For me was because I put the animation name inside square brackets.

<div [@animation]></div>

But after I removed the bracket all worked fine (In Angular 9.0.1):

<div @animation></div>

this is how I implement it .

let dictionary = self.convertStringToDictionary(responceString)            
     NotificationCenter.default.post(name: NSNotification.Name(rawValue: "SOCKET_UPDATE"), object: dictionary)

Well, one thing that worked for me is using physical android device instead of emulator. As in my PC( i5 and 4GB RAM ) the android studio takes about 700MB of memory and the emulator takes another 700. Thus the whole performance of the computer goes down. Working with a physical device saves the strain from the emulator.

Add the following css to disable the default scroll:

body {
    overflow: hidden;
}

And change the #content css to this to make the scroll only on content body:

#content {
    max-height: calc(100% - 120px);
    overflow-y: scroll;
    padding: 0px 10%;
    margin-top: 60px;
}

See fiddle here.

Edit:

Actually, I'm not sure what was the issue you were facing, since it seems that your css is working. I have only added the HTML and the header css statement:

html {_x000D_
  height: 100%;_x000D_

For anyone struggling with this issue using bootstrap3 use the below classlist. If you've copy pasted from the DOC, It won't surely work. Becasue of the .show in new version.

<div class="tab-pane fade in active" >

<div class="tab-pane fade in" >

Updated Answer

Trying to open multiple panels of a collapse control that is setup as an accordion i.e. with the data-parent attribute set, can prove quite problematic and buggy (see this question on multiple panels open after programmatically opening a panel)

Instead, the best approach would be to:

1. Allow each panel to toggle individually
2. Then, enforce the accordion behavior manually where appropriate.

To allow each panel to toggle individually, on the data-toggle="collapse" element, set the data-target attribute to the .collapse panel ID selector (instead of setting the data-parent attribute to the parent control. You can read more about this in the question Modify Twitter Bootstrap collapse plugin to keep accordions open.

Roughly, each panel should look like this:

<div class="panel panel-default">
   <div class="panel-heading">
         <h4 class="panel-title"
             data-toggle="collapse" 
             data-target="#collapseOne">
             Collapsible Group Item #1
         </h4>
    </div>
    <div id="collapseOne" 
         class="panel-collapse collapse">
        <div class="panel-body"></div>
    </div>
</div>

To manually enforce the accordion behavior, you can create a handler for the collapse show event which occurs just before any panels are displayed. Use this to ensure any other open panels are closed before the selected one is shown (see this answer to multiple panels open). You'll also only want the code to execute when the panels are active. To do all that, add the following code:

$('#accordion').on('show.bs.collapse', function () {
    if (active) $('#accordion .in').collapse('hide');
});

Then use show and hide to toggle the visibility of each of the panels and data-toggle to enable and disable the controls.

$('#collapse-init').click(function () {
    if (active) {
        active = false;
        $('.panel-collapse').collapse('show');
        $('.panel-title').attr('data-toggle', '');
        $(this).text('Enable accordion behavior');
    } else {
        active = true;
        $('.panel-collapse').collapse('hide');
        $('.panel-title').attr('data-toggle', 'collapse');
        $(this).text('Disable accordion behavior');
    }
});

Working demo in jsFiddle

try to implement Application_AuthenticateRequest instead of Application_Start.

this method has an instance for HttpContext.Current, unlike Application_Start (which fires very soon in app lifecycle, soon enough to not hold a HttpContext.Current object yet).

hope that helps.

FWIW, in Boostrap 4.4, you can add .text-wrap style to things like buttons:

   <a href="#" class="btn btn-primary text-wrap">Lorem ipsum dolor sit amet, consectetur adipiscing elit.</a>

https://getbootstrap.com/docs/4.4/utilities/text/#text-wrapping-and-overflow

Ok, there are two possible approaches. The simplest - is to use a sliding menu library. It allows creating a bottom sliding menu, it can animate the top container to make bottom visible, it suports both dragging it with your finger, or animating it programmatically via button (StaticDrawer).

Harder way - if you want to use Animations, as was already suggested. With animations you must FIRST change your layouts. So try first to make your layout change to the final state without any animations whatsoever. Because it is very likely that you are not laying out your views properly in RelativeLayout, so even though you show your bottom view, it remains obscured by the top one. Once you achieved proper layout change - all you need to do is to is to remember translations before layout and apply translate animation AFTER layout.

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

The problem is the indexing subplot is using. Subplots are counted starting with 1! Your code thus needs to read

fig=plt.figure(figsize=(15, 6),facecolor='w', edgecolor='k')
for i in range(10):

    #this part is just arranging the data for contourf 
    ind2 = py.find(zz==i+1)
    sfr_mass_mat = np.reshape(sfr_mass[ind2],(pixmax_x,pixmax_y))
    sfr_mass_sub = sfr_mass[ind2]
    zi = griddata(massloclist, sfrloclist, sfr_mass_sub,xi,yi,interp='nn')


    temp = 251+i  # this is to index the position of the subplot
    ax=plt.subplot(temp)
    ax.contourf(xi,yi,zi,5,cmap=plt.cm.Oranges)
    plt.subplots_adjust(hspace = .5,wspace=.001)

    #just annotating where each contour plot is being placed
    ax.set_title(str(temp))

Note the change in the line where you calculate temp

The JPanel is actually only a container where you can put different elements in it (even other JPanels). So in your case I would suggest one big JPanel as some sort of main container for your window. That main panel you assign a Layout that suits your needs ( here is an introduction to the layouts).

After you set the layout to your main panel you can add the paint panel and the other JPanels you want (like those with the text in it..).

  JPanel mainPanel = new JPanel();
  mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS));

  JPanel paintPanel = new JPanel();
  JPanel textPanel = new JPanel();

  mainPanel.add(paintPanel);
  mainPanel.add(textPanel);

This is just an example that sorts all sub panels vertically (Y-Axis). So if you want some other stuff at the bottom of your mainPanel (maybe some icons or buttons) that should be organized with another layout (like a horizontal layout), just create again a new JPanel as a container for all the other stuff and set setLayout(new BoxLayout(mainPanel, BoxLayout.X_AXIS).

As you will find out, the layouts are quite rigid and it may be difficult to find the best layout for your panels. So don't give up, read the introduction (the link above) and look at the pictures – this is how I do it :)

Or you can just use NetBeans to write your program. There you have a pretty easy visual editor (drag and drop) to create all sorts of Windows and Frames. (only understanding the code afterwards is ... tricky sometimes.)

EDIT

Since there are some many people interested in this question, I wanted to provide a complete example of how to layout a JFrame to make it look like OP wants it to.

The class is called MyFrame and extends swings JFrame

public class MyFrame extends javax.swing.JFrame{

    // these are the components we need.
    private final JSplitPane splitPane;  // split the window in top and bottom
    private final JPanel topPanel;       // container panel for the top
    private final JPanel bottomPanel;    // container panel for the bottom
    private final JScrollPane scrollPane; // makes the text scrollable
    private final JTextArea textArea;     // the text
    private final JPanel inputPanel;      // under the text a container for all the input elements
    private final JTextField textField;   // a textField for the text the user inputs
    private final JButton button;         // and a "send" button

    public MyFrame(){

        // first, lets create the containers:
        // the splitPane devides the window in two components (here: top and bottom)
        // users can then move the devider and decide how much of the top component
        // and how much of the bottom component they want to see.
        splitPane = new JSplitPane();

        topPanel = new JPanel();         // our top component
        bottomPanel = new JPanel();      // our bottom component

        // in our bottom panel we want the text area and the input components
        scrollPane = new JScrollPane();  // this scrollPane is used to make the text area scrollable
        textArea = new JTextArea();      // this text area will be put inside the scrollPane

        // the input components will be put in a separate panel
        inputPanel = new JPanel();
        textField = new JTextField();    // first the input field where the user can type his text
        button = new JButton("send");    // and a button at the right, to send the text

        // now lets define the default size of our window and its layout:
        setPreferredSize(new Dimension(400, 400));     // let's open the window with a default size of 400x400 pixels
        // the contentPane is the container that holds all our components
        getContentPane().setLayout(new GridLayout());  // the default GridLayout is like a grid with 1 column and 1 row,
        // we only add one element to the window itself
        getContentPane().add(splitPane);               // due to the GridLayout, our splitPane will now fill the whole window

        // let's configure our splitPane:
        splitPane.setOrientation(JSplitPane.VERTICAL_SPLIT);  // we want it to split the window verticaly
        splitPane.setDividerLocation(200);                    // the initial position of the divider is 200 (our window is 400 pixels high)
        splitPane.setTopComponent(topPanel);                  // at the top we want our "topPanel"
        splitPane.setBottomComponent(bottomPanel);            // and at the bottom we want our "bottomPanel"

        // our topPanel doesn't need anymore for this example. Whatever you want it to contain, you can add it here
        bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.Y_AXIS)); // BoxLayout.Y_AXIS will arrange the content vertically

        bottomPanel.add(scrollPane);                // first we add the scrollPane to the bottomPanel, so it is at the top
        scrollPane.setViewportView(textArea);       // the scrollPane should make the textArea scrollable, so we define the viewport
        bottomPanel.add(inputPanel);                // then we add the inputPanel to the bottomPanel, so it under the scrollPane / textArea

        // let's set the maximum size of the inputPanel, so it doesn't get too big when the user resizes the window
        inputPanel.setMaximumSize(new Dimension(Integer.MAX_VALUE, 75));     // we set the max height to 75 and the max width to (almost) unlimited
        inputPanel.setLayout(new BoxLayout(inputPanel, BoxLayout.X_AXIS));   // X_Axis will arrange the content horizontally

        inputPanel.add(textField);        // left will be the textField
        inputPanel.add(button);           // and right the "send" button

        pack();   // calling pack() at the end, will ensure that every layout and size we just defined gets applied before the stuff becomes visible
    }

    public static void main(String args[]){
        EventQueue.invokeLater(new Runnable(){
            @Override
            public void run(){
                new MyFrame().setVisible(true);
            }
        });
    }
}

Please be aware that this is only an example and there are multiple approaches to layout a window. It all depends on your needs and if you want the content to be resizable / responsive. Another really good approach would be the GridBagLayout which can handle quite complex layouting, but which is also quite complex to learn.

try this

<div ng-app="myApp" ng-controller="customersCtrl"> 
  <div ng-include="'myTable.htm'"></div>
</div>

<script>
var app = angular.module('myApp', []);
app.controller('customersCtrl', function($scope, $http) {
    $http.get("customers.php").then(function (response) {
        $scope.names = response.data.records;
    });
});
</script>

this is a reference for the DOM element for which the event is being handled (the current target). event.target refers to the element which initiated the event. They were the same in this case, and can often be, but they aren't necessarily always so.

You can get a good sense of this by reviewing the jQuery event docs, but in summary:

event.currentTarget

The current DOM element within the event bubbling phase.

event.delegateTarget

The element where the currently-called jQuery event handler was attached.

event.relatedTarget

The other DOM element involved in the event, if any.

event.target

The DOM element that initiated the event.

To get the desired functionality using jQuery, you must wrap it in a jQuery object using either: $(this) or $(evt.target).

The .attr() method only works on a jQuery object, not on a DOM element. $(evt.target).attr('href') or simply evt.target.href will give you what you want.

My friend that's very simple, here an example:

<dependency>
    <groupId>xalan</groupId>
    <artifactId>xalan</artifactId>
    <version>2.7.2</version>
    <scope>${my-scope}</scope>
    <exclusions>
        <exclusion>
        <groupId>xml-apis</groupId>
        <artifactId>xml-apis</artifactId>
    </exclusion>
</dependency>

And if you want to check in the terminal(windows console for this example) that your maven tree has no problems:

mvn dependency:tree -Dverbose | grep --color=always '(.* conflict\|^' | less -r

I liked Arthur's idea of a reusable handler, but I think there's a simpler way to do it:

private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
    if (sender.GetType() != typeof (Hyperlink))
        return;
    string link = ((Hyperlink) sender).NavigateUri.ToString();
    Process.Start(link);
}

Obviously there could be security risks with starting any kind of process, so be carefull.

Add this to your main CSS:

table td {
    border-top: none !important;
}

Use this for newer versions of bootstrap:

.table th, .table td { 
     border-top: none !important; 
 }

This actually works for me:

background-color: #6DB3F2;
background-image: url('images/checked.png');

You can also drop a solid shadow and set the background image:

background-image: url('images/checked.png');
box-shadow: inset 0 0 100% #6DB3F2;

If the first option is not working for some reason and you don't want to use the box shadow you can always use a pseudo element for the image without any extra HTML:

.btn{
    position: relative;
    background-color: #6DB3F2;
}
.btn:before{
    content: "";
    display: block;
    width: 100%;
    height: 100%;
    position:absolute;
    top:0;
    left:0;
    background-image: url('images/checked.png');
}

Had this problem when using AsyncFileUploader in an iFrame. Error came when using firefox. Worked in chrome just fine. It seemed like either the parent page or iframe page was loading out of sync and the parent page could not find the controls on the iframe page. Added a simple javascript alert to say that the file was uploaded. This gave the controls enough time to load and since the controls were available, everything loaded without an error.

