T(n)=T(n/2)+1

T(n/2)= T(n/4)+1+1

Put the value of The(n/2) in above so T(n)=T(n/4)+1+1 . . . . T(n/2^k)+1+1+1.....+1

=T(2^k/2^k)+1+1....+1 up to k

=T(1)+k

As we taken 2^k=n

K = log n

So Time complexity is O(log n)

Using auxiliary Result class to track if node is found and current k.

public class KthSmallestElementWithAux {

public int kthsmallest(TreeNode a, int k) {
    TreeNode ans = kthsmallestRec(a, k).node;
    if (ans != null) {
        return ans.val;
    } else {
        return -1;
    }
}

private Result kthsmallestRec(TreeNode a, int k) {
    //Leaf node, do nothing and return
    if (a == null) {
        return new Result(k, null);
    }

    //Search left first
    Result leftSearch = kthsmallestRec(a.left, k);

    //We are done, no need to check right.
    if (leftSearch.node != null) {
        return leftSearch;
    }

    //Consider number of nodes found to the left
    k = leftSearch.k;

    //Check if current root is the solution before going right
    k--;
    if (k == 0) {
        return new Result(k - 1, a);
    }

    //Check right
    Result rightBalanced = kthsmallestRec(a.right, k);

    //Consider all nodes found to the right
    k = rightBalanced.k;

    if (rightBalanced.node != null) {
        return rightBalanced;
    }

    //No node found, recursion will continue at the higher level
    return new Result(k, null);

}

private class Result {
    private final int k;
    private final TreeNode node;

    Result(int max, TreeNode node) {
        this.k = max;
        this.node = node;
    }
}
}

You can use the localeCompare() method.

string_a.localeCompare(string_b);

/* Expected Returns:

 0:  exact match

-1:  string_a < string_b

 1:  string_a > string_b

 */

Try this: Pick a random name "Lastname, Firstname" and look it up in your phonebook.

1st time: start at the beginning of the book, reading names until you find it, or else find the place where it would have occurred alphabetically and note that it isn't there.

2nd time: Open the book at the half way point and look at the page. Ask yourself, should this person be to the left or to the right. Whichever one it is, take that 1/2 and find the middle of it. Repeat this procedure until you find the page where the entry should be and then either apply the same process to columns, or just search linearly along the names on the page as before.

Time both methods and report back!

[also consider what approach is better if all you have is a list of names, not sorted...]

Please rewrite your query like

select /*+ MAX_EXECUTION_TIME(1000) */ * from table

this statement will kill your query after the specified time

You can append a queryString to your src and change it only when you will release an updated version:

<script src="test.js?v=1"></script>

In this way the browser will use the cached version until a new version will be specified (v=2, v=3...)

Since there is only one WiFi hardware on the computer its not possible to connect one WiFi hardware to multiple WiFi networks, if you want to that I think you have to map WiFi hardware to guest OS and how host you'll have to use some other hardware (may be Ethernet) but I'm sure that it will work in that way as no VM software allow us to allocate Hardware to Guest except for USB, you can also get USB WiFI and allocate that to VM only.

1. Go to the log view (to be able to go here go to View -> log view).
2. Double click on the line with the branch label stating that branch. Automatically, it will switch branch. (A prompt will dropdown and say switching branch.)
3. If you have two or more branches on the same line, it will ask you via prompt which branch you want to switch. Choose the specific branch from the dropdown and click ok.

To determine which branch you are now on, look at the side bar, under BRANCHES, you are in the branch that is in BOLD LETTERS.

select substring(ColumnName, patindex('%[^0]%',ColumnName), 10)

The second option is completely fine. I'm not sure why a responder said it was not possible. This is fine, and I do this all the time:

switch (variable)
{
    case 5:
    case 6:
    etc.
    case 100:
        doSomething();
    break;
}

Html.CheckBox is doing something weird - if you view source on the resulting page, you'll see there's an <input type="hidden" /> being generated alongside each checkbox, which explains the "true false" values you're seeing for each form element.

Try this, which definitely works on ASP.NET MVC Beta because I've just tried it.

Put this in the view instead of using Html.CheckBox():

<% using (Html.BeginForm("ShowData", "Home")) {  %>
  <% foreach (var o in ViewData.Model) { %>
    <input type="checkbox" name="selectedObjects" value="<%=o.Id%>">
    <%= o.Name %>
  <%}%>
  <input type="submit" value="Submit" />
<%}%>

Your checkboxes are all called selectedObjects, and the value of each checkbox is the GUID of the corresponding object.

Then post to the following controller action (or something similar that does something useful instead of Response.Write())

public ActionResult ShowData(Guid[] selectedObjects) {
    foreach (Guid guid in selectedObjects) {
        Response.Write(guid.ToString());
    }
    Response.End();
    return (new EmptyResult());
}

This example will just write the GUIDs of the boxes you checked; ASP.NET MVC maps the GUID values of the selected checkboxes into the Guid[] selectedObjects parameter for you, and even parses the strings from the Request.Form collection into instantied GUID objects, which I think is rather nice.

If you don't feel like importing anything, you can try:

raise SystemExit, 0

Use mavenCentral() or jcenter() adding in the build.gradle file the script:

buildscript {

A note regarding sizes

As Salman A mentioned in the comments, we need to set the img's position coordinates (top, left, bottom, right) to work with percents higher than the image's actual dimensions. I use 1000% in the above example, but of course you can adjust it according to your needs.

* Further explanation: When we set the img's left and right (or: top and bottom) coordinates to be -100% (of the containing div), the overall allowed width (or: height) of the img, can be at most 300% of the containing div's width (or: height), because it's the sum of the div's width (or: height) and the left and right (or: top and bottom) coordinates.

Make sure upload plugin implements this.each in it so that it will execute the logic for all the matching elements. It should ideally work

$("#upload_link,#upload_link2,#upload_link3").upload(function(){ });

The shortest way would be:

$("#" + row_id)

Limiting the search to the body doesn't have any benefit.

Also, you should consider renaming your ids to something more meaningful (and HTML compliant as per Paolo's answer), especially if you have another set of data that needs to be named as well.

1st way is to use props

<Row id = "someRandomID">

Wherein, in the Definition, you may just go

const Row = props  => {
 div id = {props.id}
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.

Nobody mentioned the limit on the size of the stack frame.

There are two places memory can be allocated:

• On the heap (dynamically allocated memory).
  The size limit here is a combination of available hardware and the OS's ability to simulate space by using other devices to temporarily store unused data (i.e. move pages to hard disk).
• On the stack (Locally declared variables).
  The size limit here is compiler defined (with possible hardware limits). If you read the compiler documentation you can often tweak this size.

Thus if you allocate an array dynamically (the limit is large and described in detail by other posts.

int* a1 = new int[SIZE];  // SIZE limited only by OS/Hardware

Alternatively if the array is allocated on the stack then you are limited by the size of the stack frame. N.B. vectors and other containers have a small presence in the stack but usually the bulk of the data will be on the heap.

int a2[SIZE]; // SIZE limited by COMPILER to the size of the stack frame

Here is formula which I discover and precisely describe in wiki + error analysis,

Use the following code for getting lat and long using php. Here are two methods:

Type-1:

    <?php
     // Get lat and long by address         
        $address = $dlocation; // Google HQ
        $prepAddr = str_replace(' ','+',$address);
        $geocode=file_get_contents('https://maps.google.com/maps/api/geocode/json?address='.$prepAddr.'&sensor=false');
        $output= json_decode($geocode);
        $latitude = $output->results[0]->geometry->location->lat;
        $longitude = $output->results[0]->geometry->location->lng;

?>

edit - Google Maps requests must be over https

Type-2:

<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
     <script>
      var geocoder;
      var map;
      function initialize() {
        geocoder = new google.maps.Geocoder();
         var latlng = new google.maps.LatLng(50.804400, -1.147250);
        var mapOptions = {
         zoom: 6,
         center: latlng
        }
         map = new google.maps.Map(document.getElementById('map-canvas12'), mapOptions);
        }

       function codeAddress(address,tutorname,url,distance,prise,postcode) {
       var address = address;

        geocoder.geocode( { 'address': address}, function(results, status) {
         if (status == google.maps.GeocoderStatus.OK) {
          map.setCenter(results[0].geometry.location);
           var marker = new google.maps.Marker({
          map: map,
          position: results[0].geometry.location
      });

      var infowindow = new google.maps.InfoWindow({
         content: 'Tutor Name: '+tutorname+'<br>Price Guide: '+prise+'<br>Distance: '+distance+' Miles from you('+postcode+')<br> <a href="'+url+'" target="blank">View Tutor profile</a> '
       });
        infowindow.open(map,marker);

          } /*else {
          alert('Geocode was not successful for the following reason: ' + status);
        }*/
       });
     }


      google.maps.event.addDomListener(window, 'load', initialize);

     window.onload = function(){
      initialize();
      // your code here
      <?php foreach($addr as $add) { 

      ?>
      codeAddress('<?php echo $add['address']; ?>','<?php echo $add['tutorname']; ?>','<?php echo $add['url']; ?>','<?php echo $add['distance']; ?>','<?php echo $add['prise']; ?>','<?php echo substr( $postcode1,0,4); ?>');
      <?php } ?>
    };
      </script>

     <div id="map-canvas12"></div>

The platform is not specified, but in C# (.NET) it would be:

Regular expression (presumes the multiline option - the example below uses it):

    [ \t]+(\r?$)

Replacement:

    $1

For an explanation of "\r?$", see Regular Expression Options, Multiline Mode (MSDN).

Code example

This will remove all trailing spaces and all trailing TABs in all lines:

string inputText = "     Hello, World!  \r\n" +
                   "  Some other line\r\n" +
                   "     The last line  ";
string cleanedUpText = Regex.Replace(inputText,
                                     @"[ \t]+(\r?$)", @"$1",
                                     RegexOptions.Multiline);

For a reason I don't yet understand, after I used <%@include file="includes/footer.jsp" %> in my index.jsp then in the other jsp files like register.jsp I had to use <%@ include file="footer.jsp"%>. As you see there was no more need to use full path, STS had store my initial path.

