@RequestBody MultipartFile[] submissions

should be

@RequestParam("file") MultipartFile[] submissions

The files are not the request body, they are part of it and there is no built-in HttpMessageConverter that can convert the request to an array of MultiPartFile.

You can also replace HttpServletRequest with MultipartHttpServletRequest, which gives you access to the headers of the individual parts.

Please see below for a modest improvement on @Sled's code shown above, that turn-back-on method was missing one line, now it passes my tests. This disables HTTPS certificate and hostname spoofing when using RestTemplate in a Spring-Boot version 2 application that uses the default HTTP configuration, NOT configured to use Apache HTTP Client.

package org.my.little.spring-boot-v2.app;

import java.security.KeyManagementException;
import java.security.NoSuchAlgorithmException;
import java.security.cert.X509Certificate;

import javax.net.ssl.HostnameVerifier;

import javax.net.ssl.X509TrustManager;

/**

 * HttpsURLConnection, the default JVM implementation of the HTTPS/TLS protocol.
 * Has no effect on implementations such as Apache Http Client, Ok Http.
*/
public final class SSLUtils {

    private static final HostnameVerifier jvmHostnameVerifier = HttpsURLConnection.getDefaultHostnameVerifier();

    private static final HostnameVerifier trivialHostnameVerifier = new HostnameVerifier() {
        public boolean verify(String hostname, SSLSession sslSession) {
            return true;
        }
    };

    private static final TrustManager[] UNQUESTIONING_TRUST_MANAGER = new TrustManager[] { new X509TrustManager() {
        public java.security.cert.X509Certificate[] getAcceptedIssuers() {
            return null;
        }

        public void checkClientTrusted(X509Certificate[] certs, String authType) {
        }

        public void checkServerTrusted(X509Certificate[] certs, String authType) {
        }
    } };

    public static void turnOffSslChecking() throws NoSuchAlgorithmException, KeyManagementException {
        HttpsURLConnection.setDefaultHostnameVerifier(trivialHostnameVerifier);
        // Install the all-trusting trust manager
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, UNQUESTIONING_TRUST_MANAGER, null);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    }

    public static void turnOnSslChecking() throws KeyManagementException, NoSuchAlgorithmException {
        HttpsURLConnection.setDefaultHostnameVerifier(jvmHostnameVerifier);
        // Return it to the initial state (discovered by reflection, now hardcoded)
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, null, null);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

Stan0 intial idea is not a good idea. There can be multiple files with the same name. Very error prone implementation. Stan0's second idea is the correct way.

When you first upload the file to google drive store its id (in SharedPreferences is probably easiest) for later use

ie.

file= mDrive.files().insert(body).execute();      //initial insert of file to google drive

whereverYouWantToStoreIt= file.getId(); //now you have the guaranteed unique id 
                                        //of the file just inserted. Store it and use it 
                                        //whenever you need to fetch this file

For Spring Boot >= 1.4

@Configuration
public class AppConfig
{
    @Bean
    public RestTemplate restTemplate(RestTemplateBuilder restTemplateBuilder) 
    {
        return restTemplateBuilder
           .setConnectTimeout(...)
           .setReadTimeout(...)
           .build();
    }
}

For Spring Boot <= 1.3

@Configuration
public class AppConfig
{
    @Bean
    @ConfigurationProperties(prefix = "custom.rest.connection")
    public HttpComponentsClientHttpRequestFactory customHttpRequestFactory() 
    {
        return new HttpComponentsClientHttpRequestFactory();
    }

    @Bean
    public RestTemplate customRestTemplate()
    {
        return new RestTemplate(customHttpRequestFactory());
    }
}

then in your application.properties

custom.rest.connection.connection-request-timeout=...
custom.rest.connection.connect-timeout=...
custom.rest.connection.read-timeout=...

This works because HttpComponentsClientHttpRequestFactory has public setters connectionRequestTimeout, connectTimeout, and readTimeout and @ConfigurationProperties sets them for you.

For Spring 4.1 or Spring 5 without Spring Boot using @Configuration instead of XML

@Configuration
public class AppConfig
{
    @Bean
    public RestTemplate customRestTemplate()
    {
        HttpComponentsClientHttpRequestFactory httpRequestFactory = new HttpComponentsClientHttpRequestFactory();
        httpRequestFactory.setConnectionRequestTimeout(...);
        httpRequestFactory.setConnectTimeout(...);
        httpRequestFactory.setReadTimeout(...);

        return new RestTemplate(httpRequestFactory);
    }
}

It needs "slf4j-simple-1.7.2.jar" to resolve the problem.

I downloaded a zip file "slf4j-1.7.2.zip" from http://slf4j.org/download.html. I extracted the zip file and i got slf4j-simple-1.7.2.jar

If you don't want to convert the entire Map into an array beforehand, and/or destructure key-value arrays, you can use this silly function:

/**_x000D_
 * Map over an ES6 Map._x000D_
 *_x000D_
 * @param {Map} map_x000D_
 * @param {Function} cb Callback. Receives two arguments: key, value._x000D_
 * @returns {Array}_x000D_
 */_x000D_
function mapMap(map, cb) {_x000D_
  let out = new Array(map.size);_x000D_
  let i = 0;_x000D_
  map.forEach((val, key) => {_x000D_
    out[i++] = cb(key, val);_x000D_
  });_x000D_
  return out;_x000D_
}_x000D_
_x000D_
let map = new Map([_x000D_
  ["a", 1],_x000D_
  ["b", 2],_x000D_
  ["c", 3]_x000D_
]);_x000D_
_x000D_
console.log(_x000D_
  mapMap(map, (k, v) => `${k}-${v}`).join(', ')_x000D_
); // a-1, b-2, c-3

Use @Column annotation and define its length attribute. Check Hibernate's documentation for references (section 2.2.2.3).

Handlebars supports {{else if}} blocks as of 3.0.0.

Handlebars v3.0.0 or greater:

{{#if FriendStatus.IsFriend}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{else if FriendStatus.FriendRequested}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-check"><span class="ui-icon ui-icon-check"></span></div>
{{else}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
{{/if}}

Prior to Handlebars v3.0.0, however, you will have to either define a helper that handles the branching logic or nest if statements manually:

{{#if FriendStatus.IsFriend}}
  <div class="ui-state-default ui-corner-all" title=".ui-icon-mail-closed"><span class="ui-icon ui-icon-mail-closed"></span></div>
{{else}}
  {{#if FriendStatus.FriendRequested}}

  {{else}}
    <div class="ui-state-default ui-corner-all" title=".ui-icon-plusthick"><span class="ui-icon ui-icon-plusthick"></span></div>
  {{/if}}

You can call setScale(newScale, roundingMode) method three times with changing the newScale value from 4 to 3 to 2 like

First case

    BigDecimal a = new BigDecimal("10.12345");

    a = a.setScale(4, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.1235
    a = a.setScale(3, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.124
    a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println("" + a); //10.12

Second case

    BigDecimal a = new BigDecimal("10.12556");

    a = a.setScale(4, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.1256
    a = a.setScale(3, BigDecimal.ROUND_HALF_UP); 
    System.out.println("" + a); //10.126
    a = a.setScale(2, BigDecimal.ROUND_HALF_UP);
    System.out.println("" + a); //10.13

Sorry for the necropost but this is what I turned up with google and since I found this helpful but problematic I wanted to contribute an important modification for anyone else who digs this up.

First off, I'm using SQL Server, not MySQL, but I think it should work similarly. I used Leonard Challis' solution because it was simplest and met the need, however there's a problem with this - if you simply take the PK and increment it by 1 then what happens if you've added other records since the row in question was added. I decided it was best to just let the system handle the autoincrementing of the PK, so I did the following:

SELECT * INTO #tmpTable FROM Table WHERE primarykey = 1
--Optionally you can modify one or more fields here like this: 
--UPDATE #tmpTable SET somefield = newData
ALTER TABLE #tmpTable DROP COLUMN TicketUpdateID
INSERT INTO Tickets SELECT * FROM #tmpTable
DROP TABLE #tmpTable

I believe this would work similarly in MySQL, but I can't test this, sorry

<Files ".ht*">
 Require all denied
</Files>

 replace to

<Files ".ht*">
 Require local
</Files>

"aoColumnDefs" : [   
{
  'bSortable' : false,  
  'aTargets' : [ 0 ]
}]

Here 0 is the index of the column, if you want multiple columns to be not sorted, mention column index values seperated by comma(,)

A WAR (Web Archive) is a module that gets loaded into a Web container of a Java Application Server. A Java Application Server has two containers (runtime environments) - one is a Web container and the other is a EJB container.

The Web container hosts Web applications based on JSP or the Servlets API - designed specifically for web request handling - so more of a request/response style of distributed computing. A Web container requires the Web module to be packaged as a WAR file - that is a special JAR file with a web.xml file in the WEB-INF folder.

An EJB container hosts Enterprise java beans based on the EJB API designed to provide extended business functionality such as declarative transactions, declarative method level security and multiprotocol support - so more of an RPC style of distributed computing. EJB containers require EJB modules to be packaged as JAR files - these have an ejb-jar.xml file in the META-INF folder.

Enterprise applications may consist of one or more modules that can either be Web modules (packaged as a WAR file), EJB modules (packaged as a JAR file), or both of them. Enterprise applications are packaged as EAR files - these are special JAR files containing an application.xml file in the META-INF folder.

Basically, EAR files are a superset containing WAR files and JAR files. Java Application Servers allow deployment of standalone web modules in a WAR file, though internally, they create EAR files as a wrapper around WAR files. Standalone web containers such as Tomcat and Jetty do not support EAR files - these are not full-fledged Application servers. Web applications in these containers are to be deployed as WAR files only.

In application servers, EAR files contain configurations such as application security role mapping, EJB reference mapping and context root URL mapping of web modules.

Apart from Web modules and EJB modules, EAR files can also contain connector modules packaged as RAR files and Client modules packaged as JAR files.

One possible option to implement such behavior is

PUT /groups/api/v1/groups/{group id}/status
{
    "Status":"Activated"
}

And obviously, if someone need to deactivate it, PUT will have Deactivated status in JSON.

In case of necessity of mass activation/deactivation, PATCH can step into the game (not for exact group, but for groups resource:

PATCH /groups/api/v1/groups
{
    { “op”: “replace”, “path”: “/group1/status”, “value”: “Activated” },
    { “op”: “replace”, “path”: “/group7/status”, “value”: “Activated” },
    { “op”: “replace”, “path”: “/group9/status”, “value”: “Deactivated” }
}

In general this is idea as @Andrew Dobrowolski suggesting, but with slight changes in exact realization.

You can style it using javascript and css. Add the style to css and using javascript add/remove style using classlist property. Here is a JSFiddle for it.

