Programs & Examples On #Inetaddress

From the documentation of InetAddress.getByName(String host):

The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address. If a literal IP address is supplied, only the validity of the address format is checked.

So you can use it.

This can easily be done manually with the Windows Task Scheduler.

• First, install forever.

• Then, create a batch file that contains the following:

  cd C:\path\to\project\root
  call C:\Users\Username\AppData\Roaming\npm\forever.cmd start server.js
  exit 0
  

• Lastly, create a scheduled task that runs when you log on. This task should call the batch file.

I'm aware he's not asking for the inline version. But since this question has almost 100k visits and I fell here looking for that, I'll leave it here for the next fellow coder:

Make sure ESLint is not run with the --no-inline-config flag (if this doesn't sound familiar, you're likely good to go). Then, write this in your code file (for clarity and convention, it's written on top of the file but it'll work anywhere):

/* eslint-env browser */

This tells ESLint that your working environment is a browser, so now it knows what things are available in a browser and adapts accordingly.

There are plenty of environments, and you can declare more than one at the same time, for example, in-line:

/* eslint-env browser, node */

If you are almost always using particular environments, it's best to set it in your ESLint's config file and forget about it.

From their docs:

An environment defines global variables that are predefined. The available environments are:

• browser - browser global variables.
• node - Node.js global variables and Node.js scoping.
• commonjs - CommonJS global variables and CommonJS scoping (use this for browser-only code that uses Browserify/WebPack).
• shared-node-browser - Globals common to both Node and Browser.

[...]

Besides environments, you can make it ignore anything you want. If it warns you about using console.log() but you don't want to be warned about it, just inline:

/* eslint-disable no-console */

You can see the list of all rules, including recommended rules to have for best coding practices.

No, you can't. JavaScript is executed on the client side (browser), while the session data is stored on the server.

However, you can expose session variables for JavaScript in several ways:

• a hidden input field storing the variable as its value and reading it through the DOM API
• an HTML5 data attribute which you can read through the DOM
• storing it as a cookie and accessing it through JavaScript
• injecting it directly in the JS code, if you have it inline

In JSP you'd have something like:

<input type="hidden" name="pONumb" value="${sessionScope.pONumb} />

or:

<div id="product" data-prodnumber="${sessionScope.pONumb}" />

Then in JS:

// you can find a more efficient way to select the input you want
var inputs = document.getElementsByTagName("input"), len = inputs.length, i, pONumb;
for (i = 0; i < len; i++) {
    if (inputs[i].name == "pONumb") {
        pONumb = inputs[i].value;
        break;
    }
}

or:

var product = document.getElementById("product"), pONumb;
pONumb = product.getAttribute("data-prodnumber");

The inline example is the most straightforward, but if you then want to store your JavaScript code as an external resource (the recommended way) it won't be feasible.

<script>
    var pONumb = ${sessionScope.pONumb};
    [...]
</script>

You can use vanilla javascript by simply writing:

var width = el.clientWidth;

You could also use this to get the width of the document as follows:

var docWidth = document.documentElement.clientWidth || document.body.clientWidth;

Source: MDN

You can also get the width of the full window, including the scrollbar, as follows:

var fullWidth = window.innerWidth;

However this is not supported by all browsers, so as a fallback, you may want to use docWidth as above, and add on the scrollbar width.

And there might be some methods doing that in Excel.

In my case it was something else: the object I was saving should first have an id(e.g. save() should be called) before I could set any kind of relationship with it.

Use the Date object's getTime() method, which returns the number of milliseconds since 1 January 1970 00:00:00 UTC (epoch time):

var date = new Date();
var copiedDate = new Date(date.getTime());

In Safari 4, you can also write:

var date = new Date();
var copiedDate = new Date(date);

...but I'm not sure whether this works in other browsers. (It seems to work in IE8).

let me answer below question

Is there any difference between using an id attribute and using a name attribute on a <bean> tag,

There is no difference. you will experience same effect when id or name is used on a <bean> tag .

How?

Both id and name attributes are giving us a means to provide identifier value to a bean (For this moment, think id means id but not identifier). In both the cases, you will see same result if you call applicationContext.getBean("bean-identifier"); .

Take @Bean, the java equivalent of <bean> tag, you wont find an id attribute. you can give your identifier value to @Bean only through name attribute.

Let me explain it through an example :
Take this configuration file, let's call it as spring1.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
  <bean id="foo" class="com.intertech.Foo"></bean>
  <bean id="bar" class="com.intertech.Bar"></bean>
</beans>

Spring returns Foo object for, Foo f = (Foo) context.getBean("foo"); . Replace id="foo" with name="foo" in the above spring1.xml, You will still see the same result.

Define your xml configuration like,

<?xml version="1.0" encoding="UTF-8"?>
<beans ...>
  <bean id="fooIdentifier" class="com.intertech.Foo"></bean>
  <bean name="fooIdentifier" class="com.intertech.Foo"></bean>
</beans>

You will get BeanDefinitionParsingException. It will say, Bean name 'fooIdentifier' is already used in this element. By the way, This is the same exception you will see if you have below config
<bean name="fooIdentifier" class="com.intertech.Foo"></bean>
<bean name="fooIdentifier" class="com.intertech.Foo"></bean>


If you keep both id and name to the bean tag, the bean is said to have 2 identifiers. you can get the same bean with any identifier. take config as

<?xml version="1.0" encoding="UTF-8"?><br>
<beans ...>
  <bean id="fooById" name="fooByName" class="com.intertech.Foo"></bean>
  <bean id="bar" class="com.intertech.Bar"></bean>
</beans>

the following code prints true

FileSystemXmlApplicationContext context = new FileSystemXmlApplicationContext(...);
Foo fooById = (Foo) context.getBean("fooById")// returns Foo object;
Foo fooByName = (Foo) context.getBean("fooByName")// returns Foo object;
System.out.println(fooById == fooByName) //true

This answer is an update with a little more consideration for OOM and various other leaks.

Assumes you have a directory intended as the destination and a name String already defined.

    File destination = new File(directory.getPath() + File.separatorChar + filename);

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    source.compress(Bitmap.CompressFormat.PNG, 100, bytes);

    FileOutputStream fo = null;
    try {
        destination.createNewFile();

        fo = new FileOutputStream(destination);
        fo.write(bytes.toByteArray());
    } catch (IOException e) {

    } finally {
        try {
            fo.close();
        } catch (IOException e) {}
    }

create or replace procedure ex(j in number) as
i number;
begin
select id into i from student where id=j;
if i is not null then
dbms_output.put_line('exists');
end if;
exception
   when no_data_found then
        dbms_output.put_line(i||' does not exists');

end;

There's a few ways, the most prominent being getting form data, or getting the query string. Here's one method using JavaScript. When you click on a link it will call the _vals('mytarget', 'theval') which will submit the form data. When your page posts back you can check if this form data has been set and then retrieve it from the form values.

<script language="javascript" type="text/javascript">
 function _vals(target, value){
   form1.all("target").value=target;
   form1.all("value").value=value;
   form1.submit();
 }
</script>

Alternatively you can get it via the query string. PHP has your _GET and _SET global functions to achieve this making it much easier.

I'm sure there's probably more methods which are better, but these are just a few that spring to mind.

EDIT: Building on this from what others have said using the above method you would have an anchor tag like

<a onclick="_vals('name', 'val')" href="#">My Link</a>

And then in your PHP you can get form data using

$val = $_POST['value'];

So when you click on the link which uses JavaScript it will post form data and when the page posts back from this click you can then retrieve it from the PHP.

Use the basename command:

basename /home/user/new/*.txt

As of Node.js v6.0.0 using the constructor method has been deprecated and the following method should instead be used to construct a new buffer from a base64 encoded string:

var b64string = /* whatever */;
var buf = Buffer.from(b64string, 'base64'); // Ta-da

For Node.js v5.11.1 and below

Construct a new Buffer and pass 'base64' as the second argument:

var b64string = /* whatever */;
var buf = new Buffer(b64string, 'base64'); // Ta-da

If you want to be clean, you can check whether from exists :

if (typeof Buffer.from === "function") {
    // Node 5.10+
    buf = Buffer.from(b64string, 'base64'); // Ta-da
} else {
    // older Node versions, now deprecated
    buf = new Buffer(b64string, 'base64'); // Ta-da
}

Assuming nodeList = document.querySelectorAll("div"), this is a concise form of converting nodelist to array.

var nodeArray = [].slice.call(nodeList);

See me use it here.

This will do the trick:

  public void itemClicked(View v) {
    if (((CheckBox) v).isChecked()) {
        Toast.makeText(MyAndroidAppActivity.this,
           "Checked", Toast.LENGTH_LONG).show();
    }
  }

Try ejecting the config files, by running:

npm run eject

then you'll find a config folder created in your project. You will find your webpack config files init.

Because the first option is already selected, the change event is never fired. Add an empty value as the first one and check for empty in the location assignment.

Here's an example:

https://jsfiddle.net/bL5sq/

<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">_x000D_
  <option value="">Select...</option>_x000D_
  <option value="https://google.com">Google</option>_x000D_
  <option value="https://yahoo.com">Yahoo</option>_x000D_
</select>

Split creates an array . You can access the individual values by using a index.

var result=$(row).val().split('|')[2]
alert(result);

OR

var result=$(row).val().split('|');
alert(result[2]);

If it's input element then you need to use $(row).val() to get the value..

Otherwise you would need to use $(row).text() or $(row).html()

Just a note in case others have the same problem.

I had the same problem and found a different answer. I found that getting the height of a div that's height is determined by its contents needs to be initiated on window.load, or window.scroll not document.ready otherwise i get odd heights/smaller heights, i.e before the images have loaded. I also used outerHeight().

var currentHeight = 0;
$(window).load(function() {
    //get the natural page height -set it in variable above.

    currentHeight = $('#js_content_container').outerHeight();

    console.log("set current height on load = " + currentHeight)
    console.log("content height function (should be 374)  = " + contentHeight());   

});

SOLVED

Using IntelliJ

Select Build->Rebuild Project will solve it

Not as clean as bool(c) but it was an excuse to use ternary.

def myfunc(a,b):
    return True if a.intersection(b) else False

Also using a bit of the same logic there is no need to assign to c unless you are using it for something else.

def myfunc(a,b):
    return bool(a.intersection(b))

Finally, I would assume you want a True / False value because you are going to perform some sort of boolean test with it. I would recommend skipping the overhead of a function call and definition by simply testing where you need it.

