Just Overload the default constructor of Model class and pass any relevant parameter which you may or may not use. By this you can easily supply default values for attributes. Below is an example.

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.ComponentModel.DataAnnotations;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Aim.Data.Domain
{
    [MetadataType(typeof(LoginModel))]
    public partial class Login
    {       
        public Login(bool status)
        {
            this.CreatedDate = DateTime.Now;
            this.ModifiedDate = DateTime.Now;
            this.Culture = "EN-US";
            this.IsDefaultPassword = status;
            this.IsActive = status;
            this.LoginLogs = new HashSet<LoginLog>();
            this.LoginLogHistories = new HashSet<LoginLogHistory>();
        }


    }

    public class LoginModel
    {

        [Key]
        [ScaffoldColumn(false)] 
        public int Id { get; set; }
        [Required]
        public string LoginCode { get; set; }
        [Required]
        public string Password { get; set; }
        public string LastPassword { get; set; }     
        public int UserGroupId { get; set; }
        public int FalseAttempt { get; set; }
        public bool IsLocked { get; set; }
        public int CreatedBy { get; set; }       
        public System.DateTime CreatedDate { get; set; }
        public Nullable<int> ModifiedBy { get; set; }      
        public Nullable<System.DateTime> ModifiedDate { get; set; }       
        public string Culture { get; set; }        
        public virtual ICollection<LoginLog> LoginLogs { get; set; }
        public virtual ICollection<LoginLogHistory> LoginLogHistories { get; set; }
    }

}

Just remove or comment the following lines

public void ConfigureServices(IServiceCollection services) { /Identity/ services.AddDbContext(options => options.UseSqlServer(Configuration["ConnectionStrings:IdentityConnection"])); services.AddIdentity<AppUser, IdentityRole>().AddEntityFrameworkStores().AddDefaultTokenProviders(); /End/

        /*Identity Login Url */
        services.ConfigureApplicationCookie(opts => opts.LoginPath = "/Login");

        services.AddMvc();
        //Authorization
        //services.AddMvc(config =>
        //{
        //    var policy = new AuthorizationPolicyBuilder()
        //                    .RequireAuthenticatedUser()
        //                    .Build();
        //    config.Filters.Add(new AuthorizeFilter(policy));
        //});
    }

Though there are good answers, I will show the google recommended way:

1)First create a Theme for splash screen: you have a theme called splashscreenTheme, your launcher theme would be:

<style name="splashscreenTheme">
  <item name="android:windowBackground">@drawable/launch_screen</item>
</style>

Note:

android:windowBackground already sets your splashscreen image no
need to do this in UI again.

you can also use color here instead of a drawable.

2)Set the theme to manifest of splashscreenActivity

   <activity
            android:name=".activity.splashscreenActivity"
            android:screenOrientation="portrait"
            android:theme="@style/splashscreenTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

3)make sure you launch_screen drawable is not in drawable folder if your image is not small.

It will result in faster launch screen start and save you from the black screen

It also avoids extra overdraw

From what I understand of your request, this should work:

<script>
//  var status  = document.getElementsByID("uniqueID"); // this works too
var status  = document.getElementsByName("status")[0];
var jsonArr = [];

for (var i = 0; i < status.options.length; i++) {
    jsonArr.push({
        id: status.options[i].text,
        optionValue: status.options[i].value
    });
}
</script>

Try the export function of phpMyAdmin.

I think there is also a possibility to copy the database files from one server to another, but I do not have a server available at the moment so I can't test it.

== and != do not take into account the data type of the variables you compare. So these would all return true:

'0'   == 0
false == 0
NULL  == false

=== and !== do take into account the data type. That means comparing a string to a boolean will never be true because they're of different types for example. These will all return false:

'0'   === 0
false === 0
NULL  === false

You should compare data types for functions that return values that could possibly be of ambiguous truthy/falsy value. A well-known example is strpos():

// This returns 0 because F exists as the first character, but as my above example,
// 0 could mean false, so using == or != would return an incorrect result
var_dump(strpos('Foo', 'F') != false);  // bool(false)
var_dump(strpos('Foo', 'F') !== false); // bool(true), it exists so false isn't returned

The problem is with the way you are printing the Time data

java.util.Date utilDate = new java.util.Date();
java.sql.Timestamp sq = new java.sql.Timestamp(utilDate.getTime());
System.out.println(sa); //this will print the milliseconds as the toString() has been written in that format

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
System.out.println(sdf.format(timestamp)); //this will print without ms

Converting an int to a byte in Python 3:

    n = 5    
    bytes( [n] )

>>> b'\x05'

;) guess that'll be better than messing around with strings

I don't think you can drop all tables in one hit but you can do the following to get the commands:

select 'drop table ' || name || ';' from sqlite_master
    where type = 'table';

The output of this is a script that will drop the tables for you. For indexes, just replace table with index.

You can use other clauses in the where section to limit which tables or indexes are selected (such as "and name glob 'pax_*'" for those starting with "pax_").

You could combine the creation of this script with the running of it in a simple bash (or cmd.exe) script so there's only one command to run.

If you don't care about any of the information in the DB, I think you can just delete the file it's stored in off the hard disk - that's probably faster. I've never tested this but I can't see why it wouldn't work.

MySQL is notoriously cranky, especially with regards to foreign keys and triggers. I am right now in the process of fine tuning one such database, and ran into this problem. It is not self evident or intuitive, so here it goes:

Besides checking if the two columns you want to reference in the relationship have the same data type, you must also make sure the column on the table you are referencing is an index. If you are using the MySQL Workbench, select the tab "Indexes" right next to "Columns" and make sure the column referenced by the foreign key is an index. If not, create one, name it something meaningful, and give it the type "INDEX".

A good practice is to clean up the tables involved in relationships to make sure previous attempts did not create indexes you don't want or need.

I hope it helped, some MySQL errors are maddening to track.

Please try below:

DECLARE @Today DATETIME;  
SET @Today = '12/5/2007';  

SET LANGUAGE Italian;  
SELECT DATENAME(month, @Today) AS 'Month Name';  

SET LANGUAGE us_english;  
SELECT DATENAME(month, @Today) AS 'Month Name' ;  
GO

Use pd.concat to merge a list of DataFrame into a single big DataFrame.

appended_data = []
for infile in glob.glob("*.xlsx"):

    # store DataFrame in list
    appended_data.append(data)
# see pd.concat documentation for more info
appended_data = pd.concat(appended_data)
# write DataFrame to an excel sheet 
appended_data.to_excel('appended.xlsx')

For Symfony 2.7 and newer

See this answer here.

1st working option

{{ app.request.scheme ~'://' ~ app.request.httpHost ~ asset('bundles/acmedemo/images/search.png') }}

2nd working option - preferred

Just made a quick test with a clean new Symfony copy. There is also another option which combines scheme and httpHost:

{{ app.request.getSchemeAndHttpHost() ~ asset('bundles/acmedemo/images/search.png') }}
{# outputs #}
{# http://localhost/Symfony/web/bundles/acmedemo/css/demo.css  #}

Just a recommendation:

I'd recommend using the DOM table implementation, it's very straight forward and easy to use, you really don't need jQuery for this task.

var table = document.getElementById('tblOne');

var rowLength = table.rows.length;

for(var i=0; i<rowLength; i+=1){
  var row = table.rows[i];

  //your code goes here, looping over every row.
  //cells are accessed as easy

  var cellLength = row.cells.length;
  for(var y=0; y<cellLength; y+=1){
    var cell = row.cells[y];

    //do something with every cell here
  }
}

How to use an IF statement in the MySQL "select list":

select if (1>2, 2, 3);                         //returns 3
select if(1<2,'yes','no');                     //returns yes
SELECT IF(STRCMP('test','test1'),'no','yes');  //returns no

How to use an IF statement in the MySQL where clause search condition list:

create table penguins (id int primary key auto_increment, name varchar(100))
insert into penguins (name) values ('rico')
insert into penguins (name) values ('kowalski')
insert into penguins (name) values ('skipper')

select * from penguins where 3 = id
-->3    skipper

select * from penguins where (if (true, 2, 3)) = id
-->2    kowalski

How to use an IF statement in the MySQL "having clause search conditions":

select * from penguins 
where 1=1
having (if (true, 2, 3)) = id
-->1    rico

Use an IF statement with a column used in the select list to make a decision:

select (if (id = 2, -1, 1)) item
from penguins
where 1=1
--> 1
--> -1
--> 1

If statements embedded in SQL queries is a bad "code smell". Bad code has high "WTF's per minute" during code review. This is one of those things. If I see this in production with your name on it, I'm going to automatically not like you.

FormatDateTime(Now, DateFormat.ShortDate)

PATH mode is used in generating XML from a SELECT query

1. SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH;  

Ouput:
<row>
<ID>1</ID>
<Name>aaa</Name>
</row>

<row>
<ID>1</ID>
<Name>bbb</Name>
</row>

<row>
<ID>1</ID>
<Name>ccc</Name>
</row>

<row>
<ID>1</ID>
<Name>ddd</Name>
</row>

<row>
<ID>1</ID>
<Name>eee</Name>
</row>

The Output is element-centric XML where each column value in the resulting rowset is wrapped in an row element. Because the SELECT clause does not specify any aliases for the column names, the child element names generated are the same as the corresponding column names in the SELECT clause.

For each row in the rowset a tag is added.

2.
SELECT   
       ID,  
       Name  
FROM temp1
FOR XML PATH('');

Ouput:
<ID>1</ID>
<Name>aaa</Name>
<ID>1</ID>
<Name>bbb</Name>
<ID>1</ID>
<Name>ccc</Name>
<ID>1</ID>
<Name>ddd</Name>
<ID>1</ID>
<Name>eee</Name>

For Step 2: If you specify a zero-length string, the wrapping element is not produced.

