Using visual studio, do the following

Create a project of type SQL Server-->SQL Server Database Project

open the sql server explorer CTL-\ , CTL-S

add a SQL Server by right clicking on the SQL SERVER icon. Selcet ADD NEW SERVER

navigate down to the table you are interested in

right click--> VIEW DATA

Click the top left cell to highlight everything (ctl-A doesnt seem to work)

Right Click -->SCript

This is fabulous. I have tried everything listed above over the years. I know there is a tool out there that will do this and much more, cant think of the name of it. But it is very expensive.

Good luck. I just figured this out. Have not tested it extensively w/ text fields etc, but it looks like it gets you a long ways down the road.

Greg

simple as this myObj.name = value;

Try this on your context:

public class MyDatabase : DbContext
{
    public MyDatabase ()
        : base(ContextHelper.CreateConnection("Connection string"), true)
    {
        ((IObjectContextAdapter)this).ObjectContext.CommandTimeout = 180; // seconds
    }
}

If you want to define the timeout in the connection string, use the Connection Timeout parameter like in the following connection string:

<connectionStrings>

<add name="AdventureWorksEntities"
connectionString="metadata=.\AdventureWorks.csdl|.\AdventureWorks.ssdl|.\AdventureWorks.msl;
provider=System.Data.SqlClient;provider connection string='Data Source=localhost;
Initial Catalog=AdventureWorks;Integrated Security=True;Connection Timeout=60;
multipleactiveresultsets=true'" providerName="System.Data.EntityClient" />

</connectionStrings>

Source: How to: Define the Connection String

C# uses the UTF16 format for its strings.
So, besides just converting the types, you should also be conscious about the string's actual format.

When compiling for Multi-byte Character set Visual Studio and the Win API assumes UTF8 (Actually windows encoding which is Windows-28591 ).
When compiling for Unicode Character set Visual studio and the Win API assume UTF16.

So, you must convert the string from UTF16 to UTF8 format as well, and not just convert to std::string.
This will become necessary when working with multi-character formats like some non-latin languages.

The idea is to decide that std::wstring always represents UTF16.
And std::string always represents UTF8.

This isn't enforced by the compiler, it's more of a good policy to have.

#include "stdafx.h"
#include <string>
#include <codecvt>
#include <msclr\marshal_cppstd.h>

using namespace System;

int main(array<System::String ^> ^args)
{
    System::String^ managedString = "test";

    msclr::interop::marshal_context context;

    //Actual format is UTF16, so represent as wstring
    std::wstring utf16NativeString = context.marshal_as<std::wstring>(managedString); 

    //C++11 format converter
    std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> convert;

    //convert to UTF8 and std::string
    std::string utf8NativeString = convert.to_bytes(utf16NativeString);

    return 0;
}

Or have it in a more compact syntax:

int main(array<System::String ^> ^args)
{
    System::String^ managedString = "test";

    msclr::interop::marshal_context context;
    std::wstring_convert<std::codecvt_utf8_utf16<wchar_t>> convert;

    std::string utf8NativeString = convert.to_bytes(context.marshal_as<std::wstring>(managedString));

    return 0;
}

You can cast like this:

return this.createMarkerStyle(<MarkerSymbolInfo> symbolInfo);

Or like this if you want to be compatible with tsx mode:

return this.createMarkerStyle(symbolInfo as MarkerSymbolInfo);

Just remember that this is a compile-time cast, and not a runtime cast.

SELECT TOP 10*from TABLE1 ORDER BY ID DESC

Where ID is the primary key of the TABLE1.

I know the user asked this for Linux, but I had this issue in Windows (10 64bits) and found little information, so this is how I solved it:

• Download LIBAV, I used libav-11.3-win64.7z. Just copy "avprobe.exe" and all DLLs from "/win64/usr/bin" to where "youtube-dl.exe" is.

In case LIBAV does not help, try with FFMPEG, copying the contents of the "bin" folder to where "youtube-dl.exe" is. That did not help me, but others said it did, so it may worth a try.

Hope this helps someone having the issue in Windows.

Corrected a few things and added an alternative select - delete as appropriate.

In the right bottom edge there are information about NetBeans updates. Left to it, there's the tasks running (building, running application etc). Click on it, right click the process you want and select Show Output.

Make sure the following line code should be there in AssemblyInfo.cs file.

[assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config", Watch = true)]

and also check for this line in Application_start() method.

log4net.Config.XmlConfigurator.Configure();

Alternative solution to the updated question using Java 8:

Bar[] result = foos.stream()
    .map(x -> new Bar(x))
    .toArray(size -> new Bar[size]);

The two common approaches are either that the class should have a constructor for the DAL to use, or the DAL should use reflection to hydrate objects.

Here are 535 ways to reload a page using javascript, very cool:

Here are the first 20:

location = location
location = location.href
location = window.location
location = self.location
location = window.location.href
location = self.location.href
location = location['href']
location = window['location']
location = window['location'].href
location = window['location']['href']
location = window.location['href']
location = self['location']
location = self['location'].href
location = self['location']['href']
location = self.location['href']
location.assign(location)
location.replace(location)
window.location.assign(location)
window.location.replace(location)
self.location.assign(location)

and the last 10:

self['location']['replace'](self.location['href'])
location.reload()
location['reload']()
window.location.reload()
window['location'].reload()
window.location['reload']()
window['location']['reload']()
self.location.reload()
self['location'].reload()
self.location['reload']()
self['location']['reload']()

On the unstaged file, click on the three dots on the right side. Once you click it, a popover menu will appear where you can then Discard file.

Here is the shortest method possible:

if (Math.abs(v-550)<50) console.log('short')
if ((v-500)*(v-600)<0) console.log('short')

Parametrized:

if (Math.abs(v-max+v-min)<max+min) console.log('short')
if ((v-min)*(v-max)<0) console.log('short')

You can divide both sides by 2 if you don't understand how the first one works;)

The cursor.copyfrom solution as provided by @jopseph.sheedy (https://stackoverflow.com/users/958118/joseph-sheedy) above (https://stackoverflow.com/a/30721460/11100064) is indeed lightning fast.

However, the example he gives are not generically usable for a record with any number of fields and it took me while to figure out how to use it correctly.

The IteratorFile needs to be instantiated with tab-separated fields like this (r is a list of dicts where each dict is a record):

    f = IteratorFile("{0}\t{1}\t{2}\t{3}\t{4}".format(r["id"],
        r["type"],
        r["item"],
        r["month"],
        r["revenue"]) for r in records)

To generalise for an arbitrary number of fields we will first create a line string with the correct amount of tabs and field placeholders : "{}\t{}\t{}....\t{}" and then use .format() to fill in the field values : *list(r.values())) for r in records:

        line = "\t".join(["{}"] * len(records[0]))

        f = IteratorFile(line.format(*list(r.values())) for r in records)

complete function in gist here.

To find a particular Element is present or not, we have to use findElements() method instead of findElement()..

int i=driver.findElements(By.xpath(".......")).size();
if(i=0)
System.out.println("Element is not present");
else
System.out.println("Element is present");

this is worked for me.. suggest me if i am wrong..

There are many ways to achieve this, but the most important consideration to measure elapsed time is to use System.nanoTime() and TimeUnit.NANOSECONDS as the time unit. Why should I do this? Well, it is because System.nanoTime() method returns a high-resolution time source, in nanoseconds since some reference point (i.e. Java Virtual Machine's start up).

This method can only be used to measure elapsed time and is not related to any other notion of system or wall-clock time.

For the same reason, it is recommended to avoid the use of the System.currentTimeMillis() method for measuring elapsed time. This method returns the wall-clock time, which may change based on many factors. This will be negative for your measurements.

Note that while the unit of time of the return value is a millisecond, the granularity of the value depends on the underlying operating system and may be larger. For example, many operating systems measure time in units of tens of milliseconds.

So here you have one solution based on the System.nanoTime() method, another one using Guava, and the final one Apache Commons Lang

public class TimeBenchUtil
{
    public static void main(String[] args) throws InterruptedException
    {
        stopWatch();
        stopWatchGuava();
        stopWatchApacheCommons();
    }

    public static void stopWatch() throws InterruptedException
    {
        long endTime, timeElapsed, startTime = System.nanoTime();

        /* ... the code being measured starts ... */

        // sleep for 5 seconds
        TimeUnit.SECONDS.sleep(5);

        /* ... the code being measured ends ... */

        endTime = System.nanoTime();

        // get difference of two nanoTime values
        timeElapsed = endTime - startTime;

        System.out.println("Execution time in nanoseconds   : " + timeElapsed);
    }

    public static void stopWatchGuava() throws InterruptedException
    {
        // Creates and starts a new stopwatch
        Stopwatch stopwatch = Stopwatch.createStarted();

        /* ... the code being measured starts ... */

        // sleep for 5 seconds
        TimeUnit.SECONDS.sleep(5);
        /* ... the code being measured ends ... */

        stopwatch.stop(); // optional

        // get elapsed time, expressed in milliseconds
        long timeElapsed = stopwatch.elapsed(TimeUnit.NANOSECONDS);

        System.out.println("Execution time in nanoseconds   : " + timeElapsed);
    }

    public static void stopWatchApacheCommons() throws InterruptedException
    {
        StopWatch stopwatch = new StopWatch();
        stopwatch.start();

        /* ... the code being measured starts ... */

        // sleep for 5 seconds
        TimeUnit.SECONDS.sleep(5);

        /* ... the code being measured ends ... */

        stopwatch.stop();    // Optional

        long timeElapsed = stopwatch.getNanoTime();

        System.out.println("Execution time in nanoseconds   : " + timeElapsed);
    }
}

Weird issue, but this helped me to solve my issue. Sometimes even the easiest things are hard to figure out...

Instead of using /js/main.css in my script-tag I used js/main.css

YES, it did actually make a difference. I'm sitting on WAMP / Windows and I didn't have a vhost but just used localhost/<project>

If I reference to /js/main.css then I reference to localhost/css/main.css and not to localhost/<project>/css/main.css

When you think of it, it's quite obvious but if someone stumbles upon this I thought I would share this answer.

This simple way...

var string = "{firstName:'name1', lastName:'last1'}";
eval('var obj='+string);
alert(obj.firstName);

output

name1

You can use the stored procedure sp_columns which would return information pertaining to all columns for a given table. More info can be found here http://msdn.microsoft.com/en-us/library/ms176077.aspx

You can also do it by a SQL query. Some thing like this should help:

SELECT * FROM sys.columns WHERE object_id = OBJECT_ID('dbo.yourTableName') 

Or a variation would be:

SELECT   o.Name, c.Name
FROM     sys.columns c 
         JOIN sys.objects o ON o.object_id = c.object_id 
WHERE    o.type = 'U' 
ORDER BY o.Name, c.Name

This gets all columns from all tables, ordered by table name and then on column name.

You can do it by making form and displaying it using ShowDialogBox....

Form.ShowDialog Method - Shows the form as a modal dialog box.

Example:

public void ShowMyDialogBox()
{
   Form2 testDialog = new Form2();

   // Show testDialog as a modal dialog and determine if DialogResult = OK.
   if (testDialog.ShowDialog(this) == DialogResult.OK)
   {
      // Read the contents of testDialog's TextBox.
      this.txtResult.Text = testDialog.TextBox1.Text;
   }
   else
   {
      this.txtResult.Text = "Cancelled";
   }
   testDialog.Dispose();
}

I had this problem changing the icon from drawable to mipmap.

I only missed the line

In Java7 you can use:

import static java.nio.charset.StandardCharsets.*;

byte[] ptext = myString.getBytes(ISO_8859_1); 
String value = new String(ptext, UTF_8); 

This has the advantage over getBytes(String) that it does not declare throws UnsupportedEncodingException.

If you're using an older Java version you can declare the charset constants yourself:

import java.nio.charset.Charset;

public class StandardCharsets {
    public static final Charset ISO_8859_1 = Charset.forName("ISO-8859-1");
    public static final Charset UTF_8 = Charset.forName("UTF-8");
    //....
}

Happy Coding !!

just simply use list.pop() now if you want it the other way use : list.popleft()

Since the file is modified by both, Either you need to add it by

git add Whereami.xcodeproj/project.xcworkspace/xcuserdatauser.xcuserdatad/UserInterfaceState.xcuserstate

Or if you would like to ignore yoyr changes, then do

git reset HEAD Whereami.xcodeproj/project.xcworkspace/xcuserdatauser.xcuserdatad/UserInterfaceState.xcuserstate

After that just switch your branch.This should do the trick.

By using AppCompat textAllCaps in Android Apps supporting older API's (less than 14)

There is one UI widgets that ships with AppCompat named CompatTextView is a Custom TextView extension that adds support for textAllCaps

For newer android API > 14 you can use :

android:textAllCaps="true"

A simple example:

<android.support.v7.internal.widget.CompatTextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:textAllCaps="true"/>

Source:developer.android

Update:

As it so happens CompatTextView was replaced by AppCompatTextView in latest appcompat-v7 library ~ Eugen Pechanec

@MykolaGolubyev has already given wonderful explanation. I was looking for a solution to do somthing like this MyClass obj ( MyAnotherClass() ) but the compiler was interpreting it as a function declaration.

C++11 has braced-init-list. Using this we can do something like this

Temp t{String()};

However, this:

Temp t(String());

throws compilation error as it considers t as of type Temp(String (*)()).

