SWIFT4 - Easy and elegant way of decoding JSON strings to Struct.

First step - encode String to Data with .utf8 encoding.

Than decode your Data to YourDataStruct.

struct YourDataStruct: Codable {

let type, id: String

init(_ json: String, using encoding: String.Encoding = .utf8) throws {
    guard let data = json.data(using: encoding) else {
        throw NSError(domain: "JSONDecoding", code: 0, userInfo: nil)
    }
    try self.init(data: data)
}

init(data: Data) throws {
    self = try JSONDecoder().decode(YourDataStruct.self, from: data)
}                                                                      
}

do { let successResponse = try WSDeleteDialogsResponse(response) }
} catch {}

As string data types have variable length, it is by default stored as object type. I faced this problem after treating missing values too. Converting all those columns to type 'category' before label encoding worked in my case.

df[cat]=df[cat].astype('category')

And then check df.dtypes and perform label encoding.

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

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

Refer the solution at: http://www.compilr.org/compile-and-run-java-programs/

Hope that solves, for both compiling and running the classes within sublime..... You can see my script in the comments section to try it out in case of mac...

EDIT: Unfortunately, the above link is broken now. It detailed all the steps required for comiling and running java within sublime text. Anyways, for mac or linux systems, the below should work:

modify javac.sublime-build file to:

#!/bin/sh

classesDir="/Users/$USER/Desktop/java/classes/"
codeDir="/Users/$USER/Desktop/java/code/"
[ -f "$classesDir/$1.class" ] && rm $classesDir/$1.class
for file in $1.java
do
echo "Compiling $file........"
javac -d $classesDir $codeDir/$file
done
if [ -f "$classesDir/$1.class" ]
then
echo "-----------OUTPUT-----------"
java -cp $classesDir $1
else
echo " "
fi

Here, I have made a folder named "java" on the Desktop and subfolders "classes" and "code" for maintaining the .class and .java files respectively, you can modify in your own way.

A foreign key with a cascade delete means that if a record in the parent table is deleted, then the corresponding records in the child table will automatically be deleted. This is called a cascade delete.

You are saying in a opposite way, this is not that when you delete from child table then records will be deleted from parent table.

UPDATE 1:

ON DELETE CASCADE option is to specify whether you want rows deleted in a child table when corresponding rows are deleted in the parent table. If you do not specify cascading deletes, the default behaviour of the database server prevents you from deleting data in a table if other tables reference it.

If you specify this option, later when you delete a row in the parent table, the database server also deletes any rows associated with that row (foreign keys) in a child table. The principal advantage to the cascading-deletes feature is that it allows you to reduce the quantity of SQL statements you need to perform delete actions.

So it's all about what will happen when you delete rows from Parent table not from child table.

So in your case when user removes entries from CATs table then rows will be deleted from books table. :)

Hope this helps you :)

Do the following, download SQLLite Database Browser from here:

Locate your db. file in your phone.

Then, as soon you install the program go to: "Browse Data", you will see all the SMS there!!

You can actually export the data to an excel file or SQL.

Source article: Passing a list as an argument to a vararg method

Use the toArray(T[] arr) method.

.getMap(locations.toArray(new WorldLocation[locations.size()]))

(toArray(new WorldLocation[0]) also works, but you would allocate a zero-length array for no reason.)

Here's a complete example:

public static void method(String... strs) {
    for (String s : strs)
        System.out.println(s);
}

...
    List<String> strs = new ArrayList<String>();
    strs.add("hello");
    strs.add("world");
    
    method(strs.toArray(new String[strs.size()]));
    //     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...

I have written a post exactly about this matter. It basically makes use of a routeRegistrar that iterates through files in the folder /controllers calling its function init. Function init takes the express app variable as a parameter so you can register your routes the way you want.

var fs = require("fs");
var express = require("express");
var app = express();

var controllersFolderPath = __dirname + "/controllers/";
fs.readdirSync(controllersFolderPath).forEach(function(controllerName){
    if(controllerName.indexOf("Controller.js") !== -1){
        var controller = require(controllersFolderPath + controllerName);
        controller.init(app);
    }
});

app.listen(3000);

As Mystere Man suggested, getting just a view first and then again making an ajax call again to get the json result is unnecessary in this case. that is 2 calls to the server. I think you can directly return an HTML table of Users in the first call.

We will do this in this way. We will have a strongly typed view which will return the markup of list of users to the browser and this data is being supplied by an action method which we will invoke from our browser using an http request.

Have a ViewModel for the User

public class UserViewModel
{
  public int UserID { set;get;}
  public string FirstName { set;get;}
   //add remaining properties as per your requirement

}

and in your controller have a method to get a list of Users

public class UserController : Controller
{

   [HttpGet]
   public ActionResult List()
   {
     List<UserViewModel> objList=UserService.GetUsers();  // this method should returns list of  Users
     return View("users",objList)        
   }
}

Assuming that UserService.GetUsers() method will return a List of UserViewModel object which represents the list of usres in your datasource (Tables)

and in your users.cshtml ( which is under Views/User folder),

 @model List<UserViewModel>

 <table>

 @foreach(UserViewModel objUser in Model)
 {
   <tr>
      <td>@objUser.UserId.ToString()</td>
      <td>@objUser.FirstName</td>
   </tr>
 }
 </table>

All Set now you can access the url like yourdomain/User/List and it will give you a list of users in an HTML table.

for this find the given Object in an Array, a basic usage example of _.find

const array = 
[
{
    description: 'object1', id: 1
},
{
    description: 'object2', id: 2
},
{
    description: 'object3', id: 3
},
{
    description: 'object4', id: 4
}
];

this would work well

q = _.find(array, {id:'4'}); // delete id

console.log(q); // {description: 'object4', id: 4}

_.find will help with returning an element in an array, rather than it’s index. So if you have an array of objects and you want to find a single object in the array by a certain key value pare _.find is the right tools for the job.

JAXB is an ideal solution. But you do not necessarily need xsd and xjc for that. More often than not you don't have an xsd but you know what your xml is. Simply analyze your xml, e.g.,

<customer id="100">
    <age>29</age>
    <name>mkyong</name>
</customer>

Create necessary model class(es):

@XmlRootElement
public class Customer {

    String name;
    int age;
    int id;

    public String getName() {
        return name;
    }

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

    public int getAge() {
        return age;
    }

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

    public int getId() {
        return id;
    }

    @XmlAttribute
    public void setId(int id) {
        this.id = id;
    }

}

Try to unmarshal:

JAXBContext jaxbContext = JAXBContext.newInstance(Customer.class);
Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
Customer customer = (Customer) jaxbUnmarshaller.unmarshal(new File("C:\\file.xml"));

Check results, fix bugs!

I think it's just because you have forgot HTTP METHOD. The default HTTP method of request is GET.

You should add method: 'POST' and your code will work if your backend receive the post method.

var req = require('request');

req.post({
   url: 'someUrl',
   form: { username: 'user', password: '', opaque: 'someValue', logintype: '1'},
   headers: { 
      'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
      'Content-Type' : 'application/x-www-form-urlencoded' 
   },
   method: 'POST'
  },

  function (e, r, body) {
      console.log(body);
  });

See also here: http://sqlblog.com/blogs/alexander_kuznetsov/archive/2008/06/26/fun-with-dbcc-chekident.aspx

This is documented behavior, why do you run CHECKIDENT if you recreate the table, in that case skip the step or use TRUNCATE (if you don't have FK relationships)

Change CI index.php file to:

if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

if (defined('ENVIRONMENT')){
    switch (ENVIRONMENT){
        case 'development':
            error_reporting(E_ALL);
        break;

        case 'testing':
        case 'production':
            error_reporting(0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

IF PHP errors are off, but any MySQL errors are still going to show, turn these off in the /config/database.php file. Set the db_debug option to false:

$db['default']['db_debug'] = FALSE; 

Also, you can use active_group as development and production to match the environment https://www.codeigniter.com/user_guide/database/configuration.html

$active_group = 'development';


$db['development']['hostname'] = 'localhost';
$db['development']['username'] = '---';
$db['development']['password'] = '---';
$db['development']['database'] = '---';
$db['development']['dbdriver'] = 'mysql';
$db['development']['dbprefix'] = '';
$db['development']['pconnect'] = TRUE;

$db['development']['db_debug'] = TRUE;

$db['development']['cache_on'] = FALSE;
$db['development']['cachedir'] = '';
$db['development']['char_set'] = 'utf8';
$db['development']['dbcollat'] = 'utf8_general_ci';
$db['development']['swap_pre'] = '';
$db['development']['autoinit'] = TRUE;
$db['development']['stricton'] = FALSE;



$db['production']['hostname'] = 'localhost';
$db['production']['username'] = '---';
$db['production']['password'] = '---';
$db['production']['database'] = '---';
$db['production']['dbdriver'] = 'mysql';
$db['production']['dbprefix'] = '';
$db['production']['pconnect'] = TRUE;

$db['production']['db_debug'] = FALSE;

$db['production']['cache_on'] = FALSE;
$db['production']['cachedir'] = '';
$db['production']['char_set'] = 'utf8';
$db['production']['dbcollat'] = 'utf8_general_ci';
$db['production']['swap_pre'] = '';
$db['production']['autoinit'] = TRUE;
$db['production']['stricton'] = FALSE;

If the radiobutton-checked event occurs before the content of the window is loaded fully, i.e. the ellipse is loaded fully, such an exception will be thrown. So check if the UI of the window is loaded (probably by Window_ContentRendered event, etc.).

You could also use the parse_date_time function from the lubridate package:

library(lubridate)
day<-"31/08/2011"
as.Date(parse_date_time(day,"dmy"))
[1] "2011-08-31"

parse_date_time returns a POSIXct object, so we use as.Date to get a date object. The first argument of parse_date_time specifies a date vector, the second argument specifies the order in which your format occurs. The orders argument makes parse_date_time very flexible.

Using Nested Scroll View instead of Scroll View solved my problem

<LinearLayout> <!--Main Layout -->
   <android.support.v4.widget.NestedScrollView>
     <LinearLayout > <!--Nested Scoll View enclosing Layout -->`

       <View > <!-- upper content --> 
       <RecyclerView >


     </LinearLayout > 
   </android.support.v4.widget.NestedScrollView>
</LinearLayout>

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

Since you look like you're going to be using this in a linux/cygwin environment, you want to use popen. It's like opening a file, only you'll get the executing programs stdout, so you can use your normal fscanf, fread etc.

You could use Spring AOP aproach. For example if you have some service, that needs to know current principal. You could introduce custom annotation i.e. @Principal , which indicate that this Service should be principal dependent.

public class SomeService {
    private String principal;
    @Principal
    public setPrincipal(String principal){
        this.principal=principal;
    }
}

Then in your advice, which I think needs to extend MethodBeforeAdvice, check that particular service has @Principal annotation and inject Principal name, or set it to 'ANONYMOUS' instead.

1. Open SQL Server Management Studio
2. Connect to the database engine for which you need the port number

3. Run the below query against the database

   select distinct local_net_address, local_tcp_port from sys.dm_exec_connections where local_net_address is not null

The above query shows the local IP as well as the listening Port number

If you want one element with the corresponding one you could do

Enumerable.Range(0, List1.Count).All(x => List1[x] == List2[x]);

That will return true if every item is equal to the corresponding one on the second list

If that's almost but not quite what you want it would help if you elaborated more.

I assert that you are using HiveServer2, which is the reason that makes the code doesn't work.