The apps UI only works for panels.

The best you can do is to draw a button yourself and put that into your spreadsheet. Than you can add a macro to it.

Go into "Insert > Drawing...", Draw a button and add it to the spreadsheet. Than click it and click "assign Macro...", then insert the name of the function you wish to execute there. The function must be defined in a script in the spreadsheet.

Alternatively you can also draw the button somewhere else and insert it as an image.

More info: https://developers.google.com/apps-script/guides/menus

try http://code.google.com/p/swinghtmltemplate/

this will allow you to create gui with html-like syntax

JPanel p=new JPanel();  
GridBagLayout layout=new GridBagLayout(); 
p.setLayout(layout); 
GridBagConstraints gbc = new GridBagConstraints();
gbc.fill=GridBagConstraints.HORIZONTAL; 
gbc.gridx=0;   
gbc.gridy=0;   
p2.add("",gbc);

The simplest way I have found to run task synchronously and without blocking UI thread is to use RunSynchronously() like:

Task t = new Task(() => 
{ 
   //.... YOUR CODE ....
});
t.RunSynchronously();

In my case, I have an event that fires when something occurs. I dont know how many times it will occur. So, I use code above in my event, so whenever it fires, it creates a task. Tasks are executed synchronously and it works great for me. I was just surprised that it took me so long to find out of this considering how simple it is. Usually, recommendations are much more complex and error prone. This was it is simple and clean.

If you want to hide panel on button click, write below code in JButton Action. I assume you want to hide jpanel1.

jpanel1.setVisible(false);

private Point FindLocation(Control ctrl)
{
    if (ctrl.Parent is Form)
        return ctrl.Location;
    else
    {
        Point p = FindLocation(ctrl.Parent);
        p.X += ctrl.Location.X;
        p.Y += ctrl.Location.Y;
        return p;
    }
}

After implementing the accepted answer I did run across an issue that when navigating views with Prism the TextBox would still not get focus. A minor change to the PropertyChanged handler resolved it

    private static void OnIsFocusedPropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var uie = (UIElement)d;
        if ((bool)e.NewValue)
        {
            uie.Dispatcher.BeginInvoke(DispatcherPriority.Input, new Action(() =>
            {
                uie.Focus();
            }));
        }
    }

To all: don't forget about case MotionEvent.ACTION_CANCEL:

it calls in 30% swipes without ACTION_UP

and its equal to ACTION_UP in this case

If you are working with SQL 2008 R2 then from View---->Report Data option at bottom

FWIW, I experienced a similar issue w/mootools. Re-attaching my events was the correct move, but needed to be done at the end of the request..eg

var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_endRequest(function() {... 

Just something to keep in mind if beginRequest causes you to get null reference JS exceptions.

You can install ECMerge diff/merge tool on your Linux, Mac or Windows. It is pre-configured in Git, so just using git mergetool will do the job.

Recursion is a fancy way of saying "Do this thing again until its done".

Two important things to have:

1. A base case - You've got a goal to get to.
2. A test - How to know if you've got to where you're going.

Imagine a simple task: Sort a stack of books alphabetically. A simple process would be take the first two books, sort them. Now, here comes the recursive part: Are there more books? If so, do it again. The "do it again" is the recursion. The "are there any more books" is the test. And "no, no more books" is the base case.

To uninstall Ionic and Cordova:

sudo npm uninstall -g cordova
sudo npm uninstall -g ionic

To install:

sudo npm install -g cordova

You can use the command time /t for the time and date /t for the date, here is an example:

@echo off
time /t >%tmp%\time.tmp
date /t >%tmp%\date.tmp
set ttime=<%tmp%\time.tmp
set tdate=<%tmp%\date.tmp
del /f /q %tmp%\time.tmp
del /f /q %tmp%\date.tmp
echo Time: %ttime%
echo Date: %tdate%
pause >nul

You can also use the built in variables %time% and %date%, here is another example:

@echo off
echo Time: %time:~0,5%
echo Date: %date%
pause >nul

Running commands periodically without cron is possible when we go with while.

As a command:

while true ; do command ; sleep 100 ; done &
[ ex: # while true;  do echo `date` ; sleep 2 ; done & ]

Example:

while true
do echo "Hello World"
sleep 100
done &

Do not forget the last & as it will put your loop in the background. But you need to find the process id with command "ps -ef | grep your_script" then you need to kill it. So kindly add the '&' when you running the script.

# ./while_check.sh &

Here is the same loop as a script. Create file "while_check.sh" and put this in it:

#!/bin/bash
while true; do 
    echo "Hello World" # Substitute this line for whatever command you want.
    sleep 100
done

Then run it by typing bash ./while_check.sh &

You can use projections from Spring Data JPA (doc). In your case, create interface:

interface ProjectIdAndName{
    String getId();
    String getName();
}

and add following method to your repository

List<ProjectIdAndName> findAll();

You can't use ^ and $ in character classes in the way you wish - they will be interpreted literally, but you can use an alternation to achieve the same effect:

(^|,)garp(,|$)

To reset your keyring.

1. Go into your home folder.

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

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

4. Find the default.keyring file.

5. Move that file to a different folder.

6. Once done, reboot your computer.

You can use 2 methods:

Method 1

<div [ngStyle]="{'background-image': 'url(&quot;' + photo + '&quot;)'}"></div>

Method 2

<div [style.background-image]="'url(&quot;' + photo + '&quot;)'"></div>

Note: it is important to surround the URL with " char.

I use iterator and a while loop to store the various window handles and then switch back and forth.

//Click your link
driver.findElement(By.xpath("xpath")).click();
//Get all the window handles in a set
Set <String> handles =driver.getWindowHandles();
Iterator<String> it = handles.iterator();
//iterate through your windows
while (it.hasNext()){
String parent = it.next();
String newwin = it.next();
driver.switchTo().window(newwin);
//perform actions on new window
driver.close();
driver.switchTo().window(parent);
            }

SQL FULL OUTER JOIN

• The FULL OUTER JOIN returns all rows from the left table (table1) and from the right table (table2) irrespective of the match.

• The FULL OUTER JOIN keyword combines the result of both LEFT OUTER JOIN and RIGHT OUTER JOIN

• SQL full outer join is also known as FULL JOIN

Reference : http://datasciencemadesimple.com/sql-full-outer-join/

SQL CROSS JOIN

• In SQL CROSS JOIN Each Row of first table is mapped with the each and every row of second table.

• Number of rows produced by a result set of CROSS JOIN operation is equal to number of rows in the first table multiplied by the number of rows in the second table.

• CROSS JOIN is also known as Cartesian product / Cartesian join

• Number of rows in table A is m, Number of rows in table B is n and resultant table will have m*n rows

Here's the easy way to get access to the web.config settings anywhere in your C# project.

 Properties.Settings.Default

Use case:

litBodyText.Text = Properties.Settings.Default.BodyText;
litFootText.Text = Properties.Settings.Default.FooterText;
litHeadText.Text = Properties.Settings.Default.HeaderText;

Web.config file:

  <applicationSettings>
    <myWebSite.Properties.Settings> 
      <setting name="BodyText" serializeAs="String">
        <value>
          &lt;h1&gt;Hello World&lt;/h1&gt;
          &lt;p&gt;
      Ipsum Lorem
          &lt;/p&gt;
        </value>
      </setting>
      <setting name="HeaderText" serializeAs="String">
      My header text
        <value />
      </setting>
      <setting name="FooterText" serializeAs="String">
      My footer text
        <value />
      </setting>
    </myWebSite.Properties.Settings>
  </applicationSettings>

No need for special routines - everything is right there already. I'm surprised that no one has this answer for the best way to read settings from your web.config file.

The easiest way is to use lubridate:

library(lubridate)
prods.all$Date2 <- mdy(prods.all$Date2)

This function automatically returns objects of class POSIXct and will work with either factors or characters.

An example:

log4j.rootLogger=ERROR, logfile

log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.datePattern='-'dd'.log'
log4j.appender.logfile.File=log/radius-prod.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

log4j.logger.foo.bar.Baz=DEBUG, myappender
log4j.additivity.foo.bar.Baz=false

log4j.appender.myappender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myappender.datePattern='-'dd'.log'
log4j.appender.myappender.File=log/access-ext-dmz-prod.log
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

I don't believe you can do this with an accordion since it's specifically designed preserve the property that at most one item will be opened. However, even though you say you don't want to re-implement accordion, you might be over estimating the complexity involved.

Consider the following scenario where you have a vertical stack of elements,

++++++++++++++++++++
+     Header 1     +
++++++++++++++++++++
+                  +
+      Item 1      +
+                  +
++++++++++++++++++++
+     Header 2     +
++++++++++++++++++++
+                  +
+      Item 2      +
+                  +
++++++++++++++++++++

If you're lazy you could build this using a table, otherwise, suitably styled DIVs will also work.

Each of the item blocks can have a class of itemBlock. Clicking on a header will cause all elements of class itemBlock to be hidden ($(".itemBlock").hide()). You can then use the jquery slideDown() function to expand the item below the header. Now you've pretty much implemented accordion.

To expand all items, just use $(".itemBlock").show() or if you want it animated, $(".itemBlock").slideDown(500). To hide all items, just use $(".itemBlock").hide().

Another answer here also mentions since 2012 you can remove Remove cached login via How to remove cached server names from the Connect to Server dialog?. Just confirmed this delete in MRU list works fine in 2016 and 2017.

SQL Server Management Studio 2017 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\14.0\SqlStudio.bin

SQL Server Management Studio 2016 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\13.0\SqlStudio.bin

SQL Server Management Studio 2014 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\12.0\SqlStudio.bin

SQL Server Management Studio 2012 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\11.0\SqlStudio.bin

SQL Server Management Studio 2008 delete the file C:\Users\%username%\AppData\Roaming\Microsoft\Microsoft SQL Server\100\Tools\Shell\SqlStudio.bin

SQL Server Management Studio 2005 delete the file – same as above answer but the Vista path. C:\Users\%username%\AppData\Roaming\Microsoft\Microsoft SQL Server\90\Tools\Shell\mru.dat

These are profile paths for Vista / 7 / 8.

EDIT:

Note, AppData is a hidden folder. You need to show hidden folders in explorer.

EDIT: You can simply press delete from the Server / User name drop down (confirmed to be working for SSMS v18.0). Original source from https://blog.sqlauthority.com/2013/04/17/sql-server-remove-cached-login-from-ssms-connect-dialog-sql-in-sixty-seconds-049/ which mentioned that this feature is available since 2012!

On Windows, if the debug.keystore file is not in the location (C:\Users\username\.android), the debug.keystore file may also be found in the location where you have installed Android Studio.

As no answer is accepted and people (like I did) land here I give my variation. Though I am not sure that was the original problem. When the navigation controller is added as a subview to a another view you must call the viewWillAppear/Dissappear etc. methods yourself like this:

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    [subNavCntlr viewWillAppear:animated];
}

- (void) viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    [subNavCntlr viewWillDisappear:animated];
}

Just to make the example complete. This code appears in my ViewController where I created and added the the navigation controller into a view that I placed on the view.

- (void)viewDidLoad {

    // This is the root View Controller
    rootTable *rootTableController = [[rootTable alloc]
                 initWithStyle:UITableViewStyleGrouped];

    subNavCntlr = [[UINavigationController alloc]   
                  initWithRootViewController:rootTableController];

    [rootTableController release];

    subNavCntlr.view.frame = subNavContainer.bounds;

    [subNavContainer addSubview:subNavCntlr.view];

    [super viewDidLoad];
}

the .h looks like this

@interface navTestViewController : UIViewController <UINavigationControllerDelegate> {
    IBOutlet UIView *subNavContainer;
    UINavigationController *subNavCntlr;
}

@end

In the nib file I have the view and below this view I have a label a image and the container (another view) where i put the controller in. Here is how it looks. I had to scramble some things as this was work for a client.

Fixed with downgrading Node from v12.8.1 to v11.15.0 and everything installed successfully

Sorry for being so late at the party, but I see some room for improvement here. Not concerning "disable textbox", but to the radionbox selection and code simplification, making it a bit more future proof, for later changes.