3. 

    SELECT   

           Name  
    FROM temp1
    FOR XML PATH('');

    Ouput:
    <Name>aaa</Name>
    <Name>bbb</Name>
    <Name>ccc</Name>
    <Name>ddd</Name>
    <Name>eee</Name>

4. SELECT   
        ',' +Name  
FROM temp1
FOR XML PATH('')

Ouput:
,aaa,bbb,ccc,ddd,eee

In Step 4 we are concatenating the values.

5. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1

Ouput:
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee
1   ,aaa,bbb,ccc,ddd,eee


6. SELECT ID,
    abc = (SELECT   
            ',' +Name  
    FROM temp1
    FOR XML PATH('') )
FROM temp1 GROUP by iD

Ouput:
ID  abc
1   ,aaa,bbb,ccc,ddd,eee

In Step 6 we are grouping the date by ID.

STUFF( source_string, start, length, add_string ) Parameters or Arguments source_string The source string to modify. start The position in the source_string to delete length characters and then insert add_string. length The number of characters to delete from source_string. add_string The sequence of characters to insert into the source_string at the start position.

SELECT ID,
    abc = 
    STUFF (
        (SELECT   
                ',' +Name  
        FROM temp1
        FOR XML PATH('')), 1, 1, ''
    )
FROM temp1 GROUP by iD

Output:
-----------------------------------
| Id        | Name                |
|---------------------------------|
| 1         | aaa,bbb,ccc,ddd,eee |
-----------------------------------

Just for the records the analogous java version:

Tuple2<String, String> sc[] = sparkConf.getAll();
for (int i = 0; i < sc.length; i++) {
    System.out.println(sc[i]);
}

I believe your "P" as the dataWithBytes param

NSData *keydata = [NSData dataWithBytes:P length:len];

should be "buf"

NSData *keydata = [NSData dataWithBytes:buf length:len];

since i2d_PrivateKey puts the pointer to the output buffer p at the end of the buffer and waiting for further input, and buf is still pointing to the beginning of your buffer.

The following code works for me where pkey is a pointer to an EVP_PKEY:

unsigned char *buf, *pp;
int len = i2d_PrivateKey(pkey, NULL);
buf = OPENSSL_malloc(len); 
pp = buf;
i2d_PrivateKey(pkey, &pp);

NSData* pkeyData = [NSData dataWithBytes:(const void *)buf length:len];
DLog(@"Private key in hex (%d): %@", len, pkeyData);

You can use an online converter to convert your binary data into base 64 (http://tomeko.net/online_tools/hex_to_base64.php?lang=en) and compare it to the private key in your cert file after using the following command and checking the output of mypkey.pem:

openssl pkcs12 -in myCert.p12 -nocerts -nodes -out mypkey.pem

I referenced your question and this EVP function site for my answer.

See sync-request: https://github.com/ForbesLindesay/sync-request

Example:

var request = require('sync-request');
var res = request('GET', 'http://example.com');
console.log(res.getBody());

Known ID

$(".container > #first");

or

$(".container").children("#first");

or since IDs should be unique within a single document:

$("#first");

The last one is of course the fastest.

Unknown ID

Since you're saying that you don't know their ID top couple of the upper selectors (where #first is written), can be changed to:

$(".container > div");
$(".container").children("div");

The last one (of the first three selectors) that only uses ID is of course not possible to be changed in this way.

If you also need to filter out only those child DIV elements that define ID attribute you'd write selectors down this way:

$(".container > div[id]");
$(".container").children("div[id]");

Attach click handler

Add the following code to attach click handler to any of your preferred selector:

// use selector of your choice and call 'click' on it
$(".container > div").click(function(){
    // if you need element's ID
    var divID = this.id;
    cache your element if you intend to use it multiple times
    var clickedDiv = $(this);
    // add CSS class to it
    clickedDiv.addClass("add-some-class");
    // do other stuff that needs to be done
});

CSS3 Selectors specification

I would also like to point you to CSS3 selector specification that jQuery uses. It will help you lots in the future because there may be some selectors you're not aware of at all and could make your life much much easier.

After your edited question

I'm not completey sure that I know what you're after even though you've written some pseudo code... Anyway. Some parts can still be answered:

$(".container > div[id]").each(function(){
    var context = $(this);
    // get menu parent element: Sub: Show Grid
    // maybe I'm not appending to the correct element here but you should know
    context.appendTo(context.parent().parent());
    context.text("Show #" + this.id);
    context.attr("href", "");
    context.click(function(evt){
        evt.preventDefault();
        $(this).toggleClass("showgrid");
    })
});

the last thee context usages could be combined into a single chained one:

context.text(...).attr(...).click(...);

Regarding DOM elements

You can always get the underlaying DOM element from the jQuery result set.

$(...).get(0)
// or
$(...)[0]

will get you the first DOM element from the jQuery result set. jQuery result is always a set of elements even though there's none in them or only one.

But when I used .each() function and provided an anonymous function that will be called on each element in the set, this keyword actually refers to the DOM element.

$(...).each(function(){
    var DOMelement = this;
    var jQueryElement = $(this);
    ...
});

I hope this clears some things for your.

You've mixed tabs and spaces. __init__ is actually defined nested inside another method, so your class doesn't have its own __init__ method, and it inherits object.__init__ instead. Open your code in Notepad instead of whatever editor you're using, and you'll see your code as Python's tab-handling rules see it.

This is why you should never mix tabs and spaces. Stick to one or the other. Spaces are recommended.

I can not see where do you declare context. For the purpose of the intent creation you can use MainActivity.this

 lv.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                Intent intent = new Intent(MainActivity.this, SendMessage.class);
                String message = "abc";
                intent.putExtra(EXTRA_MESSAGE, message);
                startActivity(intent);
            }
        });

To retrieve the object upon you have clicked you can use the AdapterView:

ListEntry entry = (ListEntry) parent.getItemAtPosition(position);

Not a full answer Ok so this is just to supplement the information about parseInt, which is still very valid. Express doesn't allow the req or res objects to be modified at all (immutable). So if you want to modify/use this data effectively, you must copy it to another variable (var year = req.params.year).

Working one liner if you want a single result from the collection:

$ipAddy = [System.Net.Dns]::GetHostAddresses("yahoo.com")[0].IPAddressToString;

Are you on Windows? The underlying socket implementation on Windows seems not to support the SO_TIMEOUT option very well. See also this answer: setSoTimeout on a client socket doesn't affect the socket

I know an answer has already been accepted for this problem but someone asked in the comments if there was a solution that could be done outside the web.config. I had a ListView producing the exact same error and setting EnableViewState to false resolved this problem for me.

The trap shell builtin allows catching signals, and other useful conditions, including failed command execution (i.e., a non-zero return status). So if you don't want to explicitly test return status of every single command you can say trap "your shell code" ERR and the shell code will be executed any time a command returns a non-zero status. For example:

trap "echo script failed; exit 1" ERR

Note that as with other cases of catching failed commands, pipelines need special treatment; the above won't catch false | true.

It's much easier if you use Response.raw and shutil.copyfileobj():

import requests
import shutil

def download_file(url):
    local_filename = url.split('/')[-1]
    with requests.get(url, stream=True) as r:
        with open(local_filename, 'wb') as f:
            shutil.copyfileobj(r.raw, f)

    return local_filename

This streams the file to disk without using excessive memory, and the code is simple.

In Linux there are two space 1st is user space and another one is kernal space. user space consist of only user application which u want to run. as the kernal service there is process management, file management, signal handling, memory management, thread management, and so many services are present there. if u run the application from the user space that appliction interact with only kernal service. and that service is interact with device driver which is present between hardware and kernal. the main benefit of kernal space and user space seperation is we can acchive a security by the virus.bcaz of all user application present in user space, and service is present in kernal space. thats why linux doesn,t affect from the virus.

First, close all instances of Google Chrome. There should be no instances of chrome.exe running in the Windows Task Manager. Then

• Go to %LOCALAPPDATA%\Google\Chrome\User Data\Default\.
• Open the file "Preferences" in a text editor like Notepad.
• First, resave the file to something like "Preference - Old" without any extension (i.e. no .txt). This will serve as a backup, should something go wrong.
• Look for a section called "browser." Inside that section, you should find a subsection called window_placement. Under window_placement you will see things like "bottom", "left", "right", etc. with numbers after them.

You will need to play around with these numbers to get your desired window size and placement. When finished, save this file with the name "Preferences" again with no extension. This will overwrite the existing Preferences file. Open Chrome and see how you did. If you're not satisfied with the size and placement, close Chrome and change the numbers in the Preferences file until you get what you want.

It sounds like you need to use recursion. Make a function to iterate through a list, and if it hits an item that is also a list, call itself to iterate on the member. Here's a link to something similar:

http://www.saltycrane.com/blog/2008/08/python-recursion-example-navigate-tree-data/

 typeof(text) === 'string' || text instanceof String; 

you can use this, it will work for both case as

1. var text="foo"; // typeof will work

2. String text= new String("foo"); // instanceof will work

Set the type of the field as TIMESTAMP too.

Bit old but still one of my favs:

jQuery used to ONLY have the callback functions for success and error and complete.

Then, they decided to support promises with the jqXHR object and that's when they added .done(), .fail(), .always(), etc... in the spirit of the promise API. These new methods serve much the same purpose as the callbacks but in a different form. You can use whichever API style works better for your coding style.

As people get more and more familiar with promises and as more and more async operations use that concept, I suspect that more and more people will move to the promise API over time, but in the meantime jQuery supports both.

The .success() method has been deprecated in favor of the common promise object method names.