Check out the manual: http://www.php.net/manual/en/datetime.format.php

<?php
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:s');
?>

Will output: 2000-01-01 00:00:00

In order to add attributes, XSL wants

<xsl:element name="img">
     (attributes)
</xsl:element>

instead of just

<img>
     (attributes)
</img>

Although, yes, if you're just copying the element as-is, you don't need any of that.

it depends on your php settings...
use phpinfo() and take a look at the session chapter. There are values like session.gc_maxlifetime and session.cache_expire and session.cookie_lifetime which affects the sessions lifetime

EDIT: it's like Martin write before

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

I'll tell you how it can be done in eclipse. My dev system - Windows 64bit, Eclipse Luna, Perlipse plugin for eclipse, Strawberry pearl installer. I use perl.exe as my interpreter.

Eclipse > create new perl project > right click project > build path > configure build path > libraries tab > add external source folder > go to the folder where all your perl modules are installed > ok > ok. Done !

I wrote an extension method of DataRow which gets me the object via the column name.

public static object Column(this DataRow source, string columnName)
{
    var c = source.Table.Columns[columnName];
    if (c != null)
    {
        return source.ItemArray[c.Ordinal];
    }

    throw new ObjectNotFoundException(string.Format("The column '{0}' was not found in this table", columnName));
}

And its called like this:

DataTable data = LoadDataTable();
foreach (DataRow row in data.Rows)
{        
    var obj = row.Column("YourColumnName");
    Console.WriteLine(obj);
}

Use eval:

x="ls | wc"
eval "$x"
y=$(eval "$x")
echo "$y"

check this, you should give arguments in msecs, Dont just send progress to seekTo(int)

and also check this getCurrentPostion() and getDuration().

You can do some calcuations, ie., convert progress in msec like msce = (progress/100)*getDuration() then do seekTo(msec)

Or else i have an easy idea, you don't need to change any code anywer else just add seekBar.setMax(mPlayer.getDuration()) once your media player is prepared.

and here is link exactly what you want seek bar update

As noted in the official documentation, simply apply the class(es) btn btn-link:

<!-- Deemphasize a button by making it look like a link while maintaining button behavior -->
<button type="button" class="btn btn-link">Link</button>

For example, with the code you have provided:

<link href="//maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet" />_x000D_
_x000D_
_x000D_
<form action="..." method="post">_x000D_
  <div class="row-fluid">_x000D_
    <!-- Navigation for the form -->_x000D_
    <div class="span3">_x000D_
      <ul class="nav nav-tabs nav-stacked">_x000D_
        <li>_x000D_
          <button class="btn btn-link" role="link" type="submit" name="op" value="Link 1">Link 1</button>_x000D_
        </li>_x000D_
        <li>_x000D_
          <button class="btn btn-link" role="link" type="submit" name="op" value="Link 2">Link 2</button>_x000D_
        </li>_x000D_
        <!-- ... -->_x000D_
      </ul>_x000D_
    </div>_x000D_
    <!-- The actual form -->_x000D_
    <div class="span9">_x000D_
      <!-- ... -->_x000D_
    </div>_x000D_
  </div>_x000D_
</form>

I had to disable this in chrome://flags

import * as express from "express";

This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.

In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());

There are several good answers on here but I wanted to add one since it may be helpful for users like me who have Tomcat installed as a service on a Windows machine.

Option 3 here: http://www.codejava.net/servers/tomcat/4-ways-to-change-jre-for-tomcat

Basically, open tomcatw.exe and point Tomcat to the version of the JVM you need to use then restart the service. Ensure your deployed applications still work as well.

I sort of agree with leander on this one.

call:

new calc_stanica().execute(stringList.toArray(new String[stringList.size()]));

task:

public class calc_stanica extends AsyncTask<String, Void, ArrayList<String>> {
        @Override
        protected ArrayList<String> doInBackground(String... args) {
           ...
        }

        @Override
        protected void onPostExecute(ArrayList<String> result) {
           ... //do something with the result list here
        }
}

Or you could just make the result list a class parameter and replace the ArrayList with a boolean (success/failure);

public class calc_stanica extends AsyncTask<String, Void, Boolean> {
        private List<String> resultList;

        @Override
        protected boolean doInBackground(String... args) {
           ...
        }

        @Override
        protected void onPostExecute(boolean success) {
           ... //if successfull, do something with the result list here
        }
}

Generally, you cannot send a POST request using sendRedirect() method. You can use RequestDispatcher to forward() requests with parameters within the same web application, same context.

RequestDispatcher dispatcher = servletContext().getRequestDispatcher("test.jsp");
dispatcher.forward(request, response);

The HTTP spec states that all redirects must be in the form of a GET (or HEAD). You can consider encrypting your query string parameters if security is an issue. Another way is you can POST to the target by having a hidden form with method POST and submitting it with javascript when the page is loaded.

To turn "tools" into a module, I don't see hard at all. Despite all the other answers I would still recommend use of module.exports:

//util.js
module.exports = {
   myFunction: function () {
   // your logic in here
   let message = "I am message from myFunction";
   return message; 
  }
}

Now we need to assign this exports to global scope (in your app|index|server.js )

var util = require('./util');

Now you can refer and call function as:

//util.myFunction();

Maybe you could use String#split

To answer your comment:

I'm not sure if there can be more than one . in a filename, but whatever, even if there are more dots you can use the split. Consider e.g. that:

String input = "boo.and.foo";

String[] result = input.split(".");

This will return an array containing:

{ "boo", "and", "foo" }

So you will know that the last index in the array is the extension and all others are the base.

See TRY...CATCH (Transact-SQL)

 CREATE PROCEDURE [dbo].[PL_GEN_PROVN_NO1]        
       @GAD_COMP_CODE  VARCHAR(2) =NULL, 
       @@voucher_no numeric =null output 
       AS         
   BEGIN  

     begin try 
         -- your proc code
     end try

     begin catch
          -- what you want to do in catch
     end catch    
  END -- proc end

In most cases (including this one), return will exit immediately. However, if the return is in a try block with an accompanying finally block, the finally always executes and can "override" the return in the try.

function foo() {
    try {
        for (var i = 0; i < 10; i++) {
            if (i % 3 == 0) {
                return i; // This executes once
            }
        }
    } finally {
        return 42; // But this still executes
    }
}

console.log(foo()); // Prints 42

Short and clear answer

• High cohesion: Elements within one class/module should functionally belong together and do one particular thing.
• Loose coupling: Among different classes/modules should be minimal dependency.

Maybe use in between better. It worked for me to get range then filter it

well we don't have enough to answer this question so I will give you several guesses:

1) you stashed your changes, to fix type: git stash pop

2) you had changes and you committed them, you should be able to see your commit in git log

3) you had changes did some sort of git reset --hard or other, your changes may be there in the reflog, type git reflog --all followed by checking out or cherry-picking the ref if you ever do find it.

4) you have checked out the same repo several times, and you are in the wrong one.

Use the DATEDIFF to return value in milliseconds, seconds, minutes, hours, ...

DATEDIFF(interval, date1, date2)

interval REQUIRED - The time/date part to return. Can be one of the following values:

year, yyyy, yy = Year
quarter, qq, q = Quarter
month, mm, m = month
dayofyear = Day of the year
day, dy, y = Day
week, ww, wk = Week
weekday, dw, w = Weekday
hour, hh = hour
minute, mi, n = Minute
second, ss, s = Second
millisecond, ms = Millisecond

date1, date2 REQUIRED - The two dates to calculate the difference between

For me perfectly fork this code.

$('#dom_object_id').on('change paste keyup', function(){
    console.log($("#dom_object_id").val().length)
});

Key event for .on() function is "paste" to get changes dynamically

Sql server internally build the script. It create a temporary table with new changes and copy the data and drop current table then recreate the table insert from temp table. I find it from "Generate Change script" option ssms 2014. Script like this. From Here: How to change column order in a table using sql query

If you need to fetch an object's property dynamically, use the getattr() function: getattr(user, "fullName") - or to elaborate:

user = User()
property = "fullName"
name = getattr(user, property)

Otherwise just use user.fullName.

Never, you can't do it since package name is the unique name Identifier for your app.....

Try this:

<?php
  $date = date_parse('July');
  var_dump($date['month']);
?>

From Microsoft documentation:

PAGEIOLATCH_SH

Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem.

In practice, this almost always happens due to large scans over big tables. It almost never happens in queries that use indexes efficiently.

If your query is like this:

Select * from <table> where <col1> = <value> order by <PrimaryKey>

, check that you have a composite index on (col1, col_primary_key).

If you don't have one, then you'll need either a full INDEX SCAN if the PRIMARY KEY is chosen, or a SORT if an index on col1 is chosen.

Both of them are very disk I/O consuming operations on large tables.

I faced exactly the same issue. My home drive mapped to a network drive. Also

1. No Write access to home drive
2. No write access to Git bash profile
3. No admin rights to change environment variables from control panel.

However below worked from command line and I was able to add HOME to environment variables.

You can make use of location service available in @angular/common and via this below code you can get the location or current URL

import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router';

@Component({
  selector: 'app-top-nav',
  templateUrl: './top-nav.component.html',
  styleUrls: ['./top-nav.component.scss']
})
export class TopNavComponent implements OnInit {

  route: string;

  constructor(location: Location, router: Router) {
    router.events.subscribe((val) => {
      if(location.path() != ''){
        this.route = location.path();
      } else {
        this.route = 'Home'
      }
    });
  }

  ngOnInit() {
  }

}

here is the reference link from where I have copied thing to get location for my project. https://github.com/elliotforbes/angular-2-admin/blob/master/src/app/common/top-nav/top-nav.component.ts

There's no built-in command for that because it's illegal. You can't modify the size of an array once declared.

What you're looking for is either std::vector to simulate a dynamic array, or better yet a std::string.

std::string first ("The dog jumps ");
std::string second ("over the log");
std::cout << first + second << std::endl;

<body oncontextmenu="return false;"> works for me in Google Chrome. Not sure about other browsers.

Note, all someone has to do is disable JavaScript in order to see the right-click menu anyway.

