Note however:

If you issue SET TRANSACTION ISOLATION LEVEL in a stored procedure or trigger, when the object returns control the isolation level is reset to the level in effect when the object was invoked. For example, if you set REPEATABLE READ in a batch, and the batch then calls a stored procedure that sets the isolation level to SERIALIZABLE, the isolation level setting reverts to REPEATABLE READ when the stored procedure returns control to the batch.

It is Safari specific, at least at time of writing, being introduced in Safari 9.0. From the "What's new in Safari?" documentation for Safari 9.0:

Viewport Changes

Viewport meta tags using "width=device-width" cause the page to scale down to fit content that overflows the viewport bounds. You can override this behavior by adding "shrink-to-fit=no" to your meta tag as shown below. The added value will prevent the page from scaling to fit the viewport.

<meta name="viewport" content="width=device-width, initial-scale=1.0, shrink-to-fit=no">

In short, adding this to the viewport meta tag restores pre-Safari 9.0 behaviour.

Example

Here's a worked visual example which shows the difference upon loading the page in the two configurations.

The red section is the width of the viewport and the blue section is positioned outside the initial viewport (eg left: 100vw). Note how in the first example the page is zoomed to fit when shrink-to-fit=no is omitted (thus showing the out-of-viewport content) and the blue content remains off screen in the latter example.

The code for this example can be found at https://codepen.io/davidjb/pen/ENGqpv.

Without shrink-to-fit specified

With shrink-to-fit=no

In the very right bottom corner, left to the smiley there was the icon saying "Plain Text". When you click it, the menu with all languages appears where you can choose your desired language.

You can try with this code to maximize chrome window.

ChromeOptions options = new ChromeOptions();
options.addArguments("--window-size=1920,1080");

WebDriver driver = new ChromeDriver(options);

Go to resources folder where the application.properties is present, update the below code in that.

spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration

For VB6:

You need to declare your C functions as __stdcall, otherwise you get "invalid calling convention" type errors. About other your questions:

can I take arguments by pointer/reference from the VB front-end?

Yes, use ByRef/ByVal modifiers.

Can the DLL call a theoretical function in the front-end?

Yes, use AddressOf statement. You need to pass function pointer to dll before.

Or have a function take a "function pointer" (I don't even know if that's possible) from VB and call it?)

Yes, use AddressOf statement.

update (more questions appeared :)):

to load it into VB, do I just do the usual method (what I would do to load winsock.ocx or some other runtime, but find my DLL instead) or do I put an API call into a module?

You need to decaler API function in VB6 code, like next:

Private Declare Function SHGetSpecialFolderLocation Lib "shell32" _
   (ByVal hwndOwner As Long, _
    ByVal nFolder As Long, _
    ByRef pidl As Long) As Long

Based on the accepted answer by delnan.

What if one of your wanted keys aren't in the old_dict? The delnan solution will throw a KeyError exception that you can catch. If that's not what you need maybe you want to:

1. only include keys that excists both in the old_dict and your set of wanted_keys.

   old_dict = {'name':"Foobar", 'baz':42}
   wanted_keys = ['name', 'age']
   new_dict = {k: old_dict[k] for k in set(wanted_keys) & set(old_dict.keys())}
   
   >>> new_dict
   {'name': 'Foobar'}
   

2. have a default value for keys that's not set in old_dict.

   default = None
   new_dict = {k: old_dict[k] if k in old_dict else default for k in wanted_keys}
   
   >>> new_dict
   {'age': None, 'name': 'Foobar'}
   

Long options can be parsed by the standard getopts builtin as “arguments” to the - “option”

This is portable and native POSIX shell – no external programs or bashisms are needed.

This guide implements long options as arguments to the - option, so --alpha is seen by getopts as - with argument alpha and --bravo=foo is seen as - with argument bravo=foo. The true argument can be harvested with a simple replacement: ${OPTARG#*=}.

In this example, -b and -c (and their long forms, --bravo and --charlie) have mandatory arguments. Arguments to long options come after equals signs, e.g. --bravo=foo (space delimiters for long options would be hard to implement, see below).

Because this uses the getopts builtin, this solution supports usage like cmd --bravo=foo -ac FILE (which has combined options -a and -c and interleaves long options with standard options) while most other answers here either struggle or fail to do that.

die() { echo "$*" >&2; exit 2; }  # complain to STDERR and exit with error
needs_arg() { if [ -z "$OPTARG" ]; then die "No arg for --$OPT option"; fi; }

while getopts ab:c:-: OPT; do
  # support long options: https://stackoverflow.com/a/28466267/519360
  if [ "$OPT" = "-" ]; then   # long option: reformulate OPT and OPTARG
    OPT="${OPTARG%%=*}"       # extract long option name
    OPTARG="${OPTARG#$OPT}"   # extract long option argument (may be empty)
    OPTARG="${OPTARG#=}"      # if long option argument, remove assigning `=`
  fi
  case "$OPT" in
    a | alpha )    alpha=true ;;
    b | bravo )    needs_arg; bravo="$OPTARG" ;;
    c | charlie )  needs_arg; charlie="$OPTARG" ;;
    ??* )          die "Illegal option --$OPT" ;;  # bad long option
    ? )            exit 2 ;;  # bad short option (error reported via getopts)
  esac
done
shift $((OPTIND-1)) # remove parsed options and args from $@ list

When the option is a dash (-), it is a long option. getopts will have parsed the actual long option into $OPTARG, e.g. --bravo=foo originally sets OPT='-' and OPTARG='bravo=foo'. The if stanza sets $OPT to the contents of $OPTARG before the first equals sign (bravo in our example) and then removes that from the beginning of $OPTARG (yielding =foo in this step, or an empty string if there is no =). Finally, we strip the argument's leading =. At this point, $OPT is either a short option (one character) or a long option (2+ characters).

The case then matches either short or long options. For short options, getopts automatically complains about options and missing arguments, so we have to replicate those manually using the needs_arg function, which fatally exits when $OPTARG is empty. The ??* condition will match any remaining long option (? matches a single character and * matches zero or more, so ??* matches 2+ characters), allowing us to issue the "Illegal option" error before exiting.

Minor bug: if somebody gives an invalid single-character long option (and it's not also a short option), this will exit with an error but without a message. This is because this implementation assumes it was a short option. You could track that with an extra variable in the long option stanza preceding the case and then test for it in the final case condition, but I consider that too much of a corner case to bother.

(A note about all-uppercase variable names: Generally, the advice is to reserve all-uppercase variables for system use. I'm keeping $OPT as all-uppercase to keep it in line with $OPTARG, but this does break that convention. I think it fits because this is something the system should have done, and it should be safe because there are no standards (afaik) that use such a variable.)

To complain about unexpected arguments to long options, mimic what we did for mandatory arguments: use a helper function. Just flip the test around to complain about an argument when one isn't expected:

no_arg() { if [ -n "$OPTARG" ]; then die "No arg allowed for --$OPT option"; fi; }

An older version of this answer had an attempt at accepting long options with space-delimited arguments, but it was not reliable; getopts could prematurely terminate on the assumption that the argument was beyond its scope and manually incrementing $OPTIND doesn't work in all shells.

This would be accomplished using one of these techniques depending on your shell:

• POSIX eval: eval "bravo=\"\$$OPTIND\""
• Bash indirect expansion: bravo="${!OPTIND}"
• Zsh parameter expansion P flag: bravo="${(P)OPTIND}"

and then concluded with something like [ $# -gt $OPTIND ] && OPTIND=$((OPTIND+1))

If your code is prepared to deal with overflow errors, you can throw an exception if data is too large.

size_t data = 99999999;
if ( data > INT_MAX )
{
   throw std::overflow_error("data is larger than INT_MAX");
}
int convertData = static_cast<int>(data);

#'re.IGNORECASE' for case insensitive results short form re.I
#'re.match' returns the first match located from the start of the string. 
#'re.search' returns location of the where the match is found 
#'re.compile' creates a regex object that can be used for multiple matches

 >>> s = r'TeSt'   
 >>> print (re.match(s, r'test123', re.I))
 <_sre.SRE_Match object; span=(0, 4), match='test'>
 # OR
 >>> pattern = re.compile(s, re.I)
 >>> print(pattern.match(r'test123'))
 <_sre.SRE_Match object; span=(0, 4), match='test'>

Just do a manual build on your solution.

If you are using local IIS try deleting the website registration in IIS manager and then recreating it manually.

based on https://stackoverflow.com/a/27891752/2642478

class Version(private val value: String) : Comparable<Version> {
    private val splitted by lazy { value.split("-").first().split(".").map { it.toIntOrNull() ?: 0 } }

    override fun compareTo(other: Version): Int {
        for (i in 0 until maxOf(splitted.size, other.splitted.size)) {
            val compare = splitted.getOrElse(i) { 0 }.compareTo(other.splitted.getOrElse(i) { 0 })
            if (compare != 0)
                return compare
        }
        return 0
    }
}

you can use like:

    System.err.println(Version("1.0").compareTo( Version("1.0")))
    System.err.println(Version("1.0") < Version("1.1"))
    System.err.println(Version("1.10") > Version("1.9"))
    System.err.println(Version("1.10.1") > Version("1.10"))
    System.err.println(Version("0.0.1") < Version("1"))

You are correct in thinking that display is not animatable. It won't work, and you shouldn't bother including it in keyframe animations.

visibility is technically animatable, but in a round about way. You need to hold the property for as long as needed, then snap to the new value. visibility doesn't tween between keyframes, it just steps harshly.

.ele {_x000D_
  width: 60px;_x000D_
  height: 60px;_x000D_
  _x000D_
  background-color: #ff6699;_x000D_
  animation: 1s fadeIn;_x000D_
  animation-fill-mode: forwards;_x000D_
  _x000D_
  visibility: hidden;_x000D_
}_x000D_
_x000D_
.ele:hover {_x000D_
  background-color: #123;_x000D_
}_x000D_
_x000D_
@keyframes fadeIn {_x000D_
  99% {_x000D_
    visibility: hidden;_x000D_
  }_x000D_
  100% {_x000D_
    visibility: visible;_x000D_
  }_x000D_
}

<div class="ele"></div>

If you want to fade, you use opacity. If you include a delay, you'll need visibility as well, to stop the user from interacting with the element while it's not visible.

.ele {_x000D_
  width: 60px;_x000D_
  height: 60px;_x000D_
  _x000D_
  background-color: #ff6699;_x000D_
  animation: 1s fadeIn;_x000D_
  animation-fill-mode: forwards;_x000D_
  _x000D_
  visibility: hidden;_x000D_
}_x000D_
_x000D_
.ele:hover {_x000D_
  background-color: #123;_x000D_
}_x000D_
_x000D_
@keyframes fadeIn {_x000D_
  0% {_x000D_
    opacity: 0;_x000D_
  }_x000D_
  100% {_x000D_
    visibility: visible;_x000D_
    opacity: 1;_x000D_
  }_x000D_
}

<div class="ele"></div>

Both examples use animation-fill-mode, which can hold an element's visual state after an animation ends.

You need to set useaccessibleheader attribute of the gridview to true and also then also specify a TableSection to be a header after calling the DataBind() method on you GridView object. So if your grid view is mygv

mygv.UseAccessibleHeader = True
mygv.HeaderRow.TableSection = TableRowSection.TableHeader

This should result in a proper formatted grid with thead and tbody tags

You can use header files.

Good practice.

You can create a file called player.h declare all functions that are need by other cpp files in that header file and include it when needed.

player.h

#ifndef PLAYER_H    // To make sure you don't declare the function more than once by including the header multiple times.
#define PLAYER_H

#include "stdafx.h"
#include <SFML/Graphics.hpp>

int playerSprite();

#endif

player.cpp

#include "player.h"  // player.h must be in the current directory. or use relative or absolute path to it. e.g #include "include/player.h"

int playerSprite(){
    sf::Texture Texture;
    if(!Texture.loadFromFile("player.png")){
        return 1;
    }
    sf::Sprite Sprite;
    Sprite.setTexture(Texture);
    return 0;
}

main.cpp

#include "stdafx.h"
#include <SFML/Graphics.hpp>
#include "player.h"            //Here. Again player.h must be in the current directory. or use relative or absolute path to it.

int main()
{
    // ...
    int p = playerSprite();  
    //...

