I ran Visual Studio in Administrator mode and it worked for me :) Also, ensure that the app.config file which you are using for writing WCF configuration must be in the project where "ServiceHost" class is used, and not in actual WCF service project.

I think the best way to solve this is to follow the error advice, hence looking for server logs. To enable logs I added

 <system.diagnostics>
    <sources>
      <source name="System.ServiceModel" switchValue="Information, ActivityTracing" propagateActivity="true">
        <listeners>
          <add name="traceListener" type="System.Diagnostics.XmlWriterTraceListener" initializeData="c:\logs\TracesServ_ce.svclog" />
        </listeners>
      </source>
    </sources>
  </system.diagnostics>

Then you go to c:\logs\TracesServ_ce.svclog open it with microsoft service trace viewer. And see what the problem really is.

I've tried various solutions and none worked for me, after some more research I've found a solution that worked for me here

I posted it here, as this is the first google result for this problem so some others may find it useful.

Auto-incrementing the index in a loop:

myArr[(len(myArr)+1)]={"key":"val"}

The complement of a regular language is also a regular language, but to construct it you have to build the DFA for the regular language, and make any valid state change into an error. See this for an example. What the page doesn't say is that it converted /(ac|bd)/ into /(a[^c]?|b[^d]?|[^ab])/. The conversion from a DFA back to a regular expression is not trivial. It is easier if you can use the regular expression unchanged and change the semantics in code, like suggested before.

convert it into python datetime object if it isn't already. then add deltatime

one_years_later = Your_date + datetime.timedelta(days=(years*days_per_year)) 

for your case days=365.

you can have condition to check if the year is leap or no and adjust days accordingly

you can add as many years as you want

The fact that your method does not use the self argument (which is a reference to the instance that the method is attached to) doesn't mean you can leave it out. It always has to be there, because Python is always going to try to pass it in.

This is a sledgehammer approach to replacing raw UNICODE with HTML. I haven't seen any other place to put this solution, but I assume others have had this problem.

Apply this str_replace function to the RAW JSON, before doing anything else.

function unicode2html($str){
    $i=65535;
    while($i>0){
        $hex=dechex($i);
        $str=str_replace("\u$hex","&#$i;",$str);
        $i--;
     }
     return $str;
}

This won't take as long as you think, and this will replace ANY unicode with HTML.

Of course this can be reduced if you know the unicode types that are being returned in the JSON.

For example my code was getting lots of arrows and dingbat unicode. These are between 8448 an 11263. So my production code looks like:

$i=11263;
while($i>08448){
    ...etc...

You can look up the blocks of Unicode by type here: http://unicode-table.com/en/ If you know you're translating Arabic or Telegu or whatever, you can just replace those codes, not all 65,000.

You could apply this same sledgehammer to simple encoding:

 $str=str_replace("\u$hex",chr($i),$str);

Use ON DUPLICATE KEY UPDATE ...,
Negative : because the UPDATE uses resources for the second action.

Use INSERT IGNORE ...,
Negative : MySQL will not show any errors if something goes wrong, so you cannot handle the errors. Use it only if you don’t care about the query.

The problem is in the import line. You are importing a module, not a class. Assuming your file is named other_file.py (unlike java, again, there is no such rule as "one class, one file"):

from other_file import findTheRange

if your file is named findTheRange too, following java's convenions, then you should write

from findTheRange import findTheRange

you can also import it just like you did with random:

import findTheRange
operator = findTheRange.findTheRange()

Some other comments:

a) @Daniel Roseman is right. You do not need classes here at all. Python encourages procedural programming (when it fits, of course)

b) You can build the list directly:

  randomList = [random.randint(0, 100) for i in range(5)]

c) You can call methods in the same way you do in java:

largestInList = operator.findLargest(randomList)
smallestInList = operator.findSmallest(randomList)

d) You can use built in function, and the huge python library:

largestInList = max(randomList)
smallestInList = min(randomList)

e) If you still want to use a class, and you don't need self, you can use @staticmethod:

class findTheRange():
    @staticmethod
    def findLargest(_list):
        #stuff...

<?php
    
$string = "1,2,3";
$ids = explode(',', $string );

array_walk( $ids, function ( &$id )
{
    $id = (int) $id;
});
var_dump( $ids );

In Python 3, you can use * to create a new tuple of elements from the original tuple along with the new element.

>>> tuple1 = ("foo", "bar")
>>> tuple2 = (*tuple1, "baz")
>>> tuple2
('foo', 'bar', 'baz')

The byte code is almost the same as tuple1 + ("baz",)

              8 BUILD_TUPLE_UNPACK       2
             10 STORE_FAST               1 (tuple2)

             14 RETURN_VALUE

  2           0 LOAD_CONST               1 (('foo', 'bar'))
              2 STORE_FAST               0 (tuple1)

  3           4 LOAD_FAST                0 (tuple1)
              6 LOAD_CONST               2 (('baz',))
              8 BINARY_ADD
             10 STORE_FAST               1 (tuple2)

  4          12 LOAD_FAST                1 (tuple2)
             14 RETURN_VALUE

The only difference is BUILD_TUPLE_UNPACK vs BINARY_ADD. The exact performance depends on the Python interpreter implementation, but it's natural to implement BUILD_TUPLE_UNPACK faster than BINARY_ADD because BINARY_ADD is a polymorphic operator, requiring additional type calculation and implicit conversion.

default clean command did not work for me giving following error:

$ slack-cleaner --token=<TOKEN> --message --channel <CHANNEL>

Running slack-cleaner v0.2.4
Channel, direct message or private group not found

but following worked without any issue to clean the bot messages

slack-cleaner --token <TOKEN> --message --group <CHANNEL> --bot --perform --rate 1 

or

slack-cleaner --token <TOKEN> --message --group <CHANNEL> --user "*" --perform --rate 1 

to clean all the messages.

I use rate-limit of 1 second to avoid HTTP 429 Too Many Requests error because of slack api rate limit. In both cases, channel name was supplied without # sign

I found myself in a similar case, wanting to generate display groups of 3 columns each. However, although I was using bootstrap, I was trying to separate these groups into different parent divs. I also wanted to make something generically useful.

I approached it with 2 ng-repeat as below:

<div ng-repeat="items in quotes" ng-if="!($index % 3)">
  <div ng-repeat="quote in quotes" ng-if="$index <= $parent.$index + 2 && $index >= $parent.$index">
                ... some content ...
  </div>
</div>

This makes it very easy to change to a different number of columns, and separated out into several parent divs.

Check functions prettyNum, format

to have trialling zeros (123.1240 for example) use sprintf(x, fmt='%#.4g')

If you want see your buffer size in terminal, you can take a look at:

• /proc/sys/net/ipv4/tcp_rmem (for read)
• /proc/sys/net/ipv4/tcp_wmem (for write)

They contain three numbers, which are minimum, default and maximum memory size values (in byte), respectively.

Listview lv = (ListView) findViewById(R.id.previewlist);

    final BaseAdapter adapter = new PreviewAdapter(this, name, age);

            // TODO Auto-generated method stub


            View view = null;

            String value;
            for (int i = 0; i < adapter.getCount(); i++) {

                view = adapter.getView(i, view, lv);

                Textview et = (TextView) view.findViewById(R.id.passfare);


                value=et.getText().toString();

                 Toast.makeText(getApplicationContext(), value,
                 Toast.LENGTH_SHORT).show();
            }



        }
    });

Mates,

I stumbled upon this error today while testing a simple script. I am not using "class" function though so it take it with grain of salt. I was calling function before its definition & declaration ...something like this

      try{
             foo();
         }
       catch (exception $e)
           {
            echo "$e->getMessage()";
           }

       function foo(){
                       echo "blah blah blah";
                     }

so php was throwing me error "call to undefined function ".

This kinda seem classic programming error but may help someone in need of clue.

You can also use:

round(mod(rand.*max,max-1))+min

I'd start by the distinction that exists in Scala between def, val and var.

• def - defines an immutable label for the right side content which is lazily evaluated - evaluate by name.

• val - defines an immutable label for the right side content which is eagerly/immediately evaluated - evaluated by value.

• var - defines a mutable variable, initially set to the evaluated right side content.

Example, def

scala> def something = 2 + 3 * 4 
something: Int
scala> something  // now it's evaluated, lazily upon usage
res30: Int = 14

Example, val

scala> val somethingelse = 2 + 3 * 5 // it's evaluated, eagerly upon definition
somethingelse: Int = 17

Example, var

scala> var aVariable = 2 * 3
aVariable: Int = 6

scala> aVariable = 5
aVariable: Int = 5

According to above, labels from def and val cannot be reassigned, and in case of any attempt an error like the below one will be raised:

scala> something = 5 * 6
<console>:8: error: value something_= is not a member of object $iw
       something = 5 * 6
       ^

When the class is defined like:

scala> class Person(val name: String, var age: Int)
defined class Person

and then instantiated with:

scala> def personA = new Person("Tim", 25)
personA: Person

an immutable label is created for that specific instance of Person (i.e. 'personA'). Whenever the mutable field 'age' needs to be modified, such attempt fails:

scala> personA.age = 44
personA.age: Int = 25

as expected, 'age' is part of a non-mutable label. The correct way to work on this consists in using a mutable variable, like in the following example:

scala> var personB = new Person("Matt", 36)
personB: Person = Person@59cd11fe

scala> personB.age = 44
personB.age: Int = 44    // value re-assigned, as expected

as clear, from the mutable variable reference (i.e. 'personB') it is possible to modify the class mutable field 'age'.

I would still stress the fact that everything comes from the above stated difference, that has to be clear in mind of any Scala programmer.

Try this configuration. It worked for me:

<plugin>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <warSourceDirectory>mywebRoot</warSourceDirectory>

So, I know this is an old topic, but I'll first say it isn't possible. The closest thing currently is locking the mouse to a single position, and tracking change in its x and y. This concept has been adopted by - it looks like - Chrome and Firefox. It's managed by what's called Mouse Lock, and hitting escape will break it. From my brief read-up, I think the idea is that it locks the mouse to one location, and reports motion events similar to click-and-drag events.

Here's the release documentation:
FireFox: https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API
Chrome: http://www.chromium.org/developers/design-documents/mouse-lock

And here's a pretty neat demonstration: http://media.tojicode.com/q3bsp/

Many integrated products (especially by Apple) such as iPods, iPads are a good example of tight coupling: once the battery dies you might as well buy a new device because the battery is soldered fixed and won't come loose, thus making replacing very expensive. A loosely coupled player would allow effortlessly changing the battery.

The same goes for software development: it is generally (much) better to have loosely coupled code to facilitate extension and replacement (and to make individual parts easier to understand). But, very rarely, under special circumstances tight coupling can be advantageous because the tight integration of several modules allows for better optimisation.

I don't like adding new package into my project just to handle this simple task.

And also, I try my best to avoid RECURSIVE algorithm.... since, for most cases it is slower compared to non Recursive one.

