You can use the getText() method anywhere in your code it is instancely called by your object, So you can use the method anywhere within a calass

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

The most efficient is to create a buffer of the correct size and then read the file into the buffer.

#include <fstream>
#include <vector>

int main()
{
    std::ifstream       file("Plop");
    if (file)
    {
        /*
         * Get the size of the file
         */
        file.seekg(0,std::ios::end);
        std::streampos          length = file.tellg();
        file.seekg(0,std::ios::beg);

        /*
         * Use a vector as the buffer.
         * It is exception safe and will be tidied up correctly.
         * This constructor creates a buffer of the correct length.
         * Because char is a POD data type it is not initialized.
         *
         * Then read the whole file into the buffer.
         */
        std::vector<char>       buffer(length);
        file.read(&buffer[0],length);
    }
}

add this line in your actiity when you adding tabs in tablayout

 tabLayout.setTabGravity(TabLayout.GRAVITY_FILL); 

GROUP BY DATE(date_time_column)

Well, take care of what you mean by "between" too...

days_apart = (to - from).to_i     # from + days_apart = to
total_days = (to - from).to_i + 1 # number of "selected" days
in_between_days = (to - from).to_i - 1 # how many days are in between from and to, i.e. excluding those two days

It's a very old post, but if it benefits anyone, we can do something like this:

Long max=((BigInteger) Collections.max(dynamics)).longValue(); 

Dictionary <<<>>> Hashtable differences:

• Generic <<<>>> Non-Generic
• Needs own thread synchronization <<<>>> Offers thread safe version through Synchronized() method
• Enumerated item: KeyValuePair <<<>>> Enumerated item: DictionaryEntry
• Newer (> .NET 2.0) <<<>>> Older (since .NET 1.0)
• is in System.Collections.Generic <<<>>> is in System.Collections
• Request to non-existing key throws exception <<<>>> Request to non-existing key returns null
• potentially a bit faster for value types <<<>>> bit slower (needs boxing/unboxing) for value types

Dictionary / Hashtable similarities:

• Both are internally hashtables == fast access to many-item data according to key
• Both need immutable and unique keys
• Keys of both need own GetHashCode() method

Similar .NET collections (candidates to use instead of Dictionary and Hashtable):

• ConcurrentDictionary - thread safe (can be safely accessed from several threads concurrently)
• HybridDictionary - optimized performance (for few items and also for many items)
• OrderedDictionary - values can be accessed via int index (by order in which items were added)
• SortedDictionary - items automatically sorted
• StringDictionary - strongly typed and optimized for strings

javapackager

The Java Packager tool compiles, packages, and prepares Java and JavaFX applications for distribution. The javapackager command is the command-line version.

– Oracle's documentation

The javapackager utility ships with the JDK. It can generate .exe files with the -native exe flag, among many other things.

WinRun4J

WinRun4j is a java launcher for windows. It is an alternative to javaw.exe and provides the following benefits:

• Uses an INI file for specifying classpath, main class, vm args, program args.
• Custom executable name that appears in task manager.
• Additional JVM args for more flexible memory use.
• Built-in icon replacer for custom icon.
• [more bullet points follow]

– WinRun4J's webpage

WinRun4J is an open source utility. It has many features.

packr

Packages your JAR, assets and a JVM for distribution on Windows, Linux and Mac OS X, adding a native executable file to make it appear like a native app. Packr is most suitable for GUI applications.

– packr README

packr is another open source tool.

JSmooth

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself.

– JSmooth's website

JSmooth is open source and has features, but it is very old. The last release was in 2007.

JexePack

JexePack is a command line tool (great for automated scripting) that allows you to package your Java application (class files), optionally along with its resources (like GIF/JPG/TXT/etc), into a single compressed 32-bit Windows EXE, which runs using Sun's Java Runtime Environment. Both console and windowed applications are supported.

– JexePack's website

JexePack is trialware. Payment is required for production use, and exe files created with this tool will display "reminders" without payment. Also, the last release was in 2013.

InstallAnywhere

InstallAnywhere makes it easy for developers to create professional installation software for any platform. With InstallAnywhere, you’ll adapt to industry changes quickly, get to market faster and deliver an engaging customer experience. And know the vulnerability of your project’s OSS components before you ship.

– InstallAnywhere's website

InstallAnywhere is a commercial/enterprise package that generates installers for Java-based programs. It's probably capable of creating .exe files.

Executable JAR files

As an alternative to .exe files, you can create a JAR file that automatically runs when double-clicked, by adding an entry point to the JAR manifest.

For more information

An excellent source of information on this topic is Excelsior's article "Convert Java to EXE – Why, When, When Not and How".

See also the companion article "Best JAR to EXE Conversion Tools, Free and Commercial".

This code give an animation like pushing viewController in uinavigation controller...

CATransition *animation = [CATransition animation];
 animation.type = kCATransitionPush;
 animation.subtype = kCATransitionFromRight;
 animation.duration = 0.3;
 [_viewAccountName.layer addAnimation:animation forKey:nil];

 _viewAccountName.hidden = true;

Used this for pop animation...

 CATransition *animation = [CATransition animation];
 animation.type = kCATransitionPush;
 animation.subtype = kCATransitionFromLeft;
 animation.duration = 0.3;
 [_viewAccountName.layer addAnimation:animation forKey:nil];

 _viewAccountName.hidden = false;

I think a better question is "When would you use @classmethod vs @staticmethod?"

@classmethod allows you easy access to private members that are associated to the class definition. this is a great way to do singletons, or factory classes that control the number of instances of the created objects exist.

@staticmethod provides marginal performance gains, but I have yet to see a productive use of a static method within a class that couldn't be achieved as a standalone function outside the class.

According to this it does have a Text property

http://msdn.microsoft.com/en-us/library/system.windows.forms.richtextbox_members.aspx

You can also try the "Lines" property if you want the text broken up as lines.

In my case, my dataframe has the following characteristics

The first option data.index = pd.to_datetime(data.index) returned

ParserError: String does not contain a date: ParserError: String does not contain a date:

The second option: data.index.to_datetime() returned

Another option I have tested is. data.index = pd.to_datetime(data.index)

It returned: ParserError: String does not contain a date:

What could be my problem? Thanks

in jquery ajax functions, the success callback signature is:

function (data, textStatus) {
  // data could be xmlDoc, jsonObj, html, text, etc...
  this; // the options for this ajax request
}

depending on the data type you've asked, using the 'dataType' parameter, you'll get the 'data' argument.

from the docs:

dataType (String) Default: Intelligent Guess (xml or html). The type of data that you're expecting back from the server. If none is specified, jQuery will intelligently pass either responseXML or responseText to your success callback, based on the MIME type of the response.

The available types (and the result passed as the first argument to your success callback) are:

"xml": Returns a XML document that can be processed via jQuery.

"html": Returns HTML as plain text; included script tags are evaluated when inserted in the DOM.

"script": Evaluates the response as JavaScript and returns it as plain text. Disables caching unless option "cache" is used. Note: This will turn POSTs into GETs for remote-domain requests.

"json": Evaluates the response as JSON and returns a JavaScript Object.

"jsonp": Loads in a JSON block using JSONP. Will add an extra "?callback=?" to the end of your URL to specify the callback. (Added in jQuery 1.2)

"text": A plain text string.

see http://docs.jquery.com/Ajax/jQuery.ajax#options

IE 7 and previous versions sent the full path of the uploaded file to the server related to the input type="file" field. Firefox and other modern browsers consider this to be a security flaw and do not. However, this appears to be have been fixed in IE 8.

Perhaps you should instead evaluate why you need the full path to the file as it was located on the client's system. I think it is really superfluous information that should never be posted at all. All you should be concerned with the is the file name so that you can save the file without making changes to the name.

You can use JavaScript as well, in case the textfield is dithered.

WebDriver driver=new FirefoxDriver();
driver.get("http://localhost/login.do");
driver.manage().window().maximize();
RemoteWebDriver r=(RemoteWebDriver) driver;
String s1="document.getElementById('username').value='admin'";
r.executeScript(s1);

The answers so far tell you how to find existing branches:

git branch -r

Or repositories for the same project [see note below]:

git remote -v

There is another case. You might want to know about other project repositories hosted on the same server.

To discover that information, I use SSH or PuTTY to log into to host and ls to find the directories containing the other repositories. For example, if I cloned a repository by typing:

git clone ssh://git.mycompany.com/git/ABCProject

and want to know what else is available, I log into git.mycompany.com via SSH or PuTTY and type:

ls /git

assuming ls says:

 ABCProject DEFProject

I can use the command

 git clone ssh://git.mycompany.com/git/DEFProject

to gain access to the other project.

NOTE: Usually git remote simply tells me about origin -- the repository from which I cloned the project. git remote would be handy if you were collaborating with two or more people working on the same project and accessing each other's repositories directly rather than passing everything through origin.

I found the answer to may previous post. Here it is.

CREATE TABLE #TempTable (id int) 

INSERT INTO @TestTable (col1, col2) OUTPUT INSERTED.id INTO #TempTable select 1,2 

INSERT INTO @TestTable (col1, col2) OUTPUT INSERTED.id INTO #TempTable select 3,4 

SELECT * FROM #TempTable --this select will chage @@ROWCOUNT value

This is quite handy to use:

var myRedirect = function(redirectUrl, arg, value) {
  var form = $('<form action="' + redirectUrl + '" method="post">' +
  '<input type="hidden" name="'+ arg +'" value="' + value + '"></input>' + '</form>');
  $('body').append(form);
  $(form).submit();
};

then use it like:

myRedirect("/yourRedirectingUrl", "arg", "argValue");

I had the same issue and atom-goto-definition (package name goto-definition) worked like charm for me. Please try once. You can download directly from Atom.

This package is DEPRECATED. Please check it in Github.

Something that works for me. Enjoy.

Does it re-import every time the function is run?

No; or rather, Python modules are essentially cached every time they are imported, so importing a second (or third, or fourth...) time doesn't actually force them to go through the whole import process again. 1

Does it import once at the beginning whether or not the function is run?

No, it is only imported if and when the function is executed. 2, 3

As for the benefits: it depends, I guess. If you may only run a function very rarely and don't need the module imported anywhere else, it may be beneficial to only import it in that function. Or if there is a name clash or other reason you don't want the module or symbols from the module available everywhere, you may only want to import it in a specific function. (Of course, there's always from my_module import my_function as f for those cases.)

In general practice, it's probably not that beneficial. In fact, most Python style guides encourage programmers to place all imports at the beginning of the module file.

If you know that the collection is a queue then you can cast the collection to a queue and get it easily.

There are several structures you can use to get the order, but you will need to cast to it.