You may use pyhs2 to access your Hive correctly and the example code like that:

import pyhs2

with pyhs2.connect(host='localhost',
               port=10000,
               authMechanism="PLAIN",
               user='root',
               password='test',
               database='default') as conn:
    with conn.cursor() as cur:
        #Show databases
        print cur.getDatabases()

        #Execute query
        cur.execute("select * from table")

        #Return column info from query
        print cur.getSchema()

        #Fetch table results
        for i in cur.fetch():
            print i

Attention that you may install python-devel.x86_64 cyrus-sasl-devel.x86_64 before installing pyhs2 with pip.

Wish this can help you.

This one-liner should work too:

(cd /path/to/your/app && npm start)

Note that the current directory will be changed to /path/to/your/app after executing this command. To preserve the working directory:

(cd /path/to/your/app && npm start && cd -)

I used this solution because a program configuration file I was editing back then didn't support specifying command line arguments.

git remote add origin <remote_repo_url>
git push --all origin

If you want to set all of your branches to automatically use this remote repo when you use git pull, add --set-upstream to the push:

git push --all --set-upstream origin

How would you check if a variable is a dictionary in Python?

This is an excellent question, but it is unfortunate that the most upvoted answer leads with a poor recommendation, type(obj) is dict.

(Note that you should also not use dict as a variable name - it's the name of the builtin object.)

If you are writing code that will be imported and used by others, do not presume that they will use the dict builtin directly - making that presumption makes your code more inflexible and in this case, create easily hidden bugs that would not error the program out.

I strongly suggest, for the purposes of correctness, maintainability, and flexibility for future users, never having less flexible, unidiomatic expressions in your code when there are more flexible, idiomatic expressions.

is is a test for object identity. It does not support inheritance, it does not support any abstraction, and it does not support the interface.

So I will provide several options that do.

Supporting inheritance:

This is the first recommendation I would make, because it allows for users to supply their own subclass of dict, or a OrderedDict, defaultdict, or Counter from the collections module:

if isinstance(any_object, dict):

But there are even more flexible options.

Supporting abstractions:

from collections.abc import Mapping

if isinstance(any_object, Mapping):

This allows the user of your code to use their own custom implementation of an abstract Mapping, which also includes any subclass of dict, and still get the correct behavior.

Use the interface

You commonly hear the OOP advice, "program to an interface".

This strategy takes advantage of Python's polymorphism or duck-typing.

So just attempt to access the interface, catching the specific expected errors (AttributeError in case there is no .items and TypeError in case items is not callable) with a reasonable fallback - and now any class that implements that interface will give you its items (note .iteritems() is gone in Python 3):

try:
    items = any_object.items()
except (AttributeError, TypeError):
    non_items_behavior(any_object)
else: # no exception raised
    for item in items: ...

Perhaps you might think using duck-typing like this goes too far in allowing for too many false positives, and it may be, depending on your objectives for this code.

Conclusion

Don't use is to check types for standard control flow. Use isinstance, consider abstractions like Mapping or MutableMapping, and consider avoiding type-checking altogether, using the interface directly.

You can achieve this by "interpolating" the className passed from the parent component to the child component using this.props.className. Example below:

export default class ParentComponent extends React.Component {
  render(){
    return <ChildComponent className="your-modifier-class" />
  }
}

export default class ChildComponent extends React.Component {
  render(){
    return <div className={"original-class " + this.props.className}></div>
  }
}

Adding my own experience for those who are experiencing this in the future. My specific error was

Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known'

It turns out that this was actually because I had reach the maximum number of open files on my system. It had nothing to do with failed connections, or even a DNS error as indicated.

I'm using rc.4 and this method works for ES2015(ES6):

import {DomSanitizationService} from '@angular/platform-browser';

@Component({
  templateUrl: 'build/pages/veeu/veeu.html'
})
export class VeeUPage {
  static get parameters() {
    return [NavController, App, MenuController, DomSanitizationService];
  }

  constructor(nav, app, menu, sanitizer) {

    this.app = app;
    this.nav = nav;
    this.menu = menu;
    this.sanitizer = sanitizer;    
  }

  photoURL() {
    return this.sanitizer.bypassSecurityTrustUrl(this.mediaItems[1].url);
  }
}

In the HTML:

<iframe [src]='photoURL()' width="640" height="360" frameborder="0"
    webkitallowfullscreen mozallowfullscreen allowfullscreen>
</iframe>

Using a function will ensure that the value doesn't change after you sanitize it. Also be aware that the sanitization function you use depends on the context.

For images, bypassSecurityTrustUrl will work but for other uses you need to refer to the documentation:

https://angular.io/docs/ts/latest/api/platform-browser/index/DomSanitizer-class.html

If you want to measure code efficiency, or in any other way measure time intervals, the following will be easier:

#include <time.h>

int main()
{
   clock_t start = clock();
   //... do work here
   clock_t end = clock();
   double time_elapsed_in_seconds = (end - start)/(double)CLOCKS_PER_SEC;
   return 0;
}

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

this is my solution:

    public Bitmap Blend(Bitmap topImage1, Bitmap bottomImage1, PorterDuff.Mode Type) {

        Bitmap workingBitmap = Bitmap.createBitmap(topImage1);
        Bitmap topImage = workingBitmap.copy(Bitmap.Config.ARGB_8888, true);

        Bitmap workingBitmap2 = Bitmap.createBitmap(bottomImage1);
        Bitmap bottomImage = workingBitmap2.copy(Bitmap.Config.ARGB_8888, true);

        Rect dest = new Rect(0, 0, bottomImage.getWidth(), bottomImage.getHeight());
        new BitmapFactory.Options().inPreferredConfig = Bitmap.Config.ARGB_8888;
        bottomImage.setHasAlpha(true);
        Canvas canvas = new Canvas(bottomImage);
        Paint paint = new Paint();

        paint.setXfermode(new PorterDuffXfermode(Type));

        paint.setFilterBitmap(true);
        canvas.drawBitmap(topImage, null, dest, paint);
        return bottomImage;
    }

usage :

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.SCREEN));

or

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.OVERLAY));

and the results :

Overlay mode :

Screen mode:

You can iterate DataTable like this:

private void button1_Click(object sender, EventArgs e)
{
    for(int i = 0; i< dt.Rows.Count;i++)
        for (int j = 0; j <dt.Columns.Count ; j++)
        {
            object o = dt.Rows[i].ItemArray[j];
            //if you want to get the string
            //string s = o = dt.Rows[i].ItemArray[j].ToString();
        }
}

Depending on the type of the data in the DataTable cell, you can cast the object to whatever you want.

Triggers cannot modify the changed data (Inserted or Deleted) otherwise you could get infinite recursion as the changes invoked the trigger again. One option would be for the trigger to roll back the transaction.

Edit: The reason for this is that the standard for SQL is that inserted and deleted rows cannot be modified by the trigger. The underlying reason for is that the modifications could cause infinite recursion. In the general case, this evaluation could involve multiple triggers in a mutually recursive cascade. Having a system intelligently decide whether to allow such updates is computationally intractable, essentially a variation on the halting problem.

The accepted solution to this is not to permit the trigger to alter the changing data, although it can roll back the transaction.

create table Foo (
       FooID int
      ,SomeField varchar (10)
)
go

create trigger FooInsert
    on Foo after insert as
    begin
        delete inserted
         where isnumeric (SomeField) = 1
    end
go


Msg 286, Level 16, State 1, Procedure FooInsert, Line 5
The logical tables INSERTED and DELETED cannot be updated.

Something like this will roll back the transaction.

create table Foo (
       FooID int
      ,SomeField varchar (10)
)
go

create trigger FooInsert
    on Foo for insert as
    if exists (
       select 1
         from inserted 
        where isnumeric (SomeField) = 1) begin
              rollback transaction
    end
go

insert Foo values (1, '1')

Msg 3609, Level 16, State 1, Line 1
The transaction ended in the trigger. The batch has been aborted.

Use the pattern . to match any character once, .* to match any character zero or more times, .+ to match any character one or more times.

Late to the party, but here's some simple javascript-only code to scroll any element to the bottom:

function scrollToBottom(e) {
  e.scrollTop = e.scrollHeight - e.getBoundingClientRect().height;
}

If you can use jQuery, and I highly recommend you do, you would simply do

$('#myTextArea').val('');

Otherwise, it is browser dependent. Assuming you have

var myTextArea = document.getElementById('myTextArea');

In most browsers you do

myTextArea.innerHTML = '';

But in Firefox, you do

myTextArea.innerText = '';

Figuring out what browser the user is using is left as an exercise for the reader. Unless you use jQuery, of course ;)

Edit: I take that back. Looks like support for .innerHTML on textarea's has improved. I tested in Chrome, Firefox and Internet Explorer, all of them cleared the textarea correctly.

Edit 2: And I just checked, if you use .val('') in jQuery, it just sets the .value property for textarea's. So .value should be fine.

If you want to create a simple hyperlink instead of the pin it button,

Change this:

http://pinterest.com/pin/create/button/?url=

To this:

http://pinterest.com/pin/create/link/?url=

So, a complete URL might simply look like this:

<a href="//pinterest.com/pin/create/link/?url=http%3A%2F%2Fwww.flickr.com%2Fphotos%2Fkentbrew%2F6851755809%2F&media=http%3A%2F%2Ffarm8.staticflickr.com%2F7027%2F6851755809_df5b2051c9_z.jpg&description=Next%20stop%3A%20Pinterest">Pin it</a>

Several connectors are configured, and each connector has an optional "address" attribute where you can set the IP address.

1. Edit tomcat/conf/server.xml.
2. Specify a bind address for that connector:

   <Connector 
       port="8080" 
       protocol="HTTP/1.1" 
       address="127.0.0.1"
       connectionTimeout="20000"

One approach would be to create a non-constrained (no unique indexes) table to insert all your data into and do a select distinct from that to do your insert into your hundred table.

So high level would be. I assume all three columns are distinct in my example so for step3 change the NOT EXITS join to only join on the unique columns in the hundred table.

1. Create temporary table. See docs here.

   CREATE TEMPORARY TABLE temp_data(name, name_slug, status);
   

2. INSERT Data into temp table.

   INSERT INTO temp_data(name, name_slug, status); 
   

3. Add any indexes to the temp table.

4. Do main table insert.

   INSERT INTO hundred(name, name_slug, status) 
       SELECT DISTINCT name, name_slug, status
       FROM hundred
       WHERE NOT EXISTS (
           SELECT 'X' 
           FROM temp_data
           WHERE 
               temp_data.name          = hundred.name
               AND temp_data.name_slug = hundred.name_slug
               AND temp_data.status    = status
       );
   

If you don't use conda, just use :

pip install openpyxl

If you use conda, I'd recommend :

conda install -c anaconda openpyxl

instead of simply conda install openpyxl

Because there are issues right now with conda updating (see GitHub Issue #8842) ; this is being fixed and it should work again after the next release (conda 4.7.6)

The above process is slow,you can use below method but you need to move collection by collection to another db.

use admin
db.runCommand({renameCollection: "[db_old_name].[collection_name]", to: "[db_new_name].[collection_name]"})

Using MFC it is possible with the following

CFileStatus FileStatus;
BOOL bFileExists = CFile::GetStatus(FileName,FileStatus);

Where FileName is a string representing the file you are checking for existance

Java doesn't have goto, because it makes the code unstructured and unclear to read. However, you can use break and continue as civilized form of goto without its problems.

Jumping forward using break -

ahead: {
    System.out.println("Before break");
    break ahead;
    System.out.println("After Break"); // This won't execute
}
// After a line break ahead, the code flow starts from here, after the ahead block
System.out.println("After ahead");

Output:

Before Break
After ahead

Jumping backward using continue

before: {
    System.out.println("Continue");
    continue before;
}

This will result in an infinite loop as every time the line continue before is executed, the code flow will start again from before.