Instead of:

if (myfunc(a,b)):
    # Do something

Maybe this:

if a.intersection(b):
    # Do something

Learn them and slowly you'll be able to reconize and figure out when to use them. Start with something simple as the singleton pattern :)

if you want to create one instance of an object and just ONE. You use the singleton pattern. Let's say you're making a program with an options object. You don't want several of those, that would be silly. Singleton makes sure that there will never be more than one. Singleton pattern is simple, used a lot, and really effective.

As soon as you're displaying content from another domain, you're basically trusting that domain not to serve-up malware.

There's nothing wrong with iframes per se. If you control the content of the iframe, they're perfectly safe.

str.matches(regex) behaves like Pattern.matches(regex, str) which attempts to match the entire input sequence against the pattern and returns

true if, and only if, the entire input sequence matches this matcher's pattern

Whereas matcher.find() attempts to find the next subsequence of the input sequence that matches the pattern and returns

true if, and only if, a subsequence of the input sequence matches this matcher's pattern

Thus the problem is with the regex. Try the following.

String test = "User Comments: This is \t a\ta \ntest\n\n message \n";

String pattern1 = "User Comments: [\\s\\S]*^test$[\\s\\S]*";
Pattern p = Pattern.compile(pattern1, Pattern.MULTILINE);
System.out.println(p.matcher(test).find());  //true

String pattern2 = "(?m)User Comments: [\\s\\S]*^test$[\\s\\S]*";
System.out.println(test.matches(pattern2));  //true

Thus in short, the (\\W)*(\\S)* portion in your first regex matches an empty string as * means zero or more occurrences and the real matched string is User Comments: and not the whole string as you'd expect. The second one fails as it tries to match the whole string but it can't as \\W matches a non word character, ie [^a-zA-Z0-9_] and the first character is T, a word character.

As Mystere Man suggested, getting just a view first and then again making an ajax call again to get the json result is unnecessary in this case. that is 2 calls to the server. I think you can directly return an HTML table of Users in the first call.

We will do this in this way. We will have a strongly typed view which will return the markup of list of users to the browser and this data is being supplied by an action method which we will invoke from our browser using an http request.

Have a ViewModel for the User

public class UserViewModel
{
  public int UserID { set;get;}
  public string FirstName { set;get;}
   //add remaining properties as per your requirement

}

and in your controller have a method to get a list of Users

public class UserController : Controller
{

   [HttpGet]
   public ActionResult List()
   {
     List<UserViewModel> objList=UserService.GetUsers();  // this method should returns list of  Users
     return View("users",objList)        
   }
}

Assuming that UserService.GetUsers() method will return a List of UserViewModel object which represents the list of usres in your datasource (Tables)

and in your users.cshtml ( which is under Views/User folder),

 @model List<UserViewModel>

 <table>

 @foreach(UserViewModel objUser in Model)
 {
   <tr>
      <td>@objUser.UserId.ToString()</td>
      <td>@objUser.FirstName</td>
   </tr>
 }
 </table>

All Set now you can access the url like yourdomain/User/List and it will give you a list of users in an HTML table.

use this code it is working

In android google maps application there is a very easy way to find distance between 2 locations, to do so follow the following easy steps:

1. when you first open the app go to " your timeline " from the drop menue on the top left.

2. once the new windwo opens, chose from the settings on your top right menue and choose "add place".

3. add your places and name them lilke point 1 , point 2 , or any easy name to remember.
4. once your places are added and flagged go back to the main Window in your google app.
5. click on the blue circle with the arrow in your bottom right.
6. a new windwo will open and you can see on the top there are two text fields in which you can add your "from location" and "distance location".
7. click on any text field and type in your saved location in point 3.
8. click on the other text field and add your next saved location.
9. By doing so, google maps will calculate the distance between the two locations and show you the blue path on map ..

Good luck

The option you're looking for is -R.

cp -R path_to_source path_to_destination/

• If destination doesn't exist, it will be created.
• -R means copy directories recursively. You can also use -r since it's case-insensitive.
• Note the nuances with adding the trailing / as per @muni764's comment.

The other answers are very useful, thanks to the authors!

But I could not see how to customise the rectangle when highlighting an item upon selection rather than disabling the highlighting @alvins @bharat dojeha.

The following works for me to create a rounded list view item container with no outline and a lighter grey when selected of the same shape:

Your xml needs to contain a selector such as e.g. ( in res/drawable/customshape.xml):

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" >
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <stroke android:width="8dp" android:color="@android:color/transparent" />
        <padding android:left="14dp" android:top="14dp"
                android:right="14dp" android:bottom="14dp" />
        <corners android:radius="10dp" />
        <gradient 
             android:startColor="@android:color/background_light"
             android:endColor="@android:color/transparent" 
             android:angle="225"/> 
    </shape>
</item>
<item android:state_pressed="false">
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <stroke android:width="8dp" android:color="@android:color/transparent" />
        <padding android:left="14dp" android:top="14dp"
                android:right="14dp" android:bottom="14dp" />
        <corners android:radius="10dp" />
        <gradient 
             android:startColor="@android:color/darker_gray"
             android:endColor="@android:color/transparent" 
             android:angle="225"/> 
    </shape>        
</item>

Then you need to implement a list adapter and override the getView method to set the custom selector as background

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        //snip
        convertView.setBackgroundResource(R.drawable.customshape);
        //snip
    }

and need to also 'hide' the default selector rectangle e.g in onCreate (I also hide my thin grey divider line between the items):

listView.setSelector(android.R.color.transparent);
listview.setDivider(null);

This approach solves a general solution for drawables, not just ListViewItem with various selection states.

"WORKSPACE" environment variable works for the latest version of Jenkins Pipeline. You can use this in your Jenkins file: "${env.WORKSPACE}"

Sample use below:

def files = findFiles glob: '**/reports/*.json'
for (def i=0; i<files.length; i++) {
jsonFilePath = "${files[i].path}"       
jsonPath = "${env.WORKSPACE}" + "/" + jsonFilePath
echo jsonPath

hope that helps!!

Had the same issue with Ionic routing.

Simple solution is to use the name of the state - basically state.go(state name)

.state('tab.search', {
    url: '/search',
    views: {
      'tab-search': {
        templateUrl: 'templates/search.html',
        controller: 'SearchCtrl'
      }
    }
  })

And in controller you can use $state.go('tab.search');

PostgreSQL 12 supports generated columns:

PostgreSQL 12 Beta 1 Released!

Generated Columns

PostgreSQL 12 allows the creation of generated columns that compute their values with an expression using the contents of other columns. This feature provides stored generated columns, which are computed on inserts and updates and are saved on disk. Virtual generated columns, which are computed only when a column is read as part of a query, are not implemented yet.

Generated Columns

A generated column is a special column that is always computed from other columns. Thus, it is for columns what a view is for tables.

CREATE TABLE people (
    ...,
    height_cm numeric,
    height_in numeric GENERATED ALWAYS AS (height_cm * 2.54) STORED
);

Yes, it will serialize and deserialize a List<>. Just make sure you use the [XmlArray] attribute if in doubt.

[Serializable]
public class A
{
    [XmlArray]
    public List<string> strings;
}

This works with both Serialize() and Deserialize().

if you use docker-compose.ymlfile:

services:
    varnish:
        ports:
            - 80
            - 6081

You can also specify the host/network port as HOST/NETWORK_PORT:CONTAINER_PORT

varnish:
    ports:
        - 81:80
        - 6081:6081

The original code is from Sabry Suleiman.

Made it a bit prettier:

function is_session_started() {

    if ( php_sapi_name() === 'cli' )
        return false;

    return version_compare( phpversion(), '5.4.0', '>=' )
        ? session_status() === PHP_SESSION_ACTIVE
        : session_id() !== '';
}

First condition checks the Server API in use. If Command Line Interface is used, the function returns false.

Then we return the boolean result depending on the PHP version in use.

In ancient history you simply needed to check session_id(). If it's an empty string, then session is not started. Otherwise it is.

Since 5.4 to at least the current 8.0 the norm is to check session_status(). If it's not PHP_SESSION_ACTIVE, then either the session isn't started yet (PHP_SESSION_NONE) or sessions are not available altogether (PHP_SESSION_DISABLED).

Deleting Elements in an Array if Element is a Certain value VBA

to delete elements in an Array wih certain condition, you can code like this

For i = LBound(ArrValue, 2) To UBound(ArrValue, 2)
    If [Certain condition] Then
        ArrValue(1, i) = "-----------------------"
    End If
Next i

StrTransfer = Replace(Replace(Replace(join(Application.Index(ArrValue(), 1, 0), ","), ",-----------------------,", ",", , , vbBinaryCompare), "-----------------------,", "", , , vbBinaryCompare), ",-----------------------", "", , , vbBinaryCompare)
ResultArray = join( Strtransfer, ",")

I often manipulate 1D-Array with Join/Split but if you have to delete certain value in Multi Dimension I suggest you to change those Array into 1D-Array like this

strTransfer = Replace(Replace(Replace(Replace(Names.Add("A", MultiDimensionArray), Chr(34), ""), "={", ""), "}", ""), ";", ",")
'somecode to edit Array like 1st code on top of this comment
'then loop through this strTransfer to get right value in right dimension
'with split function.

res = request.GET['paymentid'] will raise a KeyError if paymentid is not in the GET data.

Your sample php code checks to see if paymentid is in the POST data, and sets $payID to '' otherwise:

$payID = isset($_POST['paymentid']) ? $_POST['paymentid'] : ''

The equivalent in python is to use the get() method with a default argument:

payment_id = request.POST.get('payment_id', '')

while debugging, this is what I see in the response.GET: <QueryDict: {}>, request.POST: <QueryDict: {}>

It looks as if the problem is not accessing the POST data, but that there is no POST data. How are you are debugging? Are you using your browser, or is it the payment gateway accessing your page? It would be helpful if you shared your view.

Once you are managing to submit some post data to your page, it shouldn't be too tricky to convert the sample php to python.

On 32-bit machine sizeof pointer is 32 bits ( 4 bytes), while on 64 bit machine it's 8 byte. Regardless of what data type they are pointing to, they have fixed size.

