This way should cover a situation of concurrency when the function is called again while is still executing (and items need used only once):

 while (list.Count > 0)
 {
    string Item = list[0];
    list.RemoveAt(0);
 
    // do here what you need to do with item
 
 } 
 

If the function get called while is still executing items will not reiterate from the first again as they get deleted as soon as they get used. Should not affect performance much for small lists.

Use SemaphoreSlim.WaitAsync method.

 await mySemaphoreSlim.WaitAsync();
 try {
     await Stuff();
 } finally {
     mySemaphoreSlim.Release();
 }

First of all, you need to login as root and than go to /etc directory and execute some commands which are given below.

[root@localhost~]# cd /etc
[root@localhost /etc]# vi sudoers

and enter this line at the end

kundan ALL=NOPASSWD: ALL

where kundan is the username and than save it. and then try to transfer the file and add sudo as a prefix to the command you want to execute:

sudo cp hello.txt /home/rahul/program/

where rahul is the second user in the same server.

You had two problems:

1) The order in which you included the HTML. Try changing the dropdown from "onLoad" to "no wrap - head" in the JavaScript settings of your fiddle.

2) Your function prints the values. What you're actually after is the text

x.options[i].text; instead of x.options[i].value;

Use AsNoTracking() where you are getting your query.

  var result = dbcontext.YourModel.AsNoTracking().Where(x => x.aID == aID && x.UserID==userID).Count();

I ended up doing the following and it works.

public static string Serialize(object obj)
{
    using (MemoryStream memoryStream = new MemoryStream())
    {
        DataContractSerializer serializer = new DataContractSerializer(obj.GetType());
        serializer.WriteObject(memoryStream, obj);
        return Encoding.UTF8.GetString(memoryStream.ToArray());
    }
}

public static object Deserialize(string xml, Type toType)
{
    using (MemoryStream memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(xml)))
    {
        XmlDictionaryReader reader = XmlDictionaryReader.CreateTextReader(memoryStream, Encoding.UTF8, new XmlDictionaryReaderQuotas(), null);
        DataContractSerializer serializer = new DataContractSerializer(toType);
        return serializer.ReadObject(reader);
    }
}

It seems that the major problem was in the Serialize function when calling stream.GetBuffer(). Calling stream.ToArray() appears to work.

set -x enables a mode of the shell where all executed commands are printed to the terminal. In your case it's clearly used for debugging, which is a typical use case for set -x: printing every command as it is executed may help you to visualize the control flow of the script if it is not functioning as expected.

set +x disables it.

I was not satisfied, so I finally used this:

>>> a=numpy.array([[1,2,3],[4,5,6]])
>>> a
array([[1, 2, 3],
       [4, 5, 6]])

>>> tuple(a.reshape(1, -1)[0])
(1, 2, 3, 4, 5, 6)

I don't know if it's quicker, but it looks more effective ;)

You can try max-height: 70px; See if that works.

Actually you dont need to call document.getElementById() function to get access to your div.

You can use this object directly by id:

text = test.textContent || test.innerText;
alert(text);

After data.clear() it will definitely start again from the zero index.

Use:

List<String> x = new ArrayList<>(Arrays.asList("xyz", "abc"));

If you don't want to add new elements to the list later, you can also use (Arrays.asList returns a fixed-size list):

List<String> x = Arrays.asList("xyz", "abc");

Note: you can also use a static import if you like, then it looks like this:

import static java.util.Arrays.asList;

...

List<String> x = new ArrayList<>(asList("xyz", "abc"));

or

List<String> x = asList("xyz", "abc");

Try

let a = document.createElement('a');
a.href = "data:application/octet-stream,"+encodeURIComponent("My DATA");
a.download = 'abc.txt';
a.click();

Update

2020.06.14 I upgrade Chrome to 83.0 and above SO snippet stop works (reason: sandbox security restrictions) - but JSFiddle version works - here

I always do the following whenever I get such error:

// remove node_modules/
rm -rf node_modules/
// install node_modules/ again
npm install // or, yarn

and then start the project

npm start //or, yarn start

It works fine after re-installing node_modules. But I don't know if it's good practice.

function yourFunction($var1, $var2, $optional = Null){
   ... code
}

You can make a regular function and then add your optional variables by giving them a default Null value.

A Null is still a value, if you don't call the function with a value for that variable, it won't be empty so no error.

There are a bunch of different reasons for the "Too Many Connections" error.

Check out this FAQ page on MySQL.com: http://dev.mysql.com/doc/refman/5.5/en/too-many-connections.html

Check your my.cnf file for "max_connections". If none exist try:

[mysqld]
set-variable=max_connections=250

However the default is 151, so you should be okay.

If you are on a shared host, it might be that other users are taking up too many connections.

Other problems to look out for is the use of persistent connections and running out of diskspace.

Background images sure can present data! In fact, this is often recommended where presenting visual icons is more compact and user-friendly than an equivalent list of text blurbs. Any use of image sprites can benefit from this approach.

It is quite common for hotel listings icons to display amenities. Imagine a page which listed 50 hotel and each hotel had 10 amenities. A CSS Sprite would be perfect for this sort of thing -- better user experience because it's faster. But how do you implement ALT tags for these images? Example site.

The answer is that they don't use alt text at all, but instead use the title attribute on the containing div.

HTML

<div class="hotwire-fitness" title="Fitness Centre"></div>

CSS

.hotwire-fitness {
    float: left;
    margin-right: 5px;
    background: url(/prostyle/images/new_amenities.png) -71px 0;
    width: 21px;
    height: 21px;
}

According to the W3C (see links above), the title attribute serves much of the same purpose as the alt attribute

Title

Values of the title attribute may be rendered by user agents in a variety of ways. For instance, visual browsers frequently display the title as a "tool tip" (a short message that appears when the pointing device pauses over an object). Audio user agents may speak the title information in a similar context. For example, setting the attribute on a link allows user agents (visual and non-visual) to tell users about the nature of the linked resource:

alt

The alt attribute is defined in a set of tags (namely, img, area and optionally for input and applet) to allow you to provide a text equivalent for the object.

A text equivalent brings the following benefits to your website and its visitors in the following common situations:

• nowadays, Web browsers are available in a very wide variety of platforms with very different capacities; some cannot display images at all or only a restricted set of type of images; some can be configured to not load images. If your code has the alt attribute set in its images, most of these browsers will display the description you gave instead of the images
• some of your visitors cannot see images, be they blind, color-blind, low-sighted; the alt attribute is of great help for those people that can rely on it to have a good idea of what's on your page
• search engine bots belong to the two above categories: if you want your website to be indexed as well as it deserves, use the alt attribute to make sure that they won't miss important sections of your pages.

Here are some more tests

True if string is not empty:

[ -n "$var" ]
[[ -n $var ]]
test -n "$var"
[ "$var" ]
[[ $var ]]
(( ${#var} ))
let ${#var}
test "$var"

True if string is empty:

[ -z "$var" ]
[[ -z $var ]]
test -z "$var"
! [ "$var" ]
! [[ $var ]]
! (( ${#var} ))
! let ${#var}
! test "$var"

The script tag to the api has changed recently. Use something like this to query the Geocoding API and get the JSON object back

<script type="text/javascript" src="https://maps.googleapis.com/maps/api/geocode/json?address=THE_ADDRESS_YOU_WANT_TO_GEOCODE&key=YOUR_API_KEY"></script>

The address could be something like

1600+Amphitheatre+Parkway,+Mountain+View,+CA (URI Encoded; you should Google it. Very useful)

or simply

1600 Amphitheatre Parkway, Mountain View, CA

By entering this address https://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&key=YOUR_API_KEY inside the browser, along with my API Key, I get back a JSON object which contains the Latitude & Longitude for the city of Moutain view, CA.

Web Frameworks such like AngularJS allow us to perform these queries with ease.

You may need:

Object.keys(JSON[0]);

To get something like:

[ 'amount', 'job', 'month', 'year' ]

Note: Your JSON is invalid.

Try to look Create constants using a "settings" module? and Can I prevent modifying an object in Python?

Another one useful link: http://code.activestate.com/recipes/65207-constants-in-python/ tells us about the following option:

from copy import deepcopy

class const(object):

    def __setattr__(self, name, value):
        if self.__dict__.has_key(name):
            print 'NO WAY this is a const' # put here anything you want(throw exc and etc)
            return deepcopy(self.__dict__[name])
        self.__dict__[name] = value

    def __getattr__(self, name, value):
        if self.__dict__.has_key(name):
            return deepcopy(self.__dict__[name])

    def __delattr__(self, item):
        if self.__dict__.has_key(item):
            print 'NOOOOO' # throw exception if needed

CONST = const()
CONST.Constant1 = 111
CONST.Constant1 = 12
print a.Constant1 # 111
CONST.Constant2 = 'tst'
CONST.Constant2 = 'tst1'
print a.Constant2 # 'tst'

So you could create a class like this and then import it from you contants.py module. This will allow you to be sure that value would not be changed, deleted.

Now Update word-wrap is replace by :

overflow-wrap:break-word;

Compatible old navigator and css 3 it's good alternative !

it's evolution of word-wrap ( since 2012... )

Update August 2020

As mentioned originally in this answer by SoBeRich, and in my own answer, as of git 2.4.x

git push --atomic origin <branch name> <tag>

(Note: this actually work with HTTPS only with Git 2.24)

Update May 2015

As of git 2.4.1, you can do

git config --global push.followTags true

If set to true enable --follow-tags option by default.
You may override this configuration at time of push by specifying --no-follow-tags.

As noted in this thread by Matt Rogers answering Wes Hurd:

--follow-tags only pushes annotated tags.

git tag -a -m "I'm an annotation" <tagname>

That would be pushed (as opposed to git tag <tagname>, a lightweight tag, which would not be pushed, as I mentioned here)

Update April 2013

Since git 1.8.3 (April 22d, 2013), you no longer have to do 2 commands to push branches, and then to push tags:

The new "--follow-tags" option tells "git push" to push relevant annotated tags when pushing branches out.

You can now try, when pushing new commits:

git push --follow-tags

That won't push all the local tags though, only the one referenced by commits which are pushed with the git push.

Git 2.4.1+ (Q2 2015) will introduce the option push.followTags: see "How to make “git push” include tags within a branch?".

Original answer, September 2010

The nuclear option would be git push --mirror, which will push all refs under refs/.

You can also push just one tag with your current branch commit:

git push origin : v1.0.0 

You can combine the --tags option with a refspec like:

git push origin --tags :

(since --tags means: All refs under refs/tags are pushed, in addition to refspecs explicitly listed on the command line)

You also have this entry "Pushing branches and tags with a single "git push" invocation"

A handy tip was just posted to the Git mailing list by Zoltán Füzesi:

I use .git/config to solve this:

[remote "origin"]
    url = ...
    fetch = +refs/heads/*:refs/remotes/origin/*
    push = +refs/heads/*
    push = +refs/tags/*

With these lines added git push origin will upload all your branches and tags. If you want to upload only some of them, you can enumerate them.

Haven't tried it myself yet, but it looks like it might be useful until some other way of pushing branches and tags at the same time is added to git push.
On the other hand, I don't mind typing:

$ git push && git push --tags

Beware, as commented by Aseem Kishore

push = +refs/heads/* will force-pushes all your branches.

This bit me just now, so FYI.

René Scheibe adds this interesting comment:

The --follow-tags parameter is misleading as only tags under .git/refs/tags are considered.
If git gc is run, tags are moved from .git/refs/tags to .git/packed-refs. Afterwards git push --follow-tags ... does not work as expected anymore.