From the jQuery doc, you can see how various promise methods relate to the callback types:

jqXHR.done(function( data, textStatus, jqXHR ) {}); An alternative construct to the success callback option, the .done() method replaces the deprecated jqXHR.success() method. Refer to deferred.done() for implementation details.

jqXHR.fail(function( jqXHR, textStatus, errorThrown ) {}); An alternative construct to the error callback option, the .fail() method replaces the deprecated .error() method. Refer to deferred.fail() for implementation details.

jqXHR.always(function( data|jqXHR, textStatus, jqXHR|errorThrown ) { }); An alternative construct to the complete callback option, the .always() method replaces the deprecated .complete() method.

In response to a successful request, the function's arguments are the same as those of .done(): data, textStatus, and the jqXHR object. For failed requests the arguments are the same as those of .fail(): the jqXHR object, textStatus, and errorThrown. Refer to deferred.always() for implementation details.

jqXHR.then(function( data, textStatus, jqXHR ) {}, function( jqXHR, textStatus, errorThrown ) {}); Incorporates the functionality of the .done() and .fail() methods, allowing (as of jQuery 1.8) the underlying Promise to be manipulated. Refer to deferred.then() for implementation details.

If you want to code in a way that is more compliant with the ES6 Promises standard, then of these four options you would only use .then().

tf.nn.softmax computes the forward propagation through a softmax layer. You use it during evaluation of the model when you compute the probabilities that the model outputs.

tf.nn.softmax_cross_entropy_with_logits computes the cost for a softmax layer. It is only used during training.

The logits are the unnormalized log probabilities output the model (the values output before the softmax normalization is applied to them).

You can call more of 1 function filters in the same ng-repeat filter

<article data-ng-repeat="result in results | filter:search() | filter:filterFn()" class="result">

Here is:

var array : [String] = ["One", "Two", "Three"]
let userDefault = UserDefaults.standard
// set
userDefault.set(array, forKey: "array")
// retrieve 
if let fetchArray = userDefault.array(forKey: "array") as? [String] {
    // code 
}

There are a few issues at play here. The first is the issue of declaring a static method without defining it. This is the difference between

public interface Foo {
  public static int bar();
}

and

public interface Foo {
  public static int bar() {
    ...
  }
}

The first is impossible for the reasons that Espo mentions: you don't know which implementing class is the correct definition.

Java could allow the latter; and in fact, starting in Java 8, it does!

Another way to check where a specific table is stored would be execute this query on the hive interactive interface:

show create table table_name;

where table_name is the name of the subject table.

An example for the above query on 'customers' table would be something like this:

CREATE TABLE `customers`(
  `id` string, 
  `name` string)
COMMENT 'Imported by sqoop on 2016/03/01 13:01:49'
ROW FORMAT DELIMITED 
  FIELDS TERMINATED BY ',' 
  LINES TERMINATED BY '\n' 
STORED AS INPUTFORMAT 
  'org.apache.hadoop.mapred.TextInputFormat' 
OUTPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
LOCATION
  'hdfs://quickstart.cloudera:8020/user/hive/warehouse/
   sqoop_workspace.db/customers'
TBLPROPERTIES (
  'COLUMN_STATS_ACCURATE'='true', 
  'numFiles'='4', 
  'totalSize'='77', 
  'transient_lastDdlTime'='1456866115')

LOCATION in the example above is where you should focus on. That is your hdfs location for hive warehouse.

Don't forget to like if you like this solution. Cheers!

@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs sizes so you won't notice, but if you used anything else (e.g. col-sm, col-md, etc), you'd understand.

Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/

.left-side {
  background-color: blue;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.something {
  height: 100%;
  background-color: red;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.row {
  background-color: green;
  overflow: hidden;
}

Use a correlated sub-query. Very simple, here you go:

SELECT 
somedate, 
(SELECT SUM(somevalue) FROM TestTable t2 WHERE t2.somedate<=t1.somedate) AS running_total
FROM TestTable t1
GROUP BY somedate
ORDER BY somedate

The code might not be exactly correct, but I'm sure that the idea is.

The GROUP BY is in case a date appears more than once, you would only want to see it once in the result set.

If you don't mind seeing repeating dates, or you want to see the original value and id, then the following is what you want:

SELECT 
id,
somedate, 
somevalue,
(SELECT SUM(somevalue) FROM TestTable t2 WHERE t2.somedate<=t1.somedate) AS running_total
FROM TestTable t1
ORDER BY somedate

With "Please select one Item"

@Html.DropDownListFor(model => model.ContentManagement_Send_Section,
  new List<SelectListItem> { new SelectListItem { Value = "0", Text = "Plese Select one Item" } }
    .Concat(db.NameOfPaperSections.Select(x => new SelectListItem { Text = x.NameOfPaperSection, Value = x.PaperSectionID.ToString() })),
  new { @class = "myselect" })

If you really want to get rid of the warnings, one thing you can do is create a class that extends from the generic class.

For example, if you're trying to use

private Map<String, String> someMap = new HashMap<String, String>();

You can create a new class like such

public class StringMap extends HashMap<String, String>()
{
    // Override constructors
}

Then when you use

someMap = (StringMap) getApplicationContext().getBean("someMap");

The compiler DOES know what the (no longer generic) types are, and there will be no warning. This may not always be the perfect solution, some might argue this kind of defeats the purpose of generic classes, but you're still re-using all of the same code from the generic class, you're just declaring at compile time what type you want to use.

I'm sure there are other ways to accomplish this, but one solution would be to use join through the Query Builder.

If you have tables set up something like this:

users
    id
    ...

friends
    id
    user_id
    friend_id
    ...

votes, comments and status_updates (3 tables)
    id
    user_id
    ....

In your User model:

class User extends Eloquent {
    public function friends()
    {
        return $this->hasMany('Friend');
    }
}

In your Friend model:

class Friend extends Eloquent {
    public function user()
    {
        return $this->belongsTo('User');
    }
}

Then, to gather all the votes for the friends of the user with the id of 1, you could run this query:

$user = User::find(1);
$friends_votes = $user->friends()
    ->with('user') // bring along details of the friend
    ->join('votes', 'votes.user_id', '=', 'friends.friend_id')
    ->get(['votes.*']); // exclude extra details from friends table

Run the same join for the comments and status_updates tables. If you would like votes, comments, and status_updates to be in one chronological list, you can merge the resulting three collections into one and then sort the merged collection.

Edit

To get votes, comments, and status updates in one query, you could build up each query and then union the results. Unfortunately, this doesn't seem to work if we use the Eloquent hasMany relationship (see comments for this question for a discussion of that problem) so we have to modify to queries to use where instead:

$friends_votes = 
    DB::table('friends')->where('friends.user_id','1')
    ->join('votes', 'votes.user_id', '=', 'friends.friend_id');

$friends_comments = 
    DB::table('friends')->where('friends.user_id','1')
    ->join('comments', 'comments.user_id', '=', 'friends.friend_id');

$friends_status_updates = 
    DB::table('status_updates')->where('status_updates.user_id','1')
    ->join('friends', 'status_updates.user_id', '=', 'friends.friend_id');

$friends_events = 
    $friends_votes
    ->union($friends_comments)
    ->union($friends_status_updates)
    ->get();

At this point, though, our query is getting a bit hairy, so a polymorphic relationship with and an extra table (like DefiniteIntegral suggests below) might be a better idea.

Yes, a struct is identical to a class except for the default access level (member-wise and inheritance-wise). (and the extra meaning class carries when used with a template)

Every functionality supported by a class is consequently supported by a struct. You'd use methods the same as you'd use them for a class.

struct foo {
  int bar;
  foo() : bar(3) {}   //look, a constructor
  int getBar() 
  { 
    return bar; 
  }
};

foo f;
int y = f.getBar(); // y is 3

Just to clearify: man-page of sed on OSX (10.8; Darwin Kernel Version 12.4.0) says:

[...]

Sed Regular Expressions

 The regular expressions used in sed, by default, are basic regular expressions (BREs, see re_format(7) for more information), but extended
 (modern) regular expressions can be used instead if the -E flag is given.  In addition, sed has the following two additions to regular
 expressions:

 1.   In a context address, any character other than a backslash (``\'') or newline character may be used to delimit the regular expression.
      Also, putting a backslash character before the delimiting character causes the character to be treated literally.  For example, in the
      context address \xabc\xdefx, the RE delimiter is an ``x'' and the second ``x'' stands for itself, so that the regular expression is
      ``abcxdef''.

 2.   The escape sequence \n matches a newline character embedded in the pattern space.  You cannot, however, use a literal newline charac-
      ter in an address or in the substitute command.

[...]

so I guess one have to use tr - as mentioned above - or the nifty

sed "s/,/^M
/g"

note: you have to type <ctrl>-v,<return> to get '^M' in vi editor

Isn't easier than doing like :

1- Install jquery in your project:

yarn add jquery

2- Import jquery and start playing with DOM:

import $ from 'jquery';

There is another way of performing the fit, which is by using the 'lmfit' package. It basically uses the cuve_fit but is much better in fitting and offers complex fitting as well. Detailed step by step instructions are given in the below link. http://cars9.uchicago.edu/software/python/lmfit/model.html#model.best_fit

For example, a logout button can be written like this:

<button class="btn btn-primary" onclick="location.href={% url 'logout'%}">Logout</button>

Where logout endpoint:

#urls.py:
url(r'^logout/$', auth_views.logout, {'next_page': '/'}, name='logout'),

You could use string.Join:

List<string> list = new List<string>()
{
    "Red",
    "Blue",
    "Green"
};

string output = string.Join(Environment.NewLine, list.ToArray());    
Console.Write(output);

The result would be:

Red    
Blue    
Green

As an alternative to Environment.NewLine, you can replace it with a string based line-separator of your choosing.

