Programs & Examples On #Pocket ie

Same functionality I prefer than using much heavy jQuery mobile is Carousel Swipe. I suggest directly jump in to source code on github, and copy file carousel-swipe.js in to your project directory.

Use swiper events as bellow:

$('#carousel-example-generic').carousel({
      interval: false 
  });

To remove element from array is easy just do the following

let array_splited = [].split('/');
array_splited.pop()
array_splited.join('/')

If you are on Unix, you could use the access time of the files in there. Just enable access time for your filesystem, then run a clean build of all your projects you would like to keep dependencies for and then do something like this (UNTESTED!):

find ~/.m2 -amin +5 -iname '*.pom' | while read pom; do parent=`dirname "$pom"`; rm -Rf "$parent"; done

This will find all *.pom files which have last been accessed more than 5 minutes ago (assuming you started your builds max 5 minutes ago) and delete their directories.

Add "echo " before the rm to do a 'dry-run'.

Another regex solution:

string.replace(/\D/g,'');  //remove the non-Numeric

Similarly, you can

string.replace(/\W/g,'');  //remove the non-alphaNumeric

In RegEX, the symbol '\' would make the letter following it a template: \w -- alphanumeric, and \W - Non-AlphaNumeric, negates when you capitalize the letter.

Open Oracle SQLDeveloper

Right click on connection tab and select new connection

Enter HR_ORCL in connection name and HR for the username and password.

Specify localhost for your Hostname and enter ORCL for the SID.

Click Test.

The status of the connection Test Successfully.

The connection was not saved however click on Save button to save the connection. And then click on Connect button to connect your database.

The connection is saved and you see the connection list.

try this

I just added the project of google services and added a reference in my project property->Android

import java.io.IOException;

class ExamTest{

    public static void main(String args[]) throws IOException{
        int sn=System.in.read();
        System.out.println(sn);
    }
}

If you want get char input you have to cast like this: char sn=(char) System.in.read()

The value byte is returned as int in the range 0 to 255. However, unlike in other languages’ methods, System.in.read() reads only a byte at a time.

Trying this out on Windows 10, none of the command-line instructions worked.

Right clicking on "Computer" then open Properties etc. as the post by Galen Nare above already explains, leads you to a window where you need to click on "new" and then paste the path (as said: without deleting anything else). Afterwards you can check by typing java -version in the command-line window, which should display your current java version, if everything worked out right.

Update the data ... change button titles..whatever stuff you have to update..

then just call

[self.view setNeedsDisplay];

Add given code Service class for "OS >= Build.VERSION_CODES.O" in onCreate()

@Override
public void onCreate(){
    super.onCreate();

     .................................
     .................................

    //For creating the Foreground Service
    NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    String channelId = Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? getNotificationChannel(notificationManager) : "";
    NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId);
    Notification notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.ic_launcher)
           // .setPriority(PRIORITY_MIN)
            .setCategory(NotificationCompat.CATEGORY_SERVICE)
            .build();

    startForeground(110, notification);
}



@RequiresApi(Build.VERSION_CODES.O)
private String getNotificationChannel(NotificationManager notificationManager){
    String channelId = "channelid";
    String channelName = getResources().getString(R.string.app_name);
    NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
    channel.setImportance(NotificationManager.IMPORTANCE_NONE);
    channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
    notificationManager.createNotificationChannel(channel);
    return channelId;
}

Add this permission in manifest file:

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

You can use JQuery .load() method:

http://api.jquery.com/load/

 $( "#content" ).load( "ajax/test.html div#content" );

You need the Business Intelligence Studio ..I've checked and my version of VS2008 Pro doesn't have them installed.

To remove error from eclipse for android there are few steps:-

1.open eclipse check all the error

2.In search tab open SDK manager

3.Remove all the value show as error in eclipse

4.After remove from sdk restart eclipse

I had the same problem... I had to run it as a user.

00 * * * * root /usr/bin/php /var/virtual/hostname.nz/public_html/cronjob.php

exit(X), where X is a number (according to the doc) should work. But it is not recommended by Apple and won't be accepted by the AppStore. Why? Because of these guidelines (one of my app got rejected):

We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines.

Please refer to the attached screenshot/s for reference.

The iOS Human Interface Guidelines specify,

"Always Be Prepared to Stop iOS applications stop when people press the Home button to open a different application or use a device feature, such as the phone. In particular, people don’t tap an application close button or select Quit from a menu. To provide a good stopping experience, an iOS application should:

Save user data as soon as possible and as often as reasonable because an exit or terminate notification can arrive at any time.

Save the current state when stopping, at the finest level of detail possible so that people don’t lose their context when they start the application again. For example, if your app displays scrolling data, save the current scroll position."

> It would be appropriate to remove any mechanisms for quitting your app.

Plus, if you try to hide that function, it would be understood by the user as a crash.

For those who may need this info:

I figured out that you can pretty much run a command that's in your PATH from a PS script, and it should work.

Sometimes you may have to pre-launch this command with cmd.exe /c

Examples

Calling git from a PS script

I had to repackage a git client wrapped in Chocolatey (for those who may not know, it's a kind of app-store for Windows) which massively uses PS scripts.

I found out that, once git is in the PATH, commands like

$ca_bundle = git config --get http.sslCAInfo

will store the location of git crt file in $ca_bundle variable.

Looking for an App

Another example that is a combination of the present SO post and this SO post is the use of where command

$java_exe = cmd.exe /c where java

will store the location of java.exe file in $java_exe variable.

Do you mean like:

$val1 = rand( 1, 10 ); // gives one integer between 1 and 10
$val2 = rand( 20, 40 ) ; // gives one integer between 20 and 40

or perhaps:

$range = range( 1, 10 ); // gives array( 1, 2, ..., 10 );
$range2 = range( 20, 40 ); // gives array( 20, 21, ..., 40 );

or maybe:

$truth1 = $val >= 1 && $val <= 10; // true if 1 <= x <= 10
$truth2 = $val >= 20 && $val <= 40; // true if 20 <= x <= 40

suppose you wanted:

$in_range = ( $val > 1 && $val < 10 ) || ( $val > 20 && $val < 40 ); // true if 1 < x < 10 OR 20 < x < 40

if you want to use truncate use this:

SET FOREIGN_KEY_CHECKS = 0; 
TRUNCATE table $table_name; 
SET FOREIGN_KEY_CHECKS = 1;

You can try this way also,

Html:

<form action="javascript:next()" method="post">
<input type="submit" value=Submit /></form>

Javascript:

      function next(){
        //Location where you want to forward your values
        window.location.href = "http://localhost:8563/And/try1.jsp?dymanicValue=" + values; 
        }

None of the following answers are right. All these methods just seem to be alike, but in practice do absolutely different things. It is hard to give short comments. Better to give a link to full documentation about these methods: http://docs.jboss.org/hibernate/core/3.6/reference/en-US/html/objectstate.html

Try this. It is in VB.net and you need to convert it to Javascript. This function accepts parameters in decimal minutes.

    Private Function calculateDistance(ByVal long1 As String, ByVal lat1 As String, ByVal long2 As String, ByVal lat2 As String) As Double

remove partition by and add group by clause,

SELECT BrandId
      ,SUM(ICount) totalSum
  FROM Table 
WHERE DateId  = 20130618
GROUP BY BrandId

import json
data = json.dumps(list)
print(data)

The above code snippet should work.

As @Alex McMillan mentioned, use state to dictate what should be rendered in the dom.

In the example below I have an input field and I want to add a second one when the user clicks the button, the onClick event handler calls handleAddSecondInput( ) which changes inputLinkClicked to true. I am using a ternary operator to check for the truthy state, which renders the second input field

class HealthConditions extends React.Component {
  constructor(props) {
    super(props);


    this.state = {
      inputLinkClicked: false
    }
  }

  handleAddSecondInput() {
    this.setState({
      inputLinkClicked: true
    })
  }


  render() {
    return(
      <main id="wrapper" className="" data-reset-cookie-tab>
        <div id="content" role="main">
          <div className="inner-block">

            <H1Heading title="Tell us about any disabilities, illnesses or ongoing conditions"/>

            <InputField label="Name of condition"
              InputType="text"
              InputId="id-condition"
              InputName="condition"
            />

            {
              this.state.inputLinkClicked?

              <InputField label=""
                InputType="text"
                InputId="id-condition2"
                InputName="condition2"
              />

              :

              <div></div>
            }

            <button
              type="button"
              className="make-button-link"
              data-add-button=""
              href="#"
              onClick={this.handleAddSecondInput}
            >
              Add a condition
            </button>

            <FormButton buttonLabel="Next"
              handleSubmit={this.handleSubmit}
              linkto={
                this.state.illnessOrDisability === 'true' ?
                "/404"
                :
                "/add-your-details"
              }
            />

            <BackLink backLink="/add-your-details" />

          </div>
         </div>
      </main>
    );
  }
}

If it is an Angular application you can simply do this

input.ng-invalid.ng-touched
{
    border: 1px solid red !important; 
}

select T.object_id, T.name, I.indid, I.rows 
  from Sys.tables T 
  left join Sys.sysindexes I 
    on (I.id = T.object_id and (indid =1 or indid =0 ))
 where T.type='U'

Here indid=1 means a CLUSTERED index and indid=0 is a HEAP

The above mentioned comments are very useful but they are a bit difficult to implement. Below steps you can try, I also tried it and it worked:

1. Download that file from your notebook in PY file format (You can find that option in File tab).
2. Now copy that downloaded file into the working directory of Jupyter Notebook
3. You are now ready to use it. Just import .PY File into the ipynb file

Yes, there's a command git commit --amend which is used to "fix" last commit.

In your case it would be called as:

git add the_left_out_file
git commit --amend --no-edit

The --no-edit flag allow to make amendment to commit without changing commit message.

EDIT: Warning You should never amend public commits, that you already pushed to public repository, because what amend does is actually removing from history last commit and creating new commit with combined changes from that commit and new added when amending.

Instead of modifying the height and width attributes of the image, try modifying the CSS height and width.

myimg = document.getElementById('myimg');
myimg.style.height = "50px";
myimg.style.width = "50px";

One common "gotcha" is that the height and width styles are strings that include a unit, like "px" in the example above.

Edit - I think that setting the height and width directly instead of using style.height and style.width should work. It would also have the advantage of already having the original dimensions. Can you post a bit of your code? Are you sure you're in standards mode instead of quirks mode?

This should work:

myimg = document.getElementById('myimg');
myimg.height = myimg.height * 2;
myimg.width = myimg.width * 2;

AVD cant find SDK root, possibly because they are in different directories.Set your environment variables as shown in the screenshot below:

Search for [ ]{2,}. This will find two or more adjacent spaces anywhere within the line. It will also match leading and trailing spaces as well as lines that consist entirely of spaces. If you don't want that, check out Alexander's answer.

Actually, you can leave out the brackets, they are just for clarity (otherwise the space character that is being repeated isn't that well visible :)).

The problem with \s{2,} is that it will also match newlines on Windows files (where newlines are denoted by CRLF or \r\n which is matched by \s{2}.

If you also want to find multiple tabs and spaces, use [ \t]{2,}.

The #! line tells the kernel (specifically, the implementation of the execve system call) that this program is written in an interpreted language; the absolute pathname that follows identifies the interpreter. Programs compiled to machine code begin with a different byte sequence -- on most modern Unixes, 7f 45 4c 46 (^?ELF) that identifies them as such.

