First, install unzip on colab:

!apt install unzip

then use unzip to extract your files:

!unzip  source.zip -d destination.zip

Another option is:

$string = $assoc.ID
$string += " - "
$string += $assoc.Name
$string += " - "
$string += $assoc.Owner
Write-Host $string

The "best" method is probably the one C.B. suggested:

Write-Host "$($assoc.Id)  -  $($assoc.Name)  -  $($assoc.Owner)"

Here are some guideline steps...

1. Create a borderless form (this will be your splash screen)
2. On application start, start a timer (with a few seconds interval)
3. Show your Splash Form
4. On Timer.Tick event, stop timer and close Splash form - then show your main application form

Give this a go and if you get stuck then come back and ask more specific questions relating to your problems

You can use System.load() to provide an absolute path which is what you want, rather than a file in the standard library folder for the respective OS.

If you want native applications that already exist, use System.loadLibrary(String filename). If you want to provide your own you're probably better with load().

You should also be able to use loadLibrary with the java.library.path set correctly. See ClassLoader.java for implementation source showing both paths being checked (OpenJDK)

UPDATE: DELETE from a trigger works on both MSSql 7 and MSSql 2008.

I'm no relational guru, nor a SQL standards wonk. However - contrary to the accepted answer - MSSQL deals just fine with both recursive and nested trigger evaluation. I don't know about other RDBMSs.

The relevant options are 'recursive triggers' and 'nested triggers'. Nested triggers are limited to 32 levels, and default to 1. Recursive triggers are off by default, and there's no talk of a limit - but frankly, I've never turned them on, so I don't know what happens with the inevitable stack overflow. I suspect MSSQL would just kill your spid (or there is a recursive limit).

Of course, that just shows that the accepted answer has the wrong reason, not that it's incorrect. However, prior to INSTEAD OF triggers, I recall writing ON INSERT triggers that would merrily UPDATE the just inserted rows. This all worked fine, and as expected.

A quick test of DELETEing the just inserted row also works:

 CREATE TABLE Test ( Id int IDENTITY(1,1), Column1 varchar(10) )
 GO

 CREATE TRIGGER trTest ON Test 
 FOR INSERT 
 AS
    SET NOCOUNT ON
    DELETE FROM Test WHERE Column1 = 'ABCDEF'
 GO

 INSERT INTO Test (Column1) VALUES ('ABCDEF')
 --SCOPE_IDENTITY() should be the same, but doesn't exist in SQL 7
 PRINT @@IDENTITY --Will print 1. Run it again, and it'll print 2, 3, etc.
 GO

 SELECT * FROM Test --No rows
 GO

You have something else going on here.

boolean found;

for(CustomObject obj : ArrayOfCustObj) {

   if(obj.getName.equals("Android")) {

      found = true;
   }
}

You can do this by using the following xml

<RelativeLayout
    style="@style/GenericProgressBackground"
    android:id="@+id/loadingPanel"
    >
    <ProgressBar
        style="@style/GenericProgressIndicator"/>
</RelativeLayout>

With this style

<style name="GenericProgressBackground" parent="android:Theme">
    <item name="android:layout_width">fill_parent</item>    
    <item name="android:layout_height">fill_parent</item>
    <item name="android:background">#DD111111</item>    
    <item name="android:gravity">center</item>  
</style>
<style name="GenericProgressIndicator" parent="@android:style/Widget.ProgressBar.Small">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:indeterminate">true</item> 
</style>

To use this, you must hide your UI elements by setting the visibility value to GONE and whenever the data is loaded, call setVisibility(View.VISIBLE) on all your views to restore them. Don't forget to call findViewById(R.id.loadingPanel).setVisiblity(View.GONE) to hide the loading animation.

If you dont have a loading event/function but just want the loading panel to disappear after x seconds use a Handle to trigger the hiding/showing.

There is no implicit style that you have to choose, it involves writing a bit of code using the QuartzCore framework:

//first, you
#import <QuartzCore/QuartzCore.h>

//.....

//Here I add a UITextView in code, it will work if it's added in IB too
UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(50, 220, 200, 100)];

//To make the border look very close to a UITextField
[textView.layer setBorderColor:[[[UIColor grayColor] colorWithAlphaComponent:0.5] CGColor]];
[textView.layer setBorderWidth:2.0];

//The rounded corner part, where you specify your view's corner radius:
textView.layer.cornerRadius = 5;
textView.clipsToBounds = YES;

It only works on OS 3.0 and above, but I guess now it's the de facto platform anyway.

To pass variables from node.js to html by using the res.render() method.

Example:

var bodyParser = require('body-parser');
var express = require('express');
var app = express();

app.use(express.static(__dirname + '/'));
app.use(bodyParser.urlencoded({extend:true}));
app.engine('html', require('ejs').renderFile);
app.set('view engine', 'html');
app.set('views', __dirname);

app.get('/', function(req, res){
    res.render('index.html',{email:data.email,password:data.password});
});

You need antMatcher for multiple HttpSecurity, see Spring Security Reference:

5.7 Multiple HttpSecurity

We can configure multiple HttpSecurity instances just as we can have multiple <http> blocks. The key is to extend the WebSecurityConfigurationAdapter multiple times. For example, the following is an example of having a different configuration for URL’s that start with /api/.

@EnableWebSecurity
public class MultiHttpSecurityConfig {
  @Autowired
  public void configureGlobal(AuthenticationManagerBuilder auth) { 1
      auth
          .inMemoryAuthentication()
              .withUser("user").password("password").roles("USER").and()
              .withUser("admin").password("password").roles("USER", "ADMIN");
  }

  @Configuration
  @Order(1)                                                        2
  public static class ApiWebSecurityConfigurationAdapter extends WebSecurityConfigurerAdapter {
      protected void configure(HttpSecurity http) throws Exception {
          http
              .antMatcher("/api/**")                               3
              .authorizeRequests()
                  .anyRequest().hasRole("ADMIN")
                  .and()
              .httpBasic();
      }
  }    

  @Configuration                                                   4
  public static class FormLoginWebSecurityConfigurerAdapter extends WebSecurityConfigurerAdapter {

      @Override
      protected void configure(HttpSecurity http) throws Exception {
          http
              .authorizeRequests()
                  .anyRequest().authenticated()
                  .and()
              .formLogin();
      }
  }
}

1 Configure Authentication as normal

2 Create an instance of WebSecurityConfigurerAdapter that contains @Order to specify which WebSecurityConfigurerAdapter should be considered first.

3 The http.antMatcher states that this HttpSecurity will only be applicable to URLs that start with /api/

4 Create another instance of WebSecurityConfigurerAdapter. If the URL does not start with /api/ this configuration will be used. This configuration is considered after ApiWebSecurityConfigurationAdapter since it has an @Order value after 1 (no @Order defaults to last).

In your case you need no antMatcher, because you have only one configuration. Your modified code:

http
    .authorizeRequests()
        .antMatchers("/high_level_url_A/sub_level_1").hasRole('USER')
        .antMatchers("/high_level_url_A/sub_level_2").hasRole('USER2')
        .somethingElse() // for /high_level_url_A/**
        .antMatchers("/high_level_url_A/**").authenticated()
        .antMatchers("/high_level_url_B/sub_level_1").permitAll()
        .antMatchers("/high_level_url_B/sub_level_2").hasRole('USER3')
        .somethingElse() // for /high_level_url_B/**
        .antMatchers("/high_level_url_B/**").authenticated()
        .anyRequest().permitAll()

I've found that this error is also generated if the document is empty. In this case it's also because there is no root element - but the error message "Extra content and the end of the document" is misleading in this situation.

it works for me !!

in mysql table

DATETIME

in entity:

private Date startDate;

in process:

objectEntity.setStartDate(new Date());

in preparedStatement:

pstm.setDate(9, new java.sql.Date(objEntity.getStartDate().getTime()));

The same way how an int can be positive or negative. There is no difference. Actually on many platforms unqualified char is signed.

The new C++11 style:

#include <algorithm>
#include <string>
#include <cctype>

/// Try to find in the Haystack the Needle - ignore case
bool findStringIC(const std::string & strHaystack, const std::string & strNeedle)
{
  auto it = std::search(
    strHaystack.begin(), strHaystack.end(),
    strNeedle.begin(),   strNeedle.end(),
    [](char ch1, char ch2) { return std::toupper(ch1) == std::toupper(ch2); }
  );
  return (it != strHaystack.end() );
}

Explanation of the std::search can be found on cplusplus.com.

you can use "dynamicObject.PropertyName.Value" to get value of dynamic property directly.

Example :

d.property11.Value

This misled me a bit - it should be setImageResource instead of setBackgroundResource :) !!

The following works fine :

ImageButton btn = (ImageButton)findViewById(R.id.imageButton1);       
 btn.setImageResource(R.drawable.actions_record);

while when using the setBackgroundResource the actual imagebutton's image stays while the background image is changed which leads to a ugly looking imageButton object

Thanks.

It's very simple for Python 3.x (docs).

import csv

with open('output_file_name', 'w', newline='', encoding='utf-8') as csv_file:
    writer = csv.writer(csv_file, delimiter=';')
    writer.writerow('my_utf8_string')

For Python 2.x, look here.

It's really easy. Try the code below,

<RelativeLayout
    android:id="@+id/second_RL"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/first_RL"
    android:background="@android:color/holo_blue_bright"
    android:gravity="center">

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button" />

</RelativeLayout>

Another way which could make sense for the given situation is

BigDecimal newBD = oldBD.setScale(2);

I just say this because in some cases when it comes to money going beyond 2 decimal places does not make sense. Taking this a step further, this could lead to

String displayString = oldBD.setScale(2).toPlainString();

but I merely wanted to highlight the setScale method (which can also take a second rounding mode argument to control how that last decimal place is handled. In some situations, Java forces you to specify this rounding method).

The below logic is the solution without modifying the original list

List<String> str1 = new ArrayList<String>();
str1.add("A");
str1.add("B");
str1.add("C");
str1.add("D");

List<String> str2 = new ArrayList<String>();
str2.add("D");
str2.add("E");

List<String> str3 = str1.stream()
                        .filter(item -> !str2.contains(item))
                        .collect(Collectors.toList());

str1 // ["A", "B", "C", "D"]
str2 // ["D", "E"]
str3 // ["A", "B", "C"]

Update 2016:

Google Chrome released the storage API: http://developer.chrome.com/extensions/storage.html

It is pretty easy to use like the other Chrome APIs and you can use it from any page context within Chrome.

    // Save it using the Chrome extension storage API.
    chrome.storage.sync.set({'foo': 'hello', 'bar': 'hi'}, function() {
      console.log('Settings saved');
    });

    // Read it using the storage API
    chrome.storage.sync.get(['foo', 'bar'], function(items) {
      message('Settings retrieved', items);
    });

To use it, make sure you define it in the manifest:

    "permissions": [
      "storage"
    ],

There are methods to "remove", "clear", "getBytesInUse", and an event listener to listen for changed storage "onChanged"

Using native localStorage (old reply from 2011)

Content scripts run in the context of webpages, not extension pages. Therefore, if you're accessing localStorage from your contentscript, it will be the storage from that webpage, not the extension page storage.

Now, to let your content script to read your extension storage (where you set them from your options page), you need to use extension message passing.

The first thing you do is tell your content script to send a request to your extension to fetch some data, and that data can be your extension localStorage:

contentscript.js

chrome.runtime.sendMessage({method: "getStatus"}, function(response) {
  console.log(response.status);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getStatus")
      sendResponse({status: localStorage['status']});
    else
      sendResponse({}); // snub them.
});

You can do an API around that to get generic localStorage data to your content script, or perhaps, get the whole localStorage array.

I hope that helped solve your problem.

To be fancy and generic ...

contentscript.js

chrome.runtime.sendMessage({method: "getLocalStorage", key: "status"}, function(response) {
  console.log(response.data);
});

background.js

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
    if (request.method == "getLocalStorage")
      sendResponse({data: localStorage[request.key]});
    else
      sendResponse({}); // snub them.
});

You can use the before or after pseudo-element and apply some CSS to it. There are various ways. You can add both before and after, and rotate and position each of them to form one of the bars. An easier solution is adding two borders to just the before element and rotate it using transform: rotate.

Scroll down for a different solution that uses an actual element instead of the pseuso elements

In this case, I've added the arrows as bullets in a list and used em sizes to make them size properly with the font of the list.

ul {_x000D_
    list-style: none;_x000D_
}_x000D_
_x000D_
ul.big {_x000D_
    list-style: none;_x000D_
    font-size: 300%_x000D_
}_x000D_
_x000D_
li::before {_x000D_
    position: relative;_x000D_
    /* top: 3pt; Uncomment this to lower the icons as requested in comments*/_x000D_
    content: "";_x000D_
    display: inline-block;_x000D_
    /* By using an em scale, the arrows will size with the font */_x000D_
    width: 0.4em;_x000D_
    height: 0.4em;_x000D_
    border-right: 0.2em solid black;_x000D_
    border-top: 0.2em solid black;_x000D_
    transform: rotate(45deg);_x000D_
    margin-right: 0.5em;_x000D_
}_x000D_
_x000D_
/* Change color */_x000D_
li:hover {_x000D_
  color: red; /* For the text */_x000D_
}_x000D_
li:hover::before {_x000D_
  border-color: red; /* For the arrow (which is a border) */_x000D_
}

<ul>_x000D_
    <li>Item1</li>_x000D_
    <li>Item2</li>_x000D_
    <li>Item3</li>_x000D_
    <li>Item4</li>_x000D_
</ul>_x000D_
_x000D_
<ul class="big">_x000D_
    <li>Item1</li>_x000D_
    <li>Item2</li>_x000D_
    <li>Item3</li>_x000D_
    <li>Item4</li>_x000D_
</ul>

Of course you don't need to use before or after, you can apply the same trick to a normal element as well. For the list above it is convenient, because you don't need additional markup. But sometimes you may want (or need) the markup anyway. You can use a div or span for that, and I've even seen people even recycle the i element for 'icons'. So that markup could look like below. Whether using <i> for this is right is debatable, but you can use span for this as well to be on the safe side.