SQLite doesn't define any particular extension for this, it's your own choice. Personally, I name them with the .sqlite extension, just so there isn't any ambiguity when I'm looking at my files later.

since I had already compiled opencv when I discovered this problem, all I had to do was (from my opencv build directory):

make opencv_nonfree
sudo make install

In case this helps anyone :

static bool myFunction(Node& p1, Node& p2) {}
priority_queue <Node, vector<Node>, function<bool(Node&, Node&)>> pq1(myFunction);

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

Another way is to use tidy evaluation approach. It is pretty straightforward to pass columns of a data frame either as strings or bare column names. See more about tidyeval here.

library(rlang)
library(tidyverse)

set.seed(123)
df <- data.frame(B = rnorm(10), D = rnorm(10))

Use column names as strings

fun3 <- function(x, ...) {
  # capture strings and create variables
  dots <- ensyms(...)
  # unquote to evaluate inside dplyr verbs
  summarise_at(x, vars(!!!dots), list(~ max(., na.rm = TRUE)))
}

fun3(df, "B")
#>          B
#> 1 1.715065

fun3(df, "B", "D")
#>          B        D
#> 1 1.715065 1.786913

Use bare column names

fun4 <- function(x, ...) {
  # capture expressions and create quosures
  dots <- enquos(...)
  # unquote to evaluate inside dplyr verbs
  summarise_at(x, vars(!!!dots), list(~ max(., na.rm = TRUE)))
}

fun4(df, B)
#>          B
#> 1 1.715065

fun4(df, B, D)
#>          B        D
#> 1 1.715065 1.786913

I got this error when I was trying to create a virtualenv with command virtualenv myVirtualEnv. I just added a sudo before the command; it solved everything.

I am also new to MVC and I received the same error and found that it is not passing proper routeValues in the Index view or whatever view is present to view the all data.

It was as below

<td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>

I changed it to the as show below and started to work properly.

<td>
            @Html.ActionLink("Edit", "Edit", new { EmployeeID=item.EmployeeID }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>

Basically this error can also come because of improper navigation also.

I think because C would be seen the C drive on the client pc, it wont let you. And if it could do this, it would be a big security hole.

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

A good way of going about this is not to use nargin, but to check whether the variables have been set using exist('opt', 'var').

Example:

function [a] = train(x, y, opt)
    if (~exist('opt', 'var'))
        opt = true;
    end
end

See this answer for pros of doing it this way: How to check whether an argument is supplied in function call?

Note:
to remove, delete, or uninstall nvm - just remove the $NVM_DIR folder (usually ~/.nvm)
you can try :
rm -rf ~/.nvm

I'd probably go with this (I know its not pure linq), keep a reference to the original list if you want to retain all items, and you should find the updated values are in there:

 foreach (var mc in list.Where(x => x.Name == "height"))  
     mc.Value = 30;

Maybe is late now but following Spacedman, did you try duplicate="strip" or any other option?

x=runif(1000)
y=runif(1000)
z=rnorm(1000)
s=interp(x,y,z,duplicate="strip")
surface3d(s$x,s$y,s$z,color="blue")
points3d(s)

dat <- dat[-1, ] worked but it killed my dataframe, changing it into another type. Had to instead use dat <- data.frame(dat[-1, ]) but this is possibly a special case as this dataframe initially had only one column.

Alternative syntax:

INSERT tbl (Col1, Col2, ..., ColN)
  SELECT Col1, Col2, ..., ColN
  FROM Tbl2
  WHERE ...

The select query can (of course) include expressions, case statements, constants/literals, etc.

You can.

Extending @marcg 's UtilException and adding generic <E extends Exception> where necessary: this way, the compiler will force you again to add throw clauses and everything's as if you could throw checked exceptions natively on java 8's streams.

public final class LambdaExceptionUtil {

    @FunctionalInterface
    public interface Function_WithExceptions<T, R, E extends Exception> {

    public static <T, R, E extends Exception> Function<T, R> rethrowFunction(Function_WithExceptions<T, R, E> function) throws E  {
        return t -> {
            try {
                return function.apply(t);
            } catch (Exception exception) {
                throwActualException(exception);
                return null;
            }
        };
    }

    private static <E extends Exception> void throwActualException(Exception exception) throws E {
        throw (E) exception;
    }

}

    @Test
    public void testFunction() throws MyTestException {
        List<Integer> sizes = Stream.of("ciao", "hello").<Integer>map(rethrowFunction(s -> transform(s))).collect(toList());
        assertEquals(2, sizes.size());
        assertEquals(4, sizes.get(0).intValue());
        assertEquals(5, sizes.get(1).intValue());
    }

    private Integer transform(String value) throws MyTestException {
        if(value==null) {
            throw new MyTestException();
        }
        return value.length();
    }

    private static class MyTestException extends Exception { }
}

In dynamic languages, when the interpreter imports, it simply reads a file and evaluates it.

In C, external libraries are located by the linker at compile time to build the final object if the library is statically compiled, while for dynamic libraries a smaller version of the linker is called at runtime which remaps addresses and so makes code in the library available to the executable.

In Java, import is simply used by the compiler to let you name your classes by their unqualified name, let's say String instead of java.lang.String. You don't really need to import java.lang.* because the compiler does it by default. However this mechanism is just to save you some typing. Types in Java are fully qualified class names, so a String is really a java.lang.String object when the code is run. Packages are intended to prevent name clashes and allow two classes to have the same simple name, instead of relying on the old C convention of prefixing types like this. java_lang_String. This is called namespacing.

BTW, in Java there's the static import construct, which allows to further save typing if you use lots of constants from a certain class. In a compilation unit (a .java file) which declares

import static java.lang.Math.*;

you can use the constant PI in your code, instead of referencing it through Math.PI, and the method cos() instead of Math.cos(). So for example you can write

double r = cos(PI * theta);

Once you understand that classes are always referenced by their fully qualified name in the final bytecode, you must understand how the class code is actually loaded. This happens the first time an object of that class is created, or the first time a static member of the class is accessed. At this time, the ClassLoader tries to locate the class and instantiate it. If it can't find the class a NoClassDefFoundError is thrown (or a a ClassNotFoundException if the class is searched programmatically). To locate the class, the ClassLoader usually checks the paths listed in the $CLASSPATH environment variable.

To solve your problem, it seems you need an applet element like this

<applet
  codebase = "http://san.redenetimoveis.com"
  archive="test.jar, core.jar"
  code="com.colorfulwolf.webcamapplet.WebcamApplet"      
  width="550" height="550" >

BTW, you don't need to import the archives in the standard JRE.

It’s very simple, it just advertises a string which contains a few characters conforming to Apple’s iBeacon standard. you can refer the Link http://glimwormbeacons.com/learn/what-makes-an-ibeacon-an-ibeacon/

Obviously this issue has different causes. :)

For my case, my account log in expired... I solved it by simply:

XCode -> Preferences -> Account -> Apple IDs -> Select the related ID and renew the log in...

Hope this helps!

In general, you're looking for the "Except" extension.

var rejectStatus = GenerateRejectStatuses();
var fullList = GenerateFullList();
var rejectList = fullList.Where(i => rejectStatus.Contains(i.Status));
var filteredList = fullList.Except(rejectList);

In this example, GenerateRegectStatuses() should be the list of statuses you wish to reject (or in more concrete terms based on your example, a List<int> of IDs)

Here is the solution to convert the string to valid plain or decimal numbers using Regex:

//something123.777.321something to 123.777321
const str = 'something123.777.321something';
let initialValue = str.replace(/[^0-9.]+/, '');
//initialValue = '123.777.321';

//characterCount just count the characters in a given string
if (characterCount(intitialValue, '.') > 1) {
 const splitedValue = intitialValue.split('.');
 //splittedValue = ['123','777','321'];
 intitialValue = splitedValue.shift() + '.' + splitedValue.join('');
 //result i.e. initialValue = '123.777321'
}

Even though this is an old question, I've just come across the problem and solved it differently from the given answers. Maybe it could be helpful to others.

I noticed that even though my XML files looked like:

<tag>
 <subTag>content with newline.\r\nto display</subTag>
</tag>

When it was read into my C# code the string had double backslashes.

\\r\\n

To fix this I wrote a ValueConverter to strip the extra backslash.

public class XmlStringConverter : IValueConverter
{
    public object Convert(
        object value,
        Type targetType,
        object parameter,
        CultureInfo culture)
    {
        string valueAsString = value as string;
        if (string.IsNullOrEmpty(valueAsString))
        {
            return value;
        }

        valueAsString = valueAsString.Replace("\\r\\n", "\r\n");
        return valueAsString;
    }

    public object ConvertBack(
        object value,
        Type targetType,
        object parameter,
        CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

With ECMA script 2017 (supported by Node 7.6 and above), it becomes a one-liner:

function sleep(millis) {
  return new Promise(resolve => setTimeout(resolve, millis));
}

// Usage in async function
async function test() {
  await sleep(1000)
  console.log("one second has elapsed")
}

// Usage in normal function
function test2() {
  sleep(1000).then(() => {
    console.log("one second has elapsed")
  });
}

I might be missing something in your question here... but from what I can gather, by using the subtract method this should be what you're looking to do:

var timeStr = "00:03:15";
    timeStr = timeStr.split(':');

var h = timeStr[1],
    m = timeStr[2];

var newTime = moment("01:20:00 06-26-2014")

I used placeholders so just follow along, as you might want to still keep the inheritance from the original style.

Before

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{originalBaseStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

After:

styles.xml

<style name="{{yourToolbarStyle}}" parent="{{originalBaseStyle}}">
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <item name="actionMenuTextColor">@android:color/white</item>
    <item name="actionOverflowButtonStyle">@style/ActionButtonOverflowStyle</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

Therefore

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{yourToolbarStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

DO NOT USE self::, use static::

There is another aspect of self:: that is worth mentioning. Annoyingly self:: refers to the scope at the point of definition not at the point of execution. Consider this simple class with two methods:

class Person
{

    public static function status()
    {
        self::getStatus();
    }

    protected static function getStatus()
    {
        echo "Person is alive";
    }

}

If we call Person::status() we will see "Person is alive" . Now consider what happens when we make a class that inherits from this:

class Deceased extends Person
{

    protected static function getStatus()
    {
        echo "Person is deceased";
    }

}

Calling Deceased::status() we would expect to see "Person is deceased" however what we see is "Person is alive" as the scope contains the original method definition when call to self::getStatus() was defined.

PHP 5.3 has a solution. the static:: resolution operator implements "late static binding" which is a fancy way of saying that it's bound to the scope of the class called. Change the line in status() to static::getStatus() and the results are what you would expect. In older versions of PHP you will have to find a kludge to do this.

See PHP Documentation

So to answer the question not as asked ...

$this-> refers to the current object (an instance of a class), whereas static:: refers to a class

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

Press the start button in visual studio. Then go to the location where your solution is stored and open the folder of your main project then the bin folder. If your application was running in debug mode then go to the debug folder. If running in release mode then go to the release folder. You should find your exe there.

SELECT name FROM sqlite_master where name = '<TABLE_NAME_HERE>'

If the table name does not exist then there would not be any records returned!

You can as well use

SELECT count(name) FROM sqlite_master where name = '<TABLE_NAME_HERE>' 

if the count is 1, means table exists, otherwise, it would return 0

Hardware -> Erase all content and settings did the job for me (other things didn't).

PDT eclipse from ZEND has a mac version (PDT all-in-one).

