This is how I make forms full screen.

private void button1_Click(object sender, EventArgs e)
{
    int minx, miny, maxx, maxy;
    inx = miny = int.MaxValue;
    maxx = maxy = int.MinValue;

    foreach (Screen screen in Screen.AllScreens)
    {
        var bounds = screen.Bounds;
        minx = Math.Min(minx, bounds.X);
        miny = Math.Min(miny, bounds.Y);
        maxx = Math.Max(maxx, bounds.Right);
        maxy = Math.Max(maxy, bounds.Bottom);
    }

    Form3 fs = new Form3();
    fs.Activate();
    Rectangle tempRect = new Rectangle(1, 0, maxx, maxy);
    this.DesktopBounds = tempRect;
}

WPF only

don't have the exact code to hand, but in a recent project I think I used MouseDown event and simply put this:

frmBorderless.DragMove();

Window.DragMove Method (MSDN)

You need to set your window to be topmost.

You can define a a click function and then set the onclick attribute for the element.

function imageClick(url) {
    window.location = url;
}

<img src="../images/bottle.jpg" alt="bottle" class="thumbnails" onclick="imageClick('../images/bottle.html')" />

This approach lets you get rid of the surrounding <a> element. If you want to keep it, then define the onclick attribute on <a> instead of on <img>.

The KeyDown event only triggered at the standard TextBox or MaskedTextBox by "normal" input keys, not ENTER or TAB and so on.

One can get special keys like ENTER by overriding the IsInputKey method:

public class CustomTextBox : System.Windows.Forms.TextBox
{
    protected override bool IsInputKey(Keys keyData)
    {
        if (keyData == Keys.Return)
            return true;
        return base.IsInputKey(keyData);
    }
}

Then one can use the KeyDown event in the following way:

CustomTextBox ctb = new CustomTextBox();
ctb.KeyDown += new KeyEventHandler(tb_KeyDown);

private void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
          //Enter key is down

          //Capture the text
          if (sender is TextBox)
          {
              TextBox txb = (TextBox)sender;
              MessageBox.Show(txb.Text);
          }
    }
}

In Excel 2013 and resent versions, you can use F2 and F4 to speed things up when you want to toggle the lock.

About the keys:

• F2 - With a cell selected, it places the cell in formula edit mode.

• F4 - Toggles the cell reference lock (the $ signs).

• Example scenario with 'A4'.

  • Pressing F4 will convert 'A4' into '$A$4'
  • Pressing F4 again converts '$A$4' into 'A$4'
  • Pressing F4 again converts 'A$4' into '$A4'
  • Pressing F4 again converts '$A4' back to the original 'A4'

How To:

• In Excel, select a cell with a formula and hit F2 to enter formula edit mode. You can also perform these next steps directly in the Formula bar. (Issue with F2 ? Double check that 'F Lock' is on)

  • If the formula has one cell reference;
    • Hit F4 as needed and the single cell reference will toggle.
  • If the forumla has more than one cell reference, hitting F4 (without highlighting anything) will toggle the last cell reference in the formula.
  • If the formula has more than one cell reference and you want to change them all;
    • You can use your mouse to highlight the entire formula or you can use the following keyboard shortcuts;
    • Hit End key (If needed. Cursor is at end by default)
    • Hit Ctrl + Shift + Home keys to highlight the entire formula
    • Hit F4 as needed
  • If the formula has more than one cell reference and you only want to edit specific ones;
    • Highlight the specific values with your mouse or keyboard ( Shift and arrow keys) and then hit F4 as needed.

Notes:

• These notes are based on my observations while I was looking into this for one of my own projects.
• It only works on one cell formula at a time.
• Hitting F4 without selecting anything will update the locking on the last cell reference in the formula.
• Hitting F4 when you have mixed locking in the formula will convert everything to the same thing. Example two different cell references like '$A4' and 'A$4' will both become 'A4'. This is nice because it can prevent a lot of second guessing and cleanup.
• Ctrl+A does not work in the formula editor but you can hit the End key and then Ctrl + Shift + Home to highlight the entire formula. Hitting Home and then Ctrl + Shift + End.
• OS and Hardware manufactures have many different keyboard bindings for the Function (F Lock) keys so F2 and F4 may do different things. As an example, some users may have to hold down you 'F Lock' key on some laptops.
• 'DrStrangepork' commented about F4 actually closes Excel which can be true but it depends on what you last selected. Excel changes the behavior of F4 depending on the current state of Excel. If you have the cell selected and are in formula edit mode (F2), F4 will toggle cell reference locking as Alexandre had originally suggested. While playing with this, I've had F4 do at least 5 different things. I view F4 in Excel as an all purpose function key that behaves something like this; "As an Excel user, given my last action, automate or repeat logical next step for me".

I believe you are using the

echo Text >> Example.txt 

function?

If so the answer would be simply adding a "." (Dot) directly after the echo with nothing else there.

Example:

echo Blah
echo Blah 2
echo. #New line is added
echo Next Blah

I spent ages trying to figure this out but it is simple! You can use length(·). length(mylist) will tell you the number of objects mylist contains.

... and just realised someone had already answered this- sorry!

{ thetop : 10 } is a valid object literal. The code will create an object with a property named thetop that has a value of 10. Both the following are the same:

obj = { thetop : 10 };
obj = { "thetop" : 10 };

In ES5 and earlier, you cannot use a variable as a property name inside an object literal. Your only option is to do the following:

var thetop = "top";

// create the object literal
var aniArgs = {};

// Assign the variable property name with a value of 10
aniArgs[thetop] = 10; 

// Pass the resulting object to the animate method
<something>.stop().animate(
    aniArgs, 10  
);  

ES6 defines ComputedPropertyName as part of the grammar for object literals, which allows you to write the code like this:

var thetop = "top",
    obj = { [thetop]: 10 };

console.log(obj.top); // -> 10

You can use this new syntax in the latest versions of each mainstream browser.

Check it with a regex.

Javascript regexen don't have POSIX character classes, so you have to write character ranges manually:

if (!input_string.match(/^[0-9a-z]+$/))
  show_error_or_something()

Here ^ means beginning of string and $ means end of string, and [0-9a-z]+ means one or more of character from 0 to 9 OR from a to z.

More information on Javascript regexen here: https://developer.mozilla.org/en/JavaScript/Guide/Regular_Expressions

For Postgres

ALTER TABLE table_name ADD field_name serial PRIMARY KEY

Maybe the following extract from the Chapter 23 - Using the Criteria API to Create Queries of the Java EE 6 tutorial will throw some light (actually, I suggest reading the whole Chapter 23):

Querying Relationships Using Joins

For queries that navigate to related entity classes, the query must define a join to the related entity by calling one of the From.join methods on the query root object, or another join object. The join methods are similar to the JOIN keyword in JPQL.

The target of the join uses the Metamodel class of type EntityType<T> to specify the persistent field or property of the joined entity.

The join methods return an object of type Join<X, Y>, where X is the source entity and Y is the target of the join.

Example 23-10 Joining a Query

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> Pet_ = m.entity(Pet.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Pet, Owner> owner = pet.join(Pet_.owners);

Joins can be chained together to navigate to related entities of the target entity without having to create a Join<X, Y> instance for each join.

Example 23-11 Chaining Joins Together in a Query

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> Pet_ = m.entity(Pet.class);
EntityType<Owner> Owner_ = m.entity(Owner.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Owner, Address> address = cq.join(Pet_.owners).join(Owner_.addresses);

That being said, I have some additional remarks:

First, the following line in your code:

Root entity_ = cq.from(this.baseClass);

Makes me think that you somehow missed the Static Metamodel Classes part. Metamodel classes such as Pet_ in the quoted example are used to describe the meta information of a persistent class. They are typically generated using an annotation processor (canonical metamodel classes) or can be written by the developer (non-canonical metamodel). But your syntax looks weird, I think you are trying to mimic something that you missed.

Second, I really think you should forget this assay_id foreign key, you're on the wrong path here. You really need to start to think object and association, not tables and columns.

Third, I'm not really sure to understand what you mean exactly by adding a JOIN clause as generical as possible and what your object model looks like, since you didn't provide it (see previous point). It's thus just impossible to answer your question more precisely.

To sum up, I think you need to read a bit more about JPA 2.0 Criteria and Metamodel API and I warmly recommend the resources below as a starting point.

Are you sure you can't alter the HTML in the popup window?

If you can, add a <script> tag at the end of the popup's HTML, and call window.print() inside it. Then it won't be called until the HTML has loaded.

I found some useful information in a forum page, quoted below.
From this, mainly the sentences in bold formatting, my answer is:

• Make a bash (shell) script version of your .bat file (like other
  answers, with \ changed to / in file paths). For example:

  # File "example.command":
  #!/bin/bash
  java -cp  ".;./supportlibraries/Framework_Core.jar; ...etc.
  

• Then rename it to have the Mac OS file extension .command.
  That should make the script run using the Terminal app.

• If the app user is going to use a bash script version of the file on Linux
  or run it from the command line, they need to add executable rights
  (change mode bits) using this command, in the folder that has the file:

  chmod +rx [filename].sh
  #or:# chmod +rx [filename].command
  

The forum page question:

Good day, [...] I wondering if there are some "simple" rules to write an equivalent
of the Windows (DOS) bat file. I would like just to click on a file and let it run.

Info from some answers after the question:

Write a shell script, and give it the extension ".command". For example:

#!/bin/bash 
printf "Hello World\n" 

- Mar 23, 2010, Tony T1.

The DOS .BAT file was an attempt to bring to MS-DOS something like the idea of the UNIX script.
In general, UNIX permits you to make a text file with commands in it and run it by simply flagging
the text file as executable (rather than give it a specific suffix). This is how OS X does it.

However, OS X adds the feature that if you give the file the suffix .command, Finder
will run Terminal.app to execute it (similar to how BAT files work in Windows).

Unlike MS-DOS, however, UNIX (and OS X) permits you to specify what interpreter is used
for the script. An interpreter is a program that reads in text from a file and does something
with it. [...] In UNIX, you can specify which interpreter to use by making the first line in the
text file one that begins with "#!" followed by the path to the interpreter. For example [...]

#!/bin/sh
echo Hello World

- Mar 23, 2010, J D McIninch.

Also, info from an accepted answer for Equivalent of double-clickable .sh and .bat on Mac?:

On mac, there is a specific extension for executing shell
scripts by double clicking them: this is .command.

The use of -X [WHATEVER] merely changes the request's method string used in the HTTP request. This is easier to understand with two examples — one with -X [WHATEVER] and one without — and the associated HTTP request headers for each:

# curl -XPANTS -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.224.86.126) port 80 (#0)
> PANTS / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*

# curl -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.33.50.167) port 80 (#0)
> GET / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*

I really respect all the above answers. From my opinion Yes! For sure it is worth to use re.compile instead of compiling the regex, again and again, every time.

Using re.compile makes your code more dynamic, as you can call the already compiled regex, instead of compiling again and aagain. This thing benefits you in cases:

1. Processor Efforts
2. Time Complexity.
3. Makes regex Universal.(can be used in findall, search, match)
4. And makes your program looks cool.

Example :

  example_string = "The room number of her room is 26A7B."
  find_alpha_numeric_string = re.compile(r"\b\w+\b")

Using in Findall

 find_alpha_numeric_string.findall(example_string)

Using in search

  find_alpha_numeric_string.search(example_string)

Similarly you can use it for: Match and Substitute

Logs are set in your settings.py file. A new, default project, looks like this:

# A sample logging configuration. The only tangible logging
# performed by this configuration is to send an email to
# the site admins on every HTTP 500 error when DEBUG=False.
# See http://docs.djangoproject.com/en/dev/topics/logging for
# more details on how to customize your logging configuration.
LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'filters': {
        'require_debug_false': {
            '()': 'django.utils.log.RequireDebugFalse'
        }
    },
    'handlers': {
        'mail_admins': {
            'level': 'ERROR',
            'filters': ['require_debug_false'],
            'class': 'django.utils.log.AdminEmailHandler'
        }
    },
    'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
    }
}

By default, these don't create log files. If you want those, you need to add a filename parameter to your handlers

    'applogfile': {
        'level':'DEBUG',
        'class':'logging.handlers.RotatingFileHandler',
        'filename': os.path.join(DJANGO_ROOT, 'APPNAME.log'),
        'maxBytes': 1024*1024*15, # 15MB
        'backupCount': 10,
    },

This will set up a rotating log that can get 15 MB in size and keep 10 historical versions.