You can put an absolute path to any program you want after the #!, as long as that program is not itself a #! script. The kernel rewrites an invocation of

./script arg1 arg2 arg3 ...

where ./script starts with, say, #! /usr/bin/perl, as if the command line had actually been

/usr/bin/perl ./script arg1 arg2 arg3

Or, as you have seen, you can use #! /bin/sh to write a script intended to be interpreted by sh.

The #! line is only processed if you directly invoke the script (./script on the command line); the file must also be executable (chmod +x script). If you do sh ./script the #! line is not necessary (and will be ignored if present), and the file does not have to be executable. The point of the feature is to allow you to directly invoke interpreted-language programs without having to know what language they are written in. (Do grep '^#!' /usr/bin/* -- you will discover that a great many stock programs are in fact using this feature.)

Here are some rules for using this feature:

• The #! must be the very first two bytes in the file. In particular, the file must be in an ASCII-compatible encoding (e.g. UTF-8 will work, but UTF-16 won't) and must not start with a "byte order mark", or the kernel will not recognize it as a #! script.
• The path after #! must be an absolute path (starts with /). It cannot contain space, tab, or newline characters.
• It is good style, but not required, to put a space between the #! and the /. Do not put more than one space there.
• You cannot put shell variables on the #! line, they will not be expanded.
• You can put one command-line argument after the absolute path, separated from it by a single space. Like the absolute path, this argument cannot contain space, tab, or newline characters. Sometimes this is necessary to get things to work (#! /usr/bin/awk -f), sometimes it's just useful (#! /usr/bin/perl -Tw). Unfortunately, you cannot put two or more arguments after the absolute path.
• Some people will tell you to use #! /usr/bin/env interpreter instead of #! /absolute/path/to/interpreter. This is almost always a mistake. It makes your program's behavior depend on the $PATH variable of the user who invokes the script. And not all systems have env in the first place.
• Programs that need setuid or setgid privileges can't use #!; they have to be compiled to machine code. (If you don't know what setuid is, don't worry about this.)

Regarding csh, it relates to sh roughly as Nutrimat Advanced Tea Substitute does to tea. It has (or rather had; modern implementations of sh have caught up) a number of advantages over sh for interactive usage, but using it (or its descendant tcsh) for scripting is almost always a mistake. If you're new to shell scripting in general, I strongly recommend you ignore it and focus on sh. If you are using a csh relative as your login shell, switch to bash or zsh, so that the interactive command language will be the same as the scripting language you're learning.

You must do the following command:

sort -n -k1 filename

That should do it :)

To answer your question regarding updating openssl I followed these steps to successfully update the version found on my Mac to the newest openssl version 1.0.1e.

I followed the steps found here: http://foodpicky.com/?p=99

When you reach the steps for terminal commands make and make install be sure to use sudo make and sudo make install (I had to go through the step-by-step twice because I did it without sudo and it did not update).

Hope this helps

If you want to toggle a class to an element using native solution, you could try this suggestion. I have tasted it in different cases, with or without other classes onto the element, and I think it works pretty much:

(function(objSelector, objClass){
   document.querySelectorAll(objSelector).forEach(function(o){
      o.addEventListener('click', function(e){
        var $this = e.target,
            klass = $this.className,
            findClass = new RegExp('\\b\\s*' + objClass + '\\S*\\s?', 'g');

        if( !findClass.test( $this.className ) )
            if( klass ) 
                $this.className = klass + ' ' + objClass;
            else 
                $this.setAttribute('class', objClass);
        else 
        {
            klass = klass.replace( findClass, '' );
            if(klass) $this.className = klass;
            else $this.removeAttribute('class');
        }
    });
  });
})('.yourElemetnSelector', 'yourClass');

Try the following code :

$username='ABC';
$password='XYZ';
$URL='<URL>';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$URL);
curl_setopt($ch, CURLOPT_TIMEOUT, 30); //timeout after 30 seconds
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
$result=curl_exec ($ch);
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);   //get status code
curl_close ($ch);

If you trust the data source, you can use eval to convert your string into a dictionary:

eval(your_json_format_string)

Example:

>>> x = "{'a' : 1, 'b' : True, 'c' : 'C'}"
>>> y = eval(x)

>>> print x
{'a' : 1, 'b' : True, 'c' : 'C'}
>>> print y
{'a': 1, 'c': 'C', 'b': True}

>>> print type(x), type(y)
<type 'str'> <type 'dict'>

>>> print y['a'], type(y['a'])
1 <type 'int'>

>>> print y['a'], type(y['b'])
1 <type 'bool'>

>>> print y['a'], type(y['c'])
1 <type 'str'>

I like using a package.json file in the root of your app folder.

At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.

It could look like this:

LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here

FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();   

Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();

Simply choose whatever Integer value you want for the ID:

rowLayout.setId(12345);

If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.

UPDATE:

Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".

MainActivity.java:

public class MainActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);

        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        ll.setId(12345);

        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();

        fragContainer.addView(ll);
    }
}

TestFragment.java:

public class TestFragment extends Fragment {

    public static TestFragment newInstance(String text) {

        TestFragment f = new TestFragment();

        Bundle b = new Bundle();
        b.putString("text", text);
        f.setArguments(b);
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v =  inflater.inflate(R.layout.fragment, container, false);

        ((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));     
        return v;
    }
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/llFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="19dp"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

fragment.xml:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp" >

    <TextView
        android:id="@+id/tvFragText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="" />

</RelativeLayout>

And this is the result of the above code: (the two Fragments are aligned next to each other)

I installed console add-on of the firefox (https://addons.mozilla.org/en-US/android/addon/console/) on my firefox browser on android and it worked quite well. Helped me debug my angular2 app.

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

Since you're using requests, you should use the response's json method.

import requests

response = requests.get(...)
data = response.json()

It autodetects which decoder to use.

I think it is linked with your RAM (or probably virtual memory) space and for the absolute maximum constrained to your OS version (e.g. 32 bit or 64 bit)

1. About onCreate() and onUpgrade()

onCreate(..) is called whenever the app is freshly installed. onUpgrade is called whenever the app is upgraded and launched and the database version is not the same.

2. Incrementing the db version

You need a constructor like:

MyOpenHelper(Context context) {
   super(context, "dbname", null, 2); // 2 is the database version
}

IMPORTANT: Incrementing the app version alone is not enough for onUpgrade to be called!

3. Don't forget your new users!

Don't forget to add

database.execSQL(DATABASE_CREATE_color);

to your onCreate() method as well or newly installed apps will lack the table.

4. How to deal with multiple database changes over time

When you have successive app upgrades, several of which have database upgrades, you want to be sure to check oldVersion:

onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
   switch(oldVersion) {
   case 1:
       db.execSQL(DATABASE_CREATE_color);
       // we want both updates, so no break statement here...
   case 2:
       db.execSQL(DATABASE_CREATE_someothertable); 
   }
}

This way when a user upgrades from version 1 to version 3, they get both updates. When a user upgrades from version 2 to 3, they just get the revision 3 update... After all, you can't count on 100% of your user base to upgrade each time you release an update. Sometimes they skip an update or 12 :)

5. Keeping your revision numbers under control while developing

And finally... calling

adb uninstall <yourpackagename>

totally uninstalls the app. When you install again, you are guaranteed to hit onCreate which keeps you from having to keep incrementing the database version into the stratosphere as you develop...

Don't know how you want to format it, but you can do:

print("Created at %s:%s" % (t1.hour, t1.minute))

for example.

Description

The following will give you the size of the browsers viewport.

Sample

$(window).height();   // returns height of browser viewport
$(window).width();   // returns width of browser viewport

More Information

• jQuery.height()
• jQUery.width()

First, you should make sure that document.getElementsByName("username")[0] actually returns an object and not "undefined". You can simply check like

if (typeof document.getElementsByName("username")[0] != 'undefined')

Similarly for the other element password.

git checkout foo/bar.txt

did you tried that? (without a HEAD keyword)

I usually revert my changes this way.

If you are using dj-database-url check the schema in your DATABASES

https://github.com/kennethreitz/dj-database-url

MySQL is

'default': dj_database_url.config(default='mysql://USER:PASSWORD@localhost:PORT/NAME') 

It solves the same error even without the PORT

You set the password with:

mysql -u user -p 

If it's really required to access SessionFactory through @Autowire, I'd rather configure another EntityManagerFactory and then use it to configure the SessionFactory bean, like following:

@Configuration
public class SessionFactoryConfig {

@Autowired 
DataSource dataSource;

@Autowired
JpaVendorAdapter jpaVendorAdapter;

@Bean
@Primary
public EntityManagerFactory entityManagerFactory() {
    LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
    emf.setDataSource(dataSource);
    emf.setJpaVendorAdapter(jpaVendorAdapter);
    emf.setPackagesToScan("com.hibernateLearning");
    emf.setPersistenceUnitName("default");
    emf.afterPropertiesSet();
    return emf.getObject();
}

@Bean
public SessionFactory setSessionFactory(EntityManagerFactory entityManagerFactory) {
    return entityManagerFactory.unwrap(SessionFactory.class);
} }

You have 2 options :

1. Create a third method that wrap both methods. Advantage here is that you put less logic in your template.

2. Otherwise if you want to add 2 calls in ng-click you can add ';' after edit($index) like this

   ng-click="edit($index); open()"

I'm on lubuntu 19.10

I've used combination of previous answers, and didn't tweak the $PATH.

1. npm uninstall --global gulp gulp-cli This removes any package if they are already there.
2. sudo npm install --global gulp-cli Reinstall it as root user.

If you want to do copy and paste

npm uninstall --global gulp gulp-cli && sudo npm install --global gulp-cli 

should work

I guess --global is unnecessary here as it's installed using sudo, but I've used it just in case.

This code is working for me

Dim N As Long, r As Range
N = Cells(Rows.Count, "B").End(xlUp).Row
For i = 1 To N
    Set r = Cells(i, "B")
    r.Value = CDate(r.Value)
Next i

Try it changing the columns to suit your sheet

Simple, I suppose. The onclick attribute works nicely...

<select onchange="if(this.value == '') this.selectedIndex = 1; ">_x000D_
  <option value="">Select an Option</option>_x000D_
  <option value="one">Option 1</option>_x000D_
  <option value="two">Option 2</option>_x000D_
</select>

After a different option is selected, if the first option is selected, Option 1 will be selected. If you want an explanation on the javascript, just ask.

Here's yet another, but I feel more straightforward and intuitive (or at least natural if you're used to Promises), approach. Basically, you create an Observable using Observable.create() to wrap one and two as a single Observable. This is very similar to how Promise.all() may work.

var first = someObservable.take(1);
var second = Observable.create((observer) => {
  return first.subscribe(
    function onNext(value) {
      /* do something with value like: */
      // observer.next(value);
    },
    function onError(error) {
      observer.error(error);
    },
    function onComplete() {
      someOtherObservable.take(1).subscribe(
        function onNext(value) {
          observer.next(value);
        },
        function onError(error) {
          observer.error(error);
        },
        function onComplete() {
          observer.complete();
        }
      );
    }
  );
});

So, what's going on here? First, we create a new Observable. The function passed to Observable.create(), aptly named onSubscription, is passed the observer (built from the parameters you pass to subscribe()), which is similar to resolve and reject combined into a single object when creating a new Promise. This is how we make the magic work.

In onSubscription, we subscribe to the first Observable (in the example above, this was called one). How we handle next and error is up to you, but the default provided in my sample should be appropriate generally speaking. However, when we receive the complete event, which means one is now done, we can subscribe to the next Observable; thereby firing the second Observable after the first one is complete.

