My which pip shows the following path:

$ which pip
/home/kmario23/anaconda3/bin/pip

So, whatever package I install using pip install <package-name> will have to be reflected in the list of packages when the list is exported using:

$ conda list --export > conda_list.txt

But, I don't. So, instead I used the following command as suggested by several others:

# get environment name by
$ conda-env list

# get list of all installed packages by (conda, pip, etc.,)
$ conda-env export -n <my-environment-name> > all_packages.yml
# if you haven't created any specific env, then just use 'root'

Now, I can see all the packages in my all-packages.yml file.

I believe you can pass in event into the function inline which will be the event object for the raised event in W3C compliant browsers (i.e. older versions of IE will still require detection inside of your event handler function to look at window.event).

A quick example.

function sayHi(e) {_x000D_
   e.preventDefault();_x000D_
   alert("hi");_x000D_
}

<a href="http://google.co.uk" onclick="sayHi(event);">Click to say Hi</a>

1. Run it as is and notice that the link does no redirect to Google after the alert.
2. Then, change the event passed into the onclick handler to something else like e, click run, then notice that the redirection does take place after the alert (the result pane goes white, demonstrating a redirect).

in jQuery you might target the Parent directly.

THIS IS USEFUL IF YOU DO NOT KNOW EXACTLY HOW MANY CHILDREN WILL BE ADDED DYNAMICALLY or IF YOU JUST CAN'T FIGURE OUT THEIR NUMBER.

var tWidth=0;

$('.children').each(function(i,e){
tWidth += $(e).width();

///Example: If the Children have a padding-left of 10px;..
//You could do instead:
tWidth += ($(e).width()+10);

})
$('#parent').css('width',tWidth);

This will let the parent grow horizontally as the children are beng added.

NOTE: This assumes that the '.children' have a width and Height Set

Hope that Helps.

If you want to post an array you must use another notation:

foreach ($postvalue as $value){
<input type="hidden" name="result[]" value="$value.">
}

in this way you have three input fields with the name result[] and when posted $_POST['result'] will be an array

(I'm always wondering why std::map does not include a member function for us to do so.)

Because it can't do it any better than you can do it. If a method's implementation will be no superior to a free function's implementation then in general you should not write a method; you should write a free function.

It's also not immediately clear why it's useful anyway.

The jQuery way

In jQuery, you can use $('#id').children().length > 0 to test if an element has children.

Demo

var test1 = $('#test');_x000D_
var test2 = $('#test2');_x000D_
_x000D_
if(test1.children().length > 0) {_x000D_
    test1.addClass('success');_x000D_
} else {_x000D_
    test1.addClass('failure');_x000D_
}_x000D_
_x000D_
if(test2.children().length > 0) {_x000D_
    test2.addClass('success');_x000D_
} else {_x000D_
    test2.addClass('failure');_x000D_
}

.success {_x000D_
    background: #9f9;_x000D_
}_x000D_
_x000D_
.failure {_x000D_
    background: #f99;_x000D_
}

<script src="https://code.jquery.com/jquery-1.12.2.min.js"></script>_x000D_
<div id="test">_x000D_
   <span>Children</span>_x000D_
</div>_x000D_
<div id="test2">_x000D_
   No children_x000D_
</div>

The vanilla JS way

If you don't want to use jQuery, you can use document.getElementById('id').children.length > 0 to test if an element has children.

Demo

var test1 = document.getElementById('test');_x000D_
var test2 = document.getElementById('test2');_x000D_
_x000D_
if(test1.children.length > 0) {_x000D_
    test1.classList.add('success');_x000D_
} else {_x000D_
    test1.classList.add('failure');_x000D_
}_x000D_
_x000D_
if(test2.children.length > 0) {_x000D_
    test2.classList.add('success');_x000D_
} else {_x000D_
    test2.classList.add('failure');_x000D_
}

.success {_x000D_
    background: #9f9;_x000D_
}_x000D_
_x000D_
.failure {_x000D_
    background: #f99;_x000D_
}

<div id="test">_x000D_
   <span>Children</span>_x000D_
</div>_x000D_
<div id="test2">_x000D_
   No children_x000D_
</div>

when i used FQL I found the problem (but it is still problem) the documentation says that the number shown is the sum of:

• number of likes of this URL
• number of shares of this URL (this includes copy/pasting a link back to Facebook)
• number of likes and comments on stories on Facebook about this URL
• number of inbox messages containing this URL as an attachment.

but on my website the shown number is sum of these 4 counts + number of shares (again)

Create controller go to cmd and the type php artisan make:controller auth\LoginController

from within the vscode terminal,

git remote set-url origin https://<your github username>:<your password>@github.com/<your github username>/<your github repository name>.git

for the quickest, but not so encouraged way.

Make sure that you place the @JsonIgnoreProperties(ignoreUnknown = true) annotation to the parent POJO class which you want to populate as a result of parsing the JSON response and not the class where the conversion from JSON to Java Object is taking place.

Old post but as you said "why is it not using the correct certificate" I would like to offer an way to find out which SSL certificate is used for SMTP (see here) which required openssl:

openssl s_client -connect exchange01.int.contoso.com:25 -starttls smtp

This will outline the used SSL certificate for the SMTP service. Based on what you see here you can replace the wrong certificate (like you already did) with a correct one (or trust the certificate manually).

Somehow I got it to work by using margin-right, and setting it to move from right to left. http://jsfiddle.net/gXdMc/

Don't know why for this case, margin-right 100% doesn't go off the screen. :D (tested on chrome 18)

EDIT: now left to right works too http://jsfiddle.net/6LhvL/

Late, but can be done by using Object.keys like,

var a={key1:'value1',key2:'value2',key3:'value3',key4:'value4'},_x000D_
  ulkeys=document.getElementById('object-keys'),str='';_x000D_
var keys = Object.keys(a);_x000D_
for(i=0,l=keys.length;i<l;i++){_x000D_
   str+= '<li>'+keys[i]+' : '+a[keys[i]]+'</li>';_x000D_
}_x000D_
ulkeys.innerHTML=str;

<ul id="object-keys"></ul>

First, make sure that the source page and the target page are both served through the file URI scheme. You can't force an http page to open a file page (but it works the other way around).

Next, your script that calls window.open() should be invoked by a user-initiated event, such as clicks, keypresses and the like. Simply calling window.open() won't work.

You can test this right here in this question page. Run these in Chrome's JavaScript console:

// Does nothing
window.open('http://google.com');

// Click anywhere within this page and the new window opens
$(document.body).unbind('click').click(function() { window.open('http://google.com'); });

// This will open a new window, but it would be blank
$(document.body).unbind('click').click(function() { window.open('file:///path/to/a/local/html/file.html'); });

You can also test if this works with a local file. Here's a sample HTML file that simply loads jQuery:

<html>
    <head>
        <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.0/jquery.min.js"></script>
    </head>
    <body>
        <h5>Feel the presha</h5>
        <h3>Come play my game, I'll test ya</h3>
        <h1>Psycho- somatic- addict- insane!</h1>
    </body>
</html>

Then open Chrome's JavaScript console and run the statements above. The 3rd one will now work.

Alternatively you could read you csv with header=None and then add it with df.columns:

Cov = pd.read_csv("path/to/file.txt", sep='\t', header=None)
Cov.columns = ["Sequence", "Start", "End", "Coverage"]

Using Date Formatter -Swift 3.0

//Date
let dateFormatter = DateFormatter()
dateFormatter.dateStyle = .medium
let dateString = "Current date is: \(dateFormatter.string(from: Date() as Date))"
labelfordate.text = String(dateString)


//Time    
let timeFormatter = DateFormatter()
timeFormatter.timeStyle = .medium
let timeString = "Current time is: \(timeFormatter.string(from: Date() as Date))"
labelfortime.text = String(timeString)

Update Date and Time Every Seconds

override func viewDidLoad() {
super.viewDidLoad()

timer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(DateAndTime.action), userInfo: nil, repeats: true)

       }

func action()
    {
    //Date
    let dateFormatter = DateFormatter()
    dateFormatter.dateStyle = .medium
    let dateString = "Current date is: \(dateFormatter.string(from: Date() as Date))"
    labelfordate.text = String(dateString)


    //Time
    let timeFormatter = DateFormatter()
    timeFormatter.timeStyle = .medium
    let timeString = "Current time is: \(timeFormatter.string(from: Date() as Date))"
    labelfortime.text = String(timeString)

    }

Note: DateAndTime in the Timer code is the Class name.

If you are using RC5 then import this:

import { CommonModule } from '@angular/common';  
import { BrowserModule } from '@angular/platform-browser';

and be sure to import CommonModule from the module that is providing your component.

 @NgModule({
    imports: [CommonModule],
    declarations: [MyComponent]
  ...
})
class MyComponentModule {}

I suggest that you start from a question in StackOverflow that discusses the advantages of stateless programming. This is more in the context of functional programming, but what you will read also applies in other programming paradigms.

Stateless programming is related to the mathematical notion of a function, which when called with the same arguments, always return the same results. This is a key concept of the functional programming paradigm and I expect that you will be able to find many relevant articles in that area.

Another area that you could research in order to gain more understanding is RESTful web services. These are by design "stateless", in contrast to other web technologies that try to somehow keep state. (In fact what you say that ASP.NET is stateless isn't correct - ASP.NET tries hard to keep state using ViewState and are definitely to be characterized as stateful. ASP.NET MVC on the other hand is a stateless technology). There are many places that discuss "statelessness" of RESTful web services (like this blog spot), but you could again start from an SO question.

You need to use the enumerate function: python docs

for place, item in enumerate(list):
    if "foo" in item:
        item = replace_all(item, replaceDictionary)
        list[place] = item
        print item

Also, it's a bad idea to use the word list as a variable, due to it being a reserved word in python.

Since you had problems with enumerate, an alternative from the itertools library:

for place, item in itertools.zip(itertools.count(0), list):
    if "foo" in item:
        item = replace_all(item, replaceDictionary)
        list[place] = item
        print item

ListView has the Item click listener callback. You should set the onItemClickListener in the ListView. Callback contains AdapterView and position as parameter. Which can give you the ListEntry.

lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                ListEntry entry= (ListEntry) parent.getAdapter().getItem(position);
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = entry.getMessage();
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

You can also use the Package Manager Console and invoke the Install-Package cmdlet by specifying the path to the directory that contains the package file in the -Source parameter:

Install-Package SomePackage -Source C:\PathToThePackageDir\

How about this one? Actually, this code returns 13 characters max, but it shorter than UUID.

import java.nio.ByteBuffer;
import java.util.UUID;

/**
 * Generate short UUID (13 characters)
 * 
 * @return short UUID
 */
public static String shortUUID() {
  UUID uuid = UUID.randomUUID();
  long l = ByteBuffer.wrap(uuid.toString().getBytes()).getLong();
  return Long.toString(l, Character.MAX_RADIX);
}

When I just run this as a page

<?php
echo '<script language="javascript">';
echo 'alert("message successfully sent")';
echo '</script>';
exit;

it works fine.

What version of PHP are you running?

Could you try echoing something else after: $testObject->split_for_sms($Chat);

Maybe it doesn't get to that part of the code? You could also try these with the other function calls to check where your program stops/is getting to.

Hope you get a bit further with this.

Cron is good for something that will run periodically, like every Saturday at 4am. There's also anacron, which works around power shutdowns, sleeps, and whatnot. As well as at.

But for a one-off solution, that doesn't require root or anything, you can just use date to compute the seconds-since-epoch of the target time as well as the present time, then use expr to find the difference, and sleep that many seconds.

The git rev-parse solution proposed by @Andy works fine if the date you're interested is the commit's date. If however you want to checkout based on the author's date, rev-parse won't work, because it doesn't offer an option to use that date for selecting the commits. Instead, you can use the following.

git checkout $(
  git log --reverse --author-date-order --pretty=format:'%ai %H' master |
  awk '{hash = $4} $1 >= "2016-04-12" {print hash; exit 0 }
)

(If you also want to specify the time use $1 >= "2016-04-12" && $2 >= "11:37" in the awk predicate.)

