An enumerated type is basically a data type that lets you describe each member of a type in a more readable and reliable way.

Here is a simple example to explain why:

Assuming you are writing a method that has something to do with seasons:

The int enum pattern

First, you declared some int static constants to represent each season.

public static final int SPRING = 0;
public static final int SUMMER = 1;
public static final int FALL = 2;
public static final int WINTER = 2;

Then, you declared a method to print name of the season into the console.

public void printSeason(int seasonCode) {
    String name = "";
    if (seasonCode == SPRING) {
        name = "Spring";
    }
    else if (seasonCode == SUMMER) {
        name = "Summer";
    }
    else if (seasonCode == FALL) {
        name = "Fall";
    }
    else if (seasonCode == WINTER) {
        name = "Winter";
    }
    System.out.println("It is " + name + " now!");
}

So, after that, you can print a season name like this.

printSeason(SPRING);
printSeason(WINTER);

This is a pretty common (but bad) way to do different things for different types of members in a class. However, since these code involves integers, so you can also call the method like this without any problems.

printSeason(0);
printSeason(1);

or even like this

printSeason(x - y);
printSeason(10000);

The compiler will not complain because these method calls are valid, and your printSeason method can still work.

But something is not right here. What does a season code of 10000 supposed to mean? What if x - y results in a negative number? When your method receives an input that has no meaning and is not supposed to be there, your program knows nothing about it.

You can fix this problem, for example, by adding an additional check.

...
else if (seasonCode == WINTER) {
    name = "Winter";
}
else {
    throw new IllegalArgumentException();
}
System.out.println(name);

Now the program will throw a RunTimeException when the season code is invalid. However, you still need to decide how you are going to handle the exception.

By the way, I am sure you noticed the code of FALL and WINTER are both 2, right?

You should get the idea now. This pattern is brittle. It makes you write condition checks everywhere. If you're making a game, and you want to add an extra season into your imaginary world, this pattern will make you go though all the methods that do things by season, and in most case you will forget some of them.

You might think class inheritance is a good idea for this case. But we just need some of them and no more.

That's when enum comes into play.

Use enum type

In Java, enum types are classes that export one instance for each enumeration constant via a public static final field.

Here you can declare four enumeration constants: SPRING, SUMMER, FALL, WINTER. Each has its own name.

public enum Season {
    SPRING("Spring"), SUMMER("Summer"), FALL("Fall"), WINTER("Winter");

    private String name;

    Season(String name) {
        this.name = name;
    }

    public String getName() {
        return name;
    }
}

Now, back to the method.

public void printSeason(Season season) {
    System.out.println("It is " + season.getName() + " now!");
}

Instead of using int, you can now use Season as input. Instead of a condition check, you can tell Season to give you its name.

This is how you use this method now:

printSeason(Season.SPRING);
printSeason(Season.WINTER);
printSeason(Season.WHATEVER); <-- compile error

You will get a compile-time error when you use an incorrect input, and you're guaranteed to get a non-null singleton reference of Season as long as the program compiles.

When we need an additional season, we simply add another constant in Season and no more.

public enum Season {
    SPRING("Spring"), SUMMER("Summer"), FALL("Fall"), WINTER("Winter"), 
    MYSEASON("My Season");

...

Whenever you need a fixed set of constants, enum can be a good choice (but not always). It's a more readable, more reliable and more powerful solution.

Look into xcopy, which will recursively copy files and subdirectories.

There are examples, 2/3 down the page. Of particular use is:

To copy all the files and subdirectories (including any empty subdirectories) from drive A to drive B, type:

xcopy a: b: /s /e

We had the same problem while working on an Android application for a customer and I managed to "hack" around this restriction.

I took a look at the Android Source code for the WebView class and spotted a updateZoomButtonsEnabled()-method which was working with an ZoomButtonsController-object to enable and disable the zoom controls depending on the current scale of the browser.

I searched for a method to return the ZoomButtonsController-instance and found the getZoomButtonsController()-method, that returned this very instance.

Although the method is declared public, it is not documented in the WebView-documentation and Eclipse couldn't find it either. So, I tried some reflection on that and created my own WebView-subclass to override the onTouchEvent()-method, which triggered the controls.

public class NoZoomControllWebView extends WebView {

    private ZoomButtonsController zoom_controll = null;

    public NoZoomControllWebView(Context context) {
        super(context);
        disableControls();
    }

    public NoZoomControllWebView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        disableControls();
    }

    public NoZoomControllWebView(Context context, AttributeSet attrs) {
        super(context, attrs);
        disableControls();
    }

    /**
     * Disable the controls
     */
    private void disableControls(){
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
            // Use the API 11+ calls to disable the controls
            this.getSettings().setBuiltInZoomControls(true);
            this.getSettings().setDisplayZoomControls(false);
        } else {
            // Use the reflection magic to make it work on earlier APIs
            getControlls();
        }
    }

    /**
     * This is where the magic happens :D
     */
    private void getControlls() {
        try {
            Class webview = Class.forName("android.webkit.WebView");
            Method method = webview.getMethod("getZoomButtonsController");
            zoom_controll = (ZoomButtonsController) method.invoke(this, null);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        super.onTouchEvent(ev);
        if (zoom_controll != null){
            // Hide the controlls AFTER they where made visible by the default implementation.
            zoom_controll.setVisible(false);
        }
        return true;
    }
}

You might want to remove the unnecessary constructors and react on probably on the exceptions.

Although this looks hacky and unreliable, it works back to API Level 4 (Android 1.6).

As @jayellos pointed out in the comments, the private getZoomButtonsController()-method is no longer existing on Android 4.0.4 and later.

However, it doesn't need to. Using conditional execution, we can check if we're on a device with API Level 11+ and use the exposed functionality (see @Yuttadhammo answer) to hide the controls.

I updated the example code above to do exactly that.

For my case handling UIDeviceOrientationDidChangeNotification was not good solution as it is called more frequent and UIDeviceOrientation is not always equal to UIInterfaceOrientation because of (FaceDown, FaceUp).

I handle it using UIApplicationDidChangeStatusBarOrientationNotification:

//To add the notification
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didChangeOrientation:)

//to remove the
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIDeviceOrientationDidChangeNotification object:nil];

 ...

- (void)didChangeOrientation:(NSNotification *)notification
{
    UIInterfaceOrientation orientation = [UIApplication sharedApplication].statusBarOrientation;

    if (UIInterfaceOrientationIsLandscape(orientation)) {
        NSLog(@"Landscape");
    }
    else {
        NSLog(@"Portrait");
    }
}

simple use "accept" and "required" in and avoiding so much typical and unwanted coding.

Sure! Setup:

>>> import pandas as pd
>>> from random import randint
>>> df = pd.DataFrame({'A': [randint(1, 9) for x in range(10)],
                   'B': [randint(1, 9)*10 for x in range(10)],
                   'C': [randint(1, 9)*100 for x in range(10)]})
>>> df
   A   B    C
0  9  40  300
1  9  70  700
2  5  70  900
3  8  80  900
4  7  50  200
5  9  30  900
6  2  80  700
7  2  80  400
8  5  80  300
9  7  70  800

We can apply column operations and get boolean Series objects:

>>> df["B"] > 50
0    False
1     True
2     True
3     True
4    False
5    False
6     True
7     True
8     True
9     True
Name: B
>>> (df["B"] > 50) & (df["C"] == 900)
0    False
1    False
2     True
3     True
4    False
5    False
6    False
7    False
8    False
9    False

[Update, to switch to new-style .loc]:

And then we can use these to index into the object. For read access, you can chain indices:

>>> df["A"][(df["B"] > 50) & (df["C"] == 900)]
2    5
3    8
Name: A, dtype: int64

but you can get yourself into trouble because of the difference between a view and a copy doing this for write access. You can use .loc instead:

>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"]
2    5
3    8
Name: A, dtype: int64
>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"].values
array([5, 8], dtype=int64)
>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"] *= 1000
>>> df
      A   B    C
0     9  40  300
1     9  70  700
2  5000  70  900
3  8000  80  900
4     7  50  200
5     9  30  900
6     2  80  700
7     2  80  400
8     5  80  300
9     7  70  800

Note that I accidentally typed == 900 and not != 900, or ~(df["C"] == 900), but I'm too lazy to fix it. Exercise for the reader. :^)

Each Entry object represents key-value pair. Field next refers to other Entry object if a bucket has more than 1 Entry.

Sometimes it might happen that hashCodes for 2 different objects are the same. In this case 2 objects will be saved in one bucket and will be presented as LinkedList. The entry point is more recently added object. This object refers to other object with next field and so one. Last entry refers to null. When you create HashMap with default constructor

Array is gets created with size 16 and default 0.75 load balance.

You can write the below code:-

create procedure spCreateTable
   as
    begin
       create table testtb(Name varchar(20))
    end

execute it as:-

exec spCreateTable

Recently I was trying to detect the home press button, because I needed it to do the same as the method "onBackPressed()". In order to do this, I had to override the method "onSupportNavigateUp()" like this:

override fun onSupportNavigateUp(): Boolean {
    onBackPressed()
    return true
}

It worked perfectly. =)

Try this:

DateFormat.parse(String)

Based on the answer that @Mukund Kumar gave here's a version that passes the event argument to the anonymous function:

<a href="#" onClick="(function(e){
    console.log(e);
    alert('Hey i am calling');
    return false;
})(arguments[0]);return false;">click here</a>

This will work:

select * into DestinationDatabase.dbo.[TableName1] from (
Select * from sourceDatabase.dbo.[TableName1])Temp

Use index=False.

df.to_csv('your.csv', index=False)

I had a somehow similar problem working with AFNetworking from a Swift codebase so I'm just leaving this here in the remote case someone is as unlucky as me having to work in such a setup. If you are, I feel you buddy, stay strong!

The operation was failing due to "unacceptable content-type", despite me actually setting the acceptableContentTypes with a Set containing the content type value in question.

The solution for me was to tweak the Swift code to be more Objective-C friendly, I guess:

serializer.acceptableContentTypes = NSSet(array: ["application/xml", "text/xml", "text/plain"]) as Set<NSObject>

<graphics.h> is not a standard header. Most commonly it refers to the header for Borland's BGI API for DOS and is antiquated at best.

However it is nicely simple; there is a Win32 implementation of the BGI interface called WinBGIm. It is implemented using Win32 GDI calls - the lowest level Windows graphics interface. As it is provided as source code, it is perhaps a simple way of understanding how GDI works.

WinBGIm however is by no means cross-platform. If all you want are simple graphics primitives, most of the higher level GUI libraries such as wxWidgets and Qt support that too. There are simpler libraries suggested in the possible duplicate answers mentioned in the comments.

If you want to use only text while making swipe actions then you can use iOS default swipe actions but if you want image and text, then you have to customize it. I have found a great tutorial and sample that can resolve this problem.

Try out this repository to get the custom swipe cell. You can add multiple option here.

The clear way to do this is as follows if you do not mind writing the file again

with open("a.txt", 'r+') as fp:
    lines = fp.readlines()     # lines is list of line, each element '...\n'
    lines.insert(0, one_line)  # you can use any index if you know the line index
    fp.seek(0)                 # file pointer locates at the beginning to write the whole file again
    fp.writelines(lines)       # write whole lists again to the same file

Note that this is not in-place replacement. It's writing a file again.

In summary, you read a file and save it to a list and modify the list and write the list again to a new file with the same filename.

A PHP array or object or other complex data structure cannot be transported or stored or otherwise used outside of a running PHP script. If you want to persist such a complex data structure beyond a single run of a script, you need to serialize it. That just means to put the structure into a "lower common denominator" that can be handled by things other than PHP, like databases, text files, sockets. The standard PHP function serialize is just a format to express such a thing, it serializes a data structure into a string representation that's unique to PHP and can be reversed into a PHP object using unserialize. There are many other formats though, like JSON or XML.

Take for example this common problem:

How do I pass a PHP array to Javascript?

PHP and Javascript can only communicate via strings. You can pass the string "foo" very easily to Javascript. You can pass the number 1 very easily to Javascript. You can pass the boolean values true and false easily to Javascript. But how do you pass this array to Javascript?

Array ( [1] => elem 1 [2] => elem 2 [3] => elem 3 ) 

The answer is serialization. In case of PHP/Javascript, JSON is actually the better serialization format:

{ 1 : 'elem 1', 2 : 'elem 2', 3 : 'elem 3' }

Javascript can easily reverse this into an actual Javascript array.