Not such a good practice but works for small projects. declare your function in main.cpp

#include "stdafx.h"
#include <SFML/Graphics.hpp>
// #include "player.cpp"


int playerSprite();  // Here

int main()
{
    // ...   
    int p = playerSprite();  
    //...

Using map() and reduce():

function arraysEqual (a1, a2) {
    return a1 === a2 || (
        a1 !== null && a2 !== null &&
        a1.length === a2.length &&
        a1
            .map(function (val, idx) { return val === a2[idx]; })
            .reduce(function (prev, cur) { return prev && cur; }, true)
    );
}

If that number represents milliseconds, use the Date's constructor :

var myDate = new Date(1238540400000);

If you are restoring the folder don't forget to chown the files to mysql:mysql

chown -R mysql:mysql /var/lib/mysql-data

otherwise you will get errors when trying to drop a database or add new column etc..

and restart MySQL

service mysql restart

Semicolons can be used to one line two or more commands. They don't have to be used, but they aren't restricted.

The semicolon ( ; ) allows multiple statements on the single line given that neither statement starts a new code block.

In my case $(document).ready(function() was missing. Try this.

$(document).ready(function(){   
("#table tr").click(function(){
       $(this).addClass('selected').siblings().removeClass('selected');    
       var value=$(this).find('td:first').html();
       alert(value);    
    });
    $('.ok').on('click', function(e){
        alert($("#table tr.selected td:first").html());
    });
});

The simple answer is to turn off async. But that's the wrong thing to do. The correct answer is to re-think how you write the rest of your code.

Instead of writing this:

function functABC(){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        success: function(data) {
            return data;
        }
    });
}

function foo () {
    var response = functABC();
    some_result = bar(response);
    // and other stuff and
    return some_result;
}

You should write it like this:

function functABC(callback){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        success: callback
    });
}

function foo (callback) {
    functABC(function(data){
        var response = data;
        some_result = bar(response);
        // and other stuff and
        callback(some_result);
    })
}

That is, instead of returning result, pass in code of what needs to be done as callbacks. As I've shown, callbacks can be nested to as many levels as you have function calls.

A quick explanation of why I say it's wrong to turn off async:

Turning off async will freeze the browser while waiting for the ajax call. The user cannot click on anything, cannot scroll and in the worst case, if the user is low on memory, sometimes when the user drags the window off the screen and drags it in again he will see empty spaces because the browser is frozen and cannot redraw. For single threaded browsers like IE7 it's even worse: all websites freeze! Users who experience this may think you site is buggy. If you really don't want to do it asynchronously then just do your processing in the back end and refresh the whole page. It would at least feel not buggy.

You could probably just resort to

<img src="..." style="pointer-events: none;">

for some reason my error kept pointing to the "proxy" property in the config file. Which was misleading. During my troubleshooting I was trying different values for the proxy and https-proxy properties, but would only get the error stating to make sure the proxy config was set properly, and pointing to an older value.

Using, NPM CONFIG LS -L command lists all the properties and values in the config file. I was then able to see the value in question was matching the https-proxy, therefore using the https-proxy. So I changed the proxy (my company uses different ones) and then it worked. figured I would add this, as with these subtle confusing errors, every perspective on it helps.

        var mousedown = 0;
        $(function(){
            document.onmousedown = function(e){
                mousedown = mousedown | getWindowStyleButton(e);
                e = e || window.event;
                console.log("Button: " + e.button + " Which: " + e.which + " MouseDown: " + mousedown);
            }

            document.onmouseup = function(e){
                mousedown = mousedown ^ getWindowStyleButton(e);
                e = e || window.event;
                console.log("Button: " + e.button + " Which: " + e.which + " MouseDown: " + mousedown);
            }

            document.oncontextmenu = function(e){
                // to suppress oncontextmenu because it blocks
                // a mouseup when two buttons are pressed and 
                // the right-mouse button is released before
                // the other button.
                return false;
            }
        });

        function getWindowStyleButton(e){
            var button = 0;
                if (e) {
                    if (e.button === 0) button = 1;
                    else if (e.button === 1) button = 4;
                    else if (e.button === 2) button = 2;  
                }else if (window.event){
                    button = window.event.button;
                }
            return button;
        }

this cross-browser version works fine for me.

Next to being in the wrong directory I just tripped about another variant:

I had a File.open(my_file).each {|line| puts line} exploding but there was something by that name in the directory I was working in (ls in the command line showed the name). I checked with a File.exists?(my_file) which strangely returned false. Explanation: my_file was a symlink which target didn't exist anymore! Since File.exists? will follow a symlink it will say false though the link is still there.

For the sake of completeness, since .NET 4.0 the code can rewritten as:

Guid.TryParse(queryString["web"], out WebId);

TryParse never throws exceptions and returns false if format is wrong, setting WebId to Guid.Empty.

Since C# 7 you can avoid introducing a variable on a separate line:

Guid.TryParse(queryString["web"], out Guid webId);

You can also create methods for parsing returning tuples, which aren't available in .NET Framework yet as of version 4.6:

(bool success, Guid result) TryParseGuid(string input) =>
    (Guid.TryParse(input, out Guid result), result);

And use them like this:

WebId = TryParseGuid(queryString["web"]).result;
// or
var tuple = TryParseGuid(queryString["web"]);
WebId = tuple.success ? tuple.result : DefaultWebId;

Next useless update to this useless answer comes when deconstruction of out-parameters is implemented in C# 12. :)

I think you wanted to do this:

while( $row = mysql_fetch_assoc( $result)){
    $new_array[] = $row; // Inside while loop
}

Or maybe store id as key too

 $new_array[ $row['id']] = $row;

Using the second ways you would be able to address rows directly by their id, such as: $new_array[ 5].

You can do it without having to create a real Hibernate mapping. Try this:

SELECT * FROM Employee e, Team t WHERE e.Id_team=t.Id_team

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

As strager suggests, look into using cURL. You may also be interested in setting CURLOPT_NOBODY with curl_setopt to skip downloading the whole page (you just want the headers).

As an additional reference for the other responses, instead of using "UTF-8" you can use:

HTTP.UTF_8

which is included since Java 4 as part of the org.apache.http.protocol library, which is included also since Android API 1.

One other way to work around this is using something like this when using mysqlclient in python.

suppose the data you want to enter is like this <ol><li><strong style="background-color: rgb(255, 255, 0);">Saurav\'s List</strong></li></ol>. It contains both double qoute and single quote.

You can use the following method to escape the quotes:

statement = """ Update chats set html='{}' """.format(html_string.replace("'","\\\'"))

Note: three \ characters are needed to escape the single quote which is there in unformatted python string.

Here's a good resource for wrapping columned lists. http://www.communitymx.com/content/article.cfm?cid=27f87

At least as of iOS 6, you can override methods in your custom cell to prevent the blue highlight. No other interaction is disabled or affected. All three must be overridden.

- (void) setHighlighted:(BOOL)highlighted
{
}

- (void) setHighlighted:(BOOL)highlighted animated:(BOOL)animated
{
}

- (void) setSelected:(BOOL)selected animated:(BOOL)animated
{
}

If you try to set the DataGrid.CellStyle the DataContext will be the row, so if you want to change the colour based on one cell it might be easiest to do so in specific columns, especially since columns can have varying contents, like TextBlocks, ComboBoxes and CheckBoxes. Here is an example of setting all the cells light-green where the Name is John:

<DataGridTextColumn Binding="{Binding Name}">
    <DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}">
            <Style.Triggers>
                <Trigger Property="Text" Value="John">
                    <Setter Property="Background" Value="LightGreen"/>
                </Trigger>
            </Style.Triggers>
        </Style>
    </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

You could also use a ValueConverter to change the colour.

public class NameToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        string input = value as string;
        switch (input)
        {
            case "John":
                return Brushes.LightGreen;
            default:
                return DependencyProperty.UnsetValue;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {
        throw new NotSupportedException();
    }
}

Usage:

<Window.Resources>
    <local:NameToBrushConverter x:Key="NameToBrushConverter"/>
</Window.Resources>
...
<DataGridTextColumn Binding="{Binding Name}">
    <DataGridTextColumn.ElementStyle>
        <Style TargetType="{x:Type TextBlock}">
            <Setter Property="Background" Value="{Binding Name, Converter={StaticResource NameToBrushConverter}}"/>
        </Style>
    </DataGridTextColumn.ElementStyle>
</DataGridTextColumn>

Yet another option is to directly bind the Background to a property which returns the respectively coloured brush. You will have to fire property change notifications in the setters of properties on which the colour is dependent.

e.g.

public string Name
{
    get { return _name; }
    set
    {
        if (_name != value)
        {
            _name = value;
            OnPropertyChanged(nameof(Name));
            OnPropertyChanged(nameof(NameBrush));
        }
    }
}

public Brush NameBrush
{
    get
    {
        switch (Name)
        {
            case "John":
                return Brushes.LightGreen;
            default:
                break;
        }

        return Brushes.Transparent;
    }
}

For arbitrary precision mathematics PHP offers the Binary Calculator which supports numbers of any size and precision, represented as strings.

$s = '1234.13';
$double = bcadd($s,'0',2);

PHP: bcadd

Try executing:

I use it in a worksheet in which control buttons change values of a dataset. On each click, Excel runs through this command and the graph updates immediately.

You could use pandas plot as @Bharath suggest:

import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)

Output:

Updated:

from matplotlib.colors import ListedColormap df.set_index('App')\ .reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\ .T.plot(kind='bar', stacked=True, colormap=ListedColormap(sns.color_palette("GnBu", 10)), figsize=(12,6))

Updated Pandas 0.21.0+ reindex_axis is deprecated, use reindex

from matplotlib.colors import ListedColormap

df.set_index('App')\
  .reindex(df.set_index('App').sum().sort_values().index, axis=1)\
  .T.plot(kind='bar', stacked=True,
          colormap=ListedColormap(sns.color_palette("GnBu", 10)), 
          figsize=(12,6))

Output:

At the package stage, the plugin allows configuration of the imported file names via file mapping:

maven-ear-plugin

http://maven.apache.org/plugins/maven-ear-plugin/examples/customize-file-name-mapping.html

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.7</version>
    <configuration>
       [...]
        <fileNameMapping>full</fileNameMapping>
    </configuration>
</plugin>

http://maven.apache.org/plugins/maven-war-plugin/war-mojo.html#outputFileNameMapping

If you have configured your version to be 'testing' via a profile or something, this would work for a war package:

maven-war-plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <encoding>UTF-8</encoding>                        
        <outputFileNameMapping>@{groupId}@-@{artifactId}@-@{baseVersion}@@{dashClassifier?}@.@{extension}@</outputFileNameMapping>
    </configuration>
</plugin>

steps :

1. run your xampp control panel
2. click the button saying config
3. select apache( httpd.conf )
4. find document root

replace

DocumentRoot "C:/xampp/htdocs"
<Directory "C:/xampp/htdocs">

Those 2 lines

| C:/xampp/htdocs == current location for root |

|change C:/xampp/htdocs with any location you want|

5. save it

I have just written a blog article that addresses exactly this, which you may find useful: http://seewah.blogspot.com/2009/10/circle-overlay-on-google-map.html

Basically, you need to create a GGroundOverlay with the correct GLatLngBounds. The tricky bit is in working out the southwest corner coordinate and the northeast corner coordinate of this imaginery square (the GLatLngBounds) bounding this circle, based on the desired radius. The math is quite complicated, but you can just refer to getDestLatLng function in the blog. The rest should be pretty straightforward.

No, it is not okay to put a link element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):

“This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.”