In the loggers section from above, you need to add applogfile to the handlers for your application

'loggers': {
        'django.request': {
            'handlers': ['mail_admins'],
            'level': 'ERROR',
            'propagate': True,
        },
        'APPNAME': {
            'handlers': ['applogfile',],
            'level': 'DEBUG',
        },
    }

This example will put your logs in your Django root in a file named APPNAME.log

Yes it is possible with the method:

- (void)setViewControllers:(NSArray *)viewControllers 
                 direction:(UIPageViewControllerNavigationDirection)direction 
                  animated:(BOOL)animated 
                completion:(void (^)(BOOL finished))completion;`

That is the same method used for setting up the first view controller on the page. Similar, you can use it to go to other pages.

Wonder why viewControllers is an array, and not a single view controller?

That's because a page view controller could have a "spine" (like in iBooks), displaying 2 pages of content at a time. If you display 1 page of content at a time, then just pass in a 1-element array.

An example in Swift:

pageContainer.setViewControllers([displayThisViewController], direction: .Forward, animated: true, completion: nil)

     class Program
    { 
         public static void Main()
        { 
            //To write in a txt file
             File.WriteAllText("C:\\Users\\HP\\Desktop\\c#file.txt", "Hello and Welcome");

           //To Read from a txt file & print on console
             string  copyTxt = File.ReadAllText("C:\\Users\\HP\\Desktop\\c#file.txt");
             Console.Out.WriteLine("{0}",copyTxt);
        }      
    }

In case people need a c++ solution, I put this OpenSSL solution together (for both encode and decode). You'll need to link with the "crypto" library (which is OpenSSL). This has been checked for leaks with valgrind (although you could add some additional error checking code to make it a bit better - I know at least the write function should check for return value).

#include <openssl/bio.h>
#include <openssl/evp.h>
#include <stdlib.h>

string base64_encode( const string &str ){

    BIO *base64_filter = BIO_new( BIO_f_base64() );
    BIO_set_flags( base64_filter, BIO_FLAGS_BASE64_NO_NL );

    BIO *bio = BIO_new( BIO_s_mem() );
    BIO_set_flags( bio, BIO_FLAGS_BASE64_NO_NL );

    bio = BIO_push( base64_filter, bio );

    BIO_write( bio, str.c_str(), str.length() );

    BIO_flush( bio );

    char *new_data;

    long bytes_written = BIO_get_mem_data( bio, &new_data );

    string result( new_data, bytes_written );
    BIO_free_all( bio );

    return result;

}



string base64_decode( const string &str ){

    BIO *bio, *base64_filter, *bio_out;
    char inbuf[512];
    int inlen;
    base64_filter = BIO_new( BIO_f_base64() );
    BIO_set_flags( base64_filter, BIO_FLAGS_BASE64_NO_NL );

    bio = BIO_new_mem_buf( (void*)str.c_str(), str.length() );

    bio = BIO_push( base64_filter, bio );

    bio_out = BIO_new( BIO_s_mem() );

    while( (inlen = BIO_read(bio, inbuf, 512)) > 0 ){
        BIO_write( bio_out, inbuf, inlen );
    }

    BIO_flush( bio_out );

    char *new_data;
    long bytes_written = BIO_get_mem_data( bio_out, &new_data );

    string result( new_data, bytes_written );

    BIO_free_all( bio );
    BIO_free_all( bio_out );

    return result;

}

We can use simple "date" input type, like below:

Birth date: <input type="date" name="userBirthDate" /><br />

Then we can link DateTime interface with built-in function 'explode':

public function validateDate()
    {
        $validateFlag = true;
        $convertBirthDate = DateTime::createFromFormat('Y-m-d', $this->birthDate);
        $birthDateErrors = DateTime::getLastErrors();

        if ($birthDateErrors['warning_count'] + $birthDateErrors['error_count'] > 0)
        {
            $_SESSION['wrongDateFormat'] = "The date format is wrong.";
        }

        else
        {
            $testBirthDate = explode('-', $this->birthDate);
            if ($testBirthDate[0] < 1900)
            {
                $validateFlag = false;
                $_SESSION['wrongDateYear'] = "We suspect that you did not born before XX century.";
            }
        }

        return $validateFlag;
    }

I tested it on Google Chrome and IE, everything works correctly. Furthemore, Chrome display simple additional interface. If you don't write anything in input or write it in bad format (correctly is following: '1919-12-23'), you will get the first statement. If you write everything in good format, but you type wrong date (I assumed that nobody could born before XX century), your controller will send the second statement.

You're trying to do &(2), &(4) which won't work

#romtest {
  .detailed {
    th {
      &:nth-child(2) {//your styles here}
      &:nth-child(4) {//your styles here}
      &:nth-child(6) {//your styles here}
      }
  }
}

Here is Swift 3 version of @oneway's answer for catching navigation bar back button event before it gets fired. As UINavigationBarDelegate cannot be used for UIViewController, you need to create a delegate that will be triggered when navigationBar shouldPop is called.

@objc public protocol BackButtonDelegate {
      @objc optional func navigationShouldPopOnBackButton() -> Bool 
}

extension UINavigationController: UINavigationBarDelegate  {

    public func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {

        if viewControllers.count < (navigationBar.items?.count)! {                
            return true
        }

        var shouldPop = true
        let vc = self.topViewController

        if vc.responds(to: #selector(vc.navigationShouldPopOnBackButton)) {
            shouldPop = vc.navigationShouldPopOnBackButton()
        }

        if shouldPop {
            DispatchQueue.main.async {
                self.popViewController(animated: true)
            }
        } else {
            for subView in navigationBar.subviews {
                if(0 < subView.alpha && subView.alpha < 1) {
                    UIView.animate(withDuration: 0.25, animations: {
                        subView.alpha = 1
                    })
                }
            }
        }

        return false
    }
}

And then, in your view controller add the delegate function:

class BaseVC: UIViewController, BackButtonDelegate {
    func navigationShouldPopOnBackButton() -> Bool {
        if ... {
            return true
        } else {
            return false
        }        
    }
}

I've realised that we often want to add an alert controller for users to decide whether they wanna go back. If so, you can always return false in navigationShouldPopOnBackButton() function and close your view controller by doing something like this:

func navigationShouldPopOnBackButton() -> Bool {
     let alert = UIAlertController(title: "Warning",
                                          message: "Do you want to quit?",
                                          preferredStyle: .alert)
            alert.addAction(UIAlertAction(title: "Yes", style: .default, handler: { UIAlertAction in self.yes()}))
            alert.addAction(UIAlertAction(title: "No", style: .cancel, handler: { UIAlertAction in self.no()}))
            present(alert, animated: true, completion: nil)
      return false
}

func yes() {
     print("yes")
     DispatchQueue.main.async {
            _ = self.navigationController?.popViewController(animated: true)
        }
}

func no() {
    print("no")       
}

ActiveX resolved in Chrome!
Hello all this is not the solution but the successful workaround and I have implemented as well.
This required some implementation on client machine as well that why is most suitable for intranet environment and not recommended for public sites. Even though one can implement it for public sites as well the only problem is end user has to download/implement solution.
Lets understand the key problem
Chrome cannot communicate with ActiceX
Solution: Since Chorme cannot communicate with ActiveX but still it can communicate with the API hosted on the client machine. So develop API using .Net MVC or any other technology so that through Ajax call it can communicate with the API and API communicate with the ActiveX object situated on the client machine. Since API also resides in Client machine that why there is no problem in communication. This API works as mediator between Chrome browser and ActiveX.
During API implementation you might encounter CORS issues, Use JSONP to deal with it.
Pictorial view of the solution

Other solution : Use URI Scheme like MailTo: or MS-Word to deal with outlook and word application. If your requirement is different then you can implement your customized URI Scheme.

Following your EDIT, here's my suggestion :

If you have only one entry, you might replace the Map by a dual object. Depending on the types, and your preferences:

• an array (of 2 values, key and value)
• a simple object with two properties

While searching about this problem, I found a recommendation that Page Visibility API should be used. Most modern browsers support this API according to Can I Use: http://caniuse.com/#feat=pagevisibility.

Here's a working example (derived from this snippet):

$(document).ready(function() {
  var hidden, visibilityState, visibilityChange;

  if (typeof document.hidden !== "undefined") {
    hidden = "hidden", visibilityChange = "visibilitychange", visibilityState = "visibilityState";
  } else if (typeof document.msHidden !== "undefined") {
    hidden = "msHidden", visibilityChange = "msvisibilitychange", visibilityState = "msVisibilityState";
  }

  var document_hidden = document[hidden];

  document.addEventListener(visibilityChange, function() {
    if(document_hidden != document[hidden]) {
      if(document[hidden]) {
        // Document hidden
      } else {
        // Document shown
      }

      document_hidden = document[hidden];
    }
  });
});

Update: The example above used to have prefixed properties for Gecko and WebKit browsers, but I removed that implementation because these browsers have been offering Page Visibility API without a prefix for a while now. I kept Microsoft specific prefix in order to stay compatible with IE10.

Use this code:

<div class="hidden"><li><a href="somehwere">Link text</a></li></div>

Try like below,

$('input[type=text]').val (function () {
    return this.value.toUpperCase();
})

You should use input[type=text] instead of :input or input as I believe your intention are to operate on textbox only.

You can get it from your local driver as below:

<dependency>
    <groupId>sample</groupId>
    <artifactId>com.sample</artifactId>
    <version>1.0</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/src/main/resources/yourJar.jar</systemPath>
</dependency>

No, according to Apple here:

Note: You cannot install apps from the App Store in simulation environments.

docker stop $(docker ps -a | grep "zalenium")
docker rm $(docker ps -a | grep "zalenium")

This should be enough.

UPDATE mytable SET spares = CONCAT(spares, ',', '818') WHERE id = 1

not working for me.

spares is NULL by default but its varchar

Python datetimes are a little clunky. Use arrow.

> str(arrow.utcnow())
'2014-05-17T01:18:47.944126+00:00'

Arrow has essentially the same api as datetime, but with timezones and some extra niceties that should be in the main library.

A format compatible with Javascript can be achieved by:

arrow.utcnow().isoformat().replace("+00:00", "Z")
'2018-11-30T02:46:40.714281Z'

Javascript Date.parse will quietly drop microseconds from the timestamp.

A C++ reference is not a pointer nor a Java/C# style reference and cannot be NULL. They behave as if they were an alias to another existing object.

In some cases, if there are bugs in your code, you might get a reference into an already dead or non-existent object, but the best thing you can do is hope that the program dies soon enough to be able to debug what happened and why your program got corrupted.

That is, I have seen code checking for 'null references' doing something like: if ( &reference == 0 ), but the standard is clear that there cannot be null references in a well-formed program. If a reference is bound to a null object the program is ill-formed and should be corrected. If you need optional values, use pointers (or some higher level construct like boost::optional), not references.

Sounds like an indexing problem, like Pabla Santa Cruz mentioned. Since your update is not conditional, you can DROP the column and RE-ADD it with a DEFAULT value.

You do not need to make an extra view for this, the functionality is already built in.

First each page with a login link needs to know the current path, and the easiest way is to add the request context preprosessor to settings.py (the 4 first are default), then the request object will be available in each request:

settings.py:

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.core.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.core.context_processors.request",
)

Then add in the template you want the Login link:

base.html:

<a href="{% url django.contrib.auth.views.login %}?next={{request.path}}">Login</a>

This will add a GET argument to the login page that points back to the current page.

The login template can then be as simple as this:

registration/login.html:

{% block content %}
<form method="post" action="">
  {{form.as_p}}
<input type="submit" value="Login">
</form>
{% endblock %}

Yes, you can put arrays in sessions, example:

$_SESSION['name_here'] = $your_array;

Now you can use the $_SESSION['name_here'] on any page you want but make sure that you put the session_start() line before using any session functions, so you code should look something like this:

 session_start();
 $_SESSION['name_here'] = $your_array;

Possible Example:

 session_start();
 $_SESSION['name_here'] = $_POST;

Now you can get field values on any page like this:

 echo $_SESSION['name_here']['field_name'];

As for the second part of your question, the session variables remain there unless you assign different array data:

 $_SESSION['name_here'] = $your_array;

Session life time is set into php.ini file.

Many of this question's numerous duplicates ask about the effects of floating point rounding on specific numbers. In practice, it is easier to get a feeling for how it works by looking at exact results of calculations of interest rather than by just reading about it. Some languages provide ways of doing that - such as converting a float or double to BigDecimal in Java.

