clear site data in your browser. and it will be fixed. sometimes when you run proxies, vpns or some other programs this error happens.

When you install the WAMPP in your machine by default the password of PhpMyAdmin is blank. so put root in user Section and left blank of password field. hope it works.

Happy Coding!!

Here is a working plunkr with a filter and sortBy pipe. https://plnkr.co/edit/vRvnNUULmBpkbLUYk4uw?p=preview

As developer033 mentioned in a comment, you are passing in a single value to the filter pipe, when the filter pipe is expecting an array of values. I would tell the pipe to expect a single value instead of an array

export class FilterPipe implements PipeTransform {
    transform(items: any[], term: string): any {
        // I am unsure what id is here. did you mean title?
        return items.filter(item => item.id.indexOf(term) !== -1);
    }
}

I would agree with DeborahK that impure pipes should be avoided for performance reasons. The plunkr includes console logs where you can see how much the impure pipe is called.

This occured when I accidentally named my render function incorrectly:

import React from 'react';

export class MyComponent extends React.Component {
  noCalledRender() {
    return (
      <div>
        Hello, world!
      </div>
    );
  }
}

My instance of this error was simply caused because my class did not have a proper render method.

match_parent is not supported, so use android:layout_width="0dp". With 0dp, you can think of your constraints as 'scalable' rather than 'filling whats left'.

Also, 0dp can be defined by a position, where match_parent relies on it's parent for it's position (x,y and width, height)

it is a known issue

I think the workaround should be set it as

.card-img-top {
    width: 100%;
}

You can use:

<input (input)="saverange()>

It might be obvious, but make sure that you are sending to the parser URL object not a String containing www adress. This will not work:

    ObjectMapper mapper = new ObjectMapper();
    String www = "www.sample.pl";
    Weather weather = mapper.readValue(www, Weather.class);

But this will:

    ObjectMapper mapper = new ObjectMapper();
    URL www = new URL("http://www.oracle.com/");
    Weather weather = mapper.readValue(www, Weather.class);

used ast, example

In [15]: a = "[{'start_city': '1', 'end_city': 'aaa', 'number': 1},\
...:      {'start_city': '2', 'end_city': 'bbb', 'number': 1},\
...:      {'start_city': '3', 'end_city': 'ccc', 'number': 1}]"
In [16]: import ast
In [17]: ast.literal_eval(a)
Out[17]:
[{'end_city': 'aaa', 'number': 1, 'start_city': '1'},
 {'end_city': 'bbb', 'number': 1, 'start_city': '2'},
 {'end_city': 'ccc', 'number': 1, 'start_city': '3'}]

If you want to solve it in a two-liner you can do it like this:

with open('data.json') as f:
    data = [json.loads(line) for line in f]

It's worth adding, since the OP's code sample doesn't provide enough context to prove otherwise, but I received this error as well on the following code:

public RetailSale GetByRefersToRetailSaleId(Int32 refersToRetailSaleId)
{
    return GetQueryable()
        .FirstOrDefault(x => x.RefersToRetailSaleId.Equals(refersToRetailSaleId));
}

Apparently, I cannot use Int32.Equals in this context to compare an Int32 with a primitive int; I had to (safely) change to this:

public RetailSale GetByRefersToRetailSaleId(Int32 refersToRetailSaleId)
{
    return GetQueryable()
      .FirstOrDefault(x => x.RefersToRetailSaleId == refersToRetailSaleId);
}

#!/usr/bin/env python
import tkinter as tk

class AppName(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.grid()
        self.createWidgets()

    def createWidgets(self):
        self.quitButton = tk.Button(self, text='Quit', command=self.quit)
        self.quitButton.grid()

app = AppName()
app.master.title('Title here ...!')
app.master.iconbitmap('icon.ico')
app.mainloop()

it should work like this !

There is no $contains operator in mongodb.

You can use the answer from JohnnyHK as that works. The closest analogy to contains that mongo has is $in, using this your query would look like:

PersonModel.find({ favouriteFoods: { "$in" : ["sushi"]} }, ...);

It looks like placing the click event directly on the button is causing the problem. For some reason it can't find the function. Not sure why...

If you attach the event handler in the javascript, it does work however.

See it here: http://jsfiddle.net/WfBRr/7/

<button id="display-text" type="button">Display text of all options</button>

document.getElementById('display-text').onclick = function () {
    var x = document.getElementById("mySelect");
    var txt = "All options: ";
    var i;
    for (i = 0; i < x.length; i++) {
        txt = txt + "\n" + x.options[i].value;
    }
    alert(txt);
}

I think you need to set symbreaks = FALSE That should allow for asymmetrical color scales.

I came up with this one, that supports anchor and image tags, and supports single and double quotes.

<[a|img]+\\s+(?:[^>]*?\\s+)?[src|href]+=[\"']([^\"']*)['\"]

So

<a href="/something.ext">click here</a>

Will match:

 Match 1: /something.ext

And

<a href='/something.ext'>click here</a>

Will match:

 Match 1: /something.ext

Same goes for img src attributes

For reasons that aren't clear to me I had declared all of my Methods / Actions as static - apparently if you do this it doesn't work. So just drop the static off

[AllowAnonymous]
[Route()]
public static HttpResponseMessage Get()
{
    return new HttpResponseMessage(System.Net.HttpStatusCode.OK);
}

Became:-

[AllowAnonymous]
[Route()]
public HttpResponseMessage Get()
{
    return new HttpResponseMessage(System.Net.HttpStatusCode.OK);
}

with Kotlin I execute this code:

requireContext().startActivity<YourTargetActivity>()

keywords = [1,2,3,4];
doc.array.pull(1) //this remove one item from a array
doc.array.pull(...keywords) // this remove multiple items in a array

if you want to use ... you should call 'use strict'; at the top of your js file; :)

What you want to do is to make an interface which handles this code and all your classes implement the interface.

class IEventListener{
public:
   void OnEvent(int x) = 0;  // renamed Callback to OnEvent removed the instance, you can add it back if you want.
};


class MyClass :public IEventListener
{
    ...
    void OnEvent(int x); //typically such a function is NOT static. This wont work if it is static.
};

class YourClass :public IEventListener
{

Note that for this to work the "Callback" function is non static which i believe is an improvement. If you want it to be static, you need to do it as JaredC suggests with templates.

You can turn off foreign key checks:

SET FOREIGN_KEY_CHECKS = 0;

/* DO WHAT YOU NEED HERE */

SET FOREIGN_KEY_CHECKS = 1;

Please make sure to NOT use this on production and have a backup.

Warning: Illegal string offset 'XXX'

This happens when you try to access an array element with the square bracket syntax, but you're doing this on a string, and not on an array, so the operation clearly doesn't make sense.

Example:

$var = "test";
echo $var["a_key"];

If you think the variable should be an array, see where it comes from and fix the problem there.

To make the answer provided by @abourget more complete, the value of scopeValue[field] in the following line of code could be undefined. This would result in an error when setting subfield:

<textarea ng-model="scopeValue[field][subfield]"></textarea>

One way of solving this problem is by adding an attribute ng-focus="nullSafe(field)", so your code would look like the below:

<textarea ng-focus="nullSafe(field)" ng-model="scopeValue[field][subfield]"></textarea>

Then you define nullSafe( field ) in a controller like the below:

$scope.nullSafe = function ( field ) {
  if ( !$scope.scopeValue[field] ) {
    $scope.scopeValue[field] = {};
  }
};

This would guarantee that scopeValue[field] is not undefined before setting any value to scopeValue[field][subfield].

Note: You can't use ng-change="nullSafe(field)" to achieve the same result because ng-change happens after the ng-model has been changed, which would throw an error if scopeValue[field] is undefined.

The reason #2 fails is because sys.modules['module'] does not exist (the import routine has its own scope, and cannot see the module local name), and there's no module module or package on-disk. Note that you can separate multiple imported names by commas.

from package.subpackage.module import attribute1, attribute2, attribute3

Also:

from package.subpackage import module
print module.attribute1

You can do it with jQuery UI without another JavaScript library. Just add a function to the .resizable resize event to adjust the width of the other div.

$("#left_pane").resizable({
  handles: 'e', // 'East' side of div draggable
  resize: function() {
    $("#right_pane").outerWidth( $("#container").innerWidth() - $("#left_pane").outerWidth() );
  }
});

Here's the complete JSFiddle.

with the help of @JsonView we can decide fields of model classes to serialize which satisfy the minimal criteria ( we have to define the criteria) like we can have one core class with 10 properties but only 5 properties can be serialize which are needful for client only

Define our Views by simply creating following class:

public class Views
{
    static class Android{};
    static class IOS{};
    static class Web{};
}

Annotated model class with views:

public class Demo 
{
    public Demo() 
    {
    }

@JsonView(Views.IOS.class)
private String iosField;

@JsonView(Views.Android.class)
private String androidField;

@JsonView(Views.Web.class)
private String webField;

 // getters/setters
...
..
}

Now we have to write custom json converter by simply extending HttpMessageConverter class from spring as:

    public class CustomJacksonConverter implements HttpMessageConverter<Object> 
    {
    public CustomJacksonConverter() 
        {
            super();
        //this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView(Views.ClientView.class));
        this.delegate.getObjectMapper().configure(MapperFeature.DEFAULT_VIEW_INCLUSION, true);
        this.delegate.getObjectMapper().setSerializationInclusion(Include.NON_NULL);

    }

    // a real message converter that will respond to methods and do the actual work
    private MappingJackson2HttpMessageConverter delegate = new MappingJackson2HttpMessageConverter();

    @Override
    public boolean canRead(Class<?> clazz, MediaType mediaType) {
        return delegate.canRead(clazz, mediaType);
    }

    @Override
    public boolean canWrite(Class<?> clazz, MediaType mediaType) {
        return delegate.canWrite(clazz, mediaType);
    }

    @Override
    public List<MediaType> getSupportedMediaTypes() {
        return delegate.getSupportedMediaTypes();
    }

    @Override
    public Object read(Class<? extends Object> clazz,
            HttpInputMessage inputMessage) throws IOException,
            HttpMessageNotReadableException {
        return delegate.read(clazz, inputMessage);
    }

    @Override
    public void write(Object obj, MediaType contentType, HttpOutputMessage outputMessage) throws IOException, HttpMessageNotWritableException 
    {
        synchronized(this) 
        {
            String userAgent = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest().getHeader("userAgent");
            if ( userAgent != null ) 
            {
                switch (userAgent) 
                {
                case "IOS" :
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView(Views.IOS.class));
                    break;
                case "Android" :
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView(Views.Android.class));
                    break;
                case "Web" :
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView( Views.Web.class));
                    break;
                default:
                    this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView( null ));
                    break;
                }
            }
            else
            {
                // reset to default view
                this.delegate.getObjectMapper().setConfig(this.delegate.getObjectMapper().getSerializationConfig().withView( null ));
            }
            delegate.write(obj, contentType, outputMessage);
        }
    }

}

Now there is need to tell spring to use this custom json convert by simply putting this in dispatcher-servlet.xml

<mvc:annotation-driven>
        <mvc:message-converters register-defaults="true">
            <bean id="jsonConverter" class="com.mactores.org.CustomJacksonConverter" >
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

That's how you will able to decide which fields to get serialize.

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

This code is the corrected version of iambriansreed's answer:

<script type="text/javascript">
    $(function() {
        $("#bookmarkme").click(function() {
            // Mozilla Firefox Bookmark
            if ('sidebar' in window && 'addPanel' in window.sidebar) { 
                window.sidebar.addPanel(location.href,document.title,"");
            } else if( /*@cc_on!@*/false) { // IE Favorite
                window.external.AddFavorite(location.href,document.title); 
            } else { // webkit - safari/chrome
                alert('Press ' + (navigator.userAgent.toLowerCase().indexOf('mac') != - 1 ? 'Command/Cmd' : 'CTRL') + ' + D to bookmark this page.');
            }
        });
    });
</script>

Here is what I did and I'm happy to say that this worked for me. I too wanted a 2x2, 3x3 etc. grid of items to cover the entire screen. Gridlayouts do not adhere to the width of the screen. LinearLayouts kind of work but you cant use nested weights.

The best option for me was to use Fragments I used this tutorial to get started with what I wanted to do.

Here is some code:

Main Activity:

public class GridHolderActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main_6);
    }
}

activity_main_6 XML (inflates 3 fragments)

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <fragment
        android:id="@+id/frag1"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name=".TwoHorizontalGridFragment"
        tools:layout="@layout/two_horiz" />
    <fragment
        android:id="@+id/frag2"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name=".TwoHorizontalGridFragment"
        tools:layout="@layout/two_horiz" />
    <fragment
        android:id="@+id/frag3"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:name=".Grid.TwoHorizontalGridFragment"
        tools:layout="@layout/two_horiz" />

Base fragment layout

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="wrap_content"
    android:layout_gravity="center"
    android:layout_height="match_parent">

    <ImageQueue
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:id="@+id/img1"
        android:layout_weight="1"/>


    <ImageQueue
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:id="@+id/img2"
        android:layout_weight="1"/>
</LinearLayout>

Fragment Class (only handles initialization of a custom view) inflates 2 tiles per fragment

public class TwoHorizontalGridFragment extends Fragment {
private View rootView;

private ImageQueue imageQueue1;
private ImageQueue imageQueue2;

@Override
public View onCreateView(LayoutInflater inflater,
                         ViewGroup container, Bundle savedInstanceState) {
    /**
     * Inflate the layout for this fragment
     */
    rootView = inflater.inflate(
            R.layout.two_horiz, container, false);
    return rootView;
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    imageQueue1 = (ImageQueue)rootView.findViewById(R.id.img1);
    imageQueue2 = (ImageQueue)rootView.findViewById(R.id.img2);
    imageQueue1.updateFiles();
    imageQueue2.updateFiles();
}

}

Thats it!

This is a weird work around to using nested weights, essentially. It gives me a perfect 2x3 grid that fills the entire screen of both my 10 inch tablet and my HTC droid DNA. Let me know how it goes for you!

You can store favourites with no associated menu in a separate table:

CREATE TABLE FavoriteWithoutMenu
(
  FavoriteWithoutMenuId uuid NOT NULL, --Primary key
  UserId uuid NOT NULL,
  RecipeId uuid NOT NULL,
  UNIQUE KEY (UserId, RecipeId)
)

if(strcmp(aString, bString) == 0){
    //strings are the same
}

godspeed

Here's what I've been doing to cope with the situation.

I use global imports on a new test class.

import static org.junit.Assert.*;
import static org.mockito.Mockito.*;
import static org.mockito.Matchers.*;

When you are finished writing your test and need to commit, you just CTRL+SHIFT+O to organize the packages. For example, you may just be left with:

import static org.mockito.Mockito.doThrow;
import static org.mockito.Mockito.mock;
import static org.mockito.Mockito.verify;
import static org.mockito.Mockito.when;
import static org.mockito.Matchers.anyString;

This allows you to code away without getting 'stuck' trying to find the correct package to import.

UPDATE: I have since created a more effective solution upon which I have elaborated here: https://stackoverflow.com/a/34277491/501113

I find myself working more and more in the Scala Worksheet within the Scala IDE for Eclipse (and I believe there is something equivalent in IntelliJ IDEA). Anyway, I need to be able to do a one-liner to output some of the contents as I get the "Output exceeds cutoff limit." message if I am doing anything significant, especially with the Scala collections.