The example observer provided for the second Observable is fairly simple. Basically, second now acts like what you would expect two to act like in the OP. More specifically, second will emit the first and only the first value emitted by someOtherObservable (because of take(1)) and then complete, assuming there is no error.

Example

Here is a full, working example you can copy/paste if you want to see my example working in real life:

var someObservable = Observable.from([1, 2, 3, 4, 5]);
var someOtherObservable = Observable.from([6, 7, 8, 9]);

var first = someObservable.take(1);
var second = Observable.create((observer) => {
  return first.subscribe(
    function onNext(value) {
      /* do something with value like: */
      observer.next(value);
    },
    function onError(error) {
      observer.error(error);
    },
    function onComplete() {
      someOtherObservable.take(1).subscribe(
        function onNext(value) {
          observer.next(value);
        },
        function onError(error) {
          observer.error(error);
        },
        function onComplete() {
          observer.complete();
        }
      );
    }
  );
}).subscribe(
  function onNext(value) {
    console.log(value);
  },
  function onError(error) {
    console.error(error);
  },
  function onComplete() {
    console.log("Done!");
  }
);

If you watch the console, the above example will print:

1

6

Done!

You can also use the index for the sheet:

xls = pd.ExcelFile('path_to_file.xls')
sheet1 = xls.parse(0)

will give the first worksheet. for the second worksheet:

sheet2 = xls.parse(1)

The first path in the path variable needs to be the NPM path. Opening the Node.js command prompt I found that the ng command worked there. I dug into the shortcut and found that it references a command to ensure the first Path variable is NPM. To Fix:

1. Right Clicked on My Computer (windows)
2. Selected Advanced System Settings
3. Clicked "Environment Variables"
4. Under "Path" variable, made the FIRST value listed %AppData%\npm

Once I did that I was able to close powershell and reopen and all worked.

That's what ln is documented to do when the target already exists and is a directory. If you want /etc/nginx to be a symlink rather than contain a symlink, you had better not create it as a directory first!

You can do this using list comprehensions and min() (Python 3.0 code):

>>> nums = [1,2,3,4,5]
>>> [(x,y) for x in nums for y in nums]
[(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (5, 1), (5, 2), (5, 3), (5, 4), (5, 5)]
>>> min(_, key=lambda pair: pair[0]/pair[1])
(1, 5)

Note that to run this on Python 2.5 you'll need to either make one of the arguments a float, or do from __future__ import division so that 1/5 correctly equals 0.2 instead of 0.

As Homebrew is my favorite for macOS although it is possible to have apt-get on macOS using Fink.

This is my work around:

1) Add a wrapper div to the recaptcha div.

<div id="recaptcha-wrapper"><div class="g-recaptcha" data-sitekey="..."></div></div>

2) Add javascript/jquery code.

$(function(){
    // global variables
    captchaResized = false;
    captchaWidth = 304;
    captchaHeight = 78;
    captchaWrapper = $('#recaptcha-wrapper');
    captchaElements = $('#rc-imageselect, .g-recaptcha');

    resizeCaptcha();
    $(window).on('resize', function() {
        resizeCaptcha();
    });
});

function resizeCaptcha() {
    if (captchaWrapper.width() >= captchaWidth) {
        if (captchaResized) {
            captchaElements.css('transform', '').css('-webkit-transform', '').css('-ms-transform', '').css('-o-transform', '').css('transform-origin', '').css('-webkit-transform-origin', '').css('-ms-transform-origin', '').css('-o-transform-origin', '');
            captchaWrapper.height(captchaHeight);
            captchaResized = false;
        }
    } else {
        var scale = (1 - (captchaWidth - captchaWrapper.width()) * (0.05/15));
        captchaElements.css('transform', 'scale('+scale+')').css('-webkit-transform', 'scale('+scale+')').css('-ms-transform', 'scale('+scale+')').css('-o-transform', 'scale('+scale+')').css('transform-origin', '0 0').css('-webkit-transform-origin', '0 0').css('-ms-transform-origin', '0 0').css('-o-transform-origin', '0 0');
        captchaWrapper.height(captchaHeight * scale);
        if (captchaResized == false) captchaResized = true;
    }
}

3) Optional: add some styling if needed.

#recaptcha-wrapper { text-align:center; margin-bottom:15px; }

.g-recaptcha { display:inline-block; }

With Android's Newer Version >= API 16 use finishAffinity()

approach is suitable for >= API 16.

Intent mIntent = new Intent(mContext,MainActivity.class);
finishAffinity();
startActivity(mIntent);

• Its is same as starting new Activity, and clear all stack.
• OR Restart to MainActivity/FirstActivity.

Use setText(str) method of JLabel to dynamically change text displayed. In actionPerform of button write this:

jLabel.setText("new Value");

A simple demo code will be:

    JFrame frame = new JFrame("Demo");
    frame.setLayout(new BorderLayout());
    frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
    frame.setSize(250,100);

    final JLabel label = new JLabel("flag");
    JButton button = new JButton("Change flag");
    button.addActionListener(new ActionListener() {
        @Override
        public void actionPerformed(ActionEvent arg0) {
            label.setText("new value");
        }
    });

    frame.add(label, BorderLayout.NORTH);
    frame.add(button, BorderLayout.CENTER);
    frame.setVisible(true);

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

There isn't currently a built-in PowerShell method for doing the SFTP part. You'll have to use something like psftp.exe or a PowerShell module like Posh-SSH.

Here is an example using Posh-SSH:

# Set the credentials
$Password = ConvertTo-SecureString 'Password1' -AsPlainText -Force
$Credential = New-Object System.Management.Automation.PSCredential ('root', $Password)

# Set local file path, SFTP path, and the backup location path which I assume is an SMB path
$FilePath = "C:\FileDump\test.txt"
$SftpPath = '/Outbox'
$SmbPath = '\\filer01\Backup'

# Set the IP of the SFTP server
$SftpIp = '10.209.26.105'

# Load the Posh-SSH module
Import-Module C:\Temp\Posh-SSH

# Establish the SFTP connection
$ThisSession = New-SFTPSession -ComputerName $SftpIp -Credential $Credential

# Upload the file to the SFTP path
Set-SFTPFile -SessionId ($ThisSession).SessionId -LocalFile $FilePath -RemotePath $SftpPath

#Disconnect all SFTP Sessions
Get-SFTPSession | % { Remove-SFTPSession -SessionId ($_.SessionId) }

# Copy the file to the SMB location
Copy-Item -Path $FilePath -Destination $SmbPath

Some additional notes:

• You'll have to download the Posh-SSH module which you can install to your user module directory (e.g. C:\Users\jon_dechiro\Documents\WindowsPowerShell\Modules) and just load using the name or put it anywhere and load it like I have in the code above.
• If having the credentials in the script is not acceptable you'll have to use a credential file. If you need help with that I can update with some details or point you to some links.
• Change the paths, IPs, etc. as needed.

That should give you a decent starting point.

Microsoft's GUID's textual representation can be in the form of a UUID being surrounded by two curly braces {}.

It is commonly agreed that primary keys should be immutable (or as stable as possible since immutability can not be enforced in the DB). While there is nothing that will prevent you from updating a primary key (except integrity constraint), it may not be a good idea:

From a performance point of view:

• You will need to update all foreign keys that reference the updated key. A single update can lead to the update of potentially lots of tables/rows.
• If the foreign keys are unindexed (!!) you will have to maintain a lock on the children table to ensure integrity. Oracle will only hold the lock for a short time but still, this is scary.
• If your foreign keys are indexed (as they should be), the update will lead to the update of the index (delete+insert in the index structure), this is generally more expensive than the actual update of the base table.
• In ORGANIZATION INDEX tables (in other RDBMS, see clustered primary key), the rows are physically sorted by the primary key. A logical update will result in a physical delete+insert (more expensive)

Other considerations:

• If this key is referenced in any external system (application cache, another DB, export...), the reference will be broken upon update.
• additionaly, some RDBMS don't support CASCADE UPDATE, in particular Oracle.

In conclusion, during design, it is generally safer to use a surrogate key in lieu of a natural primary key that is supposed not to change -- but may eventually need to be updated because of changed requirements or even data entry error.

If you absolutely have to update a primary key with children table, see this post by Tom Kyte for a solution.

Use tail command:

ls -t | tail -n 5

I assumed the first DIV is #content :

<div id="content">
   <img src="@Url.Content("~/images/image1.bmp")" alt="" />
   <img src="@Url.Content("~/images/image2.bmp")" alt="" />
   <img src="@Url.Content("~/images/image3.bmp")" alt="" />
</div>

And CSS :

#content{
         width: 700px;
         display: block;
         height: auto;
     }
     #content > img{
        float: left; width: 200px;
        height: 200px;
        margin: 5px 8px;
     }

There are two issues here.

Firstly, you can't use the [] syntax like you may be able to in other languages. Square brackets only apply to arrays in Java, and so can only be used with integer indexes.

data.put is correct but that is a statement and so must exist in a method block. Only field declarations can exist at the class level. Here is an example where everything is within the local scope of a method:

public class Data {
     public static void main(String[] args) {
         Map<String, String> data = new HashMap<String, String>();
         data.put("John", "Taxi Driver");
         data.put("Mark", "Professional Killer");
     }
 }

If you want to initialize a map as a static field of a class then you can use Map.of, since Java 9:

public class Data {
    private static final Map<String, String> DATA = Map.of("John", "Taxi Driver");
}

Before Java 9, you can use a static initializer block to accomplish the same thing:

public class Data {
    private static final Map<String, String> DATA = new HashMap<>();

    static {
        DATA.put("John", "Taxi Driver");
    }
}

Make a virtual enviroment using python3

virtualenv env_name --python="python3"

and run the following command

pip3 install opencv-python

I also ran into the same issue the other day. Google search got me here and several other places, but none gave the solution to this issue. I ended up saving the uploaded file (MultiPartFile) as a tmp file, then use FileSystemResource to upload it via RestTemplate. Here's the code I use,

String tempFileName = "/tmp/" + multiFile.getOriginalFileName();
FileOutputStream fo = new FileOutputStream(tempFileName);

fo.write(asset.getBytes());    
fo.close();   

parts.add("file", new FileSystemResource(tempFileName));    
String response = restTemplate.postForObject(uploadUrl, parts, String.class, authToken, path);   


//clean-up    
File f = new File(tempFileName);    
f.delete();

I am still looking for a more elegant solution to this problem.

As of Laravel >= 5.3, best way is to use value:

$groupName = \App\User::where('username',$username)->value('groupName');

or

use App\User;//at top of controller
$groupName = User::where('username',$username)->value('groupName');//inside controller function

Of course you have to create a model User for users table which is most efficient way to interact with database tables in Laravel.

I changed the hide/show event trigger from Catalint based on Glenns idea. My problem was that I have a modular application. I change between modules showing and hiding divs parents. Then when I hide a module and show another one, with his method I have a visible delay when I change between modules. I only need sometimes to liten this event, and in some special childs. So I decided to notify only the childs with the class "displayObserver"

$.each(["show", "hide", "toggleClass", "addClass", "removeClass"], function () {
    var _oldFn = $.fn[this];
    $.fn[this] = function () {
        var hidden = this.find(".displayObserver:hidden").add(this.filter(":hidden"));
        var visible = this.find(".displayObserver:visible").add(this.filter(":visible"));
        var result = _oldFn.apply(this, arguments);
        hidden.filter(":visible").each(function () {
            $(this).triggerHandler("show");
        }); 
        visible.filter(":hidden").each(function () {
            $(this).triggerHandler("hide");
        });
        return result;
    }

Then when a child wants to listen for "show" or "hide" event I have to add him the class "displayObserver", and when It does not want to continue listen it, I remove him the class

bindDisplayEvent: function () {
   $("#child1").addClass("displayObserver");
   $("#child1").off("show", this.onParentShow);
   $("#child1").on("show", this.onParentShow);
},

bindDisplayEvent: function () {

To get a .class file you have to compile the .java file.