First of all, you shouldn't use .each() and use the index to point out a specific radio button. If you work with a dynamic set of radio buttons or if you add or remove some radio buttons afterwards, then your code will react on the wrong button!

Next, but that wasn't probably the case when the OP was made, I prefer to use .on('click', function(){...}) instead of click... http://api.jquery.com/on/

Lst but not least, also the code could be made more simple and future proof by selecting the radio button based on it's name (but that appeared already in a post).

So I ended up with the following code.

HTML (based on code of o.k.w)

<span id="radiobutt">
    <input type="radio" name="rad1" value="1" />
    <input type="radio" name="rad1" value="2" />
    <input type="radio" name="rad1" value="3" />
</span>
<div>
    <input type="text" id="textbox1" />
    <input type="checkbox" id="checkbox1" />
</div>

JS-code

$("[name='rad1']").on('click', function() {
    var disable = $(this).val() === "2";
    $("#textbox1").prop("disabled", disable); 
    $("#checkbox1").prop("disabled", disable); 
});

For concatenating selectors together when nesting, you need to use the parent selector (&):

.class {
    margin:20px;
    &:hover {
        color:yellow;
    }
}

<?php
// Example API call
$data = array(array (
    "REGION" => "MUMBAI",
    "LOCATION" => "NA",
    "STORE" => "AMAZON"));
// json encode data
$authToken = "xxxxxxxxxx";
$data_string = json_encode($data); 
// set up the curl resource
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://domainyouhaveapi.com");   
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'Content-Type:application/json',       
    'Content-Length: ' . strlen($data_string) ,
    'API-TOKEN-KEY:'.$authToken ));   // API-TOKEN-KEY is keyword so change according to ur key word. like authorization 
// execute the request
$output = curl_exec($ch);
//echo $output;
// Check for errors
if($output === FALSE){
    die(curl_error($ch));
}
echo($output) . PHP_EOL;
// close curl resource to free up system resources
curl_close($ch);

Should be

<input type="button" class="btn btn-success"
                       style="font-weight: bold;display: inline;"
                       value="Close"
                       onclick="closeMe()">
<script>
function closeMe()
{
    window.opener = self;
    window.close();
}
</script>

If any other solution is in the debug mode then first stop them all and after that restart the visual studio. It worked for me.

I have created a heap wrapper that inverts the values to create a max-heap, as well as a wrapper class for a min-heap to make the library more OOP-like. Here is the gist. There are three classes; Heap (abstract class), HeapMin, and HeapMax.

Methods:

isempty() -> bool; obvious
getroot() -> int; returns min/max
push() -> None; equivalent to heapq.heappush
pop() -> int; equivalent to heapq.heappop
view_min()/view_max() -> int; alias for getroot()
pushpop() -> int; equivalent to heapq.pushpop

Big warning on several of the solutions (and your own test) :

When you do : anything | xargs something

xargs will try to fit "as many arguments as possible" after "something", but then you may end up with multiple invocations of "something".

So your attempt: find ... | xargs tar czvf file.tgz may end up overwriting "file.tgz" at each invocation of "tar" by xargs, and you end up with only the last invocation! (the chosen solution uses a GNU -T special parameter to avoid the problem, but not everyone has that GNU tar available)

You could do instead:

find . -type f -print0 | xargs -0 tar -rvf backup.tar
gzip backup.tar

Proof of the problem on cygwin:

$ mkdir test
$ cd test
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs touch 
    # create the files
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar czvf archive.tgz
    # will invoke tar several time as it can'f fit 10000 long filenames into 1
$ tar tzvf archive.tgz | wc -l
60
    # in my own machine, I end up with only the 60 last filenames, 
    # as the last invocation of tar by xargs overwrote the previous one(s)

# proper way to invoke tar: with -r  (which append to an existing tar file, whereas c would overwrite it)
# caveat: you can't have it compressed (you can't add to a compressed archive)
$ seq 1 10000 | sed -e "s/^/long_filename_/" | xargs tar rvf archive.tar #-r, and without z
$ gzip archive.tar
$ tar tzvf archive.tar.gz | wc -l
10000 
  # we have all our files, despite xargs making several invocations of the tar command

 

Note: that behavior of xargs is a well know diccifulty, and it is also why, when someone wants to do :

find .... | xargs grep "regex"

they intead have to write it:

find ..... | xargs grep "regex" /dev/null

That way, even if the last invocation of grep by xargs appends only 1 filename, grep sees at least 2 filenames (as each time it has: /dev/null, where it won't find anything, and the filename(s) appended by xargs after it) and thus will always display the file names when something maches "regex". Otherwise you may end up with the last results showing matches without a filename in front.

If you're just needing to export to excel, you can use the export data wizard. Right click the database, Tasks->Export data.

There is no concept of folders or directories in S3. You can create file names like "abc/xys/uvw/123.jpg", which many S3 access tools like S3Fox show like a directory structure, but it's actually just a single file in a bucket.

Use This code

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>
void main(){
char a[10];
clrscr();
gets(a);
int i,length=0;
for(i=0;a[i]!='\0';i++)
length+=1;
for(i=0;i<length;i++){
a[i]=a[i]^32;
}
printf("%s",&a);
getch();
}

It can be easily done using html2canvas, try out the following,

try adding the div inside a html modal and call the model id using a jquery function. In the function you can specify the size (height, width) of the image to be displayed. Using modal is an easy way to capture a html div into an image in a button onclick.

for example have a look at the code sample,

`

        <!-- Modal content-->
        <div class="modal-content">
            <div class="modal-header">


            <div class="modal-body">
                <p>Some text in the modal.</p>

`

paste the div, which you want to be displayed, inside the model. Hope it will help.

You should use the EndXXX of your async method to return the value. EndXXX should wait until there is a result using the IAsyncResult's WaitHandle and than return with the value.

cygwin is another option. It has a port of svn.

To add on to Evan Fossmark's answer, here's an example of how to use filelock:

from filelock import FileLock

lockfile = r"c:\scr.txt"
lock = FileLock(lockfile + ".lock")
with lock:
    file = open(path, "w")
    file.write("123")
    file.close()

Any code within the with lock: block is thread-safe, meaning that it will be finished before another process has access to the file.

You cant simply (directly) convert the datareader to list.

You have to loop through all the elements in datareader and insert into list

below the sample code

using (drOutput)   
{
            System.Collections.Generic.List<CustomerEntity > arrObjects = new System.Collections.Generic.List<CustomerEntity >();        
            int customerId = drOutput.GetOrdinal("customerId ");
            int CustomerName = drOutput.GetOrdinal("CustomerName ");

        while (drOutput.Read())        
        {
            CustomerEntity obj=new CustomerEntity ();
            obj.customerId = (drOutput[customerId ] != Convert.DBNull) ? drOutput[customerId ].ToString() : null;
            obj.CustomerName = (drOutput[CustomerName ] != Convert.DBNull) ? drOutput[CustomerName ].ToString() : null;
            arrObjects .Add(obj);
        }

}

Thanks to @Eswar. This code worked perfectly for me. I want to add certain things to the solution :

I was getting error : java.io.IOException: RESTEASY007550: Unable to get boundary for multipart

In order to solve this error, you should remove the "Content-Type" "multipart/form-data". It solved my problem.

I also faced the same problem. I updated my .edmx from the database after that the exception has vanished.

Documentation here, and I'll use the Frankfurt region as an example.

There are 2 different URL styles:

• Virtual host style: https://BUCKET.s3.amazonaws.com/FILE
• Path style: https://s3.eu-central-1.amazonaws.com/BUCKET/FILE

But this url does not work:

• https://s3.amazonaws.com/BUCKET/FILE

The message is explicit: The bucket you are attempting to access must be addressed using the specified endpoint. Please send all future requests to this endpoint.

I may be talking about another problem because I'm not getting NoSuchKey error but I suspect the error message has been made clearer over time.

1) Using Terminal (On Linux), go to the apache-tomcat-directory/bin folder.

2) Type ./catalina.sh start

3) To stop Tomcat, type ./catalina.sh stop from the bin folder. For some reason ./startup.sh doesn't work sometimes.

I had the same issue today when running the ancient software Dundjinni, a mapping tool, on Windows 10. (Dundjinni requires a rather old installation of Java; I haven’t tried updating Java, for fear the programme will fail.) My method was to simply run Dundjinni in administrator mode. Here is how:

Click Start or press the Start key, navigate down to the software, rightclick the programme, choose More, then choose Run as administrator. Note that this option is not available if you simply type the name of the software.

One interesting fact about the obj directory: If you have publishing set up in a web project, the files that will be published are staged to obj\Release\Package\PackageTmp. If you want to publish the files yourself rather than use the integrated VS feature, you can grab the files that you actually need to deploy here, rather than pick through all the digital debris in the bin directory.

You don't need the assignment, list.append(x) will always append x to a and therefore there's no need te redefine a.

a = []
for i in range(5):    
    a.append(i)
print(a)

is all you need. This works because lists are mutable.

Also see the docs on data structures.

As others have said, there is no way to do a single line comment legally in XML that comments out multiple lines, but, there are ways to make commenting out segments of XML easier.

Looking at the example below, if you add '>' to line one, the XmlTag will be uncommented. Remove the '>' and it's commented out again. This is the simplest way that I've seen to quickly comment/uncomment XML without breaking things.

<!-- --
<XmlTag variable="0" />
<!-- -->

The added benefit is that you only manipulate the top comment, and the bottom comment can just sit there forever. This breaks compatibility with SGML and some XML parsers will barf on it. So long as this isn't a permanent fixture in your XML, and your parsers accept it, it's not really a problem.

Stack Overflow's and Notepad++'s syntax highlighter treat it like a multi-line comment, C++'s Boost library treats it as a multi-line comment, and the only parser I've found so far that breaks is the one in .NET, specifically C#. So, be sure to first test that your tools, IDE, libraries, language, etc. accept it before using it.

If you care about SGML compatibility, simply use this instead:

<!-- -
<XmlTag variable="0" />
<!- -->

Add '->' to the top comment and a '-' to the bottom comment. The downside is having to edit the bottom comment each time, which would probably make it easier to just type in <!-- at the top and --> at the bottom each time.

I also want to mention that other commenters recommend using an XML editor that allows you to right-click and comment/uncomment blocks of XML, which is probably preferable over fancy find/replace tricks (it would also make for a good answer in itself, but I've never used such tools. I just want to make sure the information isn't lost over time). I've personally never had to deal with XML enough to justify having an editor fancier than Notepad++, so this is totally up to you.

.html always for new files. .htm is a throwback to dos days.

what about a one-liner using String.split()?

String s = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
String[] split = s.split( "(?<!\".{0,255}[^\"]),|,(?![^\"].*\")" );

I´ve used this:

String currentLanguage = Locale.getDefault().getDisplayLanguage();
if (currentLanguage.toLowerCase().contains("en")) {
   //do something
}

None of the above worked for me. Finally it wasn't anything related to any configuration.

I was getting the 404 error while trying to run a debug session through Visual Studio 2017 using the built in IISExpress 10.0. For me it was working when the release was published to the IIS server but getting a 404 when debugging locally through VS.

The issue turned out to be some old compiled files lying in the project bin directory which appeared to be interfering. Finally did a "Clean solution", closed VS, deleted the bin and obj folder. Restarted VS and rebuild project and the error went away.

@freelancer If you are using ScriptManager then try this code for message..

string script = "alert(\"Hello!\");";
ScriptManager.RegisterStartupScript(this, GetType(), 
                      "ServerControlScript", script, true);

Adding to what @Shog9 posted, you can also restrict dates individually in the beforeShowDay: callback function.

You supply a function that takes a date and returns a boolean array:

"$(".selector").datepicker({ beforeShowDay: nationalDays}) 
natDays = [[1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'], [4, 27, 'za'], 
[5, 25, 'ar'], [6, 6, 'se'], [7, 4, 'us'], [8, 17, 'id'], [9, 7, 
'br'], [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']]; 
function nationalDays(date) { 
    for (i = 0; i < natDays.length; i++) { 
      if (date.getMonth() == natDays[i][0] - 1 && date.getDate() == 
natDays[i][1]) { 
        return [false, natDays[i][2] + '_day']; 
      } 
    } 
  return [true, '']; 
} 

I assume you are talking about real push notifications that can be delivered even when the user is not surfing your website (otherwise check out WebSockets or legacy methods like long polling).

Can we use GCM/APNS to send push notification to all Web Browsers including Firefox & Safari?

GCM is only for Chrome and APNs is only for Safari. Each browser manufacturer offers its own service.

If not via GCM can we have our own back-end to do the same?

The Push API requires two backends! One is offered by the browser manufacturer and is responsible for delivering the notification to the device. The other one should be yours (or you can use a third party service like Pushpad) and is responsible for triggering the notification and contacting the browser manufacturer's service (i.e. GCM, APNs, Mozilla push servers).