The class declaration goes into the header file. It is important that you add the #ifndef include guards, or if you are on a MS platform you also can use #pragma once. Also I have omitted the private, by default C++ class members are private.

// A2DD.h
#ifndef A2DD_H
#define A2DD_H

class A2DD
{
  int gx;
  int gy;

public:
  A2DD(int x,int y);
  int getSum();

};

#endif

and the implementation goes in the CPP file:

// A2DD.cpp
#include "A2DD.h"

A2DD::A2DD(int x,int y)
{
  gx = x;
  gy = y;
}

int A2DD::getSum()
{
  return gx + gy;
}

I am not sure this will help but I resolved the issue by importing mongoose like below and implementing it as below

const mongoose = require('mongoose')

_id: new mongoose.Types.ObjectId(),

Try using the XOR operator, without using built-in functions:

a = [3,2,3,2,3,5,6,7].sort!

result = a.reject.with_index do |ele,index|
  res = (a[index+1] ^ ele)
  res == 0
end

print result

With built-in functions:

a = [3,2,3,2,3,5,6,7]

a.uniq

This is my setup to use Geany as an editor for Git:

git config --global core.editor C:/path/to/geany.bat

with the following content in geany.bat:

#!/bin/sh
"C:\Program Files\Geany\bin\Geany.exe" --new-instance "$*"

It works in both a DOS console and msysgit.

1. define it like your_field DATETIME NULL DEFAULT NULL
2. dont insert a blank string, insert a NULL INSERT INTO x(your_field)VALUES(NULL)

you can just type bash or if you always want to use bash:

on "iTerm2"

• Go to preferences > Profiles > Command
• Select "Command" from the dropdown
• Type bash

Test by closing iTerm and open it again

I don't think the jar tool supports this natively, but you can just unzip a JAR file with "unzip" and specify the output directory with that with the "-d" option, so something like:

$ unzip -d /home/foo/bar/baz /home/foo/bar/Portal.ear Binaries.war

& is bitwise. && is logical.

& evaluates both sides of the operation.
&& evaluates the left side of the operation, if it's true, it continues and evaluates the right side.

1. Create an instance of Random class somewhere. Note that it's pretty important not to create a new instance each time you need a random number. You should reuse the old instance to achieve uniformity in the generated numbers. You can have a static field somewhere (be careful about thread safety issues):

   static Random rnd = new Random();
   

2. Ask the Random instance to give you a random number with the maximum of the number of items in the ArrayList:

   int r = rnd.Next(list.Count);
   

3. Display the string:

   MessageBox.Show((string)list[r]);
   

Would this parser help you?

https://github.com/fiann/jquery.ogp

It parses meta OG data to JSON, so you can just use the data directly. If you prefer, you can read/write them directly using JQuery, of course. For example:

$("meta[property='og:title']").attr("content", document.title);
$("meta[property='og:url']").attr("content", location.toString());

Note the single-quotes around the attribute values; this prevents parse errors in jQuery.

I had to uncomment extension=openssl in php.ini file for everything to work!

It is also good idea to use supervisord or runit[1] for service management.

[1] https://github.com/phusion/baseimage-docker

Adding the following line to the top of your .py file:

# -*- coding: utf-8 -*-

allows you to encode strings directly in your script, like this:

utfstr = "????"

Use Arrays.copyOf my friend.

To my mind the case for a PT (as @Nathan Fisher) is a 'no brainer', but I would add a column to facilitate ordering by rank (up or down):

OPS is entered as VALUES (Sum of) twice so I have renamed the column labels to make clearer which is which. The PT is in a different sheet from the data but could be in the same sheet.

Rank is set with a right click on a data point selected in that column and Show Values As... and Rank Largest to Smallest (there are other options) with the Base field as Player and the filter is a Value Filters, Top 10... one:

Once in a PT the power of that feature can very easily be applied to view the data in many other ways, with no change of formula (there isn't one!).

In the case of a tie for the last position included in the filter both results are included (Top 5 would show six or more results). A tie for top rank between just two players would show as 1 1 3 4 5 for Top 5.

It's very simple. Just Set width of img to 100%

SOLUTION: (Notice: this solution is for datatables version 1.10.4 (at the moment) not legacy version).

CLARIFICATION Per the API documentation (1.10.15), the API can be accessed three ways:

1. The modern definition of DataTables (upper camel case):

   var datatable = $( selector ).DataTable();

2. The legacy definition of DataTables (lower camel case):

   var datatable = $( selector ).dataTable().api();

3. Using the new syntax.

   var datatable = new $.fn.dataTable.Api( selector );

Then load the data like so:

$.get('myUrl', function(newDataArray) {
    datatable.clear();
    datatable.rows.add(newDataArray);
    datatable.draw();
});

Use draw(false) to stay on the same page after the data update.

API references:

https://datatables.net/reference/api/clear()

https://datatables.net/reference/api/rows.add()

https://datatables.net/reference/api/draw()

You can use CSS3 media query for this. Write like this:

CSS

.wrapper { 
  border : 2px solid #000; 
  overflow:hidden;
}

.wrapper div {
   min-height: 200px;
   padding: 10px;
}
#one {
  background-color: gray;
  float:left; 
  margin-right:20px;
  width:140px;
  border-right:2px solid #000;
}
#two { 
  background-color: white;
  overflow:hidden;
  margin:10px;
  border:2px dashed #ccc;
  min-height:170px;
}

@media screen and (max-width: 400px) {
   #one { 
    float: none;
    margin-right:0;
    width:auto;
    border:0;
    border-bottom:2px solid #000;    
  }
}

HTML

<div class="wrapper">
    <div id="one">one</div>
    <div id="two">two</div>
</div>

Easiest way to solve this problem is install ASP.NET MVC 3 from Web Platforms installer.

http://www.microsoft.com/web/downloads/

Or by using Nuget command

Install-Package Microsoft.AspNet.Mvc -Version 3.0.50813.1

The activity in which you want to add listview footer and i have also generate an event on listview footer click.

  public class MainActivity extends Activity

         {

            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            ListView  list_of_f = (ListView) findViewById(R.id.list_of_f);

            LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            View view = inflater.inflate(R.layout.web_view, null);  // i have open a webview on the listview footer

            RelativeLayout  layoutFooter = (RelativeLayout) view.findViewById(R.id.layoutFooter);

            list_of_f.addFooterView(view);

        }

}

Simply, @Id: This annotation specifies the primary key of the entity. 

@GeneratedValue: This annotation is used to specify the primary key generation strategy to use. i.e Instructs database to generate a value for this field automatically. If the strategy is not specified by default AUTO will be used. 

GenerationType enum defines four strategies: 
1. Generation Type . TABLE, 
2. Generation Type. SEQUENCE,
3. Generation Type. IDENTITY   
4. Generation Type. AUTO

GenerationType.SEQUENCE

With this strategy, underlying persistence provider must use a database sequence to get the next unique primary key for the entities. 

GenerationType.TABLE

With this strategy, underlying persistence provider must use a database table to generate/keep the next unique primary key for the entities. 

GenerationType.IDENTITY
This GenerationType indicates that the persistence provider must assign primary keys for the entity using a database identity column. IDENTITY column is typically used in SQL Server. This special type column is populated internally by the table itself without using a separate sequence. If underlying database doesn't support IDENTITY column or some similar variant then the persistence provider can choose an alternative appropriate strategy. In this examples we are using H2 database which doesn't support IDENTITY column.

GenerationType.AUTO
This GenerationType indicates that the persistence provider should automatically pick an appropriate strategy for the particular database. This is the default GenerationType, i.e. if we just use @GeneratedValue annotation then this value of GenerationType will be used. 

Reference:- https://www.logicbig.com/tutorials/java-ee-tutorial/jpa/jpa-primary-key.html

We put the default values in the database through migrations (by specifying the :default option on each column definition) and let Active Record use these values to set the default for each attribute.

IMHO, this approach is aligned with the principles of AR : convention over configuration, DRY, the table definition drives the model, not the other way around.

Note that the defaults are still in the application (Ruby) code, though not in the model but in the migration(s).

Depending on the language you're using it's going to be something simple like

CInt(CDate("1970-1-1") - CDate(Today()))

Ironically enough, yesterday was day 40,000 if you use 1/1/1900 as "day zero" like many computer systems use.

- (UIImage *)image:(UIImage*)originalImage scaledToSize:(CGSize)size
{
    //avoid redundant drawing
    if (CGSizeEqualToSize(originalImage.size, size))
    {
        return originalImage;
    }

    //create drawing context
    UIGraphicsBeginImageContextWithOptions(size, NO, 0.0f);

    //draw
    [originalImage drawInRect:CGRectMake(0.0f, 0.0f, size.width, size.height)];

    //capture resultant image
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    //return image
    return image;
}

The .length property only tracks properties with numeric indexes (keys). You're using strings for keys.

You can do this:

var arr_jq_TabContents = {}; // no need for an array

arr_jq_TabContents["Main"] = jq_TabContents_Main;
arr_jq_TabContents["Guide"] = jq_TabContents_Guide;
arr_jq_TabContents["Articles"] = jq_TabContents_Articles;
arr_jq_TabContents["Forum"] = jq_TabContents_Forum;

for (var key in arr_jq_TabContents) {
    console.log(arr_jq_TabContents[key]);
}

To be safe, it's a good idea in loops like that to make sure that none of the properties are unexpected results of inheritance:

for (var key in arr_jq_TabContents) {
  if (arr_jq_TabContents.hasOwnProperty(key))
    console.log(arr_jq_TabContents[key]);
}

edit — it's probably a good idea now to note that the Object.keys() function is available on modern browsers and in Node etc. That function returns the "own" keys of an object, as an array:

Object.keys(arr_jq_TabContents).forEach(function(key, index) {
  console.log(this[key]);
}, arr_jq_TabContents);

The callback function passed to .forEach() is called with each key and the key's index in the array returned by Object.keys(). It's also passed the array through which the function is iterating, but that array is not really useful to us; we need the original object. That can be accessed directly by name, but (in my opinion) it's a little nicer to pass it explicitly, which is done by passing a second argument to .forEach() — the original object — which will be bound as this inside the callback. (Just saw that this was noted in a comment below.)