This is just as valid a representation of the same data structure though:

a:3:{i:1;s:6:"elem 1";i:2;s:6:"elem 2";i:3;s:7:" elem 3";}

But pretty much only PHP uses it, there's little support for this format anywhere else.
This is very common and well supported as well though:

<array>
    <element key='1'>elem 1</element>
    <element key='2'>elem 2</element>
    <element key='3'>elem 3</element>
</array>

There are many situations where you need to pass complex data structures around as strings. Serialization, representing arbitrary data structures as strings, solves how to do this.

@Url.Action("Survey", "Applications", new { applicationid = @Model.ApplicationID }, protocol: Request.Url.Scheme)

It is worth to note that it's possible to add Q expressions.

For example:

from django.db.models import Q

query = Q(first_name='mark')
query.add(Q(email='[email protected]'), Q.OR)
query.add(Q(last_name='doe'), Q.AND)

queryset = User.objects.filter(query)

This ends up with a query like :

(first_name = 'mark' or email = '[email protected]') and last_name = 'doe'

This way there is no need to deal with or operators, reduce's etc.

Surprised that nobody mentioned that zoom: 1; is useful for IE6-7, to solve most IE-only bugs by triggering hasLayout.

http://forums.iis.net/t/1187650.aspx has the answer. Setting the iis authentication to appliction pool identity will resolve this.

In IIS Authentication, Anonymous Authentication was set to "Specific User". When I changed it to Application Pool, I can access the site.

To set, click on your website in IIS and double-click "Authentication". Right-click on "Anonymous Authentication" and click "Edit..." option. Switch from "Specific User" to "Application pool identity". Now you should be able to set file and folder permissions using the IIS AppPool\{Your App Pool Name}.

An alternative way to do that, is to enter a LaTeX environment within the notebook and change color from there (which is great if you are more fluent in LaTeX than in HTML). Example:

$\color{red}{\text{ciao}}$

would display ciao in red.

I had the same error and it occured when changing the mysql/data folder to another folder.
I just copied all folders inside mysql/data folder to a new location except for two files. Those are ib_logfile0 and ib_logfile1; those are automatically created when starting the MySQL server. That worked for me.

I have found that the simplest way to do this is to set onClick for each button in the xml

<Button
android:id="@+id/vrHelp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/ic_menu_help"
android:onClick="helpB" />

and then you can do a switch case like this

  public void helpB(View v) {
    Button clickedButton = (Button) v;
    switch (clickedButton.getId()) {
      case R.id.vrHelp:
        dosomething...
        break;

      case R.id.coHelp:
        dosomething...
        break;

      case R.id.ksHelp:
        dosomething...
        break;

      case R.id.uHelp:
        dosomething...
        break;

      case R.id.pHelp:
        dosomething...
        break;
    }
  }

since your over div doesn't have a positioning, the z-index doesn't know where and how to position it (and with respect to what?). Just change your over div's position to relative, so there is no side effects on that div and then the under div will obey to your will.

here is your example on jsfiddle: Fiddle

may you try

Here's the solution you're looking for:

>>> foos = [1.0, 2.0, 3.0, 4.0, 5.0]
>>> bars = [1, 2, 3]
>>> [(x, bars) for x in foos]
[(1.0, [1, 2, 3]), (2.0, [1, 2, 3]), (3.0, [1, 2, 3]), (4.0, [1, 2, 3]), (5.0, [
1, 2, 3])]

I'd recommend using a list comprehension (the [(x, bars) for x in foos] part) over using map as it avoids the overhead of a function call on every iteration (which can be very significant). If you're just going to use it in a for loop, you'll get better speeds by using a generator comprehension:

>>> y = ((x, bars) for x in foos)
>>> for z in y:
...     print z
...
(1.0, [1, 2, 3])
(2.0, [1, 2, 3])
(3.0, [1, 2, 3])
(4.0, [1, 2, 3])
(5.0, [1, 2, 3])

The difference is that the generator comprehension is lazily loaded.

UPDATE In response to this comment:

Of course you know, that you don't copy bars, all entries are the same bars list. So if you modify any one of them (including original bars), you modify all of them.

I suppose this is a valid point. There are two solutions to this that I can think of. The most efficient is probably something like this:

tbars = tuple(bars)
[(x, tbars) for x in foos]

Since tuples are immutable, this will prevent bars from being modified through the results of this list comprehension (or generator comprehension if you go that route). If you really need to modify each and every one of the results, you can do this:

from copy import copy
[(x, copy(bars)) for x in foos]

However, this can be a bit expensive both in terms of memory usage and in speed, so I'd recommend against it unless you really need to add to each one of them.

pip uninstall PIL

as other suggested yielded for me

WARNING: Skipping PIL as it is not installed.

But I am not sure about the consequences of removing that library so I will edit this post if I ever get into a problem because of that.

Excel has no way of gathering that attribute with it's built-in functions. If you're willing to use some VB, all your color-related questions are answered here:

http://www.cpearson.com/excel/colors.aspx

Example form the site:

The SumColor function is a color-based analog of both the SUM and SUMIF function. It allows you to specify separate ranges for the range whose color indexes are to be examined and the range of cells whose values are to be summed. If these two ranges are the same, the function sums the cells whose color matches the specified value. For example, the following formula sums the values in B11:B17 whose fill color is red.

=SUMCOLOR(B11:B17,B11:B17,3,FALSE)

Finding the root path of an electron app could get tricky. Because the root path is different for the main process and renderer under different conditions such as production, development and packaged conditions.

I have written a npm package electron-root-path to capture the root path of an electron app.

$ npm install electron-root-path

or 

$ yarn add electron-root-path


// Import ES6 way
import { rootPath } from 'electron-root-path';

// Import ES2015 way
const rootPath = require('electron-root-path').rootPath;

// e.g:
// read a file in the root
const location = path.join(rootPath, 'package.json');
const pkgInfo = fs.readFileSync(location, { encoding: 'utf8' });

TYPE_SYSTEM_OVERLAY This constant was deprecated in since API level 26. Use TYPE_APPLICATION_OVERLAY instead. or **for users below and above android 8

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
    LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}

Something a bit more functional (easy to use anywhere):

function strip_carriage_returns($string)
{
    return str_replace(array("\n\r", "\n", "\r"), '', $string);
}

Using PHP_EOL as the search replacement parameter is also a good idea! Kudos.

In order to move a View anywhere on the screen, I would recommend placing it in a full screen layout. By doing so, you won't have to worry about clippings or relative coordinates.

You can try this sample code:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" android:id="@+id/rootLayout">

    <Button
        android:id="@+id/btn1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="MOVE" android:layout_centerHorizontal="true"/>

    <ImageView
        android:id="@+id/img1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="10dip"/>
    <ImageView
        android:id="@+id/img2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_centerVertical="true" android:layout_alignParentRight="true"/>
    <ImageView
        android:id="@+id/img3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_alignParentBottom="true" android:layout_marginBottom="100dip"/>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" android:clipChildren="false" android:clipToPadding="false">

        <ImageView
            android:id="@+id/img4"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/ic_launcher" android:layout_marginLeft="60dip" android:layout_marginTop="150dip"/>
    </LinearLayout>

</RelativeLayout>

Your activity

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    ((Button) findViewById( R.id.btn1 )).setOnClickListener( new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {
            ImageView img = (ImageView) findViewById( R.id.img1 );              
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img2 );
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img3 );                
            moveViewToScreenCenter( img );
            img = (ImageView) findViewById( R.id.img4 );
            moveViewToScreenCenter( img );
        }
    });
}

private void moveViewToScreenCenter( View view )
{
    RelativeLayout root = (RelativeLayout) findViewById( R.id.rootLayout );
    DisplayMetrics dm = new DisplayMetrics();
    this.getWindowManager().getDefaultDisplay().getMetrics( dm );
    int statusBarOffset = dm.heightPixels - root.getMeasuredHeight();

    int originalPos[] = new int[2];
    view.getLocationOnScreen( originalPos );

    int xDest = dm.widthPixels/2;
    xDest -= (view.getMeasuredWidth()/2);
    int yDest = dm.heightPixels/2 - (view.getMeasuredHeight()/2) - statusBarOffset;

    TranslateAnimation anim = new TranslateAnimation( 0, xDest - originalPos[0] , 0, yDest - originalPos[1] );
    anim.setDuration(1000);
    anim.setFillAfter( true );
    view.startAnimation(anim);
}

The method moveViewToScreenCenter gets the View's absolute coordinates and calculates how much distance has to move from its current position to reach the center of the screen. The statusBarOffset variable measures the status bar height.

I hope you can keep going with this example. Remember that after the animation your view's position is still the initial one. If you tap the MOVE button again and again the same movement will repeat. If you want to change your view's position do it after the animation is finished.

What operating system are you using? I use Linux Mint. In my case it turned out to be a symbolic link issue. Every time I tried to create the project with the symlink path, it would give me that error. Creating the project elsewhere, and then migrating it to the symlinked directory solved it for me.

In my opinion, a dynamic PL/SQL block is somewhat obscure. While is very flexible, is also hard to tune, hard to debug and hard to figure out what's up. My vote goes to your first option,

EXECUTE IMMEDIATE v_query_str INTO v_num_of_employees USING p_job;

Both uses bind variables, but first, for me, is more redeable and tuneable than @jonearles option.

A Schema is a collection of database objects which includes logical structures too. It has the name of the user who owns it. A database can have any number of Schema's. One table from a database can appear in two different schemas of same name. A user can view any schema for which they have been assigned select privilege.

you can use clientscript. MSDN : Clientscript

String scriptText = 
        "alert('sdsd');";
    ClientScript.RegisterOnSubmitStatement(this.GetType(), 
        "ConfirmSubmit", scriptText);

try this

ClientScript.RegisterStartupScript(this.GetType(), "JSScript", scriptText); 



ClientScript.RegisterClientScriptBlock(this.GetType(), "alert", scriptText); //use this 

Just another way to retrieve the same data using INFORMATION_SCHEMA

The information schema views included in SQL Server comply with the ISO standard definition for the INFORMATION_SCHEMA.

sqlauthority way

SELECT
K_Table = FK.TABLE_NAME,
FK_Column = CU.COLUMN_NAME,
PK_Table = PK.TABLE_NAME,
PK_Column = PT.COLUMN_NAME,
Constraint_Name = C.CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS C
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS FK ON C.CONSTRAINT_NAME = FK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS PK ON C.UNIQUE_CONSTRAINT_NAME = PK.CONSTRAINT_NAME
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE CU ON C.CONSTRAINT_NAME = CU.CONSTRAINT_NAME
INNER JOIN (
SELECT i1.TABLE_NAME, i2.COLUMN_NAME
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS i1
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE i2 ON i1.CONSTRAINT_NAME = i2.CONSTRAINT_NAME
WHERE i1.CONSTRAINT_TYPE = 'PRIMARY KEY'
) PT ON PT.TABLE_NAME = PK.TABLE_NAME
---- optional:
ORDER BY
1,2,3,4
WHERE PK.TABLE_NAME='something'WHERE FK.TABLE_NAME='something'
WHERE PK.TABLE_NAME IN ('one_thing', 'another')
WHERE FK.TABLE_NAME IN ('one_thing', 'another')

Access can always use the Excel procedure as long as the project has the Microsoft Excel XX.X object reference included:

Call Excel.Application.Wait(DateAdd("s",10,Now()))

Alternately, if you are using a Macro Enabled workbook:

Add any control at all from the Developer -> Insert (Probably a button)

When it asks what Macro to assign, choose New. For the code for the generated module enter something like:

Thisworkbook.Sheets("Sheet Name").Activate

However, if you are not using Macros in your work book. Ooo's approach is definitely surperior as hyperlinks will work with no need to trust the document.