Since this is a language-agnostic question, it needs language-agnostic tools, such as a Decimal to Floating-Point Converter.

Applying it to the numbers in the question, treated as doubles:

0.1 converts to 0.1000000000000000055511151231257827021181583404541015625,

0.2 converts to 0.200000000000000011102230246251565404236316680908203125,

0.3 converts to 0.299999999999999988897769753748434595763683319091796875, and

0.30000000000000004 converts to 0.3000000000000000444089209850062616169452667236328125.

Adding the first two numbers manually or in a decimal calculator such as Full Precision Calculator, shows the exact sum of the actual inputs is 0.3000000000000000166533453693773481063544750213623046875.

If it were rounded down to the equivalent of 0.3 the rounding error would be 0.0000000000000000277555756156289135105907917022705078125. Rounding up to the equivalent of 0.30000000000000004 also gives rounding error 0.0000000000000000277555756156289135105907917022705078125. The round-to-even tie breaker applies.

Returning to the floating point converter, the raw hexadecimal for 0.30000000000000004 is 3fd3333333333334, which ends in an even digit and therefore is the correct result.

We have set compatibility mode for IE11 to resolve an issue: Settings>Compatibility View Settings>Add your site name or Check "Display intranet sites in Compatibility View" if your portal is in the intranet.

Worked for us, hope this helps someone.

I think a nice solution is with the function filter of pandas and regex (match everything except "b"):

df.filter(regex="^(?!b$)")

Fixing Error code 1206: The number of locks exceeds the lock table size.

In my case, I work with MySQL Workbench (5.6.17) running on Windows with WampServer 2.5.

For Windows/WampServer you have to edit the my.ini file (not the my.cnf file)

To locate this file go to Menu Server/Server Status (in MySQL Workbench) and look under Server Directories/ Base Directory

In my.ini file there are defined sections for different settings, look for section [mysqld] (create it if it does not exist) and add the command: innodb_buffer_pool_size=4G

[mysqld]
innodb_buffer_pool_size=4G

The size of the buffer_pool file will depend on your specific machine, in most cases, 2G or 4G will fix the problem.

Remember to restart the server so it takes the new configuration, it corrected the problem for me.

Hope it helps!

You can really screw with his head and go for an IQueryable .foreach closure instead:

myList.ForEach(c => Console.WriteLine(c.ToString());

At first check out that your linked server is in the list by this query

select name from sys.servers

If it not exists then try to add to the linked server

EXEC sp_addlinkedserver @server = 'SERVER_NAME' --or may be server ip address

After that login to that linked server by

EXEC sp_addlinkedsrvlogin 'SERVER_NAME'
                         ,'false'
                         ,NULL
                         ,'USER_NAME'
                         ,'PASSWORD'

Then you can do whatever you want ,treat it like your local server

exec [SERVER_NAME].[DATABASE_NAME].dbo.SP_NAME @sample_parameter

Finally you can drop that server from linked server list by

sp_dropserver 'SERVER_NAME', 'droplogins'

If it will help you then please upvote.

Edit: Altered from the less-than-reliable checksum-only query I've discovered a way to do this (in SQL Server 2005) that works pretty well for me and I can use as many columns as I need (by adding them to the CHECKSUM() function). The REVERSE() function turns the ints into varchars to make the distinct more reliable

SELECT COUNT(DISTINCT (CHECKSUM(DocumentId,DocumentSessionId)) + CHECKSUM(REVERSE(DocumentId),REVERSE(DocumentSessionId)) )
FROM DocumentOutPutItems

I experienced this issue when trying to restore a database on MS SQL Server 2012.

Here's what worked for me:

I had to first run the RESTORE FILELISTONLY command below on the backup file to list the logical file names:

RESTORE FILELISTONLY 
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_backup.bak'

This displayed the LogicalName and the corresponding PhysicalName of the Data and Log files for the database respectively:

LogicalName      PhysicalName               
com.my_db        C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db.mdf
com.my_db_log    C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db_log.ldf

All I had to do was to simply replace the LogicalName and the corresponding PhysicalName of the Data and Log files for the database respectively in my database restore script:

USE master;
GO

ALTER DATABASE my_db SET SINGLE_USER WITH ROLLBACK IMMEDIATE;
GO

    
RESTORE DATABASE my_db
    FROM DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Backup\my_db_backup.bak'
    WITH REPLACE,
    MOVE 'com.my_db' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db.mdf',
    MOVE 'com.my_db_log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\DATA\com.my_db_log.ldf'
GO
    
ALTER DATABASE my_db SET MULTI_USER;
GO

And the Database Restore task ran successfully:

That's all.

I hope this helps

I created a jQuery version of PhpMyCoder's answer:

$('form').submit(function( e ) {    
    if(!($('#file')[0].files[0].size < 10485760 && get_extension($('#file').val()) == 'jpg')) { // 10 MB (this size is in bytes)
        //Prevent default and display error
        alert("File is wrong type or over 10Mb in size!");
        e.preventDefault();
    }
});

function get_extension(filename) {
    return filename.split('.').pop().toLowerCase();
}

There are also the %<% and %<=% comparison operators in the TeachingDemos package which allow you to do this like:

sum( 2 %<% x %<% 5 )
sum( 2 %<=% x %<=% 5 )

which gives the same results as:

sum( 2 < x & x < 5 )
sum( 2 <= x & x <= 5 )

Which is better is probably more a matter of personal preference.

ViewGroup class provides API for child views management in run-time, allowing to add/remove views as well.

Some other links on the subject:

Android, add new view without XML Layout

Android Runtime Layout Tutorial

http://developer.android.com/reference/android/view/View.html

http://developer.android.com/reference/android/widget/LinearLayout.html

You can do something like this:

<input onfocus="(this.type='date')" class="js-form-control" placeholder="Enter Date">

If you have the code to log_out(), rewrite it. Most likely, you can do:

static FILE *logfp = ...;

void log_out(const char *fmt, ...)
{
    va_list args;

    va_start(args, fmt);
    vfprintf(logfp, fmt, args);
    va_end(args);
}

If there is extra logging information needed, that can be printed before or after the message shown. This saves memory allocation and dubious buffer sizes and so on and so forth. You probably need to initialize logfp to zero (null pointer) and check whether it is null and open the log file as appropriate - but the code in the existing log_out() should be dealing with that anyway.

The advantage to this solution is that you can simply call it as if it was a variant of printf(); indeed, it is a minor variant on printf().

If you don't have the code to log_out(), consider whether you can replace it with a variant such as the one outlined above. Whether you can use the same name will depend on your application framework and the ultimate source of the current log_out() function. If it is in the same object file as another indispensable function, you would have to use a new name. If you cannot work out how to replicate it exactly, you will have to use some variant like those given in other answers that allocates an appropriate amount of memory.

void log_out_wrapper(const char *fmt, ...)
{
    va_list args;
    size_t  len;
    char   *space;

    va_start(args, fmt);
    len = vsnprintf(0, 0, fmt, args);
    va_end(args);
    if ((space = malloc(len + 1)) != 0)
    {
         va_start(args, fmt);
         vsnprintf(space, len+1, fmt, args);
         va_end(args);
         log_out(space);
         free(space);
    }
    /* else - what to do if memory allocation fails? */
}

Obviously, you now call the log_out_wrapper() instead of log_out() - but the memory allocation and so on is done once. I reserve the right to be over-allocating space by one unnecessary byte - I've not double-checked whether the length returned by vsnprintf() includes the terminating null or not.

If you have a return value you need to send to the UI you can use the generic version like this:

This is being called from an MVVM ViewModel in my case.

var updateManifest = Task<ShippingManifest>.Run(() =>
    {
        Thread.Sleep(5000);  // prove it's really working!

        // GenerateManifest calls service and returns 'ShippingManifest' object 
        return GenerateManifest();  
    })

    .ContinueWith(manifest =>
    {
        // MVVM property
        this.ShippingManifest = manifest.Result;

        // or if you are not using MVVM...
        // txtShippingManifest.Text = manifest.Result.ToString();    

        System.Diagnostics.Debug.WriteLine("UI manifest updated - " + DateTime.Now);

    }, TaskScheduler.FromCurrentSynchronizationContext());

The problem is that you aren't correctly escaping the input string, try:

echo "\"member\":\"time\"" | grep -e "member\""

Alternatively, you can use unescaped double quotes within single quotes:

echo '"member":"time"' | grep -e 'member"'

It's a matter of preference which you find clearer, although the second approach prevents you from nesting your command within another set of single quotes (e.g. ssh 'cmd').

If your constructor is similar to this one:

public Example(String example) {
    if (example == null) {
        throw new NullPointerException();
    }
    //do fun things with valid example here
}

Then, when you run this JUnit test you will get a green bar:

@Test(expected = NullPointerException.class)
public void constructorShouldThrowNullPointerException() {
    Example example = new Example(null);
}

You can remove the "not null" property from your column in mysql table if not necessary. when you remove "not null" property no need for "0000-00-00 00:00:00" conversion and problem is gone.

At least worked for me.

You can convert in one line :

public static LocalDate getLocalDateFromDate(Date date){
   return LocalDate.from(Instant.ofEpochMilli(date.getTime()).atZone(ZoneId.systemDefault()));
}

Here's a solution that works for environments that don't have the string library (Linux kernel, embedded systems, etc):

#define FILENAME ({ \
    const char* filename_start = __FILE__; \
    const char* filename = filename_start; \
    while(*filename != '\0') \
        filename++; \
    while((filename != filename_start) && (*(filename - 1) != '/')) \
        filename--; \
    filename; })

Now just use FILENAME instead of __FILENAME__. Yes, it's still a runtime thing but it works.

I also tried a very simple app on 10.8 (one button, sets text on a label). It crashed at startup, as Greg Parker stated:

Dyld Error Message:
  Symbol not found: __dispatch_source_type_memorypressure
  Referenced from: /Volumes/*/SwifTest.app/Contents/MacOS/../Frameworks/libswiftDispatch.dylib
  Expected in: /usr/lib/libSystem.B.dylib
in /Volumes/*/SwifTest.app/Contents/MacOS/../Frameworks/libswiftDispatch.dylib

(This was using a deployment target of 10.7)

You should't write data-toggle="modal" in the element which triggered the modal (like a button), and you manually can show the modal with:

$('#myModal').modal('show');

and hide with:

$('#myModal').modal('hide');

To write it with a while loop you can do:

ls -f /var | while read -r file; do cmd $file; done

The primary disadvantage of this is that cmd is run in a subshell, which causes some difficulty if you are trying to set variables. The main advantages are that the shell does not need to load all of the filenames into memory, and there is no globbing. When you have a lot of files in the directory, those advantages are important (that's why I use -f on ls; in a large directory ls itself can take several tens of seconds to run and -f speeds that up appreciably. In such cases 'for file in /var/*' will likely fail with a glob error.)

In generally, java gets installed at /usr/lib/jvm . That is where my sun jdk is installed. check if it is same for open jdk also.

I have used this URL to obtain multiple currency market quotes.

http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=USD=X,CAD=X,EUR=X

"USD",1.0000
"CAD",1.2458
"EUR",0.8396

They can be parsed in PHP like this:

$symbols = ['USD=X', 'CAD=X', 'EUR=X'];
$url = "http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=".join($symbols, ',');

$quote = array_map( 'str_getcsv', file($url) );

foreach ($quote as $key => $symb) {
    $symbol = $quote[$key][0];
    $value = $quote[$key][1];
}

You might get Component unavailable if you import the jQuery script directly.

Maybe it's what @Conley was talking about...

You can use

@require        http://userscripts.org/scripts/source/85365.user.js

which is an modified version to work on Greasemonkey, and then get the jQuery object

var $ = unsafeWindow.jQuery;
$("div").css("display", "none");

        Set<String> keyList = new HashSet();
        Pattern regex = Pattern.compile("#\\{(.*?)\\}");
        Matcher matcher = regex.matcher("Content goes here");
        while(matcher.find()) {
            keyList.add(matcher.group(1)); 
        }
        return keyList;

This is what I finally could do for installing psych package in R-3.4.1 when I got the same warning

1:Googled for that package.

2:downloaded it manually having tar.gz extension

3:Chose the option "Package Archive File (.zip;.tar.gz)" for install packages in R

4:browsed locally to the place where it was downloaded and clicked install

You may get a warning: dependencies 'xyz' not available for the package ,then first install those from the repository and then do steps 3-4 .

