Short answer. No. Eclipse does not have a command line switch like Visual Studio to build a project.

System.Data.SqlClient is the .NET Framework Data Provider for SQL Server. ie .NET library for SQL Server.

I don't know where providerName=SqlServer comes from. Could you be getting this confused with the provider keyword in your connection string? (I know I was :) )

In the web.config you should have the System.Data.SqlClient as the value of the providerName attribute. It is the .NET Framework Data Provider you are using.

<connectionStrings>
   <add 
      name="LocalSqlServer" 
      connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" 
      providerName="System.Data.SqlClient"
   />
</connectionStrings>

Step 1: Add the bean class into the dataFormat list:

<dataFormats>
    <json id="jack" library="Jackson" prettyPrint="true"
          unmarshalTypeName="{ur bean class path}" /> 
</dataFormats>

Step 2: Marshal the bean prior to the client call:

<marchal id="marsh" ref="jack"/>

For me, installing development version of libyaml did it.

yum install libyaml-devel         #centos
apt-get install libyaml-dev       # ubuntu

To complement @Joe's answer:

Hamcrest provides you with three main methods to match a list:

contains Checks for matching all the elements taking in count the order, if the list has more or less elements, it will fail

containsInAnyOrder Checks for matching all the elements and it doesn't matter the order, if the list has more or less elements, will fail

hasItems Checks just for the specified objects it doesn't matter if the list has more

hasItem Checks just for one object it doesn't matter if the list has more

All of them can receive a list of objects and use equals method for comparation or can be mixed with other matchers like @borjab mentioned:

assertThat(myList , contains(allOf(hasProperty("id", is(7L)), 
                                   hasProperty("name", is("testName1")),
                                   hasProperty("description", is("testDesc1"))),
                             allOf(hasProperty("id", is(11L)), 
                                   hasProperty("name", is("testName2")),
                                   hasProperty("description", is("testDesc2")))));

svn log -r {2009-09-17}:HEAD

where 2009-09-17 is the date you went on holiday. To see the changed files as well as the summary, add a -v option:

svn log -r {2009-09-17}:HEAD -v

I haven't used WebSVN but there will be a log viewer somewhere that does the equivalent of these commands under the hood.

You were almost there:

You just need to append the li to ul and voila!

So just add

ul.appendChild(li);

to the end of your function so the end function will be like this:

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Element 4"));
  ul.appendChild(li);
}

Here is an example for MySQL for looping through a comma delimited string.

DECLARE v_delimited_string_access_index INT;
DECLARE v_delimited_string_access_value VARCHAR(255);
DECLARE v_can_still_find_values_in_delimited_string BOOLEAN;

SET v_can_still_find_values_in_delimited_string = true;
SET v_delimited_string_access_index = 0;
WHILE (v_can_still_find_values_in_delimited_string) DO
  SET v_delimited_string_access_value = get_from_delimiter_split_string(in_array, ',', v_delimited_string_access_index); -- get value from string
  SET v_delimited_string_access_index = v_delimited_string_access_index + 1;
  IF (v_delimited_string_access_value = '') THEN
    SET v_can_still_find_values_in_delimited_string = false; -- no value at this index, stop looping
  ELSE
    -- DO WHAT YOU WANT WITH v_delimited_string_access_value HERE
  END IF;
END WHILE;

this uses the get_from_delimiter_split_string function defined here: https://stackoverflow.com/a/59666211/3068233

The programming language doesn't matter; measuring the runtime complexity of an algorithm works the same way regardless of the language. Analysis of Algorithms by Stanford on Google Code University is a very good resource for teaching yourself how to analyze the runtime complexity of algorithms and code.

If all you want to do is measure the elapsed time that a function or section of code took to run in Python, then you can use the timeit or time modules, depending on how long the code needs to run.

For Linux Users

Your app is not getting the path of android-sdk, so If you are using linux (ubuntu), than you need to add a file named "local.properties" and save it inside the android folder, which is created inside your app folder.

You need to add below line inside local.properties file, which is the path of your android-sdk lies inside your system inside system in order to run the app.

sdk.dir=/opt/android-sdk/

save and rerun the command react-native run-android

OR

you can open terminal, type

sudo nano ~/.bashrc

and paste the below path at the end of the file

export ANDROID_HOME="/opt/android-sdk/"

and restart your computer and run again react-native run-android after that.

Note:- If you put set path in .bashrc file, then you don't even need to create local.properties file.

While gcc 3.2.3 was more forgiving of the issue, gcc 4.1.2 is highlighting a potentially serious issue for the linking of your program later. Rather then trying to suppress the error you should make the forward declaration match the function declaration.

If you intended for the function to be globally available (as per the forward declaration) then don't subsequently declare it as static. Likewise if it's indented to be locally scoped then make the forward declaration static to match.

Hope my below code explains all. HTML:

(function($){_x000D_
_x000D_
     $("#btn_add").on("click",function(){_x000D_
       $("#btn_click").on("click",added_handler);_x000D_
       alert("Added new handler to button 1");_x000D_
     });_x000D_
_x000D_
  _x000D_
 _x000D_
     $("#btn_remove").on("click",function(){_x000D_
       $("#btn_click").off("click",added_handler);_x000D_
       alert("Removed new handler to button 1");_x000D_
     });_x000D_
_x000D_
  _x000D_
   function fixed_handler(){_x000D_
    alert("Fixed handler");_x000D_
  }_x000D_
  _x000D_
   function added_handler(){_x000D_
    alert("new handler");_x000D_
  }_x000D_
  _x000D_
  $("#btn_click").on("click",fixed_handler);_x000D_
  $("#btn_fixed").on("click",fixed_handler);_x000D_
  _x000D_
  _x000D_
})(jQuery);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button id="btn_click">Button 1</button>_x000D_
  <button id="btn_add">Add Handler</button>_x000D_
  <button id="btn_remove">Remove Handler</button>_x000D_
  <button id="btn_fixed">Fixed Handler</button>

First extract the string like this

var dateString = str.match(/^(\d{2})\/(\d{2})\/(\d{4})$/);

Then,

var d = new Date( dateString[3], dateString[2]-1, dateString[1] );

Instead of using recursion to deal with multi-dimensional arrays, which can be slow, you can do the following:

$res = json_decode(
    json_encode(
        iconv(
            mb_detect_encoding($res, mb_detect_order(), true),
            'UTF-8',
            $res
        )
    ),
    true
);

This will convert any character set to UTF8 and also preserve keys in your array. So instead of "lazy" converting each row using array_walk, you could do the whole result set in one go.

For me the following worked:

vagrant reload --provision

Even though you've accepted an answer, I want to post this method. I use jQuery to center it vertically instead of css (although both of these methods work). Here is a fiddle, and I'll post the code here anyways.

HTML:

<h1>Hello world!</h1>

Javascript (jQuery):

$(document).ready(function(){
  $('h1').css({ 'width':'100%', 'text-align':'center' });
  var h1 = $('h1').height();
  var h = h1/2;
  var w1 = $(window).height();
  var w = w1/2;
  var m = w - h
  $('h1').css("margin-top",m + "px")
});

This takes the height of the viewport, divides it by two, subtracts half the height of the h1, and sets that number to the margin-top of the h1. The beauty of this method is that it works on multiple-line h1s.

EDIT: I modified it so that it centered it every time the window is resized.

Only downside (it seems), is that the table cell widths are identical. Any way to get around this? – Josh Stodola Oct 12 at 15:53

Just define width of the table and width for each table cell

something like

table {border-collapse:collapse; table-layout:fixed; width:900px;}
th {background: yellow; }
td {overflow:hidden;white-space:nowrap; }
.cells1{width:300px;}
.cells2{width:500px;}
.cells3{width:200px;}

It works like a charm :o)

I'd consider the patterns you are using for your system, the naming conventions / cataloguing / grouping of classes of tends to be defined by the pattern used. Personally, I stick to these naming conventions as they are the most likely way for another person to be able to pick up my code and run with it.

For example UserRecordsClerk might be better explained as extending a generic RecordsClerk interface that both UserRecordsClerk and CompanyRecordsClerk implement and then specialise on, meaning one can look at the methods in the interface to see what the its subclasses do / are generally for.

See a book such as Design Patterns for info, it's an excellent book and might help you clear up where you're aiming to be with your code - if you aren't already using it! ;o)

I reckon so long as your pattern is well chosen and used as far as is appropriate, then pretty uninventive straightforward class names should suffice!

Use this css

.close-image {
    cursor: pointer;
    z-index: 3;
    right: 5px;
    top: 5px;
    position: absolute;
}

It is nor php nor html it sounds like specific xml tag.

Here is my take on this with jQuery. Solution isn't universal, meaning one would have to tweak some of the positions and stuff depending on the actual design.

Basically what I did is: on trigger clone/remove the whole background (what should be blurred) to a container with unblurred content (which, optionally, has hidden overflow if it is not full width) and position it correctly. Caveat is that on window resize blurred div will mismatch the original in terms of position, but this could be solved with some on window resize function (honestly I couldn't be bothered with that now).

I would really appreciate your opinion on this solution!

Thanks

You need the /g (global) option, like this:

var replaced = str.replace(/ /g, '+');

You can give it a try here. Unlike most other languages, JavaScript, by default, only replaces the first occurrence.

You could also disable all graphical menus by running this or placing it in your Rprofile

options(menu.graphics = FALSE)

function scrolltop() {

    var offset = 220;
    var duration = 500;

    jQuery(window).scroll(function() {
        if (jQuery(this).scrollTop() > offset) {
            jQuery('#back-to-top').fadeIn(duration);
        } else {
            jQuery('#back-to-top').fadeOut(duration);
        }
    });

    jQuery('#back-to-top').click(function(event) {
        event.preventDefault();
        jQuery('html, body').animate({scrollTop: 0}, duration);
        return false;
    });
}

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

The question is already answered, Updating answer to add the PyCharm bin directory to $PATH var, so that pycharm editor can be opened from anywhere(path) in terminal.

nano .bashrc

export PATH="<path-to-unpacked-pycharm-installation-directory>/bin:$PATH"

pycharm.sh

More simply you can utilize DropBox for this. The steps basically remain the same. You can do the following-:

1) upload your .ipa to dropBox, Share the link for this .ipa

2) Paste the shared link for .ipa in your manifest.plist file , Upload manifest file in DropBox again share the link for this .plist file

3)paste the link for this Plist in your index.html file with a suitable tag.

Share this index.html file with anybody who can tap on the URL and download. or you can directly hit the URL instead.

