This would give the current date and time:

public String getCurrDate()
{
    String dt;
    Date cal = Calendar.getInstance().getTime();
    dt = cal.toLocaleString();
    return dt;
}

Keep it Simple and use Java 8:-

 Map<String, AccountGroupMappingModel> mapAccountGroup=CustomerDAO.getAccountGroupMapping();
 Map<String, AccountGroupMappingModel> mapH2ToBydAccountGroups = 
              mapAccountGroup.entrySet().stream()
                         .collect(Collectors.toMap(e->e.getValue().getH2AccountGroup(),
                                                   e ->e.getValue())
                                  );

I updated to iOS 11.0.3 then the error appeared. After restarting my iPhone and XCode, it showed "Could not launch the app", so I navigated to the phone's device management to trust, then it solved.

Renders the HTML widget of a given field. If you apply this to an entire form or collection of fields, each underlying form row will be rendered.

{# render a field row, but display a label with text "foo" #} {{ form_row(form.name, {'label': 'foo'}) }}

The second argument to form_row() is an array of variables. The templates provided in Symfony only allow to override the label as shown in the example above.

See "More about Form Variables" to learn about the variables argument.

You can use conda remove --force.

The documentation says:

--force               Forces removal of a package without removing packages
                      that depend on it. Using this option will usually
                      leave your environment in a broken and inconsistent

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.

No, that's not true. The session-timeout configures a per session timeout in case of inactivity.

Are these methods equivalent? Should I favour the web.xml config?

The setting in the web.xml is global, it applies to all sessions of a given context. Programatically, you can change this for a particular session.

That would work depending on what client.get does when passed undefined as its first parameter.

Something like this would be safer:

app.get('/:key?', function(req, res, next) {
    var key = req.params.key;
    if (!key) {
        next();
        return;
    }
    client.get(key, function(err, reply) {
        if(client.get(reply)) {
            res.redirect(reply);
        }
        else {
            res.render('index', {
                link: null
            });
        }
    });
});

There's no problem in calling next() inside the callback.

According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.

There is an implementation available at the msinttypes project page - "This project fills the absence of stdint.h and inttypes.h in Microsoft Visual Studio".

I don't have experience with this implementation, but I've seen it recommended by others on SO.

<?php
$names = array("firstname"=>"maurice",
               "lastname"=>"muteti", 
               "contact"=>"7844433339");

foreach ($names as $name => $value) {
    echo $name." ".$value."</br>";
}

print_r($names);
?>

ALTER TABLE myTable ALTER COLUMN myColumn {DataType} NULL

where {DataType} is the current data type of that column (For example int or varchar(10))

Just as Matt says, use Process.Start.

You can pass a URL, or a document. They will be started by the registered application.

Example:

Process.Start("Test.Txt");

This will start Notepad.exe with Text.Txt loaded.

You can use a TextBox and set multiline to true and canEdit to false .

Got a same error and this solved my error. Thanks! python 2 and python 3 differing in unicode handling is making pickled files quite incompatible to load. So Use python pickle's encoding argument. Link below helped me solve the similar problem when I was trying to open pickled data from my python 3.7, while my file was saved originally in python 2.x version. https://blog.modest-destiny.com/posts/python-2-and-3-compatible-pickle-save-and-load/ I copy the load_pickle function in my script and called the load_pickle(pickle_file) while loading my input_data like this:

input_data = load_pickle("my_dataset.pkl")

The load_pickle function is here:

def load_pickle(pickle_file):
    try:
        with open(pickle_file, 'rb') as f:
            pickle_data = pickle.load(f)
    except UnicodeDecodeError as e:
        with open(pickle_file, 'rb') as f:
            pickle_data = pickle.load(f, encoding='latin1')
    except Exception as e:
        print('Unable to load data ', pickle_file, ':', e)
        raise
    return pickle_data

var data = [ 
 {"Id": 10004, "PageName": "club"}, 
 {"Id": 10040, "PageName": "qaz"}, 
 {"Id": 10059, "PageName": "jjjjjjj"}
];

$.each(data, function(i, item) {
   alert(data[i].PageName);
});?

$.each(data, function(i, item) {
  alert(item.PageName);
});?

Or else You can try this method

var data = jQuery.parseJSON(response);
$.each(data, function(key,value) {
   alert(value.Id);    //It will shows the Id values
}); 

ECMAScript 6 introduced String.prototype.includes:

const string = "foo";_x000D_
const substring = "oo";_x000D_
_x000D_
console.log(string.includes(substring));

includes doesn’t have Internet Explorer support, though. In ECMAScript 5 or older environments, use String.prototype.indexOf, which returns -1 when a substring cannot be found:

var string = "foo";_x000D_
var substring = "oo";_x000D_
_x000D_
console.log(string.indexOf(substring) !== -1);

'\r' is the carriage return character. The main times it would be useful are:

1. When reading text in binary mode, or which may come from a foreign OS, you'll find (and probably want to discard) it due to CR/LF line-endings from Windows-format text files.

2. When writing to an interactive terminal on stdout or stderr, '\r' can be used to move the cursor back to the beginning of the line, to overwrite it with new contents. This makes a nice primitive progress indicator.

The example code in your post is definitely a wrong way to use '\r'. It assumes a carriage return will precede the newline character at the end of a line entered, which is non-portable and only true on Windows. Instead the code should look for '\n' (newline), and discard any carriage return it finds before the newline. Or, it could use text mode and have the C library handle the translation (but text mode is ugly and probably should not be used).

I traced the Apache code through DigestUtils and sha256 seems to default back to java.security.MessageDigest for calculation. Apache does not implement an independent sha256 solution. I was looking for an independent implementation to compare against the java.security library. FYI only.

This ORA error is occurred because of violation of unique constraint.

ORA-00001: unique constraint (constraint_name) violated

This is caused because of trying to execute an INSERT or UPDATE statement that has created a duplicate value in a field restricted by a unique index.

You can resolve this either by

• changing the constraint to allow duplicates, or
• drop the unique constraint or you can change your SQL to avoid duplicate inserts

To get the id of the parent div:

$(buttonSelector).parents('div:eq(0)').attr('id');

Also, you can refactor your code quite a bit:

$('button').click( function() {
 var correct = Number($(this).attr('rel'));
 validate(Number($(this).siblings('input').val()), correct);
 $(this).parents('div:eq(0)').html(feedback);
});

Now there is no need for a button-class

explanation
eq(0), means that you will select one element from the jQuery object, in this case element 0, thus the first element. http://docs.jquery.com/Selectors/eq#index
$(selector).siblings(siblingsSelector) will select all siblings (elements with the same parent) that match the siblingsSelector http://docs.jquery.com/Traversing/siblings#expr
$(selector).parents(parentsSelector) will select all parents of the elements matched by selector that match the parent selector. http://docs.jquery.com/Traversing/parents#expr
Thus: $(selector).parents('div:eq(0)'); will match the first parent div of the elements matched by selector.

You should have a look at the jQuery docs, particularly selectors and traversing:

• http://docs.jquery.com/
• http://docs.jquery.com/Selectors
• http://docs.jquery.com/Traversing

The command prompt wouldn't use JAVA_HOME to find javac.exe, it would use PATH.

Just delete the table and create a new table with a different name. Also Don't delete entire row for that table. It seems when entire row containing table row is delete it damages the DataBodyRange is damaged

You're doing things in the wrong order.

You need to first add all JComponents to the JFrame, and only then call pack() and then setVisible(true) on the JFrame

If you later added JComponents that could change the GUI's size you will need to call pack() again, and then repaint() on the JFrame after doing so.

fnCalledFunction(Param1,Param2, window.YourOptionalParameter)

If above function is called from many places and you are sure first 2 parameters are passed from every where but not sure about 3rd parameter then you can use window.

window.param3 will handle if it is not defined from the caller method.

this would be perfect cause we are doing operation on matrix, and the answer should be a single number

sum(sum(matrix==value))

I think you should add further control to this:

    var disableRes = false;
    var refreshWindow = function() {
        disableRes = false;
        location.reload();
    }
    var resizeTimer;
    if (disableRes == false) {
        jQuery(window).resize(function() {
            disableRes = true;
            clearTimeout(resizeTimer);
            resizeTimer = setTimeout(refreshWindow, 1000);
        });
    }

You need to update the output of json.load with a_dict and then dump the result. And you cannot append to the file but you need to overwrite it.

Abstraction: Hiding the data. Encapsulation: Binding the data.

I'm rusty with structs, so I'm probably missing a few keywords here. But why not start with a global structure with the defaults initialized, copy it to your local variable, then modify it?

An initializer like:

void init_struct( structType * s )
{
   memcopy(s,&defaultValues,sizeof(structType));
}

Then when you want to use it:

structType foo;
init_struct( &foo ); // get defaults
foo.fieldICareAbout = 1; // modify fields
update( &foo ); // pass to function

Because a reference is 'managed', but not hydrated, it can also allow you to remove an entity by ID, without needing to load it into memory first.

As you can't remove an unmanaged entity, it's just plain silly to load all fields using find(...) or createQuery(...), only to immediately delete it.

MyLargeObject myObject = em.getReference(MyLargeObject.class, objectId);
em.remove(myObject);

Nope, it is more complicated than just calling a method, if you want to transparently add it into the user's calendar.

You've got a couple of choices;

1. Calling the intent to add an event on the calendar
   This will pop up the Calendar application and let the user add the event. You can pass some parameters to prepopulate fields:

   Calendar cal = Calendar.getInstance();              
   Intent intent = new Intent(Intent.ACTION_EDIT);
   intent.setType("vnd.android.cursor.item/event");
   intent.putExtra("beginTime", cal.getTimeInMillis());
   intent.putExtra("allDay", false);
   intent.putExtra("rrule", "FREQ=DAILY");
   intent.putExtra("endTime", cal.getTimeInMillis()+60*60*1000);
   intent.putExtra("title", "A Test Event from android app");
   startActivity(intent);
   

   Or the more complicated one:

2. Get a reference to the calendar with this method
   (It is highly recommended not to use this method, because it could break on newer Android versions):

   private String getCalendarUriBase(Activity act) {
   
       String calendarUriBase = null;
       Uri calendars = Uri.parse("content://calendar/calendars");
       Cursor managedCursor = null;
       try {
           managedCursor = act.managedQuery(calendars, null, null, null, null);
       } catch (Exception e) {
       }
       if (managedCursor != null) {
           calendarUriBase = "content://calendar/";
       } else {
           calendars = Uri.parse("content://com.android.calendar/calendars");
           try {
               managedCursor = act.managedQuery(calendars, null, null, null, null);
           } catch (Exception e) {
           }
           if (managedCursor != null) {
               calendarUriBase = "content://com.android.calendar/";
           }
       }
       return calendarUriBase;
   }
   

   and add an event and a reminder this way:

   // get calendar
   Calendar cal = Calendar.getInstance();     
   Uri EVENTS_URI = Uri.parse(getCalendarUriBase(this) + "events");
   ContentResolver cr = getContentResolver();
   
   // event insert
   ContentValues values = new ContentValues();
   values.put("calendar_id", 1);
   values.put("title", "Reminder Title");
   values.put("allDay", 0);
   values.put("dtstart", cal.getTimeInMillis() + 11*60*1000); // event starts at 11 minutes from now
   values.put("dtend", cal.getTimeInMillis()+60*60*1000); // ends 60 minutes from now
   values.put("description", "Reminder description");
   values.put("visibility", 0);
   values.put("hasAlarm", 1);
   Uri event = cr.insert(EVENTS_URI, values);
   
   // reminder insert
   Uri REMINDERS_URI = Uri.parse(getCalendarUriBase(this) + "reminders");
   values = new ContentValues();
   values.put( "event_id", Long.parseLong(event.getLastPathSegment()));
   values.put( "method", 1 );
   values.put( "minutes", 10 );
   cr.insert( REMINDERS_URI, values );
   

   You'll also need to add these permissions to your manifest for this method:

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

Update: ICS Issues

The above examples use the undocumented Calendar APIs, new public Calendar APIs have been released for ICS, so for this reason, to target new android versions you should use CalendarContract.