The command for this is javac. The manual for this is found here (Windows)

In short:

javac File.java

I lived this problem in two days and suddenly I realized it that I am using this click method(for asp button) in a submit button(in html submit button) javascript method...

I mean ->

I have an html submit button and an asp button like these:

<input type="submit" value="Siparisi Gönder" onclick="SendEmail()" />_x000D_
<asp:Button ID="sendEmailButton" runat="server" Text="Gönder" OnClick="SendToEmail" Visible="True"></asp:Button>

SendToEmail() is a server side method in Default.aspx SendEmail() is a javascript method like this:

<script type="text/javascript" lang="javascript">_x000D_
   function SendEmail() {_x000D_
            document.getElementById('<%= sendEmailButton.UniqueID %>').click();_x000D_
            alert("Your message is sending...");_x000D_
        }_x000D_
</script>

And this "document.getElementById('<%= sendEmailButton.UniqueID %>').click();" method did not work in just Crome. It was working in IE and Firefox.

Then I tried and tried a lot of ways for executing "SendToEmail()" method in Crome.

Then suddenly I changed html submit button --> just html button like this and now it is working:

<input type="button" value="Siparisi Gönder" onclick="SendEmail()" />

Have a nice days...

There are multiple ways to calculate the distance based on the coordinates i.e latitude and longitude

Install and import

from geopy import distance
from math import sin, cos, sqrt, atan2, radians
from sklearn.neighbors import DistanceMetric
import osrm
import numpy as np

Define coordinates

lat1, lon1, lat2, lon2, R = 20.9467,72.9520, 21.1702, 72.8311, 6373.0
coordinates_from = [lat1, lon1]
coordinates_to = [lat2, lon2]

Using haversine

dlon = radians(lon2) - radians(lon1)
dlat = radians(lat2) - radians(lat1)
    
a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1 - a))
    
distance_haversine_formula = R * c
print('distance using haversine formula: ', distance_haversine_formula)

Using haversine with sklearn

dist = DistanceMetric.get_metric('haversine')
    
X = [[radians(lat1), radians(lon1)], [radians(lat2), radians(lon2)]]
distance_sklearn = R * dist.pairwise(X)
print('distance using sklearn: ', np.array(distance_sklearn).item(1))

Using OSRM

osrm_client = osrm.Client(host='http://router.project-osrm.org')
coordinates_osrm = [[lon1, lat1], [lon2, lat2]] # note that order is lon, lat
    
osrm_response = osrm_client.route(coordinates=coordinates_osrm, overview=osrm.overview.full)
dist_osrm = osrm_response.get('routes')[0].get('distance')/1000 # in km
print('distance using OSRM: ', dist_osrm)

Using geopy

distance_geopy = distance.distance(coordinates_from, coordinates_to).km
print('distance using geopy: ', distance_geopy)
    
distance_geopy_great_circle = distance.great_circle(coordinates_from, coordinates_to).km 
print('distance using geopy great circle: ', distance_geopy_great_circle)

Output

distance using haversine formula:  26.07547017310917
distance using sklearn:  27.847882224769783
distance using OSRM:  33.091699999999996
distance using geopy:  27.7528030550408
distance using geopy great circle:  27.839182219511834

Usually what you choose will depend on which methods you need access to. In general - IEnumerable<> (MSDN: http://msdn.microsoft.com/en-us/library/system.collections.ienumerable.aspx) for a list of objects that only needs to be iterated through, ICollection<> (MSDN: http://msdn.microsoft.com/en-us/library/92t2ye13.aspx) for a list of objects that needs to be iterated through and modified, List<> for a list of objects that needs to be iterated through, modified, sorted, etc (See here for a full list: http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx).

From a more specific standpoint, lazy loading comes in to play with choosing the type. By default, navigation properties in Entity Framework come with change tracking and are proxies. In order for the dynamic proxy to be created as a navigation property, the virtual type must implement ICollection.

A navigation property that represents the "many" end of a relationship must return a type that implements ICollection, where T is the type of the object at the other end of the relationship. -Requirements for Creating POCO Proxies^MSDN

Relying on compiler optimizations is fragile. The benchmarks linked in the accepted answer and numbers given by Antoine-tran are not to be trusted. Andrew Hare makes the mistake of including a call to repr in his methods. That slows all the methods equally but obscures the real penalty in constructing the string.

Use join. It's very fast and more robust.

I am just providing another case where you can get this error message. The solution will be the same as Adam has mentioned above. This is from a real code and I renamed the class name.

class FooReader {
  public:
     /** Constructor */
     FooReader() : d(new FooReaderPrivate(this)) { }  // will not compile here
     .......
  private:
     FooReaderPrivate* d;
};

====== In a separate file =====
class FooReaderPrivate {
  public:
     FooReaderPrivate(FooReader*) : parent(p) { }
  private:
     FooReader* parent;
};

The above will no pass the compiler and get error: invalid use of incomplete type FooReaderPrivate. You basically have to put the inline portion into the *.cpp implementation file. This is OK. What I am trying to say here is that you may have a design issue. Cross reference of two classes may be necessary some cases, but I would say it is better to avoid them at the start of the design. I would be wrong, but please comment then I will update my posting.

simple way to prevent the whole app from getting effected by system font size is to updateConfiguration using a base activity.

//in base activity add this code.
public  void adjustFontScale( Configuration configuration) {

    configuration.fontScale = (float) 1.0;
    DisplayMetrics metrics = getResources().getDisplayMetrics();
    WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
    wm.getDefaultDisplay().getMetrics(metrics);
    metrics.scaledDensity = configuration.fontScale * metrics.density;
    getBaseContext().getResources().updateConfiguration(configuration, metrics);

}

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    adjustFontScale( getResources().getConfiguration());
}

You are exceeding the length of int datatype. You can use UNSIGNED attribute to support that value.

SIGNED INT can support till 2147483647 and with UNSIGNED INT allows double than this. After this you still want to save data than use CHAR or VARCHAR with length 10

switching workspace worked for me. Go to File > Switch Workspace and choose different folder (workspace) That's it and BINGO! Debugging started working for me as beautiful as before.

wanna add to main answer above
I tried to follow it but my recyclerView began to stretch every item to a screen
I had to add next line after inflating for reach to goal

I already added these params by xml but it didnot work correctly
and with this line all is ok

Assuming the changes you want are at the head of the branch you want the changes from, use git checkout

for a single file :

git checkout branch_that_has_the_changes_you_want path/to/file.rb

for multiple files just daisy chain :

git checkout branch_that_has_the_changes_you_want path/to/file.rb path/to/other_file.rb

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

Eclipse uses it's own internal compiler that can compile to several Java versions.

From Eclipse Help > Java development user guide > Concepts > Java Builder

The Java builder builds Java programs using its own compiler (the Eclipse Compiler for Java) that implements the Java Language Specification.

For Eclipse Mars.1 Release (4.5.1), this can target 1.3 to 1.8 inclusive.

When you configure a project:

[project-name] > Properties > Java Compiler > Compiler compliance level

This configures the Eclipse Java compiler to compile code to the specified Java version, typically 1.8 today.

Host environment variables, eg JAVA_HOME etc, are not used.

The Oracle/Sun JDK compiler is not used.

I know its already answered, but theres a better solution here use this code :

for ( Field f : context.getFields() ) {
     if ( f.getType() == String.class ) || ( f.getType() == String.class ) ) {
           //DO String To JSON
     }
     /// And so on...
}

This way you can access variables from class without manually typing them..

Faster and better .. Hope this helps.

Cheers. :D

virtualenv is a tool to create isolated Python environments.

you will need to add the following to fix command python setup.py egg_info failed with error code 1, so inside your requirements.txt add this:

virtualenv==12.0.7

I had same problem and this accepted solution didn't helped me, if someone has same problem you can use my code snippet:

// example of filtering and sharing multiple images with texts
// remove facebook from sharing intents
private void shareFilter(){

    String share = getShareTexts();
    ArrayList<Uri> uris = getImageUris();

    List<Intent> targets = new ArrayList<>();
    Intent template = new Intent(Intent.ACTION_SEND_MULTIPLE);
    template.setType("image/*");
    List<ResolveInfo> candidates = getActivity().getPackageManager().
            queryIntentActivities(template, 0);

    // remove facebook which has a broken share intent
    for (ResolveInfo candidate : candidates) {
        String packageName = candidate.activityInfo.packageName;
        if (!packageName.equals("com.facebook.katana")) {
            Intent target = new Intent(Intent.ACTION_SEND_MULTIPLE);
            target.setType("image/*");
            target.putParcelableArrayListExtra(Intent.EXTRA_STREAM,uris);
            target.putExtra(Intent.EXTRA_TEXT, share);
            target.setPackage(packageName);
            targets.add(target);
        }
    }
    Intent chooser = Intent.createChooser(targets.remove(0), "Share Via");
    chooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, targets.toArray(new Parcelable[targets.size()]));
    startActivity(chooser);

}

You can use the data attribute:

<div class="datepicker" data-date-start-date="+1d"></div>

Introduction

To browse and select a file for upload you need a HTML <input type="file"> field in the form. As stated in the HTML specification you have to use the POST method and the enctype attribute of the form has to be set to "multipart/form-data".

<form action="upload" method="post" enctype="multipart/form-data">
    <input type="text" name="description" />
    <input type="file" name="file" />
    <input type="submit" />
</form>

After submitting such a form, the binary multipart form data is available in the request body in a different format than when the enctype isn't set.

Before Servlet 3.0, the Servlet API didn't natively support multipart/form-data. It supports only the default form enctype of application/x-www-form-urlencoded. The request.getParameter() and consorts would all return null when using multipart form data. This is where the well known Apache Commons FileUpload came into the picture.

Don't manually parse it!

You can in theory parse the request body yourself based on ServletRequest#getInputStream(). However, this is a precise and tedious work which requires precise knowledge of RFC2388. You shouldn't try to do this on your own or copypaste some homegrown library-less code found elsewhere on the Internet. Many online sources have failed hard in this, such as roseindia.net. See also uploading of pdf file. You should rather use a real library which is used (and implicitly tested!) by millions of users for years. Such a library has proven its robustness.

When you're already on Servlet 3.0 or newer, use native API

If you're using at least Servlet 3.0 (Tomcat 7, Jetty 9, JBoss AS 6, GlassFish 3, etc), then you can just use standard API provided HttpServletRequest#getPart() to collect the individual multipart form data items (most Servlet 3.0 implementations actually use Apache Commons FileUpload under the covers for this!). Also, normal form fields are available by getParameter() the usual way.

