To create a new helper you can follow the instructions from The Pixel Developer, but my advice is not to create a helper just for the logic required by a particular part of a particular application. Instead, use that logic in the controller to set the arrays to their final intended values. Once you got that, you pass them to the view using the Template Parser Class and (hopefully) you can keep the view clean from anything that looks like PHP using simple variables or variable tag pairs instead of echos and foreachs. i.e:

{blog_entries}
<h5>{title}</h5>
<p>{body}</p>
{/blog_entries}

instead of

<?php foreach ($blog_entries as $blog_entry): ?>
<h5><?php echo $blog_entry['title']; ?></h5>
<p><?php echo $blog_entry['body']; ?></p>
<?php endforeach; ?>

Another benefit from this approach is that you don't have to worry about adding the CI instance as you would if you use custom helpers to do all the work.

Try

android:layout_centerHorizontal="true"

Exactly like this, it works for me:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:background="#ff0000">

    <Button
        android:id="@+id/btn_mybutton"
        android:layout_height="wrap_content"
        android:layout_width="124dip"
        android:layout_marginTop="5dip"
        android:layout_centerHorizontal="true"/>

</RelativeLayout>

I am not too sure, but you could try using a horizontal rule and pushing the text above its top margin. You will need a fixed width on your paragraph tag and a background too. It's a little hacky and I don't know if it will work on all browsers, and you need to set the negative margin based on the size of the font. Works on chrome though.

<style>   
 p{ margin-top:-20px; background:#fff; width:20px;}
</style>

<hr><p>def</p>

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

By default, on many platforms the short will be aligned to an offset at a multiple of 2, so there will be a padding byte added after the char.

To disable this, use: struct.unpack("=BH", data). This will use standard alignment, which doesn't add padding:

>>> struct.calcsize('=BH')
3

The = character will use native byte ordering. You can also use < or > instead of = to force little-endian or big-endian byte ordering, respectively.

I did it this way. Firstly, don't push your changes or you are out of luck. Grab and install the collapse extension. Commit another dummy changeset. Then use collapse to combine the previous two changesets into one. It will prompt you for a new commit message, giving you the messages that you already have as a starting point. You have effectively changed your original commit message.

Unless you can get PHP to label that element with a class you are better to use jQuery.

jQuery(document).ready(function () {
  $count =  jQuery("ul li").size() - 1;
  alert($count);
  jQuery("ul li:nth-child("+$count+")").css("color","red");
});

Using the selectedOptions property:

var yourSelect = document.getElementById("your-select-id");
alert(yourSelect.selectedOptions[0].value);

It works in all browsers except Internet Explorer.

This answer does not destroy instance id, instead it is able to get current one. It also store refreshed one in Shared preferences.

Strings.xml

<string name="pref_firebase_instance_id_key">pref_firebase_instance_id</string>
<string name="pref_firebase_instance_id_default_key">default</string>

Utility.java (any class where you want to set/get preferences)

public static void setFirebaseInstanceId(Context context, String InstanceId) {
    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
    SharedPreferences.Editor editor;
    editor = sharedPreferences.edit();
    editor.putString(context.getString(R.string.pref_firebase_instance_id_key),InstanceId);
    editor.apply();
}

public static String getFirebaseInstanceId(Context context) {
    SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);
    String key = context.getString(R.string.pref_firebase_instance_id_key);
    String default_value = context.getString(R.string.pref_firebase_instance_id_default_key);
    return sharedPreferences.getString(key, default_value);
}

MyFirebaseInstanceIdService.java (extends FirebaseInstanceIdService)

@Override
public void onCreate()
{
    String CurrentToken = FirebaseInstanceId.getInstance().getToken();

    //Log.d(this.getClass().getSimpleName(),"Inside Instance on onCreate");
    String savedToken = Utility.getFirebaseInstanceId(getApplicationContext());
    String defaultToken = getApplication().getString(R.string.pref_firebase_instance_id_default_key);

    if(CurrentToken != null && !savedToken.equalsIgnoreCase(defaultToken))
    //currentToken is null when app is first installed and token is not available
    //also skip if token is already saved in preferences...
    {
        Utility.setFirebaseInstanceId(getApplicationContext(),CurrentToken);
    }
    super.onCreate();
}

@Override
public void onTokenRefresh() {
     .... prev code
      Utility.setFirebaseInstanceId(getApplicationContext(),refreshedToken);
     ....

}

Android 2.0 and above onCreate of service is not invoked when started automatically (source). Instead onStartCommand is overridden and used. But in actual FirebaseInstanceIdService it is declared as final and can't be overridden. However, when we start service using startService(), if service is already running, its original instance is used (which is good). Our onCreate() (defined above) also got invoked!.

Use this in begining of MainActivity or at whichever point you think you need instance id.

MyFirebaseInstanceIdService myFirebaseInstanceIdService = new MyFirebaseInstanceIdService();
Intent intent= new Intent(getApplicationContext(),myFirebaseInstanceIdService.getClass());
//Log.d(this.getClass().getSimpleName(),"Starting MyFirebaseInstanceIdService");
startService(intent); //invoke onCreate

And Finally,

Utility.getFirebaseInstanceId(getApplicationContext())

Note, you can futher enhance this by trying to move startservice() code to getFirebaseInstanceId method.

In more simple terms:

Technically, the -u flag adds a tracking reference to the upstream server you are pushing to.

What is important here is that this lets you do a git pull without supplying any more arguments. For example, once you do a git push -u origin master, you can later call git pull and git will know that you actually meant git pull origin master.

Otherwise, you'd have to type in the whole command.

I had this problem today, and all one-liners here failed to me because the files contained spaces in the names.

This is what I came up with that worked:

grep -ril <WORD1> | sed 's/.*/"&"/' | xargs grep -il <WORD2>

Using EnumerateFiles to get files in nested directories. Use AllDirectories to recurse throught directories.

using System;
using System.IO;

class Program
{
    static void Main()
    {
    // Call EnumerateFiles in a foreach-loop.
    foreach (string file in Directory.EnumerateFiles(@"c:\files",
        "*.xml",
        SearchOption.AllDirectories))
    {
        // Display file path.
        Console.WriteLine(file);
    }
    }
}

Sprintf is what you are looking for.

Example

fmt.Sprintf("foo: %s", bar)

You can also see it in use in the Errors example as part of "A Tour of Go."

return fmt.Sprintf("at %v, %s", e.When, e.What)

There some kind of old school 'Marxismic' way to the cast int -> bool without C4800 warnings of Microsoft's cl compiler - is to use negation of negation.

int  i  = 0;
bool bi = !!i;

int  j  = 1;
bool bj = !!j;

Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.

Determine if a cell is within a range using VBA in Microsoft Excel:

From the linked site (maintaining credit to original submitter):

VBA macro tip contributed by Erlandsen Data Consulting offering Microsoft Excel Application development, template customization, support and training solutions

Function InRange(Range1 As Range, Range2 As Range) As Boolean
    ' returns True if Range1 is within Range2
    InRange = Not (Application.Intersect(Range1, Range2) Is Nothing)
End Function


Sub TestInRange()
    If InRange(ActiveCell, Range("A1:D100")) Then
        ' code to handle that the active cell is within the right range
        MsgBox "Active Cell In Range!"
    Else
        ' code to handle that the active cell is not within the right range
        MsgBox "Active Cell NOT In Range!"
    End If
End Sub

Well, I can think of a CSS hack that will resolve this issue.

You could add the following line in your CSS file:

* html .blog_list div.postbody img { width:75px; height: SpecifyHeightHere; } 

The above code will only be seen by IE6. The aspect ratio won't be perfect, but you could make it look somewhat normal. If you really wanted to make it perfect, you would need to write some javascript that would read the original picture width, and set the ratio accordingly to specify a height.

This is a very simple code I use and you manipulate it to change the colour and size of the table as you see fit.

First connect to the database:

<?php
$connect=mysql_connect('localhost', 'root', 'password');

mysql_select_db("name");
//here u select the data you want to retrieve from the db

$query="select * from tablename";

$result= mysql_query($query);

//here you check to see if any data has been found and you define the width of the table

If($result){

echo "<table width ='340' align='left'>
      <tr color ='#5D9951>";
$i=0;

    If(mysql_num_rows($result)>0)
    {
         //here you fetch the data from the database and print it in the respective columns   
        while($i<mysql_num_fields($result))
        {    
             echo "<th>".mysql_field_name($result, $i)."</th>";
             $i++;
        }
        echo "</tr>";

        $color=1;

        while($rows=mysql_fetch_array($result, MYSQL_ASSOC))
        {    
            If ($color==1){
                echo "<tr color='#'#cccccc'>";

                foreach ($rows as $data){
                    echo "<td align='center'>".$data. "</td>";
                }

                $color=2;
            }
            $color=1;
        }
     } else {
        echo"no results found";
        echo "</table>";
    } else {
        echo "error running query:".MYSQL_error();
}
?>

It's a very elementary piece of code but it helps if you are not used to using functions.

Just becuase your class object has no variables does not mean that it is nothing. Declaring and object and creating an object are two different things. Look and see if you are setting/creating the object.

Take for instance the dictionary object - just because it contains no variables does not mean it has not been created.

Sub test()

Dim dict As Object
Set dict = CreateObject("scripting.dictionary")

If Not dict Is Nothing Then
    MsgBox "Dict is something!"  '<--- This shows
Else
    MsgBox "Dict is nothing!"
End If

End Sub

However if you declare an object but never create it, it's nothing.

Sub test()

Dim temp As Object

If Not temp Is Nothing Then
    MsgBox "Temp is something!"
Else
    MsgBox "Temp is nothing!" '<---- This shows
End If

End Sub

Well, I solved the problem myself - though I still have no clue why. I decided to isolate the problem by removing all files from the project, then re-adding them and determining that way which file was the source of my trouble. So, one by one I reintroduced files to the project, compiled & cleaned each step of the way... until... I added the last one...

... and everything still worked fine.

I did a compare to the source control of my original .csproj; no real differences. And even when I tried reverting to the previous version of the .csproj, it still worked.

Black magic. If it works, sometimes it's better not to ask why - just accept it and move on...

EDIT: The problem is a recurring one, and I believe I've isolated it to when I have the form designer open of an abstract/generic form at compile time.

Lesson learned: Make sure the Form Designer of any abstract or generic forms or controls is closed before you compile! If not, you have to close VS and reopen!

Always use click if you not dynamically add elements.

live works by adding an event listener to the document root and listens for bubbled up events. An alternative is delegate, which works the same, but binds the event handler to the specified element.
This way, the event has not to bubble up the whole DOM and is caught earlier.

Short solution for preventing user from using context menu, copy and cut in jQuery:

jQuery(document).bind("cut copy contextmenu",function(e){
    e.preventDefault();
});

Also disabling text selection in CSS might come handy:

.noselect {  
    -webkit-touch-callout: none;
    -webkit-user-select: none;
    -khtml-user-select: none;
    -moz-user-select: none;
    -ms-user-select: none;
     user-select: none;
}

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

Passing dictionary as argument it will convert strings which can be converted to float and will leave others

def covertDict_float(data):
        for i in data:
            if data[i].split(".")[0].isdigit():
                try:
                    data[i] = float(data[i])
                except:
                    continue
        return data

Other answers here provide solutions for triggering change detection cycles that will update component's view (which is not same as full re-render).

Full re-render, which would destroy and reinitialize component (calling all lifecycle hooks and rebuilding view) can be done by using ng-template, ng-container and ViewContainerRef in following way:

<div>
  <ng-container #outlet >
  </ng-container>
</div>

<ng-template #content>
  <child></child>
</ng-template>

Then in component having reference to both #outlet and #content we can clear outlets' content and insert another instance of child component:

@ViewChild("outlet", {read: ViewContainerRef}) outletRef: ViewContainerRef;
@ViewChild("content", {read: TemplateRef}) contentRef: TemplateRef<any>;

private rerender() {
    this.outletRef.clear();
    this.outletRef.createEmbeddedView(this.contentRef);
}

Additionally initial content should be inserted on AfterContentInit hook:

ngAfterContentInit() {
    this.outletRef.createEmbeddedView(this.contentRef);
}

Full working solution can be found here https://stackblitz.com/edit/angular-component-rerender .