More infos about this can be found at this blog post.

I was able to slightly improve Jai's answer to work in the case of you having more than one button dropdown with a pretty good presentation that works with bootstrap 3:

Code for The Button

<div class="btn-group">
  <button type="button" class="btn btn-default dropdown-toggle" data-toggle="dropdown">
    Option: <span class="selection">Option 1</span><span class="caret"></span>
  </button>
  <ul class="dropdown-menu" role="menu">
    <li><a href="#">Option 1</a></li>
    <li><a href="#">Option 2</a></li>
    <li><a href="#">Option 3</a></li>
  </ul>
</div>

JQuery Snippet

$(".dropdown-menu li a").click(function(){

  $(this).parents(".btn-group").find('.selection').text($(this).text());
  $(this).parents(".btn-group").find('.selection').val($(this).text());

});

I also added a 5px margin-right to the "selection" class.

After data-binding, do this:

ddlColor.Items.Insert(0, new ListItem("Select","NA")); //updated code

Or follow Brian's second suggestion if you want to do it in markup.

You should probably add a RequiredFieldValidator control and set its InitialValue to "NA".

<asp:RequiredFieldValidator .. ControlToValidate="ddlColor" InitialValue="NA" />

If the deletion has not been committed, the command below will restore the deleted file in the working tree.

$ git checkout -- <file>

You can get a list of all the deleted files in the working tree using the command below.

$ git ls-files --deleted

If the deletion has been committed, find the commit where it happened, then recover the file from this commit.

$ git rev-list -n 1 HEAD -- <file>
$ git checkout <commit>^ -- <file>

In case you are looking for the path of the file to recover, the following command will display a summary of all deleted files.

$ git log --diff-filter=D --summary

Update:

Since git rm . deletes all files in this and child directories in the working checkout as well as in the index, you need to undo each of these changes:

git reset HEAD . # This undoes the index changes
git checkout .   # This checks out files in this and child directories from the HEAD

This should do what you want. It does not affect parent folders of your checked-out code or index.

Old answer that wasn't:

reset HEAD

will do the trick, and will not erase any uncommitted changes you have made to your files.

after that you need to repeat any git add commands you had queued up.

The <h:outputLink> renders a fullworthy HTML <a> element with the proper URL in the href attribute which fires a bookmarkable GET request. It cannot directly invoke a managed bean action method.

<h:outputLink value="destination.xhtml">link text</h:outputLink>

The <h:commandLink> renders a HTML <a> element with an onclick script which submits a (hidden) POST form and can invoke a managed bean action method. It's also required to be placed inside a <h:form>.

<h:form>
    <h:commandLink value="link text" action="destination" />
</h:form>

The ?faces-redirect=true parameter on the <h:commandLink>, which triggers a redirect after the POST (as per the Post-Redirect-Get pattern), only improves bookmarkability of the target page when the link is actually clicked (the URL won't be "one behind" anymore), but it doesn't change the href of the <a> element to be a fullworthy URL. It still remains #.

<h:form>
    <h:commandLink value="link text" action="destination?faces-redirect=true" />
</h:form>

Since JSF 2.0, there's also the <h:link> which can take a view ID (a navigation case outcome) instead of an URL. It will generate a HTML <a> element as well with the proper URL in href.

<h:link value="link text" outcome="destination" />

So, if it's for pure and bookmarkable page-to-page navigation like the SO username link, then use <h:outputLink> or <h:link>. That's also better for SEO since bots usually doesn't cipher POST forms nor JS code. Also, UX will be improved as the pages are now bookmarkable and the URL is not "one behind" anymore.

When necessary, you can do the preprocessing job in the constructor or @PostConstruct of a @RequestScoped or @ViewScoped @ManagedBean which is attached to the destination page in question. You can make use of @ManagedProperty or <f:viewParam> to set GET parameters as bean properties.

** Update ** A scalars converter has been added to retrofit that allows for a String response with less ceremony than my original answer below.

Example interface --

public interface GitHubService {
    @GET("/users/{user}")
    Call<String> listRepos(@Path("user") String user);
}

Add the ScalarsConverterFactory to your retrofit builder. Note: If using ScalarsConverterFactory and another factory, add the scalars factory first.

Retrofit retrofit = new Retrofit.Builder()
    .baseUrl(BASE_URL)
    .addConverterFactory(ScalarsConverterFactory.create())
    // add other factories here, if needed.
    .build();

You will also need to include the scalars converter in your gradle file --

implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'

--- Original Answer (still works, just more code) ---

I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject land. I suspect your specific problem might be better solved using a custom gson TypeAdapter or a retrofit Converter if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -

First, if you are using Retrofit 2, you should start using the Call API. Instead of sending an object to convert as the type parameter, use ResponseBody from okhttp --

public interface GitHubService {
    @GET("/users/{user}")
    Call<ResponseBody> listRepos(@Path("user") String user);
}

then you can create and execute your call --

GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
    @Override
    public void onResponse(Response<ResponseBody> response) {
        try {
            System.out.println(response.body().string());
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    @Override
    public void onFailure(Throwable t) {
        e.printStackTrace();
    }
});

Note The code above calls string() on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream() instead. See the ResponseBody docs.

As already said, the easiest way is to use querystring.

But if you cannot, because of security reason, you should consider using cookies.

Add:

build.gradle 

in your root project folder, and use plugin for example:

apply plugin: 'idea'
//and standard one
apply plugin: 'java'

and with this fire from command line:

gradle cleanIdea 

and after that:

gradle idea

After that everything should work

This is a good summary I found:

The Carriage Return (CR) character (0x0D, \r) moves the cursor to the beginning of the line without advancing to the next line. This character is used as a new line character in Commodore and Early Macintosh operating systems (OS-9 and earlier).

The Line Feed (LF) character (0x0A, \n) moves the cursor down to the next line without returning to the beginning of the line. This character is used as a new line character in UNIX based systems (Linux, Mac OSX, etc)

The End of Line (EOL) sequence (0x0D 0x0A, \r\n) is actually two ASCII characters, a combination of the CR and LF characters. It moves the cursor both down to the next line and to the beginning of that line. This character is used as a new line character in most other non-Unix operating systems including Microsoft Windows, Symbian OS and others.

I was already using jquery. But I think its intuitive enough to just have:

var total_amount = 0; 
$.each(traveler, function( i, v ) { total_amount += v.Amount ; });

This is basically just a short-hand version of @akhouri's answer.

Since everyone answering this question has problems due to the 500 video limit here's an alternate solution using youtube_dl in Python 3. Also, no API key is needed.

1. Install youtube_dl: sudo pip3 install youtube-dl
2. Find out your target channel's channel id. The ID is going to start with UC. Replace the C for Channel with U for Upload (i.e. UU...), this is the upload playlist.
3. Use the playlist downloader feature from youtube-dl. Ideally you do NOT want to download every video in the playlist which is the default, but only the metadata.

Example (warning -- takes tens of minutes):

import youtube_dl, pickle

             # UCVTyTA7-g9nopHeHbeuvpRA is the channel id (1517+ videos)
PLAYLIST_ID = 'UUVTyTA7-g9nopHeHbeuvpRA'  # Late Night with Seth Meyers

with youtube_dl.YoutubeDL({'ignoreerrors': True}) as ydl:

    playd = ydl.extract_info(PLAYLIST_ID, download=False)

    with open('playlist.pickle', 'wb') as f:
        pickle.dump(playd, f, pickle.HIGHEST_PROTOCOL)

    vids = [vid for vid in playd['entries'] if 'A Closer Look' in vid['title']]
    print(sum('Trump' in vid['title'] for vid in vids), '/', len(vids))

C and C++ take a very abstract view of I/O, and there is no standard way of doing what you want. There are standard ways to get characters from the standard input stream, if there are any to get, and nothing else is defined by either language. Any answer will therefore have to be platform-specific, perhaps depending not only on the operating system but also the software framework.

There's some reasonable guesses here, but there's no way to answer your question without knowing what your target environment is.

I realize this is pretty late, but I had a similar problem and I figured I'd post what worked for me. I used the iconv utility (e.g., "iconv file.pcl -f UTF-8 -t ISO-8859-1 -c"). The "-c" option skips characters that can't be translated.

In a response, this is where the requested resource is returned to the client (the most common use of the message body), or perhaps explanatory text if there's an error. In a request, this is where user-entered data or uploaded files are sent to the server.

git remote update && git status 

Found this on the answer to Check if pull needed in Git

git remote update to bring your remote refs up to date. Then you can do one of several things, such as:

1. git status -uno will tell you whether the branch you are tracking is ahead, behind or has diverged. If it says nothing, the local and remote are the same.

2. git show-branch *master will show you the commits in all of the branches whose names end in master (eg master and origin/master).

If you use -v with git remote update you can see which branches got updated, so you don't really need any further commands.

The following are possible issues:

• The most likely one is that the Security Group is not configured properly to provide SSH access on port 22 to your i.p. Change in security setting does not require a restart of server for it to be effective but need to wait a few minutes for it to be applicable.

• The local firewall configuration does not allow SSH access to the server. ( you can try a different internet connection, your phone/dongle to try it)

• The server is not started properly ( then the access checks will fail even on the amazon console), in which case you would need to stop and start the server.

• The most readable: val === false || val === true.
• Also readable: typeof variable == typeof true.

• The shortest, but not readable at all: !!val === val.

  Explanation:

  • [!!] The double exclamation mark converts the value into a Boolean.
  • [===] The triple equals test for strict equality: both the type (Boolean) and the value have to be the same.
  • If the original value is not a Boolean one, it won't pass the triple equals test. If it is a Boolean variable, it will pass the triple equals test (with both type & value).