CMake 3.1 introduced the CMAKE_CXX_STANDARD variable that you can use. If you know that you will always have CMake 3.1 or later available, you can just write this in your top-level CMakeLists.txt file, or put it right before any new target is defined:

set (CMAKE_CXX_STANDARD 11)

If you need to support older versions of CMake, here is a macro I came up with that you can use:

macro(use_cxx11)
  if (CMAKE_VERSION VERSION_LESS "3.1")
    if (CMAKE_CXX_COMPILER_ID STREQUAL "GNU")
      set (CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
    endif ()
  else ()
    set (CMAKE_CXX_STANDARD 11)
  endif ()
endmacro(use_cxx11)

The macro only supports GCC right now, but it should be straight-forward to expand it to other compilers.

Then you could write use_cxx11() at the top of any CMakeLists.txt file that defines a target that uses C++11.

CMake issue #15943 for clang users targeting macOS

If you are using CMake and clang to target macOS there is a bug that can cause the CMAKE_CXX_STANDARD feature to simply not work (not add any compiler flags). Make sure that you do one of the following things:

• Use cmake_minimum_required to require CMake 3.0 or later, or

• Set policy CMP0025 to NEW with the following code at the top of your CMakeLists.txt file before the project command:

    # Fix behavior of CMAKE_CXX_STANDARD when targeting macOS.
    if (POLICY CMP0025)
      cmake_policy(SET CMP0025 NEW)
    endif ()
  

This behavior is explicitly documented in String.split(String regex) (emphasis mine):

This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

If you want those trailing empty strings included, you need to use String.split(String regex, int limit) with a negative value for the second parameter (limit):

String[] array = values.split("\\|", -1);

If child class has more members, than parent, it could be done not very clean, but short way:

@Data
@RequiredArgsConstructor
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
public class User extends BaseEntity {
    private @NonNull String fullName;
    private @NonNull String email;
    ... 

    public User(Integer id, String fullName, String email, ....) {
        this(fullName, email, ....);
        this.id = id;
    }
}

@Data
@AllArgsConstructor
abstract public class BaseEntity {
   protected Integer id;

   public boolean isNew() {
      return id == null;
   }
}

Try this in .htaccess:

IndexIgnore *.jpg

You might be able to use PDOStatement->debugDumpParams. See the PHP documentation .

I used this code to show the dialog at the bottom of the screen:

Dialog dlg = <code to create custom dialog>;

Window window = dlg.getWindow();
WindowManager.LayoutParams wlp = window.getAttributes();

wlp.gravity = Gravity.BOTTOM;
wlp.flags &= ~WindowManager.LayoutParams.FLAG_DIM_BEHIND;
window.setAttributes(wlp);

This code also prevents android from dimming the background of the dialog, if you need it. You should be able to change the gravity parameter to move the dialog about

private void showPictureialog() {
    final Dialog dialog = new Dialog(this,
            android.R.style.Theme_Translucent_NoTitleBar);

    // Setting dialogview
    Window window = dialog.getWindow();
    window.setGravity(Gravity.CENTER);

    window.setLayout(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    dialog.setTitle(null);
    dialog.setContentView(R.layout.selectpic_dialog);
    dialog.setCancelable(true);

    dialog.show();
}

you can customize you dialog based on gravity and layout parameters change gravity and layout parameter on the basis of your requirenment

I needed to snapshot a div on the page (for a webapp I wrote) that is protected by JWT's and makes very heavy use of Angular.

I had no luck with any of the above methods.

I ended up taking the outerHTML of the div I needed, cleaning it up a little (*) and then sending it to the server where I run wkhtmltopdf against it.

This is working very well for me.

(*) various input devices in my pages didn't render as checked or have their text values when viewed in the pdf... So I run a little bit of jQuery on the html before I send it up for rendering. ex: for text input items -- I copy their .val()'s into 'value' attributes, which then can be seen by wkhtmlpdf

In case you are here looking for a fast string concatenation method in Python, then you do not need a special StringBuilder class. Simple concatenation works just as well without the performance penalty seen in C#.

resultString = ""

resultString += "Append 1"
resultString += "Append 2"

See Antoine-tran's answer for performance results

I wasn't satisfied with the accepted answer so I created some scripts to do this for you available on Github. These should help anyone who wants to use git svn clone but doesn't want to clone the entire repository and doesn't want to hunt for a specific revision to clone from in the middle of the history (maybe you're cloning a bunch of repos). Here we can just clone the last N revisions:

Use git svn clone to clone the last 50 revisions

# -u    The SVN URL to clone
# -l    The limit of revisions
# -o    The output directory

./git-svn-cloneback.sh -u https://server/project/trunk -l 50 -o myproj --authors-file=svn-authors.txt

Find the previous N revision from an SVN repo

# -u    The SVN URL to clone
# -l    The limit of revisions

./svn-lookback.sh -u https://server/project/trunk -l 5     

This solution requires C++11 (or TR1).

#include <random>

int main()
{
   double lower_bound = 0;
   double upper_bound = 10000;
   std::uniform_real_distribution<double> unif(lower_bound,upper_bound);
   std::default_random_engine re;
   double a_random_double = unif(re);

   return 0;
}

For more details see John D. Cook's "Random number generation using C++ TR1".

See also Stroustrup's "Random number generation".

not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

The native lib is expected in one of the following locations

/usr/java/packages/lib/amd64
/usr/lib64
/lib64
/lib
/usr/lib

and not in

tomcat/lib

The files in tomcat/lib are all jar file and are added by tomcat to the classpath so that they are available to your application.

The native lib is needed by tomcat to perform better on the platform it is installed on and thus cannot be a jar, for linux it could be a .so file, for windows it could be a .dll file.

Just download the native library for your platform and place it in the one of the locations tomcat is expecting it to be.

Note that you are not required to have this lib for development/test purposes. Tomcat runs just fine without it.

org.apache.catalina.startup.Catalina start INFO: Server startup in 2882 ms

EDIT

The output you are getting is very normal, it's just some logging outputs from tomcat, the line right above indicates that the server correctly started and is ready for operating.

If you are troubling with running your servlet then after the run on sever command eclipse opens a browser window (embeded (default) or external, depends on your config). If nothing shows on the browser, then check the url bar of the browser to see whether your servlet was requested or not.

It should be something like that

http://localhost:8080/<your-context-name>/<your-servlet-name>

EDIT 2

Try to call your servlet using the following url

http://localhost:8080/com.filecounter/FileCounter

Also each web project has a web.xml, you can find it in your project under WebContent\WEB-INF.

It is better to configure your servlets there using servlet-name servlet-class and url-mapping. It could look like that:

  <servlet>
    <description></description>
    <display-name>File counter - My first servlet</display-name>
    <servlet-name>file_counter</servlet-name>
    <servlet-class>com.filecounter.FileCounter</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>file_counter</servlet-name>
    <url-pattern>/FileFounter</url-pattern>
  </servlet-mapping>

In eclipse dynamic web project the default context name is the same as your project name.

http://localhost:8080/<your-context-name>/FileCounter

will work too.

A lot of answers only explain how to do the search.

To view the results look for a search tab (normally docked at the bottom of the screen):

The problem with a LEFT JOIN is that if there are no appointments, it will still return one row with a null, which when aggregated by COUNT will become 1, and it will appear that the person has one appointment when actually they have none. I think this will give the correct results:

SELECT person.person_id,
(SELECT COUNT(*) FROM appointment WHERE person.person_id = appointment.person_id) AS 'Appointments'

You can get the favicon showing up in Django the same way you can do in any other framework: just use pure HTML.

Add the following code to the header of your HTML template.
Better, to your base HTML template if the favicon is the same across your application.

<link rel="shortcut icon" href="{% static 'favicon/favicon.png' %}"/>

The previous code assumes:

1. You have a folder named 'favicon' in your static folder
2. The favicon file has the name 'favicon.png'
3. You have properly set the setting variable STATIC_URL

You can find useful information about file format support and how to use favicons in this article of Wikipedia https://en.wikipedia.org/wiki/Favicon.
I can recommend use .png for universal browser compatibility.

EDIT:
As posted in one comment,
"Don't forget to add {% load staticfiles %} in top of your template file!"

If you are not using SSMS then here is the syntax:

ALTER TABLE <table_name>
ADD <constraint_name> FOREIGN KEY 
(<column_name1> ,
<column_name2> )
REFERENCES <table_name>
(<column_name1> ,
<column_name2>)

Rendering react as pdf is generally a pain, but there is a way around it using canvas.

The idea is to convert : HTML -> Canvas -> PNG (or JPEG) -> PDF

To achieve the above, you'll need :

1. html2canvas &
2. jsPDF

import React, {Component, PropTypes} from 'react';_x000D_
_x000D_
// download html2canvas and jsPDF and save the files in app/ext, or somewhere else_x000D_
// the built versions are directly consumable_x000D_
// import {html2canvas, jsPDF} from 'app/ext';_x000D_
_x000D_
_x000D_
export default class Export extends Component {_x000D_
  constructor(props) {_x000D_
    super(props);_x000D_
  }_x000D_
_x000D_
  printDocument() {_x000D_
    const input = document.getElementById('divToPrint');_x000D_
    html2canvas(input)_x000D_
      .then((canvas) => {_x000D_
        const imgData = canvas.toDataURL('image/png');_x000D_
        const pdf = new jsPDF();_x000D_
        pdf.addImage(imgData, 'JPEG', 0, 0);_x000D_
        // pdf.output('dataurlnewwindow');_x000D_
        pdf.save("download.pdf");_x000D_
      })_x000D_
    ;_x000D_
  }_x000D_
_x000D_
  render() {_x000D_
    return (<div>_x000D_
      <div className="mb5">_x000D_
        <button onClick={this.printDocument}>Print</button>_x000D_
      </div>_x000D_
      <div id="divToPrint" className="mt4" {...css({_x000D_
        backgroundColor: '#f5f5f5',_x000D_
        width: '210mm',_x000D_
        minHeight: '297mm',_x000D_
        marginLeft: 'auto',_x000D_
        marginRight: 'auto'_x000D_
      })}>_x000D_
        <div>Note: Here the dimensions of div are same as A4</div> _x000D_
        <div>You Can add any component here</div>_x000D_
      </div>_x000D_
    </div>);_x000D_
  }_x000D_
}

The snippet will not work here because the required files are not imported.

An alternate approach is being used in this answer, where the middle steps are dropped and you can simply convert from HTML to PDF. There is an option to do this in the jsPDF documentation as well, but from personal observation, I feel that better accuracy is achieved when dom is converted into png first.

Update 0: September 14, 2018

The text on the pdfs created by this approach will not be selectable. If that's a requirement, you might find this article helpful.

I found very good link for JSON: http://code.google.com/p/json-simple/wiki/EncodingExamples#Example_1-1_-_Encode_a_JSON_object

Here's code to add multiple JSONObjects to JSONArray.

