Programs & Examples On #Unresponsive progressbar

Sometimes this error occurs for old javascript sdk. If you save locally javascript file. Update it. I prefer to load it form the facebook server all the time.

Generate the migration file:

rails g migration FixName

# Creates db/migrate/xxxxxxxxxx.rb

Edit the migration to do your will.

class FixName < ActiveRecord::Migration
  def change
    rename_column :table_name, :old_column, :new_column
  end
end

If you have carriage return/line feeds within columns, str_getcsv will not work.

Try https://github.com/synappnz/php-csv

Use:

include "csv.php";
$csv = new csv(file_get_contents("filename.csv"));
$rows = $csv->rows();
foreach ($rows as $row)
{
  // do something with $row
}

It's the part of the .NET Framework that isn't contained within the Client Profile. See MSDN for more info; specifically:

The .NET Framework is made up of the .NET Framework 4 Client Profile and .NET Framework 4 Extended components that exist separately in Programs and Features.

refer johnml1135 answer, but not fully work.

after self investigate, work now:

as official say:

????

????????????????????? /sdcard/Download ???????? API ?????????????,?? API 22,?????:Settings > Device:Storage & USB > Internal Storage > Explore(?? SD ?)?

and use Drag and Drop actually worked, but use android self installed app Download, then you can NOT find the copied file, for not exist so called /sdcard/Download folder.

finally using other file manager app, like

ES File Explorer

then can see the really path is

/storage/emulated/0/Download/

which contains the copied files, like

/storage/emulated/0/Download/chenhongyu_lixiangsanxun.mp3

after drag and drop more mp3 files:

you can use DOM

$(this).children().first()
// is equivalent to
$(this.firstChild)

just do this:

python manage.py runserver 0:8000

by the above command you are actually binding it to the external IP address. so now when you access your IP address with the port number, you will be able to access it in the browser without any problem.

just type in the following in the browser address bar:

<your ip address>:8000

eg:

192.168.1.130:8000

you may have to edit the settings.py add the following in the settings.py in the last line:

ALLOWED_HOSTS = ['*']

hope this will help...

In addition to RMT's answer. I also had to modify the code a bit.

1. Transport.send should be accessed statically
2. therefor, transport.connect did not do anything for me, I only needed to set the connection info in the initial Properties object.

here is my sample send() methods. The config object is just a dumb data container.

public boolean send(String to, String from, String subject, String text) {
    return send(new String[] {to}, from, subject, text);
}

public boolean send(String[] to, String from, String subject, String text) {

    Properties props = new Properties();
    props.put("mail.smtp.auth", "true");
    props.put("mail.smtp.host", config.host);
    props.put("mail.smtp.user", config.username);
    props.put("mail.smtp.port", config.port);
    props.put("mail.smtp.password", config.password);

    Session session = Session.getInstance(props, new SmtpAuthenticator(config));

    try {
        Message message = new MimeMessage(session);
        message.setFrom(new InternetAddress(from));
        InternetAddress[] addressTo = new InternetAddress[to.length];
        for (int i = 0; i < to.length; i++) {
            addressTo[i] = new InternetAddress(to[i]);
        }
        message.setRecipients(Message.RecipientType.TO, addressTo);
        message.setSubject(subject);
        message.setText(text);
        Transport.send(message);
    } catch (MessagingException e) {
        e.printStackTrace();
        return false;
    }
    return true;
}

If it were a completely new row that you wanted to only set one value, you would need to add the whole row and then set the individual value:

DataRow dr = dt.NewRow();
dr[3].Value = "Some Value";
dt.Rows.Add(dr);

Otherwise, you can find the existing row and set the cell value

DataRow dr = dt.Rows[theRowNumber];
dr[3] = "New Value";

Both works. Instead of == you can write eq

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

You can do the following to learn/test the concept:

1. Open new Excel Workbook and in Excel VBA editor right-click on Modules->Insert->Module

2. In newly added Module1 add the declaration; Public Global1 As String

3. in Worksheet VBA Module Sheet1(Sheet1) put the code snippet:

Sub setMe()
      Global1 = "Hello"
End Sub

4. in Worksheet VBA Module Sheet2(Sheet2) put the code snippet:

Sub showMe()
    Debug.Print (Global1)
End Sub

5. Run in sequence Sub setMe() and then Sub showMe() to test the global visibility/accessibility of the var Global1

Hope this will help.

No answer like this:

SELECT * FROM table WHERE something LIKE ('bla% %foo% batz%')

In oracle no problem.

That is not possible without intercepting addEventListener calls and keep track of the listeners or use a library that allows such features unfortunately. It would have been if the listeners collection was accessible but the feature wasn't implemented.

The closest thing you can do is to remove all listeners by cloning the element, which will not clone the listeners collection.

Note: This will also remove listeners on element's children.

var el = document.getElementById('el-id'),
    elClone = el.cloneNode(true);

el.parentNode.replaceChild(elClone, el);

You can't add a class directly to the LIs very easily, but is there any reason not to target them in a slightly different but equally specific way (by their parent ul)?

You can set the class or ID of the menu with the menu_class and menu_id parameters (affixed to the UL parent of the LIs) and then target the li's via CSS that way, like so:

<?php wp_nav_menu('menu_id=mymenu'); ?>

And for CSS:

ul#mymenu li {
    /* your styles here */
}

Edit: At the time of writing in 2013 this was the easiest way to add it, but updates since then have added the feature to add CSS classes directly in the admin navigation editor. See more recent answers for details.

I would also highly recommend Adminer - http://www.adminer.org/

It is much faster than phpMyAdmin, does less funky iframe stuff, and supports both MySQL and PostgreSQL.

The precise wording of the question makes me think it's impossible.

return to me means you have a function, which you have passed a string as a parameter.

You cannot change this parameter. Assigning to it will only change the value of the parameter within the function, not the passed in string. E.g.

>>> def removeAndReturnLastCharacter(a):
        c = a[-1]
        a = a[:-1]
        return c

>>> b = "Hello, Gaukler!"
>>> removeAndReturnLastCharacter(b)
!

>>> b    # b has not been changed
Hello, Gaukler!

I was getting the same error "com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Table 'mylocaldb.hibernate_sequence' doesn't exist".

Using spring mvc 4.3.7 and hibernate version 5.2.9, application is made using spring java based configuration. Now I have to add the hibernate.id.new_generator_mappings property mentioned by @Eva Mariam in my code like this:

@Autowired
    @Bean(name = "sessionFactory")
    public SessionFactory getSessionFactory(DataSource dataSource) {

        LocalSessionFactoryBuilder sessionBuilder = new LocalSessionFactoryBuilder(dataSource);
        sessionBuilder.addProperties(getHibernateProperties());
        sessionBuilder.addAnnotatedClasses(User.class);

        return sessionBuilder.buildSessionFactory();
    }

    private Properties getHibernateProperties() {
        Properties properties = new Properties();
        properties.put("hibernate.show_sql", "true");
        properties.put("hibernate.dialect", "org.hibernate.dialect.MySQLDialect");
        properties.put("hibernate.id.new_generator_mappings","false");
        return properties;
    }

And it worked like charm.

The answer is to DISABLE "Enable auto-completion on each input". Tested and works perfectly.

He want an elegant and proper solution try this small regex pattern matcher.

This is specifically for India.(First digit can't be zero and and then can be any 9 digits) return mobile.matches("[1-9][0-9]{9}");

Pattern Breakdown:-

[1-9] matches first digit and checks if number(integer) lies between(inclusive) 1 to 9 [0-9]{9} matches the same thing but {9} tells the pattern that it has to check for upcoming all 9 digits.

Now the {9} part may vary for different countries so you may have array which tells the number of digits allowed in phone number. Some countries also have significance for zero ahead of number, so you may have exception for those and design a separate regex patterns for those countries phone numbers.

I know the topic was asked some time ago, but recently I had faced similar issue and found yet another, but in my opinion a more complete solution. I decided to implement mechanism which provides conditional attributes to calculate validation results based on other properties values and relations between them, which are defined in logical expressions.

Using it you are able to achieve the result you asked about in the following manner:

[RequiredIf("MyProperty2 == null && MyProperty3 == false")]
public string MyProperty1 { get; set; }

[RequiredIf("MyProperty1 == null && MyProperty3 == false")]
public string MyProperty2 { get; set; }

[AssertThat("MyProperty1 != null || MyProperty2 != null || MyProperty3 == true")]
public bool MyProperty3 { get; set; }

More information about ExpressiveAnnotations library can be found here. It should simplify many declarative validation cases without the necessity of writing additional case-specific attributes or using imperative way of validation inside controllers.

You should read it recursively, some time ago I had the same question and solve with this code:

public void proccessMenuNodeList(NodeList nl, JMenuBar menubar) {
    for (int i = 0; i < nl.getLength(); i++) {
        proccessMenuNode(nl.item(i), menubar);
    }
}

public void proccessMenuNode(Node n, Container parent) {
    if(!n.getNodeName().equals("menu"))
        return;
    Element element = (Element) n;
    String type = element.getAttribute("type");
    String name = element.getAttribute("name");
    if (type.equals("menu")) {
        NodeList nl = element.getChildNodes();
        JMenu menu = new JMenu(name);

        for (int i = 0; i < nl.getLength(); i++)
            proccessMenuNode(nl.item(i), menu);

        parent.add(menu);
    } else if (type.equals("item")) {
        JMenuItem item = new JMenuItem(name);
        parent.add(item);
    }
}

Probably you can adapt it for your case.