So I made a function to get all the folder content (and its sub folder).... NON-Recursively

var getDirectoryContent = function(dirPath) {
    /* 
        get list of files and directories from given dirPath and all it's sub directories
        NON RECURSIVE ALGORITHM
        By. Dreamsavior
    */
    var RESULT = {'files':[], 'dirs':[]};

    var fs = fs||require('fs');
    if (Boolean(dirPath) == false) {
        return RESULT;
    }
    if (fs.existsSync(dirPath) == false) {
        console.warn("Path does not exist : ", dirPath);
        return RESULT;
    }

    var directoryList = []
    var DIRECTORY_SEPARATOR = "\\";
    if (dirPath[dirPath.length -1] !== DIRECTORY_SEPARATOR) dirPath = dirPath+DIRECTORY_SEPARATOR;

    directoryList.push(dirPath); // initial

    while (directoryList.length > 0) {
        var thisDir  = directoryList.shift(); 
        if (Boolean(fs.existsSync(thisDir) && fs.lstatSync(thisDir).isDirectory()) == false) continue;

        var thisDirContent = fs.readdirSync(thisDir);
        while (thisDirContent.length > 0) { 
            var thisFile  = thisDirContent.shift(); 
            var objPath = thisDir+thisFile

            if (fs.existsSync(objPath) == false) continue;
            if (fs.lstatSync(objPath).isDirectory()) { // is a directory
                let thisDirPath = objPath+DIRECTORY_SEPARATOR; 
                directoryList.push(thisDirPath);
                RESULT['dirs'].push(thisDirPath);

            } else  { // is a file
                RESULT['files'].push(objPath); 

            } 
        } 

    }
    return RESULT;
}

the only drawback of this function is that this is Synchronous function... You have been warned ;)

If you want a less verbose hack:

void deleteDirectory(String path) {
  Runtime.getRuntime().exec(String.format("rm -rf %s", path));
}

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

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

Another handy alternative is to use screen command to run the main program and direct the stderr and stdout to a file, then use tail -f to view the file as it is being written to.

You could also open another session if you don't want to use screen.

You can try this:

function search(data,search) {
    var obj = [], index=0;
    for(var i=0; i<data.length; i++) {
      for(key in data[i]){
         if(data[i][key].toString().toLowerCase().indexOf(search.toLowerCase())!=-1) {
                obj[index] = data[i];
                index++;
                break;
         }
     }
     return obj;
}
console.log(search(obj.list,'my Name'));

In my case above mentioned methods work fine with php but when i try to upload files with these methods in node.js then i have some problem. So instead of using $http({..,..,...}) use the normal jquery ajax.

For select file use this

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this)"/>

And in controller

$scope.uploadFile = function(element) {   
var data = new FormData();
data.append('file', $(element)[0].files[0]);
jQuery.ajax({
      url: 'brand/upload',
      type:'post',
      data: data,
      contentType: false,
      processData: false,
      success: function(response) {
      console.log(response);
      },
      error: function(jqXHR, textStatus, errorMessage) {
      alert('Error uploading: ' + errorMessage);
      }
 });   
};

Windows 7 x32 I found that no matter what I did, the driver being used dated back to 2006. It would not update, in fact Windows appears to be preferring the old driver to the new. I eventually found a way to sort it.

The Device Manager contains 'ghost' drivers that need to be deleted (if you have the same problem as I). To see them requires setting a variable in the registry, restarting and then deleting the likely redundant drivers.

Open the Device Manager from the command line use devmgmt.msc There are other ways, but this is easiest to describe. Currently it shows only 'current' drivers.

Open the System Properties box. Via Command line use sysdm.cpl

** Be aware that playing with area of your computer can break it. Back away if you are at all unsure of this. **

1. Open the Advanced tab, click Environmental Variables.
2. Under System Variables, click New.
3. Enter variable name devmgr_show_nonpresent_devices, under value enter 1.
4. Restart your computer.

Re-open the Device Manager, under view click Show Hidden Devices.

From here delete what you think are the problems then follow the advise you will have read elsewhere. On two seperate computers I have done this and found all I needed to do following this was download and install the standard google drivers as per user3079537's answer above. Good luck.

Luke's description of the function results in these scenarios seems to be right on. I only wish to understand the root cause and the PowerShell product team would do something about the behavior. It seems to be quite common and has cost me too much debugging time.

To get around this issue I've been using global variables rather than returning and using the value from the function call.

Here's another question on the use of global variables: Setting a global PowerShell variable from a function where the global variable name is a variable passed to the function

Instead of

Player[PlayerCount] thePlayers;

you want

Player[] thePlayers = new Player[PlayerCount];

and

for(int i = 0; i < PlayerCount ; i++)
{
    thePlayers[i] = new Player(i);
}
return thePlayers;

should return the array initialized with Player instances.

EDIT:

Do check out this table on wikipedia on naming conventions for java that is widely used.

Adding to what @KyleMit said, consider using:

• col-md-* classes for the larger outer columns
• col-xs-* classes for the smaller inner columns

This will be useful when you view the page on different screen sizes.

On a small screen, the wrapping of larger outer columns will then happen while maintaining the smaller inner columns, if possible

subprocess.call expects the same arguments as subprocess.Popen - that is a list of strings (the argv in C) rather than a single string.

It's quite possible that your child process attempted to run "s" with the parameters "o", "m", "e", ...

There's no such thing as a global variable in C#. Period.

You can have static members if you want:

public static class MyStaticValues
{
   public static bool MyStaticBool {get;set;}
}

I like the solution posted by user1786647, and I've updated it a little to change the timezone to a function argument and add optional support for passing either a Unix time or datetime string to use for the returned datestamp.

It also includes a fallback for "setTimestamp" for users running version lower than PHP 5.3:

function DateStamp($strDateTime = null, $strTimeZone = "Europe/London") {
    $objTimeZone = new DateTimeZone($strTimeZone);

    $objDateTime = new DateTime();
    $objDateTime->setTimezone($objTimeZone);

    if (!empty($strDateTime)) {
        $fltUnixTime = (is_string($strDateTime)) ? strtotime($strDateTime) : $strDateTime;

        if (method_exists($objDateTime, "setTimestamp")) {
            $objDateTime->setTimestamp($fltUnixTime);
        }
        else {
            $arrDate = getdate($fltUnixTime);

        }
    }
    return $objDateTime->format("Y-m-d H:i:s");
}

For those looking for an SCSS mixin instead, including woff2:

@mixin fface($path, $family, $type: '', $weight: 400, $svg: '', $style: normal) {
  @font-face {
    font-family: $family;
    @if $svg == '' {
      // with OTF without SVG and EOT
      src: url('#{$path}#{$type}.otf') format('opentype'), url('#{$path}#{$type}.woff2') format('woff2'), url('#{$path}#{$type}.woff') format('woff'), url('#{$path}#{$type}.ttf') format('truetype');
    } @else {
      // traditional src inclusions
      src: url('#{$path}#{$type}.eot');
      src: url('#{$path}#{$type}.eot?#iefix') format('embedded-opentype'), url('#{$path}#{$type}.woff2') format('woff2'), url('#{$path}#{$type}.woff') format('woff'), url('#{$path}#{$type}.ttf') format('truetype'), url('#{$path}#{$type}.svg##{$svg}') format('svg');
    }
    font-weight: $weight;
    font-style: $style;
  }
}
// ========================================================importing
$dir: '/assets/fonts/';
$famatic: 'AmaticSC';
@include fface('#{$dir}amatic-sc-v11-latin-regular', $famatic, '', 400, $famatic);

$finter: 'Inter';
// adding specific types of font-weights
@include fface('#{$dir}#{$finter}', $finter, '-Thin-BETA', 100);
@include fface('#{$dir}#{$finter}', $finter, '-Regular', 400);
@include fface('#{$dir}#{$finter}', $finter, '-Medium', 500);
@include fface('#{$dir}#{$finter}', $finter, '-Bold', 700);
// ========================================================usage
.title {
  font-family: Inter;
  font-weight: 700; // Inter-Bold font is loaded
}
.special-title {
  font-family: AmaticSC;
  font-weight: 700; // default font is loaded
}

The $type parameter is useful for stacking related families with different weights.

The @if is due to the need of supporting the Inter font (similar to Roboto), which has OTF but doesn't have SVG and EOT types at this time.

If you get a can't resolve error, remember to double check your fonts directory ($dir).

The cause of the error is the use of the internal PHP programming data structures function, array_shift() [php.net/end].

The function takes an array as a parameter. Although an ampersand is indicated in the prototype of array_shift() in the manual", there isn't any cautionary documentation following in the extended definition of that function, nor is there any apparent explanation that the parameter is in fact passed by reference.

Perhaps this is /understood/. I did not understand, however, so it was difficult for me to detect the cause of the error.

Reproduce code:

function get_arr()
{
    return array(1, 2);
}
$array = get_arr();
$el = array_shift($array);

It's the other way round:

Vehicle[] car = new Vehicle[N];

This makes more sense, as the number of elements in the array isn't part of the type of car, but it is part of the initialization of the array whose reference you're initially assigning to car. You can then reassign it in another statement:

car = new Vehicle[10]; // Creates a new array

(Note that I've changed the type name to match Java naming conventions.)

For further information about arrays, see section 10 of the Java Language Specification.

Our team had the same need with a remote SSH-executed script which was timing out after 25 minutes of inactivity. Here is a solution with the monitoring loop checking the background process every second, but printing only every 10 minutes to suppress an inactivity timeout.

long_running.sh & 
pid=$!

# Wait on a background job completion. Query status every 10 minutes.
declare -i elapsed=0
# `ps -p ${pid}` works on macOS and CentOS. On both OSes `ps ${pid}` works as well.
while ps -p ${pid} >/dev/null; do
  sleep 1
  if ((++elapsed % 600 == 0)); then
    echo "Waiting for the completion of the main script. $((elapsed / 60))m and counting ..."
  fi
done

# Return the exit code of the terminated background process. This works in Bash 4.4 despite what Bash docs say:
# "If neither jobspec nor pid specifies an active child process of the shell, the return status is 127."
wait ${pid}

You can make the id the primary key, and set member_id to NOT NULL UNIQUE. (Which you've done.) Columns that are NOT NULL UNIQUE can be the target of foreign key references, just like a primary key can. (I'm pretty sure that's true of all SQL platforms.)

At the conceptual level, there's no difference between PRIMARY KEY and NOT NULL UNIQUE. At the physical level, this is a MySQL issue; other SQL platforms will let you use a sequence without making it the primary key.

But if performance is really important, you should think twice about widening your table by four bytes per row for that tiny visual convenience. In addition, if you switch to INNODB in order to enforce foreign key constraints, MySQL will use your primary key in a clustered index. Since you're not using your primary key, I imagine that could hurt performance.

Option 1- From Studio

In Android Studio, go to File > Project Structure. Then select the "project" tab on the left.

Your Gradle version will be displayed here.

Option 2- gradle-wrapper.properties

If you are using the Gradle wrapper, then your project will have a gradle/wrapper/gradle-wrapper.properties folder.

This file should contain a line like this:

distributionUrl=https\://services.gradle.org/distributions/gradle-2.2.1-all.zip

This determines which version of Gradle you are using. In this case, gradle-2.2.1-all.zip means I am using Gradle 2.2.1.

Option 3- Local Gradle distribution

If you are using a version of Gradle installed on your system instead of the wrapper, you can run gradle --version to check.

Lots of people have suggested POSIX sleep, Windows Sleep, Windows system("pause"), C++ cin.get()… there's even a DOS getch() in there, from roughly the late 1920s.