  <div class="div-image-text">
    <input class="input-image-url" type="text" placeholder="Add text" name="input-image">
    <input type="button" onclick="addRemoteImage(event);" value="Submit">
  </div>
  <div class="no-image-url-error" name="input-image-error">Textbox empty</div>

addRemoteImage = function(event) {
  var textbox = document.querySelector("input[name='input-image']"),
    imageUrl = textbox.value,
    errorDiv = document.querySelector("div[name='input-image-error']");
  if (imageUrl == "") {
    errorDiv.style.display = "block";
    textbox.classList.add('text-error');
    setTimeout(function() {
      errorDiv.style.removeProperty('display');
      textbox.classList.remove('text-error');
    }, 3000);
  } else {
    textbox.classList.remove('text-error');
  }
}

Implement onClick() method in your Activity/Fragment public class MainActivity extends Activity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public void onClick(View v) {
 switch (itemId) {

// if you call the fragment with nevigation bar then used.

           case R.id.nav_menu1:
                fragment = new IntroductionFragment();
                break;

// if call activity with nevigation bar then used.

            case R.id.nav_menu6:
                Intent i = new Intent(MainActivity.this, YoutubeActivity.class);
                startActivity(i);
      // default method for handling onClick Events..
    }
}

I take a totally different approach to everyone else's answers here altogether. Let me prefix my solution and argue by stating that sometimes standards and conventions are meant to be broken, especially in the context of the standard HTML lexical tag definitions.

There's nothing to stop you from creating custom elements that are self-descriptive to it's very purpose.

Both modern browsers and even IE 6+ (w/ shim) can support things like:

<icon class="plus">

or

<icon-add>

Just make sure to normalize the tag:

 icon { display:block; margin:0; padding:0; border:0; ... }

and use a shim if you need to support IE9 or earlier (see post below).

Check out this StackOverflow Post:

Is there a way to create your own html tag in HTML5

To further my argument, both Google's Angular Directives and the new Polymer projects utilize the concept of custom HTML tags.

You need to tell the run to wait until the process is finished. Something like:

const DontWaitUntilFinished = false, ShowWindow = 1, DontShowWindow = 0, WaitUntilFinished = true
set oShell = WScript.CreateObject("WScript.Shell")
command = "cmd /c C:\windows\system32\wscript.exe <path>\myScript.vbs " & args
oShell.Run command, DontShowWindow, WaitUntilFinished

In the script itself, start Excel like so. While debugging start visible:

File = "c:\test\myfile.xls"
oShell.run """C:\Program Files\Microsoft Office\Office14\EXCEL.EXE"" " & File, 1, true

if the database is InnoDB you dont need to do joins in deletion. only

DELETE FROM spawnlist WHERE spawnlist.type = "monster";

can be used to delete the all the records that linked with foreign keys in other tables, to do that you have to first linked your tables in design time.

CREATE TABLE IF NOT EXIST spawnlist (
  npc_templateid VARCHAR(20) NOT NULL PRIMARY KEY

)ENGINE=InnoDB;

CREATE TABLE IF NOT EXIST npc (
  idTemplate VARCHAR(20) NOT NULL,

  FOREIGN KEY (idTemplate) REFERENCES spawnlist(npc_templateid) ON DELETE CASCADE

)ENGINE=InnoDB;

if you uses MyISAM you can delete records joining like this

DELETE a,b
FROM `spawnlist` a
JOIN `npc` b
ON a.`npc_templateid` = b.`idTemplate`
WHERE a.`type` = 'monster';

in first line i have initialized the two temp tables for delet the record, in second line i have assigned the existance table to both a and b but here i have linked both tables together with join keyword, and i have matched the primary and foreign key for both tables that make link, in last line i have filtered the record by field to delete.

Just a slight solution change for checking the version of numpy with Python,

import numpy as np 
print("Numpy Version:",np.__version__)

Or,

import numpy as np
print("Numpy Version:",np.version.version)

My projects in PyCharm are currently running version

1.17.4

In the context of application development, "bootstrapping" usually comes up when talking about modular and/or auto-updatable software.

Rather than the user downloading the entire app, including features he does not need, and re-downloading and manually updating it whenever there is an update, the user only downloads and starts a small "bootstrap" executable, which in turn downloads and installs those parts of the application that the user needs. Additionally, the bootstrap component is able to look for updates and install them each time it is started.

Yes, you can concatenate using a + sign. Kotlin has string templates, so it's better to use them like:

var fn = "Hello"
var ln = "World"

"$fn $ln" for concatenation.

You can even use String.plus() method.

If you're using C# 3.0 you can use linq, way better and way more elegant:

List<int> myList = GetListOfIntsFromSomewhere();

// This will filter out the list of ints that are > than 7, Where returns an
// IEnumerable<T> so a call to ToList is required to convert back to a List<T>.
List<int> filteredList = myList.Where( x => x > 7).ToList();

If you can't find the .Where, that means you need to import using System.Linq; at the top of your file.

My solution is almost the same as the original answer but it doesn't worked for me.

So, I gave names for the columns and it works:

painel <- rbind(painel, data.frame("col1" = xtweets$created_at,
                                   "col2" = xtweets$text))

You'd use the corresponding method getVisibility(). Method names prefixed with 'get' and 'set' are Java's convention for representing properties. Some language have actual language constructs for properties but Java isn't one of them. So when you see something labeled 'setX', you can be 99% certain there's a corresponding 'getX' that will tell you the value.

Easy! Just use jQuery's click function:

$("#theElement").click();

In my case I resolved that problem using such approach:

1. Set new environment variable: JAVA_TOOL_OPTIONS = -Dfile.encoding=UTF8
2. Or set MAVEN_OPTS= -Dfile.encoding=UTF-8

str.join() works fine in Python 3, you just need to get the order of the arguments correct

>>> str.join('.', ('a', 'b', 'c'))
'a.b.c'

There are two differences:

1. We can use Iterator to traverse Set and List and also Map type of Objects. While a ListIterator can be used to traverse for List-type Objects, but not for Set-type of Objects.

   That is, we can get a Iterator object by using Set and List, see here:

   By using Iterator we can retrieve the elements from Collection Object in forward direction only.

   Methods in Iterator:

   1. hasNext()
   2. next()
   3. remove()

   Iterator iterator = Set.iterator();
   Iterator iterator = List.iterator();

2. But we get ListIterator object only from the List interface, see here:

   where as a ListIterator allows you to traverse in either directions (Both forward and backward). So it has two more methods like hasPrevious() and previous() other than those of Iterator. Also, we can get indexes of the next or previous elements (using nextIndex() and previousIndex() respectively )

   Methods in ListIterator:

   1. hasNext()
   2. next()
   3. previous()
   4. hasPrevious()
   5. remove()
   6. nextIndex()
   7. previousIndex()

   ListIterator listiterator = List.listIterator();

   i.e., we can't get ListIterator object from Set interface.

Reference : - What is the difference between Iterator and ListIterator ?

Just 2 things I think make it ALWAYS preferable to use a # Temp Table rather then a CTE are:

1. You can not put a primary key on a CTE so the data being accessed by the CTE will have to traverse each one of the indexes in the CTE's tables rather then just accessing the PK or Index on the temp table.

2. Because you can not add constraints, indexes and primary keys to a CTE they are more prone to bugs creeping in and bad data.

-onedaywhen yesterday

Here is an example where #table constraints can prevent bad data which is not the case in CTE's

DECLARE @BadData TABLE ( 
                       ThisID int
                     , ThatID int );
INSERT INTO @BadData
       ( ThisID
       , ThatID
       ) 
VALUES
       ( 1, 1 ),
       ( 1, 2 ),
       ( 2, 2 ),
       ( 1, 1 );

IF OBJECT_ID('tempdb..#This') IS NOT NULL
    DROP TABLE #This;
CREATE TABLE #This ( 
             ThisID int NOT NULL
           , ThatID int NOT NULL
                        UNIQUE(ThisID, ThatID) );
INSERT INTO #This
SELECT * FROM @BadData;
WITH This_CTE
     AS (SELECT *
           FROM @BadData)
     SELECT *
       FROM This_CTE;

Download your svg as text.

Modify your svg text using javascript to change the paint/stroke/fill color[s].

Then embed the modified svg string inline into your css as described here.

Depending on your platform you can use: sqlite3 file_name.db from the terminal. .tables will list the tables, .schema is full layout. SQLite commands like: select * from table_name; and such will print out the full contents. Type: ".exit" to exit. No need to download a GUI application.Use a semi-colon if you want it to execute a single command. Decent SQLite usage tutorial http://www.thegeekstuff.com/2012/09/sqlite-command-examples/

LocalDate maxDate = dates.stream()
                            .max( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();

LocalDate minDate = dates.stream()
                            .min( Comparator.comparing( LocalDate::toEpochDay ) )
                            .get();

echo "Please enter some input: "
read input_variable
echo "You entered: $input_variable"

struct emp {
    int id;
    char *name;
};

struct emp get() {
    char *name = "John";

    struct emp e1 = {100, name};

    return (e1);
}

int main() {

    struct emp e2 = get();

    printf("%s\n", e2.name);
}

works fine with newer versions of compilers. Just like id, content of the name gets copied to the assigned structure variable.

use simple code for remove default browser style for outline

input { outline: none; }

Remember load jquery before bootstrap js

First, of Start the Mongo DB - for that go to the path as ->

C:\Program Files\MongoDB\Server\3.2\bin and click on the mongod.exe file to start MongoDB server.

Command in Windows to Export

• Command to export MongoDB database in Windows from "remote-server" to the local machine in directory C:/Users/Desktop/temp-folder from the remote server with the internal IP address and port.

C:> mongodump --host remote_ip_address:27017 --db -o C:/Users/Desktop/temp-folder

Command in Windows to Import

• Command to import MongoDB database in Windows to "remote-server" from local machine directory C:/Users/Desktop/temp-folder/db-dir

C:> mongorestore --host=ip --port=27017 -d C:/Users/Desktop/temp-folder/db-dir

In compact edition will take size automatically for datetime data type i.e. (8) so no need to set size of field and generate error for this operation...

You are still in the context of your CategoryController even though you're loading a PartialView from your Views/News folder.

Remember that a single = is always an assignment in C or C++.

Your test should be if ( match == 0 && k == M )you made a typo on the k == M test.

If you really mean k=M (i.e. a side-effecting assignment inside a test) you should for readability reasons code if (match == 0 && (k=m) != 0) but most coding rules advise not writing that.

BTW, your mistake suggests to ask for all warnings (e.g. -Wall option to g++), and to upgrade to recent compilers. The next GCC 4.8 will give you:

 % g++-trunk -Wall -c ederman.cc
 ederman.cc: In function ‘void foo()’:
 ederman.cc:9:30: error: lvalue required as left operand of assignment
          if ( match == 0 && k = M )
                               ^

and Clang 3.1 also tells you ederman.cc:9:30: error: expression is not assignable

So use recent versions of free compilers and enable all the warnings when using them.

Step1. $ cd [your working path of code]

Step2. $ svn commit [your server path ] -m 'Add commit message'

For help use $ svn help commit

It is so easy for both scenarios (that is, synchronous/asynchronous) if you want to trigger a server-side event handler, for example, Button's click event.