I came up with a one-liner I insert into the top of each new Scala Worksheet to simplify this (and so I don't have to do the whole external library import exercise for a very simple need). If you are a stickler and notice that it is technically two lines, it's only to make it more readable in this forum. It is a single line in my Scala Worksheet.

def printToFile(content: String, location: String = "C:/Users/jtdoe/Desktop/WorkSheet.txt") =
  Some(new java.io.PrintWriter(location)).foreach{f => try{f.write(content)}finally{f.close}}

And the usage is simply:

printToFile("A fancy test string\ncontaining newlines\nOMG!\n")

This allows me to optionally provide the file name should I want to have additional files beyond the default (which completely overwrites the file each time the method is called).

So, the second usage is simply:

printToFile("A fancy test string\ncontaining newlines\nOMG!\n", "C:/Users/jtdoe/Desktop/WorkSheet.txt")

Enjoy!

If you want to input a description you can use this. This works on IE 9 and all other browsers.

<input type="text" onclick="if(this.value=='CVC2: '){this.value='';}" onblur="if(this.value==''){this.value='CVC2: ';}" value="CVC2: "/>

Yes you will have to escape all double quotes by a backslash.

Well my solution was another one, or let's say, the bug was:

I simply had another imageview with the same id in another <included /> twice-encapsuled xml layout, which was found before the one that i wanted to react on the click. Solution: Give one of them another id...

Given a list:

var list = new List<Child>()
{
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "John"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Bob", Name = "Pete"},
    new Child()
        {School = "School1", FavoriteColor = "blue", Friend = "Bob", Name = "Fred"},
    new Child()
        {School = "School2", FavoriteColor = "blue", Friend = "Fred", Name = "Bob"},
};

The query would look like:

var newList = list
    .GroupBy(x => new {x.School, x.Friend, x.FavoriteColor})
    .Select(y => new ConsolidatedChild()
        {
            FavoriteColor = y.Key.FavoriteColor,
            Friend = y.Key.Friend,
            School = y.Key.School,
            Children = y.ToList()
        }
    );

Test code:

foreach(var item in newList)
{
    Console.WriteLine("School: {0} FavouriteColor: {1} Friend: {2}", item.School,item.FavoriteColor,item.Friend);
    foreach(var child in item.Children)
    {
        Console.WriteLine("\t Name: {0}", child.Name);
    }
}

Result:

School: School1 FavouriteColor: blue Friend: Bob
    Name: John
    Name: Fred
School: School2 FavouriteColor: blue Friend: Bob
    Name: Pete
School: School2 FavouriteColor: blue Friend: Fred
    Name: Bob

None of them are "better" than the others. The third is, to me, more readable, but to someone who doesn't use foreaches it might look odd (they might prefer the first). All 3 are pretty clear to anyone who understands Java, so pick whichever makes you feel better about the code.

The first one is the most basic, so it's the most universal pattern (works for arrays, all iterables that I can think of). That's the only difference I can think of. In more complicated cases (e.g. you need to have access to the current index, or you need to filter the list), the first and second cases might make more sense, respectively. For the simple case (iterable object, no special requirements), the third seems the cleanest.

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

In interface Builder. Select the UIButton -> Attributes Inspector -> Edge=Title and modify the edge insets

Use WebRequest. From Scott Hanselman:

public static string HttpPost(string URI, string Parameters) 
{
   System.Net.WebRequest req = System.Net.WebRequest.Create(URI);
   req.Proxy = new System.Net.WebProxy(ProxyString, true);
   //Add these, as we're doing a POST
   req.ContentType = "application/x-www-form-urlencoded";
   req.Method = "POST";
   //We need to count how many bytes we're sending. 
   //Post'ed Faked Forms should be name=value&
   byte [] bytes = System.Text.Encoding.ASCII.GetBytes(Parameters);
   req.ContentLength = bytes.Length;
   System.IO.Stream os = req.GetRequestStream ();

Jackson has an XmlMapper which will support this out of the box, no need to write any code at all.

Here's a nice tutorial https://www.baeldung.com/jackson-xml-serialization-and-deserialization

Maven dependency:

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
    <version>2.9.8</version>
</dependency>

For writing a Map to xml:

Map<String, String> map = new HashMap<>();
map.put("SomeKey", "someValue");

XmlMapper mapper = new XmlMapper();
String xml = mapper.writeValueAsString(map);

Will give you

<HashMap><SomeKey>someValue</SomeKey></HashMap>

I was able to customise the root element by creating a HashMap subclass

@JacksonXmlRootElement(localName = "MyRootElement")
public class XmlHashMap<K, V> extends HashMap<K, V>
{

}

So now

Map<String, String> map = new XmlHashMap<>();
map.put("SomeKey", "someValue");

XmlMapper mapper = new XmlMapper();
String xml = mapper.writeValueAsString(map);

Will give you

<MyRootElement><SomeKey>someValue</SomeKey></MyRootElement>

I would like to add a word of warning when you are dealing with C++11-style allocator-aware containers. Swapping and assignment have subtly different semantics.

For concreteness, let us consider a container std::vector<T, A>, where A is some stateful allocator type, and we'll compare the following functions:

void fs(std::vector<T, A> & a, std::vector<T, A> & b)
{ 
    a.swap(b);
    b.clear(); // not important what you do with b
}

void fm(std::vector<T, A> & a, std::vector<T, A> & b)
{
    a = std::move(b);
}

The purpose of both functions fs and fm is to give a the state that b had initially. However, there is a hidden question: What happens if a.get_allocator() != b.get_allocator()? The answer is: It depends. Let's write AT = std::allocator_traits<A>.

• If AT::propagate_on_container_move_assignment is std::true_type, then fm reassigns the allocator of a with the value of b.get_allocator(), otherwise it does not, and a continues to use its original allocator. In that case, the data elements need to be swapped individually, since the storage of a and b is not compatible.

• If AT::propagate_on_container_swap is std::true_type, then fs swaps both data and allocators in the expected fashion.

• If AT::propagate_on_container_swap is std::false_type, then we need a dynamic check.

  • If a.get_allocator() == b.get_allocator(), then the two containers use compatible storage, and swapping proceeds in the usual fashion.
  • However, if a.get_allocator() != b.get_allocator(), the program has undefined behaviour (cf. [container.requirements.general/8].

The upshot is that swapping has become a non-trivial operation in C++11 as soon as your container starts supporting stateful allocators. That's a somewhat "advanced use case", but it's not entirely unlikely, since move optimizations usually only become interesting once your class manages a resource, and memory is one of the most popular resources.

UPDATE (Jan 2020): There are many great online places to get beginner practice at Python, some which are highly engaging and/or otherwise interactive. These sites are generally more practical than the Python Challenge (http://pythonchallenge.com), which you can tackle later. (After years of experience, you can try the Python "wat" quiz). For now, it's most important to learn, practice, and have fun. Welcome to Python!

• http://codecombat.com (gamified learning, nice graphics)
• http://codecademy.com/catalog/language/python (choice of topics)
• http://codingbat.com/python (very lightweight, older; good for slow internet)
• http://pythontutor.com (intermediate; learn how Python works internally)
• http://learnpython.org (lightweight but modern)
• http://pyschools.com (Udemy; also lightweight but modern)

ps. BTW (by the way), your experience puts you right in the heart of the target audience of my Python book, Core Python Programming. That audience is those who know how to code in another high-level language but want to learn Python as quickly but as in-depth as possible. Reviews, philosophy, and other info at http://corepython.com

I'm thinking no. Bookmarks/favorites should be under the control of the user, imagine if any site you visited could insert itself into your bookmarks with just some javascript.

I think, from my own experience on problems with more advanced data structures, that the most important thing you can do here, is to get a good knowledge on the general concept of tress as data structures. If you understand the basic mechanism behind the concept it will be quite easy to implement the solution that fits your problem. There are a lot of good sources out there describing the concept. What "saved" me years ago on this particular problem was section 2.3 in "The Art of Computer Programming".

Using with Moment.js and Comparison Query Operators

  var today = moment().startOf('day');
  // "2018-12-05T00:00:00.00
  var tomorrow = moment(today).endOf('day');
  // ("2018-12-05T23:59:59.999

  Example.find(
  {
    // find in today
    created: { '$gte': today, '$lte': tomorrow }
    // Or greater than 5 days
    // created: { $lt: moment().add(-5, 'days') },
  }), function (err, docs) { ... });

Here's 2 sorts I came up with my roommate in college

1) Check the order 2) Maybe a miracle happened, go to 1

and

1) check if it is in order, if not 2) put each element into a packet and bounce it off a distant server back to yourself. Some of those packets will return in a different order, so go to 1

IoC/DI is a design concept, but unfortunately it's often taken as a concept that applies to certain languages (or typing systems). I'd love to see dependency injection containers become far more popular in Python. There's Spring, but that's a super-framework and seems to be a direct port of the Java concepts without much consideration for "The Python Way."

Given Annotations in Python 3, I decided to have a crack at a full featured, but simple, dependency injection container: https://github.com/zsims/dic . It's based on some concepts from a .NET dependency injection container (which IMO is fantastic if you're ever playing in that space), but mutated with Python concepts.

Take a look at Shell MegaPack control set. It provides Windows Explorer like folder/file browsing with most of the features and functionality like context menus, renaming, drag-drop, icons, overlay icons, thumbnails, etc

validator package:

There seems to be a nice package by Yonatan Matalon called UrlUtil. Quoting its API:

isValidWebPageAddress(java.lang.String address, boolean validateSyntax, 
                      boolean validateExistance) 
Checks if the given address is a valid web page address.

Sun's approach - check the network address

Sun's Java site offers connect attempt as a solution for validating URLs.

Other regex code snippets:

There are regex validation attempts at Oracle's site and weberdev.com.

here's one way you can do it with awk

curl -sL 'http://twitter.com/users/username.json' | awk -F"," -v k="text" '{
    gsub(/{|}/,"")
    for(i=1;i<=NF;i++){
        if ( $i ~ k ){
            print $i
        }
    }
}'

For SQL Server 2012 and above: If you place the query into a string then you can get the result set data types like so:

DECLARE @query nvarchar(max) = 'select 12.1 / 10.1 AS [Column1]';
EXEC sp_describe_first_result_set @query, null, 0;  

XmlSerializer xs = new XmlSerializer(typeof(User), new XmlRootAttribute("yourRootName")); 

My blog has a complete series of tutorial starting from scratch for WPF MVVM and WPF Prism. Have a look here: http://blog.raffaeu.com/archive/2009/06/03/wpf-and-vmmv-tutorial-01-introduction.aspx

Some social tools like Google+ use a simple method to get a favicon for external links, fetching http://your.domainname.com/favicon.ico

Since they don't prefetch the HTML content, the <link> tag will not work. In this case, you might want to use a mod_rewrite rule or just place the file in the default location.

Strings have helper functions and manage char arrays automatically. You can concatenate strings, for a char array you would need to copy it to a new array, strings can change their length at runtime. A char array is harder to manage than a string and certain functions may only accept a string as input, requiring you to convert the array to a string. It's better to use strings, they were made so that you don't have to use arrays. If arrays were objectively better we wouldn't have strings.

The only way to add any book marks in MobileSafari (including ones on the home screen) is with the builtin UI, and that Apples does not provide anyway to do this from scripts within a page. In fact, I am pretty sure there is no mechanism for doing this on the desktop version of Safari either.

If PowerShell is available to you...

Get-Service -DisplayName *Network* | ForEach-Object{Write-Host $_.Status : $_.Name}

Will give you...

Stopped : napagent
Stopped : NetDDE
Stopped : NetDDEdsdm
Running : Netman
Running : Nla
Stopped : WMPNetworkSvc
Stopped : xmlprov

You can replace the ****Network**** with a specific service name if you just need to check one service.

Remove javascript: from onclick=".., onsubmit=".. declarations

javascript: prefix is used only in href="" or similar attributes (not events related)

Not specific to C, but I've always liked the XOR operator. One cool thing it can do is "swap without a temp value":

int a = 1;
int b = 2;

printf("a = %d, b = %d\n", a, b);

a ^= b;
b ^= a;
a ^= b;

printf("a = %d, b = %d\n", a, b);

Result:

a = 1, b = 2

a = 2, b = 1

Try the commons collections API:

List<Cat> bigList = ....; // master list

Collection<Cat> smallList = CollectionUtils.select(bigList, new Predicate() {
    public boolean evaluate(Object o) {
        Cat c = (Cat)o;
        return c.getFavoriteFood().equals("Wiskas") 
            && c.getWhateverElse().equals(Something);
    }
});

Of course you don't have to use an anonymous class every time, you could create implementations of the Predicate interface for commonly used searchs.

Ctrl+] - go to definition
Ctrl+T - Jump back from the definition.
Ctrl+W Ctrl+] - Open the definition in a horizontal split

Add these lines in vimrc
map <C-\> :tab split<CR>:exec("tag ".expand("<cword>"))<CR>
map <A-]> :vsp <CR>:exec("tag ".expand("<cword>"))<CR>

Ctrl+\ - Open the definition in a new tab
Alt+] - Open the definition in a vertical split

After the tags are generated. You can use the following keys to tag into and tag out of functions:

Ctrl+Left MouseClick - Go to definition
Ctrl+Right MouseClick - Jump back from definition

The \x.. sequence is something that's specific to Python. It's not a universal byte escape sequence.

How you actually enter in UTF-8-encoded non-ASCII depends on your OS and/or your editor. Here's how you do it in Windows. For OS X to enter a with an acute accent you can just hit option + E, then A, and almost all text editors in OS X support UTF-8.

Eclipse Link, for many reasons, but notably I feel like it has less bloat than other main stream solutions (at least less in-your-face bloat).

Oh and Eclipse Link has been chosen to be the reference implementation for JPA 2.0

A free and open source password manager that keeps all of your passwords safe in one place is "KeePass" and alternative to Windows Credential Manager.

If you haven't read a man page, you're not a real programmer.

I prefer:

def g(x):
  y0 = x + 1
  y1 = x * 3
  y2 = y0 ** y3
  return {'y0':y0, 'y1':y1 ,'y2':y2 }

It seems everything else is just extra code to do the same thing.

While working with MVC and having lots of if statements where i only care about either true or false, and printing null, or string.Empty in the other case, I came up with:

public static TResult WhenTrue<TResult>(this Boolean value, Func<TResult> expression)
{
    return value ? expression() : default(TResult);
}

public static TResult WhenTrue<TResult>(this Boolean value, TResult content)
{
    return value ? content : default(TResult);
}

public static TResult WhenFalse<TResult>(this Boolean value, Func<TResult> expression)
{
    return !value ? expression() : default(TResult);
}

public static TResult WhenFalse<TResult>(this Boolean value, TResult content)
{
    return !value ? content : default(TResult);
}

It allows me to change <%= (someBool) ? "print y" : string.Empty %> into <%= someBool.WhenTrue("print y") %> .

I only use it in my Views where I mix code and HTML, in code files writing the "longer" version is more clear IMHO.

You may want to look at IBExpert Personal Edition. While not open source, this is a very good tool for designing, building, and administering Firebird and InterBase databases.

The Personal Edition is free, but some of the more advanced features are not available. Still, even without the slick extras, the free version is very powerful.

Another option is to split off the textarea in the Site.css as follows:

/* Set width on the form input elements since they're 100% wide by default */

input,
select {

  max-width: 280px;
}

textarea {

  /*max-width: 280px;*/
  max-width: 500px;
  width: 280px;
  height: 200px;
}

also (in my MVC 5) add ref to textarea:

@Html.TextAreaFor(model => ................... @class = "form-control", @id="textarea"............

