It seems to me that what you really want, is to customize the look of the captions. This is most easily done using the caption package. For instructions how to use this package, see the manual (PDF). You would probably need to create your own custom caption format, as described in chapter 4 in the manual.

Edit: Tested with MikTex:

\documentclass{report}

\usepackage{color}
\usepackage{xcolor}
\usepackage{listings}

\usepackage{caption}
\DeclareCaptionFont{white}{\color{white}}
\DeclareCaptionFormat{listing}{\colorbox{gray}{\parbox{\textwidth}{#1#2#3}}}
\captionsetup[lstlisting]{format=listing,labelfont=white,textfont=white}

% This concludes the preamble

\begin{document}

\begin{lstlisting}[label=some-code,caption=Some Code]
public void here() {
    goes().the().code()
}
\end{lstlisting}

\end{document}

Result:

It turns out that lstlisting is able to format code nicely, but requires a lot of tweaking.

Wikibooks has a good example for the parameters you can tweak.

you can use convert function :

Select convert(int,[Column1])

I found that when I created a scene via the three.js editor, I not only had to use the correct answer's code (above), to set up the renderer with an alpha value and the clear color, I had to go into the app.json file and find the "Scene" Object's "background" attribute and set it to: "background: null".

The export from Three.js editor had it originally set to "background": 0

Using just try_files didn't work for me - it caused a rewrite or internal redirection cycle error in my logs.

The Nginx docs had some additional details:

http://nginx.org/en/docs/http/ngx_http_core_module.html#try_files

So I ended up using the following:

root /var/www/mysite;

location / {
    try_files $uri /base.html;
}

location = /base.html {
    expires 30s;
}

What is JNDI ?

JNDI stands for Java Naming and Directory Interface. It comes standard with J2EE.

What is its basic use?

With this API, you can access many types of data, like objects, devices, files of naming and directory services, eg. it is used by EJB to find remote objects. JNDI is designed to provide a common interface to access existing services like DNS, NDS, LDAP, CORBA and RMI.

When it is used?

You can use the JNDI to perform naming operations, including read operations and operations for updating the namespace. The following operations are described here.

I think this first failed because you are ordering value which is null. If Delivery is a foreign key associated table then you should include this table first, example below:

var itemList = from t in ctn.Items.Include(x=>x.Delivery)
                    where !t.Items && t.DeliverySelection
                    orderby t.Delivery.SubmissionDate descending
                    select t;

Remove trailing whitespace in .gitignore

Also, make sure you have no trailing whitespace in your .gitignore. I got to this question because I was searching for an answer, then I had a funny feeling I should open the editor instead of just cat'ing .gitignore. Removed a single extra space from the end and poof it works now :)

No it is not possible in java (Maybe in java 8 it will be avilable). Except the case when you extend in a tree. For example:

class A
class B extends A
class C extends B

asort() - Maintains key association: yes.

sort() - Maintains key association: no.

Add this to your project file:

CONFIG += console

For scoping purpose, I use:

custom_object = None

What worked finally for me and also compatible with 2.0 is to add in my layout (or in model)

<?php echo $this->element('sql_dump');?>

It is also depending on debug variable setted into Config/core.php

use

textarea{
  visibility:hidden;
}

I have already upvoted the @dasblinkenlight answer since the Median of Medians algorithm in fact solves this problem in O(n) time. I only want to add that this problem could be solved in O(n) time by using heaps also. Building a heap could be done in O(n) time by using the bottom-up. Take a look to the following article for a detailed explanation Heap sort

Supposing that your array has N elements, you have to build two heaps: A MaxHeap that contains the first N/2 elements (or (N/2)+1 if N is odd) and a MinHeap that contains the remaining elements. If N is odd then your median is the maximum element of MaxHeap (O(1) by getting the max). If N is even, then your median is (MaxHeap.max()+MinHeap.min())/2 this takes O(1) also. Thus, the real cost of the whole operation is the heaps building operation which is O(n).

BTW this MaxHeap/MinHeap algorithm works also when you don't know the number of the array elements beforehand (if you have to resolve the same problem for a stream of integers for e.g). You can see more details about how to resolve this problem in the following article Median Of integer streams

I had this problem too, and tried all methods. I found that only this method works (iOS 5.x): UIWebView iOS5 changing user-agent

The principle is to set the user agent permanently in the user settings. This works; Webview sends the given header. Just two lines of code:

NSDictionary *dictionary = [NSDictionary dictionaryWithObjectsAndKeys:@"Mozilla/Whatever version 913.6.beta", @"UserAgent", nil];
[[NSUserDefaults standardUserDefaults] registerDefaults:dictionary];

Setting User-Agent, or User_Agent in the mutable request, or overriding the setValue in the NSHttpRequest by swizzling, - I tried all that and controlled the results with wireshark, and none of that seems to work, because Webview still uses the user agent value from the user defaults, no matter what you try to set in the NSHttpRequest.

I would use the yattag library. I think it's the most pythonic way:

from yattag import Doc

doc, tag, text = Doc().tagtext()

with tag('food'):
    with tag('name'):
        text('French Breakfast')
    with tag('price', currency='USD'):
        text('6.95')
    with tag('ingredients'):
        for ingredient in ('baguettes', 'jam', 'butter', 'croissants'):
            with tag('ingredient'):
                text(ingredient)


print(doc.getvalue())

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

Yes, you can, without adding a new column. You have to be careful to do it correctly in order to avoid corrupting the database, so you should completely back up your database before trying this.

for your specific example:

CREATE TABLE child(
  id INTEGER PRIMARY KEY,
  parent_id INTEGER,
  description TEXT
);

--- create the table we want to reference
create table parent(id integer not null primary key);

--- now we add the foreign key
pragma writable_schema=1;
update SQLITE_MASTER set sql = replace(sql, 'description TEXT)',
    'description TEXT, foreign key (parent_id) references parent(id))'
) where name = 'child' and type = 'table';

--- test the foreign key
pragma foreign_keys=on;
insert into parent values(1);
insert into child values(1, 1, 'hi'); --- works
insert into child values(2, 2, 'bye'); --- fails, foreign key violation

or more generally:

pragma writable_schema=1;

// replace the entire table's SQL definition, where new_sql_definition contains the foreign key clause you want to add
UPDATE SQLITE_MASTER SET SQL = new_sql_definition where name = 'child' and type = 'table';

// alternatively, you might find it easier to use replace, if you can match the exact end of the sql definition
// for example, if the last column was my_last_column integer not null:
UPDATE SQLITE_MASTER SET SQL = replace(sql, 'my_last_column integer not null', 'my_last_column integer not null, foreign key (col1, col2) references other_table(col1, col2)') where name = 'child' and type = 'table';

pragma writable_schema=0;

Either way, you'll probably want to first see what the SQL definition is before you make any changes:

select sql from SQLITE_MASTER where name = 'child' and type = 'table';

If you use the replace() approach, you may find it helpful, before executing, to first test your replace() command by running:

select replace(sql, ...) from SQLITE_MASTER where name = 'child' and type = 'table';

The three dots represent the Spread Operator in ES6. It allows us to do quite a few things in Javascript:

1. Concatenate arrays

   var shooterGames = ['Call of Duty', 'Far Cry', 'Resident Evil'];
   var racingGames = ['Need For Speed', 'Gran Turismo', 'Burnout'];
   var games = [...shooterGames, ...racingGames];
   
   console.log(games)  // ['Call of Duty', 'Far Cry', 'Resident Evil',  'Need For Speed', 'Gran Turismo', 'Burnout']
   

2. Destructuring an array

     var shooterGames = ['Call of Duty', 'Far Cry', 'Resident Evil'];
     var [first, ...remaining] = shooterGames;
     console.log(first); //Call of Duty
     console.log(remaining); //['Far Cry', 'Resident Evil']
   

3. Combining two objects

   var myCrush = {
     firstname: 'Selena',
     middlename: 'Marie'
   };
   
   var lastname = 'my last name';
   
   var myWife = {
     ...myCrush,
     lastname
   }
   
   console.log(myWife); // {firstname: 'Selena',
                        //   middlename: 'Marie',
                        //   lastname: 'my last name'}
   

There's another use for the three dots which is known as Rest Parameters and it makes it possible to take all of the arguments to a function in as one array.

4. Function arguments as array

    function fun1(...params) { 
   
    }  
   

If you are using Java configuration in a spring-data-jpa project, make sure you are scanning the package that the entity is in. For example, if the entity lived com.foo.myservice.things then the following configuration annotation below would not pick it up.

You could fix it by loosening it up to just com.foo.myservice (of course, keep in mind any other effects of broadening your scope to scan for entities).

@Configuration
@EnableJpaAuditing
@EnableJpaRepositories("com.foo.myservice.repositories")
public class RepositoryConfiguration {
}

For Java 1.8 users that are getting a warning when trying to reference the @PostConstruct annotation, I ended up instead piggybacking off the @Scheduled annotation which you can do if you already have an @Scheduled job with fixedRate or fixedDelay.

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

@EnableScheduling
@Component
public class ScheduledTasks {

private static final Logger LOGGER = LoggerFactory.getLogger(ScheduledTasks.class);

private static boolean needToRunStartupMethod = true;

    @Scheduled(fixedRate = 3600000)
    public void keepAlive() {
        //log "alive" every hour for sanity checks
        LOGGER.debug("alive");
        if (needToRunStartupMethod) {
            runOnceOnlyOnStartup();
            needToRunStartupMethod = false;
        }
    }

    public void runOnceOnlyOnStartup() {
        LOGGER.debug("running startup job");
    }

}

Bootstrap 4.1 provides a class named disabled and aria-disabled="true" attribute.

example"

<a href="#" 
        class="btn btn-primary btn-lg disabled" 
        tabindex="-1" 
        role="button" aria-disabled="true"
>
    Primary link
</a>

More is on getbootstrap.com

So if you want to make it dynamically, and you don't want to care if it is button or ancor than in JS script you need something like that

   let $btn=$('.myClass');
   $btn.attr('disabled', true);
   if ($btn[0].tagName == 'A'){
        $btn.off();
        $btn.addClass('disabled');
        $btn.attr('aria-disabled', true);
   }

But be carefull

The solution only works on links with classes btn btn-link.

Sometimes bootstrap recommends using card-link class, in this case solution will not work.

Some solution is first to copy() the file (as mentioned above) and when the destination file exists - unlink() file from previous localization. Additionally you can validate the MD5 checksum before unlinking to be sure

A "Broken Pipe" error occurs when you try to write to a pipe that has been closed on the other end. Since the code you've shown doesn't involve any pipes directly, I suspect you're doing something outside of Python to redirect the standard output of the Python interpreter to somewhere else. This could happen if you're running a script like this:

python foo.py | someothercommand

The issue you have is that someothercommand is exiting without reading everything available on its standard input. This causes your write (via print) to fail at some point.

I was able to reproduce the error with the following command on a Linux system:

python -c 'for i in range(1000): print i' | less

If I close the less pager without scrolling through all of its input (1000 lines), Python exits with the same IOError you have reported.

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

Use JSONP.

jQuery:

$.ajax({
     url:"testserver.php",
     dataType: 'jsonp', // Notice! JSONP <-- P (lowercase)
     success:function(json){
         // do stuff with json (in this case an array)
         alert("Success");
     },
     error:function(){
         alert("Error");
     }      
});

PHP:

<?php
$arr = array("element1","element2",array("element31","element32"));
$arr['name'] = "response";
echo $_GET['callback']."(".json_encode($arr).");";
?>

The echo might be wrong, it's been a while since I've used php. In any case you need to output callbackName('jsonString') notice the quotes. jQuery will pass it's own callback name, so you need to get that from the GET params.

And as Stefan Kendall posted, $.getJSON() is a shorthand method, but then you need to append 'callback=?' to the url as GET parameter (yes, value is ?, jQuery replaces this with its own generated callback method).

Put the line $this->db->order_by("course_name","desc"); at top of your query. Like

$this->db->order_by("course_name","desc");$this->db->select('*');
$this->db->where('tennant_id',$tennant_id);
$this->db->from('courses');
$query=$this->db->get();
return $query->result();

I recently ran into a problem with a UICommand not invoking in a JSF 1.2 application using IBM Extended Faces Components.