I'm using this in Python to get a single file:

df.toPandas().to_csv("/tmp/my.csv", sep=',', header=True, index=False)

I'm surprised no one offered this answer. It's not as "built-in" as Ruby's ||= but it's basically equivalent and still a one-liner:

foo = foo if 'foo' in locals() else 'default'

Of course, locals() is just a dictionary, so you can do:

foo = locals().get('foo', 'default')

I got same problem. So I looked into the axios document. I found it. you can do it like this. this is easiest way. and super simple.

https://www.npmjs.com/package/axios#using-applicationx-www-form-urlencoded-format

var params = new URLSearchParams();
params.append('param1', 'value1');
params.append('param2', 'value2');
axios.post('/foo', params);

You can use .then,.catch.

Swift 2:

As OP asked, only adjust the size, not setting it as a system bold font or whatever:

func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        if let headerView = view as? UITableViewHeaderFooterView, textLabel = headerView.textLabel {

            let newSize = CGFloat(16)
            let fontName = textLabel.font.fontName
            textLabel.font = UIFont(name: fontName, size: newSize)
        }
    }

It looks like window.open will take a Data URI as the location parameter.

So you can open it like this from the question: Opening PDF String in new window with javascript:

window.open("data:application/pdf;base64, " + base64EncodedPDF);

Here's an runnable example in plunker, and sample pdf file that's already base64 encoded.

Then on the server, you can convert the byte array to base64 encoding like this:

string fileName = @"C:\TEMP\TEST.pdf";
byte[] pdfByteArray = System.IO.File.ReadAllBytes(fileName);
string base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);

NOTE: This seems difficult to implement in IE because the URL length is prohibitively small for sending an entire PDF.

Why not rewrite it to be

for element in somelist: 
   do_action(element)  

if check(element): 
    remove_element_from_list

See this question for how to remove from the list, though it looks like you've already seen that Remove items from a list while iterating

Another option is to do this if you really want to keep this the same

newlist = [] 
for element in somelist: 
   do_action(element)  

   if not check(element): 
      newlst.append(element)

For whole html document try this

html * {cursor:none}

Or if some css overwrite your cursor: none use !important

html * {cursor:none!important}

It's additional information, and isn't an answer.

In C++11 you can write:

for (auto& it : s) {
    cout << it << endl;
}

instead of

for (auto it = s.begin(); it != s.end(); it++) {
    cout << *it << endl;
}

It has the same meaning.

Update: See the @Alnitak's comment also.

Please use Google API console
Create a new project
For the created project goto API access
There you will find your Client ID and Secret. And the API key in the last is your developer key.

I strongly favour minimal file headers, by which I mean just:

• The hashbang (#! line) if this is an executable script
• Module docstring
• Imports, grouped in the standard way, eg:

  import os    # standard library
  import sys

  import requests  # 3rd party packages

  from mypackage import (  # local source
      mymodule,
      myothermodule,
  )

ie. three groups of imports, with a single blank line between them. Within each group, imports are sorted. The final group, imports from local source, can either be absolute imports as shown, or explicit relative imports.

Everything else is a waste of time, visual space, and is actively misleading.

If you have legal disclaimers or licencing info, it goes into a separate file. It does not need to infect every source code file. Your copyright should be part of this. People should be able to find it in your LICENSE file, not random source code.

Metadata such as authorship and dates is already maintained by your source control. There is no need to add a less-detailed, erroneous, and out-of-date version of the same info in the file itself.

I don't believe there is any other data that everyone needs to put into all their source files. You may have some particular requirement to do so, but such things apply, by definition, only to you. They have no place in “general headers recommended for everyone”.

code:

class Main
{
    public static void main(String[] args)  
    {
        int a=10, b=20;
        System.out.println(a + " " + b);
    }
}

Input: none

Output: 10 20

If you looking for some command in CLI, Then ans is NO for now. But you can do manually by deleting the component folder and all the references.

Most answers are surprisingly complicated or erroneous. However simple and robust examples have been posted elsewhere [codereview]. Admittedly the options provided by the gnu preprocessor are a bit confusing. However, the removal of all directories from the build target with -MM is documented and not a bug [gpp]:

By default CPP takes the name of the main input file, deletes any directory components and any file suffix such as ‘.c’, and appends the platform's usual object suffix.

The (somewhat newer) -MMD option is probably what you want. For completeness an example of a makefile that supports multiple src dirs and build dirs with some comments. For a simple version without build dirs see [codereview].

CXX = clang++
CXX_FLAGS = -Wfatal-errors -Wall -Wextra -Wpedantic -Wconversion -Wshadow

# Final binary
BIN = mybin
# Put all auto generated stuff to this build dir.
BUILD_DIR = ./build

# List of all .cpp source files.
CPP = main.cpp $(wildcard dir1/*.cpp) $(wildcard dir2/*.cpp)

# All .o files go to build dir.
OBJ = $(CPP:%.cpp=$(BUILD_DIR)/%.o)
# Gcc/Clang will create these .d files containing dependencies.
DEP = $(OBJ:%.o=%.d)

# Default target named after the binary.
$(BIN) : $(BUILD_DIR)/$(BIN)

# Actual target of the binary - depends on all .o files.
$(BUILD_DIR)/$(BIN) : $(OBJ)
    # Create build directories - same structure as sources.
    mkdir -p $(@D)
    # Just link all the object files.
    $(CXX) $(CXX_FLAGS) $^ -o $@

# Include all .d files
-include $(DEP)

# Build target for every single object file.
# The potential dependency on header files is covered
# by calling `-include $(DEP)`.
$(BUILD_DIR)/%.o : %.cpp
    mkdir -p $(@D)
    # The -MMD flags additionaly creates a .d file with
    # the same name as the .o file.
    $(CXX) $(CXX_FLAGS) -MMD -c $< -o $@

.PHONY : clean
clean :
    # This should remove all generated files.
    -rm $(BUILD_DIR)/$(BIN) $(OBJ) $(DEP)

This method works because if there are multiple dependency lines for a single target, the dependencies are simply joined, e.g.:

a.o: a.h
a.o: a.c
    ./cmd

is equivalent to:

a.o: a.c a.h
    ./cmd

as mentioned at: Makefile multiple dependency lines for a single target?

Typically, a Json object would contain your values (including arrays) as named fields within. So, something like:

JSONObject jo = new JSONObject();
JSONArray ja = new JSONArray();
// populate the array
jo.put("arrayName",ja);

Which in JSON will be {"arrayName":[...]}.

If you are using Android Studio 3.0 or above make sure your project build.gradle should have content similar to-

buildscript {                 
    repositories {
        google()
        jcenter()
    }
    dependencies {            
        classpath 'com.android.tools.build:gradle:3.0.1'

    }
}

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

Note- position really matters add google() before jcenter()

And for below Android Studio 3.0 and starting from support libraries 26.+ your project build.gradle must look like this-

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

The code above exports data without the heading columns which is weird. Here's how to do it. You have to merge the two files later though using text a editor.

SELECT column_name FROM information_schema.columns WHERE table_schema = 'my_app_db' AND table_name = 'customers' INTO OUTFILE 'C:/ProgramData/MySQL/MySQL Server 5.6/Uploads/customers_heading_cols.csv' FIELDS TERMINATED BY '' OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY ',';

As everyone else told you, you can convert it directly... UNLESS you meant something like "how can I convert an ASCII Extended character to its UTF-16 or UTF-32 value". This is a TOTALLY different question (one at least as good). And one quite difficult, if I remember correctly, if you are using only "pure" C. Then you could start here: https://stackoverflow.com/questions/114611/what-is-the-best-unicode-library-for-c/114643#114643

(for ASCII Extended I mean one of the many "extensions" to the ASCII set. The 0-127 characters of the base ASCII set are directly convertible to Unicode, while the 128-255 are not.). For example ISO_8859-1 http://en.wikipedia.org/wiki/ISO_8859-1 is an 8 bit extensions to the 7 bit ASCII set, or the (quite famous) codepages 437 and 850.

This another helpful code:

"2011-05-19 10:30:14".to_datetime.strftime('%a %b %d %H:%M:%S %Z %Y')

Use below command on UNIX terminal :

java -XshowSettings

This will display all java properties and system settings. In this look for java.io.tmpdir value.

If you want to control the formatting of the unique identifier you can create your own <FieldType> in SharePoint. MSDN also has a visual How-To. This basically means that you're creating a custom column.

WSS defines the Counter field type (which is what the ID column above is using). I've never had the need to re-use this or extend it, but it should be possible.

A solution might exist without creating a custom <FieldType>. For example: if you wanted unique IDs like CUST1, CUST2, ... it might be possible to create a Calculated column and use the value of the ID column in you formula (="CUST" & [ID]). I haven't tried this, but this should work :)

<div class="row">
    <div class="col-lg-3">
       <div class="affix">
           fixed position 
        </div>
    </div>
    <div class="col-lg-9">
       Normal data enter code here
    </div>
</div>

Here is a simple method to create delegates

Create Protocol in .h file. Make sure that is defined before the protocol using @class followed by the name of the UIViewController < As the protocol I am going to use is UIViewController class>.

Step : 1 : Create a new class Protocol named "YourViewController" which will be the subclass of UIViewController class and assign this class to the second ViewController.

Step : 2 : Go to the "YourViewController" file and modify it as below:

#import <UIKit/UIkit.h>
@class YourViewController;

@protocol YourViewController Delegate <NSObject>

 @optional
-(void)defineDelegateMethodName: (YourViewController *) controller;

@required
-(BOOL)delegateMethodReturningBool: (YourViewController *) controller;

  @end
  @interface YourViewController : UIViewController

  //Since the property for the protocol could be of any class, then it will be marked as a type of id.

  @property (nonatomic, weak) id< YourViewController Delegate> delegate;

@end

The methods defined in the protocol behavior can be controlled with @optional and @required as part of the protocol definition.

Step : 3 : Implementation of Delegate

    #import "delegate.h"

   @interface YourDelegateUser ()
     <YourViewControllerDelegate>
   @end

   @implementation YourDelegateUser

   - (void) variousFoo {
      YourViewController *controller = [[YourViewController alloc] init];
      controller.delegate = self;
   }

   -(void)defineDelegateMethodName: (YourViewController *) controller {
      // handle the delegate being called here
   }

   -(BOOL)delegateMethodReturningBool: (YourViewController *) controller {
      // handle the delegate being called here
      return YES;
   }

   @end

//test whether the method has been defined before you call it

 - (void) someMethodToCallDelegate {
     if ([[self delegate] respondsToSelector:@selector(defineDelegateMethodName:)]) {
           [self.delegate delegateMethodName:self]; 
     }
  }

You should not rely on a hard coded build dir name in your script, so the line with ../Compile must be changed.

It's because it should be up to user where to compile.

Instead of that use one of predefined variables: http://www.cmake.org/Wiki/CMake_Useful_Variables (look for CMAKE_BINARY_DIR and CMAKE_CURRENT_BINARY_DIR)

After trying @Philipp Claßen steps, even if did not work then,

Change eclipse, workspace and tomcat directory. [tested only for Windows7]

I know somebody might say that is not correct, but that did work for me after @Phillipp's steps not worked for me.

It took me 4 hours to find this brute force method solution.

Simply Use:

String Uri = request.getRequestURL()+"?"+request.getQueryString();

If you are using Table.query property:

from sqlalchemy import func
Table.query.with_entities(Table.column, func.count(Table.column)).group_by(Table.column).all()

If you are using session.query() method (as stated in miniwark's answer):

from sqlalchemy import func
session.query(Table.column, func.count(Table.column)).group_by(Table.column).all()

The OPTIONS is from http://www.w3.org/TR/cors/ See http://metajack.im/2010/01/19/crossdomain-ajax-for-xmpp-http-binding-made-easy/ for a bit more info

I found three different ways here: http://www.rgagnon.com/javadetails/java-0596.html

The most elegant one, as he also notes, I think is this one:

static final String HEXES = "0123456789ABCDEF";
public static String getHex( byte [] raw ) {
    if ( raw == null ) {
        return null;
    }
    final StringBuilder hex = new StringBuilder( 2 * raw.length );
    for ( final byte b : raw ) {
        hex.append(HEXES.charAt((b & 0xF0) >> 4))
            .append(HEXES.charAt((b & 0x0F)));
    }
    return hex.toString();
}

I know your question does not specify if you are trying to open all a tags in a new window or only the external links.