JSONArray Obj = new JSONArray();
try {
    for(int i = 0; i < 3; i++) {
        // 1st object
        JSONObject list1 = new JSONObject();
        list1.put("val1",i+1);
        list1.put("val2",i+2);
        list1.put("val3",i+3);
        obj.put(list1);
    }

} catch (JSONException e1) {
    // TODO Auto-generated catch block
    e1.printStackTrace();
}             
Toast.makeText(MainActivity.this, ""+obj, Toast.LENGTH_LONG).show();

Following the instructions from this page,

1. Open the XAMPP control panel (cmd-space, then enter manager-osx.app).
2. Select Manage Servers tab -> select Apache Web Server -> click Configure.
3. Click Open Conf File. Provide credentials if asked.

4. Change

   <IfModule unixd_module>
   #
   # If you wish httpd to run as a different user or group, you must run
   # httpd as root initially and it will switch.  
   #
   # User/Group: The name (or #number) of the user/group to run httpd as.
   # It is usually good practice to create a dedicated user and group for
   # running httpd, as with most system services.
   #
   User daemon
   Group daemon
   </IfModule>
   

   to

   <IfModule unixd_module>
   #
   # If you wish httpd to run as a different user or group, you must run
   # httpd as root initially and it will switch.  
   #
   # User/Group: The name (or #number) of the user/group to run httpd as.
   # It is usually good practice to create a dedicated user and group for
   # running httpd, as with most system services.
   #
   User your_username
   Group staff
   </IfModule>
   

5. Save and close.

6. Using the XAMPP control panel, restart Apache.

7. Navigate to the document root of your server and make yourself the owner. The default is /Applications/XAMPP/xamppfiles/htdocs.

   $ cd your_document_root
   $ sudo chown -R your_username:staff .
   

8. Navigate to the xamppfiles directory and change the permission for logs and temp directory.

   $ cd /Applications/XAMPP/xamppfiles
   $ sudo chown -R your_username:staff logs
   $ sudo chown -R your_username:staff temp
   

9. To be able to use phpmyadmin you have to change the permissions for config.inc.php.

   $ cd /Applications/XAMPP/xamppfiles/phpmyadmin
   $ sudo chown your_username:staff config.inc.php
   

One more cause for this:

If the routes are overridden with the same URI (Unknowingly), it causes this error:

Eg:

Route::get('dashboard', ['uses' => 'SomeController@index', 'as' => 'my.dashboard']);
Route::get('dashboard/', ['uses' => 'SomeController@dashboard', 'as' => 'my.home_dashboard']);

In this case route 'my.dashboard' is invalidate as the both routes has same URI ('dashboard', 'dashboard/')

Solution: You should change the URI for either one

Eg:

Route::get('dashboard', ['uses' => 'SomeController@index', 'as' => 'my.dashboard']);
Route::get('home-dashboard', ['uses' => 'SomeController@dashboard', 'as' => 'my.home_dashboard']); 

// See the URI changed for this 'home-dashboard'

Hope it helps some once.

You can use the description method inherited by NSDictionary from NSObject, or write a custom method that formats NSDictionary to your liking.

"Pause" and "resume" don't really make much sense in the context of setTimeout, which is a one-off thing. Do you mean setInterval? If so, no, you can't pause it, you can only cancel it (clearInterval) and then re-schedule it again. Details of all of these in the Timers section of the spec.

// Setting
var t = setInterval(doSomething, 1000);

// Pausing (which is really stopping)
clearInterval(t);
t = 0;

// Resuming (which is really just setting again)
t = setInterval(doSomething, 1000);

Globals in Python are global to a module, not across all modules. (Many people are confused by this, because in, say, C, a global is the same across all implementation files unless you explicitly make it static.)

There are different ways to solve this, depending on your actual use case.

Before even going down this path, ask yourself whether this really needs to be global. Maybe you really want a class, with f as an instance method, rather than just a free function? Then you could do something like this:

import module1
thingy1 = module1.Thingy(a=3)
thingy1.f()

If you really do want a global, but it's just there to be used by module1, set it in that module.

import module1
module1.a=3
module1.f()

On the other hand, if a is shared by a whole lot of modules, put it somewhere else, and have everyone import it:

import shared_stuff
import module1
shared_stuff.a = 3
module1.f()

… and, in module1.py:

import shared_stuff
def f():
    print shared_stuff.a

Don't use a from import unless the variable is intended to be a constant. from shared_stuff import a would create a new a variable initialized to whatever shared_stuff.a referred to at the time of the import, and this new a variable would not be affected by assignments to shared_stuff.a.

Or, in the rare case that you really do need it to be truly global everywhere, like a builtin, add it to the builtin module. The exact details differ between Python 2.x and 3.x. In 3.x, it works like this:

import builtins
import module1
builtins.a = 3
module1.f()

I've seen GCC turn the conditional operator into cmov (conditional move) instructions, while turning if statements into branches, which meant in our case, the code was faster when using the conditional operator. But that was a couple of years ago, and most likely today, both would compile to the same code.

There's no guarantee that they'll compile to the same code. If you need the performance then, as always, measure. And when you've measured and found out that 1. your code is too slow, and 2. it is this particular chunk of code that is the culprit, then study the assembly code generated by the compiler and check for yourself what is happening.

Don't trust golden rules like "the compiler will always generate more efficient code if I use the conditional operator".

Hi I got the solution by using this :

You have to execute this command from terminal. I got the result,

adb logcat | grep `adb shell ps | grep com.package | cut -c10-15`

just simply use as below and it will word wrap any long text within a table . No need to anything else

<td style="word-wrap: break-word;min-width: 160px;max-width: 160px;">long long comments</td>

the simpler, the better.

index.php

<? 
if (empty($_SERVER['QUERY_STRING'])) { 
  $name="index"; 
} else { 
  $name=basename($_SERVER['QUERY_STRING']); 
} 
$file="txt/".$name.".htm"; 
if (is_readable($file)) { 
  include 'header.php';
  readfile($file);
} else { 
  header("HTTP/1.0 404 Not Found");
  exit;
} 
?>

header.php

<a href="index.php">Main page</a><br>
<a href=?about>About</a><br>
<a href=?links>Links</a><br>
<br><br> 

the actual static html pages stored in the txt folder in the page.htm format

Try with below code sample.it is working for me

var date_input_field = $('input[name="date"]');
    date_input_field .datepicker({
        dateFormat: '/dd/mm/yyyy',
        container: container,
        todayHighlight: true,
        autoclose: true,
    }).on('change', function(selected){
        alert("startDate..."+selected.timeStamp);
    });

It is likely that you are running the python executable from /usr/bin (Apple version) instead of /usr/loca/bin (Brew version)

You can either

a) check your PATH variable

or

b) run brew doctor

or

c) run which python

to check if it is the case.

Edit: typeahead is no longer bundled in Bootstrap 3. Check out:

• Where is the typeahead JavaScript module in Bootstrap 3 RC 1?
• typeahead.js

As of Bootstrap 2.1.0 up to 2.3.2, you can do this:

$('.typeahead').typeahead({
    source: function (query, process) {
        return $.get('/typeahead', { query: query }, function (data) {
            return process(data.options);
        });
    }
});

To consume JSON data like this:

{
    "options": [
        "Option 1",
        "Option 2",
        "Option 3",
        "Option 4",
        "Option 5"
    ]
}

Note that the JSON data must be of the right mime type (application/json) so jQuery recognizes it as JSON.

The __del__ method (note spelling!) is called when your object is finally destroyed. Technically speaking (in cPython) that is when there are no more references to your object, ie when it goes out of scope.

If you want to delete your object and thus call the __del__ method use

del obj1

which will delete the object (provided there weren't any other references to it).

I suggest you write a small class like this

class T:
    def __del__(self):
        print "deleted"

And investigate in the python interpreter, eg

>>> a = T()
>>> del a
deleted
>>> a = T()
>>> b = a
>>> del b
>>> del a
deleted
>>> def fn():
...     a = T()
...     print "exiting fn"
...
>>> fn()
exiting fn
deleted
>>>   

Note that jython and ironpython have different rules as to exactly when the object is deleted and __del__ is called. It isn't considered good practice to use __del__ though because of this and the fact that the object and its environment may be in an unknown state when it is called. It isn't absolutely guaranteed __del__ will be called either - the interpreter can exit in various ways without deleteting all objects.

Removing floats, and using inline-block may fix your problems:

 .pagination a {
-    display: block;
+    display: inline-block;
     width: 30px;
     height: 30px;
-    float: left;
     margin-left: 3px;
     background: url(/images/structure/pagination-button.png);
 }

(remove the lines starting with - and add the lines starting with +.)

.pagination {_x000D_
  text-align: center;_x000D_
}_x000D_
.pagination a {_x000D_
  + display: inline-block;_x000D_
  width: 30px;_x000D_
  height: 30px;_x000D_
  margin-left: 3px;_x000D_
  background: url(/images/structure/pagination-button.png);_x000D_
}_x000D_
.pagination a.last {_x000D_
  width: 90px;_x000D_
  background: url(/images/structure/pagination-button-last.png);_x000D_
}_x000D_
.pagination a.first {_x000D_
  width: 60px;_x000D_
  background: url(/images/structure/pagination-button-first.png);_x000D_
}

<div class='pagination'>_x000D_
  <a class='first' href='#'>First</a>_x000D_
  <a href='#'>1</a>_x000D_
  <a href='#'>2</a>_x000D_
  <a href='#'>3</a>_x000D_
  <a class='last' href='#'>Last</a>_x000D_
</div>_x000D_
<!-- end: .pagination -->

inline-block works cross-browser, even on IE6 as long as the element is originally an inline element.

Quote from quirksmode:

An inline block is placed inline (ie. on the same line as adjacent content), but it behaves as a block.

this often can effectively replace floats:

The real use of this value is when you want to give an inline element a width. In some circumstances some browsers don't allow a width on a real inline element, but if you switch to display: inline-block you are allowed to set a width.” ( http://www.quirksmode.org/css/display.html#inlineblock ).

From the W3C spec:

[inline-block] causes an element to generate an inline-level block container. The inside of an inline-block is formatted as a block box, and the element itself is formatted as an atomic inline-level box.

At least in Postgres you can use the following statement:

SELECT EntityID, EntityName, EntityProfile IS NOT NULL AS HasProfile FROM Entity

i had a similar issue using enum with switch cases later i resolved it on my own....below is the corrected code, perhaps this might help.