I kind of run into the same issue. I wanted my message box to display the message and the vendorcontractexpiration. This is what I did:

Dim ab As String
Dim cd As String

ab = "THE CONTRACT FOR THIS VENDOR WILL EXPIRE ON "
cd = VendorContractExpiration


If InvoiceDate >= VendorContractExpiration - 120 And InvoiceDate < VendorContractExpiration Then

MsgBox [ab] & [cd], vbCritical, "WARNING"

End If

I solved this by updating my app theme to inherit from material components.

<style name="Theme.MyApp" parent="Theme.MaterialComponents.DayNight">
    <!-- ... -->
</style>

you can try setting the padding instead of the height/width.

If in addition you want to pipe the output to a separate file, you can do:

On a Sun JVM:

-Xloggc:C:\whereever\jvm.log -verbose:gc -XX:+PrintGCDateStamps

ON an IBM JVM:

-Xverbosegclog:C:\whereever\jvm.log 

You can use js2py context to execute your js code and get output from document.write with mock document object:

import js2py

js = """
var output;
document = {
    write: function(value){
        output = value;
    }
}
""" + your_script

context = js2py.EvalJs()
context.execute(js)
print(context.output)

If you are not root user then, use following commands:

There are two ways to do it -

1.

sudo vi path_to_file/file_name

Press Esc and then type below respectively

:wq //save and exit
:q! //exit without saving

2. sudo nano path_to_file/file_name

When using nano: after you finish editing press ctrl+x then it will ask save Y/N.
If you want to save press Y, if not press N. And press enter to exit the editor.

This may be a long shot, but Crystal Reports for Eclipse is free. I'm not sure if it will work, but if all you need is to edit some static text, you could get that version of CR and get the job done.

Just use the css style "white-space: pre-wrap" and you should be good to go. I've had the same issue where I need to handle error messages for which the line breaks and white spaces are really particular. I just added this inline where I was binding the data and it works like Charm!

 <?php if (date("H") < "12" && date("H")>"6") { ?>
   src="<?php bloginfo('template_url'); ?>/images/img/morning.gif" 
 <?php } elseif (date("H") > "12" && date("H")<"17") { ?>
 src="<?php bloginfo('template_url'); ?>/images/img/noon.gif" 
  <?php } elseif (date("H") > "17" && date("H")<"21") { ?>
   src="<?php bloginfo('template_url'); ?>/images/img/evening.gif" 
  <?php } elseif (date("H") > "21" && date("H")<"24") { ?>
  src="<?php bloginfo('template_url'); ?>/images/img/night.gif" 
  <?php }else { ?>
  src="<?php bloginfo('template_url'); ?>/images/img/mid_night.gif" 
  <?php } ?>

If you want to change just on one page, add the following style rule:

 #myCustomDivID .row {
     margin-top:20px;
 }

HTML provide only input type="time" If you are using bootstrap then you can use timepicker. You can get code from this URL http://jdewit.github.io/bootstrap-timepicker May be it will help you

Please find example below, it might help you

for testing you can use any tool like RestClient (http://code.google.com/p/rest-client/)

The documentation is your friend, NSString supports a call substringWithRange that can shorten the string that you have an return the shortened String. You cannot modify an instance of NSString it is immutable. If you have an NSMutableString is has a method called deleteCharactersInRange that can modify the string in place

...
NSRange r;
r.location = 0;
r.size = [mutable length]-1;
NSString* shorted = [stringValue substringWithRange:r];
...

No magic involved, just subtract from the offset top of the element

$('html, body').animate({scrollTop: $('#contact').offset().top -100 }, 'slow');

In c++11, you can use std::regex_replace:

#include <string>

When using Netbean, go under project tab and click the dropdown button there to select Libraries folder. Right Click on d Library folder and select 'Add JAR/Folder'. Locate the mysql-connectore-java.*.jar file where u have it on ur system. This worked for me and I hope it does for u too. Revert if u encounter any problem

You could use substr, I guess:

$string2 = substr($string1, 0, 100);

or mb_substr for multi-byte strings:

$string2 = mb_substr($string1, 0, 100);

You could create a function wich uses this function and appends for instance '...' to indicate that it was shortened. (I guess there's allready a hundred similar replies when this is posted...)

You should make a habit of looking at the documentation for stuff like this. It's very useful and will improve your skills very quickly. Here's the relevant bit when you do git help diff

   git diff [options] [--no-index] [--] <path> <path>

The two <path>s are what you need to change to the directories in question.

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

roenving is correct BUT you need to change the test to:

if(element.nodeType == 1) {
//code
}

because nodeType of 3 is actually a text node and nodeType of 1 is an HTML element. See http://www.w3schools.com/Dom/dom_nodetype.asp

Switch statements with String cases have been implemented in Java SE 7, at least 16 years after they were first requested. A clear reason for the delay was not provided, but it likely had to do with performance.

Implementation in JDK 7

The feature has now been implemented in javac with a "de-sugaring" process; a clean, high-level syntax using String constants in case declarations is expanded at compile-time into more complex code following a pattern. The resulting code uses JVM instructions that have always existed.

A switch with String cases is translated into two switches during compilation. The first maps each string to a unique integer—its position in the original switch. This is done by first switching on the hash code of the label. The corresponding case is an if statement that tests string equality; if there are collisions on the hash, the test is a cascading if-else-if. The second switch mirrors that in the original source code, but substitutes the case labels with their corresponding positions. This two-step process makes it easy to preserve the flow control of the original switch.

Switches in the JVM

For more technical depth on switch, you can refer to the JVM Specification, where the compilation of switch statements is described. In a nutshell, there are two different JVM instructions that can be used for a switch, depending on the sparsity of the constants used by the cases. Both depend on using integer constants for each case to execute efficiently.

If the constants are dense, they are used as an index (after subtracting the lowest value) into a table of instruction pointers—the tableswitch instruction.

If the constants are sparse, a binary search for the correct case is performed—the lookupswitch instruction.

In de-sugaring a switch on String objects, both instructions are likely to be used. The lookupswitch is suitable for the first switch on hash codes to find the original position of the case. The resulting ordinal is a natural fit for a tableswitch.

Both instructions require the integer constants assigned to each case to be sorted at compile time. At runtime, while the O(1) performance of tableswitch generally appears better than the O(log(n)) performance of lookupswitch, it requires some analysis to determine whether the table is dense enough to justify the space–time tradeoff. Bill Venners wrote a great article that covers this in more detail, along with an under-the-hood look at other Java flow control instructions.

Before JDK 7

Prior to JDK 7, enum could approximate a String-based switch. This uses the static valueOf method generated by the compiler on every enum type. For example:

Pill p = Pill.valueOf(str);
switch(p) {
  case RED:  pop();  break;
  case BLUE: push(); break;
}

encodeURIComponent(string) will do it:

encodeURIComponent("Robert'); DROP TABLE Students;--")
//>> "Robert')%3B%20DROP%20TABLE%20Students%3B--"

Passing SQL around in a query string might not be a good plan though,

see this one

I made a Prototype Version of this:

String.prototype.strip = function() {
  var translate_re = /[öäüÖÄÜß ]/g;
  var translate = {
    "ä":"a", "ö":"o", "ü":"u",
    "Ä":"A", "Ö":"O", "Ü":"U",
    " ":"_", "ß":"ss"   // probably more to come
  };
    return (this.replace(translate_re, function(match){
        return translate[match];})
    );
};

Use like:

var teststring = 'ä ö ü Ä Ö Ü ß';
teststring.strip();

This will will change the String to a_o_u_A_O_U_ss

function isDecimal(n){
    if(n == "")
        return false;

    var strCheck = "0123456789";
    var i;

    for(i in n){
        if(strCheck.indexOf(n[i]) == -1)
            return false;
    }
    return true;
}

How was the database exported?

• If it was exported using exp and a full schema was exported, then

  1. Create the user:

     create user <username> identified by <password> default tablespace <tablespacename> quota unlimited on <tablespacename>;
     

  2. Grant the rights:

     grant connect, create session, imp_full_database to <username>;
     

  3. Start the import with imp:

     imp <username>/<password>@<hostname> file=<filename>.dmp log=<filename>.log full=y;
     

• If it was exported using expdp, then start the import with impdp:

  impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;
  

Looking at the error log, it seems you have not specified the directory, so Oracle tries to find the dmp file in the default directory (i.e., E:\app\Vensi\admin\oratest\dpdump\).

Either move the export file to the above path or create a directory object to pointing to the path where the dmp file is present and pass the object name to the impdp command above.

LEFT is not a function in Oracle. This probably came from someone familiar with SQL Server:

Returns the left part of a character string with the specified number of characters.

I had this problem, too. It turns out that the problem and solution are quite simple. When an Xcode user runs an app on a device using their free personal account, the Bundle ID is registered to the personal account. Then, when the user upgrades to a paid Apple Dev account and tries to create an App ID using that Bundle ID - the backend system thinks that Bundle ID has been taken.

Fill out the form here at this website: https://developer.apple.com/contact/submit/ under the "Certificates, Identifiers, Profilescategory”. I did this and the problem was solved in less than 12 hours. This was Apple’s emailed response: "When you install an app on a device from Xcode using your Personal Team, the Bundle ID is registered to that account. I have deleted the Bundle ID "com.AppVolks.Random-Ruby” so it can now be registered on your paid membership.”

Hope that helps!

Well, this solution might sound very silly, but can save you in certain conditions.

A friend of mine just ran into accidentally committing very some huge files (four auto-generated files ranging between 3GB to 5GB each) and then made some additional code commits on top of that before realizing the problem that git push wasn't working any longer!

The files had been listed in .gitignore but after renaming the container folder, they got exposed and committed! And now there were a few more commits of the code on top of that, but push was running forever (trying to upload GB of data!) and finally would fail due to Github's file size limits.

The problem with interactive rebase or anything similar was that they would deal with poking around these huge files and would take forever to do anything. Nevertheless, after spending almost an hour in the CLI, we weren't sure if the files (and deltas) are actually removed from the history or simply not included in the current commits. The push wasn't working either and my friend was really stuck.

So, the solution I came up with was:

1. Rename current git folder to ~/Project-old.
2. Clone the git folder again from github (to ~/Project).
3. Checkout to the same branch.
4. Manually cp -r the files from ~/Project-old folder to ~/Project.
5. Make sure the massive files, that are not needed to be checked in are mved, and included in .gitignore properly.
6. Also make sure you don't overwrite .git folder in the recently-cloned ~/Project by the old one. That's where the logs of the problematic history lives!
7. Now review the changes. It should be the union of all the recent commits, excluding the problematic files.
8. Finally commit the changes, and it's good to be push'ed.

The biggest problem with this solution is, it deals with manual copying some files, and also it merges all the recent commits into one (obviously with a new commit-hash.) B

The big benefits are that, it is very clear in every step, it works great for huge files (as well as sensitive ones), and it doesn't leave any trace in history behind!

Implementation 1 returns the magnitude of the vector that would result from a regular 3D cross product of the input vectors, taking their Z values implicitly as 0 (i.e. treating the 2D space as a plane in the 3D space). The 3D cross product will be perpendicular to that plane, and thus have 0 X & Y components (thus the scalar returned is the Z value of the 3D cross product vector).

Note that the magnitude of the vector resulting from 3D cross product is also equal to the area of the parallelogram between the two vectors, which gives Implementation 1 another purpose. In addition, this area is signed and can be used to determine whether rotating from V1 to V2 moves in an counter clockwise or clockwise direction. It should also be noted that implementation 1 is the determinant of the 2x2 matrix built from these two vectors.

Implementation 2 returns a vector perpendicular to the input vector still in the same 2D plane. Not a cross product in the classical sense but consistent in the "give me a perpendicular vector" sense.

Note that 3D euclidean space is closed under the cross product operation--that is, a cross product of two 3D vectors returns another 3D vector. Both of the above 2D implementations are inconsistent with that in one way or another.

Hope this helps...

Why not use the JPDA and attach to the launched process from a separate debugger process ? You should be able to specify the appropriate options in Maven to launch your process with the debugging hooks enabled. This article has more information.

If you don't want to go with separate struct definition for nested struct and you don't like second method suggested by @OneOfOne you can use this third method:

package main
import "fmt"
type Configuration struct {
    Val   string
    Proxy struct {
        Address string
        Port    string
    }
}

func main() {
    c := &Configuration{
        Val: "test",
    }

    c.Proxy.Address = `127.0.0.1`
    c.Proxy.Port = `8080`
}

The accepted answer wasn't working for me when trying to parse the registry for uninstall strings, and execute them. Turns out I didn't need the call to Invoke-Expression after all.