I had a command button on a row of a datatable (the extended version, so <hx:datatable>) and the UICommand would not fire from certain rows from the table (the rows that would not fire were the rows greater than the default row display size).

I had a drop-down component for selecting number of rows to display. The value backing this field was in RequestScope. The data backing the table itself was in a sort of ViewScope (in reality, temporarily in SessionScope).

If the row display was increased via the control which value was also bound to the datatable's rows attribute, none of the rows displayed as a result of this change could fire the UICommand when clicked.

Placing this attribute in the same scope as the table data itself fixed the problem.

I think this is alluded to in BalusC #4 above, but not only did the table value need to be View or Session scoped but also the attribute controlling the number of rows to display on that table.

To load your data in WebView. Call loadData() method of WebView

webView.loadData(yourData, "text/html; charset=utf-8", "UTF-8");

You can check this example

http://developer.android.com/reference/android/webkit/WebView.html

A view is simply any SELECT query that has been given a name and saved in the database. For this reason, a view is sometimes called a named query or a stored query. To create a view, you use the SQL syntax:

     CREATE OR REPLACE VIEW <view_name> AS
     SELECT <any valid select query>;

Any extension page (except content scripts) has direct access to the background page via chrome.extension.getBackgroundPage().

That means, within the popup page, you can just do:

chrome.extension.getBackgroundPage().console.log('foo');

To make it easier to use:

var bkg = chrome.extension.getBackgroundPage();
bkg.console.log('foo');

Now if you want to do the same within content scripts you have to use Message Passing to achieve that. The reason, they both belong to different domains, which make sense. There are many examples in the Message Passing page for you to check out.

Hope that clears everything.

That's generally controlled by the profile associated with the user Tomcat is connecting as.

SQL> SELECT PROFILE, LIMIT FROM DBA_PROFILES WHERE RESOURCE_NAME = 'IDLE_TIME';

PROFILE                        LIMIT
------------------------------ ----------------------------------------
DEFAULT                        UNLIMITED

SQL> SELECT PROFILE FROM DBA_USERS WHERE USERNAME = USER;

PROFILE
------------------------------
DEFAULT

So the user I'm connected to has unlimited idle time - no time out.

For me, I was writing to a file that is opened in Excel.

Replace the favicon.ico in your public folder with yours, that should get you going.

Note that datalist is not the same as a select. It allows users to enter a custom value that is not in the list, and it would be impossible to fetch an alternate value for such input without defining it first.

Possible ways to handle user input are to submit the entered value as is, submit a blank value, or prevent submitting. This answer handles only the first two options.

If you want to disallow user input entirely, maybe select would be a better choice.

To show only the text value of the option in the dropdown, we use the inner text for it and leave out the value attribute. The actual value that we want to send along is stored in a custom data-value attribute:

To submit this data-value we have to use an <input type="hidden">. In this case we leave out the name="answer" on the regular input and move it to the hidden copy.

<input list="suggestionList" id="answerInput">
<datalist id="suggestionList">
    <option data-value="42">The answer</option>
</datalist>
<input type="hidden" name="answer" id="answerInput-hidden">

This way, when the text in the original input changes we can use javascript to check if the text also present in the datalist and fetch its data-value. That value is inserted into the hidden input and submitted.

document.querySelector('input[list]').addEventListener('input', function(e) {
    var input = e.target,
        list = input.getAttribute('list'),
        options = document.querySelectorAll('#' + list + ' option'),
        hiddenInput = document.getElementById(input.getAttribute('id') + '-hidden'),
        inputValue = input.value;

    hiddenInput.value = inputValue;

    for(var i = 0; i < options.length; i++) {
        var option = options[i];

        if(option.innerText === inputValue) {
            hiddenInput.value = option.getAttribute('data-value');
            break;
        }
    }
});

The id answer and answer-hidden on the regular and hidden input are needed for the script to know which input belongs to which hidden version. This way it's possible to have multiple inputs on the same page with one or more datalists providing suggestions.

Any user input is submitted as is. To submit an empty value when the user input is not present in the datalist, change hiddenInput.value = inputValue to hiddenInput.value = ""

You definitely should not need the debug version of the CRT if you're compiling in "release" mode. You can tell they're the debug versions of the DLLs because they end with a d.

More to the point, the debug version is not redistributable, so it's not as simple as "packaging" it with your executable, or zipping up those DLLs.

Check to be sure that you're compiling all components of your application in "release" mode, and that you're linking the correct version of the CRT and any other libraries you use (e.g., MFC, ATL, etc.).

You will, of course, require msvcr100.dll (note the absence of the d suffix) and some others if they are not already installed. Direct your friends to download the Visual C++ 2010 Redistributable (or x64), or include this with your application automatically by building an installer.

If you used Create React App, you can set an environment variable using a .env file. The documentation is here:

https://facebook.github.io/create-react-app/docs/adding-custom-environment-variables

Basically do something like this in the .env file at the project root.

REACT_APP_NOT_SECRET_CODE=abcdef

Note that the variable name must start with REACT_APP_

You can access it from your component with

process.env.REACT_APP_NOT_SECRET_CODE

One of my clients was facing the same issue. Following steps are taken to fix this.

 (1) Open Run. 

 (2) Type Services.msc

 (3) Select ASP.NET State Service

 (4) Right Click and Start it.

If the difference between endTime and startTime is greater than or equal to 60 Minutes , the statement:endTime.Subtract(startTime).Minutes; will always return (minutesDifference % 60). Obviously which is not desired when we are only talking about minutes (not hours here).
Here are some of the ways if you want to get total number of minutes(in different typecasts):

// Default value that is returned is of type *double* 
double double_minutes = endTime.Subtract(startTime).TotalMinutes; 
int integer_minutes = (int)endTime.Subtract(startTime).TotalMinutes; 
long long_minutes = (long)endTime.Subtract(startTime).TotalMinutes; 
string string_minutes = (string)endTime.Subtract(startTime).TotalMinutes; 

If you do it in a migration then you could probably do it like this:

# Make sure no null value exist
MyModel.where(date_column: nil).update_all(date_column: Time.now)

# Change the column to not allow null
change_column :my_models, :date_column, :datetime, null: false

Class.getSimpleName()

Returns the simple name of the underlying class as given in the source code. Returns an empty string if the underlying class is anonymous.

The simple name of an array is the simple name of the component type with "[]" appended. In particular the simple name of an array whose component type is anonymous is "[]".

It is actually stripping the package information from the name, but this is hidden from you.

Decimal datatype

• Unlike hardware based binary floating point, the decimal module has a user alterable precision (defaulting to 28 places) which can be as large as needed for a given problem.

When you use re.split and the split pattern contains capturing groups, the groups are retained in the output. If you don't want this, use a non-capturing group instead.

Why unicode? Because ASCII has just 127 characters. Those from 128 to 255 differ in different countries, that's why there are codepages. So they said lets have up to 1114111 characters. So how do you store the highest codepoint? You'll need to store it using 21 bits, so you'll use a DWORD having 32 bits with 11 bits wasted. So if you use a DWORD to store a unicode character, it is the easiest way because the value in your DWORD matches exactly the codepoint. But DWORD arrays are of course larger than WORD arrays and of course even larger than BYTE arrays. That's why there is not only utf-32, but also utf-16. But utf-16 means a WORD stream, and a WORD has 16 bits so how can the highest codepoint 1114111 fit into a WORD? It cannot! So they put everyything higher than 65535 into a DWORD which they call a surrogate-pair. Such surrogate-pair are two WORDS and can get detected by looking at the first 6 bits. So what about utf-8? It is a byte array or byte stream, but how can the highest codepoint 1114111 fit into a byte? It cannot! Okay, so they put in also a DWORD right? Or possibly a WORD, right? Almost right! They invented utf-8 sequences which means that every codepoint higher than 127 must get encoded into a 2-byte, 3-byte or 4-byte sequence. Wow! But how can we detect such sequences? Well, everything up to 127 is ASCII and is a single byte. What starts with 110 is a two-byte sequence, what starts with 1110 is a three-byte sequence and what starts with 11110 is a four-byte sequence. The remaining bits of these so called "startbytes" belong to the codepoint. Now depending on the sequence, following bytes must follow. A following byte starts with 10, the remaining bits are 6 bits of payload bits and belong to the codepoint. Concatenate the payload bits of the startbyte and the following byte/s and you'll have the codepoint. That's all the magic of utf-8.

BCD - Binary-coded Decimal - representations are exact. They are not very space-efficient, but that's a trade-off you have to make for accuracy in this case.

You can use JSON.parse for that:

JSON.parse("true"); //returns boolean true

I find answer. Thanks all but right answer next:

$("#myModal").on("hidden", function () {
  $('#result').html('yes,result');
});

Events here http://bootstrap-ru.com/javascript.php#modals

UPD

For Bootstrap 3.x need use hidden.bs.modal:

$("#myModal").on("hidden.bs.modal", function () {
  $('#result').html('yes,result');
});

This method work for me:

DELIMITER $$
DROP PROCEDURE IF EXISTS db.test $$
CREATE PROCEDURE db.test(IN id INT(12),IN NAME VARCHAR(255))
 BEGIN
 INSERT INTO USER VALUES(id,NAME);
 END$$
DELIMITER ;

I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:

        <p:pickList id="formPickList" 
                    value="#{mediaDetail.availableMedia}" 
                    converter="MediaPicklistConverter" 
                    widgetVar="formsPicklistWidget" 
                    var="mediaFiles" 
                    itemLabel="#{mediaFiles.mediaTitle}" 
                    itemValue="#{mediaFiles}" >
            <f:facet name="sourceCaption">Available Media</f:facet>
            <f:facet name="targetCaption">Chosen Media</f:facet>
        </p:pickList>

        <p:commandButton id="viewStream_btn" 
                         value="Stream chosen media" 
                         icon="fa fa-download"
                         ajax="true"
                         action="#{mediaDetail.prepareStreams}"                                              
                         update=":streamDialogPanel"
                         oncomplete="PF('streamingDialog').show()"
                         styleClass="ui-priority-primary"
                         style="margin-top:5px" >
            <p:ajax process="formPickList"  />
        </p:commandButton>

The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.

As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.

The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" /> bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.

Happy coding!

Add this to your .htaccess:

IndexOptions +Charset=UTF-8

Or, if you have administrator rights, you could set it globally by editing httpd.conf and adding:

AddDefaultCharset UTF-8

(You can use AddDefaultCharset in .htaccess too, but it won’t affect Apache-generated directory listings that way.)

This problem is quite easily solved using min-width and max-width within a css rule.

HTML

<table>
  <tr>
    <td class="name">Peter</td>
    <td class="hobby">Photography</td>
    <td class="comment">A long comment about something...</td>
  </td>
</table>

CSS

.name {
  max-width: 80px;
  min-width: 80px;
}

This will force the first column to be 80px wide. Usually I only use max-width without min-width to reign in text that is very occasionally too long from creating a table that has a super wide column that is mostly empty. The OP's question was about setting to a fixed width though, hence both rules together. On many browsers width:80px; in CSS is ignored for table columns. Setting the width within the HTML does work, but is not the way you should do things.

I would recommend using min and max width rules, and not set them the same but rather set a range. This way the table can do it's thing, but you can give it some hints on what to do with overly long content.

If I want to keep the text from wrapping and increasing the height of a row - but still make it possible for a user to see the full text, I use white-space: nowrap; on the main rule, then apply a hover rule that removes the width and nowrap rules so that the user can see the full content when they over their mouse over it. Something like this:

CSS

.name {
  max-width: 80px;
  white-space: nowrap;
  overflow: hidden;
}
.name:hover {
  max-width: none;
  white-space: normal;
  overflow:auto;
}

It just depends on exactly what you are trying to achieve. I hope this helps someone. PS As an aside, for iOS there is a fix for hover not working - see CSS Hover Not Working on iOS Safari and Chrome

Do like jQuery does! (the essence)

function parseJSON(data) {
    return window.JSON && window.JSON.parse ? window.JSON.parse( data ) : (new Function("return " + data))(); 
}
// testing
obj = parseJSON('{"name":"John"}');
alert(obj.name);

This way you don't need any external library and it still works on old browsers.