For triggering an event handler of a control: If you added a ScriptManager on your page already then skip step 1.

1. Add the following in your page client script section

   //<![CDATA[
   var theForm = document.forms['form1'];
   if (!theForm) {
       theForm = document.form1;
   }
   function __doPostBack(eventTarget, eventArgument) {
       if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
           theForm.__EVENTTARGET.value = eventTarget;
           theForm.__EVENTARGUMENT.value = eventArgument;
           theForm.submit();
       }

   2. Write you server side event handler for your control

      protected void btnSayHello_Click(object sender, EventArgs e) { Label1.Text = "Hello World..."; }

   3. Add a client function to call the server side event handler

      function SayHello() { __doPostBack("btnSayHello", ""); }

Replace the "btnSayHello" in code above with your control's client id.

By doing so, if your control is inside an update panel, the page will not refresh. That is so easy.

One other thing to say is that: Be careful with client id, because it depends on you ID-generation policy defined with the ClientIDMode property.

When running this command:

ALTER TABLE MYTABLENAME MODIFY CONSTRAINT MYCONSTRAINTNAME_FK ENABLE;

I got this error:

ORA-02270: no matching unique or primary key for this column-list
02270. 00000 -  "no matching unique or primary key for this column-list"
*Cause:    A REFERENCES clause in a CREATE/ALTER TABLE statement
          gives a column-list for which there is no matching unique or primary
          key constraint in the referenced table.
*Action:   Find the correct column names using the ALL_CONS_COLUMNS

The referenced table has a primary key constraint with matching type. The root cause of this error, in my case, was that the primary key constraint was disabled.

I just came across this post and thought of posting my solution, just in case of anyone being in the same situation as me, where there are quite some files in the developed program, and you don't have the time to think through the whole import sequence of your modules (if you didn't think of that properly right from the start, such as I did).

In such cases, in the script where you initiate your global(s), simply code a class which says like:

class My_Globals:
  def __init__(self):
    self.global1 = "initial_value_1"
    self.global2 = "initial_value_2"
    ...

and then use, instead of the line in the script where you initiated your globals, instead of

global1 = "initial_value_1"

use

globals = My_Globals()

I was then able to retrieve / change the values of any of these globals via

globals.desired_global

in any script, and these changes were automatically also applied to all the other scripts using them. All worked now, by using the exact same import statements which previously failed, due to the problems mentioned in this post / discussion here. I simply thought of global object's properties being changing dynamically without the need of considering / changing any import logic, in comparison to simple importing of global variables, and that definitely was the quickest and easiest (for later access) approach to solve this kind of problem for me.

I would recommend using Git Graph extension.

Another option is to use \dfrac instead of \frac, which makes the whole fraction larger and hence more readable.

And no, I don't know if there is an option to get something in between \frac and \dfrac, sorry.

I know this MIGHT not be the cause of your issue, but I've spent a few hours hitting my head against the wall to solve this issue and this is my solution.

(running Windows 10 x32)

So I had installed XAMPP in a deeply nested directory and all the conf files make reference to root\xampp\apache, whereas my files were some_dir\another_dir\whatthehelliswrongwithme\finally\xampp\apache

so my options were to either go through and edit all \xampp\apache references and point them at the right place, OR, the much simpler option... reinstall XAMPP at the root, so the references all point to the right place.

A little annoying, but I guess that's what we get when Mac and Windows try to be friends..

Hope it helps a few of you.

Your code reads

$pdf->InsertText('Line one\n\nLine two');

I don't know about the PDF library you're using but normally if you want \n to be interpreted as a line break you must use double quotes in PHP, e.g.

$pdf->InsertText("Line one\n\nLine two");

In fact in the last answer String strAsciiTab = Character.toString((char) iAsciiValue); the essential part is (char)iAsciiValue which is doing the job (Character.toString useless)

Meaning the first answer was correct actually char ch = (char) yourInt;

if in yourint=49 (or 0x31), ch will be '1'

The data.table package has its IDate class and functionalities similar to lubridate or the zoo package. You could do:

dt = data.table(
  Name = c('Joe', 'Amy', 'John'),
  JoiningDate = c('12/31/09', '10/28/09', '05/06/10'),
  AmtPaid = c(1000, 100, 200)
)

require(data.table)
dt[ , JoiningDate := as.IDate(JoiningDate, '%m/%d/%y') ]

If you need something to be able to added dynamically, c# attributes aren't the way. Look into storing the data in xml. I recently did a project that i started w/ attributes, but eventually moved to serialization w/ xml.

Try this:

$str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
}, $str);

In case it's UTF-16 based C/C++/Java/Json-style:

$str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UTF-16BE');
}, $str);

You need an IP-address-based reverse geocoding API... like the one from ipdata.co. I'm sure there are plenty of options available.

You may want to allow the user to override this, however. For example, they could be on a corporate VPN which makes the IP address look like it's in a different country.

I actually found the right command to use.. its called timeout: http://www.ss64.com/nt/timeout.html

For Windows 7,

Control Panel --> Programs --> Uninstall

, then

choose the python package to remove.

You can like this:

#{requestScope["paramName"]} ,#{sessionScope["paramName"]}

Because requestScope or sessionScope is a Map object.

Create a "module" object and declare variables in there. Unlike class-objects that have to be instantiated each time, the module objects are always available. Therefore, a public variable, function, or property in a "module" will be available to all the other objects in the VBA project, macro, Excel formula, or even within a MS Access JET-SQL query def.

Like this.

SELECT DISTINCT COL_NAME FROM myTable WHERE COL_NAME iLIKE '%Priceorder%'

Try adding:

and:

angular.module('MyApp', ['ngRoute','ngResource']);
function TwitterCtrl($scope,$resource){
}

You should call angular.module only once with all dependencies because with your current code, you're creating a new MyApp module overwriting the previous one.

From angular documentation:

Beware that using angular.module('myModule', []) will create the module myModule and overwrite any existing module named myModule. Use angular.module('myModule') to retrieve an existing module.

From the ISO draft for C++ (ISO/IEC JTC 1/SC 22 N 4411)

So destructors should generally catch exceptions and not let them propagate out of the destructor.

3 The process of calling destructors for automatic objects constructed on the path from a try block to a throw- expression is called “stack unwinding.” [ Note: If a destructor called during stack unwinding exits with an exception, std::terminate is called (15.5.1). So destructors should generally catch exceptions and not let them propagate out of the destructor. — end note ]

The word complement derives from completeness. In the decimal world the numerals 0 through 9 provide a complement (complete set) of numerals or numeric symbols to express all decimal numbers. In the binary world the numerals 0 and 1 provide a complement of numerals to express all binary numbers. In fact The symbols 0 and 1 must be used to represent everything (text, images, etc) as well as positive (0) and negative (1). In our world the blank space to the left of number is considered as zero:

                  35=035=000000035.

In a computer storage location there is no blank space. All bits (binary digits) must be either 0 or 1. To efficiently use memory numbers may be stored as 8 bit, 16 bit, 32 bit, 64 bit, 128 bit representations. When a number that is stored as an 8 bit number is transferred to a 16 bit location the sign and magnitude (absolute value) must remain the same. Both 1's complement and 2's complement representations facilitate this. As a noun: Both 1's complement and 2's complement are binary representations of signed quantities where the most significant bit (the one on the left) is the sign bit. 0 is for positive and 1 is for negative. 2s complement does not mean negative. It means a signed quantity. As in decimal the magnitude is represented as the positive quantity. The structure uses sign extension to preserve the quantity when promoting to a register [] with more bits:

       [0101]=[00101]=[00000000000101]=5 (base 10)
       [1011]=[11011]=[11111111111011]=-5(base 10)

As a verb: 2's complement means to negate. It does not mean make negative. It means if negative make positive; if positive make negative. The magnitude is the absolute value:

        if a >= 0 then |a| = a
        if a < 0 then |a| = -a = 2scomplement of a

This ability allows efficient binary subtraction using negate then add. a - b = a + (-b)

The official way to take the 1's complement is for each digit subtract its value from 1.

        1'scomp(0101) = 1010.

This is the same as flipping or inverting each bit individually. This results in a negative zero which is not well loved so adding one to te 1's complement gets rid of the problem. To negate or take the 2s complement first take the 1s complement then add 1.

        Example 1                             Example 2
         0101  --original number              1101
         1's comp  1010                       0010
         add 1     0001                       0001
         2's comp  1011  --negated number     0011

In the examples the negation works as well with sign extended numbers.

Adding:
1110 Carry 111110 Carry 0110 is the same as 000110 1111 111111 sum 0101 sum 000101

SUbtracting:

    1110  Carry                      00000   Carry
     0110          is the same as     00110
    -0111                            +11001
  ----------                        ----------
sum  0101                       sum   11111

Notice that when working with 2's complement, blank space to the left of the number is filled with zeros for positive numbers butis filled with ones for negative numbers. The carry is always added and must be either a 1 or 0.

I see plots with the use of (.circle) but based on what you might want to do you can also try this out:

import matplotlib.pyplot as plt
import numpy as np

x = list(range(1,6))
y = list(range(10, 20, 2))

print(x, y)

for i, data in enumerate(zip(x,y)):
    j, k = data
    plt.scatter(j,k, marker = "o", s = ((i+1)**4)*50, alpha = 0.3)

centers = np.array([[5,18], [3,14], [7,6]])
m, n = make_blobs(n_samples=20, centers=[[5,18], [3,14], [7,6]], n_features=2, 
cluster_std = 0.4)
colors = ['g', 'b', 'r', 'm']

plt.figure(num=None, figsize=(7,6), facecolor='w', edgecolor='k')
plt.scatter(m[:,0], m[:,1])

for i in range(len(centers)):

    plt.scatter(centers[i,0], centers[i,1], color = colors[i], marker = 'o', s = 13000, alpha = 0.2)
    plt.scatter(centers[i,0], centers[i,1], color = 'k', marker = 'x', s = 50)

plt.savefig('plot.png')

A good seed generation for me is:

Random rand = new Random(Guid.NewGuid().GetHashCode());

It is very random. The seed is always different because the seed is also random generated.

If you are looking for a command-line based solution, you can ignore my answer. I am gonna suggest you to use GitKraken. It's an extraordinary git UI client. It shows the Git tree on the homepage. You can just look at them and know what is going on with the project. Just select a specific commit, right-click on it and select the option 'Create a branch here'. It will give you a text box to enter the branch name. Enter branch name, select 'OK' and you are set. It's really very easy to use.

Probably AES. Blowfish was the direct predecessor to Twofish. Twofish was Bruce Schneier's entry into the competition that produced AES. It was judged as inferior to an entry named Rijndael, which was what became AES.

Interesting aside: at one point in the competition, all the entrants were asked to give their opinion of how the ciphers ranked. It's probably no surprise that each team picked its own entry as the best -- but every other team picked Rijndael as the second best.