  Tests:

  • !!5 === 5 // false
  • !!'test' === 'test' // false
  • let val = new Date(); !!val === val // false
  • !!true === true // true
  • !!false === false // true

Here is example for list of Objects

Map<String, Long> requirementCountMap = requirements.stream().collect(Collectors.groupingBy(Requirement::getRequirementType, Collectors.counting()));

To create an empty vector use:

vec <- c();

Please note, I am not making any assumptions about the type of vector you require, e.g. numeric.

Once the vector has been created you can add elements to it as follows:

For example, to add the numeric value 1:

vec <- c(vec, 1);

or, to add a string value "a"

vec <- c(vec, "a");

I think that the URI class is the one that you are looking for.

I had the same problem, but I noticed that my datagrid lost the rows's header after the datagrid.visible property changed.

Try to update the rows's headers with the Datagrid.visiblechanged event.

Reference - Turning off this option can help you avoid re-creating a table, it can also lead to changes being lost. For example, suppose that you enable the Change Tracking feature in SQL Server 2008 to track changes to the table. When you perform an operation that causes the table to be re-created, you receive the error message that is mentioned in the "Symptoms" section. However, if you turn off this option, the existing change tracking information is deleted when the table is re-created. Therefore,Microsoft recommend that you do not work around this problem by turning off the option.

You don't really need the MockitoAnnotations.initMocks(this); if you're using mockito 1.9 ( or newer ) - all you need is this:

@InjectMocks
private MyTestObject testObject;

@Mock
private MyDependentObject mockedObject;

The @InjectMocks annotation will inject all your mocks to the MyTestObject object.

for just background color

Tabbarcontroller.tabBar.barTintColor=[UIColor redcolour];

or this in App Delegate

[[UITabBar appearance] setBackgroundColor:[UIColor blackColor]];

for changing color of unselect icons of tabbar

For iOS 10:

// this code need to be placed on home page of tabbar    
for(UITabBarItem *item in self.tabBarController.tabBar.items) {
    item.image = [item.image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
}

Above iOS 10:

// this need to be in appdelegate didFinishLaunchingWithOptions
[[UITabBar appearance] setUnselectedItemTintColor:[UIColor blackColor]];

There's another reason that this can be thrown, even if you're not using dynamic/ExpandoObject. If you are doing a loop, like this:

@foreach (var folder in ViewBag.RootFolder.ChildFolders.ToList())
{
    @Html.Partial("ContentFolderTreeViewItems", folder)
}

In that case, the "var" instead of the type declaration will throw the same error, despite the fact that RootFolder is of type "Folder. By changing the var to the actual type, the problem goes away.

@foreach (ContentFolder folder in ViewBag.RootFolder.ChildFolders.ToList())
{
    @Html.Partial("ContentFolderTreeViewItems", folder)
}

The problem with creating dynamic SQL using string expression is that SQL does limit the evaluation of string expressions to 4,000 chars. You can assign a longer string to an nvarchar(max) variable, but as soon as you include + in the expression (such as + CASE ... END + ), then the expression result is limited to 4,000 chars.

One way to fix this is to use CONCAT instead of +. For example:

SET @sql = CONCAT(@sql, N'
     ... dynamic SQL statements ...
    ', CASE ... END, N'
     ... dynamic SQL statements ...
    ')

Where @sql is declared as nvarchar(max).

Bootstrap modal exposes events. Listen for the the shown event like this

$('#my-modal').on('shown', function(){
  // code here
});

You need to send HTML emails. With <br />s in the email, you will always have your line breaks.

This is working code

protected void Page_Load(object sender, EventArgs e)
        {
            if (!Page.IsPostBack)
            { 
                    DropDownList1.DataTextField = "user_name";
                    DropDownList1.DataValueField = "user_id";
                    DropDownList1.DataSource = getData();// get the data into the list you can set it
                    DropDownList1.DataBind();

    DropDownList1.SelectedIndex = DropDownList1.Items.IndexOf(DropDownList1.Items.FindByText("your default selected text"));
            }
        }

The regular expressions posted in this thread are out of date now because of the new generic top level domains (gTLDs) coming in (e.g. .london, .basketball, .??). To validate an email address there are two answers (That would be relevant to the vast majority).

1. As the main answer says - don't use a regular expression, just validate it by sending an email to the address (Catch exceptions for invalid addresses)
2. Use a very generic regex to at least make sure that they are using an email structure {something}@{something}.{something}. There's no point in going for a detailed regex because you won't catch them all and there'll be a new batch in a few years and you'll have to update your regular expression again.

I have decided to use the regular expression because, unfortunately, some users don't read forms and put the wrong data in the wrong fields. This will at least alert them when they try to put something which isn't an email into the email input field and should save you some time supporting users on email issues.

Just wanted to share another way of accessing 'App_Data' folder in my mvc application in case that someone needs this.

 Path.Combine(HttpRuntime.AppDomainAppPath,"App_Data")

this prototype:

  int execlp(const char *file, const char *arg, ...);

Says that execlp ìs a variable argument function. It takes 2 const char *. The rest of the arguments, if any, are the additional arguments to hand over to program we want to run - also char * - all these are C strings (and the last argument must be a NULL pointer)

So, the file argument is the path name of an executable file to be executed. arg is the string we want to appear as argv[0] in the executable. By convention, argv[0] is just the file name of the executable, normally it's set to the same as file.

The ... are now the additional arguments to give to the executable.

Say you run this from a commandline/shell:

$ ls

That'd be execlp("ls", "ls", (char *)NULL); Or if you run

$ ls -l /

That'd be execlp("ls", "ls", "-l", "/", (char *)NULL);

So on to execlp("/bin/sh", ..., "ls -l /bin/??", ...);

Here you are going to the shell, /bin/sh , and you're giving the shell a command to execute. That command is "ls -l /bin/??". You can run that manually from a commandline/shell:

 $ ls -l /bin/??

Now, how do you run a shell and tell it to execute a command ? You open up the documentation/man page for your shell and read it.

What you want to run is:

$ /bin/sh -c "ls -l /bin/??"

This becomes

  execlp("/bin/sh","/bin/sh", "-c", "ls -l /bin/??", (char *)NULL);

Side note: The /bin/?? is doing pattern matching, this pattern matching is done by the shell, and it expands to all files under /bin/ with 2 characters. If you simply did

  execlp("ls","ls", "-l", "/bin/??", (char *)NULL);

Probably nothing would happen (unless there's a file actually named /bin/??) as there's no shell that interprets and expands /bin/??

Try this solution:

for m in ["a", "á", "à", "ã", "â"]:
    try:
        somelist.remove(m)
    except:
        pass

Just for your information. and and or operators are also using to return values. It is useful when you need to assign value to variable but you have some pre-requirements

operator or returns first not null value

#init values
a,b,c,d = (1,2,3,None)

print(d or a or b or c)
#output value of a - 1

print(b or a or c or d)
#output value of b - 2

Operator and returns last value in the sequence if any of the members don't have None value or if they have at least one None value we get None

print(a and d and b and c)
#output: None

print(a or b or c)
#output value of c - 3

The toString() method of Selenium's By-Class produces something like "By.xpath: //XpathFoo"

So you could take a substring starting at the colon with something like this:

String selector = divA.toString().substring(s.indexOf(":") + 2);

With this, you could find your element inside your other element with this:

WebElement input = driver.findElement( By.xpath( selector + "//input" ) );

Advantage: You have to search only once on the actual SUT, so it could give you a bonus in performance.

Disadvantage: Ugly... if you want to search for the parent element with css selectory and use xpath for it's childs, you have to check for types before you concatenate... In this case, Slanec's solution (using findElement on a WebElement) is much better.

If you're on windows and using apache, maybe via WAMP or the Drupal stack installer, you can additionally download the git for windows package, which includes many useful linux command line tools, one of which is openssl.

The following command creates the self signed certificate and key needed for apache and works fine in windows:

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout privatekey.key -out certificate.crt

Well there are a bunch of different utilities for this, e.g. Apache Commons Lang String Utils

but in the end, it has to loop over the string to count the occurrences one way or another.

Note also that the countMatches method above has the following signature so will work for substrings as well.

public static int countMatches(String str, String sub)

The source for this is (from here):

public static int countMatches(String str, String sub) {
    if (isEmpty(str) || isEmpty(sub)) {
        return 0;
    }
    int count = 0;
    int idx = 0;
    while ((idx = str.indexOf(sub, idx)) != -1) {
        count++;
        idx += sub.length();
    }
    return count;
}

I was curious if they were iterating over the string or using Regex.

If you have User scoped settings you may also have a user.config file somewhere in the [Userfolder]\AppData\Local\[ProjectName] folder.

If you later remove the User scoped settings the user.config will not automatically be removed, and it's presence may cause the same error message. Deleting the folder did the trick for me.

Use String.Format() with multiple parameters.

using System;

namespace TimeSpanFormat
{
    class Program
    {
        static void Main(string[] args)
        {
            TimeSpan dateDifference = new TimeSpan(0, 0, 6, 32, 445);
            string formattedTimeSpan = string.Format("{0:D2} hrs, {1:D2} mins, {2:D2} secs", dateDifference.Hours, dateDifference.Minutes, dateDifference.Seconds);
            Console.WriteLine(formattedTimeSpan);
        }
    }
}

try this...

public class Student 
    {
        public int Grade { get; set; }
        public string Name { get; set; }
        public override string ToString()
        {
            return string.Format("Name{0} : Grade{1}", Name, Grade);
        }
    }

class Program
{
    static void Main(string[] args)
    {

      List<Student> listStudents = new List<Student>();
      listStudents.Add(new Student() { Grade = 10, Name = "Pedro" });
      listStudents.Add(new Student() { Grade = 10, Name = "Luana" });
      listStudents.Add(new Student() { Grade = 10, Name = "Maria" });
      listStudents.Add(new Student() { Grade = 11, Name = "Mario" });
      listStudents.Add(new Student() { Grade = 15, Name = "Mario" });
      listStudents.Add(new Student() { Grade = 10, Name = "Bruno" });
      listStudents.Add(new Student() { Grade = 10, Name = "Luana" });
      listStudents.Add(new Student() { Grade = 11, Name = "Luana" });
      listStudents.Add(new Student() { Grade = 22, Name = "Maria" });
      listStudents.Add(new Student() { Grade = 55, Name = "Bruno" });
      listStudents.Add(new Student() { Grade = 77, Name = "Maria" });
      listStudents.Add(new Student() { Grade = 66, Name = "Maria" });
      listStudents.Add(new Student() { Grade = 88, Name = "Bruno" });
      listStudents.Add(new Student() { Grade = 42, Name = "Pedro" });
      listStudents.Add(new Student() { Grade = 33, Name = "Bruno" });
      listStudents.Add(new Student() { Grade = 33, Name = "Luciana" });
      listStudents.Add(new Student() { Grade = 17, Name = "Maria" });
      listStudents.Add(new Student() { Grade = 25, Name = "Luana" });
      listStudents.Add(new Student() { Grade = 25, Name = "Pedro" });

      listStudents.GroupBy(g => g.Name).OrderBy(g => g.Key).SelectMany(g => g.OrderByDescending(x => x.Grade)).ToList().ForEach(x => Console.WriteLine(x.ToString()));
    }
}

I have had same problem. I found the thread when I search solution on google, still I don't find any clue. But I think I found the reason after studying, the below example will explain clearly my clue.

    echo "new text" > new.txt
    git add new.txt
    git commit -m "dummy"

for now, the file new.txt is considered as a text file.

    echo -e "newer text\000" > new.txt
    git diff

you will get this result

diff --git a/new.txt b/new.txt
index fa49b07..410428c 100644
Binary files a/new.txt and b/new.txt differ

and try this

git diff -a

you will get below

    diff --git a/new.txt b/new.txt
    index fa49b07..9664e3f 100644
    --- a/new.txt
    +++ b/new.txt
    @@ -1 +1 @@
    -new file
    +newer text^@

The answer depends on what is in your hash. If you have a simple hash a simple

print map { "$_ $h{$_}\n" } keys %h;

or

print "$_ $h{$_}\n" for keys %h;

will do, but if you have a hash that is populated with references you will something that can walk those references and produce a sensible output. This walking of the references is normally called serialization. There are many modules that implement different styles, some of the more popular ones are:

• Data::Dumper
• Data::Dump::Streamer
• YAML::XS
• JSON::XS
• XML::Dumper

Due to the fact that Data::Dumper is part of the core Perl library, it is probably the most popular; however, some of the other modules have very good things to offer.