It worked for me

This code calculates the gcd of more than two numbers depending on the choice given by # the user, here user gives the number

  numbers.append(number)
numbers_sorted = sorted(numbers)
print  'NUMBERS SORTED IN INCREASING ORDER\n',numbers_sorted
gcd = numbers_sorted[0]

for i in range(1, count):
  divisor = gcd
  dividend = numbers_sorted[i]
  remainder = dividend % divisor
  if remainder == 0 :
  gcd = divisor
  else :
    while not remainder == 0 :
      dividend_one = divisor
      divisor_one = remainder
      remainder = dividend_one % divisor_one
      gcd = divisor_one

print 'GCD OF ' ,count,'NUMBERS IS \n', gcd

• The first danger lies in reload(sys).

  When you reload a module, you actually get two copies of the module in your runtime. The old module is a Python object like everything else, and stays alive as long as there are references to it. So, half of the objects will be pointing to the old module, and half to the new one. When you make some change, you will never see it coming when some random object doesn't see the change:

  (This is IPython shell)
  
  In [1]: import sys
  
  In [2]: sys.stdout
  Out[2]: <colorama.ansitowin32.StreamWrapper at 0x3a2aac8>
  
  In [3]: reload(sys)
  <module 'sys' (built-in)>
  
  In [4]: sys.stdout
  Out[4]: <open file '<stdout>', mode 'w' at 0x00000000022E20C0>
  
  In [11]: import IPython.terminal
  
  In [14]: IPython.terminal.interactiveshell.sys.stdout
  Out[14]: <colorama.ansitowin32.StreamWrapper at 0x3a9aac8>
  

• Now, sys.setdefaultencoding() proper

  All that it affects is implicit conversion str<->unicode. Now, utf-8 is the sanest encoding on the planet (backward-compatible with ASCII and all), the conversion now "just works", what could possibly go wrong?

  Well, anything. And that is the danger.

  • There may be some code that relies on the UnicodeError being thrown for non-ASCII input, or does the transcoding with an error handler, which now produces an unexpected result. And since all code is tested with the default setting, you're strictly on "unsupported" territory here, and no-one gives you guarantees about how their code will behave.
  • The transcoding may produce unexpected or unusable results if not everything on the system uses UTF-8 because Python 2 actually has multiple independent "default string encodings". (Remember, a program must work for the customer, on the customer's equipment.)
    • Again, the worst thing is you will never know that because the conversion is implicit -- you don't really know when and where it happens. (Python Zen, koan 2 ahoy!) You will never know why (and if) your code works on one system and breaks on another. (Or better yet, works in IDE and breaks in console.)

The accepted answer doesn't take into account hard or soft links, and would count those files twice. You'd want to keep track of which inodes you've seen, and not add the size for those files.

import os
def get_size(start_path='.'):
    total_size = 0
    seen = {}
    for dirpath, dirnames, filenames in os.walk(start_path):
        for f in filenames:
            fp = os.path.join(dirpath, f)
            try:
                stat = os.stat(fp)
            except OSError:
                continue

            try:
                seen[stat.st_ino]
            except KeyError:
                seen[stat.st_ino] = True
            else:
                continue

            total_size += stat.st_size

    return total_size

RemoteEndPoint is a property, its type is System.Net.EndPoint which inherits from System.Net.IPEndPoint.

If you take a look at IPEndPoint's members, you'll see that there's an Address property.

Python has two kinds of sorts: a sort method (or "member function") and a sort function. The sort method operates on the contents of the object named -- think of it as an action that the object is taking to re-order itself. The sort function is an operation over the data represented by an object and returns a new object with the same contents in a sorted order.

Given a list of integers named l the list itself will be reordered if we call l.sort():

>>> l = [1, 5, 2341, 467, 213, 123]
>>> l.sort()
>>> l
[1, 5, 123, 213, 467, 2341]

This method has no return value. But what if we try to assign the result of l.sort()?

>>> l = [1, 5, 2341, 467, 213, 123]
>>> r = l.sort()
>>> print(r)
None

r now equals actually nothing. This is one of those weird, somewhat annoying details that a programmer is likely to forget about after a period of absence from Python (which is why I am writing this, so I don't forget again).

The function sorted(), on the other hand, will not do anything to the contents of l, but will return a new, sorted list with the same contents as l:

>>> l = [1, 5, 2341, 467, 213, 123]
>>> r = sorted(l)
>>> l
[1, 5, 2341, 467, 213, 123]
>>> r
[1, 5, 123, 213, 467, 2341]

Be aware that the returned value is not a deep copy, so be cautious about side-effecty operations over elements contained within the list as usual:

>>> spam = [8, 2, 4, 7]
>>> eggs = [3, 1, 4, 5]
>>> l = [spam, eggs]
>>> r = sorted(l)
>>> l
[[8, 2, 4, 7], [3, 1, 4, 5]]
>>> r
[[3, 1, 4, 5], [8, 2, 4, 7]]
>>> spam.sort()
>>> eggs.sort()
>>> l
[[2, 4, 7, 8], [1, 3, 4, 5]]
>>> r
[[1, 3, 4, 5], [2, 4, 7, 8]]

This might solve your problem.

after doing changes you can commit it and then

git remote add origin https://(address of your repo) it can be https or ssh
then
git push -u origin master

hope it works for you.

thanks

if you use recompose, use mapProps to make new props derived from incoming props

Edit for example:

import { compose, mapProps } from 'recompose';

const SomeComponent = ({ url, onComplete }) => (
  {url ? (
    <View />
  ) : null}
)

export default compose(
  mapProps(({ url, storeUrl, history, ...props }) => ({
    ...props,
    onClose: () => {
      history.goBack();
    },
    url: url || storeUrl,
  })),
)(SomeComponent);

There are 8 bits in a byte (normally speaking in Windows).

However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.

In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.

EDITED

Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.

Here is a simple code snippet:

function getIndexOfSubStr(str, searchToken, preIndex, output) {
    var result = str.match(searchToken);
    if (result) {
        output.push(result.index +preIndex);
        str=str.substring(result.index+searchToken.length);
        getIndexOfSubStr(str, searchToken, preIndex, output)
    }
    return output;
}

var str = "my name is 'xyz' and my school name is 'xyz' and my area name is 'xyz' ";
var searchToken ="my";
var preIndex = 0;

console.log(getIndexOfSubStr(str, searchToken, preIndex, []));

The fix is really simple: just replace YOUR_API_KEY on the last line of your code with your actual API key!

If you don't have one, you can get it for free on the Google Developers Website.

OK, so looking at Comparison of file systems if you only care about the main players file systems:

• Windows (FAT32, NTFS): Any Unicode except NUL, \, /, :, *, ", <, >, |. Also, no space character at the start or end, and no period at the end.
• Mac(HFS, HFS+): Any valid Unicode except : or /
• Linux(ext[2-4]): Any byte except NUL or /

so any byte except NUL, \, /, :, *, ", <, >, | and you can't have files/folders call . or .. and no control characters (of course).

In website panels like cPanel you may add a single % (percentage sign) in allowed hostnames to access your MySQL database.

By adding a single % you can access your database from any IP or website even from desktop applications.

Here are two functions to calculate distance and bearing, which are based on the code in previous messages and https://gist.github.com/jeromer/2005586 (added tuple type for geographical points in lat, lon format for both functions for clarity). I tested both functions and they seem to work right.

#coding:UTF-8
from math import radians, cos, sin, asin, sqrt, atan2, degrees

def haversine(pointA, pointB):

    if (type(pointA) != tuple) or (type(pointB) != tuple):
        raise TypeError("Only tuples are supported as arguments")

    lat1 = pointA[0]
    lon1 = pointA[1]

    lat2 = pointB[0]

When a user tries to connect to your Web site, IIS assigns the connection to the IUSER_ComputerName account, where ComputerName is the name of the server on which IIS is running. By default, the IUSER_ComputerName account is a member of the Guests group. This group has security restrictions. Try to grand access to IUSER_ComputerName to that folder

Here is very good described answer about IIS security

Hope this helps

You cannot instantiate an interface - you must provide a concrete implementation of IEnumerable.

Here is my answer,

In row.model.ts

export interface Row {
   otherProperty : type;
   checked : bool;
   otherProperty : type;
   ...
}

In .html

<tr class="even" *ngFor="let item of rows">
   <input [checked]="item.checked" type="checkbox">
</tr>

In .ts

rows : Row[] = [];

update the rows in component.ts

You can find if the textbox is disabled using is method by passing :disabled selector to it. Try this.

if($('textbox').is(':disabled')){
     //textbox is disabled
}

ad 1. It does not implement its methods.

ad 4. The purpose of one interface extending, not implementing another, is to build a more specific interface. For example, SortedMap is an interface that extends Map. A client not interested in the sorting aspect can code against Map and handle all the instances of for example TreeMap, which implements SortedMap. At the same time, another client interested in the sorted aspect can use those same instances through the SortedMap interface.

In your example you are repeating the methods from the superinterface. While legal, it's unnecessary and doesn't change anything in the end result. The compiled code will be exactly the same whether these methods are there or not. Whatever Eclipse's hover says is irrelevant to the basic truth that an interface does not implement anything.

Many people advise using col- and col-offset- classes, but it doesn't work right for me, it centers the form only for a certain screen size, but if you change it, the markup slides out.

I found two ways to align form:

Use a custom CSS:

<div class=".center">
  <form>

  </form>
</div>

.center {
  margin: 0 auto;
  width: 100%;
}
form {
  margin: 0 auto;
  width: 500px; /*find your value*/
  text-align: center;
}

Original code

OR just copy a CSS class "justify-content-center" from bootstrap 4, it's very short:

.justify-content-center {
    -ms-flex-pack: center !important;
    justify-content: center !important;
}

And then use it:

<div class="container">
    <div class="row">
        <div class="form-inline justify-content-center">
        </div>
    </div>
</div>

Im doing this in coffeescript

booking_module_time_clock_convert_id = () ->
  if $('.booking_module_time_clock').length
    idnumber = 1
    for a in $('.booking_module_time_clock')
      elementID = $(a).attr("id")
      $(a).attr( 'id', "#{elementID}_#{idnumber}" )
      idnumber++

Here is an article that explains it all, with their performance difference and usage over JOINS.

SQL Server CROSS APPLY and OUTER APPLY over JOINS

As suggested in this article, there is no performance difference between them for normal join operations (INNER AND CROSS).

The usage difference arrives when you have to do a query like this:

CREATE FUNCTION dbo.fn_GetAllEmployeeOfADepartment(@DeptID AS INT)  
RETURNS TABLE 
AS 
RETURN 
   ( 
   SELECT * FROM Employee E 
   WHERE E.DepartmentID = @DeptID 
   ) 
GO 
SELECT * FROM Department D 
CROSS APPLY dbo.fn_GetAllEmployeeOfADepartment(D.DepartmentID)

That is, when you have to relate with function. This cannot be done using INNER JOIN, which would give you the error "The multi-part identifier "D.DepartmentID" could not be bound." Here the value is passed to the function as each row is read. Sounds cool to me. :)

Install brew or apt-get is also not easy for me so I downloaded mysql via: https://dev.mysql.com/downloads/connector/python/, installed it. So I can find mysql_config int this directory: /usr/local/mysql/bin

the next step is:

1. export PATH=$PATH:/usr/local/mysql/bin
2. pip install MySQL-python==1.2.5

public class checkBoxSel {

    public static void main(String[] args) {

         WebDriver driver = new FirefoxDriver();
         EventFiringWebDriver dr = null ;


         dr = new EventFiringWebDriver(driver);
         dr.get("http://www.google.co.in/");

         dr.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

         dr.findElement(By.linkText("Gmail")).click() ;

         Select sel = new Select(driver.findElement(By.tagName("select")));
         sel.selectByValue("fil");

    }

}

I am using GOOGLE LOGIN PAGE to test the seletion option. The above example was to find and select language "Filipino" from the drop down list. I am sure this will solve the problem.

I'd like to add my own efforts to this list. You can find out more information here:

brzy framework

It's in early development and I'm still working on it aggressively. It includes features like:

• A focus on simplicity and extensibility.
• Integrated build tool.
• Modular design; some initial modules includes support for scalate, email, jms, jpa, squeryl, cassandra, cron services and more.
• Simple RESTful controllers and actions.

Any and all feedback is much appreciated.

UPDATE: 2011-09-078, I just posted a major update to version 0.9.1. There's more info at http://brzy.org which includes a screencast.

way mentioned by @dirkgently ( v.begin() + index ) nice and fast for vectors

but std::advance( v.begin(), index ) most generic way and for random access iterators works constant time too.

EDIT
differences in usage:

std::vector<>::iterator it = ( v.begin() + index );

or

std::vector<>::iterator it = v.begin();
std::advance( it, index );

added after @litb notes.

The json.load() method (without "s" in "load") can read a file directly:

import json
with open('strings.json') as f:
    d = json.load(f)
    print(d)

json.loads() method, which is used for string arguments only.

import json

person = '{"name": "Bob", "languages": ["English", "Fench"]}'
print(type(person))
# Output : <type 'str'>

person_dict = json.loads(person)
print( person_dict)
# Output: {'name': 'Bob', 'languages': ['English', 'Fench']}

print(type(person_dict))
# Output : <type 'dict'>

Here , we can see after using loads() takes a string ( type(str) ) as a input and return dictionary.

Pipe to sed -e 's/[\r\n]//g' to remove both Carriage Returns (\r) and Line Feeds (\n) from each text line.

You're right using div.container-fluid and you also need a div.row child. Then, the content must be placed inside without any grid columns. If you have a look at the docs you can find this text:

• Rows must be placed within a .container (fixed-width) or .container-fluid (full-width) for proper alignment and padding.
• Use rows to create horizontal groups of columns.

Not using grid columns it's ok as stated here:

• Content should be placed within columns, and only columns may be immediate children of rows.

And looking at this example, you can read this text:

Full width, single column: No grid classes are necessary for full-width elements.

Here's a live example showing some elements using the correct layout. This way you don't need any custom CSS or hack.

I modified the above function to account for carriage returns in IE. It's untested but I did something similar with it in my code so it should be workable.

function getCaret(el) {
  if (el.selectionStart) { 
    return el.selectionStart; 
  } else if (document.selection) { 
    el.focus(); 

    var r = document.selection.createRange(); 
    if (r == null) { 
      return 0; 
    } 

    var re = el.createTextRange(), 
    rc = re.duplicate(); 
    re.moveToBookmark(r.getBookmark()); 
    rc.setEndPoint('EndToStart', re); 

    var add_newlines = 0;
    for (var i=0; i<rc.text.length; i++) {
      if (rc.text.substr(i, 2) == '\r\n') {
        add_newlines += 2;
        i++;
      }
    }

    //return rc.text.length + add_newlines;

    //We need to substract the no. of lines
    return rc.text.length - add_newlines; 
  }  
  return 0; 
}

Something to be aware of, the $_SESSION variables are still set in the same page after calling session_destroy() where as this is not the case when using unset($_SESSION) or $_SESSION = array(). Also, unset($_SESSION) blows away the $_SESSION superglobal so only do this when you're destroying a session.

With all that said, it's best to do like the PHP docs has it in the first example for session_destroy().