That said, there are some basic differences in the basic goals of Blowfish vs. AES that can (arguably) favor Blowfish in terms of absolute security. In particular, Blowfish attempts to make a brute-force (key-exhaustion) attack difficult by making the initial key setup a fairly slow operation. For a normal user, this is of little consequence (it's still less than a millisecond) but if you're trying out millions of keys per second to break it, the difference is quite substantial.

In the end, I don't see that as a major advantage, however. I'd generally recommend AES. My next choices would probably be Serpent, MARS and Twofish in that order. Blowfish would come somewhere after those (though there are a couple of others that I'd probably recommend ahead of Blowfish).

Guessing from the tag 'operand' you want to check a value?

$myValue = 5;
$minValue = 1;
$maxValue = 10;

if ($myValue >= $minValue && $myValue <= $maxValue) { 
  //do something
}

Not sure why the above explanations are so complicated when you have native methods available:

main_list = list(set(list_2)-set(list_1))

you can simply do this..

 <img src={"http://img.example.com/test/" + this.props.url +"/1.jpg"}/>

None of the existing answers quite offers a simple solution that returns "the number of rows that are just duplicates and should be cut out". This is a one-size-fits-all solution that does:

# generate a table of those culprit rows which are duplicated:
dups = df.groupby(df.columns.tolist()).size().reset_index().rename(columns={0:'count'})

# sum the final col of that table, and subtract the number of culprits:
dups['count'].sum() - dups.shape[0]

There are many variations possible for this problem. Here is a regular expression similar to an answer I previously placed on SO.

^\s*(?:\+?(\d{1,3}))?[-. (]*(\d{3})[-. )]*(\d{3})[-. ]*(\d{4})(?: *x(\d+))?\s*$

It would match the following examples and much more:

18005551234
1 800 555 1234
+1 800 555-1234
+86 800 555 1234
1-800-555-1234
1 (800) 555-1234
(800)555-1234
(800) 555-1234
(800)5551234
800-555-1234
800.555.1234
800 555 1234x5678
8005551234 x5678
1    800    555-1234
1----800----555-1234

Regardless of the way the phone number is entered, the capture groups can be used to breakdown the phone number so you can process it in your code.

• Group1: Country Code (ex: 1 or 86)
• Group2: Area Code (ex: 800)
• Group3: Exchange (ex: 555)
• Group4: Subscriber Number (ex: 1234)
• Group5: Extension (ex: 5678)

Here is a breakdown of the expression if you're interested:

^\s*                #Line start, match any whitespaces at the beginning if any.
(?:\+?(\d{1,3}))?   #GROUP 1: The country code. Optional.
[-. (]*             #Allow certain non numeric characters that may appear between the Country Code and the Area Code.
(\d{3})             #GROUP 2: The Area Code. Required.
[-. )]*             #Allow certain non numeric characters that may appear between the Area Code and the Exchange number.
(\d{3})             #GROUP 3: The Exchange number. Required.
[-. ]*              #Allow certain non numeric characters that may appear between the Exchange number and the Subscriber number.
(\d{4})             #Group 4: The Subscriber Number. Required.
(?: *x(\d+))?       #Group 5: The Extension number. Optional.
\s*$                #Match any ending whitespaces if any and the end of string.

To make the Area Code optional, just add a question mark after the (\d{3}) for the area code.

Building on mauretto's answer, this is a little easier to read and understand:

$('#mySelect').find('option').not(':first').remove();

To remove all the options except one with a specific value, you can use this:

$('#mySelect').find('option').not('[value=123]').remove();

This would be better if the option to be added was already there.

You are missing setter for salt property as indicated by the exception

Please add the setter as

 public void setSalt(long salt) {
      this.salt=salt;
 }

NOTE - it looks like the question has changed some. The answer to the question of how you call an instance method from a static method is that you can't without passing an instance in as an argument or instantiating that instance inside the static method.

What follows is mostly to answer "how do you call a static method from another static method":

Bear in mind that there is a difference between static methods and class methods in Python. A static method takes no implicit first argument, while a class method takes the class as the implicit first argument (usually cls by convention). With that in mind, here's how you would do that:

If it's a static method:

test.dosomethingelse()

If it's a class method:

cls.dosomethingelse()

Yes, you would use the header function.

/* Redirect browser */
header("Location: http://www.yourwebsite.com/user.php"); 
exit();

It is a good practice to call exit() right after it so that code below it does not get executed.

Also, from the documentation:

Remember that header() must be called before any actual output is sent, either by normal HTML tags, blank lines in a file, or from PHP. It is a very common error to read code with include(), or require(), functions, or another file access function, and have spaces or empty lines that are output before header() is called. The same problem exists when using a single PHP/HTML file.

This means you should not echo anything right before the header() function, as doing so will more than likely throw an error. Also, you will need to verify that this code gets run before any other output as well.

You might want to take a look at Standard Compression Scheme for Unicode.

SQL Server 2008 R2 use it internally and can achieve up to 50% compression.

Try this:

l1=[1,2,6,8]
l2=[2,3,5,8]
r=[]
for x in l1:
    if x in l2:
        continue
    r=r+[x]
print(r)

Spring uses dependency injection to populate the specific value when it finds the @Value annotation. However, instead of handing the value to the instance variable, it's handed to the implicit setter instead. This setter then handles the population of our NAME_STATIC value.

    @RestController 
//or if you want to declare some specific use of the properties file then use
//@Configuration
//@PropertySource({"classpath:application-${youeEnvironment}.properties"})
public class PropertyController {

    @Value("${name}")//not necessary
    private String name;//not necessary

    private static String NAME_STATIC;

    @Value("${name}")
    public void setNameStatic(String name){
        PropertyController.NAME_STATIC = name;
    }
}

here is an example, where the length of the array is changed during execution of the loop

import java.util.ArrayList;
public class VariableArrayLengthLoop {

public static void main(String[] args) {

    //create new ArrayList
    ArrayList<String> aListFruits = new ArrayList<String>();

    //add objects to ArrayList
    aListFruits.add("Apple");
    aListFruits.add("Banana");
    aListFruits.add("Orange");
    aListFruits.add("Strawberry");

    //iterate ArrayList using for loop
    for(int i = 0; i < aListFruits.size(); i++){

        System.out.println( aListFruits.get(i) + " i = "+i );
         if ( i == 2 ) {
                aListFruits.add("Pineapple");  
                System.out.println( "added now a Fruit to the List "); 
                }
        }
    }
}

From RFC2616 section 14.9.1

This is a good description of its uses and shortcomings. You essentially use it whenever you need to do fast low-level I/O. If you were going to implement a TCP/IP protocol or if you were writing a database (DBMS) this class would come in handy.

You just need to cast at least one of the operands to a float:

float z = (float) x / y;

or

float z = x / (float) y;

or (unnecessary)

float z = (float) x / (float) y;

To get your current location as start point you need to use this URL:

https://www.google.com/maps/dir/?api=1&origin=Current+Location&destination=<latitude>,<longitude>

You can fill up the destination parameter with the address, name or latitude and longitude values.

I wanted do download all the files from a webpage. I tried wget but it was failing so I decided for the Python route and I found this thread.

python3 soupget.py -p -e .xlsx .pdf .csv -u https://healthdata.gov/dataset/chemicals-cosmetics

I had this problem. As stated it is probably a static declaration issue. In my case it was because I had a static within a DEBUG clause. That is (in c#)

#if DEBUG
    public static bool DOTHISISINDEBUGONLY = false;
#endif

Everything worked fine until I complied a Release version of the code and after that I got this error - even on old release versions of the code. Once I took the variable out of the DEBUG clause everything returned to normal.

Another method is to create a superclass and then inherit it. This way you can use GCD more directly

class Lockable {
    let lockableQ:dispatch_queue_t

    init() {
        lockableQ = dispatch_queue_create("com.blah.blah.\(self.dynamicType)", DISPATCH_QUEUE_SERIAL)
    }

    func lock(closure: () -> ()) {
        dispatch_sync(lockableQ, closure)
    }
}


class Foo: Lockable {

    func boo() {
        lock {
            ....... do something
        }
    }

Try this SELECT DISTINCT 10 * ...

Model (App\Post.php):

/**
 * Get all comments for this post.
 */
public function comments($published = false)
{
    $comments = $this->hasMany('App\Comment');
    if($published) $comments->where('published', 1);

    return $comments;
}

Controller (App\Http\Controllers\PostController.php):

/**
 * Display the specified resource.
 *
 * @param int $id
 * @return \Illuminate\Http\Response
 */
public function post($id)
{
    $post = Post::with('comments')
        ->find($id);

    return view('posts')->with('post', $post);
}

Blade template (posts.blade.php):

{{-- Get all comments--}}
@foreach ($post->comments as $comment)
    code...
@endforeach

{{-- Get only published comments--}}
@foreach ($post->comments(true)->get() as $comment)
    code...
@endforeach

the above CSS can be written in SASS as follows (and it actually includes all button types, instead of just button.mat-button)

button,
a {
    &.mat-button,
    &.mat-raised-button,
    &.mat-flat-button,
    &.mat-stroked-button {
        .mat-icon {
            vertical-align: top;
            font-size: 1.25em;
        }
    }
}

simplest way in Python to get the mode of an list or array a

   import statistics
   print("mode = "+str(statistics.(mode(a)))

That's it

You need not specify the classes folder. Intellij should be able to load it. You will get this error if "Project Compiler output" is blank.

Just make sure that below value is set: Project Settings -> Project -> Project Compiler output to your projectDir/out folder

You can't do it easily. In C and Objective-C, enums are really just glorified integer constants. You'll have to generate a table of names yourself (or with some preprocessor abuse). For example:

// In a header file
typedef enum FormatType {
    JSON,
    XML,
    Atom,
    RSS
} FormatType;

extern NSString * const FormatType_toString[];

// In a source file
// initialize arrays with explicit indices to make sure 
// the string match the enums properly
NSString * const FormatType_toString[] = {
    [JSON] = @"JSON",
    [XML] = @"XML",
    [Atom] = @"Atom",
    [RSS] = @"RSS"
};
...
// To convert enum to string:
NSString *str = FormatType_toString[theEnumValue];

The danger of this approach is that if you ever change the enum, you have to remember to change the array of names. You can solve this problem with some preprocessor abuse, but it's tricky and ugly.

Also note that this assumes you have a valid enum constant. If you have an integer value from an untrusted source, you additionally need to do a check that your constant is valid, e.g. by including a "past max" value in your enum, or by checking if it's less than the array length, sizeof(FormatType_toString) / sizeof(FormatType_toString[0]).

Placing a $ in front of the row value to keep constant worked well for me. e.g.

