For those of you looking for a solution for Oracle, I made a method from the code of Log4Jdbc. You will need to provide the query and the parameters passed to the preparedStatement since retrieving them from it is a bit of a pain:

private String generateActualSql(String sqlQuery, Object... parameters) {
    String[] parts = sqlQuery.split("\\?");
    StringBuilder sb = new StringBuilder();

    // This might be wrong if some '?' are used as litteral '?'
    for (int i = 0; i < parts.length; i++) {
        String part = parts[i];
        sb.append(part);
        if (i < parameters.length) {
            sb.append(formatParameter(parameters[i]));
        }
    }

    return sb.toString();
}

private String formatParameter(Object parameter) {
    if (parameter == null) {
        return "NULL";
    } else {
        if (parameter instanceof String) {
            return "'" + ((String) parameter).replace("'", "''") + "'";
        } else if (parameter instanceof Timestamp) {
            return "to_timestamp('" + new SimpleDateFormat("MM/dd/yyyy HH:mm:ss.SSS").
                    format(parameter) + "', 'mm/dd/yyyy hh24:mi:ss.ff3')";
        } else if (parameter instanceof Date) {
            return "to_date('" + new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").
                    format(parameter) + "', 'mm/dd/yyyy hh24:mi:ss')";
        } else if (parameter instanceof Boolean) {
            return ((Boolean) parameter).booleanValue() ? "1" : "0";
        } else {
            return parameter.toString();
        }
    }
}

Just to add to Jon's coding if you needed to take it a step further, and do more than just one column you can add something like

Dim copyRange2 As Range
Dim copyRange3 As Range

Set copyRange2 =src.Range("B2:B" & lastRow)
Set copyRange3 =src.Range("C2:C" & lastRow)

copyRange2.SpecialCells(xlCellTypeVisible).Copy tgt.Range("B12")
copyRange3.SpecialCells(xlCellTypeVisible).Copy tgt.Range("C12")

put these near the other codings that are the same you can easily change the Ranges as you need.

I only add this because it was helpful for me. I'd assume Jon already knows this but for those that are less experienced sometimes it's helpful to see how to change/add/modify these codings. I figured since Ruya didn't know how to manipulate the original coding it could be helpful if one ever needed to copy over only 2 visibile columns, or only 3, etc. You can use this same coding, add in extra lines that are almost the same and then the coding is copying over whatever you need.

I don't have enough reputation to reply to Jon's comment directly so I have to post as a new comment, sorry.

Try using COUNT function like this

=IF(COUNT(SEARCH({"Romney","Obama","Gingrich"},C1)),1,"")

Note that you don't need the wildcards (as teylyn says) and unless there's a specific reason "1" doesn't need quotes (in fact that makes it a text value)

If the script only defines the functions and does nothing else, you can first execute the script within the context of the current shell using the source or . command and then simply call the function. See help source for more information.

Found tar -cvf site1-$seqNumber.tar -C /var/www/ site1 as more friendlier solution than tar -cvf site1-$seqNumber.tar -C /var/www/site1 . (notice the . in the second solution) for the following reasons

• Tar file name can be insignificant as the original folder is now an archive entry
• Tar file name being insignificant to the content can now be used for other purposes like sequence numbers, periodical backup etc.

Surprisingly, all 10 answers here say the same thing. The '::' is a namespace resolution operator, and yes it is true. But there is one gotcha that you have to realize about the namespace resolution operator when it comes to the constant lookup algorithm. As Matz delineates in his book, 'The Ruby Programming Language', constant lookup has multiple steps. First, it searches a constant in the lexical scope where the constant is referenced. If it does not find the constant within the lexical scope, it then searches the inheritance hierarchy. Because of this constant lookup algorithm, below we get the expected results:

module A
  module B
      PI = 3.14
      module C
        class E
          PI = 3.15
        end
        class F < E
          def get_pi
            puts PI
          end
        end
      end
  end
end
f = A::B::C::F.new
f.get_pi
> 3.14

While F inherits from E, the B module is within the lexical scope of F. Consequently, F instances will refer to the constant PI defined in the module B. Now if module B did not define PI, then F instances will refer to the PI constant defined in the superclass E.

But what if we were to use '::' rather than nesting modules? Would we get the same result? No!

By using the namespace resolution operator when defining nested modules, the nested modules and classes are no longer within the lexical scope of their outer modules. As you can see below, PI defined in A::B is not in the lexical scope of A::B::C::D and thus we get uninitialized constant when trying to refer to PI in the get_pi instance method:

module A
end

module A::B
  PI = 3.14
end

module A::B::C
  class D
    def get_pi
      puts PI
    end
  end
end
d = A::B::C::D.new
d.get_pi
NameError: uninitialized constant A::B::C::D::PI
Did you mean?  A::B::PI

See the documentation for the print function: print()

The content of end is printed after the thing you want to print. By default it contains a newline ("\n") but it can be changed to something else, like an empty string.

Query below should help you achieve what you want.

select scountry, headofstate from data 
where data.scountry like 'a%'and ttlppl>=100000

You have a JSON string, not an object. Tell jQuery that you expect a JSON response and it will parse it for you. Either use $.getJSON instead of $.get, or pass the dataType argument to $.get:

$.get(
    'index.php?r=admin/post/ajax',
    {"parentCatId":parentCatId},
    function(data){                     
        $.each(data, function(key, value){
            console.log(key + ":" + value)
        })
    },
    'json'
);

I've found this to work:

var element1 = document.createElement("input");
element1.type = "hidden";
element1.value = "10";
element1.name = "a";
document.getElementById("chells").appendChild(element1);

Here's CodeIgniter's implementation.

/**
 * Sanitize Filename
 *
 * @param   string  $str        Input file name
 * @param   bool    $relative_path  Whether to preserve paths
 * @return  string
 */
public function sanitize_filename($str, $relative_path = FALSE)
{
    $bad = array(
        '../', '<!--', '-->', '<', '>',
        "'", '"', '&', '$', '#',
        '{', '}', '[', ']', '=',
        ';', '?', '%20', '%22',
        '%3c',      // <
        '%253c',    // <
        '%3e',      // >
        '%0e',      // >
        '%28',      // (
        '%29',      // )
        '%2528',    // (
        '%26',      // &
        '%24',      // $
        '%3f',      // ?
        '%3b',      // ;
        '%3d'       // =
    );

    if ( ! $relative_path)
    {
        $bad[] = './';
        $bad[] = '/';
    }

    $str = remove_invisible_characters($str, FALSE);
    return stripslashes(str_replace($bad, '', $str));
}

And the remove_invisible_characters dependency.

function remove_invisible_characters($str, $url_encoded = TRUE)
{
    $non_displayables = array();

    // every control character except newline (dec 10),
    // carriage return (dec 13) and horizontal tab (dec 09)
    if ($url_encoded)
    {
        $non_displayables[] = '/%0[0-8bcef]/';  // url encoded 00-08, 11, 12, 14, 15
        $non_displayables[] = '/%1[0-9a-f]/';   // url encoded 16-31
    }

    $non_displayables[] = '/[\x00-\x08\x0B\x0C\x0E-\x1F\x7F]+/S';   // 00-08, 11, 12, 14-31, 127

    do
    {
        $str = preg_replace($non_displayables, '', $str, -1, $count);
    }
    while ($count);

    return $str;
}

Most of these linker errors occur because of missing libraries.

I added the libstdc++.6.dylib in my Project->Targets->Build Phases-> Link Binary With Libraries.

That solved it for me on Xcode 6.3.2 for iOS 8.3

Cheers!

Please see Why does the property I want to mock need to be virtual?

You may have to write a wrapper interface or mark the property as virtual/abstract as Moq creates a proxy class that it uses to intercept calls and return your custom values that you put in the .Returns(x) call.

The above answers are wrong, respectively aren't answering why you're having troubles viewing the demo-content prod-mode.

Here's the correct answer: clear your "prod"-cache:

php app/console cache:clear --env prod

If anyone else stumbles onto this page from google like I did:

use putty (putty.exe) to sign into your server and install curl using this command :

    sudo apt-get install php5-curl

Make sure curl is enabled in the php.ini file. For me it's in /etc/php5/apache2/php.ini, if you can't find it, this line might be in /etc/php5/conf.d/curl.ini. Make sure the line :

    extension=curl.so

is not commented out then restart apache, so type this into putty:

    sudo /etc/init.d/apache2 restart

Info for install from https://askubuntu.com/questions/9293/how-do-i-install-curl-in-php5, to check if it works this stack overflow might help you: Detect if cURL works?

I'd really recommend Scrapy.

Quote from a deleted answer:

• Scrapy crawling is fastest than mechanize because uses asynchronous operations (on top of Twisted).
• Scrapy has better and fastest support for parsing (x)html on top of libxml2.
• Scrapy is a mature framework with full unicode, handles redirections, gzipped responses, odd encodings, integrated http cache, etc.
• Once you are into Scrapy, you can write a spider in less than 5 minutes that download images, creates thumbnails and export the extracted data directly to csv or json.

showInventory(player);     // I get the error here.

void showInventory(player& obj) {   // By Johnny :D

this means that player is an datatype and showInventory expect an referance to an variable of type player.

so the correct code will be

  void showInventory(player& obj) {   // By Johnny :D
    for(int i = 0; i < 20; i++) {
        std::cout << "\nINVENTORY:\n" + obj.getItem(i);
        i++;
        std::cout << "\t\t\t" + obj.getItem(i) + "\n";
        i++;
    }
    }

players myPlayers[10];

    std::string toDo() //BY KEATON
    {
    std::string commands[5] =   // This is the valid list of commands.
        {"help", "inv"};

    std::string ans;
    std::cout << "\nWhat do you wish to do?\n>> ";
    std::cin >> ans;

    if(ans == commands[0]) {
        helpMenu();
        return NULL;
    }
    else if(ans == commands[1]) {
        showInventory(myPlayers[0]);     // or any other index,also is not necessary to have an array
        return NULL;
    }

}

My manual workaround, which involves manually updating model.options when a new radio button is selected:

template: `
  <label *ngFor="let item of radioItems">
    <input type="radio" name="options" (click)="model.options = item" 
     [checked]="item === model.options">
    {{item}}
  </label>`

class App {
  radioItems = 'one two three'.split(' ');
  model      = { options: 'two' };
}

This Plunker demonstrates the above, as well as how to use a button to change the selected radio button -- i.e., to prove that the data binding is two-way:

<button (click)="model.options = 'one'">set one</button>

UPDATE: This question was the subject of my blog on May 12th 2011. Thanks for the great question!

Suppose you have an interface as you describe, and a hundred classes that implement it. Then you decide to make one of the parameters of one of the interface's methods optional. Are you suggesting that the right thing to do is for the compiler to force the developer to find every implementation of that interface method, and make the parameter optional as well?

Suppose we did that. Now suppose the developer did not have the source code for the implementation:

// in metadata:
public class B 
{ 
    public void TestMethod(bool b) {}
}

// in source code
interface MyInterface 
{ 
    void TestMethod(bool b = false); 
}
class D : B, MyInterface {}
// Legal because D's base class has a public method 
// that implements the interface method

How is the author of D supposed to make this work? Are they required in your world to call up the author of B on the phone and ask them to please ship them a new version of B that makes the method have an optional parameter?

