With the course of : TestMyCode Programming assignment evaluator, that one of the exercises was this kind of issue, I wrote this answer:

import java.util.Scanner;

public class LeapYear {

    public static void main(String[] args) {
        Scanner reader = new Scanner(System.in);
        System.out.println("Type a year: ");

        int year = Integer.parseInt(reader.nextLine());

        if (year % 400 == 0 && year % 100 == 0 && year % 4 == 0) {
            System.out.println("The year is a leap year");
        } else
         if (year % 4 == 0 && year%100!=0 ) {
            System.out.println("The year is a leap year");
        } else 
        {
            System.out.println("The year is not a leap year");
        }

    }
}

I haven't done this, so I'm just going to point at the right answer.

C has provisions for functions that take unspecified numbers of operands, using the <stdarg.h> header. You can define your function as void log_out(const char *fmt, ...);, and get the va_list inside the function. Then you can allocate memory and call vsprintf() with the allocated memory, format, and va_list.

Alternately, you could use this to write a function analogous to sprintf() that would allocate memory and return the formatted string, generating it more or less as above. It would be a memory leak, but if you're just logging out it may not matter.

Python variables are scoped to the innermost function, class, or module in which they're assigned. Control blocks like if and while blocks don't count, so a variable assigned inside an if is still scoped to a function, class, or module.

(Implicit functions defined by a generator expression or list/set/dict comprehension do count, as do lambda expressions. You can't stuff an assignment statement into any of those, but lambda parameters and for clause targets are implicit assignment.)

The advantage of lists appears if you need to insert items in the middle and don't want to start resizing the array and shifting things around.

You're correct in that this is typically not the case. I've had a few very specific cases like that, but not too many.

var ItemSchema = new Schema({
    name : { type: String, required: true, trim: true }
});

ItemSchema.set('timestamps', true); // this will add createdAt and updatedAt timestamps

To make it simple, let us say that we can use constructor based dependency injection for mandatory dependencies and setter based injection for optional dependencies. It is a rule of thumb!!

Let's say for example.

If you want to instantiate a class you always do it with its constructor. So if you are using constructor based injection, the only way to instantiate the class is through that constructor. If you pass the dependency through constructor it becomes evident that it is a mandatory dependency.

On the other hand, if you have a setter method in a POJO class, you may or may not set value for your class variable using that setter method. It is completely based on your need. i.e. it is optional. So if you pass the dependency through setter method of a class it implicitly means that it is an optional dependency. Hope this is clear!!

In a recent application that I made, I used the inverted colors. With the r,g and b values in hand, just calculate (in this example, the color range varies from 0 to 255) :

r = 127-(r-127) and so on.

strToLower should return a char * instead of a char. Something like this would do.

char *strToLower(char *cString)

I made a thing that doesn't break the existing Storage objects, but creates a wrapper so you can do what you want. The result is a normal object, no methods, with access like any object.

The thing I made.

If you want 1 localStorage property to be magic:

var prop = ObjectStorage(localStorage, 'prop');

If you need several:

var storage = ObjectStorage(localStorage, ['prop', 'more', 'props']);

Everything you do to prop, or the objects inside storage will be automatically saved into localStorage. You're always playing with a real object, so you can do stuff like this:

storage.data.list.push('more data');
storage.another.list.splice(1, 2, {another: 'object'});

And every new object inside a tracked object will be automatically tracked.

The very big downside: it depends on Object.observe() so it has very limited browser support. And it doesn't look like it'll be coming for Firefox or Edge anytime soon.

Check openssl tool which is a collection of Openssl from the LibreSSL project and Cygwin libraries (2.5 MB). NB! We're the packager.

One liner to create a self signed certificate:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout selfsigned.key -out selfsigned.crt

Sometimes you want to change the capitalization of a lot of file names on a case insensitive filesystem (e.g. on OS X or Windows). Doing git mv commands will tire quickly. To make things a bit easier this is what I do:

1. Move all files outside of the directory to, let’s, say the desktop.
2. Do a git add . -A to remove all files.
3. Rename all files on the desktop to the proper capitalization.
4. Move all the files back to the original directory.
5. Do a git add .. Git should see that the files are renamed.

Now you can make a commit saying you have changed the file name capitalization.

kangax's solution introduces unnecessary try..catch scope. If you need to access the line number of something in JavaScript (as long as you are using Firefox or Opera), just access (new Error).lineNumber.

Even in spite of being final a field can be modified outside of static initializer and (at least JVM HotSpot) will execute the bytecode perfectly fine.

The problem is that Java compiler does not allow this, but this can be easily bypassed using objectweb.asm. Here is p?e?r?f?e?c?t?l?y? ?v?a?l?i?d? ?c?l?a?s?s?f?i?l?e? an invalid classfile from the JVMS specification standpoint, but it passes bytecode verification and then is successfully loaded and initialized under JVM HotSpot OpenJDK12:

ClassWriter cw = new ClassWriter(0);
cw.visit(Opcodes.V1_8, Opcodes.ACC_PUBLIC, "Cl", null, "java/lang/Object", null);
{
    FieldVisitor fv = cw.visitField(Opcodes.ACC_PRIVATE | Opcodes.ACC_STATIC | Opcodes.ACC_FINAL, "fld", "I", null, null);
    fv.visitEnd();
}
{
    // public void setFinalField1() { //... }
    MethodVisitor mv = cw.visitMethod(Opcodes.ACC_PUBLIC | Opcodes.ACC_STATIC, "setFinalField1", "()V", null, null);
    mv.visitMaxs(2, 1);
    mv.visitInsn(Opcodes.ICONST_5);
    mv.visitFieldInsn(Opcodes.PUTSTATIC, "Cl", "fld", "I");
    mv.visitInsn(Opcodes.RETURN);
    mv.visitEnd();
}
{
    // public void setFinalField2() { //... }
    MethodVisitor mv = cw.visitMethod(Opcodes.ACC_PUBLIC | Opcodes.ACC_STATIC, "setFinalField2", "()V", null, null);
    mv.visitMaxs(2, 1);
    mv.visitInsn(Opcodes.ICONST_2);
    mv.visitFieldInsn(Opcodes.PUTSTATIC, "Cl", "fld", "I");
    mv.visitInsn(Opcodes.RETURN);
    mv.visitEnd();
}
cw.visitEnd();

In Java, the class looks roughly speaking as follows:

public class Cl{
    private static final int fld;

    public static void setFinalField1(){
        fld = 5;
    }

    public static void setFinalField2(){
        fld = 2;
    }
}

which cannot be compiled with javac, but can be loaded and executed by JVM.

JVM HotSpot has special treatment of such classes in the sense that it prevents such "constants" from participating in constant folding. This check is done on the bytecode rewriting phase of class initialization:

// Check if any final field of the class given as parameter is modified
// outside of initializer methods of the class. Fields that are modified
// are marked with a flag. For marked fields, the compilers do not perform
// constant folding (as the field can be changed after initialization).
//
// The check is performed after verification and only if verification has
// succeeded. Therefore, the class is guaranteed to be well-formed.
InstanceKlass* klass = method->method_holder();
u2 bc_index = Bytes::get_Java_u2(bcp + prefix_length + 1);
constantPoolHandle cp(method->constants());
Symbol* ref_class_name = cp->klass_name_at(cp->klass_ref_index_at(bc_index));
if (klass->name() == ref_class_name) {
   Symbol* field_name = cp->name_ref_at(bc_index);
   Symbol* field_sig = cp->signature_ref_at(bc_index);

   fieldDescriptor fd;
   if (klass->find_field(field_name, field_sig, &fd) != NULL) {
      if (fd.access_flags().is_final()) {
         if (fd.access_flags().is_static()) {
            if (!method->is_static_initializer()) {
               fd.set_has_initialized_final_update(true);
            }
          } else {
            if (!method->is_object_initializer()) {
              fd.set_has_initialized_final_update(true);
            }
          }
        }
      }
    }
}

The only restriction that JVM HotSpot checks is that the final field should not be modified outside of the class that the final field is declared at.

MainActivity.java:

package com.example.andreaskonstantakos.vfy;


import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import com.google.android.youtube.player.YouTubeBaseActivity;
import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayerView;



public class MainActivity extends YouTubeBaseActivity {

YouTubePlayerView youTubePlayerView;
Button button;
YouTubePlayer.OnInitializedListener onInitializedListener;

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

     youTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player);

            public void onClick(View v) {

youTubePlayerView.initialize(PlayerConfig.API_KEY,onInitializedListener);
        }
    });
}
}

and the PlayerConfig.java class:

    package com.example.andreaskonstantakos.vfy;

/**
 * Created by Andreas Konstantakos on 13/4/2017.
 */

public class PlayerConfig {

PlayerConfig(){}

public static final String API_KEY = 
"xxxxx";
}

Replace the "Hce74cEAAaE" with your video ID from https://www.youtube.com/watch?v=Hce74cEAAaE. Get your API_KEY from Console.developers.google.com and also replace it on the PlayerConfig.API_KEY. For any further information you can follow the following tutorial step by step: https://www.youtube.com/watch?v=3LiubyYpEUk

use moment in your function like this

 moment(new Date(date)).format('MM/DD/YYYY')

As Ayman farhat mentioned you can use the simple method len(matrix) to get the length of rows and get the length of the first row to get the no. of columns using len(matrix[0]) :

>>> a=[[1,5,6,8],[1,2,5,9],[7,5,6,2]]
>>> len(a)
3
>>> len(a[0])
4

Also you can use a library that helps you with matrices "numpy":

>>> import numpy 
>>> numpy.shape(a)
(3,4)

It is possible to define a function from inside another function. the inner function does not exist until the outer function gets executed.

echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';
$x=x(2);
echo function_exists("y") ? 'y is defined\n' : 'y is not defined \n';

Output

y is not defined

y is defined

Simple thing you can not call function y before executed x

Alternate solution by using JobScheduler, it can start service in background in regular interval of time.

Firstly make class named as Util.java

import android.app.job.JobInfo;
import android.app.job.JobScheduler;
import android.content.ComponentName;
import android.content.Context;

public class Util {
// schedule the start of the service every 10 - 30 seconds
public static void schedulerJob(Context context) {
    ComponentName serviceComponent = new ComponentName(context,TestJobService.class);
    JobInfo.Builder builder = new JobInfo.Builder(0,serviceComponent);
    builder.setMinimumLatency(1*1000);    // wait at least
    builder.setOverrideDeadline(3*1000);  //delay time
    builder.setRequiredNetworkType(JobInfo.NETWORK_TYPE_UNMETERED);  // require unmetered network
    builder.setRequiresCharging(false);  // we don't care if the device is charging or not
    builder.setRequiresDeviceIdle(true); // device should be idle
    System.out.println("(scheduler Job");

    JobScheduler jobScheduler = null;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.M) {
        jobScheduler = context.getSystemService(JobScheduler.class);
    }
    jobScheduler.schedule(builder.build());
   }
  }

Then, make JobService class named as TestJobService.java

import android.app.job.JobParameters;
import android.app.job.JobService;
import android.widget.Toast;
 
  /**
   * JobService to be scheduled by the JobScheduler.
   * start another service
   */ 
public class TestJobService extends JobService {
@Override
public boolean onStartJob(JobParameters params) {
    Util.schedulerJob(getApplicationContext()); // reschedule the job
    Toast.makeText(this, "Bg Service", Toast.LENGTH_SHORT).show();
    return true;
}

@Override
public boolean onStopJob(JobParameters params) {
    return true;
  }
 }

After that BroadCast Receiver class named ServiceReceiver.java

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

 public class ServiceReceiver extends BroadcastReceiver {
 @Override
public void onReceive(Context context, Intent intent) {
    Util.schedulerJob(context);
 }
}

Update Manifest file with service and receiver class code

<receiver android:name=".ServiceReceiver" >
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
        </intent-filter>
    </receiver>
    <service
        android:name=".TestJobService"
        android:label="Word service"
        android:permission="android.permission.BIND_JOB_SERVICE" >

    </service>

Left main_intent launcher to mainActivity.java file which is created by default, and changes in MainActivity.java file are

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Util.schedulerJob(getApplicationContext());
  }
 }

WOOAAH!! Background Service starts without Foreground service

[Edit]: You can use Work Manager for any type of background tasks in Android.

You can use the lastval() function:

Return value most recently obtained with nextval for any sequence

So something like this:

INSERT INTO Table1 (name) VALUES ('a_title');
INSERT INTO Table2 (val)  VALUES (lastval());

This will work fine as long as no one calls nextval() on any other sequence (in the current session) between your INSERTs.

As Denis noted below and I warned about above, using lastval() can get you into trouble if another sequence is accessed using nextval() between your INSERTs. This could happen if there was an INSERT trigger on Table1 that manually called nextval() on a sequence or, more likely, did an INSERT on a table with a SERIAL or BIGSERIAL primary key. If you want to be really paranoid (a good thing, they really are you to get you after all), then you could use currval() but you'd need to know the name of the relevant sequence:

INSERT INTO Table1 (name) VALUES ('a_title');
INSERT INTO Table2 (val)  VALUES (currval('Table1_id_seq'::regclass));

The automatically generated sequence is usually named t_c_seq where t is the table name and c is the column name but you can always find out by going into psql and saying:

=> \d table_name;

and then looking at the default value for the column in question, for example:

id | integer | not null default nextval('people_id_seq'::regclass)

FYI: lastval() is, more or less, the PostgreSQL version of MySQL's LAST_INSERT_ID. I only mention this because a lot of people are more familiar with MySQL than PostgreSQL so linking lastval() to something familiar might clarify things.