/* Default icon formatting */_x000D_
i {_x000D_
  display: inline-block;_x000D_
  font-style: normal;_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
/* Additional formatting for arrow icon */_x000D_
i.arrow {_x000D_
    /* top: 2pt; Uncomment this to lower the icons as requested in comments*/_x000D_
    width: 0.4em;_x000D_
    height: 0.4em;_x000D_
    border-right: 0.2em solid black;_x000D_
    border-top: 0.2em solid black;_x000D_
    transform: rotate(45deg);_x000D_
}

And so you can have an <i class="arrow" title="arrow icon"></i> in your text._x000D_
This arrow is <i class="arrow" title="arrow icon"></i> used to be deliberately lowered slightly on request._x000D_
I removed that for the general public <i class="arrow" title="arrow icon"></i> but you can uncomment the line with 'top' <i class="arrow" title="arrow icon"></i> to restore that effect.

If you seek more inspiration, make sure to check out this awesome library of pure CSS icons by Nicolas Gallagher. :)

[update] -- Well, my own foolishness provides the answer to this one. As it turns out, I was deleting the records from myTable before running the select COUNT statement.

How did I do that and not notice? Glad you asked. I've been testing a sql unit testing platform (tsqlunit, if you're interested) and as part of one of the tests I ran a truncate table statement, then the above. After the unit test is over everything is rolled back, and records are back in myTable. That's why I got a record count outside of my tests.

Sorry everyone...thanks for your help.

This issue arise because we try to delete the parent table still child table data is present. We solve the problem with help of cascade delete.

In model Create method in dbcontext class.

 modelBuilder.Entity<Job>()
                .HasMany<JobSportsMapping>(C => C.JobSportsMappings)
                .WithRequired(C => C.Job)
                .HasForeignKey(C => C.JobId).WillCascadeOnDelete(true);
            modelBuilder.Entity<Sport>()
                .HasMany<JobSportsMapping>(C => C.JobSportsMappings)
                  .WithRequired(C => C.Sport)
                  .HasForeignKey(C => C.SportId).WillCascadeOnDelete(true);

After that,In our API Call

var JobList = Context.Job                       
          .Include(x => x.JobSportsMappings)                                     .ToList();
Context.Job.RemoveRange(JobList);
Context.SaveChanges();

Cascade delete option delete the parent as well parent related child table with this simple code. Make it try in this simple way.

Remove Range which used for delete the list of records in the database Thanks

Best one

String str_date=month+"-"+day+"-"+yr;
DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy");
Date date = (Date)formatter.parse(str_date); 
long output=date.getTime()/1000L;
String str=Long.toString(output);
long timestamp = Long.parseLong(str) * 1000;

string data = "THExxQUICKxxBROWNxxFOX";

return data.Replace("xx","|").Split('|');

Just choose the replace character carefully (choose one that isn't likely to be present in the string already)!

i had problem to run it and i make some changes to run it with mp3 source. here is BackfrounSoundService.java file. consider that my mp3 file is in my sdcard in my phone .

public class BackgroundSoundService extends Service {
    private static final String TAG = null;
    MediaPlayer player;

    public IBinder onBind(Intent arg0) {

        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d("service", "onCreate");
        player = new MediaPlayer();
        try {
            player.setDataSource(Environment.getExternalStorageDirectory().getAbsolutePath() + "/your file.mp3");
        } catch (IOException e) {
            e.printStackTrace();
        }
        player.setLooping(true); // Set looping
        player.setVolume(100, 100);

    }

    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d("service", "onStartCommand");
        try {
            player.prepare();
            player.start();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return 1;
    }

    public void onStart(Intent intent, int startId) {
        // TO DO
    }

    public IBinder onUnBind(Intent arg0) {
        // TO DO Auto-generated method
        return null;
    }

    public void onStop() {

    }

    public void onPause() {

    }

    @Override
    public void onDestroy() {
        player.stop();
        player.release();
    }

    @Override
    public void onLowMemory() {

    }
}

This solved the issue for me:

Uninstall the Visual Studio 2010 redistributable package if you have it installed already, and then install Microsoft Windows 7 SDK.

FYI, I found I needed to put matplotlib.use('Agg') first in Python import order. For what I was doing (unit testing needed to be headless) that meant putting

import matplotlib
matplotlib.use('Agg')

at the top of my master test script. I didn't have to touch any other files.

You can get active store information like this:

Mage::app()->getStore();  // for store object
Mage::app()->getStore()->getStoreId;  // for store ID

Console.WriteLine allows the user to specify a position in a string.

See sample:

string str = "Tigger"; Console.WriteLine( str[0] ); //returns "T"; Console.WriteLine( str[2] ); //returns "g";

There you go!

The Python pprint module actually already sorts dictionaries by key. In versions prior to Python 2.5, the sorting was only triggered on dictionaries whose pretty-printed representation spanned multiple lines, but in 2.5.X and 2.6.X, all dictionaries are sorted.

Generally, though, if you're writing data structures to a file and want them human-readable and writable, you might want to consider using an alternate format like YAML or JSON. Unless your users are themselves programmers, having them maintain configuration or application state dumped via pprint and loaded via eval can be a frustrating and error-prone task.

i faced the same issue few days earlier for my IONIC 4 Project. when i uploaded my IPA, i got this warnings from App Store Connect.

I fixed the "Missing Purpose String in info.plist" issue, by the following steps. hope it will also work for you.

1. Goto your "info.plist" file.

2. Find this key, called Privacy - Photo Library Usage Description. if it's not present there, add a new one and it's value, like below image.

Thanks.

If you use a stringbuilder, it would be efficient to initalize the length when you create the object. Length is going to be 2*lengthofString-1.

Or creating a char array and converting it back to the string would yield the same result.

Aand when you write some code please be sure that you write a few test cases as well, it will make your solution complete.

Calling non-static methods statically generates an E_STRICT level warning.

Unity is just an IoC "container". Google StructureMap and try it out instead. A bit easier to grok, I think, when the IoC stuff is new to you.

Basically, if you understand IoC then you understand that what you're doing is inverting the control for when an object gets created.

Without IoC:

public class MyClass
{
   IMyService _myService; 

   public MyClass()
   {
      _myService = new SomeConcreteService();    
   }
}

With IoC container:

public class MyClass
{
   IMyService _myService; 

   public MyClass(IMyService myService)
   {
      _myService = myService;    
   }
}

Without IoC, your class that relies on the IMyService has to new-up a concrete version of the service to use. And that is bad for a number of reasons (you've coupled your class to a specific concrete version of the IMyService, you can't unit test it easily, you can't change it easily, etc.)

With an IoC container you "configure" the container to resolve those dependencies for you. So with a constructor-based injection scheme, you just pass the interface to the IMyService dependency into the constructor. When you create the MyClass with your container, your container will resolve the IMyService dependency for you.

Using StructureMap, configuring the container looks like this:

StructureMapConfiguration.ForRequestedType<MyClass>().TheDefaultIsConcreteType<MyClass>();
StructureMapConfiguration.ForRequestedType<IMyService>().TheDefaultIsConcreteType<SomeConcreteService>();

So what you've done is told the container, "When someone requests the IMyService, give them a copy of the SomeConcreteService." And you've also specified that when someone asks for a MyClass, they get a concrete MyClass.

That's all an IoC container really does. They can do more, but that's the thrust of it - they resolve dependencies for you, so you don't have to (and you don't have to use the "new" keyword throughout your code).

Final step: when you create your MyClass, you would do this:

var myClass = ObjectFactory.GetInstance<MyClass>();

Hope that helps. Feel free to e-mail me.

This simplest ways is to add the "checked attribute.

<label for="tag_1">Tag 1</label>
<input type="checkbox" name="tag_1" id="tag_1" value="yes" 
    <?php if($tag_1_saved_value === 'yes') echo 'checked="checked"';?> />

To get a inplace like result with grep you can do this:

echo "$(grep -v "pattern" filename)" >filename

In ng6 you need to use this command, according to a similar post:

ng config schematics.@schematics/angular:component '{ styleext: "scss"}'

I would do it something along these lines:

class Foo{
...
};

int main(){
  Foo* arrayOfFoo[100]; //[1]

  arrayOfFoo[0] = new Foo; //[2]
}

[1] This makes an array of 100 pointers to Foo-objects. But no Foo-objects are actually created.

[2] This is one possible way to instantiate an object, and at the same time save a pointer to this object in the first position of your array.

It seems to be a browser bug.

.img-responsive in <fieldset> have the same behaviour.

I had to extract numbers first from a list of float strings:

   df4['sscore'] = df4['simscore'].str.findall('\d+\.\d+')

then each convert to a float:

   ad=[]
   for z in range(len(df4)):
      ad.append([float(i) for i in df4['sscore'][z]])

in the end assign all floats to a dataframe as float64:

   df4['fscore'] = np.array(ad,dtype=float)

Recently came upon a case where this was not true, TI C28x boards can have a sizeof pointer == 1, since a byte for those boards is 16-bits, and pointer size is 16 bits. To make matters more confusing, they also have far pointers which are 22-bits. I'm not really sure what sizeof far pointer would be.

In general, DSP boards can have weird integer sizes.

So pointer sizes can still be weird in 2020 if you are looking in weird places

Look this example.

CREATE TABLE [dbo].#TestTable(
    [id] [int] NOT NULL,
    [create_date] [date] NOT NULL,
    [info1] [varchar](50) NOT NULL,
    [info2] [varchar](50) NOT NULL,
)

Insert some data

INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (1, '1/1/09', 'Blue', 'Green')
INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (1, '1/2/09', 'Red', 'Yellow')
INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (1, '1/3/09', 'Orange', 'Purple')
INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (2, '1/1/09', 'Yellow', 'Blue')
INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (2, '1/5/09', 'Blue', 'Orange')
INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (3, '1/2/09', 'Green', 'Purple')
INSERT INTO dbo.#TestTable (id, create_date, info1, info2)
VALUES (3, '1/8/09', 'Red', 'Blue')

Repeat same Values for 1

INSERT INTO dbo.#TestTable (id, create_date, info1, info2) VALUES (1, '1/1/09', 'Blue', 'Green')

Look All

SELECT * FROM #TestTable

Look your results

SELECT Id,
    create_date,
    info1,
    info2,
    ROW_NUMBER() OVER (PARTITION BY Id ORDER BY create_date DESC) AS RowId,
    RANK() OVER(PARTITION BY Id ORDER BY create_date DESC)    AS [RANK]

Pandas uses matplotlib as a library for basic plots. The easiest way in your case will using the following:

import pandas as pd
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
df.plot(x='col_name_1', y='col_name_2', style='o')

However, I would recommend to use seaborn as an alternative solution if you want have more customized plots while not going into the basic level of matplotlib. In this case you the solution will be following:

import pandas as pd
import seaborn as sns
import numpy as np

#creating sample data 
sample_data={'col_name_1':np.random.rand(20),
      'col_name_2': np.random.rand(20)}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df)

In general, you need to use FormatMessage to convert from a Win32 error code to text.

From the MSDN documentation:

Formats a message string. The function requires a message definition as input. The message definition can come from a buffer passed into the function. It can come from a message table resource in an already-loaded module. Or the caller can ask the function to search the system's message table resource(s) for the message definition. The function finds the message definition in a message table resource based on a message identifier and a language identifier. The function copies the formatted message text to an output buffer, processing any embedded insert sequences if requested.

The declaration of FormatMessage:

DWORD WINAPI FormatMessage(
  __in      DWORD dwFlags,
  __in_opt  LPCVOID lpSource,
  __in      DWORD dwMessageId, // your error code
  __in      DWORD dwLanguageId,
  __out     LPTSTR lpBuffer,
  __in      DWORD nSize,
  __in_opt  va_list *Arguments
);

For anyone who is also trying to call .format() on a long string, and is unable to use some of the most popular string wrapping techniques without breaking the subsequent .format( call, you can do str.format("", 1, 2) instead of "".format(1, 2). This lets you break the string with whatever technique you like. For example:

logger.info("Skipping {0} because its thumbnail was already in our system as {1}.".format(line[indexes['url']], video.title))

can be

logger.info(str.format(("Skipping {0} because its thumbnail was already"
+ "in our system as {1}"), line[indexes['url']], video.title))

Otherwise, the only possibility is using line ending continuations, which I personally am not a fan of.

I believe that it is virtually never correct to use nolock.

If you are reading a single row, then the correct index means that you won't need NOLOCK as individual row actions are completed quickly.

If you are reading many rows for anything other than temporary display, and care about being able repeat the result, or defend by the number produced, then NOLOCK is not appropriate.

NOLOCK is a surrogate tag for "i don't care if this answer contains duplicate rows, rows which are deleted, or rows which were never inserted to begin with because of rollback"

Errors which are possible under NOLOCK:

• Rows which match are not returned at all.
• single rows are returned multiple times (including multiple instances of the same primary key)
• Rows which do not match are returned.

Any action which can cause a page split while the noLock select is running can cause these things to occur. Almost any action (even a delete) can cause a page split.

Therefore: if you "know" that the row won't be changed while you are running, don't use nolock, as an index will allow efficient retrieval.

If you suspect the row can change while the query is running, and you care about accuracy, don't use nolock.

If you are considering NOLOCK because of deadlocks, examine the query plan structure for unexpected table scans, trace the deadlocks and see why they occur. NOLOCK around writes can mean that queries which previously deadlocked will potentially both write the wrong answer.