UPLOAD FILES

<input type="file" name="resume" onchange="angular.element(this).scope().uploadResume()" ng-model="fileupload" id="resume" />


        $scope.uploadResume = function () { 
            var f = document.getElementById('resume').files[0];
            $scope.selectedResumeName = f.name;
            $scope.selectedResumeType = f.type;
            r = new FileReader();

            r.onloadend = function (e) { 
                $scope.data = e.target.result;
            }

            r.readAsDataURL(f);

        };

DOWNLOAD FILES:

          <a href="{{applicant.resume}}" download> download resume</a>

var app = angular.module("myApp", []);

            app.config(['$compileProvider', function ($compileProvider) {
                $compileProvider.aHrefSanitizationWhitelist(/^\s*(https?|local|data|chrome-extension):/);
                $compileProvider.imgSrcSanitizationWhitelist(/^\s*(https?|local|data|chrome-extension):/);

            }]);

When you open a folder in VSCode, it will automatically scan the folder for typical project artifacts like project.json or solution files. From the status bar in the lower left side you can switch between solutions and projects.

While yourTextField.requestFocus() is A solution, it is not the best since in the official Java documentation this is discourage as the method requestFocus() is platform dependent.

The documentation says:

Note that the use of this method is discouraged because its behavior is platform dependent. Instead we recommend the use of requestFocusInWindow().

Use yourJTextField.requestFocusInWindow() instead.

Also possible with vanilla JS

new Date().toISOString() // "2017-08-26T16:31:02.349Z"

In my case:

sudo -E add-apt-repository ppa:linuxuprising/java

sudo apt-get update

sudo apt install  oracle-java12-installer

that works fine

I think this is the culprit:

cmd = new SqlCommand(query, con);

DataTable dt = Select(query);

cmd.ExecuteNonQuery();

ddtype.DataSource = dt;

I don't know what that code is supposed to do, but it looks like you want to create an SqlDataReader for that, as explained here and all over the web if you search for "SqlCommand DropDownList DataSource":

cmd = new SqlCommand(query, con);
ddtype.DataSource = cmd.ExecuteReader();

Or you can create a DataTable as explained here:

cmd = new SqlCommand(query, con);

SqlDataAdapter listQueryAdapter = new SqlDataAdapter(cmd);
DataTable listTable = new DataTable();
listQueryAdapter.Fill(listTable);

ddtype.DataSource = listTable;

Most likely it means that the open didn't fail.

When Perl opens a file, it checks whether or not the file is a TTY (so that it can answer the -T $fh filetest operator) by issuing the TCGETS ioctl against it. If the file is a regular file and not a tty, the ioctl fails and sets errno to ENOTTY (string value: "Inappropriate ioctl for device"). As ysth says, the most common reason for seeing an unexpected value in $! is checking it when it's not valid -- that is, anywhere other than immediately after a syscall failed, so testing the result codes of your operations is critically important.

If open actually did return false for you, and you found ENOTTY in $! then I would consider this a small bug (giving a useless value of $!) but I would also be very curious as to how it happened. Code and/or truss output would be nifty.

Now, with EF Core you can convert data type transparently in your AppDbContext

protected override void OnModelCreating(ModelBuilder modelBuilder)
{
      // i.e. Store TimeSpan as string (custom)
      modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(
            timeSpan => timeSpan.ToString(), // To DB
            timeSpanString => TimeSpan.Parse(timeSpanString) // From DB
        );

    // i.e. Store TimeSpan as string (using TimeSpanToStringConverter)
    modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(new TimeSpanToStringConverter());

      // i.e. Store TimeSpan as number of ticks (custom)
      modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(
            timeSpan => timeSpan.Ticks, // To DB
            timeSpanString => TimeSpan.FromTicks(timeSpanString) // From DB
        );

    // i.e. Store TimeSpan as number of ticks (using TimeSpanToTicksConverter)
    modelBuilder
        .Entity<YourClass>()
        .Property(x => x.YourTimeSpan)
        .HasConversion(new TimeSpanToTicksConverter());
}

try using IP instead of pc name. If the ip working, then it might be the name pipe is not enable. If it;s still not working then the login using windows might be disabled.

As @Raheel Answered it will fine but if you are working with Laravel 7/6

Then Eloquent whereIn Query.

Example1:

$users = User::wherein('id',[1,2,3])->get();

Example2:

$users = DB::table('users')->whereIn('id', [1, 2, 3])->get();

Example3:

$ids = [1,2,3];

$users = User::wherein('id',$ids)->get();

An HTML parser should be used for this purpose rather than regular expressions. A Perl program that makes use of HTML::TreeBuilder:

Program

#!/usr/bin/env perl

use strict;
use warnings;

use HTML::TreeBuilder;

my $tree = HTML::TreeBuilder->new_from_file( \*DATA );
my @elements = $tree->look_down(
    sub { defined $_[0]->attr('name') }
);

for (@elements) {
    print $_->attr('name'), "\n";
}

__DATA__
<table name="content_analyzer" primary-key="id">
  <type="global" />
</table>
<table name="content_analyzer2" primary-key="id">
  <type="global" />
</table>
<table name="content_analyzer_items" primary-key="id">
  <type="global" />
</table>

Output

content_analyzer
content_analyzer2
content_analyzer_items

Here is my Solution, I think will better to use vh (viewport height) and vw for (viewport width), units regarding to the height and width of the current viewport

function myFunction() {
  var element = document.getElementById("main");
  element.classList.add("container");
}

.container{
  height: 100vh;
  width: 100vw;
  overflow: hidden;
  background-color: #333;
  margin: 0; 
  padding: 0; 
}

<div id="main"></div>
<button onclick="myFunction()">Try it</button>

An alternative solution is to store the keys in a separate Collection:

'Initialise these somewhere.
Dim Keys As Collection, Values As Collection

'Add types for K and V as necessary.
Sub Add(K, V) 
Keys.Add K
Values.Add V, K
End Sub

You can maintain a separate sort order for the keys and the values, which can be useful sometimes.

I am a newbie to svn version control. However, for the case when people want to add files without ignoring the already set svn:ignore properties, I solved the issue as below

1. svn add --depth empty path/to/directory
2. Execute "svn propset svn:ignore -F ignoreList.txt --recursive" from the location where the ignoreList.txt resides. In my case this file was residing two directories above the "path/to/directory", which I wanted to add. Note that ignoreList.txt contains the file extensions I want svn to ignore, e.g. *.aux etc.
3. svn add --force path/to/directory/.

The above steps worked.

This is an adapted version of the answer given by Vivien Barousse with the update from Vulcan applied. In this example I use sliders to dynamically retreive the RGB values from three sliders and display that color in a rectangle. Then in method toHex() I use the values to create a color and display the respective Hex color code.

This example does not include the proper constraints for the GridBagLayout. Though the code will work, the display will look strange.

public class HexColor
{

  public static void main (String[] args)
  {
   JSlider sRed = new JSlider(0,255,1);
   JSlider sGreen = new JSlider(0,255,1);
   JSlider sBlue = new JSlider(0,255,1);
   JLabel hexCode = new JLabel();
   JPanel myPanel = new JPanel();
   GridBagLayout layout = new GridBagLayout();
   JFrame frame = new JFrame();

   //set frame to organize components using GridBagLayout 
   frame.setLayout(layout);

   //create gray filled rectangle 
   myPanel.paintComponent();
   myPanel.setBackground(Color.GRAY);

   //In practice this code is replicated and applied to sGreen and sBlue. 
   //For the sake of brevity I only show sRed in this post.
   sRed.addChangeListener(
         new ChangeListener()
         {
             @Override
             public void stateChanged(ChangeEvent e){
                 myPanel.setBackground(changeColor());
                 myPanel.repaint();
                 hexCode.setText(toHex());
         }
         }
     );
   //add each component to JFrame
   frame.add(myPanel);
   frame.add(sRed);
   frame.add(sGreen);
   frame.add(sBlue);
   frame.add(hexCode);
} //end of main

  //creates JPanel filled rectangle
  protected void paintComponent(Graphics g)
  {
      super.paintComponent(g);
      g.drawRect(360, 300, 10, 10);
      g.fillRect(360, 300, 10, 10);
  }

  //changes the display color in JPanel
  private Color changeColor()
  {
    int r = sRed.getValue();
    int b = sBlue.getValue();
    int g = sGreen.getValue();
    Color c;
    return  c = new Color(r,g,b);
  }

  //Displays hex representation of displayed color
  private String toHex()
  {
      Integer r = sRed.getValue();
      Integer g = sGreen.getValue();
      Integer b = sBlue.getValue();
      Color hC;
      hC = new Color(r,g,b);
      String hex = Integer.toHexString(hC.getRGB() & 0xffffff);
      while(hex.length() < 6){
          hex = "0" + hex;
      }
      hex = "Hex Code: #" + hex;
      return hex;
  }
}

A huge thank you to both Vivien and Vulcan. This solution works perfectly and was super simple to implement.

Just add those as said above:

    android:singleLine="true" 
    android:ellipsize="marquee"
    android:marqueeRepeatLimit ="marquee_forever"

AND!! you must use TextView.setSelected(true) inside your java code.

The reason for marquee not working with some of the guys in this article , If you have an input form with an EditText ( which is an input), The EditText will be the one with focus and selection by default in the form. Now, if you force it thru TextView.setSelected(true), TextView will eventually do marquee no matter what.

So the whole idea is to make the TextView widget focused and selected to make marquee work.

MixEdit extension for Visual Studio allows you to do multiediting in the way you are describing. It supports multiple carets and multiple selections.

It will work like charm take a look at the demo.

window.alert = null;
alert('test'); // fail
delete window.alert; // true
alert('test'); // win

window is an instance of DOMWindow, and by setting something to window.alert, the correct implementation is being "shadowed", i.e. when accessing alert it is first looking for it on the window object. Usually this is not found, and it then goes up the prototype chain to find the native implementation. However, when manually adding the alert property to window it finds it straight away and does not need to go up the prototype chain. Using delete window.alert you can remove the window own property and again expose the prototype implementation of alert. This may help explain:

window.hasOwnProperty('alert'); // false
window.alert = null;
window.hasOwnProperty('alert'); // true
delete window.alert;
window.hasOwnProperty('alert'); // false

You can try more system indeppended method: system("pause");

Background image is not Set Perfect then his css is problem create so his css file change to below code

html {  _x000D_
  background-image: url("example.png");  _x000D_
  background-repeat: no-repeat;  _x000D_
  background-position: 0% 0%;_x000D_
  background-size: 100% 100%;_x000D_
}

%; background-size: 100% 100%;"

This is very simple in LinQ... You can use the select statement to get an Enumerable of properties of the objects.

var mySkus = myLines.Select(x => x.Sku);

Or if you want it as an Array just do...

var mySkus = myLines.Select(x => x.Sku).ToArray();

You must to change & to %26 in query string from your url

Look at this: https://dev.twitter.com/discussions/8616

You can access documents directory using this code it is basically used for storing file in plist format:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths firstObject];
return documentsDirectory;

In Posgresql you could use ~

For example you could search for all rows that have col_a with any letter in lowercase

select * from your_table where col_a '[a-z]';

You could modify the Regex expression according your needs.

Regards,

This only works for languages with are not whitespace delineated, but my solution is to remove all whitespace except for spaces, then add a newline after characters that usually delineate EOL (e.g. replace ';' with ';\n') then do the ubiquitous ^+i solution.

I use Python.

