You only get that message if you try to use Designer or diagrams. If you use t-SQL it works fine:

Select * 

into newdb.dbo.newtable
from olddb.dbo.yourtable

where olddb.dbo.yourtable has been created in 2008 exactly as you want the table to be in 2012

Actually, as long as the parent element is positioned, you can set the child's height to 100%. Namely, in case you don't want the parent to be absolutely positioned. Let me explain further:

<style>
    #outer2 {
        padding-left: 23px;
        position: relative; 
        height:auto; 
        width:200px; 
        border: 1px solid red; 
    }
    #inner2 {
        left:0;
        position:absolute; 
        height:100%; 
        width:20px; 
        border: 1px solid black; 
    }
</style>

<div id='outer2'>
    <div id='inner2'>
    </div>
</div>

You have to do this:

class Bar : public Foo
{
    // ...
}

The default inheritance type of a class in C++ is private, so any public and protected members from the base class are limited to private. struct inheritance on the other hand is public by default.

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(Environment.getDataDirectory()
                    + "/Robotium-Screenshots/");
            /*
             * this checks to see if there are any previous test photo files
             * if there are any photos, they are deleted for the sake of
             * memory
             */
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length != 0) {
                    for (int ii = 0; ii <= dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                }
            }
            // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            // if phone DOES have sd card
        } else if (Environment.getExternalStorageState() != null) {
            // search for directory on SD card
            directory = new File(Environment.getExternalStorageDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(
                    Environment.getExternalStorageDirectory()
                            + "/Robotium-Screenshots/");
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length > 0) {
                    for (int ii = 0; ii < dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                    dirFiles = null;
                }
            }
            // if no directory exists, create new directory to store test
            // results
            if (!directory.exists()) {
                directory.mkdir();
            }
        }// end of SD card checking

add permissions on your manifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

Happy coding..

This is an alternative answer for the case where tqdm_notebook doesn't work for you.

Given the following example:

from time import sleep
from tqdm import tqdm

values = range(3)
with tqdm(total=len(values)) as pbar:
    for i in values:
        pbar.write('processed: %d' %i)
        pbar.update(1)
        sleep(1)

The output would look something like this (progress would show up red):

  0%|          | 0/3 [00:00<?, ?it/s]
processed: 1
 67%|¦¦¦¦¦¦?   | 2/3 [00:01<00:00,  1.99it/s]
processed: 2
100%|¦¦¦¦¦¦¦¦¦¦| 3/3 [00:02<00:00,  1.53it/s]
processed: 3

The problem is that the output to stdout and stderr are processed asynchronously and separately in terms of new lines.

If say Jupyter receives on stderr the first line and then the "processed" output on stdout. Then once it receives an output on stderr to update the progress, it wouldn't go back and update the first line as it would only update the last line. Instead it will have to write a new line.

Workaround 1, writing to stdout

One workaround would be to output both to stdout instead:

import sys
from time import sleep
from tqdm import tqdm

values = range(3)
with tqdm(total=len(values), file=sys.stdout) as pbar:
    for i in values:
        pbar.write('processed: %d' % (1 + i))
        pbar.update(1)
        sleep(1)

The output will change to (no more red):

processed: 1   | 0/3 [00:00<?, ?it/s]
processed: 2   | 0/3 [00:00<?, ?it/s]
processed: 3   | 2/3 [00:01<00:00,  1.99it/s]
100%|¦¦¦¦¦¦¦¦¦¦| 3/3 [00:02<00:00,  1.53it/s]

Here we can see that Jupyter doesn't seem to clear until the end of the line. We could add another workaround for that by adding spaces. Such as:

import sys
from time import sleep
from tqdm import tqdm

values = range(3)
with tqdm(total=len(values), file=sys.stdout) as pbar:
    for i in values:
        pbar.write('processed: %d%s' % (1 + i, ' ' * 50))
        pbar.update(1)
        sleep(1)

Which gives us:

processed: 1                                                  
processed: 2                                                  
processed: 3                                                  
100%|¦¦¦¦¦¦¦¦¦¦| 3/3 [00:02<00:00,  1.53it/s]

Workaround 2, set description instead

It might in general be more straight forward not to have two outputs but update the description instead, e.g.:

import sys
from time import sleep
from tqdm import tqdm

values = range(3)
with tqdm(total=len(values), file=sys.stdout) as pbar:
    for i in values:
        pbar.set_description('processed: %d' % (1 + i))
        pbar.update(1)
        sleep(1)

With the output (description updated while it's processing):

processed: 3: 100%|¦¦¦¦¦¦¦¦¦¦| 3/3 [00:02<00:00,  1.53it/s]

Conclusion

You can mostly get it to work fine with plain tqdm. But if tqdm_notebook works for you, just use that (but then you'd probably not read that far).

Also note ? along with a character, will return the ASCII character code for A

For example:

?F # => will return 70

Alternately in ruby 1.8 you can do:

"F"[0]

or in ruby 1.9:

"F".ord

Also notice that ?F will return the string "F", so in order to make the code shorter, you can also use ?F.ord in Ruby 1.9 to get the same result as "F".ord.

You can use this :

$this->db->select('*');
$this->db->from('mytable');
$this->db->where(name,'Joe');
$bind = array('boss', 'active');
$this->db->where_in('status', $bind);

I encountered the same problem. The easiest thing is to install the free Visual Studio Community 2015 as answered in this question Is MFC only available with Visual Studio, and not Visual C++ Express?

I'm not 100% sure if this works in all cases (needs at least Java 1.5):

import java.lang.reflect.Field;
import java.lang.reflect.ParameterizedType;
import java.lang.reflect.Type;
import java.util.HashMap;
import java.util.Map;

public class Main 
{
    public class A
    {   
    }

    public class B extends A
    {       
    }


    public Map<A, B> map = new HashMap<Main.A, Main.B>();

    public static void main(String[] args) 
    {

        try
        {
            Field field = Main.class.getField("map");           
            System.out.println("Field " + field.getName() + " is of type " + field.getType().getSimpleName());

            Type genericType = field.getGenericType();

            if(genericType instanceof ParameterizedType)
            {
                ParameterizedType type = (ParameterizedType) genericType;               
                Type[] typeArguments = type.getActualTypeArguments();

                for(Type typeArgument : typeArguments) 
                {   
                    Class<?> classType = ((Class<?>)typeArgument);                  
                    System.out.println("Field " + field.getName() + " has a parameterized type of " + classType.getSimpleName());
                }
            }
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }    
}

This will output:

Field map is of type Map
Field map has a parameterized type of A
Field map has a parameterized type of B

I understand that this question is old, but there is a good solution for it in HTML5. You can wrap it all in a <figure></figure> tag. The code would look something like this:

<div id="wrapper">
<figure>

<a href="mailto:[email protected]">
<img id="fblogo" border="0" alt="Mail" src="http://olympiahaacht.be/wp- 
content/uploads/2012/07/email-icon-e1343123697991.jpg"/>
</a>

<a href="https://www.facebook.com/OlympiaHaacht" target="_blank">
<img id="fblogo" border="0" alt="Facebook" src="http://olympiahaacht.be/wp- 
content/uploads/2012/04/FacebookButtonRevised-e1334605872360.jpg"/>
</a>

</figure>
</div>

and the CSS:

#wrapper{
 text-align:center;
}

With Internet Explorer you often have to specify the Pragma: public header as well for the download to function properly..

header('Pragma: public');

Just my 2 cents..

Nobody suggested Vagrant yet, so here it is, Vagrant box for OSX

vagrant init https://vagrant-osx.nyc3.digitaloceanspaces.com/osx-sierra-0.3.1.box
vagrant up

and you have a MACOS virtual machine. But according to Apple's EULA, you still need to run it on MacOS hardware :D But anywhere, here's one to all of you geeks who wiped MacOS and installed Ubuntu :D

Unfortunately, you can't run the editors from inside using SSH X-forwarding option.

You can use & in place of &

If you do not want to define a separate class for nested json , Defining nested json object as JsonNode should work ,for example :

{"id":2,"socket":"0c317829-69bf-43d6-b598-7c0c550635bb","type":"getDashboard","data":{"workstationUuid":"ddec1caa-a97f-4922-833f-632da07ffc11"},"reply":true}

@JsonProperty("data")
    private JsonNode data;

You can user BindingAdapter like this:

Java

@BindingAdapter("setBackground")
public static void setBackground(WebView view,@ColorRes int resId) {
        view.setBackgroundColor(view.getContext().getResources().getColor(resId));
        view.setLayerType(WebView.LAYER_TYPE_SOFTWARE, null);
}

XML:

<layout >

    <data>

        <import type="com.tdk.sekini.R" />


    </data>

       <WebView
            ...
            app:setBackground="@{R.color.grey_10_transparent}"/>

</layout>

Resources

<color name="grey_10_transparent">#11e6e6e6</color>

char *arr; above statement implies that arr is a character pointer and it can point to either one character or strings of character

& char arr[]; above statement implies that arr is strings of character and can store as many characters as possible or even one but will always count on '\0' character hence making it a string ( e.g. char arr[]= "a" is similar to char arr[]={'a','\0'} )

But when used as parameters in called function, the string passed is stored character by character in formal arguments making no difference.

By using T-SQL and cursors like this :

DECLARE @MyCursor CURSOR;
DECLARE @MyField YourFieldDataType;
BEGIN
    SET @MyCursor = CURSOR FOR
    select top 1000 YourField from dbo.table
        where StatusID = 7      

    OPEN @MyCursor 
    FETCH NEXT FROM @MyCursor 
    INTO @MyField

    WHILE @@FETCH_STATUS = 0
    BEGIN
      /*
         YOUR ALGORITHM GOES HERE   
      */
      FETCH NEXT FROM @MyCursor 
      INTO @MyField 
    END; 

    CLOSE @MyCursor ;
    DEALLOCATE @MyCursor;
END;

There are three ways to fetch multiple rows returned by PDO statement.

The simplest one is just to iterate over PDOStatement itself:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// iterating over a statement
foreach($stmt as $row) {
    echo $row['name'];
}

another one is to fetch rows using fetch() method inside a familiar while statement:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    echo $row['name'];
}

but for the modern web application we should have our datbase iteractions separated from output and thus the most convenient method would be to fetch all rows at once using fetchAll() method:

$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// fetching rows into array
$data = $stmt->fetchAll();

or, if you need to preprocess some data first, use the while loop and collect the data into array manually

$result = [];
$stmt = $pdo->prepare("SELECT * FROM auction WHERE name LIKE ?")
$stmt->execute(array("%$query%"));
// using while
while($row = $stmt->fetch()) {
    $result[] = [
        'newname' => $row['oldname'],
        // etc
    ];
}

and then output them in a template:

<ul>
<?php foreach($data as $row): ?>
    <li><?=$row['name']?></li>
<?php endforeach ?>
</ul>

Note that PDO supports many sophisticated fetch modes, allowing fetchAll() to return data in many different formats.

To display a value nicely, you can use the pprint module. The easiest way to dump all variables with it is to do

from pprint import pprint

pprint(globals())
pprint(locals())

If you are running in CGI, a useful debugging feature is the cgitb module, which displays the value of local variables as part of the traceback.

hasOwnProperty "can be used to determine whether an object has the specified property as a direct property of that object; unlike the in operator, this method does not check down the object's prototype chain."

So most probably, for what seems by your question, you don't want to use hasOwnProperty, which determines if the property exists as attached directly to the object itself,.

If you want to determine if the property exists in the prototype chain, you may want to use it like:

if (prop in object) { // Do something }

jQuery(window).load(function () {
    alert('page is loaded');

    setTimeout(function () {
        alert('page is loaded and 1 minute has passed');   
    }, 60000);

});

Or http://jsfiddle.net/tangibleJ/fLLrs/1/

See also http://api.jquery.com/load-event/ for an explanation on the jQuery(window).load.

Update

A detailed explanation on how javascript loading works and the two events DOMContentLoaded and OnLoad can be found on this page.

DOMContentLoaded: When the DOM is ready to be manipulated. jQuery's way of capturing this event is with jQuery(document).ready(function () {});.

OnLoad: When the DOM is ready and all assets - this includes images, iframe, fonts, etc - have been loaded and the spinning wheel / hour class disappear. jQuery's way of capturing this event is the above mentioned jQuery(window).load.

If you want to get current working directory use getcwd()

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

__FILE__ will return path with filename for example on XAMPP C:\xampp\htdocs\index.php instead of C:\xampp\htdocs\

Just Simply use

use css code: text-transform: uppercase;

@tableName Table variables are alive for duration of the script running only i.e. they are only session level objects.

To test this, open two query editor windows under sql server management studio, and create table variables with same name but different structures. You will get an idea. The @tableName object is thus temporary and used for our internal processing of data, and it doesn't contribute to the actual database structure.

There is another type of table object which can be created for temporary use. They are #tableName objects declared like similar create statement for physical tables:

Create table #test (Id int, Name varchar(50))

This table object is created and stored in temp database. Unlike the first one, this object is more useful, can store large data and takes part in transactions etc. These tables are alive till the connection is open. You have to drop the created object by following script before re-creating it.

IF OBJECT_ID('tempdb..#test') IS NOT NULL
  DROP TABLE #test 

Hope this makes sense !

I'll try to answer several key points: this is from long Hibernate/ persistence experience including several major applications.

Entity Class: implement Serializable?

Keys needs to implement Serializable. Stuff that's going to go in the HttpSession, or be sent over the wire by RPC/Java EE, needs to implement Serializable. Other stuff: not so much. Spend your time on what's important.

Constructors: create a constructor with all required fields of the entity?

Constructor(s) for application logic, should have only a few critical "foreign key" or "type/kind" fields which will always be known when creating the entity. The rest should be set by calling the setter methods -- that's what they're for.

Avoid putting too many fields into constructors. Constructors should be convenient, and give basic sanity to the object. Name, Type and/or Parents are all typically useful.

OTOH if application rules (today) require a Customer to have an Address, leave that to a setter. That is an example of a "weak rule". Maybe next week, you want to create a Customer object before going to the Enter Details screen? Don't trip yourself up, leave possibility for unknown, incomplete or "partially entered" data.

Constructors: also, package private default constructor?

Yes, but use 'protected' rather than package private. Subclassing stuff is a real pain when the necessary internals are not visible.

Fields/Properties

Use 'property' field access for Hibernate, and from outside the instance. Within the instance, use the fields directly. Reason: allows standard reflection, the simplest & most basic method for Hibernate, to work.

As for fields 'immutable' to the application -- Hibernate still needs to be able to load these. You could try making these methods 'private', and/or put an annotation on them, to prevent application code making unwanted access.

Note: when writing an equals() function, use getters for values on the 'other' instance! Otherwise, you'll hit uninitialized/ empty fields on proxy instances.

Protected is better for (Hibernate) performance?

Unlikely.

Equals/HashCode?

This is relevant to working with entities, before they've been saved -- which is a thorny issue. Hashing/comparing on immutable values? In most business applications, there aren't any.

A customer can change address, change the name of their business, etc etc -- not common, but it happens. Corrections also need to be possible to make, when the data was not entered correctly.

The few things that are normally kept immutable, are Parenting and perhaps Type/Kind -- normally the user recreates the record, rather than changing these. But these do not uniquely identify the entity!

So, long and short, the claimed "immutable" data isn't really. Primary Key/ ID fields are generated for the precise purpose, of providing such guaranteed stability & immutability.

You need to plan & consider your need for comparison & hashing & request-processing work phases when A) working with "changed/ bound data" from the UI if you compare/hash on "infrequently changed fields", or B) working with "unsaved data", if you compare/hash on ID.

Equals/HashCode -- if a unique Business Key is not available, use a non-transient UUID which is created when the entity is initialized

Yes, this is a good strategy when required. Be aware that UUIDs are not free, performance-wise though -- and clustering complicates things.

Equals/HashCode -- never refer to related entities

"If related entity (like a parent entity) needs to be part of the Business Key then add a non insertable, non updatable field to store the parent id (with the same name as the ManytoOne JoinColumn) and use this id in the equality check"

Sounds like good advice.

Hope this helps!

A CASE statement is an expression, just like a boolean comparison. That means the 'AND' needs to go before the 'CASE' statement, not within it.:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)

AND -- Added the "AND" here

CASE WHEN @day = 'Monday' THEN (Monday = 1)   -- Removed "AND" 
    WHEN @day = 'Tuesday' THEN (Tuesday = 1)  -- Removed "AND" 
    ELSE AND (Wednesday = 1) 
END

Split the screen and run command term ++curwin to run the terminal inside the Vim buffer. Following command does both and worked for me:

:bo 10sp | term ++curwin

Function strlen shows the number of character before \0 and using it for std::string may report wrong length.

strlen(str.c_str()); // It may return wrong length.

In C++, a string can contain \0 within the characters but C-style-zero-terminated strings can not but at the end. If the std::string has a \0 before the last character then strlen reports a length less than the actual length.

Try to use .length() or .size(), I prefer second one since another standard containers have it.

str.size()

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

This is one example where using prepared statements really saves you some trouble.

In MySQL, in order to insert a null value, you must specify it at INSERT time or leave the field out which requires additional branching:

INSERT INTO table2 (f1, f2)
  VALUES ('String Value', NULL);

However, if you want to insert a value in that field, you must now branch your code to add the single quotes:

INSERT INTO table2 (f1, f2)
  VALUES ('String Value', 'String Value');

Prepared statements automatically do that for you. They know the difference between string(0) "" and null and write your query appropriately:

$stmt = $mysqli->prepare("INSERT INTO table2 (f1, f2) VALUES (?, ?)");
$stmt->bind_param('ss', $field1, $field2);

$field1 = "String Value";
$field2 = null;

$stmt->execute();

It escapes your fields for you, makes sure that you don't forget to bind a parameter. There is no reason to stay with the mysql extension. Use mysqli and it's prepared statements instead. You'll save yourself a world of pain.

You have to increase client_max_body_size in nginx.conf file. This is the basic step. But if your backend laravel then you have to do some changes in the php.ini file as well. It depends on your backend. Below I mentioned file location and condition name.

sudo vim /etc/nginx/nginx.conf.

After open the file adds this into HTTP section.

client_max_body_size 100M;

[Environment]::UserName returns just the user name. E.g. bob [System.Security.Principal.WindowsIdentity]::GetCurrent().Name returns the user name, prefixed by its domain where appropriate. E.g. SOMEWHERENICE\bob

One way, as suggested in this post, is to mention version in pip as:

pip install -Iv MySQL_python==1.2.2

i.e. Use == and mention the version number to install only that version. -I, --ignore-installed ignores already installed packages.

Simply return it:

<html>
    <?php
        $num = 1;
        echo $num;
    ?>
    <input type="button"
       name="lol" 
       value="Click to increment"
       onclick="Inc()" />
    <br>
    <script>
        function Inc()
        {
            Return <?php
            $num = 2;
            echo $num;
            ?>;
        }
    </script>

• A shade is produced by "darkening" a hue or "adding black"
• A tint is produced by "ligthening" a hue or "adding white"

Creating a tint or a shade

Depending on your Color Model, there are different methods to create a darker (shaded) or lighter (tinted) color:

• RGB:

  • To shade:

    newR = currentR * (1 - shade_factor)
    newG = currentG * (1 - shade_factor)
    newB = currentB * (1 - shade_factor)
    

  • To tint:

    newR = currentR + (255 - currentR) * tint_factor
    newG = currentG + (255 - currentG) * tint_factor
    newB = currentB + (255 - currentB) * tint_factor
    

  • More generally, the color resulting in layering a color RGB(currentR,currentG,currentB) with a color RGBA(aR,aG,aB,alpha) is:

    newR = currentR + (aR - currentR) * alpha
    newG = currentG + (aG - currentG) * alpha
    newB = currentB + (aB - currentB) * alpha
    

  where (aR,aG,aB) = black = (0,0,0) for shading, and (aR,aG,aB) = white = (255,255,255) for tinting

• HSV or HSB:

  • To shade: lower the Value / Brightness or increase the Saturation
  • To tint: lower the Saturation or increase the Value / Brightness
• HSL:
  • To shade: lower the Lightness
  • To tint: increase the Lightness

There exists formulas to convert from one color model to another. As per your initial question, if you are in RGB and want to use the HSV model to shade for example, you can just convert to HSV, do the shading and convert back to RGB. Formula to convert are not trivial but can be found on the internet. Depending on your language, it might also be available as a core function :

• RGB to HSV color in javascript?
• Convert RGB value to HSV

Comparing the models

• RGB has the advantage of being really simple to implement, but:
  • you can only shade or tint your color relatively
  • you have no idea if your color is already tinted or shaded
• HSV or HSB is kind of complex because you need to play with two parameters to get what you want (Saturation & Value / Brightness)
• HSL is the best from my point of view:
  • supported by CSS3 (for webapp)
  • simple and accurate:
    • 50% means an unaltered Hue
    • >50% means the Hue is lighter (tint)
    • <50% means the Hue is darker (shade)
  • given a color you can determine if it is already tinted or shaded
  • you can tint or shade a color relatively or absolutely (by just replacing the Lightness part)

• If you want to learn more about this subject: Wiki: Colors Model
• For more information on what those models are: Wikipedia: HSL and HSV

You have to define the compare first. There are 3 ways to do that:

1. use class
2. use struct (which is same as class)
3. use lambda function.

It's easy to use class/struct because easy to declare just write this line of code above your executing code

struct compare{
  public:
  bool operator()(Node& a,Node& b) // overloading both operators 
  {
      return a.w < b.w: // if you want increasing order;(i.e increasing for minPQ)
      return a.w > b.w // if you want reverse of default order;(i.e decreasing for minPQ)
   }
};

Calling code:

priority_queue<Node,vector<Node>,compare> pq;

you can simply use this:

Map<String, String[]> parameters = request.getParameterMap();

That should work fine

Something like this.setExtendedState(this.getExtendedState() | this.MAXIMIZED_BOTH);

import java.awt.*;
import javax.swing.*;

public class Test extends JFrame
{
    public Test()
    {
        GraphicsEnvironment env =
GraphicsEnvironment.getLocalGraphicsEnvironment();
        this.setMaximizedBounds(env.getMaximumWindowBounds());
        this.setExtendedState(this.getExtendedState() | this.MAXIMIZED_BOTH);
    }

    public static void main(String[] args)
    {
        JFrame.setDefaultLookAndFeelDecorated(true);

        Test t = new Test();
        t.setVisible(true);
    }
}

This code should do the same as your new routine, working with the correct multi-dimensional array..

 $arr = array(
  'string1' => array('a' => '', 'b' => '', 'c' => ''),
  'string2' => array('a' => '', 'b' => '', 'c' => ''),
  'string3' => array('a' => '', 'b' => '', 'c' => '')
 );

 echo 'Index of "string2" = '. array_search('string2', array_keys($arr));

You can try this code into your activity

    private void startWebView(WebView webView,String url) {
 webView.setWebViewClient(new WebViewClient() {
            ProgressDialog progressDialog;

            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return false;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }

            public void onLoadResource (WebView view, String url) {

                    if (progressDialog == null) {
                        progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
                        progressDialog.setMessage("Loading...");
                        progressDialog.show();
                    }

            }
            public void onPageFinished(WebView view, String url) {
                try{
                    if (progressDialog.isShowing()) {
                        progressDialog.dismiss();
                        progressDialog = null;
                    }

                }catch(Exception exception){
                    exception.printStackTrace();
                }
            }

        });

        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl(url);
    }

Call this method using this way:

startWebView(web_view,"Your Url");

Sometimes if URL is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason progress bar will not dismis. To solve this issue see my this Answer.

Thanks :)

For windows 8, just type "py".

FileReader reads from files on the file system.

Perhaps you intended to use something like this to load a file from the class path

// this will look in src/main/resources before building and myjar.jar! after building.
InputStream is = MyClass.class.getClassloader()
                     .getResourceAsStream("config.txt");

Or you could extract the file from the jar before reading it.

As a general (see Stackblitz here: https://stackblitz.com/edit/angular-gh2rjx):

HTML

<select [(ngModel)]="selectedOption">
   <option *ngFor="let o of options">
      {{o.name}}
   </option>
</select>
<button (click)="print()">Click me</button>

<p>Selected option: {{ selectedOption }}</p>
<p>Button output: {{ printedOption }}</p>

Typescript

export class AppComponent {
  selectedOption: string;
  printedOption: string;

  options = [
    { name: "option1", value: 1 },
    { name: "option2", value: 2 }
  ]
  print() {
    this.printedOption = this.selectedOption;
  }
}

In your specific case you can use ngModel like this:

<form class="form-inline" (ngSubmit)="HelloCorp()">
     <div class="select">
         <select [(ngModel)]="corporationObj" class="form-control col-lg-8" #corporation required>
             <option *ngFor="let corporation of corporations"></option>    
         </select>
         <button type="submit" class="btn btn-primary manage">Submit</button>
     </div>
</form>

HelloCorp() {
  console.log("My input: ", corporationObj);
}

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

This is a never ending story that reflect the limits (an myth) of "interoperability and portability over all".

What the program should return to indicate "success" should be defined by who is receiving the value (the Operating system, or the process that invoked the program) not by a language specification.

But programmers likes to write code in "portable way" and hence they invent their own model for the concept of "operating system" defining symbolic values to return.

Now, in a many-to-many scenario (where many languages serve to write programs to many system) the correspondence between the language convention for "success" and the operating system one (that no one can grant to be always the same) should be handled by the specific implementation of a library for a specific target platform.

But - unfortunatly - these concept where not that clear at the time the C language was deployed (mainly to write the UNIX kernel), and Gigagrams of books where written by saying "return 0 means success", since that was true on the OS at that time having a C compiler.

From then on, no clear standardization was ever made on how such a correspondence should be handled. C and C++ has their own definition of "return values" but no-one grant a proper OS translation (or better: no compiler documentation say anything about it). 0 means success if true for UNIX - LINUX and -for independent reasons- for Windows as well, and this cover 90% of the existing "consumer computers", that - in the most of the cases - disregard the return value (so we can discuss for decades, bu no-one will ever notice!)

Inside this scenario, before taking a decision, ask these questions: - Am I interested to communicate something to my caller about my existing? (If I just always return 0 ... there is no clue behind the all thing) - Is my caller having conventions about this communication ? (Note that a single value is not a convention: that doesn't allow any information representation)

If both of this answer are no, probably the good solution is don't write the main return statement at all. (And let the compiler to decide, in respect to the target is working to).

If no convention are in place 0=success meet the most of the situations (and using symbols may be problematic, if they introduce a convention).

If conventions are in place, ensure to use symbolic constants that are coherent with them (and ensure convention coherence, not value coherence, between platforms).

/*

If your delimiters are slash-based, escape it:

\/*

* means "0 or more of the previous repeatable pattern", which can be a single character, a character class or a group.

 ;(function($){
        // your code
    })(jQuery);

Place your js code inside the closure above , it should solve the problem.

You should add overflow property like following:

.itemconfiguration
    {   
        height: 300px; 
        overflow-y:auto;
        width:215px;
        float:left;
        position:relative;
        margin-left:-5px;
    }

A contract is: If two objects are equal then they should have the same hashcode and if two objects are not equal then they may or may not have same hash code.

Try using your object as key in HashMap (edited after comment from joachim-sauer), and you will start facing trouble. A contract is a guideline, not something forced upon you.

Can be pretty easily done assuming you're using jQuery and css3:

http://jsfiddle.net/S7JDU/8/

HTML:

<div id="clicker">Click Here</div>
<div id="rotating"></div>

CSS:

#clicker { 
    width: 100px; 
    height: 100px; 
    background-color: Green; 
}

#rotating { 
    width: 100px; 
    height: 100px; 
    background-color: Red; 
    margin-top: 50px; 
    -webkit-transition: all 0.3s ease-in-out;
    -moz-transition: all 0.3s ease-in-out;
    -o-transition: all 0.3s ease-in-out;
    transition: all 0.3s ease-in-out;
}

.rotated { 
    transform:rotate(25deg); 
    -webkit-transform:rotate(25deg); 
    -moz-transform:rotate(25deg); 
    -o-transform:rotate(25deg); 
}

JS:

$(document).ready(function() {
    $('#clicker').click(function() {
        $('#rotating').toggleClass('rotated');
    });
});

I currently follow the policy (that so many are saying) that classes shouldn't actively throw exceptions from their destructors but should instead provide a public "close" method to perform the operation that could fail...

...but I do believe destructors for container-type classes, like a vector, should not mask exceptions thrown from classes they contain. In this case, I actually use a "free/close" method that calls itself recursively. Yes, I said recursively. There's a method to this madness. Exception propagation relies on there being a stack: If a single exception occurs, then both the remaining destructors will still run and the pending exception will propagate once the routine returns, which is great. If multiple exceptions occur, then (depending on the compiler) either that first exception will propagate or the program will terminate, which is okay. If so many exceptions occur that the recursion overflows the stack then something is seriously wrong, and someone's going to find out about it, which is also okay. Personally, I err on the side of errors blowing up rather than being hidden, secret, and insidious.

The point is that the container remains neutral, and it's up to the contained classes to decide whether they behave or misbehave with regard to throwing exceptions from their destructors.

What is the best/simplest library to use in order to read in values from this file?

As you're asking for the simplest library, I feel obliged to add an approach quite different to that in Guillaume's top-voted answer. (Of the other answers, sjbotha's JDOM mention is closest to what I suggest).

I've come to think that for XML handling in Java, using the standard JDK tools is certainly not the simplest way, and that only in some circumstances (such as not being able to use 3rd party libraries, for some reason) it is the best way.

Instead, consider using a good XML library, such as XOM. Here's how to read an XML file into a nu.xom.Document object:

import nu.xom.Builder;
import nu.xom.Document;
import java.io.File;

[...]

File file = new File("some/path");
Document document = new Builder().build(file);

So, this was just a little bit simpler, as reading the file into org.w3c.dom.Document wasn't very complicated either, in the "pure JDK" approach. But the advantages of using a good library only start here! Whatever you're doing with your XML, you'll often get away with much simpler solutions, and less of your own code to maintain, when using a library like XOM. As examples, consider this vs. this, or this vs. this, or this post containing both XOM and W3C DOM examples.

Others will provide counter-arguments (like these) for why sticking to Java's standard XML APIs may be worth it - these probably have merit, at least in some cases, although personally I don't subscribe to all of them. In any case, when choosing one way or the other, it's good to be aware of both sides of the story.

(This answer is part of my evaluation of XOM, which is a strong contender in my quest for finding the best Java XML library to replace dom4j.)

Text nodes cannot have margins or any other style applied to them, so anything you need style applied to must be in an element. If you want some of the text inside of your element to be styled differently, wrap it in a span or div, for example.

I have struggled with this problem since I don’t know why my droplevel() function does not work. Work through several and learn that ‘a’ in your table is columns name and ‘b’, ‘c’ are index. Do like this will help

df.columns.name = None
df.reset_index() #make index become label

CONCAT functions sometimes not work with older postgreSQL version

see what I used to solve problem without using CONCAT

 u.first_name || ' ' || u.last_name as user,

Or also you can use

 "first_name" || ' ' || "last_name" as user,

in second case I used double quotes for first_name and last_name

Hope this will be useful, thanks

$('#my_select option:selected').attr('id');

The best an easiest solution I found is https://github.com/billziss-gh/sshfs-win, connected servers shows up as a fully functioning network drives. This is not a 'Dokany' or 'dokan' based solution which from experiance seems more stable and performant, also see WinFsp Performance Testing.

Please note previously this answer stated, https://github.com/Foreveryone-cz/win-sshfs and before that http://www.swish-sftp.org/ but I no longer use any of them, first one stopped working second one created drives not fully supported in all programs.

Yes, with set_index you can make Locality your row index.

data.set_index('Locality', inplace=True)

If inplace=True is not provided, set_index returns the modified dataframe as a result.

Example:

> import pandas as pd
> df = pd.DataFrame([['ABBOTSFORD', 427000, 448000],
                     ['ABERFELDIE', 534000, 600000]],
                    columns=['Locality', 2005, 2006])

> df
     Locality    2005    2006
0  ABBOTSFORD  427000  448000
1  ABERFELDIE  534000  600000

> df.set_index('Locality', inplace=True)
> df
              2005    2006
Locality                  
ABBOTSFORD  427000  448000
ABERFELDIE  534000  600000

> df.loc['ABBOTSFORD']
2005    427000
2006    448000
Name: ABBOTSFORD, dtype: int64

> df.loc['ABBOTSFORD'][2005]
427000

> df.loc['ABBOTSFORD'].values
array([427000, 448000])

> df.loc['ABBOTSFORD'].tolist()
[427000, 448000]

As long as pip lives within the scripts folder you can run

python -m pip ....

This will tell python to get pip from inside the scripts folder. This is also a good way to have both python2.7 and pyhton3.5 on you computer and have them in different locations. I currently have both python2 and pyhton3 installed on windows. When I type python it defaults to python2. But if I type python3 I can use python3. (I also had to change the python.exe file for python3 to "python3.exe")If I need to install flask for python 2 I can run

python -m pip install flask

and it will be installed in the pyhton2 folder, but if I need flask for python 3 I run:

python3 -m pip install flask

and I now have it in the python3 folder

I install go launcher on mine, (Windows 8)=> preferences => Screens => Screen orientation => vertical (disable QWE keyboard)

There's no need to use replace for this.

What you have is a encoded string (using the string_escape encoding) and you want to decode it:

>>> s = r"Escaped\nNewline"
>>> print s
Escaped\nNewline
>>> s.decode('string_escape')
'Escaped\nNewline'
>>> print s.decode('string_escape')
Escaped
Newline
>>> "a\\nb".decode('string_escape')
'a\nb'

In Python 3:

>>> import codecs
>>> codecs.decode('\\n\\x21', 'unicode_escape')
'\n!'

Both are 0-based, but the start is inclusive and the end is exclusive. This ensures the resulting string is of length start - end.

To make life easier for substring operation, imagine that characters are between indexes.

0 1 2 3 4 5 6 7 8 9 10  <- available indexes for substring 
 u n i v E R S i t y
        ?     ?
      start  end --> range of "E R S"

Quoting the docs:

The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex.

I don't know about y'all but for my own lazy purposes I just got the text fields from 'document' by ID and set the values as parameters to my back-end JS function:

//index.js_x000D_
_x000D_
      <TextField_x000D_
        id="field1"_x000D_
        ..._x000D_
      />_x000D_
_x000D_
      <TextField_x000D_
        id="field2"_x000D_
        ..._x000D_
      />_x000D_
_x000D_
      <Button_x000D_
      ..._x000D_
      onClick={() => { printIt(document.getElementById('field1').value,_x000D_
      document.getElementById('field2').value)    _x000D_
      }}>_x000D_
_x000D_
_x000D_
//printIt.js_x000D_
_x000D_
export function printIt(text1, text2) {_x000D_
console.log('on button clicked');_x000D_
alert(text1);_x000D_
alert(text2);_x000D_
};

It works just fine.

You might sort the helper[] array directly:

java.util.Arrays.sort(helper, 1, helper.length);

Sorts the array from index 1 to the end. Leaves the first item at index 0 untouched.

See Arrays.sort(Object[] a, int fromIndex, int toIndex)

Change The "Virtual PC.exe" to a name without space like "VirtualPC.exe" in the folder. When you write start "path" with "" the CMD starts a new cmd window with the path as the title. Change the name to a name without space,write this on Notepad and after this save like Name.cmd or Name.bat:

CD\
CD Program Files
CD Microsoft Virtual PC
start VirtualPC.exe
timeout 2
exit

This command will redirect the CMD to the folder,start the VirualPC.exe,wait 2 seconds and exit.

Also you can try zenity !

user=$(zenity --entry --text 'Please enter the username:') || exit 1

In JavaScript this refers to the element containing the action. For example, if you have a function called hide():

function hide(element){
   element.style.display = 'none';
}

Calling hide with this will hide the element. It returns only the element clicked, even if it is similar to other elements in the DOM.

For example, you may have this clicking a number in the HTML below will only hide the bullet point clicked.

<ul>
  <li class="bullet" onclick="hide(this);">1</li>
  <li class="bullet" onclick="hide(this);">2</li>
  <li class="bullet" onclick="hide(this);">3</li>
  <li class="bullet" onclick="hide(this);">4</li>
</ul>

Highlight table name in the console and press ALT+F1

Well, your addActiveClass needs to know what was clicked. Something like this could work (notice that I've added the information which divs are active as a state array, and that onClick now passes the information what was clicked as a parameter after which the state is accordingly updated - there are certainly smarter ways to do it, but you get the idea).

class Test extends Component(){

  constructor(props) {
    super(props);
    this.state = {activeClasses: [false, false, false]};
    this.addActiveClass= this.addActiveClass.bind(this);
  }

  addActiveClass(index) {
    const activeClasses = [...this.state.activeClasses.slice(0, index), !this.state.activeClasses[index], this.state.activeClasses.slice(index + 1)].flat();
    this.setState({activeClasses});
  }

  render() {
    const activeClasses = this.state.activeClasses.slice();
    return (
      <div>
        <div className={activeClasses[0]? "active" : "inactive"} onClick={() => this.addActiveClass(0)}>
          <p>0</p>
        </div>
        <div className={activeClasses[1]? "active" : "inactive"} onClick={() => this.addActiveClass(1)}>
          <p>1</p>
        </div>
          <div  onClick={() => this.addActiveClass(2)}>
          <p>2</p>
        </div>
      </div>
    );
  }
}

Method overloading deals with the notion of having two or more methods in the same class with the same name but different arguments.

void foo(int a)
void foo(int a, float b)

Method overriding means having two methods with the same arguments, but different implementations. One of them would exist in the parent class, while another will be in the derived, or child class. The @Override annotation, while not required, can be helpful to enforce proper overriding of a method at compile time.

class Parent {
    void foo(double d) {
        // do something
    }
}

class Child extends Parent {

    @Override
    void foo(double d){
        // this method is overridden.  
    }
}

You can use date(t_stamp) to get only the date part from a timestamp.

You can check the date() function in the docs

DATE(expr)

Extracts the date part of the date or datetime expression expr.

mysql> SELECT DATE('2003-12-31 01:02:03'); -> '2003-12-31'

[root@pentest3r ~]# (find / -xdev -size +1024M) | (while read a ; do aa=$(du -sh $a | cut -d "." -f1 ); o=$(( $o+$aa )); done; echo "$o";)

1)event.stopPropagation(): =>It is used to stop executions of its corresponding parent handler only.

2) event.stopImmediatePropagation(): => It is used to stop the execution of its corresponding parent handler and also handler or function attached to itself except the current handler. => It also stops all the handler attached to the current element of entire DOM.

Here is the example: Jsfiddle!

What you've made is a dictionary and not a Set.

The update method in dictionary is used to update the new dictionary from a previous one, like so,

>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}

Whereas in sets, it is used to add elements to the set.

>>> D.update([1, 2])
>>> D
set([1, 2])

Damn Exceptions!

I love this answer. However, since next() raise a StopIteration exception when there are no items, i would use the following snippet to avoid an exception:

a = []
item = next((x for x in a), None)

For example,

a = []
item = next(x for x in a)

Will raise a StopIteration exception;

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
StopIteration

Assigning questionFrame.frame.size.height= screenSize.height * 0.30 will not reflect anything in the view. because it is a get-only property. If you want to change the frame of questionFrame you can use the below code.

questionFrame.frame = CGRect(x: 0, y: 0, width: 0, height: screenSize.height * 0.70)

I hope this help. Haven't tried it out yet, will post again once I tested it.

$blog is an object not an array

try using $blog->id instead of $blog['id']

Improving the amazing answer from @Brandon, I added type to ntext and xml using castings:

DECLARE @Results TABLE (ColumnName nvarchar(370), ColumnValue nvarchar(3630))

ROLLBACK

If you don't feel like dropping and recreating the whole shebang just to reload your data, you could use MyModel.destroy_all (or delete_all) in the seed.db file to clean out a table before your MyModel.create!(...) statements load the data. Then, you can redo the db:seed operation over and over. (Obviously, this only affects the tables you've loaded data into, not the rest of them.)

There's a "dirty hack" at https://stackoverflow.com/a/14957893/4553442 to add a "de-seeding" operation similar to migrating up and down...

All good answers, but I did not saw a reference to java.util.Collections which uses tons of static inner class for their static factor methods. So adding the same.

Adding an example from java.util.Collections which has multiple static inner class. Inner classes are useful to group code which needs to be accessed via outer class.

/**
 * @serial include
 */
static class UnmodifiableSet<E> extends UnmodifiableCollection<E>
                             implements Set<E>, Serializable {
    private static final long serialVersionUID = -9215047833775013803L;

    UnmodifiableSet(Set<? extends E> s)     {super(s);}
    public boolean equals(Object o) {return o == this || c.equals(o);}
    public int hashCode()           {return c.hashCode();}
}

Here is the static factor method in the java.util.Collections class

public static <T> Set<T> unmodifiableSet(Set<? extends T> s) {
    return new UnmodifiableSet<>(s);
}

If your code must run under Python2 and Python3, use the 2to3 six library like this:

import six

six.next(g)  # on PY2K: 'g.next()' and onPY3K: 'next(g)'

Remember that there is a difference between whether the query works and whether it works efficiently! A LINQ statement gets converted to T-SQL when the target of the statement is SQL Server, so you need to think about the T-SQL that would be produced.

Using String.Equals will most likely (I am guessing) bring back all of the rows from SQL Server and then do the comparison in .NET, because it is a .NET expression that cannot be translated into T-SQL.

In other words using an expression will increase your data access and remove your ability to make use of indexes. It will work on small tables and you won't notice the difference. On a large table it could perform very badly.

That's one of the problems that exists with LINQ; people no longer think about how the statements they write will be fulfilled.

In this case there isn't a way to do what you want without using an expression - not even in T-SQL. Therefore you may not be able to do this more efficiently. Even the T-SQL answer given above (using variables with collation) will most likely result in indexes being ignored, but if it is a big table then it is worth running the statement and looking at the execution plan to see if an index was used.

This is an informational message only. What the message is telling you is that the chromedriver executable will only accept connections from the local machine.

Most driver implementations (the Chrome driver and the IE driver for sure) create a HTTP server. The language bindings (Java, Python, Ruby, .NET, etc.) all use a JSON-over-HTTP protocol to communicate with the driver and automate the browser. Since the HTTP server is simply listening on an open port for HTTP requests generated by the language bindings, connections to the HTTP server started by the language bindings are only allowed to come from other processes on the same host. Note carefully that this limitation does not apply to connections the browser can make to outside websites; rather it simply prevents incoming connections from other websites.

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

Using Form Model (Reactive Forms)

--- Html code--
<form [formGroup]="patientCategory">
<mat-form-field class="full-width">
    <mat-select placeholder="Category" formControlName="patientCategory">
        <mat-option>--</mat-option>
        <mat-option *ngFor="let category of patientCategories" [value]="category">
            {{category.name}} 
        </mat-option>
    </mat-select>
</mat-form-field>

----ts code ---

ngOnInit() {

        this.patientCategory = this.fb.group({
            patientCategory: [null, Validators.required]
        });

      const toSelect = "Your Default Value";
      this.patientCategory.get('patientCategory').setValue(toSelect);
    }

With out form Model

--- html code --
<mat-form-field>
  <mat-label>Select an option</mat-label>
  <mat-select [(value)]="selected">
    <mat-option>None</mat-option>
    <mat-option value="option1">Option 1</mat-option>
    <mat-option value="option2">Option 2</mat-option>
    <mat-option value="option3">Option 3</mat-option>
  </mat-select>
</mat-form-field>

---- ts code -- selected = 'option1'; Here take care about type of the value assigning

Try to do port forwarding,

adb forward tcp:<PC port> tcp:<device port>.

like:

adb forward tcp:5555 tcp:5555.

sounds like 5555 port is captured so use other one. As I know 7612 is empty

[Edit]

C:\Users\m>adb forward tcp:7612 tcp:7612

C:\Users\m>adb tcpip 7612
restarting in TCP mode port: 7612

C:\Users\m>adb connect 192.168.1.12
connected to 192.168.1.12:7612

Be sure that you connect to the right IP address. (You can download Network Info 2 to check your IP)

Most straightforward:

byte[] c = new byte[a.length + b.length];
System.arraycopy(a, 0, c, 0, a.length);
System.arraycopy(b, 0, c, a.length, b.length);

Nevermind I found it. It can be done in the manifest file under application just set the android label. Was thrown off at first becasue it didn't change my shortcut of the application's name.

textBox1.Background = Brushes.Blue;
textBox1.Foreground = Brushes.Yellow;

WPF Foreground and Background is of type System.Windows.Media.Brush. You can set another color like this:

using System.Windows.Media;

textBox1.Background = Brushes.White;
textBox1.Background = new SolidColorBrush(Colors.White);
textBox1.Background = new SolidColorBrush(Color.FromArgb(0xFF, 0xFF, 0, 0));
textBox1.Background = System.Windows.SystemColors.MenuHighlightBrush;

You started with ManyToOne mapping , then you put OneToMany mapping as well for BiDirectional way. Then at OneToMany side (usually your parent table/class), you have to mention "mappedBy" (mapping is done by and in child table/class), so hibernate will not create EXTRA mapping table in DB (like TableName = parent_child).

The following should work, but you may need to change the format:

echo date('l F jS, Y (m-d-Y)', strtotime('+3 months', strtotime($DateToAdjust)));

My dad moved his office after 30 year and they need to update the address in the header of their Crystal Reports 7 (1997!) based billing system.

After buying old copies of Access 97 and Visual Studio 2003 Pro, I found out that both programs were too new - they could open the RPT files, but they saved them with an updated version that would not open in the billing system.

I ended up being able to make the changes using this life-saver program...

http://www.softwareforces.com/Products/rpt-inspector-professional-suite-for-crystal-reports

It was available with a 10 day free trial, and I only needed about 10 minutes to make my changes. That said, I would have happily paid whatever they asked for it. :)

Some hints:

1. When I opened my RPT files, I got an error saving the database could not be found. I ignored this error and everything worked fine.
2. Because my RPT files were Crystal Reports version 7, I had to go into Options->Misc and tell the program to save in the old format...

You are trying to assign to literal integer values. 1, 2, etc. are not valid names; they are only valid integers:

>>> 1
1
>>> 1 = 'something'
  File "<stdin>", line 1
SyntaxError: can't assign to literal

You probably want to use a list or dictionary instead:

names = []
for i in range(1, 6):
    name = input("Please enter name {}:".format(i))
    names.append(name)

Using a list makes it much easier to pick a random value too:

winner = random.choice(names)
print('Well done {}. You are the winner!'.format(winner))

If youR data was in A1:C100 then:

Excel - all versions

=SUMPRODUCT(--(A1:A100="M"),--(C1:C100="Yes"))

Excel - 2007 onwards

=COUNTIFS(A1:A100,"M",C1:C100,"Yes")

Try str_detect() from the stringr package, which detects the presence or absence of a pattern in a string.

Here is an approach that also incorporates the %>% pipe and filter() from the dplyr package:

library(stringr)
library(dplyr)

CO2 %>%
  filter(str_detect(Treatment, "non"))

   Plant        Type  Treatment conc uptake
1    Qn1      Quebec nonchilled   95   16.0
2    Qn1      Quebec nonchilled  175   30.4
3    Qn1      Quebec nonchilled  250   34.8
4    Qn1      Quebec nonchilled  350   37.2
5    Qn1      Quebec nonchilled  500   35.3
...

This filters the sample CO2 data set (that comes with R) for rows where the Treatment variable contains the substring "non". You can adjust whether str_detect finds fixed matches or uses a regex - see the documentation for the stringr package.

Use an interface to show it who's boss.

public interface SleskeEnum {
    int id();

    SleskeEnum[] getValues();

}

public enum BonusType implements SleskeEnum {


  MONTHLY(1), YEARLY(2), ONE_OFF(3);

  public final int id;

  BonusType(int id) {
    this.id = id;
  }

  public SleskeEnum[] getValues() {
    return values();
  }

  public int id() { return id; }


}

public class Utils {

  public static SleskeEnum getById(SleskeEnum type, int id) {
      for(SleskeEnum t : type.getValues())
          if(t.id() == id) return t;
      throw new IllegalArgumentException("BonusType does not accept id " + id);
  }

  public static void main(String[] args) {

      BonusType shouldBeMonthly = (BonusType)getById(BonusType.MONTHLY,1);
      System.out.println(shouldBeMonthly == BonusType.MONTHLY);

      BonusType shouldBeMonthly2 = (BonusType)getById(BonusType.MONTHLY,1);
      System.out.println(shouldBeMonthly2 == BonusType.YEARLY);

      BonusType shouldBeYearly = (BonusType)getById(BonusType.MONTHLY,2);
      System.out.println(shouldBeYearly  == BonusType.YEARLY);

      BonusType shouldBeOneOff = (BonusType)getById(BonusType.MONTHLY,3);
      System.out.println(shouldBeOneOff == BonusType.ONE_OFF);

      BonusType shouldException = (BonusType)getById(BonusType.MONTHLY,4);
  }
}

And the result:

C:\Documents and Settings\user\My Documents>java Utils
true
false
true
true
Exception in thread "main" java.lang.IllegalArgumentException: BonusType does not accept id 4
        at Utils.getById(Utils.java:6)
        at Utils.main(Utils.java:23)

C:\Documents and Settings\user\My Documents>

How about something like:

gem dependency devise --pipe | cut -d \  -f 1 | xargs gem uninstall -a

(this assumes that you're not using bundler - but I guess you're not since removing from your bundle gemspec would solve the problem)

Dynamic analysis methods

Here I describe a few dynamic analysis methods.

Dynamic methods actually run the program to determine the call graph.

The opposite of dynamic methods are static methods, which try to determine it from the source alone without running the program.

Advantages of dynamic methods:

• catches function pointers and virtual C++ calls. These are present in large numbers in any non-trivial software.

Disadvantages of dynamic methods:

• you have to run the program, which might be slow, or require a setup that you don't have, e.g. cross-compilation
• only functions that were actually called will show. E.g., some functions could be called or not depending on the command line arguments.

KcacheGrind

https://kcachegrind.github.io/html/Home.html

Test program:

int f2(int i) { return i + 2; }
int f1(int i) { return f2(2) + i + 1; }
int f0(int i) { return f1(1) + f2(2); }
int pointed(int i) { return i; }
int not_called(int i) { return 0; }

int main(int argc, char **argv) {
    int (*f)(int);
    f0(1);
    f1(1);
    f = pointed;
    if (argc == 1)
        f(1);
    if (argc == 2)
        not_called(1);
    return 0;
}

Usage:

sudo apt-get install -y kcachegrind valgrind

# Compile the program as usual, no special flags.
gcc -ggdb3 -O0 -o main -std=c99 main.c

# Generate a callgrind.out.<PID> file.
valgrind --tool=callgrind ./main

# Open a GUI tool to visualize callgrind data.
kcachegrind callgrind.out.1234

You are now left inside an awesome GUI program that contains a lot of interesting performance data.

On the bottom right, select the "Call graph" tab. This shows an interactive call graph that correlates to performance metrics in other windows as you click the functions.

To export the graph, right click it and select "Export Graph". The exported PNG looks like this:

From that we can see that:

• the root node is _start, which is the actual ELF entry point, and contains glibc initialization boilerplate
• f0, f1 and f2 are called as expected from one another
• pointed is also shown, even though we called it with a function pointer. It might not have been called if we had passed a command line argument.
• not_called is not shown because it didn't get called in the run, because we didn't pass an extra command line argument.

The cool thing about valgrind is that it does not require any special compilation options.

Therefore, you could use it even if you don't have the source code, only the executable.

valgrind manages to do that by running your code through a lightweight "virtual machine". This also makes execution extremely slow compared to native execution.

As can be seen on the graph, timing information about each function call is also obtained, and this can be used to profile the program, which is likely the original use case of this setup, not just to see call graphs: How can I profile C++ code running on Linux?

Tested on Ubuntu 18.04.

gcc -finstrument-functions + etrace

https://github.com/elcritch/etrace

-finstrument-functions adds callbacks, etrace parses the ELF file and implements all callbacks.

I couldn't get it working however unfortunately: Why doesn't `-finstrument-functions` work for me?

Claimed output is of format:

\-- main
|   \-- Crumble_make_apple_crumble
|   |   \-- Crumble_buy_stuff
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   |   \-- Crumble_buy
|   |   \-- Crumble_prepare_apples
|   |   |   \-- Crumble_skin_and_dice
|   |   \-- Crumble_mix
|   |   \-- Crumble_finalize
|   |   |   \-- Crumble_put
|   |   |   \-- Crumble_put
|   |   \-- Crumble_cook
|   |   |   \-- Crumble_put
|   |   |   \-- Crumble_bake

Likely the most efficient method besides specific hardware tracing support, but has the downside that you have to recompile the code.

No. We cannot alter the constraint, only thing we can do is drop and recreate it

ALTER TABLE [TABLENAME] DROP CONSTRAINT [CONSTRAINTNAME]

Foreign Key Constraint

Alter Table Table1 Add Constraint [CONSTRAINTNAME] Foreign Key (Column) References Table2 (Column) On Update Cascade On Delete Cascade

Primary Key constraint

Alter Table Table add constraint [Primary Key] Primary key(Column1,Column2,.....)

You could use an anonymous function:

var counter = 10;
var myFunction = function(){
    clearInterval(interval);
    counter *= 10;
    interval = setInterval(myFunction, counter);
}
var interval = setInterval(myFunction, counter);

UPDATE: As suggested by A. Wolff, use setTimeout to avoid the need for clearInterval.

var counter = 10;
var myFunction = function() {
    counter *= 10;
    setTimeout(myFunction, counter);
}
setTimeout(myFunction, counter);

Update for Font Awesome 5 using SCSS

.icon {
  @extend %fa-icon;
  @extend .fas;

  &:before {
    content: fa-content($fa-var-user);
  }
}

You can simply return if you want to skip the current iteration.

Since you're in a function, if you return before doing anything else, then you have effectively skipped execution of the code below the return statement.

The simplest way is to use the: NSSM - the Non-Sucking Service Manager. Just download and unzip to a location of your choosing. It's a self-contained utility, around 300KB (much less than installing the entire pywin32 suite just for this purpose) and no "installation" is needed. The zip contains a 64-bit and a 32-bit version of the utility. Either should work well on current systems (you can use the 32-bit version to manage services on 64-bit systems).

GUI approach

1 - install the python program as a service. Open a Win prompt as admin

c:\>nssm.exe install WinService

2 - On NSSM´s GUI console:

path: C:\Python27\Python27.exe

Startup directory: C:\Python27

Arguments: c:\WinService.py

3 - check the created services on services.msc

Scripting approach (no GUI)

This is handy if your service should be part of an automated, non-interactive procedure, that may be beyond your control, such as a batch or installer script. It is assumed that the commands are executed with administrative privileges.

For convenience the commands are described here by simply referring to the utility as nssm.exe. It is advisable, however, to refer to it more explicitly in scripting with its full path c:\path\to\nssm.exe, since it's a self-contained executable that may be located in a private path that the system is not aware of.

1. Install the service

You must specify a name for the service, the path to the proper Python executable, and the path to the script:

nssm.exe install ProjectService "c:\path\to\python.exe" "c:\path\to\project\app\main.py"

More explicitly:

nssm.exe install ProjectService 
nssm.exe set ProjectService Application "c:\path\to\python.exe"
nssm.exe set ProjectService AppParameters "c:\path\to\project\app\main.py"

Alternatively you may want your Python app to be started as a Python module. One easy approach is to tell nssm that it needs to change to the proper starting directory, as you would do yourself when launching from a command shell:

nssm.exe install ProjectService "c:\path\to\python.exe" "-m app.main"
nssm.exe set ProjectService AppDirectory "c:\path\to\project"

This approach works well with virtual environments and self-contained (embedded) Python installs. Just make sure to have properly resolved any path issues in those environments with the usual methods. nssm has a way to set environment variables (e.g. PYTHONPATH) if needed, and can also launch batch scripts.

2. To start the service

nssm.exe start ProjectService 

3. To stop the service

nssm.exe stop ProjectService

4. To remove the service, specify the confirm parameter to skip the interactive confirmation.

nssm.exe remove ProjectService confirm

I also had a similar problem

My problem was solved by doing the following:

This is an interesting question, and I started thinking about how I would implement something like this.

I came up with this (fiddle);

Basically, instead of trying to call a directive from a controller, I created a module to house all the popdown logic:

var PopdownModule = angular.module('Popdown', []);

I put two things in the module, a factory for the API which can be injected anywhere, and the directive for defining the behavior of the actual popdown element:

The factory just defines a couple of functions success and error and keeps track of a couple of variables:

PopdownModule.factory('PopdownAPI', function() {
    return {
        status: null,
        message: null,
        success: function(msg) {
            this.status = 'success';
            this.message = msg;
        },
        error: function(msg) {
            this.status = 'error';
            this.message = msg;
        },
        clear: function() {
            this.status = null;
            this.message = null;
        }
    }
});

The directive gets the API injected into its controller, and watches the api for changes (I'm using bootstrap css for convenience):

PopdownModule.directive('popdown', function() {
    return {
        restrict: 'E',
        scope: {},
        replace: true,
        controller: function($scope, PopdownAPI) {
            $scope.show = false;
            $scope.api = PopdownAPI;

            $scope.$watch('api.status', toggledisplay)
            $scope.$watch('api.message', toggledisplay)

            $scope.hide = function() {
                $scope.show = false;
                $scope.api.clear();
            };

            function toggledisplay() {
                $scope.show = !!($scope.api.status && $scope.api.message);               
            }
        },
        template: '<div class="alert alert-{{api.status}}" ng-show="show">' +
                  '  <button type="button" class="close" ng-click="hide()">&times;</button>' +
                  '  {{api.message}}' +
                  '</div>'
    }
})

Then I define an app module that depends on Popdown:

var app = angular.module('app', ['Popdown']);

app.controller('main', function($scope, PopdownAPI) {
    $scope.success = function(msg) { PopdownAPI.success(msg); }
    $scope.error   = function(msg) { PopdownAPI.error(msg); }
});

And the HTML looks like:

<html ng-app="app">
    <body ng-controller="main">
        <popdown></popdown>
        <a class="btn" ng-click="success('I am a success!')">Succeed</a>
        <a class="btn" ng-click="error('Alas, I am a failure!')">Fail</a>
    </body>
</html>

I'm not sure if it's completely ideal, but it seemed like a reasonable way to set up communication with a global-ish popdown directive.

Again, for reference, the fiddle.

Yes, there is a command to find the size of a database in Postgres. It's the following:

SELECT pg_database.datname as "database_name", pg_size_pretty(pg_database_size(pg_database.datname)) AS size_in_mb FROM pg_database ORDER by size_in_mb DESC;

If memory serves correct, the reg add command will NOT create the entire directory path if it does not exist. Meaning that if any of the parent registry keys do not exist then they must be created manually one by one. It is really annoying, I know! Example:

@echo off
reg add "HKCU\Software\Policies"
reg add "HKCU\Software\Policies\Microsoft"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel"
reg add "HKCU\Software\Policies\Microsoft\Internet Explorer\Control Panel" /v HomePage /t REG_DWORD /d 1 /f

This is now trivial in tidyr with replace_na(). The function appears to work for data.tables as well as data.frames:

tidyr::replace_na(x, list(a=0, b=0))

I used AtomicInteger to solve the Dining Philosopher's problem.

In my solution, AtomicInteger instances were used to represent the forks, there are two needed per philosopher. Each Philosopher is identified as an integer, 1 through 5. When a fork is used by a philosopher, the AtomicInteger holds the value of the philosopher, 1 through 5, otherwise the fork is not being used so the value of the AtomicInteger is -1.

The AtomicInteger then allows to check if a fork is free, value==-1, and set it to the owner of the fork if free, in one atomic operation. See code below.

AtomicInteger fork0 = neededForks[0];//neededForks is an array that holds the forks needed per Philosopher
AtomicInteger fork1 = neededForks[1];
while(true){    
    if (Hungry) {
        //if fork is free (==-1) then grab it by denoting who took it
        if (!fork0.compareAndSet(-1, p) || !fork1.compareAndSet(-1, p)) {
          //at least one fork was not succesfully grabbed, release both and try again later
            fork0.compareAndSet(p, -1);
            fork1.compareAndSet(p, -1);
            try {
                synchronized (lock) {//sleep and get notified later when a philosopher puts down one fork                    
                    lock.wait();//try again later, goes back up the loop
                }
            } catch (InterruptedException e) {}

        } else {
            //sucessfully grabbed both forks
            transition(fork_l_free_and_fork_r_free);
        }
    }
}

Because the compareAndSet method does not block, it should increase throughput, more work done. As you may know, the Dining Philosophers problem is used when controlled accessed to resources is needed, i.e. forks, are needed, like a process needs resources to continue doing work.

I would like to share more about the usage of the scroll text fragment

syntax: #:~:text=[prefix-,]textStart[,textEnd][,-suffix]

If you want to highlight multiple text fragments in one URL (&text=)

see more: https://web.dev/text-fragments/#textstart

You can try this modal:https://github.com/xue2han/react-dynamic-modal It is stateless and can be rendered only when needed.So it is very easy to use.Just like this:

    class MyModal extends Component{
       render(){
          const { text } = this.props;
          return (
             <Modal
                onRequestClose={this.props.onRequestClose}
                openTimeoutMS={150}
                closeTimeoutMS={150}
                style={customStyle}>
                <h1>What you input : {text}</h1>
                <button onClick={ModalManager.close}>Close Modal</button>
             </Modal>
          );
       }
    }

    class App extends Component{
        openModal(){
           const text = this.refs.input.value;
           ModalManager.open(<MyModal text={text} onRequestClose={() => true}/>);
        }
        render(){
           return (
              <div>
                <div><input type="text" placeholder="input something" ref="input" /></div>
                <div><button type="button" onClick={this.openModal.bind(this)}>Open Modal </button> </div>
              </div>
           );
        }
    }

    ReactDOM.render(<App />,document.getElementById('main'));

I was getting the same error when trying to run a publish process through powershell on my build machine.

My build machine only has the Windows SDK installed and not Visual Studio and as such it appears that I'm missing some common files and registry values that are normally present when Visual Studio is installed. After looking into vsvars32.bat a bit more carefully I noticed that it was where the "Cannot determine the location of the VS Common Tools folder" error was being reported located under the GetVSCommonToolsDir label. It appears that in this batch file that since the VS7 sub-key doesn't exist on my machine it blanks out the %VS100COMNTOOLS% environment variable and reports back the specified error.

In my case it appears that this error is happening for me because I don't have Visual Studio or some other necessary components installed on my build machine and thus the registry key doesn't exist. Perhaps your error is due to something similar such as 32-bit vs 64-bit registry or 32-bit vs 64-bit VS command prompt? Testing the line of code that is failing from the batch directly in the command prompt should give you a clue about why the registry or file path isn't being resolved properly.

The POST method should be sent along the HTTP request object. And the request may contain either of HTTP header or HTTP body or both.

Hence let's create an HTTP entity and send the headers and parameter in body.

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

MultiValueMap<String, String> map= new LinkedMultiValueMap<String, String>();
map.add("email", "[email protected]");

HttpEntity<MultiValueMap<String, String>> request = new HttpEntity<MultiValueMap<String, String>>(map, headers);

ResponseEntity<String> response = restTemplate.postForEntity( url, request , String.class );

In React Native , This worked for me

name = "hi \n\ruser"
name.replace( /[\r\n]+/gm, ""); // hi user

Following lines are used to define a font in css

@font-face {
    font-family: 'EntezareZohoor2';
    src: url('fonts/EntezareZohoor2.eot'), url('fonts/EntezareZohoor2.ttf') format('truetype'), url('fonts/EntezareZohoor2.svg') format('svg');
    font-weight: normal;
    font-style: normal;
}

Following lines to define/use the font in css

#newfont{
    font-family:'EntezareZohoor2';
}

Also, for simulating a slow connection on some *nixes, you can try using ipfw. More information is provided by Ben Newman's answer on this Quora question

Most of the suggestions are now, no longer valid.

The correct fix as of today, is to use the 'button' layout.

eg. <div class="fb-like" data-href="https://developers.facebook.com/docs/plugins/" data-layout="button" data-action="like" data-show-faces="true" data-share="false"></div>

The FB Docs, seem not to be fully updated yet... if you scroll down you'll see they state only 3 layouts are available, yet the dropdown suggests 4.

This means you can now use a less hacky solution!

I know this is a year old, but I just discovered this works perfectly for an EditText.

EditText textin = (EditText) findViewById(R.id.editText1);
textin.setInputType(InputType.TYPE_CLASS_TEXT);

It prevents anything but text and space. I could not tab, "return" ("\n"), or anything.

So, I had this recently also, for integrated security, It turns out that my issue was actually fairly simple to fix but mainly because I had forgotten to add "Trusted_Connection=True" to my connection string.

I know that may seem fairly obvious but it had me going for 20 minutes or so until I realised that I had copied my connection string format from connectionstrings.com and that portion of the connection string was missing.

Simple and I feel a bit daft, but it was the answer for me.

This can happen if you call

 .SingleOrDefault() 

on an IEnumerable with 2 or more elements.

You can experiment with the native DB driver for Excel in language/platform of your choice. In Java world, you can try with http://code.google.com/p/sqlsheet/ which provides a JDBC driver for working with Excel sheets directly. Similarly, you can get drivers for the DB technology for other platforms.

However, I can guarantee that you will soon hit a wall with the number of features these wrapper libraries provide. Better way will be to use Apache HSSF/POI or similar level of library but it will need more coding effort.

Install the latest version of TDM-GCC here is the link-http://wiki.codeblocks.org/index.php/MinGW_installation

EncodedParams variable is redefined as params variable will not work. You need to have same predefined call to variable, otherwise it looks possible with a little more work. Cheers! json is not used to its full capabilities in php there are better ways to call json which I don't recall at the moment.

I can't believe this is still an issue so long after it's been reported. The above solutions didn't work for me, as safari seemed to know when the element was not displayed or off-screen, however the following did work for me:

<div style="height:0px; overflow:hidden; ">
  Username <input type="text" name="fake_safari_username" >
  Password <input type="password" name="fake_safari_password">
</div>

Hope that's useful for somebody!

It is just a matter of using text indentation in the query editor.

Expanded View:

Collapsed View:

simply you can use

$("#yourtextboxid").attr("placeholder", "variable");

where, if variable is string then you can use like above, if it is variable replace it with the name like "variable" with out double quotes.

eg: $("#youtextboxid").attr("placeholder", variable); it will work.

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

I wrote this code some days back by recursion.

public static Map<String, Object> jsonToMap(JSONObject json) throws JSONException {
    Map<String, Object> retMap = new HashMap<String, Object>();

    if(json != JSONObject.NULL) {
        retMap = toMap(json);
    }
    return retMap;
}

public static Map<String, Object> toMap(JSONObject object) throws JSONException {
    Map<String, Object> map = new HashMap<String, Object>();

    Iterator<String> keysItr = object.keys();
    while(keysItr.hasNext()) {
        String key = keysItr.next();
        Object value = object.get(key);

        if(value instanceof JSONArray) {
            value = toList((JSONArray) value);
        }

        else if(value instanceof JSONObject) {
            value = toMap((JSONObject) value);
        }
        map.put(key, value);
    }
    return map;
}

public static List<Object> toList(JSONArray array) throws JSONException {
    List<Object> list = new ArrayList<Object>();
    for(int i = 0; i < array.length(); i++) {
        Object value = array.get(i);
        if(value instanceof JSONArray) {
            value = toList((JSONArray) value);
        }

        else if(value instanceof JSONObject) {
            value = toMap((JSONObject) value);
        }
        list.add(value);
    }
    return list;
}

You could just return an Object as all types are descended from Object.

public Object GetAnything()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();

     return radio; or return computer; or return hello //should be possible?!      
}

You could then cast to its relevant type:

Hello hello = (Hello)GetAnything();

If you didn't know what the type was going to be then you could use the is keyword.

Object obj = GetAnything();
if (obj is Hello) {
    // Do something
}

This being said I would be reluctant to write code like that. It would be much better to have an interface which is implemented by each of your classes.

public ISpeak GetAnything()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio();

     return radio; or return computer; or return hello //should be possible?!      
}

interface ISpeak 
{
   void Speak();
}

and have each of your classes implement the interface:

public class Hello : ISpeak
{
    void Speak() {
        Console.WriteLine("Hello");
    }
}

You could then do something like:

GetAnything().Speak();

For using FusedLocationProviderClient with Google Play Services 11 and higher:

see here: How to get current Location in GoogleMap using FusedLocationProviderClient

For using (now deprecated) FusedLocationProviderApi:

If your project uses Google Play Services 10 or lower, using the FusedLocationProviderApi is the optimal choice.

The FusedLocationProviderApi offers less battery drain than the old open source LocationManager API. Also, if you're already using Google Play Services for Google Maps, there's no reason not to use it.

Here is a full Activity class that places a Marker at the current location, and also moves the camera to the current position.

It also checks for the Location permission at runtime for Android 6 and later (Marshmallow, Nougat, Oreo). In order to properly handle the Location permission runtime check that is necessary on Android M/Android 6 and later, you need to ensure that the user has granted your app the Location permission before calling mGoogleMap.setMyLocationEnabled(true) and also before requesting location updates.

Show permission explanation if needed using an AlertDialog (this happens if the user denies a permission request, or grants the permission and then later revokes it in the settings):

Prompt the user for Location permission by calling ActivityCompat.requestPermissions():

Move camera to current location and place Marker when the Location permission is granted:

Use repr()[1:-1]. In this case, the double quotes don't need to be escaped. The [-1:1] slice is to remove the single quote from the beginning and the end.

>>> x = raw_input()
I'm "stuck" :\
>>> print x
I'm "stuck" :\
>>> print repr(x)[1:-1]
I\'m "stuck" :\\

Or maybe you just want to escape a phrase to paste into your program? If so, do this:

>>> raw_input()
I'm "stuck" :\
'I\'m "stuck" :\\'

I had the same challenge. This is the solution I found to add users to roles.

internal class Security
{
    ApplicationDbContext context = new ApplicationDbContext();

    internal void AddUserToRole(string userName, string roleName)
    {
        var UserManager = new UserManager<ApplicationUser>(new UserStore<ApplicationUser>(context));

        try
        {
            var user = UserManager.FindByName(userName);
            UserManager.AddToRole(user.Id, roleName);
            context.SaveChanges();
        }
        catch
        {
            throw;
        }
    }
}

Try this, Add @ob_start() function in top of the page,

if ((isset($_POST['cancel'])) && ($_POST['cancel'] == 'cancel'))
{
    header('Location: page1.php');
    exit();
}

It can be this:

The code you have posted here and code on your site both are different. There is a break <br> after second image, so the third image into new line, remove this <br> and it will display correctly.

I know, I am tooooo late to post an answer, but hoping that it might help someone. Plus, I just solved this issue I had with my tests. This is what I had in my test:

My test class

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "path-to-context" })
@Transactional
public class MyIntegrationTest 

Context xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
   <property name="driverClassName" value="${jdbc.driverClassName}" />
   <property name="url" value="${jdbc.url}" />
   <property name="username" value="${jdbc.username}" />
   <property name="password" value="${jdbc.password}" />
</bean>

I still had the problem that, the database was not being cleaned up automatically.

Issue was resolved when I added following property to BasicDataSource

<property name="defaultAutoCommit" value="false" />

Hope it helps.

You can use split() to get string array from comma separated string. If you iterate and perform mathematical operation on element of string array then that element will be treated as number by run-time cast but still you have string array. To convert comma separated string int array see the edit.

arr = strVale.split(',');

Live Demo

var strVale = "130,235,342,124";
arr = strVale.split(',');
for(i=0; i < arr.length; i++)
    console.log(arr[i] + " * 2 = " + (arr[i])*2);

Output

130 * 2 = 260
235 * 2 = 470
342 * 2 = 684
124 * 2 = 248

Edit, Comma separated string to int Array In the above example the string are casted to numbers in expression but to get the int array from string array you need to convert it to number.

var strVale = "130,235,342,124";
var strArr = strVale.split(',');
var intArr = [];
for(i=0; i < strArr.length; i++)
   intArr.push(parseInt(strArr[i]));

You will have the same object two times in your array, because object values are passed by reference. You have to create a new object like this

myElement.id = 244;
myElement.value = 3556;
myArray[0] = $.extend({}, myElement); //for shallow copy or
myArray[0] = $.extend(true, {}, myElement); // for deep copy

or

myArray.push({ id: 24, value: 246 });

If you like doing things the hard way:

my (undef,undef,undef,$mday,$mon,$year) = localtime;
$year = $year+1900;
$mon += 1;
if (length($mon)  == 1) {$mon = "0$mon";}
if (length($mday) == 1) {$mday = "0$mday";}
my $today = "$mon/$mday/$year";

In old version you can only use the ifequal or ifnotequal

{% ifequal YourVariable ExpectValue %}
    # Do something here.
{% endifequal %}

Example:

{% ifequal userid 1 %}
  Hello No.1
{% endifequal %}

{% ifnotequal username 'django' %}
  You are not django!
{% else %}
  Hi django!
{% endifnotequal %}

As in the if tag, an {% else %} clause is optional.

The arguments can be hard-coded strings, so the following is valid:

{% ifequal user.username "adrian" %} ... {% endifequal %} An alternative to the ifequal tag is to use the if tag and the == operator.

ifnotequal Just like ifequal, except it tests that the two arguments are not equal.

An alternative to the ifnotequal tag is to use the if tag and the != operator.

However, now we can use if/else easily

{% if somevar >= 1 %}
{% endif %}

{% if "bc" in "abcdef" %}
  This appears since "bc" is a substring of "abcdef"
{% endif %}

Complex expressions

All of the above can be combined to form complex expressions. For such expressions, it can be important to know how the operators are grouped when the expression is evaluated - that is, the precedence rules. The precedence of the operators, from lowest to highest, is as follows:

• or
• and
• not
• in
• ==, !=, <, >, <=, >=

I think the easiest way to think about this variable like input parameter in lambda expression in C#. I.e. $_ is similar to x in x => Console.WriteLine(x) anonymous function in C#. Consider following examples:

PowerShell:

1,2,3 | ForEach-Object {Write-Host $_}

Prints:

1
2
3

or

1,2,3 | Where-Object {$_ -gt 1}

Prints:

2
3

And compare this with C# syntax using LINQ:

var list = new List<int> { 1, 2, 3 };
list.ForEach( _ => Console.WriteLine( _ ));

Prints:

1
2
3

or

list.Where( _ => _ > 1)
    .ToList()
    .ForEach(s => Console.WriteLine(s));

Prints:

2
3

The copy() runs for the least length of dst and src, so you must initialize the dst to the desired length.

A := []int{1, 2, 3}
B := make([]int, 3)
copy(B, A)
C := make([]int, 2)
copy(C, A)
fmt.Println(A, B, C)

Output:

[1 2 3] [1 2 3] [1 2]

You can initialize and copy all elements in one line using append() to a nil slice.

x := append([]T{}, []...)

Example:

A := []int{1, 2, 3}
B := append([]int{}, A...)
C := append([]int{}, A[:2]...)
fmt.Println(A, B, C)    

Output:

[1 2 3] [1 2 3] [1 2]

Comparing with allocation+copy(), for greater than 1,000 elements, use append. Actually bellow 1,000 the difference may be neglected, make it a go for rule of thumb unless you have many slices.

In your Project Directory there is a folder called "android" and inside it there is the local.properties file . Delete the file and the build should run successfully

You are modifying the list book_shop.values()[i], which is not getting updated in the dictionary. Whenever you call the values() method, it will give you the values available in dictionary, and here you are not modifying the data of the dictionary.

to get the WSDL (Web Service Description Language) from a Web Service URL.

Is possible from SOAP Web Services:

to get the WSDL we have only to add ?WSDL , for example:

Usually you can use the .animate() method to manipulate arbitrary CSS properties, but for background colors you need to use the color plugin. Once you include this plugin, you can use something like others have indicated $('div').animate({backgroundColor: '#f00'}) to change the color.

As others have written, some of this can be done using the jQuery UI library as well.

I have found a way to use JSONP method in $http directly and with support of params in the config object:

params = {
  'a': b,
  'callback': 'JSON_CALLBACK'
};

$http({
  url: url,
  method: 'JSONP',
  params: params
})

After struggling a lot while creating a low level utility to handle the post and get requests for my project, I decided to post my effort here. Much on the lines of accepted answer, here is a snippet for making http and https POST requests for sending JSON data.

const http = require("http")
const https = require("https")

// Request handler function
let postJSON = (options, postData, callback) => {

    // Serializing JSON
    post_data = JSON.stringify(postData)

    let port = options.port == 443 ? https : http

    // Callback function for the request
    let req = port.request(options, (res) => {
        let output = ''
        res.setEncoding('utf8')

        // Listener to receive data
        res.on('data', (chunk) => {
            output += chunk
        });

        // Listener for intializing callback after receiving complete response
        res.on('end', () => {
            let obj = JSON.parse(output)
            callback(res.statusCode, obj)
        });
    });

   // Handle any errors occurred while making request
    req.on('error', (err) => {
        //res.send('error: ' + err.message)
    });

    // Request is made here, with data as string or buffer
    req.write(post_data)
    // Ending the request
    req.end()
};

let callPost = () => {

    let data = {
        'name': 'Jon',
        'message': 'hello, world'
    }

    let options = {
        host: 'domain.name',       // Your domain name
        port: 443,                 // 443 for https and 80 for http
        path: '/path/to/resource', // Path for the request
        method: 'POST',            
        headers: {
            'Content-Type': 'application/json',
            'Content-Length': Buffer.byteLength(data)
        }
    }

    postJSON(options, data, (statusCode, result) => {
        // Handle response
        // Process the received data
    });

}

Best thing I came up without Java 8 was:

public static <T> T[] toArray(List<T> list, Class<T> objectClass) {
    if (list == null) {
        return null;
    }

    T[] listAsArray = (T[]) Array.newInstance(objectClass, list.size());
    list.toArray(listAsArray);
    return listAsArray;
}

If anyone has a better way to do this, please share :)

Are you familiar with numpy.nan?

You can create your own method such as:

def nans(shape, dtype=float):
    a = numpy.empty(shape, dtype)
    a.fill(numpy.nan)
    return a

Then

nans([3,4])

would output

array([[ NaN,  NaN,  NaN,  NaN],
       [ NaN,  NaN,  NaN,  NaN],
       [ NaN,  NaN,  NaN,  NaN]])

I found this code in a mailing list thread.

In my case, I try to add sudo

sudo nginx -v

Go to conversation tab then come down there is one "close pull request" button is there use that button to close pull request, Take ref of attached image

This seems to be the cleanest way to do

if (foo === 1) {

} else if (bar === 99) {

} else if (foo === 2) {

} else {

}

in the template:

<ng-container *ngIf="foo === 1; else elseif1">foo === 1</ng-container>
<ng-template #elseif1>
    <ng-container *ngIf="bar === 99; else elseif2">bar === 99</ng-container>
</ng-template>
<ng-template #elseif2>
    <ng-container *ngIf="foo === 2; else else1">foo === 2</ng-container>
</ng-template>
<ng-template #else1>else</ng-template>

Notice that it works like a proper else if statement should when the conditions involve different variables (only 1 case is true at a time). Some of the other answers don't work right in such a case.

aside: gosh angular, that's some really ugly else if template code...

The above claim that "If you are planning to draw a lot of pixel, it's a lot more efficient to use the image data of the canvas to do pixel drawing" seems to be quite wrong - at least with Chrome 31.0.1650.57 m or depending on your definition of "lot of pixel". I would have preferred to comment directly to the respective post - but unfortunately I don't have enough stackoverflow points yet:

I think that I am drawing "a lot of pixels" and therefore I first followed the respective advice for good measure I later changed my implementation to a simple ctx.fillRect(..) for each drawn point, see http://www.wothke.ch/webgl_orbittrap/Orbittrap.htm

Interestingly it turns out the silly ctx.fillRect() implementation in my example is actually at least twice as fast as the ImageData based double buffering approach.

At least for my scenario it seems that the built-in ctx.getImageData/ctx.putImageData is in fact unbelievably SLOW. (It would be interesting to know the percentage of pixels that need to be touched before an ImageData based approach might take the lead..)

Conclusion: If you need to optimize performance you have to profile YOUR code and act on YOUR findings..

Well, for me this is the expected result; adding six months to Jan. 1st July.

When calling java use the -Xmx Flag for example -Xmx512m for 512 megs for the heap size. You may also want to consider the -xms flag to start the heap larger if you are going to have it grow right from the start. The default size is 128megs.

You would use

/[a-z]/gi

[]--checks for any characters between given inputs

a-z---covers the entire alphabet

g-----globally throughout the whole string

i-----getting upper and lowercase

The recommended way, by Httpcomponents 4.1, is to close connection and release any underlying resources:

EntityUtils.consume(HttpEntity)

where HttpEntity passed is a response entity.

To simulate a dropped connection try

connection.destroy();

There's always the hardware route. Purchase two USB to serial converters, and connect them via a NULL modem.

Pro tips: 1) Windows may assign new COM ports to the adapters after every device sleep or reboot. 2) The market leaders in chips for USB to serial are Prolific and FTDI. Both companies are battling knockoffs, and may be blocked in future official Windows drivers. The Linux drivers however work fine with the clones.

How about this solution:

str="Hello World" (as stated in problem) srr = str+ ""

A roll your own function.

Supports recursion or not with the 2nd switch.

Also, allow names of files with ; which the accepted answer fails to address although a great answer, this will get over that issue.

The idea was taken from https://ss64.com/nt/empty.html

I realise that this article may be outdated but still I would like to ask smithsv to correct his source code, it contains many mistakes, I managed to correct most of them but still don't know what kind of object x509 could be.Here is the source code as I think is should be:

        KeyStore ks = KeyStore.getInstance( "pkcs12" );
        ks.load( new FileInputStream( cert.pfx ), "passwrd".toCharArray() );

        KeyStore jks = KeyStore.getInstance( "JKS" );
        jks.load( null );

        for( Enumeration t = ks.aliases(); t.hasMoreElements(); ) {
            String alias = (String )t.nextElement();
            System.out.println( "@:" + alias );
            if( ks.isKeyEntry( alias ) ) {
                Certificate[] a = ks.getCertificateChain( alias );
                for( int i = 0; i == 0; )
                    jks.setCertificateEntry( x509Cert.getSubjectDN().toString(), x509 );

                System.out.println( "ok" );
            }
        }

For this particular question, the standard suggestion of java.text.SimpleDateFormat works, but has the unfortunate side effect that SimpleDateFormat is not thread-safe and can be the source of particularly nasty problems since it'll corrupt your output in multi-threaded scenarios, and you won't get any exceptions!