Try this:

<td>
    <a onclick="return confirm(\'Are you sure?\');" href="'.base_url('category/delete_category/'.$row->category_id).'" class="btn btn-danger btn-sm"><i class="fa fa-trash"></i> Delete Coupon</a>
</td>

I Hope that this helps you out... Because I tried all the answers but nothing worked perfectly. So, I had to come up with a solution on my own.

#horizontal-style {
  padding-inline-start: 0 !important; // Just in case if you find that there is an extra padding at the start of the line 
  justify-content: space-around;
  display: flex;
}

#horizontal-style a {
    text-align: center;
    color: white;
    text-decoration: none;
}

Angular deprecated $cookieStore in version 1.4.x, so use $cookies instead if you are using latest version of angular. Syntax remain same for $cookieStore & $cookies:

$cookies.put("key", "value"); 
var value = $cookies.get("key");

See the Docs for an API overview. Mind also that the cookie service has been enhanced with some new important features like setting expiration (see this answer) and domain (see CookiesProvider Docs).

Note that, in version 1.3.x or below, $cookies has a different syntax than above:

$cookies.key = "value";
var value = $cookies.value; 

Also if you are using bower, make sure to type your package name correctly:

bower install [email protected] 

where X.Y.Z is the AngularJS version you are running. There's another package in bower "angular-cookie"(without the 's') which is not the official angular package.

We have come across this issue in desktop app.

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);
  }
});

The transforms are SVG transforms (for details, have a look at the standard; here are some examples). Basically, scale and translate apply the respective transformations to the coordinate system, which should work as expected in most cases. You can apply more than one transform however (e.g. first scale and then translate) and then the result might not be what you expect.

When working with the transforms, keep in mind that they transform the coordinate system. In principle, what you say is true -- if you apply a scale > 1 to an object, it will look bigger and a translate will move it to a different position relative to the other objects.

The answers from Tomik and Peterdk work when you want your custom view to occupy the entire action bar, even hiding the native title.

But if you want your custom view to live side-by-side with the title (and fill all remaining space after the title is displayed), then may I refer you to the excellent answer from user Android-Developer here:

https://stackoverflow.com/a/16517395/614880

His code at bottom worked perfectly for me.

If I have this directory:

ls -l

drwxr-xr-x  2 nagios nagios   4096 août  23 16:36 tmp

To get all directories, use -L to resolve links:

ls -lL | grep '^d'

drwxr-xr-x 2 nagios nagios   4096 août  23 16:41 tmp

Without -L:

ls -l | grep '^d'

drwxr-xr-x 2 nagios nagios   4096 août  23 16:41 tmp

conf_nagios directory is missing.

There are a few ways you can define constants in Kotlin,

Using companion object

    companion object {
        const val ITEM1 = "item1"
        const val ITEM2 = "item2"
    }

you can use above companion object block inside any class and define all your fields inside this block itself. But there is a problem with this approach, the documentation says,

even though the members of companion objects look like static members in other languages, at runtime those are still instance members of real objects, and can, for example, implement interfaces.

When you create your constants using companion object, and see the decompiled bytecode, you'll something like below,

  ClassName.Companion Companion = ClassName.Companion.$$INSTANCE;
  @NotNull
  String ITEM1 = "item1";
  @NotNull
  String ITEM2 = "item2";

  public static final class Companion {
     @NotNull
     private static final String ITEM1 = "item1";
     @NotNull
     public static final String ITEM2 = "item2";

     // $FF: synthetic field
     static final ClassName.Companion $$INSTANCE;

     private Companion() {
     }

     static {
        ClassName.Companion var0 = new ClassName.Companion();
        $$INSTANCE = var0;
     }
  }

From here you can easily see what the documentation said, even though the members of companion objects look like static members in other languages, at runtime those are still instance members of real objects It's doing extra work than required.

Now comes another way, where we don't need to use companion object like below,

object ApiConstants {
      val ITEM1: String = "item1"
 }

Again if you see the decompiled version of the byte code of above snippet, you'll find something like this,

public final class ApiConstants {
     private static final String ITEM1 = "item1";

     public static final ApiConstants INSTANCE;

     public final String getITEM1() {
           return ITEM1;
      }

     private ApiConstants() {
      }

     static {
         ApiConstants var0 = new ApiConstants();
         INSTANCE = var0;
         CONNECT_TIMEOUT = "item1";
      }
    }

Now if you see the above decompiled code, it's creating get method for each variable. This get method is not required at all.

To get rid of these get methods, you should use const before val like below,

object ApiConstants {
     const val ITEM1: String = "item1"
 }

Now if you see the decompiled code of above snippet, you'll find it easier to read as it does the least background conversion for your code.

public final class ApiConstants {
    public static final String ITEM1 = "item1";
    public static final ApiConstants INSTANCE;

    private ApiConstants() {
     }

    static {
        ApiConstants var0 = new ApiConstants();
        INSTANCE = var0;
      }
    }

So this is the best way to create constants.

The most common valid reason for wanting an integer constant associated with each enum value is to interoperate with some other component which still expects those integers (e.g. a serialization protocol which you can't change, or the enums represent columns in a table, etc).

In almost all cases I suggest using an EnumMap instead. It decouples the components more completely, if that was the concern, or if the enums represent column indices or something similar, you can easily make changes later on (or even at runtime if need be).

 private final EnumMap<Page, Integer> pageIndexes = new EnumMap<Page, Integer>(Page.class);
 pageIndexes.put(Page.SIGN_CREATE, 1);
 //etc., ...

 int createIndex = pageIndexes.get(Page.SIGN_CREATE);

It's typically incredibly efficient, too.

Adding data like this to the enum instance itself can be very powerful, but is more often than not abused.

Edit: Just realized Bloch addressed this in Effective Java / 2nd edition, in Item 33: Use EnumMap instead of ordinal indexing.

Assigning questionFrame.frame.size.height= screenSize.height * 0.30 will not reflect anything in the view. because it is a get-only property. If you want to change the frame of questionFrame you can use the below code.

questionFrame.frame = CGRect(x: 0, y: 0, width: 0, height: screenSize.height * 0.70)

Either install the supplementary packages for python-ssl using your package manager or recompile Python using -with-ssl (requires OpenSSL headers/libs installed).

I fixed the issue (temporarily) by going to Edit Scheme, then in the Build section, removing my unit test target from being invoked in "Run".

Do this instead:

values = [[1,2,3],[4,5]]
for x in values:
    if len(x) == 3:
       print(x)

I've got a similar error when installing FCL that needs CCD lib(libccd) like this:

/usr/bin/ld: /usr/local/lib/libccd.a(ccd.o): relocation R_X86_64_32S against `a local symbol' can not be used when making a shared object; recompile with -fPIC

I find that there is two different files named "libccd.a" :

1. /usr/local/lib/libccd.a
2. /usr/local/lib/x86_64-linux-gnu/libccd.a

I solved the problem by removing the first file.

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

:) Your using the thread in a wrong way. Just do the following:

private void runthread()
{

splashTread = new Thread() {
            @Override
            public void run() {
                try {
                    synchronized(this){

                        //wait 5 sec
                        wait(_splashTime);
                    }

                } catch(InterruptedException e) {}
                finally {
                    //call the handler to set the text
                }
            }
        };

        splashTread.start(); 
}

That's it.

I ran into the same problem, I was pulling an iframe into a div. Try this:

<iframe src="http://stackoverflow.com/" frameborder="0" scrolling="yes" seamless="seamless" style="display:block; width:100%; height:100vh;"></iframe>

The height is set to 100vh which stands for viewport height. Also, the width could be set to 100vw, although you'll likely run into problems if the source file is responsive (your frame will become very wide).

Create a new datafile by running the following command:

alter tablespace TABLE_SPACE_NAME add datafile 'D:\oracle\Oradata\TEMP04.dbf'            
   size 2000M autoextend on;

The first one is the "short" form - you use it, when you do not want to do something fancy with your getters and setters. It is not possible to execute a method or something like that in this form.

The second and third form are almost identical, albeit the second one is compressed to one line. This form is discouraged by stylecop because it looks somewhat weird and does not conform to C' Stylguides.

I would use the third form if I expectd to use my getters / setters for something special, e.g. use a lazy construct or so.

By reading online (tables tutorial) it seems tables behave like arrays so you're looking for:

Way1

names = {'John', 'Joe', 'Steve'}
for i = 1,3 do print( names[i] ) end

Way2

names = {'John', 'Joe', 'Steve'}
for k,v in pairs(names) do print(v) end

Way1 uses the table index/key , on your table names each element has a key starting from 1, for example:

names = {'John', 'Joe', 'Steve'}
print( names[1] ) -- prints John

So you just make i go from 1 to 3.

On Way2 instead you specify what table you want to run and assign a variable for its key and value for example:

names = {'John', 'Joe', myKey="myValue" }
for k,v in pairs(names) do print(k,v) end

prints the following:

1   John

Assuming all models are in app/models and you have grep & awk on your server (majority of the cases),

# extract lines that match specific string, and print 2nd word of each line
results = `grep -r "< ActiveRecord::Base" app/models/ | awk '{print $2}'`
model_names = results.split("\n")

It it faster than Rails.application.eager_load! or looping through each file with Dir.