#include <iostream>

class String {
public:
    String(const char* str): ptr(str)
    {
        std::cout << "Constructor: " << str << std::endl;
    }
    String(void): ptr(nullptr)
    {
        std::cout << "Constructor" << std::endl;
    }
    virtual ~String(void)
    {
        std::cout << "Destructor" << std::endl;
    }

private:
    const char *ptr;
};

class Temp {
public:
    Temp(String in): str(in)
    {
        std::cout << "Temp Constructor" << std::endl;
    }

    Temp(): str(String("hello"))
    {
        std::cout << "Temp Constructor: 2" << std::endl;
    }
    virtual ~Temp(void)
    {
        std::cout << "Temp Destructor" << std::endl;
    }

    virtual String get_str()
    {
        return str;
    }

private:
    String str;
};

int main(void)
{
    Temp t{String()}; // Compiles Success!
    // Temp t(String()); // Doesn't compile. Considers "t" as of type: Temp(String (*)())
    t.get_str(); // dummy statement just to check if we are able to access the member
    return 0;
}

In addition you can use via data attribute

<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>

In this particular case you don't need to write javascript.

You can see more here: http://getbootstrap.com/2.3.2/javascript.html#modals

Just use below method with two Date objects. If you want to pass current date, just pass new Date() as a second parameter as it is initialised with current time.

public String getDateDiffString(Date dateOne, Date dateTwo)
{
    long timeOne = dateOne.getTime();
    long timeTwo = dateTwo.getTime();
    long oneDay = 1000 * 60 * 60 * 24;
    long delta = (timeTwo - timeOne) / oneDay;

    if (delta > 0) {
        return "dateTwo is " + delta + " days after dateOne";
    }
    else {
        delta *= -1;
        return "dateTwo is " + delta + " days before dateOne";
     }
}

Also, apart from from number of days, if, you want other parameter difference too, use below snippet,

int year = delta / 365;
int rest = delta % 365;
int month = rest / 30;
rest = rest % 30;
int weeks = rest / 7;
int days = rest % 7;

P.S Code is entirely taken from an SO answer.

Why you shouldn't and when you should use regular expressions?

First off, a common misnomer: Regexps are not for "parsing" HTML. Regexes can however "extract" data. Extracting is what they're made for. The major drawback of regex HTML extraction over proper SGML toolkits or baseline XML parsers are their syntactic effort and varying reliability.

Consider that making a somewhat dependable HTML extraction regex:

<a\s+class="?playbutton\d?[^>]+id="(\d+)".+?    <a\s+class="[\w\s]*title
[\w\s]*"[^>]+href="(http://[^">]+)"[^>]*>([^<>]+)</a>.+?

is way less readable than a simple phpQuery or QueryPath equivalent:

$div->find(".stationcool a")->attr("title");

There are however specific use cases where they can help.

• Many DOM traversal frontends don't reveal HTML comments <!--, which however are sometimes the more useful anchors for extraction. In particular pseudo-HTML variations <$var> or SGML residues are easy to tame with regexps.
• Oftentimes regular expressions can save post-processing. However HTML entities often require manual caretaking.
• And lastly, for extremely simple tasks like extracting <img src= urls, they are in fact a probable tool. The speed advantage over SGML/XML parsers mostly just comes to play for these very basic extraction procedures.

It's sometimes even advisable to pre-extract a snippet of HTML using regular expressions /<!--CONTENT-->(.+?)<!--END-->/ and process the remainder using the simpler HTML parser frontends.

Note: I actually have this app, where I employ XML parsing and regular expressions alternatively. Just last week the PyQuery parsing broke, and the regex still worked. Yes weird, and I can't explain it myself. But so it happened.
So please don't vote real-world considerations down, just because it doesn't match the regex=evil meme. But let's also not vote this up too much. It's just a sidenote for this topic.

Important update (Python 3.4):

Any identifier of the form __name (at least two leading underscores, at most one trailing underscore) is publicly replaced with _classname__name, where classname is the current class name with leading underscore(s) stripped.

Therefore, __name is private, while _classname__name is public.

https://docs.python.org/3/tutorial/classes.html#tut-private

Example

class Cat:
    def __init__(self, name='unnamed'):
        self.name = name
    def __print_my_name(self):
        print(self.name)
        
        
tom = Cat()
tom.__print_my_name() #Error
tom._Cat__print_my_name() #Prints name

Problems with your code and suggestions:

• Again you need to change the preferredSize of the component (here the Graph JPanel), not the size
• Don't set the JFrame's bounds.
• Call pack() on your JFrame after adding components to it and before calling setVisible(true)
• Your foreach loop won't work since the size of your ArrayList is 0 (test it to see that this is correct). Instead use a for loop going from 0 to 10.
• You should not have program logic inside of your paintComponent(...) method but only painting code. So I would make the ArrayList a class variable and fill it inside of the class's constructor.

Which will create a graph that looks like so:

I think you can use a simple WHERE clause to select only the count some record.

You can save effort with the new AsyncEnumerator NuGet Package, which didn't exist 4 years ago when the question was originally posted. It allows you to control the degree of parallelism:

using System.Collections.Async;
...

await ids.ParallelForEachAsync(async i =>
{
    ICustomerRepo repo = new CustomerRepo();
    var cust = await repo.GetCustomer(i);
    customers.Add(cust);
},
maxDegreeOfParallelism: 10);

Disclaimer: I'm the author of the AsyncEnumerator library, which is open source and licensed under MIT, and I'm posting this message just to help the community.

This should do the trick

export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get -q -y install mysql-server

Of course, it leaves you with a blank root password - so you'll want to run something like

mysqladmin -u root password mysecretpasswordgoeshere

Afterwards to add a password to the account.

You can see the results in MB format, with the division of 1024 x 1024 which is equal to 1 MB.

int dataSize = 1024 * 1024;

System.out.println("Used Memory   : " + (Runtime.getRuntime().totalMemory() - Runtime.getRuntime().freeMemory())/dataSize + " MB");
System.out.println("Free Memory   : " + Runtime.getRuntime().freeMemory()/dataSize + " MB");
System.out.println("Total Memory  : " + Runtime.getRuntime().totalMemory()/dataSize + " MB");
System.out.println("Max Memory    : " + Runtime.getRuntime().maxMemory()/dataSize + " MB");  

I have like 2 approaches using one with Rank and the other with ROW_NUMBER

This is my sample data

Age          Name                                               Gender     Salary
----------- -------------------------------------------------- ---------- -----------
1           Mark                                               Male       5000
2           John                                               Male       4500

7           Tom                                                Male       5500
8           Mary                                               Female     5000

11          Tom                                                Male       5500
12          Ron                                                Male       5000
13          Ramani                                             Female     7000

So here is my first query to find max salary and the person with that max salary for each Gender

    with CTE as(
    select RANK() over(partition by Gender Order by Salary desc) as [Rank],* from employees)
    select * from CTE where [Rank]=1


Rank                 Age          Name                                               Gender     Salary
-------------------- ----------- -------------------------------------------------- ---------- -----------
1                    10          Jodi                                               Female     7000
1                    13          Ramani                                             Female     7000
1                    9           Ben                                                Male       6500

So in this case, we can see there is a tie between these 2 female employees "Jodi" and "Ramani". In that case, As a tie-breaker I want to make use of Age as a deciding factor and person with more age is supposed to be displayed

with CTE as(
select RANK() over(partition by Gender Order by Salary desc,age desc) as [Rank],* from employees)
select * from CTE where [Rank]=1

Rank                 Age          Name                                               Gender     Salary
-------------------- ----------- -------------------------------------------------- ---------- -----------
1                    13          Ramani                                             Female     7000
1                    9           Ben                                                Male       6500

Usually, in this case for finding the highest salary, it doesn't make much difference even if Rank, Dense_Rank, or Row_Number() are used. But they have some impact in other cases.

I got it finally! Here is my way, and I hope it can help you :)

I don't know the reason why I need to install these, but it works on my computer. When you finish installing these packages, it's time to try. Oh yes, I need to tell you. This time when you want to compile your code, you should add -m32 after gcc, for example: gcc -m32 -o hello helloworld.c. Just make clean and make again. Good luck friends.

PS: my environment is: Ubuntu 14.04 64-bit (Trusty Tahr) and GCC version 4.8.4. I have written the solution in my blog, but it is in Chinese :-) - How to compass 32bit programm under ubuntu14.04.

Other answers have already explained why virtual function calls don't work as expected when called from a constructor. I'd like to instead propose another possible work around for getting polymorphic-like behavior from a base type's constructor.

By adding a template constructor to the base type such that the template argument is always deduced to be the derived type it's possible to be aware of the derived type's concrete type. From there, you can call static member functions for that derived type.

This solution does not allow non-static member functions to be called. While execution is in the base type's constructor, the derived type's constructor hasn't even had time to go through it's member initialization list. The derived type portion of the instance being created hasn't begun being initialized it. And since non-static member functions almost certainly interact with data members it would be unusual to want to call the derived type's non-static member functions from the base type's constructor.

Here is a sample implementation :

#include <iostream>
#include <string>

struct Base {
protected:
    template<class T>
    explicit Base(const T*) : class_name(T::Name())
    {
        std::cout << class_name << " created\n";
    }

public:
    Base() : class_name(Name())
    {
        std::cout << class_name << " created\n";
    }


    virtual ~Base() {
        std::cout << class_name << " destroyed\n";
    }

    static std::string Name() {
        return "Base";
    }

private:
    std::string class_name;
};


struct Derived : public Base
{   
    Derived() : Base(this) {} // `this` is used to allow Base::Base<T> to deduce T

    static std::string Name() {
        return "Derived";
    }
};

int main(int argc, const char *argv[]) {

    Derived{};  // Create and destroy a Derived
    Base{};     // Create and destroy a Base

    return 0;
}

This example should print

Derived created
Derived destroyed
Base created
Base destroyed

When a Derived is constructed, the Base constructor's behavior depends on the actual dynamic type of the object being constructed.

You can set in the config.inc.php file of your phpMyAdmin installation.

$cfg['Servers'][$i]['host'] = '';

In C++, you can use the global function std::getline, it takes a string and a stream and an optional delimiter and reads 1 line until the delimiter specified is reached. An example:

#include <string>
#include <iostream>
#include <fstream>

int main() {
    std::ifstream input("filename.txt");
    std::string line;

    while( std::getline( input, line ) ) {
        std::cout<<line<<'\n';
    }

    return 0;
}

This program reads each line from a file and echos it to the console.

For C you're probably looking at using fgets, it has been a while since I used C, meaning I'm a bit rusty, but I believe you can use this to emulate the functionality of the above C++ program like so:

#include <stdio.h>

int main() {
    char line[1024];
    FILE *fp = fopen("filename.txt","r");

    //Checks if file is empty
    if( fp == NULL ) {                       
        return 1;
    }

    while( fgets(line,1024,fp) ) {
        printf("%s\n",line);
    }

    return 0;
}

With the limitation that the line can not be longer than the maximum length of the buffer that you're reading in to.

1. It is possible to get the command line shell output of a process as described here : http://www.c-sharpcorner.com/UploadFile/edwinlima/SystemDiagnosticProcess12052005035444AM/SystemDiagnosticProcess.aspx

2. This depends on mencoder. If it ouputs this status on the command line then yes :)

I come across a situation where i need to insert the data in the database & simultaneously require the primary id using entity framework. Solution :

long id;
IGenericQueryRepository<myentityclass, Entityname> InfoBase = null;
try
 {
    InfoBase = new GenericQueryRepository<myentityclass, Entityname>();
    InfoBase.Add(generalinfo);
    InfoBase.Context.SaveChanges();
    id = entityclassobj.ID;
    return id;
 }

Made a simple implementation of what I believe to be what you want to achieve. You can use the class later with the following arguments:

• int (milliseconds to wait until to run the code)
• bool (if true it returns instantly and runs the code after specified time on another thread)
• variable arguments (exactly what you'd feed to std::bind)

You can change std::chrono::milliseconds to std::chrono::nanoseconds or microseconds for even higher precision and add a second int and a for loop to specify for how many times to run the code.

Here you go, enjoy:

#include <functional>
#include <chrono>
#include <future>
#include <cstdio>

class later
{
public:
    template <class callable, class... arguments>
    later(int after, bool async, callable&& f, arguments&&... args)
    {
        std::function<typename std::result_of<callable(arguments...)>::type()> task(std::bind(std::forward<callable>(f), std::forward<arguments>(args)...));

        if (async)
        {
            std::thread([after, task]() {
                std::this_thread::sleep_for(std::chrono::milliseconds(after));
                task();
            }).detach();
        }
        else
        {
            std::this_thread::sleep_for(std::chrono::milliseconds(after));
            task();
        }
    }

};

void test1(void)
{
    return;
}

void test2(int a)
{
    printf("%i\n", a);
    return;
}

int main()
{
    later later_test1(1000, false, &test1);
    later later_test2(1000, false, &test2, 101);

    return 0;
}

Outputs after two seconds:

101

Without the typedef word, in C++ the declaration would declare a variable FunctionFunc of type pointer to function of no arguments, returning void.

With the typedef it instead defines FunctionFunc as a name for that type.