Example code, just replace the filenames:

python -c "import re; open(outfile,'w').write(re.sub('[\t\n\r]','',open(infile).read()).replace(';',';\n').replace('{','{\n').replace('}','}\n'))"

It 's not perfect (Example: for loops), but I like it.

Install:

gacutil -i "path_to_the_assembly"

View:

Open in Windows Explorer folder

• .NET 1.0 - NET 3.5: c:\windows\assembly (%systemroot%\assembly)
• .NET 4.x: %windir%\Microsoft.NET\assembly

OR gacutil –l

When you are going to install an assembly you have to specify where gacutil can find it, so you have to provide a full path as well. But when an assembly already is in GAC - gacutil know a folder path so it just need an assembly name.

MSDN:

• How to: Install an Assembly into the Global Assembly Cache

$sql = "INSERT INTO table_name( field1, field2 )  VALUES ('foo','bar') 
        RETURNING ID INTO :mylastid";
$stmt = oci_parse($db, $sql);
oci_bind_by_name($stmt, "mylastid", $last_id, 8, SQLT_INT);
oci_execute($stmt);

echo "last inserted id is:".$last_id;

Tip: you have to use your id column name in {your_id_col_name} below...

"RETURNING {your_id_col_name} INTO :mylastid"

It may also happen in the following case:

eg. if we consider the push function of a stack:

typedef struct stack
{
    int a[20];
    int head;
}stack;

void push(stack **s)
{
    int data;
    printf("Enter data:");
    scanf("%d",&(*s->a[++*s->head])); /* this is where the error is*/
}

main()
{
    stack *s;
    s=(stack *)calloc(1,sizeof(stack));
    s->head=-1;
    push(&s);
    return 0;
}

The error is in the push function and in the commented line. The pointer s has to be included within the parentheses. The correct code:

scanf("%d",&( (*s)->a[++(*s)->head]));

Salvete! I needed, simply, a function I could call to make the code wait for the page to load before it continued. After scouring the web for answers, and fiddling around for several hours, I came up with this to solve for myself, the exact dilemma you present. I know I am late in the game with an answer, but I wish to post this for anyone else who comes along.

usage: just call WaitForPageLoad() just after a call to navigation:

whatbrowser.Navigate("http://www.google.com")
WaitForPageLoad()

another example we don't combine the navigate feature with the page load, because sometimes you need to wait for a load without also navigating, for example, you might need to wait for a page to load that was started with an invokemember event:

whatbrowser.Document.GetElementById("UserName").InnerText = whatusername
whatbrowser.Document.GetElementById("Password").InnerText = whatpassword
whatbrowser.Document.GetElementById("LoginButton").InvokeMember("click")
WaitForPageLoad()

Here is the code: You need both subs plus the accessible variable, pageready. First, make sure to fix the variable called whatbrowser to be your webbrowser control

Now, somewhere in your module or class, place this:

Private Property pageready As Boolean = False

#Region "Page Loading Functions"
    Private Sub WaitForPageLoad()
        AddHandler whatbrowser.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf PageWaiter)
        While Not pageready
            Application.DoEvents()
        End While
        pageready = False
    End Sub

    Private Sub PageWaiter(ByVal sender As Object, ByVal e As WebBrowserDocumentCompletedEventArgs)
        If whatbrowser.ReadyState = WebBrowserReadyState.Complete Then
            pageready = True
            RemoveHandler whatbrowser.DocumentCompleted, New WebBrowserDocumentCompletedEventHandler(AddressOf PageWaiter)
        End If
    End Sub

#End Region

Use of Ascyimageview you can easy load imageurl in imageview.

let image1Url:URL = URL(string: "(imageurl)" as String)! imageview.imageURL = image1Url

In my case (Spring MVC + Hibernate project), I added Controller, Service, Dao, Model class & Thyme leaf page. Just didn't map new model class in "hibernate.cfg.xml" file. So that got this error. But after mapping new model class again got the error. Then deleted Controller, Service, Dao, Model class. Thyme leaf page and Created newly. Also mapped new model class. Then error has gone.

I handled it by first making a list of all the fragments (List<Fragment> fragments;) that I was going to use then added them to the pager making it easier to handle the currently viewed fragment.

So:

@Override
onCreate(){
    //initialise the list of fragments
    fragments = new Vector<Fragment>();

    //fill up the list with out fragments
    fragments.add(Fragment.instantiate(this, MainFragment.class.getName()));
    fragments.add(Fragment.instantiate(this, MenuFragment.class.getName()));
    fragments.add(Fragment.instantiate(this, StoresFragment.class.getName()));
    fragments.add(Fragment.instantiate(this, AboutFragment.class.getName()));
    fragments.add(Fragment.instantiate(this, ContactFragment.class.getName()));


    //Set up the pager
    pager = (ViewPager)findViewById(R.id.pager);
    pager.setAdapter(new MyFragmentPagerAdapter(getSupportFragmentManager(), fragments));
    pager.setOffscreenPageLimit(4);
}

so then this can be called:

public Fragment getFragment(ViewPager pager){   
    Fragment theFragment = fragments.get(pager.getCurrentItem());
    return theFragment;
}

so then i could chuck it in an if statement that would only run if it was on the correct fragment

Fragment tempFragment = getFragment();
if(tempFragment == MyFragmentNo2.class){
    MyFragmentNo2 theFrag = (MyFragmentNo2) tempFragment;
    //then you can do whatever with the fragment
    theFrag.costomFunction();
}

but thats just my hack and slash approach but it worked for me, I use it do do relevent changes to my currently displayed fragment when the back button is pushed.

You can use the Unix-style -l switch – typically terse and cryptic – or the equivalent --files-with-matches – longer and more readable.

The output of grep --help is not easy to read, but it's there:

-l, --files-with-matches  print only names of FILEs containing matches

Try this:

$str = htmlentities($str,ENT_QUOTES,'UTF-8');

So, after filtering your data using htmlentities() function, you can use the data in XML tag like:

<mytag>$str</mytag>

For the Spring Tool Suit (Extension of Eclipse), in Windows is

Alt + Shift + Q, C

The key is calling the parent's method using super.methodName();

class A {
    // A protected method
    protected doStuff()
    {
        alert("Called from A");
    }

    // Expose the protected method as a public function
    public callDoStuff()
    {
        this.doStuff();
    }
}

class B extends A {

    // Override the protected method
    protected doStuff()
    {
        // If we want we can still explicitly call the initial method
        super.doStuff();
        alert("Called from B");
    }
}

var a = new A();
a.callDoStuff(); // Will only alert "Called from A"

var b = new B()
b.callDoStuff(); // Will alert "Called from A" then "Called from B"

Try it here

>>> for i in range(1, 11):
...     print(i, end=' ')
...     if i==len(range(1, 11)): print()
... 
1 2 3 4 5 6 7 8 9 10 
>>> 

This is how to do it so that the printing does not run behind the prompt on the next line.

The const variable specifies whether a variable is modifiable or not. The constant value assigned will be used each time the variable is referenced. The value assigned cannot be modified during program execution.

Bjarne Stroustrup's explanation sums it up briefly:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects.

A const variable has to be declared within the class, but it cannot be defined in it. We need to define the const variable outside the class.

T1() : t( 100 ){}

Here the assignment t = 100 happens in initializer list, much before the class initilization occurs.

If you use git config user.email "[email protected]" it will be bound to the current project you are in.

That is what I do for my projects. I set the appropriate identity when I clone/init the repo. It is not fool-proof (if you forget and push before you figure it out you are hosed) but it is about as good as you can get without the ability to say git config --global user.email 'ILLEGAL_VALUE'

Actually, you can make an illegal value. Set your git config --global user.name $(perl -e 'print "x"x968;')

Then if you forget to set your non-global values you will get an error message.

[EDIT] On a different system I had to increase the number of x to 968 to get it to fail with "fatal: Impossibly long personal identifier". Same version of git. Strange.

Let's say we have a single byte:

0110110

Applying a single left bitshift gets us:

1101100

The leftmost zero was shifted out of the byte, and a new zero was appended to the right end of the byte.

The bits don't rollover; they are discarded. That means if you left shift 1101100 and then right shift it, you won't get the same result back.

Shifting left by N is equivalent to multiplying by 2^N.

Shifting right by N is (if you are using ones' complement) is the equivalent of dividing by 2^N and rounding to zero.

Bitshifting can be used for insanely fast multiplication and division, provided you are working with a power of 2. Almost all low-level graphics routines use bitshifting.

For example, way back in the olden days, we used mode 13h (320x200 256 colors) for games. In Mode 13h, the video memory was laid out sequentially per pixel. That meant to calculate the location for a pixel, you would use the following math:

memoryOffset = (row * 320) + column

Now, back in that day and age, speed was critical, so we would use bitshifts to do this operation.

However, 320 is not a power of two, so to get around this we have to find out what is a power of two that added together makes 320:

(row * 320) = (row * 256) + (row * 64)

Now we can convert that into left shifts:

(row * 320) = (row << 8) + (row << 6)

For a final result of:

memoryOffset = ((row << 8) + (row << 6)) + column

Now we get the same offset as before, except instead of an expensive multiplication operation, we use the two bitshifts...in x86 it would be something like this (note, it's been forever since I've done assembly (editor's note: corrected a couple mistakes and added a 32-bit example)):

mov ax, 320; 2 cycles
mul word [row]; 22 CPU Cycles
mov di,ax; 2 cycles
add di, [column]; 2 cycles
; di = [row]*320 + [column]

; 16-bit addressing mode limitations:
; [di] is a valid addressing mode, but [ax] isn't, otherwise we could skip the last mov

Total: 28 cycles on whatever ancient CPU had these timings.

Vrs

mov ax, [row]; 2 cycles
mov di, ax; 2
shl ax, 6;  2
shl di, 8;  2
add di, ax; 2    (320 = 256+64)
add di, [column]; 2
; di = [row]*(256+64) + [column]

12 cycles on the same ancient CPU.

Yes, we would work this hard to shave off 16 CPU cycles.

In 32 or 64-bit mode, both versions get a lot shorter and faster. Modern out-of-order execution CPUs like Intel Skylake (see http://agner.org/optimize/) have very fast hardware multiply (low latency and high throughput), so the gain is much smaller. AMD Bulldozer-family is a bit slower, especially for 64-bit multiply. On Intel CPUs, and AMD Ryzen, two shifts are slightly lower latency but more instructions than a multiply (which may lead to lower throughput):

imul edi, [row], 320    ; 3 cycle latency from [row] being ready
add  edi, [column]      ; 1 cycle latency (from [column] and edi being ready).
; edi = [row]*(256+64) + [column],  in 4 cycles from [row] being ready.

vs.

mov edi, [row]
shl edi, 6               ; row*64.   1 cycle latency
lea edi, [edi + edi*4]   ; row*(64 + 64*4).  1 cycle latency
add edi, [column]        ; 1 cycle latency from edi and [column] both being ready
; edi = [row]*(256+64) + [column],  in 3 cycles from [row] being ready.

Compilers will do this for you: See how GCC, Clang, and Microsoft Visual C++ all use shift+lea when optimizing return 320*row + col;.

The most interesting thing to note here is that x86 has a shift-and-add instruction (LEA) that can do small left shifts and add at the same time, with the performance as an add instruction. ARM is even more powerful: one operand of any instruction can be left or right shifted for free. So scaling by a compile-time-constant that's known to be a power-of-2 can be even more efficient than a multiply.

OK, back in the modern days... something more useful now would be to use bitshifting to store two 8-bit values in a 16-bit integer. For example, in C#:

// Byte1: 11110000
// Byte2: 00001111

Int16 value = ((byte)(Byte1 >> 8) | Byte2));

// value = 000011111110000;

In C++, compilers should do this for you if you used a struct with two 8-bit members, but in practice they don't always.