Please don't do any of these.

None of these solutions would pass code review in my team. That means, if you submitted this code for inclusion in our products, your commit would be blocked and you would be told to go and find another solution. (One might argue that things aren't so serious when you're just a hobbyist playing around, but I propose that developing good habits in your pet projects is what will make you a valued professional in a business organisation, and keep you hired.)

Keeping the console window open so you can read the output of your program is not the responsibility of your program! When you add a wait/sleep/block to the end of your program, you are violating the single responsibility principle, creating a massive abstraction leak, and obliterating the re-usability/chainability of your program. It no longer takes input and gives output — it blocks for transient usage reasons. This is very non-good.

Instead, you should configure your environment to keep the prompt open after your program has finished its work. Your Batch script wrapper is a good approach! I can see how it would be annoying to have to keep manually updating, and you can't invoke it from your IDE. You could make the script take the path to the program to execute as a parameter, and configure your IDE to invoke it instead of your program directly.

An interim, quick-start approach would be to change your IDE's run command from cmd.exe <myprogram> or <myprogram>, to cmd.exe /K <myprogram>. The /K switch to cmd.exe makes the prompt stay open after the program at the given path has terminated. This is going to be slightly more annoying than your Batch script solution, because now you have to type exit or click on the red 'X' when you're done reading your program's output, rather than just smacking the space bar.

^{I assume usage of an IDE, because otherwise you're already invoking from a command prompt, and this would not be a problem in the first place. Furthermore, I assume the use of Windows (based on detail given in the question), but this answer applies to any platform… which is, incidentally, half the point.}

I've just had this happen to me - and (while it was not instantly obvious) it was due to Resharper (R#) being disabled during a licensing issue.

Enabling Resharper fixed this for me!

I just did 'svn revert /blabla' and it worked, the folder is back and I can svn delete it

I solved this problem using an Attached Behavior rather than an Expression Behavior as in Sergey's answer. This means I don't need a dependency on System.Windows.Interactivity in the Blend SDK:

public class TextBoxBehavior
{
    public static bool GetSelectAllTextOnFocus(TextBox textBox)
    {
        return (bool)textBox.GetValue(SelectAllTextOnFocusProperty);
    }

    public static void SetSelectAllTextOnFocus(TextBox textBox, bool value)
    {
        textBox.SetValue(SelectAllTextOnFocusProperty, value);
    }

    public static readonly DependencyProperty SelectAllTextOnFocusProperty =
        DependencyProperty.RegisterAttached(
            "SelectAllTextOnFocus",
            typeof (bool),
            typeof (TextBoxBehavior),
            new UIPropertyMetadata(false, OnSelectAllTextOnFocusChanged));

    private static void OnSelectAllTextOnFocusChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var textBox = d as TextBox;
        if (textBox == null) return;

        if (e.NewValue is bool == false) return;

        if ((bool) e.NewValue)
        {
            textBox.GotFocus += SelectAll;
            textBox.PreviewMouseDown += IgnoreMouseButton;
        }
        else
        {
            textBox.GotFocus -= SelectAll;
            textBox.PreviewMouseDown -= IgnoreMouseButton;
        }
    }

    private static void SelectAll(object sender, RoutedEventArgs e)
    {
        var textBox = e.OriginalSource as TextBox;
        if (textBox == null) return;
        textBox.SelectAll();
    }

    private static void IgnoreMouseButton(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {
        var textBox = sender as TextBox;
        if (textBox == null || (!textBox.IsReadOnly && textBox.IsKeyboardFocusWithin)) return;

        e.Handled = true;
        textBox.Focus();
    }
}

You can then use it in your XAML like this:

<TextBox Text="Some Text" behaviors:TextBoxBehavior.SelectAllTextOnFocus="True"/>

I blogged about it here.

C# supports some inherited covariance for event delegates, so a method like this:

void LowestCommonHander( object sender, EventArgs e ) { ... } 

Can be used to subscribe to your event, no explicit cast required

gcInt.MyEvent += LowestCommonHander;

You can even use lambda syntax and the intellisense will all be done for you:

gcInt.MyEvent += (sender, e) =>
{
    e. //you'll get correct intellisense here
};

Syntax of JSON

object = {} | { members }

• members = pair | pair, members
• pair = string : value

array = [] | [ elements ]

• elements = value | value elements

value = string|number|object|array|true|false|null

What you want can be achieved by modifying the hosts file through Fiddler 2 application.

Follow these steps:

1. Install Fiddler2

2. Navigate to Fiddler2 menu:- Tools > HOSTS.. (Click to select)

3. Add a line like this:-

   localhost:8080 www.mydomainname.com

4. Save the file & then checkout www.mydomainname.com in browser.

When you use QDir.mkpath() it returns true if the path already exists, in the other hand QDir.mkdir() returns false if the path already exists. So depending on your program you have to choose which fits better.

You can see more on Qt Documentation

I managed to use soap,wsdl and Node.js You need to install soap with npm install soap

Create a node server called server.js that will define soap service to be consumed by a remote client. This soap service computes Body Mass Index based on weight(kg) and height(m).

const soap = require('soap');
const express = require('express');
const app = express();
/**
 * this is remote service defined in this file, that can be accessed by clients, who will supply args
 * response is returned to the calling client
 * our service calculates bmi by dividing weight in kilograms by square of height in metres
 */
const service = {
  BMI_Service: {
    BMI_Port: {
      calculateBMI(args) {
        //console.log(Date().getFullYear())
        const year = new Date().getFullYear();
        const n = args.weight / (args.height * args.height);
        console.log(n);
        return { bmi: n };
      }
    }
  }
};
// xml data is extracted from wsdl file created
const xml = require('fs').readFileSync('./bmicalculator.wsdl', 'utf8');
//create an express server and pass it to a soap server
const server = app.listen(3030, function() {
  const host = '127.0.0.1';
  const port = server.address().port;
});
soap.listen(server, '/bmicalculator', service, xml);

Next, create a client.js file that will consume soap service defined by server.js. This file will provide arguments for the soap service and call the url with SOAP's service ports and endpoints.

const express = require('express');
const soap = require('soap');
const url = 'http://localhost:3030/bmicalculator?wsdl';
const args = { weight: 65.7, height: 1.63 };
soap.createClient(url, function(err, client) {
  if (err) console.error(err);
  else {
    client.calculateBMI(args, function(err, response) {
      if (err) console.error(err);
      else {
        console.log(response);
        res.send(response);
      }
    });
  }
});

Your wsdl file is an xml based protocol for data exchange that defines how to access a remote web service. Call your wsdl file bmicalculator.wsdl

To get the index values as a list/list of tuples for Index/MultiIndex do:

df.index.values.tolist()  # an ndarray method, you probably shouldn't depend on this

or

list(df.index.values)  # this will always work in pandas

I don't have enough reputation points to comment on @greg's answer above, so will add my observations here. I have a Swift project for both iPad and iPhone. I have a method inside my main view controller (relevant bit below). When I test this on a phone, everything works properly and no warnings are generated. When I run it on an iPad, everything works properly but I see the warning about snapshotting the view. The interesting bit, however, is that when I run on an iPad without using the popover controller, everything works properly with no warning. Unfortunately, Apple mandates that the image picker must be used within a popover on iPad, if the camera is not being used.

    dispatch_async(dispatch_get_main_queue(), {
        let imagePicker: UIImagePickerController = UIImagePickerController();
        imagePicker.sourceType = UIImagePickerControllerSourceType.SavedPhotosAlbum;
        imagePicker.mediaTypes = [kUTTypeImage];
        imagePicker.allowsEditing = false;
        imagePicker.delegate = self;

        if(UIDevice.currentDevice().userInterfaceIdiom == .Pad){ // on a tablet, the image picker is supposed to be in a popover
            let popRect: CGRect = buttonRect;
            let popover: UIPopoverController = UIPopoverController(contentViewController: imagePicker);
            popover.presentPopoverFromRect(popRect, inView: self.view, permittedArrowDirections: UIPopoverArrowDirection.Up, animated: true);
        }else{
            self.presentViewController(imagePicker, animated: true, completion: nil);
        }
    });

        }

                using (DbConnection conn = _context.Database.GetDbConnection())
                {
                    if (conn.State != System.Data.ConnectionState.Open)
                        conn.Open();
                    var cmd = conn.CreateCommand();
                    cmd.CommandText = "Reset_Data";
                    await cmd.ExecuteNonQueryAsync();
                }
                return new OkObjectResult(1);
            }
            catch (Exception ex)
            {
                return new BadRequestObjectResult(ex.Message);
            }
        }
    }
}

You use the Python 2 docs but write your program in Python 3.

For 2 use cases:

1. I only want n overall results, not n results per file, the grep -m 2 is per file max occurrence.
2. I often use git grep which doesn't take -m

A good alternative in these scenarios is grep | sed 2q to grep first 2 occurrences across all files. sed documentation: https://www.gnu.org/software/sed/manual/sed.html

You missed putting single quotes around your array keys:

$_POST[email]

should be:

$_POST['email']

            //For me it's the best way to look for the value of a spezific column
            int seekValue = 5;
            foreach (DataGridViewRow row in dataGridView1.Rows)
            {
                var columnValue = Convert.ToInt32(row.Cells["ColumnName"].Value);
                if (columnValue == seekValue)
                {
                    dataGridView1.CurrentCell = row.Cells[0];
                }
            }

The simple and official way would be this:

  rails g migration drop_tablename

Now go to your db/migrate and look for your file which contains the drop_tablename as the filename and edit it to this.

    def change
      drop_table :table_name
    end

Then you need to run

    rake db:migrate 

on your console.

Below command will work in command prompt:

copy c:\folder\file.ext \\dest-machine\destfolder /Z /Y

To Copy all files:

copy c:\folder\*.* \\dest-machine\destfolder /Z /Y

The above post & answers are rapidly becoming dated as the development of LXD continues to enhance LXC. Yes, I know Docker hasn't stood still either.

LXD now implements a repository for LXC container images which a user can push/pull from to contribute to or reuse.

LXD's REST api to LXC now enables both local & remote creation/deployment/management of LXC containers using a very simple command syntax.

Key features of LXD are:

• Secure by design (unprivileged containers, resource restrictions and much more)
• Scalable (from containers on your laptop to thousand of compute nodes)
• Intuitive (simple, clear API and crisp command line experience)
• Image based (no more distribution templates, only good, trusted images) Live migration

There is NCLXD plugin now for OpenStack allowing OpenStack to utilize LXD to deploy/manage LXC containers as VMs in OpenStack instead of using KVM, vmware etc.

However, NCLXD also enables a hybrid cloud of a mix of traditional HW VMs and LXC VMs.

The OpenStack nclxd plugin a list of features supported include:

stop/start/reboot/terminate container
Attach/detach network interface
Create container snapshot
Rescue/unrescue instance container
Pause/unpause/suspend/resume container
OVS/bridge networking
instance migration
firewall support

By the time Ubuntu 16.04 is released in Apr 2016 there will have been additional cool features such as block device support, live-migration support.

Take the case of two tables, Books and Orders. In case, we increase the number of books in a particular order with Order.ID = 1002 in Orders table then we also need to reduce that the total number of books available in our stock by the same number in Books table.