A filter converting any dates in various ISO-related formats (and who'd use anything else after reading the writings of the Mighty Kuhn?) on standard input to seconds-since-the-epoch time on standard output might serve to illustrate both parts:

martind@whitewater:~$ cat `which isoToEpoch`
#!/usr/bin/perl -w
use strict;
use Time::Piece;
# sudo apt-get install libtime-piece-perl
while (<>) {
  # date --iso=s:
  # 2007-02-15T18:25:42-0800
  # Other matched formats:
  # 2007-02-15 13:50:29 (UTC-0800)
  # 2007-02-15 13:50:29 (UTC-08:00)
  s/(\d{4}-\d{2}-\d{2}([T ])\d{2}:\d{2}:\d{2})(?:\.\d+)? ?(?:\(UTC)?([+\-]\d{2})?:?00\)?/Time::Piece->strptime ($1, "%Y-%m-%d$2%H:%M:%S")->epoch - (defined ($3) ? $3 * 3600 : 0)/eg;
  print;
}
martind@whitewater:~$ 

Constructors don't return a type , just remove the return type which is void in your case. It would run fine then.

Just bind a trigger with the selector and put the code into the trigger event:

jQuery(function() {
  jQuery("#contentDiv:hidden").show().trigger('show');

  jQuery('#contentDiv').on('show', function() {
    console.log('#contentDiv is now visible');
    // your code here
  });
});

In my case I had to start a list of exclude extensions from the second line because xcopy ignored the first line.

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

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

Sourcetree: resetting remote to a certain commit

1. If you have pushed a bad commit to your remote (origin/feature/1337_MyAwesomeFeature) like below picture

2. Go to Remotes > origin > feature > 1337_MyAwesomeFeature
3. Right click and choose "Delete origin/feature/1337_MyAwesomeFeature" (Or change name of it if you want a backup and skip step 4.)
4. Click "Force delete" and "OK".

5. Select your older commit and choose "Reset current branch to this commit"
6. Choose which mode you want to have (Hard if you don't want your last changes) and "OK".

7. Push this commit to a new origin/feature/1337_MyAwesomeFeature

8. Your local feature branch and your remote feature branch are now on the previous (of your choice) commit

It took a while to put together a solution for this, but have found this is the easiest way to get it to work in the way that you describe. There could be better ways to do this, but since you haven't posted your activity code I will have to improvise and assume you have a list like this at the start of your activity:

private List<String> items = db.getItems();

ExampleActivity.java

private List<String> items;

private Menu menu;

@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {

    getMenuInflater().inflate(R.menu.example, menu);

    this.menu = menu;

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));

        search.setOnQueryTextListener(new OnQueryTextListener() { 

            @Override 
            public boolean onQueryTextChange(String query) {

                loadHistory(query);

                return true; 

            } 

        });

    }

    return true;

}

// History
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {

        // Cursor
        String[] columns = new String[] { "_id", "text" };
        Object[] temp = new Object[] { 0, "default" };

        MatrixCursor cursor = new MatrixCursor(columns);

        for(int i = 0; i < items.size(); i++) {

            temp[0] = i;
            temp[1] = items.get(i);

            cursor.addRow(temp);

        }

        // SearchView
        SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);

        final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();

        search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));

    }

}

Now you need to create an adapter extended from CursorAdapter:

ExampleAdapter.java

public class ExampleAdapter extends CursorAdapter {

    private List<String> items;

    private TextView text;

    public ExampleAdapter(Context context, Cursor cursor, List<String> items) {

        super(context, cursor, false);

        this.items = items;

    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {

        text.setText(items.get(cursor.getPosition()));

    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {

        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View view = inflater.inflate(R.layout.item, parent, false);

        text = (TextView) view.findViewById(R.id.text);

        return view;

    }

}

A better way to do this is if your list data is from a database, you can pass the Cursor returned by database functions directly to ExampleAdapter and use the relevant column selector to display the column text in the TextView referenced in the adapter.

Please note: when you import CursorAdapter don't import the Android support version, import the standard android.widget.CursorAdapter instead.

The adapter will also require a custom layout:

res/layout/item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView
        android:id="@+id/item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</RelativeLayout>

You can now customize list items by adding additional text or image views to the layout and populating them with data in the adapter.

This should be all, but if you haven't done this already you need a SearchView menu item:

res/menu/example.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/search"
        android:title="@string/search"
        android:showAsAction="ifRoom"
        android:actionViewClass="android.widget.SearchView" />

</menu>

Then create a searchable configuration:

res/xml/searchable.xml

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/search"
    android:hint="@string/search" >
</searchable>

Finally add this inside the relevant activity tag in the manifest file:

AndroidManifest.xml

<intent-filter>
    <action android:name="android.intent.action.SEARCH" />
</intent-filter>

<meta-data
    android:name="android.app.default_searchable"
    android:value="com.example.ExampleActivity" />
<meta-data

You can find first substring with this function in your code (by character index). Also, you can find what is after a substring.

def FindSubString(strText, strSubString, Offset=None):
    try:
        Start = strText.find(strSubString)
        if Start == -1:
            return -1 # Not Found
        else:
            if Offset == None:
                Result = strText[Start+len(strSubString):]
            elif Offset == 0:
                return Start
            else:
                AfterSubString = Start+len(strSubString)
                Result = strText[AfterSubString:AfterSubString + int(Offset)]
            return Result
    except:
        return -1

# Example:

Text = "Thanks for contributing an answer to Stack Overflow!"
subText = "to"

print("Start of first substring in a text:")
start = FindSubString(Text, subText, 0)
print(start); print("")

print("Exact substring in a text:")
print(Text[start:start+len(subText)]); print("")

print("What is after substring \"%s\"?" %(subText))
print(FindSubString(Text, subText))

# Your answer:

Text = "gfgfdAAA1234ZZZuijjk"
subText1 = "AAA"
subText2 = "ZZZ"

AfterText1 = FindSubString(Text, subText1, 0) + len(subText1)
BeforText2 = FindSubString(Text, subText2, 0) 

print("\nYour answer:\n%s" %(Text[AfterText1:BeforText2]))

The solution @doreamon provided works fine for all the cases except one:

If After login, Killing Login screen user navigated direct to a middle screen. e.g. In a flow of A->B->C, navigate like : Login -> B -> C -> Press shortcut to home. Using FLAG_ACTIVITY_CLEAR_TOP clears only C activity, As the Home(A) is not on stack history. Pressing Back on A screen will lead us back to B.

To tackle this problem, We can keep an activity stack(Arraylist) and when home is pressed, we have to kill all the activities in this stack.

The warning message MAY BE due to an XMLHttpRequest request within the main thread with the async flag set to false.

https://xhr.spec.whatwg.org/#synchronous-flag:

Synchronous XMLHttpRequest outside of workers is in the process of being removed from the web platform as it has detrimental effects to the end user's experience. (This is a long process that takes many years.) Developers must not pass false for the async argument when the JavaScript global environment is a document environment. User agents are strongly encouraged to warn about such usage in developer tools and may experiment with throwing an InvalidAccessError exception when it occurs.

The future direction is to only allow XMLHttpRequests in worker threads. The message is intended to be a warning to that effect.

Apple's recommendation recoded in Swift + Using UIScrollView with Auto Layout in iOS (basing on these following links: link 1, link 2, link 3):

I did two things inspired by @OscarJovanny comment, with some hacks.

Step 1:

• Download icons file as svg from Here, as I only need only this icon from font awesome

Step 2:

<style>
ul {
    list-style-type: none;
    margin-left: 10px;
}

ul li {
    margin-bottom: 12px;
    margin-left: -10px;
    display: flex;
    align-items: center;
}

ul li::before {
    color: transparent;
    font-size: 1px;
    content: " ";
    margin-left: -1.3em;
    margin-right: 15px;
    padding: 10px;
    background-color: orange;
    -webkit-mask-image: url("./assets/img/check-circle-solid.svg");
    -webkit-mask-size: cover;
}
</style>

Results

$dateTime = new DateTime('now', new DateTimeZone('Asia/Kolkata')); 
echo $dateTime->modify("+10 minutes")->format("H:i:s A");

I got the same error as I didn't save the script before executing it. Check to see if you have saved it!

For me this works

 
if($("#myModal").css("display") !='none' && $("#myModal").css("visibility") != 'hidden')

alert("modal shown");

I originally found a CSS way to bypass this when using the Cycle jQuery plugin. Cycle uses JavaScript to set my slide to overflow: hidden, so when setting my pictures to width: 100% the pictures would look vertically cut, and so I forced them to be visible with !important and to avoid showing the slide animation out of the box I set overflow: hidden to the container div of the slide. Hope it works for you.

UPDATE - New Solution:

Original problem -> http://jsfiddle.net/xMddf/1/ (Even if I use overflow-y: visible it becomes "auto" and actually "scroll".)

#content {
    height: 100px;
    width: 200px;
    overflow-x: hidden;
    overflow-y: visible;
}

The new solution -> http://jsfiddle.net/xMddf/2/ (I found a workaround using a wrapper div to apply overflow-x and overflow-y to different DOM elements as James Khoury advised on the problem of combining visible and hidden to a single DOM element.)

#wrapper {
    height: 100px;
    overflow-y: visible;
}
#content {
    width: 200px;
    overflow-x: hidden;
}

From Java 8 onward you can try the following:

import java.time.*;
import java.time.temporal.ChronoUnit;

Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();

System.out.println(Duration.between(start_time, stop_time).toMillis());

//or

System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));

Try this:

$str = "Hello Friend";

$arr1 = str_split($str);
$arr2 = str_split($str, 3);

print_r($arr1);
print_r($arr2);

The above example will output:

Array
(
    [0] => H
    [1] => e
    [2] => l
    [3] => l
    [4] => o
    [5] =>
    [6] => F
    [7] => r
    [8] => i
    [9] => e
    [10] => n
    [11] => d
)

Array
(
    [0] => Hel
    [1] => lo
    [2] => Fri
    [3] => end
)

I FINALLY fixed this, I had forgotten to add the following code to my .m file:

@implementation MyTableViewCell

@end

So it was being caused because I had made a placeholder @interface for my table cell, that had a connection to an element in the .xib file, but there is a bug in Interface Builder where if no @implementation is specified for a class, it can't find it.

I had gone through all of the steps from other forums of viewing the .xib as source and seeing MyTableViewCell even though I had commented it out of my code. I had tried resetting the simulator. I even tried breaking all of my classes up into separate files named the same as the interfaces, but nothing worked until this.

P.S. in my experience, it doesn't matter if the names of the .h/.m files are different from the names of the @interface. I have several files containing more than one @interface and they work fine.

P.P.S. I have a more detailed explanation of why UITableViewCell and UICollectionViewCell cause this error at https://stackoverflow.com/a/22797318/539149 along with how to reveal it at compile-time using registerClass: forCellWithReuseIdentifier:.

I was having trouble with mobile touchscreen button styling. This will fix your hover-stick / active button problems.

body, html {
  width: 600px;
}
p {
  font-size: 20px;
}

button {
  border: none;
  width: 200px;
  height: 60px;
  border-radius: 30px;
  background: #00aeff;
  font-size: 20px;
}

button:active {
  background: black;
  color: white;
}

.delayed {
  transition: all 0.2s;
  transition-delay: 300ms;
}

.delayed:active {
  transition: none;
}

<h1>Sticky styles for better touch screen buttons!</h1>

<button>Normal button</button>

<button class="delayed"><a href="https://www.google.com"/>Delayed style</a></button>

<p>The CSS :active psuedo style is displayed between the time when a user touches down (when finger contacts screen) on a element to the time when the touch up (when finger leaves the screen) occures.   With a typical touch-screen tap interaction, the time of which the :active psuedo style is displayed can be very small resulting in the :active state not showing or being missed by the user entirely.  This can cause issues with users not undertanding if their button presses have actually reigstered or not.</p>

<p>Having the the :active styling stick around for a few hundred more milliseconds after touch up would would improve user understanding when they have interacted with a button.</p>

from @Przemek 's answer,

function listenClickOnly(element, callback, threshold=10) {
  let drag = 0;
  element.addEventListener('mousedown', () => drag = 0);
  element.addEventListener('mousemove', () => drag++);
  element.addEventListener('mouseup', e => {
    if (drag<threshold) callback(e);
  });
}

listenClickOnly(
  document,
  () => console.log('click'),
  10
);

This code works for me: check this link
This is my code when i stop and start service in activity

case R.id.buttonStart:
  Log.d(TAG, "onClick: starting srvice");
  startService(new Intent(this, MyService.class));
  break;
case R.id.buttonStop:
  Log.d(TAG, "onClick: stopping srvice");
  stopService(new Intent(this, MyService.class));
  break;
}
}
 }

And in service class:

  @Override
public void onCreate() {
    Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onCreate");

    player = MediaPlayer.create(this, R.raw.braincandy);
    player.setLooping(false); // Set looping
}

@Override
public void onDestroy() {
    Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
    Log.d(TAG, "onDestroy");
    player.stop();
}

HAPPY CODING!

I don't see why there is a encapsulation of a while...

Use

//Use the appropriate start and end...
for(int rowIndex = 0, e = 65536; i < e; ++i){        
    if(rowIndex >= dataColLinker.size()) {
         dataColLinker.add(value);
     } else {
        dataColLinker.set(rowIndex, value);

If you are using eclipse IDE then :

• Select Project.