But in case you only want external links to open in a new tab you can do this:

$( 'a[href^="http://"]' ).attr( 'target','_blank' )
$( 'a[href^="https://"]' ).attr( 'target','_blank' )

The Integer is immutable. You can wrap int in your custom wrapper class.

class WrapInt{
    int value;
}

WrapInt theInt = new WrapInt();

inc(theInt);
System.out.println("main: "+theInt.value);

Something like this:

select 
  * 
from sales 
where salesDate >= '11/11/2010' 
  AND salesDate < (Convert(datetime, '11/11/2010') + 1)

Answer using TypeScript spread operator (...)

// Your key
const key = 'two';

// Your array
const arr = [
    'one',
    'two',
    'three'
];

// Get either the index or -1
const index = arr.indexOf(key); // returns 0


// Despite a real index, or -1, use spread operator and Array.prototype.slice()    
const newArray = (index > -1) ? [
    ...arr.slice(0, index),
    ...arr.slice(index + 1)
] : arr;

This worked for me in Luna elementary OS

sudo apt-get install libxtst6:i386

There is a new player in the field, offering advanced Navigation Charts that are using Canvas for super-smooth animations and performance:

https://zoomcharts.com/

Example of charts:

Documentation: https://zoomcharts.com/en/javascript-charts-library/charts-packages/pie-chart/

What is cool about this lib:

• Others slice can be expanded
• Pie offers drill down for hierarchical structures (see example)
• write your own data source controller easily, or provide simple json file
• export high res images out of box
• full touch support, works smoothly on iPad, iPhone, android, etc.

Charts are free for non-commercial use, commercial licenses and technical support available as well.

Also interactive Time charts and Net Charts are there for you to use.

Charts come with extensive API and Settings, so you can control every aspect of the charts.

You cannot attach events before the elements you attach them to has loaded

This works -

Plain JS

DEMO

Recommended to use eventListener

// Should only be triggered on first page load
console.log('ho');

window.addEventListener("load", function() {
  document.getElementById('my-form').addEventListener("submit", function(e) {
    e.preventDefault(); // before the code
    /* do what you want with the form */

    // Should be triggered on form submit
    console.log('hi');
  })
});

<form id="my-form">
  <input type="text" name="in" value="some data" />
  <button type="submit">Go</button>
</form>

but if you do not need more than one listener you can use onload and onsubmit

// Should only be triggered on first page load
console.log('ho');

window.onload = function() {
  document.getElementById('my-form').onsubmit = function() {
    /* do what you want with the form */

    // Should be triggered on form submit
    console.log('hi');
    // You must return false to prevent the default form behavior
    return false;
  }
}

    <form id="my-form">
      <input type="text" name="in" value="some data" />
      <button type="submit">Go</button>
    </form>

jQuery

// Should only be triggered on first page load
console.log('ho');

$(function() {
  $('#my-form').on("submit", function(e) {
    e.preventDefault(); // cancel the actual submit

    /* do what you want with the form */

    // Should be triggered on form submit

    console.log('hi');
  });
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form id="my-form">
  <input type="text" name="in" value="some data" />
  <button type="submit">Go</button>
</form>

This works:

async function IsLoggedIn(): Promise<boolean> {
  try {
    await new Promise((resolve, reject) =>
      app.auth().onAuthStateChanged(
        user => {
          if (user) {
            // User is signed in.
            resolve(user)
          } else {
            // No user is signed in.
            reject('no user logged in')
          }
        },
        // Prevent console error
        error => reject(error)
      )
    )
    return true
  } catch (error) {
    return false
  }
}

They both do the same thing (unless someone's done something unusual), other than that your second one creates an object and adds a property to it. But literal notation takes less space in the source code. It's clearly recognizable as to what is happening, so using new Object(), you are really just typing more and (in theory, if not optimized out by the JavaScript engine) doing an unnecessary function call.

These

person = new Object() /*You should put a semicolon here too.  
It's not required, but it is good practice.*/ 
-or-

person = {
    property1 : "Hello"
};

technically do not do the same thing. The first just creates an object. The second creates one and assigns a property. For the first one to be the same you then need a second step to create and assign the property.

The "something unusual" that someone could do would be to shadow or assign to the default Object global:

// Don't do this
Object = 23;

In that highly-unusual case, new Object will fail but {} will work.

In practice, there's never a reason to use new Object rather than {} (unless you've done that very unusual thing).

SQL Statement:

 SELECT * FROM employee WHERE employeeName LIKE 'A%';

Result:

Number of Records: 4

employeeID  employeeName    employeeName    Address City    PostalCode  Country

1           Alam             Wipro          Delhi   Delhi   11005      India

2           Aditya           Wipro          Delhi   Delhi   11005      India

3           Alok             HCL            Delhi   Delhi   11005      India

4           Ashok            IBM            Delhi   Delhi   11005      India

These two are quite different:

Default methods are to add external functionality to existing classes without changing their state.

And abstract classes are a normal type of inheritance, they are normal classes which are intended to be extended.

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

You could use LastIndexOf and Substring combined to get all characters to the left of the last index of the comma within the sting.

string var = var.Substring(0, var.LastIndexOf(','));

Just in case you actually mean discard changes whenever you use git stash (and don't really use git stash to stash it temporarily), in that case you can use

git checkout -- <file>

[NOTE]

That git stash is just a quicker and simple alternative to branching and doing stuff.

Just like someone above said you can send it as a string parameter but it must have this format: '20130121' for example and you can convert it to that format taking it directly from the control. So you'll get it for example from a textbox like:

date = datetextbox.text; // date is going to be something like: "2013-01-21 12:00:00am"

to convert it to: '20130121' you use:

date = date.Substring(6, 4) + date.Substring(3, 2) + date.Substring(0, 2);

so that SQL can convert it and put it into your database.

Also, look at your perfmon counters. They can tell you where a lot of that cpu time is being spent. Here's a link to the most common counters to use:

• http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/852720c8-7589-49c3-a9d1-73fdfc9126f0.mspx?mfr=true
• http://www.microsoft.com/technet/prodtechnol/WindowsServer2003/Library/IIS/be425785-c1a4-432c-837c-a03345f3885e.mspx?mfr=true

1. Open your PHP folder.
2. Find php.ini-development and open it.
3. Find ;extension=mysqli
4. delete the ; symbol
5. save file and change the file extension from php.ini-development to php.ini
6. Restart the server and test the code:

    if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) {  
            echo 'We don\'t have mysqli!!!';  
     } else {  
         echo 'mysqli is installed';
     }

7. if it not working, change both extension_dir in php.ini from "ext" to "c:\php\ext" and extension=mysqli to extension=php_mysqli.dll then test again Remember to reset the server every time you test

The short answer is no. The long answer is yes. :-)

Markdown was designed to allow people to write simple, readable text that could be easily converted to a simple HTML markup. It doesn't really do document layout. For example, there's no real way to align an image to the right or left. As to your question, there's no markdown command to include a single link from one file to another in any version of markdown (so far as I know).

The closest you could come to this functionality is Pandoc. Pandoc allows you to merge files as a part of the transformation, which allows you to easily render multiple files into a single output. For example, if you were creating a book, then you could have chapters like this:

01_preface.md
02_introduction.md
03_why_markdown_is_useful.md
04_limitations_of_markdown.md
05_conclusions.md

You can merge them by doing executing this command within the same directory:

pandoc *.md > markdown_book.html

Since pandoc will merge all the files prior to doing the translation, you can include your links in the last file like this:

01_preface.md
02_introduction.md
03_why_markdown_is_useful.md
04_limitations_of_markdown.md
05_conclusions.md
06_links.md

So part of your 01_preface.md could look like this:

I always wanted to write a book with [markdown][mkdnlink].

And part of your 02_introduction.md could look like this:

Let's start digging into [the best text-based syntax][mkdnlink] available.

As long as your last file includes the line:

[mkdnlink]: http://daringfireball.net/projects/markdown

...the same command used before will perform the merge and conversion while including that link throughout. Just make sure you leave a blank line or two at the beginning of that file. The pandoc documentation says that it adds a blank line between files that are merged this way, but this didn't work for me without the blank line.

I had the same issue, and I couldn't comment on @Sven Marnach answer (not enough rep, gosh I remember when Stackoverflow first started...) anyway.

Adding a list of random numbers to a 10 X 10 matrix.

myNpArray = np.zeros([1, 10])
for x in range(1,11,1):
    randomList = [list(np.random.randint(99, size=10))]
    myNpArray = np.vstack((myNpArray, randomList))
myNpArray = myNpArray[1:]

Using np.zeros() an array is created with 1 x 10 zeros.

array([[0., 0., 0., 0., 0., 0., 0., 0., 0., 0.]])

Then a list of 10 random numbers is created using np.random and assigned to randomList. The loop stacks it 10 high. We just have to remember to remove the first empty entry.

myNpArray

array([[31., 10., 19., 78., 95., 58.,  3., 47., 30., 56.],
       [51., 97.,  5., 80., 28., 76., 92., 50., 22., 93.],
       [64., 79.,  7., 12., 68., 13., 59., 96., 32., 34.],
       [44., 22., 46., 56., 73., 42., 62.,  4., 62., 83.],
       [91., 28., 54., 69., 60., 95.,  5., 13., 60., 88.],
       [71., 90., 76., 53., 13., 53., 31.,  3., 96., 57.],
       [33., 87., 81.,  7., 53., 46.,  5.,  8., 20., 71.],
       [46., 71., 14., 66., 68., 65., 68., 32.,  9., 30.],
       [ 1., 35., 96., 92., 72., 52., 88., 86., 94., 88.],
       [13., 36., 43., 45., 90., 17., 38.,  1., 41., 33.]])

So in a function:

def array_matrix(random_range, array_size):
    myNpArray = np.zeros([1, array_size])
    for x in range(1, array_size + 1, 1):
        randomList = [list(np.random.randint(random_range, size=array_size))]
        myNpArray = np.vstack((myNpArray, randomList))
    return myNpArray[1:]

This is a quick hacky way: ls -lart | grep -v ^total.

Basically, remove any lines that start with "total", which in ls output should only be the first line.

A more general way (for anything):

ls -lart | sed "1 d"

sed "1 d" means only print everything but first line.

In my situation, our IT department made MFA mandatory for our domain. This means we can only use option 3 in this Microsoft article to send email. Option 3 involves setting up an SMTP relay using an Office365 Connector.

It can take time for the network close to be observed - the total time is nominally about 2 minutes (yes, minutes!) after a close before the packets destined for the port are all assumed to be dead. The error condition is detected at some point. With a small write, you are inside the MTU of the system, so the message is queued for sending. With a big write, you are bigger than the MTU and the system spots the problem quicker. If you ignore the SIGPIPE signal, then the functions will return EPIPE error on a broken pipe - at some point when the broken-ness of the connection is detected.

something like....

SELECT f.*
      ,a1.city as from
      ,a2.city as to
FROM flights f
INNER JOIN airports a1
ON f.fairport = a1. code
INNER JOIN airports a2
ON f.tairport = a2. code

I'm surprised that no one has mentioned that you can do this with f-strings in Python 3.6+ as easy as this:

>>> num = 10000000
>>> print(f"{num:,}")
10,000,000

... where the part after the colon is the format specifier. The comma is the separator character you want, so f"{num:_}" uses underscores instead of a comma.

This is equivalent of using format(num, ",") for older versions of python 3.

Let's say you have 25 objects and want one process to handle any one objects click event. You could write 25 delegates or use a loop to handle the click event.

public form1()
{
    foreach (Panel pl  in Container.Components)
    {
        pl.Click += Panel_Click;
    }
}

private void Panel_Click(object sender, EventArgs e)
{
    // Process the panel clicks here
    int index = Panels.FindIndex(a => a == sender);
    ...
}

It's possible to use a function, which evaluates the OR logic and returns a single value.

@echo off
set var1=3
set var2=5
call :logic_or orResult "'%var1%'=='4'" "'%var2%'=='5'"
if %orResult%==1 ( 
    echo At least one expression is true
) ELSE echo All expressions are false
exit /b

:logic_or <resultVar> expression1 [[expr2] ... expr-n] 
SETLOCAL
set "logic_or.result=0"
set "logic_or.resultVar=%~1"

:logic_or_loop 
if "%~2"=="" goto :logic_or_end 
if %~2 set "logic_or.result=1"
SHIFT 
goto :logic_or_loop 

:logic_or_end 
( 
  ENDLOCAL 
  set "%logic_or.resultVar%=%logic_or.result%"
  exit /b
) 

Functionally, they are equivalent.

Performance-wise map[key] = value would be quicker, as you are only making single lookup instead of two.

Style-wise, the shorter the better :)

The code will in most cases seem to work fine in multi-threaded context. It however is not thread-safe without extra synchronization.