That's not going to fly. What if two people call up the author of B, and one of them wants the default to be true and one of them wants it to be false? What if the author of B simply refuses to play along?

Perhaps in that case they would be required to say:

class D : B, MyInterface 
{
    public new void TestMethod(bool b = false)
    {
        base.TestMethod(b);
    }
}

The proposed feature seems to add a lot of inconvenience for the programmer with no corresponding increase in representative power. What's the compelling benefit of this feature which justifies the increased cost to the user?

UPDATE: In the comments below, supercat suggests a language feature that would genuinely add power to the language and enable some scenarios similar to the one described in this question. FYI, that feature -- default implementations of methods in interfaces -- will be added to C# 8.

There are right answers but I just want to add one more option (requires downtime):

1. Stop Redis.
2. Delete RDB file (find location in redis.conf).
3. Start Redis.

Swift 4:

I was having an issue with the most accepted answer, in which hiding the keyboard did not return the view all the way to the bottom of the page (only partially). This worked for me (+updated for Swift 4).

override func viewDidLoad() {
    super.viewDidLoad()
    self.hideKeyboardWhenTappedAround()
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: NSNotification.Name.UIKeyboardWillHide, object: nil)
}

@objc func keyboardWillShow(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y == 0{
            self.view.frame.origin.y -= keyboardSize.height
        }
    }
}

@objc func keyboardWillHide(notification: NSNotification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        if self.view.frame.origin.y != 0{
            self.view.frame.origin.y = 0
        }
    }
}

In case you want to use bootstrap radio to check one of them depends on the result of your checked var in the .ts file.

component.html

<h1>Radio Group #1</h1>
<div class="btn-group btn-group-toggle" data-toggle="buttons" >
   <label [ngClass]="checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio1" value="option1" type="radio"> TRUE
   </label>
   <label [ngClass]="!checked ? 'active' : ''" class="btn btn-outline-secondary">
     <input name="radio" id="radio2" value="option2" type="radio"> FALSE
   </label>
</div>

component.ts file

@Component({
  selector: '',
  templateUrl: './.component.html',
  styleUrls: ['./.component.css']
})
export class radioComponent implements OnInit {
  checked = true;
}

To Solve this Error in Webview Android, First Check the Permissions in Manifest.xml, if not define there,then define as like this. <uses-permission android:name="android.permission.INTERNET"/>

Tests

On the Tests class we will add an @XmlRootElement annotation. Doing this will let your JAXB implementation know that when a document starts with this element that it should instantiate this class. JAXB is configuration by exception, this means you only need to add annotations where your mapping differs from the default. Since the testData property differs from the default mapping we will use the @XmlElement annotation. You may find the following tutorial helpful: http://wiki.eclipse.org/EclipseLink/Examples/MOXy/GettingStarted

package forum11221136;

import javax.xml.bind.annotation.*;

@XmlRootElement
public class Tests {

    TestData testData;

    @XmlElement(name="test-data")
    public TestData getTestData() {
        return testData;
    }

    public void setTestData(TestData testData) {
        this.testData = testData;
    }

}

TestData

On this class I used the @XmlType annotation to specify the order in which the elements should be ordered in. I added a testData property that appeared to be missing. I also used an @XmlElement annotation for the same reason as in the Tests class.

package forum11221136;

import java.util.List;
import javax.xml.bind.annotation.*;

@XmlType(propOrder={"title", "book", "count", "testData"})
public class TestData {
    String title;
    String book;
    String count;
    List<TestData> testData;

    public String getTitle() {
        return title;
    }
    public void setTitle(String title) {
        this.title = title;
    }
    public String getBook() {
        return book;
    }
    public void setBook(String book) {
        this.book = book;
    }
    public String getCount() {
        return count;
    }
    public void setCount(String count) {
        this.count = count;
    }
    @XmlElement(name="test-data")
    public List<TestData> getTestData() {
        return testData;
    }
    public void setTestData(List<TestData> testData) {
        this.testData = testData;
    }
}

Demo

Below is an example of how to use the JAXB APIs to read (unmarshal) the XML and populate your domain model and then write (marshal) the result back to XML.

package forum11221136;

import java.io.File;
import javax.xml.bind.*;

public class Demo {

    public static void main(String[] args) throws Exception {
        JAXBContext jc = JAXBContext.newInstance(Tests.class);

        Unmarshaller unmarshaller = jc.createUnmarshaller();
        File xml = new File("src/forum11221136/input.xml");
        Tests tests = (Tests) unmarshaller.unmarshal(xml);

        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        marshaller.marshal(tests, System.out);
    }

}

On the flip side, I was having an issue with PHPUNIT asserting urls was contained in or equal to a url that was json_encoded -

my expected:

http://localhost/api/v1/admin/logs/testLog.log

would be encoded to:

http:\/\/localhost\/api\/v1\/admin\/logs\/testLog.log

If you need to do a comparison, transforming the url using:

addcslashes($url, '/')

allowed for the proper output during my comparisons.

At first I would use http://ruby.railstutorial.org/.

And database.yml is place where you put setup for database your application use - username, password, host - for each database. With new application you dont need to change anything - simply use default sqlite setup.

there's no problem - everything works as expected.

In GitLab some branches can be protected. By default only Maintainer/Owner users can commit to protected branches (see permissions docs). master branch is protected by default - it forces developers to issue merge requests to be validated by project maintainers before integrating them into main code.

You can turn on and off protection on selected branches in Project Settings (where exactly depends on GitLab version - see instructions below).

On the same settings page you can also allow developers to push into the protected branches. With this setting on, protection will be limited to rejecting operations requiring git push --force (rebase etc.)

Since GitLab 9.3

Go to project: "Settings" ? "Repository" ? "Expand" on "Protected branches"

I'm not really sure when this change was introduced, screenshots are from 10.3 version.

Now you can select who is allowed to merge or push into selected branches (for example: you can turn off pushes to master at all, forcing all changes to branch to be made via Merge Requests). Or you can click "Unprotect" to completely remove protection from branch.

Since GitLab 9.0

Similarly to GitLab 9.3, but no need to click "Expand" - everything is already expanded:

Go to project: "Settings" ? "Repository" ? scroll down to "Protected branches".

Pre GitLab 9.0

Project: "Settings" ? "Protected branches" (if you are at least 'Master' of given project).

Then click on "Unprotect" or "Developers can push":

public ActionResult GetAjaxValue()
{
   return Content("string value");
}

In C#, you can write

(long)(date - new DateTime(1970, 1, 1)).TotalMilliseconds

In the following code:

def f(x) -> int:
    return int(x)

the -> int just tells that f() returns an integer (but it doesn't force the function to return an integer). It is called a return annotation, and can be accessed as f.__annotations__['return'].

Python also supports parameter annotations:

def f(x: float) -> int:
    return int(x)

: float tells people who read the program (and some third-party libraries/programs, e. g. pylint) that x should be a float. It is accessed as f.__annotations__['x'], and doesn't have any meaning by itself. See the documentation for more information:

https://docs.python.org/3/reference/compound_stmts.html#function-definitions https://www.python.org/dev/peps/pep-3107/

You can't create an array immediately because you need to know the number of rows from the beginning (and this would require to read the csv file twice)

You can store values in two List<T> and then use them or convert into an array using List<T>.ToArray()

Very simple example:

var column1 = new List<string>();
var column2 = new List<string>();
using (var rd = new StreamReader("filename.csv"))
{
    while (!rd.EndOfStream)
    {
        var splits = rd.ReadLine().Split(';');
        column1.Add(splits[0]);
        column2.Add(splits[1]);
    }
}
// print column1
Console.WriteLine("Column 1:");
foreach (var element in column1)
    Console.WriteLine(element);

// print column2
Console.WriteLine("Column 2:");
foreach (var element in column2)
    Console.WriteLine(element);

N.B.

Please note that this is just a very simple example. Using string.Split does not account for cases where some records contain the separator ; inside it.
For a safer approach, consider using some csv specific libraries like CsvHelper on nuget.

GUID algorithms are usually implemented according to the v4 GUID specification, which is essentially a pseudo-random string. Sadly, these fall into the category of "likely non-unique", from Wikipedia (I don't know why so many people ignore this bit): "... other GUID versions have different uniqueness properties and probabilities, ranging from guaranteed uniqueness to likely non-uniqueness."

The pseudo-random properties of V8's JavaScript Math.random() are TERRIBLE at uniqueness, with collisions often coming after only a few thousand iterations, but V8 isn't the only culprit. I've seen real-world GUID collisions using both PHP and Ruby implementations of v4 GUIDs.

Because it's becoming more and more common to scale ID generation across multiple clients, and clusters of servers, entropy takes a big hit -- the chances of the same random seed being used to generate an ID escalate (time is often used as a random seed in pseudo-random generators), and GUID collisions escalate from "likely non-unique" to "very likely to cause lots of trouble".

To solve this problem, I set out to create an ID algorithm that could scale safely, and make better guarantees against collision. It does so by using the timestamp, an in-memory client counter, client fingerprint, and random characters. The combination of factors creates an additive complexity that is particularly resistant to collision, even if you scale it across a number of hosts:

http://usecuid.org/

To go to location WITH PIN on it, use:

String uri = "http://maps.google.com/maps?q=loc:" + destinationLatitude + "," + destinationLongitude;
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
intent.setPackage("com.google.android.apps.maps");
startActivity(intent);

for without pin, use this in uri:

 String uri = "geo:" + destinationLatitude + "," + destinationLongitude;

If your path environment variable contains Python (eg. C:\Python27\) you can run your py file simply from Windows command line (cmd). Howto here.

I was basically facing the same issue. I deleted the BIN folder, then removed unused jar files for Order and Import from eclipse. IT WORKED after that

  .Where(e => e.Value.StartsWith("BALTIMORE"))

This works like "LIKE" of SQL...

To switch to a popup window, you need to use getWindowHandles() and iterate through them.

In your code you are using getWindowHandle() which will give you the parent window itself.

String parentWindowHandler = driver.getWindowHandle(); // Store your parent window
String subWindowHandler = null;

Set<String> handles = driver.getWindowHandles(); // get all window handles
Iterator<String> iterator = handles.iterator();
while (iterator.hasNext()){
    subWindowHandler = iterator.next();
}
driver.switchTo().window(subWindowHandler); // switch to popup window

// Now you are in the popup window, perform necessary actions here

driver.switchTo().window(parentWindowHandler);  // switch back to parent window

Thus this tag is used to future proof the webpage, such that the older / compatible engine is used to render it the same way as intended by the creator.

Make sure that you have checked it to work properly with the IE version you specify.

ORA-12154: TNS:could not resolve the connect identifier specified?

In case the TNS is not defined you can also try this one:

If you are using C#.net 2010 or other version of VS and oracle 10g express edition or lower version, and you make a connection string like this:

static string constr = @"Data Source=(DESCRIPTION=
    (ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=yourhostname )(PORT=1521)))
    (CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));
    User Id=system ;Password=yourpasswrd"; 

After that you get error message ORA-12154: TNS:could not resolve the connect identifier specified then first you have to do restart your system and run your project.