The problem is in the file :

style.css - line 721

#sub_footer {
    background: url("../images/exterior/sub_footer.png") repeat-x;
    background: -moz-linear-gradient(0% 100% 90deg,#102c40, #091925);
    background: -webkit-gradient(linear, 0% 0%, 0% 100%, from(#091925), to(#102c40));
    -moz-box-shadow: 3px 3px 4px #999999;
    -webkit-box-shadow: 3px 3px 4px #999999;
    box-shadow: 3px 3px 4px #999999;
    padding-top:10px;
    font-size:9px;
    min-height:40px;
}

remove the lines :

-moz-box-shadow: 3px 3px 4px #999999;
-webkit-box-shadow: 3px 3px 4px #999999;
box-shadow: 3px 3px 4px #999999; 

This basically gives a shadow gradient only to the footer. In Firefox, it is the first line that is causing the problem.

Although Apple recommends tel: in their docs for Mobile Safari, currently (iOS 4.3) it accepts callto: just the same. So I recommend using callto: on a generic web site as it works with both Skype and iPhone and I expect it will work on Android phones, too.

Update (June 2013)

This is still a matter of deciding what you want your web page to offer. On my websites I provide both tel: and callto: links (the latter labeled as being for Skype) since Desktop browsers on Mac don't do anything with tel: links while mobile Android doesn't do anything with callto: links. Even Google Chrome with the Google Talk plugin does not respond to tel: links. Still, I prefer offering both links on the desktop in case someone has gone to the trouble of getting tel: links to work on their computer.

If the site design dictated that I only provide one link, I'd use a tel: link that I would try to change to callto: on desktop browsers.

Use the REPLACE function.

eg: SELECT REPLACE ('t?es?t', '?', 'w');

There is an eclipse.ini (sts.ini) parameter that can help:

-Djava.net.useSystemProxies=true

A lot of effort wasted on this trivial setting each time I change the work environment... See one of the related bugs on eclipse bugzilla.

I wrote this function which I found to be helpful to prevent the user from being able to enter anything other than I was willing to accept. I also used keyboardType="decimal-pad" and my onChangeText={this.decimalTextChange}

  decimalTextChange = (distance) =>
{
    let decimalRegEx = new RegExp(/^\d*\.?\d*$/)
    if (distance.length === 0 || distance === "." || distance[distance.length - 1] === "."
        && decimalRegEx.test(distance)
    ) {
        this.setState({ distance })
    } else {
        const distanceRegEx = new RegExp(/^\s*-?(\d+(\.\d{ 1, 2 })?|\.\d{ 1, 2 })\s*$/)
        if (distanceRegEx.test(distance)) this.setState({ distance })
    }
}

The first if block is error handling for the event the user deletes all of the text, or uses a decimal point as the first character, or if they attempt to put in more than one decimal place, the second if block makes sure they can type in as many numbers as they want before the decimal place, but only up to two decimal places after the point.

You should install node.js with nvm, because that way you do not have to provide superuser privileges when installing global packages (you can simply execute "npm install -g packagename" without prepending 'sudo').

Brew is fantastic for other things, however. I tend to be biased towards Bower whenever I have the option to install something with Bower.

I am using husky and git-branch-is:

As of husky v1+:

// package.json

      "post-merge": "(git-branch-is master && npm version minor || 
  (git-branch-is dev && npm --no-git-tag-version version patch)",
    }
  }
}

Prior to husky V1:

"scripts": {
  ...
  "postmerge": "(git-branch-is master && npm version minor || 
  (git-branch-is dev && npm --no-git-tag-version version patch)",
  ...
},

Webpack or Vue.js

If you are using webpack or Vue.js, you can display this in the UI using Auto inject version - Webpack plugin

NUXT

In nuxt.config.js:

var WebpackAutoInject = require('webpack-auto-inject-version');

module.exports = {
  build: {
    plugins: [
      new WebpackAutoInject({
        // options
        // example:
        components: {
          InjectAsComment: false
        },
      }),
    ]
  },
}

Inside your template for example in the footer:

I had similar issue, the problem i faced was i added the selenium-server-standalone-3.141.59.jar under modulepath instead it should be under classpath

so select classpath via (project -> Properties -> Java Bbuild Path -> Libraries) add the downloaded latest jar

After adding it must be something like this

And appropriate driver for browser has to be downloaded for me i checked and downloaded the same version of chrom for chrome driver and added in the C:\Program Files\Java

And following is the code that worked fine for me

    public class TestuiAautomation {

                System.out.println(System.getProperty("webdriver.chrome.driver"));
                ChromeOptions chromeOptions = new ChromeOptions();
                chromeOptions.addArguments("no-sandbox");

You can check this out. Use foreach loop over a DataColumn provided with your DataTable.

 foreach(DataColumn column in dtTable.Columns)

I was trying to insert array like this

Upload::create($array);//$array was data to insert.

Issue has been resolve when I created Upload Model as

class Upload extends Eloquent {
    protected $guarded = array();  // Important
}

For anyone else that may encounter this problem and it is not solved by either of the options above, this is what worked for me.

1. Click on the website in IIS
2. Double Click on Authentication under IIS
3. Enable Anonymous Authentication

I had disabled this because we were using our own Auth, but that lead to this same problem and the accepted answer did not help in any way.

If your elements are distinct, then a simple set difference will do.

c = [1,2,3,4,'x',8,6,7,'x',9,'x']
z = list(set(c) - set(['x']))
print z
[1, 2, 3, 4, 6, 7, 8, 9]

I would like to argue one point - that you cannot augment the original assembly - using Mono.Cecil you can inject [InternalsVisibleTo(...)] to the 3pty assembly. Note there might be legal implications - you're messing with 3pty assembly and technical implications - if the assembly has strong name you either need to strip it or re-sign it with different key.

 Install-Package Mono.Cecil

And the code like:

static readonly string[] s_toInject = {
  // alternatively "MyAssembly, PublicKey=0024000004800000... etc."
  "MyAssembly"
};

static void Main(string[] args) {
  const string THIRD_PARTY_ASSEMBLY_PATH = @"c:\folder\ThirdPartyAssembly.dll";

   var parameters = new ReaderParameters();
   var asm = ModuleDefinition.ReadModule(INPUT_PATH, parameters);
   foreach (var toInject in s_toInject) {
     var ca = new CustomAttribute(
       asm.Import(typeof(InternalsVisibleToAttribute).GetConstructor(new[] {
                      typeof(string)})));
     ca.ConstructorArguments.Add(new CustomAttributeArgument(asm.TypeSystem.String, toInject));
     asm.Assembly.CustomAttributes.Add(ca);
   }
   asm.Write(@"c:\folder-modified\ThirdPartyAssembly.dll");
   // note if the assembly is strongly-signed you need to resign it like
   // asm.Write(@"c:\folder-modified\ThirdPartyAssembly.dll", new WriterParameters {
   //   StrongNameKeyPair = new StrongNameKeyPair(File.ReadAllBytes(@"c:\MyKey.snk"))
   // });
}

Following steps solved the issue for me..

• Copied the zip file into the Program Files folder and extracted to "apache-maven-3.6.3-bin".

• Then copied the path, C:\Program Files\apache-maven-3.6.3-bin\apache-maven-3.6.3

• Then created the new MAVEN_HOME variable within environmental variables with the above path.

Also added,

C:\Program Files\apache-maven-3.6.3-bin\apache-maven-3.6.3\bin

address to the "PATH" variable

A variable referencing an array is basically a pointer to its first element, so yes, you can legitimately return a pointer to an array, because thery're essentially the same thing. Check this out yourself:

#include <assert.h>

int main() {
  int a[] = {1, 2, 3, 4, 5}; 

  int* pArr = a;
  int* pFirstElem = &(a[0]);

  assert(a == pArr);
  assert(a == pFirstElem);

  return 0;
}

This also means that passing an array to a function should be done via pointer (and not via int in[5]), and possibly along with the length of the array:

int* test(int* in, int len) {
    int* out = in;
    return out;
}

That said, you're right that using pointers (without fully understanding them) is pretty dangerous. For example, referencing an array that was allocated on the stack and went out of scope yields undefined behavior:

#include <iostream>

using namespace std;

int main() {
  int* pArr = 0;
  {
    int a[] = {1, 2, 3, 4, 5};
    pArr = a; // or test(a) if you wish
  }
  // a[] went out of scope here, but pArr holds a pointer to it

  // all bets are off, this can output "1", output 1st chapter
  // of "Romeo and Juliet", crash the program or destroy the
  // universe
  cout << pArr[0] << endl; // WRONG!

  return 0;
}

So if you don't feel competent enough, just use std::vector.

[answer to the updated question]

The correct way to write your test function is either this:

void test(int* a, int* b, int* c, int len) {
  for (int i = 0; i < len; ++i) c[i] = a[i] + b[i];
}
...
int main() {
   int a[5] = {...}, b[5] = {...}, c[5] = {};
   test(a, b, c, 5);
   // c now holds the result
}

Or this (using std::vector):

#include <vector>

vector<int> test(const vector<int>& a, const vector<int>& b) {
  vector<int> result(a.size());
  for (int i = 0; i < a.size(); ++i) {
    result[i] = a[i] + b[i];
  }
  return result; // copy will be elided
}

Also late in the game, but doing some researches and stumbled across here. As others have mentioned, it's just almost close to impossible if it was automated, but if your design/requirement can involve in some cases (but not all the time) human interactions to review whether it is profane or not, you may consider ML. https://docs.microsoft.com/en-us/azure/cognitive-services/content-moderator/text-moderation-api#profanity is my current choice right now for multiple reasons:

• Supports many localization
• They keep updating the database, so I don't have to keep up with latest slangs or languages (maintenance issue)
• When there is a high probability (I.e. 90% or more) you can just deny it pragmatically
• You can observe for category which causes a flag that may or may not be profanity, and can have somebody review it to teach that it is or isn't profane.

For my need, it was/is based on public-friendly commercial service (OK, videogames) which other users may/will see the username, but the design requires that it has to go through profanity filter to reject offensive username. The sad part about this is the classic "clbuttic" issue will most likely occur since usernames are usually single word (up to N characters) of sometimes multiple words concatenated... Again, Microsoft's cognitive service will not flag "Assist" as Text.HasProfanity=true but may flag one of the categories probability to be high.

As the OP inquires, what about "a$$", here's a result when I passed it through the filter:, as you can see, it has determined it's not profane, but it has high probability that it is, so flags as recommendations of reviewing (human interactions).

When probability is high, I can either return back "I'm sorry, that name is already taken" (even if it isn't) so that it is less offensive to anti-censorship persons or something, if we don't want to integrate human review, or return "Your username have been notified to the live operation department, you may wait for your username to be reviewed and approved or chose another username". Or whatever...

By the way, the cost/price for this service is quite low for my purpose (how often does the username gets changed?), but again, for OP maybe the design demands more intensive queries and may not be ideal to pay/subscribe for ML-services, or cannot have human-review/interactions. It all depends on the design... But if design does fit the bill, perhaps this can be OP's solution.

If interested, I can list the cons in the comment in the future.

just need putting the datatype of the column in the datasource

dataSource: {
      data: empModel.Value,
      pageSize: 10,
      schema:  {
                model: {
                    fields: {
                        DOJ: { type: "date" }
                            }
                       }
               }  
           }

and then your statement column:

 columns: [
    {
        field: "Name",
        width: 90,
        title: "Name"
    },

    {
        field: "DOJ",
        width: 90,
        title: "DOJ",
        type: "date",
        format:"{0:MM-dd-yyyy}" 
    }
]

using lldb

(lldb) p JSONSerialization.data(withJSONObject: notification.request.content.userInfo, options: [])
(Data) $R16 = 375 bytes
(lldb) p String(data: $R16!, encoding: .utf8)!
(String) $R18 = "{\"aps\": \"some_text\"}"

//or
p String(data: JSONSerialization.data(withJSONObject: notification.request.content.userInfo, options: [])!, encoding: .utf8)!
(String) $R4 = "{\"aps\": \"some_text\"}"

The Spring framework's PathMatchingResourcePatternResolver is really awesome for these things:

private Resource[] getXMLResources() throws IOException
{
    ClassLoader classLoader = MethodHandles.lookup().getClass().getClassLoader();
    PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(classLoader);

    return resolver.getResources("classpath:x/y/z/*.xml");
}

Maven dependency:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>LATEST</version>
</dependency>

use the grid-system of boostrap , more information here

for example

<div class="row">
  <div class="col-md-4">here img</div>
  <div class="col-md-4">here text</div>
</div>

in this way when the page will shrink the second div(the text) will be found under the first(the image)

You are using a table variable i.e. you should declare the table. This is not a temporary table.