If you (or other searchers of this question) were actually interested in creating a contiguous array to fill with integers, consider bytearray and memoryivew:

# cast() is available starting Python 3.3
size = 10**6 
ints = memoryview(bytearray(size)).cast('i') 

ints.contiguous, ints.itemsize, ints.shape
# (True, 4, (250000,))

ints[0]
# 0

ints[0] = 16
ints[0]
# 16

Another way to do this is to add the new characters to the string as follows:

Dim str As String

str = ""

To append text to your string this way:

str = str & "and this is more text"

As already mentioned, HTTP itself doesn't impose any hard-coded limit on request length; but browsers have limits ranging on the 2048 character allowed in the GET method.

List<YourModel> data = new List<YourModel>();
DataTable dataTable = Newtonsoft.Json.JsonConvert.DeserializeObject<DataTable>(Newtonsoft.Json.JsonConvert.SerializeObject(data));

You might do it this way:

function asoccArrayValueWithNumKey(&$arr, $key) {
   if (!(count($arr) > $key)) return false;
   reset($array);
   $aux   = -1;
   $found = false;
   while (($auxKey = key($array)) && !$found) {
      $aux++;
      $found = ($aux == $key);
   }
   if ($found) return $array[$auxKey];
   else return false;
}

$val = asoccArrayValueWithNumKey($array, 0);
$val = asoccArrayValueWithNumKey($array, 1);
etc...

Haven't tryed the code, but i'm pretty sure it will work.

Good luck!

You need to run the script like this:

groovy helloworld.groovy

If you use OmniFaces you can also use it's EL functions like of:formatDate() to format Date objects. You would use it like this:

<h:outputText value="#{of:formatDate(someBean.dateField, 'dd.MM.yyyy HH:mm')}" />

This way you can not only use it for output but also to pass it on to other JSF components.

Set the auto increment field to NULL or 0 if you want it to be auto magically assigned...

Couldn't you just have your class expose a Dictionary object? Instead of "attaching more properties to the object", you could simply insert your data (with some identifier) into the dictionary at run time.

Although Reed Copsey and Marc Gravell already described about IQueryable (and also IEnumerable) enough,mI want to add little more here by providing a small example on IQueryable and IEnumerable as many users asked for it

Example: I have created two table in database

   CREATE TABLE [dbo].[Employee]([PersonId] [int] NOT NULL PRIMARY KEY,[Gender] [nchar](1) NOT NULL)
   CREATE TABLE [dbo].[Person]([PersonId] [int] NOT NULL PRIMARY KEY,[FirstName] [nvarchar](50) NOT NULL,[LastName] [nvarchar](50) NOT NULL)

The Primary key(PersonId) of table Employee is also a forgein key(personid) of table Person

Next i added ado.net entity model in my application and create below service class on that

public class SomeServiceClass
{   
    public IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable(IEnumerable<int> employeesToCollect)
    {
        DemoIQueryableEntities db = new DemoIQueryableEntities();
        var allDetails = from Employee e in db.Employees
                         join Person p in db.People on e.PersonId equals p.PersonId
                         where employeesToCollect.Contains(e.PersonId)
                         select e;
        return allDetails;
    }

    public IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable(IEnumerable<int> employeesToCollect)
    {
        DemoIQueryableEntities db = new DemoIQueryableEntities();
        var allDetails = from Employee e in db.Employees
                         join Person p in db.People on e.PersonId equals p.PersonId
                         where employeesToCollect.Contains(e.PersonId)
                         select e;
        return allDetails;
    }
}

they contains same linq. It called in program.cs as defined below

class Program
{
    static void Main(string[] args)
    {
        SomeServiceClass s= new SomeServiceClass(); 

        var employeesToCollect= new []{0,1,2,3};

        //IQueryable execution part
        var IQueryableList = s.GetEmployeeAndPersonDetailIQueryable(employeesToCollect).Where(i => i.Gender=="M");            
        foreach (var emp in IQueryableList)
        {
            System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
        }
        System.Console.WriteLine("IQueryable contain {0} row in result set", IQueryableList.Count());

        //IEnumerable execution part
        var IEnumerableList = s.GetEmployeeAndPersonDetailIEnumerable(employeesToCollect).Where(i => i.Gender == "M");
        foreach (var emp in IEnumerableList)
        {
           System.Console.WriteLine("ID:{0}, EName:{1},Gender:{2}", emp.PersonId, emp.Person.FirstName, emp.Gender);
        }
        System.Console.WriteLine("IEnumerable contain {0} row in result set", IEnumerableList.Count());

        Console.ReadKey();
    }
}

The output is same for both obviously

ID:1, EName:Ken,Gender:M  
ID:3, EName:Roberto,Gender:M  
IQueryable contain 2 row in result set  
ID:1, EName:Ken,Gender:M  
ID:3, EName:Roberto,Gender:M  
IEnumerable contain 2 row in result set

So the question is what/where is the difference? It does not seem to have any difference right? Really!!

Let's have a look on sql queries generated and executed by entity framwork 5 during these period

IQueryable execution part

--IQueryableQuery1 
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])

--IQueryableQuery2
SELECT 
[GroupBy1].[A1] AS [C1]
FROM ( SELECT 
    COUNT(1) AS [A1]
    FROM [dbo].[Employee] AS [Extent1]
    WHERE ([Extent1].[PersonId] IN (0,1,2,3)) AND (N'M' = [Extent1].[Gender])
)  AS [GroupBy1]

IEnumerable execution part

--IEnumerableQuery1
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)

--IEnumerableQuery2
SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[Gender] AS [Gender]
FROM [dbo].[Employee] AS [Extent1]
WHERE [Extent1].[PersonId] IN (0,1,2,3)

Common script for both execution part

/* these two query will execute for both IQueryable or IEnumerable to get details from Person table
   Ignore these two queries here because it has nothing to do with IQueryable vs IEnumerable
--ICommonQuery1 
exec sp_executesql N'SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[FirstName] AS [FirstName], 
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=1

--ICommonQuery2
exec sp_executesql N'SELECT 
[Extent1].[PersonId] AS [PersonId], 
[Extent1].[FirstName] AS [FirstName], 
[Extent1].[LastName] AS [LastName]
FROM [dbo].[Person] AS [Extent1]
WHERE [Extent1].[PersonId] = @EntityKeyValue1',N'@EntityKeyValue1 int',@EntityKeyValue1=3
*/

So you have few questions now, let me guess those and try to answer them

Why are different scripts generated for same result?

Lets find out some points here,

all queries has one common part

WHERE [Extent1].[PersonId] IN (0,1,2,3)

why? Because both function IQueryable<Employee> GetEmployeeAndPersonDetailIQueryable and IEnumerable<Employee> GetEmployeeAndPersonDetailIEnumerable of SomeServiceClass contains one common line in linq queries

where employeesToCollect.Contains(e.PersonId)

Than why is the AND (N'M' = [Extent1].[Gender]) part is missing in IEnumerable execution part, while in both function calling we used Where(i => i.Gender == "M") inprogram.cs`

Now we are in the point where difference came between IQueryable and IEnumerable

What entity framwork does when an IQueryable method called, it tooks linq statement written inside the method and try to find out if more linq expressions are defined on the resultset, it then gathers all linq queries defined until the result need to fetch and constructs more appropriate sql query to execute.

It provide a lots of benefits like,

• only those rows populated by sql server which could be valid by the whole linq query execution
• helps sql server performance by not selecting unnecessary rows
• network cost get reduce

like here in example sql server returned to application only two rows after IQueryable execution` but returned THREE rows for IEnumerable query why?

In case of IEnumerable method, entity framework took linq statement written inside the method and constructs sql query when result need to fetch. it does not include rest linq part to constructs the sql query. Like here no filtering is done in sql server on column gender.

But the outputs are same? Because 'IEnumerable filters the result further in application level after retrieving result from sql server

SO, what should someone choose? I personally prefer to define function result as IQueryable<T> because there are lots of benefit it has over IEnumerable like, you could join two or more IQueryable functions, which generate more specific script to sql server.

Here in example you can see an IQueryable Query(IQueryableQuery2) generates a more specific script than IEnumerable query(IEnumerableQuery2) which is much more acceptable in my point of view.

i recommend use button inside LinearLayout for adjust to size of Linear.

I would have thought this would have been answered already - but surely what you want is this: box-shadow: 0 0 3px #CC0000;

Example: http://jsfiddle.net/vmzLW/

I think what you need is to use the event.currentTarget. This will contain the element that actually has the event listener. So if the whole <section> has the eventlistener event.target will be the clicked element, the <section> will be in event.currentTarget.

Otherwise parentNode might be what you're looking for.

I usually use Gloss library to serialize or deserialize JSON in iOS. For example, I have JSON that looks like this:

{"ABDC":[{"AB":"qwerty","CD":"uiop"}],[{"AB":"12334","CD":"asdf"}]}

First, I model the JSON array in Gloss struct:

Struct Struct_Name: Decodable {
   let IJ: String?
   let KL: String?
   init?(json: JSON){
       self.IJ = "AB" <~~ json
       self.KL = "CD" <~~ json
   }
}

And then in Alamofire responseJSON, I do this following thing:

Alamofire.request(url, method: .get, paramters: parametersURL).validate(contentType: ["application/json"]).responseJSON{ response in
 switch response.result{
   case .success (let data):
    guard let value = data as? JSON,
       let eventsArrayJSON = value["ABDC"] as? [JSON]
    else { fatalError() }
    let struct_name = [Struct_Name].from(jsonArray: eventsArrayJSON)//the JSON deserialization is done here, after this line you can do anything with your JSON
    for i in 0 ..< Int((struct_name?.count)!) {
       print((struct_name?[i].IJ!)!)
       print((struct_name?[i].KL!)!)
    }
    break

   case .failure(let error):
    print("Error: \(error)")
    break
 }
}

The output from the code above:

qwerty
uiop
1234
asdf

This may be irrelevant. It is for people don't want build the latest git on the host meanwhile they still can get the latest git.

I think most people don't like building the latest git on CentOS because the dependencies will contaminate the host and you have to run lots of commands. Therefore, I have an idea which is building git inside the Docker container and then install the executable via the docker volume mount. After that, you can delete the image and container.

Yes, the downside is you have to install docker. But the least dependencies are introduced to the host and you don't have to install other yum repo.

Here is my repository. https://github.com/wood1986/docker-library/tree/master/git

As simple as this !

var json_data = {"2013-01-21":1,"2013-01-22":7};

console.log(result);

Mathias Lin code working beautifully. However, you might want to consider changing this part inside drawPath method:

 if (lngLat.length >= 2 && gp1.getLatitudeE6() > 0 && gp1.getLongitudeE6() > 0
                    && gp2.getLatitudeE6() > 0 && gp2.getLongitudeE6() > 0) {

GeoPoint can be less than zero as well, I switch mine to:

     if (lngLat.length >= 2 && gp1.getLatitudeE6() != 0 && gp1.getLongitudeE6() != 0
                    && gp2.getLatitudeE6() != 0 && gp2.getLongitudeE6() != 0) {

Thank you :D

If you're using @ConfigurationProperties with Spring Boot 2 to inject maps with keys that contain colons then you need an additional level of escaping using square brackets inside the quotes because spring only allows alphanumeric and '-' characters, stripping out the rest. Your new key would look like this:

"[8.11.32.120:8000]": GoogleMapsKeyforThisDomain

See this github issue for reference.

You need to do something like this:

XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

You can convert hex to RGB:

string ccode = "#00FFFF00";
int argb = Int32.Parse(ccode.Replace("#", ""), NumberStyles.HexNumber);
Color clr = Color.FromArgb(argb);

Escape is set to \ by default, so you don't need to set it; but if you do, don't wrap it in quotes.

Ampersand is the SQL*Plus substitution variable marker; but you can change it, or more usefully in your case turn it off completely, with:

set define off

Then you don't need to bother escaping the value at all.

if (date1.getTime() > date2.getTime()) {
    alert("The first date is after the second date!");
}

Reference to Date object

Try this:

MessageBox.Show("Some text", "Some title", 
    MessageBoxButtons.OK, MessageBoxIcon.Error);

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

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

neRok touched on this answer above and I'm just expanding on it.

According to the slightly dated, but handy O'Reilly reference book, Javascript: The Definitive Guide:

The selectedIndex property of the Select object is an integer that specifies the index of the selected option within the Select object. If no option is selected, selectedIndex is -1.