I finally came across this nice template for seeing how to execute uninstall strings:

$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
$app = 'MyApp'
$apps= @{}
Get-ChildItem $path | 
    Where-Object -FilterScript {$_.getvalue('DisplayName') -like $app} | 
    ForEach-Object -process {$apps.Set_Item(
        $_.getvalue('UninstallString'),
        $_.getvalue('DisplayName'))
    }

foreach ($uninstall_string in $apps.GetEnumerator()) {
    $uninstall_app, $uninstall_arg = $uninstall_string.name.split(' ')
    & $uninstall_app $uninstall_arg
}

This works for me, namely because $app is an in house application that I know will only have two arguments. For more complex uninstall strings you may want to use the join operator. Also, I just used a hash-map, but really, you'd probably want to use an array.

Also, if you do have multiple versions of the same application installed, this uninstaller will cycle through them all at once, which confuses MsiExec.exe, so there's that too.

the answer is already exist above, but I would like to add some thing.. you can specify the following in your @font-face

@font-face {
  font-family: 'Name You Font';
  src: url('assets/font/xxyourfontxxx.eot');
  src: local('Cera Pro Medium'), local('CeraPro-Medium'),
  url('assets/font/xxyourfontxxx.eot?#iefix') format('embedded-opentype'),
  url('assets/font/xxyourfontxxx.woff') format('woff'),
  url('assets/font/xxyourfontxxx.ttf') format('truetype');
  font-weight: 500;
  font-style: normal;
}

So you can just indicate your fontfamily name that you already choosed

NOTE: the font-weight and font-style depend on your .woff .ttf ... files

Here's some code that I ended up writing, based upon @Andrei's answer but without the elegancy/simplicity. The advantage is that it allows a more complex recursive merge and also differs between elements that should be connected with rbind and those that are just connected with c:

# Decided to move this outside the mapply, not sure this is 
# that important for speed but I imagine redefining the function
# might be somewhat time-consuming
mergeLists_internal <- function(o_element, n_element){
  if (is.list(n_element)){
    # Fill in non-existant element with NA elements
    if (length(n_element) != length(o_element)){
      n_unique <- names(n_element)[! names(n_element) %in% names(o_element)]
      if (length(n_unique) > 0){
        for (n in n_unique){
          if (is.matrix(n_element[[n]])){
            o_element[[n]] <- matrix(NA, 
                                     nrow=nrow(n_element[[n]]), 
                                     ncol=ncol(n_element[[n]]))
          }else{
            o_element[[n]] <- rep(NA, 
                                  times=length(n_element[[n]]))
          }
        }
      }

      o_unique <- names(o_element)[! names(o_element) %in% names(n_element)]
      if (length(o_unique) > 0){
        for (n in o_unique){
          if (is.matrix(n_element[[n]])){
            n_element[[n]] <- matrix(NA, 
                                     nrow=nrow(o_element[[n]]), 
                                     ncol=ncol(o_element[[n]]))
          }else{
            n_element[[n]] <- rep(NA, 
                                  times=length(o_element[[n]]))
          }
        }
      }
    }  

    # Now merge the two lists
    return(mergeLists(o_element, 
                      n_element))

  }
  if(length(n_element)>1){
    new_cols <- ifelse(is.matrix(n_element), ncol(n_element), length(n_element))
    old_cols <- ifelse(is.matrix(o_element), ncol(o_element), length(o_element))
    if (new_cols != old_cols)
      stop("Your length doesn't match on the elements,",
           " new element (", new_cols , ") !=",
           " old element (", old_cols , ")")
  }

  return(rbind(o_element, 
               n_element, 
               deparse.level=0))
  return(c(o_element, 
           n_element))
}
mergeLists <- function(old, new){
  if (is.null(old))
    return (new)

  m <- mapply(mergeLists_internal, old, new, SIMPLIFY=FALSE)
  return(m)
}

Here's my example:

v1 <- list("a"=c(1,2), b="test 1", sublist=list(one=20:21, two=21:22))
v2 <- list("a"=c(3,4), b="test 2", sublist=list(one=10:11, two=11:12, three=1:2))
mergeLists(v1, v2)

This results in:

$a
     [,1] [,2]
[1,]    1    2
[2,]    3    4

$b
[1] "test 1" "test 2"

$sublist
$sublist$one
     [,1] [,2]
[1,]   20   21
[2,]   10   11

$sublist$two
     [,1] [,2]
[1,]   21   22
[2,]   11   12

$sublist$three
     [,1] [,2]
[1,]   NA   NA
[2,]    1    2

Yeah, I know - perhaps not the most logical merge but I have a complex parallel loop that I had to generate a more customized .combine function for, and therefore I wrote this monster :-)

You can use

set define off

Using this it won't prompt for the input

hai sir

There is one event which is default associate with any webcontrol. For example, in case of Button click event, in case of Check box CheckChangedEvent is there. So in case of AutoPostBack true these events are called by default and event handle at server sid

I followed these steps (for Mac).

In /etc/ssh/sshd_config change

#ChallengeResponseAuthentication yes
#PasswordAuthentication yes

to

ChallengeResponseAuthentication no
PasswordAuthentication no

Now generate the RSA key:

ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa

(For me an RSA key worked. A DSA key did not work.)

A private key will be generated in ~/.ssh/id_rsa along with ~/.ssh/id_rsa.pub (public key).

Now move to the .ssh folder: cd ~/.ssh

Enter rm -rf authorized_keys (sometimes multiple keys lead to an error).

Enter vi authorized_keys

Enter :wq to save this empty file

Enter cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys

Restart the SSH:

sudo launchctl stop com.openssh.sshd
sudo launchctl start com.openssh.sshd

Force Delete a Local Branch:

$ git branch -D <branch-name>

[NOTE]:

-D is a shortcut for --delete --force.

I don't believe you can do it directly. One workaround would be to have a private internal implementation of method2 in the superclass, and call that. For example:

public class SuperClass
{
    public void method1()
    {
        System.out.println("superclass method1");
        this.internalMethod2();
    }

    public void method2()
    {
        this.internalMethod2(); 
    }
    private void internalMethod2()
    {
        System.out.println("superclass method2");
    }

}

From Java SE 6 HotSpot[tm] Virtual Machine Garbage Collection Tuning

the following

Excessive GC Time and OutOfMemoryError

The concurrent collector will throw an OutOfMemoryError if too much time is being spent in garbage collection: if more than 98% of the total time is spent in garbage collection and less than 2% of the heap is recovered, an OutOfMemoryError will be thrown. This feature is designed to prevent applications from running for an extended period of time while making little or no progress because the heap is too small. If necessary, this feature can be disabled by adding the option -XX:-UseGCOverheadLimit to the command line.

The policy is the same as that in the parallel collector, except that time spent performing concurrent collections is not counted toward the 98% time limit. In other words, only collections performed while the application is stopped count toward excessive GC time. Such collections are typically due to a concurrent mode failure or an explicit collection request (e.g., a call to System.gc()).

in conjunction with a passage further down

One of the most commonly encountered uses of explicit garbage collection occurs with RMIs distributed garbage collection (DGC). Applications using RMI refer to objects in other virtual machines. Garbage cannot be collected in these distributed applications without occasionally collection the local heap, so RMI forces full collections periodically. The frequency of these collections can be controlled with properties. For example,

java -Dsun.rmi.dgc.client.gcInterval=3600000

-Dsun.rmi.dgc.server.gcInterval=3600000 specifies explicit collection once per hour instead of the default rate of once per minute. However, this may also cause some objects to take much longer to be reclaimed. These properties can be set as high as Long.MAX_VALUE to make the time between explicit collections effectively infinite, if there is no desire for an upper bound on the timeliness of DGC activity.

Seems to imply that the evaluation period for determining the 98% is one minute long, but it might be configurable on Sun's JVM with the correct define.

Of course, other interpretations are possible.

You can use UNION All clause to perform multiple insert in a table.

ex:

INSERT INTO dbo.MyTable (ID, Name)
SELECT 123, 'Timmy'
UNION ALL
SELECT 124, 'Jonny'
UNION ALL
SELECT 125, 'Sally'

Check here

To make a dropdown list you need two properties:

1. a property to which you will bind to (usually a scalar property of type integer or string)
2. a list of items containing two properties (one for the values and one for the text)

In your case you only have a list of string which cannot be exploited to create a usable drop down list.

While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:

@model List<string>
@Html.DropDownList(
    "Foo", 
    new SelectList(
        Model.Select(x => new { Value = x, Text = x }),
        "Value",
        "Text"
    )
)

where Foo will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:

<select name="Foo" id="Foo">
    <option value="item 1">item 1</option>
    <option value="item 2">item 2</option>
    <option value="item 3">item 3</option>
    ...
</select>

This being said a far better view model for a drop down list is the following:

public class MyListModel
{
    public string SelectedItemId { get; set; }
    public IEnumerable<SelectListItem> Items { get; set; }
}

and then:

@model MyListModel
@Html.DropDownListFor(
    x => x.SelectedItemId,
    new SelectList(Model.Items, "Value", "Text")
)

and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId property of this view model to the corresponding Value of some element in the Items collection.

In case someone comes back to this later... None of the above worked for me. So I dug down into the guts of angular form validation and found the function they call to execute validators on a given field. This property is conveniently called $validate.

If you have a named form myForm, you can programmatically call myForm.my_field.$validate() to execute field validation. For example:

<div ng-form name="myForm">
    <input required name="my_field" type="text" ng-blur="myForm.my_field.$validate()">
</div>

Note that calling $validate has implications for your model. From the angular docs for ngModelCtrl.$validate:

Runs each of the registered validators (first synchronous validators and then asynchronous validators). If the validity changes to invalid, the model will be set to undefined, unless ngModelOptions.allowInvalid is true. If the validity changes to valid, it will set the model to the last available valid $modelValue, i.e. either the last parsed value or the last value set from the scope.

So if you're planning on doing something with the invalid model value (like popping a message telling them so), then you need to make sure allowInvalid is set to true for your model.

You can also use awk to make it a little bit prettier:

git rev-list --left-right --count  origin/develop...feature-branch | awk '{print "Behind "$1" - Ahead "$2""}'

You can even make an alias that always fetches origin first and then compares the branches

commit-diff = !"git fetch &> /dev/null && git rev-list --left-right --count"

Usually the process is the other way around. Do not go looking for situations where to use design patterns, look for code that can be optimized. When you have code that you think is not structured correctly. try to find a design pattern that will solve the problem.

Design patterns are meant to help you solve structural problems, do not go design your application just to be able to use design patterns.

I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.

1) Create environment variable in your environment.ts

export const environment = {
    ...
    // runtime variables
    isContentLoading: false,
    isDeployNeeded: false
}

2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template

import { environment } from 'environments/environment';

@Component(...)
export class TestComponent {
    ...
    env = environment;
}

3) Use it in template...

<app-spinner *ngIf='env.isContentLoading'></app-spinner>

in *.ts ...

env.isContentLoading = false 

(or just environment.isContentLoading in case you don't need it for template)

You can create your own set of globals within environment.ts like so:

export const globals = {
    isContentLoading: false,
    isDeployNeeded: false
}

and import directly these variables (y)

Surely a better answer would be, "Well, I'd ask the stackoverflow community and would probably have at least 4 really good answers within 5 minutes". Brains are good and all, but I'd place a higher value on someone who knows how to work with others to get a solution.

You could also use the generic function cbind() and lm() without the intercept:

Either I'm doing it wrongly, or the accepted answer does not work anymore with the current git.

I have actually found the proper solution and posted it under almost the same question here. For more details head there.

Solution:

# Ignore everything inside Resources/ directory
/Resources/**
# Except for subdirectories(won't be committed anyway if there is no committed file inside)
!/Resources/**/
# And except for *.foo files
!*.foo

This is my best solution if I understood the question well:

Use of $object->first() method to run the code inside if statement once, that is when on the first loop. The same concept is true with $object->last().