You could also use a StringVar variable, even if it's not strictly necessary:

v = StringVar()

e = Entry(master, textvariable=v)
e.pack()

v.set("a default value")
s = v.get()

For more information, see this page on effbot.org.

In the error message, instead of telling you that you can't concatenate two objects by showing their values (a string and None in this example), the Python interpreter tells you this by showing the types of the objects that you tried to concatenate. The type of every string is str while the type of the single None instance is called NoneType.

You normally do not need to concern yourself with NoneType, but in this example it is necessary to know that type(None) == NoneType.

The following query should give the exact stuff you are looking out for.

select datediff(second, '2010-01-22 15:29:55.090' , '2010-01-22 15:30:09.153')

Here is the link from MSDN for what all you can do with datediff function . https://msdn.microsoft.com/en-us/library/ms189794.aspx

I believe that the assumption that the graph is connected can be handful. thus, you can use the proof shown above, that the running time is O(|V|). if not, then |E|>|V|. reminder: the running time of DFS is O(|V|+|E|).

Because a null collection is not the same thing as an empty collection. An empty collection is a collection object with no elements; a null collection is a nonexistent object.

Here's something to try: Declare two collections of any sort. Initialize one normally so that it's empty, and assign the other the value null. Then try adding an object to both collections and see what happens.

In my case, the folder which served the files was a symbolic link to another folder, made with

ln -sf /origin /var/www/destination

Even though the permissions (user and group) where correct on the destination folder (the symbolic link), I still had the error because Nginx needed to have permissions to the origin folder whole's hierarchy as well.

There's no pretty way. You might be able to use a proxy with the handler having the target methods and delegating everything else to them. Of course you'll have to use a factory because there'll be no constructor.

In my case there were no unified authentication (e. g. within the domain + AD-like service) between my machine and git virtual server. Therefore git users and group are local for the virtual server. In my case my remote user (which I use to login into remote server) was just not added into remote git group.

ssh root@<remote_git_server>
usermod -G <remote_git_group> <your_remote_user>

After that check the permissions like it's described in the posts above...

Another editor-based solution: text "rectangles" in Emacs.

Highlight the code you want to comment out, then C-x-r-t #

To un-comment the code: highlight, then C-x-r-k

I use this all-day, every day. (Assigned to hot-keys, of course.)

This and powerful regex search/replace is the reason I tolerate Emacs's other "eccentricities".

If anyone comes here after me, this is the answer that worked for me.

NOTE: please make to read the comments before using this, this not complete. The best advice for update queries I can give is to switch to SqlServer ;)

update mytable t
set z = (
  with comp as (
    select b.*, 42 as computed 
    from mytable t 
    where bs_id = 1
  )
  select c.computed
  from  comp c
  where c.id = t.id
)

Good luck,

Use the ViewContext and look at the RouteData collection to extract both the controller and action elements. But I think setting some data variable that indicates the application context (e.g., "editmode" or "error") rather than controller/action reduces the coupling between your views and controllers.

If you're willing to include the jQuery UI library, in addition to jQuery itself, then you can simply use hide(), with additional arguments, as follows:

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this).hide('slide',{direction:'right'},1000);

            });
    });

JS Fiddle demo.

Without using jQuery UI, you could achieve your aim just using animate():

$(document).ready(
    function(){
        $('#slider').click(
            function(){
                $(this)
                    .animate(
                        {
                            'margin-left':'1000px'
                            // to move it towards the right and, probably, off-screen.
                        },1000,
                        function(){
                            $(this).slideUp('fast');
                            // once it's finished moving to the right, just 
                            // removes the the element from the display, you could use
                            // `remove()` instead, or whatever.
                        }
                        );

            });
    });

If you do choose to use jQuery UI, then I'd recommend linking to the Google-hosted code, at: https://ajax.googleapis.com/ajax/libs/jqueryui/1.8.6/jquery-ui.min.js

Seems like you use Angular 4.3 version, I also faced with same problem. Use Angular 4.0.1 and post with code by @trichetricheand and it will work. I am also not sure how to solve it on Angular 4.3 :S

Despite following most of the advice on this page, I was still getting problems on Windows Server 2012. Installing .NET Extensibility 4.5 solved it for me:

Add Roles and Features > Server Roles > Web Server (IIS) > Web Server > Application Development > .NET Extensibility 4.5

You can just add the padding to tour block element and add background-origin style like so:

.block {
  position: relative;
  display: inline-block;
  padding: 10px 12px;
  border:1px solid #e5e5e5;
  background-size: contain;
  background-position: center;
  background-repeat: no-repeat;
  background-origin: content-box;
  background-image: url(_your_image_);
  height: 14rem;
  width: 10rem;
}

You can check several https://www.w3schools.com/cssref/css3_pr_background-origin.asp

I just had the same problem .I solve it by adding this line:

@GeneratedValue(strategy=GenerationType.IDENTITY)

The Android API already provides a method to achieve that. Try this:

Rect offsetViewBounds = new Rect();
//returns the visible bounds
childView.getDrawingRect(offsetViewBounds);
// calculates the relative coordinates to the parent
parentViewGroup.offsetDescendantRectToMyCoords(childView, offsetViewBounds); 

int relativeTop = offsetViewBounds.top;
int relativeLeft = offsetViewBounds.left;

Here is the doc

Addition for accepted solution, this works with objects & array of objects:

parseJsonAsQueryString = function (obj, prefix, objName) {
    var str = [];
    for (var p in obj) {
        if (obj.hasOwnProperty(p)) {
            var v = obj[p];
            if (typeof v == "object") {
                var k = (objName ? objName + '.' : '') + (prefix ? prefix + "[" + p + "]" : p);
                str.push(parseJsonAsQueryString(v, k));
            } else {
                var k = (objName ? objName + '.' : '') + (prefix ? prefix + '.' + p : p);
                str.push(encodeURIComponent(k) + "=" + encodeURIComponent(v));
                //str.push(k + "=" + v);
            }
        }
    }
    return str.join("&");
}

Also have added objName if you're using object parameters like in asp.net mvc action methods.

It doesn't know it's an array, that's why you have to supply delete[] instead of regular old delete.

.NET 4

string.Join(",", arr)

.NET earlier

string.Join(",", Array.ConvertAll(arr, x => x.ToString()))

$ENV{FOO} for usage, where FOO is being picked up from the environment variable. otherwise use as ${FOO}, where FOO is some other variable. For setting, SET(FOO "foo") would be used in CMake.

You can use your exception message by:-

 public class MyNullPointException extends NullPointerException {

        private ExceptionCodes exceptionCodesCode;

        public MyNullPointException(ExceptionCodes code) {
            this.exceptionCodesCode=code;
        }
        @Override
        public String getMessage() {
            return exceptionCodesCode.getCode();
        }


   public class enum ExceptionCodes {
    COULD_NOT_SAVE_RECORD ("cityId:001(could.not.save.record)"),
    NULL_POINT_EXCEPTION_RECORD ("cityId:002(null.point.exception.record)"),
    COULD_NOT_DELETE_RECORD ("cityId:003(could.not.delete.record)");

    private String code;

    private ExceptionCodes(String code) {
        this.code = code;
    }

    public String getCode() {
        return code;
    }
}

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

Had a similar need. $compile does the job. (Not completely sure if this is "THE" way to do it, still working my way through angular)

http://jsbin.com/ebuhuv/7/edit - my exploration test.

One thing to note (per my example), one of my requirements was that the template would change based on a type attribute once you clicked save, and the templates were very different. So though, you get the data binding, if need a new template in there, you will have to recompile.

An alternative solution, which is portable and with higher precision, available since C++11, is to use std::chrono.

Here is an example:

#include <iostream>
#include <chrono>
typedef std::chrono::high_resolution_clock Clock;

int main()
{
    auto t1 = Clock::now();
    auto t2 = Clock::now();
    std::cout << "Delta t2-t1: " 
              << std::chrono::duration_cast<std::chrono::nanoseconds>(t2 - t1).count()
              << " nanoseconds" << std::endl;
}

Running this on ideone.com gave me:

Delta t2-t1: 282 nanoseconds

Here is one of the most efficient way, it works smoothly:

https://github.com/MikeOrtiz/TouchImageView

Place TouchImageView.java in your project. It can then be used the same as ImageView.

Example:

TouchImageView img = (TouchImageView) findViewById(R.id.img);

If you are using TouchImageView in xml, then you must provide the full package name, because it is a custom view.

Example:

    <com.example.touch.TouchImageView
            android:id="@+id/img”
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

Use

rm -rf *

Update: The . stands for current directory, but we cannot use this. The command seems to have explicit checks for . and ... Use the wildcard globbing instead. But this can be risky.

A safer version IMO is to use:

rm -ri * 

(this prompts you for confirmation before deleting every file/directory.)

You can't do this with a UNIQUE constraint, but you can do this in a trigger.

    CREATE TRIGGER [dbo].[OnInsertMyTableTrigger]
   ON  [dbo].[MyTable]
   INSTEAD OF INSERT
AS 
BEGIN
    SET NOCOUNT ON;

    DECLARE @Column1 INT;
    DECLARE @Column2 INT; -- allow nulls on this column

    SELECT @Column1=Column1, @Column2=Column2 FROM inserted;

    -- Check if an existing record already exists, if not allow the insert.
    IF NOT EXISTS(SELECT * FROM dbo.MyTable WHERE Column1=@Column1 AND Column2=@Column2 @Column2 IS NOT NULL)
    BEGIN
        INSERT INTO dbo.MyTable (Column1, Column2)
            SELECT @Column2, @Column2;
    END
    ELSE
    BEGIN
        RAISERROR('The unique constraint applies on Column1 %d, AND Column2 %d, unless Column2 is NULL.', 16, 1, @Column1, @Column2);
        ROLLBACK TRANSACTION;   
    END

END

Here's a slightly different, but insightful take on why many features of C make sense: http://steve.yegge.googlepages.com/tour-de-babel#C

Basically, the standard CPU architecture is a Von Neumann architecture, and it's tremendously useful to be able to refer to the location of a data item in memory, and do arithmetic with it, on such a machine. If you know any variant of assembly language, you will quickly see how crucial this is at the low level.