And if Your windows is 64 bit then you need to install oracle 11g 32 bit and if you installed 11g 64 bit then you need to Install Oracle 11g Oracle Data Access Components (ODAC) with Oracle Developer Tools for Visual Studio version 11.2.0.1.2 or later from OTN and check it in Oracle Universal Installer Please be sure that the following are checked:

Oracle Data Provider for .NET 2.0

Oracle Providers for ASP.NET

Oracle Developer Tools for Visual Studio

Oracle Instant Client 

And then restart your Visual Studio and then run your project .... NOTE:- SYSTEM RESTART IS necessary TO SOLVE THIS TYPES OF ERROR.......

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

you can add this style to your buttons:

#button1 , #button2 {
display:inline-block;
/* additional code */
}

import java.util.Scanner;

class CalculateGCD 
{   
  public static int calGCD(int a, int b) 
  { 
   int c=0,d=0;  
   if(a>b){c=b;} 
   else{c=a;}  
   for(int i=c; i>0; i--) 
   { 
    if(((a%i)+(b%i))==0) 
    { 
     d=i; 
     break; 
    } 
   } 
   return d;  
  }  

  public static void main(String args[]) 
  { 
   Scanner sc=new Scanner(System.in); 
   System.out.println("Enter the nos whose GCD is to be calculated:"); 
   int a=sc.nextInt(); 
   int b=sc.nextInt(); 
   System.out.println(calGCD(a,b));  
  } 
 } 

I guess you mean this:

class Value:
    def __init__(self, v=None):
        self.v = v

v1 = Value(1)
v2 = Value(2)

d = {'a': v1, 'b': v1, 'c': v2, 'd': v2}
d['a'].v += 1

d['b'].v == 2 # True

• Python's strings and numbers are immutable objects,
• So, if you want d['a'] and d['b'] to point to the same value that "updates" as it changes, make the value refer to a mutable object (user-defined class like above, or a dict, list, set).
• Then, when you modify the object at d['a'], d['b'] changes at same time because they both point to same object.

Run this Command

Might be cleaner to use PrintWriter and its method println.
Just make sure you close the writer when you're done

Pretty neat with seaborn for Python users:

       dialog.setContentView(R.layout.list)

ListView lv = (ListView ) dialog.findViewById(R.id.lv);
dialog.setCancelable(true);
dialog.setTitle("ListView");

Snap

I use this one:

LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)

For example, using a 1s interval:

locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);

the time is in milliseconds, the distance is in meters.

This automatically calls:

public void onLocationChanged(Location location) {
    //Code here, location.getAccuracy(), location.getLongitude() etc...
}

I also had these included in the script but didnt actually use them:

public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}

In short:

public class GPSClass implements LocationListener {

    public void onLocationChanged(Location location) {
        // Called when a new location is found by the network location provider.
        Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
    }

    public void onStatusChanged(String provider, int status, Bundle extras) {}
    public void onProviderEnabled(String provider) {}
    public void onProviderDisabled(String provider) {}

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
    }
}

You need to use the command echo $PATH to display the PATH variable or you can just execute set or env to display all of your environment variables.

By typing $PATH you tried to run your PATH variable contents as a command name.

Bash displayed the contents of your path any way. Based on your output the following directories will be searched in the following order:

/usr/local/share/npm/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin

Had a similar problem, but in Windows. I was trying to figure out how to open a large MySql sql file in Windows, and these are the steps I had to take:

• Go to the download website (http://dev.mysql.com/downloads/).
• Download the MySQL Community Server and install it (select the developer or full install, so it will install client and server tools).
• Open MySql Command Line Client from the Start menu.
• Enter your password used in install.

• In the prompt, mysql>, enter:

  CREATE DATABASE database_name;

  USE database_name;

  SOURCE myfile.sql

That should import your large file.

Place it in your bash profile:

~/.bash_profile

Use the index to get desired node if xpath is complicated or more than one node present with same xpath.

Ex :

You can give the number which node you want.

It's because you have turned on USB debugging in Developer Options. You can create a bug report by holding the power + both volume up and down.

Edit: This is what the forums say:

By pressing Volume up + Volume down + power button, you will feel a vibration after a second or so, that's when the bug reporting initiated.

To disable:

/system/bin/bugmailer.sh must be deleted/renamed.

There should be a folder on your SD card called "bug reports".

The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.

The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?

try:

dt <- data.table(A = c(1:5), 
                 B= c(11:15))

x <- ncol(dt)

for(i in 1:x) 
{
     dt[[i]] <- as.character(dt[[i]])
}

Your solution is correct, but there is some redundancy in your regex.
The similar result can also be obtained from the following regex:

^([A-Z]{3})$

The {3} indicates that the [A-Z] must appear exactly 3 times.

Note, the localhost is a special string that FB allows here. If you didn't configure your debugging environment under localhost, you'll have to push it underneath that name as far as I can tell.

Note that starting Python 3.8, the standard library provides the math.comb function to compute the binomial coefficient:

math.comb(n, k)

which is the number of ways to choose k items from n items without repetition
n! / (k! (n - k)!):

import math
math.comb(10, 5)  # 252
math.comb(10, 10) # 1

Just in case anyone got to a desperate point where nothing works... It happened to us that the content assist somehow shrunk so no suggestion was shown, just the "Press Ctrl+Space for non-Java..." could be seen. So, it was just a matter of dragging the corner of the content assist to enlarge the pop-up.

I know, embarrassing. Hope it helps.

As Sagi stated in their answer DataTable.Load is a good solution. If you are trying to load multiple tables from a single reader you do not need to call DataReader.NextResult. The DataTable.Load method also advances the reader to the next result set (if any).

// Read every result set in the data reader.
while (!reader.IsClosed)
{
    DataTable dt = new DataTable();
    // DataTable.Load automatically advances the reader to the next result set
    dt.Load(reader);
    items.Add(dt);
}

    <?php
if (isset($_POST['birthdate'])) {
    $timestamp = strtotime($_POST['birthdate']); 
    $date=date('d',$timestamp);
    $month=date('m',$timestamp);
    $year=date('Y',$timestamp);
}
?>  

Try this:

var data = jQuery.parseJSON(response);
$.each(data, function(key, item) 
{
   console.log(item.com);
});

or

var data = $.parseJSON(response);

$(data).each(function(i,val)
 {
    $.each(val,function(key,val)
  {
          console.log(key + " : " + val);     
  });
});

To get individual colour values you can use Color like following for pixel(x,y).

import java.awt.Color;
import java.awt.image.BufferedImage;

Color c = new Color(buffOriginalImage.getRGB(x,y));
int red = c.getRed();
int green = c.getGreen();
int blue = c.getBlue();

The above will give you the integer values of Red, Green and Blue in range of 0 to 255.

To set the values from RGB you can do so by:

Color myColour = new Color(red, green, blue);
int rgb = myColour.getRGB();

//Change the pixel at (x,y) ti rgb value
image.setRGB(x, y, rgb);

Please be advised that the above changes the value of a single pixel. So if you need to change the value entire image you may need to iterate over the image using two for loops.

You can use getChanges() on Eloquent model even after persisting.

The generic wildcards target two primary needs:

Reading from a generic collection Inserting into a generic collection There are three ways to define a collection (variable) using generic wildcards. These are:

List<?>           listUknown = new ArrayList<A>();
List<? extends A> listUknown = new ArrayList<A>();
List<? super   A> listUknown = new ArrayList<A>();

List<?> means a list typed to an unknown type. This could be a List<A>, a List<B>, a List<String> etc.

List<? extends A> means a List of objects that are instances of the class A, or subclasses of A (e.g. B and C). List<? super A> means that the list is typed to either the A class, or a superclass of A.

If you're interested in Unit-Tests, then you can declare a public "ToStringTemplate", and then you can unit test your toString. Even if you don't unit-test it, I think its "cleaner" and uses String.format.

public class Kid {

    public static final String ToStringTemplate = "KidName='%1s', Height='%2s', GregCalendar='%3s'";

    private String kidName;
    private double height;
    private GregorianCalendar gregCalendar;

    public String getKidName() {
        return kidName;
    }

    public void setKidName(String kidName) {
        this.kidName = kidName;
    }

    public double getHeight() {
        return height;
    }

    public void setHeight(double height) {
        this.height = height;
    }

    public GregorianCalendar getGregCalendar() {
        return gregCalendar;
    }

    public void setGregCalendar(GregorianCalendar gregCalendar) {
        this.gregCalendar = gregCalendar;
    }

    public String toString() { 
        return String.format(ToStringTemplate, this.getKidName(), this.getHeight(), this.getGregCalendar());
    } 
}

Now you can unit test by create the Kid, setting the properties, and doing your own string.format on the ToStringTemplate and comparing.

making ToStringTemplate static-final means "ONE VERSION" of the truth, rather than having a "copy" of the template in the unit-test.

The SimpleDateFormat class has a method called SetTimeZone(TimeZone) that is inherited from the DateFormat class. http://docs.oracle.com/javase/6/docs/api/java/text/DateFormat.html

I've used this creating an IFrame through Javascript and it worked for me:

// IFrame points to the IFrame element, obviously
IFrame.src = 'about: blank';
IFrame.style.backgroundColor = "transparent";
IFrame.frameBorder = "0";
IFrame.allowTransparency="true";

Not sure if it makes any difference, but I set those properties before adding the IFrame to the DOM. After adding it to the DOM, I set its src to the real URL.

I keep on forgetting this and coming back to it again! I think the best answer is a combination of the responses provided so far.

Firstly, & is the variable prefix in sqlplus/sqldeveloper, hence the problem - when it appears, it is expected to be part of a variable name.

SET DEFINE OFF will stop sqlplus interpreting & this way.

But what if you need to use sqlplus variables and literal & characters?

• You need SET DEFINE ON to make variables work
• And SET ESCAPE ON to escape uses of &.

e.g.

set define on
set escape on

define myvar=/forth

select 'back\\ \& &myvar' as swing from dual;

Produces:

old   1: select 'back\\ \& &myvar' from dual
new   1: select 'back\ & /forth' from dual

SWING
--------------
back\ & /forth

If you want to use a different escape character:

set define on
set escape '#'

define myvar=/forth

select 'back\ #& &myvar' as swing from dual;

When you set a specific escape character, you may see 'SP2-0272: escape character cannot be alphanumeric or whitespace'. This probably means you already have the escape character defined, and things get horribly self-referential. The clean way of avoiding this problem is to set escape off first:

set escape off
set escape '#'

For dynamic SQL use:

'IN(' ||array_to_string(some_array, ',')||')'

Example

DO LANGUAGE PLPGSQL $$

DECLARE
    some_array bigint[];
    sql_statement text;

BEGIN

    SELECT array[1, 2] INTO some_array;
    RAISE NOTICE '%', some_array;

    sql_statement := 'SELECT * FROM my_table WHERE my_column IN(' ||array_to_string(some_array, ',')||')';
    RAISE NOTICE '%', sql_statement;

END;

$$;

Result: NOTICE: {1,2} NOTICE: SELECT * FROM my_table WHERE my_column IN(1,2)

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

You can use this command (python script) for larger inputs:

echo 58595a | python -c "import sys; import binascii; print(binascii.unhexlify(sys.stdin.read().strip()).decode())"

The result will be:

XYZ

And for more simplicity, define an alias:

alias hexdecoder='python -c "import sys; import binascii; print(binascii.unhexlify(sys.stdin.read().strip()).decode())"'

echo 58595a | hexdecoder

To permanently set the language syntax:
open settings.json file

*) format all txt files with javascript formatting

"files.associations": {
        "*.txt": "javascript"

 }

*) format all unsaved files (untitled-1 etc) to javascript:

"files.associations": {
        "untitled-*": "javascript"

 }

Use inspect.getmembers to get all the variables/classes/functions etc. in a module, and pass in inspect.isfunction as the predicate to get just the functions:

from inspect import getmembers, isfunction
from my_project import my_module

functions_list = [o for o in getmembers(my_module) if isfunction(o[1])]

getmembers returns a list of (object_name, object) tuples sorted alphabetically by name.