You are getting AttributeError because you're calling groups on None, which hasn't any methods.

regex.search returning None means the regex couldn't find anything matching the pattern from supplied string.

when using regex, it is nice to check whether a match has been made:

Result = re.search(SearchStr, htmlString)

if Result:
    print Result.groups()

Program to get those three elements. I have just sorted the array/list first and them updated minCloseness based upon each triplet.

public int[] threeSumClosest(ArrayList<Integer> A, int B) {
    Collections.sort(A);
    int ansSum = 0;
    int ans[] = new int[3];
    int minCloseness = Integer.MAX_VALUE;
    for (int i = 0; i < A.size()-2; i++){
        int j = i+1;
        int k = A.size()-1;
        while (j < k){
            int sum = A.get(i) + A.get(j) + A.get(k);
            if (sum < B){
                j++;
            }else{
                k--;
            }
            if (minCloseness >  Math.abs(sum - B)){
                minCloseness = Math.abs(sum - B);
                ans[0] = A.get(i); ans[1] = A.get(j); ans[2] = A.get(k);
            }
        }
    }
    return ans;
}

Keep a look out for SQL Server to support the 'INSERT ALL' Statement. Oracle has it already, it looks like this (SQL Cookbook):

insert all
  when loc in ('NEW YORK', 'BOSTON') THEN
   into dept_east(deptno, dname, loc) values(deptno, dname, loc)
  when loc in ('CHICAGO') THEN
   into dept_mid(deptno, dname, loc) values(deptno, dname, loc)
  else
   into dept_west(deptno, dname, loc) values(deptno, dname, loc)
select deptno, dname, loc
  from dept

I had the same problem and although I was already using an SSL server, simply changing the links to https wasn't working as there was an underlying problem.

Click here for image

That highlighted bit told me that we should be given the option to trust the certificate, but since this is the app store, working through Safari that recovery suggestion just isn't presented.

I wasn't happy with the existing solutions because:

• Some options require dependance on a third party (Dropbox)
• We weren't willing to pay for an SSL certificate
  • Free SSL certificates are only a temporary solution.

I finally found a solution by creating a Self Signed Root Certificate Authority and generating our server's SSL certificate using this.

I used Keychain Access and OSX Server, but there are other valid solutions to each step

Creating a Certificate Authority

From what I gather, certificate authorities are used to verify that certificates are genuine. Since we're about to create one ourselves, it's not exactly secure, but it means that you can trust all certificates from a given authority. A list of these authorities is usually included by default in your browsers as these are actually trusted. (GeoTrust Global CA, Verisign etc)

• Open Keychain and use the certificate assistant to create an authority

• Fill in your Certificate Authority Information

• I don't know if it's necessary, but I made the authority trusted.

Generating a Certificate Signing Request

In our case, certificate signing requests are generated by the server admin. Simply it's a file that asks "Can I have a certificate with this information for my site please".

• Next you'll have to create your Certificate Signing Request (I used OSX Server's Certificates manager for this bit

• Fill in your certificate information (Must contain only ascii chars!, thanks @Jasper Blues)

• Save the generate CSR somewhere

Creating the Certificate

Acting as the certificate authority again, it's up to you to decide if the person who sent you the CSR is genuine and they're not pretending to be somebody else. Real authorities have their own ways of doing this, but since you are hopefully quite sure that you are you, your verification should be quite certain :)

• Go back to Keychain Access and open the "Create A Certificate.." option as shown

• Drag in your saved CSR to the box indicated

• Click the "Let me override defaults for this request button"

• I like to increase the validity period.

• For some reason, we have to fill in some information again

• Click continue on this screen

• MAKE SURE YOU CLICK SSL SERVER AUTHENTICATION, this one caused me some headaches.

• You can click continue through the rest of the options.

• The Mail app will open giving you the chance to send the certificate. Instead of emailing, right click it and save it.

Installing the Certificate

We now need to set up the server to use the certificate we just created for it's SSL traffic.

• If the device your working on is your server, you might find the certificate is already installed.

• If not though, double click the Pending certificate and drag the PEM file that we just saved from the email into the space indicated. (Alternatively, you can export your PEM from keychain if you didn't save it.)

• Update your server to use this new certificate. If you find that the new certificate won't "stick" and keeps reverting, go back to the bit in BOLD ITALIC CAPS

Setting Up Devices

Each device you need to install apps on will need to have a copy of this certificate authority so that they know they can trust SSL certificates from that authority

• Go back to Keychain Access and export your certificate authority as a .cer

• I then put this file on my server with my OTA apps, users can click this link and download the authority certificate. Emailing the certificate directly to users is also a valid option.

• Install the certificate on your device.

Test

• Make sure your plist links are https

  • Try and install an app! It should now work. The certificate authority is trusted and the SSL certificate came from that authority.

Your approach is correct. (Depending on the circumstances, you might want to use configurations.all { exclude ... }.) If these excludes really exclude more than a single dependency (I haven't ever noticed that when using them), please file a bug at http://forums.gradle.org, ideally with a reproducible example.

If you see this error in an umbrella header when building a dynamic framework, make sure you import your file as:

#import "MyFile.h"

and not as #import <MyFramework/MyFile.h>.

If you want to make using attributed strings easier, try using Attributed String Creator, which will generate the code for you. https://itunes.apple.com/us/app/attributed-string-creator/id730928349

In my case I had gulp-watch running that caused the problems. After stopping it I could execute Cleanup command.

if you want the color to change when you have simply add the :hover pseudo

div.e:hover {
    background-color:red;
}

If you look at the output you receive from print() and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b):

b'{\n  "note":"This file    .....

If you fetch the URL using a tool such as curl -v, you will see that the content type is

Content-Type: application/json; charset=utf-8

So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.

Change the last line of code to this:

info = json.loads(js.decode("utf-8"))

I made a swift extension based on @progrmr's answer.

It allows you to easily check if a UIViewController is on screen like so:

if someViewController.isOnScreen {
    // Do stuff here
}

The extension:

//
//  UIViewControllerExtension.swift
//

import UIKit

extension UIViewController{
    var isOnScreen: Bool{
        return self.isViewLoaded() && view.window != nil
    }
}

public void Method()
{
    if(something)
    {
        //some code
        if(!something2)
        {
            return;
        }
    }
    // The code i want to go if the second if is true
}

$parent doesn't work if there are multiple parents. instead of that we can define a parent index variable in init and use it

<div data-ng-init="parentIndex = $index" ng-repeat="f in foos">
  <div>
    <div data-ng-init="childIndex = $index" ng-repeat="b in foos.bars">
      <a ng-click="addSomething(parentIndex)">Add Something</a>
    </div>
  </div>
</div>

Without reading your code but just your scenario, I would solve by using localStorage. Here's an example, I'll use prompt() for short.

On page1:

window.onload = function() {
   var getInput = prompt("Hey type something here: ");
   localStorage.setItem("storageName",getInput);
}

On page2:

window.onload = alert(localStorage.getItem("storageName"));

You can also use cookies but localStorage allows much more spaces, and they aren't sent back to servers when you request pages.

Here is an ES6 version of Stoive's answer:

export class ImageDataConverter {
  constructor(dataURI) {
    this.dataURI = dataURI;
  }

  getByteString() {
    let byteString;
    if (this.dataURI.split(',')[0].indexOf('base64') >= 0) {
      byteString = atob(this.dataURI.split(',')[1]);
    } else {
      byteString = decodeURI(this.dataURI.split(',')[1]);
    }
    return byteString;
  }

  getMimeString() {
    return this.dataURI.split(',')[0].split(':')[1].split(';')[0];
  }

  convertToTypedArray() {
    let byteString = this.getByteString();
    let ia = new Uint8Array(byteString.length);
    for (let i = 0; i < byteString.length; i++) {
      ia[i] = byteString.charCodeAt(i);
    }
    return ia;
  }

  dataURItoBlob() {
    let mimeString = this.getMimeString();
    let intArray = this.convertToTypedArray();
    return new Blob([intArray], {type: mimeString});
  }
}

Usage:

const dataURL = canvas.toDataURL('image/jpeg', 0.5);
const blob = new ImageDataConverter(dataURL).dataURItoBlob();
let fd = new FormData(document.forms[0]);
fd.append("canvasImage", blob);

This will work if you're trying to change the fragment from another fragment.

Objects.requireNonNull(getActivity()).getSupportFragmentManager()
.beginTransaction()
.replace(R.id.home_fragment_container,new NewFragment())

NOTE As stated in the above answers, You need to have dynamic fragments.

A key currently still is not required ("required" in the meaning "it will not work without"), but I think there is a good reason for the warning.

But in the documentation you may read now : "All JavaScript API applications require authentication."

I'm sure that it's planned for the future , that Javascript API Applications will not work without a key(as it has been in V2).

You better use a key when you want to be sure that your application will still work in 1 or 2 years.

This happened to me when I have multiple angular modules in the same page

I encountered this error when I used partial views

One partial view had

<script src="~/Scripts/Items.js"></script>
<div ng-app="SearchModule">
    <div ng-controller="SearchSomething" class="col-md-1">
        <input class="searchClass" type="text" placeholder="Search" />
    </div>
</div>

Other had

<div ng-app="FeaturedItems" ng-controller="featured">
    <ul>
        <li ng-repeat="item in Items">{{item.Name}}</li>
    </ul>
</div>

I had them in same module with different controller and it started working

You should reference System.Web and call:

  HttpContext.Current.Server.MapPath(...)

You can use rails dbconsole to view the database that your rails application is using. It's alternative answer rails db. Both commands will direct you the command line interface and will allow you to use that database query syntax.

You are assigning reloaded items to global variable items in onResume(), but this will not reflect in ItemAdapter class, because it has its own instance variable called 'items'.

For refreshing ListView, add a refresh() in ItemAdapter class which accepts list data i.e items

class ItemAdapter
{
    .....

    public void refresh(List<Item> items)
    {
        this.items = items;
        notifyDataSetChanged();
    } 
}

update onResume() with following code

@Override
public void onResume()
{
    super.onResume();
    items.clear();
    items = dbHelper.getItems(); //reload the items from database
    **adapter.refresh(items);**
}

Use DateTime.AddDays() method with value of -1

var yesterday = DateTime.Today.AddDays(-1);

That will give you : {6/28/2012 12:00:00 AM}

You can also use

DateTime.Now.AddDays(-1)

That will give you previous date with the current time e.g. {6/28/2012 10:30:32 AM}

For this problem, I used a simple and rude method, rename the field name to password, the reason for this is that I use the mac navicat premium software in the visual operation error: Unknown column 'password' in 'field List ', the software itself uses password so that I can not easily operate. Therefore, I root into the database command line, run

Use mysql;

And then modify the field name:

ALTER TABLE user CHANGE authentication_string password text;

After all normal.

This is what the code would look like in a batch file(tested, works):

powershell -Command "& {set-location 'HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings'; set-location ZoneMap\Domains; new-item SERVERNAME; set-location SERVERNAME; new-itemproperty . -Name http -Value 2 -Type DWORD;}"

Based on the information from:

    //push tuple to vector                                                      
    people.push_back(std::make_tuple("Ben", age, profession));                  

    for (const auto& tmppeople: people) {                                       
        std::cout << "Child[" << std::get<0>(tmppeople) << "] = " << "  age : " 
        << std::get<1>(tmppeople) << "\n    profession : " << std::get<2>(tmppeople) << "\n";
    }  
}

Too Long; Don't Read: The difference is whether the source (local) or the destination address/port is being set. In short, bind() set the source and connect() set the destination. Regardless of TCP or UDP.

bind()

bind() set the socket's local (source) address. This is the address where packets are received. Packets sent by the socket carry this as the source address, so the other host will know where to send back its packets.

If receive is not needed the socket source address is useless. Protocols like TCP require receiving enabled in order to send properly, as the destination host send back a confirmation when one or more packets have arrived (i.e. acknowledgement).

connect()

• TCP has a "connected" state. connect() triggers the TCP code to try to establish a connection to the other side.
• UDP has no "connected" state. connect() only set a default address to where packets are sent when no address is specified. When connect() is not used, sendto() or sendmsg() must be used containing the destination address.

When connect() or a send function is called, and no address is bound, Linux automatically bind the socket to a random port. For technical details, take a look at inet_autobind() in Linux kernel source code.

Side notes

• listen() is TCP only.
• In AF_INET family, the socket's source or destination address (struct sockaddr_in) is composed by an IP address (see IP header), and TCP or UDP port (see TCP and UDP header).

allernhwkim originally posted an answer on this question linking to his blog, however a moderator deleted it. It's the only post I've found which doesn't just tell you how to do the same thing with service, provider and factory, but also tells you what you can do with a provider that you can't with a factory, and with a factory that you can't with a service.

Directly from his blog:

app.service('CarService', function() {
   this.dealer="Bad";
    this.numCylinder = 4;
});

app.factory('CarFactory', function() {
    return function(numCylinder) {
      this.dealer="Bad";
        this.numCylinder = numCylinder
    };
});

app.provider('CarProvider', function() {
    this.dealerName = 'Bad';
    this.$get = function() {
        return function(numCylinder) {
            this.numCylinder = numCylinder;
            this.dealer = this.dealerName;
        }
    };
    this.setDealerName = function(str) {
      this.dealerName = str;
    }      
});

This shows how the CarService will always a produce a car with 4 cylinders, you can't change it for individual cars. Whereas CarFactory returns a function so you can do new CarFactory in your controller, passing in a number of cylinders specific to that car. You can't do new CarService because CarService is an object not a function.