The following code will help you

mvv_count_df.select('mvv').rdd.map(lambda row : row[0]).collect()

there are two cause of this exception:

1

Arrays.asList(factors) returns a List<int[]> where factors is an int array

2

you forgot to add the type parameter to:

ArrayList<Integer> f = new ArrayList(Arrays.asList(factors));

with:

ArrayList<Integer> f = new ArrayList<Integer>(Arrays.asList(factors));  

resulting in a compile-time error:

found   : java.util.List<int[]>
required: java.util.List<java.lang.Integer>

Please check out my gist where I have made a category for UILabel for something very similar, my category lets a UILabel stretch it's height to show all the content: https://gist.github.com/1005520

Or check out this post: https://stackoverflow.com/a/7242981/662605

This would stretch the height, but you can change it around easily to work the other way and stretch the width with something like this, which is I believe what you want to do:

@implementation UILabel (dynamicSizeMeWidth)

- (void)resizeToStretch{
    float width = [self expectedWidth];
    CGRect newFrame = [self frame];
    newFrame.size.width = width;
    [self setFrame:newFrame];
}

- (float)expectedWidth{
    [self setNumberOfLines:1];

    CGSize maximumLabelSize = CGSizeMake(CGRectGetWidth(self.bounds), CGFLOAT_MAX);

    CGSize expectedLabelSize = [[self text] sizeWithFont:[self font] 
                                            constrainedToSize:maximumLabelSize
                                            lineBreakMode:[self lineBreakMode]]; 
    return expectedLabelSize.width;
}

@end

You could more simply use the sizeToFit method available from the UIView class, but set the number of lines to 1 to be safe.

iOS 6 update

If you are using AutoLayout, then you have a built in solution. By setting the number of lines to 0, the framework will resize your label appropriately (adding more height) to fit your text.

iOS 8 update

sizeWithFont: is deprecated so use sizeWithAttributes: instead:

- (float)expectedWidth{
    [self setNumberOfLines:1];

    CGSize expectedLabelSize = [[self text] sizeWithAttributes:@{NSFontAttributeName:self.font}];

    return expectedLabelSize.width;
}

$('div.target').each(function() {
   /* Measure the width of each image. */
   var test = $(this).find('.scrolling img').width();

   /* Find out how many images there are. */
   var testimg = $(this).find('.scrolling img').length;

   /* Do the maths. */
   var final = (test* testimg)*1.2;

   /* Apply the maths to the CSS. */
   $(this).find('scrolling').width(final); 
});

Here you loop through all your div's with class target and you do the calculations. Within this loop you can simply use $(this) to indicate the currently selected <div> tag.

To plot just a selection of your columns you can select the columns of interest by passing a list to the subscript operator:

ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)

What you tried was df['V1','V2'] this will raise a KeyError as correctly no column exists with that label, although it looks funny at first you have to consider that your are passing a list hence the double square brackets [[]].

import matplotlib.pyplot as plt
ax = df[['V1','V2']].plot(kind='bar', title ="V comp", figsize=(15, 10), legend=True, fontsize=12)
ax.set_xlabel("Hour", fontsize=12)
ax.set_ylabel("V", fontsize=12)
plt.show()

I'd suggest looking at the source to something like lighthttpd.

&& ; || are logical operators.... short circuit

& ; | are boolean logical operators.... Non-short circuit

Moving to differences in execution on expressions. Bitwise operators evaluate both sides irrespective of the result of left hand side. But in the case of evaluating expressions with logical operators, the evaluation of the right hand expression is dependent on the left hand condition.

For Example:

int i = 25;
int j = 25;
if(i++ < 0 && j++ > 0)
    System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);

This will print i=26 ; j=25, As the first condition is false the right hand condition is bypassed as the result is false anyways irrespective of the right hand side condition.(short circuit)

int i = 25;
int j = 25;
if(i++ < 0 & j++ > 0)
    System.out.println("OK");
System.out.printf("i = %d ; j = %d",i,j);

But, this will print i=26; j=26,

One of the possible way to do it:

import urllib
...

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    # Python 3
    from urllib.request import urlopen

Long answer to short, if you install boost in custom path, all header files must in ${path}/boost/.

if you want to konw why cmake can't find the requested Boost libraries after you have set BOOST_ROOT/BOOST_INCLUDEDIR, you can check cmake install location path_to_cmake/share/cmake-xxx/Modules/FindBoost.

cmake which will find Boost_INCLUDE_DIR in boost/config.hpp in BOOST_ROOT. That means your boost header file must in ${path}/boost/, any other format (such as ${path}/boost-x.y.z) will not be suitable for find_package in CMakeLists.txt.

Simplest answer to the question:

rand(0..n)

This other solution for covert datetime to unixtimestampmillis.

private static readonly DateTime UnixEpoch = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);

    public static long GetCurrentUnixTimestampMillis()
    {
        DateTime localDateTime, univDateTime;
        localDateTime = DateTime.Now;          
        univDateTime = localDateTime.ToUniversalTime();
        return (long)(univDateTime - UnixEpoch).TotalMilliseconds;
    } 

|= reads the same way as +=.

notification.defaults |= Notification.DEFAULT_SOUND;

is the same as

notification.defaults = notification.defaults | Notification.DEFAULT_SOUND;

where | is the bit-wise OR operator.

All operators are referenced here.

A bit-wise operator is used because, as is frequent, those constants enable an int to carry flags.

If you look at those constants, you'll see that they're in powers of two :

public static final int DEFAULT_SOUND = 1;
public static final int DEFAULT_VIBRATE = 2; // is the same than 1<<1 or 10 in binary
public static final int DEFAULT_LIGHTS = 4; // is the same than 1<<2 or 100 in binary

So you can use bit-wise OR to add flags

int myFlags = DEFAULT_SOUND | DEFAULT_VIBRATE; // same as 001 | 010, producing 011

so

myFlags |= DEFAULT_LIGHTS;

simply means we add a flag.

And symmetrically, we test a flag is set using & :

boolean hasVibrate = (DEFAULT_VIBRATE & myFlags) != 0;

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

Benchmark.

I'd start ramping up the number of threads for an application, starting at 1, and then go to something like 100, run three-five trials for each number of threads, and build yourself a graph of operation speed vs. number of threads.

You should that the four thread case is optimal, with slight rises in runtime after that, but maybe not. It may be that your application is bandwidth limited, ie, the dataset you're loading into memory is huge, you're getting lots of cache misses, etc, such that 2 threads are optimal.

You can't know until you test.

(It's not action="get" or action="post" it's method="get" or method="post"

Try to do it using post method:

<form action="third.php" method="POST">
    Red<input type="checkbox" name="color[]" id="color" value="red">
    Green<input type="checkbox" name="color[]" id="color" value="green">
    Blue<input type="checkbox" name="color[]" id="color" value="blue">
    Cyan<input type="checkbox" name="color[]" id="color" value="cyan">
    Magenta<input type="checkbox" name="color[]" id="color" value="Magenta">
    Yellow<input type="checkbox" name="color[]" id="color" value="yellow">
    Black<input type="checkbox" name="color[]" id="color" value="black">
    <input type="submit" value="submit">
</form>

and in third.php

or for a pericular field you colud get value in:

$_POST['color'][0] //for RED
$_POST['color'][1] // for GREEN

If you need apache Listen port other than 80, you should add next file under ubuntu

"/etc/apache2/ports.conf"

the list of Listen ports

Listen 80
Listen 81
Listen 82

After you have to go on your Virtual hosts conf file and define next

<VirtualHost *:80>
  #...v host 1
</VirtualHost>


<VirtualHost *:81>
  #...host 2
</VirtualHost>


<VirtualHost *:82>
  #...host 3

The code that has to be executed for both alternatives is so similar that you can’t predict a result reliably. The underlying object structure might differ but that’s no challenge to the hotspot optimizer. So it depends on other surrounding conditions which will yield to a faster execution, if there is any difference.

Combining two filter instances creates more objects and hence more delegating code but this can change if you use method references rather than lambda expressions, e.g. replace filter(x -> x.isCool()) by filter(ItemType::isCool). That way you have eliminated the synthetic delegating method created for your lambda expression. So combining two filters using two method references might create the same or lesser delegation code than a single filter invocation using a lambda expression with &&.

But, as said, this kind of overhead will be eliminated by the HotSpot optimizer and is negligible.

In theory, two filters could be easier parallelized than a single filter but that’s only relevant for rather computational intense tasks¹.

So there is no simple answer.

The bottom line is, don’t think about such performance differences below the odor detection threshold. Use what is more readable.

¹…and would require an implementation doing parallel processing of subsequent stages, a road currently not taken by the standard Stream implementation

This method will create the folder if it does not exist and do nothing if it exists:

Directory.CreateDirectory(path);

You don't need to use textarea#message

var message = $('textarea#message').val();

You can directly use

var message = $('#message').val();

position: fixed;

Will make this happen.

It handles like position:absolute; with the exception that it will scroll with the window as the user scrolls down the content.

After calling an request, set timeout to initialize slick slider.

var options = {
    arrows: false,
    slidesToShow: 1,
    variableWidth: true,
    centerPadding: '10px'
}

$.ajax({
    type: "GET",
    url: review_url+"?page="+page,
    success: function(result){
        setTimeout(function () {
            $(".reviews-page-carousel").slick(options)
        }, 500);
    }
})

Do not initialize slick slider at start. Just initialize after an AJAX with timeout. That should work for you.

go

Usage:

declare @liststr varchar(max)
select @liststr = dbo.group_concat_d(institutionname, ',')
from education
where studentnumber = '111'
group by studentnumber;
select @liststr

GroupConcat does not support ordering, though. You could use PIVOT, CTE's and windows functions if you need ordering:

drop table if exists #students;
create table #students (
    name        varchar(20),
    institution varchar(20),
    year        int -- order by year
)
go

insert into #students(name, institution, year)
values
    ('Simon', 'INSTITUTION1', 2005),
    ('Simon', 'INSTITUTION2', 2008);

with cte as (
    select name,
           institution,
           rn = row_number() over (partition by name order by year)
    from #students
)
select name,
       [1] +
       isnull((',' + [2]), '') +
       isnull((',' + [3]), '') +

<div><i class="fa fa-circle" aria-hidden="true"></i></div>

Just wanted to mention another solution which answers the question of "Easier way to create circle div than using an image?" which is to use FontAwesome.

You import the fontawesome css file or from the CDN here

and then you just:

<div><i class="fa fa-circle" aria-hidden="true"></i></div>

and you can give it any color you want any font size.

The magic method __getitem__ is basically used for accessing list items, dictionary entries, array elements etc. It is very useful for a quick lookup of instance attributes.

Here I am showing this with an example class Person that can be instantiated by 'name', 'age', and 'dob' (date of birth). The __getitem__ method is written in a way that one can access the indexed instance attributes, such as first or last name, day, month or year of the dob, etc.

import copy

# Constants that can be used to index date of birth's Date-Month-Year
D = 0; M = 1; Y = -1

class Person(object):
    def __init__(self, name, age, dob):
        self.name = name
        self.age = age
        self.dob = dob

    def __getitem__(self, indx):
        print ("Calling __getitem__")
        p = copy.copy(self)

        p.name = p.name.split(" ")[indx]
        p.dob = p.dob[indx] # or, p.dob = p.dob.__getitem__(indx)
        return p

Suppose one user input is as follows:

p = Person(name = 'Jonab Gutu', age = 20, dob=(1, 1, 1999))

With the help of __getitem__ method, the user can access the indexed attributes. e.g.,

print p[0].name # print first (or last) name
print p[Y].dob  # print (Date or Month or ) Year of the 'date of birth'

Online tools to translate Apache .htaccess to Nginx rewrite tools include:

• http://winginx.com/htaccess
• http://www.anilcetin.com/convert-apache-htaccess-to-nginx/

Note that these tools will convert to equivalent rewrite expressions using if statements, but they should be converted to try_files. See:

• http://wiki.nginx.org/NginxHttpCoreModule#try_files

Well this worked for me

rvm pkg install openssl
rvm reinstall 1.9.2 --with-openssl-dir=$rvm_path/usr

Something is wrong with openssl implementation of my ubuntu 12.04

Use, a global variable or property for assigning the value to the textbox, give the value for the variable in another class and assign it to the textbox.text in form class.

When a web page is loaded, the browser creates a Document Object Model of the page.

The HTML DOM model is constructed as a tree of Objects:

With the object model, JavaScript gets all the power it needs to create dynamic HTML:

• JavaScript can change all the HTML elements in the page
• JavaScript can change all the HTML attributes in the page
• JavaScript can change all the CSS styles in the page
• JavaScript can remove existing HTML elements and attributes
• JavaScript can add new HTML elements and attributes
• JavaScript can react to all existing HTML events in the page
• JavaScript can create new HTML events on the page

You can create a two variables of datetime, and set only hour of date that your need to compare.

declare  @date1 datetime;
declare  @date2 datetime;

select   @date1 = CONVERT(varchar(20),CONVERT(datetime, '2011-02-11 08:00:00'), 114)
select   @date2 = CONVERT(varchar(20),GETDATE(), 114)

The date will be "1900-01-01" you can compare it

if @date1 <= @date2
   print '@date1 less then @date2'
else
   print '@date1 more then @date2'

You can use String formatting for the double type. Here is an example:

double val = 58.6547;
String.Format("{0:0.##}", val);      
//Output: "58.65"

double val = 58.6;
String.Format("{0:0.##}", val);      
//Output: "58.6"

double val = 58.0;
String.Format("{0:0.##}", val);      
//Output: "58"

Let me know if this doesn't help.

The quick and dirty way is using json_encode and json_decode which will turn the entire array (including sub elements) into an object.

$clasa = json_decode(json_encode($clasa)); //Turn it into an object

The same can be used to convert an object into an array. Simply add , true to json_decode to return an associated array:

$clasa = json_decode(json_encode($clasa), true); //Turn it into an array

An alternate way (without being dirty) is simply a recursive function:

function convertToObject($array) {
    $object = new stdClass();
    foreach ($array as $key => $value) {
        if (is_array($value)) {
            $value = convertToObject($value);
        }
        $object->$key = $value;
    }
    return $object;
}

or in full code:

<?php
    function convertToObject($array) {
        $object = new stdClass();
        foreach ($array as $key => $value) {
            if (is_array($value)) {
                $value = convertToObject($value);
            }
            $object->$key = $value;
        }
        return $object;
    }

    $clasa = array(
            'e1' => array('nume' => 'Nitu', 'prenume' => 'Andrei', 'sex' => 'm', 'varsta' => 23),
            'e2' => array('nume' => 'Nae', 'prenume' => 'Ionel', 'sex' => 'm', 'varsta' => 27),

            'e5' => array('nume' => 'Vasile', 'prenume' => 'Mihai', 'sex' => 'm', 'varsta' => 25)
    );

    $obj = convertToObject($clasa);
    print_r($obj);
?>

which outputs (note that there's no arrays - only stdClass's):

stdClass Object
(
    [e1] => stdClass Object
        (
            [nume] => Nitu
            [prenume] => Andrei
            [sex] => m
            [varsta] => 23
        )

    [e2] => stdClass Object
        (
            [nume] => Nae
            [prenume] => Ionel
            [sex] => m
            [varsta] => 27
        )

    [e3] => stdClass Object
        (
            [nume] => Noman
            [prenume] => Alice
            [sex] => f
            [varsta] => 22
        )

    [e4] => stdClass Object
        (
            [nume] => Geangos
            [prenume] => Bogdan
            [sex] => m
            [varsta] => 23
        )

    [e5] => stdClass Object
        (
            [nume] => Vasile
            [prenume] => Mihai
            [sex] => m
            [varsta] => 25
        )

)

So you'd refer to it by $obj->e5->nume.

