You're getting errors because you're attempting to read post variables that haven't been set, they only get set on form submission. Wrap your php code at the bottom in an

if ($_SERVER['REQUEST_METHOD'] === 'POST') { ... }

Also, your code is ripe for SQL injection. At the very least use mysql_real_escape_string on the post vars before using them in SQL queries. mysql_real_escape_string is not good enough for a production site, but should score you extra points in class.

If You want to ensure, that your code is running with python2 and python3, use function input () in your script and add this to begin of your script:

from sys import version_info
if version_info.major == 3:
    pass
elif version_info.major == 2:
    try:
        input = raw_input
    except NameError:
        pass
else:
    print ("Unknown python version - input function not safe")

Just check JSON option from the drop down next to binary; when you click raw. This should do

Or maybe

 background: transparent !important;
 color: #ffffff;

1. Open firebase, select database on the left hand side.
2. Now on the right hand side, select [Realtime database] from the drown and change the rules to:

{
  "rules": {
    ".read": true,
    ".write": true
  }
}

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {res.EMAIL, res.USERNAME} );

OR you can use

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {email=res.EMAIL, username=res.USERNAME} );

Explanation :

1. Select employee from the db as res.

2. Filter the employee details as per the where condition.

3. Select required fields from the employee object by creating an Anonymous object using new { }

The OP did not exclude the starting variable, so for completeness here is how to handle the generic case of processing a supposed dictionary that may include items as dictionaries.

Also following the pure Python(3.8) recommended way to test for dictionary in the above comments.

from collections.abc import Mapping

dict = {'abc': 'abc', 'def': {'ghi': 'ghi', 'jkl': 'jkl'}}

def parse_dict(in_dict): 
    if isinstance(in_dict, Mapping):
        for k_outer, v_outer in in_dict.items():
            if isinstance(v_outer, Mapping):
                for k_inner, v_inner in v_outer.items():
                    print(k_inner, v_inner)
            else:
                print(k_outer, v_outer)

parse_dict(dict)

You can use UITableViewRowAction's backgroundColor to set custom image or view. The trick is using UIColor(patternImage:).

Basically the width of UITableViewRowAction area is decided by its title, so you can find a exact length of title(or whitespace) and set the exact size of image with patternImage.

To implement this, I made a UIView's extension method.

func image() -> UIImage {
    UIGraphicsBeginImageContextWithOptions(bounds.size, isOpaque, 0)
    guard let context = UIGraphicsGetCurrentContext() else {
        return UIImage()
    }
    layer.render(in: context)
    let image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image!
}

and to make a string with whitespace and exact length,

fileprivate func whitespaceString(font: UIFont = UIFont.systemFont(ofSize: 15), width: CGFloat) -> String {
    let kPadding: CGFloat = 20
    let mutable = NSMutableString(string: "")
    let attribute = [NSFontAttributeName: font]
    while mutable.size(attributes: attribute).width < width - (2 * kPadding) {
        mutable.append(" ")
    }
    return mutable as String
}

and now, you can create UITableViewRowAction.

func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
    let whitespace = whitespaceString(width: kCellActionWidth)
    let deleteAction = UITableViewRowAction(style: .`default`, title: whitespace) { (action, indexPath) in
        // do whatever you want
    }

    // create a color from patter image and set the color as a background color of action
    let kActionImageSize: CGFloat = 34
    let view = UIView(frame: CGRect(x: 0, y: 0, width: kCellActionWidth, height: kCellHeight))
    view.backgroundColor = UIColor.white
    let imageView = UIImageView(frame: CGRect(x: (kCellActionWidth - kActionImageSize) / 2,
                                              y: (kCellHeight - kActionImageSize) / 2,
                                              width: 34,
                                              height: 34))
    imageView.image = UIImage(named: "x")
    view.addSubview(imageView)
    let image = view.image()

    deleteAction.backgroundColor = UIColor(patternImage: image)

    return [deleteAction]
}

The result will look like this.

Another way to do this is to import custom font which has the image you want to use as a font and use UIButton.appearance. However this will affect other buttons unless you manually set other button's font.

From iOS 11, it will show this message [TableView] Setting a pattern color as backgroundColor of UITableViewRowAction is no longer supported.. Currently it is still working, but it wouldn't work in the future update.

==========================================

For iOS 11+, you can use:

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
  let deleteAction = UIContextualAction(style: .normal, title: "Delete") { (action, view, completion) in
    // Perform your action here
      completion(true)
  }

  let muteAction = UIContextualAction(style: .normal, title: "Mute") { (action, view, completion) in
    // Perform your action here
    completion(true)
  }

  deleteAction.image = UIImage(named: "icon.png")
  deleteAction.backgroundColor = UIColor.red
  return UISwipeActionsConfiguration(actions: [deleteAction, muteAction])
} 

import base64
from PIL import Image
from io import BytesIO

with open("image.jpg", "rb") as image_file:
    data = base64.b64encode(image_file.read())

im = Image.open(BytesIO(base64.b64decode(data)))
im.save('image1.png', 'PNG')

Maybe Skype or other Application is using port 80. This you can check in

Tools->Settings->Advanced->Connection

This would also work: hash[hey] = nil

git add -A
git diff HEAD

Generate patch if required, and then:

git reset HEAD

$('elemId').length doesn't work for me.

You need to put # before element id:

$('#elemId').length
---^

With vanilla JavaScript, you don't need the hash (#) e.g. document.getElementById('id_here') , however when using jQuery, you do need to put hash to target elements based on id just like CSS.

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

The sample mvcmusicstore.codeplex.com opened in vs2015 missed some references, one of them System.web.mvc.

The fix for this was to remove it from the references and to add a reference: choose Extentions under Assemblies, there you can find and add System.Web.Mvc.

(The other assemblies I added with the nuget packages.)

Although there are already a lot of good answers to this question, I came up with another solution that I think is more simple. Surround your query with a try block and the following catch:

catch (SQLiteException e){
    if (e.getMessage().contains("no such table")){
            Log.e(TAG, "Creating table " + TABLE_NAME + "because it doesn't exist!" );
            // create table
            // re-run query, etc.
    }
}

It worked for me!

In Angular4 as you deal with @types system, you should do following things,

Do,

1) npm install --save @types/jquery
2) npm install --save @types/bootstrap

tsconfig.json

look for types array and add jquery and bootstrap entries,

"types": [
      "jquery",
      "bootstrap",  
      "node"
]

Index.html

in head section add following entries,

  <link href="node_modules/bootstrap/dist/css/bootstrap.min.css" rel="stylesheet">
  <script src="node_modules/jquery/dist/jquery.min.js "></script>
  <script src="node_modules/bootstrap/dist/js/bootstrap.js "></script>

And start using jquery and bootstrap both.

With reference to man ssh-keygen, the length of a DSA key is restricted to exactly 1024 bit to remain compliant with NIST's FIPS 186-2. Nonetheless, longer DSA keys are theoretically possible; FIPS 186-3 explicitly allows them. Furthermore, security is no longer guaranteed with 1024 bit long RSA or DSA keys.

In conclusion, a 2048 bit RSA key is currently the best choice.

MORE PRECAUTIONS TO TAKE

Establishing a secure SSH connection entails more than selecting safe encryption key pair technology. In view of Edward Snowden's NSA revelations, one has to be even more vigilant than what previously was deemed sufficient.

To name just one example, using a safe key exchange algorithm is equally important. Here is a nice overview of current best SSH hardening practices.

Sub Macro1()
    Dim StartTime As Double
    StartTime = Timer

        ''''''''''''''''''''
            'Your Code'
        ''''''''''''''''''''
    MsgBox "RunTime : " & Format((Timer - StartTime) / 86400, "hh:mm:ss")
End Sub

Output:

RunTime : 00:00:02

public IList<Splitting> get(Guid companyId, long customrId) {    
    var res=from c in Customers_data_source
            where c.CustomerId = customrId && c.CompanyID == companyId
            from s in Splittings_data_srouce
            where s.CustomerID = c.CustomerID
            select s;

    return res.ToList();
}

I built a tool for meta generation. It pre-configures entries for Facebook, Google+ and Twitter, and you can use it free here: http://www.groovymeta.com

To answer the question a bit more, OG tags (Open Graph) tags work similarly to meta tags, and should be placed in the HEAD section of your HTML file. See Facebook's best practises for more information on how to use OG tags effectively.

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

One of the pitfalls as I know is IE problem with custom elements. As quoted from the docs:

3) you do not use custom element tags such as (use the attribute version instead)

4) if you do use custom element tags, then you must take these steps to make IE 8 and below happy

<!doctype html>
  <html xmlns:ng="http://angularjs.org" id="ng-app" ng-app="optionalModuleName">
    <head>
      <!--[if lte IE 8]>
        <script>
          document.createElement('ng-include');
          document.createElement('ng-pluralize');
          document.createElement('ng-view');

          // Optionally these for CSS
          document.createElement('ng:include');
          document.createElement('ng:pluralize');
          document.createElement('ng:view');
        </script>
      <![endif]-->
    </head>
    <body>
      ...
    </body>
  </html>

Try this, definitely works for Swift 2.0

 let player = AVPlayer(URL: url)
    let playerController = AVPlayerViewController()

    playerController.player = player
    self.addChildViewController(playerController)
    self.view.addSubview(playerController.view)
    playerController.view.frame = self.view.frame

    player.play()  

HTTP does not place a predefined limit on the length of each header field or on the length of the header section as a whole, as described in Section 2.5. Various ad hoc limitations on individual header field length are found in practice, often depending on the specific field semantics.

HTTP Header values are restricted by server implementations. Http specification doesn't restrict header size.

A server that receives a request header field, or set of fields, larger than it wishes to process MUST respond with an appropriate 4xx (Client Error) status code. Ignoring such header fields would increase the server's vulnerability to request smuggling attacks (Section 9.5).

Most servers will return 413 Entity Too Large or appropriate 4xx error when this happens.

A client MAY discard or truncate received header fields that are larger than the client wishes to process if the field semantics are such that the dropped value(s) can be safely ignored without changing the message framing or response semantics.

Uncapped HTTP header size keeps the server exposed to attacks and can bring down its capacity to serve organic traffic.

The statement icr=y; does not make the reference refer to y; it assigns the value of y to the variable that icr refers to, i.

References are inherently const, that is you can't change what they refer to. There are 'const references' which are really 'references to const', that is you can't change the value of the object they refer to. They are declared const int& or int const& rather than int& const though.

I think the easiest way in the latest Android versions is by going to Design mode of an XML (not Text).

Then from the menu, select option - Create Landscape Variation. This will create a landscape xml without any hassle in a few seconds. The latest Android Studio version allows you to create a landscape view right away.

I hope this works for you.

{
    string submitType = "unknown";

    if(collection["submit"] != null)

    }
    else if (collection["process"] != null)
    {
        submitType = "process";
    }

} // End of the index method

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.

Followings gives dimensions as well as channels:

import numpy as np
from PIL import Image

with Image.open(filepath) as img:
    shape = np.array(img).shape

To perform this operation see the next images:

and next step is add *.mdf file,

very important, the .mdf file must be located in C:......\MSSQL12.SQLEXPRESS\MSSQL\DATA

Now remove the log file

If you put the SQL strings in a properties file and then read that in you can keep the SQL strings in a plain text file.