The reason factories don't work like this:

app.factory('CarFactory', function(numCylinder) {
      this.dealer="Bad";
      this.numCylinder = numCylinder
});

And automatically return a function for you to instantiate, is because then you can't do this (add things to the prototype/etc):

app.factory('CarFactory', function() {
    function Car(numCylinder) {
        this.dealer="Bad";
        this.numCylinder = numCylinder
    };
    Car.prototype.breakCylinder = function() {
        this.numCylinder -= 1;
    };
    return Car;
});

See how it is literally a factory producing a car.

The conclusion from his blog is pretty good:

In conclusion,

---------------------------------------------------  
| Provider| Singleton| Instantiable | Configurable|
---------------------------------------------------  
| Factory | Yes      | Yes          | No          |
---------------------------------------------------  
| Service | Yes      | No           | No          |
---------------------------------------------------  
| Provider| Yes      | Yes          | Yes         |       
---------------------------------------------------  

1. Use Service when you need just a simple object such as a Hash, for example {foo;1, bar:2} It’s easy to code, but you cannot instantiate it.

2. Use Factory when you need to instantiate an object, i.e new Customer(), new Comment(), etc.

3. Use Provider when you need to configure it. i.e. test url, QA url, production url.

If you find you're just returning an object in factory you should probably use service.

Don't do this:

app.factory('CarFactory', function() {
    return {
        numCylinder: 4
    };
});

Use service instead:

app.service('CarService', function() {
    this.numCylinder = 4;
});

Add reference .dll file to project. Right, Click on Project reference folder --> click on Add Reference -->.Net tab you will find System.Drawing --> click on ok this will add a reference to System.Drawing

This should work fine

$arr = array( 1 => "A", 10 => "B", 5 => "C" );
max(array_keys($arr));

Use the Filter button in the Object Explorer to quickly find a particular object (table, stored procedure, etc.) from partial text in the name or find objects that belong to a particular schema.

It can also be done this way:

figure(xx);
set(gcf, 'name', 'Name goes here')

gcf gets the current figure handle.

easy if its pdf or img use

return (in_Array($file['content-type'], ['image/jpg', 'application/pdf']));

I've been messing around with this for about four hours and decided to share this with you.

You can submit a form by clicking a checkbox but the weird thing is that when checking for the submission in php, you would expect the form to be set when you either check or uncheck the checkbox. But this is not true. The form only gets set when you actually check the checkbox, if you uncheck it it won't be set. the word checked at the end of a checkbox input type will cause the checkbox to display checked, so if your field is checked it will have to reflect that like in the example below. When it gets unchecked the php updates the field state which will cause the word checked the disappear.

You HTML should look like this:

<form method='post' action='#'>
<input type='checkbox' name='checkbox' onChange='submit();'
<?php if($page->checkbox_state == 1) { echo 'checked' }; ?>>
</form>

and the php:

if(isset($_POST['checkbox'])) {
   // the checkbox has just been checked 
   // save the new state of the checkbox somewhere
   $page->checkbox_state == 1;
} else {
   // the checkbox has just been unchecked
   // if you have another form ont the page which uses than you should
   // make sure that is not the one thats causing the page to handle in input
   // otherwise the submission of the other form will uncheck your checkbox
   // so this this line is optional:
      if(!isset($_POST['submit'])) {
          $page->checkbox_state == 0;
      }
}

The above are good suggestions, but you can get at the text value of a cell in a grid view without wrapping it in a literal or label control. You just have to know what event to wire up. In this case, use the DataBound event instead, like so:

protected void GridView1_DataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow)
    {
        if (e.Row.Cells[0].Text.Contains("sometext"))
        {
            e.Row.Cells[0].Font.Bold = true;
        }
    }
}

When running a debugger, you will see the text appear in this method.

Added InstallShield ignores for the build deployment. InstallShield is the new direction Microsoft is headed over Visual Studio Installer, so we've started using it on all new projects. This added line removes the SingleImage installation files. Other InstallShield types may include DVD distribution among others. You may want to add those directory names or just [Ee]xpress/ to prevent any InstallShield LE deployment files from getting into the repo.

Here is our .gitignore for VS2010 C# projects using Install Shield LE with SingleImage deployments for the installer:

You have enabled CORS and enabled Access-Control-Allow-Origin : * in the server.If still you get GET method working and POST method is not working then it might be because of the problem of Content-Type and data problem.

First AngularJS transmits data using Content-Type: application/json which is not serialized natively by some of the web servers (notably PHP). For them we have to transmit the data as Content-Type: x-www-form-urlencoded

Example :-

        $scope.formLoginPost = function () {
            $http({
                url: url,
                method: "POST",
                data: $.param({ 'username': $scope.username, 'Password': $scope.Password }),
                headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
            }).then(function (response) {
                // success
                console.log('success');
                console.log("then : " + JSON.stringify(response));
            }, function (response) { // optional
                // failed
                console.log('failed');
                console.log(JSON.stringify(response));
            });
        };

Note : I am using $.params to serialize the data to use Content-Type: x-www-form-urlencoded. Alternatively you can use the following javascript function

function params(obj){
    var str = "";
    for (var key in obj) {
        if (str != "") {
            str += "&";
        }
        str += key + "=" + encodeURIComponent(obj[key]);
    }
    return str;
}

and use params({ 'username': $scope.username, 'Password': $scope.Password }) to serialize it as the Content-Type: x-www-form-urlencoded requests only gets the POST data in username=john&Password=12345 form.

Just add the following rules to the parent element:

display: flex;
justify-content: center; /* align horizontal */
align-items: center; /* align vertical */

Here's a sample demo (Resize window to see the image align)

Browser support for Flexbox nowadays is quite good.

For cross-browser compatibility for display: flex and align-items, you can add the older flexbox syntax as well:

display: -webkit-box;
display: -webkit-flex;
display: -moz-box;
display: -ms-flexbox;
display: flex;
-webkit-flex-align: center;
-ms-flex-align: center;
-webkit-align-items: center;
align-items: center;

Try this piece of code, rather than ObjectInputStream.

BufferedReader in = new BufferedReader (new InputStreamReader (socket.getInputStream ()));
while (true)
{
    String cominginText = "";
    try
    {
        cominginText = in.readLine ();
        System.out.println (cominginText);
    }
    catch (IOException e)
    {
        //error ("System: " + "Connection to server lost!");
        System.exit (1);
        break;
    }
}

Yes this is possible, however not convenient as Jens said. Using Next generation load balancers like Alteon, which Uses a proprietary protocol called DSSP(Distributed site state Protocol) which performs regular site checks to make sure that the service is available both Locally or Globally i.e different geographical areas. You need to however in your Master DNS to delegate the URL or Service to the device by configuring it as an Authoritative Name Server for that IP or Service. By doing this, the device answers DNS queries where it will resolve the IP that has a service by Round-Robin or is not congested according to how you have chosen from several metrics.

Expected situation

# Wrong output from cell_values()
42884.0

# Expected output
2017-5-29

Example: Let cell_values(2,2) from sheet number 0 will be the date targeted

Get the required variables as the following

workbook = xlrd.open_workbook("target.xlsx")

sheet = workbook.sheet_by_index(0)

wrongValue = sheet.cell_value(2,2)

And make use of xldate_as_tuple

y, m, d, h, i, s = xlrd.xldate_as_tuple(wrongValue, workbook.datemode)
print("{0} - {1} - {2}".format(y, m, d))

That's my solution

We can directly specify the destination file with the dest option now. In the below example, the output json is stored into the /tmp/repo_version_file

- name: Get repository file repo_version model to set ambari_managed_repositories=false
  uri:
    url: 'http://<server IP>:8080/api/v1/stacks/HDP/versions/3.1/repository_versions/1?fields=operating_systems/*'
    method: GET
    force_basic_auth: yes
    user: xxxxx
    password: xxxxx
    headers:
      "X-Requested-By": "ambari"
      "Content-type": "Application/json"
    status_code: 200
    dest: /tmp/repo_version_file

You should build your own Authorize-filter attribute.

Here's mine to study ;)

Public Class RequiresRoleAttribute : Inherits ActionFilterAttribute
    Private _role As String

    Public Property Role() As String
        Get
            Return Me._role
        End Get
        Set(ByVal value As String)
            Me._role = value
        End Set
    End Property

    Public Overrides Sub OnActionExecuting(ByVal filterContext As System.Web.Mvc.ActionExecutingContext)
        If Not String.IsNullOrEmpty(Me.Role) Then
            If Not filterContext.HttpContext.User.Identity.IsAuthenticated Then
                Dim redirectOnSuccess As String = filterContext.HttpContext.Request.Url.AbsolutePath
                Dim redirectUrl As String = String.Format("?ReturnUrl={0}", redirectOnSuccess)
                Dim loginUrl As String = FormsAuthentication.LoginUrl + redirectUrl

                filterContext.HttpContext.Response.Redirect(loginUrl, True)
            Else
                Dim hasAccess As Boolean = filterContext.HttpContext.User.IsInRole(Me.Role)
                If Not hasAccess Then
                    Throw New UnauthorizedAccessException("You don't have access to this page. Only " & Me.Role & " can view this page.")
                End If
            End If
        Else
            Throw New InvalidOperationException("No Role Specified")
        End If

    End Sub
End Class

You can add a RedirectViewController like:

@Configuration
public class WebConfiguration implements WebMvcConfigurer {

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addRedirectViewController("/", "/index.html");
    }
}

From http://www.rueckstiess.net/research/snippets/show/ca1d7d90 and http://qingkaikong.blogspot.com/2016/12/python-parallel-method-in-class.html

We can make an external function and seed it with the class self object:

from joblib import Parallel, delayed
def unwrap_self(arg, **kwarg):
    return square_class.square_int(*arg, **kwarg)

class square_class:
    def square_int(self, i):
        return i * i

    def run(self, num):
        results = []
        results = Parallel(n_jobs= -1, backend="threading")\
            (delayed(unwrap_self)(i) for i in zip([self]*len(num), num))
        print(results)

OR without joblib:

from multiprocessing import Pool
import time

def unwrap_self_f(arg, **kwarg):
    return C.f(*arg, **kwarg)

class C:
    def f(self, name):
        print 'hello %s,'%name
        time.sleep(5)
        print 'nice to meet you.'

    def run(self):
        pool = Pool(processes=2)
        names = ('frank', 'justin', 'osi', 'thomas')
        pool.map(unwrap_self_f, zip([self]*len(names), names))

if __name__ == '__main__':
    c = C()
    c.run()

I had similar problem with the data frame:

group time weight.loss
1 Control  wl1    4.500000
2    Diet  wl1    5.333333
3  DietEx  wl1    6.200000
4 Control  wl2    3.333333
5    Diet  wl2    3.916667
6  DietEx  wl2    6.100000
7 Control  wl3    2.083333
8    Diet  wl3    2.250000
9  DietEx  wl3    2.200000

I think the variable for x axis should be numeric, so that geom_line knows how to connect the points to draw the line.

after I change the 2nd column to numeric:

 group time weight.loss
1 Control    1    4.500000
2    Diet    1    5.333333
3  DietEx    1    6.200000
4 Control    2    3.333333
5    Diet    2    3.916667
6  DietEx    2    6.100000
7 Control    3    2.083333
8    Diet    3    2.250000
9  DietEx    3    2.200000

then it works.

$('html').on('click.popover', function (e) {
    var allpopins = $('.popover.in');
    if (allpopins.has(e.target).length > 0 &&
        !$('.btn', allpopins).is(e.target))
        return;
    // recognise pop-up 
    var id = $(e.target).attr('aria-describedby');
    var popin = $("#" + id);
    //on any button click in entire pop-up hide this pop-ups
    $(popin).on(".btn", function () { popin.remove(); });
    // on any place out of entire popup hide all pop-ups 
    $('.popover.in').not(popin).remove();
});

This is my the best performance solution. Cheers.

Well you can remove the third calendar instance.

GregorianCalendar c1 = new GregorianCalendar();
GregorianCalendar c2 = new GregorianCalendar();
c1.set(2000, 1, 1);
c2.set(2010,1, 1);
c2.add(GregorianCalendar.MILLISECOND, -1 * c1.getTimeInMillis());

The others have already said that methods in onClick are searched in activities, not fragments. Nevertheless, if you really want it, it is possible.

Basically, each view has a tag (probably null). We set the root view's tag to the fragment that inflated that view. Then, it is easy to search the view parents and retrieve the fragment containing the clicked button. Now, we find out the method name and use reflection to call the same method from the retrieved fragment. Easy!

in a class that extends Fragment:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_id, container, false);

    OnClickFragments.registerTagFragment(rootView, this); // <========== !!!!!

    return rootView;
}

public void onButtonSomething(View v) {
    Log.d("~~~","~~~ MyFragment.onButtonSomething");
    // whatever
}

all activities are derived from the same ButtonHandlingActivity:

public class PageListActivity extends ButtonHandlingActivity

ButtonHandlingActivity.java:

public class ButtonHandlingActivity extends Activity {

    public void onButtonSomething(View v) {
        OnClickFragments.invokeFragmentButtonHandlerNoExc(v);
//or, if you want to handle exceptions:
//      try {
//          OnClickFragments.invokeFragmentButtonHandler(v);
//      } catch ...
    }

}

It has to define methods for all xml onClick handlers.

com/example/customandroid/OnClickFragments.java:

package com.example.customandroid;

import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import android.app.Fragment;
import android.view.View;

public abstract class OnClickFragments {
    public static class FragmentHolder {
        Fragment fragment;
        public FragmentHolder(Fragment fragment) {
            this.fragment = fragment;
        }
    }
    public static Fragment getTagFragment(View view) {
        for (View v = view; v != null; v = (v.getParent() instanceof View) ? (View)v.getParent() : null) {
            Object tag = v.getTag();
            if (tag != null && tag instanceof FragmentHolder) {
                return ((FragmentHolder)tag).fragment;
            }
        }
        return null;
    }
    public static String getCallingMethodName(int callsAbove) {
        Exception e = new Exception();
        e.fillInStackTrace();
        String methodName = e.getStackTrace()[callsAbove+1].getMethodName();
        return methodName;
    }
    public static void invokeFragmentButtonHandler(View v, int callsAbove) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
        String methodName = getCallingMethodName(callsAbove+1);
        Fragment f = OnClickFragments.getTagFragment(v);
        Method m = f.getClass().getMethod(methodName, new Class[] { View.class });
        m.invoke(f, v);
    }
    public static void invokeFragmentButtonHandler(View v) throws IllegalAccessException, IllegalArgumentException, InvocationTargetException, NoSuchMethodException {
        invokeFragmentButtonHandler(v,1);
    }
    public static void invokeFragmentButtonHandlerNoExc(View v) {
        try {
            invokeFragmentButtonHandler(v,1);
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (InvocationTargetException e) {
            e.printStackTrace();
        }
    }
    public static void registerTagFragment(View rootView, Fragment fragment) {
        rootView.setTag(new FragmentHolder(fragment));
    }
}

And the next adventure will be proguard obfuscation...