With Java 8 it can be cloned with a stream.

import static java.util.stream.Collectors.toList;

...

List<AnObject> clone = myList.stream().collect(toList());

I would suggest the following code:

<div id="example" onClick="colorize()">Click on this text to change the
background color</div>
<script type='text/javascript'>
function colorize() {
var element = document.getElementById("example");
element.style.backgroundColor='#800';
element.style.color='white';
element.style.textAlign='center';
}
</script>

Set

html { height: 100%; }
body { min-height: 100%; }

instead of height: 100%.

The result jQuery returns is correct, because you've set the height of the body to 100%, and that's probably the height of the viewport. These three DIVs were causing an overflow, because there weren't enough space for them in the BODY element. To see what I mean, set a border to the BODY tag and check where the border ends.

perlfaq8 answers a very similar question with using the rel2abs() function on $0. That function can be found in File::Spec.

success only fires if the AJAX call is successful, i.e. ultimately returns a HTTP 200 status. error fires if it fails and complete when the request finishes, regardless of success.

In jQuery 1.8 on the jqXHR object (returned by $.ajax) success was replaced with done, error with fail and complete with always.

However you should still be able to initialise the AJAX request with the old syntax. So these do similar things:

// set success action before making the request
$.ajax({
  url: '...',
  success: function(){
    alert('AJAX successful');
  }
});

// set success action just after starting the request
var jqxhr = $.ajax( "..." )
  .done(function() { alert("success"); });

This change is for compatibility with jQuery 1.5's deferred object. Deferred (and now Promise, which has full native browser support in Chrome and FX) allow you to chain asynchronous actions:

$.ajax("parent").
    done(function(p) { return $.ajax("child/" + p.id); }).
    done(someOtherDeferredFunction).
    done(function(c) { alert("success: " + c.name); });

This chain of functions is easier to maintain than a nested pyramid of callbacks you get with success.

However, please note that done is now deprecated in favour of the Promise syntax that uses then instead:

$.ajax("parent").
    then(function(p) { return $.ajax("child/" + p.id); }).
    then(someOtherDeferredFunction).
    then(function(c) { alert("success: " + c.name); }).
    catch(function(err) { alert("error: " + err.message); });

This is worth adopting because async and await extend promises improved syntax (and error handling):

try {
    var p = await $.ajax("parent");
    var x = await $.ajax("child/" + p.id);
    var c = await someOtherDeferredFunction(x);
    alert("success: " + c.name);
}
catch(err) { 
    alert("error: " + err.message); 
}

Setting or Updating of Reactive Forms Form Control values can be done using both patchValue and setValue. However, it might be better to use patchValue in some instances.

patchValue does not require all controls to be specified within the parameters in order to update/set the value of your Form Controls. On the other hand, setValue requires all Form Control values to be filled in, and it will return an error if any of your controls are not specified within the parameter.

In this scenario, we will want to use patchValue, since we are only updating user and questioning:

this.qService.editQue([params["id"]]).subscribe(res => {
  this.question = res;
  this.editqueForm.patchValue({
    user: this.question.user,
    questioning: this.question.questioning
  });
});

EDIT: If you feel like doing some of ES6's Object Destructuring, you may be interested to do this instead

const { user, questioning } = this.question;

this.editqueForm.patchValue({
  user,
  questioning
});

Ta-dah!

In my case I ran on this problem while using Edge.js — all the problem was a JavaScript syntax error inside a C# Edge.js function definition.

rysnc can be useful to run on slow and unreliable connections. So if your download aborts in the middle of a large file rysnc will be able to continue from where it left off when invoked again.

Use rsync -vP username@host:/path/to/file .

The -P option preserves partially downloaded files and also shows progress.

As usual check man rsync

I've improved Josh's answer. I've noticed that dig only shows entries already present in the queried nameserver's cache, so it's better to pull an authoritative nameserver from the SOA (rather than rely on the default nameserver). I've also disabled the filtering of wildcard IPs because usually I'm usually more interested in the correctness of the setup.

The new script takes a -x argument for expanded output and a -s NS argument to choose a specific nameserver: dig -x example.com

#!/bin/bash
set -e; set -u
COMMON_SUBDOMAINS="www mail mx a.mx smtp pop imap blog en ftp ssh login"
EXTENDED=""

while :; do case "$1" in
  --) shift; break ;;
  -x) EXTENDED=y; shift ;;
  -s) NS="$2"; shift 2 ;;
  *) break ;;
esac; done
DOM="$1"; shift
TYPE="${1:-any}"

test "${NS:-}" || NS=$(dig +short  SOA "$DOM" | awk '{print $1}')
test "$NS" && NS="@$NS"

if test "$EXTENDED"; then
  dig +nocmd $NS "$DOM" +noall +answer "$TYPE"
  wild_ips=$(dig +short "$NS" "*.$DOM" "$TYPE" | tr '\n' '|')
  wild_ips="${wild_ips%|}"
  for sub in $COMMON_SUBDOMAINS; do
    dig +nocmd $NS "$sub.$DOM" +noall +answer "$TYPE"
  done | cat  #grep -vE "${wild_ips}"
  dig +nocmd $NS "*.$DOM" +noall +answer "$TYPE"
else
  dig +nocmd $NS "$DOM" +noall +answer "$TYPE"
fi

Exception object also contains original response e.response, that could be useful if need to see error body in response from the server. For example:

try:
    r = requests.post('somerestapi.com/post-here', data={'birthday': '9/9/3999'})
    r.raise_for_status()
except requests.exceptions.HTTPError as e:
    print (e.response.text)

While it's true that virtual is the de-facto standard to define an interface, let's not forget about the classic C-like pattern, which comes with a constructor in C++:

struct IButton
{
    void (*click)(); // might be std::function(void()) if you prefer

    IButton( void (*click_)() )
    : click(click_)
    {
    }
};

// call as:
// (button.*click)();

This has the advantage that you can re-bind events runtime without having to construct your class again (as C++ does not have a syntax for changing polymorphic types, this is a workaround for chameleon classes).

Tips:

• You might inherit from this as a base class (both virtual and non-virtual are permitted) and fill click in your descendant's constructor.
• You might have the function pointer as a protected member and have a public reference and/or getter.
• As mentioned above, this allows you to switch the implementation in runtime. Thus it's a way to manage state as well. Depending on the number of ifs vs. state changes in your code, this might be faster than switch()es or ifs (turnaround is expected around 3-4 ifs, but always measure first.
• If you choose std::function<> over function pointers, you might be able to manage all your object data within IBase. From this point, you can have value schematics for IBase (e.g., std::vector<IBase> will work). Note that this might be slower depending on your compiler and STL code; also that current implementations of std::function<> tend to have an overhead when compared to function pointers or even virtual functions (this might change in the future).

Don't do this use a dictionary

import sys
this = sys.modules[__name__] # this is now your current namespace
for x in range(0,9):
    setattr(this, 'string%s' % x, 'Hello')

print string0
print string1
print string2
print string3
print string4
print string5
print string6
print string7
print string8

don't do this use a dict

globals() has risk as it gives you what the namespace is currently pointing to but this can change and so modifying the return from globals() is not a good idea

The time.Parse function does not do Unix timestamps. Instead you can use strconv.ParseInt to parse the string to int64 and create the timestamp with time.Unix:

package main

import (
    "fmt"
    "time"
    "strconv"
)

func main() {
    i, err := strconv.ParseInt("1405544146", 10, 64)
    if err != nil {
        panic(err)
    }
    tm := time.Unix(i, 0)
    fmt.Println(tm)
}

Output:

2014-07-16 20:55:46 +0000 UTC

Playground: http://play.golang.org/p/v_j6UIro7a

Edit:

Changed from strconv.Atoi to strconv.ParseInt to avoid int overflows on 32 bit systems.

Another possible solution is to compare current date with January 1, 1970, you can get January 1, 1970 by new Date(0);

var date = new Date(); 
var myDate= date - new Date(0);

It says

Cannot find module 'express'

Do you have express installed? If not then run this.

npm install express

and run your program again.

let's suppose the new and untracked file is called: "views.json". if you want to change branch by stashing the state of your app, I generally type:

git add views.json

Then:

git stash

And it would be stashed. Then I can just change branch with

git checkout other-nice-branch

Probably already too late to answer but since you have already parse the dates while loading the data, you can just do this to get the day

df['date'] = pd.DatetimeIndex(df['date']).year

Here is a version based on the accepted answer. It fixes two problems...

1. Improper disposing of the images.
2. Maintaining the aspect ratio of the image.

I found this tool to be fast and effective for both JPG and PNG files.

private static FileInfo CreateThumbnailImage(string imageFileName, string thumbnailFileName)
{
    const int thumbnailSize = 150;
    using (var image = Image.FromFile(imageFileName))
    {
        var imageHeight = image.Height;
        var imageWidth = image.Width;
        if (imageHeight > imageWidth)
        {
            imageWidth = (int) (((float) imageWidth / (float) imageHeight) * thumbnailSize);
            imageHeight = thumbnailSize;
        }
        else
        {
            imageHeight = (int) (((float) imageHeight / (float) imageWidth) * thumbnailSize);
            imageWidth = thumbnailSize;
        }

        using (var thumb = image.GetThumbnailImage(imageWidth, imageHeight, () => false, IntPtr.Zero))
            //Save off the new thumbnail
            thumb.Save(thumbnailFileName);
    }

    return new FileInfo(thumbnailFileName);
}

I guess what you're looking for is pyquery:

pyquery: a jquery-like library for python.

An example of what you want may be like:

from pyquery import PyQuery    
html = # Your HTML CODE
pq = PyQuery(html)
tag = pq('div#id') # or     tag = pq('div.class')
print tag.text()

And it uses the same selectors as Firefox's or Chrome's inspect element. For example:

The inspected element selector is 'div#mw-head.noprint'. So in pyquery, you just need to pass this selector:

pq('div#mw-head.noprint')

My own __init__.py files are empty more often than not. In particular, I never have a from blah import * as part of __init__.py -- if "importing the package" means getting all sort of classes, functions etc defined directly as part of the package, then I would lexically copy the contents of blah.py into the package's __init__.py instead and remove blah.py (the multiplication of source files does no good here).

If you do insist on supporting the import * idioms (eek), then using __all__ (with as miniscule a list of names as you can bring yourself to have in it) may help for damage control. In general, namespaces and explicit imports are good things, and I strong suggest reconsidering any approach based on systematically bypassing either or both concepts!-)

Here is a function that tells if an element is in visible in the current viewport of a parent element:

function inParentViewport(el, pa) {
    if (typeof jQuery === "function"){
        if (el instanceof jQuery)
            el = el[0];
        if (pa instanceof jQuery)
            pa = pa[0];
    }

    var e = el.getBoundingClientRect();
    var p = pa.getBoundingClientRect();

    return (
        e.bottom >= p.top &&
        e.right >= p.left &&
        e.top <= p.bottom &&
        e.left <= p.right
    );
}

//HashSet allows only the unique values to the list
HashSet<int> uniqueList = new HashSet<int>();

var a = uniqueList.Add(1);
var b = uniqueList.Add(2);
var c = uniqueList.Add(3);
var d = uniqueList.Add(2); // should not be added to the list but will not crash the app

//Dictionary allows only the unique Keys to the list, Values can be repeated
Dictionary<int, string> dict = new Dictionary<int, string>();

dict.Add(1,"Happy");
dict.Add(2, "Smile");
dict.Add(3, "Happy");
dict.Add(2, "Sad"); // should be failed // Run time error "An item with the same key has already been added." App will crash

//Dictionary allows only the unique Keys to the list, Values can be repeated
Dictionary<string, int> dictRev = new Dictionary<string, int>();

dictRev.Add("Happy", 1);
dictRev.Add("Smile", 2);
dictRev.Add("Happy", 3); // should be failed // Run time error "An item with the same key has already been added." App will crash
dictRev.Add("Sad", 2);

PostgreSQL supports boolean types, so your SQL query would work perfectly in PostgreSQL.

This might sound silly, but make sure the "Offline" checkbox in Maven settings is unchecked. I was trying to create a project and got this error until I noticed the checkbox.

If it is possible for you to use your own list bullets

Try this:

<html>
    <head>
        <style type="text/css">

            ul {
                margin:0;
                padding:0;
                text-align: center;
                list-style:none;                
            }
            ul  li {
                padding: 2px 5px;               
            }

            ul li:before {
                content:url(http://www.un.org/en/oaj/unjs/efiling/added/images/bullet-list-icon-blue.jpg);;
            }
        </style>
    </head>
    <body>

            <ul>
                <li>1</li>
                <li>2</li>
                <li>3</li>
            </ul>

    </body>
</html>

That selects the row number per country code, account, and currency. So, the rows with country code "US", account "XYZ" and currency "$USD" will each get a row number assigned from 1-n; the same goes for every other combination of those columns in the result set.

This query is kind of funny, because the order by clause does absolutely nothing. All the rows in each partition have the same country code, account, and currency, so there's no point ordering by those columns. The ultimate row numbers assigned in this particular query will therefore be unpredictable.

Hope that helps...

To generate graph in png format you need to Install following dependent packages

sudo apt-get install libpng-dev
sudo apt-get install libfreetype6-dev

Ubuntu https://apps.ubuntu.com/cat/applications/libpng12-0/ or using following command

sudo apt-get install libpng12-0

try to implement Application_AuthenticateRequest instead of Application_Start.

this method has an instance for HttpContext.Current, unlike Application_Start (which fires very soon in app lifecycle, soon enough to not hold a HttpContext.Current object yet).

hope that helps.

I had the same problem with STS (springtool source suite).

Under STS, right click on the project, than "Properties", "Project Facets", than on the right of the window click on the "runtime" tab, and check "VMware vFabric tc Server (...)", and click "Apply" and it should be OK after the workspace refresh.

check the base package name.If the package has different modules that are not prefixed with base package name.

Using variables in if statements

if [ "$x" = "valid" ]; then
  echo "x has the value 'valid'"
fi

If you want to do something when they don't match, replace = with !=. You can read more about string operations and arithmetic operations in their respective documentation.

Why do we use quotes around $x?

You want the quotes around $x, because if it is empty, your Bash script encounters a syntax error as seen below:

if [ = "valid" ]; then

Non-standard use of == operator

Note that Bash allows == to be used for equality with [, but this is not standard.

Use either the first case wherein the quotes around $x are optional:

if [[ "$x" == "valid" ]]; then

or use the second case:

if [ "$x" = "valid" ]; then

find /path/to/ -type f -print0 | xargs -0 file | grep -i image

This uses the file command to try to recognize the type of file, regardless of filename (or extension).

If /path/to or a filename contains the string image, then the above may return bogus hits. In that case, I'd suggest

cd /path/to
find . -type f -print0 | xargs -0 file --mime-type | grep -i image/

In C++ you can use EscapeXML ATL API. This is the correct way of handling special chars ...

Edit. As noted in the comments, this is no longer working with the latest Android Studio releases.

The latest Android studio seems to only reference to "Offline mode" via the keymap, but toggling this does not seem to change anything anymore.

In Android Studio open the settings and search for offline it will find the Gradle category which contains Offline work. You can disable it there.