@PaulR posted this as a comment, but people should view it as an answer (and this answer works best for my needs):

sed -i 's/abc/xyz/g' xa*

This will work for a moderate amount of files, probably on the order of tens, but probably not on the order of millions.

<input type="name" placeholder="First Name" title="First Name" />

title="First Name" solves my proble. it worked with bootstrap.

As Andrie said, system.time() works fine. For short function I prefer to put replicate() in it:

system.time( replicate(10000, myfunction(with,arguments) ) )

hope this will help you

SELECT COLUMN_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_name = 'tbl_name'
AND table_schema = 'db_name'
AND column_name = 'column_name'

or

IF NOT EXISTS(

    ADD COLUMN `new_column` TINYINT(1) NOT NULL DEFAULT 1;;

END IF;
END;
//

CALL addcol();

DROP PROCEDURE addcol;

SCP answer

The OP mentioned SCP, so here's that.

As others have pointed out, SFTP is a confusing since the upload syntax is completely different from the download syntax. It gets marginally easier to remember if you use the same form:

echo 'put LOCALPATH REMOTEPATH' | sftp USER@HOST
echo 'get REMOTEPATH LOCALPATH' | sftp USER@HOST

In reality, this is still a mess, and is why people still use "outdated" commands such as SCP:

scp USER@HOST:REMOTEPATH LOCALPATH
scp LOCALPATH USER@HOST:REMOTEPATH

SCP is secure but dated. It has some bugs that will never be fixed, namely crashing if the server's .bash_profile emits a message. However, in terms of usability, the devs were years ahead.

Here is a jsfiddle so you can see an example of this working.

HTML code:

<div class="circle"></div>

CSS code:

.circle {_x000D_
        /*This creates a 1px solid red border around your element(div) */_x000D_
        border:1px solid red;_x000D_
        background-color: #FFFFFF;_x000D_
        height: 100px;_x000D_
        /* border-radius 50% will make it fully rounded. */_x000D_
        border-radius: 50%;_x000D_
        -moz-border-radius:50%;_x000D_
        -webkit-border-radius: 50%;_x000D_
        width: 100px;_x000D_
    }

<div class='circle'></div>

Requirements:

• When the date is further away, use the standard moment().fromNow() functionality.
• When the date is closer, show "today", "yesterday", "tomorrow", etc.

Solution:

// call this function, passing-in your date
function dateToFromNowDaily( myDate ) {

    // get from-now for this date
    var fromNow = moment( myDate ).fromNow();

    // ensure the date is displayed with today and yesterday
    return moment( myDate ).calendar( null, {
        // when the date is closer, specify custom values
        lastWeek: '[Last] dddd',
        lastDay:  '[Yesterday]',
        sameDay:  '[Today]',
        nextDay:  '[Tomorrow]',
        nextWeek: 'dddd',
        // when the date is further away, use from-now functionality             
        sameElse: function () {
            return "[" + fromNow + "]";
        }
    });
}

NB: From version 2.14.0, the formats argument to the calendar function can be a callback, see http://momentjs.com/docs/#/displaying/calendar-time/.

Disabling/setting read-only for all children controls in a container control. I needed to do this because some of the children controls were containers themselves.

public static void SetReadOnly(Control ctrl, bool readOnly)
{
    //set the control read only
    SetControlReadOnly(ctrl, readOnly);

    if (ctrl.Controls != null && ctrl.Controls.Count > 0)
    {
        //recursively loop through all child controls
        foreach (Control c in ctrl.Controls)
            SetReadOnly(c, readOnly);
    }
}

As others have said you're subtracting from the numeric values returned from methods like date.getDate(), you need to reset those values on your date variable. I've created a method below that will do this for you. It creates a date using new Date() which will initialize with the current date, then sets the date, month, and year according to the values passed in. For example, if you want to go back 6 days then pass in -6 like so var newdate = createDate(-6,0,0). If you don't want to set a value pass in a zero (or you could set default values). The method will return the new date for you (tested in Chrome and Firefox).

function createDate(days, months, years) {
        var date = new Date(); 
        date.setDate(date.getDate() + days);
        date.setMonth(date.getMonth() + months);
        date.setFullYear(date.getFullYear() + years);
        return date;    
    }

To Disable scroll use this

webView.setOnTouchListener(new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) 
    {
        return (event.getAction() == MotionEvent.ACTION_MOVE);
    }
});

If the external configuration file is also valid batch file, you can just use:

call externalconfig.bat

inside your script. Try creating following a.bat:

@echo off
call b.bat
echo %MYVAR%

and b.bat:

set MYVAR=test

Running a.bat should generate output:

test

So use the typeof operator to determine if the second parameter is an Array or function.

This can give some suggestions: http://www.planetpdf.com/developer/article.asp?ContentID=testing_for_object_types_in_ja

I am not certain if this is work or homework, so I don't want to give you the answer at the moment, but the typeof will help you determine it.

Shallow copy: Copies the member values from one object into another.

Deep Copy:    Copies the member values from one object into another.
                     Any pointer objects are duplicated and Deep Copied.

Example:

class String
{
     int   size;
     char* data;
};

String  s1("Ace");   // s1.size = 3 s1.data=0x0000F000

String  s2 = shallowCopy(s1);
 // s2.size =3 s2.data = 0X0000F000
String  s3 = deepCopy(s1);
 // s3.size =3 s3.data = 0x0000F00F
 //                      (With Ace copied to this location.)

You could look at "XpathNavigator.Evaluate" I have used this to process mathematical expressions for my GridView and it works fine for me.

Here is the code I used for my program:

public static double Evaluate(string expression)
{
    return (double)new System.Xml.XPath.XPathDocument
    (new StringReader("<r/>")).CreateNavigator().Evaluate
    (string.Format("number({0})", new
    System.Text.RegularExpressions.Regex(@"([\+\-\*])")
    .Replace(expression, " ${1} ")
    .Replace("/", " div ")
    .Replace("%", " mod ")));
}

you need only set default value to parameters(you do not need the Route attribute):

public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

You can do it by putting your images on a fixed path (for example: /var/images, or c:\images), add a setting in your application settings (represented in my example by the Settings.class), and load them like that, in a HttpServlet of yours:

String filename = Settings.getValue("images.path") + request.getParameter("imageName")
FileInputStream fis = new FileInputStream(filename);

int b = 0;
while ((b = fis.read()) != -1) {
        response.getOutputStream().write(b);
}

Or if you want to manipulate the image:

String filename = Settings.getValue("images.path") + request.getParameter("imageName")
File imageFile = new File(filename);
BufferedImage image = ImageIO.read(imageFile);
ImageIO.write(image, "image/png", response.getOutputStream());

then the html code would be <img src="imageServlet?imageName=myimage.png" />

Of course you should think of serving different content types - "image/jpeg", for example based on the file extension. Also you should provide some caching.

In addition you could use this servlet for quality rescaling of your images, by providing width and height parameters as arguments, and using image.getScaledInstance(w, h, Image.SCALE_SMOOTH), considering performance, of course.

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

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

A very general command prompt how to for java is

javac mainjava.java
java mainjava

You'll very often see people doing

javac *.java
java mainjava

As for the subclass problem that's probably occurring because a path is missing from your class path, the -c flag I believe is used to set that.

For some strange reason the SelectElement for webdriver (version 2.25.1.0) does not properly work with the firefoxdriver (Firefox 15). Sometimes it may not select an option from a dropdownlist. It does, however, seem to work with the chromedriver... This is a link to the chromedriver... just drop it in the bin dir.

There is a dynamic comparison chart over at the versioncontrolblog where you can compare several different version control systems.

Kibana doesn't have a log file by default. but you can set it up using log_file Kibana server property - https://www.elastic.co/guide/en/kibana/current/kibana-server-properties.html

I use this function to calculate cpu usage. Hope it can help you.

private float readUsage() {
    try {
        RandomAccessFile reader = new RandomAccessFile("/proc/stat", "r");
        String load = reader.readLine();

        String[] toks = load.split(" +");  // Split on one or more spaces

        long idle1 = Long.parseLong(toks[4]);
        long cpu1 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
              + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        try {
            Thread.sleep(360);
        } catch (Exception e) {}

        reader.seek(0);
        load = reader.readLine();
        reader.close();

        toks = load.split(" +");

        long idle2 = Long.parseLong(toks[4]);
        long cpu2 = Long.parseLong(toks[2]) + Long.parseLong(toks[3]) + Long.parseLong(toks[5])
            + Long.parseLong(toks[6]) + Long.parseLong(toks[7]) + Long.parseLong(toks[8]);

        return (float)(cpu2 - cpu1) / ((cpu2 + idle2) - (cpu1 + idle1));

    } catch (IOException ex) {
        ex.printStackTrace();
    }

    return 0;
} 

The easiest way would be:

#yourInput::placeholder {
    color: red;/*As an example*/
}
/* if that would not work, you can always try styling the attribute itself: */
#myInput[placeholder] {
    color: red;
}

I think you can use the TimeZoneInfo....to convert the datetime....

    static void Main(string[] args)
    {
        long time = 1310522400000;
        DateTime dt_1970 = new DateTime(1970, 1, 1);
        long tricks_1970 = dt_1970.Ticks;
        long time_tricks = tricks_1970 + time * 10000;
        DateTime dt = new DateTime(time_tricks);

        Console.WriteLine(dt.ToShortDateString()); // result : 7/13
        dt = TimeZoneInfo.ConvertTimeToUtc(dt);

        Console.WriteLine(dt.ToShortDateString());  // result : 7/12
        Console.Read();
    }

Under Project->Properties->Debug, you should see a box for Command line arguments (This is in C# 2010, but it should basically be the same place)

Try this:

<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/rel_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >

<ImageView
    android:id="@+id/ImageView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src=//source of image />

<TextView
    android:id="@+id/ImageViewText"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignLeft="@id/ImageView"
    android:layout_alignTop="@id/ImageView"
    android:layout_alignRight="@id/ImageView"
    android:layout_alignBottom="@id/ImageView"
    android:text=//u r text here
    android:gravity="center"
    />

Hope this could help you.

To use internal storage for the application, you don't need permission, but you may need to use: File directory = getApplication().getCacheDir(); to get the allowed directory for the app.

Or:
getCashDir(); <-- should work
context.getCashDir(); (if in a broadcast receiver)
getDataDir(); <--Api 24

Update: Rather use flex.

If you want precision this is the way to go.

Short Answer:

• orElse() will always call the given function whether you want it or not, regardless of Optional.isPresent() value
• orElseGet() will only call the given function when the Optional.isPresent() == false

In real code, you might want to consider the second approach when the required resource is expensive to get.

// Always get heavy resource
getResource(resourceId).orElse(getHeavyResource()); 

// Get heavy resource when required.
getResource(resourceId).orElseGet(() -> getHeavyResource()) 

For more details, consider the following example with this function:

public Optional<String> findMyPhone(int phoneId)

The difference is as below:

                           X : buyNewExpensivePhone() called

+——————————————————————————————————————————————————————————————————+——————————————+
|           Optional.isPresent()                                   | true | false |
+——————————————————————————————————————————————————————————————————+——————————————+
| findMyPhone(int phoneId).orElse(buyNewExpensivePhone())          |   X  |   X   |
+——————————————————————————————————————————————————————————————————+——————————————+
| findMyPhone(int phoneId).orElseGet(() -> buyNewExpensivePhone()) |      |   X   |
+——————————————————————————————————————————————————————————————————+——————————————+

When optional.isPresent() == false, there is no difference between two ways. However, when optional.isPresent() == true, orElse() always calls the subsequent function whether you want it or not.

