For such companies as google, amazon etc, whose servers are running at max capacity in 24/7-mode, reducing traffic means real money - less hardware, less energy, less maintenance. Shifting CPU-usage from server to client pays off, and SPAs shine. The advantages overweight disadvantages by far. So, SPA or not SPA depends much on the use case.

Just for mentioning another, probably not so obvious (for Web-developers) use case for SPAs: I'm currently looking for a way to implement GUIs in embedded systems and browser-based architecture seems appealing to me. Traditionally there were not many possibilities for UIs in embedded systems - Java, Qt, wx, etc or propriety commercial frameworks. Some years ago Adobe tried to enter the market with flash but seems to be not so successful.

Nowadays, as "embedded systems" are as powerful as mainframes some years ago, a browser-based UI connected to the control unit via REST is a possible solution. The advantage is, the huge palette of tools for UI for no cost. (e.g. Qt require 20-30$ per sold unit on royalty fees plus 3000-4000$ per developer)

For such architecture SPA offers many advantages - e.g. more familiar development-approach for desktop-app developers, reduced server access (often in car-industry the UI and system muddles are separate hardware, where the system-part has an RT OS).

As the only client is the built-in browser, the mentioned disadvantages like JS-availability, server-side logging, security don't count any more.

A good reason, which you have sort of touched on, is that once the CSRF cookie has been received, it is then available for use throughout the application in client script for use in both regular forms and AJAX POSTs. This will make sense in a JavaScript heavy application such as one employed by AngularJS (using AngularJS doesn't require that the application will be a single page app, so it would be useful where state needs to flow between different page requests where the CSRF value cannot normally persist in the browser).

Consider the following scenarios and processes in a typical application for some pros and cons of each approach you describe. These are based on the Synchronizer Token Pattern.

Request Body Approach

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it to a hidden field.
5. User submits form.
6. Server checks hidden field matches session stored token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Cookie can actually be HTTP Only.

Disadvantages:

• All forms must output the hidden field in HTML.
• Any AJAX POSTs must also include the value.
• The page must know in advance that it requires the CSRF token so it can include it in the page content so all pages must contain the token value somewhere, which could make it time consuming to implement for a large site.

Custom HTTP Header (downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form (token is sent via hidden field).
7. Server checks hidden field matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work without an AJAX request to get the header value.
• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CSRF token, so it will mean an extra round trip each time.
• Might as well have simply output the token to the page which would save the extra request.

Custom HTTP Header (upstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it in the page content somewhere.
5. User submits form via AJAX (token is sent via header).
6. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must include the header.

Custom HTTP Header (upstream & downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form via AJAX (token is sent via header) .
7. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CRSF token, so it will mean an extra round trip each time.

Set-Cookie

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Server generates CSRF token, stores it against the user session and outputs it to a cookie.
5. User submits form via AJAX or via HTML form.
6. Server checks custom header (or hidden form field) matches session stored token.
7. Cookie is available in browser for use in additional AJAX and form requests without additional requests to server to retrieve the CSRF token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Doesn't necessarily require an AJAX request to get the cookie value. Any HTTP request can retrieve it and it can be appended to all forms/AJAX requests via JavaScript.
• Once the CSRF token has been retrieved, as it is stored in a cookie the value can be reused without additional requests.

Disadvantages:

• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The cookie will be submitted for every request (i.e. all GETs for images, CSS, JS, etc, that are not involved in the CSRF process) increasing request size.
• Cookie cannot be HTTP Only.

So the cookie approach is fairly dynamic offering an easy way to retrieve the cookie value (any HTTP request) and to use it (JS can add the value to any form automatically and it can be employed in AJAX requests either as a header or as a form value). Once the CSRF token has been received for the session, there is no need to regenerate it as an attacker employing a CSRF exploit has no method of retrieving this token. If a malicious user tries to read the user's CSRF token in any of the above methods then this will be prevented by the Same Origin Policy. If a malicious user tries to retrieve the CSRF token server side (e.g. via curl) then this token will not be associated to the same user account as the victim's auth session cookie will be missing from the request (it would be the attacker's - therefore it won't be associated server side with the victim's session).

As well as the Synchronizer Token Pattern there is also the Double Submit Cookie CSRF prevention method, which of course uses cookies to store a type of CSRF token. This is easier to implement as it does not require any server side state for the CSRF token. The CSRF token in fact could be the standard authentication cookie when using this method, and this value is submitted via cookies as usual with the request, but the value is also repeated in either a hidden field or header, of which an attacker cannot replicate as they cannot read the value in the first place. It would be recommended to choose another cookie however, other than the authentication cookie so that the authentication cookie can be secured by being marked HttpOnly. So this is another common reason why you'd find CSRF prevention using a cookie based method.

I ran into a similar situation trying to convert a table with several 100k rows with a C++ program (MFC/ODBC).

Since this operation took a very long time, I figured bundling multiple inserts into one (up to 1000 due to MSSQL limitations). My guess that a lot of single insert statements would create an overhead similar to what is described here.

However, it turns out that the conversion took actually quite a bit longer:

        Method 1       Method 2     Method 3 
        Single Insert  Multi Insert Joined Inserts
Rows    1000           1000         1000
Insert  390 ms         765 ms       270 ms
per Row 0.390 ms       0.765 ms     0.27 ms

So, 1000 single calls to CDatabase::ExecuteSql each with a single INSERT statement (method 1) are roughly twice as fast as a single call to CDatabase::ExecuteSql with a multi-line INSERT statement with 1000 value tuples (method 2).

Update: So, the next thing I tried was to bundle 1000 separate INSERT statements into a single string and have the server execute that (method 3). It turns out this is even a bit faster than method 1.

Edit: I am using Microsoft SQL Server Express Edition (64-bit) v10.0.2531.0

Firstly, as Etienne says, float in C# is Single. It is just the C# keyword for that data type.

So you can definitely do this:

float f = 13.5f;
string s = f.ToString("R");

Secondly, you have referred a couple of times to the number's "format"; numbers don't have formats, they only have values. Strings have formats. Which makes me wonder: what is this thing you have that has a format but is not a string? The closest thing I can think of would be decimal, which does maintain its own precision; however, calling simply decimal.ToString should have the effect you want in that case.

How about including some example code so we can see exactly what you're doing, and why it isn't achieving what you want?

Alternatively, you may also use the composite operator F then indicating how many decimal spots you wish to appear after the decimal.

string.Format("{0:F2}", 123.456789);     //123.46
string.Format("{0:F3}", 123.456789);     //123.457
string.Format("{0:F4}", 123.456789);     //123.4568

It will round up so be aware of that.

I sourced the general documentation. There are a ton of other formatting operators there as well that you may check out.

Source: https://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.110).aspx

This page on MSDN lists standard DateTime format strings, uncluding strings using the 'Z'.

Update: you will need to make sure that the rest of the date string follows the correct pattern as well (you have not supplied an example of what you send it, so it's hard to say whether you did or not). For the UTC format to work it should look like this:

// yyyy'-'MM'-'dd HH':'mm':'ss'Z'
DateTime utcTime = DateTime.Parse("2009-05-07 08:17:25Z");

Pure JS

window.innerHeight
window.scrollY

is more than 10x faster than jquery (and code has similar size):

Here you can perform test on your machine: https://jsperf.com/window-height-width

Do not use @@fetch_status - this will return status from the last cursor in the current connection. Use the example below:

declare @sqCur cursor;
declare @data varchar(1000);
declare @i int = 0, @lastNum int, @rowNum int;
set @sqCur = cursor local static read_only for 
    select
         row_number() over (order by(select null)) as RowNum
        ,Data -- you fields
    from YourIntTable
open @cur
begin try
    fetch last from @cur into @lastNum, @data
    fetch absolute 1 from @cur into @rowNum, @data --start from the beginning and get first value 
    while @i < @lastNum
    begin
        set @i += 1

        --Do your job here
        print @data

        fetch next from @cur into @rowNum, @data
    end
end try
begin catch
    close @cur      --|
    deallocate @cur --|-remove this 3 lines if you do not throw
    ;throw          --|
end catch
close @cur
deallocate @cur

Try this:

<!-- first page -->
<?php
  session_start(); 
  session_register('myvar');
  $_SESSION['myvar'] == 'myvalue';
?>

<!-- second page -->
<?php
    session_start();
    echo("1");
    if(session_is_registered('myvar'))
    {
        echo("2");
       if($_SESSION['myvar'] == 'myvalue')
       {
           echo("3");
           exit;
       }
    }
    ?>

Best way for Oracle:

With hardcoded datetime:

SELECT TO_CHAR(CAST((FROM_TZ(CAST(TO_DATE('2018-10-27 21:00', 'YYYY-MM-DD HH24:MI') AS TIMESTAMP), 'UTC') AT  TIME ZONE 'EET') AS DATE), 'YYYY-MM-DD HH24:MI') UTC_TO_EET FROM DUAL

Result: 2018-10-28 00:00

With column and table names:

SELECT TO_CHAR(CAST((FROM_TZ(CAST(COLUMN_NAME AS TIMESTAMP), 'UTC') AT  TIME ZONE 'EET') AS DATE), 'YYYY-MM-DD HH24:MI') UTC_TO_EET FROM TABLE_NAME

Java API specifies two methods you could use: indexOf(Object obj) and lastIndexOf(Object obj). The first one returns the index of the element if found, -1 otherwise. The second one returns the last index, that would be like searching the list backwards.

You can create this function to calculate absolute difference between two dates. As I found using DATEDIFF inbuilt system function we will get the difference only in months, days and years. For example : Let say there are two dates 18-Jan-2018 and 15-Jan-2019. So the difference between those dates will be given by DATEDIFF in month as 12 months where as it is actually 11 Months 28 Days. So using the function given below, we can find absolute difference between two dates.

CREATE FUNCTION GetDurationInMonthAndDays(@First_Date DateTime,@Second_Date DateTime)

Create a variable:

var thing1 = undefined;

Declare a Function:

function something1 () {
    return "Hi there, I'm number 1!";
}

Alert the value of thing1 (our first variable):

alert(thing1); // Outputs: "undefined".

Now, if we wanted thing1 to be a reference to the function something1, meaning it would be the same thing as our created function, we would do:

thing1 = something1;

However, if we wanted the return value of the function then we must assign it the return value of the executed function. You execute the function by using parenthesis:

thing1 = something1(); // Value of thing1: "Hi there, I'm number 1!" 

BuildToolsVersion & Dependencies must be same with Base API version.

buildToolsVersion '23.0.2' & compile 

&

com.android.support:appcompat-v7:24.0.0-alpha1

can not match with base API level.

It should be

compile 'com.android.support:appcompat-v7:21.0.3'

Done

You shouldn't be setting the value of the input through refs.

Take a look at the documentation for controlled form components here - https://facebook.github.io/react/docs/forms.html#controlled-components

In a nutshell

<input value={this.state.value} onChange={(e) => this.setState({value: e.target.value})} />

Then you will be able to control the disabled state by using disabled={!this.state.value}

Your strings are JSON formatted, so you will need to parse it into a object. For that you can use JSON.NET.

Here is an example on how to parse a JSON string into a dynamic object:

string source = "{\r\n   \"id\": \"100000280905615\", \r\n \"name\": \"Jerard Jones\",  \r\n   \"first_name\": \"Jerard\", \r\n   \"last_name\": \"Jones\", \r\n   \"link\": \"https://www.facebook.com/Jerard.Jones\", \r\n   \"username\": \"Jerard.Jones\", \r\n   \"gender\": \"female\", \r\n   \"locale\": \"en_US\"\r\n}";
dynamic data = JObject.Parse(source);
Console.WriteLine(data.id);
Console.WriteLine(data.first_name);
Console.WriteLine(data.last_name);
Console.WriteLine(data.gender);
Console.WriteLine(data.locale);

Happy coding!

In ssms we can use GO to execute same statement

Edit This mean if you put

 some query

 GO n

Some query will be executed n times

<script type="text/javascript">_x000D_
        function get_param(param) {_x000D_
   var search = window.location.search.substring(1);_x000D_
   var compareKeyValuePair = function(pair) {_x000D_
      var key_value = pair.split('=');_x000D_
      var decodedKey = decodeURIComponent(key_value[0]);_x000D_
      var decodedValue = decodeURIComponent(key_value[1]);_x000D_
      if(decodedKey == param) return decodedValue;_x000D_
      return null;_x000D_
   };_x000D_
_x000D_
   var comparisonResult = null;_x000D_
_x000D_
   if(search.indexOf('&') > -1) {_x000D_

then in the page i call the values like so:

                                                    </script></td>

this line of code on your terminal, solves the problem

$ sudo chown -R $USER:$USER anaconda 3

If you just want to have an event when a tab is selected, this is the correct way:

<TabControl>
    <TabItem Selector.Selected="OnTabSelected" />
    <TabItem Selector.Selected="OnTabSelected" />
    <TabItem Selector.Selected="OnTabSelected" />
    <!-- You can also catch the unselected event -->
    <TabItem Selector.Unselected="OnTabUnSelected" />
</TabControl>

And in your code

    private void OnTabSelected(object sender, RoutedEventArgs e)
    {
        var tab = sender as TabItem;
        if (tab != null)
        {
            // this tab is selected!
        }
    }

As I know you can't make array without size, but you can use

List<string> l = new List<string>() 

and then l.ToArray().

