I think you want something like

var count = context.MyTable.Count(t => t.MyContainer.ID == '1');

Update: you can read the more complex answer, which contains more methods and information.

There exists a couple of scripts, which can be used as simple package managers. But as far as I know, none of them allows you to upgrade packages, because it’s not an easy task on Windows since there is not possible to overwrite files in use. So you have to close all Cygwin instances first and then you can use Cygwin’s native setup.exe (which itself does the upgrade via “replace after reboot” method, when files are in use).

apt-cyg

The best one for me. Simply because it’s one of the most recent. It works correctly for both platforms - x86 and x86_64. There exists a lot of forks with some additional features. For example the kou1okada fork is one of improved versions.

Cygwin’s setup.exe

It has also command line mode. Moreover it allows you to upgrade all installed packages at once.

setup.exe-x86_64.exe -q --packages=bash,vim

Example use:

setup.exe-x86_64.exe -q --packages="bash,vim"

You can create an alias for easier use, for example:

alias cyg-get="/cygdrive/d/path/to/cygwin/setup-x86_64.exe -q -P"

Then you can for example install the Vim package with:

cyg-get vim

Well that's a very interesting question. I would divide the two constants in your question according to their type. int MAX_COUNT is a constant of primitive type while Logger log is a non-primitive type.

When we are making use of a constant of a primitive types, we are mutating the constant only once in our code public static final in MAX_COUNT = 10 and we are just accessing the value of the constant elsewhere for(int i = 0; i<MAX_COUNT; i++). This is the reason we are comfortable with using this convention.

While in the case of non-primitive types, although, we initialize the constant in only one place private static final Logger log = Logger.getLogger(MyClass.class);, we are expected to mutate or call a method on this constant elsewhere log.debug("Problem"). We guys don't like to put a dot operator after the capital characters. After all we have to put a function name after the dot operator which is surely going to be a camel-case name. That's why LOG.debug("Problem") would look awkward.

Same is the case with String types. We are usually not mutating or calling a method on a String constant in our code and that's why we use the capital naming convention for a String type object.

To use the window object is not a good idea. As I see in comments,

'use strict';

function showMessage() {
    window.say_hello = 'hello!';
}

console.log(say_hello);

This will throw an error to use the say_hello variable we need to first call the showMessage function.

Simply, change the root folder name for your solution in your local machine, it will disconnect automatically.

You could use setInterval for this.

<script type="text/javascript">
function myFunction () {
    console.log('Executed!');
}

var interval = setInterval(function () { myFunction(); }, 60000);
</script>

Disable the timer by setting clearInterval(interval).

I previously had this problem with my EC2 instance (I was serving couchdb to serve resources -- am considering Amazon's S3 for the future).

One thing to check (assuming Ec2) is that the couchdb port is added to your open ports within your security policy.

I specifically encountered

"[Errno 111] Connection refused"

over EC2 when the instance was stopped and started. The problem seems to be a pidfile race. The solution for me was killing couchdb (entirely and properly) via:

pkill -f couchdb

and then restarting with:

/etc/init.d/couchdb restart

Do simple compare > and <.

if (dateA>dateB && dateA<dateC)
    //do something

If you care only on time:

if (dateA.TimeOfDay>dateB.TimeOfDay && dateA.TimeOfDay<dateC.TimeOfDay)
    //do something

Change branch, discarding all local modifications

git checkout -f 9-sign-in-out 

Rename the current branch to master, discarding current master

git branch -M master

As of Jquery 3.0 and above .bind has been deprecated and they prefer using .on instead. As @Blazemonger answered earlier that it may be removed and its for sure that it will be removed. For the older versions .bind would also call .on internally and there is no difference between them. Please also see the api for more detail.

jQuery API documentation for .bind()

Try this:

.slideContainer {_x000D_
    overflow-x: scroll;_x000D_
    white-space: nowrap;_x000D_
}_x000D_
.slide {_x000D_
    display: inline-block;_x000D_
    width: 600px;_x000D_
    white-space: normal;_x000D_
}

<div class="slideContainer">_x000D_
    <span class="slide">Some content</span>_x000D_
    <span class="slide">More content. Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</span>_x000D_
    <span class="slide">Even more content!</span>_x000D_
</div>

Note that you can omit .slideContainer { overflow-x: scroll; } (which browsers may or may not support when you read this), and you'll get a scrollbar on the window instead of on this container.

The key here is display: inline-block. This has decent cross-browser support nowadays, but as usual, it's worth testing in all target browsers to be sure.

Old question, but some of us are in git-posh (powershell). This is the solution for that:

git ls-files -ci --exclude-standard | foreach { git rm --cached $_ }

You can use the re library

Assuming that you are able to load your full txt-file. You then define a list of unwanted nicknames and then substitute them with an empty string "".

# Delete unwanted characters
import re

# Read, then decode for py2 compat.
path_to_file = 'data/nicknames.txt'
text = open(path_to_file, 'rb').read().decode(encoding='utf-8')

# Define unwanted nicknames and substitute them
unwanted_nickname_list = ['SourDough']
text = re.sub("|".join(unwanted_nickname_list), "", text)

I have created this JQuery function

/**
 * Draw a table from json array
 * @param {array} json_data_array Data array as JSON multi dimension array
 * @param {array} head_array Table Headings as an array (Array items must me correspond to JSON array)
 * @param {array} item_array JSON array's sub element list as an array
 * @param {string} destinaion_element '#id' or '.class': html output will be rendered to this element
 * @returns {string} HTML output will be rendered to 'destinaion_element'
 */

function draw_a_table_from_json(json_data_array, head_array, item_array, destinaion_element) {
    var table = '<table>';
    //TH Loop
    table += '<tr>';
    $.each(head_array, function (head_array_key, head_array_value) {
        table += '<th>' + head_array_value + '</th>';
    });
    table += '</tr>';
    //TR loop
    $.each(json_data_array, function (key, value) {

        table += '<tr>';
        //TD loop
        $.each(item_array, function (item_key, item_value) {
            table += '<td>' + value[item_value] + '</td>';
        });
        table += '</tr>';
    });
    table += '</table>';

    $(destinaion_element).append(table);
}
;

This is probably the simplest way of doing it:

sed -r 's/\s+//g' filename > output
mv ouput filename

According to the W3C File API specification, the File constructor requires 2 (or 3) parameters.

So to create a empty file do:

var f = new File([""], "filename");

• The first argument is the data provided as an array of lines of text;
• The second argument is the filename ;

• The third argument looks like:

  var f = new File([""], "filename.txt", {type: "text/plain", lastModified: date})
  

It works in FireFox, Chrome and Opera, but not in Safari or IE/Edge.

I think is that the best is to install the virtual environment in a path inside the repository folder, maybe is better inclusive to use a subdirectory dedicated to the environment (I have deleted accidentally my entire project when force installing a virtual environment in the repository root folder, good that I had the project saved in its latest version in Github).

Either the automated installer, or the documentation should indicate the virtualenv path as a relative path, this way you won't run into problems when sharing the project with other people. About the packages, the packages used should be saved by pip freeze -r requirements.txt.

This is just a quick review of how fPDF stands up against tcPDF in the area of performance at each libraries most basic functions.

SPEED TEST

17.0366 seconds to process 2000 PDF files using fPDF || 79.5982 seconds to process 2000 PDF files using tcPDF

FILE SIZE CHECK (in bytes)

788 fPDF || 1,860 tcPDF

The code used was as identical as possible and renders just a clean PDF file with no text. This is also using the latest version of each library as of June 22, 2011.

I decided to just build controls dictionaries. Harder to maintain, might run faster than the recursive FindControl().

protected void Page_Load(object sender, EventArgs e)
{
  this.BuildControlDics();
}

private void BuildControlDics()
{
  _Divs = new Dictionary<MyEnum, HtmlContainerControl>();
  _Divs.Add(MyEnum.One, this.divOne);
  _Divs.Add(MyEnum.Two, this.divTwo);
  _Divs.Add(MyEnum.Three, this.divThree);

}

And before I get down-thumbs for not answering the OP's question...

Q: Now, my question is that is there any other way/solution to find the nested control in ASP.NET? A: Yes, avoid the need to search for them in the first place. Why search for things you already know are there? Better to build a system allowing reference of known objects.

This is more narrowly-tailored. When I do this I usually have a comma-delimited list of unique ids (INT or BIGINT), which I want to cast as a table to use as an inner join to another table that has a primary key of INT or BIGINT. I want an in-line table-valued function returned so that I have the most efficient join possible.

Sample usage would be:

 DECLARE @IDs VARCHAR(1000);
 SET @IDs = ',99,206,124,8967,1,7,3,45234,2,889,987979,';
 SELECT me.Value
 FROM dbo.MyEnum me
 INNER JOIN dbo.GetIntIdsTableFromDelimitedString(@IDs) ids ON me.PrimaryKey = ids.ID

I stole the idea from http://sqlrecords.blogspot.com/2012/11/converting-delimited-list-to-table.html, changing it to be in-line table-valued and cast as INT.

create function dbo.GetIntIDTableFromDelimitedString
    (
    @IDs VARCHAR(1000)  --this parameter must start and end with a comma, eg ',123,456,'
                        --all items in list must be perfectly formatted or function will error
)
RETURNS TABLE AS
 RETURN

SELECT
    CAST(SUBSTRING(@IDs,Nums.number + 1,CHARINDEX(',',@IDs,(Nums.number+2)) - Nums.number - 1) AS INT) AS ID 
FROM   
     [master].[dbo].[spt_values] Nums
WHERE Nums.Type = 'P' 
AND    Nums.number BETWEEN 1 AND DATALENGTH(@IDs)
AND    SUBSTRING(@IDs,Nums.number,1) = ','
AND    CHARINDEX(',',@IDs,(Nums.number+1)) > Nums.number;

To get a Buffered Image with ImageIO.read is a very heavy method, as it's creating a complete uncompressed copy of the image in memory. For png's you may also use pngj and the code:

if (png)
    PngReader pngr = new PngReader(file);
    width = pngr.imgInfo.cols;
    height = pngr.imgInfo.rows;
    pngr.close();
}

i had the same issue and find the solution lately.

you should check if your route is rather inside a route::group

like here:

Route::group(['prefix' => 'Auth', 'as' => 'Auth.', 'namespace' => 'Auth', 'middleware' => 'Auth']

if so you should use it in the view file. like here:

!! Form::model(Auth::user(), ['method' => 'PATCH', 'route' => 'Auth.preferences/' . Auth::user()->id]) !!}

Simply add the following:

from sys import *
path_to_current_file = sys.argv[0]
print(path_to_current_file)

Or:

from sys import *
print(sys.argv[0])

EntityManager interface is similar to sessionFactory in hibernate. EntityManager under javax.persistance package but session and sessionFactory under org.hibernate.Session/sessionFactory package.

