You can use ->child to get a child element named child.

This element will contain the text of the child element.

But if you try var_dump() on that variable, you will see it is not actually a PHP string.

The easiest way around this is to perform a strval(xml->child); That will convert it to an actual PHP string.

This is useful when debugging when looping your XML and using var_dump() to check the result.

So $s = strval($xml->child);.

You can just do:

echo $xml['token'];

In PHP5, you should use the Document Object Model class instead. Example:

$domDoc = new DOMDocument;
$rootElt = $domDoc->createElement('root');
$rootNode = $domDoc->appendChild($rootElt);

$subElt = $domDoc->createElement('foo');
$attr = $domDoc->createAttribute('ah');
$attrVal = $domDoc->createTextNode('OK');
$attr->appendChild($attrVal);
$subElt->appendChild($attr);
$subNode = $rootNode->appendChild($subElt);

$textNode = $domDoc->createTextNode('Wow, it works!');
$subNode->appendChild($textNode);

echo htmlentities($domDoc->saveXML());

The accepted answer gave me a good start, but brought in more classes and more processing than I would have liked; so this is my interpretation:

$xml_reader = new XMLReader;
$xml_reader->open($feed_url);

// move the pointer to the first product
while ($xml_reader->read() && $xml_reader->name != 'product');

// loop through the products
while ($xml_reader->name == 'product')
{
    // load the current xml element into simplexml and we’re off and running!
    $xml = simplexml_load_string($xml_reader->readOuterXML());

    // now you can use your simpleXML object ($xml).
    echo $xml->element_1;

    // move the pointer to the next product
    $xml_reader->next('product');
}

// don’t forget to close the file
$xml_reader->close();

Found this here ...

Problem: An XML parser returns the error “xmlParseEntityRef: noname”

Cause: There is a stray ‘&’ (ampersand character) somewhere in the XML text eg. some text & some more text

Solution:

• Solution 1: Remove the ampersand.
• Solution 2: Encode the ampersand (that is replace the & character with & ). Remember to Decode when reading the XML text.
• Solution 3: Use CDATA sections (text inside a CDATA section will be ignored by the parser.) eg. <![CDATA[some text & some more text]]>

Note: ‘&’ ‘<' '>‘ will all give problems if not handled correctly.

I had the same problem and I'm using Ubuntu 15.10.

In my case, to solve this issue, I installed the package php7.0-xml using the Synaptic package manager, which include SimpleXml. So, after restart my Apache server, my problem was solved. This package came in the Debian version and you can find it here: https://packages.debian.org/sid/php7.0-xml.

Even though SimpleXML doesn't have a detailed way to remove elements, you can remove elements from SimpleXML by using PHP's unset(). The key to doing this is managing to target the desired element. At least one way to do the targeting is using the order of the elements. First find out the order number of the element you want to remove (for example with a loop), then remove the element:

$target = false;
$i = 0;
foreach ($xml->seg as $s) {
  if ($s['id']=='A12') { $target = $i; break; }
  $i++;
}
if ($target !== false) {
  unset($xml->seg[$target]);
}

You can even remove multiple elements with this, by storing the order number of target items in an array. Just remember to do the removal in a reverse order (array_reverse($targets)), because removing an item naturally reduces the order number of the items that come after it.

Admittedly, it's a bit of a hackaround, but it seems to work fine.

If you are sure that your xml is encoded in UTF-8 but contains bad characters, you can use this function to correct them :

$content = iconv('UTF-8', 'UTF-8//IGNORE', $content);

if you don't know the value of XML Element, you can use

$value = (string) $xml->code[0]->lat;

if (ctype_digit($value)) {
    // the value is probably an integer because consists only of digits
}

It works when you need to determine if value is a number, because (string) will always return string and is_int($value) returns false

You can use Mustache Template Engine and make a Template like:

{{#RECEIVER}}
<RECEIVER>
    <COMPANY>{{{COMPANY}}}</COMPANY>
    <CONTACT>{{{CONTACT}}}</CONTACT>
    <ADDRESS>{{{ADDRESS}}}</ADDRESS>
    <ZIP>{{ZIP}}</ZIP>
    <CITY>{{{CITY}}}</CITY>
</RECEIVER>
{{/RECEIVER}}
{{#DOC}}
<DOC>
    <TEXT>{{{TEXT}}}</TEXT>
    <NUMBER>{{{NUMBER}}}</NUMBER>
</DOC>
{{/DOC}}

Use it like this in PHP:

require_once( __DIR__ .'/../controls/Mustache/Autoloader.php' );
Mustache_Autoloader::register();
$oMustache = new Mustache_Engine();
$sTemplate = implode( '', file( __DIR__ ."/xml.tpl" ));
$return = $oMustache->render($sTemplate, $res);
echo($return);

The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but

for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

• make an ever so slightly more realistic application; com.YourCompany.etc or just com.HelloWorld (Project name: com.HelloWorld and class name: HelloWorld)

or

• when creating the java project; when in the Create Java Project dialog, don't choose Finish but Next, and deselect Create module-info.java file

A few things I've been able to glean: apparently using a "mirror driver" is fast though I'm not aware of an OSS one.

Why is RDP so fast compared to other remote control software?

Also apparently using some convolutions of StretchRect are faster than BitBlt

http://betterlogic.com/roger/2010/07/fast-screen-capture/comment-page-1/#comment-5193

And the one you mentioned (fraps hooking into the D3D dll's) is probably the only way for D3D applications, but won't work with Windows XP desktop capture. So now I just wish there were a fraps equivalent speed-wise for normal desktop windows...anybody?

(I think with aero you might be able to use fraps-like hooks, but XP users would be out of luck).

Also apparently changing screen bit depths and/or disabling hardware accel. might help (and/or disabling aero).

https://github.com/rdp/screen-capture-recorder-program includes a reasonably fast BitBlt based capture utility, and a benchmarker as part of its install, which can let you benchmark BitBlt speeds to optimize them.

VirtualDub also has an "opengl" screen capture module that is said to be fast and do things like change detection http://www.virtualdub.org/blog/pivot/entry.php?id=290

Go to

\node_modules\metro-config\src\defaults\blacklist.js

and replace this

var sharedBlacklist = [
/node_modules[/\\]react[/\\]dist[/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

to

var sharedBlacklist = [
/node_modules[\/\\]react[\/\\]dist[\/\\].*/,
/website\/node_modules\/.*/,
/heapCapture\/bundle\.js/,
/.*\/__tests__\/.*/
];

This is not a best practice and my recommendation is: downgrade node version into 12.9 OR update metro-config since they are fixing the Node issue.

You can use either of the following ways listed below:

I guess, it is not going to work in all cases, but in my particular project it avoided me from duplication of NIB-files:

Somewhere in common.h you can make these defines based off of screen height:

#define HEIGHT_IPHONE_5 568
#define IS_IPHONE   ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
#define IS_IPHONE_5 ([[UIScreen mainScreen] bounds ].size.height == HEIGHT_IPHONE_5)

In your base controller:

- (void)viewDidLoad
{
    [super viewDidLoad];
    if (IS_IPHONE_5) {
        CGRect r = self.view.frame;
        r.size.height = HEIGHT_IPHONE_5 - 20;
        self.view.frame = r;
    }
    // now the view is stretched properly and not pushed to the bottom
    // it is pushed to the top instead...

    // other code goes here...
}

If you want to avoid modulo, you can also use a combination of the four basic operations :)

26 - (26 // 7 * 7) = 5

I had a similar problem with crypto updates. A kludgy hack that gets around this is to include a '+ now() - now()' stunt at the end of the cell formula, with the setting as above to recalculate every minute. This worked for my price updates, but, definitely an ugly hack.

You could create an image of whatever height you wish, and then position that with the CSS background(-position) property like:

#somid { background: url(path/to/img.png) no-repeat center top;

Instead of center topyou can also use pixel or % like 50% 100px.

If Perl is an option:

perl -F, -lane 'print join ",",@F[0,1,2,3,4,5,6,7,8,9,19,20,21,22,23,24,29,32]'

-a autosplits line into @F fields array. Indices start at 0 (not 1 as in awk)
-F, field separator is ,

If your CSV file contains commas within quotes, fully fledged CSV parsers such as Perl's Text::CSV_XS are purpose-built to handle that kind of weirdness.

perl -MText::CSV_XS -lne 'BEGIN{$csv=Text::CSV_XS->new()} if($csv->parse($_)){@f=$csv->fields();print (join ",",@f[0,1,2,3,4,5,6,7,8,9,19,20,21,22,23,24,29,32])}'

As Ennui mentioned, IE 10 supports the -ms prefixed version of Flexbox (IE 11 supports it unprefixed). The errors I can see in your code are:

• You should have display: -ms-flexbox instead of display: -ms-flex
• I think you should specify all 3 flex values, like flex: 0 1 auto to avoid ambiguity

So the final updated code is...

.flexbox form {
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flexbox;
    display: -o-flex;
    display: flex;

    /* Direction defaults to 'row', so not really necessary to specify */
    -webkit-flex-direction: row;
    -moz-flex-direction: row;
    -ms-flex-direction: row;
    -o-flex-direction: row;
    flex-direction: row;
}

.flexbox form input[type=submit] {
    width: 31px;
}

.flexbox form input[type=text] {
    width: auto;

    /* Flex should have 3 values which is shorthand for 
       <flex-grow> <flex-shrink> <flex-basis> */
    -webkit-flex: 1 1 auto;
    -moz-flex: 1 1 auto;
    -ms-flex: 1 1 auto;
    -o-flex: 1 1 auto;
    flex: 1 1 auto;

    /* I don't think you need 'display: flex' on child elements * /
    display: -webkit-flex;
    display: -moz-flex;
    display: -ms-flex;
    display: -o-flex;
    display: flex;
    /**/

Running npm start from react-native directory worked out for me.