As such, the following javascript code will "reset" the Select object to no options selected:

select_box = document.getElementById("myselectbox");
select_box.selectedIndex = -1;

Note that changing the selection in this way does not trigger the onchange() event handler.

I know this is old, but here is a one liner solution:

const hourDiff = start.diff(end, "hours");

Where start and end are moment objects.

Enjoy!

Django 1.10 no longer allows you to specify views as a string (e.g. 'myapp.views.home') in your URL patterns.

The solution is to update your urls.py to include the view callable. This means that you have to import the view in your urls.py. If your URL patterns don't have names, then now is a good time to add one, because reversing with the dotted python path no longer works.

from django.conf.urls import include, url

from django.contrib.auth.views import login
from myapp.views import home, contact

urlpatterns = [
    url(r'^$', home, name='home'),
    url(r'^contact/$', contact, name='contact'),
    url(r'^login/$', login, name='login'),
]

If there are many views, then importing them individually can be inconvenient. An alternative is to import the views module from your app.

from django.conf.urls import include, url

from django.contrib.auth import views as auth_views
from myapp import views as myapp_views

urlpatterns = [
    url(r'^$', myapp_views.home, name='home'),
    url(r'^contact/$', myapp_views.contact, name='contact'),
    url(r'^login/$', auth_views.login, name='login'),
]

Note that we have used as myapp_views and as auth_views, which allows us to import the views.py from multiple apps without them clashing.

See the Django URL dispatcher docs for more information about urlpatterns.

IIRC Code Behind is compiled serverside and javascript is interpreted client side. This means there is no direct link between the two.

What you can do on the other hand is have the client and server communicate through a nifty tool called AJAX. http://en.wikipedia.org/wiki/Asynchronous_JavaScript_and_XML

I got this problem today while installing SugarCRM (a free CRM).

The system was not able to connect to the database using the root user. I could definitively log in as root from the console... so what was the problem?

I found out that in my situation, I was getting exactly the same error, but that was because the password was sent to mysql directly from the $_POST data, in other words, the < character from my password was sent to mysql as < which means the password was wrong.

Everything else did not help a bit. The list of users in mysql were correct, including the anonymous user (which appears after the root entries.)

I think the core issue with Flask is that stdout gets buffered. I was able to print with print('Hi', flush=True). You can also disable buffering by setting the PYTHONUNBUFFERED environment variable (to any non-empty string).

Another possibility:

1. Create a UIButton in Interface builder.
2. Give it a type 'Custom'
3. Now, in IB it is possible to change the background color

However, the button is square, and that is not what we want. Create an IBOutlet with a reference to this button and add the following to the viewDidLoad method:

[buttonOutlet.layer setCornerRadius:7.0f];
[buttonOutlet.layer setClipToBounds:YES];

Don't forget to import QuartzCore.h

H2CO3 is right, you can use a makefile with the CXXFLAGS set with -std=c++11 A makefile is a simple text file with instructions about how to compile your program. Create a new file named Makefile (with a capital M). To automatically compile your code just type the make command in a terminal. You may have to install make.

Here's a simple one :

CXX=clang++
CXXFLAGS=-g -std=c++11 -Wall -pedantic
BIN=prog

SRC=$(wildcard *.cpp)
OBJ=$(SRC:%.cpp=%.o)

all: $(OBJ)
    $(CXX) -o $(BIN) $^

%.o: %.c
    $(CXX) $@ -c $<

clean:
    rm -f *.o
    rm $(BIN)

It assumes that all the .cpp files are in the same directory as the makefile. But you can easily tweak your makefile to support a src, include and build directories.

Edit : I modified the default c++ compiler, my version of g++ isn't up-to-date. With clang++ this makefile works fine.

<table id="myTable">
  <tbody>
    <tr>...</tr>
    <tr>...</tr>
  </tbody>
  <tr>...</tr>
</table>

Write with a javascript function

document.getElementById("myTable").insertRow(-1).innerHTML = '<tr>...</tr><tr>...</tr>';

No one else has used array_reduce yet, so thought I'd add this approach...

$find_by_uid = '100';
$is_in_array = array_reduce($userdb, function($carry, $user) use ($find_by_uid){
    return $carry ? $carry : $user['uid'] === $find_by_uid;
}); 
// Returns true

Gives you more fine control over the 'search' logic than array_search().

Note that I have used strict equality here but you could opt for different comparison logic. The $carry means the comparison needs to be true once, and the final result will be TRUE.

In modern browsers you do not need JQuery for this. Instead use

document.querySelectorAll('option:checked')

Or specify any DOM element instead of document

Found the way to do it nicely without creating your own layout on API >= 21.

It will only colorize texts and control drawables inside the action bar.

Hope it will be useful for someone.

I had the same issue and I resolved it by making changes in the UnityConfig.cs file In order to resolve the dependency issue in the UnityConfig.cs file you have to add:

public static void RegisterComponents()    
{
    var container = new UnityContainer();
    container.RegisterType<ITestService, TestService>();
    DependencyResolver.SetResolver(new UnityDependencyResolver(container));
}

It looks like you are trying to start the Python interpreter by running the command python.

However the interpreter is already started. It is interpreting python as a name of a variable, and that name is not defined.

Try this instead and you should hopefully see that your Python installation is working as expected:

print("Hello world!")

Date.parse recognizes only specific formats, and you don't have the option of telling it what your input format is. In this case it thinks that the input is in the format mm/dd/yyyy, so the result is wrong.

To fix this, you need either to parse the input yourself (e.g. with String.split) and then manually construct a Date object, or use a more full-featured library such as datejs.

Example for manual parsing:

var input = $('#' + controlName).val();
var parts = str.split("/");
var d1 = new Date(Number(parts[2]), Number(parts[1]) - 1, Number(parts[0]));

Example using date.js:

var input = $('#' + controlName).val();
var d1 = Date.parseExact(input, "d/M/yyyy");

I've never used it but Trilead, a free ISAPI filter which enables .htaccess based control, looks like what you want.

At my work we have our restful services on a different port number and the data resides in db2 on a pair of AS400s. We typically use the $.getJSON AJAX method because it easily returns JSONP using the ?callback=? without having any issues with CORS.

data ='USER=<?echo trim($USER)?>' +
         '&QRYTYPE=' + $("input[name=QRYTYPE]:checked").val();

        //Call the REST program/method returns: JSONP 
        $.getJSON( "http://www.stackoverflow.com/rest/resttest?callback=?",data)
        .done(function( json ) {        

              //  loading...
                if ($.trim(json.ERROR) != '') {
                    $("#error-msg").text(message).show();
                }
                else{
                    $(".error").hide();
                    $("#jsonp").text(json.whatever);

                }

        })  
        .fail(function( jqXHR, textStatus, error ) {
        var err = textStatus + ", " + error;
        alert('Unable to Connect to Server.\n Try again Later.\n Request Failed: ' + err);
        });     

For me, the below helped

Find org.apache.http.legacy.jar which is in Android/Sdk/platforms/android-23/optional, add it to your dependency.

There is even a better way to create a Map along with initialization:

Map<String, String> rightHereMap = new HashMap<String, String>()
{
    {
        put("key1", "value1");
        put("key2", "value2");
    }
};

For more options take a look here How can I initialise a static Map?

If I understand correctly, you want to know how to convert bytes encoded as a hex string to its form as an ASCII text, like "537461636B" would be converted to "Stack", in such case then the following code should solve your problem.

Have not run any benchmarks but I assume it is not the peak of efficiency.

static char ByteToAscii(const char *input) {
  char singleChar, out;
  memcpy(&singleChar, input, 2);
  sprintf(&out, "%c", (int)strtol(&singleChar, NULL, 16));
  return out;
}

int HexStringToAscii(const char *input, unsigned int length,
                            char **output) {
  int mIndex, sIndex = 0;
  char buffer[length];
  for (mIndex = 0; mIndex < length; mIndex++) {
    sIndex = mIndex * 2;
    char b = ByteToAscii(&input[sIndex]);
    memcpy(&buffer[mIndex], &b, 1);
  }
  *output = strdup(buffer);
  return 0;
}

# -*- coding: utf-8 -*- is a Python 2 thing. In Python 3+, the default encoding of source files is already UTF-8 and that line is useless.

See: Should I use encoding declaration in Python 3?

pyupgrade is a tool you can run on your code to remove those comments and other no-longer-useful leftovers from Python 2, like having all your classes inherit from object.

In additional to the popular K8s, jasypt or vault solutions, there's also Karmahostage. It enables you to do:

@EncryptedValue("${application.secret}")
private String application;

It works the same way jasypt does, but encryption happens on a dedicated saas solution, with a more fine-grained ACL model attached to it.

I've found a temporary solution that will at least let me process this job. I wrote a short AutoIt script that waits for the "Update Links" window to appear, then clicks the "Don't Update" button. Code is as follows:

while 1
if winexists("Microsoft Excel","This workbook contains links to other data sources.") Then
   controlclick("Microsoft Excel","This workbook contains links to other data sources.",2)
EndIf
WEnd

So far this seems to be working. I'd really like to find a solution that's entirely VBA, however, so that I can make this a standalone application.

I'm going to make a couple of assumptions in my answer. I'm assuming your data starts in A1 and there are no empty cells in the first column of each row that has data.

This code will:

1. Find the last row in column A that has data
2. Loop through each row
3. Find the last column in current row with data
4. Loop through each cell in current row up to last column found.

This is not a fast method but will iterate through each one individually as you suggested is your intention.

Sub iterateThroughAll()
    ScreenUpdating = False
    Dim wks As Worksheet
    Set wks = ActiveSheet

    Dim rowRange As Range
    Dim colRange As Range

    Dim LastCol As Long
    Dim LastRow As Long
    LastRow = wks.Cells(wks.Rows.Count, "A").End(xlUp).Row

    Set rowRange = wks.Range("A1:A" & LastRow)

    'Loop through each row
    For Each rrow In rowRange
        'Find Last column in current row
        LastCol = wks.Cells(rrow, wks.Columns.Count).End(xlToLeft).Column
        Set colRange = wks.Range(wks.Cells(rrow, 1), wks.Cells(rrow, LastCol))

        'Loop through all cells in row up to last col
        For Each cell In colRange
            'Do something to each cell
            Debug.Print (cell.Value)
        Next cell
    Next rrow
    ScreenUpdating = True
End Sub

t = (1,2,3,4,5)

t= t + (6,7)

output :

(1,2,3,4,5,6,7)

deleted the c#... here is the vb.net

<%=Html.ActionLink("Home", "Index", "Home", New With {.class = "tab"}, Nothing)%>

What you want is the following:

SELECT DISTINCT * FROM posted WHERE ad='$key' GROUP BY link ORDER BY day, month

if there are 4 rows for example where link is the same, it will pick only one (I asume the first one).

I went through all the previous answers (and answers to similar questions) without success, so here is what finally worked for me. The key step was to explicitly grant privileges on the mysql server to a local user (for the server), but with my local IP appended to it (myuser@*.*.*.*). The complete step by step solution is as follows:

1. Comment out the bind_address line in /etc/mysql/my.cnf at the server (i.e. the EC2 Instance). I suppose bind_address=0.0.0.0 would also work, but it's not needed as others have mentioned.

2. Add a rule (as others have mentioned too) for MYSQL to the EC2 instance's security group with port 3306 and either My IP or Anywhere as Source. Both work fine after following all the steps.

3. Create a new user myuser with limited privileges to one particular database mydb (basically following the instructions in this Amazon tutorial):

   $EC2prompt> mysql -u root -p
   [...omitted output...]
   mysql>  CREATE USER 'myuser'@'localhost' IDENTIFIED BY 'your_strong_password';
   mysql>  GRANT ALL PRIVILEGES ON 'mydb'.* TO 'myuser'@'localhost';`
   

4. Here's the key step, without which my local address was refused when attempting a remote connection (ERROR 1130 (HY000): Host '*.*.*.23' is not allowed to connect to this MySQL server):

   mysql> GRANT ALL PRIVILEGES ON 'mydb'.* TO 'myuser'@'*.*.*.23';
   mysql> FLUSH PRIVILEGES;`
   

   (replace '*.*.*.23' by your local IP address)

5. For good measure, I exited mysql to the shell and restarted the msyql server:

   $EC2prompt> sudo service mysql restart

6. After these steps, I was able to happily connect from my computer with:

   $localprompt> mysql -h myinstancename.amazonaws.com -P 3306 -u myuser -p

   (replace myinstancename.amazonaws.com by the public address of your EC2 instance)

There is one more explanation for this Connection Refused problem, that I missed from answers above. In my case I had thread running (quartz scheduler) started from context listener (in contextInitialized), never to be stopped (like in contextDestroyed).