To pass the source element in Angular 5 :

<input #myInput type="text" (change)="someFunction(myInput)">

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

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

Not sure this answers the question but I believe it's worth mentioning here. There is one more way for selecting single field (and not multiple) using db.collection_name.distinct();

e.g.,db.student.distinct('roll',{});

Or, 2nd way: Using db.collection_name.find().forEach(); (multiple fields can be selected here by concatenation)

e.g., db.collection_name.find().forEach(function(c1){print(c1.roll);});

This code achieves what you want --- also its weird and certainly buggy:

I observed that it works when:

a) you specify the index_col rel. to the number of columns you really use -- so its three columns in this example, not four (you drop dummy and start counting from then onwards)

b) same for parse_dates

c) not so for usecols ;) for obvious reasons

d) here I adapted the names to mirror this behaviour

import pandas as pd
from StringIO import StringIO

csv = """dummy,date,loc,x
bar,20090101,a,1
bar,20090102,a,3
bar,20090103,a,5
bar,20090101,b,1
bar,20090102,b,3
bar,20090103,b,5
"""

df = pd.read_csv(StringIO(csv),
        index_col=[0,1],
        usecols=[1,2,3], 
        parse_dates=[0],
        header=0,
        names=["date", "loc", "", "x"])

print df

which prints

                x
date       loc   
2009-01-01 a    1
2009-01-02 a    3
2009-01-03 a    5
2009-01-01 b    1
2009-01-02 b    3
2009-01-03 b    5

You have to use the jquery's text() function. What it does is:

Get the combined text contents of all matched elements.

The result is a string that contains the combined text contents of all matched elements. This method works on both HTML and XML documents. Cannot be used on input elements. For input field text use the val attribute.

For example:

Find the text in the first paragraph (stripping out the html), then set the html of the last paragraph to show it is just text (the bold is gone).

var str = $("p:first").text();
$("p:last").html(str);

Test Paragraph.

Test Paragraph.

With your markup you have to do:

$('a#a_tbnotesverbergen').text('new text');

and it will result in

<a id="a_tbnotesverbergen" href="#nothing">new text</a>

This simple way worked fine for me:

<ul style="margin-top:-30px;">

For best performance, here is what I wrote :
(see execution plan)

DELETE FROM your_table
WHERE rowid IN 
  (select t1.rowid from your_table  t1
      LEFT OUTER JOIN (
      SELECT MIN(rowid) as rowid, column1,column2, column3
      FROM your_table 
      GROUP BY column1, column2, column3
  )  co1 ON (t1.rowid = co1.rowid)
  WHERE co1.rowid IS NULL
);

In my case where I had the problem I was referring to a module when I tried extending the class.

import logging
class UserdefinedLogging(logging):

If you look at the Documentation Info, you'll see "logging" displayed as module.

In this specific case I had to simply inherit the logging module to create an extra class for the logging.

document.getElementById("fname").style.borderTopColor = 'red';
document.getElementById("fname").style.borderBottomColor = 'red';

Add header:

#include<math.h>

Note: use abs(), sometimes at the time of evaluation sqrt() can take negative values which leave to domain error.

abs()- provides absolute values;

example, abs(-3) =3

Include -lm at the end of your command during compilation time:

gcc <filename.extension> -lm

Regarding @Jon_Schneider's comment, if the column has blank cells just use COUNTA()

=INDEX(G2:G; COUNT**A**(G2:G))

You should never use the unidirectional @OneToMany annotation because:

1. It generates inefficient SQL statements
2. It creates an extra table which increases the memory footprint of your DB indexes

Now, in your first example, both sides are owning the association, and this is bad.

While the @JoinColumn would let the @OneToMany side in charge of the association, it's definitely not the best choice. Therefore, always use the mappedBy attribute on the @OneToMany side.

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<APost> aPosts;

    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<BPost> bPosts;
}

public class BPost extends Post {

    @ManyToOne(fetch=FetchType.LAZY)    
    public User user;
}

public class APost extends Post {

     @ManyToOne(fetch=FetchType.LAZY) 
     public User user;
}

In code, you need to explicitly create a Brush instance:

Fill = new SolidColorBrush(Color.FromArgb(0xff, 0xff, 0x90))

It's the end statement for the alternative syntax:

foreach ($foo as $bar) :
    ...
endforeach;

Useful to make code more readable if you're breaking out of PHP:

<?php foreach ($foo as $bar) : ?>
    <div ...>
        ...
    </div>
<?php endforeach; ?>

Open a new Search pane in Developer Tools by:

• pressing Ctrl+Shift+F (Cmd+Option+I on mac)
• clicking the overflow menu (?) in DevTools,
• clicking the overflow menu in the Console (?) and choosing the Search option

You can search across all your scripts with support for regular expressions and case sensitivity.

Click any match to load that file/section in the scripts panel.

Make sure 'Search in anonymous and content scripts' is checked in the DevTools Preferences (F1). This will return results from within iframes and HTML inline scripts:

For some kinda simple things like that You can easily use Wrap look at that example

    Wrap(
       crossAxisAlignment: WrapCrossAlignment.start,
       alignment: WrapAlignment.center,
       direction: Axis.vertical,
       spacing: 30, // to apply margin in the main axis of the wrap
       runSpacing: 30, // to apply margin in the cross axis of the wrap
       children: <Widget>[
        Text('Text 1'),
        Text('Text 2')
  ]
)

A view is simply any SELECT query that has been given a name and saved in the database. For this reason, a view is sometimes called a named query or a stored query. To create a view, you use the SQL syntax:

     CREATE OR REPLACE VIEW <view_name> AS
     SELECT <any valid select query>;

Another late answer:

If you are trying to make a hot copy of server database (in a linux environment) and the database engine of all tables is MyISAM you should use mysqlhotcopy.

Acordingly to documentation:

It uses FLUSH TABLES, LOCK TABLES, and cp or scp to make a database backup. It is a fast way to make a backup of the database or single tables, but it can be run only on the same machine where the database directories are located. mysqlhotcopy works only for backing up MyISAM and ARCHIVE tables.

The LOCK TABLES time depends of the time the server can copy MySQL files (it doesn't make a dump).

It's also possible to use jQuery's .load()

$('#submitform').click(function() {
  $('#showresults').load('getinfo.asp #showresults', {
    txtsearch: $('#appendedInputButton').val()
  }, function() {
    // alert('Load was performed.')
    // $('#showresults').slideDown('slow')
  });
});

unlike $.get(), allows us to specify a portion of the remote document to be inserted. This is achieved with a special syntax for the url parameter. If one or more space characters are included in the string, the portion of the string following the first space is assumed to be a jQuery selector that determines the content to be loaded.

We could modify the example above to use only part of the document that is fetched:

$( "#result" ).load( "ajax/test.html #container" );

When this method executes, it retrieves the content of ajax/test.html, but then jQuery parses the returned document to find the element with an ID of container. This element, along with its contents, is inserted into the element with an ID of result, and the rest of the retrieved document is discarded.

Set the data as a vector and then place in the function.

Declaring the field as 'final' will ensure that the field is a constant and cannot change. The difference comes in the usage of 'static' keyword.

Declaring a field as static means that it is associated with the type and not with the instances. i.e. only one copy of the field will be present for all the objects and not individual copy for each object. Due to this, the static fields can be accessed through the class name.

As you can see, your requirement that the field should be constant is achieved in both cases (declaring the field as 'final' and as 'static final').

Similar question is private final static attribute vs private final attribute

For anyone struggling with this, I tried the mentioned options without success. Turns out all I needed to do was just quit and relaunch Xcode. Simple things can be annoying sometimes.

just fetch specific node data and its working perfect for me

mFirebaseInstance.getReference("yourNodeName").getRef().addValueEventListener(new ValueEventListener() {

        for (DataSnapshot postSnapshot : dataSnapshot.getChildren()) {
            Log.e(TAG, "======="+postSnapshot.child("email").getValue());
            Log.e(TAG, "======="+postSnapshot.child("name").getValue());
        }
    }

    @Override

        // Failed to read value
        Log.e(TAG, "Failed to read app title value.", error.toException());
    }
});

There is an important part of the conversation surrounding lexical and dynamic scoping that is missing: a plain explanation of the lifetime of the scoped variable - or when the variable can be accessed.

Dynamic scoping only very loosely corresponds to "global" scoping in the way that we traditionally think about it (the reason I bring up the comparison between the two is that it has already been mentioned - and I don't particularly like the linked article's explanation); it is probably best we don't make the comparison between global and dynamic - though supposedly, according to the linked article, "...[it] is useful as a substitute for globally scoped variables."

So, in plain English, what's the important distinction between the two scoping mechanisms?

Lexical scoping has been defined very well throughout the answers above: lexically scoped variables are available - or, accessible - at the local level of the function in which it was defined.

However - as it is not the focus of the OP - dynamic scoping has not received a great deal of attention and the attention it has received means it probably needs a bit more (that's not a criticism of other answers, but rather a "oh, that answer made we wish there was a bit more"). So, here's a little bit more:

Dynamic scoping means that a variable is accessible to the larger program during the lifetime of the function call - or, while the function is executing. Really, Wikipedia actually does a nice job with the explanation of the difference between the two. So as not to obfuscate it, here is the text that describes dynamic scoping:

...[I]n dynamic scoping (or dynamic scope), if a variable name's scope is a certain function, then its scope is the time-period during which the function is executing: while the function is running, the variable name exists, and is bound to its variable, but after the function returns, the variable name does not exist.

I have searched long and hard for an answer to this question. From what I gather Google did that on purpose once people used the internet connection to add spam comments to the market. However, I did find a guy who had done it and was willing to share the required images. The linked AVD runs(for me) both the market and browser internet.

NOTE: It looks like it's just going to fix the market. But the market won't run without internet, so if the market is fixed, the browser internet will work too. I downloaded the linked files myself and it showed the internet in the browser perfectly.

Try cloning before doing the checkout.

do git clone "whee to find it" then after cloning check out the branch

It should also be mentioned, that Set-PSDebug is similar to the old-school echo on batch command:

Set-PSDebug -Trace 1

This command will result in showing every line of the executing script:

When the Trace parameter has a value of 1, each line of script is traced as it runs. When the parameter has a value of 2, variable assignments, function calls, and script calls are also traced. If the Step parameter is specified, you're prompted before each line of the script runs.

Just putting it in src/main/resources will bundle it inside the artifact. E.g. if your artifact is a JAR, you will have the log4j.properties file inside it, losing its initial point of making logging configurable.