Depending on the sort order, you can do this :

    int[] array = new int[] { 3, 1, 4, 5, 2 };
    Array.Sort<int>(array,
                    new Comparison<int>(
                            (i1, i2) => i2.CompareTo(i1)
                    ));

... or this :

    int[] array = new int[] { 3, 1, 4, 5, 2 };
    Array.Sort<int>(array,
                    new Comparison<int>(
                            (i1, i2) => i1.CompareTo(i2)
                    ));

i1 and i2 are just reversed.

I wanted to use JavaScript to change a form's action, so I could have different submit inputs within the same form linking to different pages.

I also had the added complication of using Apache rewrite to change example.com/page-name into example.com/index.pl?page=page-name. I found that changing the form's action caused example.com/index.pl (with no page parameter) to be rendered, even though the expected URL (example.com/page-name) was displayed in the address bar.

To get around this, I used JavaScript to insert a hidden field to set the page parameter. I still changed the form's action, just so the address bar displayed the correct URL.

function setAction (element, page)
{
  if(checkCondition(page))
  {
    /* Insert a hidden input into the form to set the page as a parameter.
     */
    var input = document.createElement("input");
    input.setAttribute("type","hidden");
    input.setAttribute("name","page");
    input.setAttribute("value",page);
    element.form.appendChild(input);

    /* Change the form's action. This doesn't chage which page is displayed,
     * it just make the URL look right.
     */
    element.form.action = '/' + page;
    element.form.submit();
  }
}

In the form:

<input type="submit" onclick='setAction(this,"my-page")' value="Click Me!" />

Here are my Apache rewrite rules:

I'd be interested in any explanation as to why just setting the action didn't work.

java: Java application executor which is associated with a console to display output/errors

javaw: (Java windowed) application executor not associated with console. So no display of output/errors. It can be used to silently push the output/errors to text files. It is mostly used to launch GUI-based applications.

javaws: (Java web start) to download and run the distributed web applications. Again, no console is associated.

All are part of JRE and use the same JVM.

Here comes a rather obsqure idea. When every year dividable with 100 gets 365 days, what shall be done at this time? In the far future, when even years dividable with 400 only can get 365 days.

Then there is a possibility or reason to make corrections in years dividable with 80. Normal years will have 365 day and those dividable with 400 can get 366 days. Or is this a loose-loose situation.

I had exactly the same problem. My environment was:

• Spring STS 3.7.3.RELEASE
• Build Id: 201602250940
• Platform: Eclipse Mars.2 (4.5.2)

The symptoms of the problems were:

1. There was a red error flag on my PM file. and the description of the error was as described in the original question asked here.
2. There were known compilation problems in the several Java files in the project, but eclipse still was not showing them flagged as error in the editor pane as well as the project explorer tree on the left side.

The solution (described above) about updating the m2e extensions worked for me.

Better solution (my recommondation):

• update Eclipse m2e extensions
• From Help > Install New Software.., add a new repository (via the Add.. option), pointing to the following URL: https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST/
• Select the m2e extensions, accept the license.
• After update, you will be asked for restarting STS. The problem goes away after STS comes back up.

I know this thread is bit old. But I'm going to post this anyway hoping it might help someone. We can store fields of any Object to shared preference by serializing the object to String. Here I have used GSON for storing any object to shared preference.

Save Object to Preference :

public static void saveObjectToSharedPreference(Context context, String preferenceFileName, String serializedObjectKey, Object object) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(preferenceFileName, 0);
    SharedPreferences.Editor sharedPreferencesEditor = sharedPreferences.edit();
    final Gson gson = new Gson();
    String serializedObject = gson.toJson(object);
    sharedPreferencesEditor.putString(serializedObjectKey, serializedObject);
    sharedPreferencesEditor.apply();
}

Retrieve Object from Preference:

public static <GenericClass> GenericClass getSavedObjectFromPreference(Context context, String preferenceFileName, String preferenceKey, Class<GenericClass> classType) {
    SharedPreferences sharedPreferences = context.getSharedPreferences(preferenceFileName, 0);
    if (sharedPreferences.contains(preferenceKey)) {
        final Gson gson = new Gson();
        return gson.fromJson(sharedPreferences.getString(preferenceKey, ""), classType);
    }
    return null;
}

Note :

Remember to add compile 'com.google.code.gson:gson:2.6.2' to dependencies in your gradle.

Example :

//assume SampleClass exists
SampleClass mObject = new SampleObject();

//to store an object
saveObjectToSharedPreference(context, "mPreference", "mObjectKey", mObject);

//to retrive object stored in preference
mObject = getSavedObjectFromPreference(context, "mPreference", "mObjectKey", SampleClass.class);

Update:

As @Sharp_Edge pointed out in comments, the above solution does not work with List.

A slight modification to the signature of getSavedObjectFromPreference() - from Class<GenericClass> classType to Type classType will make this solution generalized. Modified function signature,

public static <GenericClass> GenericClass getSavedObjectFromPreference(Context context, String preferenceFileName, String preferenceKey, Type classType)

For invoking,

getSavedObjectFromPreference(context, "mPreference", "mObjectKey", (Type) SampleClass.class)

Happy Coding!

For Symfony 2.3+, to get the base url in a controller should be

$this->get('request')->getSchemeAndHttpHost();

The "selected" answer didn't work for me. I'm using rails 3.1 with CouchRest::Model (based on Active Model). The _changed? methods don't return true for changed attributes in the after_update hook, only in the before_update hook. I was able to get it to work using the (new?) around_update hook:

class SomeModel < ActiveRecord::Base
  around_update :send_notification_after_change

  def send_notification_after_change
    should_send_it = self.published_changed? && self.published == true

    yield

    Notification.send(...) if should_send_it
  end

end

set phpmailer to work in debug to see the "real" error behind the generic message 'SMTP Error: data not accepted' in our case the text in the message was triggering the smtp server spam filter.

  $email->SMTPDebug = true;

Add:

  <%= csrf_meta_tag %>  and 
  <%= javascript_include_tag :defaults %>  to layouts

Use these link_to tags

 link_to 'Sign out', destroy_user_session_path, :method => :delete

  or

 link_to 'Sign out', '/users/sign_out', :method => :delete

In routes add:

  devise_for :users do
    get '/users/sign_out' => 'devise/sessions#destroy'
  end

I solved this issue by running cmd as an administrator. before that, I was trying to run in vs code.

run it in Power Shell or Cmd with administrative privilege. I hope that it will help.

npm install –g @angular/cli@latest

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

Here's a simple example using Bootstrap 4 with ChartJs. Use an HTML5 Canvas element for the chart...

<div class="container">
    <div class="row">
        <div class="col-md-6">
            <div class="card">
                <div class="card-body">
                    <canvas id="chLine"></canvas>
                </div>
            </div>
        </div>
     </div>     
</div>

And then the appropriate JS to populate the chart...

var colors = ['#007bff','#28a745'];
var chLine = document.getElementById("chLine");
var chartData = {
  labels: ["S", "M", "T", "W", "T", "F", "S"],
  datasets: [{
    data: [589, 445, 483, 503, 689, 692, 634],
    borderColor: colors[0],
    borderWidth: 4,
    pointBackgroundColor: colors[0]
  },
  {
    data: [639, 465, 493, 478, 589, 632, 674],
    borderColor: colors[1],
    borderWidth: 4,
    pointBackgroundColor: colors[1]
  }]
};
if (chLine) {
  new Chart(chLine, {
  type: 'line',
  data: chartData,
  options: {
    scales: {
      yAxes: [{
        ticks: {
          beginAtZero: false
        }
      }]
    },
    legend: {
      display: false
    }
  }
  });
}

You need to re-parse the form after adding dynamic content in order to validate the content

$('form').data('validator', null);
$.validator.unobtrusive.parse($('form'));

It's strange because @ControllerAdvice should works, are you catching the correct Exception?

@ControllerAdvice
public class GlobalDefaultExceptionHandler {

    @ResponseBody
    @ExceptionHandler(value = DataAccessException.class)
    public String defaultErrorHandler(HttpServletResponse response, DataAccessException e) throws Exception {
       response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
       //Json return
    }
}

Also try to catch this exception in CorsFilter and send 500 error, something like this

@ExceptionHandler(DataAccessException.class)
@ResponseBody
public String handleDataException(DataAccessException ex, HttpServletResponse response) {
    response.setStatus(HttpStatus.INTERNAL_SERVER_ERROR.value());
    //Json return
}

Here what you are looking for !!!

select LAST_INSERT_ID()

This is the best alternative of SCOPE_IDENTITY() function being used in SQL Server.

You also need to keep in mind that this will only work if Last_INSERT_ID() is fired following by your Insert query. That is the query returns the id inserted in the schema. You can not get specific table's last inserted id.

For more details please go through the link The equivalent of SQLServer function SCOPE_IDENTITY() in mySQL?

If all you need is a subject line (as in an alert message) simply do:

mailx -s "This is all she wrote" < /dev/null "myself@myaddress"

High level consumers are registered into Zookeeper, so you can fetch a list from ZK, similarly to the way kafka-topics.sh fetches the list of topics. I don't think there's a way to collect all consumers; any application sending in a few consume requests is actually a "consumer", and you cannot tell whether they are done already.

On the consumer side, there's a JMX metric exposed to monitor the lag. Also, there is Burrow for lag monitoring.

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:

sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:

axs.set_ylabel('mylabel',size=6)

you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.

def set_pubfig:
    sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.

Note: If you specify these numbers, specifying font_scale in sns.set_context is ignored for all specified font elements, even if you set it.

document.getElementsByClassName returns an array of elements. so may be you want to target a specific index of them: var comment = document.getElementsByClassName('button')[0]; should get you what you want.

Update #1:

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment() {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Update #2: (with removeEventListener incorporated as well)

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment(e) {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
  for (var i = 0; i < numComments; i++) {
    comments[i].removeEventListener('click', showComment, false);
  }
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Don't use systemPath. Contrary to what people have said here, you can put an external jar in a folder under your checked-out project directory and haven Maven find it like other dependencies. Here are two crucial steps:

1. Use "mvn install:install-file" with -DlocalRepositoryPath.
2. Configure a repository to point to that path in your POM.

It is fairly straightforward and you can find a step-by-step example here: http://randomizedsort.blogspot.com/2011/10/configuring-maven-to-use-local-library.html

Just to help anyone coming to this page. This is an alternate if you are flexible with using some other icon library.

James is correct that you cannot change the font weight however if you are looking for more modern look for icons then you might consider ionicons

It has both ios and android versions for icons.

DON'T use (.|[\r\n]) instead of . for multiline matching.

DO use [\s\S] instead of . for multiline matching

Also, avoid greediness where not needed by using *? or +? quantifier instead of * or +. This can have a huge performance impact.

See the benchmark I have made: http://jsperf.com/javascript-multiline-regexp-workarounds

Using [^]: fastest
Using [\s\S]: 0.83% slower
Using (.|\r|\n): 96% slower
Using (.|[\r\n]): 96% slower

NB: You can also use [^] but it is deprecated in the below comment.

Another difference to pay attention to is handling of undefined values:

mergeInto = { a: 1}
toMerge = {a : undefined, b:undefined}
lodash.extend({}, mergeInto, toMerge) // => {a: undefined, b:undefined}
lodash.merge({}, mergeInto, toMerge)  // => {a: 1, b:undefined}

So merge will not merge undefined values into defined values.

I looked over everyone's input above, which was very useful, and made a function which was appropriate for my own application. The function is really only evaluating that the user's input is not a "0", but it was good enough for my purpose. Hope this helps!

#include<stdio.h>

int iFunctErrorCheck(int iLowerBound, int iUpperBound){

int iUserInput=0;
while (iUserInput==0){
    scanf("%i", &iUserInput);
    if (iUserInput==0){
        printf("Please enter an integer (%i-%i).\n", iLowerBound, iUpperBound);
        getchar();
    }
    if ((iUserInput!=0) && (iUserInput<iLowerBound || iUserInput>iUpperBound)){
        printf("Please make a valid selection (%i-%i).\n", iLowerBound, iUpperBound);
        iUserInput=0;
    }
}
return iUserInput;
}

CASE AlarmEventTransactions.DeviceID should just be CASE.

You are mixing the 2 forms of the CASE expression.