• Press alt+F5, window for Update Maven Project will pop up.

• Check - Force Update of Snapshots/releases and click OK.

If Using Intellij IDE

• go to settings/Maven
• check Always update snapshots

I've created a small plugin (available on NuGet) that allows you to add any (if supported by your terminal) color to your console output, without the limitations of the classic solutions.

It works by extending the String object and the syntax is very simple:

"colorize me".Pastel("#1E90FF");

Both foreground and background colors are supported.

Try this:

int index = row.Table.Columns["ColumnName"].Ordinal;

According to https://forums.oracle.com/forums/thread.jspa?messageID=6594485&#6594485 Random.nextInt(n) is both more efficient and less biased than Math.random() * n

to also check blank string, I suggest following

<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>

<c:if test="${empty fn:trim(var1)}">

</c:if>

It also handles nulls

Test e = static_cast<Test>(1);

Call this function when ready to validate what ever. I used a textbox here

In my HTML:

<input type="button" value="Check IT!" onclick="check(document.getElementById('inputboxToValidate').value);" />

In my JavaScript code:

function check(num){
    var onlynumbers = true
    for (var i = 0; i < (num.length - 1); i++) {
        if (num.substr(i, 1) != "0" || num.substr(i, 1) != "1" || num.substr(i, 1) != "2" || num.substr(i, 1) != "3" || num.substr(i, 1) != "4" || num.substr(i, 1) != "5" || num.substr(i, 1) != "6" || num.substr(i, 1) != "7" || num.substr(i, 1) != "8" || num.substr(i, 1) != "9") {
            alert("please make sure that only numbers have been entered in the Quantaty box");
            onlynumbers = false
        }
    }
    if (onlynumbers == true) {

        //Execute Code
    }
}

Surprised that I did not see the below query selector way solution,

document.querySelector('#xyz').style.paddingTop = "10px"

CSSStyleDeclaration solutions, an example of the accepted answer

document.getElementById('xyz').style.paddingTop = "10px";

Try

if( this["person_data[document_type]"].value != '') { _x000D_
  console.log('not empty');_x000D_
}

<input id="person_data[document_type]" value="test" />

If you're using webservices, you'll also need the 'allow-http-request-headers-from' element. Here's our default, development, 'allow everything' policy.

<?xml version="1.0" ?>
<cross-domain-policy>
  <site-control permitted-cross-domain-policies="master-only"/>
  <allow-access-from domain="*"/>
  <allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>

Inspired by the insightful answers on this page, I created a mixed approach, which I consider the simplest and more flexible one. What do you think?

First, I define the usage in a variable, which allows me to reuse it in different contexts. The format is very simple, almost WYSIWYG, without the need to add any control characters. This seems reasonably portable to me (I ran it on MacOS and Ubuntu)

__usage="
Usage: $(basename $0) [OPTIONS]

Options:
  -l, --level <n>              Something something something level
  -n, --nnnnn <levels>         Something something something n
  -h, --help                   Something something something help
  -v, --version                Something something something version
"

Then I can simply use it as

echo "$__usage"

or even better, when parsing parameters, I can just echo it there in a one-liner:

levelN=${2:?"--level: n is required!""${__usage}"}

Until I was really concerned about performance, I would use a function, that takes a base and returns its match:

char base_pair(char base)
{
    switch(base) {
        case 'T': return 'A';
        ... etc
        default: // handle error
    }
}

If I was concerned about performance, I would define a base as one fourth of a byte. 0 would represent A, 1 would represent G, 2 would represent C, and 3 would represent T. Then I would pack 4 bases into a byte, and to get their pairs, I would simply take the complement.

break or goto

while ( true ) {
  if ( conditional ) {
    break;
  }
  if ( other conditional ) {
    goto EndWhile;
  }
}
EndWhile:

Your problem seems unclear. You say you want to remove "a character from a certain position" then go on to say you want to remove a particular character.

If you only need to remove the first character you would do:

s = ":dfa:sif:e"
fixed = s[1:]

If you want to remove a character at a particular position, you would do:

s = ":dfa:sif:e"
fixed = s[0:pos]+s[pos+1:]

If you need to remove a particular character, say ':', the first time it is encountered in a string then you would do:

s = ":dfa:sif:e"
fixed = ''.join(s.split(':', 1))

1. A static method can NOT access a Non-static method or variable.

2. public static void main(String[] args) is a static method, so can NOT access the Non-static public static int fxn(int y) method.

3. Try it this way...

   static int fxn(int y)

   public class Two {
   
   
       public static void main(String[] args) {
           int x = 0;
   
           System.out.println("x = " + x);
           x = fxn(x);
           System.out.println("x = " + x);
       }
   
       static int fxn(int y) {
           y = 5;
           return y;
       }
   

   }

I had a similar problem with a physical device. The problem was related with the fact that the google app ( the search bar for google on top ) was disabled. After the first reboot launcher3 began failing. No matter how many cache/data cleaning I did, it kept failing. I reenabled it and launched it, so it appeared again on the screen and from that moment on, launcher3 was back to life.

I guess there mmust be some kind of dependency with this app.

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

It seems like there is permission on mobile keypad setting, so the easiest way to do this is:

editText.setFilters(new InputFilter[]{new InputFilter.AllCaps()});

hope this will work

Converting your set into an array may also help you for iterating over the elements:

Object[] array = set.toArray();

for(int i=0; i<array.length; i++)
   Object o = array[i];

I'm not sure there is point in such conversion (yes, many do it, but mostly to force a square peg through round hole) -- there is structural impedance mismatch, and conversion is lossy. So I would recommend against such format-to-format transformations.

But if you do it, first convert from json to object, then from object to xml (and vice versa for reverse direction). Doing direct transformation leads to ugly output, loss of information, or possibly both.

I'm doing something similar, but in my case I'm doing serialization/De-serialization so I need to be able to go both directions. I find using a string[][] works nearly identically to the dictionary, including initialization, but you can go the other direction too, returning the substitutes to their original values, something that the dictionary really isn't set up to do.

Edit: You can use Dictionary<Key,List<Values>> in order to obtain same result as string[][]

Use Convert.ToDouble(value) rather than (double)value. It takes an object and supports all of the types you asked for! :)

Also, your method is always returning a string in the code above; I'd recommend having the method indicate so, and give it a more obvious name (public string FormatLargeNumber(object value))

In addition to other answers, comments and documentation, the datatype cast can be placed on usage. This allows an easier copypasting:

update test as t set
    column_a = c.column_a::number
from (values
    ('123', 1),
    ('345', 2)  
) as c(column_b, column_a) 
where t.column_b = c.column_b::text;

Although qTip (the accepted answer) is good, I started using it, and it lacked some features I needed.

I then stumbled upon PoshyTip - it is very flexible, and really easy to use. (And I could do what I needed)

If you have many fields in select statement and you want latest value for all of those fields through optimized code:

select * from
(select * from table_name
order by id,rev desc) temp
group by id 

Yes, you may put comments in there. They however must start at the beginning of a line.

cf. http://git-scm.com/book/en/Git-Basics-Recording-Changes-to-the-Repository#Ignoring-Files

The rules for the patterns you can put in the .gitignore file are as follows:
- Blank lines or lines starting with # are ignored.
[…]

The comment character is #, example:

# no .a files
*.a

When you just give make, it makes the first rule in your makefile, i.e "all". You have specified that "all" depends on "hello", which depends on main.o, factorial.o and hello.o. So 'make' tries to see if those files are present.

If they are present, 'make' sees if their dependencies, e.g. main.o has a dependency main.c, have changed. If they have changed, make rebuilds them, else skips the rule. Similarly it recursively goes on building the files that have changed and finally runs the top most command, "all" in your case to give you a executable, 'hello' in your case.

If they are not present, make blindly builds everything under the rule.

Coming to your problem, it isn't an error but 'make' is saying that every dependency in your makefile is up to date and it doesn't need to make anything!

Try:

UPDATE table1
SET CalculatedColumn = ( SELECT [Calculated Column] 
                         FROM table2 
                         WHERE table1.commonfield = [common field])
WHERE  BatchNO = '110'

"every link that specifies target="_new" looks for and finds that window by name, and opens in it.

If you use target="_blank," a brand new window will be created each time, on top of the current window."

Here's a Boolean thing:

if (not suffix == "flac" )  or (not suffix == "cue" ):   # WRONG! FAILS
    print  filename + ' is not a flac or cue file'

but

if not (suffix == "flac"  or suffix == "cue" ):     # CORRECT!
       print  filename + ' is not a flac or cue file'

(not a) or (not b) == not ( a and b ) , is false only if a and b are both true

not (a or b) is true only if a and be are both false.

In Firefox there is Ctrl+Shift+K for the Web console, then you type

;decodeURIComponent("%2c")

• mind the semicolon in the beginning
• if you Copy&Paste, you should first enable it (the console will warn you)

and you get the answer:

","

[This is a late answer addressing the title of the question (since that is what people would encounter when searching) rather than the specifics of OP's question which has already been answered adequately]

Ubound is a bit fragile in that it provides no way to know how many dimensions an array has. You can use error trapping to determine the full layout of an array. The following returns a collection of arrays, one for each dimension. The count property can be used to determine the number of dimensions and their lower and upper bounds can be extracted as needed:

Function Bounds(A As Variant) As Collection
    Dim C As New Collection
    Dim v As Variant, i As Long

    On Error GoTo exit_function
    i = 1
    Do While True
        v = Array(LBound(A, i), UBound(A, i))
        C.Add v
        i = i + 1
    Loop
exit_function:
    Set Bounds = C
End Function

Used like this:

Sub test()
    Dim i As Long
    Dim A(1 To 10, 1 To 5, 4 To 10) As Integer
    Dim B(1 To 5) As Variant
    Dim C As Variant
    Dim sizes As Collection

    Set sizes = Bounds(A)
    Debug.Print "A has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i

    Set sizes = Bounds(B)
    Debug.Print vbCrLf & "B has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i

    Set sizes = Bounds(C)
    Debug.Print vbCrLf & "C has " & sizes.Count & " dimensions:"
    For i = 1 To sizes.Count
        Debug.Print sizes(i)(0) & " to " & sizes(i)(1)
    Next i
End Sub

Output:

A has 3 dimensions:
1 to 10
1 to 5
4 to 10

B has 1 dimensions:
1 to 5

C has 0 dimensions:

Review the file on github and pull it from there

This is a pragmatic approach which doesn't directly answer the OP, but some have found useful:

If the branch in question is on GitHub, then you can navigate to the desired branch and file using any of the many tools that GitHub offers, then click 'Raw' to view the plain text, and (optionally) copy and paste the text as desired.

I like this approach because it lets you look at the remote file in its entirety before pulling it to your local machine.

When working with Swift, you can use the enum UIUserInterfaceIdiom, defined as:

enum UIUserInterfaceIdiom : Int {
    case unspecified
    
    case phone // iPhone and iPod touch style UI
    case pad   // iPad style UI (also includes macOS Catalyst)
}

So you can use it as:

UIDevice.current.userInterfaceIdiom == .pad
UIDevice.current.userInterfaceIdiom == .phone
UIDevice.current.userInterfaceIdiom == .unspecified

Or with a Switch statement:

    switch UIDevice.current.userInterfaceIdiom {
    case .phone:
        // It's an iPhone
    case .pad:
        // It's an iPad (or macOS Catalyst)

     @unknown default:
        // Uh, oh! What could it be?
    }

UI_USER_INTERFACE_IDIOM() is an Objective-C macro, which is defined as:

#define UI_USER_INTERFACE_IDIOM() \ ([[UIDevice currentDevice] respondsToSelector:@selector(userInterfaceIdiom)] ? \ [[UIDevice currentDevice] userInterfaceIdiom] : \ UIUserInterfaceIdiomPhone)

Also, note that even when working with Objective-C, the UI_USER_INTERFACE_IDIOM() macro is only required when targeting iOS 3.2 and below. When deploying to iOS 3.2 and up, you can use [UIDevice userInterfaceIdiom] directly.

Simply using an outer directory for the output, solved the problem for me.

Not being able to reply to/endorse this answer, so posting here:

Indeed, the format of the source/destination ranges when moving data from one range to another might cause this error as well.

In my case, the range I wanted to copy contained a date formatted column, and the column contained one cell with an invalid date value (it was not even formatted due to its value, which was a negative integer). So the copy operation between the two ranges was halting at the said cell yielding the very error message discussed here.

The solution in my case was to use Range.Value2 instead of Range.Value, which caused Excel to bypass formatting the cell as a date (more details here). However, this will render your date and time columns to display as integers and decimals. You will, however, be able to change the formats to the desired ones if you know where to expect the date and time values by setting their Range/Column/Cell.NumberFormat property accordingly.

UseParNewGC usually knowns as "parallel young generation collector" is same in all ways as the parallel garbage collector (-XX:+UseParallelGC), except that its more sophiscated and effiecient. Also it can be used with a "concurrent low pause collector".

See Java GC FAQ, question 22 for more information.

Note that there are some known bugs with UseParNewGC

If your strings are compile time constants (as in your case) you can use the following trick:

#define USER_JACK strcmp(USER, "jack")
#define USER_QUEEN strcmp(USER, "queen")
#if $USER_JACK == 0
#define USER_VS USER_QUEEN
#elif USER_QUEEN == 0
#define USER_VS USER_JACK
#endif

The compiler can tell the result of the strcmp in advance and will replace the strcmp with its result, thus giving you a #define that can be compared with preprocessor directives. I don't know if there's any variance between compilers/dependance on compiler options, but it worked for me on GCC 4.7.2.