    @if($object->first())
        <div class="panel user-list">
          <table id="myCustomTable" class="table table-hover">
              <thead>
                  <tr>
                     <th class="col-email">Email</th>
                  </tr>
              </thead>
              <tbody>
    @endif

    @foreach ($object as $data)
        <tr class="gradeX">
           <td class="col-name"><strong>{{ $data->email }}</strong></td>
        </tr>
    @endforeach

    @if($object->last())
                </tbody>
            </table>
        </div>
    @endif

to preserve the console output, that is, write to a file and also have it displayed on the console, you could use a class like:

    public class TeePrintStream extends PrintStream {
        private final PrintStream second;

        public TeePrintStream(OutputStream main, PrintStream second) {
            super(main);
            this.second = second;
        }

        /**
         * Closes the main stream. 
         * The second stream is just flushed but <b>not</b> closed.
         * @see java.io.PrintStream#close()
         */
        @Override
        public void close() {
            // just for documentation
            super.close();
        }

        @Override
        public void flush() {
            super.flush();
            second.flush();
        }

        @Override
        public void write(byte[] buf, int off, int len) {
            super.write(buf, off, len);
            second.write(buf, off, len);
        }

        @Override
        public void write(int b) {
            super.write(b);
            second.write(b);
        }

        @Override
        public void write(byte[] b) throws IOException {
            super.write(b);
            second.write(b);
        }
    }

and used as in:

    FileOutputStream file = new FileOutputStream("test.txt");
    TeePrintStream tee = new TeePrintStream(file, System.out);
    System.setOut(tee);

(just an idea, not complete)

Just an important note: the accepted answer above will not work correctly for keyCode >= 144, i.e. period, comma, dash, etc. For those you should use a more general algorithm:

let chrCode = keyCode - 48 * Math.floor(keyCode / 48);
let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);

If you're curious as to why, this is apparently necessary because of the behavior of the built-in JS function String.fromCharCode(). For values of keyCode <= 96 it seems to map using the function:

chrCode = keyCode - 48 * Math.floor(keyCode / 48)

For values of keyCode > 96 it seems to map using the function:

chrCode = keyCode

If this seems like odd behavior then well..I agree. Sadly enough, it would be very far from the weirdest thing I've seen in the JS core.

document.onkeydown = function(e) {_x000D_
    let keyCode = e.keyCode;_x000D_
    let chrCode = keyCode - 48 * Math.floor(keyCode / 48);_x000D_
    let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);_x000D_
    console.log(chr);_x000D_
};

<input type="text" placeholder="Focus and Type"/>

Worked for me with this command:

yum install java-devel

The question I would ask is, why are you including the extra columns in your DataTable if they aren't required?

Maybe you should modify your SQL select statement so that it is looking at the specific criteria you are looking for as you are populating your DataTable.

You could also use LINQ to query your DataTable as Enumerable and create a List Object that represents only certain columns.

Other than that, hide the DataGridView Columns that you don't require.

Here's my simple solution that returns a unique integer.

function hashcode(obj) {
    var hc = 0;
    var chars = JSON.stringify(obj).replace(/\{|\"|\}|\:|,/g, '');
    var len = chars.length;
    for (var i = 0; i < len; i++) {
        // Bump 7 to larger prime number to increase uniqueness
        hc += (chars.charCodeAt(i) * 7);
    }
    return hc;
}

after_initialize method is deprecated, use the callback instead.

after_initialize :defaults

def defaults
  self.extras||={}
  self.other_stuff||="This stuff"
end

however, using :default in your migrations is still the cleanest way.

Had trouble undestanding this myself. Even after reading the answers here.

To properly understand the __init__ method you need to understand self.

The self Parameter

The arguments accepted by the __init__ method are :

def __init__(self, arg1, arg2):

But we only actually pass it two arguments :

instance = OurClass('arg1', 'arg2')

Where has the extra argument come from ?

When we access attributes of an object we do it by name (or by reference). Here instance is a reference to our new object. We access the printargs method of the instance object using instance.printargs.

In order to access object attributes from within the __init__ method we need a reference to the object.

Whenever a method is called, a reference to the main object is passed as the first argument. By convention you always call this first argument to your methods self.

This means in the __init__ method we can do :

self.arg1 = arg1
self.arg2 = arg2

Here we are setting attributes on the object. You can verify this by doing the following :

instance = OurClass('arg1', 'arg2')
print instance.arg1
arg1

values like this are known as object attributes. Here the __init__ method sets the arg1 and arg2 attributes of the instance.

I found my problem. The issue was that my integers were actually type numpy.int64.

FOR MySQL

CREATE TABLE newtable LIKE oldtable ; 
INSERT newtable SELECT * FROM oldtable ;

FOR MSSQL Use MyDatabase:

Select * into newCustomersTable  from oldCustomersTable;

This SQL is used for copying tables, here the contents of oldCustomersTable will be copied to newCustomersTable.
Make sure the newCustomersTable does not exist in the database.

robocopy "C:\Users\Angie\My Documents" "C:\test-backup\My Documents" /B /E /R:0 /CREATE /NP /TEE /XJ /LOG+:"CompleteBackupLog.txt"
robocopy "C:\Users\Angie\My Music" "C:\test-backup\My Music" /B /E /R:0 /CREATE /NP /TEE /XJ /LOG+:"CompleteBackupLog.txt"
robocopy "C:\Users\Angie\My Pictures" "C:\test-backup\My Pictures" /B /E /R:0 /CREATE /NP /TEE /XJ /LOG+:"CompleteBackupLog.txt"

there's a maxlength attribute

<input type="text" name="textboxname" maxlength="100" />

If you want the executable:

System.Reflection.Assembly.GetEntryAssembly().Location

If you want the assembly that's consuming your library (which could be the same assembly as above, if your code is called directly from a class within your executable):

System.Reflection.Assembly.GetCallingAssembly().Location

If you'd like just the filename and not the path, use:

Path.GetFileName(System.Reflection.Assembly.GetEntryAssembly().Location)

An alternative way is to install the Maven for Java plugin and create a maven project within Visual Studio. The steps are described in the official documentation:

1. From the Command Palette (Crtl+Shift+P), select Maven: Generate from Maven Archetype and follow the instructions, or
2. Right-click on a folder and select Generate from Maven Archetype.

From https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleDateString

The toLocaleDateString() method returns a string with a language sensitive representation of the date portion of this date. The new locales and options arguments let applications specify the language whose formatting conventions should be used and allow to customize the behavior of the function. In older implementations, which ignore the locales and options arguments, the locale used and the form of the string returned are entirely implementation dependent.

Long form:

const options = { weekday: 'long' };
const date = new Date();
console.log(date.toLocaleDateString('en-US', options));

One liner:

console.log(new Date().toLocaleDateString('en-US', { weekday: 'long' }));

Note: there are other language options for locale, but the one presented here for for US English

As you know this is UK format issue. You can do date conversion indirectly by using function.

CREATE FUNCTION  ChangeDateFormatFromUK
( 
   @DateColumn varchar(10)
)

RETURNS VARCHAR(10)
AS 
 BEGIN
    DECLARE @Year varchar(4), @Month varchar(2), @Day varchar(2), @Result varchar(10)
    SET @Year = (SELECT substring(@DateColumn,7,10))
    SET @Month = (SELECT substring(@DateColumn,4,5)) 
    SET @Day = (SELECT substring(@DateColumn,1,2))
   SET @Result  = @Year  + '/' @Month + '/' +  @Day

 RETURN @Result
END

To call this function

SELECT dbo.ChangeDateFormatFromUK([dates]) from table

Convert it normally to datetime

SELECT CONVERT(DATETIME,dbo.ChangeDateFormatFromUK([dates])) from table

In your Case, you can do

SELECT [dates] from table where CONVERT(DATETIME,dbo.ChangeDateFormatFromUK([dates])) > GetDate()   -- or any date

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

Just use String.IndexOf twice as in:

     string str = "My Test String";
     int index = str.IndexOf(' ');
     index = str.IndexOf(' ', index + 1);
     string result = str.Substring(0, index);

This was a strange problem since my hosts IIS shouldn't complain that it requires integrated pipeline mode when it already is in that mode as I stated in my question as:

I have searched a lot and unable to find anything except for directing the reader to change the pipeline from classic mode to integrated mode that which I already did with no luck..

Using Levi's directions, I put <%: System.Web.Hosting.HttpRuntime.UsingIntegratedPipeline %> and <%: System.Web.Hosting.HttpRuntime.IISVersion %>* on an empty aspx page and told my host what going on and asked them to fix the problem and confirm the problem using the page I uploaded... I checked very often if something has changed at the state of the page and I can see that they struggled 3-4 hours to solve it...

When I asked what they have done to solve the problem, their answer was kind of 'classified', since they said:

Our team made the required changes on the server

The problem was all with my host.

* Update: As Ben stated in the comments

1. <%: System.Web.Hosting.HttpRuntime.UsingIntegratedPipeline %> and
2. <%: System.Web.Hosting.HttpRuntime.IISVersion %>

are no longer valid and they are now:

1. <%: System.Web.HttpRuntime.UsingIntegratedPipeline %> and
2. <%: System.Web.HttpRuntime.IISVersion %>

I came across the same error when trying to add the callback to an event listener. Strangely, setting the callback type to EventListener solved it. It looks more elegant than defining a whole function signature as a type, but I'm not sure if this is the correct way to do this.

class driving {
    // the answer from this post - this works
    // private callback: () => void; 

    // this also works!
    private callback:EventListener;

    constructor(){
        this.callback = () => this.startJump();
        window.addEventListener("keydown", this.callback);
    }

    startJump():void {
        console.log("jump!");
        window.removeEventListener("keydown", this.callback);
    }
}

if you are using GridView you can use something like Ian Hickson's solution.

crossAxisCount: MediaQuery.of(context).size.width <= 400.0 ? 3 : MediaQuery.of(context).size.width >= 1000.0 ? 5 : 4

There is no standard way to do this. You need to use 3rd party tools such as ApexSQL Restore or SQL Virtual Restore. These tools don’t really read the backup file directly. They get SQL Server to “think” of backup files as if these were live databases.

You need to define the size of file...

header('Content-Length: ' . filesize($file));

And this line is wrong:

header("Content-Disposition:inline;filename='$filename");

You messed up quotas.

Assuming you are a PyCharm User, its pretty easy to install Flask This will help users without shell pip access also.

• Open Settings(Ctrl+Alt+s) >>
• Goto Project Interpreter>>
• Double click pip>> Search for flask
• Select and click Install Package ( Check Install to site users if intending to use Flask for this project alone Done!!!

Cases in which flask is not shown in pip: Open Manage Repository>> Add(+) >> Add this following url

https://www.palletsprojects.com/p/flask/

Now back to pip, it will show related packages of flask,

• select flask>>
• install package>>

Voila!!!

Unfortunately DEBUG is overloaded heavily. For instance, it's recommended to always generate and save a pdb file for RELEASE builds. Which means one of the -Zx flags, and -DEBUG linker option. While _DEBUG relates to special debug versions of runtime library such as calls to malloc and free. Then NDEBUG will disable assertions.

function changeImage(a) so there is no such thing as a.src => just use a.

Inspired from @Hamed, I added the following and it worked for me:

display: inline-block; overflow: hidden; 

One advantage not yet mentioned of a TreeSet is that its has greater "locality", which is shorthand for saying (1) if two entries are nearby in the order, a TreeSet places them near each other in the data structure, and hence in memory; and (2) this placement takes advantage of the principle of locality, which says that similar data is often accessed by an application with similar frequency.

This is in contrast to a HashSet, which spreads the entries all over memory, no matter what their keys are.

When the latency cost of reading from a hard drive is thousands of times the cost of reading from cache or RAM, and when the data really is accessed with locality, the TreeSet can be a much better choice.

A friend was asking me about this subject recently, so I thought I'd post how I handle command-line arguments in batch files.

This technique has a bit of overhead as you'll see, but it makes my batch files very easy to understand and quick to implement. As well as supporting the following structures:

>template.bat [-f] [--flag] [/f] [--namedvalue value] arg1 [arg2][arg3][...]

The jist of it is having the :init, :parse, and :main functions.

Example usage

>template.bat /?
test v1.23
This is a sample batch file template,
providing command-line arguments and flags.

USAGE:
test.bat [flags] "required argument" "optional argument"

/?, --help           shows this help
/v, --version        shows the version
/e, --verbose        shows detailed output
-f, --flag value     specifies a named parameter value

>template.bat          <- throws missing argument error
(same as /?, plus..)
****                                   ****
****    MISSING "REQUIRED ARGUMENT"    ****
****                                   ****

>template.bat -v
1.23

>template.bat --version
test v1.23
This is a sample batch file template,
providing command-line arguments and flags.