You can replace isfunction with any of the other isXXX functions in the inspect module.

I've experienced "internal errors" in the .NET runtime that turned out to be caused by bugs in my code; don't think that just because it was an "internal error" in the .NET runtime that there isn't a bug in your code as the root cause. Always always always blame your own code before you blame someone else's.

Hopefully you have logging and exception/stack trace information to point you where to start looking, or that you can repeat the state of the system before the crash.

You might actually look into the internationally standardized format E.164, recommended by Twilio for example (who have a service and an API for sending SMS or phone-calls via REST requests).

This is likely to be the most universal way to store phone numbers, in particular if you have international numbers work with.

1. Phone by PhoneNumberField

You can use phonenumber_field library. It is port of Google's libphonenumber library, which powers Android's phone number handling https://github.com/stefanfoulis/django-phonenumber-field

In model:

from phonenumber_field.modelfields import PhoneNumberField

class Client(models.Model, Importable):
    phone = PhoneNumberField(null=False, blank=False, unique=True)

In form:

from phonenumber_field.formfields import PhoneNumberField
class ClientForm(forms.Form):
    phone = PhoneNumberField()

Get phone as string from object field:

    client.phone.as_e164 

Normolize phone string (for tests and other staff):

    from phonenumber_field.phonenumber import PhoneNumber
    phone = PhoneNumber.from_string(phone_number=raw_phone, region='RU').as_e164

2. Phone by regexp

One note for your model: E.164 numbers have a max character length of 15.

To validate, you can employ some combination of formatting and then attempting to contact the number immediately to verify.

I believe I used something like the following on my django project:

class ReceiverForm(forms.ModelForm):
    phone_number = forms.RegexField(regex=r'^\+?1?\d{9,15}$', 
                                error_message = ("Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed."))

EDIT

It appears that this post has been useful to some folks, and it seems worth it to integrate the comment below into a more full-fledged answer. As per jpotter6, you can do something like the following on your models as well:

models.py:

from django.core.validators import RegexValidator

class PhoneModel(models.Model):
    ...
    phone_regex = RegexValidator(regex=r'^\+?1?\d{9,15}$', message="Phone number must be entered in the format: '+999999999'. Up to 15 digits allowed.")
    phone_number = models.CharField(validators=[phone_regex], max_length=17, blank=True) # validators should be a list

Update Aug 2020

Although the below is still worth reading for the useful info, we have had Flexbox for some time now, so just use that, as per this answer.

You can't use:

vertical-align:middle because it's not applicable to block-level elements

margin-top:auto and margin-bottom:auto because their used values would compute as zero

margin-top:-50% because percentage-based margin values are calculated relative to the width of containing block

In fact, the nature of document flow and element height calculation algorithms make it impossible to use margins for centering an element vertically inside its parent. Whenever a vertical margin's value is changed, it will trigger a parent element height re-calculation (re-flow), which would in turn trigger a re-center of the original element... making it an infinite loop.

You can use:

A few workarounds like this which work for your scenario; the three elements have to be nested like so:

.container {
    display: table;
    height: 100%;
    position: absolute;
    overflow: hidden;
    width: 100%;
}
.helper {
    #position: absolute;
    #top: 50%;
    display: table-cell;
    vertical-align: middle;
}
.content {
    #position: relative;
    #top: -50%;
    margin: 0 auto;
    width: 200px;
    border: 1px solid orange;
}

<div class="container">
    <div class="helper">
        <div class="content">
            <p>stuff</p>
        </div>
    </div>
</div

JSFiddle works fine according to Browsershot.

I got this problem while using Bootstrap and I had multiple columns in each rows.

I was trying to give page-break-inside: avoid; or break-inside: avoid; to the col-md-6 div elements. That was not working.

I took a hint from the answers given above by DOK that floating elements do not work well with page-break-inside: avoid;.

Instead, I had to give page-break-inside: avoid; or break-inside: avoid; to the <div class="row"> element. And I had multiple rows in my print page.

That is, each row only had 2 columns in it. And they always fit horizontally and do not wrap on a new line.

In another example case, if you want 4 columns in each row, then use col-md-3.

You can use python within the bash script too. I didn't have much success with some of the top answers here, and found this to work without the need for loops:

#!/bin/bash
python
filetosearch = '/home/ubuntu/ip_table.txt'
texttoreplace = 'tcp443'
texttoinsert = 'udp1194'

s = open(filetosearch).read()
s = s.replace(texttoreplace, texttoinsert)
f = open(filetosearch, 'w')
f.write(s)
f.close()
quit()

I know this is a couple of years late, but this is the 3rd Google response now for "Tkinter hide Label" as of 10/27/13... So if anyone like myself a few weeks ago is building a simple GUI and just wants some text to appear without swapping it out for another widget via "lower" or "lift" methods, I'd like to offer a workaround I use (Python2.7,Windows):

from Tkinter import *


class Top(Toplevel):
    def __init__(self, parent, title = "How to Cheat and Hide Text"):
        Toplevel.__init__(self,parent)
        parent.geometry("250x250+100+150")
        if title:
            self.title(title)
        parent.withdraw()
        self.parent = parent
        self.result = None
        dialog = Frame(self)
        self.initial_focus = self.dialog(dialog)
        dialog.pack()


    def dialog(self,parent):

        self.parent = parent

        self.L1 = Label(parent,text = "Hello, World!",state = DISABLED, disabledforeground = parent.cget('bg'))
        self.L1.pack()

        self.B1 = Button(parent, text = "Are You Alive???", command = self.hello)
        self.B1.pack()

    def hello(self):
        self.L1['state']="normal"


if __name__ == '__main__':
    root=Tk()   
    ds = Top(root)
    root.mainloop()

The idea here is that you can set the color of the DISABLED text to the background ('bg') of the parent using ".cget('bg')" http://effbot.org/tkinterbook/widget.htm rendering it "invisible". The button callback resets the Label to the default foreground color and the text is once again visible.

Downsides here are that you still have to allocate the space for the text even though you can't read it, and at least on my computer, the text doesn't perfectly blend to the background. Maybe with some tweaking the color thing could be better and for compact GUIs, blank space allocation shouldn't be too much of a hassle for a short blurb.

See Default window colour Tkinter and hex colour codes for the info about how I found out about the color stuff.

This is an old thread, but I have just encountered this situation and discovered a neat way around it. I was trying to run a setup.exe, but the focus was returning to the next line of the script without waiting for the setup.exe to finish. I tried the above solutions with no luck.

In the end, piping the command through more did the trick.

setup.exe {arguments} | more

In JDK7, "more NIO features" should have methods to apply the visitor pattern over a file tree or just the immediate contents of a directory - no need to find all the files in a potentially huge directory before iterating over them.

This does money along with the commas

def format_money(money, presym='$', postsym=''):
    fmt = '%0.2f' % money
    dot = string.find(fmt, '.')
    ret = []
    if money < 0 :
        ret.append('(')
        p0 = 1
    else :
        p0 = 0
    ret.append(presym)
    p1 = (dot-p0) % 3 + p0
    while True :
        ret.append(fmt[p0:p1])
        if p1 == dot : break
        ret.append(',')
        p0 = p1
        p1 += 3
    ret.append(fmt[dot:])   # decimals
    ret.append(postsym)
    if money < 0 : ret.append(')')
    return ''.join(ret)

sys.tables

Contains all tables. so exec this query to get all tables with details.

SELECT * FROM sys.tables

or simply select Name from sys.tables to get the name of all tables.

SELECT Name From sys.tables

This is C++11 code. In C++11, the && token can be used to mean an "rvalue reference".

You can resolve the error by providing the column names you are affecting.

> INSERT INTO table_name (column1,column2,column3)
 `VALUES(50,'Jon Snow','Eye');`

please note that the semi colon should be added only after the statement providing values

• std::ostringstream

#include <sstream>

std::ostringstream s;
s << "John " << age;
std::string query(s.str());

• std::to_string (C++11)

std::string query("John " + std::to_string(age));

• boost::lexical_cast

#include <boost/lexical_cast.hpp>

std::string query("John " + boost::lexical_cast<std::string>(age));

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

This lesson from the Java tutorial explains each Swing component in detail, with examples and API links.

Actually is quite easy with this option at the end:

c:\start BATCH.bat -WindowStyle Hidden

from item in db.vw_Dropship_OrderItems
    where (listStatus != null ? listStatus.Contains(item.StatusCode) : true) &&
    (listMerchants != null ? listMerchants.Contains(item.MerchantId) : true)
    select item;

Might give strange behavior if both listMerchants and listStatus are both null.

You are looking for the float.h header.

mylist = [0.30000000000000004, 0.5, 0.20000000000000001]
myRoundedList =  [round(x,2) for x in mylist] 
# [0.3, 0.5, 0.2]

Make sure that the component has the "exported" flag set to true. Also the component defining the permission should be installed before the component that uses it.

Yes, 1 byte does encode a character (inc spaces etc) from the ASCII set. However in data units assigned to character encoding it can and often requires in practice up to 4 bytes. This is because English is not the only character set. And even in English documents other languages and characters are often represented. The numbers of these are very many and there are very many other encoding sets, which you may have heard of e.g. BIG-5, UTF-8, UTF-32. Most computers now allow for these uses and ensure the least amount of garbled text (which usually means a missing encoding set.) 4 bytes is enough to cover these possible encodings. I byte per character does not allow for this and in use it is larger often 4 bytes per possible character for all encodings, not just ASCII. The final character may only need a byte to function or be represented on screen, but requires 4 bytes to be located in the rather vast global encoding "works".

Building on Olie and Algal's answer, here is an updated answer for Swift 3

public func getRGBAs(fromImage image: UIImage, x: Int, y: Int, count: Int) -> [UIColor] {

var result = [UIColor]()

// First get the image into your data buffer
guard let cgImage = image.cgImage else {
    print("CGContext creation failed")
    return []
}

let width = cgImage.width
let height = cgImage.height
let colorSpace = CGColorSpaceCreateDeviceRGB()
let rawdata = calloc(height*width*4, MemoryLayout<CUnsignedChar>.size)
let bytesPerPixel = 4
let bytesPerRow = bytesPerPixel * width
let bitsPerComponent = 8
let bitmapInfo: UInt32 = CGImageAlphaInfo.premultipliedLast.rawValue | CGBitmapInfo.byteOrder32Big.rawValue

guard let context = CGContext(data: rawdata, width: width, height: height, bitsPerComponent: bitsPerComponent, bytesPerRow: bytesPerRow, space: colorSpace, bitmapInfo: bitmapInfo) else {
    print("CGContext creation failed")
    return result
}

context.draw(cgImage, in: CGRect(x: 0, y: 0, width: width, height: height))

// Now your rawData contains the image data in the RGBA8888 pixel format.
var byteIndex = bytesPerRow * y + bytesPerPixel * x

for _ in 0..<count {
    let alpha = CGFloat(rawdata!.load(fromByteOffset: byteIndex + 3, as: UInt8.self)) / 255.0
    let red = CGFloat(rawdata!.load(fromByteOffset: byteIndex, as: UInt8.self)) / alpha
    let green = CGFloat(rawdata!.load(fromByteOffset: byteIndex + 1, as: UInt8.self)) / alpha
    let blue = CGFloat(rawdata!.load(fromByteOffset: byteIndex + 2, as: UInt8.self)) / alpha
    byteIndex += bytesPerPixel

    let aColor = UIColor(red: red, green: green, blue: blue, alpha: alpha)
    result.append(aColor)
}

free(rawdata)

return result
}

Click the "Validation" button, and uncheck the checkbox for checking validity

Be advised though that this is pretty unsecure as it leaves you wide open to accept any invalid certificate. I'd only do this if using the browser on an Intranet where the validity of the cert isn't a concern to you, or you aren't concerned in general.