This in turn caused the server port associated to be closed, where as the container kept on running (hence: connection refused on the server port).

I fixed it stopping quartz in contextDestroyed and I didn't experience this issue ever since.

See here for similar issues: Tomcat doesn't stop. How can I debug this?

mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;

These are deprecated use the following..

 // Connects to your Database
            $link = mysqli_connect("localhost", "root", "", "");

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)
VALUES ('$filename')" ;

I always put my scripts in the header. My reasons:

1. I like to separate code and (static) text
2. I usually load my script from external sources
3. The same script is used from several pages, so it feels like an include file (which also goes in the header)

Here's another way to go about it:

$stdout = fopen('php://stdout', 'w');
fwrite($stdout, 'Hello, World!' . PHP_EOL);

The PHP_EOL adds new line.

awk -F"|" '{gsub(/\"/,"|");print "\""$2"\""}' your_file

You can use this code to see the last modified date of a file.

DateTime dt = File.GetLastWriteTime(path);

And this code to see the creation time.

DateTime fileCreatedDate = File.GetCreationTime(@"C:\Example\MyTest.txt");

FQDN/auth/realms/{realm_name}/.well-known/openid-configuration

you will see everything here, plus if the identity provider is also Keycloak then feeding this URL will setup everything also true with other identity providers if they support and they already handled it

This best solution if you are using angular uib-bootsrap is to Use dependency injection for $uibTooltipProvider, you can change the way tooltips and popovers behave by default for all the tooltips.

$uibTooltipProvider.options({
  appendToBody: true
});

$uibTooltipProvider Through the $uibTooltipProvider, you can change the way tooltips and popovers behave by default; the attributes above always take precedence. The following methods are available:

setTriggers(obj) (Example: { 'openTrigger': 'closeTrigger' }) - Extends the default trigger mappings mentioned above with mappings of your own.

options(obj) - Provide a set of defaults for certain tooltip and popover attributes. Currently supports the ones with the C badge.

For 2 and more left joins (left joining creatorUser and initiatorUser )

IQueryable<CreateRequestModel> queryResult = from r in authContext.Requests
                                             join candidateUser in authContext.AuthUsers
                                             on r.CandidateId equals candidateUser.Id

                                             from x1 in init.DefaultIfEmpty()

                                             where candidateUser.UserName.Equals(candidateUsername)
                                             select new CreateRequestModel
                                             {
                                                 UserName = candidateUser.UserName,
                                                 CreatorId = (x == null ? String.Empty : x.UserName),
                                                 InitiatorId = (x1 == null ? String.Empty : x1.UserName),
                                                 CandidateId = candidateUser.UserName
                                             };

You need to add the jar file in the classpath. To compile your java class:

javac -cp .;jwitter.jar MyClass.java

To run your code (provided that MyClass contains a main method):

java -cp .;jwitter.jar MyClass

You can have the jar file anywhere. The above work if the jar file is in the same directory as your java file.

You can use HttpParams from @angular/common/http and pass a string with the query. For example:

import { HttpClient, HttpParams } from '@angular/common/http';
const query = 'key=value' // date=2020-03-06

const options = {
  params: new HttpParams({
    fromString: query
  })
}

Now in your code

this.http.get(urlFull, options);

And this works for you :)

Installing Yarn for Ubuntu 16.04 (not sure if this will be the same as 14.04 as it's slightly different than zappee's answer for 17.04)

ll.addView(btn);

The metacharacter \b is an anchor like the caret and the dollar sign. It matches at a position that is called a "word boundary". This match is zero-length.

There are three different positions that qualify as word boundaries:

• Before the first character in the string, if the first character is a word character.
• After the last character in the string, if the last character is a word character.
• Between two characters in the string, where one is a word character and the other is not a word character.

\B is the negated version of \b. \B matches at every position where \b does not. Effectively, \B matches at any position between two word characters as well as at any position between two non-word characters.

First, Identify the user you are logged in as:

 select user();
 select current_user();

The result for the first command is what you attempted to login as, the second is what you actually connected as. Confirm that you are logged in as root@localhost in mysql.

Grant_priv to root@localhost. Here is how you can check.

mysql> SELECT host,user,password,Grant_priv,Super_priv FROM mysql.user;
+-----------+------------------+-------------------------------------------+------------+------------+
| host      | user             | password                                  | Grant_priv | Super_priv |
+-----------+------------------+-------------------------------------------+------------+------------+
| localhost | root             | ***************************************** | N          | Y          |
| localhost | debian-sys-maint | ***************************************** | Y          | Y          |
| localhost | staging          | ***************************************** | N          | N          |

You can see that the Grant_priv is set to N for root@localhost. This needs to be Y. Below is how to fixed this:

UPDATE mysql.user SET Grant_priv='Y', Super_priv='Y' WHERE User='root';
FLUSH PRIVILEGES;
GRANT ALL ON *.* TO 'root'@'localhost';

I logged back in, it was fine.

Create php.ini file with your desired setting and upload it in your root folder of server. It will take effect with this new setting.

You can't edit the php.ini file of godaddy server, but you can upload your own copy of your php.ini with your new setting.

This new setting will be available only to you. Other websites will not be affected with this new setting.

Previously I faced the same issue, but after doing this my problem was resolved.

If it's truly a word, bar that you don't want to match, then:

^(?!.*\bbar\b).*$

The above will match any string that does not contain bar that is on a word boundary, that is to say, separated from non-word characters. However, the period/dot (.) used in the above pattern will not match newline characters unless the correct regex flag is used:

^(?s)(?!.*\bbar\b).*$

Alternatively:

^(?!.*\bbar\b)[\s\S]*$

Instead of using any special flag, we are looking for any character that is either white space or non-white space. That should cover every character.

But what if we would like to match words that might contain bar, but just not the specific word bar?

(?!\bbar\b)\b\[A-Za-z-]*bar[a-z-]*\b

1. (?!\bbar\b) Assert that the next input is not bar on a word boundary.
2. \b\[A-Za-z-]*bar[a-z-]*\b Matches any word on a word boundary that contains bar.

See Regex Demo

In the visual studio community edition 2017, sometimes the selection of Supported ABIs from Android Options wont work.

In that case please verify that the .csproj has the following line and no duplicate lines in the same build configurations.

 <AndroidSupportedAbis>armeabi;armeabi-v7a;x86;x86_64;arm64-v8a</AndroidSupportedAbis>

In order to edit,

1. Unload your Android Project
2. Right click and select Edit Project ...
3. Make sure you have the above line only one time in a build configuration
4. Save
5. Right click on your android project and Reload

For Swift 3 you can use the following:

 func setupSpinner(){
    spinner = UIActivityIndicatorView(frame: CGRect(x: 0, y: 0, width: 40, height:40))
    spinner.color = UIColor(Colors.Accent)
    self.spinner.center = CGPoint(x:UIScreen.main.bounds.size.width / 2, y:UIScreen.main.bounds.size.height / 2)
    self.view.addSubview(spinner)
    spinner.hidesWhenStopped = true
}

Defining ‘Midnight’

The word “midnight” is tricky to define.

Some think of it as the moment before a new day starts. Trying to represent that in software as tricky as the last moment of the day can always be subdivided as a smaller fraction of a second.

I suggest a better way of thinking about this is to get “first moment of the day”.

This supports the commonly used approach of defining a span of time as ‘Half-Open’, where the beginning is inclusive while the ending is exclusive. So a full day starts with the first moment of the day and runs up to, but not including, the first moment of the following day. A full day would like this (notice the date going from the 3rd to the 4th):

2016-02-03T00:00:00.0-08:00[America/Los_Angeles]/2016-02-04T00:00:00.0-08:00[America/Los_Angeles]

Joda-Time

If using the Joda-Time library, call withTimeAtStartOfDay.

Note how we specify the time zone. If omitted, the JVM’s current default time zone is implicitly applied. Better to be explicit.

DateTime todayStart = DateTime.now( DateTimeZone.forID( "America/Montreal" ) ).withTimeAtStartOfDay() ;

If using Java 8 or later, better to use the java.time package built into Java. See sibling Answer by Jens Hoffman.

You can use a dynamic array when you don't know the number of values it will contain until run-time:

Dim Zombies() As Integer
ReDim Zombies(NumberOfZombies)

Or you could do everything with one statement if you're creating an array that's local to a procedure:

ReDim Zombies(NumberOfZombies) As Integer

Fixed-size arrays require the number of elements contained to be known at compile-time. This is why you can't use a variable to set the size of the array—by definition, the values of a variable are variable and only known at run-time.

You could use a constant if you knew the value of the variable was not going to change:

Const NumberOfZombies = 2000

but there's no way to cast between constants and variables. They have distinctly different meanings.

Ruby 2.5+

As of Ruby 2.5 you can use delete_prefix or delete_prefix! to achieve this in a readable manner.

In this case "[12,23,987,43".delete_prefix("[").

More info here:

• Official docs

• https://blog.jetbrains.com/ruby/2017/10/10-new-features-in-ruby-2-5/

• https://bugs.ruby-lang.org/issues/12694

'invisible'.delete_prefix('in') #=> "visible"
'pink'.delete_prefix('in') #=> "pink"

N.B. you can also use this to remove items from the end of a string with delete_suffix and delete_suffix!

'worked'.delete_suffix('ed') #=> "work"
'medical'.delete_suffix('ed') #=> "medical"

• Docs
• https://bugs.ruby-lang.org/issues/13665

Edit:

Using the Tin Man's benchmark setup, it looks pretty quick too (under the last two entries delete_p and delete_p!). Doesn't quite pip the previous faves for speed, though is very readable.

Yes it is possible using ProcessBuilder.

ProcessBuilder example:

import java.io.*;
import java.util.*;

public class CmdProcessBuilder {
  public static void main(String args[]) 
     throws InterruptedException,IOException 
  {
    List<String> command = new ArrayList<String>();
    command.add(args[0]);


    ProcessBuilder builder = new ProcessBuilder(command);
    Map<String, String> environ = builder.environment();

    final Process process = builder.start();
    InputStream is = process.getInputStream();
    InputStreamReader isr = new InputStreamReader(is);
    BufferedReader br = new BufferedReader(isr);
    String line;
    while ((line = br.readLine()) != null) {
      System.out.println(line);
    }
    System.out.println("Program terminated!");
  }
}

Check these examples:

http://www.rgagnon.com/javadetails/java-0014.html

http://www.java-tips.org/java-se-tips/java.util/from-runtime.exec-to-processbuilder.html

Yes, it's possible. But first read, "What happens when I change my username?"

To change your username, click your profile picture in the top right corner, then click Settings. On the left side, click Account. Then click Change username.

You have a column InvoiceID in the Invoices table and also in the InvoiceLineItems table. There is no way for the query execution engine to know which one you want returned.

Adding a table alias will help:

SELECT V.VendorName, I.InvoiceID, IL.InvoiceSequence, IL.InvoiceLineItemAmount
FROM Vendors V
JOIN Invoices I ON (...)
JOIN InvoiceLineItems IL ON (...)
WHERE ...
ORDER BY V.VendorName, I.InvoiceID, IL.InvoiceSequence, IL.InvoiceLineItemAmount

According to the certification exam you should use Convert.ToXXX() whenever possible for simple conversions because it optimizes performance better than CXXX conversions.

The ISO C++ standard way to do it is to #include <iomanip> and use io manipulators like std::setw. However, that said, those io manipulators are a real pain to use even for text, and are just about unusable for formatting numbers (I assume you want your dollar amounts to line up on the decimal, have the correct number of significant digits, etc.). Even for just plain text labels, the code will look something like this for the first part of your first line:

// using standard iomanip facilities
cout << setw(20) << "Artist"
     << setw(20) << "Title"
     << setw(8) << "Price";
// ... not going to try to write the numeric formatting...