Range("A:B,D:E,G:H").Select can help

Edit note: I just saw you have used different column sequence, I have updated my answer

Eloquent::insert is the proper solution but it wont update the timestamps, so you can do something like below

 $json_array=array_map(function ($a) { 
                        return array_merge($a,['created_at'=> 
                                            Carbon::now(),'updated_at'=> Carbon::now()]
                                           ); 
                                     }, $json_array); 
 Model::insert($json_array);

The idea is to add created_at and updated_at on whole array before doing insert

Try this :

$('#resetBtn').on('click', function(e){
    e.preventDefault();
    $("#myform")[0].reset.click();
}

I see this being possible using either some regex, or a few substr calls (assuming the input is always of that format, and doesn't change length etc.)

something like

$in = "+11234567890"; $output = substr($in,2,3)."-".substr($in,6,3)."-".substr($in,10,4);

should do it.

Update the pom.xml as -

<project>   
 ....
    <build>
      <resources>
        <resource>
          <directory>src/main/config</directory>
        </resource>
      </resources>
     ...
    </build>
...
</project>

In Rails 4, this is a better (DRYer) solution:

change_column_null :my_models, :date_column, false

To ensure no records exist with NULL values in that column, you can pass a fourth parameter, which is the default value to use for records with NULL values:

change_column_null :my_models, :date_column, false, Time.now

For the record, the spring.jpa.hibernate.ddl-auto property is Spring Data JPA specific and is their way to specify a value that will eventually be passed to Hibernate under the property it knows, hibernate.hbm2ddl.auto.

The values create, create-drop, validate, and update basically influence how the schema tool management will manipulate the database schema at startup.

For example, the update operation will query the JDBC driver's API to get the database metadata and then Hibernate compares the object model it creates based on reading your annotated classes or HBM XML mappings and will attempt to adjust the schema on-the-fly.

The update operation for example will attempt to add new columns, constraints, etc but will never remove a column or constraint that may have existed previously but no longer does as part of the object model from a prior run.

Typically in test case scenarios, you'll likely use create-drop so that you create your schema, your test case adds some mock data, you run your tests, and then during the test case cleanup, the schema objects are dropped, leaving an empty database.

In development, it's often common to see developers use update to automatically modify the schema to add new additions upon restart. But again understand, this does not remove a column or constraint that may exist from previous executions that is no longer necessary.

In production, it's often highly recommended you use none or simply don't specify this property. That is because it's common practice for DBAs to review migration scripts for database changes, particularly if your database is shared across multiple services and applications.

This worked for me, based on your code, generating a 93Mb png image with color noise and the desired dimensions:

import matplotlib.pyplot as plt
import numpy

w = 7195
h = 3841

im_np = numpy.random.rand(h, w)

fig = plt.figure(frameon=False)
fig.set_size_inches(w,h)
ax = plt.Axes(fig, [0., 0., 1., 1.])
ax.set_axis_off()
fig.add_axes(ax)
ax.imshow(im_np, aspect='normal')
fig.savefig('figure.png', dpi=1)

I am using the last PIP versions of the Python 2.7 libraries in Linux Mint 13.

Hope that helps!

Yor $.post has no data. You need to pass the form data. You can use serialize() to post the form data. Try this

$("#post-btn").click(function(){
    $.post("process.php", $('#reg-form').serialize() ,function(data){
        alert(data);
    });
});

I found the ioctl solution problematic on os x (which is POSIX compliant so should be similiar to linux). However getifaddress() will let you do the same thing easily, it works fine for me on os x 10.5 and should be the same below.

I've done a quick example below which will print all of the machine's IPv4 address, (you should also check the getifaddrs was successful ie returns 0).

I've updated it show IPv6 addresses too.

#include <stdio.h>      
#include <sys/types.h>
#include <ifaddrs.h>
#include <netinet/in.h> 
#include <string.h> 
#include <arpa/inet.h>

int main (int argc, const char * argv[]) {
    struct ifaddrs * ifAddrStruct=NULL;
    struct ifaddrs * ifa=NULL;
    void * tmpAddrPtr=NULL;

    getifaddrs(&ifAddrStruct);

    for (ifa = ifAddrStruct; ifa != NULL; ifa = ifa->ifa_next) {
        if (!ifa->ifa_addr) {
            continue;
        }
        if (ifa->ifa_addr->sa_family == AF_INET) { // check it is IP4
            // is a valid IP4 Address
            tmpAddrPtr=&((struct sockaddr_in *)ifa->ifa_addr)->sin_addr;
            char addressBuffer[INET_ADDRSTRLEN];
            inet_ntop(AF_INET, tmpAddrPtr, addressBuffer, INET_ADDRSTRLEN);
            printf("%s IP Address %s\n", ifa->ifa_name, addressBuffer); 
        } else if (ifa->ifa_addr->sa_family == AF_INET6) { // check it is IP6
            // is a valid IP6 Address
            tmpAddrPtr=&((struct sockaddr_in6 *)ifa->ifa_addr)->sin6_addr;
            char addressBuffer[INET6_ADDRSTRLEN];
            inet_ntop(AF_INET6, tmpAddrPtr, addressBuffer, INET6_ADDRSTRLEN);
            printf("%s IP Address %s\n", ifa->ifa_name, addressBuffer); 
        } 
    }
    if (ifAddrStruct!=NULL) freeifaddrs(ifAddrStruct);
    return 0;
}

I have found following solution to replace following code

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:3.2.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

It's work fine for me

Since most of the answers here are targeted towards iOS here's a solution for changing icon in Android.

For android:

Make changes in <project location>\platforms\android\ant-build\res and not <project location>\platforms\android\res

For some people making changes in the latter location may have worked, but having noticed Phonegap copying from \android\res into \android\ant-build\res, I decided to check in there and found a separate set of drawable folders containing the default phonegap icon.

Changing those finally worked.

Since I'm building and running locally and not using Adobe PhoneGap Build, changing icons in <project location>\www\res\icon\android didn't work either.

This is a 100% solution. I tried it myself.

myisamchk -r -v -f --sort_buffer_size=128M --key_buffer_size=128M /var/lib/mysql/databasename/tabloname

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??

if i am then please try this,

import csv

with open(r"C:\\test.csv", "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
    writer.writerow(["a","b"])

you have to set the delimiter = ","

If you need the highlighted tint which the OS provides by default when you tap and hold on a custom button for the selected state as well, use this UIButton subclass. Written in Swift 5:

import Foundation
import UIKit
class HighlightOnSelectCustomButton: UIButton {
    override var isHighlighted: Bool {
        didSet {
            if (self.isSelected != isHighlighted) {
                self.isHighlighted = self.isSelected
            }
        }
    }
}

why don't you use width: 100% and height: 100%.

1. It is recommend to use List to deal with small scale size.

2. If you have a huge number of numbers, NEVER use List and autoboxing,

   List< Integer> list

For every single int, a new Integer is auto created. You will find it getting slow when the size of the list increase. These Integers are unnecessary objects. In this case, to use a estimated size would be better,

int[] array = new int[ESTIMATED_SIZE];

This answer is for anyone encountering pdfs with images and needing to use OCR. I could not find a workable off-the-shelf solution; nothing that gave me the accuracy I needed.

Here are the steps I found to work.

1. Use pdfimages from https://poppler.freedesktop.org/ to turn the pages of the pdf into images.

2. Use Tesseract to detect rotation and ImageMagick mogrify to fix it.

3. Use OpenCV to find and extract tables.

4. Use OpenCV to find and extract each cell from the table.

5. Use OpenCV to crop and clean up each cell so that there is no noise that will confuse OCR software.

6. Use Tesseract to OCR each cell.

7. Combine the extracted text of each cell into the format you need.

I wrote a python package with modules that can help with those steps.

Repo: https://github.com/eihli/image-table-ocr

Docs & Source: https://eihli.github.io/image-table-ocr/pdf_table_extraction_and_ocr.html

Some of the steps don't require code, they take advantage of external tools like pdfimages and tesseract. I'll provide some brief examples for a couple of the steps that do require code.

2. Finding tables:

This link was a good reference while figuring out how to find tables. https://answers.opencv.org/question/63847/how-to-extract-tables-from-an-image/

import cv2

def find_tables(image):
    BLUR_KERNEL_SIZE = (17, 17)
    STD_DEV_X_DIRECTION = 0
    STD_DEV_Y_DIRECTION = 0
    blurred = cv2.GaussianBlur(image, BLUR_KERNEL_SIZE, STD_DEV_X_DIRECTION, STD_DEV_Y_DIRECTION)
    MAX_COLOR_VAL = 255
    BLOCK_SIZE = 15
    SUBTRACT_FROM_MEAN = -2

    img_bin = cv2.adaptiveThreshold(
        ~blurred,
        MAX_COLOR_VAL,
        cv2.ADAPTIVE_THRESH_MEAN_C,
        cv2.THRESH_BINARY,
        BLOCK_SIZE,
        SUBTRACT_FROM_MEAN,
    )
    vertical = horizontal = img_bin.copy()
    SCALE = 5
    image_width, image_height = horizontal.shape
    horizontal_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (int(image_width / SCALE), 1))
    horizontally_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, horizontal_kernel)
    vertical_kernel = cv2.getStructuringElement(cv2.MORPH_RECT, (1, int(image_height / SCALE)))
    vertically_opened = cv2.morphologyEx(img_bin, cv2.MORPH_OPEN, vertical_kernel)

    horizontally_dilated = cv2.dilate(horizontally_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (40, 1)))
    vertically_dilated = cv2.dilate(vertically_opened, cv2.getStructuringElement(cv2.MORPH_RECT, (1, 60)))

    mask = horizontally_dilated + vertically_dilated
    contours, hierarchy = cv2.findContours(
        mask, cv2.RETR_EXTERNAL, cv2.CHAIN_APPROX_SIMPLE,
    )

    MIN_TABLE_AREA = 1e5
    contours = [c for c in contours if cv2.contourArea(c) > MIN_TABLE_AREA]
    perimeter_lengths = [cv2.arcLength(c, True) for c in contours]
    epsilons = [0.1 * p for p in perimeter_lengths]
    approx_polys = [cv2.approxPolyDP(c, e, True) for c, e in zip(contours, epsilons)]
    bounding_rects = [cv2.boundingRect(a) for a in approx_polys]

    # The link where a lot of this code was borrowed from recommends an
    # additional step to check the number of "joints" inside this bounding rectangle.
    # A table should have a lot of intersections. We might have a rectangular image
    # here though which would only have 4 intersections, 1 at each corner.
    # Leaving that step as a future TODO if it is ever necessary.
    images = [image[y:y+h, x:x+w] for x, y, w, h in bounding_rects]
    return images

3. Extract cells from table.

This is very similar to 2, so I won't include all the code. The part I will reference will be in sorting the cells.

We want to identify the cells from left-to-right, top-to-bottom.

We’ll find the rectangle with the most top-left corner. Then we’ll find all of the rectangles that have a center that is within the top-y and bottom-y values of that top-left rectangle. Then we’ll sort those rectangles by the x value of their center. We’ll remove those rectangles from the list and repeat.

def cell_in_same_row(c1, c2):
    c1_center = c1[1] + c1[3] - c1[3] / 2
    c2_bottom = c2[1] + c2[3]
    c2_top = c2[1]
    return c2_top < c1_center < c2_bottom

orig_cells = [c for c in cells]
rows = []
while cells:
    first = cells[0]
    rest = cells[1:]
    cells_in_same_row = sorted(
        [
            c for c in rest
            if cell_in_same_row(c, first)
        ],
        key=lambda c: c[0]
    )

    row_cells = sorted([first] + cells_in_same_row, key=lambda c: c[0])
    rows.append(row_cells)
    cells = [
        c for c in rest
        if not cell_in_same_row(c, first)
    ]

# Sort rows by average height of their center.
def avg_height_of_center(row):
    centers = [y + h - h / 2 for x, y, w, h in row]
    return sum(centers) / len(centers)

rows.sort(key=avg_height_of_center)

One possible idea is to write separate constructor function

//Something is the structure we work with
type Something struct {
     Text string 
     DefaultText string 
} 
// NewSomething create new instance of Something
func NewSomething(text string) Something {
   something := Something{}
   something.Text = text
   something.DefaultText = "default text"
   return something
}

The use of -X [WHATEVER] merely changes the request's method string used in the HTTP request. This is easier to understand with two examples — one with -X [WHATEVER] and one without — and the associated HTTP request headers for each:

# curl -XPANTS -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.224.86.126) port 80 (#0)
> PANTS / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*

# curl -o nul -v http://neverssl.com/
* Connected to neverssl.com (13.33.50.167) port 80 (#0)
> GET / HTTP/1.1
> Host: neverssl.com
> User-Agent: curl/7.42.0
> Accept: */*

Here is the code to redirect to some other page with a timeout of 10 seconds.