I've been using it for about 3 months and it's pretty solid and has debugging capabilities with xdebug (debug howto) and zend debugger.

I was facing "java.lang.OutOfMemoryError: Java heap space" error while building my project using maven install command.

I was able to get rid of it by changing maven runner settings.

Settings | Build, Execution, Deployment | Build Tools | Maven | Runner | VM options to -Xmx512m

$('head').append('<meta http-equiv="X-UA-Compatible" content="IE=Edge" />');

or

var meta = document.createElement('meta');
meta.httpEquiv = "X-UA-Compatible";
meta.content = "IE=edge";
document.getElementsByTagName('head')[0].appendChild(meta);

Though I'm not certain it will have an affect as it will be generated after the page is loaded

If you want to add meta data tags for page description, use the SETTINGS of your DNN page to add Description and Keywords. Beyond that, the best way to go when modifying the HEAD is to dynamically inject your code into the HEAD via a third party module.

Found at http://www.dotnetnuke.com/Resources/Forums/forumid/7/threadid/298385/scope/posts.aspx

This may allow other meta tags, if you're lucky

Additional HEAD tags can be placed into Page Settings > Advanced Settings > Page Header Tags.

Found at http://www.dotnetnuke.com/Resources/Forums/forumid/-1/postid/223250/scope/posts.aspx

In head:

  (function() {
    var jsapi = document.createElement('script'); jsapi.type = 'text/javascript'; jsapi.async = true;
    jsapi.src = ('https:' == document.location.protocol ? 'https://' : 'http://') + 'www.google.com/jsapi?key=YOUR KEY';
    (document.getElementsByTagName('head')[0] || document.getElementsByTagName('head')[0]).appendChild(jsapi);
  })();

End of Body:

<script type="text/javascript">
google.load("jquery", "version");
</script>

Create Table:

Create Table EmployeeProfile ( 
    EmpId int, 
    EmpName varchar(50) not null, 
    EmpPhoto varbinary(max) not null ) 
Go

Insert statement:

Insert EmployeeProfile 
   (EmpId, EmpName, EmpPhoto) 
   Select 1001, 'Vadivel', BulkColumn 
   from Openrowset( Bulk 'C:\Image1.jpg', Single_Blob) as EmployeePicture

This Sql Query Working Fine.

You could also do

function insertAfter(node1, node2) {
    node1.outerHTML += node2.outerHTML;
}

or

function insertAfter2(node1, node2) {
    var wrap = document.createElement("div");
    wrap.appendChild(node2.cloneNode(true));
    var node2Html = wrap.innerHTML;
    node1.insertAdjacentHTML('afterend', node2Html);
}

On a fresh Linux machine you also need to install git. Bundle uses it behind the scenes.

echo "Subject: test" | /usr/sbin/sendmail [email protected]

This enables you to do it within one command line without having to echo a text file. This answer builds on top of @mti2935's answer. So credit goes there.

In my case the "Fix Issue" button triggers a spinner for about 20 seconds and fixes nothing.

This works for me (iOS 7 iPhone 5, Xcode 5):

Xcode > Window > Organizer > Devices

Find the connected device(with a green dot) on the left pane. Select "Provisioning Profiles" On the right pane, there is a line with warning. Delete this line.

Now go back to click the "Fix Issue" button and everything is fine - the app runs in the device as expected.

I know it's been a while, but I'll this here in case it helps someone out.

The right answer by far is (and the selected one) the one from CommonsWare. I was having the same problem as posted, the following

MyFragmentClass fragmentList = 
            (MyFragmentClass) getSupportFragmentManager().findFragmentById(R.id.fragementID);

kept on returning null. My mistake was really silly, in my xml file:

<fragment
    android:tag="@+id/fragementID"
    android:name="com.sf.lidgit_android.content.MyFragmentClass"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
/>

The mistake was that I had android:tag INSTEAD OF android:id.

Depending on your table type, locking will perform differently, but so will a SELECT count. For MyISAM tables a simple SELECT count(*) FROM table should not lock the table since it accesses meta data to pull the record count. Innodb will take longer since it has to grab the table in a snapshot to count the records, but it shouldn't cause locking.

You should at least have concurrent_insert set to 1 (default). Then, if there are no "gaps" in the data file for the table to fill, inserts will be appended to the file and SELECT and INSERTs can happen simultaneously with MyISAM tables. Note that deleting a record puts a "gap" in the data file which will attempt to be filled with future inserts and updates.

If you rarely delete records, then you can set concurrent_insert equal to 2, and inserts will always be added to the end of the data file. Then selects and inserts can happen simultaneously, but your data file will never get smaller, no matter how many records you delete (except all records).

The bottom line, if you have a lot of updates, inserts and selects on a table, you should make it InnoDB. You can freely mix table types in a system though.

A lot of answers above have fields compared in single comparator method which is not actually working. There are some answers though with different comparators implemented for each field, I am posting this because this example would be much more clearer and simple to understand I am believing.

class Student{
    Integer bornYear;
    Integer bornMonth;
    Integer bornDay;
    public Student(int bornYear, int bornMonth, int bornDay) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;
        this.bornDay = bornDay;
    }
    public Student(int bornYear, int bornMonth) {

        this.bornYear = bornYear;
        this.bornMonth = bornMonth;

    }
    public Student(int bornYear) {

        this.bornYear = bornYear;

    }
    public Integer getBornYear() {
        return bornYear;
    }
    public void setBornYear(int bornYear) {
        this.bornYear = bornYear;
    }
    public Integer getBornMonth() {
        return bornMonth;
    }
    public void setBornMonth(int bornMonth) {
        this.bornMonth = bornMonth;
    }
    public Integer getBornDay() {
        return bornDay;
    }
    public void setBornDay(int bornDay) {
        this.bornDay = bornDay;
    }

Here a simple example for a function to load JS files. Relevant points:

• you don't need jQuery, so you may use this initially to load also the jQuery.js file
• it is async with callback
• it ensures it loads only once, as it keeps an enclosure with the record of loaded urls, thus avoiding usage of network
• contrary to jQuery $.ajax or $.getScript you can use nonces, solving thus issues with CSP unsafe-inline. Just use the property script.nonce

var getScriptOnce = function() {

    var scriptArray = []; //array of urls (closure)

    //function to defer loading of script
    return function (url, callback){
        //the array doesn't have such url
        if (scriptArray.indexOf(url) === -1){

            var script=document.createElement('script');
            script.src=url;
            var head=document.getElementsByTagName('head')[0],
                done=false;

            script.onload=script.onreadystatechange = function(){
                if ( !done && (!this.readyState || this.readyState == 'loaded' || this.readyState == 'complete') ) {
                    done=true;
                    if (typeof callback === 'function') {
                        callback();
                    }
                    script.onload = script.onreadystatechange = null;
                    head.removeChild(script);

                    scriptArray.push(url);
                }
            };

            head.appendChild(script);
        }
    };
}();

Now you use it simply by

getScriptOnce("url_of_your_JS_file.js");

Based on @Raghuram answer, I find a tutorial on Copying project dependencies, Just:

1. Open your project pom.xml file and find this:

   <project>
     [...]
     <build>
       <plugins>
         ...
       </plugins>
     </build>
     [...]
   </project>
   

2. Than replace the <plugins> ... </plugins> with:

   <plugins>
     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-dependency-plugin</artifactId>
       <version>3.0.0</version>
       <executions>
         <execution>
           <id>copy-dependencies</id>
           <phase>package</phase>
           <goals>
             <goal>copy-dependencies</goal>
           </goals>
           <configuration>
             <outputDirectory>${project.build.directory}/alternateLocation</outputDirectory>
             <overWriteReleases>false</overWriteReleases>
             <overWriteSnapshots>false</overWriteSnapshots>
             <overWriteIfNewer>true</overWriteIfNewer>
           </configuration>
         </execution>
       </executions>
     </plugin>
   </plugins>
   

3. And call maven within the command line mvn dependency:copy-dependencies

After it finishes, it will create the folder target/dependency within all the jar's dependencies on the current directory where the pom.xml lives.

Don't know why @Janos deleted his answer, but it's correct: your data frame Train doesn't have a column named pre. When you pass a formula and a data frame to a model-fitting function, the names in the formula have to refer to columns in the data frame. Your Train has columns called residual.sugar, total.sulfur, alcohol and quality. You need to change either your formula or your data frame so they're consistent with each other.

And just to clarify: Pre is an object containing a formula. That formula contains a reference to the variable pre. It's the latter that has to be consistent with the data frame.

If your code doesn't cross filesystem boundaries, i.e. you're just working with one filesystem, then use java.io.File.separator.

This will, as explained, get you the default separator for your FS. As Bringer128 explained, System.getProperty("file.separator") can be overriden via command line options and isn't as type safe as java.io.File.separator.

The last one, java.nio.file.FileSystems.getDefault().getSeparator(); was introduced in Java 7, so you might as well ignore it for now if you want your code to be portable across older Java versions.

So, every one of these options is almost the same as others, but not quite. Choose one that suits your needs.

I will add a StackBlitz example and a comment to the answer from @tahiche.

The return value is a function to remove the event listener after you have added it. It is considered good practice to remove event listeners when you don't need them anymore. So you can store this return value and call it inside your ngOnDestroy method.

I admit that it might seem confusing at first, but it is actually a very useful feature. How else can you clean up after yourself?

export class MyComponent implements OnInit, OnDestroy {

  public removeEventListener: () => void;

  constructor(
    private renderer: Renderer2, 
    private elementRef: ElementRef
  ) {
  }

  public ngOnInit() {
    this.removeEventListener = this.renderer.listen(this.elementRef.nativeElement, 'click', (event) => {
      if (event.target instanceof HTMLAnchorElement) {
        // Prevent opening anchors the default way
        event.preventDefault();
        // Your custom anchor click event handler
        this.handleAnchorClick(event);
      }
    });
  }

  public ngOnDestroy() {
    this.removeEventListener();
  }
}

You can find a StackBlitz here to show how this could work for catching clicking on anchor elements.

I added a body with an image as follows:
<img src="x" onerror="alert(1)"></div>
to show that the sanitizer is doing its job.

Here in this fiddle you find the same body attached to an innerHTML without sanitizing it and it will demonstrate the issue.