I figured out that this behaves like a mousedown event:

button:active:hover {}

If you have less than 4 rows, you can use the head function ( head(data, 4) or head(data, n=4)) and it works like a charm. But, assume we have the following dataset with 15 rows

>data <- data <- read.csv("./data.csv", sep = ";", header=TRUE)

>data
 LungCap Age Height Smoke Gender Caesarean
1    6.475   6   62.1    no   male        no
2   10.125  18   74.7   yes female        no
3    9.550  16   69.7    no female       yes
4   11.125  14   71.0    no   male        no
5    4.800   5   56.9    no   male        no
6    6.225  11   58.7    no female        no
7    4.950   8   63.3    no   male       yes

9    8.875  15   70.5    no   male        no
10   6.800  11   59.2    no   male        no

14   6.120  15   59.6    no   male        no
15   6.130  16   59.7    no   male        no

Let's say, you want to select the first 10 rows. The easiest way to do it would be data[1:10, ].

> data[1:10,]
   LungCap Age Height Smoke Gender Caesarean

10   6.800  11   59.2    no   male        no

However, let's say you try to retrieve the first 19 rows and see the what happens - you will have missing values

http://docs.jquery.com/Events/unload#fn

cp -r /home/server/folder/test /home/server/

using return false in an onclick event stops the browser from processing the rest of the execution stack, which includes following the link in the href attribute.

In other words, adding return false stops the href from working. In your example, this is exactly what you want.

In buttons, it's not necessary because onclick is all it will ever execute -- there is no href to process and go to.

The answer depends on the presence of other shapes, level of noise if any and invariance you want to provide for (e.g. rotation, scaling, etc). These requirements will define not only the algorithm but also required pre-procesing stages to extract features.

Template matching that was suggested above works well when shapes aren't rotated or scaled and when there are no similar shapes around; in other words, it finds a best translation in the image where template is located:

double minVal, maxVal;
Point minLoc, maxLoc;
Mat image, template, result; // template is your shape
matchTemplate(image, template, result, CV_TM_CCOEFF_NORMED);
minMaxLoc(result, &minVal, &maxVal, &minLoc, &maxLoc); // maxLoc is answer

Geometric hashing is a good method to get invariance in terms of rotation and scaling; this method would require extraction of some contour points.

Generalized Hough transform can take care of invariance, noise and would have minimal pre-processing but it is a bit harder to implement than other methods. OpenCV has such transforms for lines and circles.

In the case when number of shapes is limited calculating moments or counting convex hull vertices may be the easiest solution: openCV structural analysis

Simply put, the ++ and -- operators don't exist in Python because they wouldn't be operators, they would have to be statements. All namespace modification in Python is a statement, for simplicity and consistency. That's one of the design decisions. And because integers are immutable, the only way to 'change' a variable is by reassigning it.

Fortunately we have wonderful tools for the use-cases of ++ and -- in other languages, like enumerate() and itertools.count().

I fixed the issue by changing the code to

@Basic(optional = false)
@Column(name = "LastTouched", insertable = false, updatable = false)
@Temporal(TemporalType.TIMESTAMP)
private Date lastTouched;

So the timestamp column is ignored when generating SQL inserts. Not sure if this is the best way to go about this. Feedback is welcome.

Then apart from these 4, we have

foldByKey which is same as reduceByKey but with a user defined Zero Value.

AggregateByKey takes 3 parameters as input and uses 2 functions for merging(one for merging on same partitions and another to merge values across partition. The first parameter is ZeroValue)

whereas

ReduceBykey takes 1 parameter only which is a function for merging.

CombineByKey takes 3 parameter and all 3 are functions. Similar to aggregateBykey except it can have a function for ZeroValue.

GroupByKey takes no parameter and groups everything. Also, it is an overhead for data transfer across partitions.

this will work

<h:outputText value="&#160;" />

DOMDocument is a great choice. It's a module specifically designed for creating and manipulating XML documents. You can create a document from scratch, or open existing documents (or strings) and navigate and modify their structures.

$xml = new DOMDocument();
$xml_album = $xml->createElement("Album");
$xml_track = $xml->createElement("Track");
$xml_album->appendChild( $xml_track );
$xml->appendChild( $xml_album );

$xml->save("/tmp/test.xml");

To re-open and write:

$xml = new DOMDocument();
$xml->load('/tmp/test.xml');
$nodes = $xml->getElementsByTagName('Album') ;
if ($nodes->length > 0) {
   //insert some stuff using appendChild()
}

//re-save
$xml->save("/tmp/test.xml");

For people like me, linq addicts, and based on svick's answer, here a linq approach:

using System.Linq;
//...
//make it linq iterable. 
var obj_linq = Response.Cast<KeyValuePair<string, JToken>>();

Now you can make linq expressions like:

JToken x = obj_linq
          .Where( d => d.Key == "my_key")
          .Select(v => v)
          .FirstOrDefault()
          .Value;
string y = ((JValue)x).Value;

Or just:

var y = obj_linq
       .Where(d => d.Key == "my_key")
       .Select(v => ((JValue)v.Value).Value)
       .FirstOrDefault();

Or this one to iterate over all data:

obj_linq.ToList().ForEach( x => { do stuff } ); 

The ClientRepository should be annotated with @Repository tag. With your current configuration Spring will not scan the class and have knowledge about it. At the moment of booting and wiring will not find the ClientRepository class.

EDIT If adding the @Repository tag doesn't help, then I think that the problem might be now with the ClientService and ClientServiceImpl.

Try to annotate the ClientService (interface) with @Service. As you should only have a single implementation for your service, you don't need to specify a name with the optional parameter @Service("clientService"). Spring will autogenerate it based on the interface' name.

Also, as Bruno mentioned, the @Qualifier is not needed in the ClientController as you only have a single implementation for the service.

ClientService.java

@Service
public interface ClientService {

    void addClient(Client client);
}

ClientServiceImpl.java (option 1)

@Service
public class ClientServiceImpl implements ClientService{

    private ClientRepository clientRepository;

    @Autowired
    public void setClientRepository(ClientRepository clientRepository){
        this.clientRepository=clientRepository;
    }

    @Transactional
    public void addClient(Client client){
        clientRepository.saveAndFlush(client);
    }
}

ClientServiceImpl.java (option 2/preferred)

@Service
public class ClientServiceImpl implements ClientService{

    @Autowired
    private ClientRepository clientRepository;

    @Transactional
    public void addClient(Client client){
        clientRepository.saveAndFlush(client);
    }
}

ClientController.java

@Controller
public class ClientController {
    private ClientService clientService;

    @Autowired
    //@Qualifier("clientService")
    public void setClientService(ClientService clientService){
        this.clientService=clientService;
    }

    @RequestMapping(value = "registration", method = RequestMethod.GET)
    public String reg(Model model){
        model.addAttribute("client", new Client());
        return "registration";
    }

    @RequestMapping(value = "registration/add", method = RequestMethod.POST)
    public String addUser(@ModelAttribute Client client){
        this.clientService.addClient(client);
    return "home";
    }
}

getElementsByClassName is a function on the DOM Document. It is neither a jQuery nor a jqLite function.

Don't add the period before the class name when using it:

var result = document.getElementsByClassName("multi-files");

Wrap it in jqLite (or jQuery if jQuery is loaded before Angular):

var wrappedResult = angular.element(result);

If you want to select from the element in a directive's link function you need to access the DOM reference instead of the the jqLite reference - element[0] instead of element:

link: function (scope, element, attrs) {

  var elementResult = element[0].getElementsByClassName('multi-files');
}

Alternatively you can use the document.querySelector function (need the period here if selecting by class):

var queryResult = element[0].querySelector('.multi-files');
var wrappedQueryResult = angular.element(queryResult);

The reload happens during the next layout pass, which normally happens when you return control to the run loop (after, say, your button action or whatever returns).

So one way to run something after the table view reloads is simply to force the table view to perform layout immediately:

[self.tableView reloadData];
[self.tableView layoutIfNeeded];
 NSIndexPath* indexPath = [NSIndexPath indexPathForRow: ([self.tableView numberOfRowsInSection:([self.tableView numberOfSections]-1)]-1) inSection: ([self.tableView numberOfSections]-1)];
[self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];

Another way is to schedule your after-layout code to run later using dispatch_async:

[self.tableView reloadData];

dispatch_async(dispatch_get_main_queue(), ^{
     NSIndexPath* indexPath = [NSIndexPath indexPathForRow: ([self.tableView numberOfRowsInSection:([self.tableView numberOfSections]-1)]-1) inSection:([self.tableView numberOfSections]-1)];

    [self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:YES];
});

UPDATE

Upon further investigation, I find that the table view sends tableView:numberOfSections: and tableView:numberOfRowsInSection: to its data source before returning from reloadData. If the delegate implements tableView:heightForRowAtIndexPath:, the table view also sends that (for each row) before returning from reloadData.

However, the table view does not send tableView:cellForRowAtIndexPath: or tableView:headerViewForSection until the layout phase, which happens by default when you return control to the run loop.

I also find that in a tiny test program, the code in your question properly scrolls to the bottom of the table view, without me doing anything special (like sending layoutIfNeeded or using dispatch_async).

Java passes by value; there's no out parameter like in C#.

You can either use return, or mutate an object passed as a reference (by value).

Related questions

• Does Java have something like C#'s ref and out keywords? ? (NO!)
• Is Java pass by reference? (NO!)

    static String fReturn() {
        return "Hello!";
    }
    static void fArgNoWorkie(String s) {
        s = "What am I doing???"; // Doesn't "work"! Java passes by value!
    }
    static void fMutate(StringBuilder sb) {
        sb.append("Here you go!");
    }
    public static void main(String[] args) {
        String s = null;

        s = fReturn();
        System.out.println(s); // prints "Hello!"

        fArgNoWorkie(s);
        System.out.println(s); // prints "Hello!"

        StringBuilder sb = new StringBuilder();
        fMutate(sb);
        s = sb.toString();
        System.out.println(s); // prints "Here you go!"
    }

}

As for the code that OP needs help with, here's a typical solution of using a special value (usually null for reference types) to indicate success/failure:

Instead of:

String oPerson= null;
if (CheckAddress("5556", oPerson)) {
   print(oPerson); // DOESN'T "WORK"! Java passes by value; String is immutable!
}

private boolean CheckAddress(String iAddress, String oPerson) {
   // on search succeeded:
   oPerson = something; // DOESN'T "WORK"!
   return true;
   :
   // on search failed:
   return false;
}

Use a String return type instead, with null to indicate failure.

String person = checkAddress("5556");
if (person != null) {
   print(person);
}

private String checkAddress(String address) {
   // on search succeeded:
   return something;
   :
   // on search failed:
   return null;
}

This is how java.io.BufferedReader.readLine() works, for example: it returns instanceof String (perhaps an empty string!), until it returns null to indicate end of "search".

This is not limited to a reference type return value, of course. The key is that there has to be some special value(s) that is never a valid value, and you use that value for special purposes.

Another classic example is String.indexOf: it returns -1 to indicate search failure.

Note: because Java doesn't have a concept of "input" and "output" parameters, using the i- and o- prefix (e.g. iAddress, oPerson) is unnecessary and unidiomatic.

A more general solution

If you need to return several values, usually they're related in some way (e.g. x and y coordinates of a single Point). The best solution would be to encapsulate these values together. People have used an Object[] or a List<Object>, or a generic Pair<T1,T2>, but really, your own type would be best.

For this problem, I recommend an immutable SearchResult type like this to encapsulate the boolean and String search results:

public class SearchResult {
   public final String name;
   public final boolean isFound;

   public SearchResult(String name, boolean isFound) {
      this.name = name;
      this.isFound = isFound;
   }
}

Then in your search function, you do the following:

private SearchResult checkAddress(String address) {
  // on address search succeed
  return new SearchResult(foundName, true);
  :
  // on address search failed
  return new SearchResult(null, false);
}

And then you use it like this:

SearchResult sr = checkAddress("5556");
if (sr.isFound) {
  String name = sr.name;
  //...
}

If you want, you can (and probably should) make the final immutable fields non-public, and use public getters instead.

That is the textarea's job - for multiline text input. The input won't do it; it wasn't designed to do it.

So use a textarea. Besides their visual differences, they are accessed via JavaScript the same way (use value property).

You can prevent newlines being entered via the input event and simply using a replace(/\n/g, '').

You can also simply create ONLY a UIView in Interface builder and drag & drop the ImageView and UILabel (to make it look like your desired header) and then use that.