You can safely delete the WSDL cache files. If you wish to prevent future caching, use:

ini_set("soap.wsdl_cache_enabled", 0);

or dynamically:

$client = new SoapClient('http://somewhere.com/?wsdl', array('cache_wsdl' => WSDL_CACHE_NONE) );

This is the easiest way

exec sp_columns [tablename]

Check the answer of @Mahesh Kavathiya. For my case, in server code has only like this:

{
"notification": {
  "body": "here is body",
  "title": "Title",
 },
 "to": "sdfjsdfonsdofoiewj9230idsjkfmnkdsfm"
}

You need to change to:

{
 "data": {
  "body": "here is body",
  "title": "Title",
  "click_action": "YOUR_ACTION"
 },
"notification": {
  "body": "here is body",
  "title": "Title"
 },
 "to": "sdfjsdfonsdofoiewj9230idsjkfmnkdsfm"
}

Then, in case app in Background, the default activity intent extra will get "data"

Good luck!

It is not the most efficient in the world, but this should work:

get-content $file |
    select -Skip 1 |
    set-content "$file-temp"
move "$file-temp" $file -Force

Wordpress uses jQuery in noConflict mode by default. You need to reference it using jQuery as the variable name, not $, e.g. use

jQuery(document);

instead of

$(document);

You can easily wrap this up in a self executing function so that $ refers to jQuery again (and avoids polluting the global namespace as well), e.g.

(function ($) {
   $(document);
}(jQuery));

The correct value to check here is the SelectedItem property.

A ComboBox is a composite control with two of its parts being:

1. The Text Part: the value in the this part corresponds to the Text property of the ComboBox.
2. The Selector Part (i.e. the "drop-down" part): The selected item in this part corresponds to the SelectedItem property.

The image above was taken immediately after the ComboBox was expanded (i.e. before selecting a new value). At this point both Text and SelectedItem are "Info", assuming the ComboBox items were strings. If the ComboBox items were instead all the values of an Enum called "LogLevel", SelectedItem would currently be LogLevel.Info.

When an item in the drop-down is clicked on, the value of SelectedItem is changed and the SelectionChanged event is raised. The Text property isn't updated yet, though, as the Text Part isn't updated until after the SelectionChanged handler is finished. This can be observed by putting a breakpoint in the handler and looking at the control:

Since the Text Part hasn't been updated at this point, the Text property returns the previously selected value.

Use the onsubmit event to execute JavaScript code when the form is submitted. You can then return false or call the passed event's preventDefault method to disable the form submission.

For example:

<script>
function doSomething() {
    alert('Form submitted!');
    return false;
}
</script>

<form onsubmit="return doSomething();" class="my-form">
    <input type="submit" value="Submit">
</form>

This works, but it's best not to litter your HTML with JavaScript, just as you shouldn't write lots of inline CSS rules. Many Javascript frameworks facilitate this separation of concerns. In jQuery you bind an event using JavaScript code like so:

<script>
$('.my-form').on('submit', function () {
    alert('Form submitted!');
    return false;
});
</script>

<form class="my-form">
    <input type="submit" value="Submit">
</form>

I've posted a step-by-step procedure for creating a Windows service in C# here. It sounds like you're at least to this point, and now you're wondering how to start the service once it is installed. Setting the StartType property to Automatic will cause the service to start automatically after rebooting your system, but it will not (as you've discovered) automatically start your service after installation.

I don't remember where I found it originally (perhaps Marc Gravell?), but I did find a solution online that allows you to install and start your service by actually running your service itself. Here's the step-by-step:

1. Structure the Main() function of your service like this:

   static void Main(string[] args)
   {
       if (args.Length == 0) {
           // Run your service normally.
           ServiceBase[] ServicesToRun = new ServiceBase[] {new YourService()};
           ServiceBase.Run(ServicesToRun);
       } else if (args.Length == 1) {
           switch (args[0]) {
               case "-install":
                   InstallService();
                   StartService();
                   break;
               case "-uninstall":
                   StopService();
                   UninstallService();
                   break;
               default:
                   throw new NotImplementedException();
           }
       }
   }
   

2. Here is the supporting code:

   using System.Collections;
   using System.Configuration.Install;
   using System.ServiceProcess;
   
   private static bool IsInstalled()
   {
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               ServiceControllerStatus status = controller.Status;
           } catch {
               return false;
           }
           return true;
       }
   }
   
   private static bool IsRunning()
   {
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           if (!IsInstalled()) return false;
           return (controller.Status == ServiceControllerStatus.Running);
       }
   }
   
   private static AssemblyInstaller GetInstaller()
   {
       AssemblyInstaller installer = new AssemblyInstaller(
           typeof(YourServiceType).Assembly, null);
       installer.UseNewContext = true;
       return installer;
   }
   

3. Continuing with the supporting code...

   private static void InstallService()
   {
       if (IsInstalled()) return;
   
       try {
           using (AssemblyInstaller installer = GetInstaller()) {
               IDictionary state = new Hashtable();
               try {
                   installer.Install(state);
                   installer.Commit(state);
               } catch {
                   try {
                       installer.Rollback(state);
                   } catch { }
                   throw;
               }
           }
       } catch {
           throw;
       }
   }
   
   private static void UninstallService()
   {
       if ( !IsInstalled() ) return;
       try {
           using ( AssemblyInstaller installer = GetInstaller() ) {
               IDictionary state = new Hashtable();
               try {
                   installer.Uninstall( state );
               } catch {
                   throw;
               }
           }
       } catch {
           throw;
       }
   }
   
   private static void StartService()
   {
       if ( !IsInstalled() ) return;
   
       using (ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               if ( controller.Status != ServiceControllerStatus.Running ) {
                   controller.Start();
                   controller.WaitForStatus( ServiceControllerStatus.Running, 
                       TimeSpan.FromSeconds( 10 ) );
               }
           } catch {
               throw;
           }
       }
   }
   
   private static void StopService()
   {
       if ( !IsInstalled() ) return;
       using ( ServiceController controller = 
           new ServiceController("YourServiceName")) {
           try {
               if ( controller.Status != ServiceControllerStatus.Stopped ) {
                   controller.Stop();
                   controller.WaitForStatus( ServiceControllerStatus.Stopped, 
                        TimeSpan.FromSeconds( 10 ) );
               }
           } catch {
               throw;
           }
       }
   }
   

4. At this point, after you install your service on the target machine, just run your service from the command line (like any ordinary application) with the -install command line argument to install and start your service.

I think I've covered everything, but if you find this doesn't work, please let me know so I can update the answer.

in some case you can use annotation @Primary.

@Primary
class USA implements Country {}

This way it will be selected as the default autowire candididate, with no need to autowire-candidate on the other bean.

for mo deatils look at Autowiring two beans implementing same interface - how to set default bean to autowire?

This question is very much answered by other people, I just want to make a point whenever deciding on any service to be in AWS is that understanding the use case for each and also see the solution that the service will provide in terms of the Well-Architected Framework, do you need High Availability, Fault Torelant, Cost optimization. This will help to decide on any kind of service to be used.

Edit!: Please be sure that you should have both Python installed on your computer.

Maybe my answer is late for you but I can help someone who has the same problem!

You don't have to download both Anaconda.

If you are using Spyder and Jupyter in Anaconda environmen and,

If you have already Anaconda 2 type in Terminal:

    python3 -m pip install ipykernel

    python3 -m ipykernel install --user

If you have already Anaconda 3 then type in terminal:

    python2 -m pip install ipykernel

    python2 -m ipykernel install --user

Then before use Spyder you can choose Python environment like below! Sometimes only you can see root and your new Python environment, so root is your first anaconda environment!

Also this is Jupyter. You can choose python version like this!

I hope it will help.

In most browsers, you can use a javascript variable instead of using document.getElementById. Say your html body content is like this:

<section id="mySection"> Hello </section>

Then you can just refer to mySection as a variable in javascript:

mySection.innerText += ', world'
// same as: document.getElementById('mySection').innerText += ', world'

See this snippet:

mySection.innerText += ', world!'

<section id="mySection"> Hello </section>

In case it helps someone, if your variables have hyphens in them, you may see this error since hyphens are not allowed in variable names in Python and are used as subtraction operators.

Example:

my-variable = 5   # would result in 'SyntaxError: can't assign to operator'

It appears that the :include functionality was changed with Rails 2.1. Rails used to do the join in all cases, but for performance reasons it was changed to use multiple queries in some circumstances. This blog post by Fabio Akita has some good information on the change (see the section entitled "Optimized Eager Loading").

I had a similar error on my side when I was using JDBC in Java code.

According to this website (the second awnser) it suggest that you are trying to execute the query with a missing parameter.

For instance :

exec SomeStoredProcedureThatReturnsASite( :L_kSite );

You are trying to execute the query without the last parameter.

Maybe in SQLPlus it doesn't have the same requirements, so it might have been a luck that it worked there.

I wrote this a while ago to remind myself of what a closure is and how it works in JS.

A closure is a function that, when called, uses the scope in which it was declared, not the scope in which it was called. In javaScript, all functions behave like this. Variable values in a scope persist as long as there is a function that still points to them. The exception to the rule is 'this', which refers to the object that the function is inside when it is called.

var z = 1;
function x(){
    var z = 2; 
    y(function(){
      alert(z);
    });
}
function y(f){
    var z = 3;
    f();
}
x(); //alerts '2' 

Well, here's an example for overloaded constructors.

public class Employee
{
   private String name;
   private int age;

   public Employee()
   {
      System.out.println("We are inside Employee() constructor");
   }

   public Employee(String name)
   {
      System.out.println("We are inside Employee(String name) constructor");
      this.name = name;
   }

   public Employee(String name, int age)
   {
      System.out.println("We are inside Employee(String name, int age) constructor");
      this.name = name;
      this.age = age;
   }

   public Employee(int age)
   {
      System.out.println("We are inside Employee(int age) constructor");
      this.age = age; 
   }

   public String getName()
   {
      return name;
   }

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

   public int getAge()
   {
      return age;
   }

   public void setAge(int age)
   {
      this.age = age;
   }
}

In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.

Here are some resources which throw more light on constructor overloading in java,

Constructors.

Constructor explanation.

Taking DWins example.

What I often do, particularly when I use many, many different plots with the same colours or size information, is I store them in variables I otherwise never use. This helps me keep my code a little cleaner AND I can change it "globally".

E.g.

clab = 1.5
cmain = 2
caxis = 1.2

plot(1, 1 ,xlab="x axis", ylab="y axis",  pch=19,
           col.lab="red", cex.lab=clab,    
           col="green", main = "Testing scatterplots", cex.main =cmain, cex.axis=caxis) 

You can also write a function, doing something similar. But for a quick shot this is ideal. You can also store that kind of information in an extra script, so you don't have a messy plot script:

which you then call with setwd("") source("plotcolours.r")

in a file say called plotcolours.r you then store all the e.g. colour or size variables

clab = 1.5
cmain = 2
caxis = 1.2 

for colours could use

darkred<-rgb(113,28,47,maxColorValue=255)

as your variable 'darkred' now has the colour information stored, you can access it in your actual plotting script.

plot(1,1,col=darkred) 

To get a scrollbar for an ItemsControl, you can host it in a ScrollViewer like this:

<ScrollViewer VerticalScrollBarVisibility="Auto">
  <ItemsControl>
    <uc:UcSpeler />
    <uc:UcSpeler />
    <uc:UcSpeler />
    <uc:UcSpeler />
    <uc:UcSpeler />
  </ItemsControl>
</ScrollViewer>

I create the tag like this and then I push it to GitHub:

git tag -a v1.1 -m "Version 1.1 is waiting for review"
git push --tags

Here are three simple implementations, first the oneliner:

public static boolean oneLinerPalin(String str){
    return str.equals(new StringBuffer(str).reverse().toString());
}

This is ofcourse quite slow since it creates a stringbuffer and reverses it, and the whole string is always checked nomatter if it is a palindrome or not, so here is an implementation that only checks the required amount of chars and does it in place, so no extra stringBuffers:

public static boolean isPalindrome(String str){

    if(str.isEmpty()) return true;

    int last = str.length() - 1;        

    for(int i = 0; i <= last / 2;i++)
        if(str.charAt(i) != str.charAt(last - i))
            return false;

    return true;
}

And recursively:

public static boolean recursivePalin(String str){
    return check(str, 0, str.length() - 1);
}

private static boolean check (String str,int start,int stop){
    return stop - start < 2 ||
           str.charAt(start) == str.charAt(stop) &&
           check(str, start + 1, stop - 1);
}

Detecting a loop in a linked list can be done in one of the simplest ways, which results in O(N) complexity using hashmap or O(NlogN) using a sort based approach.