Parse that string into a Date object:

var myDate = new Date('10/11/1955 10:40:50 AM');

Then use the usual methods to get the date's day of month (getDate) / month (getMonth) / year (getFullYear).

var noTime = new Date(myDate.getFullYear(), myDate.getMonth(), myDate.getDate());

try changing the connection port to 8012

open xampp as administrator

Mysql config => my.ini change the port from 3306 to 8012

close and run it again I hope it will work.

I noticed that if the user enters a string of text but leaves the input without selecting any of the autocomplete options no value is set in the hidden input, even if the string coincides with one in the array. So, with help of the other answers I made this:

var $local_source = [{
        value: 1,
        label: "c++"
    }, {
        value: 2,
        label: "java"
    }, {
        value: 3,
        label: "php"
    }, {
        value: 4,
        label: "coldfusion"
    }, {
        value: 5,
        label: "javascript"
    }, {
        value: 6,
        label: "asp"
    }, {
        value: 7,
        label: "ruby"
    }];
    $('#search-fld').autocomplete({
        source: $local_source,
        select: function (event, ui) {
            $("#search-fld").val(ui.item.label); // display the selected text
            $("#search-fldID").val(ui.item.value); // save selected id to hidden input
            return false;
        },
        change: function( event, ui ) {

            var isInArray = false;

            $local_source.forEach(function(element, index){

                if ($("#search-fld").val().toUpperCase() == element.label.toUpperCase()) {
                    isInArray = true;
                    $("#search-fld").val(element.label); // display the selected text
                    $("#search-fldID").val(element.value); // save selected id to hidden input
                    console.log('inarray: '+isInArray+' label: '+element.label+' value: '+element.value);
                };

            });

            if(!isInArray){

                $("#search-fld").val(''); // display the selected text
                $( "#search-fldID" ).val( ui.item? ui.item.value : 0 );

            }
        } 

First uninstall your application from the emulator:

adb -e uninstall your.application.package.name

Then try to install the application again.

Make sure you are on the Lastest version

implementation 'com.github.bumptech.glide:glide:4.10.0'

Kotlin:

Glide.with(this)
        .asBitmap()
        .load(imagePath)
        .into(object : CustomTarget<Bitmap>(){
            override fun onResourceReady(resource: Bitmap, transition: Transition<in Bitmap>?) {
                imageView.setImageBitmap(resource)
            }
            override fun onLoadCleared(placeholder: Drawable?) {
                // this is called when imageView is cleared on lifecycle call or for
                // some other reason.
                // if you are referencing the bitmap somewhere else too other than this imageView
                // clear it here as you can no longer have the bitmap
            }
        })

Bitmap Size:

if you want to use the original size of the image use the default constructor as above, else You can pass your desired size for bitmap

into(object : CustomTarget<Bitmap>(1980, 1080)

Java:

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new CustomTarget<Bitmap>() {
            @Override
            public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }

            @Override
            public void onLoadCleared(@Nullable Drawable placeholder) {
            }
        });

Old Answer:

With compile 'com.github.bumptech.glide:glide:4.8.0' and below

Glide.with(this)
        .asBitmap()
        .load(path)
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {
                imageView.setImageBitmap(resource);
            }
        });

For compile 'com.github.bumptech.glide:glide:3.7.0' and below

Glide.with(this)
        .load(path)
        .asBitmap()
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
                imageView.setImageBitmap(resource);
            }
        });

Now you might see a warning SimpleTarget is deprecated

Reason:

The main point of deprecating SimpleTarget is to warn you about the ways in which it tempts you to break Glide's API contract. Specifically, it doesn't do anything to force you to stop using any resource you've loaded once the SimpleTarget is cleared, which can lead to crashes and graphical corruption.

The SimpleTarget still can be used as long you make sure you are not using the bitmap once the imageView is cleared.

XSLT 1.0 does not have an integer data type, only double. You can use number() to convert a string to a number.

Learn from another guy:

<a onclick="window.open(this.href,'_blank');return false;" href="http://www.foracure.org.au">Some Other Site</a>

It makes sense to me.

You may want to try the following:

SELECT  l.position, 
        l.username, 
        l.score,
        @curRow := @curRow + 1 AS row_number
FROM    league_girl l
JOIN    (SELECT @curRow := 0) r;

The JOIN (SELECT @curRow := 0) part allows the variable initialization without requiring a separate SET command.

Test case:

CREATE TABLE league_girl (position int, username varchar(10), score int);
INSERT INTO league_girl VALUES (1, 'a', 10);
INSERT INTO league_girl VALUES (2, 'b', 25);
INSERT INTO league_girl VALUES (3, 'c', 75);
INSERT INTO league_girl VALUES (4, 'd', 25);
INSERT INTO league_girl VALUES (5, 'e', 55);
INSERT INTO league_girl VALUES (6, 'f', 80);
INSERT INTO league_girl VALUES (7, 'g', 15);

Test query:

SELECT  l.position, 
        l.username, 
        l.score,
        @curRow := @curRow + 1 AS row_number
FROM    league_girl l
JOIN    (SELECT @curRow := 0) r
WHERE   l.score > 50;

Result:

+----------+----------+-------+------------+
| position | username | score | row_number |
+----------+----------+-------+------------+
|        3 | c        |    75 |          1 |
|        5 | e        |    55 |          2 |
|        6 | f        |    80 |          3 |
+----------+----------+-------+------------+
3 rows in set (0.00 sec)

In versions 2.9+ there is an isBetween function, but it's exclusive:

var compareDate = moment("15/02/2013", "DD/MM/YYYY");
var startDate   = moment("12/01/2013", "DD/MM/YYYY");
var endDate     = moment("15/01/2013", "DD/MM/YYYY");

// omitting the optional third parameter, 'units'
compareDate.isBetween(startDate, endDate); //false in this case

There is an inclusive workaround ...
x.isBetween(a, b) || x.isSame(a) || x.isSame(b)

... which is logically equivalent to
!(x.isBefore(a) || x.isAfter(b))

In version 2.13 the isBetween function has a fourth optional parameter, inclusivity.

Use it like this:

target.isBetween(start, finish, 'days', '()') // default exclusive
target.isBetween(start, finish, 'days', '(]') // right inclusive
target.isBetween(start, finish, 'days', '[)') // left inclusive
target.isBetween(start, finish, 'days', '[]') // all inclusive

More units to consider: years, months, days, hours, minutes, seconds, milliseconds

Note: units are still optional. Use null as the third argument to disregard units in which case milliseconds is the default granularity.

You say

I mean that it is not in use by any other application. If an application is using a port others can't use it until it becomes free.

But you can always connect to a port while others are using it if something's listening there. Otherwise, http port 80 would be a mess.

If your

   c = new TcpClient(ip, port);

fails, then nothing's listening there. Otherwise, it will connect, even if some other machine/application has a socket open to that ip and port.

You can use header files.

Good practice.

You can create a file called player.h declare all functions that are need by other cpp files in that header file and include it when needed.

player.h

#ifndef PLAYER_H    // To make sure you don't declare the function more than once by including the header multiple times.
#define PLAYER_H

#include "stdafx.h"
#include <SFML/Graphics.hpp>

int playerSprite();

#endif

player.cpp

#include "player.h"  // player.h must be in the current directory. or use relative or absolute path to it. e.g #include "include/player.h"

int playerSprite(){
    sf::Texture Texture;
    if(!Texture.loadFromFile("player.png")){
        return 1;
    }
    sf::Sprite Sprite;
    Sprite.setTexture(Texture);
    return 0;
}

main.cpp

#include "stdafx.h"
#include <SFML/Graphics.hpp>
#include "player.h"            //Here. Again player.h must be in the current directory. or use relative or absolute path to it.

int main()
{
    // ...
    int p = playerSprite();  
    //...

Not such a good practice but works for small projects. declare your function in main.cpp

#include "stdafx.h"
#include <SFML/Graphics.hpp>
// #include "player.cpp"


int playerSprite();  // Here

int main()
{
    // ...   
    int p = playerSprite();  
    //...

On the actual behavior, there is no difference. They all return None and that's it. However, there is a time and place for all of these. The following instructions are basically how the different methods should be used (or at least how I was taught they should be used), but they are not absolute rules so you can mix them up if you feel necessary to.

Using return None

This tells that the function is indeed meant to return a value for later use, and in this case it returns None. This value None can then be used elsewhere. return None is never used if there are no other possible return values from the function.

In the following example, we return person's mother if the person given is a human. If it's not a human, we return None since the person doesn't have a mother (let's suppose it's not an animal or something).

def get_mother(person):
    if is_human(person):
        return person.mother
    else:
        return None

Using return

This is used for the same reason as break in loops. The return value doesn't matter and you only want to exit the whole function. It's extremely useful in some places, even though you don't need it that often.

We've got 15 prisoners and we know one of them has a knife. We loop through each prisoner one by one to check if they have a knife. If we hit the person with a knife, we can just exit the function because we know there's only one knife and no reason the check rest of the prisoners. If we don't find the prisoner with a knife, we raise an alert. This could be done in many different ways and using return is probably not even the best way, but it's just an example to show how to use return for exiting a function.

def find_prisoner_with_knife(prisoners):
    for prisoner in prisoners:
        if "knife" in prisoner.items:
            prisoner.move_to_inquisition()
            return # no need to check rest of the prisoners nor raise an alert
    raise_alert()

Note: You should never do var = find_prisoner_with_knife(), since the return value is not meant to be caught.

Using no return at all

This will also return None, but that value is not meant to be used or caught. It simply means that the function ended successfully. It's basically the same as return in void functions in languages such as C++ or Java.

In the following example, we set person's mother's name and then the function exits after completing successfully.

def set_mother(person, mother):
    if is_human(person):
        person.mother = mother

Note: You should never do var = set_mother(my_person, my_mother), since the return value is not meant to be caught.

In general, it's not going to have enough of an impact to worry about, particularly since it's an intranet app and not a general-use Internet app. In particular, since it's intranet, SEO isn't a concern, since your intranet shouldn't be accessible to search engines. (and if it is, it isn't an intranet app).

And any framework worth it's salt either already has a default way to do this, or is fairly easy to change how it deals with multi-word URL components, so I wouldn't worry about it too much.

That said, here's how I see the various options:

Hyphen

• The biggest danger for hyphens is that the same character (typically) is also used for subtraction and numerical negation (ie. minus or negative).
• Hyphens feel awkward in URL components. They seem to only make sense at the end of a URL to separate words in the title of an article. Or, for example, the title of a Stack Overflow question that is added to the end of a URL for SEO and user-clarity purposes.

Underscore

• Again, they feel wrong in URL components. They break up the flow (and beauty/simplicity) of a URL, since they essentially add a big, heavy apparent space in the middle of a clean, flowing URL.
• They tend to blend in with underlines. If you expect your users to copy-paste your URLs into MS Word or other similar text-editing programs, or anywhere else that might pick up on a URL and style it with an underline (like links traditionally are), then you might want to avoid underscores as word separators. Particularly when printed, an underlined URL with underscores tends to look like it has spaces in it instead of underscores.

CamelCase

• By far my favorite, since it makes the URLs seem to flow better and doesn't have any of the faults that the previous two options do.
• Can be slightly harder to read for people that have a hard time differentiating upper-case from lower-case, but this shouldn't be much of an issue in a URL, because most "words" should be URL components and separated by a / anyways. If you find that you have a URL component that is more than 2 "words" long, you should probably try to find a better name for that concept.
• It does have a possible issue with case sensitivity, but most platforms can be adjusted to be either case-sensitive or case-insensitive. Any it's only really an issue for 2 cases: a.) humans typing the URL in, and b.) Programmers (since we are not human) typing the URL in. Typos are always a problem, regardless of case sensitivity, so this is no different that all one case.

Another solution without you having to manually mess around with the Unicode characters can be found in Making Font Awesome awesome - Using icons without i-tags (disclaimer: I wrote this article).

In a nutshell, you can create a new class like this:

.icon::before {
    display: inline-block;
    margin-right: .5em;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
    transform: translate(0, 0);
}

And then use it with any icon, for example:

<a class="icon fa-car" href="#">This is a link</a>

If it's 20 and lower, you can just use the unicode characters ? ? ... ?

I created a C# implementation of Tuples, which solves the problem generically for between two and five values - here's the blog post, which contains a link to the source.

I use the Heroku Scheduler addon provided by Heroku for free. Once added it is simple as creating a job with 'curl http://yourapp.herokuapp.com' and a 10 min interval.

I just crafted this as I needed a good, simple way.

If it gets to the final digit, and if it is a zero, it will stay.

You could also use a foreach loop instead for super long strings.

I just replace each leading oldChar with the newChar.

This is great for a problem I just solved, after formatting an int into a string.

    /* Like this: */
    int counterMax = 1000;
    int counter = ...;
    string counterString = counter.ToString($"D{counterMax.ToString().Length}");
    counterString = RemoveLeadingChars('0', ' ', counterString);
    string fullCounter = $"({counterString}/{counterMax})";
    // = (   1/1000) ... ( 430/1000) ... (1000/1000)

    static string RemoveLeadingChars(char oldChar, char newChar, char[] chars)
    {
        string result = "";
        bool stop = false;
        for (int i = 0; i < chars.Length; i++)
        {
            if (i == (chars.Length - 1)) stop = true;
            if (!stop && chars[i] == oldChar) chars[i] = newChar;
            else stop = true;
            result += chars[i];
        }
        return result;
    }

    static string RemoveLeadingChars(char oldChar, char newChar, string text)
    {
        return RemoveLeadingChars(oldChar, newChar, text.ToCharArray());
    }

I always tend to make my functions suitable for my own library, so there are options.