     //Menu Chooser Programe using enum
     #include<iostream>
     using namespace std;
     int main()
     {
        enum level{Novice=1, Easy, Medium, Hard};
        level diffLevel=Novice;
        int i;
        cout<<"\nenter a level: ";
        cin>>i;
        switch(i)
        {
        case Novice: cout<<"\nyou picked Novice\n"; break;
        case Easy: cout<<"\nyou picked Easy\n"; break;
        case Medium: cout<<"\nyou picked Medium\n"; break;
        case Hard: cout<<"\nyou picked Hard\n"; break;
        default: cout<<"\nwrong input!!!\n"; break;
        }
        return 0;
     }

While existing answers definitely solve the purpose, if your'e looking to replicate nested directory structure under two different subdirectories, then you can do this

mkdir -p {main,test}/{resources,scala/com/company}

It will create following directory structure under the directory from where it is invoked

+-- main
¦   +-- resources
¦   +-- scala
¦       +-- com
¦           +-- company
+-- test
    +-- resources
    +-- scala
        +-- com
            +-- company

The example was taken from this link for creating SBT directory structure

just add onclick handler for anchor tag

onclick="this.parentNode.style.display = 'none'"

or change onclick handler for img tag

onclick="this.parentNode.parentNode.style.display = 'none'"

you can consider something like that:

1. define a style for textblock, or any other control you want to use to display your enum:

   <Style x:Key="enumStyle" TargetType="{x:Type TextBlock}">
       <Setter Property="Text" Value="&lt;NULL&gt;"/>
       <Style.Triggers>
           <Trigger Property="Tag">
               <Trigger.Value>
                   <proj:YourEnum>Value1<proj:YourEnum>
               </Trigger.Value>
               <Setter Property="Text" Value="{DynamicResource yourFriendlyValue1}"/>
           </Trigger>
           <!-- add more triggers here to reflect your enum -->
       </Style.Triggers>
   </Style>
   

2. define your style for ComboBoxItem

   <Style TargetType="{x:Type ComboBoxItem}">
       <Setter Property="ContentTemplate">
           <Setter.Value>
               <DataTemplate>
                   <TextBlock Tag="{Binding}" Style="{StaticResource enumStyle}"/>
               </DataTemplate>
           </Setter.Value>
       </Setter>
   </Style>
   

3. add a combobox and load it with your enum values:

   <ComboBox SelectedValue="{Binding Path=your property goes here}" SelectedValuePath="Content">
       <ComboBox.Items>
           <ComboBoxItem>
               <proj:YourEnum>Value1</proj:YourEnum>
           </ComboBoxItem>
       </ComboBox.Items>
   </ComboBox>
   

if your enum is large, you can of course do the same in code, sparing a lot of typing. i like that approach, since it makes localization easy - you define all the templates once, and then, you only update your string resource files.

Try =Year(Now()) and format the cell as General.

In short you have to do like this

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "https://maven.fabric.io/public" }
}

Detail:

You need to specify each maven URL in its own curly braces. Here is what I got working with skeleton dependencies for the web services project I’m going to build up:

apply plugin: 'java'

sourceCompatibility = 1.7
version = '1.0'

repositories {
  maven { url "http://maven.springframework.org/release" }
  maven { url "http://maven.restlet.org" }
  mavenCentral()
}

dependencies {
  compile group:'org.restlet.jee', name:'org.restlet', version:'2.1.1'
  compile group:'org.restlet.jee', name:'org.restlet.ext.servlet',version.1.1'
  compile group:'org.springframework', name:'spring-web', version:'3.2.1.RELEASE'
  compile group:'org.slf4j', name:'slf4j-api', version:'1.7.2'
  compile group:'ch.qos.logback', name:'logback-core', version:'1.0.9'
  testCompile group:'junit', name:'junit', version:'4.11'
}

You need to have a byte[] in your DB.

My byte[] is in my Person object:

public class Person
{
    public byte[] Image { get; set; }
}

You need to convert your byte[] in a String. So, I have in my controller :

String img = Convert.ToBase64String(person.Image);

Next, in my .cshtml file, my Model is a ViewModel. This is what I have in :

 public String Image { get; set; }

I use it like this in my .cshtml file:

<img src="@String.Format("data:image/jpg;base64,{0}", Model.Image)" />

"data:image/image file extension;base64,{0}, your image String"

I wish it will help someone !

You want to use regex lookahead and lookbehind. This will give you only what is inside the curly braces:

(?<=\{)(.*?)(?=\})

You should set both your table encoding and connection encoding to UTF-8:

ALTER TABLE keywords CHARACTER SET UTF8; -- run once

and

SET NAMES 'UTF8';
SET CHARACTER SET 'UTF8';

The original syntax will work with BASH but not with DASH. On debian systems you might think you are using bash, but maybe dash instead. If /bin/dash/exist then try temporarily renaming dash to something like no.dash, and then create soft a link, aka ln -s /bin/bash /bin/dash and see if that fixes the problem.

• The answer is Yes if the query is run multiple times at once, because each transaction won't need to wait for the others to complete. However, If the query is run once on its own then the answer is No.

• Yes. There's a significant probability that careful use of WITH(NOLOCK) will speed up your database overall. It means that other transactions won't have to wait for this SELECT statement to finish, but on the other hand, other transactions will slow down as they're now sharing their processing time with a new transaction.

Be careful to only use WITH (NOLOCK) in SELECT statements on tables that have a clustered index.

WITH(NOLOCK) is often exploited as a magic way to speed up database read transactions.

The result set can contain rows that have not yet been committed, that are often later rolled back.

If WITH(NOLOCK) is applied to a table that has a non-clustered index then row-indexes can be changed by other transactions as the row data is being streamed into the result-table. This means that the result-set can be missing rows or display the same row multiple times.

READ COMMITTED adds an additional issue where data is corrupted within a single column where multiple users change the same cell simultaneously.

As Ajay beniwal mentioned above you need to use Apply to start digestion.

var app = angular.module('test', []);

app.controller('TestCtrl', function ($scope) {
   $scope.testValue = 0;

    setInterval(function() {
        console.log($scope.testValue++);
        $scope.$apply() 
    }, 500);
});

There are quite a few options that can be used: (both tested).

Here are two ways.

header("Content-type: application/pdf");
header("Content-Disposition: inline; filename=filename.pdf");
@readfile('path\to\filename.pdf');

or: (note the escaped double-quotes). The same need to be use when assigning a name to it.

<?php

echo "<iframe src=\"file.pdf\" width=\"100%\" style=\"height:100%\"></iframe>";

?>

I.e.: name="myiframe" id="myiframe"

would need to be changed to:

name=\"myiframe\" id=\"myiframe\" inside PHP.

Be sure to have a look at: this answer on SO for more options on the subject.

The default port 1433 is used when there is only one SQL Server named instance running on the computer.

When multiple SQL Server named instances are running, they run by default under a dynamic port (49152–65535). In this scenario, an application will connect to the SQL Server Browser service port (UDP 1434) to get the dynamic port and then connect to the dynamic port directly.

Suppose you have a big project written in c++ which has a thousand of .cpp files and a thousand of .h files.And let's says the project also depends on ten static libraries. Let's says we are on Windows and we build our project in Visual Studio 20xx. When you press Ctrl + F7 Visual Studio to start compiling the whole solution ( suppose we have just one project in the solution )

What's the meaning of compilation ?

• Visual Studio search into file .vcxproj and start compiling each file which has the extension .cpp. Order of compilation is undefined.So you must not assume that the file main.cpp is compiled first
• If .cpp files depends on additional .h files in order to find symbols that may or may not be defined in the file .cpp
• If exists one .cpp file in which the compiler could not find one symbol, a compiler time error raises the message Symbol x could not be found
• For each file with extension .cpp is generated an object file .o and also Visual Studio writes the output in a file named ProjectName.Cpp.Clean.txt which contains all object files that must be processed by the linker.

The Second step of compilation is done by Linker.Linker should merge all the object file and build finally the output ( which may be an executable or a library)

Steps In Linking a project

• Parse all the object files and find the definition which was only declared in headers ( eg: The code of one method of a class as is mentioned in previous answers, or event the initialization of a static variable which is member inside a class)
• If one symbol could not be found in object files he also is searched in Additional Libraries.For adding a new library to a project Configuration properties -> VC++ Directories -> Library Directories and here you specified additional folder for searching libraries and Configuration properties -> Linker -> Input for specifying the name of the library. -If the Linker could not find the symbol which you write in one .cpp he raises a linker time error which may sound like error LNK2001: unresolved external symbol "void __cdecl foo(void)" (?foo@@YAXXZ)

Observation

1. Once the Linker find one symbol he doesn't search in other libraries for it
2. The order of linking libraries does matter.
3. If Linker finds an external symbol in one static library he includes the symbol in the output of the project.However, if the library is shared( dynamic ) he doesn't include the code ( symbols ) in output, but Run-Time crashes may occur

How To Solve this kind of error

Compiler Time Error :

• Make sure you write your c++ project syntactical correct.

Linker Time Error

• Define all your symbol which you declare in your header files
• Use #pragma once for allowing compiler not to include one header if it was already included in the current .cpp which are compiled
• Make sure that your external library doesn't contain symbols that may enter into conflict with other symbols you defined in your header files
• When you use the template to make sure you include the definition of each template function in the header file for allowing the compiler to generate appropriate code for any instantiations.

the other way to exchange data from php to javascript or vice versa is by using cookies, you can save cookies in php and read by your javascript, for this you don't have to use forms or ajax

If it's a deeper key/value you're after and you're not dealing with arrays of keys/values at each level, you could recursively search the tree:

public static String recurseKeys(JSONObject jObj, String findKey) throws JSONException {
    String finalValue = "";
    if (jObj == null) {
        return "";
    }

    Iterator<String> keyItr = jObj.keys();
    Map<String, String> map = new HashMap<>();

    while(keyItr.hasNext()) {
        String key = keyItr.next();
        map.put(key, jObj.getString(key));
    }

    for (Map.Entry<String, String> e : (map).entrySet()) {
        String key = e.getKey();
        if (key.equalsIgnoreCase(findKey)) {
            return jObj.getString(key);
        }

        // read value
        Object value = jObj.get(key);

        if (value instanceof JSONObject) {
            finalValue = recurseKeys((JSONObject)value, findKey);
        }
    }

    // key is not found
    return finalValue;
}

Usage:

JSONObject jObj = new JSONObject(jsonString);
String extract = recurseKeys(jObj, "extract");

Using Map code from https://stackoverflow.com/a/4149555/2301224

Note: z-index only works on positioned elements (position:absolute, position:relative, or position:fixed). Use one of those.

First of all, in your device go to Dev. Option -> ADB over Network after do it:

$ adb connect <your device adb network>
$ react-native run-android 

(or run-ios, by the way)

if this has successfully your device has installed app-debug.apk, open app-debug and go to Dev. Settings -> Debug server host & port for device, type in your machine's IP address (generally, System preference -> Network), as in the example below < your machine's IP address >:8081 (whihout inequality)

finally, execute the command below

$ react-native start --port=8081

try another ports, and verify that you machine and your device are same network.

There is another cause for this type of problem what I would like to share, because I struggle in this problem for some time and I could't find any answer on SO.