Entity manager is JPA specific and session/sessionFactory are hibernate specific.

A cookie is just another HTTP header. You can always set it while making a HTTP call with the apache library or with HTTPUrlConnection. Either way you should be able to read and set HTTP cookies in this fashion.

You can read this article for more information.

I can share my peace of code to demonstrate how easy you can make it.

public static String getServerResponseByHttpGet(String url, String token) {

        try {
            HttpClient client = new DefaultHttpClient();
            HttpGet get = new HttpGet(url);
            get.setHeader("Cookie", "PHPSESSID=" + token + ";");
            Log.d(TAG, "Try to open => " + url);

            HttpResponse httpResponse = client.execute(get);
            int connectionStatusCode = httpResponse.getStatusLine().getStatusCode();
            Log.d(TAG, "Connection code: " + connectionStatusCode + " for request: " + url);

            HttpEntity entity = httpResponse.getEntity();
            String serverResponse = EntityUtils.toString(entity);
            Log.d(TAG, "Server response for request " + url + " => " + serverResponse);

            if(!isStatusOk(connectionStatusCode))
                return null;

            return serverResponse;

        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (Exception e) {
            e.printStackTrace();
        }

        return null;
    }

I searched a lot about restful ws security and we also ended up with using token via cookie from client to server to authenticate the requests . I used spring security for authorization of requests in service because I had to authenticate and authorized each request based on specified security policies that has already been in DB.

The problem is that readlines is a list of strings, each of which is a line of filename. Perhaps you meant:

for line in readlines:
    Type = line.split(",")
    x = Type[1]
    y = Type[2]
    print(x,y)

This should do the trick

'g' in df.index

Java does not allow extending multiple classes.

Let's assume C class is extending A and B classes. Then if suppose A and B classes have method with same name(Ex: method1()). Consider the code:

C obj1 = new C(); obj1.method1(); - here JVM will not understand to which method it need to access. Because both A and B classes have this method. So we are putting JVM in dilemma, so that is the reason why multiple inheritance is removed from Java. And as said implementing multiple classes will resolve this issue.

Hope this has helped.

The example below is based on your comments. It uses a List of keywords, which will be searched in a given String using word boundaries. It uses StringUtils from Apache Commons Lang to build the regular expression and print the matched groups.

String text = "I will come and meet you at the woods 123woods and all the woods";

List<String> tokens = new ArrayList<String>();
tokens.add("123woods");
tokens.add("woods");

String patternString = "\\b(" + StringUtils.join(tokens, "|") + ")\\b";
Pattern pattern = Pattern.compile(patternString);
Matcher matcher = pattern.matcher(text);

while (matcher.find()) {
    System.out.println(matcher.group(1));
}

If you are looking for more performance, you could have a look at StringSearch: high-performance pattern matching algorithms in Java.

I use the AbsoluteUri and you can get it like this:

string myURI = Request.Url.AbsoluteUri;
 if (!WebSecurity.IsAuthenticated) {
        Response.Redirect("~/Login?returnUrl="
            + Request.Url.AbsoluteUri );

Then after you login:

var returnUrl = Request.QueryString["returnUrl"];
 if(WebSecurity.Login(username,password,true)){
                Context.RedirectLocal(returnUrl);

It works well for me.

I found that JimTheDev's answer only worked when the state definition had cache:false set. With the view cached, you can do $ionicHistory.clearCache() and then $state.go('app.fooDestinationView') if you're navigating from one state to the one that is cached but needs refreshing.

See my answer here as it requires a simple change to Ionic and I created a pull request: https://stackoverflow.com/a/30224972/756177

Maybe something a bit simpler:

public class Fonts {
  public static HashSet<String,Typeface> fonts = new HashSet<>();

  public static Typeface get(Context context, String file) {
    if (! fonts.contains(file)) {
      synchronized (this) {
        Typeface typeface = Typeface.createFromAsset(context.getAssets(), name);
        fonts.put(name, typeface);
      }
    }
    return fonts.get(file);
  }
}

// Usage
Typeface myFont = Fonts.get("arial.ttf");

(Note this code is untested, but in general this approach should work well.)

Note: if you are trying to get this information for tables that are in a different SCHEMA use the all_tab_columns view, we have this problem as our Applications use a different SCHEMA for security purposes.

use the following:

EG:

SELECT
    data_length 
FROM
    all_tab_columns 
WHERE
    upper(table_name) = 'MY_TABLE_NAME' AND upper(column_name) = 'MY_COL_NAME'

Say st is your unformatted string, then run

st_nodigits=''.join(i for i in st if i.isalpha())

as mentioned above. But my guess that you need something very simple so say s is your string and st_res is a string without digits, then here is your code

l = ['0','1','2','3','4','5','6','7','8','9']
st_res=""
for ch in s:
 if ch not in l:
  st_res+=ch

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

You should not parse XML using tools like sed, or awk. It's error-prone.

If input changes, and before name parameter you will get new-line character instead of space it will fail some day producing unexpected results.

If you are really sure, that your input will be always formated this way, you can use cut. It's faster than sed and awk:

cut -d'"' -f2 < input.txt

It will be better to first parse it, and extract only parameter name attribute:

xpath -q -e //@name input.txt | cut -d'"' -f2

To learn more about xpath, see this tutorial: http://www.w3schools.com/xpath/

For people like me want the long date format (LLLL) but without the time of day, there's a GitHub issue for that: https://github.com/moment/moment/issues/2505. For now, there's a workaround:

var localeData = moment.localeData( moment.locale() ),
    llll = localeData.longDateFormat( 'llll' ),
    lll = localeData.longDateFormat( 'lll' ),
    ll = localeData.longDateFormat( 'll' ),
    longDateFormat = llll.replace( lll.replace( ll, '' ), '' );
var formattedDate = myMoment.format(longDateFormat);

Having been bitten by this, I have a habit of including locally defined variables in the innermost scope which I use to transfer to any closure. In your example:

foreach (var s in strings)
    query = query.Where(i => i.Prop == s); // access to modified closure

I do:

foreach (var s in strings)
{
    string search = s;
    query = query.Where(i => i.Prop == search); // New definition ensures unique per iteration.
}        

Once you have that habit, you can avoid it in the very rare case you actually intended to bind to the outer scopes. To be honest, I don't think I have ever done so.

I didn't understand how the accepted answer answers the actual question of how to run any commands on the server after sshpass is given from within the bash script file. For that reason, I'm providing an answer.

After your provided script commands, execute additional commands like below:

sshpass -p 'password' ssh user@host "ls; whois google.com;" #or whichever commands you would like to use, for multiple commands provide a semicolon ; after the command

In your script:

#! /bin/bash

sshpass -p 'password' ssh user@host "ls; whois google.com;"

Try this:

function funcName() {
    alert("test");
}

var run = setInterval(funcName, 10000)

simplified generic form,

int div_up(int n, int d) {
    return n / d + (((n < 0) ^ (d > 0)) && (n % d));
} //i.e. +1 iff (not exact int && positive result)

For a more generic answer, C++ functions for integer division with well defined rounding strategy

std::min_element(vec.begin(), vec.end()) - for std::vector
std::min_element(v, v+n) - for array
std::min_element( std::begin(v), std::end(v) ) - added C++11 version from comment by @JamesKanze

Export all databases in Ubuntu

1 - mysqldump -u root -p --databases database1 database2 > ~/Desktop/databases_1_2.sql

OR

2 - mysqldump -u root -p --all_databases > ~/Desktop/all_databases.sql

the secure way is encrypt your sensitive data by AES and the encryption key is derivation by password-based key derivation function (PBE), the master password used to encrypt/decrypt the encrypt key for AES.

master password -> secure key-> encrypt data by the key

You can use pbkdf2

from PBKDF2 import PBKDF2
from Crypto.Cipher import AES
import os
salt = os.urandom(8)    # 64-bit salt
key = PBKDF2("This passphrase is a secret.", salt).read(32) # 256-bit key
iv = os.urandom(16)     # 128-bit IV
cipher = AES.new(key, AES.MODE_CBC, iv)

make sure to store the salt/iv/passphrase , and decrypt using same salt/iv/passphase

Weblogic used similar approach to protect passwords in config files

You're not far; you need to do something like this:

[WebMethod]
public static string GetProducts()
{
  // instantiate a serializer
  JavaScriptSerializer TheSerializer = new JavaScriptSerializer();

  //optional: you can create your own custom converter
  TheSerializer.RegisterConverters(new JavaScriptConverter[] {new MyCustomJson()});

  var products = context.GetProducts().ToList();   

  var TheJson = TheSerializer.Serialize(products);

  return TheJson;
}

You can reduce this code further but I left it like that for clarity. In fact, you could even write this:

return context.GetProducts().ToList();

and this would return a json string. I prefer to be more explicit because I use custom converters. There's also Json.net but the framework's JavaScriptSerializer works just fine out of the box.

button {
    background:transparent;
    border:none;
    outline:none;
    display:block;
    height:200px;
    width:200px;
    cursor:pointer;
}

Give the height and width with respect to the image in the background.This removes the borders and color of a button.You might also need to position it absolute so you can correctly place it where you need.I cant help you further without posting you code

To make it truly invisible you have to set outline:none; otherwise there would be a blue outline in some browsers and you have to set display:block if you need to click it and set dimensions to it

Simply place this line in your Model:

public $timestamps = false;

And that's it!

Example:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Post extends Model
{
    public $timestamps = false;

    //
}

To disable timestamps for one operation (e.g. in a controller):

$post->content = 'Your content'; 
$post->timestamps = false; // Will not modify the timestamps on save
$post->save();

To disable timestamps for all of your Models, create a new BaseModel file:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class BaseModel extends Model
{
    public $timestamps = false;

    //
}

Then extend each one of your Models with the BaseModel, like so:

<?php

namespace App;

class Post extends BaseModel
{
    //
}

T(n) = 2T(n/2)+ c

T(n/2) = 2T(n/4) + c => T(n) = 4T(n/4) + 2c + c

similarly T(n) = 8T(n/8) + 4c+ 2c + c

....

....

last step ... T(n) = nT(1) + c(sum of powers of 2 from 0 to h(height of tree))

so Complexity is O(2^(h+1) -1)

but h = log(n)

so, O(2n - 1) = O(n)

The accepted answer is great. I wanted to look at what happens to the Angular scope in the context of ng-repeat. The thing is, Angular will create a sub-scope for each repeated item. When calling into a method defined on the original $scope, that retains its original value (due to javascript closure). However, the this refers the calling scope/object. This works out well, so long as you're clear on when $scope and this are the same and when they are different. hth

Here is a fiddle that illustrates the difference: https://jsfiddle.net/creitzel/oxsxjcyc/

I hope this is helpful, as well as easiest one.