JavaScript Object <-> JSON String

JSON.stringify() <-> JSON.parse()

JSON.stringify(obj) - Takes any serializable object and returns the JSON representation as a string.

JSON.stringify() -> Object To String.

JSON.parse(string) - Takes a well formed JSON string and returns the corresponding JavaScript object.

JSON.parse() -> String To Object.

Explanation: JSON.stringify(obj [, replacer [, space]]);

Replacer/Space - optional or takes integer value or you can call interger type return function.

function replacer(key, value) {
    if (typeof value === 'number' && !isFinite(value)) {
        return String(value);
    }
    return value;
}

• Replacer Just Use for replace non finite no with null.
• Space use for indenting Json String by space

Non VBA Solution:

Use Conditional Formatting rule with formula: =ISNA(A1) (to highlight cells with all errors - not only #N/A, use =ISERROR(A1))

VBA Solution:

Your code loops through 50 mln cells. To reduce number of cells, I use .SpecialCells(xlCellTypeFormulas, 16) and .SpecialCells(xlCellTypeConstants, 16)to return only cells with errors (note, I'm using If cell.Text = "#N/A" Then)

Sub ColorCells()
    Dim Data As Range, Data2 As Range, cell As Range
    Dim currentsheet As Worksheet

    Set currentsheet = ActiveWorkbook.Sheets("Comparison")

    With currentsheet.Range("A2:AW" & Rows.Count)
        .Interior.Color = xlNone
        On Error Resume Next
        'select only cells with errors
        Set Data = .SpecialCells(xlCellTypeFormulas, 16)
        Set Data2 = .SpecialCells(xlCellTypeConstants, 16)
        On Error GoTo 0
    End With

    If Not Data2 Is Nothing Then
        If Not Data Is Nothing Then
            Set Data = Union(Data, Data2)
        Else
            Set Data = Data2
        End If
    End If

    If Not Data Is Nothing Then
        For Each cell In Data
            If cell.Text = "#N/A" Then
               cell.Interior.ColorIndex = 4
            End If
        Next
    End If
End Sub

Note, to highlight cells witn any error (not only "#N/A"), replace following code

If Not Data Is Nothing Then
   For Each cell In Data
       If cell.Text = "#N/A" Then
          cell.Interior.ColorIndex = 3
       End If
   Next
End If

with

If Not Data Is Nothing Then Data.Interior.ColorIndex = 3

UPD: (how to add CF rule through VBA)

Sub test()
    With ActiveWorkbook.Sheets("Comparison").Range("A2:AW" & Rows.Count).FormatConditions
        .Delete
        .Add Type:=xlExpression, Formula1:="=ISNA(A1)"
        .Item(1).Interior.ColorIndex = 3
    End With
End Sub

since answers are disappointing I would like suggest a way in which I got deleted stuff back.

I use an ide to code and accidently I used rm -rf from terminal to remove complete folder. Thanks to ide I recoved it back by reverting the change from ide's local history.

(my ide is intelliJ but all ide's support history backup)

The reason your attempt wasn't working, is because the two animations (fade-in and fade-out) were working against each other.

Right before an object became visible, it was still invisible and so the animation for fading-out would run. Then, the fraction of a second later when that same object had become visible, the fade-in animation would try to run, but the fade-out was still running. So they would work against each other and you would see nothing.

Eventually the object would become visible (most of the time), but it would take a while. And if you would scroll down by using the arrow-button at the button of the scrollbar, the animation would sort of work, because you would scroll using bigger increments, creating less scroll-events.

Enough explanation, the solution (JS, CSS, HTML):

$(window).on("load",function() {_x000D_
  $(window).scroll(function() {_x000D_
    var windowBottom = $(this).scrollTop() + $(this).innerHeight();_x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")==0) {$(this).fadeTo(500,1);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")==1) {$(this).fadeTo(500,0);}_x000D_
      }_x000D_
    });_x000D_
  }).scroll(); //invoke scroll-handler on page-load_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_
}

• I wrapped the fade-codeline in an if-clause: if ($(this).css("opacity")==0) {...}. This makes sure the object is only faded in when the opacity is 0. Same goes for fading out. And this prevents the fade-in and fade-out from working against each other, because now there's ever only one of the two running at one time on an object.
• I changed .animate() to .fadeTo(). It's jQuery's specialized function for opacity, a lot shorter to write and probably lighter than animate.
• I changed .position() to .offset(). This always calculates relative to the body, whereas position is relative to the parent. For your case I believe offset is the way to go.
• I changed $(window).height() to $(window).innerHeight(). The latter is more reliable in my experience.
• Directly after the scroll-handler, I invoke that handler once on page-load with $(window).scroll();. Now you can give all desired objects on the page the .fade class, and objects that should be invisible at page-load, will be faded out immediately.
• I removed #container from both HTML and CSS, because (at least for this answer) it isn't necessary. (I thought maybe you needed the height:2000px because you used .position() instead of .offset(), otherwise I don't know. Feel free of course to leave it in your code.)

UPDATE

If you want opacity values other than 0 and 1, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowBottom = $(window).scrollTop() + $(window).innerHeight();_x000D_
    var min = 0.3;_x000D_
    var max = 0.7;_x000D_
    var threshold = 0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectBottom = $(this).offset().top + $(this).outerHeight();_x000D_
      _x000D_
      /* If the element is completely within bounds of the window, fade it in */_x000D_
      if (objectBottom < windowBottom) { //object comes into view (scrolling down)_x000D_
        if ($(this).css("opacity")<=min+threshold || pageLoad) {$(this).fadeTo(500,max);}_x000D_
      } else { //object goes out of view (scrolling up)_x000D_
        if ($(this).css("opacity")>=max-threshold || pageLoad) {$(this).fadeTo(500,min);}_x000D_
      }_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_
  padding: 50px;_x000D_
  background-color: lightgreen;_x000D_
  opacity: 1;_x000D_

• I added a threshold to the if-clause, see explanation below.
• I created variables for the threshold and for min/max at the start of the function. In the rest of the function these variables are referenced. This way, if you ever want to change the values again, you only have to do it in one place.
• I also added || pageLoad to the if-clause. This was necessary to make sure all objects are faded to the correct opacity on page-load. pageLoad is a boolean that is send along as an argument when fade() is invoked.
  I had to put the fade-code inside the extra function fade() {...}, in order to be able to send along the pageLoad boolean when the scroll-handler is invoked.
  I did't see any other way to do this, if anyone else does, please leave a comment.

Explanation:
The reason the code in your fiddle didn't work, is because the actual opacity values are always a little off from the value you set it to. So if you set the opacity to 0.3, the actual value (in this case) is 0.300000011920929. That's just one of those little bugs you have to learn along the way by trail and error. That's why this if-clause won't work: if ($(this).css("opacity") == 0.3) {...}.

I added a threshold, to take that difference into account: == 0.3 becomes <= 0.31.
(I've set the threshold to 0.01, this can be changed of course, just as long as the actual opacity will fall between the set value and this threshold.)

The operators are now changed from == to <= and >=.

UPDATE 2:

If you want to fade the elements based on their visible percentage, use the following code:

$(window).on("load",function() {_x000D_
  function fade(pageLoad) {_x000D_
    var windowTop=$(window).scrollTop(), windowBottom=windowTop+$(window).innerHeight();_x000D_
    var min=0.3, max=0.7, threshold=0.01;_x000D_
    _x000D_
    $(".fade").each(function() {_x000D_
      /* Check the location of each desired element */_x000D_
      var objectHeight=$(this).outerHeight(), objectTop=$(this).offset().top, objectBottom=$(this).offset().top+objectHeight;_x000D_
      _x000D_
      /* Fade element in/out based on its visible percentage */_x000D_
      if (objectTop < windowTop) {_x000D_
        if (objectBottom > windowTop) {$(this).fadeTo(0,min+((max-min)*((objectBottom-windowTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if (objectBottom > windowBottom) {_x000D_
        if (objectTop < windowBottom) {$(this).fadeTo(0,min+((max-min)*((windowBottom-objectTop)/objectHeight)));}_x000D_
        else if ($(this).css("opacity")>=min+threshold || pageLoad) {$(this).fadeTo(0,min);}_x000D_
      } else if ($(this).css("opacity")<=max-threshold || pageLoad) {$(this).fadeTo(0,max);}_x000D_
    });_x000D_
  } fade(true); //fade elements on page-load_x000D_
  $(window).scroll(function(){fade(false);}); //fade elements on scroll_x000D_
});

.fade {_x000D_
  margin: 50px;_x000D_

The SKU example used in the documentation was to provide the allowed characters in a new user-specified SKU.

I stumbled across Android XRef the other day and found it useful, especially since it is backed by OpenGrok which offers insanely awesome and blindingly fast search.

match_parent is not supported, so use android:layout_width="0dp". With 0dp, you can think of your constraints as 'scalable' rather than 'filling whats left'.

Also, 0dp can be defined by a position, where match_parent relies on it's parent for it's position (x,y and width, height)

You can use the TextView for the same purpose, But if you want to use the same with the ImageView then you have to create a class and extends the ImageView then use onDraw() method to paint the text on to the canvas. for more details visit to http://developer.android.com/reference/android/graphics/Canvas.html

Yes, that is possible. At its lowest level Bluetooth allows you to connect up to 7 devices to one master device. I have done this and it has worked well for me, but only on other platforms (linux) where I had lots of manual control - I've never tried that on Android and there are some possible complications so you will need to do some testing to be certain.

One of the issues is that you need the tablet to the master and Android doesn't give you any explicit control of this. It is likely that this won't be a problem because * the tablet will automatically become the master when you try to connect a second device to it, or * you will be able to control the master/slave roles by how you setup your socket connection

I will caution though that most apps using Bluetooth on mobile are not attempting many simultaneous connections and Bluetooth can be a bit fragile, e.g. what if two devices already have a Bluetooth connection for some other app - how might that affect the roles?

For Dockerfile, this works for me:

RUN locale-gen en_US.UTF-8  
ENV LANG en_US.UTF-8  
ENV LANGUAGE en_US:en  
ENV LC_ALL en_US.UTF-8  

How to install locale-gen?

docker ubuntu /bin/sh: 1: locale-gen: not found

You can also embed it in the php. E.g.

<?php
    echo "<p style='color:blue; border:2px red solid;'>CSS Styling in php</p>";
?>

hope this help for anyone in the future.

Why is there no answer for using Reflection API?

private static Object cloneObject(Object obj){
        try{
            Object clone = obj.getClass().newInstance();
            for (Field field : obj.getClass().getDeclaredFields()) {
                field.setAccessible(true);
                field.set(clone, field.get(obj));

It can be used to get the inverse cumulative distribution function (inv_cdf - inverse of the cdf), also known as the quantile function or the percent-point function for a given mean (mu) and standard deviation (sigma):

from statistics import NormalDist

NormalDist(mu=10, sigma=2).inv_cdf(0.95)
# 13.289707253902943

Which can be simplified for the standard normal distribution (mu = 0 and sigma = 1):

NormalDist().inv_cdf(0.95)
# 1.6448536269514715

It sounds to me like you already built your own IoC container (using the various patterns which were described by Martin Fowler) and are asking why someone else's implementation is better than yours.

So, you have a bunch of code that already works. And are wondering why you would want to replace it with someone else's implementation.

Pros for considering a third-party IoC container

• You get bugs fixed for free
• The library design may be better than yours
• People may be already familiar with the particular library
• The library may be faster than yours
• It may have some features you wish you implemented but never had time to (do you have a service locater?)

Cons

• You get bugs introduced, for free :)
• The library design may be worse than yours
• You have to learn a new API
• Too many features you will never use
• It's usually harder to debug code you did not write
• Migrating from a previous IoC container may be tedious

So, weigh your pros against your cons and make a decision.

Maybe you are trying to do

string combindedString = string.Join( ",", myList.ToArray() );

You can replace "," with what you want to split the elements in the list by.

Edit: As mention in the comments you could also do

string combindedString = string.Join( ",", myList);

Reference:

Join<T>(String, IEnumerable<T>) 
Concatenates the members of a collection, using the specified separator between each member.

I thought that @Steven 's answer was the best one, and took care of a lot more cases than if the incoming value was just a string. I wanted to extend it a bit and offer the following:

function isTrue(value){
    if (typeof(value) === 'string'){
        value = value.trim().toLowerCase();
    }
    switch(value){
        case true:
        case "true":
        case 1:
        case "1":
        case "on":
        case "yes":
            return true;
        default: 
            return false;
    }
}

It's not necessary to cover all the false cases if you already know all of the true cases you'd have to account for. You can pass anything into this method that could pass for a true value (or add others, it's pretty straightforward), and everything else would be considered false

You can also try using multiprocessing.Process with daemon=True; the process.start() method does not block and you can return a response/status immediately to the caller while your expensive function executes in the background.

I experienced similar problem while working with falcon framework and using daemon process helped.

You'd need to do the following:

from multiprocessing import Process

@app.route('/render/<id>', methods=['POST'])
def render_script(id=None):
    ...
    heavy_process = Process(  # Create a daemonic process with heavy "my_func"
        target=my_func,
        daemon=True
    )
    heavy_process.start()
    return Response(
        mimetype='application/json',
        status=200
    )

# Define some heavy function
def my_func():
    time.sleep(10)
    print("Process finished")

You should get a response immediately and, after 10s you should see a printed message in the console.

NOTE: Keep in mind that daemonic processes are not allowed to spawn any child processes.

Instead of using the % unit – the width/height of another element – you should use vh and vw.
Your code would be:

your table {
  width: 100vw;
  height: 100vh;
}

But, if the document is smaller than 100vh or 100vw, then you need to set the size to the document's size.