Once your UIView looks like the way you want it too, you can programmatically initialize it from the XIB and add to your UITableView. In other words, you dont have to design the ENTIRE table in IB. Just the headerView (this way the header view can be reused in other tables as well)

For example I have a custom UIView for one of my table headers. The view is managed by a xib file called "CustomHeaderView" and it is loaded into the table header using the following code in my UITableViewController subclass:

-(UIView *) customHeaderView {
    if (!customHeaderView) {
        [[NSBundle mainBundle] loadNibNamed:@"CustomHeaderView" owner:self options:nil];
    }

    return customHeaderView;
}

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Set the CustomerHeaderView as the tables header view 
    self.tableView.tableHeaderView = self.customHeaderView;
}

You can also manually tag the column with a contrasts attribute, which seems to be respected by the regression functions:

contrasts(df$factorcol) <- contr.treatment(levels(df$factorcol),
   base=which(levels(df$factorcol) == 'RefLevel'))

In scikit-learn 0.22.0 you can pass mean_squared_error() the argument squared=False to return the RMSE.

from sklearn.metrics import mean_squared_error

mean_squared_error(y_actual, y_predicted, squared=False)

I'm looking for a better LRU cache using Java code. Is it possible for you to share your Java LRU cache code using LinkedHashMap and Collections#synchronizedMap? Currently I'm using LRUMap implements Map and the code works fine, but I'm getting ArrayIndexOutofBoundException on load testing using 500 users on the below method. The method moves the recent object to front of the queue.

private void moveToFront(int index) {
        if (listHead != index) {
            int thisNext = nextElement[index];
            int thisPrev = prevElement[index];
            nextElement[thisPrev] = thisNext;
            if (thisNext >= 0) {
                prevElement[thisNext] = thisPrev;
            } else {
                listTail = thisPrev;
            }
            //old listHead and new listHead say new is 1 and old was 0 then prev[1]= 1 is the head now so no previ so -1
            // prev[0 old head] = new head right ; next[new head] = old head
            prevElement[index] = -1;
            nextElement[index] = listHead;
            prevElement[listHead] = index;
            listHead = index;
        }
    }

get(Object key) and put(Object key, Object value) method calls the above moveToFront method.

Always use library. Never use require.

In a nutshell, this is because, when using require, your code might yield different, erroneous results, without signalling an error. This is rare but not hypothetical! Consider this code, which yields different results depending on whether {dplyr} can be loaded:

require(dplyr)

x = data.frame(y = seq(100))
y = 1
filter(x, y == 1)

This can lead to subtly wrong results. Using library instead of require throws an error here, signalling clearly that something is wrong. This is good.

It also makes debugging all other failures more difficult: If you require a package at the start of your script and use its exports in line 500, you’ll get an error message “object ‘foo’ not found” in line 500, rather than an error “there is no package called ‘bla’”.

The only acceptable use case of require is when its return value is immediately checked, as some of the other answers show. This is a fairly common pattern but even in these cases it is better (and recommended, see below) to instead separate the existence check and the loading of the package. That is: use requireNamespace instead of require in these cases.

More technically, require actually calls library internally (if the package wasn’t already attached — require thus performs a redundant check, because library also checks whether the package was already loaded). Here’s a simplified implementation of require to illustrate what it does:

require = function (package) {
    already_attached = paste('package:', package) %in% search()
    if (already_attached) return(TRUE)
    maybe_error = try(library(package, character.only = TRUE)) 
    success = ! inherits(maybe_error, 'try-error')
    if (! success) cat("Failed")
    success
}

Experienced R developers agree:

Yihui Xie, author of {knitr}, {bookdown} and many other packages says:

Ladies and gentlemen, I've said this before: require() is the wrong way to load an R package; use library() instead

Hadley Wickham, author of more popular R packages than anybody else, says

Use library(x) in data analysis scripts. […] You never need to use require() (requireNamespace() is almost always better)

I use a combination of the approach used in answer by Markus T and a simple helper implementation of ImportBeanDefinitionRegistrar that looks for a custom annotation (@MockedBeans) in which one can specify which classes are to be mocked. I believe that this approach results in a concise unit test with some of the boilerplate code related to mocking removed.

Here's how a sample unit test looks with that approach:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader=AnnotationConfigContextLoader.class)
public class ExampleServiceIntegrationTest {

    //our service under test, with mocked dependencies injected
    @Autowired
    ExampleService exampleService;

    //we can autowire mocked beans if we need to used them in tests
    @Autowired
    DependencyBeanA dependencyBeanA;

    @Test
    public void testSomeMethod() {
        ...
        exampleService.someMethod();
        ...
        verify(dependencyBeanA, times(1)).someDependencyMethod();
    }

    /**
     * Inner class configuration object for this test. Spring will read it thanks to
     * @ContextConfiguration(loader=AnnotationConfigContextLoader.class) annotation on the test class.
     */
    @Configuration
    @Import(TestAppConfig.class) //TestAppConfig may contain some common integration testing configuration
    @MockedBeans({DependencyBeanA.class, DependencyBeanB.class, AnotherDependency.class}) //Beans to be mocked
    static class ContextConfiguration {

        @Bean
        public ExampleService exampleService() {
            return new ExampleService(); //our service under test
        }
    }
}

To make this happen you need to define two simple helper classes - custom annotation (@MockedBeans) and a custom ImportBeanDefinitionRegistrar implementation. @MockedBeans annotation definition needs to be annotated with @Import(CustomImportBeanDefinitionRegistrar.class) and the ImportBeanDefinitionRgistrar needs to add mocked beans definitions to the configuration in it's registerBeanDefinitions method.

If you like the approach you can find sample implementations on my blogpost.

I am using Sublime Text 3 with a Flask project. I fixed the error using View > Indentation > Tab Width: 4 after unselected Indent Using Spaces

This depends on the CPU you're using, on the OS, on what other processes are doing, on what Java release you're using, and other factors. I've seen a Windows server have > 6500 Threads before bringing the machine down. Most of the threads were not doing anything, of course. Once the machine hit around 6500 Threads (in Java), the whole machine started to have problems and become unstable.

My experience shows that Java (recent versions) can happily consume as many Threads as the computer itself can host without problems.

Of course, you have to have enough RAM and you have to have started Java with enough memory to do everything that the Threads are doing and to have a stack for each Thread. Any machine with a modern CPU (most recent couple generations of AMD or Intel) and with 1 - 2 Gig of memory (depending on OS) can easily support a JVM with thousands of Threads.

If you need a more specific answer than this, your best bet is to profile.

if it is coming from server as object you can do 

this.service.subscribe(data:any) keep any type on data it will solve the issue

bool pointInRectangle(Point A, Point B, Point C, Point D, Point m ) {
    Point AB = vect2d(A, B);  float C1 = -1 * (AB.y*A.x + AB.x*A.y); float  D1 = (AB.y*m.x + AB.x*m.y) + C1;
    Point AD = vect2d(A, D);  float C2 = -1 * (AD.y*A.x + AD.x*A.y); float D2 = (AD.y*m.x + AD.x*m.y) + C2;
    Point BC = vect2d(B, C);  float C3 = -1 * (BC.y*B.x + BC.x*B.y); float D3 = (BC.y*m.x + BC.x*m.y) + C3;
    Point CD = vect2d(C, D);  float C4 = -1 * (CD.y*C.x + CD.x*C.y); float D4 = (CD.y*m.x + CD.x*m.y) + C4;
    return     0 >= D1 && 0 >= D4 && 0 <= D2 && 0 >= D3;}

Justin's answer is probably the way to go, although in some applications it might make sense to consider a particular search as a resource in its own right, such as if you want to support named saved searches:

/search/{searchQuery}

or

/search/{savedSearchName}

In my opinion that is easiest and fastest way:

$ npm -v

4.2.0

$ npm install -g npm@latest-3

...

$ npm -v

3.10.10

//Page load starts here

var json = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(new
{
    api_key = "my key",
    action = "categories",
    store_id = "my store"
});

var json2 = "{\"api_key\":\"my key\",\"action\":\"categories\",\"store_id\":\"my store\",\"user\" : {\"id\" : 12345,\"screen_name\" : \"twitpicuser\"}}";
var list = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<FooBar>(json);
var list2 = new System.Web.Script.Serialization.JavaScriptSerializer().Deserialize<FooBar>(json2);

string a = list2.action;
var b = list2.user;
string c = b.screen_name;

//Page load ends here

public class FooBar
{
    public string api_key { get; set; }
    public string action { get; set; }
    public string store_id { get; set; }
    public User user { get; set; }
}

public class User
{
    public int id { get; set; }
    public string screen_name { get; set; }
}

If you are using Java 8 then you can do this easier with CompletableFuture and CompletableFuture.allOf, which applies the callback only after all supplied CompletableFutures are done.

// Waits for *all* futures to complete and returns a list of results.
// If *any* future completes exceptionally then the resulting future will also complete exceptionally.

public static <T> CompletableFuture<List<T>> all(List<CompletableFuture<T>> futures) {
    CompletableFuture[] cfs = futures.toArray(new CompletableFuture[futures.size()]);

    return CompletableFuture.allOf(cfs)
            .thenApply(ignored -> futures.stream()
                                    .map(CompletableFuture::join)
                                    .collect(Collectors.toList())
            );
}

Sometimes when we do these steps:

 alter table my_table drop constraint my_pk; 
 alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

The last statement fails with

ORA-00955 "name is already used by an existing object"

Oracle usually creates an unique index with the same name my_pk. In such a case you can drop the unique index or rename it based on whether the constraint is still relevant.

You can combine the dropping of primary key constraint and unique index into a single sql statement:

alter table my_table drop constraint my_pk drop index; 

check this: ORA-00955 "name is already used by an existing object"

If you are using Netbeans, try to hit the Clean and Build button, let it do the thing and try again. Worked for me!

After starting intent you can use this code :

Intent intent = new Intent(Activity1.this, Activity2.class);
overridePendingTransition(0, 0);
intent.setFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
startActivity(intent);

If used, intent will work with no animations or transitions

Please try this

SET HTTP_PROXY=<proxy_name>

Then try that command.It will work

Call

There are three unique situations:

• 4 numbers, e.g. Margin="a,b,c,d".
• 2 numbers, e.g. Margin="a,b".
• 1 number, e.g. Margin="a".

4 Numbers

If there are 4 numbers, then its left, top, right, bottom (a clockwise circle starting from the middle left margin). First number is always the "West" like "WPF":

<object Margin="left,top,right,bottom"/>

Example: if we use Margin="10,20,30,40" it generates:

2 Numbers

If there are 2 numbers, then the first is left & right margin thickness, the second is top & bottom margin thickness. First number is always the "West" like "WPF":

<object Margin="a,b"/> // Equivalent to Margin="a,b,a,b".

Example: if we use Margin="10,30", the left & right margin are both 10, and the top & bottom are both 30.

1 Number

If there is 1 number, then the number is repeated (its essentially a border thickness).

<object Margin="a"/> // Equivalent to Margin="a,a,a,a".

Example: if we use Margin="20" it generates:

Update 2020-05-27

Have been working on a large-scale WPF application for the past 5 years with over 100 screens. Part of a team of 5 WPF/C#/Java devs. We eventually settled on either using 1 number (for border thickness) or 4 numbers. We never use 2. It is consistent, and seems to be a good way to reduce cognitive load when developing.

The rule:

All width numbers start on the left (the "West" like "WPF") and go clockwise (if two numbers, only go clockwise twice, then mirror the rest).

I use this code modifying others that I saw. Only grand to the user write if the key pressed or pasted text pass the pattern test (match) (this example is a text input that only allows 8 digits)

$("input").on("keypress paste", function(e){
    var c = this.selectionStart, v = $(this).val();
    if (e.type == "keypress")
        var key = String.fromCharCode(!e.charCode ? e.which : e.charCode)
    else
        var key = e.originalEvent.clipboardData.getData('Text')
    var val = v.substr(0, c) + key + v.substr(c, v.length)
    if (!val.match(/\d{0,8}/) || val.match(/\d{0,8}/).toString() != val) {
        e.preventDefault()
        return false
    }
})

I think Citrix does that kind of thing. Though I'm not sure on specifics as I've only used it a couple of times. I think the one I used was called XenApp but I'm not sure if thats what you're after.

