Yet another approach is ISNULL().

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = ISNULL(@ABC, [ABC]),
    [ABCD] = ISNULL(@ABCD, [ABCD])

The difference between ISNULL and COALESCE is the return type. COALESCE can also take more than 2 arguments, and use the first that is not null. I.e.

select COALESCE(null, null, 1, 'two') --returns 1
select COALESCE(null, null, null, 'two') --returns 'two'

You should use $(document). It is a function trigger for any click event in the document. Then inside you can use the jquery on("click","body *",somefunction), where the second argument specifies which specific element to target. In this case every element inside the body.

$(document).on('click','body *',function(){
    //  $(this) = your current element that clicked.
    // additional code
});

Google released In-App Updates for the Play Core library.

I implemented a lightweight library to easily implement in-app updates. You can find to the following link an example about how to force the user to perform the update.

https://github.com/dnKaratzas/android-inapp-update#forced-updates

You can use

if (array == null || array.Length == 0)

OR

if (!(array != null && array.Length != 0))

NOTE!!!!! To insure that c# will implement the short circuit correctly; you have to compare that the object with NULL before you go to the children compare of the object.

C# 7.0 and above

if(!(array?.Length != 0))

For camera access use:

<key>NSCameraUsageDescription</key>
<string>Camera Access Warning</string>

Alternatively to SQL, you can do this in Microsoft SQL Server Management Studio, from the table Design Panel.

First Way

Slow double-click on the column. The column name will become an editable text box.

Second Way

SqlManagement Studio>>DataBases>>tables>>specificTable>>Column Folder>>Right Click on column>>Reman

Third Way

Table>>RightClick>>Design

You already get the next line in this line of your code:

 String line = sc.nextLine();  

To get the words of a line, I would recommend to use:

String[] words = line.split(" ");

Just another solution, this one's cross platform (uses java), and points you to the location of the jre.

java -XshowSettings:properties -version 2>&1 > /dev/null | grep 'java.home'

Outputs all of java's current settings, and finds the one called java.home.

For windows, you can go with findstr instead of grep.

java -XshowSettings:properties -version 2>&1 | findstr "java.home"

I think ForkJoinPool and related enhancement to Executor Framework is an important addition in Java 7.

your forget this in oninvalid, change your code with this:

    oninvalid="this.setCustomValidity('Lütfen isaretli yerleri doldurunuz')"

<form><input type="text" name="company_name"  oninvalid="this.setCustomValidity('Lütfen isaretli yerleri doldurunuz')" required /><input type="submit">_x000D_
</form>

Change to MyISAM engine and run this command

REPAIR TABLE tbl_name USE_FRM;

If:

• you want multiple, but not all, worksheets, and
• you want a single df as an output

Then, you can pass a list of worksheet names. Which you could populate manually:

import pandas as pd
    
path = "C:\\Path\\To\\Your\\Data\\"
file = "data.xlsx"
sheet_lst_wanted = ["01_SomeName","05_SomeName","12_SomeName"] # tab names from Excel

### import and compile data ###
    
# read all sheets from list into an ordered dictionary    
dict_temp = pd.read_excel(path+file, sheet_name= sheet_lst_wanted)

# concatenate the ordered dict items into a dataframe
df = pd.concat(dict_temp, axis=0, ignore_index=True)

OR

A bit of automation is possible if your desired worksheets have a common naming convention that also allows you to differentiate from unwanted sheets:

# substitute following block for the sheet_lst_wanted line in above block

import xlrd

# string common to only worksheets you want
str_like = "SomeName" 
    
### create list of sheet names in Excel file ###
xls = xlrd.open_workbook(path+file, on_demand=True)
sheet_lst = xls.sheet_names()
    
### create list of sheets meeting criteria  ###
sheet_lst_wanted = []
    
for s in sheet_lst:
    # note: following conditional statement based on my sheets ending with the string defined in sheet_like
    if s[-len(str_like):] == str_like:
        sheet_lst_wanted.append(s)
    else:
        pass

I used this method to change choosing Text Field

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

if ([textField isEqual:self.emailRegisterTextField]) {

    [self.usernameRegisterTextField becomeFirstResponder];

} else if ([textField isEqual:self.usernameRegisterTextField]) {

    [self.passwordRegisterTextField becomeFirstResponder];

} else {

    [textField resignFirstResponder];

    // To click button for registration when you clicking button "Done" on the keyboard
    [self createMyAccount:self.registrationButton];
}

return YES;

}

Mike's solution will just show the image, but any title set on the button will not be visible, because you can either set the title or the image.

If you want to set both (your image and title) use the following code:

btnImage = [UIImage imageNamed:@"image.png"];
[btnTwo setBackgroundImage:btnImage forState:UIControlStateNormal];
[btnTwo setTitle:@"Title" forState:UIControlStateNormal];

It appears to be a bug in React native that shadowOpacity is set to type CGFloat instead of float according to CALayer doc. use iPhone 5 simulator before it's fixed. (CGFloat is float in older devices. )

The React Native issue which is tracking this is:

I would have to agree with you. There are a lot of possibilities in django but best place to start is reviewing Django's design philosophy.

1. Calling an API from a model property would not be ideal, it seems like it would make more sense to do something like this in the view and possibly create a service layer to keep things dry. If the call to the API is non-blocking and the call is an expensive one, sending the request to a service worker (a worker that consumes from a queue) might make sense.

2. As per Django's design philosophy models encapsulate every aspect of an "object". So all business logic related to that object should live there:

Include all relevant domain logic

Models should encapsulate every aspect of an “object,” following Martin Fowler’s Active Record design pattern.

3. The side effects you describe are apparent, the logic here could be better broken down into Querysets and managers. Here is an example:

   models.py

   import datetime
   
   from djongo import models
   from django.db.models.query import QuerySet
   from django.contrib import admin
   from django.db import transaction
   
   
   class MyUser(models.Model):
   
       present_name = models.TextField(null=False, blank=True)
       status = models.TextField(null=False, blank=True)
       last_active = models.DateTimeField(auto_now=True, editable=False)
   
       # As mentioned you could put this in a template tag to pull it
       # from cache there. Depending on how it is used, it could be
       # retrieved from within the admin view or from a custom view
       # if that is the only place you will use it.
       #def get_present_name(self):
       #    # property became non-deterministic in terms of database
       #    # data is taken from another service by api
       #    return remote_api.request_user_name(self.uid) or 'Anonymous'
   
       # Moved to admin as an action
       # def activate(self):
       #     # method now has a side effect (send message to user)
       #     self.status = 'activated'
       #     self.save()
       #     # send email via email service
       #     #send_mail('Your account is activated!', '…', [self.email])
   
       class Meta:
           ordering = ['-id']  # Needed for DRF pagination
   
       def __unicode__(self):
           return '{}'.format(self.pk)
   
   
   class MyUserRegistrationQuerySet(QuerySet):
   
       def for_inactive_users(self):
           new_date = datetime.datetime.now() - datetime.timedelta(days=3*365)  # 3 Years ago
           return self.filter(last_active__lte=new_date.year)
   
       def by_user_id(self, user_ids):
           return self.filter(id__in=user_ids)
   
   
   class MyUserRegistrationManager(models.Manager):
   
       def get_query_set(self):
           return MyUserRegistrationQuerySet(self.model, using=self._db)
   
       def with_no_activity(self):
           return self.get_query_set().for_inactive_users()
   

   admin.py

   # Then in model admin
   
   class MyUserRegistrationAdmin(admin.ModelAdmin):
       actions = (
           'send_welcome_emails',
       )
   
       def send_activate_emails(self, request, queryset):
           rows_affected = 0
           for obj in queryset:
               with transaction.commit_on_success():
                   # send_email('welcome_email', request, obj) # send email via email service
                   obj.status = 'activated'
                   obj.save()
                   rows_affected += 1
   
           self.message_user(request, 'sent %d' % rows_affected)
   
   admin.site.register(MyUser, MyUserRegistrationAdmin)
   

I am following the same tuturial and I had this issue and how I solved is just download the

8.11.4 LTS version

from this link then install it then the command worked just fine!

This is what i did for rendering html files. And it solved the errors. Install consolidate and mustache by executing the below command in your project folder.

$ sudo npm install consolidate mustache --save

And make the following changes to your app.js file

var engine = require('consolidate');

app.set('views', __dirname + '/views');
app.engine('html', engine.mustache);
app.set('view engine', 'html');

And now html pages will be rendered properly.

Try something like the following if you want to use pure JavaScript:

document.getElementsByName('link')[0].placeholder='Type here to search';

to get localize your input use:

char sep = DecimalFormatSymbols.getInstance().getDecimalSeparator();

and then add:

textEdit.setKeyListener(DigitsKeyListener.getInstance("0123456789" + sep));

than don't forget to replace "," with "." so Float or Double can parse it without errors.

Google Compute Engine shows the SSH host key fingerprint in the serial output of a Linux instance. The API can get that data from GCE, and there is no need to log in to the instance.

I didn't find it anywhere else but from the serial output. I think the fingerprint should be in some more programmer-friendly place.

However, it seems that it depends on the type of an instance. I am using instances of Debian 7 (Wheezy) f1-micro.

On the Unity Editor open your project and:

1. Enable External option in Unity ? Preferences ? Packages ? Repository (only if Unity ver < 4.5)
2. Switch to Visible Meta Files in Edit ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Edit ? Project Settings ? Editor ? Asset Serialization Mode
4. Save Scene and Project from File menu.
5. Quit Unity and then you can delete the Library and Temp directory in the project directory. You can delete everything but keep the Assets and ProjectSettings directory.

If you already created your empty git repo on-line (eg. github.com) now it's time to upload your code. Open a command prompt and follow the next steps:

cd to/your/unity/project/folder

git init

git add *

git commit -m "First commit"

git remote add origin [email protected]:username/project.git

git push -u origin master

You should now open your Unity project while holding down the Option or the Left Alt key. This will force Unity to recreate the Library directory (this step might not be necessary since I've seen Unity recreating the Library directory even if you don't hold down any key).

Finally have git ignore the Library and Temp directories so that they won’t be pushed to the server. Add them to the .gitignore file and push the ignore to the server. Remember that you'll only commit the Assets and ProjectSettings directories.

And here's my own .gitignore recipe for my Unity projects:

# =============== #
# Unity generated #

UnityGenerated/

Assets/AssetStoreTools*

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

That its the correct code of background size :

<div class="html-mobile-background">
</div>

<style type="text/css">
html {
    /* Whatever you want */
}
.html-mobile-background {
    position: fixed;
    z-index: -1;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%; /* To compensate for mobile browser address bar space */
    background: url(YOUR BACKGROUND URL HERE) no-repeat; 
 center center fixed;

-o-background-size: cover;
background-size: cover;
 background-size: 100% 100%
}
</style>

for windows users: In case of you can't remove .lock file and it gives you the following:

And you know that eclipse is already closed, just open Task Manager then processes then end precess for all eclipse.exe occurrences in the processes list.

If you are using ConstraintLayout, just put the element after the other elements to make it on front than the others

environment.plst file loads first on MAC so put the path on it.

For 1st time use, use the following command

export PATH=$PATH: /path/to/set

You can use: Object.keys(obj)

Example:

var dictionary = {
  "cats": [1, 2, 37, 38, 40, 32, 33, 35, 39, 36],
  "dogs": [4, 5, 6, 3, 2]
};

// Get the keys
var keys = Object.keys(dictionary);

console.log(keys);

See reference below for browser support. It is supported in Firefox 4.20, Chrome 5, and Internet Explorer 9. Object.keys() contains a code snippet that you can add if Object.keys() is not supported in your browser.

Look to this, may be help you.

                  Text("Hello world!!"),
                  //You can add another children
            ]),
          ),
        );
      },
    );
  }
}

From the standpoint of a Checkpoint firewall, you will see a message from the firewall if you actually choose Reject as an Action thereby exposing to a propective attacker the presence of a firewall in front of the server. The firewall will silently drop all connections that doesn't match the policy. Connection refused almost always comes from the server

You can use to automate this, you could define the foreign key constraint with ON DELETE CASCADE.
I quote the the manual of foreign key constraints:

CASCADE specifies that when a referenced row is deleted, row(s) referencing it should be automatically deleted as well.