Remove key and then add again the modified key, value pair as shown below :

    JSONObject js = new JSONObject();
    js.put("name", "rai");

    js.remove("name");
    js.put("name", "abc");

I haven't used your example; but conceptually its same.

> myMatrix <- matrix(1:10, nrow=2)
> rownames(myMatrix) <- c("A", "B")
> colnames(myMatrix) <- c("A", "B", "C", "D", "E")

> myMatrix
  A B C D  E
A 1 3 5 7  9
B 2 4 6 8 10

> myMatrix["A", "A"]
[1] 1

> myMatrix["A", ]
A B C D E 
1 3 5 7 9 

> myMatrix[, "A"]
A B 
1 2 

Since array literal notation is still valid JSON, you can use JSON.parse() to convert that string into an array, and from there, use it's values.

var test = "[1,2]";
parsedTest = JSON.parse(test); //an array [1,2]

//access like and array
console.log(parsedTest[0]); //1
console.log(parsedTest[1]); //2

There is one big difference between malloc and new. malloc allocates memory. This is fine for C, because in C, a lump of memory is an object.

In C++, if you're not dealing with POD types (which are similar to C types) you must call a constructor on a memory location to actually have an object there. Non-POD types are very common in C++, as many C++ features make an object automatically non-POD.

new allocates memory and creates an object on that memory location. For non-POD types this means calling a constructor.

If you do something like this:

non_pod_type* p = (non_pod_type*) malloc(sizeof *p);

The pointer you obtain cannot be dereferenced because it does not point to an object. You'd need to call a constructor on it before you can use it (and this is done using placement new).

If, on the other hand, you do:

non_pod_type* p = new non_pod_type();

You get a pointer that is always valid, because new created an object.

Even for POD types, there's a significant difference between the two:

pod_type* p = (pod_type*) malloc(sizeof *p);
std::cout << p->foo;

This piece of code would print an unspecified value, because the POD objects created by malloc are not initialised.

With new, you could specify a constructor to call, and thus get a well defined value.

pod_type* p = new pod_type();
std::cout << p->foo; // prints 0

If you really want it, you can use use new to obtain uninitialised POD objects. See this other answer for more information on that.

Another difference is the behaviour upon failure. When it fails to allocate memory, malloc returns a null pointer, while new throws an exception.

The former requires you to test every pointer returned before using it, while the later will always produce valid pointers.

For these reasons, in C++ code you should use new, and not malloc. But even then, you should not use new "in the open", because it acquires resources you need to release later on. When you use new you should pass its result immediately into a resource managing class:

std::unique_ptr<T> p = std::unique_ptr<T>(new T()); // this won't leak

A well-explained answer is already given by @mkobit, but I will add a big picture of the range key and hash key.

In a simple words range + hash key = composite primary key CoreComponents of Dynamodb

A primary key is consists of a hash key and an optional range key. Hash key is used to select the DynamoDB partition. Partitions are parts of the table data. Range keys are used to sort the items in the partition, if they exist.

So both have a different purpose and together help to do complex query. In the above example hashkey1 can have multiple n-range. Another example of range and hashkey is game, userA(hashkey) can play Ngame(range)

The Music table described in Tables, Items, and Attributes is an example of a table with a composite primary key (Artist and SongTitle). You can access any item in the Music table directly, if you provide the Artist and SongTitle values for that item.

A composite primary key gives you additional flexibility when querying data. For example, if you provide only the value for Artist, DynamoDB retrieves all of the songs by that artist. To retrieve only a subset of songs by a particular artist, you can provide a value for Artist along with a range of values for SongTitle.

Beside using loop and for comprehension, you could also use map

lst = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")]
mylst = map(lambda each:each.strip("8"), lst)
print mylst

In principle, no.

It's not written in stone; but it's the way all APIs are written: the app opens a port, gets a handle to it, and the OS notifies it (via that handle) when a client connection (or a packet in UDP case) arrives.

If the OS allowed two apps to open the same port, how would it know which one to notify?

But... there are ways around it:

1. As Jed noted, you could write a 'master' process, which would be the only one that really listens on the port and notifies others, using any logic it wants to separate client requests.
   • On Linux and BSD (at least) you can set up 'remapping' rules that redirect packets from the 'visible' port to different ones (where the apps are listening), according to any network related criteria (maybe network of origin, or some simple forms of load balancing).

For the most part you treat it as if you are validating any other kind of control but use the InitialValue property of the required field validator.

<asp:RequiredFieldValidator ID="rfv1" runat="server" ControlToValidate="your-dropdownlist" InitialValue="Please select" ErrorMessage="Please select something" />

Basically what it's saying is that validation will succeed if any other value than the 1 set in InitialValue is selected in the dropdownlist.

If databinding you will need to insert the "Please select" value afterwards as follows

this.ddl1.Items.Insert(0, "Please select");

As others have indicated, Process.Start() is the way to go here. However, there are a few quirks. It's worth your time to read this blog post:

http://faithlife.codes/blog/2008/01/using_processstart_to_link_to/

In summary, some browsers cause it to throw an exception for no good reason, the function can block for a while on non-UI thread so you need to make sure it happens near the end of whatever other actions you might perform at the same time, and you might want to change the cursor appearance while waiting for the browser to open.

use DateTime.Now

try this:

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

To open and read a text file line per line, you could use the following:

// define your file name
string file_name = "data.txt";

// attach an input stream to the wanted file
ifstream input_stream(file_name);

// check stream status
if (!input_stream) cerr << "Can't open input file!";

// file contents  
vector<string> text;

// one line
string line;

// extract all the text from the input file
while (getline(input_stream, line)) {

    // store each line in the vector
    text.push_back(line);
}

To open and read a binary file you need to explicitly declare the reading format in your input stream to be binary, and read memory that has no explicit interpretation using stream member function read():

// define your file name
string file_name = "binary_data.bin";

// attach an input stream to the wanted file
ifstream input_stream(file_name, ios::binary);

// check stream status
if (!input_stream) cerr << "Can't open input file!";

// use function that explicitly specifies the amount of block memory read 
int memory_size = 10;

// allocate 10 bytes of memory on heap
char* dynamic_buffer = new char[memory_size];

// read 10 bytes and store in dynamic_buffer
file_name.read(dynamic_buffer, memory_size);

When doing this you'll need to #include the header : <iostream>

Actually the only two strategies you would want to choose are ours if you want to abandon changes brought by branch, but keep the branch in history, and subtree if you are merging independent project into subdirectory of superproject (like 'git-gui' in 'git' repository).

octopus merge is used automatically when merging more than two branches. resolve is here mainly for historical reasons, and for when you are hit by recursive merge strategy corner cases.

I think this might have updated with jQuery 1.9.*

I'm finding the this is the only thing that works for me at the moment:

$._data($("#yourElementID")[0]).events

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

In front-end JavaScript/HTML, you can load a binary file as an image, you do not have to convert to base64:

<img src="http://engci.nabisco.com/artifactory/repo/folder/my-image">

my-image is a binary image file. This will load just fine.

"Add a reference to MySql.Data.dll" means you need to add a library reference to the downloaded connector. The IDE will link the database connection library with your application when it compiles.

Step-by-Step Example

I downloaded the binary (no installer) zip package from the MySQL web site, extracted onto the desktop, and did the following:

1. Create a new project in Visual Studio
2. In the Solution Explorer, under the project name, locate References and right-click on it. Select "Add Reference".
3. In the "Add Reference" dialog, switch to the "Browse" tab and browse to the folder containing the downloaded connector. Navigate to the "bin" folder, and select the "MySql.Data.dll" file. Click OK.
4. At the top of your code, add using MySql.Data.MySqlClient;. If you've added the reference correctly, IntelliSense should offer to complete this for you.

Yes there is a major difference between the two methods Use delete_all if you want records to be deleted quickly without model callbacks being called

If you care about your models callbacks then use destroy_all

From the official docs

http://apidock.com/rails/ActiveRecord/Base/destroy_all/class

destroy_all(conditions = nil) public

Destroys the records matching conditions by instantiating each record and calling its destroy method. Each object’s callbacks are executed (including :dependent association options and before_destroy/after_destroy Observer methods). Returns the collection of objects that were destroyed; each will be frozen, to reflect that no changes should be made (since they can’t be persisted).

Note: Instantiation, callback execution, and deletion of each record can be time consuming when you’re removing many records at once. It generates at least one SQL DELETE query per record (or possibly more, to enforce your callbacks). If you want to delete many rows quickly, without concern for their associations or callbacks, use delete_all instead.

You need to use brackets when using the fileExists step in an if condition or assign the returned value to a variable

Using variable:

def exists = fileExists 'file'

if (exists) {
    echo 'Yes'
} else {
    echo 'No'
}

Using brackets:

if (fileExists('file')) {
    echo 'Yes'
} else {
    echo 'No'
}

Try this:

HTML:

<input type="submit" value="submit" name="submit" onclick="myfunction()">

jQuery:

<script type="text/javascript">
 function myfunction() 
 {
    var url = $(location).attr('href');
    $('#spn_url').html('<strong>' + url + '</strong>');
 }

Use the built-in python function quit() and that's it. No need to import any library. I'm using python 3.4

The current answer did not work good for me, if the exception is not re-caught the appended message is not shown.

But doing like below both keeps the trace and shows the appended message regardless if the exception is re-caught or not.

try:
  raise ValueError("Original message")
except ValueError as err:
  t, v, tb = sys.exc_info()
  raise t, ValueError(err.message + " Appended Info"), tb

This is the "DTHML" HTML5 way to do it. Normal form input (which IS read only as Ricardo Tomasi pointed out). Then if a file is dragged in, it is attached to the form. This WILL require modification to the action page to accept the file uploaded this way.

It is even more boss if you can make the whole window a drop zone, see How do I detect a HTML5 drag event entering and leaving the window, like Gmail does?

Plain javascript: document.location = 'http://www.google.com';

This will cause a browser refresh though - consider using hashes if you're in need of having the URL updated to implement some kind of browsing history without reloading the page. You might want to look into jQuery.hashchange if this is the case.

An object is a construct, something static that has certain features and traits, such as properties and methods, it can be anything (a string, a usercontrol, etc)

An instance is a unique copy of that object that you can use and do things with.

Imagine a product like a computer.

THE xw6400 workstation is an object

YOUR xw6400 workstation, (or YOUR WIFE's xw6400 workstation) is an instance of the xw6400 workstation object

$diff_min = ( strtotime( $day2 ) - strtotime( $day1 ) ) / 60 / 60;
$total_time  = $diff_min;

You can try this one.

Another possibility: When you created the user, you may have accidentally been useing a database other than admin, or other than the one you wanted. You need to set --authenticationDatabase to the database that the user was actually created under.

mongodb seems to put you in the test database by default when you open the shell, so you'd need to write --authenticationDatabase test rather than --authenticationDatabase admin if you accidentally were useing test when you ran db.createUser(...).

Assuming you have access to the machine that's running the mongodb instance, y could disable authorization in /etc/mongod.conf (comment out authorization which is nested under security), and then restart your server, and then run:

mongo
show users

And you might get something like this:

{
    "_id" : "test.myusername",
    "user" : "myusername",
    "db" : "test",
    "roles" : [
        {
            "role" : "dbOwner",
            "db" : "mydatabasename"
        }
    ],
    "mechanisms" : [
        "SCRAM-SHA-1",
        "SCRAM-SHA-256"
    ]
}

Notice that the db value equals test. That's because when I created the user, I didn't first run use admin or use desiredDatabaseName. So you can delete the user with db.dropUser("myusername") and then create another user under your desired database like so:

use desiredDatabaseName
db.createUser(...)

Hopefully that helps someone who was in my position as a noob with this stuff.

If you have custom attributes in appsetting. move your

     <configSections> 
     </configSections>

tag to the first child in the <confuguration>.

I was having the same issue and tried all of the solutions on this page but none of them did the trick.

What finally worked was adding the universe repo to my repo list. To do that run the following command

sudo add-apt-repository universe

After running the above command I was able to run

sudo apt install openjdk-8-jre

without an issue and the package was installed.

Hope this helps someone.

I received the same error message. To resolve this I just replaced the Oracle.ManagedDataAccess assembly with the older Oracle.DataAccess assembly. This solution may not work if you require new features found in the new assembly. In my case I have many more higher priority issues then trying to configure the new Oracle assembly.

You could use Faux Columns.

Basically it uses a background image in a containing DIV to simulate the two equal-height-DIVs. Using this technique also allowes you to add shadows, rounded corners, custom borders or other funky patterns to your containers.

Only works with fixed-width boxes though.

Well tested out and properly working in every browser.