PS

It is of course up to you to design your application so that the data live in the Model rather than in Activities or Fragments (which are Controllers from the MVC, Model-View-Controller point of view). The View is what you define via xml, plus the custom view classes (if you define them, most people just reuse what already is). A rule of thumb: if some data definitely must survive the screen turn, they belong to Model.

Efficient solution using date as background dedicated process

In order to make this kind of translation a lot quicker...

Intro

In this post, you will find

• a Quick Demo, following this,
• some Explanations,
• a Function useable for many Un*x tools (bc, rot13, sed...).

Quick Demo

fifo=$HOME/.fifoDate-$$
mkfifo $fifo
exec 5> >(exec stdbuf -o0 date -f - +%s >$fifo 2>&1)
echo now 1>&5
exec 6< $fifo
rm $fifo
read -t 1 -u 6 now
echo $now

This must output current UNIXTIME. From there, you could compare

time for i in {1..5000};do echo >&5 "now" ; read -t 1 -u6 ans;done
real    0m0.298s
user    0m0.132s
sys     0m0.096s

and:

time for i in {1..5000};do ans=$(date +%s -d "now");done 
real    0m6.826s
user    0m0.256s
sys     0m1.364s

From more than 6 seconds to less than a half second!!(on my host).

You could check echo $ans, replace "now" by "2019-25-12 20:10:00" and so on...

Optionaly, you could, once requirement of date subprocess ended:

exec 5>&- ; exec 6<&-

Instead of running 1 fork by date to convert, run date just 1 time and do all convertion with same process (this could become a lot quicker)!:

date -f - +%s <<eof
Apr 17  2014
May 21  2012
Mar  8 00:07
Feb 11 00:09
eof
1397685600
1337551200
1520464020
1518304140

Sample:

start1=$(LANG=C ps ho lstart 1)
start2=$(LANG=C ps ho lstart $$)
dirchg=$(LANG=C date -r .)
read -p "A date: " userdate
{ read start1 ; read start2 ; read dirchg ; read userdate ;} < <(
   date -f - +%s <<<"$start1"$'\n'"$start2"$'\n'"$dirchg"$'\n'"$userdate" )

Then now have a look:

declare -p start1 start2 dirchg userdate

(may answer something like:

declare -- start1="1518549549"
declare -- start2="1520183716"
declare -- dirchg="1520601919"
declare -- userdate="1397685600"

This was done in one execution!

Using long running subprocess

We just need one fifo:

mkfifo /tmp/myDateFifo
exec 7> >(exec stdbuf -o0 /bin/date -f - +%s >/tmp/myDateFifo)
exec 8</tmp/myDateFifo
rm /tmp/myDateFifo

(Note: As process is running and all descriptors are opened, we could safely remove fifo's filesystem entry.)

Then now:

LANG=C ps ho lstart 1 $$ >&7
read -u 8 start1
read -u 8 start2
LANG=C date -r . >&7
read -u 8 dirchg

read -p "Some date: " userdate
echo >&7 $userdate
read -u 8 userdate

We could buid a little function:

mydate() {
    local var=$1;
    shift;
    echo >&7 $@
    read -u 8 $var
}

mydate start1 $(LANG=C ps ho lstart 1)
echo $start1

Or use my newConnector function

With functions for connecting MySQL/MariaDB, PostgreSQL and SQLite...

You may find them in different version on GitHub, or on my site: download or show.

wget https://raw.githubusercontent.com/F-Hauri/Connector-bash/master/shell_connector.bash

. shell_connector.bash 
newConnector /bin/date '-f - +%s' @0 0

myDate "2018-1-1 12:00" test
echo $test
1514804400

Nota: On GitHub, functions and test are separated files. On my site test are run simply if this script is not sourced.

# Exit here if script is sourced
[ "$0" = "$BASH_SOURCE" ] || { true;return 0;}

You need #include<string> to use string AND #include<iostream> to use cin and cout. (I didn't get it when I read the answers). Here's some code which works:

#include<string>
#include<iostream>
using namespace std;

int main()
{
    string name;
    cin >> name;
    string message("hi");
    cout << name << message;
    return 0;
}

This is ssh certificate store issue. You need to download the valid certificate pem file from target CA website, and then build the soft link file to instruct ssl the trusted certifacate.

openssl x509 -hash -noout -in DigiCert_Global_Root_G3.pem

you will get dd8e9d41

build solf link with hash number and suffix the file with a .0 (dot-zero)

dd8e9d41.0

Then try again.

This code worked well with new version (v0.8.12) (2019-05-21)

$('#summernote').summernote({
        callbacks: {
            onImageUpload: function(files) {
                for(let i=0; i < files.length; i++) {
                    $.upload(files[i]);
                }
            }
        },
        height: 500,
    });

    $.upload = function (file) {
        let out = new FormData();
        out.append('file', file, file.name);

        $.ajax({
            method: 'POST',
            url: 'upload.php',
            contentType: false,
            cache: false,
            processData: false,
            data: out,
            success: function (img) {
                $('#summernote').summernote('insertImage', img);
            },
            error: function (jqXHR, textStatus, errorThrown) {
                console.error(textStatus + " " + errorThrown);
            }
        });
    };

PHP Code (upload.php)

if ($_FILES['file']['name']) {
 if (!$_FILES['file']['error']) {
    $name = md5(rand(100, 200));
    $ext = explode('.', $_FILES['file']['name']);
    $filename = $name . '.' . $ext[1];
    $destination = 'images/' . $filename; //change this directory
    $location = $_FILES["file"]["tmp_name"];
    move_uploaded_file($location, $destination);
    echo 'images/' . $filename;//change this URL
 }
 else
 {
  echo  $message = 'Ooops!  Your upload triggered the following error:  '.$_FILES['file']['error'];
 }
}

It's possible.

Solution 1

From an arcticle on TrueAffection.net.

• Download PCKeyboardHack and install it.
• Go to PCKeyboardHack in System Preferences.
• Enable ‘Change Caps Lock’ and set the keycode to 53.

Solution 2

This solution doesn't involve patching the keyboard driver, but gives you a Vim specific solution.

OS X supports mapping the Caps Lock key to a whole bunch of keys, but you have to do it 'by hand', editting .plist files. The process is described in this article. As addendum to that hint I suggest you first set Caps-Lock to None in the System Preferences, then you only need to change one value in the .plist file. Also, you can of course use the Property List Editor instead of going through the XML conversion steps.

The trick is to map the Caps Lock key to the Help key (code 6), which isn't on most keyboards. But if it is, it will be treated as the insert key, which you probably don't use anyway, since you ask about remapping your Caps Lock to prevent stretching your hands ;)

You can then map the Help and the Insert key to Esc in vim.

map  <Help> <Esc>
map! <Help> <Esc>
map  <Insert> <Esc>
map! <Insert> <Esc>

This will work for gvim (Vim.app). I didn't get it to work with vim in the Terminal and I haven't tested it with MacVim.

So, it's rather a complicated, half-baked solution or installing a third-party piece of hackery. Your pick ;)

Edit: Just noticed solution 3, if you're using MacVim you can use Ctrl, Option and Command as Esc. With the System Preferences it's trivial to map Caps Lock to one of those keys.

public class Test{  
  static {
    loadProperties();
}
   static Properties prop;
   private static void loadProperties() {
    prop = new Properties();
    InputStream in = Test.class
            .getResourceAsStream("test.properties");
    try {
        prop.load(in);
        in.close();
    } catch (IOException e) {
        e.printStackTrace();
    }

}

For my fellow Googlers out there, here's a very simple plug-and-play solution that worked for me after struggling with the more complex solutions for a while:

SELECT
distinct empName,
NewColumnName=STUFF((SELECT ','+ CONVERT(VARCHAR(10), projID ) 
                     FROM returns 
                     WHERE empName=t.empName FOR XML PATH('')) , 1 , 1 , '' )
FROM 
returns t

Notice that I had to convert the ID into a VARCHAR in order to concatenate it as a string. If you don't have to do that, here's an even simpler version:

SELECT
distinct empName,
NewColumnName=STUFF((SELECT ','+ projID
                     FROM returns 
                     WHERE empName=t.empName FOR XML PATH('')) , 1 , 1 , '' )
FROM 
returns t

Throwing in a late contribution:

^(?!\.)((^|\.)([1-9]?\d|1\d\d|2(5[0-5]|[0-4]\d))){4}$

Of the answers I checked, they're either longer or incomplete in their verification. Longer, in my experience, means harder to overlook and therefore more prone to be erroneous. And I like to avoid repeating similar patters, for the same reason.

The main part is, of course, the test for a number - 0 to 255, but also making sure it doesn't allow initial zeroes (except for when it's a single one):

[1-9]?\d|1\d\d|2(5[0-5]|[0-4]\d)

Three alternations - one for sub 100: [1-9]?\d, one for 100-199: 1\d\d and finally 200-255: 2(5[0-5]|[0-4]\d).

This is preceded by a test for start of line or a dot ., and this whole expression is tested for 4 times by the appended {4}.

This complete test for four byte representations is started by testing for start of line followed by a negative look ahead to avoid addresses starting with a .: ^(?!\.), and ended with a test for end of line ($).

See some samples here at regex101.

I'm inclined to agree with Qwertman that it's not currently possible to specify color for text in GitHub markdown, at least not through HTML.

GitHub does allow some HTML elements and attributes, but only certain ones (see their documentation about their HTML sanitization). They do allow p and div tags, as well as color attribute. However, when I tried using them in a markdown document on GitHub, it didn't work. I tried the following (among other variations), and they didn't work:

• <p style='color:red'>This is some red text.</p>
• <font color="red">This is some text!</font>
• These are <b style='color:red'>red words</b>.

As Qwertman suggested, if you really must use color you could do it in a README.html and refer them to it.

it's very easy code .. but hard to fined..

detailsApp.controller("SchoolCtrl", function ($scope, $location) { 
      $scope.addSchool = function () {

        location.href='/ManageSchool/TeacherProfile?ID=' + $scope.TeacherID;
      }
});

if the variable is :

int foo;

in the 2nd C file you declare:

extern int foo;

Just as an extra to anyone using the above answers that implement:

ObjectType instance = (ObjectType)Activator.CreateInstance(objectType);

Be careful - if your Constructor isn't "Public" then you will get the following error:

"System.MissingMethodException: 'No parameterless constructor defined for this object."

Your class can be Internal/Friend, or whatever you need but the constructor must be public.

In my case, I have added the same custom component as a prop instead of actual prob

   import AddAddress from '../../components/Manager/AddAddress';
    
    class Add extends React.PureComponent {
      render() {
        const {
          history,
          addressFormData,
          formErrors,
          addressChange,
          addAddress,
          isDefault,
          defaultChange
        } = this.props;
    

Error:

    return (
        <AddAddress
          addressFormData={addressFormData}
          formErrors={formErrors}
          addressChange={addressChange}
          addAddress={AddAddress} // here i have used the Component name as probs in same component itself instead of prob
          isDefault={isDefault}
          defaultChange={defaultChange}
        />
      </SubPage>

Solution:

return (
    <AddAddress
      addressFormData={addressFormData}
      formErrors={formErrors}
      addressChange={addressChange}
      addAddress={addAddress} // removed the component name and give prob name
      isDefault={isDefault}
      defaultChange={defaultChange}
    />
  </SubPage>

int fib(int x) 
{
    if (x < 2)
      return x;
    else 
      return (fib(x - 1) + fib(x - 2));
}

As mentioned in a comment above, you can have expressions within the template strings/literals. Example:

const one = 1;_x000D_
const two = 2;_x000D_
const result = `One add two is ${one + two}`;_x000D_
console.log(result); // output: One add two is 3

Yes, this is possible. One of the main pros for using Swing is the ease with which the abstract controls can be created and manipulates.