DATE_FORMAT returns a string, so you're using two strings in your BETWEEN clause, which isn't going to work as you expect.

Instead, convert the date to your format in the SELECT and do the BETWEEN for the actual dates. For example,

SELECT DATE_FORMAT(create_date, '%m/%d/%y') as create_date_formatted
FROM table
WHERE create_date BETWEEN (CURDATE() - INTERVAL 30 DAY) AND CURDATE()

Once you have IIS Express installed (the easiest way is through Microsoft Web Platform Installer), you will find the executable file in %PROGRAMFILES%\IIS Express (%PROGRAMFILES(x86)%\IIS Express on x64 architectures) and its called iisexpress.exe.

To see all the possible command-line options, just run:

iisexpress /?

and the program detailed help will show up.

If executed without parameters, all the sites defined in the configuration file and marked to run at startup will be launched. An icon in the system tray will show which sites are running.

There are a couple of useful options once you have some sites created in the configuration file (found in %USERPROFILE%\Documents\IISExpress\config\applicationhost.config): the /site and /siteId.

With the first one, you can launch a specific site by name:

iisexpress /site:SiteName

And with the latter, you can launch by specifying the ID:

iisexpress /siteId:SiteId

With this, if IISExpress is launched from the command-line, a list of all the requests made to the server will be shown, which can be quite useful when debugging.

Finally, a site can be launched by specifying the full directory path. IIS Express will create a virtual configuration file and launch the site (remember to quote the path if it contains spaces):

iisexpress /path:FullSitePath

This covers the basic IISExpress usage from the command line.

Use the Out-File cmdlet

 Compare-Object ... | Out-File C:\filename.txt

Optionally, add -Encoding utf8 to Out-File as the default encoding is not really ideal for many uses.

this question seem quite old but incase you come pass it, you can use the PHP inbuilt function array_push() to push data in an array using the example below.

<?php
    $item = array();
    foreach($group_membership as $i => $username) {
        array_push($item, $username);
    }
    print_r($items);
?>

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

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

str.replace(/\s/g,'')

Works for me.

jQuery.trim has the following hack for IE, although I'm not sure what versions it affects:

// Check if a string has a non-whitespace character in it
rnotwhite = /\S/

// IE doesn't match non-breaking spaces with \s
if ( rnotwhite.test( "\xA0" ) ) {
    trimLeft = /^[\s\xA0]+/;
    trimRight = /[\s\xA0]+$/;
}

For me, I had things unnecessarily split into separate folders. I'm running plotly dash and I had my Procfile, and Pipfile (and lock) together, but separate from the other features of my app (run.py and app.py, the actual content of the pages being used was in a subfolder). So joining much of that together repaired my H10 error

as simple as:

tmpHM.each{ key, value -> 
  doSomethingWithKeyAndValue key, value
}

to remove the border , juste using css like this :

td {
 border-style : hidden!important;
}

If you are using Ubuntu.

sudo chown -R www-data:www-data PATH_TO_YOUR_WORDPRESS_FOLDER

Here are three different ways to do it:

Here's a working Demo in Fiddle Of All Three

Validation:

You can use native bootstrap validation states (No Custom CSS!):

<div class="form-group has-feedback">
    <label class="control-label" for="inputSuccess2">Name</label>
    <input type="text" class="form-control" id="inputSuccess2"/>
    <span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>

For a full discussion, see my answer to Add a Bootstrap Glyphicon to Input Box

Input Group:

You can use the .input-group class like this:

<div class="input-group">
    <input type="text" class="form-control"/>
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

For a full discussion, see my answer to adding Twitter Bootstrap icon to Input box

Unstyled Input Group:

You can still use .input-group for positioning but just override the default styling to make the two elements appear separate.

Use a normal input group but add the class input-group-unstyled:

<div class="input-group input-group-unstyled">
    <input type="text" class="form-control" />
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

Then change the styling with the following css:

.input-group.input-group-unstyled input.form-control {
    -webkit-border-radius: 4px;
       -moz-border-radius: 4px;
            border-radius: 4px;
}
.input-group-unstyled .input-group-addon {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

Also, these solutions work for any input size

I struggled for ages on this one before I realized my error - I had used commas instead of semicolons in the connect string

Here's another way to process command line args, using R CMD BATCH. My approach, which builds on an earlier answer here, lets you specify arguments at the command line and, in your R script, give some or all of them default values.

Here's an R file, which I name test.R:

defaults <- list(a=1, b=c(1,1,1)) ## default values of any arguments we might pass

## parse each command arg, loading it into global environment
for (arg in commandArgs(TRUE))
  eval(parse(text=arg))

## if any variable named in defaults doesn't exist, then create it
## with value from defaults
for (nm in names(defaults))
  assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]))[[1]])

print(a)
print(b)

At the command line, if I type

R CMD BATCH --no-save --no-restore '--args a=2 b=c(2,5,6)' test.R

then within R we'll have a = 2 and b = c(2,5,6). But I could, say, omit b, and add in another argument c:

R CMD BATCH --no-save --no-restore '--args a=2 c="hello"' test.R

Then in R we'll have a = 2, b = c(1,1,1) (the default), and c = "hello".

Finally, for convenience we can wrap the R code in a function, as long as we're careful about the environment:

## defaults should be either NULL or a named list
parseCommandArgs <- function(defaults=NULL, envir=globalenv()) {
  for (arg in commandArgs(TRUE))
    eval(parse(text=arg), envir=envir)

  for (nm in names(defaults))
    assign(nm, mget(nm, ifnotfound=list(defaults[[nm]]), envir=envir)[[1]], pos=envir)
}

## example usage:
parseCommandArgs(list(a=1, b=c(1,1,1)))

As an alternative to the chosen answer, and with the same safe semantics of Marcel's, here is a compact way of using a Python dictionary to specify the values. It has the benefit of being easy to modify as you add or remove columns to insert:

  meta_cols=('SongName','SongArtist','SongAlbum','SongGenre')
  insert='insert into Songs ({0}) values ({1})'.
        .format(','.join(meta_cols), ','.join( ['%s']*len(meta_cols) ))
  args = [ meta[i] for i in meta_cols ]
  cursor=db.cursor()
  cursor.execute(insert,args)
  db.commit()

Where meta is the dictionary holding the values to insert. Update can be done in the same way:

  meta_cols=('SongName','SongArtist','SongAlbum','SongGenre')
  update='update Songs set {0} where id=%s'.
        .format(','.join([ '{0}=%s'.format(c) for c in meta_cols ]))
  args = [ meta[i] for i in meta_cols ]
  args.append( songid )
  cursor=db.cursor()
  cursor.execute(update,args)
  db.commit()

I tried every single thing on this page (and thanks everyone!). Nothing worked. After literally hours and hours, I finally got it working.

My problem was that I had no error preceding "something went wrong in step ´Checking status on default´".

This line in the start.sh script failed.

VM_STATUS="$( set +e ; "${DOCKER_MACHINE}" status "${VM}" )"

Running the following line from the Command Prompt worked and returned "Running".

D:\Dev\DockerToolbox\docker-machine.exe status default

So I started following all the fixes in Github link and found the fix.

In the start.sh script, I changed the line

VM_STATUS="$( set +e ; "${DOCKER_MACHINE}" status "${VM}" )"

to

VM_STATUS="$(${DOCKER_MACHINE} status ${VM})"

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

I used the following with Twitter Bootstrap (v3)

<footer id="colophon" style="position: fixed; bottom: 0px; width: 100%;">
    <div class="container">
        <p>Stuff - rows - cols etc</p>
    </div>
</footer>

I.e make a full width element that is fixed position, and just shove a container in it, the container is centered relative to the full width. Should behave ok responsively too.

Try this:

<a onclick='$("#notification").fadeOut(300, function() { $(this).remove(); });' class="notificationClose "><img src="close.png"/></a>

I think your double quotes around the onclick were making it not work. :)

EDIT: As pointed out below, inline javascript is evil and you should probably take this out of the onclick and move it to jQuery's click() event handler. That is how the cool kids are doing it nowadays.

The question is what do you want the div's height/width to be a percent of?

By default, if you assign a percentage value to a height/width it will be relative to it's direct parent dimensions. If the parent doesn't have a defined height, then it won't work.

So simply, remember to set the height of the parent, then a percentage height will work via the css attribute:

obj.style.width = '50%';

Very Simple way to create an object in Java using Class<?> with constructor argument(s) passing:

Case 1:- Here, is a small code in this Main class:

import java.lang.reflect.Constructor;
import java.lang.reflect.InvocationTargetException;

public class Main {

    public static void main(String args[]) throws ClassNotFoundException, NoSuchMethodException, SecurityException, InstantiationException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {

        // Get class name as string.
        String myClassName = Base.class.getName();
        // Create class of type Base.
        Class<?> myClass = Class.forName(myClassName);
        // Create constructor call with argument types.
        Constructor<?> ctr = myClass.getConstructor(String.class);
        // Finally create object of type Base and pass data to constructor.
        String arg1 = "My User Data";
        Object object = ctr.newInstance(new Object[] { arg1 });
        // Type-cast and access the data from class Base.
        Base base = (Base)object;
        System.out.println(base.data);
    }

}

And, here is the Base class structure:

public class Base {

    public String data = null;

    public Base() 
    {
        data = "default";
        System.out.println("Base()");
    }

    public Base(String arg1) {
        data = arg1;
        System.out.println("Base("+arg1+")");
    }

}

Case 2:- You, can code similarly for constructor with multiple argument and copy constructor. For example, passing 3 arguments as parameter to the Base constructor will need the constructor to be created in class and a code change in above as:

Constructor<?> ctr = myClass.getConstructor(String.class, String.class, String.class);
Object object = ctr.newInstance(new Object[] { "Arg1", "Arg2", "Arg3" }); 

And here the Base class should somehow look like:

public class Base {

    public Base(String a, String b, String c){
        // This constructor need to be created in this case.
    }   
}

Note:- Don't forget to handle the various exceptions which need to be handled in the code.

Explaining how you can use cut:

cat yourxmlfile | cut -d'"' -f2

It will 'cut' all the lines in the file based on " delimiter, and will take the 2nd field , which is what you wanted.

In my case, I was on CentOS 7 and my php installation was pointing to a certificate that was being generated through update-ca-trust. The symlink was /etc/pki/tls/cert.pem pointing to /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem. This was just a test server and I wanted my self signed cert to work properly. So in my case...

# My root ca-trust folder was here. I coped the .crt file to this location
# and renamed it to a .pem
/etc/pki/ca-trust/source/anchors/self-signed-cert.pem

# Then run this command and it will regenerate the certs for you and
# include your self signed cert file.
update-ca-trust

Then some of my api calls started working as my cert was now trusted. Also if your ca-trust gets updated through yum or something, this will rebuild your root certificates and still include your self signed cert. Run man update-ca-trust for more info on what to do and how to do it. :)

Call the perl binary, in search and replace per line mode ( the -pi ) by running the perl code ( the -e) in the single quotes, which iterates over the keys of the special %ENV hash containing the exported variable names as keys and the exported variable values as the keys' values and for each iteration simple replace a string containing a $<<key>> with its <<value>>.

 perl -pi -e 'foreach $key(sort keys %ENV){ s/\$$key/$ENV{$key}/g}' file

Caveat: An additional logic handling is required for cases in which two or more vars start with the same string ...

Calling this method with in the current action ensures that all the items in TempData are not removed at the end of the current request.