I usually put it in src/main/resources, and set it to be output to target like so:

<build>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <targetPath>${project.build.directory}</targetPath>
            <includes>
                <include>log4j.properties</include>
            </includes>
        </resource>
    </resources>
</build>

Additionally, in order for log4j to actually see it, you have to add the output directory to the class path. If your artifact is an executable JAR, you probably used the maven-assembly-plugin to create it. Inside that plugin, you can add the current folder of the JAR to the class path by adding a Class-Path manifest entry like so:

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
        <archive>
            <manifest>
                <mainClass>com.your-package.Main</mainClass>
            </manifest>
            <manifestEntries>
                <Class-Path>.</Class-Path>
            </manifestEntries>
        </archive>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id> <!-- this is used for inheritance merges -->
            <phase>package</phase> <!-- bind to the packaging phase -->
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Now the log4j.properties file will be right next to your JAR file, independently configurable.

To run your application directly from Eclipse, add the resources directory to your classpath in your run configuration: Run->Run Configurations...->Java Application->New select the Classpath tab, select Advanced and browse to your src/resources directory.

This can be more complicated than it looks depending on how you want to count things. For instance, if you have a list of ints, do you want the size of the list containing the references to the ints? (ie. list only, not what is contained in it), or do you want to include the actual data pointed to, in which case you need to deal with duplicate references, and how to prevent double-counting when two objects contain references to the same object.

You may want to take a look at one of the python memory profilers, such as pysizer to see if they meet your needs.

I would like to recommend a single header C++ 11 YAML parser mini-yaml.

A quick-start example taken from the above repository.

file.txt

key: foo bar
list:
  - hello world
  - integer: 123
    boolean: true

.cpp

Yaml::Node root;
Yaml::Parse(root, "file.txt");

// Print all scalars.
std::cout << root["key"].As<std::string>() << std::endl;
std::cout << root["list"][0].As<std::string>() << std::endl;
std::cout << root["list"][1]["integer"].As<int>() << std::endl;
std::cout << root["list"][1]["boolean"].As<bool>() << std::endl;

// Iterate second sequence item.
Node & item = root[1];
for(auto it = item.Begin(); it != item.End(); it++)
{
    std::cout << (*it).first << ": " << (*it).second.As<string>() << std::endl;
}

Output

foo bar
hello world
123
1
integer: 123
boolean: true

Joe Edel's answer to himself is actually the right approach to resolve the pivot problem.

Basically the idea is to list out the columns in the base table firstly, and then any number of options.value from the joint option table. Just left join the same option table multiple times in order to get all the options.

What needs to be done by the programming language is to build this query dynamically according to a list of options needs to be queried.

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

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

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

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

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

chrCode = keyCode

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

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

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

$('#grid').trigger( 'reloadGrid' );

it is too late I know, howewer there is no succesfully answer. I found the answer from another website. I fixed the issue when I delete the System.Runtime assemblydependency. I deleted this.

This could be useful for someone else. I'm using DatatablesJS. I add 500px to the current height of the table. I do this because Datatables allow you to use 10, 20, etc pages in your table. So I need to calculate dinamically the table's height.
When dropdown is shown, I add extra height.
When dropdown is hiden, I reset original table's height.

$(document).ready(function() {
    $('.table-responsive .dropdown').on('shown.bs.dropdown', function () {
          console.log($('#table-responsive-cliente').height() + 500)
          $("#table-responsive-cliente").css("height",$('#table-responsive-cliente').height() + 500 );
    })

    $('.table-responsive .dropdown').on('hide.bs.dropdown', function () {
           $("#table-responsive-cliente").css("height","auto");
    })
})

And the HTML

<div class="table-responsive" id="table-responsive-cliente">
    <table class="table-striped table-hover">
     ....

     ....
    </table>
</div>

Before:

After dropdown is shown:

You can also use nuget: https://www.nuget.org/packages/System.Management.Automation/ It is maybe a better option.

Then run:

ssh-keyscan -t rsa bitbucket.org >>~/.ssh/known_hosts
python --win known_hosts.py >known_hosts.reg
start known_hosts.reg

And choose to import into the registry. The keyscan will retrieve the public key for the domain (I had my problems with bitbucket), and then the python script will convert it to Plink format.

This happened to me when an web request endpoint was switched to another server that accepted TLS1.2 requests only. Tried so many attempts mostly found on Stackoverflow like

1. Registry Keys ,
2. Added :
   System.Net.ServicePointManager.SecurityProtocol |= System.Net.SecurityProtocolType.Tls12; to Global.ASX OnStart,
3. Added in Web.config.
4. Updated .Net framework to 4.7.2 Still getting same Exception.

The exception received did no make justice to the actual problem I was facing and found no help from the service operator.

To solve this I have to add a new Cipher Suite TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 I have used IIS Crypto 2.0 Tool from here as shown below.

This can be a quick hack to connect hive and python,

Also you can use DownloadFileAsync method in WebClient class. It downloads to a local file the resource with the specified URI. Also this method does not block the calling thread.

Sample:

    webClient.DownloadFileAsync(new Uri("http://www.example.com/file/test.jpg"), "test.jpg");

For more information:

http://csharpexamples.com/download-files-synchronous-asynchronous-url-c/

The value you have passed as the file descriptor is not valid. It is either negative or does not represent a currently open file or socket.

So you have either closed the socket before calling write() or you have corrupted the value of 'sockfd' somewhere in your code.

It would be useful to trace all calls to close(), and the value of 'sockfd' prior to the write() calls.

Your technique of only printing error messages in debug mode seems to me complete madness, and in any case calling another function between a system call and perror() is invalid, as it may disturb the value of errno. Indeed it may have done so in this case, and the real underlying error may be different.

[k for k,v in l if v =='delicia']

here l is the list of tuples-[(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")]

And instead of converting it to a dict, we are using llist comprehension.

*Key* in Key,Value in list, where value = **delicia**

You're forgetting the number one reason to include this information. It has nothing to do with you, the programmer. It has everything to do with the person coming down the road 2 or 3 years after you leave the company who has to read that stuff.

Yes, an IDE will quickly identify types for you. However, when you're reading through some long batches of 'business rules' code, it's nice to not have to pause on each variable to find out what type it is. When I see things like strUserID, intProduct or guiProductID, it makes for much easier 'ramp up' time.

I agree that MS went way too far with some of their naming conventions - I categorize that in the "too much of a good thing" pile.

Naming conventions are good things, provided you stick to them. I've gone through enough old code that had me constantly going back to look at the definitions for so many similarly-named variables that I push "camel casing" (as it was called at a previous job). Right now I'm on a job that has many thousand of lines of completely uncommented classic ASP code with VBScript and it's a nightmare trying to figure things out.

Actions

ADD_PRODUCT : (context,product) => {
  return Axios.post(uri, product).then((response) => {
    if (response.status === 'success') {  
      context.commit('SET_PRODUCT',response.data.data)
    }
    return response.data
  });
});

Component

this.$store.dispatch('ADD_PRODUCT',data).then((res) => {
  if (res.status === 'success') {
    // write your success actions here....
  } else {
     // write your error actions here...
  }
})

<input type="hidden" id="CDate" value="<%=DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")%>" />

In order to convert the date to JS date(all numbers):

var JSDate = $("#CDate").val();
JSDate = Date.parse(JSDate);

Not elegant, but if you don't use your method overlappingly you can also use global variables, defined by the Public statement at the beginning of your code, before the Subs. You have to be cautious though, once you change a public value, it will be held throughout your code in all Subs and Functions.

This worked for me while searching for value less than or equal than now:

db.collectionName.find({ "dt": { "$lte" : new Date() + "" } });

var result = string.Join(",", arr);

This uses the following overload of string.Join:

public static string Join<T>(string separator, IEnumerable<T> values);

Step 1 :

Create ts : app/_helpers/must-match.validator.ts

import { FormGroup } from '@angular/forms';

export function MustMatch(controlName: string, matchingControlName: string) {
    return (formGroup: FormGroup) => {
        const control = formGroup.controls[controlName];
        const matchingControl = formGroup.controls[matchingControlName];

        if (matchingControl.errors && !matchingControl.errors.mustMatch) { 
            return;
        } 
        if (control.value !== matchingControl.value) {
            matchingControl.setErrors({ mustMatch: true });
        } else {
            matchingControl.setErrors(null);
        }
    }
}

Step 2 :

Use in your component.ts

import { MustMatch } from '../_helpers/must-match.validator'; 

ngOnInit() {
    this.loginForm = this.formbuilder.group({
      Password: ['', [Validators.required, Validators.minLength(6)]], 
      ConfirmPassword: ['', [Validators.required]],
    }, {
      validator: MustMatch('Password', 'ConfirmPassword')
    });
  } 

Step 3 :

Use In View/Html

<input type="password" formControlName="Password" class="form-control" autofocus>
                <div *ngIf="loginForm.controls['Password'].invalid && (loginForm.controls['Password'].dirty || loginForm.controls['Password'].touched)" class="alert alert-danger">
                    <div *ngIf="loginForm.controls['Password'].errors.required">Password Required. </div> 
                    <div *ngIf="loginForm.controls['Password'].errors.minlength">Password must be at least 6 characters</div>
                </div> 


 <input type="password" formControlName="ConfirmPassword" class="form-control" >
                <div *ngIf="loginForm.controls['ConfirmPassword'].invalid && (loginForm.controls['ConfirmPassword'].dirty || loginForm.controls['ConfirmPassword'].touched)" class="alert alert-danger">
                    <div *ngIf="loginForm.controls['ConfirmPassword'].errors.required">ConfirmPassword Required. </div> 
                    <div *ngIf="loginForm.controls['ConfirmPassword'].errors.mustMatch">Your password and confirmation password do not match.</div>
                </div> 

var numArray = [140000, 104, 99];
numArray = numArray.sort((a,b) => a-b);
alert(numArray)

I've recently tried Retrofit Library from square, Its great and you can call your rest API very easily. Annotation based configuration allows us to get rid of lot of boiler plate coding.

public List<SomeClass> TheMethod(SomeParameter)
{
  using (MyDC TheDC = new MyDC())
  {
     var TheQueryFromDB = (....
                           select new SomeClass{ SomeVariable = ....,
                                        AnotherVariable = ....}
                           ).ToList();

      return TheQueryFromDB.ToList();
    }
}

public class SomeClass{
   public string SomeVariable{get;set}
   public string AnotherVariable{get;set;}
}

Creating your own class and querying for it is the best solution I know.As much as I know you can not use anonymous type return values in another method, because it won't just be recognized.However, they can be used in the same method. I used to return them as IQueryable or IEnumerable, though it still does not let you see what is inside of the anonymous type variable.