EDIT: upon further investigation, it look like this is a toolchain extension, not GCC extension, so take that into consideration...

Although it's not really clear to me what you're trying to achieve, I spotted an obvious error in your code: Field.get() expects the object which contains the field as argument, not some (possible) value of that field. So you should have field.get(object).

Since you appear to be looking for the field value, you can obtain that as:

Object objectValue = field.get(object);

No need to instantiate the field type and create some empty/default value; or maybe there's something I missed.

If you still want to show the item but make it not clickable and look disabled with CSS:

CSS:

.disabled {
    pointer-events:none; //This makes it not clickable
    opacity:0.6;         //This grays it out to look disabled
}

HTML:

<li class="disabled">Disabled List Item</li>

Also, if you are using BootStrap, they already have a class called disabled for this purpose. See this example.

As @LV98 pointed out, users could change this on the client side and submit a selection you weren't expecting. You will want to validate at the server as well.

Short answer : theoretically YES, but this has to be a VERY GOOD friend of yours, but again, you might prefer to buy a used mac-mini

TLDR : You will need this Mac for a really long time, depending on your app requirements, your development skills, and your luck with Apple. For example:

1. You might need some days to set up Xcode and the required SDKs and Libraries.
2. It might take some time to get that Developer Account, sometimes you can wait too much even to get your request reviewed.
3. When you submit your application for the first time, you will have to wait sometime, maybe up to several weeks, or even months, to get your app reviewed.
4. Each time your app gets rejected, you will need to find and fix your issues (without much help from Apple, other that pointing out the guideline rule that you broke ), then re-submit your app for review, and wait again.
5. Each time you try to apply a patch for your already deployed app, you will have to get your app reviewed and there is a chance that your previously legit app, now breaks a new guideline, so you re-submit and wait

So, from my experience the development of an iOS app is a very lengthy procedure, without even considering the actual code-development time. Can you borrow a Mac for that long ?

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

This command will show also if the file is hidden adb shell ls -laR | grep filename

You can have a look at this link for a comparison of the two (and others) approaches in a real example.

Basically, when requirements change, you end up modifying more code if you use factories instead of DI.

This is also valid with manual DI (i.e. when there isn't an external framework that provides the dependencies to your objects, but you pass them in each constructor).

Perhaps your main function has been commented out because of e.g. preprocessing. To learn what preprocessing is doing, try gcc -C -E es3.c > es3.i then look with an editor into the generated file es3.i (and search main inside it).

First, you should always (since you are a newbie) compile with

  gcc -Wall -g -c es3.c
  gcc -Wall -g es3.o -o es3

The -Wall flag is extremely important, and you should always use it. It tells the compiler to give you (almost) all warnings. And you should always listen to the warnings, i.e. correct your source code file es3.C till you got no more warnings.

The -g flag is important also, because it asks gcc to put debugging information in the object file and the executable. Then you are able to use a debugger (like gdb) to debug your program.

To get the list of symbols in an object file or an executable, you can use nm.

Of course, I'm assuming you use a GNU/Linux system (and I invite you to use GNU/Linux if you don't use it already).

if you want to access a method :

1) while using an object of a class:

Myclass myclass;
myclass.DoSomething();

2) while using a pointer to an object of a class:

Myclass *myclass=&abc;
myclass->DoSomething();

For example you can find any textView:

TextView textView = (TextView) ((Activity) context).findViewById(R.id.textView1);

Where ever you need to text in one line put this code

white-space:nowrap

As mentioned, there are crawler frameworks all ready for customizing out there, but if what you're doing is as simple as you mentioned, you could make it from scratch pretty easily.

To find menu items in content page base on roles

 protected void Page_Load(object sender, EventArgs e)
{
   if (Session["AdminSuccess"] != null)
        {
           Menu mainMenu = (Menu)Page.Master.FindControl("NavigationMenu");

    //you must know the index of items to be removed first
    mainMenu.Items.RemoveAt(1);

    //or you try to hide menu and list items inside menu with css 
    // cssclass must be defined in style tag in .aspx page
    mainMenu.CssClass = ".hide";

Using Set Function eg:-

arr=[1,4,2,5,2,3,4,1,4,5,2,3]
arr2=list(set(arr))
print(arr2)

Output:- [1, 2, 3, 4, 5]

2. Remove Duplicates using array

eg:-

arr=[1,4,2,5,2,3,4,1,4,5,2,3]
arr3=[]
for i in arr:
    if(i not in arr3):
     arr3.append(i)
print(arr3)

Output:-

[1, 4, 2, 5, 3]

3. Using Lambda Function

eg:-

rem_duplicate_func=lambda arr:set(arr)
print(rem_duplicate_func(arr))

Output:-

{1, 2, 3, 4, 5}

4. Remove Duplicate Values from dictionary

eg:-

dict1={
    'car':["Ford","Toyota","Ford","Toyota"],
    'brand':["Mustang","Ranz","Mustang","Ranz"] } dict2={} for key,value in dict1.items():
    dict2[key]=set(value) print(dict2)

Output:-

{'car': {'Toyota', 'Ford'}, 'brand': {'Ranz', 'Mustang'}}

5. Symmetric difference- Remove duplicate elements

eg:-

set1={1,2,4,5}
set2={2,1,5,7}
rem_dup_ele=set1.symmetric_difference(set2)
print(rem_dup_ele)

Output:-

{4, 7}

How to auto increment by one, starting at 10 in MySQL:

create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;

'10', 'abc'
'11', 'def'
'12', 'xyz'

This auto increments the id column by one starting at 10.

Auto increment in MySQL by 5, starting at 10:

drop table foobar
create table foobar(
  id             INT PRIMARY KEY AUTO_INCREMENT,
  moobar         VARCHAR(500)
); 
SET @@auto_increment_increment=5;
ALTER TABLE foobar AUTO_INCREMENT=10;

INSERT INTO foobar(moobar) values ("abc");
INSERT INTO foobar(moobar) values ("def");
INSERT INTO foobar(moobar) values ("xyz");

select * from foobar;
'11', 'abc'
'16', 'def'
'21', 'xyz'

This auto increments the id column by 5 each time, starting at 10.

Have you taken a look at ExpandoObject?

see: http://blogs.msdn.com/b/csharpfaq/archive/2009/10/01/dynamic-in-c-4-0-introducing-the-expandoobject.aspx

From MSDN:

The ExpandoObject class enables you to add and delete members of its instances at run time and also to set and get values of these members. This class supports dynamic binding, which enables you to use standard syntax like sampleObject.sampleMember instead of more complex syntax like sampleObject.GetAttribute("sampleMember").

Allowing you to do cool things like:

dynamic dynObject = new ExpandoObject();
dynObject.SomeDynamicProperty = "Hello!";
dynObject.SomeDynamicAction = (msg) =>
    {
        Console.WriteLine(msg);
    };

dynObject.SomeDynamicAction(dynObject.SomeDynamicProperty);

Based on your actual code you may be more interested in:

public static dynamic GetDynamicObject(Dictionary<string, object> properties)
{
    return new MyDynObject(properties);
}

public sealed class MyDynObject : DynamicObject
{
    private readonly Dictionary<string, object> _properties;

    public MyDynObject(Dictionary<string, object> properties)
    {
        _properties = properties;
    }

    public override IEnumerable<string> GetDynamicMemberNames()
    {
        return _properties.Keys;
    }

    public override bool TryGetMember(GetMemberBinder binder, out object result)
    {
        if (_properties.ContainsKey(binder.Name))
        {
            result = _properties[binder.Name];
            return true;
        }
        else
        {
            result = null;
            return false;
        }
    }

    public override bool TrySetMember(SetMemberBinder binder, object value)
    {
        if (_properties.ContainsKey(binder.Name))
        {
            _properties[binder.Name] = value;
            return true;
        }
        else
        {
            return false;
        }
    }
}

That way you just need:

var dyn = GetDynamicObject(new Dictionary<string, object>()
    {
        {"prop1", 12},
    });

Console.WriteLine(dyn.prop1);
dyn.prop1 = 150;

Deriving from DynamicObject allows you to come up with your own strategy for handling these dynamic member requests, beware there be monsters here: the compiler will not be able to verify a lot of your dynamic calls and you won't get intellisense, so just keep that in mind.

one simple way SELECT '123'+ 0

A VIP swap is an internal change to Azure's routers/load balancers, not an external DNS change. They're just routing traffic to go from one internal [set of] server[s] to another instead. Therefore the DNS info for mysite.cloudapp.net doesn't change at all. Therefore the change for people accessing via the IP bound to mysite.cloudapp.net (and CNAME'd by you) will see the change as soon as the VIP swap is complete.

Public:

When you declare a method (function) or a property (variable) as public, those methods and properties can be accessed by:

• The same class that declared it.
• The classes that inherit the above declared class.
• Any foreign elements outside this class can also access those things.

Example:

<?php

class GrandPa
{
    public $name='Mark Henry';  // A public variable
}

class Daddy extends GrandPa // Inherited class
{
    function displayGrandPaName()
    {
        return $this->name; // The public variable will be available to the inherited class
    }

}

// Inherited class Daddy wants to know Grandpas Name
$daddy = new Daddy;
echo $daddy->displayGrandPaName(); // Prints 'Mark Henry'

// Public variables can also be accessed outside of the class!
$outsiderWantstoKnowGrandpasName = new GrandPa;
echo $outsiderWantstoKnowGrandpasName->name; // Prints 'Mark Henry'

Protected:

When you declare a method (function) or a property (variable) as protected, those methods and properties can be accessed by

• The same class that declared it.
• The classes that inherit the above declared class.

Outsider members cannot access those variables. "Outsiders" in the sense that they are not object instances of the declared class itself.

Example:

<?php

class GrandPa
{
    protected $name = 'Mark Henry';
}

class Daddy extends GrandPa
{
    function displayGrandPaName()
    {
        return $this->name;
    }

}

$daddy = new Daddy;
echo $daddy->displayGrandPaName(); // Prints 'Mark Henry'

$outsiderWantstoKnowGrandpasName = new GrandPa;
echo $outsiderWantstoKnowGrandpasName->name; // Results in a Fatal Error

The exact error will be this:

PHP Fatal error: Cannot access protected property GrandPa::$name

Private:

When you declare a method (function) or a property (variable) as private, those methods and properties can be accessed by:

• The same class that declared it.

Outsider members cannot access those variables. Outsiders in the sense that they are not object instances of the declared class itself and even the classes that inherit the declared class.

Example:

<?php

class GrandPa
{
    private $name = 'Mark Henry';
}

class Daddy extends GrandPa
{
    function displayGrandPaName()
    {
        return $this->name;
    }

}

$daddy = new Daddy;
echo $daddy->displayGrandPaName(); // Results in a Notice 

$outsiderWantstoKnowGrandpasName = new GrandPa;
echo $outsiderWantstoKnowGrandpasName->name; // Results in a Fatal Error

The exact error messages will be:

Notice: Undefined property: Daddy::$name
Fatal error: Cannot access private property GrandPa::$name

Dissecting the Grandpa Class using Reflection

This subject is not really out of scope, and I'm adding it here just to prove that reflection is really powerful. As I had stated in the above three examples, protected and private members (properties and methods) cannot be accessed outside of the class.

However, with reflection you can do the extra-ordinary by even accessing protected and private members outside of the class!

Well, what is reflection?

Reflection adds the ability to reverse-engineer classes, interfaces, functions, methods and extensions. Additionally, they offers ways to retrieve doc comments for functions, classes and methods.

Preamble

We have a class named Grandpas and say we have three properties. For easy understanding, consider there are three grandpas with names:

• Mark Henry
• John Clash
• Will Jones

Let us make them (assign modifiers) public, protected and private respectively. You know very well that protected and private members cannot be accessed outside the class. Now let's contradict the statement using reflection.

The code

<?php

class GrandPas   // The Grandfather's class
{
    public     $name1 = 'Mark Henry';  // This grandpa is mapped to a public modifier
    protected  $name2 = 'John Clash';  // This grandpa is mapped to a protected  modifier
    private    $name3 = 'Will Jones';  // This grandpa is mapped to a private modifier
}


# Scenario 1: without reflection
$granpaWithoutReflection = new GrandPas;

# Normal looping to print all the members of this class
echo "#Scenario 1: Without reflection<br>";
echo "Printing members the usual way.. (without reflection)<br>";
foreach($granpaWithoutReflection as $k=>$v)
{
    echo "The name of grandpa is $v and he resides in the variable $k<br>";
}

echo "<br>";

#Scenario 2: Using reflection

$granpa = new ReflectionClass('GrandPas'); // Pass the Grandpas class as the input for the Reflection class
$granpaNames=$granpa->getDefaultProperties(); // Gets all the properties of the Grandpas class (Even though it is a protected or private)


echo "#Scenario 2: With reflection<br>";
echo "Printing members the 'reflect' way..<br>";

foreach($granpaNames as $k=>$v)
{
    echo "The name of grandpa is $v and he resides in the variable $k<br>";
}

Output:

#Scenario 1: Without reflection
Printing members the usual way.. (Without reflection)
The name of grandpa is Mark Henry and he resides in the variable name1

#Scenario 2: With reflection
Printing members the 'reflect' way..
The name of grandpa is Mark Henry and he resides in the variable name1
The name of grandpa is John Clash and he resides in the variable name2
The name of grandpa is Will Jones and he resides in the variable name3

Common Misconceptions:

Please do not confuse with the below example. As you can still see, the private and protected members cannot be accessed outside of the class without using reflection

<?php

class GrandPas   // The Grandfather's class
{
    public     $name1 = 'Mark Henry';  // This grandpa is mapped to a public modifier
    protected  $name2 = 'John Clash';  // This grandpa is mapped to a protected modifier
    private    $name3 = 'Will Jones';  // This grandpa is mapped to a private modifier
}

$granpaWithoutReflections = new GrandPas;
print_r($granpaWithoutReflections);

Output:

GrandPas Object
(
    [name1] => Mark Henry
    [name2:protected] => John Clash
    [name3:GrandPas:private] => Will Jones
)

Debugging functions

print_r, var_export and var_dump are debugger functions. They present information about a variable in a human-readable form. These three functions will reveal the protected and private properties of objects with PHP 5. Static class members will not be shown.