    @model MyProject.Models.EmpModel;
    @{
    Layout = "~/Views/Shared/_Layout.cshtml";
    ViewBag.Title = "About";
    var tempDataEmployeet = TempData["emp"] as Employee; //need typcasting
    TempData.Keep(); // retains all strings values
    } 

void Keep(string key)

Calling this method with in the current action ensures that specific item in TempData is not removed at the end of the current request.

    @model MyProject.Models.EmpModel;
    @{
    Layout = "~/Views/Shared/_Layout.cshtml";
    ViewBag.Title = "About";
    var tempDataEmployeet = TempData["emp"] as Employee; //need typcasting
    TempData.Keep("emp"); // retains only "emp" string values
    } 

Modify to suit your specifics, or make more generic as needed:

Private Sub CopyItOver()
  Set NewBook = Workbooks.Add
  Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
  NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
  NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub

CSS transitions work by defining two states for the object using CSS. In your case, you define how the object looks when it has the class "saved" and you define how it looks when it doesn't have the class "saved" (it's normal look). When you remove the class "saved", it will transition to the other state according to the transition settings in place for the object without the "saved" class.

If the CSS transition settings apply to the object (without the "saved" class), then they will apply to both transitions.

We could help more specifically if you included all relevant CSS you're using to with the HTML you've provided.

My guess from looking at your HTML is that your transition CSS settings only apply to .saved and thus when you remove it, there are no controls to specify a CSS setting. You may want to add another class ".fade" that you leave on the object all the time and you can specify your CSS transition settings on that class so they are always in effect.

Reason #1

There was a point where buggy/lazy implementations of HTML/XHTML renderers were more common than those that got it right. Many years ago, I regularly encountered rendering problems in mainstream browsers resulting from the use of unencoded quote chars in regular text content of HTML/XHTML documents. Though the HTML spec has never disallowed use of these chars in text content, it became fairly standard practice to encode them anyway, so that non-spec-compliant browsers and other processors would handle them more gracefully. As a result, many "old-timers" may still do this reflexively. It is not incorrect, though it is now probably unnecessary, unless you're targeting some very archaic platforms.

Reason #2

When HTML content is generated dynamically, for example, by populating an HTML template with simple string values from a database, it's necessary to encode each value before embedding it in the generated content. Some common server-side languages provided a single function for this purpose, which simply encoded all chars that might be invalid in some context within an HTML document. Notably, PHP's htmlspecialchars() function is one such example. Though there are optional arguments to htmlspecialchars() that will cause it to ignore quotes, those arguments were (and are) rarely used by authors of basic template-driven systems. The result is that all "special chars" are encoded everywhere they occur in the generated HTML, without regard for the context in which they occur. Again, this is not incorrect, it's simply unnecessary.

Bootstrap 4

Create a responsive navbar sidebar "drawer" in Bootstrap 4?
Bootstrap horizontal menu collapse to sidemenu

Bootstrap 3

I think what you're looking for is generally known as an "off-canvas" layout. Here is the standard off-canvas example from the official Bootstrap docs: http://getbootstrap.com/examples/offcanvas/

The "official" example uses a right-side sidebar the toggle off and on separately from the top navbar menu. I also found these off-canvas variations that slide in from the left and may be closer to what you're looking for..

Add "new":

var movies = _db.Movies.OrderBy( m => new { m.CategoryID, m.Name })

That works on my box. It does return something that can be used to sort. It returns an object with two values.

Similar, but different to sorting by a combined column, as follows.

var movies = _db.Movies.OrderBy( m => (m.CategoryID.ToString() + m.Name))

The only reliably way I know is to use VBScript to do the heavy work for you. There is no portable way of getting the current date in a usable format with a batch file alone. The following VBScript file

Wscript.Echo("set Year=" & DatePart("yyyy", Date))
Wscript.Echo("set Month=" & DatePart("m", Date))
Wscript.Echo("set Day=" & DatePart("d", Date))

and this batch snippet

for /f "delims=" %%x in ('cscript /nologo date.vbs') do %%x
echo %Year%-%Month%-%Day%

should work, though.

While you can get the current date in a batch file with either date /t or the %date% pseudo-variable, both follow the current locale in what they display. Which means you get the date in potentially any format and you have no way of parsing that.

class Student(object):
    name = ""
    age = 0
    major = ""

    # The class "constructor" - It's actually an initializer 
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

def make_student(name, age, major):
    student = Student(name, age, major)
    return student

Note that even though one of the principles in Python's philosophy is "there should be one—and preferably only one—obvious way to do it", there are still multiple ways to do this. You can also use the two following snippets of code to take advantage of Python's dynamic capabilities:

class Student(object):
    name = ""
    age = 0
    major = ""

def make_student(name, age, major):
    student = Student()
    student.name = name
    student.age = age
    student.major = major
    # Note: I didn't need to create a variable in the class definition before doing this.
    student.gpa = float(4.0)
    return student

I prefer the former, but there are instances where the latter can be useful – one being when working with document databases like MongoDB.

import subprocess
subprocess.check_output('echo "' + YOURTEXT + '" >> hello.txt',shell=True)

You can do this simply with a function. For example:

def script():
    # program code here...
    restart = raw_input("Would you like to restart this program?")
    if restart == "yes" or restart == "y":
        script()
    if restart == "n" or restart == "no":
        print "Script terminating. Goodbye."
script()

Of course you can change a lot of things here. What is said, what the script will accept as a valid input, the variable and function names. You can simply nest the entire program in a user-defined function (Of course you must give everything inside an extra indent) and have it restart at anytime using this line of code: myfunctionname(). More on this here.

There are many options to change the font size in the Visual studio code(version:1.36.1), Editor

Option 1:

Go To: File > Preferences > Settings > select User tab > Text Editor > Font > Font Size

Font Size: Change font size in pixels as per your requirement

Search: settings.json, Open file and add this line in settings.json file:

{
    "editor.fontSize": 20
}

Note: Save file after changes

Option 3:

Press Ctrl + Shift + P

Search: Editor Font Zoom In

• Just click on it, your font size will be increased

First, you have to create two animation resources in res/anim dir

slide_up.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
    android:duration="@android:integer/config_mediumAnimTime"
    android:fromYDelta="100%"
    android:interpolator="@android:anim/accelerate_interpolator"
    android:toXDelta="0">
</translate>
</set>

slide_bottom.xml

<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate 
    android:duration="@android:integer/config_mediumAnimTime" 
    android:fromYDelta="0%p" 
    android:interpolator="@android:anim/accelerate_interpolator" 
    android:toYDelta="100%p">
</translate>
</set>

then you have to create a style

<style name="DialogAnimation">
    <item name="android:windowEnterAnimation">@anim/slide_up</item>
    <item name="android:windowExitAnimation">@anim/slide_bottom</item>
</style>

and add this line to your class

dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation; //style id

Based in http://www.devexchanges.info/2015/10/showing-dialog-with-animation-in-android.html

You can't declare an extern local method inside of a method, or any other method with an attribute. Move your DLL import into the class:

using System.Runtime.InteropServices;


public class WindowHandling
{
    [DllImport("User32.dll")]
    public static extern int SetForegroundWindow(IntPtr point);

    public void ActivateTargetApplication(string processName, List<string> barcodesList)
    {
        Process p = Process.Start("notepad++.exe");
        p.WaitForInputIdle();
        IntPtr h = p.MainWindowHandle;
        SetForegroundWindow(h);
        SendKeys.SendWait("k");
        IntPtr processFoundWindow = p.MainWindowHandle;
    }
}

select @currentTerm = CurrentTerm, @termID = TermID, @endDate = EndDate
    from table1
    where IsCurrent = 1

The most easy way is use nano DateTime as long format. System.nanoTime();

In IE7, you can bring up firebug lite for the current page by pasting the following in the address bar:

javascript:var firebug=document.createElement('script');firebug.setAttribute('src','http://getfirebug.com/releases/lite/1.2/firebug-lite-compressed.js');document.body.appendChild(firebug);(function(){if(window.firebug.version){firebug.init();}else{setTimeout(arguments.callee);}})();void(firebug);

See http://getfirebug.com/lite.html.

Names surrounded by double underscores are "special" to Python. They're listed in the Python Language Reference, section 3, "Data model".

Just want to add the following points:

Yon can not push until you commit as we use git push to push commits made on your local branch to a remote repository.

The git push command takes two arguments:

A remote name, for example, origin A branch name, for example, master

For example:

git push  <REMOTENAME> <BRANCHNAME> 
git push  origin       master

Capitalize the app to App will surely work.

I see a couple of issues.

First:

ser.read() is only going to return 1 byte at a time.

If you specify a count

ser.read(5)

it will read 5 bytes (less if timeout occurrs before 5 bytes arrive.)

If you know that your input is always properly terminated with EOL characters, better way is to use

ser.readline()

That will continue to read characters until an EOL is received.

Second:

Even if you get ser.read() or ser.readline() to return multiple bytes, since you are iterating over the return value, you will still be handling it one byte at a time.

Get rid of the

for line in ser.read():

and just say:

line = ser.readline()

There are other options for you to benchmark:

1.) A window function will return the actual size directly (tested in MariaDB):

SELECT 
  `mytable`.*,
  COUNT(*) OVER() AS `total_count`
FROM `mytable`
ORDER BY `mycol`
LIMIT 10, 20

2.) Thinking out of the box, most of the time users don't need to know the EXACT size of the table, an approximate is often good enough.

SELECT `TABLE_ROWS` AS `rows_approx`
FROM `INFORMATION_SCHEMA`.`TABLES`
WHERE `TABLE_SCHEMA` = DATABASE()
  AND `TABLE_TYPE` = "BASE TABLE"
  AND `TABLE_NAME` = ?

I did at VagrantFile:

REMOTE_IP = %x{/usr/local/bin/vagrant ssh-config | /bin/grep -i HostName | /usr/bin/cut -d\' \' -f4}
run "ping #{REMOTE_IP}"

As you can see, I used the "%x{}" ruby function.

Without more details as to what the question is exactly asking, I am going to answer the title of the question,

Create an Array:

String[] myArray = new String[2];
int[] intArray = new int[2];

// or can be declared as follows
String[] myArray = {"this", "is", "my", "array"};
int[] intArray = {1,2,3,4};

Create an ArrayList:

ArrayList<String> myList = new ArrayList<String>();
myList.add("Hello");
myList.add("World");

ArrayList<Integer> myNum = new ArrayList<Integer>();
myNum.add(1);
myNum.add(2);

This means, create an ArrayList of String and Integer objects. You cannot use int because thats a primitive data types, see the link for a list of primitive data types.

Create a Stack:

Stack myStack = new Stack();
// add any type of elements (String, int, etc..)
myStack.push("Hello");
myStack.push(1);

Create an Queue: (using LinkedList)

Queue<String> myQueue = new LinkedList<String>();
Queue<Integer> myNumbers = new LinkedList<Integer>();
myQueue.add("Hello");
myQueue.add("World");
myNumbers.add(1);
myNumbers.add(2);

Same thing as an ArrayList, this declaration means create an Queue of String and Integer objects.

Update:

In response to your comment from the other given answer,

i am pretty confused now, why are using string. and what does <String> means

We are using String only as a pure example, but you can add any other object, but the main point is that you use an object not a primitive type. Each primitive data type has their own primitive wrapper class, see link for list of primitive data type's wrapper class.