@drop-shadow if you're using Hibernate, you can call Hibernate.initialize() when you invoke the getStudents() method:

Public class UniversityDaoImpl extends GenericDaoHibernate<University, Integer> implements UniversityDao {
    //...
    @Override
    public University get(final Integer id) {
        Query query = getQuery("from University u where idUniversity=:id").setParameter("id", id).setMaxResults(1).setFetchSize(1);
        University university = (University) query.uniqueResult();
        ***Hibernate.initialize(university.getStudents());***
        return university;
    }
    //...
}

The "delete module-info.java at your Project Explorer tab" answer is the easiest and most straightforward answer, but

for those who would want a little more understanding or control of what's happening, the following alternate methods may be desirable;

• make an ever so slightly more realistic application; com.YourCompany.etc or just com.HelloWorld (Project name: com.HelloWorld and class name: HelloWorld)

or

• when creating the java project; when in the Create Java Project dialog, don't choose Finish but Next, and deselect Create module-info.java file

Anaconda with Windows

• Run anaconda prompt with administrator privilages
• conda update conda
• conda update --all
• conda install mingw libpython
• conda install theano

After conda commands it's required to accept process - Proceed ([y]/n)?

Client Side

Data needs to be grouped in an object array as payload - Indata:

var Indata = {'product': $scope.product, 'product2': $scope.product2 };

Pass the payload through $http.post as the second argument:

$http.post("http://localhost:53263/api/Products/", Indata).then(function (data, status, headers, config) { 
    alert("success"); 
},function (data, status, headers, config) { 
    alert("error"); 
});

Server Side

Create a Data Transfer Object(DTO) class as such:

public class ExampleRequest {
   public string product {get; set;};
   public string product2 {get; set;};
}

The class below accepts DTO with the same property names which the payload is carrying.

public void Post(ExampleRequest request)
{
    var productRepository = new ProductRepository();
    var newProduct = productRepository.Save(request.product);
}

In above class, request contains 2 properties with values of product and product2

If the problem is 100% here

EffectSelectorForm effectSelectorForm = new EffectSelectorForm(Effects);

There's only one possible explanation: property/variable "Effects" is not initialized properly... Debug your code to see what you pass to your objects.

EDIT after several hours

There were some problems:

• MEF attribute [Import] didn't work as expected, so we replaced it for the time being with a manually populated List<>. While the collection was null, it was causing exceptions later in the code, when the method tried to get the type of the selected item and there was none.

• several event handlers weren't wired up to control events

Some problems are still present, but I believe OP's original problem has been fixed. Other problems are not related to this one.

You can try :

  @media print {
    .table td,
    .table th {
        background-color: transparent !important;
        -webkit-print-color-adjust: exact !important;

    }
}

You can also use the command line, Change directory where your folder is located then type the following :

     git init
     git add <folder1> <folder2> <etc.>
     git commit -m "Your message about the commit"
     git remote add origin https://github.com/yourUsername/yourRepository.git
     git push -u origin master
     git push origin master  

Comparator is a functional interface, and Integer::max complies with that interface (after autoboxing/unboxing is taken into consideration). It takes two int values and returns an int - just as you'd expect a Comparator<Integer> to (again, squinting to ignore the Integer/int difference).

However, I wouldn't expect it to do the right thing, given that Integer.max doesn't comply with the semantics of Comparator.compare. And indeed it doesn't really work in general. For example, make one small change:

for (int i = 1; i <= 20; i++)
    list.add(-i);

... and now the max value is -20 and the min value is -1.

Instead, both calls should use Integer::compare:

System.out.println(list.stream().max(Integer::compare).get());
System.out.println(list.stream().min(Integer::compare).get());

You probably want os.makedirs as it will create intermediate directories as well, if needed.

import os

#dir is not keyword
def makemydir(whatever):
  try:
    os.makedirs(whatever)
  except OSError:
    pass
  # let exception propagate if we just can't
  # cd into the specified directory
  os.chdir(whatever)

When using JavaScript to access an HTML element, there is a good chance that the element is not on the page and therefore not in the dom as far as JavaScript is concerned, when the code to access that element runs.

This problem can occur even though you can visually see the HTML element in the browser window or have the code set to be called in the onload method.

I ran into this problem after writing code to repopulate specific div elements on a page after retrieving the cookies.

What is apparently happening is that even though the HTML has loaded and is outputted by the browser, the JavaScript code is running before the page has completed loading.

The solution to this problem which just may be a JavaScript bug, is to place the code you want to run within a timer that delays the code run by 400 milliseconds or so. You will need to test it to determine how quick you can run the code.

I also made a point to test for the element before attempting to assign values to it.

window.setTimeout(function() { if( document.getElementById("book") ) { // Code goes here }, 400 /* but after 400 ms */);

This may or may not help you solve your problem, but keep this in mind and understand that browsers do not always function as expected.

Don't use quotes with <<EOF:

var=$1
sudo tee "/path/to/outfile" > /dev/null <<EOF
Some text that contains my $var
EOF

Variable expansion is the default behavior inside of here-docs. You disable that behavior by quoting the label (with single or double quotes).

function sleep(delay) {
    var start = new Date().getTime();
    while (new Date().getTime() < start + delay);
}

This code blocks for the specified duration. This is CPU hogging code. This is different from a thread blocking itself and releasing CPU cycles to be utilized by another thread. No such thing is going on here. Do not use this code, it's a very bad idea.

To reload a page with jQuery, do:

$.ajax({
    url: "",
    context: document.body,
    success: function(s,x){
        $(this).html(s);
    }
});

The approach here that I used was Ajax jQuery. I tested it on Chrome 13. Then I put the code in the handler that will trigger the reload. The URL is "", which means this page.

In shell you assign to a variable without the dollar-sign:

TEST=`pwd`
echo $TEST

that's better (and can be nested) but is not as portable as the backtics:

TEST=$(pwd)
echo $TEST

Always remember: the dollar-sign is only used when reading a variable.

The reason the ImageView's dimentions are 0 is because when you are querying them, the view still haven't performed the layout and measure steps. You only told the view how it would "behave" in the layout, but it still didn't calculated where to put each view.

How do you decide the size to give to the image view? Can't you simply use one of the scaling options natively implemented?

Here is the Best Option for Dynamic className or Props , just do some concatenation like we do in Javascript.

     className={
        "badge " +
        (this.props.value ? "badge-primary " : "badge-danger ") +
        " m-4"
      }

If I understand your question correctly, you could use a small method like this to give you the results of your URL test:

WebRequest webRequest = WebRequest.Create(url);  
WebResponse webResponse;
try 
{
  webResponse = webRequest.GetResponse();
}
catch //If exception thrown then couldn't get response from address
{
  return 0;
} 
return 1;

You could wrap the above code in a method and use it to perform validation. I hope this answers the question you were asking.

I use AlamofireImage it works fine for me for Loading url within ImageView, which also has Placeholder option.

func setImage (){

  let image = “https : //i.imgur.com/w5rkSIj.jpg”
  if let url = URL (string: image)
  {
    //Placeholder Image which was in your Local(Assets)
    let image = UIImage (named: “PlacehoderImageName”)
    imageViewName.af_setImage (withURL: url, placeholderImage: image)
  }

}

Note:- Dont forget to Add AlamofireImage in your Pod file as well as in Import Statment

Say Example,

pod 'AlamofireImage' within Your PodFile and in ViewController import AlamofireImage

If you want to run the same command on multiple instances you can do this :

for i in c1 dm1 dm2 ds1 ds2 gtm_m gtm_sl; do docker exec -it $i /bin/bash -c "service sshd start"; done

The following works:

git add -A .
git stash
git stash drop stash@{0}

Please note that this will discard both your unstaged and staged local changes. So you should commit anything you want to keep, before you run these commands.

A typical use case: You moved a lot of files or directories around, and then want to get back to the original state.

Create a XIB file :

File -> new File ->ios->cocoa touch class -> next

make sure check mark "also create XIB file"

I would like to perform with tableview so I choosed subclass UITableViewCell

you can choose as your requerment

XIB file desing as your wish (RestaurantTableViewCell.xib)

we need to grab the row height to set table each row hegiht

Now! need to huck them swift file . i am hucked the restaurantPhoto and restaurantName you can huck all of you .

Now adding a UITableView

name
The name of the nib file, which need not include the .nib extension.

owner
The object to assign as the nib’s File's Owner object.

options
A dictionary containing the options to use when opening the nib file.

first if you do not define first then grabing all view .. so you need to grab one view inside that set frist .

Bundle.main.loadNibNamed("yourUIView", owner: self, options: nil)?.first as! yourUIView

here is table view controller Full code

import UIKit

class RestaurantTableViewController: UIViewController ,UITableViewDataSource,UITableViewDelegate{

    override func viewDidLoad() {
        super.viewDidLoad()

        // Do any additional setup after loading the view.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    func numberOfSections(in tableView: UITableView) -> Int {
        return 1
    }

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return 5
    }
    func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let restaurantTableviewCell = Bundle.main.loadNibNamed("RestaurantTableViewCell", owner: self, options: nil)?.first as! RestaurantTableViewCell

        restaurantTableviewCell.restaurantPhoto.image = UIImage(named: "image1")
        restaurantTableviewCell.restaurantName.text = "KFC Chicken"

        return restaurantTableviewCell
    }
   // set row height
    func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
        return 150
    }

}

you done :)

Finally below works for me

$("#priceSlider").slider('option',{min: 5, max: 20,value:[6,19]}); $("#priceSlider").slider("refresh");

You can create new User library,

On

"Configure Build Paths" page -> Add Library -> User Library (on list) -> User Libraries Button (rigth side of page)

and create your library and (add Jars buttons) include your specific Jars.

I hope this can help you.

To avoid getting the warning in a push navigation, you can directly use :

[self.view.window.rootViewController presentViewController:viewController animated:YES completion:nil];

And then in your modal view controller, when everything is finished, you can just call :

[self dismissViewControllerAnimated:YES completion:nil];

I had the same problem, After lots of googling, I couldn't find out how to fix it.

Suddenly I noticed my stupid mistake :)

As mentioned in the docs, the last part of docker run is the command you want to run and its arguments after loading up the container.

NOT THE CONTAINER NAME !!!

That was my embarrassing mistake.

Below I provided you with the picture of my command line to see what I have done wrong.

And this is the fix as mentioned in the docs.

now, for dplyr, adding a distinct counter.

df %>%
    group_by(aa, bb) %>%
    summarise(first=head(value,1), count=n_distinct(value))

You create groups, them summarise within groups.

If data is numeric, you can use:
first(value) [there is also last(value)] in place of head(value, 1)

see: http://cran.rstudio.com/web/packages/dplyr/vignettes/introduction.html

Full:

If you have this val="-12XXX.0abc23" and you want to extract only the decimal number, in this case this regex (^-?[0-9]\d*(\.\d+)?$) will not help you to achieve it.
this is the proper code with the correct detection regex:

var val="-12XXX.0abc23";_x000D_
val = val.replace(/^\.|[^-?\d\.]|\.(?=.*\.)|^0+(?=\d)/g, '');_x000D_
console.log(val);

this statement

DBMS_OUTPUT.PUT_LINE('a.firstName' || 'a.lastName');

means to print the string as it is.. remove the quotes to get the values to be printed.So the correct syntax is

DBMS_OUTPUT.PUT_LINE(a.firstName || a.lastName);

For Python 2, see and use pytz.

there is also a sneak way with pandas:

pd.to_timedelta(x) - pd.to_timedelta(y)

I would be very careful with self closing tags as this example demonstrates:

var a = '<span/><span/>';
var d = document.createElement('div');
d.innerHTML = a
console.log(d.innerHTML) // "<span><span></span></span>"

My gut feeling would have been <span></span><span></span> instead

I was facing same issue for changing default gradle version from 5.0 to 4.7, Below are the steps to change default gradle version in intellij
1) Change gradle version in gradle/wrapper/gradle-wrapper.properties in this property distributionUrl

2) Hit refresh button in gradle projects menu so that it will start downloading new gradle zip version

<br /> works for me

So...

String body = String.Format(@"New user:

Produces...

New user:
Name: Name
Email: Email
Phone: Phone

Code snippet underneath!

Please take a look at these documentations and examples at MDN, and you will find your answer. This is the propper way to do it I would say.