You create a temp table like so:

CREATE TABLE #customer
(
     Name varchar(32) not null
)

You declare a table variable like so:

DECLARE @Customer TABLE
(
      Name varchar(32) not null
)

Notice that a temp table is declared using # and a table variable is declared using a @. Go read about the difference between table variables and temp tables.

UPDATE:

Based on your comment below you are actually trying to create tables in a stored procedure. For this you would need to use dynamic SQL. Basically dynamic SQL allows you to construct a SQL Statement in the form of a string and then execute it. This is the ONLY way you will be able to create a table in a stored procedure. I am going to show you how and then discuss why this is not generally a good idea.

Now for a simple example (I have not tested this code but it should give you a good indication of how to do it):

CREATE PROCEDURE sproc_BuildTable 
    @TableName NVARCHAR(128)
   ,@Column1Name NVARCHAR(32)
   ,@Column1DataType NVARCHAR(32)
   ,@Column1Nullable NVARCHAR(32)
AS

   DECLARE @SQLString NVARCHAR(MAX)
   SET @SQString = 'CREATE TABLE '+@TableName + '( '+@Column1Name+' '+@Column1DataType +' '+@Column1Nullable +') ON PRIMARY '

   EXEC (@SQLString)
   GO

This stored procedure can be executed like this:

sproc_BuildTable 'Customers','CustomerName','VARCHAR(32)','NOT NULL'

There are some major problems with this type of stored procedure.

Its going to be difficult to cater for complex tables. Imagine the following table structure:

CREATE TABLE [dbo].[Customers] (
    [CustomerID] [int] IDENTITY(1,1) NOT NULL,
    [CustomerName] [nvarchar](64) NOT NULL,
    [CustomerSUrname] [nvarchar](64) NOT NULL,
    [CustomerDateOfBirth] [datetime] NOT NULL,
    [CustomerApprovedDiscount] [decimal](3, 2) NOT NULL,
    [CustomerActive] [bit] NOT NULL,
    CONSTRAINT [PK_Customers] PRIMARY KEY CLUSTERED 
    (
        [CustomerID] ASC
    ) WITH (PAD_INDEX  = OFF, STATISTICS_NORECOMPUTE  = OFF, IGNORE_DUP_KEY = OFF,      ALLOW_ROW_LOCKS  = ON, ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
) ON [PRIMARY]
GO

ALTER TABLE [dbo].[Customers] ADD CONSTRAINT [DF_Customers_CustomerApprovedDiscount] DEFAULT ((0.00)) FOR [CustomerApprovedDiscount]
GO 

This table is a little more complex than the first example, but not a lot. The stored procedure will be much, much more complex to deal with. So while this approach might work for small tables it is quickly going to be unmanageable.

Creating tables require planning. When you create tables they should be placed strategically on different filegroups. This is to ensure that you don't cause disk I/O contention. How will you address scalability if everything is created on the primary file group?

Could you clarify why you need tables to be created dynamically?

UPDATE 2:

Delayed update due to workload. I read your comment about needing to create a table for each shop and I think you should look at doing it like the example I am about to give you.

In this example I make the following assumptions:

1. It's an e-commerce site that has many shops
2. A shop can have many items (goods) to sell.
3. A particular item (good) can be sold at many shops
4. A shop will charge different prices for different items (goods)
5. All prices are in $ (USD)

Let say this e-commerce site sells gaming consoles (i.e. Wii, PS3, XBOX360).

Looking at my assumptions I see a classical many-to-many relationship. A shop can sell many items (goods) and items (goods) can be sold at many shops. Let's break this down into tables.

First I would need a shop table to store all the information about the shop.

A simple shop table might look like this:

CREATE TABLE [dbo].[Shop](
    [ShopID] [int] IDENTITY(1,1) NOT NULL,
    [ShopName] [nvarchar](128) NOT NULL,
    CONSTRAINT [PK_Shop] PRIMARY KEY CLUSTERED 
    (
      [ShopID] ASC
    ) WITH (
              PAD_INDEX  = OFF
              , STATISTICS_NORECOMPUTE  = OFF
              , IGNORE_DUP_KEY = OFF
              , ALLOW_ROW_LOCKS  = ON
              , ALLOW_PAGE_LOCKS  = ON
    ) ON [PRIMARY]
    ) ON [PRIMARY]

    GO

Let's insert three shops into the database to use during our example. The following code will insert three shops:

INSERT INTO Shop
SELECT 'American Games R US'
UNION
SELECT 'Europe Gaming Experience'
UNION
SELECT 'Asian Games Emporium'

If you execute a SELECT * FROM Shop you will probably see the following:

ShopID  ShopName
1           American Games R US
2           Asian Games Emporium
3           Europe Gaming Experience

Right, so now let's move onto the Items (goods) table. Since the items/goods are products of various companies I am going to call the table product. You can execute the following code to create a simple Product table.

CREATE TABLE [dbo].[Product](
    [ProductID] [int] IDENTITY(1,1) NOT NULL,
    [ProductDescription] [nvarchar](128) NOT NULL,
 CONSTRAINT [PK_Product] PRIMARY KEY CLUSTERED 
 (
     [ProductID] ASC
 )WITH (PAD_INDEX  = OFF
        , STATISTICS_NORECOMPUTE  = OFF
        , IGNORE_DUP_KEY = OFF
        ,     ALLOW_ROW_LOCKS  = ON
         , ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

GO

Let's populate the products table with some products. Execute the following code to insert some products:

INSERT INTO Product
SELECT 'Wii'
UNION 
SELECT 'PS3'
UNION 
SELECT 'XBOX360'

If you execute SELECT * FROM Product you will probably see the following:

ProductID   ProductDescription
1           PS3
2           Wii
3           XBOX360

OK, at this point you have both product and shop information. So how do you bring them together? Well we know we can identify the shop by its ShopID primary key column and we know we can identify a product by its ProductID primary key column. Also, since each shop has a different price for each product we need to store the price the shop charges for the product.

So we have a table that maps the Shop to the product. We will call this table ShopProduct. A simple version of this table might look like this:

CREATE TABLE [dbo].[ShopProduct](
[ShopID] [int] NOT NULL,
[ProductID] [int] NOT NULL,
[Price] [money] NOT NULL,
CONSTRAINT [PK_ShopProduct] PRIMARY KEY CLUSTERED 
 (
     [ShopID] ASC,
      [ProductID] ASC
 )WITH (PAD_INDEX  = OFF,
     STATISTICS_NORECOMPUTE  = OFF, 
     IGNORE_DUP_KEY = OFF, 
     ALLOW_ROW_LOCKS  = ON,
     ALLOW_PAGE_LOCKS  = ON) ON [PRIMARY]
  ) ON [PRIMARY]

 GO

So let's assume the American Games R Us shop only sells American consoles, the Europe Gaming Experience sells all consoles and the Asian Games Emporium sells only Asian consoles. We would need to map the primary keys from the shop and product tables into the ShopProduct table.

Here is how we are going to do the mapping. In my example the American Games R Us has a ShopID value of 1 (this is the primary key value) and I can see that the XBOX360 has a value of 3 and the shop has listed the XBOX360 for $159.99

By executing the following code you would complete the mapping:

INSERT INTO ShopProduct VALUES(1,3,159.99)

Now we want to add all product to the Europe Gaming Experience shop. In this example we know that the Europe Gaming Experience shop has a ShopID of 3 and since it sells all consoles we will need to insert the ProductID 1, 2 and 3 into the mapping table. Let's assume the prices for the consoles (products) at the Europe Gaming Experience shop are as follows: 1- The PS3 sells for $259.99 , 2- The Wii sells for $159.99 , 3- The XBOX360 sells for $199.99.

To get this mapping done you would need to execute the following code:

INSERT INTO ShopProduct VALUES(3,2,159.99) --This will insert the WII console into the mapping table for the Europe Gaming Experience Shop with a price of 159.99
INSERT INTO ShopProduct VALUES(3,1,259.99) --This will insert the PS3 console into the mapping table for the Europe Gaming Experience Shop with a price of 259.99
INSERT INTO ShopProduct VALUES(3,3,199.99) --This will insert the XBOX360 console into the mapping table for the Europe Gaming Experience Shop with a price of 199.99

At this point you have mapped two shops and their products into the mapping table. OK, so now how do I bring this all together to show a user browsing the website? Let's say you want to show all the product for the European Gaming Experience to a user on a web page – you would need to execute the following query:

SELECT      Shop.*
        , ShopProduct.*
        , Product.*
FROM         Shop 
INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
WHERE       Shop.ShopID=3

You will probably see the following results:

ShopID     ShopName                 ShopID  ProductID   Price   ProductID   ProductDescription
3          Europe Gaming Experience   3         1       259.99  1           PS3
3          Europe Gaming Experience   3         2       159.99  2           Wii
3          Europe Gaming Experience   3         3       199.99  3           XBOX360

Now for one last example, let's assume that your website has a feature which finds the cheapest price for a console. A user asks to find the cheapest prices for XBOX360.

You can execute the following query:

 SELECT     Shop.*
        , ShopProduct.*
        , Product.*
 FROM         Shop 
 INNER JOIN  ShopProduct ON Shop.ShopID = ShopProduct.ShopID 
 INNER JOIN  Product ON ShopProduct.ProductID = Product.ProductID
 WHERE      Product.ProductID =3  -- You can also use Product.ProductDescription = 'XBOX360'
 ORDER BY    Price ASC

This query will return a list of all shops which sells the XBOX360 with the cheapest shop first and so on.

You will notice that I have not added the Asian Games shop. As an exercise, add the Asian games shop to the mapping table with the following products: the Asian Games Emporium sells the Wii games console for $99.99 and the PS3 console for $159.99. If you work through this example you should now understand how to model a many-to-many relationship.

I hope this helps you in your travels with database design.

StringBuilder sb = new StringBuilder(name);
sb.setCharAt(0, Character.toUpperCase(sb.charAt(0)));  
return sb.toString();

window.frames['myIFrame'].document.getElementById('myIFrameElemId')

not working for me but I found another solution. Use:

window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId')

I checked it on Firefox and Chrome.

Use the string's constructor

basic_string(const charT* s,size_type n, const Allocator& a = Allocator());

EDIT:

OK, then if the C string length is not given explicitly, use the ctor:

basic_string(const charT* s, const Allocator& a = Allocator());

public void setHoursWorked(){
    hoursWorked = hours;
}

You haven't defined hours inside that method. hours is not passed in as a parameter, it's not declared as a variable, and it's not being used as a class member, so you get that error.

You should use .Load and not .LoadXML

MSDN Link

"The LoadXml method is for loading an XML string directly. You want to use the Load method instead."

ref : Link

You could use OrderedDict (requires Python 2.7) or higher.

Also, note that OrderedDict({'a': 1, 'b':2, 'c':3}) won't work since the dict you create with {...} has already forgotten the order of the elements. Instead, you want to use OrderedDict([('a', 1), ('b', 2), ('c', 3)]).

As mentioned in the documentation, for versions lower than Python 2.7, you can use this recipe.