I run into something like this before while I was trying to refactor some code, you can check it here : Refactoring and creating separate methods

I think curl --verbose/-v is the easiest. It will spit out the request headers (lines prefixed with '>') without having to write to a file:

You can do that by using following code

$('#button_id').on('click', function(){
$('#element_want_to_target').addClass('.animation_class');});

The typical form for dynamically allocating an NxM array of type T is

T **a = malloc(sizeof *a * N);
if (a)
{
  for (i = 0; i < N; i++)
  {
    a[i] = malloc(sizeof *a[i] * M);
  }
}

If each element of the array has a different length, then replace M with the appropriate length for that element; for example

T **a = malloc(sizeof *a * N);
if (a)
{
  for (i = 0; i < N; i++)
  {
    a[i] = malloc(sizeof *a[i] * length_for_this_element);
  }
}

None of the methods worked for me as i needed to pull the image from a folder instead of adding it to the application. The below code worked:

TestImage.Source = GetImage("/Content/Images/test.png")

private static BitmapImage GetImage(string imageUri)
{
    var bitmapImage = new BitmapImage();
    
    bitmapImage.BeginInit();
    bitmapImage.UriSource = new Uri("pack://siteoforigin:,,,/" + imageUri,             UriKind.RelativeOrAbsolute);
    bitmapImage.EndInit();
    
    return bitmapImage;
} 

You have Two alternatives :

First one is to create a ServletImageLoader that would take as a parameter an identifier of your image (the path of the image or a hash) that you will use inside the Servlet to handle your image, and it will print to the response stream the loaded image from the server.

Second one is to create a folder inside your application's ROOT folder and just save the relative path to your images.

int elem = 42;
std::vector<int> v;
v.push_back(elem);
if(std::find(v.begin(), v.end(), elem) != v.end())
{
  //elem exists in the vector
} 

It is used in the stack unwiding tables, which you can see for instance in the assembly output of my answer to another question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.

The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then you will see it misbehave.

Of course, if nothing is using exceptions, you can disable them with -fno-exceptions (and if nothing is using RTTI, you can also add -fno-rtti). If you are using them, you have to (as other answers already noted) link with g++ instead of gcc, which will add -lstdc++ for you.

            let mainQueue = dispatch_get_main_queue()

            dispatch_after(delayInNanoSeconds, mainQueue, {

                print("Some UI related task after delay")
            })

In swift 3.0 :

            let dispatchTime: DispatchTime = DispatchTime.now() + Double(Int64(2.0 * Double(NSEC_PER_SEC))) / Double(NSEC_PER_SEC)
            DispatchQueue.main.asyncAfter(deadline: dispatchTime, execute: {

          })

Not 100% sure what you mean:

Trusted_Connection=True;

IS using Windows credentials and is 100% equivalent to:

Integrated Security=SSPI;

or

Integrated Security=true;

If you don't want to use integrated security / trusted connection, you need to specify user id and password explicitly in the connection string (and leave out any reference to Trusted_Connection or Integrated Security)

server=yourservername;database=yourdatabase;user id=YourUser;pwd=TopSecret

Only in this case, the SQL Server authentication mode is used.

If any of these two settings is present (Trusted_Connection=true or Integrated Security=true/SSPI), then the Windows credentials of the current user are used to authenticate against SQL Server and any user iD= setting will be ignored and not used.

For reference, see the Connection Strings site for SQL Server 2005 with lots of samples and explanations.

Using Windows Authentication is the preferred and recommended way of doing things, but it might incur a slight delay since SQL Server would have to authenticate your credentials against Active Directory (typically). I have no idea how much that slight delay might be, and I haven't found any references for that.

Summing up:

If you specify either Trusted_Connection=True; or Integrated Security=SSPI; or Integrated Security=true; in your connection string

==> THEN (and only then) you have Windows Authentication happening. Any user id= setting in the connection string will be ignored.

If you DO NOT specify either of those settings,

==> then you DO NOT have Windows Authentication happening (SQL Authentication mode will be used)

Try using How to recover a dropped stash in Git? to find the stash you popped. I think there are always two commits for a stash, since it preserves the index and the working copy (so often the index commit will be empty). Then git show them to see the diff and use patch -R to unapply them.

def chunk(lst):
    out = []
    for x in xrange(2, len(lst) + 1):
        if not len(lst) % x:
            factor = len(lst) / x
            break
    while lst:
        out.append([lst.pop(0) for x in xrange(factor)])
    return out

Here's making the indexes unusable without the file:

DECLARE
  CURSOR  usr_idxs IS select * from user_indexes;
  cur_idx  usr_idxs% ROWTYPE;
  v_sql  VARCHAR2(1024);

BEGIN
  OPEN usr_idxs;
  LOOP
    FETCH usr_idxs INTO cur_idx;
    EXIT WHEN NOT usr_idxs%FOUND;

    v_sql:= 'ALTER INDEX ' || cur_idx.index_name || ' UNUSABLE';
    EXECUTE IMMEDIATE v_sql;
  END LOOP;
  CLOSE usr_idxs;
END;

The rebuild would be similiar.

You can get something suitable for that purpose with:

id(self)

This is a Task that is returning a Task of type String (C# anonymous function or in other word a delegation is used 'Func')

    public static async Task<string> MyTask()
    {
        //C# anonymous AsyncTask
        return await Task.FromResult<string>(((Func<string>)(() =>
        {
            // your code here
            return  "string result here";

        }))());
    }

Best way to convince... find a bug, write a unit test for it, fix the bug.

That particular bug is unlikely to ever appear again, and you can prove it with your test.

If you do this enough, others will catch on quickly.

If you use sql server Management studio go to Tools >> Options >> Designers and uncheck “Prevent Saving changes that require table re-creation” It works with me

Instance methods => invoked on specific instance of a specific class. Method wants to know upon which class it was invoked. The way it happens there is a invisible parameter called 'this'. Inside of 'this' we have members of instance class already set with values. 'This' is not a variable. It's a value, you cannot change it and the value is reference to the receiver of the call. Ex: You call repairmen(instance method) to fix your TV(actual program). He comes with tools('this' parameter). He comes with specific tools needed for fixing TV and he can fix other things also.

In static methods => there is no such thing as 'this'. Ex: The same repairman (static method). When you call him you have to specify which repairman to call(like electrician). And he will come and fix your TV only. But, he doesn't have tools to fix other things (there is no 'this' parameter).

Static methods are usually useful for operations that don't require any data from an instance of the class (from 'this') and can perform their intended purpose solely using their arguments.

In short - JSON is a way of serializing in such a way, that it becomes JavaScript code. When executed (with eval or otherwise), this code creates and returns a JavaScript object which contains the data you serialized. This is available because JavaScript allows the following syntax:

var MyArray = [ 1, 2, 3, 4]; // MyArray is now an array with 4 elements
var MyObject = {
    'StringProperty' : 'Value',
    'IntProperty' : 12,
    'ArrayProperty' : [ 1, 2, 3],
    'ObjectProperty' : { 'SubObjectProperty': 'SomeValue' }
}; // MyObject is now an object with property values set.

You can use this for several purposes. For one, it's a comfortable way to pass data from your server backend to your JavaScript code. Thus, this is often used in AJAX.

You can also use it as a standalone serialization mechanism, which is simpler and takes up less space than XML. Many libraries exists that allow you to serialize and deserialize objects in JSON for various programming languages.

Christoph's answer is perfect. Sometimes however you may want to go more classes up than one. In this case you could try the @at-root and #{} css features which would enable two root classes to sit next to each other using &.

This wouldn't work (due to the nothing before & rule):

container {_x000D_
    background:red;_x000D_
    color:white;_x000D_
    _x000D_
    .desc& {_x000D_
      background: blue;_x000D_
    }_x000D_
_x000D_
    .hello {_x000D_
        padding-left:50px;_x000D_
    }_x000D_
}

But this would (using @at-root plus #{&}):

container {_x000D_
    background:red;_x000D_
    color:white;_x000D_
    _x000D_
    @at-root .desc#{&} {_x000D_
      background: blue;_x000D_
    }_x000D_
_x000D_
    .hello {_x000D_
        padding-left:50px;_x000D_
    }_x000D_
}

I needed to get the element as a string.

jQuery("#bob").get(0).outerHTML;

Which will give you something like:

<input type="text" id="bob" value="hello world" />

...as a string rather than a DOM element.

There is also %s that allows you to create any symbols, for example:

%s|some words|          #Same as :'some words'
%s[other words]         #Same as :'other words'
%s_last example_        #Same as :'last example'

Since Ruby 2.0.0 you also have:

%i( a b c )   # => [ :a, :b, :c ]
%i[ a b c ]   # => [ :a, :b, :c ]
%i_ a b c _   # => [ :a, :b, :c ]
# etc...

The SQL Server Management Studio has implicit commit turned on, so all statements that are executed are implicitly commited.

This might be a scary thing if you come from an Oracle background where the default is to not have commands commited automatically, but it's not that much of a problem.

If you still want to use ad-hoc transactions, you can always execute

BEGIN TRANSACTION

within SSMS, and than the system waits for you to commit the data.

If you want to replicate the Oracle behaviour, and start an implicit transaction, whenever some DML/DDL is issued, you can set the SET IMPLICIT_TRANSACTIONS checkbox in

Tools -> Options -> Query Execution -> SQL Server -> ANSI

def f(dic):
    if 'a' in dic:
        print dic['a'],
        pass
    else: print 'None',

    if 'b' in dic:
        print dic['b'],
        pass
    else: print 'None',

    if 'c' in dic:
        print dic['c'],
        pass
    else: print 'None',
    print
    pass
f({})
f({'a':20,
   'c':30})
f({'a':20,
   'c':30,
   'b':'red'})
____________

the above code will output

None None None
20 None 30
20 red 30

This is as good as passing variable arguments by means of a dictionary

This is more of an xpath question, but like this, assuming the context is the parent element:

<xsl:value-of select="name/@attribute1" />

It looks like you can download just the grid now on Bootstrap 4s new download features.