Finally, the test case used is as below:

Result:

------------- Scenario 1 - orElse() --------------------
  1.1. Optional.isPresent() == true (Redundant call)
    Going to a very far store to buy a new expensive phone
    Used phone: MyCheapPhone

  1.2. Optional.isPresent() == false
    Going to a very far store to buy a new expensive phone
    Used phone: NewExpensivePhone

------------- Scenario 2 - orElseGet() --------------------
  2.1. Optional.isPresent() == true
    Used phone: MyCheapPhone

  2.2. Optional.isPresent() == false
    Going to a very far store to buy a new expensive phone
    Used phone: NewExpensivePhone

Code:

public class TestOptional {
    public Optional<String> findMyPhone(int phoneId) {
        return phoneId == 10
                ? Optional.of("MyCheapPhone")
                : Optional.empty();
    }

    public String buyNewExpensivePhone() {
        System.out.println("\tGoing to a very far store to buy a new expensive phone");
        return "NewExpensivePhone";
    }


    public static void main(String[] args) {
        TestOptional test = new TestOptional();
        String phone;
        System.out.println("------------- Scenario 1 - orElse() --------------------");
        System.out.println("  1.1. Optional.isPresent() == true (Redundant call)");
        phone = test.findMyPhone(10).orElse(test.buyNewExpensivePhone());
        System.out.println("\tUsed phone: " + phone + "\n");

        System.out.println("  1.2. Optional.isPresent() == false");
        phone = test.findMyPhone(-1).orElse(test.buyNewExpensivePhone());
        System.out.println("\tUsed phone: " + phone + "\n");

        System.out.println("------------- Scenario 2 - orElseGet() --------------------");
        System.out.println("  2.1. Optional.isPresent() == true");
        // Can be written as test::buyNewExpensivePhone
        phone = test.findMyPhone(10).orElseGet(() -> test.buyNewExpensivePhone());
        System.out.println("\tUsed phone: " + phone + "\n");

        System.out.println("  2.2. Optional.isPresent() == false");
        phone = test.findMyPhone(-1).orElseGet(() -> test.buyNewExpensivePhone());
        System.out.println("\tUsed phone: " + phone + "\n");
    }
}

I have had a similar issue in iOS 8, 9 and 10 and the info above couldn't fix it, however I did discover a solution after a day of working on this. Granted it won't work for everyone but in my case my items were stacked in a column and had 0 height when it should have been content height. Switching the css to be row and wrap fixed the issue. This only works if you have a single item and they are stacked but since it took me a day to find this out I thought I should share my fix!

.wrapper {
    flex-direction: column; // <-- Remove this line
    flex-direction: row; // <-- replace it with
    flex-wrap: wrap; // <-- Add wrapping
}

.item {
    width: 100%;
}

Take a look at the very recently released SSHD, which is based on the Apache MINA project.

DateTime.UtcNow.ToString("s", System.Globalization.CultureInfo.InvariantCulture) should give you what you are looking for as the "s" format specifier is described as a sortable date/time pattern; conforms to ISO 8601.

EDIT: To get the additional Z at the end as the OP requires, use "o" instead of "s".

Because there is no requirement for JavaScript it simplifies the situation significantly. You essentially need to focus on the second CSS rule, which contains the conditions for ensuring that the head of the table remains of the top no matter the scroll space.

To elaborate on each of the rules in detail. position is meant to indicate to the browser that the head object, its row, and its cells all need to stick to the top. This necessarily needs to be accompanied by top, which specifies to the browser that the head will stick to the top of the page or viewport. Additionally, you can add z-index to ensure that the content of the head always remains on the top.

The background colour is merely to illustrate the point. You do not need to use any additional JavaScript to get this effect. This is supported in most major browsers after 2016.

You can always escape the reserved keyword if you still want to make your query work!!

Just replace end with `end`

Here is the list of reserved keywords https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL

CREATE EXTERNAL TABLE moveProjects (cid string, `end` string, category string)
STORED BY 'org.apache.hadoop.hive.dynamodb.DynamoDBStorageHandler'
TBLPROPERTIES ("dynamodb.table.name" = "Projects",
    "dynamodb.column.mapping" = "cid:cid,end:end,category:category");

The new urllib3 library has a nice documentation here
In order to get your desired result you shuld follow that:

Import urllib3
from bs4 import BeautifulSoup

url = 'http://www.thefamouspeople.com/singers.php'

http = urllib3.PoolManager()
response = http.request('GET', url)
soup = BeautifulSoup(response.data.decode('utf-8'))

The "decode utf-8" part is optional. It worked without it when i tried, but i posted the option anyway.

There's a short overview at MinGW-w64 Wiki:

Why doesn't mingw-w64 gcc support Dwarf-2 Exception Handling?

The Dwarf-2 EH implementation for Windows is not designed at all to work under 64-bit Windows applications. In win32 mode, the exception unwind handler cannot propagate through non-dw2 aware code, this means that any exception going through any non-dw2 aware "foreign frames" code will fail, including Windows system DLLs and DLLs built with Visual Studio. Dwarf-2 unwinding code in gcc inspects the x86 unwinding assembly and is unable to proceed without other dwarf-2 unwind information.

The SetJump LongJump method of exception handling works for most cases on both win32 and win64, except for general protection faults. Structured exception handling support in gcc is being developed to overcome the weaknesses of dw2 and sjlj. On win64, the unwind-information are placed in xdata-section and there is the .pdata (function descriptor table) instead of the stack. For win32, the chain of handlers are on stack and need to be saved/restored by real executed code.

GCC GNU about Exception Handling:

GCC supports two methods for exception handling (EH):

• DWARF-2 (DW2) EH, which requires the use of DWARF-2 (or DWARF-3) debugging information. DW-2 EH can cause executables to be slightly bloated because large call stack unwinding tables have to be included in th executables.
• A method based on setjmp/longjmp (SJLJ). SJLJ-based EH is much slower than DW2 EH (penalising even normal execution when no exceptions are thrown), but can work across code that has not been compiled with GCC or that does not have call-stack unwinding information.

[...]

Structured Exception Handling (SEH)

Windows uses its own exception handling mechanism known as Structured Exception Handling (SEH). [...] Unfortunately, GCC does not support SEH yet. [...]

I installed Oracle Express Edition and I have the same error. One of the possible reason that is maybe your user does not have permission to open this shortcut. Here is how I solved the problem.

1. Right-click the shortcut and select the properties.

2. Now click the Open File Location. Now you will see there is a Get_Started shortcut.

3. Now right-click the Get_Started and select the properties. Then select your user and give permission to your user in the security tab.

setAllowUrlEncodedSlash(true) didn't work for me. Still internal method isNormalized return false when having double slash.

I replaced StrictHttpFirewall with DefaultHttpFirewall by having the following code only:

Working well for me.
Any risk by using DefaultHttpFirewall?

It really depends on many settings, on both the audio and video side of things. If you follow the compression-settings of this video, then it's approximately 3GB per hour. If you have a Mac, I would definitely recommend using 'Compressor' as it is fairly easy to use and works flawless.

As far as storage is concerned, if you're looking at 100hrs / 300GB, I would definitely go with an external hard drive. Video files are so huge, that they (even if they don't totally fill up your hard disk) really do confuse your computer. Make sure to make some time for compressing the whole thing because it takes hours and hours and hours.... for 100 hrs worth of footage, it'll take days.

You can activate JVM's debugging capability when starting up the java command with a special option:

java -agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=y -jar path/to/some/war/or/jar.jar

Starting up jar.jar like that on the command line will:

• put this JVM instance in the role of a server (server=y) listening on port 8000 (address=8000)
• write Listening for transport dt_socket at address: 8000 to stdout and
• then pause the application (suspend=y) until some debugger connects. The debugger acts as the client in this scenario.

Common options for selecting a debugger are:

• Eclipse Debugger: Under Run -> Debug Configurations... -> select Remote Java Application -> click the New launch configuration button. Provide an arbitrary Name for this debug configuration, Connection Type: Standard (Socket Attach) and as Connection Properties the entries Host: localhost, Port: 8000. Apply the Changes and click Debug. At the moment the Eclipse Debugger has successfully connected to the JVM, jar.jar should begin executing.
• jdb command-line tool: Start it up with jdb -connect com.sun.jdi.SocketAttach:port=8000

In your Jenkins installation directory there is a jenkins.xml, where you can set various options. Add the parameter -Xmx with the size you want to the arguments-tag (or increase the size if its already there).

If you're using bootstrap 3 date time picker, try this:

There are a couple of issues with the above solutions. If you are using, for example, a UISplitViewController, the master view will always return true for

if(viewController.isViewLoaded && viewController.view.window) {
    //Always true for master view in split view controller
}

Instead, take this simple approach which seems to work well in most, if not all cases:

- (void)viewDidDisappear:(BOOL)animated {
    [super viewDidDisappear:animated];

    //We are now invisible
    self.visible = false;
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    //We are now visible
    self.visible = true;
}

The main function must be declared as a non-member function in the global namespace. This means that it cannot be a static or non-static member function of a class, nor can it be placed in a namespace (even the unnamed namespace).

The name main is not reserved in C++ except as a function in the global namespace. You are free to declare other entities named main, including among other things, classes, variables, enumerations, member functions, and non-member functions not in the global namespace.

You can declare a function named main as a member function or in a namespace, but such a function would not be the main function that designates where the program starts.

The main function cannot be declared as static or inline. It also cannot be overloaded; there can be only one function named main in the global namespace.

The main function cannot be used in your program: you are not allowed to call the main function from anywhere in your code, nor are you allowed to take its address.

The return type of main must be int. No other return type is allowed (this rule is in bold because it is very common to see incorrect programs that declare main with a return type of void; this is probably the most frequently violated rule concerning the main function).

There are two declarations of main that must be allowed:

int main()               // (1)
int main(int, char*[])   // (2)

In (1), there are no parameters.

In (2), there are two parameters and they are conventionally named argc and argv, respectively. argv is a pointer to an array of C strings representing the arguments to the program. argc is the number of arguments in the argv array.

Usually, argv[0] contains the name of the program, but this is not always the case. argv[argc] is guaranteed to be a null pointer.

Note that since an array type argument (like char*[]) is really just a pointer type argument in disguise, the following two are both valid ways to write (2) and they both mean exactly the same thing:

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

Some implementations may allow other types and numbers of parameters; you'd have to check the documentation of your implementation to see what it supports.

main() is expected to return zero to indicate success and non-zero to indicate failure. You are not required to explicitly write a return statement in main(): if you let main() return without an explicit return statement, it's the same as if you had written return 0;. The following two main() functions have the same behavior:

int main() { }
int main() { return 0; }

There are two macros, EXIT_SUCCESS and EXIT_FAILURE, defined in <cstdlib> that can also be returned from main() to indicate success and failure, respectively.

The value returned by main() is passed to the exit() function, which terminates the program.

Note that all of this applies only when compiling for a hosted environment (informally, an environment where you have a full standard library and there's an OS running your program). It is also possible to compile a C++ program for a freestanding environment (for example, some types of embedded systems), in which case startup and termination are wholly implementation-defined and a main() function may not even be required. If you're writing C++ for a modern desktop OS, though, you're compiling for a hosted environment.

