE. So you can use the @supports at-rule to set the grid-gaps conditionally for all new browsers:

Example:

.grid {
  display: grid;
}
.item {
  margin-right: 1rem;
  margin-bottom: 1rem;
}
@supports (grid-gap: 1rem) {
  .grid {
    grid-gap: 1rem;
  }
  .item {
    margin-right: 0;
    margin-bottom: 0;
  }
}

It's a little verbose, but on the plus side, you don't have to give up grids altogether just to support IE.

Use Autoprefixer

I can't stress this enough - half the pain of grids is solved just be using autoprefixer in your build step. Write your CSS in a standards-complaint way, and just let autoprefixer do it's job transforming all older spec properties automatically. When you decide you don't want to support IE, just change one line in the browserlist config and you'll have removed all IE-specific code from your built files.

UPDATE yourtable 
SET field_or_column =REPLACE ('current string','findpattern', 'replacepattern') 
WHERE 1

The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.

When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.

I think they using \n anyway even couse it not visible, or maybe they using \r. So just replace \n or \r with <br/>

Using the lambda function to check the character is "_" then only count will be incremented else not a valid character

std::string s = "a_b_c";
size_t count = std::count_if( s.begin(), s.end(), []( char c ){if(c =='_') return true; });
std::cout << "The count of numbers: " << count << std::endl;

Just add another join:

SELECT dashboard_data.headline,
       dashboard_data.message,
       dashboard_messages.image_id,
       images.filename 
FROM dashboard_data 
    INNER JOIN dashboard_messages
            ON dashboard_message_id = dashboard_messages.id 
    INNER JOIN images
            ON dashboard_messages.image_id = images.image_id

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

Another way is to stick it into the command section of the Deployment:

...
command: [ "echo", "
  option = value\n
  other_option = value\n
" ]
...

Alternatively, to make it more ConfigMap-like, use an additional Deployment that will just host that config in the command section and execute kubectl create on it while adding an unique 'version' to its name (like calculating a hash of the content) and modifying all the deployments that use that config:

...
command: [ "/usr/sbin/kubectl-apply-config.sh", "
  option = value\n
  other_option = value\n
" ]
...

I'll probably post kubectl-apply-config.sh if it ends up working.

(don't do that; it looks too bad)

$st = $data->prepare("SELECT * FROM exampleWHERE example LIKE :search LIMIT 10"); 

In "build.gradle" file, change current Kotlin version that line and press synk:

ext.kotlin_version = '1.1.1'

/// That will look like:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.1'
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

@rogerdpack for windows platform it is really hard to find a nc.exe with -X(http_proxy), however, I have found nc can be replaced by ncat, full example as follows:

Host github.com
     HostName github.com
         #ProxyCommand nc -X connect -x 127.0.0.1:1080 %h %p
         ProxyCommand ncat --proxy 127.0.0.1:1080 %h %p
     User git
     Port 22
     IdentityFile D:\Users\Administrator\.ssh\github_key

and ncat with --proxy can do a perfect work

You want to use an App.Config.

When you add a new item to a project there is something called Applications Configuration file. Add that.

Then you add keys in the configuration/appsettings section

Like:

<configuration>
 <appSettings>
  <add key="MyKey" value="false"/>

Access the members by doing

System.Configuration.ConfigurationSettings.AppSettings["MyKey"];

This works in .NET 2 and above.

I was not able to find the logs under Manjaro 20/Arch Linux. Instead i just stopped the docker daemon process and restarted daemon in debug mode with $ sudo dockerd -D to produce logs. It's unfortunate that the official Docker docs don't provide this info for Arch.
This should not only work for Arch, but for other systems in general.

Rclone is what you are looking for. Rclone ("rsync for cloud storage") is a command line program to sync files and directories to and from different cloud storage providers including local filesystems. Rclone was previously known as Swiftsync and has been available since 2013.

This case is valid for Debian.

Add the following to /etc/rc.local

/usr/bin/sudo -u {{user}} /usr/local/bin/forever start {{app path}}

• {{user}} replaces your username.
• {{app path}} replaces your app path. For example, /var/www/test/app.js

You actually can't do what you want with Bash aliases, since aliases are static. Instead, use the function you have created.

Look here for more information: http://www.mactips.org/archives/2008/01/01/increase-productivity-with-bash-aliases-and-functions/. (Yes I know it's mactips.org, but it's about Bash, so don't worry.)

According to the API Reference:

By default the height is calculated from the offset height of the containing element. Defaults to null.

So, you can control it's height according to the parent div using redraw event, which is called when it changes it's size.