As suggested by @EboMike I saved the bitmap in a file named myImage in the internal storage of my application not accessible my other apps. Here's the code of that part:

public String createImageFromBitmap(Bitmap bitmap) {
    String fileName = "myImage";//no .png or .jpg needed
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
        fo.write(bytes.toByteArray());
        // remember close file output
        fo.close();
    } catch (Exception e) {
        e.printStackTrace();
        fileName = null;
    }
    return fileName;
}

Then in the next activity you can decode this file myImage to a bitmap using following code:

Bitmap bitmap = BitmapFactory.decodeStream(context
                    .openFileInput("myImage"));//here context can be anything like getActivity() for fragment, this or MainActivity.this

Note A lot of checking for null and scaling bitmap's is ommited.

Here is a similar solution, but it uses Array.prototype.reduce

function countCharacters(char, string) {
  return string.split('').reduce((acc, ch) => ch === char ? acc + 1: acc, 0)
}

As was mentioned, String.prototype.split works much faster than String.prototype.replace.

At the end of the day I'm not interested in combining streams, but in obtaining the combined result of processing each element of all those streams.

While combining streams might prove to be cumbersome (thus this thread), combining their processing results is fairly easy.

The key to solve is to create your own collector and ensure that the supplier function for the new collector returns the same collection every time (not a new one), the code below illustrates this approach.

package scratchpad;

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.stream.Collector;
import java.util.stream.Stream;

public class CombineStreams {
    public CombineStreams() {
        super();
    }

    public static void main(String[] args) {
        List<String> resultList = new ArrayList<>();
        Collector<String, List<String>, List<String>> collector = Collector.of(
                () -> resultList,
                (list, item) -> {
                    list.add(item);
                },
                (llist, rlist) -> {
                    llist.addAll(rlist);
                    return llist;
                }
        );
        String searchString = "Wil";

        System.out.println("After processing first stream\n"
                + createFirstStream().filter(name -> name.contains(searchString)).collect(collector));
        System.out.println();

        System.out.println("After processing second stream\n"
                + createSecondStream().filter(name -> name.contains(searchString)).collect(collector));
        System.out.println();

        System.out.println("After processing third stream\n"
                + createThirdStream().filter(name -> name.contains(searchString)).collect(collector));
        System.out.println();

    }

Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.

I stumbled upon this question because I created, successfully built and published a PyPI Package, but couldn't execute it after installation. The $PATHvariable was correctly set.

In my case the problem was that I hadn't set the entry_pointin the setup.py file:

entry_points = {'console_scripts':

['YOUR_CONSOLE_COMMAND=MODULE_NAME.FILE_NAME:FUNCTION_NAME'],},

When you can not assume that column b comes before c you can use match to find the column number of both, min to get the lower column number and seq_len to get a sequence until this column. Then you can use this index first as a positive subset, than place the new column d and then use the sequence again as a negative subset.

i <- seq_len(min(match(c("b", "c"), colnames(x))))
data.frame(x[i], d, x[-i])
#cbind(x[i], d, x[-i]) #Alternative
#  a b  d c
#1 1 4 10 7
#2 2 5 11 8
#3 3 6 12 9

In case you know that column b comes before c you can place the new column d after b:

i <- seq_len(match("b", colnames(x)))
data.frame(x[i], d, x[-i])
#  a b  d c
#1 1 4 10 7
#2 2 5 11 8
#3 3 6 12 9

Data:

x <- data.frame(a = 1:3, b = 4:6, c = 7:9)
d <- 10:12

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

I have found a fairly simple way to do this.

Initially, through your Anaconda Prompt, you can follow the steps in this official Tensorflow site - here. You have to follow the steps as is, no deviation.

Later, you open the Anaconda Navigator. In Anaconda Navigator, go to Applications On --- section. Select the drop down list, after following above steps you must see an entry - tensorflow into it. Select tensorflow and let the environment load.

Then, select Jupyter Notebook in this new context, and install it, let the installation get over.

After that you can run the Jupyter notebook like the regular notebook in tensorflow environment.

You can actually still use ".css" and apply css transitions to the div being affected. So continue using ".css" and add the below styles to your stylesheet for "#hfont1". Since ".css" allows for a lot more properties than ".animate", this is always my preferred method.

#hfont1 {
    -webkit-transition: width 0.4s;
    transition: width 0.4s;
}

This arstechnica article describes the basic steps:

Start by visiting the program portal and make sure that your developer certificate is up to date. It expires every six months and, if you haven't requested that a new one be issued, you cannot submit software to App Store. For most people experiencing the "pink upload of doom," though, their certificates are already valid. What next?

Open your Xcode project and check that you've set the active SDK to one of the device choices, like Device - 2.2. Accidentally leaving the build settings to Simulator can be a big reason for the pink rejection. And that happens more often than many developers would care to admit.

Next, make sure that you've chosen a build configuration that uses your distribution (not your developer) certificate. Check this by double-clicking on your target in the Groups & Files column on the left of the project window. The Target Info window will open. Click the Build tab and review your Code Signing Identity. It should be iPhone Distribution: followed by your name or company name.

You may also want to confirm your application identifier in the Properties tab. Most likely, you'll have set the identifier properly when debugging with your developer certificate, but it never hurts to check.

The top-left of your project window also confirms your settings and configuration. It should read something like "Device - 2.2 | Distribution". This shows you the active SDK and configuration.

If your settings are correct but you still aren't getting that upload finished properly, clean your builds. Choose Build > Clean (Command-Shift-K) and click Clean. Alternatively, you can manually trash the build folder in your Project from Finder. Once you've cleaned, build again fresh.

If this does not produce an app that when zipped properly loads to iTunes Connect, quit and relaunch Xcode. I'm not kidding. This one simple trick solves more signing problems and "pink rejections of doom" than any other solution already mentioned.

I find that generating random colors tends to create colors that do not have enough contrast for my taste. The easiest way I have found to get around that is to pre-populate a list of very different colors. For every new string, assign the next color in the list:

// Takes any string and converts it into a #RRGGBB color.
var StringToColor = (function(){
    var instance = null;

    return {
    next: function stringToColor(str) {
        if(instance === null) {
            instance = {};
            instance.stringToColorHash = {};
            instance.nextVeryDifferntColorIdx = 0;
            instance.veryDifferentColors = ["#000000","#00FF00","#0000FF","#FF0000","#01FFFE","#FFA6FE","#FFDB66","#006401","#010067","#95003A","#007DB5","#FF00F6","#FFEEE8","#774D00","#90FB92","#0076FF","#D5FF00","#FF937E","#6A826C","#FF029D","#FE8900","#7A4782","#7E2DD2","#85A900","#FF0056","#A42400","#00AE7E","#683D3B","#BDC6FF","#263400","#BDD393","#00B917","#9E008E","#001544","#C28C9F","#FF74A3","#01D0FF","#004754","#E56FFE","#788231","#0E4CA1","#91D0CB","#BE9970","#968AE8","#BB8800","#43002C","#DEFF74","#00FFC6","#FFE502","#620E00","#008F9C","#98FF52","#7544B1","#B500FF","#00FF78","#FF6E41","#005F39","#6B6882","#5FAD4E","#A75740","#A5FFD2","#FFB167","#009BFF","#E85EBE"];
        }

        if(!instance.stringToColorHash[str])
            instance.stringToColorHash[str] = instance.veryDifferentColors[instance.nextVeryDifferntColorIdx++];

            return instance.stringToColorHash[str];
        }
    }
})();

// Get a new color for each string
StringToColor.next("get first color");
StringToColor.next("get second color");

// Will return the same color as the first time
StringToColor.next("get first color");

While this has a limit to only 64 colors, I find most humans can't really tell the difference after that anyway. I suppose you could always add more colors.

While this code uses hard-coded colors, you are at least guaranteed to know during development exactly how much contrast you will see between colors in production.

Color list has been lifted from this SO answer, there are other lists with more colors.

Server Side Code :-

<?php


// it will print whole json string, which you access after json_decocde in php
$myData = json_decode($_POST['myData']);
print_r($myData);

?>

Due to angular behaviour there is no direct method for normal post behaviour at PHP server, so you have to manage it in json objects.

You can use filters available in swift to filter content from an array instead of using a predicate like in Objective-C.

An example in Swift 4.0 is as follows:

var stringArray = ["foundation","coredata","coregraphics"]
stringArray = stringArray.filter { $0.contains("core") }

In the above example, since each element in the array is a string you can use the contains method to filter the array.

If the array contains custom objects, then the properties of that object can be used to filter the elements similarly.

Your compiled classes may need to be recompiled from the source with the new jars.

Try running "mvn clean" and then rebuild

Using fileSystem (fs) tests will trigger error objects, which you then would need to wrap in a try/catch statement. Save yourself some effort, and use a feature introduce in the 0.4.x branch.

var path = require('path');

var dirs = ['one', 'two', 'three'];

dirs.map(function(dir) {
  path.exists(dir, function(exists) {
    var message = (exists) ? dir + ': is a directory' : dir + ': is not a directory';
    console.log(message);
  });
});

I had the same problem. Restart my android device and closed the adb.exe process. With that I could solve the problem

In Linux command Prompt, I would first stop all postgresql processes that are running by tying this command sudo /etc/init.d/postgresql restart

type the command bg to check if other postgresql processes are still running

then followed by dropdb dbname to drop the database

sudo /etc/init.d/postgresql restart
bg
dropdb dbname

This works for me on linux command prompt

You should be able to "MINUS" or "EXCEPT" depending on the flavor of SQL used by your DBMS.

select * from tableA
minus
select * from tableB

If the query returns no rows then the data is exactly the same.