UPDATE Books, Orders
SET Orders.Quantity = Orders.Quantity + 2,
    Books.InStock = Books.InStock - 2
WHERE
    Books.BookID = Orders.BookID

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

I know this is late, but for future reference, put the date format into a recognised format by using str_replace then your function will work. (replace the underscore with a dash)

//change the format to dashes instead of underscores, then get the timestamp

$date2 = strtotime(str_replace("_", "-",$date2));

//compare the dates
if($date1 < $date2){
   //convert the date back to underscore format if needed when printing it out.

I think the most easily understandable way is to first calculate the distance between the circle's center and the point. I would use this formula:

d = sqrt((circle_x - x)^2 + (circle_y - y)^2)

Then, simply compare the result of that formula, the distance (d), with the radius. If the distance (d) is less than or equal to the radius (r), the point is inside the circle (on the edge of the circle if d and r are equal).

Here is a pseudo-code example which can easily be converted to any programming language:

function is_in_circle(circle_x, circle_y, r, x, y)
{
    d = sqrt((circle_x - x)^2 + (circle_y - y)^2);
    return d <= r;
}

Where circle_x and circle_y is the center coordinates of the circle, r is the radius of the circle, and x and y is the coordinates of the point.

If you have bash (e.g. git bash), you can use the following script to convert from unix2dos:

ex filename.ext <<EOF
:set fileformat=dos
:wq
EOF

similarly, to convert from dos2unix:

ex filename.ext <<EOF
:set fileformat=unix
:wq
EOF

I believe that using "cbind" is the simplest way to add a column to a data frame in R. Below an example:

    myDf = data.frame(index=seq(1,10,1), Val=seq(1,10,1))
    newCol= seq(2,20,2)
    myDf = cbind(myDf,newCol)

:%s/\(^\s*\)\@<=    /\t/g

Translation: Search for every instance of 4 consecutive spaces (after the = character), but only if the entire line up to that point is whitespace (this uses the zero-width look-behind assertion, \@<=). Replace each found instance with a tab character.

> sudo nano /etc/mysql/my.cnf

Enter below

[mysqld]
sql_mode = ""

Ctrl + O => Y = Ctrl + X

> sudo service mysql restart

Short version:

$ svn st
!  +  C foo
      >   local edit, incoming delete upon update
!  +  C bar
      >   local edit, incoming delete upon update
$ touch foo bar
$ svn revert foo bar
$ rm foo bar

If the conflict is about directories instead of files then replace touch with mkdir and rm with rm -r.

Note: the same procedure also work for the following situation:

$ svn st
!     C foo
      >   local delete, incoming delete upon update
!     C bar
      >   local delete, incoming delete upon update

Long version:

This happens when you edit a file while someone else deleted the file and commited first. As a good svn citizen you do an update before a commit. Now you have a conflict. Realising that deleting the file is the right thing to do you delete the file from your working copy. Instead of being content svn now complains that the local files are missing and that there is a conflicting update which ultimately wants to see the files deleted. Good job svn.

Should svn resolve not work, for whatever reason, you can do the following:

Initial situation: Local files are missing, update is conflicting.

$ svn st
!  +  C foo
      >   local edit, incoming delete upon update
!  +  C bar
      >   local edit, incoming delete upon update

Recreate the conflicting files:

$ touch foo bar

If the conflict is about directories then replace touch with mkdir.

New situation: Local files to be added to the repository (yeah right, svn, whatever you say), update still conflicting.

$ svn st
A  +  C foo
      >   local edit, incoming delete upon update
A  +  C bar
      >   local edit, incoming delete upon update

Revert the files to the state svn likes them (that means deleted):

$ svn revert foo bar

New situation: Local files not known to svn, update no longer conflicting.

$ svn st
?       foo
?       bar

Now we can delete the files:

$ rm foo bar

If the conflict is about directories then replace rm with rm -r.

svn no longer complains:

$ svn st

Done.

SET UP THE REPOSITORY

For Ubuntu 14.04/16.04/16.10/17.04:

sudo add-apt-repository "deb [arch=amd64] \
     https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

For Ubuntu 17.10:

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu zesty stable"

Add Docker’s official GPG key:

$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

Then install

$ sudo apt-get update && sudo apt-get -y install docker-ce

Actually, We found a way to do this:

DECLARE @username varchar(50)
SET @username = 'username'
DECLARE @Output as numeric(18,4)
DECLARE @OpenSelect As nvarchar(500)
SET @OpenSelect = '(SELECT @Output = CAST((CAST(pwdLastSet As bigint) / 864000000000) As numeric(18,4)) FROM OpenQuery (ADSI,''SELECT pwdLastSet
                                FROM  ''''LDAP://domain.net.intra/DC=domain,DC=net,DC=intra''''
                                WHERE objectClass =  ''''User'''' AND sAMAccountName = ''''' + @username + '''''
                          '') AS tblADSI)'
EXEC sp_executesql @OpenSelect, N'@Output numeric(18,4) out', @Output out
SELECT @Output As Outputs

This will assign the result of the OpenQuery execution, in the variable @Output.

We tested for Store procedure in MSSQL 2012, but should work with MSSQL 2008+.

Microsoft Says that sp_executesql(Transact-SQL): Applies to: SQL Server (SQL Server 2008 through current version), Windows Azure SQL Database (Initial release through current release). (http://msdn.microsoft.com/en-us/library/ms188001.aspx)

Alternative simpler solution is to use rsync utility:

sudo rsync -vuar --delete-after --dry-run path/subfolder/ path/

^{Note: Above command will show what is going to be changed. To execute the actual changes, remove --dry-run.}

The advantage is that the original folder (subfolder) would be removed as well as part of the command, and when using mv examples here you still need to clean up your folders, not to mention additional headache to cover hidden and non-hidden files in one single pattern.

In addition rsync provides support of copying/moving files between remotes and it would make sure that files are copied exactly as they originally were (-a).

The used -u parameter would skip existing newer files, -r recurse into directories and -v would increase verbosity.

A connection socket (fd) is presented for local address + local port + peer address + peer port. Process recv/send data via socket abstract. A listening socket (fd) is presented for local address + local listening port. Process can accept new connection via socket.

A dict is a hash table, so it is really fast to find the keys. So between dict and list, dict would be faster. But if you don't have a value to associate, it is even better to use a set. It is a hash table, without the "table" part.

EDIT: for your new question, YES, a set would be better. Just create 2 sets, one for sequences ended in 1 and other for the sequences ended in 89. I have sucessfully solved this problem using sets.

With that code you can simply;

document.write(dayNames[now.getDay()] + " (" + now.getWeek() + ").");

(You will need to paste the getWeek function above your current script)

Here's how I do it: I put m2e's lifecycle-mapping plugin in a separate profile instead of the default <build> section. the profile is auto-activated during eclipse builds by presence of a m2e property (instead of manual activation in settings.xml or otherwise). this will handle the m2e cases, while command-line maven will simply skip the profile and the m2e lifecycle-mapping plugin without any warnings, and everybody is happy.

Even, I have faced the same issue.

I have fixed the issue by referring the above Solution 2 with the new g??radle-4.1 :

I have done the following gradle changes. It seems downloading resources through maven Amazon helped me to fix the issue, there are issues with appcompat library. Check and ensure that appcompat compatible support libraries downloaded in your system. What I feel, it just simply the resources not downloaded through maven, causing the compile error issue. Ensure the resources are found in your local drive to fix the issue.

Just Played around with

1. Maven Amazon url

repositories {
    maven {
        url "https://s3.amazonaws.com/repo.commonsware.com"
    }
    jcenter()
}

2. Compatible support libraries downloaded in the drive and referring compatible libraries in gradle.

You can copy the HTML code to the clipboard and paste special it back as Unicode text. Excel will render the HTML in the cell. Check out this post http://www.dailydoseofexcel.com/archives/2005/02/23/html-in-cells-ii/

The relevant macro code from the post:

Private Sub Worksheet_Change(ByVal Target As Range)

   Dim objData As DataObject
   Dim sHTML As String
   Dim sSelAdd As String

   Application.EnableEvents = False

   If Target.Cells.Count = 1 Then
      If LCase(Left(Target.Text, 6)) = "<html>" Then
         Set objData = New DataObject

         sHTML = Target.Text

         objData.SetText sHTML
         objData.PutInClipboard

         sSelAdd = Selection.Address
         Target.Select

After validation and before INSERT check if username already exists, using mysqli(procedural). This works:

SQL 2003 standard defines the format as follows:

<date value> ::= <years value> <minus sign> <months value> <minus sign> <days value>
<time value> ::= <hours value> <colon> <minutes value> <colon> <seconds value>

There are some definitions in between that just link back to these, but in short YYYY-MM-DD HH:MM:SS with optional .mmm milliseconds is required to work on all SQL databases.

Oracle SQL:

There is the "IN" Operator in Oracle SQL which can be used for that:

1. Go to File >> Settings >> Plugins and install the plugin PyCharm cell mode
2. Go to File >> Settings >> Appearance & Behavior >> Keymap and assign your keyboard shortcuts for Run Cell and Run Cell and go to next

A cell is delimited by ##

Ref https://plugins.jetbrains.com/plugin/7858-pycharm-cell-mode

innerHTML sets the text (including html elements) inside an element. Normally we use it for elements like div, span etc to insert other html elements inside it.

For your case you want to set the value of an input element. So you should use the value attribute.

Change innerHTML to value

document.getElementById('add').value = sum;

For me, this was the easiest solution: I added the font-size:62.5%; to the first .ui-datepicker tag in the jquery custom css file:

before:

.ui-datepicker { width: 17em; padding: .2em .2em 0; display: none;} 

after:

.ui-datepicker { width: 17em; padding: .2em .2em 0; display: none; font-size:62.5%; }

The way you use the csv module changed in Python 3 in several respects (docs), at least with respect to how you need to open the file. Anyway, something like

import csv
with open('test.csv', 'w', newline='') as fp:
    a = csv.writer(fp, delimiter=',')
    data = [['Me', 'You'],
            ['293', '219'],
            ['54', '13']]
    a.writerows(data)

should work.

You can use IPython.display.clear_output to clear the output of a cell.

from IPython.display import clear_output

for i in range(10):
    clear_output(wait=True)
    print("Hello World!")

At the end of this loop you will only see one Hello World!.

Without a code example it's not easy to give you working code. Probably buffering the latest n events is a good strategy. Whenever the buffer changes you can clear the cell's output and print the buffer again.

use labelpad parameter:

pl.xlabel("...", labelpad=20)

or set it after:

ax.xaxis.labelpad = 20

You can use global like so:

global._ = require('underscore')

Update: Chrome 58+ hid these and other debug messages by default. To display them click the arrow next to 'Info' and select 'Verbose'.

Chrome 57 turned on 'hide violations' by default. To turn them back on you need to enable filters and uncheck the 'hide violations' box.

suddenly it appears when someone else involved in the project

I think it's more likely you updated to Chrome 56. This warning is a wonderful new feature, in my opinion, please only turn it off if you're desperate and your assessor will take marks away from you. The underlying problems are there in the other browsers but the browsers just aren't telling you there's a problem. The Chromium ticket is here but there isn't really any interesting discussion on it.

These messages are warnings instead of errors because it's not really going to cause major problems. It may cause frames to get dropped or otherwise cause a less smooth experience.