I always create an IConfig interface with typesafe properties declared for all configuration values. A Config implementation class then wraps the calls to System.Configuration. All your System.Configuration calls are now in one place, and it is so much easier and cleaner to maintain and track which fields are being used and declare their default values. I write a set of private helper methods to read and parse common data types.

Using an IoC framework you can access the IConfig fields anywhere your in application by simply passing the interface to a class constructor. You're also then able to create mock implementations of the IConfig interface in your unit tests so you can now test various configuration values and value combinations without needing to touch your App.config or Web.config file.

I found the similar problem when downloading .xls file and opened it using xlrd library. Then I tried out the solution of converting .xls into .xlsx as detailed here: how to convert xls to xlsx

It works like a charm and rather than opening .xls, I am working with .xlsx file now using openpyxl library.

Hope it helps to solve your issue.

a->b means (*a).b.

If a is a pointer, a->b is the member b of which a points to.

a can also be a pointer like object (like a vector<bool>'s stub) override the operators.

(if you don't know what a pointer is, you have another question)

• this will get JSON file externally to your javascript variable.
• now this sample_data will contain the values of JSON file.

var sample_data = '';
$.getJSON("sample.json", function (data) {
    sample_data = data;
    $.each(data, function (key, value) {
        console.log(sample_data);

) c on s.age = c.age
order by id

Below expression will work for all popular domains. It will accept following urls:

• www.yourwebsite.com
• http://www.yourwebsite.com
• www.yourwebsite.com
• yourwebsite.com
• yourwebsite.co.in

In addition it will make message with url as link also
e.g. please visit yourwebsite.com
In above example it will make yourwebsite.com as hyperlink

The use of "closed" vs. "open" reflects whether or not we are locked in to using a certain position or data structure (this is an extremely vague description, but hopefully the rest helps).

For instance, the "open" in "open addressing" tells us the index (aka. address) at which an object will be stored in the hash table is not completely determined by its hash code. Instead, the index may vary depending on what's already in the hash table.

The "closed" in "closed hashing" refers to the fact that we never leave the hash table; every object is stored directly at an index in the hash table's internal array. Note that this is only possible by using some sort of open addressing strategy. This explains why "closed hashing" and "open addressing" are synonyms.

Contrast this with open hashing - in this strategy, none of the objects are actually stored in the hash table's array; instead once an object is hashed, it is stored in a list which is separate from the hash table's internal array. "open" refers to the freedom we get by leaving the hash table, and using a separate list. By the way, "separate list" hints at why open hashing is also known as "separate chaining".

In short, "closed" always refers to some sort of strict guarantee, like when we guarantee that objects are always stored directly within the hash table (closed hashing). Then, the opposite of "closed" is "open", so if you don't have such guarantees, the strategy is considered "open".

changing the Binding Type from wsHttpbinding to basichttp binding in the endpoint tag and from wsHttpbinding to mexhttpbinginding in metadata endpoint tag helped to overcome the error. Thank you...

find -name "*Robert*" \( -name "*.pdf" -o -name "*.jpg" \)

The -o repreents an OR condition and you can add as many as you wish within the braces. So this says to find all files containing the word "Robert" anywhere in their names and whose names end in either "pdf" or "jpg".

Above table is an employee salary table with salary1,salary2,salary3,salary4 as columns.Query below will return the max value out of four columns

select  
 (select Max(salval) from( values (max(salary1)),(max(salary2)),(max(salary3)),(max(Salary4)))alias(salval)) as largest_val
 from EmployeeSalary

Running above query will give output as largest_val(10001)

Logic of above query is as below:

select Max(salvalue) from(values (10001),(5098),(6070),(7500))alias(salvalue)

output will be 10001

If anyone is interested in a sortable list with a changing index per listitem (1st, 2nd, 3th etc...:

http://jsfiddle.net/aph0c1rL/1/

$(".sortable").sortable(
{
  handle:         '.handle'
, placeholder:    'sort-placeholder'
, forcePlaceholderSize: true
, start: function( e, ui )
{
    ui.item.data( 'start-pos', ui.item.index()+1 );
}
, change: function( e, ui )
  {
      var seq
      , startPos = ui.item.data( 'start-pos' )
      , $index
      , correction
      ;

      // if startPos < placeholder pos, we go from top to bottom
      // else startPos > placeholder pos, we go from bottom to top and we need to correct the index with +1
      //
      correction = startPos <= ui.placeholder.index() ? 0 : 1;

      ui.item.parent().find( 'li.prize').each( function( idx, el )
      {
        var $this = $( el )
        , $index = $this.index()
        ;

        // correction 0 means moving top to bottom, correction 1 means bottom to top
        //
        if ( ( $index+1 >= startPos && correction === 0) || ($index+1 <= startPos && correction === 1 ) )
        {
          $index = $index + correction;
          $this.find( '.ordinal-position').text( $index + ordinalSuffix( $index ) );
        }