>template.bat -e arg1
**** DEBUG IS ON
UnNamedArgument:    "arg1"
UnNamedOptionalArg: not provided
NamedFlag:          not provided

>template.bat --flag "my flag" arg1 arg2

UnNamedOptionalArg: "arg2"
NamedFlag:          "my flag"

I merge projects slightly manually, which allows me to avoid needing to deal with merge conflicts.

first, copy in the files from the other project however you want them.

cp -R myotherproject newdirectory
git add newdirectory

next pull in the history

git fetch path_or_url_to_other_repo

tell git to merge in the history of last fetched thing

echo 'FETCH_HEAD' > .git/MERGE_HEAD

now commit however you normally would commit

git commit

I was running on Win7, Tomcat7 with maven-pom setup on Eclipse Mars with maven project enabled. On a NOT running server I only had to change from 3.1 to 3.0 on this screen:

For me it was important to have Dynamic Web Module disabled! Then change the version and then enable Dynamic Web Module again.

There are very good answers with detailed explanation to this post. I just would like to refer that there is another explanation with visual representation for the meaning of Frame, Bounds, Center, Transform, Bounds Origin in WWDC 2011 video Understanding UIKit Rendering starting from @4:22 till 20:10

For me i had already created a folder with name excel in wwroot D:\working directory\OnlineExam\wwwroot\excel And i was trying to copy a file with name excel which was already existing as a folder name. the path which was required was D:\working directory\OnlineExam\wwwroot\excel\finance.csv so according i changed the code as below

string copyPath = Path.Combine(_webHostEnvironment.WebRootPath, "excel\\finance");
                    questionExcelUpload.Upload.CopyTo(new FileStream(copyPath, FileMode.Create));

Basically check if a folder or a file with same name as your path exist already.

You cannot do that I'm afraid, but you can do the following in jQuery, if you don't want to add the attributes to the fields. Just place this inside your <head></head> tag

$(document).ready(function(){ 
  $(".inputClass").focus(function(){
    $(this).blur();
  }); 
});

If you are generating the fields in the DOM (with JS), you should do this instead:

$(document).ready(function(){ 
  $(document).on("focus", ".inputClass", function(){
    $(this).blur();
  }); 
});

Taken from above:

from scipy.stats import norm
>>> norm.cdf(1.96)

z = 1.96
p_value = 2 * norm.cdf(-np.abs(z))
0.04999579029644087

Here's a nice trick to read JSON from s3:

import json, boto3
s3 = boto3.resource("s3").Bucket("bucket")
json.load_s3 = lambda f: json.load(s3.Object(key=f).get()["Body"])
json.dump_s3 = lambda obj, f: s3.Object(key=f).put(Body=json.dumps(obj))

Now you can use json.load_s3 and json.dump_s3 with the same API as load and dump

data = {"test":0}
json.dump_s3(data, "key") # saves json to s3://bucket/key
data = json.load_s3("key") # read json from s3://bucket/key

In shell you assign to a variable without the dollar-sign:

TEST=`pwd`
echo $TEST

that's better (and can be nested) but is not as portable as the backtics:

TEST=$(pwd)
echo $TEST

Always remember: the dollar-sign is only used when reading a variable.

Series.apply(func, convert_dtype=True, args=(), **kwds)

args : tuple

x = my_series.apply(my_function, args = (arg1,))

If you have a pandas serie with NaN, and want to remove it (without loosing index):

serie = serie.dropna()

# create data for example
data = np.array(['g', 'e', 'e', 'k', 's']) 
ser = pd.Series(data)
ser.replace('e', np.NAN)
print(ser)

0      g
1    NaN
2    NaN
3      k
4      s
dtype: object

# the code
ser = ser.dropna()
print(ser)

0    g
3    k
4    s
dtype: object

I made a node module to automate this task: mddir

Usage

node mddir "../relative/path/"

To install: npm install mddir -g

To generate markdown for current directory: mddir

To generate for any absolute path: mddir /absolute/path

To generate for a relative path: mddir ~/Documents/whatever.

The md file gets generated in your working directory.

Currently ignores node_modules, and .git folders.

Troubleshooting

If you receive the error 'node\r: No such file or directory', the issue is that your operating system uses different line endings and mddir can't parse them without you explicitly setting the line ending style to Unix. This usually affects Windows, but also some versions of Linux. Setting line endings to Unix style has to be performed within the mddir npm global bin folder.

Line endings fix

Get npm bin folder path with:

npm config get prefix

Cd into that folder

brew install dos2unix

dos2unix lib/node_modules/mddir/src/mddir.js

This converts line endings to Unix instead of Dos

Then run as normal with: node mddir "../relative/path/".

Your syntax isn't quite right: you need to list the fields in order before the INTO, and the corresponding target variables after:

SELECT Id, dateCreated
INTO iId, dCreate
FROM products
WHERE pName = iName

Use following statement for error

be careful about your data take backup if data have in table.

 ALTER TABLE your_table_name CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;

Two ways of doing it.

Late binding

<asp:Calendar ID="planning" runat="server" SelectedDate="<%# DateTime.Now %>"></asp:Calendar>

Code behind way (Page_Load solution)

protected void Page_Load(object sender, EventArgs e)
{
    BindCalendar();
}

private void BindCalendar()
{
    planning.SelectedDate = DateTime.Today;
}

Altough, I strongly recommend to do it from a BindMyStuff way. Single entry point easier to debug. But since you seems to know your game, you're all set.

CookieManager.getInstance().setAcceptCookie(true); Normally it should work if your webview is already initialized

or try this:

CookieSyncManager.createInstance(this);
CookieManager cookieManager = CookieManager.getInstance();
cookieManager.removeAllCookie();
cookieManager.setAcceptCookie(true);

To be on the safe side use

os.getenv('FOO') or 'bar'

A corner case with the above answers is when the environment variable is set but is empty

For this special case you get

print(os.getenv('FOO', 'bar'))
# prints new line - though you expected `bar`

or

if "FOO" in os.environ:
    print("FOO is here")
# prints FOO is here - however its not

To avoid this just use or

os.getenv('FOO') or 'bar'

Then you get

print(os.getenv('FOO') or 'bar')
# bar

When do we have empty environment variables?

You forgot to set the value in the .env file

# .env
FOO=

or exported as

$ export FOO=

or forgot to set it in settings.py

# settings.py
os.environ['FOO'] = ''

Update: if in doubt, check out these one-liners

>>> import os; os.environ['FOO'] = ''; print(os.getenv('FOO', 'bar'))

$ FOO= python -c "import os; print(os.getenv('FOO', 'bar'))"

Using jQuery:

get_between <- function(str, first_character, last_character) {
    new_str = str.match(first_character + "(.*)" + last_character)[1].trim()
    return(new_str)
    }

string

my_string = 'and the thing that ! on the @ with the ^^ goes now' 

usage:

get_between(my_string, 'that', 'now')

result:

"! on the @ with the ^^ goes

Point 1:

If you want to write something into a file. means: it will remove anything already saved in the file and write the new content. use fs.promises.writeFile()

Point 2:

If you want to append something into a file. means: it will not remove anything already saved in the file but append the new item in the file content.then first read the file, and then add the content into the readable value, then write it to the file. so use fs.promises.readFile and fs.promises.writeFile()

example 1: I want to write a JSON object in my JSON file .

const fs = require('fs');
writeFile  ('./my_data.json' , {id:1, name:'my name'} )
async function writeFile  (filename ,writedata) {
    try {
        await fs.promises.writeFile(filename, JSON.stringify(writedata,null, 4), 'utf8');
       console.log ('data is written successfully in the file')
    }
    catch(err) {
        console.log ('not able to write data in the file ')
    }
}

example2 : if you want to append data to a JSON file. you want to add data {id:1, name:'my name'} to file my_data.json on the same folder root. just call append_data (file_path , data ) function.

It will append data in the JSON file if the file existed . or it will create the file and add the data to it.

   const fs = require('fs');
   data = {id:1, name:'my name'}
   file_path = './my_data.json'
   append_data (file_path , data )

   async function append_data (filename , data ) {

      if (fs.existsSync(filename)) {
         read_data = await readFile(filename)
         if (read_data == false) {
             console.log('not able to read file')
         }
         else {
             read_data.push(data)
             dataWrittenStatus = await writeFile(filename, read_data)
             if dataWrittenStatus == true {
               console.log('data added successfully')
             }
            else{
               console.log('data adding failed')
            }
        }
       else{
          dataWrittenStatus = await writeFile(filename, [data])
          if dataWrittenStatus == true {
             console.log('data added successfully')
          }
          else{
             console.log('data adding failed')
          }
      }
   }



async function readFile  (filePath) {
  try {
    const data = await fs.promises.readFile(filePath, 'utf8')
    return JSON.parse(data)
  }
 catch(err) {
     return false;
  }
}

async function writeFile  (filename ,writedata) {
  try {
      await fs.promises.writeFile(filename, JSON.stringify(writedata,null, 4), 'utf8');
      return true
  }
  catch(err) {
      return false
  }
}

Found the solution myself in the end. The problem was not with the LinearLayout, but with the ScrollView (seems weird, considering the fact that the ScrollView was expanding, while the LinearLayout wasn't).

The solution was to use android:fillViewport="true" on the ScrollView.

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

It's as easy as:

delete object.keyname;

or

delete object["keyname"];

There are a few problems with your code:

def MyThread ( threading.thread ):

• You can't subclass with a function; only with a class
• If you were going to use a subclass you'd want threading.Thread, not threading.thread

If you really want to do this with only functions, you have two options:

With threading:

import threading
def MyThread1():
    pass
def MyThread2():
    pass

t1 = threading.Thread(target=MyThread1, args=[])
t2 = threading.Thread(target=MyThread2, args=[])
t1.start()
t2.start()

With thread:

import thread
def MyThread1():
    pass
def MyThread2():
    pass

thread.start_new_thread(MyThread1, ())
thread.start_new_thread(MyThread2, ())

Doc for thread.start_new_thread

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

I arrived at this thread, and none of the above solutions turned out to apply to my case. It turns out, I simply had to remove a trailing slash from the <AllowedOrigin> URL in my bucket's CORS configuration.

Fails:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>http://www.mywebsite.com/</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

Wins:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>http://www.mywebsite.com</AllowedOrigin>
        <AllowedMethod>GET</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

I hope this saves someone some hair-pulling.

For the special date of January 1, 1970 there are multiple options.

For any other starting date you need to get the difference between the two dates in seconds. Subtracting two dates gives a timedelta object, which as of Python 2.7 has a total_seconds() function.

>>> (t-datetime.datetime(1970,1,1)).total_seconds()
1256083200.0

The starting date is usually specified in UTC, so for proper results the datetime you feed into this formula should be in UTC as well. If your datetime isn't in UTC already, you'll need to convert it before you use it, or attach a tzinfo class that has the proper offset.

As noted in the comments, if you have a tzinfo attached to your datetime then you'll need one on the starting date as well or the subtraction will fail; for the example above I would add tzinfo=pytz.utc if using Python 2 or tzinfo=timezone.utc if using Python 3.

To expand on katrmr's answer, if the container is stopped and can't be started due to an error, you'll need to commit it to an image. Then you can launch bash in the new image:

docker commit [CONTAINER_ID] temporary_image
docker run --entrypoint=bash -it temporary_image

You could do something using the grep command:

find . | grep -v '(dll|exe)$'

The -v flag on grep specifically means "find things that don't match this expression."

If you want to have a one liner without requiring a huge library like lodash, I suggest you to use deepmerge. (npm install deepmerge)

Then, you can do

deepmerge({ a: 1, b: 2, c: 3 }, { a: 2, d: 3 });

to get

{ a: 2, b: 2, c: 3, d: 3 }

This works nicely with complex objects and arrays. The nice thing is it comes with typings for TypeScript right away. A real all-rounder solution this is.

Try "sudo mysql -u root -p" please.

Given you use JQuery, you can do something like below :

HTML

<form id="myform">
    syn<input type="checkbox" name="checkfield" id="g01-01"  onclick="doalert()"/>
</form>

JS

function doalert() {
  if ($("#g01-01").is(":checked")) {
    alert ("hi");
  } else {
    alert ("bye");
  }
}

This is a quirk of the C grammar. A label (Cleanup:) is not allowed to appear immediately before a declaration (such as char *str ...;), only before a statement (printf(...);). In C89 this was no great difficulty because declarations could only appear at the very beginning of a block, so you could always move the label down a bit and avoid the issue. In C99 you can mix declarations and code, but you still can't put a label immediately before a declaration.