 $("#form").submit(function (e) { 
    e.preventDefault();
    input_values =  $(this).serializeArray();
  });

Create an XML file named border.xml in the drawable folder and put the following code in it.

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list> 

Then add a background to your linear layout like this:

         android:background="@drawable/border"

EDIT :

This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:

ALSO

tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :

Finally its works perfectly with all APIs

EDIT 2 :

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:left="0dp" android:right="0dp"  android:top="0dp"  
        android:bottom="-10dp"> 
    <shape android:shape="rectangle">
     <stroke android:width="10dp" android:color="#B22222" />
    </shape>
   </item>  
 </layer-list> 

hope this help .

As I see it, there are two problems that need addressing when needing a default value.

1. You need the value present when a new object is initialized. Using after_initialize is not suitable because, as stated, it will be called during calls to #find which will lead to a performance hit.
2. You need to persist the default value when saved

Here is my solution:

# the reader providers a default if nil
# but this wont work when saved
def status
  read_attribute(:status) || "P"
end

# so, define a before_validation callback
before_validation :set_defaults
protected
def set_defaults
  # if a non-default status has been assigned, it will remain
  # if no value has been assigned, the reader will return the default and assign it
  # this keeps the default logic DRY
  status = status
end

I'd love to know why people think of this approach.

You can also use split and join:

"Sonic Free Games".split(" ").join("-").toLowerCase(); //sonic-free-games

(Get-Date (Get-Date -Format d)).AddHours(-2)

scroll.fullScroll(View.FOCUS_DOWN) will lead to the change of focus. That will bring some strange behavior when there are more than one focusable views, e.g two EditText. There is another way for this question.

    View lastChild = scrollLayout.getChildAt(scrollLayout.getChildCount() - 1);
    int bottom = lastChild.getBottom() + scrollLayout.getPaddingBottom();
    int sy = scrollLayout.getScrollY();
    int sh = scrollLayout.getHeight();
    int delta = bottom - (sy + sh);

    scrollLayout.smoothScrollBy(0, delta);

This works well.

Kotlin Extension

fun ScrollView.scrollToBottom() {
    val lastChild = getChildAt(childCount - 1)
    val bottom = lastChild.bottom + paddingBottom
    val delta = bottom - (scrollY+ height)        
    smoothScrollBy(0, delta)
}

On Debian (or Ubuntu) systems, just install libmysqlclient-dev package using:

sudo apt-get install libmysqlclient-dev

and then:

gem install mysql

It will be installed without any error.

Try this:

private byte[] Hex2Bin(string hex) 
{
 if ((hex == null) || (hex.Length < 1)) {
  return new byte[0];
 }
 int num = hex.Length / 2;
 byte[] buffer = new byte[num];
 num *= 2;
 for (int i = 0; i < num; i++) {
  int num3 = int.Parse(hex.Substring(i, 2), NumberStyles.HexNumber);
  buffer[i / 2] = (byte) num3;
  i++;
 }
 return buffer;
}

private string Bin2Hex(byte[] binary) 
{
 StringBuilder builder = new StringBuilder();
 foreach(byte num in binary) {
  if (num > 15) {
   builder.AppendFormat("{0:X}", num);
  } else {
   builder.AppendFormat("0{0:X}", num); /////// ?? 15 ???? 0
  }
 }
 return builder.ToString();
}

I had to do something similar for my users, with a small variant that they want to have a running number grouping the similar items. Thought I'd share it here.

• Make a new column A
• Assuming the first row of data is in row 2 (row 1 being header), put 1 in A2
• Assuming your File No is in column B, in the second row (in this case A3) make the formula =IF(B3=B2,A2,A2+1)
• Fill/copy-paste cell A3 down the column to the last row (be careful not to copy A2 by accident; that will populate all cells with 1)
• Select the data range
• In the Home ribbon select Conditional Formatting -> New Rule
• Choose Use a formula to determine which cells to format
• In the formula cell, put =MOD($A1, 2)=1 as the formula
• Click Format, select the Fill tab
• Select the Background Color you want, then click OK
• Click OK

In most browsers, you can use a javascript variable instead of using document.getElementById. Say your html body content is like this:

<section id="mySection"> Hello </section>

Then you can just refer to mySection as a variable in javascript:

mySection.innerText += ', world'
// same as: document.getElementById('mySection').innerText += ', world'

See this snippet:

mySection.innerText += ', world!'

<section id="mySection"> Hello </section>

You haven't been very specific with your code, so I'll make up a scenario. Let's say you have 10 ajax calls and you want to accumulate the results from those 10 ajax calls and then when they have all completed you want to do something. You can do it like this by accumulating the data in an array and keeping track of when the last one has finished:

Manual Counter

var ajaxCallsRemaining = 10;
var returnedData = [];

for (var i = 0; i < 10; i++) {
    doAjax(whatever, function(response) {
        // success handler from the ajax call

        // save response
        returnedData.push(response);

        // see if we're done with the last ajax call
        --ajaxCallsRemaining;
        if (ajaxCallsRemaining <= 0) {
            // all data is here now
            // look through the returnedData and do whatever processing 
            // you want on it right here
        }
    });
}

Note: error handling is important here (not shown because it's specific to how you're making your ajax calls). You will want to think about how you're going to handle the case when one ajax call never completes, either with an error or gets stuck for a long time or times out after a long time.

jQuery Promises

Adding to my answer in 2014. These days, promises are often used to solve this type of problem since jQuery's $.ajax() already returns a promise and $.when() will let you know when a group of promises are all resolved and will collect the return results for you:

var promises = [];
for (var i = 0; i < 10; i++) {
    promises.push($.ajax(...));
}
$.when.apply($, promises).then(function() {
    // returned data is in arguments[0][0], arguments[1][0], ... arguments[9][0]
    // you can process it here
}, function() {
    // error occurred
});

ES6 Standard Promises

As specified in kba's answer: if you have an environment with native promises built-in (modern browser or node.js or using babeljs transpile or using a promise polyfill), then you can use ES6-specified promises. See this table for browser support. Promises are supported in pretty much all current browsers, except IE.

If doAjax() returns a promise, then you can do this:

var promises = [];
for (var i = 0; i < 10; i++) {
    promises.push(doAjax(...));
}
Promise.all(promises).then(function() {
    // returned data is in arguments[0], arguments[1], ... arguments[n]
    // you can process it here
}, function(err) {
    // error occurred
});

If you need to make a non-promise async operation into one that returns a promise, you can "promisify" it like this:

function doAjax(...) {
    return new Promise(function(resolve, reject) {
        someAsyncOperation(..., function(err, result) {
            if (err) return reject(err);
            resolve(result);
        });
    });
}

And, then use the pattern above:

var promises = [];
for (var i = 0; i < 10; i++) {
    promises.push(doAjax(...));
}
Promise.all(promises).then(function() {
    // returned data is in arguments[0], arguments[1], ... arguments[n]
    // you can process it here
}, function(err) {
    // error occurred
});

Bluebird Promises

If you use a more feature rich library such as the Bluebird promise library, then it has some additional functions built in to make this easier:

 var doAjax = Promise.promisify(someAsync);
 var someData = [...]
 Promise.map(someData, doAjax).then(function(results) {
     // all ajax results here
 }, function(err) {
     // some error here
 });

In 5.2, you can use the request directly with:

$request->route()->getName();

or via the helper method:

request()->route()->getName();

Output example:

"home.index"

Now there is a very useful npm package for this: buffer https://github.com/feross/buffer

It tries to provide an API that is 100% identical to node's Buffer API and allow:

• convert typed array to buffer: https://github.com/feross/buffer#convert-typed-array-to-buffer
• convert buffer to typed array: https://github.com/feross/buffer#convert-buffer-to-typed-array

and few more.

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

Something that your code doesn't account for is displaying multiple errors. As you have noted above it is possible for the user to upload a file >2MB of the wrong type, but your code can only report one of the issues. Try something like:

if(isset($_FILES['uploaded_file'])) {
    $errors     = array();
    $maxsize    = 2097152;
    $acceptable = array(
        'application/pdf',
        'image/jpeg',
        'image/jpg',
        'image/gif',
        'image/png'
    );

    if(($_FILES['uploaded_file']['size'] >= $maxsize) || ($_FILES["uploaded_file"]["size"] == 0)) {
        $errors[] = 'File too large. File must be less than 2 megabytes.';
    }

    if((!in_array($_FILES['uploaded_file']['type'], $acceptable)) && (!empty($_FILES["uploaded_file"]["type"]))) {
        $errors[] = 'Invalid file type. Only PDF, JPG, GIF and PNG types are accepted.';
    }

    if(count($errors) === 0) {
        move_uploaded_file($_FILES['uploaded_file']['tmpname'], '/store/to/location.file');
    } else {
        foreach($errors as $error) {
            echo '<script>alert("'.$error.'");</script>';
        }

        die(); //Ensure no more processing is done
    }
}

Look into the docs for move_uploaded_file() (it's called move not store) for more.

You can use the Enum.TryParse method:

Age age;
if (Enum.TryParse<Age>("New_Born", out age))
{
    // You now have the value in age 
}

To my knowledge, only ENV allows that, as mentioned in "Environment replacement"

Environment variables (declared with the ENV statement) can also be used in certain instructions as variables to be interpreted by the Dockerfile.

They have to be environment variables in order to be redeclared in each new containers created for each line of the Dockerfile by docker build.

In other words, those variables aren't interpreted directly in a Dockerfile, but in a container created for a Dockerfile line, hence the use of environment variable.

This day, I use both ARG (docker 1.10+, and docker build --build-arg var=value) and ENV.
Using ARG alone means your variable is visible at build time, not at runtime.

My Dockerfile usually has:

ARG var
ENV var=${var}

In your case, ARG is enough: I use it typically for setting http_proxy variable, that docker build needs for accessing internet at build time.

I had the same problem. I googled it for two days. At last I accidentally noticed that the problem was access modifier of the constructor of the Controller. I didn’t put the public key word behind the Controller’s constructor.

public class MyController : ApiController
    {
        private readonly IMyClass _myClass;

        public MyController(IMyClass myClass)
        {
            _myClass = myClass;
        }
    }

I add this experience as another answer maybe someone else made a similar mistake.

Jaap van Hengstum's answer works great however I think it is expensive and if we apply this method on a Button for example, the touch effect is lost since the view is rendered as a bitmap.