That doesn't solve the SQL type issues, but at least it makes copying&pasting from TOAD or sqlplus much easier.

Here are the basic instructions:-

1. Locate the "server.xml" file in the "conf" folder beneath Tomcat's base directory (i.e. %CATALINA_HOME%/conf/server.xml).
2. Open the file in an editor and search for <Connector.
3. Locate the relevant connector that is timing out - this will typically be the HTTP connector, i.e. the one with protocol="HTTP/1.1".
4. If a connectionTimeout value is set on the connector, it may need to be increased - e.g. from 20000 milliseconds (= 20 seconds) to 120000 milliseconds (= 2 minutes). If no connectionTimeout property value is set on the connector, the default is 60 seconds - if this is insufficient, the property may need to be added.
5. Restart Tomcat

In my case I had to open the file:

C:\...\Documents\IISExpress\config\applicationhost.config

I had this inside the file:

  <authentication>
  <anonymousAuthentication enabled="true" User="" />

I just removed the User="" part. I really don't know how this thing got there... :)

Note: Make sure you have something like this in the end of applicationhost.config:

   .
   .
   .
   <location path="MyCompany.MyProjectName.Web">
        <system.webServer>
            <security>
                <authentication>
                    <anonymousAuthentication enabled="true" />
                    <windowsAuthentication enabled="false" />
                </authentication>
            </security>
        </system.webServer>
    </location>
</configuration>

Now I can access the login page as expected.

Create some public Properties on your sub-form like so

public string ReturnValue1 {get;set;} 
public string ReturnValue2 {get;set;}

then set this inside your sub-form ok button click handler

private void btnOk_Click(object sender,EventArgs e)
{
    this.ReturnValue1 = "Something";
    this.ReturnValue2 = DateTime.Now.ToString(); //example
    this.DialogResult = DialogResult.OK;
    this.Close();
}

Then in your frmHireQuote form, when you open the sub-form

using (var form = new frmImportContact())
{
    var result = form.ShowDialog();
    if (result == DialogResult.OK)
    {
        string val = form.ReturnValue1;            //values preserved after close
        string dateString = form.ReturnValue2;
        //Do something here with these values

        //for example
        this.txtSomething.Text = val;
    }
}

Additionaly if you wish to cancel out of the sub-form you can just add a button to the form and set its DialogResult to Cancel and you can also set the CancelButton property of the form to said button - this will enable the escape key to cancel out of the form.

sysexits.h has a list of standard exit codes. It seems to date back to at least 1993 and some big projects like Postfix use it, so I imagine it's the way to go.

From the OpenBSD man page:

According to style(9), it is not good practice to call exit(3) with arbi- trary values to indicate a failure condition when ending a program. In- stead, the pre-defined exit codes from sysexits should be used, so the caller of the process can get a rough estimation about the failure class without looking up the source code.

I am currently using hooks.
Something like this:

import React, { useEffect } from 'react'


const AppBase = ({ }) => {

    useEffect(() => {
        // set el height and width etc.
    }, [])

    return (
        <div className="wrapper">
            <Sidebar />
            <div className="inner-wrapper">
                <ActionBar title="Title Here" />
                <BalanceBar balance={balance} />
                <div className="app-content">
                    <List items={items} />
                </div>
            </div>
        </div>
    );
}

export default AppBase

I would update the formula in C1. Then copy the formula from C1 and paste it till C10...

Not sure about a more elegant solution

Range("C1").Copy
Range("C1:C10").Pastespecial(XlPasteall)

var page_url = windws.location.href;

    }, 2000)
} else if (page_id == "") {
    $("html, body").animate({
        scrollTop: $("#scroll-" + page_id).offset().top

});

A more general way of achieving column type transformation is as follows:

If you want to transform all your factor columns to character columns, e.g., this can be done using one pipe:

df %>%  mutate_each_( funs(as.character(.)), names( .[,sapply(., is.factor)] ))

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

Additional Version of PHP can be installed directly from the APP (using MAMP PRO v5 at least).

Here's how (All Steps):

Step-by-step screenshots:

there's a bootstrap function to change the color of table header called thead-dark for dark background of table header and thead-light for light background of table header. Your code will look like this after using this function.

    <tr class="thead-danger">
        <!-- here I used dark table headre -->
        <th>
            @Html.DisplayNameFor(model => model.name)

  is a HTML entity. When doing .text(), all HTML entities are decoded to their character values.

Instead of comparing using the entity, compare using the actual raw character:

var x = td.text();
if (x == '\xa0') { // Non-breakable space is char 0xa0 (160 dec)
  x = '';
}

Or you can also create the character from the character code manually it in its Javascript escaped form:

var x = td.text();
if (x == String.fromCharCode(160)) { // Non-breakable space is char 160
  x = '';
}

More information about String.fromCharCode is available here:

fromCharCode - MDC Doc Center

More information about character codes for different charsets are available here:

Windows-1252 Charset
UTF-8 Charset

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

The 'pidof' command will not display pids of shell/perl/python scripts. So to find the process id’s of my Perl script I had to use the -x option i.e. 'pidof -x perlscriptname'

For personal teams

grep DEVELOPMENT_TEAM MyProject.xcodeproj/project.pbxproj

should give you the team ID

You can use the environment variable $HOME for that.

I had this concern when working on a Rails application with Docker.

My most preferred approach is to generally not use quotes. This includes not using quotes for:

• variables like ${RAILS_ENV}
• values separated by a colon (:) like postgres-log:/var/log/postgresql
• other strings values

I, however, use double-quotes for integer values that need to be converted to strings like:

• docker-compose version like version: "3.8"
• port numbers like "8080:8080"

However, for special cases like booleans, floats, integers, and other cases, where using double-quotes for the entry values could be interpreted as strings, please do not use double-quotes.

Here's a sample docker-compose.yml file to explain this concept:

version: "3"

services:
  traefik:
    image: traefik:v2.2.1
    command:
      - --api.insecure=true # Don't do that in production
      - --providers.docker=true
      - --providers.docker.exposedbydefault=false
      - --entrypoints.web.address=:80
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro

That's all.

I hope this helps

AFAIK, HTML5 does not provide an API which supports full screen.

This question has some view points on making html5 video full screen for example using webkitEnterFullscreen in webkit.
Is there a way to make html5 video fullscreen

We are running Linux, a mostly POSIX-compliant OS. POSIX standards it should be: Utility Argument Syntax.

• An option is a hyphen followed by a single alphanumeric character, like this: -o.
• An option may require an argument (which must appear immediately after the option); for example, -o argument or -oargument.
• Options that do not require arguments can be grouped after a hyphen, so, for example, -lst is equivalent to -t -l -s.
• Options can appear in any order; thus -lst is equivalent to -tls.
• Options can appear multiple times.
• Options precede other nonoption arguments: -lst nonoption.
• The -- argument terminates options.
• The - option is typically used to represent one of the standard input streams.

the accepted answer will break on white spaces if the directory names have them, and the preferred syntax is $() for bash/ksh. Use GNU find -exec option with +; eg

find .... -exec mycommand +; #this is same as passing to xargs

or use a while loop

find .... | while read -r D
do
    # use variable `D` or whatever variable name you defined instead here
done 

Try:

num3 = 100000000000LL;

And BTW, in C++ this is a compiler extension, the standard does not define long long, thats part of C99.

Given that the Apache Subversion server will be moved to this new DNS alias: sub.someaddress.com.tr:

• With Subversion 1.7 or higher, use svn relocate. Relocate is used when the SVN server's location changes. switch is only used if you want to change your local working copy to another branch or another path. If using TortoiseSVN, you may follow instructions from the TortoiseSVN Manual. If using the SVN command line interface, refer to this section of SVN's documentation. The command should look like this:

  svn relocate svn://sub.someaddress.com.tr/project

• Keep using /project given that the actual contents of your repository probably won't change.

Note: svn relocate is not available before version 1.7 (thanks to ColinM for the info). In older versions you would use:

    svn switch --relocate OLD NEW

<table cellspacing="0" cellpadding="0">

And in css:

table {border: none;}

EDIT: As iGEL noted, this solution is officially deprecated (still works though), so if you are starting from scratch, you should go with the jnpcl's border-collapse solution.

I actually quite dislike this change so far (don't work with tables that often). It makes some tasks bit more complicated. E.g. when you want to include two different borders in same place (visually), while one being TOP for one row, and second being BOTTOM for other row. They will collapse (= only one of them will be shown). Then you have to study how is border's "priority" calculated and what border styles are "stronger" (double vs. solid etc.).

I did like this:

<table cellspacing="0" cellpadding="0">
  <tr>
    <td class="first">first row</td>
  </tr>
  <tr>
    <td class="second">second row</td>
  </tr>
</table>

----------

.first {border-bottom:1px solid #EEE;}
.second {border-top:1px solid #CCC;}

Now, with border collapse, this won't work as there is always one border removed. I have to do it in some other way (there are more solutions ofc). One possibility is using CSS3 with box-shadow:

<table class="tab">
  <tr>
    <td class="first">first row</td>
  </tr>
  <tr>
    <td class="second">second row</td>
  </tr>
</table>???

<style>
.tab {border-collapse:collapse;}
.tab .first {border-bottom:1px solid #EEE;}
.tab .second {border-top:1px solid #CCC;box-shadow: inset 0 1px 0 #CCC;}?
</style>

You could also use something like "groove|ridge|inset|outset" border style with just a single border. But for me, this is not optimal, because I can't control both colors.

Maybe there is some simple and nice solution for collapsing borders, but I haven't seen it yet and I honestly haven't spent much time on it. Maybe someone here will be able to show me/us ;)

With Linear Layout

        android:layout_height="wrap_content"
        android:background="@drawable/select_car_book_tabbar"

            android:layout_gravity="center_vertical"
            android:src="@drawable/my_booking_icon" />
    </LinearLayout>

with FrameLayout

<FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

To run the batch file when the VM user logs in:

Drag the shortcut--the one that's currently on your desktop--(or the batch file itself) to Start - All Programs - Startup. Now when you login as that user, it will launch the batch file.

Another way to do the same thing is to save the shortcut or the batch file in %AppData%\Microsoft\Windows\Start Menu\Programs\Startup\.

As far as getting it to run full screen, it depends a bit what you mean. You can have it launch maximized by editing your batch file like this:

start "" /max "C:\Program Files\Oracle\VirtualBox\VirtualBox.exe" --comment "VM" --startvm "12dada4d-9cfd-4aa7-8353-20b4e455b3fa"

But if VirtualBox has a truly full-screen mode (where it hides even the taskbar), you'll have to look for a command-line parameter on VirtualBox.exe. I'm not familiar with that product.