This works for setting the value of the INPUT:

strftime('%Y-%m-%dT%H:%M:%S', time())

Here's a solution that is simple, short, easy to understand, and works perfectly for me. I needed to draw to the screen when another thread ends; but couldn't because the main thread has control of the screen. So:

(1) I created the global variable: boolean end1 = false; The thread sets it to true when ending. That is picked up in the mainthread by "postDelayed" loop, where it is responded to.

(2) My thread contains:

void myThread() {
    end1 = false;
    new CountDownTimer(((60000, 1000) { // milliseconds for onFinish, onTick
        public void onFinish()
        {
            // do stuff here once at end of time.
            end1 = true; // signal that the thread has ended.
        }
        public void onTick(long millisUntilFinished)
        {
          // do stuff here repeatedly.
        }
    }.start();

}

(3) Fortunately, "postDelayed" runs in the main thread, so that's where in check the other thread once each second. When the other thread ends, this can begin whatever we want to do next.

Handler h1 = new Handler();

private void checkThread() {
   h1.postDelayed(new Runnable() {
      public void run() {
         if (end1)
            // resond to the second thread ending here.
         else
            h1.postDelayed(this, 1000);
      }
   }, 1000);
}

(4) Finally, start the whole thing running somewhere in your code by calling:

void startThread()
{
   myThread();
   checkThread();
}

listStr = open("file_name","mode")

if "search element" in listStr:
    print listStr.index("search element")  # This will gives you the line number

It's not possible with a "normal" object, but you can do it with an ExpandoObject and the dynamic keyword:

dynamic person = new ExpandoObject();
person.FirstName = "Sam";
person.LastName = "Lewis";
person.Age = 42;
person.Foo = "Bar";
...

If you try to assign a property that doesn't exist, it is added to the object. If you try to read a property that doesn't exist, it will raise an exception. So it's roughly the same behavior as a dictionary (and ExpandoObject actually implements IDictionary<string, object>)

This interesting question is much harder than it looks, and it has not been answered. The question can be factored into 2 very different questions.

1 given N, find the list L of N's prime factors

2 given L, calculate number of unique combinations

All answers I see so far refer to #1 and fail to mention it is not tractable for enormous numbers. For moderately sized N, even 64-bit numbers, it is easy; for enormous N, the factoring problem can take "forever". Public key encryption depends on this.

Question #2 needs more discussion. If L contains only unique numbers, it is a simple calculation using the combination formula for choosing k objects from n items. Actually, you need to sum the results from applying the formula while varying k from 1 to sizeof(L). However, L will usually contain multiple occurrences of multiple primes. For example, L = {2,2,2,3,3,5} is the factorization of N = 360. Now this problem is quite difficult!

Restating #2, given collection C containing k items, such that item a has a' duplicates, and item b has b' duplicates, etc. how many unique combinations of 1 to k-1 items are there? For example, {2}, {2,2}, {2,2,2}, {2,3}, {2,2,3,3} must each occur once and only once if L = {2,2,2,3,3,5}. Each such unique sub-collection is a unique divisor of N by multiplying the items in the sub-collection.

Found something like that:

//javascript:
function playSound( url ){   
  document.getElementById("sound").innerHTML="<embed src='"+url+"' hidden=true autostart=true loop=false>";
} 

I don't have enough reputation to comment on a previous answer, so I'm posting a new answer to complement Jay Taylor's answer. Basically his answer will do the redirect, an implicit redirect though, meaning it will issue a 302 (temporary redirect), but since the question informs that the entire website will be served as https, then the appropriate redirect should be a 301 (permanent redirect).

redirect scheme https code 301 if !{ ssl_fc }

It seems a small change, but the impact might be huge depending on the website, with a permanent redirect we are informing the browser that it should no longer look for the http version from the start (avoiding future redirects) - a time saver for https sites. It also helps with SEO, but not dividing the juice of your links.

I think you're looking for the intersect function

array array_intersect ( array $array1 , array $array2 [, array $ ... ] )

array_intersect() returns an array containing all values of array1 that are present in all the arguments. Note that keys are preserved.

http://www.php.net/manual/en/function.array-intersect.php

Can also use

@(time(nil)).stringValue);

for timestamp in seconds.

And why not just count them ?

import sys
a = sys.argv
if len(a) = 1 :  
    # No arguments were given, the program name count as one
elif len(a) = 4 :
    # Three arguments were given
else :
    # another amount of arguments was given

Adding to @Hendrik Eichler Answer, the n vh uses n% of the viewport's initial containing block.

.element{
    height: 50vh; /* Would mean 50% of Viewport height */
    width:  75vw; /* Would mean 75% of Viewport width*/
}

Also, the viewport height is for devices of any resolution, the view port height, width is one of the best ways (similar to css design using % values but basing it on the device's view port height and width)

vh
Equal to 1% of the height of the viewport's initial containing block.

vw
Equal to 1% of the width of the viewport's initial containing block.

vi
Equal to 1% of the size of the initial containing block, in the direction of the root element’s inline axis.

vb
Equal to 1% of the size of the initial containing block, in the direction of the root element’s block axis.

vmin
Equal to the smaller of vw and vh.

vmax
Equal to the larger of vw and vh.

• Optional.map():

Takes every element and if the value exists, it is passed to the function:

Optional<T> optionalValue = ...;
Optional<Boolean> added = optionalValue.map(results::add);

Now added has one of three values: true or false wrapped into an Optional , if optionalValue was present, or an empty Optional otherwise.

If you don't need to process the result you can simply use ifPresent(), it doesn't have return value:

optionalValue.ifPresent(results::add); 

• Optional.flatMap():

Works similar to the same method of streams. Flattens out the stream of streams. With the difference that if the value is presented it is applied to function. Otherwise, an empty optional is returned.

You can use it for composing optional value functions calls.

Suppose we have methods:

public static Optional<Double> inverse(Double x) {
    return x == 0 ? Optional.empty() : Optional.of(1 / x);
}

public static Optional<Double> squareRoot(Double x) {
    return x < 0 ? Optional.empty() : Optional.of(Math.sqrt(x));
}

Then you can compute the square root of the inverse, like:

Optional<Double> result = inverse(-4.0).flatMap(MyMath::squareRoot);

or, if you prefer:

Optional<Double> result = Optional.of(-4.0).flatMap(MyMath::inverse).flatMap(MyMath::squareRoot);

If either the inverse() or the squareRoot() returns Optional.empty(), the result is empty.

var string = 'test- _ 0Test';
string.match(/^[-_ a-zA-Z0-9]+$/)

I had a similar problem. Using size_t was not working. I tried the other one which worked for me. (as below)

for(int i = things.size()-1;i>=0;i--)
{
 //...
}

Add runat to the element in the markup

<div id="formSpinner" runat="server">
    <img src="images/spinner.gif">
    <p>Saving...</p>
</div

Then you can get to the control's class attributes by using formSpinner.Attributes("class") It will only be a string, but you should be able to edit it.

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).

I am using JsonProperty attributes when serializing but ignoring them when deserializing using this ContractResolver:

public class IgnoreJsonPropertyContractResolver: DefaultContractResolver
    {
        protected override IList<JsonProperty> CreateProperties(Type type, MemberSerialization memberSerialization)
        {
            var properties = base.CreateProperties(type, memberSerialization);
            foreach (var p in properties) { p.PropertyName = p.UnderlyingName; }
            return properties;
        }
    }

The ContractResolver just sets every property back to the class property name (simplified from Shimmy's solution). Usage:

var airplane= JsonConvert.DeserializeObject<Airplane>(json, 
    new JsonSerializerSettings { ContractResolver = new IgnoreJsonPropertyContractResolver() });

could you please try below code

<c:forEach var="hash" items="${map['key']}">
        <option><c:out value="${hash}"/></option>
  </c:forEach>

We use a custom provider for multi language support and put all texts in a database table. It works well except we sometimes face caching problems when updating texts in the database without updating the web application.

I believe that this is one the most elegant solution.

import os

if os.name == 'nt':
    import msvcrt
    def getch():
        return msvcrt.getch().decode()
else:
    import sys, tty, termios
    fd = sys.stdin.fileno()
    old_settings = termios.tcgetattr(fd)
    def getch():
        try:
            tty.setraw(sys.stdin.fileno())
            ch = sys.stdin.read(1)
        finally:
            termios.tcsetattr(fd, termios.TCSADRAIN, old_settings)
        return ch

and then use it in the code:

if getch() == chr(ESC_ASCII_VALUE):
    print("ESC!")

I would do something like this:

;WITH x 
 AS (SELECT *, 
            Row_number() 
              OVER( 
                partition BY employeeid 
                ORDER BY datestart) rn 
     FROM   employeehistory) 
SELECT * 
FROM   x x1 
   LEFT OUTER JOIN x x2 
                ON x1.rn = x2.rn + 1 

Or maybe it would be x2.rn - 1. You'll have to see. In any case, you get the idea. Once you have the table joined on itself, you can filter, group, sort, etc. to get what you need.

Since others have covered the differences, I'll hit the uses.

TIFF is usually used by scanners. It makes huge files and is not really used in applications.

BMP is uncompressed and also makes huge files. It is also not really used in applications.

GIF used to be all over the web but has fallen out of favor since it only supports a limited number of colors and is patented.

JPG/JPEG is mainly used for anything that is photo quality, though not for text. The lossy compression used tends to mar sharp lines.

PNG isn't as small as JPEG but is lossless so it's good for images with sharp lines. It's in common use on the web now.

Personally, I usually use PNG everywhere I can. It's a good compromise between JPG and GIF.

If you use SQL Server 2008 or higher, use table valued parameters; for example:

CREATE PROCEDURE [dbo].[GetAccounts](@accountIds nvarchar)
AS
BEGIN
    SELECT * 
    FROM accountsTable 
    WHERE accountId IN (select * from @accountIds)
END

CREATE TYPE intListTableType AS TABLE (n int NOT NULL)

DECLARE @tvp intListTableType 

-- inserts each id to one row in the tvp table    
INSERT @tvp(n) VALUES (16509),(16685),(46173),(42925),(46167),(5511)

EXEC GetAccounts @tvp

SWIFT 3: Don't know if this is what you're looking for. But I compare a string to a current timestamp to see if my string is older that now.

func checkTimeStamp(date: String!) -> Bool {
        let dateFormatter: DateFormatter = DateFormatter()
        dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
        dateFormatter.locale = Locale(identifier:"en_US_POSIX")
        let datecomponents = dateFormatter.date(from: date)

        let now = Date()

        if (datecomponents! >= now) {
            return true
        } else {
            return false
        }
    }

To use it:

if (checkTimeStamp(date:"2016-11-21 12:00:00") == false) {
    // Do something
}

If you're using scss for your styles you can use a mixin to help generate the code. Your styles will quickly get out of hand if you put all the properties every time.

This is a very simple example - really nothing more than a proof of concept, you can extend this with multiple properties and rules as needed.

@mixin mat-table-columns($columns)
{
    .mat-column-
    {
        @each $colName, $props in $columns {

            $width: map-get($props, 'width');

            &#{$colName} 
            {
                flex: $width;
                min-width: $width;

                @if map-has-key($props, 'color') 
                {
                    color: map-get($props, 'color');
                }
            }  
        }
    }
}

Then in your component where your table is defined you just do this:

@include mat-table-columns((

    orderid: (width: 6rem, color: gray),
    date: (width: 9rem),
    items: (width: 20rem)

));

This generates something like this:

.mat-column-orderid[_ngcontent-c15] {
  flex: 6rem;
  min-width: 6rem;
  color: gray; }

.mat-column-date[_ngcontent-c15] {
  flex: 9rem;
  min-width: 9rem; }

In this version width becomes flex: value; min-width: value.

For your specific example you could add wrap: true or something like that as a new parameter.

To the latest setup and information if you have installed the Android Studio (i.e. 1.5) and trying to target SDK 4.0 then you may not be able to locate and setup the and AVD Emulator with SDK-vX.XX (with Google API's).