For me the best method and the simplest one consists in applying a mask on the view, like that:

@Override
protected void onSizeChanged(int width, int height, int oldWidth, int oldHeight) {
    super.onSizeChanged(width, height, oldWidth, oldHeight);

    float cornerRadius = <whatever_you_want>;
    this.path = new Path();
    this.path.addRoundRect(new RectF(0, 0, width, height), cornerRadius, cornerRadius, Path.Direction.CW);
}

@Override
protected void dispatchDraw(Canvas canvas) {
    if (this.path != null) {
        canvas.clipPath(this.path);
    }
    super.dispatchDraw(canvas);
}

This could be a permission issue,

change the ownership,

sudo chown -v -R usr-name:group-name folder-name

Use like this.

List<String> stockList = new ArrayList<String>();
stockList.add("stock1");
stockList.add("stock2");

String[] stockArr = new String[stockList.size()];
stockArr = stockList.toArray(stockArr);

for(String s : stockArr)
    System.out.println(s);

I've also find this fix that zooms to fit all markers

LatLngList: an array of instances of latLng, for example:

// "map" is an instance of GMap3

var LatLngList = [
                     new google.maps.LatLng (52.537,-2.061), 
                     new google.maps.LatLng (52.564,-2.017)
                 ],
    latlngbounds = new google.maps.LatLngBounds();

LatLngList.forEach(function(latLng){
   latlngbounds.extend(latLng);
});

// or with ES6:
// for( var latLng of LatLngList)
//    latlngbounds.extend(latLng);

map.setCenter(latlngbounds.getCenter());
map.fitBounds(latlngbounds); 

I know this is an old post but this adaptation of My Mai's answer works nicely for me...

angular.module("app").directive("numbersOnly", function() {
  return {
    require: "ngModel",
    restrict: "A",
    link: function(scope, element, attr, ctrl) {
        function inputValue(val) {
            if (val) {
                //transform val to a string so replace works
                var myVal = val.toString();

                //replace any non numeric characters with nothing
                var digits = myVal.replace(/\D/g, "");

                //if anything needs replacing - do it!
                if (digits !== myVal) {
                    ctrl.$setViewValue(digits);
                    ctrl.$render();
                }
                return parseFloat(digits);
            }
            return undefined;
        }
        ctrl.$parsers.push(inputValue);
    }
  };
});

An RGB hex string is just a number from 0x0 through 0xFFFFFF, so simply generate a number in that range and convert it to hexadecimal:

function rand_color() {
    return '#' . str_pad(dechex(mt_rand(0, 0xFFFFFF)), 6, '0', STR_PAD_LEFT);
}

or:

function rand_color() {
    return sprintf('#%06X', mt_rand(0, 0xFFFFFF));
}

You can either go for f5 it will execute all the scrips on the tab.

Or

You can create a sql file and put all the insert statements in it and than give the file path in sql plus and execute.

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

Navbars may contain bits of text with the help of .navbar-text. This class adjusts vertical alignment and horizontal spacing for strings of text.

i applied the .navbar-text class to my <li> element, so the result is

<li class="nav-item navbar-text">

this centers the links vertically with respect to my navbar-brand img

Either $objPage is not an instance variable OR your are overwriting $objPage with something that is not an instance of class PageAttributes.

• The first part consists of creating a new package under java folder and selecting then dragging all your source files from the old package to this new package. After that you need to remane the package name in android manifest to the name of the new package.

• In step 2, here is what you need to do.You need to change the old package name in applicationId under the module build.gradle in your android studio in addition to changing the package name in the manifest. So in summary, click on build.gradle which is below the "AndroidManifest.xml" and modify the value of applicationId to your new package name.

• Then, at the very top, under build. clean your project, then rebuild. It should be fine from here.

import base64
from PIL import Image
from io import BytesIO

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

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

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

For me this problem arised while trying to connect to the SAP Hana database. When I got this error,

OperationalError: Lost connection to HANA server (ConnectionResetError(10054, 'An existing connection was forcibly closed by the remote host', None, 10054, None))

I tried to run the code for connection(mentioned below), which created that error, again and it worked.

    import pyhdb
    connection = pyhdb.connect(host="example.com",port=30015,user="user",password="secret")
    cursor = connection.cursor()
    cursor.execute("SELECT 'Hello Python World' FROM DUMMY")
    cursor.fetchone()
    connection.close()

It was because the server refused to connect. It might require you to wait for a while and try again. Try closing the Hana Studio by logging off and then logging in again. Keep running the code for a number of times.

If you have a project ready and just want to change some code and then build. Check out MSBuild which is located in the Microsoft.Net under windows directory.

Maven version 3.2.1 added this feature, you can use the -pl switch (shortcut for --projects list) with ! or - (source) to exclude certain submodules.

mvn -pl '!submodule-to-exclude' install
mvn -pl -submodule-to-exclude install

Be careful in bash the character ! is a special character, so you either have to single quote it (like I did) or escape it with the backslash character.

The syntax to exclude multiple module is the same as the inclusion

mvn -pl '!submodule1,!submodule2' install
mvn -pl -submodule1,-submodule2 install

EDIT Windows does not seem to like the single quotes, but it is necessary in bash ; in Windows, use double quotes (thanks @awilkinson)

mvn -pl "!submodule1,!submodule2" install

# value  value to be truncated
# n  number of values after decimal

value = 0.999782
n = 3
float(int(value*1en))*1e-n

You could use the GO command. That will restart the execution of SQL statements after an error. In my case I have a few 1000 INSERT statements, where a handful of those records already exist in the database, I just don't know which ones. I found that after processing a few 100, execution just stops with an error message that it can't INSERT as the record already exists. Quite annoying, but putting a GO solved this. It may not be the fastest solution, but speed was not my problem.

GO
INSERT INTO mytable (C1,C2,C3) VALUES(1,2,3)
GO
INSERT INTO mytable (C1,C2,C3) VALUES(4,5,6)
 etc ...

You can do following:

#!/bin/bash
cd /your/project/directory
# start another shell and replacing the current
exec /bin/bash

EDIT: This could be 'dotted' as well, to prevent creation of subsequent shells.

Example:

. ./previous_script  (with or without the first line)

XML Schemas describe hierarchial data models and may not map well to a relational data model. Mapping XSD's to database tables is very similar mapping objects to database tables, in fact you could use a framework like Castor that does both, it allows you to take a XML schema and generate classes, database tables, and data access code. I suppose there are now many tools that do the same thing, but there will be a learning curve and the default mappings will most like not be what you want, so you have to spend time customizing whatever tool you use.

XSLT might be the fastest way to generate exactly the code that you want. If it is a small schema hardcoding it might be faster than evaluating and learing a bunch of new technologies.

Just to improve YCR's answer:

1) I added black lines on x and y axis. Otherwise they are made transparent too.

2) I added a transparent theme to the legend key. Otherwise, you will get a fill there, which won't be very esthetic.

Finally, note that all those work only with pdf and png formats. jpeg fails to produce transparent graphs.

MyTheme_transparent <- theme(
    panel.background = element_rect(fill = "transparent"), # bg of the panel
    plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
    panel.grid.major = element_blank(), # get rid of major grid
    panel.grid.minor = element_blank(), # get rid of minor grid
    legend.background = element_rect(fill = "transparent"), # get rid of legend bg
    legend.box.background = element_rect(fill = "transparent"), # get rid of legend panel bg
    legend.key = element_rect(fill = "transparent", colour = NA), # get rid of key legend fill, and of the surrounding
    axis.line = element_line(colour = "black") # adding a black line for x and y axis
)

To delete a database even if it's running, you can use this batch file

@echo off

set /p dbName= "Enter your database name to drop: " 

echo Setting to single-user mode
sqlcmd -Q "ALTER DATABASE [%dbName%] SET  SINGLE_USER WITH ROLLBACK IMMEDIATE"

echo Dropping...
sqlcmd -Q "drop database %dbName%"

echo Completed.

pause

You need to use the target selector.

Here is a fiddle with another example: http://jsfiddle.net/YYPKM/3/

As of CMake 3.1+ the developers strongly discourage users from using file(GLOB or file(GLOB_RECURSE to collect lists of source files.

Note: We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.

See the documentation here.

There are two goods answers ([1], [2]) here on SO detailing the reasons to manually list source files.

It is possible. E.g. with file(GLOB:

cmake_minimum_required(VERSION 2.8)

file(GLOB helloworld_SRC
     "*.h"
     "*.cpp"
)

add_executable(helloworld ${helloworld_SRC})

Note that this requires manual re-running of cmake if a source file is added or removed, since the generated build system does not know when to ask CMake to regenerate, and doing it at every build would increase the build time.

As of CMake 3.12, you can pass the CONFIGURE_DEPENDS flag to file(GLOB to automatically check and reset the file lists any time the build is invoked. You would write:

cmake_minimum_required(VERSION 3.12)

file(GLOB helloworld_SRC CONFIGURE_DEPENDS "*.h" "*.cpp")

This at least lets you avoid manually re-running CMake every time a file is added.

int[] and int* are represented the same way, except int[] allocates (IIRC).

ap is a pointer, therefore giving it the value of an integer is dangerous, as you have no idea what's at address 45.

when you try to access it (x = *ap), you try to access address 45, which causes the crash, as it probably is not a part of the memory you can access.

The easiest way to do is export your database to .sql, open it on Notepad++ and "Search and Replace" the utf8mb4_unicode_ci to utf8_unicode_ci and also replace utf8mb4 to utf8. Also don't forget to change the database collation to utf8_unicode_ci (Operations > Collation).

I had the same issue which was fixed following the instructions below

If you can use project configurations in all your environments, that would make defining a 64- and 32-bit symbol easy. So you'd have project configurations like this:

32-bit Debug
32-bit Release
64-bit Debug
64-bit Release

EDIT: These are generic configurations, not targetted configurations. Call them whatever you want.

If you can't do that, I like Jared's idea.