In a repository like:

@Repository
public interface UserEntityDao extends CrudRepository<UserEntity, Long>{

}

If your entity UserEntity does not have the @Entity annotation on the class, you will have the same error.

This error is confusing for this case, because you focus on trying to resolve the problem about Spring not found the Repository but the problem is the entity. And if you came to this answer trying to test your Repository, this answer may help you.

on tables with many rows are two queries probably faster...

SELECT @last_id := MAX(id) FROM table;

SELECT * FROM table WHERE id = @last_id;

In VB.net use for the Sub:

    Private Sub dgv_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles dgv.MouseUp
    ' deselezionare se click su vuoto
    If e.Button = MouseButtons.Left Then
        ' Check the HitTest information for this click location
        If Equals(dgv.HitTest(e.X, e.Y), DataGridView.HitTestInfo.Nowhere) Then
            dgv.ClearSelection()
            dgv.CurrentCell = Nothing
        End If
    End If
End Sub

Use of whitespace in RE is a pain, but I believe they work. The OP's problem can also be solved using StringTokenizer or the split() method. However, to use RE (uncomment the println() to view how the matcher is breaking up the String), here is a sample code:

import java.util.regex.*;

public class Two21WS {
    private String  str = "";
    private Pattern pattern = Pattern.compile ("\\s{2,}");  // multiple spaces

    public Two21WS (String s) {
            StringBuffer sb = new StringBuffer();
            Matcher matcher = pattern.matcher (s);
            int startNext = 0;
            while (matcher.find (startNext)) {
                    if (startNext == 0)
                            sb.append (s.substring (0, matcher.start()));
                    else
                            sb.append (s.substring (startNext, matcher.start()));
                    sb.append (" ");
                    startNext = matcher.end();
                    //System.out.println ("Start, end = " + matcher.start()+", "+matcher.end() +
                    //                      ", sb: \"" + sb.toString() + "\"");
            }
            sb.append (s.substring (startNext));
            str = sb.toString();
    }

    public String toString () {
            return str;
    }

    public static void main (String[] args) {
            String tester = " a    b      cdef     gh  ij   kl";
            System.out.println ("Initial: \"" + tester + "\"");
            System.out.println ("Two21WS: \"" + new Two21WS(tester) + "\"");
}}

It produces the following (compile with javac and run at the command prompt):

% java Two21WS Initial: " a b cdef gh ij kl" Two21WS: " a b cdef gh ij kl"

I have run into this problem multiple times when the JSON has been edited by hand. If someone was to delete something from the file without noticing it can throw the same error.

For instance, If your JSON last "}" is missing it will throw the same error.

So If you edit you file by hand make sure you format it like it is expected by the JSON decoder, otherwise you will run into the same problem.

Hope this helps!

charAt gets a character from a string, and you can switch on them since char is an integer type.

So to switch on the first char in the String hello,

switch (hello.charAt(0)) {
  case 'a': ... break;
}

You should be aware though that Java chars do not correspond one-to-one with code-points. See codePointAt for a way to reliably get a single Unicode codepoints.

Another option would be to just use the excellent corrr package https://github.com/drsimonj/corrr and do

require(corrr)
require(dplyr)

myData %>% 
   select(x,y,z) %>%  # or do negative or range selections here
   correlate() %>%
   rearrange() %>%  # rearrange by correlations
   shave() # Shave off the upper triangle for a cleaner result

Steps 3 and 4 are entirely optional and are just included to demonstrate the usefulness of the package.

Your only option is to somehow clone the object.

See this stackoverflow question on how you can achieve this.

For simple JSON objects, the simplest way would be:

var newObject = JSON.parse(JSON.stringify(oldObject));

if you use jQuery, you can use:

// Shallow copy
var newObject = jQuery.extend({}, oldObject);

// Deep copy
var newObject = jQuery.extend(true, {}, oldObject);

UPDATE 2017: I should mention, since this is a popular answer, that there are now better ways to achieve this using newer versions of javascript:

In ES6 or TypeScript (2.1+):

var shallowCopy = { ...oldObject };

var shallowCopyWithExtraProp = { ...oldObject, extraProp: "abc" };

Note that if extraProp is also a property on oldObject, its value will not be used because the extraProp : "abc" is specified later in the expression, which essentially overrides it. Of course, oldObject will not be modified.

Tony is a pure genius. However to achieve even better auto-completion try setting the triggers to this:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz =.(!+-*/~,[{@#$%^&

(specifically aranged in order of usage for faster performance :)

This is the easiest way to do this...

sql = "select username from usermst where userid=2"
object getusername = command.ExecuteScalar();
if (getusername!=null)
{
    //do whatever with the value here
    //use getusername.toString() to get the value from the query
}

var array = string.split(',')

and good morning, too, since I have to type 30 chars ...

i improved the solutions of RHTs/Brad Ms and of Lestos answer.

i extended both solutions in leaving the state there, where it was found. So i save the current ResultSet position and restore it after i created the maps.

The rs is the ResultSet, its a field variable and so in my solutions-snippets not visible.

I replaced the specific Map in Brad Ms solution to the gerneric Map.

    public List<Map<String, Object>> resultAsListMap() throws SQLException
    {
        var md = rs.getMetaData();
        var columns = md.getColumnCount();
        var list = new ArrayList<Map<String, Object>>();

        var currRowIndex = rs.getRow();
        rs.beforeFirst();

        while (rs.next())
        {
            HashMap<String, Object> row = new HashMap<String, Object>(columns);
            for (int i = 1; i <= columns; ++i)
            {
                row.put(md.getColumnName(i), rs.getObject(i));
            }

            list.add(row);
        }

        rs.absolute(currRowIndex);

        return list;
    }

In Lestos solution, i optimized the code. In his code he have to lookup the Maps each iteration of that for-loop. I reduced that to only one array-acces each for-loop iteration. So the program must not seach each iteration step for that string-key.

    public Map<String, List<Object>> resultAsMapList() throws SQLException
    {
        var md = rs.getMetaData();
        var columns = md.getColumnCount();
        var tmp = new ArrayList[columns];
        var map = new HashMap<String, List<Object>>(columns);

        var currRowIndex = rs.getRow();
        rs.beforeFirst();

        for (int i = 1; i <= columns; ++i)
        {
            tmp[i - 1] = new ArrayList<>();
            map.put(md.getColumnName(i), tmp[i - 1]);
        }

        while (rs.next())
        {
            for (int i = 1; i <= columns; ++i)
            {
                tmp[i - 1].add(rs.getObject(i));
            }
        }

        rs.absolute(currRowIndex);

        return map;
    }

Assuming that you only have one pair of parenthesis.

string s = "User name (sales)";
int start = s.IndexOf("(") + 1;
int end = s.IndexOf(")", start);
string result = s.Substring(start, end - start);

As of : moment.js version 2.24.0

let's say you have a local date input, this is the proper way to convert your dateTime or Time input to UTC :

var utcStart = new moment("09:00", "HH:mm").utc();

or in case you specify a date

var utcStart = new moment("2019-06-24T09:00", "YYYY-MM-DDTHH:mm").utc();

As you can see the result output will be returned in UTC :

//You can call the format() that will return your UTC date in a string 
 utcStart.format(); 
//Result : 2019-06-24T13:00:00 

But if you do this as below, it will not convert to UTC :

var myTime = new moment.utc("09:00", "HH:mm"); 

You're only setting your input to utc time, it's as if your mentioning that myTime is in UTC, ....the output will be 9:00

You can try using a regex like this:

$s = preg_replace('|/.*$|', '', $s);

sometimes, regex are slower though, so if performance is an issue, make sure to benchmark this properly and use an other alternative with substrings if it's more suitable for you.

The only reason I can think of is you are adding it as string 'now()', not function call now().
Or whatever else typo.

SELECT NOW();

to see if it returns correct value?

I would do it this way. Assuming I have a JSON of movies ...

movies.forEach((obj) => {
  Object.entries(obj).forEach(([key, value]) => {
    console.log(`${key} ${value}`);
  });
});

Sushant Gupta's answers are a tad bit outdated and don't work anymore.

The following snippet should be like this now :

collection.find({}, {"sort" : ['datefield', 'asc']} ).toArray(function(err,docs) {});

And in case you come here, like I did, looking to do the same thing for plots in a Julia notebook in Jupyter, using Plots, you can use:

    IJulia.clear_output(true)

so for a kind of animated plot of multiple runs

    if nrun==1  
      display(plot(x,y))         # first plot
    else 
      IJulia.clear_output(true)  # clear the window (as above)
      display(plot!(x,y))        # plot! overlays the plot
    end

Without the clear_output call, all plots appear separately.

You can write your select query as,

select * from table_name where to_char(date_time_column, 'YYYY-MM')  = '2011-03';

Just to add to Benjamin's answer — class variables are possible, but you wouldn't use prototype to set them.

For a true class variable you'd want to do something like the following:

class MyClass {}
MyClass.foo = 'bar';

From within a class method that variable can be accessed as this.constructor.foo (or MyClass.foo).

These class properties would not usually be accessible from to the class instance. i.e. MyClass.foo gives 'bar' but new MyClass().foo is undefined

If you want to also have access to your class variable from an instance, you'll have to additionally define a getter:

class MyClass {
    get foo() {
        return this.constructor.foo;
    }
}

MyClass.foo = 'bar';

I've only tested this with Traceur, but I believe it will work the same in a standard implementation.

JavaScript doesn't really have classes. Even with ES6 we're looking at an object- or prototype-based language rather than a class-based language. In any function X () {}, X.prototype.constructor points back to X. When the new operator is used on X, a new object is created inheriting X.prototype. Any undefined properties in that new object (including constructor) are looked up from there. We can think of this as generating object and class properties.

Just for fun:

var mystring = "this,is,a,test"  
var newchar = '|'
mystring = mystring.split(',').join(newchar);

Add the following command to your .vimrc to turn of the end-of-line option:

autocmd FileType php setlocal noeol binary fileformat=dos

However, PHP itself will ignore that last end-of-line - it shouldn't be an issue. I am almost certain that in your case there is something else which is adding the last newline character, or possibly there is a mixup with windows/unix line ending types (\n or \r\n, etc).

Update:

An alternative solution might be to just add this line to your .vimrc:

set fileformats+=dos

                        sBuilder.Append(data[i].ToString("x2"));
                    }

                    // Return the hexadecimal string.
                    return sBuilder.ToString();
                }
            }

            // Verify a hash against a string.
            static bool VerifyMd5Hash(string input, string hash)
            {
                // Hash the input.
                string hashOfInput = GetMd5Hash(input);

                // Create a StringComparer an compare the hashes.
                StringComparer comparer = StringComparer.OrdinalIgnoreCase;

                return 0 == comparer.Compare(hashOfInput, hash);

            }

Add an = at the beginning. That makes it a function rather than an entry.