C++ makes pointers a bit confusing, since it sometimes manages them for you and hides their effect in the form of "references." If you use straight C, the need for pointers is much more obvious: there's no other way to do call-by-reference, it's the best way to store a string, it's the best way to iterate through an array, etc.

This doesn't exactly answer the question as posed, but it does create the same visual effect that you are trying to achieve.

Update: use IntersectionObserver

The best method I have found so far is the jQuery appear plugin. Works like a charm.

Mimics a custom "appear" event, which fires when an element scrolls into view or otherwise becomes visible to the user.

$('#foo').appear(function() {
  $(this).text('Hello world');
});

This plugin can be used to prevent unnecessary requests for content that's hidden or outside the viewable area.

Basically just target the ID of the select and do this:

var numberOfOptions = $('#selectId option').length;

This is one of those things that can be difficult to search for if you don't already know where to look.

[ is actually a command, not part of the bash shell syntax as you might expect. It happens to be a Bash built-in command, so it's documented in the Bash manual.

There's also an external command that does the same thing; on many systems, it's provided by the GNU Coreutils package.

[ is equivalent to the test command, except that [ requires ] as its last argument, and test does not.

Assuming the bash documentation is installed on your system, if you type info bash and search for 'test' or '[' (the apostrophes are part of the search), you'll find the documentation for the [ command, also known as the test command. If you use man bash instead of info bash, search for ^ *test (the word test at the beginning of a line, following some number of spaces).

Following the reference to "Bash Conditional Expressions" will lead you to the description of -ne, which is the numeric inequality operator ("ne" stands for "not equal). By contrast, != is the string inequality operator.

You can also find bash documentation on the web.

• Bash reference
• Bourne shell builtins (including test and [)
• Bash Conditional Expressions -- (Scroll to the bottom; -ne is under "arg1 OP arg2")
• POSIX documentation for test

The official definition of the test command is the POSIX standard (to which the bash implementation should conform reasonably well, perhaps with some extensions).

You most likely get this message when the project points to an old location of the assembly where it no longer exists. Since you were able to build it once, the assembly has already been copied into your bin\Debug / bin\Release folders so your project can still find a copy.

If you open the references node of the project in your solution explorer, there should be a yellow icon next to the reference. Remove the reference and add it again from the correct location.

If you want to know the location it was referenced from, you'd have to open the .csproj file in a text editor and look for the HintPath for that assembly - the IDE for some reason does not show this information.

Within the script:

var scripts = document.getElementsByTagName("script"),
    src = scripts[scripts.length-1].src;

This works because the browser loads and executes scripts in order, so while your script is executing, the document it was included in is sure to have your script element as the last one on the page. This code of course must be 'global' to the script, so save src somewhere where you can use it later. Avoid leaking global variables by wrapping it in:

(function() { ... })();

Most of my XML parsing life is spent extracting nuggets of useful information out of truckloads of XML (Amazon MWS). As such, my answer assumes you want only specific information and you know where it is located.

I find the easiest way to use XMLReader is to know which tags I want the information out of and use them. If you know the structure of the XML and it has lots of unique tags, I find that using the first case is the easy. Cases 2 and 3 are just to show you how it can be done for more complex tags. This is extremely fast; I have a discussion of speed over on What is the fastest XML parser in PHP?

The most important thing to remember when doing tag-based parsing like this is to use if ($myXML->nodeType == XMLReader::ELEMENT) {... - which checks to be sure we're only dealing with opening nodes and not whitespace or closing nodes or whatever.

function parseMyXML ($xml) { //pass in an XML string
    $myXML = new XMLReader();
    $myXML->xml($xml);

    while ($myXML->read()) { //start reading.
        if ($myXML->nodeType == XMLReader::ELEMENT) { //only opening tags.
            $tag = $myXML->name; //make $tag contain the name of the tag
            switch ($tag) {
                case 'Tag1': //this tag contains no child elements, only the content we need. And it's unique.
                    $variable = $myXML->readInnerXML(); //now variable contains the contents of tag1
                    break;

                case 'Tag2': //this tag contains child elements, of which we only want one.
                    while($myXML->read()) { //so we tell it to keep reading
                        if ($myXML->nodeType == XMLReader::ELEMENT && $myXML->name === 'Amount') { // and when it finds the amount tag...
                            $variable2 = $myXML->readInnerXML(); //...put it in $variable2. 
                            break;
                        }
                    }
                    break;

                case 'Tag3': //tag3 also has children, which are not unique, but we need two of the children this time.
                    while($myXML->read()) {
                        if ($myXML->nodeType == XMLReader::ELEMENT && $myXML->name === 'Amount') {
                            $variable3 = $myXML->readInnerXML();
                            break;
                        } else if ($myXML->nodeType == XMLReader::ELEMENT && $myXML->name === 'Currency') {
                            $variable4 = $myXML->readInnerXML();
                            break;
                        }
                    }
                    break;

            }
        }
    }
$myXML->close();
}

To create list of lists, you need to separate them with commas, like this

coin_args = [
    ["pennies", '2.5', '50.0', '.01'],
    ["nickles", '5.0', '40.0', '.05'],
    ["dimes", '2.268', '50.0', '.1'],
    ["quarters", '5.67', '40.0', '.25']
]

I ran into this error because I was trying to pass in a date from localStorage. Passing the date into a new Date object, and then calling .toISOString() did the trick for me:

const dateFromStorage = localStorage.getItem('someDate');
const date = new Date(dateFromStorage);
const momentDate = moment(date.toISOString());

This suppressed any warnings in the console.

Simply declare this code to get device width

let deviceWidth = Dimensions.get('window').width

Maybe it's obviously but, Dimensions is an react-native import

import { Dimensions } from 'react-native'

Dimensions will not work without that

Sometimes vertical-align needs two inline (span, label, input, etc...) elements next to each other to work properly. The following checkboxes are properly vertically centered in IE, Safari, FF, and Chrome, even if the text size is very small or large.

They all float next to each other on the same line, but the nowrap means that the whole label text always stays next to the checkbox.

The downside is the extra meaningless SPAN tags.

.checkboxes label {_x000D_
  display: inline-block;_x000D_
  padding-right: 10px;_x000D_
  white-space: nowrap;_x000D_
}_x000D_
.checkboxes input {_x000D_
  vertical-align: middle;_x000D_
}_x000D_
.checkboxes label span {_x000D_
  vertical-align: middle;_x000D_
}

<form>_x000D_
  <div class="checkboxes">_x000D_
    <label for="x"><input type="checkbox" id="x" /> <span>Label text x</span></label>_x000D_
    <label for="y"><input type="checkbox" id="y" /> <span>Label text y</span></label>_x000D_
    <label for="z"><input type="checkbox" id="z" /> <span>Label text z</span></label>_x000D_
  </div>_x000D_
</form>

Now, if you had a very long label text that needed to wrap without wrapping under the checkbox, you'd use padding and negative text indent on the label elements:

.checkboxes label {_x000D_
  display: block;_x000D_
  padding-right: 10px;_x000D_
  padding-left: 22px;_x000D_
  text-indent: -22px;_x000D_
}_x000D_
.checkboxes input {_x000D_
  vertical-align: middle;_x000D_
}_x000D_
.checkboxes label span {_x000D_
  vertical-align: middle;_x000D_
}

<form>_x000D_
  <div class="checkboxes">_x000D_
    <label for="x"><input type="checkbox" id="x" /> <span>Label text x so long that it will probably wrap so let's see how it goes with the proposed CSS (expected: two lines are aligned nicely)</span></label>_x000D_
    <label for="y"><input type="checkbox" id="y" /> <span>Label text y</span></label>_x000D_
    <label for="z"><input type="checkbox" id="z" /> <span>Label text z</span></label>_x000D_
  </div>_x000D_
</form>

As I understand, if have id's: 1,2,4,5 it should return 3.

SELECT t1.id + 1
FROM theTable t1
WHERE NOT EXISTS (
    SELECT * 
    FROM theTable t2
    WHERE t2.id = t1.id + 1
)
LIMIT 1

What is happening is that stock_list.toArray() is creating an Object[] rather than a String[] and hence the typecast is failing¹.

The correct code would be:

  String [] stockArr = stockList.toArray(new String[stockList.size()]);

or even

  String [] stockArr = stockList.toArray(new String[0]);

For more details, refer to the javadocs for the two overloads of List.toArray.

The latter version uses the zero-length array to determine the type of the result array. (Surprisingly, it is faster to do this than to preallocate ... at least, for recent Java releases. See https://stackoverflow.com/a/4042464/139985 for details.)

From a technical perspective, the reason for this API behavior / design is that an implementation of the List<T>.toArray() method has no information of what the <T> is at runtime. All it knows is that the raw element type is Object. By contrast, in the other case, the array parameter gives the base type of the array. (If the supplied array is big enough to hold the list elements, it is used. Otherwise a new array of the same type and a larger size is allocated and returned as the result.)

^{1 - In Java, an Object[] is not assignment compatible with a String[]. If it was, then you could do this:}

    Object[] objects = new Object[]{new Cat("fluffy")};
    Dog[] dogs = (Dog[]) objects;
    Dog d = dogs[0];     // Huh???

^{This is clearly nonsense, and that is why array types are not generally assignment compatible.}

 <div onScrollCapture={() => this._onScrollEvent()}></div>

 _onScrollEvent = (e)=>{
     const top = e.nativeEvent.target.scrollTop;
     console.log(top); 
}

This works fine for 2 tables. I have 3 tables and on clause has to link 2 conditions from 3 tables. My code:

from p in _dbContext.Products join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId join jpr in leftJoinQuery on new { VariantId = pv.Vid, ProductId = p.ProduktId } equals new { VariantId = jpr.Prices.VariantID, ProductId = jpr.Prices.ProduktID } into lj

But its showing error at this point: join pv in _dbContext.ProductVariants on p.ProduktId equals pv.ProduktId

Error: The type of one of the expressions in the join clause is incorrect. Type inference failed in the call to 'GroupJoin'.

There is a simple technique to handle this.

Code:

number=[1,2,3,4,5,6] #Original list
another=[] #another empty list
for a in number: #here I am declaring variable (a) as an item in the list (number)
    another.append(a) #here we are adding the items of list (number) to list (another)
print(another)

Output:

>>> [1,2,3,4,5,6]

I hope this was useful for your query.