I have posted some links to explain the difference between the two, but here are a list of primitive types

• byte
• short
• char
• int
• long
• boolean
• double
• float

Which means, you are not allowed to make an ArrayList of integer's like so:

ArrayList<int> numbers = new ArrayList<int>(); 
           ^ should be an object, int is not an object, but Integer is!
ArrayList<Integer> numbers = new ArrayList<Integer>();
            ^ perfectly valid

Also, you can use your own objects, here is my Monster object I created,

public class Monster {
   String name = null;
   String location = null;
   int age = 0;

public Monster(String name, String loc, int age) { 
   this.name = name;
   this.loc = location;
   this.age = age;
 }

public void printDetails() {
   System.out.println(name + " is from " + location +
                                     " and is " + age + " old.");
 }
} 

Here we have a Monster object, but now in our Main.java class we want to keep a record of all our Monster's that we create, so let's add them to an ArrayList

public class Main {
    ArrayList<Monster> myMonsters = new ArrayList<Monster>();

public Main() {
    Monster yetti = new Monster("Yetti", "The Mountains", 77);
    Monster lochness = new Monster("Lochness Monster", "Scotland", 20);

    myMonsters.add(yetti); // <-- added Yetti to our list
    myMonsters.add(lochness); // <--added Lochness to our list
  
    for (Monster m : myMonsters) {
        m.printDetails();
     }
   }

public static void main(String[] args) {
    new Main();
 }
}

(I helped my girlfriend's brother with a Java game, and he had to do something along those lines as well, but I hope the example was well demonstrated)

private String message;
private ScreenManager s;


//Here is an example of code to add the keyListener() as suggested; modify 
public void init(){
Window w = s.getFullScreenWindow();
w.addKeyListener(this);

public void keyPressed(KeyEvent e){
    int keyCode = e.getKeyCode();
        if(keyCode == KeyEvent.VK_F5)
            message = "Pressed: " + KeyEvent.getKeyText(keyCode);
}

Assuming that you have posted valid JSON,

@app.route('/api/add_message/<uuid>', methods=['GET', 'POST'])
def add_message(uuid):
    content = request.json
    print content['uuid']
    # Return data as JSON
    return jsonify(content)

You have to do two things:

• be sure to have imported right appcompat-v7 library in your project structure -> dependencies
• change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.

Use the .text() function:

var text = $("<p> example ive got a string</P>").text();

Update: As Brilliand points out below, if the input string does not contain any tags and you are unlucky enough, it might be treated as a CSS selector. So this version is more robust:

var text = $("<div/>").html("<p> example ive got a string</P>").text();

I had faced a similar problem. Every thing was okay, the "readystate" was 4, but the "status" was 0. It was because I was using a Apache PHP portable server and my file in which I used the "XMLHttpRequest" object was a html file. I changed the file extension to php and the problem was solved.

Sometime we should see the note from the warnin SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details..

This happens when no appropriate SLF4J binding could be found on the class path

You can search the reason why this warning comes.
Adding one of the jar from *slf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar* to the class path should solve the problem.

compile "org.slf4j:slf4j-simple:1.6.1"

for example add the above code to your build.gradle or the corresponding code to pom.xml for maven project.

As of 2020 the fastest MD5 implementation is probably written in WASM (Web Assembly).

hash-wasm is a library that implements MD5 hash in WASM.

You can find the benchmarks here.

You can either install it with npm:

npm i hash-wasm

or just add a script tag

<script src="https://cdn.jsdelivr.net/npm/hash-wasm"></script>

then use the hashwasm global variable.

Example:

async function run() {
  console.log('MD5:', await hashwasm.md5('The quick brown fox jumps over the lazy dog'));
}

run();

outputs

MD5: 9e107d9d372bb6826bd81d3542a419d6

This should be easily resolved by importing headers from Angular:

import { Http, Headers } from "@angular/http";

In addition to DESCRIBE TABLE, you can use the command below

DESCRIBE INDEXES FOR TABLE *tablename* SHOW DETAIL 

to get information about the table's indexes.

The most comprehensive detail about a table on Db2 for Linux, UNIX, and Windows can be obtained from the db2look utility, which you can run from a remote client or directly on the Db2 server as a local user. The tool produces the DDL and other information necessary to mimic tables and their statistical data. The docs for db2look in Db2 11.5 are here.

The following db2look command will connect to the SALESDB database and obtain the DDL statements necessary to recreate the ORDERS table

db2look -d SALESDB -e -t ORDERS

programData is hidden folder so you have to change the option from setting to show hidden folder and then make the change in my.ini file present in that.

Be sure to update the correct my.ini file because it can waste a lot of your time if you keep updating wrong file.

You can look into service to see which my.ini is configured in this service.

Instead of ((t[1])/length) * t[1] += string, you should use string += ((t[1])/length) * t[1]. (The other syntax issue - int is not iterable - will be your exercise to figure out.)

I have done this way

function uniqeId() {
   var ranDom = Math.floor(new Date().valueOf() * Math.random())
   return _.uniqueId(ranDom);
}

If you have been given a database file and have not installed the correct server (either SQLite or MySQL), try this tool: https://dbconvert.com/sqlite/mysql/ The trial version allows converting the first 50 records of each table, the rest of the data is watermarked. This is a Windows program, and can either dump into a running database server, or can dump output to a .sql file

My problem, it showed an error called "The class Form1 can be designed, but is not the first class in the file. Visual Studio requires that designers use the first class in the file. Move the class code so that it is the first class in the file and try loading the designer again. ". So I moved the Form class to the first one and it worked. :)

I suggest a LinkedHashMap or a TreeMap. A LinkedHashMap keeps the keys in the order they were inserted, while a TreeMap is kept sorted via a Comparator or the natural Comparable ordering of the elements.

Since it doesn't have to keep the elements sorted, LinkedHashMap should be faster for most cases; TreeMap has O(log n) performance for containsKey, get, put, and remove, according to the Javadocs, while LinkedHashMap is O(1) for each.

If your API that only expects a predictable sort order, as opposed to a specific sort order, consider using the interfaces these two classes implement, NavigableMap or SortedMap. This will allow you not to leak specific implementations into your API and switch to either of those specific classes or a completely different implementation at will afterwards.

You can do this:

CSS:

#container {
    height:175px;
}

#container h3{
    position:absolute;
    bottom:0;
    left:0;
}

Then in HTML:

<div class="row">
    <div class="col-sm-6">
        <img src="//placehold.it/600x300" alt="Logo" />
    </div>
    <div id="container" class="col-sm-6">
        <h3>Some Text</h3>
    </div>
</div>

EDIT: add the <

In C arrays, arr[3] and 3[arr] are the same, and their equivalent pointer notations are *(arr + 3) to *(3 + arr). But on the contrary [arr]3 or [3]arr is not correct and will result into syntax error, as (arr + 3)* and (3 + arr)* are not valid expressions. The reason is dereference operator should be placed before the address yielded by the expression, not after the address.

To fix this solution i followed: this

1.Click Start and then type Run

2.Type services.msc and click OK

3.Scroll down the list and locate that the VMware Authorization service.

4.Click Start the service, unless the service is showing a status of Started.

As a workaround you can use the fact percent vertical padding and margin are computed from the container width. It's quite a ugly solution and I don't know if you'll be able to use it but well, it works: http://jsfiddle.net/bFWT9/

</html>

html, body, div {
    height: 100%;

    margin-top: -75%;
    padding-top: 75%;

You can use CSS under legend.green-color a:hover to do it.

legend.green-color a:hover {

Here's an example of going from a list of strings, to a single string, back to a list of strings.

Compiling:

$ javac test.java
$ java test

Running:

    Initial list:

        "abc"
        "def"
        "ghi"
        "jkl"
        "mno"

    As single string:

        "[abc, def, ghi, jkl, mno]"

    Reconstituted list:

        "abc"
        "def"
        "ghi"
        "jkl"
        "mno"

Source code:

import java.util.*;
public class test {

    public static void main(String[] args) {
        List<String> listOfStrings= new ArrayList<>();
        listOfStrings.add("abc");
        listOfStrings.add("def");
        listOfStrings.add("ghi");
        listOfStrings.add("jkl");
        listOfStrings.add("mno");

        show("\nInitial list:", listOfStrings);

        String singleString = listOfStrings.toString();

        show("As single string:", singleString);

        List<String> reconstitutedList = Arrays.asList(
             singleString.substring(0, singleString.length() - 1)
                  .substring(1).split("[\\s,]+"));

        show("Reconstituted list:", reconstitutedList);
    }

    public static void show(String title, Object operand) {
        System.out.println(title + "\n");
        if (operand instanceof String) {
            System.out.println("    \"" + operand + "\"");
        } else {
            for (String string : (List<String>)operand)
                System.out.println("    \"" + string + "\"");
        }
        System.out.println("\n");
    }
}

You are using:

expect(fn).toThrow(e)

But if you'll have a look on the function comment (expected is string):

294 /**
295  * Matcher that checks that the expected exception was thrown by the actual.
296  *
297  * @param {String} expected
298  */
299 jasmine.Matchers.prototype.toThrow = function(expected) {

I suppose you should probably write it like this (using lambda - anonymous function):

expect(function() { parser.parse(raw); } ).toThrow("Parsing is not possible");

This is confirmed in the following example:

expect(function () {throw new Error("Parsing is not possible")}).toThrow("Parsing is not possible");

Douglas Crockford strongly recommends this approach, instead of using "throw new Error()" (prototyping way):

throw {
   name: "Error",
   message: "Parsing is not possible"
}

Extension methods I commonly use to solve this problem:

public static string RemoveAfter(this string value, string character)
    {
        int index = value.IndexOf(character);
        if (index > 0)
        {
            value = value.Substring(0, index);
        }
        return value;
    }

    public static string RemoveBefore(this string value, string character)
    {
        int index = value.IndexOf(character);
        if (index > 0)
        {
            value = value.Substring(index + 1);
        }
        return value;
    }

In a function, use as

render: function (args) {
    if (args.value != 0)

Due to goto10's observation, I put together the following code to protected against loosing other filters with setting the max length:

/**
 * This sets the maximum length in characters of an EditText view. Since the
 * max length must be done with a filter, this method gets the current
 * filters. If there is already a length filter in the view, it will replace
 * it, otherwise, it will add the max length filter preserving the other
 * 
 * @param view
 * @param length
 */
public static void setMaxLength(EditText view, int length) {
    InputFilter curFilters[];
    InputFilter.LengthFilter lengthFilter;
    int idx;

    lengthFilter = new InputFilter.LengthFilter(length);

    curFilters = view.getFilters();
    if (curFilters != null) {
        for (idx = 0; idx < curFilters.length; idx++) {
            if (curFilters[idx] instanceof InputFilter.LengthFilter) {
                curFilters[idx] = lengthFilter;
                return;
            }
        }

        // since the length filter was not part of the list, but
        // there are filters, then add the length filter
        InputFilter newFilters[] = new InputFilter[curFilters.length + 1];
        System.arraycopy(curFilters, 0, newFilters, 0, curFilters.length);
        newFilters[curFilters.length] = lengthFilter;
        view.setFilters(newFilters);
    } else {
        view.setFilters(new InputFilter[] { lengthFilter });
    }
}

When I had to rasterize svgs on the server, I ended up using P/Invoke to call librsvg functions (you can get the dlls from a windows version of the GIMP image editing program).