I second Jon Skeet's answer and want to add the following links for everyone who want to know more about "volatile" and Interlocked:

Atomicity, volatility and immutability are different, part one - (Eric Lippert's Fabulous Adventures In Coding)

Atomicity, volatility and immutability are different, part two

Atomicity, volatility and immutability are different, part three

Unfortunately there's no min (or max)-background-size in CSS you can only use background-size. However if you are seeking a responsive background image you can use Vmin and Vmaxunits for the background-size property to achieve something similar.

example:

#one {
    background:url('../img/blahblah.jpg') no-repeat;
    background-size:10vmin 100%;
}

that will set the height to 10% of the whichever smaller viewport you have whether vertical or horizontal, and will set the width to 100%.

Read more about css units here: https://www.w3schools.com/cssref/css_units.asp

This will definitely work for you.

android:windowSoftInputMode="adjustPan"

According to w3c, the default value for the MAXLENGTH attribute is an unlimited number. So if you don't specify the max a user could cut and paste the bible a couple of times and stick it in your form.

Even if you do specify the MAXLENGTH to a reasonable number make sure you double check the length of the submitted data on the server before processing (using something like php or asp) as it's quite easy to get around the basic MAXLENGTH restriction anyway

The technical part has been well-covered in the other answers, and it mainly ends in:
"He is wrong, he doesn't know stuff, ask him to join SO and get it all cleared :)"

I would like to address the fact(which has been mentioned in other answers) that this might be a stress-question and is an important tool for many interviewers to know more about you and how do you react to difficult and unusual situations. By giving you incorrect codes, he probably wanted to see if you argued back. To know whether you have the confidence to stand up against your seniors in situations similar to this.

P.S: I don't know why but I have a feeling that the interviewer has read this post.

On android 2.2 you can input multiple language and switch by sliding on the spacebar. Go in the settings under "language and keyboard" and then "Android Keyboard", "Input language".

Hope this helps.

I had the same issue, unable to resize the image when adjusting browser dimensions.

Bad Code:

html {  
  background-color: white;  
  background-image: url("example.png");  
  background-repeat: no-repeat;  
  background-attachment: scroll;  
  background-position: 0% 0%;
}

Good Code:

html {  
  background-color: white;  
  background-image: url("example.png");  
  background-repeat: no-repeat;  
  background-attachment: scroll;  
  background-position: 0% 0%;
  background-size: contain;
}

The key here is the addition of this element -> background-size: contain;

import java.util.ArrayList;
import java.util.List;

class ArrLst{

    public static void main(String args[]){

        List l=new ArrayList();
        l.add(10);
        l.add(11);
        l.add(12);
        l.add(13);
        l.add(14);
        l.forEach((a)->System.out.println(a));
    }
}

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.

If your list is very big and you are filtering repeatedly - you can sort the original list on the filter attribute, binary search to find the start and end points.

Initial time O(n*log(n)) then O(log(n)).

Standard filtering will take O(n) each time.

Be careful using SelectedItem.Text... If there is no item selected, then SelectedItem will be null and SelectedItem.Text will generate a null-value exception.

.NET should have provided a SelectedText property like the SelectedValue property that returns String.Empty when there is no selected item.

Today NodeJS supports new async/await syntax. This is an easy syntax and makes the life much easier

async function process(promises) { // must be an async function
    let x = await Promise.all(promises);  // now x will be an array
    x = x.map( tmp => tmp * 10);              // proccessing the data.
}

const promises = [
   new Promise(resolve => setTimeout(resolve, 0, 1)),
   new Promise(resolve => setTimeout(resolve, 0, 2))
];

process(promises)

Resolved this problem using a Sequence ID defined in Oracle database.

ORACLE_DB_SEQ_ID is defined as a sequence for the table. Also look at the console to see the Hibernate SQL that is used to verify.

@Id
@Column(name = "MY_ID", unique = true, nullable = false)
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator = "id_Sequence")
@SequenceGenerator(name = "id_Sequence", sequenceName = "ORACLE_DB_SEQ_ID")
Long myId;

The simple way to do it. All you need is to put the decorator method outside the class. You can still use it inside.

def my_decorator(func):
    #this is the key line. There's the aditional self parameter
    def wrap(self, *params, **kwargs):
        # you can use self here as if you were inside the class
        return func()
    return wrap

class Test(object):
    @my_decorator
    def bar(self):
        pass

I always use this link to see what type is the number I get with type():

You can show changes that have been staged with the --cached flag:

$ git diff --cached

In more recent versions of git, you can also use the --staged flag (--staged is a synonym for --cached):

$ git diff --staged

I was getting the same issue with a different application,

Faulting application name: javaw.exe, version: 8.0.51.16, time stamp: 0x55763d32
Faulting module name: mscorwks.dll, version: 2.0.50727.5485, time stamp: 0x53a11d6c
Exception code: 0xc0000005
Fault offset: 0x0000000000501090

Faulting module path:C:\Windows\Microsoft.NET\Framework64\v2.0.50727\mscorwks.dll

I was using the The Enhanced Mitigation Experience Toolkit (EMET) from Microsoft and I found by disabling the EMET features on javaw.exe in my case as this was the faulting application, it enabled my application to run successfully. Make sure you don't have any similar software with security protections on memory.

You can use indexOf But not working well in the last version of internet explorer. Code:

function isInArray(value, array) {
  return array.indexOf(value) > -1;
}

Execution:

isInArray(1, [1,2,3]); // true

I suggest you use the following code:

function inArray(needle, haystack) {
 var length = haystack.length;
 for (var i = 0; i < length; i++) {
 if (haystack[i] == needle)
  return true;
 }
 return false;
}

Use Built-in format() function and int() function It's simple and easy to understand. It's little bit simplified version of Aaron answer

int()

int(string, base)

format()

format(integer, # of bits)

Example

# w/o 0b prefix
>> format(int("ABC123EFFF", 16), "040b")
1010101111000001001000111110111111111111

# with 0b prefix
>> format(int("ABC123EFFF", 16), "#042b")
0b1010101111000001001000111110111111111111

# w/o 0b prefix + 64bit
>> format(int("ABC123EFFF", 16), "064b")
0000000000000000000000001010101111000001001000111110111111111111

Split on your separator at most once, and take the first piece:

sep = '...'
stripped = text.split(sep, 1)[0]

You didn't say what should happen if the separator isn't present. Both this and Alex's solution will return the entire string in that case.

Use the pandas.DataFrame.round() method like this:

df = df.round({'value1': 0})

Any columns not included will be left as is.

Although the following line is taken from a windows batch script, the command should be quite similar:

psql -U username -h localhost -d postgres -c "DROP DATABASE \"$DATABASE\";"

This command is used to clear the whole database, by actually dropping it. The $DATABASE (in Windows should be %DATABASE%) in the command is a windows style environment variable that evaluates to the database name. You will need to substitute that by your development_db_name.

I got the same question here. If the document is huge, it is not a good idea to use XmlDocument. The fact is that the first element is the root element, based on which XmlReader can be used to get the root element. Using XmlReader will be much more efficient than using XmlDocument as it doesn't require load the whole document into memory.

  using (XmlReader reader = XmlReader.Create(<your_xml_file>)) {
    while (reader.Read()) {
      // first element is the root element
      if (reader.NodeType == XmlNodeType.Element) {
        System.Console.WriteLine(reader.Name);
        break;
      }
    }
  }

The best practice is to keep your HTML and CSS separate for less code duplication, and for separation of concerns (HTML for structure and semantics, and CSS for presentation).

Note that, for this to work in older versions of Internet Explorer, you may have to give your table a specific width (e.g., 900px). That browser has some problems rendering an element with percentage dimensions if its wrapper doesn't have exact dimensions.

Oops. Original answer was specific to a similar question. This has been revised:

var canvas = document.getElementById("mycanvas");
var img    = canvas.toDataURL("image/png");

with the value in IMG you can write it out as a new Image like so:

document.write('<img src="'+img+'"/>');

Portable HttpClient for .NET Framework and Windows Phone

Like this its work if you want to parse some string which is coming from mYearInDB.toString() =[2013] it will give 2013

Matcher n = MY_PATTERN.matcher("FOO[BAR]"+mYearInDB.toString());
while (n.find()) {
 extracredYear  = n.group(1);
 // s now contains "BAR"
    }
    System.out.println("Extrated output is : "+extracredYear);

The ENABLEDELAYEDEXPANSION part is REQUIRED in certain programs that use delayed expansion, that is, that takes the value of variables that were modified inside IF or FOR commands by enclosing their names in exclamation-marks.

If you enable this expansion in a script that does not require it, the script behaves different only if it contains names enclosed in exclamation-marks !LIKE! !THESE!. Usually the name is just erased, but if a variable with the same name exist by chance, then the result is unpredictable and depends on the value of such variable and the place where it appears.

The SETLOCAL part is REQUIRED in just a few specialized (recursive) programs, but is commonly used when you want to be sure to not modify any existent variable with the same name by chance or if you want to automatically delete all the variables used in your program. However, because there is not a separate command to enable the delayed expansion, programs that require this must also include the SETLOCAL part.

Supose you have the following scenario:

* 1bd2200 (HEAD, master) another commit
* d258546 bad commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit

Where you want to remove d258546 i.e. "bad commit".

You shall try an interactive rebase to remove it: git rebase -i 34c4f95

then your default editor will pop with something like this:

 pick bd8aa13 2nd commit
 pick 0f1efa9 3rd commit
 pick d258546 bad commit
 pick 1bd2200 another commit

 # Rebase 34c4f95..1bd2200 onto 34c4f95
 #
 # Commands:
 #  p, pick = use commit
 #  r, reword = use commit, but edit the commit message
 #  e, edit = use commit, but stop for amending
 #  s, squash = use commit, but meld into previous commit
 #  f, fixup = like "squash", but discard this commit's log message
 #  x, exec = run command (the rest of the line) using shell
 #
 # These lines can be re-ordered; they are executed from top to bottom.
 #
 # If you remove a line here THAT COMMIT WILL BE LOST.
 #
 # However, if you remove everything, the rebase will be aborted.
 #
 # Note that empty commits are commented out

just remove the line with the commit you want to strip and save+exit the editor:

 pick bd8aa13 2nd commit
 pick 0f1efa9 3rd commit
 pick 1bd2200 another commit
 ...

git will proceed to remove this commit from your history leaving something like this (mind the hash change in the commits descendant from the removed commit):

 * 34fa994 (HEAD, master) another commit
 * 0f1efa9 3rd commit
 * bd8aa13 2nd commit
 * 34c4f95 1st commit

Now, since I suppose that you already pushed the bad commit to gitlab, you'll need to repush your graph to the repository (but with the -f option to prevent it from being rejected due to a non fastforwardeable history i.e. git push -f <your remote> <your branch>)

Please be extra careful and make sure that none coworker is already using the history containing the "bad commit" in their branches.

