Actually, I needed the following...get rid of the decimals without rounding so "12.23" needs to show as "12". In SSRS, do not format the number as a percent. Leave the formatting as default (no formatting applied) then in the expression do the following: =Fix(Fields!PctAmt.Value*100))

Multiply the number by 100 then apply the FIX function in SSRS which returns only the integer portion of a number.

1. LogiReport
2. MonoReport

Try passing multiple values via url:

/ReportServer?%2fService+Specific+Reports%2fFilings%2fDrillDown%2f&StartDate=01/01/2010&EndDate=01/05/2010&statuses=1&statuses=2&rs%3AFormat=PDF

This should work.

What worked for me was:

• Go to Site Setting
• Click on "Configure site-wide security"
• Click "New Role Assignment" button in top bar
• Give the new role the following name "Everyone"
• Of the available roles, grant it "System User" only
• Click "Apply"

That should do it,

Good luck!

That's funny you asked this, I just did this recently for my work's site and I was thinking I should write a tutorial... Here is how to do it with PHP/Imagick, which uses ImageMagick:

$usmap = '/path/to/blank/us-map.svg';
$im = new Imagick();
$svg = file_get_contents($usmap);

/*loop to color each state as needed, something like*/ 
$idColorArray = array(
     "AL" => "339966"
    ,"AK" => "0099FF"
    ...
    ,"WI" => "FF4B00"
    ,"WY" => "A3609B"
);

foreach($idColorArray as $state => $color){
//Where $color is a RRGGBB hex value
    $svg = preg_replace(
         '/id="'.$state.'" style="fill:#([0-9a-f]{6})/'
        , 'id="'.$state.'" style="fill:#'.$color
        , $svg
    );
}

$im->readImageBlob($svg);

/*png settings*/
$im->setImageFormat("png24");
$im->resizeImage(720, 445, imagick::FILTER_LANCZOS, 1);  /*Optional, if you need to resize*/

/*jpeg*/
$im->setImageFormat("jpeg");
$im->adaptiveResizeImage(720, 445); /*Optional, if you need to resize*/

$im->writeImage('/path/to/colored/us-map.png');/*(or .jpg)*/
$im->clear();
$im->destroy();

the steps regex color replacement may vary depending on the svg path xml and how you id & color values are stored. If you don't want to store a file on the server, you can output the image as base 64 like

<?php echo '<img src="data:image/jpg;base64,' . base64_encode($im) . '"  />';?>

(before you use clear/destroy) but ie has issues with PNG as base64 so you'd probably have to output base64 as jpeg

you can see an example here I did for a former employer's sales territory map:

Start: https://upload.wikimedia.org/wikipedia/commons/1/1a/Blank_US_Map_(states_only).svg

Finish:

Edit

Since writing the above, I've come up with 2 improved techniques:

1) instead of a regex loop to change the fill on state , use CSS to make style rules like

<style type="text/css">
#CA,#FL,HI{
    fill:blue;
}
#Al, #NY, #NM{
    fill:#cc6699;
}
/*etc..*/
</style>

and then you can do a single text replace to inject your css rules into the svg before proceeding with the imagick jpeg/png creation. If the colors don't change, check to make sure you don't have any inline fill styles in your path tags overriding the css.

2) If you don't have to actually create a jpeg/png image file (and don't need to support outdated browsers), you can manipulate the svg directly with jQuery. You can't access the svg paths when embedding the svg using img or object tags, so you'll have to directly include the svg xml in your webpage html like:

<div>
<?php echo file_get_contents('/path/to/blank/us-map.svg');?>
</div>

then changing the colors is as easy as:

<script type="text/javascript" src="/path/to/jquery.js"></script>
<script type="text/javascript">
    $('#CA').css('fill', 'blue');
    $('#NY').css('fill', '#ff0000');
</script>

This error occurs because you are using a normal string as a path. You can use one of the three following solutions to fix your problem:

1: Just put r before your normal string it converts normal string to raw string:

pandas.read_csv(r"C:\Users\DeePak\Desktop\myac.csv")

2:

pandas.read_csv("C:/Users/DeePak/Desktop/myac.csv")

3:

pandas.read_csv("C:\\Users\\DeePak\\Desktop\\myac.csv")

try this while compare date should be iso format "yyyy-MM-dd" if you want to compare only dates use this datehelper

In addition to the good advice already given, I would add this:

It is probably best to avoid using require() unless you actually will be using the value it returns e.g in some error checking loop such as given by thierry.

In most other cases it is better to use library(), because this will give an error message at package loading time if the package is not available. require() will just fail without an error if the package is not there. This is the best time to find out if the package needs to be installed (or perhaps doesn't even exist because it it spelled wrong). Getting error feedback early and at the relevant time will avoid possible headaches with tracking down why later code fails when it attempts to use library routines

This code is based on brilliant existing answer from @bukzor. I just added custom render for datetime.datetime type into Oracle's TO_DATE().

Feel free to update code to suit your database:

This is about the best you can do:

if (!mail(...)) {
   // Reschedule for later try or panic appropriately!
}

http://php.net/manual/en/function.mail.php

mail() returns TRUE if the mail was successfully accepted for delivery, FALSE otherwise.

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

If you need to suppress warnings, you can use:

if (!@mail(...))

Be careful though about using the @ operator without appropriate checks as to whether something succeed or not.

If mail() errors are not suppressible (weird, but can't test it right now), you could:

a) turn off errors temporarily:

$errLevel = error_reporting(E_ALL ^ E_NOTICE);  // suppress NOTICEs
mail(...);
error_reporting($errLevel);  // restore old error levels

b) use a different mailer, as suggested by fire and Mike.

If mail() turns out to be too flaky and inflexible, I'd look into b). Turning off errors is making debugging harder and is generally ungood.

In addition to cookies and localStorage, there's at least one other place you can store "semi-persistent" client data: window.name. Any string value you assign to window.name will stay there until the window is closed.

To test it out, just open the console and type window.name = "foo", then refresh the page and type window.name; it should respond with foo.

This is a bit of a hack, but if you don't want cookies filled with unnecessary data being sent to the server with every request, and if you can't use localStorage for whatever reason (legacy clients), it may be an option to consider.

window.name has another interesting property: it's visible to windows served from other domains; it's not subject to the same-origin policy like nearly every other property of window. So, in addition to storing "semi-persistent" data there while the user navigates or refreshes the page, you can also use it for CORS-free cross-domain communication.

Note that window.name can only store strings, but with the wide availability of JSON, this shouldn't be much of an issue even for complex data.

Angular solution

You can fix it like this:

$scope.hoverIn = function(){
    this.hoverEdit = true;
};

$scope.hoverOut = function(){
    this.hoverEdit = false;
};

Inside of ngMouseover (and similar) functions context is a current item scope, so this refers to the current child scope.

Also you need to put ngRepeat on li:

<ul>
    <li ng-repeat="task in tasks" ng-mouseover="hoverIn()" ng-mouseleave="hoverOut()">
        {{task.name}}
        <span ng-show="hoverEdit">
            <a>Edit</a>
        </span>
    </li>
</ul>

Demo

CSS solution

However, when possible try to do such things with CSS only, this would be the optimal solution and no JS required:

ul li span {display: none;}
ul li:hover span {display: inline;}

CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines.

Excel will actually ask you whether you want to proceed when importing more than 1 million data rows. It suggests to import the remaining data by using the text import wizard again - you will need to set the appropriate line offset.

In a single line you could do:

private static File[] bar(){
    return new File[]{};
}

I created a global define with more information:

#include <iostream>
#include <ctime>
#include <iomanip>

#define __FILENAME__ (__builtin_strrchr(__FILE__, '/') ? __builtin_strrchr(__FILE__, '/') + 1 : __FILE__)    // only show filename and not it's path (less clutter)
#define INFO std::cout << std::put_time(std::localtime(&time_now), "%y-%m-%d %OH:%OM:%OS") << " [INFO] " << __FILENAME__ << "(" << __FUNCTION__ << ":" << __LINE__ << ") >> "
#define ERROR std::cout << std::put_time(std::localtime(&time_now), "%y-%m-%d %OH:%OM:%OS") << " [ERROR] " << __FILENAME__ << "(" << __FUNCTION__ << ":" << __LINE__ << ") >> "

static std::time_t time_now = std::time(nullptr);

Use it like this:

INFO << "Hello world" << std::endl;
ERROR << "Goodbye world" << std::endl;

Sample output:

16-06-23 21:33:19 [INFO] main.cpp(main:6) >> Hello world
16-06-23 21:33:19 [ERROR] main.cpp(main:7) >> Goodbye world

Put these lines in your header file. I find this very useful for debugging, etc.

Might I suggest WinSnap http://www.ntwind.com/software/winsnap/download-free-version.html. It provides an autosave option and capture the alt+printscreen and other key combinations to capture screen, windows, dialog, etc.

Instead of this goto mess, try using the ampersand & or double ampersand && (conditional to errorlevel 0) as command separators.

I fixed a script snippet with this trick, to summarize, I have three batch files, one which calls the other two after having found which letters the external backup drives have been assigned. I leave the first file on the primary external drive so the calls to its backup routine worked fine, but the calls to the second one required an active drive change. The code below shows how I fixed it:

for %%b in (d e f g h i j k l m n o p q r s t u v w x y z) DO (
if exist "%%b:\Backup.cmd" %%b: & CALL "%%b:\Backup.cmd"
)

Code

train["label_Name"].value_counts().to_frame()

where : label_Name Mean column_name

result (my case) :-

0    29720 
1     2242 
Name: label, dtype: int64

I would recommend 422. It's not part of the main HTTP spec, but it is defined by a public standard (WebDAV) and it should be treated by browsers the same as any other 4xx status code.

From RFC 4918:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

ftp4j is the best one, both for features and license:

Bootstrap 4 solution

bootstrap 4 ships built-in toggle. Here is the documentation. https://getbootstrap.com/docs/4.3/components/forms/#switches

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

You need to configure Apache (the webserver) to process PHP scripts as PHP. Check Apache's configuration. You need to load the module (the path may differ on your system):

LoadModule php5_module "c:/php/php5apache.dll"

And you also need to tell Apache what to process with PHP:

AddType application/x-httpd-php .php

See the documentation for more details.

As Tmdean correctly pointed out you can use the Mid() function. The MSDN Library also has a great reference section on VBScript which you can find here:

VBScript Language Reference (MSDN Library)

I did this:

git ls-files | xargs file | grep "ASCII" | cut -d : -f 1 | xargs wc -l

this works if you count all text files in the repository as the files of interest. If some are considered documentation, etc, an exclusion filter can be added.

Just a note for @"John Sansom" answer,

If the foreign key dependencies are sought, I think that the PT Where clause should be:

i1.CONSTRAINT_TYPE = 'FOREIGN KEY'  -- instead of 'PRIMARY KEY'

and its the ON condition:

ON PT.TABLE_NAME = FK.TABLE_NAME – instead of PK.TABLE_NAME

As commonly is used the primary key of the foreign table, I think this issue has not been noticed before.