See following steps in order to download the required library and start with that. AVD Emulator setup -setting up Emulator for SDK4.0 with GoogleAPI so Map application can work- In Android Studio

But unfortunately above method did not work well on my side. And was not able to created Emulator with API Level 17 (SDK 4.2). So I followed this post that worked on my side well. The reason seems that the Android Studio Emulator creation window has limited options/features.

Even though question has been answered and accepted long ago, i just want to share my 2 cents:

You can imagine that at the very beginning of your file there is something like (just for explanation):

var module = new Module(...);
var exports = module.exports;

So whatever you do just keep in mind that module.exports and NOT exports will be returned from your module when you're requiring that module from somewhere else.

So when you do something like:

exports.a = function() {
    console.log("a");
}
exports.b = function() {
    console.log("b");
}

You are adding 2 function a and b to the object on which module.exports points too, so the typeof the returning result will be an object : { a: [Function], b: [Function] }

Of course, this is the same result you will get if you are using module.exports in this example instead of exports.

This is the case where you want your module.exports to behave like a container of exported values. Whereas, if you only want to export a constructor function then there is something you should know about using module.exports or exports;(Remember again that module.exports will be returned when you require something, not export).

module.exports = function Something() {
    console.log('bla bla');
}

Now typeof returning result is 'function' and you can require it and immediately invoke like:
var x = require('./file1.js')(); because you overwrite the returning result to be a function.

However, using exports you can't use something like:

exports = function Something() {
    console.log('bla bla');
}
var x = require('./file1.js')(); //Error: require is not a function

Because with exports, the reference doesn't point anymore to the object where module.exports points, so there is not a relationship between exports and module.exports anymore. In this case module.exports still points to the empty object {} which will be returned.

Accepted answer from another topic should also help: Does Javascript pass by reference?

Try out this example, the onclick is still called from your HTML, and event bubbling is stopped.

<div class="expandable-panel-heading">
<h2>
  <a id="ancherComplaint" href="#addComplaint" onclick="markActiveLink(this);event.stopPropagation();">ABC</a>
</h2>
</div>

Indeed, it would be nice if git-add had a --mode flag

git 2.9.x/2.10 (Q3 2016) actually will allow that (thanks to Edward Thomson):

git add --chmod=+x -- afile
git commit -m"Executable!"

That makes the all process quicker, and works even if core.filemode is set to false.

See commit 4e55ed3 (31 May 2016) by Edward Thomson (ethomson).
Helped-by: Johannes Schindelin (dscho).
^{(Merged by Junio C Hamano -- gitster -- in commit c8b080a, 06 Jul 2016)}

add: add --chmod=+x / --chmod=-x options

The executable bit will not be detected (and therefore will not be set) for paths in a repository with core.filemode set to false, though the users may still wish to add files as executable for compatibility with other users who do have core.filemode functionality.
For example, Windows users adding shell scripts may wish to add them as executable for compatibility with users on non-Windows.

Although this can be done with a plumbing command (git update-index --add --chmod=+x foo), teaching the git-add command allows users to set a file executable with a command that they're already familiar with.

Setting the body margins to 0, the width of the outer container to 100%, and using an inner container with 50px left/right margins seems to work.

<style>
body {
    margin: 0;
    padding: 0;
}

.full-width
{
    width: 100%;
}

.innerContainer
{
    margin: 0px 50px 0px 50px;
}
</style>

<body>
  <div class="full-width" style="background-color: #ff0000;">
    <div class="innerContainer" style="background-color: #00ff00;">
      content here
    </div>
  </div>
</body>

Here's an example:

char myChar = '|';
string myString = "||";

Chars are delimited by single quotes, and strings by double quotes.

The good news is C# switch statements work with strings!

switch (mytoken)
{
    case "==":
        //Something here.
        break;
    default:
        //Handle when no token is found.
        break;
}

As the other answers mentioned, dispatch_async from the main thread is fine.

However, depending on your use case, there is a side effect that you may consider a disadvantage: since the block is scheduled on a queue, it won't execute until control goes back to the run loop, which will have the effect of delaying your block's execution.

For example,

NSLog(@"before dispatch async");
dispatch_async(dispatch_get_main_queue(), ^{
    NSLog(@"inside dispatch async block main thread from main thread");
});
NSLog(@"after dispatch async");

Will print out:

before dispatch async
after dispatch async
inside dispatch async block main thread from main thread

For this reason, if you were expecting the block to execute in-between the outer NSLog's, dispatch_async would not help you.

Try looking at decode string encoded in utf-8 format in android but it doesn't look like your string is encoded with anything particular. What do you think the output should be?

There are certain things you have to take care:

• WebDriverWait inconjunction with ExpectedConditions as elementToBeClickable() returns the WebElement once it is located and clickable i.e. visible and enabled.
• In this process, WebDriverWait will ignore instances of NotFoundException that are encountered by default in the until condition.
• Once the duration of the wait expires on the desired element not being located and clickable, will throw a timeout exception.
• The different approach to address this issue are:

  • To invoke click() as soon as the element is returned, you can use:

    new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[@id='brandSlider']/div[1]/div/div/div/img)[50]"))).click();
    

  • To simply validate if the element is located and clickable, wrap up the WebDriverWait in a try-catch{} block as follows:

    try {
           new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[@id='brandSlider']/div[1]/div/div/div/img)[50]")));
           System.out.println("Element is clickable");
         }
    catch(TimeoutException e) {
           System.out.println("Element isn't clickable");
        }
    

  • If WebDriverWait returns the located and clickable element but the element is still not clickable, you need to invoke executeScript() method as follows:

    WebElement element = new WebDriverWait(driver, 10).until(ExpectedConditions.elementToBeClickable(By.xpath("(//div[@id='brandSlider']/div[1]/div/div/div/img)[50]"))); 
    ((JavascriptExecutor)driver).executeScript("arguments[0].click();", element);
    

As of iOS10 you can use

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root")!) 

to open general settings.

also you can add known urls(you can see them in the most upvoted answer) to it to open specific settings. For example the below one opens touchID and passcode.

UIApplication.sharedApplication().openURL(NSURL(string:"App-Prefs:root=TOUCHID_PASSCODE")!)

Runnable is often used to provide the code that a thread should run, but Runnable itself has nothing to do with threads. It's just an object with a run() method.

In Android, the Handler class can be used to ask the framework to run some code later on the same thread, rather than on a different one. Runnable is used to provide the code that should run later.

Start by get the content from file and trim the white spaces if any found in each line of the text document. That becomes the object passed to the where-object to go through the array looking at each member of the array with string length greater then 0. That object is passed to replace the content of the file you started with. It would probably be better to make a new file... Last thing to do is reads back the newly made file's content and see your awesomeness.

Another slight enhancement on CMS's answer. To easily allow for separate delays, you can use the following:

function makeDelay(ms) {
    var timer = 0;
    return function(callback){
        clearTimeout (timer);
        timer = setTimeout(callback, ms);
    };
};

If you want to reuse the same delay, just do

var delay = makeDelay(250);
$(selector1).on('keyup', function() {delay(someCallback);});
$(selector2).on('keyup', function() {delay(someCallback);});

If you want separate delays, you can do

$(selector1).on('keyup', function() {makeDelay(250)(someCallback);});
$(selector2).on('keyup', function() {makeDelay(250)(someCallback);});

If you don't give any position to parent then by default it takes static. If you want to understand that difference refer to this example

Example 1::

http://jsfiddle.net/Cr9KB/1/

   #mainall
{

    background-color:red;
    height:150px;
    overflow:scroll
}

Here parent class has no position so element is placed according to body.

Example 2::

http://jsfiddle.net/Cr9KB/2/

#mainall
{
    position:relative;
    background-color:red;
    height:150px;
    overflow:scroll
}

In this example parent has relative position hence element are positioned absolute inside relative parent.

@Milhous: the decimal format for rounding is excellent:

You can also use the

DecimalFormat df = new DecimalFormat("#.00000");
df.format(0.912385);

to make sure you have the trailing 0's.

I would add that this method is very good at providing an actual numeric, rounding mechanism - not only visually, but also when processing.

Hypothetical: you have to implement a rounding mechanism into a GUI program. To alter the accuracy / precision of a result output simply change the caret format (i.e. within the brackets). So that:

DecimalFormat df = new DecimalFormat("#0.######");
df.format(0.912385);

would return as output: 0.912385

DecimalFormat df = new DecimalFormat("#0.#####");
df.format(0.912385);

would return as output: 0.91239

DecimalFormat df = new DecimalFormat("#0.####");
df.format(0.912385);

would return as output: 0.9124

[EDIT: also if the caret format is like so ("#0.############") and you enter a decimal, e.g. 3.1415926, for argument's sake, DecimalFormat does not produce any garbage (e.g. trailing zeroes) and will return: 3.1415926 .. if you're that way inclined. Granted, it's a little verbose for the liking of some dev's - but hey, it's got a low memory footprint during processing and is very easy to implement.]

So essentially, the beauty of DecimalFormat is that it simultaneously handles the string appearance - as well as the level of rounding precision set. Ergo: you get two benefits for the price of one code implementation. ;)

I have also seen

if [ "x$variable" = "x" ]; then ...

which is obviously very robust and shell independent.

Also, there is a difference between "empty" and "unset". See How to tell if a string is not defined in a Bash shell script.

Take This as an alternate to startActivityforResult.But keep in mind that for such cases this approach can be expensive in terms of performance but in some cases you might need to use.

In Activity2,

@Override
public void onBackPressed() {
String data = mEditText.getText();
SharedPreferences sp = getSharedPreferences("LoginInfos", 0);
Editor editor = sp.edit();
editor.putString("email",data);
editor.commit();
}

In Activity1,

 @Override
public void onResume() {
SharedPreferences sp = getSharedPreferences("LoginInfos", 0);
String  dataFromOtherAct= sp.getString("email", "no email");
} 

In some languages True is just and alias for the number. You can learn more why this is by reading more about boolean logic.

1. It is a syntactical feature of the shell, so it has some special behavior that [ doesn't have. You no longer have to quote variables like mad because [[ handles empty strings and strings with whitespace more intuitively. For example, with [ you have to write

   if [ -f "$file" ]
   

   to correctly handle empty strings or file names with spaces in them. With [[ the quotes are unnecessary:

   if [[ -f $file ]]
   

2. Because it is a syntactical feature, it lets you use && and || operators for boolean tests and < and > for string comparisons. [ cannot do this because it is a regular command and &&, ||, <, and > are not passed to regular commands as command-line arguments.

3. It has a wonderful =~ operator for doing regular expression matches. With [ you might write

   if [ "$answer" = y -o "$answer" = yes ]
   

   With [[ you can write this as

   if [[ $answer =~ ^y(es)?$ ]]
   

   It even lets you access the captured groups which it stores in BASH_REMATCH. For instance, ${BASH_REMATCH[1]} would be "es" if you typed a full "yes" above.

4. You get pattern matching aka globbing for free. Maybe you're less strict about how to type yes. Maybe you're okay if the user types y-anything. Got you covered:

   if [[ $ANSWER = y* ]]
   

Keep in mind that it is a bash extension, so if you are writing sh-compatible scripts then you need to stick with [. Make sure you have the #!/bin/bash shebang line for your script if you use double brackets.

Try This:

SELECT systimestamp INTO time_db FROM dual ;

DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db);

Is it a spelling error in your closing tag ie:

</CustomErrors> instead of </CustomError>?

Make sure your package.json is valid...

I had the following error...

npm WARN Invalid name: "blah blah blah"

and that, similarly, caused devDependencies not to be installed.

FYI, changing the package.json "name" to blah-blah-blah fixed it.

I'll sometimes do this:

def draw_menu(options, selected_index):
    for i in range(len(options)):
        if i == selected_index:
            print " [*] %s" % options[i]
        else:
            print " [ ] %s" % options[i]

Though I tend to avoid this if it means I'll be saying options[i] more than a couple of times.