You can put a semicolon immediately after the label's colon (as suggested by Renan) to make there be an empty statement there; this is what I would do in machine-generated code. Alternatively, hoist the declaration to the top of the function:

int main (void) 
{
    char *str;
    printf("Hello ");
    goto Cleanup;
Cleanup:
    str = "World\n";
    printf("%s\n", str);
    return 0;
}

For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.

Try something like

convert -density 300 image.eps -resize 1024x1024 image.jpg

Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.

The order of the arguments matters! The -density X argument needs to go before image.eps because you want to affect the resolution that the input file is rendered at.

This is not super obvious in the manpage for convert, but is hinted at:

SYNOPSIS

convert [input-option] input-file [output-option] output-file

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

Try setting up sock5 proxy too. I was facing the same problem and it is solved by using the socks proxy

def install_proxy(PROXY_HOST,PROXY_PORT):
        fp = webdriver.FirefoxProfile()
        print PROXY_PORT
        print PROXY_HOST
        fp.set_preference("network.proxy.type", 1)
        fp.set_preference("network.proxy.http",PROXY_HOST)
        fp.set_preference("network.proxy.http_port",int(PROXY_PORT))
        fp.set_preference("network.proxy.https",PROXY_HOST)
        fp.set_preference("network.proxy.https_port",int(PROXY_PORT))
        fp.set_preference("network.proxy.ssl",PROXY_HOST)
        fp.set_preference("network.proxy.ssl_port",int(PROXY_PORT))  
        fp.set_preference("network.proxy.ftp",PROXY_HOST)
        fp.set_preference("network.proxy.ftp_port",int(PROXY_PORT))   
        fp.set_preference("network.proxy.socks",PROXY_HOST)
        fp.set_preference("network.proxy.socks_port",int(PROXY_PORT))   
        fp.set_preference("general.useragent.override","Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_3) AppleWebKit/537.75.14 (KHTML, like Gecko) Version/7.0.3 Safari/7046A194A")
        fp.update_preferences()
        return webdriver.Firefox(firefox_profile=fp)

Then call install_proxy ( ip , port ) from your program.

If you can get SSH to it you can an SSH Port-forwarded SVN server.

Use SSHs -L ( or -R , I forget, it always confuses me ) to make an ssh tunnel so that

127.0.0.1:3690 is really connecting to remote:3690 over the ssh tunnel, and then you can use it via

svn co svn://127.0.0.1/....

Yes, you can do it. An interface can extend multiple interfaces, as shown here:

interface Maininterface extends inter1, inter2, inter3 {  
  // methods
}

A single class can also implement multiple interfaces. What if two interfaces have a method defining the same name and signature?

There is a tricky point:

interface A {
    void test();
}

interface B {
    void test();
}

class C implements A, B {

    @Override
    public void test() {

    }     

}

Then single implementation works for both :).

Read my complete post here:

I think you should implement GestureDetector.OnGestureListener as described in Using GestureDetector to detect Long Touch, Double Tap, Scroll or other touch events in Android and androidsnippets and then implement tap logic in onSingleTapUp and move logic in onScroll events

David Findley writes about 3 different options you have for doing this, on his ASP.Net weblog.

Read the article multiple buttons in the same form to see his solutions, and the advantages and disadvantages of each. IMHO he provides a very elegant solution which makes use of attributes that you decorate your action with.

You can not access the docker's IP from outside of that host machine. If your browser is on another machine better to map the host port to container port by passing -p 8080:8080 to run command.

Passing -p you can map host port to container port and a proxy is set to forward all traffix for said host port to designated container port.

Using Java:

WebElement webElement = driver.findElement(By.xpath(""));//You can use xpath, ID or name whatever you like
webElement.sendKeys(Keys.TAB);
webElement.sendKeys(Keys.ENTER);

Date is Comparable so just create list of List<Date> and sort it using Collections.sort(). And use Collections.reverseOrder() to get comparator in reverse ordering.

From Java Doc

Returns a comparator that imposes the reverse ordering of the specified comparator. If the specified comparator is null, this method is equivalent to reverseOrder() (in other words, it returns a comparator that imposes the reverse of the natural ordering on a collection of objects that implement the Comparable interface).

A few notes and clarifications:

• placeholder='' inserts your text, but it is greyed out (in a tool-tip style format) and the moment the field is clicked, your text is replaced by an empty text field.

• value='' is not a <textarea> attribute, and only works for <input> tags, ie, <input type='text'>, etc. I don't know why the creators of HTML5 decided not to incorporate that, but that's the way it is for now.

• The best method for inserting text into <textarea> elements has been outlined correctly here as: <textarea> Desired text to be inserted into the field upon page load </textarea> When the user clicks the field, they can edit the text and it remains in the field (unlike placeholder='').

• Note: If you insert text between the <textarea> and </textarea> tags, you cannot use placeholder='' as it will be overwritten by your inserted text.

In my case, I had deleted a table using SET FOREIGN_KEY_CHECKS=0, then SET FOREIGN_KEY_CHECKS=1 after. When I went to reload the table, I got error 1215. The problem was there was another table in the database that had a foreign key to the table I had deleted and was reloading. Part of the reloading process involved changing a data type for one of the fields, which made the foreign key from the other table invalid, thus triggering error 1215. I resolved the problem by dropping and then reloading the other table with the new data type for the involved field.

While most people blindly follow the advice of the javadoc, there are very specific situations where you want to actually avoid toString(). For example, I'm using enums in my Java code, but they need to be serialized to a database, and back again. If I used toString() then I would technically be subject to getting the overridden behavior as others have pointed out.

Additionally one can also de-serialize from the database, for example, this should always work in Java:

MyEnum taco = MyEnum.valueOf(MyEnum.TACO.name());

Whereas this is not guaranteed:

MyEnum taco = MyEnum.valueOf(MyEnum.TACO.toString());

By the way, I find it very odd for the Javadoc to explicitly say "most programmers should". I find very little use-case in the toString of an enum, if people are using that for a "friendly name" that's clearly a poor use-case as they should be using something more compatible with i18n, which would, in most cases, use the name() method.

--version is a valid option from JDK 9 and it is not a valid option until JDK 8 hence you get the below:

Unrecognized option: --version
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

You can try installing JDK 9 or any version later and check for java --version it will work.

Alternately, from the installed JDK 9 or later versions you can see from java -help the below two options will be available:

    -version      print product version to the error stream and exit
    --version     print product version to the output stream and exit

where as in JDK 8 you will only have below when you execute java -help

    -version      print product version and exit

I hope it answers your question.

You can Try using :- git ls-files -s

The Good News is:

It's 100% working.

Just add something inside the script tag such as alert('voila!');. The right question you might want to ask perhaps, "Why didn't I see it in the DOM?".

Karl Swedberg has made a nice explanation to visitor's comment in jQuery API site. I don't want to repeat all his words, you can read directly there here (I found it hard to navigate through the comments there).

All of jQuery's insertion methods use a domManip function internally to clean/process elements before and after they are inserted into the DOM. One of the things the domManip function does is pull out any script elements about to be inserted and run them through an "evalScript routine" rather than inject them with the rest of the DOM fragment. It inserts the scripts separately, evaluates them, and then removes them from the DOM.

I believe that one of the reasons jQuery does this is to avoid "Permission Denied" errors that can occur in Internet Explorer when inserting scripts under certain circumstances. It also avoids repeatedly inserting/evaluating the same script (which could potentially cause problems) if it is within a containing element that you are inserting and then moving around the DOM.

The next thing is, I'll summarize what's the bad news by using .append() function to add a script.

And The Bad News is..

You can't debug your code.

I'm not joking, even if you add debugger; keyword between the line you want to set as breakpoint, you'll be end up getting only the call stack of the object without seeing the breakpoint on the source code, (not to mention that this keyword only works in webkit browser, all other major browsers seems to omit this keyword).

If you fully understand what your code does, than this will be a minor drawback. But if you don't, you will end up adding a debugger; keyword all over the place just to find out what's wrong with your (or my) code. Anyway, there's an alternative, don't forget that javascript can natively manipulate HTML DOM.

Workaround.

Use javascript (not jQuery) to manipulate HTML DOM

If you don't want to lose debugging capability, than you can use javascript native HTML DOM manipulation. Consider this example:

var script   = document.createElement("script");
script.type  = "text/javascript";
script.src   = "path/to/your/javascript.js";    // use this for linked script
script.text  = "alert('voila!');"               // use this for inline script
document.body.appendChild(script);

There it is, just like the old days isn't it. And don't forget to clean things up whether in the DOM or in the memory for all object that's referenced and not needed anymore to prevent memory leaks. You can consider this code to clean things up:

document.body.removechild(document.body.lastChild);
delete UnusedReferencedObjects; // replace UnusedReferencedObject with any object you created in the script you load.

The drawback from this workaround is that you may accidentally add a duplicate script, and that's bad. From here you can slightly mimic .append() function by adding an object verification before adding, and removing the script from the DOM right after it was added. Consider this example:

function AddScript(url, object){
    if (object != null){
        // add script
        var script   = document.createElement("script");
        script.type  = "text/javascript";
        script.src   = "path/to/your/javascript.js";
        document.body.appendChild(script);

        // remove from the dom
        document.body.removeChild(document.body.lastChild);
        return true;
    } else {
        return false;
    };
};

function DeleteObject(UnusedReferencedObjects) {
    delete UnusedReferencedObjects;
}

This way, you can add script with debugging capability while safe from script duplicity. This is just a prototype, you can expand for whatever you want it to be. I have been using this approach and quite satisfied with this. Sure enough I will never use jQuery .append() to add a script.

It may have been because I am still new to VS and definitely new to C, but the only thing that allowed me to build was adding

#pragma warning(disable:4996)

At the top of my file, this suppressed the C4996 error I was getting with sprintf

A bit annoying but perfect for my tiny bit of code and by far the easiest.

I read about it here: https://msdn.microsoft.com/en-us/library/2c8f766e.aspx

You might want to look here and here.

A Little code example from the first link:

<?php
// include the SOAP classes
require_once('nusoap.php');
// define parameter array (ISBN number)
$param = array('isbn'=>'0385503954');
// define path to server application
$serverpath ='http://services.xmethods.net:80/soap/servlet/rpcrouter';
//define method namespace
$namespace="urn:xmethods-BNPriceCheck";
// create client object
$client = new soapclient($serverpath);
// make the call
$price = $client->call('getPrice',$param,$namespace);
// if a fault occurred, output error info
if (isset($fault)) {
        print "Error: ". $fault;
        }
else if ($price == -1) {
        print "The book is not in the database.";
} else {
        // otherwise output the result
        print "The price of book number ". $param[isbn] ." is $". $price;
        }
// kill object
unset($client);
?>

I had various JDK from 1.5 to 1.7 installed on my PC. I had a need to learn JDK1.8 so installed and my earlier versions of Eclipse (depended on earlier versions of JDK) and I got errors launching my Eclipse IDE, on the command line I tried to check the Java Version and got the error below,

C:\>java -version
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.8', but '1.6' is required.
Error: could not find java.dll
Error: could not find Java SE Runtime Environment.

Solution:- I removed

C:\ProgramData\Oracle\Java\javapath;

You can use the re.sub() function to remove these characters:

>>> import re
>>> re.sub("[^a-zA-Z]+", "", "ABC12abc345def")
'ABCabcdef'

re.sub(MATCH PATTERN, REPLACE STRING, STRING TO SEARCH)

• "[^a-zA-Z]+" - look for any group of characters that are NOT a-zA-z.
• "" - Replace the matched characters with ""

I used to check $_POST until I got into a trouble with larger POST data and uploaded files. There are configuration directives post_max_size and upload_max_filesize - if any of them is exceeded, $_POST array is not populated.

So the "safe way" is to check $_SERVER['REQUEST_METHOD']. You still have to use isset() on every $_POST variable though, and it does not matter, whether you check or don't check $_SERVER['REQUEST_METHOD'].

Just remove the .value, like this:

function(arrayP){    
   for(var i = 0; i < arrayP.length; i++){
      alert(arrayP[i]);    //no .value here
   }
}

Sure you can pass an array, but to get the element at that position, use only arrayName[index], the .value would be getting the value property off an object at that position in the array - which for things like strings, numbers, etc doesn't exist. For example, "myString".value would also be undefined.