Just add the directory on the command line:

svn checkout svn://192.168.1.1/projectname/ target-directory/

Not gonna happen with CSS only

Inline javascript

<a href='index.html' 
    onmouseover='this.style.textDecoration="none"' 
    onmouseout='this.style.textDecoration="underline"'>
    Click Me
</a>

In a working draft of the CSS2 spec it was declared that you could use pseudo-classes inline like this:

<a href="http://www.w3.org/Style/CSS"
   style="{color: blue; background: white}  /* a+=0 b+=0 c+=0 */
      :visited {color: green}           /* a+=0 b+=1 c+=0 */
      :hover {background: yellow}       /* a+=0 b+=1 c+=0 */
      :visited:hover {color: purple}    /* a+=0 b+=2 c+=0 */
     ">
</a>

but it was never implemented in the release of the spec as far as I know.

I found a working answer that allow to override the checked Intranet Compatibility View. Just add in the OnInit event of your page this line (no meta or web.config customHeader need):

The easiest way is to use mysql_result. I copied some of the code below from other answers to save time.

$link = mysql_connect('localhost','root','yourPassword')
mysql_select_db('database',$link);
$sql = 'SELECT id FROM games'
$result = mysql_query($sql,$link);

$num_rows = mysql_num_rows($result);

// i is the row number and will be 0 through $num_rows-1
for ($i = 0; $i < $num_rows; $i++) {
    $value = mysql_result($result, i, 'id');
    echo 'Row ', i, ': ', $value, "\n";
}

Be sure you have C++ Redistributable for Visual Studio 2015 RC. Try to download the last version:

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

An array that contains a property that equals to

yourArray.contains(where: {$0.propertyToCheck == value })

Returns boolean.

As others have mentioned, you can't extract the type of a variable at runtime. However, you could construct your own "object" and store the type along with it. Then you would be able to check it at runtime:

typedef struct {
   int  type;     // or this could be an enumeration
   union {
      double d;
      int i;
   } u;
} CheesyObject;

Then set the type as needed in the code:

CheesyObject o;
o.type = 1;  // or better as some define, enum value...
o.u.d = 3.14159;

plt.axis('scaled')

works well for me.

that is happening with me in XML; I just Change application/XML to be text/XML which solve my Problem

Class.getSimpleName()

Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

It is actually stripping the package information from the name, but this is hidden from you.

I had a similar issue and had to do the following to the pool.d/www.conf file

php_admin_value[error_log] = /var/log/fpm-php.www.log
php_admin_flag[log_errors] = on

It still wasn't writing the log file so I actually had to create it by touch /var/log/fpm-php.www.log then setting the correct owner sudo chown www-data:www-data /var/log/fpm-php.www.log.

Once this was done, and php5-fpm restarted, logging was resumed.

I know this is old but you could create a custom extension if you needed to create that form over and over:

public static MvcForm BeginMultipartForm(this HtmlHelper htmlHelper)
{
    return htmlHelper.BeginForm(null, null, FormMethod.Post, 
     new Dictionary<string, object>() { { "enctype", "multipart/form-data" } });
}

Usage then just becomes

<% using(Html.BeginMultipartForm()) { %>

You're applying transitions only to the :hover pseudo-class, and not to the element itself.

.item {   
  height:200px;
  width:200px;
  background:red; 
  -webkit-transition: opacity 1s ease-in-out;
  -moz-transition: opacity 1s ease-in-out;
  -ms-transition: opacity 1s ease-in-out;
  -o-transition: opacity 1s ease-in-out;
  transition: opacity 1s ease-in-out;
}

.item:hover {
  zoom: 1;
  filter: alpha(opacity=50);
  opacity: 0.5;
}

Demo: http://jsfiddle.net/7uR8z/6/

If you don't want the transition to affect the mouse-over event, but only mouse-out, you can turn transitions off for the :hover state :

.item:hover {
  -webkit-transition: none;
  -moz-transition: none;
  -ms-transition: none;
  -o-transition: none;
  transition: none;
  zoom: 1;
  filter: alpha(opacity=50);
  opacity: 0.5;
}

Demo: http://jsfiddle.net/7uR8z/3/

You can try adding event handler from design like this: Open form in design view, open properties window or press F4, click event toolbar button to view events on Form object, find FormClosing event in Behavior group, and double click it.

Short tags are coming back thanks to Zend Framework pushing the "PHP as a template language" in their default MVC configuration. I don't see what the debate is about, most of the software you will produce during your lifetime will operate on a server you or your company will control. As long as you keep yourself consistent, there shouldn't be any problems.

UPDATE

After doing quite a bit of work with Magento, which uses long form. As a result, I've switched to the long form of:

<?php and <?php echo

over

<? and <?=

Seems like a small amount of work to assure interoperability.

Don't use SSL on port 465, it's been deprecated since 1998 and is only used by Microsoft products that didn't get the memo; use TLS on port 587 instead: So, the code below should work very well for you.

mail->IsSMTP(); // telling the class to use SMTP
$mail->Host       = "smtp.gmail.com"; // SMTP server

$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->SMTPSecure = "tls";                 // sets the prefix to the servier
$mail->Host       = "smtp.gmail.com";      // sets GMAIL as the SMTP server
$mail->Port       = 587;                   // set the SMTP port for the 

If you want beautiful and responsive alert dialog then you can use flutter packages like

rflutter alert ,fancy dialog,rich alert,sweet alert dialogs,easy dialog & easy alert

These alerts are good looking and responsive. Among them rflutter alert is the best. currently I am using rflutter alert for my apps.

1) Create a .gitignore file. To do that, you just create a .txt file and change the extension as follows:

Then you have to change the name, writing the following line in a cmd window:

 rename git.txt .gitignore

Where git.txt is the name of the file you've just created.

Then you can open the file and write all the files you don’t want to add on the repository. For example, mine looks like this:

#OS junk files
[Tt]humbs.db
*.DS_Store

#Visual Studio files
*.[Oo]bj
*.user
*.aps
*.pch
*.vspscc
*.vssscc
*_i.c
*_p.c
*.ncb
*.suo
*.tlb
*.tlh
*.bak
*.[Cc]ache
*.ilk
*.log
*.lib
*.sbr
*.sdf
*.pyc
*.xml
ipch/
obj/
[Bb]in
[Dd]ebug*/
[Rr]elease*/
Ankh.NoLoad

#Tooling
_ReSharper*/
*.resharper
[Tt]est[Rr]esult*

#Project files
[Bb]uild/

#Subversion files
.svn

# Office Temp Files
~$*

Once you have this, you need to add it to your Git repository. You have to save the file where your repository is.

Then in Git Bash you have to write the following line:

git config --global core.excludesfile ~/.gitignore_global

If the repository already exists then you have to do the following:

1. git rm -r --cached .
2. git add .
3. git commit -m ".gitignore is now working"

If the step 2 doesn’t work then you should write the whole route of the files that you would like to add.

I have tried many codes and finally, this worked for me in Swift 3.0 Latest [March 2017]

The ViewController class should be inherited the UITextFieldDelegate for making this code working.

class ViewController: UIViewController,UITextFieldDelegate  

Add the Text field with the Proper Tag number and this tag number is used to take the control to appropriate text field based on incremental tag number assigned to it.

override func viewDidLoad() {
    userNameTextField.delegate = self
    userNameTextField.tag = 0
    userNameTextField.returnKeyType = UIReturnKeyType.next
    passwordTextField.delegate = self
    passwordTextField.tag = 1
    passwordTextField.returnKeyType = UIReturnKeyType.go
}

In the above code, the returnKeyType = UIReturnKeyType.next where will make the Key pad return key to display as Next you also have other options as Join/Go etc, based on your application change the values.

This textFieldShouldReturn is a method of UITextFieldDelegate controlled and here we have next field selection based on the Tag value incrementation

func textFieldShouldReturn(_ textField: UITextField) -> Bool {
    if let nextField = textField.superview?.viewWithTag(textField.tag + 1) as? UITextField {
        nextField.becomeFirstResponder()
    } else {
        textField.resignFirstResponder()
        return true;
    }
    return false
 }

Try something like:-

ALTER TABLE table_name ADD  CONSTRAINT [DF_table_name_Created] 
DEFAULT (getdate()) FOR [created_at];

replacing table_name with the name of your table.

There is a hacky way to do it.

Set some boolean field to indicate whether the work was completed. Then before the block of code, set a timer to run a piece of code after your timeout. The timer will check if the block of code had finished executing, and if not, throw an exception. Otherwise it will do nothing.

The end of the block of code should, of course, set the field to true to indicate the work was done.

Just wanted to add my 2 cent, as the most answers relate to foreach-loop. Please, take a look at the following code:

Dictionary<String, Double> myProductPrices = new Dictionary<String, Double>();

//Add some entries to the dictionary

myProductPrices.ToList().ForEach(kvP => 
{
    kvP.Value *= 1.15;
    Console.Writeline(String.Format("Product '{0}' has a new price: {1} $", kvp.Key, kvP.Value));
});

Altought this adds a additional call of '.ToList()', there might be a slight performance-improvement (as pointed out here foreach vs someList.Foreach(){}), espacially when working with large Dictionaries and running in parallel is no option / won't have an effect at all.

Also, please note that you wont be able to assign values to the 'Value' property inside a foreach-loop. On the other hand, you will be able to manipulate the 'Key' as well, possibly getting you into trouble at runtime.

When you just want to "read" Keys and Values, you might also use IEnumerable.Select().

var newProductPrices = myProductPrices.Select(kvp => new { Name = kvp.Key, Price = kvp.Value * 1.15 } );

JsonP only works with type: GET,

Two options... regardless of application type you can always invoke:

Assembly.GetExecutingAssembly().GetName().Version

If a Windows Forms application, you can always access via application if looking specifically for product version.

Application.ProductVersion

Using GetExecutingAssembly for an assembly reference is not always an option. As such, I personally find it useful to create a static helper class in projects where I may need to reference the underlying assembly or assembly version:

// A sample assembly reference class that would exist in the `Core` project.
public static class CoreAssembly
{
    public static readonly Assembly Reference = typeof(CoreAssembly).Assembly;
    public static readonly Version Version = Reference.GetName().Version;
}

Then I can cleanly reference CoreAssembly.Version in my code as required.

Three ways you can do this - from the form designer, select the form, and where you normally see the list of properties, just above it there should be a little lightning symbol - this shows you all the events of the form. Find the form load event in the list, and you should be able to pick ProgramViwer_Load from the dropdown.

A second way to do it is programmatically - somewhere (constructor maybe) you'd need to add it, something like: ProgramViwer.Load += new EventHandler(ProgramViwer_Load);

A third way using the designer (probably the quickest) - when you create a new form, double click on the middle of it on it in design mode. It'll create a Form load event for you, hook it in, and take you to the event handler code. Then you can just add your two lines and you're good to go!

Use Iterator.remove().

I would have added a comment (cant low rating)

Just to add on user276042 and pangratz

dat$x = as.numeric(as.character(dat$x))

This will override the values of existing column x

What you are asking is thoroughly covered by Eric Lippert in his blog post Closing over the loop variable considered harmful and its sequel.