HTML5 adds a maxlength attribute to the textarea element, like so:

<!DOCTYPE html>
<html>
    <body>
        <form action="processForm.php" action="post">
            <label for="story">Tell me your story:</label><br>
            <textarea id="story" maxlength="100"></textarea>
            <input type="submit" value="Submit">
        </form>
    </body>
</html>

This is currently supported in Chrome 13, FF 5, and Safari 5. Not surprisingly, this is not supported in IE 9. (Tested on Win 7)

First you need to write this codes

@Override
    protected void onCreate(Bundle savedInstanceState) {
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    }

Then add this line in manifest

 <activity android:name=".MainActivity"
            android:parentActivityName=".PreviousActivity"></activity>

I think it will work

You need to have better understanding of the python language and its standard library to translate the expression

cat "$filename": Reads the file cat "$filename" and dumps the content to stdout

|: pipe redirects the stdout from previous command and feeds it to the stdin of the next command

grep "something": Searches the regular expressionsomething plain text data file (if specified) or in the stdin and returns the matching lines.

cut -d'"' -f2: Splits the string with the specific delimiter and indexes/splices particular fields from the resultant list

Python Equivalent

cat "$filename"  | with open("$filename",'r') as fin:        | Read the file Sequentially
                 |     for line in fin:                      |   
-----------------------------------------------------------------------------------
grep 'something' | import re                                 | The python version returns
                 | line = re.findall(r'something', line)[0]  | a list of matches. We are only
                 |                                           | interested in the zero group
-----------------------------------------------------------------------------------
cut -d'"' -f2    | line = line.split('"')[1]                 | Splits the string and selects
                 |                                           | the second field (which is
                 |                                           | index 1 in python)

Combining

import re
with open("filename") as origin_file:
    for line in origin_file:
        line = re.findall(r'something', line)
        if line:
           line = line[0].split('"')[1]
        print line

If you have a worksheet with many rows that all contain the formula, by far the easiest method is to copy a row that is without data (but it does contain formulas), and then "insert copied cells" below/above the row where you want to add. The formulas remain. In a pinch, it is OK to use a row with data. Just clear it or overwrite it after pasting.

on socket.io 1.3.4 you have the following possibilities.

socket.handshake.address,

socket.conn.remoteAddress or

socket.request.client._peername.address

First, we're talking about packaging a Node.js app for workshops, demos, etc. where it can be handy to have an app "just running" without the need for the end user to care about installation and dependencies.

You can try the following setup:

1. Get your apps source code
2. npm install all dependencies (via package.json) to the local node_modules directory. It is important to perform this step on each platform you want to support separately, in case of binary dependencies.
3. Copy the Node.js binary – node.exe on Windows, (probably) /usr/local/bin/node on OS X/Linux to your project's root folder. On OS X/Linux you can find the location of the Node.js binary with which node.

For Windows:
Create a self extracting archive, 7zip_extra supports a way to execute a command right after extraction, see: http://www.msfn.org/board/topic/39048-how-to-make-a-7-zip-switchless-installer/.

For OS X/Linux:
You can use tools like makeself or unzipsfx (I don't know if this is compiled with CHEAP_SFX_AUTORUN defined by default).

These tools will extract the archive to a temporary directory, execute the given command (e.g. node app.js) and remove all files when finished.

These two settings worked for me to upload 1GB mp4 videos.

You did not mention what the command was that you were trying to run that produced the error message. However, the bottom line problem is that you are trying to run and/or install 32-bit (i686) packages on a 64-bit (x86_64) system which is not a good idea. For example, if you were trying to run the 32-bit version of Perl on a 64-bit system, the result would be something like

perl: /lib/ld-linux.so.2: bad ELF interpreter: No such file or directory

If you still want to use the rpm command to install the 32-bit versions of glibc and glibc-common on your system, then you need to know that you must install both of the packages at the same time and as a single command because they are dependencies of each other. The command to run in your case would be:

rpm -Uvh glibc-2.12-1.80.el6.i686.rpm glibc-common-2.12-1.80.el6.i686.rpm

This is what we ended up using:

n = 3
d = dict(raw_input().split() for _ in range(n))
print d

Input:

A1023 CRT
A1029 Regulator
A1030 Therm

Output:

{'A1023': 'CRT', 'A1029': 'Regulator', 'A1030': 'Therm'}

Depending on your browser support, you could use a css animation. Browser support is IE10 and up for CSS animation. This is nice so you don't have to add jquery UI dependency if its only a small easter egg. If it is integral to your site (aka needed for IE9 and below) go with the jquery UI solution.

.your-animation {
    background-color: #fff !important;
    -webkit-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
//You have to add the vendor prefix versions for it to work in Firefox, Safari, and Opera.
@-webkit-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
-moz-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-moz-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
-ms-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-ms-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
-o-animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@-o-keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}
animation: your-animation-name 1s ease 0s 1 alternate !important;
}
@keyframes your-animation-name {
    from { background-color: #5EB4FE;}
    to {background-color: #fff;}
}

Next create a jQuery click event that adds the your-animation class to the element you wish to animate, triggering the background fading from one color to another:

$(".some-button").click(function(e){
    $(".place-to-add-class").addClass("your-animation");
});

Both methods are used by many of the large players. It's a matter of preference. My preference is REST because it's simpler to use and understand.

Simple Object Access Protocol (SOAP):

• SOAP builds an XML protocol on top of HTTP or sometimes TCP/IP.
• SOAP describes functions, and types of data.
• SOAP is a successor of XML-RPC and is very similar, but describes a standard way to communicate.
• Several programming languages have native support for SOAP, you typically feed it a web service URL and you can call its web service functions without the need of specific code.
• Binary data that is sent must be encoded first into a format such as base64 encoded.
• Has several protocols and technologies relating to it: WSDL, XSDs, SOAP, WS-Addressing

Representational state transfer (REST):

• REST need not be over HTTP but most of my points below will have an HTTP bias.
• REST is very lightweight, it says wait a minute, we don't need all of this complexity that SOAP created.
• Typically uses normal HTTP methods instead of a big XML format describing everything. For example to obtain a resource you use HTTP GET, to put a resource on the server you use HTTP PUT. To delete a resource on the server you use HTTP DELETE.
• REST is a very simple in that it uses HTTP GET, POST and PUT methods to update resources on the server.
• REST typically is best used with Resource Oriented Architecture (ROA). In this mode of thinking everything is a resource, and you would operate on these resources.
• As long as your programming language has an HTTP library, and most do, you can consume a REST HTTP protocol very easily.
• Binary data or binary resources can simply be delivered upon their request.

There are endless debates on REST vs SOAP on google.

My favorite is this one. Update 27 Nov 2013: Paul Prescod's site appears to have gone offline and this article is no longer available, copies though can be found on the Wayback Machine or as a PDF at CiteSeerX.

Here is how I automatically start the MySQL service whenever the docker container runs.

On my case, I need to run not just MySQL but also PHP, Nginx and Memcached

I have the following lines in Dockerfile

RUN echo "daemon off;" >> /etc/nginx/nginx.conf
EXPOSE 80
EXPOSE 3306
CMD service mysql start && service php-fpm start && nginx -g 'daemon off;' && service memcached start && bash

Adding && bash would keep Nginx, MySQL, PHP and Memcached running within the container.

Once you're in the directory, just run it as ./myScript.sh

When leaving the current page, the CollectionView associated with the ItemsSource property of the ComboBox is purged. And because the ComboBox IsSyncronizedWithCurrent property is true by default, the SelectedItem and SelectedValue properties are reset.
This seems to be an internal data type issue in the binding. As others suggested above, if you use SelectedValue instead by binding to an int property on the viewmodel, it will work. A shortcut for you would be to override the Equals operator on MyObject so that when comparing two MyObjects, the actual Id properties are compared.

Another hint: If you do restructure your viewmodels and use SelectedValue, use it only when SelectedValuePath=Id where Id is int. If using a string key, bind to the Text property of the ComboBox instead of SelectedValue.

Striking a similar issue using CakePHP to output a JavaScript script-block using PHP's native json_encode. $contractorCompanies contains values that have single quotation marks and as explained above and expected json_encode($contractorCompanies) doesn't escape them because its valid JSON.

<?php $this->Html->scriptBlock("var contractorCompanies = jQuery.parseJSON( '".(json_encode($contractorCompanies)."' );"); ?>

By adding addslashes() around the JSON encoded string you then escape the quotation marks allowing Cake / PHP to echo the correct javascript to the browser. JS errors disappear.

<?php $this->Html->scriptBlock("var contractorCompanies = jQuery.parseJSON( '".addslashes(json_encode($contractorCompanies))."' );"); ?>

Math.round is one answer,

public class Util {
 public static Double formatDouble(Double valueToFormat) {
    long rounded = Math.round(valueToFormat*100);
    return rounded/100.0;
 }
}

Test in Spock,Groovy

void "test double format"(){
    given:
         Double performance = 0.6666666666666666
    when:
        Double formattedPerformance = Util.formatDouble(performance)
        println "######################## formatted ######################### => ${formattedPerformance}"
    then:
        0.67 == formattedPerformance

}

This UDF will work for all types of strings:

CREATE FUNCTION udf_getNumbersFromString (@string varchar(max))
RETURNS varchar(max)
AS
BEGIN
    WHILE  @String like '%[^0-9]%'
    SET    @String = REPLACE(@String, SUBSTRING(@String, PATINDEX('%[^0-9]%', @String), 1), '')
    RETURN @String
END

Please try this it's working for me

onClick="window.open('http://www.facebook.com/','facebook')"

<button type="button" class="btn btn-default btn-social" onClick="window.open('http://www.facebook.com/','facebook')">
          <i class="fa fa-facebook" aria-hidden="true"></i>
</button>

Or take the .not() method

https://api.jquery.com/not/

$(".thisClass").not("#thisId").doAction();

Besides using the INFORMATION_SCHEMA table, to use SHOW TABLES to insert into a table you would use the following

<?php
 $sql = "SHOW TABLES FROM $dbname";
 $result = mysql_query($sql);
 $arrayCount = 0
 while ($row = mysql_fetch_row($result)) {
  $tableNames[$arrayCount] = $row[0];
  $arrayCount++; //only do this to make sure it starts at index 0
 }
 foreach ($tableNames as &$name {
  $query = "INSERT INTO metadata (table_name) VALUES ('".$name."')";
  mysql_query($query);
 }
?>

May be you are using this checking :

if (Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT) {
}

To resolve this you need to import android.provider.DocumentsContract class.

To resolve this issue you'll need to set the build SDK version to 19 (4.4) or higher to have API level 19 symbols available while compiling.

First, use the SDK Manager to download API 19 if you don't have it yet. Then, configure your project to use API 19:

• In Android Studio: File -> Project Structure -> General Settings -> Project SDK.
• In Eclipse ADT: Project Properties -> Android -> Project Build Target

I found this answer from here

Thanks .

Some CSS :

table td, table td * {
    vertical-align: top;
}

The problem is actually that you need to double-escape backslashes in the replacement string. You see, "\\/" (as I'm sure you know) means the replacement string is \/, and (as you probably don't know) the replacement string \/ actually just inserts /, because Java is weird, and gives \ a special meaning in the replacement string. (It's supposedly so that \$ will be a literal dollar sign, but I think the real reason is that they wanted to mess with people. Other languages don't do it this way.) So you have to write either:

"Hello/You/There".replaceAll("/", "\\\\/");

or:

"Hello/You/There".replaceAll("/", Matcher.quoteReplacement("\\/"));

(Using java.util.regex.Matcher.quoteReplacement(String).)