Here's the painful route:

    SSLContext ctx = null;
    try {
        KeyStore trustStore;
        trustStore = KeyStore.getInstance("JKS");
        trustStore.load(new FileInputStream("C:\\truststore_client"),
                "asdfgh".toCharArray());
        TrustManagerFactory tmf = TrustManagerFactory
                .getInstance("SunX509");
        tmf.init(trustStore);
        ctx = SSLContext.getInstance("SSL");
        ctx.init(null, tmf.getTrustManagers(), null);
    } catch (NoSuchAlgorithmException e1) {
        e1.printStackTrace();
    } catch (KeyStoreException e) {
        e.printStackTrace();
    } catch (CertificateException e) {
        e.printStackTrace();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (KeyManagementException e) {
        e.printStackTrace();
    }
    ClientConfig config = new DefaultClientConfig();
    config.getProperties().put(HTTPSProperties.PROPERTY_HTTPS_PROPERTIES,
            new HTTPSProperties(null, ctx));

    WebResource service = Client.create(config).resource(
            "https://localhost:9999/");
    service.addFilter(new HTTPBasicAuthFilter(username, password));

    // Attempt to view the user's page.
    try {
        service.path("user/" + username).get(String.class);
    } catch (Exception e) {
        e.printStackTrace();
    }

Gotta love those six different caught exceptions :). There are certainly some refactoring to simplify the code a bit. But, I like delfuego's -D options on the VM. I wish there was a javax.net.ssl.trustStore static property that I could just set. Just two lines of code and done. Anyone know where that would be?

This may be too much to ask, but, ideally the keytool would not be used. Instead, the trustedStore would be created dynamically by the code and the cert is added at runtime.

There must be a better answer.

you have have strange characters in your heading # % -- or ,

According to Github API two empty lines are a new paragraph (same as here in stackoverflow)

You can test it with http://prose.io

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>

For me the following simple change worked perfectly

<input type="text" 
        value={props.letter} 
        onChange={event => setTxtLetter(event.target.value)} /> {/* does not work */}

change... value={myPropVal} to... defaultValue={myPropVal}

<input type="text" 
        defaultValue={props.letter} 
        onChange={event => setTxtLetter(event.target.value)} /> {/* Works!! */}

None of the above worked for me, however I had success setting the default at time of instantiation.

JQuery

<script type="text/javascript">
    $(function () {
        var dateNow = new Date();
        $('#datetimepicker').datetimepicker({
            defaultDate:dateNow
        });
    });
</script>

Try this. Here is the code to get the sheet names in order.

private Dictionary<int, string> GetExcelSheetNames(string fileName)
{
    Excel.Application _excel = null;
    Excel.Workbook _workBook = null;
    Dictionary<int, string> excelSheets = new Dictionary<int, string>();
    try
    {
        object missing = Type.Missing;
        object readOnly = true;
        Excel.XlFileFormat.xlWorkbookNormal
        _excel = new Excel.ApplicationClass();
        _excel.Visible = false;
        _workBook = _excel.Workbooks.Open(fileName, 0, readOnly, 5, missing,
            missing, true, Excel.XlPlatform.xlWindows, "\\t", false, false, 0, true, true, missing);
        if (_workBook != null)
        {
            int index = 0;
            foreach (Excel.Worksheet sheet in _workBook.Sheets)
            {
                // Can get sheet names in order they are in workbook
                excelSheets.Add(++index, sheet.Name);
            }
        }
    }
    catch (Exception e)
    {
        return null;
    }
    finally
    {
        if (_excel != null)
        {

            if (_workBook != null)
                _workBook.Close(false, Type.Missing, Type.Missing);
            _excel.Application.Quit();
        }
        _excel = null;
        _workBook = null;
    }
    return excelSheets;
}

Try this...

Calendar calendar = Calendar.getInstance();
String currentDate24Hrs = (String) DateFormat.format(
            "MM/dd/yyyy kk:mm:ss", calendar.getTime());
Log.i("DEBUG_TAG", "24Hrs format date: " + currentDate24Hrs);

Try this: (for more details click here)

image: { flex: 1, height: undefined, width: undefined, resizeMode: 'contain' }

str.split(' ').join('§ §').split('§');

The difference is that ActionEvent is fired when the action is performed on the JCheckBox that is its state is changed either by clicking on it with the mouse or with a space bar or a mnemonic. It does not really listen to change events whether the JCheckBox is selected or deselected.

For instance, if JCheckBox c1 (say) is added to a ButtonGroup. Changing the state of other JCheckBoxes in the ButtonGroup will not fire an ActionEvent on other JCheckBox, instead an ItemEvent is fired.

Final words: An ItemEvent is fired even when the user deselects a check box by selecting another JCheckBox (when in a ButtonGroup), however ActionEvent is not generated like that instead ActionEvent only listens whether an action is performed on the JCheckBox (to which the ActionListener is registered only) or not. It does not know about ButtonGroup and all other selection/deselection stuff.

You can do this by using JQuery.

For example ,

<a href="your URL" id="navigate"> click here </a>

Your JQuery will be,

$(document).ready(function(){

    $('a').on('mousedown', stopNavigate);

    $('a').on('mouseleave', function () {
           $(window).on('beforeunload', function(){
                  return 'Are you sure you want to leave?';
           });
    });
});

function stopNavigate(){    
    $(window).off('beforeunload');
}

And to get the Leave message alert will be,

$(window).on('beforeunload', function(){
      return 'Are you sure you want to leave?';
});

$(window).on('unload', function(){

         logout();

});

This solution works in all browsers and I have tested it.

For Vuejs 2.5 & vue-router 3.0 nothing above worked for me, however after playing around a little bit the following seems to work:

export default new Router({
  mode: 'history',
  hash: false,
  routes: [
  ...
    ,
    { path: '*', redirect: '/' }, // catch all use case
  ],
})

note that you will also need to add the catch-all path.

The EF Core doesn't create DBset for the SQL views automatically in the context calss, we can add them manually as below.

public partial class LocalDBContext : DbContext
{ 

    public LocalDBContext(DbContextOptions<LocalDBContext> options) : base(options)
    {

    }

    public virtual DbSet<YourView> YourView { get; set; }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
        modelBuilder.Entity<YourView>(entity => {
            entity.HasKey(e => e.ID);
            entity.ToTable("YourView");
            entity.Property(e => e.Name).HasMaxLength(50);
        });
    }

}

The sample view is defined as below with few properties

using System;
using System.Collections.Generic;

namespace Project.Entities
{
    public partial class YourView
    {
        public string Name { get; set; }
        public int ID { get; set; }
    }
}

After adding a class for the view and DB set in the context class, you are good to use the view object through your context object in the controller.

EGit Solution

One would expect creating or changing template variables on a project-, workspace-, or environment-basis is a standard Eclipse feature. Sadly, it is not. More so, given that Eclipse plugins can define new variables and templates, there should be plugins out there providing a solution. If they are, they must be hard to find. mmm-TemplateVariable, which is available in the Eclipse Marketplace, is a step in the right direction for Maven users, giving the ability to include version, artifactId, etc. in templates.

Fortunately, EGit, which is an Eclipse tool for Git, provides very flexible means for including many different variables in code templates. The only requirement is that your project uses Git. If you don’t use Git, but are serious about software development, now is the time to learn (Pro Git book). If you are forced to use a legacy version control system, try changing some minds.

Thanks to the efforts of harmsk, EGit 4.0 and above includes the ability to use Git configuration key values in templates. This allows setting template values based on repository settings (project), user settings (account), and/or global settings (workstation).

The following example shows how to set up Eclipse and Git for a multi-user development workstation and use a custom Git configuration key in lieu of ${user} to provide more flexibility. Although the example is based on a Windows 10 installation of Eclipse Mars and Git for Windows, the example is applicable to Linux and OSX running Eclipse and Git using their respective command line tools.

To avoid possible confusion between Git’s user.name configuration key and Java’s user.name system property, a custom Git configuration key – user.author – will be used to provide an author’s name and/or credentials.

Configuring Templates

The format of a Git template variable is as follows

${<name>:git_config(<key>)}

where <name> is any arbitrary variable name and <key> is the Git configuration key whose value should be used. Given that, changing the Comments?Types template to

/**
 * @author ${author:git_config(user.author)}
 *
 * ${tags}
 */

will now attempt to resolve the author’s name from Git’s user.author configuration key. Without any further configuration, any newly created comments will not include a name after @author, since none has been defined yet.

Configuring Git

From the command line

Git System Configuration - This configuration step makes changes to Git’s system-wide configuration applicable to all accounts on the workstation unless overridden by user or repository settings. Because system-wide configurations are part the underlying Git application (e.g. Git for Windows), changes will require Administrator privileges. Run Git Bash, cmd, or PowerShell as Administrator. The following command will set the system-wide author.

git config --system user.author “SET ME IN GLOBAL(USER) or REPOSITORY(LOCAL) SETTINGS”

The purpose of this “author” is to serve as a reminder that it should be set elsewhere. This is particularly useful when new user accounts are being used on the workstation.

To verify this setting, create an empty Java project that uses Git or open an existing Git-based project. Create a class and use Source?Generate Element Comment from the context menu, ALT-SHIFT-J, or start a JavaDoc comment. The resulting @author tag should be followed by the warning.

The remaining configuration changes can be performed without Administrator privileges.

Git Global(User) Configuration - Global, or user, configurations are those associated with a specific user and will override system-wide configurations. These settings apply to all Git-based projects unless overridden by repository settings. If the author name is different due to various project types such as for work, open source contributions, or personal, set the most frequently used here.

git config --global user.author “Mr. John Smith”

Having configured the global value, return to the test project used early and apply a class comment. The@author tag should now show the global setting.

Git Repository(Local) Configuration - Lastly, a repository or local configuration can be used to configure an author for a specific project. Unlike the previous configurations, a repository configuration must be done from within the repository. Using Git Bash, PowerShell, etc. navigate into the test project’s repository.

git config --local user.author “smithy”

Given this, new comments in the test project will use the locally defined author name. Other Git-based projects, will still use the global author name.

From Within Eclipse

The configuration changes above can also be set from within Eclipse through its Preferences: Team?Git-Configuration. Eclipse must be run as Administrator to change system-wide Git configurations.

In Sum

Although this example dealt specifically with the most common issue, that of changing ${user}, this approach can be used for more. However, caution should be exercised not to use Git-defined configuration keys, unless it is specifically intended.

I like Daniel Cerecedo's answer using toJSON() and regex. An even simpler form would be:

var now = new Date();
var regex = /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}).*$/;
var token_array = regex.exec(now.toJSON());
// [ "2017-10-31T02:24:45.868Z", "2017", "10", "31", "02", "24", "45" ]
var myFormat = token_array.slice(1).join('');
// "20171031022445"

The @japf answer above is working fine and in my case I wanted to change the mouse cursor from a Spinning Wheel back to the normal Arrow once the CEF Browser finished loading the page. In case it can help someone, here is the code:

private void Browser_LoadingStateChanged(object sender, CefSharp.LoadingStateChangedEventArgs e) {
   if (!e.IsLoading) {
      // set the cursor back to arrow
      Application.Current.Dispatcher.BeginInvoke(DispatcherPriority.Background,
         new Action(() => Mouse.OverrideCursor = Cursors.Arrow));
   }
}

This doesn't quite yet look like what I want, but I accomplished something like this by stacking nav pills in the leftmost two spans. This is what my app's app/views/layouts/application.html.erb file looks like:

<!DOCTYPE html>
...
  <body>
    <!-- top navigation bar -->
    <div class="navbar navbar-fixed-top">
       ...
    </div>
    <div class="container-fluid">
      <!-- the navigation buttons bar on the left -->
      <div class="sidebar-nav span2"> <!-- we reserve 2 spans out of 12 for this -->
        <ul class="nav nav-pills nav-stacked">
          <li class="<%= current_page?(root_path) ? 'active' : 'inactive' %>">
            <%= link_to "Home", root_path %>
          </li>
          <li class="<%= current_page?(section_a_path) ? 'active' : 'inactive' %>">
            <%= link_to "Section A", section_a_path %>
          </li>
          <li class="<%= current_page?(section_b_path) ? 'active' : 'inactive' %>">
            <%= link_to "Section B", section_b_path %>
          </li>
        </ul>
      </div>
      <div class="container-fluid span10"> <!-- use the remaining 10 spans -->
        <%= flash_messages %>
        <%= yield :layout %> <!-- the content page sees a full 12 spans -->
      </div>
    </div> <!-- class="container-fluid" -->
    ...
  </body>
</html>

Now the stacked pills appear on the top left, below the navbar. When the user clicks on one of them, the corresponding page loads. From the point of view of application.html.erb, that page has the 10 rightmost spans available for it, but from the page's view, it has the full 12 spans available.

The button corresponding to the page currently being displayed is rendered as active, and the others as inactive. Specify the colours for active and inactive buttons in file app/assets/stylesheets/custom.css.scss (in this case, the colour for a disabled state is also defined):

@import "bootstrap";
...
$spray:       #81c9e2;
$grey_light:  #dddddd;
...
.nav-pills {
    .inactive > a, .inactive > a:hover {
        background-color: $spray;
    }
    .disabled > a, .disabled > a:hover {
        background-color: $grey_light;
    }
}

The active pill's colour is not defined, so it appears as the default blue.

File custom.css.scss is included because of the line *= require_tree . in file app/assets/stylesheets/application.css.

Will result always be the floor of the division?

No. The result varies, but variation happens only for negative values.

What is the defined behavior?