For me, the most convincing argument is that having new variable in each iteration would be inconsistent with for(;;) style loop. Would you expect to have a new int i in each iteration of for (int i = 0; i < 10; i++)?

The most common problem with this behavior is making a closure over iteration variable and it has an easy workaround:

foreach (var s in strings)
{
    var s_for_closure = s;
    query = query.Where(i => i.Prop == s_for_closure); // access to modified closure

My blog post about this issue: Closure over foreach variable in C#.

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

I'll take the risk of stating the obvious: You call the function, if it's defined in the base class it's automatically available in the derived class (unless it's private).

If there is a function with the same signature in the derived class you can disambiguate it by adding the base class's name followed by two colons base_class::foo(...). You should note that unlike Java and C#, C++ does not have a keyword for "the base class" (super or base) since C++ supports multiple inheritance which may lead to ambiguity.

class left {
public:
    void foo();
};

class right {
public:
    void foo();
};

class bottom : public left, public right {
public:
    void foo()
    {
        //base::foo();// ambiguous
        left::foo();
        right::foo();

        // and when foo() is not called for 'this':
        bottom b;
        b.left::foo();  // calls b.foo() from 'left'
        b.right::foo();  // call b.foo() from 'right'
    }
};

Incidentally, you can't derive directly from the same class twice since there will be no way to refer to one of the base classes over the other.

class bottom : public left, public left { // Illegal
};

I fetch all items from dynamodb with the following query. It works fine. i create these function generic in zend framework and access these functions over the project.

        public function getQuerydata($tablename, $filterKey, $filterValue){
            return $this->getQuerydataWithOp($tablename, $filterKey, $filterValue, 'EQ');
        }

        public function getQuerydataWithOp($tablename, $filterKey, $filterValue, $compOperator){
        $result = $this->getClientdb()->query(array(
                'TableName'     => $tablename,
                'IndexName'     => $filterKey,
                'Select'        => 'ALL_ATTRIBUTES',
                'KeyConditions' => array(
                    $filterKey => array(
                        'AttributeValueList' => array(
                            array('S' => $filterValue)
                        ),
                'ComparisonOperator' => $compOperator
            )
            )
        ));
            return $result['Items'];
        }

       //Below i Access these functions and get data.
       $accountsimg = $this->getQuerydataWithPrimary('accounts', 'accountID',$msgdata[0]['accountID']['S']);

Darren Davies is partially correct in saying that you should use a salt - there are several issues with his claim that MD5 is insecure.

You've said that you have to insert the password using an Md5 hash, but that doesn't really tell us why. Is it because that's the format used when validatinb the password? Do you have control over the code which validates the password?

The thing about using a salt is that it avoids the problem where 2 users have the same password - they'll also have the same hash - not a desirable outcome. By using a diferent salt for each password then this does not arise (with very large volumes of data there is still a risk of collisions arising from 2 different passwords - but we'll ignore that for now).

So you can aither generate a random value for the salt and store that in the record too, or you could use some of the data you already hold - such as the username:

$query="INSERT INTO ptb_users (id,
        user_id,
        first_name,
        last_name,
        email )
        VALUES('NULL',
        'NULL',
        '".$firstname."',
        '".$lastname."',
        '".$email."',
        MD5('"$user_id.$password."')
        )";

(I am assuming that you've properly escaped all those strings earlier in your code)

For those who decided to use a structural directive as a replacement of *ngIf, keep in mind that the directive context isn't type checked by default. To create a type safe directive ngTemplateContextGuard property should be added, see Typing the directive's context. For example:

import { Directive, Input, TemplateRef, ViewContainerRef } from '@angular/core';

@Directive({
    // don't use 'ng' prefix since it's reserved for Angular
    selector: '[appVar]',
})
export class VarDirective<T = unknown> {
    // https://angular.io/guide/structural-directives#typing-the-directives-context
    static ngTemplateContextGuard<T>(dir: VarDirective<T>, ctx: any): ctx is Context<T> {
        return true;
    }

    private context?: Context<T>;

    constructor(
        private vcRef: ViewContainerRef,
        private templateRef: TemplateRef<Context<T>>
    ) {}

    @Input()
    set appVar(value: T) {
        if (this.context) {
            this.context.appVar = value;
        } else {
            this.context = { appVar: value };
            this.vcRef.createEmbeddedView(this.templateRef, this.context);
        }
    }
}

interface Context<T> {
    appVar: T;
}

The directive can be used just like *ngIf, except that it can store false values:

<ng-container *appVar="false as value">{{value}}</ng-container>

<!-- error: User doesn't have `nam` property-->
<ng-container *appVar="user as user">{{user.nam}}</ng-container>

<ng-container *appVar="user$ | async as user">{{user.name}}</ng-container>

The only drawback compared to *ngIf is that Angular Language Service cannot figure out the variable type so there is no code completion in templates. I hope it will be fixed soon.

You need to set the textbox to be multiline, this can be done two ways:

In the control:

<asp:TextBox runat="server" ID="MyBox" TextMode="MultiLine" Rows="10" />

Code Behind:

MyBox.TextMode = TextBoxMode.MultiLine;
MyBox.Rows = 10;

This will render as a <textarea>

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html

You can't. A redirect requires a webserver to accept the first request and send back the redirect. The "hosts" file just lets you set your own DNS records.

You probably need to reference it from the Rowsrather than as a cell:

var cellValue = dt.Rows[i][j];

As you have already stated in your question you have more than one option. A very basic approach would be using the tag referencing your PHP file in the method attribute. However as esoteric as it may sound AJAX is a more complete approach. Considering that an AJAX call (in combination with jQuery) can be as simple as:

$.post("yourfile.php", {data : "This can be as long as you want"});

And you get a more flexible solution, for example triggering a function after the server request is completed. Hope this helps.

To get last record details

1. Model::all()->last(); or
2. Model::orderBy('id', 'desc')->first();

To get last record id

1. Model::all()->last()->id; or
2. Model::orderBy('id', 'desc')->first()->id;

There's no one answer. The standard defines minimum ranges. An int must be able to hold at least 65535. Most modern compilers however allow ints to be 32-bit values. Additionally, there's nothing preventing multiple types from having the same capacity (e.g. int and long).

That being said, the standard does say in your particular case:

0 ? +18446744073709551615

as the range for unsigned long long int.

Further reading: http://en.wikipedia.org/wiki/C_variable_types_and_declarations#Size

declare @MyNumber int
set @MyNumber = 123
select 'My number is ' + CAST(@MyNumber as nvarchar(20))

In my case the issue was that the webserver was only sending the certificate and the intermediate CA, not the root CA. Adding this JVM option solved the problem: -Dcom.sun.security.enableAIAcaIssuers=true

Support for the caIssuers access method of the Authority Information Access extension is available. It is disabled by default for compatibility and can be enabled by setting the system property com.sun.security.enableAIAcaIssuers to the value true.

If set to true, Sun's PKIX implementation of CertPathBuilder uses the information in a certificate's AIA extension (in addition to CertStores that are specified) to find the issuing CA certificate, provided it is a URI of type ldap, http, or ftp.

Swift 3 version

extension UIView {
    enum ViewSide {
        case Top, Bottom, Left, Right
    }

    func addBorder(toSide side: ViewSide, withColor color: UIColor, andThickness thickness: CGFloat) {

        let border = CALayer()
        border.backgroundColor = color.cgColor

        switch side {
        case .Top:
            border.frame = CGRect(x: 0, y: 0, width: frame.size.width, height: thickness)
        case .Bottom:
            border.frame = CGRect(x: 0, y: frame.size.height - thickness, width: frame.size.width, height: thickness)
        case .Left:
            border.frame = CGRect(x: 0, y: 0, width: thickness, height: frame.size.height)
        case .Right:
            border.frame = CGRect(x: frame.size.width - thickness, y: 0, width: thickness, height: frame.size.height)
        }

        layer.addSublayer(border)
    }
}

In order to set corresponding border you should override viewDidLayoutSubviews() method:

override func viewDidLayoutSubviews() {
    super.viewDidLayoutSubviews()
    yourView.addBorder(toSide: UIView.ViewSide.Top, withColor: UIColor.lightGray, andThickness: 1)

This should work in MySql

SELECT * FROM 'my_table' WHERE 'month' = MONTH(CURRENT_TIMESTAMP) AND 'year' = YEAR(CURRENT_TIMESTAMP);

var findObjectByLabel = function(obj, label) 
{
  var foundLabel=null;
  if(obj.label === label)
  { 
    return obj; 
  }

for(var i in obj) 
{
    if(Array.isArray(obj[i])==true)
    {
        for(var j=0;j<obj[i].length;j++)
        {
            foundLabel = findObjectByLabel(obj[i], label);
        }
    }
    else if(typeof(obj[i])  == 'object')
    {
        if(obj.hasOwnProperty(i))
        {           
            foundLabel = findObjectByLabel(obj[i], label);     
        }       
    }

    if(foundLabel) 
    { 
        return foundLabel; 
    }

}

return null;
};

var x = findObjectByLabel(cars, "Sedan");
alert(JSON.stringify(x));

There are several way to approach globals:

1. Put your variables in a module.

Webpack evaluates modules only once, so your instance remains global and carries changes through from module to module. So if you create something like a globals.js and export an object of all your globals then you can import './globals' and read/write to these globals. You can import into one module, make changes to the object from a function and import into another module and read those changes in a function. Also remember the order things happen. Webpack will first take all the imports and load them up in order starting in your entry.js. Then it will execute entry.js. So where you read/write to globals is important. Is it from the root scope of a module or in a function called later?

config.js

export default {
    FOO: 'bar'
}

somefile.js

import CONFIG from './config.js'
console.log(`FOO: ${CONFIG.FOO}`)

Note: If you want the instance to be new each time, then use an ES6 class. Traditionally in JS you would capitalize classes (as opposed to the lowercase for objects) like
import FooBar from './foo-bar' // <-- Usage: myFooBar = new FooBar()

2. Webpack's ProvidePlugin

Here's how you can do it using Webpack's ProvidePlugin (which makes a module available as a variable in every module and only those modules where you actually use it). This is useful when you don't want to keep typing import Bar from 'foo' again and again. Or you can bring in a package like jQuery or lodash as global here (although you might take a look at Webpack's Externals).

Step 1) Create any module. For example, a global set of utilities would be handy:

utils.js

export function sayHello () {
  console.log('hello')
}

Step 2) Alias the module and add to ProvidePlugin:

webpack.config.js

var webpack = require("webpack");
var path = require("path");

// ...

module.exports = {

  // ...

  resolve: {
    extensions: ['', '.js'],
    alias: {
      'utils': path.resolve(__dirname, './utils')  // <-- When you build or restart dev-server, you'll get an error if the path to your utils.js file is incorrect.
    }
  },

  plugins: [

    // ...

    new webpack.ProvidePlugin({
      'utils': 'utils'
    })
  ]  

}

Now just call utils.sayHello() in any js file and it should work. Make sure you restart your dev-server if you are using that with Webpack.