[DllImport("kernel32.dll", SetLastError = true)]
static extern bool SetDllDirectory(string pathname);

[DllImport("libgobject-2.0-0.dll", SetLastError = true)]
static extern void g_type_init(); 

[DllImport("librsvg-2-2.dll", SetLastError = true)]
static extern IntPtr rsvg_pixbuf_from_file_at_size(string file_name, int width, int height, out IntPtr error);

[DllImport("libgdk_pixbuf-2.0-0.dll", CallingConvention = CallingConvention.Cdecl, CharSet = CharSet.Ansi)]
static extern bool gdk_pixbuf_save(IntPtr pixbuf, string filename, string type, out IntPtr error, __arglist);

public static void RasterizeSvg(string inputFileName, string outputFileName)
{
    bool callSuccessful = SetDllDirectory("C:\\Program Files\\GIMP-2.0\\bin");
    if (!callSuccessful)
    {
        throw new Exception("Could not set DLL directory");
    }
    g_type_init();
    IntPtr error;
    IntPtr result = rsvg_pixbuf_from_file_at_size(inputFileName, -1, -1, out error);
    if (error != IntPtr.Zero)
    {
        throw new Exception(Marshal.ReadInt32(error).ToString());
    }
    callSuccessful = gdk_pixbuf_save(result, outputFileName, "png", out error, __arglist(null));
    if (!callSuccessful)
    {
        throw new Exception(error.ToInt32().ToString());
    }
}

You can use jQuery method to check whether a value is numeric or other type.

$.isNumeric()

Example

$.isNumeric("46")

true

$.isNumeric(46)

true

$.isNumeric("dfd")

false

Setp 1 : Download the following apk files. 1)com.google.android.gms.apk (https://androidfilehost.com/?fid=95916177934534438) 2)com.android.vending-4.4.22.apk (https://androidfilehost.com/?fid=23203820527945795)

Step 2 : Create a new AVD without the google API's

Step 3 : Run the AVD (Start the emulator)

Step 4 : Install the downloaded apks using adb .

     1)adb install com.google.android.gms-6.7.76_\(1745988-038\)-6776038-minAPI9.apk  
     2)adb install com.android.vending-4.4.22.apk

adb come up with android sdks/studio

Step 5 : Create the application in google developer console

Step 6 : Configure the api key in your Androidmanifest.xml and google api version.

Note : In step1 you need to download the apk based on your Android API level(..18,19,21..) and google play services version (5,5.1,6,6.5......)

This will work 100%.

Whatever approach you take, make sure in the end that you have an updated version of curl and libcurl. You can do curl --version and see the versions.

Here's what I did to get the latest curl version installed in Ubuntu:

1. sudo add-apt-repository "deb http://mirrors.kernel.org/ubuntu wily main"
2. sudo apt-get update
3. sudo apt-get install curl

The oracle limit is 1000 parameters. The issue has been resolved by hibernate in version 4.1.7 although by splitting the passed parameter list in sets of 500 see JIRA HHH-1123

To get the fields info too, you can use the following:

SELECT TABLE_SCHEMA, TABLE_NAME, 
       COLUMN_NAME, substring(DATA_TYPE, 1,1) AS DATA_TYPE
FROM information_schema.COLUMNS 
WHERE TABLE_SCHEMA NOT IN("information_schema", "mysql", "performance_schema") 
ORDER BY TABLE_SCHEMA, TABLE_NAME, ORDINAL_POSITION

For targeting IE only in my stylesheets, I use this Sass Mixin :

@mixin ie-only {
  @media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
    @content;
  }
}

The solution documented by Apple in Technical Q&A QA1747 Debugging Deployed iOS Apps for Xcode 6 is:

1. Choose Window -> Devices from the Xcode menu.
2. Choose the device in the left column.
3. Click the up-triangle at the bottom left of the right hand panel to show the device console.

And if you need authorized user in templates (e.g. JSP) use

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
<sec:authentication property="principal.yourCustomField"/>

together with

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-taglibs</artifactId>
        <version>${spring-security.version}</version>

Many solutions come to mind, depending on what you want to achive:

Every List item is key and value

for( Object o : list ) {
    map.put(o,o);
}

List elements have something to look them up, maybe a name:

for( MyObject o : list ) {
    map.put(o.name,o);
}

List elements have something to look them up, and there is no guarantee that they are unique: Use Googles MultiMaps

for( MyObject o : list ) {
    multimap.put(o.name,o);
}

Giving all the elements the position as a key:

for( int i=0; i<list.size; i++ ) {
    map.put(i,list.get(i));
}

...

It really depends on what you want to achive.

As you can see from the examples, a Map is a mapping from a key to a value, while a list is just a series of elements having a position each. So they are simply not automatically convertible.

Step 1:

jmx-console-users.properties 
admin=admin

Step 2:

jmx-console-roles.properties 
admin=JBossAdmin,HttpInvoker

Step 3: Restart or start the JBoss instance.

Now you should good to go...

Go to the jmx console, enter JBoss login URL, then enter admin as username and admin password.

Try to use this for remove validation on the click on cancel

 function HideValidators() {
            var lblMsg = document.getElementById('<%= lblRFDChild.ClientID %>');
            lblMsg.innerHTML = "";           
            if (window.Page_Validators) {
                for (var vI = 0; vI < Page_Validators.length; vI++) {
                    var vValidator = Page_Validators[vI];
                    vValidator.isvalid = true;
                    ValidatorUpdateDisplay(vValidator);
                }
            } 
        }

var excel=new ActiveXObject("Excel.Application"); var book=excel.Workbooks.Open(your_full_file_name_here.xls); var sheet=book.Sheets.Item(1); var value=sheet.Range("A1");

when you have the sheet. You could use VBA functions as you do in Excel.

MSSQL requires that variables within procedures be DECLAREd and folks use the @Variable syntax (DECLARE @TEXT VARCHAR(25) = 'text'). Also, MS allows for declares within any block in the procedure, unlike mySQL which requires all the DECLAREs at the top.

While good on the command line, I feel using the "set = @variable" within stored procedures in mySQL is risky. There is no scope and variables live across scope boundaries. This is similar to variables in JavaScript being declared without the "var" prefix, which are then the global namespace and create unexpected collisions and overwrites.

I am hoping that the good folks at mySQL will allow DECLARE @Variable at various block levels within a stored procedure. Notice the @ (at sign). The @ sign prefix helps to separate variable names from table column names - as they are often the same. Of course, one can always add an "v" or "l_" prefix, but the @ sign is a handy and succinct way to have the variable name match the column you might be extracting the data from without clobbering it.

MySQL is new to stored procedures and they have done a good job for their first version. It will be a pleaure to see where they take it form here and to watch the server side aspects of the language mature.

Using recursion, you're incurring the cost of a function call with each "iteration", whereas with a loop, the only thing you usually pay is an increment/decrement. So, if the code for the loop isn't much more complicated than the code for the recursive solution, loop will usually be superior to recursion.

I've had the same problem you describe. The web site I'm building can be accessed from a mobile phone and from the browser so I need an api to allow users to signup, login and do some specific tasks. Furthermore, I need to support scalability, the same code running on different processes/machines.

Because users can CREATE resources (aka POST/PUT actions) you need to secure your api. You can use oauth or you can build your own solution but keep in mind that all the solutions can be broken if the password it's really easy to discover. The basic idea is to authenticate users using the username, password and a token, aka the apitoken. This apitoken can be generated using node-uuid and the password can be hashed using pbkdf2

Then, you need to save the session somewhere. If you save it in memory in a plain object, if you kill the server and reboot it again the session will be destroyed. Also, this is not scalable. If you use haproxy to load balance between machines or if you simply use workers, this session state will be stored in a single process so if the same user is redirected to another process/machine it will need to authenticate again. Therefore you need to store the session in a common place. This is typically done using redis.

When the user is authenticated (username+password+apitoken) generate another token for the session, aka accesstoken. Again, with node-uuid. Send to the user the accesstoken and the userid. The userid (key) and the accesstoken (value) are stored in redis with and expire time, e.g. 1h.

Now, every time the user does any operation using the rest api it will need to send the userid and the accesstoken.

If you allow the users to signup using the rest api, you'll need to create an admin account with an admin apitoken and store them in the mobile app (encrypt username+password+apitoken) because new users won't have an apitoken when they sign up.

The web also uses this api but you don't need to use apitokens. You can use express with a redis store or use the same technique described above but bypassing the apitoken check and returning to the user the userid+accesstoken in a cookie.

If you have private areas compare the username with the allowed users when they authenticate. You can also apply roles to the users.

Summary:

An alternative without apitoken would be to use HTTPS and to send the username and password in the Authorization header and cache the username in redis.

In python the with keyword is used when working with unmanaged resources (like file streams). It is similar to the using statement in VB.NET and C#. It allows you to ensure that a resource is "cleaned up" when the code that uses it finishes running, even if exceptions are thrown. It provides 'syntactic sugar' for try/finally blocks.

From Python Docs:

The with statement clarifies code that previously would use try...finally blocks to ensure that clean-up code is executed. In this section, I’ll discuss the statement as it will commonly be used. In the next section, I’ll examine the implementation details and show how to write objects for use with this statement.

The with statement is a control-flow structure whose basic structure is:

with expression [as variable]:
    with-block

The expression is evaluated, and it should result in an object that supports the context management protocol (that is, has __enter__() and __exit__() methods).

Update fixed VB callout per Scott Wisniewski's comment. I was indeed confusing with with using.

I hate to post my own answer, but some answers recently have ignored the solution I posted in my own question, suggesting approaches that are nothing short of foolhardy.

In short - you do not need to edit any Windows user account privileges at all. Doing so only introduces risk. The process is entirely managed in IIS using inherited privileges.

Applying Modify/Write Permissions to the Correct User Account

1. Right-click the domain when it appears under the Sites list, and choose Edit Permissions

   

   Under the Security tab, you will see MACHINE_NAME\IIS_IUSRS is listed. This means that IIS automatically has read-only permission on the directory (e.g. to run ASP.Net in the site). You do not need to edit this entry.

   

2. Click the Edit button, then Add...

3. In the text box, type IIS AppPool\MyApplicationPoolName, substituting MyApplicationPoolName with your domain name or whatever application pool is accessing your site, e.g. IIS AppPool\mydomain.com

   

4. Press the Check Names button. The text you typed will transform (notice the underline):

   

5. Press OK to add the user

6. With the new user (your domain) selected, now you can safely provide any Modify or Write permissions

   

python supports arbitrarily large integers naturally:

example:

>>> 10**1000
10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000

You could even get, for example of a huge integer value, fib(4000000).

But still it does not (for now) supports an arbitrarily large float !!

If you need one big, large, float then check up on the decimal Module. There are examples of use on these foruns: OverflowError: (34, 'Result too large')

Another reference: http://docs.python.org/2/library/decimal.html

You can even using the gmpy module if you need a speed-up (which is likely to be of your interest): Handling big numbers in code

I worked from Misko's code above and this is what I've done with it. This is a more current solution since $defer has been changed to $timeout. Substituting $timeout however will wait for the timeout period (in Misko's code, 1 second), then return the data hoping it's resolved in time. With this way, it returns asap.

function PhoneListCtrl($scope, phones) {
  $scope.phones = phones;
  $scope.orderProp = 'age';
}

PhoneListCtrl.resolve = {

  phones: function($q, Phone) {
    var deferred = $q.defer();

    Phone.query(function(phones) {
        deferred.resolve(phones);
    });

    return deferred.promise;
  }
}

I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

$("#panel").toggle().toggle();

it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

I found in a class file outside the scope of the Page, the above way (which I always have used) didn't work.
I found a workaround in this "context" as follows:

HttpContext.Current.Session.Add("currentUser", appUser);

and

(AppUser) HttpContext.Current.Session["currentUser"]

Otherwise the compiler was expecting a string when I pointed the object at the session object.

html, body{ 
  width:100%;
}

This tells the html to be 100% wide. But 100% refers to the whole browser window width, so no more than that.

You may want to set a min width instead.

html, body{ 
  min-width:100%;
}

So it will be 100% as a minimum, bot more if needed.

Python boolean keywords are True and False, notice the capital letters. So like this:

a = True;
b = True;
match_var = True if a == b else False
print match_var;

When compiled and run, this prints:

True