They're worth investigating and fixing to improve the quality of your application however. The way to do this is by paying attention to what circumstances the messages appear, and doing performance testing to narrow down where the issue is occurring. The simplest way to start performance testing is to insert some code like this:

function someMethodIThinkMightBeSlow() {
    const startTime = performance.now();

    // Do the normal stuff for this function

    const duration = performance.now() - startTime;
    console.log(`someMethodIThinkMightBeSlow took ${duration}ms`);
}

If you want to get more advanced, you could also use Chrome's profiler, or make use of a benchmarking library like this one.

Once you've found some code that's taking a long time (50ms is Chrome's threshold), you have a couple of options:

1. Cut out some/all of that task that may be unnecessary
2. Figure out how to do the same task faster
3. Divide the code into multiple asynchronous steps

(1) and (2) may be difficult or impossible, but it's sometimes really easy and should be your first attempts. If needed, it should always be possible to do (3). To do this you will use something like:

setTimeout(functionToRunVerySoonButNotNow);

or

// This one is not available natively in IE, but there are polyfills available.
Promise.resolve().then(functionToRunVerySoonButNotNow);

You can read more about the asynchronous nature of JavaScript here.

Short answer is no.

XAMPP is normally built around a specific PHP version to ensure plugins and modules are all compatible and working correctly.

If your project specifically needs PHP 5.3 - the cleanest method is simply reinstalling an older version of XAMPP with PHP 5.3 packaged into it.

XAMPP 1.7.7 was their last update before moving off PHP 5.3.

Here is another example using the lapply and table functions in base R.

freqList = lapply(select_if(tips, is.factor), 
              function(x) {
                  df = data.frame(table(x))

                  df = data.frame(fct = df[, 1], 
                                  n = sapply(df[, 2], function(y) {
                                      round(y / nrow(dat), 2)
                                    }
                                )
                            )
                  return(df) 
                    }
                )

Use print(freqList) to see the proportion tables (percent of frequencies) for each column/feature/variable (depending on your tradecraft) that is labeled as a factor.

Suppose you have the following code:

import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class Test {
    public static void main(String[] s) {
        Map<String, Boolean> whoLetDogsOut = new ConcurrentHashMap<>();
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
        whoLetDogsOut.computeIfAbsent("snoop", k -> f(k));
    }
    static boolean f(String s) {
        System.out.println("creating a value for \""+s+'"');
        return s.isEmpty();
    }
}

Then you will see the message creating a value for "snoop" exactly once as on the second invocation of computeIfAbsent there is already a value for that key. The k in the lambda expression k -> f(k) is just a placeolder (parameter) for the key which the map will pass to your lambda for computing the value. So in the example the key is passed to the function invocation.

Alternatively you could write: whoLetDogsOut.computeIfAbsent("snoop", k -> k.isEmpty()); to achieve the same result without a helper method (but you won’t see the debugging output then). And even simpler, as it is a simple delegation to an existing method you could write: whoLetDogsOut.computeIfAbsent("snoop", String::isEmpty); This delegation does not need any parameters to be written.

To be closer to the example in your question, you could write it as whoLetDogsOut.computeIfAbsent("snoop", key -> tryToLetOut(key)); (it doesn’t matter whether you name the parameter k or key). Or write it as whoLetDogsOut.computeIfAbsent("snoop", MyClass::tryToLetOut); if tryToLetOut is static or whoLetDogsOut.computeIfAbsent("snoop", this::tryToLetOut); if tryToLetOut is an instance method.

You can also use,

output <- as.matrix(as.data.frame(z))

The memory usage is very similar to

output <- matrix(unlist(z), ncol = 10, byrow = TRUE)

Which can be verified, with mem_changed() from library(pryr).

Are you using Windows Forms? If you've added the image using the Properties/Resources UI, you get access to the image from generated code, so you can simply do this:

var bmp = new Bitmap(WindowsFormsApplication1.Properties.Resources.myimage);

try this: (you missed the single quotes)

var floorplanSettings = '@Html.Raw(Json.Encode(Model.FloorPlanSettings))';

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)
                .OrderBy(w => w.Frequency);

For the distributed portion, you could check out DryadLINQ: http://research.microsoft.com/en-us/projects/dryadlinq/default.aspx

for horizontal lines you can use hr tag:

hr { width: 90%; }

but its not possible to limit border height. only element height.

5 Jan 2021: link update thanks to @Sadap's comment.

Kind of a corollary answer: the people on this site have taken the time to make tables of macros defined for every OS/compiler pair.

For example, you can see that _WIN32 is NOT defined on Windows with Cygwin (POSIX), while it IS defined for compilation on Windows, Cygwin (non-POSIX), and MinGW with every available compiler (Clang, GNU, Intel, etc.).

Anyway, I found the tables quite informative and thought I'd share here.

This examples shows how to realize the confirmed window close operation.

The window has a Window adapter which switches the default close operation to EXIT_ON_CLOSEor DO_NOTHING_ON_CLOSE dependent on your answer in the OptionDialog.

The method closeWindow of the ConfirmedCloseWindow fires a close window event and can be used anywhere i.e. as an action of an menu item

public class WindowConfirmedCloseAdapter extends WindowAdapter {

    public void windowClosing(WindowEvent e) {

        Object options[] = {"Yes", "No"};

        int close = JOptionPane.showOptionDialog(e.getComponent(),
                "Really want to close this application?\n", "Attention",
                JOptionPane.YES_NO_OPTION,
                JOptionPane.INFORMATION_MESSAGE,
                null,
                options,
                null);

        if(close == JOptionPane.YES_OPTION) {
           ((JFrame)e.getSource()).setDefaultCloseOperation(
                   JFrame.EXIT_ON_CLOSE);
        } else {
           ((JFrame)e.getSource()).setDefaultCloseOperation(
                   JFrame.DO_NOTHING_ON_CLOSE);
        }
    }
}

public class ConfirmedCloseWindow extends JFrame {

    public ConfirmedCloseWindow() {

        addWindowListener(new WindowConfirmedCloseAdapter());
    }

    private void closeWindow() {
        processWindowEvent(new WindowEvent(this, WindowEvent.WINDOW_CLOSING));
    }
}

You need to change from queue import Queue to from multiprocessing import Queue.

The root reason is the former Queue is designed for threading module Queue while the latter is for multiprocessing.Process module.

For details, you can read some source code or contact me!

This is what I did and my gradle build speed improved dramatically! from 1 min to 20sec for the first build and succeeding builds became from 40 sec to 5 sec.

In the gradle.properties file Add this:

org.gradle.jvmargs=-Xmx8192M -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

In the Command Line Arguments via Go to File > Other Settings> default Settings >Build, Execution, Deploy> Complier and add the following arguments to Command Line Arguments

Add this:

--debug --stacktrace -a, --no-rebuild -q, --quiet --offline

As mentioned in a more recent answer, the preferred way is now simply:

const homedir = require('os').homedir();

[Original Answer]: Why not use the USERPROFILE environment variable on win32?

function getUserHome() {
  return process.env[(process.platform == 'win32') ? 'USERPROFILE' : 'HOME'];
}

Since this question is top google result, I will add another possible thing to the list.

If the module that you're using has a failure on the dependency injection wrapper, it will provide this same result. For example copy & paste modules from the internet may rely on underscore.js and attempt to inject with '_' in the di wrapper. If underscore doesn't exist in your project dependency providers, when your controller attempts to reference your module's factory, it will get 'unknown provider' for your factory in the browser's console log.

You commented: not working if oldtable has an identity column.

I think that's your answer. The #newtable gets an identity column from the oldtable automatically. Run the next statements:

create table oldtable (id int not null identity(1,1), v varchar(10) )

select * into #newtable from oldtable

use tempdb
GO
sp_help #newtable

It shows you that #newtable does have the identity column.

If you don't want the identity column, try this at creation of #newtable:

select id + 1 - 1 as nid, v, IDENTITY( int ) as id into #newtable
     from oldtable

VLookup

You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".

External Reference

To reference a cell of the same Workbook use the following pattern:

<Sheetname>!<Cell>

Example:

Table1!A1

To reference a cell of a different Workbook use this pattern:

[<Workbook_name>]<Sheetname>!<Cell>

Example:

[MyWorkbook]Table1!A1

I'll leave it here in case anyone will face the same issue. I had to put a ListView inside a ScrollView. ListView with header was not an option by a number of reasons. Neither was an option to use LinearLayout instead of ListView. So I followed the accepted solution, but it didn't work because items in the list had complex layout with multiple rows and each listview item was of variable height. Height was measured not properly. The solution was to measure each item inside ListView Adapter's getView() method.

@Override
public View getView(int position, View view, ViewGroup parent) {
    ViewHolder holder;
    if (view == null) {
        . . .
        view.setTag(holder);
    } else holder = (ViewHolder)view.getTag();
    . . .

    // measure ListView item (to solve 'ListView inside ScrollView' problem)
    view.measure(View.MeasureSpec.makeMeasureSpec(
                    View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED),
            View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));
    return view;
}

It seems there must be at least one local commit on the master branch to do:

git push -u origin master

So if you did git init . and then git remote add origin ..., you still need to do:

git add ...
git commit -m "..."

std::less<> when using custom classes with operator<

If you are dealing with a set of your custom class that has operator< defined, then you can just use std::less<>.

As mentioned at http://en.cppreference.com/w/cpp/container/set/find C++14 has added two new find APIs:

template< class K > iterator find( const K& x );
template< class K > const_iterator find( const K& x ) const;

which allow you to do:

main.cpp

#include <cassert>
#include <set>

class Point {
    public:
        // Note that there is _no_ conversion constructor,
        // everything is done at the template level without
        // intermediate object creation.
        //Point(int x) : x(x) {}
        Point(int x, int y) : x(x), y(y) {}
        int x;
        int y;
};
bool operator<(const Point& c, int x) { return c.x < x; }
bool operator<(int x, const Point& c) { return x < c.x; }
bool operator<(const Point& c, const Point& d) {
    return c.x < d;
}

int main() {
    std::set<Point, std::less<>> s;
    s.insert(Point(1, -1));
    s.insert(Point(2, -2));
    s.insert(Point(0,  0));
    s.insert(Point(3, -3));
    assert(s.find(0)->y ==  0);
    assert(s.find(1)->y == -1);
    assert(s.find(2)->y == -2);
    assert(s.find(3)->y == -3);
    // Ignore 1234, find 1.
    assert(s.find(Point(1, 1234))->y == -1);
}

Compile and run:

g++ -std=c++14 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

More info about std::less<> can be found at: What are transparent comparators?

Tested on Ubuntu 16.10, g++ 6.2.0.

You cannot add methods to an existing type unless the existing type is marked as partial, you can only add methods that appear to be a member of the existing type through extension methods. Since this is the case you cannot add static methods to the type itself since extension methods use instances of that type.

There is nothing stopping you from creating your own static helper method like this:

static class DateTimeHelper
{
    public static DateTime Tomorrow
    {
        get { return DateTime.Now.AddDays(1); }
    }
}

Which you would use like this:

DateTime tomorrow = DateTimeHelper.Tomorrow;

The issue is quite simple: one or more of the columns in the source query contains data that exceeds the length of its destination column. A simple solution would be to take your source query and execute Max(Len( source col )) on each column. I.e.,

Select Max(Len(TextCol1))
    , Max(Len(TextCol2))
    , Max(Len(TextCol3))
    , ...
From ...