If your merge was not too complicated another option would be to:

1. Move all the changes including the merge changes back to stash using "git stash"
2. Run the merge again and commit your changes (without the changes from the dropped stash)
3. Run a "git stash pop" which should ignore all the changes from your previous merge since the files are identical now.

After that you are left with only the changes from the stash you dropped too early.

Assign the enddate to some date variable because AddDays method returns new Datetime as the result..

Datetime somedate=endDate.AddDays(2);

I don't think jQuery supports the pseudo-selectors either, but it does provide a quick way to add events to one, many, or all of your similar controls and tags on a single page.

Best of all, you can chain the event binds and do it all in one line of script if you want. Much easier than manually editing all of the HTML to turn them on or off. Then again, since you can do the same in CSS I don't know that it buys you anything (other than learning jQuery).

There is no need to kill entire session. In Oracle 18c you could use ALTER SYSTEM CANCEL:

Cancelling a SQL Statement in a Session

You can cancel a SQL statement in a session using the ALTER SYSTEM CANCEL SQL statement.

Instead of terminating a session, you can cancel a high-load SQL statement in a session. When you cancel a DML statement, the statement is rolled back.

ALTER SYSTEM CANCEL SQL 'SID, SERIAL[, @INST_ID][, SQL_ID]';

If @INST_ID is not specified, the instance ID of the current session is used.

If SQL_ID is not specified, the currently running SQL statement in the specified session is terminated.

There are three tables: persons, schools and persons_schools, which connects persons to the schools they study in. A reference to the person with id=6 is absent in the table persons_schools. However the person with id=6 is presented in the result lef-joined grid.

How about making the <div id="mainWrapperDivWithBGImage"> as three divs, where the two outside divs hold the rounded corners images, and the middle div simply has a background-color to match the rounded corner images. Then you could simply place the other elements inside the middle div, or:

#outside_left{width:10px; float:left;}
#outside_right{width:10px; float:right;}
#middle{background-color:#color of rnd_crnrs_foo.gif; float:left;}

Then

HTML:

<div id="mainWrapperDivWithBGImage">
  <div id="outside_left><img src="rnd_crnrs_left.gif" /></div>
  <div id="middle">
    <div id="another_div"><img src="foo.gif" /></div>
  <div id="outside_right><img src="rnd_crnrs_right.gif" /></div>
</div>

You may have to do position:relative; and such.

var fileName = @"C:\ExcelFile.xlsx";
var connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + fileName + ";Extended Properties=\"Excel 12.0;IMEX=1;HDR=NO;TypeGuessRows=0;ImportMixedTypes=Text\""; ;
using (var conn = new OleDbConnection(connectionString))
{
    conn.Open();

    var sheets = conn.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables, new object[] { null, null, null, "TABLE" });
    using (var cmd = conn.CreateCommand())
    {
        cmd.CommandText = "SELECT * FROM [" + sheets.Rows[0]["TABLE_NAME"].ToString() + "] ";

        var adapter = new OleDbDataAdapter(cmd);
        var ds = new DataSet();
        adapter.Fill(ds);
    }
}

Here's a way of accomplishing this. It takes the param name and param value, and an optional 'clear'. If you supply clear=true, it will remove all other params and just leave the newly added one - in other cases, it will either replace the original with the new, or add it if it's not present in the querystring.

This is modified from the original top answer as that one broke if it replaced anything but the last value. This will work for any value, and preserve the existing order.

function setGetParameter(paramName, paramValue, clear)
{
clear = typeof clear !== 'undefined' ? clear : false;
var url = window.location.href;
var queryString = location.search.substring(1); 
var newQueryString = "";
if (clear)
{
    newQueryString = paramName + "=" + paramValue;
}
else if (url.indexOf(paramName + "=") >= 0)
{
    var decode = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); };
    var keyValues = queryString.split('&'); 
    for(var i in keyValues) { 
        var key = keyValues[i].split('=');
        if (key.length > 1) {
            if(newQueryString.length > 0) {newQueryString += "&";}
            if(decode(key[0]) == paramName)
            {
                newQueryString += key[0] + "=" + encodeURIComponent(paramValue);;
            }
            else
            {
                newQueryString += key[0] + "=" + key[1];
            }
        }
    } 
}
else
{
    if (url.indexOf("?") < 0)
        newQueryString = "?" + paramName + "=" + paramValue;
    else
        newQueryString = queryString + "&" + paramName + "=" + paramValue;
}
window.location.href = window.location.href.split('?')[0] + "?" + newQueryString;
}

Just add || true after the command where you want to ignore the error.

All I had to do was to install this

npm install @angular/animations@latest --save  

and then import

import { BrowserAnimationsModule } from '@angular/platform-browser/animations'; 

into your app.module.ts file.

You can use JQuery, select the item by id:

$("input#Password").attr("autocomplete","off");

Or select the item by type:

$("input[type='password']").attr("autocomplete","off");

Or also:

You can use pure Javascript:

document.getElementById('Password').autocomplete = 'off';

• Short version of (correct) tzaman answer will be (for fresh SVN)

  svn switch ^/branches/v1p2p3
  

• --relocate switch is deprecated anyway, when it needed you'll have to use svn relocate command

• Instead of creating snapshot-branch (ReadOnly) you can use tags (conventional RO labels for history)

On Windows, the caret character (^) must be escaped:

svn switch ^^/branches/v1p2p3

The termination of an array of characters with a null character is just a convention that is specifically for strings in C. You are dealing with something completely different -- an array of character pointers -- so it really has no relation to the convention for C strings. Sure, you could choose to terminate it with a null pointer; that perhaps could be your convention for arrays of pointers. There are other ways to do it. You can't ask people how it "should" work, because you're assuming some convention that isn't there.

Try using the duplicated function in combination with the negation operator "!".

Example:

wdups <- rep(1:5,5)
wodups <- wdups[which(!duplicated(wdups))]

Hope that helps.

After a wild goose chase with tons of Google searches and burteforce attempts, I think I found how to solve this problem.

Steps undertaken to solve the problem:

1. Uninstall R
2. Reinstall R

3. Install ggplot with the dependencies argument to install.packages set to TRUE

   install.packages("ggplot2",dependencies = TRUE)

4. The above step still does NOT include the Rcpp dependency so that has to be manually installed using the following command

   install.packages("Rcpp")

However, while the above command successfully downloads Rcpp, for some reason, it fails to explode the ZIP file and install it in my R's library folder citing the following error:

package ‘Rcpp’ successfully unpacked and MD5 sums checked Warning in install.packages : unable to move temporary installation ‘C:\Root_Prgs\Data_Science_SW\R\R-3.2.3\library\file27b8ef47b6d\Rcpp’ to ‘C:\Root_Prgs\Data_Science_SW\R\R-3.2.3\library\Rcpp’

The downloaded binary packages are in C:\Users\MY_USER_ID\AppData\Local\Temp\Rtmp25XQ0S\downloaded_packages

5. Note that the above output says "Warning" but actually, it is an indication of failure to install the Rcpp package successfully within the repository. I then used the Tools-->Install packages--> From ZIP file and pointed to the location of the "downloaded binary packages" in the message above -

C:\Users\MY_USER_ID\AppData\Local\Temp\Rtmp25XQ0S\downloaded_packages\Rcpp_0.12.3.zip

6. This led to successful installation of Rcpp in my R\R-3.2.3\library folder, thereby ensuring that Rcpp is now available when I attempt to load the library for ggplot2. I could not do this step in the past because my previous installation of R would throw error stating that Rcpp cannot be imported. However, the same command worked after I uninstalled and reinstalled R, which is ODD.

   install.packages("C:/Users/MY_USER_ID/AppData/Local/Temp/Rtmp25XQ0S/downloaded_packages/Rcpp_0.12.3.zip", repos = NULL, type = "win.binary") package ‘Rcpp’ successfully unpacked and MD5 sums checked`

7. I was finally able to load the ggplot2 library successfully.

   library(ggplot2)

Here it is how to use MockHttpServletRequest:

// given
MockHttpServletRequest request = new MockHttpServletRequest();
request.setServerName("www.example.com");
request.setRequestURI("/foo");
request.setQueryString("param1=value1&param");

// when
String url = request.getRequestURL() + '?' + request.getQueryString(); // assuming there is always queryString.

// then
assertThat(url, is("http://www.example.com:80/foo?param1=value1&param"));

Did you see this? If I haven't misunderstand that answer, you may try to create a new virtualenv on top of the old one. You just need to know which python is going to use your virtualenv (you will need to see your virtualenv version).

If your virtualenv is installed with the same python version of the old one and upgrading your virtualenv package is not an option, you may want to read this in order to install a virtualenv with the python version you want.

EDIT

I've tested this approach (the one that create a new virtualenv on top of the old one) and it worked fine for me. I think you may have some problems if you change from python 2.6 to 2.7 or 2.7 to 3.x but if you just upgrade inside the same version (staying at 2.7 as you want) you shouldn't have any problem, as all the packages are held in the same folders for both python versions (2.7.x and 2.7.y packages are inside your_env/lib/python2.7/).

If you change your virtualenv python version, you will need to install all your packages again for that version (or just link the packages you need into the new version packages folder, i.e: your_env/lib/python_newversion/site-packages)

Maybe whilst you added the userID column, there is a data for that certain table that it is established so it will have a default value of 0, try adding the column without the NOT NULL

Please remove all jar files of Http from 'libs' folder and add below dependencies in gradle file:

compile 'org.apache.httpcomponents:httpcore:4.4.3'

or

useLibrary 'org.apache.http.legacy'

I had a similar issue in windows 7 + ubuntu 12.04 as guest. I resolved by

• open 'network and sharing center' in windows
• right click 'nw-bridge' -> 'properties'
• Select "virtual box host only network" for the option "select adapters you want to use to connect computers on your local network"
• go to virtual box.. select the network type as NAT.

This saved my day. The simplest approach to get the path from URI.

  //kotlin
  myuri = data.data
  val realPath = myuri.path
  Log.d(TAG, "path: $realPath")

Returns path :

 path: /storage/emulated/0/Download/CutOFF - Escuro (Original Mix).mp3

To complete the other answers, in lodash 4 to ignore only undefined and null (And not properties like false) you can use a predicate in _.pickBy:

_.pickBy(obj, v !== null && v !== undefined)

Example below :

const obj = { a: undefined, b: 123, c: true, d: false, e: null};_x000D_
_x000D_
const filteredObject = _.pickBy(obj, v => v !== null && v !== undefined);_x000D_
_x000D_
console.log = (obj) => document.write(JSON.stringify(filteredObject, null, 2));_x000D_
console.log(filteredObject);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.10/lodash.js"></script>

The following will return true if the element is an input:

$("#elementId").is("input") 

or you can use the following to get the name of the tag:

$("#elementId").get(0).tagName

That doesn't work because distToPoint is inside your class, so you need to prefix it with the classname if you want to refer to it, like this: classname.distToPoint(self, p). You shouldn't do it like that, though. A better way to do it is to refer to the method directly through the class instance (which is the first argument of a class method), like so: self.distToPoint(p).

Seems you need to use JToggleButton :

JToggleButton tb = new JToggleButton("push me");
tb.addActionListener(new ActionListener() {

    @Override
    public void actionPerformed(ActionEvent e) {
        JToggleButton btn =  (JToggleButton) e.getSource();
        btn.setText(btn.isSelected() ? "pushed" : "push me");
    }
});

1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math

2: Yes: But you already know it:

`^`(x,y)
#[1] 1024

In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math.

Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply and sapply:

> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4

I used a few options mentioned above :

del self.left

or setting value to None using

self.left = None

It's important to know the differences and put a few exception handlers in place when you use set the value to None. If you're printing the value of the conditional statements using a template, say,

print("The value of the variable is {}".format(self.left))

you might see the value of the variable printing "The value of the variable is None". Thus, you'd have to put a few exception handlers there :

if self.left:
    #Then only print stuff

The above command will only print values if self.left is not None

The problem is that variables declared in one case are still visible in the subsequent cases unless an explicit { } block is used, but they will not be initialized because the initialization code belongs to another case.

In the following code, if foo equals 1, everything is ok, but if it equals 2, we'll accidentally use the i variable which does exist but probably contains garbage.

switch(foo) {
  case 1:
    int i = 42; // i exists all the way to the end of the switch
    dostuff(i);
    break;
  case 2:
    dostuff(i*2); // i is *also* in scope here, but is not initialized!
}

Wrapping the case in an explicit block solves the problem:

switch(foo) {
  case 1:
    {
        int i = 42; // i only exists within the { }
        dostuff(i);
        break;
    }
  case 2:
    dostuff(123); // Now you cannot use i accidentally
}

Edit

To further elaborate, switch statements are just a particularly fancy kind of a goto. Here's an analoguous piece of code exhibiting the same issue but using a goto instead of a switch:

int main() {
    if(rand() % 2) // Toss a coin
        goto end;

    int i = 42;

  end:
    // We either skipped the declaration of i or not,
    // but either way the variable i exists here, because
    // variable scopes are resolved at compile time.
    // Whether the *initialization* code was run, though,
    // depends on whether rand returned 0 or 1.
    std::cout << i;
}

This is the only thing that fit my unique constraints of wanting the folder to open as a Quizo Tab in any existing Explorer window.

$objShell = New-Object -ComObject "Shell.Application"
$objShell.Explore("path")

Try code below:

  console.log(event['target'].value)

it works for me :-)

To set parameters to your HttpPostRequest you can use BasicNameValuePair, something like this :

    HttpClient httpclient;
    HttpPost httpPost;
    ArrayList<NameValuePair> postParameters;
    httpclient = new DefaultHttpClient();
    httpPost = new HttpPost("your login link");


    postParameters = new ArrayList<NameValuePair>();
    postParameters.add(new BasicNameValuePair("param1", "param1_value"));
    postParameters.add(new BasicNameValuePair("param2", "param2_value"));

    httpPost.setEntity(new UrlEncodedFormEntity(postParameters, "UTF-8"));

    HttpResponse response = httpclient.execute(httpPost);

For me, my certificate is expired. I have created a new certificate.

Since String.format is only an extension function (see here) which internally calls java.lang.String.format you could write your own extension function using Java's DecimalFormat if you need more flexibility:

fun Double.format(fracDigits: Int): String {
    val df = DecimalFormat()
    df.setMaximumFractionDigits(fracDigits)
    return df.format(this)
}

println(3.14159.format(2)) // 3.14

If you use Ramda you can use its omit and clone functions to make a deep clone of your object and omit the unnecessary fields.

var object = {a: 1, b: 2, c: 3, y:25, z:26};
R.clone(R.omit(["z", "y"], object));

The collation is how SQL server decides on how to sort and compare text.

See MSDN.

Passing data to view is simple as passing object to method. Take a look at Controller.View Method

protected internal ViewResult View(
    Object model
)

Something like this

//controller

List<MyObject> list = new List<MyObject>();

return View(list);


//view

@model List<MyObject>

// and property Model is type of List<MyObject>

@foreach(var item in Model)
{
    <span>@item.Name</span>
}

Let's say I have code in the directory ~/local_dir/myNewApp, and I want to put it under 'https://svn.host/existing_path/myNewApp' (while being able to ignore some binaries, vendor libraries, etc.).

1. Create an empty folder in the repository svn mkdir https://svn.host/existing_path/myNewApp
2. Go to the parent directory of the project, cd ~/local_dir
3. Check out the empty directory over your local folder. Don't be afraid - the files you have locally will not be deleted. svn co https://svn.host/existing_path/myNewApp. If your folder has a different name locally than in the repository, you must specify it as an additional argument.
4. You can see that svn st will now show all your files as ?, which means that they are not currently under revision control
5. Perform svn add on files you want to add to the repository, and add others to svn:ignore. You may find some useful options with svn help add, for example --parents or --depth empty, when you want selectively add only some files/folders.
6. Commit with svn ci

Not really, no.

Java doesn't have pointers. If you really wanted you could try to emulate them by building around something like reflection, but it would have all of the complexity of pointers with none of the benefits.

Java doesn't have pointers because it doesn't need them. What kind of answers were you hoping for from this question, i.e. deep down did you hope you could use them for something or was this just curiousity?

A write-up of jme's suggestion, using pathlib, in Python 3.

from pathlib import Path

son = Path(r'/a/b/c/d')            
?
if parent in son.parents or parent==son:
    print(son.relative_to(parent)) # returns Path object equivalent to 'c/d'

This how to make input password that has hint which not converted to * !!.

On XML :

android:inputType="textPassword"
android:gravity="center"
android:ellipsize="start"
android:hint="Input Password !."

thanks to : mango and rjrjr for the insight :D.

Also, you can use spring annotation RequestMapping above controller class for receveing application/json;utf-8 in all responses

@Controller
@RequestMapping(produces = {"application/json; charset=UTF-8","*/*;charset=UTF-8"})
public class MyController{
 ...
}

Two ways

System.getProperty("user.dir");

or this

File currentDirFile = new File(".");
String helper = currentDirFile.getAbsolutePath();
String currentDir = helper.substring(0, helper.length() - currentDirFile.getCanonicalPath().length());//this line may need a try-catch block

The idea is to get the current folder with ".", and then fetch the absolute position to it and remove the filename from it, so from something like

/home/shark/eclipse/workspace/project/src/com/package/name/bin/Class.class

when you remove Class.class you'd get

/home/shark/eclipse/workspace/project/src/com/package/name/bin/

which is kinda what you want.

Video file example (HTML + Javascript):

function upload_check()
{
    var upl = document.getElementById("file_id");
    var max = document.getElementById("max_id").value;

    if(upl.files[0].size > max)
    {
       alert("File too big!");
       upl.value = "";
    }
};

<form action="some_script" method="post" enctype="multipart/form-data">
    <input id="max_id" type="hidden" name="MAX_FILE_SIZE" value="250000000" />
    <input onchange="upload_check()" id="file_id" type="file" name="file_name" accept="video/*" />

Taking Screen Shot in IOS Simulator is SO Simple.

When you Open Simulator In the Right Lift You See File.

Click On File And You See Option Save Screen Shot.

This Option Saves Your Screen Shot In Default Path Which is Desktop.

You can do it in the following way:

 myfxn <- function(var1,var2,var3){
      var1*var2*var3

    }

    lapply(1:3,myfxn,var2=2,var3=100)

and you will get the answer:

[[1]] [1] 200

[[2]] [1] 400

[[3]] [1] 600

I think the best way is to use currentTarget property instead of target property.

The currentTarget read-only property of the Event interface identifies the current target for the event, as the event traverses the DOM. It always refers to the element to which the event handler has been attached, as opposed to Event.target, which identifies the element on which the event occurred.

For example:

<a href="#"><span class="icon"></span> blah blah</a>

Javascript:

a.addEventListener('click', e => {
    e.currentTarget; // always returns "a" element
    e.target; // may return "a" or "span"
})

Because this question is still attracting a lot of users from google search(about Android timer) I would like to insert my two coins.

First of all, the Timer class will be deprecated in Java 9 (read the accepted answer).

The official suggested way is to use ScheduledThreadPoolExecutor which is more effective and features-rich that can additionally schedule commands to run after a given delay, or to execute periodically. Plus,it gives additional flexibility and capabilities of ThreadPoolExecutor.

Here is an example of using plain functionalities.

1. Create executor service:

   final ScheduledExecutorService SCHEDULER = Executors.newScheduledThreadPool(1);
   

2. Just schedule you runnable:

   final Future<?> future = SCHEDULER.schedule(Runnable task, long delay,TimeUnit unit);
   

3. You can now use future to cancel the task or check if it is done for example:

   future.isDone();
   

Hope you will find this useful for creating a tasks in Android.

Complete example:

ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);
Future<?> sampleFutureTimer = scheduler.schedule(new Runnable(), 120, TimeUnit.SECONDS);
if (sampleFutureTimer.isDone()){
    // Do something which will save world.
}

You can also define a scale transformation, with CSS like so:

.larger-icon {
 transform:scale(2);
}

You can also try react-native-extended-stylesheet that supports percentage for single-orientation apps:

import EStyleSheet from 'react-native-extended-stylesheet';

const styles = EStyleSheet.create({
  column: {
    width: '80%',
    height: '50%',
    marginLeft: '10%'
  }
});

<img src="w3schools.jpg" alt="W3Schools.com" width="104" height="142">

In above html tag we have different attributes like src, alt, width and height.

If you want to get the any attribute value from above html tag you have to pass attribute value in getAttribute() method

Syntax:

getAttribute(attributeValue)
getAttribute(src) you get w3schools.jpg
getAttribute(height) you get 142
getAttribute(width) you get 104 

Firstly, you probably want to add a return false; to the bottom of your Submit() method in JavaScript (so it stops the submit, since you're handling it in AJAX).

You're connecting to the complete event, not the success event - there's a significant difference and that's why your debugging results aren't as expected. Also, I've never made the signature methods match yours, and I've always provided a contentType and dataType. For example:

$.ajax({
        type: "POST",
        url: "Default.aspx/OnSubmit",
        data: dataValue,                
        contentType: 'application/json; charset=utf-8',
        dataType: 'json',
        error: function (XMLHttpRequest, textStatus, errorThrown) {
            alert("Request: " + XMLHttpRequest.toString() + "\n\nStatus: " + textStatus + "\n\nError: " + errorThrown);
        },
        success: function (result) {
            alert("We returned: " + result);
        }
    });

  The latest package as of now is WinSCP-5.17.10-Automation.zip;

• Extract the .zip archive along your script;

• Use a code like this (based on the official PowerShell upload example):

    # Load WinSCP .NET assembly
    Add-Type -Path "WinSCPnet.dll"
  
    # Setup session options
    $sessionOptions = New-Object WinSCP.SessionOptions -Property @{
        Protocol = [WinSCP.Protocol]::Sftp
        HostName = "example.com"
        UserName = "user"
        Password = "mypassword"
        SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
    }
  
    $session = New-Object WinSCP.Session
  
    try
    {
        # Connect
        $session.Open($sessionOptions)
  
        # Upload
        $session.PutFiles("C:\FileDump\export.txt", "/Outbox/").Check()
    }
    finally
    {
        # Disconnect, clean up
        $session.Dispose()
    }
  

You can have WinSCP generate the PowerShell script for the upload for you:

• Login to your server with WinSCP GUI;
• Navigate to the target directory in the remote file panel;
• Select the file for upload in the local file panel;
• Invoke the Upload command;
• On the Transfer options dialog, go to Transfer Settings > Generate Code;
• On the Generate transfer code dialog, select the .NET assembly code tab;
• Choose PowerShell language.

You will get a code like above with all session and transfer settings filled in.

I will use CXF also you can think of AXIS 2 .