*Make sure you update your linux box first

yum update

In case someone still has this problem, this is a valid solution:

centos-release : rpm -q centos-release

Centos 6.*

wget http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
rpm -ivh epel-release-6-8.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
rpm -Uvh remi-release-6*.rpm

Centos 5.*

wget http://ftp.jaist.ac.jp/pub/Linux/Fedora/epel/5/x86_64/epel-release-5-4.noarch.rpm
rpm -ivh epel-release-5-4.noarch.rpm
wget http://rpms.famillecollet.com/enterprise/remi-release-5.rpm
rpm -Uvh remi-release-5*.rpm

Then just do this to update:

yum --enablerepo=remi upgrade php-mbstring

Or this to install:

yum --enablerepo=remi install php-mbstring

My solution based on Mahdi Hijazi answer, but without any custom views:

Layout:

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

    <ScrollView 
        android:id="@+id/scrollVertical"
        android:layout_width="wrap_content"
        android:layout_height="match_parent" >

        <WateverViewYouWant/>

    </ScrollView>
</HorizontalScrollView>

Code (onCreate/onCreateView):

    final HorizontalScrollView hScroll = (HorizontalScrollView) value.findViewById(R.id.scrollHorizontal);
    final ScrollView vScroll = (ScrollView) value.findViewById(R.id.scrollVertical);
    vScroll.setOnTouchListener(new View.OnTouchListener() { //inner scroll listener         
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            return false;
        }
    });
    hScroll.setOnTouchListener(new View.OnTouchListener() { //outer scroll listener         
        private float mx, my, curX, curY;
        private boolean started = false;

        @Override
        public boolean onTouch(View v, MotionEvent event) {
            curX = event.getX();
            curY = event.getY();
            int dx = (int) (mx - curX);
            int dy = (int) (my - curY);
            switch (event.getAction()) {
                case MotionEvent.ACTION_MOVE:
                    if (started) {
                        vScroll.scrollBy(0, dy);
                        hScroll.scrollBy(dx, 0);
                    } else {
                        started = true;
                    }
                    mx = curX;
                    my = curY;
                    break;
                case MotionEvent.ACTION_UP: 
                    vScroll.scrollBy(0, dy);
                    hScroll.scrollBy(dx, 0);
                    started = false;
                    break;
            }
            return true;
        }
    });

You can change the order of the scrollviews. Just change their order in layout and in the code. And obviously instead of WateverViewYouWant you put the layout/views you want to scroll both directions.

Select your results by clicking in the top left corner, right click and select "Copy with Headers". Paste in excel. Done!

In stead of "live" you need to use "on" event, but assign it to the document object:

Use:

$(document).on('hidden.bs.modal', '#Control_id', function (event) {
// code to run on closing
});

As all html ids are unique in a valid html document why not search for the ID directly? If you're concerned if they type in an id that isn't a table then you can inspect the tag type that way?

Just an idea!

To make sure it's a simulator issue, see if you can connect to the simulator with a brand new project without changing any code. Try the tab bar template.

If you think it's a simulator issue, press the iOS Simulator menu. Select "Reset Content and Settings...". Press "Reset."

I can't see your XIB and what @properties you have connected in Interface Builder, but it could also be that you're not loading your window, or that your window is not loading your view controller.

In the top level of the IIS Manager (above Sites), you should see the Application Pools tree node. Right click on "Application Pools", choose "Add Application Pool".

Give it a name, choose .NET Framework 4.0 and either Integrated or Classic mode.

When you add or edit a web site, your new application pools will now show up in the list.

you can use SS_ISCONNECTED macro in getsockopt() function. SS_ISCONNECTED is define in socketvar.h.

I found the best way: I always check the latest branch created by this way

Just in case someone stumbles upon this like I did and doesn't realise, the two variations above are for different use cases.

The following:

.blue-border, .background {
    border: 1px solid #00f;
    background: #fff;
}

is for when you want to add styles to elements that have either the blue-border or background class, for example:

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

would all get a blue border and white background applied to them.

However, the accepted answer is different.

.blue-border.background {
    border: 1px solid #00f;
    background: #fff;
}

This applies the styles to elements that have both classes so in this example only the <div> with both classes should get the styles applied (in browsers that interpret the CSS properly):

<div class="blue-border">Hello</div>
<div class="background">World</div>
<div class="blue-border background">!</div>

So basically think of it like this, comma separating applies to elements with one class OR another class and dot separating applies to elements with one class AND another class.

I got the same issue and this solved it for me. Perhaps this might be a fix for your problem too.

Here is the fix. Follow this link http://www.anindya.com/php-5-4-3-and-php-5-3-13-x64-64-bit-for-windows/

Go to "Fixed curl extensions" and download the extension that matches your PHP version.

Extract and copy "php_curl.dll" to the extension directory of your wamp installation. (i.e. C:\wamp\bin\php\php5.3.13\ext)

Restart Apache

Done!

After reading the other answers, I still had trouble understanding why the set comes out un-ordered.

Mentioned this to my partner and he came up with this metaphor: take marbles. You put them in a tube a tad wider than marble width : you have a list. A set, however, is a bag. Even though you feed the marbles one-by-one into the bag; when you pour them from a bag back into the tube, they will not be in the same order (because they got all mixed up in a bag).

The issue here is that input() returns a string in Python 3.x, so when you do your comparison, you are comparing a string and an integer, which isn't well defined (what if the string is a word, how does one compare a string and a number?) - in this case Python doesn't guess, it throws an error.

To fix this, simply call int() to convert your string to an integer:

int(input(...))

As a note, if you want to deal with decimal numbers, you will want to use one of float() or decimal.Decimal() (depending on your accuracy and speed needs).

Note that the more pythonic way of looping over a series of numbers (as opposed to a while loop and counting) is to use range(). For example:

def main():
    print("Let me Retire Financial Calculator")
    deposit = float(input("Please input annual deposit in dollars: $"))
    rate = int(input ("Please input annual rate in percentage: %")) / 100
    time = int(input("How many years until retirement?"))
    value = 0
    for x in range(1, time+1):
        value = (value * rate) + deposit
        print("The value of your account after" + str(x) + "years will be $" + str(value))

1. Java code "BlockingQueue" which has synchronized put and get method.
2. Java code "Producer" , producer thread to produce data.
3. Java code "Consumer" , consumer thread to consume the data produced.
4. Java code "ProducerConsumer_Main", main function to start the producer and consumer thread.

    boolean available = false;

    public synchronized void put(int value) 
    {
        while (available == true)
        {
            try 
            {
                wait();
            } catch (InterruptedException e) {

        }

        item = value;

The OSIV Anti-Pattern

Instead of letting the business layer decide how it’s best to fetch all the associations that are needed by the View layer, OSIV (Open Session in View) forces the Persistence Context to stay open so that the View layer can trigger the Proxy initialization, as illustrated by the following diagram.

• The OpenSessionInViewFilter calls the openSession method of the underlying SessionFactory and obtains a new Session.
• The Session is bound to the TransactionSynchronizationManager.
• The OpenSessionInViewFilter calls the doFilter of the javax.servlet.FilterChain object reference and the request is further processed
• The DispatcherServlet is called, and it routes the HTTP request to the underlying PostController.
• The PostController calls the PostService to get a list of Post entities.
• The PostService opens a new transaction, and the HibernateTransactionManager reuses the same Session that was opened by the OpenSessionInViewFilter.
• The PostDAO fetches the list of Post entities without initializing any lazy association.
• The PostService commits the underlying transaction, but the Session is not closed because it was opened externally.
• The DispatcherServlet starts rendering the UI, which, in turn, navigates the lazy associations and triggers their initialization.
• The OpenSessionInViewFilter can close the Session, and the underlying database connection is released as well.

At first glance, this might not look like a terrible thing to do, but, once you view it from a database perspective, a series of flaws start to become more obvious.

The service layer opens and closes a database transaction, but afterward, there is no explicit transaction going on. For this reason, every additional statement issued from the UI rendering phase is executed in auto-commit mode. Auto-commit puts pressure on the database server because each transaction issues a commit at end, which can trigger a transaction log flush to disk. One optimization would be to mark the Connection as read-only which would allow the database server to avoid writing to the transaction log.

There is no separation of concerns anymore because statements are generated both by the service layer and by the UI rendering process. Writing integration tests that assert the number of statements being generated requires going through all layers (web, service, DAO) while having the application deployed on a web container. Even when using an in-memory database (e.g. HSQLDB) and a lightweight webserver (e.g. Jetty), these integration tests are going to be slower to execute than if layers were separated and the back-end integration tests used the database, while the front-end integration tests were mocking the service layer altogether.

The UI layer is limited to navigating associations which can, in turn, trigger N+1 query problems. Although Hibernate offers @BatchSize for fetching associations in batches, and FetchMode.SUBSELECT to cope with this scenario, the annotations are affecting the default fetch plan, so they get applied to every business use case. For this reason, a data access layer query is much more suitable because it can be tailored to the current use case data fetch requirements.

Last but not least, the database connection is held throughout the UI rendering phase which increases connection lease time and limits the overall transaction throughput due to congestion on the database connection pool. The more the connection is held, the more other concurrent requests are going to wait to get a connection from the pool.

Spring Boot and OSIV

Unfortunately, OSIV (Open Session in View) is enabled by default in Spring Boot, and OSIV is really a bad idea from a performance and scalability perspective.

So, make sure that in the application.properties configuration file, you have the following entry:

spring.jpa.open-in-view=false

This will disable OSIV so that you can handle the LazyInitializationException the right way.

Starting with version 2.0, Spring Boot issues a warning when OSIV is enabled by default, so you can discover this problem long before it affects a production system.

You need to use an Angular form directive on the select. You can do that with ngModel. For example

@Component({
  selector: 'my-app',
  template: `
    <h2>Select demo</h2>
    <select [(ngModel)]="selectedCity" (ngModelChange)="onChange($event)" >
      <option *ngFor="let c of cities" [ngValue]="c"> {{c.name}} </option>
    </select>
  `
})
class App {
  cities = [{'name': 'SF'}, {'name': 'NYC'}, {'name': 'Buffalo'}];
  selectedCity = this.cities[1];

  onChange(city) {
    alert(city.name);
  }
}

The (ngModelChange) event listener emits events when the selected value changes. This is where you can hookup your callback.

Note you will need to make sure you have imported the FormsModule into the application.

Here is a Plunker

I've run into the same issue and here is what I have discovered so far:

Pay attention to the last line - "This file can not be included by a module that also includes WINSOCK.H"

Adding comment for anyone using Plesk having issues with any of the above as it was driving me crazy, setting session.gc_maxlifetime from your PHP script wont work as Plesk has it's own garbage collection script run from cron.

I used the solution posted on the link below of moving the cron job from hourly to daily to avoid this issue, then the top answer above should work:

You mention Haxe/NME but you seem to instinctively dislike it. However, my experience with it has been very positive. Sure, the API is a reimplementation of the Flash API, but you're not limited to targeting Flash, you can also compile to HTML5 or native Windows, Mac, iOS and Android apps. Haxe is a pleasant, modern language similar to Java or C#.

If you're interested, I've written a bit about my experience using Haxe/NME: link

Suppose I have numbers 1 to 10 in cells A2:A11 with my autofilter in A1. I now filter to only show numbers greater then 5 (i.e. 6, 7, 8, 9, 10).