<script>
    function Redirect()
    {
        window.location="http://www.adarshkr.com";
    }

    document.write("You will be redirected to a new page in 10 seconds.");
    setTimeout('Redirect()', 10000);
</script>

You can also do it like this, on click of a button using location.assign:

<input type="button" value="Load new document" onclick="newPage()">
<script>
    function newPage() {
        window.location.assign("http://www.adarshkr.com")
    }
</script>

I faced this problem while using AptanaStudio3 on windows7. This helped me:

git config --global credential.helper wincred

print_r($query->getBindings());

If that's right, then I think something like

import csv

with open("test.dat", "rb") as infile, open("test.csv", "wb") as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, quoting=False)
    for i, line in enumerate(reader):
        if i < 4: continue
        date = line[0].split()
        day = date[0].split('-')
        time = date[1].split(':')
        newline = day + time + line[1:]
        writer.writerow(newline)

would be a little simpler than the reps stuff.

z-index only works on absolute or relatively positioned elements. I would use an outer div set to position relative. Set the div on top to position absolute to remove it from the flow of the document.

Update: ICS emulator supports camera.

Another solution, if you find yourself casting the same object a lot and you don't want to litter your code with @SupressWarnings("unchecked"), would be to create a method with the annotation. This way you're centralizing the cast, and hopefully reducing the possibility for error.

@SuppressWarnings("unchecked")
public static List<String> getFooStrings(Map<String, List<String>> ctx) {
    return (List<String>) ctx.get("foos");
}

So there are few places where terminal looks for commands. This places are stored in your $PATH variable. Think of it as a global variable where terminal iterates over to look up for any command. This are usually binaries look how /bin folder is usually referenced.

/bin folder has lots of executable files inside it. Turns out this are command. This different folder locations are stored inside one Global variable i.e. $PATH separated by :

Now usually programs upon installation takes care of updating PATH & telling your terminal that hey i can be all commands inside my bin folder.

Turns out MySql doesn't do it upon install so we manually have to do it.

We do it by following command,

export PATH=$PATH:/usr/local/mysql/bin

If you break it down, export is self explanatory. Think of it as an assignment. So export a variable PATH with value old $PATH concat with new bin i.e. /usr/local/mysql/bin

This way after executing it all the commands inside /usr/local/mysql/bin are available to us.

There is a small catch here. Think of one terminal window as one instance of program and maybe something like $PATH is class variable ( maybe ). Note this is pure assumption. So upon close we lose the new assignment. And if we reopen terminal we won't have access to our command again because last when we exported, it was stored in primary memory which is volatile.

Now we need to have our mysql binaries exported every-time we use terminal. So we have to persist concat in our path.

You might be aware that our terminal using something called dotfiles to load configuration on terminal initialisation. I like to think of it's as sets of thing passed to constructer every-time a new instance of terminal is created ( Again an assumption but close to what it might be doing ). So yes by now you get the point what we are going todo.

.bash_profile is one of the primary known dotfile.

So in following command,

echo 'export PATH=$PATH:/usr/local/mysql/bin' >> ~/.bash_profile

What we are doing is saving result of echo i.e. output string to ~/.bash_profile

So now as we noted above every-time we open terminal or instance of terminal our dotfiles are loaded. So .bash_profile is loaded respectively and export that we appended above is run & thus a our global $PATH gets updated and we get all the commands inside /usr/local/mysql/bin.

P.s.

if you are not running first command export directly but just running second in order to persist it? Than for current running instance of terminal you have to,

source ~/.bash_profile

This tells our terminal to reload that particular file.

There's no built-in method for doing this in Python 2. If you need this, you need to write a prepend() method/function that operates on the OrderedDict internals with O(1) complexity.

For Python 3.2 and later, you should use the move_to_end method. The method accepts a last argument which indicates whether the element will be moved to the bottom (last=True) or the top (last=False) of the OrderedDict.

Finally, if you want a quick, dirty and slow solution, you can just create a new OrderedDict from scratch.

Details for the four different solutions:

Extend OrderedDict and add a new instance method

from collections import OrderedDict

class MyOrderedDict(OrderedDict):

    def prepend(self, key, value, dict_setitem=dict.__setitem__):

        root = self._OrderedDict__root
        first = root[1]

        if key in self:
            link = self._OrderedDict__map[key]
            link_prev, link_next, _ = link
            link_prev[1] = link_next
            link_next[0] = link_prev
            link[0] = root
            link[1] = first
            root[1] = first[0] = link
        else:
            root[1] = first[0] = self._OrderedDict__map[key] = [root, first, key]
            dict_setitem(self, key, value)

Demo:

>>> d = MyOrderedDict([('a', '1'), ('b', '2')])
>>> d
MyOrderedDict([('a', '1'), ('b', '2')])
>>> d.prepend('c', 100)
>>> d
MyOrderedDict([('c', 100), ('a', '1'), ('b', '2')])
>>> d.prepend('a', d['a'])
>>> d
MyOrderedDict([('a', '1'), ('c', 100), ('b', '2')])
>>> d.prepend('d', 200)
>>> d
MyOrderedDict([('d', 200), ('a', '1'), ('c', 100), ('b', '2')])

Standalone function that manipulates OrderedDict objects

This function does the same thing by accepting the dict object, key and value. I personally prefer the class:

from collections import OrderedDict

def ordered_dict_prepend(dct, key, value, dict_setitem=dict.__setitem__):
    root = dct._OrderedDict__root
    first = root[1]

    if key in dct:
        link = dct._OrderedDict__map[key]
        link_prev, link_next, _ = link
        link_prev[1] = link_next
        link_next[0] = link_prev
        link[0] = root
        link[1] = first
        root[1] = first[0] = link
    else:
        root[1] = first[0] = dct._OrderedDict__map[key] = [root, first, key]
        dict_setitem(dct, key, value)

Demo:

>>> d = OrderedDict([('a', '1'), ('b', '2')])
>>> ordered_dict_prepend(d, 'c', 100)
>>> d
OrderedDict([('c', 100), ('a', '1'), ('b', '2')])
>>> ordered_dict_prepend(d, 'a', d['a'])
>>> d
OrderedDict([('a', '1'), ('c', 100), ('b', '2')])
>>> ordered_dict_prepend(d, 'd', 500)
>>> d
OrderedDict([('d', 500), ('a', '1'), ('c', 100), ('b', '2')])

Use OrderedDict.move_to_end() (Python >= 3.2)

Python 3.2 introduced the OrderedDict.move_to_end() method. Using it, we can move an existing key to either end of the dictionary in O(1) time.

>>> d1 = OrderedDict([('a', '1'), ('b', '2')])
>>> d1.update({'c':'3'})
>>> d1.move_to_end('c', last=False)
>>> d1
OrderedDict([('c', '3'), ('a', '1'), ('b', '2')])

If we need to insert an element and move it to the top, all in one step, we can directly use it to create a prepend() wrapper (not presented here).

Create a new OrderedDict - slow!!!

If you don't want to do that and performance is not an issue then easiest way is to create a new dict:

from itertools import chain, ifilterfalse
from collections import OrderedDict


def unique_everseen(iterable, key=None):
    "List unique elements, preserving order. Remember all elements ever seen."
    # unique_everseen('AAAABBBCCDAABBB') --> A B C D
    # unique_everseen('ABBCcAD', str.lower) --> A B C D
    seen = set()
    seen_add = seen.add
    if key is None:
        for element in ifilterfalse(seen.__contains__, iterable):
            seen_add(element)
            yield element
    else:
        for element in iterable:
            k = key(element)
            if k not in seen:
                seen_add(k)
                yield element

d1 = OrderedDict([('a', '1'), ('b', '2'),('c', 4)])
d2 = OrderedDict([('c', 3), ('e', 5)])   #dict containing items to be added at the front
new_dic = OrderedDict((k, d2.get(k, d1.get(k))) for k in \
                                           unique_everseen(chain(d2, d1)))
print new_dic

output:

OrderedDict([('c', 3), ('e', 5), ('a', '1'), ('b', '2')])

employee first table. report second table. birth third table

Just an extra comment on something that is often overlooked. Sometimes not using a surrogate key has benefits in the child tables. Let's say we have a design that allows you to run multiple companies within the one database (maybe it's a hosted solution, or whatever).

Let's say we have these tables and columns:

Company:
  CompanyId   (primary key)

CostCenter:
  CompanyId   (primary key, foreign key to Company)
  CostCentre  (primary key)

CostElement
  CompanyId   (primary key, foreign key to Company)
  CostElement (primary key)

Invoice:
  InvoiceId    (primary key)
  CompanyId    (primary key, in foreign key to CostCentre, in foreign key to CostElement)
  CostCentre   (in foreign key to CostCentre)
  CostElement  (in foreign key to CostElement)

In case that last bit doesn't make sense, Invoice.CompanyId is part of two foreign keys, one to the CostCentre table and one to the CostElement table. The primary key is (InvoiceId, CompanyId).

In this model, it's not possible to screw-up and reference a CostElement from one company and a CostCentre from another company. If a surrogate key was used on the CostElement and CostCentre tables, it would be.

The fewer chances to screw up, the better.

You can use a Web Method and Ajax:

<script type="text/javascript">             //Default.aspx
   function DeleteKartItems() {     
         $.ajax({
         type: "POST",
         url: 'Default.aspx/DeleteItem',
         data: "",
         contentType: "application/json; charset=utf-8",
         dataType: "json",
         success: function (msg) {
             $("#divResult").html("success");
         },
         error: function (e) {
             $("#divResult").html("Something Wrong.");
         }
     });
   }
</script>

[WebMethod]                                 //Default.aspx.cs
public static void DeleteItem()
{
    //Your Logic
}

Make sure your .NET version 4.5 or greater

you can try this code:

                dataGridView1.BeginEdit(true);
                if (chk.Value == null || (int)chk.Value == 0)
                {
                    chk.Value = 1;
                }
                else
                {
                    chk.Value = 0;

Set a minimum width at the top most layout.

android:minWidth="300dp"

For example:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"
  xmlns:android="http://schemas.android.com/apk/res/android" android:minWidth="300dp">

<!-- Put remaining contents here -->

</LinearLayout>

Not on the freehackers list is gui2exe which can be used to build standalone Windows executables, Linux applications and Mac OS application bundles and plugins starting from Python scripts.

You have no public getters for your UpdateResult, for example :

public static class UploadResult {
    private String value;
    public UploadResult(final String value)
    {
        this.value = value;
    }

    public String getValue() {
       return this.value;
    }
}

I believe by default auto discovery is on and will try to discover your getters. You can disable it with @JsonAutoDetect(getterVisibility=Visibility.NONE), and in your example will result in [].

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class Regex1 {
    public static void main(String[]args) {
        Pattern p = Pattern.compile("\\d+");
        Matcher m = p.matcher("hello1234goodboy789very2345");
        while(m.find()) {
            System.out.println(m.group());
        }
    }
}

Output:

1234

Use the ? symbol (encoded as ⚲ or ⚲), and rotate it to achieve the desired effect:

<div style="-webkit-transform: rotate(45deg); 
               -moz-transform: rotate(45deg); 
                 -o-transform: rotate(45deg);
                    transform: rotate(45deg);">
    &#9906;
</div>

It rotates a symbol :)

I just cleaned up RHT's answer to eliminate some warnings and thought I would share. Eclipse did most of the work:

public List<HashMap<String,Object>> convertResultSetToList(ResultSet rs) throws SQLException {
    ResultSetMetaData md = rs.getMetaData();
    int columns = md.getColumnCount();
    List<HashMap<String,Object>> list = new ArrayList<HashMap<String,Object>>();

    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);
    }

    return list;
}

Service references deal with endpoints and bindings, which are completely configurable. They let you point your client proxy to a WCF via any transport protocol (HTTP, TCP, Shared Memory, etc)

They are designed to work with WCF.

If you use a WebProxy, you are pretty much binding yourself to using WCF over HTTP

No you would have to create your own solution. Like using the Observer design pattern or something.

If you have no control over the variable or who is using it, I'm afraid you're doomed. EDIT: Or use Skilldrick's solution!

To reset your keyring.

1. Go into your home folder.

2. Press ctrl & h to show your hidden folders.

3. Now look in your .gnome2/keyrings directory.

4. Find the default.keyring file.

5. Move that file to a different folder.

6. Once done, reboot your computer.

One way is to use window.print() function. Which does not require any library

Pros

1.No external library require.

2.We can print only selected parts of body also.

3.No css conflicts and js issues.

4.Core html/js functionality

---Simply add below code

CSS to

@media print {
        body * {
            visibility: hidden; // part to hide at the time of print
            -webkit-print-color-adjust: exact !important; // not necessary use         
               if colors not visible
        }

        #printBtn {
            visibility: hidden !important; // To hide 
        }

        #page-wrapper * {
            visibility: visible; // Print only required part
            text-align: left;
            -webkit-print-color-adjust: exact !important;
        }
    }

JS code - Call bewlow function on btn click

$scope.printWindow = function () {
  window.print()
}

Note: Use !important in every css object

Example -

.legend  {
  background: #9DD2E2 !important;
}

You can use getFragmentManager().popBackStack() in basic Fragment to go back.

After upgrading to macOS v10.15 (Catalina), and upgrading all my vEnv modules, pip3 stopped working (gave error: "TypeError: 'module' object is not callable").

I found question 58386953 which led to here and solution.