EDIT:

The disadvantage of this method is that it misses models that indirectly inherit from ActiveRecord (e.g. FictionalBook < Book). The surest way is Rails.application.eager_load!; ActiveRecord::Base.descendants.map(&:name), even though it's kinda slow.

var attr = $(this).attr('name');

// For some browsers, `attr` is undefined; for others,
// `attr` is false.  Check for both.
if (typeof attr !== typeof undefined && attr !== false) {
    // ...
}

You can try like this :

input[placeholder] {
   text-align: center;
}

There is the rather obscure, and soon to be deprecated, feature called ticks. The only thing I have ever used it for, is to allow a script to capture SIGKILL (Ctrl+C) and close down gracefully.

I would rewrite your dequeue function as:

std::string FileQueue::dequeue(const std::chrono::milliseconds& timeout)
{
    std::unique_lock<std::mutex> lock(qMutex);
    while(q.empty()) {
        if (populatedNotifier.wait_for(lock, timeout) == std::cv_status::timeout ) 
           return std::string();
    }
    std::string ret = q.front();
    q.pop();
    return ret;
}

It is shorter and does not have duplicate code like your did. Only issue it may wait longer that timeout. To prevent that you would need to remember start time before loop, check for timeout and adjust wait time accordingly. Or specify absolute time on wait condition.

When you are done with using your Connection, you need to explicitly close it by calling its close() method in order to release any other database resources (cursors, handles, etc.) the connection may be holding on to.

Actually, the safe pattern in Java is to close your ResultSet, Statement, and Connection (in that order) in a finally block when you are done with them. Something like this:

Connection conn = null;
PreparedStatement ps = null;
ResultSet rs = null;

try {
    // Do stuff
    ...

} catch (SQLException ex) {
    // Exception handling stuff
    ...
} finally {
    if (rs != null) {
        try {
            rs.close();
        } catch (SQLException e) { /* Ignored */}
    }
    if (ps != null) {
        try {
            ps.close();
        } catch (SQLException e) { /* Ignored */}
    }
    if (conn != null) {
        try {
            conn.close();
        } catch (SQLException e) { /* Ignored */}
    }
}

The finally block can be slightly improved into (to avoid the null check):

} finally {
    try { rs.close(); } catch (Exception e) { /* Ignored */ }
    try { ps.close(); } catch (Exception e) { /* Ignored */ }
    try { conn.close(); } catch (Exception e) { /* Ignored */ }
}

But, still, this is extremely verbose so you generally end up using an helper class to close the objects in null-safe helper methods and the finally block becomes something like this:

} finally {
    DbUtils.closeQuietly(rs);
    DbUtils.closeQuietly(ps);
    DbUtils.closeQuietly(conn);
}

And, actually, the Apache Commons DbUtils has a DbUtils class which is precisely doing that, so there isn't any need to write your own.

Firstly to create a Component you need to use:-

• ng g c componentname

  By using above command New Component will be created in a folder with
  (componentname) you specified above.

But if you need to create a component inside of another component or in specific folder:-

• ng g c componentname/newComponentName

Recursion gets a bad rep, I'm always surprised by the number of developers that wont even touch recursion because someone told them it was evil incarnate.

I've learned through trial and error that when done properly recursion can be one of the fastest ways to iterate over something, it is not a steadfast rule and each language/ compiler/ engine has it's own quirks so mileage will vary.

In javascript I can reliably speed up almost any iterative process by introducing recursion with the added benefit of reducing side effects and making the code more clear concise and reusable. Also pro tip its possible to get around the stack overflow issue (and no you dont disable the warning).

My personal Pros & Cons:

Pros:

- Reduces side effects.
- Makes code more concise and easier to reason about.
- Reduces system resource usage and performs better than the traditional for loop.

Cons:

- Can lead to stack overflow.
- More complicated to setup than a traditional for loop.

Mileage will vary depending on language/ complier/ engine.

' '   

space was missing in my case, when a blank space added ' \r\n' started to work

Direct value should work just fine:

var sv = sel.value;
alert(sv);

The only reason your code might fail is when there is no item selected, then the selectedIndex returns -1 and the code breaks.

The benefits of super() in single-inheritance are minimal -- mostly, you don't have to hard-code the name of the base class into every method that uses its parent methods.

However, it's almost impossible to use multiple-inheritance without super(). This includes common idioms like mixins, interfaces, abstract classes, etc. This extends to code that later extends yours. If somebody later wanted to write a class that extended Child and a mixin, their code would not work properly.

• You can use copy con to write a long text

• Example:

  C:\COPY CON [drive:][path][File name]

  .... Content

  F6

  1 file(s) is copied

What? In your validation function, just put

document.onlyform.upload.value="";

Assuming upload is the name:

<input type="file" name="upload" id="csv_doc"/>

I'm using JSP, not sure if that makes a difference...

Works for me, and I think it's way easier.

In the nav go View => Layout => Columns:2 (alt+shift+2) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py)

It appears you can also reopen the file using the command File -> New View into File which will open the current file in a new tab

Not at all. Lambda expressions are the one and only point of that annotation.

Or Joiner from Google Guava.

Joiner joiner = Joiner.on("+");
String join = joiner.join(joinList);

Update queueAll() method as below:

public Cursor queueAll() {

     String selectQuery = "SELECT * FROM " + MYDATABASE_TABLE;
     Cursor cursor = sqLiteDatabase.rawQuery(selectQuery, null);

     return cursor;
}

Update readFileFromSQLite() method as below:

public ArrayList<String> readFileFromSQLite() {

    fileName = new ArrayList<String>();

    fileSQLiteAdapter = new FileSQLiteAdapter(FileChooser.this);
    fileSQLiteAdapter.openToRead();

    cursor = fileSQLiteAdapter.queueAll();

    if (cursor != null) {
        if (cursor.moveToFirst()) {
            do 
            {
                String name = cursor.getString(cursor.getColumnIndex(FileSQLiteAdapter.KEY_CONTENT1));
                fileName.add(name);
            } while (cursor.moveToNext());
        }
        cursor.close();
    }

    fileSQLiteAdapter.close();

    return fileName;
}

I tend to do this (if I really, really had to):

for i in some_var:
   if type(i) == type(list()):
       #do something with a list
   elif type(i) == type(tuple()):
       #do something with a tuple
   elif type(i) == type(str()):
       #here's your string

Why is that not acceptable?

document.getElementById('test').innerHTML += str

would be the textbook way of doing it.

Whenever one has a dictionary where the values are integers, the Counter data structure is often a better choice to represent the data than a dictionary.

If you already have a dictionary, a counter can easily be formed by:

c = Counter(d['123'])

as an example from your data.

The most_common function allows easy access to descending order of the items in the counter

The more complete writeup on the Counter data structure is at https://docs.python.org/2/library/collections.html

There is a close() function for InfoWindows. Just keep track of the last opened window, and call the close function on it when a new window is created.

Starting from Spring Boot version 1.2.0.RELEASE , there is a property you can add to your application.properties to set a default date format to all of your classes spring.jackson.date-format.

For your date format example, you would add this line to your properties file:

spring.jackson.date-format=yyyy-MM-dd

Reference https://docs.spring.io/spring-boot/docs/1.2.0.RELEASE/reference/html/common-application-properties.html

First - why is that an EXEC? Shouldn't that just be

AS
SELECT Column_Name, ...
FROM ...
WHERE TABLE_NAME = @template

The current SP doesn't make sense? In particular, that would look for a column matching @template, not the varchar value of @template. i.e. if @template is 'Column_Name', it would search WHERE TABLE_NAME = Column_Name, which is very rare (to have table and column named the same).

Also, if you do have to use dynamic SQL, you should use EXEC sp_ExecuteSQL (keeping the values as parameters) to prevent from injection attacks (rather than concatenation of input). But it isn't necessary in this case.

Re the actual problem - it looks OK from a glance; are you sure you don't have a different copy of the SP hanging around? This is a common error...

When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[]
For example:
if your radio button is:

<input type="radio" name="rdb" value="male"/>

then in your php code you need to use:

$rdb_value = $_POST['rdb'];

I was just going through this myself. I had ensured that my MSSQLSERVER login user had full access but it was still causing issues. It only worked once I moved the destination to the root of C. More importantly out of a user folder (even though I had a share with full permissions - even tried "Everyone" as a test).

I don't know if i consider my issue "fixed", however it is "working".

Just a FYI for any other users that come across this thread.

Based on luttken's answer. Thought I'd add my twist :)

function dateIsInBetween(\DateTime $from, \DateTime $to, \DateTime $subject)
{
    return $subject->getTimestamp() > $from->getTimestamp() && $subject->getTimestamp() < $to->getTimestamp() ? true : false;
}

$paymentDate       = new \DateTime('now');
$contractDateBegin = new \DateTime('01/01/2001');
$contractDateEnd   = new \DateTime('01/01/2016');

echo dateIsInBetween($contractDateBegin, $contractDateEnd, $paymentDate) ? "is between" : "NO GO!";

I think with np.array() you can only create C like though you mention the order, when you check using np.isfortran() it says false. but with np.ndarrray() when you specify the order it creates based on the order provided.

Maybe this code helps:

var chunk_size = 10;_x000D_
var arr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17];_x000D_
var groups = arr.map( function(e,i){ _x000D_
     return i%chunk_size===0 ? arr.slice(i,i+chunk_size) : null; _x000D_
}).filter(function(e){ return e; });_x000D_
console.log({arr, groups})

sometimes you need to set Padding, not Margin to make space between items smaller than default

corona is nice. From the tutorial:

corona::Image* image = corona::OpenImage("img.jpg", corona::PF_R8G8B8A8);
if (!image) {
  // error!
}

int width  = image->getWidth();
int height = image->getHeight();
void* pixels = image->getPixels();

// we're guaranteed that the first eight bits of every pixel is red,
// the next eight bits is green, and so on...
typedef unsigned char byte;
byte* p = (byte*)pixels;
for (int i = 0; i < width * height; ++i) {
  byte red   = *p++;
  byte green = *p++;
  byte blue  = *p++;
  byte alpha = *p++;
}

pixels would be a one dimensional array, but you could easily convert a given x and y position to a position in a 1D array. Something like pos = (y * width) + x

It's as simple as this :

$array[$key];

Standard Python dictionaries are inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = dic.values()[index]

Bear in mind that adding or removing an element can potentially change the index of every other element.

re install your java. First check your OS version.

Being a void element, an <input> element is considered empty by the HTML definition of "empty", since the content model of all void elements is always empty. So they will always match the :empty pseudo-class, whether or not they have a value. This is also why their value is represented by an attribute in the start tag, rather than text content within start and end tags.

Also, from the Selectors spec:

The :empty pseudo-class represents an element that has no children at all. In terms of the document tree, only element nodes and content nodes (such as DOM text nodes, CDATA nodes, and entity references) whose data has a non-zero length must be considered as affecting emptiness;

Consequently, input:not(:empty) will never match anything in a proper HTML document. (It would still work in a hypothetical XML document that defines an <input> element that can accept text or child elements.)

I don't think you can style empty <input> fields dynamically using just CSS (i.e. rules that apply whenever a field is empty, and don't once text is entered). You can select initially empty fields if they have an empty value attribute (input[value=""]) or lack the attribute altogether (input:not([value])), but that's about it.

A minimal in-python solution that colors json data supplied via the command line:

import sys
import json
from pygments import highlight, lexers, formatters

formatted_json = json.dumps(json.loads(sys.argv[1]), indent=4)
colorful_json = highlight(unicode(formatted_json, 'UTF-8'), lexers.JsonLexer(), formatters.TerminalFormatter())
print(colorful_json)

Inspired by pjson mentioned above. This code needs pygments to be installed.

Output example:

One way I have gotten around this is by create a static class for instances. I used it a lot in AS3 I has worked great for me in android development too.

Config.java

public final class Config {
    public static MyApp context = null;
}

MyApp.java

public class MyApp extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Config.context = this;
    }
    ...
}

You can then access the context or by using Config.context

LocationManager locationManager;
String context = Context.LOCATION_SERVICE;
locationManager = Config.context.getSystemService(context);

window.location.href = window.location.href

on delete button click event

public void delete(View v){                

    ListView listview1;
    ArrayList<E> datalist;

    final int position = listview1.getPositionForView((View) v.getParent());
    datalist.remove(position);
    myAdapter.notifyDataSetChanged();

}

This error happens when the branch you are switching to, has changes that your current branch doesn't have.

If you are seeing this error when you try to switch to a new branch, then your current branch is probably behind one or more commits. If so, run:

git fetch

You should also remove dependencies which may also conflict with the destination branch.

For example, for iOS developers:

pod deintegrate

then try checking out a branch again.

If the desired branch isn't new you can either cherry pick a commit and fix the conflicts or stash the changes and then fix the conflicts.

1. Git Stash (recommended)

git stash
git checkout <desiredBranch>
git stash apply

2. Cherry pick (more work)

git add <your file>
git commit -m "Your message"
git log

Copy the sha of your commit. Then discard unwanted changes:

git checkout .
git checkout -- . 
git clean -f -fd -fx

Make sure your branch is up to date:

git fetch

Then checkout to the desired branch

git checkout <desiredBranch>

Then cherry pick the other commit:

git cherry-pick <theSha>

Now fix the conflict.

3. Otherwise, your other option is to abandon your current branches changes with:

git checkout -f branch

System.Data.SQLite has a dependency on System.Data.SQLite.interop make sure both packages are the same version and are both x86.

This is an old question, but I tried all the above. I was working on a strictly x86 project, so there was not two folders /x86, /x64. But for some reason, the System.Data.SQLite was a different version to System.Data.SQLite.interop, once I pulled down matching dlls the problem was fixed.

try this

   SELECT group_name, employees, surveys, COUNT( surveys ) AS test1, 
        concat(round(( surveys/employees * 100 ),2),'%') AS percentage
    FROM a_test
    GROUP BY employees

DEMO HERE

You can try the following snippet:

 var str = "How,are,you,doing,today?";
    var res = str.split(",");
    console.log("My Result:", res)

yeah I have same experience

The ADB is now located in the platform-tools directory.

1. korsosa said Check your [sdk directory]/platform-tools directory, if it exists. If not, then open the SDK manager in the Android Studio (a button somewhere in the top menu, android logo with a down arrow), and download&install the Tools > Android SDK Platform-tools.

2. If you have platform-tools, you have check adb.exe file. In my case, that file was broken, so download that platform-tools again

Unity <= 2019

Narottam Goyal had a good idea of wrapping the array in a json object, and then deserializing into a struct. The following uses Generics to solve this for arrays of all type, as opposed to making a new class everytime.

[System.Serializable]
private struct JsonArrayWrapper<T> {
    public T wrap_result;
}

public static T ParseJsonArray<T>(string json) {
    var temp = JsonUtility.FromJson<JsonArrayWrapper<T>>("{\" wrap_result\":" + json + "}");
    return temp.wrap_result;
}

It can be used in the following way:

string[] options = ParseJsonArray<string[]>(someArrayOfStringsJson);

Unity 2020

In Unity 2020 there is an official newtonsoft package which is a far better json library.

This went a little weird for me, from one day to the next one the script that have been working since days just stop working. There wasn´t a newer version of mysql or any kind of upgrade but I was getting the same error, so I give a last try to the CSV file and notice that the end of lines were using \n instead of the expected ( per my script ) \r\n so I save it with the right EOL and run the script again without any trouble.

I think is kind of odd for mysql to tell me The used command is not allowed with this MySQL version since the reason was completely different.

My working command looks like this:

LOAD DATA LOCAL INFILE 'file-name' IGNORE INTO TABLE table-name CHARACTER SET latin1 FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 LINES.

Also note, if you just want to see the changed files between the last commit and the one before it. This works fine: git show --name-only

On many devices (such as the iPhone), it prevents the user from using the browser's zoom. If you have a map and the browser does the zooming, then the user will see a big ol' pixelated image with huge pixelated labels. The idea is that the user should use the zooming provided by Google Maps. Not sure about any interaction with your plugin, but that's what it's there for.

More recently, as @ehfeng notes in his answer, Chrome for Android (and perhaps others) have taken advantage of the fact that there's no native browser zooming on pages with a viewport tag set like that. This allows them to get rid of the dreaded 300ms delay on touch events that the browser takes to wait and see if your single touch will end up being a double touch. (Think "single click" and "double click".) However, when this question was originally asked (in 2011), this wasn't true in any mobile browser. It's just added awesomeness that fortuitously arose more recently.

Smart pointers will clean themselves up after they go out of scope (thereby removing fear of most memory leaks). Shared pointers are smart pointers that keep a count of how many instances of the pointer exist, and only clean up the memory when the count reaches zero. In general, only use shared pointers (but be sure to use the correct kind--there is a different one for arrays). They have a lot to do with RAII.

You can also do this with hooks.

function MyComponent (props) {
  const [isActive, setActive] = useState(false);

  const toggleClass = () => {
    setActive(!isActive);
  };

  return (
    <div 
      className={isActive ? 'your_className': null} 
      onClick={toggleClass} 
    >
      <p>{props.text}</p>
    </div>
   );
}  

The bug you reference (bug 4787391) has been fixed in Java 8. Even if you are using an older version of Java, the System.getProperty("user.home") approach is probably still the best. The user.home approach seems to work in a very large number of cases. A 100% bulletproof solution on Windows is hard, because Windows has a shifting concept of what the home directory means.

If user.home isn't good enough for you I would suggest choosing a definition of home directory for windows and using it, getting the appropriate environment variable with System.getenv(String).

There could be two ways/syntax to bind a static property. If p is a static property in class MainWindow, then binding for textbox will be:

1.

<TextBox Text="{x:Static local:MainWindow.p}" />

2.

<TextBox Text="{Binding Source={x:Static local:MainWindow.p},Mode=OneTime}" />

You can increase the capacity of the stack by the following :

import sys
sys.setrecursionlimit(10000)

In addition to placeholder="your text" you could also do onclick="this.value='';

So it would look something like:

<input name="Name" value="Enter Your Name" onclick="this.value='';>

Another solution is to use AngularJS. The AngularUI module has a directive called ng-grid which supports a feature called column pinning. It is not 100% pure CSS but neither are the other solutions.

http://angular-ui.github.io/ng-grid/#columnPinning

Alternativly if your using bootstrap then you can just add align-middle to vertical align the element.

<button id="whaever" class="btn btn-large btn-primary" style="padding: 20px;" name="Continue" type="submit">Continue
    <i class="icon-ok align-middle" style="font-size:40px;"></i>
</button>

you can just use

ls > filenames.txt

(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd to go to that folder first, or you can ls ~/docs > filenames.txt

PHP FILE

<?php
$target_path  = "./Upload/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ".  basename( $_FILES['uploadedfile']['name']).

Two files: 1) An app.config or web.config file. The settings her can be customized after build with a text editer. 2) The settings.designer.cs file. This file has autogenerated code to load the setting from the config file, but a default value is also present in case the config file does not have the particular setting.

You can try this if you are passing a value to the action method.

@Html.DropDownList("Sortby", new SelectListItem[] { new SelectListItem() { Text = "Newest to Oldest", Value = "0" }, new SelectListItem() { Text = "Oldest to Newest", Value = "1" }},new { onchange = "document.location.href = '/ControllerName/ActionName?id=' + this.options[this.selectedIndex].value;" })

Remove the query string in case of no parameter passing.

It's != without type coercion. See the MDN documentation for comparison operators.

Also see this StackOverflow answer, which includes a quote from "JavaScript: The Good Parts" about the problems with == and !=. (null == undefined, false == "0", etc.)

Short answer: always use === and !== unless you have a compelling reason to do otherwise. (Tools like JSLint, JSHint, ESLint, etc. will give you this same advice.)

I got much better solution .

here is my directive , I have injected on object reference in directive and has extend that by adding invoke function in directive code .

app.directive('myDirective', function () {
    return {
        restrict: 'E',
        scope: {
        /*The object that passed from the cntroller*/
        objectToInject: '=',
        },
        templateUrl: 'templates/myTemplate.html',

        link: function ($scope, element, attrs) {
            /*This method will be called whet the 'objectToInject' value is changes*/
            $scope.$watch('objectToInject', function (value) {
                /*Checking if the given value is not undefined*/
                if(value){
                $scope.Obj = value;
                    /*Injecting the Method*/
                    $scope.Obj.invoke = function(){
                        //Do something
                    }
                }    
            });
        }
    };
});

Declaring the directive in the HTML with a parameter:

<my-directive object-to-inject="injectedObject"></ my-directive>

my Controller:

app.controller("myController", ['$scope', function ($scope) {
   // object must be empty initialize,so it can be appended
    $scope.injectedObject = {};

    // now i can directly calling invoke function from here 
     $scope.injectedObject.invoke();
}];

I believe that the best idea is just to capture in a group whatever you want to replace, and then replace it by using the start and end properties of the captured group.

regards

Adrián

#the pattern will contain the expression we want to replace as the first group
pat = "word1\s(.*)\sword2"   
test = "word1 will never be a word2"
repl = "replace"

import re
m = re.search(pat,test)

if m and m.groups() > 0:
    line = test[:m.start(1)] + repl + test[m.end(1):]
    print line
else:
    print "the pattern didn't capture any text"

This will print: 'word1 will never be a word2'

The group to be replaced could be located in any position of the string.

Use this System.Web.Hosting.HostingEnvironment.MapPath().

HostingEnvironment.MapPath("~/file")

Wonder why nobody mentioned it here.

To completely remove the ul default style:

    list-style-type: none;

    margin: 0;
    margin-block-start: 0;
    margin-block-end: 0;
    margin-inline-start: 0;
    margin-inline-end: 0;
    padding-inline-start: 0;

The following line is looking for the exact NavigableString 'Python':

>>> soup.body.findAll(text='Python')
[]

Note that the following NavigableString is found:

>>> soup.body.findAll(text='Python Jobs') 
[u'Python Jobs']

Note this behaviour:

>>> import re
>>> soup.body.findAll(text=re.compile('^Python$'))
[]

So your regexp is looking for an occurrence of 'Python' not the exact match to the NavigableString 'Python'.

You can use javascript to access elements on the page and modify their contents. So for example you might have a page with some HTML markup like so:

<div id="MyEdit">
    This text will change
</div>

You can use javascript to change the content like so...

document.getElementById("MyEdit").innerHTML = "My new text!";?

Here is a working example

You can also look at using the JQuery javascript library for DOM manipulation, it has some great features to make things like this very easy.

For example, with JQuery, you could do this to acheive the same result...

$("#MyEdit").html("My new text!");

Here is a working example of the JQuery version

Based on this example you provided in your post. The following JQuery would work for you:

var x = "hello wolrd";
$("p").html(x);

Here is the working version

Using a P tag like this however is not recommended. You would ideally want to use an element with a unique ID so you can ensure you are selecting the correct one with JQuery.

I was having the same problem. It seems that passing Me.ComboBox1.Value as an argument for the Vlookup function is causing the issue. What I did was assign this value to a double and then put it into the Vlookup function.

Dim x As Double
x = Me.ComboBox1.Value
Me.TextBox1.Value = Application.WorksheetFunction.VLookup(x, Worksheets("Sheet3").Range("Names"), 2, False) 

Or, for a shorter method, you can just convert the type within the Vlookup function using Cdbl(<Value>).

So it would end up being

Me.TextBox1.Value = Application.WorksheetFunction.VLookup(Cdbl(Me.ComboBox1.Value), Worksheets("Sheet3").Range("Names"), 2, False) 

Strange as it may sound, it works for me.

Hope this helps.

Add the options which have been provided so far won't use your indexes at all.

Something like this will do the trick, and make use of an index on the table (if one exists).

DECLARE @StartDate DATETIME, @EndDate DATETIME
SET @StartDate = dateadd(mm, -1, getdate())
SET @StartDate = dateadd(dd, datepart(dd, getdate())*-1, @StartDate)
SET @EndDate = dateadd(mm, 1, @StartDate)

SELECT *
FROM Member
WHERE date_created BETWEEN @StartDate AND @EndDate

dbo is the default schema in SQL Server. You can create your own schemas to allow you to better manage your object namespace.

Another way of doing this is using nested IF statements. Suppose you have companies table and you want to count number of records in it. A sample query would be something like this

SELECT IF(
      count(*) > 15,
      'good',
      IF(
          count(*) > 10,
          'average',
          'poor'
        ) 
      ) as data_count 
      FROM companies

Here second IF condition works when the first IF condition fails. So Sample Syntax of the IF statement would be IF ( CONDITION, THEN, ELSE). Hope it helps someone.

Change your select box options value:

<select id="cmbMake" name="Make" >
     <option value="">Select Manufacturer</option>
     <option value="Any">--Any--</option>
     <option value="Toyota">Toyota</option>
     <option value="Nissan">Nissan</option>
  </select>

You cann't get the text of selected option in php. it will give only the value of selected option.

EDITED:

<select id="cmbMake" name="Make" >
     <option value="0">Select Manufacturer</option>
     <option value="1_Any">--Any--</option>
     <option value="2_Toyota">Toyota</option>
     <option value="3_Nissan">Nissan</option>
  </select>

ON php file:

$maker = mysql_real_escape_string($_POST['Make']);
$maker = explode("_",$maker);
echo $maker[1]; //give the Toyota
echo $maker[0]; //give the key 2

Images have display: inline by default.
You might want to put the image inside the paragraph.
<p><img /></p>

Those files are created and used by Android Studio editor.

You don't need to check in those files to version control.

Git uses .gitignore file, that contains list of files and directories, to know the list of files and directories that don't need to be checked in.

Android studio automatically creates .gitingnore files listing all files and directories which don't need to be checked in to any version control.

The easiest way to solve this problem and enable the functionality of readlink on Mac w/ Homebrew installed or FreeBSD is to install 'coreutils' package. May also be necessary on certain Linux distributions and other POSIX OS.

For example, in FreeBSD 11, I installed by invoking:

# pkg install coreutils

On MacOS with Homebrew, the command would be:

$ brew install coreutils

Not really sure why the other answers are so complicated, that's all there is to it. The files aren't in a different place, they're just not installed yet.

Perhaps this complementary example of "match" would be helpful.

Having two datasets:

first_dataset <- data.frame(name = c("John", "Luke", "Simon", "Gregory", "Mary"),
                            role = c("Audit", "HR", "Accountant", "Mechanic", "Engineer"))

second_dataset <- data.frame(name = c("Mary", "Gregory", "Luke", "Simon"))

If the name column contains only unique across collection values (across whole collection) then you can access row in other dataset by value of index returned by match

name_mapping <- match(second_dataset$name, first_dataset$name)

match returns proper row indexes of names in first_dataset from given names from second: 5 4 2 1 example here - accesing roles from first dataset by row index (by given name value)

for(i in 1:length(name_mapping)) {
    role <- as.character(first_dataset$role[name_mapping[i]])   
    second_dataset$role[i] = role
}

===

second dataset with new column:
     name       role
1    Mary   Engineer
2 Gregory   Mechanic
3    Luke Supervisor
4   Simon Accountant

When using the formal protocol method for creating delegate support, I've found that you can ensure proper type checking (albeit, runtime, not compile time) by adding something like:

if (![delegate conformsToProtocol:@protocol(MyDelegate)]) {
    [NSException raise:@"MyDelegate Exception"
                format:@"Parameter does not conform to MyDelegate protocol at line %d", (int)__LINE__];
}

in your delegate accessor (setDelegate) code. This helps minimize mistakes.

1. Locate the file at /etc/mysql/my.cnf

2. Edit the file by adding the following lines:

    [mysqld]
   
    lower_case_table_names=1
   

3. sudo /etc/init.d/mysql restart

4. Run mysqladmin -u root -p variables | grep table to check that lower_case_table_names is 1 now

You might need to recreate these tables to make it work.

For posterity / completeness's sake… Here are two FULL examples of how to implement this ridiculously versatile "way of doing things". @Robert's answer is blissfully concise and correct, but here I want to also show ways to actually "define" the blocks.

@interface       ReusableClass : NSObject
@property (nonatomic,copy) CALayer*(^layerFromArray)(NSArray*);
@end

@implementation  ResusableClass
static  NSString const * privateScope = @"Touch my monkey.";

- (CALayer*(^)(NSArray*)) layerFromArray { 
     return ^CALayer*(NSArray* array){
        CALayer *returnLayer = CALayer.layer
        for (id thing in array) {
            [returnLayer doSomethingCrazy];
            [returnLayer setValue:privateScope
                         forKey:@"anticsAndShenanigans"];
        }
        return list;
    };
}
@end

Silly? Yes. Useful? Hells yeah. Here is a different, "more atomic" way of setting the property.. and a class that is ridiculously useful…

@interface      CALayoutDelegator : NSObject
@property (nonatomic,strong) void(^layoutBlock)(CALayer*);
@end

@implementation CALayoutDelegator
- (id) init { 
   return self = super.init ? 
         [self setLayoutBlock: ^(CALayer*layer){
          for (CALayer* sub in layer.sublayers)
            [sub someDefaultLayoutRoutine];
         }], self : nil;
}
- (void) layoutSublayersOfLayer:(CALayer*)layer {
   self.layoutBlock ? self.layoutBlock(layer) : nil;
}   
@end

This illustrates setting the block property via the accessor (albeit inside init, a debatably dicey practice..) vs the first example's "nonatomic" "getter" mechanism. In either case… the "hardcoded" implementations can always be overwritten, per instance.. a lá..

CALayoutDelegator *littleHelper = CALayoutDelegator.new;
littleHelper.layoutBlock = ^(CALayer*layer){
  [layer.sublayers do:^(id sub){ [sub somethingElseEntirely]; }];
};
someLayer.layoutManager = littleHelper;

Also.. if you want to add a block property in a category... say you want to use a Block instead of some old-school target / action "action"... You can just use associated values to, well.. associate the blocks.

typedef    void(^NSControlActionBlock)(NSControl*); 
@interface       NSControl            (ActionBlocks)
@property (copy) NSControlActionBlock  actionBlock;    @end
@implementation  NSControl            (ActionBlocks)

- (NSControlActionBlock) actionBlock { 
    // use the "getter" method's selector to store/retrieve the block!
    return  objc_getAssociatedObject(self, _cmd); 
} 
- (void) setActionBlock:(NSControlActionBlock)ab {

    objc_setAssociatedObject( // save (copy) the block associatively, as categories can't synthesize Ivars.
    self, @selector(actionBlock),ab ,OBJC_ASSOCIATION_COPY);
    self.target = self;                  // set self as target (where you call the block)
    self.action = @selector(doItYourself); // this is where it's called.
}
- (void) doItYourself {

    if (self.actionBlock && self.target == self) self.actionBlock(self);
}
@end

Now, when you make a button, you don't have to set up some IBAction drama.. Just associate the work to be done at creation...

_button.actionBlock = ^(NSControl*thisButton){ 

     [doc open]; [thisButton setEnabled:NO]; 
};

This pattern can be applied OVER and OVER to Cocoa API's. Use properties to bring the relevant parts of your code closer together, eliminate convoluted delegation paradigms, and leverage the power of objects beyond that of just acting as dumb "containers".

The CLR uses it when it is compiling at runtime. Here is a link to MSDN that explains further.

For reloading the page for a given route path :-

$location.path('/path1/path2');
$route.reload();

I realized the solution to this problem stems from Eclipse memory allocation when you run the application in normal mode. I just checked the "Run as Administrator" box under the shortcut properties for Eclipse and now it allows me to allocate more memory for the AVD.

Hope that helps.

I totally agree with Abacus (sorry - don't have enough points to comment).

Also, keep in mind it doesn't necessarily come down to how many records you have, but the size of your records.

For instance, have you considered the performance difference between 1,000 records with 50 columns each vs 100,000 records with only 5 columns each?

Lastly, maybe you're querying/storing more data than you need? Here's a good read on SQL optimization strategies. Limit the amount of data you're pulling, especially if you're not using it all (some SQL programmers do get lazy and just select everything even though they only use a tiny subset). Don't forget the SQL query analyzer may also become your best friend.

You can use React.cloneElement, it's better to know how it works before you start using it in your application. It's introduced in React v0.13, read on for more information, so something along with this work for you:

<div>{React.cloneElement(this.props.children, {...this.props})}</div>

So bring the lines from React documentation for you to understand how it's all working and how you can make use of them:

In React v0.13 RC2 we will introduce a new API, similar to React.addons.cloneWithProps, with this signature:

React.cloneElement(element, props, ...children);

Unlike cloneWithProps, this new function does not have any magic built-in behavior for merging style and className for the same reason we don't have that feature from transferPropsTo. Nobody is sure what exactly the complete list of magic things are, which makes it difficult to reason about the code and difficult to reuse when style has a different signature (e.g. in the upcoming React Native).

React.cloneElement is almost equivalent to:

<element.type {...element.props} {...props}>{children}</element.type>

However, unlike JSX and cloneWithProps, it also preserves refs. This means that if you get a child with a ref on it, you won't accidentally steal it from your ancestor. You will get the same ref attached to your new element.

One common pattern is to map over your children and add a new prop. There were many issues reported about cloneWithProps losing the ref, making it harder to reason about your code. Now following the same pattern with cloneElement will work as expected. For example:

var newChildren = React.Children.map(this.props.children, function(child) {
  return React.cloneElement(child, { foo: true })
});

Note: React.cloneElement(child, { ref: 'newRef' }) DOES override the ref so it is still not possible for two parents to have a ref to the same child, unless you use callback-refs.

This was a critical feature to get into React 0.13 since props are now immutable. The upgrade path is often to clone the element, but by doing so you might lose the ref. Therefore, we needed a nicer upgrade path here. As we were upgrading callsites at Facebook we realized that we needed this method. We got the same feedback from the community. Therefore we decided to make another RC before the final release to make sure we get this in.

We plan to eventually deprecate React.addons.cloneWithProps. We're not doing it yet, but this is a good opportunity to start thinking about your own uses and consider using React.cloneElement instead. We'll be sure to ship a release with deprecation notices before we actually remove it so no immediate action is necessary.

You can also do this in ASP.NET Core 2 by defining the connection string in your appSettings.json file. Then in your Startup.cs you specify which connection string to use.

appSettings.json

{
    "connectionStrings": {
        "YourDBConnectionString": "Server=(localdb)\\mssqllocaldb;Database=YourDB;Trusted_Connection=True"
    }
}

Startup.cs

public static IConfiguration Configuration { get; private set;}

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

Another place I've seen this error is when your project has multiple targets AND multiple bridging headers. If it's a shared class, make sure you add the resource to all bridging headers.

A good tip to is to look in the left Issue Navigator panel; the root object will show the target that is issuing the complaint.

The following expression should be unbiased if I am not mistaken:

std::floor( ( max - min + 1.0 ) * rand() ) + min;

I am assuming here that rand() gives you a random value in the range between 0.0 and 1.0 NOT including 1.0 and that max and min are integers with the condition that min < max.

Or if you want a simple one-liner:

Person person = JAXB.unmarshal(new StringReader("<?xml ..."), Person.class);

A probable cause could be that you do not pass the command line parameters into the applications main method. I made the same mistake some weeks ago.

public static final void main(String... args) {
    SpringApplication.run(Application.class, args);
}

You could try this

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),FALSE, TRUE)

-or-

=IF(ISNA(VLOOKUP(<single column I value>,<entire column E range>,1,FALSE)),"FALSE", "File found in row "   & MATCH(<single column I value>,<entire column E range>,0))

you could replace <single column I value> and <entire column E range> with named ranged. That'd probably be the easiest.

Just drag that formula all the way down the length of your I column in whatever column you want.

Silver Searcher is a terrific tool, but ripgrep may be even better.

It works on Linux, Mac and Windows, and was written up on Hacker News a couple of months ago (this has a link to Andrew Gallant's Blog which has a GitHub link):

My fix for this was my child table needed to be populated before the parent table.

I had two tables: UserDetails and Login linked by an email address. I therefore had to insert into the UserDetails first before inserting into the Login table:

insert into UserDetails (Email, Name, Telephone, Department) values ('Email', 'Name', 'number', 'IT');

Then:

insert into Login (UserID, UserType, Email, Username, Password) VALUES (001, 'SYS-USR-ADMIN', 'Email', 'Name', 'Password')

document.getElementById("tblBlah").rows[i].columns[j].innerHTML;

Should be:

document.getElementById("tblBlah").rows[i].cells[j].innerHTML;

But I get the distinct impression that the row/cell you need is the one clicked by the user. If so, the simplest way to achieve this would be attaching an event to the cells in your table:

function alertInnerHTML(e)
{
    e = e || window.event;//IE
    alert(this.innerHTML);
}

var theTbl = document.getElementById('tblBlah');
for(var i=0;i<theTbl.length;i++)
{
    for(var j=0;j<theTbl.rows[i].cells.length;j++)
    {
        theTbl.rows[i].cells[j].onclick = alertInnerHTML;
    }
}

That makes all table cells clickable, and alert it's innerHTML. The event object will be passed to the alertInnerHTML function, in which the this object will be a reference to the cell that was clicked. The event object offers you tons of neat tricks on how you want the click event to behave if, say, there's a link in the cell that was clicked, but I suggest checking the MDN and MSDN (for the window.event object)

This worked for me for cardView and will work the same for listview inside adapter calss, within onBindViewHolder() function

holder.cardView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                return false;
            }
        });

Problem solved after restarting the tomcat and apache, the tomcat was caching older version of the app.

JavaScript only simple solution

datePickerId.max = new Date().toISOString().split("T")[0];

<input type="date" id="datePickerId" />

The simple way to do that in Angular 7+ is to:

Define a path in your ?-routing.module.ts

{ path: '/yourpage', component: component-name }

Import the ActivateRoute and Router module in your component and inject them in the constructor

contructor(private route: ActivateRoute, private router: Router){ ... }

Subscribe the ActivateRoute to the ngOnInit

ngOnInit() {

    this.route.queryParams.subscribe(params => {
      console.log(params);
      // {page: '2' }
    })
}

Provide it to a link:

<a [routerLink]="['/yourpage']" [queryParams]="{ page: 2 }">2</a>

Try the DrawEllipse method instead.

On the subject of ugly hacks, you can always use a combination of exec and a regular function to define a multiline function like this:

f = exec('''
def mlambda(x, y):
    d = y - x
    return d * d
''', globals()) or mlambda

You can wrap this into a function like:

def mlambda(signature, *lines):
    exec_vars = {}
    exec('def mlambda' + signature + ':\n' + '\n'.join('\t' + line for line in lines), exec_vars)
    return exec_vars['mlambda']

f = mlambda('(x, y)',
            'd = y - x',
            'return d * d')

If you set the trunc flag.

#include<fstream>

using namespace std;

fstream ofs;

int main(){
ofs.open("test.txt", ios::out | ios::trunc);
ofs<<"Your content here";
ofs.close(); //Using microsoft incremental linker version 14
}

I tested this thouroughly for my own needs in a common programming situation I had. Definitely be sure to preform the ".close();" operation. If you don't do this there is no telling whether or not you you trunc or just app to the begging of the file. Depending on the file type you might just append over the file which depending on your needs may not fullfill its purpose. Be sure to call ".close();" explicity on the fstream you are trying to replace.

http://maps.google.com/maps?q=58%2041.881N%20152%2031.324W

Just use the coordinates as q-parameter. Strip the z and t prameters. While z should actually just be the zoom level, it seems that it won't work if you set any.

t is the map type. Having that said, it's not obvious how those parameters would affect the result in the shown way. But they do.

Maybe you should try the ll-parameter, but only decimal format will be accepted.

You can find a quick overview of all the parameters here.

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

It can be done via https and oauth or ssh.

https and oauth: create an access token that has "repo" scope and then use this syntax:

"package-name": "git+https://<github_token>:[email protected]/<user>/<repo>.git"

or

ssh: setup ssh and then use this syntax:

"package-name": "git+ssh://[email protected]:<user>/<repo>.git"

(note the use of colon instead of slash before user)

One more solution REPLACE (CHAR(current date, ISO),'-','')

for php 7.0 on ubuntu use

sudo apt-get install php7.0-curl

And finally,

sudo service apache2 restart 

or

sudo service nginx restart

krtek's method has some wrong,I tested this

var startDay = 0; 
var weekStart = new Date(today.getDate() - (7 + today.getDay() - startDay) % 7);
var weekEnd = new Date(today.getDate() + (6 - today.getDay() - startDay) % 7);

it works

Even if it is really discouraged to use merge cells in Excel (use Center Across Selection for instance if needed), the cell that "contains" the value is the one on the top left (at least, that's a way to express it).

Hence, you can get the value of merged cells in range B4:B11 in several ways:

• Range("B4").Value
• Range("B4:B11").Cells(1).Value
• Range("B4:B11").Cells(1,1).Value

You can also note that all the other cells have no value in them. While debugging, you can see that the value is empty.

Also note that Range("B4:B11").Value won't work (raises an execution error number 13 if you try to Debug.Print it) because it returns an array.

Perhaps you can use the built-in methods for finding particular items in an Array, instead of each-ing targets and doing everything by hand. A few examples:

class Array
  def first_frog
    detect {|i| i =~ /frog/ }
  end

  def last_frog
    select {|i| i =~ /frog/ }.last
  end
end

p ["dog", "cat", "godzilla", "dogfrog", "woot", "catfrog"].first_frog
# => "dogfrog"
p ["hats", "coats"].first_frog
# => nil
p ["houses", "frogcars", "bottles", "superfrogs"].last_frog
# => "superfrogs"

One example would be doing something like this:

class Bar
  def do_things
    Foo.some_method(x) do |i|
      # only valid `targets` here, yay.
    end
  end
end

class Foo
  def self.failed
    @failed ||= []
  end

  def self.some_method(targets, &block)
    targets.reject {|t| t.do_something.bad? }.each(&block)
  end
end

Copy-pasted from here: Incrementing a date in JavaScript

Three options for you:

Using just JavaScript's Date object (no libraries):

var today = new Date();
var tomorrow = new Date(today.getTime() + (24 * 60 * 60 * 1000));

Or if you don't mind changing the date in place (rather than creating a new date):

var dt = new Date();
dt.setTime(dt.getTime() + (24 * 60 * 60 * 1000));

Edit: See also Jigar's answer and David's comment below: var tomorrow = new Date(); tomorrow.setDate(tomorrow.getDate() + 1);

Using MomentJS:

var today = moment();
var tomorrow = moment(today).add(1, 'days');

(Beware that add modifies the instance you call it on, rather than returning a new instance, so today.add(1, 'days') would modify today. That's why we start with a cloning op on var tomorrow = ....)

Using DateJS, but it hasn't been updated in a long time:

var today = new Date(); // Or Date.today()
var tomorrow = today.add(1).day();

The answer is YES, but shouldn't use 'Background Fetch' or 'Remote notification'. PushKit is the answer you desire.

In summary, PushKit, the new framework in ios 8, is the new push notification mechanism which can silently launch your app into the background with no visual alert prompt even your app was killed by swiping out from app switcher, amazingly you even cannot see it from app switcher.

PushKit reference from Apple:

The PushKit framework provides the classes for your iOS apps to receive pushes from remote servers. Pushes can be of one of two types: standard and VoIP. Standard pushes can deliver notifications just as in previous versions of iOS. VoIP pushes provide additional functionality on top of the standard push that is needed to VoIP apps to perform on-demand processing of the push before displaying a notification to the user.

To deploy this new feature, please refer to this tutorial: https://zeropush.com/guide/guide-to-pushkit-and-voip - I've tested it on my device and it works as expected.

HERE is another open source library on GitHub named EvalEx.

Unlike the JavaScript engine this library is focused in evaluating mathematical expressions only. Moreover, the library is extensible and supports use of boolean operators as well as parentheses.

Linux Kernel Development by Robert Love (Chapter 12, page 244 in 3rd edition) answers this very clearly.

Yes, physically contiguous memory is not required in many of the cases. Main reason for kmalloc being used more than vmalloc in kernel is performance. The book explains, when big memory chunks are allocated using vmalloc, kernel has to map the physically non-contiguous chunks (pages) into a single contiguous virtual memory region. Since the memory is virtually contiguous and physically non-contiguous, several virtual-to-physical address mappings will have to be added to the page table. And in the worst case, there will be (size of buffer/page size) number of mappings added to the page table.

This also adds pressure on TLB (the cache entries storing recent virtual to physical address mappings) when accessing this buffer. This can lead to thrashing.

You are correct in your understanding of the DOM based model. The XML file will be loaded as a whole and all its contents will be built as an in-memory representation of the tree the document represents. This can be time- and memory-consuming, depending on how large the input file is. The benefit of this approach is that you can easily query any part of the document, and freely manipulate all the nodes in the tree.

The DOM approach is typically used for small XML structures (where small depends on how much horsepower and memory your platform has) that may need to be modified and queried in different ways once they have been loaded.

SAX on the other hand is designed to handle XML input of virtually any size. Instead of the XML framework doing the hard work for you in figuring out the structure of the document and preparing potentially lots of objects for all the nodes, attributes etc., SAX completely leaves that to you.

What it basically does is read the input from the top and invoke callback methods you provide when certain "events" occur. An event might be hitting an opening tag, an attribute in the tag, finding text inside an element or coming across an end-tag.

SAX stubbornly reads the input and tells you what it sees in this fashion. It is up to you to maintain all state-information you require. Usually this means you will build up some sort of state-machine.

While this approach to XML processing is a lot more tedious, it can be very powerful, too. Imagine you want to just extract the titles of news articles from a blog feed. If you read this XML using DOM it would load all the article contents, all the images etc. that are contained in the XML into memory, even though you are not even interested in it.

With SAX you can just check if the element name is (e. g.) "title" whenever your "startTag" event method is called. If so, you know that you needs to add whatever the next "elementText" event offers you. When you receive the "endTag" event call, you check again if this is the closing element of the "title". After that, you just ignore all further elements, until either the input ends, or another "startTag" with a name of "title" comes along. And so on...

You could read through megabytes and megabytes of XML this way, just extracting the tiny amount of data you need.

The negative side of this approach is of course, that you need to do a lot more book-keeping yourself, depending on what data you need to extract and how complicated the XML structure is. Furthermore, you naturally cannot modify the structure of the XML tree, because you never have it in hand as a whole.

So in general, SAX is suitable for combing through potentially large amounts of data you receive with a specific "query" in mind, but need not modify, while DOM is more aimed at giving you full flexibility in changing structure and contents, at the expense of higher resource demand.

You can use Google S2 Converter.

The above answer by pl_rock is correct, the only thing I would add is to expect the ARG inside the Dockerfile if not you won't have access to it. So if you are doing

docker build -t essearch/ess-elasticsearch:1.7.6 --build-arg number_of_shards=5 --build-arg number_of_replicas=2 --no-cache .

Then inside the Dockerfile you should add

ARG number_of_replicas
ARG number_of_shards

I was running into this problem, so I hope I help someone (myself) in the future.

Precision and scale are often misunderstood. In numeric(3,2) you want 3 digits overall, but 2 to the right of the decimal. If you want 15 => 15.00 so the leading 1 causes the overflow (since if you want 2 digits to the right of the decimal, there is only room on the left for one more digit). With 4,2 there is no problem because all 4 digits fit.