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

}

Output:

Adding an approach to this old question just for the fun of it:

$ cat input.file # file containing input that needs to be processed
a;b;c;d;e
1;2;3;4;5
no delimiter here
124;adsf;15454
foo;bar;is;null;info

$ cat tmp.sh # showing off the script to do the job
#!/bin/bash
delim=';'
while read -r line; do  
    while [[ "$line" =~ "$delim" ]]; do
        line=$(cut -d"$delim" -f 2- <<<"$line")
    done
    echo "$line"
done < input.file

$ ./tmp.sh # output of above script/processed input file
e
5
no delimiter here
15454
info

Besides bash, only cut is used. Well, and echo, I guess.

Since git 2.23 (August 2019) you now have a shortcut to do that: git restore --staged [filepath]. With this command, you could ignore a conflicted file without needing to add and remove that.

Example:

> git status

  ...
  Unmerged paths:
    (use "git add <file>..." to mark resolution)
      both modified:   file.ex

> git restore --staged file.ex

> git status

  ...
  Changes not staged for commit:
    (use "git add <file>..." to update what will be committed)
    (use "git restore <file>..." to discard changes in working directory)
      modified:   file.ex

Try to use datepicker/ timepicker instead of datetimepicker like:

replace:

$('#datetimepicker1').datetimepicker();

with:

$('#datetimepicker1').datepicker(); // or timepicker for time picker

We can access super class elements by using super keyword

Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.

    class parent {
    String str="I am parent";
    //method of parent Class
    public void foo() {
        System.out.println("Hello World " + str);
    }
}

class child extends parent {
    String str="I am child";
    // different foo implementation in child Class
    public void foo() {
        System.out.println("Hello World "+str);
    }

    // calling the foo method of parent class
    public void parentClassFoo(){
        super.foo();
    }

    // changing the value of str in parent class and calling the foo method of parent class
    public void parentClassFooStr(){
        super.str="parent string changed";
        super.foo();
    }
}


public class Main{
        public static void main(String args[]) {
            child obj = new child();
            obj.foo();
            obj.parentClassFoo();
            obj.parentClassFooStr();
        }
    }

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

    View view = inflater.inflate(R.layout.writeqrcode_main, container, false);
    // Inflate the layout for this fragment

    txt_name = (TextView) view.findViewById(R.id.name);
    txt_usranme = (TextView) view.findViewById(R.id.surname);
    txt_number = (TextView) view.findViewById(R.id.number);
    txt_province = (TextView) view.findViewById(R.id.province);
    txt_write = (EditText) view.findViewById(R.id.editText_write);
    txt_show1 = (Button) view.findViewById(R.id.buttonShow1);

    txt_show1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.e("Onclick","Onclick");

            txt_show1.setVisibility(View.INVISIBLE);
            txt_name.setVisibility(View.VISIBLE);
            txt_usranme.setVisibility(View.VISIBLE);
            txt_number.setVisibility(View.VISIBLE);
            txt_province.setVisibility(View.VISIBLE);
        }
    });
    return view;
}

You OK !!!!

Few things to fix here:

1. No parenthesis in class declaration
2. Make the "correct" property as public
3. And then do the selection

Your code will look something like this

List<Answer> answers = new List<Answer>();
/* test
answers.Add(new Answer() { correct = false });
answers.Add(new Answer() { correct = true });
answers.Add(new Answer() { correct = false });
*/
Answer answer = answers.Single(a => a.correct == true);

and the class

class Answer
{
   public bool correct;
}

On most of UNIX based sys, its at /usr/bin/git (if installed with default options)
all git related scripts are at /usr/libexec/git-core

Indeed, the keyword is "ajax": Asynchronous JavaScript and XML. However, last years it's more than often Asynchronous JavaScript and JSON. Basically, you let JS execute an asynchronous HTTP request and update the HTML DOM tree based on the response data.

Since it's pretty a tedious work to make it to work across all browsers (especially Internet Explorer versus others), there are plenty of JavaScript libraries out which simplifies this in single functions and covers as many as possible browser-specific bugs/quirks under the hoods, such as jQuery, Prototype, Mootools. Since jQuery is most popular these days, I'll use it in the below examples.

Kickoff example returning String as plain text

Create a /some.jsp like below (note: the code snippets in this answer doesn't expect the JSP file being placed in a subfolder, if you do so, alter servlet URL accordingly from "someservlet" to "${pageContext.request.contextPath}/someservlet"; it's merely omitted from the code snippets for brevity):

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>SO question 4112686</title>
        <script src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script>
            $(document).on("click", "#somebutton", function() { // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
                $.get("someservlet", function(responseText) {   // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response text...
                    $("#somediv").text(responseText);           // Locate HTML DOM element with ID "somediv" and set its text content with the response text.
                });
            });
        </script>
    </head>
    <body>
        <button id="somebutton">press here</button>
        <div id="somediv"></div>
    </body>
</html>

Create a servlet with a doGet() method which look like this:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String text = "some text";

    response.setContentType("text/plain");  // Set content type of the response so that jQuery knows what it can expect.
    response.setCharacterEncoding("UTF-8"); // You want world domination, huh?
    response.getWriter().write(text);       // Write response body.
}

Map this servlet on an URL pattern of /someservlet or /someservlet/* as below (obviously, the URL pattern is free to your choice, but you'd need to alter the someservlet URL in JS code examples over all place accordingly):

package com.example;

@WebServlet("/someservlet/*")
public class SomeServlet extends HttpServlet {
    // ...
}

Or, when you're not on a Servlet 3.0 compatible container yet (Tomcat 7, Glassfish 3, JBoss AS 6, etc or newer), then map it in web.xml the old fashioned way (see also our Servlets wiki page):

<servlet>
    <servlet-name>someservlet</servlet-name>
    <servlet-class>com.example.SomeServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>someservlet</servlet-name>
    <url-pattern>/someservlet/*</url-pattern>
</servlet-mapping>

Now open the http://localhost:8080/context/test.jsp in the browser and press the button. You'll see that the content of the div get updated with the servlet response.

Returning List<String> as JSON

With JSON instead of plaintext as response format you can even get some steps further. It allows for more dynamics. First, you'd like to have a tool to convert between Java objects and JSON strings. There are plenty of them as well (see the bottom of this page for an overview). My personal favourite is Google Gson. Download and put its JAR file in /WEB-INF/lib folder of your webapplication.

Here's an example which displays List<String> as <ul><li>. The servlet:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    List<String> list = new ArrayList<>();
    list.add("item1");
    list.add("item2");
    list.add("item3");
    String json = new Gson().toJson(list);

    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

The JS code:

$(document).on("click", "#somebutton", function() {  // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseJson) {    // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response JSON...
        var $ul = $("<ul>").appendTo($("#somediv")); // Create HTML <ul> element and append it to HTML DOM element with ID "somediv".
        $.each(responseJson, function(index, item) { // Iterate over the JSON array.
            $("<li>").text(item).appendTo($ul);      // Create HTML <li> element, set its text content with currently iterated item and append it to the <ul>.
        });
    });
});

Do note that jQuery automatically parses the response as JSON and gives you directly a JSON object (responseJson) as function argument when you set the response content type to application/json. If you forget to set it or rely on a default of text/plain or text/html, then the responseJson argument wouldn't give you a JSON object, but a plain vanilla string and you'd need to manually fiddle around with JSON.parse() afterwards, which is thus totally unnecessary if you set the content type right in first place.

Returning Map<String, String> as JSON

Here's another example which displays Map<String, String> as <option>:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    Map<String, String> options = new LinkedHashMap<>();
    options.put("value1", "label1");
    options.put("value2", "label2");
    options.put("value3", "label3");
    String json = new Gson().toJson(options);

    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

And the JSP:

$(document).on("click", "#somebutton", function() {               // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseJson) {                 // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response JSON...
        var $select = $("#someselect");                           // Locate HTML DOM element with ID "someselect".
        $select.find("option").remove();                          // Find all child elements with tag name "option" and remove them (just to prevent duplicate options when button is pressed again).
        $.each(responseJson, function(key, value) {               // Iterate over the JSON object.
            $("<option>").val(key).text(value).appendTo($select); // Create HTML <option> element, set its value with currently iterated key and its text content with currently iterated item and finally append it to the <select>.
        });
    });
});

with

<select id="someselect"></select>

Returning List<Entity> as JSON

Here's an example which displays List<Product> in a <table> where the Product class has the properties Long id, String name and BigDecimal price. The servlet:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    List<Product> products = someProductService.list();
    String json = new Gson().toJson(products);

    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

The JS code:

$(document).on("click", "#somebutton", function() {        // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseJson) {          // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response JSON...
        var $table = $("<table>").appendTo($("#somediv")); // Create HTML <table> element and append it to HTML DOM element with ID "somediv".
        $.each(responseJson, function(index, product) {    // Iterate over the JSON array.
            $("<tr>").appendTo($table)                     // Create HTML <tr> element, set its text content with currently iterated item and append it to the <table>.
                .append($("<td>").text(product.id))        // Create HTML <td> element, set its text content with id of currently iterated product and append it to the <tr>.
                .append($("<td>").text(product.name))      // Create HTML <td> element, set its text content with name of currently iterated product and append it to the <tr>.
                .append($("<td>").text(product.price));    // Create HTML <td> element, set its text content with price of currently iterated product and append it to the <tr>.
        });
    });
});

Returning List<Entity> as XML

Here's an example which does effectively the same as previous example, but then with XML instead of JSON. When using JSP as XML output generator you'll see that it's less tedious to code the table and all. JSTL is this way much more helpful as you can actually use it to iterate over the results and perform server side data formatting. The servlet:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    List<Product> products = someProductService.list();

    request.setAttribute("products", products);
    request.getRequestDispatcher("/WEB-INF/xml/products.jsp").forward(request, response);
}

The JSP code (note: if you put the <table> in a <jsp:include>, it may be reusable elsewhere in a non-ajax response):

<?xml version="1.0" encoding="UTF-8"?>
<%@page contentType="application/xml" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<data>
    <table>
        <c:forEach items="${products}" var="product">
            <tr>
                <td>${product.id}</td>
                <td><c:out value="${product.name}" /></td>
                <td><fmt:formatNumber value="${product.price}" type="currency" currencyCode="USD" /></td>
            </tr>
        </c:forEach>
    </table>
</data>

The JS code:

$(document).on("click", "#somebutton", function() {             // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseXml) {                // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response XML...
        $("#somediv").html($(responseXml).find("data").html()); // Parse XML, find <data> element and append its HTML to HTML DOM element with ID "somediv".
    });
});

You'll by now probably realize why XML is so much more powerful than JSON for the particular purpose of updating a HTML document using Ajax. JSON is funny, but after all generally only useful for so-called "public web services". MVC frameworks like JSF use XML under the covers for their ajax magic.

Ajaxifying an existing form

You can use jQuery $.serialize() to easily ajaxify existing POST forms without fiddling around with collecting and passing the individual form input parameters. Assuming an existing form which works perfectly fine without JavaScript/jQuery (and thus degrades gracefully when enduser has JavaScript disabled):

<form id="someform" action="someservlet" method="post">
    <input type="text" name="foo" />
    <input type="text" name="bar" />
    <input type="text" name="baz" />
    <input type="submit" name="submit" value="Submit" />
</form>

You can progressively enhance it with ajax as below:

$(document).on("submit", "#someform", function(event) {
    var $form = $(this);

    $.post($form.attr("action"), $form.serialize(), function(response) {
        // ...
    });

    event.preventDefault(); // Important! Prevents submitting the form.
});

You can in the servlet distinguish between normal requests and ajax requests as below:

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String foo = request.getParameter("foo");
    String bar = request.getParameter("bar");
    String baz = request.getParameter("baz");

    boolean ajax = "XMLHttpRequest".equals(request.getHeader("X-Requested-With"));

    // ...

    if (ajax) {
        // Handle ajax (JSON or XML) response.
    } else {
        // Handle regular (JSP) response.
    }
}

The jQuery Form plugin does less or more the same as above jQuery example, but it has additional transparent support for multipart/form-data forms as required by file uploads.

Manually sending request parameters to servlet

If you don't have a form at all, but just wanted to interact with the servlet "in the background" whereby you'd like to POST some data, then you can use jQuery $.param() to easily convert a JSON object to an URL-encoded query string.

var params = {
    foo: "fooValue",
    bar: "barValue",
    baz: "bazValue"
};

$.post("someservlet", $.param(params), function(response) {
    // ...
});

The same doPost() method as shown here above can be reused. Do note that above syntax also works with $.get() in jQuery and doGet() in servlet.