Then compare those lengths to the data type lengths in your destination table. At least one, exceeds its destination column length.

If you are absolutely positive that this should not be the case and do not care if it is not the case, then another solution is to forcibly cast the source query columns to their destination length (which will truncate any data that is too long):

Select Cast(TextCol1 As varchar(...))
    , Cast(TextCol2 As varchar(...))
    , Cast(TextCol3 As varchar(...))
    , ...
From ...

In JDK7, "more NIO features" should have methods to apply the visitor pattern over a file tree or just the immediate contents of a directory - no need to find all the files in a potentially huge directory before iterating over them.

listOfCatalogIDs =[@[@"id[]=",listOfCatalogIDs] componentsJoinedByString:@""];

If start can't find what it's looking for, it does what you describe.

Since what you're doing should work, it's very likely you're leaving out some quotes (or putting extras in).

You can use

val drawableCompat = ContextCompat.getDrawable(context, R.drawable.ic_emoticon_happy)

or in java java

Drawable drawableCompat = ContextCompat.getDrawable(getContext(), R.drawable.ic_emoticon_happy)

#include<stdio.h>

int main() {
int num; //given integer
int reminder;
int rev=0; //To reverse the given integer
int count=1;

printf("Enter the integer:");
scanf("%i",&num);

/*First while loop will reverse the number*/
while(num!=0)
{
    reminder=num%10;
    rev=rev*10+reminder;
    num/=10;
}
/*Second while loop will give the number from left to right*/
while(rev!=0)
{
    reminder=rev%10;
    printf("The %d digit is %d\n",count, reminder);
    rev/=10;
    count++; //to give the number from left to right 
}
return (EXIT_SUCCESS);}

You can use the following:

    /// <summary>
    /// Serializes an object.
    /// </summary>
    /// <typeparam name="T"></typeparam>
    /// <param name="serializableObject"></param>

    public void SerializeObject<T>(T serializableObject, string fileName)
    {
        if (serializableObject == null) { return; }

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            XmlSerializer serializer = new XmlSerializer(serializableObject.GetType());
            using (MemoryStream stream = new MemoryStream())
            {
                serializer.Serialize(stream, serializableObject);
                stream.Position = 0;
                xmlDocument.Load(stream);
                xmlDocument.Save(fileName);
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }
    }

    public T DeSerializeObject<T>(string fileName)
    {
        if (string.IsNullOrEmpty(fileName)) { return default(T); }

        T objectOut = default(T);

        try
        {
            XmlDocument xmlDocument = new XmlDocument();
            xmlDocument.Load(fileName);
            string xmlString = xmlDocument.OuterXml;

            using (StringReader read = new StringReader(xmlString))
            {
                Type outType = typeof(T);

                XmlSerializer serializer = new XmlSerializer(outType);
                using (XmlReader reader = new XmlTextReader(read))
                {
                    objectOut = (T)serializer.Deserialize(reader);
                }
            }
        }
        catch (Exception ex)
        {
            //Log exception here
        }

        return objectOut;
    }

You can't update more that one table in a single statement, however the error message you get is because of the aliases, you could try this :

BEGIN TRANSACTION

update A
set A.ORG_NAME =  @ORG_NAME
from table1 A inner join table2 B
on B.ORG_ID = A.ORG_ID
and A.ORG_ID = @ORG_ID

update B
set B.REF_NAME = @REF_NAME
from table2 B inner join table1 A
    on B.ORG_ID = A.ORG_ID
    and A.ORG_ID = @ORG_ID

COMMIT

In my opinion, if you're likely to often modify those large files, or if you intend to make a lot of git clone or git checkout, then you should seriously consider using another Git repository (or maybe another way to access those files).

But if you work like we do, and if your binary files are not often modified, then the first clone/checkout will be long, but after that it should be as fast as you want (considering your users keep using the first cloned repository they had).

this should help you

One solution is adding pyspark-shell to the shell environment variable PYSPARK_SUBMIT_ARGS:

export PYSPARK_SUBMIT_ARGS="--master local[2] pyspark-shell"

There is a change in python/pyspark/java_gateway.py , which requires PYSPARK_SUBMIT_ARGS includes pyspark-shell if a PYSPARK_SUBMIT_ARGS variable is set by a user.

Below solution tested and its working, hope it will support in your project.
HTML code:
    <input type="file" name="asgnmnt_file" id="asgnmnt_file" class="span8" 
    style="display:none;" onchange="fileSelected(this)">
    <br><br>
    <img id="asgnmnt_file_img" src="uploads/assignments/abc.jpg" width="150" height="150" 
    onclick="passFileUrl()" style="cursor:pointer;">

JavaScript code:
    function passFileUrl(){
    document.getElementById('asgnmnt_file').click();
    }

    function fileSelected(inputData){
    document.getElementById('asgnmnt_file_img').src = window.URL.createObjectURL(inputData.files[0])
    }

I got one good solution. Here I have attached it as the image below. So try it. It may be helpful to you...!

This function is using yield:

function a($items) {
    foreach ($items as $item) {
        yield $item + 1;
    }
}

It is almost the same as this one without:

function b($items) {
    $result = [];
    foreach ($items as $item) {
        $result[] = $item + 1;
    }
    return $result;
}

The only one difference is that a() returns a generator and b() just a simple array. You can iterate on both.

Also, the first one does not allocate a full array and is therefore less memory-demanding.

To crop retina images while keeping the same scale and orientation, use the following method in a UIImage category (iOS 4.0 and above):

- (UIImage *)crop:(CGRect)rect {
    if (self.scale > 1.0f) {
        rect = CGRectMake(rect.origin.x * self.scale,
                          rect.origin.y * self.scale,
                          rect.size.width * self.scale,
                          rect.size.height * self.scale);
    }

    CGImageRef imageRef = CGImageCreateWithImageInRect(self.CGImage, rect);
    UIImage *result = [UIImage imageWithCGImage:imageRef scale:self.scale orientation:self.imageOrientation];
    CGImageRelease(imageRef);
    return result;
}

I don't know what kind of homework this is, but most probably the teacher doesn't want an answer where you just call a "magical" existing function (even though that's the recommended way to do it), but he wants to see if you can implement this by your own.

Back in the days, my teacher used to say something like "I want to see if you can program by yourself, not if you can find it in the system." Well, how wrong he was ;) ..

Anyway, if your teacher is the same, here is the hard way to do it..

std::string LongToString(long value)
{
  std::string output;
  std::string sign;

  if(value < 0)
  {
    sign + "-";
    value = -value;
  }

  while(output.empty() || (value > 0))
  {
    output.push_front(value % 10 + '0')
    value /= 10;
  }

  return sign + output;
}

You could argue that using std::string is not "the hard way", but I guess what counts in the actual agorithm.

lines is a list of strings, re.findall doesn't work with that. try:

import re, sys

f = open('findallEX.txt', 'r')
lines = f.read()
match = re.findall('[A-Z]+', lines)
print match

I believe this excerpt from the Apache documentation, complements well the previous answers :

This directive is required when you use a relative path in a substitution in per-directory (htaccess) context unless either of the following conditions are true:

• The original request, and the substitution, are underneath the DocumentRoot (as opposed to reachable by other means, such as Alias).

• The filesystem path to the directory containing the RewriteRule, suffixed by the relative substitution is also valid as a URL path on the server (this is rare).

As previously mentioned, in other contexts, it is only useful to make your rule shorter. Moreover, also as previously mentioned, you can achieve the same thing by placing the htaccess file in the subdirectory.

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

I was having following issues for @Lalit Kumars answer,

ORA-19202: Error occurred in XML processing
ORA-00904: "SUCCESS": invalid identifier
ORA-06512: at "SYS.DBMS_XMLGEN", line 288
ORA-06512: at line 1
19202. 00000 -  "Error occurred in XML processing%s"
*Cause:    An error occurred when processing the XML function
*Action:   Check the given error message and fix the appropriate problem

Solution is:

WITH  char_cols AS
  (SELECT /*+materialize */ table_name, column_name
   FROM   cols
   WHERE  data_type IN ('CHAR', 'VARCHAR2'))
SELECT DISTINCT SUBSTR (:val, 1, 11) "Searchword",
       SUBSTR (table_name, 1, 14) "Table",
       SUBSTR (column_name, 1, 14) "Column"
FROM   char_cols,
       TABLE (xmlsequence (dbms_xmlgen.getxmltype ('select "'
       || column_name
       || '" from "'
       || table_name
       || '" where upper("'
       || column_name
       || '") like upper(''%'
       || :val
       || '%'')' ).extract ('ROWSET/ROW/*') ) ) t
ORDER  BY "Table"
/ 

I got the same error: SyntaxError: can't assign to literal when I was trying to assign multiple variables in a single line.

I was assigning the values as shown below:

    score = 0, isDuplicate = None

When I shifted them to another line, it got resolved:

    score = 0
    isDuplicate = None

I don't know why python does not allow multiple assignments at the same line but that's how it is done.

There is one more way to asisgn it in single line ie. Separate them with a semicolon in place of comma. Check the code below:

score = 0 ; duplicate = None

It may be worth noting that auto-indent does not work if there are syntax errors in the document. Get rid of the red squigglies, and THEN try CTRL+K, CTRL+D, whatever...

If you are using laravel 5 or 6:

1. Inside Public folder create .css, .js, images... folders

2. Then inside your blade file you can display an images using this code :

<link rel="stylesheet" href="/css/bootstrap.min.css">
<link src="/images/test.png">
<!-- / is important and dont write public folder-->

The shortest way is to directly add the below code as additional attributes in the input type that you want to change.

onfocus="if(this.value=='Search')this.value=''" 
onblur="if(this.value=='')this.value='Search'"

Please note: Change the text "Search" to "go" or any other text to suit your requirements.

You can just delete that directory that you cloned the repo into, and re-clone it wherever you'd like.

I don't think you can both within the same jenkins job, what you need to do is to configure a new jenkins job which will have access to your github to retrieve branches and then you can choose which one to manually build.

Just mark it as a parameterized build, specify a name, and a parameter configured as git parameter

and now you can configure git options:

My answer is little late but simple; but may help someone in future; I did experiment with angular versions such as 4.4.3, 5.1+, 6.x, 7.x, 8.x, 9.x and 10.x using $event (latest at the moment)

Template:

<select (change)="onChange($event)">
    <option *ngFor="let v of values" [value]="v.id">{{v.name}}</option>
</select>

TS

export class MyComponent {
  public onChange(event): void {  // event will give you full breif of action
    const newVal = event.target.value;
    console.log(newVal);
  }
}

You can add the following lines to build.gradle, **/* excludes all the tests.

test {
    exclude '**/*'
}

Incase of arrays, the base address (i.e. address of the array) is the address of the 1st element in the array. Also the array name acts as a pointer.

Consider a row of houses (each is an element in the array). To identify the row, you only need the 1st house address.You know each house is followed by the next (sequential).Getting the address of the 1st house, will also give you the address of the row.