(table).style.width = window.innerWidth;
(table).style.height = window.innerHeight;

This worked for me (1.3.0.M5) :

import org.springframework.boot.autoconfigure.jdbc.*;
import org.springframework.boot.autoconfigure.orm.jpa.*;

@Configuration
@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
public class Application {

Exclude both classes.

It did not work with

@SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})

You can create a symbolic link with a shorter directory. First open command line for example by Shift + RightClick in your desired folder with a shorter path (you may have to run it as administrator).

Then type with relative or absolute paths:

mklink ShortPath\To\YourLinkedSolution C:\Path\To\Your\Solution /D

And then start the Solution from the shorter path. The advantage here is: You don't have to move anything.

var x = moment();

//date.format(moment.ISO_8601); // error

moment("2010-01-01T05:06:07", ["YYYY", moment.ISO_8601]);; // error
document.write(x);

I have a similar situation, but I use the key and the certificate in different files.

in my case you can check the matching of the key and the lock by comparing the hashes (see https://michaelheap.com/curl-58-unable-to-set-private-key-file-server-key-type-pem/). This helped me to identify inconsistencies.

Since this is a popular question, I would like to add that in Elasticsearch version 2 things changed a bit.

Instead of filtered query, one should use bool query in the top level.

If you don't care about the score of must parts, then put those parts into filter key. No scoring means faster search. Also, Elasticsearch will automatically figure out, whether to cache them, etc. must_not is equally valid for caching.

Reference: https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-bool-query.html

Also, mind that "gte": "now" cannot be cached, because of millisecond granularity. Use two ranges in a must clause: one with now/1h and another with now so that the first can be cached for a while and the second for precise filtering accelerated on a smaller result set.

I was answering similar question and got yet another idea how to achieve this without use of eval():

const source = "alert('test')";
const el = document.createElement("script");
el.src = URL.createObjectURL(new Blob([source], { type: 'text/javascript' }));
document.head.appendChild(el);

In the code above you basically create Blob, containing your script, in order to create Object URL (representation of File or Blob object in browser memory). Since you have src property on <script> tag, the script will be executed the same way as if it was loaded from any other URL.

For Power-Shell

./adb shell getprop | Select-String -Pattern '(model)|(version.sdk)|(manufacturer)|(platform)|(serialno)|(product.name)|(brand)'

For linux(burrowing asnwer from @0x8BADF00D)

Yes, the upload element is protected from direct manipulation in different browsers. However, you could erase the element from the DOM tree and then insert a new one in its place via JavaScript. That would give you the same result.

Something along the lines of:

$('#container-element').html('<input id="upload-file" type="file"/>');

I'd the same issue on a WCF project on VS2017. When I debug, it gives errors like not able to get meta data, but it turns out the port was used by other process. I got some idea from here, and finally figure out where the port was kept. There are 2 places: 1. C:...to your solution folder....vs\config\applicationhost.config. Inside, you can find the site that you debug. Under , remove the that has port issue. 2. C:...to your project folder...\, you will see a file with ProjectName.csproj.user. Remove this file.

So, close the solution, remove the and the user file mentioned above, then reopen the solution, VS will find another suitable port for the site.

use:

/^[ A-Za-z0-9_@./#&+-]*$/

You can also use the character class \w to replace A-Za-z0-9_

You can use this function:

function post_unserialize( $key ){
  $post_data = array();
  $post_data = $_POST[ $key ];
  unset($_POST[ $key ]);
  parse_str($post_data, $post_data);
  $_POST = array_merge($_POST, $post_data);
}

How to use it

$_POST['serialized_data'] = 'var1=1&var2=2&var3=3';
post_unserialize( 'serialized_data' );

I had the issue during transformClassesWithDexFor when the maximum heap size for the Gradle daemon is superior to 4Go. By changing my ~/gradle.properties with org.gradle.jvmargs=-Xmx2048m (meaning I reduce the heap size to 2Go instead of 4Go) the dex then runs in a separate process and I no longer have the issue.

14:52:26.412 [WARN] [org.gradle.api.Project]

Running dex as a separate process.

To run dex in process, the Gradle daemon needs a larger heap.

It currently has 2048 MB.

For faster builds, increase the maximum heap size for the Gradle daemon to at least 4608 MB (based on the dexOptions.javaMaxHeapSize = 4g).

To do this set org.gradle.jvmargs=-Xmx4608M in the project gradle.properties.

Overview of Scanner.hasNextXXX methods

java.util.Scanner has many hasNextXXX methods that can be used to validate input. Here's a brief overview of all of them:

• hasNext() - does it have any token at all?
• hasNextLine() - does it have another line of input?
• For Java primitives
  • hasNextInt() - does it have a token that can be parsed into an int?
  • Also available are hasNextDouble(), hasNextFloat(), hasNextByte(), hasNextShort(), hasNextLong(), and hasNextBoolean()
  • As bonus, there's also hasNextBigInteger() and hasNextBigDecimal()
  • The integral types also has overloads to specify radix (for e.g. hexadecimal)
• Regular expression-based
  • hasNext(String pattern)
  • hasNext(Pattern pattern) is the Pattern.compile overload

Scanner is capable of more, enabled by the fact that it's regex-based. One important feature is useDelimiter(String pattern), which lets you define what pattern separates your tokens. There are also find and skip methods that ignores delimiters.

The following discussion will keep the regex as simple as possible, so the focus remains on Scanner.

Example 1: Validating positive ints

Here's a simple example of using hasNextInt() to validate positive int from the input.

Scanner sc = new Scanner(System.in);
int number;
do {
    System.out.println("Please enter a positive number!");
    while (!sc.hasNextInt()) {
        System.out.println("That's not a number!");
        sc.next(); // this is important!
    }
    number = sc.nextInt();
} while (number <= 0);
System.out.println("Thank you! Got " + number);

Here's an example session:

Please enter a positive number!
five
That's not a number!
-3
Please enter a positive number!
5
Thank you! Got 5

Note how much easier Scanner.hasNextInt() is to use compared to the more verbose try/catch Integer.parseInt/NumberFormatException combo. By contract, a Scanner guarantees that if it hasNextInt(), then nextInt() will peacefully give you that int, and will not throw any NumberFormatException/InputMismatchException/NoSuchElementException.

Related questions

• How to use Scanner to accept only valid int as input
• How do I keep a scanner from throwing exceptions when the wrong type is entered? (java)

Example 2: Multiple hasNextXXX on the same token

Note that the snippet above contains a sc.next() statement to advance the Scanner until it hasNextInt(). It's important to realize that none of the hasNextXXX methods advance the Scanner past any input! You will find that if you omit this line from the snippet, then it'd go into an infinite loop on an invalid input!

This has two consequences:

• If you need to skip the "garbage" input that fails your hasNextXXX test, then you need to advance the Scanner one way or another (e.g. next(), nextLine(), skip, etc).
• If one hasNextXXX test fails, you can still test if it perhaps hasNextYYY!

Here's an example of performing multiple hasNextXXX tests.

Scanner sc = new Scanner(System.in);
while (!sc.hasNext("exit")) {
    System.out.println(
        sc.hasNextInt() ? "(int) " + sc.nextInt() :
        sc.hasNextLong() ? "(long) " + sc.nextLong() :  
        sc.hasNextDouble() ? "(double) " + sc.nextDouble() :
        sc.hasNextBoolean() ? "(boolean) " + sc.nextBoolean() :
        "(String) " + sc.next()
    );
}

Here's an example session:

5
(int) 5
false
(boolean) false
blah
(String) blah
1.1
(double) 1.1
100000000000
(long) 100000000000
exit

Note that the order of the tests matters. If a Scanner hasNextInt(), then it also hasNextLong(), but it's not necessarily true the other way around. More often than not you'd want to do the more specific test before the more general test.

Example 3 : Validating vowels

Scanner has many advanced features supported by regular expressions. Here's an example of using it to validate vowels.

Scanner sc = new Scanner(System.in);
System.out.println("Please enter a vowel, lowercase!");
while (!sc.hasNext("[aeiou]")) {
    System.out.println("That's not a vowel!");
    sc.next();
}
String vowel = sc.next();
System.out.println("Thank you! Got " + vowel);

Here's an example session:

Please enter a vowel, lowercase!
5
That's not a vowel!
z
That's not a vowel!
e
Thank you! Got e

In regex, as a Java string literal, the pattern "[aeiou]" is what is called a "character class"; it matches any of the letters a, e, i, o, u. Note that it's trivial to make the above test case-insensitive: just provide such regex pattern to the Scanner.

• java.util.regex.Pattern

Example 4: Using two Scanner at once

Sometimes you need to scan line-by-line, with multiple tokens on a line. The easiest way to accomplish this is to use two Scanner, where the second Scanner takes the nextLine() from the first Scanner as input. Here's an example:

Scanner sc = new Scanner(System.in);
System.out.println("Give me a bunch of numbers in a line (or 'exit')");
while (!sc.hasNext("exit")) {
    Scanner lineSc = new Scanner(sc.nextLine());
    int sum = 0;
    while (lineSc.hasNextInt()) {
        sum += lineSc.nextInt();
    }
    System.out.println("Sum is " + sum);
}

Here's an example session:

Give me a bunch of numbers in a line (or 'exit')
3 4 5
Sum is 12
10 100 a million dollar
Sum is 110
wait what?
Sum is 0
exit

In addition to Scanner(String) constructor, there's also Scanner(java.io.File) among others.

Summary

• Scanner provides a rich set of features, such as hasNextXXX methods for validation.
• Proper usage of hasNextXXX/nextXXX in combination means that a Scanner will NEVER throw an InputMismatchException/NoSuchElementException.
• Always remember that hasNextXXX does not advance the Scanner past any input.
• Don't be shy to create multiple Scanner if necessary. Two simple Scanner is often better than one overly complex Scanner.
• Finally, even if you don't have any plans to use the advanced regex features, do keep in mind which methods are regex-based and which aren't. Any Scanner method that takes a String pattern argument is regex-based.
  • Tip: an easy way to turn any String into a literal pattern is to Pattern.quote it.

As this question is been 7 years before, in the latest version which I am using is numpy version 1.13, and python3, I am doing the same thing with adding a row to a matrix, remember to put a double bracket to the second argument, otherwise, it will raise dimension error.

In here I am adding on matrix A

1 2 3
4 5 6

with a row

7 8 9

same usage in np.r_

A= [[1, 2, 3], [4, 5, 6]]
np.append(A, [[7, 8, 9]], axis=0)

    >> array([[1, 2, 3],
              [4, 5, 6],
              [7, 8, 9]])
#or 
np.r_[A,[[7,8,9]]]

Just to someone's intersted, if you would like to add a column,

array = np.c_[A,np.zeros(#A's row size)]

following what we did before on matrix A, adding a column to it

np.c_[A, [2,8]]

>> array([[1, 2, 3, 2],
          [4, 5, 6, 8]])

Maybe this, if you want to add task as crontab:

#!/bin/bash
dir="/path/to/root"
lock=/tmp/update.lock
msglog="/var/log/update.log"

log()
{
        echo "$(date) ${1:-missing}" >> $msglog
}

if [ -f $lock ]; then
        log "Already run, exiting..."
else
        > $lock
        git -C ~/$dir remote update &> /dev/null
        checkgit=`git -C ~/$dir status`
        if [[ ! "$checkgit" =~ "Your branch is up-to-date" ]]; then
                log "-------------- Update ---------------"
                git -C ~/$dir pull &>> $msglog
                log "-------------------------------------"
        fi
        rm $lock

fi
exit 0

There is a lot of ways to achieve this. In regards to the way you are asking, with a hidden form element.

create this form element inside your form:

<input type="hidden" name="total" value="">

So your form like this:

<form id="sampleForm" name="sampleForm" method="post" action="phpscript.php">
<input type="hidden" name="total" id="total" value="">
<a href="#" onclick="setValue();">Click to submit</a>
</form>

Then your javascript something like this:

<script>
function setValue(){
    document.sampleForm.total.value = 100;
    document.forms["sampleForm"].submit();
}
</script>

Most likely you should increase Timeout parameter in apache conf (default value 120 sec)

For me, that happened because I had an empty component in my page -

<script type="text/x-magento-init">
   {
   ".page.messages": {
       "Magento_Ui/js/core/app": []        
      }
   }

Deleting this piece of code resolved the issue.

If you are using this line:

sessionFactory.getHibernateProperties().put("hibernate.dialect", env.getProperty("hibernate.dialect"));

make sure that env.getProperty("hibernate.dialect") is not null.

Objects which are immutable can not have their state changed after they have been created.

There are three main reasons to use immutable objects whenever you can, all of which will help to reduce the number of bugs you introduce in your code:

• It is much easier to reason about how your program works when you know that an object's state cannot be changed by another method
• Immutable objects are automatically thread safe (assuming they are published safely) so will never be the cause of those hard-to-pin-down multithreading bugs
• Immutable objects will always have the same Hash code, so they can be used as the keys in a HashMap (or similar). If the hash code of an element in a hash table was to change, the table entry would then effectively be lost, since attempts to find it in the table would end up looking in the wrong place. This is the main reason that String objects are immutable - they are frequently used as HashMap keys.

There are also some other optimisations you might be able to make in code when you know that the state of an object is immutable - caching the calculated hash, for example - but these are optimisations and therefore not nearly so interesting.

You may like to first create a dialogue by right clicking the project in solution explorer and in the code file type

dialogue1.show()

that's all !!!

open('myfile.dat', 'a') works for me, just fine.

in py3k your code raises ValueError:

>>> open('myfile.dat', 'rw')
Traceback (most recent call last):
  File "<pyshell#34>", line 1, in <module>
    open('myfile.dat', 'rw')
ValueError: must have exactly one of read/write/append mode

in python-2.6 it raises IOError.