To make it clear floor rounds towards negative infinity,while integer division rounds towards zero (truncates)

For positive values they are the same

int integerDivisionResultPositive= 125/100;//= 1
double flooringResultPositive= floor(125.0/100.0);//=1.0

For negative value this is different

int integerDivisionResultNegative= -125/100;//=-1
double flooringResultNegative= floor(-125.0/100.0);//=-2.0

You can use Array#map with Array#find.

arr1.map(obj => arr2.find(o => o.id === obj.id) || obj);

var arr1 = [{_x000D_
    id: '124',_x000D_
    name: 'qqq'_x000D_
}, {_x000D_
    id: '589',_x000D_
    name: 'www'_x000D_
}, {_x000D_
    id: '45',_x000D_
    name: 'eee'_x000D_
}, {_x000D_
    id: '567',_x000D_
    name: 'rrr'_x000D_
}];_x000D_
_x000D_
var arr2 = [{_x000D_
    id: '124',_x000D_
    name: 'ttt'_x000D_
}, {_x000D_
    id: '45',_x000D_
    name: 'yyy'_x000D_
}];_x000D_
_x000D_
var res = arr1.map(obj => arr2.find(o => o.id === obj.id) || obj);_x000D_
_x000D_
console.log(res);

Here, arr2.find(o => o.id === obj.id) will return the element i.e. object from arr2 if the id is found in the arr2. If not, then the same element in arr1 i.e. obj is returned.

This might help you.

Java:

JSONArray arr = new JSONArray(result);
JSONObject jObj = arr.getJSONObject(0);
String date = jObj.getString("NeededString");

Kotlin:

val jsonArray = JSONArray(result)
val jsonObject: JSONObject = jsonArray.getJSONObject(0)
val date= jsonObject.get("NeededString")

• getJSONObject(index). In above example 0 represents index.

You can use stri_detect_fixed function from stringi package

stri_detect_fixed(c("REVERSE223","GENJJS"),"REVERSE")
[1]  TRUE FALSE

A simple solution is to assign color for each class. This way, we can control how each color is for each class. For example:

arr1 = [1, 2, 3, 4, 5]
arr2 = [2, 3, 3, 4, 4]
labl = [0, 1, 1, 0, 0]
color= ['red' if l == 0 else 'green' for l in labl]
plt.scatter(arr1, arr2, color=color)

Did you try InputMethodManager.SHOW_IMPLICIT in first window.

and for hiding in second window use InputMethodManager.HIDE_IMPLICIT_ONLY

EDIT :

If its still not working then probably you are putting it at the wrong place. Override onFinishInflate() and show/hide there.

@override
public void onFinishInflate() {
     /* code to show keyboard on startup */
    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(mUserNameEdit, InputMethodManager.SHOW_IMPLICIT);
}

I'm using a ajax post to run a delete method (happens to be from a visjs timeline but that's not relelvant). This is what I sis:

This is my Index.cshtml

@Scripts.Render("~/bundles/schedule")
@Styles.Render("~/bundles/visjs")
@Html.AntiForgeryToken()

<!-- div to attach schedule to -->
<div id='schedule'></div>

<!-- div to attach popups to -->
<div id='dialog-popup'></div>

All I added here was @Html.AntiForgeryToken() to make the token appear in the page

Then in my ajax post I used:

$.ajax(
    {
        type: 'POST',
        url: '/ScheduleWorks/Delete/' + item.id,
        data: {
            '__RequestVerificationToken': 
            $("input[name='__RequestVerificationToken']").val()
              }
     }
);

Which adds the token value, scraped off the page, to the fields posted

Before this I tried putting the value in the headers but I got the same error

Feel free to post improvements. This certainly seems to be a simple approach that I can understand

Let me explain why you do you got this error "Bus error: 10"

char *str1 = "First string";
// for this statement the memory will be allocated into the CODE/TEXT segment which is READ-ONLY

char *str2 = "Second string";
// for this statement the memory will be allocated into the CODE/TEXT segment which is READ-ONLY

strcpy(str1, str2);
// This function will copy the content from str2 into str1, this is not possible because you are try to perform READ WRITE operation inside the READ-ONLY segment.Which was the root cause 

If you want to perform string manipulation use automatic variables(STACK segment) or dynamic variables(HEAP segment)

Vasanth

class of my button is "input-addon btn btn-default fileinput-exists"

below code helped me

document.querySelector('.input-addon.btn.btn-default.fileinput-exists').click();

but I want to click second button, I have two buttons in my screen so I used querySelectorAll

var elem = document.querySelectorAll('.input-addon.btn.btn-default.fileinput-exists');
                elem[1].click();

here elem[1] is the second button object that I want to click.

Writing a null character to the first character does just that. If you treat it as a string, code obeying the null termination character will treat it as a null string, but that is not the same as clearing the data. If you want to actually clear the data you'll need to use memset.

Using jquery

var favicon = $("link[rel='shortcut icon']").attr("href") ||
              $("link[rel='icon']").attr("href") || "";

Usually, this problem resolve with using the modulo of a number in a loop or convert a number to a string. For convert a number to a string, you may can use the function itoa, so considering the variant with the modulo of a number in a loop.

In my case, the solution was to make every directory in the directory path readable and accessible by mysql (chmod a+rx). The directory was still specified by its relative path in the command line.

chmod a+rx /tmp
chmod a+rx /tmp/migration
etc.

Starting with Swift 3, it is

for (index, element) in list.enumerated() {
  print("Item \(index): \(element)")
}

Because ( is special in regex, you should escape it \( when matching. However, depending on what language you are using, you can easily match ( with string methods like index() or other methods that enable you to find at what position the ( is in. Sometimes, there's no need to use regex.

PowerShell Core (v6+) now has a Remove-Service cmdlet.

I don't know about plans to back-port it to Windows PowerShell, where it is not available as of v5.1.

Example:

# PowerShell *Core* only (v6+)
Remove-Service someservice

Note that invocation fails if the service doesn't exist, so to only remove it if it currently exists, you could do:

# PowerShell *Core* only (v6+)
$name = 'someservice'
if (Get-Service $name -ErrorAction Ignore) {
  Remove-Service $name
}

In other words...

IDE Even your notepad is an IDE. Every software you write/compile code with is an IDE.

Library A bunch of code which simplifies functions/methods for quick use.

API A programming interface for functions/configuration which you work with, its usage is often documented.

SDK Extras and/or for development/testing purposes.

ToolKit Tiny apps for quick use, often GUIs.

GUI Apps with a graphical interface, requires no knowledge of programming unlike APIs.

Framework Bunch of APIs/huge Library/Snippets wrapped in a namespace/or encapsulated from outer scope for compact handling without conflicts with other code.

MVC A design pattern separated in Models, Views and Controllers for huge applications. They are not dependent on each other and can be changed/improved/replaced without to take care of other code.

Example:

<sup>Car (Model)
The object that is being presented.
Example in IT: A HTML form.

Camera (View)
Something that is able to see the object(car).
Example in IT: Browser that renders a website with the form.

Driver (Controller)
Someone who drives that car.
Example in IT: Functions which handle form data that's being submitted.</sup>

Snippets Small codes of only a few lines, may not be even complete but worth for a quick share.

Plug-ins Exclusive functions for specified frameworks/APIs/libraries only.

Add-ons Additional modules or services for specific GUIs.

Note that you can still do:

s[0] = 'h';
s[1] = 'e';
s[2] = 'l';
s[3] = 'l';
s[4] = 'o';
s[5] = '\0';

Just need to add a space:

.area2 .item
{
    ...
}

Here is a more developed version of the accepted answer that addresses two common needs:

• Collecting user input repeatedly until an exit value has been entered
• Dealing with invalid input values (non-integers in this example)

Code

package inputTest;

import java.util.Scanner;
import java.util.InputMismatchException;

public class InputTest {
    public static void main(String args[]) {
        Scanner reader = new Scanner(System.in);
        System.out.println("Please enter integers. Type 0 to exit.");

        boolean done = false;
        while (!done) {
            System.out.print("Enter an integer: ");
            try {
                int n = reader.nextInt();
                if (n == 0) {
                    done = true;
                }
                else {
                    // do something with the input
                    System.out.println("\tThe number entered was: " + n);
                }
            }
            catch (InputMismatchException e) {
                System.out.println("\tInvalid input type (must be an integer)");
                reader.nextLine();  // Clear invalid input from scanner buffer.
            }
        }
        System.out.println("Exiting...");
        reader.close();
    }
}

Example

Please enter integers. Type 0 to exit.
Enter an integer: 12
    The number entered was: 12
Enter an integer: -56
    The number entered was: -56
Enter an integer: 4.2
    Invalid input type (must be an integer)
Enter an integer: but i hate integers
    Invalid input type (must be an integer)
Enter an integer: 3
    The number entered was: 3
Enter an integer: 0
Exiting...

Note that without nextLine(), the bad input will trigger the same exception repeatedly in an infinite loop. You might want to use next() instead depending on the circumstance, but know that input like this has spaces will generate multiple exceptions.

I tracked the solution down to Interface Builder's insistence that springs cannot be changed on a view that has the simulated screen elements turned on (status bar, etc.). Since the springs were off for the main view, that view could not change size and hence was scrolled down in its entirety when the in-call bar appeared.

Turning the simulated features off, then resizing the view and setting the springs correctly caused the animation to occur and my method to be called.

An extra problem in debugging this is that the simulator quits the app when the in-call status is toggled via the menu. Quit app = no debugger.

Have you tried DevDefined.OAuth?

I have used it to secure my WebApi with 2-Legged OAuth. I have also successfully tested it with PHP clients.

It's quite easy to add support for OAuth using this library. Here's how you can implement the provider for ASP.NET MVC Web API:

1) Get the source code of DevDefined.OAuth: https://github.com/bittercoder/DevDefined.OAuth - the newest version allows for OAuthContextBuilder extensibility.

2) Build the library and reference it in your Web API project.

3) Create a custom context builder to support building a context from HttpRequestMessage:

using System;
using System.Collections.Generic;
using System.Collections.Specialized;
using System.Diagnostics.CodeAnalysis;
using System.Linq;
using System.Net.Http;
using System.Web;

using DevDefined.OAuth.Framework;

public class WebApiOAuthContextBuilder : OAuthContextBuilder
{
    public WebApiOAuthContextBuilder()
        : base(UriAdjuster)
    {
    }

    public IOAuthContext FromHttpRequest(HttpRequestMessage request)
    {
        var context = new OAuthContext
            {
                RawUri = this.CleanUri(request.RequestUri), 
                Cookies = this.CollectCookies(request), 
                Headers = ExtractHeaders(request), 
                RequestMethod = request.Method.ToString(), 
                QueryParameters = request.GetQueryNameValuePairs()
                    .ToNameValueCollection(), 
            };

        if (request.Content != null)
        {
            var contentResult = request.Content.ReadAsByteArrayAsync();
            context.RawContent = contentResult.Result;

            try
            {
                // the following line can result in a NullReferenceException
                var contentType = 
                    request.Content.Headers.ContentType.MediaType;
                context.RawContentType = contentType;

                if (contentType.ToLower()
                    .Contains("application/x-www-form-urlencoded"))
                {
                    var stringContentResult = request.Content
                        .ReadAsStringAsync();
                    context.FormEncodedParameters = 
                        HttpUtility.ParseQueryString(stringContentResult.Result);
                }
            }
            catch (NullReferenceException)
            {
            }
        }

        this.ParseAuthorizationHeader(context.Headers, context);

        return context;
    }

    protected static NameValueCollection ExtractHeaders(
        HttpRequestMessage request)
    {
        var result = new NameValueCollection();

        foreach (var header in request.Headers)
        {
            var values = header.Value.ToArray();
            var value = string.Empty;

            if (values.Length > 0)
            {
                value = values[0];
            }

            result.Add(header.Key, value);
        }

        return result;
    }

    protected NameValueCollection CollectCookies(
        HttpRequestMessage request)
    {
        IEnumerable<string> values;

        if (!request.Headers.TryGetValues("Set-Cookie", out values))
        {
            return new NameValueCollection();
        }

        var header = values.FirstOrDefault();

        return this.CollectCookiesFromHeaderString(header);
    }

    /// <summary>
    /// Adjust the URI to match the RFC specification (no query string!!).
    /// </summary>
    /// <param name="uri">
    /// The original URI. 
    /// </param>
    /// <returns>
    /// The adjusted URI. 
    /// </returns>
    private static Uri UriAdjuster(Uri uri)
    {
        return
            new Uri(
                string.Format(
                    "{0}://{1}{2}{3}", 
                    uri.Scheme, 
                    uri.Host, 
                    uri.IsDefaultPort ?
                        string.Empty :
                        string.Format(":{0}", uri.Port), 
                    uri.AbsolutePath));
    }
}

4) Use this tutorial for creating an OAuth provider: http://code.google.com/p/devdefined-tools/wiki/OAuthProvider. In the last step (Accessing Protected Resource Example) you can use this code in your AuthorizationFilterAttribute attribute:

public override void OnAuthorization(HttpActionContext actionContext)
{
    // the only change I made is use the custom context builder from step 3:
    OAuthContext context = 
        new WebApiOAuthContextBuilder().FromHttpRequest(actionContext.Request);

    try
    {
        provider.AccessProtectedResourceRequest(context);

        // do nothing here
    }
    catch (OAuthException authEx)
    {
        // the OAuthException's Report property is of the type "OAuthProblemReport", it's ToString()
        // implementation is overloaded to return a problem report string as per
        // the error reporting OAuth extension: http://wiki.oauth.net/ProblemReporting
        actionContext.Response = new HttpResponseMessage(HttpStatusCode.Unauthorized)
            {
               RequestMessage = request, ReasonPhrase = authEx.Report.ToString()
            };
    }
}

I have implemented my own provider so I haven't tested the above code (except of course the WebApiOAuthContextBuilder which I'm using in my provider) but it should work fine.

you need to use backslash before ". like \"

From the doc here you can see that

A character preceded by a backslash ( \ ) is an escape sequence and has special meaning to the compiler.

and " (double quote) is a escacpe sequence

When an escape sequence is encountered in a print statement, the compiler interprets it accordingly. For example, if you want to put quotes within quotes you must use the escape sequence, \", on the interior quotes. To print the sentence

She said "Hello!" to me.

you would write

System.out.println("She said \"Hello!\" to me.");

jQuery(document).on('click', 'video', function(){
        if (this.paused) {
            this.play();
        } else {
            this.pause();
        }
});

My question is when should a use a double and when should I use a decimal type?

decimal for when you work with values in the range of 10^(+/-28) and where you have expectations about the behaviour based on base 10 representations - basically money.

double for when you need relative accuracy (i.e. losing precision in the trailing digits on large values is not a problem) across wildly different magnitudes - double covers more than 10^(+/-300). Scientific calculations are the best example here.

which type is suitable for money computations?

decimal, decimal, decimal

Accept no substitutes.