Manually sending JSON object to servlet

If you however intend to send the JSON object as a whole instead of as individual request parameters for some reason, then you'd need to serialize it to a string using JSON.stringify() (not part of jQuery) and instruct jQuery to set request content type to application/json instead of (default) application/x-www-form-urlencoded. This can't be done via $.post() convenience function, but needs to be done via $.ajax() as below.

var data = {
    foo: "fooValue",
    bar: "barValue",
    baz: "bazValue"
};

$.ajax({
    type: "POST",
    url: "someservlet",
    contentType: "application/json", // NOT dataType!
    data: JSON.stringify(data),
    success: function(response) {
        // ...
    }
});

Do note that a lot of starters mix contentType with dataType. The contentType represents the type of the request body. The dataType represents the (expected) type of the response body, which is usually unnecessary as jQuery already autodetects it based on response's Content-Type header.

Then, in order to process the JSON object in the servlet which isn't being sent as individual request parameters but as a whole JSON string the above way, you only need to manually parse the request body using a JSON tool instead of using getParameter() the usual way. Namely, servlets don't support application/json formatted requests, but only application/x-www-form-urlencoded or multipart/form-data formatted requests. Gson also supports parsing a JSON string into a JSON object.

JsonObject data = new Gson().fromJson(request.getReader(), JsonObject.class);
String foo = data.get("foo").getAsString();
String bar = data.get("bar").getAsString();
String baz = data.get("baz").getAsString();
// ...

Do note that this all is more clumsy than just using $.param(). Normally, you want to use JSON.stringify() only if the target service is e.g. a JAX-RS (RESTful) service which is for some reason only capable of consuming JSON strings and not regular request parameters.

Sending a redirect from servlet

Important to realize and understand is that any sendRedirect() and forward() call by the servlet on an ajax request would only forward or redirect the ajax request itself and not the main document/window where the ajax request originated. JavaScript/jQuery would in such case only retrieve the redirected/forwarded response as responseText variable in the callback function. If it represents a whole HTML page and not an ajax-specific XML or JSON response, then all you could do is to replace the current document with it.

document.open();
document.write(responseText);
document.close();

Note that this doesn't change the URL as enduser sees in browser's address bar. So there are issues with bookmarkability. Therefore, it's much better to just return an "instruction" for JavaScript/jQuery to perform a redirect instead of returning the whole content of the redirected page. E.g. by returning a boolean, or an URL.

String redirectURL = "http://example.com";

Map<String, String> data = new HashMap<>();
data.put("redirect", redirectURL);
String json = new Gson().toJson(data);

response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);

function(responseJson) {
    if (responseJson.redirect) {
        window.location = responseJson.redirect;
        return;
    }

    // ...
}

As mentioned already, Blazemongers solution is failing to remove quotes (e.g. returned by Firefox). Since I find Rob Ws solution to be rather complicated, adding my 2 cents here:

$('#div1').click (function(){
  url = $(this).css('background-image').replace(/^url\(['"]?/,'').replace(/['"]?\)$/,'');
  alert(url);
})

If you are using setup tools or distribute (a setup.py install) then the "right" way to access these packaged resources seem to be using package_resources.

In your case the example would be

import pkg_resources
my_data = pkg_resources.resource_string(__name__, "foo.dat")

Which of course reads the resource and the read binary data would be the value of my_data

If you just need the filename you could also use

resource_filename(package_or_requirement, resource_name)

Example:

resource_filename("MyPackage","foo.dat")

The advantage is that its guaranteed to work even if it is an archive distribution like an egg.

See http://packages.python.org/distribute/pkg_resources.html#resourcemanager-api

var intArray = [1, 2, 3, 4, 5];
//lets use each function
$.each(intArray, function(index, element) {
  if (element === 3) {
    return false;
  }
  console.log(element); // prints only 1,2. Breaks the loop as soon as it encountered number 3
});

//lets use map function
$.map(intArray, function(element, index) {
  if (element === 3) {
    return false;
  }
  console.log(element); // prints only 1,2,4,5. skip the number 3.
});

If you're using jQuery, you have .trim().

if ($("#siren").val().trim() == "") {
  // it's empty
}

Oddly enough, this works for me (when I place inside a button tag).

.button {
    position: relative;

    input[type=file] {
            color: transparent;
            background-color: transparent;
            position: absolute;
            left: 0;
            width: 100%;
            height: 100%;
            top: 0;
            opacity: 0;
            z-index: 100;
        }
}

Only tested in Chrome (macOS Sierra).

Unless your compiler is different than the one supplied with the Mac XCode Dev tools, just follow the instructions in section 5.1 of Getting Started Guide for Unix Variants. The configuration and building of the latest source couldn't be easier, and it took all about about 1 minute to configure and 10 minutes to compile.

if you need to add a date-time to your backup file name (Centos7) use the following:

/usr/bin/mysqldump -u USER -pPASSWD DBNAME | gzip > ~/backups/db.$(date +%F.%H%M%S).sql.gz

this will create the file: db.2017-11-17.231537.sql.gz

Another solution without background image and without the need for a container (though the max sizes of the bounding box must be known):

img{
  max-height: 100px;
  max-width: 100px;
  width: auto;    /* These two are added only for clarity, */
  height: auto;   /* as the default is auto anyway */
}

img {
    max-height: 100%;
    max-width: 100%;
    width: auto; /* These two are added only for clarity, */
    height: auto; /* as the default is auto anyway */
}

div.container {
    width: 100px;
    height: 100px;
}

For this you would have something like:

<table>
    <tr>
        <td>Lorem</td>
        <td>Ipsum<br />dolor</td>
        <td>
            <div class="container"><img src="image5.png" /></div>
        </td>
    </tr>
</table>

If our CustomTableSeeder is in same directory with DatabaseSeeder we should use like below:

$this->call('database\seeds\CustomTableSeeder');

in our DatabaseSeeder File; then another error will be thrown that says: 'DB Class not found' then we should add our DB facade to our CustomTableSeeder File like below:

use Illuminate\Support\Facades\DB;

it worked for me!

SELECT student, (SUM(mark1)+SUM(mark2)+SUM(mark3)....+SUM(markn)) AS Total

Use std::map<OS_type, std::string> and populate it with enum as key, and string representation as values, then you can do these:

printf("My OS is %s", enumMap[myOS].c_str());
std::cout << enumMap[myOS] ;

If you add:

jquery.form.min.js

You can simply do this:

<script>
$('#myform').ajaxForm(function(response) {
  alert(response);
});

// this will register the AJAX for <form id="myform" action="some_url">
// and when you submit the form using <button type="submit"> or $('myform').submit(), then it will send your request and alert response
</script>

NOTE:

You could use simple $('FORM').serialize() as suggested in post above, but that will not work for FILE INPUTS... ajaxForm() will.

In addition to @Boaz's and @vegemite4me's answers....

By implementing ImplicitNamingStrategy you may create rules for automatically naming the constraints. Note you add your naming strategy to the metadataBuilder during Hibernate's initialization:

metadataBuilder.applyImplicitNamingStrategy(new MyImplicitNamingStrategy());

It works for @UniqueConstraint, but not for @Column(unique = true), which always generates a random name (e.g. UK_3u5h7y36qqa13y3mauc5xxayq).

There is a bug report to solve this issue, so if you can, please vote there to have this implemented. Here: https://hibernate.atlassian.net/browse/HHH-11586

Thanks.

It's because you haven't declared outchar before you use it. That means that the compiler will assume it's a function returning an int and taking an undefined number of undefined arguments.

You need to add a prototype pf the function before you use it:

void outchar(char);  /* Prototype (declaration) of a function to be called */  int main(void) {     ... }  void outchar(char ch) {     ... } 

Note the declaration of the main function differs from your code as well. It's actually a part of the official C specification, it must return an int and must take either a void argument or an int and a char** argument.

Dont know, why you want to use &&. Theres an easier solution

echo in_array($var, array('abc', 'def', 'hij', 'klm', 'nop'))
      ? 'yes' 
      : 'no';

You can use this or refer further this https://select2.org/programmatic-control/add-select-clear-items

$('#mySelect2').val(null).trigger('change');

I want to mention here a very, VERY, interesting technique that is being used in huge projects like jQuery and Modernizr for concatenate things.

Both of this projects are entirely developed with requirejs modules (you can see that in their github repos) and then they use the requirejs optimizer as a very smart concatenator. The interesting thing is that, as you can see, nor jQuery neither Modernizr needs on requirejs to work, and this happen because they erase the requirejs syntatic ritual in order to get rid of requirejs in their code. So they end up with a standalone library that was developed with requirejs modules! Thanks to this they are able to perform cutsom builds of their libraries, among other advantages.

For all those interested in concatenation with the requirejs optimizer, check out this post

Also there is a small tool that abstracts all the boilerplate of the process: AlbanilJS

You can also install any of the Hardware IO Tools without installing XCode itself. Simply visit Apple's Download Center and search for "Hardware IO".

Using the builtin Date.parse function which accepts input in ISO8601 format and directly returns the desired integer return value:

var dates_as_int = dates.map(Date.parse);

%d prints an integer: it will print the ascii representation of your character. What you need is %c:

printf("%c", ch);

printf("%d", '\0'); prints the ascii representation of '\0', which is 0 (by escaping 0 you tell the compiler to use the ascii value 0.

printf("%d", sizeof('\n')); prints 4 because a character literal is an int, in C, and not a char.

Try:

select
     id,
     StartDate,
CASE WHEN StartDate IS NULL
    THEN 'Awaiting'
    ELSE 'Approved' END AS StartDateStatus
FROM myTable

You code would have been doing a When StartDate = NULL, I think.

NULL is never equal to NULL (as NULL is the absence of a value). NULL is also never not equal to NULL. The syntax noted above is ANSI SQL standard and the converse would be StartDate IS NOT NULL.

You can run the following:

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

And this returns:

EqualityCheck = 0
InEqualityCheck = 0
NullComparison = 1

For completeness, in SQL Server you can:

SET ANSI_NULLS OFF;

Which would result in your equals comparisons working differently:

SET ANSI_NULLS OFF

SELECT CASE WHEN (NULL = NULL) THEN 1 ELSE 0 END AS EqualityCheck,
CASE WHEN (NULL <> NULL) THEN 1 ELSE 0 END AS InEqualityCheck,
CASE WHEN (NULL IS NULL) THEN 1 ELSE 0 END AS NullComparison

Which returns:

EqualityCheck = 1
InEqualityCheck = 0
NullComparison = 1

But I would highly recommend against doing this. People subsequently maintaining your code might be compelled to hunt you down and hurt you...

Also, it will no longer work in upcoming versions of SQL server:

https://msdn.microsoft.com/en-GB/library/ms188048.aspx

You can use Calendar's method

func date(byAdding component: Calendar.Component, value: Int, to date: Date, wrappingComponents: Bool = default) -> Date?

to add any Calendar.Component to any Date. You can create a Date extension to add x minutes to your UIDatePicker's date:

Xcode 8 and Xcode 9 • Swift 3.0 and Swift 4.0

extension Date {
    func adding(minutes: Int) -> Date {
        return Calendar.current.date(byAdding: .minute, value: minutes, to: self)!
    }
}

Then you can just use the extension method to add minutes to the sender (UIDatePicker):

let section1 = sender.date.adding(minutes: 5)
let section2 = sender.date.adding(minutes: 10)

Playground testing:

Date().adding(minutes: 10)  //  "Jun 14, 2016, 5:31 PM"

If its text that has to scale proportionally to the screenwidth, you can also use the font as an svg, you can just export it from something like illustrator. I had to do this in my case, because I wanted to align the top of left and right border with the font's top |TEXT| . Using line-height, the text will jump up and down when scaling the window.

I use this Bash script to test the internet status every minute on OSX

#address=192.168.1.99  # forced bad address for testing/debugging

while true;
do
    # %a  Day of Week, textual
    # %b  Month, textual, abbreviated
    # %d  Day, numeric
    # %r  Timestamp AM/PM
    echo -n $(date +"%a, %b %d, %r") "-- " 
    ping -c 1 ${address} > /tmp/ping.$
    if [[ $? -ne 0 ]]; then
        if [[ ${internet} -eq 1 ]]; then   # edge trigger -- was up now down
            echo -n $(say "Internet down") # OSX Text-to-Speech
            echo -n "Internet DOWN"
        else
            echo -n "... still down"
        fi
        internet=0
    else
        if [[ ${internet} -eq 0 ]]; then     # edge trigger -- was down now up
            echo -n $(say "Internet back up") # OSX Text-To-Speech
        fi
        internet=1
    fi   
    cat /tmp/ping.$ | head -2 | tail -1
    sleep 60 ; # sleep 60 seconds =1 min
done

The code yo have provided runs fine. Remember that if you have your code in the header, you need to wait for the dom to be loaded first. In jQuery it would just be as simple as putting your code inside $(function(e){...});

In normal javascript use window.onLoad(..) or the like... or have the script after the table defnition (yuck!). The snippet you provided runs fine when I have it that way for the following:

<html>
<head>
  <meta http-equiv="content-type" content="text/html; charset=windows-1250">
  <meta name="generator" content="PSPad editor, www.pspad.com">
  <title></title>
</head>
<body>
  <table id='ddReferences'>
    <tr>
      <td>dfsdf</td> 
      <td>sdfs</td>
      <td>frtyr</td>
      <td>hjhj</td>
    </tr>
  </table>

<script>
var refTab = document.getElementById("ddReferences")
var  ttl;
// Loop through all rows and columns of the table and popup alert with the value
// /content of each cell.
for ( var i = 0; row = refTab.rows[i]; i++ ) {
   row = refTab.rows[i];
   for ( var j = 0; col = row.cells[j]; j++ ) {
      alert(col.firstChild.nodeValue);
   }
}

</script>
</body>
</html>

Try to enable the Bypass proxy server for local addresses. This works for all browsers installed (Firefox, Chrome, etc).