Resolution:

Refer to this link: As there are various options to shut the warning off depending on the minSdkVersion, it is set below 20:

 android {
     defaultConfig {
         ...
         minSdkVersion 15 
         targetSdkVersion 26
         multiDexEnabled true
     }
     ... }

 dependencies {   compile 'com.android.support:multidex:1.0.3' }

If you have a minSdkVersion greater than 20 in your build.gradle set use the following to shut down the warning:

  android {
      defaultConfig {
          ...
          minSdkVersion 21 
          targetSdkVersion 26
          multiDexEnabled true
      }
      ... }

Update dependencies as follows:

     dependencies {
        implementation 'com.android.support:multidex:1.0.3'
     }

Again the only difference is the keywords in dependencies:

minSdkVersion below 20: use compile

minSdkVersion above 20: use implementation

1. I hope this was helpful, please upvote if it solved your issue, Thank you for your time.
2. Also for more info, on why this occurs, please read the first paragraph in the link, it will explain thoroughly why? and what does this warning mean.

Edit:

Are you trying to do sth like this? See: http://twitter.github.com/bootstrap/javascript.html#tabs

See the working example: http://jsfiddle.net/U6aKT/

<a href="#id">go to id</a>
<div style="margin-top:2000px;"></div>
<a id="id">id</a>

string _connString = "metadata=res://*/Model.csdl|res://*/Model.ssdl|res://*/Model.msl;provider=System.Data.SqlClient;provider connection string="data source=localhost;initial catalog=DATABASE;persist security info=True;user id=sa;password=YourPassword;multipleactiveresultsets=True;App=EntityFramework"";

EntityConnectionStringBuilder ecsb = new EntityConnectionStringBuilder(_connString);
ctx = new Entities(_connString);

You can get the connection string from the web.config, and just set that in the EntityConnectionStringBuilder constructor, and use the EntityConnectionStringBuilder as an argument in the constructor for the context.

Cache the connection string by username. Simple example using a couple of generic methods to handle adding/retrieving from cache.

private static readonly ObjectCache cache = MemoryCache.Default;

// add to cache
AddToCache<string>(username, value);

// get from cache

 string value = GetFromCache<string>(username);
 if (value != null)
 {
     // got item, do something with it.
 }
 else
 {
    // item does not exist in cache.
 }


public void AddToCache<T>(string token, T item)
    {
        cache.Add(token, item, DateTime.Now.AddMinutes(1));
    }

public T GetFromCache<T>(string cacheKey) where T : class
    {
        try
        {
            return (T)cache[cacheKey];
        }
        catch
        {
            return null;
        }
    }

I was experiencing this issue on a drupal site and none of the other solutions in this thread helped. After some troubleshooting I found the local.settings.php had a closing tag with a space after it like so:

<?php
$databases = array(
  'default' =>
  array (
    'default' =>
    array (
      'driver' => 'mysql',
      'database' => 'xxx',
      'username' => 'xxx',
      'password' => 'xxx',
      'port' => '',
      'host' => 'xxx',
    ),
  ),
);
?>
 

Updating local.settings.php to the following resolved:

<?php
$databases = array(
  'default' =>
  array (
    'default' =>
    array (
      'driver' => 'mysql',
      'database' => 'xxx',
      'username' => 'xxx',
      'password' => 'xxx',
      'port' => '',
      'host' => 'xxx',
    ),
  ),
);

The closing "?>" PHP tag is not necessary here. If you choose to use a closing tag you must ensure there are no characters / whitespace after it.

That worked for me:

$ export LC_ALL=en_US.UTF-8
$ export LANG=en_US.UTF-8

After some search for a solution it turns out the -dev package is needed, not just ruby1.8. So if you have ruby1.9.1 doing

sudo apt-get install ruby1.9.1-dev

or to install generic ruby version, use (as per @lamplightdev comment):

sudo apt-get install ruby-dev

should fix it.

Try locate mkmf to see if the file is actually there.

datatable.rows().iterator('row', function ( context, index ) {
    var data = this.row(index).data();
    var row = $(this.row(index).node());
    data[0] = 'new data';
    datatable.row(row).data(data).draw();
});

Bug with GLIBCXX_3.4.14 You need to install a newer version of GCC. http://pkgs.org/download/libstdc++.so.6 goto:

Hi friends, follow the steps to fix this issue in MAC OS

• Step 1: first run the command in Terminal with your project directory

  $ curl -sS https://getcomposer.org/installer | php

• Step 2: Move the composer.phar in your project directory

  $ mv composer.phar /Applications/MAMP/htdocs/bashrushAPI/composer.phar

• Step 3: Setup alias the composer

  $ alias composer='/Applications/MAMP/htdocs/bashrushAPI/composer.phar'

• Step 4: Check the composer version now

  $ composer --version

  Composer version 1.7.2 2018-08-16 16:57:12

• Step 5: Confirm the project folders and file placed on bellow

  $ ls

  CONTRIBUTING.md docker-compose.yml templates README.md logs tests composer.json phpunit.xml vendor composer.lock public composer.phar src

• Step 6: Now update composer

  $ composer.phar update

  Loading composer repositories with package information Updating dependencies (including require-dev) Nothing to install or update Generating autoload files

• Step 7: Run your sample project

  $ php composer.phar start

  php -S localhost:8080 -t public [Thu Sep 27 03:16:11 2018] ::1:51177 [200]: / [Thu Sep 27 03:16:11 2018] ::1:51178 [404]: /favicon.ico - No such file or directory

I needed my ASP.NET drop down list to take up all available space, and this is all I put in the CSS and it is working in Firefox and IE11:

width: 100%

I had to add the CSS class into the asp:DropDownList element

For a version with pure Bash and without test, but really ugly, try:

if ( exit "${s1/*$s2*/0}" )2>/dev/null
then
   echo match
fi

Explanation: In ( )an extra subshell is opened. It exits with 0 if there was a match, and it tries to exit with $s1 if there was no match which raises an error (ugly). This error is directed to /dev/null.

 <script> var disabledDaysRange = $disabledDaysRange ???? Please Help;
 $(function() {
     function disableRangeOfDays(d) {

in the above assign array to javascript variable "disableDaysRange"

$disallowDates = "";
echo "[";
foreach($disabledDaysRange as $disableDates){
 $disallowDates .= "'".$disableDates."',";
}

echo substr(disallowDates,0,(strlen(disallowDates)-1)); // this will escape the last comma from $disallowDates
echo "];";

so your javascript var diableDateRange shoudl be 

var diableDateRange = ["2013-01-01","2013-01-02","2013-01-03"];

You can use the border and box-shadow properties along with CSS pseudo elements to achieve a triple-border sort of effect. See the example below for an idea of how to create three borders at the bottom of a div:

.triple-border:after {_x000D_
    content: " ";_x000D_
    display: block;_x000D_
    width: 100%;_x000D_
    background: #FFE962;_x000D_
    height: 9px;_x000D_
    padding-bottom: 8px;_x000D_
    border-bottom: 9px solid #A3C662;_x000D_
    box-shadow: -2px 11px 0 -1px #34b6af;_x000D_
}

<div class="triple-border">Triple border bottom with multiple colours</div>

You'll have to play around with the values to get the alignment correct. However, you can also achieve more flexibility, e.g. 4 borders if you put some of the attributes in the proper element rather than the pseudo selector.

As @Renan mentioned, ng-include creates a new child scope. This scope prototypically inherits (see dashed lines below) from the HomeCtrl scope. ng-model="lineText" actually creates a primitive scope property on the child scope, not HomeCtrl's scope. This child scope is not accessible to the parent/HomeCtrl scope:

To store what the user typed into HomeCtrl's $scope.lines array, I suggest you pass the value to the addLine function:

 <form ng-submit="addLine(lineText)">

In addition, since lineText is owned by the ngInclude scope/partial, I feel it should be responsible for clearing it:

 <form ng-submit="addLine(lineText); lineText=''">

Function addLine() would thus become:

$scope.addLine = function(lineText) {
    $scope.chat.addLine(lineText);
    $scope.lines.push({
        text: lineText
    });
};

Fiddle.

Alternatives:

• define an object property on HomeCtrl's $scope, and use that in the partial: ng-model="someObj.lineText; fiddle
• not recommended, this is more of a hack: use $parent in the partial to create/access a lineText property on the HomeCtrl $scope:  ng-model="$parent.lineText"; fiddle

It is a bit involved to explain why the above two alternatives work, but it is fully explained here: What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

I don't recommend using this in the addLine() function. It becomes much less clear which scope is being accessed/manipulated.

Reading from specific line:

n = 4   # for reading from 5th line
with open("write.txt",'r') as t:
     for i,line in enumerate(t):
         if i >= n:             # i == n-1 for nth line
            print(line)

Rather than mess with the encode and decode methods I find it easier to specify the encoding when opening the file. The io module (added in Python 2.6) provides an io.open function, which has an encoding parameter.

Use the open method from the io module.

>>>import io
>>>f = io.open("test", mode="r", encoding="utf-8")

Then after calling f's read() function, an encoded Unicode object is returned.

>>>f.read()
u'Capit\xe1l\n\n'

Note that in Python 3, the io.open function is an alias for the built-in open function. The built-in open function only supports the encoding argument in Python 3, not Python 2.

Edit: Previously this answer recommended the codecs module. The codecs module can cause problems when mixing read() and readline(), so this answer now recommends the io module instead.

Use the open method from the codecs module.

>>>import codecs
>>>f = codecs.open("test", "r", "utf-8")

Then after calling f's read() function, an encoded Unicode object is returned.

>>>f.read()
u'Capit\xe1l\n\n'

If you know the encoding of a file, using the codecs package is going to be much less confusing.

See http://docs.python.org/library/codecs.html#codecs.open

substr: It's providing us to fetch part of the string based on specified index. syntax of substr- string.substr(start,end) start - start index tells where the fetching start. end - end index tells upto where string fetches. It's optional.

slice: It's providing to fetch part of the string based on the specified index. It's allows us to specify positive and index. syntax of slice - string.slice(start,end) start - start index tells where the fetching start.It's end - end index tells upto where string fetches. It's optional. In 'splice' both start and end index helps to take positive and negative index.

sample code for 'slice' in string

var str="Javascript";
console.log(str.slice(-5,-1));

output: crip

sample code for 'substring' in string

var str="Javascript";
console.log(str.substring(1,5));

output: avas

[*Note: negative indexing starts at the end of the string.]

Warning! Particularly simple answer below! :)

You actually can have a change that persists (such as a block/popup that appears and stays visible after a click) with only CSS (and without using the checkbox hack) despite what many of the (otherwise correct) answers here claim, as long as you only need persistence during the hover.

So take a look at Bojangles and TylerH's answers if those work for you, but if you want a simple and CSS only answer that will keep a block visible after being clicked on (and even can have the block disappear with a followup click), then see this solution.

I had a similar situation, I needed a popup div with onClick where I couldn't add any JS or change the markup/HTML (a truly CSS solution) and this is possible with some caveats. You can't use the :target trick that can create a nice popup unless you can change the HTML (to add an 'id') so that was out.

In my case the popup div was contained inside the other div, and I wanted the popup to appear on top of the other div, and this can be done using a combination of :active and :hover:

/* Outer div - needs to be relative so we can use absolute positioning */
.clickToShowInfo {
    position: relative;
}
/* When clicking outer div, make inner div visible */
.clickToShowInfo:active .info { display: block; }
/* And hold by staying visible on hover */
.info:hover {
    display: block;
}
/* General settings for popup */
.info {
    position: absolute;
    top: -5;
    display: none;
    z-index: 100;
    background-color: white;
    width: 200px;
    height: 200px;
}

Example (as well as one that allows clicking on the popup to make it disappear) at:

http://davesource.com/Solutions/20150324.CSS-Only-Click-to-Popup-Div/

I've also inserted a code snippet example below, but the positioning in the stackoverflow sandbox is weird so I had to put the 'click here' text after the innerDiv, which isn't normally needed.

/* Outer div - needs to be relative so we can use absolute positioning */_x000D_
 .clickToShowInfo {_x000D_
  position: relative;_x000D_
 }_x000D_
 /* When clicking outer div, make inner div visible */_x000D_

VC Code Version: 1.22.2 Go to: Code -> Preferences -> Keyboard Shortcuts (cmd + K; cms + S); Change (edit): "Add Selection To Next Find Match": "cmd + what you want" // for me this is "cmd + D" and I pur cmd + F; Go to "Copy Line Down": "cmd + D" //edit this and set cmd + D for example And for me that's all - I use mac;

I have used the following before:

var my_form = $('#form-id');
var data = {};

$('input:not([type=checkbox]), input[type=checkbox]:selected, select, textarea', my_form).each(
    function() {
        var name = $(this).attr('name');
        var val = $(this).val();

        if (!data.hasOwnProperty(name)) {
            data[name] = new Array;
        }

        data[name].push(val);
    }
);

This is just written from memory, so might contain mistakes, but this should make an object called data that contains the values for all your inputs.

Note that you have to deal with checkboxes in a special way, to avoid getting the values of unchecked checkboxes. The same is probably true of radio inputs.

Also note using arrays for storing the values, as for one input name, you might have values from several inputs (checkboxes in particular).

You've still got a margin on your h1 tag

So you need to remove that like this:

h1 {
 margin-top:0;
}

1. Please check current version of your Kotlin in below path,

   C:\Program Files\Android\Android Studio\gradle\m2repository\org\jetbrains\kotlin\kotlin-stdlib\1.0.5

change to that version (1.0.5) in project level gradle file.

You can see in your above path does not mentioned any Java - jre version, so remove in your app level gradle file as below,

compile "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"

Put this at the top of the file:

var console = {};
console.log = function(){};

For some browsers and minifiers, you may need to apply this onto the window object.

window.console = console;

You can overload the method with different parameters:

public int doSomething(int arg1, int arg2)
{
//some logic here
        return 0;
}

public int doSomething(
{
doSomething(0,0)
}

LEFT ('BTA200', 3) will work for the examples you have given, as in :

SELECT LEFT(MyField, 3)
FROM MyTable

To extract the numeric part, you can use this code

SELECT RIGHT(MyField, LEN(MyField) - 3)
FROM MyTable
WHERE MyField LIKE 'BTA%' 
--Only have this test if your data does not always start with BTA.

It depend on your access right but for me this work on phpmyadmin sql console

SHOW VARIABLES;

then after to change some variables you can do

SET GLOBAL max_connections = 1000;

or

SET @@GLOBAL.max_connections = 1000;

give a try

You may want to try the following:

SELECT    CONCAT(title, ' ', forename, ' ', surname) AS name
FROM      customer c
JOIN      (
              SELECT    MAX(id) max_id, customer_id 
              FROM      customer_data 
              GROUP BY  customer_id
          ) c_max ON (c_max.customer_id = c.customer_id)
JOIN      customer_data cd ON (cd.id = c_max.max_id)
WHERE     CONCAT(title, ' ', forename, ' ', surname) LIKE '%Smith%' 
LIMIT     10, 20;

Note that a JOIN is just a synonym for INNER JOIN.