Alternative option:

Instead of rewrite the history, you may simply create a new commit which negates the changes introduced by your bad commit, to do this just type git revert <your bad commit hash>. This option is maybe not as clean, but is far more safe (in case you are not fully aware of what are you doing with an interactive rebase).

As already stated, screen -S SESSIONTITLE works for starting a session with a title (SESSIONTITLE), but if you start a session and later decide to change its title. This can be accomplished by using the default key bindings:

Ctrl+a, A

Which prompts:

Set windows title to:SESSIONTITLE

Change SESSIONTITLE by backspacing and typing in the desired title. To confirm the name change and list all titles.

Ctrl+a, "

using slice, apply and join method.

You can select the rows from the table you want to export in the MySQL Workbench SQL Editor. You will find an Export button in the resultset that will allow you to export the records to a CSV file, as shown in the following image:

Please also keep in mind that by default MySQL Workbench limits the size of the resultset to 1000 records. You can easily change that in the Preferences dialog:

Hope this helps.

Once you have Selected a group of sheets, you can use Selection

Consider:

Sub luxation()
    ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
    Selection.ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:="C:\TestFolder\temp.pdf", _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=True
End Sub

EDIT#1:

Further testing has reveled that this technique depends on the group of cells selected on each worksheet. To get a comprehensive output, use something like:

Sub Macro1()

   Sheets("Sheet1").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet2").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet3").Activate
   ActiveSheet.UsedRange.Select

   ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
   Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
      "C:\Users\James\Desktop\pdfmaker.pdf", Quality:=xlQualityStandard, _
      IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
      True
End Sub

SELECT Cast(Round(123.456,2,1) as decimal(18,2))

This also works....sometimes you may want to construct the definition of the parameters outside of the actual EXEC call.

DECLARE @Parmdef nvarchar (500)
DECLARE @SQL nvarchar (max)
DECLARE @xTxt1  nvarchar (100) = 'test1'
DECLARE @xTxt2  nvarchar (500) = 'test2' 
SET @parmdef = '@text1 nvarchar (100), @text2 nvarchar (500)'
SET @SQL = 'PRINT @text1 + '' '' + @text2'
EXEC sp_executeSQL @SQL, @Parmdef, @xTxt1, @xTxt2

Adding to the solutions of others, I'd like to suggest using the plotly package for R, as this has worked well for me.

Below, I'm using the reformatted dataset suggested above, from xyz-tripplets to axis vectors x and y and a matrix z:

x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z

library(plotly)
plot_ly(x=x,y=y,z=z, type="surface")

The rendered surface can be rotated and scaled using the mouse. This works fairly well in RStudio.

You can also try it with the built-in volcano dataset from R:

plot_ly(z=volcano, type="surface")

var nvc = new List<KeyValuePair<string, string>>();
nvc.Add(new KeyValuePair<string, string>("Input1", "TEST2"));
nvc.Add(new KeyValuePair<string, string>("Input2", "TEST2"));
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, url) { Content = new FormUrlEncodedContent(nvc) };
var res = await client.SendAsync(req);

Or

var dict = new Dictionary<string, string>();
dict.Add("Input1", "TEST2");
dict.Add("Input2", "TEST2");
var client = new HttpClient();
var req = new HttpRequestMessage(HttpMethod.Post, url) { Content = new FormUrlEncodedContent(dict) };
var res = await client.SendAsync(req);

I add a picture, show configdifference between mirror and bare. The left is bare, right is mirror. You can be clear, mirror's config file have fetch key, which means you can update it,by git remote update or git fetch --all

Although ANSI C does not have this mechanism, it is possible to use itoa() as a shortcut:

  char buffer [33];
  itoa (i,buffer,2);
  printf ("binary: %s\n",buffer);

Here's the origin:

itoa in cplusplus reference

It is non-standard C, but K&R mentioned the implementation in the C book, so it should be quite common. It should be in stdlib.h.

You can use a $ sign like:

OUTPUT=$(expression)

You should not pass the call function hi() to the loop() function, This will give the result.

def hi():     
  print('hi')

def loop(f, n):         #f repeats n times
  if n<=0:
    return
  else:
    f()             
    loop(f, n-1)    

loop(hi, 5)            # Do not use hi() function inside loop() function

<div id="foo">hello world!</div>
<img src="zoom.png" id="click_me" />

JS

$('#click_me').click(function(){
  $('#foo').css({
    'background-color':'red',
    'color':'white',
    'font-size':'44px'
  });
});

Get client ip using command:

request.remote_ip

Try:

trunc(Months_Between(date2, date1))

You simply have to pipe an iconv command before the sed command. Ex with file.txt input :

iconv -f ISO-8859-1 -t UTF8-MAC file.txt | sed 's/something/àéèêçùû/g' | .....

-f option is the 'from' codeset and -t option is the 'to' codeset conversion.

Take care of case, web pages usually show lowercase like that < charset=iso-8859-1"/> and iconv uses uppercase. You have list of iconv supported codesets in you system with command iconv -l

UTF8-MAC is modern OS Mac codeset for conversion.

Your life will be much easier if you can save a List as the value instead of an array in that Map.

To remove the decimals from your double, take a look at this output

Obj C

double hellodouble = 10.025;
NSLog(@"Your value with 2 decimals: %.2f", hellodouble);
NSLog(@"Your value with no decimals: %.0f", hellodouble);

The output will be:

10.02 
10

Swift 2.1 and Xcode 7.2.1

let hellodouble:Double = 3.14159265358979
print(String(format:"Your value with 2 decimals: %.2f", hellodouble))
print(String(format:"Your value with no decimals: %.0f", hellodouble))

The output will be:

3.14 
3

If we use=> .equals method

if(obj.equals(null))  

// Which mean null.equals(null) when obj will be null.

When your obj will be null it will throw Null Point Exception.

so we should use ==

if(obj == null)

it will compare the references.

Had a similar issue, and tried lots of things. Ultimately what worked for me, was to have Gnu on Windows installed (https://github.com/bmatzelle/gow/releases) , and ensure that it was using the ssh tool inside that directory and not the one with Git. Once installed test with (ensure if its in your environment PATH that it preceds Git\bin)

C:\Git\htest2>which ssh
C:\Program Files (x86)\Gow\bin\ssh.BAT

I used putty and pageant as described here:http://rubyonrailswin.wordpress.com/2010/03/08/getting-git-to-work-on-heroku-on-windows-using-putty-plink-pageant/

Once the keys had been sent to heroku (heroku keys:add c:\Users\Person.ssh\id_rsa.pub), use

ssh -v <username>@heroku.com 

and ensure that your stack is showing use of Putty - ie a working stack:

If it does not solve your problem then check whether your XML files are not open by another thread using these configuration files.. and provide some more details if still persists.

There's nothing wrong with either version of your code. Whatever is causing this, that's not it.

Have you triple checked your locator? Your element definitely has name=submit not id=submit?

Best way would be to declare Boolean variable within the code block and return it at end of code, like this:

public boolean Test(){
    boolean booleanFlag= true; 
    if (A>B)
    {booleanFlag= true;}
    else 
    {booleanFlag = false;}
    return booleanFlag;

}

I find this the best way.

If you are creating a mock-up with SoapUI,a free testing tool for REST and SOAP request and response, for Angular 2+ application you should remember to set inside your http header request

 Access-Control-Allow-Origin :  *

I add two images for helping your insert. The first shows the header you should add. If you want to add the header before you have to click the plus button(it's green).

The second image shows the insert the *. The value * permits to accept all the request from different hosts.

After this work my Angular application removed this annoying error in my console.

A big recourse that helped me to understand for creating my first mock up is this video. It will help you for creating a new mock-up inside SoapUi's environment without a server-side.

I would like to transmit it as byte[] over sockets to another machine

// When you connect
ObjectOutputStream oos = new ObjectOutputStream(socket.getOutputStream());
// When you want to send it
oos.writeObject(appMessage);

where it is rebuilt from the bytes received.

// When you connect
ObjectInputStream ois = new ObjectInputStream(socket.getInputStream());
// When you want to receive it
AppMessage appMessage = (AppMessage)ois.readObject();

You can try this way:

self.classForCoder.description()

My utils function for get view location, it will return a Point object with x value and y value

public static Point getLocationOnScreen(View view){
    int[] location = new int[2];
    view.getLocationOnScreen(location);
    return new Point(location[0], location[1]);
}

Using

Point viewALocation = getLocationOnScreen(viewA);

I know this is a little bit too late but it might just help someone.

In my case I already had a method to make the Object from a json Object and make json from the object. with this you can simply create a new instance of the object and use it to restore. For instance in a function parsing a final object

public void update(final Object object){ _x000D_
  final Object original = Object.makeFromJSON(object.toJSON()); _x000D_
  // the original is not affected by changes made to object _x000D_
}

Additionally, how do I retrieve the number of days of a given month?

Aside from calculating it yourself (and consequently having to get leap years right), you can use a Date calculation to do it:

var y= 2010, m= 11;            // December 2010 - trap: months are 0-based in JS

var next= Date.UTC(y, m+1);    // timestamp of beginning of following month
var end= new Date(next-1);     // date for last second of this month
var lastday= end.getUTCDate(); // 31

In general for timestamp/date calculations I'd recommend using the UTC-based methods of Date, like getUTCSeconds instead of getSeconds(), and Date.UTC to get a timestamp from a UTC date, rather than new Date(y, m), so you don't have to worry about the possibility of weird time discontinuities where timezone rules change.

With Linq

var newList = GlobalStrings.Append(localStrings)

Probably rather than defining both the events click and touch you could define a an handler which will look if the device will work with click or touch.

var handleClick= 'ontouchstart' in document.documentElement ? 'touchstart': 'click';
$(document).on(handleClick,'.button',function(){
alert('Click is now working with touch and click both');
});

You can use random access.

Open "C:\docs\TESTFILE.txt" For Random As #1 

    Position = 3    ' Define record number.
    Get #1, Position, ARecord    ' Read record.

Close #1

This would get all files in path/to/files with an .swf extension into an array and then sort that array by the file's mtime

$files = glob('path/to/files/*.swf');
usort($files, function($a, $b) {
    return filemtime($b) - filemtime($a);
});

The above uses an Lambda function and requires PHP 5.3. Prior to 5.3, you would do

usort($files, create_function('$a,$b', 'return filemtime($b)-filemtime($a);'));

If you don't want to use an anonymous function, you can just as well define the callback as a regular function and pass the function name to usort instead.