=b2+a$1

Your userPhotos array is option-typed, you should retrieve the actual underlying object with ! (if you want an error in case the object isn't there) or ? (if you want to receive nil in url):

let userPhotos = currentUser?.photos

for var i = 0; i < userPhotos!.count ; ++i {
    let url = userPhotos![i].url
}

But to preserve safe nil handling, you better use functional approach, for instance, with map, like this:

let urls = userPhotos?.map{ $0.url }

What I do is use Object.keys() to return a list of all the keys and then get the length of that

Object.keys(dictionary).length

path = path.substring(0, path.length() - 5);

To count items after some number of items (offset), $qb->setFirstResults() cannot be applied in this case, as it works not as a condition of query, but as an offset of query result for a range of items selected (i. e. setFirstResult cannot be used togather with COUNT at all). So to count items, which are left I simply did the following:

   //in repository class:
   $count = $qb->select('count(p.id)')
      ->from('Products', 'p')
      ->getQuery()
      ->getSingleScalarResult();

    return $count;

    //in controller class:
    $count = $this->em->getRepository('RepositoryBundle')->...

    return $count-$offset;

Anybody knows more clean way to do it?

First, There is no such css-changes event out of the box, but you can create one by your own, as onchange is for :input elements only. not for css changes.

There are two ways to track css changes.

1. Examine the DOM element for css changes every x time(500 milliseconds in the example).
2. Trigger an event when you change the element css.
3. Use the DOMAttrModified mutation event. But it's deprecated, so I'll skip on it.

First way:

var $element = $("#elementId");
var lastHeight = $("#elementId").css('height');
function checkForChanges()
{
    if ($element.css('height') != lastHeight)
    {
        alert('xxx');
        lastHeight = $element.css('height'); 
    }

    setTimeout(checkForChanges, 500);
}

Second way:

$('#mainContent').bind('heightChange', function(){
        alert('xxx');
    });


$("#btnSample1").click(function() {
    $("#mainContent").css('height', '400px');
    $("#mainContent").trigger('heightChange'); //<====
    ...
});    

If you control the css changes, the second option is a lot more elegant and efficient way of doing it.

Documentations:

• bind: Description: Attach a handler to an event for the elements.
• trigger: Description: Execute all handlers and behaviors attached to the matched elements for the given event type.

For now, use an EditText. Use android:inputType="number" to force it to be numeric. Convert the resulting string into an integer (e.g., Integer.parseInt(myEditText.getText().toString())).

In the future, you might consider a NumberPicker widget, once that becomes available (slated to be in Honeycomb).

Simply:

$(function(){
  $("#my-div").removeClass('hide');
});

Or if you somehow want the class to still be there:

$(function(){
  $("#my-div").css('display', 'block !important');
});

Building of off an earlier example, I think there is a cleaner way of doing this. Create an index.html file in your project and using Stephen's code from above, just convert it into an HTML doc.

<!DOCTYPE html>
<html>
  <base target="_top">
  <script>
    function onSuccess(url) {
      var a = document.createElement("a"); 
      a.href = url;
      a.target = "_blank";
      window.close = function () {
        window.setTimeout(function() {
          google.script.host.close();
        }, 9);
      };
      if (document.createEvent) {
        var event = document.createEvent("MouseEvents");
        if (navigator.userAgent.toLowerCase().indexOf("firefox") > -1) {
          window.document.body.append(a);
        }                        
        event.initEvent("click", true, true); 
        a.dispatchEvent(event);
      } else {
        a.click();
      }
      close();
    }

    function onFailure(url) {
      var div = document.getElementById('failureContent');
      var link = '<a href="' + url + '" target="_blank">Process</a>';
      div.innerHtml = "Failure to open automatically: " + link;
    }

    google.script.run.withSuccessHandler(onSuccess).withFailureHandler(onFailure).getUrl();
  </script>
  <body>
    <div id="failureContent"></div>
  </body>
  <script>
    google.script.host.setHeight(40);
    google.script.host.setWidth(410);
  </script>
</html>

Then, in your Code.gs script, you can have something like the following,

function getUrl() {
  return 'http://whatever.com';
}

function openUrl() {
  var html = HtmlService.createHtmlOutputFromFile("index");
  html.setWidth(90).setHeight(1);
  var ui = SpreadsheetApp.getUi().showModalDialog(html, "Opening ..." );
}

in my case, the method: context.Database.CreateIfNotExists(); called up multiple times before create database and crashed an error A severe error occurred on the current command. The results, if any, should be discarded.

Faster way of writing it would be...

in = open('path/to/input/file').read()
out = open('path/to/input/file', 'w')
replacements = {'zero':'0', 'temp':'bob', 'garbage':'nothing'}
for i in replacements.keys():
    in = in.replace(i, replacements[i])
out.write(in)
out.close

This eliminated a lot of the iterations that the other answers suggest, and will speed up the process for longer files.

You can use the function revalue from the package plyr to replace values in a factor vector.

In your example to replace the factor virginica by setosa:

 data(iris)
 library(plyr)
 revalue(iris$Species, c("virginica" = "setosa")) -> iris$Species

When you perform

>>> [(i) for i in my_list if i=="two"]

i is iterated through the list my_list. As the list comprehension finishes evaluation, i is assigned to the last item in iteration, which is "three".

You can use following command to fix

cat file_name.sh | tr -d '\r' > file_name.sh.new

You (still) can not choose the position of the column using ALTER TABLE: it can only be added to the end of the table. You can obviously select the columns in any order you want, so unless you are using SELECT * FROM column order shouldn't be a big deal.

If you really must have them in a particular order and you can't drop and recreate the table, then you might be able to drop and recreate columns instead:-

First copy the table

CREATE TABLE my_tab_temp AS SELECT * FROM my_tab;

Then drop columns that you want to be after the column you will insert

ALTER TABLE my_tab DROP COLUMN three;

Now add the new column (two in this example) and the ones you removed.

ALTER TABLE my_tab ADD (two NUMBER(2), three NUMBER(10));

Lastly add back the data for the re-created columns

UPDATE my_tab SET my_tab.three = (SELECT my_tab_temp.three FROM my_tab_temp WHERE my_tab.one = my_tab_temp.one);

Obviously your update will most likely be more complex and you'll have to handle indexes and constraints and won't be able to use this in some cases (LOB columns etc). Plus this is a pretty hideous way to do this - but the table will always exist and you'll end up with the columns in a order you want. But does column order really matter that much?

Don't use NULL, C++ allows you to use the unadorned 0 instead:

previous = 0;
next = 0;

And, as at C++11, you generally shouldn't be using either NULL or 0 since it provides you with nullptr of type std::nullptr_t, which is better suited to the task.

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

ArrayList<Customer> custArr = new ArrayList<Customer>();
while(youWantToContinue) {
    //get a customerName
    //get an amount
    custArr.add(new Customer(customerName, amount);
}

For this to work... you'll have to fix your constructor...

Assuming your Customer class has variables called name and sale, your constructor should look like this:

public Customer(String customerName, double amount) {
    name = customerName;
    sale = amount;
}

Change your Store class to something more like this:

public class Store {

    private ArrayList<Customer> custArr;

    public new Store() {
        custArr = new ArrayList<Customer>();
    }

    public void addSale(String customerName, double amount) {
        custArr.add(new Customer(customerName, amount));
    }

    public Customer getSaleAtIndex(int index) {
        return custArr.get(index);
    }

    //or if you want the entire ArrayList:
    public ArrayList getCustArr() {
        return custArr;
    }
}

Your sort logic is wrong. This is the pseudo-code for bubble sort:

for i = 1:n,
    swapped = false
    for j = n:i+1, 
        if a[j] < a[j-1], 
            swap a[j,j-1]
            swapped = true
    ? invariant: a[1..i] in final position
    break if not swapped
end

See this sorting web site for good tutorial on all the various sorting methods.

I solved this with one code line, as follow: In file index.php, at your template root, after this code line:

defined( '_JEXEC' ) or die( 'Restricted access' );

paste this line: ini_set ('display_errors', 'Off');

Don't worry, be happy...

The methods Calendar.getTimeInMillis() and Date.getTime() both return milliseconds since 1.1.1970.

For current time, you can use:

long seconds = System.currentTimeMillis() / 1000l;

just call your function inside the events.

load:

$(document).ready(function(){  // or  $(window).load(function(){
    topInViewport($(mydivname));
});

resize:

$(window).resize(function () {
    topInViewport($(mydivname));
});

scroll:

$(window).scroll(function () {
    topInViewport($(mydivname));
});

or bind all event in one function

$(window).on("load scroll resize",function(e){

You have configured the auth.php and used members table for authentication but there is no user_email field in the members table so, Laravel says

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_email' in 'where clause' (SQL: select * from members where user_email = ? limit 1) (Bindings: array ( 0 => '[email protected]', ))

Because, it tries to match the user_email in the members table and it's not there. According to your auth configuration, laravel is using members table for authentication not users table.

You can make use of in_array() in PHP.

$os = array("uk", "us"); // You can set multiple check conditions here
if (in_array("uk", $os)) //Founds a match !
{
    echo "Got you"; 
}

If you want to just check if they are identical or not, a == b should give you true / false with ordering taken into account.

In case you want to compare elements, you can use numpy for comparison

c = (numpy.array(a) == numpy.array(b))

Here, c will contain an array with 3 elements all of which are true (for your example). In the event elements of a and b don't match, then the corresponding elements in c will be false.

You can use JSON.stringify(object) with an object and I just wrote a function that'll recursively convert an array to an object, like this JSON.stringify(convArrToObj(array)), which is the following code (more detail can be found on this answer):

// Convert array to object
var convArrToObj = function(array){
    var thisEleObj = new Object();
    if(typeof array == "object"){
        for(var i in array){
            var thisEle = convArrToObj(array[i]);
            thisEleObj[i] = thisEle;
        }
    }else {
        thisEleObj = array;
    }
    return thisEleObj;
}

To make it more generic, you can override the JSON.stringify function and you won't have to worry about it again, to do this, just paste this at the top of your page:

// Modify JSON.stringify to allow recursive and single-level arrays
(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        return oldJSONStringify(convArrToObj(input));
    };
})();

And now JSON.stringify will accept arrays or objects! (link to jsFiddle with example)

Edit:

Here's another version that's a tad bit more efficient, although it may or may not be less reliable (not sure -- it depends on if JSON.stringify(array) always returns [], which I don't see much reason why it wouldn't, so this function should be better as it does a little less work when you use JSON.stringify with an object):

(function(){
    // Convert array to object
    var convArrToObj = function(array){
        var thisEleObj = new Object();
        if(typeof array == "object"){
            for(var i in array){
                var thisEle = convArrToObj(array[i]);
                thisEleObj[i] = thisEle;
            }
        }else {
            thisEleObj = array;
        }
        return thisEleObj;
    };
    var oldJSONStringify = JSON.stringify;
    JSON.stringify = function(input){
        if(oldJSONStringify(input) == '[]')
            return oldJSONStringify(convArrToObj(input));
        else
            return oldJSONStringify(input);
    };
})();

My solution not using jQuery (because sometimes they don't have to be the same thing) is below. Though it was only tested in Internet Explorer 7, so the community can point out all the reasons this is wrong:

textarea.onkeyup = function () { this.style.height = this.scrollHeight + 'px'; }

So far I really like how it's working, and I don't care about other browsers, so I'll probably apply it to all my textareas:

// Make all textareas auto-resize vertically
var textareas = document.getElementsByTagName('textarea');

for (i = 0; i<textareas.length; i++)
{
    // Retain textarea's starting height as its minimum height
    textareas[i].minHeight = textareas[i].offsetHeight;

    textareas[i].onkeyup = function () {
        this.style.height = Math.max(this.scrollHeight, this.minHeight) + 'px';
    }
    textareas[i].onkeyup(); // Trigger once to set initial height
}

With the new Add-Ons for Google Drive, you can get code highlighting with the Code Pretty add-on.