As you traverse the list starting from head, create a sorted list of addresses. When you insert a new address, check if the address is already there in the sorted list, which takes O(logN) complexity.

Underlying cause:
Content scripts are executed in an "isolated world" environment.

Solution::
To access functions/variables of the page context ("main world") you have to inject the code into the page itself using DOM. Same thing if you want to expose your functions/variables to the page context (in your case it's the state() method).

• Note in case communication with the page script is needed:
  Use DOM CustomEvent handler. Examples: one, two, and three.

• Note in case chrome API is needed in the page script:
  Since chrome.* APIs can't be used in the page script, you have to use them in the content script and send the results to the page script via DOM messaging (see the note above).

Safety warning:
A page may redefine or augment/hook a built-in prototype so your exposed code may fail if the page did it in an incompatible fashion. If you want to make sure your exposed code runs in a safe environment then you should either a) declare your content script with "run_at": "document_start" and use Methods 2-3 not 1, or b) extract the original native built-ins via an empty iframe, example. Note that with document_start you may need to use DOMContentLoaded event inside the exposed code to wait for DOM.

Table of contents

• Method 1: Inject another file
• Method 2: Inject embedded code
• Method 2b: Using a function
• Method 3: Using an inline event
• Dynamic values in the injected code

Method 1: Inject another file

This is the easiest/best method when you have lots of code. Include your actual JS code in a file within your extension, say script.js. Then let your content script be as follows (explained here: Google Chome “Application Shortcut” Custom Javascript):

var s = document.createElement('script');
// TODO: add "script.js" to web_accessible_resources in manifest.json
s.src = chrome.runtime.getURL('script.js');
s.onload = function() {
    this.remove();
};
(document.head || document.documentElement).appendChild(s);

Note: For security reasons, Chrome prevents loading of js files. Your file must be added as a "web_accessible_resources" item (example) :

// manifest.json must include: 
"web_accessible_resources": ["script.js"],

If not, the following error will appear in the console:

Denying load of chrome-extension://[EXTENSIONID]/script.js. Resources must be listed in the web_accessible_resources manifest key in order to be loaded by pages outside the extension.

Method 2: Inject embedded code

This method is useful when you want to quickly run a small piece of code. (See also: How to disable facebook hotkeys with Chrome extension?).

var actualCode = `// Code here.
// If you want to use a variable, use $ and curly braces.
// For example, to use a fixed random number:
var someFixedRandomValue = ${ Math.random() };
// NOTE: Do not insert unsafe variables in this way, see below
// at "Dynamic values in the injected code"
`;

var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();

Note: template literals are only supported in Chrome 41 and above. If you want the extension to work in Chrome 40-, use:

var actualCode = ['/* Code here. Example: */' + 'alert(0);',
                  '// Beware! This array have to be joined',
                  '// using a newline. Otherwise, missing semicolons',
                  '// or single-line comments (//) will mess up your',
                  '// code ----->'].join('\n');

Method 2b: Using a function

For a big chunk of code, quoting the string is not feasible. Instead of using an array, a function can be used, and stringified:

var actualCode = '(' + function() {
    // All code is executed in a local scope.
    // For example, the following does NOT overwrite the global `alert` method
    var alert = null;
    // To overwrite a global variable, prefix `window`:
    window.alert = null;
} + ')();';
var script = document.createElement('script');
script.textContent = actualCode;
(document.head||document.documentElement).appendChild(script);
script.remove();

This method works, because the + operator on strings and a function converts all objects to a string. If you intend on using the code more than once, it's wise to create a function to avoid code repetition. An implementation might look like:

function injectScript(func) {
    var actualCode = '(' + func + ')();'
    ...
}
injectScript(function() {
   alert("Injected script");
});

Note: Since the function is serialized, the original scope, and all bound properties are lost!

var scriptToInject = function() {
    console.log(typeof scriptToInject);
};
injectScript(scriptToInject);
// Console output:  "undefined"

Method 3: Using an inline event

Sometimes, you want to run some code immediately, e.g. to run some code before the <head> element is created. This can be done by inserting a <script> tag with textContent (see method 2/2b).

An alternative, but not recommended is to use inline events. It is not recommended because if the page defines a Content Security policy that forbids inline scripts, then inline event listeners are blocked. Inline scripts injected by the extension, on the other hand, still run. If you still want to use inline events, this is how:

var actualCode = '// Some code example \n' + 
                 'console.log(document.documentElement.outerHTML);';

document.documentElement.setAttribute('onreset', actualCode);
document.documentElement.dispatchEvent(new CustomEvent('reset'));
document.documentElement.removeAttribute('onreset');

Note: This method assumes that there are no other global event listeners that handle the reset event. If there is, you can also pick one of the other global events. Just open the JavaScript console (F12), type document.documentElement.on, and pick on of the available events.

Dynamic values in the injected code

Occasionally, you need to pass an arbitrary variable to the injected function. For example:

var GREETING = "Hi, I'm ";
var NAME = "Rob";
var scriptToInject = function() {
    alert(GREETING + NAME);
};

To inject this code, you need to pass the variables as arguments to the anonymous function. Be sure to implement it correctly! The following will not work:

var scriptToInject = function (GREETING, NAME) { ... };
var actualCode = '(' + scriptToInject + ')(' + GREETING + ',' + NAME + ')';
// The previous will work for numbers and booleans, but not strings.
// To see why, have a look at the resulting string:
var actualCode = "(function(GREETING, NAME) {...})(Hi, I'm ,Rob)";
//                                                 ^^^^^^^^ ^^^ No string literals!

The solution is to use JSON.stringify before passing the argument. Example:

var actualCode = '(' + function(greeting, name) { ...
} + ')(' + JSON.stringify(GREETING) + ',' + JSON.stringify(NAME) + ')';

If you have many variables, it's worthwhile to use JSON.stringify once, to improve readability, as follows:

...
} + ')(' + JSON.stringify([arg1, arg2, arg3, arg4]) + ')';

Multiple pdf merged method using org.apache.pdfbox:

public void mergePDFFiles(List<File> files,
                          String mergedFileName) {
    try {
        PDFMergerUtility pdfmerger = new PDFMergerUtility();
        for (File file : files) {
            PDDocument document = PDDocument.load(file);
            pdfmerger.setDestinationFileName(mergedFileName);
            pdfmerger.addSource(file);
            pdfmerger.mergeDocuments(MemoryUsageSetting.setupTempFileOnly());
            document.close();
        }
    } catch (IOException e) {
        logger.error("Error to merge files. Error: " + e.getMessage());
    }
}

From main program, call mergePDFFiles method using list of files and target file name.

        String mergedFileName = "Merged.pdf";
        mergePDFFiles(files, mergedFileName);

After calling mergePDFFiles, load merged file

        File mergedFile = new File(mergedFileName);

First, keep in mind that, in its precise definition, a module is an object in the memory of a Python interpreter, often created by reading one or more files from disk. While we may informally call a disk file such as a/b/c.py a "module," it doesn't actually become one until it's combined with information from several other sources (such as sys.path) to create the module object.

(Note, for example, that two modules with different names can be loaded from the same file, depending on sys.path and other settings. This is exactly what happens with python -m my.module followed by an import my.module in the interpreter; there will be two module objects, __main__ and my.module, both created from the same file on disk, my/module.py.)

A package is a module that may have submodules (including subpackages). Not all modules can do this. As an example, create a small module hierarchy:

$ mkdir -p a/b
$ touch a/b/c.py

Ensure that there are no other files under a. Start a Python 3.4 or later interpreter (e.g., with python3 -i) and examine the results of the following statements:

import a
a                ? <module 'a' (namespace)>
a.b              ? AttributeError: module 'a' has no attribute 'b'
import a.b.c
a.b              ? <module 'a.b' (namespace)>
a.b.c            ? <module 'a.b.c' from '/home/cjs/a/b/c.py'>

Modules a and a.b are packages (in fact, a certain kind of package called a "namespace package," though we wont' worry about that here). However, module a.b.c is not a package. We can demonstrate this by adding another file, a/b.py to the directory structure above and starting a fresh interpreter:

import a.b.c
? ImportError: No module named 'a.b.c'; 'a.b' is not a package
import a.b
a                ? <module 'a' (namespace)>
a.__path__       ? _NamespacePath(['/.../a'])
a.b              ? <module 'a.b' from '/home/cjs/tmp/a/b.py'>
a.b.__path__     ? AttributeError: 'module' object has no attribute '__path__'

Python ensures that all parent modules are loaded before a child module is loaded. Above it finds that a/ is a directory, and so creates a namespace package a, and that a/b.py is a Python source file which it loads and uses to create a (non-package) module a.b. At this point you cannot have a module a.b.c because a.b is not a package, and thus cannot have submodules.

You can also see here that the package module a has a __path__ attribute (packages must have this) but the non-package module a.b does not.

You can adjust the subplot geometry in the very tight_layout call as follows:

fig.tight_layout(rect=[0, 0.03, 1, 0.95])

As it's stated in the documentation (https://matplotlib.org/users/tight_layout_guide.html):

tight_layout() only considers ticklabels, axis labels, and titles. Thus, other artists may be clipped and also may overlap.

This error message can also be caused when upgrading Xcode (and subsequently to a new version of Swift) and your project uses a framework built/compiled with an older/previous version of Swift.

In this case rebuilding the framework and re-adding it will fix the problem.

You can use recode from the car package:

library(ggplot2) #get data
library(car)
daimons$new_var <- recode(diamonds$clarity , "'I1' = 'low';'SI2' = 'low';else = 'high';")[1:10]

Editing file /etc/apt/sources.list.d/additional-repositories.list and adding deb [arch=amd64] https://download.docker.com/linux/ubuntu xenial stable worked for me, this post was very helpful https://github.com/typora/typora-issues/issues/2065

• There is no runtime impact, as compiler automatically replaces the * with concrete class names. If you decompile the .class file, you would never see import ...*.

• C# always uses * (implicitly) as you can only using package name. You can never specify the class name at all. Java introduces the feature after c#. (Java is so tricky in many aspects but it's beyond this topic).

• In Intellij Idea when you do "organize imports", it automatically replaces multiple imports of the same package with *. This is a mandantory feature as you can not turn it off (though you can increase the threshold).

• The case listed by the accepted reply is not valid. Without * you still got the same issue. You need specify the pakcage name in your code no matter you use * or not.

Its BECAUSE there is no font family with name @"System" hence size:36 will also not work ...

Check the fonts available in xcode in attribute inspector and try

EDIT:

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).

A quick rerun of your data:

In [25]: df.hist(column='Trip_distance')

Prints out absolutely fine.

The df.hist function comes with an optional keyword argument bins=10 which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:

In [34]: df.hist(column='Trip_distance', bins=50)

Exit [construct], and intelisense will tell you which one(s) are valid in a particular place.

Try a case statement

WHERE
CASE WHEN @zipCode IS NULL THEN 1
ELSE @zipCode
END

Working with GPX files with Xcode compatibility

I followed the link given by AlexWien and it was extremely useful: https://blackpixel.com/writing/2013/05/simulating-locations-with-xcode.html

But, I spent quite some time searching for how to generate .gpx files with waypoints (wpt tags), as Xcode only accepts wpt tags.

The following tool converts a Google Maps link (also works with Google Maps Directions) to a .gpx file.

https://mapstogpx.com/mobiledev.php

Simulating a trip duration is supported, custom durations can be specified. Just select Xcode and it gets the route as waypoints.

All of the DISPATCH_QUEUE_PRIORITY_X queues are concurrent queues (meaning they can execute multiple tasks at once), and are FIFO in the sense that tasks within a given queue will begin executing using "first in, first out" order. This is in comparison to the main queue (from dispatch_get_main_queue()), which is a serial queue (tasks will begin executing and finish executing in the order in which they are received).