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

Like biegleux already said:

• small represents 14sp
• medium represents 18sp
• large represents 22sp

If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml file in your values folder and define the text size there with the following 3 lines:

<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>

Here is an example for a TextView with large text from the dimens.xml file:

<TextView
  android:id="@+id/hello_world"
  android:text="hello world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textSize="@dimen/text_size_large"/>

On Ubuntu, you'll need to install unixodbc-dev:

sudo apt-get install unixodbc-dev

Install pip by using this command:

sudo apt-get install python-pip

once that is installed, you should be able to install pyodbc successfully:

pip install pyodbc

Firstly create app.js file in the directory you want to publish.

var http = require('http');
var fs = require('fs');
var mime = require('mime');
http.createServer(function(req,res){
    if (req.url != '/app.js') {
    var url = __dirname + req.url;
        fs.stat(url,function(err,stat){
            if (err) {
            res.writeHead(404,{'Content-Type':'text/html'});
            res.end('Your requested URI('+req.url+') wasn\'t found on our server');
            } else {
            var type = mime.getType(url);
            var fileSize = stat.size;
            var range = req.headers.range;
                if (range) {
                    var parts = range.replace(/bytes=/, "").split("-");
                var start = parseInt(parts[0], 10);
                    var end = parts[1] ? parseInt(parts[1], 10) : fileSize-1;
                    var chunksize = (end-start)+1;
                    var file = fs.createReadStream(url, {start, end});
                    var head = {
                'Content-Range': `bytes ${start}-${end}/${fileSize}`,
                'Accept-Ranges': 'bytes',
                'Content-Length': chunksize,
                'Content-Type': type
                }
                    res.writeHead(206, head);
                    file.pipe(res);
                    } else {    
                    var head = {
                'Content-Length': fileSize,
                'Content-Type': type
                    }
                res.writeHead(200, head);
                fs.createReadStream(url).pipe(res);
                    }
            }
        });
    } else {
    res.writeHead(403,{'Content-Type':'text/html'});
    res.end('Sorry, access to that file is Forbidden');
    }
}).listen(8080);

You don't need to call json.getJSONArray() at all, because the JSON you're working with already is an array. So, don't construct an instance of JSONObject; use a JSONArray. This should suffice:

// ...
JSONArray json = new JSONArray(result);
// ...

for(int i=0;i<json.length();i++){                        
    HashMap<String, String> map = new HashMap<String, String>();    
    JSONObject e = json.getJSONObject(i);

    map.put("id",  String.valueOf(i));
    map.put("name", "Earthquake name:" + e.getString("eqid"));
    map.put("magnitude", "Magnitude: " +  e.getString("magnitude"));
    mylist.add(map);            
}

You can't use exactly the same methods as in the tutorial, because the JSON you're dealing with needs to be parsed into a JSONArray at the root, not a JSONObject.

The issue has been resolved while installation of the maven settings is provided as External in Eclipse. The navigation settings are Window --> Preferences --> Installations. Select the External as installation Type, provide the Installation home and name and click on Finish. Finally select this as default installations.

Giving width to Label is not a proper way. you should take one div or table structure to manage this. but still if you don't want to change your whole code then you can use following code.

label {
  width:200px;
  float: left;
}

Saudate, I ran across this looking for a different problem. You most definitely can use the Sql Server Import wizard to import data into a new table. Of course, you do not wish to leave that table in the database, so my suggesting is that you import into a new table, then script the data in query manager to insert into the existing table. You can add a line to drop the temp table created by the import wizard as the last step upon successful completion of the script.

I believe your original issue is in fact related to Sql Server 64 bit and is due to your having a 32 bit Excel and these drivers don't play well together. I did run into a very similar issue when first using 64 bit excel.

In order to comply with boneheaded precedent, getYear() returns the number of years since 1900.

Instead, you should call getFullYear(), which returns the actual year.

I'am using VisualStdio 2008. In this case I often set Preprocessor Definitions

Menu \ Project \ [ProjectName] Properties... Alt+F7

If click this menu or press Alt + F7 in project window, you can see "Property Pages" window.

Then see menu on left of window.

Configuration Properties \ C/C++ \ Preprocessor

Then add _CRT_SECURE_NO_WARNINGS to \ Preprocessor Definitions.

Since header files from some C libraries use the keyword, the C++ language will have to do something about it.. at the minimum, ignoring the keyword, so we don't have to #define the keyword to a blank macro to suppress the keyword.

using (SqlConnection connection =  new SqlConnection("Data Source=localhost;Initial Catalog=LoginScreen;Integrated Security=True"))
{
    SqlCommand command =
    new SqlCommand("select * from Pending_Tasks WHERE CustomerId=...", connection);
    connection.Open();

    SqlDataReader read= command.ExecuteReader();

    while (read.Read())
    {
        CustID.Text = (read["Customer_ID"].ToString());
        CustName.Text = (read["Customer_Name"].ToString());
        Add1.Text = (read["Address_1"].ToString());
        Add2.Text = (read["Address_2"].ToString());
        PostBox.Text = (read["Postcode"].ToString());

        MobNumber.Text = (read["Mobile"].ToString());
        FaultRep.Text = (read["Fault_Report"].ToString());
    }
    read.Close();

Make sure you have data in the query : select * from Pending_Tasks and you are using "using System.Data.SqlClient;"

The present solution produces the same flow as your OP. It does not use Labels, but this was not a requirement of the OP. You only asked for "a simple conditional loop that will go to the next iteration if a condition is true", and since this is cleaner to read, it is likely a better option than that using a Label.

What you want inside your for loop follows the pattern

If (your condition) Then
    'Do something
End If

In this case, your condition is Not(Return = 0 And Level = 0), so you would use

For i = 2 To 24
    Level = Cells(i, 4)
    Return = Cells(i, 5)

    If (Not(Return = 0 And Level = 0)) Then
        'Do something
    End If
Next i

PS: the condition is equivalent to (Return <> 0 Or Level <> 0)

You are comparing a with a property of a.

a is of type Answer. a.Correct, I'm guessing is a boolean.

Short form:-

Answer = answer.SingleOrDefault(a => a.Correct);

According to Martin Fowler a POJO is an object which encapsulates Business Logic while a Bean (except for the definition already stated in other answers) is little more than a container for holding data and the operations available on the object merely set and get data.

The term was coined while Rebecca Parsons, Josh MacKenzie and I were preparing for a talk at a conference in September 2000. In the talk we were pointing out the many benefits of encoding business logic into regular java objects rather than using Entity Beans. We wondered why people were so against using regular objects in their systems and concluded that it was because simple objects lacked a fancy name. So we gave them one, and it's caught on very nicely.

If you using Ubuntu, So firstly you have unhide all files from your home directory or where located your android studio folder :

1. Go to your home directory and unhide all files by using ctrl+h
2. You found .gradle folder
3. Inside .gradle -> wrapper
4. You can found dists folder, So delete this dists folder
5. Create a New Project than your Gradle file re-downloaded
6. Congo you successfully build project

Sometimes it is not eligible to set height to pixel values. However, it is possible to show vertical scrollbar through setting height of div to 100% and overflow to auto.

Let me show an example:

<div id="content" style="height: 100%; overflow: auto">
  <p>some text</p>
  <ul>
    <li>text</li>
    .....
    <li>text</li>
</div>

Another point to take in consideration is that the new UI for Service Interface will give you much more flexibility on how you want to create your proxy class. For example, it will allow you to map data contracts to existing dlls, if they match (actually this is the default behaviour).

I am working on DOM Keyboard Event Level 3 polyfill . In latest browsers or with this polyfill you can do something like this:

element.addEventListener("keydown", function(e){ console.log(e.key, e.char, e.keyCode) })

var e = new KeyboardEvent("keydown", {bubbles : true, cancelable : true, key : "Q", char : "Q", shiftKey : true});
element.dispatchEvent(e);

//If you need legacy property "keyCode"
// Note: In some browsers you can't overwrite "keyCode" property. (At least in Safari)
delete e.keyCode;
Object.defineProperty(e, "keyCode", {"value" : 666})

UPDATE:

Now my polyfill supports legacy properties "keyCode", "charCode" and "which"

var e = new KeyboardEvent("keydown", {
    bubbles : true,
    cancelable : true,
    char : "Q",
    key : "q",
    shiftKey : true,
    keyCode : 81
});

Examples here

Additionally here is cross-browser initKeyboardEvent separately from my polyfill: (gist)

Polyfill demo

bool EndsWith(const std::string& data, const std::string& suffix)

You can use PdfBox from Apache which is simple to use and has good performance.

Here is an example of extracting text from a PDF file (you can read more here) :

import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.util.*;

public class PDFTest {

 public static void main(String[] args){
 PDDocument pd;
 BufferedWriter wr;
 try {
         File input = new File("C:\\Invoice.pdf");  // The PDF file from where you would like to extract
         File output = new File("C:\\SampleText.txt"); // The text file where you are going to store the extracted data
         pd = PDDocument.load(input);
         System.out.println(pd.getNumberOfPages());
         System.out.println(pd.isEncrypted());
         pd.save("CopyOfInvoice.pdf"); // Creates a copy called "CopyOfInvoice.pdf"
         PDFTextStripper stripper = new PDFTextStripper();
         wr = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(output)));
         stripper.writeText(pd, wr);
         if (pd != null) {
             pd.close();
         }
        // I use close() to flush the stream.
        wr.close();
 } catch (Exception e){
         e.printStackTrace();
        } 
     }
}

UPDATE:

You can get the text using PDFTextStripper:

PDFTextStripper reader = new PDFTextStripper();
String pageText = reader.getText(pd); // PDDocument object created

You can use this comment in jsp page

 <%--your comment --%>

Second way of comment declaration in jsp page you can use the comment of two typ in jsp code

 single line comment
 <% your code //your comment%>

multiple line comment 

<% your code 
/**
your another comment
**/

%>

And you can also comment on jsp page from html code for example:

<!-- your commment -->

I have created my own git alias to do exactly this. I'm calling it git freebase! It will take your existing messy, unrebasable feature branch and recreate it so that it becomes a new branch with the same name with its commits squashed into one commit and rebased onto the branch you specify (master by default). At the very end, it will allow you to use whatever commit message you like for your newly "freebased" branch.

Install it by placing the following alias in your .gitconfig:

[alias]
  freebase = "!f() { \
    TOPIC="$(git branch | grep '\\*' | cut -d ' ' -f2)"; \
    NEWBASE="${1:-master}"; \
    PREVSHA1="$(git rev-parse HEAD)"; \
    echo "Freebaseing $TOPIC onto $NEWBASE, previous sha1 was $PREVSHA1"; \
    echo "---"; \
    git reset --hard "$NEWBASE"; \
    git merge --squash "$PREVSHA1"; \
    git commit; \
  }; f"

Use it from your feature branch by running: git freebase <new-base>

I've only tested this a few times, so read it first and make sure you want to run it. As a little safety measure it does print the starting sha1 so you should be able to restore your old branch if anything goes wrong.

I'll be maintaining it in my dotfiles repo on github: https://github.com/stevecrozz/dotfiles/blob/master/.gitconfig

So, I checked Windows Features to make sure I didn't have this thing called WebDAV installed, and it said I didn't. Anyways, I went ahead and placed the following in my web.config (both front end and WebAPI, just to be sure), and it works now. I placed this inside <system.webServer>.

<modules runAllManagedModulesForAllRequests="true">
    <remove name="WebDAVModule"/> <!-- add this -->
</modules>

Additionally, it is often required to add the following to web.config in the handlers. Thanks to Babak

<handlers>
    <remove name="WebDAV" />
    ...
</handlers>

document.write(`<td width='74'><button id='button' type='button' onclick='myfunction(\``+ name + `\`)'>click</button></td>`)

Better to use `` than "". This is a more dynamic answer.