You need to use get_serving_url from the Images API. As that page explains, you need to call create_gs_key() first to get the key to pass to the Images API.

You can do this by adding them to the locals object in a general middleware.

app.use(function (req, res, next) {
   res.locals = {
     siteTitle: "My Website's Title",
     pageTitle: "The Home Page",
     author: "Cory Gross",
     description: "My app's description",
   };
   next();
});

Locals is also a function which will extend the locals object rather than overwriting it. So the following works as well

res.locals({
  siteTitle: "My Website's Title",
  pageTitle: "The Home Page",
  author: "Cory Gross",
  description: "My app's description",
});

Full example

var app = express();

var middleware = {

    render: function (view) {
        return function (req, res, next) {
            res.render(view);
        }
    },

    globalLocals: function (req, res, next) {
        res.locals({ 
            siteTitle: "My Website's Title",
            pageTitle: "The Root Splash Page",
            author: "Cory Gross",
            description: "My app's description",
        });
        next();
    },

    index: function (req, res, next) {
        res.locals({
            indexSpecificData: someData
        });
        next();
    }

};


app.use(middleware.globalLocals);
app.get('/', middleware.index, middleware.render('home'));
app.get('/products', middleware.products, middleware.render('products'));

I also added a generic render middleware. This way you don't have to add res.render to each route which means you have better code reuse. Once you go down the reusable middleware route you'll notice you will have lots of building blocks which will speed up development tremendously.

In (the current) IPython 3.2.0 (Python 2 or 3)

Open the configuration file within the hidden folder .ipython

~/.ipython/profile_default/ipython_kernel_config.py

add the following line

c.IPKernelApp.matplotlib = 'inline'

add it straight after

c = get_config()

In your case you can use __FILE__ variable !
It should help.
It is one of predefined.

For the C-runtime go to the project settings, choose C/C++ then 'Code Generation'. Change the 'runtime library' setting to 'multithreaded' instead of 'multithreaded dll'.

If you are using any other libraries you may need to tell the linker to ignore the dynamically linked CRT explicitly.

For NetBeans to be able to interact with tomcat, it needs the user as setup in netbeans to be properly configured in the tomcat-users.xml file. NetBeans can do so automatically.

That is, within the tomcat-users.xml, which you can find in ${CATALINA_HOME}/conf, or ${CATALINA_BASE}/conf,

1. make sure that the user (as chosen in netbeans) is added the script-manager role

Example, change

<user password="tomcat" roles="manager,admin" username="tomcat"/>

To

<user password="tomcat" roles="manager-script,manager,admin" username="tomcat"/>

2. make sure that the manager-script role is declared

Add

<role rolename="manager-script"/>

Actually the netbeans online-help incorrectly states:

Username - Specifies the user name that the IDE uses to log into the server's manager application. The user must be associated with the manager role. The first time the IDE started the Tomcat Web Server, such as through the Start/Stop menu action or by executing a web component from the IDE, the IDE adds an admin user with a randomly-generated password to the tomcat-base-path/conf/tomcat-users.xml file. (Right-click the Tomcat Web server instance node in the Services window and select Properties. In the Properties dialog box, the Base Directory property points to the base-dir directory.) The admin user entry in the tomcat-users.xml file looks similar to the following: <user username="idea" password="woiehh" roles="manager"/>

The role should be manager-script, and not manager.

For a more complete tomcat-users.xml file:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>
  <role rolename="manager-script"/>
  <role rolename="manager-gui"/>
  <user password="tomcat" roles="manager-script" username="tomcat"/>
  <user password="pass" roles="manager-gui" username="me"/>
</tomcat-users>

There is another nice posting on why am I getting the deployment error?

This post will go through the following topics:

• Merging with index under different conditions
  • options for index-based joins: merge, join, concat
  • merging on indexes
  • merging on index of one, column of other
• effectively using named indexes to simplify merging syntax

_{BACK TO TOP}

Index-based joins

TL;DR

There are a few options, some simpler than others depending on the use case.

1. DataFrame.merge with left_index and right_index (or left_on and right_on using names indexes)
   • supports inner/left/right/full
   • can only join two at a time
   • supports column-column, index-column, index-index joins
2. DataFrame.join (join on index)
   • supports inner/left (default)/right/full
   • can join multiple DataFrames at a time
   • supports index-index joins
3. pd.concat (joins on index)
   • supports inner/full (default)
   • can join multiple DataFrames at a time
   • supports index-index joins

Index to index joins

Setup & Basics

import pandas as pd
import numpy as np

np.random.seed([3, 14])
left = pd.DataFrame(data={'value': np.random.randn(4)}, 
                    index=['A', 'B', 'C', 'D'])    
right = pd.DataFrame(data={'value': np.random.randn(4)},  
                     index=['B', 'D', 'E', 'F'])
left.index.name = right.index.name = 'idxkey'

left
           value
idxkey          
A      -0.602923
B      -0.402655
C       0.302329
D      -0.524349

right
 
           value
idxkey          
B       0.543843
D       0.013135
E      -0.326498
F       1.385076

Typically, an inner join on index would look like this:

left.merge(right, left_index=True, right_index=True)

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

Other joins follow similar syntax.

Notable Alternatives

1. DataFrame.join defaults to joins on the index. DataFrame.join does a LEFT OUTER JOIN by default, so how='inner' is necessary here.

    left.join(right, how='inner', lsuffix='_x', rsuffix='_y')
   
             value_x   value_y
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   Note that I needed to specify the lsuffix and rsuffix arguments since join would otherwise error out:

    left.join(right)
    ValueError: columns overlap but no suffix specified: Index(['value'], dtype='object')
   

   Since the column names are the same. This would not be a problem if they were differently named.

    left.rename(columns={'value':'leftvalue'}).join(right, how='inner')
   
            leftvalue     value
    idxkey                     
    B       -0.402655  0.543843
    D       -0.524349  0.013135
   

2. pd.concat joins on the index and can join two or more DataFrames at once. It does a full outer join by default, so how='inner' is required here..

    pd.concat([left, right], axis=1, sort=False, join='inner')
   
               value     value
    idxkey                    
    B      -0.402655  0.543843
    D      -0.524349  0.013135
   

   For more information on concat, see this post.

Index to Column joins

To perform an inner join using index of left, column of right, you will use DataFrame.merge a combination of left_index=True and right_on=....

right2 = right.reset_index().rename({'idxkey' : 'colkey'}, axis=1)
right2
 
  colkey     value
0      B  0.543843
1      D  0.013135
2      E -0.326498
3      F  1.385076

left.merge(right2, left_index=True, right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Other joins follow a similar structure. Note that only merge can perform index to column joins. You can join on multiple columns, provided the number of index levels on the left equals the number of columns on the right.

join and concat are not capable of mixed merges. You will need to set the index as a pre-step using DataFrame.set_index.

Effectively using Named Index [pandas >= 0.23]

If your index is named, then from pandas >= 0.23, DataFrame.merge allows you to specify the index name to on (or left_on and right_on as necessary).

left.merge(right, on='idxkey')

         value_x   value_y
idxkey                    
B      -0.402655  0.543843
D      -0.524349  0.013135

For the previous example of merging with the index of left, column of right, you can use left_on with the index name of left:

left.merge(right2, left_on='idxkey', right_on='colkey')

    value_x colkey   value_y
0 -0.402655      B  0.543843
1 -0.524349      D  0.013135

Appending data to an existing array is a natural thing to want to do for anyone with python experience. However, if you find yourself regularly appending to large arrays, you'll quickly discover that NumPy doesn't easily or efficiently do this the way a python list will. You'll find that every "append" action requires re-allocation of the array memory and short-term doubling of memory requirements. So, the more general solution to the problem is to try to allocate arrays to be as large as the final output of your algorithm. Then perform all your operations on sub-sets (slices) of that array. Array creation and destruction should ideally be minimized.

That said, It's often unavoidable and the functions that do this are:

for 2-D arrays:

• np.hstack
• np.vstack
• np.column_stack
• np.row_stack

for 3-D arrays (the above plus):

• np.dstack

for N-D arrays:

• np.concatenate

If you just want to add a string to it, the simple answer is:

ListBox.Items.Add("some text");

I have searched the best and the simplest answer to make 9-patch image. Now to make the 9 patch image is the easiest task.

From https://romannurik.github.io/AndroidAssetStudio/index.html you can make a 9-patch image for all the resolutions - XHDPI,HDPI,MDPI,LDPI in just one click.

It could be too late. But, I encountered similar problem and in my case the project had self reference. Hence, deleting it from the References worked like a charm!!!

Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

You can avoid this problem by

• accessing the lazy collection within a transaction.
• Initalizing the collection using Hibernate.initialize(obj);
• Fetch the collection in another transaction
• Use Fetch profiles to select lazy/non-lazy fetching runtime
• Set fetch to non-lazy (which is generally not recommended)

Further I would recommend looking at the related links to your right where this question has been answered many times before. Also see Hibernate lazy-load application design.

Here is slightly modified version. Changes are noted as code commentary.

For MySQL Workbench 6.1: in the home window click on the server instance(connection)/ or create a new one. In the thus opened 'connection' tab click on 'server' -> 'data import'. The rest of the steps remain as in Vishy's answer.

For me:

.ui-jqgrid .ui-jqgrid-bdiv {
   position: relative;
   margin: 0;
   padding: 0;

}

Of course remove the arrows

Using LEFT JOIN/IS NULL:

DELETE b FROM BLOB b 
  LEFT JOIN FILES f ON f.id = b.fileid 
      WHERE f.id IS NULL

Using NOT EXISTS:

DELETE FROM BLOB 
 WHERE NOT EXISTS(SELECT NULL
                    FROM FILES f
                   WHERE f.id = fileid)

Using NOT IN:

DELETE FROM BLOB
 WHERE fileid NOT IN (SELECT f.id 
                        FROM FILES f)

Warning

Whenever possible, perform DELETEs within a transaction (assuming supported - IE: Not on MyISAM) so you can use rollback to revert changes in case of problems.

If you don't want 3D border use:

border:#f00 1px solid;

You can use the pseudo-selector :checkbox with a call to jQuery's is function:

$('#myinput').is(':checkbox')

This is how you can go about it:

1. Close Eclipse
2. Download a jar plugin (let's assume its testNG.jar)
3. Copy testNG.jar to a certain folder (say C:\Project\resources\plugins)
4. In your Eclipse installation folder, there is a folder named dropins (could be C:\eclipse\dropins), create a .link file in that folder, (like plugins.link)
5. Open this file with any text editor and enter this one line:
   path=C:/Project/resources/plugins
   
6. Save the file and start Eclipse.

And you are good to go!

Please do not forget to change your backward slashes in your plugins folder path to forward slashes on step 5. I used to forget and it would take my time unnecessarily.

"Empty": only works on variables. Empty can mean different things for different variable types (check manual: http://php.net/manual/en/function.empty.php).

"isset": checks if the variable exists and checks for a true NULL or false value. Can be unset by calling "unset". Once again, check the manual.

Use of either one depends of the variable type you are using.

I would say, it's safer to check for both, because you are checking first of all if the variable exists, and if it isn't really NULL or empty.

"N/A" is a string and cannot be converted to a number. Catch the exception and handle it. For example:

    String text = "N/A";
    int intVal = 0;
    try {
        intVal = Integer.parseInt(text);
    } catch (NumberFormatException e) {
        //Log it if needed
        intVal = //default fallback value;
    }

The following method works in IE11+, Firefox 25+ and Chrome 30+:

        if(window.navigator.msSaveOrOpenBlob) {
            var fileData = [str];
            blobObject = new Blob(fileData);
            $(anchorSelector).click(function(){
                window.navigator.msSaveOrOpenBlob(blobObject, fileName);
            });
        } else {
            var url = "data:text/plain;charset=utf-8," + encodeURIComponent(str);
            $(anchorSelector).attr("download", fileName);               
            $(anchorSelector).attr("href", url);
        }
    }

    $(function () {
        var str = "hi,file";
        createDownloadLink("#export",str,"file.txt");

Firefox and Chrome support data URI for navigation, which allows us to create files by navigating to a data URI, while IE doesn't support it for security purposes.

On the other hand, IE has API for saving a blob, which can be used to create and download files.

Dockers use images which are build in layers. This adds a lot in terms of portability, sharing, versioning and other features. These images are very easy to port or transfer and since they are in layers, changes in subsequent versions are added in form of layers over previous layers. So, while porting many a times you don't need to port the base layers. Dockers have containers which run these images with execution environment contained, they add changes as new layers providing easy version control.

Apart from that Docker Hub is a good registry with thousands of public images, where you can find images which have OS and other softwares installed. So, you can get a pretty good head start for your application.

If you're modifying your class to accept a Stream instead of a filename, don't bother converting to a MemoryStream. Let the underlying Stream handle the operations:

public class MyClass
{ 
    Stream _s;

    public MyClass(Stream s) { _s = s; }
}

But if you really need a MemoryStream for internal operations, you'll have to copy the data out of the source Stream into the MemoryStream:

public MyClass(Stream stream)
{
    _ms = new MemoryStream();
    CopyStream(stream, _ms);
}

// Merged From linked CopyStream below and Jon Skeet's ReadFully example
public static void CopyStream(Stream input, Stream output)
{
    byte[] buffer = new byte[16*1024];
    int read;
    while((read = input.Read (buffer, 0, buffer.Length)) > 0)
    {
        output.Write (buffer, 0, read);
    }
}

Swift 4.X and Xcode 10

let lbl = UILabel(frame: CGRect(x: 10, y: 50, width: 230, height: 21))
lbl.textAlignment = .center //For center alignment
lbl.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..."
lbl.textColor = .white
lbl.backgroundColor = .lightGray//If required
lbl.font = UIFont.systemFont(ofSize: 17)

//To display multiple lines in label
lbl.numberOfLines = 0 //If you want to display only 2 lines replace 0(Zero) with 2.
lbl.lineBreakMode = .byWordWrapping //Word Wrap
// OR
lbl.lineBreakMode = .byCharWrapping //Charactor Wrap

lbl.sizeToFit()//If required
yourView.addSubview(lbl)

If you have multiple labels in your class use extension to add properties.