1. Exit from the vEnv (I started a fresh shell)
2. sudo python3 -m pip uninstall pip (this is necessary, but it did not fix problem, because it removed the base Python pip, but it didn't touch my vEnv pip)
3. sudo easy_install pip (reinstalling pip in base Python, not in vEnv)
4. cd to your vEnv/bin and type "source activate" to get into vEnv
5. rm pip pip3 pip3.6 (it seems to be the only way to get rid of the bogus pip's in vEnv)
6. Now pip is gone from vEnv, and we can use the one in the base Python (I wasn't able to successfully install pip into vEnv after deleting)

connect your server from mysqlworkbench and run this command-> ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword';

This adds to rm8x's answer.

Download and install the NuGet command line tool.

• From Chocolatey → https://chocolatey.org/packages/NuGet.CommandLine
• from NuGet.org → https://www.nuget.org/

List all of our locals:

$ nuget locals all -list
http-cache: C:\Users\MyUser\AppData\Local\NuGet\v3-cache
packages-cache: C:\Users\MyUser\AppData\Local\NuGet\Cache
global-packages: C:\Users\MyUser\.nuget\packages\

We can now delete these manually or as rm8x suggests, use nuget locals all -clear.

Today. I have same problem... my solution:

1) check inode: df -i I saw:

root@vm22433:/etc/mysql# df -i
Filesystem Inodes IUsed IFree IUse% Mounted on
udev 124696 304 124392 1% /dev
tmpfs 127514 452 127062 1% /run
/dev/vda1 1969920 1969920 0 100% /
tmpfs 127514 1 127513 1% /dev/shm
tmpfs 127514 3 127511 1% /run/lock
tmpfs 127514 15 127499 1% /sys/fs/cgroup
tmpfs 127514 12 127502 1% /run/user/1002

2) I began to look what folders use the maximum number of inods:

 for i in /*; do echo $i; find $i |wc -l; done

soon I found in /home/tomnolane/tmp folder, which contained a huge number of files.

3) I removed /home/tomnolane/tmp folder PROFIT.

4) checked:

Filesystem      Inodes  IUsed   IFree IUse% Mounted on
udev            124696    304  124392    1% /dev
tmpfs           127514    454  127060    1% /run
/dev/vda1      1969920 450857 1519063   23% /
tmpfs           127514      1  127513    1% /dev/shm
tmpfs           127514      3  127511    1% /run/lock
tmpfs           127514     15  127499    1% /sys/fs/cgroup
tmpfs           127514     12  127502    1% /run/user/1002

it's ok.

5) restart mysql service - it's ok!!!!

This error might also occur due to proxy settings, once check that your proxy allow the access to npm commands.

It worked for me quite well.

NOTE: See @SDP's answer for a clean, built-in solution

I fixed it as follows:

make sure you include application.js before the other app dependent js files get included by changing the include order as follows:

// in application.js - make sure `require_self` comes before `require_tree .`
//= require_self
//= require_tree .

Define a global function that handles the binding in application.js

// application.js
window.onLoad = function(callback) {
  // binds ready event and turbolink page:load event
  $(document).ready(callback);
  $(document).on('page:load',callback);
};

Now you can bind stuff like:

// in coffee script:
onLoad ->
  $('a.clickable').click => 
    alert('link clicked!');

// equivalent in javascript:
onLoad(function() {
  $('a.clickable').click(function() {
    alert('link clicked');
});

Try to implement dynamic data structure such as a linked list

Let me address your question about "modes." AES256 is a kind of block cipher. It takes as input a 32-byte key and a 16-byte string, called the block and outputs a block. We use AES in a mode of operation in order to encrypt. The solutions above suggest using CBC, which is one example. Another is called CTR, and it's somewhat easier to use:

from Crypto.Cipher import AES
from Crypto.Util import Counter
from Crypto import Random

# AES supports multiple key sizes: 16 (AES128), 24 (AES192), or 32 (AES256).
key_bytes = 32

# Takes as input a 32-byte key and an arbitrary-length plaintext and returns a
# pair (iv, ciphtertext). "iv" stands for initialization vector.
def encrypt(key, plaintext):
    assert len(key) == key_bytes

    # Choose a random, 16-byte IV.
    iv = Random.new().read(AES.block_size)

    # Convert the IV to a Python integer.
    iv_int = int(binascii.hexlify(iv), 16) 

    # Create a new Counter object with IV = iv_int.
    ctr = Counter.new(AES.block_size * 8, initial_value=iv_int)

    # Create AES-CTR cipher.
    aes = AES.new(key, AES.MODE_CTR, counter=ctr)

    # Encrypt and return IV and ciphertext.
    ciphertext = aes.encrypt(plaintext)
    return (iv, ciphertext)

# Takes as input a 32-byte key, a 16-byte IV, and a ciphertext, and outputs the
# corresponding plaintext.
def decrypt(key, iv, ciphertext):
    assert len(key) == key_bytes

    # Initialize counter for decryption. iv should be the same as the output of
    # encrypt().
    iv_int = int(iv.encode('hex'), 16) 
    ctr = Counter.new(AES.block_size * 8, initial_value=iv_int)

    # Create AES-CTR cipher.
    aes = AES.new(key, AES.MODE_CTR, counter=ctr)

    # Decrypt and return the plaintext.
    plaintext = aes.decrypt(ciphertext)
    return plaintext

(iv, ciphertext) = encrypt(key, 'hella')
print decrypt(key, iv, ciphertext)

This is often referred to as AES-CTR. I would advise caution in using AES-CBC with PyCrypto. The reason is that it requires you to specify the padding scheme, as exemplified by the other solutions given. In general, if you're not very careful about the padding, there are attacks that completely break encryption!

Now, it's important to note that the key must be a random, 32-byte string; a password does not suffice. Normally, the key is generated like so:

# Nominal way to generate a fresh key. This calls the system's random number
# generator (RNG).
key1 = Random.new().read(key_bytes)

A key may be derived from a password, too:

# It's also possible to derive a key from a password, but it's important that
# the password have high entropy, meaning difficult to predict.
password = "This is a rather weak password."

# For added # security, we add a "salt", which increases the entropy.
#
# In this example, we use the same RNG to produce the salt that we used to
# produce key1.
salt_bytes = 8 
salt = Random.new().read(salt_bytes)

# Stands for "Password-based key derivation function 2"
key2 = PBKDF2(password, salt, key_bytes)

Some solutions above suggest using SHA256 for deriving the key, but this is generally considered bad cryptographic practice. Check out wikipedia for more on modes of operation.

In my case, I had created a run configuration and whenever I tried to run it, the error would be displayed. After searching on some websites, I edited the run configuration and under JRE tab, selected the runtime JRE as 'workspace default JRE' which I had already configured to point to my local Java JDK installation (ex. C:\Program Files (x86)\Java\jdk1.8.0_51). This solved my issue. Maybe it helps someone out there.

Here is an example of what I would do. I hope it's what you're looking for.

char_array = c("foo_bar","bar_foo","apple","beer")
a = data.frame("data"=char_array,"data2"=1:4)
a$data = substr(a$data,1,nchar(a$data)-3)

a should now contain:

  data data2
1 foo_ 1
2 bar_ 2
3   ap 3
4    b 4

If you use <img> tags, then webkit based browsers won't display embedded bitmapped images.

For any kind of advanced SVG use, including the SVG inline offers by far the most flexibility.

Internet Explorer and Edge will resize the SVG correctly, but you must specify both the height and width.

You can add onclick, onmouseover, etc. inside the svg, to any shape in the SVG: onmouseover="top.myfunction(evt);"

You can also use web fonts in the SVG by including them in your regular style sheet.

Note: if you are exporting SVG's from Illustrator, the web font names will be wrong. You can correct this in your CSS and avoid messing around in the SVG. For example, Illustrator gives the wrong name to Arial, and you can fix it like this:

@font-face {    
    font-family: 'ArialMT';    
    src:    
        local('Arial'),    
        local('Arial MT'),    
        local('Arial Regular');    
    font-weight: normal;    
    font-style: normal;    
}

All this works on any browser released since 2013.

For an example, see ozake.com. The whole site is made of SVG's except for the contact form.

Warning: Web fonts are imprecisely resized in Safari — and if you have lots of transitions from plain text to bold or italic, there may be a small amount of extra or missing space at the transition points. See my answer at this question for more information.

I have faced the same problem a week ago. The problem is with the time zone setting. Specify in other formats like mm/dd/yyyy (usually works).

Specifying the date as 30/12/2013 resulted in the error for me. However, specifying it as mm/dd/yyyy format worked.

If you need to convert your input the you can try looking into the CONVERT method. Syntax is

CONVERT(VARCHAR,@your_date_Value,103)

CONVERT(VARCHAR, '12/30/2013', 103)

The finishing 103 is the datetime format.

Refer this link for conversion formats and further reading. https://www.w3schools.com/sql/func_sqlserver_convert.asp

In XCode 6.3.1, if you use a NSTextField you will not see the checkbox for secure.

Instead of using NSTextField use NSSecureTextField

https://developer.apple.com/library/mac/documentation/Cocoa/Reference/ApplicationKit/Classes/NSSecureTextField_Class/index.html

I'm guessing this is a Swift/Objective-C change since there is now a class for secure text fields. In the above link it says Available in OS X v10.0 and later. If you know more about when/why/what versions of Swift/Objective-C, XCode, or OS X this

readline is specifically designed to work with terminal (that is process.stdin.isTTY === true). There are a lot of modules which provide split functionality for generic streams, like split. It makes things super-easy:

process.stdin.pipe(require('split')()).on('data', processLine)

function processLine (line) {
  console.log(line + '!')
}

While you do the following, technically speaking:

<button ng-click="doSomething($event)"></button>

// In controller:
$scope.doSomething = function($event) {
  //reference to the button that triggered the function:
  $event.target
};

This is probably something you don't want to do as AngularJS philosophy is to focus on model manipulation and let AngularJS do the rendering (based on hints from the declarative UI). Manipulating DOM elements and attributes from a controller is a big no-no in AngularJS world.

Explanation of the different parts:

• Content - The content of the box, where text and images appear

• Padding - Clears an area around the content. The padding is transparent

• Border - A border that goes around the padding and content

• Margin - Clears an area outside the border. The margin is transparent

Give unique class and different id for file input

           $("#tab-content").on('change',class,function()
               {

If you're in local machine then use this command

/usr/local/mysql/bin/mysqldump -h127.0.0.1 --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;

For remote machine, use below one

/usr/local/mysql/bin/mysqldump -h [remoteip] --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;

Tested with below sample snippet, tried with MapUtils, and Java8 Stream feature. It worked with both cases.

public static void main(String[] args) {
    Map<String, String> test = new HashMap<String, String>();
    test.put("a", "1");
    test.put("d", "1");
    test.put("b", "2");
    test.put("c", "3");
    test.put("d", "4");
    test.put("d", "41");

    System.out.println(test);

    Map<String, String> test1 = MapUtils.invertMap(test);

    System.out.println(test1);

    Map<String, String> mapInversed = 
            test.entrySet()
               .stream()
               .collect(Collectors.toMap(Map.Entry::getValue, Map.Entry::getKey));

    System.out.println(mapInversed);
}

Output:
{a=1, b=2, c=3, d=41}
{1=a, 2=b, 3=c, 41=d}
{1=a, 2=b, 3=c, 41=d}

You will have to submit this data to the server somehow. I'm assuming that you don't want to do a full page reload every time a user clicks a link, so you'll have to user XHR (AJAX). If you are not using jQuery (or some other JS library) you can read this tutorial on how to do the XHR request "by hand".

From the official documentation:

It is also convenient to have a ~/.pgpass file to avoid regularly having to type in passwords. See Section 30.13 for more information.

...

This file should contain lines of the following format:

hostname:port:database:username:password

The password field from the first line that matches the current connection parameters will be used.

@klode's answer is right.

However, you are supposed to set another response header to make your header accessible to others.

Example:

First, you add 'page-size' in response header

response.set('page-size', 20);

Then, all you need to do is expose your header

response.set('Access-Control-Expose-Headers', 'page-size')

For me, it turns out that there was an iOS system update pending asking to restart the computer. Restart and let the update finish solved my problem.

For enter event handling you can use

1. @keyup.enter or
2. @keyup.13

13 is the keycode of enter. For @ key event, the keycode is 50. So you can use @keyup.50.

For example:

<input @keyup.50="atPress()" />

Your error is caused by these:

Dim oTable As Table, oRow As Row,

These types, Table and Row are not variable types native to Excel. You can resolve this in one of two ways:

1. Include a reference to the Microsoft Word object model. Do this from Tools | References, then add reference to MS Word. While not strictly necessary, you may like to fully qualify the objects like Dim oTable as Word.Table, oRow as Word.Row. This is called early-binding.
2. Alternatively, to use late-binding method, you must declare the objects as generic Object type: Dim oTable as Object, oRow as Object. With this method, you do not need to add the reference to Word, but you also lose the intellisense assistance in the VBE.