Creating and triggering events

Dispatch Event (example)

Taken from the 'Dispatch Event (example)'-HTML-link (simulate click):

function simulateClick() {

  var evt = document.createEvent("MouseEvents");

  evt.initMouseEvent("click", true, true, window,
    0, 0, 0, 0, 0, false, false, false, false, 0, null);

  var cb = document.getElementById("checkbox"); 
  var canceled = !cb.dispatchEvent(evt);

  if(canceled) {
    // A handler called preventDefault
    alert("canceled");
  } else {
    // None of the handlers called preventDefault
    alert("not canceled");
  }
}

This is how I would do it (2017 ..) :

Simply using MouseEvent.

function simulateClick() {

    var evt = new MouseEvent("click");

    var cb = document.getElementById("checkbox");
    var canceled = !cb.dispatchEvent(evt);

    if (canceled) {
        // A handler called preventDefault
        console.log("canceled");
    } else {
        // None of the handlers called preventDefault
        console.log("not canceled");
    }
}

document.getElementById("button").onclick = evt => {_x000D_
    _x000D_
    simulateClick()_x000D_
}_x000D_
_x000D_
function simulateClick() {_x000D_
_x000D_
    var evt = new MouseEvent("click");_x000D_
_x000D_
    var cb = document.getElementById("checkbox");_x000D_
    var canceled = !cb.dispatchEvent(evt);_x000D_
_x000D_
    if (canceled) {_x000D_
        // A handler called preventDefault_x000D_
        console.log("canceled");_x000D_
    } else {_x000D_
        // None of the handlers called preventDefault_x000D_
        console.log("not canceled");_x000D_
    }_x000D_
}

<input type="checkbox" id="checkbox">_x000D_
<br>_x000D_
<br>_x000D_
<button id="button">Check it out, or not</button>

after your comment try this one in evelated prompt :

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

Complex types are in the C language since C99 standard (-std=c99 option of GCC). Some compilers may implement complex types even in more earlier modes, but this is non-standard and non-portable extension (e.g. IBM XL, GCC, may be intel,... ).

You can start from http://en.wikipedia.org/wiki/Complex.h - it gives a description of functions from complex.h

This manual http://pubs.opengroup.org/onlinepubs/009604499/basedefs/complex.h.html also gives some info about macros.

To declare a complex variable, use

  double _Complex  a;        // use c* functions without suffix

or

  float _Complex   b;        // use c*f functions - with f suffix
  long double _Complex c;    // use c*l functions - with l suffix

To give a value into complex, use _Complex_I macro from complex.h:

  float _Complex d = 2.0f + 2.0f*_Complex_I;

(actually there can be some problems here with (0,-0i) numbers and NaNs in single half of complex)

Module is cabs(a)/cabsl(c)/cabsf(b); Real part is creal(a), Imaginary is cimag(a). carg(a) is for complex argument.

To directly access (read/write) real an imag part you may use this unportable GCC-extension:

 __real__ a = 1.4;
 __imag__ a = 2.0;
 float b = __real__ a;

Here is how you do it:

In .h

#ifdef BUILD_DLL
#define EXPORT __declspec(dllexport)
#else
#define EXPORT __declspec(dllimport)
#endif

extern "C" // Only if you are using C++ rather than C
{    
  EXPORT int __stdcall add2(int num);
  EXPORT int __stdcall mult(int num1, int num2);
}

in .cpp

extern "C" // Only if you are using C++ rather than C
{    
EXPORT int __stdcall add2(int num)
{
  return num + 2;
}


EXPORT int __stdcall mult(int num1, int num2)
{
  int product;
  product = num1 * num2;
  return product;
}
}

The macro tells your module (i.e your .cpp files) that they are providing the dll stuff to the outside world. People who incude your .h file want to import the same functions, so they sell EXPORT as telling the linker to import. You need to add BUILD_DLL to the project compile options, and you might want to rename it to something obviously specific to your project (in case a dll uses your dll).

You might also need to create a .def file to rename the functions and de-obfuscate the names (C/C++ mangles those names). This blog entry might be an interesting launching off point about that.

Loading your own custom dlls is just like loading system dlls. Just ensure that the DLL is on your system path. C:\windows\ or the working dir of your application are an easy place to put your dll.

The WebClient class should be more than capable of handling the functionality you describe, for example:

System.Net.WebClient wc = new System.Net.WebClient();
byte[] raw = wc.DownloadData("http://www.yoursite.com/resource/file.htm");

string webData = System.Text.Encoding.UTF8.GetString(raw);

or (further to suggestion from Fredrick in comments)

System.Net.WebClient wc = new System.Net.WebClient();
string webData = wc.DownloadString("http://www.yoursite.com/resource/file.htm");

When you say it took 30 seconds, can you expand on that a little more? There are many reasons as to why that could have happened. Slow servers, internet connections, dodgy implementation etc etc.

You could go a level lower and implement something like this:

HttpWebRequest webRequest = (HttpWebRequest)WebRequest.Create("http://www.yoursite.com/resource/file.htm");

using (StreamWriter streamWriter = new StreamWriter(webRequest.GetRequestStream(), Encoding.UTF8))
{
    streamWriter.Write(requestData);
}

string responseData = string.Empty;
HttpWebResponse httpResponse = (HttpWebResponse)webRequest.GetResponse();
using (StreamReader responseReader = new StreamReader(httpResponse.GetResponseStream()))
{
    responseData = responseReader.ReadToEnd();
}

However, at the end of the day the WebClient class wraps up this functionality for you. So I would suggest that you use WebClient and investigate the causes of the 30 second delay.

I received the same error when I tried to call https web service as http webservice.

e.g when I call url 'http://api.example.com/users/get'
which should be 'https://api.example.com/users/get'

This error is produced because of redirection status 302 when you try to call http instead of https.

All you need to do is use the file object as an iterator.

for line in open("log.txt"):
    do_something_with(line)

Even better is using context manager in recent Python versions.

with open("log.txt") as fileobject:
    for line in fileobject:
        do_something_with(line)

This will automatically close the file as well.

Try it this way. Put the table name in quotes (``). beside put variable '".$xyz."'.

So your sql query will be like:

$sql = mysql_query("UPDATE `anstalld` SET mandag = "'.$mandag.'" WHERE namn =".$name)or die(mysql_error());

I found a detailed solution here: Install OpenSSL Manually On Linux

From the blog post...:

Steps to download, compile, and install are as follows (I'm installing version 1.0.1g below; please replace "1.0.1g" with your version number):

Step – 1 : Downloading OpenSSL:

Run the command as below :

$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz

Also, download the MD5 hash to verify the integrity of the downloaded file for just varifacation purpose. In the same folder where you have downloaded the OpenSSL file from the website :

$ wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz.md5
$ md5sum openssl-1.0.1g.tar.gz
$ cat openssl-1.0.1g.tar.gz.md5

Step – 2 : Extract files from the downloaded package:

$ tar -xvzf openssl-1.0.1g.tar.gz

Now, enter the directory where the package is extracted like here is openssl-1.0.1g

$ cd openssl-1.0.1g

Step – 3 : Configuration OpenSSL

Run below command with optional condition to set prefix and directory where you want to copy files and folder.

$ ./config --prefix=/usr/local/openssl --openssldir=/usr/local/openssl

You can replace “/usr/local/openssl” with the directory path where you want to copy the files and folders. But make sure while doing this steps check for any error message on terminal.

Step – 4 : Compiling OpenSSL

To compile openssl you will need to run 2 command : make, make install as below :

$ make

Note: check for any error message for verification purpose.

Step -5 : Installing OpenSSL:

$ sudo make install

Or without sudo,

$ make install

That’s it. OpenSSL has been successfully installed. You can run the version command to see if it worked or not as below :

$ /usr/local/openssl/bin/openssl version

OpenSSL 1.0.1g 7 Apr 2014

Assuming that you are using UTF-8 encoding:

string convert = "This is the string to be converted";

// From string to byte array
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(convert);

// From byte array to string
string s = System.Text.Encoding.UTF8.GetString(buffer, 0, buffer.Length);

This is my preferred method. Pretty straight forward:

+1 to @MartinNuc, you can run the mysql client in batch mode and then you won't see the long stream of "OK" lines.

The amount of time it takes to import a given SQL file depends on a lot of things. Not only the size of the file, but the type of statements in it, how powerful your server server is, and how many other things are running at the same time.

@MartinNuc says he can load 4GB of SQL in 4-5 minutes, but I have run 0.5 GB SQL files and had it take 45 minutes on a smaller server.

We can't really guess how long it will take to run your SQL script on your server.

Re your comment,

@MartinNuc is correct you can choose to make the mysql client print every statement. Or you could open a second session and run mysql> SHOW PROCESSLIST to see what's running. But you probably are more interested in a "percentage done" figure or an estimate for how long it will take to complete the remaining statements.

Sorry, there is no such feature. The mysql client doesn't know how long it will take to run later statements, or even how many there are. So it can't give a meaningful estimate for how much time it will take to complete.

for (int j = 0; j < 5; j++) //inner loop should be replaced with for (int j = 0; j < 5 && !exitloops; j++).

Here, in this case complete nested loops should be exit if condition is True . But if we use exitloops only to the upper loop

 for (int i = 0; i < 5 && !exitloops; i++) //upper loop

Then inner loop will continues, because there is no extra flag that notify this inner loop to exit.

Example : if i = 3 and j=2 then condition is false. But in next iteration of inner loop j=3 then condition (i*j) become 9 which is true but inner loop will be continue till j become 5.

So, it must use exitloops to the inner loops too.

boolean exitloops = false;
for (int i = 0; i < 5 && !exitloops; i++) { //here should exitloops as a Conditional Statement to get out from the loops if exitloops become true. 
    for (int j = 0; j < 5 && !exitloops; j++) { //here should also use exitloops as a Conditional Statement. 
        if (i * j > 6) {
            exitloops = true;
            System.out.println("Inner loop still Continues For i * j is => "+i*j);
            break;
        }
        System.out.println(i*j);
    }
}

drawnonward's code is very close, but collides with UIKit's namespace and could be made easier to use.

@interface KeyboardStateListener : NSObject {
    BOOL _isVisible;
}
+ (KeyboardStateListener *)sharedInstance;
@property (nonatomic, readonly, getter=isVisible) BOOL visible;
@end

static KeyboardStateListener *sharedInstance;

@implementation KeyboardStateListener

+ (KeyboardStateListener *)sharedInstance
{
    return sharedInstance;
}

+ (void)load
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    sharedInstance = [[self alloc] init];
    [pool release];
}

- (BOOL)isVisible
{
    return _isVisible;
}

- (void)didShow
{
    _isVisible = YES;
}

- (void)didHide
{
    _isVisible = NO;
}

- (id)init
{
    if ((self = [super init])) {
        NSNotificationCenter *center = [NSNotificationCenter defaultCenter];
        [center addObserver:self selector:@selector(didShow) name:UIKeyboardDidShowNotification object:nil];
        [center addObserver:self selector:@selector(didHide) name:UIKeyboardWillHideNotification object:nil];
    }
    return self;
}

@end

When you opening modal on a tag and want show tooltip and if you implement tooltip inside tag it will show tooltip nearby tag. like this

I will suggest that use div outside a tag and use "display: inline-block;"

<div data-toggle="tooltip" title="" data-original-title="Add" style=" display inline-block;">
    <a class="btn btn-primary" data-toggle="modal" data-target="#myModal" onclick="setSelectedRoleId(6)">
     <span class="fa fa-plus"></span>
    </a>
</div>

In Firefox at least, the DOM inspector is telling me that the File input elements have a property called files. You should be able to check its length.

document.getElementById('myFileInput').files.length

My solution results in a syntax like this:

// Checking to see if var 'column' is in array ['a', 'b', 'c']

if (column.isAmong(['a', 'b', 'c']) {
  // Do something
}

And I implement this by extending the basic Object prototype, like this:

Object.prototype.isAmong = function (MyArray){
   for (var a=0; a<MyArray.length; a++) {
      if (this === MyArray[a]) { 
          return true;
      }
   }
   return false;
}

We might alternatively name the method isInArray (but probably not inArray) or simply isIn.

Advantages: Simple, straightforward, and self-documenting.