If you are able to use the Boost libraries, run (don't walk) and use the Boost.Format library instead. It is fully compatible with the standard iostreams, and it gives you all the goodness for easy formatting with printf/Posix formatting string, but without losing any of the power and convenience of iostreams themselves. For example, the first parts of your first two lines would look something like:

// using Boost.Format
cout << format("%-20s %-20s %-8s\n")  % "Artist" % "Title" % "Price";
cout << format("%-20s %-20s %8.2f\n") % "Merle" % "Blue" % 12.99;

I agree with Cat Plus Plus's answer. However, if you know this will only be used on Unix-like OSes, you can use external calls to the shell commands mkdir, chmod, and chown. Make sure to pass extra flags to recursively affect directories:

>>> import subprocess
>>> subprocess.check_output(['mkdir', '-p', 'first/second/third']) 
# Equivalent to running 'mkdir -p first/second/third' in a shell (which creates
# parent directories if they do not yet exist).

>>> subprocess.check_output(['chown', '-R', 'dail:users', 'first'])
# Recursively change owner to 'dail' and group to 'users' for 'first' and all of
# its subdirectories.

>>> subprocess.check_output(['chmod', '-R', 'g+w', 'first'])
# Add group write permissions to 'first' and all of its subdirectories.

EDIT I originally used commands, which was a bad choice since it is deprecated and vulnerable to injection attacks. (For example, if a user gave input to create a directory called first/;rm -rf --no-preserve-root /;, one could potentially delete all directories).

EDIT 2 If you are using Python less than 2.7, use check_call instead of check_output. See the subprocess documentation for details.

pip install mechanize

mechanize supports only python 2.

For python3 refer https://stackoverflow.com/a/31774959/4773973 for alternatives.

map function in python can be used. It takes two arguments. First argument is the function which has to be used for each element of the list. Second argument is the iterable.

a = [1, 2, 3]   
map(str, a)  
['1', '2', '3']

After converting the list into string you can use simple join function to combine list into a single string

a = map(str, a)    
''.join(a)      
'123'

We have an app in Google Play and the App Store that will scan barcodes into a web site. The app is called Scan to Web. http://berrywing.com/scantoweb.html

You can even embed a link or button to start the scanner yourself within your web page.

<a href="bwstw://startscanner">Link to start scanner</a>

The developer documentation website for the app covers how to use the app and use JavaScript for processing the barcode scan. http://berrywing.com/scantoweb/#htmlscanbutton

I have a simple solution on handling home button press. Here is my code, it can be useful:

public class LifeCycleActivity extends Activity {


boolean activitySwitchFlag = false;

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) 
{
    if(keyCode == KeyEvent.KEYCODE_BACK)
    {
        activitySwitchFlag = true;
        // activity switch stuff..
        return true;
    }
    return false;
}

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}

@Override 
public void onPause(){
    super.onPause();
    Log.v("TAG", "onPause" );
    if(activitySwitchFlag)
        Log.v("TAG", "activity switch");
    else
        Log.v("TAG", "home button");
    activitySwitchFlag = false;
}

public void gotoNext(View view){
    activitySwitchFlag = true;
    startActivity(new Intent(LifeCycleActivity.this, NextActivity.class));
}

}

As a summary, put a boolean in the activity, when activity switch occurs(startactivity event), set the variable and in onpause event check this variable..

Since you already have sent some data,

System.out.println("going to demo.jsp");

you won't be able to send a redirect.

EDIT : It is not bleeding edge anymore : http://blog.docker.com/2016/02/docker-1-10/

Original Answer
I battled with it the whole night. If you're not afraid of bleeding edge, the latest version of Docker engine and Docker compose both implement libnetwork.

With the right config file (that need to be put in version 2), you will create services that will all see each other. And, bonus, you can scale them with docker-compose as well (you can scale any service you want that doesn't bind port on the host)

Here is an example file

version: "2"
services:
  router:
    build: services/router/
    ports:
      - "8080:8080"
  auth:
    build: services/auth/
  todo:
    build: services/todo/
  data:
    build: services/data/

And the reference for this new version of compose file: https://github.com/docker/compose/blob/1.6.0-rc1/docs/networking.md

Django 1.10+

Use an attribute, not a method:

if request.user.is_authenticated: # <-  no parentheses any more!
    # do something if the user is authenticated

The use of the method of the same name is deprecated in Django 2.0, and is no longer mentioned in the Django documentation.

return HttpResponse(json.dumps({
    "is_authenticated": request.user.is_authenticated()
}), content_type='application/json') 

that after updated to the property request.user.is_authenticated was throwing the exception TypeError: Object of type 'CallableBool' is not JSON serializable. The solution was to use JsonResponse, which could handle the CallableBool object properly when serializing:

return JsonResponse({
    "is_authenticated": request.user.is_authenticated
})

If you can't rely on getting your IP address from a DNS server (which has happened to me), you can use the following approach:

The System.Net.NetworkInformation namespace contains a NetworkInterface class, which has a static GetAllNetworkInterfaces method.

This method will return all "network interfaces" on your machine, and there are generally quite a few, even if you only have a wireless adapter and/or an ethernet adapter hardware installed on your machine. All of these network interfaces have valid IP addresses for your local machine, although you probably only want one.

If you're looking for one IP address, then you'll need to filter the list down until you can identify the right address. You will probably need to do some experimentation, but I had success with the following approach:

• Filter out any NetworkInterfaces that are inactive by checking for OperationalStatus == OperationalStatus.Up. This will exclude your physical ethernet adapter, for instance, if you don't have a network cable plugged in.

For each NetworkInterface, you can get an IPInterfaceProperties object using the GetIPProperties method, and from an IPInterfaceProperties object you can access the UnicastAddresses property for a list of UnicastIPAddressInformation objects.

• Filter out non-preferred unicast addresses by checking for DuplicateAddressDetectionState == DuplicateAddressDetectionState.Preferred
• Filter out "virtual" addresses by checking for AddressPreferredLifetime != UInt32.MaxValue.

At this point I take the address of the first (if any) unicast address that matches all of these filters.

EDIT:

[revised code on May 16, 2018 to include the conditions mentioned in the text above for duplicate address detection state and preferred lifetime]

The sample below demonstrates filtering based on operational status, address family, excluding the loopback address (127.0.0.1), duplicate address detection state, and preferred lifetime.

static IEnumerable<IPAddress> GetLocalIpAddresses()
{
    // Get the list of network interfaces for the local computer.
    var adapters = NetworkInterface.GetAllNetworkInterfaces();

    // Return the list of local IPv4 addresses excluding the local
    // host, disconnected, and virtual addresses.
    return (from adapter in adapters
            let properties = adapter.GetIPProperties()
            from address in properties.UnicastAddresses
            where adapter.OperationalStatus == OperationalStatus.Up &&
                  address.Address.AddressFamily == AddressFamily.InterNetwork &&
                  !address.Equals(IPAddress.Loopback) &&
                  address.DuplicateAddressDetectionState == DuplicateAddressDetectionState.Preferred &&
                  address.AddressPreferredLifetime != UInt32.MaxValue
            select address.Address);
}

if your springfox version higher than 2.5, should be add WebSecurityConfiguration as below:

@Override
public void configure(HttpSecurity http) throws Exception {
    // TODO Auto-generated method stub
    http.authorizeRequests()
        .antMatchers("/v2/api-docs", "/swagger-resources/configuration/ui", "/swagger-resources", "/swagger-resources/configuration/security", "/swagger-ui.html", "/webjars/**").permitAll()
        .and()
        .authorizeRequests()
        .anyRequest()
        .authenticated()
        .and()
        .csrf().disable();
}

I recommend the following syntax for readability.

<? if ($condition): ?>
  <p>Content</p>
<? elseif ($other_condition): ?>
  <p>Other Content</p>
<? else: ?>
  <p>Default Content</p>
<? endif; ?>

Note, omitting php on the open tags does require that short_open_tags is enabled in your configuration, which is the default. The relevant curly-brace-free conditional syntax is always enabled and can be used regardless of this directive.

This code will do what you're looking for. It's based on examples found here and here.

The autofmt_xdate() call is particularly useful for making the x-axis labels readable.

import numpy as np
from matplotlib import pyplot as plt

fig = plt.figure()

width = .35
ind = np.arange(len(OY))
plt.bar(ind, OY, width=width)
plt.xticks(ind + width / 2, OX)

fig.autofmt_xdate()

plt.savefig("figure.pdf")

I did it! Using <intent-filter>. Put the following into your manifest file:

<intent-filter>
  <action android:name="android.intent.action.VIEW" />
  <category android:name="android.intent.category.DEFAULT" />
  <category android:name="android.intent.category.BROWSABLE" />
  <data android:host="www.youtube.com" android:scheme="http" />
</intent-filter>

This works perfectly!

You could do something like this if you wanted

package main

import "fmt"

type Pair struct {
    a, b interface{}
}

func main() {
    p1 := Pair{"finished", 42}
    p2 := Pair{6.1, "hello"}
    fmt.Println("p1=", p1, "p2=", p2)
    fmt.Println("p1.b", p1.b)
    // But to use the values you'll need a type assertion
    s := p1.a.(string) + " now"
    fmt.Println("p1.a", s)
}

However I think what you have already is perfectly idiomatic and the struct describes your data perfectly which is a big advantage over using plain tuples.

Using __doPostBack directly is sooooo the 2000s. Anybody coding WebForms in 2018 uses GetPostBackEventReference

(More seriously though, adding this as an answer for completeness. Using the __doPostBack directly is bad practice (single underscore prefix typically indicates a private member and double indicates a more universal private member), though it probably won't change or become obsolete at this point. We have a fully supported mechanism in ClientScriptManager.GetPostBackEventReference.)

Assuming your btnRefresh is inside our UpdatePanel and causes a postback, you can use GetPostBackEventReference like this (inspiration):

function RefreshGrid() {
    <%= ClientScript.GetPostBackEventReference(btnRefresh, String.Empty) %>;
}

I usually store phone numbers as a BIGINT in E164 format.

E164 never start with a 0, with the first few digits being the country code.

+441234567890
+44 (0)1234 567890
01234 567890

etc. would be stored as 441234567890.

Requesting Permissions In the following code, we will ask for camera permission:

in java

EasyPermissions is a wrapper library to simplify basic system permissions logic when targeting Android M or higher.

Installation EasyPermissions is installed by adding the following dependency to your build.gradle file:

dependencies {

    // For developers using AndroidX in their applications
    implementation 'pub.devrel:easypermissions:3.0.0'

    // For developers using the Android Support Library
    implementation 'pub.devrel:easypermissions:2.0.1'

}


private void askAboutCamera(){

        EasyPermissions.requestPermissions(
                this,
                "A partir deste ponto a permissão de câmera é necessária.",
                CAMERA_REQUEST_CODE,
                Manifest.permission.CAMERA );
}

I know this is a very old question, yes, I agree we can not hide address bar in modern browsers, but we can hide the url in address bar (e.g show url about:blank), following is my work around solution.

var iframe = '<html><head><style>body, html {width: 100%; height: 100%; margin: 0; padding: 0}</style></head><body><iframe src="https://www.w3schools.com" style="height:calc(100% - 4px);width:calc(100% - 4px)"></iframe></html></body>';

var win = window.open("","","width=600,height=480,toolbar=no,menubar=no,resizable=yes");
win.document.write(iframe);

The best way to implement a RESTful search is to consider the search itself to be a resource. Then you can use the POST verb because you are creating a search. You do not have to literally create something in a database in order to use a POST.

For example:

Accept: application/json
Content-Type: application/json
POST http://example.com/people/searches
{
  "terms": {
    "ssn": "123456789"
  },
  "order": { ... },
  ...
}

You are creating a search from the user's standpoint. The implementation details of this are irrelevant. Some RESTful APIs may not even need persistence. That is an implementation detail.

You can find what is the php.ini file used:

• By add phpinfo() in a php page and display the page (like the picture under)
• From the shell, enter: php -i

Next, you can find the information in the Loaded Configuration file (so here it's /user/local/etc/php/php.ini)

Sometimes, you have indicated (none), in this case you just have to put your custom php.ini that you can find here: http://git.php.net/?p=php-src.git;a=blob;f=php.ini-production;hb=HEAD

I hope this answer will help.

The for attribute is called htmlFor for consistency with the DOM property API. If you're using the development build of React, you should have seen a warning in your console about this.

cat foo.txt | strings -n 8 > bar.txt

will do the job.