I had the same problem. I was very new to iPhone development and it was my first time trying to submit my app to App-store...

Check the following :

1. Check that your current "Bundle Identifier" is same as your current "Provisioning Profile" name in "Code Signing Identity".

2. In "Code Signing identity block" - Check Debug AND Distribution have the same "Code Signing Information". Try to keep the "Code Signing Information" same in all the Blocks.

3. Try to Download the "Provisioning Profile" again and double click on the profile. Then use that newly downloaded profile in your "Code Signing Identity".

4. Try to Download the "Certificate" again from the "developer.apple.com" and double click on the certificate. (It worked in my case)

Then "Clean" the project and click on "Build for Archive". Hope your code will be archived perfectly.

Well, it's fairly simple to do.

On the window resize event handler, calculate how much the window has grown/shrunk, and use that fraction to adjust 1) Height, 2) Width, 3) Canvas.Top, 4) Canvas.Left properties of all the child controls inside the canvas.

Here's the code:

private void window1_SizeChanged(object sender, SizeChangedEventArgs e)
        {
            myCanvas.Width = e.NewSize.Width;
            myCanvas.Height = e.NewSize.Height;

            double xChange = 1, yChange = 1;

            if (e.PreviousSize.Width != 0)
            xChange = (e.NewSize.Width/e.PreviousSize.Width);

            if (e.PreviousSize.Height != 0)
            yChange = (e.NewSize.Height / e.PreviousSize.Height);

            foreach (FrameworkElement fe in myCanvas.Children )
            {   
                /*because I didn't want to resize the grid I'm having inside the canvas in this particular instance. (doing that from xaml) */            
                if (fe is Grid == false)
                {
                    fe.Height = fe.ActualHeight * yChange;
                    fe.Width = fe.ActualWidth * xChange;

                    Canvas.SetTop(fe, Canvas.GetTop(fe) * yChange);
                    Canvas.SetLeft(fe, Canvas.GetLeft(fe) * xChange);

                }
            }
        }

This could also caused by mismatching brace/parenthesis.

$(TARGET}:
    do_something

Just use parenthesises and you'll be fine.

Actually, I see that ECMAScript (JavaScript) DOES INDEED have a goto statement. However, the JavaScript goto has two flavors!

The two JavaScript flavors of goto are called labeled continue and labeled break. There is no keyword "goto" in JavaScript. The goto is accomplished in JavaScript using the break and continue keywords.

And this is more or less explicitly stated on the w3schools website here http://www.w3schools.com/js/js_switch.asp.

I find the documentation of the labeled continue and labeled break somewhat awkwardly expressed.

The difference between the labeled continue and labeled break is where they may be used. The labeled continue can only be used inside a while loop. See w3schools for some more information.

===========

Another approach that will work is to have a giant while statement with a giant switch statement inside:

while (true)
{
    switch (goto_variable)
    {
        case 1:
            // some code
            goto_variable = 2
            break;
        case 2:
            goto_variable = 5   // case in etc. below
            break;
        case 3:
            goto_variable = 1
            break;

         etc. ...
    }

}

This site uses the method isEmpty().

Edit: content grabbed from site, before the url will going to be invalid.

Worksheets("Sheet1").Range("A1").Sort _
    key1:=Worksheets("Sheet1").Range("A1")
Set currentCell = Worksheets("Sheet1").Range("A1")
Do While Not IsEmpty(currentCell)
    Set nextCell = currentCell.Offset(1, 0)
    If nextCell.Value = currentCell.Value Then
        currentCell.EntireRow.Delete
    End If
    Set currentCell = nextCell
Loop

In the first step the data in the first column from Sheet1 will be sort. In the second step, all rows with same data will be removed.

The best way to solve this problem "X-CSRF-TOKEN" is to add the following code to your main layout, and continue making your ajax calls normally:

In header

<meta name="csrf-token" content="{{ csrf_token() }}" />

In script

<script type="text/javascript">
$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});
</script>

        }
    }

    public static T DeserializeObject<T>(string xml)
         where T : new()
    {
        if (string.IsNullOrEmpty(xml))
        {
            return new T();
        }
        try
        {
            using (var stringReader = new StringReader(xml))
            {
                var serializer = new XmlSerializer(typeof(T));
                return (T)serializer.Deserialize(stringReader);
            }
        }
        catch (Exception ex)
        {
            return new T();
        }
    }
}

You can call it using:

MyCustomObject myObject = new MyCustomObject();
string xmlString = XmlConvert.SerializeObject(myObject)
myObject = XmlConvert.DeserializeObject<MyCustomObject>(xmlString);

Or you can do like this:

your_df.to_excel( r'C:\Users\full_path\excel_name.xlsx',
                  sheet_name= 'your_sheet_name'
                )

Also note that the SPOOL output is driven by a few SQLPlus settings:

• SET LINESIZE nn - maximum line width; if the output is longer it will wrap to display the contents of each result row.

• SET TRIMSPOOL OFF|ON - if set OFF (the default), every output line will be padded to LINESIZE. If set ON, every output line will be trimmed.

• SET PAGESIZE nn - number of lines to output for each repetition of the header. If set to zero, no header is output; just the detail.

Those are the biggies, but there are some others to consider if you just want the output without all the SQLPlus chatter.

In your example you actually have 2 variables with the same name. The (global) variable x and the function scoped variable x. Interesting to see that javascript, when given a choice of what to do with 2 variables of the same name, goes with the function scoped name and ignores the out-of-scope variable.

It's probably not safe to presume javascript will always behave this way...

Cheers!

TRUNCATE will blank your table and reset primary key DELETE will also make your table blank but it will not reset primary key.

we can use for truncate

TRUNCATE TABLE tablename

we can use for delete

DELETE FROM tablename

we can also give conditions as below

DELETE FROM tablename WHERE id='xyz'

To answer to your second question. You can just hit the IP address of the machine that your flask app is running, e.g. 192.168.1.100 in a browser on different machine on the same network and you are there. Though, you will not be able to access it if you are on a different network. Firewalls or VLans can cause you problems with reaching your application. If that computer has a public IP, then you can hit that IP from anywhere on the planet and you will be able to reach the app. Usually this might impose some configuration, since most of the public servers are behind some sort of router or firewall.

AFAIK the delay method only works for numeric CSS modifications.

For other purposes JavaScript comes with a setTimeout method:

window.setTimeout(function(){$("#div").removeClass("error");}, 1000);

From the PHP Manual:

Warning This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide. Alternatives to this function include:

mysqli_connect()

PDO::__construct()

use MySQLi or PDO

<?php
$con = mysqli_connect('localhost', 'username', 'password', 'database');

One of the most significant JIT optimizations is method inlining. Java can even inline virtual methods if it can guarantee runtime correctness. This kind of optimization usually cannot be performed by standard static compilers because it needs whole-program analysis, which is hard because of separate compilation (in contrast, JIT has all the program available to it). Method inlining improves other optimizations, giving larger code blocks to optimize.

Standard memory allocation in Java/C# is also faster, and deallocation (GC) is not much slower, but only less deterministic.

So many answers trying to calculate the height of the document. But it wasn't calculating correctly for me. However, both of these worked:

jquery

    $('html,body').animate({scrollTop: 9999});

or just js

    window.scrollTo(0,9999);

jQuery Validation Plugin already implements min and max rules, we just need to create an adapter for our custom attribute:

public class MaxAttribute : ValidationAttribute, IClientValidatable
{
    private readonly int maxValue;

    public MaxAttribute(int maxValue)
    {
        this.maxValue = maxValue;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var rule = new ModelClientValidationRule();

        rule.ErrorMessage = ErrorMessageString, maxValue;

        rule.ValidationType = "max";
        rule.ValidationParameters.Add("max", maxValue);
        yield return rule;
    }

    public override bool IsValid(object value)
    {
        return (int)value <= maxValue;
    }
}

Adapter:

$.validator.unobtrusive.adapters.add(
   'max',
   ['max'],
   function (options) {
       options.rules['max'] = parseInt(options.params['max'], 10);
       options.messages['max'] = options.message;
   });

Min attribute would be very similar.

Another trick not yet mentioned is to have the class which implements a property (e.g. Foo of type Bar) also define a delegate delegate void ActByRef<T1,T2>(ref T1 p1, ref T2 p2); and implement a method ActOnFoo<TX1>(ref Bar it, ActByRef<Bar,TX1> proc, ref TX1 extraParam1) (and possibly versions for two and three "extra parameters" as well) which will pass its internal representation of Foo to the supplied procedure as a ref parameter. This has a couple of big advantages over other methods of working with the property:

1. The property is updated "in place"; if the property is of a type that's compatible with `Interlocked` methods, or if it is a struct with exposed fields of such types, the `Interlocked` methods may be used to perform atomic updates to the property.
2. If the property is an exposed-field structure, the fields of the structure may be modified without having to make any redundant copies of it.
3. If the `ActByRef` method passes one or more `ref` parameters through from its caller to the supplied delegate, it may be possible to use a singleton or static delegate, thus avoiding the need to create closures or delegates at run-time.
4. The property knows when it is being "worked with". While it is always necessary to use caution executing external code while holding a lock, if one can trust callers not to do too do anything in their callback that might require another lock, it may be practical to have the method guard the property access with a lock, such that updates which aren't compatible with `CompareExchange` could still be performed quasi-atomically.

Passing things be ref is an excellent pattern; too bad it's not used more.

To inactivate the non-desktop styles you just have to change 4 lines of code in the variables.less file. Set the screen width breakpoints in the variables.less file like this:

// Media queries breakpoints
// --------------------------------------------------

// Extra small screen / phone
// Note: Deprecated @screen-xs and @screen-phone as of v3.0.1
@screen-xs:                  1px;
@screen-xs-min:              @screen-xs;
@screen-phone:               @screen-xs-min;

// Small screen / tablet
// Note: Deprecated @screen-sm and @screen-tablet as of v3.0.1
@screen-sm:                  2px;
@screen-sm-min:              @screen-sm;
@screen-tablet:              @screen-sm-min;

// Medium screen / desktop
// Note: Deprecated @screen-md and @screen-desktop as of v3.0.1
@screen-md:                  3px;
@screen-md-min:              @screen-md;
@screen-desktop:             @screen-md-min;

// Large screen / wide desktop
// Note: Deprecated @screen-lg and @screen-lg-desktop as of v3.0.1
@screen-lg:                  9999px;
@screen-lg-min:              @screen-lg;
@screen-lg-desktop:          @screen-lg-min;

This sets the min-width on the desktop style media query lower so that it applies to all screen widths. Thanks to 2calledchaos for the improvement! Some base styles are defined in the mobile styles, so we need to be sure to include them.