Test case:

CREATE TABLE customer (customer_id int);
CREATE TABLE customer_data (
   id int, 
   customer_id int, 
   title varchar(10),
   forename varchar(10),
   surname varchar(10)
);

INSERT INTO customer VALUES (1);
INSERT INTO customer VALUES (2);
INSERT INTO customer VALUES (3);

INSERT INTO customer_data VALUES (1, 1, 'Mr', 'Bobby', 'Smith');
INSERT INTO customer_data VALUES (2, 1, 'Mr', 'Bob', 'Smith');
INSERT INTO customer_data VALUES (3, 2, 'Mr', 'Jane', 'Green');
INSERT INTO customer_data VALUES (4, 2, 'Miss', 'Jane', 'Green');
INSERT INTO customer_data VALUES (5, 3, 'Dr', 'Jack', 'Black');

Result (query without the LIMIT and WHERE):

SELECT    CONCAT(title, ' ', forename, ' ', surname) AS name
FROM      customer c
JOIN      (
              SELECT    MAX(id) max_id, customer_id 
              FROM      customer_data 
              GROUP BY  customer_id
          ) c_max ON (c_max.customer_id = c.customer_id)
JOIN      customer_data cd ON (cd.id = c_max.max_id);

+-----------------+

3 rows in set (0.00 sec)

You can solve this problem using this code:

if(!empty($_GET['variable from which you get'])) 
{
$_SESSION['something']= $_GET['variable from which you get'];
}

So you get the variable from a GET form, you will store in the $_SESSION['whatever'] variable just once when $_GET['variable from which you get']is set and if it is empty $_SESSION['something'] will store the old parameter

Here is the example for Immutable string and Mutable string builder

        Console.WriteLine("Mutable String Builder");
        Console.WriteLine("....................................");
        Console.WriteLine();
        StringBuilder sb = new StringBuilder("Very Good Morning");
        Console.WriteLine(sb.ToString());
        sb.Remove(0, 5);
        Console.WriteLine(sb.ToString());

        Console.WriteLine();

        Console.WriteLine("Immutable String");
        Console.WriteLine("....................................");
        Console.WriteLine();
        string s = "Very Good Morning";
        Console.WriteLine(s);
        s.Substring(0, 5);
        Console.WriteLine(s);
        Console.ReadLine();

If you have only these regular shapes, there is a simple procedure as follows :

1. Find Contours in the image ( image should be binary as given in your question)
2. Approximate each contour using approxPolyDP function.
3. First, check number of elements in the approximated contours of all the shapes. It is to recognize the shape. For eg, square will have 4, pentagon will have 5. Circles will have more, i don't know, so we find it. ( I got 16 for circle and 9 for half-circle.)
4. Now assign the color, run the code for your test image, check its number, fill it with corresponding colors.

Below is my example in Python:

import numpy as np
import cv2

img = cv2.imread('shapes.png')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

ret,thresh = cv2.threshold(gray,127,255,1)

contours,h = cv2.findContours(thresh,1,2)

for cnt in contours:
    approx = cv2.approxPolyDP(cnt,0.01*cv2.arcLength(cnt,True),True)
    print len(approx)
    if len(approx)==5:
        print "pentagon"
        cv2.drawContours(img,[cnt],0,255,-1)
    elif len(approx)==3:
        print "triangle"
        cv2.drawContours(img,[cnt],0,(0,255,0),-1)
    elif len(approx)==4:
        print "square"
        cv2.drawContours(img,[cnt],0,(0,0,255),-1)
    elif len(approx) == 9:
        print "half-circle"
        cv2.drawContours(img,[cnt],0,(255,255,0),-1)
    elif len(approx) > 15:
        print "circle"
        cv2.drawContours(img,[cnt],0,(0,255,255),-1)

cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Below is the output:

Remember, it works only for regular shapes.

Alternatively to find circles, you can use houghcircles. You can find a tutorial here.

Regarding iOS, OpenCV devs are developing some iOS samples this summer, So visit their site : www.code.opencv.org and contact them.

You can find slides of their tutorial here : http://code.opencv.org/svn/gsoc2012/ios/trunk/doc/CVPR2012_OpenCV4IOS_Tutorial.pdf

I add on Nick's question: when are hard links useful or necessary? The only application that comes to my mind, in which symbolic links wouldn't do the job, is providing a copy of a system file in a chrooted environment.

Lodash offers a similar functionality as the Javascript repeat() function which is not available in all browers. It is called _.repeat and available since version 3.0.0:

_.repeat('a', 10);

Shorter sample for json.net library.

using Newtonsoft.Json;

private static string format_json(string json)
{
    dynamic parsedJson = JsonConvert.DeserializeObject(json);
    return JsonConvert.SerializeObject(parsedJson, Formatting.Indented);
}

PS: You can wrap the formatted json text with tag to print as it is on the html page.

For Kotlin developers, remember the Java transient keyword becomes the built-in Kotlin @Transient annotation. Therefore, make sure you have the JPA import if you're using JPA @Transient in your entity:

import javax.persistence.Transient

Just use x["error_msg"]. If the property doesn't exist, it returns null.

If you're using a WebView you'll have to intercept the clicks yourself if you don't want the default Android behaviour.

You can monitor events in a WebView using a WebViewClient. The method you want is shouldOverrideUrlLoading(). This allows you to perform your own action when a particular URL is selected.

You set the WebViewClient of your WebView using the setWebViewClient() method.

If you look at the WebView sample in the SDK there's an example which does just what you want. It's as simple as:

private class HelloWebViewClient extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}

If I'm not mislead, you just need to set your local branches to track their pairs in the origin server.

Using your command line, you can try

git checkout mybranch
git branch --set-upstream-to=origin/mybranch

That will configure something as an equivalent of your local branch in the server. I'll bet that Android Studio is complaining about the lack of that.

If someone knows how to do this using the GUI of that IDE, that would be interesting to read. :)

On debian where bsd-mailx is installed by default, the -r option does not work. However you can use mailx -s subject [email protected] -- -f [email protected] instead. According to man page, you can specify sendmail options after --.

You can use DISTINCT inside the COUNT like what milkovsky said

in my case:

select COUNT(distinct user_id) from answers_votes where answer_id in (694,695);

This will pull the count of answer votes considered the same user_id as one count

You can Try using :- git ls-files -s

You can still name the DropDown as "UserId" and still have model binding working correctly for you.

The only requirement for this to work is that the ViewData key that contains the SelectList does not have the same name as the Model property that you want to bind. In your specific case this would be:

// in my controller
ViewData["Users"] = new SelectList(
    users, 
    "UserId", 
    "DisplayName", 
    selectedUserId.Value); // this has a value

// in my view
<%=Html.DropDownList("UserId", (SelectList)ViewData["Users"])%>

This will produce a select element that is named UserId, which has the same name as the UserId property in your model and therefore the model binder will set it with the value selected in the html's select element generated by the Html.DropDownList helper.

I'm not sure why that particular Html.DropDownList constructor won't select the value specified in the SelectList when you put the select list in the ViewData with a key equal to the property name. I suspect it has something to do with how the DropDownList helper is used in other scenarios, where the convention is that you do have a SelectList in the ViewData with the same name as the property in your model. This will work correctly:

// in my controller
ViewData["UserId"] = new SelectList(
    users, 
    "UserId", 
    "DisplayName", 
    selectedUserId.Value); // this has a value

// in my view
<%=Html.DropDownList("UserId")%>

I ran into the same situation where commands such as git diff origin or git diff origin master produced the error reported in the question, namely Fatal: ambiguous argument...

To resolve the situation, I ran the command

git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master

to set refs/remotes/origin/HEAD to point to the origin/master branch.

Before running this command, the output of git branch -a was:

* master
  remotes/origin/master

After running the command, the error no longer happened and the output of git branch -a was:

* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master

(Other answers have already identified that the source of the error is HEAD not being set for origin. But I thought it helpful to provide a command which may be used to fix the error in question, although it may be obvious to some users.)

Additional information:

For anybody inclined to experiment and go back and forth between setting and unsetting refs/remotes/origin/HEAD, here are some examples.

To unset:
git remote set-head origin --delete

To set:
(additional ways, besides the way shown at the start of this answer)
git remote set-head origin master to set origin/head explicitly
OR
git remote set-head origin --auto to query the remote and automatically set origin/HEAD to the remote's current branch.

Yes.

If the scrollbar is not the browser scrollbar, then it will be built of regular HTML elements (probably divs and spans) and can thus be styled (or will be Flash, Java, etc and can be customized as per those environments).

The specifics depend on the DOM structure used.

Have you forgotten to create a feature-branch and have committed directly on master by mistake?

You can create the feature branch now and set master back without affecting the worktree (local filesystem) to avoid triggering builds, tests and trouble with file-locks:

git checkout -b feature-branch
git branch -f master origin/master

To expand on the answer given by Chris

if you want to store the date in a variable in a specific format, this is the shortest and most effective way as far as I know

>>> from datetime import date, timedelta                   
>>> yesterday = (date.today() - timedelta(days=1)).strftime('%m%d%y')
>>> yesterday
'020817'

If you want it as an integer (which can be useful)

>>> yesterday = int((date.today() - timedelta(days=1)).strftime('%m%d%y'))
>>> yesterday
20817

The << part is wrong, use < instead:

$ ./manage.py shell < myscript.py

You could also do:

$ ./manage.py shell
...
>>> execfile('myscript.py')

For python3 you would need to use

>>> exec(open('myscript.py').read())

That's just the usual ternary operator. If the part before the question mark is true, it evaluates and returns the part before the colon, otherwise it evaluates and returns the part after the colon.

a?b:c

is like

if(a)
    b;
else
    c;

Hello all I see a lot of good options but I was wondering why Binding hasn't been used?

Passing a reference to an object just seems more efficient to me than serializing and desterilizing objects, but I have not done a deep dive to see if that is what is going on behind the scenes.

Creating a Binder is simple enough...

public class MyBinder extends Binder {

    private Object myObject;

    public MyBinder(Object object) {
        myObject = object;
    }

    public Object getObject() {
        return myObject;
    }

}

And creating the parcelable to use it isn't that bad ether.

public class MyParcelable implements Parcelable {

    private Object myObject;

    public MyParcelable() {
    }

    public MyParcelable(Parcel parcel) {
        myObject = ((MyBinder)parcel.readStrongBinder()).getObject();
    }

    public void setObject(Object object) {
        myObject = object;
    }

    public Object getObject() {
        return myObject;
    }

    public void writeToParcel(Parcel parcel, int flags) {
        parcel.writeStrongBinder(new MyBinder(myObject));
    }

    public int describeContents() {
        return myObject == null ? 0 : 1;
    }

    public static final Parcelable.Creator<MyParcelable> CREATOR = new Parcelable.Creator<MyParcelable>() {

        public MyParcelable createFromParcel(Parcel parcel) {
            return new MyParcelable(parcel);
        }

        public MyParcelable[] newArray(int length) {
            return new MyParcelable[length];
        }

    };
}

This logic is really cool because you are actually passing a reference from activity to activity.

I would advise checking for nulls and if the instanceof Binder is MyBinder!

and to implement this you just...

Send it off

Object myObject = "some object";
MyParcelable myParcelable = new MyParcelable();
myParcelable.setObject(myObject);

intent.putExtra("MyParcelable", myParcelable);

Get it back

myParcelable = (MyParcelable) getIntent().getExtras().getParcelable("MyParcelable");
myObject = myParcelable.getObject();

Heck someone could get all crazy and make this sucker a true generic.

This is essentially the answer that Yishai provided above, re-written in Kotlin :

@RunWith(Parameterized::class)
class MyTest {

    companion object {

        private const val numberOfTests = 200

        @JvmStatic
        @Parameterized.Parameters
        fun data(): Array<Array<Any?>> = Array(numberOfTests) { arrayOfNulls<Any?>(0) }
    }

    @Test
    fun testSomething() { }
}

I experienced the same problem and tried most of the resolutions above. Simply deleting cache and temp files end up working for me.

Try removing the contents of these two folders:

C:\Users\\{UserName}\AppData\Local\Microsoft\WebsiteCache

and

C:\Users\\{UserName}\AppData\Local\Temp (in particular the iisexpress and Temporary ASP.NET Files folders).

This can be set up to happen automatically on logging on to Windows by adding a cmd file to the C:\Users\\{username}\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup folder with the following content:

rmdir C:\Users\\{username}\AppData\Local\Microsoft\WebsiteCache /s /q

rmdir C:\Users\\{username}\AppData\Local\Temp /s /q

you can use getline from a file using this code. this code will take a whole line from the file. and then you can use a while loop to go all lines while (ins);

 ifstream ins(filename);
string s;
std::getline (ins,s);

The given answers stress the fact that emptyList() returns an immutable List but do not give alternatives. The Constructor ArrayList(int initialCapacity) special cases 0 so returning new ArrayList<>(0) instead of new ArrayList<>() might also be a viable solution:

/**
 * Shared empty array instance used for empty instances.
 */
private static final Object[] EMPTY_ELEMENTDATA = {};

[...]

/**
 * Constructs an empty list with the specified initial capacity.
 *
 * @param  initialCapacity  the initial capacity of the list
 * @throws IllegalArgumentException if the specified initial capacity
 *         is negative
 */
public ArrayList(int initialCapacity) {
    if (initialCapacity > 0) {
        this.elementData = new Object[initialCapacity];
    } else if (initialCapacity == 0) {
        this.elementData = EMPTY_ELEMENTDATA;
    } else {
        throw new IllegalArgumentException("Illegal Capacity: "+
                                           initialCapacity);
    }
}

When I were trying install librosa package with pip (pip install librosa), this error were appeared:

ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

I tried to remove llvmlite, but pip uninstall could not remove it. So, I used capability of ignore of pip by this code:

pip install librosa --ignore-installed llvmlite

Indeed, you can use this rule for ignoring a package you don't want to consider:

pip install {package you want to install} --ignore-installed {installed package you don't want to consider}

For CodeIgniter 4, you can use the built-in API Response Trait

Here's sample code for reference:

<?php namespace App\Controllers;

use CodeIgniter\API\ResponseTrait;

class Home extends BaseController
{
    use ResponseTrait;

    public function index()
    {
        $data = [
            'data' => 'value1',
            'data2' => 'value2',
        ];

        return $this->respond($data);
    }
}

You can simply use (char) System.in.read(); casting to char is necessary to convert int to char

The config file is just an XML file, you can open it by:

private static XmlDocument loadConfigDocument()
{
    XmlDocument doc = null;
    try
    {
        doc = new XmlDocument();
        doc.Load(getConfigFilePath());
        return doc;
    }
    catch (System.IO.FileNotFoundException e)
    {
        throw new Exception("No configuration file found.", e);
    }
    catch (Exception ex)
    {
        return null;
    }
}

and later retrieving values by:

    // retrieve appSettings node

    XmlNode node =  doc.SelectSingleNode("//appSettings");

This will resolve your issue. Please try it.

$zip = new ZipArchive;
$zip->open('testPDFZip.zip', ZipArchive::CREATE);
foreach (glob(APPLICATION_PATH."pages/recruitment/uploads/test_pdf_folder/*") as $file) {
    $new_filename = end(explode("/",$file));
    $zip->addFile($file,"emp/".$new_filename);
}           
$zip->close();

None of the answers here worked for me. What I had to do is:

1. Re-run the installer.
2. Select the quick action 're-configure' next to product 'MySQL Server'
3. Go through the options till you reach Authentication Method and select 'Use Legacy Authentication Method'

After that it works fine.

The maximum value of an integer (which is signed) is 2147483647. If that value overflows, an exception is thrown to prevent unexpected behavior of your program.

If that exception wouldn't be thrown, you'd have a value of -2145629296 for your Volume, which is most probably not wanted.

Solution: Use an Int64 for your volume. With a max value of 9223372036854775807, you're probably more on the safe side.