As of 2021 insted of null i had to add {} in order to make it work!

axios.post(
        url,
        {},
        {
          params: {
            key,
            checksum
          }
        }
      )
      .then(response => {
        return success(response);
      })
      .catch(error => {
        return fail(error);
      });

This can also happen when you mix -fno-rtti and -frtti code. Then you need to ensure that any class, which type_info is accessed in the -frtti code, have their key method compiled with -frtti. Such access can happen when you create an object of the class, use dynamic_cast etc.

[source]

however, there are still cases where you need the service locator pattern. for example, i have a controller bean, this controller might have some default service beans, which can be dependency injected by configuration. while there could also be many additional or new services this controller can invoke now or later, which then need the service locator to retrieve the service beans.

For floating point data, you can use the new ismembertol function, which computes set membership with a specified tolerance. This is similar to the ismemberf function found in the File Exchange except that it is now built-in to MATLAB. Example:

>> pi_estimate = 3.14159;
>> abs(pi_estimate - pi)
ans =
   5.3590e-08
>> tol = 1e-7;
>> ismembertol(pi,pi_estimate,tol)
ans =
     1

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

As far as I know, JFrame cannot do Modal mode. Use JDialog instead and call setModalityType(Dialog.ModalityType type) to set it to be modal (or not modal).

The original answers to the question are good, but newer versions of mysql (MySQL 5.7.6 on) support geo queries, so you can now use built in functionality rather than doing complex queries.

You can now do something like:

select *, ST_Distance_Sphere( point ('input_longitude', 'input_latitude'), 
                              point(longitude, latitude)) * .000621371192 
          as `distance_in_miles` 
  from `TableName`
having `distance_in_miles` <= 'input_max_distance'
 order by `distance_in_miles` asc

The results are returned in meters. So if you want in KM simply use .001 instead of .000621371192 (which is for miles).

encapsulation is a part of abstraction or we can say its a subset of abstraction

They are different concepts.

• Abstraction is the process of refining away all the unneeded/unimportant attributes of an object and keep only the characteristics best suitable for your domain.

  E.g. for a person: you decide to keep first and last name and SSN. Age, height, weight etc are ignored as irrelevant.

  Abstraction is where your design starts.

• Encapsulation is the next step where it recognizes operations suitable on the attributes you accepted to keep during the abstraction process. It is the association of the data with the operation that act upon them.
  I.e. data and methods are bundled together.

The answer is You can't. Java (in your case JSP) is a server-side scripting language, which means that it is compiled and executed before all javascript code. You can assign javascript variables to JSP variables but not the other way around. If possible, you can have the variable appear in a QueryString or pass it via a form (through a hidden field), post it and extract the variable through JSP that way. But this would require resubmitting the page.

Hope this helps.

Use subprocess.Popen:

import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)

Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.

From the Jenkins website, http://jenkins-ci.org, the following sums it up.

In a nutshell Jenkins CI is the leading open-source continuous integration server. Built with Java, it provides over 300 plugins to support building and testing virtually any project.

Oracle now owns the Hudson trademark, but has licensed it under the Eclipse EPL. Jenkins is on the MIT license. Both Hudson and Jenkins are open-source. Based on the combination of who you work for and personal preference for open-source, the decision is straightforward IMHO.

Hope this was helpful.

Something that has not been mentioned which I believe is useful, if you have two versions of Python installed e.g. both 3.8 and 3.5 there might be two folders called site-packages on your machine. In that case you can specify the python version by using the following:

py -3.5 -c "import site; print(site.getsitepackages()[1])

This is because your row variable/tuple does not contain any value for that index. You can try printing the whole list like print(row) and check how many indexes there exists.

The lambda:

() -> { System.out.println("Do nothing!"); };

actually represents an implementation for an interface like:

public interface Something {
    void action();
}

which is completely different than the one you've defined. That's why you get an error.

Since you can't extend your @FunctionalInterface, nor introduce a brand new one, then I think you don't have much options. You can use the Optional<T> interfaces to denote that some of the values (return type or method parameter) is missing, though. However, this won't make the lambda body simpler.

I think, after the inclusion of 'track by', you can use it in ng-options to get what you wanted, like the following

 <select ng-model="somethingHere" ng-options="option.name for option in options track by option.value" ></select>

This way of doing it is better because when you want to replace the list of strings with list of objects you will just change this to

 <select ng-model="somethingHere" ng-options="object.name for option in options track by object.id" ></select>

where somethingHere is an object with the properties name and id, of course. Please note, 'as' is not used in this way of expressing the ng-options, because it will only set the value and you will not be able to change it when you are using track by

You don't need to call ValidateForm() twice, as you are above. You can just do

if(!ValidateForm()){
..
} else ...

I think that will solve the issue as above it looks like your comparing true/false to the string equivalent 'false'.

Another way to change color of a button if you want to do multiple operations along with color change. Using the Tk().after method and binding a change method allows you to change color and do other operations.

Label.destroy is another example of the after method.

    def export_win():
        //Some Operation
        orig_color = export_finding_graph.cget("background")
        export_finding_graph.configure(background = "green")

        tt = "Exported"
        label = Label(tab1_closed_observations, text=tt, font=("Helvetica", 12))
        label.grid(row=0,column=0,padx=10,pady=5,columnspan=3)

        def change(orig_color):
            export_finding_graph.configure(background = orig_color)

        tab1_closed_observations.after(1000, lambda: change(orig_color))
        tab1_closed_observations.after(500, label.destroy)


    export_finding_graph = Button(tab1_closed_observations, text='Export', command=export_win)
    export_finding_graph.grid(row=6,column=4,padx=70,pady=20,sticky='we',columnspan=3)

You can also revert to the original color.

I had a similar problems after installing Qt in Windows.

This could be because only the Qt creator was installed and not any of the Qt libraries during initial installation. When installing from scratch use the online installer and select the following to install:

1. For starting, select at least one version of Qt libs (ex Qt 5.15.1) and the c++ compiler of choice (ex MinGW 8.1.0 64-bit).

2. Select Developer and Designer Tools. I kept the selected defaults.

Note: The choice of the Qt libs and Tools can also be changed post initial installation using MaintenanceTool.exe under Qt installation dir C:\Qt. See here.

If we are use chosen dropdown list, then we can use below css(No JS/JQuery require)

<select chosen="{width: '100%'}" ng- 
   model="modelName" class="form-control input- 
   sm"
   ng- 
   options="persons.persons as

Why don't you just compile your VB code into a library(.dll).Reference it later from your code and that's it. Managed dlls contain MSIL to which both c# and vb are compiled.

Communicating between different JavaScript execution context was supported even before HTML5 if the documents was of the same origin. If not or you have no reference to the other Window object, then you could use the new postMessage API introduced with HTML5. I elaborated a bit on both approaches in this stackoverflow answer.

What Time Zones?

No where in your question do you mention time zone. What time zone is implied that input string? What time zone do you want for your output? And, UTC is a time zone (or lack thereof depending on your mindset) not a string format.

ISO 8601

Your input string is in ISO 8601 format, except that it lacks an offset from UTC.

Joda-Time

Here is some example code in Joda-Time 2.3 to show you how to handle time zones. Joda-Time has built-in default formatters for parsing and generating String representations of date-time values.

String input = "2013-10-22T01:37:56";
DateTime dateTimeUtc = new DateTime( input, DateTimeZone.UTC );
DateTime dateTimeMontréal = dateTimeUtc.withZone( DateTimeZone.forID( "America/Montreal" );
String output = dateTimeMontréal.toString();

As for generating string representations in other formats, search StackOverflow for "Joda format".

1.7 to 6 update

CLI 1.7 does not support an automatic v6 update. Manually install @angular/cli via your package manager, then run the update migration schematic to finish the process.

npm install @angular/cli@^6.0.0
ng update @angular/cli --migrate-only --from=1

UPDATED 30/04/2017:

1.0 Update

You should now follow the Angular CLI migration guide

UPDATED 04/03/2017:

RC Update

You should follow the Angular CLI RC migration guide

UPDATED 20/02/2017:

Please be aware 1.0.0-beta.32 has breaking changes and has removed ng init and ng update

The pull request here states the following:

BREAKING CHANGE: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Update functionality will return to the CLI, until then manual updates of applications will need done.

The angular-cli CHANGELOG.md states the following:

BREAKING CHANGES - @angular/cli: Removing the ng init & ng update commands because their current implementation causes more problems than it solves. Once RC is released, we won't need to use those to update anymore as the step will be as simple as installing the latest version of the CLI.

UPDATED 17/02/2017:

Angular-cli has now been added to the NPM @angular package. You should now replace the above command with the following -

Global package:

npm uninstall -g angular-cli @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Local project package:

rm -rf node_modules dist # On Windows use rmdir /s /q node_modules dist
npm install --save-dev @angular/cli@latest
npm install
ng init

ORIGINAL ANSWER

You should follow the steps from the README.md on GitHub for updating angular via the angular-cli.

Here they are:

Updating angular-cli

To update angular-cli to a new version, you must update both the global package and your project's local package.

Global package:

npm uninstall -g angular-cli
npm cache clean
npm install -g angular-cli@latest

Local project package:

rm -rf node_modules dist tmp # On Windows use rmdir /s /q node_modules dist tmp
npm install --save-dev angular-cli@latest
npm install
ng init

Running ng init will check for changes in all the auto-generated files created by ng new and allow you to update yours. You are offered four choices for each changed file: y (overwrite), n (don't overwrite), d (show diff between your file and the updated file) and h (help).

Carefully read the diffs for each code file, and either accept the changes or incorporate them manually after ng init finishes.

        while( i <11) {

             int rand=(int)(Math.random()*passswet.length());
             //notice (int) as the original value of Math>random() is double

             t[i] =passswet.charAt(rand);

The following POSIX program will print the names of the files in the current directory:

#define _XOPEN_SOURCE 700
#include <stdio.h>
#include <sys/types.h>
#include <dirent.h>

int main (void)
{
  DIR *dp;
  struct dirent *ep;     
  dp = opendir ("./");

  if (dp != NULL)
  {
    while (ep = readdir (dp))
      puts (ep->d_name);

    (void) closedir (dp);
  }
  else
    perror ("Couldn't open the directory");

  return 0;
}

Tested in Ubuntu 16.04.

I encountered the same problem. Strange, but the reason was that the object Scanner interprets fractions depending on localization of system. If the current localization uses a comma to separate parts of the fractions, the fraction with the dot will turn into type String. Hence the error ...

You can use closures to pass parameters:

iframe.document.addEventListener('click', function(event) {clic(this.id);}, false);

However, I recommend that you use a better approach to access your frame (I can only assume that you are using the DOM0 way of accessing frame windows by their name - something that is only kept around for backwards compatibility):

document.getElementById("myFrame").contentDocument.addEventListener(...);

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

You can functionalize this however you like.

use href with indexof

<script type="text/javascript">
 $(document).ready(function () {
   if(window.location.href.indexOf("added-to-cart=555") > -1) {
   alert("your url contains the added-to-cart=555");
  }
});
</script>

The easiest way would probably be to convert the array into a java.util.ArrayList. Once it is in an arraylist, you can easily leverage the contains method.

public static boolean bagOfWords(String str)
{
    String[] words = {"word1", "word2", "word3", "word4", "word5"};  
    return (Arrays.asList(words).contains(str));
}

Some of the answers here are for infinite page. What Salman is asking is lazy loading of images.

Plugin

Demo

EDIT: How do these plugins work?

This is a simplified explanation:

1. Find window size and find the position of all images and their sizes
2. If the image is not within the window size, replace it with a placeholder of same size
3. When user scrolls down, and position of image < scroll + window height, the image is loaded

attr("dominant-baseline", "central")

You can try this code:

public void itemClicked(View v) {
 //code to check if this checkbox is checked!
 if(((Checkbox)v).isChecked()){
   // code inside if
 }
}

This is my simple solution, adapted from Microsoft (https://code.msdn.microsoft.com/windowsapps/How-to-add-a-hint-text-to-ed66a3c6)

    <Grid Background="White" HorizontalAlignment="Right" VerticalAlignment="Top"  >
        <!-- overlay with hint text -->
        <TextBlock Margin="5,2" MinWidth="50" Text="Suche..." 
                   Foreground="LightSteelBlue" Visibility="{Binding ElementName=txtSearchBox, Path=Text.IsEmpty, Converter={StaticResource MyBoolToVisibilityConverter}}" IsHitTestVisible="False"/>
        <!-- enter term here -->
        <TextBox MinWidth="50" Name="txtSearchBox" Background="Transparent" />
    </Grid>

UPDATE Feb. 2021

As in Activity v1.2.0 and Fragment v1.3.0, the new Activity Result APIs have been introduced.

The Activity Result APIs provide components for registering for a result, launching the result, and handling the result once it is dispatched by the system.

So there is no need of using startActivityForResult and onActivityResult anymore.

In order to use the new API, you need to create an ActivityResultLauncher in your origin Activity, specifying the callback that will be run when the destination Activity finishes and returns the desired data:

private val intentLauncher =
    registerForActivityResult(ActivityResultContracts.StartActivityForResult()) { result ->

        if (result.resultCode == Activity.RESULT_OK) {
            result.data?.getStringExtra("streetkey")
            result.data?.getStringExtra("citykey")
            result.data?.getStringExtra("homekey")
        }
    }

and then, launching your intent whenever you need to:

intentLauncher.launch(Intent(this, YourActivity::class.java))

And to return data from the destination Activity, you just have to add an intent with the values to return to the setResult() method:

val data = Intent()
data.putExtra("streetkey", "streetname")
data.putExtra("citykey", "cityname")
data.putExtra("homekey", "homename")

setResult(Activity.RESULT_OK, data)
finish()

I had the same problem for a long time now, I often needed to mix Matchers and values and I never managed to do that with Mockito.... until recently ! I put the solution here hoping it will help someone even if this post is quite old.

It is clearly not possible to use Matchers AND values together in Mockito, but what if there was a Matcher accepting to compare a variable ? That would solve the problem... and in fact there is : eq

when(recommendedAccessor.searchRecommendedHolidaysProduct(eq(metas), any(List.class), any(HotelsBoardBasisType.class), any(Config.class)))
            .thenReturn(recommendedResults);

In this example 'metas' is an existing list of values

You can also do it using Anaconda:

conda install -c https://conda.binstar.org/menpo opencv=2.4.9

what is about this? \D(\d{5})\D

This will do on:

f 23 23453 234 2344 2534 hallo33333 "50000"

23453, 33333 50000

In your case:

MemoryStream ms = new MemoryStream(buffer);

If it's a single text widget that you want to wrap, you can either use Flexible or Expanded widgets.

Expanded(
  child: Text('Some lengthy text for testing'),
)

or

Flexible(
  child: Text('Some lengthy text for testing'),
)

For multiple widgets, you may choose Wrap widget. For further details checkout this

</script> has to be broken up because otherwise it would end the enclosing <script></script> block too early. Really it should be split between the < and the /, because a script block is supposed (according to SGML) to be terminated by any end-tag open (ETAGO) sequence (i.e. </):

Although the STYLE and SCRIPT elements use CDATA for their data model, for these elements, CDATA must be handled differently by user agents. Markup and entities must be treated as raw text and passed to the application as is. The first occurrence of the character sequence "</" (end-tag open delimiter) is treated as terminating the end of the element's content. In valid documents, this would be the end tag for the element.

However in practice browsers only end parsing a CDATA script block on an actual </script> close-tag.

In XHTML there is no such special handling for script blocks, so any < (or &) character inside them must be &escaped; like in any other element. However then browsers that are parsing XHTML as old-school HTML will get confused. There are workarounds involving CDATA blocks, but it's easiest simply to avoid using these characters unescaped. A better way of writing a script element from script that works on either type of parser would be:

<script type="text/javascript">
    document.write('\x3Cscript type="text/javascript" src="foo.js">\x3C/script>');
</script>

If you use Windows, there some shortcuts, while devtools are opened:

Pressing Ctrl+Shift+D will dock all devtools to left, right, bottom in turn.

Press Ctrl+Shift+F if your JS console disappeared, and you want it docked back to bottom within dev tools.

The easiest answer is number_format().

echo "$ ".number_format($value, 2);

If you want your application to be able to work with multiple currencies and locale-aware formatting (1.000,00 for some of us Europeans for example), it becomes a bit more complex.

There is money_format() but it doesn't work on Windows and relies on setlocale(), which is rubbish in my opinion, because it requires the installation of (arbitrarily named) locale packages on server side.

If you want to seriously internationalize your application, consider using a full-blown internationalization library like Zend Framework's Zend_Locale and Zend_Currency.

Another very basic free profiler: http://expressprofiler.codeplex.com

I shortened Daniel Böhmer's awesome answer to this one-liner:

stat --printf="%y %n\n" $(ls -tr $(find * -type f))

If there are spaces in filenames, you can use this modification:

OFS="$IFS";IFS=$'\n';stat --printf="%y %n\n" $(ls -tr $(find . -type f));IFS="$OFS";

For versions previous to FreeMarker 2.3.7

You can not use ?? to handle missing values, the old syntax is:

<#if userName?exists>
   Hi ${userName}, How are you?
</#if>

If you don't want to touch the original process' stdout and stderr, you can redirect stderr to file descriptor 3 and back:

$ { time { perl -le "print 'foo'; warn 'bar';" 2>&3; }; } 3>&2 2> time.out
foo
bar at -e line 1.
$ cat time.out

real    0m0.009s
user    0m0.004s
sys     0m0.000s

You could use that for a wrapper (e.g. for cronjobs) to monitor runtimes:

#!/bin/bash

echo "[$(date)]" "$@" >> /my/runtime.log

{ time { "$@" 2>&3; }; } 3>&2 2>> /my/runtime.log

As long as you host the PDF the target attribute is the way to go. In other words, for relative files, using the target attribute with _blank value will work just fine.

<e>
  <a target="_blank" alt="StackExchange Handbook" title="StackExchange Handbook"
     href="pdfs/StackExchange_Handbook.pdf">StackExchange Handbook</a>

For absolute paths engines will go to the Unified Resource Locator and open it their. So, suppress the target attribute.

<e>
  <a alt="StackExchange Handbook" title="StackExchange Handbook"
     href="protocol://url/StackExchange_Handbook.pdf">StackExchange Handbook</a>

Browsers will make a rely good job in both cases.

My variation of the solution: (scss)

  .modal {
        .modal-dialog.modal-fs {
            width: 100%;
            margin: 0;
            box-shadow: none;
            height: 100%;
            .modal-content {
                border: none;
                border-radius: 0;
                box-shadow: none;
                box-shadow: none;
                height: 100%;
            }
        }
    }

(css)

.modal .modal-dialog.modal-fs {
  width: 100%;
  margin: 0;
  box-shadow: none;
  height: 100%;
}
.modal .modal-dialog.modal-fs .modal-content {
  border: none;
  border-radius: 0;
  box-shadow: none;
  box-shadow: none;
  height: 100%;
}

Also make sure you don't miss the dnrTV webcast show that Carl Franklin (the man behind .NET rocks) publishes. Even if it's a not a podcast and requires a more attention while watching it it's really informative and if you're into .NET and Microsoft related techniques you'll learn a lot.

I am working on Win 8, use this code. It works for IE and FF, Opera, etc. What I understood are : woff font is light et common on Google fonts.

Go here to convert your ttf font to woff before.

I do recommend BarcodeLibrary

Here is a small piece of code of how to use it.

        BarcodeLib.Barcode barcode = new BarcodeLib.Barcode()
        {
            IncludeLabel = true,
            Alignment = AlignmentPositions.CENTER,
            Width = 300,
            Height = 100,
            RotateFlipType = RotateFlipType.RotateNoneFlipNone,
            BackColor = Color.White,
            ForeColor = Color.Black,
        };

        Image img = barcode.Encode(TYPE.CODE128B, "123456789");

It's a syntactically valid request, but not a satisfiable request. If you look further in that section you see:

If a syntactically valid byte-range-set includes at least one byte- range-spec whose first-byte-pos is less than the current length of the entity-body, or at least one suffix-byte-range-spec with a non- zero suffix-length, then the byte-range-set is satisfiable. Otherwise, the byte-range-set is unsatisfiable. If the byte-range-set is unsatisfiable, the server SHOULD return a response with a status of 416 (Requested range not satisfiable). Otherwise, the server SHOULD return a response with a status of 206 (Partial Content) containing the satisfiable ranges of the entity-body.

So I think in your example, the server should return a 416 since it's not a valid byte range for that file.

parentElement is new to Firefox 9 and to DOM4, but it has been present in all other major browsers for ages.

In most cases, it is the same as parentNode. The only difference comes when a node's parentNode is not an element. If so, parentElement is null.

As an example:

document.body.parentNode; // the <html> element
document.body.parentElement; // the <html> element

document.documentElement.parentNode; // the document node
document.documentElement.parentElement; // null

(document.documentElement.parentNode === document);  // true
(document.documentElement.parentElement === document);  // false

Since the <html> element (document.documentElement) doesn't have a parent that is an element, parentElement is null. (There are other, more unlikely, cases where parentElement could be null, but you'll probably never come across them.)

It's actually pretty easy. (If you're using Angular 2+ anyway.)

Simply add

declare var myGlobalVarName;

Somewhere in the top of your component file (such as after the "import" statements), and you'll be able to access "myGlobalVarName" anywhere inside your component.

I'm new here and don't have the reputation to comment or downvote, but wanted to point out a flaw in the example in Andy White's reply:

try
{
    SomethingThatCausesAnException();
    Assert.Fail("Should have exceptioned above!");
}
catch (Exception ex)
{
    // whatever logging code
}

In all unit testing frameworks I am familiar with, Assert.Fail works by throwing an exception, so the generic catch will actually mask the failure of the test. If SomethingThatCausesAnException() does not throw, the Assert.Fail will, but that will never bubble out to the test runner to indicate failure.

If you need to catch the expected exception (i.e., to assert certain details, like the message / properties on the exception), it's important to catch the specific expected type, and not the base Exception class. That would allow the Assert.Fail exception to bubble out (assuming you aren't throwing the same type of exception that your unit testing framework does), but still allow validation on the exception that was thrown by your SomethingThatCausesAnException() method.

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

The accepted answer works, but you have to do a "Select All" first -- every time -- and I'm way too lazy for that.

And it turns out, it's not super trivial -- I figured I'd post this here in an attempt to save like-minded individuals the 30 minutes it takes to track all this down. -- Also note: this approach restores the original selection when it's done (and it happens so fast, you don't even notice the selection was ever changed).

1.) First, add a custom command to your init script (File->Open Your Init Script, then paste this at the bottom):

atom.commands.add 'atom-text-editor', 'custom:reformat', ->
    editor = atom.workspace.getActiveTextEditor();
    oldRanges = editor.getSelectedBufferRanges();
    editor.selectAll();
    atom.commands.dispatch(atom.views.getView(editor), 'editor:auto-indent')
    editor.setSelectedBufferRanges(oldRanges);

2.) Bind "custom:reformat" to a key (File->Open Your Keymap, then paste this at the bottom):

'atom-text-editor':
    'ctrl-alt-d': 'custom:reformat'

3.) Restart Atom (the init.coffee script only runs when atom is first launched).

There is an optional overload for DataBinder.Eval to supply formatting:

<%# DataBinder.Eval(Container.DataItem, "expression"[, "format"]) %>

The format parameter is a String value, using the value placeholder replacement syntax (called composite formatting) like this:

<asp:Label id="lblNewsDate" runat="server" Text='<%# DataBinder.Eval(Container.DataItem, "publishedDate", "{0:dddd d MMMM}") %>'</label>

I recently saw this one-liner:

def foo(name: str, opts: dict=None) -> str:
    opts = {} if not opts else opts
    pass

\d+

\d represents any digit, + for one or more. If you want to catch negative numbers as well you can use -?\d+.

Note that as a string, it should be represented in C# as "\\d+", or @"\d+"

You would do something like this by tapping into the scroll event handler on window, and using another table with a fixed position to show the header at the top of the page.

HTML:

<table id="header-fixed"></table>

CSS:

#header-fixed {
    position: fixed;
    top: 0px; display:none;
    background-color:white;
}

JavaScript:

var tableOffset = $("#table-1").offset().top;
var $header = $("#table-1 > thead").clone();
var $fixedHeader = $("#header-fixed").append($header);

$(window).bind("scroll", function() {
    var offset = $(this).scrollTop();

    if (offset >= tableOffset && $fixedHeader.is(":hidden")) {
        $fixedHeader.show();
    }
    else if (offset < tableOffset) {
        $fixedHeader.hide();
    }
});

This will show the table head when the user scrolls down far enough to hide the original table head. It will hide again when the user has scrolled the page up far enough again.

Working example: http://jsfiddle.net/andrewwhitaker/fj8wM/

If you have an instance function (i.e. one that gets passed self) you can use self to get a reference to the class using self.__class__

For example in the code below tornado creates an instance to handle get requests, but we can get hold of the get_handler class and use it to hold a riak client so we do not need to create one for every request.

import tornado.web
import riak

class get_handler(tornado.web.requestHandler):
    riak_client = None

    def post(self):
        cls = self.__class__
        if cls.riak_client is None:
            cls.riak_client = riak.RiakClient(pb_port=8087, protocol='pbc')
        # Additional code to send response to the request ...
    

The accept attribute specifies a comma-separated list of content types (MIME types) that the target of the form will process correctly. Unfortunately this attribute is ignored by all the major browsers, so it does not affect the browser's file dialog in any way.

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

In IIS7 with integrated mode, Current is not available in Application_Start. There is a similar thread here.

I stumbled upon the same problem: a page with many independent animations, each one with its own parameters, which must be repeated forever.

Merging this clue with this other clue I found an easy solution: after the end of all your animations the wrapping div is restored, forcing the animations to restart.

All you have to do is to add these few lines of Javascript, so easy they don't even need any external library, in the <head> section of your page:

<script>
setInterval(function(){
var container = document.getElementById('content');
var tmp = container.innerHTML;
container.innerHTML= tmp;
}, 35000 // length of the whole show in milliseconds
);
</script>

BTW, the closing </head> in your code is misplaced: it must be before the starting <body>.

Instead of using regex to remove those "crazy" characters, just convert them to ASCII, which will remove accents, but will keep the letters.

astr <- "Ábcdêãçoàúü"
iconv(astr, from = 'UTF-8', to = 'ASCII//TRANSLIT')

which results in

[1] "Abcdeacoauu"

I have recently written a blog about it for the Laravel5.6. Link to blog is https://www.samundra.com.np/integrating-font-awesome-with-laravel-5.x-using-webpack/1574

The steps are similar to above description. But in my case, I had to do extra steps like configuring the webfonts path to font-awesome in "public" directory. Setting the resource root in Laravel mix etc. You can find the details in the blog.

I am leaving the link here so it helps people for whom the mentioned solutions don't work.

Compare the length using lengthB and length function in oracle.

SELECT * FROM test WHERE length(sampletext) <> lengthb(sampletext)

$scope.rtGo = function(){
            $window.sessionStorage.removeItem('message');
            $window.sessionStorage.removeItem('status');
        }

Passing by reference in the above case is just an alias for the actual object.

You'll be referring to the actual object just with a different name.

There are many advantages which references offer compared to pointer references.

No way to do this that I know of, although I'm very curious to read if anyone has a good answer. I have been thinking about adding something like this to one of the apps my company builds, but have found no good way to do it.

The one thing I can think of (although not directly on point) is that I believe you can limit the total memory usage for a COM+ application in Windows. It would require the app to be written to run in COM+, of course, but it's the closest way I know of.

The working set stuff is good (Job Objects also control working sets), but that's not total memory usage, only real memory usage (paged in) at any one time. It may work for what you want, but afaik it doesn't limit total allocated memory.

First I want to correct Greg: function abc(){} is scoped too — the name abc is defined in the scope where this definition is encountered. Example:

function xyz(){
  function abc(){};
  // abc is defined here...
}
// ...but not here

Secondly, it is possible to combine both styles:

var xyz = function abc(){};

xyz is going to be defined as usual, abc is undefined in all browsers but Internet Explorer — do not rely on it being defined. But it will be defined inside its body:

var xyz = function abc(){
  // xyz is visible here
  // abc is visible here
}
// xyz is visible here
// abc is undefined here

If you want to alias functions on all browsers, use this kind of declaration:

function abc(){};
var xyz = abc;

In this case, both xyz and abc are aliases of the same object:

console.log(xyz === abc); // prints "true"

One compelling reason to use the combined style is the "name" attribute of function objects (not supported by Internet Explorer). Basically when you define a function like

function abc(){};
console.log(abc.name); // prints "abc"

its name is automatically assigned. But when you define it like

var abc = function(){};
console.log(abc.name); // prints ""

its name is empty — we created an anonymous function and assigned it to some variable.

Another good reason to use the combined style is to use a short internal name to refer to itself, while providing a long non-conflicting name for external users:

// Assume really.long.external.scoped is {}
really.long.external.scoped.name = function shortcut(n){
  // Let it call itself recursively:
  shortcut(n - 1);
  // ...
  // Let it pass itself as a callback:
  someFunction(shortcut);
  // ...
}

In the example above we can do the same with an external name, but it'll be too unwieldy (and slower).

(Another way to refer to itself is to use arguments.callee, which is still relatively long, and not supported in the strict mode.)

Deep down, JavaScript treats both statements differently. This is a function declaration:

function abc(){}

abc here is defined everywhere in the current scope:

// We can call it here
abc(); // Works

// Yet, it is defined down there.
function abc(){}

// We can call it again
abc(); // Works

Also, it hoisted through a return statement:

// We can call it here
abc(); // Works
return;
function abc(){}

This is a function expression:

var xyz = function(){};

xyz here is defined from the point of assignment:

// We can't call it here
xyz(); // UNDEFINED!!!

// Now it is defined
xyz = function(){}

// We can call it here
xyz(); // works

Function declaration vs. function expression is the real reason why there is a difference demonstrated by Greg.

Fun fact:

var xyz = function abc(){};
console.log(xyz.name); // Prints "abc"

Personally, I prefer the "function expression" declaration because this way I can control the visibility. When I define the function like

var abc = function(){};

I know that I defined the function locally. When I define the function like

abc = function(){};

I know that I defined it globally providing that I didn't define abc anywhere in the chain of scopes. This style of definition is resilient even when used inside eval(). While the definition

function abc(){};

depends on the context and may leave you guessing where it is actually defined, especially in the case of eval() — the answer is: It depends on the browser.

From the same folder, you can do:

Simple solution for me: sudo docker-compose up

UPDATE 2016-3-14: At some point in the docker install process (or docker-compose ?) there is a suggestion and example to add your username to the "docker" group. This allows you to avoid needing "sudo" before all docker commands, like so:

~ > docker run -it ubuntu /bin/bash
root@665d1ea76b8d:/# date
Mon Mar 14 23:43:36 UTC 2016
root@665d1ea76b8d:/# exit
exit
~ > 

Look carefully at the output of the install commands (both docker & the 2nd install for docker-compose) and you'll find the necessary step. It is also documented here: https://subosito.com/posts/docker-tips/

Sudo? No!

Tired of typing sudo docker everytime you issue a command? Yeah, there is a way for dealing with that. Although naturally docker is require a root user, we can give a root-equivalent group for docker operations.

You can create a group called docker, then add desired user to that group. After restarting docker service, the user will no need to type sudo each time do docker operations. How it looks like on a shell commands? as a root, here you go:

> sudo groupadd docker
> sudo gpasswd -a username docker
> sudo service docker restart 

Done!

UPDATE 2017-3-9

Docker installation instructions have been updated here.

Post-installation steps for Linux

This section contains optional procedures for configuring Linux hosts to work better with Docker.

Manage Docker as a non-root user

The docker daemon binds to a Unix socket instead of a TCP port. By default that Unix socket is owned by the user root and other users can only access it using sudo. The docker daemon always runs as the root user.

If you don’t want to use sudo when you use the docker command, create a Unix group called docker and add users to it. When the docker daemon starts, it makes the ownership of the Unix socket read/writable by the docker group.

To create the docker group and add your user:

# 1. Create the docker group.
$ sudo groupadd docker

# 2. Add your user to the docker group.
$ sudo usermod -aG docker $USER

# 3. Log out and log back in so that your group membership is re-evaluated.

# 4. Verify that you can run docker commands without sudo.
$ docker run hello-world

This command downloads a test image and runs it in a container. When the container runs, it prints an informational message and exits.

add HeaderStyle in your bound field:

    <asp:BoundField HeaderText="UserId"
                DataField="UserId" 
                SortExpression="UserId">

                <HeaderStyle Width="200px" />

</asp:BoundField>

Python 3.6+ provides built-in convenience methods to find and decode the plain text body as in @Todor Minakov's answer. You can use the EMailMessage.get_body() and get_content() methods:

msg = email.message_from_string(s, policy=email.policy.default)
body = msg.get_body(('plain',))
if body:
    body = body.get_content()
print(body)

Note this will give None if there is no (obvious) plain text body part.

If you are reading from e.g. an mbox file, you can give the mailbox constructor an EmailMessage factory:

mbox = mailbox.mbox(mboxfile, factory=lambda f: email.message_from_binary_file(f, policy=email.policy.default), create=False)
for msg in mbox:
    ...

Note you must pass email.policy.default as the policy, since it's not the default...

The problem here is that you are trying to await an array of promises rather than a promise. This doesn't do what you expect.

When the object passed to await is not a Promise, await simply returns the value as-is immediately instead of trying to resolve it. So since you passed await an array (of Promise objects) here instead of a Promise, the value returned by await is simply that array, which is of type Promise<number>[].

What you need to do here is call Promise.all on the array returned by map in order to convert it to a single Promise before awaiting it.

According to the MDN docs for Promise.all:

The Promise.all(iterable) method returns a promise that resolves when all of the promises in the iterable argument have resolved, or rejects with the reason of the first passed promise that rejects.

So in your case:

var arr = [1, 2, 3, 4, 5];

var results: number[] = await Promise.all(arr.map(async (item): Promise<number> => {
    await callAsynchronousOperation(item);
    return item + 1;
}));

This will resolve the specific error you are encountering here.

What about running tmux/GNU Screen within the container? Seems the smoother way to access as many vty as you want with a simple:

$ docker attach {container id}

an simple solution!

setInterval(()=>console.clear(),1500);

Joining on multiple columns in Linq to SQL is a little different.

var query =
    from t1 in myTABLE1List // List<TABLE_1>
    join t2 in myTABLE1List
      on new { t1.ColumnA, t1.ColumnB } equals new { t2.ColumnA, t2.ColumnB }
    ...

You have to take advantage of anonymous types and compose a type for the multiple columns you wish to compare against.

This seems confusing at first but once you get acquainted with the way the SQL is composed from the expressions it will make a lot more sense, under the covers this will generate the type of join you are looking for.

EDIT Adding example for second join based on comment.

var query =
    from t1 in myTABLE1List // List<TABLE_1>
    join t2 in myTABLE1List
      on new { A = t1.ColumnA, B = t1.ColumnB } equals new { A = t2.ColumnA, B = t2.ColumnB }
    join t3 in myTABLE1List
      on new { A = t2.ColumnA, B =  t2.ColumnB } equals new { A = t3.ColumnA, B = t3.ColumnB }
    ...

Thanks All, I found how to do it, which is the same as Dave and Sergey:

I am using QT Creator:

In the main GUI window create using the drag drop GUI and create label (e.g. "myLabel")

In the callback of the button (clicked) do the following using the (*ui) pointer to the user interface window:

void MainWindow::on_pushButton_clicked()
{
     QImage imageObject;
     imageObject.load(imagePath);
     ui->myLabel->setPixmap(QPixmap::fromImage(imageObject));

     //OR use the other way by setting the Pixmap directly

     QPixmap pixmapObject(imagePath");
     ui->myLabel2->setPixmap(pixmapObject);
}

In my case issue was that numberOfRowsInSection was returning similar number of rows after calling tableView.deleteRows(...).

Since this was the required behaviour in my case, I ended up calling tableView.reloadData() instead of tableView.deleteRows(...) in cases where numberOfRowsInSection will remain same after deleting a row.

Use 10.0.2.2 for default AVD and 10.0.3.2 for genymotion.

Android supports all filesystems supported by the Linux kernel, except for a few ported ones like NTFS.

The SD card is formatted as ext3, for example.

You can use grep, as the other answers state. But you don't need grep, awk, sed, perl, cut, or any external tool. You can do it with pure bash.

Try this (semicolons are there to allow you to put it all on one line):

$ while read line;
  do
    if [[ "${line%%:\ *}" == "potato" ]];
    then
      echo ${line##*:\ };
    fi;
  done< file.txt

## tells bash to delete the longest match of ": " in $line from the front.

$ while read line; do echo ${line##*:\ }; done< file.txt
1234
5678
5432
4567
5432
56789

or if you wanted the key rather than the value, %% tells bash to delete the longest match of ": " in $line from the end.

$ while read line; do echo ${line%%:\ *}; done< file.txt
potato
apple
potato
grape
banana
sushi

The substring to split on is ":\ " because the space character must be escaped with the backslash.

You can find more like these at the linux documentation project.

bool Compare(T x, T y) where T : class { return x == y; }

The above will work because == is taken care of in case of user-defined reference types.
In case of value types, == can be overridden. In which case, "!=" should also be defined.

I think that could be the reason, it disallows generic comparison using "==".

Default Bootstrap size classes

You can use btn-lg, btn-sm and btn-xs classes for manipulating with its size.

btn-block

Also, there is a class btn-block which will extend your button to the whole block. It is very convenient in combination with Bootstrap grid.
For example, this code will show a button with the width equal to half of screen for medium and large screens; and will show a full-width button for small screens:

<div class="container">
    <div class="col-xs-12 col-xs-offset-0 col-sm-offset-3 col-sm-6">
        <button class="btn btn-group">Click me!</button>
    </div>
</div>

Check this JSFiddle out. Try to resize frame.

If it is not enough, you can easily create your custom class.

Use traceback.extract_stack() if you want convenient access to module and function names and line numbers.

Use ''.join(traceback.format_stack()) if you just want a string that looks like the traceback.print_stack() output.

Notice that even with ''.join() you will get a multi-line string, since the elements of format_stack() contain \n. See output below.

Remember to import traceback.

Here's the output from traceback.extract_stack(). Formatting added for readability.

>>> traceback.extract_stack()

   ('<string>', 1, '<module>', None),
   ('C:\\Python\\lib\\idlelib\\run.py', 126, 'main', 'ret = method(*args, **kwargs)'),

   ('<pyshell#1>', 1, '<module>', None)

Change the first line to the following as pointed out by Marc B

#!/bin/bash 

Then mark the script as executable and execute it from the command line

chmod +x MigrateNshell.sh
./MigrateNshell.sh

or simply execute bash from the command line passing in your script as a parameter

/bin/bash MigrateNshell.sh

From the two linksResolved Successfully and Naming Convention, I easily solved this same problem which I faced. i.e., for the foreign key name, give as fk_colName_TableName. This naming convention is non-ambiguous and also makes every ForeignKey in your DB Model unique and you will never get this error.

Error 1022: Can't write; duplicate key in table

You can get list of temp tables by following query :

select left(name, charindex('_',name)-1) 
from tempdb..sysobjects
where charindex('_',name) > 0 and
xtype = 'u' and not object_id('tempdb..'+name) is null

Sounds like you almost knew what you wanted to do already, you basically defined it as a regex.

preg_replace("/[^A-Za-z0-9 ]/", '', $string);

you can try writing the command using 'sudo':

sudo mkdir DirName

If your query has any JOINs, Mysql Workbench will not allow you to alter the table, even if your results are all from a single table.

For example, the following query

SELECT u.* FROM users u JOIN passwords p ON u.id=p.user_id WHERE p.password IS NULL;

will not allow you to edit the results or add rows, even though the results are limited to one table. You must specifically do something like:

SELECT * FROM users WHERE id=1012;

and then you can edit the row and add rows to the table.

The other answer is very complete, but here is a rule of thumb:

• call is blocking:

  call('notepad.exe')
  print('hello')  # only executed when notepad is closed
  

• Popen is non-blocking:

  Popen('notepad.exe')
  print('hello')  # immediately executed

// Form A
public void loaddata()
{
    //do what you do in load data in order to update data in datagrid
}

then on Form B define:

// Form B
FormA obj = (FormA)Application.OpenForms["FormA"];

private void button1_Click(object sender, EventArgs e)
{
    obj.loaddata();
    datagridview1.Update();
    datagridview1.Refresh();
}

A join statement is unnecessarily complicated in this situation. The original question only deals with deleting records for a given user from multiple tables at the same time. Intuitively, you might expect something like this to work:

DELETE FROM table1,table2,table3,table4 WHERE user_id='$user_id'

Of course, it doesn't. But rather than writing multiple statements (redundant and inefficient), using joins (difficult for novices), or foreign keys (even more difficult for novices and not available in all engines or existing datasets) you could simplify your code with a LOOP!

As a basic example using PHP (where $db is your connection handle):

$tables = array("table1","table2","table3","table4");
foreach($tables as $table) {
  $query = "DELETE FROM $table WHERE user_id='$user_id'";
  mysqli_query($db,$query);
}

Hope this helps someone!

do this on a new thread (seperate it from main thread)

 new Thread(new Runnable() {

     }
}).run();

To name a few we can use redux-react-session which is having good API for session management like, initSessionService, refreshFromLocalStorage, checkAuth and many other. It also provide some advanced functionality like Immutable JS.

Alternatively we can leverage react-web-session which provides options like callback and timeout.

I went with this solution so I didn't have to include my custom js code within the component other than the jQuery $.getScript function.

Note: Has a dependency on jQuery. So you will need jQuery and jQuery typings.

I have found this is a good way to get around custom or vendor js files that do not have typings available that way TypeScript doesn't scream at you when you go to start your app.

import { Component,AfterViewInit} from '@angular/core'

@Component({
  selector: 'ssContent',
  templateUrl: 'app/content/content.html',
})
export class ContentComponent implements AfterViewInit  {

  ngAfterViewInit(){
    $.getScript('../js/myjsfile.js');
  }
}

Update Actually in my scenario the OnInit lifecycle event worked better because it prevented the script from loading after the views were loaded, which was the case with ngAfterViewInit, and that cause the view to show incorrect element positions prior to the script loading.

ngOnInit() {
    $.getScript('../js/mimity.js');
  }

To complete Zachary's answer, here is a workaround for the "extend in overrides" limitation of eslint config :

overrides: [
  Object.assign(
    {
      files: [ '**/*.test.js' ],
      env: { jest: true },
      plugins: [ 'jest' ],
    },
    require('eslint-plugin-jest').configs.recommended
  )
]

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.

More details about the function utl_raw.cast_to_raw

You cannot TRUNCATE a table that has FK constraints applied on it (TRUNCATE is not the same as DELETE).

To work around this, use either of these solutions. Both present risks of damaging the data integrity.

Option 1:

1. Remove constraints
2. Perform TRUNCATE
3. Delete manually the rows that now have references to nowhere
4. Create constraints

Option 2: suggested by user447951 in their answer

SET FOREIGN_KEY_CHECKS = 0; 
TRUNCATE table $table_name; 
SET FOREIGN_KEY_CHECKS = 1;

I had DependencyResolutionException in Ubuntu Linux when I've installed local artifacts via a shell script. The solution was to delete the local artifacts and install them again "manually" - calling mvn install:install-file via terminal.

First you need to register the style and css using wp_register_script() and wp_register_style() functions

 //registering javascript and css
 wp_register_script ( 'mysample', plugins_url ( 'js/myjs.js', __FILE__ ) );
 wp_register_style ( 'mysample', plugins_url ( 'css/mystyle.css', __FILE__ ) );

After this you can call the wp_enqueue_script() and wp_enqueue_style() functions for loading the js and css in required page

wp_enqueue_script('mysample');
wp_enqueue_style('mysample');

Differences might not be meaningful in a typical use case, but using the standard DOM functionality

$("#el")[0].outerHTML

is about twice as fast as

$("<div />").append($("#el").clone()).html();

so I would go with:

/* 
 * Return outerHTML for the first element in a jQuery object,
 * or an empty string if the jQuery object is empty;  
 */
jQuery.fn.outerHTML = function() {
   return (this[0]) ? this[0].outerHTML : '';  
};

import * as fs from 'fs';
import * as path from 'path';

fs.readFile(path.join(__dirname, "filename.txt"), (err, data) => {
    if (err) throw err;
    console.log(data);
})

EDIT:

consider the project structure:

../readfile/
+-- filename.txt
+-- src
    +-- index.js
    +-- index.ts

consider the index.ts:

import * as fs from 'fs';
import * as path from 'path';

function lookFilesInDirectory(path_directory) {
    fs.stat(path_directory, (err, stat) => {
        if (!err) {
            if (stat.isDirectory()) {
                console.log(path_directory)
                fs.readdirSync(path_directory).forEach(file => {
                    console.log(`\t${file}`);
                });
                console.log();
            }
        }
    });
}

let path_view = './';
lookFilesInDirectory(path_view);
lookFilesInDirectory(path.join(__dirname, path_view));

if you have in the readfile folder and run tsc src/index.ts && node src/index.js, the output will be:

./
        filename.txt
        src

/home/andrei/scripts/readfile/src/
        index.js
        index.ts

that is, it depends on where you run the node.

the __dirname is directory name of the current module.

The System.Linq.Enumerable.Count extension method on IEnumerable<T> has the following implementation:

ICollection<T> c = source as ICollection<TSource>;
if (c != null)
    return c.Count;

int result = 0;
using (IEnumerator<T> enumerator = source.GetEnumerator())
{
    while (enumerator.MoveNext())
        result++;
}
return result;

So it tries to cast to ICollection<T>, which has a Count property, and uses that if possible. Otherwise it iterates.

So your best bet is to use the Count() extension method on your IEnumerable<T> object, as you will get the best performance possible that way.

Focus doesn't work on divs by default. But, according to this, you can make it work:

The focus event is sent to an element when it gains focus. This event is implicitly applicable to a limited set of elements, such as form elements (<input>, <select>, etc.) and links (<a href>). In recent browser versions, the event can be extended to include all element types by explicitly setting the element's tabindex property. An element can gain focus via keyboard commands, such as the Tab key, or by mouse clicks on the element.

http://api.jquery.com/focus/

Nothing dangerous about this. In fact, it is beautiful. You can add default value if that is desirable, for example:

CODE

int x = x1 ?? x2 ?? x3 ?? x4 ?? 0;

As mentioned by @Jim, the file organization is described here. Reproduced for ease of discovery:

For Python modules, the typical layout is:

Lib/<module>.py
Modules/_<module>.c (if there’s also a C accelerator module)
Lib/test/test_<module>.py
Doc/library/<module>.rst

For extension-only modules, the typical layout is:

Modules/<module>module.c
Lib/test/test_<module>.py
Doc/library/<module>.rst

For builtin types, the typical layout is:

Objects/<builtin>object.c
Lib/test/test_<builtin>.py
Doc/library/stdtypes.rst

For builtin functions, the typical layout is:

Python/bltinmodule.c
Lib/test/test_builtin.py

Some exceptions:

builtin type int is at Objects/longobject.c
builtin type str is at Objects/unicodeobject.c
builtin module sys is at Python/sysmodule.c
builtin module marshal is at Python/marshal.c
Windows-only module winreg is at PC/winreg.c

I think you understand everything Interfaces do, but you're not yet imagining the situations in which an Interface is useful.

If you're instantiating, using and releasing an object all within a narrow scope (for example, within one method call), an Interface doesn't really add anything. Like you noted, the concrete class is known.

Where Interfaces are useful is when an object needs to be created one place and returned to a caller that may not care about the implementation details. Let's change your IBox example to an Shape. Now we can have implementations of Shape such as Rectangle, Circle, Triangle, etc., The implementations of the getArea() and getSize() methods will be completely different for each concrete class.

Now you can use a factory with a variety of createShape(params) methods which will return an appropriate Shape depending on the params passed in. Obviously, the factory will know about what type of Shape is being created, but the caller won't have to care about whether it's a circle, or a square, or so on.

Now, imagine you have a variety of operations you have to perform on your shapes. Maybe you need to sort them by area, set them all to a new size, and then display them in a UI. The Shapes are all created by the factory and then can be passed to the Sorter, Sizer and Display classes very easily. If you need to add a hexagon class some time in the future, you don't have to change anything but the factory. Without the Interface, adding another shape becomes a very messy process.

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

Another possibility is that you need to add ?wsdl at the end of your service url for SoapUI. That one got me as I'm used to WCFClient which didn't need it.

Color hexadecimal notation is like following: #AARRGGBB

• A : alpha
• R : red
• G : green
• B : blue

You should first look at how hexadecimal works. You can write at most FF.

Hope this useful for you.

$(document).click(function(e){
    if ($('#news_gallery').on('clicked')) {
        var article = $('#news-article .news-article');
    }  
});

If you're getting a $digest already in progress error, this might help:

return {
        restrict: 'A',
        link: function( $scope, elem, attrs ) {
            elem.ready(function(){

                if(!$scope.$$phase) {
                    $scope.$apply(function(){
                        var func = $parse(attrs.elemReady);
                        func($scope);
                    })
                }
                else {

                    var func = $parse(attrs.elemReady);
                    func($scope);
                }

            })
        }
    }

In your example, from Bar\test.bat, DIR /B /S ..\somefile.txt would return the full path.

I was bored of this problem so I decided to create a shell script to restore my mongo data base easily.

#!/bin/sh
sudo rm /var/lib/mongodb/mongod.lock
sudo -u mongodb mongod -f /etc/mongodb.conf --repair
sudo service mongodb start

Either way works, but many places have coding standards in place that will guide the developer one way or the other. If such a policy is not in place, just follow your heart. One thing, though, it REALLY helps the readability of the code if you do use it. especially if you are not following a naming convention on class-level variable names.

This tutorial details how to update a jar file

jar -uf jar-file <optional_folder_structure>/input-file(s)     

where 'u' means update.

Like this:

long begin, end;
ifstream myfile ("example.txt");
begin = myfile.tellg();
myfile.seekg (0, ios::end);
end = myfile.tellg();
myfile.close();
cout << "size: " << (end-begin) << " bytes." << endl;

MSK,

Have you tried setting a namespace declaration to your member variables like this? :

@XmlElement(required = true, namespace = "http://example.com/a")
protected String username;

@XmlElement(required = true, namespace = "http://example.com/a")
protected String password;

For our project, it solved namespace issues. We also had to create NameSpacePrefixMappers.

You can set the datatable as a datasource to many elements.

For eg

gridView

repeater

datalist

etc etc

If you need to extract data from each row then you can use

table.rows[rowindex][columnindex]

or

if you know the column name

table.rows[rowindex][columnname]

If you need to iterate the table then you can either use a for loop or a foreach loop like

for ( int i = 0; i < table.rows.length; i ++ )
{
    string name = table.rows[i]["columnname"].ToString();
}

foreach ( DataRow dr in table.Rows )
{
    string name = dr["columnname"].ToString();
}

Pass 65536 to mysql_connect as 5th parameter.

Example:

$conn = mysql_connect('localhost','username','password', true, 65536 /* here! */) 
    or die("cannot connect");
mysql_select_db('database_name') or die("cannot use database");
mysql_query("
    INSERT INTO table1 (field1,field2) VALUES(1,2);

    INSERT INTO table2 (field3,field4,field5) VALUES(3,4,5);

    DELETE FROM table3 WHERE field6 = 6;

    UPDATE table4 SET field7 = 7 WHERE field8 = 8;

    INSERT INTO table5
       SELECT t6.field11, t6.field12, t7.field13
       FROM table6 t6
       INNER JOIN table7 t7 ON t7.field9 = t6.field10;

    -- etc
");

When you are working with mysql_fetch_* or mysql_num_rows, or mysql_affected_rows, only the first statement is valid.

For example, the following codes, the first statement is INSERT, you cannot execute mysql_num_rows and mysql_fetch_*. It is okay to use mysql_affected_rows to return how many rows inserted.

$conn = mysql_connect('localhost','username','password', true, 65536) or die("cannot connect");
mysql_select_db('database_name') or die("cannot use database");
mysql_query("
    INSERT INTO table1 (field1,field2) VALUES(1,2);
    SELECT * FROM table2;
");

Another example, the following codes, the first statement is SELECT, you cannot execute mysql_affected_rows. But you can execute mysql_fetch_assoc to get a key-value pair of row resulted from the first SELECT statement, or you can execute mysql_num_rows to get number of rows based on the first SELECT statement.

$conn = mysql_connect('localhost','username','password', true, 65536) or die("cannot connect");
mysql_select_db('database_name') or die("cannot use database");
mysql_query("
    SELECT * FROM table2;
    INSERT INTO table1 (field1,field2) VALUES(1,2);
");

ListBox will try to expand in height that is available.. When you set the Height property of ListBox you get a scrollviewer that actually works...

If you wish your ListBox to accodate the height available, you might want to try to regulate the Height from your parent controls.. In a Grid for example, setting the Height to Auto in your RowDefinition might do the trick...

HTH

The two forms are the same with one exception: temporarily, the new (Object *) has an undefined value when the creation and assignment are separate. The compiler may combine them back together, since the undefined pointer is not particularly useful. This does not relate to global variables (unless the declaration is global, in which case it's still true for both forms).

You can use pyuic4 command on shell: pyuic4 input.ui -o output.py

Simply declare length to be a cons, if it is not then you should be allocating memory dynamically

You can use:

<script type="text/javascript">
    function prepareFrame() {
        var ifrm = document.createElement("iframe");
        ifrm.setAttribute("src", "http://google.com/");
        ifrm.style.width = "640px";
        ifrm.style.height = "480px";
        document.body.appendChild(ifrm);
    }
</script> 

also check basics of the iFrame element

How about the JDK source code?

Update 2019

The :has() pseudo-selector is propsed in the CSS Selectors 4 spec, and will address this use case once implemented.

To use it, we will write something like:

.foo > .bar:has(> .baz) { /* style here */ }

In a structure like:

<div class="foo">
  <div class="bar">
    <div class="baz">Baz!</div>
  </div>
</div>

This CSS will target the .bar div - because it both has a parent .foo and from its position in the DOM, > .baz resolves to a valid element target.

Original Answer (left for historical purposes) - this portion is no longer accurate

For completeness, I wanted to point out that in the Selectors 4 specification (currently in proposal), this will become possible. Specifically, we will gain Subject Selectors, which will be used in the following format:

!div > span { /* style here */

The ! before the div selector indicates that it is the element to be styled, rather than the span. Unfortunately, no modern browsers (as of the time of this posting) have implemented this as part of their CSS support. There is, however, support via a JavaScript library called Sel, if you want to go down the path of exploration further.

Use:

function getvalues(){
var inps = document.getElementsByName('pname[]');
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
    alert("pname["+i+"].value="+inp.value);
}
}

Here is Demo.

This error sometimes occurs in a situation like this:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

static void init_random(uint32_t initseed=0)
{
    if (initseed==0)
    {
        struct timeval tv;
        gettimeofday(&tv, NULL);
        seed=(uint32_t) (4223517*getpid()*tv.tv_sec*tv.tv_usec);
    }
    else
        seed=initseed;
#if !defined(CYGWIN) && !defined(__INTERIX)
    //seed=42
    //SG_SPRINT("initializing random number generator with %d (seed size %d)\n", seed, RNG_SEED_SIZE)
    initstate(seed, CMath::rand_state, RNG_SEED_SIZE);
#endif
}

If the following code lines not run in the run-time:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

you will face with an error in your code like something as follows; because initstate is placed in the stdlib.h file and it's not included:

In file included from ../../shogun/features/SubsetStack.h:14:0, 
                 from ../../shogun/features/Features.h:21,

Here is a little lib to load javascript and CSS files dynamically:

https://github.com/todotresde/javascript-loader

I guess is usefull to load css and js files in order and dynamically.

Support to extend to load any lib you want, and not just the main file, you can use it to load custom files.

I.E.:

<html>
<head>
    <script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
    <script src="scripts/javascript-loader.js" type="text/javascript" charset="utf-8" ></script>    
    <script type="text/javascript">
        $(function() {

            registerLib("threejs", test);

            function test(){
                console.log(THREE);
            }

            registerLib("tinymce", draw);

            function draw(){
                tinymce.init({selector:'textarea'});
            }

        }); 
    </script>
</head>
<body>
    <textarea>Your content here.</textarea>
</body>

If you are running a website, you could also try to set your application pool to disable 32-bit Applications (under advanced settings of a pool).

I got the same error when I was calling

this.handleClick = this.handleClick.bind(this);

in my constructor when handleClick didn't exist

(I had erased it and had accidentally left the "this" binding statement in my constructor).

Solution = remove the "this" binding statement.

In addition of Stack: to avoid floating container on keyboard, use this

return Scaffold(
    appBar: getAppBar(title),
    resizeToAvoidBottomInset: false,
    body:

A possible solution:

dir|find "bytes free"

a more "advanced solution", for Windows Xp and beyond:

wmic /node:"%COMPUTERNAME%" LogicalDisk Where DriveType="3" Get DeviceID,FreeSpace|find /I "c:"

The Windows Management Instrumentation Command-line (WMIC) tool (Wmic.exe) can gather vast amounts of information about about a Windows Server 2003 as well as Windows XP or Vista. The tool accesses the underlying hardware by using Windows Management Instrumentation (WMI). Not for Windows 2000.

As noted by Alexander Stohr in the comments:

• WMIC can see policy based restrictions as well. (even if 'dir' will still do the job),
• 'dir' is locale dependent.

Do you know if the renew button only appeared when the profile expired? I've a profile that will expire soon, but no "renew" button is shown at the moment.

Just read elsewhere that apparently this is the case.

That's the SHOW CREATE TABLE query. You can query the SCHEMA TABLES, too.

SHOW CREATE TABLE YourTableName;

function removeParam(parameter)
{
  var url=document.location.href;
  var urlparts= url.split('?');

 if (urlparts.length>=2)
 {
  var urlBase=urlparts.shift(); 
  var queryString=urlparts.join("?"); 

  var prefix = encodeURIComponent(parameter)+'=';
  var pars = queryString.split(/[&;]/g);
  for (var i= pars.length; i-->0;)               
      if (pars[i].lastIndexOf(prefix, 0)!==-1)   
          pars.splice(i, 1);
  url = urlBase+'?'+pars.join('&');
  window.history.pushState('',document.title,url); // added this line to push the new url directly to url bar .

}
return url;
}

This will resolve your problem

Thanks Chad! To show all the errors associated with the key, here's what I came up with. For some reason the base Html.ValidationMessage helper only shows the first error associated with the key.

    <%= Html.ShowAllErrors(mykey) %>

HtmlHelper:

    public static String ShowAllErrors(this HtmlHelper helper, String key) {
        StringBuilder sb = new StringBuilder();
        if (helper.ViewData.ModelState[key] != null) {
            foreach (var e in helper.ViewData.ModelState[key].Errors) {
                TagBuilder div = new TagBuilder("div");
                div.MergeAttribute("class", "field-validation-error");
                div.SetInnerText(e.ErrorMessage);
                sb.Append(div.ToString());
            }
        }
        return sb.ToString();
    }

While writing a monitoring tool, i took a slightly different approach.

It felt a bit wasteful to spin up an extra thread just to use WaitForSingleObject or even the RegisterWaitForSingleObject (which does that for you). Since in my case i don't need to know the exact instant a process has closed, just that it indeed HAS closed.

I'm using the GetProcessTimes() instead:

https://msdn.microsoft.com/en-us/library/windows/desktop/ms683223(v=vs.85).aspx

GetProcessTimes() will return a FILETIME struct for the process's ExitTime only if the process has actually exited. So is just a matter of checking if the ExitTime struct is populated and if the time isn't 0;

This solution SHOULD account the case where a process has been killed but it's PID was reused by another process. GetProcessTimes needs a handle to the process, not the PID. So the OS should know that the handle is to a process that was running at some point, but not any more, and give you the exit time.

Relying on the ExitCode felt dirty :/

One can configure Git to automatically remove references to deleted remote branches when fetching:

git config --global fetch.prune true

When calling git fetch or git pull afterwards, references to deleted remote branches get removed automatically.

I tend to do this (if I really, really had to):

for i in some_var:
   if type(i) == type(list()):
       #do something with a list
   elif type(i) == type(tuple()):
       #do something with a tuple
   elif type(i) == type(str()):
       #here's your string

When you say the first three columns, do you mean your SUM columns? If so, add ELSE 0 to your CASE statements. The SUM of a NULL value is NULL.

sum(case when c.runstatus = 'Succeeded' then 1 else 0 end) as Succeeded, 
sum(case when c.runstatus = 'Failed' then 1 else 0 end) as Failed, 
sum(case when c.runstatus = 'Cancelled' then 1 else 0 end) as Cancelled,

You may need to do AndroidStudio - Build - Clean

If you updated manifest through the filesystem or Git it won't pick up the changes.

Generally, FileMode.Create is what you're looking for.

By failing to provide a decent solution, you just end up with something worse IMHO.

The common work around is as follows.

T[] ts = new T[n];

is replaced with (assuming T extends Object and not another class)

T[] ts = (T[]) new Object[n];

I prefer the first example, however more academic types seem to prefer the second, or just prefer not to think about it.

Most of the examples of why you can't just use an Object[] equally apply to List or Collection (which are supported), so I see them as very poor arguments.

Note: this is one of the reasons the Collections library itself doesn't compile without warnings. If you this use-case cannot be supported without warnings, something is fundamentally broken with the generics model IMHO.

Your best bet over here to install XAMPP..Follow the link download it , it has an instruction file as well. You can setup your own MY SQL database and then connect to on your local machine.

https://www.apachefriends.org/download.html

You can use recursion to do this. I haven't verified the following, but it should give you the right idea:

MergeListOfDf = function( data , ... )
{
    if ( length( data ) == 2 ) 
    {
        return( merge( data[[ 1 ]] , data[[ 2 ]] , ... ) )
    }    
    return( merge( MergeListOfDf( data[ -1 ] , ... ) , data[[ 1 ]] , ... ) )
}

You cannot use the VB line-continuation character inside of a string.

SqlQueryString = "Insert into Employee values(" & txtEmployeeNo.Value & _
"','" & txtContractStartDate.Value &  _
"','" & txtSeatNo.Value & _
"','" & txtFloor.Value & "','" & txtLeaves.Value & "')"

Now it's possible and supported by all major browsers: https://developer.mozilla.org/en-US/docs/Web/API/File/File

var file = new File(["foo"], "foo.txt", {
  type: "text/plain",
});

If you use an = statement to assign a value to a var with an object on the right side, javascript will not copy but reference the object.

You can use lodash's clone method

var obj = {a: 25, b: 50, c: 75};
var A = _.clone(obj);

Or lodash's cloneDeep method if your object has multiple object levels

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.cloneDeep(obj);

Or lodash's merge method if you mean to extend the source object

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.merge({}, obj, {newkey: "newvalue"});

Or you can use jQuerys extend method:

var obj = {a: 25, b: 50, c: 75};
var A = $.extend(true,{},obj);

Here is jQuery 1.11 extend method's source code :

jQuery.extend = jQuery.fn.extend = function() {
    var src, copyIsArray, copy, name, options, clone,
        target = arguments[0] || {},
        i = 1,
        length = arguments.length,
        deep = false;

    // Handle a deep copy situation
    if ( typeof target === "boolean" ) {
        deep = target;

        // skip the boolean and the target
        target = arguments[ i ] || {};
        i++;
    }

    // Handle case when target is a string or something (possible in deep copy)
    if ( typeof target !== "object" && !jQuery.isFunction(target) ) {
        target = {};
    }

    // extend jQuery itself if only one argument is passed
    if ( i === length ) {
        target = this;
        i--;
    }

    for ( ; i < length; i++ ) {
        // Only deal with non-null/undefined values
        if ( (options = arguments[ i ]) != null ) {
            // Extend the base object
            for ( name in options ) {
                src = target[ name ];
                copy = options[ name ];

                // Prevent never-ending loop
                if ( target === copy ) {
                    continue;
                }

                // Recurse if we're merging plain objects or arrays
                if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) ) ) {
                    if ( copyIsArray ) {
                        copyIsArray = false;
                        clone = src && jQuery.isArray(src) ? src : [];

                    } else {
                        clone = src && jQuery.isPlainObject(src) ? src : {};
                    }

                    // Never move original objects, clone them
                    target[ name ] = jQuery.extend( deep, clone, copy );

                // Don't bring in undefined values
                } else if ( copy !== undefined ) {
                    target[ name ] = copy;
                }
            }
        }
    }

    // Return the modified object
    return target;
};

If you want to modify the original array instead of returning a new array, use .push()...

array1.push.apply(array1, array2);
array1.push.apply(array1, array3);

I used .apply to push the individual members of arrays 2 and 3 at once.

or...

array1.push.apply(array1, array2.concat(array3));

To deal with large arrays, you can do this in batches.

for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
    array1.push.apply(array1, to_add.slice(n, n+300));
}

If you do this a lot, create a method or function to handle it.

var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);

Object.defineProperty(Array.prototype, "pushArrayMembers", {
    value: function() {
        for (var i = 0; i < arguments.length; i++) {
            var to_add = arguments[i];
            for (var n = 0; n < to_add.length; n+=300) {
                push_apply(this, slice_call(to_add, n, n+300));
            }
        }
    }
});

and use it like this:

array1.pushArrayMembers(array2, array3);

var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
    value: function() {_x000D_
        for (var i = 0; i < arguments.length; i++) {_x000D_
            var to_add = arguments[i];_x000D_
            for (var n = 0; n < to_add.length; n+=300) {_x000D_
                push_apply(this, slice_call(to_add, n, n+300));_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_
_x000D_
document.body.textContent = JSON.stringify(array1, null, 4);

When I see things like this - it is usually because there are backslashes in the path which get converted.

For example - the following will fail - because \t in the string is converted to TAB character.

>>> import ctypes
>>> ctypes.windll.LoadLibrary("c:\tools\depends\depends.dll")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "c:\tools\python271\lib\ctypes\__init__.py", line 431, in LoadLibrary
    return self._dlltype(name)
  File "c:\tools\python271\lib\ctypes\__init__.py", line 353, in __init__
    self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found

There are 3 solutions (if that is the problem)

a) Use double slashes...

>>> import ctypes
>>> ctypes.windll.LoadLibrary("c:\\tools\\depends\\depends.dll")

b) use forward slashes

>>> import ctypes
>>> ctypes.windll.LoadLibrary("c:/tools/depends/depends.dll")

c) use RAW strings (prefacing the string with r

>>> import ctypes
>>> ctypes.windll.LoadLibrary(r"c:\tools\depends\depends.dll")

While this third one works - I have gotten the impression from time to time that it is not considered 'correct' because RAW strings were meant for regular expressions. I have been using it for paths on Windows in Python for years without problem :) )

Try using matplotlib.pyplot.ticklabel_format:

import matplotlib.pyplot as plt
...
plt.ticklabel_format(style='sci', axis='x', scilimits=(0,0))

This applies scientific notation (i.e. a x 10^b) to your x-axis tickmarks

I get that exception too and cleared things up like this

var identity = User.Identity as ClaimsIdentity;
var newIdentity = new ClaimsIdentity(identity.AuthenticationType, identity.NameClaimType, identity.RoleClaimType);
newIdentity.AddClaims(identity.Claims.Where(c => false == (c.Type == claim.Type && c.Value == claim.Value)));
// the claim has been removed, you can add it with a new value now if desired
AuthenticationManager.SignOut(identity.AuthenticationType);
AuthenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = isPersistent }, newIdentity);