Edit: chris notes that you can set these variables in the online less compiler on the bootstrap site

I render context path to attribute of link tag with id="contextPahtHolder" and then obtain it in JS code. For example:

<html>
    <head>
        <link id="contextPathHolder" data-contextPath="${pageContext.request.contextPath}"/>
    <body>
        <script src="main.js" type="text/javascript"></script>
    </body>
</html>

main.js

var CONTEXT_PATH = $('#contextPathHolder').attr('data-contextPath');
$.get(CONTEXT_PATH + '/action_url', function() {});

If context path is empty (like in embedded servlet container istance), it will be empty string. Otherwise it contains contextPath string

If you can't find the build path error, sometimes menu Project ? Clean... works like a charm.

In your case I use: val dm = ListBuffer[String]() and val dk = ListBuffer[Map[String,anyRef]]()

In case you want to handle intent on opened activity, you can use PendintIntent (Complete steps below):

public class SMSReciver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        final Bundle bundle = intent.getExtras();
        try {
            if (bundle != null) {
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++) {
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                    try {
                        if (senderNum.contains("MOB_NUMBER")) {
                            Toast.makeText(context,"",Toast.LENGTH_SHORT).show();

                            Intent intentCall = new Intent(context, MainActivity.class);
                            intentCall.putExtra("message", currentMessage.getMessageBody());

                            PendingIntent pendingIntent= PendingIntent.getActivity(context, 0, intentCall, PendingIntent.FLAG_UPDATE_CURRENT);
                            pendingIntent.send();
                        }
                    } catch (Exception e) {
                    }
                }
            }
        } catch (Exception e) {
        }
    }
} 

manifest:

<activity android:name=".MainActivity"
            android:launchMode="singleTask"/>
<receiver android:name=".SMSReciver">
            <intent-filter android:priority="1000">
                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
            </intent-filter>
        </receiver>

onNewIntent:

 @Override
         protected void onNewIntent(Intent intent) {
                super.onNewIntent(intent);
                Toast.makeText(this, "onNewIntent", Toast.LENGTH_SHORT).show();

                onSMSReceived(intent.getStringExtra("message"));

            }

permissions:

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />

I ran into the same issue and solved it by downloading api level 20 using sdk manager and changing every string that points to android-L. I did it because I dont have a kitkat device and don't want to use emulator. See the image download the marked one.

Here's my build config:

apply plugin: 'com.android.application'

android {
compileSdkVersion 20//changed this from default
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "com.example.subash.test"
    minSdkVersion 12//changed this from default
    targetSdkVersion 20//changed this from default
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

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

ClickOnce apps are designed so that the end user downloads a "downloader" - the ClickOnce app, then when ya run it, it downloads and installs in %LocalAppData%\Apps\2.0..... and then it's random folder names for every OS install you do. Backing up is pointless and so is trying to move the program. The point of ClickOnce is 2-Fold: 1. AutoUpdating of the program 2. The end user has no installer and also can't move the app or it breaks

The %LocalAppData%\Apps\2.0..... folder is the program AND %LocalAppData%\GitHub is the settings folder.

I'm not going to cover how to circumvent this - only stating the above. :P

The best 'tip' I can say legitimately is: You 'can' in some cases move the final folder that all the files are in and use a symlink back, if you are low on space. But, not all apps will work and essentially will delete the symlink once you they run. Then they might reinstall or simply just remove the link. Keep in mind also, other apps may be using that same final folder as well, so move the folder will affect those too.

<select name="owner">
<?php 
$sql = mysql_query("SELECT username FROM users");
while ($row = mysql_fetch_array($sql)){
echo "<option value=\"owner1\">" . $row['username'] . "</option>";
}
?>
</select>

var dict = {};

dict['key'] = "testing";

console.log(dict);

works just like python :)

console output:

Object {key: "testing"} 

One simple method is to use place to use an image as a background image. This is the type of thing that place is really good at doing.

For example:

background_image=tk.PhotoImage(...)
background_label = tk.Label(parent, image=background_image)
background_label.place(x=0, y=0, relwidth=1, relheight=1)

You can then grid or pack other widgets in the parent as normal. Just make sure you create the background label first so it has a lower stacking order.

Note: if you are doing this inside a function, make sure you keep a reference to the image, otherwise the image will be destroyed by the garbage collector when the function returns. A common technique is to add a reference as an attribute of the label object:

background_label.image = background_image

Yep. Cloudflare uses it for its DNS instructions homepage: https://1.1.1.1

Here you will find a better solution OLTP vs. OLAP

• OLTP (On-line Transaction Processing) is involved in the operation of a particular system. OLTP is characterized by a large number of short on-line transactions (INSERT, UPDATE, DELETE). The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second. In OLTP database there is detailed and current data, and schema used to store transactional databases is the entity model (usually 3NF). It involves Queries accessing individual record like Update your Email in Company database.

• OLAP (On-line Analytical Processing) deals with Historical Data or Archival Data. OLAP is characterized by relatively low volume of transactions. Queries are often very complex and involve aggregations. For OLAP systems a response time is an effectiveness measure. OLAP applications are widely used by Data Mining techniques. In OLAP database there is aggregated, historical data, stored in multi-dimensional schemas (usually star schema). Sometime query need to access large amount of data in Management records like what was the profit of your company in last year.

You should create a ModelForm (docs), which has a field that uses the PasswordInput widget from the forms library.

It would look like this:

models.py

from django import models
class User(models.Model):
    username = models.CharField(max_length=100)
    password = models.CharField(max_length=50)

forms.py (not views.py)

from django import forms
class UserForm(forms.ModelForm):
    class Meta:
        model = User
        widgets = {
        'password': forms.PasswordInput(),
    }

For more about using forms in a view, see this section of the docs.

For Mac , what worked for me is creating a .my.cnf file in my ~ path. Hope this helps.

datePicker's onSelect equivalent is the dateSelected event.

$(function() {
    $('.date-pick').datePicker( {
        selectWeek: true,
        inline: true,
        startDate: '01/01/2000',
        firstDay: 1,
    }).bind('dateSelected', function(e, selectedDate, $td) {
        alert(selectedDate);
    });
});

This page has a good example showing the dateSelected event and other events being bound.

There's an Abstract Class Dictionary

http://docs.oracle.com/javase/6/docs/api/java/util/Dictionary.html

However this requires implementation.

Java gives us a nice implementation called a Hashtable

http://docs.oracle.com/javase/6/docs/api/java/util/Hashtable.html

With the module pygame.draw shapes like rectangles, circles, polygons, liens, ellipses or arcs can be drawn. Some examples:

pygame.draw.rect draws filled rectangular shapes or outlines. The arguments are the target Surface (i.s. the display), the color, the rectangle and the optional outline width. The rectangle argument is a tuple with the 4 components (x, y, width, height), where (x, y) is the upper left point of the rectangle. Alternatively, the argument can be a pygame.Rect object:

pygame.draw.rect(window, color, (x, y, width, height))

rectangle = pygame.Rect(x, y, width, height)
pygame.draw.rect(window, color, rectangle)

pygame.draw.circle draws filled circles or outlines. The arguments are the target Surface (i.s. the display), the color, the center, the radius and the optional outline width. The center argument is a tuple with the 2 components (x, y):

pygame.draw.circle(window, color, (x, y), radius)

pygame.draw.polygon draws filled polygons or contours. The arguments are the target Surface (i.s. the display), the color, a list of points and the optional contour width. Each point is a tuple with the 2 components (x, y):

pygame.draw.polygon(window, color, [(x1, y1), (x2, y2), (x3, y3)])

Minimal example:

import pygame

pygame.init()

window = pygame.display.set_mode((200, 200))
clock = pygame.time.Clock()

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.fill((255, 255, 255))

    pygame.draw.rect(window, (0, 0, 255), (20, 20, 160, 160))
    pygame.draw.circle(window, (255, 0, 0), (100, 100), 80)
    pygame.draw.polygon(window, (255, 255, 0), 
        [(100, 20), (100 + 0.8660 * 80, 140), (100 - 0.8660 * 80, 140)])

    pygame.display.flip()

pygame.quit()
exit()

just remove:

...
//dataType: "json",
url: "index.php",
data: {myData:postData},
//contentType: "application/json; charset=utf-8",
...

Im not sure this will solve your problem since I dont know where it originats from, but when I import a project i go File -> Import -> Existing projects into workspace. Maybe it will circumvent your problem.

Support for the extended ternary operator was added in Twig 1.12.0.

1. If foo echo yes else echo no:

   {{ foo ? 'yes' : 'no' }}
   

2. If foo echo it, else echo no:

   {{ foo ?: 'no' }}
   

   or

   {{ foo ? foo : 'no' }}
   

3. If foo echo yes else echo nothing:

   {{ foo ? 'yes' }}
   

   or

   {{ foo ? 'yes' : '' }}
   

4. Returns the value of foo if it is defined and not null, no otherwise:

   {{ foo ?? 'no' }}
   

5. Returns the value of foo if it is defined (empty values also count), no otherwise:

   {{ foo|default('no') }}
   

If you didn't commit the transaction yet, try rollback. If you have already committed the transaction (by commit or by exiting the command line client), you must restore the data from your last backup.

The only thing that worked for me:

g.drawOval((getWidth()-200)/2,(getHeight()-200)/2, 200, 200);    

Instead of using -c, just pipe it to wc -l.

grep string * | wc -l

This will list each occurrence on a single line and then count the number of lines.

This will miss instances where the string occurs 2+ times on one line, though.

In my case all icons suddenly disappeared .

Solution :

1. Go To Task Manager and kill Explorer
2. In Task Manager File (New Task (Run) ) => explorer

and all appeared again...

In (at least) Ubuntu when using bash, it tells you what package you need to install if you type in a command and its not found in your path. My terminal says you need to install 'texinfo' package.

You can use the following css to resize the image for mobile view

Use the below class to Generate a Salt first. Each user needs to have a different salt, we can save it in the database along with the other user properties. The rounds value decides the number of times the password will be hashed.