As I see PostgreSQL installer doesn't include 64 bit version of ODBC driver, which is necessary in your case. Download psqlodbc_09_00_0310-x64.zip and install it instead. I checked that on Win 7 64 bit and PostgreSQL 9.0.4 64 bit and it looks ok:

// If you want to change the selected Item to test2 using javascript. Try this one. // set the next option u want to select

var NewOprionValue = "Test2"

        var RemoveSelected = $("#MyDropDownList")[0].innerHTML.replace('selected', '');

I faced similar problem on windows server 2012 STD 64 bit , my problem is resolved after updating windows with all available windows updates.

In some cases, such as when you're outside The Loop, you may need to use get_queried_object_id() instead of get_the_ID().

$postID = get_queried_object_id();

Note: this was an experiment to see how UTF-8 encoding worked internally. The solution offered by vilicvane, to use a UTF8Encoding object that is initialised to throw an exception on decoding failure, is much simpler, and basically does the same thing.

I wrote this piece of code to differentiate between UTF-8 and Windows-1252. It shouldn't be used for gigantic text files though, since it loads the entire thing into memory and scans it completely. I used it for .srt subtitle files, just to be able to save them back in the encoding in which they were loaded.

The encoding given to the function as ref should be the 8-bit fallback encoding to use in case the file is detected as not being valid UTF-8; generally, on Windows systems, this will be Windows-1252. This doesn't do anything fancy like checking actual valid ascii ranges though, and doesn't detect UTF-16 even on byte order mark.

The theory behind the bitwise detection can be found here: https://ianthehenry.com/2015/1/17/decoding-utf-8/

Basically, the bit range of the first byte determines how many after it are part of the UTF-8 entity. These bytes after it are always in the same bit range.

Since I don't know how to control only the list marker size with CSS and no one's offered this yet, you can use :before content to generate the bullets:

li {
    list-style: none;
    font-size: 20px;
}

li:before {
    content:"·";
    font-size:120px;
    vertical-align:middle;
    line-height:20px;
}

Demo: http://jsfiddle.net/4wDL5/

The markers are limited to appearing "inside" with this particular CSS, although you could change it. It's definitely not the best option (browser must support generated content, so no IE6 or 7), but it might be the easiest - plus you can choose any character you want for the marker.

If you go the image route, see list-style-image.

I prefer to this approach because you can return the promise and use .then(successFunction, failFunction); anywhere you need to.

var promise = $.ajax({
    type: 'GET',
    dataType: 'json',
    url: url,
    timeout: 5000
  }).then(function( data, textStatus, jqXHR ) {
    alert('request successful');
  }, function( jqXHR, textStatus, errorThrown ) {
    alert('request failed');
});

//also access the success and fail using variable
promise.then(successFunction, failFunction);

Got this message with Spring AOP (seems to be coming from the CGLIB library). Clicking Ignore seems to work fine, I can still debug.

I just tried the same and came up with following solution:

public enum Countries {
    TEXAS,
    FLORIDA,
    OKLAHOMA,
    KENTUCKY;

    private static Countries[] list = Countries.values();

    public static Countries getCountry(int i) {
        return list[i];
    }

    public static int listGetLastIndex() {
        return list.length - 1;
    }
}

The class has it's own values saved inside an array, and I use the array to get the enum at indexposition. As mentioned above arrays begin to count from 0, if you want your index to start from '1' simply change these two methods to:

public static String getCountry(int i) {
    return list[(i - 1)];
}

public static int listGetLastIndex() {
    return list.length;
}

Inside my Main I get the needed countries-object with

public static void main(String[] args) {
   int i = Countries.listGetLastIndex();
   Countries currCountry = Countries.getCountry(i);
}

which sets currCountry to the last country, in this case Countries.KENTUCKY.

Just remember this code is very affected by ArrayOutOfBoundsExceptions if you're using hardcoded indicies to get your objects.

The httpd dæmon on OpenBSD uses the following stylesheet for all of its error messages, which presumably covers all the Comic Sans variations on non-Windows systems:

http://openbsd.su/src/usr.sbin/httpd/server_http.c#server_abort_http

810    style = "body { background-color: white; color: black; font-family: "
811        "'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif; }\n"
812        "hr { border: 0; border-bottom: 1px dashed; }\n";

E.g., try this:

font-family: 'Comic Sans MS', 'Chalkboard SE', 'Comic Neue', sans-serif;

A backslash needs to be escaped with another backslash.

print('\\')

Let's say you're making some kind of dashboard widget. As part of this, you want it to display the unread message count in your email box. So you make a little thread that will:

1. Connect to the mail server and ask how many unread messages you have.
2. Signal the GUI with the updated count.
3. Sleep for a little while.

When your widget starts up, it would create this thread, designate it a daemon, and start it. Because it's a daemon, you don't have to think about it; when your widget exits, the thread will stop automatically.

typeof foo === "undefined" is different from foo === undefined, never confuse them. typeof foo === "undefined" is what you really need. Also, use !== in place of !=

So the statement can be written as

function (data) {
  if (typeof data !== "undefined" && data !== null) {
    // some code here
  }
}

Edit:

You can not use foo === undefined for undeclared variables.

var t1;

if(typeof t1 === "undefined")
{
  alert("cp1");
}

if(t1 === undefined)
{
  alert("cp2");
}

if(typeof t2 === "undefined")
{
  alert("cp3");
}

if(t2 === undefined) // fails as t2 is never declared
{
  alert("cp4");
}

Instead of

css=#container

use

css=div.container:nth-of-type(1),css=div.container:nth-of-type(2)

Here's a short example, that creates and array of objects, and sorts numerically or alphabetically:

// Create Objects Array

var arrayCarObjects = [
{brand: "Honda",        topSpeed: 45},
{brand: "Ford",         topSpeed: 6},
{brand: "Toyota",       topSpeed: 240},
{brand: "Chevrolet",    topSpeed: 120},
{brand: "Ferrari",      topSpeed: 1000}
];

// Sort Objects Numerically

arrayCarObjects.sort((a, b) => (a.topSpeed - b.topSpeed));

// Sort Objects Alphabetically

arrayCarObjects.sort((a, b) => (a.brand > b.brand) ? 1 : -1);

Get-ChildItem $originalPath\* -Include @("*.gif", "*.jpg", "*.xls*", "*.doc*", "*.pdf*", "*.wav*", "*.ppt")

Since SSRS utilizes VB, you can do the following:

=Today() 'returns date only

If you were to use:

=Now() 'returns date and current timestamp

How about using a Browser plugin that gives you an overview of ANY html page. I have tried the following:

• HTML 5 Outliner for Chrome
• Headings Map for Firefox

They both work pretty well for IPython Notebooks. I was reluctant to use the previous solutions as they seem a bit unstable and ended up using these extensions.

Just type

document.querySelector('video').playbackRate = 1.25;

in JS console of your modern browser.

another alternative, just in case you want to have a shell script which creates the database if it does not exist and otherwise just keeps it as it is:

psql -U postgres -tc "SELECT 1 FROM pg_database WHERE datname = 'my_db'" | grep -q 1 || psql -U postgres -c "CREATE DATABASE my_db"

I found this to be helpful in devops provisioning scripts, which you might want to run multiple times over the same instance.

For those of you who would like an explanation:

-c = run command in database session, command is given in string
-t = skip header and footer
-q = silent mode for grep 
|| = logical OR, if grep fails to find match run the subsequent command

The accepted answer didn't work for me. To fix that issue, I had to right-click on the file that was locked, select repo-browser. This opened a popup with the files as they are on the SVN server. I then right-clicked on the locked file and selected break lock.

When I closed the repository browser, back on explorer I could finally commit!

In EF Core you no longer can execute "free" raw sql. You are required to define a POCO class and a DbSet for that class. In your case you will need to define Rank:

var ranks = DbContext.Ranks
   .FromSql("SQL_SCRIPT OR STORED_PROCEDURE @p0,@p1,...etc", parameters)
   .AsNoTracking().ToList();

As it will be surely readonly it will be useful to include the .AsNoTracking() call.

EDIT - Breaking change in EF Core 3.0:

DbQuery() is now obsolete, instead DbSet() should be used (again). If you have a keyless entity, i.e. it don't require primary key, you can use HasNoKey() method:

ModelBuilder.Entity<SomeModel>().HasNoKey()

Do not use ABSOLUTE PATH to refer to the name of the image for example: C:/xamp/www/Archivos/images/templatemo_image_02_opt_20160401-1244.jpg. You must use the reference to its location within webserver. For example using ../../Archivos/images/templatemo_image_02_opt_20160401-1244.jpg depending on where your process is running.

You can download a sigle file like that:

adb exec-out run-as debuggable.app.package.name cat files/file.mp4 > file.mp4

Before you download you might wan't to have a look at the file structure in your App-Directory. For this do the following steps THelper noticed above:

adb shell
run-as com.your.packagename 
cd files
ls -als .

The Android-Studio way Shahidul mentioned (https://stackoverflow.com/a/44089388/1256697) also work. For those who don't see the DeviceFile Explorer Option in the Menu: Be sure, to open the /android-Directory in Android Studio. E.g. react-native users have this inside of their Project-Folder right on the same Level as the /ios-Directory.

The following will work independent of your database privileges:

select * from all_triggers
where table_name = 'YOUR_TABLE'

The following alternate options may or may not work depending on your assigned database privileges:

select * from DBA_TRIGGERS

or

select * from USER_TRIGGERS

I have never encountered a C#->Java conversion tool. The syntax would be easy enough, but the frameworks are dramatically different. Even if there were a tool, I would strongly advise against it. I have worked on several "migration" projects, and can't say emphatically enough that while conversion seems like a good choice, conversion projects always always always turn in to money pits. It's not a shortcut, what you end up with is code that is not readable, and doesn't take advantage of the target language. speaking from personal experience, assume that a rewrite is the cheaper option.

NULL is not a built-in constant in the C or C++ languages. In fact, in C++ it's more or less obsolete, just use a plain literal 0 instead, the compiler will do the right thing depending on the context.

In newer C++ (C++11 and higher), use nullptr (as pointed out in a comment, thanks).

Otherwise, add

#include <stddef.h>

to get the NULL definition.

I recently found this App called Icon Set Creator in the App Store which is free, without ads, updated on new changes, straight forward and works just fine for every possible icon size in OSX, iOS and WatchOS:

In Icon Set Creator:

1. Drag your image into the view
2. Choose your target platform
3. Export the Icon Set folder

In XCode:

1. Navigate to the Assets.xcassets Folder
2. Delete the pre existing AppIcon
3. Right click -> Import your created Icon-Set as AppIcon and you're done

Listen to window:scroll event for window/document level scrolling and element's scroll event for element level scrolling.

window:scroll

@HostListener('window:scroll', ['$event'])
onWindowScroll($event) {

}

or

<div (window:scroll)="onWindowScroll($event)">

scroll

@HostListener('scroll', ['$event'])
onElementScroll($event) {

}

or

<div (scroll)="onElementScroll($event)">

@HostListener('scroll', ['$event']) won't work if the host element itself is not scroll-able.

Examples

• Using Event Binding
• Using HostListener

You don't have to, but some people like to explicitly initialize all variables (I do too). Especially those who program in a variety of languages, it's just easier to have the rule of always initializing your variables rather than deciding case-by-case/language-by-language.

For instance Java has default values for Boolean, int etc .. C on the other hand doesn't automatically give initial values, whatever happens to be in memory is what you end up with unless you assign a value explicitly yourself.

In your case above, as you discovered, the code works just as well without the initialization, esp since the variable is set in the next line which makes it appear particularly redundant. Sometimes you can combine both of those lines (declaration and initialization - as shown in some of the other posts) and get the best of both approaches, i.e., initialize the your variable with the result of the email1.equals (email2); operation.

Yes you can.

You don't have to download both Anaconda.

Only you need to download one of the version of Anaconda and need activate other version of Anaconda python.

If you have Python 3, you can set up a Python 2 kernel like this;

python2 -m pip install ipykernel

python2 -m ipykernel install --user

If you have Python 2,

python3 -m pip install ipykernel

python3 -m ipykernel install --user

Then you will be able to see both version of Python!