TROUBLESHOOTING STEPS (Doc ID 730066.1)

Connection Timeout errors ORA-3135 and ORA-3136 A connection timeout error can be issued when an attempt to connect to the database does not complete its connection and authentication phases within the time period allowed by the following: SQLNET.INBOUND_CONNECT_TIMEOUT and/or INBOUND_CONNECT_TIMEOUT_ server-side parameters.

Starting with Oracle 10.2, the default for these parameters is 60 seconds where in previous releases it was 0, meaning no timeout.

On a timeout, the client program will receive the ORA-3135 (or possibly TNS-3135) error:

ORA-3135 connection lost contact

and the database will log the ORA-3136 error in its alert.log:

... Sat May 10 02:21:38 2008 WARNING: inbound connection timed out (ORA-3136) ...

• Authentication SQL

When a database session is in the authentication phase, it will issue a sequence of SQL statements. The authentication is not complete until all these are parsed, executed, fetched completely. Some of the SQL statements in this list e.g. on 10.2 are:

select value$ from props$ where name = 'GLOBAL_DB_NAME'

select privilege#,level from sysauth$ connect by grantee#=prior privilege# 
and privilege#>0 start with grantee#=:1 and privilege#>0

select SYS_CONTEXT('USERENV', 'SERVER_HOST'), SYS_CONTEXT('USERENV', 'DB_UNIQUE_NAME'),
SYS_CONTEXT('USERENV', 'INSTANCE_NAME'), SYS_CONTEXT('USERENV', 'SERVICE_NAME'), 
INSTANCE_NUMBER, STARTUP_TIME, SYS_CONTEXT('USERENV', 'DB_DOMAIN') 
from v$instance where INSTANCE_NAME=SYS_CONTEXT('USERENV', 'INSTANCE_NAME')

select privilege# from sysauth$ where (grantee#=:1 or grantee#=1) and privilege#>0

ALTER SESSION SET NLS_LANGUAGE= 'AMERICAN' NLS_TERRITORY= 'AMERICA' NLS_CURRENCY= '$'
NLS_ISO_CURRENCY= 'AMERICA' NLS_NUMERIC_CHARACTERS= '.,' NLS_CALENDAR= 'GREGORIAN'
NLS_DATE_FORMAT= 'DD-MON-RR' NLS_DATE_LANGUAGE= 'AMERICAN' NLS_SORT= 'BINARY' TIME_ZONE= '+02:00'
NLS_COMP= 'BINARY' NLS_DUAL_CURRENCY= '$' NLS_TIME_FORMAT= 'HH.MI.SSXFF AM' NLS_TIMESTAMP_FORMAT=
'DD-MON-RR HH.MI.SSXFF AM' NLS_TIME_TZ_FORMAT= 'HH.MI.SSXFF AM TZR' NLS_TIMESTAMP_TZ_FORMAT=
'DD-MON-RR HH.MI.SSXFF AM TZR'

NOTE: The list of SQL above is not complete and does not represent the ordering of the authentication SQL . Differences may also exist from release to release.

• Hangs during Authentication

The above SQL statements need to be Parsed, Executed and Fetched as happens for all SQL inside an Oracle Database. It follows that any problem encountered during these phases which appears as a hang or severe slow performance may result in a timeout.

Symptoms of such hangs will be seen by the authenticating session as waits for: • cursor: pin S wait on X • latch: row cache objects • row cache lock Other types of wait events are possible; this list may not be complete.

The issue here is that the authenticating session is blocked waiting to get a shared resource which is held by another session inside the database. That blocker session is itself occupied in a long-running activity (or its own hang) which prevents it from releasing the shared resource needed by the authenticating session in a timely fashion. This results in the timeout being eventually reported to the authenticating session.

• Troubleshooting of Authentication hangs

In such situations, we need to find out the blocker process holding the shared resource needed by the authenticating session in order to see what is happening to it.

Typical diagnostics used in such cases are the following:

1. Three consecutive systemstate dumps at level 266 during the time that one or more authenticating sessions are blocked. It is likely that the blocking session will have caused timeouts to more than one connection attempt. Hence, systemstate dumps can be useful even when the time needed to generate them exceeds the period of a single timeout e.g. 60 sec:

      $ sqlplus -prelim '/ as sysdba' 

       oradebug setmypid 
       oradebug unlimit 
       oradebug dump systemstate 266 
       ...wait 90 seconds 
       oradebug dump systemstate 266 
       ...wait 90 seconds 
       oradebug dump systemstate 266 
       quit

• ASH reports covering e.g. 10-15 minutes of a time period during which several timeout errors were seen.
• If possible, Two consecutive queries on V$LATCHHOLDER view for the case where the shared resource being waited for is a latch. select * from v$latchholder; The systemstate dumps should help in identifying the blocker session. Level 266 will show us in what code it is executing which may help in locating any existing bug as the root cause.

Examples of issues which can result in Authentication hangs

• Unpublished Bug 6879763 shared pool simulator bug fixed by patch for unpublished Bug 6966286 see Note 563149.1

• Unpublished Bug 7039896 workaround parameter _enable_shared_pool_durations=false see Note 7039896.8

• Other approaches to avoid the problem

In some cases, it may be possible to avoid problems with Authentication SQL by pinning such statements in the Shared Pool soon after the instance is started and they are freshly loaded. You can use the following artcile to advise on this: Document 726780.1 How to Pin a Cursor in the Shared Pool using DBMS_SHARED_POOL.KEEP

Pinning will prevent them from being flushed out due to inactivity and aging and will therefore prevent them for needing to be reloaded in the future i.e. needing to be reparsed and becoming susceptible to Authentication hang issues.

What caused this error in my case was having two @GET methods with the same path in a single resource. Changing the @Path of one of the methods solved it for me.

I ran into this problem as well, it ended up that I had two postgres servers running at the same time. I uninstalled one of them and changed the port back to 5432 and works fine now.

Use $.fn.add to concatenate two sets.

Fancy way to put @rdhs answer in a function:

Function arrayZero(size As Integer)
  arrayZero = Evaluate("=IF(ISERROR(Transpose(A1:A" & size & ")), 0, 0)")
End Function

And use like this:

myArray = arrayZero(15)

alter system set timed_statistics=true

--or

alter session set timed_statistics=true --if want to trace your own session

-- must be big enough:

select value from v$parameter p
where name='max_dump_file_size' 

-- Find out sid and serial# of session you interested in:

 select sid, serial# from v$session
 where ...your_search_params...

--you can begin tracing with 10046 event, the fourth parameter sets the trace level(12 is the biggest):

 begin
    sys.dbms_system.set_ev(sid, serial#, 10046, 12, '');
 end;

--turn off tracing with setting zero level:

begin
   sys.dbms_system.set_ev(sid, serial#, 10046, 0, '');
end;

/*possible levels: 0 - turned off 1 - minimal level. Much like set sql_trace=true 4 - bind variables values are added to trace file 8 - waits are added 12 - both bind variable values and wait events are added */

--same if you want to trace your own session with bigger level:

alter session set events '10046 trace name context forever, level 12';

--turn off:

alter session set events '10046 trace name context off';

--file with raw trace information will be located:

 select value from v$parameter p
 where name='user_dump_dest'

--name of the file(*.trc) will contain spid:

 select p.spid from v$session s, v$process p
 where s.paddr=p.addr
 and ...your_search_params...

--also you can set the name by yourself:

alter session set tracefile_identifier='UniqueString';

Just kind of translated http://www.sql.ru/faq/faq_topic.aspx?fid=389 Original is fuller, but anyway this is better than what others posted IMHO

The official RFC which defines this specification could be found here:

git remote add coworker git://path/to/coworkers/repo.git
git fetch coworker
git checkout --track coworker/foo

This will setup a local branch foo, tracking the remote branch coworker/foo. So when your co-worker has made some changes, you can easily pull them:

git checkout foo
git pull

Response to comments:

Cool :) And if I'd like to make my own changes to that branch, should I create a second local branch "bar" from "foo" and work there instead of directly on my "foo"?

You don't need to create a new branch, even though I recommend it. You might as well commit directly to foo and have your co-worker pull your branch. But that branch already exists and your branch foo need to be setup as an upstream branch to it:

git branch --set-upstream foo colin/foo

assuming colin is your repository (a remote to your co-workers repository) defined in similar way:

git remote add colin git://path/to/colins/repo.git

1. Run Android Studio.
2. From the menu bar, select Android Studio
3. Under IDE Settings, click Plugins and then select Search Subversion Integration
4. Check SubVersion.
5. Restart Android Studio.

Barring the CSS solution. The fastest possible way is to hide it immediatly with a script.

<div id="hideme"></div>
<script type="text/javascript">
    $("#hideme").hide();
</script>

In this case I would recommend the CSS solution by Vega. But if you need something more complex (like an animation) you can use this approach.

This has some complications (see comments below). If you want this piece of script to really run as fast as possible you can't use jQuery, use native JS only and defer loading of all other scripts.

I had an "Invalid Name"

I switched from "name": "Some Name",... to "name": "Some-Name",...

Guess name needs to be a sluggy string.

If you know the some content of the file you can try to decode it with several encoding and see which is missing. In general there is no way since a text file is a text file and those are stupid ;)

Our codebase is about 2.2MLoC for about 150 man-years effort. That makes it about 75 lines of c++ or c# per developer per day, over the whole life of the project.

It is possible to use a handler to do this, even in MVC4. Here's an example from one i made earlier:

public class ImageHandler : IHttpHandler
{
    byte[] bytes;

    public void ProcessRequest(HttpContext context)
    {
        int param;
        if (int.TryParse(context.Request.QueryString["id"], out param))
        {
            using (var db = new MusicLibContext())
            {
                if (param == -1)
                {
                    bytes = File.ReadAllBytes(HttpContext.Current.Server.MapPath("~/Images/add.png"));

                    context.Response.ContentType = "image/png";
                }
                else
                {
                    var data = (from x in db.Images
                                where x.ImageID == (short)param
                                select x).FirstOrDefault();

                    bytes = data.ImageData;

                    context.Response.ContentType = "image/" + data.ImageFileType;
                }

                context.Response.Cache.SetCacheability(HttpCacheability.NoCache);
                context.Response.BinaryWrite(bytes);
                context.Response.Flush();
                context.Response.End();
            }
        }
        else
        {
            //image not found
        }
    }

    public bool IsReusable
    {
        get
        {
            return false;
        }
    }
}

In the view, i added the ID of the photo to the query string of the handler.

An example, available for POSIX compliant systems :

/*
 * This program displays the names of all files in the current directory.
 */

#include <dirent.h> 
#include <stdio.h> 

int main(void) {
  DIR *d;
  struct dirent *dir;
  d = opendir(".");
  if (d) {
    while ((dir = readdir(d)) != NULL) {
      printf("%s\n", dir->d_name);
    }
    closedir(d);
  }
  return(0);
}

Beware that such an operation is platform dependant in C.

You can also use unlist(), which is often useful for handling lists:

> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))

> mylist
$A
[1] 1 2 3

$B
[1] 4 5 6

$C
[1] 7 8 9

> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3 
 1  2  3  4  5  6  7  8  9 

> length(unlist(mylist))
[1] 9

unlist() is a simple way of executing other functions on lists as well, such as:

> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument

> sum(unlist(mylist))
[1] 45

If

(1) you have a _Layout.cshtml view like this

<html>
    <body>
        @RenderBody()

    </body>
    <script type="text/javascript" src="~/lib/layout.js"></script>
    @RenderSection("scripts", required: false)
</html>

(2) you have Contacts.cshtml

@section Scripts{
    <script type="text/javascript" src="~/lib/contacts.js"></script>

}
<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <h2>    Contacts</h2>
    </div>
</div>

(3) you have About.cshtml

<div class="row">
    <div class="col-md-6 col-md-offset-3">
        <h2>    Contacts</h2>
    </div>
</div>

On you layout page, if required is set to false "@RenderSection("scripts", required: false)", When page renders and user is on about page, the contacts.js doesn't render.

    <html>
        <body><div>About<div>             
        </body>
        <script type="text/javascript" src="~/lib/layout.js"></script>
    </html>

if required is set to true "@RenderSection("scripts", required: true)", When page renders and user is on ABOUT page, the contacts.js STILL gets rendered.

<html>
    <body><div>About<div>             
    </body>
    <script type="text/javascript" src="~/lib/layout.js"></script>
    <script type="text/javascript" src="~/lib/contacts.js"></script>
</html>

IN SHORT, when set to true, whether you need it or not on other pages, it will get rendered anyhow. If set to false, it will render only when the child page is rendered.