Incase of string literals(character arrays defined at declaration), they are automatically appended by \0.

printf prints using the format specifier and the address provided. Since, you use %s it prints from the 1st address (incrementing the pointer using arithmetic) until '\0'

IMPORTANT NOTE: You should not concatenate SQL queries unless you trust the user completely. Query concatenation involves risk of SQL Injection being used to take over the world, ...khem, your database.

If you don't want to go into details how to execute query using SqlCommand then you could call the same command line like this:

string userInput = "Brian";
var process = new Process();
var startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = string.Format(@"sqlcmd.exe -S .\PDATA_SQLEXPRESS -U sa -P 2BeChanged! -d PDATA_SQLEXPRESS  
     -s ; -W -w 100 -Q "" SELECT tPatCulIntPatIDPk, tPatSFirstname, tPatSName,
     tPatDBirthday  FROM  [dbo].[TPatientRaw] WHERE tPatSName = '{0}' """, userInput);

process.StartInfo = startInfo;
process.Start();

Just ensure that you escape each double quote " with ""

In my case, I'm using POJO. And I forgot configure POJOMappingFeature as true. Maycon has pointed it out in an early answer. However some guys might have trouble to configure it in web.xml correctly, here is my example.

<servlet>
    <servlet-name>Jersey Servlet</servlet-name>
    <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
        <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Here you can find Postgre example, this code run multiple sql commands (update 2 columns) within single SQL connection

public static class SQLTest
    {
        public static void NpgsqlCommand()
        {
            using (NpgsqlConnection connection = new NpgsqlConnection("Server = ; Port = ; User Id = ; " + "Password = ; Database = ;"))
            {
                NpgsqlCommand command1 = new NpgsqlCommand("update xy set xw = 'a' WHERE aa='bb'", connection);
                NpgsqlCommand command2 = new NpgsqlCommand("update xy set xw = 'b' where bb = 'cc'", connection);
                command1.Connection.Open();
                command1.ExecuteNonQuery();
                command2.ExecuteNonQuery();
                command2.Connection.Close();
            }
        }
    }

Quick & Simple Solution: I faced this problem with Microsoft.AspNet.Mvc -Version 5.2.3 and after going through all these threads I found a simplest solution.

Just follow steps:

1. Open NuGet Package Manager in Visual studio for your project
2. Search for Microsoft.AspNet.Mvc
3. When found, change action to Uninstall and Uninstall it
4. Once done, install it again and try it now

This will automatically fix all issues with references. See image below:

The contract of the hash code makes clear that:

"If two objects are equal according to the Object method, then calling the hashCode method on each of the two objects must produce the same integer result."

So your assumption:

"To clarify, the equals method is overridden, but it only checks one of the fields, not all. So two Foo objects that are considered equal can actually have different values, that's why I can't just use foo."

is wrong and you are breaking the contract. If we look at the "contains" method of Set interface, we have that:

boolean contains(Object o);
Returns true if this set contains the specified element. More formally, returns true if and only if this set contains an element "e" such that o==null ? e==null : o.equals(e)

To accomplish what you want, you can use a Map where you define the key and store your element with the key that defines how objects are different or equal to each other.

You have a couple of problems here.

First, the XSD has an issue where an element is both named or referenced; in your case should be referenced.

Change:

<xsd:element name="stock" ref="Stock" minOccurs="1" maxOccurs="unbounded"/> 

To:

<xsd:element name="stock" type="Stock" minOccurs="1" maxOccurs="unbounded"/> 

And:

• Remove the declaration of the global element Stock
• Create a complex type declaration for a type named Stock

So:

<xsd:element name="Stock">
    <xsd:complexType>

To:

<xsd:complexType name="Stock">

Make sure you fix the xml closing tags.

The second problem is that the correct way to reference an external XSD is to use XSD schema with import/include within a wsdl:types element. wsdl:import is reserved to referencing other WSDL files. More information is available by going through the WS-I specification, section WSDL and Schema Import. Based on WS-I, your case would be:

INCORRECT: (the way you showed it)

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <import namespace="http://stock.com/schemas/services/stock" location="Stock.xsd" />
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

CORRECT:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://stock.com/schemas/services/stock" schemaLocation="Stock.xsd" />             
        </schema>
    </types>
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

SOME processors may support both syntaxes. The XSD you put out shows issues, make sure you first validate the XSD.

It would be better if you go the WS-I way when it comes to WSDL authoring.

Other issues may be related to the use of relative vs. absolute URIs in locating external content.

Ok, this might be either a hack or error-prone, but somehow this is working as well-

SELECT id, MAX(user) as user, MAX(time) as time, MAX(io) as io FROM lms_attendance GROUP BY id;

It varies for different systems (depends on RAM). The easiest way to find out is

import six six.MAXSIZE 9223372036854775807 This gives the max size of list and dict too ,as per the documentation

SwiftUI - Full Example

import SwiftUI

struct ContentView: View {
    
    @State private var text = defaultText
    
    @State private var isKeyboardShowing = false
    
    private static let defaultText = "write something..."
    
    private var gesture = TapGesture().onEnded({_ in
        UIApplication.shared.endEditing(true)
    })
    
    var body: some View {
        
        ZStack {
            Color.black
            
            VStack(alignment: .leading) {
                TextField("placeholder", text: $text)
                    .foregroundColor(.white)
                    .padding()
                    .background(Color.green)
            }
            
            .padding()
        }
        .edgesIgnoringSafeArea(.all)
        .onChange(of: isKeyboardShowing, perform: { (isShowing) in
            if isShowing {
                if text == Self.defaultText { text = "" }
            } else {
                if text == "" { text = Self.defaultText }
            }
        })
        .simultaneousGesture(gesture)
        .onReceive(NotificationCenter.default
                    .publisher(for: UIResponder.keyboardWillShowNotification), perform: { (value) in
                        isKeyboardShowing = true
                    })
        .onReceive(NotificationCenter.default
                    .publisher(for: UIResponder.keyboardWillHideNotification), perform: { (value) in
                        isKeyboardShowing = false
                    })
    }
}

extension UIApplication {
    func endEditing(_ force: Bool) {
        self.windows
            .filter{$0.isKeyWindow}
            .first?
            .endEditing(force)
    }
}

I had the same issue. I wanted to send data via POST. I used the following code:

    URL url = new URL("http://example.com/getval.php");
    Map<String,Object> params = new LinkedHashMap<>();
    params.put("param1", param1);
    params.put("param2", param2);

    StringBuilder postData = new StringBuilder();
    for (Map.Entry<String,Object> param : params.entrySet()) {
        if (postData.length() != 0) postData.append('&');
        postData.append(URLEncoder.encode(param.getKey(), "UTF-8"));
        postData.append('=');
        postData.append(URLEncoder.encode(String.valueOf(param.getValue()), "UTF-8"));
    }
    String urlParameters = postData.toString();
    URLConnection conn = url.openConnection();

    conn.setDoOutput(true);

    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

    writer.write(urlParameters);
    writer.flush();

    String result = "";
    String line;
    BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));

    while ((line = reader.readLine()) != null) {
        result += line;
    }
    writer.close();
    reader.close()
    System.out.println(result);

I used Jsoup for parse:

    Document doc = Jsoup.parseBodyFragment(value);
    Iterator<Element> opts = doc.select("option").iterator();
    for (;opts.hasNext();) {
        Element item = opts.next();
        if (item.hasAttr("value")) {
            System.out.println(item.attr("value"));
        }
    }

Cross Browser jQuery Solution! _{Raw available at GitHub}

Fun & Easy to Use!

The following plugin will go through your standard test for various versions of IE, Chrome, Firefox, Safari, etc.. and establish your declared methods accordingly. It also deals with issues such as:

• onblur|.blur/onfocus|.focus "duplicate" calls
• window losing focus through selection of alternate app, like word
• • This tends to be undesirable simply because, if you have a bank page open, and it's onblur event tells it to mask the page, then if you open calculator, you can't see the page anymore!
• Not triggering on page load

Use is as simple as: _{Scroll Down to 'Run Snippet'}

$.winFocus(function(event, isVisible) {
    console.log("Combo\t\t", event, isVisible);
});

//  OR Pass False boolean, and it will not trigger on load,
//  Instead, it will first trigger on first blur of current tab_window
$.winFocus(function(event, isVisible) {
    console.log("Combo\t\t", event, isVisible);
}, false);

//  OR Establish an object having methods "blur" & "focus", and/or "blurFocus"
//  (yes, you can set all 3, tho blurFocus is the only one with an 'isVisible' param)
$.winFocus({
    blur: function(event) {
        console.log("Blur\t\t", event);
    },
    focus: function(event) {
        console.log("Focus\t\t", event);
    }
});

//  OR First method becoms a "blur", second method becoms "focus"!
$.winFocus(function(event) {
    console.log("Blur\t\t", event);
},
function(event) {
    console.log("Focus\t\t", event);
});

Few steps that helped me (some of them are mentioned above):

Open project structure by:

command + ; (mac users) OR right click on the project -> Open Module Settings

1. Facets -> + -> Python -> <your-project> -> OK
2. Modules -> Python -> <select python interpreter>
3. Project -> Project SDK -> <select relevant SDK>
4. SDKs -> <make sure it's the right one>

Click OK.

Open Run/Debug Configurations by: Run -> Edit Configurations

5. Python Interpreter -> <make sure it's the right one>

Click OK.

for 1D and 2D arrays you can use np.savetxt to print using a specific format string:

>>> import sys
>>> x = numpy.arange(20).reshape((4,5))
>>> numpy.savetxt(sys.stdout, x, '%5.2f')
 0.00  1.00  2.00  3.00  4.00
 5.00  6.00  7.00  8.00  9.00
10.00 11.00 12.00 13.00 14.00
15.00 16.00 17.00 18.00 19.00

Your options with numpy.set_printoptions or numpy.array2string in v1.3 are pretty clunky and limited (for example no way to suppress scientific notation for large numbers). It looks like this will change with future versions, with numpy.set_printoptions(formatter=..) and numpy.array2string(style=..).

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

For windows, Use the Anaconda Powershell Prompt

I might have a solution for the video as background, stretched to the browser-width or height, (but the video will still preserve the aspect ratio, couldnt find a solution for that yet.):

Put the video right after the body-tag with style="width:100%;". Right afterwords, put a "bodydummy"-tag:

<body>
<video id="bgVideo" autoplay poster="videos/poster.png">
    <source src="videos/test-h264-640x368-highqual-winff.mp4" type="video/mp4"/>
    <source src="videos/test-640x368-webmvp8-miro.webm" type="video/webm"/>
    <source src="videos/test-640x368-theora-miro.ogv" type="video/ogg"/>    
</video>

<img id="bgImg" src="videos/poster.png" />

<!-- This image stretches exactly to the browser width/height and lies behind the video-->

<div id="bodyDummy">

Put all your content inside the bodydummy-div and put the z-indexes correctly in CSS like this:

#bgImg{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 1;
    width: 100%;
    height: 100%;
}

#bgVideo{ 
    position: absolute;
    top: 0;
    left: 0;
    border: 0;
    z-index: 2;
    width: 100%;
    height: 100%;
}

#bodyDummy{ 
    position: absolute;
    top: 0;
    left: 0;
    z-index: 3;
    overflow: auto;
    width: 100%;
    height: 100%;
}

Hope I could help. Let me know when you could find a solution that the video does not maintain the aspect ratio, so it could fill the whole browser window so we do not have to put a bgimage.