I know it really late for another answer but I just wanted to share what helped me at the end. It will also load resources/files from the absolute path of the file system (not only the classpath's).

public class ResourceLoader {

    public static URL getResource(String resource) {
        final List<ClassLoader> classLoaders = new ArrayList<ClassLoader>();
        classLoaders.add(Thread.currentThread().getContextClassLoader());
        classLoaders.add(ResourceLoader.class.getClassLoader());

        for (ClassLoader classLoader : classLoaders) {
            final URL url = getResourceWith(classLoader, resource);
            if (url != null) {
                return url;
            }
        }

        final URL systemResource = ClassLoader.getSystemResource(resource);
        if (systemResource != null) {
            return systemResource;
        } else {
            try {
                return new File(resource).toURI().toURL();
            } catch (MalformedURLException e) {
                return null;
            }
        }
    }

    private static URL getResourceWith(ClassLoader classLoader, String resource) {
        if (classLoader != null) {
            return classLoader.getResource(resource);
        }
        return null;
    }

}

I've concluded this is some kind of Visual Studio bug. Perhaps C Johnson is right - perhaps the build process keeps the file locked.

I do have a workaround which works - each time this happens - I change the Target Name of the executable under the Project's properties (right click the project, then Properties\Configuration Properties\General\Target Name).

In this fashion VS creates a new executable and the problem is worked around. Every few times I do this I return to the original name, thus cycling through ~3 names.

If someone will find the reason for this and a solution, please do answer and I may move the answer to yours, as mine is a workaround.

If you want to reassign an element in an array, you can do the following:

var blah = ['Jan', 'Fed', 'Apr'];

console.log(blah);

function reassign(array, index, newValue) {
    array[index] = newValue;
    return array;
}

reassign(blah, [2], 'Mar');

An iframe is universally handled like a different HTML page by most browsers. If you want to apply the same stylesheet to the content of the iframe, just reference it from the pages used in there.

This a great example about share with Intents in Android:

* Share with Intents in Android

//Share text:

Intent intent2 = new Intent(); intent2.setAction(Intent.ACTION_SEND);
intent2.setType("text/plain");
intent2.putExtra(Intent.EXTRA_TEXT, "Your text here" );  
startActivity(Intent.createChooser(intent2, "Share via"));

//via Email:

Intent intent2 = new Intent();
intent2.setAction(Intent.ACTION_SEND);
intent2.setType("message/rfc822");
intent2.putExtra(Intent.EXTRA_EMAIL, new String[]{EMAIL1, EMAIL2});
intent2.putExtra(Intent.EXTRA_SUBJECT, "Email Subject");
intent2.putExtra(Intent.EXTRA_TEXT, "Your text here" );  
startActivity(intent2);

//Share Files:

//Image:

boolean isPNG = (path.toLowerCase().endsWith(".png")) ? true : false;

Intent i = new Intent(Intent.ACTION_SEND);
//Set type of file
if(isPNG)
{
    i.setType("image/png");//With png image file or set "image/*" type
}
else
{
    i.setType("image/jpeg");
}

Uri imgUri = Uri.fromFile(new File(path));//Absolute Path of image
i.putExtra(Intent.EXTRA_STREAM, imgUri);//Uri of image
startActivity(Intent.createChooser(i, "Share via"));
break;

//APK:

File f = new File(path1);
if(f.exists())
{

   Intent intent2 = new Intent();
   intent2.setAction(Intent.ACTION_SEND);
   intent2.setType("application/vnd.android.package-archive");//APk file type  
   intent2.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(f) );  
   startActivity(Intent.createChooser(intent2, "Share via"));
}
break;

For radioButton use

radio1.setChecked(true);

It does not make sense to have just one RadioButton. If you have more of them you need to uncheck others through

radio2.setChecked(false); ...

If your setting is just on/off use CheckBox.

The accepted answer being said, It is missing some explanations. For example, what is the difference between a uni-directional and a bi-directional association? In the provided example, both do exist. ( Both '5's in the arrows)

If looking for a more complete answer and have more time, here is a thorough explanation.

You can try this:

function Get-UrlStatusCode([string] $Url)
{
    try
    {
        (Invoke-WebRequest -Uri $Url -UseBasicParsing -DisableKeepAlive).StatusCode
    }
    catch [Net.WebException]
    {
        [int]$_.Exception.Response.StatusCode
    }
}

$statusCode = Get-UrlStatusCode 'httpstat.us/500'

I'll add this in here as my problem had something todo with my virtualenv:

I hadn't activated my virtual environment and was trying to install my requirements, this ultimately led to my install failing and throwing this error message.

So make sure you activate your virtualenv!

If you (or a helpful admin) runs Set-ExecutionPolicy as administrator, the policy will be set for all users. (I would suggest "remoteSigned" rather than "unrestricted" as a safety measure.)

NB.: On a 64-bit OS you need to run Set-ExecutionPolicy for 32-bit and 64-bit PowerShell separately.

Also, make sure there are no line breaks in the post build event editing window on your project. Sometimes copying the xcopy command from the web when it's multi-line and pasting it into VS will cause a problem.

The reason i could not delete some of the users via 'drop' statement was that there is a bug in Mysql http://bugs.mysql.com/bug.php?id=62255 with hostname containing upper case letters. The solution was running following query:

DELETE FROM mysql.user where host='Some_Host_With_UpperCase_Letters';

I am still trying to figure the other issue where the root user with all permissions are unable to grant privileges to new user for particular database

As was stated, your reader needs to be 'step' scoped. You can accomplish this via the @Scope("step") annotation. It should work for you if you add that annotation to your reader, like the following:

import org.springframework.batch.item.ItemReader;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;

@Component("foo-reader")
@Scope("step")
public final class MyReader implements ItemReader<MyData> {
  @Override
  public MyData read() throws Exception {
    //...
  }

  @Value("#{jobParameters['fileName']}")
  public void setFileName(final String name) {
    //...
  }
}

This scope is not available by default, but will be if you are using the batch XML namespace. If you are not, adding the following to your Spring configuration will make the scope available, per the Spring Batch documentation:

<bean class="org.springframework.batch.core.scope.StepScope" />

Simply:

/^([^0-9]*)$/

That pattern matches any number of characters that is not 0 through 9.

I recommend checking out http://regexpal.com/. It will let you easily test out a regex.

For Windows, CaptureStackBackTrace() is also an option, which requires less preparation code on the user's end than StackWalk64() does. (Also, for a similar scenario I had, CaptureStackBackTrace() ended up working better (more reliably) than StackWalk64().)

You may also want to have a look at httplib2, with examples. I find using httplib2 is more concise than using the built-in HTTP modules.

Try using

Decimal(19,4)

this usually works with every other DB as well

If you don't want to block the current thread by waiting/checking for the other running thread completion, you can implement callback method like this.

Action onCompleted = () => 
{  
    //On complete action
};

var thread = new Thread(
  () =>
  {
    try
    {
      // Do your work
    }
    finally
    {
      onCompleted();
    }
  });
thread.Start();

If you are dealing with controls that doesn't support cross-thread operation, then you have to invoke the callback method

this.Invoke(onCompleted);

If you are using IntelliJ IDEA or Android Studio:

Go to Settings > Editor > General >Auto Import and check the Optimize imports on the fly checkbox.

Remove these two lines:

xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");

XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

I'm surprised nobody has mentioned the new Fetch API, supported by all browsers except IE11 at the time of writing. It simplifies the XMLHttpRequest syntax you see in many of the other examples.

The API includes a lot more, but start with the fetch() method. It takes two arguments:

1. A URL or an object representing the request.
2. Optional init object containing the method, headers, body etc.

Simple GET:

const userAction = async () => {
  const response = await fetch('http://example.com/movies.json');
  const myJson = await response.json(); //extract JSON from the http response
  // do something with myJson
}

Recreating the previous top answer, a POST:

const userAction = async () => {
  const response = await fetch('http://example.com/movies.json', {
    method: 'POST',
    body: myBody, // string or object
    headers: {
      'Content-Type': 'application/json'
    }
  });
  const myJson = await response.json(); //extract JSON from the http response
  // do something with myJson
}

Here's a fun demo of controlling the various states of the console, including minimize and hidden.

Add-Type -Name ConsoleUtils -Namespace WPIA -MemberDefinition @'
   [DllImport("Kernel32.dll")]
   public static extern IntPtr GetConsoleWindow();
   [DllImport("user32.dll")]
   public static extern bool ShowWindow(IntPtr hWnd, Int32 nCmdShow);
'@

$ConsoleMode = @{
 HIDDEN = 0;
 NORMAL = 1;
 MINIMIZED = 2;
 MAXIMIZED = 3;
 SHOW = 5
 RESTORE = 9
 }

$hWnd = [WPIA.ConsoleUtils]::GetConsoleWindow()

$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.MAXIMIZED)
"maximized $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.NORMAL)
"normal $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.MINIMIZED)
"minimized $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.RESTORE)
"restore $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.HIDDEN)
"hidden $a"
Start-Sleep 2
$a = [WPIA.ConsoleUtils]::ShowWindow($hWnd, $ConsoleMode.SHOW)
"show $a"

There is a proper way to split the filename and the extension: Extract filename and extension in Bash

You can apply it like this:

date=$(date +"%m%d%y")
for FILE in folder1/*.csv
do
    bname=$(basename "$FILE")
    extension="${bname##*.}"
    filenamewoext="${bname%.*}"
    newfilename="${filenamewoext}${date}.${extension}
    cp folder1/${FILE} folder2/${newfilename}
done

You can use dblink to create a view that is resolved in another database. This database may be on another server.

I had tried many different solutions. This was the only one that worked for me in that it was able to pick up on styles applied at class level and at style as directly attributed on the element. So a font set at css file level and one as a style attribute; it returned the correct font.

It is simple! (Sorry, can't find where I originally found it)

//-- html object
var element = htmlObject; //e.g document.getElementById
//-- or jquery object
var element = htmlObject[0]; //e.g $(selector)

var stylearray = document.defaultView.getComputedStyle(element, null);
var font = stylearray["font-family"]

Alternatively you can list all the style by cycling through the array

for (var key in stylearray) {
console.log(key + ': ' + stylearray[key];
}

You can directly import github projects into Android Studio. File -> New -> Project from Version Control -> GitHub. Then enter your github username and password.Select the repository and hit clone.