The most important factor is that double, being implemented as a binary fraction, cannot accurately represent many decimal fractions (like 0.1) at all and its overall number of digits is smaller since it is 64-bit wide vs. 128-bit for decimal. Finally, financial applications often have to follow specific rounding modes (sometimes mandated by law). decimal supports these; double does not.

You can use the following command:

git reset -- my-file.txt

which will update both the working copy of my-file.txt when added.

Some scenarios don't always allow developers to switch scripting language.

My preference is definitely for JavaScript (and I have used it in new projects). However, maintaining older projects is still required and necessary. Unfortunately, these are written in VBScript.

So even though this solution doesn't offer true "try/catch" functionaility, the result is the same, and that's good enough for me to get the job done.

You can try this with Color.FromArgb:

Random rnd = new Random();
lbl.ForeColor = Color.FromArgb(rnd.Next(255), rnd.Next(255), rnd.Next(255));

If you see table class it has border-spacing: 2px; You could override table class in your css and set its border-spacing: 0px!important in table; I did it like

table {
      border-collapse: separate;
      white-space: normal;
      line-height: normal;
      font-weight: normal;
      font-size: medium;
      font-style: normal;
      color: -internal-quirk-inherit;
      text-align: start;
      border-spacing: 0px!important;
      font-variant: normal;   }

It saved my day.Hope it would be of help. Thanks.

This will do the trick :-

new Date().valueOf() 

You simply need to install Crystal Report Report Run Time downloads on Deployment Server. If problem still appears, then place check asp_client folder in your project main folder.

You have two typing errors in your code:

 struct timeval,

should be

 struct timeval

and after the printf() parenthesis you need a semicolon.

Also, depending on the compiler, so simple a cycle might just be optimized out, giving you a time of 0 microseconds whatever you do.

Finally, the time calculation is wrong. You only take into accounts the seconds, ignoring the microseconds. You need to get the difference between seconds, multiply by one million, then add "after" tv_usec and subtract "before" tv_usec. You gain nothing by casting an integer number of seconds to a float.

I'd suggest checking out the man page for struct timeval.

This is the code:

#include <stdio.h>
#include <sys/time.h>

int main (int argc, char** argv) {
    struct timeval tvalBefore, tvalAfter;  // removed comma

    gettimeofday (&tvalBefore, NULL);
    int i =0;
    while ( i < 10000) {
        i ++;
    }

    gettimeofday (&tvalAfter, NULL);

    // Changed format to long int (%ld), changed time calculation

    printf("Time in microseconds: %ld microseconds\n",
            ((tvalAfter.tv_sec - tvalBefore.tv_sec)*1000000L
           +tvalAfter.tv_usec) - tvalBefore.tv_usec
          ); // Added semicolon
    return 0;
}

I think you can use onAttachFragment event may be useful to catch which fragment is active.

@Override
public void onAttachFragment(Fragment fragment) {
    // TODO Auto-generated method stub
    super.onAttachFragment(fragment);

    Toast.makeText(getApplicationContext(), String.valueOf(fragment.getId()), Toast.LENGTH_SHORT).show();

}

This will do it recursively for you:

find /path/to/base/dir/* -type d -ctime +10 -exec rm -rf {} \;

Explanation:

• find: the unix command for finding files / directories / links etc.
• /path/to/base/dir: the directory to start your search in.
• -type d: only find directories
• -ctime +10: only consider the ones with modification time older than 10 days
• -exec ... \;: for each such result found, do the following command in ...
• rm -rf {}: recursively force remove the directory; the {} part is where the find result gets substituted into from the previous part.

Alternatively, use:

find /path/to/base/dir/* -type d -ctime +10 | xargs rm -rf

Which is a bit more efficient, because it amounts to:

rm -rf dir1 dir2 dir3 ...

as opposed to:

rm -rf dir1; rm -rf dir2; rm -rf dir3; ...

as in the -exec method.

With modern versions of find, you can replace the ; with + and it will do the equivalent of the xargs call for you, passing as many files as will fit on each exec system call:

find . -type d -ctime +10 -exec rm -rf {} +

The biggest clue is the rows are all being returned on one line. This indicates line terminators are being ignored or are not present.

You can specify the line terminator for csv_reader. If you are on a mac the lines created will end with \rrather than the linux standard \n or better still the suspenders and belt approach of windows with \r\n.

pandas.read_csv(filename, sep='\t', lineterminator='\r')

You could also open all your data using the codecs package. This may increase robustness at the expense of document loading speed.

import codecs

doc = codecs.open('document','rU','UTF-16') #open for reading with "universal" type set

df = pandas.read_csv(doc, sep='\t')

You can use Expressions windows: while debugging, menu window -> Show View -> Expressions, then it has place to type variables of which you need to see contents

The newline character (\n) can be used to add a newline into a markdown file programmatically. For example, it is possible to do like this in python:

with open("file_name.md", "w") as file:
   file.write("Some text")
   file.write("\n")
   file.write("Some other text")

Create custom TextWatcher subclass:

public class CustomWatcher implements TextWatcher {

    private boolean mWasEdited = false;

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable s) {

        if (mWasEdited){

            mWasEdited = false;
            return;
        }

        // get entered value (if required)
        String enteredValue  = s.toString();

        String newValue = "new value";

        // don't get trap into infinite loop
        mWasEdited = true;
        // just replace entered value with whatever you want
        s.replace(0, s.length(), newValue);

    }
}

Set listener for your EditText:

mTargetEditText.addTextChangedListener(new CustomWatcher());

enter code here IN DATAFRAME:

val p=spark.read.format("csv").options(Map("header"->"true","delimiter"->"^")).load("filename.csv")

After setting the path with the Maven bin location close the prompt window and restart it. Use the echo %path% command to make sure the path is set with Maven variables then run the command mvn -version. Somehow if the path is set when the prompt window is running it does not pick the new variables.

In case you want to be fully bomb prove, this is what I would advice:

@('Apples', 'Apples ', 'APPLES', 'Banana') | 
    Sort-Object -Property @{Expression={$_.Trim()}} -Unique

Output:

Apples
Banana

This uses the Property parameter to first Trim() the strings, so extra spaces are removed and then selects only the -Unique values.

data attributes are commonly used for a variety of interactions. Typically via javascript. They do not affect anything regarding site behavior and stand as a convenient method to pass data for whatever purpose needed. Here is an article that may clear things up:

http://ejohn.org/blog/html-5-data-attributes/

You can create a data attribute by prefixing data- to any standard attribute safe string (alphanumeric with no spaces or special characters). For example, data-id or in this case data-reactid

maybe you benefit from converting it to JSON string

String jsonString = new com.google.gson.Gson().toJson(myObject);

in my case, I wanted to add an object to the response headers but you cant add objects to the headers,

so to solve this I convert my object to JSON string and in the client side I will return that string to JSON again

Check Enable Live Templates and leave the cursor at the position desired and click Apply then OK

My preferred method for reloading the same page is $_SERVER['PHP_SELF']

header('Location: '.$_SERVER['PHP_SELF']);
die;

Don't forget to die or exit after your header();

Edit: (Thanks @RafaelBarros )

If the query string is also necessary, use

header('Location:'.$_SERVER['PHP_SELF'].'?'.$_SERVER['QUERY_STRING']);
die;

Edit: (thanks @HugoDelsing)

When htaccess url manipulation is in play the value of $_SERVER['PHP_SELF'] may take you to the wrong place. In that case the correct url data will be in $_SERVER['REQUEST_URI'] for your redirect, which can look like Nabil's answer below:

header("Location: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
exit;

You can also use $_SERVER[REQUEST_URI] to assign the correct value to $_SERVER['PHP_SELF'] if desired. This can help if you use a redirect function heavily and you don't want to change it. Just set the correct vale in your request handler like this:

$_SERVER['PHP_SELF'] = 'https://sample.com/controller/etc';

Most terse version I can think of

Len(Trim(TextBox1.Value)) = 0

If you need to do this multiple times, wrap it in a function

Public Function HasContent(text_box as Object) as Boolean
    HasContent = (Len(Trim(text_box.Value)) > 0)
End Function

Usage

If HasContent(TextBox1) Then
    ' ...

I don't know why you think there's no constructor. See the API.

From the SQL Server 2017 official documentation:

SELECT DATEADD(day, 360, GETDATE());

If you would like to remove the time part of the GETDATE function, you can do:

SELECT DATEADD(day, 360, CAST(GETDATE() AS DATE));

As long as you still have access to the mac which was used to generate the original distribution certificate it's very simple.

Just use that mac's Keychain Access application to export both the certificate and the private key. Select both using shift or command and right click to export to a .p12 file.

Attached a screenshot to make it very clear.

On your mac, import that .p12 file and you are good to go (just make sure you have a valid provisioning profile).

Typically for a use case which involves a sequence of pages and in the final stage or page we post the data to the server. In this scenario we need to maintain the state. In the below snippet we maintain the state on the client side

As mentioned in the above post. The session is created using the factory recipe.

Client side session can be maintained using the value provider recipe as well.

Please refer to my post for the complete details. session-tracking-in-angularjs

Let's take an example of a shopping cart which we need to maintain across various pages / angularjs controller.

In typical shopping cart we buy products on various product / category pages and keep updating the cart. Here are the steps.

Here we create the custom injectable service having a cart inside using the "value provider recipe".

'use strict';
function Cart() {
    return {
        'cartId': '',
        'cartItem': []
    };
}
// custom service maintains the cart along with its behavior to clear itself , create new , delete Item or update cart 

app.value('sessionService', {
    cart: new Cart(),
    clear: function () {
        this.cart = new Cart();
        // mechanism to create the cart id 
        this.cart.cartId = 1;
    },
    save: function (session) {
        this.cart = session.cart;
    },
    updateCart: function (productId, productQty) {
        this.cart.cartItem.push({
            'productId': productId,
            'productQty': productQty
        });
    },
    //deleteItem and other cart operations function goes here...
});

I got this working by installing the various plugins below.

Most of the time things just import by themselves as soon as I type the class name. Alternatively, a lightbulb appears that you can click on. Or you can push F1, and type "import..." and there are various options there too. I kinda use all of them. Also F1 Implement for implementing an interface is helpful, but doesn't always work.

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

Use this

jQuery("input.second").trigger("click");

In order to get around the Enable Macro prompt I suggest

Application.AutomationSecurity = msoAutomationSecurityForceDisable

Be sure to return it to default when you are done

Application.AutomationSecurity = msoAutomationSecurityLow

A reminder that the .SaveAs function contains all optional arguments.I recommend removing CreatBackup:= False as it is not necessary.

The most interesting way I think is to create an object of the workbook and access the .SaveAs property that way. I have not tested it but you are never using Workbooks.Open rendering Application.AutomationSecurity inapplicable. Possibly saving resources and time as well.

That said I was able to execute the following without any notifications on Excel 2013 windows 10.