With the resulting array, you would then iterate over the files like this:

foreach($files as $file){
    printf('<tr><td><input type="checkbox" name="box[]"></td>
            <td><a href="%1$s" target="_blank">%1$s</a></td>
            <td>%2$s</td></tr>', 
            $file, // or basename($file) for just the filename w\out path
            date('F d Y, H:i:s', filemtime($file)));
}

Note that because you already called filemtime when sorting the files, there is no additional cost when calling it again in the foreach loop due to the stat cache.

A directive allows you to extend the HTML vocabulary in a declarative fashion for building web components. The ng-app attribute is a directive, so is ng-controller and all of the ng- prefixed attributes. Directives can be attributes, tags or even class names, comments.

How directives are born (compilation and instantiation)

Compile: We’ll use the compile function to both manipulate the DOM before it’s rendered and return a link function (that will handle the linking for us). This also is the place to put any methods that need to be shared around with all of the instances of this directive.

link: We’ll use the link function to register all listeners on a specific DOM element (that’s cloned from the template) and set up our bindings to the page.

If set in the compile() function they would only have been set once (which is often what you want). If set in the link() function they would be set every time the HTML element is bound to data in the object.

<div ng-repeat="i in [0,1,2]">
    <simple>
        <div>Inner content</div>
    </simple>
</div>

app.directive("simple", function(){
   return {
     restrict: "EA",
     transclude:true,
     template:"<div>{{label}}<div ng-transclude></div></div>",        
     compile: function(element, attributes){  
     return {
             pre: function(scope, element, attributes, controller, transcludeFn){

             },
             post: function(scope, element, attributes, controller, transcludeFn){

             }
         }
     },
     controller: function($scope){

     }
   };
});

Compile function returns the pre and post link function. In the pre link function we have the instance template and also the scope from the controller, but yet the template is not bound to scope and still don't have transcluded content.

Post link function is where post link is the last function to execute. Now the transclusion is complete, the template is linked to a scope, and the view will update with data bound values after the next digest cycle. The link option is just a shortcut to setting up a post-link function.

controller: The directive controller can be passed to another directive linking/compiling phase. It can be injected into other directices as a mean to use in inter-directive communication.

You have to specify the name of the directive to be required – It should be bound to same element or its parent. The name can be prefixed with:

? – Will not raise any error if a mentioned directive does not exist.
^ – Will look for the directive on parent elements, if not available on the same element.

Use square bracket [‘directive1', ‘directive2', ‘directive3'] to require multiple directives controller.

var app = angular.module('app', []);

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

app.directive('parentDirective', function() {
  return {
    restrict: 'E',
    template: '<child-directive></child-directive>',
    controller: function($scope, $element){
      this.variable = "Hi Vinothbabu"
    }
  }
});

app.directive('childDirective', function() {
  return {
    restrict:  'E',
    template: '<h1>I am child</h1>',
    replace: true,
    require: '^parentDirective',
    link: function($scope, $element, attr, parentDirectCtrl){
      //you now have access to parentDirectCtrl.variable
    }
  }
});

The common convention would be to put it in a .sh file that looks like this -

#!/bin/bash
java -cp  ".;./supportlibraries/Framework_Core.jar;... etc

Note that '\' become '/'.

You could execute as

sh myfile.sh

or set the x bit on the file

chmod +x myfile.sh

and then just call

myfile.sh

I installed PyLint but I was having the error Missing module docstringpylint(missing-module-docstring). So I found this answer with this config for pylint :

"python.linting.pylintEnabled": true,
"python.linting.pylintArgs": [
    "--disable=C0111", // missing docstring
    "--load-plugins=pylint_django,pylint_celery",
 ],

And now it works

The solution is simple, just use the CascadeType.MERGE instead of CascadeType.PERSIST or CascadeType.ALL.

I have had the same problem and CascadeType.MERGE has worked for me.

I hope you are sorted.

I Using below simple way to create a project 1- First in a directory that desire to make it project, create a .project file with below contents:

<projectDescription>
    <name>Project-Name</name>
    <comment></comment>
    <projects>
    </projects>
    <buildSpec>
    </buildSpec>
    <natures>
    </natures>
</projectDescription>

2- Now instead of "Project-Name", write your project name, maybe current directory name

3- Now save this file to directory that desire to make that directory as project with name ".project" ( for save like this, use Notepad )

4- Now go to Eclips and open project and add your files to it.

In addition, you can use the "&" sign to run many processes through one (1) ssh connections in order to to keep minimum number of terminals. For example, I have one process that listens for messages in order to extract files, the second process listens for messages in order to upload files: Using the "&" I can run both services in one terminal, through single ssh connection to my server.


*****I just realized that these processes running through the "&" will also "stay alive" after ssh session is closed! pretty neat and useful if your connection to the server is interrupted**

I found a much easier way and I hope it works for you. (using Windows 10 and Excel 2016)

Create a new module and enter the following code: Sub auto_open() 'Macro to be run (doesn't have to be in this module, just in this workbook End Sub

Set up a task through the Task Scheduler and set the "program to be run as" Excel (found mine at C:\Program Files (x86)\Microsoft Office\root\Office16). Then set the "Add arguments (optional): as the file path to the macro-enabled workbook. Remember that both the path to Excel and the path to the workbook should be in double quotes.

*See example from Rich, edited by Community, for an image of the windows scheduler screen.

This happened to me when I tried to git pull. Some analysis showed that somebody had commited with root in the past, thereby creating some objects with root ownership in .git/objects.

So I ran

cd <repo>
la .git/objects/

and that showed root ownership for some objects (directories) like this:

user@host:/repo> la .git/objects/
total 540
drwxr-xr-x 135 user user 4096 Jun 16 16:29 .
drwxr-xr-x   8 user user 4096 Jun 16 16:33 ..
drwxr-xr-x   2 user user 4096 Mar  1 17:28 01
drwxr-xr-x   2 user user 4096 Mar  1 17:28 02
drwxr-xr-x   2 user user 4096 Jun 16 16:27 03
drwxr-xr-x   2 user user 4096 Mar  3 13:22 04
drwxr-xr-x   2 root root 4096 Jun 16 16:29 05
drwxr-xr-x   2 user user 4096 Jun 16 16:28 07
drwxr-xr-x   2 root root 4096 Jun 16 16:29 08

Then I ran

sudo chown -R user:user .git/objects/

and it worked!

I was replacing user with my real user, of course.

You can use the SimpleDateFormat class:

SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String format = s.format(new Date());

hasClass function:

HTMLElement.prototype.hasClass = function(cls) {
    var i;
    var classes = this.className.split(" ");
    for(i = 0; i < classes.length; i++) {
        if(classes[i] == cls) {
            return true;
        }
    }
    return false;
};

addClass function:

HTMLElement.prototype.addClass = function(add) {
    if (!this.hasClass(add)){
        this.className = (this.className + " " + add).trim();
    }
};

removeClass function:

HTMLElement.prototype.removeClass = function(remove) {
    var newClassName = "";
    var i;
    var classes = this.className.replace(/\s{2,}/g, ' ').split(" ");
    for(i = 0; i < classes.length; i++) {
        if(classes[i] !== remove) {
            newClassName += classes[i] + " ";
        }
    }
    this.className = newClassName.trim();
};

Second case is also inefficient in terms of String pool, you have to explicitly call intern() on return reference to make it intern.

Pretty self explanatory.

repeat{
  statements...
  if(condition){
    break
  }
}

Or something like that I would think. To get the effect of the do while loop, simply check for your condition at the end of the group of statements.

Convert your data to a data.table and use set by reference and row filtering

library(data.table)

dt <- as.data.table(your.dataframe.or.whatever)
dt[, is.1957 := 0]
dt[year == 1957, is.1957 := 1]

Proof-of-concept toy example:

library(data.table)

dt <- as.data.table(cbind(c(1, 1, 1), c(2, 2, 3)))
dt[, is.3 := 0]
dt[V2 == 3, is.3 := 1]

This is similar to the answer mplungjan referenced from another post, but more concise:

const secs = 456;_x000D_
_x000D_
const formatted = moment.utc(secs*1000).format('HH:mm:ss');_x000D_
_x000D_
document.write(formatted);

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

It suffers from the same caveats, e.g. if seconds exceed one day (86400), you'll not get what you expect.

Alternatively you can use the classmethod decorator:

class A:
    @classmethod
    def get_classname(cls):
        return cls.__name__

    def use_classname(self):
        return self.get_classname()

Usage:

>>> A.get_classname()
'A'
>>> a = A()
>>> a.get_classname()
'A'
>>> a.use_classname()
'A'

false == 0 and true = !false

i.e. anything that is not zero and can be converted to a boolean is not false, thus it must be true.

Some examples to clarify:

if(0)          // false
if(1)          // true
if(2)          // true
if(0 == false) // true
if(0 == true)  // false
if(1 == false) // false
if(1 == true)  // true
if(2 == false) // false
if(2 == true)  // false
cout << false  // 0
cout << true   // 1

true evaluates to 1, but any int that is not false (i.e. 0) evaluates to true but is not equal to true since it isn't equal to 1.

I had this issue and found a much simpler solution than using a ByteArrayResource.

Simply do

public void loadInvoices(MultipartFile invoices, String channel) throws IOException {

    init();

    Resource invoicesResource = invoices.getResource();

    LinkedMultiValueMap<String, Object> parts = new LinkedMultiValueMap<>();
    parts.add("file", invoicesResource);

    HttpHeaders httpHeaders = new HttpHeaders();
    httpHeaders.setContentType(MediaType.MULTIPART_FORM_DATA);
    httpHeaders.set("channel", channel);

    HttpEntity<LinkedMultiValueMap<String, Object>> httpEntity = new HttpEntity<>(parts, httpHeaders);

    String url = String.format("%s/rest/inbound/invoices/upload", baseUrl);

    restTemplate.postForEntity(url, httpEntity, JobData.class);
}

It works, and no messing around with the file system or byte arrays.

you just need to add disabled at the end

<input type="text" value="3" class="field left" disabled>

If you use the gson.JsonObject you can have something like that:

import com.google.gson.JsonObject;
import com.google.gson.JsonParser;

String jsonString = "{'test1':'value1','test2':{'id':0,'name':'testName'}}"
JsonObject jsonObject = (JsonObject) jsonParser.parse(jsonString)

Unfortunately I ran into the same issue and I was head scratching why this is happening. I almost tried everything on this page and but none worked for me.

So , I tried to go the root of this problem; and the problem was (Atleast for me) that I was trying to open a maven project but pom file was not identified. So right clicking on the pom file and choosing "add as maven project" and then right clicking on the project -> Maven -> Reimport did all the magic for me :)

Hopefully this can be helpful for someone.

The Guava library contains convenience methods for creating lists and other collections which makes this much prettier than using the standard library classes.

Example:

ArrayList<String> list = newArrayList("a", "b", "c");

(This assumes import static com.google.common.collect.Lists.newArrayList;)