You should use a mediator for this. Mediator is a common design pattern also known as Messenger in some of its implementations. It's a paradigm of type Register/Notify and enables your ViewModel and Views to communicate through a low-coupled messaging mecanism.

You should check out the google WPF Disciples group, and just search for Mediator. You will be much happy with the answers...

You can however start with this:

I just now wrote a log handler of my own that just feeds everything to the parent process via a pipe. I've only been testing it for ten minutes but it seems to work pretty well.

(Note: This is hardcoded to RotatingFileHandler, which is my own use case.)

Update: @javier now maintains this approach as a package available on Pypi - see multiprocessing-logging on Pypi, github at https://github.com/jruere/multiprocessing-logging

Update: Implementation!

This now uses a queue for correct handling of concurrency, and also recovers from errors correctly. I've now been using this in production for several months, and the current version below works without issue.

from logging.handlers import RotatingFileHandler
import multiprocessing, threading, logging, sys, traceback

class MultiProcessingLog(logging.Handler):
    def __init__(self, name, mode, maxsize, rotate):
        logging.Handler.__init__(self)

        self._handler = RotatingFileHandler(name, mode, maxsize, rotate)
        self.queue = multiprocessing.Queue(-1)

        t = threading.Thread(target=self.receive)
        t.daemon = True
        t.start()

    def setFormatter(self, fmt):
        logging.Handler.setFormatter(self, fmt)
        self._handler.setFormatter(fmt)

    def receive(self):
        while True:
            try:
                record = self.queue.get()
                self._handler.emit(record)
            except (KeyboardInterrupt, SystemExit):
                raise
            except EOFError:
                break
            except:
                traceback.print_exc(file=sys.stderr)

    def send(self, s):
        self.queue.put_nowait(s)

    def _format_record(self, record):
        # ensure that exc_info and args
        # have been stringified.  Removes any chance of
        # unpickleable things inside and possibly reduces
        # message size sent over the pipe
        if record.args:
            record.msg = record.msg % record.args
            record.args = None
        if record.exc_info:
            dummy = self.format(record)
            record.exc_info = None

        return record

    def emit(self, record):
        try:
            s = self._format_record(record)
            self.send(s)
        except (KeyboardInterrupt, SystemExit):
            raise
        except:
            self.handleError(record)

    def close(self):
        self._handler.close()
        logging.Handler.close(self)

you can give it a max-height and max-width in your .css

.fontpixel{max-width:200px; max-height:200px;}

in addition to your height and width properties

You can use the NotMapped attribute data annotation to instruct Code-First to exclude a particular property

public class Customer
{
    public int CustomerID { set; get; }
    public string FirstName { set; get; } 
    public string LastName{ set; get; } 
    [NotMapped]
    public int Age { set; get; }
}

[NotMapped] attribute is included in the System.ComponentModel.DataAnnotations namespace.

You can alternatively do this with Fluent API overriding OnModelCreating function in your DBContext class:

protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
   modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
   base.OnModelCreating(modelBuilder);
}

http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx

The version I checked is EF 4.3, which is the latest stable version available when you use NuGet.

Edit : SEP 2017

Asp.NET Core(2.0)

Data annotation

If you are using asp.net core (2.0 at the time of this writing), The [NotMapped] attribute can be used on the property level.

public class Customer
{
    public int Id { set; get; }
    public string FirstName { set; get; } 
    public string LastName { set; get; } 
    [NotMapped]
    public int FullName { set; get; }
}

Fluent API

public class SchoolContext : DbContext
{
    public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
    {
    }
    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
        base.OnModelCreating(modelBuilder);
    }
    public DbSet<Customer> Customers { get; set; }
}

For what it is worth, most scripting languages (like Perl) and non-static compile-time languages (like Pick) support automatic run-time dynamic String to (relatively arbitrary) object conversions. This CAN be accomplished in Java as well without losing type-safety and the good stuff statically-typed languages provide WITHOUT the nasty side-effects of some of the other languages that do evil things with dynamic casting. A Perl example that does some questionable math:

print ++($foo = '99');  # prints '100'
print ++($foo = 'a0');  # prints 'a1'

In Java, this is better accomplished (IMHO) by using a method I call "cross-casting". With cross-casting, reflection is used in a lazy-loaded cache of constructors and methods that are dynamically discovered via the following static method:

Object fromString (String value, Class targetClass)

Unfortunately, no built-in Java methods such as Class.cast() will do this for String to BigDecimal or String to Integer or any other conversion where there is no supporting class hierarchy. For my part, the point is to provide a fully dynamic way to achieve this - for which I don't think the prior reference is the right approach - having to code every conversion. Simply put, the implementation is just to cast-from-string if it is legal/possible.

So the solution is simple reflection looking for public Members of either:

STRING_CLASS_ARRAY = (new Class[] {String.class});

a) Member member = targetClass.getMethod(method.getName(),STRING_CLASS_ARRAY); b) Member member = targetClass.getConstructor(STRING_CLASS_ARRAY);

You will find that all of the primitives (Integer, Long, etc) and all of the basics (BigInteger, BigDecimal, etc) and even java.regex.Pattern are all covered via this approach. I have used this with significant success on production projects where there are a huge amount of arbitrary String value inputs where some more strict checking was needed. In this approach, if there is no method or when the method is invoked an exception is thrown (because it is an illegal value such as a non-numeric input to a BigDecimal or illegal RegEx for a Pattern), that provides the checking specific to the target class inherent logic.

There are some downsides to this:

1) You need to understand reflection well (this is a little complicated and not for novices). 2) Some of the Java classes and indeed 3rd-party libraries are (surprise) not coded properly. That is, there are methods that take a single string argument as input and return an instance of the target class but it isn't what you think... Consider the Integer class:

static Integer getInteger(String nm)
      Determines the integer value of the system property with the specified name.

The above method really has nothing to do with Integers as objects wrapping primitives ints. Reflection will find this as a possible candidate for creating an Integer from a String incorrectly versus the decode, valueof and constructor Members - which are all suitable for most arbitrary String conversions where you really don't have control over your input data but just want to know if it is possible an Integer.

To remedy the above, looking for methods that throw Exceptions is a good start because invalid input values that create instances of such objects should throw an Exception. Unfortunately, implementations vary as to whether the Exceptions are declared as checked or not. Integer.valueOf(String) throws a checked NumberFormatException for example, but Pattern.compile() exceptions are not found during reflection lookups. Again, not a failing of this dynamic "cross-casting" approach I think so much as a very non-standard implementation for exception declarations in object creation methods.

If anyone would like more details on how the above was implemented, let me know but I think this solution is much more flexible/extensible and with less code without losing the good parts of type-safety. Of course it is always best to "know thy data" but as many of us find, we are sometimes only recipients of unmanaged content and have to do the best we can to use it properly.

Cheers.

In pure Javascript, I cannot think of anything more idiomatic than your first code snippet.

If, however, using the jQuery library is not out of the question, then $.extend() should meet your requirements because, as the documentation says:

Undefined properties are not copied.

Therefore, you can write:

var a = $.extend({}, {
    b: conditionB ? 5 : undefined,
    c: conditionC ? 5 : undefined,
    // and so on...
});

And obtain the results you expect (if conditionB is false, then b will not exist in a).

To find all configurations, you just write this command:

git config --list

In my local i run this command .

It's better to move all logic of working with database to repositores.

So in controller you write

/* you can also inject "FooRepository $repository" using autowire */
$repository = $this->getDoctrine()->getRepository(Foo::class);
$count = $repository->count();

And in Repository/FooRepository.php

public function count()
{
    $qb = $repository->createQueryBuilder('t');
    return $qb
        ->select('count(t.id)')
        ->getQuery()
        ->getSingleScalarResult();
}

It's better to move $qb = ... to separate row in case you want to make complex expressions like

public function count()
{
    $qb = $repository->createQueryBuilder('t');
    return $qb
        ->select('count(t.id)')
        ->where($qb->expr()->isNotNull('t.fieldName'))
        ->andWhere($qb->expr()->orX(
            $qb->expr()->in('t.fieldName2', 0),
            $qb->expr()->isNull('t.fieldName2')
        ))
        ->getQuery()
        ->getSingleScalarResult();
}

Also think about caching your query result - http://symfony.com/doc/current/reference/configuration/doctrine.html#caching-drivers

public function count()
{
    $qb = $repository->createQueryBuilder('t');
    return $qb
        ->select('count(t.id)')
        ->getQuery()
        ->useQueryCache(true)
        ->useResultCache(true, 3600)
        ->getSingleScalarResult();
}

In some simple cases using EXTRA_LAZY entity relations is good
http://doctrine-orm.readthedocs.org/projects/doctrine-orm/en/latest/tutorials/extra-lazy-associations.html

Please put this code in head section

<link href='http://fonts.googleapis.com/css?family=Lato:400,700' rel='stylesheet' type='text/css'>

and use font-family: 'Lato', sans-serif; in your css. For example:

h1 {
    font-family: 'Lato', sans-serif;
    font-weight: 400;
}

Or you can use manually also

Generate .ttf font from fontSquiral

and can try this option

    @font-face {
        font-family: "Lato";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}

Called like this

body {
  font-family: 'Lato', sans-serif;
}

Here is how I was able to use Boost:

1. Download and extract the zip version of Boost libraries.
2. Run bootstrap.bat file and then run bjam.exe.
3. Wait for roughly 30 minutes or so.
4. Create a new project in Visual Studio.
5. Go to project-->properties-->Linker-->General-->Additional Library Directories and add boost/stage/lib directory to it.
6. Go to project-->properties-->C/C++-->General-->Additional Include Directories and add boost directory to it.

You will be able to build your project without any errors !

JSfiddle

function deleteEmpty(obj){
        for(var k in obj)
         if(k == "children"){
             if(obj[k]){
                     deleteEmpty(obj[k]);
             }else{
                   delete obj.children;
              } 
         }
    }

 deleteEmpty(a.children[i])

For my Azpen A727, the Windows driver installed correctly, so only step 3 of Mohammad's answer was necessary.

1) Method1 saving list1 is dictionary and then iterating each elem in list2

def findarrayhash(a,b):
    h1={k:1 for k in a}
    for val in b:
        if val in h1:
            print("common found",val)
            del h1[val]
        else:
            print("different found",val)
    for key in h1.iterkeys():
        print ("different found",key)

Finding Common and Different elements:

2) Method2 using set

def findarrayset(a,b):
    common = set(a)&set(b)
    diff=set(a)^set(b)
    print list(common)
    print list(diff) 

I'll post this here in case it's useful to anyone…

On iOS Safari, calls to navigator.geolocation.getCurrentPosition would timeout if I had an active navigator.geolocation.watchPosition function running.

Starting and stopping the watchPosition properly using clearWatch() as described here, worked: https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/watchPosition

If you need to do a file upload, you'll need to use MediaType.MULTIPART_FORM_DATA_TYPE. Looks like MultivaluedMap cannot be used with that so here's a solution with FormDataMultiPart.