C++98 doesn't provide a direct syntax for anything but zeroing (or for non-POD elements, value-initializing) the array. For that you just write C(): arr() {}.

I thing Roger Pate is wrong about the alleged limitations of C++0x aggregate initialization, but I'm too lazy to look it up or check it out, and it doesn't matter, does it? EDIT: Roger was talking about "C++03", I misread it as "C++0x". Sorry, Roger. ?

A C++98 workaround for your current code is to wrap the array in a struct and initialize it from a static constant of that type. The data has to reside somewhere anyway. Off the cuff it can look like this:

class C 
{
public:
    C() : arr( arrData ) {}

private:
     struct Arr{ int elem[3]; };
     Arr arr;
     static Arr const arrData;
};

C::Arr const C::arrData = {{1, 2, 3}};

Thanks to @the-tin-man for putting together the benchmarks!

Alas, I don't really like any of those solutions. Either they require an extra step to get the result ([0] = '', .strip!) or they aren't very semantic/clear about what's happening ([1..-1]: "Um, a range from 1 to negative 1? Yearg?"), or they are slow or lengthy to write out (.gsub, .length).

What we are attempting is a 'shift' (in Array parlance), but returning the remaining characters, rather than what was shifted off. Let's use our Ruby to make this possible with strings! We can use the speedy bracket operation, but give it a good name, and take an arg to specify how much we want to chomp off the front:

class String
  def eat!(how_many = 1)
    self.replace self[how_many..-1]
  end
end

But there is more we can do with that speedy-but-unwieldy bracket operation. While we are at it, for completeness, let's write a #shift and #first for String (why should Array have all the fun??), taking an arg to specify how many characters we want to remove from the beginning:

class String
  def first(how_many = 1)
    self[0...how_many]
  end

  def shift(how_many = 1)
    shifted = first(how_many)
    self.replace self[how_many..-1]
    shifted
  end
  alias_method :shift!, :shift
end

Ok, now we have a good clear way of pulling characters off the front of a string, with a method that is consistent with Array#first and Array#shift (which really should be a bang method??). And we can easily get the modified string as well with #eat!. Hm, should we share our new eat!ing power with Array? Why not!

class Array
  def eat!(how_many = 1)
    self.replace self[how_many..-1]
  end
end

Now we can:

> str = "[12,23,987,43" #=> "[12,23,987,43"
> str.eat!              #=> "12,23,987,43"
> str                   #=> "12,23,987,43"

> str.eat!(3)           #=> "23,987,43"
> str                   #=> "23,987,43"

> str.first(2)          #=> "23"
> str                   #=> "23,987,43"

> str.shift!(3)         #=> "23,"
> str                   #=> "987,43"

> arr = [1,2,3,4,5]     #=> [1, 2, 3, 4, 5] 
> arr.eat!              #=> [2, 3, 4, 5] 
> arr                   #=> [2, 3, 4, 5] 

That's better!

I know this is a cross post from here... but, I think one of the best Java books is Java Concurrency in Practice by Brian Goetz. A rather advanced book - but, it will wear well on your concurrent code and Java development in general.

Just set the position of the div and you may have to set the z-index.

ex.

div#map-div {
    position: absolute;
    left: 10px;
    top: 10px;
}
div#cover-div {
    position:absolute;
    left:10px;
    top: 10px;
    z-index:3;
}

Using appendEncodePath() could save you multiple lines than appendPath(), the following code snippet builds up this url: http://api.openweathermap.org/data/2.5/forecast/daily?zip=94043

Uri.Builder urlBuilder = new Uri.Builder();
urlBuilder.scheme("http");
urlBuilder.authority("api.openweathermap.org");
urlBuilder.appendEncodedPath("data/2.5/forecast/daily");
urlBuilder.appendQueryParameter("zip", "94043,us");
URL url = new URL(urlBuilder.build().toString());

Arriving a little late to this discussion but this is my contribution fwiw. I have an IList<Guid> OrderIds to be converted to a CSV string but following is generic and works unmodified with other types:

string csv = OrderIds.Aggregate(new StringBuilder(),
             (sb, v) => sb.Append(v).Append(","),
             sb => {if (0 < sb.Length) sb.Length--; return sb.ToString();});

Short and sweet, uses StringBuilder for constructing new string, shrinks StringBuilder length by one to remove last comma and returns CSV string.

I've updated this to use multiple Append()'s to add string + comma. From James' feedback I used Reflector to have a look at StringBuilder.AppendFormat(). Turns out AppendFormat() uses a StringBuilder to construct the format string which makes it less efficient in this context than just using multiple Appends()'s.

actually, your answer is not complete as the values also depend on the wrapping container. In case of relative or linear layouts, the values behave like this:

• EXACTLY match_parent is EXACTLY + size of the parent
• AT_MOST wrap_content results in an AT_MOST MeasureSpec
• UNSPECIFIED never triggered

In case of an horizontal scroll view, your code will work.

The following approach helped me.

Steps :

1.Go to the corresponding directory where the header file that is missing is located. (In my case,../include/unicode/coll.h was missing) and copy the directory location where the header file is located.(Copy till the include directory.)

2.Right click on your project in the Solution Explorer->Properties->Configuration Properties->VC++ Directories->Include Directories. Paste the copied path here.

3.This solved my problem.I hope this helps !

If anyone use WPF Modern UI,they cant use OnTabSelected event.but they can use SelectedSourceChanged event.

like this

<mui:ModernTab Layout="Tab" SelectedSourceChanged="ModernTab_SelectedSourceChanged" Background="Blue" AllowDrop="True" Name="tabcontroller" >

C# code is

private void ModernTab_SelectedSourceChanged(object sender, SourceEventArgs e)
    {
          var links = ((ModernTab)sender).Links;

          var link = this.tabcontroller.Links.FirstOrDefault(l => l.Source == e.Source);

          if (link != null) {
              var index = this.tabcontroller.Links.IndexOf(link);
              MessageBox.Show(index.ToString());
          }            
    }

Taken from http://forum.jquery.com/topic/multiple-versions-of-jquery-on-the-same-page:

• Original page loads his "jquery.versionX.js" -- $ and jQuery belong to versionX.
• You call your "jquery.versionY.js" -- now $ and jQuery belong to versionY, plus _$ and _jQuery belong to versionX.
• my_jQuery = jQuery.noConflict(true); -- now $ and jQuery belong to versionX, _$ and _jQuery are probably null, and my_jQuery is versionY.

At first if you want to hide div element with id = "abc" on load and then toggle between hide and show using a button with id = "btn" then,

$(document).ready(function() {
 $("#abc").hide(); 
  $("#btn").click(function() {
     $("#abc").toggle();
  });
});

You may use jQuery.grep():

var found_names = $.grep(names, function(v) {
    return v.name === "Joe" && v.age < 30;
});

Look at the widgets documentation. Basically it would look like:

q = forms.CharField(label='search', 
                    widget=forms.TextInput(attrs={'placeholder': 'Search'}))

More writing, yes, but the separation allows for better abstraction of more complicated cases.

You can also declare a widgets attribute containing a <field name> => <widget instance> mapping directly on the Meta of your ModelForm sub-class.

If you need a CakePHP Docker Container with MySQL, I have created a Docker image for that purpose! No need to worry about setting it up. It just works!

• GitHub: https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker
• DockerHub: https://hub.docker.com/r/marcellodesales/php-apache-cakephp-mysql/

Here's how I installed in Ubuntu-based image:

https://github.com/marcellodesales/php-apache-mysql-4-cakephp-docker/blob/master/Dockerfile#L8

RUN docker-php-ext-install mysql mysqli pdo pdo_mysql

Building and running your application is just a 2 step process (considering you are in the current directory of the app):

$ docker build -t myCakePhpApp .
$ docker run -ti myCakePhpApp

Now I have a much better solution that enables painless Vagrant upgrade. It is based on patched file.

The first line of a vagrantfile should be:

load "vagrantfile_ssh" if Vagrant::Util::Platform.windows?

And the patched vagrantfile_ssh file (originaly named ssh.rb) should exist in the same directory as vagrantfile. This is both elegant and functional.

Download the patched vagrantfile_ssh.

Here's one reason you may want to use one over the other - password retrieval.

If you only store a hash of a user's password, you can't offer a 'forgotten password' feature.

You can also overload the Function prototype:

// partially applies the specified arguments to a function, returning a new function
Function.prototype.curry = function( ) {
    var func = this;
    var slice = Array.prototype.slice;
    var appliedArgs = slice.call( arguments, 0 );

    return function( ) {
        var leftoverArgs = slice.call( arguments, 0 );
        return func.apply( this, appliedArgs.concat( leftoverArgs ) );
    };
};

// can do other fancy things:

// flips the first two arguments of a function
Function.prototype.flip = function( ) {
    var func = this;
    return function( ) {
        var first = arguments[0];
        var second = arguments[1];
        var rest = Array.prototype.slice.call( arguments, 2 );
        var newArgs = [second, first].concat( rest );

        return func.apply( this, newArgs );
    };
};

/*
e.g.

var foo = function( a, b, c, d ) { console.log( a, b, c, d ); }
var iAmA = foo.curry( "I", "am", "a" );
iAmA( "Donkey" );
-> I am a Donkey

var bah = foo.flip( );
bah( 1, 2, 3, 4 );
-> 2 1 3 4

Here is my solution, cobbled together from the range filter example in the datatables docs, and letting moment.js do the dirty work of comparing the dates.