So, if you send 1000 dispatch_async() blocks to DISPATCH_QUEUE_PRIORITY_DEFAULT, those tasks will start executing in the order you sent them into the queue. Likewise for the HIGH, LOW, and BACKGROUND queues. Anything you send into any of these queues is executed in the background on alternate threads, away from your main application thread. Therefore, these queues are suitable for executing tasks such as background downloading, compression, computation, etc.

Note that the order of execution is FIFO on a per-queue basis. So if you send 1000 dispatch_async() tasks to the four different concurrent queues, evenly splitting them and sending them to BACKGROUND, LOW, DEFAULT and HIGH in order (ie you schedule the last 250 tasks on the HIGH queue), it's very likely that the first tasks you see starting will be on that HIGH queue as the system has taken your implication that those tasks need to get to the CPU as quickly as possible.

Note also that I say "will begin executing in order", but keep in mind that as concurrent queues things won't necessarily FINISH executing in order depending on length of time for each task.

As per Apple:

https://developer.apple.com/library/content/documentation/General/Conceptual/ConcurrencyProgrammingGuide/OperationQueues/OperationQueues.html

A concurrent dispatch queue is useful when you have multiple tasks that can run in parallel. A concurrent queue is still a queue in that it dequeues tasks in a first-in, first-out order; however, a concurrent queue may dequeue additional tasks before any previous tasks finish. The actual number of tasks executed by a concurrent queue at any given moment is variable and can change dynamically as conditions in your application change. Many factors affect the number of tasks executed by the concurrent queues, including the number of available cores, the amount of work being done by other processes, and the number and priority of tasks in other serial dispatch queues.

Basically, if you send those 1000 dispatch_async() blocks to a DEFAULT, HIGH, LOW, or BACKGROUND queue they will all start executing in the order you send them. However, shorter tasks may finish before longer ones. Reasons behind this are if there are available CPU cores or if the current queue tasks are performing computationally non-intensive work (thus making the system think it can dispatch additional tasks in parallel regardless of core count).

The level of concurrency is handled entirely by the system and is based on system load and other internally determined factors. This is the beauty of Grand Central Dispatch (the dispatch_async() system) - you just make your work units as code blocks, set a priority for them (based on the queue you choose) and let the system handle the rest.

So to answer your above question: you are partially correct. You are "asking that code" to perform concurrent tasks on a global concurrent queue at the specified priority level. The code in the block will execute in the background and any additional (similar) code will execute potentially in parallel depending on the system's assessment of available resources.

The "main" queue on the other hand (from dispatch_get_main_queue()) is a serial queue (not concurrent). Tasks sent to the main queue will always execute in order and will always finish in order. These tasks will also be executed on the UI Thread so it's suitable for updating your UI with progress messages, completion notifications, etc.

Another way is using 'HttpClient' like this:

using System;
using System.Net;
using System.Net.Http;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Making API Call...");
            using (var client = new HttpClient(new HttpClientHandler { AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate }))
            {
                client.BaseAddress = new Uri("https://api.stackexchange.com/2.2/");
                HttpResponseMessage response = client.GetAsync("answers?order=desc&sort=activity&site=stackoverflow").Result;
                response.EnsureSuccessStatusCode();
                string result = response.Content.ReadAsStringAsync().Result;
                Console.WriteLine("Result: " + result);
            }
            Console.ReadLine();
        }
    }
}

Check HttpClient vs HttpWebRequest from stackoverflow and this from other.

Update June 22, 2020: It's not recommended to use httpclient in a 'using' block as it might cause port exhaustion.

private static HttpClient client = null;
    
ContructorMethod()
{
   if(client == null)
   {
        HttpClientHandler handler = new HttpClientHandler()
        {
            AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
        };        
        client = new HttpClient(handler);
   }
   client.BaseAddress = new Uri("https://api.stackexchange.com/2.2/");
   HttpResponseMessage response = client.GetAsync("answers?order=desc&sort=activity&site=stackoverflow").Result;
   response.EnsureSuccessStatusCode();
   string result = response.Content.ReadAsStringAsync().Result;
            Console.WriteLine("Result: " + result);           
 }

If using .Net Core 2.1+, consider using IHttpClientFactory and injecting like this in your startup code.

 var timeout = Policy.TimeoutAsync<HttpResponseMessage>(
            TimeSpan.FromSeconds(60));

 services.AddHttpClient<XApiClient>().ConfigurePrimaryHttpMessageHandler(() => new HttpClientHandler
        {
            AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate
        }).AddPolicyHandler(request => timeout);

i suggest using this ...

np.arange(start_index, end_index, intervals)[::-1]

for example:

np.arange(10, 20, 0.5)
np.arange(10, 20, 0.5)[::-1]

Then your resault:

[ 19.5,  19. ,  18.5,  18. ,  17.5,  17. ,  16.5,  16. ,  15.5,
    15. ,  14.5,  14. ,  13.5,  13. ,  12.5,  12. ,  11.5,  11. ,
    10.5,  10. ]

On the properties tab of the report (myReport.rdlc), change the "Keep Together" attribute to False. I've been struggling with this issue for a while and this seems to have solved my issue.

The return value for main indicates how the program exited. Normal exit is represented by a 0 return value from main. Abnormal exit is signaled by a non-zero return, but there is no standard for how non-zero codes are interpreted. As noted by others, void main() is prohibited by the C++ standard and should not be used. The valid C++ main signatures are:

int main()

and

int main(int argc, char* argv[])

which is equivalent to

int main(int argc, char** argv)

It is also worth noting that in C++, int main() can be left without a return-statement, at which point it defaults to returning 0. This is also true with a C99 program. Whether return 0; should be omitted or not is open to debate. The range of valid C program main signatures is much greater.

Efficiency is not an issue with the main function. It can only be entered and left once (marking the program's start and termination) according to the C++ standard. For C, re-entering main() is allowed, but should be avoided.

Try this query:

SELECT sysdate FROM schema_name.table_name;

This should display the timestamp that you might need.

when I create my JLabel and enter the text to it, there is no wordwrap or anything

HTML formatting can be used to cause word wrap in any Swing component that offers styled text. E.G. as demonstrated in this answer.

SET

SET @var_name = value 

OR

SET @var := value

both operators = and := are accepted

SELECT

SELECT col1, @var_name := col2 from tb_name WHERE "conditon";

if multiple record sets found only the last value in col2 is keep (override);

SELECT col1, col2 INTO @var_name, col3 FROM .....

in this case the result of select is not containing col2 values

Ex both methods used

-- TRIGGER_BEFORE_INSERT --- setting a column value from calculations

...
SELECT count(*) INTO @NR FROM a_table WHERE a_condition;
SET NEW.ord_col =  IFNULL( @NR, 0 ) + 1;
...

In this part of your SP:

IF @DateFirst <> '' and @DateLast <> ''
   set @FinalSQL  = @FinalSQL
       + '  or convert (Date,DateLog) >=     ''' + @DateFirst
       + ' and convert (Date,DateLog) <=''' + @DateLast  

you are trying to concatenate strings and datetimes.

As the datetime type has higher priority than varchar/nvarchar, the + operator, when it happens between a string and a datetime, is interpreted as addition, not as concatenation, and the engine then tries to convert your string parts (' or convert (Date,DateLog) >= ''' and others) to datetime or numeric values. And fails.

That doesn't happen if you omit the last two parameters when invoking the procedure, because the condition evaluates to false and the offending statement isn't executed.

To amend the situation, you need to add explicit casting of your datetime variables to strings:

set @FinalSQL  = @FinalSQL
    + '  or convert (Date,DateLog) >=     ''' + convert(date, @DateFirst)
    + ' and convert (Date,DateLog) <=''' + convert(date, @DateLast)

You'll also need to add closing single quotes:

set @FinalSQL  = @FinalSQL
    + '  or convert (Date,DateLog) >=     ''' + convert(date, @DateFirst) + ''''
    + ' and convert (Date,DateLog) <=''' + convert(date, @DateLast) + ''''

In a microservice infrastructure (does not fit the problem, I know ;)) you must not use:

server:
  ssl:
    trust-store: path-to-truststore...
    trust-store-password: my-secret-password...

Instead the ribbon loadbalancer can be configuered:

ribbon: 
  TrustStore: keystore.jks
  TrustStorePassword : example
  ReadTimeout: 60000
  IsSecure: true
  MaxAutoRetries: 1

Here https://github.com/rajaramkushwaha/https-zuul-proxy-spring-boot-app you can find a working sample. There was also a github discussion about that, but I didn't find it anymore.

A lot of the other solutions that use keypress will not work on mobile, you need to use input.

html

<input type="text" id="name"  data-value="" autocomplete="off" spellcheck="true" placeholder="Type your name" autofocus />

jQuery

$('#name').on('input', function() {
    var cursor_pos = $(this).getCursorPosition()
    if(!(/^[a-zA-Z ']*$/.test($(this).val())) ) {
        $(this).val($(this).attr('data-value'))
        $(this).setCursorPosition(cursor_pos - 1)
        return
    }
    $(this).attr('data-value', $(this).val())
})

$.fn.getCursorPosition = function() {
    if(this.length == 0) return -1
    return $(this).getSelectionStart()
}
$.fn.setCursorPosition = function(position) {
    if(this.lengh == 0) return this
    return $(this).setSelection(position, position)
}
$.fn.getSelectionStart = function(){
  if(this.lengh == 0) return -1
  input = this[0]
  var pos = input.value.length
  if (input.createTextRange) {
    var r = document.selection.createRange().duplicate()
    r.moveEnd('character', input.value.length)
    if (r.text == '') 
    pos = input.value.length
    pos = input.value.lastIndexOf(r.text)
  } else if(typeof(input.selectionStart)!="undefined")
  pos = input.selectionStart
  return pos
}
$.fn.setSelection = function(selectionStart, selectionEnd) {
  if(this.lengh == 0) return this
  input = this[0]
  if(input.createTextRange) {
    var range = input.createTextRange()
    range.collapse(true)
    range.moveEnd('character', selectionEnd)
    range.moveStart('character', selectionStart)
    range.select()
  }
  else if (input.setSelectionRange) {
    input.focus()
    input.setSelectionRange(selectionStart, selectionEnd)
  }
  return this
}

This will work for IPv4 and IPv6:

^(([0-9a-f]{0,4}:){1,7}[0-9a-f]{1,4}|([0-9]{1,3}\.){3}[0-9]{1,3})$

For Mac - Holding option key followed by ctrl V while selecting the text did the trick.

EDIT : this answer is old. Usage of MD5 is now discouraged as it can easily be broken.

MD5 must be good enough for you I imagine? You can achieve it with MessageDigest.

MessageDigest.getInstance("MD5");

There are also other algorithms listed here.

And here's an third party version of it, if you really want: Fast MD5

If your Windows 7 machine is a member of an AD, or if you have UAC enabled, or if security policies are in effect, telnet more often than not must be run as an admin. The easiest way to do this is as follows

1. Create a shortcut that calls cmd.exe

2. Go to the shortcut's properties

3. Click on the Advanced button

4. Check the "Run as an administrator" checkbox

   After these steps you're all set and telnet should work now.

You have to use the contents() method:

$("#myiframe").contents().find("#myContent")

if you want to apply separate css classes for same element with conditions in Vue.js you can use the below given method.it worked in my scenario.

html

 <div class="Main" v-bind:class="{ Sub: page}"  >

in here, Main and Sub are two different class names for same div element. v-bind:class directive is used to bind the sub class in here. page is the property we use to update the classes when it's value changed.

js

data:{
page : true;
}

here we can apply a condition if we needed. so, if the page property becomes true element will go with Main and Sub claases css styles. but if false only Main class css styles will be applied.

If you lost a keystore file, don't create/update the new one with another set of value. First do the thorough search. Because it will overwrite the old one, so it will not match to your previous apk.

If you use eclipse most probably it will store in default path. For MAC (eclipse) it will be in your elispse installation path something like:

/Applications/eclipse/Eclipse.app/Contents/MacOS/

then your keystore file without any extension. You need root privilege to access this path (file).