Note: Don't forget to tell your linter about the global, so it won't complain. For example, see my answer for ESLint here.

3. Use Webpack's DefinePlugin

If you just want to use const with string values for your globals, then you can add this plugin to your list of Webpack plugins:

new webpack.DefinePlugin({
  PRODUCTION: JSON.stringify(true),
  VERSION: JSON.stringify("5fa3b9"),
  BROWSER_SUPPORTS_HTML5: true,
  TWO: "1+1",
  "typeof window": JSON.stringify("object")
})

Use it like:

console.log("Running App version " + VERSION);
if(!BROWSER_SUPPORTS_HTML5) require("html5shiv");

4. Use the global window object (or Node's global)

window.foo = 'bar'  // For SPA's, browser environment.
global.foo = 'bar'  // Webpack will automatically convert this to window if your project is targeted for web (default), read more here: https://webpack.js.org/configuration/node/

You'll see this commonly used for polyfills, for example: window.Promise = Bluebird

5. Use a package like dotenv

(For server side projects) The dotenv package will take a local configuration file (which you could add to your .gitignore if there are any keys/credentials) and adds your configuration variables to Node's process.env object.

// As early as possible in your application, require and configure dotenv.    
require('dotenv').config()

Create a .env file in the root directory of your project. Add environment-specific variables on new lines in the form of NAME=VALUE. For example:

DB_HOST=localhost
DB_USER=root
DB_PASS=s1mpl3

That's it.

process.env now has the keys and values you defined in your .env file.

var db = require('db')
db.connect({
  host: process.env.DB_HOST,
  username: process.env.DB_USER,
  password: process.env.DB_PASS
})

Notes:

Regarding Webpack's Externals, use it if you want to exclude some modules from being included in your built bundle. Webpack will make the module globally available but won't put it in your bundle. This is handy for big libraries like jQuery (because tree shaking external packages doesn't work in Webpack) where you have these loaded on your page already in separate script tags (perhaps from a CDN).

For the Javadoc tag @see, you don't need to use @link; Javadoc will create a link for you. Try

@see com.my.package.Class#method()

Here's more info about @see.

It is important that you decorate the router link and link with square brackets as follows:

<a [routerLink]="['/service']"> <button class="btn btn-info"> link to other page </button></a>

Where "/service" in this case is the path url specified in the routing component.

function splitText(value, index) {
  if (value.length < index) {return value;} 
  return [value.substring(0, index)].concat(splitText(value.substring(index), index));
}
console.log(splitText('this is a testing peace of text',10));
// ["this is a ", "testing pe", "ace of tex", "t"] 

For those who want to split a text into array using the index.

I have found the browser referer implementation to be really inconsistent.

For example, an anchor element with the "download" attribute works as expected in Safari and sends the referer, but in Chrome the referer will be empty or "-" in the web server logs.

<a href="http://foo.com/foo" download="bar">click to download</a>

Is broken in Chrome - no referer sent.

I used the answer from Paul Pladijs since now. I found out, you can do a "normal" merge, conflicts occur, so you do

git checkout --theirs <file>

to resolve the conflict by using the revision from the other branch. If you do this for each file, you have the same behaviour as you would expect from

git merge <branch> -s theirs

Anyway, the effort is more than it would be with the merge-strategy! (This was tested with git version 1.8.0)

This attribute helps to get the best knowledge of the activity associated with your layout. This is also useful when you have to add onClick handlers on a view using QuickFix.

tools:context=".MainActivity"

TL;DR

You want this:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Mappings

The YAML equivalent of a JSON object is a mapping, which looks like these:

# flow style
{ foo: 1, bar: 2 }

# block style
foo: 1
bar: 2

Note that the first characters of the keys in a block mapping must be in the same column. To demonstrate:

# OK
   foo: 1
   bar: 2

# Parse error
   foo: 1
    bar: 2

Sequences

The equivalent of a JSON array in YAML is a sequence, which looks like either of these (which are equivalent):

# flow style
[ foo bar, baz ]

# block style
- foo bar
- baz

In a block sequence the -s must be in the same column.

JSON to YAML

Let's turn your JSON into YAML. Here's your JSON:

{"AAPL": [
  {
    "shares": -75.088,
    "date": "11/27/2015"
  },
  {
    "shares": 75.088,
    "date": "11/26/2015"
  },
]}

As a point of trivia, YAML is a superset of JSON, so the above is already valid YAML—but let's actually use YAML's features to make this prettier.

Starting from the inside out, we have objects that look like this:

{
  "shares": -75.088,
  "date": "11/27/2015"
}

The equivalent YAML mapping is:

shares: -75.088
date: 11/27/2015

We have two of these in an array (sequence):

- shares: -75.088
  date: 11/27/2015
- shares: 75.088
  date: 11/26/2015

Note how the -s line up and the first characters of the mapping keys line up.

Finally, this sequence is itself a value in a mapping with the key AAPL:

AAPL:
  - shares: -75.088
    date: 11/27/2015
  - shares: 75.088
    date: 11/26/2015

Parsing this and converting it back to JSON yields the expected result:

{
  "AAPL": [
    {
      "date": "11/27/2015", 
      "shares": -75.088
    }, 
    {
      "date": "11/26/2015", 
      "shares": 75.088
    }
  ]
}

You can see it (and edit it interactively) here.

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

Here is how I automatically start the MySQL service whenever the docker container runs.

On my case, I need to run not just MySQL but also PHP, Nginx and Memcached

I have the following lines in Dockerfile

RUN echo "daemon off;" >> /etc/nginx/nginx.conf
EXPOSE 80
EXPOSE 3306
CMD service mysql start && service php-fpm start && nginx -g 'daemon off;' && service memcached start && bash

Adding && bash would keep Nginx, MySQL, PHP and Memcached running within the container.

The problem might be in the rest of the html, the part that you didn't post.

With this example (I just closed the open tags):

<a class="item" ng-href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026" href="#/catalog/90d9650a36988e5d0136988f03ab000f/category/DATABASE_SERVERS/service/90cefc7a42b3d4df0142b52466810026">
<div class="col-lg-2 col-sm-3 col-xs-4 item-list-image">
<img ng-src="csa/images/library/Service_Design.png" src="csa/images/library/Service_Design.png">
</div>
<div class="col-lg-8 col-sm-9 col-xs-8">
<div class="col-xs-12">
    <p>
    <strong class="ng-binding">Smoke Sequential</strong>
    </p>
    </div>
</div>
</a>

I was able to find the element without trouble with:

driver.findElement(By.linkText("Smoke Sequential")).click();

If there is more text inside the element, you could try a find by partial link text:

driver.findElement(By.partialLinkText("Sequential")).click();

What you are trying to achieve should be done in the web browser because javascript simply doesn't work with html email design. The various email clients that are out there e.g. gmail, outlook, yahoo strip scripts put of the code for security reasons.

It is best to just use HTML and CSS to style your emails. Maybe you could have a call to action (cta) in your html email that sends the user to a web page with your expanding and collapsing content feature.

Regarding Johnathan Sampson's Linux example, watch out when you are doing an intval on the outcome of the "du" function, if the size is >2GB, it will keep showing 2GB.

Replace:

$totalSize = intval(fgets($io, 80));

by:

strtok(fgets($io, 80), " ");

supposed your "du" function returns the size separated with space followed by the directory/file name.

It is possible! Yes

In many cases, you might want to use XAMPP with a different PHP version than the one that comes preinstalled. You might do this to get the benefits of a newer version of PHP, or to reproduce bugs using an earlier version of PHP.

To use a different version of PHP with XAMPP, follow these steps:

1. Download a binary build of the PHP version that you wish to use from the PHP website, and extract the contents of the compressed archive file to your XAMPP installation directory (usually, C:\xampp). Ensure that you give it a different directory name to avoid overwriting the existing PHP version. For example, in this tutorial, we’ll call the new directory C:\xampp\php5-6-0. NOTE : Ensure that the PHP build you download matches the Apache build (VC9 or VC11) in your XAMPP platform.

2. Within the new directory, rename the php.ini-development file to php.ini. If you prefer to use production settings, you could instead rename the php.ini-production file to php.ini.

3. Edit the httpd-xampp.conf file in the apache\conf\extra\ subdirectory of your XAMPP installation directory. Within this file, search for all instances of the old PHP directory path and replace them with the path to the new PHP directory created in Step 1. In particular, be sure to change the lines

    LoadFile "/xampp/php/php5ts.dll"
    LoadFile "/xampp/php/libpq.dll"
    LoadModule php5_module "/xampp/php/php5apache2_4.dll"

to

    LoadFile "/xampp/php5-6-0/php5ts.dll"
    LoadFile "/xampp/php5-6-0/libpq.dll"
    LoadModule php5_module "/xampp/php5-6-0/php5apache2_4.dll"

NOTE : Remember to adjust the file and directory paths above to reflect valid paths on your system.

4. Restart your Apache server through the XAMPP control panel for your changes to take effect. The new version of PHP should now be active. To verify this, browse to the URL http://localhost/xampp/phpinfo.php, which displays the output of the phpinfo() command, and check the version number at the top of the page.

You may use this formula to get the path of the file:

=LEFT(CELL("filename"),FIND("[",CELL("filename"),1)-1)

using is for namespaces only - if both classes are in the same namespace just drop the using.

You have to reference the assembly created in the first step when you compile the .exe:

csc /t:library /out:MyClass.dll MyClass.cs
csc /reference:MyClass.dll /t:exe /out:MyProgram.exe MyMainClass.cs

You can make things simpler if you just compile the files together:

csc /t:exe /out:MyProgram.exe MyMainClass.cs MyClass.cs

or

csc /t:exe /out:MyProgram.exe *.cs

EDIT: Here's how the files should look like:

MyClass.cs:

namespace MyNamespace {
    public class MyClass {
        void stuff() {

        }
    }
}

MyMainClass.cs:

using System;

namespace MyNamespace {
    public class MyMainClass {
        static void Main() {
            MyClass test = new MyClass();
        }
    }
}

UPDATE: Since this answer was written, Visibility was introduced and provides the best solution to this problem.

You can use Opacity with an opacity: of 0.0 to draw make an element hidden but still occupy space.

To make it not occupy space, replace it with an empty Container().

EDIT: To wrap it in an Opacity object, do the following:

            new Opacity(opacity: 0.0, child: new Padding(
              padding: const EdgeInsets.only(
                left: 16.0,
              ),
              child: new Icon(pencil, color: CupertinoColors.activeBlue),
            ))

If you want the margin-left to work on a span element you'll need to make it display: inline-block or display:block as well.