Here is a quick and dirty way to extend the existing JButton class to draw a circle to the right of the text.

package test;

import java.awt.Color;
import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.Graphics;

import javax.swing.JButton;
import javax.swing.JFrame;

public class MyButton extends JButton {

    private static final long serialVersionUID = 1L;

    private Color circleColor = Color.BLACK;

    public MyButton(String label) {
        super(label);
    }

    @Override
    protected void paintComponent(Graphics g) {
        super.paintComponent(g);

        Dimension originalSize = super.getPreferredSize();
        int gap = (int) (originalSize.height * 0.2);
        int x = originalSize.width + gap;
        int y = gap;
        int diameter = originalSize.height - (gap * 2);

        g.setColor(circleColor);
        g.fillOval(x, y, diameter, diameter);
    }

    @Override
    public Dimension getPreferredSize() {
        Dimension size = super.getPreferredSize();
        size.width += size.height;
        return size;
    }

    /*Test the button*/
    public static void main(String[] args) {
        MyButton button = new MyButton("Hello, World!");

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(400, 400);

        Container contentPane = frame.getContentPane();
        contentPane.setLayout(new FlowLayout());
        contentPane.add(button);

        frame.setVisible(true);
    }

}

Note that by overriding paintComponent that the contents of the button can be changed, but that the border is painted by the paintBorder method. The getPreferredSize method also needs to be managed in order to dynamically support changes to the content. Care needs to be taken when measuring font metrics and image dimensions.

For creating a control that you can rely on, the above code is not the correct approach. Dimensions and colours are dynamic in Swing and are dependent on the look and feel being used. Even the default Metal look has changed across JRE versions. It would be better to implement AbstractButton and conform to the guidelines set out by the Swing API. A good starting point is to look at the javax.swing.LookAndFeel and javax.swing.UIManager classes.

http://docs.oracle.com/javase/8/docs/api/javax/swing/LookAndFeel.html

http://docs.oracle.com/javase/8/docs/api/javax/swing/UIManager.html

Understanding the anatomy of LookAndFeel is useful for writing controls: Creating a Custom Look and Feel

try {
    OkHttpClient client = new OkHttpClient();
    Request request = new Request.Builder()
        .url(urls[0])
        .build();
    Response responses = null;

    try {
        responses = client.newCall(request).execute();
    } catch (IOException e) {
        e.printStackTrace();
    }
    String jsonData = responses.body().string();
    JSONObject Jobject = new JSONObject(jsonData);
    JSONArray Jarray = Jobject.getJSONArray("employees");

    for (int i = 0; i < Jarray.length(); i++) {
        JSONObject object     = Jarray.getJSONObject(i);
    }
}

Example add to your columns:

JCol employees  = new employees();
colums.Setid(object.getInt("firstName"));
columnlist.add(lastName);           

They are 3 ways you can achieve this using the py command (py-launcher) in python 3, virtual environment or configuring your default python system path. For illustration purpose, you may see tutorial https://www.youtube.com/watch?v=ynDlb0n27cw&t=38s

Just spent more than hour trying to find out why my view property is not set in my view controller upon initiating it from nib. Remember to call "[super initWithNibName...]" inside your view controller's initWithNibName.

The function is max. To obtain the first maximum value you should do

[val, idx] = max(a);

val is the maximum value and idx is its index.

I tried to do in a NSObject Class and this worked for me:

DispatchQueue.main.asyncAfter(deadline: .now() + .milliseconds(300)) {  
print("Bang!") }

This could also occur if you refer to a variable in the data.frame that doesn't exist. For example, recently I forgot to tell ddply to summarize by one of my variables that I used in geom_line to specify line color. Then, ggplot didn't know where to find the variable I hadn't created in the summary table, and I got this error.

Try this, it works for me:

var storage = null;
setLocalStorage();

function setLocalStorage() {
    storage = (localStorage ? localStorage : (window.content.localStorage ? window.content.localStorage : null));

    try {
        storage.setItem('test_key', 'test_value');//verify if posible saving in the current storage
    }
    catch (e) {
        if (e.name == "NS_ERROR_FILE_CORRUPTED") {
            storage = sessionStorage ? sessionStorage : null;//set the new storage if fails
        }
    }
}

I am just adding another thing, In case you just want to check whether anything is created in JSONObject or not you can use length(), because by default when JSONObject is initialized and no key is inserted, it just has empty braces {} and using has(String key) doesn't make any sense.

So you can directly write if (jsonObject.length() > 0) and do your things.

Happy learning!

I agree with @annakata that this question needs some more clarification, but here is a very, very basic example of how to setup an onclick event handler for the radio buttons:

<html>
 <head>
  <script type="text/javascript">
    window.onload = function() {

        var ex1 = document.getElementById('example1');
        var ex2 = document.getElementById('example2');
        var ex3 = document.getElementById('example3');

        ex1.onclick = handler;
        ex2.onclick = handler;
        ex3.onclick = handler;

    }

    function handler() {
        alert('clicked');
    }
  </script>
 </head>
 <body>
  <input type="radio" name="example1" id="example1" value="Example 1" />
  <label for="example1">Example 1</label>
  <input type="radio" name="example2" id="example2" value="Example 2" />
  <label for="example1">Example 2</label>
  <input type="radio" name="example3" id="example3" value="Example 3" />
  <label for="example1">Example 3</label>
 </body>
</html>

None of the above responses are working for error that has no body but still has some describing text. For me, it was SSL certificate problem: unable to get local issuer certificate error. So I looked right into the code, because doc does't really say much, and did this (in Guzzle 7.1):

try {
    // call here
} catch (\GuzzleHttp\Exception\RequestException $e) {
    if ($e->hasResponse()) {
        $response = $e->getResponse();
        // message is in $response->getReasonPhrase()
    } else {
        $response = $e->getHandlerContext();
        if (isset($response['error'])) {
            // message is in $response['error']
        } else {
            // Unknown error occured!
        }
    }
}

In addition to the answer given by @ramin, if you already have BufferedReader or InputStream, it's possible to iterate through lines like this:

reader.lines().forEach(line -> {
    //...
});

or if you need to process it with given order:

reader.lines().forEachOrdered(line -> {
    //...
});

A dplyr solution:

library(dplyr)
ID <- c(1,1,1,2,2,2,2,3,3)
Value <- c(2,3,5,2,5,8,17,3,5)
Event <- c(1,1,2,1,2,1,2,2,2)
group <- data.frame(Subject=ID, pt=Value, Event=Event)

group %>%
    group_by(Subject) %>%
    summarize(max.pt = max(pt))

This yields the following data frame:

  Subject max.pt
1       1      5
2       2     17
3       3      5

Some DateTime StringFormat samples I found useful. Lifted from C# Examples

DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);

String.Format("{0:y yy yyy yyyy}", dt);  // "8 08 008 2008"   year
String.Format("{0:M MM MMM MMMM}", dt);  // "3 03 Mar March"  month
String.Format("{0:d dd ddd dddd}", dt);  // "9 09 Sun Sunday" day
String.Format("{0:h hh H HH}",     dt);  // "4 04 16 16"      hour 12/24
String.Format("{0:m mm}",          dt);  // "5 05"            minute
String.Format("{0:s ss}",          dt);  // "7 07"            second
String.Format("{0:f ff fff ffff}", dt);  // "1 12 123 1230"   sec.fraction
String.Format("{0:F FF FFF FFFF}", dt);  // "1 12 123 123"    without zeroes
String.Format("{0:t tt}",          dt);  // "P PM"            A.M. or P.M.
String.Format("{0:z zz zzz}",      dt);  // "-6 -06 -06:00"   time zone

When you write List<String> list = new LinkedList();, compiler produces an "unchecked" warning. You may ignore it, but if you used to ignore these warnings you may also miss a warning that notifies you about a real type safety problem.

So, it's better to write a code that doesn't generate extra warnings, and diamond operator allows you to do it in convenient way without unnecessary repetition.

Although manually initialize Firebase with FirebaseApp.initializeApp(this); makes the error disappear, it doesn't fix the root cause, some odd issues come together doesn't seem to be solved, such as

• FCM requires com.google.android.c2dm.permission.RECEIVE permission which is only for GCM
• token becomes unregistered after first notification sent
• message not received/ onMessageReceived() never get called,

Use newer Gradle plugin (e.g. Android plugin 2.2.3 and Gradle 2.14.1) fixed everything. (Of course setup has to be correct as per Firebase documentation )

What you can do is use nltk to tokenize words and then store all of the words in a list, here's what I did. If you don't know nltk; it stands for natural language toolkit and is used to process natural language. Here's some resource if you wanna get started [http://www.nltk.org/book/]

import nltk 
from nltk.tokenize import word_tokenize 
file = open("abc.txt",newline='')
result = file.read()
words = word_tokenize(result)
for i in words:
       print(i)

The output will be this:

09807754
18
n
03
aristocrat
0
blue_blood
0
patrician

You can always do something like this:

update  mytable t
set     SomeColumn = c.ComputedValue
from    (select *, 42 as ComputedValue from mytable where id = 1) c
where t.id = c.id 

You can now also use with statement inside update

update  mytable t
set     SomeColumn = c.ComputedValue
from    (with abc as (select *, 43 as ComputedValue_new from mytable where id = 1
         select *, 42 as ComputedValue, abc.ComputedValue_new  from mytable n1
           inner join abc on n1.id=abc.id) c
where t.id = c.id 

At least in Firefox (as of v24) and Chrome (as of v30), when applied to content in a table element:

word-wrap:break-word

will not actually cause long words to wrap, which can result in the table exceeding the bounds of its container;

word-break:break-all

will result in words wrapping, and the table fitting within its container.

The old tried and true

mkdir /tmp/qq >/dev/null 2>&1

will do what you want with none of the race conditions many of the other solutions have.

Sometimes the simplest (and ugliest) solutions are the best.

The globals() function returns a dictionary containing all your global variables.

>>> apple = 1
>>> banana = 'f'
>>> carrot = 3
>>> globals()
{'carrot': 3, 'apple': 1, '__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', '__doc__': None, 'banana': 'f'}

There is also a similar function called locals().

I realise this is probably not exactly what you want, but it may provide some insight into how Python provides access to your variables.

Edit: It sounds like your problem may be better solved by simply using a dictionary in the first place:

fruitdict = {}
fruitdict['apple'] = 1
fruitdict['banana'] = 'f'
fruitdict['carrot'] = 3

Since 2005, Mozilla browsers such as Firefox have supported the non-standard :-moz-broken CSS pseudo-class that can accomplish exactly this request:

td {_x000D_
  min-width:64px; /* for display purposes so you can see the empty cell */_x000D_
}_x000D_
_x000D_
img[alt]:-moz-broken {_x000D_
  display:none;_x000D_
}

<table border="1"><tr><td>_x000D_
  <img src="error">_x000D_
</td><td>_x000D_
  <img src="broken" alt="A broken image">_x000D_
</td><td>_x000D_
  <img src="https://images-na.ssl-images-amazon.com/images/I/218eLEn0fuL.png"_x000D_
       alt="A bird" style="width: 120px">_x000D_
</td></tr></table>

img[alt]::before also works in Firefox 64 (though once upon a time it was img[alt]::after so this is not reliable). I can't get either of those to work in Chrome 71.

read this;-

http://php.net/manual/en/soapclient.call.php

Or

This is a good example, for the SOAP function "__call". However it is deprecated.

<?php
    $wsdl = "http://webservices.tekever.eu/ctt/?wsdl";
    $int_zona = 5;
    $int_peso = 1001;
    $cliente = new SoapClient($wsdl);
    print "<p>Envio Internacional: ";
    $vem = $cliente->__call('CustoEMSInternacional',array($int_zona, $int_peso));
    print $vem;
    print "</p>";
?>

We had the same problem discussed here.

We have a Redis hash, a key to hash entries (name/value pairs), and we needed to hold individual expiration times on each hash entry.

We implemented this by adding n bytes of prefix data containing encoded expiration information when we write the hash entry values, we also set the key to expire at the time contained in the value being written.

Then, on read, we decode the prefix and check for expiration. This is additional overhead, however, the reads are still O(n) and the entire key will expire when the last hash entry has expired.

You can also use:

Range( RangeName ).end(xlDown).row

to find the last row with data in it starting at your named range.

This tip shows how to use Logger in any java application. Logger needs to configure Formatter and Handler. There are many types of handlers and formatters present. In this example FileHandler is used to store all the log messages in a log file. And Simple formatter is used to format the log messages in human readable form.

package MyProject;

import java.io.IOException;
import java.util.logging.FileHandler;
import java.util.logging.Level;
import java.util.logging.Logger;
import java.util.logging.SimpleFormatter;

public class MyLogger {

  public static void main(String[] args) {

    Logger logger = Logger.getLogger("MyLog");
    FileHandler fh;

    try {

      // This block configure the logger with handler and formatter
      fh = new FileHandler("c:\\MyLogFile.log", true);
      logger.addHandler(fh);
      logger.setLevel(Level.ALL);
      SimpleFormatter formatter = new SimpleFormatter();
      fh.setFormatter(formatter);

      // the following statement is used to log any messages   
      logger.log(Level.WARNING,"My first log");

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

  }

}

some more examples you can find here https://docs.oracle.com/javase/7/docs/api/java/util/logging/Logger.html

May be this will help some one. I have my proxy setup in python script but keep getting the error mentioned in the question.

Below is the piece of block which will take my username and password as a constant in the beginning.

   if (use_proxy):
        proxy = req.ProxyHandler({'https': proxy_url})
        auth = req.HTTPBasicAuthHandler()
        opener = req.build_opener(proxy, auth, req.HTTPHandler)
        req.install_opener(opener)

If you are using corporate laptop and if you did not connect to Direct Access or office VPN then the above block will throw error. All you need to do is to connect to your org VPN and then execute your python script.