I would do it with cssSelector:

// for all checked checkboxes
driver.findElements(By.cssSelector("input:checked[type='checkbox']"));
// for all notchecked checkboxes
driver.findElements(By.cssSelector("input:not(:checked)[type='checkbox']"));

Maybe that also helps ;-)

Well it has a simple and easy solution. You can make your video easily to fit for any device and screen size. Here is the HTML and CSS code:

 padding-top:30px;_x000D_
 height:0;_x000D_
 overflow:hidden;_x000D_
}_x000D_
_x000D_
.yt-container iframe, .yt-container object, .yt-container embed {_x000D_

Check the daemon option in nginx.conf file. It has to be ON. Or you can simply rip out this line from config file. This option is fully described here http://nginx.org/en/docs/ngx_core_module.html#daemon

Try out this package, Jiffy, it also runs on top of Intl, but makes it easier using momentjs syntax. See below

import 'package:jiffy/jiffy.dart';   

var now = Jiffy().format("yyyy-MM-dd HH:mm:ss");

You can also do the following

var a = Jiffy().yMMMMd; // October 18, 2019

And you can also pass in your DateTime object, A string and an array

var a = Jiffy(DateTime(2019, 10, 18)).yMMMMd; // October 18, 2019

var a = Jiffy("2019-10-18").yMMMMd; // October 18, 2019

var a = Jiffy([2019, 10, 18]).yMMMMd; // October 18, 2019

Once you have selected the highest value, which is "12" in my example, you can then declare it as integer and increment your value:

$FileList = "1", "2", "11"
$foldername = [int]$FileList[2] + 1
$foldername

Do you have a bean declared in your context file that has an id of "articleService"? I believe that autowiring matches the id of a bean in your context files with the variable name that you are attempting to Autowire.

public class SubSubClass extends SubClass {

    @Override
    public void print() {
        super.superPrint();
    }

    public static void main(String[] args) {
        new SubSubClass().print();
    }
}

class SuperClass {

    public void print() {
        System.out.println("Printed in the GrandDad");
    }
}

class SubClass extends SuperClass {

    public void superPrint() {
        super.print();
    }
}

Output: Printed in the GrandDad

As a follow-up to Adam Matan's answer, the /proc/<pid> directory's time stamp as such is not necessarily directly useful, but you can use

awk -v RS=')' 'END{print $20}' /proc/12345/stat

to get the start time in clock ticks since system boot.¹

This is a slightly tricky unit to use; see also convert jiffies to seconds for details.

awk -v ticks="$(getconf CLK_TCK)" 'NR==1 { now=$1; next }
    END { printf "%9.0f\n", now - ($20/ticks) }' /proc/uptime RS=')' /proc/12345/stat

This should give you seconds, which you can pass to strftime() to get a (human-readable, or otherwise) timestamp.

awk -v ticks="$(getconf CLK_TCK)" 'NR==1 { now=$1; next }
    END { print strftime("%c", systime() - (now-($20/ticks))) }' /proc/uptime RS=')' /proc/12345/stat

Updated with some fixes from Stephane Chazelas in the comments; thanks as always!

If you only have Mawk, maybe try

awk -v ticks="$(getconf CLK_TCK)" -v epoch="$(date +%s)" '
  NR==1 { now=$1; next }
  END { printf "%9.0f\n", epoch - (now-($20/ticks)) }' /proc/uptime RS=')' /proc/12345/stat |
xargs -i date -d @{}

¹ man proc; search for starttime.

If getting this error while performing a backup, max_allowed_packet can be set in the my.cnf particularly for mysqldump.

[mysqldump]
max_allowed_packet=512M

I kept getting this error while performing a mysqldump and I did not understand because I had this set in my.cnf under the [mysqld] section. Once I figured out I could set it for [mysqldump] and I set the value, my backups completed without issue.

For Jackson versions < 2.0 use this annotation on the class being serialized:

@JsonSerialize(include=JsonSerialize.Inclusion.NON_NULL)

How about using the C++ language itself?

bool t = true;
bool f = false;
std::cout << std::noboolalpha << t << " == " << std::boolalpha << t << std::endl;        
std::cout << std::noboolalpha << f << " == " << std::boolalpha << f << std::endl;

UPDATE:

If you want more than 4 lines of code without any console output, please go to cppreference.com's page talking about std::boolalpha and std::noboolalpha which shows you the console output and explains more about the API.

Additionally using std::boolalpha will modify the global state of std::cout, you may want to restore the original behavior go here for more info on restoring the state of std::cout.

Add the following code before you instantiate your web service client:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

Or for backward compatibility with TLS 1.1 and prior:

System.Net.ServicePointManager.SecurityProtocol |= SecurityProtocolType.Tls12; 

SHOULD be unique does not mean MUST be unique. However, as stated, some parsers would fail and others would just use the last value parsed. However, if the spec was cleaned up a little to allow for duplicates then I could see a use where you may have an event handler which is transforming the JSON to HTML or some other format... In such cases it would be perfectly valid to parse the JSON and create another document format...

[
  "div":
  {
    "p": "hello",
    "p": "universe"
  },
  "div":
  {
    "h1": "Heading 1",
    "p": "another paragraph"
  }
]

could then easily parse to html for example:

<body>
 <div>
  <p>hello</p>
  <p>universe</p>
 </div>
 <div>
  <h1>Heading 1</h1>
  <p>another paragraph</p>
 </div>
</body>

I can see the reasoning behind the question but as it stands... I wouldn't trust it.

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

It looks like people answered the first part of your question (use application/json).

For the second part: It is perfectly legal to send query parameters in a HTTP POST Request.

Example:

POST /members?id=1234 HTTP/1.1
Host: www.example.com
Content-Type: application/json

{"email":"[email protected]"}

Query parameters are commonly used in a POST request to refer to an existing resource. The above example would update the email address of an existing member with the id of 1234.

It is BAD habit and terribly ANNOYING practice to quote Joshua Bloch without understanding the basic ground-zero fundamentalism.

I have not read anything Joshua Bloch, so either

• he is a terrible programmer
• or the people so far whom I find quoting him (Joshua is the name of a boy I presume) are simply using his material as religious scripts to justify their software religious indulgences.

As in Bible fundamentalism all the biblical laws can be summed up by

• Love the Fundamental Identity with all your heart and all your mind
• Love your neighbour as yourself

and so similarly software engineering fundamentalism can be summed up by

• devote yourself to the ground-zero fundamentals with all your programming might and mind
• and devote towards the excellence of your fellow-programmers as you would for yourself.

Also, among biblical fundamentalist circles a strong and reasonable corollary is drawn

• First love yourself. Because if you don't love yourself much, then the concept "love your neighbour as yourself" doesn't carry much weight, since "how much you love yourself" is the datum line above which you would love others.

Similarly, if you do not respect yourself as a programmer and just accept the pronouncements and prophecies of some programming guru-nath WITHOUT questioning the fundamentals, your quotations and reliance on Joshua Bloch (and the like) is meaningless. And therefore, you would actually have no respect for your fellow-programmers.

The fundamental laws of software programming

• laziness is the virtue of a good programmer
• you are to make your programming life as easy, as lazy and therefore as effective as possible
• you are to make the consequences and entrails of your programming as easy, as lazy and therefore as effective as possible for your neigbour-programmers who work with you and pick up your programming entrails.

Interface-pattern constants is a bad habit ???

Under what laws of fundamentally effective and responsible programming does this religious edict fall into ?

Just read the wikipedia article on interface-pattern constants (https://en.wikipedia.org/wiki/Constant_interface), and the silly excuses it states against interface-pattern constants.

• Whatif-No IDE? Who on earth as a software programmer would not use an IDE? Most of us are programmers who prefer not to have to prove having macho aescetic survivalisticism thro avoiding the use of an IDE.

  • Also - wait a second proponents of micro-functional programming as a means of not needing an IDE. Wait till you read my explanation on data-model normalization.

• Pollutes the namespace with variables not used within the current scope? It could be proponents of this opinion

  • are not aware of, and the need for, data-model normalization

• Using interfaces for enforcing constants is an abuse of interfaces. Proponents of such have a bad habit of

  • not seeing that "constants" must be treated as contract. And interfaces are used for enforcing or projecting compliance to a contract.

• It is difficult if not impossible to convert interfaces into implemented classes in the future. Hah .... hmmm ... ???

  • Why would you want to engage in such pattern of programming as your persistent livelihood? IOW, why devote yourself to such an AMBIVALENT and bad programming habit ?

Whatever the excuses, there is NO VALID EXCUSE when it comes to FUNDAMENTALLY EFFECTIVE software engineering to delegitimize or generally discourage the use of interface constants.

It doesn't matter what the original intents and mental states of the founding fathers who crafted the United States Constitution were. We could debate the original intents of the founding fathers but all I care is the written statements of the US Constitution. And it is the responsibility of every US citizen to exploit the written literary-fundamentalism, not the unwritten founding-intents, of the US Constitution.

Similarly, I do not care what the "original" intents of the founders of the Java platform and programming language had for the interface. What I care are the effective features the Java specification provides, and I intend to exploit those features to the fullest to help me fulfill the fundamental laws of responsible software programming. I don't care if I am perceived to "violate the intention for interfaces". I don't care what Gosling or someone Bloch says about the "proper way to use Java", unless what they say does not violate my need to EFFECTIVE fulfilling fundamentals.

The Fundamental is Data-Model Normalization

It doesn't matter how your data-model is hosted or transmitted. Whether you use interfaces or enums or whatevernots, relational or no-SQL, if you don't understand the need and process of data-model normalization.

We must first define and normalize the data-model of a set of processes. And when we have a coherent data-model, ONLY then can we use the process flow of its components to define the functional behaviour and process blocks a field or realm of applications. And only then can we define the API of each functional process.

Even the facets of data normalization as proposed by EF Codd is now severely challenged and severely-challenged. e.g. his statement on 1NF has been criticized as ambiguous, misaligned and over-simplified, as is the rest of his statements especially in the advent of modern data services, repo-technology and transmission. IMO, the EF Codd statements should be completely ditched and new set of more mathematically plausible statements be designed.

A glaring flaw of EF Codd's and the cause of its misalignment to effective human comprehension is his belief that humanly perceivable multi-dimensional, mutable-dimension data can be efficiently perceived thro a set of piecemeal 2-dimensional mappings.

The Fundamentals of Data Normalization

What EF Codd failed to express.

Within each coherent data-model, these are the sequential graduated order of data-model coherence to achieve.