    Option Explicit

    Sub Convert()

    OptimizeVBA (True)  
    'function to set all the things you want to set, but hate keying in

    Application.AutomationSecurity = msoAutomationSecurityForceDisable  
    'this should stop those pesky enable prompts

    ChDir "F:\VBA Macros\Stack Overflow Questions\When changing type xlsm to 
    xlsx stop popup"

    Workbooks.Open ("Book1.xlsm")

    ActiveWorkbook.SaveAs Filename:= _
    "F:\VBA Macros\Stack Overflow Questions\When changing type xlsm to xlsx_ 
    stop popup\Book1.xlsx" _
    , FileFormat:=xlOpenXMLWorkbook

    ActiveWorkbook.Close

    Application.AutomationSecurity = msoAutomationSecurityLow 
    'make sure you set this up when done

    Kill ("F:\VBA Macros\Stack Overflow Questions\When changing type xlsm_ 
    to xlsx stop popup\Book1.xlsx") 'clean up

    OptimizeVBA (False)
    End Sub


    Function OptimizeVBA(ByRef Status As Boolean)

    If Status = True Then
        Application.ScreenUpdating = False
        Application.Calculation = xlCalculationManual
        Application.DisplayAlerts = False
        Application.EnableEvents = False
    Else
        Application.ScreenUpdating = True
        Application.Calculation = xlCalculationAutomatic
        Application.DisplayAlerts = True
        Application.EnableEvents = True
    End If

    End Function

For ListView or GridView there is an another difference, when visibility initially set to

INVISIBLE:

Adapter's getView() function called

GONE:

Adapter's getView() function didn't call, thus preventing views to load, when it is unnecessary

Newtonsoft is faster than java script serializer. ... this one depends on the Newtonsoft NuGet package, which is popular and better than the default serializer.

one line code solution.

var myclass = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(Jsonstring);

Myclass oMyclass = Newtonsoft.Json.JsonConvert.DeserializeObject<Myclass>(Jsonstring);

You separate the values you want to return by commas:

def get_name():
   # you code
   return first_name, last_name

The commas indicate it's a tuple, so you could wrap your values by parentheses:

return (first_name, last_name)

Then when you call the function you a) save all values to one variable as a tuple, or b) separate your variable names by commas

name = get_name() # this is a tuple
first_name, last_name = get_name()
(first_name, last_name) = get_name() # You can put parentheses, but I find it ugly

To get the specific tag code try to create a new branch add get the tag code in it. I have done it by command : $git checkout -b newBranchName tagName

Java didn't provide multiple inheritance.
When you say A extends B then it means that A extends B and B extends Object.
It doesn't mean A extends B, Object.

class A extends Object
class B extends A

It most likely means the hostname can't be resolved.

import socket
socket.getaddrinfo('localhost', 8080)

If it doesn't work there, it's not going to work in the Bottle example. You can try '127.0.0.1' instead of 'localhost' in case that's the problem.

Thank You everybody for the interesting posts!

I modified the code because in my case I needed

• a personalized join predicate
• a personalized union distinct comparer

For the ones interested this is my modified code (in VB, sorry)

I've used this. Add a script reference to jquery on the Report.aspx page. Use the following to link up JQuery to the microsoft events. Used a little bit of Eric's suggestion for setting the overflow.

$(document).ready(function () {
    if (navigator.userAgent.toLowerCase().indexOf("webkit") >= 0) {        
        Sys.Application.add_init(function () {
            var prm = Sys.WebForms.PageRequestManager.getInstance();
            if (!prm.get_isInAsyncPostBack()) {
                prm.add_endRequest(function () {
                    var divs = $('table[id*=_fixedTable] > tbody > tr:last > td:last > div')
                    divs.each(function (idx, element) {
                        $(element).css('overflow', 'visible');
                    });
                });
            }
        });
    }
});

There are basically two ways to address it:

1. (Recommended) Use regular expression syntax supported by grep(1). Modern grep(1) supports two forms of POSIX 1003.2 regex syntax: basic (obsolete) REs, and modern REs. Syntax is described in details on re_format(7) and regex(7) man pages which are part of BSD and Linux systems respectively. The GNU grep(1) also supports Perl-compatible REs as provided by the pcre(3) library.

   In regex language the tab symbol is usually encoded by \t atom. The atom is supported by BSD extended regular expressions (egrep, grep -E on BSD compatible system), as well as Perl-compatible REs (pcregrep, GNU grep -P).

   Both basic regular expressions and Linux extended REs apparently have no support for the \t. Please consult UNIX utility man page to know which regex language it supports (hence the difference between sed(1), awk(1), and pcregrep(1) regular expressions).

   Therefore, on Linux:

   $ grep -P '\t' FILE ...
   

   On BSD alike system:

   $ egrep '\t' FILE ...
   $ grep -E '\t' FILE ...
   

2. Pass the tab character into pattern. This is straightforward when you edit a script file:

   # no tabs for Python please!
   grep -q '   ' *.py && exit 1
   

   However, when working in an interactive shell you may need to rely on shell and terminal capabilities to type the proper symbol into the line. On most terminals this can be done through Ctrl+V key combination which instructs terminal to treat the next input character literally (the V is for "verbatim"):

   $ grep '<Ctrl>+<V><TAB>' FILE ...
   

   Some shells may offer advanced support for command typesetting. Such, in bash(1) words of the form $'string' are treated specially:

   bash$ grep $'\t' FILE ...
   

   Please note though, while being nice in a command line this may produce compatibility issues when the script will be moved to another platform. Also, be careful with quotes when using the specials, please consult bash(1) for details.

   For Bourne shell (and not only) the same behaviour may be emulated using command substitution augmented by printf(1) to construct proper regex:

   $ grep "`printf '\t'`" FILE ...
   

Marco's answer above is correct, but just to expand on the question of "under what context"...

frame - this is the property you most often use for normal iPhone applications. most controls will be laid out relative to the "containing" control so the frame.origin will directly correspond to where the control needs to display, and frame.size will determine how big to make the control.

center - this is the property you will likely focus on for sprite based games and animations where movement or scaling may occur. By default animation and rotation will be based on the center of the UIView. It rarely makes sense to try and manage such objects by the frame property.

bounds - this property is not a positioning property, but defines the drawable area of the UIView "relative" to the frame. By default this property is usually (0, 0, width, height). Changing this property will allow you to draw outside of the frame or restrict drawing to a smaller area within the frame. A good discussion of this can be found at the link below. It is uncommon for this property to be manipulated unless there is specific need to adjust the drawing region. The only exception is that most programs will use the [[UIScreen mainScreen] bounds] on startup to determine the visible area for the application and setup their initial UIView's frame accordingly.

Why is there an frame rectangle and an bounds rectangle in an UIView?

Hopefully this helps clarify the circumstances where each property might get used.

Continuous Integration

I Agree with your university's definition. Continuous Integration is a strategy for how a developer can integrate code to the mainline continuously - as opposed to frequently.

You might claim that it's merely a branching strategy in your version control system.

It has to do with the size of the tasks you assign to a developer; If a task is estimated to take 4-5 man-days then the developer will have no incitement to deliver anything for the next 4-5 days, because he's not done with anything - yet.

So size matters:

small task = continuous integration
big task   = frequent integration

The ideal task size is not bigger than a day's work. This way a developer will naturally have at least one integration per day.

Continuous Delivery

There are basically three schools within Continuous Delivery:

Continuous Delivery is a natural extension of Continuous Integration

This school, looks at the Addison-Wesley "Martin Fowler" signature series and makes the assumption that since the 2007 release was called "Continuous Integration" and the one that followed in 2011 was called "Continuous Delivery" they are probably volume 1+2 of the same conceptual idea that has to do with continuous something.

Continuous Delivery has to do with Agile Software Development

This school takes off-set in the idea that Continuous Delivery is all about being able to support the principles in the agile movement, not just as a conceptual idea or a letter of intent but for real - in real life.

Taking offset in the first principle in the Agile Manifesto where the term "continuous delivery" is actually used for the first time:

Our highest priority is to satisfy the customer through early and continuous delivery of valuable software.

This school claims that "Continuous Delivery" is a paradigm that embraces everything required to implement an automated verification of your "definition of done".

This school accepts that "Continuous Delivery" and the buzz word or megatrend "DevOps" are flip sides of the same coin, in the sense that they both try to embrace or encapsulate this new paradigm or approach and not just a technique.

Continuous Delivery is a synonym to Continuous Deployment

The third school advocates that Continuous Deployment and Continuous Delivery can be used interchangeably to mean the same thing.

When something is ready in the hands of the developers, it's immediately delivered to the end-users, which in most cases will mean that it should be deployed to the production environment. Hence "Deploy" and "Deliver" means the same.

Which school to join

Your university clearly joined the first school and claims that we're referring to volume 1+2 of the same publication series. My opinion is that this is a misuse of the term Continuous Delivery.

I personally advocate for the understanding that Continuous Delivery is related to implementing a real-life support for the ideas and concepts stated by the agile movement. So I joined the school that says the term embraces a whole paradigm - like "DevOps".

The school that uses delivery as a synonym to deploy is mostly advocated by tool vendors who create deployment consoles, trying to get a bit of hype from the more widespread use of the term Continuous Delivery.

Continuous Deployment

The focus on Continuous Deployment is mostly relevant in domains where the end user's access to software updates relies on the update of some centralized source for this information and where this centralized source is not always easy to update because it's monolithic or has (too) high coherence by nature (web, SOA, Databases etc.).

For a lot of domains that produces software where there is no centralized source of information (devices, consumer products, client installations etc.) or where the centralized source for information is easy to update (app stores artifact management systems, Open Source repositories etc.), there is almost no hype about the term Continuous Deployment at all. They just deploy; it's not a big thing - it's not a pain that requires special focus.

The fact that Continuous Deployment is not something that is generically interesting to everyone is also an argument that the school that claims that "delivery" and "deploy" are synonyms got it all wrong. Because Continuous Delivery actually makes perfectly good sense to everyone - even if you are doing embedded software in devices or releasing Open Source plugins for a framework.

Your university's definition that Continuous Deployment is a natural next step of Continuous Delivery implicitly assumes that every delivery that is QA'ed should go become available to the end-users immediately, is closer to the definition that my tribe use to describe the term "Continous Release", which, in turn, is another concept that doesn't generically makes sense to everyone either.

A release can be a very strategic or political thing and there is no reason to assume that everybody would want to do this all the time (unless they are an online bookstore a streaming service type of company). Nevertheless, companies that don't blindly release everything all the time may have any number of reasons why they would want to be masters of deployment anyway, so they too do Continuous Deployment. Not of release to production, but of release-candidates to production-like environments.

Again I believe your university got it wrong. They are mistaking "Continuous Deployment" for "Continuous Release".

Continuous deployment is simply the discipline of continuously being able to move the result of a development process to a production-like environment where functional testing can be executed in full scale.

The Continuous Delivery Storyline

In the picture it all comes alive:

The Continuous Integration process is the first two actions in the state-transition diagram. which - if successful - kicks off the Continuous Delivery pipeline that implements the definition of done. Deployment is just one of the many actions that will have to be done continuously in this pipeline. Ideally, the process is automated from the point where the developer commits to the VCS to the point where the pipeline has confirmed that we have a valid release candidate.

Although there are some useful algorithmic explanations here, I think it may help to add some simple 'real life' reasoning as to why it works this way, which I have found useful when introducing the subject to young newcomers:

With something like 'range(1,10)' confusion can arise from thinking that pair of parameters represents the "start and end".

It is actually start and "stop".

Now, if it were the "end" value then, yes, you might expect that number would be included as the final entry in the sequence. But it is not the "end".

Others mistakenly call that parameter "count" because if you only ever use 'range(n)' then it does, of course, iterate 'n' times. This logic breaks down when you add the start parameter.

So the key point is to remember its name: "stop". That means it is the point at which, when reached, iteration will stop immediately. Not after that point.

So, while "start" does indeed represent the first value to be included, on reaching the "stop" value it 'breaks' rather than continuing to process 'that one as well' before stopping.

One analogy that I have used in explaining this to kids is that, ironically, it is better behaved than kids! It doesn't stop after it supposed to - it stops immediately without finishing what it was doing. (They get this ;) )

Another analogy - when you drive a car you don't pass a stop/yield/'give way' sign and end up with it sitting somewhere next to, or behind, your car. Technically you still haven't reached it when you do stop. It is not included in the 'things you passed on your journey'.

I hope some of that helps in explaining to Pythonitos/Pythonitas!

Change the last line to

q + theme(axis.text.x = element_text(angle = 90, vjust = 0.5, hjust=1))

By default, the axes are aligned at the center of the text, even when rotated. When you rotate +/- 90 degrees, you usually want it to be aligned at the edge instead:

SWIFT 4:

1. Create an @IBAction with segue inside controller you want to unwind to:

    @IBAction func unwindToVC(segue: UIStoryboardSegue) {

    }

2. In the storyboard, from the controller you want to segue (unwind) from ctrl+drag from the controller sign to exit sign and choose method you created earlier:

3. Now you can notice that in document outline you have new line with title "Unwind segue....". Now you should click on this line and open attribute inspector to set identifier (in my case unwindSegueIdentifier).