What you could do is copy the code from tkinter.py into a file called mytkinter.py, then do this code:

import tkinter, mytkinter
root = tkinter.Tk()
window = mytkinter.Tk()
button = mytkinter.Button(window, text="Search", width = 7,
                               command=cmd)
button2 = tkinter.Button(root, text="Search", width = 7,
                               command=cmdtwo)

And you have two windows which don't collide!

This is a security update. If an attacker can modify some file in the web server (the JS one, for example), he can make every loaded pages to download another script (for example to keylog your password or steal your SessionID and send it to his own server).

To avoid it, the browser check the Same-origin policy

Your problem is that the browser is trying to load something with your script (with an Ajax request) that is on another domain (or subdomain). To avoid it (if it is on your own website) you can:

• Copy the element on your own server (but it will be static).
• You can change your HTTP header to accept Cross-Origin content. See the Access-Control-Allow-Origin documentation for more information.

You can also do:

echo "hello
world"

This works both inside a script and from the command line.
In the command line, press Shift+Enter to do the line breaks inside the string.

This works for me on my macOS and my Ubuntu 18.04

filter expects to get a function and something that it can iterate over. The function should return True or False for each element in the iterable. In your particular example, what you're looking to do is something like the following:

In [47]: def greetings(x):
   ....:     return x == "hello"
   ....:

In [48]: filter(greetings, ["hello", "goodbye"])
Out[48]: ['hello']

Note that in Python 3, it may be necessary to use list(filter(greetings, ["hello", "goodbye"])) to get this same result.

You can easily do that using an async wait method in javascript.

Below is an example retrieving a WebRTC promise value using a timeout.

function await_getipv4(timeout = 1000) {_x000D_
    var t1 = new Date();_x000D_
    while(!window.ipv4) {_x000D_
        var stop = new Date() - t1 >= timeout;_x000D_
        if(stop) {_x000D_
            console.error('timeout exceeded for await_getipv4.');_x000D_
            return false;_x000D_
        }_x000D_
    }_x000D_
    return window.ipv4;_x000D_
}_x000D_
_x000D_
function async_getipv4() {_x000D_
    var ipv4 = null;_x000D_
    var findIP = new Promise(r=>{var w=window,a=new (w.RTCPeerConnection||w.mozRTCPeerConnection||w.webkitRTCPeerConnection)({iceServers:[]}),b=()=>{};a.createDataChannel("");a.createOffer(c=>a.setLocalDescription(c,b,b),b);a.onicecandidate=c=>{try{c.candidate.candidate.match(/([0-9]{1,3}(\.[0-9]{1,3}){3}|[a-f0-9]{1,4}(:[a-f0-9]{1,4}){7})/g).forEach(r)}catch(e){}}})_x000D_
    findIP.then(ip => window.ipv4 = ip);_x000D_
    return await_getipv4();_x000D_
};

To create a new branch without committing on master, you can use:

git checkout -b <branchname>

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

UPD 19.03.2019 Here is a version for browser on GitHub.

What you want to do is a bad idea. It would require you to embed your username and password in the app. This is a very bad idea as it might be possible to reverse engineer your APK and get the username and password to this publicly facing mysql server which may contain sensitive user data.

I would suggest making a web service to act as a proxy to the mysql server. I assume users need to be logged in, so you could use their username/password to authenticate to the web service.

You can use pop():

x=[2,3,4,5,6,7]
print(x.pop(2))

output is 4

This should do the trick:

window.onload = function(event) {
    event.stopPropagation(true);
    window.location.href="http://www.google.com";
};

Good luck  ;)

pytest test_name.py -v -s

Simple!

Just wanted to provide a different option for this. In my case, I usually work on my individual branches then merge to master, and the individual commits I do to my local are not that important.

Due to a git hook that checks for the appropriate ticket number on Jira but was case sensitive, I was prevented from pushing my code. Also, the commit was done long ago and I didn't want to count how many commits to go back on the rebase.

So what I did was to create a new branch from latest master and squash all commits from problem branch into a single commit on new branch. It was easier for me and I think it's good idea to have it here as future reference.

From latest master:

git checkout -b new-branch

Then

git merge --squash problem-branch
git commit -m "new message"

You can use either h() or html_escape(), but most people use h() by convention. h() is short for html_escape() in rails.

In your controller:

@stuff = "<b>Hello World!</b>"

In your view:

<%=h @stuff %>

If you view the HTML source: you will see the output without actually bolding the data. I.e. it is encoded as <b>Hello World!</b>.

It will appear an be displayed as <b>Hello World!</b>

As you are using asp:Button which is a server control, post back will happen to avoid that go for html button,

asp:Button .... />

Type to

input type="button" .... />

Hope this answer will help,Multiple Value Filter

And working example in this fiddle

arrayOfObjectswithKeys | filterMultiple:{key1:['value1','value2','value3',...etc],key2:'value4',key3:[value5,value6,...etc]}

If I had to guess, you did this:

import datetime

at the top of your code. This means that you have to do this:

datetime.datetime.strptime(date, "%Y-%m-%d")

to access the strptime method. Or, you could change the import statement to this:

from datetime import datetime

and access it as you are.

The people who made the datetime module also named their class datetime:

#module  class    method
datetime.datetime.strptime(date, "%Y-%m-%d")

Another approach, that doesn't involve adding columns to the result, is to simply zero-out the day component of the date, so 2016-07-13 and 2016-07-16 would both be 2016-07-01 - thus making them equal by month.

If you have a date (not a datetime) value, then you can zero it directly:

SELECT
    DATEADD( day, 1 - DATEPART( day, [Date] ), [Date] ),
    COUNT(*)
FROM
    [Table]
GROUP BY
    DATEADD( day, 1 - DATEPART( day, [Date] ), [Date] )

If you have datetime values, you'll need to use CONVERT to remove the time-of-day portion:

SELECT
    DATEADD( day, 1 - DATEPART( day, [Date] ),  CONVERT( date, [Date] ) ),
    COUNT(*)
FROM
    [Table]
GROUP BY
    DATEADD( day, 1 - DATEPART( day, [Date] ),  CONVERT( date, [Date] ) )

What is the right approach for doing this?

There are a lot of "right" approaches, you just have decide which one best suites your needs. It appears as though you're misunderstanding how to use node_modules...

If you're familiar with NuGet you should think of npm as its client-side counterpart. Where the node_modules directory is like the bin directory for NuGet. The idea is that this directory is just a common location for storing packages, in my opinion it is better to take a dependency on the packages you need as you have done in the package.json. Then use a task runner like Gulp for example to copy the files you need into your desired wwwroot location.

I wrote a blog post about this back in January that details npm, Gulp and a whole bunch of other details that are still relevant today. Additionally, someone called attention to my SO question I asked and ultimately answered myself here, which is probably helpful.

I created a Gist that shows the gulpfile.js as an example.

In your Startup.cs it is still important to use static files:

app.UseStaticFiles();

This will ensure that your application can access what it needs.

Very simply:

.service - registered function will be invoked as a constructor (aka 'newed')

.factory - registered function will be invoked as a simple function

Both get invoked once resulting in a singleton object that gets injected into other components of your app.

Replace '\n' with "\n". The escape sequence is not recognized when you use '.

See the manual.

For the question of how to write line endings, see the note here. Basically, different operating systems have different conventions for line endings. Windows uses "\r\n", unix based operating systems use "\n". You should stick to one convention (I'd chose "\n") and open your file in binary mode (fopen should get "wb", not "w").

Lazy Set

VARIABLE = value

Normal setting of a variable, but any other variables mentioned with the value field are recursively expanded with their value at the point at which the variable is used, not the one it had when it was declared

Immediate Set

VARIABLE := value

Setting of a variable with simple expansion of the values inside - values within it are expanded at declaration time.

Lazy Set If Absent

VARIABLE ?= value

Setting of a variable only if it doesn't have a value. value is always evaluated when VARIABLE is accessed. It is equivalent to

ifeq ($(origin FOO), undefined)

Append

VARIABLE += value

Appending the supplied value to the existing value (or setting to that value if the variable didn't exist)

Check out the "--only-keep-debug" option of the strip command.

From the link:

The intention is that this option will be used in conjunction with --add-gnu-debuglink to create a two part executable. One a stripped binary which will occupy less space in RAM and in a distribution and the second a debugging information file which is only needed if debugging abilities are required.

Unless you are writing directly to the slave (Server2) the only problem should be that Server2 is missing any updates that have happened since it was disconnected. Simply restarting the slave with "START SLAVE;" should get everything back up to speed.

Set your onClickListeners on onBindViewHolder() and you can access the position from there. If you set them in your ViewHolder you won't know what position was clicked unless you also pass the position into the ViewHolder

EDIT

As pskink pointed out ViewHolder has a getPosition() so the way you were originally doing it was correct.

When the view is clicked you can use getPosition() in your ViewHolder and it returns the position

Update

getPosition() is now deprecated and replaced with getAdapterPosition()

Update 2020

getAdapterPosition() is now deprecated and replaced with getAbsoluteAdapterPosition() or getBindingAdapterPosition()

Kotlin code:

override fun onBindViewHolder(holder: MyHolder, position: Int) {
        // - get element from your dataset at this position
        val item = myDataset.get(holder.absoluteAdapterPosition)
    }

Javascript inheritance seems to be like an open debate everywhere. It can be called "The curious case of Javascript language".

The idea is that there is a base class and then you extend the base class to get an inheritance-like feature (not completely, but still).

The whole idea is to get what prototype really means. I did not get it until I saw John Resig's code (close to what jQuery.extend does) wrote a code chunk that does it and he claims that base2 and prototype libraries were the source of inspiration.

Here is the code.

    /* Simple JavaScript Inheritance
     * By John Resig http://ejohn.org/
     * MIT Licensed.
     */  
     // Inspired by base2 and Prototype
    (function(){
  var initializing = false, fnTest = /xyz/.test(function(){xyz;}) ? /\b_super\b/ : /.*/;

  // The base Class implementation (does nothing)
  this.Class = function(){};

  // Create a new Class that inherits from this class
  Class.extend = function(prop) {
    var _super = this.prototype;

    // Instantiate a base class (but only create the instance,
    // don't run the init constructor)
    initializing = true;
    var prototype = new this();
    initializing = false;

    // Copy the properties over onto the new prototype
    for (var name in prop) {
      // Check if we're overwriting an existing function
      prototype[name] = typeof prop[name] == "function" &&
        typeof _super[name] == "function" && fnTest.test(prop[name]) ?
        (function(name, fn){
          return function() {
            var tmp = this._super;

            // Add a new ._super() method that is the same method
            // but on the super-class
            this._super = _super[name];

            // The method only need to be bound temporarily, so we
            // remove it when we're done executing
            var ret = fn.apply(this, arguments);        
            this._super = tmp;

            return ret;
          };
        })(name, prop[name]) :
        prop[name];
    }

    // The dummy class constructor
    function Class() {
      // All construction is actually done in the init method
      if ( !initializing && this.init )
        this.init.apply(this, arguments);
    }

    // Populate our constructed prototype object
    Class.prototype = prototype;

    // Enforce the constructor to be what we expect
    Class.prototype.constructor = Class;

    // And make this class extendable
    Class.extend = arguments.callee;

    return Class;
  };
})();

There are three parts which are doing the job. First, you loop through the properties and add them to the instance. After that, you create a constructor for later to be added to the object.Now, the key lines are:

// Populate our constructed prototype object
Class.prototype = prototype;

// Enforce the constructor to be what we expect
Class.prototype.constructor = Class;

You first point the Class.prototype to the desired prototype. Now, the whole object has changed meaning that you need to force the layout back to its own one.