This code will only print visible cells:

Sub SpecialLoop()
    Dim cl As Range, rng As Range

    Set rng = Range("A2:A11")

    For Each cl In rng
        If cl.EntireRow.Hidden = False Then //Use Hidden property to check if filtered or not
            Debug.Print cl
        End If
    Next

End Sub

Perhaps there is a better way with SpecialCells but the above worked for me in Excel 2003.

EDIT

Just found a better way with SpecialCells:

Sub SpecialLoop()
    Dim cl As Range, rng As Range

    Set rng = Range("A2:A11")

    For Each cl In rng.SpecialCells(xlCellTypeVisible)
        Debug.Print cl
    Next cl

End Sub

To align one flex child to the right set it withmargin-left: auto;

From the flex spec:

One use of auto margins in the main axis is to separate flex items into distinct "groups". The following example shows how to use this to reproduce a common UI pattern - a single bar of actions with some aligned on the left and others aligned on the right.

.wrap div:last-child {
  margin-left: auto;
}

Updated fiddle

.wrap {_x000D_
  display: flex;_x000D_

Note:

You could achieve a similar effect by setting flex-grow:1 on the middle flex item (or shorthand flex:1) which would push the last item all the way to the right. (Demo)

The obvious difference however is that the middle item becomes bigger than it may need to be. Add a border to the flex items to see the difference.

You need MouseClick instead of Click event handler, reference.

switch (e.Button) {

    case MouseButtons.Left:
    // Left click
    break;

    case MouseButtons.Right:
    // Right click
    break;
    ...
}

According to your comments, you're sending a JavaScript file anyway. Do the rollover in JavaScript. jQuery's $.hover() method makes it easy, as does every other JavaScript wrapper. It's not too hard in straight JavaScript either.

If you're willing to use underscore or lodash, you can use pick (or its opposite, omit).

Examples from underscore's docs:

_.pick({name: 'moe', age: 50, userid: 'moe1'}, 'name', 'age');
// {name: 'moe', age: 50}

Or with a callback (for lodash, use pickBy):

_.pick({name: 'moe', age: 50, userid: 'moe1'}, function(value, key, object) {
  return _.isNumber(value);
});
// {age: 50}

SELECT
    hat,
    shoe,
    boat,
    0 as placeholder
FROM
    objects

And '' as placeholder for strings.

It is discouraged and problematic yet doable. What you need is a custom URI scheme ie. You need to register and configure it on your machine and then hook an url with that scheme to the button.

URI scheme is the part before :// in an URI. Standard URI schemes are for example https or ftp or file. But there are custom like fx. mongodb. What you need is your own e.g. mypythonscript. It can be configured to exec the script or even just python with the script name in the params etc. It is of course a tradeoff between flexibility and security.

EDIT: Added more details about what an custom scheme is.

1. Use a good text editor like VS Code and open your .zshrc file (should be in your home directory. if you don't see it, be sure to right-click in the file folder when opening and choose option to 'show hidden files').

2. find where it states: export PATH=a-bunch-of-paths-separated-by-colons:

3. insert this at the end of the line, before the end-quote: :$HOME/.local/bin

And it should work for you.

You can test if this will work first by typing this in your terminal first: export PATH=$HOME/.local/bin:$PATH

If the error disappears after you type this into the terminal and your terminal functions normally, the above solution will work. If it doesn't, you'll have to find the folder where your reference error is located (the thing not found), and replace the PATH above with the PATH-TO-THAT-FOLDER.

To solve the problem with MySQL Workbench (After applying the solution on the server side) :

Remove SQL_MODE to TRADITIONAL in the preferences panel.

You could embed the '' default in your regex by adding |$:

>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''

Also works with re.search pointed out by others:

>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''

What about checking of indexes?

        numbers.stream()
            .filter(integer -> numbers.indexOf(integer) != numbers.lastIndexOf(integer))
            .collect(Collectors.toSet())
            .forEach(System.out::println);

Here's a simpler solution but with no extra surrounding div:

<input type="submit" value="Submit">

The CSS uses a basic image replacement technique. For bonus points, it shows using an image sprite:

<style>
    input[type="submit"] {
        border: 0;
        background: url('sprite.png') no-repeat -40px left;
        text-indent: -9999em;
        line-height:3000;
        width: 50px;
        height: 20px;
    }
</style>

for what DB is the user? look at this example

mysql> create database databasename;
Query OK, 1 row affected (0.00 sec)
mysql> grant all on databasename.* to cmsuser@localhost identified by 'password';
Query OK, 0 rows affected (0.00 sec)
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

so to return to you question the "%" operator means all computers in your network.

like aspesa shows I'm also sure that you have to create or update a user. look for all your mysql users:

SELECT user,password,host FROM user;

as soon as you got your user set up you should be able to connect like this:

mysql -h localhost -u gmeier -p

hope it helps

Easiest way do this is to remove filter, fill series from top of total data. Filter your desired data back in, copy list of numbers into a new sheet (this should be only the total lines you want to add numbering to) paste into column A1. Add "1" into column B1, right click and hold then drag down to end of numbers and choose "fill series". Now return to your list with filters and in the next column to the right "VLOOKUP" the filtered number against the list you pasted into a new sheet and return the 2nd value.

Limit length based on words

Try this one, if you want to truncate based on Words instead of characters while also allowing an option to see the complete text.

Came here searching for a Read More solution based on words, sharing the custom Pipe i ended up writing.

Pipe:

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'readMore'
})
export class ReadMorePipe implements PipeTransform {

  transform(text: any, length: number = 20, showAll: boolean = false, suffix: string = '...'): any {
    
    if (showAll) {
      return text;
    }

    if ( text.split(" ").length > length ) {
      
      return text.split(" ").splice(0, length).join(" ") + suffix;
    }

    return text;
  }

}

In Template:

<p [innerHTML]="description | readMore:30:showAll"></p>
<button (click)="triggerReadMore()" *ngIf="!showAll">Read More<button>

Component:

export class ExamplePage implements OnInit {

    public showAll: any = false;
    
    triggerReadMore() {
        this.showAll = true;
    }
    
}

In Module:

import { ReadMorePipe } from '../_helpers/read-more.pipe';

@NgModule({
  declarations: [ReadMorePipe]
})
export class ExamplePageModule {}

Here's a way you can do it asynchronously and manage things like you would normally. Everything is still shared. You get a reference to the object that you want updated. Whenever you update that in your service, it gets updated globally without having to watch or return a promise. This is really nice because you can update the underlying object from within the service without ever having to rebind. Using Angular the way it's meant to be used. I think it's probably a bad idea to make $http.get/post synchronous. You'll get a noticeable delay in the script.

app.factory('AssessmentSettingsService', ['$http', function($http) {
    //assessment is what I want to keep updating
    var settings = { assessment: null };

    return {
        getSettings: function () {
             //return settings so I can keep updating assessment and the
             //reference to settings will stay in tact
             return settings;
        },
        updateAssessment: function () {
            $http.get('/assessment/api/get/' + scan.assessmentId).success(function(response) {
                //I don't have to return a thing.  I just set the object.
                settings.assessment = response;
            });
        }
    };
}]);

    ...
        controller: ['$scope', '$http', 'AssessmentSettingsService', function ($scope, as) {
            $scope.settings = as.getSettings();
            //Look.  I can even update after I've already grabbed the object
            as.updateAssessment();

And somewhere in a view:

<h1>{{settings.assessment.title}}</h1>

I have not used Recyclerview but I did it on ListView. Sample code in Recyclerview:

setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
        rowPos = mLayoutManager.findFirstVisibleItemPosition();

It is the listener when user is scrolling. The performance overhead is not significant. And the first visible position is accurate this way.

I don't like casting primitives, who knows what may happen.

Why do you have an irrational fear of casting primitives? Nothing bad will happen when you cast an int to a double. If you're just not sure of how it works, look it up in the Java Language Specification. Casting an int to double is a widening primitive conversion.

You can get rid of the extra pair of parentheses by casting the denominator instead of the numerator:

double d = num / (double) denom;

Usually a simple hash function works by taking the "component parts" of the input (characters in the case of a string), and multiplying them by the powers of some constant, and adding them together in some integer type. So for example a typical (although not especially good) hash of a string might be:

(first char) + k * (second char) + k^2 * (third char) + ...

Then if a bunch of strings all having the same first char are fed in, then the results will all be the same modulo k, at least until the integer type overflows.

[As an example, Java's string hashCode is eerily similar to this - it does the characters reverse order, with k=31. So you get striking relationships modulo 31 between strings that end the same way, and striking relationships modulo 2^32 between strings that are the same except near the end. This doesn't seriously mess up hashtable behaviour.]

A hashtable works by taking the modulus of the hash over the number of buckets.

It's important in a hashtable not to produce collisions for likely cases, since collisions reduce the efficiency of the hashtable.

Now, suppose someone puts a whole bunch of values into a hashtable that have some relationship between the items, like all having the same first character. This is a fairly predictable usage pattern, I'd say, so we don't want it to produce too many collisions.

It turns out that "because of the nature of maths", if the constant used in the hash, and the number of buckets, are coprime, then collisions are minimised in some common cases. If they are not coprime, then there are some fairly simple relationships between inputs for which collisions are not minimised. All the hashes come out equal modulo the common factor, which means they'll all fall into the 1/n th of the buckets which have that value modulo the common factor. You get n times as many collisions, where n is the common factor. Since n is at least 2, I'd say it's unacceptable for a fairly simple use case to generate at least twice as many collisions as normal. If some user is going to break our distribution into buckets, we want it to be a freak accident, not some simple predictable usage.

Now, hashtable implementations obviously have no control over the items put into them. They can't prevent them being related. So the thing to do is to ensure that the constant and the bucket counts are coprime. That way you aren't relying on the "last" component alone to determine the modulus of the bucket with respect to some small common factor. As far as I know they don't have to be prime to achieve this, just coprime.

But if the hash function and the hashtable are written independently, then the hashtable doesn't know how the hash function works. It might be using a constant with small factors. If you're lucky it might work completely differently and be nonlinear. If the hash is good enough, then any bucket count is just fine. But a paranoid hashtable can't assume a good hash function, so should use a prime number of buckets. Similarly a paranoid hash function should use a largeish prime constant, to reduce the chance that someone uses a number of buckets which happens to have a common factor with the constant.

In practice, I think it's fairly normal to use a power of 2 as the number of buckets. This is convenient and saves having to search around or pre-select a prime number of the right magnitude. So you rely on the hash function not to use even multipliers, which is generally a safe assumption. But you can still get occasional bad hashing behaviours based on hash functions like the one above, and prime bucket count could help further.

Putting about the principle that "everything has to be prime" is as far as I know a sufficient but not a necessary condition for good distribution over hashtables. It allows everybody to interoperate without needing to assume that the others have followed the same rule.