Android N (Api level 24) update (no warnings):

   Locale getCurrentLocale(Context context){
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N){
            return context.getResources().getConfiguration().getLocales().get(0);
        } else{
            //noinspection deprecation
            return context.getResources().getConfiguration().locale;
        }
    }

It's

int color =  Color.parseColor("colorstring");

Nebojsa Tomcic's answer wasn't helpful for me. I have RelativeLayout with TextView and AutoCompleteTextView inside it. I need to scroll the TextView to the bottom when the keyboard is showed and when it's hidden. To accomplish this I overrode onLayout method and it works fine for me.

public class ExtendedLayout extends RelativeLayout
{
    public ExtendedLayout(Context context, AttributeSet attributeSet)
    {
        super(context, attributeSet);
        LayoutInflater inflater = (LayoutInflater)
                context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        inflater.inflate(R.layout.main, this);
    }

    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b)
    {
        super.onLayout(changed, l, t, r, b);

        if (changed)
        {
            int scrollEnd = (textView.getLineCount() - textView.getHeight() /
                textView.getLineHeight()) * textView.getLineHeight();
            textView.scrollTo(0, scrollEnd);
        }
    }
}

1. You have to replace \n with <br/> before inset into database.

   $data = str_replace("\n", "<br/>", $data);

   In this case in database table you will see <br/> instead of new line.

   e.g.

   First Line
Second Line

   will look like:

   First Line<br/>Second Line

2. Another way to view data with new line. First read data from database. And then replace \n with <br/> e.g. :

   echo $data;
$data = str_replace("\n", "<br/>", $data);
echo "<br/><br/>" . $data;

   output:

   First Line Second Line

First Line
Second Line

   
   You will find details about function str_replace() here: http://php.net/manual/en/function.str-replace.php

I was also having a similar problem. Finally found one solution at https://techmeals.com/fe/questions/htmlcss/4/How-to-customize-the-select-drop-down-in-css-which-works-for-all-the-browsers

Note:

1) For Firefox support there is special CSS handling for SELECT element's parent, please take a closer look.

2) Download the down.png from Down.png

What you can do, is open up a WebSocket connection when the page loads, optionally send data through the WebSocket identifying the current user, and check when that connection is closed on the server.

In my case, I was fetching data from database, changing some column values and updating it in database but for updating I was using the same save query which was violating primary key constraints i.e duplicate values for primary key, so I had written a separate query for updating the columns and it solved my problem..!

That's for align right. Try it:

select{
    text-align-last:right;
    padding-right: 29px;
    direction: rtl;
}

the browser support for the text-align-last attribute can be found here: https://www.w3schools.com/cssref/css3_pr_text-align-last.asp It looks like only Safari is still not supporting it.

Using .Equals is also a lot easier to read.

A script to allow easy greping of ps results:

#!/usr/bin/php -f <?php $process = $argv[1]; echo shell_exec("ps -ef | grep $process | grep -v grep"); exit(0);

You can also try -j%NUMBER_OF_PROCESSORS% as an argument it will use all your cores. Makes things super fast on my quad core.

You might consider this Open Source tool, matiri, https://github.com/AAFC-MBB/matiri which is a concurrent mysql backup script with metadata in Sqlite3. Features:

• Multi-Server: Multiple MySQL servers are supported whether they are co-located on the same or separate physical servers.
• Parallel: Each database on the server to be backed up is done separately, in parallel (concurrency settable: default: 3)
• Compressed: Each database backup compressed
• Checksummed: SHA256 of each compressed backup file stored and the archive of all files
• Archived: All database backups tar'ed together into single file
• Recorded: Backup information stored in Sqlite3 database

Full disclosure: original matiri author.

Always use

//Super Fast
$('#my_id').find('.my_class'); 

instead of

// Fast:
$('#my_id .my_class');

Have look at JQuery Performance Rules.

Also at Jquery Doc

The simple answer is that csv files should always be opened in binary mode whether for input or output, as otherwise on Windows there are problems with the line ending. Specifically on output the csv module will write \r\n (the standard CSV row terminator) and then (in text mode) the runtime will replace the \n by \r\n (the Windows standard line terminator) giving a result of \r\r\n.

Fiddling with the lineterminator is NOT the solution.

gcc 4.6 supports a new feature of deleted functions, where you can write

hdealt() = delete;

to disable the default constructor.

Here the compiler has obviously seen that a default constructor can not be generated, and =delete'd it for you.

var RegExp = (/^HTTP|HTTP|http(s)?:\/\/(www\.)?[A-Za-z0-9]+([\-\.]{1}[A-Za-z0-9]+)*\.[A-Za-z]{2,40}(:[0-9]{1,40})?(\/.*)?$/);

Use atof()

But this is deprecated, use this instead:

const char* flt = "4.0800";
float f;
sscanf(flt, "%f", &f);

http://www.cplusplus.com/reference/clibrary/cstdlib/atof/

atof() returns 0 for both failure and on conversion of 0.0, best to not use it.

I think we have multiple solutions here:

• instance of could be a solution.

Why? In Java every class is inherited from the Object class itself. So if you have a variable and you would like to know its type. You can use

• System.out.println(((Object)f).getClass().getName());

or

• Integer.class.isInstance(1985); // gives true

or

• isPrimitive()

  public static void main(String[] args) {
  
   ClassDemo classOne = new ClassDemo();
   Class classOneClass = classOne();
  
   int i = 5;
   Class iClass = int.class;
  
   // checking for primitive type
   boolean retval1 = classOneClass.isPrimitive();
   System.out.println("classOneClass is primitive type? = " + retval1);
  
   // checking for primitive type?
   boolean retval2 = iClass.isPrimitive();
   System.out.println("iClass is primitive type? = " + retval2);
  }
  

This going to give us:

1. FALSE
2. TRUE

Pure JS

you can attach a listener to keyUp event for the document.

Also, if you want to make sure, any other key is not pressed along with Esc key, you can use values of ctrlKey, altKey, and shifkey.

 document.addEventListener('keydown', (event) => {
        
        if (event.key === 'Escape') {
         //if esc key was not pressed in combination with ctrl or alt or shift
            const isNotCombinedKey = !(event.ctrlKey || event.altKey || event.shiftKey);
            if (isNotCombinedKey) {
                console.log('Escape key was pressed with out any group keys')
              
            }
        }
    });

HTTP is stateless connection protocol, that is, the server cannot differentiate between different connections of different users.

Hence comes cookie, once a client connects first time to a server, the server generates a new session id, which later will be sent to the client as cookie value. And from now on, this session id will identify that client connection, because within each HTTP request it will see the appropriate session id inside cookies.

Now for each session id, the server keeps some data structure, which enables him to store data specific to user, this data structure you can abstractly call session.

You could still use framework 4.0 but you have to include getawaiter for the classes:

MethodName(parameters).ConfigureAwait(false).GetAwaiter().GetResult();

I did as how moplin mentioned .But in my case service send the JWT in response headers ,as a value under the key "Authorization".

Authorization ?Bearer eyJhbGciOiJIUzUxMiJ9.eyJzdWIiOiJpbWFsIiwiZXhwIjoxNDk4OTIwOTEyfQ.dYEbf4x5TGr_kTtwywKPI2S-xYhsp5RIIBdOa_wl9soqaFkUUKfy73kaMAv_c-6cxTAqBwtskOfr-Gm3QI0gpQ

What I did was ,make a Global variable in postman as

key->jwt
value->blahblah

in login request->Tests Tab, add

postman.clearGlobalVariable("jwt");
postman.setGlobalVariable("jwt", postman.getResponseHeader("Authorization"));

in other requests select the Headers tab and give

key->Authorization

value->{{jwt}}

Try this:

HTML:

<input type="checkbox" value="FALSE" />

jQ:

$("input[type='checkbox']").on('change', function(){
  $(this).val(this.checked ? "TRUE" : "FALSE");
})

jsfiddle

Please bear in mind that unchecked checkbox will not be submitted in regular form, and you should use hidden filed in order to do it.

Padding is inside of a View.

Margin is outside of a View.

This difference may be relevant to background or size properties.

For me it worked using flexbox.

Add a css class around the parent div / element with :

.parent {
    display: flex;
}

and for the button use:

.button {
    justify-content: center;
}

You should use a parent div, otherwise the button doesn't 'know' what the middle of the page / element is.

I have done it something like below for sending my model class from the Second Activity to First Activity. I used LiveData to achieve this, with the help of answers from Rupesh and TheCodeFather.

Second Activity

public static MutableLiveData<AudioListModel> getLiveSong() {
        MutableLiveData<AudioListModel> result = new MutableLiveData<>();
        result.setValue(liveSong);
        return result;
    }

"liveSong" is AudioListModel declared globally

Call this method in the First Activity

PlayerActivity.getLiveSong().observe(this, new Observer<AudioListModel>() {
            @Override
            public void onChanged(AudioListModel audioListModel) {
                if (PlayerActivity.mediaPlayer != null && PlayerActivity.mediaPlayer.isPlaying()) {
                    Log.d("LiveSong--->Changes-->", audioListModel.getSongName());
                }
            }
        });

May this help for new explorers like me.

If you can already see the SQL being printed, that means you have the code below in your hibernate.cfg.xml:

iPad Media Queries (All generations - including iPad mini)

Thanks to Apple's work in creating a consistent experience for users, and easy time for developers, all 5 different iPads (iPads 1-5 and iPad mini) can be targeted with just one CSS media query. The next few lines of code should work perfect for a responsive design.

iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)  { /* STYLES GO HERE */}

iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) { /* STYLES GO HERE */}

iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) { /* STYLES GO HERE */ }

iPad 3 & 4 Media Queries

If you're looking to target only 3rd and 4th generation Retina iPads (or tablets with similar resolution) to add @2x graphics, or other features for the tablet's Retina display, use the following media queries.

Retina iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */ }

iPad 1 & 2 Media Queries

If you're looking to supply different graphics or choose different typography for the lower resolution iPad display, the media queries below will work like a charm in your responsive design!

iPad 1 & 2 in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (-webkit-min-device-pixel-ratio: 1){ /* STYLES GO HERE */}

iPad 1 & 2 in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 1)  { /* STYLES GO HERE */}

iPad 1 & 2 in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) 
and (-webkit-min-device-pixel-ratio: 1) { /* STYLES GO HERE */ }

This relies on widely available wget, present almost everywhere, even on Alpine Linux.

wget --server-response --spider --quiet "${url}" 2>&1 | awk 'NR==1{print $2}'

The explanations are as follow :

--quiet

Turn off Wget's output.

Source - wget man pages

--spider

[ ... ] it will not download the pages, just check that they are there. [ ... ]

Source - wget man pages

--server-response

Print the headers sent by HTTP servers and responses sent by FTP servers.

Source - wget man pages

What they don't say about --server-response is that those headers output are printed to standard error (sterr), thus the need to redirect to stdin.

The output sent to standard input, we can pipe it to awk to extract the HTTP status code. That code is :

• the second ($2) non-blank group of characters: {$2}
• on the very first line of the header: NR==1

And because we want to print it... {print $2}.

wget --server-response --spider --quiet "${url}" 2>&1 | awk 'NR==1{print $2}'

Your code was compiled with Java 8.

Either compile your code with an older JDK (compliance level) or run it on a Java 8 JRE.

Hope this helps...

Warning!

This answer is now outdated. DOM Level 4 introduced MutationObserver, providing an effective replacement for the deprecated mutation events. See this answer to another question for a better solution than the one presented here. Seriously. Don't poll the DOM every 100 milliseconds; it will waste CPU power and your users will hate you.