There's no mystery here, the linker is telling you that you haven't defined the missing symbols, and you haven't.

Similarity::Similarity() or Similarity::~Similarity() are just missing and you have defined the others incorrectly,

void Similarity::readData(Scanner& inStream){
}

not

void readData(Scanner& inStream){
}

etc. etc.

The second one is a function called readData, only the first is the readData method of the Similarity class.

To be clear about this, in Similarity.h

void readData(Scanner& inStream);

but in Similarity.cpp

void Similarity::readData(Scanner& inStream){
}

You probably don't even need string substitution for that. If your original string is JSON, try:

js> a="['abc','xyz']"
['abc','xyz']
js> eval(a).join(",")
abc,xyz

Be careful with eval, of course.

Use the below code to save the image to internal directory.

private String saveToInternalStorage(Bitmap bitmapImage){
        ContextWrapper cw = new ContextWrapper(getApplicationContext());
         // path to /data/data/yourapp/app_data/imageDir
        File directory = cw.getDir("imageDir", Context.MODE_PRIVATE);
        // Create imageDir
        File mypath=new File(directory,"profile.jpg");

        FileOutputStream fos = null;
        try {           
            fos = new FileOutputStream(mypath);
       // Use the compress method on the BitMap object to write image to the OutputStream
            bitmapImage.compress(Bitmap.CompressFormat.PNG, 100, fos);
        } catch (Exception e) {
              e.printStackTrace();
        } finally {
            try {
              fos.close();
            } catch (IOException e) {
              e.printStackTrace();
            }
        } 
        return directory.getAbsolutePath();
    }

Explanation :

1.The Directory will be created with the given name. Javadocs is for to tell where exactly it will create the directory.

2.You will have to give the image name by which you want to save it.

To Read the file from internal memory. Use below code

private void loadImageFromStorage(String path)
{

    try {
        File f=new File(path, "profile.jpg");
        Bitmap b = BitmapFactory.decodeStream(new FileInputStream(f));
            ImageView img=(ImageView)findViewById(R.id.imgPicker);
        img.setImageBitmap(b);
    } 
    catch (FileNotFoundException e) 
    {
        e.printStackTrace();
    }

}

points is not within the function's scope. You can grab a reference to the variable by using nonlocal:

points = 0
def test():
    nonlocal points
    points += 1

If points inside test() should refer to the outermost (module) scope, use global:

points = 0
def test():
    global points
    points += 1

I know this is old but you could create a custom extension if you needed to create that form over and over:

public static MvcForm BeginMultipartForm(this HtmlHelper htmlHelper)
{
    return htmlHelper.BeginForm(null, null, FormMethod.Post, 
     new Dictionary<string, object>() { { "enctype", "multipart/form-data" } });
}

Usage then just becomes

<% using(Html.BeginMultipartForm()) { %>

To add to the above, the most obvious place to add stylesheet_link_tag is in your global application layout - application.html.erb.

If you just store the data in a database as you would if you were manually putting it into an array

"INSERT INTO database_name.database_table (`array`)
    VALUES
    ('One,Two,Three,Four')";

Then when you are pulling from the database, use the explode() function

$sql = mysql_query("SELECT * FROM database_name.database_table");
$numrows = mysql_num_rows($sql);
if($numrows != 0){
    while($rows = mysql_fetch_assoc($sql)){
        $array_from_db = $rows['array'];
    }
}else{
    echo "No rows found!".mysql_error();
}
$array = explode(",",$array_from_db);
foreach($array as $varchar){
    echo $varchar."<br/>";
}

Like so!

For a long time, CMake had the add_definitions command for this purpose. However, recently the command has been superseded by a more fine grained approach (separate commands for compile definitions, include directories, and compiler options).

An example using the new add_compile_definitions:

add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION})
add_compile_definitions(WITH_OPENCV2)

Or:

add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION} WITH_OPENCV2)

The good part about this is that it circumvents the shabby trickery CMake has in place for add_definitions. CMake is such a shabby system, but they are finally finding some sanity.

Find more explanation on which commands to use for compiler flags here: https://cmake.org/cmake/help/latest/command/add_definitions.html

Likewise, you can do this per-target as explained in Jim Hunziker's answer.

I have tried setting the heap size upto 2200M on 32bit Linux machine and JVM worked fine. The JVM didnt start when I set it to 2300M.

One of the most possible causes of this error could be that you have defined older version in your package.json. To solve this problem, change the versions in the package.json to match those npm is complaining about.

Once done, run npm install and voila!!.

Here I found this article which is send post request using JsonConvert.SerializeObject() & StringContent() to HttpClient.PostAsync data

static async Task Main(string[] args)
{
    var person = new Person();
    person.Name = "John Doe";
    person.Occupation = "gardener";

    var json = Newtonsoft.Json.JsonConvert.SerializeObject(person);
    var data = new System.Net.Http.StringContent(json, Encoding.UTF8, "application/json");

    var url = "https://httpbin.org/post";
    using var client = new HttpClient();

    var response = await client.PostAsync(url, data);

    string result = response.Content.ReadAsStringAsync().Result;
    Console.WriteLine(result);
}

ng-bind-html-unsafe only renders the content as HTML. It doesn't bind Angular scope to the resulted DOM. You have to use $compile service for that purpose. I created this plunker to demonstrate how to use $compile to create a directive rendering dynamic HTML entered by users and binding to the controller's scope. The source is posted below.

demo.html

<!DOCTYPE html>
<html ng-app="app">

  <head>
    <script data-require="[email protected]" data-semver="1.0.7" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.js"></script>
    <script src="script.js"></script>
  </head>

  <body>
    <h1>Compile dynamic HTML</h1>
    <div ng-controller="MyController">
      <textarea ng-model="html"></textarea>
      <div dynamic="html"></div>
    </div>
  </body>

</html>

script.js

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

app.directive('dynamic', function ($compile) {
  return {
    restrict: 'A',
    replace: true,
    link: function (scope, ele, attrs) {
      scope.$watch(attrs.dynamic, function(html) {
        ele.html(html);
        $compile(ele.contents())(scope);
      });
    }
  };
});

function MyController($scope) {
  $scope.click = function(arg) {
    alert('Clicked ' + arg);
  }
  $scope.html = '<a ng-click="click(1)" href="#">Click me</a>';
}

I agree the data attribute (voyager's answer) is how it should be handled, BUT, CSS rules like:

td.male { color: blue; }
td.female { color: pink; }

can often be much easier to set up, especially with client-side libs like angularjs which could be as simple as:

<td class="{{person.gender}}">

Just make sure that the content is only one word! Or you could even map to different CSS class names with:

<td ng-class="{'masculine': person.isMale(), 'feminine': person.isFemale()}">

For completeness, here's the data attribute approach:

<td data-gender="{{person.gender}}">

you can do something like this

/* CREATE USER DEFINED TABLE TYPE */

CREATE TYPE StateMaster AS TABLE
(
 StateCode VARCHAR(2),
 StateDescp VARCHAR(250)
)
GO

/*CREATE FUNCTION WHICH TAKES TABLE AS A PARAMETER */

CREATE FUNCTION TableValuedParameterExample(@TmpTable StateMaster READONLY)
RETURNS  VARCHAR(250)
AS
BEGIN
 DECLARE @StateDescp VARCHAR(250)
 SELECT @StateDescp = StateDescp FROM @TmpTable
 RETURN @StateDescp
END
GO

/*CREATE STORED PROCEDURE WHICH TAKES TABLE AS A PARAMETER */

CREATE PROCEDURE TableValuedParameterExample_SP
(
@TmpTable StateMaster READONLY
)
AS
BEGIN
 INSERT INTO StateMst 
  SELECT * FROM @TmpTable
END
GO


BEGIN
/* DECLARE VARIABLE OF TABLE USER DEFINED TYPE */
DECLARE @MyTable StateMaster

/* INSERT DATA INTO TABLE TYPE */
INSERT INTO @MyTable VALUES('11','AndhraPradesh')
INSERT INTO @MyTable VALUES('12','Assam')

/* EXECUTE STORED PROCEDURE */
EXEC TableValuedParameterExample_SP @MyTable
GO

class Program
{

    static void Main(string[] args)
    {

        //Load XML from local
        string sourceFileName="";
        string element=string.Empty;
        var FolderPath=@"D:\Test\RenameFileWithXmlAttribute";

            foreach (string xmlfile in files)
            {
                try
                {
                    sourceFileName = xmlfile;

You need to check for status 0 (as when loading files locally with XMLHttpRequest, you don't get a status returned because it's not from a Webserver)

function readTextFile(file)
{
    var rawFile = new XMLHttpRequest();
    rawFile.open("GET", file, false);
    rawFile.onreadystatechange = function ()
    {
        if(rawFile.readyState === 4)
        {
            if(rawFile.status === 200 || rawFile.status == 0)
            {
                var allText = rawFile.responseText;
                alert(allText);
            }
        }
    }
    rawFile.send(null);
}

And specify file:// in your filename:

readTextFile("file:///C:/your/path/to/file.txt");

Always google so you can locate the latest package for both NPP and NPP Plugins.

I googled "notepad++ 64bit". Downloaded the free latest version at Notepad++ (64-bit) - Free download and software. Installed notepad++ by double-click on npp.?.?.?.Installer.x64.exe, installed the .exe to default Windows 64bit path which is, "C:\Program Files".

Then, I googled "notepad++ 64 json viewer plug". Knowing SourceForge.Net is a renowned download site, downloaded JSToolNpp [email protected]. I unzipped and copied JSMinNPP.dll to notePad++ root dir.

I loaded my newly installed notepad++ 64bit. I went to Settings and selected [import plug-in]. I pointed to the location of JSMinNPP.dll and clicked open.

I reloaded notepad++, went to PlugIns menu. To format one-line json string to multi-line json doc, I clicked JSTool->JSFormat or reverse multi-line json doc to one-line json string by JSTool->JSMin (json-Minified)!

Additionally, if you don't want it to ask for a passphrase, then need to run the following command:

openssl rsa -in server.key -out server.key

Take a look in .git/config and make the changes you need.

Alternatively you could use

git remote rm [name of the url you sets on adding]

and

git remote add [name] [URL]

Or just

git remote set-url [URL]

Before you do anything wrong, double check with

git help remote

I had this problem using a prepared statement. I didn't add enough "?" for the "VALUES" My eclipse had crashed after I did add the proper amount, and lost those changes. But that didn't occur to me to be the error until I started combing through the SQL as p.campbell suggested.

The echo -e must have been failing for you because of wrong escaping. The following code works fine for me on a similar output from your_program with arguments:

echo -e $(your_program with arguments | sed -e 's/0x\(..\)\.\?/\\x\1/g')

Please note however that your original hexstring consists of non-printable characters.

EDIT

To avoid this error : The specified type member 'Date' is not supported in LINQ to Entities. Only initializers, entity members, and entity navigation properties are supported.

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true)
                         .Select(x => x).ToList();

 var filterdata = _My_ResetSet_Array
        .Where(x=>DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date)  <= 0 );

The second line is required because LINQ to Entity is not able to convert date property to sql query. So its better to first fetch the data and then apply the date filter.

EDIT

If you just want to compare the date value of the date time than make use of

DateTime.Date Property - Gets the date component of this instance.

Code for you

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true
     && DateTime.Compare(x.DateTimeValueColumn.Date, DateTime.Now.Date)  <= 0 )
                         .Select(x => x);

If its like that then use

DateTime.Compare Method - Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance.

Code for you

var _My_ResetSet_Array = _DB
                .tbl_MyTable
                .Where(x => x.Active == true
                  && DateTime.Compare(x.DateTimeValueColumn, DateTime.Now)  <= 0 )
                         .Select(x => x);

Example

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 1, 12, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";

Shift Pageup/End works for me.

getdate() or getutcdate().

I wrote next method as my solution (I hadn't any load indicator):

public static void waitForAjax(WebDriver driver, String action) {
       driver.manage().timeouts().setScriptTimeout(5, TimeUnit.SECONDS);
       ((JavascriptExecutor) driver).executeAsyncScript(
               "var callback = arguments[arguments.length - 1];" +
                       "var xhr = new XMLHttpRequest();" +
                       "xhr.open('POST', '/" + action + "', true);" +
                       "xhr.onreadystatechange = function() {" +
                       "  if (xhr.readyState == 4) {" +
                       "    callback(xhr.responseText);" +
                       "  }" +
                       "};" +
                       "xhr.send();");
}

Then I jsut called this method with actual driver. More description in this post.