//Label 1
let lbl1 = UILabel(frame: CGRect(x: 10, y: 50, width: 230, height: 21))
lbl1.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..."
lbl1.myLabel()//Call this function from extension to all your labels
view.addSubview(lbl1)

//Label 2
let lbl2 = UILabel(frame: CGRect(x: 10, y: 150, width: 230, height: 21))
lbl2.text = "This is my label fdsjhfg sjdg dfgdfgdfjgdjfhg jdfjgdfgdf end..."
lbl2.myLabel()//Call this function from extension to all your labels
view.addSubview(lbl2)

extension UILabel {
    func myLabel() {
        textAlignment = .center
        textColor = .white
        backgroundColor = .lightGray
        font = UIFont.systemFont(ofSize: 17)
        numberOfLines = 0
        lineBreakMode = .byCharWrapping
        sizeToFit()
    }
}

Worked for me in angular 4

by adding style="margin:0 auto;"

<mat-progress-spinner
  style="margin:0 auto;"
  *ngIf="isLoading"
  mode="indeterminate">
  </mat-progress-spinner>

The correct one is :

int factorial(int n)
{
    if(n==0||n==1)
        return 1;
    else 
        return n*factorial(n-1);
}

This would return 1 for factorial 0. Do it believe me . I have learned this the hard way. Just for not keeping the condition for 0 could not clear an interview.

ASCII isn't in it any more. Using UTF-8 encoding means that you aren't using ASCII encoding. What you should use the escaping mechanism for is what the RFC says:

All Unicode characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark, reverse solidus, and the control characters (U+0000 through U+001F)

The printStackTrace() helps the programmer understand where the actual problem occurred. The printStackTrace() method is a member of the class Throwable in the java.lang package.

Yes this does work in PostgreSQL (assuming the column "date" is of datatype date) Why don't you just try it?

The standard ANSI SQL format would be:

SELECT Table.date 
FROM Table 
WHERE date > current_date - interval '10' day;

I prefer that format as it makes things easier to read (but it is the same as current_date - 10).

Thanks to many of the answers above and elsewhere, this was my solution to a similar problem to the OP. The problem for me was creating a button in Word that asks the user for a network address, and pulls up the LAN resources in an Explorer window.

Untouched, the code would take you to \\10.1.1.1\Test, so edit as you see fit. I'm just a monkey on a keyboard, here, so all comments and suggestions are welcome.

Private Sub CommandButton1_Click()
    Dim ipAddress As Variant
    On Error GoTo ErrorHandler

    ipAddress = InputBox("Please enter the IP address of the network resource:", "Explore a network resource", "\\10.1.1.1")
    If ipAddress <> "" Then
        ThisDocument.FollowHyperlink ipAddress & "\Test"
    End If

    ExitPoint:
        Exit Sub

    ErrorHandler:
        If Err.Number = "4120" Then
            GoTo ExitPoint
        ElseIf Err.Number = "4198" Then
            MsgBox "Destination unavailable"
            GoTo ExitPoint
        End If

        MsgBox "Error " & Err.Number & vbCrLf & Err.Description
        Resume ExitPoint

End Sub

The only fix that really worked for me was uninstalling Java 7 and installing Java 6 on my Windows 8 x64 based machine.

You can download Java 6 from here.

My particular use-case was selecting a text range inside an editable span element, which, as far as I could see, is not described in any of the answers here.

The main difference is that you have to pass a node of type Text to the Range object, as described in the documentation of Range.setStart():

If the startNode is a Node of type Text, Comment, or CDATASection, then startOffset is the number of characters from the start of startNode. For other Node types, startOffset is the number of child nodes between the start of the startNode.

The Text node is the first child node of a span element, so to get it, access childNodes[0] of the span element. The rest is the same as in most other answers.

Here a code example:

var startIndex = 1;
var endIndex = 5;
var element = document.getElementById("spanId");
var textNode = element.childNodes[0];

var range = document.createRange();
range.setStart(textNode, startIndex);
range.setEnd(textNode, endIndex);

var selection = window.getSelection();
selection.removeAllRanges();
selection.addRange(range);

Other relevant documentation:

I made a video on youTube
Scroll StackViews using only Storyboard in Xcode

I think 2 kind of scenarios can appear here.

The view inside the scrollView -

1. does not have any intrinsic content Size (e.g UIView)
2. does have its own intrinsic content Size (e.g UIStackView)

For a vertically scrollable view in both cases you need to add these constraints:

1. 4 constraints from top, left, bottom and right.

2. Equal width to scrollview (to stop scrolling horizontally)

You don't need any other constraints for views which have his own intrinsic content height.

For views which do not have any intrinsic content height, you need to add a height constraint. The view will scroll only if the height constraint is more than the height of the scrollView.

Option 1

There is a solution that works with some versions of awk:

awk '{ $(NF+1)=$1;$1="";$0=$0;} NF=NF ' infile.txt

Explanation:

       $(NF+1)=$1                          # add a new field equal to field 1.
                  $1=""                    # erase the contents of field 1.
                        $0=$0;} NF=NF      # force a re-calc of fields.
                                           # and use NF to promote a print.

Result:

United Arab Emirates AE
Antigua & Barbuda AG
Netherlands Antilles AN
American Samoa AS
Bosnia and Herzegovina BA
Burkina Faso BF
Brunei Darussalam BN

However that might fail with older versions of awk.

Option 2

awk '{ $(NF+1)=$1;$1="";sub(OFS,"");}1' infile.txt

That is:

awk '{                                      # call awk.
       $(NF+1)=$1;                          # Add one trailing field.
                  $1="";                    # Erase first field.
                        sub(OFS,"");        # remove leading OFS.
                                    }1'     # print the line.

Note that what needs to be erased is the OFS, not the FS. The line gets re-calculated when the field $1 is asigned. That changes all runs of FS to one OFS.

But even that option still fails with several delimiters, as is clearly shown by changing the OFS:

awk -v OFS=';' '{ $(NF+1)=$1;$1="";sub(OFS,"");}1' infile.txt

That line will output:

United;Arab;Emirates;AE
Antigua;&;Barbuda;AG
Netherlands;Antilles;AN
American;Samoa;AS
Bosnia;and;Herzegovina;BA
Burkina;Faso;BF
Brunei;Darussalam;BN

That reveals that runs of FS are being changed to one OFS.
The only way to avoid that is to avoid the field re-calculation.
One function that can avoid re-calc is sub.
The first field could be captured, then removed from $0 with sub, and then both re-printed.

Option 3

awk '{ a=$1;sub("[^"FS"]+["FS"]+",""); print $0, a;}' infile.txt
       a=$1                                   # capture first field.
       sub( "                                 # replace: 
             [^"FS"]+                         # A run of non-FS
                     ["FS"]+                  # followed by a run of FS.
                            " , ""            # for nothing.
                                  )           # Default to $0 (the whole line.
       print $0, a                   # Print in reverse order, with OFS.


United Arab Emirates AE
Antigua & Barbuda AG
Netherlands Antilles AN
American Samoa AS
Bosnia and Herzegovina BA
Burkina Faso BF
Brunei Darussalam BN

Even if we change the FS, the OFS and/or add more delimiters, it works.
If the input file is changed to:

AE..United....Arab....Emirates
AG..Antigua....&...Barbuda
AN..Netherlands...Antilles
AS..American...Samoa
BA..Bosnia...and...Herzegovina
BF..Burkina...Faso
BN..Brunei...Darussalam

And the command changes to:

awk -vFS='.' -vOFS=';' '{a=$1;sub("[^"FS"]+["FS"]+",""); print $0,a;}' infile.txt

The output will be (still preserving delimiters):

United....Arab....Emirates;AE
Antigua....&...Barbuda;AG
Netherlands...Antilles;AN
American...Samoa;AS
Bosnia...and...Herzegovina;BA
Burkina...Faso;BF
Brunei...Darussalam;BN

The command could be expanded to several fields, but only with modern awks and with --re-interval option active. This command on the original file:

awk -vn=2 '{a=$1;b=$2;sub("([^"FS"]+["FS"]+){"n"}","");print $0,a,b;}' infile.txt

Will output this:

Arab Emirates AE United
& Barbuda AG Antigua
Antilles AN Netherlands
Samoa AS American
and Herzegovina BA Bosnia
Faso BF Burkina
Darussalam BN Brunei

It sounds like you're looking for applicationHost.config, which is located in C:\Windows\System32\inetsrv\config.

Yes, it's an XML file, and yes, editing the file by hand will affect the IIS config after a restart. You can think of IIS Manager as a GUI front-end for editing applicationHost.config and web.config.

I hope this code will help you.

Selecting 'Banana' from a dropdown

1. Using the index of dropdown

ddelement.select_by_index(1)

2. Using the value of dropdown

ddelement.select_by_value('1')

3. You can use match the text which is displayed in the drop down.

Here is all you need:

new HtmlWebpackPlugin({
    favicon: "./src/favicon.gif"
})

That is definitely after adding "favicon.gif" to the folder "src".

This will transfer the icon to your build folder and include it in your tag like this <link rel="shortcut icon" href="favicon.gif">. This is safer than just importing with copyWebpackPLugin

You can set timeout like this,

con.setConnectTimeout(connectTimeout);
con.setReadTimeout(socketTimeout);

I had the same issue, and it appears Gidon's answer has one tiny flaw: it generates a relative URL, which cannot be sent by mail.

My solution looks like this:

string link = HttpContext.Request.Url.Scheme + "://" + HttpContext.Request.Url.Authority + Url.Action("ResetPassword", "Account", new { key = randomString });

This way, a full URL is generated, and it works even if the application is several levels deep on the hosting server, and uses a port other than 80.

EDIT: I found this useful as well.

Well I am not sure what actual cause is but I have done this way for the same error. I have comment out this annotation for the servelet and its working.

//@WebServlet("/HelloWorld")
public class HelloWorld extends HttpServlet {

Dont know that could be proper solution of not. but this worked and another thing that can be test is add servlet jar into class path. That might work.

There seem to be differences between the two ways to access a git repository i.e. using either SSH or HTTPS. For me, I encountered the error because I was trying to push my local repository using SSH.

The problem can simply be solved by clicking the clone button on the landing page of your project and the copying the HTTPS link and replacing it to the SSH link appearing with the format "git@gitlab...".

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

When passing by ref you are basically passing a pointer to the variable. Pass by value you are passing a copy of the variable. In basic usage this normally means pass by ref changes to the variable will seen be the calling method and pass by value they wont.

If @Maleki's answer isn't working for you, check and see if you have an .editorconfig file in your project folder.

For example the Angular CLI generates one with a new project that looks like this

# Editor configuration, see http://editorconfig.org
root = true

[*]
charset = utf-8
indent_style = space
indent_size = 2
insert_final_newline = true
trim_trailing_whitespace = true

[*.md]
max_line_length = off
trim_trailing_whitespace = false

Changing the indent_size here is required as it seems it will override anything in your .vscode workspace or user settings.

Firefox 13+ provides an experimental implementation of the map object similar to the dict object in python. Specifications here.

It's only avaible in firefox, but it looks better than using attributes of a new Object(). Citation from the documentation :

• An Object has a prototype, so there are default keys in the map. However, this can be bypassed using map = Object.create(null).
• The keys of an Object are Strings, where they can be any value for a Map.
• You can get the size of a Map easily while you have to manually keep track of size for an Object.

Try closing and reopening the file, then press Ctrl+F11.

Verify that the name of the file you are running is the same as the name of the project you are working in, and that the name of the public class in that file is the same as the name of the project you are working in as well.

Otherwise, restart Eclipse. Let me know if this solves the problem! Otherwise, comment, and I'll try and help.

    session_start();
    if(isset($_SESSION['current'])){
         $_SESSION['oldlink']=$_SESSION['current'];
    }else{
         $_SESSION['oldlink']='no previous page';
    }
    $_SESSION['current']=$_SERVER['PHP_SELF'];

Maybe this is what you're looking for? It will remember the old link/page you're coming from (within your website).

Put that piece on top of each page.

If you want to make it 'refresh proof' you can add another check:

   if(isset($_SESSION['current']) && $_SESSION['current']!=$_SERVER['PHP_SELF'])

This will make the page not remember itself.

UPDATE: Almost the same as @Brandon though... Just use a php variable, I know this looks like a security risk, but when done correct it isn't.

 <a href="home.php?a=register">Register Now!</a>

PHP:

 if(isset($_GET['a']) /*you can validate the link here*/){
    $_SESSION['link']=$_GET['a'];
 }

Why even store the GET in a session? Just use it. Please tell me why you do not want to use GET. « Validate for more security. I maybe can help you with a better script.

To suppress the page number on the first page, add \thispagestyle{empty} after the \maketitle command.

The second page of the document will then be numbered "2". If you want this page to be numbered "1", you can add \pagenumbering{arabic} after the \clearpage command, and this will reset the page number.

Here's a complete minimal example:

\documentclass[notitlepage]{article}

\title{My Report}
\author{My Name}

\begin{document}
\maketitle
\thispagestyle{empty}

\begin{abstract}
\ldots
\end{abstract}

\clearpage
\pagenumbering{arabic} 

\section{First Section}
\ldots

\end{document}

There is a condition that most of these solutions do not address. I revised Patrick Honorez's solution to handle it. I felt I had to share this because I was pulling my hair out when the original function was occasionally clearing more data that I expected.