For more details: https://docs.microsoft.com/en-us/dotnet/api/system.security.cryptography.rfc2898derivebytes.-ctor?view=netcore-3.1#System_Security_Cryptography_Rfc2898DeriveBytes__ctor_System_Byte___System_Byte___System_Int32_

public class HashSaltWithRounds
{
    int saltLength = 32;
    public byte[] GenerateSalt()
    {
        using (var randomNumberGenerator = new RNGCryptoServiceProvider())
        {
            var randomNumber = new byte[saltLength];
            randomNumberGenerator.GetBytes(randomNumber);
            return randomNumber;
        }
    }

    public string HashDataWithRounds(byte[] password, byte[] salt, int rounds)
    {
        using(var rfc2898= new Rfc2898DeriveBytes(password, salt, rounds))
        {
            return Convert.ToBase64String(rfc2898.GetBytes(32));
        }
    }
}

We can call it from a console application as follows. I have hashed the password twice using the same salt.

public class Program
{
    public static void Main(string[] args)
    {
        int numberOfIterations = 99;
        var hashFunction = new HashSaltWithRounds();

        string password = "Your Password Here";
        byte[] salt = hashFunction.GenerateSalt();

        var hashedPassword1 = hashFunction.HashDataWithRounds(Encoding.UTF8.GetBytes(password), salt, numberOfIterations);
        var hashedPassword2 = hashFunction.HashDataWithRounds(Encoding.UTF8.GetBytes(password), salt, numberOfIterations);

        Console.WriteLine($"hashedPassword1 :{hashedPassword1}");
        Console.WriteLine($"hashedPassword2 :{hashedPassword2}");
        Console.WriteLine(hashedPassword1.Equals(hashedPassword2));

        Console.ReadLine();

    }
}

You can use the selectedIndex property to set it to the first option:

document.getElementById("select").selectedIndex = 0;

$post_data = [
  "item" => [
    'item_type_id' => $item_type,
    'string_key' => $string_key,
    'string_value' => $string_value,
    'string_extra' => $string_extra,
    'is_public' => $public,
    'is_public_for_contacts' => $public_contacts
  ]
];

$post_data = json_encode(post_data);
$post_data = json_decode(post_data);
return $post_data;

Use CSS position: absolute; followed by top: 0px; left 0px; in the style attribute of each DIV. Replace the pixel values with whatever you want.

You can use z-index: x; to set the vertical "order" (which one is "on top"). Replace x with a number, higher numbers are on top of lower numbers.

Here is how your new code would look:

<div>
  <div id="backdrop" style="z-index: 1; position: absolute; top: 0px; left: 0px;"><img alt="" src='/backdrop.png' /></div>
  <div id="curtain" style="z-index: 2; position: absolute; top: 0px; left: 0px; background-image:url(/curtain.png);background-position:100px 200px; height:250px; width:500px;">&nbsp;</div>
</div>

Here I got the error: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

Because you didn't pass a base64-encoded string. Look at your functions: both download and dataURItoBlob do expect a data URI for some reason; you however are passing a plain html markup string to download in your example.

Not only is HTML invalid as base64, you are calling .split(',')[1] on it which will yield undefined - and "undefined" is not a valid base64-encoded string either.

I don't know, but I read that I need to encode my string to base64

That doesn't make much sense to me. You want to encode it somehow, only to decode it then?

What should I call and how?

Change the interface of your download function back to where it received the filename and text arguments.

Notice that the BlobBuilder does not only support appending whole strings (so you don't need to create those ArrayBuffer things), but also is deprecated in favor of the Blob constructor.

Can I put a name on my saved file?

Yes. Don't use the Blob constructor, but the File constructor.

function download(filename, text) {
    try {
        var file = new File([text], filename, {type:"text/plain"});
    } catch(e) {
        // when File constructor is not supported
        file = new Blob([text], {type:"text/plain"});
    }
    var url  = window.URL.createObjectURL(file);
    …
}

download('test.html', "<html>" + document.documentElement.innerHTML + "</html>");

See JavaScript blob filename without link on what to do with that object url, just setting the current location to it doesn't work.

HTML Code:-

<input type="text" name="txt1" id="txt1" onkeypress="return AddKeyPress(event);" />      

<input type="button" id="btnclick">

Java Script Code

function AddKeyPress(e) { 
        // look for window.event in case event isn't passed in
        e = e || window.event;
        if (e.keyCode == 13) {
            document.getElementById('btnEmail').click();
            return false;
        }
        return true;
    }

My solution is to use ggplot2. It takes care of these types of things automatically. The biggest thing is to arrange the data appropriately.

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)
df <- data.frame(x=rep(x,2), y=c(y1, y2), class=c(rep("y1", 5), rep("y2", 5)))

Then use ggplot2 to plot it

library(ggplot2)
ggplot(df, aes(x=x, y=y, color=class)) + geom_point()

This is saying plot the data in df, and separate the points by class.

The plot generated is

I had Java 7 and 8 installed and I want to redirect to java 7 but the java version in my cmd prompt window shows Java 8.
Added Java 7 bin directory path (C:\Program Files\Java\jdk1.7.0_10\bin) to PATH variable at the end, but did not work out and shows Java 8. So I changed the Java 7 path to the starting of the path value and it worked.
Opened a new cmd prompt window and checked my java version and now it shows Java 7

Inheritance is very powerful, but you can't force it (see: the circle-ellipse problem). If you really can't be completely sure of a true "is-a" subtype relationship, then it's best to go with composition.

This ought to do it:

SELECT *
FROM YourTable
WHERE ARIDNR IN (
    SELECT ARIDNR
    FROM YourTable
    GROUP BY ARIDNR
    HAVING COUNT(*) > 1
)

The idea is to use the inner query to identify the records which have a ARIDNR value that occurs 1+ times in the data, then get all columns from the same table based on that set of values.

For me I had to make sure the the program I was coping file to was not running at the time. There weren't any errors in the syntax. Hope this helps someone.

Timothy Budd has a fine implementation of a Rational class in his "Data Structures in C++". Different language, of course, but it ports over to Java very nicely.

I'd recommend more constructors. A default constructor would have numerator 0, denominator 1. A single arg constructor would assume a denominator of 1. Think how your users might use this class.

No check for zero denominator? Programming by contract would have you add it.

At the time of my writing this answer, the accepted answer to this question appears to state that browsers are not required to delete a cookie when receiving a replacement cookie whose Expires value is in the past. That claim is false. Setting Expires to be in the past is the standard, spec-compliant way of deleting a cookie, and user agents are required by spec to respect it.

Using an Expires attribute in the past to delete a cookie is correct and is the way to remove cookies dictated by the spec. The examples section of RFC 6255 states:

Finally, to remove a cookie, the server returns a Set-Cookie header with an expiration date in the past. The server will be successful in removing the cookie only if the Path and the Domain attribute in the Set-Cookie header match the values used when the cookie was created.

The User Agent Requirements section includes the following requirements, which together have the effect that a cookie must be immediately expunged if the user agent receives a new cookie with the same name whose expiry date is in the past

11. If [when receiving a new cookie] the cookie store contains a cookie with the same name, domain, and path as the newly created cookie:

    1. ...
    2. ...
    3. Update the creation-time of the newly created cookie to match the creation-time of the old-cookie.
    4. Remove the old-cookie from the cookie store.

12. Insert the newly created cookie into the cookie store.

A cookie is "expired" if the cookie has an expiry date in the past.

The user agent MUST evict all expired cookies from the cookie store if, at any time, an expired cookie exists in the cookie store.

Points 11-3, 11-4, and 12 above together mean that when a new cookie is received with the same name, domain, and path, the old cookie must be expunged and replaced with the new cookie. Finally, the point below about expired cookies further dictates that after that is done, the new cookie must also be immediately evicted. The spec offers no wiggle room to browsers on this point; if a browser were to offer the user the option to disable cookie expiration, as the accepted answer suggests some browsers do, then it would be in violation of the spec. (Such a feature would also have little use, and as far as I know it does not exist in any browser.)

Why, then, did the OP of this question observe this approach failing? Though I have not dusted off a copy of Internet Explorer to check its behaviour, I suspect it was because the OP's Expires value was malformed! They used this value:

expires=Thu, Jan 01 1970 00:00:00 UTC;

However, this is syntactically invalid in two ways.

The syntax section of the spec dictates that the value of the Expires attribute must be a

rfc1123-date, defined in [RFC2616], Section 3.3.1

Following the second link above, we find this given as an example of the format:

Sun, 06 Nov 1994 08:49:37 GMT

and find that the syntax definition...

1. requires that dates be written in day month year format, not month day year format as used by the question asker.

   Specifically, it defines rfc1123-date as follows:

   rfc1123-date = wkday "," SP date1 SP time SP "GMT"
   

   and defines date1 like this:

   date1        = 2DIGIT SP month SP 4DIGIT
                ; day month year (e.g., 02 Jun 1982)
   

and

2. doesn't permit UTC as a timezone.

   The spec contains the following statement about what timezone offsets are acceptable in this format:

   All HTTP date/time stamps MUST be represented in Greenwich Mean Time (GMT), without exception.

   What's more if we dig deeper into the original spec of this datetime format, we find that in its initial spec in https://tools.ietf.org/html/rfc822, the Syntax section lists "UT" (meaning "universal time") as a possible value, but does not list not UTC (Coordinated Universal Time) as valid. As far as I know, using "UTC" in this date format has never been valid; it wasn't a valid value when the format was first specified in 1982, and the HTTP spec has adopted a strictly more restrictive version of the format by banning the use of all "zone" values other than "GMT".

If the question asker here had instead used an Expires attribute like this, then:

expires=Thu, 01 Jan 1970 00:00:00 GMT;

then it would presumably have worked.

The two alternative you gave are semantically identical, but using make([]int, 0) will result in an internal call to runtime.makeslice (Go 1.14).

You also have the option to leave it with a nil value:

var myslice []int

As written in the Golang.org blog:

a nil slice is functionally equivalent to a zero-length slice, even though it points to nothing. It has length zero and can be appended to, with allocation.

A nil slice will however json.Marshal() into "null" whereas an empty slice will marshal into "[]", as pointed out by @farwayer.

None of the above options will cause any allocation, as pointed out by @ArmanOrdookhani.

hmemcpy answer was totally for me and thanks to other friends who answered.

I grab the HttpValueCollection using Reflector and wrote the following code

        var hebe = new HttpValueCollection();
        hebe.Add(HttpUtility.ParseQueryString(Request.Url.Query));

        if (!string.IsNullOrEmpty(hebe["Language"]))
            hebe.Remove("Language");

        Response.Redirect(Request.Url.AbsolutePath + "?" + hebe );

I had a similar problem. I had installed JDK7 update 1 but couldn't use it (probably because I found a JRE6 that I deleted after installing JDK7). Uninstalling JDK7 was impossible. The solution was to add the JRE registry entries by hand.

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
"CurrentVersion"="1.7"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7.0_01]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

You'll have to adjust the above to your own directories and version.

If this doesn't help, there's still JavaRa http://raproducts.org/wordpress/ .

Like some here, I ended up writing a wrapper around the JSch library.

It's called way-secshell and it is hosted on GitHub:

https://github.com/objectos/way-secshell

// scp myfile.txt localhost:/tmp
File file = new File("myfile.txt");
Scp res = WaySSH.scp()
  .file(file)
  .toHost("localhost")
  .at("/tmp")
  .send();

For security reasons, you can only get the url for as long as the contents of the iframe, and the referencing javascript, are served from the same domain. As long as that is true, something like this will work:

document.getElementById("iframe_id").contentWindow.location.href

If the two domains are mismatched, you'll run into cross site reference scripting security restrictions.

Actually, the HTML 4.01 spec says that these attributes do not require values. I haven't personally encountered a situation where providing a value rendered these controls as unselected.

Here are the respective links to the spec document for selected and checked.

Edit: Firebug renders the checkbox as checked regardless of any values I put in quotes for the checked attribute (including just typing "checked" with no values whatsoever), and IE 8's Developer Tools forces checked="checked". I'm not sure if any similar tools exist for other browsers that might alter the rendered state of a checkbox, however.