1. The Unity and Identity of data instances.
   • design the granularity of each data component, whereby their granularity is at a level where each instance of a component can be uniquely identified and retrieved.
   • absence of instance aliasing. i.e., no means exist whereby an identification produces more than one instance of a component.
2. Absence of instance crosstalk. There does not exist the necessity to use one or more other instances of a component to contribute to identifying an instance of a component.
3. The unity and identity of data components/dimensions.
   • Presence of component de-aliasing. There must exist one definition whereby a component/dimension can be uniquely identified. Which is the primary definition of a component;
   • where the primary definition will not result in exposing sub-dimensions or member-components that are not part of an intended component;
4. Unique means of component dealiasing. There must exist one, and only one, such component de-aliasing definition for a component.
5. There exists one, and only one, definition interface or contract to identify a parent component in a hierarchical relationship of components.
6. Absence of component crosstalk. There does not exist the necessity to use a member of another component to contribute to the definitive identification of a component.
   • In such a parent-child relationship, the identifying definition of a parent must not depend on part of the set of member components of a child. A member component of a parent's identity must be the complete child identity without resorting to referencing any or all of the children of a child.
7. Preempt bi-modal or multi-modal appearances of a data-model.
   • When there exists two candidate definitions of a component, it is an obvious sign that there exists two different data-models being mixed up as one. That means there is incoherence at the data-model level, or the field level.
   • A field of applications must use one and only one data-model, coherently.
8. Detect and identify component mutation. Unless you have performed statistical component analysis of huge data, you probably do not see, or see the need to treat, component mutation.
   • A data-model may have its some of its components mutate cyclically or gradually.
   • The mode may be member-rotation or transposition-rotation.
   • Member-rotation mutation could be distinct swapping of child components between components. Or where completely new components would have to be defined.
   • Transpositional mutation would manifest as a dimensional-member mutating into an attribute, vice versa.
   • Each mutation cycle must be identified as a distinct data-modal.
9. Versionize each mutation. Such that you can pull out a previous version of the data model, when perhaps the need arise to treat an 8 year old mutation of the data model.

In a field or grid of inter-servicing component-applications, there must be one and only one coherent data-model or exists a means for a data-model/version to identify itself.

Are we still asking if we could use Interface Constants? Really ?

There are data-normalization issues at stake more consequential than this mundane question. IF you don't solve those issues, the confusion that you think interface constants cause is comparatively nothing. Zilch.

From the data-model normalization then you determine the components as variables, as properties, as contract interface constants.

Then you determine which goes into value injection, property configuration placeholding, interfaces, final strings, etc.

If you have to use the excuse of needing to locate a component easier to dictate against interface constants, it means you are in the bad habit of not practicing data-model normalization.

Perhaps you wish to compile the data-model into a vcs release. That you can pull out a distinctly identifiable version of a data-model.

Values defined in interfaces are completely assured to be non-mutable. And shareable. Why load a set of final strings into your class from another class when all you need is that set of constants ??

So why not this to publish a data-model contract? I mean if you can manage and normalize it coherently, why not? ...

public interface CustomerService {
  public interface Label{
    char AssignmentCharacter = ':';
    public interface Address{
      String Street = "Street";
      String Unit= "Unit/Suite";
      String Municipal = "City";
      String County = "County";
      String Provincial = "State";
      String PostalCode = "Zip"
    }

    public interface Person {
      public interface NameParts{
        String Given = "First/Given name"
        String Auxiliary = "Middle initial"
        String Family = "Last name"
      }
    }
  }
}

Now I can reference my apps' contracted labels in a way such as

CustomerService.Label.Address.Street
CustomerService.Label.Person.NameParts.Family

This confuses the contents of the jar file? As a Java programmer I don't care about the structure of the jar.

This presents complexity to osgi-motivated runtime swapping ? Osgi is an extremely efficient means to allow programmers to continue in their bad habits. There are better alternatives than osgi.

Or why not this? There is no leakage of of the private Constants into published contract. All private constants should be grouped into a private interface named "Constants", because I don't want to have to search for constants and I am too lazy to repeatedly type "private final String".

public class PurchaseRequest {
  private interface Constants{
    String INTERESTINGName = "Interesting Name";
    String OFFICIALLanguage = "Official Language"
    int MAXNames = 9;
  }
}

Perhaps even this:

public interface PurchaseOrderConstants {
  public interface Properties{
    default String InterestingName(){
       return something();
    }
    String OFFICIALLanguage = "Official Language"
    int MAXNames = 9;
  }
}

The only issue with interface constants worth considering is when the interface is implemented.

This is not the "original intention" of interfaces? Like I would care about the "original intention" of the founding fathers in crafting the US Constitution, rather than how the Supreme Court would interpret the written letters of the US Constitution ???

After all, I live in the land of the free, the wild and home of the brave. Be brave, be free, be wild - use the interface. If my fellow-programmers refuse to use efficient and lazy means of programming, am I obliged by the golden rule to lessen my programming efficiency to align with theirs? Perhaps I should, but that is not an ideal situation.

For those using sdkman, this helped me.

Use Case:
I was using identifier 8.0.202-amzn
I decided to install Azul Zulu as follows: sdk install java 13.0.2-zulu

Error: And then i got this unbound error.

Solution:
1. Right-click on your project in Eclipse/STS
2. Choose Build Path > Configure Build Path...
3. Under Libraries, remove the JRE Library, for my case 8.0.202-amzn
4. Under Libraries, click on Modulepath > Add Library...
5. Choose JRE System Library, click Next
6. Choose Alternate JRE, click on Installed JREs...
7. Your previous configured value should be there
8. If it is there, edit it, if it is not there, add one
9. Make sure the name is: 13.0.2-zulu
10. And the location(JRE home) is: /Users/jumping_monkey/.sdkman/candidates/java/current
11. Click Apply and close
12. Click Finish
13. Voila!

You will see JRE System Library [13.0.2-zulu] in your Project Explorer and all errors gone

Bravo!

    fun readFileOnInternalStorage(fileKey: String): String {

        try {

Imagine you've thread A and thread B. They are both synchronised on the same object and inside this block there's a global variable they are both updating;

static boolean commonVar = false;
Object lock = new Object;

...

void threadAMethod(){
    ...
    while(commonVar == false){
         synchornized(lock){
              ...
              commonVar = true
         }
    }
}

void threadBMethod(){
    ...
    while(commonVar == true){
         synchornized(lock){
              ...
              commonVar = false
         }
    }
}

So, when thread A enters in the while loop and holds the lock, it does what it has to do and set the commonVar to true. Then thread B comes in, enters in the while loop and since commonVar is true now, it is be able to hold the lock. It does so, executes the synchronised block, and sets commonVar back to false. Now, thread A again gets it's new CPU window, it was about to quit the while loop but thread B has just set it back to false, so the cycle repeats over again. Threads do something (so they're not blocked in the traditional sense) but for pretty much nothing.

It maybe also nice to mention that livelock does not necessarily have to appear here. I'm assuming that the scheduler favours the other thread once the synchronised block finish executing. Most of the time, I think it's a hard-to-hit expectation and depends on many things happening under the hood.

// Put the image file path into this method
public static String getFileToByte(String filePath){
    Bitmap bmp = null;
    ByteArrayOutputStream bos = null;
    byte[] bt = null;
    String encodeString = null;
    try{
        bmp = BitmapFactory.decodeFile(filePath);
        bos = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.JPEG, 100, bos);
        bt = bos.toByteArray();
        encodeString = Base64.encodeToString(bt, Base64.DEFAULT);
    }
    catch (Exception e){
      e.printStackTrace();
    }
    return encodeString;
}

It couldn't be simpler than this:

    public SomeClass Clone () {

        var clonedJson = JsonConvert.SerializeObject (this);

        return JsonConvert.DeserializeObject<SomeClass> (clonedJson);
    }

Just serialize any object to a JSON string and then deserialize it. This will do a deep copy...

On the one hand, throwing exceptions is inherently expensive, because the stack has to be unwound etc.
On the other hand, accessing a value in a dictionary by its key is cheap, because it's a fast, O(1) operation.

BTW: The correct way to do this is to use TryGetValue

obj item;
if(!dict.TryGetValue(name, out item))
    return null;
return item;

This accesses the dictionary only once instead of twice.
If you really want to just return null if the key doesn't exist, the above code can be simplified further:

obj item;
dict.TryGetValue(name, out item);
return item;

This works, because TryGetValue sets item to null if no key with name exists.

   Rect(int x1, int x2, int y1, int y2)

       assert(y1 < y2);
   }

   int x1, x2, y1, y2;

}

//either the rectangles overlap or the edges touch
bool touch(const Rect &r1, const Rect &r2)
{
    return r1.x1 <= r2.x2 && r2.x1 <= r1.x2 &&
           r1.y1 <= r2.y2 && r2.x1 <= r1.y2;

A very useful lib for custom progress bar in android.

In your layout file

<com.lylc.widget.circularprogressbar.example.CircularProgressBar
android:id="@+id/mycustom_progressbar"
.
.
.
 />

and Java file

CircularProgressBar progressBar = (CircularProgressBar) findViewById(R.id.mycustom_progressbar);
progressBar.setTitle("Circular Progress Bar");

I just came up with the same problem since we still use bootstrap 2.3.2.

My solution for this: http://jsfiddle.net/KnuU6/281/

css:

.myCollapse {
    display: none;
}
.myCollapse.in {
    display: block;
}

javascript:

 $("[data-toggle=myCollapse]").click(function( ev ) {
   ev.preventDefault();
   var target;
   if (this.hasAttribute('data-target')) {
 target = $(this.getAttribute('data-target'));
   } else {
 target = $(this.getAttribute('href'));
   };
   target.toggleClass("in");
 });

html:

<table>
  <tr><td><a href="#demo" data-toggle="myCollapse">Click me to toggle next row</a></td></tr>
  <tr class="collapse" id="#demo"><td>You can collapse and expand me.</td></tr>
</table>

If by "hex data" you mean a string of the form

s = "6a48f82d8e828ce82b82"

you can use

i = int(s, 16)

to convert it to an integer and

str(i)

to convert it to a decimal string.

with UnionTable as  
(
    SELECT a.id, a.time FROM dbo.a
    UNION
    SELECT b.id, b.time FROM dbo.b
) SELECT id FROM UnionTable GROUP BY id

If you have a relatively- (or otherwise-) positioned div you can center something inside it with margin:auto

Vertical centering is a bit tricker, but possible.

     error+=1;
 } else {
     $("#output").html("no_match");

I'd just like to add something to this post for asp:button. I've tried clientId and it doesn't seem to work for me:

__doPostBack('<%= btn.ClientID%>', '');

However, getting the UniqueId seems to post back to the server, like below:

__doPostBack('<%= btn.UniqueID%>', '');

This might help someone else in future, hence posting this.

I would not make the primary key of the "info" table a composite of the two values from other tables.

Others can articulate the reasons better, but it feels wrong to have a column that is really made up of two pieces of information. What if you want to sort on the ID from the second table for some reason? What if you want to count the number of times a value from either table is present?

I would always keep these as two distinct columns. You could use a two-column primay key in mysql ...PRIMARY KEY(id_a, id_b)... but I prefer using a two-column unique index, and having an auto-increment primary key field.

Use crosstab() from the tablefunc module.