Either:

SELECT u_name AS user_name
FROM   users
WHERE  u_name = "john";

or:

SELECT user_name
from
(
SELECT u_name AS user_name
FROM   users
)
WHERE  u_name = "john";

The latter ought to be the same as the former if the RDBMS supports predicate pushing into the in-line view.

I had the same problem, and xmltable helped me:

Basically we had to enable TLS 1.2 for .NET 4.x. Making this registry changed worked for me, and stopped the event log filling up with the Schannel error.

More information on the answer can be found here

Linked Info Summary

Enable TLS 1.2 at the system (SCHANNEL) level:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Server]
"DisabledByDefault"=dword:00000000
"Enabled"=dword:00000001

(equivalent keys are probably also available for other TLS versions)

Tell .NET Framework to use the system TLS versions:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\.NETFramework\v4.0.30319]
"SystemDefaultTlsVersions"=dword:00000001

This may not be desirable for edge cases where .NET Framework 4.x applications need to have different protocols enabled and disabled than the OS does.

If you are trying to only serialize then pprint may also be a good option. It requires the object to be serialized and a file stream.

Here's some code:

from pprint import pprint
my_dict = {1:'a',2:'b'}
with open('test_results.txt','wb') as f:
    pprint(my_dict,f)

I am not sure if we can deserialize easily. I was using json to serialize and deserialze earlier which works correctly in most cases.

f.write(json.dumps(my_dict, sort_keys = True, indent = 2, ensure_ascii=True))

However, in one particular case, there were some errors writing non-unicode data to json.

There are many ways to scroll up and down in Selenium Webdriver I always use Java Script to do the same.

Below is the code which always works for me if I want to scroll up or down

 // This  will scroll page 400 pixel vertical
  ((JavascriptExecutor)driver).executeScript("scroll(0,400)");

You can get full code from here Scroll Page in Selenium

If you want to scroll for a element then below piece of code will work for you.

je.executeScript("arguments[0].scrollIntoView(true);",element);

You will get the full doc here Scroll for specific Element

Pending design decision. Meanwhile, use exclude()

The Django issue tracker has the remarkable entry #5763, titled "Queryset doesn't have a "not equal" filter operator". It is remarkable because (as of April 2016) it was "opened 9 years ago" (in the Django stone age), "closed 4 years ago", and "last changed 5 months ago".

Read through the discussion, it is interesting. Basically, some people argue __ne should be added while others say exclude() is clearer and hence __ne should not be added.

(I agree with the former, because the latter argument is roughly equivalent to saying Python should not have != because it has == and not already...)

ruby on rails notes has a very nice blogpost about commenting in erb-files

the short version is

to comment a single line use

<%# commented line %>

to comment a whole block use a if false to surrond your code like this

<% if false %>
code to comment
<% end %>

According SQL Server 2008 Books You can create local and global temporary tables. Local temporary tables are visible only in the current session, and global temporary tables are visible to all sessions.

'#table_temporal

'##table_global

If a local temporary table is created in a stored procedure or application that can be executed at the same time by several users, the Database Engine must be able to distinguish the tables created by the different users. The Database Engine does this by internally appending a numeric suffix to each local temporary table name.

Then there occurs no problem.

Adding to the above answers, I put the following lines in my .bash_profile (or .zshrc for MacOS 10.15+) which makes it really convenient to switch (including @elektromin's comment for java 9):

alias j12="export JAVA_HOME=`/usr/libexec/java_home -v 12`; java -version"
alias j11="export JAVA_HOME=`/usr/libexec/java_home -v 11`; java -version"
alias j10="export JAVA_HOME=`/usr/libexec/java_home -v 10`; java -version"
alias j9="export JAVA_HOME=`/usr/libexec/java_home -v 9`; java -version"
alias j8="export JAVA_HOME=`/usr/libexec/java_home -v 1.8`; java -version"
alias j7="export JAVA_HOME=`/usr/libexec/java_home -v 1.7`; java -version"

After inserting, execute $ source .bash_profile

I can switch to Java 8 by typing the following:

$ j8
java version "1.8.0_102"
Java(TM) SE Runtime Environment (build 1.8.0_102-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.102-b14, mixed mode)

The second top answer mentions ifeq, however, it fails to mention that these must be on the same level as the name of the target, e.g., to download a file only if it doesn't currently exist, the following code could be used:

download:
ifeq (,$(wildcard ./glob.c))
    curl … -o glob.c
endif

# THIS DOES NOT WORK!
download:
    ifeq (,$(wildcard ./glob.c))
        curl … -o glob.c
    endif

just

' '.join(a)

and write this output to a file.

Late to the party, but I think this addition might be useful for people working with rmarkdown. In rmarkdown there is built-in support for references to headers in your document.

Any header defined by

# Header

can be referenced by

get me back to that [header](#header)

The following is a minimal standalone .rmd file that shows this behavior. It can be knitted to .pdf and .html.

---
title: "references in rmarkdown"
output:
  html_document: default
  pdf_document: default
---

# Header

Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. Write some more text. 

Go back to that [header](#header).

yum install python-devel will work.

If yum doesn't work then use

apt-get install python-dev

In WinForms, ValueMember and DisplayMember are used when data-binding the list. If you're not data-binding, then you can add any arbitrary object as a ListItem.

The catch to that is that, in order to display the item, ToString() will be called on it. Thus, it is highly recommended that you only add objects to the ListBox where calling ToString() will result in meaningful output.

first import FormsModule and then use ngModel in your component.ts

import { FormsModule } from '@angular/forms';

@NgModule({
 imports: [ 
            FormsModule  
          ];

HTML Code:

<input type='text' [(ngModel)] ="usertext" />

You should add the target="_blank" and rel="noopener noreferrer" in the anchor tag.

For example:

<a target="_blank" rel="noopener noreferrer" href="http://your_url_here.html">Link</a>

Adding rel="noopener noreferrer" is not mandatory, but it's a recommended security measure. More information can be found in the links below.

Source:

• MDN | HTML element <a> | attribute target
• About rel=noopener
• Opens External Anchors Using rel="noopener"

There are two types in this parsing.

1. Parsing data from a file from a system path
2. Parsing JSON from remote URL.

From a file, you can use the following

import json
json = json.loads(open('/path/to/file.json').read())
value = json['key']
print json['value']

This arcticle explains the full parsing and getting values using two scenarios.Parsing JSON using Python

There are many excellent answers already, but let me give you one example:

I have an simple Item class:

 class Item
    {
    public: 
      std::string name;
      int weight;
      int price;
    };

I make a vector to hold a bunch of them.

std::vector<Item> inventory;

I create one million Item objects, and push them back onto the vector. I sort the vector by name, and then do a simple iterative binary search for a particular item name. I test the program, and it takes over 8 minutes to finish executing. Then I change my inventory vector like so:

std::vector<Item *> inventory;

...and create my million Item objects via new. The ONLY changes I make to my code are to use the pointers to Items, excepting a loop I add for memory cleanup at the end. That program runs in under 40 seconds, or better than a 10x speed increase. EDIT: The code is at http://pastebin.com/DK24SPeW With compiler optimizations it shows only a 3.4x increase on the machine I just tested it on, which is still considerable.

For a quick and lazy solution, (and not using VS at all) try these online converters:

• xsd-to-xml-converter here
• xmltocsharp converter here

XSD => XML => C# classes

Example XSD:

<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

<xs:element name="shiporder">
  <xs:complexType>
    <xs:sequence>
      <xs:element name="orderperson" type="xs:string"/>
      <xs:element name="shipto">
        <xs:complexType>
          <xs:sequence>
            <xs:element name="name" type="xs:string"/>

You either have to make the method Shared or use an instance of the class General:

Dim gen = New General()
gen.updateDynamics(get_prospect.dynamicsID)

or

General.updateDynamics(get_prospect.dynamicsID)

Public Shared Sub updateDynamics(dynID As Int32)
    ' ... '
End Sub

Marco Pellicciotta: The position of the element inside another element can be relative or absolute, about the element it's inside.

If you need to position the element in the browser window point of view it's best to use position:fixed

If you are on Python3 you can also use the library PILasOPENCV which works in Python 2 and 3. Function api calls are the same as in PIL or pillow but internally it works with OpenCV and numpy to load, save and manipulate images. Have a look at https://github.com/bunkahle/PILasOPENCV or install it with pip install PILasOPENCV. Not all PIL functions have been simulated but the most common functions work.

Out-File defaults to unicode encoding which is why you are seeing the behavior you are. Use -Encoding Ascii to change this behavior. In your case

Out-File -Encoding Ascii -append textfile.txt. 

Add-Content uses Ascii and also appends by default.

"This is a test" | Add-Content textfile.txt.

As for the lack of newline: You did not send a newline so it will not write one to file.

If you really mean any and ASCII (not e.g. all Unicode characters):

xxx[\x00-\x7F]+xxx

JavaScript example:

var re = /xxx[\x00-\x7F]+xxx/;

re.test('xxxabcxxx')
// true

re.test('xxx???xxx')
// false

Most answers here either require a clean working directory and multiple interactive steps (bad for scripting), or don't work for all cases, e.g. past merges which already bring some of the outstanding changes into your target branch, or cherry-picks doing the same.

To truly see what would change in the master branch if you merged develop into it, right now:

git merge-tree $(git merge-base master develop) master develop

As it's a plumbing command, it does not guess what you mean, you have to be explicit. It also doesn't colorize the output or use your pager, so the full command would be:

git merge-tree $(git merge-base master develop) master develop | colordiff | less -R

(thanks to David Normington for the link)

P.S.:

If you would get merge conflicts, they will show up with the usual conflict markers in the output, e.g.:

$ git merge-tree $(git merge-base a b ) a b 
added in both
  our    100644 78981922613b2afb6025042ff6bd878ac1994e85 a
  their  100644 61780798228d17af2d34fce4cfbdf35556832472 a
@@ -1 +1,5 @@
+<<<<<<< .our
 a
+=======
+b
+>>>>>>> .their

User @dreftymac makes a good point: this makes it unsuitable for scripting, because you can't easily catch that from the status code. The conflict markers can be quite different depending on circumstance (deleted vs modified, etc), which makes it hard to grep, too. Beware.

If X and beta do not have the same shape as the second term in the rhs of your last line (i.e. nsample), then you will get this type of error. To add an array to a tuple of arrays, they all must be the same shape.

I would recommend looking at the numpy broadcasting rules.

while (dr.Read())
{
    for (int i = 0; i < dr.FieldCount; i++)
    {
        subjob.Items.Add(dr[i]);
    }
}

If you install eslint under your local project, you should have a directory /node_modules/eslint/conf/ and under that directory a file eslint.json. You could edit the file and modify "no-console" entry with the value "off" (although 0 value is supported too):

"rules": {
    "no-alert": "off",
    "no-array-constructor": "off",
    "no-bitwise": "off",
    "no-caller": "off",
    "no-case-declarations": "error",
    "no-catch-shadow": "off",
    "no-class-assign": "error",
    "no-cond-assign": "error",
    "no-confusing-arrow": "off",
    "no-console": "off",
    ....

I hope this "configuration" could help you.