I don't yet have the rep needed to add a comment or I would have just added this to Bell's answer. I think Bell did a very good job of summing up the top level pros and cons of the two approaches. Just a few other factors that you might want to consider:

1) Do the requests between your clients and your service need to go through intermediaries that require access to the payload? If so then WS-Security might be a better fit.

2) It is actually possible to use SSL to provide the server with assurance as to the clients identity using a feature called mutual authentication. However, this doesn't get much use outside of some very specialized scenarios due to the complexity of configuring it. So Bell is right that WS-Sec is a much better fit here.

3) SSL in general can be a bit of a bear to setup and maintain (even in the simpler configuration) due largely to certificate management issues. Having someone who knows how to do this for your platform will be a big plus.

4) If you might need to do some form of credential mapping or identity federation then WS-Sec might be worth the overhead. Not that you can't do this with REST, you just have less structure to help you.

5) Getting all the WS-Security goop into the right places on the client side of things can be more of a pain than you would think it should.

In the end though it really does depend on a lot of things we're not likely to know. For most situations I would say that either approach will be "secure enough" and so that shouldn't be the main deciding factor.

You should return only one column and one row in the where query where you assign the returned value to a variable. Example:

select * from table1 where Date in (select * from Dates) -- Wrong
select * from table1 where Date in (select Column1,Column2 from Dates) -- Wrong
select * from table1 where Date in (select Column1 from Dates) -- OK

I came here because I was trying to do the same thing; I knew I had dupes in the source data but only wanted to update the target data and not add the dupes.

I think a MERGE works great here because you can UPDATE or DELETE things that are different and INSERT things that are missing.

I ended up doing this and it worked great. I use SSIS to loop through Excel files and load them into a "RAW" SQL table with dupes and all. Then I run a MERGE to merge the "raw" table with the production table. Then I TRUNCATE the "raw" table and move to the next Excel file.

if you want both out and err streams redirected

dir >> a.txt 2>&1

./ refers to the current working directory, except in the require() function. When using require(), it translates ./ to the directory of the current file called. __dirname is always the directory of the current file.

For example, with the following file structure

/home/user/dir/files/config.json

{
  "hello": "world"
}

/home/user/dir/files/somefile.txt

text file

/home/user/dir/dir.js

var fs = require('fs');

console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));

If I cd into /home/user/dir and run node dir.js I will get

{ hello: 'world' }
text file

But when I run the same script from /home/user/ I get

{ hello: 'world' }

Error: ENOENT, no such file or directory './files/somefile.txt'
    at Object.openSync (fs.js:228:18)
    at Object.readFileSync (fs.js:119:15)
    at Object.<anonymous> (/home/user/dir/dir.js:4:16)
    at Module._compile (module.js:432:26)
    at Object..js (module.js:450:10)
    at Module.load (module.js:351:31)
    at Function._load (module.js:310:12)
    at Array.0 (module.js:470:10)
    at EventEmitter._tickCallback (node.js:192:40)

Using ./ worked with require but not for fs.readFileSync. That's because for fs.readFileSync, ./ translates into the cwd (in this case /home/user/). And /home/user/files/somefile.txt does not exist.

If you know all your 21 characters in advance you can write them all as one String and then check it like this:

char wanted = 'x';
String candidates = "abcdefghij...";
boolean hit = candidates.indexOf(wanted) >= 0;

I think this is the shortest way.

As pointed out by Max, you can't, but checking files modified or accessed is not all that hard. I wrote a tutorial about this, as late as today. The essence of which is to use -newerXY and ! -newerXY:

Example: To find all files modified on the 7th of June, 2007:

$ find . -type f -newermt 2007-06-07 ! -newermt 2007-06-08

To find all files accessed on the 29th of september, 2008:

$ find . -type f -newerat 2008-09-29 ! -newerat 2008-09-30

Or, files which had their permission changed on the same day:

$ find . -type f -newerct 2008-09-29 ! -newerct 2008-09-30

If you don't change permissions on the file, 'c' would normally correspond to the creation date, though.

How about FK_TABLENAME_COLUMNNAME?

Keep It Simple Stupid whenever possible.

You could try this:

SELECT * INTO tbl_NewTableName 
FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Then run a simple delete:

DELETE FROM tbl_OldTableName
WHERE Condition1=@Condition1Value

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

Based on Tomasz Nurkiewiczs answer, the "problem" is that typescript is typesafe. :) So the document.getElementById() returns the type HTMLElement which does not contain a value property. The subtype HTMLInputElement does however contain the value property.

So a solution is to cast the result of getElementById() to HTMLInputElement like this:

var inputValue = (<HTMLInputElement>document.getElementById(elementId)).value;

<> is the casting operator in typescript. See the question TypeScript: casting HTMLElement.

The resulting javascript from the line above looks like this:

inputValue = (document.getElementById(elementId)).value;

i.e. containing no type information.

Like nearly everyone else said, go to file -> Import Settings.

But if you don't see the "Import Settings" option under the file menu, you need to disable 2 plugins : IDE Settings Sync and Settings Repository

Here are two approaches. You may want to add handling for when the array is empty.

public static void FindMax()
{
    // Advantages: 
    // * Functional approach
    // * Compact code
    // Cons: 
    // * We are indexing into the array twice at each step
    // * The Range and IEnumerable add a bit of overhead
    // * Many people will find this code harder to understand

    int[] array = { 1, 5, 2, 7 };

    int maxIndex = Enumerable.Range(0, array.Length).Aggregate((max, i) => array[max] > array[i] ? max : i);
    int maxInt = array[maxIndex];

    Console.WriteLine($"Maximum int {maxInt} is found at index {maxIndex}");
}

public static void FindMax2()
{
    // Advantages: 
    // * Near-optimal performance

    int[] array = { 1, 5, 2, 7 };
    int maxIndex = -1;
    int maxInt = Int32.MinValue;

    // Modern C# compilers optimize the case where we put array.Length in the condition
    for (int i = 0; i < array.Length; i++)
    {
        int value = array[i];
        if (value > maxInt)
        {
            maxInt = value;
            maxIndex = i;
        }
    }

    Console.WriteLine($"Maximum int {maxInt} is found at index {maxIndex}");
}

There are method join for string objects:

".".join(("a","b","c"))

Add inside your input tag: onkeyup="value=value.replace(/[^\d]/g,'')"

You can upload up to 8 screenshots. Those screenshots must be one of the dimensions (sizes) you listed; you can have multiple screenshots of the same dimensions.

You can create a temporary parent node, and get the innerHTML content of it:

var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));

var tmp = document.createElement("div");
tmp.appendChild(el);
console.log(tmp.innerHTML); // <p>Test</p>

EDIT: Please see answer below about outerHTML. el.outerHTML should be all that is needed.

thanks for the ideas but none works here. So i did that... I am using xampp last version on 2014. go to \xampp\apache\conf\extra\httpd-xampp.conf.

we will find this bit of code:

<IfModule php5_module>
    **<FilesMatch "\.php$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

Focus on second line, so we must to change to:

<IfModule php5_module>
    **<FilesMatch "\.(php|html)$">**
        SetHandler application/x-httpd-php
    </FilesMatch>
    <FilesMatch "\.phps$">
        SetHandler application/x-httpd-php-source
    </FilesMatch>

    PHPINIDir "C:/xampp/php"
</IfModule>

And that is it. Works good!

You can index Dictionary, you didn't need 'get'.

Dictionary<string,string> example = new Dictionary<string,string>();
...
example.Add("hello","world");
...
Console.Writeline(example["hello"]);

An efficient way to test/get values is TryGetValue (thanx to Earwicker):

if (otherExample.TryGetValue("key", out value))
{
    otherExample["key"] = value + 1;
}

With this method you can fast and exception-less get values (if present).

String.Trim() returns a string which equals the input string with all white-spaces trimmed from start and end:

"   A String   ".Trim() -> "A String"

String.TrimStart() returns a string with white-spaces trimmed from the start:

"   A String   ".TrimStart() -> "A String   "

String.TrimEnd() returns a string with white-spaces trimmed from the end:

"   A String   ".TrimEnd() -> "   A String"

None of the methods modify the original string object.

(In some implementations at least, if there are no white-spaces to be trimmed, you get back the same string object you started with:

csharp> string a = "a"; csharp> string trimmed = a.Trim(); csharp> (object) a == (object) trimmed; returns true

I don't know whether this is guaranteed by the language.)

Add following gems in your gem file

gem 'therubyracer'
gem 'execjs'

and run

bundle install

you are done :)

Try this. Just add an empty option. This will solve your problem.

<select onchange="jsFunction()">
    <option></option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
</select>?

I observed that for all the answers provided here, the things are not working if we select some portion of the text in textbox and try to overwrite that part. So I modified the function which is as below:

    <HTML>
  <HEAD>
    <SCRIPT language=Javascript>
       <!--
       function isNumberKey(evt)
       {
         var charCode = (evt.which) ? evt.which : event.keyCode;

if (charCode != 46 && charCode > 31 && (charCode < 48 || charCode > 57))
{
        return false;
}
 if (charCode == 46 && evt.srcElement.value.split('.').length>1 )
    {

        return false;

    } 

 if(evt.srcElement.selectionStart<evt.srcElement.selectionEnd)
    {
          return true;
    }

  if(evt.srcElement.value.split('.').length>1 && evt.srcElement.value.split('.')[1].length==2)
  {

     return false;
  }


    return true;
       }


       //-->
    </SCRIPT>
  </HEAD>
  <BODY>
    <INPUT id="txtChar" onkeypress="return isNumberKey(event)" 
           type="text" name="txtChar">
  </BODY>
</HTML>

The fix is really simple: just replace YOUR_API_KEY on the last line of your code with your actual API key!

If you don't have one, you can get it for free on the Google Developers Website.

Remove single quotes around @username, and with respect to oracle use : with parameter name instead of @, like:

OracleCommand oraCommand = new OracleCommand("SELECT fullname FROM sup_sys.user_profile
                           WHERE domain_user_name = :userName", db);
oraCommand.Parameters.Add(new OracleParameter("userName", domainUser));

1) Backup your htdocs folder
2) export your databases (follow this tutorial)
3) uninstall xampp
4) install the new version of xampp
5) replace the htdocs folder that you have backed up
6) Import your databases you had exported before

Note: In case you have changed config files like PHP (php.ini), Apache (httpd.conf) or any other, please take back up of those files as well and replace them with newly installed version.

In addition to the answer of BalusC, use the following Java RegExp to replace && with and:

Search:  (#\{[^\}]*)(&&)([^\}]*\})
Replace: $1and$3

You have run this regular expression replacement multiple times to find all occurences in case you are using >2 literals in your EL expressions. Mind to replace the leading # by $ if your EL expression syntax differs.

There are different solutions to this problem . One of these , i will show you on my experiment and outcomes seen on results using a recent android studio and AVD images downloaded 2017.

1. First thing you have to do is launch your AVD from android studio.(in my case i choose NEXUSAPI25 android 7.1 image)

2. Goto Settings->Wirless and Networking - > Cellular Network - > Access Points -> (+) press add - > enter the following if you dont have NTLM proxy or proxy at all (that means you are directly connected)

   a. add apn name as myAPN b. add apn server => www c. save and try browsing the internet.

if this doesn work add 'ANDROID_SDK_ROOT' in you environment variable

Then , launch AVD using emulator command as follow

emulator -avd Nexus25 -dns-server 8.8.8.8

3. For those who use NTLM proxies , i will show you how it work for me next.

4. add your Android_sdk_root path into your environment variable. THis make command line code read succesfully like using AVD names and so on.

5. Launch your emaulator using the following command

>emulator -avd Nexus_5X_API_25 -http-proxy http://username:password@ipaddress:port

ENTER

Schnapple asks:

Are you referring to the concept of a free database to distribute with an application, or an Access-like "single file, no installation" database?

Er, nobody who has any competence with Access application development would ever distribute a single MDB/ACCDB as application/data store. Any non-trivial Access application needs to be split into a front end with the forms/queries/reports (i.e., UI objects) and a back end (data tables only).

It's clear that what is needed here is a database application development tool like Access. None of the database-only answers are in any way responsive to that.

Please learn about Access before answering Access questions:

• Access is a database application development tool that ships with a default database engine called Jet.

• But an Access application can be built to work with data in almost any back end database, as long as there's an ISAM, or an ODBC or OLEDB driver for that database engine.