HTML

<input 
    type="text" 
    id="min-date"
    class="date-range-filter"
    placeholder="From: yyyy-mm-dd">

<input 
    type="text" 
    id="max-date" 
    class="date-range-filter"
    placeholder="To: yyyy-mm-dd">

<table id="my-table">
    <thead>
        <tr>
            <th>ID</th>
            <th>Name</th>
            <th>Created At</th>
        </tr>
    </thead>
</table>

JS

Install Moment: npm install moment

// Assign moment to global namespace
window.moment = require('moment');

// Set up your table
table = $('#my-table').DataTable({
    // ... do your thing here.
});

// Extend dataTables search
$.fn.dataTable.ext.search.push(
    function( settings, data, dataIndex ) {
        var min  = $('#min-date').val();
        var max  = $('#max-date').val();
        var createdAt = data[2] || 0; // Our date column in the table

        if  ( 
                ( min == "" || max == "" )
                || 
                ( moment(createdAt).isSameOrAfter(min) && moment(createdAt).isSameOrBefore(max) ) 
            )
        {
            return true;
        }
        return false;
    }
);

// Re-draw the table when the a date range filter changes
$('.date-range-filter').change( function() {
    table.draw();
} );

Notes

• Using moment decouples the date comparison logic, and makes it easy to work with different formats. In my table, I used yyyy-mm-dd, but you could use mm/dd/yyyy as well. Be sure to reference moment's docs when parsing other formats, as you may need to modify what method you use.

Given

std::vector<Rule>& topPriorityRules;

The correct way to remove the first element of the referenced vector is

topPriorityRules.erase(topPriorityRules.begin());

which is exactly what you suggested.

Looks like i need to do iterator overloading.

There is no need to overload an iterator in order to erase first element of std::vector.

P.S. Vector (dynamic array) is probably a wrong choice of data structure if you intend to erase from the front.

You can use getattr

getattr(module, class_name)

to access the class. More complete code:

module = __import__(module_name)
class_ = getattr(module, class_name)
instance = class_()

As mentioned below, we may use importlib

import importlib
module = importlib.import_module(module_name)
class_ = getattr(module, class_name)
instance = class_()

The library called, Matrix supports so many features including mathematics operations, dumping and logging features, associative containers, multiple dimensions and etc.

Usage

its usage is similar to c++ arrays.

Matrix<int> A(1, 2);
Matrix<int> B(2, 3);
Matrix<int> result(1, 3);

A[0][0] = 7;
A[0][1] = 10;

B[0][0] = 1;
B[0][1] = 4;
B[0][2] = 2;
B[1][0] = 1;
B[1][1] = 2;
B[1][2] = 100;

result = A * B;

result.dump.matrix();

Result:

Matrix view:
-            -
| 17 48 1014 |
-            -

For the sake of completeness, let me mention that there are some places (on a Windows PC) to look for javaw.exe in case it is not found in the path: (Still Reimeus' suggestion should be your first attempt.)

1.
Java usually stores it's location in Registry, under the following key:
HKLM\Software\JavaSoft\Java Runtime Environement\<CurrentVersion>\JavaHome

2.
Newer versions of JRE/JDK, seem to also place a copy of javaw.exe in 'C:\Windows\System32', so one might want to check there too (although chances are, if it is there, it will be found in the path as well).

3.
Of course there are the "usual" install locations:

• 'C:\Program Files\Java\jre*\bin'
• 'C:\Program Files\Java\jdk*\bin'
• 'C:\Program Files (x86)\Java\jre*\bin'
• 'C:\Program Files (x86)\Java\jdk*\bin'

[Note, that for older versions of Windows (XP, Vista(?)), this will only help on english versions of the OS. Fortunately, on later version of Windows "Program Files" will point to the directory regardless of its "display name" (which is language-specific).]

A little while back, I wrote this piece of code to check for javaw.exe in the aforementioned places. Maybe someone finds it useful:

static protected String findJavaw() {
    Path pathToJavaw = null;
    Path temp;

    /* Check in Registry: HKLM\Software\JavaSoft\Java Runtime Environement\<CurrentVersion>\JavaHome */
    String keyNode = "HKLM\\Software\\JavaSoft\\Java Runtime Environment";

    executeCommand(new String[] {"REG", "QUERY", "\"" + keyNode + "\"", 
                                 "/v", "CurrentVersion"}, 
                   output);
    Pattern pattern = Pattern.compile("\\s*CurrentVersion\\s+\\S+\\s+(.*)$");
    for (String line : output) {
        Matcher matcher = pattern.matcher(line);
        if (matcher.find()) {
            keyNode += "\\" + matcher.group(1);
            List<String> output2 = new ArrayList<>();
            executeCommand(
                    new String[] {"REG", "QUERY", "\"" + keyNode + "\"", 
                                  "/v", "JavaHome"}, 
                    output2);
            Pattern pattern2 
                    = Pattern.compile("\\s*JavaHome\\s+\\S+\\s+(.*)$");

        try (DirectoryStream<Path> dirStream 
                = Files.newDirectoryStream(temp, "jdk*")) {
            for (Path path : dirStream) {
                temp = Paths.get(path.toString(), "jre", "bin", "javaw.exe");
                if (Files.exists(temp)) {
                    pathToJavaw = temp;
                    // Don't "break", in order to find the latest JDK version
                }                    
            }
            if (pathToJavaw != null) {
                return pathToJavaw.toString();
            }
        } catch (Exception ignored) {}
    }

    return "javaw.exe";   // Let's just hope it is in the path :)
}

Maybe, it will be helpful for someone
Recently I used this solution for my App
I am not sure that is a correct solution but it works fine.

this.state = {
    inputValue: "",
    isInputNotValid: false
}

handleInputValue = (evt) => {
    this.validationField(evt, "isInputNotValid", "inputValue");
}

validationField = (evt, isFieldNotValid, fieldValue ) => {
   if (evt.target.value && !isNaN(evt.target.value)) {
        this.setState({ 
            [isFieldNotValid]: false,
            [fieldValue]: evt.target.value,
        });
    } else {
        this.setState({ 
            [isFieldNotValid]: true,
            [fieldValue]: "",
        });
    }
}

<input className={this.state.isInputNotValid ? "error" : null} type="text" onChange="this.handleInputValue" />

The main idea, that state won't update till the condition isn't true and value will be empty.
Don't need to use onKeyPress, Down etc.,
also if you use these methods they aren't working on touch devices

For me, i make JavaScript redirection to another page to get rid of #_=_. The ideas below should work. :)

function redirect($url){
    echo "<script>window.location.href='{$url}?{$_SERVER["QUERY_STRING"]}'</script>";        
}

I made an installation guide for Egit on Eclipse so I thought I would share it.

1. INSTALL EGIT plugin in eclispe which is pretty easy. If EGit is missing in your Eclipse installation, you can install it via the Eclipse Update Manager via: Help ? Install new Software. EGit can be installed from the following URL: http://download.eclipse.org/egit/updates Under Eclipse Git Team Provider, tick ONLY "Eclipse EGit" and then download the plugin.

2. CONNECT TO YOUR LOCAL REPOSITORY. I right clicked on the project, selected "team > share project" and then ticked "use or create repository"

3. GIT IGNORE. Mark the "bin" folder as "ignored by Git", either by right-clicking on it and selecting Team > Ignore or by creating a .gitignore file. My file was generated for me, I just had to make it visible. Here's how in eclipse: In your package explorer, pull down the menu and select "Filters ...". You can adjust what types of files are shown/hidden there.

4. IDENTIFY YOURSELF. Click Preferences > Team > Git > Configuration and make sure your name & email are there so we know which user committed/pushed what.

NOW YOU ARE READY TO ADD/COMMIT/PUSH/PULL files with the plugin!

If you like GUIs, you can use gitk:

1. start gitk with:

   gitk /path/to/file
   

2. Choose the revision in the top part of the screen, e.g. by description or date. By default, the lower part of the screen shows the diff for that revision, (corresponding to the "patch" radio button).

3. To see the file for the selected revision:

   • Click on the "tree" radio button. This will show the root of the file tree at that revision.
   • Drill down to your file.

Edit: I missed the multi-dimensional aspect of this question, so I'm leaving this here in case it helps people compare one-dimensional arrays

It's an old question, but I was having issues with the speed of using .sort() or sortBy(), so I used this instead:

function arraysContainSameStrings(array1: string[], array2: string[]): boolean {
  return (
    array1.length === array2.length &&
    array1.every((str) => array2.includes(str)) &&
    array2.every((str) => array1.includes(str))
  )
}

It was intended to fail fast, and for my purposes works fine.

Try this

<?php 
echo '<i style="color:blue;font-size:30px;font-family:calibri ;">
      hello php color </i> ';
//we cannot use double quote after echo , it must be single quote.
?>

You can't. However, you CAN use a transaction and have both of them be contained within one transaction.

START TRANSACTION;
INSERT INTO table1 VALUES ('1','2','3');
INSERT INTO table2 VALUES ('bob','smith');
COMMIT;

http://dev.mysql.com/doc/refman/5.1/en/commit.html

Efficiency aside, I rarely find myself wishing for declarative collection creation outside of unit tests. I do believe that the double brace syntax is very readable.

Another way to achieve the declarative construction of lists specifically is to use Arrays.asList(T ...) like so:

List<String> aList = Arrays.asList("vanilla", "strawberry", "chocolate");

The limitation of this approach is of course that you cannot control the specific type of list to be generated.