The situation happens when the table only has one column and the .SpecialCells(xlCellTypeConstants).ClearContents attempts to clear the contents of the top row. In this situation, only one cell is selected (the top row of the table that only has one column) and the SpecialCells command applies to the entire sheet instead of the selected range. What was happening to me was other cells on the sheet that were outside of my table were also getting cleared.

I did some digging and found this advice from Mathieu Guindon: Range SpecialCells ClearContents clears whole sheet

Range({any single cell}).SpecialCells({whatever}) seems to work off the entire sheet.

Range({more than one cell}).SpecialCells({whatever}) seems to work off the specified cells.

If the list/table only has one column (in row 1), this revision will check to see if the cell has a formula and if not, it will only clear the contents of that one cell.

@Waisky suggested:

You need to use setInterval to trigger the change, but you also need to clear the timer when the component unmounts to prevent it leaving errors and leaking memory:

If you'd like to do the same thing, using Hooks:

const [time, setTime] = useState(Date.now());

useEffect(() => {
  const interval = setInterval(() => setTime(Date.now()), 1000);
  return () => {
    clearInterval(interval);
  };
}, []);

Regarding the comments:

You don't need to pass anything inside []. If you pass time in the brackets, it means run the effect every time the value of time changes, i.e., it invokes a new setInterval every time, time changes, which is not what we're looking for. We want to only invoke setInterval once when the component gets mounted and then setInterval calls setTime(Date.now()) every 1000 seconds. Finally, we invoke clearInterval when the component is unmounted.

Note that the component gets updated, based on how you've used time in it, every time the value of time changes. That has nothing to do with putting time in [] of useEffect.

origin/master is an entity (since it is not a physical branch) representing the state of the master branch on the remote origin.

origin master is the branch master on the remote origin.

So we have these:

• origin/master ( A representation or a pointer to the remote branch)
• master - (actual branch)
• <Your_local_branch> (actual branch)
• <Your_local_branch4> (actual branch)
• <Your_local_branch4> (actual branch)

Example (in local branch master):

git fetch # get current state of remote repository
git merge origin/master # merge state of remote master branch into local branch
git push origin master # push local branch master to remote branch master

As mklement0 points out, a feature for listing all Makefile targets is missing from GNU-make, and his answer and others provides ways to do this.

However, the original post also mentions rake, whose tasks switch does something slightly different than just listing all tasks in the rakefile. Rake will only give you a list of tasks that have associated descriptions. Tasks without descriptions will not be listed. This gives the author the ability to both provide customized help descriptions and also omit help for certain targets.

If you want to emulate rake's behavior, where you provide descriptions for each target, there is a simple technique for doing this: embed descriptions in comments for each target you want listed.

You can either put the description next to the target or, as I often do, next to a PHONY specification above the target, like this:

.PHONY: target1 # Target 1 help text
target1: deps
    [... target 1 build commands]

.PHONY: target2 # Target 2 help text
target2:
    [... target 2 build commands]

...                                                                                                         

.PHONY: help # Generate list of targets with descriptions                                                                
help:                                                                                                                    
    @grep '^.PHONY: .* #' Makefile | sed 's/\.PHONY: \(.*\) # \(.*\)/\1 \2/' | expand -t20

Which will yield

$ make help
target1             Target 1 help text
target2             Target 2 help text

...
help                Generate list of targets with descriptions

You can also find a short code example in this gist and here too.

Again, this does not solve the problem of listing all the targets in a Makefile. For example, if you have a big Makefile that was maybe generated or that someone else wrote, and you want a quick way to list its targets without digging through it, this won't help.

However, if you are writing a Makefile, and you want a way to generate help text in a consistent, self-documenting way, this technique may be useful.

You can include a .js file which has the script to set the

window.location.href = url;

Where url would be the url you wish to load.

CSS:

.reverse {
  transform: rotate(180deg);
}

.rotate {
  animation-duration: .5s;
  animation-iteration-count: 1;
  animation-name: yoyo;
  animation-timing-function: linear;
}

@keyframes yoyo {
  from { transform: rotate(  0deg); }
  to   { transform: rotate(360deg); }
}

Javascript:

$(buttonElement).click(function () {
  $(".arrow").toggleClass("reverse")

  return false
})

$(buttonElement).hover(function () {
  $(".arrow").addClass("rotate")
}, function() {
  $(".arrow").removeClass("rotate")
})

• Short version of (correct) tzaman answer will be (for fresh SVN)

  svn switch ^/branches/v1p2p3
  

• --relocate switch is deprecated anyway, when it needed you'll have to use svn relocate command

• Instead of creating snapshot-branch (ReadOnly) you can use tags (conventional RO labels for history)

On Windows, the caret character (^) must be escaped:

svn switch ^^/branches/v1p2p3

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

Polish-> English (VS on MAC) answer: When I started a project and was forced to download Visual Studio, went to their page and saw that Microsoft logo I knew there would be problems... And here it is. It occurred difficult to change the language of VS on Mac. My OS is purely English and only because of the fact I downloaded it using a browser with Polish set as a default language I got the wrong version. I had to reinstall the version to the newest and then Visual Studio Community -> Preferences(in the environment section) -> Visual Style-> User Interface Language.

It translates to polish: Visual Studio Community -> Preferencje -> Styl Wizualny w sekcji Srodowisko -> Jezyk interfejsu uzytkownika -> English.

If you don't see such an option then, as I was, you are forced to upgrade this crappy VS to the newest version.

In your custom array adapter, you override the getView() method, as you presumably familiar with. Then all you have to do is use a switch statement or an if statement to return a certain custom View depending on the position argument passed to the getView method. Android is clever in that it will only give you a convertView of the appropriate type for your position/row; you do not need to check it is of the correct type. You can help Android with this by overriding the getItemViewType() and getViewTypeCount() methods appropriately.

I had the same problem. The solution for me was the order of super.onCreate and setContentView within the FragmentActivity

Following order works fine:

    super.onCreate(savedInstanceState);
    setContentView(R.layout.fc_activity_list_profiles);

None of these fixes worked for my develop platform targeting SDK 16, Release 4.1.2, so I found a workaround.

caronte ("https://www.secure-example.com/page.php");

function caronte($url) {
    // build curl request
    $ch = curl_init();
    foreach ($_POST as $a => $b) {
        $post[htmlentities($a)]=htmlentities($b);
    }
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,http_build_query($post));

    // receive server response ...
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $server_output = curl_exec ($ch);
    curl_close ($ch);

    echo $server_output;
}

?>

Why not using PixelRatio.getPixelSizeForLayoutSize(/* size in dp */);, it's just the same as pd units in Android.

You want to do this:

git add -u
git reset HEAD path/to/file
git commit

Be sure and do this from the top level of the repo; add -u adds changes in the current directory (recursively).

The key line tells git to reset the version of the given path in the index (the staging area for the commit) to the version from HEAD (the currently checked-out commit).

And advance warning of a gotcha for others reading this: add -u stages all modifications, but doesn't add untracked files. This is the same as what commit -a does. If you want to add untracked files too, use add . to recursively add everything.

If you are using Bootstrap 3.3.x then use this code (you need to add class name carousel-fade to your carousel).

.carousel-fade .carousel-inner .item {
  -webkit-transition-property: opacity;
          transition-property: opacity;
}
.carousel-fade .carousel-inner .item,
.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  opacity: 0;
}
.carousel-fade .carousel-inner .active,
.carousel-fade .carousel-inner .next.left,
.carousel-fade .carousel-inner .prev.right {
  opacity: 1;
}
.carousel-fade .carousel-inner .next,
.carousel-fade .carousel-inner .prev,
.carousel-fade .carousel-inner .active.left,
.carousel-fade .carousel-inner .active.right {
  left: 0;
  -webkit-transform: translate3d(0, 0, 0);
          transform: translate3d(0, 0, 0);
}
.carousel-fade .carousel-control {
  z-index: 2;
}

Of course you can write "something" a bit better to keep maintenance:

#include <iostream>
#include <cstdlib>

using namespace std;

class Something
{
    public:
        Something(int x, int y, int z) : a(x), b(y), c(z) { }
        int a;
        int b;
        int c;

        friend ostream& operator<<(ostream&, const Something&);

        void print() const { printf("%i, %i, %i\n", a, b, c); }
};

ostream& operator<<(ostream& o, const Something& s)
{
    o << s.a << ", " << s.b << ", " << s.c;
    return o;
}

int main(void)
{
    Something s(3, 2, 1);

    // Output with printf
    s.print(); // Simple as well, isn't it?

    // Output with cout
    cout << s << endl;

    return 0;
}

And a bit extended test of cout vs. printf, added a test of 'double', if anyone wants to do more testing (Visual Studio 2008, release version of the executable):

#include <stdio.h>
#include <iostream>
#include <ctime>

class TimedSection {
    char const *d_name;
    //timespec d_start;
    clock_t d_start;

    public:
        TimedSection(char const *name) :
            d_name(name)
        {
            //clock_gettime(CLOCK_REALTIME, &d_start);
            d_start = clock();
        }
        ~TimedSection() {
            clock_t end;
            //clock_gettime(CLOCK_REALTIME, &end);
            end = clock();
            double duration = /*1e3 * (end.tv_sec - d_start.tv_sec) +
                              1e-6 * (end.tv_nsec - d_start.tv_nsec);
                              */
                              (double) (end - d_start) / CLOCKS_PER_SEC;

            std::cerr << d_name << '\t' << std::fixed << duration * 1000.0 << " ms\n";
        }
};


int main() {
    const int iters = 1000000;
    char const *text = "01234567890123456789";
    {
        TimedSection s("cout with only endl");
        for (int i = 0; i < iters; ++i)
            std::cout << std::endl;
    }
    {
        TimedSection s("cout with only '\\n'");
        for (int i = 0; i < iters; ++i)
            std::cout << '\n';
    }
    {
        TimedSection s("printf with only '\\n'");
        for (int i = 0; i < iters; ++i)
            printf("\n");
    }
    {
        TimedSection s("cout with string constant and endl");
        for (int i = 0; i < iters; ++i)
            std::cout << "01234567890123456789" << std::endl;
    }
    {
        TimedSection s("cout with string constant and '\\n'");
        for (int i = 0; i < iters; ++i)
            std::cout << "01234567890123456789\n";
    }
    {
        TimedSection s("printf with string constant and '\\n'");
        for (int i = 0; i < iters; ++i)
            printf("01234567890123456789\n");
    }
    {
        TimedSection s("cout with some stuff and endl");
        for (int i = 0; i < iters; ++i)
            std::cout << text << "01234567890123456789" << i << std::endl;
    }
    {
        TimedSection s("cout with some stuff and '\\n'");
        for (int i = 0; i < iters; ++i)
            std::cout << text << "01234567890123456789" << i << '\n';
    }
    {
        TimedSection s("printf with some stuff and '\\n'");
        for (int i = 0; i < iters; ++i)
            printf("%s01234567890123456789%i\n", text, i);
    }
    {
        TimedSection s("cout with formatted double (width & precision once)");
        std::cout << std::fixed << std::scientific << std::right << std::showpoint;
        std::cout.width(8);
        for (int i = 0; i < iters; ++i)
            std::cout << text << 8.315 << i << '\n';
    }
    {
        TimedSection s("cout with formatted double (width & precision on each call)");
        std::cout << std::fixed << std::scientific << std::right << std::showpoint;

        for (int i = 0; i < iters; ++i)
            { std::cout.width(8);
              std::cout.precision(3);
              std::cout << text << 8.315 << i << '\n';
            }
    }
    {
        TimedSection s("printf with formatted double");
        for (int i = 0; i < iters; ++i)
            printf("%8.3f%i\n", 8.315, i);
    }
}

The result is:

cout with only endl    6453.000000 ms
cout with only '\n'    125.000000 ms
printf with only '\n'    156.000000 ms
cout with string constant and endl    6937.000000 ms
cout with string constant and '\n'    1391.000000 ms
printf with string constant and '\n'    3391.000000 ms
cout with some stuff and endl    9672.000000 ms
cout with some stuff and '\n'    7296.000000 ms
printf with some stuff and '\n'    12235.000000 ms
cout with formatted double (width & precision once)    7906.000000 ms
cout with formatted double (width & precision on each call)    9141.000000 ms
printf with formatted double    3312.000000 ms

For SQL Server, CROSS JOIN and FULL OUTER JOIN are different. CROSS JOIN is simply Cartesian Product of two tables, irrespective of any filter criteria or any condition.

FULL OUTER JOIN gives unique result set of LEFT OUTER JOIN and RIGHT OUTER JOIN of two tables. It also needs ON clause to map two columns of tables.

Table 1 contains 10 rows and Table 2 contains 20 rows with 5 rows matching on specific columns.

Then CROSS JOIN will return 10*20=200 rows in result set.

FULL OUTER JOIN will return 25 rows in result set.

FULL OUTER JOIN (or any other JOIN) always returns result set with less than or equal to Cartesian Product number.

Number of rows returned by FULL OUTER JOIN equal to (No. of Rows by LEFT OUTER JOIN) + (No. of Rows by RIGHT OUTER JOIN) - (No. of Rows by INNER JOIN).

I've used this before to setup a query against another server and db via linked server:

EXEC sp_addlinkedserver @server='PWA_ProjectServer', @srvproduct='',
@provider='SQLOLEDB', @datasrc='SERVERNAME\PWA_ProjectServer'

per the comment above:

select * from [server].[database].[schema].[table]

e.g.

select top 6 * from [PWA_ProjectServer].[PWA_ProjectServer_Reporting].[dbo].[MSP_AdminStatus]

That's something controlled by your terminal, not by printf.

printf simply sends a \t to the output stream (which can be a tty, a file etc), it doesn't send a number of spaces.