• Checkout a working copy of the repository (or at least the subdirectory that you want to add the files to): svn checkout https://example.org/path/to/repo/bleh
• Copy the files over there.
• svn add file1 file2...
• svn commit

I am not aware of a quicker option.

Note: if you are on the same machine as your Subversion repository, the URL can use the file: specifier with a path in place of https: in the svn checkout command. For example svn checkout file:///path/to/repo/bleh.

PS. as pointed out in the comments and other answers, you can use something like svn import . <URL> if you want to recursively import everything in the current directory. With this option, however, you can't skip over some of the files; it's all or nothing.

It suggests to use it, if you are sure that class will always remain singleton.

fs/promises and fs.Dirent

Here's an efficient, non-blocking ls program using Node's fast fs.Dirent objects and fs/promises module. This approach allows you to skip wasteful fs.exist or fs.stat calls on every path -

// main.js
import { readdir } from "fs/promises"
import { join } from "path"

async function* ls (path = ".")
{ yield path
  for (const dirent of await readdir(path, { withFileTypes: true }))
    if (dirent.isDirectory())
      yield* ls(join(path, dirent.name))
    else
      yield join(path, dirent.name)
}

async function* empty () {}

async function toArray (iter = empty())
{ let r = []
  for await (const x of iter)
    r.push(x)
  return r
}

toArray(ls(".")).then(console.log, console.error)

Let's get some sample files so we can see ls working -

$ yarn add immutable     # (just some example package)
$ node main.js

[
  '.',
  'main.js',
  'node_modules',
  'node_modules/.yarn-integrity',
  'node_modules/immutable',

If you develop in Visual Studio 2013 and 2015 versions, you can use their GPU Usage tool:

• GPU Usage Tool in Visual Studio (video) https://www.youtube.com/watch?v=Gjc5bPXGkTE
• GPU Usage Visual Studio 2015 https://msdn.microsoft.com/en-us/library/mt126195.aspx
• GPU Usage tool in Visual Studio 2013 Update 4 CTP1 (blog) http://blogs.msdn.com/b/vcblog/archive/2014/09/05/gpu-usage-tool-in-visual-studio-2013-update-4-ctp1.aspx
• GPU Usage for DirectX in Visual Studio (blog) http://blogs.msdn.com/b/ianhu/archive/2014/12/16/gpu-usage-for-directx-in-visual-studio.aspx

Screenshot from MSDN:

Moreover, it seems you can diagnose any application with it, not only Visual Studio Projects:

In addition to Visual Studio projects you can also collect GPU usage data on any loose .exe applications that you have sitting around. Just open the executable as a solution in Visual Studio and then start up a diagnostics session and you can target it with GPU usage. This way if you are using some type of engine or alternative development environment you can still collect data on it as long as you end up with an executable.

The easiest solution I found was to specify excel version 97-2003 on the connection manager setup.

Here is code based on bestsss' answer:

    Enumeration<URL> en = getClass().getClassLoader().getResources(
            "META-INF");
    List<String> profiles = new ArrayList<>();
    while (en.hasMoreElements()) {
        URL url = en.nextElement();
        JarURLConnection urlcon = (JarURLConnection) (url.openConnection());
        try (JarFile jar = urlcon.getJarFile();) {
            Enumeration<JarEntry> entries = jar.entries();
            while (entries.hasMoreElements()) {
                String entry = entries.nextElement().getName();
                System.out.println(entry);
            }
        }
    }

I use typeof to determine if the variable I'm looking at is an object. If it is then I use instanceof to determine what kind it is

var type = typeof elem;
if (type == "number") {
    // do stuff
}
else if (type == "string") {
    // do stuff
}
else if (type == "object") { // either array or object
    if (elem instanceof Buffer) {
    // other stuff

Linux

To run docker daemon on Linux (from CLI), run:

$ sudo service docker start # Ubuntu/Debian

^{Note: Skip the $ character when copy and pasting.}

On RedHat/CentOS, run: sudo systemctl start docker.

To initialize the "base" filesystem, run:

$ sudo service docker stop
$ sudo rm -rf /var/lib/docker
$ sudo service docker start

or manually like:

$ sudo docker -d --storage-opt dm.basesize=20G

Install docker-machine on Linux

To install machine binaries on Linux:

• locally:

  install -vm755 <(curl -L https://github.com/docker/machine/releases/download/v0.5.3/docker-machine_linux-amd64) $HOME/bin/docker-machine
  

• global:

  sudo bash -c 'install -vm755 <(curl -L https://github.com/docker/machine/releases/download/v0.5.3/docker-machine_linux-amd64) /usr/local/bin/docker-machine'
  

macOS

On macOS the docker binary is only a client and you cannot use it to run the docker daemon, because Docker daemon uses Linux-specific kernel features, therefore you can’t run Docker natively in OS X. So you have to install docker-machine in order to create VM and attach to it.

Install docker-machine on macOS

If you don't have docker-machine command yet, install it by using one of the following methods:

• Using Brew command: brew install docker-machine docker.

• manually from GitHub:

  install -v <(curl https://github.com/docker/machine/releases/download/v0.5.3/docker-machine_linux-amd64) /usr/local/bin/docker-machine
  

See: Get started with Docker for Mac.

Configure docker-machine on macOS

To start Docker Machine via Homebrew, run:

brew services start docker-machine

To create a default machine (if you don't have one, see: docker-machine ls):

docker-machine create --driver virtualbox default

Then set-up the environment for the Docker client:

eval "$(docker-machine env default)"

Then double-check by listing containers:

docker ps

See: Get started with Docker Machine and a local VM.

Install Docker.app on macOS

Alternatively to above solution, you can install a Docker app by:

brew cask install docker

Check this post for more details. See also: Cannot connect to the Docker daemon on macOS

I"m not sure if its too late, but the problem is that, you cannot set the columns in design mode if you are binding at runtime. So if you are binding at runtime, go ahead and remove the columns from the design mode and do it pragmatically

ex..

     if (dt.Rows.Count > 0)
    {
        dataGridViewProjects.DataSource = dt;
        dataGridViewProjects.Columns["Title"].Width = 300;
        dataGridViewProjects.Columns["ID"].Visible = false;
    }

This answer is based on the accepted answer's JavaScript solution. It's mainly just formatted nicer, with longer function names, and of course shorter function syntax because it's in ES6 + CoffeeScript.

JavaScript version (ES6)

distanceSquared = (v, w)=> Math.pow(v.x - w.x, 2) + Math.pow(v.y - w.y, 2);
distance = (v, w)=> Math.sqrt(distanceSquared(v, w));

distanceToLineSegmentSquared = (p, v, w)=> {
    l2 = distanceSquared(v, w);
    if (l2 === 0) {
        return distanceSquared(p, v);
    }
    t = ((p.x - v.x) * (w.x - v.x) + (p.y - v.y) * (w.y - v.y)) / l2;
    t = Math.max(0, Math.min(1, t));
    return distanceSquared(p, {
        x: v.x + t * (w.x - v.x),
        y: v.y + t * (w.y - v.y)
    });
}
distanceToLineSegment = (p, v, w)=> {
    return Math.sqrt(distanceToLineSegmentSquared(p, v));
}

CoffeeScript version

distanceSquared = (v, w)-> (v.x - w.x) ** 2 + (v.y - w.y) ** 2
distance = (v, w)-> Math.sqrt(distanceSquared(v, w))

distanceToLineSegmentSquared = (p, v, w)->
    l2 = distanceSquared(v, w)
    return distanceSquared(p, v) if l2 is 0
    t = ((p.x - v.x) * (w.x - v.x) + (p.y - v.y) * (w.y - v.y)) / l2
    t = Math.max(0, Math.min(1, t))
    distanceSquared(p, {
        x: v.x + t * (w.x - v.x)
        y: v.y + t * (w.y - v.y)
    })

distanceToLineSegment = (p, v, w)->
    Math.sqrt(distanceToLineSegmentSquared(p, v, w))

One liner error raising can be done with assert statements if that's what you want to do. This will help you write statically fixable code and check errors early.

assert type(A) is type(""), "requires a string"

This one uses PATINDEX to match ids from a table to a non-digit delimited integer list.

-- Given a string @myList containing character delimited integers 
-- (supports any non digit delimiter)
DECLARE @myList VARCHAR(MAX) = '1,2,3,4,42'

SELECT * FROM [MyTable]
    WHERE 
        -- When the Id is at the leftmost position 
        -- (nothing to its left and anything to its right after a non digit char) 
        PATINDEX(CAST([Id] AS VARCHAR)+'[^0-9]%', @myList)>0 
        OR
        -- When the Id is at the rightmost position
        -- (anything to its left before a non digit char and nothing to its right) 
        PATINDEX('%[^0-9]'+CAST([Id] AS VARCHAR), @myList)>0
        OR
        -- When the Id is between two delimiters 
        -- (anything to its left and right after two non digit chars)
        PATINDEX('%[^0-9]'+CAST([Id] AS VARCHAR)+'[^0-9]%', @myList)>0
        OR
        -- When the Id is equal to the list
        -- (if there is only one Id in the list)
        CAST([Id] AS VARCHAR)=@myList

Notes:

• when casting as varchar and not specifying byte size in parentheses the default length is 30
• % (wildcard) will match any string of zero or more characters
• ^ (wildcard) not to match
• [^0-9] will match any non digit character
• PATINDEX is an SQL standard function that returns the position of a pattern in a string

char * and const unsigned char * are considered unrelated types. So you want to use reinterpret_cast.

But if you were going from const unsigned char* to a non const type you'd need to use const_cast first. reinterpret_cast cannot cast away a const or volatile qualification.

This will let you choose from email, whatsapp or whatever.

try { 
    Intent shareIntent = new Intent(Intent.ACTION_SEND);  
    shareIntent.setType("text/plain");
    shareIntent.putExtra(Intent.EXTRA_SUBJECT, "My application name");
    String shareMessage= "\nLet me recommend you this application\n\n";
    shareMessage = shareMessage + "https://play.google.com/store/apps/details?id=" + BuildConfig.APPLICATION_ID +"\n\n";
    shareIntent.putExtra(Intent.EXTRA_TEXT, shareMessage);  
    startActivity(Intent.createChooser(shareIntent, "choose one"));
} catch(Exception e) { 
    //e.toString();
}   

line=$((${RANDOM} % $(wc -l < /etc/passwd)))
sed -n "${line}p" /etc/passwd

just with your file instead.

In this example I used the file /etc/password, using the special variable ${RANDOM} (about which I learned here), and the sed expression you had, only difference is that I am using double quotes instead of single to allow the variable expansion.

If you want to show/hide an element based on the status of one {{expression}} you can use ng-switch:

<p ng-switch="foo.bar">I could be shown, or I could be hidden</p>

The paragraph will be displayed when foo.bar is true, hidden when false.

This library makes it simple.

Just Call:

PickImageDialog.on(MainActivity.this, new PickSetup(BuildConfig.APPLICATION_ID));

Then make your Activity implement IPickResult and override this below method.

@Override
public void onPickResult(PickResult r) {
    if (r.getError() == null) {
        imageView.setImageBitmap(r.getBitmap());

        //or

        imageView.setImageURI(r.getUri());
    } else {
        //Handle possible errors
        //TODO: do what you have to do with r.getError();
    }
}

drop schema public cascade;

should do the trick.

Here is a more user-friendly answer that still uses streaming.

Just define these functions and call getImage(). It will use the same file name as the url and write to the current directory by default, but both can be changed.

import requests
from StringIO import StringIO
from PIL import Image

def createFilename(url, name, folder):
    dotSplit = url.split('.')
    if name == None:
        # use the same as the url
        slashSplit = dotSplit[-2].split('/')
        name = slashSplit[-1]
    ext = dotSplit[-1]
    file = '{}{}.{}'.format(folder, name, ext)
    return file

def getImage(url, name=None, folder='./'):
    file = createFilename(url, name, folder)
    with open(file, 'wb') as f:
        r = requests.get(url, stream=True)
        for block in r.iter_content(1024):
            if not block:
                break
            f.write(block)

def getImageFast(url, name=None, folder='./'):
    file = createFilename(url, name, folder)
    r = requests.get(url)
    i = Image.open(StringIO(r.content))
    i.save(file)

if __name__ == '__main__':
    # Uses Less Memory
    getImage('http://www.example.com/image.jpg')
    # Faster
    getImageFast('http://www.example.com/image.jpg')

The request guts of getImage() are based on the answer here and the guts of getImageFast() are based on the answer above.

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me

body {
        overflow-y: hidden ! important;
        overflow-x: hidden ! important;
        background-color: #f8f8f8;
        background-image: url('index.png');
        /*background-size: cover;*/
        background-size: contain;
        background-repeat: no-repeat;
        background-position: right;
}

My solution

SET sql_mode='';
UPDATE tnx_k2_items
SET created_by = 790
, modified = '0000-00-00 00:00:00'
, modified_by = 0

SELECT *
FROM tbl_name
WHERE coalesce(id_field,'unik_null_value') 
IN ('value1', 'value2', 'value3', 'unik_null_value')

So that you eliminate the null from the check. Given a null value in id_field, the coalesce function would instead of null return 'unik_null_value', and by adding 'unik_null_value to the IN-list, the query would return posts where id_field is value1-3 or null.