The best way to do it may be using JAX RS Refer this example

Example:

wsimport -p stockquote http://stockquote.xyz/quote?wsdl

This will generate the Java artifacts and compile them by importing the http://stockquote.xyz/quote?wsdl.

You may need read this https://developer.android.com/guide/topics/resources/drawable-resource.html#Shape

and below there is a Note.

Note Every corner must (initially) be provided a corner radius greater than 1, or else no corners are rounded. If you want specific corners to not be rounded, a work-around is to use android:radius to set a default corner radius greater than 1, but then override each and every corner with the values you really want, providing zero ("0dp") where you don't want rounded corners.

A slight variation on glenn jackman's answer using paste: if the value for the -d delimiter option contains more than one character, paste cycles through the characters one by one, and combined with the -s options keeps doing that while processing the same input file.

This means that we can use whatever we want to have as the separator plus the escape sequence \n to merge two lines at a time.

Using a comma:

$ paste -s -d ',\n' infile
KEY 4048:1736 string,3
KEY 0:1772 string,1
KEY 4192:1349 string,1
KEY 7329:2407 string,2
KEY 0:1774 string,1

and the dollar sign:

$ paste -s -d '$\n' infile
KEY 4048:1736 string$3
KEY 0:1772 string$1
KEY 4192:1349 string$1
KEY 7329:2407 string$2
KEY 0:1774 string$1

What this cannot do is use a separator consisting of multiple characters.

As a bonus, if the paste is POSIX compliant, this won't modify the newline of the last line in the file, so for an input file with an odd number of lines like

KEY 4048:1736 string
3
KEY 0:1772 string

paste won't tack on the separation character on the last line:

$ paste -s -d ',\n' infile
KEY 4048:1736 string,3
KEY 0:1772 string

From this link http://www.svennerberg.com/2009/09/google-maps-api-3-infowindows/:

Teo: The easiest way to do this is to just have one instance of the InfoWindow object that you reuse over and over again. That way when you click a new marker the infoWindow is “moved” from where it’s currently at, to point at the new marker.

Use its setContent method to load it with the correct content.

Generally speaking, IN and JOIN are different queries that can yield different results.

SELECT  a.*
FROM    a
JOIN    b
ON      a.col = b.col

is not the same as

SELECT  a.*
FROM    a
WHERE   col IN
        (
        SELECT  col
        FROM    b
        )

, unless b.col is unique.

However, this is the synonym for the first query:

SELECT  a.*
FROM    a
JOIN    (
        SELECT  DISTINCT col
        FROM    b
        )
ON      b.col = a.col

If the joining column is UNIQUE and marked as such, both these queries yield the same plan in SQL Server.

If it's not, then IN is faster than JOIN on DISTINCT.

See this article in my blog for performance details:

• IN vs. JOIN vs. EXISTS

You can do the same with build.gradle

sonarqube {
properties {
    property "sonar.exclusions", "**/src/java/test/**/*.java"
  }
}

And if you want to exclude more files/directories then:

sonarqube {
properties {
    property "sonar.exclusions", "**/src/java/test/**/*.java, **/src/java/main/**/*.java"
  }
}

I work a lot with CSS panel and it's too slow in Safari Web Inspector. Apple knows about this problem and promise to fix this bug with freezes, except this thing web tools is much more powerful and convenient than firebug in mozilla, so waiting for fix.

A different approach using concat and drop_duplicates:

import sys
if sys.version_info[0] < 3:
    from StringIO import StringIO
else:
    from io import StringIO
import pandas as pd

DF1 = StringIO("""id   Name   score                    isEnrolled           Comment
111  Jack   2.17                     True                 "He was late to class"
112  Nick   1.11                     False                "Graduated"
113  Zoe    NaN                     True                  " "
""")
DF2 = StringIO("""id   Name   score                    isEnrolled           Comment
111  Jack   2.17                     True                 "He was late to class"
112  Nick   1.21                     False                "Graduated"
113  Zoe    NaN                     False                "On vacation" """)

df1 = pd.read_table(DF1, sep='\s+', index_col='id')
df2 = pd.read_table(DF2, sep='\s+', index_col='id')
#%%
dictionary = {1:df1,2:df2}
df=pd.concat(dictionary)
df.drop_duplicates(keep=False)

Output:

       Name  score isEnrolled      Comment
  id

  113   Zoe    NaN       True             
2 112  Nick   1.21      False    Graduated
  113   Zoe    NaN      False  On vacation

I know similar code that the OP posted in this question from generic parsers. From a performance perspective, you should use Unsafe.As<TFrom, TResult>(ref TFrom source), which can be found in the System.Runtime.CompilerServices.Unsafe NuGet package. It avoids boxing for value types in these scenarios. I also think that Unsafe.As results in less machine code produced by the JIT than casting twice (using (TResult) (object) actualString), but I haven't checked that out.

public TResult ParseSomething<TResult>(ParseContext context)
{
    if (typeof(TResult) == typeof(string))
    {
        var token = context.ParseNextToken();
        string parsedString = token.ParseToDotnetString();
        return Unsafe.As<string, TResult>(ref parsedString);
    }
    else if (typeof(TResult) == typeof(int))
    {
        var token = context.ParseNextToken();
        int parsedInt32 = token.ParseToDotnetInt32();
        // This will not box which might be critical to performance
        return Unsafe.As<int, TResult>(ref parsedInt32); 
    }
    // other cases omitted for brevity's sake
}

Unsafe.As will be replaced by the JIT with efficient machine code instructions, as you can see in the official CoreFX repo:

MDN has the following to say about string.concat():

It is strongly recommended to use the string concatenation operators (+, +=) instead of this method for perfomance reasons

Also see the link by @Bergi.

return StatusCode((int)HttpStatusCode.InternalServerError, e);

Should be used in non-ASP.NET contexts (see other answers for ASP.NET Core).

HttpStatusCode is an enumeration in System.Net.

brilliant example Jonathan Leffler, to make your code work on SLES, I needed to add an additional header to allow the pid_t object :)

#include <sys/types.h>

MAKE sure you have thymleaf on page already

//Use this in java
@Controller
@RequestMapping("/showingTymleafTextInJavaScript")
public String thankYou(Model model){
 model.addAttribute("showTextFromJavaController","dummy text");
 return "showingTymleafTextInJavaScript";
}


//thymleaf page  javascript page

console.log(showtext);

First off, that's not JSON. It's a JavaScript object literal. JSON is a string representation of data, that just so happens to very closely resemble JavaScript syntax.

Second, you have an object. They are unsorted. The order of the elements cannot be guaranteed. If you want guaranteed order, you need to use an array. This will require you to change your data structure.

One option might be to make your data look like this:

var json = [{
    "name": "user1",
    "id": 3
}, {
    "name": "user2",
    "id": 6
}, {
    "name": "user3",
    "id": 1
}];

Now you have an array of objects, and we can sort it.

json.sort(function(a, b){
    return a.id - b.id;
});

The resulting array will look like:

[{
    "name": "user3",
    "id" : 1
}, {
    "name": "user1",
    "id" : 3
}, {
    "name": "user2",
    "id" : 6
}];

you have to create an entry inside res/menu,override onCreateOptionsMenu and inflate it

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.yourentry, menu);
    return true;
}

an entry for the menu could be:

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <item
        android:id="@+id/action_cart"
        android:icon="@drawable/cart"
        android:orderInCategory="100"
        android:showAsAction="always"/> 
</menu>

As far as I am aware, simply opening the file in write mode without append mode will erase the contents of the file.

ofstream file("filename.txt"); // Without append
ofstream file("filename.txt", ios::app); // with append

The first one will place the position bit at the beginning erasing all contents while the second version will place the position bit at the end-of-file bit and write from there.

If you are using an external style sheet, the code could look something like this:

@font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
.junebug { font-family: Junebug; font-size: 4.2em; }

And should be saved in a separate .css file (eg styles.css). If your .css file is in a location separate from the page code, the actual font file should have the same path as the .css file, NOT the .html or .php web page file. Then the web page needs something like:

<link rel="stylesheet" href="css/styles.css">

in the <head> section of your html page. In this example, the font file should be located in the css folder along with the stylesheet. After this, simply add the class="junebug" inside any tag in your html to use Junebug font in that element.

If you're putting the css in the actual web page, add the style tag in the head of the html like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

And the actual element style can either be included in the above <style> and called per element by class or id, or you can just declare the style inline with the element. By element I mean <div>, <p>, <h1> or any other element within the html that needs to use the Junebug font. With both of these options, the font file (Junebug.ttf) should be located in the same path as the html page. Of these two options, the best practice would look like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
    .junebug { font-family: Junebug; font-size: 4.2em; }
</style>

and

<h1 class="junebug">This is Junebug</h1>

And the least acceptable way would be:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

and

<h1 style="font-family: Junebug;">This is Junebug</h1>

The reason it's not good to use inline styles is best practice dictates that styles should be kept all in one place so editing is practical. This is also the main reason that I recommend using the very first option of using external style sheets. I hope this helps.

<style>
a:hover {
    cursor:pointer;
}
</style>

I have just asked the Spring Cloud guys and thought I should share the info I have here.

bootstrap.yml is loaded before application.yml.

It is typically used for the following:

• when using Spring Cloud Config Server, you should specify spring.application.name and spring.cloud.config.server.git.uri inside bootstrap.yml
• some encryption/decryption information

Technically, bootstrap.yml is loaded by a parent Spring ApplicationContext. That parent ApplicationContext is loaded before the one that uses application.yml.

Add -m to the recommended answer above to prune empty directories.

You get the value of the textarea, use it :

$('.type').keyup(function() {
    var v = $('.type').val(); // you'd better use this.value here
    if (v.indexOf('> <')!=-1) {
       console.log('contains > <');        
    }
});

If you add this to your meta tags:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7" />

IE8 will render the page like IE7.

Consider that you work with RDBMS and have to select what to use - full table scans, or index access - but only one of them.
If you select full table scan - use hive. If index access - HBase.

Hands down the easiest way to parse a HTML table is to use pandas.read_html() - it accepts both URLs and HTML.

import pandas as pd
url = r'https://en.wikipedia.org/wiki/List_of_S%26P_500_companies'
tables = pd.read_html(url) # Returns list of all tables on page
sp500_table = tables[0] # Select table of interest

Only downside is that read_html() doesn't preserve hyperlinks.

Spring is a collection of best-practise API patterns, you can write up a shopping list of them as long as your arm. The way that the API is designed encourages you (but doesn't force you) to follow these patterns, and half the time you follow them without knowing you are doing so.

The below is the code that i used. It's working perfectly.

var geo = new google.maps.Geocoder;
geo.geocode({'address':address},function(results, status){
    if (status == google.maps.GeocoderStatus.OK) {              
        var myLatLng = results[0].geometry.location;

        // Add some code to work with myLatLng              

    } else {
        alert("Geocode was not successful for the following reason: " + status);
    }
});

Hope this will help.

C doesn't support exceptions. You can try compiling your C code as C++ with Visual Studio or G++ and see if it'll compile as-is. Most C applications will compile as C++ without major changes, and you can then use the try... catch syntax.