The new cv2 interface for Python integrates numpy arrays into the OpenCV framework, which makes operations much simpler as they are represented with simple multidimensional arrays. For example, your question would be answered with:

import cv2  # Not actually necessary if you just want to create an image.
import numpy as np
blank_image = np.zeros((height,width,3), np.uint8)

This initialises an RGB-image that is just black. Now, for example, if you wanted to set the left half of the image to blue and the right half to green , you could do so easily:

blank_image[:,0:width//2] = (255,0,0)      # (B, G, R)
blank_image[:,width//2:width] = (0,255,0)

If you want to save yourself a lot of trouble in future, as well as having to ask questions such as this one, I would strongly recommend using the cv2 interface rather than the older cv one. I made the change recently and have never looked back. You can read more about cv2 at the OpenCV Change Logs.

In the initialization use:

"fnServerData": function ( sSource, aoData, fnCallback ) {
                    //* Add some extra data to the sender *
                    newData = aoData;
                    newData.push({ "name": "key", "value": $('#value').val() });

                    $.getJSON( sSource, newData, function (json) {
                        //* Do whatever additional processing you want on the callback, then tell DataTables *
                        fnCallback(json);
                    } );
                },

And then just use:

$("#table_id").dataTable().fnDraw();

The important thing in the fnServerData is:

    newData = aoData;
    newData.push({ "name": "key", "value": $('#value').val() });

if you push directly to aoData, the change is permanent the first time you draw the table and fnDraw don't work the way you want.

Be sure to have a stylesheet assigned for printing.
It could be a separate stylesheet:

<link rel="stylesheet" type="text/css" media="print" href="print.css">

or one you share for all devices:

<link rel="stylesheet" type="text/css" href="bootstrap.min.css"> # Note there's no media attribute

Then, you can write your styles for printers in the separate stylesheets or in the shared one using media queries:

@media print {
    /* Your styles here */
}

Another way is to use only a '-' in the argument for argsort as in : "df[np.argsort(-df[:, 0])]", provided df is the dataframe and you want to sort it by the first column (represented by the column number '0'). Change the column-name as appropriate. Of course, the column has to be a numeric one.

If istream fails to insert, it will set the fail bit.

int i = 0;
std::cin >> i; // type a and press enter
if (std::cin.fail())
{
    std::cout << "I failed, try again ..." << std::endl
    std::cin.clear(); // reset the failed state
}

You can set this up in a do-while loop to get the correct type (int in this case) propertly inserted.

For more information: http://augustcouncil.com/~tgibson/tutorial/iotips.html#directly

You'd need to use return values.

DECLARE @SelectedValue int

CREATE PROCEDURE GetMyInt (@MyIntField int OUTPUT)
AS
SELECT @MyIntField = MyIntField FROM MyTable WHERE MyPrimaryKeyField = 1

Then you call it like this:

EXEC GetMyInt OUTPUT @SelectedValue

Don't know whether this is useful but if you want to work with multiple projects without navigating through projects tree {like multi window} you can try opening VS in another virtual desktop (at least it's possible for Windows 10) by holding Ctrl+win+D. Then open another VS studio and open your other project there. You can switch between projects by Ctrl+win+arrow key {left/right}.

Try the following, I put it together using Update 2 from another answer with high votes, and it worked perfectly for me:

br
{   content: "A" !important;
    display: block !important;
    margin-bottom: 1.5em !important;
}

You can check the android VLC it can stream and play video, if you want to indagate more, you can check their GIT to analyze what their do. Good luck!

For people just stumbling upon this now, I resolved an error of this type that was thrown with all the references and using statements placed properly. There's evidently some confusion with substituting in a function that returns DataTable instead of calling it on a declared DataTable. For example:

This worked for me:

DataTable dt = SomeObject.ReturnsDataTable();

List<string> ls = dt.AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

But this didn't:

List<string> ls = SomeObject.ReturnsDataTable().AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();

I'm still not 100% sure why, but if anyone is frustrated by an error of this type, give this a try.

def isPrime(x):
    if x<2:
        return False
    for i in range(2,x):
        if not x%i:

    return True  

print isPrime(2)
True
print isPrime(3)
True
print isPrime(9)
False

var filtered = projects;
foreach (var tag in filteredTags) {
  filtered = filtered.Where(p => p.Tags.Contains(tag))

The nice thing with this approach is that you can refine search results incrementally.

It's easier to use the timestamp for this things since Tweepy gets both

import datetime
print(datetime.datetime.fromtimestamp(int(t1)).strftime('%H:%M'))

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path. As mention below exePath mean folder where exe placed along with it's references files.

Exe application creating any temporaray file so it will create in folder mention in processBuilder.directory(...)

**

ProcessBuilder processBuilder = new ProcessBuilder(arguments);
processBuilder.redirectOutput(Redirect.PIPE);
processBuilder.directory(new File(exePath));
process = processBuilder.start();
int waitFlag = process.waitFor();// Wait to finish application execution.
if (waitFlag == 0) {
...
 int returnVal = process.exitValue();
}

On Samsung go to "Settings" -> "Lock screen and security" -> "Other security settings" -> "Phone administrators" and deselect the admin which you want to uninstall.

The "security" word was hidden on my display, so it was not obvious that I should click on "Lock screen".

According to the API for XCUIElement .exists can be used to check if a query exists or not so the following syntax could be useful in some cases!

let app = XCUIApplication()
app.launch()

let label = app.staticTexts["Hello, world!"]
while !label.exists {
    sleep(1)
}

If you are confident that your expectation will be met eventually you could try running this. It should be noted that crashing might be preferable if the wait is too long in which case waitForExpectationsWithTimeout(_,handler:_) from @Joe Masilotti's post should be used.

You can use the Source property of the image. Try this code...

ImageSource imageSource = new BitmapImage(new Uri("C:\\FileName.gif"));

image1.Source = imageSource;

It looks like you can simply do:

SELECT * FROM your_table WHERE some_column IS NULL OR some_column = '';

Test case:

CREATE TABLE your_table (id int, some_column varchar(10));

INSERT INTO your_table VALUES (1, NULL);
INSERT INTO your_table VALUES (2, '');
INSERT INTO your_table VALUES (3, 'test');
INSERT INTO your_table VALUES (4, 'another test');
INSERT INTO your_table VALUES (5, NULL);

Result:

SELECT id FROM your_table WHERE some_column IS NULL OR some_column = '';

id        
----------
1

jQuery('#main').css('opacity') = '0.6';

should be

jQuery('#main').css('opacity', '0.6');

Update:

http://jsfiddle.net/GegMk/ if you type in the text box. Click away, the opacity changes.

Change

var trainindIdArray = traingIds.split(',');

to

var trainindIdArray = traingIds.replace("[","").replace("]","").split(',');

That will basically remove [ and ] and then split the string

Because a scrollView can have other scrollViews or different inDepth subViews tree, run in depth recursively is preferable.

Swift 2

extension UIScrollView {
    //it will block the mainThread
    func recalculateVerticalContentSize_synchronous () {
        let unionCalculatedTotalRect = recursiveUnionInDepthFor(self)
        self.contentSize = CGRectMake(0, 0, self.frame.width, unionCalculatedTotalRect.height).size;
    }

    private func recursiveUnionInDepthFor (view: UIView) -> CGRect {
        var totalRect = CGRectZero
        //calculate recursevly for every subView
        for subView in view.subviews {
            totalRect =  CGRectUnion(totalRect, recursiveUnionInDepthFor(subView))
        }
        //return the totalCalculated for all in depth subViews.
        return CGRectUnion(totalRect, view.frame)
    }
}

Usage

scrollView.recalculateVerticalContentSize_synchronous()

This error can be seen for a number of reasons:

1. As mentioned above, starting the parenthesis on a new line.

Error:

render() {
  return  
  (
    <div>I am demo data</div>
  )
}

Correct way to implement render:

render() {
  return (
    <div>I am demo html</div>
  );
}

In the above example, the semicolon at the end of the return statement will not make any difference.

2. It can also be caused due to the wrong brackets used in the routing:

Error:

export default () => {
  <BrowserRouter>
    <Switch>
      <Route exact path='/' component={ DemoComponent } />
    </Switch>
  </BrowserRouter>
}

Correct way:

export default () => (
  <BrowserRouter>
    <Switch>
      <Route exact path='/' component={ DemoComponent } />
    </Switch>
  </BrowserRouter>
)

In the error example, we have used curly braces but we have to use round brackets instead. This also gives the same error.

• OPTIONS Identifying which HTTP methods a resource supports, e.g. can we DELETE it or update it via a PUT?
• HEAD Checking whether a resource has changed. This is useful when maintaining a cached version of a resource
• HEAD Retrieving metadata about the resource, e.g. its media type or its size, before making a possibly costly retrieval
• HEAD, OPTIONS Testing whether a resource exists and is accessible. For example, validating user-submitted links in an application

Here is nice and concise article about how HEAD and OPTIONS fit into RESTful architecture.

Just use this

$('#multipleSelect').change(function() {
    var selectedValues = $(this).val();  
});

As written before, but for beginner like me don't forget to include the return.

$this->response->statusCode(200);
return $this->response;

You can use DataFrame.fillna or Series.fillna which will replace the Python object None, not the string 'None'.

import pandas as pd
import numpy as np

For dataframe:

df = df.fillna(value=np.nan)

For column or series:

df.mycol.fillna(value=np.nan, inplace=True)

I made this code snippet to reflectively instantiate a class which is passed for a simple automated test utility.

Object attributeValue = null;
try {
    if(clazz.isArray()){
        Class<?> arrayType = clazz.getComponentType();
        attributeValue = Array.newInstance(arrayType, 0);
    }
    else if(!clazz.isInterface()){
        attributeValue = BeanUtils.instantiateClass(clazz);
    }
} catch (Exception e) {
    logger.debug("Cannot instanciate \"{}\"", new Object[]{clazz});
}

Note this segment:

    if(clazz.isArray()){
        Class<?> arrayType = clazz.getComponentType();
        attributeValue = Array.newInstance(arrayType, 0);
    }

for array initiating where Array.newInstance(class of array, size of array). Class can be both primitive (int.class) and object (Integer.class).

BeanUtils is part of Spring.

Change the Target version to new updates you have. Otherwise, change what SDK version you have in the Android manifest file.

android:minSdkVersion="8"
android:targetSdkVersion="18"

Ok, I think I was able to find a proper solution for that.

Now, instead of sending <Link/> as prop to Document, I send <NextLink/> which is a custom wrapper for the react-router Link. By doing that, I'm able to have the right arrow as part of the Link structure while still avoiding to have routing code inside Document object.