And the usage example:

var Car = Class.Extend({
  setColor: function(clr){
    color = clr;
  }
});

var volvo = Car.Extend({
   getColor: function () {
      return color;
   }
});

Very sort cut and effective solution is below:-

Add the below rule in your tsconfig.json file:-

"noImplicitAny": false

Then restart your project.

Try this, should work.

val list = List(1,2,4,2,4,7,3,2,4)
list.count(_==2) 

It will return 3

Using MySql and Entity framework code first Approach:

public class Vw_EMIcount
{
    public int EmiCount { get; set; }
    public string Satus { get; set; }
}

var result = context.Database.SqlQuery<Vw_EMIcount>("call EMIStatus('2018-3-01' ,'2019-05-30')").ToList();

<?php
$file = fopen("members.txt", "r");
$members = array();

while (!feof($file)) {
   $members[] = fgets($file);
}

fclose($file);

var_dump($members);
?>

For cmake version 3.1.0-rc2 to pick up boost 1.57 specify -D_boost_TEST_VERSIONS=1.57

cmake version 3.1.0-rc2 defaults to boost<=1.56.0 as is seen using -DBoost_DEBUG=ON

cmake -D_boost_TEST_VERSIONS=1.57 -DBoost_DEBUG=ON -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++

I have another solution for your question .

In the first when use date the output is like this :

Thu 28 Jan 2021 22:29:40 IST

Then if you want only to show current time in hours and minutes you can use this command :

date | cut -d " " -f5 | cut -d ":" -f1-2 

Then the output :

22:29

When you use git push origin :staleStuff, it automatically removes origin/staleStuff, so when you ran git remote prune origin, you have pruned some branch that was removed by someone else. It's more likely that your co-workers now need to run git prune to get rid of branches you have removed.

So what exactly git remote prune does? Main idea: local branches (not tracking branches) are not touched by git remote prune command and should be removed manually.

Now, a real-world example for better understanding:

You have a remote repository with 2 branches: master and feature. Let's assume that you are working on both branches, so as a result you have these references in your local repository (full reference names are given to avoid any confusion):

• refs/heads/master (short name master)
• refs/heads/feature (short name feature)
• refs/remotes/origin/master (short name origin/master)
• refs/remotes/origin/feature (short name origin/feature)

Now, a typical scenario:

1. Some other developer finishes all work on the feature, merges it into master and removes feature branch from remote repository.
2. By default, when you do git fetch (or git pull), no references are removed from your local repository, so you still have all those 4 references.
3. You decide to clean them up, and run git remote prune origin.
4. git detects that feature branch no longer exists, so refs/remotes/origin/feature is a stale branch which should be removed.
5. Now you have 3 references, including refs/heads/feature, because git remote prune does not remove any refs/heads/* references.

It is possible to identify local branches, associated with remote tracking branches, by branch.<branch_name>.merge configuration parameter. This parameter is not really required for anything to work (probably except git pull), so it might be missing.

(updated with example & useful info from comments)

When your browser redirects the user to Google's oAuth page, are you passing as a parameter the redirect URI you want Google's server to return to with the token response? Setting a redirect URI in the console is not a way of telling Google where to go when a login attempt comes in, but rather it's a way of telling Google what the allowed redirect URIs are (so if someone else writes a web app with your client ID but a different redirect URI it will be disallowed); your web app should, when someone clicks the "login" button, send the browser to:

https://accounts.google.com/o/oauth2/auth?client_id=XXXXX&redirect_uri=http://localhost:8080/WEBAPP/youtube-callback.html&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload

(the callback URI passed as a parameter must be url-encoded, btw).

When Google's server gets authorization from the user, then, it'll redirect the browser to whatever you sent in as the redirect_uri. It'll include in that request the token as a parameter, so your callback page can then validate the token, get an access token, and move on to the other parts of your app.

If you visit:

http://code.google.com/p/google-api-java-client/wiki/OAuth2#Authorization_Code_Flow

You can see better samples of the java client there, demonstrating that you have to override the getRedirectUri method to specify your callback path so the default isn't used.

The redirect URIs are in the client_secrets.json file for multiple reasons ... one big one is so that the oAuth flow can verify that the redirect your app specifies matches what your app allows.

If you visit https://developers.google.com/api-client-library/java/apis/youtube/v3 You can generate a sample application for yourself that's based directly off your app in the console, in which (again) the getRedirectUri method is overwritten to use your specific callbacks.

Specify POST method in form
<form name="registrationform" action="register.php" method="post">


your form code

</form>

You can set the path variable for easily by command prompt.

1. Open run and write cmd

2. In the command window write the following: set path=%path%;C:\python36

3. press enter.
4. to check write python and enter. You will see the python version as shown in the picture.

var value1=$("id1").val();
var value2=$("id2").val();
data:"{'data1':'"+value1+"','data2':'"+value2+"'}"

Right_click on the drawable and create new layout xml file in the name of for example button_background.xml. then copy and paste the following code. You can change it according your need.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners
android:radius="14dp" />
<solid android:color="@color/colorButton" />
<padding
android:bottom="0dp"
android:left="0dp"
android:right="0dp"
android:top="0dp" />
<size
android:width="120dp"
android:height="40dp" />
</shape>

Now you can use it.

<Button
android:background="@drawable/button_background"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>

I had the same problem minutes ago. I've mentioned changing the 'deployment target' fixed my problem.

You want a check constraint.

CHECK constraints determine the valid values from a logical expression that is not based on data in another column. For example, the range of values for a salary column can be limited by creating a CHECK constraint that allows for only data that ranges from $15,000 through $100,000. This prevents salaries from being entered beyond the regular salary range.

You want something like:

ALTER TABLE dbo.Table ADD CONSTRAINT CK_Table_Frequency
    CHECK (Frequency IN ('Daily', 'Weekly', 'Monthly', 'Yearly'))

You can also implement check constraints with scalar functions, as described in the link above, which is how I prefer to do it.

I second opinions that you should choose the iteration method according to your need. I would suggest you actually not to ever loop through native Array with for in structure. It is way slower and, as Chase Seibert pointed at the moment ago, not compatible with Prototype framework.

There is an excellent benchmark on different looping styles that you absolutely should take a look at if you work with JavaScript. Do not do early optimizations, but you should keep that stuff somewhere in the back of your head.

I would use for in to get all properties of an object, which is especially useful when debugging your scripts. For example, I like to have this line handy when I explore unfamiliar object:

l = ''; for (m in obj) { l += m + ' => ' + obj[m] + '\n' } console.log(l);

It dumps content of the whole object (together with method bodies) to my Firebug log. Very handy.

Here is a function to convert seconds to hh-mm-ss format based on powtac's answer here

jsfiddle

/** 
 * Convert seconds to hh-mm-ss format.
 * @param {number} totalSeconds - the total seconds to convert to hh- mm-ss
**/
var SecondsTohhmmss = function(totalSeconds) {
  var hours   = Math.floor(totalSeconds / 3600);
  var minutes = Math.floor((totalSeconds - (hours * 3600)) / 60);
  var seconds = totalSeconds - (hours * 3600) - (minutes * 60);

  // round seconds
  seconds = Math.round(seconds * 100) / 100

  var result = (hours < 10 ? "0" + hours : hours);
      result += "-" + (minutes < 10 ? "0" + minutes : minutes);
      result += "-" + (seconds  < 10 ? "0" + seconds : seconds);
  return result;
}

Example use

var seconds = SecondsTohhmmss(70);
console.log(seconds);
// logs 00-01-10

Thanks @crea1

A small variant:

As it is written on https://git-scm.com/docs/git-config#_includes:

If the pattern ends with /, ** will be automatically added. For example, the pattern foo/ becomes foo/**. In other words, it matches foo and everything inside, recursively.

So I use in my case,
~/.gitconfig :

[user] # as default, personal needs
    email = [email protected]
    name = bcag2
[includeIf "gitdir:~/workspace/"] # job needs, like workspace/* so all included projects
    path = .gitconfig-job

# all others section: core, alias, log…

So If the project directory is in my ~/wokspace/, default user settings is replace with
~/.gitconfig-job :

[user]
name = John Smith
email = [email protected]

For Linux Python users:

import webbrowser
browser = webbrowser.get('google-chrome --allow-file-access-from-files %s')
browser.open(url)

In my case the 1 MB maximum cap for data transport by Intent. I'll just use Cache or Storage.

You can use the -B option.

Man page of df:

-B, --block-size=SIZE use SIZE-byte blocks

All together,

df -BG

On windows, nearly all AMPP (Apache,MySQL,PHP,PHPmyAdmin) packages don't include a mail server (but nearly all naked linuxes do have!). So, when using PHP under windows, you need to setup a mail server!

Imo the best and most simple tool ist this: http://smtp4dev.codeplex.com/

SMTP4Dev is a simple one-file mail server tool that does collect the mails it send (so it does not really sends mail, it just keeps them for development). Perfect tool.

@Skelly 's answer is correct. It won't let me add a comment (<50 rep)... but to answer your question on his answer: In the example he linked, if you add

col-xs-3 

class to each of the thumbnails, like this:

class="col-md-3 col-xs-3"

then it should stay the way you want it when sized down to phone width.

You can use this way to remove your remote branch

git remote remove <your remote branch name>

I use GNU Cash and it uses Open Financial Exchange (ofx) http://www.ofx.net/ to download complete transactions and balances from each account of each bank.

Let me emphasize that again, you get a huge list of transactions with OFX into the GNU Cash. Depending on the account type these transactions can be very detailed description of your transactions (purchases+paycheques), investments, interests, etc.

In my case, even though I have Chase debit card I had to choose Chase Credit to make it work. But Chase wants you to enable this OFX feature by logging into your online banking and enable Quicken/MS Money/etc. somewhere in your profile or preferences. Don't call Chase customer support because they know nothing about it.

This service for OFX and GNU Cash is free. I have heard that they charge $10 a month for other platforms.

OFX can download transactions from 348 banks so far. http://www.ofxhome.com/index.php/home/directory

Actualy, OFX also supports making bill payments, stop a check, intrabank and interbank transfers etc. It is quite extensive. See it here: http://ofx.net/AboutOFX/ServicesSupported.aspx

I agree that it's counterintuitive at first, but there's a good reason. Join can't be a method of a list because:

• it must work for different iterables too (tuples, generators, etc.)
• it must have different behavior between different types of strings.