Double quote (" ") the entire URL .It works.

curl "http://www.mysite.com?name=john&passwd=@31&3*J"

stage.getIcons().add(new Image(ClassLoader.getSystemResourceAsStream("images/icon.png")));

images folder need to be in Resource folder.

There is now (AutoMapper 2.0) an IgnoreMap attribute, which I'm going to use rather than the fluent syntax which is a bit heavy IMHO.

You might wanna try return new String(byteout.toByteArray(Charset.forName("UTF-8")))

How about FK_TABLENAME_COLUMNNAME?

Keep It Simple Stupid whenever possible.

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.

This is some pseudocodish JavaScript:

Client:

var websocket = new WebSocket("server address");

websocket.onmessage = function(str) {
  console.log("Someone sent: ", str);
};

// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
  id: "client1"
}));

// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
  to: "client2",
  data: "foo"
}));

Server:

var clients = {};

server.on("data", function(client, str) {
  var obj = JSON.parse(str);

  if("id" in obj) {
    // New client, add it to the id/client object
    clients[obj.id] = client;
  } else {
    // Send data to the client requested
    clients[obj.to].send(obj.data);
  }
});

Programmers often confuse multidimensional arrays with arrays of pointers.

Multidimensional arrays

Most programmers are familiar with named multidimensional arrays, but many are unaware of the fact that multidimensional array can also be created anonymously. Multidimensional arrays are often referred to as "arrays of arrays" or "true multidimensional arrays".

Named multidimensional arrays

When using named multidimensional arrays, all dimensions must be known at compile time:

int H = read_int();
int W = read_int();

int connect_four[6][7];   // okay

int connect_four[H][7];   // ISO C++ forbids variable length array
int connect_four[6][W];   // ISO C++ forbids variable length array
int connect_four[H][W];   // ISO C++ forbids variable length array

This is how a named multidimensional array looks like in memory:

              +---+---+---+---+---+---+---+
connect_four: |   |   |   |   |   |   |   |
              +---+---+---+---+---+---+---+
              |   |   |   |   |   |   |   |
              +---+---+---+---+---+---+---+
              |   |   |   |   |   |   |   |
              +---+---+---+---+---+---+---+
              |   |   |   |   |   |   |   |
              +---+---+---+---+---+---+---+
              |   |   |   |   |   |   |   |
              +---+---+---+---+---+---+---+
              |   |   |   |   |   |   |   |
              +---+---+---+---+---+---+---+

Note that 2D grids such as the above are merely helpful visualizations. From the point of view of C++, memory is a "flat" sequence of bytes. The elements of a multidimensional array are stored in row-major order. That is, connect_four[0][6] and connect_four[1][0] are neighbors in memory. In fact, connect_four[0][7] and connect_four[1][0] denote the same element! This means that you can take multi-dimensional arrays and treat them as large, one-dimensional arrays:

int* p = &connect_four[0][0];
int* q = p + 42;
some_int_sequence_algorithm(p, q);

Anonymous multidimensional arrays

With anonymous multidimensional arrays, all dimensions except the first must be known at compile time:

int (*p)[7] = new int[6][7];   // okay
int (*p)[7] = new int[H][7];   // okay

int (*p)[W] = new int[6][W];   // ISO C++ forbids variable length array
int (*p)[W] = new int[H][W];   // ISO C++ forbids variable length array

This is how an anonymous multidimensional array looks like in memory:

              +---+---+---+---+---+---+---+
        +---> |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+
        |     |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+
        |     |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+
        |     |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+
        |     |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+
        |     |   |   |   |   |   |   |   |
        |     +---+---+---+---+---+---+---+
        |
      +-|-+
   p: | | |
      +---+

Note that the array itself is still allocated as a single block in memory.

Arrays of pointers

You can overcome the restriction of fixed width by introducing another level of indirection.

Named arrays of pointers

Here is a named array of five pointers which are initialized with anonymous arrays of different lengths:

int* triangle[5];
for (int i = 0; i < 5; ++i)
{
    triangle[i] = new int[5 - i];
}

// ...

for (int i = 0; i < 5; ++i)
{
    delete[] triangle[i];
}

And here is how it looks like in memory:

          +---+---+---+---+---+
          |   |   |   |   |   |
          +---+---+---+---+---+
            ^
            | +---+---+---+---+
            | |   |   |   |   |
            | +---+---+---+---+
            |   ^
            |   | +---+---+---+
            |   | |   |   |   |
            |   | +---+---+---+
            |   |   ^
            |   |   | +---+---+
            |   |   | |   |   |
            |   |   | +---+---+
            |   |   |   ^
            |   |   |   | +---+
            |   |   |   | |   |
            |   |   |   | +---+
            |   |   |   |   ^
            |   |   |   |   |
            |   |   |   |   |
          +-|-+-|-+-|-+-|-+-|-+
triangle: | | | | | | | | | | |
          +---+---+---+---+---+

Since each line is allocated individually now, viewing 2D arrays as 1D arrays does not work anymore.

Anonymous arrays of pointers

Here is an anonymous array of 5 (or any other number of) pointers which are initialized with anonymous arrays of different lengths:

int n = calculate_five();   // or any other number
int** p = new int*[n];
for (int i = 0; i < n; ++i)
{
    p[i] = new int[n - i];
}

// ...

for (int i = 0; i < n; ++i)
{
    delete[] p[i];
}
delete[] p;   // note the extra delete[] !

And here is how it looks like in memory:

          +---+---+---+---+---+
          |   |   |   |   |   |
          +---+---+---+---+---+
            ^
            | +---+---+---+---+
            | |   |   |   |   |
            | +---+---+---+---+
            |   ^
            |   | +---+---+---+
            |   | |   |   |   |
            |   | +---+---+---+
            |   |   ^
            |   |   | +---+---+
            |   |   | |   |   |
            |   |   | +---+---+
            |   |   |   ^
            |   |   |   | +---+
            |   |   |   | |   |
            |   |   |   | +---+
            |   |   |   |   ^
            |   |   |   |   |
            |   |   |   |   |
          +-|-+-|-+-|-+-|-+-|-+
          | | | | | | | | | | |
          +---+---+---+---+---+
            ^
            |

Conversions

Array-to-pointer decay naturally extends to arrays of arrays and arrays of pointers:

int array_of_arrays[6][7];
int (*pointer_to_array)[7] = array_of_arrays;

int* array_of_pointers[6];
int** pointer_to_pointer = array_of_pointers;

However, there is no implicit conversion from T[h][w] to T**. If such an implicit conversion did exist, the result would be a pointer to the first element of an array of h pointers to T (each pointing to the first element of a line in the original 2D array), but that pointer array does not exist anywhere in memory yet. If you want such a conversion, you must create and fill the required pointer array manually:

int connect_four[6][7];

int** p = new int*[6];
for (int i = 0; i < 6; ++i)
{
    p[i] = connect_four[i];
}

// ...

delete[] p;

Note that this generates a view of the original multidimensional array. If you need a copy instead, you must create extra arrays and copy the data yourself:

int connect_four[6][7];

int** p = new int*[6];
for (int i = 0; i < 6; ++i)
{
    p[i] = new int[7];
    std::copy(connect_four[i], connect_four[i + 1], p[i]);
}

// ...

for (int i = 0; i < 6; ++i)
{
    delete[] p[i];
}
delete[] p;

You're not parsing a string, you're parsing an already-parsed object :)

var obj1 = JSON.parse('{"creditBalance":0,...,"starStatus":false}');
//                    ^                                          ^
//                    if you want to parse, the input should be a string 

var obj2 = {"creditBalance":0,...,"starStatus":false};
// or just use it directly.

1. Set the UIViewControllerBasedStatusBarAppearance to YES in the .plist file.

2. In the viewDidLoad do a [self setNeedsStatusBarAppearanceUpdate];

3. Add the following method:

   - (UIStatusBarStyle)preferredStatusBarStyle
   { 
       return UIStatusBarStyleLightContent; 
   }
   

Note: This does not work for controllers inside UINavigationController, please see Tyson's comment below :)

Swift 3 - This will work controllers inside UINavigationController. Add this code inside your controller.

// Preferred status bar style lightContent to use on dark background.
// Swift 3
override var preferredStatusBarStyle: UIStatusBarStyle {
    return .lightContent
}

Swift 5 and SwiftUI

For SwiftUI create a new swift file called HostingController.swift

import Foundation
import UIKit
import SwiftUI

class HostingController: UIHostingController<ContentView> {
    override var preferredStatusBarStyle: UIStatusBarStyle {
        return .lightContent
    }
}

Then change the following lines of code in the SceneDelegate.swift

window.rootViewController = UIHostingController(rootView: ContentView())

to

window.rootViewController = HostingController(rootView: ContentView())

1. You should install ALL dependencies:

   sudo apt-get install build-essential python3-dev python3-setuptools python3-numpy python3-scipy libatlas-dev libatlas3gf-base

2. Install pip3(if you have installed, please look step 3):

   sudo apt-get install python3-pip

3. Iinstall scikit-learn by pip3

   pip3 install -U scikit-learn

4. Open your terminal and entry python3 environment, type import sklearn to check it.

Gook Luck!

function sleep(num) {
    var now = new Date();
    var stop = now.getTime() + num;
    while(true) {
        now = new Date();
        if(now.getTime() > stop) return;
    }
}

sleep(1000);   // 1 second 
alert('here');

this code work well for me.

The vscode codebase does not use relative paths, but everything works fine for them

Really depends on your module loader. If you are using systemjs with baseurl then it would work. VSCode uses its own custom module loader (based on an old version of requirejs).

Recommendation

Use relative paths as that is what commonjs supports. If you move files around you will get a typescript compile time error (a good thing) so you will be better off than a great majority of pure js projects out there (on npm).

Collapse all : CTRL + SHIFT + /

Expand all code blocks : CTRL + *

Webstorm 11 and 2016.2.3

The least painful and indeed Django-recommended way of doing this is through a OneToOneField(User) property.

Extending the existing User model

…

If you wish to store information related to User, you can use a one-to-one relationship to a model containing the fields for additional information. This one-to-one model is often called a profile model, as it might store non-auth related information about a site user.

That said, extending django.contrib.auth.models.User and supplanting it also works...

Substituting a custom User model

Some kinds of projects may have authentication requirements for which Django’s built-in User model is not always appropriate. For instance, on some sites it makes more sense to use an email address as your identification token instead of a username.

[Ed: Two warnings and a notification follow, mentioning that this is pretty drastic.]

I would definitely stay away from changing the actual User class in your Django source tree and/or copying and altering the auth module.

You can simply use named constructors for creating different types of buttons with icons. For instance

FlatButton.icon(onPressed: null, icon: null, label: null);
RaisedButton.icon(onPressed: null, icon: null, label: null);

But if you have specfic requirements then you can always create custom button with different layouts or simply wrap a widget in GestureDetector.

ConsoleAppLauncher is an open source library made specifically to answer that question. It captures all the output generated in the console and provides simple interface to start and close console application.

The ConsoleOutput event is fired every time when a new line is written by the console to standard/error output. The lines are queued and guaranteed to follow the output order.

Also available as NuGet package.

Sample call to get full console output:

// Run simplest shell command and return its output.
public static string GetWindowsVersion()
{
    return ConsoleApp.Run("cmd", "/c ver").Output.Trim();
}

Sample with live feedback:

// Run ping.exe asynchronously and return roundtrip times back to the caller in a callback
public static void PingUrl(string url, Action<string> replyHandler)
{
    var regex = new Regex("(time=|Average = )(?<time>.*?ms)", RegexOptions.Compiled);
    var app = new ConsoleApp("ping", url);
    app.ConsoleOutput += (o, args) =>
    {
        var match = regex.Match(args.Line);
        if (match.Success)
        {
            var roundtripTime = match.Groups["time"].Value;
            replyHandler(roundtripTime);
        }
    };
    app.Run();
}

You need to catch the return value.

The DateTime.AddDays method returns an object who's value is the sum of the date and time of the instance and the added value.

endDate = endDate.AddDays(addedDays);

When you start the server it mentions this in the startup text.

After removing the innodb_additional_mem_pool_size=4M from my.ini and killing that process that used the port that Mysql wanted I managed it to go.

Suggested fix: 1) The quick solution: Comment the line innodb_additional_mem_pool_size=4M in the service's 'my.ini' file, 2) exclude the option from the 5.7.4 default config file or 3) un-unknow the variable to mysql ;)

link: http://bugs.mysql.com/bug.php?id=72533

Use number 1, remove the whole line. Save to my.ini. Kill the process if you have one running (look at them with resmon.exe and kill them with command taskkill /pid pid-of-process /f), then start wampmysql and your icon should turn green.

Base on this I was able to solve this by changing the constructor of XmlSerializer I was using instead of changing the classes.

Instead of using something like this (suggested in the other answers):

[XmlInclude(typeof(Derived))]
public class Base {}

public class Derived : Base {}

public void Serialize()
{
    TextWriter writer = new StreamWriter(SchedulePath);
    XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>));
    xmlSerializer.Serialize(writer, data);
    writer.Close();
}

I did this:

public class Base {}

public class Derived : Base {}

public void Serialize()
{
    TextWriter writer = new StreamWriter(SchedulePath);
    XmlSerializer xmlSerializer = new XmlSerializer(typeof(List<Derived>), new[] { typeof(Derived) });
    xmlSerializer.Serialize(writer, data);
    writer.Close();
}

Assuming the question is about accessing files in the application folder after the ClickOnce (true == System.Deployment.ApplicationDeploy.IsNetworkDeployed) application is installed on the user's PC, their are three ways to get this folder by the application itself:

String path1 = System.AppDomain.CurrentDomain.BaseDirectory;
String path2 = System.IO.Directory.GetCurrentDirectory();    
String path3 = System.Reflection.Assembly.GetExecutingAssembly().CodeBase; //Remove the last path component, the executing assembly itself.

These work from VS IDE and from a deployed/installed ClickedOnce app, no "true == System.Deployment.ApplicationDeploy.IsNetworkDeployed" check required. ClickOnce picks up any files included in the Visual Studio 2017 project so really the application can access any and all deployed files using relative paths from within the application.

This is based on Windows 10 and Visual Studio 2017

Rebooting the machine worked for me.

$ reboot

As a developer, you should probably start learning set operations (difference, union, intersection). You can imagine your array as one "set", and the keys you are searching for the other.

Check if ALL needles exist

function in_array_all($needles, $haystack) {
   return empty(array_diff($needles, $haystack));
}

echo in_array_all( [3,2,5], [5,8,3,1,2] ); // true, all 3, 2, 5 present
echo in_array_all( [3,2,5,9], [5,8,3,1,2] ); // false, since 9 is not present

Check if ANY of the needles exist

function in_array_any($needles, $haystack) {
   return !empty(array_intersect($needles, $haystack));
}

echo in_array_any( [3,9], [5,8,3,1,2] ); // true, since 3 is present
echo in_array_any( [4,9], [5,8,3,1,2] ); // false, neither 4 nor 9 is present

It's in the app.config file.

<configuration>
  <system.serviceModel>
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceDebug includeExceptionDetailInFaults="true"/>

you can try this,it will work for you

number_format(0.00, 2)

Just declare the variable at the starting of a class.

e.g. for string variable:

public partial class Login : System.Web.UI.Page
{
    public string sError;

    protected void Page_Load(object sender, EventArgs e)
    {
         //Page Load Code
    }

your can try this :

SELECT columnName1, CAST(columnName2 AS  SIGNED ) FROM tableName