      });

      // handle dragged item separatelly
      seq = ui.item.parent().find( 'li.sort-placeholder').index() + correction;
      ui.item.find( '.ordinal-position' ).text( seq + ordinalSuffix( seq ) );
} );

// this function adds the correct ordinal suffix to the provide number
function ordinalSuffix( number )
{
  var suffix = '';

  if ( number / 10 % 10 === 1 )
  {
    suffix = "th";
  }
  else if ( number > 0 )
  {

    switch( number % 10 )
    {
      case 1:
        suffix = "st";
        break;
      case 2:
        suffix = "nd";
        break;
      case 3:
        suffix = "rd";
        break;
      default:
        suffix = "th";
        break;
    }
  }
  return suffix;
}

Your markup can look like this:

<ul class="sortable ">
<li >        
    <div>
        <span class="ordinal-position">1st</span>
         A header
    </div>
    <div>
        <span class="icon-button handle"><i class="fa fa-arrows"></i></span>
    </div>
    <div class="bpdy" >
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
    </div>
</li>
 <li >        
    <div>
        <span class="ordinal-position">2nd</span>
         A header
    </div>
    <div>
        <span class="icon-button handle"><i class="fa fa-arrows"></i></span>
    </div>
    <div class="bpdy" >
        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod
    </div>
</li>
etc....
</ul>

One more solution, version for the 'years' difference:

SELECT count(*) - 1 FROM (SELECT distinct(date_trunc('year', generate_series('2010-04-01'::timestamp, '2012-03-05', '1 week')))) x

    2

(1 row)

And the same trick for the months:

SELECT count(*) - 1 FROM (SELECT distinct(date_trunc('month', generate_series('2010-04-01'::timestamp, '2012-03-05', '1 week')))) x

   23

(1 row)

In real life query there can be some timestamp sequences grouped by hour/day/week/etc instead of generate_series.

This 'count(distinct(date_trunc('month', ts)))' can be used right in the 'left' side of the select:

SELECT sum(a - b)/count(distinct(date_trunc('month', c))) FROM d

I used generate_series() here just for the brevity.

select{
  *zoom: 1.6;
  *font-size: 9px;
}

If you change properties, size of select will change also in IE7.

You can also add items in code:

cboWhatever.Items.Add("SomeItem");

Also, to add something where you control display/value, (almost categorically needed in my experience) you can do so. I found a good stackoverflow reference here:

Key Value Pair Combobox in WPF

Sum-up code would be something like this:

ComboBox cboSomething = new ComboBox();
cboSomething.DisplayMemberPath = "Key";
cboSomething.SelectedValuePath = "Value";
cboSomething.Items.Add(new KeyValuePair<string, string>("Something", "WhyNot"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Deus", "Why"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Flirptidee", "Stuff"));
cboSomething.Items.Add(new KeyValuePair<string, string>("Fernum", "Blictor"));

Array slicing like in Python (From the rebash library):

array_slice() {
    local __doc__='
    Returns a slice of an array (similar to Python).

    From the Python documentation:
    One way to remember how slices work is to think of the indices as pointing
    between elements, with the left edge of the first character numbered 0.
    Then the right edge of the last element of an array of length n has
    index n, for example:
    ```
    +---+---+---+---+---+---+
    | 0 | 1 | 2 | 3 | 4 | 5 |
    +---+---+---+---+---+---+
    0   1   2   3   4   5   6
    -6  -5  -4  -3  -2  -1
    ```

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1:-2 "${a[@]}")
    1 2 3
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0:1 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 1:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice 2:1 "${a[@]}")" ] && echo empty
    empty
    >>> local a=(0 1 2 3 4 5)
    >>> [ -z "$(array.slice -2:-3 "${a[@]}")" ] && echo empty
    empty
    >>> [ -z "$(array.slice -2:-2 "${a[@]}")" ] && echo empty
    empty

    Slice indices have useful defaults; an omitted first index defaults to
    zero, an omitted second index defaults to the size of the string being
    sliced.
    >>> local a=(0 1 2 3 4 5)
    >>> # from the beginning to position 2 (excluded)
    >>> echo $(array.slice 0:2 "${a[@]}")
    >>> echo $(array.slice :2 "${a[@]}")
    0 1
    0 1

    >>> local a=(0 1 2 3 4 5)
    >>> # from position 3 (included) to the end
    >>> echo $(array.slice 3:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice 3: "${a[@]}")
    3 4 5
    3 4 5