I have not tested your code but I suspect ActiveDocument won't work in Excel with method #2, unless you properly scope it to an instance of a Word.Application object. I don't see that anywhere in the code you have provided. An example would be like:

Sub DeleteEmptyRows()
Dim wdApp as Object
Dim oTable As Object, As Object, _
TextInRow As Boolean, i As Long

Set wdApp = GetObject(,"Word.Application")

Application.ScreenUpdating = False

For Each oTable In wdApp.ActiveDocument.Tables

Scripts are loaded in the order you have defined them in the HTML.

Therefore if you first load:

<script type="text/javascript" src="./javascript.js"></script>

without loading jQuery first, then $ is not defined.

You need to first load jQuery so that you can use it.

I would also recommend placing your scripts at the bottom of your HTML for performance reasons.

Install and ensure mysqld us running..

Go into database and setup root user:

sudo mysql -u root
SELECT User,Host FROM mysql.user;
DROP USER 'root'@'localhost';
CREATE USER 'root'@'%' IDENTIFIED BY 'obamathelongleggedmacdaddy';
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
FLUSH PRIVILEGES;
exit;

Edit mysqld permissions and restart:

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

# edit the line to be this:
bind-address=0.0.0.0

sudo systemctl stop mysql
sudo systemctl start mysql

From another machine, test.. Obvs port (3306) on mysqld machine must allow connection from test machine.

mysql -u root -p -h 123.456.789.666

All the additional "security" of MySql doesn't help security at all, it just complicates and obfuscates, it is now actually easier to screw it up than in the old days, where you just used a really long password.

Just try this:

<button type="button">Click Me</button>
<p></p>
<script type="text/javascript">
    $(document).ready(function(){
        $("button").click(function(){

            $.ajax({
                type: 'POST',
                url: 'script.php',
                success: function(data) {
                    alert(data);
                    $("p").text(data);

                }
            });
   });
});
</script>

In script.php

<?php 
  echo "You win";
 ?>

Suppose if the list is a collection of objects like given below:

obj =  [
        {

            "subjectId" : "577a54c09c57916109142248", 
            "evaluableMaterialCount" : 0, 
            "subjectName" : "ASP.net"

        }, 
        {

            "subjectId" : "56645cd63c43a07b61c2c650", 
            "subjectName" : ".NET",         
        }, 
        {

            "subjectId" : "5656a2ec3c43a07b61c2bd83", 
            "subjectName" : "Python",

        }, 
        {

            "subjectId" : "5662add93c43a07b61c2c58c", 
            "subjectName" : "HTML"
        }
    ]

You can use the following method to find the index. Suppose the subjectId is 5662add93c43a07b61c2c58c then to get the index of the object in the list,

There are some good resources for ramping up on crypto. Here's one:

• http://research.microsoft.com/en-us/groups/crypto/firstcrypto.aspx

From that page:

In the most commonly used public-key cryptography system, invented by Ron Rivest, Adi Shamir, and Len Adleman in 1977, both the public and the private keys are derived from a pair of large prime numbers according to a relatively simple mathematical formula. In theory, it might be possible to derive the private key from the public key by working the formula backwards. But only the product of the large prime numbers is public, and factoring numbers of that size into primes is so hard that even the most powerful supercomputers in the world cant break an ordinary public key.

Bruce Schneier's book Applied Cryptography is another. I highly recommend that book; it's fun reading.

Cookies are stored in browser as a text file format.It stores limited amount of data, up to 4kb[4096bytes].A single Cookie can not hold multiple values but yes we can have more than one cookie.

Cookies are easily accessible so they are less secure. The setcookie() function must appear BEFORE the tag.

Sessions are stored in server side.There is no such storage limit on session .Sessions can hold multiple variables.Since they are not easily accessible hence are more secure than cookies.

you can also change you can also change MinimumSize

No, you cannot set them all in a single statement.
At the general case, you need at least three properties:

border-color: red green white blue;
border-style: solid dashed dotted solid;
border-width: 1px 2px 3px 4px;

However, that would be quite messy. It would be more readable and maintainable with four:

border-top:    1px solid  #ff0;
border-right:  2px dashed #f0F;
border-bottom: 3px dotted #f00;
border-left:   5px solid  #09f;

Not sure what your desired output is, but if you're using list comprehension, the order follows the order of nested loops, which you have backwards. So I got the what I think you want with:

[float(y) for x in l for y in x]

The principle is: use the same order you'd use in writing it out as nested for loops.

This is my version referring @Virako 's code snippet

def adjust_column_width_from_col(ws, min_row, min_col, max_col):

        column_widths = []

        for i, col in \
                enumerate(
                    ws.iter_cols(min_col=min_col, max_col=max_col, min_row=min_row)
                ):

            for cell in col:
                value = cell.value
                if value is not None:

                    if isinstance(value, str) is False:
                        value = str(value)

                    try:
                        column_widths[i] = max(column_widths[i], len(value))
                    except IndexError:
                        column_widths.append(len(value))

        for i, width in enumerate(column_widths):

            col_name = get_column_letter(min_col + i)
            value = column_widths[i] + 2
            ws.column_dimensions[col_name].width = value

And how to use is as follows,

adjust_column_width_from_col(ws, 1,1, ws.max_column)

actually a much easier way to get a readable array of what you (probably) want to see, is instead of using

dd($users); 

or

dd(User::all());

use this

dd($users->toArray());

or

 dd(User::all()->toArray());

which is a lot nicer to debug with.

EDIT - additional, this also works nicely in your views / templates so if you pass the get all users to your template, you can then dump it into your blade template

{{ dd($users->toArray()) }}

There are some great examples in here, but I couldn't get this to work in all cases when also dealing with multiple lines of text (text wrapping). To finally get it to work I combined a couple of the techniques:

1. I used Jesse Crossen example above. However, I fixed a text height issue and I added the ability to specify a horizontal text margin. The margin is useful when allowing text to wrap so it doesn't hit the edge of the button:

   // the space between the image and text
   CGFloat spacing = 10.0;
   float   textMargin = 6;
   
   // get the size of the elements here for readability
   CGSize  imageSize   = picImage.size;
   CGSize  titleSize   = button.titleLabel.frame.size;
   CGFloat totalHeight = (imageSize.height + titleSize.height + spacing);      // get the height they will take up as a unit
   
   // lower the text and push it left to center it
   button.titleEdgeInsets = UIEdgeInsetsMake( 0.0, -imageSize.width +textMargin, - (totalHeight - titleSize.height), +textMargin );   // top, left, bottom, right
   
   // the text width might have changed (in case it was shortened before due to 
   // lack of space and isn't anymore now), so we get the frame size again
   titleSize = button.titleLabel.bounds.size;
   
   button.imageEdgeInsets = UIEdgeInsetsMake(-(titleSize.height + spacing), 0.0, 0.0, -titleSize.width );     // top, left, bottom, right        
   

2. Make sure you setup the text label to wrap

   button.titleLabel.numberOfLines = 2; 
   button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
   button.titleLabel.textAlignment = UITextAlignmentCenter;
   

3. This will mostly work now. However, I had some buttons that wouldn't render their image correctly. The image was either shifted to far to the right or left (it wasn't centered). So I used an UIButton layout override technique to force the imageView to be centered.

   @interface CategoryButton : UIButton
   @end
   
   @implementation CategoryButton
   
   - (void)layoutSubviews
   {
       // Allow default layout, then center imageView
       [super layoutSubviews];
   
       UIImageView *imageView = [self imageView];
       CGRect imageFrame = imageView.frame;
       imageFrame.origin.x = (int)((self.frame.size.width - imageFrame.size.width)/ 2);
       imageView.frame = imageFrame;
   }
   @end
   

I am about 8 years late, well...anyways, I don't really know what then() does but maybe MDN might have an answer. Actually, I might actually understand it a little more.

This will show you all the information (hopefully), you need. Unless someone already posted this link. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/then

The format is promise.prototype.then() The promise and prototype are kind of like variables but not like variables in javascript, I mean like other things go there like navigator.getBattery().then() where this one actually exists but is barely used on the web, this one shows statuses about the battery of the device, more information and more on MDN if you are curious.

In Linux, there is different escape sequences for control terminal. For example, there is special escape sequence for erase whole line: \33[2K and for move cursor to previous line: \33[1A. So all you need is to print this every time you need to refresh the line. Here is the code which prints Line 1 (second variant):

System.out.println("Line 1 (first variant)");
System.out.print("\33[1A\33[2K");
System.out.println("Line 1 (second variant)");

There are codes for cursor navigation, clearing screen and so on.

I think there are some libraries which helps with it (ncurses?).

The difference is that the value of a static readonly field is set at run time, so it can have a different value for different executions of the program. However, the value of a const field is set to a compile time constant.

Remember: For reference types, in both cases (static and instance), the readonly modifier only prevents you from assigning a new reference to the field. It specifically does not make immutable the object pointed to by the reference.

For details, please refer to C# Frequently Asked Questions on this topic: http://blogs.msdn.com/csharpfaq/archive/2004/12/03/274791.aspx

Great question, and it's odd that the Swing toolkit doesn't include this functionality natively for JTextFields. But, here's a great answer from my Udemy.com course "Learn Java Like a Kid":

txtGuess = new JTextField();
txtGuess.addKeyListener(new KeyAdapter() {
    public void keyTyped(KeyEvent e) { 
        if (txtGuess.getText().length() >= 3 ) // limit textfield to 3 characters
            e.consume(); 
    }  
});

This limits the number of characters in a guessing game text field to 3 characters, by overriding the keyTyped event and checking to see if the textfield already has 3 characters - if so, you're "consuming" the key event (e) so that it doesn't get processed like normal.

The solution that for me works is:

For Each xCell In Selection

  xCell.Value = CDec(xCell.Value)

Next xCell 

This is how I use it across domains...

• Use an iframe from your parent domain - say parent.com
• Then on each child.com domain, just do a postMessage to your parent.com iframe
• All you need to do is setup a protocol of how to interpret your postMessage messages to talk to the parent.com iframe.

I hope it helps :)

Since C++11 it can be done inside a class with constexpr.

class stat {
    public:
        // init inside class
        static constexpr double inlineStaticVar = 22;
};

The variable can now be accessed with:

stat::inlineStaticVar

SELECT table_name  from all_tables where owner = 'YOURSCHEMA';

Just create another class and add along with the bootstrap container class. You can also use container-fluid though.

<div class="container full-width">
    <div class="row">
        ....
    </div>
</div>

The CSS part is pretty simple

* {
    margin: 0;
    padding: 0;
}
.full-width {
    width: 100%;
    min-width: 100%;
    max-width: 100%;
}

Hope this helps, Thanks!

Just incase if anyone is looking for how to do it in typescript here is the solution

   @Watch('$route', { immediate: true, deep: true })
   onUrlChange(newVal: Route) {
      // Some action
    }

And yes as mentioned by @Coops below, please do not forget to include

import { Watch } from 'vue-property-decorator';

Edit: Alcalyn made a very good point of using Route type instead of using any

import { Watch } from 'vue-property-decorator';    
import { Route } from 'vue-router';

I think the first thing to do before all the other solutions is:

1. Check whether your device is online or not?

2. If you are running the application on the real device then the device should be on the same network where the development server is running.

Can you show code which you use for setting date object? Anyway< you can use this code for intialisation of date:

new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").parse("2011-01-01 00:00:00")

You are opening an asynchronous connection, yet you have written your code as if it was synchronous. The reqListener callback function will not execute synchronously with your code (that is, before React.createClass), but only after your entire snippet has run, and the response has been received from your remote location.

Unless you are on a zero-latency quantum-entanglement connection, this is well after all your statements have run. For example, to log the received data, you would:

function reqListener(e) {
    data = JSON.parse(this.responseText);
    console.log(data);
}

I'm not seeing the use of data in the React component, so I can only suggest this theoretically: why not update your component in the callback?

Class selectors are prefixed with a dot. Your .find() is missing that so jQuery thinks you're looking for <myClass> elements.

var myVar = $("#start").find('.myClass').val();

I fixed the problem by reinstalling the package with:

pip install --force-reinstall google-api-python-client

I had the same problem and found that there was no package.json in my project (but only the package-lock.json). I then

1. restored the package.json from source control
2. uninstalled the global and local angular-cli versions (like the instruction says)
3. followed the standard upgrade procedure

..and all worked out fine. Took a while to figure it out, but that did it for me.

I asked in the discussion:

does ssh -T [email protected] ouput the same username (in Hi [My Username]!) as in the one used for the ssh url of your repo ([email protected]:username/repo.git)?

Sorry It not showing same name

That means somehow the credentials have changed.

One solution would be to at least copy %HOME%\.ssh\id_rsa.pub in the SSH keys section of the right GitHub account

The OP adds:

I am working on private repo. So In [email protected]:username/repo.git,

I replied:

If you were able to clone/push to that repo whose username is not your own GitHub account, that must be because you had your previous public ssh key added as a contributor to that repo by the repo's owner.