Since mutation events were deprecated in 2012, and you have no control over the inserted elements because they are added by someone else's code, your only option is to continuously check for them.

function checkDOMChange()
{
    // check for any new element being inserted here,
    // or a particular node being modified

    // call the function again after 100 milliseconds
    setTimeout( checkDOMChange, 100 );
}

Once this function is called, it will run every 100 milliseconds, which is 1/10 (one tenth) of a second. Unless you need real-time element observation, it should be enough.

Create key value pairs on the phpsh commandline like this:

php> $keyvalues = array();
php> $keyvalues['foo'] = "bar";
php> $keyvalues['pyramid'] = "power";
php> print_r($keyvalues);
Array
(
    [foo] => bar
    [pyramid] => power
)

Get the count of key value pairs:

php> echo count($offerarray);
2

Get the keys as an array:

php> echo implode(array_keys($offerarray));
foopyramid

In my case when downloading a template the font files were just empty files. Probably an issue with the download. Chrome gave this generic error about it. I thought at first the solution of changing from woff to font-woff solved it, but it only made Chrome ignore the fonts. My solution was finding the fonts one by one and downloading/replacing them.

The :before pseudo element isn't needed for the clearfix hack itself.

It's just an additional nice feature helping to prevent margin-collapsing of the first child element. Thus the top margin of an child block element of the "clearfixed" element is guaranteed to be positioned below the top border of the clearfixed element.

display:table is being used because display:block doesn't do the trick. Using display:block margins will collapse even with a :before element.

There is one caveat: if vertical-align:baseline is used in table cells with clearfixed <div> elements, Firefox won't align well. Then you might prefer using display:block despite loosing the anti-collapsing feature. In case of further interest read this article: Clearfix interfering with vertical-align.

I am providing an answer from my own blog. Hope this will help.

What will be output?

Following XML file named users.xml will be created.

<?xml version="1.0" encoding="UTF-8" standalone="no" ?> 
<users>
    <user uid="1">
        <firstname>Interview</firstname>
        <lastname>Bubble</lastname>
        <email>[email protected]</email>
    </user>
</users>

PROCEDURE

Basic steps, in order to create an XML File with a DOM Parser, are:

1. Create a DocumentBuilder instance.

2. Create a Document from the above DocumentBuilder.

3. Create the elements you want using the Element class and its appendChild method.

4. Create a new Transformer instance and a new DOMSource instance.

5. Create a new StreamResult to the output stream you want to use.

6. Use transform method to write the DOM object to the output stream.

SOURCE CODE:

package com.example.TestApp;

import java.io.File;
import java.io.IOException;
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;
import org.w3c.dom.Document;
import org.w3c.dom.Element;

public class CreateXMLFileJava {

 public static void main(String[] args) throws ParserConfigurationException, 
                                               IOException, 
                                               TransformerException
    {
     // 1.Create a DocumentBuilder instance
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dbuilder = dbFactory.newDocumentBuilder();

    // 2. Create a Document from the above DocumentBuilder.
    Document document = dbuilder.newDocument();

    // 3. Create the elements you want using the Element class and its appendChild method.   

   // root element
    Element users = document.createElement("users");
    document.appendChild(users);   

    // child element
    Element user = document.createElement("user");
    users.appendChild(user);  

    // Attribute of child element
    user.setAttribute("uid", "1");   

    // firstname Element
    Element firstName = document.createElement("firstName");
    firstName.appendChild(document.createTextNode("Interview"));
    user.appendChild(firstName);   

    // lastName element
    Element lastName = document.createElement("lastName");
    lastName.appendChild(document.createTextNode("Bubble"));
    user.appendChild(lastName);   

    // email element
    Element email = document.createElement("email");
    email.appendChild(document.createTextNode("[email protected]"));
    user.appendChild(email);   

    // write content into xml file   

    // 4. Create a new Transformer instance and a new DOMSource instance.
   TransformerFactory transformerFactory = TransformerFactory.newInstance();
   Transformer transformer = transformerFactory.newTransformer();
   DOMSource source = new DOMSource(document);

   // 5. Create a new StreamResult to the output stream you want to use.
   StreamResult result = new StreamResult(new File("/Users/admin/Desktop/users.xml"));
   // StreamResult result = new StreamResult(System.out); // to print on console

   // 6. Use transform method to write the DOM object to the output stream.
   transformer.transform(source, result);  

   System.out.println("File created successfully");
 }
}

OUTPUT:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<users>
  <user uid="1">
     <firstName>Interview</firstName>
     <lastName>Bubble</lastName>
     <email>[email protected]</email>
  </user>
</users>

If you know the name of the filters, you can do it in a line.

users = users.filter(obj => obj.name == filter.name && obj.address == filter.address)

try to use li can be more even

<ul>
 <li><a href="#one"  data-role="button" role="button">back</a></li>
 </ul>

I couldn't get PSL's answer working for me so I found all I have to do is set the div holding the modal content with style="display: table;". The modal content itself says how big it wants to be and the modal accommodates it.

I think this functionality should be implemented inside the docker build command (using a flag?), so that it avoids a lot of code duplication.

I used the same condition as the accepted answer inside a wrapper function called docker_build so that it does the necessary checks before calling the original docker build command.

# Usage: docker_build <...> (instead of docker build)

docker_build()
{
    local arguments=("$@")
    local index
    for (( index=0; index<$#; index++ )); do
        case ${arguments[index]} in
            --tag)
                local tag=${arguments[index+1]}
                if [[ ! -z $(docker images -q "${tag}" 2> /dev/null) ]]; then
                    echo "Image ${tag} already exists."
                    return
                fi
                ;;
        esac
    done
    command docker build "$@"
}

Disclaimer: This is not ready for production because it works only with space-separated arguments in long format i.e --tag hello-world:latest. Also, this just modifies the docker build command only, all other commands remain same. If anyone has improvements, please let me know.

I felt like sharing this snippet because the idea of wrapping-standard-commands-in-bash-functions, to avoid code repetition, seemed more elegant and scalable than writing wrapper statements.

In order to give spacing between views inside a listView please use padding on your inflate views.

You can use android:paddingBottom="(number)dp" && android:paddingTop="(number)dp" on your view or views you're inflate inside your listview.

The divider solution is just a fix, because some day, when you'll want to use a divider color (right now it's transparent) you will see that the divider line is been stretched.

You can also try Nullable(T) Properties:

DateTime UpdatedTime = _objHotelPackageOrder.UpdatedDate.HasValue 
    ? DateTime.Now : _objHotelPackageOrder.UpdatedDate.Value;

No prompt use:

dir /x

Procure o nome reduzido do diretório na linha do "Program Files (x86)"

27/08/2018  15:07    <DIR>          PROGRA~2     Program Files (x86)

Coloque a seguinte configuração em php.ini para a opção:

extension_dir="C:\PROGRA~2\path\to\php\ext"

Acredito que isso resolverá seu problema.

(Update) V5.1 & Hooks (Requires React >= 16.8)

You can use useHistory, useLocation and useRouteMatch in your component to get match, history and location .

const Child = () => {
  const location = useLocation();
  const history = useHistory();
  const match = useRouteMatch("write-the-url-you-want-to-match-here");

  return (
    <div>{location.pathname}</div>
  )
}

export default Child

(Update) V4 & V5

You can use withRouter HOC in order to inject match, history and location in your component props.

class Child extends React.Component {
  static propTypes = {
    match: PropTypes.object.isRequired,
    location: PropTypes.object.isRequired,
    history: PropTypes.object.isRequired
  }

  render() {
    const { match, location, history } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

(Update) V3

You can use withRouter HOC in order to inject router, params, location, routes in your component props.

class Child extends React.Component {

  render() {
    const { router, params, location, routes } = this.props

    return (
      <div>{location.pathname}</div>
    )
  }
}

export default withRouter(Child)

Original answer

If you don't want to use the props, you can use the context as described in React Router documentation

First, you have to set up your childContextTypes and getChildContext

class App extends React.Component{

  getChildContext() {
    return {
      location: this.props.location
    }
  }

  render() {
    return <Child/>;
  }
}

App.childContextTypes = {
    location: React.PropTypes.object
}

Then, you will be able to access to the location object in your child components using the context like this

class Child extends React.Component{

   render() {
     return (
       <div>{this.context.location.pathname}</div>
     )
   }

}

Child.contextTypes = {
    location: React.PropTypes.object
 }

Normally, when the user tabs from field to field in a form (in a browser that allows tabbing, not all browsers do) the order is the order the fields appear in the HTML code.

However, sometimes you want the tab order to flow a little differently. In that case, you can number the fields using TABINDEX. The tabs then flow in order from lowest TABINDEX to highest.

More info on this can be found here w3

another good illustration can be found here

If you want to ensure that your intent is handled only by an email app (and not other text messaging or social apps), then use the ACTION_SENDTO action and include the "mailto:" data scheme. For example:

public void composeEmail(String[] addresses, String subject) {
    Intent intent = new Intent(Intent.ACTION_SENDTO);
    intent.setData(Uri.parse("mailto:")); // only email apps should handle this
    intent.putExtra(Intent.EXTRA_EMAIL, addresses);
    intent.putExtra(Intent.EXTRA_SUBJECT, subject);
    if (intent.resolveActivity(getPackageManager()) != null) {
        startActivity(intent);
    }
}

I found this in https://developer.android.com/guide/components/intents-common.html#Email

This same issue happened to me when I had more than one API function in the module and tried to wrap each function with 2 decorators:

1. @app.route()
2. My custom @exception_handler decorator

I got this same exception because I tried to wrap more than one function with those two decorators:

@app.route("/path1")
@exception_handler
def func1():
    pass

@app.route("/path2")
@exception_handler
def func2():
    pass

Specifically, it is caused by trying to register a few functions with the name wrapper:

def exception_handler(func):
  def wrapper(*args, **kwargs):
    try:
        return func(*args, **kwargs)
    except Exception as e:
        error_code = getattr(e, "code", 500)
        logger.exception("Service exception: %s", e)
        r = dict_to_json({"message": e.message, "matches": e.message, "error_code": error_code})
        return Response(r, status=error_code, mimetype='application/json')
  return wrapper

Changing the name of the function solved it for me (wrapper.__name__ = func.__name__):

def exception_handler(func):
  def wrapper(*args, **kwargs):
    try:
        return func(*args, **kwargs)
    except Exception as e:
        error_code = getattr(e, "code", 500)
        logger.exception("Service exception: %s", e)
        r = dict_to_json({"message": e.message, "matches": e.message, "error_code": error_code})
        return Response(r, status=error_code, mimetype='application/json')
  # Renaming the function name:
  wrapper.__name__ = func.__name__
  return wrapper

Then, decorating more than one endpoint worked.

I use a Dictionary and because of the repetetiveness and possible missing keys, I quickly patched together a small method:

 private static string GetKey(IReadOnlyDictionary<string, string> dictValues, string keyValue)
 {
     return dictValues.ContainsKey(keyValue) ? dictValues[keyValue] : "";
 }

Calling it:

var entry = GetKey(dictList,"KeyValue1");

Gets the job done.