The github repo will be created as a new project in android studio.

I often use a github starter project, like this (it uses babel)

Worth mentioning that the handlebar library https://github.com/jknack/handlebars.java can trivialize many transformation tasks include toCSV.

Purely compile time solution here. It's based on the fact that sizeof() of a string literal returns its length+1.

#define STRIPPATH(s)\
    (sizeof(s) > 2 && (s)[sizeof(s)-2] == '/' ? (s) + sizeof(s) - 1 : \
    sizeof(s) > 3 && (s)[sizeof(s)-3] == '/' ? (s) + sizeof(s) - 2 : \
    sizeof(s) > 4 && (s)[sizeof(s)-4] == '/' ? (s) + sizeof(s) - 3 : \
    sizeof(s) > 5 && (s)[sizeof(s)-5] == '/' ? (s) + sizeof(s) - 4 : \
    sizeof(s) > 6 && (s)[sizeof(s)-6] == '/' ? (s) + sizeof(s) - 5 : \
    sizeof(s) > 7 && (s)[sizeof(s)-7] == '/' ? (s) + sizeof(s) - 6 : \
    sizeof(s) > 8 && (s)[sizeof(s)-8] == '/' ? (s) + sizeof(s) - 7 : \
    sizeof(s) > 9 && (s)[sizeof(s)-9] == '/' ? (s) + sizeof(s) - 8 : \
    sizeof(s) > 10 && (s)[sizeof(s)-10] == '/' ? (s) + sizeof(s) - 9 : \
    sizeof(s) > 11 && (s)[sizeof(s)-11] == '/' ? (s) + sizeof(s) - 10 : (s))

#define __JUSTFILE__ STRIPPATH(__FILE__)

Feel free to extend the conditional operator cascade to the maximum sensible file name in the project. Path length doesn't matter, as long as you check far enough from the end of the string.

I'll see if I can get a similar macro with no hard-coded length with macro recursion...

You're calling writer.close(); after you've done writing to it. Once a stream is closed, it can not be written to again. Usually, the way I go about implementing this is by moving the close out of the write to method.

public void writeToFile(){
    String file_text= pedStatusText + "     " + gatesStatus + "     " + DrawBridgeStatusText;
    try {
        writer.write(file_text);
        writer.flush();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

And add a method cleanUp to close the stream.

public void cleanUp() {
     writer.close();
}

This means that you have the responsibility to make sure that you're calling cleanUp when you're done writing to the file. Failure to do this will result in memory leaks and resource locking.

EDIT: You can create a new stream each time you want to write to the file, by moving writer into the writeToFile() method..

 public void writeToFile() {
    FileWriter writer = new FileWriter("status.txt", true);
    // ... Write to the file.

    writer.close();
 }

DateTime tomorrow = DateTime.Today.AddDays(1);
DateTime yesterday = DateTime.Today.AddDays(-1);

Use a struct to simulate the data members of a class. In terms of method scope you can simulate private methods by placing the private function prototypes in the .c file and the public functions in the .h file.

Just load helper class

$this->load->helper('url');

thats it.

It is confirmed that Windows 7 and newer versions (at least 64bit or both) do not use system speaker and instead they route the call to the default sound device.

So, using system.beep() in win7/8/10 will not produce sound using internal system speaker. Instead, you'll get a beep sound from external speakers if they are available.

Here is a simple example:

    package main

    import "fmt"

    func plusTwo() (func(v int) (int)) {
        return func(v int) (int) {
            return v+2
        }
    }

    func plusX(x int) (func(v int) (int)) {
       return func(v int) (int) {
           return v+x
       }
    }

    func main() {
        p := plusTwo()
        fmt.Printf("3+2: %d\n", p(3))

        px := plusX(3)
        fmt.Printf("3+3: %d\n", px(3))
    }

Try svn export instead of svn checkout. That works for single files.

The reason for the limitation is that checkout creates a working copy, that contains meta-information about repository, revision, attributes, etc. That metadata is stored in subdirectories named '.svn'. And single files don't have subdirectories.

What this means is that you are trying to print out/output a value which is at least partially uninitialized. Can you narrow it down so that you know exactly what value that is? After that, trace through your code to see where it is being initialized. Chances are, you will see that it is not being fully initialized.

If you need more help, posting the relevant sections of source code might allow someone to offer more guidance.

EDIT

I see you've found the problem. Note that valgrind watches for Conditional jump or move based on unitialized variables. What that means is that it will only give out a warning if the execution of the program is altered due to the uninitialized value (ie. the program takes a different branch in an if statement, for example). Since the actual arithmetic did not involve a conditional jump or move, valgrind did not warn you of that. Instead, it propagated the "uninitialized" status to the result of the statement that used it.

It may seem counterintuitive that it does not warn you immediately, but as mark4o pointed out, it does this because uninitialized values get used in C all the time (examples: padding in structures, the realloc() call, etc.) so those warnings would not be very useful due to the false positive frequency.

From the YouTube help:

You will automatically be opted into showing ads on embedded videos if you've associated your YouTube and AdSense accounts and have enabled your videos for embedding.

If you don't want to show overlay ads on your embedded videos, you can opt your videos out of showing overlay ads, though this will also disable overlay ads on your videos on YouTube.com. You may also disable your videos for embedding.

https://support.google.com/youtube/answer/132596?hl=en

Another technical solution could be to use a custom video player, and streamline the youtube video with that one. Have not tried but guess that the ads cannot be displayed in a custom player. However, could be forbidden.

                }else if(v.getId()==2)
                {
                    txt_text.setText("how r u");

}

The LEFT OUTER JOIN will return all records from the LEFT table joined with the RIGHT table where possible.

If there are matches though, it will still return all rows that match, therefore, one row in LEFT that matches two rows in RIGHT will return as two ROWS, just like an INNER JOIN.

EDIT: In response to your edit, I've just had a further look at your query and it looks like you are only returning data from the LEFT table. Therefore, if you only want data from the LEFT table, and you only want one row returned for each row in the LEFT table, then you have no need to perform a JOIN at all and can just do a SELECT directly from the LEFT table.

Like you said since the xpath for the next button is the same on every page it won't work. It's working as coded in that it does wait for the element to be displayed but since it's already displayed then the implicit wait doesn't apply because it doesn't need to wait at all. Why don't you use the fact that the url changes since from your code it appears to change when the next button is clicked. I do C# but I guess in Java it would be something like:

WebDriver driver = new FirefoxDriver();
String startURL = //a starting url;
String currentURL = null;
WebDriverWait wait = new WebDriverWait(driver, 10);

foo(driver,startURL);

/* go to next page */
if(driver.findElement(By.xpath("//*[@id='someID']")).isDisplayed()){
    String previousURL = driver.getCurrentUrl();
    driver.findElement(By.xpath("//*[@id='someID']")).click();  
    driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);

    ExpectedCondition e = new ExpectedCondition<Boolean>() {
          public Boolean apply(WebDriver d) {
            return (d.getCurrentUrl() != previousURL);
          }
        };

    wait.until(e);
    currentURL = driver.getCurrentUrl();
    System.out.println(currentURL);
} 

On Centos, RedHat, Fedora and other yum-my systems it is much simpler than the PHP manual suggests:

yum install php-mbstring
service httpd restart

If you are using xampp 7.3.9. socket already installed. You can check xampp\php\ext and you will get the php_socket.dll. if you get it go to your xampp control panel open php.ini file and remove (;) from extension=sockets.

Just throwing another solution in the mix...

Try jq, a lightweight and flexible command-line JSON processor:

jq length /tmp/test.json

Prints the length of the array of objects.

Here's my implementation, which behaves exactly as item in list (at least on 2.3)

res/layout/list_video_footer.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/list_video_footer"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:background="@android:drawable/list_selector_background"
        android:clickable="true"
        android:gravity="center"
        android:minHeight="98px"
        android:text="@string/more"
        android:textColor="@color/bright_text_dark_focused"
        android:textSize="18dp"
        android:textStyle="bold" />

</FrameLayout>

res/color/bright_text_dark_focused.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_selected="true" android:color="#444"/>
    <item android:state_focused="true" android:color="#444"/>
    <item android:state_pressed="true" android:color="#444"/>
    <item android:color="#ccc"/>

</selector>

Just add target="_blank" to the

<a mat-raised-button target="_blank" [routerLink]="['/find-post/post', post.postID]"
    class="theme-btn bg-grey white-text mx-2 mb-2">
    Open in New Window
</a>

The easiest way

import re

txt='this is a paragraph with<[1> in between</[1> and then there are cases ... where the<[99> number ranges from 1-100</[99>.  and there are many other lines in the txt files with<[3> such tags </[3>'

out = re.sub("(<[^>]+>)", '', txt)
print out

I use this powershell oneliner:

gci C:\`$recycle.bin -force | remove-item -recurse -force

Works for different drives than C:, too

DateTime values should be inserted as if they are strings surrounded by single quotes:

'20100301'

SQL Server allows for many accepted date formats and it should be the case that most development libraries provide a series of classes or functions to insert datetime values properly. However, if you are doing it manually, it is important to distinguish the date format using DateFormat and to use generalized format:

Set DateFormat MDY --indicates the general format is Month Day Year

Insert Table( DateTImeCol )
Values( '2011-03-12' )

By setting the dateformat, SQL Server now assumes that my format is YYYY-MM-DD instead of YYYY-DD-MM.

SET DATEFORMAT

SQL Server also recognizes a generic format that is always interpreted the same way: YYYYMMDD e.g. 20110312.

If you are asking how to insert the current date and time using T-SQL, then I would recommend using the keyword CURRENT_TIMESTAMP. For example:

Insert Table( DateTimeCol )
Values( CURRENT_TIMESTAMP )

I ran this on MacOS /Applications/Python\ 3.6/Install\ Certificates.command

Possibly use something like firefox's tamperdata and look at the header returned (if they have publishing enabled).