What next is to ask that same repo owner to add your current public ssh key %HOME%\.ssh\id_rsa.pub to the repo contributor list.
So check with the owner that you (meaning your public ssh key) are declared as a contributor.

git diff path/file.css | grep -E "^\+" | grep -v '+++ b/' | cut -c 2-

• grep -E "^\+" is from previous accepted answer, it is incomplete because leaves non-source stuff
• grep -v '+++ b' removes non-source line with file name of later version
• cut -c 2- removes column of + signs, also may use sed 's/^\+//'

comm or sdiff were not an option because of git.

If you have one project referencing another project (such as a 'Windows Application' type referencing a 'Class Library') and both have the same Assembly name, you'll get this error. You can either strongly name the referenced project or (even better) rename the assembly of the referencing project (under the 'Application' tab of project properties in VS).

Here are a few ways of removing a single ' from a string in python.

• str.replace

  replace is usually used to return a string with all the instances of the substring replaced.

  "A single ' char".replace("'","")
  

• str.translate

  In Python 2

  To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.

  "A single ' char".translate(None,"'")
  

  In Python 3

  You will have to use str.maketrans

  "A single ' char".translate(str.maketrans({"'":None}))
  

• re.sub

  Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.

  re.sub("'","","A single ' char")
  

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

• Using list comprehension

  ''.join([c for c in string if c != "'"])
  

• Using generator Expression

  ''.join(c for c in string if c != "'")
  

Another final method can be used also (Again not recommended - works only if there is only one occurrence )

• Using list call along with remove and join.

  x = list(string)
  x.remove("'")
  ''.join(x)
  

in java1.7+ You can use this code to get file`s create time !

private static LocalDateTime getCreateTime(File file) throws IOException {
        Path path = Paths.get(file.getPath());
        BasicFileAttributeView basicfile = Files.getFileAttributeView(path, BasicFileAttributeView.class, LinkOption.NOFOLLOW_LINKS);
        BasicFileAttributes attr = basicfile.readAttributes();
        long date = attr.creationTime().toMillis();
        Instant instant = Instant.ofEpochMilli(date);
        return LocalDateTime.ofInstant(instant, ZoneId.systemDefault());
    }

Here I got the error: Failed to execute 'atob' on 'Window': The string to be decoded is not correctly encoded.

Because you didn't pass a base64-encoded string. Look at your functions: both download and dataURItoBlob do expect a data URI for some reason; you however are passing a plain html markup string to download in your example.

Not only is HTML invalid as base64, you are calling .split(',')[1] on it which will yield undefined - and "undefined" is not a valid base64-encoded string either.

I don't know, but I read that I need to encode my string to base64

That doesn't make much sense to me. You want to encode it somehow, only to decode it then?

What should I call and how?

Change the interface of your download function back to where it received the filename and text arguments.

Notice that the BlobBuilder does not only support appending whole strings (so you don't need to create those ArrayBuffer things), but also is deprecated in favor of the Blob constructor.

Can I put a name on my saved file?

Yes. Don't use the Blob constructor, but the File constructor.

function download(filename, text) {
    try {
        var file = new File([text], filename, {type:"text/plain"});
    } catch(e) {
        // when File constructor is not supported
        file = new Blob([text], {type:"text/plain"});
    }
    var url  = window.URL.createObjectURL(file);
    …
}

download('test.html', "<html>" + document.documentElement.innerHTML + "</html>");

See JavaScript blob filename without link on what to do with that object url, just setting the current location to it doesn't work.

INSERT INTO atable (x,y,z) VALUES ( NULL,NULL,NULL)

Another approach to remove the first line from file, using multiple assignment technique. Refer Link

 $firstLine, $restOfDocument = Get-Content -Path $filename 
 $modifiedContent = $restOfDocument 
 $modifiedContent | Out-String | Set-Content $filename

it looks like datetime.now() is being evaluated when the model is defined, and not each time you add a record.

Django has a feature to accomplish what you are trying to do already:

date = models.DateTimeField(auto_now_add=True, blank=True)

or

date = models.DateTimeField(default=datetime.now, blank=True)

The difference between the second example and what you currently have is the lack of parentheses. By passing datetime.now without the parentheses, you are passing the actual function, which will be called each time a record is added. If you pass it datetime.now(), then you are just evaluating the function and passing it the return value.

More information is available at Django's model field reference

Simlpy close and re-open the PR if you do not have the write access.

For API 21+, Use Clip Views

Rounded outline clipping was added to the View class in API 21. See this training doc or this reference for more info.

This in-built feature makes rounded corners very easy to implement. It works on any view or layout and supports proper clipping.

Here's What To Do:

• Create a rounded shape drawable and set it as your view's background: android:background="@drawable/round_outline"
• Clip to outline in code: setClipToOutline(true)

The documentation used to say that you can set android:clipToOutline="true" the XML, but this bug is now finally resolved and the documentation now correctly states that you can only do this in code.

What It Looks Like:

Special Note About ImageViews

setClipToOutline() only works when the View's background is set to a shape drawable. If this background shape exists, View treats the background's outline as the borders for clipping and shadowing purposes.

This means that if you want to round the corners on an ImageView with setClipToOutline(), your image must come from android:src instead of android:background (since background is used for the rounded shape). If you MUST use background to set your image instead of src, you can use this nested views workaround:

• Create an outer layout with its background set to your shape drawable
• Wrap that layout around your ImageView (with no padding)
• The ImageView (including anything else in the layout) will now be clipped to the outer layout's rounded shape.

If no table with such name exists, DROP fails with error while DROP IF EXISTS just does nothing.

This is useful if you create/modifi your database with a script; this way you do not have to ensure manually that previous versions of the table are deleted. You just do a DROP IF EXISTS and forget about it.

Of course, your current DB engine may not support this option, it is hard to tell more about the error with the information you provide.

var sel = document.createElement('select');
sel.name = 'drop1';
sel.id = 'Select1';

var cars = [
  "volvo",
  "saab",
  "mercedes",
  "audi"
];

var options_str = "";

cars.forEach( function(car) {
  options_str += '<option value="' + car + '">' + car + '</option>';
});

sel.innerHTML = options_str;


window.onload = function() {
  document.body.appendChild(sel);
};

For an extensive coverage review the contents of RFC2965. Of course that doesn't necessarily mean that all browsers behave exactly the same way.

However in general the rule for default Path if none specified in the cookie is the path in the URL from which the Set-Cookie header arrived. Similarly the default for the Domain is the full host name in the URL from which the Set-Cookie arrived.

Matching rules for the domain require the cookie Domain to match the host to which the request is being made. The cookie can specify a wider domain match by include *. in the domain attribute of Set-Cookie (this one area that browsers may vary). Matching the path (assuming the domain matches) is a simple matter that the requested path must be inside the path specified on the cookie. Typically session cookies are set with path=/ or path=/applicationName/ so the cookie is available to all requests into the application.

• Will a cookie for .example.com be available for www.example.com? Yes
• Will a cookie for .example.com be available for example.com? Don't Know
• Will a cookie for example.com be available for www.example.com? Shouldn't but... *
• Will a cookie for example.com be available for anotherexample.com? No
• Will www.example.com be able to set cookie for example.com? Yes
• Will www.example.com be able to set cookie for www2.example.com? No (Except via .example.com)
• Will www.example.com be able to set cookie for .com? No (Can't set a cookie this high up the namespace nor can you set one for something like .co.uk).

* I'm unable to test this right now but I have an inkling that at least IE7/6 would treat the path example.com as if it were .example.com.

$path = "C:\DemoFolder"

You can also use std::list instead of std::vector. list has a built-in function list::reverse for reversing elements.

Kinda late.But it just takes a bit of math.

  padding-bottom: 0;
  font-size: 11px;
  border: 1px dotted #222;
}

.bottom-content {
  background: #999;
  width: 100%; /* you need this for it to work */
  margin-left: -30px; /* will touch very left side */
  padding-right: 60px; /* will touch very right side */
}

<div class='content'>

  <p>A paragraph</p>
  <p>Another paragraph.</p>
  <p>No more content</p>


  <div class='bottom-content'>
      I want this div to ignore padding.
  </div>

I don't have Windows so I didn't test this in IE.

To read you should create an instance of ifsteam and not ofstream.

ifstream iusrfile;

You should open the file in read mode.

iusrfile.open("usrfile.txt", ifstream::in);

Also this statement is not correct.

cout<<iusrfile;

If you are trying to print the data you read from the file you should do:

cout<<usr;

You can read more about ifstream and its API here

I had problems with the image not resizing proportionately so the way I fixed it was using edge insets.

fooButton.contentEdgeInsets = UIEdgeInsetsMake(10, 15, 10, 15);

$user->data is an array of objects. Each element in the array has a name and value property (as well as others).

Try putting the 2nd foreach inside the 1st.

foreach($user->data as $mydata)
{
    echo $mydata->name . "\n";
    foreach($mydata->values as $values)
    {
        echo $values->value . "\n";

A SurfaceView is a custom view in Android that can be used to drawn inside it.

The main difference between a View and a SurfaceView is that a View is drawn in the UI Thread, which is used for all the user interaction.

If you want to update the UI rapidly enough and render a good amount of information in it, a SurfaceView is a better choice.

But there are a few technical insides to the SurfaceView:

1. They are not hardware accelerated.

2. Normal views are rendered when you call the methods invalidate or postInvalidate(), but this does not mean the view will be immediately updated (A VSYNC will be sent, and the OS decides when it gets updated. The SurfaceView can be immediately updated.

3. A SurfaceView has an allocated surface buffer, so it is more costly

This GitPro page does summarize the consequence of a git submodule update nicely

When you run git submodule update, it checks out the specific version of the project, but not within a branch. This is called having a detached head — it means the HEAD file points directly to a commit, not to a symbolic reference.
The issue is that you generally don’t want to work in a detached head environment, because it’s easy to lose changes.
If you do an initial submodule update, commit in that submodule directory without creating a branch to work in, and then run git submodule update again from the superproject without committing in the meantime, Git will overwrite your changes without telling you. Technically you won’t lose the work, but you won’t have a branch pointing to it, so it will be somewhat difficult to retrieve.

Note March 2013:

As mentioned in "git submodule tracking latest", a submodule now (git1.8.2) can track a branch.

# add submodule to track master branch
git submodule add -b master [URL to Git repo];

# update your submodule
git submodule update --remote 
# or (with rebase)
git submodule update --rebase --remote

See "git submodule update --remote vs git pull".

MindTooth's answer illustrate a manual update (without local configuration):

git submodule -q foreach git pull -q origin master

In both cases, that will change the submodules references (the gitlink, a special entry in the parent repo index), and you will need to add, commit and push said references from the main repo.
Next time you will clone that parent repo, it will populate the submodules to reflect those new SHA1 references.

The rest of this answer details the classic submodule feature (reference to a fixed commit, which is the all point behind the notion of a submodule).

To avoid this issue, create a branch when you work in a submodule directory with git checkout -b work or something equivalent. When you do the submodule update a second time, it will still revert your work, but at least you have a pointer to get back to.

Switching branches with submodules in them can also be tricky. If you create a new branch, add a submodule there, and then switch back to a branch without that submodule, you still have the submodule directory as an untracked directory:

So, to answer your questions:

can I create branches/modifications and use push/pull just like I would in regular repos, or are there things to be cautious about?

You can create a branch and push modifications.

WARNING (from Git Submodule Tutorial): Always publish (push) the submodule change before publishing (push) the change to the superproject that references it. If you forget to publish the submodule change, others won't be able to clone the repository.

how would I advance the submodule referenced commit from say (tagged) 1.0 to 1.1 (even though the head of the original repo is already at 2.0)

The page "Understanding Submodules" can help

Git submodules are implemented using two moving parts:

• the .gitmodules file and
• a special kind of tree object.

These together triangulate a specific revision of a specific repository which is checked out into a specific location in your project.

From the git submodule page

you cannot modify the contents of the submodule from within the main project

100% correct: you cannot modify a submodule, only refer to one of its commits.

This is why, when you do modify a submodule from within the main project, you:

• need to commit and push within the submodule (to the upstream module), and
• then go up in your main project, and re-commit (in order for that main project to refer to the new submodule commit you just created and pushed)

A submodule enables you to have a component-based approach development, where the main project only refers to specific commits of other components (here "other Git repositories declared as sub-modules").

A submodule is a marker (commit) to another Git repository which is not bound by the main project development cycle: it (the "other" Git repo) can evolves independently.
It is up to the main project to pick from that other repo whatever commit it needs.

However, should you want to, out of convenience, modify one of those submodules directly from your main project, Git allows you to do that, provided you first publish those submodule modifications to its original Git repo, and then commit your main project refering to a new version of said submodule.

But the main idea remains: referencing specific components which:

• have their own lifecycle
• have their own set of tags
• have their own development

The list of specific commits you are refering to in your main project defines your configuration (this is what Configuration Management is all about, englobing mere Version Control System)

If a component could really be developed at the same time as your main project (because any modification on the main project would involve modifying the sub-directory, and vice-versa), then it would be a "submodule" no more, but a subtree merge (also presented in the question Transferring legacy code base from cvs to distributed repository), linking the history of the two Git repo together.