You have to use max-width instead of min-width.

<style>
    @media (max-width: 1026px) {
        #test {
            display: none;
        }
    }
</style>
<div id="test">
    <h1>Test</h1>
</div>

See this brilliant blog post about animating values in objects.. you can then use the values to animate whatever you like, 100% simultaneously!

http://www.josscrowcroft.com/2011/code/jquery-animate-increment-decrement-numeric-text-elements-value/

I've used it like this to slide in/out:

        slide : function(id, prop, from, to) {
            if (from < to) {
                // Sliding out
                var fromvals = { add: from, subtract: 0 };
                var tovals = { add: to, subtract: 0 };
            } else {
                // Sliding back in
                var fromvals = { add: from, subtract: to };
                var tovals = { add: from, subtract: from };
            }

            $(fromvals).animate(tovals, {
                duration: 200,
                easing: 'swing', // can be anything
                step: function () { // called on every step
                    // Slide using the entire -ms-grid-columns setting
                    $(id).css(prop, (this.add - this.subtract) + 'px 1.5fr 0.3fr 8fr 3fr 5fr 0.5fr');
                }
            });
        }

In order to avoid this kind of ClassCastException, if you have:

class A
class B extends A

You can define a constructor in B that takes an object of A. This way we can do the "cast" e.g.:

public B(A a) {
    super(a.arg1, a.arg2); //arg1 and arg2 must be, at least, protected in class A
    // If B class has more attributes, then you would initilize them here
}

You have to wait until the browser knows the duration of the video before you can seek to a particular time. So, I think you want to wait for the 'loadedmetadata' event something like this:

document.getElementById('vid1').addEventListener('loadedmetadata', function() {
  this.currentTime = 50;
}, false);

private JSONObject uploadToServer() throws IOException, JSONException {
            String query = "https://example.com";
            String json = "{\"key\":1}";

            URL url = new URL(query);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setConnectTimeout(5000);
            conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setRequestMethod("POST");

            OutputStream os = conn.getOutputStream();
            os.write(json.getBytes("UTF-8"));
            os.close();

            // read the response
            InputStream in = new BufferedInputStream(conn.getInputStream());
            String result = org.apache.commons.io.IOUtils.toString(in, "UTF-8");
            JSONObject jsonObject = new JSONObject(result);


            in.close();
            conn.disconnect();

            return jsonObject;
    }

If you are using Action, Actionforward way to process business logic and next page to show, check out if redirect is called. As many others pointed out, redirecting doesn't keep your original request since it is basically forcing you to make a new request to designated path. So the value set in original request will be vanished if you use redirection instead of requestdispatch.

    public int MinimumValue { get; private set; }
    public int MaxmimumValue { get; private set; }

    public void num()
    {
        int[] array = { 12, 56, 89, 65, 61, 36, 45, 23 };
        MaxmimumValue = array[0];
        MinimumValue = array[0];

        foreach (int num in array)

        {

            if (num > MaxmimumValue) MaxmimumValue = num;
            if (num < MinimumValue) MinimumValue = num;
        }
        Console.WriteLine(MinimumValue);
        Console.WriteLine(MaxmimumValue);
    }

Besides the redundant ) this expression will always be true because currentStatus will always match one of these two conditions:

currentStatus !== 'open' || currentStatus !== 'reopen'

perhaps you mean one of

!(currentStatus === 'open' || currentStatus === 'reopen')
(currentStatus !== 'open' && currentStatus !== 'reopen')

Just check against null.

($myObject.MyProperty -ne $null)

If you have not set PowerShell to StrictMode, this works even if the property does not exist:

$obj = New-Object PSObject;                                                   
Add-Member -InputObject $obj -MemberType NoteProperty -Name Foo -Value "Bar";
$obj.Foo; # Bar                                                                  
($obj.MyProperty -ne $null);  # False, no exception

does your proxy require you to authenticate? because if it does, you might want you configure your proxy like this.

placeholder names. username is a placeholder for your actual username. password is a placeholder for your actual password. proxy.company.com is a placeholder for your actualy proxy *port" is your actualy port the proxy goes through. its usualy 8080

npm config set proxy "http://username:[email protected]:port"
npm config set https-proxy "http://username:[email protected]:port"

Here is a Kotlin version based on the accepted answer.

I'm using this dialog from an adapter, every time a button is clicked.

yourButton.setOnClickListener {
    showDialog(it /*here I pass additional arguments*/)
}

In order to prevent double clicks I immediately disable the button, and re-enable after the action is executed / cancelled.

private fun showDialog(view: View /*additional parameters*/) {
    view.isEnabled = false

    val builder = AlertDialog.Builder(context)
    builder.setTitle(R.string.your_dialog_title)

    val options = arrayOf("Option A", "Option B")

    builder.setItems(options) { dialog, which ->
        dialog.dismiss()

        when (which) {
            /* execute here your actions */
            0 -> context.toast("Selected option A")
            1 -> context.toast("Selected option B")
        }

        view.isEnabled = true
    }

    builder.setOnCancelListener {
        view.isEnabled = true
    }

    builder.show()
}

You can use this instead of a context variable if you are using it from an Activity.

protected void gvLogMessageDetail_RowDataBound(object sender, GridViewRowEventArgs e)  
    { 
      if (e.Row.RowType == DataControlRowType.Header)   
        {  
            if (rdlForImportOrExport.SelectedIndex == 1)  
            {  
                e.Row.Cells[3].Visible = false;  
                e.Row.Cells[4].Visible = false;  
                e.Row.Cells[5].Visible = false;  
            }  
            else  
            {  
                e.Row.Cells[3].Visible = true;  
                e.Row.Cells[4].Visible = true;  
                e.Row.Cells[5].Visible = true;  
            }  
        }    
        if (e.Row.RowType == DataControlRowType.DataRow) //skip header row  
        {  
            try  
            {  
                if (rdlForImportOrExport.SelectedIndex == 1)  
                {  
                    e.Row.Cells[3].Visible = false;  
                    e.Row.Cells[4].Visible = false;  
                    e.Row.Cells[5].Visible = false;  
                }  
                else  
                {  
                    e.Row.Cells[3].Visible = true;  
                    e.Row.Cells[4].Visible = true;  
                    e.Row.Cells[5].Visible = true;  
                }  
                }  
            catch  
            {  
                ClientScript.RegisterStartupScript(GetType(), "Expand", "<SCRIPT   LANGUAGE='javascript'>alert('There is binding problem in child grid.');</script>");  
            }  
        }  
    }  

If you just need to hit C# Method on in your Ajax Call you just need to pass two matter type and url if your request is get then you just need to specify the url only. please follow the code below it's working fine.

C# Code:

    [HttpGet]
    public ActionResult FirstAjax()
    {
        return Json("chamara", JsonRequestBehavior.AllowGet);
    }   

Java Script Code if Get Request

    $.ajax({
        url: 'home/FirstAjax',
        success: function(responce){ alert(responce.data)},
        error: function(responce){ alert(responce.data)}
    });

Java Script Code if Post Request and also [HttpGet] to [HttpPost]

        $.ajax({
            url: 'home/FirstAjax',
            type:'POST',
            success: function(responce){ alert(responce)},
            error: function(responce){ alert(responce)}
        });

Note: If you FirstAjax in same controller in which your View Controller then no need for Controller name in url. like url: 'FirstAjax',

This works for me in my onClickListener:

yourView.postDelayed(new Runnable() {               
    @Override
    public void run() {         
        yourView.invalidate();
        System.out.println("Height yourView: " + yourView.getHeight());
        System.out.println("Width yourView: " + yourView.getWidth());               
    }
}, 1);

Well, setTimeout, per its definition, will not hold up the thread. This is desirable, because if it did, it'd freeze the entire UI for the time it was waiting. if you really need to use setTimeout, then you should be using callback functions:

function myfunction() {
    longfunctionfirst(shortfunctionsecond);
}

function longfunctionfirst(callback) {
    setTimeout(function() {
        alert('first function finished');
        if(typeof callback == 'function')
            callback();
    }, 3000);
};

function shortfunctionsecond() {
    setTimeout('alert("second function finished");', 200);
};

If you are not using setTimeout, but are just having functions that execute for very long, and were using setTimeout to simulate that, then your functions would actually be synchronous, and you would not have this problem at all. It should be noted, though, that AJAX requests are asynchronous, and will, just as setTimeout, not hold up the UI thread until it has finished. With AJAX, as with setTimeout, you'll have to work with callbacks.

I resolved the error by force stopping (killed) git processes (ssh agent), then uninstalling Git, and then installing Git again.

YES, You can do this on bellow ways:

1. By CrudRepository (Projection)

Spring Data Repositories usually return the domain model when using query methods. However, sometimes, you may need to alter the view of that model for various reasons.

Suppose your entity is like this :

    import javax.persistence.*;
    import java.math.BigDecimal;

    @Entity
    @Table(name = "USER_INFO_TEST")
    public class UserInfoTest {
        private int id;
        private String name;
        private String rollNo;

        public UserInfoTest() {
        }

        public UserInfoTest(int id, String name) {
        this.id = id;
        this.name = name;
        }

        @Id
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        @Column(name = "ID", nullable = false, precision = 0)
        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        @Basic
        @Column(name = "name", nullable = true)
        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        @Basic
        @Column(name = "roll_no", nullable = true)
        public String getRollNo() {
            return rollNo;
        }

        public void setRollNo(String rollNo) {
            this.rollNo = rollNo;
        }
    }

Now your Projection class is like bellow. It can those fields that you needed.

public interface IUserProjection {
     int getId();
     String getName();
     String getRollNo();
}

And Your Data Access Object(Dao) is like bellow :

import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.CrudRepository;

import java.util.ArrayList;

public interface UserInfoTestDao extends CrudRepository<UserInfoTest,Integer> {
    @Query(value = "select id,name,roll_no from USER_INFO_TEST where rollNo = ?1", nativeQuery = true)
    ArrayList<IUserProjection> findUserUsingRollNo(String rollNo);
}

Now ArrayList<IUserProjection> findUserUsingRollNo(String rollNo) will give you the list of user.

2. Using EntityManager

Suppose your query is "select id,name from users where roll_no = 1001".

Here query will return a object with id and name column. Your Response class is like bellow:

Your Response class is like:

public class UserObject{
        int id;
        String name;
        String rollNo;

        public UserObject(Object[] columns) {
            this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
            this.name = (String) columns[1];
        }

        public int getId() {
            return id;
        }

        public void setId(int id) {
            this.id = id;
        }

        public String getName() {
            return name;
        }

        public void setName(String name) {
            this.name = name;
        }

        public String getRollNo() {
            return rollNo;
        }

        public void setRollNo(String rollNo) {
            this.rollNo = rollNo;
        }
    }

here UserObject constructor will get a Object Array and set data with object.

public UserObject(Object[] columns) {
            this.id = (columns[0] != null)?((BigDecimal)columns[0]).intValue():0;
            this.name = (String) columns[1];
        }

Your query executing function is like bellow :

public UserObject getUserByRoll(EntityManager entityManager,String rollNo) {

        String queryStr = "select id,name from users where roll_no = ?1";
        try {
            Query query = entityManager.createNativeQuery(queryStr);
            query.setParameter(1, rollNo);

            return new UserObject((Object[]) query.getSingleResult());
        } catch (Exception e) {
            e.printStackTrace();
            throw e;
        }
    }

Here you have to import bellow packages:

import javax.persistence.Query;
import javax.persistence.EntityManager;

Now your main class, you have to call this function. First get EntityManager and call this getUserByRoll(EntityManager entityManager,String rollNo) function. Calling procedure is given bellow:

Here is the Imports

import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

get EntityManager from this way:

@PersistenceContext
private EntityManager entityManager;

UserObject userObject = getUserByRoll(entityManager,"1001");

Now you have data in this userObject.

Note:

query.getSingleResult() return a object array. You have to maintain the column position and data type with query column position.

select id,name from users where roll_no = 1001 

query return a array and it's [0] --> id and [1] -> name.