Microsoft itself has done a good job of obfuscating the difference between Access (development tool) and Jet (database engine), so it's not surprising that many people don't recognize the difference. But developers ought to use precise language, and when you mean the database engine, use "Jet", and when you mean the front-end development platform, use "Access".

Multi-line buttons like that are not really trivial to implement. This page has an interesting (though somewhat dated) discussion on the subject. Your best bet would probably be to either drop the multi-line requirement or to create a custom button using e.g. divs and CSS, and adding some JavaScript to make it work as a button.

This article helped me alot figuring out why it wasn't working for me either. It give me a lesson to think of the webpage loading and how angular 2 interacts as a timeline and not just the point in time i'm thinking of. I didn't see anyone else mention this point, so I will...

The reason the *ngIf is needed because it will try to check the length of that variable before the rest of the OnInit stuff happens, and throw the "length undefined" error. So thats why you add the ? because it won't exist yet, but it will soon.

What about using TryParse?

You can use boost lexical cast:

#include <boost/lexical_cast.hpp>

string v("0.6");
double dd = boost::lexical_cast<double>(v);
cout << dd << endl;

Note: boost::lexical_cast throws exception so you should be prepared to deal with it when you pass invalid value, try passing string("xxx")

I have recently been wrestling with this. My issue was the solutions posted above using the heightForRowAtIndexPath: method would work for iOS 7.1 in the Simulator but then have completely screwed up results by simply switching to iOS 8.1.

I began reading more about self-sizing cells (introduced in iOS 8, read here). It was apparent that the use of UITableViewAutomaticDimension would help in iOS 8. I tried using that technique and deleted the use of heightForRowAtIndexPath: and voila, it was working perfect in iOS 8 now. But then iOS 7 wasn't. What was I to do? I needed heightForRowAtIndexPath: for iOS 7 and not for iOS 8.

Here is my solution (trimmed up for brevity's sake) which borrow's from the answer @JosephH posted above:

- (void)viewDidLoad {
    [super viewDidLoad];

    self.tableView.estimatedRowHeight = 50.;
    self.tableView.rowHeight = UITableViewAutomaticDimension;

    // ...
}

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0")) {
        return UITableViewAutomaticDimension;

    } else {
        NSString *cellIdentifier = [self reuseIdentifierForCellAtIndexPath:indexPath];
        static NSMutableDictionary *heightCache;
        if (!heightCache)
            heightCache = [[NSMutableDictionary alloc] init];
        NSNumber *cachedHeight = heightCache[cellIdentifier];
        if (cachedHeight)
            return cachedHeight.floatValue;

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
    CGFloat height = cell.bounds.size.height;
    heightCache[cellIdentifier] = @(height);
    return height;
    }
}

- (NSString *)reuseIdentifierForCellAtIndexPath:(NSIndexPath *)indexPath {
    NSString * reuseIdentifier;
    switch (indexPath.row) {
        case 0:
            reuseIdentifier = EventTitleCellIdentifier;
            break;
        case 2:
            reuseIdentifier = EventDateTimeCellIdentifier;
            break;
        case 4:
            reuseIdentifier = EventContactsCellIdentifier;
            break;
        case 6:
            reuseIdentifier = EventLocationCellIdentifier;
            break;
        case 8:
            reuseIdentifier = NotesCellIdentifier;
            break;
        default:
            reuseIdentifier = SeparatorCellIdentifier;
            break;
    }

    return reuseIdentifier;
}

SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0") is actually from a set of macro definitions I am using which I found somewhere (very helpful). They are defined as:

#define SYSTEM_VERSION_EQUAL_TO(v)                  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedSame)
#define SYSTEM_VERSION_GREATER_THAN(v)              ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedDescending)
#define SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN(v)                 ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)
#define SYSTEM_VERSION_LESS_THAN_OR_EQUAL_TO(v)     ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedDescending)

  works but that is not right way I think the w min-height: 1px;

i it integer, int to Integer

Integer intObj = new Integer(i);

From the fine manual:

ALTER TABLE mytable ALTER COLUMN mycolumn DROP NOT NULL;

There's no need to specify the type when you're just changing the nullability.

Pressing enter in a form's text field will, by default, submit the form. If you don't want it to work that way you have to capture the enter key press and consume it like you've done. There is no way around this. It will work this way even if there is no button present in the form.

Intro

I also encountered this problem and the solution proposed by @adamo was basically the right solution. However, I had to invest a lot of time in the details, which is why I am now writing a new answer in order to save this time for others.

Case

My case was as follows: There was a table that was filled with data using an app. Now a new entry had to be inserted manually via SQL. After that the sequence was out of sync and no more records could be inserted via the app.

Solution

As mentioned in the answer from @adamo, the sequence must be synchronized manually. For this purpose the name of the sequence is needed. For Postgres, the name of the sequence can be determined with the command PG_GET_SERIAL_SEQUENCE. Most examples use lower case table names. In my case the tables were created by an ORM middleware (like Hibernate or Entity Framework Core etc.) and their names all started with a capital letter.

In an e-mail from 2004 (link) I got the right hint.

(Let's assume for all examples, that Foo is the table's name and Foo_id the related column.)

Command to get the sequence name:

SELECT PG_GET_SERIAL_SEQUENCE('"Foo"', 'Foo_id');

So, the table name must be in double quotes, surrounded by single quotes.

1. Validate, that the sequence is out-of-sync

SELECT CURRVAL(PG_GET_SERIAL_SEQUENCE('"Foo"', 'Foo_id')) AS "Current Value", MAX("Foo_id") AS "Max Value" FROM "Foo";

When the Current Value is less than Max Value, your sequence is out-of-sync.

2. Correction

SELECT SETVAL((SELECT PG_GET_SERIAL_SEQUENCE('"Foo"', 'Foo_id')), (SELECT (MAX("Foo_id") + 1) FROM "Foo"), FALSE);

Page content can be displayed easily and perfectly this way:

<?php if(have_posts()) : ?>
    <?php while(have_posts())  : the_post(); ?>
      <h2><?php the_title(); ?></h2>                        
      <?php the_content(); ?>          
      <?php comments_template( '', true ); ?> 
    <?php endwhile; ?>                   
      <?php else : ?>                       
        <h3><?php _e('404 Error&#58; Not Found'); ?></h3>
<?php endif; ?>         

Note:

In terms of displaying content - i) comments_template() function is an optional use if you need to enable commenting with different functionality.

ii) _e() function is also optional but more meaningful & effective than just showing text through <p>. while preferred stylized 404.php can be created to be redirected.

It's simpler if you modify your HTML a little bit:

<label for="first_name">First Name</label>
<input type="text" id="name" name="name" />

<label for="surname">Surname</label>
<input type="text" id="surname" name="surname" />

<label for="firstname">Firstname</label>
<input type="text" id="firstname" name="firstname" disabled="disabled" />

then it's relatively simple

$(document).ready(function() { 
    $('#name').change(function() {
      $('#firstname').val($('#name').val());
    });
});

Gulp uses micromatch under the hood for matching globs, so if you want to exclude any of the .min.js files, you can achieve the same by using an extended globbing feature like this:

src("'js/**/!(*.min).js")

Basically what it says is: grab everything at any level inside of js that doesn't end with *.min.js

I know this has been a while.. but here is an idea

declare @test varchar(25) = 'images/test.jpg'

select
 @test as column_name
 , parsename(replace(@test,'/','.'),1) as jpg
 ,parsename(replace(@test,'/','.'),2) as test
  ,parsename(replace(@test,'/','.'),3) as images

{ "scripts" :
  { "build": "node build.js"}
}

npm run build OR npm run-script build

{
  "name": "build",
  "version": "1.0.0",
  "scripts": {
    "start": "node build.js"
  }
}

npm start

NB: you were missing the { brackets } and the node command

folder structure is fine:

+ build
  - package.json
  - build.js

For those experimenting with this in phpMyAdmin, just a word:

phpMyAdmin appears to have a few problems with USING. For the record this is phpMyAdmin run on Linux Mint, version: "4.5.4.1deb2ubuntu2", Database server: "10.2.14-MariaDB-10.2.14+maria~xenial - mariadb.org binary distribution".

I have run SELECT commands using JOIN and USING in both phpMyAdmin and in Terminal (command line), and the ones in phpMyAdmin produce some baffling responses:

1) a LIMIT clause at the end appears to be ignored.
2) the supposed number of rows as reported at the top of the page with the results is sometimes wrong: for example 4 are returned, but at the top it says "Showing rows 0 - 24 (2503 total, Query took 0.0018 seconds.)"

Logging on to mysql normally and running the same queries does not produce these errors. Nor do these errors occur when running the same query in phpMyAdmin using JOIN ... ON .... Presumably a phpMyAdmin bug.

I modified some thing that were poping up error for me and end up with this which worked great to extract the data as I needed:

Sub get_data_web()

Dim appIE As Object
Set appIE = CreateObject("internetexplorer.application")

With appIE
    .navigate "https://finance.yahoo.com/quote/NQ%3DF/futures?p=NQ%3DF"
    .Visible = True
End With

Do While appIE.Busy
    DoEvents
Loop

Set allRowofData = appIE.document.getElementsByClassName("Ta(end) BdT Bdc($c-fuji-grey-c) H(36px)")

Dim i As Long
Dim myValue As String

Count = 1

    For Each itm In allRowofData

        For i = 0 To 4

        myValue = itm.Cells(i).innerText
        ActiveSheet.Cells(Count, i + 1).Value = myValue

        Next

        Count = Count + 1

    Next

appIE.Quit
Set appIE = Nothing


End Sub

here is simple code

List <String> list = new ArrayList <String>();
list.add("a");
list.add("b");
JSONArray array = new JSONArray();
for (int i = 0; i < list.size(); i++) {
        array.put(list.get(i));
}
JSONObject obj = new JSONObject();
try {
    obj.put("result", array);
} catch (JSONException e) {
 // TODO Auto-generated catch block
e.printStackTrace();
}
pw.write(obj.toString());

I got a very similar error message that was caused by inadvertently having made a duplicate of a class in another project of my solution. Deleting the duplicate fixed the issue

read from assets html file

ViewGroup webGroup;
  String content = readContent("content/ganji.html");

        final WebView webView = new WebView(this);
        webView.loadDataWithBaseURL(null, content, "text/html", "UTF-8", null);

        webGroup.addView(webView);

Set the activity content from a layout resource. ie.,setContentView(R.layout.basicXml);

element = findElement(By.xpath("//*[@test-id='test-username']");
element = findElement(By.xpath("//input[@test-id='test-username']");

(*) - any tagname

Replace this line:

$(this).target = "_blank";

With:

$( this ).attr( 'target', '_blank' );

That will set its HREF to _blank.

You can use this:

var isEmpty = function(obj) {
  return Object.keys(obj).length === 0;
}

or this:

function isEmpty(obj) {
  return !Object.keys(obj).length > 0;
}

You can also use this:

function isEmpty(obj) {
  for(var prop in obj) {
    if(obj.hasOwnProperty(prop))
      return false;
  }

  return true;
}

If using underscore or jQuery, you can use their isEmpty or isEmptyObject calls.

I had the same issue, and did this to fix it:

1. In command prompt

   pip install Pillow ##
   

2. Ensure that you use

   from PIL import Image
   

I in Image has to be capital. That was the issue in my case.

I like to use such static methods:

$result = $purchases_repository->matching(
    Criteria::create()->where(
        Criteria::expr()->gt('prize', 200)
    )
);

Of course, you can push logic when it is 1 condition, but when you have more conditions it is better to divide it into fragments, configure and pass it to the method:

$expr = Criteria::expr();

$criteria = Criteria::create();
$criteria->where($expr->gt('prize', 200));
$criteria->orderBy(['prize' => Criteria::DESC]);

$result = $purchases_repository->matching($criteria);

Below code for black:-

<color name="black">#000000</color>

Now if i want to use opacity than you can use below code :-

 <color name="black">#99000000</color> 

and below for opacity code:-

Any algorithm implemented using recursion can also be implemented using iteration.

Why not to use recursion

1. It is usually slower due to the overhead of maintaining the stack.
2. It usually uses more memory for the stack.

Why to use recursion

1. Recursion adds clarity and (sometimes) reduces the time needed to write and debug code (but doesn't necessarily reduce space requirements or speed of execution).
2. Reduces time complexity.
3. Performs better in solving problems based on tree structures.