This is an easy and fast way to export a table to a script with pgAdmin manually without extra installations:

1. Right click on target table and select "Backup".
2. Select a file path to store the backup. As Format choose "Plain".
3. Open the tab "Dump Options #2" at the bottom and check "Use Column Inserts".
4. Click the Backup-button.
5. If you open the resulting file with a text reader (e.g. notepad++) you get a script to create the whole table. From there you can simply copy the generated INSERT-Statements.

This method also works with the technique of making an export_table as demonstrated in @Clodoaldo Neto's answer.

Modified Murtaza Hussain answer:

function unserializeForm($str) {
    $strArray = explode("&", $str);
    foreach($strArray as $item) {
        $array = explode("=", $item);
        $returndata[] = $array;
    }
    return $returndata;
}

In my case, it was a misconfigured IntelliJ instance.

Project Structure -> SDKs -> Remove and add the Java SDK again

use this formula to convert a pandas DataFrame to a list of dictionaries :

import json
json_list = json.loads(json.dumps(list(DataFrame.T.to_dict().values())))

Just to elucidate a bit on @emsr's comment in @unwind's answer, if one is not fortunate enough to have a C++11 compiler (say GCC 4.2.1), and one wants to embed the newlines in the string (either char * or class string), one can write something like this:

const char *text =
  "This text is pretty long, but will be\n"
  "concatenated into just a single string.\n"
  "The disadvantage is that you have to quote\n"
  "each part, and newlines must be literal as\n"
  "usual.";

Very obvious, true, but @emsr's short comment didn't jump out at me when I read this the first time, so I had to discover this for myself. Hopefully, I've saved someone else a few minutes.

You can simply add multiple conditions by adding them as where() inside the join closure

->leftJoin('table2 AS b', function($join){
        $join->on('a.field1', '=', 'b.field2')
        ->where('b.field3', '=', true)
        ->where('b.field4', '=', '1');
})

<?php 
$connection = mysqli_connect("localhost","root","","php_sample_login_register"); 

if ($connection){
        echo "DB is Connected <br>";
        $sql = "CREATE TABLE user(
            id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY, 
            name VARCHAR(255)NOT NULL,
            email VARCHAR(255)NOT NULL,
            password VARCHAR(255) NOT NULL
            );";
        if(mysqli_query($connection,$sql)) {
            echo "Created user table";
        } else{
            echo "User table already exists";
        }
    } else {
        echo "error : DB isnot connected";
    } ?>

You can instantiate it after you implemented all the methods. Then the constructor will be called.

Simplistic. So very normal looking, its almost comforting:

var userName = "Sean";

console.log(name());

function name() {
  return userName;
}

However, what if I include a really handy javascript library to my page that translates advanced characters into their base level representations?

Wait... what?

I mean, if someone types in a character with some kind of accent on it, but I only want 'English' characters A-Z in my program? Well... the Spanish 'ñ' and French 'é' characters can be translated into base characters of 'n' and 'e'.

So someone nice person has written a comprehensive character converter out there that I can include in my site... I include it.

One problem: it has a function in it called 'name' same as my function.

This is what's called collision. We've got two functions declared in the same scope with the same name. We want to avoid this.

So we need to scope our code somehow.

The only way to scope code in javascript is to wrap it in a function:

function main() {
  // We are now in our own sound-proofed room and the 
  // character-converter libarary's name() function can exist at the 
  // same time as ours. 

  var userName = "Sean";

  console.log(name());

  function name() {
    return userName;
  }
}

That might solve our problem. Everything is now enclosed and can only be accessed from within our opening and closing braces.

We have a function in a function... which is weird to look at, but totally legal.

Only one problem. Our code doesn't work. Our userName variable is never echoed into the console!

We can solve this issue by adding a call to our function after our existing code block...

function main() {
  // We are now in our own sound-proofed room and the 
  // character-converter libarary's name() function can exist at the 
  // same time as ours. 

  var userName = "Sean";

  console.log(name());

  function name() {
    return userName;
  }
}

main();

Or before!

main();

function main() {
  // We are now in our own sound-proofed room and the 
  // character-converter libarary's name() function can exist at the 
  // same time as ours. 

  var userName = "Sean";

  console.log(name());

  function name() {
    return userName;
  }
}

A secondary concern: What are the chances that the name 'main' hasn't been used yet? ...so very, very slim.

We need MORE scoping. And some way to automatically execute our main() function.

Now we come to auto-execution functions (or self-executing, self-running, whatever).

((){})();

The syntax is awkward as sin. However, it works.

When you wrap a function definition in parentheses, and include a parameter list (another set or parentheses!) it acts as a function call.

So lets look at our code again, with some self-executing syntax:

(function main() {
  var userName = "Sean";

    console.log(name());

    function name() {
      return userName;
    }
  }
)();

So, in most tutorials you read, you will now be bombard with the term 'anonymous self-executing' or something similar.

After many years of professional development, I strongly urge you to name every function you write for debugging purposes.

When something goes wrong (and it will), you will be checking the backtrace in your browser. It is always easier to narrow your code issues when the entries in the stack trace have names!

Hugely long-winded and I hope it helps!

With Guava, you can use Iterables.concat(Iterable<T> ...), it creates a live view of all the iterables, concatenated into one (if you change the iterables, the concatenated version also changes). Then wrap the concatenated iterable with Iterables.unmodifiableIterable(Iterable<T>) (I hadn't seen the read-only requirement earlier).

From the Iterables.concat( .. ) JavaDocs:

Combines multiple iterables into a single iterable. The returned iterable has an iterator that traverses the elements of each iterable in inputs. The input iterators are not polled until necessary. The returned iterable's iterator supports remove() when the corresponding input iterator supports it.

While this doesn't explicitly say that this is a live view, the last sentence implies that it is (supporting the Iterator.remove() method only if the backing iterator supports it is not possible unless using a live view)

Sample Code:

final List<Integer> first  = Lists.newArrayList(1, 2, 3);
final List<Integer> second = Lists.newArrayList(4, 5, 6);
final List<Integer> third  = Lists.newArrayList(7, 8, 9);
final Iterable<Integer> all =
    Iterables.unmodifiableIterable(
        Iterables.concat(first, second, third));
System.out.println(all);
third.add(9999999);
System.out.println(all);

Output:

[1, 2, 3, 4, 5, 6, 7, 8, 9]
[1, 2, 3, 4, 5, 6, 7, 8, 9, 9999999]

Edit:

By Request from Damian, here's a similar method that returns a live Collection View

public final class CollectionsX {

    static class JoinedCollectionView<E> implements Collection<E> {

        private final Collection<? extends E>[] items;

        public JoinedCollectionView(final Collection<? extends E>[] items) {
            this.items = items;
        }

        @Override
        public boolean addAll(final Collection<? extends E> c) {
            throw new UnsupportedOperationException();
        }

        @Override
        public void clear() {
            for (final Collection<? extends E> coll : items) {
                coll.clear();
            }
        }

        @Override
        public boolean contains(final Object o) {
            throw new UnsupportedOperationException();
        }

        @Override
        public boolean containsAll(final Collection<?> c) {
            throw new UnsupportedOperationException();
        }

        @Override
        public boolean isEmpty() {
            return !iterator().hasNext();
        }

        @Override
        public Iterator<E> iterator() {
            return Iterables.concat(items).iterator();
        }

        @Override
        public boolean remove(final Object o) {
            throw new UnsupportedOperationException();
        }

        @Override
        public boolean removeAll(final Collection<?> c) {
            throw new UnsupportedOperationException();
        }

        @Override
        public boolean retainAll(final Collection<?> c) {
            throw new UnsupportedOperationException();
        }

        @Override
        public int size() {
            int ct = 0;
            for (final Collection<? extends E> coll : items) {
                ct += coll.size();
            }
            return ct;
        }

        @Override
        public Object[] toArray() {
            throw new UnsupportedOperationException();
        }

        @Override
        public <T> T[] toArray(T[] a) {
            throw new UnsupportedOperationException();
        }

        @Override
        public boolean add(E e) {
            throw new UnsupportedOperationException();
        }

    }

Recently I bumped into a local company's Notes 6.5 system and found out the webmail would show unidentifiable characters on a non-Zhongwen localed Windows installation. Have dug for several weeks online, figured it out just few minutes ago:

In Java properties, add the following string to Runtime Parameters

-Dfile.encoding=MS950 -Duser.language=zh -Duser.country=TW -Dsun.jnu.encoding=MS950

UTF-8 setting would not work in this case.

<div class="container">
    <div class="row">
       <div class="col-xs-6 col-sm-6 col-md-6">
          First Div
       </div>
       <div class="col-xs-6 col-sm-6 col-md-6">
          Second Div
       </div>
   </div>

This does the trick.

node-mysql is probably one of the best modules out there used for working with MySQL database which is actively maintained and well documented.

The actual cause of this warning is that you have configured your project to run with an earlier JRE version then you have installed. Generally this occurs whenever you use old projects with newer JREs.

This will likely cause no trouble at all. But if you want to be really on the save side, you should install the correct, old JDK. You can find them here: http://www.oracle.com/technetwork/java/archive-139210.html

If you then restart eclipse you can go into Window > Preferences > Java > Installed JREs > Execution Environments and set for in your case J2SE-1.4 the [perfect match] as eclipse calls it.

Those are "non-client" areas and are controlled by Windows. Here is the MSDN docs on the subject (the pertinent info is at the top).

Basically, you set your Window's WindowStyle="None", then build your own window interface. (similar question on SO)

On openSUSE you need to install the packages openldap2-devel, cyrus-sasl-devel, python-devel and libopenssl-devel.

I got the answer for the same , Go on SQL Server ? Tools ? Options ? Designers ? Table and Database Designers and unselect Prevent saving changes that require table re-creation

2- Open table design view and that scroll your column up and down and save your changes.

To make this work on Ubuntu Linux:

1. I installed the Ubuntu package ruby-json:

   apt-get install ruby-json
   

2. I wrote the script in ${HOME}/rubybin/jsonDEMO

3. $HOME/.bashrc included:

   ${HOME}/rubybin:${PATH}
   

(On this occasion I also typed the above on the bash command line.)