4. You're almost done! Now you need to open view controller you wish to unwind from and create some method that will perform segue. For example you can add button, connect it with code with @IBAction, after that inside this IBAction add perfromSegue(withIdentifier:sender:) method:

     @IBAction func unwindToSomeVCWithSegue(_ sender: UIButton) {
         performSegue(withIdentifier: "unwindSegueIdentifier", sender: nil)
     }

So that is all you have to do!

or alternatively you could not bother coding for it and use the 'conditional formatting' function in Excel which will set the background colour and font colour based on cell value.

There are only two variables here so set the default to yellow and then overwrite when the value is greater than or less than your threshold values.

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

When it comes to a range of commits, cherry-picking is was not practical.

As mentioned below by Keith Kim, Git 1.7.2+ introduced the ability to cherry-pick a range of commits (but you still need to be aware of the consequence of cherry-picking for future merge)

git cherry-pick" learned to pick a range of commits
(e.g. "cherry-pick A..B" and "cherry-pick --stdin"), so did "git revert"; these do not support the nicer sequencing control "rebase [-i]" has, though.

damian comments and warns us:

In the "cherry-pick A..B" form, A should be older than B.
If they're the wrong order the command will silently fail.

If you want to pick the range B through D (including B) that would be B^..D (instead of B..D).
See "Git create branch from range of previous commits?" as an illustration.

As Jubobs mentions in the comments:

This assumes that B is not a root commit; you'll get an "unknown revision" error otherwise.

Note: as of Git 2.9.x/2.10 (Q3 2016), you can cherry-pick a range of commit directly on an orphan branch (empty head): see "How to make existing branch an orphan in git".

Original answer (January 2010)

A rebase --onto would be better, where you replay the given range of commit on top of your integration branch, as Charles Bailey described here.
(also, look for "Here is how you would transplant a topic branch based on one branch to another" in the git rebase man page, to see a practical example of git rebase --onto)

If your current branch is integration:

# Checkout a new temporary branch at the current location
git checkout -b tmp

# Move the integration branch to the head of the new patchset
git branch -f integration last_SHA-1_of_working_branch_range

# Rebase the patchset onto tmp, the old location of integration
git rebase --onto tmp first_SHA-1_of_working_branch_range~1 integration

That will replay everything between:

• after the parent of first_SHA-1_of_working_branch_range (hence the ~1): the first commit you want to replay
• up to "integration" (which points to the last commit you want to replay, from the working branch)

to "tmp" (which points to where integration was pointing before)

If there is any conflict when one of those commits is replayed:

• either solve it and run "git rebase --continue".
• or skip this patch, and instead run "git rebase --skip"
• or cancel the all thing with a "git rebase --abort" (and put back the integration branch on the tmp branch)

After that rebase --onto, integration will be back at the last commit of the integration branch (that is "tmp" branch + all the replayed commits)

With cherry-picking or rebase --onto, do not forget it has consequences on subsequent merges, as described here.

A pure "cherry-pick" solution is discussed here, and would involve something like:

If you want to use a patch approach then "git format-patch|git am" and "git cherry" are your options.
Currently, git cherry-pick accepts only a single commit, but if you want to pick the range B through D that would be B^..D in git lingo, so

git rev-list --reverse --topo-order B^..D | while read rev 
do 
  git cherry-pick $rev || break 
done 

But anyway, when you need to "replay" a range of commits, the word "replay" should push you to use the "rebase" feature of Git.

I learned about order with the following example which then confused me for a long time:

set.seed(1234)

ID        = 1:10
Age       = round(rnorm(10, 50, 1))
diag      = c("Depression", "Bipolar")
Diagnosis = sample(diag, 10, replace=TRUE)

data = data.frame(ID, Age, Diagnosis)

databyAge = data[order(Age),]
databyAge

The only reason this example works is because order is sorting by the vector Age, not by the column named Age in the data frame data.

To see this create an identical data frame using read.table with slightly different column names and without making use of any of the above vectors:

my.data <- read.table(text = '

  id age  diagnosis
   1  49 Depression
   2  50 Depression
   3  51 Depression
   4  48 Depression
   5  50 Depression
   6  51    Bipolar
   7  49    Bipolar
   8  49    Bipolar
   9  49    Bipolar
  10  49 Depression

', header = TRUE)

The above line structure for order no longer works because there is no vector named age:

databyage = my.data[order(age),]

The following line works because order sorts on the column age in my.data.

databyage = my.data[order(my.data$age),]

I thought this was worth posting given how confused I was by this example for so long. If this post is not deemed appropriate for the thread I can remove it.

EDIT: May 13, 2014

Below is a generalized way of sorting a data frame by every column without specifying column names. The code below shows how to sort from left to right or by right to left. This works if every column is numeric. I have not tried with a character column added.

I found the do.call code a month or two ago in an old post on a different site, but only after extensive and difficult searching. I am not sure I could relocate that post now. The present thread is the first hit for ordering a data.frame in R. So, I thought my expanded version of that original do.call code might be useful.

set.seed(1234)

v1  <- c(0,0,0,0, 0,0,0,0, 1,1,1,1, 1,1,1,1)
v2  <- c(0,0,0,0, 1,1,1,1, 0,0,0,0, 1,1,1,1)
v3  <- c(0,0,1,1, 0,0,1,1, 0,0,1,1, 0,0,1,1)
v4  <- c(0,1,0,1, 0,1,0,1, 0,1,0,1, 0,1,0,1)

df.1 <- data.frame(v1, v2, v3, v4) 
df.1

rdf.1 <- df.1[sample(nrow(df.1), nrow(df.1), replace = FALSE),]
rdf.1

order.rdf.1 <- rdf.1[do.call(order, as.list(rdf.1)),]
order.rdf.1

order.rdf.2 <- rdf.1[do.call(order, rev(as.list(rdf.1))),]
order.rdf.2

rdf.3 <- data.frame(rdf.1$v2, rdf.1$v4, rdf.1$v3, rdf.1$v1) 
rdf.3

order.rdf.3 <- rdf.1[do.call(order, as.list(rdf.3)),]
order.rdf.3

Use m.toString() or String.valueOf(m). String.valueOf uses toString() but is null safe.

This question already has a great answer, but I ran into the same error, in a different scenario: displaying a List in an EditorTemplate.

I have a model like this:

public class Foo
{
    public string FooName { get; set; }
    public List<Bar> Bars { get; set; }
}

public class Bar
{
    public string BarName { get; set; }
}

And this is my main view:

@model Foo

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })  
@Html.EditorFor(m => m.Bars)

And this is my Bar EditorTemplate (Bar.cshtml)

@model List<Bar>

<div class="some-style">
    @foreach (var item in Model)
    {
        <label>@item.BarName</label>
    }
</div>

And I got this error:

The model item passed into the dictionary is of type 'Bar', but this dictionary requires a model item of type 'System.Collections.Generic.List`1[Bar]

The reason for this error is that EditorFor already iterates the List for you, so if you pass a collection to it, it would display the editor template once for each item in the collection.

This is how I fixed this problem:

Brought the styles outside of the editor template, and into the main view:

@model Foo

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })  
<div class="some-style">
    @Html.EditorFor(m => m.Bars)
</div>

And changed the EditorTemplate (Bar.cshtml) to this:

@model Bar

<label>@Model.BarName</label>

I don't think IE supports the use of auto for setting height / width, so you could try giving this a numeric value (like Jarett suggests).

Also, it doesn't look like you are clearing your floats properly. Try adding this to your CSS for #container:

#container {
    height:100%;
    width:100%;
    overflow:hidden;
    /* for IE */
    zoom:1;
}

I guess this is what you need. Try this .

<form action="" method="get">
                <input name="search" type="text">
                <input type="button" value="Search" onclick="return updateTable();">
                </form>

and your javascript code is the same

function updateTable()
    {   
        var photoViewer = document.getElementById('photoViewer');
        var photo = document.getElementById('photo1').href;
        var numOfPics = 5;
        var columns = 3; 
        var rows = Math.ceil(numOfPics/columns);
        var content="";
        var count=0;

        content = "<table class='photoViewer' id='photoViewer'>";
            for (r = 0; r < rows; r++) {
                content +="<tr>";
                for (c = 0; c < columns; c++) {
                    count++;
                    if(count == numOfPics)break; // here is check if number of cells equal Number of Pictures to stop
                        content +="<td><a href='"+photo+"' id='photo1'><img class='photo' src='"+photo+"' alt='Photo'></a><p>City View</p></td>";
                }
                content +="</tr>";
            }
        content += "</table>";

        photoViewer.innerHTML = content; 
}

I think you may even have a separate table like a monthdetails (Monthno int, monthnames char(15)) and include values:

1 January
2 February 

.... and so on, and then join this table with your existing table in the monthnames column

SELECT t1.*,t2.Monthno from table1 
left outer join monthdetails t2
on t1.monthname=t2.monthnames
order by t2.Monthno 

When I printed response.read() I noticed that b was preprended to the string (e.g. b'{"a":1,..). The "b" stands for bytes and serves as a declaration for the type of the object you're handling. Since, I knew that a string could be converted to a dict by using json.loads('string'), I just had to convert the byte type to a string type. I did this by decoding the response to utf-8 decode('utf-8'). Once it was in a string type my problem was solved and I was easily able to iterate over the dict.

I don't know if this is the fastest or most 'pythonic' way of writing this but it works and theres always time later of optimization and improvement! Full code for my solution:

from urllib.request import urlopen
import json

# Get the dataset
url = 'http://www.quandl.com/api/v1/datasets/FRED/GDP.json'
response = urlopen(url)

# Convert bytes to string type and string type to dict
string = response.read().decode('utf-8')
json_obj = json.loads(string)

print(json_obj['source_name']) # prints the string with 'source_name' key

Selenium2Library has get_location():

import Selenium2Library
s = Selenium2Library.Selenium2Library()
url = s.get_location()

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

This will probably not make me a lot of new friends, but it should be added that the C# people have a different guideline: The enum instances are "Pascal case" (upper/lower case mixed). See stackoverflow discussion and MSDN Enumeration Type Naming Guidelines.

As we are exchanging data with a C# system, I am tempted to copy their enums exactly, ignoring Java's "constants have uppercase names" convention. Thinking about it, I don't see much value in being restricted to uppercase for enum instances. For some purposes .name() is a handy shortcut to get a readable representation of an enum constant and a mixed case name would look nicer.

So, yes, I dare question the value of the Java enum naming convention. The fact that "the other half of the programming world" does indeed use a different style makes me think it is legitimate to doubt our own religion.

You could use Directory.GetCurrentDirectory:

var path = Path.Combine(Directory.GetCurrentDirectory(), "\\fileName.txt");

Which will look for the file fileName.txt in the current directory of the application.

tf.contrib has moved out of TF starting TF 2.0 alpha.
Take a look at these tf 2.0 release notes https://github.com/tensorflow/tensorflow/releases/tag/v2.0.0-alpha0

With Jeffrey Fox's interpretation about no-cache, i've tested under chrome 52.0.2743.116 m, the result shows that no-cache has the same behavior as must-revalidate, they all will NOT use local cache when server is unreachable, and, they all will use cache while tap browser's Back/Forward button when server is unreachable. As above, i think max-age=0, must-revalidate is identical to no-cache, at least in implementation.

First try the most popular solution provided by Ravindra Bagale.

If your connection from localhost to the database still fails with error similar to the following:

Can't connect to SQL Server DB. Error: The TCP/IP connection to the host [IP address], port 1433 has failed. Error: "Connection refused: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall."

1. Open the SQL Server Configuration Manager.
2. Expand SQL Server Network Configuration for the server instance in question.
3. Double-click "TCP/IP".
4. Under the "Protocol" section, set "Enabled" to "Yes".
5. Under the "IP Addresses" section, set the TCP port under "IP All" (which is 1433 by default).

6. Under the "IP Addresses" section, find subsections with IP address 127.0.0.1 (for IPv4) and ::1 (for IPv6) and set both "Enabled" and "Active" to "Yes", and TCP port to 1433.