You only need to check if response is ok coz the call not returning anything.

var json = {
    json: JSON.stringify({
        a: 1,
        b: 2
    }),
    delay: 3
};

fetch('/echo/json/', {
    method: 'post',
    headers: {
        'Accept': 'application/json, text/plain, */*',
        'Content-Type': 'application/json'
    },
    body: 'json=' + encodeURIComponent(JSON.stringify(json.json)) + '&delay=' + json.delay
})
.then((response) => {if(response.ok){alert("the call works ok")}})
.catch (function (error) {
    console.log('Request failed', error);
});    

I find myself a tad amazed at the lack of what I consider the best answer to this question anywhere on the internet. I struggled for many years to find the answer. Many answers online come close, but none really answer it. The real answer is

(cmd & echo.) >2 & (set /p =)<2

The "secret sauce" being the "closely guarded coveted secret" that "echo." sends a CR/LF (ENTER/new line/0x0D0A). Otherwise, what I am doing here is redirecting the output of the first command to the standard error stream. I then redirect the standard error stream into the standard input stream for the "set /p =" command.

Example:

(echo foo & echo.) >2 & (set /p bar=)<2

Operating System as the inspiration

The operating system is also a program, so we can also create our own program by creating from scratch or changing (limiting or adding) features of one of the small operating systems, and then run it during the boot process (using an ISO image).

For example, this page can be used as a starting point:

How to write a simple operating system

Here, the entire Operating System fit entirely in a 512-byte boot sector (MBR)!

Such or similar simple OS can be used to create a simple framework that will allow us:

make the bootloader load subsequent sectors on the disk into RAM, and jump to that point to continue execution. Or you could read up on FAT12, the filesystem used on floppy drives, and implement that.

There are many possibilities, however. For for example to see a bigger x86 assembly language OS we can explore the MykeOS, x86 operating system which is a learning tool to show the simple 16-bit, real-mode OSes work, with well-commented code and extensive documentation.

Boot Loader as the inspiration

Other common type of programs that run without the operating system are also Boot Loaders. We can create a program inspired by such a concept for example using this site:

How to develop your own Boot Loader

The above article presents also the basic architecture of such a programs:

1. Correct loading to the memory by 0000:7C00 address.
2. Calling the BootMain function that is developed in the high-level language.
3. Show “”Hello, world…”, from low-level” message on the display.

As we can see, this architecture is very flexible and allows us to implement any program, not necessarily a boot loader.

In particular, it shows how to use the "mixed code" technique thanks to which it is possible to combine high-level constructions (from C or C++) with low-level commands (from Assembler). This is a very useful method, but we have to remember that:

to build the program and obtain executable file you will need the compiler and linker of Assembler for 16-bit mode. For C/C++ you will need only the compiler that can create object files for 16-bit mode.

The article shows also how to see the created program in action and how to perform its testing and debug.

UEFI applications as the inspiration

The above examples used the fact of loading the sector MBR on the data medium. However, we can go deeper into the depths by plaing for example with the UEFI applications:

Beyond loading an OS, UEFI can run UEFI applications, which reside as files on the EFI System Partition. They can be executed from the UEFI command shell, by the firmware's boot manager, or by other UEFI applications. UEFI applications can be developed and installed independently of the system manufacturer.

A type of UEFI application is an OS loader such as GRUB, rEFInd, Gummiboot, and Windows Boot Manager; which loads an OS file into memory and executes it. Also, an OS loader can provide a user interface to allow the selection of another UEFI application to run. Utilities like the UEFI shell are also UEFI applications.

If we would like to start creating such programs, we can, for example, start with these websites:

Programming for EFI: Creating a "Hello, World" Program / UEFI Programming - First Steps

Exploring security issues as the inspiration

It is well known that there is a whole group of malicious software (which are programs) that are running before the operating system starts.

A huge group of them operate on the MBR sector or UEFI applications, just like the all above solutions, but there are also those that use another entry point such as the Volume Boot Record (VBR) or the BIOS:

There are at least four known BIOS attack viruses, two of which were for demonstration purposes.

or perhaps another one too.

Attacks before system startup

Bootkits have evolved from Proof-of-Concept development to mass distribution and have now effectively become open-source software.

Different ways to boot

I also think that in this context it is also worth mentioning that there are various forms of booting the operating system (or the executable program intended for this). There are many, but I would like to pay attention to loading the code from the network using Network Boot option (PXE), which allows us to run the program on the computer regardless of its operating system and even regardless of any storage medium that is directly connected to the computer:

What Is Network Booting (PXE) and How Can You Use It?

I wanted the dropdown to select the matching value of the id in the action method. The trick is to set the Selected property when creating the SelectListItem Collection. It would not work any other way, perhaps I missed something but in end, it is more elegant in my option.

You can write any method that returns a boolean to set the Selected value based on your requirements, in my case I used the existing Equal Method

public ActionResult History(long id)
        {
            var app = new AppLogic();
            var historyVM = new ActivityHistoryViewModel();

            historyVM.ProcessHistory = app.GetActivity(id);
            historyVM.Process = app.GetProcess(id);
            var processlist = app.GetProcessList();

            historyVM.ProcessList = from process in processlist
                                    select new SelectListItem
                                    {
                                        Text = process.ProcessName,
                                        Value = process.ID.ToString(),
                                        Selected = long.Equals(process.ID, id)                                    

                                    };

            var listitems = new List<SelectListItem>();

            return View(historyVM);
        }

Old fashioned way:

for ix in range(len(ints)):
    print ints[ix]

List comprehension:

[ (ix, ints[ix]) for ix in range(len(ints))]

>>> ints
[1, 2, 3, 4, 5]
>>> for ix in range(len(ints)): print ints[ix]
... 
1
2
3
4
5
>>> [ (ix, ints[ix]) for ix in range(len(ints))]
[(0, 1), (1, 2), (2, 3), (3, 4), (4, 5)]
>>> lc = [ (ix, ints[ix]) for ix in range(len(ints))]
>>> for tup in lc:
...     print tup
... 
(0, 1)
(1, 2)
(2, 3)
(3, 4)
(4, 5)
>>> 

var selectList = db.NewsClasses.ToList<NewsClass>().Select(a => new SelectListItem({
    Text = a.ClassName,
    Value = a.ClassId.ToString()
});

Firstly, convert to object, then toString() will be correct.

The proper way to initialize a multidimensional array in C or C++ is

int arr[2][5] = {{1,8,12,20,25}, {5,9,13,24,26}};

You can use this same trick to initialize even higher-dimensional arrays if you want.

Also, be careful in your initial code - you were trying to use 1-indexed offsets into the array to initialize it. This didn't compile, but if it did it would cause problems because C arrays are 0-indexed!

Best bet is to copy your folder. Delete the original. Clone the project from github, copy your new files into the new cloned folder, and then try again.

Please learn about automake and autoconf.

Makefile.am is processed by automake to generate a Makefile that is processed by make in order to build your sources.

http://www.gnu.org/software/automake/

You could try calling toString() on the prepared statement after you've set the bind values.

PreparedStatement query = connection.prepareStatement(aSQLStatement);
System.out.println("Before : " + query.toString());
query.setString(1, "Hello");
query.setString(2, "World");
System.out.println("After : " + query.toString());

This works when you use the JDBC MySQL driver, but I'm not sure if it will in other cases. You may have to keep track of all the bindings you make and then print those out.

Sample output from above code.

Before : com.mysql.jdbc.JDBC4PreparedStatement@fa9cf: SELECT * FROM test WHERE blah1=** NOT SPECIFIED ** and blah2=** NOT SPECIFIED **
After : com.mysql.jdbc.JDBC4PreparedStatement@fa9cf: SELECT * FROM test WHERE blah1='Hello' and blah2='World'

When we want to take Integer as inputs
For just 3 inputs as in your case:

import java.util.Scanner;
Scanner scan = new Scanner(System.in);
int a,b,c;
a = scan.nextInt();
b = scan.nextInt();
c = scan.nextInt();

For more number of inputs we can use a loop:

import java.util.Scanner;
Scanner scan = new Scanner(System.in);
int a[] = new int[n]; //where n is the number of inputs
for(int i=0;i<n;i++){
    a[i] = scan.nextInt();    
}

For posterity, also check server logs to see if the resource being requested is returning a 200.

I ran into a similar issue, where all of the proper headers were being returned in the pre-flight ajax request, but the browser reported the actual request was blocked due to bad CORS headers.

Turns out, the page being requested was returning a 500 error due to bad code, but only when it was fetched via CORS. The browser (both Chrome and Firefox) mistakenly reported that the Access-Control-Allow-Origin header was missing instead of saying the page returned a 500.

To find where the name google clashes .... try this:

python3

then >>> help('google')

... I got info about google-auth:

Also then try

pip show google-auth

Then

sudo pip3 uninstall google-auth

... and re-try >>> help('google')

I then see protobuf:

Print all args without the filename:

for i in range(1, len(sys.argv)):
print(sys.argv[i])

The xor operator is ^

For example: SELECT A ^ B where A and B are integer category data types.

Taken from somewhere on the web but I've been using it for a while and it works well.

On this web page, I see that:

"Remember that the dot is not a metacharacter inside a character class, so we do not need to escape it with a backslash."

So I guess the escaping of it is unnecessary...

Send the data from the form:

  url: url
  dataType: "script"

In my case was webpack having the UglifyPlugin running with drop_console: true set

You could use ng-init in an outer div:

<div ng-init="param='value';">
    <div ng-controller="BasketController" >
        <label>param: {{value}}</label>
    </div>
</div>  

The parameter will then be available in your controller's scope:

function BasketController($scope) {
        console.log($scope.param);
}

None of the answers helped me (I had my pods linked with all targets, build configurations setup properly, correclty set search paths "$(inherited)", etc...).

Problem disappeared by itself after I updated cocoapods to the newest, debug version using standard install / update command:

   gem install cocoapods --pre

or:

   sudo gem install cocoapods --pre

(if sudo was used during installation).

It must have been cocoapods bug.

Make is behaving correctly. hello already exists and is not older than the .c files, and therefore there is no more work to be done. There are four scenarios in which make will need to (re)build:

• If you modify one of your .c files, then it will be newer than hello, and then it will have to rebuild when you run make.
• If you delete hello, then it will obviously have to rebuild it
• You can force make to rebuild everything with the -B option. make -B all
• make clean all will delete hello and require a rebuild. (I suggest you look at @Mat's comment about rm -f *.o hello

The method jQuery (v1.10) uses to find this is:

var doc = document.documentElement;
var left = (window.pageXOffset || doc.scrollLeft) - (doc.clientLeft || 0);
var top = (window.pageYOffset || doc.scrollTop)  - (doc.clientTop || 0);

That is:

• It tests for window.pageXOffset first and uses that if it exists.
• Otherwise, it uses document.documentElement.scrollLeft.
• It then subtracts document.documentElement.clientLeft if it exists.

The subtraction of document.documentElement.clientLeft / Top only appears to be required to correct for situations where you have applied a border (not padding or margin, but actual border) to the root element, and at that, possibly only in certain browsers.

After finding this StackOverflow question/answer

Complex type is getting null in a ApiController parameter

the [FromBody] attribute on the controller method needs to be [FromUri] since a GET does not have a body. After this change the "filter" complex object is passed correctly.

You import the function from outside the main instance, and don't add it to the methods block. so the context of this is not the vm.

Either do this:

ready() {
  checkAuth.call(this)
}

or add the method to your methods first (which will make Vue bind this correctly for you) and call this method:

methods: {
  checkAuth: checkAuth
},
ready() {
  this.checkAuth()
}

you can use glob function to do this. see the example

import cv2
import glob
for img in glob.glob("path/to/folder/*.png"):
    cv_img = cv2.imread(img)

using outline:none; we can remove that border in chrome

<style>
input[type="button"]
{
    width:120px;
    height:60px;
    margin-left:35px;
    display:block;
    background-color:gray;
    color:white;
    border: none;
    outline:none;
}
</style>

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

Simple JavaScript will do -

<form action="myservlet.do" method="POST">
    <select name="myselect" id="myselect" onchange="this.form.submit()">
        <option value="1">One</option>
        <option value="2">Two</option>
        <option value="3">Three</option>
        <option value="4">Four</option>
    </select>
</form>

Here is a link for a good javascript tutorial.