For example, the Tower of Hanoi problem is more easily solved using recursion as opposed to iteration.

Add a label control to your Repeater's ItemTemplate. Handle OnItemCreated event.

ASPX

<asp:Repeater ID="rptr" runat="server" OnItemCreated="RepeaterItemCreated">
    <ItemTemplate>
        <div id="width:50%;height:30px;background:#0f0a0f;">
            <asp:Label ID="lblSr" runat="server" 
               style="width:30%;float:left;text-align:right;text-indent:-2px;" />
            <span 
               style="width:65%;float:right;text-align:left;text-indent:-2px;" >
            <%# Eval("Item") %>
            </span>
        </div>
    </ItemTemplate>
</asp:Repeater>

Code Behind:

    protected void RepeaterItemCreated(object sender, RepeaterItemEventArgs e)
    {
        Label l = e.Item.FindControl("lblSr") as Label;
        if (l != null)
            l.Text = e.Item.ItemIndex + 1+"";
    }

I know this is old, but I have to add this in here..

And while this is not a full answer, it is an 'IN ADDITION TO'

The address bar will not disappear if you're NOT using https.

ALSO

If you are using https and the address bar still won't hide, you might have some https errors in your webpage (such as certain images being served from a non-https location.)

Hope this helps..

A lot of this has to do with polymorphism. When you assign

X = new Y();

X can be much less 'specific' than Y, but not the other way around. X is just the handle you are accessing Y with, Y is the real instantiated thing,

You get an error here because Integer is a Number, but Number is not an Integer.

ArrayList<Integer> a = new ArrayList<Number>(); // compile-time error

As such, any method of X that you call must be valid for Y. Since X is more generally it probably shares some, but not all of Y's methods. Still, any arguments given must be valid for Y.

In your examples with add, an int (small i) is not a valid Object or Integer.

ArrayList<?> a = new ArrayList<?>();

This is no good because you can't actually instantiate an array list containing ?'s. You can declare one as such, and then damn near anything can follow in new ArrayList<Whatever>();

Josh David Miller is correct.

PCoelho, In case you're wondering what $compile does behind the scenes and how HTML output is generated from the directive, please take a look below

The $compile service compiles the fragment of HTML("< test text='n' >< / test >") that includes the directive("test" as an element) and produces a function. This function can then be executed with a scope to get the "HTML output from a directive".

var compileFunction = $compile("< test text='n' > < / test >");
var HtmlOutputFromDirective = compileFunction($scope);

I got that error because I was passing an incorrect parameter to the factory definition. I had:

myModule.factory('myService', function($scope, $http)...

It worked when I removed the $scope and changed the factory definition to:

myModule.factory('myService', function( $http)...

In case you need to inject $scope, use:

myModule.factory('myService', function($rootScope, $http)...

You can't solve it. Simply answer1.sum()==0, and you can't perform a division by zero.

This happens because answer1 is the exponential of 2 very large, negative numbers, so that the result is rounded to zero.

nan is returned in this case because of the division by zero.

Now to solve your problem you could:

• go for a library for high-precision mathematics, like mpmath. But that's less fun.
• as an alternative to a bigger weapon, do some math manipulation, as detailed below.
• go for a tailored scipy/numpy function that does exactly what you want! Check out @Warren Weckesser answer.

Here I explain how to do some math manipulation that helps on this problem. We have that for the numerator:

exp(-x)+exp(-y) = exp(log(exp(-x)+exp(-y)))
                = exp(log(exp(-x)*[1+exp(-y+x)]))
                = exp(log(exp(-x) + log(1+exp(-y+x)))
                = exp(-x + log(1+exp(-y+x)))

where above x=3* 1089 and y=3* 1093. Now, the argument of this exponential is

-x + log(1+exp(-y+x)) = -x + 6.1441934777474324e-06

For the denominator you could proceed similarly but obtain that log(1+exp(-z+k)) is already rounded to 0, so that the argument of the exponential function at the denominator is simply rounded to -z=-3000. You then have that your result is

exp(-x + log(1+exp(-y+x)))/exp(-z) = exp(-x+z+log(1+exp(-y+x)) 
                                   = exp(-266.99999385580668)

which is already extremely close to the result that you would get if you were to keep only the 2 leading terms (i.e. the first number 1089 in the numerator and the first number 1000 at the denominator):

exp(3*(1089-1000))=exp(-267)

For the sake of it, let's see how close we are from the solution of Wolfram alpha (link):

Log[(exp[-3*1089]+exp[-3*1093])/([exp[-3*1000]+exp[-3*4443])] -> -266.999993855806522267194565420933791813296828742310997510523

The difference between this number and the exponent above is +1.7053025658242404e-13, so the approximation we made at the denominator was fine.

The final result is

'exp(-266.99999385580668) = 1.1050349147204485e-116

From wolfram alpha is (link)

1.105034914720621496.. × 10^-116 # Wolfram alpha.

and again, it is safe to use numpy here too.

This can be done by using the unbind function.

$('#myimage').unbind('click');

You can add multiple event handlers to the same object and event in jquery. This means adding a new one doesn't replace the old ones.

There are several strategies for changing event handlers, such as event namespaces. There are some pages about this in the online docs.

Look at this question (that's how I learned of unbind). There is some useful description of these strategies in the answers.

For Mars (Eclipse 4.5) and WTP 3.7 use this link. http://download.eclipse.org/webtools/repository/mars/

1. In Eclipse select Help - Install New Software.
2. In the "Work with:" text box place the above link.
3. Press Enter.
4. Select the WTP version you need (3.7.0 or 3.7.1 as of today) & follow the prompts.

As you can see from the many answers, there are several solutions. One instance of LBYL (look before you leap) has not been mentioned yet, the has_key() method:

my_dict = {}

def add (key):
    if my_dict.has_key(key):
        my_dict[key] += 1
    else:
        my_dict[key] = 1

if __name__ == '__main__':
    add("foo")
    add("bar")
    add("foo")
    print my_dict

I'm using out of the box MVC4 with this code (note the two parameters inside ToDictionary)

 var result = new JsonResult()
 {
     Data = new
     {
         partials = GetPartials(data.Partials).ToDictionary(x => x.Key, y=> y.Value)
     }
 };

I get what's expected:

{"partials":{"cartSummary":"\u003cb\u003eCART SUMMARY\u003c/b\u003e"}}

Important: WebAPI in MVC4 uses JSON.NET serialization out of the box, but the standard web JsonResult action result doesn't. Therefore I recommend using a custom ActionResult to force JSON.NET serialization. You can also get nice formatting

Here's a simple actionresult JsonNetResult

You'll see the difference (and can make sure you're using the right one) when serializing a date:

Microsoft way:

 {"wireTime":"\/Date(1355627201572)\/"}

JSON.NET way:

 {"wireTime":"2012-12-15T19:07:03.5247384-08:00"}

You can use the JavaScript String concat() Method,

var str1 = "Hello ";
var str2 = "world!";
var res = str1.concat(str2); //will return "Hello world!"

Its syntax is:

string.concat(string1, string2, ..., stringX)

In Bootstrap 4 you have to use 'max-width' attribute and then it works perfectly.

<div id="modal_dialog" class="modal fade" tabindex="-1" role="dialog" style="display: none;">
<div class="modal-dialog" style="max-width: 1350px!important;" role="document">
    <div class="modal-content">
        <div class="modal-body">
            Sample text
        </div>
    </div>
</div>

With your main window, there will likely always be times with transitions that are incompatible with presenting an alert. In order to allow presenting alerts at any time in your application lifecycle, you should have a separate window to do the job.

Basic usage that, by design, will always succeed:

The proper way to remove a cookie is to set the max age to 0 and add the cookie back to the HttpServletResponse object.

Most people don't realize or forget to add the cookie back onto the response object. By doing that it will expire and remove the cookie immediately.

...retrieve cookie from HttpServletRequest
cookie.setMaxAge(0);
response.addCookie(cookie);

My Answer: All of the following should be overridden (i.e. describe them all within columndefinition, if appropriate):

• length
• precision
• scale
• nullable
• unique

i.e. the column DDL will consist of: name + columndefinition and nothing else.

Rationale follows.

1. Annotation containing the word "Column" or "Table" is purely physical - properties only used to control DDL/DML against database.

2. Other annotation purely logical - properties used in-memory in java to control JPA processing.

3. That's why sometimes it appears the optionality/nullability is set twice - once via @Basic(...,optional=true) and once via @Column(...,nullable=true). Former says attribute/association can be null in the JPA object model (in-memory), at flush time; latter says DB column can be null. Usually you'd want them set the same - but not always, depending on how the DB tables are setup and reused.

In your example, length and nullable properties are overridden and redundant.

So, when specifying columnDefinition, what other properties of @Column are made redundant?

1. In JPA Spec & javadoc:

   • columnDefinition definition: The SQL fragment that is used when generating the DDL for the column.

   • columnDefinition default: Generated SQL to create a column of the inferred type.

   • The following examples are provided:

     @Column(name="DESC", columnDefinition="CLOB NOT NULL", table="EMP_DETAIL")
     @Column(name="EMP_PIC", columnDefinition="BLOB NOT NULL")
     

   • And, err..., that's it really. :-$ ?!

   Does columnDefinition override other properties provided in the same annotation?

   The javadoc and JPA spec don't explicity address this - spec's not giving great protection. To be 100% sure, test with your chosen implementation.

2. The following can be safely implied from examples provided in the JPA spec

   • name & table can be used in conjunction with columnDefinition, neither are overridden
   • nullable is overridden/made redundant by columnDefinition

3. The following can be fairly safely implied from the "logic of the situation" (did I just say that?? :-P ):

   • length, precision, scale are overridden/made redundant by the columnDefinition - they are integral to the type
   • insertable and updateable are provided separately and never included in columnDefinition, because they control SQL generation in-memory, before it is emmitted to the database.

4. That leaves just the "unique" property. It's similar to nullable - extends/qualifies the type definition, so should be treated integral to type definition. i.e. should be overridden.

Test My Answer For columns "A" & "B", respectively:

  @Column(name="...", table="...", insertable=true, updateable=false,
          columndefinition="NUMBER(5,2) NOT NULL UNIQUE"

  @Column(name="...", table="...", insertable=false, updateable=true,
          columndefinition="NVARCHAR2(100) NULL"

• confirm generated table has correct type/nullability/uniqueness
• optionally, do JPA insert & update: former should include column A, latter column B

All this git reset, hard, soft, and everything else mentioned here is probably working (it didn't for me) if you do the steps correctly and some sort of a genie.
If you are the average Joe smo, try this:
How to use git merge --squash?

Saved my life, and will be my go to squash, been using this 4 times since I found out about it. Simple, clean and basically 1 comamnd. In short:


If you are on a branch lets call it "my_new_feature" off develop and your pull request has 35 commits (or however many) and you want it to be 1.

A. Make sure your branch is up to date, Go on develop, get latest and merge and resolve any conflicts with "my_new_feature"
(this step really you should take as soon as you can all the time anyway)

B. Get latest of develop and branch out to a new branch call it "my_new_feature_squashed"

C. magic is here.
You want to take your work from "my_new_feature" to "my_new_feature_squashed"
So just do (while on your new branch we created off develop):
git merge --squash my_new_feature

All your changes will now be on your new branch, feel free to test it, then just do your 1 single commit, push, new PR of that branch - and wait for repeat the next day.
Don't you love coding? :)

For those of you using AutoMapper If you are updating an entity that has foreign keys to another entity(or entities), make sure all of the foreign entities have their primary key set to database generated (or auto-incremented for MySQL).

For example:

public class BuyerEntity
{
    [Key]
    public int BuyerId{ get; set; }

    public int Cash { get; set; }

    public List<VehicleEntity> Vehicles { get; set; }

    public List<PropertyEntity> Properties { get; set; }

}

Vehicles and Properties are stored in other tables than Buyers. When you add a new buyer, AutoMapper and EF will automatically update the Vehicles and Properties tables so if you don't have auto-increment set up on either of those tables (like I didn't), then you will see the error from the OP's question.

You can create the same behavior creating a simple custom editor called DateTime.cshtml, saving it in Views/Shared/EditorTemplates

@model DateTime

@{
    var css = ViewData["class"] ?? "";
    @Html.TextBox("", (Model != DateTime.MinValue? Model.ToString("dd/MM/yyyy") : string.Empty), new { @class = "calendar medium " + css});
}

and in your views

@Html.EditorFor(model => model.StartDate, new { @class = "required" })

Note that in my example I'm hard-coding two css classes and the date format. You can, of course, change that. You also can do the same with others html attributes, like readonly, disabled, etc.