Do not use Bitmap.Config.ARGB_8888

Instead use int w = WIDTH_PX, h = HEIGHT_PX;

Bitmap.Config conf = Bitmap.Config.ARGB_4444; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);

// ready to draw on that bitmap through that canvas

ARGB_8888 can land you in OutOfMemory issues when dealing with more bitmaps or large bitmaps. Or better yet, try avoiding usage of ARGB option itself.

For anyone looking for a full solution, I got this working with the following code based on maximdim's answer:

import javax.mail.*
import javax.mail.internet.*

private class SMTPAuthenticator extends Authenticator
{
    public PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication('[email protected]', 'test1234');
    }
}

def  d_email = "[email protected]",
        d_uname = "email",
        d_password = "password",
        d_host = "smtp.gmail.com",
        d_port  = "465", //465,587
        m_to = "[email protected]",
        m_subject = "Testing",
        m_text = "Hey, this is the testing email."

def props = new Properties()
props.put("mail.smtp.user", d_email)
props.put("mail.smtp.host", d_host)
props.put("mail.smtp.port", d_port)
props.put("mail.smtp.starttls.enable","true")
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true")
props.put("mail.smtp.socketFactory.port", d_port)
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
props.put("mail.smtp.socketFactory.fallback", "false")

def auth = new SMTPAuthenticator()
def session = Session.getInstance(props, auth)
session.setDebug(true);

def msg = new MimeMessage(session)
msg.setText(m_text)
msg.setSubject(m_subject)
msg.setFrom(new InternetAddress(d_email))
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to))

Transport transport = session.getTransport("smtps");
transport.connect(d_host, 465, d_uname, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

public static void convertStringToDecimal(String binary)
{
    int decimal=0;
    int power=0;
    while(binary.length()>0)
    {
        int temp = Integer.parseInt(binary.charAt((binary.length())-1)+"");
        decimal+=temp*Math.pow(2, power++);
        binary=binary.substring(0,binary.length()-1);
    }
    System.out.println(decimal);
}

Easiest way I think is:

var s = yourString.replace(/.*_/g,"_");

I had same issue . I passed my data as key->value in "Body" section by choosing "form-data" option and it worked fine.

Toggle checkbox checked

$("#checkall").click(function(){
    $("input:checkbox").prop( 'checked',$(this).is(":checked") );
})

As a general rule, modifying schema based on something that a user could change (such as adding a question to a survey) should be considered fairly smelly. There's cases where it can be appropriate, particularly when dealing with large amounts of data, but know what you're getting into before you dive in. Having just a "responses" table for each survey means that adding or removing questions is potentially very costly, and it's very difficult to do analytics in a question-agnostic way.

I think your second approach is best, but if you're certain you're going to have a lot of scale concerns, one thing that has worked for me in the past is a hybrid approach:

1. Create detailed response tables to store per-question responses as you've described in 2. This data would generally not be directly queried from your application, but would be used for generating summary data for reporting tables. You'd probably also want to implement some form of archiving or expunging for this data.
2. Also create the responses table from 1 if necessary. This can be used whenever users want to see a simple table for results.
3. For any analytics that need to be done for reporting purposes, schedule jobs to create additional summary data based on the data from 1.

This is absolutely a lot more work to implement, so I really wouldn't advise this unless you know for certain that this table is going to run into massive scale concerns.

In 2013, with all the HTML5 stuff, you can just omit the 'action' attribute to self-submit a form

<form>

Actually, the Form Submission subsection of the current HTML5 draft does not allow action="" (empty attribute). It is against the specification.

From this other Stack Overflow answer.

A little late to the game here, but another option is:

public class NerdDinners : DbContext
{
    public NerdDinners(string connString)
    {
        this.Database.Connection.ConnectionString = connString;
    }
    public DbSet<Dinner> Dinners { get; set; }
}

The Rectangle method

The simplest and most reliable way I've found of achieving worksheets/page-breaks is with use of the rectangle tool.

Group your page within rectangles or a single rectangle that fills the page in a sub-report, as follows:

• The quickest way I've found of placing the rectangle is to draw it around the objects you wish to place in the rectangle.

• Right click and in the layout menu, send the rectangle to back.

• Select all your objects and drag them slightly, but be sure they land in the same place they were. They will all now be in the rectangle.

In the rectangle properties you can set the page-break to occur at the start or end of the rectangle and name of the page can be based on an expression.

The worksheets will be named the same as the name of the page.

Duplicate names will have a number in brackets suffix.

Note: Ensure that the names are valid worksheet names.

A thread on MSDN Social, Re: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server, has a pretty decent list of possible issues that are related to your error. You may want to see if any of them could be what you're experiencing.

• Incorrect connection string, such as using SqlExpress
• Named Pipes(NP) was not enabled on the SQL instance
• Remote connection was not enabled
• Server not started, or point to not a real server in your connection string
• Other reasons such as incorrect security context
• try basic connectivity tests between the two machines you are working on

Have you tried copying the schema file to the XML Schema Caching folder for VS? You can find the location of that folder by looking at VS Tools/Options/Test Editor/XML/Miscellaneous. Unfortunately, i don't know where's the schema file for the MS Enterprise Library 4.0.

Update: After installing MS Enterprise Library, it seems there's no .xsd file. However, there's a tool for editing the configuration - EntLibConfig.exe, which you can use to edit the configuration files. Also, if you add the proper config sections to your config file, VS should be able to parse the config file properly. (EntLibConfig will add these for you, or you can add them yourself). Here's an example for the loggingConfiguration section:

<configSections>
    <section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
</configSections>

You also need to add a reference to the appropriate assembly in your project.

suptitle seems the way to go, but for what it's worth, the figure has a transFigure property that you can use:

fig=figure(1)
text(0.5, 0.95, 'test', transform=fig.transFigure, horizontalalignment='center')

Why not use memset()? That's how to do it.

Setting the first element leaves the rest of the memory untouched, but str functions will treat the data as empty.

The $number variables contain the parts of the string that matched the capture groups ( ... ) in the pattern for your last regex match if the match was successful.

For example, take the following string:

$text = "the quick brown fox jumps over the lazy dog.";

After the statement

$text =~ m/ (b.+?) /;

$1 equals the text "brown".

<div id="inner" tabindex="0">
    this div can now have focus and receive keyboard events
</div>

I think this will benefit you Try this I'm using to change the language in my application

String[] districts;
Spinner sp;

......

 sp = (Spinner) findViewById(R.id.sp);
         districts = getResources().getStringArray(R.array.lang_array);
         ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item,districts);
         sp.setAdapter(adapter);
         sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
              @Override
             public void onItemSelected(AdapterView<?> arg0, View arg1, int position, long arg3) {
                  // TODO Auto-generated method stub
                  int index = arg0.getSelectedItemPosition();
                  Toast.makeText(getBaseContext(), "You select "+districts[index]+" id "+position, Toast.LENGTH_LONG).show();
                  switch(position){
                      case 0:
                          setLocal("fr");
                          //recreate();
                          break;
                      case 1:
                          setLocal("ar");
                          //recreate();
                          break;
                      case 2:
                          setLocal("en");
                          //recreate();
                          break;
                      default: //For all other cases, do this
                          setLocal("en");
                          //recreate();
                          break;
                  }
              }
             @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                   // TODO Auto-generated method stub
                         }
        });

and this is my String Array

<string-array name="lang_array">
    <item>french</item>
    <item>arabic</item>
    <item>english</item>
</string-array>

Even shorter and with json-functions:

JSONObject songsObject = json.getJSONObject("songs");
JSONArray songsArray = songsObject.toJSONArray(songsObject.names());

First you need to do is run (replace with your port number):

fuser -k 3000/tcp

This will release the port. After you run the above command run:

service docker restart

And your problem is resolved.

One other thing to look out for is that XCode is badly handling the library imports, and in many cases the solution is to find the imported file in your project, delete it in Finder or from the command line and add it back again, otherwise it won't get properly updated by XCode. By XCode leaving there the old file you keep running in circles not understanding why it is not compiling, missing the architecture etc.

For Python 3 urllib3 works properly, you can use as follow as per its official docs :

import urllib3

http = urllib3.PoolManager()
response = http.request(
     'GET',
     'https://api.prylabs.net/eth/v1alpha1/beacon/attestations',
     fields={  # here fields are the query params
          'epoch': 1234,
          'pageSize': pageSize 
      } 
 )
response = attestations.data.decode('UTF-8')

The answer given above can't solve my problem.So I change async into false to get the alert message.

jQuery.ajax({
            type:"post",
            dataType:"json",
            async: false,
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                alert("Data was succesfully captured");
            },
        });

You can't use PHP to prevent a timeout issued by nginx.

To configure nginx to allow more time see the proxy_read_timeout directive.

In my case, this was caused by a subclass name being used in the very next line as a variable name with a different type:

var binGlow: pipGlow = pipGlow(style: "Bin")
var pipGlow: PipGlowSprite = PipGlowSprite()

Notice that in line 1, pipGlow is the name of the subclass (of SKShapeNode), but in line two, I was using pipGlow as a variable name. This was not only bad coding style, but apparently an outright no-no as well! Once I change the second line to:

var binGlow: pipGlow = pipGlow(style: "Bin")
var pipGlowSprite: PipGlowSprite = PipGlowSprite()

I no longer received the error. I hope this helps someone!

The problem in my case was in the discrepancy between the Gradle version installed globally and the one required by React Native. To fix it, I had to update the folder android/gradle/wrapper from the current 6.5 RN version from GH.

IE7 doesn't know inline-block. You must add:

display:inline;
zoom: 1;

nonatomic property means @synthesized methods are not going to be generated threadsafe -- but this is much faster than the atomic property since extra checks are eliminated.

strong is used with ARC and it basically helps you , by not having to worry about the retain count of an object. ARC automatically releases it for you when you are done with it.Using the keyword strong means that you own the object.

weak ownership means that you don't own it and it just keeps track of the object till the object it was assigned to stays , as soon as the second object is released it loses is value. For eg. obj.a=objectB; is used and a has weak property , than its value will only be valid till objectB remains in memory.

copy property is very well explained here

strong,weak,retain,copy,assign are mutually exclusive so you can't use them on one single object... read the "Declared Properties " section

hoping this helps you out a bit...

Use example

select ord_num, agent_code, ord_date, ord_amount  
from orders  
where(agent_code, ord_amount) IN  
(SELECT agent_code, MIN(ord_amount)  
FROM orders   
GROUP BY agent_code);    

And if you just want to get the directory name and no need for the filename coming with it, then you can do that in the following conventional way using os Python module.

>>> import os
>>> f = open('/Users/Desktop/febROSTER2012.xls')
>>> os.path.dirname(f.name)
>>> '/Users/Desktop/'

This way you can get hold of the directory structure.

On windows, you can use PuttyGen to load the private key file, remove the passphrase and then overwrite the existing private key file.

If you're using web components, then they have this as an example:

map.addEventListener('google-map-ready', function(e) {
   alert('Map loaded!');
});

maybe table innodb error after u reinstal or copy file db try to repair tbl innodb, if table cant be repair try delete db or table

xamppfiles/var/mysql/your db

or

xamppfiles/var/mysql/your db/your table

change permission folder to open folder database

before delete backup ur folder database

phpPgAdmin might work for you, if you're already familiar with phpMyAdmin.

Please note that development of phpPgAdmin has moved to github per this notice but the SourceForge link above is for historical / documentation purposes.

But really there are dozens of tools that can do this.

og_date = "2012-10-01";
console.log(og_date); // => "2012-10-01"

console.log(og_date.split('-')); // => [ '2012', '10', '01' ]

og_date.value would only work if the date were stored as a property on the og_date object. Such as: var og_date = {}; og_date.value="2012-10-01"; In that case, your original console.log would work.

Instead of the code you wrote, you may use ArrayList.addAll() to merge the lists, Collections.sort() to sort it and finally traverse of the resulting ArrayList to remove duplicates. The aggregate complexity is thus O(n)+O(n*log(n))+O(n) which is equivalent to O(n*log(n)).