If you are using the codeigniter framework and are testing the project on a localhost, open the main Index.php file of your project folder and find this code:

define('ENVIRONMENT', 'production');

Change it to

define ('ENVIRONMENT', 'development');

Because same this ENVIRONMENT is in your database.php file under config folder. like this:

 'db_debug' => (ENVIRONMENT! == 'development')

So the environment should be the same in both places and problem will be solved.

I think I know what may cause this error.

In google chrome there is an in-built feature to prevent ddos attacks for google chrome extensions.

When ajax requests continuously return 500+ status errors, it starts to throttle the requests.

Hence it is possible to receive status 0 on following requests.

I think, UNSIGNED would be the best option to store something like time_duration(Eg: resolved_call_time = resolved_time(DateTime)-creation_time(DateTime)) value in minutes or hours or seconds format which will definitely be a non-negative number

Boost Test Library is a very good choice especially if you're already using Boost.

// TODO: Include your class to test here.
#define BOOST_TEST_MODULE MyTest
#include <boost/test/unit_test.hpp>

BOOST_AUTO_TEST_CASE(MyTestCase)
{
    // To simplify this example test, let's suppose we'll test 'float'.
    // Some test are stupid, but all should pass.
    float x = 9.5f;

    BOOST_CHECK(x != 0.0f);
    BOOST_CHECK_EQUAL((int)x, 9);
    BOOST_CHECK_CLOSE(x, 9.5f, 0.0001f); // Checks differ no more then 0.0001%
}

It supports:

• Automatic or manual tests registration
• Many assertions
• Automatic comparison of collections
• Various output formats (including XML)
• Fixtures / Templates...

PS: I wrote an article about it that may help you getting started: C++ Unit Testing Framework: A Boost Test Tutorial

Imagine incrementing a counter in some component:

  class SomeComponent extends Component{

    state = {
      updatedByDiv: '',
      updatedByBtn: '',
      counter: 0
    }

    divCountHandler = () => {
      this.setState({
        updatedByDiv: 'Div',
        counter: this.state.counter + 1
      });
      console.log('divCountHandler executed');
    }

    btnCountHandler = () => {
      this.setState({
        updatedByBtn: 'Button',
        counter: this.state.counter + 1
      });
      console.log('btnCountHandler executed');
    }
    ...
    ...
    render(){
      return (
        ...
        // a parent div
        <div onClick={this.divCountHandler}>
          // a child button
          <button onClick={this.btnCountHandler}>Increment Count</button>
        </div>
        ...
      )
    }
  }

There is a count handler attached to both the parent and the child components. This is done purposely so we can execute the setState() twice within the same click event bubbling context, but from within 2 different handlers.

As we would imagine, a single click event on the button would now trigger both these handlers since the event bubbles from target to the outermost container during the bubbling phase.

Therefore the btnCountHandler() executes first, expected to increment the count to 1 and then the divCountHandler() executes, expected to increment the count to 2.

However the count only increments to 1 as you can inspect in React Developer tools.

This proves that react

• queues all the setState calls

• comes back to this queue after executing the last method in the context(the divCountHandler in this case)

• merges all the object mutations happening within multiple setState calls in the same context(all method calls within a single event phase is same context for e.g.) into one single object mutation syntax (merging makes sense because this is why we can update the state properties independently in setState() in the first place)

• and passes it into one single setState() to prevent re-rendering due to multiple setState() calls (this is a very primitive description of batching).

Resultant code run by react:

this.setState({
  updatedByDiv: 'Div',
  updatedByBtn: 'Button',
  counter: this.state.counter + 1
})

To stop this behaviour, instead of passing objects as arguments to the setState method, callbacks are passed.

    divCountHandler = () => {
          this.setState((prevState, props) => {
            return {
              updatedByDiv: 'Div',
              counter: prevState.counter + 1
            };
          });
          console.log('divCountHandler executed');
        }

    btnCountHandler = () => {
          this.setState((prevState, props) => {
            return {
              updatedByBtn: 'Button',
              counter: prevState.counter + 1
            };
          });
      console.log('btnCountHandler executed');
    }

After the last method finishes execution and when react returns to process the setState queue, it simply calls the callback for each setState queued, passing in the previous component state.

This way react ensures that the last callback in the queue gets to update the state that all of its previous counterparts have laid hands on.

Here's a more portable version (just for fun, it is not necessary in your case):

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from subprocess import Popen, PIPE, STDOUT

try:
    from subprocess import DEVNULL # py3k
except ImportError:
    import os
    DEVNULL = open(os.devnull, 'wb')

text = u"René Descartes"
p = Popen(['espeak', '-b', '1'], stdin=PIPE, stdout=DEVNULL, stderr=STDOUT)
p.communicate(text.encode('utf-8'))
assert p.returncode == 0 # use appropriate for your program error handling here

Update:

ngKeypress, ngKeydown and ngKeyup are now part of AngularJS.

<!-- you can, for example, specify an expression to evaluate -->
<input ng-keypress="count = count + 1" ng-init="count=0">

<!-- or call a controller/directive method and pass $event as parameter.
     With access to $event you can now do stuff like 
     finding which key was pressed -->
<input ng-keypress="changed($event)">

Earlier solutions:

Solution 1: Use ng-change with ng-model

<input type="text" placeholder="+639178983214" ng-model="mobileNumber" 
ng-controller="RegisterDataController" ng-change="keydown()">

JS:

function RegisterDataController($scope) {       
   $scope.keydown = function() {
        /* validate $scope.mobileNumber here*/
   };
}

Solution 2. Use $watch

<input type="text" placeholder="+639178983214" ng-model="mobileNumber" 
ng-controller="RegisterDataController">
    

JS:

$scope.$watch("mobileNumber", function(newValue, oldValue) {
    /* change noticed */
});

2^8 = 256 Characters. A character in binary is a series of 8 ( 0 or 1).

As odd as it sound when you want to permit nested attributes you do specify the attributes of nested object within an array. In your case it would be

Update as suggested by @RafaelOliveira

params.require(:measurement)
      .permit(:name, :groundtruth => [:type, :coordinates => []])

On the other hand if you want nested of multiple objects then you wrap it inside a hash… like this

params.require(:foo).permit(:bar, {:baz => [:x, :y]})

Rails actually have pretty good documentation on this: http://api.rubyonrails.org/classes/ActionController/Parameters.html#method-i-permit

For further clarification, you could look at the implementation of permit and strong_parameters itself: https://github.com/rails/rails/blob/master/actionpack/lib/action_controller/metal/strong_parameters.rb#L246-L247

Using Functional Components and React Hooks

const [array,setArray] = useState([]);

Push value at the end:

setArray(oldArray => [...oldArray,newValue] );

Push value at the begging:

setArray(oldArray => [newValue,...oldArrays] );

Instead of using a PreferenceActivity to directly load preferences, use an AppCompatActivity or equivalent that loads a PreferenceFragmentCompat that loads your preferences. It's part of the support library (now Android Jetpack) and provides compatibility back to API 14.

In your build.gradle, add a dependency for the preference support library:

dependencies {
    // ...
    implementation "androidx.preference:preference:1.0.0-alpha1"
}

Note: We're going to assume you have your preferences XML already created.

For your activity, create a new activity class. If you're using material themes, you should extend an AppCompatActivity, but you can be flexible with this:

public class MyPreferencesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_preferences_activity)
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, MyPreferencesFragment())
                    .commitNow()
        }
    }
}

Now for the important part: create a fragment that loads your preferences from XML:

public class MyPreferencesFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.my_preferences_fragment); // Your preferences fragment
    }
}

For more information, read the Android Developers docs for PreferenceFragmentCompat.

You can use the dynamic variable ViewBag

ViewBag.AnotherValue = valueToView;

Try doing this:

Set-Item WSMan:\localhost\Client\TrustedHosts -Value "*" -Force

When you define varchar etc without a length, the default is 1.

When n is not specified in a data definition or variable declaration statement, the default length is 1. When n is not specified with the CAST function, the default length is 30.

So, if you expect 400 bytes in the @trackingItems1 column from stock, use nvarchar(400).

Otherwise, you are trying to fit >1 character into nvarchar(1) = fail

As a comment, this is bad use of table value function too because it is "multi statement". It can be written like this and it will run better

ALTER FUNCTION [dbo].[testing1](@price int)
RETURNS
AS
   SELECT ta.item, ta.warehouse, ta.price 
   FROM   stock ta
   WHERE  ta.price >= @price;

Of course, you could just use a normal SELECT statement..

You should create an Intent object with a geo-URI:

String uri = String.format(Locale.ENGLISH, "geo:%f,%f", latitude, longitude);
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));
context.startActivity(intent);

If you want to specify an address, you should use another form of geo-URI: geo:0,0?q=address.

reference : https://developer.android.com/guide/components/intents-common.html#Maps

MainLabel:BEGIN

IF (<condition>) IS NOT NULL THEN
    LEAVE MainLabel;
END IF; 

....code

i.e.
IF (@skipMe) IS NOT NULL THEN /* @skipMe returns Null if never set or set to NULL */
     LEAVE MainLabel;
END IF;

If you don't mind getting multi-character strings back, you can support arbitrary positive indices:

function idOf(i) {
    return (i >= 26 ? idOf((i / 26 >> 0) - 1) : '') +  'abcdefghijklmnopqrstuvwxyz'[i % 26 >> 0];
}

idOf(0) // a
idOf(1) // b
idOf(25) // z
idOf(26) // aa
idOf(27) // ab
idOf(701) // zz
idOf(702) // aaa
idOf(703) // aab

(Not thoroughly tested for precision errors :)

if you want UTC try some of the gm functions:

import time
import calendar

date_time = '29.08.2011 11:05:02'
pattern = '%d.%m.%Y %H:%M:%S'
utc_epoch = calendar.timegm(time.strptime(date_time, pattern))
print utc_epoch

If you have trouble resolving (like me) and you cannot delete and update the resources because you have made many changes on them, plus you are using eclipse subversive instead of native client, follow these steps:

1. make a copy of your entire project dir
2. perform team>disconnect within eclipse, and choose to delete the svn metadata
3. then choose team>share project, and point to the very same folder that your project resides in
4. choose yes, and commit everything (you may want to exclude some very local resources, like configuration files)
5. if you have deleted or moved some resources prior to your first commit trial, delete those old resources (they should have doubled up, one in old location, one in new) and commit those deletions.

You're done.

The compiler is complaining because you currently have the 'if(exist)' block inside of your for loop. It needs to be outside of it.

for(int i=0;i<this.customers.size();i++){
        if(this.customers.get(i).getId() == id){
            exist=true;
            break;
        }
}

if(exist) {
    return this.customers.get(id);
} else {
    return this.customers.get(id);
}

That being said, there are better ways to perform this search. Personally, if I were using an ArrayList, my solution would look like the one that Jon Skeet has posted.

I faced the same issue(404 on a newly set up GitHub pages website) yesterday. I tried many methods such as switching a new theme etc. But it seems that it still did not work on my case. I finally figured it out by switching the branch of GitHub pages website to another branch, click save. Wait for a while and switch it back again. Then the problem was suddenly solved.

The standard C# convention, which works well enough in Java too, is to prefix all interfaces with an I - so your file handler interface will be IFileHandler and your truck interface will be ITruck. It's consistent, and makes it easy to tell interfaces from classes.

While Dav is correct that the information isn't directly stored, that doesn't mean you can't ever find out. Here are a few things you can do.

Find branches the commit is on

git branch -a --contains <commit>

This will tell you all branches which have the given commit in their history. Obviously this is less useful if the commit's already been merged.

Search the reflogs

If you are working in the repository in which the commit was made, you can search the reflogs for the line for that commit. Reflogs older than 90 days are pruned by git-gc, so if the commit's too old, you won't find it. That said, you can do this:

git reflog show --all | grep a871742

to find commit a871742. Note that you MUST use the abbreviatd 7 first digits of the commit. The output should be something like this:

a871742 refs/heads/completion@{0}: commit (amend): mpc-completion: total rewrite

indicating that the commit was made on the branch "completion". The default output shows abbreviated commit hashes, so be sure not to search for the full hash or you won't find anything.

git reflog show is actually just an alias for git log -g --abbrev-commit --pretty=oneline, so if you want to fiddle with the output format to make different things available to grep for, that's your starting point!

If you're not working in the repository where the commit was made, the best you can do in this case is examine the reflogs and find when the commit was first introduced to your repository; with any luck, you fetched the branch it was committed to. This is a bit more complex, because you can't walk both the commit tree and reflogs simultaneously. You'd want to parse the reflog output, examining each hash to see if it contains the desired commit or not.

Find a subsequent merge commit

This is workflow-dependent, but with good workflows, commits are made on development branches which are then merged in. You could do this:

git log --merges <commit>..

to see merge commits that have the given commit as an ancestor. (If the commit was only merged once, the first one should be the merge you're after; otherwise you'll have to examine a few, I suppose.) The merge commit message should contain the branch name that was merged.