The updated code looks like follows:

//in NextLink.js
var React = require('react');
var Right = require('./Right');

var NextLink = React.createClass({
    propTypes: {
        link: React.PropTypes.node.isRequired
    },

    contextTypes: {
        transitionTo: React.PropTypes.func.isRequired
    },

    _onClickRight: function() {
        this.context.transitionTo(this.props.link.props.to);
    },

    render: function() {
        return (
            <div>
                {this.props.link}
                <Right onClick={this._onClickRight} />
            </div>  
        );
    }
});

module.exports = NextLink;

...
//in MasterPage.js
var sampleLink = <Link to="/sample">Go To Sample</Link>
var nextLink = <NextLink link={sampleLink} />
<Document next={nextLink} />

//in Document.js
...
var Document = React.createClass({
   render: function() {
      return (
         ...
         <div>{this.props.next}</div>
         ...
      );
   }
});
...

P.S: If you are using the latest version of react-router you may need to use this.context.router.transitionTo instead of this.context.transitionTo. This code will work fine for react-router version 0.12.X.

This is not a design flaw. Anyone who trips over this is doing something wrong.

There are 3 cases I see where you might run into this problem:

1. You intend to modify the argument as a side effect of the function. In this case it never makes sense to have a default argument. The only exception is when you're abusing the argument list to have function attributes, e.g. cache={}, and you wouldn't be expected to call the function with an actual argument at all.
2. You intend to leave the argument unmodified, but you accidentally did modify it. That's a bug, fix it.
3. You intend to modify the argument for use inside the function, but didn't expect the modification to be viewable outside of the function. In that case you need to make a copy of the argument, whether it was the default or not! Python is not a call-by-value language so it doesn't make the copy for you, you need to be explicit about it.

The example in the question could fall into category 1 or 3. It's odd that it both modifies the passed list and returns it; you should pick one or the other.

• The audio must be placed in the raw folder, if it doesn't exists, create one.
• The raw folder must be inside the res folder
• The name mustn't have any - or special characters in it.

On your activity, you need to have a object MediaPlayer, inside the onCreate method or the onclick method, you have to initialize the MediaPlayer, like MediaPlayer.create(this, R.raw.name_of_your_audio_file), then your audio file ir ready to be played with the call for start(), in your case, since you want it to be placed in a button, you'll have to put it inside the onClick method.

Example:

private Button myButton;
private MediaPlayer mp;
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.myactivity);
        mp = MediaPlayer.create(this, R.raw.gunshot);

        myButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                mp.start();
            }
        });
}
}

If you type:

?sample

If will launch a help menu to explain what the parameters of the sample function mean.

I am not an expert, but here is some code I have:

data <- data.frame(matrix(rnorm(400), nrow=100))
splitdata <- split(data[1:nrow(data),],sample(rep(1:4,as.integer(nrow(data)/4))))
test <- splitdata[[1]]
train <- rbind(splitdata[[1]],splitdata[[2]],splitdata[[3]])

This will give you 75% train and 25% test.

1. Download and add imgscalr-lib-x.x.jar and imgscalr-lib-x.x-javadoc.jar to your Projects Libraries.

2. In your code:

   import static org.imgscalr.Scalr.*;
   
   public static BufferedImage resizeBufferedImage(BufferedImage image, Scalr.Method scalrMethod, Scalr.Mode scalrMode, int width, int height)  {
       BufferedImage bi = image;
       bi = resize( image, scalrMethod, scalrMode, width, height);
   return bi;
   }
   
   // Save image:
   ImageIO.write(Scalr.resize(etotBImage, 150), "jpg", new File(myDir));
   

Winand, Quality was also an issue for me so I did this:

For Each ws In ActiveWorkbook.Worksheets
    If ws.PageSetup.PrintArea <> "" Then
        'Reverse the effects of page zoom on the exported image
        zoom_coef = 100 / ws.Parent.Windows(1).Zoom
        areas = Split(ws.PageSetup.PrintArea, ",")
        areaNo = 0
        For Each a In areas
            Set area = ws.Range(a)
            ' Change xlPrinter to xlScreen to see zooming white space
            area.CopyPicture Appearance:=xlPrinter, Format:=xlPicture
            Set chartobj = ws.ChartObjects.Add(0, 0, area.Width * zoom_coef, area.Height * zoom_coef)
            chartobj.Chart.Paste
            'scale the image before export
            ws.Shapes(chartobj.Index).ScaleHeight 3, msoFalse, msoScaleFromTopLeft
            ws.Shapes(chartobj.Index).ScaleWidth 3, msoFalse, msoScaleFromTopLeft
            chartobj.Chart.Export ws.Name & "-" & areaNo & ".png", "png"
            chartobj.delete
            areaNo = areaNo + 1
        Next
    End If
Next

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

I have several version of JDK (not JRE) instaled and I launch Eclipse with:

C:\eclipse\eclipse.exe -vm "%JAVA_HOME%\bin\javaw.exe" -data f:\dev\java\2013

As you can see, I set JAVA_HOME to point to the version of JDK I want to use.

I NEVER add javaw.exe in the PATH.

You can use the npm modules jsdom and htmlparser to create and parse a DOM in Node.JS.

Other options include:

• BeautifulSoup for python
• you can convert you html to xhtml and use XSLT
• HTMLAgilityPack for .NET
• CsQuery for .NET (my new favorite)
• The spidermonkey and rhino JS engines have native E4X support. This may be useful, only if you convert your html to xhtml.

Out of all these options, I prefer using the Node.js option, because it uses the standard W3C DOM accessor methods and I can reuse code on both the client and server. I wish BeautifulSoup's methods were more similar to the W3C dom, and I think converting your HTML to XHTML to write XSLT is just plain sadistic.

This checks the ENTIRE string, not just the first letter. I thought I'd share it with everyone here.

Here is a function that uses a regular expression to test against the letters of a string; it returns true if the letter is uppercase (A-Z). We then reduce the true/false array to a single value. If it is equal to the length of the string, that means all the letters passed the regex test, which means the string is uppercase. If not, the string is lowercase.

const isUpperCase = (str) => {
  let result = str
    .split('')
    .map(letter => /[A-Z]/.test(letter))
    .reduce((a, b) => a + b);

  return result === str.length;
}

console.log(isUpperCase('123')); // false
console.log('123' === '123'.toUpperCase()); // true

A 302 status code is HTTP response status code indicating that the requested resource has been temporarily moved to a different URI. Since the location or current redirection directive might be changed in the future, a client that receives a 302 Found response code should continue to use the original URI for future requests.

An HTTP response with this status code will additionally provide a URL in the header field Location. This is an invitation to the user agent (e.g. a web browser) to make a second, otherwise identical, request to the new URL specified in the location field. The end result is a redirection to the new URL.

Just as a future reference, if you already have a Maven project all you need to do is doing a gradle init in your project directory which will generates build.gradle and other dependencies, then do a gradle build in the same directory.

You cannot use Set Transaction Isolation Level Read Uncommitted in a View (you can only have one script in there in fact), so you would have to use (nolock) if dirty rows should be included.

To also highlight the menu item when one of the child pages is active, also check for the other class (current-page-ancestor) like below:

add_filter('nav_menu_css_class' , 'special_nav_class' , 10 , 2);

function special_nav_class ($classes, $item) {
    if (in_array('current-page-ancestor', $classes) || in_array('current-menu-item', $classes) ){
        $classes[] = 'active ';
    }
    return $classes;
}

OK, I landed here because I recently came across the same issue when checking the classic stack implementation. Just a reminder that this is used in the array based implementation of Stack, which is a bit faster than the linked-list one.

Code below, check the push and pop func.

public class FixedCapacityStackOfStrings
{
  private String[] s;
  private int N=0;

  public FixedCapacityStackOfStrings(int capacity)
  { s = new String[capacity];}

  public boolean isEmpty()
  { return N == 0;}

  public void push(String item)
  { s[N++] = item; }

  public String pop()
  { 
    String item = s[--N];
    s[N] = null;
    return item;
  }
}

I think you want to speed up your cell loading at the time of image loading for cell in the background. For that we have done the following steps:

1. Checking the file exists in the document directory or not.

2. If not then loading the image for the first time, and saving it to our phone document directory. If you don't want to save the image in the phone then you can load cell images directlyin the background.

3. Now the loading process:

Just include: #import "ManabImageOperations.h"

The code is like below for a cell:

NSString *imagestr=[NSString stringWithFormat:@"http://www.yourlink.com/%@",[dictn objectForKey:@"member_image"]];

        NSString *docDir=[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
        NSLog(@"Doc Dir: %@",docDir);

        NSString  *pngFilePath = [NSString stringWithFormat:@"%@/%@",docDir,[dictn objectForKey:@"member_image"]];

        BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:pngFilePath];
        if (fileExists)
        {
            [cell1.memberimage setImage:[UIImage imageWithContentsOfFile:pngFilePath] forState:UIControlStateNormal];
        }
        else
        {
            [ManabImageOperations processImageDataWithURLString:imagestr andBlock:^(NSData *imageData)
             {
                 [cell1.memberimage setImage:[[UIImage alloc]initWithData: imageData] forState:UIControlStateNormal];
                [imageData writeToFile:pngFilePath atomically:YES];
             }];
}

ManabImageOperations.h:

#import <Foundation/Foundation.h>

    @interface ManabImageOperations : NSObject
    {
    }
    + (void)processImageDataWithURLString:(NSString *)urlString andBlock:(void (^)(NSData *imageData))processImage;
    @end

ManabImageOperations.m:

#import "ManabImageOperations.h"
#import <QuartzCore/QuartzCore.h>
@implementation ManabImageOperations

+ (void)processImageDataWithURLString:(NSString *)urlString andBlock:(void (^)(NSData *imageData))processImage
{
    NSURL *url = [NSURL URLWithString:urlString];

    dispatch_queue_t callerQueue = dispatch_get_main_queue();
    dispatch_queue_t downloadQueue = dispatch_queue_create("com.myapp.processsmagequeue", NULL);
    dispatch_async(downloadQueue, ^{
        NSData * imageData = [NSData dataWithContentsOfURL:url];

        dispatch_async(callerQueue, ^{
            processImage(imageData);
        });
    });
  //  downloadQueue=nil;
    dispatch_release(downloadQueue);

}
@end

If you only want to import a certificate in PEM format into a keystore, keytool will do the job:

Lambdas are actually very powerful constructs that stem from ideas in functional programming, and it is something that by no means will be easily revised, redefined or removed in the near future of Python. They help you write code that is more powerful as it allows you to pass functions as parameters, thus the idea of functions as first-class citizens.