String temp = passwordSalt;
byte[] byteSalt = temp.getBytes();
int start = 32;
for (int i = 0; i < byteData.length; i ++)
{
    byteData[start + i] = byteSalt[i];
}

The problem with your code here is that the variable i that is being used to index the arrays is going past both the byteSalt array and the byteData array. So, Make sure that byteData is dimensioned to be at least the maximum length of the passwordSalt string plus 32. What will correct it is replacing the following line:

for (int i = 0; i < byteData.length; i ++)

with:

for (int i = 0; i < byteSalt.length; i ++)

Latest version of angular (7.2 +) now has the option to pass additional information using NavigationExtras.

Home component

import {
  Router,
  NavigationExtras
} from '@angular/router';
const navigationExtras: NavigationExtras = {
  state: {
    transd: 'TRANS001',
    workQueue: false,
    services: 10,
    code: '003'
  }
};
this.router.navigate(['newComponent'], navigationExtras);

newComponent

test: string;
constructor(private router: Router) {
  const navigation = this.router.getCurrentNavigation();
  const state = navigation.extras.state as {
    transId: string,
    workQueue: boolean,
    services: number,
    code: string
  };
  this.test = "Transaction Key:" + state.transId + "<br /> Configured:" + state.workQueue + "<br /> Services:" + state.services + "<br /> Code: " + state.code;
}

Output

Hope this would help!

I suggest

l = re.compile("(?<!^)\s+(?=[A-Z])(?!.\s)").split(s)

Check this demo.

Instead of catching the error, wouldn't it be possible to test in or before the myplotfunction() function first if the error will occur (i.e. if the breaks are unique) and only plot it for those cases where it won't appear?!

Ubuntu Users:

I had the same problem and I fixed it by installing nodejson my system independent of the gem.

on ubuntu its: sudo apt-get install nodejs

I'm using 64bit ubuntu 11.10

update: From @Galina 's answer below I'm guessing that the latest version of nodejs is required, so @steve98177 your best option on a redhat(or CentOS) box is to install from source code as @Galina did, but as you can't "make/install" on this box ?, I suggest you try to install a fedora rpm(long shot) https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager or find another RH/CentOs box(that you can 'make' on) and create your own rpm and install on original RH box(if old glibc on RH plays nice).

The real issue here(IMHO) is installing Gems that have dependencies on installed packages outside of the ruby environment, is there a way of knowing before installing ? an RFI for Gems or bundler ?

CentOS/RedHat Users:

sudo yum install nodejs

Any tensor returned by Session.run or eval is a NumPy array.

>>> print(type(tf.Session().run(tf.constant([1,2,3]))))
<class 'numpy.ndarray'>

Or:

>>> sess = tf.InteractiveSession()
>>> print(type(tf.constant([1,2,3]).eval()))
<class 'numpy.ndarray'>

Or, equivalently:

>>> sess = tf.Session()
>>> with sess.as_default():
>>>    print(type(tf.constant([1,2,3]).eval()))
<class 'numpy.ndarray'>

EDIT: Not any tensor returned by Session.run or eval() is a NumPy array. Sparse Tensors for example are returned as SparseTensorValue:

>>> print(type(tf.Session().run(tf.SparseTensor([[0, 0]],[1],[1,2]))))
<class 'tensorflow.python.framework.sparse_tensor.SparseTensorValue'>

You can simply use | filter:yourFunction:arg

<div ng-repeat="group in groups | filter:weDontLike:group">...</div>

And in js

$scope.weDontLike = function(group) {
//here your condition/criteria
return !!group 
}

If you control the remote server, you should probably use CORS, as described in this answer; it's supported in IE8 and up, and all recent versions of FF, GC, and Safari. (But in IE8 and 9, CORS won't allow you to send cookies in the request.)

So, if you don't control the remote server, or if you have to support IE7, or if you need cookies and you have to support IE8/9, you'll probably want to use an iframe technique.

1. Create an iframe with a unique name. (iframes use a global namespace for the entire browser, so pick a name that no other website will use.)
2. Construct a form with hidden inputs, targeting the iframe.
3. Submit the form.

Here's sample code; I tested it on IE6, IE7, IE8, IE9, FF4, GC11, S5.

function crossDomainPost() {
  // Add the iframe with a unique name
  var iframe = document.createElement("iframe");
  var uniqueString = "CHANGE_THIS_TO_SOME_UNIQUE_STRING";
  document.body.appendChild(iframe);
  iframe.style.display = "none";
  iframe.contentWindow.name = uniqueString;

  // construct a form with hidden inputs, targeting the iframe
  var form = document.createElement("form");
  form.target = uniqueString;
  form.action = "http://INSERT_YOUR_URL_HERE";
  form.method = "POST";

  // repeat for each parameter
  var input = document.createElement("input");
  input.type = "hidden";
  input.name = "INSERT_YOUR_PARAMETER_NAME_HERE";
  input.value = "INSERT_YOUR_PARAMETER_VALUE_HERE";
  form.appendChild(input);

  document.body.appendChild(form);
  form.submit();
}

Beware! You won't be able to directly read the response of the POST, since the iframe exists on a separate domain. Frames aren't allowed to communicate with each other from different domains; this is the same-origin policy.

If you control the remote server but you can't use CORS (e.g. because you're on IE8/IE9 and you need to use cookies), there are ways to work around the same-origin policy, for example by using window.postMessage and/or one of a number of libraries allowing you to send cross-domain cross-frame messages in older browsers:

• Porthole
• XSSInterface
• EasyXDM
• jQuery PostMessage Plugin

If you don't control the remote server, then you can't read the response of the POST, period. It would cause security problems otherwise.

Marquee (<marquee>) is a deprecated and not a valid HTML tag. You can use many jQuery plugins to do. One of it, is jQuery News Ticker. There are many more!

Because at least one value is a string the + operator is being interpreted as a string concatenation operator. The simplest fix for this is to indicate that you intend for the values to be interpreted as numbers.

var total = +a + +b;

and

$('#total_price').val(+a + +b);

Or, better, just pull them out as numbers to begin with:

var a = +$('input[name=service_price]').val();
var b = +$('input[name=modem_price]').val();
var total = a+b;
$('#total_price').val(a+b);

See Mozilla's Unary + documentation.

Note that this is only a good idea if you know the value is going to be a number anyway. If this is user input you must be more careful and probably want to use parseInt and other validation as other answers suggest.

Traceback (most recent call last):

>>>
>>> subprocess.call('echo $HOME', shell=True)

Setting the shell argument to a true value causes subprocess to spawn an intermediate shell process, and tell it to run the command. In other words, using an intermediate shell means that variables, glob patterns, and other special shell features in the command string are processed before the command is run. Here, in the example, $HOME was processed before the echo command. Actually, this is the case of command with shell expansion while the command ls -l considered as a simple command.

I think you cannot get it as String but you can get it as int by get resource id:

Swift 2, 3, 4, 5:

let elements = [1, 2, 3, 4, 5]
if elements.contains(5) {
    print("yes")
}

contains() is a protocol extension method of SequenceType (for sequences of Equatable elements) and not a global method as in earlier releases.

Remarks:

• This contains() method requires that the sequence elements adopt the Equatable protocol, compare e.g. Andrews's answer.
• If the sequence elements are instances of a NSObject subclass then you have to override isEqual:, see NSObject subclass in Swift: hash vs hashValue, isEqual vs ==.
• There is another – more general – contains() method which does not require the elements to be equatable and takes a predicate as an argument, see e.g. Shorthand to test if an object exists in an array for Swift?.

Swift older versions:

let elements = [1,2,3,4,5]
if contains(elements, 5) {
    println("yes")
}

An unmodifiable map may still change. It is only a view on a modifiable map, and changes in the backing map will be visible through the unmodifiable map. The unmodifiable map only prevents modifications for those who only have the reference to the unmodifiable view:

Map<String, String> realMap = new HashMap<String, String>();
realMap.put("A", "B");

Map<String, String> unmodifiableMap = Collections.unmodifiableMap(realMap);

// This is not possible: It would throw an 
// UnsupportedOperationException
//unmodifiableMap.put("C", "D");

// This is still possible:
realMap.put("E", "F");

// The change in the "realMap" is now also visible
// in the "unmodifiableMap". So the unmodifiableMap
// has changed after it has been created.
unmodifiableMap.get("E"); // Will return "F". 

In contrast to that, the ImmutableMap of Guava is really immutable: It is a true copy of a given map, and nobody may modify this ImmutableMap in any way.

Update:

As pointed out in a comment, an immutable map can also be created with the standard API using

Map<String, String> immutableMap = 
    Collections.unmodifiableMap(new LinkedHashMap<String, String>(realMap)); 

This will create an unmodifiable view on a true copy of the given map, and thus nicely emulates the characteristics of the ImmutableMap without having to add the dependency to Guava.

you could utilize bootstrap events:: as

//when modal opens
$('#yourModal').on('shown.bs.modal', function (e) {
  $("#pageContent").css({ opacity: 0.5 });
})

//when modal closes
$('#yourModal').on('hidden.bs.modal', function (e) {
  $("#pageContent").css({ opacity: 1 });
})

There's a good answer here:

function toTitleCase(str) {
    return str.replace(/\w\S*/g, function(txt){
        return txt.charAt(0).toUpperCase() + txt.substr(1).toLowerCase();
    });
}

or in ES6:

var text = "foo bar loo zoo moo";
text = text.toLowerCase()
    .split(' ')
    .map((s) => s.charAt(0).toUpperCase() + s.substring(1))
    .join(' ');

We have struggle a lot with this issue, and here's what works for us. If you use the conda-forge channel, it's important to make sure you are using updated packages from conda-forge, even in your Miniconda root environment.

So install Miniconda, and then do:

conda config --add channels conda-forge --force
conda update --all  -y
conda install nb_conda_kernels -y
conda env create -f custom_env.yml -q --force
jupyter notebook

and your custom environment will show up in Jupyter as an available kernel, as long as ipykernel was listed for installation in your custom_env.yml file, like this example:

name: bqplot
channels:
- conda-forge
- defaults
dependencies:
- python>=3.6
- bqplot
- ipykernel

Just to prove it working with a bunch of custom environments, here's a screen grab from Windows:

answers are already given but there's too much disinformation about performance. I wrote this little benchmark script that shows that the foreach method is the fastest.