SELECT * FROM crosstab(
   $$SELECT user_id, user_name, rn, email_address
     FROM  (
        SELECT u.user_id, u.user_name, e.email_address
             , row_number() OVER (PARTITION BY u.user_id
                            ORDER BY e.creation_date DESC NULLS LAST) AS rn
        FROM   usr u
        LEFT   JOIN email_tbl e USING (user_id)
        ) sub
     WHERE  rn < 4
     ORDER  BY user_id
   $$
  , 'VALUES (1),(2),(3)'
   ) AS t (user_id int, user_name text, email1 text, email2 text, email3 text);

I used dollar-quoting for the first parameter, which has no special meaning. It's just convenient if you have to escape single quotes in the query string which is a common case:

• Insert text with single quotes in PostgreSQL

Detailed explanation and instructions here:

• PostgreSQL Crosstab Query

And in particular, for "extra columns":

• Pivot on Multiple Columns using Tablefunc

The special difficulties here are:

• The lack of key names.
  -> We substitute with row_number() in a subquery.

• The varying number of emails.
  -> We limit to a max. of three in the outer SELECT
  and use crosstab() with two parameters, providing a list of possible keys.

Pay attention to NULLS LAST in the ORDER BY.

I think we can modify the UsedRange code from @Readify's answer above to get the last used column even if the starting columns are blank or not.

So this lColumn = ws.UsedRange.Columns.Count modified to

this lColumn = ws.UsedRange.Column + ws.UsedRange.Columns.Count - 1 will give reliable results always

?Sheet1.UsedRange.Column + Sheet1.UsedRange.Columns.Count - 1

Above line Yields 9 in the immediate window.

First you need to find a row with id == 2 then change the name so:

foreach(DataRow dr in table.Rows) // search whole table
{
    if(dr["Product_id"] == 2) // if id==2
    {
        dr["Product_name"] = "cde"; //change the name
        //break; break or not depending on you
    }
}

You could also try these solutions:

table.Rows[1]["Product_name"] = "cde" // not recommended as it selects 2nd row as I know that it has id 2

Or:

DataRow dr = table.Select("Product_id=2").FirstOrDefault(); // finds all rows with id==2 and selects first or null if haven't found any
if(dr != null)
{
    dr["Product_name"] = "cde"; //changes the Product_name
}

I just found Scandinavian Keyboard as a fine solution to this problem. It do also have English and German keyboard, but neither Dutch nor Spanish - but I guess they could be added. And I guess there is other alternatives out there.

$ echo "SECRET_KEY='####'">> .env

To use them, put this on top of your production.py settings file:

import os

env = os.environ.copy()
SECRET_KEY = env['SECRET_KEY']

Publish it to Heroku using this gem: http://github.com/ddollar/heroku-config.git

$ heroku plugins:install git://github.com/ddollar/heroku-config.git
$ heroku config:push

This way you avoid to change virtualenv files.

Just index using you ind_pos

ind_pos = [1,5,7]
print (a[ind_pos]) 
[88 85 16]


In [55]: a = [0,88,26,3,48,85,65,16,97,83,91]

In [56]: import numpy as np

In [57]: arr = np.array(a)

In [58]: ind_pos = [1,5,7]

In [59]: arr[ind_pos]
Out[59]: array([88, 85, 16])

private List<String> DirSearch(string sDir)
{
    List<String> files = new List<String>();
    try
    {
        foreach (string f in Directory.GetFiles(sDir))
        {
            files.Add(f);
        }
        foreach (string d in Directory.GetDirectories(sDir))
        {
            files.AddRange(DirSearch(d));
        }
    }
    catch (System.Exception excpt)
    {
        MessageBox.Show(excpt.Message);
    }

    return files;
}

and if you don't want to load the entire list in memory and avoid blocking you may take a look at the following answer.

It basically tells the program when you encounter an error just continue at the next line.

If you need to be able to remove the BOM from UTF-8 encoded files, you first need to get hold of an editor that is aware of them.

I personally use E Text Editor.

In the bottom right, there are options for character encoding, including the BOM tag. Load your file, deselect Byte Order Marker if it is selected, resave, and it should be done.

Alt text http://oth4.com/encoding.png

E is not free, but there is a free trial, and it is an excellent editor (limited TextMate compatibility).

Based on @Patrick Boos solution but fixing potential problem with intermediate scrollbars.

export function getRelativeCoordinates(event: MouseEvent, referenceElement: HTMLElement) {
  const position = {
    x: event.pageX,
    y: event.pageY,
  };

  const offset = {
    left: referenceElement.offsetLeft,
    top: referenceElement.offsetTop,
  };

  let reference = referenceElement.offsetParent as HTMLElement;

  while (reference) {
    offset.left += reference.offsetLeft;
    offset.top += reference.offsetTop;
    reference = reference.offsetParent as HTMLElement;
  }

  const scrolls = {
    left: 0,
    top: 0,
  };

  reference = event.target as HTMLElement;
  while (reference) {
    scrolls.left += reference.scrollLeft;
    scrolls.top += reference.scrollTop;
    reference = reference.parentElement as HTMLElement;
  }

  return {
    x: position.x + scrolls.left - offset.left,
    y: position.y + scrolls.top - offset.top,
  };
}

EDIT 2020-09-21: Since 3.4.0, Mockito supports mocking static methods, API is still incubating and is likely to change, in particular around stubbing and verification. It requires the mockito-inline artifact. And you don't need to prepare the test or use any specific runner. All you need to do is :

@Test
public void name() {
    try (MockedStatic<LoggerFactory> integerMock = mockStatic(LoggerFactory.class)) {
        final Logger logger = mock(Logger.class);
        integerMock.when(() -> LoggerFactory.getLogger(any(Class.class))).thenReturn(logger);
        new Controller().log();
        verify(logger).warn(any());
    }
}

The two inportant aspect in this code, is that you need to scope when the static mock applies, i.e. within this try block. And you need to call the stubbing and verification api from the MockedStatic object.

@Mick, try to prepare the owner of the static field too, eg :

@PrepareForTest({GoodbyeController.class, LoggerFactory.class})

EDIT1 : I just crafted a small example. First the controller :

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class Controller {
    Logger logger = LoggerFactory.getLogger(Controller.class);

    public void log() { logger.warn("yup"); }
}

Then the test :

import org.junit.Test;
import org.junit.runner.RunWith;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import static org.mockito.Matchers.any;
import static org.mockito.Matchers.anyString;
import static org.mockito.Mockito.verify;
import static org.powermock.api.mockito.PowerMockito.mock;
import static org.powermock.api.mockito.PowerMockito.mockStatic;
import static org.powermock.api.mockito.PowerMockito.when;

@RunWith(PowerMockRunner.class)
@PrepareForTest({Controller.class, LoggerFactory.class})
public class ControllerTest {

    @Test
    public void name() throws Exception {
        mockStatic(LoggerFactory.class);
        Logger logger = mock(Logger.class);
        when(LoggerFactory.getLogger(any(Class.class))).thenReturn(logger);
        
        new Controller().log();
        
        verify(logger).warn(anyString());
    }
}

Note the imports ! Noteworthy libs in the classpath : Mockito, PowerMock, JUnit, logback-core, logback-clasic, slf4j

EDIT2 : As it seems to be a popular question, I'd like to point out that if these log messages are that important and require to be tested, i.e. they are feature / business part of the system then introducing a real dependency that make clear theses logs are features would be a so much better in the whole system design, instead of relying on static code of a standard and technical classes of a logger.

For this matter I would recommend to craft something like= a Reporter class with methods such as reportIncorrectUseOfYAndZForActionX or reportProgressStartedForActionX. This would have the benefit of making the feature visible for anyone reading the code. But it will also help to achieve tests, change the implementations details of this particular feature.

Hence you wouldn't need static mocking tools like PowerMock. In my opinion static code can be fine, but as soon as the test demands to verify or to mock static behavior it is necessary to refactor and introduce clear dependencies.

Your syntax is for table valued function which return a resultset and can be queried like a table. For scalar function do

 select  dbo.fun_functional_score('01091400003') as [er]

By default in Eclipse you only have to press Ctrl-space for autocomplete. Then select the desired method and wait 500ms for the javadoc info to pop up. If this doesn't work go to the Eclipse Windows menu -> Preferences -> Java -> Editor -> Content assist and check your settings here

PHP and MySQL have their own default timezone configurations. You should synchronize time between your data base and web application, otherwise you could run some issues.

This how I managed to get the screen width in React JS Project:

If width is equal to 1680 then return 570 else return 200

var screenWidth = window.screen.availWidth;

<Label style={{ width: screenWidth == "1680" ? 570 : 200, color: "transparent" }}>a  </Label>

Screen.availWidth

So you need to use what we call promise. Read how angular handles it here, https://docs.angularjs.org/api/ng/service/$q. Turns our $http support promises inherently so in your case we'll do something like this,

(function() {
  "use strict";
  var serviceCallJson = function($http) {

      this.getCustomers = function() {
        // http method anyways returns promise so you can catch it in calling function
        return $http({
            method : 'get',
            url : '../viewersData/userPwdPair.json'
          });
      }

  }

  var validateIn = function (serviceCallJson, $q) {

      this.called = function(username, password) {
          var deferred = $q.defer(); 
          serviceCallJson.getCustomers().then( 
            function( returnedData ) {
              console.log(returnedData); // you should get output here this is a success handler
              var i = 0;
              angular.forEach(returnedData, function(value, key){
                while (i < 10) {
                  if(value[i].username == username) {
                    if(value[i].password == password) {
                     alert("Logged In");
                    }
                  }
                  i = i + 1;
                }
              });
            }, 
            function() {

              // this is error handler
            } 
          );
          return deferred.promise;  
      }

  }

  angular.module('assignment1App')
    .service ('serviceCallJson', serviceCallJson)

  angular.module('assignment1App')
  .service ('validateIn', ['serviceCallJson', validateIn])

tabs = {}

def new_tab():
    global browser
    hpos = browser.window_handles.index(browser.current_window_handle)
    browser.execute_script("window.open('');")
    browser.switch_to.window(browser.window_handles[hpos + 1])
    return(browser.current_window_handle)
    
def switch_tab(name):
    global tabs
    global browser
    if not name in tabs.keys():
        tabs[name] = {'window_handle': new_tab(), 'url': url+name}
        browser.get(tabs[name]['url'])
    else:
        browser.switch_to.window(tabs[name]['window_handle'])

Up through C++03, your first example was valid, but used a deprecated implicit conversion--a string literal should be treated as being of type char const *, since you can't modify its contents (without causing undefined behavior).

As of C++11, the implicit conversion that had been deprecated was officially removed, so code that depends on it (like your first example) should no longer compile.

You've noted one way to allow the code to compile: although the implicit conversion has been removed, an explicit conversion still works, so you can add a cast. I would not, however, consider this "fixing" the code.

Truly fixing the code requires changing the type of the pointer to the correct type:

char const *p = "abc"; // valid and safe in either C or C++.

As to why it was allowed in C++ (and still is in C): simply because there's a lot of existing code that depends on that implicit conversion, and breaking that code (at least without some official warning) apparently seemed to the standard committees like a bad idea.

Use combine from moreutils package, a sets utility that supports not, and, or, xor operations

combine file1 not file2

i.e give me lines that are in file1 but not in file2

OR give me lines in file1 minus lines in file2

Note: combine sorts and finds unique lines in both files before performing any operation but diff does not. So you might find differences between output of diff and combine.