   

7. Go to Start > Control Panel > Administrative Tools > Services, and restart the SQL Server service (SQLEXPRESS).

This solution will work for any length

NSString *strFirst = @"Anylengthtext";
NSString *strSecond = @"Anylengthtext";
NSString *strThird = @"Anylengthtext";

NSString *strComplete = [NSString stringWithFormat:@"%@ %@ %@",strFirst,strSecond,strThird];

NSMutableAttributedString *attributedString =[[NSMutableAttributedString alloc] initWithString:strComplete];

[attributedString addAttribute:NSForegroundColorAttributeName
              value:[UIColor redColor]
              range:[strComplete rangeOfString:strFirst]];

[attributedString addAttribute:NSForegroundColorAttributeName
              value:[UIColor yellowColor]
              range:[strComplete rangeOfString:strSecond]];

[attributedString addAttribute:NSForegroundColorAttributeName
              value:[UIColor blueColor]
              range:[strComplete rangeOfString:strThird]];


self.lblName.attributedText = attributedString;

Here's a cleaner, more "plug-and-play", version of @Nagasaki45's answer. Unlike many other answers here, it works properly with strings of different lengths. It achieves this by clearing the line with just as many spaces as the length of the last line printed print. Will also work on Windows.

def print_statusline(msg: str):
    last_msg_length = len(print_statusline.last_msg) if hasattr(print_statusline, 'last_msg') else 0
    print(' ' * last_msg_length, end='\r')
    print(msg, end='\r')
    sys.stdout.flush()  # Some say they needed this, I didn't.
    print_statusline.last_msg = msg

Usage

Simply use it like this:

for msg in ["Initializing...", "Initialization successful!"]:
    print_statusline(msg)
    time.sleep(1)

This small test shows that lines get cleared properly, even for different lengths:

for i in range(9, 0, -1):
    print_statusline("{}".format(i) * i)
    time.sleep(0.5)

if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):

count before dedupe:

df.count()

do the de-dupe (convert the column you are de-duping to string type):

from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))

df.drop_duplicates(subset=['colName']).count()

can use a sorted groupby to check to see that duplicates have been removed:

df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)

Awesome, thank you!! Just had to make a few adjustments to get it working with ui-router:

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

    app.directive('head', ['$rootScope', '$compile', '$state', function ($rootScope, $compile, $state) {

    return {
        restrict: 'E',
        link: function ($scope, elem, attrs, ctrls) {

            var html = '<link rel="stylesheet" ng-repeat="(routeCtrl, cssUrl) in routeStyles" ng-href="{{cssUrl}}" />';
            var el = $compile(html)($scope)
            elem.append(el);
            $scope.routeStyles = {};

            function applyStyles(state, action) {
                var sheets = state ? state.css : null;
                if (state.parent) {
                    var parentState = $state.get(state.parent)
                    applyStyles(parentState, action);
                }
                if (sheets) {
                    if (!Array.isArray(sheets)) {
                        sheets = [sheets];
                    }
                    angular.forEach(sheets, function (sheet) {
                        action(sheet);
                    });
                }
            }

            $rootScope.$on('$stateChangeStart', function (event, toState, toParams, fromState, fromParams) {

                applyStyles(fromState, function(sheet) {
                    delete $scope.routeStyles[sheet];
                    console.log('>> remove >> ', sheet);
                });

                applyStyles(toState, function(sheet) {
                    $scope.routeStyles[sheet] = sheet;
                    console.log('>> add >> ', sheet);
                });
            });
        }
    }
}]);

I've solved this problem using JDK 7 with this code:

package FileCreationDate;

import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.attribute.BasicFileAttributes;
import java.util.Date;
import java.util.concurrent.TimeUnit;

public class Main
{
    public static void main(String[] args) {

        File file = new File("c:\\1.txt");
        Path filePath = file.toPath();

        BasicFileAttributes attributes = null;
        try
        {
            attributes =
                    Files.readAttributes(filePath, BasicFileAttributes.class);
        }
        catch (IOException exception)
        {
            System.out.println("Exception handled when trying to get file " +
                    "attributes: " + exception.getMessage());
        }
        long milliseconds = attributes.creationTime().to(TimeUnit.MILLISECONDS);
        if((milliseconds > Long.MIN_VALUE) && (milliseconds < Long.MAX_VALUE))
        {
            Date creationDate =
                    new Date(attributes.creationTime().to(TimeUnit.MILLISECONDS));

            System.out.println("File " + filePath.toString() + " created " +
                    creationDate.getDate() + "/" +
                    (creationDate.getMonth() + 1) + "/" +
                    (creationDate.getYear() + 1900));
        }
    }
}

This can be done very easily using a PostBackUrl and a regular button.

<asp:Button ID="Button1" runat="server" Text="Name of web location" PostBackUrl="web address" />

Another option when you need a simple css style of one or two properties:

View:

<tr ng-repeat="element in collection">
    [...amazing code...] 
    <td ng-style="{'background-color': getTrColor(element.myvar)}">
        {{ element.myvar }}
    </td>
    [...more amazing code...]
</tr>

Controller:

$scope.getTrColor = function (colorIndex) {
    switch(colorIndex){
        case 0: return 'red';
        case 1: return 'green';
        default: return 'yellow';
    }
};

var noHtml = Regex.Replace(inputHTML, @"<[^>]*(>|$)|&nbsp;|&zwnj;|&raquo;|&laquo;", string.Empty).Trim();

Splitting the dataset into the Training set and Test set

from sklearn.model_selection import train_test_split

How can I use the binary operator alongside the date filter?

<span class="gallery-date">{{gallery.date | date:'mediumDate' || "Date Empty"}}</span>

you also try:

<span class="gallery-date">{{ gallery.date == 'NULL' ? 'mediumDate' : "gallery.date"}}</span>

There's no need to manually set the colors. Instead, specify a grayscale colormap...

import numpy as np
import matplotlib.pyplot as plt

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()

plt.show()

Or, if you'd prefer a wider range of colormaps, you can also specify the cmap kwarg to scatter. To use the reversed version of any of these, just specify the "_r" version of any of them. E.g. gray_r instead of gray. There are several different grayscale colormaps pre-made (e.g. gray, gist_yarg, binary, etc).

import matplotlib.pyplot as plt
import numpy as np

# Generate data...
x = np.random.random(10)
y = np.random.random(10)

plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()

See here for starting the service and here for how to make it permanent. In short to test it, open a "DOS" terminal with administrator privileges and write:

shell> "C:\Program Files\MySQL\[YOUR MYSQL VERSION PATH]\bin\mysqld"

The pyplot functions you are calling, axhline() and axvline() draw lines that span a portion of the axis range, regardless of coordinates. The parameters xmin or ymin use value 0.0 as the minimum of the axis and 1.0 as the maximum of the axis.

Instead, use plt.plot((x1, x2), (y1, y2), 'k-') to draw a line from the point (x1, y1) to the point (x2, y2) in color k. See pyplot.plot.

It's the new feature in C# 6 called Interpolated Strings.

The easiest way to understand it is: an interpolated string expression creates a string by replacing the contained expressions with the ToString representations of the expressions' results.

For more details about this, please take a look at MSDN.

Now, think a little bit more about it. Why this feature is great?

For example, you have class Point:

public class Point
{
    public int X { get; set; }

    public int Y { get; set; }
}

Create 2 instances:

var p1 = new Point { X = 5, Y = 10 };
var p2 = new Point { X = 7, Y = 3 };

Now, you want to output it to the screen. The 2 ways that you usually use:

Console.WriteLine("The area of interest is bounded by (" + p1.X + "," + p1.Y + ") and (" + p2.X + "," + p2.Y + ")");

As you can see, concatenating string like this makes the code hard to read and error-prone. You may use string.Format() to make it nicer:

Console.WriteLine(string.Format("The area of interest is bounded by({0},{1}) and ({2},{3})", p1.X, p1.Y, p2.X, p2.Y));

This creates a new problem:

1. You have to maintain the number of arguments and index yourself. If the number of arguments and index are not the same, it will generate a runtime error.

For those reasons, we should use new feature:

Console.WriteLine($"The area of interest is bounded by ({p1.X},{p1.Y}) and ({p2.X},{p2.Y})");

The compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

The code below removes remove grid lines from chart area only not the ones in x&y axis labels

Chart.defaults.scale.gridLines.drawOnChartArea = false;

You can run easy_install to install python packages in your home directory even without root access. There's a standard way to do this using site.USER_BASE which defaults to something like $HOME/.local or $HOME/Library/Python/2.7/bin and is included by default on the PYTHONPATH

To do this, create a .pydistutils.cfg in your home directory:

cat > $HOME/.pydistutils.cfg <<EOF
[install]
user=1
EOF

Now you can run easy_install without root privileges:

easy_install boto

Alternatively, this also lets you run pip without root access:

pip install boto

This works for me.

When you use the IntelliJ IDE, all the project-specific settings for the project are stored under the .idea folder.

Project settings are stored with each specific project as a set of xml files under the .idea folder. If you specify the default project settings, these settings will be automatically used for each newly created project.

Check this documentation for the IDE settings and here is their recommendation on Source Control and an example .gitignore file.

Note: If you are using git or some version control system, you might want to set this folder "ignore". Example - for git, add this directory to .gitignore. This way, the application is not IDE-specific.

Do this with a file stream. When a std::ofstream is closed, the file is created. I personally like the following code, because the OP only asks to create a file, not to write in it:

#include <fstream>

int main()
{
    std::ofstream file { "Hello.txt" };
    // Hello.txt has been created here
}

The temporary variable file is destroyed right after its creation, so the stream is closed and thus the file is created.

Your last for statement is missing a body.

Python expects an indented block to follow the line with the for, or to have content after the colon.

The first style is more common, so it says it expects some indented code to follow it. You have an elif at the same indent level.

A little improvement to Matthew's answer could be a lookahead instead of the last capturing group:

.replace(/(\w+)(\d+)(?=\w+)/, "$1!NEW_ID!");

Or you could split on the decimal and join with your new id like this:

.split(/\d+/).join("!NEW_ID!");

Example/Benchmark here: https://codepen.io/jogai/full/oyNXBX

Try the following:

int[][] multi = new int[5][10];

... which is a short hand for something like this:

int[][] multi = new int[5][];
multi[0] = new int[10];
multi[1] = new int[10];
multi[2] = new int[10];
multi[3] = new int[10];
multi[4] = new int[10];

Note that every element will be initialized to the default value for int, 0, so the above are also equivalent to:

int[][] multi = new int[][]{
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },
  { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }
};

Note to anyone else:

If you have a directory like so, you can add a __main__.py file to tell the interpreter what to execute if you call the module directly.

my_module
  |
  | __init__.py
  | my_cool_file.py # print "Hello  World"
  | __main__.py # import my_cool_file

$ python my_module # Hello World

When you define an OnClickListener (or any listener) this way

btnClick.setOnClickListener(this);

you need to implement the OnClickListener in your Activity.

public class MainActivity extends ActionBarActivity implements OnClickListener{

If you want to know (or wait) until the style itself has loaded this works:

// this will work in IE 10, 11 and Safari/Chrome/Firefox/Edge
// add ES6 poly-fill for the Promise, if needed (or rewrite to use a callback)

let fetchStyle = function(url) {
  return new Promise((resolve, reject) => {
    let link = document.createElement('link');
    link.type = 'text/css';
    link.rel = 'stylesheet';
    link.onload = function() { resolve(); console.log('style has loaded'); };
    link.href = url;

    let headScript = document.querySelector('script');
    headScript.parentNode.insertBefore(link, headScript);
  });
};

jQuery has a method to check if something is a function

if ($.isFunction($.fn.dateJS)) {
    //your code using the plugin
}

You need to change the password directly in the database because at mysql the users and their profiles are saved in the database.

So there are several ways. At phpMyAdmin you simple go to user admin, choose root and change the password.

I had a similar problem where I needed to only show a value from another Excel cell if the font was black. I created this function: `Option Explicit

Function blackFont(r As Range) As Boolean If r.Font.Color = 0 Then blackFont = True Else blackFont = False End If

End Function `

In my cell I have this formula: =IF(blackFont(Y51),Y51," ")

This worked well for me to test for a black font and only show the value in the Y51 cell if it had a black font.

This could be used for OS X

let appDelegate = NSApplication.sharedApplication().delegate as AppDelegate
var managedObjectContext = appDelegate.managedObjectContext?

try this out

$("div[id^='car']:last").after($('#car2').clone());

If you want to get the list of all the functions defined in the current file, you can do it that way:

# Get this script's name.
import os
script_name = os.path.basename(__file__).rstrip(".py")

# Import it from its path so that you can use it as a Python object.
import importlib.util
spec = importlib.util.spec_from_file_location(script_name, __file__)
x = importlib.util.module_from_spec(spec)
spec.loader.exec_module(x)

# List the functions defined in it.
from inspect import getmembers, isfunction
list_of_functions = getmembers(x, isfunction)

As an application example, I use that for calling all the functions defined in my unit testing scripts.

This is a combination of codes adapted from the answers of Thomas Wouters and adrian here, and from Sebastian Rittau on a different question.