Disclaimer: following methods were copy-pasted from the other answers

<?php

function method_1(Array &$arr) {
    return $arr === array_values($arr);
}

function method_2(Array &$arr) {
    for (reset($arr), $i = 0; key($arr) !== $i++; next($arr));
    return is_null(key($arr));
}

function method_3(Array &$arr) {
    return array_keys($arr) === range(0, count($arr) - 1);
}

function method_4(Array &$arr) {
    $idx = 0;
    foreach( $arr as $key => $val ){
        if( $key !== $idx )
            return FALSE;
        $idx++;
    }
    return TRUE;
}




function benchmark(Array $methods, Array &$target){    
    foreach($methods as $method){
        $start = microtime(true);
        for ($i = 0; $i < 1000; $i++)
            $dummy = call_user_func($method, $target);

        $end = microtime(true);
        echo "Time taken with $method = ".round(($end-$start)*1000.0,3)."ms\n";
    }
}



$targets = [
    'Huge array' => range(0, 30000),
    'Small array' => range(0, 1000),
];
$methods = [
    'method_1',
    'method_2',
    'method_3',
    'method_4',
];
foreach($targets as $targetName => $target){
    echo "==== Benchmark using $targetName ====\n";
    benchmark($methods, $target);
    echo "\n";
}

results:

==== Benchmark using Huge array ====
Time taken with method_1 = 5504.632ms
Time taken with method_2 = 4509.445ms
Time taken with method_3 = 8614.883ms
Time taken with method_4 = 2720.934ms

==== Benchmark using Small array ====
Time taken with method_1 = 77.159ms
Time taken with method_2 = 130.03ms
Time taken with method_3 = 160.866ms
Time taken with method_4 = 69.946ms

So many problems in so few lines. I probably forget some:

• argv[0] is the program name, not the first argument;
• if you want to read in a variable, you have to allocate its memory
• one never loops on feof, one loops on an IO function until it fails, feof then serves to determinate the reason of failure,
• sscanf is there to parse a line, if you want to parse a file, use fscanf,
• "%s" will stop at the first space as a format for the ?scanf family
• to read a line, the standard function is fgets,
• returning 1 from main means failure

So

#include <stdio.h>

int main(int argc, char* argv[])
{
    char const* const fileName = argv[1]; /* should check that argc > 1 */
    FILE* file = fopen(fileName, "r"); /* should check the result */
    char line[256];

    while (fgets(line, sizeof(line), file)) {
        /* note that fgets don't strip the terminating \n, checking its
           presence would allow to handle lines longer that sizeof(line) */
        printf("%s", line); 
    }
    /* may check feof here to make a difference between eof and io failure -- network
       timeout for instance */

    fclose(file);

    return 0;
}

Quick function based on responses.

loadCSS = function(href) {

  var cssLink = $("<link>");
  $("head").append(cssLink); //IE hack: append before setting href

  cssLink.attr({
    rel:  "stylesheet",
    type: "text/css",
    href: href
  });

};

Usage:

loadCSS("/css/file.css");

I have noticed also that even if you specify your website under secion - Website With Facebook Login -> Site url as e.g. http://example.com, but if your App Domains section is empty, and you open website as www.example.com you will get this error, too. To avoid it in "App Domains" section write example.com, that will allow subdomains, like www.example.com, something.example.com etc

For people who want to use another diff tool not listed in git, say with nvim. here is what I ended up using:

git config --global alias.d difftool -x <tool name>

In my case, I set <tool name> to nvim -d and invoke the diff command with

git d <file>

Performance test:

http://jsperf.com/array-clear-methods/3

a = []; // 37% slower
a.length = 0; // 89% slower
a.splice(0, a.length)  // 97% slower
while (a.length > 0) {
    a.pop();
} // Fastest

The only time I ever use private variables is when I need to do other things when writing to or reading from the variable and as such I need to force the use of a setter and/or getter.

Again this goes to culture, as already stated. I've been working on projects where reading and writing other classes variables was free-for-all. When one implementation became deprecated it took a lot longer to identify all code paths that used that function. When use of setters and getters was forced, a debug statement could easily be written to identify that the deprecated method had been called and the code path that calls it.

When you are on a project where anyone can write an extension, notifying users about deprecated methods that are to disappear in a few releases hence is vital to keep module breakage at a minimum upon upgrades.

So my answer is; if you and your colleagues maintain a simple code set then protecting class variables is not always necessary. If you are writing an extensible system then it becomes imperative when changes to the core is made that needs to be caught by all extensions using the code.

You are using Lists, concrete ArrayList. ArrayList also implements Collection interface. Collection interface has sort method which is used to sort the elements present in the specified list of Collection in ascending order. This will be the quickest and possibly the best way for your case.

Sorting a list in ascending order can be performed as default operation on this way:

Collections.sort(list);

Sorting a list in descending order can be performed on this way:

Collections.reverse(list);

According to these facts, your solution has to be written like this:

public class tes 
{
    public static void main(String args[])
    {
        List<Integer> lList = new ArrayList<Integer>();
        lList.add(4);
        lList.add(1);
        lList.add(7);
        lList.add(2);
        lList.add(9);
        lList.add(1);
        lList.add(5);

        Collections.sort(lList);
        for(int i=0; i<lList.size();i++ )
        {
            System.out.println(lList.get(i));
        }
     }
}

More about Collections you can read here.

The problem here is that in your code the program is calling 'null.length()' which is not defined if the argument passed to the function is null. That's why the exception is thrown.

You don't.

If you want to extend Person with Student, just do:

public class Student extends Person
{
}

And make sure, when you compile both classes, one can find the other one.

What IDE are you using?

First of all don't use 'list' as variable name.

If you have simple dictionaries with unique keys then you can do the following(note that new dictionary object with all items from sub-dictionaries will be created):

res  = {}
for line in listOfDicts:
   res.update(line)
res['d']
>>> 4

Otherwise:

getValues = lambda key,inputData: [subVal[key] for subVal in inputData if key in subVal]
getValues('d', listOfDicts)
>>> [4]

Or very base:

def get_value(listOfDicts, key):
    for subVal in listOfDicts:
        if key in subVal:
            return subVal[key]

Try with this piece of code.

.ui-datepicker{ z-index:1151 !important; }

will solve the problem when you are using bootstrap V3

In Swift5 ans Xcode 10

Add two textfields with Save and Cancel actions and read TextFields text data

func alertWithTF() {
    //Step : 1
    let alert = UIAlertController(title: "Great Title", message: "Please input something", preferredStyle: UIAlertController.Style.alert )
    //Step : 2
    let save = UIAlertAction(title: "Save", style: .default) { (alertAction) in
        let textField = alert.textFields![0] as UITextField
        let textField2 = alert.textFields![1] as UITextField
        if textField.text != "" {
            //Read TextFields text data
            print(textField.text!)
            print("TF 1 : \(textField.text!)")
        } else {
            print("TF 1 is Empty...")
        }

        if textField2.text != "" {
            print(textField2.text!)
            print("TF 2 : \(textField2.text!)")
        } else {
            print("TF 2 is Empty...")
        }
    }

    //Step : 3
    //For first TF
    alert.addTextField { (textField) in
        textField.placeholder = "Enter your first name"
        textField.textColor = .red
    }
    //For second TF
    alert.addTextField { (textField) in
        textField.placeholder = "Enter your last name"
        textField.textColor = .blue
    }

    //Step : 4
    alert.addAction(save)
    //Cancel action
    let cancel = UIAlertAction(title: "Cancel", style: .default) { (alertAction) in }
    alert.addAction(cancel)
    //OR single line action
    //alert.addAction(UIAlertAction(title: "Cancel", style: .default) { (alertAction) in })

    self.present(alert, animated:true, completion: nil)

Just to follow up on this since the top answer recommends not using materializecss... in the current version of materialize you no longer need to initialize selects.

Sleep meaning that thread is do nothing. Time is too large beacuse anthor thread query,but not disconnect server, default wait_timeout=28800;so you can set values smaller,eg 10. also you can kill the thread.

It works for me, by using double quotes around variables.

I am using batch script to call powershell Send-MailMessage

Batch Script:send_email.bat

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe  -command 'E:\path\send_email.ps1

Send-MailMessage -From "noreply@$env:computername" -To '<[email protected]>' -Subject 'Blah Blah' -SmtpServer  'smtp.domain.com'  -Attachments 'E:\path\file.log' -BODY "Blah Blah on Host: $env:computername "

The easiest thing is if you can make the WPF bitmap from a file directly.

Otherwise you will have to use System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap.

I'm assuming you just want to find out how much trouble you're getting yourself into prior to actually attempting the merge...and resetting to the last commit after a failed merge is relatively easy so I wouldn't be surprised if that is the intended approach.

That said, if you really don't want to touch your existing files in the working tree - you could create a patch and test it against the target branch. This also has the benefit of showing exactly what changes were made to which files - just open up the patch file in a text editor.

git checkout -b mycrazybranch
[change some stuff...]
git add .
git commit -m "changed some stuff"
git format-patch master --stdout > crazy.patch
git checkout master
git apply crazy.patch --check
[all good! cleanup...]
rm crazy.patch

As you can see, this will create a patch file, you can then test it with --check and see if there are any errors, then remove the patch file.

I think the most logical answer in this regard is to set the system clock to the relevant feature.

I've just found a great tool for that need, it is called tabulate.

It prints tabular data and works with DataFrame.

from tabulate import tabulate
import pandas as pd

df = pd.DataFrame({'col_two' : [0.0001, 1e-005 , 1e-006, 1e-007],
                   'column_3' : ['ABCD', 'ABCD', 'long string', 'ABCD']})
print(tabulate(df, headers='keys', tablefmt='psql'))

+----+-----------+-------------+
|    |   col_two | column_3    |
|----+-----------+-------------|
|  0 |    0.0001 | ABCD        |
|  1 |    1e-05  | ABCD        |
|  2 |    1e-06  | long string |
|  3 |    1e-07  | ABCD        |
+----+-----------+-------------+

Note:

To suppress row indices for all types of data, pass showindex="never" or showindex=False.

Kill the braces.

var defaults = {
 backgroundcolor: '#000',
 color: '#fff',
 weekdays: ['sun','mon','tue','wed','thu','fri','sat']
};

I find it more convenient to make a connection using a procedural programming language (like Python) and do these types of queries.

import psycopg2
connection_psql = psycopg2.connect( user="admin_user"
                                  , password="***"
                                  , port="5432"
                                  , database="myDB"
                                  , host="[ENDPOINT]")
cursor_psql = connection_psql.cursor()

myList = [...]
for item in myList:
  cursor_psql.execute('''
    -- The query goes here
  ''')

connection_psql.commit()
cursor_psql.close()

I figured it out. In order to save your Jenkins data on other drive you'll need to do the following:

Workspace Root Directory: E:\Jenkins\${ITEM_FULL_NAME}\workspace
Build Record Root Directory: E:\Jenkins\${ITEM_FULL_NAME}\builds

Here is one solution that I would not recommend, but might be useful in some situations where modules were simply not generated:

import os
import sys
parent_dir_name = os.path.dirname(os.path.dirname(os.path.realpath(__file__)))
sys.path.append(parent_dir_name + "/your_dir")
import your_script
your_script.a_function()

One Eclipse window was already opened on my machine and when I tried to open another Eclipse instance, I got this error. I just closed my open Eclipse windows and then launched another. And there was no such error anymore :)

Why not just change the second line to

document.location.href="www.example.com/index.php?id=" + $(this).attr('id');

From here:

"You can also refer to the properties of the data object via that object, instead of accessing them as variables." Meaning that for OP's case this will work (with a significantly smaller change than other possible solutions):

<% if (obj.date) { %><span class="date"><%= date %></span><% }  %>

• matplotlib is somewhat different from when the original answer was posted
• matplotlib.pyplot.text
• matplotlib.axes.Axes.text

import matplotlib.pyplot as plt

plt.figure(figsize=(6, 6))
plt.text(0.1, 0.9, 'text', size=15, color='purple')

# or 

fig, axe = plt.subplots(figsize=(6, 6))
axe.text(0.1, 0.9, 'text', size=15, color='purple')

Output of Both

• From matplotlib: Precise text layout
  • You can precisely layout text in data or axes coordinates.

import matplotlib.pyplot as plt

# Build a rectangle in axes coords
left, width = .25, .5
bottom, height = .25, .5
right = left + width
top = bottom + height
ax = plt.gca()
p = plt.Rectangle((left, bottom), width, height, fill=False)
p.set_transform(ax.transAxes)
p.set_clip_on(False)
ax.add_patch(p)


ax.text(left, bottom, 'left top',
        horizontalalignment='left',
        verticalalignment='top',
        transform=ax.transAxes)

ax.text(left, bottom, 'left bottom',
        horizontalalignment='left',
        verticalalignment='bottom',
        transform=ax.transAxes)

ax.text(right, top, 'right bottom',
        horizontalalignment='right',
        verticalalignment='bottom',
        transform=ax.transAxes)

ax.text(right, top, 'right top',

ax.text(right, bottom, 'center top',
        horizontalalignment='center',
        verticalalignment='top',
        transform=ax.transAxes)

ax.text(left, 0.5 * (bottom + top), 'right center',
        horizontalalignment='right',
        verticalalignment='center',
        rotation='vertical',
        transform=ax.transAxes)

ax.text(left, 0.5 * (bottom + top), 'left center',
        horizontalalignment='left',
        verticalalignment='center',
        rotation='vertical',
        transform=ax.transAxes)

ax.text(0.5 * (left + right), 0.5 * (bottom + top), 'middle',
        horizontalalignment='center',
        verticalalignment='center',
        transform=ax.transAxes)

        verticalalignment='center',
        rotation='vertical',

What we do, is to create two tables for each multilingual object.

E.g. the first table contains only language-neutral data (primary key, etc.) and the second table contains one record per language, containing the localized data plus the ISO code of the language.

In some cases we add a DefaultLanguage field, so that we can fall-back to that language if no localized data is available for a specified language.

Example:

Table "Product":
----------------
ID                 : int
<any other language-neutral fields>


Table "ProductTranslations"
---------------------------
ID                 : int      (foreign key referencing the Product)
Language           : varchar  (e.g. "en-US", "de-CH")
IsDefault          : bit
ProductDescription : nvarchar
<any other localized data>

With this approach, you can handle as many languages as needed (without having to add additional fields for each new language).