You want to make sure that appropriate files and directories are chmod-ed/permissions for those are appropriate. For all directories you want

find /opt/lampp/htdocs -type d -exec chmod 711 {} \;

And for all the images, JavaScript, CSS, HTML...well, you shouldn't execute them. So use

chmod 644 img/* js/* html/*

But for all the logic code (for instance PHP code), you should set permissions such that the user can't see that code:

chmod 600 file

For moment.js users, you can now use moment-timezone. Using it, your function would look something like this:

function toTimeZone(time, zone) {
    var format = 'YYYY/MM/DD HH:mm:ss ZZ';
    return moment(time, format).tz(zone).format(format);
}

Comment to Skelly's really helpful workaround: in Bootstrap-sass 3.3.6, utilities.scss, line 19: .pull-left has float:left !important. Since that, I recommend to use !important in his CSS as well:

.dropdown-submenu.pull-left {
    float:none !important;
}

Wrap the code in $(document).ready() method or $().

$(function(){

$('#content').click(function(e) {  
    alert(1);
});

});

Swift 2.0 solution:

You need to go into your Attribute Inspector and add a name for your cells Identifier:

Then you need to make your identifier match with your dequeue like this:

let cell2 = tableView.dequeueReusableCellWithIdentifier("ButtonCell", forIndexPath: indexPath) as! ButtonCell

Alternatively

If you're working with a nib you may need to register your class in your cellForRowAtIndexPath:

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {       

    tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "SwitchCell")

    // included for context            
    let cell = tableView.dequeueReusableCellWithIdentifier("SwitchCell", forIndexPath:indexPath) as! SwitchCell

    //... continue    
}

Apples's UITableView Class Reference says:

Prior to dequeueing any cells, call this method or the registerNib:forCellReuseIdentifier: method to tell the table view how to create new cells. If a cell of the specified type is not currently in a reuse queue, the table view uses the provided information to create a new cell object automatically.

If you previously registered a class or nib file with the same reuse identifier, the class you specify in the cellClass parameter replaces the old entry. You may specify nil for cellClass if you want to unregister the class from the specified reuse identifier.

Here's the code from Apples Swift 2.0 framework:

// Beginning in iOS 6, clients can register a nib or class for each cell.
// If all reuse identifiers are registered, use the newer -dequeueReusableCellWithIdentifier:forIndexPath: to guarantee that a cell instance is returned.
// Instances returned from the new dequeue method will also be properly sized when they are returned.

@available(iOS 5.0, *)
func registerNib(nib: UINib?, forCellReuseIdentifier identifier: String)

@available(iOS 6.0, *)
func registerClass(cellClass: AnyClass?, forCellReuseIdentifier identifier: String)

In rails 3 you can access the Rack::Mount::RouteSet object via the Rails.application.routes object, then call recognize on it directly

route, match, params = Rails.application.routes.set.recognize(controller.request)

that gets the first (best) match, the following block form loops over the matching routes:

Rails.application.routes.set.recognize(controller.request) do |r, m, p|
  ... do something here ...
end

once you have the route, you can get the route name via route.name. If you need to get the route name for a particular URL, not the current request path, then you'll need to mock up a fake request object to pass down to rack, check out ActionController::Routing::Routes.recognize_path to see how they're doing it.

with your VARCHAR, you may also need to specify the length, or its usually good to

What about grabbing the text, making a sting of it, then putting it into the query witrh

String TableName = "ComplicatedTableNameHere";  
EditText editText1 = (EditText) findViewById(R.id.EditTextIDhere); 
String editTextString1 = editText1.getText().toString();  

BROKEN DOWN

String TableName = "ComplicatedTableNameHere";            
    //sets the table name as a string so you can refer to TableName instead of writing out your table name everytime

EditText editText1 = (EditText) findViewById(R.id.EditTextIDhere); 
    //gets the text from your edit text fieldfield 
    //editText1 = your edit text name
    //EditTextIDhere = the id of your text field

String editTextString1 = editText1.getText().toString();  
    //sets the edit text as a string
    //editText1 is the name of the Edit text from the (EditText) we defined above
    //editTextString1 = the string name you will refer to in future

then use

       /* Insert data to a Table*/
       myDB.execSQL("INSERT INTO "
         + TableName
         + " (Column_Name, Column_Name2, Column_Name3, Column_Name4)"
         + " VALUES ( "+EditTextString1+", 'Column_Value2','Column_Value3','Column_Value4');");

Hope this helps some what...

NOTE each string is within

'"+stringname+"'

its the 'and' that enable the multi line element of the srting, without it you just get the first line, not even sure if you get the whole line, it may just be the first word

Slightly upgraded answer from @David George:

public static double distance(double lat1, double lat2, double lon1,
                              double lon2, double el1, double el2) {

    final int R = 6371; // Radius of the earth

    double latDistance = Math.toRadians(lat2 - lat1);
    double lonDistance = Math.toRadians(lon2 - lon1);
    double a = Math.sin(latDistance / 2) * Math.sin(latDistance / 2)
            + Math.cos(Math.toRadians(lat1)) * Math.cos(Math.toRadians(lat2))
            * Math.sin(lonDistance / 2) * Math.sin(lonDistance / 2);
    double c = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1 - a));
    double distance = R * c * 1000; // convert to meters

    double height = el1 - el2;

    distance = Math.pow(distance, 2) + Math.pow(height, 2);

    return Math.sqrt(distance);
}

public static double distanceBetweenLocations(Location l1, Location l2) {
    if(l1.hasAltitude() && l2.hasAltitude()) {
        return distance(l1.getLatitude(), l2.getLatitude(), l1.getLongitude(), l2.getLongitude(), l1.getAltitude(), l2.getAltitude());
    }
    return l1.distanceTo(l2);
}

distance function is the same, but I've created I small wrapper function, which takes 2 Location objects. Thanks to this, I only use distance function if both of locations actually have altitude, because sometimes they don't. And it can lead to strange results (if location doesn't know its altitude 0 will be returned). In this case, I fall back to classic distanceTo function.

Unless I grossly misunderstood your question, move overflow-x:scroll from .search-table to .search-table-outter.

http://jsfiddle.net/ZXnqM/4/

.search-table-outter {border:2px solid red; overflow-x:scroll;}
.search-table{table-layout: fixed; margin:40px auto 0px auto;   }

As far as I know you can't give scrollbars to tables themselves.

How to make first option of <select > selected with jQuery?

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

To add the the other answers, the POxx terms all appear to stem from POTS (Plain old telephone services).

The POX, used to define simple (plain old) XML, rather than the complex multi-layered stuff associated with REST, SOAP etc, was a useful, and vaguely amusing, term. PO(insert language of choice)O terms have rather worn the joke thin.

In Java, you can have just one public static void main(String[] args) per class. Which mean, if your program has multiple classes, each class can have public static void main(String[] args). See JLS for details.

Before everyone jumps to HOLDLOCK-s out of fear from these nafarious users running your sprocs directly :-) let me point out that you have to guarantee uniqueness of new PK-s by design (identity keys, sequence generators in Oracle, unique indexes for external ID-s, queries covered by indexes). That's the alpha and omega of the issue. If you don't have that, no HOLDLOCK-s of the universe are going to save you and if you do have that then you don't need anything beyond UPDLOCK on the first select (or to use update first).

Sprocs normally run under very controlled conditions and with the assumption of a trusted caller (mid tier). Meaning that if a simple upsert pattern (update+insert or merge) ever sees duplicate PK that means a bug in your mid-tier or table design and it's good that SQL will yell a fault in such case and reject the record. Placing a HOLDLOCK in this case equals eating exceptions and taking in potentially faulty data, besides reducing your perf.

Having said that, Using MERGE, or UPDATE then INSERT is easier on your server and less error prone since you don't have to remember to add (UPDLOCK) to first select. Also, if you are doing inserts/updates in small batches you need to know your data in order to decide whether a transaction is appropriate or not. It it's just a collection of unrelated records then additional "enveloping" transaction will be detrimental.

$total_ratings is an array.

This simple mechanism you can use for detecting finishing of a thread without blocking in join method.

std::thread thread([&thread]() {
    sleep(3);
    thread.detach();
});

while(thread.joinable())
    sleep(1);

Range("A1").value = Environ("Username")

This is better than Application.Username, which doesn't always supply the Windows username. Thanks to Kyle for pointing this out.

• Application Username is the name of the User set in Excel > Tools > Options
• Environ("Username") is the name you registered for Windows; see Control Panel >System

My solution is a bit funny.I never thought that would it be as easy as save as with UTF-8 codec.I'm using notepad++(v5.6.8).I didn't notice that I saved it with ANSI codec initially. I'm using separate file to place all localized dictionary. I found my solution under 'Encoding' tab from my Notepad++.I select 'Encoding in UTF-8 without BOM' and save it. It works brilliantly.

 protected void Application_Start(object sender, EventArgs e)
 {
     string path = Server.MapPath("/");
     //or 
     string path2 = Server.MapPath("~");
     //depends on your application needs

 }

Just use

int listCount = data.size();

That tells you how many lists there are (assuming none are null). If you want to find out how many strings there are, you'll need to iterate:

int total = 0;
for (List<String> sublist : data) {
    // TODO: Null checking
    total += sublist.size();
}
// total is now the total number of strings

Swift 2 and below

let date = NSDate()
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.stringFromDate(date)
println(dateString)

And in Swift 3 and higher this would now be written as:

let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "MM-dd-yyyy"
var dateString = dateFormatter.string(from: date)

when your document is ready that doesn't mean that your iframe is ready too,
so you should listen to the iframe load event then access your contents:

$(function() {
    $("#my-iframe").bind("load",function(){
        $(this).contents().find("[tokenid=" + token + "]").html();
    });
});

Needed this answer myself and from the link provided by David Moye, decided on this and thought it might be of use to others with the same question:

CREATE PROCEDURE ...
AS
BEGIN
  BEGIN TRANSACTION

  -- lock table "a" till end of transaction
  SELECT ...
  FROM a
  WITH (TABLOCK, HOLDLOCK)
  WHERE ...

  -- do some other stuff (including inserting/updating table "a")



  -- release lock
  COMMIT TRANSACTION
END

No problem if all the arrays you are about to use in this scenario are small like in your example.

If you will use this for large blobs (e.g. storing large binary files many Mbs or even Gbs in size into a VARBINARY) then you'd probably be much better off using specific support in SQL Server for reading/writing subsections of such large blobs. Things like READTEXT and UPDATETEXT, or in current versions of SQL Server SUBSTRING.

For more information and examples see either my 2006 article in .NET Magazine ("BLOB + Stream = BlobStream", in Dutch, with complete source code), or an English translation and generalization of this on CodeProject by Peter de Jonghe. Both of these are linked from my weblog.

Why would UPDLOCK block selects? The Lock Compatibility Matrix clearly shows N for the S/U and U/S contention, as in No Conflict.

As for the HOLDLOCK hint the documentation states:

HOLDLOCK: Is equivalent to SERIALIZABLE. For more information, see SERIALIZABLE later in this topic.

...

SERIALIZABLE: ... The scan is performed with the same semantics as a transaction running at the SERIALIZABLE isolation level...

and the Transaction Isolation Level topic explains what SERIALIZABLE means:

No other transactions can modify data that has been read by the current transaction until the current transaction completes.

Other transactions cannot insert new rows with key values that would fall in the range of keys read by any statements in the current transaction until the current transaction completes.