I compiled and run my code. This is accurate code. You can try it your own.

data = pd.read_excel('file.xlsx')

If you have any special character or space in column name you can write it in '' like in the given code:

data = data[data['expire/t'].notnull()]
print (date)

If there is just a single string column name without any space or special character you can directly access it.

data = data[data.expire ! = 0]
print (date)

You can close files not csv.writer object, it should be:

f = open(fileName, "wb")
writer = csv.writer(f)
String[] entries = "first*second*third".split("*");
writer.writerows(entries)
f.close()

You can't downcast. If the parent object is created, it cannot be cast to the child.

One suggested workaround would be to Create an interface which the parent implements. Have the child override functionality if needed or just expose the parents functionality. Change the cast to be an interface and do the operations.

Edit: May be could also check if the object is a SkyfilterClient using is keyword

   if(networkClient is SkyfilterClient)
   {

   }

Although the solution you referred to uses jquery, mouseenter and mouseleave are native dom events, so you might use without jquery.

you can put everything in a block and easily write any code that you wish in that block just exactly the below code :

@{
        bool isUserConnected = string.IsNullOrEmpty(Model.CreatorFullName);
        if (isUserConnected)
        { // meaning that the viewing user has not been saved
            <div>
                <div> click to join us </div>
                <a id="login" href="javascript:void(0);" style="display: inline; ">join</a>
            </div>
        }
    }

it helps you to have at first a cleaner code and also you can prevent your page from loading many times different blocks of codes

As usual, VBScript is available for you to use.....

Set objFS = CreateObject("Scripting.FileSystemObject")
Set wshArgs = WScript.Arguments
strFile = wshArgs(0)
WScript.Echo objFS.GetFile(strFile).Size & " bytes"

Save as filesize.vbs and enter on the command-line:

C:\test>cscript /nologo filesize.vbs file.txt
79 bytes

Use a for loop (in batch) to get the return result.

You can alternatively use php54w or php55w if required.

This may potentially break your website if it doesn't fully resolve all your dependencies, so you may need a couple of extra packages in some cases. See here for a list of other PHP 5.6 modules that are available.

If you encounter a problem and need to reset back to the default, you can use these commands:

sudo yum remove php56w
sudo yum remove php56w-common
sudo yum install php-common
sudo yum install php-mysql
sudo yum install php

Here is a bash script inspired by abarnert's answer which will unpack a package named MyPackage.pkg into a subfolder named MyPackage_pkg and then open the folder in Finder.

    #!/usr/bin/env bash
    filename="$*"
    dirname="${filename/\./_}"
    pkgutil --expand "$filename" "$dirname"
    cd "$dirname"
    tar xvf Payload
    open .

Usage:

    pkg-upack.sh MyPackage.pkg

Warning: This will not work in all cases, and will fail with certain files, e.g. the PKGs inside the OSX system installer. If you want to peek inside the pkg file and see what's inside, you can try SuspiciousPackage (free app), and if you need more options such as selectively unpacking specific files, then have a look at Pacifist (nagware).

I introduce a Bindable class in my blog at http://timoch.com/blog/2013/08/annoyed-with-inotifypropertychange/ Bindable uses a dictionary as a property bag. It's easy enough to add the necessary overloads for a subclass to manage its own backing field using ref parameters.

• No magic string
• No reflection
• Can be improved to suppress the default dictionary lookup

The code:

public class Bindable : INotifyPropertyChanged {
    private Dictionary<string, object> _properties = new Dictionary<string, object>();

    /// <summary>
    /// Gets the value of a property
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="name"></param>
    /// <returns></returns>
    protected T Get<T>([CallerMemberName] string name = null) {
        Debug.Assert(name != null, "name != null");
        object value = null;
        if (_properties.TryGetValue(name, out value))
            return value == null ? default(T) : (T)value;
        return default(T);
    }

    /// <summary>
    /// Sets the value of a property
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="value"></param>
    /// <param name="name"></param>
    /// <remarks>Use this overload when implicitly naming the property</remarks>
    protected void Set<T>(T value, [CallerMemberName] string name = null) {
        Debug.Assert(name != null, "name != null");
        if (Equals(value, Get<T>(name)))
            return;
        _properties[name] = value;
        OnPropertyChanged(name);
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null) {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null) {
            handler(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

It can be used like this:

public class Contact : Bindable {
    public string FirstName {
        get { return Get<string>(); }
        set { Set(value); }
    }
}

I had problems with using the getClass().getResource("filename.txt") method. Upon reading the Java docs instructions, if your resource is not in the same package as the class you are trying to access the resource from, then you have to give it relative path starting with '/'. The recommended strategy is to put your resource files under a "resources" folder in the root directory. So for example if you have the structure:

src/main/com/mycompany/myapp

then you can add a resources folder as recommended by maven in:

src/main/resources

furthermore you can add subfolders in the resources folder

src/main/resources/textfiles

and say that your file is called myfile.txt so you have

src/main/resources/textfiles/myfile.txt

Now here is where the stupid path problem comes in. Say you have a class in your com.mycompany.myapp package, and you want to access the myfile.txt file from your resource folder. Some say you need to give the:

"/main/resources/textfiles/myfile.txt" path

or

"/resources/textfiles/myfile.txt"

both of these are wrong. After I ran mvn clean compile, the files and folders are copied in the:

myapp/target/classes 

folder. But the resources folder is not there, just the folders in the resources folder. So you have:

myapp/target/classes/textfiles/myfile.txt

myapp/target/classes/com/mycompany/myapp/*

so the correct path to give to the getClass().getResource("") method is:

"/textfiles/myfile.txt"

here it is:

getClass().getResource("/textfiles/myfile.txt")

This will no longer return null, but will return your class. I hope this helps somebody. It is strange to me, that the "resources" folder is not copied as well, but only the subfolders and files directly in the "resources" folder. It would seem logical to me that the "resources" folder would also be found under "myapp/target/classes"

Make sure of the conflict origin: if it is the result of a git merge, see Brian Campbell's answer.

But if is the result of a git rebase, in order to discard remote (their) changes and use local changes, you would have to do a:

git checkout --theirs -- .

See "Why is the meaning of “ours” and “theirs” reversed"" to see how ours and theirs are swapped during a rebase (because the upstream branch is checked out).

According to this article, you may try following command:

   ssh-add -l

If your key isn't in the list, then

   ssh-add /var/lib/jenkins/.ssh/id_rsa_project

Well previously, I used the approach that you can find inside the WebElement:

WebElement baseTable = driver.findElement(By.tagName("table"));
WebElement tableRow = baseTable.findElement(By.xpath("//tr[2]")); //should be the third row
webElement cellIneed = tableRow.findElement(By.xpath("//td[2]"));
String valueIneed = cellIneed.getText();

Please note that I find inside the found WebElement instance.

The above is Java code, assuming that driver variable is healthy instance of WebDriver

In short: It's a shorthand notation for a mathematical hack.

Long explanation:

You can't do a cross product with vectors in 2D space. The operation is not defined there.

However, often it is interesting to evaluate the cross product of two vectors assuming that the 2D vectors are extended to 3D by setting their z-coordinate to zero. This is the same as working with 3D vectors on the xy-plane.

If you extend the vectors that way and calculate the cross product of such an extended vector pair you'll notice that only the z-component has a meaningful value: x and y will always be zero.

That's the reason why the z-component of the result is often simply returned as a scalar. This scalar can for example be used to find the winding of three points in 2D space.

From a pure mathematical point of view the cross product in 2D space does not exist, the scalar version is the hack and a 2D cross product that returns a 2D vector makes no sense at all.

Query with sub query in Laravel

$resortData = DB::table('resort')
        ->leftJoin('country', 'resort.country', '=', 'country.id')
        ->leftJoin('states', 'resort.state', '=', 'states.id')
        ->leftJoin('city', 'resort.city', '=', 'city.id')
        ->select('resort.*', 'country.name as country_name', 'states.name as state_name','city.name as city_name', DB::raw("(SELECT GROUP_CONCAT(amenities.name) from resort_amenities LEFT JOIN amenities on amenities.id= resort_amenities.amenities_id WHERE resort_amenities.resort_id=resort.id) as amenities_name"))->groupBy('resort.id')
        ->orderBy('resort.id', 'DESC')
       ->get();

Same thing happened to me. Eventually my solution was to navigate to the repository using terminal (on mac) and create a new js file with a slightly different name. It linked immediately so i copied contents of original file to new one. You also might want to lose the first / after src= and use "".

I came under the same problem with R. I dig a bit and come with a solution, that we need to restart R session to fully clean the memory/RAM. For this, you can use a simple code after removing everything from your workspace. the code is as follows :

rm(list = ls())

.rs.restartR()

Try these two things separately and together:

1. remove the if($_POST['submit']){}
2. remove $from (just my gut)

Open terminal emulator on the phone: then

adb shell

after that daemon is started

su
mount -o rw,remount /mnt/sdcard

then the read only is converted into the read-Write.

I know this is an old post, but another simple option is using the INPUT TYPE="FILE" tag according to compatibility most major browser support this feature.

I think that your problem is actually with not correctly indenting init function.It should be like this

class MyClass():
     def __init__(self, filename):
          pass

     def parse_file():
          pass

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

To print keys on one line as csv:

echo '{"b":"2","a":"1"}' | jq -r 'keys | [ .[] | tostring ] | @csv'

Output:

"a","b"

For csv completeness ... to print values on one line as csv:

echo '{"b":"2","a":"1"}' | jq -rS . | jq -r '. | [ .[] | tostring ] | @csv'

Output:

"1","2"

please don't try with the old cv module, use cv2:

import cv2

cv2.rectangle(img, (x1, y1), (x2, y2), (255,0,0), 2)


x1,y1 ------
|          |
|          |
|          |
--------x2,y2

[edit] to append the follow-up questions below:

cv2.imwrite("my.png",img)

cv2.imshow("lalala", img)
k = cv2.waitKey(0) # 0==wait forever

I did re-import all maven projects. This worked for me.

On my part, what trigger this error was that I had, at the root of my resources folder, a folder with the same name as my final executable file.

So, when launching the executable, I think Xcode found the folder and had problem executing a folder! ;-)

Do git help gitignore

You will get the help page with following line:

A line starting with # serves as a comment.

Right click in the query pane, select Query Options... and in the Execution->General section (the default when you first open it) there is an Execution time-out setting.

I just add this line of code into onCreate():

this.getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

Problem solved.