Then it worked when I entered on the command line:

jsonDemo

select CASE 
when exists (SELECT U.USERID,U.USERNAME,U.PASSWORDHASH
FROM  TBLUSERS U WHERE U.USERID =U.USERID 
AND U.PASSWORDHASH=U.PASSWORDHASH) 
then 'OLD PASSWORD EXISTS' 
else 'OLD PASSWORD NOT EXISTS' 
end as OUTPUT
from DUAL;

System.Windows.Forms.Application.StartupPath will solve your problem, I think

The theoretical limit may be 2,147,483,647, but the practical limit is nowhere near that. Since no single object in a .NET program may be over 2GB and the string type uses UTF-16 (2 bytes for each character), the best you could do is 1,073,741,823, but you're not likely to ever be able to allocate that on a 32-bit machine.

This is one of those situations where "If you have to ask, you're probably doing something wrong."

datetime.datetime.fromtimestamp() is correct, except you are probably having timestamp in miliseconds (like in JavaScript), but fromtimestamp() expects Unix timestamp, in seconds.

Do it like that:

>>> import datetime
>>> your_timestamp = 1331856000000
>>> date = datetime.datetime.fromtimestamp(your_timestamp / 1e3)

and the result is:

>>> date
datetime.datetime(2012, 3, 16, 1, 0)

Does it answer your question?

EDIT: J.F. Sebastian correctly suggested to use true division by 1e3 (float 1000). The difference is significant, if you would like to get precise results, thus I changed my answer. The difference results from the default behaviour of Python 2.x, which always returns int when dividing (using / operator) int by int (this is called floor division). By replacing the divisor 1000 (being an int) with the 1e3 divisor (being representation of 1000 as float) or with float(1000) (or 1000. etc.), the division becomes true division. Python 2.x returns float when dividing int by float, float by int, float by float etc. And when there is some fractional part in the timestamp passed to fromtimestamp() method, this method's result also contains information about that fractional part (as the number of microseconds).

Just a small correction to the first answer in this thread.

Even for Stack, you need to create new object with generics if you are using Stack from java util packages.

Right usage:
    Stack<Integer> s = new Stack<Integer>();
    Stack<String> s1 = new Stack<String>();

    s.push(7);
    s.push(50);

    s1.push("string");
    s1.push("stack");

if used otherwise, as mentioned in above post, which is:

    /*
    Stack myStack = new Stack();
    // add any type of elements (String, int, etc..)
    myStack.push("Hello");
    myStack.push(1);
    */

Although this code works fine, has unsafe or unchecked operations which results in error.

you can do update the User path as inside _JAVA_OPTIONS : -Xmx512M Path : C:\Program Files (x86)\Java\jdk1.8.0_231\bin;C:\Program Files(x86)\Java\jdk1.8.0_231\jre\bin for now it is working / /

Say we have two date select fields, field1, and field2. field2 date depends on field1

$('#field2').datepicker();
$('#field1').datepicker({
  onSelect: function(dateText, inst) {
    $('#field2').val("");
    $('#field2').datepicker("option", "minDate", new Date(dateText));
  }
});

This query should give you result equivalent to trunc(sysdate) in Oracle.

SELECT  * 
FROM    your_table
WHERE   CONVERT(varchar(12), your_column_name, 101)
      = CONVERT(varchar(12), GETDATE(), 101)

Hope this helps!

Comments work fine in any of the usual Java/Groovy forms, but you can't currently use groovydoc to process your Jenkinsfile (s).

First, groovydoc chokes on files without extensions with the wonderful error

... and second, as far as I can tell Javadoc-style commments at the start of a groovy script are ignored. So even if you copy/rename your Jenkinsfile to Jenkinsfile.groovy, you won't get much useful output.

I want to be able to use a

groovydoc will process classes and methods defined in your Jenkinsfile if you pass -private to the command, though.

Is there a way to get a list of all the keys in a Go language map?

how do I iterate over all the keys?

Use the accepted answer:

With Respect to .NET Framework 4.6 and Visual Studio 2017 you can take the below steps:

1. On the option bar at the top of visual studio, select the 4th option "Project" and under that click on the last option which says [ProjectName]Properties.Click on it & you shall see a new tab has been opened.Under that select the Application option on the left and you will see the .NET Framework version by the name "Target Framework".
2. Under Solution Explorer's tab select your project and press Alt + Enter.
3. OR simply Right-click on your project and click on the last option which says Properties.

The problem I had accessing the sqlite db file I created in my java (jersey) server had solely to due with path. Some of the docs say the jdbc connect url should look like "jdbc:sqlite://path-to-file/sample.db". I thought the double-slash was part of a htt protocol-style path and would map properly when deployed, but in actuality, it's an absolute or relative path. So, when I placed the file at the root of the WebContent folder (tomcat project), a uri like this worked "jdbc:sqlite:sample.db".

The one thing that was throwing me was that when I was stepping through the debugger, I received a message that said "opening db: ... permission denied". I thought it was a matter of file system permissions or perhaps sql user permissions. After finding out that SQLite doesn't have the concept of roles/permissions like MySQL, etc, I did eventually change the file permissions before I came to what I believe was the correct solution, but I think it was just a bad message (i.e. permission denied, instead of File not found).

Hope this helps someone.

Pointing to Best Practices for Using Strings in the .NET Framework:

• Use StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase for comparisons as your safe default for culture-agnostic string matching.
• Use comparisons with StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase for better performance.
• Use the non-linguistic StringComparison.Ordinal or StringComparison.OrdinalIgnoreCase values instead of string operations based on CultureInfo.InvariantCulture when the comparison is linguistically irrelevant (symbolic, for example).

And finally:

• Do not use string operations based on StringComparison.InvariantCulture in most cases. One of the few exceptions is when you are persisting linguistically meaningful but culturally agnostic data.

I am posting this answer so the topmost answer (when sorted by activity) is not one that is just plain wrong.

What is a Stacktrace?

A stacktrace is a very helpful debugging tool. It shows the call stack (meaning, the stack of functions that were called up to that point) at the time an uncaught exception was thrown (or the time the stacktrace was generated manually). This is very useful because it doesn't only show you where the error happened, but also how the program ended up in that place of the code. This leads over to the next question:

What is an Exception?

An Exception is what the runtime environment uses to tell you that an error occurred. Popular examples are NullPointerException, IndexOutOfBoundsException or ArithmeticException. Each of these are caused when you try to do something that is not possible. For example, a NullPointerException will be thrown when you try to dereference a Null-object:

Object a = null;
a.toString();                 //this line throws a NullPointerException

Object[] b = new Object[5];
System.out.println(b[10]);    //this line throws an IndexOutOfBoundsException,
                              //because b is only 5 elements long
int ia = 5;
int ib = 0;
ia = ia/ib;                   //this line throws an  ArithmeticException with the 
                              //message "/ by 0", because you are trying to
                              //divide by 0, which is not possible.

How should I deal with Stacktraces/Exceptions?

At first, find out what is causing the Exception. Try googleing the name of the exception to find out, what is the cause of that exception. Most of the time it will be caused by incorrect code. In the given examples above, all of the exceptions are caused by incorrect code. So for the NullPointerException example you could make sure that a is never null at that time. You could, for example, initialise a or include a check like this one:

if (a!=null) {
    a.toString();
}

This way, the offending line is not executed if a==null. Same goes for the other examples.

Sometimes you can't make sure that you don't get an exception. For example, if you are using a network connection in your program, you cannot stop the computer from loosing it's internet connection (e.g. you can't stop the user from disconnecting the computer's network connection). In this case the network library will probably throw an exception. Now you should catch the exception and handle it. This means, in the example with the network connection, you should try to reopen the connection or notify the user or something like that. Also, whenever you use catch, always catch only the exception you want to catch, do not use broad catch statements like catch (Exception e) that would catch all exceptions. This is very important, because otherwise you might accidentally catch the wrong exception and react in the wrong way.

try {
    Socket x = new Socket("1.1.1.1", 6789);
    x.getInputStream().read()
} catch (IOException e) {
    System.err.println("Connection could not be established, please try again later!")
}

Why should I not use catch (Exception e)?

Let's use a small example to show why you should not just catch all exceptions:

int mult(Integer a,Integer b) {
    try {
        int result = a/b
        return result;
    } catch (Exception e) {
        System.err.println("Error: Division by zero!");
        return 0;
    }
}

What this code is trying to do is to catch the ArithmeticException caused by a possible division by 0. But it also catches a possible NullPointerException that is thrown if a or b are null. This means, you might get a NullPointerException but you'll treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.

TLDR

1. Figure out what is the cause of the exception and fix it, so that it doesn't throw the exception at all.

2. If 1. is not possible, catch the specific exception and handle it.

   • Never just add a try/catch and then just ignore the exception! Don't do that!
   • Never use catch (Exception e), always catch specific Exceptions. That will save you a lot of headaches.

If you're using SQL Server 2005 or above, you can use the windowing function SUM() OVER ().

case 
when test1.TotalType = 'Average' then Test2.avgscore
when test1.TotalType = 'PercentOfTot' then (cnt/SUM(test1.qrank) over ())
else cnt
end as displayscore

But it'll be better if you show your full query to get context of what you actually need.

    console.log(event.target.value);
};

I've had this error message show up, for completely unrelated reasons to the flags 0 or 1 mentionned in the other answers. You might be seeing it too because cv2.imread will not error out if the path string you pass it is not an image:

In [1]: import cv2
   ...: img = cv2.imread('asdfasdf')  # This is clearly not an image file
   ...: gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
   ...:

OpenCV Error: Assertion failed (scn == 3 || scn == 4) in cv::cvtColor, file C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp, line 10638
---------------------------------------------------------------------------

      1 import cv2
      2 img = cv2.imread('asdfasdf')  # This is clearly not an image file
----> 3 gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

error: C:\projects\opencv-python\opencv\modules\imgproc\src\color.cpp:10638: error: (-215) scn == 3 || scn == 4 in function cv::cvtColor

So you're seeing a cvtColor failure when it's in fact a silent imread error. Keep that in mind next time you go wasting an hour of your life with that cryptic metaphor.