1. Open Internet Explorer by clicking the Start button Picture of the Start button. In the search box, type Internet Explorer, and then, in the list of results, click Internet Explorer.

2. Click the Tools button, and then click Internet Options.

3. Click the Connections tab, and then click LAN settings.

4. Select the Use a proxy server for your LAN check box.

5. Select the Bypass proxy server for local addresses

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

Try this:

.slideContainer {_x000D_
    overflow-x: scroll;_x000D_
    white-space: nowrap;_x000D_
}_x000D_
.slide {_x000D_
    display: inline-block;_x000D_
    width: 600px;_x000D_
    white-space: normal;_x000D_
}

<div class="slideContainer">_x000D_
    <span class="slide">Some content</span>_x000D_
    <span class="slide">More content. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</span>_x000D_
    <span class="slide">Even more content!</span>_x000D_
</div>

Note that you can omit .slideContainer { overflow-x: scroll; } (which browsers may or may not support when you read this), and you'll get a scrollbar on the window instead of on this container.

The key here is display: inline-block. This has decent cross-browser support nowadays, but as usual, it's worth testing in all target browsers to be sure.

In case you want to train CNN's with the theano backend like the Keras mnist_cnn.py example:

You better use theano bleeding edge version. Otherwise there may occur assertion errors.

• Run Theano bleeding edge
  pip install --upgrade --no-deps git+git://github.com/Theano/Theano.git
• Run Keras (like 1.0.8 works fine)
  pip install git+git://github.com/fchollet/keras.git

$('input[type=text],select', '.sys');

for looping:

$('input[type=text],select', '.sys').each(function() {
   // code
});

In ubuntu, we can find all password related to keystore from the given path.

/home/user/.AndroidStudio2.2(current version)/system/log/idea.log.x(older versions)

edit the file and search android.injected.signing.store , then you can find the passwords.

-Pandroid.injected.signing.store.file= path to your keystore 
-Pandroid.injected.signing.store.password=yourstorepassword
-Pandroid.injected.signing.key.alias=yourkeyalias
-Pandroid.injected.signing.key.password=yourkeypassword

With Python 3.8 this workes for me. For instance to execute a python script within the venv:

    import subprocess
    import sys
    res = subprocess.run([
              sys.executable,            # venv3.8/bin/python
              'main.py', '--help',], 
            stdout=PIPE, 
            text=True)
    print(res.stdout)

SELECT COUNT(*) FROM information_schema.tables

nvarchar(max) is what you want to be using. The biggest advantage is that you can use all the T-SQL string functions on this data type. This is not possible with ntext. I'm not aware of any real disadvantages.

in first.java

Intent i = new Intent(this, second.class);
                    i.putExtra("uri",uri);
                    startActivity(i);

in second.java

Bundle bd = getIntent().getExtras();
        Uri uri = bd.getParcelable("uri");
        Log.e("URI", uri.toString());
        try {
            Bitmap bitmap = Media.getBitmap(this.getContentResolver(), uri);
            imageView.setImageBitmap(bitmap);

        } 
        catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

You can create your own extension method to do this:

public static bool Contains(this string source, string toCheck, StringComparison comp)
  {
    return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
  }

And then call:

 mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);

The gdi32 library is already installed on your computer, few programs will run without it. Your compiler will (if installed properly) normally come with an import library, which is what the linker uses to make a binding between your program and the file in the system. (In the unlikely case that your compiler does not come with import libraries for the system libs, you will need to download the Microsoft Windows Platform SDK.)

To link with gdi32:

This will reliably work with MinGW-gcc for all system libraries (it should work if you use any other compiler too, but I can't talk about things I've not tried). You can also write the library's full name, but writing libgdi32.a has no advantage over gdi32 other than being more type work.
If it does not work for some reason, you may have to provide a different name (for example the library is named gdi32.lib for MSVC).

For libraries in some odd locations or project subfolders, you will need to provide a proper pathname (click on the "..." button for a file select dialog).

Uninstall Java (via Control Panel / Programs and Features)

Install Java JRE 7 --> OFFLINE <-- Configure JAVA_HOME and Path = %JAVA_HOME%/bin;%PATH%

Having rolled my own solution for this before, I can whole heartedly recommend the Geo::Coder::US Perl module for this. Just download all the census data and use the included importer to create the Berkeley DB for your country and point the Perl script at it. Use the module's built in address parsing, and there you have it: An offline geocoding system!

Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.

Having added a new view controller scene to your storyboard, you then have to:

1. Create a UIViewController subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":

   

   And then select a unique name for the new view controller subclass:

   

2. Specify this new subclass as the base class for the scene you just added to the storyboard.

   

3. Now hook up any IBOutlet and IBAction references for this new scene with the new view controller subclass.

This one shows the user's uid as well as all the groups (with their gids) they belong to

To represent a unicode string as a string of bytes is known as encoding. Use u'...'.encode(encoding).

Example:

    >>> u'æøå'.encode('utf8')
    '\xc3\x83\xc2\xa6\xc3\x83\xc2\xb8\xc3\x83\xc2\xa5'
    >>> u'æøå'.encode('latin1')
    '\xc3\xa6\xc3\xb8\xc3\xa5'
    >>> u'æøå'.encode('ascii')
    UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-5: 
    ordinal not in range(128)

You typically encode a unicode string whenever you need to use it for IO, for instance transfer it over the network, or save it to a disk file.

To convert a string of bytes to a unicode string is known as decoding. Use unicode('...', encoding) or '...'.decode(encoding).

Example:

   >>> u'æøå'
   u'\xc3\xa6\xc3\xb8\xc3\xa5' # the interpreter prints the unicode object like so
   >>> unicode('\xc3\xa6\xc3\xb8\xc3\xa5', 'latin1')
   u'\xc3\xa6\xc3\xb8\xc3\xa5'
   >>> '\xc3\xa6\xc3\xb8\xc3\xa5'.decode('latin1')
   u'\xc3\xa6\xc3\xb8\xc3\xa5'

You typically decode a string of bytes whenever you receive string data from the network or from a disk file.

I believe there are some changes in unicode handling in python 3, so the above is probably not correct for python 3.

Some good links:

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)
• Unicode HOWTO

I recommend the method given by doofledorfer.

If you really want to do it via a direct API call, then look at the OpenSCManager function. Below are sample functions to take a machine name and service, and stop or start them.

function ServiceStart(sMachine, sService : string) : boolean;  //start service, return TRUE if successful
var schm, schs : SC_Handle;
    ss         : TServiceStatus;
    psTemp     : PChar;
    dwChkP     : DWord;
begin
  ss.dwCurrentState := 0;
  schm := OpenSCManager(PChar(sMachine),Nil,SC_MANAGER_CONNECT);  //connect to the service control manager

  if(schm > 0)then begin // if successful...
    schs := OpenService( schm,PChar(sService),SERVICE_START or SERVICE_QUERY_STATUS);    // open service handle, start and query status
    if(schs > 0)then begin     // if successful...
      psTemp := nil;
      if (StartService(schs,0,psTemp)) and (QueryServiceStatus(schs,ss)) then
        while(SERVICE_RUNNING <> ss.dwCurrentState)do begin
          dwChkP := ss.dwCheckPoint;  //dwCheckPoint contains a value incremented periodically to report progress of a long operation.  Store it.
          Sleep(ss.dwWaitHint);  //Sleep for recommended time before checking status again
          if(not QueryServiceStatus(schs,ss))then
            break;  //couldn't check status
          if(ss.dwCheckPoint < dwChkP)then
            Break;  //if QueryServiceStatus didn't work for some reason, avoid infinite loop
        end;  //while not running
      CloseServiceHandle(schs);
    end;  //if able to get service handle
    CloseServiceHandle(schm);
  end;  //if able to get svc mgr handle
  Result := SERVICE_RUNNING = ss.dwCurrentState;  //if we were able to start it, return true
end;

function ServiceStop(sMachine, sService : string) : boolean;  //stop service, return TRUE if successful
var schm, schs : SC_Handle;
    ss         : TServiceStatus;
    dwChkP     : DWord;
begin
  schm := OpenSCManager(PChar(sMachine),nil,SC_MANAGER_CONNECT);

  if(schm > 0)then begin
    schs := OpenService(schm,PChar(sService),SERVICE_STOP or SERVICE_QUERY_STATUS);
    if(schs > 0)then begin
      if (ControlService(schs,SERVICE_CONTROL_STOP,ss)) and (QueryServiceStatus(schs,ss)) then
        while(SERVICE_STOPPED <> ss.dwCurrentState) do begin
          dwChkP := ss.dwCheckPoint;
          Sleep(ss.dwWaitHint);
          if(not QueryServiceStatus(schs,ss))then
            Break;

          if(ss.dwCheckPoint < dwChkP)then
            Break;
        end;  //while
      CloseServiceHandle(schs);
    end;  //if able to get svc handle
    CloseServiceHandle(schm);
  end;  //if able to get svc mgr handle
  Result := SERVICE_STOPPED = ss.dwCurrentState;
end;

To start a program and then close command prompt without waiting for program to exit:

start /d "path" file.exe

You have to give height and width to that image.

eg. height : 200px and width : 200px also give border-radius:50%;

to create circle you have to give equal height and width

if you are using bootstrap then give height and width and img-circle class to img

C++11 standard on jumping over some initializations

JohannesD gave an explanation, now for the standards.

The C++11 N3337 standard draft 6.7 "Declaration statement" says:

3 It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps (87) from a point where a variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has scalar type, class type with a trivial default constructor and a trivial destructor, a cv-qualified version of one of these types, or an array of one of the preceding types and is declared without an initializer (8.5).

87) The transfer from the condition of a switch statement to a case label is considered a jump in this respect.

[ Example:

void f() {
   // ...
  goto lx;    // ill-formed: jump into scope of a
  // ...
ly:
  X a = 1;
  // ...
lx:
  goto ly;    // OK, jump implies destructor
              // call for a followed by construction
              // again immediately following label ly
}

— end example ]

As of GCC 5.2, the error message now says:

crosses initialization of

C

C allows it: c99 goto past initialization

The C99 N1256 standard draft Annex I "Common warnings" says:

2 A block with initialization of an object that has automatic storage duration is jumped into

I was able to use Paco Zarate's solution and it works beautifully. I did have to add one line ("SET ANSI_WARNINGS ON"), but that may be something unique to the way I used it or called it. There is a problem with my usage and I hope someone can help me with it:

The solution works only with an actual SQL table. I tried it with a temporary table and also an in-memory (declared) table but it doesn't work with those. So in my calling code I create a table on my SQL database and then call SQLTranspose. Again, it works great. It's just what I want. Here's my problem:

In order for the overall solution to be truly dynamic I need to create that table where I temporarily store the prepared information that I'm sending to SQLTranspose "on the fly", and then delete that table once SQLTranspose is called. The table deletion is presenting a problem with my ultimate implementation plan. The code needs to run from an end-user application (a button on a Microsoft Access form/menu). When I use this SQL process (create a SQL table, call SQLTranspose, delete SQL table) the end user application hits an error because the SQL account used does not have the rights to drop a table.

So I figure there are a few possible solutions:

1. Find a way to make SQLTranspose work with a temporary table or a declared table variable.

2. Figure out another method for the transposition of rows and columns that doesn't require an actual SQL table.

3. Figure out an appropriate method of allowing the SQL account used by my end users to drop a table. It's a single shared SQL account coded into my Access application. It appears that permission is a dbo-type privilege that cannot be granted.

I recognize that some of this may warrant another, separate thread and question. However, since there is a possibility that one solution may be simply a different way to do the transposing of rows and columns I'll make my first post here in this thread.

EDIT: I also did replace sum(value) with max(value) in the 6th line from the end, as Paco suggested.

EDIT:

I figured out something that works for me. I don't know if it's the best answer or not.

I have a read-only user account that is used to execute strored procedures and therefore generate reporting output from a database. Since the SQLTranspose function I created will only work with a "legitimate" table (not a declared table and not a temporary table) I had to figure out a way for a read-only user account to create (and then later delete) a table.

I reasoned that for my purposes it's okay for the user account to be allowed to create a table. The user still could not delete the table though. My solution was to create a schema where the user account is authorized. Then whenever I create, use, or delete that table refer it with the schema specified.

I first issued this command from a 'sa' or 'sysadmin' account: CREATE SCHEMA ro AUTHORIZATION

When any time I refer to my "tmpoutput" table I specify it like this example:

drop table ro.tmpoutput

You can increase client_max_body_size and upload_max_filesize + post_max_size all day long. Without adjusting HTTP timeout it will never work.

//You need to adjust this, and probably on PHP side also. client_body_timeout 2min // 1GB fileupload

This is very confusing part for newbie and I have tried to clarify it in easy words

AngularJS Service: is used for sharing utility functions with the service reference in the controller. Service is singleton in nature so for one service only one instance is created in the browser and the same reference is used throughout the page.

In the service, we create function names as property with this object.

AngularJS Factory: the purpose of Factory is also same as Service however in this case we create a new object and add functions as properties of this object and at the end we return this object.