Therefore the behavior you see is perfectly explained by the product documentation:

• UPDLOCK does not block concurrent SELECT nor INSERT, but blocks any UPDATE or DELETE of the rows selected by T1
• HOLDLOCK means SERALIZABLE and therefore allows SELECTS, but blocks UPDATE and DELETES of the rows selected by T1, as well as any INSERT in the range selected by T1 (which is the entire table, therefore any insert).
• (UPDLOCK, HOLDLOCK): your experiment does not show what would block in addition to the case above, namely another transaction with UPDLOCK in T2:
  SELECT * FROM dbo.Test WITH (UPDLOCK) WHERE ...
• TABLOCKX no need for explanations

The real question is what are you trying to achieve? Playing with lock hints w/o an absolute complete 110% understanding of the locking semantics is begging for trouble...

After OP edit:

I would like to select rows from a table and prevent the data in that table from being modified while I am processing it.

The you should use one of the higher transaction isolation levels. REPEATABLE READ will prevent the data you read from being modified. SERIALIZABLE will prevent the data you read from being modified and new data from being inserted. Using transaction isolation levels is the right approach, as opposed to using query hints. Kendra Little has a nice poster exlaining the isolation levels.

It seems that you're mainly hesitating whether to use a relational model or not.

As it stands, your example would fit a relational model reasonably well, but the problem may come of course when you need to make this model evolve.

If you only have one (or a few pre-determined) levels of attributes for your main entity (user), you could still use an Entity Attribute Value (EAV) model in a relational database. (This also has its pros and cons.)

If you anticipate that you'll get less structured values that you'll want to search using your application, MySQL might not be the best choice here.

If you were using PostgreSQL, you could potentially get the best of both worlds. (This really depends on the actual structure of the data here... MySQL isn't necessarily the wrong choice either, and the NoSQL options can be of interest, I'm just suggesting alternatives.)

Indeed, PostgreSQL can build index on (immutable) functions (which MySQL can't as far as I know) and in recent versions, you could use PLV8 on the JSON data directly to build indexes on specific JSON elements of interest, which would improve the speed of your queries when searching for that data.

EDIT:

Since there won't be too many columns on which I need to perform search, is it wise to use both the models? Key-per-column for the data I need to search and JSON for others (in the same MySQL database)?

Mixing the two models isn't necessarily wrong (assuming the extra space is negligible), but it may cause problems if you don't make sure the two data sets are kept in sync: your application must never change one without also updating the other.

A good way to achieve this would be to have a trigger perform the automatic update, by running a stored procedure within the database server whenever an update or insert is made. As far as I'm aware, the MySQL stored procedure language probably lack support for any sort of JSON processing. Again PostgreSQL with PLV8 support (and possibly other RDBMS with more flexible stored procedure languages) should be more useful (updating your relational column automatically using a trigger is quite similar to updating an index in the same way).

Here Response.Write():to display only string and you can not display any other data type values like int,date,etc.Conversion(from one data type to another) is not allowed. whereas Response .Output .Write(): you can display any type of data like int, date ,string etc.,by giving index values.

Here is example:

protected void Button1_Click(object sender, EventArgs e)
    {
       Response.Write ("hi good morning!"+"is it right?");//only strings are allowed        
       Response.Write("Scott is {0} at {1:d}", "cool", DateTime.Now);//this will give error(conversion is not allowed)
       Response.Output.Write("\nhi goood morning!");//works fine
       Response.Output.Write("Jai is {0} on {1:d}", "cool", DateTime.Now);//here the current date will be converted into string and displayed
    }

Or with Prototype:

Event.observe(this, 'load', function() { new Ajax.Request(... ) );

Or better, define the function elsewhere rather than inline, then:

Event.observe(this, 'load', functionName );

You don't have to use jQuery or Prototype specifically, but I hope you're using some kind of library. Either library is going to handle the event handling in a more consistent manner than onload, and of course is going to make it much easier to process the Ajax call. If you must use the body onload attribute, then you should just be able to call the same function as referenced in these examples (onload="javascript:functionName();").

However, if your database update doesn't depend on the rendering on the page, why wait until it's fully loaded? You could just include a call to the Ajax-calling function at the end of the JavaScript on the page, which should give nearly the same effect.

Google Map V2

The following solution works for Android Marshmallow 6 (API 23, API 24, API 25, API 26, API 27, API 28). It also works in Xamarin.

LatLngBounds.Builder builder = new LatLngBounds.Builder();

//the include method will calculate the min and max bound.
builder.include(marker1.getPosition());
builder.include(marker2.getPosition());
builder.include(marker3.getPosition());
builder.include(marker4.getPosition());

LatLngBounds bounds = builder.build();

int width = getResources().getDisplayMetrics().widthPixels;
int height = getResources().getDisplayMetrics().heightPixels;
int padding = (int) (width * 0.10); // offset from edges of the map 10% of screen

CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, width, height, padding);

mMap.animateCamera(cu);

When a dictionary is enumerated, it will yield KeyValuePair<TKey,TValue> objects... so you just need to specify "Value" and "Key" for DataTextField and DataValueField respectively, to select the Value/Key properties.

Thanks to Joe's comment, I reread the question to get these the right way round. Normally I'd expect the "key" in the dictionary to be the text that's displayed, and the "value" to be the value fetched. Your sample code uses them the other way round though. Unless you really need them to be this way, you might want to consider writing your code as:

list.Add(cul.DisplayName, cod);

(And then changing the binding to use "Key" for DataTextField and "Value" for DataValueField, of course.)

In fact, I'd suggest that as it seems you really do want a list rather than a dictionary, you might want to reconsider using a dictionary in the first place. You could just use a List<KeyValuePair<string, string>>:

string[] languageCodsList = service.LanguagesAvailable();
var list = new List<KeyValuePair<string, string>>();

foreach (string cod in languageCodsList)
{
    CultureInfo cul = new CultureInfo(cod);
    list.Add(new KeyValuePair<string, string>(cul.DisplayName, cod));
}

Alternatively, use a list of plain CultureInfo values. LINQ makes this really easy:

var cultures = service.LanguagesAvailable()
                      .Select(language => new CultureInfo(language));
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

If you're not using LINQ, you can still use a normal foreach loop:

List<CultureInfo> cultures = new List<CultureInfo>();
foreach (string cod in service.LanguagesAvailable())
{
    cultures.Add(new CultureInfo(cod));
}
languageList.DataTextField = "DisplayName";
languageList.DataValueField = "Name";
languageList.DataSource = cultures;
languageList.DataBind();

std::sort(str.begin(), str.end());

In my case the key was:

Based on the documentation:

androidx is new package structure to make it clearer which packages are bundled with the Android operating system, and which are packaged with your app's APK. Going forward, the android.* package hierarchy will be reserved for Android packages that ship with the operating system; other packages will be issued in the new androidx.* package hierarchy.

The re-designed package structure is to encourage smaller and more focused libraries. You find details regarding the artifact mappings here.

There are support libraries (containing component and packages for backward compatibility) named "v7" when the minimal SDK level supported is 14, the new naming makes it clear to understand the division between APIs bundled with platform and the libraries for app developers which are used on different versions of Android. You can refer to official announcement for more details.

Just do the same thing agin but then for TableC

SELECT *
FROM dbo.tableA A 
INNER JOIN dbo.TableB B ON A.common = B.common
INNER JOIN dbo.TableC C ON A.common = C.common

strong: assigns the incoming value to it, it will retain the incoming value and release the existing value of the instance variable

weak: will assign the incoming value to it without retaining it.

So the basic difference is the retaining of the new variable. Generaly you want to retain it but there are situations where you don't want to have it otherwise you will get a retain cycle and can not free the memory the objects. Eg. obj1 retains obj2 and obj2 retains obj1. To solve this kind of situation you use weak references.

You can check the local and global value of it with:

SELECT @@SQL_MODE, @@GLOBAL.SQL_MODE;

alternatively you can retrieve DOM properties with .prop

here is sample code for select box

if( ctrl.prop('type') == 'select-one' ) { // for single select }

if( ctrl.prop('type') == 'select-multiple' ) { // for multi select }

for textbox

  if( ctrl.prop('type') == 'text' ) { // for text box }

Within the package there is a class called JwtSecurityTokenHandler which derives from System.IdentityModel.Tokens.SecurityTokenHandler. In WIF this is the core class for deserialising and serialising security tokens.

The class has a ReadToken(String) method that will take your base64 encoded JWT string and returns a SecurityToken which represents the JWT.

The SecurityTokenHandler also has a ValidateToken(SecurityToken) method which takes your SecurityToken and creates a ReadOnlyCollection<ClaimsIdentity>. Usually for JWT, this will contain a single ClaimsIdentity object that has a set of claims representing the properties of the original JWT.

JwtSecurityTokenHandler defines some additional overloads for ValidateToken, in particular, it has a ClaimsPrincipal ValidateToken(JwtSecurityToken, TokenValidationParameters) overload. The TokenValidationParameters argument allows you to specify the token signing certificate (as a list of X509SecurityTokens). It also has an overload that takes the JWT as a string rather than a SecurityToken.

The code to do this is rather complicated, but can be found in the Global.asax.cx code (TokenValidationHandler class) in the developer sample called "ADAL - Native App to REST service - Authentication with ACS via Browser Dialog", located at

http://code.msdn.microsoft.com/AAL-Native-App-to-REST-de57f2cc

Alternatively, the JwtSecurityToken class has additional methods that are not on the base SecurityToken class, such as a Claims property that gets the contained claims without going via the ClaimsIdentity collection. It also has a Payload property that returns a JwtPayload object that lets you get at the raw JSON of the token. It depends on your scenario which approach it most appropriate.

The general (i.e. non JWT specific) documentation for the SecurityTokenHandler class is at

http://msdn.microsoft.com/en-us/library/system.identitymodel.tokens.securitytokenhandler.aspx

Depending on your application, you can configure the JWT handler into the WIF pipeline exactly like any other handler.

There are 3 samples of it in use in different types of application at

http://code.msdn.microsoft.com/site/search?f%5B0%5D.Type=SearchText&f%5B0%5D.Value=aal&f%5B1%5D.Type=User&f%5B1%5D.Value=Azure%20AD%20Developer%20Experience%20Team&f%5B1%5D.Text=Azure%20AD%20Developer%20Experience%20Team

Probably, one will suite your needs or at least be adaptable to them.

Paul Irish's approach to IE specific CSS is the most elegant I've seen. It uses conditional statements to add classes to the HTML element, which can then be used to apply appropriate IE version specific CSS without resorting to hacks. The CSS validates, and it will continue to work down the line for future browser versions.

The full details of the approach can be seen on his site.

This doesn't cover browser specific hacks for Mozilla and Chrome... but I don't really find I need those anyway.

By the sound of it you have a misconfigured device. If you do it will never start and never show anything in Logcat.

I'd recommend creating a new device using one of the default "Device Definitions" available in the AVD Manager. It's as easy as highlighting the device type you want in the "Device Definitions" tab and clicking the "Create AVD..." button, then filling out a few details. I'd start by adjusting "Internal Storage" to around 8GB and (maybe) an "SD Card" of 2GB while leaving everything else the same. Try starting the device and if you see "Android" pop up onscreen you're running. The first boot usually takes awhile so just hang on and watch Logcat for any issues (the "DDMS" perspective helps here).

If you still see a black screen with a default device definition you've got problems elsewhere that are causing the device to fail. Digging through logs may be your only chance if that's the case. You can always try re-downloading the ADT and re-installing the SDKs if nothing else works.

The goal here is to get you up and running with a (very) basic device, so don't shoot for uber impressive specs at this point, just shoot for trying to make it run. Once that happens try adjusting the settings one-by-one until you have it spec'd out the way you like. Just keep in mind that the emulator has its limitations and its no substitute for a real device (Although it works most of the time ;)