[Edit: there's another, more specialized reason to use a prime number of buckets, which is if you handle collisions with linear probing. Then you calculate a stride from the hashcode, and if that stride comes out to be a factor of the bucket count then you can only do (bucket_count / stride) probes before you're back where you started. The case you most want to avoid is stride = 0, of course, which must be special-cased, but to avoid also special-casing bucket_count / stride equal to a small integer, you can just make the bucket_count prime and not care what the stride is provided it isn't 0.]

I had exactly same problem but my fix was different - my company is encrypting all the files on my machines. After decrypting the file MSSQL did not have any issues to accessing and created the DB. Just right click .bak file -> Properties -> Advanced... -> Encrypt contents to secure data.

You could give it a try. The problem is that Windows inserts a carriage return as well as a line feed when given a new line. Unix-systems just insert a line feed. So the extra carriage return character could be the reason why your eclipse messes up with the newlines.

Grab one or two files from your project and convert them. You could use Notepad++ to do so. Just open the file, go to Format->Convert to Unix (when you are using windows).

In Linux just try this on a command line:

sed 's/$'"/`echo \\\r`/" yourfile.java > output.java

    for f in os.listdir(top):

        mode = os.stat(pathname)[ST_MODE]
        if S_ISDIR(mode):
            # It's a directory, recurse into it
            walktree(pathname, callback)
        elif S_ISREG(mode):
            # It's a file, call the callback function
            callback(pathname)
        else:

NPM is a package manager, you can install node.js packages using NPM

NPX is a tool to execute node.js packages.

It doesn't matter whether you installed that package globally or locally. NPX will temporarily install it and run it. NPM also can run packages if you configure a package.json file and include it in the script section.

So remember this, if you want to check/run a node package quickly without installing locally or globally use NPX.

npM - Manager

npX - Execute - easy to remember

The following example creates a file chooser and displays it as first an open-file dialog and then as a save-file dialog:

String filename = File.separator+"tmp";
JFileChooser fc = new JFileChooser(new File(filename));

// Show open dialog; this method does not return until the dialog is closed
fc.showOpenDialog(frame);
File selFile = fc.getSelectedFile();

// Show save dialog; this method does not return until the dialog is closed
fc.showSaveDialog(frame);
selFile = fc.getSelectedFile();

Here is a more elaborate example that creates two buttons that create and show file chooser dialogs.

// This action creates and shows a modal open-file dialog.
public class OpenFileAction extends AbstractAction {
    JFrame frame;
    JFileChooser chooser;

    OpenFileAction(JFrame frame, JFileChooser chooser) {
        super("Open...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showOpenDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

// This action creates and shows a modal save-file dialog.
public class SaveFileAction extends AbstractAction {
    JFileChooser chooser;
    JFrame frame;

    SaveFileAction(JFrame frame, JFileChooser chooser) {
        super("Save As...");
        this.chooser = chooser;
        this.frame = frame;
    }

    public void actionPerformed(ActionEvent evt) {
        // Show dialog; this method does not return until dialog is closed
        chooser.showSaveDialog(frame);

        // Get the selected file
        File file = chooser.getSelectedFile();
    }
};

To highlight a block of code in Notepad++, please do the following steps

1. Select the required text.
2. Right click to display the context menu
3. Choose Style token and select any of the five choices available ( styles from Using 1st style to using 5th style). Each is of different colors.If you want yellow color choose using 3rd style.

If you want to create your own style you can use Style Configurator under Settings menu.

When you are sending an e-mail through a server that requires SMTP Auth, you really need to specify it, and set the host, username and password (and maybe the port if it is not the default one - 25).

For example, I usually use PHPMailer with similar settings to this ones:

$mail = new PHPMailer();

// Settings
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';

$mail->Host       = "mail.example.com"; // SMTP server example
$mail->SMTPDebug  = 0;                     // enables SMTP debug information (for testing)
$mail->SMTPAuth   = true;                  // enable SMTP authentication
$mail->Port       = 25;                    // set the SMTP port for the GMAIL server
$mail->Username   = "username"; // SMTP account username example
$mail->Password   = "password";        // SMTP account password example

// Content
$mail->isHTML(true);                                  // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body    = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';

$mail->send();

Use the bootstrap classes col-xx-# and col-xx-offset-#

So what is happening here is your screen is getting divided into 12 columns. In col-xx-#, # is the number of columns you cover and offset is the number of columns you leave.

For xx, in a general website, md is preferred and if you want your layout to look the same in a mobile device, xs is preferred.

With what I can make of your requirement,

<div class="row">
  <div class="col-md-4">First Div</div>
  <div class="col-md-8">Second DIV </div>
</div>

Should do the trick.

I created a framework using Swift3/Xcode 8.1 and was consuming it in an Objective-C/Xcode 8.1 project. To fix this issue I had to enable Always Embed Swift Standard Libraries option under Build Options.

Have a look at this screenshot:

The best way is to extract the current year then use concatenation like this :

SELECT CONCAT(year(now()), '-01-01') as start, -- fist day of current year
       CONCAT(year(now()), '-31-12') as end;   -- last day of current year

That gives you : start : 2020-01-01 and end : 2020-31-12 in date format.

I would not advise adding ValueTuple as a package reference to the .net Framework projects. As you know this assembly is available from 4.7 .NET Framework.

There can be certain situations when your project will try to include at all costs ValueTuple from .NET Framework folder instead of package folder and it can cause some assembly not found errors.

We had this problem today in company. We had solution with 2 projects (I oversimplify that) :

• Lib
• Web

Lib was including ValueTuple and Web was using Lib. It turned out that by some unknown reason Web when trying to resolve path to ValueTuple was having HintPath into .NET Framework directory and was taking incorrect version. Our application was crashing because of that. ValueTuple was not defined in .csproj of Web nor HintPath for that assembly. The problem was very weird. Normally it would copy the assembly from package folder. This time was not normal.

For me it is always risk to add System.* package references. They are often like time-bomb. They are fine at start and they can explode in your face in the worst moment. My rule of thumb: Do not use System.* Nuget package for .NET Framework if there is no real need for them.

We resolved our problem by adding manually ValueTuple into .csproj file inside Web project.

Use the following extensions and just pass the action like:

_frmx.PerformSafely(() => _frmx.Show());
_frmx.PerformSafely(() => _frmx.Location = new Point(x,y));

Extension class:

public static class CrossThreadExtensions
{
    public static void PerformSafely(this Control target, Action action)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action);
        }
        else
        {
            action();
        }
    }

    public static void PerformSafely<T1>(this Control target, Action<T1> action,T1 parameter)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action, parameter);
        }
        else
        {
            action(parameter);
        }
    }

    public static void PerformSafely<T1,T2>(this Control target, Action<T1,T2> action, T1 p1,T2 p2)
    {
        if (target.InvokeRequired)
        {
            target.Invoke(action, p1,p2);
        }
        else
        {
            action(p1,p2);
        }
    }
}

If I got you correctly, it is as easy as

cartDiv.id = "someID";

No need for jQuery.

Have a look at the properties of a DOM Element.

For classes it is the same:

cartDiv.className = "classes here";

But note that this will overwrite already existing class names. If you want to add and remove classes dynamically, you either have to use jQuery or write your own function that does some string replacement.

When you want to destroy a session completely, you need to do more then just

session_destroy();

First, you should unset any session variables. Then you should destroy the session followed by closing the write of the session. This can be done by the following:

<?php
session_start();
unset($_SESSION);
session_destroy();
session_write_close();
header('Location: /');
die;
?>

The reason you want have a separate script for a logout is so that you do not accidently execute it on the page. So make a link to your logout script, then the header will redirect to the root of your site.

Edit:

You need to remove the () from your exit code near the top of your script. it should just be

exit;

variable=" Hello..."  
print (variable)  
print("This is the Test File "+variable)  

for integer type ...

variable="  10"  
print (variable)  
print("This is the Test File "+str(variable))  

You're missing *s in the last two terms of your expression, so R is interpreting (e.g.) 0.207 (log(DIAM93))^2 as an attempt to call a function named 0.207 ...

For example:

> 1 + 2*(3)
[1] 7
> 1 + 2 (3)

Error: attempt to apply non-function

Your (unreproducible) expression should read:

censusdata_20$AGB93 = WD * exp(-1.239 + 1.980 * log (DIAM93) + 
                              0.207* (log(DIAM93))^2  -
                              0.0281*(log(DIAM93))^3)

Mathematica is the only computer system I know of that allows juxtaposition to be used for multiplication ...

import yaml

data = dict(
    A = 'a',
    B = dict(
        C = 'c',
        D = 'd',
        E = 'e',
    )
)

with open('data.yml', 'w') as outfile:
    yaml.dump(data, outfile, default_flow_style=False)

The default_flow_style=False parameter is necessary to produce the format you want (flow style), otherwise for nested collections it produces block style:

A: a
B: {C: c, D: d, E: e}

Windows has two different settings in which priority is established. There is the metric value which you have already set in the adapter settings, and then there is the connection priority in the network connections settings.

To change the priority of the connections:

• Open your Adapter Settings (Control Panel\Network and Internet\Network Connections)
• Click Alt to pull up the menu bar
• Select Advanced -> Advanced Settings
• Change the order of the connections so that the connection you want to have priority is top on the list

Here's a script I used to batch import a bunch of crt files in the current directory into the java keystore. Just save this to the same folder as your certificate, and run it like so:

./import_all_certs.sh

import_all_certs.sh

KEYSTORE="$(/usr/libexec/java_home)/jre/lib/security/cacerts";

function running_as_root()
{
  if [ "$EUID" -ne 0 ]
    then echo "NO"
    exit
  fi

  echo "YES"
}

function import_certs_to_java_keystore
{
  for crt in *.crt; do 
    echo prepping $crt 
    keytool -import -file $crt -storepass changeit -noprompt --alias alias__${crt} -keystore $KEYSTORE
    echo 
  done
}

if [ "$(running_as_root)" == "YES" ]
then
  import_certs_to_java_keystore
else
  echo "This script needs to be run as root!"
fi

An explanation of the following error:

org.postgresql.util.PSQLException: FATAL: sorry, too many clients already.

Summary:

You opened up more than the allowed limit of connections to the database. You ran something like this: Connection conn = myconn.Open(); inside of a loop, and forgot to run conn.close();. Just because your class is destroyed and garbage collected does not release the connection to the database. The quickest fix to this is to make sure you have the following code with whatever class that creates a connection:

protected void finalize() throws Throwable  
{  
    try { your_connection.close(); } 
    catch (SQLException e) { 
        e.printStackTrace();
    }
    super.finalize();  
}  

Place that code in any class where you create a Connection. Then when your class is garbage collected, your connection will be released.