If you are using Anaconda Spyder then you should swap version here:

If you are using Jupiter then check here:

Note: If your Jupiter or Anaconda already open after installation you need to restart again. Then you will be able to see.

Remove pod name from Podfile then Open Terminal, set project folder path and Run pod update command.

NOTE: pod update will update all the libraries to the latest version and will also remove those libraries whose name have been removed from podfile.

Though you can use First(), Dictionaries do not have order per se. Please use OrderedDictionary instead. And then you can do FirstOrDefault. This way it will be meaningful.

You can also try /etc/redhat-release or /etc/fedora-release:

cat /etc/fedora-release

We use getters and setters:

• for reusability
• to perform validation in later stages of programming

Getter and setter methods are public interfaces to access private class members.

Encapsulation mantra

The encapsulation mantra is to make fields private and methods public.

Getter Methods: We can get access to private variables.

Setter Methods: We can modify private fields.

Even though the getter and setter methods do not add new functionality, we can change our mind come back later to make that method

• better;
• safer; and
• faster.

Anywhere a value can be used, a method that returns that value can be added. Instead of:

int x = 1000 - 500

use

int x = 1000 - class_name.getValue();

In layman's terms

Suppose we need to store the details of this Person. This Person has the fields name, age and sex. Doing this involves creating methods for name, age and sex. Now if we need create another person, it becomes necessary to create the methods for name, age, sex all over again.

Instead of doing this, we can create a bean class(Person) with getter and setter methods. So tomorrow we can just create objects of this Bean class(Person class) whenever we need to add a new person (see the figure). Thus we are reusing the fields and methods of bean class, which is much better.

I think floats may work best for you here, if you dont want the element to occupy the whole line, float it left should work.

.text span {
       background:rgba(165, 220, 79, 0.8);
       float: left;
       clear: left;
       padding:7px 10px;
       color:white;
    }

Note:Remove <br/>'s before using this off course.

If you are using Angular Reactive Forms you can create a file with a function - a validator. This will not allow only spaces to be entered.

import { AbstractControl } from '@angular/forms';
export function removeSpaces(control: AbstractControl) {
  if (control && control.value && !control.value.replace(/\s/g, '').length) {
    control.setValue('');
  }
  return null;
}

and then in your component typescript file use the validator like this for example.

this.formGroup = this.fb.group({
  name: [null, [Validators.required, removeSpaces]]
});

Its simple If you are passing String X from A to B.
A--> B

In Activity A
1) Create Intent
2) Put data in intent using putExtra method of intent
3) Start activity

Intent i = new Intent(A.this, B.class);
i.putExtra("MY_kEY",X);

In Activity B
inside onCreate method
1) Get intent object
2) Get stored value using key(MY_KEY)

Intent intent = getIntent();
String result = intent.getStringExtra("MY_KEY");

This is the standard way to send data from A to B. you can send any data type, it could be int, boolean, ArrayList, String[]. Based on the datatype you stored in Activity as key, value pair retrieving method might differ like if you are passing int value then you will call

intent.getIntExtra("KEY");

You can even send Class objects too but for that, you have to make your class object implement the Serializable or Parceable interface.

TransactionTooLargeException

How much data you can send across size. If data exceeds a certain amount in size then you might get TransactionTooLargeException. Suppose you are trying to send bitmap across the activity and if the size exceeds certain data size then you might see this exception.

Aside from the many answers already supplied to this question, a simple check on the local repo branches that exist in your machine and those that don't in the remote, will help. In which case you don't use the

git prune

command as many have suggested.

Simply delete the local branch

git branch -d <branch name without a remote tracking branch by the same name>

as shown in the attached screenshot using -D to force delete when you are sure that a local branch does not have a remote branch tracked.

public class Pair<K, V> {

    private final K element0;
    private final V element1;

    public static <K, V> Pair<K, V> createPair(K key, V value) {
        return new Pair<K, V>(key, value);
    }

    public Pair(K element0, V element1) {
        this.element0 = element0;
        this.element1 = element1;
    }

    public K getElement0() {
        return element0;
    }

    public V getElement1() {
        return element1;
    }

}

usage :

Pair<Integer, String> pair = Pair.createPair(1, "test");
pair.getElement0();
pair.getElement1();

Immutable, only a pair !

Actually, there's something wrong about all the other answers about r+ mode.

test.in file's content:

hello1
ok2
byebye3

And the py script's :

with open("test.in", 'r+')as f:
    f.readline()
    f.write("addition")

Execute it and the test.in's content will be changed to :

hello1
ok2
byebye3
addition

However, when we modify the script to :

with open("test.in", 'r+')as f:
    f.write("addition")

the test.in also do the respond:

additionk2
byebye3

So, the r+ mode will allow us to cover the content from the beginning if we did't do the read operation. And if we do some read operation, f.write()will just append to the file.

By the way, if we f.seek(0,0) before f.write(write_content), the write_content will cover them from the positon(0,0).

You need to re-factor the code into pieces. This doesn't stop execution, it just puts a delay in between the parts.

function partA() {
  ...
  window.setTimeout(partB,1000);
}

function partB() {
   ...
}

The way I handled this was switching the className of a label based on a condition. This way you only need one label and you can have different classes for different states... Hope that helps!

Well, this is easy to achieve .

Just build a GradientDrawable that comes from black and goes to a transparent color, than use parent relationship to place your shape close to the View that you want to have a shadow, then you just have to give any values to height or width .

Here is an example, this file have to be created inside res/drawable , I name it as shadow.xml :

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <gradient
        android:startColor="#9444"
        android:endColor="#0000"
        android:type="linear"
        android:angle="90"> <!-- Change this value to have the correct shadow angle, must be multiple from 45 -->
    </gradient>

</shape>

Place the following code above from a LinearLayout , for example, set the android:layout_width and android:layout_height to fill_parent and 2.3dp, you'll have a nice shadow effect on your LinearLayout .

<View
    android:id="@+id/shadow"
    android:layout_width="fill_parent"
    android:layout_height="2.3dp"  
    android:layout_above="@+id/id_from_your_LinearLayout" 
    android:background="@drawable/shadow">
</View>

Note 1: If you increase android:layout_height more shadow will be shown .

Note 2: Use android:layout_above="@+id/id_from_your_LinearLayout" attribute if you are placing this code inside a RelativeLayout, otherwise ignore it.

Hope it help someone.

In the upcoming Python 3.10 release schedule, with the new pairwise function it's possible to slide through pairs of elements and thus map on rolling pairs:

from itertools import pairwise

[y-x for (x, y) in pairwise([1, 3, 6, 7])]
# [2, 3, 1]

The intermediate result being:

pairwise([1, 3, 6, 7])
# [(1, 3), (3, 6), (6, 7)]

a very clean solution working in all browsers and without any framework is to asign a new Array and simply return it without the item you want to delete:

/**
 * @param {Array} array the original array with all items
 * @param {any} item the time you want to remove
 * @returns {Array} a new Array without the item
 */
var removeItemFromArray = function(array, item){
  /* assign a empty array */
  var tmp = [];
  /* loop over all array items */
  for(var index in array){
    if(array[index] !== item){
      /* push to temporary array if not like item */
      tmp.push(array[index]);
    }
  }
  /* return the temporary array */
  return tmp;
}

You want sys.exit(). From Python's docs:

>>> import sys
>>> print sys.exit.__doc__
exit([status])

Exit the interpreter by raising SystemExit(status).
If the status is omitted or None, it defaults to zero (i.e., success).
If the status is numeric, it will be used as the system exit status.
If it is another kind of object, it will be printed and the system
exit status will be one (i.e., failure).

So, basically, you'll do something like this:

from sys import exit

# Code!

exit(0) # Successful exit

The way that I usually go about it is using a temporary table. It's probably not computationally efficient but it seems to work ok! Here i am duplicating record 99 in its entirety, creating record 100.

CREATE TEMPORARY TABLE tmp SELECT * FROM invoices WHERE id = 99;

UPDATE tmp SET id=100 WHERE id = 99;

INSERT INTO invoices SELECT * FROM tmp WHERE id = 100;

Hope that works ok for you!

This was sort of tricky for me too, I did the following which worked pretty well.

• Download the appropriate Python .egg for setuptools (ie, for Python 2.6, you can get it here. Grab the correct one from the PyPI site here.)
• chmod the egg to be executable: chmod a+x [egg] (ie, for Python 2.6, chmod a+x setuptools-0.6c9-py2.6.egg)
• Run ./[egg] (ie, for Python 2.6, ./setuptools-0.6c9-py2.6.egg)

Not sure if you'll need to use sudo if you're just installing it for you current user. You'd definitely need it to install it for all users.

You can use <hr> for a vertical line as well.
Set the width to 1 and the size(height) as long as you want.
I used 500 in my example(demo):

With <hr width="1" size="500">

In SQL Server 2012, 2014:

USE mydb
GO

ALTER ROLE db_datareader ADD MEMBER MYUSER
GO
ALTER ROLE db_datawriter ADD MEMBER MYUSER
GO

In SQL Server 2008:

use mydb
go

exec sp_addrolemember db_datareader, MYUSER 
go
exec sp_addrolemember db_datawriter, MYUSER 
go

To also assign the ability to execute all Stored Procedures for a Database:

GRANT EXECUTE TO MYUSER;

To assign the ability to execute specific stored procedures:

GRANT EXECUTE ON dbo.sp_mystoredprocedure TO MYUSER;

There are 3 different methods depending on what I is my requirement and which version I am using.

Here are the methods..

1) Using Convert

DECLARE @DateTime DATETIME = GETDATE();
--Using Convert
SELECT
    CONVERT(NVARCHAR, @DateTime,120) AS 'myDateTime'
    ,CONVERT(NVARCHAR(10), @DateTime, 120) AS 'myDate'
    ,RIGHT(CONVERT(NVARCHAR, @DateTime, 120),8) AS 'myTime'

2) Using Cast (SQL Server 2008 and beyond)

SELECT
    CAST(@DateTime AS DATETIME2) AS 'myDateTime'
    ,CAST(@DateTime AS DATETIME2(3)) AS 'myDateTimeWithPrecision'
    ,CAST(@DateTime AS DATE) AS 'myDate'
    ,CAST(@DateTime AS TIME) AS 'myTime'
    ,CAST(@DateTime AS TIME(3)) AS 'myTimeWithPrecision'

3) Using Fixed-length character data type

DECLARE @myDateTime NVARCHAR(20) = CONVERT(NVARCHAR, @DateTime, 120);
DECLARE @myDate NVARCHAR(10) = CONVERT(NVARCHAR, @DateTime, 120);

SELECT
    @myDateTime AS 'myDateTime'
    ,@myDate AS 'myDate'

Unless someone can recommend a free tool to do this, you can achieve this with ReSharper:

ReSharper >> Options... >> Languages/C# >> Line Breaks and Wrapping

• Check "Wrap long lines"
• Set "Right Margin (columns)" to the required value (default is 120)

Hope that helps.

You just need to have the full expression inside the $. Basically, you need "meters $10^1$". You don't need usetex=True to do this (or most any mathematical formula).

You may also want to use a raw string (e.g. r"\t", vs "\t") to avoid problems with things like \n, \a, \b, \t, \f, etc.

For example:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set(title=r'This is an expression $e^{\sin(\omega\phi)}$',
       xlabel='meters $10^1$', ylabel=r'Hertz $(\frac{1}{s})$')
plt.show()

If you don't want the superscripted text to be in a different font than the rest of the text, use \mathregular (or equivalently \mathdefault). Some symbols won't be available, but most will. This is especially useful for simple superscripts like yours, where you want the expression to blend in with the rest of the text.

import matplotlib.pyplot as plt

fig, ax = plt.subplots()
ax.set(title=r'This is an expression $\mathregular{e^{\sin(\omega\phi)}}$',
       xlabel='meters $\mathregular{10^1}$',
       ylabel=r'Hertz $\mathregular{(\frac{1}{s})}$')
plt.show()

For more information (and a general overview of matplotlib's "mathtext"), see: http://matplotlib.org/users/mathtext.html

This blog post was helpful for me. I used the "Homebrew built Vim" solution, which in my case saved the new version in /usr/local/bin. At this point, the post suggested hiding the system vim, which didn't work for me, so I used an alias instead.