As an addition to answers above: you probably might need to change ids in names/ids of input elements (pls note, you should not have digits in fields name):

<input name="someStuff.entry[2].fieldOne" id="someStuff_fdf_fieldOne_2" ..>

I have done this having some global variable by default set to 0:

var globalNewIndex = 0;

and in the add function after you've cloned and resetted the values in the new row:

                var newIndex = globalNewIndex+1;
                var changeIds = function(i, val) {
                    return val.replace(globalNewIndex,newIndex);
                }
                $('#mytable tbody>tr:last input').attr('name', changeIds ).attr('id', changeIds );
                globalNewIndex++;

You can also just return string if you know that's the only thing the method will ever return. For example:

public string MyActionName() {
  return "Hi there!";
}

Remove the comma

... Gender,Contact, " + ") VALUES ...

Right after our long comment section, I think this is what you're looking for, it's jQuery based:

HTML:

<img width="100%" id="img" src="http://uploads8.wikipaintings.org/images/william-adolphe-bouguereau/self-portrait-presented-to-m-sage-1886.jpg">

JS:

<script type="text/javascript">
window.onload = function(){
       var img = document.getElementById('img')
       if(img.clientHeight<$(window).height()){
            img.style.height=$(window).height()+"px";
       }
       if(img.clientWidth<$(window).width()){
            img.style.width=$(window).width()+"px";
       } 
}
?</script>??????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????

CSS:

body{
    overflow: hidden;
}

?The code above is using the browsers width and height if you where doing this within a div, you would have to change it to something like this:

For Div:

HTML:

<div style="width:100px; max-height: 100px;" id="div">
     <img width="100%" id="img" src="http://uploads8.wikipaintings.org/images/william-adolphe-bouguereau/self-portrait-presented-to-m-sage-1886.jpg">
</div>

JS:

<script type="text/javascript">
window.onload = function(){
       var img = document.getElementById('img')
       if(img.clientHeight<$('#div').height()){
            img.style.height=$('#div').height()+"px";
       }
       if(img.clientWidth<$('#div').width()){
            img.style.width=$('#div').width()+"px";
       } 
}

I should also state that I've only tested this is Google Chrome... here is a jsfiddle: http://jsfiddle.net/ADCKk/

Can you try using document.location.replace() it is used to clear the last entry in the history and replace it with the address of a new url. replace() removes the URL of the current document from the document history, meaning that it is not possible to use the "back" button to navigate back to the original document.

<script type="text/javascript">
    function Navigate(){   
         window.location.replace('your link');
        return false;
    }
   </script>

HTML:

   <button onclick="Navigate()">Replace document</button>

If you are using RemoteDriver things are different. From http://element34.ca/blog/iedriverserver-webdriver-and-python :

You will need to start the server using a line like

java -jar selenium-server-standalone-2.26.0.jar -Dwebdriver.ie.driver=C:\Temp\IEDriverServer.exe

I found that if the IEDriverServer.exe was in C:\Windows\System32\ or its subfolders, it couldn't be found automatically (even though System32 was in the %PATH%) or explicitly using the -D flag.

Some more explanations to the solution Rachel already gave:

"WPF Apps With The Model-View-ViewModel Design Pattern"

by Josh Smith

http://msdn.microsoft.com/en-us/magazine/dd419663.aspx

First, we need to filter the XML so as to parse that change objects become array

//catch xml
$xmlElement = file_get_contents ('php://input');
//change become array
$Data = (array)simplexml_load_string($xmlElement);
//and see
print_r($Data);

Please follow the below steps.

begin
  for i in (select 'drop table '||table_name||' cascade constraints' tb from user_tables) 
  loop
     execute immediate i.tb;
  end loop;
  commit;
end;
purge RECYCLEBIN;

The difference are:

$(document).ready(function() { is jQuery event that is fired when DOM is loaded, so it’s fired when the document structure is ready.

$(window).load() event is fired after whole content is loaded.

Based on the answer from Luis, you can do something more like the default findBy method.

First, create a default repository class that is going to be used by all your entities.

/* $config is the entity manager configuration object. */
$config->setDefaultRepositoryClassName( 'MyCompany\Repository' );

Or you can edit this in config.yml

doctrine: orm: default_repository_class: MyCompany\Repository

Then:

<?php

namespace MyCompany;

use Doctrine\ORM\EntityRepository;

class Repository extends EntityRepository {

    public function findByNot( array $criteria, array $orderBy = null, $limit = null, $offset = null )
    {
        $qb = $this->getEntityManager()->createQueryBuilder();
        $expr = $this->getEntityManager()->getExpressionBuilder();

        $qb->select( 'entity' )
            ->from( $this->getEntityName(), 'entity' );

        foreach ( $criteria as $field => $value ) {
            // IF INTEGER neq, IF NOT notLike
            if($this->getEntityManager()->getClassMetadata($this->getEntityName())->getFieldMapping($field)["type"]=="integer") {
                $qb->andWhere( $expr->neq( 'entity.' . $field, $value ) );
            } else {
                $qb->andWhere( $expr->notLike( 'entity.' . $field, $qb->expr()->literal($value) ) );
            }
        }

        if ( $orderBy ) {

            foreach ( $orderBy as $field => $order ) {

                $qb->addOrderBy( 'entity.' . $field, $order );
            }
        }

        if ( $limit )
            $qb->setMaxResults( $limit );

        if ( $offset )
            $qb->setFirstResult( $offset );

        return $qb->getQuery()
            ->getResult();
    }

}

The usage is the same than the findBy method, example:

$entityManager->getRepository( 'MyRepo' )->findByNot(
    array( 'status' => Status::STATUS_DISABLED )
);

JSON can represent a wide variety of data structures -- a JS "object" is roughly like a Python dict (with string keys), a JS "array" roughly like a Python list, and you can nest them as long as the final "leaf" elements are numbers or strings.

CSV can essentially represent only a 2-D table -- optionally with a first row of "headers", i.e., "column names", which can make the table interpretable as a list of dicts, instead of the normal interpretation, a list of lists (again, "leaf" elements can be numbers or strings).

So, in the general case, you can't translate an arbitrary JSON structure to a CSV. In a few special cases you can (array of arrays with no further nesting; arrays of objects which all have exactly the same keys). Which special case, if any, applies to your problem? The details of the solution depend on which special case you do have. Given the astonishing fact that you don't even mention which one applies, I suspect you may not have considered the constraint, neither usable case in fact applies, and your problem is impossible to solve. But please do clarify!

The top voted answer is deprecated in Bootstrap 3.3 and will be removed in v4. Try this instead:

JavaScript:

// Fill modal with content from link href
$("#myModal").on("show.bs.modal", function(e) {
    var link = $(e.relatedTarget);
    $(this).find(".modal-body").load(link.attr("href"));
});

Html (Based on the official example. Note that for Bootstrap 3.* we set data-remote="false" to disable the deprecated Bootstrap load function):

<!-- Link trigger modal -->
<a href="remoteContent.html" data-remote="false" data-toggle="modal" data-target="#myModal" class="btn btn-default">
    Launch Modal
</a>

<!-- Default bootstrap modal example -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

Try it yourself: https://jsfiddle.net/ednon5d1/

Simply use str_replace:

$text = str_replace(' ', '_', $text);

You would do this after your previous substr and strtolower calls, like so:

$text = substr($text,0,10);
$text = strtolower($text);
$text = str_replace(' ', '_', $text);

If you want to get fancy, though, you can do it in one line:

$text = strtolower(str_replace(' ', '_', substr($text, 0, 10)));

mycollection.find_one_and_update({"_id": mongo_id}, 
                                 {"$set": {"newfield": "abc"}})

should work splendidly for you. If there is no document of id mongo_id, it will fail, unless you also use upsert=True. This returns the old document by default. To get the new one, pass return_document=ReturnDocument.AFTER. All parameters are described in the API.

The method was introduced for MongoDB 3.0. It was extended for 3.2, 3.4, and 3.6.

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

DEMO

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

DEMO

Don't over complicate.

  document.addEventListener('keydown', logKey);
    function logKey(e) {
      if (`${e.code}` == "ArrowRight") {
        //code here
      }
          if (`${e.code}` == "ArrowLeft") {
        //code here
      }
          if (`${e.code}` == "ArrowDown") {
        //code here
      }
          if (`${e.code}` == "ArrowUp") {
        //code here
      }
    }

Yes, Range :

The range form of the for loop iterates over a slice or map.

When ranging over a slice, two values are returned for each iteration. The first is the index, and the second is a copy of the element at that index.

Example :

package main

import "fmt"

var pow = []int{1, 2, 4, 8, 16, 32, 64, 128}

func main() {
    for i, v := range pow {
        fmt.Printf("2**%d = %d\n", i, v)
    }

    for i := range pow {
        pow[i] = 1 << uint(i) // == 2**i

• You can skip the index or value by assigning to _.
• If you only want the index, drop the , value entirely.

Try this:

sed "s/aaa=.*/aaa=xxx/g"

You can't do this: {this.state.arrayFromJson} As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map to do that.

I am pasting a link from where you can learn how to render elements from an array with React.

Hope it helps!

You'd better not to count the filesystem hits while you code in Javascript, in my opinion. However, (1) stat & mkdir and (2) mkdir and check(or discard) the error code, both ways are right ways to do what you want.

Most certainly, export JAVA_HOME=/usr/bin/java is the culprit. This env var should point to the JDK or JRE installation directory. Googling shows that the best option for MacOS X seems to be export JAVA_HOME=/Library/Java/Home.

Edit: OP (or an editor) silently changed some of the single quotes in the original question to double quotes at some point after I provided this answer.

Your code will result in compiler errors. Your first code fragment:

char buf[10] ; buf = ''

is doubly illegal. First, in C, there is no such thing as an empty char. You can use double quotes to designate an empty string, as with:

char* buf = ""; 

That will give you a pointer to a NUL string, i.e., a single-character string with only the NUL character in it. But you cannot use single quotes with nothing inside them--that is undefined. If you need to designate the NUL character, you have to specify it:

char buf = '\0';

The backslash is necessary to disambiguate from character '0'.

char buf = 0;

accomplishes the same thing, but the former is a tad less ambiguous to read, I think.

Secondly, you cannot initialize arrays after they have been defined.

char buf[10];

declares and defines the array. The array identifier buf is now an address in memory, and you cannot change where buf points through assignment. So

buf =     // anything on RHS

is illegal. Your second and third code fragments are illegal for this reason.

To initialize an array, you have to do it at the time of definition:

char buf [10] = ' ';

will give you a 10-character array with the first char being the space '\040' and the rest being NUL, i.e., '\0'. When an array is declared and defined with an initializer, the array elements (if any) past the ones with specified initial values are automatically padded with 0. There will not be any "random content".

If you declare and define the array but don't initialize it, as in the following:

char buf [10];

you will have random content in all the elements.

The SGI STL has an extension called select1st. Too bad it's not in standard STL!

Here's a one-liner to get the filename for a module, suitable for shell aliasing:

echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - 

Set up as an alias:

alias getpmpath="echo 'import sys; t=__import__(sys.argv[1],fromlist=[\".\"]); print(t.__file__)'  | python - "

To use:

$ getpmpath twisted
/usr/lib64/python2.6/site-packages/twisted/__init__.pyc
$ getpmpath twisted.web
/usr/lib64/python2.6/site-packages/twisted/web/__init__.pyc

add these lines to your .get/config file (thanks to @kovshenin answer Git Pull: Change Authentication) :

[credential]
    helper = wincred

It can be %f, %g or %e depending on how you want the number to be formatted. See here for more details. The l modifier is required in scanf with double, but not in printf.

A tool like systemtap (or a tracer) can monitor kernel signal-transmission logic and report. e.g., https://sourceware.org/systemtap/examples/process/sigmon.stp

# stap .../sigmon.stp -x 31994 SIGKILL
   SPID     SNAME            RPID  RNAME            SIGNUM SIGNAME
   5609     bash             31994 find             9      SIGKILL

The filtering if block in that script can be adjusted to taste, or eliminated to trace systemwide signal traffic. Causes can be further isolated by collecting backtraces (add a print_backtrace() and/or print_ubacktrace() to the probe, for kernel- and userspace- respectively).

There's a sightly larger plugin called vim-eunuch by Tim Pope that includes a rename function as well as some other goodies (delete, find, save all, chmod, sudo edit, ...).

To rename a file in vim-eunuch:

:Move filename.ext

Compared to rename.vim:

:rename[!] filename.ext

Saves a few keystrokes :)

Come out of the "python interpreter."

1. Check out your PATH variable c:\python27
2. cd and your file location. 3.Now type Python yourfilename.py.

I hope this should work