Solution

You might need to check that your path string represents a valid file before passing it to cv2.imread:

import os


def read_img(path):
    """Given a path to an image file, returns a cv2 array

    str -> np.ndarray"""
    if os.path.isfile(path):
        return cv2.imread(path)
    else:
        raise ValueError('Path provided is not a valid file: {}'.format(path))


path = '2015-05-27-191152.jpg'
img = read_img(path)
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

Written this way, your code will fail gracefully.

Great question: How does our differ from my and what does our do?

In Summary:

Available since Perl 5, my is a way to declare non-package variables, that are:

• private
• new
• non-global
• separate from any package, so that the variable cannot be accessed in the form of $package_name::variable.

On the other hand, our variables are package variables, and thus automatically:

• global variables
• definitely not private
• not necessarily new
• can be accessed outside the package (or lexical scope) with the qualified namespace, as $package_name::variable.

Declaring a variable with our allows you to predeclare variables in order to use them under use strict without getting typo warnings or compile-time errors. Since Perl 5.6, it has replaced the obsolete use vars, which was only file-scoped, and not lexically scoped as is our.

For example, the formal, qualified name for variable $x inside package main is $main::x. Declaring our $x allows you to use the bare $x variable without penalty (i.e., without a resulting error), in the scope of the declaration, when the script uses use strict or use strict "vars". The scope might be one, or two, or more packages, or one small block.

Adding a service reference allows you to create a WCF client, which can be used to talk to a regular web service provided you use the appropriate binding. Adding a web reference will allow you to create only a web service (i.e., SOAP) reference.

If you are absolutely certain you are not ready for WCF (really don't know why) then you should create a regular web service reference.

In addition mysql passwords when not using the IDENTIFIED BY clause, may be blank values, if non-blank, they may be encrypted. But yes USAGE is used to modify an account by granting simple resource limiters such as MAX_QUERIES_PER_HOUR, again this can be specified by also using the WITH clause, in conjuction with GRANT USAGE(no privileges added) or GRANT ALL, you can also specify GRANT USAGE at the global level, database level, table level,etc....

Your code would be like this:

int *p = (int *)0x28ff44;

int needs to be the type of the object that you are referencing or it can be void.

But be careful so that you don't try to access something that doesn't belong to your program.

I wrote a simple jQuery plugin that will do what you are looking for.

https://github.com/afklondon/jquery.inactivity

$(document).inactivity( {
    interval: 1000, // the timeout until the inactivity event fire [default: 3000]
    mouse: true, // listen for mouse inactivity [default: true]
    keyboard: false, // listen for keyboard inactivity [default: true]
    touch: false, // listen for touch inactivity [default: true]
    customEvents: "customEventName", // listen for custom events [default: ""]
    triggerAll: true, // if set to false only the first "activity" event will be fired [default: false]
});

The script will listen for mouse, keyboard, touch and other custom events inactivity (idle) and fire global "activity" and "inactivity" events.

Hope this helps :)

Doesn't look like you are using the correct overload of ActionLink. Try this:-

<%=Html.ActionLink("Modify Villa", "Modify", new {id = "1"})%>

This assumes your view is under the /Views/Villa folder. If not then I suspect you need:-

<%=Html.ActionLink("Modify Villa", "Modify", "Villa", new {id = "1"}, null)%>

int processed = 0;
foreach(ListViewItem lvi in listView.Items)
{
   //do stuff
   if (++processed == 50) break;
}

or use LINQ

foreach( ListViewItem lvi in listView.Items.Cast<ListViewItem>().Take(50))
{
    //do stuff
}

or just use a regular for loop (as suggested by @sgriffinusa and @Eric J.)

for(int i = 0; i < 50 && i < listView.Items.Count; i++)
{
    ListViewItem lvi = listView.Items[i];
}

I got this problem after moving a large solution from one folder in Source Control Explorer to another. We don't check the package folder into Team Foundation and so I think VS downloaded packages automatically. This upgraded my EF form v6.1.2 to v6.1.3.

The problem went away when I downgraded to the original v6.1.2.

 )

  AS
  BEGIN

  -- Here we have some opereations

 -- If there is any Error Before Executing SP2 then SP will stop executing.

  Exec SP2 @ID,@Name,@SomeID OUTPUT 

 -- ,etc some other parameter also we can use OutPut parameters like 

 -- @SomeID is useful for some other operations for condition checking insertion etc.

 -- If you have any Error in you SP2 then also it will stop executing.

Following is the DP based solution for Edit Distance problem which is top down. I hope it will also help in understanding the world of Dynamic Programming:

         int m = word2.length();
            int n = word1.length();


     if(m == 0) // Cannot miss the corner cases !
                return n;
        if(n == 0)
            return m;
        int[][] DP = new int[n + 1][m + 1];

        for(int j =1 ; j <= m; j++) {
            DP[0][j] = j;
        }
        for(int i =1 ; i <= n; i++) {
            DP[i][0] = i;
        }

        for(int i =1 ; i <= n; i++) {
            for(int j =1 ; j <= m; j++) {

When declaring React Class component, use React.ComponentClass instead of React.Component then it will fix the ts error.

I realise this is only applicable to a niche of the situations, but within a numpy context I really like using np.errstate:

np.sqrt(-1)

__main__:1: RuntimeWarning: invalid value encountered in sqrt
nan

However, using np.errstate:

with np.errstate(invalid='ignore'):
    np.sqrt(-1)

nan

The best part being you can apply this to very specific lines of code only.

If anyone wants the true solution for centering BOTH images and text within a span using bootstrap row-fluid, here it is (how to implement this and explanation follows my example):

css

div.row-fluid [class*="span"] .center-in-span { 
   float: none; 
   margin: 0 auto; 
   text-align: center; 
   display: block; 
   width: auto; 
   height: auto;
}

html

<div class="row-fluid">
   <div class="span12">
      <img class="center-in-span" alt="MyExample" src="/path/to/example.jpg"/>
   </div>
</div>

<div class="row-fluid">
   <div class="span12">
      <p class="center-in-span">this is text</p>
   </div>
</div>

USAGE: To use this css to center an image within a span, simply apply the .center-in-span class to the img element, as shown above.

To use this css to center text within a span, simply apply the .center-in-span class to the p element, as shown above.

EXPLANATION: This css works because we are overriding specific bootstrap styling. The notable differences from the other answers that were posted are that the width and height are set to auto, so you don't have to used a fixed with (good for a dynamic webpage). also, the combination of setting the margin to auto, text-align:center and display:block, takes care of both images and paragraphs.

Let me know if this is thorough enough for easy implementation.

As several folks have noted, requests doesn't support FTP but Python has other libraries that do. If you want to keep using the requests library, there is a requests-ftp package that adds FTP capability to requests. I've used this library a little and it does work. The docs are full of warnings about code quality though. As of 0.2.0 the docs say "This library was cowboyed together in about 4 hours of total work, has no tests, and relies on a few ugly hacks".

import requests, requests_ftp
requests_ftp.monkeypatch_session()
response = requests.get('ftp://example.com/foo.txt')

If the problem still persists even after putting the after build in the correct project try using "copy" instead of xcopy. This worked for me.

You can install any current version of Anaconda. You can then make a conda environment with your particular needs from the documentation

conda create -n tensorflowproject python=3.5 tensorflow ipython

This command has a specific version for python and when this tensorflowproject environment gets updated it will upgrade to Python 3.5999999999 but never go to 3.6 . Then you switch to your environment using either

source activate tensorflowproject

for linux/mac or

activate tensorflowproject

on windows

    function addToUrl($url, $key, $value = null) {

If you must, this is how you can do it in a for loop:

mylist = ['first', 'second', 'other']
endstring = ''
for s in mylist:
  endstring += s

but you should consider using join():

''.join(mylist)

You need this include:

#include <sstream>

just a convenient way of getting last n=5 containers (no matter running or not):

$ docker container ls -a -n5

This worked for me:

openssl s_client -help 2>&1  > /dev/null | egrep "\-(ssl|tls)[^a-z]"

Please let me know if this is wrong.

I would like to add a 3rd Scenario

The moving position is not saved in any way. Think of it as a mouse movement - your cursor is not a React-component, right?

All you do, is to add a prop like "draggable" to your component and a stream of the dragging events that will manipulate the dom.

setXandY: function(event) {
    // DOM Manipulation of x and y on your node
},

componentDidMount: function() {
    if(this.props.draggable) {
        var node = this.getDOMNode();
        dragStream(node).onValue(this.setXandY);  //baconjs stream
    };
},

In this case, a DOM manipulation is an elegant thing (I never thought I'd say this)

Here is a tidyverse option that might not the most elegant, but offers some flexibility in terms of what is included in the summary:

library(tidyverse)
dir_path <- '~/path/to/data/directory/'
file_pattern <- 'Df\\.[0-9]\\.csv' # regex pattern to match the file name format

read_dir <- function(dir_path, file_name){
  read_csv(paste0(dir_path, file_name)) %>% 
    mutate(file_name = file_name) %>%                # add the file name as a column              
    gather(variable, value, A:B) %>%                 # convert the data from wide to long
    group_by(file_name, variable) %>% 
    summarize(sum = sum(value, na.rm = TRUE),
              min = min(value, na.rm = TRUE),
              mean = mean(value, na.rm = TRUE),
              median = median(value, na.rm = TRUE),
              max = max(value, na.rm = TRUE))
  }

df_summary <- 
  list.files(dir_path, pattern = file_pattern) %>% 
  map_df(~ read_dir(dir_path, .))

df_summary
# A tibble: 8 x 7
# Groups:   file_name [?]
  file_name variable   sum   min  mean median   max
  <chr>     <chr>    <int> <dbl> <dbl>  <dbl> <dbl>
1 Df.1.csv  A           34     4  5.67    5.5     8
2 Df.1.csv  B           22     1  3.67    3       9
3 Df.2.csv  A           21     1  3.5     3.5     6
4 Df.2.csv  B           16     1  2.67    2.5     5
5 Df.3.csv  A           30     0  5       5      11
6 Df.3.csv  B           43     1  7.17    6.5    15
7 Df.4.csv  A           21     0  3.5     3       8
8 Df.4.csv  B           42     1  7       6      16

Easiest way: select the TARGET name, double click on it, rename. You'll see your app's new name underneath the icon on your device or Simulator.