This worked for me. Although i'm curious of the reason I started getting the errors in the first place. When I logged out yesterday, it was fine. Log in this morning, it wasn't.

rm .git/index

git reset

For small apps, I use my own Application Controller for showing, closing and disposing windows and DataContexts. It's a central point in UI of an application.

It's something like this:

//It is singleton, I will just post 2 methods and their invocations
public void ShowNewWindow(Window window, object dataContext = null, bool dialog = true)
{
    window.DataContext = dataContext;
    addToWindowRegistry(dataContext, window);

    if (dialog)
        window.ShowDialog();
    else
        window.Show();

}

public void CloseWindow(object dataContextSender)
{
    var correspondingWindows = windowRegistry.Where(c => c.DataContext.Equals(dataContextSender)).ToList();
    foreach (var pair in correspondingWindows)
    {
        pair.Window.Close();              
    }
}

and their invocations from ViewModels:

// Show new Window with DataContext
ApplicationController.Instance.ShowNewWindow(
                new ClientCardsWindow(),
                new ClientCardsVM(),
                false);

// Close Current Window from viewModel
ApplicationController.Instance.CloseWindow(this);

Of course you can find some restrictions in my solution. Again: I use it for small projects, and it's enough. If you're interested, I can post full code here or somewhere else/

last = Object.keys(obj)[Object.keys(obj).length-1];

where obj is your object

The problem is in the font-weight.
For Font Awesome 5 you have to use {font-weight:900}

If you don't create the DOM yourself (e.g. in a userscript) you can do the following with pure JS:

for ( td of document.querySelectorAll('td') ) {_x000D_
  console.debug("text:", td, td.innerText)_x000D_
  td.setAttribute('text', td.innerText)_x000D_
}_x000D_
for ( td of document.querySelectorAll('td[text="male"]') )_x000D_
  console.debug("male:", td, td.innerText)

<table>_x000D_
  <tr>_x000D_
    <td>Peter</td>_x000D_
    <td>male</td>_x000D_
    <td>34</td>_x000D_
  </tr>_x000D_
  <tr>_x000D_
    <td>Susanne</td>_x000D_
    <td>female</td>_x000D_
    <td>12</td>_x000D_
  </tr>_x000D_
</table>

Console output

text: <td> Peter
text: <td> male
text: <td> 34
text: <td> Susanne
text: <td> female
text: <td> 12
male: <td text="male"> male

Java has Currency class that represents the ISO 4217 currency codes. BigDecimal is the best type for representing currency decimal values.

Joda Money has provided a library to represent money.

It has been a while since this question was posted, but the following code works across all browsers (note although MattPII's answer works in FFox and Chrome, it throws script errors in IE).

$('#foo').dialog({
    autoOpen: true,
    buttons: [
    {
        text: 'OK',
        open: function() { $(this).addClass('b') }, //will append a class called 'b' to the created 'OK' button.
        click: function() { alert('OK Clicked')}
    },
    {
        text: "Cancel",
        click: function() { alert('Cancel Clicked')}
    }
  ]
});

All of the DISPATCH_QUEUE_PRIORITY_X queues are concurrent queues (meaning they can execute multiple tasks at once), and are FIFO in the sense that tasks within a given queue will begin executing using "first in, first out" order. This is in comparison to the main queue (from dispatch_get_main_queue()), which is a serial queue (tasks will begin executing and finish executing in the order in which they are received).

So, if you send 1000 dispatch_async() blocks to DISPATCH_QUEUE_PRIORITY_DEFAULT, those tasks will start executing in the order you sent them into the queue. Likewise for the HIGH, LOW, and BACKGROUND queues. Anything you send into any of these queues is executed in the background on alternate threads, away from your main application thread. Therefore, these queues are suitable for executing tasks such as background downloading, compression, computation, etc.

Note that the order of execution is FIFO on a per-queue basis. So if you send 1000 dispatch_async() tasks to the four different concurrent queues, evenly splitting them and sending them to BACKGROUND, LOW, DEFAULT and HIGH in order (ie you schedule the last 250 tasks on the HIGH queue), it's very likely that the first tasks you see starting will be on that HIGH queue as the system has taken your implication that those tasks need to get to the CPU as quickly as possible.

Note also that I say "will begin executing in order", but keep in mind that as concurrent queues things won't necessarily FINISH executing in order depending on length of time for each task.

As per Apple:

https://developer.apple.com/library/content/documentation/General/Conceptual/ConcurrencyProgrammingGuide/OperationQueues/OperationQueues.html

A concurrent dispatch queue is useful when you have multiple tasks that can run in parallel. A concurrent queue is still a queue in that it dequeues tasks in a first-in, first-out order; however, a concurrent queue may dequeue additional tasks before any previous tasks finish. The actual number of tasks executed by a concurrent queue at any given moment is variable and can change dynamically as conditions in your application change. Many factors affect the number of tasks executed by the concurrent queues, including the number of available cores, the amount of work being done by other processes, and the number and priority of tasks in other serial dispatch queues.

Basically, if you send those 1000 dispatch_async() blocks to a DEFAULT, HIGH, LOW, or BACKGROUND queue they will all start executing in the order you send them. However, shorter tasks may finish before longer ones. Reasons behind this are if there are available CPU cores or if the current queue tasks are performing computationally non-intensive work (thus making the system think it can dispatch additional tasks in parallel regardless of core count).

The level of concurrency is handled entirely by the system and is based on system load and other internally determined factors. This is the beauty of Grand Central Dispatch (the dispatch_async() system) - you just make your work units as code blocks, set a priority for them (based on the queue you choose) and let the system handle the rest.

So to answer your above question: you are partially correct. You are "asking that code" to perform concurrent tasks on a global concurrent queue at the specified priority level. The code in the block will execute in the background and any additional (similar) code will execute potentially in parallel depending on the system's assessment of available resources.

The "main" queue on the other hand (from dispatch_get_main_queue()) is a serial queue (not concurrent). Tasks sent to the main queue will always execute in order and will always finish in order. These tasks will also be executed on the UI Thread so it's suitable for updating your UI with progress messages, completion notifications, etc.

Try WindowsIdentity.GetCurrent(). You need to add reference to System.Security.Principal

if you want to check what it is:

>>>isinstance(1,str)
False
>>>isinstance('stuff',str)
True
>>>isinstance(1,int)
True
>>>isinstance('stuff',int)
False

if you want to get ints from raw_input

>>>x=raw_input('enter thing:')
enter thing: 3
>>>try: x = int(x)
   except: pass

>>>isinstance(x,int)
True

You can use block (/***/) or single line comment (//) for each line. You should use "#" in sh command.

If you want to have two tables next to each other you can use: (with float package loaded)

\begin{table}[H]
 \begin{minipage}{.5\textwidth}
  %first table
 \end{minipage}
 \begin{minipage}{.5\textwidth}
  %second table
 \end{minipage}
\end{table}

Each one will have own caption and number. Another option is subfigure package.

I was recently struggling with a similar problem. It turned out that the database was missing indexes on foreign keys. That caused Oracle to lock many more records than required which quickly led to a deadlock during high concurrency.

Here is an excellent article with lots of good detail, suggestions, and details about how to fix a deadlock: http://www.oratechinfo.co.uk/deadlocks.html#unindex_fk

As of ES5 (when this answer was given):

If you want an empty array of undefined elements, you could simply do

var whatever = new Array(5);

this would give you

[undefined, undefined, undefined, undefined, undefined]

and then if you wanted it to be filled with empty strings, you could do

whatever.fill('');

which would give you

["", "", "", "", ""]

And if you want to do it in one line:

var whatever = Array(5).fill('');

How about this :

@client = TinyTds::Client.new(
      :adapter => 'mysql2',
      :host => 'host',
      :database => 'siteconfig_development',
      :username => 'username',
      :password => 'password'

sql = "SELECT * FROM users"

result = @client.execute(sql)

results.each do |row|
puts row[0]
end

You need to have TinyTds gem installed, since you didn't specify it in your question I didn't use Active Record

Use the if __name__ == '__main__' idiom -- __name__ is a special variable whose value is '__main__' if the module is being run as a script, and the module name if it's imported. So you'd do something like

# imports
# class/function definitions
if __name__ == '__main__':
    # code here will only run when you invoke 'python main.py'

I created a little wrapper around the Screen from System.Windows.Forms, currently everything works... Not sure about the "device independent pixels", though.

public class WpfScreen
{
    public static IEnumerable<WpfScreen> AllScreens()
    {
        foreach (Screen screen in System.Windows.Forms.Screen.AllScreens)
        {
            yield return new WpfScreen(screen);
        }
    }

    public static WpfScreen GetScreenFrom(Window window)
    {
        WindowInteropHelper windowInteropHelper = new WindowInteropHelper(window);
        Screen screen = System.Windows.Forms.Screen.FromHandle(windowInteropHelper.Handle);
        WpfScreen wpfScreen = new WpfScreen(screen);
        return wpfScreen;
    }

    public static WpfScreen GetScreenFrom(Point point)
    {
        int x = (int) Math.Round(point.X);
        int y = (int) Math.Round(point.Y);

        // are x,y device-independent-pixels ??
        System.Drawing.Point drawingPoint = new System.Drawing.Point(x, y);
        Screen screen = System.Windows.Forms.Screen.FromPoint(drawingPoint);
        WpfScreen wpfScreen = new WpfScreen(screen);

        return wpfScreen;
    }

    public static WpfScreen Primary
    {
        get { return new WpfScreen(System.Windows.Forms.Screen.PrimaryScreen); }
    }

    private readonly Screen screen;

    internal WpfScreen(System.Windows.Forms.Screen screen)
    {
        this.screen = screen;
    }

    public Rect DeviceBounds
    {
        get { return this.GetRect(this.screen.Bounds); }
    }

    public Rect WorkingArea
    {
        get { return this.GetRect(this.screen.WorkingArea); }
    }

    private Rect GetRect(Rectangle value)
    {
        // should x, y, width, height be device-independent-pixels ??
        return new Rect
                   {
                       X = value.X,
                       Y = value.Y,
                       Width = value.Width,
                       Height = value.Height
                   };
    }

    public bool IsPrimary
    {
        get { return this.screen.Primary; }
    }

    public string DeviceName
    {
        get { return this.screen.DeviceName; }
    }
}

My problem turned out to be that I was assigning as document.getElementById("myinput").Value = '1';

Notice the capital V in Value? Once I changed it to small case, i.e., value, the data started posting. Odd as it was not giving any JavaScript errors either.

(returnValue != "1" ? false : true);

Python syntax does permit more than one statement on a line, separated by semicolon (;). However, limiting each line to one statement makes it easier for a human to follow a program's logic when reading through it.

So, another way of solving this issue, is to understand why the lint message is there and not put more than one statement on a line.

Yes, you may find it easier to write multiple statements per line, however, Pylint is for every other reader of your code not just you.

just make that

getApplicationContext().getTheme().applyStyle(R.style.Theme_Mc, true);

and In your values/styles.xml add this

 <style  name="Theme.Mc" parent="Theme.AppCompat.Light.NoActionBar">
         <!-- ADD Your Styles  -->


     </style>

If you wish to use "like" as a parameter your link needs to be:

<a href="/topic.php?like=like">Like</a>

More likely though is that you want:

<a href="/topic.php?id=14&like=like">Like</a>

Possible solution is described in this Code Project tip:

As folks mentioned IIS user network service user credentials while trying to log in sql server. So just change the Application pool settings in your IIS:

1. Open Internet Information Service Manager
2. Click on Application Pools in left navigation tree.
3. Select your version Pool. In my case, I am using ASP .Net v4.0. If you dont have this version, select DefaultAppPool.
4. Right click on step 3, and select advanced settings.
5. Select Identity in properties window and click the button to change the value.
6. Select Local System in Built-in accounts combo box and click ok. That's it. Now run your application. Everything works well.

TL; DR

Use std::reference_wrapper like this:

#include <functional>
#include <string>
#include <vector>
#include <iostream>

int main()
{
    std::string hello = "Hello, ";
    std::string world = "everyone!";
    typedef std::vector<std::reference_wrapper<std::string>> vec_t;
    vec_t vec = {hello, world};
    vec[1].get() = "world!";
    std::cout << hello << world << std::endl;
    return 0;
}

Long answer

As standard suggests, for a standard container X containing objects of type T, T must be Erasable from X.

Erasable means that the following expression is well formed:

allocator_traits<A>::destroy(m, p)

A is container's allocator type, m is allocator instance and p is a pointer of type *T. See here for Erasable definition.

By default, std::allocator<T> is used as vector's allocator. With the default allocator, the requirement is equivalent to the validity of p->~T() (Note the T is a reference type and p is pointer to a reference). However, pointer to a reference is illegal, hence the expression is not well formed.

If you KNOW that a function returns a promise, i suggest using the new async/await features in JavaScript. It makes the syntax look synchronous but work asynchronously. When you add the async keyword to a function, it allows you to await promises in that scope:

async function ace() {
  var r = await new Promise((resolve, reject) => {
    resolve(true)
  });

  console.log(r); // true
}

if a function does not return a promise, i recommend wrapping it in a new promise that you define, then resolve the data that you want:

function ajax_call(url, method) {
  return new Promise((resolve, reject) => {
    fetch(url, { method })
    .then(resp => resp.json())
    .then(json => { resolve(json); })
  });
}

async function your_function() {
  var json = await ajax_call('www.api-example.com/some_data', 'GET');
  console.log(json); // { status: 200, data: ... }
}

Bottom line: leverage the power of Promises.