Does that help understanding the true nature of Git Submodules?

You probably want to use the 'onbeforeunload' event. It will allow you call a function in the parent window from the child immediately before the child window closes.

So probably something like this:

window.onbeforeunload = function (e) {
    window.parent.functonToCallBeforeThisWindowCloses();
};

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

This answer builds on Zach Smith's answer by resetting the identity column as well:

1. Disabling all constraints
2. Iterating through all tables except those you choose to exclude
3. Deletes all rows from the table
4. Resets the identity column if one exists
5. Re-enables all constraints

Here is the query:

-- Disable all constraints in the database
EXEC sp_msforeachtable "ALTER TABLE ? NOCHECK CONSTRAINT all"

declare @catalog nvarchar(250);
declare @schema nvarchar(250);
declare @tbl nvarchar(250);
DECLARE i CURSOR LOCAL FAST_FORWARD FOR select
                                        TABLE_CATALOG,
                                        TABLE_SCHEMA,
                                        TABLE_NAME
                                        from INFORMATION_SCHEMA.TABLES
                                        where
                                        TABLE_TYPE = 'BASE TABLE'
                                        AND TABLE_NAME != 'sysdiagrams'
                                        AND TABLE_NAME != '__RefactorLog'
                                        -- Optional
                                        -- AND (TABLE_SCHEMA = 'dbo')

OPEN i;
FETCH NEXT FROM i INTO @catalog, @schema, @tbl;
WHILE @@FETCH_STATUS = 0
    BEGIN
        DECLARE @sql NVARCHAR(MAX) = N'DELETE FROM [' + @catalog + '].[' + @schema + '].[' + @tbl + '];'
        /* Make sure these are the commands you want to execute before executing */
        PRINT 'Executing statement: ' + @sql
        --EXECUTE sp_executesql @sql

        -- Reset identity counter if one exists
        IF ((SELECT OBJECTPROPERTY( OBJECT_ID(@catalog + '.' + @schema + '.' + @tbl), 'TableHasIdentity')) = 1)
        BEGIN
            SET @sql = N'DBCC CHECKIDENT ([' + @catalog + '.' + @schema + '.' + @tbl + '], RESEED, 0)'
            PRINT 'Executing statement: ' + @sql
            --EXECUTE sp_executesql @sql
        END     

        FETCH NEXT FROM i INTO @catalog, @schema, @tbl;
    END
CLOSE i;
DEALLOCATE i;

-- Re-enable all constraints again
EXEC sp_msforeachtable "ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all"

We can use contains method to check if an item exists if we have provided the implementation of equals and hashCode else object reference will be used for equality comparison. Also in case of a list contains is O(n) operation where as it is O(1) for HashSet so better to use later. In Java 8 we can use streams also to check item based on its equality or based on a specific property.

Java 8

CurrentAccount conta5 = new CurrentAccount("João Lopes", 3135);
boolean itemExists = lista.stream().anyMatch(c -> c.equals(conta5)); //provided equals and hashcode overridden
System.out.println(itemExists); // true

String nameToMatch = "Ricardo Vitor";
boolean itemExistsBasedOnProp = lista.stream().map(CurrentAccount::getName).anyMatch(nameToMatch::equals);
System.out.println(itemExistsBasedOnProp); //true

I found the following article to be very helpful:

https://weblog.west-wind.com/posts/2015/Apr/29/Adding-minimal-OWIN-Identity-Authentication-to-an-Existing-ASPNET-MVC-Application#MinimalCodeSummary

In my case, I had to set the following before Owin authentication would work instead of windows authentication:

<system.web>   
    <authentication mode="None" />   
<system.web>

@BindView(R.id.checkbox_id) // if you are using Butterknife
CheckBox yourCheckBox;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.your_activity); 
    yourCheckBox = (CheckBox)findViewById(R.id.checkbox_id);// If your are not using Butterknife (the traditional way)

    yourCheckBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            yourObject.setYourProperty(yourCheckBox.isChecked()); //yourCheckBox.isChecked() is the method to know if the checkBox is checked
            Log.d(TAG, "onClick: yourCheckBox = " + yourObject.getYourProperty() );
        }
    });
}

Obviously you have to make your XML with the id of your checkbox :

<CheckBox
    android:id="@+id/checkbox_id"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Your label"
    />

So, the method to know if the check box is checked is : (CheckBox) yourCheckBox.isChecked() it returns true if the check box is checked.

Swift 5 - This works for me:

 func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {

        let selectedCell:UITableViewCell = tableView.cellForRow(at: indexPath as IndexPath)!
        selectedCell.contentView.backgroundColor = .red
    }



    func tableView(_ tableView: UITableView, didDeselectRowAt indexPath: IndexPath) {

        let cellToDeSelect:UITableViewCell = tableView.cellForRow(at: indexPath as IndexPath)!
        cellToDeSelect.contentView.backgroundColor = .clear
    }

I know it's not your specific problem, but I faced the same symptoms when I configured a static IP address in the network adapter settings and forgot to enter a "Default Gateway".

Leaving the field blank, the network icon shows an Internet connection, and I could ping internal servers but not external ones, so I assumed it was a DNS problem. NSLookup still worked, but of course, ping failed to find the server (again, seemed like a DNS issue.) Anyway, one more thing to check. =P

To get your radio button to list horizontally , just add

RepeatDirection="Horizontal"

to your .aspx file where the asp:radiobuttonlist is being declared.

I am just doing this without even trying it. Would this work?

myDiv = getElementById("myDiv");
myDiv.querySelectorAll(this.id + " > .foo");

Give it a try, maybe it works maybe not. Apolovies, but I am not on a computer now to try it (responding from my iPhone).

From the jQuery API Document

While JavaScript provides the load event for executing code when a page is rendered, this event does not get triggered until all assets such as images have been completely received. In most cases, the script can be run as soon as the DOM hierarchy has been fully constructed. The handler passed to .ready() is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers and run other jQuery code. When using scripts that rely on the value of CSS style properties, it's important to reference external stylesheets or embed style elements before referencing the scripts.

In cases where code relies on loaded assets (for example, if the dimensions of an image are required), the code should be placed in a handler for the load event instead.

Answer to the second question -

No, they are identical as long as you are not using jQuery in no conflict mode.

You can also right click on the project -> Android Tools -> Fix Project Properties. That should cause the R.java class to be re-generated.

Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms.

In the Java context, we first need to make a distinction between "copying a value" and "copying an object".

int a = 1;
int b = a;     // copying a value
int[] s = new int[]{42};
int[] t = s;   // copying a value (the object reference for the array above)

StringBuffer sb = new StringBuffer("Hi mom");
               // copying an object.
StringBuffer sb2 = new StringBuffer(sb);

In short, an assignment of a reference to a variable whose type is a reference type is "copying a value" where the value is the object reference. To copy an object, something needs to use new, either explicitly or under the hood.

Now for "shallow" versus "deep" copying of objects. Shallow copying generally means copying only one level of an object, while deep copying generally means copying more than one level. The problem is in deciding what we mean by a level. Consider this:

public class Example {
    public int foo;
    public int[] bar;
    public Example() { };
    public Example(int foo, int[] bar) { this.foo = foo; this.bar = bar; };
}

Example eg1 = new Example(1, new int[]{1, 2});
Example eg2 = ... 

The normal interpretation is that a "shallow" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to the same array as in the original; e.g.

Example eg2 = new Example(eg1.foo, eg1.bar);

The normal interpretation of a "deep" copy of eg1 would be a new Example object whose foo equals 1 and whose bar field refers to a copy of the original array; e.g.

Example eg2 = new Example(eg1.foo, Arrays.copy(eg1.bar));

(People coming from a C / C++ background might say that a reference assignment produces a shallow copy. However, that's not what we normally mean by shallow copying in the Java context ...)

Two more questions / areas of uncertainty exist:

• How deep is deep? Does it stop at two levels? Three levels? Does it mean the whole graph of connected objects?

• What about encapsulated data types; e.g. a String? A String is actually not just one object. In fact, it is an "object" with some scalar fields, and a reference to an array of characters. However, the array of characters is completely hidden by the API. So, when we talk about copying a String, does it make sense to call it a "shallow" copy or a "deep" copy? Or should we just call it a copy?

Finally, clone. Clone is a method that exists on all classes (and arrays) that is generally thought to produce a copy of the target object. However:

• The specification of this method deliberately does not say whether this is a shallow or deep copy (assuming that is a meaningful distinction).

• In fact, the specification does not even specifically state that clone produces a new object.

Here's what the javadoc says:

"Creates and returns a copy of this object. The precise meaning of "copy" may depend on the class of the object. The general intent is that, for any object x, the expression x.clone() != x will be true, and that the expression x.clone().getClass() == x.getClass() will be true, but these are not absolute requirements. While it is typically the case that x.clone().equals(x) will be true, this is not an absolute requirement."

Note, that this is saying that at one extreme the clone might be the target object, and at the other extreme the clone might not equal the original. And this assumes that clone is even supported.

In short, clone potentially means something different for every Java class.

Some people argue (as @supercat does in comments) that the Java clone() method is broken. But I think the correct conclusion is that the concept of clone is broken in the context of OO. AFAIK, it is impossible to develop a unified model of cloning that is consistent and usable across all object types.

You can try something like process.argv, that is if you are using node.js to run the program.
console.log(process.argv) => Would print an array containing

[                                                                                                                                                                                          
  '/usr/bin/node',                                                                                                                                                                         
  '/home/user/path/filename.js',                                                                                                                                            
  'your_input'                                                                                                                                                                                   
]

You get the user provided input via array index, i.e., console.log(process.argv[3]) This should provide you with the input which you can store.

Example:

var somevariable = process.argv[3]; // input one
var somevariable2 = process.argv[4]; // input two

console.log(somevariable);
console.log(somevariable2);

If you are building a command-line program then the npm package yargs would be really helpful.

You can also use the following to include the TIME portion in your query:

SELECT EMP_NAME
     , DEPT
  FROM EMPLOYEE 
 WHERE TIME_CREATED >= TO_DATE('26/JAN/2011 00:00:00', 'dd/mon/yyyy HH24:MI:SS');

You can use splice to remove objects or values from an array.

Let's consider an array of length 5, with values 10,20,30,40,50, and I want to remove the value 30 from it.

var array = [10,20,30,40,50];_x000D_
if (array.indexOf(30) > -1) {_x000D_
   array.splice(array.indexOf(30), 1);_x000D_
}_x000D_
console.log(array); // [10,20,40,50]

The new official AWS CLI natively supports most of the functionality of s3cmd. I'd previously been using s3cmd or the ruby AWS SDK to do things like this, but the official CLI works great for this.

I always liked going after it directly:

I was actually running into some strange errors with mp4's a while ago. What fixed it for me was re-encoding the video using known supported codecs (H.264 & MP3).

I actually used the VLC player to do so and it worked fine afterward. I converted using the mentioned codecs H.264/MP3. That solved it for me.

Maybe the problem is not in the format but in the JavaScript implementation of the play/ pause methods. May I suggest visiting the following link where Google developer explains it in a good way?

Additionally, you could choose to use the newer webp format, which Chrome supports out of the box, but be careful with other browsers. Check the support for it before implementation. Here's a link that describes the mentioned format.

On that note: I've created a small script that easily converts all standard formats to webp. You can easily configure it to fit your needs. Here's the Github repo of the same projects.

From effective java book

1. whenever a class manages its own memory, the programmer should be alert for memory leaks

.

public class Stack {
private Object[] elements;
private int size = 0;
private static final int DEFAULT_INITIAL_CAPACITY = 16;

public Stack() {
    elements = new Object[DEFAULT_INITIAL_CAPACITY];
}

public void push(Object e) {
    ensureCapacity();
    elements[size++] = e;
}

public Object pop() {
    if (size == 0)
        throw new EmptyStackException();
    return elements[--size];
}

/**
 * Ensure space for at least one more element, roughly doubling the capacity
 * each time the array needs to grow.
 */
private void ensureCapacity() {
    if (elements.length == size)
        elements = Arrays.copyOf(elements, 2 * size + 1);
}

}

Can you spot the memory leak? So where is the memory leak? If a stack grows and then shrinks, the objects that were popped off the stack will not be garbage collected, even if the program using the stack has no more references to them. This is because the stack maintains obsolete references to these objects. An obsolete reference is simply a reference that will never be dereferenced again. In this case, any references outside of the “active portion” of the element array are obsolete. The active portion consists of the elements whose index is less than size.

You can do that just using CSS.

You'll need to place another tag inside the <a> and then you can change the CSS background-image attribute on a:hover.

i.e.

HTML:

<a href="#" id="name">
  <span>&nbsp;</span> 
</a>

CSS:

a#name span{
  background-image:url(image/path);
}

a#name:hover span{
  background-image:url(another/image/path);
}