Use "IF DEFINED variable command" to test variable in batch file.

But if you want to test batch parameters, try below codes to avoid tricky input (such as "1 2" or ab^>cd)

set tmp="%1"
if "%tmp:"=.%"==".." (
    echo empty
) else (
    echo not empty
)

Use moment-timezone

moment(date).tz('Europe/Berlin').format(format)

Before being able to access a particular timezone, you will need to load it like so (or using alternative methods described here)

moment.tz.add('Europe/Berlin|CET CEST CEMT|-10 -20 -30')

Generate a random number for the difference of min and max by using the nextint(n) method and then add min number to the result:

Random rn = new Random();
int result = rn.nextInt(max - min + 1) + min;
System.out.println(result);

A better way to do a break line is using span with CSS style parameter white-space: nowrap;

span.nobreak {
  white-space: nowrap;
}

or
span.nobreak {
  overflow: hidden;
  text-overflow: ellipsis;
  white-space: nowrap;
}

Example directly in your HTML

<span style='overflow:hidden; white-space: nowrap;'> YOUR EXTENSIVE TEXT THAT YOU CAN´T BREAK LINE ....</span>

There are errors in your meta tag.

Yours:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src: 'self' 'unsafe-inline' 'unsafe-eval'>

Corrected:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval'"/>

Note the colon after "script-src", and the end double-quote of the meta tag.

Your script is executing , you just can't use document.write from it. Use an alert to test it and avoid using document.write. The statements of your js file with document.write will not be executed and the rest of the function will be executed.

You cannot use the syntax you have suggested. If you have a C99 compiler, though, you can do this:

int *p;

p = malloc(3 * sizeof p[0]);
memcpy(p, (int []){ 0, 1, 2 }, 3 * sizeof p[0]);

If your compiler does not support C99 compound literals, you need to use a named template to copy from:

int *p;

p = malloc(3 * sizeof p[0]);
{
    static const int p_init[] = { 0, 1, 2 };
    memcpy(p, p_init, 3 * sizeof p[0]);
}

In intellij8 I was using a specific plugin "Jar Tool" that is configurable and allows to pack a JAR archive.

For me.. the problem was that the anchor needs a title, and that was missing!

First, I thought:

"...In Microsoft SQL Server the SELECT...INTO automatically creates the new table whereas Oracle seems to require you to manually create it before executing the SELECT...INTO statement..."

But after manually generating a table, it still did not work, still showing the "missing keyword" error.

So I gave up this time and solved it by first manually creating the table, then using the "classic" SELECT statement:

INSERT INTO assignment_20081120 SELECT * FROM assignment;

Which worked as expected. If anyone come up with an explanaition on how to use the SELECT...INTO in a correct way, I would be happy!

This is my summary of the above and works perfectly for me. Thanks for the info!

<script language='javascript' type='text/javascript'>
    $(document).ready(function () {
        var firstInput = $('form').find('input[type=text],input[type=password],input[type=radio],input[type=checkbox],textarea,select').filter(':visible:first');
        if (firstInput != null) {
            firstInput.focus();
        }
    });
</script>

In Python 3, you can use

"one" in d.values()

to test if "one" is among the values of your dictionary.

In Python 2, it's more efficient to use

"one" in d.itervalues()

instead.

Note that this triggers a linear scan through the values of the dictionary, short-circuiting as soon as it is found, so this is a lot less efficient than checking whether a key is present.

I strongly recommend using a combination of GitLens & GitGraph.

Below snapshot highlights how gitlens is showing commit over time

And the below picture is for the the amazing vivid GitGraph

• If you just want to sort the array values and don't care for the keys, use sort(). This will give a new array with numeric keys starting from 0.
• If you want to keep the key-value associations, use asort().

See also the comparison table of sorting functions in PHP.

Actually, the Robustness Diagrams (or Analysis Diagrams, as they are sometimes called) are just specialized Class Diagrams. They are a part of UML, and have been from the beginning (see Jacobson's book, The Unified Software Development Process - part of the "Three Amigos" series of books). The aforementioned book has a good definition of these three classes on pp 183-185.

Your issue here is that you're not understanding the scope that you're setting.

You are passing the ready function a function itself. Within this function, you're creating another function called codeAddress. This one exists within the scope that created it and not within the window object (where everything and its uncle could call it).

For example:

var myfunction = function(){
    var myVar = 12345;
};

console.log(myVar); // 'undefined' - since it is within 
                    // the scope of the function only.

Have a look here for a bit more on anonymous functions: http://www.adequatelygood.com/2010/3/JavaScript-Module-Pattern-In-Depth

Another thing is that I notice you're using jQuery on that page. This makes setting click handlers much easier and you don't need to go into the hassle of setting the 'onclick' attribute in the HTML. You also don't need to make the codeAddress method available to all:

$(function(){
    $("#imgid").click(function(){
        var address = $("#formatedAddress").value;
        geocoder.geocode( { 'address': address}, function(results, status) {
           if (status == google.maps.GeocoderStatus.OK) {
             map.setCenter(results[0].geometry.location);
           }
        });
    });  
});

(You should remove the existing onclick and add an ID to the image element that you want to handle)

Note that I've replaced $(document).ready() with its shortcut of just $() (http://api.jquery.com/ready/). Then the click method is used to assign a click handler to the element. I've also replaced your document.getElementById with the jQuery object.

If you have seaborn installed, an easier method that does not require you to perform pivot:

import seaborn as sns

sns.lineplot(data=df, x='x', y='y', hue='color')

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

I am using ng-class for adding style :-

 ng-class="column.label=='Description'  ? 'tableStyle':                     
           column.label == 'Markdown Type' ? 'Mtype' : 
           column.label == 'Coupon Number' ? 'couponNur' :  ''
           "

Using ternary operator along with ng-class directives in angular.js for giving style. Then define the style for class in .css or .scss file. Eg :-

.Mtype{
       width: 90px !important;
       min-width: 90px !important;
       max-width: 90px !important;
      }
.tableStyle{
         width: 129px !important;
         min-width: 129px !important;
         max-width: 129px !important;
}
.couponNur{
         width: 250px !important;
         min-width: 250px !important;
         max-width: 250px !important;
}

I'm not so comfortable with regular expressions, and my example results from a datetimepicker field formatted m/d/Y h:mA. In this legal example, you have to arrive before the actual deposition hearing. I use replace function to clean up the dates so that I can process them as Date objects and compare them.

function compareDateTimes() {
    //date format ex "04/20/2017 01:30PM"
    //the problem is that this format results in Invalid Date
    //var d0 = new Date("04/20/2017 01:30PM"); => Invalid Date

    var start_date = $(".letter #depo_arrival_time").val();
    var end_date = $(".letter #depo_dateandtime").val();

    if (start_date=="" || end_date=="") {
        return;
    }

Not sure whether I miss the point, but I think none of the answers here are "simple" state machines. What i usually call a simple state machine is using a loop with a switch inside. That is what we used in PLC / microchip programming or in C/C++ programming at the university.

advantages:

• easy to write. no special objects and stuff required. you dont even need object orientation for it.
• when it is small, it is easy to understand.

disadvantages:

• can become quite big and hard to read, when there are many states.

It looked like that:

public enum State
{
    First,
    Second,
    Third,
}

static void Main(string[] args)
{
    var state = State.First;
    // x and i are just examples for stuff that you could change inside the state and use for state transitions
    var x     = 0; 
    var i     = 0;

    // does not have to be a while loop. you could loop over the characters of a string too
    while (true)  
    {
        switch (state)
        {
            case State.First:
                // Do sth here
                if (x == 2)
                    state = State.Second;  
                    // you may or may not add a break; right after setting the next state
                // or do sth here
                if (i == 3)
                    state = State.Third;
                // or here
                break;
            case State.Second:
                // Do sth here
                if (x == 10)
                    state = State.First;
                // or do sth here
                break;
            case State.Third:
                // Do sth here
                if (x == 10)
                    state = State.First;
                // or do sth here
                break;
            default:
                // you may wanna throw an exception here.
                break;
        }
    }
}

if it should be really a state machine on which you call methods which react depending on which state you are in differently: state design pattern is the better approach

Join like this:

ON a.userid = b.sourceid AND a.listid = b.destinationid;

To use the hex encoding in Python 3, use

>>> import codecs
>>> codecs.encode(b"c", "hex")
b'63'

In legacy Python, there are several other ways of doing this:

>>> hex(ord("c"))
'0x63'
>>> format(ord("c"), "x")
'63'
>>> "c".encode("hex")
'63'

If you can use Python, it is even easier if you have the pyopenssl module. Here it is:

from OpenSSL import crypto

# May require "" for empty password depending on version

with open("push.p12", "rb") as file:
    p12 = crypto.load_pkcs12(file.read(), "my_passphrase")

# PEM formatted private key
print crypto.dump_privatekey(crypto.FILETYPE_PEM, p12.get_privatekey())

# PEM formatted certificate
print crypto.dump_certificate(crypto.FILETYPE_PEM, p12.get_certificate())

Depending on your privileges, this query might work:

SELECT sqltext.TEXT,
req.session_id,
req.status,
req.command,
req.cpu_time,
req.total_elapsed_time
FROM sys.dm_exec_requests req
CROSS APPLY sys.dm_exec_sql_text(sql_handle) AS sqltext

Rijndael/AES is a block cypher. It encrypts data in 128 bit (16 character) blocks. Cryptographic padding is used to make sure that the last block of the message is always the correct size.

Your decryption method is expecting whatever its default padding is, and is not finding it. As @NetSquirrel says, you need to explicitly set the padding for both encryption and decryption. Unless you have a reason to do otherwise, use PKCS#7 padding.

What's so confusing about it... getters are functions that are called when you get a property, setters, when you set it. example, if you do

obj.prop = "abc";

You're setting the property prop, if you're using getters/setters, then the setter function will be called, with "abc" as an argument. The setter function definition inside the object would ideally look something like this:

set prop(var) {
   // do stuff with var...
}

I'm not sure how well that is implemented across browsers. It seems Firefox also has an alternative syntax, with double-underscored special ("magic") methods. As usual Internet Explorer does not support any of this.

Hit enter as there is no password. Enter the following commands:

mysql> SET PASSWORD for 'root'@'localhost' = password('enteryourpassword');
mysql> SET PASSWORD for 'root'@'127.0.0.1' = password('enteryourpassword');
mysql> SET PASSWORD for 'root'@'::1' = password('enteryourpassword');

That’s it, I keep the passwords the same to keep things simple. If you want to check the user’s table to see that the info has been updated just enter the additional commands as shown below. This is a good option to check that you have indeed entered the same password for all hosts.

Actually, this is not a design flaw, and it is not because of internals, or performance.
It comes simply from the fact that functions in Python are first-class objects, and not only a piece of code.

As soon as you get to think into this way, then it completely makes sense: a function is an object being evaluated on its definition; default parameters are kind of "member data" and therefore their state may change from one call to the other - exactly as in any other object.

In any case, Effbot has a very nice explanation of the reasons for this behavior in Default Parameter Values in Python.
I found it very clear, and I really suggest reading it for a better knowledge of how function objects work.

If you want to set cookie and get it outside of request, Laravel is not your friend.

Laravel cookies are part of Request, so if you want to do this outside of Request object, use good 'ole PHP setcookie(..) and $_COOKIE to get it.

I modified Neutrino's solution to make the xaml look less verbose when specifying the value:

Sorry for no pictures of the rendered xaml, just imagine a [=] hamburger button that you click and it turns into [<-] a back button and also toggles the visibility of a Grid.

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

...

<Grid>
    <Button x:Name="optionsButton">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Visible" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Hamburger Width="10" Height="10" />
    </Button>

    <Button x:Name="optionsBackButton" Visibility="Collapsed">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Collapsed" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Back Width="12" Height="11" />
    </Button>
</Grid>

...