$ brew install vim
$ alias vim='/path/to/new/vim
$ which vim
vim: aliased to /path/to/new/vim

Answering your question in this format is quite challenging.

On the other hand you ask about navigation and then about current $state acting all weird.

For the first I'd say it's too broad question and for the second I'd say... well, you are doing something wrong or missing the obvious :)

Take the following controller:

app.controller('MainCtrl', function($scope, $state) {
  $scope.state = $state;
});

Where app is configured as:

app.config(function($stateProvider) {
  $stateProvider
    .state('main', {
        url: '/main',
        templateUrl: 'main.html',
        controller: 'MainCtrl'
    })
    .state('main.thiscontent', {
        url: '/thiscontent',
        templateUrl: 'this.html',
        controller: 'ThisCtrl'
    })
    .state('main.thatcontent', {
        url: '/thatcontent',
        templateUrl: 'that.html'
    });
});

Then simple HTML template having

<div>
  {{ state | json }}
</div>

Would "print out" e.g. the following

{ 
  "params": {}, 
  "current": { 
    "url": "/thatcontent", 
    "templateUrl": "that.html", 
    "name": "main.thatcontent" 
  }, 
  "transition": null
}

I put up a small example showing this, using ui.router and pascalprecht.translate for the menus. I hope you find it useful and figure out what is it you are doing wrong.

Plunker here http://plnkr.co/edit/XIW4ZE

Screencap

This happens when Elasticsearch thinks the disk is running low on space so it puts itself into read-only mode.

By default Elasticsearch's decision is based on the percentage of disk space that's free, so on big disks this can happen even if you have many gigabytes of free space.

The flood stage watermark is 95% by default, so on a 1TB drive you need at least 50GB of free space or Elasticsearch will put itself into read-only mode.

For docs about the flood stage watermark see https://www.elastic.co/guide/en/elasticsearch/reference/6.2/disk-allocator.html.

The right solution depends on the context - for example a production environment vs a development environment.

Solution 1: free up disk space

Freeing up enough disk space so that more than 5% of the disk is free will solve this problem. Elasticsearch won't automatically take itself out of read-only mode once enough disk is free though, you'll have to do something like this to unlock the indices:

$ curl -XPUT -H "Content-Type: application/json" https://[YOUR_ELASTICSEARCH_ENDPOINT]:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

Solution 2: change the flood stage watermark setting

Change the "cluster.routing.allocation.disk.watermark.flood_stage" setting to something else. It can either be set to a lower percentage or to an absolute value. Here's an example of how to change the setting from the docs:

PUT _cluster/settings
{
  "transient": {
    "cluster.routing.allocation.disk.watermark.low": "100gb",
    "cluster.routing.allocation.disk.watermark.high": "50gb",
    "cluster.routing.allocation.disk.watermark.flood_stage": "10gb",
    "cluster.info.update.interval": "1m"
  }
}

Again, after doing this you'll have to use the curl command above to unlock the indices, but after that they should not go into read-only mode again.

If error comes for ".settings/language.settings.xml" or any such file you don't need to git.

1. Team -> Commit -> Staged filelist, check if unwanted file exists, -> Right click on each-> remove from index.
2. From UnStaged filelist, check if unwanted file exists, -> Right click on each-> Ignore.

Now if Staged file list empty, and Unstaged file list all files are marked as Ignored. You can pull. Otherwise, follow other answers.

The GET (and HEAD) method should never be used to do anything that has side-effects. A side-effect might be updating the state of a web application, or it might be charging your credit card. If an action has side-effects another method (POST) should be used instead.

So, a user (or their browser) shouldn't be held accountable for something done by a GET. If some harmful or expensive side-effect occurred as the result of a GET, that would be the fault of the web application, not the user. According to the spec, a user agent must not automatically follow a redirect unless it is a response to a GET or HEAD request.

Of course, a lot of GET requests do have some side-effects, even if it's just appending to a log file. The important thing is that the application, not the user, should be held responsible for those effects.

The relevant sections of the HTTP spec are 9.1.1 and 9.1.2, and 10.3.

I've always thought that DLLs and shared objects are just different terms for the same thing - Windows calls them DLLs, while on UNIX systems they're shared objects, with the general term - dynamically linked library - covering both (even the function to open a .so on UNIX is called dlopen() after 'dynamic library').

They are indeed only linked at application startup, however your notion of verification against the header file is incorrect. The header file defines prototypes which are required in order to compile the code which uses the library, but at link time the linker looks inside the library itself to make sure the functions it needs are actually there. The linker has to find the function bodies somewhere at link time or it'll raise an error. It ALSO does that at runtime, because as you rightly point out the library itself might have changed since the program was compiled. This is why ABI stability is so important in platform libraries, as the ABI changing is what breaks existing programs compiled against older versions.

Static libraries are just bundles of object files straight out of the compiler, just like the ones that you are building yourself as part of your project's compilation, so they get pulled in and fed to the linker in exactly the same way, and unused bits are dropped in exactly the same way.

Try this:

$('#myAnchor')[0].click();

It works for me.

You could do it with JavaScript with something like this:

<input onblur="checkLength(this)" id="groupidtext" type="text" style="width: 100px;" maxlength="6" />
<!-- Or use event onkeyup instead if you want to check every character strike -->

function checkLength(el) {
  if (el.value.length != 6) {
    alert("length must be exactly 6 characters")
  }
}

Note this would work in older browsers which don't support HTML 5, but it relies on the user having JavaScript switched on.

This is the best way to do it:

df = df1.drop_duplicates().merge(df2.drop_duplicates(), on=df2.columns.to_list(), 
                   how='left', indicator=True)
df.loc[df._merge=='left_only',df.columns!='_merge']

Note that drop duplicated is used to minimize the comparisons. It would work without them as well. The best way is to compare the row contents themselves and not the index or one/two columns and same code can be used for other filters like 'both' and 'right_only' as well to achieve similar results. For this syntax dataframes can have any number of columns and even different indices. Only the columns should occur in both the dataframes.

Why this is the best way?

1. index.difference only works for unique index based comparisons
2. pandas.concat() coupled with drop_duplicated() is not ideal because it will also get rid of the rows which may be only in the dataframe you want to keep and are duplicated for valid reasons.

Try the points mentioned by @Robert Karl in this thread . If nothing works then you can surely see the logs through android device monitor.

1. Launch the android device monitor

2. select DDMS perspective ,

3. then select your device as shown in the screenshot .

You can use css and the :hover pseudo-property. Here is a simple demo. It uses the following css:

a span.tooltip {display:none;}
a:hover span.tooltip {position:absolute;top:30px;left:20px;display:inline;border:2px solid green;}

Note that older browsers have limited support for :hover.

I found that

dir > a.txt | type a.txt

didn't work (first few lines of dir listing only - suspect some sort of process forking and the second part, the 'type' command terminated before the dire listing had completed? ), so instead I used:

dir > z.txt && type z.txt

which did - sequential commands, one completes before the second starts.

try using a newer version of the maven compiler plugin:

    <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.2</version>
        <configuration>
            <source>1.7</source>
            <target>1.7</target>
        </configuration>
    </plugin>

also, specifying source file encoding in maven is better done globally:

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

EDIT: As this answer is still getting attention i'd just like to point out that the latest values (as of latest edit) are 3.2 for maven compiler plugin and 1.8 for java, as questions about compiling java 8 code via maven are bound to appear soon :-)

If you only need to remove duplicates then use DISTINCT. GROUP BY should be used to apply aggregate operators to each group

GROUP BY v DISTINCT

I have 2 Nexus 4 devices. One was connecting to ADB without any problems, the second one never showed up when I used the adb devices command. An additional symptom was, that the second phone did not show up as a portable device in Windows Explorer when the phone was set to Media mode.

At some point I found that a temporary solution for the second Nexus was to switch it to PTP mode. Then it was found by the adb devices command. The weired thing was that the first phone worked in both modes all the time!

Finally I found this solution that now allows me to connect both phones in both modes:

• set USB mode of the phone to MTP (Media)
  Using PC device manager uninstall the device ->Android Device ->Android ADB Interface
  Make sure to check the box "Delete the driver software"!

• then set the USB mode of the phone to PTP (Camera)
  Using PC device manager uninstall the device ->Portable Devies ->Nexus 4

• Then unplug the USB and plug it back in (ensuring that its set to MTP (Media) and I found that the device was correctly registered in Device manager as a ->Portable Devies ->Nexus 4

Solution found at: http://forum.xda-developers.com/showthread.php?p=34910298#post34910298

If you have a similar problem to connect your Nexus to ADB then I recommend to first switch it to PTP mode. If your problem vanishes with that step, I recommend to go through the additional steps listed above as MTP will probably be the mode you will want to set your phone to most of the time.

You can use int casting which allows the base specification.

None of the previous answers (to this date) gives the correct difference in days between two dates.

The one that comes closest is by thatdankent. A full answer would convert to_i and then divide:

(Time.now.to_i - 23.hours.ago.to_i) / 86400
>> 0

(Time.now.to_i - 25.hours.ago.to_i) / 86400
>> 1

(Time.now.to_i - 1.day.ago.to_i) / 86400
>> 1

In the question's specific example, one should not parse to Date if the time passed is relevant. Use Time.parse instead.

    public ActionResult GetExcelColumn()
    {            
            List<string> lstAppendColumn = new List<string>();
            lstAppendColumn.Add("First");
            lstAppendColumn.Add("Second");
            lstAppendColumn.Add("Third");
  return Json(new { lstAppendColumn = lstAppendColumn,  Status = "Success" }, JsonRequestBehavior.AllowGet);
            }
        }

How about this:

def yes(prompt = 'Please enter Yes/No: '):
while True:
    try:
        i = raw_input(prompt)
    except KeyboardInterrupt:
        return False
    if i.lower() in ('yes','y'): return True
    elif i.lower() in ('no','n'): return False

Short answer is no.

As you note the browsers derive type from the file extension. Mac preview also seems to run off the extension. I'm assuming its because its faster reading the file name contained in the pointer, rather than looking up and reading the file on disk.

I made a copy of a jpg renamed with png.

I was able to consistently get the following from both images in chrome (should work in modern browsers).

ÿØÿàJFIFÿþ;CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 90

Which you could hack out a String.indexOf('jpeg') check for image type.

The ambigious line I forgot to comment in the example

console.log( /^(.*)$/m.exec(window.atob( image.src.split(',')[1] )) );

• Splits the base64 encoded img data, leaving on the image
• Base64 decodes the image
• Matches only the first line of the image data

The fiddle code uses base64 decode which wont work in IE9, I did find a nice example using VB script that works in IE http://blog.nihilogic.dk/2008/08/imageinfo-reading-image-metadata-with.html

The code to load the image was taken from Joel Vardy, who is doing some cool image canvas resizing client side before uploading which may be of interest https://joelvardy.com/writing/javascript-image-upload

If you want to add more than one:

hash = {:a => 1, :b => 2}
hash.merge! :c => 3, :d => 4
p hash

Okay. So this is a very old question and has great answers from that time. But a lot has changed since then.

Now, in 2020, if you are working with Kotlin and want to change the fragment then you can do the following.

1. Add Kotlin extension for Fragments to your project.

In your app level build.gradle file add the following,

dependencies {
    def fragment_version = "1.2.5"

    // Kotlin
    implementation "androidx.fragment:fragment-ktx:$fragment_version"
    // Testing Fragments in Isolation
    debugImplementation "androidx.fragment:fragment-testing:$fragment_version"
}

2. Then simple code to replace the fragment,

In your activity

supportFragmentManager.commit {
    replace(R.id.frame_layout, YourFragment.newInstance(), "Your_TAG")
    addToBackStack(null)
}