I know this is an old answer but here is what I usually do:

CSS:

.form-control-inline {
   width: auto;
   float:left;
   margin-right: 5px;
}

Then wrap the fields you want to be inlined in a div and add .form-control-inline to the input, example:

HTML

<label class="control-label">Date of birth:</label>
<div>
<select class="form-control form-control-inline" name="year"> ... </select>
<select class="form-control form-control-inline" name="month"> ... </select>
<select class="form-control form-control-inline" name="day"> ... </select>
</div>

Using jQuery:

$('#play-pause').click(function(){
  if ( $('#video-over').css('visibility') == 'hidden' )
    $('#video-over').css('visibility','visible');
  else
    $('#video-over').css('visibility','hidden');
});

There is a danger with using the <input type="text" pattern="\d*"> to bring up the numeric keyboard. On firefox and chrome, the regular expression contained within the pattern causes the browser to validate the input to that expression. errors will occur if it doesn't match the pattern or is left blank. Be aware of unintended actions in other browsers.

Along with making sure you install the 64bit version, also check to make sure that the symbolic link of '/usr/local/mysql' is pointing to the correct version of your installation:

lrwxr-xr-x   1 root  wheel    27B Aug 29 01:24 mysql -> mysql-5.1.37-osx10.5-x86_64
drwxr-xr-x   3 root  wheel   102B Aug 29 01:25 mysql-5.1.30-osx10.5-x86
drwxr-xr-x  11 root  wheel   374B Aug 29 15:59 mysql-5.1.37-osx10.5-x86_64
drwxr-xr-x  17 root  wheel   578B Jul 13 22:06 mysql-5.1.37-osx10.5-x86_64.old

Alos, I found that after my installation, even though I used the pkg file from MySQL various other libraries would not build against the installation. The solution was to follow the steps to build MySQL from source found here. You can manually start it as root with the command:

/usr/loca/mysql/bin/mysqld_safe [whatever options you use]

Now ... to get the preference pane working I did the following:

1. Installed 64bit version of MySQL Server packet from mysql.com
2. Moved the package from mysql-5.1.37-osx10.5-x86_64 to mysql-5.1.37-osx10.5-x86_64.old
3. Did a manual compile and installation of MySQL as per these instructions

4. Executed the following command:

   sudo cp -R /usr/local/mysql-5.1.37-osx10.5-x86_64.old/support-files /usr/local/mysql/.

5. Opened up the MySQL Preference Pane and tada! it works

Also $( "#container" ).find( "div.robotarm" );
is equal to: $( "div.robotarm", "#container" )

I found cascading it works great for multibrowser detection.

This code was used to change a fade to show/hide in ie 8 7 6.

$(document).ready(function(){
    if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 8.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         { if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 7.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         {if(jQuery.browser.msie && jQuery.browser.version.substring(0, 1) == 6.0)
         { 
             $(".glow").hide();
            $('#shop').hover(function() {
        $(".glow").show();
    }, function() {
        $(".glow").hide();
    });
         }
         else
         { $('#shop').hover(function() {
        $(".glow").stop(true).fadeTo("400ms", 1);
    }, function() {
        $(".glow").stop(true).fadeTo("400ms", 0.2);});
         }
         }
         }
       });

Briefly:

1. Get the self signed certificate
2. Put it into some (e.g. ~/git-certs/cert.pem) file
3. Set git to trust this certificate using http.sslCAInfo parameter

In more details:

Get self signed certificate of remote server

Assuming, the server URL is repos.sample.com and you want to access it over port 443.

There are multiple options, how to get it.

Get certificate using openssl

$ openssl s_client -connect repos.sample.com:443

Catch the output into a file cert.pem and delete all but part between (and including) -BEGIN CERTIFICATE- and -END CERTIFICATE-

Content of resulting file ~/git-certs/cert.pem may look like this:

-----BEGIN CERTIFICATE-----

Get certificate using your web browser

I use Redmine with Git repositories and I access the same URL for web UI and for git command line access. This way, I had to add exception for that domain into my web browser.

Using Firefox, I went to Options -> Advanced -> Certificates -> View Certificates -> Servers, found there the selfsigned host, selected it and using Export button I got exactly the same file, as created using openssl.

Note: I was a bit surprised, there is no name of the authority visibly mentioned. This is fine.

Having the trusted certificate in dedicated file

Previous steps shall result in having the certificate in some file. It does not matter, what file it is as long as it is visible to your git when accessing that domain. I used ~/git-certs/cert.pem

Note: If you need more trusted selfsigned certificates, put them into the same file:

-----BEGIN CERTIFICATE-----
MIIDnzCCAocCBE/xnXAwDQYJKoZIhvcNAQEFBQAwgZMxCzAJBgNVBAYTAkRFMRUw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
AnOtHeRtRuStEdCeRtIfIcAtEgOeShErExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----

This shall work (but I tested it only with single certificate).

Configure git to trust this certificate

$ git config --global http.sslCAInfo /home/javl/git-certs/cert.pem

You may also try to do that system wide, using --system instead of --global.

And test it: You shall now be able communicating with your server without resorting to:

$ git config --global http.sslVerify false #NO NEED TO USE THIS

If you already set your git to ignorance of ssl certificates, unset it:

$ git config --global --unset http.sslVerify

and you may also check, that you did it all correctly, without spelling errors:

$ git config --global --list

what should list all variables, you have set globally. (I mispelled http to htt).

The core of your problem seems to be matching the columns in the CSV file to those in the table.

Many graphical mySQL clients have very nice import dialogs for this kind of thing.

My favourite for the job is Windows based HeidiSQL. It gives you a graphical interface to build the LOAD DATA command; you can re-use it programmatically later.

Screenshot: "Import textfile" dialog

To open the Import textfile" dialog, go to Tools > Import CSV file:

Use preventDefault() to stop the event of submit button and in ajax call success submit the form using submit():

$('#btnSave').click(function (e) {
    e.preventDefault(); // <------------------ stop default behaviour of button
    var element = this;    
    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {
            if (data.status == "Success") {
                alert("Done");
                $(element).closest("form").submit(); //<------------ submit form
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

In order to match a digit, you can use [0-9].

So you could use 5[0-9][0-9][0-9][0-9][0-9][0-9] and [0-9][0-9][0-9][0-9]7[0-9][0-9][0-9]. I do this a lot for zip codes.

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

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

list.Add(cul.DisplayName, cod);

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

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

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

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

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

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

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

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

To safely encrypt large files (>600MB) with openssl smime you'll have to split each file into small chunks:

# Splits large file into 500MB pieces
split -b 500M -d -a 4 INPUT_FILE_NAME input.part.

# Encrypts each piece
find -maxdepth 1 -type f -name 'input.part.*' | sort | xargs -I % openssl smime -encrypt -binary -aes-256-cbc -in % -out %.enc -outform DER PUBLIC_PEM_FILE

For the sake of information, here is how to decrypt and put all pieces together:

# Decrypts each piece
find -maxdepth 1 -type f -name 'input.part.*.enc' | sort | xargs -I % openssl smime -decrypt -in % -binary -inform DEM -inkey PRIVATE_PEM_FILE -out %.dec

# Puts all together again

Even if you capture the keydown/keyup event, those are the only events that the tab key fires, you still need some way to prevent the default action, moving to the next item in the tab order, from occurring.

In Firefox you can call the preventDefault() method on the event object passed to your event handler. In IE, you have to return false from the event handle. The JQuery library provides a preventDefault method on its event object that works in IE and FF.

<body>
<input type="text" id="myInput">
<script type="text/javascript">
    var myInput = document.getElementById("myInput");
    if(myInput.addEventListener ) {
        myInput.addEventListener('keydown',this.keyHandler,false);
    } else if(myInput.attachEvent ) {
        myInput.attachEvent('onkeydown',this.keyHandler); /* damn IE hack */
    }

    function keyHandler(e) {
        var TABKEY = 9;
        if(e.keyCode == TABKEY) {
            this.value += "    ";
            if(e.preventDefault) {
                e.preventDefault();
            }
            return false;
        }
    }
</script>
</body>

I ran into the same problem as you. I wanted to make a DIV as background, why, because its easy to manipulate div through javascript. Anyways three things I did in the css for that div.

CSS:

{    
position:absolute; 
display:block; 
height:100%; 
width:100%; 
top:0px; 
left:0px; 
z-index:-1;    
}

^dbo\..*_fn$

This should work you.

Set the KeyPreview attribute on your form to True, then use the KeyPress event at your form level to detect the Enter key. On detection call whatever code you would have for the "submit" button.

I think this is easy way to drop the index.

set FOREIGN_KEY_CHECKS=0; //disable checks

ALTER TABLE mytable DROP INDEX AID;

set FOREIGN_KEY_CHECKS=1; //enable checks

I answered a very similar question:

https://stackoverflow.com/a/15982217/1467082

You simply need to iterate over the series' .Points collection, and then you can assign the points' .Format.Fill.ForeColor.RGB value based on whatever criteria you need.

UPDATED

The code below will color the chart per the screenshot. This only assumes three colors are used. You can add additional case statements for other color values, and update the assignment of myColor to the appropriate RGB values for each.

Option Explicit
Sub ColorScatterPoints()
    Dim cht As Chart
    Dim srs As Series
    Dim pt As Point
    Dim p As Long
    Dim Vals$, lTrim#, rTrim#
    Dim valRange As Range, cl As Range
    Dim myColor As Long

    Set cht = ActiveSheet.ChartObjects(1).Chart
    Set srs = cht.SeriesCollection(1)

   '## Get the series Y-Values range address:
    lTrim = InStrRev(srs.Formula, ",", InStrRev(srs.Formula, ",") - 1, vbBinaryCompare) + 1
    rTrim = InStrRev(srs.Formula, ",")
    Vals = Mid(srs.Formula, lTrim, rTrim - lTrim)
    Set valRange = Range(Vals)

    For p = 1 To srs.Points.Count
        Set pt = srs.Points(p)
        Set cl = valRange(p).Offset(0, 1) '## assume color is in the next column.

        With pt.Format.Fill
            .Visible = msoTrue
            '.Solid  'I commented this out, but you can un-comment and it should still work
            '## Assign Long color value based on the cell value
            '## Add additional cases as needed.
            Select Case LCase(cl)
                Case "red"
                    myColor = RGB(255, 0, 0)
                Case "orange"
                    myColor = RGB(255, 192, 0)
                Case "green"
                    myColor = RGB(0, 255, 0)
            End Select

            .ForeColor.RGB = myColor

        End With
    Next

If you want to play with the thread stack size, you'll want to look at the -Xss option on the Hotspot JVM. It may be something different on non Hotspot VM's since the -X parameters to the JVM are distribution specific, IIRC.

On Hotspot, this looks like java -Xss16M if you want to make the size 16 megs.

Type java -X -help if you want to see all of the distribution specific JVM parameters you can pass in. I am not sure if this works the same on other JVMs, but it prints all of Hotspot specific parameters.