If you want to be able to count on doing this, you may want to use the --no-ff option to git merge to force merge commit creation even in the fast-forward case. (Don't get too eager, though. That could become obfuscating if overused.) VonC's answer to a related question helpfully elaborates on this topic.

I like assylias' answer, however I would refactor it as follows:

Sub test()

Dim origNum As String
Dim creditOrDebit As String

origNum = "30062600006"
creditOrDebit = "D"

If creditOrDebit = "D" Then
  If origNum = "006260006" Then
    MsgBox "OK"
  ElseIf origNum = "30062600006" Then
    MsgBox "OK"
  End If
End If

End Sub

This might save you some CPU cycles since if creditOrDebit is <> "D" there is no point in checking the value of origNum.

Update:

I used the following procedure to test my theory that my procedure is faster:

Public Declare Function timeGetTime Lib "winmm.dll" () As Long

Sub DoTests2()

  Dim startTime1 As Long
  Dim endTime1 As Long
  Dim startTime2 As Long
  Dim endTime2 As Long
  Dim i As Long
  Dim msg As String

  Const numberOfLoops As Long = 10000
  Const origNum As String = "006260006"
  Const creditOrDebit As String = "D"

  startTime1 = timeGetTime
  For i = 1 To numberOfLoops
    If creditOrDebit = "D" Then
      If origNum = "006260006" Then
        ' do something here
        Debug.Print "OK"
      ElseIf origNum = "30062600006" Then
        ' do something here
        Debug.Print "OK"
      End If
    End If
  Next i
  endTime1 = timeGetTime

  startTime2 = timeGetTime
  For i = 1 To numberOfLoops
    If (origNum = "006260006" Or origNum = "30062600006") And _
      creditOrDebit = "D" Then
      ' do something here
      Debug.Print "OK"
    End If
  Next i
  endTime2 = timeGetTime

  msg = "number of iterations: " & numberOfLoops & vbNewLine
  msg = msg & "JP proc: " & Format$((endTime1 - startTime1), "#,###") & _
       " ms" & vbNewLine
  msg = msg & "assylias proc: " & Format$((endTime2 - startTime2), "#,###") & _
       " ms"

  MsgBox msg

End Sub

I must have a slow computer because 1,000,000 iterations took nowhere near ~200 ms as with assylias' test. I had to limit the iterations to 10,000 -- hey, I have other things to do :)

After running the above procedure 10 times, my procedure is faster only 20% of the time. However, when it is slower it is only superficially slower. As assylias pointed out, however, when creditOrDebit is <>"D", my procedure is at least twice as fast. I was able to reasonably test it at 100 million iterations.

And that is why I refactored it - to short-circuit the logic so that origNum doesn't need to be evaluated when creditOrDebit <> "D".

At this point, the rest depends on the OP's spreadsheet. If creditOrDebit is likely to equal D, then use assylias' procedure, because it will usually run faster. But if creditOrDebit has a wide range of possible values, and D is not any more likely to be the target value, my procedure will leverage that to prevent needlessly evaluating the other variable.

path is pointing to a subfolder under c:\Documents & Settings

That's right. ClickOnce applications are installed under the profile of the user who installed them. Did you take the path that retrieving the info from the executing assembly gave you, and go check it out?

On windows Vista and Windows 7, you will find the ClickOnce cache here:

c:\users\username\AppData\Local\Apps\2.0\obfuscatedfoldername\obfuscatedfoldername

On Windows XP, you will find it here:

C:\Documents and Settings\username\LocalSettings\Apps\2.0\obfuscatedfoldername\obfuscatedfoldername

in the apache virtualhost you have to define the path to the error log file. when apache2 start for the first time it will create it automatically.

for example ErrorLog "/var/www/www.localhost.com/log-apache2/error.log" in the apache virtualhost..

this can be done with os.walk()

python 3.5.2 tested;

import os
for root, dirs, files in os.walk('.', topdown=True):
    dirs.clear() #with topdown true, this will prevent walk from going into subs
    for file in files:
      #do some stuff
      print(file)

remove the dirs.clear() line and the files in sub folders are included again.

update with references;

os.walk documented here and talks about the triple list being created and topdown effects.

.clear() documented here for emptying a list

so by clearing the relevant list from os.walk you can effect its result to your needs.

You can remove them from /Library/Developer/CoreSimulator/Profiles/Runtimes (Not ~/Library!):

Here is little simple and less code version. It will hide the console window too-

System.Diagnostics.Process process = new System.Diagnostics.Process();
process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
process.StartInfo.FileName = "cmd.exe";
process.StartInfo.Arguments = "/C copy /b Image1.jpg + Archive.rar Image2.jpg";
process.Start();

A really simple way to do this...

// create the option
var opt = $("<option>").val("myvalue").text("my text");

//append option to the select element
$(#my-select).append(opt);

This could be done in lots of ways, even in a single line if really you want to.

Use EchoX.EXE from the terrific "Shell Scripting Toolkit" by Bill Stewart
How to suppress the linefeed in a Windows Cmd script:

@Echo Off
Rem Print three Echos in one line of output
EchoX -n "Part 1 - "
EchoX -n "Part 2 - "
EchoX    "Part 3"
Rem

gives:

Part 1 - Part 2 - Part 3
{empty line}
d:\Prompt>

The help for this usage is:

Usage: echox [-n] message
  -n       Do not skip to the next line.
  message  The text to be displayed.

The utility is smaller than 48K, and should live in your Path. More things it can do:
- print text without moving to the next line
- print text justified to the left, center, or right, within a certain width
- print text with Tabs, Linefeeds, and Returns
- print text in foreground and background colors

The Toolkit includes twelve more great scripting tricks.
The download page also hosts three other useful tool packages.

You can try this:

const wait_until_element_appear = setInterval(() => {
    if ($(element).length !== 0) {
        // some code
        clearInterval(wait_until_element_appear);
    }
}, 0);

This solution works very good for me

With git there is a https format

https://github.com/equivalent/we_demand_serverless_ruby.git

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

I have a completely different take on this. I use MailHide for this.

MailHide is a system from Google whereby the user needs to complete a reCAPTCHA test to then reveal the email to them.

for those who are having the issue of it still not letting you save once it is changed according to answer below, do the following:

tools -> options -> designers -> Table and Database Designers -> uncheck "prevent saving changes that require table re-creation" box -> OK

and try to save as it should work now

First, find your EditText in the resource of the android studio by using this code:

EditText value = (EditText) findViewById(R.id.editText1);

Then convert EditText value into a string and then parse the value to an int.

int number = Integer.parseInt(x.getText().toString());

This will work

this type of error generally occurs when you have to put characters or values more than that you have specified in Database table like in that case: you specify transaction_status varchar(10) but you actually trying to store _transaction_status which contain 19 characters. that's why you faced this type of error in this code

Do you use the ob_start(ob_gzhandler) function? If so and If you output any content above the ob_start(ob_gzhandler) function, you'll get this error. You can don't use this function or don't output content above this function. The ob_gzhandler callback function will determine what type of content encoding the browser will accept and will return its output accordingly. So if you output content above this function, the content's encoding maybe different from the output content of ob_gzhandler and that cause this error.

For androidx it's called androidx.core.widget.NestedScrollView - and it scrolls alike butter with properties isScrollContainer and measureAllChildren enabled:

<!-- Scrolling Content -->
<androidx.core.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

    android:isScrollContainer="true"
    android:measureAllChildren="true"

    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:fastScrollEnabled="true"
        android:scrollbarStyle="insideInset"
        android:scrollbars="vertical"
        android:splitMotionEvents="false"
        android:verticalScrollbarPosition="right"/>

</androidx.core.widget.NestedScrollView>

You are getting NullPointerException as the "output" is null when the while loop ends. You can collect the output in some buffer and then use it, something like this-

    StringBuilder buffer = new StringBuilder();
    String output;
    System.out.println("Output from Server .... \n");
    while ((output = br.readLine()) != null) {
        System.out.println(output);
        buffer.append(output);
    }
    output = buffer.toString(); // now you have the output
    conn.disconnect();

document.getElementById('yourId')

is the correct way.

the document refers the HTML document that is loaded in the DOM.

and it searches the id using the function getElementById() which takes a parameter of the id of an element

Solution will be :

var elem = (document.getElementById('myElement'))? document.getElementById('myElement').value : '';

/* this will assign a value or give you and empty string */

The problem might be your split() call. Try just split(" ") without the square brackets.

1. If you want to integrate Retrofit (all steps defined here):

  private static final String BASE_URL = "http://api.twitter.com/1/";
 
  private static AsyncHttpClient client = new AsyncHttpClient();

  public static void get(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(getAbsoluteUrl(url), params, responseHandler);
  }

  public static void post(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(getAbsoluteUrl(url), params, responseHandler);
  }
      
  public static void getByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.get(url, params, responseHandler);
  }

  public static void postByUrl(String url, RequestParams params, AsyncHttpResponseHandler responseHandler) {
      client.post(url, params, responseHandler);
  }

  private static String getAbsoluteUrl(String relativeUrl) {
      return BASE_URL + relativeUrl;
  }
}

Call Method :

    RequestParams rp = new RequestParams();
    rp.add("username", "aaa"); rp.add("password", "aaa@123");
                    
    HttpUtils.post(AppConstant.URL_FEED, rp, new JsonHttpResponseHandler() {
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
            // If the response is JSONObject instead of expected JSONArray
            Log.d("asd", "---------------- this is response : " + response);
            try {
                JSONObject serverResp = new JSONObject(response.toString());                                                
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }                   
        }
            
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
            // Pull out the first event on the public timeline
                    
        }
    });

Please grant internet permission in your manifest file.

 <uses-permission android:name="android.permission.INTERNET" />

you can add compile 'com.loopj.android:android-async-http:1.4.9' for Header[] and compile 'org.json:json:20160212' for JSONObject in build.gradle file if required.

Sorry for the VB code . . . you can convert it to C# if that is your pleasure. The company I am working for right now requires VB :(

In JavaScript ES6 .forEach() over an array-like NodeList collection given by Element.querySelectorAll()

document.querySelectorAll('.testimonial').forEach( el => {_x000D_
  el.style.color = 'red';_x000D_
  console.log( `Element ${el.tagName} with ID #${el.id} says: ${el.textContent}` );_x000D_
});

<p class="testimonial" id="1">This is some text</p>_x000D_
<div class="testimonial" id="2">Lorem ipsum</div>

We can add drawable .xml like below

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


    <stroke
        android:width="1dp"
        android:color="@color/color_C4CDD5"/>

    <corners android:radius="8dp"/>

    <solid
        android:color="@color/color_white"/>

You can use sys.platform:

from sys import platform
if platform == "linux" or platform == "linux2":
    # linux
elif platform == "darwin":
    # OS X
elif platform == "win32":
    # Windows...

sys.platform has finer granularity than sys.name.

For the valid values, consult the documentation.

See also the answer to “What OS am I running on?”

There are indeed global variables in javascript. You can learn more about scopes, which are helpful in this situation.

Your code could look like this:

<script>
    var count = 1;
    function setColor(btn, color) {
        var property = document.getElementById(btn);
        if (count == 0) {
            property.style.backgroundColor = "#FFFFFF"
            count = 1;        
        }
        else {
            property.style.backgroundColor = "#7FFF00"
            count = 0;
        }
    }
</script>

Hope this helps.

My experience is the same as the benchmarks. Python can be slow and uses more memory. I write much, much less code and it works the first time with much less debugging. Since it manages memory for me, I don't have to do any memory management, saving hours of chasing down core leaks.

What's your question?

=VLOOKUP(A2,IF(B1:B3="B",A1:C3,""),1,FALSE)

Ctrl+Shift+Enter to enter.

I think a correct approach would be by means of Regex:

String fileContent = <text from file>;    
String[] words = Pattern.compile("\\s+").split(fileContent);
System.out.println("File has " + words.length + " words");

Hope it helps. The "\s+" meaning is in Pattern javadoc

The best and fastest option, rather than storing everything in a list and re-opening the file to write it, is in my opinion to re-write the file elsewhere.

with open("yourfile.txt", "r") as file_input:
    with open("newfile.txt", "w") as output: 
        for line in file_input:
            if line.strip("\n") != "nickname_to_delete":
                output.write(line)

That's it! In one loop and one only you can do the same thing. It will be much faster.

No, you would have to use a for-loop for that.

for (int i = 0; i < lst1.Count; i++)
{
    //lst1[i]...
    //lst2[i]...
}

You can't do something like

foreach (var objCurrent1 int lst1, var objCurrent2 in lst2)
{
    //...
}