Lambdas do tend to get confusing, but once a solid understanding is obtained, you can write clean elegant code like this:

squared = map(lambda x: x*x, [1, 2, 3, 4, 5])

The above line of code returns a list of the squares of the numbers in the list. Ofcourse, you could also do it like:

def square(x):
    return x*x

squared = map(square, [1, 2, 3, 4, 5])

It is obvious the former code is shorter, and this is especially true if you intend to use the map function (or any similar function that takes a function as a parameter) in only one place. This also makes the code more intuitive and elegant.

Also, as @David Zaslavsky mentioned in his answer, list comprehensions are not always the way to go especially if your list has to get values from some obscure mathematical way.

From a more practical standpoint, one of the biggest advantages of lambdas for me recently has been in GUI and event-driven programming. If you take a look at callbacks in Tkinter, all they take as arguments are the event that triggered them. E.g.

def define_bindings(widget):
    widget.bind("<Button-1>", do-something-cool)

def do-something-cool(event):
    #Your code to execute on the event trigger

Now what if you had some arguments to pass? Something as simple as passing 2 arguments to store the coordinates of a mouse-click. You can easily do it like this:

def main():
    # define widgets and other imp stuff
    x, y = None, None
    widget.bind("<Button-1>", lambda event: do-something-cool(x, y))

def do-something-cool(event, x, y):
    x = event.x
    y = event.y
    #Do other cool stuff

Now you can argue that this can be done using global variables, but do you really want to bang your head worrying about memory management and leakage especially if the global variable will just be used in one particular place? That would be just poor programming style.

In short, lambdas are awesome and should never be underestimated. Python lambdas are not the same as LISP lambdas though (which are more powerful), but you can really do a lot of magical stuff with them.

Try this. It works for me.

/*url.php file*/

trait URL {
    private $url = '';
    private $current_url = '';
    public $get = '';

    function __construct()
    {
        $this->url = $_SERVER['SERVER_NAME'];
        $this->current_url = $_SERVER['REQUEST_URI'];

        $clean_server = str_replace('', $this->url, $this->current_url);
        $clean_server = explode('/', $clean_server);

        $this->get = array('base_url' => "/".$clean_server[1]);
    }
}

Use like this:

<?php
/*

Tested for links:

http://localhost/index.php
http://localhost/
http://localhost/index.php/
http://localhost/url/index.php    
http://localhost/url/index.php/

*/

require_once 'sys/url.php';

class Home
{
    use URL;
}

$h = new Home();

?>

<a href="<?=$h->get['base_url']?>">Base</a>

All previous answers have since been deprecated. This method works as of Aug 2016:

To get the like count of any URL:

GET request: https://graph.facebook.com/[url]/access_token=[access_token]

Then grab shares->share_count from the returned JSON object.

Fan count for a Facebook page:

GET request: https://graph.facebook.com/[url]/?fields=fan_count&access_token=[access_token]

Then grab the 'fan_count' field from the returned JSON object.

You can test this out and get your access token using the Graph API Explorer

The following CSS rule disables resizing behavior for textarea elements:

textarea {
  resize: none;
}

To disable it for some (but not all) textareas, there are a couple of options.

To disable a specific textarea with the name attribute set to foo (i.e., <textarea name="foo"></textarea>):

textarea[name=foo] {
  resize: none;
}

Or, using an id attribute (i.e., <textarea id="foo"></textarea>):

#foo {
  resize: none;
}

The W3C page lists possible values for resizing restrictions: none, both, horizontal, vertical, and inherit:

textarea {
  resize: vertical; /* user can resize vertically, but width is fixed */
}

Review a decent compatibility page to see what browsers currently support this feature. As Jon Hulka has commented, the dimensions can be further restrained in CSS using max-width, max-height, min-width, and min-height.

Super important to know:

This property does nothing unless the overflow property is something other than visible, which is the default for most elements. So generally to use this, you'll have to set something like overflow: scroll;

This is little more explanation for pass by value and pass by reference (JavaScript). In this concept, they are talking about passing the variable by reference and passing the variable by reference.

Pass by value (primitive type)

var a = 3;
var b = a;

console.log(a); // a = 3
console.log(b); // b = 3

a=4;
console.log(a); // a = 4
console.log(b); // b = 3

• applies to all primitive type in JavaScript (string, number, Boolean, undefined, and null).
• a is allocated a memory (say 0x001) and b creates a copy of the value in memory (say 0x002).
• So changing the value of a variable doesn't affect the other, as they both reside in two different locations.

Pass by reference (objects)

var c = { "name" : "john" };
var d = c;

console.log(c); // { "name" : "john" }
console.log(d); // { "name" : "john" }

c.name = "doe";

console.log(c); // { "name" : "doe" }
console.log(d); // { "name" : "doe" }

• The JavaScript engine assigns the object to the variable c, and it points to some memory, say (0x012).
• When d=c, in this step d points to the same location (0x012).
• Changing the value of any changes value for both the variable.
• Functions are objects

Special case, pass by reference (objects)

c = {"name" : "jane"};
console.log(c); // { "name" : "jane" }
console.log(d); // { "name" : "doe" }

• The equal(=) operator sets up new memory space or address

Not that I know of, but what you could do is loop through the first 31 lines doing nothing using the readline() function of BufferedReader

FileInputStream fs= new FileInputStream("someFile.txt");
BufferedReader br = new BufferedReader(new InputStreamReader(fs));
for(int i = 0; i < 31; ++i)
  br.readLine();
String lineIWant = br.readLine();

Right Click on Project -> Build Path -> Configure Build Path. Check if Maven Dependencies is there in list, if not then update maven project by Right Click on Project -> Maven -> Update Project

I presume that this question is a continuation of this one.

What are you trying to do? Do you really want to dynamically change the text in your TextView objects when the user clicks a button? You can certainly do that, if you have a reason, but, if the text is static, it is usually set in the main.xml file, like this:

<TextView  
android:id="@+id/rate"
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/rate"
/>

The string "@string/rate" refers to an entry in your strings.xml file that looks like this:

<string name="rate">Rate</string>

If you really want to change this text later, you can do so by using Nikolay's example - you'd get a reference to the TextView by utilizing the id defined for it within main.xml, like this:

final TextView textViewToChange = (TextView) findViewById(R.id.rate);
textViewToChange.setText(
    "The new text that I'd like to display now that the user has pushed a button.");

I would style a link to look like a button, because that way there is a no-js fallback.

So this is how you could animate the jump using jquery. No-js fallback is a normal jump without animation.

Original example:

jsfiddle

$(document).ready(function() {_x000D_
  $(".jumper").on("click", function( e ) {_x000D_
_x000D_
    e.preventDefault();_x000D_

New example with actual button styles for the links, just to prove a point.

Everything is essentially the same, except that I changed the class .jumper to .button and I added css styling to make the links look like buttons.

Button styles example

you can use webview to show the pdf inside an application , for that you have to :

1. convert the pdf to html file and store it in asset folder
2. load the html file to the web view ,

Many pdf to html online converter available.

Example:

    consent_web = (WebView) findViewById(R.id.consentweb);
    consent_web.getSettings().setLoadWithOverviewMode(true);
    consent_web.getSettings().setUseWideViewPort(true);
    consent_web.loadUrl("file:///android_asset/spacs_html.html");

In newer hibernate jars, you can find the required jpa file under "hibernate-search-5.8.0.Final\dist\lib\provided\hibernate-jpa-2.1-api-1.0.0.Final". You have to add this jar file into your project java build path. This will most probably solve the issue.

If you don't want to use SSH, you could add the username and password in the HTTPS URL.

The code below assumes that you have a file called "pass" in the working directory that contains your password.

export PASS=$(cat pass)
pip install git+https://<username>:[email protected]/echweb/echweb-utils.git

OpenJPA allows you to specify non-standard annotation to define index on property.

Details are here.

Normal rounding will work with a small tweak:

Math.round(price * 10)/10

and if you want to keep a currency format, you can use the Number method .toFixed()

(Math.round(price * 10)/10).toFixed(2)

Though this will make it a String =)

I was trying to to the same, I found lots of information on reading .docx but much less on .doc; Anyway, I managed to read the text using the following:

import win32com.client

word = win32com.client.Dispatch("Word.Application")
word.visible = False
wb = word.Documents.Open("myfile.doc")
doc = word.ActiveDocument
print(doc.Range().Text)

if you continue to have problems with the native driver, you can also check out sleepy mongoose. It's a python REST server that you can simply access with node request to get to your Mongo instance. http://www.snailinaturtleneck.com/blog/2010/02/22/sleepy-mongoose-a-mongodb-rest-interface/

As string[] implements IEnumerable

IEnumerable<string> m_oEnum = new string[] {"1","2","3"}

I had a situation where i was working with a custom component and i needed to clear the form data.

But only if the page was in 'create' form state, and if the page was not being used to edit an existing item. So I made a method.

I called this method inside a watcher on custom component file, and not the vue page that uses the custom component. If that makes sense.

The entire form $ref was only available to me on the Base Custom Component.

<!-- Custom component HTML -->
<template>
  <v-form ref="form" v-model="valid" @submit.prevent>
    <slot v-bind="{ formItem, formState, valid }"></slot>
  </v-form>
</template>

watch: {
  value() {
    // Some other code here
    this.clearFormDataIfNotEdit(this)
    // Some other code here too
  }
}
... some other stuff ....

methods: {
  clearFormDataIfNotEdit(objct) {
    if (objct.formstate === 'create' && objct.formItem.id === undefined) {
       objct.$refs.form.reset()
    }
  },
}

Basically i checked to see if the form data had an ID, if it did not, and the state was on create, then call the obj.$ref.form.reset() if i did this directly in the watcher, then it would be this.$ref.form.reset() obvs.

But you can only call the $ref from the page which it's referenced. Which is what i wanted to call out with this answer.

Furthermore, if in the same Jenkins project we need to checkout several private GitHub repositories into several separate dirs under a project root. How can we do it please?

The Jenkin's Multiple SCMs Plugin has solved the several repositories problem for me very nicely. I have just got working a project build that checks out four different git repos under a common folder. (I'm a bit reluctant to use git super-projects as suggested previously by Lukasz Rzanek, as git is complex enough without submodules.)