InputStream stream = getClass().getClassLoader().getResourceAsStream(fileNameToUpload);

FormDataMultiPart part = new FormDataMultiPart();
part.field("String_key", "String_value");
part.field("fileToUpload", stream, MediaType.TEXT_PLAIN_TYPE);
String response = WebResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(String.class, part);

"Best" depends on the scenario. There are times when you only care about the smallest possible single bundle, but in large apps you may have to consider lazy loading. At some point it becomes impractical to serve the entire app as a single bundle.

In the latter case Webpack is generally the best way since it supports code splitting.

For a single bundle I would consider Rollup, or the Closure compiler if you are feeling brave :-)

I have created samples of all Angular bundlers I've ever used here: http://www.syntaxsuccess.com/viewarticle/angular-production-builds

The code can be found here: https://github.com/thelgevold/angular-2-samples

Angular version: 4.1.x

$('#cloneDiv').click(function(){_x000D_
_x000D_
_x000D_
  // get the last DIV which ID starts with ^= "klon"_x000D_
  var $div = $('div[id^="klon"]:last');_x000D_
_x000D_
  // Read the Number from that DIV's ID (i.e: 3 from "klon3")_x000D_
  // And increment that number by 1_x000D_
  var num = parseInt( $div.prop("id").match(/\d+/g), 10 ) +1;_x000D_
_x000D_
  // Clone it and assign the new ID (i.e: from num 4 to ID "klon4")_x000D_
  var $klon = $div.clone().prop('id', 'klon'+num );_x000D_
_x000D_
  // Finally insert $klon wherever you want_x000D_
  $div.after( $klon.text('klon'+num) );_x000D_
_x000D_
});

<script src="https://code.jquery.com/jquery-3.1.0.js"></script>_x000D_
_x000D_
<button id="cloneDiv">CLICK TO CLONE</button> _x000D_
_x000D_
<div id="klon1">klon1</div>_x000D_
<div id="klon2">klon2</div>

Scrambled elements, retrieve highest ID

Say you have many elements with IDs like klon--5 but scrambled (not in order). Here we cannot go for :last or :first, therefore we need a mechanism to retrieve the highest ID:

const $all = $('[id^="klon--"]');_x000D_
const maxID = Math.max.apply(Math, $all.map((i, el) => +el.id.match(/\d+$/g)[0]).get());_x000D_
const nextId = maxID + 1;_x000D_
_x000D_
console.log(`New ID is: ${nextId}`);

<div id="klon--12">12</div>_x000D_
<div id="klon--34">34</div>_x000D_
<div id="klon--8">8</div>_x000D_
_x000D_
<script src="https://code.jquery.com/jquery-3.1.0.js"></script>

One option would be to use a helper extension method like follows:

public static class MyExtensions
{
    public static System.Type Type<T>(this T v)=>typeof(T);
}

var i=0;
console.WriteLine(i.Type().FullName);

Sorry, didn't quite get your question. So something like this?

str.ToCharArray().Any(char.IsDigit);

Or does the value have to be an integer completely, without any additional strings?

if(str.ToCharArray().All(char.IsDigit(c));

I was able to resolve this by following the steps posted here: xampp phpmyadmin, Incorrect format parameter

Because I'm not using XAMPP, I also needed to update my php.ini.default to php.ini which finally did the trick.

It looks like the class.phpmailer.php file is corrupt. I would download the latest version and try again.

I've always used phpMailer's SMTP feature:

$mail->IsSMTP();
$mail->Host = "localhost";

And if you need debug info:

$mail->SMTPDebug  = 2; // enables SMTP debug information (for testing)
                       // 1 = errors and messages
                       // 2 = messages only

This tutorial:

http://techdroid.kbeanie.com/2010/02/sign-your-android-applications-for.html

was very helpful for me the first time I had to create a keystore. It is simple but the instructions on developer.android.com are a little too brief.

The part I was unsure about was where to save and what name to give the keystore file.

I seems it doesn't matter where you put it just be sure to keep it safe and keep a number of backups. I just put it in my app directory

Name the file "something.keystore" where something can be whatever you want. I used app_name.keystore, where app_name was the name of my app.

The next part was what to name the alias. Again it doesn't seem to matter so again I just used the app_name again. Keep the passwords the same as you used before. Fill out the rest of the fields and you are done.

Since you tagged it Rails, you can use truncate:

http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-truncate

Example:

 truncate(@text, :length => 17)

Excerpt is nice to know too, it lets you display an excerpt of a text Like so:

 excerpt('This is an example', 'an', :radius => 5)
 # => ...s is an exam...

http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-excerpt

For example, I will create a table called users as below and give a column named date a default value NOW()

create table users_parent (
    user_id     varchar(50),
    full_name   varchar(240),
    login_id_1  varchar(50),
    date        timestamp NOT NULL DEFAULT NOW()
);

Thanks

I am just sharing my experience here, I used angular.copy() for comparing two objects properties. I was working on a number of inputs without form element, I was wondering how to compare two objects properties and based on result I have to enable and disable the save button. So I used as below.

I assigned an original server object user values to my dummy object to say userCopy and used watch to check changes to the user object.

My server API which gets me data from the server:

var req = {
    method: 'GET',
    url: 'user/profile/' + id,
    headers: { 'Content-Type': 'application/x-www-form-urlencoded' }
}
$http(req).success(function(data) {
    $scope.user = data;
    $scope.userCopy = angular.copy($scope.user);
    $scope.btnSts=true;
}).error(function(data) {
    $ionicLoading.hide();
});

//initially my save button is disabled because objects are same, once something 
//changes I am activating save button

$scope.btnSts = true;
$scope.$watch('user', function(newVal, oldVal) {
    console.log($scope.userCopy.name);

    if ($scope.userCopy.name !== $scope.user.name || $scope.userCopy.email !== $scope.user.email) {
        console.log('Changed');
        $scope.btnSts = false;
    } else {
        console.log('Unchanged');
        $scope.btnSts = true;
    }    
}, true);

I am not sure but comparing two objects was really headache for me always but with angular.copy() it went smoothly.

Don't echo out HTML.

If you want to use

<?php echo "<h1>  $title; </h1>"; ?>

you should be doing this:

<h1><?= $title;?></h1>

There are security flaws to using preg_replace(), if you get the payload from user input [or other untrusted sources]. PHP executes the regular expression with eval(). If the incoming string isn't properly sanitized, your application risks being subjected to code injection.

In my own application, instead of bothering sanitizing the input (and as I only deal with short strings), I instead made a slightly more processor intensive function, though which is secure, since it doesn't eval() anything.

function secureRip(string $str): string { /* Rips all whitespace securely. */
  $arr = str_split($str, 1);
  $retStr = '';
  foreach ($arr as $char) {
    $retStr .= trim($char);
  }
  return $retStr;
}

To achieve a generic solution, why not do this:

$(':reset').live('click', function(){
    var $r = $(this);
    setTimeout(function(){ 
        $r.closest('form').find('.select2-offscreen').trigger('change'); 
    }, 10);
});

This way: You'll not have to make a new logic for each select2 on your application.

And, you don't have to know the default value (which, by the way, does not have to be "" or even the first option)

Finally, setting the value to :selected would not always achieve a true reset, since the current selected might well have been set programmatically on the client, whereas the default action of the form select is to return input element values to the server-sent ones.

EDIT: Alternatively, considering the deprecated status of live, we could replace the first line with this:

$('form:has(:reset)').on('click', ':reset', function(){

or better still:

$('form:has(:reset)').on('reset', function(){

PS: I personally feel that resetting on reset, as well as triggering blur and focus events attached to the original select, are some of the most conspicuous "missing" features in select2!

Use the android.webkit.URLUtil on android:

According to the Oracle PLSQL language definition, a character literal can contain "any printable character in the character set". https://docs.oracle.com/cd/A97630_01/appdev.920/a96624/02_funds.htm#2876

@Robert Love's answer exhibits a best practice for readable code, but you can also just type in the linefeed character into the code. Here is an example from a Linux terminal using sqlplus:

SQL> set serveroutput on
SQL> begin   
  2  dbms_output.put_line( 'hello' || chr(10) || 'world' );
  3  end;
  4  /
hello
world

PL/SQL procedure successfully completed.

SQL> begin
  2  dbms_output.put_line( 'hello
  3  world' );
  4  end;
  5  /
hello
world

PL/SQL procedure successfully completed.

Instead of the CHR( NN ) function you can also use Unicode literal escape sequences like u'\0085' which I prefer because, well you know we are not living in 1970 anymore. See the equivalent example below:

SQL> begin
  2  dbms_output.put_line( 'hello' || u'\000A' || 'world' );
  3  end;
  4  /
hello
world

PL/SQL procedure successfully completed.

For fair coverage I guess it is worth noting that different operating systems use different characters/character sequences for end of line handling. You've got to have a think about the context in which your program output is going to be viewed or printed, in order to determine whether you are using the right technique.

• Microsoft Windows: CR/LF or u'\000D\000A'
• Unix (including Apple MacOS): LF or u'\000A'
• IBM OS390: NEL or u'\0085'
• HTML: '<BR>'
• XHTML: '<br />'
• etc. etc.

Solution for iOS 11

Short App Store URLs do not correctly open the "write a review" interface in the new iOS 11 App Store. For example, this does not work:

https://itunes.apple.com/app/id333903271?mt=8&action=write-review

The workaround is to include a two-letter country code and app name in the URL, such as this:

https://itunes.apple.com/us/app/twitter/id333903271?mt=8&action=write-review

or

itms-apps://itunes.apple.com/us/app/twitter/id333903271?mt=8&action=write-review

You can get the full URL of your app from here: https://linkmaker.itunes.apple.com/

This successfully opens the "write a review" interface in the iOS 11 App Store.

Edit: As @Theo mentions below, the country code does not need to be localized and the app name in the URL does not need to be updated if the app name changes.

Hopefully Apple will fix this soon for the shorter URL. See rdar://34498138

After having spent over an hour going in rounds swearing at Samsung (mostly), Google, and who not, here are my findings, that finally helped me get the device recognized:

• On Device:
  • Set developer mode
  • Allow USB debugging
  • Default USB configuration > Select USB tethering
  • Connect device to PC USB
• On PC:
  • Elevated cmd/ps prompt (maybe not mandatory, but that was my drill)
  • adb kill-server (precede with .\ in ps)
  • adb start-server (while device connected) > watch for prompt on device
• On device:
  • Always allow connections from this computer > Yes
• On PC:
  • adb devices gets the following output:

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

This answer is for Ubuntu users looking for a solution without writing SQL queries.

The following is the initial screen you'll get after opening it

In the top right, where it says Administration, click in the arrow to the right

This will show Schema (instead of Administration) and it's possible to see a sys database.

Right click in the grey area after functions and click Create Schema...

This will open the following where I'm creating a table named StackOverflow_db

Clicking in the bottom right button that says "Apply",

And in this new view click in "Apply" too. In the end you'll get a database called StackOverflow_db

The problem with all presented answers it complete lack of taking triggers (and probably other side effects) into account. Solution like

INSERT OR IGNORE ...
UPDATE ...

leads to both triggers executed (for insert and then for update) when row does not exist.

Proper solution is

UPDATE OR IGNORE ...
INSERT OR IGNORE ...

in that case only one statement is executed (when row exists or not).

"tail" is command to display the last part of a file, using proper available switches helps us to get more specific output. the most used switch for me is -n and -f

SYNOPSIS

tail [-F | -f | -r] [-q] [-b number | -c number | -n number] [file ...]

Here

-n number : The location is number lines.

-f : The -f option causes tail to not stop when end of file is reached, but rather to wait for additional data to be appended to the input. The -f option is ignored if the standard input is a pipe, but not if it is a FIFO.

Retrieve last 100 lines logs

To get last static 100 lines  
     tail -n 100 <file path>

To get real time last 100 lines
     tail -f -n 100 <file path>

Some threads do background tasks, like sending keepalive packets, or performing periodic garbage collection, or whatever. These are only useful when the main program is running, and it's okay to kill them off once the other, non-daemon, threads have exited.

Without daemon threads, you'd have to keep track of them, and tell them to exit, before your program can completely quit. By setting them as daemon threads, you can let them run and forget about them, and when your program quits, any daemon threads are killed automatically.

I'd recommend you to use Bytescout Spreadsheet.

I tried it with Monodevelop in Unity3D and it is pretty straight forward. Check this sample code to see how the library works:

I believe that @Matthew Crumley is right. They are functionally, if not structurally, equivalent. If you use Firebug to look at the objects that are created using new, you can see that they are the same. However, my preference would be the following. I'm guessing that it just seems more like what I'm used to in C#/Java. That is, define the class, define the fields, constructor, and methods.

var A = function() {};
A.prototype = {
    _instance_var: 0,

    initialize: function(v) { this._instance_var = v; },

    x: function() {  alert(this._instance_var); }
};

EDIT Didn't mean to imply that the scope of the variable was private, I was just trying to illustrate how I define my classes in javascript. Variable name has been changed to reflect this.

First you have to change the rendering property of the image to "Template Image" in the .xcassets folder. You can then just change the tint color property of the instance of your UIImageView like so:

imageView.tintColor = UIColor.whiteColor()

first you don't need to add the classRules explicitly since required is automatically detected by the jquery.validate plugin. so you can use this code :

1. on form submit , you prevent the default behavior
2. if the form is Invalid stop the execution.
3. else if valid send the ajax request.

$('#form').submit(function (e) {
  e.preventDefault();
  var $form = $(this);

  // check if the input is valid using a 'valid' property
  if (!$form.valid) return false;

  $.ajax({
    type: 'POST',
    url: 'add.php',
    data: $('#form').serialize(),
    success: function (response) {
      $('#answers').html(response);
    },
  });
});

It turns out that it was shrinking and growing correctly, providing the desired behaviour all along; except that in all current browsers flexbox wasn't accounting for the vertical scrollbar! Which is why the content appears to be getting cut off.

You can see here, which is the original code I was using before I added the fixed widths, that it looks like the column isn't growing to accomodate the text:

http://jsfiddle.net/2w157dyL/1/

However if you make the content in that column wider, you'll see that it always cuts it off by the same amount, which is the width of the scrollbar.

So the fix is very, very simple - add enough right padding to account for the scrollbar:

http://jsfiddle.net/2w157dyL/2/

  main > section {_x000D_
    overflow-y: auto;_x000D_
    padding-right: 2em;_x000D_
  }

It was when I was trying some things suggested by Michael_B (specifically adding a padding buffer) that I discovered this, thanks so much!

Edit: I see that he also posted a fiddle which does the same thing - again, thanks so much for all your help

As to the concrete problem with that SQLException, you need to replace

ResultSet rs = stmt.executeQuery(sql);

by

ResultSet rs = stmt.executeQuery();

because you're using the PreparedStatement subclass instead of Statement. When using PreparedStatement, you've already passed in the SQL string to Connection#prepareStatement(). You just have to set the parameters on it and then call executeQuery() method directly without re-passing the SQL string.

See also:

• JDBC tutorial - Using Prepared Statements

As to the concrete question about rs.next(), it shifts the cursor to the next row of the result set from the database and returns true if there is any row, otherwise false. In combination with the if statement (instead of the while) this means that the programmer is expecting or interested in only one row, the first row.

See also:

• Javadoc on ResultSet#next() method
• Problem with SQL, ResultSet in java

Yes: you can sort using a custom comparison function:

std::sort(info.begin(), info.end(), my_custom_comparison);

my_custom_comparison needs to be a function or a class with an operator() overload (a functor) that takes two data objects and returns a bool indicating whether the first is ordered prior to the second (i.e., first < second). Alternatively, you can overload operator< for your class type data; operator< is the default ordering used by std::sort.

Either way, the comparison function must yield a strict weak ordering of the elements.

I realise I'm a litle late to the game, but just spent over a day on trying to change the timeout of a webservice. It seemed to have a default timeout of 30 seconds. I after changing evry other timeout value I could find, including:

• DB connection string Connect Timeout
• httpRuntime executionTimeout
• basicHttpBinding binding closeTimeout
• basicHttpBinding binding sendTimeout
• basicHttpBinding binding receiveTimeout
• basicHttpBinding binding openTimeout

Finaley I found that it was the SqlCommand timeout that was defaulting to 30 seconds.

I decided to just duplicate the timeout of the connection string to the command. The connection string is configured in the web.config.

Some code:

namespace ROS.WebService.Common
{
  using System;
  using System.Configuration;
  using System.Data;
  using System.Data.SqlClient;

  public static class DataAccess
  {
    public static string ConnectionString { get; private set; }

    static DataAccess()
    {
      ConnectionString = ConfigurationManager.ConnectionStrings["ROSdb"].ConnectionString;
    }

    public static int ExecuteNonQuery(string cmdText, CommandType cmdType, params SqlParameter[] sqlParams)
    {
      using (SqlConnection conn = new SqlConnection(DataAccess.ConnectionString))
      {
        using (SqlCommand cmd = new SqlCommand(cmdText, conn) { CommandType = cmdType, CommandTimeout = conn.ConnectionTimeout })
        {
          foreach (var p in sqlParams) cmd.Parameters.Add(p);
          cmd.Connection.Open();
          return cmd.ExecuteNonQuery();
        }
      }
    }
  }
}

Change introduced to "duplicate" the timeout value from the connection string:CommandTimeout = conn.ConnectionTimeout

Simplify. Cherry-pick the commits. Don't cherry-pick the merge.

Here's a rewrite of the accepted answer that ideally clarifies the advantages/risks of possible approaches:

You're trying to cherry pick fd9f578, which was a merge with two parents.

Instead of cherry-picking a merge, the simplest thing is to cherry pick the commit(s) you actually want from each branch in the merge.

Since you've already merged, it's likely all your desired commits are in your list. Cherry-pick them directly and you don't need to mess with the merge commit.

explanation

The way a cherry-pick works is by taking the diff that a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying the changeset to your current branch.

If a commit has two or more parents, as is the case with a merge, that commit also represents two or more diffs. The error occurs because of the uncertainty over which diff should apply.

alternatives

If you determine you need to include the merge vs cherry-picking the related commits, you have two options:

1. (More complicated and obscure; also discards history) you can indicate which parent should apply.

   • Use the -m option to do so. For example, git cherry-pick -m 1 fd9f578 will use the first parent listed in the merge as the base.

   • Also consider that when you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m into that one commit. You lose all their history, and glom together all their diffs. Your call.

2. (Simpler and more familiar; preserves history) you can use git merge instead of git cherry-pick.

   • As is usual with git merge, it will attempt to apply all commits that exist on the branch you are merging, and list them individually in your git log.

The warning indicates that you're not returning something at the end of your map arrow function in every case.

A better approach to what you're trying to accomplish is first using a .filter and then a .map, like this:

this.props.comments
  .filter(commentReply => commentReply.replyTo === comment.id)
  .map((commentReply, idx) => <CommentItem key={idx} className="SubComment"/>);

There are three ways to do this, depending on your needs. You could use the old-school C way and call fopen/fread/fclose, or you could use the C++ fstream facilities (ifstream/ofstream), or if you're using MFC, use the CFile class, which provides functions to accomplish actual file operations.

All of these are suitable for both text and binary, though none have a specific readline functionality. What you'd most likely do instead in that case is use the fstream classes (fstream.h) and use the stream operators (<< and >>) or the read function to read/write blocks of text:

int nsize = 10;
char *somedata;
ifstream myfile;
myfile.open("<path to file>");
myfile.read(somedata,nsize);
myfile.close();

Note that, if you're using Visual Studio 2005 or higher, traditional fstream may not be available (there's a new Microsoft implementation, which is slightly different, but accomplishes the same thing).

if you have two divs, you can use this to align the divs next to each other in the same row:

#keyword {_x000D_
    float:left;_x000D_
    margin-left:250px;_x000D_
    position:absolute;_x000D_
}_x000D_
_x000D_
#bar {_x000D_
    text-align:center;_x000D_
}

<div id="keyword">_x000D_
Keywords:_x000D_
</div>_x000D_
<div id="bar">_x000D_
    <input type = textbox   name ="keywords" value="" onSubmit="search()" maxlength=40>_x000D_
    <input type = button   name="go" Value="Go ahead and find" onClick="search()">_x000D_
</div>

Strange. Inside OnCreate method, I'm using

webView.getSettings().setBuiltInZoomControls(true);

And it's working fine here. Anything particular in your webview ?

void foo(void);

That is the correct way to say "no parameters" in C, and it also works in C++.

But:

void foo();

Means different things in C and C++! In C it means "could take any number of parameters of unknown types", and in C++ it means the same as foo(void).

Variable argument list functions are inherently un-typesafe and should be avoided where possible.

If this were PHP I'd build an array with the keys and take array_keys at the end, but JS has no such luxury. Instead, try this:

var flags = [], output = [], l = array.length, i;
for( i=0; i<l; i++) {
    if( flags[array[i].age]) continue;
    flags[array[i].age] = true;
    output.push(array[i].age);
}

Install ejs if it is not.

npm install ejs

Then after just paste below two lines in your main file. (like app.js, main.js)

app.set('view engine', 'html');

app.engine('html', require('ejs').renderFile);

I figured it out. Need to use echo in PHP instead of return.

<?php 
  $output = some_function();
  echo $output;
?> 

And the jQ:

success: function(data) {
  doSomething(data);
}

This simple example shows how to capture curl output, and use it in a bash script

test.sh

function main
{
  \curl -vs 'http://google.com'  2>&1
  # note: add -o /tmp/ignore.png if you want to ignore binary output, by saving it to a file. 
}

# capture output of curl to a variable
OUT=$(main)

# search output for something using grep.
echo
echo "$OUT" | grep 302 
echo
echo "$OUT" | grep title 

byte[] fileData = null;
using (var binaryReader = new BinaryReader(Request.Files[0].InputStream))
{
    fileData = binaryReader.ReadBytes(Request.Files[0].ContentLength);
}

Label lblSecret = ((Label)e.Row.FindControl("lblSecret"));

Here's an example of creating and using an event with C#

using System;

namespace Event_Example
{
    //First we have to define a delegate that acts as a signature for the
    //function that is ultimately called when the event is triggered.
    //You will notice that the second parameter is of MyEventArgs type.
    //This object will contain information about the triggered event.
    public delegate void MyEventHandler(object source, MyEventArgs e);

    //This is a class which describes the event to the class that recieves it.
    //An EventArgs class must always derive from System.EventArgs.
    public class MyEventArgs : EventArgs
    {
        private string EventInfo;
        public MyEventArgs(string Text)
        {
            EventInfo = Text;
        }
        public string GetInfo()
        {
            return EventInfo;
        }
    }

    //This next class is the one which contains an event and triggers it
    //once an action is performed. For example, lets trigger this event
    //once a variable is incremented over a particular value. Notice the
    //event uses the MyEventHandler delegate to create a signature
    //for the called function.
    public class MyClass
    {
        public event MyEventHandler OnMaximum;
        private int i;
        private int Maximum = 10;
        public int MyValue
        {
            get
            {
                return i;
            }
            set
            {
                if(value <= Maximum)
                {
                    i = value;
                }
                else
                {
                    //To make sure we only trigger the event if a handler is present
                    //we check the event to make sure it's not null.
                    if(OnMaximum != null)
                    {
                        OnMaximum(this, new MyEventArgs("You've entered " +
                            value.ToString() +
                            ", but the maximum is " +
                            Maximum.ToString()));
                    }
                }
            }
        }
    }

    class Program
    {
        //This is the actual method that will be assigned to the event handler
        //within the above class. This is where we perform an action once the
        //event has been triggered.
        static void MaximumReached(object source, MyEventArgs e)
        {
            Console.WriteLine(e.GetInfo());
        }

        static void Main(string[] args)
        {
            //Now lets test the event contained in the above class.
            MyClass MyObject = new MyClass();
            MyObject.OnMaximum += new MyEventHandler(MaximumReached);

            for(int x = 0; x <= 15; x++)
            {
                MyObject.MyValue = x;
            }

            Console.ReadLine();
        }
    }
}

Without seeing your full code, this is impossible to answer with any certainty. The error usually occurs when you are trying to unload a control rather than the form.

Make sure that you don't have the "me" in brackets.

Also if you can post the full code for the userform it would help massively.

Summary

With either string concatenation or string interpolation (via template literals).

Here with JavaScript template literal:

function geoPreview() {
    var lat = document.getElementById("lat").value;
    var long = document.getElementById("long").value;

    window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${lat}&lon=${long}&setLatLon=Set`;
}

Both parameters are unused and can be removed.

Remarks

String Concatenation

Join strings with the + operator:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=" + elemA + "&lon=" + elemB + "&setLatLon=Set";

String Interpolation

For more concise code, use JavaScript template literals to replace expressions with their string representations. Template literals are enclosed by `` and placeholders surrounded with ${}:

window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${elemA}&lon=${elemB}&setLatLon=Set`;

Template literals are available since ECMAScript 2015 (ES6).

Like this?

$string = 'FirstPart SecondPart'
$a,$b = $string.split(' ')
$a
$b

An initial reaction to this would be to ask and ensure that the two object files are being linked together. This is done at the compile stage by compiling both files at the same time:

gcc -o programName a.c b.c

Or if you want to compile separately, it would be:

gcc -c a.c
gcc -c b.c
gcc -o programName a.o b.o

member b of object pointed to by a a->b

You can use CSS to set the opacity, and than use javascript to apply the styles to a certain element in the DOM.

.opClass {
    opacity:0.4;
    filter:alpha(opacity=40); /* For IE8 and earlier */
}

Than use (for example) jQuery to change the style:

$('#element_id').addClass('opClass');

Or with plain javascript, like this:

document.getElementById("element_id").className = "opClass";

I think a 2 step approach is best, because c 2-d arrays are just and array of arrays. The first step is to allocate a single array, then loop through it allocating arrays for each column as you go. This article gives good detail.

I believe the problem is that codecs.BOM_UTF8 is a byte string, not a Unicode string. I suspect the file handler is trying to guess what you really mean based on "I'm meant to be writing Unicode as UTF-8-encoded text, but you've given me a byte string!"

Try writing the Unicode string for the byte order mark (i.e. Unicode U+FEFF) directly, so that the file just encodes that as UTF-8:

import codecs

file = codecs.open("lol", "w", "utf-8")
file.write(u'\ufeff')
file.close()

(That seems to give the right answer - a file with bytes EF BB BF.)

EDIT: S. Lott's suggestion of using "utf-8-sig" as the encoding is a better one than explicitly writing the BOM yourself, but I'll leave this answer here as it explains what was going wrong before.

daniel.gindi's answer above did the trick for me! (+1 daniel) However, I had to make minor adjustments - change the shadowFrame size to be same as view's frame size, and enable user interaction. Here's the updated code:

+ (UIView*)putView:(UIView*)view insideShadowWithColor:(UIColor*)color andRadius:(CGFloat)shadowRadius andOffset:(CGSize)shadowOffset andOpacity:(CGFloat)shadowOpacity
{
    CGRect shadowFrame; // Modify this if needed

    // Modified this line
    shadowFrame.size = CGSizeMake(view.frame.size.width, view.frame.size.height);

    shadowFrame.origin.x = 0.f;
    shadowFrame.origin.y = 0.f;
    UIView * shadow = [[UIView alloc] initWithFrame:shadowFrame];

    // Modified this line
    shadow.userInteractionEnabled = YES;
    shadow.layer.shadowColor = color.CGColor;
    shadow.layer.shadowOffset = shadowOffset;
    shadow.layer.shadowRadius = shadowRadius;
    shadow.layer.masksToBounds = NO;
    shadow.clipsToBounds = NO;
    shadow.layer.shadowOpacity = shadowOpacity;

    [shadow addSubview:view];
    return shadow;
}

I would like to add that in my case, I was trying to add this to a 3rd party view controller, i.e. I did not have direct control over the code. So, here's how I used the function above:

UIView *shadow = [self putView:vc.view

It's an infamous problem: .equals() for arrays is badly broken, just don't use it, ever.

That said, it's not "broken" as in "someone has done it in a really wrong way" — it's just doing what's defined and not what's usually expected. So for purists: it's perfectly fine, and that also means, don't use it, ever.

Now the expected behaviour for equals is to compare data. The default behaviour is to compare the identity, as Object does not have any data (for purists: yes it has, but it's not the point); assumption is, if you need equals in subclasses, you'll implement it. In arrays, there's no implementation for you, so you're not supposed to use it.

So the difference is, Arrays.equals(array1, array2) works as you would expect (i.e. compares content), array1.equals(array2) falls back to Object.equals implementation, which in turn compares identity, and thus better replaced by == (for purists: yes I know about null).

Problem is, even Arrays.equals(array1, array2) will bite you hard if elements of array do not implement equals properly. It's a very naive statement, I know, but there's a very important less-than-obvious case: consider a 2D array.

2D array in Java is an array of arrays, and arrays' equals is broken (or useless if you prefer), so Arrays.equals(array1, array2) will not work as you expect on 2D arrays.

Hope that helps.

Do a cross-domain AJAX call

Your web-service must support method injection in order to do JSONP.

Your code seems fine and it should work if your web services and your web application hosted in the same domain.

When you do a $.ajax with dataType: 'jsonp' meaning that jQuery is actually adding a new parameter to the query URL.

For instance, if your URL is http://10.211.2.219:8080/SampleWebService/sample.do then jQuery will add ?callback={some_random_dynamically_generated_method}.

This method is more kind of a proxy actually attached in window object. This is nothing specific but does look something like this:

window.some_random_dynamically_generated_method = function(actualJsonpData) {
    //here actually has reference to the success function mentioned with $.ajax
    //so it just calls the success method like this: 
    successCallback(actualJsonData);
}

Check the following for more information

Make cross-domain ajax JSONP request with jQuery

You can use regular expressions.

String input = ...
if (input.matches("[^a-zA-Z0-9 ]"))

If your definition of a 'special character' is simply anything that doesn't apply to your other filters that you already have, then you can simply add an else. Also note that you have to use else if in this case:

if(c == ' ') {
    blankCount++;
} else if (Character.isDigit(c)) {
    digitCount++;
} else if (Character.isLetter(c)) {
    letterCount++;
} else { 
  specialcharCount++;
}

For New version of Java JavaPath folder is located

As far as I know, it's the main entry point to your node package (library) for npm. It's needed if your npm project becomes a node package (library) which can be installed via npm by others.

Let's say you have a library with a build/, dist/, or lib/ folder. In this folder, you got the following compiled file for your library:

-lib/
--bundle.js

Then in your package.json, you tell npm how to access the library (node package):

{
  "name": "my-library-name",
  "main": "lib/bundle.js",
  ...
}

After installing the node package with npm to your JS project, you can import functionalities from your bundled bundle.js file:

import { add, subtract } from 'my-library-name';

This holds also true when using Code Splitting (e.g. Webpack) for your library. For instance, this webpack.config.js makes use of code splitting the project into multiple bundles instead of one.

module.exports = {
  entry: {
    main: './src/index.js',
    add: './src/add.js',
    subtract: './src/subtract.js',
  },
  output: {
    path: `${__dirname}/lib`,
    filename: '[name].js',
    library: 'my-library-name',
    libraryTarget: 'umd',
  },
  ...
}

Still, you would define one main entry point to your library in your package.json:

{
  "name": "my-library-name",
  "main": "lib/main.js",
  ...
}

Then when using the library, you can import your files from your main entry point:

import { add, subtract } from 'my-library-name';

However, you can also bypass the main entry point from the package.json and import the code splitted bundles:

import add from 'my-library-name/lib/add';
import subtract from 'my-library-name/lib/subtract';

After all, the main property in your package.json only points to your main entry point file of your library.

unique_ptr
is a smart pointer which owns an object exclusively.

shared_ptr
is a smart pointer for shared ownership. It is both copyable and movable. Multiple smart pointer instances can own the same resource. As soon as the last smart pointer owning the resource goes out of scope, the resource will be freed.

For Java 7, nothing crucial. The OpenJDK project is mostly based on HotSpot source code donated by Sun.

Moreover, OpenJDK was selected to be the reference implementation for Java 7 and is maintained by Oracle engineers.

There's a more detailed answer from 2012 on difference between JVM, JDK, JRE & OpenJDK, which links to an Oracle blog post:

Q: What is the difference between the source code found in the OpenJDK repository, and the code you use to build the Oracle JDK?

A: It is very close - our build process for Oracle JDK releases builds on OpenJDK 7 by adding just a couple of pieces, like the deployment code, which includes Oracle's implementation of the Java Plugin and Java WebStart, as well as some closed source third party components like a graphics rasterizer, some open source third party components, like Rhino, and a few bits and pieces here and there, like additional documentation or third party fonts. Moving forward, our intent is to open source all pieces of the Oracle JDK except those that we consider commercial features such as JRockit Mission Control (not yet available in Oracle JDK), and replace encumbered third party components with open source alternatives to achieve closer parity between the code bases.

The newly Selected answer submitted by Steven Soroka is close, but not complete. The test itself hides the fact that this is not returning a true 404 - it's returning a status of 200 - "success". The original answer was closer, but attempted to render the layout as if no failure had occurred. This fixes everything:

render :text => 'Not Found', :status => '404'

Here's a typical test set of mine for something I expect to return 404, using RSpec and Shoulda matchers:

describe "user view" do
  before do
    get :show, :id => 'nonsense'
  end

  it { should_not assign_to :user }

  it { should respond_with :not_found }
  it { should respond_with_content_type :html }

  it { should_not render_template :show }
  it { should_not render_with_layout }

  it { should_not set_the_flash }
end

This healthy paranoia allowed me to spot the content-type mismatch when everything else looked peachy :) I check for all these elements: assigned variables, response code, response content type, template rendered, layout rendered, flash messages.

I'll skip the content type check on applications that are strictly html...sometimes. After all, "a skeptic checks ALL the drawers" :)

http://dilbert.com/strips/comic/1998-01-20/

FYI: I don't recommend testing for things that are happening in the controller, ie "should_raise". What you care about is the output. My tests above allowed me to try various solutions, and the tests remain the same whether the solution is raising an exception, special rendering, etc.

Even I faced the same problem in my XMPP notification application, receivers message needs to be added back to list view (implemented with ArrayList). When I tried to add the receiver content through MessageListener (separate thread), application quits with above error. I solved this by adding the content to my arraylist & setListviewadapater through runOnUiThread method which is part of Activity class. This solved my problem.

For a direct change, you can use Bootstrap classes in the <a> tag (it won't work in the <div>):

<h4 class="text-center"><a class="text-warning" href="#">Your text</a></h4>

Test-Path can be used with a special syntax:

Test-Path variable:global:foo

This also works for environment variables ($env:foo):

Test-Path env:foo

And for non-global variables (just $foo inline):

Test-Path variable:foo

In jQuery 3 and perhaps earlier versions, the following simpler config also works for individual requests:

$.ajax(
        'https://foo.bar.com,
        {
            dataType: 'json',
            xhrFields: {
                withCredentials: true
            },
            success: successFunc
        }
    );

The full error I was getting in Firefox Dev Tools -> Network tab (in the Security tab for an individual request) was:

An error occurred during a connection to foo.bar.com.SSL peer was unable to negotiate an acceptable set of security parameters.Error code: SSL_ERROR_HANDSHAKE_FAILURE_ALERT

ProjectCodeMeter counts LLOC (logical lines of code) exactly as you described (only effective lines). it integrates into eclipse as external code metrics tool, it's not real-time though, it generates a report.actually it counts many source code metrics such as complexity, arithmetic intricacy, hard coded strings, numeric constants.. even estimates development time in hours.

<ListView android:id="@android:id/list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

this should solve your problem

there are two cause of this exception:

1

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

2

you forgot to add the type parameter to:

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

with:

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

resulting in a compile-time error:

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

Since Bootstrap 4 you can easily change the primary color of your Bootstrap by downloading a simple CSS file on BootstrapColor.net. You don't need to know SASS and the CSS file is ready to use for your website. You can choose the color you want like blue, indigo, purple, pink, red, orange, yellow, green, teal or cyan color.

If some of you, like me, encounter orientation problems I have combined the solutions here with a exif orientation fix

Well, instead of passing Application.Current.MainWindow, just pass a reference to whichever window it is you want: new WindowInteropHelper(this).Handle and so on.

This worked for me:

start /d IEXPLORE.EXE www.google.com
start /d IEXPLORE.EXE www.yahoo.com

But for some reason opened them up in Firefox instead?!?

I tried this but it merely opened up sites in two different windows:

start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.google.com
start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.yahoo.com

I want to put the correct answer in here, just in case others are having this problem like I was. If you hate the ViewBag, fine don't use it, but the real problem with the code in the question is that the same name is being used for both the model property and the selectlist as was pointed out by @RickAndMSFT

Simply changing the name of the DropDownList control should resolve the issue, like so:

@Html.DropDownList("NewsCategoriesSelection", (SelectList)ViewBag.NewsCategoriesID)

It doesn't really have anything to do with using the ViewBag or not using the ViewBag as you can have a name collision with the control regardless.

I also favor the RegEx solution. The code will be much cleaner. I would hesitate to use toLowerCase() in situations where I knew the strings were going to be large, since strings are immutable and would have to be copied. Also, the matches() solution might be confusing because it takes a regular expression as an argument (searching for "Need$le" cold be problematic).

Building on some of the above examples:

public boolean containsIgnoreCase( String haystack, String needle ) {
  if(needle.equals(""))
    return true;
  if(haystack == null || needle == null || haystack .equals(""))
    return false; 

  Pattern p = Pattern.compile(needle,Pattern.CASE_INSENSITIVE+Pattern.LITERAL);
  Matcher m = p.matcher(haystack);
  return m.find();
}

example call: 

String needle = "Need$le";
String haystack = "This is a haystack that might have a need$le in it.";
if( containsIgnoreCase( haystack, needle) ) {
  System.out.println( "Found " + needle + " within " + haystack + "." );
}

(Note: you might want to handle NULL and empty strings differently depending on your needs. I think they way I have it is closer to the Java spec for strings.)

Speed critical solutions could include iterating through the haystack character by character looking for the first character of the needle. When the first character is matched (case insenstively), begin iterating through the needle character by character, looking for the corresponding character in the haystack and returning "true" if all characters get matched. If a non-matched character is encountered, resume iteration through the haystack at the next character, returning "false" if a position > haystack.length() - needle.length() is reached.

First go to Resource View (from menu: View --> Other Window --> Resource View). Then in Resource View navigate through resources, if any. If there is already a resource of Icon type, added by Visual Studio, then open and edit it. Otherwise right-click and select Add Resource, and then add a new icon.

Use the embedded image editor in order to edit the existing or new icon. Note that an icon can include several types (sizes), selected from Image menu.

Then compile your project and see the effect.

It is possible to pass arrays to functions, and there are no special requirements for dealing with them. Are you sure that the array you are passing to to your function actually has an element at [0]?

apt–get: command not found

For Debian based Linux distributions:

Try to use sudo apt install <package> instead of the usual sudo apt-get install <package>

From man apt

apt provides a high-level commandline interface for the package management system. It is intended as an end user interface and enables some options better suited for interactive usage by default compared to more specialized APT tools like apt-get(8) and apt-cache(8).

Yahoo's api provides a CSV dump:

Example: http://finance.yahoo.com/d/quotes.csv?s=msft&f=price

I'm not sure if it is documented or not, but this code sample should showcase all of the features (namely the stat types [parameter f in the query string]. I'm sure you can find documentation (official or not) if you search for it.

Edit

I found some unofficial documentation:

http://ilmusaham.wordpress.com/tag/stock-yahoo-data/

I know this is too late for sure, but, this could help someone as well.

In my case, i found that the source file is being used by another process which was restricting from copying to the destination. I found that by using command prompt ( just copy paste the post build command to the command prompt and executed gave me the error info).

Make sure that you can copy from the command prompt,

A build, as Makefile understands it, consists of a lot of targets. For example, to build a project you might need

1. Build file1.o out of file1.c
2. Build file2.o out of file2.c
3. Build file3.o out of file3.c
4. Build executable1 out of file1.o and file3.o
5. Build executable2 out of file2.o

If you implemented this workflow with makefile, you could make each of the targets separately. For example, if you wrote

make file1.o

it would only build that file, if necessary.

The name of all is not fixed. It's just a conventional name; all target denotes that if you invoke it, make will build all what's needed to make a complete build. This is usually a dummy target, which doesn't create any files, but merely depends on the other files. For the example above, building all necessary is building executables, the other files being pulled in as dependencies. So in the makefile it looks like this:

all: executable1 executable2

all target is usually the first in the makefile, since if you just write make in command line, without specifying the target, it will build the first target. And you expect it to be all.

all is usually also a .PHONY target. Learn more here.

There is another way,

j3 = j2 > 4; print(j2[j3])

tested in 3.x

There is no direct shortcut for such operation in IntelliJ IDEA 14 but you can install the plugin and set it the keyboard shortcut to the function that called "Scroll From Source" in keymap settings.

They're different characters. \r is carriage return, and \n is line feed.

On "old" printers, \r sent the print head back to the start of the line, and \n advanced the paper by one line. Both were therefore necessary to start printing on the next line.

Obviously that's somewhat irrelevant now, although depending on the console you may still be able to use \r to move to the start of the line and overwrite the existing text.

More importantly, Unix tends to use \n as a line separator; Windows tends to use \r\n as a line separator and Macs (up to OS 9) used to use \r as the line separator. (Mac OS X is Unix-y, so uses \n instead; there may be some compatibility situations where \r is used instead though.)

For more information, see the Wikipedia newline article.

EDIT: This is language-sensitive. In C# and Java, for example, \n always means Unicode U+000A, which is defined as line feed. In C and C++ the water is somewhat muddier, as the meaning is platform-specific. See comments for details.

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

Before you start make sure your have read and understood this note from Google! This tutorial makes using gtest easy, but may introduce nasty bugs.

1. Get the googletest framework

wget https://github.com/google/googletest/archive/release-1.8.0.tar.gz

Or get it by hand. I won't maintain this little How-to, so if you stumbled upon it and the links are outdated, feel free to edit it.

2. Unpack and build google test

tar xf release-1.8.0.tar.gz
cd googletest-release-1.8.0
cmake -DBUILD_SHARED_LIBS=ON .
make

3. "Install" the headers and libs on your system.

This step might differ from distro to distro, so make sure you copy the headers and libs in the correct directory. I accomplished this by checking where Debians former gtest libs were located. But I'm sure there are better ways to do this. Note: make install is dangerous and not supported

sudo cp -a googletest/include/gtest /usr/include
sudo cp -a googlemock/gtest/libgtest_main.so googlemock/gtest/libgtest.so /usr/lib/

4. Update the cache of the linker

... and check if the GNU Linker knows the libs

sudo ldconfig -v | grep gtest

If the output looks like this:

libgtest.so.0 -> libgtest.so.0.0.0
libgtest_main.so.0 -> libgtest_main.so.0.0.0

then everything is fine.

gTestframework is now ready to use. Just don't forget to link your project against the library by setting -lgtest as linker flag and optionally, if you did not write your own test mainroutine, the explicit -lgtest_main flag.

From here on you might want to go to Googles documentation, and the old docs about the framework to learn how it works. Happy coding!

Edit: This works for OS X too! See "How to properly setup googleTest on OS X"

I had to restart Android Studio for changing the sdk after installing a new one. Then Android Studio asked me for configuring my SDK and let me do it.

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

ps -elf doesn't seem to show the PID. I recommend using instead:

ps -ld | grep foo
gdb -p PID

Another way:

export default class Archive extends React.Component { 

  saySomething = (something) => {
    console.log(something);
  }

  handleClick = (e) => {
    this.saySomething("element clicked");
  }

  componentDidMount() {
    this.saySomething("component did mount");
  }

  render() {
    return <button onClick={this.handleClick} value="Click me" />;
  }
}

In this format you don't need to use bind