I've set the time to 1000*36000.

function display() { 
  var now = new Date();
  var time = now.getTime();
  var expireTime = time + 1000*36000;
  now.setTime(expireTime);
  document.cookie = 'cookie=ok;expires='+now.toUTCString()+';path=/';
  //console.log(document.cookie);  // 'Wed, 31 Oct 2012 08:50:17 UTC'
}

The question is tagged with ubuntu, but the solution of un-commenting the extension=mysqli.dll is specific to windows. I am confused here?!, anyways, first thing run <? php phpinfo ?> and search for mysql* under Configuration heading. If you don't see such a thing implies you have not installed or enabled php-mysql. So first install php-mysql

sudo apt get install php-mysql

This command will install php-mysql depending on the php you have already installed, so no worries about the version!!.

Then comes the unix specific solution, in the php.ini file un-comment the line

extension=msql.so

verify that msql.so is present in /usr/lib/php/<timestamp_folder>, ELSE

extension=path/to/msql.so

Then finally restart the apache and mysql services, and you should now see the mysql section under Configrations heading in phpinfo page

I just set chrome as my default browser and jupyter launches in Chrome now.

However, we have also the following approach, but it did not work for me:

"CONDA version 4.7.5 and jupyter 6.0.0. - Windows 10"

1) Open Anaconda and launch your environment in terminal

2) Create config file and open file in notepad

3) Modify line of NotebookApp with chrome and save modification

4) Launch Jupyter

:( ... but it still launches in Mozilla.

this works for me :

import groovy.json.JsonBuilder
properties = new Properties()
properties.put("name", "zhangsan")

println new JsonBuilder(properties).toPrettyString()

I think the most important thing to realize when troubleshooting this bug is that it manifests when you attempt to instantiate a component that doesn't exist. This component doesn't have to be imported. In my case I was passing components as properties. I forgot to update one of the calls to properly pass the component after some refactoring. Unfortunately, since JS isn't statically typed my bug wasn't caught, and it took some time to figure out what was happening.

To troubleshoot this bug inspect the component before you render it, to make sure that it's the type of component you expect.

I put together a little C program to print out the current timestamp (locale-safe, no bad characters...). Then, I use the FOR command to save the result in an environment variable:

:: Get the timestamp
for /f %%x in ('@timestamp') do set TIMESTAMP=%%x

:: Use it to generate a filename
for /r %%x in (.\processed\*) do move "%%~x" ".\archived\%%~nx-%TIMESTAMP%%%~xx"

I've just have a similar problem, a simple solution is to just use:

.click()

Any other solution will work if you refresh radio after calling function.

Here's what I used to get information on an undocumented (3rd-party) intent:

Bundle bundle = intent.getExtras();
if (bundle != null) {
    for (String key : bundle.keySet()) {
        Log.e(TAG, key + " : " + (bundle.get(key) != null ? bundle.get(key) : "NULL"));
    }
}

Make sure to check if bundle is null before the loop.

To be relative to the root directory, just start the URI with a /

<link type="text/css" rel="stylesheet" href="/style.css" />
<script src="/script.js" type="text/javascript"></script>

I think it's best to call join() on your threads when you expect them to die. I've taken some liberty with your code to make the loops end (you can add whatever cleanup needs are required to there as well). The variable die is checked for truth on each pass and when it's True then the program exits.

import threading
import time

class MyThread (threading.Thread):
    die = False
    def __init__(self, name):
        threading.Thread.__init__(self)
        self.name = name

    def run (self):
        while not self.die:
            time.sleep(1)
            print (self.name)

    def join(self):
        self.die = True
        super().join()

if __name__ == '__main__':
    f = MyThread('first')
    f.start()
    s = MyThread('second')
    s.start()
    try:
        while True:
            time.sleep(2)
    except KeyboardInterrupt:
        f.join()
        s.join()

By the looks of it you need to actually pass drawImage an image object like so

var canvas = document.getElementById("c");_x000D_
var ctx = canvas.getContext("2d");_x000D_
_x000D_
var image = new Image();_x000D_
image.onload = function() {_x000D_
  ctx.drawImage(image, 0, 0);_x000D_
};_x000D_

As Benjamin said in his answer, TC39 explicitly decided not to include this feature at least for ES2015. However, the consensus seems to be that they will add it in ES2016.

The syntax hasn't been decided yet, but there's a preliminary proposal for ES2016 that will allow you to declare static properties on a class.

Thanks to the magic of babel, you can use this today. Enable the class properties transform according to these instructions and you're good to go. Here's an example of the syntax:

class foo {
  static myProp = 'bar'
  someFunction() {
    console.log(this.myProp)
  }
}

This proposal is in a very early state, so be prepared to tweak your syntax as time goes on.

Since you are using C++11, lambda-expression is a nice&clean solution.

class blub {
    void test() {}
  public:
    std::thread spawn() {
      return std::thread( [this] { this->test(); } );
    }
};

since this-> can be omitted, it could be shorten to:

std::thread( [this] { test(); } )

or just (deprecated)

std::thread( [=] { test(); } )

import os
import os.path
import shutil

You find your current directory:

d = os.getcwd() #Gets the current working directory

Then you change one directory up:

os.chdir("..") #Go up one directory from working directory

Then you can get a tupple/list of all the directories, for one directory up:

o = [os.path.join(d,o) for o in os.listdir(d) if os.path.isdir(os.path.join(d,o))] # Gets all directories in the folder as a tuple

Then you can search the tuple for the directory you want and open the file in that directory:

for item in o:
    if os.path.exists(item + '\\testfile.txt'):
    file = item + '\\testfile.txt'

Then you can do stuf with the full file path 'file'

This solved my problem once in Windows:

subst X: "C:\Program files\MySQL\MySQL Server 5.5" 
gem install mysql2 -v 0.x.x --platform=ruby -- --with-mysql-dir=X: --with-mysql-lib=X:\lib\opt 
subst X: /D

If you know list comprehensions:

lines = [line[5:] for line in file.readlines() if line[:5] == "Path="]

Chrome specifically blocks local file access this way for security reasons.

Here's a workaround to enable the flag in Chrome (and open your system up to vulnerabilities):

c:\Program Files (x86)\google\chrome\Application\chrome.exe --allow-file-access-from-files

There is a performance increase in running compiled python. However when you run a .py file as an imported module, python will compile and store it, and as long as the .py file does not change it will always use the compiled version.

With any interpeted language when the file is used the process looks something like this:
1. File is processed by the interpeter.
2. File is compiled
3. Compiled code is executed.

obviously by using pre-compiled code you can eliminate step 2, this applies python, PHP and others.

Heres an interesting blog post explaining the differences http://julipedia.blogspot.com/2004/07/compiled-vs-interpreted-languages.html
And here's an entry that explains the Python compile process http://effbot.org/zone/python-compile.htm

Anaconda is a very large installation ~ 2 GB and is most useful for those users who are not familiar with installing modules or packages with other package managers.

Anaconda seems to be promoting itself as the official package manager of Jupyter. It's not. Anaconda bundles Jupyter, R, python, and many packages with its installation.

Anaconda is not necessary for installing Jupyter Lab or the R kernel. There is plenty of information available elsewhere for installing Jupyter Lab or Notebooks. There is also plenty of information elsewhere for installing R studio. The following shows how to install the R kernel directly from R Studio:

To install the R kernel, without Anaconda, start R Studio. In the R terminal window enter these three commands:

install.packages("devtools")
devtools::install_github("IRkernel/IRkernel")
IRkernel::installspec()

Done. Next time Jupyter is opened, the R kernel will be available.

There is no standard, so there is no guarantee. With that said, its common for the sitemap to be self labeled and on the root, like this:

example.com/sitemap.xml

Case is sensitive on some servers, so keep that in mind. If its not there, look in the robots file on the root:

example.com/robots.txt

If you don't see it listed in the robots file head to Google and search this:

site:example.com filetype:xml

This will limit the results to XML files on your target domain. At this point its trial-and-error and based on the specifics of the website you are working with. If you get several pages of results from the Google search phrase above then try to limit the results further:

filetype:xml site:example.com inurl:sitemap

or

filetype:xml site:example.com inurl:products

If you still can't find it you can right-click > "View Source" and do a search (aka: "control find" or Ctrl + F) for .xml to see if there is a reference to it in the code.

In case anyone needs to try and merge two dataframes together on the index (instead of another column), this also works!

T1 and T2 are dataframes that have the same indices

import pandas as pd
T1 = pd.merge(T1, T2, on=T1.index, how='outer')

P.S. I had to use merge because append would fill NaNs in unnecessarily.

Don't cast unless you must. There's nothign wrong with calling toString().

var checkbox = $( "#checkbox" );
checkbox.val( checkbox[0].checked ? "true" : "false" );

This will set the value of the checkbox to "true" or "false" (value property is a string), depending whether it's unchecked or checked.

What's happening is that you're bitten by this problem. Basically, what happened is that you didn't register your controllers explicitly in your container. Unity tries to resolve unregistered concrete types for you, but because it can't resolve it (caused by an error in your configuration), it return null. It is forced to return null, because Web API forces it to do so due to the IDependencyResolver contract. Since Unity returns null, Web API will try to create the controller itself, but since it doesn't have a default constructor it will throw the "Make sure that the controller has a parameterless public constructor" exception. This exception message is misleading and doesn't explain the real cause.

You would have seen a much clearer exception message if you registered your controllers explicitly, and that's why you should always register all root types explicitly.

But of course, the configuration error comes from you adding the second constructor to your DbContext. Unity always tries to pick the constructor with the most arguments, but it has no idea how to resolve this particular constructor.

So the real cause is that you are trying to use Unity's auto-wiring capabilities to create the DbContext. DbContext is a special type that shouldn't be auto-wired. It is a framework type and you should therefore fallback to registering it using a factory delegate:

container.Register<DashboardDbContext>(
    new InjectionFactory(c => new DashboardDbContext())); 

Although I like using the keyboard module to capture keyboard events, I don't like its record() function because it returns an array like [KeyboardEvent("A"), KeyboardEvent("~")], which I find kind of hard to read. So, to record keyboard events, I like to use the keyboard module and the threading module simultaneously, like this:

import keyboard
import string
from threading import *


# I can't find a complete list of keyboard keys, so this will have to do:
keys = list(string.ascii_lowercase)
"""
Optional code(extra keys):

keys.append("space_bar")
keys.append("backspace")
keys.append("shift")
keys.append("esc")
"""
def listen(key):
    while True:
        keyboard.wait(key)
        print("[+] Pressed",key)
threads = [Thread(target=listen, kwargs={"key":key}) for key in keys]
for thread in threads:
    thread.start()

If you are using android.app.ActionBar and android.app.Activity you should change the app theme in application tag:

< application
     android:theme="@android:style/Theme.Holo.Light">

Just for the sake of completeness, I invite you to think about it like this:

• There are lots of block elements (linebreaks before and after) defined in HTML, and lots of inline tags (no linebreaks).
• But in modern HTML all elements are supposed to have meanings: a <p> is a paragraph, an <li> is a list item, etc., and we're supposed to use the right tag for the right purpose -- not like in the old days when we indented using <blockquote> whether the content was a quote or not.
• So, what do you do when there is no meaning to the thing you're trying to do? There's no meaning to a 400px-wide column, is there? You just want your column of text to be 400px wide because that suits your design.
• For this reason, they added two more elements to HTML: the generic, or meaningless elements <div> and <span>, because otherwise, people would go back to abusing the elements which do have meanings.