I would strongly recommend looking at Joda for anything like this. Why ? It's a much richer and more intuitive time/date library for Java than the current library (and the basis of the up-and-coming new standard Java date/time library, so you'll be learning a soon-to-be-standard API).

If you're open to using jquery, you can set conditional statements using javascript within the html:

$('.class').css("color",((Variable > 0) ? "#009933":"#000"));

This will change the text color of .class to green if the value of Variable is greater than 0.

Don't really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don't need to hold all the data in memory at once (This can be faster or slower depending on the library/use case)

In shell:

1. Find supported UTF-8 locale by the following command:

   locale -a | grep "UTF-8"
   

2. Export it, before running the script, e.g.:

   export LC_ALL=$(locale -a | grep UTF-8)
   

   or manually like:

   export LC_ALL=C.UTF-8
   

3. Test it by printing special character, e.g. ™:

   python -c 'print(u"\u2122");'
   

Above tested in Ubuntu.

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

The target you tried to add in InputProps is not the same target you wanted which is in React.FormEvent

So, the solution I could come up with was, extending the event related types to add your target type, as:

interface MyEventTarget extends EventTarget {
    value: string
}

interface MyFormEvent<T> extends React.FormEvent<T> {
    target: MyEventTarget
}

interface InputProps extends React.HTMLProps<Input> {
    onChange?: React.EventHandler<MyFormEvent<Input>>;
}

Once you have those classes, you can use your input component as

<Input onChange={e => alert(e.target.value)} />

without compile errors. In fact, you can also use the first two interfaces above for your other components.

First (or in your .vimrc):

:set hlsearch

Then position your cursor over the word you want highlighted, and hit *.

hlsearch means highlight all occurrences of the current search, and * means search for the word under the cursor.

Visual Studio Code shows a link at the top of a Go test file which lets you run all the tests in just that file.

In the "Output" window, you can see that it automatically generates a regex which contains all of the test names in the current file:

Running tool: C:\Go\bin\go.exe test -timeout 30s -run ^(TestFoo|TestBar|TestBaz)$ rootpackage\mypackage

Note: the very first time you open a Go file in VS Code it automatically offers to install some Go extensions for you. I assume the above requires that you have previously accepted the offer to install.

We can cast an int to a double but we can't do the same with the wrapper classes Integer and Double:

 int     a = 1;
 Integer b = 1;   // inboxing, requires Java 1.5+

 double  c = (double) a;   // OK
 Double  d = (Double) b;   // No way.

This shows the compile time error that corresponds to your runtime exception.

CONVERT takes the column name, not a string containing the column name; your current expression tries to convert the string A.my_NvarcharColumn to an integer instead of the column content.

SELECT convert (int, N'A.my_NvarcharColumn') FROM A;

should instead be

SELECT convert (int, A.my_NvarcharColumn) FROM A;

Simple SQLfiddle here.

Run these commands in the terminal:

sudo apt-get remove --purge mysql-server mysql-client mysql-common

sudo apt-get autoremove

sudo apt-get autoclean

Run these commands separately as each command requires confirmation & if run as a block, the command below the one currently running will cancel the confirmation (leading to the command not being run).

There is an extension for that, but I have no usage experience yet:

The Uri class implements Parcelable, so you can add and extract it directly from the Intent

// Add a Uri instance to an Intent
intent.putExtra("imageUri", uri);

// Get a Uri from an Intent
Uri uri = intent.getParcelableExtra("imageUri");

You can use the same method for any objects that implement Parcelable, and you can implement Parcelable on your own objects if required.

It happen that after some time we need to run

 'php artisan passport:install --force 

again to generate a key this solved my problem ,

You can comment section of a script using a conditional.

For example, the following script:

DEBUG=false
if ${DEBUG}; then
echo 1
echo 2
echo 3
echo 4
echo 5
fi
echo 6
echo 7

would output:

6
7

In order to uncomment the section of the code, you simply need to comment the variable:

#DEBUG=false

(Doing so would print the numbers 1 through 7.)

I solved my problem using

git checkout -m old
git checkout -b new B
git merge -s ours old

I adopted the @Jotne solution and works perfectly! For example for mongodb server in my NAS

#! /bin/bash

case "$(pidof mongod | wc -w)" in

0)  echo "Restarting mongod:"
    mongod --config mongodb.conf
    ;;
1)  echo "mongod already running"
    ;;
esac

1. @QueryParam can be conveniently used with the Default Value annotation so that you can avoid a null pointer exception if no query parameter is passed.

When you want to parse query parameters from a GET request, you can simply define respective parameter to the method that will handle the GET request and annotate them with @QueryParam annotation

2. @PathParam extracts the URI values and matches to @Path. And hence gets the input parameter. 2.1 @PathParam can be more than one and is set to methods arguments

   @Path("/rest")
   public class Abc {
   
       @GET
       @Path("/msg/{p0}/{p1}")
       @Produces("text/plain")
       public String add(@PathParam("p0") Integer param1, @PathParam("p1")  Integer param2 )
       {
           return String.valueOf(param1+param2);
       }
   } 
   

In the above example,
http://localhost:8080/Restr/rest/msg/{p0}/{p1},
p0 matches param1 and p1 matches param2. So for the URI
http://localhost:8080/Restr/rest/msg/4/6,
we get the result 10.

In REST Service, JAX-RS provides @QueryParam and @FormParam both for accepting data from HTTP request. An HTTP form can be submitted by different methods like GET and POST.

@QueryParam : Accepts GET request and reads data from query string.

@FormParam: Accepts POST request and fetches data from HTML form or any request of the media

In continuation matts answer. we need to use https://math.stackexchange.com/questions/190111/how-to-check-if-a-point-is-inside-a-rectangle/190373#190373 solution to make it work

Below does not work
0 <= dot(AB,AM) <= dot(AB,AB) && 0 <= dot(BC,BM) <= dot(BC,BC)

Below works

From here:

// Add jQuery 
var GM_JQ = document.createElement('script'); 
GM_JQ.src = 'http://jquery.com/src/jquery-latest.js';
GM_JQ.type = 'text/javascript'; 
document.getElementsByTagName('head')[0].appendChild(GM_JQ); 

// Check if jQuery's loaded 
function GM_wait() 
{ 
    if(typeof unsafeWindow.jQuery == 'undefined') 
    { 
        window.setTimeout(GM_wait,100); 
    } 
    else 
    { 
        $ = unsafeWindow.jQuery; 
        letsJQuery(); 
    } 
} 

GM_wait(); 

// All your GM code must be inside this function 
function letsJQuery() 
{
    // Do your jQuery stuff in here    
} 

This will wait until jQuery is loaded to use it, but you can use the same concept, setting variables in your other scripts (or checking them if they're not your script) to wait until they're loaded to use them.

For example, on my site, I use this for asynchronous JS loading and waiting until they're finished before doing anything with them using jQuery:

<script type="text/javascript" language="JavaScript"> 
    function js(url){
        s = document.createElement("script");
        s.type = "text/javascript";
        s.src = url;
        document.getElementsByTagName("head")[0].appendChild(s);
    }       

    js("/js/jquery-ui.js");
    js("/js/jrails.js");
    js("/js/jquery.jgrowl-min.js");
    js("/js/jquery.scrollTo-min.js");
    js("/js/jquery.corner-min.js");
    js("/js/jquery.cookie-min.js");
    js("/js/application-min.js");

    function JS_wait() {
        if (typeof $.cookie == 'undefined' || // set in jquery.cookie-min.js
            typeof getLastViewedAnchor == 'undefined' || // set in application-min.js
            typeof getLastViewedArchive == 'undefined' || // set in application-min.js 
            typeof getAntiSpamValue == 'undefined') // set in application-min.js
        { 
            window.setTimeout(JS_wait, 100); 
        }
        else 
        { 
            JS_ready(); 
        }
    }

    function JS_ready() {
        // snipped
    };

    $(document).ready(JS_wait);
</script> 

To keep it basic, I used a loop and something like this to get you started (my index are datetimes):

import pandas as pd
import datetime as dt

#populate your dataframe: "df"
#...

df[df.index<(df.index[0]+dt.timedelta(hours=1))] #gives you a slice. you can then take .sum() .mean(), whatever

and then you can run functions on that slice. You can see how adding an iterator to make the start of the window something other than the first value in your dataframes index would then roll the window (you could use a > rule for the start as well for example).

Note, this may be less efficient for SUPER large data or very small increments as your slicing may become more strenuous (works for me well enough for hundreds of thousands of rows of data and several columns though for hourly windows across a few weeks)

Just as an addition to the other answers, here is the razor engine syntax:

<input type="button" value="Some text" onclick="@("window.location.href='" + @Url.Action("actionName", "controllerName") + "'");" />

or

window.location.href = '@Url.Action("actionName", "controllerName")';

var input = document.createElement("input");

input.setAttribute("type", "hidden");

input.setAttribute("name", "name_you_want");

input.setAttribute("value", "value_you_want");

//append to form element that you want .
document.getElementById("chells").appendChild(input);

I have just written an app which can make a call from a web page - I don't know if this is any use to you, but I include anyway:

in your onCreate you'll need to use a webview and assign a WebViewClient, as below:

browser = (WebView) findViewById(R.id.webkit);
browser.setWebViewClient(new InternalWebViewClient());

then handle the click on a phone number like this:

private class InternalWebViewClient extends WebViewClient {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
         if (url.indexOf("tel:") > -1) {
            startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
            return true;
        } else {
            return false;
        }
    }
}

Let me know if you need more pointers.

Have you tried os.mkdir?

You might also try this little code snippet:

mypath = ...
if not os.path.isdir(mypath):
   os.makedirs(mypath)

makedirs creates multiple levels of directories, if needed.

Let's try.. It is working for me..

You want awk.

This would be a quick and dirty hack:

awk -F "\"" '{print $2}' /tmp/file.txt

PortMappingEnabled
PortMappingLeaseDuration
RemoteHost
ExternalPort
ExternalPortEndRange
InternalPort
PortMappingProtocol
InternalClient
PortMappingDescription

This would be another option:

$('.id_100 option[value=val2]').prop('selected', true);

You can add this to your _Layout.cshtml:

@using MyProj.ViewModels;
...
    @if (TempData["UserMessage"] != null)
    {
        var message = (MessageViewModel)TempData["UserMessage"];
        <div class="alert @message.CssClassName" role="alert">
            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <strong>@message.Title</strong>
            @message.Message
        </div>
    }

Then if you want to throw an error message in your controller:

    TempData["UserMessage"] = new MessageViewModel() { CssClassName = "alert-danger  alert-dismissible", Title = "Error", Message = "This is an error message" };

MessageViewModel.cs:

public class MessageViewModel
    {
        public string CssClassName { get; set; }
        public string Title { get; set; }
        public string Message { get; set; }
    }

Note: Using Bootstrap 4 classes.

Use:

import matplotlib.pyplot as plt

plt.gcf().subplots_adjust(bottom=0.15)

to make room for the label.

Edit:

Since i gave the answer, matplotlib has added the tight_layout() function. So i suggest to use it:

plt.tight_layout()

should make room for the xlabel.

The form post values are stored under the name of the form in the request. For example, if you've overridden the getName() method of ContactType() to return "contact", you would do this:

$postData = $request->request->get('contact');
$name_value = $postData['name'];

If you're still having trouble, try doing a var_dump() on $request->request->all() to see all the post values.

Neevek's solution works better than Joel's on devices running 3.2 and above. There is a bug in Android that will cause java.lang.IllegalArgumentException: pointerIndex out of range if a gesture detector is used inside a scollview. To duplicate the issue, implement a custom scollview as Joel suggested and put a view pager inside. If you drag (don't lift you figure) to one direction (left/right) and then to the opposite, you will see the crash. Also in Joel's solution, if you drag the view pager by moving your finger diagonally, once your finger leave the view pager's content view area, the pager will spring back to its previous position. All these issues are more to do with Android's internal design or lack of it than Joel's implementation, which itself is a piece of smart and concise code.