For what it's worth - I would recommend limiting your use of recursive methods in Java. It's not too great at optimizing them - for one the JVM doesn't support tail recursion (see Does the JVM prevent tail call optimizations?). Try refactoring your factorial code above to use a while loop instead of recursive method calls.

r for read

w for write

r+ for read/write without deleting the original content if file exists, otherwise raise exception

w+ for delete the original content then read/write if file exists, otherwise create the file

For example,

>>> with open("file1.txt", "w") as f:
...   f.write("ab\n")
... 
>>> with open("file1.txt", "w+") as f:
...   f.write("c")
... 

$ cat file1.txt 
c$

>>> with open("file2.txt", "r+") as f:
...   f.write("ab\n")
... 
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
IOError: [Errno 2] No such file or directory: 'file2.txt'

>>> with open("file2.txt", "w") as f:
...   f.write("ab\n")
... 
>>> with open("file2.txt", "r+") as f:
...   f.write("c")
... 

$ cat file2.txt 
cb
$

Using encodeURIComponent():

var url = 'index.php?data='+encodeURIComponent(JSON.stringify({"json":[{"j":"son"}]})),

You can use as below:

GlobalConfiguration.Configuration.Formatters.Clear();
GlobalConfiguration.Configuration.Formatters.Add(new JsonMediaTypeFormatter());

I would do the same as Kumu

namespace ExtensionMethods
{
    public static class MyExtensionMethods
    {
        public static DateTime Tomorrow(this DateTime date)
        {
           return date.AddDays(1);
        }    
    }
}

but call it like this new DateTime().Tomorrow();

Think it makes more seens than DateTime.Now.Tomorrow();

if you want to install a PHP version < 5.3.0, you must replace

--enable-cgi

with:

--enable-fastcgi

in your ./configure statement, excerpt from the php.net doc:

--enable-fastcgi

If this is enabled, the CGI module will be built with support for FastCGI also. Available since PHP 4.3.0

As of PHP 5.3.0 this argument no longer exists and is enabled by --enable-cgi instead. After the compilation the ./php-cgi -v should look like this:

PHP 5.2.17 (cgi-fcgi) (built: Jul  9 2013 18:28:12)
Copyright (c) 1997-2010 The PHP Group
Zend Engine v2.2.0, Copyright (c) 1998-2010 Zend Technologies

NOTICE THE (cgi-fcgi)

Try:

pwd=`pwd`

or

pwd=$(pwd)

Notice no spaces after the equals sign.

Also as Mr. Weiss points out; you don't assign to $pwd, you assign to pwd.

As others have stated it's combination of your schema and the number of indexes.

A friend had about 100,000,000 historical stock prices, daily closing quotes, in an MDB which approached the 2 Gb limit.

He pulled them down using some code found in a Microsoft Knowledge base article. I was rather surprised that whatever server he was using didn't cut him off after the first 100K records.

He could view any record in under a second.

If you use FastCGI try:

fastcgi_hide_header X-Powered-By;

A slightly prettier function based on Ansgar Wiechers's answer. Whether it's actually more useful is a matter of debate.

function Read-Choice(
   [Parameter(Mandatory)][string]$Message,
   [Parameter(Mandatory)][string[]]$Choices,
   [Parameter(Mandatory)][string]$DefaultChoice,
   [Parameter()][string]$Question='Are you sure you want to proceed?'
) {
    $defaultIndex = $Choices.IndexOf($DefaultChoice)
    if ($defaultIndex -lt 0) {
        throw "$DefaultChoice not found in choices"
    }

    $choiceObj = New-Object Collections.ObjectModel.Collection[Management.Automation.Host.ChoiceDescription]

    foreach($c in $Choices) {
        $choiceObj.Add((New-Object Management.Automation.Host.ChoiceDescription -ArgumentList $c))
    }

    $decision = $Host.UI.PromptForChoice($Message, $Question, $choiceObj, $defaultIndex)
    return $Choices[$decision]
}

Example usage:

PS> $r = Read-Choice 'DANGER!!!!!!' '&apple','&blah','&car' '&blah'

DANGER!!!!!!
Are you sure you want to proceed?
[A] apple  [B] blah  [C] car  [?] Help (default is "B"): c
PS> switch($r) { '&car' { Write-host 'caaaaars!!!!' } '&blah' { Write-Host "It's a blah day" } '&apple' { Write-Host "I'd like to eat some apples!" } }
caaaaars!!!!

Run Visual Studio as Administrator

I ran into a similar problem. It works on one server and does not on another server with same Nginx configuration. Found the the solution which is answered by Igor here http://forum.nginx.org/read.php?2,1612,1627#msg-1627

Yes. Or you may combine SSL/non-SSL servers in one server:

server {
  listen 80;
  listen 443 default ssl;

  # ssl on   - remember to comment this out

}

As @Alex McMillan mentioned, use state to dictate what should be rendered in the dom.

In the example below I have an input field and I want to add a second one when the user clicks the button, the onClick event handler calls handleAddSecondInput( ) which changes inputLinkClicked to true. I am using a ternary operator to check for the truthy state, which renders the second input field

class HealthConditions extends React.Component {
  constructor(props) {
    super(props);


    this.state = {
      inputLinkClicked: false
    }
  }

  handleAddSecondInput() {
    this.setState({
      inputLinkClicked: true
    })
  }


  render() {
    return(
      <main id="wrapper" className="" data-reset-cookie-tab>
        <div id="content" role="main">
          <div className="inner-block">

            <H1Heading title="Tell us about any disabilities, illnesses or ongoing conditions"/>

            <InputField label="Name of condition"
              InputType="text"
              InputId="id-condition"
              InputName="condition"
            />

            {
              this.state.inputLinkClicked?

              <InputField label=""
                InputType="text"
                InputId="id-condition2"
                InputName="condition2"
              />

              :

              <div></div>
            }

            <button
              type="button"
              className="make-button-link"
              data-add-button=""
              href="#"
              onClick={this.handleAddSecondInput}
            >
              Add a condition
            </button>

            <FormButton buttonLabel="Next"
              handleSubmit={this.handleSubmit}
              linkto={
                this.state.illnessOrDisability === 'true' ?
                "/404"
                :
                "/add-your-details"
              }
            />

            <BackLink backLink="/add-your-details" />

          </div>
         </div>
      </main>
    );
  }
}

All or perhaps most of the answers in this question and in other questions on SO relating to GET and POST are misguided. They are technically correct and they explain the standards correctly, but in practice it's completely different. Let me explain:

GET is considered to be idempotent, but it doesn't have to be. You can pass parameters in a GET to a server script that makes permanent changes to data. Conversely, POST is considered not idempotent, but you can POST to a script that makes no changes to the server. So this is a false dichotomy and irrelevant in practice.

Further, it is a mistake to say that GET cannot harm anything if reloaded - of course it can if the script it calls and the parameters it passes are making a permanent change (like deleting data for examples). And so can POST!

Now, we know that POST is (by far) more secure because it doesn't expose the parameters being passed, and it is not cached. Plus you can pass more data and you GET a clean, non-confusing URL. And it does everything that GET can do. So it is simply better. At least in production.

So in practice, when should you use GET vs. POST? I use GET during development so I can see and tweak the parameters I am passing. I use it to quickly try different values (to test conditions for example) or even different parameters. I can do that without having to build a form and having to modify it if I need a different set of parameters. I simply edit the URL in my browser as needed.

Once development is done, or at least stable, I switch everything to POST.

If you can think of any technical reason that this is incorrect, I would be very happy to learn.

I'm going to answer this myself.

I've determined that there is a difference. "git fetch --tags" might bring in all the tags, but it doesn't bring in any new commits!

Turns out one has to do this to be totally "up to date", i.e. replicated a "git pull" without the merge:

$ git fetch --tags
$ git fetch

This is a shame, because it's twice as slow. If only "git fetch" had an option to do what it normally does and bring in all the tags.

It's a Python version problem. If you are using the latest, then your old syntax won't work and give you this error. Please follow @Josav09's code and you will be fine.

push does not return the array, but the length of it (docs), so what you are doing is replacing the array with its length, losing the only reference to it that you had. Try this:

import {ADD_ITEM} from '../Actions/UserActions'
const initialUserState = {

    arr:[]
}

export default function userState(state = initialUserState, action){
     console.log(arr);
     switch (action.type){
        case ADD_ITEM :
          return { 
             ...state,
             arr:[...state.arr, action.newItem]
        }

        default:return state
     }
}

Update database and Set fieldName=Replace (fieldName,'FindString','ReplaceString')

FYI: Numeric field size violations will give ORA-01438: value larger than specified precision allowed for this column

VARCHAR2 field length violations will give ORA-12899: value too large for column...

Oracle makes a distinction between the data types of the column based on the error code and message.

I found this topic while searching for run script for startup and shutdown Windows 10. Those answers above didn't working. For me on windows 10 worked when I put scripts to task scheduler. How to do this: press window key and write Task scheduler, open it, then on the right is Add task... button. Here you can add scripts. PS: I found action for startup and logout user, there is not for shutdown.

For what I know printing the complete stack trace in nodejs is not possible, you can just print a "partial" stack trace, you can not see from where you came from in the code, just where the Exception occur. That's what Ryan Dahl explains in this youtube video. http://youtu.be/jo_B4LTHi3I at min 56:30 for being precise. Hope this helps

In the "database" section of the logon dialog box, enter //hostname.domain:port/database, in your case //123.45.67.89:1521/TEST - this assumes that you don't want to set up a tnsnames.ora file/entry for some reason.

Also make sure the firewall settings on your server are not blocking port 1521.

The other answers will work for most strings, but you can end up unescaping an already escaped double quote, which is probably not what you want.

To work correctly, you are going to need to escape all backslashes and then escape all double quotes, like this:

var test_str = '"first \\" middle \\" last "';
var result = test_str.replace(/\\/g, '\\\\').replace(/\"/g, '\\"');

depending on how you need to use the string, and the other escaped charaters involved, this may still have some issues, but I think it will probably work in most cases.

Maybe you want maven-shade-plugin, bundle dependencies, minimize unused code and hide external dependencies to avoid conflicts.

I think this code will do what you want. It stores the first row as a set of headers, then stores the rest in a data object which you can write to disk as JSON.

var XLSX = require('xlsx');
var workbook = XLSX.readFile('test.xlsx');
var sheet_name_list = workbook.SheetNames;
sheet_name_list.forEach(function(y) {
    var worksheet = workbook.Sheets[y];
    var headers = {};
    var data = [];
    for(z in worksheet) {
        if(z[0] === '!') continue;
        //parse out the column, row, and value
        var col = z.substring(0,1);
        var row = parseInt(z.substring(1));
        var value = worksheet[z].v;

        //store header names
        if(row == 1) {
            headers[col] = value;
            continue;
        }

        if(!data[row]) data[row]={};
        data[row][headers[col]] = value;
    }
    //drop those first two rows which are empty
    data.shift();
    data.shift();
    console.log(data);
});

prints out