<Grid Grid.RowSpan="2" x:Name="optionsPanel" Visibility="Collapsed">

</Grid>

You can also specify values this way like in Neutrino's solution:

<Button x:Name="optionsButton">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <local:SetterAction PropertyName="Visibility" Value="{x:Static Visibility.Collapsed}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="{x:Static Visibility.Visible}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="{x:Static Visibility.Visible}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

    <glyphs:Hamburger Width="10" Height="10" />
</Button>

So let's fully understand, Let's say you have a query which works in localhost but does not in production mode, This is because in MySQL 5.7 and above they decided to activate the sql_mode=only_full_group_by by default, basically it is a strict mode which prevents you to select non aggregated fields.

Here's the query (works in local but not in production mode) :

SELECT post.*, YEAR(created_at) as year
FROM post
GROUP BY year

SELECT post.id, YEAR(created_at) as year  // This will generate an error since there are many ids
FROM post
GROUP BY year

To verify if the sql_mode=only_full_group_by is activated for, you should execute the following query :

SELECT @@sql_mode;   //localhost

Output : IGNORE_SPACE, STRICT_TRANS, ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION (If you don't see it, it means it is deactivated)

But if try in production mode, or somewhere where it gives you the error it should be activated:

SELECT @@sql_mode;   //production

Output: ONLY_FULL_GROUP_BY, STRICT_TRANS_TABLES, NO_ZERO_IN_DATE, NO_ZERO... And it's ONLY_FULL_GROUP_BY we're looking for here.

Otherwise, if you are using phpMyAdmin then go to -> Variables and search for sql_mode

Let's take our previous example and adapt it to it :

SELECT MIN(post.id), YEAR(created_at) as year  //Here we are solving the problem with MIN()
FROM post
GROUP BY year

And the same for MAX()

And if we want all the IDs, we're going to need:

SELECT GROUP_CONCAT(post.id SEPARATOR ','), YEAR(created_at) as year
FROM post
GROUP BY year

or another newly added function:

SELECT ANY_VALUE(post.id), YEAR(created_at) as year 
FROM post
GROUP BY year

?? ANY_VALUE does not exist for MariaDB

And If you want all the fields, then you could use the same:

SELECT ANY_VALUE(post.id), ANY_VALUE(post.slug), ANY_VALUE(post.content) YEAR(created_at) as year 
FROM post
GROUP BY year

? To deactivate the sql_mode=only_full_group_by then you'll need to execute this query:

SET GLOBAL sql_mode=(SELECT REPLACE(@@sql_mode, 'ONLY_FULL_GROUP_BY', ''));

Sorry for the novel, hope it helps.

<script src="test.js?random=<?php echo uniqid(); ?>"></script>

EDIT: Or you could use the file modification time so that it's cached on the client.

<script src="test.js?random=<?php echo filemtime('test.js'); ?>"></script>

If the usage pattern justifies it, why not? While your team doesn't recognize the operator right away, with time they could. Humans learn new words all the time. Why not in programming?

The only caution I might state is that "^" doesn't have the short circuit semantics of your second boolean check. If you really need the short circuit semantics, then a static util method works too.

public static boolean xor(boolean a, boolean b) {
    return (a && !b) || (b && !a);
}

 extension UITextField {  
  func setBottomBorder(color:String) {
    self.borderStyle = UITextBorderStyle.None
    let border = CALayer()
    let width = CGFloat(1.0)
    border.borderColor = UIColor(hexString: color)!.cgColor
    border.frame = CGRect(x: 0, y: self.frame.size.height - width,   width:  self.frame.size.width, height: self.frame.size.height)
    border.borderWidth = width
    self.layer.addSublayer(border)
    self.layer.masksToBounds = true
   }
}

and then just do this:

yourTextField.setBottomBorder(color: "#3EFE46")

How about

SELECT *
FROM Employees
WHERE PhoneNumber IN (
    SELECT PhoneNumber
    FROM Employees
    GROUP BY PhoneNumber
    HAVING COUNT(Employee_ID) > 1
    )

SQL Fiddle DEMO

Use this:

printf ("%.2f", 3.14159);

string Time = "16:23:01";
DateTime date = DateTime.Parse(Time, System.Globalization.CultureInfo.CurrentCulture);

string t = date.ToString("HH:mm:ss tt");

The problem is that omega in your case is matrix of dimensions 1 * 1. You should convert it to a vector if you wish to multiply t(X) %*% X by a scalar (that is omega)

In particular, you'll have to replace this line:

omega   = rgamma(1,a0,1) / L0

with:

omega   = as.vector(rgamma(1,a0,1) / L0)

everywhere in your code. It happens in two places (once inside the loop and once outside). You can substitute as.vector(.) or c(t(.)). Both are equivalent.

Here's the modified code that should work:

gibbs = function(data, m01 = 0, m02 = 0, k01 = 0.1, k02 = 0.1, 
                     a0 = 0.1, L0 = 0.1, nburn = 0, ndraw = 5000) {
    m0      = c(m01, m02) 
    C0      = matrix(nrow = 2, ncol = 2) 
    C0[1,1] = 1 / k01 
    C0[1,2] = 0 
    C0[2,1] = 0 
    C0[2,2] = 1 / k02 
    beta    = mvrnorm(1,m0,C0) 
    omega   = as.vector(rgamma(1,a0,1) / L0)
    draws   = matrix(ncol = 3,nrow = ndraw) 
    it      = -nburn 

    while (it < ndraw) {
        it    = it + 1 
        C1    = solve(solve(C0) + omega * t(X) %*% X) 
        m1    = C1 %*% (solve(C0) %*% m0 + omega * t(X) %*% y)
        beta  = mvrnorm(1, m1, C1) 
        a1    = a0 + n / 2 
        L1    = L0 + t(y - X %*% beta) %*% (y - X %*% beta) / 2 
        omega = as.vector(rgamma(1, a1, 1) / L1)
        if (it > 0) { 
            draws[it,1] = beta[1]
            draws[it,2] = beta[2]
            draws[it,3] = omega
        }
    }
    return(draws)
}

returning true or false indicates that whether execution should continue or stop right there. So just an example

<input type="button" onclick="return func();" />

Now if func() is defined like this

function func()
{
 // do something
return false;
}

the click event will never get executed. On the contrary if return true is written then the click event will always be executed.

Have you tried using?:

left:50%;
top:50%;
margin-left:-[half the width] /* As pointed out on the comments by Chetan Sastry */

Not sure if it'll work, but it's worth a try...

Minor edit: Added the margin-left part, as pointed out on the comments by Chetan...

There are several ways to do this:

A simple way is using the os module:

import os
os.system("ls -l")

More complex things can be achieved with the subprocess module: for example:

import subprocess
test = subprocess.Popen(["ping","-W","2","-c", "1", "192.168.1.70"], stdout=subprocess.PIPE)
output = test.communicate()[0]

In my case i forgot to add the () after the function name inside the render function of a react component

public render() {
       let ctrl = (
           <>
                <div className="aaa">
                    {this.renderView}
                </div>
            </>
       ); 

       return ctrl;
    };


    private renderView() : JSX.Element {
        // some html
    };

Changing the render method, as it states in the error message to

        <div className="aaa">
            {this.renderView()}
        </div>

fixed the problem

I added the start and exit which works. Without both it was not working

start C:/Anaconda3/Library/bin/pyrcc4.exe -py3 {path}/Resourses.qrc -{path}/Resourses_rc.py
exit

Try

System.getProperty("user.dir")

It returns the current working directory.

How about print (x, y) at once.

from matplotlib import pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)

A = -0.75, -0.25, 0, 0.25, 0.5, 0.75, 1.0
B = 0.73, 0.97, 1.0, 0.97, 0.88, 0.73, 0.54

plt.plot(A,B)
for xy in zip(A, B):                                       # <--
    ax.annotate('(%s, %s)' % xy, xy=xy, textcoords='data') # <--

plt.grid()
plt.show()

UPDATE: Somebody just won't take no as the answer, and I like it, very much, especially to this particular question.

GOOD NEWS, There is a way now --

The solution is Rocker: https://github.com/grammarly/rocker

John Yani said, "IMO, it solves all the weak points of Dockerfile, making it suitable for development."

Rocker

https://github.com/grammarly/rocker

By introducing new commands, Rocker aims to solve the following use cases, which are painful with plain Docker:

1. Mount reusable volumes on build stage, so dependency management tools may use cache between builds.
2. Share ssh keys with build (for pulling private repos, etc.), while not leaving them in the resulting image.
3. Build and run application in different images, be able to easily pass an artifact from one image to another, ideally have this logic in a single Dockerfile.
4. Tag/Push images right from Dockerfiles.
5. Pass variables from shell build command so they can be substituted to a Dockerfile.

And more. These are the most critical issues that were blocking our adoption of Docker at Grammarly.

Update: Rocker has been discontinued, per the official project repo on Github

As of early 2018, the container ecosystem is much more mature than it was three years ago when this project was initiated. Now, some of the critical and outstanding features of rocker can be easily covered by docker build or other well-supported tools, though some features do remain unique to rocker. See https://github.com/grammarly/rocker/issues/199 for more details.

This one will allow also for signed and float numbers or empty string:

var reg = /^-?\d*\.?\d*$/

If you don't want allow to empty string use this one:

var reg = /^-?\d+\.?\d*$/

Are you using .NET 3.5? You could use the ZipPackage class and related classes. Its more than just zipping up a file list because it wants a MIME type for each file you add. It might do what you want.

I'm currently using these classes for a similar problem to archive several related files into a single file for download. We use a file extension to associate the download file with our desktop app. One small problem we ran into was that its not possible to just use a third-party tool like 7-zip to create the zip files because the client side code can't open it -- ZipPackage adds a hidden file describing the content type of each component file and cannot open a zip file if that content type file is missing.

If you just want to see the image on your local browser, this can be done if you have a server running locally. You just need to reference the local server via http (not file://), like:

http://localhost/my_picture.jpg

if picture.jpg is in your local server's webroot folder. You can do this for any site if you open your browser's developer tools and change the img element's src attribute to the local server's URL for the image. If you have access to the HTML of your site, then change it there. But obviously if someone not on your local computer/server accesses the site, they will get a broken image unless they happen to be running a local server as well and have an image with the same filename, which would be weird.

Try explicitly enumerating the results by calling ToList().

Change

foreach (var item in query)

to

foreach (var item in query.ToList())

try instead:

if not os.path.exists(pathName):
    do this

Here's the Java code using registerDefaultNetworkCallback (and registerNetworkCallback for API < 24):

ConnectivityManager.NetworkCallback networkCallback = new ConnectivityManager.NetworkCallback() {
    @Override
    public void onAvailable(Network network) {
        // network available
    }

    @Override
    public void onLost(Network network) {
        // network unavailable
    }
};

ConnectivityManager connectivityManager =
        (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
    connectivityManager.registerDefaultNetworkCallback(networkCallback);
} else {
    NetworkRequest request = new NetworkRequest.Builder()
            .addCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET).build();
    connectivityManager.registerNetworkCallback(request, networkCallback);
}

The reason your functor example does not work is that you need an instance to invoke the operator().

As of jQuery version 1.7, the off() method is the new replacement for the unbind(), die() and undelegate() methods. This method brings a lot of consistency to the API, and we recommend that you use this method, as it simplifies the jQuery code base.

This gives:

$("#someid").off("click").live("click",function(){...

or

$("#someid").off("click").bind("click",function(){...

My situation was a little different. The solution was to strip the .pem from everything outside of the CERTIFICATE and PRIVATE KEY sections and to invert the order which they appeared. After converting from pfx to pem file, the certificate looked like this:

Bag Attributes
localKeyID: ...
issuer=...
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----
Bag Attributes
more garbage...
-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----

After correcting the file, it was just:

-----BEGIN PRIVATE KEY-----
...
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----

For future googlers, in 2016 there is a browser safe pure CSS way of hiding empty images using the attribute selector:

img[src="Error.src"] {
    display: none;
}

Edit: I'm back - for future googlers, in 2019 there is a way to style the actual alt text and alt text image in the Shadow Dom, but it only works in developer tools. So you can't use it. Sorry. It would be so nice.

#alttext-container {
    opacity: 0;
}
#alttext-image {
    opacity: 0;
}
#alttext {
    opacity: 0;
}

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();