For anyone looking for a solution to this with also wanting to cycle the elements, below might work -

from collections import deque  

foo = ['A', 'B', 'C', 'D']

def prev_and_next(input_list):
    CURRENT = input_list
    PREV = deque(input_list)
    PREV.rotate(-1)
    PREV = list(PREV)
    NEXT = deque(input_list)
    NEXT.rotate(1)
    NEXT = list(NEXT)
    return zip(PREV, CURRENT, NEXT)

for previous_, current_, next_ in prev_and_next(foo):
    print(previous_, current_, next)

Well, if you don't want to do the work yourself (object elements aren't really all that hard), you could always use Mike Alsup's Media plugin: http://jquery.malsup.com/media/

You can achieve it using this single line code :

String numbers = text.substring(text.length() - 7, text.length());

But be sure to catch Exception if the input string length is less than 7.

You can replace 7 with any number say N, if you want to get last 'N' characters.

this is for classes

$('.nameofdiv').val('we are developers');

for ids

$('#nameofdiv').val('we are developers');

now if u have an iput in a form u can use

$("#form li.name input.name_val").val('we are awsome developers');

You can get this done without the need of an external library, e.g: within a button

<button 
  onClick={() =>  navigator.clipboard.writeText('Copy this text to clipboard')}
>
  Copy
</button>

for internet explorer 11 and older browsers you might need to change the code a bit here is an example:

<button 
  onClick={() =>  window.clipboardData.setData("Text", 'Copy this text to clipboard')}>
 Copy
</button>

Hope this helps.

As others have mentioned, there is no official Go construct for this. The closest I can imagine would be a function that returns a slice. In this way, you can guarantee that no one will manipulate the elements of the original slice (as it is "hard-coded" into the array).

I have shortened your slice to make it...shorter...:

func GetLetterGoodness() []float32 {
    return []float32 { .0817,.0149,.0278,.0425,.1270,.0223 }
}

$destroy can refer to 2 things: method and event

1. method - $scope.$destroy

.directive("colorTag", function(){
  return {
    restrict: "A",
    scope: {
      value: "=colorTag"
    },
    link: function (scope, element, attrs) {
      var colors = new App.Colors();
      element.css("background-color", stringToColor(scope.value));
      element.css("color", contrastColor(scope.value));

      // Destroy scope, because it's no longer needed.
      scope.$destroy();
    }
  };
})

2. event - $scope.$on("$destroy")

See @SunnyShah's answer.

These are 2 equivalent solutions:

(in the following code, you should substitute 'UTC' for zone and now() for timestamp)

1. timestamp AT TIME ZONE zone - SQL-standard-conforming
2. timezone(zone, timestamp) - arguably more readable

The function timezone(zone, timestamp) is equivalent to the SQL-conforming construct timestamp AT TIME ZONE zone.

Explanation:

• zone can be specified either as a text string (e.g., 'UTC') or as an interval (e.g., INTERVAL '-08:00') - here is a list of all available time zones
• timestamp can be any value of type timestamp
• now() returns a value of type timestamp (just what we need) with your database's default time zone attached (e.g. 2018-11-11T12:07:22.3+05:00).
• timezone('UTC', now()) turns our current time (of type timestamp with time zone) into the timezonless equivalent in UTC.
  E.g., SELECT timestamp with time zone '2020-03-16 15:00:00-05' AT TIME ZONE 'UTC' will return 2020-03-16T20:00:00Z.

Docs: timezone()

DSM's solution works, but if you wanted a direct equivalent to which you could do (df.columns == name).nonzero()

I also had this problem with implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'.

The solution for me was to go File -> Invalidate Caches / Restart -> Invalidate -> Close Project -> Remove project from project window -> Open Project (from project window).

With Dispatcher you will need to include

using System.Windows.Threading;

Also note that if you right-click DispatcherTimer and click Resolve it should add the appropriate references.

Maybe this will help someone...

From PictureDrawable to Bitmap, use:

private Bitmap pictureDrawableToBitmap(PictureDrawable pictureDrawable){ 
    Bitmap bmp = Bitmap.createBitmap(pictureDrawable.getIntrinsicWidth(), pictureDrawable.getIntrinsicHeight(), Config.ARGB_8888); 
    Canvas canvas = new Canvas(bmp); 
    canvas.drawPicture(pictureDrawable.getPicture()); 
    return bmp; 
}

... implemented as such:

Bitmap bmp = pictureDrawableToBitmap((PictureDrawable) drawable);

Here's a clue why an onchange() call might not fire your bound function:

http://jehiah.cz/archive/firing-javascript-events-properly

Try below code:

@Override
    public void onBackPressed() {
        Fragment myFragment = getSupportFragmentManager().findFragmentById(R.id.container);
        if (myFragment != null && myFragment instanceof StepOneFragment) {
            finish();
        } else {
            if (getSupportFragmentManager().getBackStackEntryCount() > 0) {
                getSupportFragmentManager().popBackStack();
            } else {
                super.onBackPressed();
            }
        }
    }

The Control+R mechanism is very useful :-) In either insert mode or command mode (i.e. on the : line when typing commands), continue with a numbered or named register:

• a - z the named registers
• " the unnamed register, containing the text of the last delete or yank
  
• % the current file name
  
• # the alternate file name
  
• * the clipboard contents (X11: primary selection)
  
• + the clipboard contents
  
• / the last search pattern
  
• : the last command-line
  
• . the last inserted text
  
• - the last small (less than a line) delete
  
• =5*5 insert 25 into text (mini-calculator)

See :help i_CTRL-R and :help c_CTRL-R for more details, and snoop around nearby for more CTRL-R goodness.

You'll need to learn how to use sed http://unixhelp.ed.ac.uk/CGI/man-cgi?sed

And also to use for so you can loop through your file entries http://www.cyberciti.biz/faq/bash-for-loop/

Your command will look something like this, I don't have a term beside me so I can't check

for i in `dir` do mv $i `echo $i | sed '/orig/new/g'`

What about using a tabular inside \author{}, just like in IEEE macros:

\documentclass{article}
\begin{document}
\title{Hello, World}
\author{
\begin{tabular}[t]{c@{\extracolsep{8em}}c} 
I. M. Author  & M. Y. Coauthor \\
My Department & Coauthor Department \\ 
My Institute & Coauthor Institute \\
email, address & email, address
\end{tabular}
}
\maketitle    
\end{document}

This will produce two columns authors with any documentclass.

Results:

The error is unrelated to PHP. It means you are somehow relying on Apache's mod_deflate, but that Apache module is not loaded. Try enabling mod_deflate in httpd.conf or commenting out the offending line (search for DEFLATE in httpd.conf).

As for the PHP curl extension, you must make sure it's activated in php.ini. Make sure extension_diris set to the directory php_curl.dll is in:

extension_dir = "C:/whatever" and then add

extension=php_curl.dll

for me the solution was:

rm -rf  ~/.node_gyp and
sudo npm install -g [email protected]
cd /usr/local/lib sudo ln -s ../../lib/libSystem.B.dylib libgcc_s.10.5.dylib 
brew install gcc
npm install

If you are using cygwin for git and trying to clone a git repository from a network drive you need to add the cygdrive path.

For example if you are cloning a git repo from z:/

$ git clone /cygdrive/z/[repo].git

As the others have said, there is no difference in the compiled code (IL) when you use either of the following:

var x1 = new object();
object x2 = new object;

I suppose Resharper warns you because it is [in my opinion] easier to read the first example than the second. Besides, what's the need to repeat the name of the type twice?

Consider the following and you'll get what I mean:

KeyValuePair<string, KeyValuePair<string, int>> y1 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

It's way easier to read this instead:

var y2 = new KeyValuePair<string, KeyValuePair<string, int>>("key", new KeyValuePair<string, int>("subkey", 5));

I like the simple solution using windows functions:

select t.*
from (select student.*, su.subname, max(mark) over (partition by subid) as maxmark
      from marks m join
           students st
           on m.stid = st.stid join
           subject su
           on m.subid = su.subid
     ) t
where t.mark = maxmark

Or, alternatively:

select t.*
from (select student.*, su.subname, rank(mark) over (partition by subid order by mark desc) as markseqnum
      from marks m join
           students st
           on m.stid = st.stid join
           subject su
           on m.subid = su.subid
     ) t
where markseqnum = 1

I have never used jekyll, but it's main page says that it uses Liquid, and according to their docs, I think the following should work:

<ul> {% for page in site.pages %}     {% if page.title != 'index' %}     <li><div class="drvce"><a href="{{ page.url }}">{{ page.title }}</a></div></li>     {% endif %} {% endfor %} </ul> 

The only way to control the size of stack within process is start a new Thread. But you can also control by creating a self-calling sub Java process with the -Xss parameter.

public class TT {
    private static int level = 0;

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

    public static void main(String[] args) throws InterruptedException {
        Thread t = new Thread(null, null, "TT", 1000000) {
            @Override
            public void run() {
                try {
                    level = 0;
                    System.out.println(fact(1 << 15));
                } catch (StackOverflowError e) {
                    System.err.println("true recursion level was " + level);
                    System.err.println("reported recursion level was "
                            + e.getStackTrace().length);
                }
            }

        };
        t.start();
        t.join();
        try {
            level = 0;

            System.err.println("reported recursion level was "
                    + e.getStackTrace().length);
        }
    }

These examples also work in bash no need to use sed:

#!/bin/bash
MYVAR=ho02123ware38384you443d34o3434ingtod38384day
MYVAR=${MYVAR//[a-zA-Z]/X} 
echo ${MYVAR//[0-9]/N}

you can also use the character class bracket expressions

#!/bin/bash
MYVAR=ho02123ware38384you443d34o3434ingtod38384day
MYVAR=${MYVAR//[[:alpha:]]/X} 
echo ${MYVAR//[[:digit:]]/N}

output

XXNNNNNXXXXNNNNNXXXNNNXNNXNNNNXXXXXXNNNNNXXX

What @Lanaru wanted to know however, if I understand the question correctly, is why the "full" or PCRE extensions \s\S\w\W\d\D etc don't work as supported in php ruby python etc. These extensions are from Perl-compatible regular expressions (PCRE) and may not be compatible with other forms of shell based regular expressions.

These don't work:

#!/bin/bash
hello=ho02123ware38384you443d34o3434ingtod38384day
echo ${hello//\d/}


#!/bin/bash
hello=ho02123ware38384you443d34o3434ingtod38384day
echo $hello | sed 's/\d//g'

output with all literal "d" characters removed

ho02123ware38384you44334o3434ingto38384ay

but the following does work as expected

#!/bin/bash
hello=ho02123ware38384you443d34o3434ingtod38384day
echo $hello | perl -pe 's/\d//g'

output

howareyoudoingtodday

Hope that clarifies things a bit more but if you are not confused yet why don't you try this on Mac OS X which has the REG_ENHANCED flag enabled:

#!/bin/bash
MYVAR=ho02123ware38384you443d34o3434ingtod38384day;
echo $MYVAR | grep -o -E '\d'

On most flavours of *nix you will only see the following output:

& is bitwise AND operator comparing bits of each operand.
For example,

int a = 4;
int b = 7;
System.out.println(a & b); // prints 4
//meaning in an 32 bit system
// 00000000 00000000 00000000 00000100
// 00000000 00000000 00000000 00000111
// ===================================
// 00000000 00000000 00000000 00000100

&& is logical AND operator comparing boolean values of operands only. It takes two operands indicating a boolean value and makes a lazy evaluation on them.

Here is a simple example for saving to a directory(external usb drive) using Python version 2.7.10 with Sublime Text 2 editor:

import numpy as np 
import matplotlib.pyplot as plt

X = np.linspace(-np.pi, np.pi, 256, endpoint = True)
C, S = np.cos(X), np.sin(X)

plt.plot(X, C, color = "blue", linewidth = 1.0, linestyle = "-")
plt.plot(X, S, color = "red", linewidth = 1.0, linestyle = "-")

plt.savefig("/Volumes/seagate/temp_swap/sin_cos_2.png", dpi = 72)

You can to do it this way:

string Camnr = "", Klantnr = "", ... // or String.Empty

Or you could declare them all first and then in the next line use your way.

@Esteban Küber is absolutely right.

Maybe one additional hint for bloody beginners like me. If you speciify the variables with %s, you have to follow this principle for EVERY input value, which means for the SET-variables as well as for the WHERE-variables.

Otherwise, you will have to face a termination message like 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '%s WHERE'

Maybe you can use pandas crosstab function

test5 = pd.crosstab(index=faultdf['Site Name'], columns=faultdf[''Abuse/NFF''])

test5.plot(kind='bar', stacked=True)

I think the best way is:

data: "{'Ids':['2','2']}"

To read this values Ids[0], Ids[1].

You need to use the various Bootstrap 4 centering methods...

• Use text-center for inline elements.
• Use justify-content-center for flexbox elements (ie; form-inline)

https://codeply.com/go/Am5LvvjTxC

Also, to offset the column, the col-sm-* must be contained within a .row, and the .row must be in a container...

<section id="cover">
    <div id="cover-caption">
        <div id="container" class="container">
            <div class="row">
                <div class="col-sm-10 offset-sm-1 text-center">
                    <h1 class="display-3">Welcome to Bootstrap 4</h1>
                    <div class="info-form">
                        <form action="" class="form-inline justify-content-center">
                            <div class="form-group">
                                <label class="sr-only">Name</label>

Your code should like this:

<span id="replies">8</span>

var currentValue = $("#replies").text();
var newValue = parseInt(parseFloat(currentValue)) + 1;
$("replies").text(newValue);

Hacks N Tricks

As of Jackson 2.0, @JsonSerialize(include = xxx) has been deprecated in favour of @JsonInclude

I have done this like this:

Load the font:

- (void)loadFont{
  // Get the path to our custom font and create a data provider.
  NSString *fontPath = [[NSBundle mainBundle] pathForResource:@"mycustomfont" ofType:@"ttf"]; 
  CGDataProviderRef fontDataProvider = CGDataProviderCreateWithFilename([fontPath UTF8String]);

  // Create the font with the data provider, then release the data provider.
  customFont = CGFontCreateWithDataProvider(fontDataProvider);
  CGDataProviderRelease(fontDataProvider); 
}

Now, in your drawRect:, do something like this:

-(void)drawRect:(CGRect)rect{
    [super drawRect:rect];
    // Get the context.
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextClearRect(context, rect);
    // Set the customFont to be the font used to draw.
    CGContextSetFont(context, customFont);

    // Set how the context draws the font, what color, how big.
    CGContextSetTextDrawingMode(context, kCGTextFillStroke);
    CGContextSetFillColorWithColor(context, self.fontColor.CGColor);
    UIColor * strokeColor = [UIColor blackColor];
    CGContextSetStrokeColorWithColor(context, strokeColor.CGColor);
    CGContextSetFontSize(context, 48.0f);

    // Create an array of Glyph's the size of text that will be drawn.
    CGGlyph textToPrint[[self.theText length]];

    // Loop through the entire length of the text.
    for (int i = 0; i < [self.theText length]; ++i) {
        // Store each letter in a Glyph and subtract the MagicNumber to get appropriate value.
        textToPrint[i] = [[self.theText uppercaseString] characterAtIndex:i] + 3 - 32;
    }
    CGAffineTransform textTransform = CGAffineTransformMake(1.0, 0.0, 0.0, -1.0, 0.0, 0.0);
    CGContextSetTextMatrix(context, textTransform);
    CGContextShowGlyphsAtPoint(context, 20, 50, textToPrint, [self.theText length]);
}

Basically you have to do some brute force looping through the text and futzing about with the magic number to find your offset (here, see me using 29) in the font, but it works.

Also, you have to make sure the font is legally embeddable. Most aren't and there are lawyers who specialize in this sort of thing, so be warned.

Just put

export HOME=/blah/whatever

at the point in the script where you want the change to happen. Since each process has its own set of environment variables, this definition will automatically cease to have any significance when the script terminates (and with it the instance of bash that has a changed environment).

I believe you forgot to include 'array'.

  typeOf : function(value) {
        var s = typeof value;
        if (s === 'object')
        {
            if (value)
            {
                if (typeof value.length === 'number' && !(value.propertyIsEnumerable('length')) && typeof value.splice === 'function')
                {
                    s = 'array';
                }
            }
            else
            {
                s = 'null';
            }
        }
        return s;
    },

From The Little MongoDB Book

Yet another alternative to using joins is to denormalize your data. Historically, denormalization was reserved for performance-sensitive code, or when data should be snapshotted (like in an audit log). However, with the ever- growing popularity of NoSQL, many of which don’t have joins, denormalization as part of normal modeling is becoming increasingly common. This doesn’t mean you should duplicate every piece of information in every document. However, rather than letting fear of duplicate data drive your design decisions, consider modeling your data based on what information belongs to what document.

So,

student
{ 
    _id: ObjectId(...),
    name: 'Jane',
    courses: [
    { 
        name: 'Biology 101', 
        mark: 85, 
        id:bio101 
    },
  ]
}

If its a RESTful API data, replace the course id with a GET link to the course resource

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Security;
using System.DirectoryServices.AccountManagement;

public struct Credentials
{
    public string Username;
    public string Password;
}

public class Domain_Authentication
{
    public Credentials Credentials;
    public string Domain;

    public Domain_Authentication(string Username, string Password, string SDomain)
    {
        Credentials.Username = Username;
        Credentials.Password = Password;
        Domain = SDomain;
    }

    public bool IsValid()
    {
        using (PrincipalContext pc = new PrincipalContext(ContextType.Domain, Domain))
        {
            // validate the credentials
            return pc.ValidateCredentials(Credentials.Username, Credentials.Password);
        }
    }
}

We don't stop or kill a thread rather we do Thread.currentThread().isInterrupted().

public class Task1 implements Runnable {
    public void run() {
            while (!Thread.currentThread().isInterrupted()) {
                       ................
                       ................
                       ................
                       ................
           }
    }
}

in main we will do like this:

Thread t1 = new Thread(new Task1());
t1.start();
t1.interrupt();

As of Rails 2.3.9, there is a setting in config/application.rb in which you can specify directories that contain files you want autoloaded.

From application.rb:

# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)

Try -

$('#chkdwn2').change(function(){
    if($(this).is(':checked'))
        $('#dropdown').removeAttr('disabled');
    else
        $('#dropdown').attr("disabled","disabled");
})

This will also work:

function str_lreplace($search, $replace, $subject)
{
    return preg_replace('~(.*)' . preg_quote($search, '~') . '(.*?)~', '$1' . $replace . '$2', $subject, 1);
}

UPDATE Slightly more concise version (http://ideone.com/B8i4o):

function str_lreplace($search, $replace, $subject)
{
    return preg_replace('~(.*)' . preg_quote($search, '~') . '~', '$1' . $replace, $subject, 1);
}

The Jquery .on works ok but I had some problems with the rendering implementing some of the solutions above. My problem using the .on is that somehow it was rendering the events differently than the .hover method.

Just fyi for anyone else that may also have the problem. I solved my problem by re-registering the hover event for the dynamically added item:

re-register the hover event because hover doesn't work for dynamically created items. so every time i create the new/dynamic item i add the hover code again. works perfectly

$('#someID div:last').hover(
    function() {
       //...
    },
    function() {
       //...
    }
);

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

$('#multiselect1').on('change', function(){
    var selected = $(this).find("option:selected");    
    var arrSelected = [];

    // selected.each(function(){
    //   arrSelected.push($(this).val());
    // });

    // The problem with the above selected.each statement is that  
    // there is no iteration value.
    // $(this).val() is all selected items, not an iterative item value.
    // With each iteration the selected items will be appended to 
    // arrSelected like so    
    //
    // arrSelected [0]['item0','item1','item2']
    // arrSelected [1]['item0','item1','item2'] 

    // You need to get the iteration value. 
    //
    selected.each((idx, val) => {
        arrSelected.push(val.value);
    });
    // arrSelected [0]['item0'] 
    // arrSelected [1]['item1']
    // arrSelected [2]['item2']
});

java.io.IOException in Netty means your game server tries to send data to a client, but that client has closed connection to your server.

And that exception is not the only one! There're several others. See BadClientSilencer in Xitrum. I had to add that to prevent those errors from messing my log file.

I was wondering, why they didnt provide in jquery itself, so i made a few changes in jquery file ,,, here are the changed code block:

original Code block:

    post: function( url, data, callback, type ) {
    // shift arguments if data argument was omited
    if ( jQuery.isFunction( data ) ) {
        type = type || callback;
        callback = data;
        data = {};
    }

    return jQuery.ajax({
        type: "POST",
        url: url,
        data: data,
        success: callback,
        dataType: type
    });  

Changed Code block:

        post: function (url, data, callback, failcallback, type) {
        if (type === undefined || type === null) {
            if (!jQuery.isFunction(failcallback)) { 
            type=failcallback
        }
        else if (!jQuery.isFunction(callback)) {
            type = callback
        }
        }
        if (jQuery.isFunction(data) && jQuery.isFunction(callback)) {
            failcallback = callback;

        }
        // shift arguments if data argument was omited
        if (jQuery.isFunction(data)) {
            type = type || callback;
            callback = data;
            data = {};

        }


        return jQuery.ajax({
            type: "POST",
            url: url,
            data: data,
            success: callback,
            error:failcallback,
            dataType: type
        });
    },

This should help the one trying to catch error on $.Post in jquery.

Updated: Or there is another way to do this is :

   $.post(url,{},function(res){
        //To do write if call is successful
   }).error(function(p1,p2,p3){
             //To do Write if call is failed
          });

<audio src="/music/good_enough.mp3" autoplay>
<p>If you are reading this, it is because your browser does not support the audio element.     </p>
<embed src="/music/good_enough.mp3" width="180" height="90" hidden="true" />
</audio>

Works for me just fine.

It's better practise, safer and more polite to detect if the process is running and tell the user to close it manually. Of course you could also add a timeout and kill the process if they've gone away...