There are actually two join methods (Python 3.0):

>>> b"".join
<built-in method join of bytes object at 0x00A46800>
>>> "".join
<built-in method join of str object at 0x00A28D40>

If join was a method of a list, then it would have to inspect its arguments to decide which one of them to call. And you can't join byte and str together, so the way they have it now makes sense.

Hide it with css and use a custom button with $(selector).click() to activate the the browse button. then set an interval to check the value of the file input type. the interval can display the value for the user so the user can see whats getting uploaded. the interval will clear when the form is submitted [EDIT] Sorry i have been very busy was meaning to update this post, here is an example

<form action="uploadScript.php" method="post" enctype="multipart/form-data">
<div>
    <!-- filename to display to the user -->
    <p id="file-name" class="margin-10 bold-10"></p>

    <!-- Hide this from the users view with css display:none; -->
    <input class="display-none" id="file-type" type="file" size="4" name="file"/>

    <!-- Style this button with type image or css whatever you wish -->
    <input id="browse-click" type="button" class="button" value="Browse for files"/>

    <!-- submit button -->
    <input type="submit" class="button" value="Change"/>
</div>

$(window).load(function () {
    var intervalFunc = function () {
        $('#file-name').html($('#file-type').val());
    };
    $('#browse-click').on('click', function () { // use .live() for older versions of jQuery
        $('#file-type').click();
        setInterval(intervalFunc, 1);
        return false;
    });
});

You can use the hasClass method, eg.

$('li.menu').hasClass('active') // true|false

Or if you want to select it in one go, you can use:

$('li.menu.active')

I'm very late to this game, but my problem started when I upgraded php on my server. I was able to just remove the .socket file and restart my services. Then, everything worked. Not sure why it made a difference, since the file is size 0 and the ownership and permissions are the same, but it worked.

Although this post is very old. In case if somebody is looking for this..

Guava facilitates partitioning the List into sublists of a specified size

List<Integer> intList = Lists.newArrayList(1, 2, 3, 4, 5, 6, 7, 8);
    List<List<Integer>> subSets = Lists.partition(intList, 3);

boolean containsWhitespace = false;
for (int i = 0; i < text.length() && !containsWhitespace; i++) {
    if (Character.isWhitespace(text.charAt(i)) {
        containsWhitespace = true;
    }
}
return containsWhitespace;

or, using Guava,

boolean containsWhitespace = CharMatcher.WHITESPACE.matchesAnyOf(text);

Simple clean-and-build seemed to fix it for me.

What worked for me was disabling the position: fixed; CSS.

This doesn't seem to work in Mac Excel 2016. After a bit of digging, it looks like the key combination for entering the array formula has changed from ?+RETURN to CTRL+SHIFT+RETURN.

UPDATE Table1 SET col1= col2 FROM (SELECT col2, col3 FROM Table2) as newTbl WHERE col4= col3

Here col4 & col1 are in Table1. col2 & col3 are in Table2
I Am trying to update each col1 where col4 = col3 different value for each row

You need to ensure your environment is properly setup in Eclipse so it knows the paths to your includes. Otherwise, it underlines them as not found.

The Resource Exception means there is an error with your resources, any resource folder file is corrupted, try to open all images in drawable folder to see if these are opening fine.

There is a good command to check for corrupted resource pngs.

f -name "*.png" | xargs -L 1 -I{} file  -I {} | grep -v 'image/png; charset=binary$'

You could use overloads:

public static string BuildClause(List<string> l){...}

public static string BuildClause(List<int> l){...}

public static string BuildClause<T>(List<T> l){...}

Or you could inspect the type of the generic parameter:

Type listType = typeof(T);
if(listType == typeof(int)){...}

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

$unixtime_to_date = date('jS F Y h:i:s A (T)', $unixtime);

This should work to.

I have a Mac, but luckily this should work the same way:

pip is a command-line thing. You don't run it in python.

For example, on my Mac, I just say:

$pip install somelib

pretty easy!

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

TLDR;

use location.href or better use window.location.href;

However if you read this you will gain undeniable proof.

The truth is it's fine to use but why do things that are questionable. You should take the higher road and just do it the way that it probably should be done.

location = "#/mypath/otherside"
var sections = location.split('/')

This code is perfectly correct syntax-wise, logic wise, type-wise you know the only thing wrong with it?

it has location instead of location.href

what about this

var mystring = location = "#/some/spa/route"

what is the value of mystring? does anyone really know without doing some test. No one knows what exactly will happen here. Hell I just wrote this and I don't even know what it does. location is an object but I am assigning a string will it pass the string or pass the location object. Lets say there is some answer to how this should be implemented. Can you guarantee all browsers will do the same thing?

This i can pretty much guess all browsers will handle the same.

var mystring = location.href = "#/some/spa/route"

What about if you place this into typescript will it break because the type compiler will say this is suppose to be an object?

This conversation is so much deeper than just the location object however. What this conversion is about what kind of programmer you want to be?

If you take this short-cut, yea it might be okay today, ye it might be okay tomorrow, hell it might be okay forever, but you sir are now a bad programmer. It won't be okay for you and it will fail you.

There will be more objects. There will be new syntax.

You might define a getter that takes only a string but returns an object and the worst part is you will think you are doing something correct, you might think you are brilliant for this clever method because people here have shamefully led you astray.

var Person.name = {first:"John":last:"Doe"}
console.log(Person.name) // "John Doe"

With getters and setters this code would actually work, but just because it can be done doesn't mean it's 'WISE' to do so.

Most people who are programming love to program and love to get better. Over the last few years I have gotten quite good and learn a lot. The most important thing I know now especially when you write Libraries is consistency and predictability.

Do the things that you can consistently do.

+"2" <-- this right here parses the string to a number. should you use it? or should you use parseInt("2")?

what about var num =+"2"?

From what you have learn, from the minds of stackoverflow i am not too hopefully.

If you start following these 2 words consistent and predictable. You will know the right answer to a ton of questions on stackoverflow.

Let me show you how this pays off. Normally I place ; on every line of javascript i write. I know it's more expressive. I know it's more clear. I have followed my rules. One day i decided not to. Why? Because so many people are telling me that it is not needed anymore and JavaScript can do without it. So what i decided to do this. Now because I have become sure of my self as a programmer (as you should enjoy the fruit of mastering a language) i wrote something very simple and i didn't check it. I erased one comma and I didn't think I needed to re-test for such a simple thing as removing one comma.

I wrote something similar to this in es6 and babel

var a = "hello world"
(async function(){
  //do work
})()

This code fail and took forever to figure out. For some reason what it saw was

var a = "hello world"(async function(){})()

hidden deep within the source code it was telling me "hello world" is not a function.

For more fun node doesn't show the source maps of transpiled code.

Wasted so much stupid time. I was presenting to someone as well about how ES6 is brilliant and then I had to start debugging and demonstrate how headache free and better ES6 is. Not convincing is it.

I hope this answered your question. This being an old question it's more for the future generation, people who are still learning.

Question when people say it doesn't matter either way works. Chances are a wiser more experienced person will tell you other wise.

what if someone overwrite the location object. They will do a shim for older browsers. It will get some new feature that needs to be shimmed and your 3 year old code will fail.

My last note to ponder upon.

Writing clean, clear purposeful code does something for your code that can't be answer with right or wrong. What it does is it make your code an enabler.

You can use more things plugins, Libraries with out fear of interruption between the codes.

for the record. use

window.location.href

As you can see in the documentation of JSHint you can change options per function or per file. In your case just place a comment in your file or even more local just in the function that uses eval:

/*jshint evil:true */

function helloEval(str) {
    /*jshint evil:true */
    eval(str);
}

Put sleep. It will work. I have tried. The reason is that the page wasn't loaded yet. Check this question to know how to wait for load - Wait for page load in Selenium

I had the same problem on Visual Studio Code. For various reasons several python versions are installed on my computer. I was thus able to easily solve the problem by switching python interpreter.

If like me you have several versions of python on you machine, in Visual Studio Code, you can easily change the interpreter by clicking on the bottom left corner where it says Python...

There are errors here :

var formTag = document.getElementsByTagName("form"), // form tag is an array
selectListItem = $('select'),
makeSelect = document.createElement('select'),
makeSelect.setAttribute("id", "groups");

The code must change to:

var formTag = document.getElementsByTagName("form");
var selectListItem = $('select');
var makeSelect = document.createElement('select');
makeSelect.setAttribute("id", "groups");

By the way, there is another error at line 129 :

var createLi.appendChild(createSubList);

Replace it with:

createLi.appendChild(createSubList);

Playbook to use it:

- hosts: all
  tasks:
  - template:
      src: templates/dump_variables
      dest: /tmp/ansible_variables
  - fetch:
      src: /tmp/ansible_variables
      dest: "{{inventory_hostname}}_ansible_variables"

After that you have a dump of all variables on every host, and a copy of each text dump file on your local workstation in your tmp folder. If you don't want local copies, you can remove the fetch statement.

This includes gathered facts, host variables and group variables. Therefore you see ansible default variables like group_names, inventory_hostname, ansible_ssh_host and so on.

Use element.style:

var element = document.createElement('select');
element.style.width = "100px";

The chosen answer above does not work.

Because typingTimer is occassionaly set multiple times (keyup pressed twice before keydown is triggered for fast typers etc.) then it doesn't clear properly.

The solution below solves this problem and will call X seconds after finished as the OP requested. It also no longer requires the redundant keydown function. I have also added a check so that your function call won't happen if your input is empty.

//setup before functions
var typingTimer;                //timer identifier
var doneTypingInterval = 5000;  //time in ms (5 seconds)

//on keyup, start the countdown
$('#myInput').keyup(function(){
    clearTimeout(typingTimer);
    if ($('#myInput').val()) {
        typingTimer = setTimeout(doneTyping, doneTypingInterval);
    }
});

//user is "finished typing," do something
function doneTyping () {
    //do something
}

And the same code in vanilla JavaScript solution:

//setup before functions
let typingTimer;                //timer identifier
let doneTypingInterval = 5000;  //time in ms (5 seconds)
let myInput = document.getElementById('myInput');

//on keyup, start the countdown
myInput.addEventListener('keyup', () => {
    clearTimeout(typingTimer);
    if (myInput.value) {
        typingTimer = setTimeout(doneTyping, doneTypingInterval);
    }
});

//user is "finished typing," do something
function doneTyping () {
    //do something
}

This solution does use ES6 but it's not necessary here. Just replace let with var and the arrow function with a regular function.

The proper way to determine the "type" of an object, which is a wobbly term in the Ruby world, is to call object.class.

Since classes can inherit from other classes, if you want to determine if an object is "of a particular type" you might call object.is_a?(ClassName) to see if object is of type ClassName or derived from it.

Normally type checking is not done in Ruby, but instead objects are assessed based on their ability to respond to particular methods, commonly called "Duck typing". In other words, if it responds to the methods you want, there's no reason to be particular about the type.

For example, object.is_a?(String) is too rigid since another class might implement methods that convert it into a string, or make it behave identically to how String behaves. object.respond_to?(:to_s) would be a better way to test that the object in question does what you want.