    >>> local a=(0 1 2 3 4 5)
    >>> # from the second-last (included) to the end
    >>> echo $(array.slice -2:"${#a[@]}" "${a[@]}")
    >>> echo $(array.slice -2: "${a[@]}")
    4 5
    4 5

    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -4:-2 "${a[@]}")
    2 3

    If no range is given, it works like normal array indices.
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -1 "${a[@]}")
    5
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice -2 "${a[@]}")
    4
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 0 "${a[@]}")
    0
    >>> local a=(0 1 2 3 4 5)
    >>> echo $(array.slice 1 "${a[@]}")
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice 6 "${a[@]}"; echo $?
    1
    >>> local a=(0 1 2 3 4 5)
    >>> array.slice -7 "${a[@]}"; echo $?
    1
    '
    local start end array_length length
    if [[ $1 == *:* ]]; then
        IFS=":"; read -r start end <<<"$1"
        shift
        array_length="$#"
        # defaults
        [ -z "$end" ] && end=$array_length
        [ -z "$start" ] && start=0
        (( start < 0 )) && let "start=(( array_length + start ))"
        (( end < 0 )) && let "end=(( array_length + end ))"
    else
        start="$1"
        shift
        array_length="$#"
        (( start < 0 )) && let "start=(( array_length + start ))"
        let "end=(( start + 1 ))"
    fi
    let "length=(( end - start ))"
    (( start < 0 )) && return 1
    # check bounds
    (( length < 0 )) && return 1
    (( start < 0 )) && return 1
    (( start >= array_length )) && return 1
    # parameters start with $1, so add 1 to $start
    let "start=(( start + 1 ))"
    echo "${@: $start:$length}"
}
alias array.slice="array_slice"

almost nothing was said about error displaying except check error logs, but there's a rather helpful functionality:

<?php
/* Provoke an error -- bogus SQL syntax */
$stmt = $dbh->prepare('bogus sql');
if (!$stmt) {
    echo "\PDO::errorInfo():\n";
    print_r($dbh->errorInfo());
}
?>

(source link)

it is clear that this code can be modified to be used as exception message or any other kind of error handling

Check your Lazy module , i haved imported AppRoutingModule in the lazy module. After removing the import and imports of AppRoutingModule, Mine started working.

import { AppRoutingModule } from '../app-routing.module'; 

You should stop the submit procedure by returning false on the onsubmit callback.

<script>
    function checkRegistration(){
        if(!form_valid){
            alert('Given data is not correct');
            return false;
        }
        return true;
    }
</script>

<form onsubmit="return checkRegistration()"...

Here you have a fully working example. The form will submit only when you write google into input, otherwise it will return an error:

<script>
    function checkRegistration(){
        var form_valid = (document.getElementById('some_input').value == 'google');
        if(!form_valid){
            alert('Given data is incorrect');
            return false;
        }
        return true;
    }
</script>

<form onsubmit="return checkRegistration()" method="get" action="http://google.com">
    Write google to go to google...<br/>
    <input type="text" id="some_input" value=""/>
    <input type="submit" value="google it"/>
</form>

You need to do two things:

1. Rename and re-order the factor levels before the plot
2. Rename the title of each legend to the same title

The code:

dtt$model <- factor(dtt$model, levels=c("mb", "ma", "mc"), labels=c("MBB", "MAA", "MCC"))

library(ggplot2)
ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha = 0.35, linetype=0)+ 
  geom_line(aes(linetype=model), size = 1) +       
  geom_point(aes(shape=model), size=4)  +      
  theme(legend.position=c(.6,0.8)) +
  theme(legend.background = element_rect(colour = 'black', fill = 'grey90', size = 1, linetype='solid')) +
  scale_linetype_discrete("Model 1") +
  scale_shape_discrete("Model 1") +
  scale_colour_discrete("Model 1")

However, I think this is really ugly as well as difficult to interpret. It's far better to use facets:

ggplot(dtt, aes(x=year, y=V, group = model, colour = model, ymin = lower, ymax = upper)) +
  geom_ribbon(alpha=0.2, colour=NA)+ 
  geom_line() +       
  geom_point()  +      
  facet_wrap(~model)

Use xpath selector (here's quick tutorial) instead of id:

#python:
from selenium.webdriver import Firefox

YOUR_PAGE_URL = 'http://mypage.com/'
NEXT_BUTTON_XPATH = '//input[@type="submit" and @title="next"]'

browser = Firefox()
browser.get(YOUR_PAGE_URL)

button = browser.find_element_by_xpath(NEXT_BUTTON_XPATH)
button.click()

Or, if you use "vanilla" Selenium, just use same xpath selector instead of button id:

NEXT_BUTTON_XPATH = '//input[@type="submit" and @title="next"]'
selenium.click(NEXT_BUTTON_XPATH)