So in effect you are saying

Find distinct lines in file1 and file2 and then give me lines in file1 minus lines in file2

In my experience, it's much faster than other options

Use jquery cookie plugin, the link as working today: https://github.com/js-cookie/js-cookie

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.

More details about the function utl_raw.cast_to_raw

Also, for other readers, if you are trying to do this in Django AND your server allows local_infile (you can check by typing SHOW VARIABLES via a mysql client) then you can add this to your settings.py file (since python MySQLdb doesn't by default read the .my.cnf file):

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mydb',
        'USER': 'myname',
        'PASSWORD': 'mypass',
        'HOST': 'myserver',
        'PORT': '3306',
        'OPTIONS' : {
            'local_infile':1,
        },
    }
}

save() can take a file-like object as well as a path, so you can use an in-memory buffer like a StringIO:

buf = StringIO.StringIO()
im.save(buf, format='JPEG')
jpeg = buf.getvalue()

There are several ways to accomplish that in Vim. I don't know which are most similar to Sublime Text's though.

The first one would be via multiline insert mode. Put your cursor to the second "a" in the first line, press Ctrl-V, select all lines, then press I, and put in a doublequote. Pressing <esc> will repeat the operation on every line.

The second one is via macros. Put the cursor on the first character, and start recording a macro with qa. Go the your right with llll, enter insert mode with a, put down a doublequote, exit insert mode, and go back to the beginning of your row with <home> (or equivalent). Press j to move down one row. Stop recording with q. And then replay the macro with @a. Several times.

Does any of the above approaches work for you?

Another easy way to filter out null values from multiple columns in spark dataframe. Please pay attention there is AND between columns.

df.filter(" COALESCE(col1, col2, col3, col4, col5, col6) IS NOT NULL")

If you need to filter out rows that contain any null (OR connected) please use

df.na.drop()

Pure CSS method

It is possible to center a video inside an element just like a cover sized background-image without JS using the object-fit attribute or CSS Transforms.

2021 answer: object-fit

As pointed in the comments, it is possible to achieve the same result without CSS transform, but using object-fit, which I think it's an even better option for the same result:

.video-container {
    height: 300px;
    width: 300px;
    position: relative;
}

.video-container video {
  width: 100%;
  height: 100%;
  position: absolute;
  object-fit: cover;
  z-index: 0;
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
    <video autoplay muted loop>
        <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
    </video>
    <div class="caption">
      <h2>Your caption here</h2>
    </div>
</div>

Previous answer: CSS Transform

You can set a video as a background to any HTML element easily thanks to transform CSS property.

Note that you can use the transform technique to center vertically and horizontally any HTML element.

.video-container {
  height: 300px;
  width: 300px;
  overflow: hidden;
  position: relative;
}

.video-container video {
  min-width: 100%;
  min-height: 100%;
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translateX(-50%) translateY(-50%);
}

/* Just styling the content of the div, the *magic* in the previous rules */
.video-container .caption {
  z-index: 1;
  position: relative;
  text-align: center;
  color: #dc0000;
  padding: 10px;
}

<div class="video-container">
  <video autoplay muted loop>
    <source src="https://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" type="video/mp4" />
  </video>
  <div class="caption">
    <h2>Your caption here</h2>
  </div>
</div>

No need for Javascript, you just have to add a target="_blank" attribute in your form tag.

<form target="_blank" action="http://example.com"
      method="post" id="mc-embedded-subscribe-form"
      name="mc-embedded-subscribe-form" class="validate"
>

Use a function like this:

    public static string FlattenException(Exception exception)
    {
        var stringBuilder = new StringBuilder();

        while (exception != null)
        {
            stringBuilder.AppendLine(exception.Message);
            stringBuilder.AppendLine(exception.StackTrace);

            exception = exception.InnerException;
        }

        return stringBuilder.ToString();
    }

Then you can call it like this:

try
{
    // invoke code above
}
catch(MyCustomException we)
{
    Debug.Writeline(FlattenException(we));
}

No there isn't. Instead use a while loop such as:

while 1:
 ...statements...
  if cond:
    break

Here's a simple function that I use.

var pad=function(num,field){
    var n = '' + num;
    var w = n.length;
    var l = field.length;
    var pad = w < l ? l-w : 0;
    return field.substr(0,pad) + n;
};

For example:

pad    (20,'     ');    //   20
pad   (321,'     ');    //  321
pad (12345,'     ');    //12345
pad (   15,'00000');    //00015
pad (  999,'*****');    //**999
pad ('cat','_____');    //__cat  

8-bit characters with leading 0

'sometext'
        .split('')
        .map((char) => '00'.concat(char.charCodeAt(0).toString(2)).slice(-8))
        .join(' ');

If you need 6 or 7 bit, just change .slice(-8)

if (User.Identity.IsAuthenticated)
{
    Page.Title = "Home page for " + User.Identity.Name;
}
else
{
    Page.Title = "Home page for guest user.";
}

I'd say export your server config in IIS manager:

1. In IIS manager, click the Server node
2. Go to Shared Configuration under "Management"
3. Click “Export Configuration”. (You can use a password if you are sending them across the internet, if you are just gonna move them via a USB key then don't sweat it.)

4. Move these files to your new server

   administration.config
   applicationHost.config
   configEncKey.key 
   

5. On the new server, go back to the “Shared Configuration” section and check “Enable shared configuration.” Enter the location in physical path to these files and apply them.

6. It should prompt for the encryption password(if you set it) and reset IIS.

BAM! Go have a beer!

Use PtrSafe and see how that works on Excel 2010.

Corrected typo from the book "Microsoft Excel 2010 Power Programming with VBA".

#If vba7 and win64 then
  declare ptrsafe function ....
#Else
  declare function ....
#End If

val(application.version)>12.0 won't work because Office 2010 has both 32 and 64 bit versions

That's a bit of informal terminology.

As far as Git is concerned, every other repository is just a remote.

Generally speaking, upstream is where you cloned from (the origin). Downstream is any project that integrates your work with other works.

The terms are not restricted to Git repositories.

For instance, Ubuntu is a Debian derivative, so Debian is upstream for Ubuntu.

This works fine too:

HttpContext.Current.Server.MapPath(relativePath)

Where relative path is something like "~/foo/file.jpg"

About access

<ol class="viewer-nav">
    <li *ngFor="let section of sections" 
        [attr.data-sectionvalue]="section.value"
        (click)="get_data($event)">
        {{ section.text }}
    </li>  
</ol>

And

get_data(event) {
   console.log(event.target.dataset.sectionvalue)
}

After some experimentation (see below), I can confirm that as of September 2017, nothing has changed with regards to the functionality described in the accepted answer:-

1. Rextester demo for Oracle 11g: Empty strings are inserted as NULLs for both VARCHAR and VARCHAR2.
2. LiveSQL demo for Oracle 12c: Same results.

The historical reason for these two keywords is explained well in an answer to a different question.

There are different ways to do so. You can use DateTime.Now.ToLongTimeString() which returns only the time in string format.

Declare @number float = 35.44987665;
Select round(@number,2) 

This is simple and sort. Use hsla css function like below

.transparent {
   background-color: hsla(0,0%,4%,.4);
}

call listView.scheduleLayoutAnimation(); before changing the list

This also works for me:-

@Temporal(TemporalType.TIMESTAMP)   
@Column(name = "CREATE_DATE_TIME", nullable = false, updatable = false, insertable = false, columnDefinition = "TIMESTAMP DEFAULT CURRENT_TIMESTAMP")
public Date getCreateDateTime() {
    return createDateTime;
}

public void setCreateDateTime(Date createDateTime) {
    this.createDateTime = createDateTime;
}

You can look up an object's keys and values by either invoking JavaScript's native for in loop:

var obj = {
    foo:    'bar',
    base:   'ball'
};

for(var key in obj) {
    alert('key: ' + key + '\n' + 'value: ' + obj[key]);
}

or using jQuery's .each() method:

$.each(obj, function(key, element) {
    alert('key: ' + key + '\n' + 'value: ' + element);
});

With the exception of six primitive types, everything in ECMA-/JavaScript is an object. Arrays; functions; everything is an object. Even most of those primitives are actually also objects with a limited selection of methods. They are cast into objects under the hood, when required. To know the base class name, you may invoke the Object.prototype.toString method on an object, like this:

alert(Object.prototype.toString.call([]));

The above will output [object Array].

There are several other class names, like [object Object], [object Function], [object Date], [object String], [object Number], [object Array], and [object Regex].

Please try this:

DELETE FROM `table` WHERE id >=163 and id<= 265

It is returning a Buffer object.

If you want it in a string, you can convert it with data.toString():

var fs = require("fs");

fs.readFile("test.txt", function (err, data) {
    if (err) throw err;
    console.log(data.toString());
});

you can use enum constructor for enum to have primitive data type..

public enum DaysOfWeek {
    MONDAY(1),
    TUESDAY(2),
    WEDNESDAY(3),
    THURSDAY(4),
    FRIDAY(5),
    SATURDAY(6),
    SUNDAY(7);

    private int value;
    private DaysOfWeek(int value) {
        this.value = value;
    }

    public int getValue() {
        return this.value;
    }

    private static final SparseArray<DaysOfWeek> map = new SparseArray<DaysOfWeek>();

    static
    {
         for (DaysOfWeek daysOfWeek : DaysOfWeek.values())
              map.put(daysOfWeek.value, daysOfWeek);
    }

    public static DaysOfWeek from(int value) {
        return map.get(value);
    }
}

you can use to pass int as extras then pull it from enum using its value.

dex2jar helps to decompile your apk but not 100%. You will have some problems with .smali files. Dex2jar cannot convert it to java. I know one application that can decompile your apk source files and no problems with .smali files. Here is a link http://www.hensence.com/en/smali2java/

Double quotes should work too... it should create a string, then it should APPEND/INSERT the casted STRING value of $myVar in between 2 empty strings.

If you just want a delay

from time import *

sleep(20)

On my Arch Linux install, gems were installed to the ~/.gem/ruby/2.6.0/bin directory if installed as user, or /root/.gem/ruby/2.6.0/bin if installed via sudo. Just append the appropriate one to your $PATH environment variable:

export PATH=$PATH:/home/your_username/.gem/ruby/2.6.0/bin

The error is completely correct.

As it's trying to tell you, .sort() takes a function that returns number, not boolean.

You need to return negative if the first item is smaller; positive if it it's larger, or zero if they're equal.

Change

$info=$_POST['id[]'];

to

$info=$_POST['id'];

by adding [] to the end of your form field names, PHP will automatically convert these variables into arrays.

In Flutter Container() widget use for styling your widget.Using Container() widget you can set border or rounded corner of any widget

If you want to set any type of styling & set decoration put that widget into the Container() widget, that provide many property to decoration.

Container(
  width: 100,
  padding: EdgeInsets.all(10),
  alignment: Alignment.center,
  decoration: BoxDecoration(
          color: Colors.blueAccent,
          borderRadius: BorderRadius.circular(30)), // make rounded corner
  child: Text("Click"),
)

clearing the cache works for me.