It is very simple. You can use

.fill .map 
{
  min-height: 100vh;
}

You can change height according to your requirement.

Try this:

$("#textbox").bind('paste',function() {alert("Change detected!");});

See demo on JSFiddle.

On an inner join, they mean the same thing. However you will get different results in an outer join depending on if you put the join condition in the WHERE vs the ON clause. Take a look at this related question and this answer (by me).

I think it makes the most sense to be in the habit of always putting the join condition in the ON clause (unless it is an outer join and you actually do want it in the where clause) as it makes it clearer to anyone reading your query what conditions the tables are being joined on, and also it helps prevent the WHERE clause from being dozens of lines long.

Rom, you're doing it wrong. You don't want to write files to disk so that IIS can serve them up. That adds security implications as well as increases complexity. All you really need to do is save the CSV directly to the response stream.

Here's the scenario: User wishes to download csv. User submits a form with details about the csv they want. You prepare the csv, then provide the user a URL to an aspx page which can be used to construct the csv file and write it to the response stream. The user clicks the link. The aspx page is blank; in the page codebehind you simply write the csv to the response stream and end it.

You can add the following to the (I believe this is correct) Load event:

string attachment = "attachment; filename=MyCsvLol.csv";
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ClearHeaders();
HttpContext.Current.Response.ClearContent();
HttpContext.Current.Response.AddHeader("content-disposition", attachment);
HttpContext.Current.Response.ContentType = "text/csv";
HttpContext.Current.Response.AddHeader("Pragma", "public");

var sb = new StringBuilder();
foreach(var line in DataToExportToCSV)
  sb.AppendLine(TransformDataLineIntoCsv(line));

HttpContext.Current.Response.Write(sb.ToString());

writing to the response stream code ganked from here.

I think programmers should be competent in the language they are using; use it clearly; and use it well. I don't think they should artificially cripple the language they are using. I speak from experience. I once worked literally next door to a Cobol shop where they didn't use ELSE 'because it was too complicated'. Reductio ad absurdam.

The correct pattern is to call the Redirect overload with endResponse=false and make a call to tell the IIS pipeline that it should advance directly to the EndRequest stage once you return control:

Response.Redirect(url, false);
Context.ApplicationInstance.CompleteRequest();

This blog post from Thomas Marquardt provides additional details, including how to handle the special case of redirecting inside an Application_Error handler.

Marker already has unique id

marker.__gm_id

It also has a syntax similar to prinft, e.g.:

qDebug ("message %d, says: %s",num,str); 

Very handy as well

I'll offer an oddball alternative. Sometimes it's easier to use different encoding, especially if you're dealing with a variety of systems that don't all handle the details of URL encoding the same way. This isn't the most mainstream approach but can come in handy in certain situations.

Rather than URL-encoding the data, you can base64-encode it. The benefit of this is the encoded data is very generic, consisting only of alpha characters and sometimes trailing ='s. Example:

JSON array-of-strings:

["option", "Fred's dog", "Bill & Trudy", "param=3"]

That data, URL-encoded as the data param:

"data=%5B%27option%27%2C+%22Fred%27s+dog%22%2C+%27Bill+%26+Trudy%27%2C+%27param%3D3%27%5D"

Same, base64-encoded:

"data=WyJvcHRpb24iLCAiRnJlZCdzIGRvZyIsICJCaWxsICYgVHJ1ZHkiLCAicGFyYW09MyJd"

The base64 approach can be a bit shorter, but more importantly it's simpler. I often have problems moving URL-encoded data between cURL, web browsers and other clients, usually due to quotes, embedded % signs and so on. Base64 is very neutral because it doesn't use special characters.

If the above solution didn't work and you got any unhandled promise rejection then try to follow steps :

1. Clean the Cordova project

   cordova clean

   2. Remove platform

cordova platform remove android/ios

3. Then remove plugin

cordova plugin remove

4. add platforms and run the project It worked for me.

I was looking for a way to disable my already existing DataGridView and came across several answers. Oddly enough, the first few results on google were some very old topics. This being the earliest one of them, I decide to put my answer here.

private void dgvDetails_ColumnStateChanged(object sender, DataGridViewColumnStateChangedEventArgs e)
{
    e.Column.SortMode = DataGridViewColumnSortMode.NotSortable;
}

The description when you click on ColumStateChanged in the properties window is:

"Occurs when a column changes state, such as gaining or loosing focus"

Granted there are many ways to do this but I thought I'd add this one here. Can't say I found it anywhere else but then again I only read the first 5 topics I found.

REST is just a software architecture style for exposing resources.

• Use HTTP methods explicitly.
• Be stateless.
• Expose directory structure-like URIs.
• Transfer XML, JavaScript Object Notation (JSON), or both.

A typical REST call to return information about customer 34456 could look like:

http://example.com/customer/34456

Have a look at the IBM tutorial for REST web services

There are tons of sample code online as to how to do this.

Here is just one example of how to do this: http://geekswithblogs.net/dotNETvinz/archive/2009/04/30/creating-a-simple-registration-form-in-asp.net.aspx

you define the text boxes between the following tag:

<form id="form1" runat="server"> 

you create your textboxes and define them to runat="server" like so:

<asp:TextBox ID="TxtName" runat="server"></asp:TextBox>

define a button to process your logic like so (notice the onclick):

<asp:Button ID="Button1" runat="server" Text="Save" onclick="Button1_Click" />

in the code behind, you define what you want the server to do if the user clicks on the button by defining a method named

protected void Button1_Click(object sender, EventArgs e)

or you could just double click the button in the design view.

Here is a very quick sample of code to insert into a table in the button click event (codebehind)

protected void Button1_Click(object sender, EventArgs e)
{
   string name = TxtName.Text; // Scrub user data

   string connString = ConfigurationManager.ConnectionStrings["yourconnstringInWebConfig"].ConnectionString;
   SqlConnection conn = null;
   try
   {
          conn = new SqlConnection(connString);
          conn.Open();

          using(SqlCommand cmd = new SqlCommand())
          {
                 cmd.Conn = conn;
                 cmd.CommandType = CommandType.Text;
                 cmd.CommandText = "INSERT INTO dummyTable(name) Values (@var)";
                 cmd.Parameters.AddWithValue("@var", name);
                 int rowsAffected = cmd.ExecuteNonQuery();
                 if(rowsAffected ==1)
                 {
                        //Success notification
                 }
                 else
                 {
                        //Error notification
                 }
          }
   }
   catch(Exception ex)
   {
          //log error 
          //display friendly error to user
   }
   finally
   {
          if(conn!=null)
          {
                 //cleanup connection i.e close 
          }
   }
}

One option is Text::Trim:

use Text::Trim;
print trim("  example  ");

It looks like you've just finished step 3. Instead of running a function, you just print out a statement. A function is defined in the following way:

def addstudent():
    print("Student Added.")

then called by writing addstudent().

I would recommend using a while loop for your input. You can define the menu option outside the loop, put the print statement inside the loop, and do while(#valid option is not picked), then put the if statements after the while. Or you can do a while loop and continue the loop if a valid option is not selected.

Additionally, a dictionary is defined in the following way:

my_dict = {key:definition,...}

This should do the trick! :)

B1 =ROW(A5)

http://www.techonthenet.com/excel/formulas/row.php

In Java 8 with streams, it's pretty simple actually. EDIT: Can be efficient without streams, see lower.

List<String> listA = Arrays.asList("2009-05-18","2009-05-19","2009-05-21");
List<String> listB = Arrays.asList("2009-05-18","2009-05-18","2009-05-19","2009-05-19",
                                   "2009-05-20","2009-05-21","2009-05-21","2009-05-22");

List<String> result = listB.stream()
                           .filter(not(new HashSet<>(listA)::contains))
                           .collect(Collectors.toList());

Note that the hash set is only created once: The method reference is tied to its contains method. Doing the same with lambda would require having the set in a variable. Making a variable is not a bad idea, especially if you find it unsightly or harder to understand.

You can't easily negate the predicate without something like this utility method (or explicit cast), as you can't call the negate method reference directly (type inference is needed first).

private static <T> Predicate<T> not(Predicate<T> predicate) {
    return predicate.negate();
}

If streams had a filterOut method or something, it would look nicer.

Also, @Holger gave me an idea. ArrayList has its removeAll method optimized for multiple removals, it only rearranges its elements once. However, it uses the contains method provided by given collection, so we need to optimize that part if listA is anything but tiny.

With listA and listB declared previously, this solution doesn't need Java 8 and it's very efficient.

List<String> result = new ArrayList(listB);
result.removeAll(new HashSet<>(listA));

for anyone still looking for this , i just installed ohmyz https://ohmyz.sh/#install and the branches it's showing

According to Python3 documentation,python when divided by integer,will generate float despite expected to be integer.

For exclusively printing integer,use floor division method. Floor division is rounding off zero and removing decimal point. Represented by //

Hence,instead of 2/2 ,use 2//2

You can also import division from __future__ irrespective of using python2 or python3.

Hope it helps!

I like the challenge and wanted to give an answer, which solves the issue, I think.

1. Extract features (keypoints, descriptors such as SIFT, SURF) of the logo
2. Match the points with a model image of the logo (using Matcher such as Brute Force )
3. Estimate the coordinates of the rigid body (PnP problem - SolvePnP)
4. Estimate the cap position according to the rigid body
5. Do back-projection and calculate the image pixel position (ROI) of the cap of the bottle (I assume you have the intrinsic parameters of the camera)
6. Check with a method whether the cap is there or not. If there, then this is the bottle

Detection of the cap is another issue. It can be either complicated or simple. If I were you, I would simply check the color histogram in the ROI for a simple decision.

Please, give the feedback if I am wrong. Thanks.

DECLARE @v DATE= '3/15/2013'

SELECT CONVERT(VARCHAR(10), @v, 112)

you can convert any date format or date time format to YYYYMMDD with no delimiters

PHP native function exists for this. See http://php.net/manual/en/function.reset.php

Simply do this: mixed reset ( array &$array )

I would try any(byte[].class)

This way is comparatively more easy

SELECT doc_id,serial_number,status FROM date_time ORDER BY  date_time DESC LIMIT 0,1;