Run this SQL to see postgresql max connections allowed:

show max_connections;

The default is 100. PostgreSQL on good hardware can support a few hundred connections at a time. If you want to have thousands, you should consider using connection pooling software to reduce the connection overhead.

Take a look at exactly who/what/when/where is holding open your connections:

SELECT * FROM pg_stat_activity;

The number of connections currently used is:

SELECT COUNT(*) from pg_stat_activity;

Debugging strategy

1. You could give different usernames/passwords to the programs that might not be releasing the connections to find out which one it is, and then look in pg_stat_activity to find out which one is not cleaning up after itself.

2. Do a full exception stack trace when the connections could not be created and follow the code back up to where you create a new Connection, make sure every code line where you create a connection ends with a connection.close();

How to set the max_connections higher:

max_connections in the postgresql.conf sets the maximum number of concurrent connections to the database server.

1. First find your postgresql.conf file
2. If you don't know where it is, query the database with the sql: SHOW config_file;
3. Mine is in: /var/lib/pgsql/data/postgresql.conf
4. Login as root and edit that file.
5. Search for the string: "max_connections".
6. You'll see a line that says max_connections=100.
7. Set that number bigger, check the limit for your postgresql version.
8. Restart the postgresql database for the changes to take effect.

What's the maximum max_connections?

Use this query:

select min_val, max_val from pg_settings where name='max_connections';

I get the value 8388607, in theory that's the most you are allowed to have, but then a runaway process can eat up thousands of connections, and surprise, your database is unresponsive until reboot. If you had a sensible max_connections like 100. The offending program would be denied a new connection.

PyPI packages not in the standard library:

• virtualenv is a very popular tool that creates isolated Python environments for Python libraries. If you're not familiar with this tool, I highly recommend learning it, as it is a very useful tool, and I'll be making comparisons to it for the rest of this answer.

  It works by installing a bunch of files in a directory (eg: env/), and then modifying the PATH environment variable to prefix it with a custom bin directory (eg: env/bin/). An exact copy of the python or python3 binary is placed in this directory, but Python is programmed to look for libraries relative to its path first, in the environment directory. It's not part of Python's standard library, but is officially blessed by the PyPA (Python Packaging Authority). Once activated, you can install packages in the virtual environment using pip.

• pyenv is used to isolate Python versions. For example, you may want to test your code against Python 2.7, 3.6, 3.7 and 3.8, so you'll need a way to switch between them. Once activated, it prefixes the PATH environment variable with ~/.pyenv/shims, where there are special files matching the Python commands (python, pip). These are not copies of the Python-shipped commands; they are special scripts that decide on the fly which version of Python to run based on the PYENV_VERSION environment variable, or the .python-version file, or the ~/.pyenv/version file. pyenv also makes the process of downloading and installing multiple Python versions easier, using the command pyenv install.

• pyenv-virtualenv is a plugin for pyenv by the same author as pyenv, to allow you to use pyenv and virtualenv at the same time conveniently. However, if you're using Python 3.3 or later, pyenv-virtualenv will try to run python -m venv if it is available, instead of virtualenv. You can use virtualenv and pyenv together without pyenv-virtualenv, if you don't want the convenience features.

• virtualenvwrapper is a set of extensions to virtualenv (see docs). It gives you commands like mkvirtualenv, lssitepackages, and especially workon for switching between different virtualenv directories. This tool is especially useful if you want multiple virtualenv directories.

• pyenv-virtualenvwrapper is a plugin for pyenv by the same author as pyenv, to conveniently integrate virtualenvwrapper into pyenv.

• pipenv aims to combine Pipfile, pip and virtualenv into one command on the command-line. The virtualenv directory typically gets placed in ~/.local/share/virtualenvs/XXX, with XXX being a hash of the path of the project directory. This is different from virtualenv, where the directory is typically in the current working directory. pipenv is meant to be used when developing Python applications (as opposed to libraries). There are alternatives to pipenv, such as poetry, which I won't list here since this question is only about the packages that are similarly named.

Standard library:

• pyvenv is a script shipped with Python 3 but deprecated in Python 3.6 as it had problems (not to mention the confusing name). In Python 3.6+, the exact equivalent is python3 -m venv.

• venv is a package shipped with Python 3, which you can run using python3 -m venv (although for some reason some distros separate it out into a separate distro package, such as python3-venv on Ubuntu/Debian). It serves the same purpose as virtualenv, but only has a subset of its features (see a comparison here). virtualenv continues to be more popular than venv, especially since the former supports both Python 2 and 3.

Recommendation for beginners:

This is my personal recommendation for beginners: start by learning virtualenv and pip, tools which work with both Python 2 and 3 and in a variety of situations, and pick up other tools once you start needing them.

I had a case where I was entering text into a field after which the text would be removed automatically. Turned out it was due to some site functionality where you had to press the enter key after entering the text into the field. So, after sending your barcode text with sendKeys method, send 'enter' directly after it. Note that you will have to import the selenium Keys class. See my code below.

import org.openqa.selenium.Keys;

String barcode="0000000047166";
WebElement element_enter = driver.findElement(By.xpath("//*[@id='div-barcode']"));
element_enter.findElement(By.xpath("your xpath")).sendKeys(barcode);

element_enter.sendKeys(Keys.RETURN); // this will result in the return key being pressed upon the text field

I hope it helps..

You are calling getWidth() too early. The UI has not been sized and laid out on the screen yet.

I doubt you want to be doing what you are doing, anyway -- widgets being animated do not change their clickable areas, and so the button will still respond to clicks in the original orientation regardless of how it has rotated.

That being said, you can use a dimension resource to define the button size, then reference that dimension resource from your layout file and your source code, to avoid this problem.

Running nginx -t through your commandline will issue out a test and append the output with the filepath to the configuration file (with either an error or success message).

Do a cross-domain AJAX call

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

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

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

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

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

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

I think Apple are covering their backs a little here for a potentially kludgy piece of API.

  [self dismissViewControllerAnimated:NO completion:nil]

Is actually a bit of a fiddle. Although you can - legitimately - call this on the presented view controller, all it does is forward the message on to the presenting view controller. If you want to do anything over and above just dismissing the VC, you will need to know this, and you need to treat it much the same way as a delegate method - as that's pretty much what it is, a baked-in somewhat inflexible delegate method.

Perhaps they've come across loads of bad code by people not really understanding how this is put together, hence their caution.

But of course, if all you need to do is dismiss the thing, go ahead.

My own approach is a compromise, at least it reminds me what is going on:

  [[self presentingViewController] dismissViewControllerAnimated:NO completion:nil]

[Swift]

  self.presentingViewController?.dismiss(animated: false, completion:nil)

If you use the CMake GUI then swap to the advanced view and then the option is called CMAKE_VERBOSE_MAKEFILE.

Set the name in the form to check_list[] and you will be able to access all the checkboxes as an array($_POST['check_list'][]).

Here's a little sample as requested:

<form action="test.php" method="post">
    <input type="checkbox" name="check_list[]" value="value 1">
    <input type="checkbox" name="check_list[]" value="value 2">
    <input type="checkbox" name="check_list[]" value="value 3">
    <input type="checkbox" name="check_list[]" value="value 4">
    <input type="checkbox" name="check_list[]" value="value 5">
    <input type="submit" />
</form>
<?php
if(!empty($_POST['check_list'])) {
    foreach($_POST['check_list'] as $check) {
            echo $check; //echoes the value set in the HTML form for each checked checkbox.
                         //so, if I were to check 1, 3, and 5 it would echo value 1, value 3, value 5.
                         //in your case, it would echo whatever $row['Report ID'] is equivalent to.
    }
}
?>

Try this

COALESCE(NULLIF(Address.COUNTRY,''), 'United States')

The printf command will print the complete strings:

(gdb) printf "%s\n", string

You can change the value of a bool all you want. As for an if:

if randombool == True:

works, but you can also use:

if randombool:

If you want to test whether something is false you can use:

if randombool == False

but you can also use:

if not randombool:

I was having the same problem and even though I was styling my button in CSS it would never pick up the border:none but what worked was adding a style directly on the input button like so:

<div style="text-align:center;">
    <input type="submit" class="SubmitButtonClass" style="border:none;" value="" />
</div>

Please try this (if the browser does not support "onbeforeunload"):

jQuery(document).ready(function($) {

  if (window.history && window.history.pushState) {

    $(window).on('popstate', function() {
      var hashLocation = location.hash;
      var hashSplit = hashLocation.split("#!/");
      var hashName = hashSplit[1];

      if (hashName !== '') {
        var hash = window.location.hash;
        if (hash === '') {
          alert('Back button was pressed.');
        }
      }
    });

    window.history.pushState('forward', null, './#forward');
  }

});

Here's an approach I'm using for ember 1.10 and ember-cli 2.0.

// app/helpers/js-x.js
export default Ember.HTMLBars.makeBoundHelper(function (params) {
  var paramNames = params.slice(1).map(function(val, idx) { return "p" + idx; });
  var func = Function.apply(this, paramNames.concat("return " + params[0] + ";"))
  return func.apply(params[1] === undefined ? this : params[1], params.slice(1));
});

Then you can use it in your templates like this:

// used as sub-expression
{{#each item in model}}
  {{#if (js-x "this.section1 || this.section2" item)}}
  {{/if}}
{{/each}}

// used normally
{{js-x "p0 || p1" model.name model.offer.name}}

Where the arguments to the expression are passed in as p0,p1,p2 etc and p0 can also be referenced as this.

I was having this issue and nothing worked. I ran xcode-select --install and also installed /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg.

BACKGROUND

Since I was having issues with App Store on a new laptop, I was forced to download the Xcode Beta installer from the Apple website to install Xcode outside App Store. So I only had Xcode Beta installed.

SOLUTION

This, (I think), was making clang to not find the SDKROOT directory /Applications/Xcode.app/...., because there is no Beta in the path, or maybe Xcode Beta simply doesn't install it (I don't know). To fix the issue, I had to remove Xcode Beta and resolve the App Store issue to install the release version.

tldr;

If you have Xcode Beta, try cleaning up everything and installing the release version before trying out the solutions that are working for other people.

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

With CSS positioning, you can place an element exactly where you want it on your page.

When you are going to use CSS positioning, the first thing you need to do is use the CSS property position to tell the browser if you're going to use absolute or relative positioning.

Both Positions are having different features. In CSS Once you set Position then you can able to use top, right, bottom, left attributes.

Absolute Position

An absolute position element is positioned relative to the first parent element that has a position other than static.

Relative Position

A relative positioned element is positioned relative to its normal position.

To position an element relatively, the property position is set as relative. The difference between absolute and relative positioning is how the position is being calculated.