First annotate your servlet with @MultipartConfig in order to let it recognize and support multipart/form-data requests and thus get getPart() to work:

@WebServlet("/upload")
@MultipartConfig
public class UploadServlet extends HttpServlet {
    // ...
}

Then, implement its doPost() as follows:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String description = request.getParameter("description"); // Retrieves <input type="text" name="description">
    Part filePart = request.getPart("file"); // Retrieves <input type="file" name="file">
    String fileName = Paths.get(filePart.getSubmittedFileName()).getFileName().toString(); // MSIE fix.
    InputStream fileContent = filePart.getInputStream();
    // ... (do your job here)
}

Note the Path#getFileName(). This is a MSIE fix as to obtaining the file name. This browser incorrectly sends the full file path along the name instead of only the file name.

In case you have a <input type="file" name="file" multiple="true" /> for multi-file upload, collect them as below (unfortunately there is no such method as request.getParts("file")):

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // ...
    List<Part> fileParts = request.getParts().stream().filter(part -> "file".equals(part.getName()) && part.getSize() > 0).collect(Collectors.toList()); // Retrieves <input type="file" name="file" multiple="true">

    for (Part filePart : fileParts) {
        String fileName = Paths.get(filePart.getSubmittedFileName()).getFileName().toString(); // MSIE fix.
        InputStream fileContent = filePart.getInputStream();
        // ... (do your job here)
    }
}

When you're not on Servlet 3.1 yet, manually get submitted file name

Note that Part#getSubmittedFileName() was introduced in Servlet 3.1 (Tomcat 8, Jetty 9, WildFly 8, GlassFish 4, etc). If you're not on Servlet 3.1 yet, then you need an additional utility method to obtain the submitted file name.

private static String getSubmittedFileName(Part part) {
    for (String cd : part.getHeader("content-disposition").split(";")) {
        if (cd.trim().startsWith("filename")) {
            String fileName = cd.substring(cd.indexOf('=') + 1).trim().replace("\"", "");
            return fileName.substring(fileName.lastIndexOf('/') + 1).substring(fileName.lastIndexOf('\\') + 1); // MSIE fix.
        }
    }
    return null;
}

String fileName = getSubmittedFileName(filePart);

Note the MSIE fix as to obtaining the file name. This browser incorrectly sends the full file path along the name instead of only the file name.

When you're not on Servlet 3.0 yet, use Apache Commons FileUpload

If you're not on Servlet 3.0 yet (isn't it about time to upgrade?), the common practice is to make use of Apache Commons FileUpload to parse the multpart form data requests. It has an excellent User Guide and FAQ (carefully go through both). There's also the O'Reilly ("cos") MultipartRequest, but it has some (minor) bugs and isn't actively maintained anymore for years. I wouldn't recommend using it. Apache Commons FileUpload is still actively maintained and currently very mature.

In order to use Apache Commons FileUpload, you need to have at least the following files in your webapp's /WEB-INF/lib:

• commons-fileupload.jar
• commons-io.jar

Your initial attempt failed most likely because you forgot the commons IO.

Here's a kickoff example how the doPost() of your UploadServlet may look like when using Apache Commons FileUpload:

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    try {
        List<FileItem> items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
        for (FileItem item : items) {
            if (item.isFormField()) {
                // Process regular form field (input type="text|radio|checkbox|etc", select, etc).
                String fieldName = item.getFieldName();
                String fieldValue = item.getString();
                // ... (do your job here)
            } else {
                // Process form file field (input type="file").
                String fieldName = item.getFieldName();
                String fileName = FilenameUtils.getName(item.getName());
                InputStream fileContent = item.getInputStream();
                // ... (do your job here)
            }
        }
    } catch (FileUploadException e) {
        throw new ServletException("Cannot parse multipart request.", e);
    }

    // ...
}

It's very important that you don't call getParameter(), getParameterMap(), getParameterValues(), getInputStream(), getReader(), etc on the same request beforehand. Otherwise the servlet container will read and parse the request body and thus Apache Commons FileUpload will get an empty request body. See also a.o. ServletFileUpload#parseRequest(request) returns an empty list.

Note the FilenameUtils#getName(). This is a MSIE fix as to obtaining the file name. This browser incorrectly sends the full file path along the name instead of only the file name.

Alternatively you can also wrap this all in a Filter which parses it all automagically and put the stuff back in the parametermap of the request so that you can continue using request.getParameter() the usual way and retrieve the uploaded file by request.getAttribute(). You can find an example in this blog article.

Workaround for GlassFish3 bug of getParameter() still returning null

Note that Glassfish versions older than 3.1.2 had a bug wherein the getParameter() still returns null. If you are targeting such a container and can't upgrade it, then you need to extract the value from getPart() with help of this utility method:

private static String getValue(Part part) throws IOException {
    BufferedReader reader = new BufferedReader(new InputStreamReader(part.getInputStream(), "UTF-8"));
    StringBuilder value = new StringBuilder();
    char[] buffer = new char[1024];
    for (int length = 0; (length = reader.read(buffer)) > 0;) {
        value.append(buffer, 0, length);
    }
    return value.toString();
}

String description = getValue(request.getPart("description")); // Retrieves <input type="text" name="description">

Ajaxifying the form

Head to the following answers how to upload using Ajax (and jQuery). Do note that the servlet code to collect the form data does not need to be changed for this! Only the way how you respond may be changed, but this is rather trivial (i.e. instead of forwarding to JSP, just print some JSON or XML or even plain text depending on whatever the script responsible for the Ajax call is expecting).

With dplyr and stringr you can use mutate_all:

> df %>% mutate_all(funs(length = str_length(.)))

4 abcdefg        f           7           1

Barcode Detection is now available in Google Play services. Code lab of the setup process, here are the api docs, and a sample project.

Non-python data is best bundled inside your Python modules using the package_data support in setuptools. One thing I strongly recommend is using namespace packages to create shared namespaces which multiple projects can use -- much like the Java convention of putting packages in com.yourcompany.yourproject (and being able to have a shared com.yourcompany.utils namespace).

Re branching and merging, if you use a good enough source control system it will handle merges even through renames; Bazaar is particularly good at this.

Contrary to some other answers here, I'm +1 on having a src directory top-level (with doc and test directories alongside). Specific conventions for documentation directory trees will vary depending on what you're using; Sphinx, for instance, has its own conventions which its quickstart tool supports.

Please, please leverage setuptools and pkg_resources; this makes it much easier for other projects to rely on specific versions of your code (and for multiple versions to be simultaneously installed with different non-code files, if you're using package_data).

angular.module('myApp').controller('myCtrl', function($scope, $rootScope) {
   var a = //something in the scope
   //put it in the root scope
    $rootScope.test = "TEST";
 });

angular.module('myApp').controller('myCtrl2', function($scope, $rootScope) {
   var b = //get var a from root scope somehow
   //use var b

   $scope.value = $rootScope.test;
   alert($scope.value);

 //    var b = $rootScope.test;
 //  alert(b);
 });

DEMO

A lot of the answers here so far are Chrome only or incur an HTTP overhead penalty. The solution that we are using is a little different:

1. Add a new object to the manifest content_scripts list like so:

{
  "matches": ["https://www.yoursite.com/*"],
  "js": [
    "install_notifier.js"
  ],
  "run_at": "document_idle"
}

This will allow the code in install_notifier.js to run on that site (if you didn't already have permissions there).

2. Send a message to every site in the manifest key above.

Add something like this to install_notifier.js (note that this is using a closure to keep the variables from being global, but that's not strictly necessary):

// Dispatch a message to every URL that's in the manifest to say that the extension is
// installed.  This allows webpages to take action based on the presence of the
// extension and its version. This is only allowed for a small whitelist of
// domains defined in the manifest.
(function () {
  let currentVersion = chrome.runtime.getManifest().version;
  window.postMessage({
    sender: "my-extension",
    message_name: "version",
    message: currentVersion
  }, "*");
})();

Your message could say anything, but it's useful to send the version so you know what you're dealing with. Then...

3. On your website, listen for that message.

Add this to your website somewhere:

window.addEventListener("message", function (event) {
  if (event.source == window &&
    event.data.sender &&
    event.data.sender === "my-extension" &&
    event.data.message_name &&
    event.data.message_name === "version") {
    console.log("Got the message");
  }
});

This works in Firefox and Chrome, and doesn't incur HTTP overhead or manipulate the page.

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

How about using Guid.NewGuid() to create a GUID and use that as the filename (or part of the filename together with your time stamp if you like).

I started off using the community wiki answer, but realised that it wasn't detecting alt-tab events in Chrome. This is because it uses the first available event source, and in this case it's the page visibility API, which in Chrome seems to not track alt-tabbing.

I decided to modify the script a bit to keep track of all possible events for page focus changes. Here's a function you can drop in:

function onVisibilityChange(callback) {
    var visible = true;

    if (!callback) {
        throw new Error('no callback given');
    }

    function focused() {
        if (!visible) {
            callback(visible = true);
        }
    }

    function unfocused() {
        if (visible) {
            callback(visible = false);
        }
    }

    // Standards:
    if ('hidden' in document) {
        document.addEventListener('visibilitychange',
            function() {(document.hidden ? unfocused : focused)()});
    }
    if ('mozHidden' in document) {
        document.addEventListener('mozvisibilitychange',
            function() {(document.mozHidden ? unfocused : focused)()});
    }
    if ('webkitHidden' in document) {
        document.addEventListener('webkitvisibilitychange',
            function() {(document.webkitHidden ? unfocused : focused)()});
    }
    if ('msHidden' in document) {
        document.addEventListener('msvisibilitychange',
            function() {(document.msHidden ? unfocused : focused)()});
    }
    // IE 9 and lower:
    if ('onfocusin' in document) {
        document.onfocusin = focused;
        document.onfocusout = unfocused;
    }
    // All others:
    window.onpageshow = window.onfocus = focused;
    window.onpagehide = window.onblur = unfocused;
};

Use it like this:

onVisibilityChange(function(visible) {
    console.log('the page is now', visible ? 'focused' : 'unfocused');
});

This version listens for all the different visibility events and fires a callback if any of them causes a change. The focused and unfocused handlers make sure that the callback isn't called multiple times if multiple APIs catch the same visibility change.

Your arguments are in the wrong order. The connection comes first according to the docs

<?php
require("constants.php");

// 1. Create a database connection
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);

if (!$connection) {
    error_log("Failed to connect to MySQL: " . mysqli_error($connection));
    die('Internal server error');
}

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    error_log("Database selection failed: " . mysqli_error($connection));
    die('Internal server error');
}

?>

SQL Server requires a transaction log in order to function.

That said there are two modes of operation for the transaction log:

• Simple
• Full

In Full mode the transaction log keeps growing until you back up the database. In Simple mode: space in the transaction log is 'recycled' every Checkpoint.

Very few people have a need to run their databases in the Full recovery model. The only point in using the Full model is if you want to backup the database multiple times per day, and backing up the whole database takes too long - so you just backup the transaction log.

The transaction log keeps growing all day, and you keep backing just it up. That night you do your full backup, and SQL Server then truncates the transaction log, begins to reuse the space allocated in the transaction log file.

If you only ever do full database backups, you don't want the Full recovery mode.

I guess you want to do this:

$total_rating_count = count($total_rating_count);
if ($total_rating_count > 0) // because you can't divide through zero
   $avg = round($total_rating_points / $total_rating_count, 1);

I suspect it's just following the Linux / Unix standard for returning 0 on success.

Does it really say "1" is false and "0" is true?

Disable time in boostrap datetime picker...

   $(document).ready(function () {
        $('.timepicker').datetimepicker({
            format: "dd-mm-yy",
        });
    });

Disable date in boostrap datetime picker...

   $(document).ready(function () {
        $('.timepicker').datetimepicker({
            format: "HH:mm A",
        });
    });

I just stumbled upon this question and here is an update for Swift 3 and iOS 10:

let testUIBarButtonItem = UIBarButtonItem(image: UIImage(named: "test.png"), style: .plain, target: self, action: nil)
self.navigationItem.rightBarButtonItem  = testUIBarButtonItem

It is definitely much faster than creating the UIButton with all the properties and then subsequently adding the customView to the UIBarButtonItem.

And if you want to change the color of the image from the default blue to e.g. white, you can always change the tint color:

test.tintColor = UIColor.white()

PS You should obviously change the selector etc. for your app :)

You almost had it. If you want to pass the output of a command as parameters to another one, you'll need to use xargs. Adding -print0 makes sure the script can handle paths with whitespace:

find . -type d -name .svn -print0|xargs -0 rm -rf

Events can be retrieved using:

jQuery(elem).data('events');

or jQuery 1.8+:

jQuery._data(elem, 'events');

Note: Events bounded using $('selector').live('event', handler) can be retrieved using:

jQuery(document).data('events')

Using this solution, you will also be able to put the cursor at the end of newly text.

final TextEditingController _controller = TextEditingController();

@override
Widget build(BuildContext context) {
  return Scaffold(
    body: Center(child: TextField(controller: _controller)),
    floatingActionButton: FloatingActionButton(
      onPressed: () {
        _controller.text = "Hello";

        // this changes cursor position
        _controller.selection = TextSelection.fromPosition(TextPosition(offset: _controller.text.length));
        setState(() {});
      },
    ),
  );
}

Setting fork to true resolved the issue for me.

I think there is something wrong with method_defined? in Rails. It may be inconsistent or something, so if you use Rails, it's better to use something from attribute_method?(attribute).

"testing for method_defined? on ActiveRecord classes doesn't work until an instantiation" is a question about the inconsistency.

x = 10;
if(x > 100 ) console.log('over 100')
else if (x > 90 ) console.log('over 90')
else if (x > 50 ) console.log('over 50')
else if (x > 9 ) console.log('over 9')
else console.log('lower 9') 

No, there are no dictionaries in php. The closest thing you have is an array. However, an array is different than a dictionary in that arrays have both an index and a key. Dictionaries only have keys and no index. What do I mean by that?

$array = array(
    "foo" => "bar",
    "bar" => "foo"
);

// as of PHP 5.4
$array = [
    "foo" => "bar",
    "bar" => "foo",
];

The following line is allowed with the above array but would give an error if it was a dictionary.

print $array[0]

Python has both arrays and dictionaries.

I tried almost all of these techniques (except FXLabel) and couldn't get any of them to work with iOS 7. I did eventually find THLabel which is working perfectly for me. I used THLabel in Interface Builder and setup User Defined Runtime Attributes so that it's easy for a non programmer to control the look and feel.

Aditionally to the answer from @srk, you should uninstall package setuptools:

python -m pip uninstall pip setuptools

If you want to uninstall all other packages first, this answer has some hints: https://stackoverflow.com/a/11250821/265954

Note: before you use the commands from that answer, please carefully read the comments about side effects and how to avoid uninstalling pip and setuptools too early. E.g. pip freeze | grep -v "^-e" | grep -v "^(setuptools|pip)" | xargs pip uninstall -y

For setting the Socket timeout, you need to follow these steps:

import socket
socks = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
socks.settimeout(10.0) # settimeout is the attr of socks.

After lots of search finally this worked for me . I hope it helps.

Just like Nasser, I know this was a while ago but I wanted to post my solution for anyone who has this problem in the future.

I had my report setup so that it would use a data connection in a Data Connection library hosted on SharePoint. My issue was that I did not have the data connection 'approved' so that it was usable by other users.

Another thing to look for would to make sure that the permissions on that Data Connection library also allows read to the select users.

Hope this helps someone sooner or later!

It would take me a lot of convincing to switch from perforce. In the two companies I used it it was more than adequate. Those were both companies with disparate offices, but the offices were set up with plenty of infrastructure so there was no need to have the disjoint/disconnected features.

How many developers are you talking about changing over?

The real question is - what is it about perforce that is not meeting your organization's needs that git can provide? And similarly, what weaknesses does git have compared to perforce? If you can't answer that yourself then asking here won't help. You need to find a business case for your company. (e.g. Perhaps it is with lower overall cost of ownership (that includes loss of productivity for the interim learning stage, higher admin costs (at least initially), etc.)

I think you are in for a tough sell - perforce is a pretty good one to try to replace. It is a no brainer if you are trying to boot out pvcs or ssafe.

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

More based on the feeling, but this is the error you would get if you missed to declare a bean in the context configuration, so try adding

<bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
    <property name="maxUploadSize" value="10000000"/>
</bean>

You're on the right track with using document.getElementById() as you have done for your first two text boxes. Use something like document.getElementById("textbox3") to retrieve the element. Then you can just set its value property: document.getElementById("textbox3").value = answer;

For the "Your answer is: --", I'd recommend wrapping the "--" in a <span/> (e.g. <span id="answerDisplay">--</span>). Then use document.getElementById("answerDisplay").textContent = answer; to display it.

There is a similar question Extract main domain name from a given url. If you take a look at this answer , you will see that it is very easy. You just need to use java.net.URL and String utility - Split

In order to create an array of objects, the objects need a constructor that doesn't take any paramters (that creates a default form of the object, eg. with both strings empty). This is what the error message means. The compiler automatically generates a constructor which creates an empty object unless there are any other constructors.

If it makes sense for the array elements to be created empty (in which case the members acquire their default values, in this case, empty strings), you should:

-Write an empty constructor:

class name {
  public:
    string first;
    string last;

  name() { }
  name(string a, string b){
    first = a;
    last = b;
  }
};

-Or, if you don't need it, remove the existing constructor.

If an "empty" version of your class makes no sense, there is no good solution to provide initialisation paramters to all the elements of the array at compile time. You can:

• Have a constructor create an empty version of the class anyway, and an init() function which does the real initialisation
• Use a vector, and on initialisation create the objects and insert them into the vector, either using vector::insert or a loop, and trust that not doing it at compile time doesn't matter.
• If the object can't be copied either, you can use an array/vector of smart pointers to the object and allocate them on initialisation.
• If you can use C++11 I think (?) you can use initialiser lists to initialise a vector and intialise it (I'm not sure if that works with any contructor or only if the object is created from a single value of another type). Eg: .

 std::vector<std::string> v = { "xyzzy", "plugh", "abracadabra" };

How to change commits deeper in history

Since history in Git is immutable, fixing anything but the most recent commit (commit which is not branch head) requires that the history is rewritten from the changed commit and forward.

You can use StGIT for that, initialize branch if necessary, uncommitting up to the commit you want to change, pop to it if necessary, make a change then refresh patch (with -e option if you want to correct commit message), then push everything and stg commit.

Or you can use rebase to do that. Create new temporary branch, rewind it to the commit you want to change using git reset --hard, change that commit (it would be top of current head), then rebase branch on top of changed commit, using git rebase --onto .

Or you can use git rebase --interactive, which allows various modifications like patch re-ordering, collapsing, ...

I think that should answer your question. However, note that if you have pushed code to a remote repository and people have pulled from it, then this is going to mess up their code histories, as well as the work they've done. So do it carefully.

The function you need is CInt.

ie CInt(PrinterLabel)

See Type Conversion Functions (Visual Basic) on MSDN

Edit: Be aware that CInt and its relatives behave differently in VB.net and VBScript. For example, in VB.net, CInt casts to a 32-bit integer, but in VBScript, CInt casts to a 16-bit integer. Be on the lookout for potential overflows!

Use Console.ReadLine() at the end of the program. This will keep the window open until you press the Enter key. See https://docs.microsoft.com/en-us/dotnet/api/system.console.readline for details.

For length including white-space:

$("#id").val().length

For length without white-space:

$("#id").val().replace(/ /g,'').length

For removing only beginning and trailing white-space:

$.trim($("#test").val()).length

For example, the string " t e s t " would evaluate as:

//" t e s t "
$("#id").val(); 

//Example 1
$("#id").val().length; //Returns 9
//Example 2
$("#id").val().replace(/ /g,'').length; //Returns 4
//Example 3
$.trim($("#test").val()).length; //Returns 7

Here is a demo using all of them.

This error occurs in angular when you didn't intialise the array blank.
For an example:

userlist: any[ ];
this.userlist = [ ]; 

or

userlist: any = [ ];

You can go to...

\node_modules\metro-config\src\defaults\blacklist.js and change...

var sharedBlacklist = [   /node_modules[/\\]react[/\\]dist[/\\].*/,  
/website\/node_modules\/.*/,   /heapCapture\/bundle\.js/,  
/.*\/__tests__\/.*/ ];

for this:

var sharedBlacklist = [
  /node_modules[\/\\]react[\/\\]dist[\/\\].*/,
  /website\/node_modules\/.*/,
  /heapCapture\/bundle\.js/,
  /.*\/__tests__\/.*/
];

You can do it with cut:

cut -d " " -f 3- input_filename > output_filename

Explanation:

• cut: invoke the cut command
• -d " ": use a single space as the delimiter (cut uses TAB by default)
• -f: specify fields to keep
• 3-: all the fields starting with field 3
• input_filename: use this file as the input
• > output_filename: write the output to this file.

Alternatively, you can do it with awk:

awk '{$1=""; $2=""; sub("  ", " "); print}' input_filename > output_filename

Explanation:

• awk: invoke the awk command
• $1=""; $2="";: set field 1 and 2 to the empty string
• sub(...);: clean up the output fields because fields 1 & 2 will still be delimited by " "
• print: print the modified line
• input_filename > output_filename: same as above.

JObjects can be enumerated via JProperty objects by casting it to a JToken:

foreach (JProperty x in (JToken)obj) { // if 'obj' is a JObject
    string name = x.Name;
    JToken value = x.Value;
}

If you have a nested JObject inside of another JObject, you don't need to cast because the accessor will return a JToken:

foreach (JProperty x in obj["otherObject"]) { // Where 'obj' and 'obj["otherObject"]' are both JObjects
    string name = x.Name;
    JToken value = x.Value;
}

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

You're trying to update the record (which to me means "change a value on an existing record and save it back"). So you need to retrieve the object, make a change, and save it.

using (var db = new MyContextDB())
{
    var result = db.Books.SingleOrDefault(b => b.BookNumber == bookNumber);
    if (result != null)
    {
        result.SomeValue = "Some new value";
        db.SaveChanges();
    }
}

First, I recommend that you use WCF, .NET Remoting, or some other higher-level communication abstraction. The learning curve for "simple" sockets is nearly as high as WCF, because there are so many non-obvious pitfalls when using TCP/IP directly.

If you decide to continue down the TCP/IP path, then review my .NET TCP/IP FAQ, particularly the sections on message framing and application protocol specifications.

Also, use asynchronous socket APIs. The synchronous APIs do not scale and in some error situations may cause deadlocks. The synchronous APIs make for pretty little example code, but real-world production-quality code uses the asynchronous APIs.

You didn't explicitly state emacs, but since you've highlighted lots of editors...

In emacs, you can use rectangles for this, where a column is a rectangle of width 1.

To create a rectangle, mark the top-left and bottom-right of the rectangle (where the bottom-right mark is one to the right of the further right point included in the rectangle. You can then manipulate via:

C-x r k
Kill the text of the region-rectangle, saving its contents as the "last killed rectangle" (kill-rectangle).

C-x r d
Delete the text of the region-rectangle (delete-rectangle).

C-x r y
Yank the last killed rectangle with its upper left corner at point (yank-rectangle).

C-x r o
Insert blank space to fill the space of the region-rectangle (open-rectangle). This pushes the previous contents of the region-rectangle rightward.

M-x clear-rectangle
Clear the region-rectangle by replacing its contents with spaces.

M-x delete-whitespace-rectangle
Delete whitespace in each of the lines on the specified rectangle, starting from the left edge column of the rectangle.

C-x r t string RET
Replace rectangle contents with string on each line. (string-rectangle).

M-x string-insert-rectangle RET string RET
Insert string on each line of the rectangle.

Set the JAVA_HOME pointing to the java version you want.

JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64

Problem comes from the fact that line breaks (\n\r?) are not the same as HTML <br/> tags

var text = document.forms[0].txt.value;
text = text.replace(/\r?\n/g, '<br />');

UPDATE

Since many of the comments and my own experience have show me that this <br> solution is not working as expected here is an example of how to append a new line to a textarea using '\r\n'

function log(text) {
    var txtArea ;

    txtArea = document.getElementById("txtDebug") ;
    txtArea.value +=  text + '\r\n';
}

I decided to do this an edit, and not as a new question because this a far too popular answer to be wrong or incomplete.

Use find on the command line:

find /my/directory -name '*.js'

You don't need any tool. Only a few clicks.

Windows 10 can handle ttc files with no problem.

You can double click the file and install it like any ttf. Then if you nead the individual ttf files you can go to C:\Windows\Fonts\Font Name and there you will findit. If you cant do this i suspect you have a corupt file.

If you are using Ubuntu many distros the notify-send command will throw one of those nice perishable notifications in the top right corner. Like so:

Apart from using JSoup, we can alternatively do pattern matching for getting the app version from playStore.

To match the latest pattern from google playstore ie <div class="BgcNfc">Current Version</div><span class="htlgb"><div><span class="htlgb">X.X.X</span></div> we first have to match the above node sequence and then from above sequence get the version value. Below is the code snippet for same:

    private String getAppVersion(String patternString, String inputString) {
        try{
            //Create a pattern
            Pattern pattern = Pattern.compile(patternString);
            if (null == pattern) {
                return null;
            }

            //Match the pattern string in provided string
            Matcher matcher = pattern.matcher(inputString);
            if (null != matcher && matcher.find()) {
                return matcher.group(1);
            }

        }catch (PatternSyntaxException ex) {

            ex.printStackTrace();
        }

        return null;
    }


    private String getPlayStoreAppVersion(String appUrlString) {
        final String currentVersion_PatternSeq = "<div[^>]*?>Current\\sVersion</div><span[^>]*?>(.*?)><div[^>]*?>(.*?)><span[^>]*?>(.*?)</span>";
        final String appVersion_PatternSeq = "htlgb\">([^<]*)</s";
        String playStoreAppVersion = null;

        BufferedReader inReader = null;
        URLConnection uc = null;
        StringBuilder urlData = new StringBuilder();

        final URL url = new URL(appUrlString);
        uc = url.openConnection();
        if(uc == null) {
           return null;
        }
        uc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; WindowsNT 5.1; en-US; rv1.8.1.6) Gecko/20070725 Firefox/2.0.0.6");
        inReader = new BufferedReader(new InputStreamReader(uc.getInputStream()));
        if (null != inReader) {
            String str = "";
            while ((str = inReader.readLine()) != null) {
                           urlData.append(str);
            }
        }

        // Get the current version pattern sequence 
        String versionString = getAppVersion (currentVersion_PatternSeq, urlData.toString());
        if(null == versionString){ 
            return null;
        }else{
            // get version from "htlgb">X.X.X</span>
            playStoreAppVersion = getAppVersion (appVersion_PatternSeq, versionString);
        }

        return playStoreAppVersion;
    }

I got it solved through this, as this works for latest Google playstore changes also. Hope that helps.

• You cannot change the color in cdn file.
• Download the bootstrap file.
• Search For bootstrap.css file.
• open this(bootstrsap.css) file and search for 'primary'.
• change it to the colour you desire.

Here is another simple answer, but without using classes.

You can't remove items from a list while iterating over it. It's much easier to build a new list based on the old one:

y = [s for s in x if len(s) == 2]

The Thread class is used for creating and manipulating a thread in Windows.

A Task represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.

In the days of old (i.e. before TPL) it used to be that using the Thread class was one of the standard ways to run code in the background or in parallel (a better alternative was often to use a ThreadPool), however this was cumbersome and had several disadvantages, not least of which was the performance overhead of creating a whole new thread to perform a task in the background.

Nowadays using tasks and the TPL is a far better solution 90% of the time as it provides abstractions which allows far more efficient use of system resources. I imagine there are a few scenarios where you want explicit control over the thread on which you are running your code, however generally speaking if you want to run something asynchronously your first port of call should be the TPL.

I belive you can use

rm -v !(filename)

Except for the filename all the other files will e deleted in the directory and make sure you are using it in

Using the hyperref package, you could also declare a new command by using \newcommand{\secref}[1]{\autoref{#1}. \nameref{#1}} in the pre-amble. Placing \secref{section:my} in the text generates: 1. My section.

ogdate is itself a string, why are you trying to access it's value property that it doesn't have ?

console.log(og_date.split('-'));

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">

By the way, if you happen to know that it is connected, then simply it is a tree (thus no cycles) if and only if |E|=|V|-1. Of course that's not a small amount of information :)

In my case I had a class that had a method and a string property of the same name, I was trying to call the method but was getting the string property.

Having had a similar problem with data from 1800 to now, this worked for me:

data2$date=as.character(data2$date) 
lct <- Sys.getlocale("LC_TIME"); 
Sys.setlocale("LC_TIME","C")
data2$date<- as.Date(data2$date, format = "%Y %m %d") # and it works

For just reading the last element of a slice:

sl[len(sl)-1]

For removing it:

sl = sl[:len(sl)-1]

Before new gallery access in KitKat I got my real path in sdcard with this method

That was never reliable. There is no requirement that the Uri that you are returned from an ACTION_GET_CONTENT or ACTION_PICK request has to be indexed by the MediaStore, or even has to represent a file on the file system. The Uri could, for example, represent a stream, where an encrypted file is decrypted for you on the fly.

How could I manage to obtain the real path in sdcard?

There is no requirement that there is a file corresponding to the Uri.

Yes, I really need a path

Then copy the file from the stream to your own temporary file, and use it. Better yet, just use the stream directly, and avoid the temporary file.

I have changed my Intent.ACTION_GET_CONTENT for Intent.ACTION_PICK

That will not help your situation. There is no requirement that an ACTION_PICK response be for a Uri that has a file on the filesystem that you can somehow magically derive.

you can try chsh -s /bin/bash to set the bash as the default, or chsh -s /bin/zsh to set the zsh as the default.

Terminal will need a restart to take effect.

There are couple of different solutions to achieve this:

1 - Native javascript for-in loop:

const result = {};
let key;

for (key in obj1) {
  if(obj1.hasOwnProperty(key)){
    result[key] = obj1[key];
  }
}

for (key in obj2) {
  if(obj2.hasOwnProperty(key)){
    result[key] = obj2[key];
  }
}

2 - Object.keys():

const result = {};

Object.keys(obj1)
  .forEach(key => result[key] = obj1[key]);

Object.keys(obj2)
  .forEach(key => result[key] = obj2[key]);

3 - Object.assign():
(Browser compatibility: Chrome: 45, Firefox (Gecko): 34, Internet Explorer: No support, Edge: (Yes), Opera: 32, Safari: 9)

const result = Object.assign({}, obj1, obj2);

4 - Spread Operator:
Standardised from ECMAScript 2015 (6th Edition, ECMA-262):

Defined in several sections of the specification: Array Initializer, Argument Lists

Using this new syntax you could join/merge different objects into one object like this:

const result = {
  ...obj1,
  ...obj2,
};

5 - jQuery.extend(target, obj1, obj2):

Merge the contents of two or more objects together into the first object.

const target = {};

$.extend(target, obj1, obj2);

6 - jQuery.extend(true, target, obj1, obj2):

Run a deep merge of the contents of two or more objects together into the target. Passing false for the first argument is not supported.

const target = {};

$.extend(true, target, obj1, obj2);

7 - Lodash _.assignIn(object, [sources]): also named as _.extend:

const result = {};

_.assignIn(result, obj1, obj2);

8 - Lodash _.merge(object, [sources]):

const result = _.merge(obj1, obj2);

There are a couple of important differences between lodash's merge function and Object.assign:

1- Although they both receive any number of objects but lodash's merge apply a deep merge of those objects but Object.assign only merges the first level. For instance:

_.isEqual(_.merge({
  x: {
    y: { key1: 'value1' },
  },
}, {
  x: {
    y: { key2: 'value2' },
  },
}), {
  x: {
    y: {
      key1: 'value1',
      key2: 'value2',
    },
  },
}); // true

BUT:

const result = Object.assign({
  x: {
    y: { key1: 'value1' },
  },
}, {
  x: {
    y: { key2: 'value2' },
  },
});
_.isEqual(result, {
  x: {
    y: {
      key1: 'value1',
      key2: 'value2',
    },
  },
}); // false
// AND
_.isEqual(result, {
  x: {
    y: {
      key2: 'value2',
    },
  },
}); // true

2- Another difference has to do with how Object.assign and _.merge interpret the undefined value:

_.isEqual(_.merge({x: 1}, {x: undefined}), { x: 1 }) // false

BUT:

_.isEqual(Object.assign({x: 1}, {x: undefined}), { x: undefined })// true

Update 1:

When using for in loop in JavaScript, we should be aware of our environment specially the possible prototype changes in the JavaScript types. For instance some of the older JavaScript libraries add new stuff to Array.prototype or even Object.prototype. To safeguard your iterations over from the added stuff we could use object.hasOwnProperty(key) to mke sure the key is actually part of the object you are iterating over.

Update 2:

I updated my answer and added the solution number 4, which is a new JavaScript feature but not completely standardized yet. I am using it with Babeljs which is a compiler for writing next generation JavaScript.

Update 3:
I added the difference between Object.assign and _.merge.

Here is what i did

 int color=//your color
 Integer.toHexString(color).toUpperCase();//upercase with alpha
 Integer.toHexString(color).toUpperCase().substring(2);// uppercase without alpha

Thanks guys you answers did the thing

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

Go to the language settings in the Control Panel, then Format Options, select a locale and see the actual date format for the chosen locale used by Windows by default. Yes, that timestamp format is locale-sensitive. Excel uses those formats when parsing CSV.

Even further, if the locale uses characters beyond ASCII, you'll have to emit CSV in the corresponding pre-Unicode Windows "ANSI" codepage, e.g. CP1251. Excel won't accept UTF-8.

Late reply, but adding that Mongoose also has the concept of Subdocuments

With this syntax, you should be able to reference your userSchema as a type in your postSchema like so:

var userSchema = new Schema({
    twittername: String,
    twitterID: Number,
    displayName: String,
    profilePic: String,
});

var postSchema = new Schema({
    name: String,
    postedBy: userSchema,
    dateCreated: Date,
    comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});

Note the updated postedBy field with type userSchema.

This will embed the user object within the post, saving an extra lookup required by using a reference. Sometimes this could be preferable, other times the ref/populate route might be the way to go. Depends on what your application is doing.

--reverse is also helpful since you want the first commit that made the change:

git log --all -p --reverse --source -S 'needle'

This way older commits will appear first.

$ whereis java

java: /usr/bin/java /usr/lib/java /usr/bin/X11/java /usr/share/java /usr/share/man/man1/java.1.gz

First, you'll need to add session_start() at the top of any page that you wish to use SESSION variables on.

Also, you should check to make sure the variable is set first before using it:

if(isset($_SESSION['SESS_fname'])){
    echo $_SESSION['SESS_fname'];
}

Or, simply:

echo (isset($_SESSION['SESS_fname']) ? $_SESSION['SESS_fname'] : "Visitor");

I did a quick non-scientific test in Release mode. I used two inputs: "2.34523" and "badinput" into both methods and iterated 1,000,000 times.

Valid input:

Double.TryParse = 646ms
Convert.ToDouble = 662 ms

Not much different, as expected. For all intents and purposes, for valid input, these are the same.

Invalid input:

Double.TryParse = 612ms
Convert.ToDouble = ..

Well.. it was running for a long time. I reran the entire thing using 1,000 iterations and Convert.ToDouble with bad input took 8.3 seconds. Averaging it out, it would take over 2 hours. I don't care how basic the test is, in the invalid input case, Convert.ToDouble's exception raising will ruin your performance.

So, here's another vote for TryParse with some numbers to back it up.

You can use

$objWorksheet->getActiveSheet()->getRowDimension('1')->setRowHeight(40);
$objWorksheet->getActiveSheet()->getColumnDimension('A')->setWidth(100);

or define auto-size:

$objWorksheet->getRowDimension('1')->setRowHeight(-1);

To make it more clear(and to put it together) I had to do Two things mentioned above.

1- Create a file /etc/ld.so.conf.d/opencv.conf and write to it the paths of folder where your opencv libraries are stored.(Answer by Cookyt)

2- Include the path of your opencv's .so files in LD_LIBRARY_PATH ()

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/opencv/lib

Ctrl + F12 also works well on linux(ubuntu).

If somebody is seeking to update data from one database to another no matter which table they are targeting, there must be some criteria to do it.

This one is better and clean for all levels:

UPDATE dbname1.content targetTable

LEFT JOIN dbname2.someothertable sourceTable ON
    targetTable.compare_field= sourceTable.compare_field
SET
    targetTable.col1  = sourceTable.cola,
    targetTable.col2 = sourceTable.colb, 
    targetTable.col3 = sourceTable.colc, 
    targetTable.col4 = sourceTable.cold 

Traaa! It works great!

With the above understanding, you can modify the set fields and "on" criteria to do your work. You can also perform the checks, then pull the data into the temp table(s) and then run the update using the above syntax replacing your table and column names.

Hope it works, if not let me know. I will write an exact query for you.

I translated the Python code to C. The example given had a minor flaw. If the dividend value that took up all the 32 bits, the shift would fail. I just used 64-bit variables internally to work around the problem:

int No_divide(int nDivisor, int nDividend, int *nRemainder)
{
    int nQuotient = 0;
    int nPos = -1;
    unsigned long long ullDivisor = nDivisor;
    unsigned long long ullDividend = nDividend;

    while (ullDivisor <  ullDividend)
    {
        ullDivisor <<= 1;
        nPos ++;
    }

    ullDivisor >>= 1;

    while (nPos > -1)
    {
        if (ullDividend >= ullDivisor)
        {
            nQuotient += (1 << nPos);
            ullDividend -= ullDivisor;
        }

        ullDivisor >>= 1;
        nPos -= 1;
    }

    *nRemainder = (int) ullDividend;

    return nQuotient;
}

In your components.module.ts you should import IonicModule like this:

import { IonicModule } from '@ionic/angular';

Then import IonicModule like this:

  imports: [
    CommonModule,
    IonicModule
  ],

so your components.module.ts will be like this:

import { CommonModule } from '@angular/common';
import {PostComponent} from './post/post.component'
import { IonicModule } from '@ionic/angular';

@NgModule({
  declarations: [PostComponent],
  imports: [
    CommonModule,
    IonicModule
  ],
  exports: [PostComponent]
})
export class ComponentsModule { }```

CORS (Cross-Origin Resource Sharing) and SOP (Same-Origin Policy) are server-side configurations that clients decide to enforce or not.

Related to clients

• Most Browsers do enforce it to prevent issues related to CSRF attack.
• Most Development tools don't care about it.

When you import a module (or a member of it) for the first time, the code inside the module is executed sequentially like any other code; e.g., it is not treated any differently that the body of a function. An import is just a command like any other (assignment, a function call, def, class). Assuming your imports occur at the top of the script, then here's what's happening:

• When you try to import World from world, the world script gets executed.
• The world script imports Field, which causes the entities.field script to get executed.
• This process continues until you reach the entities.post script because you tried to import Post
• The entities.post script causes physics module to be executed because it tries to import PostBody
• Finally, physics tries to import Post from entities.post
• I'm not sure whether the entities.post module exists in memory yet, but it really doesn't matter. Either the module is not in memory, or the module doesn't yet have a Post member because it hasn't finished executing to define Post
• Either way, an error occurs because Post is not there to be imported

So no, it's not "working further up in the call stack". This is a stack trace of where the error occurred, which means it errored out trying to import Post in that class. You shouldn't use circular imports. At best, it has negligible benefit (typically, no benefit), and it causes problems like this. It burdens any developer maintaining it, forcing them to walk on egg shells to avoid breaking it. Refactor your module organization.

As a string is a collection of characters, you can use LINQ extension methods on them:

if (s.Any(c => c == 'a' || c == 'b' || c == 'c')) ...

This will scan the string once and stop at the first occurance, instead of scanning the string once for each character until a match is found.

This can also be used for any expression you like, for example checking for a range of characters:

if (s.Any(c => c >= 'a' && c <= 'c')) ...

visualize the rolling averages to see if it makes sense. I don't understand why sum was used when the rolling average was requested.

  df=pd.read_csv('poll.csv',parse_dates=['enddate'],dtype={'favorable':np.float,'unfavorable':np.float,'other':np.float})

  df.set_index('enddate')
  df=df.fillna(0)

 fig, axs = plt.subplots(figsize=(5,10))
 df.plot(x='enddate', ax=axs)
 plt.show()


 df.rolling(window=3,min_periods=3).mean().plot()
 plt.show()
 print("The larger the window coefficient the smoother the line will appear")
 print('The min_periods is the minimum number of observations in the window required to have a value')

 df.rolling(window=6,min_periods=3).mean().plot()
 plt.show()

You are using improper syntax. If you read the docs mysqli_query() you will find that it needs two parameter.

mixed mysqli_query ( mysqli $link , string $query [, int $resultmode = MYSQLI_STORE_RESULT ] )

mysql $link generally means, the resource object of the established mysqli connection to query the database.

So there are two ways of solving this problem

mysqli_query();

$myConnection= mysqli_connect("$db_host","$db_username","$db_pass", "mrmagicadam") or die ("could not connect to mysql"); 
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysqli_query($myConnection, $sqlCommand) or die(mysqli_error($myConnection));

Or, Using mysql_query() (This is now obselete)

$myConnection= mysql_connect("$db_host","$db_username","$db_pass") or die ("could not connect to mysql");
mysql_select_db("mrmagicadam") or die ("no database");        
$sqlCommand="SELECT id, linklabel FROM pages ORDER BY pageorder ASC";
$query=mysql_query($sqlCommand) or die(mysql_error());

As pointed out in the comments, be aware of using die to just get the error. It might inadvertently give the viewer some sensitive information .

Also echo json_encode($dataobject); might be helpful

I have philosophical problems with the use of exceptions. Basically, you are expecting a specific scenario to occur, but rather than handling it explicitly you are pushing the problem off to be handled "elsewhere." And where that "elsewhere" is can be anyone's guess.

In the case where the process was spawned by another node process, like:

var child = spawn('gulp', ['watch'], {
    stdio: 'inherit',
});

And you try to kill it later, via:

child.kill();

This is how you handle the event [on the child]:

process.on('SIGTERM', function() {
    console.log('Goodbye!');
});

You can use

<input name="Upload Saved Replay" type="file" 
  accept="application/pdf,application/msword,
  application/vnd.openxmlformats-officedocument.wordprocessingml.document"/>

whearat

• application/pdf means .pdf
• application/msword means .doc
• application/vnd.openxmlformats-officedocument.wordprocessingml.document means .docx

instead.

[EDIT] Be warned, .dot might match too.

We don't have option to truncate dynamo tables. we have to drop the table and create again . DynamoDB Charges are based on ReadCapacityUnits & WriteCapacityUnits . If we delete all items using BatchWriteItem function, it will use WriteCapacityUnits.So better to delete specific records or delete the table and start again .

For those looking for a modern solution that works in IE, Firefox, AND Chrome:

None of these solutions that use a hyperlink element will work the same in chrome. If you pass an invalid (or blank) url to chrome, it will always return the host where the script is called from. So in IE you will get blank, whereas in Chrome you will get localhost (or whatever).

If you are trying to look at the referrer, this is deceitful. You will want to make sure that the host you get back was in the original url to deal with this:

    function getHostNameFromUrl(url) {
        // <summary>Parses the domain/host from a given url.</summary>
        var a = document.createElement("a");
        a.href = url;

        // Handle chrome which will default to domain where script is called from if invalid
        return url.indexOf(a.hostname) != -1 ? a.hostname : '';
    }

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

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

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

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

function fn_DateCompare(DateA, DateB) {     // this function is good for dates > 01/01/1970

    var a = new Date(DateA);
    var b = new Date(DateB);

    var msDateA = Date.UTC(a.getFullYear(), a.getMonth()+1, a.getDate());
    var msDateB = Date.UTC(b.getFullYear(), b.getMonth()+1, b.getDate());

    if (parseFloat(msDateA) < parseFloat(msDateB))
      return -1;  // lt
    else if (parseFloat(msDateA) == parseFloat(msDateB))
      return 0;  // eq
    else if (parseFloat(msDateA) > parseFloat(msDateB))
      return 1;  // gt
    else
      return null;  // error
}

Use the Character.toString() method like so:

char mChar = 'l';
String s = Character.toString(mChar);

Active directory is a directory service provider, where you can add new user to a directory, remove or modify, specify privilages, assign policy etc. Its just like a phone directory where every person have a unique contact number. Every thing in AD(Active Directory) are considered as Objects and every object is given a Unique ID.(similar to a unique contact number in a phone directory.

Ldap is a protocol specially designed for directory service providers. Windows server OS uses AD as a directory server, AIX which is a UNIX version by IBM uses Tivoli directory server. Both of them uses LDAP protocol for interacting with directory.

Apart from protocol there are LDAP servers, LDAP browsers too.

You have to perform the GridView1.Columns[i].Visible = false; after the grid has been databound.

Just coerce the StatusCode to int.

var statusNumber;
try {
   response = (HttpWebResponse)request.GetResponse();
   // This will have statii from 200 to 30x
   statusNumber = (int)response.StatusCode;
}
catch (WebException we) {
    // Statii 400 to 50x will be here
    statusNumber = (int)we.Response.StatusCode;
}

I found the problem. Instead of adding a class (.cs) file by mistake I had added a Web API Controller class which added a configuration file in my solution. And that configuration file was looking for the mentioned DLL (Microsoft.Web.Infrastructure 1.0.0.0). It worked when I removed that file, cleaned the application and then published.