AngularJS Provider: the purpose of this is again same however Provider gives the output of it's $get function.

Defining and using Service, Factory and Provider are explained at http://www.dotnetfunda.com/articles/show/3156/difference-between-angularjs-service-factory-and-provider

Modern answer and overview

a) Java-8 (java.time-package)

LocalDate start = LocalDate.of(1996, 2, 29);
LocalDate end = LocalDate.of(2014, 2, 28); // use for age-calculation: LocalDate.now()
long years = ChronoUnit.YEARS.between(start, end);
System.out.println(years); // 17

Note that the expression LocalDate.now() is implicitly related to the system timezone (which is often overlooked by users). For clarity it is generally better to use the overloaded method now(ZoneId.of("Europe/Paris")) specifying an explicit timezone (here "Europe/Paris" as example). If the system timezone is requested then my personal preference is to write LocalDate.now(ZoneId.systemDefault()) to make the relation to the system timezone clearer. This is more writing effort but makes reading easier.

b) Joda-Time

Please note that the proposed and accepted Joda-Time-solution yields a different computation result for the dates shown above (a rare case), namely:

LocalDate birthdate = new LocalDate(1996, 2, 29);
LocalDate now = new LocalDate(2014, 2, 28); // test, in real world without args
Years age = Years.yearsBetween(birthdate, now);
System.out.println(age.getYears()); // 18

I consider this as a small bug but the Joda-team has a different view on this weird behaviour and does not want to fix it (weird because the day-of-month of end date is smaller than of start date so the year should be one less). See also this closed issue.

c) java.util.Calendar etc.

For comparison see the various other answers. I would not recommend using these outdated classes at all because the resulting code is still errorprone in some exotic cases and/or way too complex considering the fact that the original question sounds so simple. In year 2015 we have really better libraries.

d) About Date4J:

The proposed solution is simple but will sometimes fail in case of leap years. Just evaluating the day of year is not reliable.

e) My own library Time4J:

This works similar to Java-8-solution. Just replace LocalDate by PlainDate and ChronoUnit.YEARS by CalendarUnit.YEARS. However, getting "today" requires an explicit timezone reference.

PlainDate start = PlainDate.of(1996, 2, 29);
PlainDate end = PlainDate.of(2014, 2, 28);
// use for age-calculation (today): 
// => end = SystemClock.inZonalView(EUROPE.PARIS).today();
// or in system timezone: end = SystemClock.inLocalView().today();
long years = CalendarUnit.YEARS.between(start, end);
System.out.println(years); // 17

It seems like you want

wait $PID

which will return when $pid finishes.

Otherwise you can use

ps -p $PID

to check if the process is still alive (this is more effective than kill -0 $pid because it will work even if you don't own the pid).

If you know how far back, you can try something like:

# Current branch vs. parent
git diff HEAD^ HEAD

# Current branch, diff between commits 2 and 3 times back
git diff HEAD~3 HEAD~2

Prior commits work something like this:

# Parent of HEAD
git show HEAD^1

# Grandparent
git show HEAD^2

There are a lot of ways you can specify commits:

# Great grandparent
git show HEAD~3

See this page for details.

PAGEIOLATCH_SH wait type usually comes up as the result of fragmented or unoptimized index.

Often reasons for excessive PAGEIOLATCH_SH wait type are:

• I/O subsystem has a problem or is misconfigured
• Overloaded I/O subsystem by other processes that are producing the high I/O activity
• Bad index management
• Logical or physical drive misconception
• Network issues/latency
• Memory pressure
• Synchronous Mirroring and AlwaysOn AG

In order to try and resolve having high PAGEIOLATCH_SH wait type, you can check:

• SQL Server, queries and indexes, as very often this could be found as a root cause of the excessive PAGEIOLATCH_SH wait types
• For memory pressure before jumping into any I/O subsystem troubleshooting

Always keep in mind that in case of high safety Mirroring or synchronous-commit availability in AlwaysOn AG, increased/excessive PAGEIOLATCH_SH can be expected.

You can find more details about this topic in the article Handling excessive SQL Server PAGEIOLATCH_SH wait types

Python docs has an answer that covers +/-, and exponent notation

scanf() Token      Regular Expression
%e, %E, %f, %g     [-+]?(\d+(\.\d*)?|\.\d+)([eE][-+]?\d+)?
%i                 [-+]?(0[xX][\dA-Fa-f]+|0[0-7]*|\d+)

This regular expression does not support international formats where a comma is used as the separator character between the whole and fractional part (3,14159). In that case, replace all \. with [.,] in the above float regex.

Please use DateTimeFormatter ISO_DATE_TIME = DateTimeFormatter.ISO_DATE_TIME; instead of DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm:ss") or any pattern

This fixed my problem Below

If it isn't I could see things heading that way.

I'm working on redoing the website for the company I work for and the designer they hired used a 960px width layout. There is also a 960px grid system that seems to be getting quite popular (http://960.gs/).

I've been out of web stuff for a few years but from what I've read catching up on things it seems 960/980 is about right. For mobile ~320px sticks in my mind, by which 960 is divisible. 960 is also evenly divisible by 2, 3, 4, 5, and 6.

There is a solution to solve page_onload problem (can't get size until page load complete) : Create a userControl :

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="ClientSizeDetector.ascx.vb"    Inherits="Project_UserControls_ClientSizeDetector" %>
<%If (IsFirstTime) Then%>
<script type="text/javascript">
var pageURL = window.location.href.search(/\?/) > 0 ? "&" : "?";
window.location.href = window.location.href + pageURL + "clientHeight=" + window.innerHeight + "&clientWidth=" + window.innerWidth;
</script>
<%End If%>

Code behind :

 Private _isFirstTime As Boolean = False
 Private _clientWidth As Integer = 0
 Private _clientHeight As Integer = 0

 Public Property ClientWidth() As Integer
    Get
        Return _clientWidth
    End Get
    Set(value As Integer)
        _clientWidth = value
    End Set
End Property

Public Property ClientHeight() As Integer
    Get
        Return _clientHeight
    End Get
    Set(value As Integer)
        _clientHeight = value
    End Set
End Property

public Property IsFirstTime() As Boolean 
    Get
        Return _isFirstTime
    End Get
    Set(value As Boolean)
        _isFirstTime = value
    End Set
End Property



Protected Overrides Sub OnInit(e As EventArgs)

    If (String.IsNullOrEmpty(Request.QueryString("clientHeight")) Or String.IsNullOrEmpty(Request.QueryString("clientWidth"))) Then
        Me._isFirstTime = True
    Else
        Integer.TryParse(Request.QueryString("clientHeight").ToString(), ClientHeight)
        Integer.TryParse(Request.QueryString("clientWidth").ToString(), ClientWidth)
        Me._isFirstTime = False
    End If
End Sub

So after, you can call your control properties

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

• First, install forever.

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

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

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

IN windows open cmd

go to directory where your netbeans downloaded

then run below command JDK path may be different from the path I mentioned

netbeans-8.2-windows.exe --javahome "C:\Program Files\Java\jdk-9.0.1"

if you face issue in existing installed in netbeans you can find details in here

As per the other posting here, the best solution is to use the CSS entry of

style="border:0;"

Native JSON support has been included in PHP since 5.2 in the form of methods json_encode() and json_decode(). You would use the first to output a PHP variable in JSON.

Content is what is passed as children. View is the template of the current component.

The view is initialized before the content and ngAfterViewInit() is therefore called before ngAfterContentInit().

** ngAfterViewInit() is called when the bindings of the children directives (or components) have been checked for the first time. Hence its perfect for accessing and manipulating DOM with Angular 2 components. As @Günter Zöchbauer mentioned before is correct @ViewChild() hence runs fine inside it.

Example:

@Component({
    selector: 'widget-three',
    template: `<input #input1 type="text">`
})
export class WidgetThree{
    @ViewChild('input1') input1;

    constructor(private renderer:Renderer){}

    ngAfterViewInit(){
        this.renderer.invokeElementMethod(
            this.input1.nativeElement,
            'focus',
            []
        )
    }
}

Inspired by other answers this is more correct code that produces integer 0-255 values and appends alpha=255 if you need RGBA:

tuple(np.random.randint(256, size=3)) + (255,)

If you just need RGB:

tuple(np.random.randint(256, size=3))

The first way is easier to maintain. Each declaration is a single statement on a single line, so you can easily add, remove, and reorder the declarations.

With the second way, it is annoying to remove the first or last declaration because they start from the var keyword and finish with the semicolon respectively. Every time you add a new declaration, you have to replace the semicolon in the last old line with a comma.

Use the git commit command without any flags. The configured editor will open (Vim in this case):

To start typing press the INSERT key on your keyboard, then in insert mode create a better commit with description how do you want. For example:

Once you have written all that you need, to returns to git, first you should exit insert mode, for that press ESC. Now close the Vim editor with save changes by typing on the keyboard :wq (w - write, q - quit):

and press ENTER.

On GitHub this commit will looks like this:

As a commit editor you can use VS Code:

git config --global core.editor "code --wait"

From VS Code docs website: VS Code as Git editor

Yes you can pass the model that you have shown using

return RedirectToAction("GetStudent", "Student", student1 );

assuming student1 is an instance of Student

which will generate the following url (assuming your using the default routes and the value of student1 are ID=4 and Name="Amit")

.../Student/GetStudent/4?Name=Amit

Internally the RedirectToAction() method builds a RouteValueDictionary by using the .ToString() value of each property in the model. However, binding will only work if all the properties in the model are simple properties and it fails if any properties are complex objects or collections because the method does not use recursion. If for example, Student contained a property List<string> Subjects, then that property would result in a query string value of

....&Subjects=System.Collections.Generic.List'1[System.String]

and binding would fail and that property would be null

array_reverse() does not alter the source array, but returns a new array. (See array_reverse().) So you either need to store the new array first or just use function within the declaration of your for loop.

<?php 
    $input = array('a', 'b', 'c');
    foreach (array_reverse($input) as $value) {
        echo $value."\n";
    }
?>

The output will be:

c
b
a

So, to address to OP, the code becomes:

<?php
    $j=1;     
    foreach ( array_reverse($skills_nav) as $skill ) {
        $a = '<li><a href="#" data-filter=".'.$skill->slug.'">';
        $a .= $skill->name;                 
        $a .= '</a></li>';
        echo $a;
        echo "\n";
        $j++;
}

Lastly, I'm going to guess that the $j was either a counter used in an initial attempt to get a reverse walk of $skills_nav, or a way to count the $skills_nav array. If the former, it should be removed now that you have the correct solution. If the latter, it can be replaced, outside of the loop, with a $j = count($skills_nav).

this will point to the <ul> selected by .nav-list. You can use delegation instead!

$('.nav-list').on('click', 'li', function() {
    $('.nav-list li.active').removeClass('active');
    $(this).addClass('active');
});

If you are using SPs and if the sps have multiple Select statements (within if conditions) all those selects needs to be handled with unique field names.

The following worked for me. Deleted the folders for numpy and pandas together with their contents completely from the site-packages folder. Check depending on whether you are using python2 or python3. Check the exact path as per your machine.

N.B handle with care "rm -rf" command. If you are not sure of what you are doing, please do it manually using any file explorer of your choice!!

1. rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/pandas*

2. rm -rf ~/anaconda2/envs/myenv/lib/pythonX/site-packages/numpy*

Then i installed clean packages for pandas and numpy as usual with

• pip install numpy
• pip install pandas

One way that I used to do this:

import boto3
s3 = boto3.resource('s3')
bucket=s3.Bucket("bucket_name")
contents = [_.key for _ in bucket.objects.all() if "subfolders/ifany/" in _.key]

In python

arr = [1, 2, 4, 6, 10]
diff_hash = {}
expected_sum = 3
for i in arr:
    if diff_hash.has_key(i):
        print i, diff_hash[i]
    key = expected_sum - i
    diff_hash[key] = i

Use beforeSend:

$.ajax({
         url: "http://localhost/PlatformPortal/Buyers/Account/SignIn",
         data: { signature: authHeader },
         type: "GET",
         beforeSend: function(xhr){xhr.setRequestHeader('X-Test-Header', 'test-value');},
         success: function() { alert('Success!' + authHeader); }
      });

Some googling found this, where people had a discussion about this.

An unsigned char is basically a single byte. So, you would use this if you need one byte of data (for example, maybe you want to use it to set flags on and off to be passed to a function, as is often done in the Windows API).

GridView.Columns.Count will always be 0 when your GridView has its AutoGenerateColumns property set to true (default is true).

You can explicitly declare your columns and set the AutoGenerateColumns property to false, or you can use this in your codebehind:

GridView.Rows[0].Cells.Count

to get the column count once your GridView data has been bound, or this:

protected void GridView_RowDataBound(object sender, GridViewRowEventArgs e)
{
    e.Row.Cells[index].Visible = false;
}

to set a column invisible using your GridView's RowDataBound event.

To check wether html block is existing or not, I'm using this code:

if (typeof($('selector').html()) != 'undefined') {
    // $('selector') is existing
    // your code here
}

cmd /c copy /z src dest

Tensorflow version in Jupyter Notebook:-

!pip list | grep tensorflow

Perhaps your question is in this sense:

If you want to use: $python myscript.py

You don't need that line at all. The system will call python and then python interpreter will run your script.

But if you intend to use: $./myscript.py

Calling it directly like a normal program or bash script, you need write that line to specify to the system which program use to run it, (and also make it executable with chmod 755)