Turing-completeness is not only about "defining functions" or "have ifs/loops/etc". For example, Haskell doesn't have "loop", lambda-calculus don't have "ifs", etc...

For example, this site: http://experthuman.com/programming-with-nothing. The author uses Ruby and create a "FizzBuzz" program with only closures (no strings, numbers, or anything like that)...

There are examples when people compute some arithmetical functions on Scala using only the type system

So, yes, in my opinion, CSS3+HTML is turing-complete (even if you can't exactly do any real computation with then without becoming crazy)

If you have the connectivity between servers it is better to set up replication (which is trivial, unlike with SQL) with the new instance as a slave node - then you can switch the new node to master with a single command and do the move with zero downtime.

As discussed, there are several ways to search:

/pattern
?pattern
* (and g*, which I sometimes use in macros)
# (and g#)

plus, navigating prev/next with N and n.

You can also edit/recall your search history by pulling up the search prompt with / and then cycle with C-p/C-n. Even more useful is q/, which takes you to a window where you can navigate the search history.

Also for consideration is the all-important 'hlsearch' (type :hls to enable). This makes it much easier to find multiple instances of your pattern. You might even want make your matches extra bright with something like:

hi Search ctermfg=yellow ctermbg=red guifg=...

But then you might go crazy with constant yellow matches all over your screen. So you’ll often find yourself using :noh. This is so common that a mapping is in order:

nmap <leader>z :noh<CR>

I easily remember this one as z since I used to constantly type /zz<CR> (which is a fast-to-type uncommon occurrence) to clear my highlighting. But the :noh mapping is way better.

I just needed a simple testing button for react.js. Here is what I did and it worked.

function Testing(){
 var f=function testing(){
         console.log("Testing Mode activated");
         UserData.authenticated=true;
         UserData.userId='123';
       };
 console.log("Testing Mode");

 return (<div><button onClick={f}>testing</button></div>);
}

The above solutions like run a query

SET session wait_timeout=600;

Will only work until mysql is restarted. For a persistant solution, edit mysql.conf and add after [mysqld]:

wait_timeout=300
interactive_timeout = 300

Where 300 is the number of seconds you want.

Try to make the bounds's size integer.

#include <math.h>
....

    if (ratio > 1) {
        bounds.size.width = resolution;
        bounds.size.height = round(bounds.size.width / ratio);
    } else {
        bounds.size.height = resolution;
        bounds.size.width = round(bounds.size.height * ratio);
    }

You create handler in background thread this way

private void createHandler() {
        Thread thread = new Thread() {
          public void run() {
               Looper.prepare();

               final Handler handler = new Handler();
               handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                       // Do Work
                        handler.removeCallbacks(this);
                        Looper.myLooper().quit();
                   }
                }, 2000);

                Looper.loop();
            }
        };
        thread.start();
    }

Closing the solution completely and rerunning the project solved my issue.

The mouseenter event differs from mouseover in the way it handles event bubbling. The mouseenter event, only triggers its handler when the mouse enters the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseenter/

The mouseleave event differs from mouseout in the way it handles event bubbling. The mouseleave event, only triggers its handler when the mouse leaves the element it is bound to, not a descendant. Refer: https://api.jquery.com/mouseleave/

As of Ansible 2.0 there seems to be an option called strategy on a playbook. When setting the strategy to free, the playbook plays tasks on each host without waiting to the others. See http://docs.ansible.com/ansible/playbooks_strategies.html.

It looks something like this (taken from the above link):

- hosts: all
  strategy: free
  tasks:
  ...

Please note that I didn't check this and I'm very new to Ansible. I was just curious about doing what you described and happened to come acroess this strategy thing.

EDIT:

It seems like this is not exactly what you're trying to do. Maybe "async tasks" is more appropriate as described here: http://docs.ansible.com/ansible/playbooks_async.html.

This includes specifying async and poll on a task. The following is taken from the 2nd link I mentioned:

- name: simulate long running op, allow to run for 45 sec, fire and forget
  command: /bin/sleep 15
  async: 45
  poll: 0

I guess you can specify longer async times if your task is lengthy. You can probably define your three concurrent task this way.

Without the update-and-join notation (not all DBMS support that), use:

UPDATE QuestionTrackings
   SET QuestionID = (SELECT QuestionID
                        FROM AnswerTrackings
                        WHERE AnswerTrackings.AnswerID = QuestionTrackings.AnswerID)
   WHERE QuestionID IS NULL
     AND EXISTS(SELECT QuestionID
                        FROM AnswerTrackings
                        WHERE AnswerTrackings.AnswerID = QuestionTrackings.AnswerID)

Often in a query like this, you need to qualify the WHERE clause with an EXISTS clause that contains the sub-query. This prevents the UPDATE from trampling over rows where there is no match (usually nulling all the values). In this case, since a missing question ID would change the NULL to NULL, it arguably doesn't matter.

Event::listen('illuminate.query', function($sql, $param)
{
    \Log::info($sql . ", with[" . join(',', $param) ."]<br>\n");
});

put it in global.php it will log your sql query.

To me it is about 2 different meanings of symbol =:

1. In math x = sin(t) means, that x is different name for sin(t). So writing x + y is the same thing as sin(t) + y. Functional reactive programming is like math in this respect: if you write x + y, it is computed with whatever the value of t is at the time it's used.
2. In C-like programming languages (imperative languages), x = sin(t) is an assignment: it means that x stores the value of sin(t) taken at the time of the assignment.

For startswith, you can use indexOf:

if(str.indexOf('Hello') == 0) {

...

ref

and you can do the maths based on string length to determine 'endswith'.

if(str.lastIndexOf('Hello') == str.length - 'Hello'.length) {

I believe Selenium now uses Key.TAB instead of Keys.TAB.

If you truly want set behavior (I'm going by Java knowledge), then you will be hard pressed to find a solution in JavaScript. Most developers will recommend a unique key to represent each object, but this is unlike set, in that you can get two identical objects each with a unique key. The Java API does the work of checking for duplicate values by comparing hash code values, not keys, and since there is no hash code value representation of objects in JavaScript, it becomes almost impossible to do the same. Even the Prototype JS library admits this shortcoming, when it says:

"Hash can be thought of as an associative array, binding unique keys to values (which are not necessarily unique)..."

Try this:

delete from your_table;    
delete from sqlite_sequence where name='your_table';

SQLite Autoincrement

SQLite keeps track of the largest ROWID that a table has ever held using the special SQLITE_SEQUENCE table. The SQLITE_SEQUENCE table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.

1. Look at the exact error

My code worked fine on all machines but only on this one started giving problem (which used to work find I guess). Used echo "document_root" path to debug and also looked closely at the error, found this

Warning: include(D:/MyProjects/testproject//functions/connections.php): failed to open stream:

You can easily see where the problems are. The problems are // before functions

$document_root = $_SERVER['DOCUMENT_ROOT'];
echo "root: $document_root";
include($document_root.'/functions/connections.php');

So simply remove the lading / from include and it should work fine. What is interesting is this behaviors is different on different versions. I run the same code on Laptop, Macbook Pro and this PC, all worked fine untill. Hope this helps someone.

Route::post('/new-order', 'Api\OrderController@initiateOrder')->name('newOrder');

and from the client app I was posting the request to:

https://my-domain/api/new-order/

So, because of the trailing slash I got a 405. Hope it helps someone

If you have ReSharper installed clicking Shift+Alt+L will move focus to the current file in Solution Explorer.

Active Item Tracking will also need to be enabled as described in the accepted answer

Tools->Options->Projects and Solutions->Track Active Item in Solution Explorer

Board.setPreferredSize(new Dimension(x, y));
.
.
//Main.add(Board, BorderLayout.CENTER);
Main.add(Board, BorderLayout.CENTER);
Main.setLocations(x, y);
Main.pack();
Main.setVisible(true);

Step by step localize Info.plist:

1. Find in the Xcode the folder Resources (is placed in root)
2. Select the folder Resources
3. Then press the main menu File->New->File...
4. Select in section "Resource" Strings File and press Next
5. Then in Save As field write InfoPlist ONLY ("I" capital and "P" capital)
6. Then press Create
7. Then select the file InfoPlist.strings that created in Resources folder and press in the right menu the button "Localize"
8. Then you Select the Project from the Project Navigator and select the The project from project list
9. In the info tab at the bottom you can as many as language you want (There is in section Localizations)
10. The language you can see in Resources Folder
11. To localize the values ("key") from info.plist file you can open with a text editor and get all the keys you want to localize
12. You write any key as the example in any InfoPlist.strings like the above example

"NSLocationAlwaysAndWhenInUseUsageDescription"="blabla";

"NSLocationAlwaysUsageDescription"="blabla2";

That's all work and you have localize your info.plist file!

I think you're looking for sys.path

import sys
print (sys.path)

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));

Copy and paste to clipboard in Windows (Cygwin):

See:

$ clip.exe -?

CLIP
Description:
    Redirects output of command line tools to the Windows clipboard.
    This text output can then be pasted into other programs.
Parameter List:
/?                  Displays this help message.
Examples:
DIR | CLIP          Places a copy of the current directory
                        listing into the Windows clipboard.
CLIP < README.TXT   Places a copy of the text from readme.txt
                        on to the Windows clipboard.

Also getclip (it can be used instead of Shift + Ins!) and putclip (echo oaeuoa | putclip.exe to put it into clip) exist.