Update (2014-12-14): please have a look at this answer, for some additional information about the implementation used to load multilingual data into an application.

SQL does not do that. The order of the tuples in the table are not ordered by insertion date. A lot of people include a column that stores that date of insertion in order to get around this issue.

Almost what I wanted @Ralph, but here is the best answer. It'll solve your code problems:

1. it exports just the hardcoded sheet named "Sheet1";
2. it always exports to the same temp file, overwriting it;
3. it ignores the locale separation char.

To solve these problems, and meet all my requirements, I've adapted the code from here. I've cleaned it a little to make it more readable.

Option Explicit
Sub ExportAsCSV()
 
    Dim MyFileName As String
    Dim CurrentWB As Workbook, TempWB As Workbook
     
    Set CurrentWB = ActiveWorkbook
    ActiveWorkbook.ActiveSheet.UsedRange.Copy
 
    Set TempWB = Application.Workbooks.Add(1)
    With TempWB.Sheets(1).Range("A1")
      .PasteSpecial xlPasteValues
      .PasteSpecial xlPasteFormats
    End With        

    Dim Change below to "- 4"  to become compatible with .xls files
    MyFileName = CurrentWB.Path & "\" & Left(CurrentWB.Name, Len(CurrentWB.Name) - 5) & ".csv"
     
    Application.DisplayAlerts = False
    TempWB.SaveAs Filename:=MyFileName, FileFormat:=xlCSV, CreateBackup:=False, Local:=True
    TempWB.Close SaveChanges:=False
    Application.DisplayAlerts = True
End Sub

There are still some small thing with the code above that you should notice:

1. .Close and DisplayAlerts=True should be in a finally clause, but I don't know how to do it in VBA
2. It works just if the current filename has 4 letters, like .xlsm. Wouldn't work in .xls excel old files. For file extensions of 3 chars, you must change the - 5 to - 4 when setting MyFileName.
3. As a collateral effect, your clipboard will be substituted with current sheet contents.

Edit: put Local:=True to save with my locale CSV delimiter.

Update: Latest ActionBar (Title) pattern:

FYI, ActionBar was introduced in API Level 11. ActionBar is a window feature at the top of the Activity that may display the activity title, navigation modes, and other interactive items like search.

I exactly remember about customizing title bar and making it consistent through the application. So I can make a comparison with the earlier days and can list some of the advantages of using ActionBar:

1. It offers your users a familiar interface across applications that the system gracefully adapts for different screen configurations.
2. Developers don't need to write much code for displaying the Activity Title, icons and navigation modes because ActionBar is already ready with top level abstraction.

For example:

=> Normal way,

getActionBar().setTitle("Hello world App");   
getSupportActionBar().setTitle("Hello world App");  // provide compatibility to all the versions

=> Customizing Action Bar,

For example:

@Override
public void setActionBar(String heading) {
    // TODO Auto-generated method stub

    com.actionbarsherlock.app.ActionBar actionBar = getSupportActionBar();
    actionBar.setHomeButtonEnabled(true);
    actionBar.setDisplayHomeAsUpEnabled(false);
    actionBar.setDisplayShowHomeEnabled(false);
    actionBar.setBackgroundDrawable(new ColorDrawable(getResources().getColor(R.color.title_bar_gray)));
    actionBar.setTitle(heading);
    actionBar.show();

}

Styling the Action Bar:

The ActionBar provides you with basic and familiar looks, navigation modes and other quick actions to perform. But that doesn't mean it looks the same in every app. You can customize it as per your UI and design requirements. You just have to define and write styles and themes.

Read more at: Styling the Action Bar

And if you want to generate styles for ActionBar then this Style Generator tool can help you out.

=================================================================================

Old: Earlier days:

=> Normal way,

you can Change the Title of each screen (i.e. Activity) by setting their Android:label

   <activity android:name=".Hello_World"
                  android:label="This is the Hello World Application">
   </activity>

=> Custom - Title - bar

But if you want to Customize title-bar in your own way, i.e. Want to put Image icon and custom-text, then the following code works for me:

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"/>

titlebar.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="400dp" 
  android:layout_height="fill_parent"
  android:orientation="horizontal">

<ImageView android:id="@+id/ImageView01" 
            android:layout_width="57dp" 
            android:layout_height="wrap_content"
            android:background="@drawable/icon1"/>

<TextView 

  android:id="@+id/myTitle" 
  android:text="This is my new title" 
  android:layout_width="fill_parent" 
  android:layout_height="fill_parent" 
  android:textColor="@color/titletextcolor"
   />
</LinearLayout>

TitleBar.java

public class TitleBar extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        final boolean customTitleSupported = 
                requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(R.layout.main);
        if (customTitleSupported) {
            getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,
                R.layout.titlebar);
        }
        final TextView myTitleText = (TextView) findViewById(R.id.myTitle);
        if (myTitleText != null) {
            myTitleText.setText("NEW TITLE");
            // user can also set color using "Color" and then
            // "Color value constant"
            // myTitleText.setBackgroundColor(Color.GREEN);
        }
    }
}

strings.xml

The strings.xml file is defined under the values folder.

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, Set_Text_TitleBar!</string>
    <string name="app_name">Set_Text_TitleBar</string>
    <color name="titlebackgroundcolor">#3232CD</color>
    <color name="titletextcolor">#FFFF00</color>
</resources>

When you have multiple git account and you want different ssh key

You have to follow same step for generating the ssh key, but be sure you

ssh-keygen -t ed25519 -C "[email protected]" 

Enter the path you want to save(Ex: my-pc/Desktop/.ssh/ed25519)

Add the public key to your gitlab (How to adding ssh key to gitlab)

You have to new ssh identity using the below comand

ssh-add ~/my-pc/Desktop/.ssh/ed25519

Yes, session doesn't go hand in hand with Rest API and also we should avoid this practices. But as per requirements we need to maintain session somehow such that in every request client server can exchange or maintain state or data. So, the best way to achieve this without breaking the REST protocols is communicate through token like JWT.

Many of the other answers are all well but if you want an informational tooltip instead of a fullblown window then do this: after enabling it using @Ahmad's answer then click on the little pin on the upper right corner:

After this the method information will appear on a tooltip like almost every other mainstream IDE.

.combobox_selector ul {
    padding: 0;
    margin: 0;
    list-style: none;
    border:1px solid #CCC;
    height: 200px;
    overflow: auto;
    overflow-x: hidden;
}

sets 200px scrolldown size, overflow-x hides any horizontal scrollbar.

In Bootstrap 4 one should use the text-center class to align inline-blocks.

NOTE: text-align:center; defined in a custom class you apply to your parent element will work regardless of the Bootstrap version you are using. And that's exactly what .text-center applies.

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">_x000D_
_x000D_
<div class="container">_x000D_
  <div class="row">_x000D_
    <div class="col text-center">_x000D_
      <button class="btn btn-default">Centered button</button>_x000D_
    </div>_x000D_
  </div>_x000D_
</div>

If the content to be centered is block or flex (not inline-), one could use flexbox to center it:

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css">_x000D_
_x000D_
<div class="d-flex justify-content-center">_x000D_
  <button class="btn btn-default">Centered button</button>_x000D_
</div>

... which applies display: flex; justify-content: center to parent.

Note: don't use .row.justify-content-center instead of .d-flex.justify-content-center, as .row applies negative margins on certain responsiveness intervals, which results into unexpected horizontal scrollbars (unless .row is a direct child of .container, which applies lateral padding to counteract the negative margin, on the correct responsiveness intervals). If you must use .row, for whatever reason, override its margin and padding with .m-0.p-0, in which case you end up with pretty much the same styles as .d-flex.

Important note: The second solution is problematic when the centered content (the button) exceeds the width of the parent (.d-flex) especially when the parent has viewport width, specifically because it makes it impossible to horizontally scroll to the start of the content (left-most).
So don't use it when the content to be centered could become wider than the available parent width and all content should be accessible.

var str = "I'm a very^ we!rd* Str!ng.";
$('body').html(str.replace(/[^a-z0-9\s]/gi, " ").replace(/^\s+|\s+$|\s+(?=\s)/g, "").replace(/[_\s]/g, "-").toLowerCase());

First regex remove special characters with spaces than remove extra spaces from string and the last regex replace space with "-"

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

BEGIN TRANSACTION

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

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

COMMIT

select right(rtrim('94342KMR'),3)

This will fetch the last 3 right string.

select substring(rtrim('94342KMR'),1,len('94342KMR')-3)

This will fetch the remaining Characters.

First add HTML code:

<form action="" method="post">
<input type="text" name="search">
<input type="submit" name="submit" value="Search">
</form>

Now added PHP code:

<?php
$search_value=$_POST["search"];
$con=new mysqli($servername,$username,$password,$dbname);
if($con->connect_error){
    echo 'Connection Faild: '.$con->connect_error;
    }else{
        $sql="select * from information where First_Name like '%$search_value%'";

        $res=$con->query($sql);

        while($row=$res->fetch_assoc()){
            echo 'First_name:  '.$row["First_Name"];


            }       

        }
?>

SELECT * FROM news WHERE date > DATEADD(d,-1,GETDATE())

Java commons-io has a FileAlterationObserver. it does polling in combination with a FileAlterationMonitor. Similar to commons VFS. The advantag is that it has much less dependencies.

edit: Less dependencies is not true, they are optional for VFS. But it uses java File instead of the VFS abstraction layer.

TextView textv = (TextView) findViewById(R.id.textview1);
textv.setShadowLayer(1, 0, 0, Color.BLACK);

Your calls are made recursively which pushes functions on to the stack infinitely that causes max call stack exceeded error due to recursive behavior. Instead try using setTimeout which is a callback.

Also based on your markup your selector is wrong. it should be #advisersDiv

Demo

function fadeIn() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).addClass("pulse");
    setTimeout(fadeOut,1); //<-- Provide any delay here
};

function fadeOut() {
    $('#pulseDiv').find('div#advisersDiv').delay(400).removeClass("pulse");
    setTimeout(fadeIn,1);//<-- Provide any delay here
};
fadeIn();

You can try this it will help for you.You can't get path from WhatsApp directly.If you need an file path first copy file and send new file path. Using the code below

 public static String getFilePathFromURI(Context context, Uri contentUri) {
    String fileName = getFileName(contentUri);
    if (!TextUtils.isEmpty(fileName)) {
        File copyFile = new File(TEMP_DIR_PATH  + fileName+".jpg");
        copy(context, contentUri, copyFile);
        return copyFile.getAbsolutePath();
    }
    return null;
}

public static String getFileName(Uri uri) {
    if (uri == null) return null;
    String fileName = null;
    String path = uri.getPath();
    int cut = path.lastIndexOf('/');
    if (cut != -1) {
        fileName = path.substring(cut + 1);
    }
    return fileName;
}

public static void copy(Context context, Uri srcUri, File dstFile) {
    try {
        InputStream inputStream = context.getContentResolver().openInputStream(srcUri);
        if (inputStream == null) return;
        OutputStream outputStream = new FileOutputStream(dstFile);
        IOUtils.copy(inputStream, outputStream);
        inputStream.close();
        outputStream.close();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Then IOUtils class is like below

public class IOUtils {



private static final int BUFFER_SIZE = 1024 * 2;

private IOUtils() {
    // Utility class.
}

public static int copy(InputStream input, OutputStream output) throws Exception, IOException {
    byte[] buffer = new byte[BUFFER_SIZE];

    BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);
    BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);
    int count = 0, n = 0;
    try {
        while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {
            out.write(buffer, 0, n);
            count += n;
        }
        out.flush();
    } finally {
        try {
            out.close();
        } catch (IOException e) {
            Log.e(e.getMessage(), e.toString());
        }
        try {
            in.close();
        } catch (IOException e) {
            Log.e(e.getMessage(), e.toString());
        }
    }
    return count;
}


}

this happened after 27,use targetSdkVersion 26 replace, wait for google fixed it

You can use %x or %X or %p; all of them are correct.

• If you use %x, the address is given as lowercase, for example: a3bfbc4
• If you use %X, the address is given as uppercase, for example: A3BFBC4

Both of these are correct.

If you use %x or %X it's considering six positions for the address, and if you use %p it's considering eight positions for the address. For example:
