Below is a list of the common key codes for quick reference, taken from Events.h.

If you need to use these keycodes in an application, you should include the Carbon framework:

Objective-C:
#include <Carbon/Carbon.h>

Swift:
import Carbon.HIToolbox

You can then use the kVK_ANSI_A constants directly.

WARNING

The key constants reference physical keys on the keyboard. Their output changes if the typist is using a different keyboard layout. The letters in the constants correspond only to the U.S. QWERTY keyboard layout.

For example, the left ring-finger key on the homerow:

QWERTY keyboard layout > s > kVK_ANSI_S > "s"
Dvorak keyboard layout > o > kVK_ANSI_S > "o"

Strategies for layout-agnostic conversion of keycode to string, and vice versa, are discussed here:

From Events.h:

/*
 *  Summary:
 *    Virtual keycodes
 *  
 *  Discussion:
 *    These constants are the virtual keycodes defined originally in
 *    Inside Mac Volume V, pg. V-191. They identify physical keys on a
 *    keyboard. Those constants with "ANSI" in the name are labeled
 *    according to the key position on an ANSI-standard US keyboard.
 *    For example, kVK_ANSI_A indicates the virtual keycode for the key
 *    with the letter 'A' in the US keyboard layout. Other keyboard
 *    layouts may have the 'A' key label on a different physical key;
 *    in this case, pressing 'A' will generate a different virtual
 *    keycode.

Macintosh Toolbox Essentials illustrates the physical locations of these virtual key codes for the Apple Extended Keyboard II in Figure 2-10:

This would be in addition to previous, if someone meets a problem with scandic letters that isn't solved with the solution above.

If the java source files contain scandic letters they need to be interpreted correctly by the Java used for compiling. (e.g. scandic letters used in constants)

Even that the files are stored in UTF-8 and the Maven is configured to use UTF-8, the System Java used by the Maven will still use the system default (eg. in Windows: cp1252).

This will be visible only running the tests via maven (possibly printing the values of these constants in tests. The printed scandic letters would show as '< ?>') If not tested properly, this would corrupt the class files as compile result and be left unnoticed.

To prevent this, you have to set the Java used for compiling to use UTF-8 encoding. It is not enough to have the encoding settings in the maven pom.xml, you need to set the environment variable: JAVA_TOOL_OPTIONS = -Dfile.encoding=UTF8

Also, if using Eclipse in Windows, you may need to set the encoding used in addition to this (if you run individual test via eclipse).

ConcurrentHashMap uses finer-grained locking mechanism known as lock stripping to allow greater degree of shared access. Due to this it provides better concurrency and scalability.

Also iterators returned for ConcurrentHashMap are weakly consistent instead of fail fast technique used by Synchronized HashMap.

DXGI Desktop Capture

Project that captures the desktop image with DXGI duplication. Saves the captured image to the file in different image formats (*.bmp; *.jpg; *.tif).

This sample is written in C++. You also need some experience with DirectX (D3D11, D2D1).

What the Application Can Do

• If you have more than one desktop monitor, you can choose.
• Resize the captured desktop image.
• Choose different scaling modes.
• You can show or hide the mouse icon in the output image.
• You can rotate the image for the output picture, or leave it as default.

Use CONCAT_WS().

SELECT CONCAT_WS(' ',firstname,lastname) as firstlast FROM users 
WHERE firstlast = "Bob Michael Jones";

The first argument is the separator for the rest of the arguments.

You can also solve this problem via Apache configuration using mod_remoteip, by adding the following to a conf.d file:

RemoteIPHeader X-Forwarded-For
RemoteIPInternalProxy 172.16.0.0/12
LogFormat "%a %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\"" combined

I continued to receive this error after correcting my PATH.

If your codebase requires that you have an earlier version of Python (2.7 in my case), it may have been a version prior to the existence of pip.

It's not very canonical, but installing a more recent version worked for me. (I used 2.7.13.)

If you are asking whether there's shorthand version of operator .. - no there isn't. You cannot write a ..= b. You'll have to type it in full: filename = filename .. ".tmp"

$('#dropdownid').empty();

That will remove all <option> elements underneath the dropdown element.

If you want to unselect selected items, go with the code from Russ.

I don't like the auto-commit that git revert does, so this might be helpful for some.

If you just want the modified files not the auto-commit, you can use --no-commit

% git revert --no-commit <commit hash>

which is the same as the -n

% git revert -n <commit hash>

I guess many of us who came to this page have a problem with Scikit Learn, one way to solve it is to create a dictionary with parameters and pass it to the model:

params = {'C': 1e9, 'gamma': 1e-07}
cls = SVC(**params)    

You want to do this - set a function that will be executed to respond to the onclick event:

document.getElementById('buttonLED'+id).onclick = function(){ writeLED(1,1); } ;

The things you are doing don't work because:

1. The onclick event handler expects to have a function, here you are assigning a string

   document.getElementById('buttonLED'+id).onclick = "writeLED(1,1)";
   

2. In this, you are assigning as the onclick event handler the result of executing the writeLED(1,1) function:

   document.getElementById('buttonLED'+id).onclick = writeLED(1,1);
   

EDIT based on comments:

If you have line breaks in your result set and want to remove them, make your query this way:

SELECT
    REPLACE(REPLACE(YourColumn1,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn2,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn3,CHAR(13),' '),CHAR(10),' ')
   --^^^^^^^^^^^^^^^           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   --only add the above code to strings that are having line breaks, not to numbers or dates
   FROM YourTable...
   WHERE ...

This will replace all the line breaks with a space character.

Run this to "get" all characters permitted in a char() and varchar():

;WITH AllNumbers AS
(
    SELECT 1 AS Number
    UNION ALL
    SELECT Number+1
        FROM AllNumbers
        WHERE Number+1<256
)
SELECT Number AS ASCII_Value,CHAR(Number) AS ASCII_Char FROM AllNumbers
OPTION (MAXRECURSION 256)

OUTPUT:

ASCII_Value ASCII_Char

Just uncheck behavior Enabled in your storyboard -> attributes inspector.

If you're using URLRewrite to force SSL connections in your web.config, it's probably rewriting your localhost address to force https. If debugging with SSL enabled isn't important to you and you're using URLRewrite, consider adding <add input="{HTTP_HOST}" pattern="localhost" negate="true" /> into your web.config file's rewrite section. It will stop the rewrite for any localhost addresses but leave it in place in a production environment. If you're not using URLRewrite or need to debug using SSL, http://www.hanselman.com/blog/WorkingWithSSLAtDevelopmentTimeIsEasierWithIISExpress.aspx might help. It's for VS2010, but should suffice for VS2013 as well.

Seems like this is the obvious answer:

String empty = org.apache.commons.lang.StringUtils.EMPTY;

Awesome because "empty initialization" code no longer has a "magic string" and uses a constant.

All above answers perfectly gives the solution to center the form using Bootstrap 4. However, if someone wants to use out of the box Bootstrap 4 css classes without help of any additional styles and also not wanting to use flex, we can do like this.

A sample form

HTML

<div class="container-fluid h-100 bg-light text-dark">
  <div class="row justify-content-center align-items-center">
    <h1>Form</h1>    
  </div>
  <hr/>
  <div class="row justify-content-center align-items-center h-100">
    <div class="col col-sm-6 col-md-6 col-lg-4 col-xl-3">
      <form action="">
        <div class="form-group">
          <select class="form-control">
                    <option>Option 1</option>
                    <option>Option 2</option>
                  </select>
        </div>
        <div class="form-group">
          <input type="text" class="form-control" />
        </div>
        <div class="form-group text-center">
          <div class="form-check-inline">

I hope this helps someone. Thank you.

Two issues jump out:

1. Your getData never returns anything, so its promise (async functions always return a promise) will resolve with undefined when it resolves

2. The error message clearly shows you're trying to directly render the promise getData returns, rather than waiting for it to resolve and then rendering the resolution

Addressing #1: getData should return the result of calling json:

async getData(){
   const res = await axios('/data');
   return await res.json();
}

Addressig #2: We'd have to see more of your code, but fundamentally, you can't do

<SomeElement>{getData()}</SomeElement>

...because that doesn't wait for the resolution. You'd need instead to use getData to set state:

this.getData().then(data => this.setState({data}))
              .catch(err => { /*...handle the error...*/});

...and use that state when rendering:

<SomeElement>{this.state.data}</SomeElement>

Update: Now that you've shown us your code, you'd need to do something like this:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            this.getData().then(data => this.setState({data}))
                          .catch(err => { /*...handle the error...*/});
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Futher update: You've indicated a preference for using await in componentDidMount rather than then and catch. You'd do that by nesting an async IIFE function within it and ensuring that function can't throw. (componentDidMount itself can't be async, nothing will consume that promise.) E.g.:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            (async () => {
                try {
                    this.setState({data: await this.getData()});
                } catch (e) {
                    //...handle the error...
                }
            })();
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

targetList = list1.Concat(list2).ToList();

It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly. Implicit conversions may fail sometimes when using the AddRange method.

I'm pretty sure the classpath and the shared library search path have little to do with each other. According to The JNI Book (which admittedly is old), on Windows if you do not use the java.library.path system property, the DLL needs to be in the current working directory or in a directory listed in the Windows PATH environment variable.

Update:

Looks like Oracle has removed the PDF from its website. I've updated the link above to point to an instance of the PDF living at University of Texas - Arlington.

Also, you can also read Oracle's HTML version of the JNI Specification. That lives in the Java 8 section of the Java website and so hopefully will be around for a while.

Update 2:

At least in Java 8 (I haven't checked earlier versions) you can do:

java -XshowSettings:properties -version

to find the shared library search path. Look for the value of the java.library.path property in that output.

Call decode() on a bytes instance to get the text which it encodes.

str = bytes.decode()

You can convert using different methods

1. List<Element> list = Arrays.asList(array);

2. List<Element> list = new ArrayList();
Collections.addAll(list, array);

3. Arraylist list = new Arraylist();
list.addAll(Arrays.asList(array));

For more detail you can refer to http://javarevisited.blogspot.in/2011/06/converting-array-to-arraylist-in-java.html

In order to simulate the issue that you are facing, I created the following sample using SSIS 2008 R2 with SQL Server 2008 R2 backend. The example is based on what I gathered from your question. This example doesn't provide a solution but it might help you to identify where the problem could be in your case.

Created a simple CSV file with two columns namely order number and order date. As you had mentioned in your question, values of both the columns are qualified with double quotes (") and also the lines end with Line Feed (\n) with the date being the last column. The below screenshot was taken using Notepad++, which can display the special characters in a file. LF in the screenshot denotes Line Feed.

Created a simple table named dbo.Destination in the SQL Server database to populate the CSV file data using SSIS package. Create script for the table is given below.

CREATE TABLE [dbo].[Destination](
    [OrderNumber] [varchar](50) NULL,
    [OrderDate] [date] NULL
) ON [PRIMARY]
GO

On the SSIS package, I created two connection managers. SQLServer was created using the OLE DB Connection to connect to the SQL Server database. FlatFile is a flat file connection manager.

Flat file connection manager was configured to read the CSV file and the settings are shown below. The red arrows indicate the changes made.

Provided a name to the flat file connection manager. Browsed to the location of the CSV file and selected the file path. Entered the double quote (") as the text qualifier. Changed the Header row delimiter from {CR}{LF} to {LF}. This header row delimiter change also reflects on the Columns section.

No changes were made in the Columns section.

Changed the column name from Column0 to OrderNumber.

Changed the column name from Column1 to OrderDate and also changed the data type to date [DT_DATE]

Preview of the data within the flat file connection manager looks good.

On the Control Flow tab of the SSIS package, placed a Data Flow Task.

Within the Data Flow Task, placed a Flat File Source and an OLE DB Destination.

The Flat File Source was configured to read the CSV file data using the FlatFile connection manager. Below three screenshots show how the flat file source component was configured.

The OLE DB Destination component was configured to accept the data from Flat File Source and insert it into SQL Server database table named dbo.Destination. Below three screenshots show how the OLE DB Destination component was configured.

Using the steps mentioned in the below 5 screenshots, I added a data viewer on the flow between the Flat File Source and OLE DB Destination.

Before running the package, I verified the initial data present in the table. It is currently empty because I created this using the script provided at the beginning of this post.

Executed the package and the package execution temporarily paused to display the data flowing from Flat File Source to OLE DB Destination in the data viewer. I clicked on the run button to proceed with the execution.

The package executed successfully.

Flat file source data was inserted successfully into the table dbo.Destination.

Here is the layout of the table dbo.Destination. As you can see, the field OrderDate is of data type date and the package still continued to insert the data correctly.

This post even though is not a solution. Hopefully helps you to find out where the problem could be in your scenario.

iOS 7.1.1

If someone is going to need to use globally setting tint color:

[[UIView appearance] setTintColor:[UIColor whiteColor]];

In didFinishLaunchingWithOptions of AppDelegate.

Also below code will change only tab bar tint color in any viewDidLoad method:

[self.tabBarController.tabBar setTintColor:[UIColor redColor]];

The other question was closed as a duplicate of this one. I think we can safely get rid of "even or odd" problem and use the wait/notify construct as follows:

public class WaitNotifyDemoEvenOddThreads {
    /**
     * A transfer object, only use with proper client side locking!
     */
    static final class LastNumber {
        int num;
        final int limit;

        LastNumber(int num, int limit) {
            this.num = num;
            this.limit = limit;
        }
    }

    static final class NumberPrinter implements Runnable {
        private final LastNumber last;
        private final int init;

        NumberPrinter(LastNumber last, int init) {
            this.last = last;
            this.init = init;
        }

        @Override
        public void run() {
            int i = init;
            synchronized (last) {
                while (i <= last.limit) {
                    while (last.num != i) {
                        try {
                            last.wait();
                        } catch (InterruptedException e) {
                            e.printStackTrace();
                        }
                    }
                    System.out.println(Thread.currentThread().getName() + " prints: " + i);
                    last.num = i + 1;
                    i += 2;
                    last.notify();
                }
            }
        }
    }

    public static void main(String[] args) {
        LastNumber last = new LastNumber(0, 10); // or 0, 1000
        NumberPrinter odd = new NumberPrinter(last, 1);
        NumberPrinter even = new NumberPrinter(last, 0);
        new Thread(odd, "o").start();
        new Thread(even, "e").start();
    }
}

Error message while running the code:

Begin the entityManager transaction -> createNativeQuery -> execute update -> entityManager transaction commit to save it in your database. It is working fine for me with Hibernate and postgresql.

Code

entityManager.getTransaction().begin();
Query query = entityManager.createNativeQuery("UPDATE tunable_property SET tunable_property_value = :tunable_property_value WHERE tunable_property_name = :tunable_property_name");
query.setParameter("tunable_property_name", tunablePropertyEnum.eEnableJobManager.getName());

2018 answer

Use clipboard-cli. It works with macOS, Windows, Linux, OpenBSD, FreeBSD, and Android without any real issues.

Install it with:

npm install -g clipboard-cli

Then you can do:

echo foo | clipboard 

If you want, you can alias to cb by putting the following in your .bashrc, .bash_profile, or .zshrc:

alias cb=clipboard

Update your project level build.gradle to latest version - it works for me

classpath 'com.android.tools.build:gradle:3.2.1'
classpath 'com.google.gms:google-services:4.2.0'

The problem here can be formulated another way: how do I make a config that works both in apache 2.2 and 2.4?

Require all granted is only in 2.4, but Allow all ... stops working in 2.4, and we want to be able to rollout a config that works in both.

The only solution I found, which I am not sure is the proper one, is to use:

# backwards compatibility with apache 2.2
Order allow,deny
Allow from all

# forward compatibility with apache 2.4
Require all granted
Satisfy Any

This should resolve your problem, or at least did for me. Now the problem will probably be much harder to solve if you have more complex access rules...

See also this fairly similar question. The Debian wiki also has useful instructions for supporting both 2.2 and 2.4.

Go to facebook developer dashboard Select settings -> select WEB(for website) -> Add platform Add your site URL.

This should resolve your issue.

This will do the trick. Just pass it your select element a la: document.getElementById('lstALL') when you need your list sorted.

function sortSelect(selElem) {
    var tmpAry = new Array();
    for (var i=0;i<selElem.options.length;i++) {
        tmpAry[i] = new Array();
        tmpAry[i][0] = selElem.options[i].text;
        tmpAry[i][1] = selElem.options[i].value;
    }
    tmpAry.sort();
    while (selElem.options.length > 0) {
        selElem.options[0] = null;
    }
    for (var i=0;i<tmpAry.length;i++) {
        var op = new Option(tmpAry[i][0], tmpAry[i][1]);
        selElem.options[i] = op;
    }
    return;
}

You can try this

string s1 = "Hello";
string s2 = "el";
if(strstr(s1.c_str(),s2.c_str()))
{
   cout << " S1 Contains S2";
}

the usage of Edward Brey's answer in Kotlin

 view.setOnTouchListener(object: OnSwipeTouchListener(this) {
      override fun onSwipeLeft() {
        super.onSwipeLeft()
      }
      override fun onSwipeRight() {
        super.onSwipeRight()
      }
    }
 )

"Better" is subjective.

querySelector is the newer feature.

getElementById is better supported than querySelector.

querySelector is better supported than getElementsByClassName.

querySelector lets you find elements with rules that can't be expressed with getElementById and getElementsByClassName

You need to pick the appropriate tool for any given task.

(In the above, for querySelector read querySelector / querySelectorAll).

Unfortunately, MySQL does not explicitly support that (except for dumping and reloading database again).

From http://dev.mysql.com/doc/refman/5.1/en/rename-database.html:

13.1.32. RENAME DATABASE Syntax

RENAME {DATABASE | SCHEMA} db_name TO new_db_name;

This statement was added in MySQL 5.1.7 but was found to be dangerous and was removed in MySQL 5.1.23. ... Use of this statement could result in loss of database contents, which is why it was removed. Do not use RENAME DATABASE in earlier versions in which it is present.

Strlen command is working for me . You can try following code.

// char *s

unsigned int  strLength=strlen(s);

You need to create an XmlReaderSettings instance and pass that to your XmlReader when you create it. Then you can subscribe to the ValidationEventHandler in the settings to receive validation errors. Your code will end up looking like this:

using System.Xml;
using System.Xml.Schema;
using System.IO;

public class ValidXSD
{
    public static void Main()
    {

        // Set the validation settings.
        XmlReaderSettings settings = new XmlReaderSettings();
        settings.ValidationType = ValidationType.Schema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessInlineSchema;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ProcessSchemaLocation;
        settings.ValidationFlags |= XmlSchemaValidationFlags.ReportValidationWarnings;
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);

        // Create the XmlReader object.
        XmlReader reader = XmlReader.Create("inlineSchema.xml", settings);

        // Parse the file. 
        while (reader.Read()) ;

    }
    // Display any warnings or errors.
    private static void ValidationCallBack(object sender, ValidationEventArgs args)
    {
        if (args.Severity == XmlSeverityType.Warning)
            Console.WriteLine("\tWarning: Matching schema not found.  No validation occurred." + args.Message);
        else
            Console.WriteLine("\tValidation error: " + args.Message);

    }
}

The Eclipse Word-Wrap plugin works for any type of file for me.

It's not that much work to make a function that's allocating the needed memory for your string. That's a little c-function i wrote some time ago, i always use it to read in strings.

It will return the read string or if a memory error occurs NULL. But be aware that you have to free() your string and always check for it's return value.

#define BUFFER 32

char *readString()
{
    char *str = malloc(sizeof(char) * BUFFER), *err;
    int pos;
    for(pos = 0; str != NULL && (str[pos] = getchar()) != '\n'; pos++)
    {
        if(pos % BUFFER == BUFFER - 1)
        {
            if((err = realloc(str, sizeof(char) * (BUFFER + pos + 1))) == NULL)
                free(str);
            str = err;
        }
    }
    if(str != NULL)
        str[pos] = '\0';
    return str;
}

Andrey Tarasevich provides the following explanation:

1. On Google Groups
2. On bytes.com

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

I used this way in my code

$(function(){
    $('.block').affix();
})

If you are specifically looking for getting the difference between two files, then this might help:

with open('first_file', 'r') as file1:
    with open('second_file', 'r') as file2:
        difference = set(file1).difference(file2)

difference.discard('\n')

with open('diff.txt', 'w') as file_out:
    for line in difference:
        file_out.write(line)

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _
            Filename:=Application.ActiveWorkbook.FullName, _
            HasFieldNames:=True, _
            Range:="Folio_Data_original$A1:B10"
    acc.CloseCurrentDatabase
    acc.Quit
    Set acc = Nothing
End Sub

It doesn't sound like a good idea to use send message. I think you should try to work around the problem that the DLLs can't reference each other...

do you like it

print(fr"\{''}")

or how about this

print(r"\ "[0])

In case nothing of the previous answers worked, add one of these paths to your PATH environment variable:

C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x64
C:\Program Files (x86)\Windows Kits\10\Redist\ucrt\DLLs\x86

Of course, make sure they exist first and that they contain the DLL files needed. If they don't exist, try installing "Windows Universal CRT SDK" from the Visual Studio 2015 or Visual Studio 2017 installer.

ExpressiveAnnotations gives you such a possibility:

[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }

Do “chmod +x script”

Now try executing

In [6]: x = -2
In [7]: x
Out[7]: -2

In [8]: abs(x)
Out[8]: 2

Actually abs will return the absolute value of any number. Absolute value is always a non-negative number.

You can also add stderr as well, based on shx2's answer above using class multifile :

class Log(object):

    def __init__(self, path_log, mode="w", encoding="utf-8"):
        h = open(path_log, mode, encoding=encoding)
        sys.stdout = multifile([ sys.stdout, h ])
        sys.stderr = multifile([ sys.stderr, h ])

    def __enter__(self):
        """ Necessary if called by with (or with... as) """
        return self     # only necessary if "as"

    def __exit__(self, type, value, tb):
        """ Necessary if call by with """
        pass

    def __del__(self):
        if sys is not None:
            # restoring
            sys.stdout = sys.__stdout__
            sys.stderr = sys.__stderr__

log = Log("test.txt")
print("line 1")
print("line 2", file=sys.stderr)
del log
print("line 3 only on screen")

If you're doing this in the context of a asp.Net Core API action, the conversion to Json is done implicitly.

[HttpGet]
public ActionResult Get()
{
    return Ok(TheList);
}

This is my utils service:

angular.module('myApp', []).service('Utils', function Utils($timeout) {
    var Super = this;

    this.doWhenReady = function(scope, callback, args) {
        if(!scope.$$phase) {
            if (args instanceof Array)
                callback.apply(scope, Array.prototype.slice.call(args))
            else
                callback();
        }
        else {
            $timeout(function() {
                Super.doWhenReady(scope, callback, args);
            }, 250);
        }
    };
});

and this is an example for it's usage:

angular.module('myApp').controller('MyCtrl', function ($scope, Utils) {
    $scope.foo = function() {
        // some code here . . .
    };

    Utils.doWhenReady($scope, $scope.foo);

    $scope.fooWithParams = function(p1, p2) {
        // some code here . . .
    };

    Utils.doWhenReady($scope, $scope.fooWithParams, ['value1', 'value2']);
};

Add the following 2 lines

var regex = new Regex(Regex.Escape(","));
sb_trim = regex.Replace(sb_trim, " ", 1);

If sb_trim= John,Smith,100000,M the above code will return "John Smith,100000,M"

Open the file using vi or nano. and then press " i " ,

For save and quit

  Enter Esc    

and write the following command

  :wq

without save and quit

  :q!

From kafka 1.1

Purge a topic

bin/kafka-configs.sh --zookeeper localhost:2181 --alter --entity-type topics --entity-name tp_binance_kline --add-config retention.ms=100

wait 1 minute, to be secure that kafka purge the topic remove the configuration, and then go to default value

Your JSON string is malformed: the type of center is an array of invalid objects. Replace [ and ] with { and } in the JSON string around longitude and latitude so they will be objects:

[
    {
        "name" : "New York",
        "number" : "732921",
        "center" : {
                "latitude" : 38.895111, 
                "longitude" : -77.036667
            }
    },
    {
        "name" : "San Francisco",
        "number" : "298732",
        "center" : {
                "latitude" : 37.783333, 
                "longitude" : -122.416667
            }
    }
]

Your code could look more like:

<?php
session_start();
$errorMsg = "";
$validUser = $_SESSION["login"] === true;
if(isset($_POST["sub"])) {
  $validUser = $_POST["username"] == "admin" && $_POST["password"] == "password";
  if(!$validUser) $errorMsg = "Invalid username or password.";
  else $_SESSION["login"] = true;
}
if($validUser) {
   header("Location: /login-success.php"); die();
}
?>
<!DOCTYPE html>
<html>
<head>
  <meta http-equiv="content-type" content="text/html;charset=utf-8" />
  <title>Login</title>
</head>
<body>
  <form name="input" action="" method="post">
    <label for="username">Username:</label><input type="text" value="<?= $_POST["username"] ?>" id="username" name="username" />
    <label for="password">Password:</label><input type="password" value="" id="password" name="password" />
    <div class="error"><?= $errorMsg ?></div>
    <input type="submit" value="Home" name="sub" />
  </form>
</body>
</html>

Now, when the page is redirected based on the header('LOCATION:wherever.php), put session_start() at the top of the page and test to make sure $_SESSION['login'] === true. Remember that == would be true if $_SESSION['login'] == 1 as well. Of course, this is a bad idea for security reasons, but my example may teach you a different way of using PHP.

As Matt has said, use Console.Write. I would also recommend explicitly flushing the output, however - I believe WriteLine does this automatically, but I'd seen oddities when just using Console.Write and then waiting. So Matt's code becomes:

Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();

When wrapping a pointer in a unique_ptr you cannot have multiple copies of unique_ptr. The shared_ptr holds a reference counter which count the number of copies of the stored pointer. Each time a shared_ptr is copied, this counter is incremented. Each time a shared_ptr is destructed, this counter is decremented. When this counter reaches 0, then the stored object is destroyed.

Probably my question should have been more specific. I actually know a base class for the string so solved it by:

ReportClass report = (ReportClass)Activator.CreateInstance(Type.GetType(reportClass));

The Activator.CreateInstance class has various methods to achieve the same thing in different ways. I could have cast it to an object but the above is of the most use to my situation.

Not just mvn, for any util, you can find out yourself by giving yum whatprovides {command_name}

This one works fine for me :

theme.applyStyle(R.style.AppTheme, true)

Usage:

  override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    //The call goes right after super.onCreate() and before setContentView()
    theme.applyStyle(R.style.AppTheme, true)
    setContentView(layoutId)
    onViewCreated(savedInstanceState)
}

(edit: the following applies to C# and similar, strongly-typed programming languages. I'm not sure if this helps you).

For example, the following error will be detected by the compiler (at compile time) before you run a program and will result in a compilation error:

int i = "string"; --> error at compile-time

On the other hand, an error like the following can not be detected by the compiler. You will receive an error/exception at run-time (when the program is run).

Hashtable ht = new Hashtable();
ht.Add("key", "string");
// the compiler does not know what is stored in the hashtable
// under the key "key"
int i = (int)ht["key"];  // --> exception at run-time

General purpose normalisation function to format any timestamp from any timezone to other. Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')

/**
 * Convert Datetime from any given olsonzone to other.
 * @return datetime in user specified format
 */

function datetimeconv($datetime, $from, $to)
{
    try {
        if ($from['localeFormat'] != 'Y-m-d H:i:s') {
            $datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
        }
        $datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
        $datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
        return $datetime->format($to['localeFormat']);
    } catch (\Exception $e) {
        return null;
    }
}

Usage:

$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];

$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];

datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"

All the methods are actually discouraged, it's a warning in Netbeans 7.4 and it surely is a good practice not to access superglobal variables directly, use a filter instead

$fromPerson = filter_input(INPUT_POST, 'fromPerson', FILTER_DEFAULT);
if($fromPerson === NULL) { /*$fromPerson is not present*/ }
else{ /*present*/ }
var_dump($fromPerson);exit(0);

I had the same problem into my Spring Boot+Spring Data project when invoking to a @RepositoryRestResource.

The problem is the MIME type returned; which is application/hal+json. Adding it to the server.compression.mime-types property solved this problem for me.

Hope this helps to someone else!

Why is $observe different than $watch?

The watchExpression is evaluated and compared to the previous value each digest() cycle, if there's a change in the watchExpression value, the watch function is called.

$observe is specific to watching for interpolated values. If a directive's attribute value is interpolated, eg dir-attr="{{ scopeVar }}", the observe function will only be called when the interpolated value is set (and therefore when $digest has already determined updates need to be made). Basically there's already a watcher for the interpolation, and the $observe function piggybacks off that.

See $observe & $set in compile.js

You want the NPGSQL library. Your only other alternative is ODBC.

This code counts rows with date range:

Controller:

$this->load->model("YourModelName");
$data ['query'] = $this->YourModelName->get_report();

Model:

  public function get_report()
     {   
       $query = $this->db->query("SELECT  *
FROM   reservation WHERE arvdate <= '2016-7-20' AND  dptrdate >= '2016-10-25' ");
       return $query;
     }

where 'arvdate' and 'dptrdate' are two dates on database and 'reservation' is the table name.

View:

<?php
 echo $query->num_rows();
?>

This code is to return number of rows. To return table data, then use

$query->rows();
return $row->table_column_name;

In Spring all source files are inside src/main/java. Similarly, the resources are generally kept inside src/main/resources. So keep your spring configuration file inside resources folder.

Make sure you have the ClassPath entry for your files inside src/main/resources as well.

In .classpath check for the following 2 lines. If they are missing add them.

<classpathentry path="src/main/java" kind="src"/>
<classpathentry path="src/main/resources" kind="src" />

So, if you have everything in place the below code should work.

ApplicationContext ctx = new ClassPathXmlApplicationContext("Spring-Module.xml");

I think I figured it out. Here's what I did (perhaps not the most elegant solution - suggestions on how to imp[rove this are very much welcome)

#names of columns in data frame
cols <- names(DF)
# character variables
cols.char <- c("fx_code","date")
#numeric variables
cols.num <- cols[!cols %in% cols.char]

DF.char <- DF[cols.char]
DF.num <- as.data.frame(lapply(DF[cols.num],as.numeric))
DF2 <- cbind(DF.char, DF.num)

Luckily git stash pop does not change the stash in the case of a conflict!

So nothing, to worry about, just clean up your code and try it again.

Say your codebase was clean before, you could go back to that state with: git checkout -f
Then do the stuff you forgot, e.g. git merge missing-branch
After that just fire git stash pop again and you get the same stash, that conflicted before.

Keep in mind: The stash is safe, however, uncommitted changes in the working directory are of course not. They can get messed up.

I'd like to expand on Obertklep's answer. In his example it is an NPM module called body-parser which is doing most of the work. Where he puts req.body.name, I believe he/she is using body-parser to get the contents of the name attribute(s) received when the form is submitted.

If you do not want to use Express, use querystring which is a built-in Node module. See the answers in the link below for an example of how to use querystring.

It might help to look at this answer, which is very similar to your quest.

All answers are correct. Meta-inf has many purposes. In addition, here is an example about using tomcat container.

Go to Tomcat Doc and check " Standard Implementation > copyXML " attribute.

Description is below.

Set to true if you want a context XML descriptor embedded inside the application (located at /META-INF/context.xml) to be copied to the owning Host's xmlBase when the application is deployed. On subsequent starts, the copied context XML descriptor will be used in preference to any context XML descriptor embedded inside the application even if the descriptor embedded inside the application is more recent. The flag's value defaults to false. Note if the deployXML attribute of the owning Host is false or if the copyXML attribute of the owning Host is true, this attribute will have no effect.

Try putting your image into a container like so:

HTML:

<div>
    <img src="http://www.testimoniesofheavenandhell.com/Animal-Pictures/wp-content/uploads/2013/04/Dog-Animal-Picture-Siberian-Husky-Puppy-HD-Wallpaper.jpg" />
</div>

CSS:

div
{
    width: 200px;
    height: 200px;
    overflow: hidden;
}

div > img
{
    width: 300px;
}

Here's a fiddle.

Make the accepted answer respond for small screens when smaller than the fixed width.

HTML:

<table>
  <tr>
    <th>header 1</th>
    <th>header 234567895678657</th>

If you want to do the following by using JSTL Tag Libe, please follow the following steps:

[Requirement] if a number is a grater than equal 40 and lower than 50 then display "Two digit number starting with 4" otherwise "Other numbers".

[Solutions]

1. Please Add the JSTL tag lib on the top of the page.`
     <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>`

2. Please Write the following code
`
<c:choose>
       <c:when test="${params.number >=40 && params.number <50}">
              <p> Two digit number starting with 4. </p>
       </c:when>
       <c:otherwise>
              <p> Other numbers. </p>
       </c:otherwise>
  </c:choose>`

You can't easily decrypt the password from the hash string that you see. You should rather replace the hash string with a new one from a password that you do know.

There's a good howto here:

https://jakebillo.com/wordpress-phpass-generator-resetting-or-creating-a-new-admin-user/

Basically:

1. generate a new hash from a known password using e.g. http://scriptserver.mainframe8.com/wordpress_password_hasher.php, as described in the above link, or any other product that uses the phpass library,
2. use your DB interface (e.g. phpMyAdmin) to update the user_pass field with the new hash string.

If you have more users in this WordPress installation, you can also copy the hash string from one user whose password you know, to the other user (admin).

  var json = {"ListID" : "1", "ItemName":"test"};
    $.ajax({
            url: url,
            type: 'POST',        
            data: username, 
            cache:false,
            beforeSend: function(xhr) {  
                xhr.setRequestHeader("Accept", "application/json");  
                xhr.setRequestHeader("Content-Type", "application/json");  
            },       
            success:function(response){
             console.log("Success")
            },
              error : function(xhr, status, error) {
            console.log("error")
            }
);

Summary

Microsoft Security Updates 896358 & 840315 block display of CHM file contents when opened from a network drive (or a UNC path). This is Windows' attempt to stop attack vectors for viruses/malware from infecting your computer and has blocked out the .chm file that draw data over the "InfoTech" protocol, which this chm file uses.

Microsoft's summary of the problem: http://support.microsoft.com/kb/896054

Solutions

1. If you are using Windows Server 2008, Windows 7, windows has created a quick fix. Right click the chm file, and you will get the "yourfile.chm Properties" dialog box, at the bottom, a button called "Unblock" appears. Click Unblock and press OK, and try to open the chm file again, it works correctly. This option is not available for earlier versions of Windows before WindowsXP (SP3).

   

2. Solve the problem by moving your chm file OFF the network drive. You may be unaware you are using a network drive, double check now: Right click your .chm file, click properties and look at the "location" field. If it starts with two backslashes like this: \\epicserver\blah\, then you are using a networked drive. So to fix it, Copy the chm file, and paste it into a local drive, like C:\ or E:. Then try to reopen the chm file, windows does not freak out.

3. Last resort, if you can't copy/move the file off the networked drive. If you must open it where it sits, and you are using a lesser version of windows like XP, Vista, ME or other, you will have to manually tell Windows not to freak out over this .chm file. HHReg (HTML Help Registration Utility) Utility Automates this Task. Basically you download the HHReg utility, load your .chm file, press OK, and it will create the necessary registry keys to tell Windows not to block it. For more info: http://www.winhelponline.com/blog/fix-cannot-view-chm-files-network-xp-2003-vista/

Windows 8 or 10? --> Upgrade to Windows XP.

As mentioned in the presentation at the I/O (about 4:05), Volley "is terrible" for large payloads. As I understand it that means not to use Volley for receiving/sending (big) files. Looking at the code it seems that it is not even designed to handle multipart form data (e.g. Request.java has getBodyContentType() with hardcoded "application/x-www-form-urlencoded"; HttpClientStack::createHttpRequest() can handle only byte[], etc...). Probably you will be able to create implementation that can handle multipart but If I were you I will just use HttpClient directly with MultipartEntity like:

    HttpPost req = new HttpPost(composeTargetUrl());
    MultipartEntity entity = new MultipartEntity();
    entity.addPart(POST_IMAGE_VAR_NAME, new FileBody(toUpload));
    try {
        entity.addPart(POST_SESSION_VAR_NAME, new StringBody(uploadSessionId));
    } catch (UnsupportedEncodingException e) {
        throw new RuntimeException(e);
    }
    req.setEntity(entity);

You may need newer HttpClient (i.e. not the built-in) or even better, use Volley with newer HttpClient

Try this:

echo mysql_result($result, 0);

This is enough because you are only fetching one field of one row.

1. make sure the device is set for usb debugging
2. Have the adb client running (e.g. via "adb usb" or adb start-server"
3. LEAVE the device connected via usb!!!
4. AND THEN reboot the device.

This always brings my Motorola MB525 "online" again, after adb complains it would be "offline". I'm using OSX btw.

exec('wget http://<url to the php script>') worked for me.

If you want to modify your List during traversal, then you need to use the Iterator. And then you can use iterator.remove() to remove the elements during traversal.

var arr = [
  {
  "id": "1",
  "msg": "hi",
  "tid": "2013-05-05 23:35",
  "fromWho": "[email protected]"
  }, {
  "id": "2",
  "msg": "there",
  "tid": "2013-05-05 23:45",
  "fromWho": "[email protected]"
  }
];

forEach method for easy implementation.

arr.forEach(function(item){
  console.log('ID: ' + item.id);
  console.log('MSG: ' + item.msg);
  console.log('TID: ' + item.tid);
  console.log('FROMWHO: ' + item.fromWho);
});

Yes:

df -k .

for the current directory.

df -k /some/dir

if you want to check a specific directory.

You might also want to check out the stat(1) command if your system has it. You can specify output formats to make it easier for your script to parse. Here's a little example:

$ echo $(($(stat -f --format="%a*%S" .)))

one kind of join a query in mongoDB, is ask at one collection for id that match , put ids in a list (idlist) , and do find using on other (or same) collection with $in : idlist

u = db.friends.find({"friends": something }).toArray()
idlist= []
u.forEach(function(myDoc) { idlist.push(myDoc.id ); } )
db.family.find({"id": {$in : idlist} } )

public static void printTwoDimensionalArray(int[][] a) {
    for (int i = 0; i < a.length; i++) {
        for (int j = 0; j < a[i].length; j++) {
            System.out.printf("%d ", a[i][j]);
        }
        System.out.println();
    }
}

just for int array

Here are some ways to edit the text and the size of the box:

rows="insertNumber"
cols="insertNumber"
style="font-size:12pt"

Example:

<textarea rows="5" cols="30" style="font-size: 12pt" id="myText">Enter 
Text Here</textarea>

Recent private repositories have a search field for searching through that repo.

Bafflingly, it looks like this functionality is not available to public repositories, though.

You can do something like this:

    public myform()
    {
         InitializeComponent(); // this will be called in ComboBox ComboBox = new System.Windows.Forms.ComboBox();
    }

    private void Form1_Load(object sender, EventArgs e)
    {
        // TODO: This line of code loads data into the 'myDataSet.someTable' table. You can move, or remove it, as needed.
        this.myTableAdapter.Fill(this.myDataSet.someTable);
        comboBox1.SelectedItem = null;
        comboBox1.SelectedText = "--select--";           
    }

String allocates dynamic memory size in the heap of your RAM. But string address is stored in stack that occupies 4 bytes of memory.

It means there is an extension=... or zend_extension=... line in one of your php configuration files (php.ini, or another close to it) that is trying to load that extension : ixed.5.2.lin

Unfortunately that file or path doesn't exist or the permissions are incorrect.

1. Try to search in the .ini files that are loaded by PHP (phpinfo() can indicate which ones are) - one of them should try to load that extension.
2. Either correct the path to the file or comment out the corresponding line.

It is probably failing because 1.0.0 is an annotated tag. Perhaps you saw the following error message:

error: Trying to write non-commit object to branch refs/heads/master

Annotated tags have their own distinct type of object that points to the tagged commit object. Branches can not usefully point to tag objects, only commit objects. You need to “peel” the annotated tag back to commit object and push that instead.

git push production +1.0.0^{commit}:master
git push production +1.0.0~0:master          # shorthand

There is another syntax that would also work in this case, but it means something slightly different if the tag object points to something other than a commit (or a tag object that points to (a tag object that points to a …) a commit).

git push production +1.0.0^{}:master

These tag peeling syntaxes are described in git-rev-parse(1) under Specifying Revisions.

I fear this might turn out to BE the long way round but could depend on how big your data set is – presumably more than four months for example.

Assuming your data is in ColumnA:C and has column labels in Row 1, also that Month is formatted mmm(this last for ease of sorting):

1. Sort the data by Name then Month
2. Enter in D2 =IF(AND(A2=A1,C2=C1),D1+1,1) (One way to deal with what is the tricky issue of multiple entries for the same person for the same month).
3. Create a pivot table from A1:D(last occupied row no.)
4. Say insert in F1.
5. Layout as in screenshot.

I’m hoping this would be adequate for your needs because pivot table should automatically update (provided range is appropriate) in response to additional data with refresh. If not (you hard taskmaster), continue but beware that the following steps would need to be repeated each time the source data changes.

5. Copy pivot table and Paste Special/Values to, say, L1.
6. Delete top row of copied range with shift cells up.
7. Insert new cell at L1 and shift down.
8. Key 'Name' into L1.
9. Filter copied range and for ColumnL, select Row Labels and numeric values.
10. Delete contents of L2:L(last selected cell)
11. Delete blank rows in copied range with shift cells up (may best via adding a column that counts all 12 months). Hopefully result should be as highlighted in yellow.

Happy to explain further/try again (I've not really tested this) if does not suit.

EDIT (To avoid second block of steps above and facilitate updating for source data changes)

.0. Before first step 2. add a blank row at the very top and move A2:D2 up.
.2. Adjust cell references accordingly (in D3 =IF(AND(A3=A2,C3=C2),D2+1,1).
.3. Create pivot table from A:D

.6. Overwrite Row Labels with Name.
.7. PivotTable Tools, Design, Report Layout, Show in Tabular Form and sort rows and columns A>Z.
.8. Hide Row1, ColumnG and rows and columns that show (blank).

Steps .0. and .2. in the edit are not required if the pivot table is in a different sheet from the source data (recommended).

Step .3. in the edit is a change to simplify the consequences of expanding the source data set. However introduces (blank) into pivot table that if to be hidden may need adjustment on refresh. So may be better to adjust source data range each time that changes instead: PivotTable Tools, Options, Change Data Source, Change Data Source, Select a table or range). In which case copy rather than move in .0.

On Windows with the ActiveState distribution of Perl, use the ppm command.

Short answer, you can't.

HTML is used for the page's structure and can't send e-mails, you will need a server side language (such as PHP) to send e-mails, you can also use a third party service and let them handle the e-mail sending for you.

If you want to check the display value, https://stackoverflow.com/a/1189281/5622596 already posted the answer.

However if instead of checking whether an element has a style of style="display:none" you want to know if that element is visible. Then use .is(":visible")

For example: $('#idDetails').is(":visible");

This will be true if it is visible & false if it is not.

For "partial" I always use it as follows:

If there's something you need to include in a page that you need to go via the controller (like you would with an Ajax call) then use "Html.RenderPartial".

If you have a 'static' include that isn't linked to a controller per-se and just in the 'shared' folder for example, use "HTML.partial"

Good-old Array.prototype.reduce:

const selectable = {a: null, b: null};
const v = {a: true, b: 'yes', c: 4};

const r = Object.keys(selectable).reduce((a, b) => {
  return (a[b] = v[b]), a;
}, {});

console.log(r);

this answer uses the magical comma-operator, also: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comma_Operator

if you want to get really fancy, this is more compact:

const r = Object.keys(selectable).reduce((a, b) => (a[b] = v[b], a), {});

Putting it all together into a reusable function:

const getSelectable = function (selectable, original) {
  return Object.keys(selectable).reduce((a, b) => (a[b] = original[b], a), {})
};

const r = getSelectable(selectable, v);
console.log(r);

I think I had a better output, especially for a double datatype sorting.

Though this question has been marked answered, perhaps this will help someone else;

Arrays.sort(newTag, new Comparator<String[]>() {
         @Override
         public int compare(final String[] entry1, final String[] entry2) {
              final Integer time1 = (int)Integer.valueOf((int) Double.parseDouble(entry1[2]));
              final Integer time2 = (int)Integer.valueOf((int) Double.parseDouble(entry2[2]));
              return time1.compareTo(time2);
         }
    });

SELECT vg.id, 
       vg.name
  FROM v_groups vg INNER JOIN  
       people2v_groups p2vg ON vg.id = p2vg.v_group_id
 WHERE p2vg.people_id = 0;

A better solution for "today" is:

SELECT * FROM jokes WHERE DATE(date) = DATE(NOW())

In c++, compiler always ensure that functions in object hierarchy are called successfully. These functions are constructors and destructors and object hierarchy means inheritance tree.

According to this rule we can guess compiler will call constructors and destructors for each object in inheritance hierarchy even if we don't implement it. To perform this operation compiler will synthesize the undefined constructors and destructors for us and we name them as a default constructors and destructors.Then, compiler will call default constructor of base class and then calls constructor of derived class.

In your case you don't call base class constructor but compiler does that for you by calling default constructor of base class because if compiler didn't do it your derived class which is Rectangle in your example will not be complete and it might cause disaster because maybe you will use some member function of base class in your derived class. So for the sake of safety compiler always need all constructor calls.

To get the instance metadata use

wget -q -O - http://169.254.169.254/latest/meta-data/instance-id

A bit late, but maybe someone finds it useful.

For me, ISNULL was out of question due to the table scan. UNION ALL would need me to repeat a complex query, and due to me selecting only the TOP X it would not have been very efficient.

If you are able to change the table design, you can:

1. Add another field, just for sorting, such as Next_Contact_Date_Sort.

2. Create a trigger that fills that field with a large (or small) value, depending on what you need:

   CREATE TRIGGER FILL_SORTABLE_DATE ON YOUR_TABLE AFTER INSERT,UPDATE AS 
   BEGIN
       SET NOCOUNT ON;
       IF (update(Next_Contact_Date)) BEGIN
       UPDATE YOUR_TABLE SET Next_Contact_Date_Sort=IIF(YOUR_TABLE.Next_Contact_Date IS NULL, 99/99/9999, YOUR_TABLE.Next_Contact_Date_Sort) FROM inserted i WHERE YOUR_TABLE.key1=i.key1 AND YOUR_TABLE.key2=i.key2
       END
   END
   

What about gethostname()?

Edit: This might not be an option I suppose, depending on your environment. It's new in PHP 5.3. php_uname('n') might work as an alternative.

The issue is how you're attempting to get the value. Things like...

if ( document.frm_new_user_request.u_isid.value == '' )

won't work. You need to find the element you want to get the value of first. It's not quite like a server side language where you can type in an object's reference name and a period to get or assign values.

document.getElementById('[id goes here]').value;

will work. Note: JavaScript is case-sensitive

I would recommend using:

var variablename = document.getElementById('[id goes here]');

or

var variablename = document.getElementById('[id goes here]').value;

The ALTER TABLE statement presented by Chris should work, but first you need to declare the columns NOT NULL. All parts of a primary key need to be NOT NULL.

Before teaching yourself Spring and Struts, you should probably learn Java. Output like this

org.classes.database.Employee@d9b02

is the result of the Object#toString() method which all objects inherit from the Object class, the superclass of all classes in Java.

The List sub classes implement this by iterating over all the elements and calling toString() on those. It seems, however, that you haven't implemented (overriden) the method in your Employee class.

Your JSTL here

<c:forEach items="${eList}" var="employee">
    <tr>
        <td>Employee ID: <c:out value="${employee.eid}"/></td>
        <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
    </tr>
</c:forEach>

is fine except for the fact that you don't have a page, request, session, or application scoped attribute named eList.

You need to add it

<% List eList = (List)session.getAttribute("empList");
   request.setAttribute("eList", eList);
%>

Or use the attribute empList in the forEach.

<c:forEach items="${empList}" var="employee">
    <tr>
        <td>Employee ID: <c:out value="${employee.eid}"/></td>
        <td>Employee Pass: <c:out value="${employee.ename}"/></td>  
    </tr>
</c:forEach>

Multiple $(document).ready() will fire in order top down on the page. The last $(document).ready() will fire last on the page. Inside the last $(document).ready(), you can trigger a new custom event to fire after all the others..

Wrap your code in an event handler for the new custom event.

<html>
<head>
<script>
    $(document).on("my-event-afterLastDocumentReady", function () {
        // Fires LAST
    });
    $(document).ready(function() {
        // Fires FIRST
    });
    $(document).ready(function() {
        // Fires SECOND
    });
    $(document).ready(function() {
        // Fires THIRD
    });
</script>
<body>
... other code, scripts, etc....
</body>
</html>

<script>
    $(document).ready(function() {
        // Fires FOURTH
        // This event will fire after all the other $(document).ready() functions have completed.
        // Usefull when your script is at the top of the page, but you need it run last
        $(document).trigger("my-event-afterLastDocumentReady");
    });
</script>

Have you tried:

result = db.engine.execute("<sql here>")

or:

from sqlalchemy import text

sql = text('select name from penguins')
result = db.engine.execute(sql)
names = [row[0] for row in result]
print names

I wasn't able to use Model::truncate() as it would error:

SQLSTATE[42000]: Syntax error or access violation: 1701 Cannot truncate a table referenced in a foreign key constraint

And unfortunately Model::delete() doesn't work (at least in Laravel 5.0):

Non-static method Illuminate\Database\Eloquent\Model::delete() should not be called statically, assuming $this from incompatible context

But this does work:

(new Model)->newQuery()->delete()

That will soft-delete all rows, if you have soft-delete set up. To fully delete all rows including soft-deleted ones you can change to this:

(new Model)->newQueryWithoutScopes()->forceDelete()

Update (2017): The following two libraries have now become the most common drop-down libraries used with Javascript. While they are jQuery-native, they have been customized to work with everything from AngularJS 1.x to having custom CSS for Bootstrap. (Chosen JS, the original answer here, seems to have dropped to #3 in popularity.)

• Select2: https://select2.github.io/
• Selectize: http://selectize.github.io/selectize.js/

Obligatory screenshots below.

Selectize:

Original answer (2012): I think that the Chosen library might also be useful. Its available in jQuery, Prototype and MooTools versions.

Attached is a screenshot of how the multi-select functionality looks in Chosen.

Its very simple for those who are using API 21 or greater Use this code below

for Dark ActionBar

<resources>
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="android:background">@color/colorDarkGrey</item>
</style>

for_LightActionBar

<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.ActionBar">
    <item name="android:background">@color/colorDarkGrey</item>
</style>

I've used something like this before which addresses @scunliffes concern. It finds all instances of items with a class of (in this case .button), and assigns an ID and appends its index to the id name:

$(".button").attr('id', function (index) {_x000D_
 return "button-" + index;_x000D_
});

So let's say you have 3 items with the class name of .button on a page. The result would be adding a unique ID to all of them (in addition to their class of "button").

In this case, #button-0, #button-1, #button-2, respectively. This can come in very handy. Simply replace ".button" in the first line with whatever class you want to target, and replace "button" in the return statement with whatever you'd like your unique ID to be. Hope this helps!

You can use my library — NoPermission (It's just one class)

compile 'ru.alexbykov:nopermission:1.1.1'

Sample

PermissionHelper permissionHelper = new PermissionHelper(this); //don't use getActivity in fragment!

permissionHelper.check(Manifest.permission.READ_CONTACTS)
                .onSuccess(this::onSuccess)
                .onDenied(this::onDenied)
                .onNeverAskAgain(this::onNeverAskAgain)
                .run();

onRequestPermissionResult:

 @Override
  public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
        permissionHelper.onRequestPermissionsResult(requestCode, permissions, grantResults);
   }

I think api more convenient than EasyPermissions by Google.

Refer this:

@RequestMapping(value="download", method=RequestMethod.GET)
public void getDownload(HttpServletResponse response) {

// Get your file stream from wherever.
InputStream myStream = someClass.returnFile();

// Set the content type and attachment header.
response.addHeader("Content-disposition", "attachment;filename=myfilename.txt");
response.setContentType("txt/plain");

// Copy the stream to the response's output stream.
IOUtils.copy(myStream, response.getOutputStream());
response.flushBuffer();
}

Details at: https://twilblog.github.io/java/spring/rest/file/stream/2015/08/14/return-a-file-stream-from-spring-rest.html

varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.

this is a sample case, which will make sense I believe!

node('master'){
    stage('stage1'){
    def commit = sh (returnStdout: true, script: '''echo hi
    echo bye | grep -o "e"
    date
    echo lol''').split()


    echo "${commit[-1]} "

    }
}

As someone who has worked with ASP.NET API for about 3 years, I'd recommend returning an HttpResponseMessage instead. Don't use the ActionResult or IEnumerable!

ActionResult is bad because as you've discovered.

Return IEnumerable<> is bad because you may want to extend it later and add some headers, etc.

Using JsonResult is bad because you should allow your service to be extendable and support other response formats as well just in case in the future; if you seriously want to limit it you can do so using Action Attributes, not in the action body.

public HttpResponseMessage GetAllNotificationSettings()
{
    var result = new List<ListItems>();
    // Filling the list with data here...

    // Then I return the list
    return Request.CreateResponse(HttpStatusCode.OK, result);
}

In my tests, I usually use the below helper method to extract my objects from the HttpResponseMessage:

 public class ResponseResultExtractor
    {
        public T Extract<T>(HttpResponseMessage response)
        {
            return response.Content.ReadAsAsync<T>().Result;
        }
    }

var actual = ResponseResultExtractor.Extract<List<ListItems>>(response);

In this way, you've achieved the below:

• Your Action can also return Error Messages and status codes like 404 not found so in the above way you can easily handle it.
• Your Action isn't limited to JSON only but supports JSON depending on the client's request preference and the settings in the Formatter.

Look at this: http://www.asp.net/web-api/overview/formats-and-model-binding/content-negotiation

Just like you do for getting something from the CNode you also need to do for the ANode

XmlNodeList xnList = xml.SelectNodes("/Element[@*]");
foreach (XmlNode xn in xnList)
{
  XmlNode anode = xn.SelectSingleNode("ANode");
    if (anode!= null)
    {
        string id = anode["ID"].InnerText;
        string date = anode["Date"].InnerText;
        XmlNodeList CNodes = xn.SelectNodes("ANode/BNode/CNode");
        foreach (XmlNode node in CNodes)
        {
         XmlNode example = node.SelectSingleNode("Example");
         if (example != null)
         {
            string na = example["Name"].InnerText;
            string no = example["NO"].InnerText;
         }
        }
    }
}

thought I would share this, as I didnt see this anywhere, and is what I used to fix my solution.

SOLUTION: min-height: inherit;

I had a parent with a specified min height, and I needed a child to also be that height.

.parent {_x000D_
  min-height: 300px;_x000D_
  background-color: rgba(255,255,0,0.5); //yellow_x000D_
}_x000D_
_x000D_
.child {_x000D_
  min-height: inherit;_x000D_
  background-color: rgba(0,255,0,0.5); //blue_x000D_
}_x000D_
_x000D_
p {_x000D_
  padding: 20px;_x000D_
  color: red;_x000D_
  font-family: sans-serif;_x000D_
  font-weight: bold;_x000D_
  text-align: center;_x000D_
}

<div class="parent">_x000D_
  <div class="child">_x000D_
    <p>Yellow + Blue = Green :)</p>_x000D_
  </div>_x000D_
</div>

This way the child now acts as height 100% of the min-height.

I hope some people find this useful :)

While getting all album tracks form inside album class, you'll generate one more query for one more record. That's because of proxy method. There's another example of my code (see last post in topic): http://groups.google.com/group/doctrine-user/browse_thread/thread/d1d87c96052e76f7/436b896e83c10868#436b896e83c10868

Is there any other method to resolve that? Isn't a single join a better solution?

element::after { 
    display: block;
    content: " ";
}

This worked for me.

I did this by using two different text views:

1. One in the background that is used as a placeholder.
2. One in the foreground (with a transparent background) that the user actually types in.

The idea is that once the user starts typing stuff in the foreground view, the placeholder in the background disappears (and reappears if the user deletes everything). So it behaves exactly like a placeholder for the single line text field.

Here's the code I used for it. Note that descriptionField is the field the user types in and descriptionPlaceholder is the one in the background.

func textViewDidChange(descriptionField: UITextView) {
    if descriptionField.text.isEmpty == false {
        descriptionPlaceholder.text = ""
    } else {
        descriptionPlaceholder.text = descriptionPlaceholderText
    }
}

Try the following commands at first (re-run again if needed):

$ git fsck --full
$ git gc
$ git gc --prune=today
$ git fetch --all
$ git pull --rebase

And then you you still have the problems, try can:

• remove all the corrupt objects, e.g.

  fatal: loose object 91c5...51e5 (stored in .git/objects/06/91c5...51e5) is corrupt
  $ rm -v .git/objects/06/91c5...51e5
  

• remove all the empty objects, e.g.

  error: object file .git/objects/06/91c5...51e5 is empty
  $ find .git/objects/ -size 0 -exec rm -vf "{}" \;
  

• check a "broken link" message by:

  git ls-tree 2d9263c6d23595e7cb2a21e5ebbb53655278dff8
  

  This will tells you what file the corrupt blob came from!

• to recover file, you might be really lucky, and it may be the version that you already have checked out in your working tree:

  git hash-object -w my-magic-file
  

  again, and if it outputs the missing SHA1 (4b945..) you're now all done!

• assuming that it was some older version that was broken, the easiest way to do it is to do:

  git log --raw --all --full-history -- subdirectory/my-magic-file
  

  and that will show you the whole log for that file (please realize that the tree you had may not be the top-level tree, so you need to figure out which subdirectory it was in on your own), then you can now recreate the missing object with hash-object again.

• to get a list of all refs with missing commits, trees or blobs:

  $ git for-each-ref --format='%(refname)' | while read ref; do git rev-list --objects $ref >/dev/null || echo "in $ref"; done
  

  It may not be possible to remove some of those refs using the regular branch -d or tag -d commands, since they will die if git notices the corruption. So use the plumbing command git update-ref -d $ref instead. Note that in case of local branches, this command may leave stale branch configuration behind in .git/config. It can be deleted manually (look for the [branch "$ref"] section).

• After all refs are clean, there may still be broken commits in the reflog. You can clear all reflogs using git reflog expire --expire=now --all. If you do not want to lose all of your reflogs, you can search the individual refs for broken reflogs:

  $ (echo HEAD; git for-each-ref --format='%(refname)') | while read ref; do git rev-list -g --objects $ref >/dev/null || echo "in $ref"; done
  

  (Note the added -g option to git rev-list.) Then, use git reflog expire --expire=now $ref on each of those. When all broken refs and reflogs are gone, run git fsck --full in order to check that the repository is clean. Dangling objects are Ok.

Below you can find advanced usage of commands which potentially can cause lost of your data in your git repository if not used wisely, so make a backup before you accidentally do further damages to your git. Try on your own risk if you know what you're doing.

To pull the current branch on top of the upstream branch after fetching:

$ git pull --rebase

You also may try to checkout new branch and delete the old one:

$ git checkout -b new_master origin/master

To find the corrupted object in git for removal, try the following command:

while [ true ]; do f=`git fsck --full 2>&1|awk '{print $3}'|sed -r 's/(^..)(.*)/objects\/\1\/\2/'`; if [ ! -f "$f" ]; then break; fi; echo delete $f; rm -f "$f"; done

For OSX, use sed -E instead of sed -r.

Other idea is to unpack all objects from pack files to regenerate all objects inside .git/objects, so try to run the following commands within your repository:

$ cp -fr .git/objects/pack .git/objects/pack.bak
$ for i in .git/objects/pack.bak/*.pack; do git unpack-objects -r < $i; done
$ rm -frv .git/objects/pack.bak

If above doesn't help, you may try to rsync or copy the git objects from another repo, e.g.

$ rsync -varu git_server:/path/to/git/.git local_git_repo/
$ rsync -varu /local/path/to/other-working/git/.git local_git_repo/
$ cp -frv ../other_repo/.git/objects .git/objects

To fix the broken branch when trying to checkout as follows:

$ git checkout -f master
fatal: unable to read tree 5ace24d474a9535ddd5e6a6c6a1ef480aecf2625

Try to remove it and checkout from upstream again:

$ git branch -D master
$ git checkout -b master github/master

In case if git get you into detached state, checkout the master and merge into it the detached branch.

Another idea is to rebase the existing master recursively:

$ git reset HEAD --hard
$ git rebase -s recursive -X theirs origin/master

FWIW, here is a sort method for showing which processes are using the most virt memory.

memstat | sort -k 1 -t':' -g -r | less

Sort options are set to first column, using : as column seperator, numeric sort and sort in reverse.

If you have Powershell remoting and CredSSP setup then you can update your code to the following:

$Session = New-PSSession -ComputerName $Computer1 -Authentication CredSSP
$NetbackupVersion1 = Invoke-Command -Session $Session -ScriptBlock { $(Get-ItemProperty hklm:\SOFTWARE\Veritas\NetBackup\CurrentVersion).PackageVersion}
Remove-PSSession $Session

The best use case I can think of is in caching AJAX responses. Here's a modified example from Rebecca Murphey's intro post on the topic:

var cache = {};

function getData( val ){

    // return either the cached value or jqXHR object wrapped Promise
    return $.when(
        cache[ val ] || 
        $.ajax('/foo/', {
            data: { value: val },
            dataType: 'json',
            success: function( resp ){
                cache[ val ] = resp;
            }
        })
    );
}

getData('foo').then(function(resp){
    // do something with the response, which may
    // or may not have been retrieved using an
    // XHR request.
});

Basically, if the value has already been requested once before it's returned immediately from the cache. Otherwise, an AJAX request fetches the data and adds it to the cache. The $.when/.then doesn't care about any of this; all you need to be concerned about is using the response, which is passed to the .then() handler in both cases. jQuery.when() handles a non-Promise/Deferred as a Completed one, immediately executing any .done() or .then() on the chain.

Deferreds are perfect for when the task may or may not operate asynchronously, and you want to abstract that condition out of the code.

Another real world example using the $.when helper:

$.when($.getJSON('/some/data/'), $.get('template.tpl')).then(function (data, tmpl) {

    $(tmpl) // create a jQuery object out of the template
    .tmpl(data) // compile it
    .appendTo("#target"); // insert it into the DOM

});

you can use btnSubmit::before { margin-left: 20px; }

To repeat from a more unknown question, take a look at MvcIntegrationTestFramework.

It makes saves you writing your own helpers to stream result and is proven to work well enough. I'd assume this would be in a test project and as a bonus you would have the other testing capabilities once you've got this setup. Main bother would probably be sorting out the dependency chain.

 private static readonly string mvcAppPath = 
     Path.GetFullPath(AppDomain.CurrentDomain.BaseDirectory 
     + "\\..\\..\\..\\MyMvcApplication");
 private readonly AppHost appHost = new AppHost(mvcAppPath);

    [Test]
    public void Root_Url_Renders_Index_View()
    {
        appHost.SimulateBrowsingSession(browsingSession => {
            RequestResult result = browsingSession.ProcessRequest("");
            Assert.IsTrue(result.ResponseText.Contains("<!DOCTYPE html"));
        });
}

If we need to check Edge please go head with this

if(navigator.userAgent.indexOf("Edge") > 1 ){

//do something

}

For me, created an empty bootstrap.css.map together with bootstrap.css and the error stopped.

If you actually start a new thread, that thread will terminate when the method finishes:

Thread thread = new Thread(SecondFoo);
thread.Start();

Now SecondFoo will be called in the new thread, and the thread will terminate when it completes.

Did you actually mean that you wanted the thread to terminate when the method in the calling thread completes?

EDIT: Note that starting a thread is a reasonably expensive operation. Do you definitely need a brand new thread rather than using a threadpool thread? Consider using ThreadPool.QueueUserWorkItem or (preferrably, if you're using .NET 4) TaskFactory.StartNew.

we had to do this so often that I made what I called a DelegateParameter class

using System;
using System.Collections.Generic;
using System.Text;
using System.Web.UI.WebControls;
using System.Reflection;

namespace MyControls
{
    public delegate object EvaluateParameterEventHandler(object sender, EventArgs e);

    public class DelegateParameter : Parameter
    {
        private System.Web.UI.Control _parent;
        public System.Web.UI.Control Parent
        {
            get { return _parent; }
            set { _parent = value; }
        }

        private event EvaluateParameterEventHandler _evaluateParameter;
        public event EvaluateParameterEventHandler EvaluateParameter
        {
            add { _evaluateParameter += value; }
            remove { _evaluateParameter -= value; }
        }

        protected override object Evaluate(System.Web.HttpContext context, System.Web.UI.Control control)
        {
            return _evaluateParameter(this, EventArgs.Empty);
        }
    }
}

put this class either in your app_code (remove the namespace if you put it there) or in your custom control assembly. After the control is registered in the web.config you should be able to do this

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:itematConnectionString %>"
    SelectCommand = "SELECT items.name, items.id FROM items INNER JOIN users_items ON items.id = users_items.id WHERE (users_items.user_id = @userId) ORDER BY users_items.date DESC">
    <SelectParameters>
    <asp:DelegateParameter Name="userId"  DbType="Guid" OnEvaluate="GetUserID" />
    </SelectParameters>
</asp:SqlDataSource>

then in the code behind you implement the GetUserID anyway you like.

protected object GetUserID(object sender, EventArgs e)
{
  return userId;
}

try this...    
<script type="text/javascript">
    function test(){
    var av=document.getElementById("mytext").value;
    alert(av);
    }
    </script>

    <input type="text" value="" id="mytext">
    <input type="button" onclick="test()" value="go" />

Depending on your requirements, options like XML-RPC could be useful, which can be used to remotely call functions virtually in any language supporting the protocol.

To quote Jeffrey Richter from CLR via C#
(EIMI means Explicit Interface Method Implementation)

It is critically important for you to understand some ramifications that exist when using EIMIs. And because of these ramifications, you should try to avoid EIMIs as much as possible. Fortunately, generic interfaces help you avoid EIMIs quite a bit. But there may still be times when you will need to use them (such as implementing two interface methods with the same name and signature). Here are the big problems with EIMIs:

• There is no documentation explaining how a type specifically implements an EIMI method, and there is no Microsoft Visual Studio IntelliSense support.
• Value type instances are boxed when cast to an interface.
• An EIMI cannot be called by a derived type.

If you use an interface reference ANY virtual chain can be explicitly replaced with EIMI on any derived class and when an object of such type is cast to the interface, your virtual chain is ignored and the explicit implementation is called. That's anything but polymorphism.

EIMIs can also be used to hide non-strongly typed interface members from basic Framework Interfaces' implementations such as IEnumerable<T> so your class doesn't expose a non strongly typed method directly, but is syntactical correct.

To improve James' excellent answer:

It's better to put BINARY in front of the constant instead:

SELECT * FROM `table` WHERE `column` = BINARY 'value'

Putting BINARY in front of column will prevent the use of any index on that column.

Thanks guys for help, here is the code I tried which is working for me

   UILabel *instructions = [[UILabel alloc]initWithFrame:CGRectMake(10, 225, 300, 180)];
   NSString *text = @"First take clear picture and then try to zoom in to fit the ";
   instructions.text = text;
   instructions.textAlignment = UITextAlignmentCenter;
   instructions.lineBreakMode = NSLineBreakByWordWrapping;
   [instructions setTextColor:[UIColor grayColor]];

   CGSize expectedLabelSize = [text sizeWithFont:instructions.font 
                                constrainedToSize:instructions.frame.size
                                    lineBreakMode:UILineBreakModeWordWrap];

    CGRect newFrame = instructions.frame;
    newFrame.size.height = expectedLabelSize.height;
    instructions.frame = newFrame;
    instructions.numberOfLines = 0;
    [instructions sizeToFit];
    [self addSubview:instructions];

You can also do something like this...

<input @input="myHandler('foo', 'bar', ...arguments)">

Evan You himself recommended this technique in one post on Vue forum. In general some events may emit more than one argument. Also as documentation states internal variable $event is meant for passing original DOM event.

It's \n. When you're reading or writing text mode files, or to stdin/stdout etc, you must use \n, and C will handle the translation for you. When you're dealing with binary files, by definition you are on your own.

loadXMLDoc JS function should return false, otherwise it will result in postback.

You could do this using SUMIF. This allows you to SUM a value in a cell IF a value in another cell meets the specified criteria. Here's an example:

 -   A         B
 1   100       YES
 2   100       YES
 3   100       NO

Using the formula: =SUMIF(B1:B3, "YES", A1:A3), you will get the result of 200.

Here's a screenshot of a working example I just did in Excel:

Well the closest thing I've been able to get with the StyledMarker is this.

The bullet in the middle isn't quite a big as the default one though. The StyledMarker class simply builds this url and asks the google api to create the marker.

From the class use example use "%E2%80%A2" as your text, as in:

var styleMaker2 = new StyledMarker({styleIcon:new StyledIcon(StyledIconTypes.MARKER,{text:"%E2%80%A2"},styleIconClass),position:new google.maps.LatLng(37.263477473067, -121.880502070713),map:map});

You will need to modifiy StyledMarker.js to comment out the lines:

  if (text_) {
    text_ = text_.substr(0,2);
  }

as this will trim the text string to 2 characters.

Alternatively you could create custom marker images based on the default one with the colors you desire and override the default marker with code such as this:

marker = new google.maps.Marker({
  map:map,
  position: latlng,
  icon: new google.maps.MarkerImage(
    'http://www.gettyicons.com/free-icons/108/gis-gps/png/24/needle_left_yellow_2_24.png',
    new google.maps.Size(24, 24),
    new google.maps.Point(0, 0),
    new google.maps.Point(0, 24)
  )
});

With latest version of windows (e.g. Windows 10, other servers), type/search for "Developers Command prompt.." It will pop up the relevant command prompt for the Visual Studio version.

e.g. Developer Command Prompt for VS 2015

Would Activity.onWindowFocusChanged(boolean hasFocus) be useful here? That, plus a class-level flag, something like isFocused that onWindowFocusChanged sets, would be an easy way to tell at any point in your activity if it is focused or not. From reading the docs, it looks like it would properly set "false" in any situation where the activity isn't directly in the physical "foreground", like if a dialog is being displayed or the notification tray is pulled down.

Example:

boolean isFocused;
@Override
void onWindowFocusChanged (boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    isFocused = hasFocus;
}

void someMethod() {
    if (isFocused) {
        // The activity is the foremost object on the screen
    } else {
        // The activity is obscured or otherwise not visible
    }
}

you can insert using loop if you want to insert some random values.

BEGIN 
    FOR x IN 1 .. 1000 LOOP
         INSERT INTO MULTI_INSERT_DEMO (ID, NAME)
         SELECT x, 'anyName' FROM dual;
    END LOOP;
END;

if you want page numbering:

Example: 1 2 3 4...

HTML:

<div class="slider">
  <div>
    <div>Some content</div>
    <div class="slider-number"><span>1 2 3 4...</span></div>
  </div>
  <div>
    <div>Some content</div>
    <div class="slider-number"><span>1 2 3 4...</span></div>
  </div>
  ...
  ...
</div>

JS:

$('.slider').on('init reInit afterChange',
    function(event, slick, currentSlide){
        var status = $(this).find('.slider-number span');
        //currentSlide is undefined on init -- set it to 0 in this case (currentSlide is 0 based)
        var i = slick.currentSlide;
        var slidesLength = slick.slideCount;
        var numberSlide1 = i + 1 <= slidesLength ? i + 1 : i - (slidesLength - 1);
        var numberSlide2 = i + 2 <= slidesLength ? i + 2 : i - (slidesLength - 2);
        var numberSlide3 = i + 3 <= slidesLength ? i + 3 : i - (slidesLength - 3);
        var numberSlide4 = i + 4 <= slidesLength ? i + 4 : i - (slidesLength - 4);

        status.html('<strong>'+numberSlide1+'</strong>' + ' ' +
            numberSlide2 + ' ' +
            numberSlide3 + ' ' +
            numberSlide4 + '...');
});

How about making your app agnostic of the server's timezone?

Owing to any of these possible scenarios:

• You might not have control over the web/database server's timezone settings
• You might mess up and set the settings incorrectly
• There are so many settings as described in the other answers, and so many things to keep track of, that you might miss something
• An update on the server, or a software reset, or another admin, might unknowing reset the servers' timezone to the default - thus breaking your application

All of the above scenarios give rise to breaking of your application's time calculations. Thus it appears that the better approach is to make your application work independent of the server's timezone.

The idea is simply to always create dates in UTC before storing them into the database, and always re-create them from the stored values in UTC as well. This way, the time calculations won't ever be incorrect, because they're always in UTC. This can be achieved by explicity stating the DateTimeZone parameter when creating a PHP DateTime object.

On the other hand, the client side functionality can be configured to convert all dates/times received from the server to the client's timezone. Libraries like moment.js make this super easy to do.

For example, when storing a date in the database, instead of using the NOW() function of MySQL, create the timestamp string in UTC as follows:

// Storing dates
$date = new DateTime('now', new DateTimeZone('UTC'));
$sql = 'insert into table_name (date_column) values ("' . $date . '")';

// Retreiving dates
$sql = 'select date_column from table_name where condition';
$dateInUTC = new DateTime($date_string_from_db, new DateTimeZone('UTC'));

You can set the default timezone in PHP for all dates created, thus eliminating the need to initialize the DateTimeZone class every time you want to create a date.

Usually, git creates a hidden directory in project's root directory (.git/)

When you're working on a CMS, its possible you install modules/plugins carrying .git/ directory with git's metadata for the specific module/plugin

Quickest solution is to find all .git directories and keep only your root git metadata directory. If you do so, git will not consider those modules as project submodules.

I had a similar issue, but had painted myself into a corner with GUI tools.

I had a subproject with a few files in it that I had so far just copied around instead of checking into their own git repo. I created a repo in the subfolder, was able to commit, push, etc just fine. But in the parent repo the subfolder wasn't treated as a submodule, and its files were still being tracked by the parent repo - no good.

To get out of this mess I had to tell Git to stop tracking the subfolder (without deleting the files):

proj> git rm -r --cached ./ui/jslib

Then I had to tell it there was a submodule there (which you can't do if anything there is currently being tracked by git):

proj> git submodule add ./ui/jslib

Update

The ideal way to handle this involves a couple more steps. Ideally, the existing repo is moved out to its own directory, free of any parent git modules, committed and pushed, and then added as a submodule like:

proj> git submodule add [email protected]:user/jslib.git ui/jslib

That will clone the git repo in as a submodule - which involves the standard cloning steps, but also several other more obscure config steps that git takes on your behalf to get that submodule to work. The most important difference is that it places a simple .git file there, instead of a .git directory, which contains a path reference to where the real git dir lives - generally at parent project root .git/modules/jslib.

If you don't do things this way they'll work fine for you, but as soon as you commit and push the parent, and another dev goes to pull that parent, you just made their life a lot harder. It will be very difficult for them to replicate the structure you have on your machine so long as you have a full .git dir in a subfolder of a dir that contains its own .git dir.

So, move, push, git add submodule, is the cleanest option.

You can do that using three ways first use if condition like below

{!! $text !!}

The is Second way

<td class="nowrap">
@if( $order->status == '0' )
    <button class="btn btn-danger">Inactive</button>
@else
    <button class="btn btn-success">Active</button>
@endif
</td>

The third and proper way for use ternary operator on blade

<td class="nowrap">
      {!! $order->status=='0' ? 
          '<button class="btn btn-danger">Inactive</button> : 
          '<button class="btn btn-success">Active</button> !!}
</td>

I hope the third way is perfect for used ternary operator on blade.

You can also use the svnadmin hotcopy command:

svnadmin hotcopy OLD_REPOS_PATH NEW_REPOS_PATH

It takes a full backup from repository, including all hooks, configuration files, etc.

If SQL Server hasn't been restarted (and the plan hasn't been evicted, etc.), you may be able to find the query in the plan cache.

SELECT t.[text]
FROM sys.dm_exec_cached_plans AS p
CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t
WHERE t.[text] LIKE N'%something unique about your query%';

If you lost the file because Management Studio crashed, you might be able to find recovery files here:

C:\Users\<you>\Documents\SQL Server Management Studio\Backup Files\

Otherwise you'll need to use something else going forward to help you save your query history, like SSMS Tools Pack as mentioned in Ed Harper's answer - though it isn't free in SQL Server 2012+. Or you can set up some lightweight tracing filtered on your login or host name (but please use a server-side trace, not Profiler, for this).

As @Nenad-Zivkovic commented, it might be helpful to join on sys.dm_exec_query_stats and order by last_execution_time:

SELECT t.[text], s.last_execution_time
FROM sys.dm_exec_cached_plans AS p
INNER JOIN sys.dm_exec_query_stats AS s
   ON p.plan_handle = s.plan_handle
CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t
WHERE t.[text] LIKE N'%something unique about your query%'
ORDER BY s.last_execution_time DESC;

The isdigit method of the str type returns True iff the given string is nothing but one or more digits. If it's not, you know the string should be treated as just a string.

It looks like in one of last c++ boost version appeared library to provide exactly what You want, probably the code would be multiplatform. It is boost::stacktrace, which You can use like as in boost sample:

#include <filesystem>
#include <sstream>
#include <fstream>
#include <signal.h>     // ::signal, ::raise
#include <boost/stacktrace.hpp>

const char* backtraceFileName = "./backtraceFile.dump";

void signalHandler(int)
{
    ::signal(SIGSEGV, SIG_DFL);
    ::signal(SIGABRT, SIG_DFL);
    boost::stacktrace::safe_dump_to(backtraceFileName);
    ::raise(SIGABRT);
}

void sendReport()
{
    if (std::filesystem::exists(backtraceFileName))
    {
        std::ifstream file(backtraceFileName);

        auto st = boost::stacktrace::stacktrace::from_dump(file);
        std::ostringstream backtraceStream;
        backtraceStream << st << std::endl;

        // sending the code from st

        file.close();
        std::filesystem::remove(backtraceFileName);
    }
}

int main()
{
    ::signal(SIGSEGV, signalHandler);
    ::signal(SIGABRT, signalHandler);

    sendReport();
    // ... rest of code
}

In Linux You compile the code above:

g++ --std=c++17 file.cpp -lstdc++fs -lboost_stacktrace_backtrace -ldl -lbacktrace

Example backtrace copied from boost documentation:

0# bar(int) at /path/to/source/file.cpp:70
1# bar(int) at /path/to/source/file.cpp:70
2# bar(int) at /path/to/source/file.cpp:70
3# bar(int) at /path/to/source/file.cpp:70
4# main at /path/to/main.cpp:93
5# __libc_start_main in /lib/x86_64-linux-gnu/libc.so.6
6# _start

Try this: add white-space: normal; to the style definition of the Bootstrap Button or you can replace the code you displayed with the one below

<div class="col-lg-3"> <!-- FIRST COL -->
  <div class="panel panel-default">
    <div class="panel-body">

I have updated your fiddle here to show how it comes out.

The other people made very nice answers, but I would like to complete their work with an extra development tool. It is called Live HTTP Headers and you can install it into your Firefox, and in Chrome we have the same plug in like this.

Working with it is queit easy.

1. Using your Firefox, navigate to the website which you want to get your post request to it.

2. In your Firefox menu Tools->Live Http Headers

3. A new window pop ups for you, and all the http method details would be saved in this window for you. You don't need to do anything in this step.

4. In the website, do an activity(log in, submit a form, etc.)

5. Look at your plug in window. It is all recorded.

Just remember you need to check the Capture.

List<Card> list = new ArrayList<Card>(Arrays.asList(hand));

DataTable dtbs = new DataTable(); 
DataView dvbs = new DataView(dt); 
dvbs.RowFilter = "ColumnName='Filtervalue'"; 
dtbs = dvbs.ToTable();

As @Raf Z commented on this question, dplyr now has mutate_if. Super useful, simple and readable.

> str(df)
'data.frame':   5 obs. of  5 variables:
 $ A: Factor w/ 5 levels "A","B","C","D",..: 1 2 3 4 5
 $ B: int  1 2 3 4 5
 $ C: logi  TRUE TRUE FALSE FALSE TRUE
 $ D: chr  "a" "b" "c" "d" ...
 $ E: chr  "A a" "B b" "C c" "D d" ...

> df <- df %>% mutate_if(is.character,as.factor)

> str(df)
'data.frame':   5 obs. of  5 variables:
 $ A: Factor w/ 5 levels "A","B","C","D",..: 1 2 3 4 5
 $ B: int  1 2 3 4 5
 $ C: logi  TRUE TRUE FALSE FALSE TRUE
 $ D: Factor w/ 5 levels "a","b","c","d",..: 1 2 3 4 5
 $ E: Factor w/ 5 levels "A a","B b","C c",..: 1 2 3 4 5

If a class defines virtual methods outside that class, then g++ generates the vtable only in the object file that contains the outside-of-class definition of the virtual method that was declared first:

//test.h
struct str
{
   virtual void f();
   virtual void g();
};

//test1.cpp
#include "test.h"
void str::f(){}

//test2.cpp
#include "test.h"
void str::g(){}

The vtable will be in test1.o, but not in test2.o

This is an optimisation g++ implements to avoid having to compile in-class-defined virtual methods that would get pulled in by the vtable.

The link error you describe suggests that the definition of a virtual method (str::f in the example above) is missing in your project.

Bootstrap 4.x with 3 different way.

1. Icon with default bootstrap Style

   <div class="input-group">

If you don't know how many columns you are going to have, the declaration

table-layout: fixed

along with not setting any column widths, would imply that browsers divide the total width evenly - no matter what.

That can also be the problem with this approach, if you use this, you should also consider how overflow is to be handled.

There isn't really a "private method" in Objective-C, if the runtime can work out which implementation to use it will do it. But that's not to say that there aren't methods which aren't part of the documented interface. For those methods I think that a category is fine. Rather than putting the @interface at the top of the .m file like your point 2, I'd put it into its own .h file. A convention I follow (and have seen elsewhere, I think it's an Apple convention as Xcode now gives automatic support for it) is to name such a file after its class and category with a + separating them, so @interface GLObject (PrivateMethods) can be found in GLObject+PrivateMethods.h. The reason for providing the header file is so that you can import it in your unit test classes :-).

By the way, as far as implementing/defining methods near the end of the .m file is concerned, you can do that with a category by implementing the category at the bottom of the .m file:

@implementation GLObject(PrivateMethods)
- (void)secretFeature;
@end

or with a class extension (the thing you call an "empty category"), just define those methods last. Objective-C methods can be defined and used in any order in the implementation, so there's nothing to stop you putting the "private" methods at the end of the file.

Even with class extensions I will often create a separate header (GLObject+Extension.h) so that I can use those methods if required, mimicking "friend" or "protected" visibility.

Since this answer was originally written, the clang compiler has started doing two passes for Objective-C methods. This means you can avoid declaring your "private" methods completely, and whether they're above or below the calling site they'll be found by the compiler.

Andrew had a great response but I wanted to tweek it a little. The way this is different is that I like my ModelViews to not have overhead data in them. Just the data for the object. It seem that ViewData fits the bill for over head data, but of course I'm new at this. I suggest doing something like this.

Controller

virtual public ActionResult DisplaySomeWidget(int id)
{
    SomeModelView returnData = someDataMapper.getbyid(1);
    var serializer = new JavaScriptSerializer();
    ViewData["JSON"] = serializer.Serialize(returnData);
    return View(myview, returnData);
}

View

//create base js object;
var myWidget= new Widget(); //Widget is a class with a public member variable called data.
myWidget.data= <%= ViewData["JSON"] %>;

What This does for you is it gives you the same data in your JSON as in your ModelView so you can potentially return the JSON back to your controller and it would have all the parts. This is similar to just requesting it via a JSONRequest however it requires one less call so it saves you that overhead. BTW this is funky for Dates but that seems like another thread.

Using printf you can do

printf("Here are the first 8 chars: %.8s\n", "A string that is more than 8 chars");

If you're using C++, you can achieve the same result using the STL:

using namespace std; // for clarity
string s("A string that is more than 8 chars");
cout << "Here are the first 8 chars: ";
copy(s.begin(), s.begin() + 8, ostream_iterator<char>(cout));
cout << endl;

Or, less efficiently:

cout << "Here are the first 8 chars: " <<
        string(s.begin(), s.begin() + 8) << endl;

In your androidmanifest.xml file:

   <activity android:name="MainActivity" android:configChanges="keyboardHidden|orientation">

or

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

If you have Oracle 10g, REGEXP_REPLACE is pretty flexible.

Using the following string as a test:

chr(9) || 'Q   qwer' || chr(9) || chr(10) ||
chr(13) || 'qwerqwer     qwerty' || chr(9) || 
chr(10) || chr(13)

The [[:space:]] will remove all whitespace, and the ([[:cntrl:]])|(^\t) regexp will remove non-printing characters and tabs.

select
    tester,
    regexp_replace(tester, '(^[[:space:]]+)|([[:space:]]+$)',null)
            regexp_tester_1,
    regexp_replace(tester, '(^[[:cntrl:]^\t]+)|([[:cntrl:]^\t]+$)',null) 
            regexp_tester_2
from
    (
    select
        chr(9) || 'Q   qwer' || chr(9) || chr(10) ||
                chr(13) || 'qwerqwer     qwerty' || chr(9) || 
                chr(10) || chr(13) tester 
    from 
        dual
    )

Returning:

• REGEXP_TESTER_1: "Qqwerqwerqwerqwerty"
• REGEXP_TESTER_2: "Q qwerqwerqwer qwerty"

Hope this is of some use.

You can try : go to edit>preferencec>type.. select type > choose text engine options select east asian. Restart photoshop. Create new peroject. Try text tool again.

(if you want to use your project created with other text engine type) copy /paste all layers to new project.

This will work:

$email_to = "[email protected],[email protected],[email protected]";

C# in .NET 3.5 using System.DirectoryServices.AccountManagement.

 bool valid = false;
 using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
 {
     valid = context.ValidateCredentials( username, password );
 }

This will validate against the current domain. Check out the parameterized PrincipalContext constructor for other options.

It tells the compiler that you're in a Single Thread Apartment model. This is an evil COM thing, it's usually used for Windows Forms (GUI's) as that uses Win32 for its drawing, which is implemented as STA. If you are using something that's STA model from multiple threads then you get corrupted objects.

This is why you have to invoke onto the Gui from another thread (if you've done any forms coding).

Basically don't worry about it, just accept that Windows GUI threads must be marked as STA otherwise weird stuff happens.

Using LATEST Bootstrap 4.5+

• Use the same modal repeatedly by passing different Youtube URL's from the HTML Page
• With a great Play button icon and Autoplay enabled
• Just COPY the code and you are all SET!!!
• View solution in Codepen

$(".video-link").click(function () {
  var theModal = $(this).data("target");
  videoSRC = $(this).attr("data-video");
  videoSRCauto = videoSRC + "?modestbranding=1&rel=0&showinfo=0&html5=1&autoplay=1";
  $(theModal + ' iframe').attr('src', videoSRCauto);
  $(theModal + ' button.close').click(function () {
    $(theModal + ' iframe').attr('src', videoSRC);

The following code will set the media stream volume to max:

AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamVolume(AudioManager.STREAM_MUSIC,
    audioManager.getStreamMaxVolume(AudioManager.STREAM_MUSIC),
    AudioManager.FLAG_SHOW_UI);

Here's an example:

  private static final HashMap<String, String> MAP = new HashMap<String, String>();
  static {
    MAP.put("banana", "honey");
    MAP.put("peanut butter", "jelly");
    MAP.put("rice", "beans");
  }

The code in the "static" section(s) will be executed at class load time, before any instances of the class are constructed (and before any static methods are called from elsewhere). That way you can make sure that the class resources are all ready to use.

It's also possible to have non-static initializer blocks. Those act like extensions to the set of constructor methods defined for the class. They look just like static initializer blocks, except the keyword "static" is left off.

I had the same issue, to resolve it I added the following line to my.ini

innodb_force_recovery = 1

I was having this exact same problem and the solution turned out to be pretty easy for me. Basically change your code to the following and it should work. NOTE: the return before gulp.src made all the difference for me.

gulp.task "coffee", ->
    return gulp.src("src/server/**/*.coffee")
        .pipe(coffee {bare: true}).on("error",gutil.log)
        .pipe(gulp.dest "bin")

gulp.task "clean",->
    return gulp.src("bin", {read:false})
        .pipe clean
            force:true

gulp.task 'develop',['clean','coffee'], ->
    console.log "run something else"

If you're using Visual Studio 2012 or older, use the getch() function, if you are using Visual Studio 2013 or newer, use _getch(). You will have to use #include <conio.h>. Example:

#include <iostream>
#include <conio.h>

int main()
{
   std::cout << "Press any key to continue. . .\n";
   _getch(); //Or getch()
}

Use $event.stopPropagation():

<div ng-controller="OverlayCtrl" class="overlay" ng-click="hideOverlay()">
    <img src="http://some_src" ng-click="nextImage(); $event.stopPropagation()" />
</div>

Here's a demo: http://plnkr.co/edit/3Pp3NFbGxy30srl8OBmQ?p=preview

There are three types of variables:

• Instance variables: are always initialized
• Static variables: are always initialized
• Local variables: must be initialized before use

The default values for instance and static variables are the same and depends on the type:

• Object type (String, Integer, Boolean and others): initialized with null
• Primitive types:
  • byte, short, int, long: 0
  • float, double: 0.0
  • boolean: false
  • char: '\u0000'

An array is an Object. So an array instance variable that is declared but no explicitly initialized will have null value. If you declare an int[] array as instance variable it will have the null value.

Once the array is created all of its elements are assiged with the default type value. For example:

private boolean[] list; // default value is null

private Boolean[] list; // default value is null

once is initialized:

private boolean[] list = new boolean[10]; // all ten elements are assigned to false

private Boolean[] list = new Boolean[10]; // all ten elements are assigned to null (default Object/Boolean value)

Why don't you simply use JavaScript's trim():

str.trim() //Will work everywhere irrespective of any framework.

For compatibility with <IE9 use:

if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, ''); 
  }
}

Change your onCreateOptionsMenu method to return true. To quote the docs:

You must return true for the menu to be displayed; if you return false it will not be shown.

$objPHPExcel
    ->getActiveSheet()
    ->getStyle('A1')
    ->getFill()
    ->getStartColor()
    ->getRGB();

There is nothing you can do on your end (client side). You can not enable crossDomain calls yourself, the source (dailymotion.com) needs to have CORS enabled for this to work.

The only thing you can really do is to create a server side proxy script which does this for you. Are you using any server side scripts in your project? PHP, Python, ASP.NET etc? If so, you could create a server side "proxy" script which makes the HTTP call to dailymotion and returns the response. Then you call that script from your Javascript code, since that server side script is on the same domain as your script code, CORS will not be a problem.

Git 101:

git is a decentralized version control system. You do not necessary need a server to get up and running with git. Still you might want to do that as it looks cool, right? (It's also useful if you want to work on a single project from multiple computers.)

So to get a "server" running you need to run git init --bare <your_project>.git as this will create an empty repository, which you can then import on your machines without having to muck around in config files in your .git dir.

After this you could clone the repo on your clients as it is supposed to work, but I found that some clients (namely git-gui) will fail to clone a repo that is completely empty. To work around this you need to run cd <your_project>.git && touch <some_random_file> && git add <some_random_file> && git commit && git push origin master. (Note that you might need to configure your username and email for that machine's git if you hadn't done so in the past. The actual commands to run will be in the error message you get so I'll just omit them.)

So at this point you can clone the repository to any machine simply by running git clone <user>@<server>:<relative_path><your_project>.git. (As others have pointed out you might need to prefix it with ssh:// if you use the absolute path.) This assumes that you can already log in from your client to the server. (You'll also get bonus points for setting up a config file and keys for ssh, if you intend to push a lot of stuff to the remote server.)

This pretty much tells you what you need to know.
And this is for those who know the basic workings of git but sometimes forget the exact syntax.

With postgres, I had to adjust the solution with this to work for me:

UPDATE BookingPitches AS p
SET extrasPrice = t.sumPrice
FROM 
    (
        SELECT PitchID, SUM(Price) sumPrice
        FROM BookingPitchExtras
        WHERE [required] = 1
        GROUP BY PitchID 
    ) t
WHERE t.PitchID = p.ID AND p.bookingID = 1

I made a annotation library that can do the cast for you. check this out. https://github.com/zeroarst/callbackfragment/

@CallbackFragment
public class MyFragment extends Fragment {

    @Callback
    interface FragmentCallback {
       void onClickButton(MyFragment fragment);
    }    
    private FragmentCallback mCallback;

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.bt1
                mCallback.onClickButton(this);
                break;
            case R.id.bt2
                // Because we give mandatory = false so this might be null if not implemented by the host.
                if (mCallbackNotForce != null)
                mCallbackNotForce.onClickButton(this);
                break;
        }
    }
}

It then generates a subclass of your fragment. And just add it to FragmentManager.

public class MainActivity extends AppCompatActivity implements MyFragment.FragmentCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        getSupportFragmentManager().beginTransaction()
            .add(R.id.lo_fragm_container, MyFragmentCallbackable.create(), "MY_FRAGM")
            .commit();
    }

    Toast mToast;

    @Override
    public void onClickButton(MyFragment fragment) {
        if (mToast != null)
            mToast.cancel();
        mToast = Toast.makeText(this, "Callback from " + fragment.getTag(), Toast.LENGTH_SHORT);
        mToast.show();
    }
}

UPDATE : check Peter's answer below for a builtin solution :

This is a helper to set a persistent cookie:

import datetime

def set_cookie(response, key, value, days_expire=7):
    if days_expire is None:
        max_age = 365 * 24 * 60 * 60  # one year
    else:
        max_age = days_expire * 24 * 60 * 60
    expires = datetime.datetime.strftime(
        datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age),
        "%a, %d-%b-%Y %H:%M:%S GMT",
    )
    response.set_cookie(
        key,
        value,
        max_age=max_age,
        expires=expires,
        domain=settings.SESSION_COOKIE_DOMAIN,
        secure=settings.SESSION_COOKIE_SECURE or None,
    )

Use the following code before sending a response.

def view(request):
    response = HttpResponse("hello")
    set_cookie(response, 'name', 'jujule')
    return response

You can try my function for merging images horizontally or vertically without changing image ratio. just copy paste will work.

I got similar error when i run legacy application in Visual studio 2013 iis express and solved the issue by following steps 1.Navigate to "Documents\IISExpress\config" 2.Open "applicationhost.config" using notepad or any preferred editor 3.scroll down and find for section name="anonymousAuthentication" under 4. Update overrideModeDefault="Deny" to "Allow" 5. save the config file 6. Run the legacy application and worked fine for me.