You can use apply for this, and it's a bit neater:

import numpy as np
import pandas as pd

np.random.seed(1)

df = pd.DataFrame(np.random.randn(4,4)* 4 + 3)

          0         1         2         3
0  9.497381  0.552974  0.887313 -1.291874
1  6.461631 -6.206155  9.979247 -0.044828
2  4.276156  2.002518  8.848432 -5.240563
3  1.710331  1.463783  7.535078 -1.399565

df.apply(lambda x: (x - np.mean(x)) / (np.max(x) - np.min(x)))

          0         1         2         3
0  0.515087  0.133967 -0.651699  0.135175
1  0.125241 -0.689446  0.348301  0.375188
2 -0.155414  0.310554  0.223925 -0.624812
3 -0.484913  0.244924  0.079473  0.114448

Also, it works nicely with groupby, if you select the relevant columns:

df['grp'] = ['A', 'A', 'B', 'B']

          0         1         2         3 grp
0  9.497381  0.552974  0.887313 -1.291874   A
1  6.461631 -6.206155  9.979247 -0.044828   A
2  4.276156  2.002518  8.848432 -5.240563   B
3  1.710331  1.463783  7.535078 -1.399565   B


df.groupby(['grp'])[[0,1,2,3]].apply(lambda x: (x - np.mean(x)) / (np.max(x) - np.min(x)))

     0    1    2    3
0  0.5  0.5 -0.5 -0.5
1 -0.5 -0.5  0.5  0.5
2  0.5  0.5  0.5 -0.5
3 -0.5 -0.5 -0.5  0.5

Add this function to your <script></script> and call from where ever you want in that <script></script>

<script>

function GetNow(){
    var currentdate = new Date(); 
    var datetime = currentdate.getDate() + "-"
            + (currentdate.getMonth()+1)  + "-" 
            + currentdate.getFullYear() + " "  
            + currentdate.getHours() + ":"  
            + currentdate.getMinutes() + ":" 
            + currentdate.getSeconds();
    return datetime;
}

window.alert(GetNow());

</script>

or you may simply use the Jquery which provides formatting facilities also:-

window.alert(Date.parse(new Date()).toString('yyyy-MM-dd H:i:s'));

I love the second option. It resolves all issues in one go.

By the Spring guys, used for Grails reloading but works with Java too:

Use .clf or .cla on your figure object instead of creating a new figure. From @DavidZwicker

Assuming you have imported pyplot as

import matplotlib.pyplot as plt

plt.cla() clears an axis, i.e. the currently active axis in the current figure. It leaves the other axes untouched.

plt.clf() clears the entire current figure with all its axes, but leaves the window opened, such that it may be reused for other plots.

plt.close() closes a window, which will be the current window, if not specified otherwise. plt.close('all') will close all open figures.

The reason that del fig does not work is that the pyplot state-machine keeps a reference to the figure around (as it must if it is going to know what the 'current figure' is). This means that even if you delete your ref to the figure, there is at least one live ref, hence it will never be garbage collected.

Since I'm polling on the collective wisdom here for this answer, @JoeKington mentions in the comments that plt.close(fig) will remove a specific figure instance from the pylab state machine (plt._pylab_helpers.Gcf) and allow it to be garbage collected.

To avoid exceptions killing your app you should catch those exceptions and treat them the way you wish, defining the behavior for you app on those situations where the id is not found.

begin
  current_user.comments.find(ids)
rescue
  #do something in case of exception found
end

Here's more info on exceptions in ruby.

I had a memory leak problem recently and ko.cleanNode(element); wouldn't do it for me -ko.removeNode(element); did. Javascript + Knockout.js memory leak - How to make sure object is being destroyed?

• str.toCharArray().length should work.

• Or how about:

  str.lastIndexOf("")

  Probably even runs in constant time :)

• Another one

  Matcher m = Pattern.compile("$").matcher(str);
  m.find();
  int length = m.end();
  

• One of the dumbest solutions: str.split("").length - 1

• Is this cheating: new StringBuilder(str).length()? :-)

This Worked for me. For getting the latest code from master to my branch

git rebase origin/master

This solution solve my problem: (from: https://msdn.microsoft.com/en-us/library/ms239722.aspx)

To permanently attach a database file (.mdf) from the Data Connections node

1. Open the shortcut menu for Data Connections and choose Add New Connection.

   The Add Connection dialog box appears.

2. Choose the Change button.

   The Change Data Source dialog box appears.

3. Select Microsoft SQL Server and choose the OK button.

   The Add Connection dialog box reappears, with Microsoft SQL Server (SqlClient) displayed in the Data source text box.

4. In the Server Name box, type or browse to the path to the local instance of SQL Server. You can type the following:

   • "." for the default instance on your computer.
   • "(LocalDB)\v11.0" for the default instance of SQL Server Express LocalDB.
   • ".\SQLEXPRESS" for the default instance of SQL Server Express.

   For information about SQL Server Express LocalDB and SQL Server Express, see Local Data Overview.

5. Select either Use Windows Authentication or Use SQL Server Authentication.

6. Choose Attach a database file, Browse, and open an existing .mdf file.

7. Choose the OK button.

   The new database appears in Server Explorer. It will remain connected to SQL Server until you explicitly detach it.

UPDATE: TensorFlow supports Python 3.6 on Windows since version 1.2.0 (see the release notes)

TensorFlow only supports Python 3.5 64-bit as of now. Support for Python 3.6 is a work in progress and you can track it here as well as chime in the discussion.

The only alternative to use Python 3.6 with TensorFlow on Windows currently is building TF from source.

If you don't want to uninstall your Anaconda distribution for Python 3.6 and install a previous release you can create a conda environment for Python=3.5 as in: conda create --name tensorflow python=3.5 activate tensorflow pip install tensorflow-gpu

Try using SCP on Windows to transfer files, you can download SCP from Putty's website. Then try running:

pscp.exe filename.extension [email protected]:directory/subdirectory

There is a full length guide here.

1. If you want the password prompt to go away then use key based authentication (described here).

2. To run commands remotely over ssh you have to give them as an argument to ssh, like the following:

root@host:~ # ssh root@www 'ps -ef | grep apache | grep -v grep | wc -l'

Try to install mysqli and pdo. Put it in terminal:

./configure --with-mysql=/usr/bin/mysql_config  \
--with-mysqli=mysqlnd \
--with-pdo-mysql=mysqlnd

code

var mydate = "2017-06-28T00:00:00";
var weekDayName =  moment(mydate).format('dddd');
console.log(weekDayName);

mydate is the input date. The variable weekDayName get the name of the day. Here the output is

Output

Wednesday

var mydate = "2017-08-30T00:00:00";_x000D_
console.log(moment(mydate).format('dddd'));_x000D_
console.log(moment(mydate).format('ddd'));_x000D_
console.log('Day in number[0,1,2,3,4,5,6]: '+moment(mydate).format('d'));_x000D_
console.log(moment(mydate).format('MMM'));_x000D_
console.log(moment(mydate).format('MMMM'));

Thread safe simply means that it may be used from multiple threads at the same time without causing problems. This can mean that access to any resources are synchronized, or whatever.

If you just want to print a decimal number with 2 digits after decimal point in specific format no matter of locals use something like this

dim d as double = 1.23456789
dim s as string = d.Tostring("0.##", New System.Globalization.CultureInfo("en-US"))

<input type="text" value="A new value" onfocus="javascript: if(this.value == 'A new value'){ this.value = ''; }" onblur="javascript: if(this.value==''){this.value='A new value';}" />

Use:

ini_set('display_errors','off');

It is working fine in WordPress' config.php.

sometime Activity include some Fragment when Activityneed to totally recreate Fragments content, if the sportFragmentManager.fragments without clear history fragments

    val fragments = sportFragmentManager.fragments
    val transaction = sportFragmentManager.beginTransaction()
    for (frag in fragments){
        transaction.remove(frag)
    }
    transaction.commitAllowingStateLoss()

serveral times recreate Fragments the Activity will happen (debug use tooLargeTool)

You can access the same environment variables from groovy using the same names (e.g. JOB_NAME or env.JOB_NAME).

From the documentation:

Environment variables are accessible from Groovy code as env.VARNAME or simply as VARNAME. You can write to such properties as well (only using the env. prefix):

env.MYTOOL_VERSION = '1.33'
node {
  sh '/usr/local/mytool-$MYTOOL_VERSION/bin/start'
}

These definitions will also be available via the REST API during the build or after its completion, and from upstream Pipeline builds using the build step.

For the rest of the documentation, click the "Pipeline Syntax" link from any Pipeline job

Looks like this is the best way to catch everything.

How can I properly handle 404 in ASP.NET MVC?

After wasting so much time i got to know that there was mistake in my syntax to connect with DB. I was using colon ":" instead of slash "/".

(1) if you use sid below is the syntax to get connection:

**"jdbc:oracle:thin:@{hostname}:{port}:{SID}"**

(2) if you use service name, below is the syntax to get connection:

"**jdbc:oracle:thin:@//{hostname}:{port}/{servicename}**"

Using the is or as operators is the correct way if you know the interface type at compile time and have an instance of the type you are testing. Something that no one else seems to have mentioned is Type.IsAssignableFrom:

if( typeof(IMyInterface).IsAssignableFrom(someOtherType) )
{
}

I think this is much neater than looking through the array returned by GetInterfaces and has the advantage of working for classes as well.

I can't stress this advice enough: use a reset stylesheet, then set everything explicitly. It'll cut your cross-browser CSS development time in half.

Try Eric Meyer's reset.css.

None of the other answers here worked for me, possibly from trying a combination of all of them. I was able to adapt this accepted answer to work with meld. This is now working for me with git 1.9.4, meld 3.14.0, and windows 8.1.

Edit ~/.gitconfig to look like:

[diff]
    tool = meld
    guitool = meld
[mergetool "meld"]
    path = c:/Program Files (x86)/Meld/Meld.exe
[difftool "meld"]
    path = c:/Program Files (x86)/Meld/Meld.exe

You have to close all of the streams or use try-with-resource block

static public String head(File file) throws FileNotFoundException, UnsupportedEncodingException, IOException
{
    final String readLine;
    try (FileInputStream fis = new FileInputStream(file);
            InputStreamReader isr = new InputStreamReader(fis, "UTF-8");
            LineNumberReader lnr = new LineNumberReader(isr))
    {
        readLine = lnr.readLine();
    }
    return readLine;
}

Some of your dependencies are likely signed jarfiles. When you combine them all into one big jarfile, the corresponding signature files are still present, and no longer match the "big combined" jarfile, so the runtime halts thinking the jar file has been tampered with (which it...has so to speak).

Assuming you're using ant, you can solve the problem by eliminating the signature files from your jarfile dependencies. Unfortunately, it's not possible to do this in one step in ant.

However, I was able to get this working with Ant in two steps, without specifically naming each jarfile dependency, by using:

<target name="jar" depends="compile" description="Create one big jarfile.">
    <jar jarfile="${output.dir}/deps.jar">
        <zipgroupfileset dir="jars">
            <include name="**/*.jar" />
        </zipgroupfileset>
    </jar>
    <sleep seconds="1" />
    <jar jarfile="${output.dir}/myjar.jar" basedir="${classes.dir}">
        <zipfileset src="${output.dir}/deps.jar" excludes="META-INF/*.SF" />
        <manifest>
            <attribute name="Main-Class" value="com.mycompany.MyMain" />
        </manifest>
    </jar>
</target>

The sleep element is supposed to prevent errors about files with modification dates in the future.

Other variations I found in the linked threads didn't work for me.

Use your browser's network inspector (F12) to see when the browser is requesting the bgbody.png image and what absolute path it's using and why the server is returning a 404 response.

...assuming that bgbody.png actually exists :)

Is your CSS in a stylesheet file or in a <style> block in a page? If it's in a stylesheet then the relative path must be relative to the CSS stylesheet (not the document that references it). If it's in a page then it must be relative to the current resource path. If you're using non-filesystem-based resource paths (i.e. using URL rewriting or URL routing) then this will cause problems and it's best to always use absolute paths.

Going by your relative path it looks like you store your images separately from your stylesheets. I don't think this is a good idea - I support storing images and other resources, like fonts, in the same directory as the stylesheet itself, as it simplifies paths and is also a more logical filesystem arrangement.

And if you want to vary the speed and include callbacks simply add them like this :

        jQuery.fn.extend({
            slideRightShow: function(speed,callback) {
                return this.each(function() {
                    $(this).show('slide', {direction: 'right'}, speed, callback);
                });
            },
            slideLeftHide: function(speed,callback) {
                return this.each(function() {
                    $(this).hide('slide', {direction: 'left'}, speed, callback);
                });
            },
            slideRightHide: function(speed,callback) {
                return this.each(function() {  
                    $(this).hide('slide', {direction: 'right'}, speed, callback);
                });
            },
            slideLeftShow: function(speed,callback) {
                return this.each(function() {
                    $(this).show('slide', {direction: 'left'}, speed, callback);
                });
            }
        });

If the machine is being a firewall then your solution is a very sensible one: the alternative being able to query the firewall which ends-up being very dependent on the type of firewall (if at all possible).

You've simply got it backwards. Specifying a minimum width would make the select menu always be at least that width, so it will continue expanding to 90% no matter what the window size is, also being at least the size of its longest option.

You need to use max-width instead. This way, it will let the select menu expand to its longest option, but if that expands past your set maximum of 90% width, crunch it down to that width.

For .NET Core, add System.Configuration.ConfigurationManager from NuGet manager.
And read appSetting from App.config

<appSettings>
  <add key="appSetting1" value="1000" />
</appSettings>

Add System.Configuration.ConfigurationManager from NuGet Manager

ConfigurationManager.AppSettings.Get("appSetting1")