You would need to have an instance of ClassA within ClassB or have ClassB inherit ClassA

class ClassA {
    public function getName() {
      echo $this->name;
    }
}

class ClassB extends ClassA {
    public function getName() {
      parent::getName();
    }
}

Without inheritance or an instance method, you'd need ClassA to have a static method

class ClassA {
  public static function getName() {
    echo "Rawkode";
  }
}

--- other file ---

echo ClassA::getName();

If you're just looking to call the method from an instance of the class:

class ClassA {
  public function getName() {
    echo "Rawkode";
  }
}

--- other file ---

$a = new ClassA();
echo $a->getName();

Regardless of the solution you choose, require 'ClassA.php is needed.

15841:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:188:
...
SSL handshake has read 0 bytes and written 121 bytes

This is a handshake failure. The other side closes the connection without sending any data ("read 0 bytes"). It might be, that the other side does not speak SSL at all. But I've seen similar errors on broken SSL implementation, which do not understand newer SSL version. Try if you get a SSL connection by adding -ssl3 to the command line of s_client.

These are mostly equivalent, but import * has some restrictions that import ... = require doesn't.

import * as creates an identifier that is a module object, emphasis on object. According to the ES6 spec, this object is never callable or newable - it only has properties. If you're trying to import a function or class, you should use

import express = require('express');

or (depending on your module loader)

import express from 'express';

Attempting to use import * as express and then invoking express() is always illegal according to the ES6 spec. In some runtime+transpilation environments this might happen to work anyway, but it might break at any point in the future without warning, which will make you sad.

@ComponentScan uses string array, like this:

@ComponentScan({"com.my.package.first","com.my.package.second"})

When you provide multiple package names in only one string, Spring interprets this as one package name, and thus can't find it.

<?php
$args     = array( 'post_type' => 'product', 'category' => 34, 'posts_per_page' => -1 );
$products = get_posts( $args ); 
?>

This should grab all the products you want, I may have the post type wrong though I can't quite remember what woo-commerce uses for the post type. It will return an array of products

You could use

Calendar cal = Calendar.getInstance();
cal.setTime(beginupd);
long millis = cal.getTimeInMillis();

This is how I solved this issue:

1. git pull origin master
2. git push origin master

This usually happens when your remote branch is not updated. And after this if you get an error like "Please enter a commit message" Refer to this ( For me xiaohu Wang answer worked :) )

Set this as your view background

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <stroke
        android:width="1dp"
        android:color="#78d9ff"/>
</shape>

For solid circle use:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid
        android:color="#48b3ff"/>
</shape>

Solid with stroke:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="#199fff"/>
    <stroke
        android:width="2dp"
        android:color="#444444"/>
</shape>

Note: To make the oval shape appear as a circle, in these examples, either your view that you are using this shape as its background should be a square or you have to set the height and width properties of the shape tag to an equal value.

Please be aware that the examples for icon file path tend to assume that main.js is under the base directory. If the file is not in the base directory of the app, the path specification must account for that fact.

For example, if the main.js is under the src/ subdirectory, and the icon is under assets/icons/, this icon path specification will work:

icon: __dirname + "../assets/icons/icon.png"

You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:

• full path from file input using jquery
• How to get the file path from HTML input form in Firefox 3

In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file" field, ostensibly for backward compatibility reasons.

• http://lists.whatwg.org/htdig.cgi/whatwg-whatwg.org/2009-March/018981.html
• The Mystery of c:\fakepath Unveiled

So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.

You should be able to do this with a pretty standard DAO recordset loop. You can see some examples at the following links:
http://msdn.microsoft.com/en-us/library/bb243789%28v=office.12%29.aspx
http://www.granite.ab.ca/access/email/recordsetloop.htm

My own standard loop looks something like this:

Dim rs As DAO.Recordset
Set rs = CurrentDb.OpenRecordset("SELECT * FROM Contacts")

'Check to see if the recordset actually contains rows
If Not (rs.EOF And rs.BOF) Then
    rs.MoveFirst 'Unnecessary in this case, but still a good habit
    Do Until rs.EOF = True
        'Perform an edit
        rs.Edit
        rs!VendorYN = True
        rs("VendorYN") = True 'The other way to refer to a field
        rs.Update

        'Save contact name into a variable
        sContactName = rs!FirstName & " " & rs!LastName

        'Move to the next record. Don't ever forget to do this.
        rs.MoveNext
    Loop
Else
    MsgBox "There are no records in the recordset."
End If

MsgBox "Finished looping through records."

rs.Close 'Close the recordset
Set rs = Nothing 'Clean up

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

If you are planning to use the code in a production web application code,
using any web framework like Django/Flask, use projects like envparse, using it you can read the value as your defined type.

from envparse import env
# will read WHITE_LIST=hello,world,hi to white_list = ["hello", "world", "hi"]
white_list = env.list("WHITE_LIST", default=[]) 
# Perfect for reading boolean
DEBUG = env.bool("DEBUG", default=False)

NOTE: kennethreitz's autoenv is a recommended tool for making project specific environment variables, please note that those who are using autoenv please keep the .env file private (inaccessible to public)

Here's what i do to FORCE UNLOCK FOR some locked tables in MySQL

1) Enter MySQL

mysql -u your_user -p

2) Let's see the list of locked tables

mysql> show open tables where in_use>0;

3) Let's see the list of the current processes, one of them is locking your table(s)

mysql> show processlist;

4) Let's kill one of these processes

mysql> kill put_process_id_here;

If using GitHub on Windows:

1. Make changes locally.
2. Open GitHub, switch to local repositories, double click repository.
3. Switch the branch(near top of window) to the branch that you created the pull request from(i.e. the branch on your fork side of the compare)
4. Should see option to enter commit comment on right and commit changes to your local repo.
5. Click sync on top, which among other things, pushes your commit from local to your remote fork on GitHub.
6. The pull request will be updated automatically with the additional commits. This is because the pulled request represents a diff with your fork's branch. If you go to the pull request page(the one where you and others can comment on your pull request) then the Commits tab should have your additional commit(s).

This is why, before you start making changes of your own, that you should create a branch for each set of changes you plan to put into a pull request. That way, once you make the pull request, you can then make another branch and continue work on some other task/feature/bugfix without affecting the previous pull request.

malloc does not allocate on specific boundaries, so it must be assumed that it allocates on a byte boundary.

The returned pointer can then not be used if converted to any other type, since accessing that pointer will probably produce a memory access violation by the CPU, and the application will be immediately shut down.

I've been working on a function to work within a library for a client, and have been having a lot of trouble keeping the UI responsive during the sorts (even with only a few hundred results).

The function has to resort the entire table each AJAX pagination, as new data may require injection further up. This is what I had so far:

• jQuery library required.
• table is the ID of the table being sorted.
• The table attributes sort-attribute, sort-direction and the column attribute column are all pre-set.

Using some of the details above I managed to improve performance a bit.

function sorttable(table) {
    var context = $('#' + table), tbody = $('#' + table + ' tbody'), sortfield = $(context).data('sort-attribute'), c, dir = $(context).data('sort-direction'), index = $(context).find('thead th[data-column="' + sortfield + '"]').index();
    if (!sortfield) {
        sortfield = $(context).data('id-attribute');
    };
    switch (dir) {
        case "asc":
            tbody.find('tr').sort(function (a, b) {
                var sortvala = parseFloat($(a).find('td:eq(' + index + ')').text());
                var sortvalb = parseFloat($(b).find('td:eq(' + index + ')').text());
                // if a < b return 1
                return sortvala < sortvalb ? 1
                       // else if a > b return -1
                       : sortvala > sortvalb ? -1
                       // else they are equal - return 0    
                       : 0;
            }).appendTo(tbody);
            break;
        case "desc":
        default:
            tbody.find('tr').sort(function (a, b) {
                var sortvala = parseFloat($(a).find('td:eq(' + index + ')').text());
                var sortvalb = parseFloat($(b).find('td:eq(' + index + ')').text());
                // if a < b return 1
                return sortvala > sortvalb ? 1
                       // else if a > b return -1
                       : sortvala < sortvalb ? -1
                       // else they are equal - return 0    
                       : 0;
            }).appendTo(tbody);
        break;
  }

In principle the code works perfectly, but it's painfully slow... are there any ways to improve performance?

The reason your original dataframe does not update is because chained indexing may cause you to modify a copy rather than a view of your dataframe. The docs give this advice:

When setting values in a pandas object, care must be taken to avoid what is called chained indexing.

You have a few alternatives:-

loc + Boolean indexing

loc may be used for setting values and supports Boolean masks:

df.loc[df['my_channel'] > 20000, 'my_channel'] = 0

mask + Boolean indexing

You can assign to your series:

df['my_channel'] = df['my_channel'].mask(df['my_channel'] > 20000, 0)

Or you can update your series in place:

df['my_channel'].mask(df['my_channel'] > 20000, 0, inplace=True)

np.where + Boolean indexing

You can use NumPy by assigning your original series when your condition is not satisfied; however, the first two solutions are cleaner since they explicitly change only specified values.

df['my_channel'] = np.where(df['my_channel'] > 20000, 0, df['my_channel'])

You need a section in your file:

[My Section]
path1 = D:\test1\first
path2 = D:\test2\second
path3 = D:\test2\third

Then, read the properties:

import ConfigParser

config = ConfigParser.ConfigParser()
config.readfp(open(r'abc.txt'))
path1 = config.get('My Section', 'path1')
path2 = config.get('My Section', 'path2')
path3 = config.get('My Section', 'path3')

When using the $array.Add()-method, you're trying to add the element into the existing array. An array is a collection of fixed size, so you will receive an error because it can't be extended.

$array += $element creates a new array with the same elements as old one + the new item, and this new larger array replaces the old one in the $array-variable

You can use the += operator to add an element to an array. When you use it, Windows PowerShell actually creates a new array with the values of the original array and the added value. For example, to add an element with a value of 200 to the array in the $a variable, type:

    $a += 200

Source: about_Arrays

+= is an expensive operation, so when you need to add many items you should try to add them in as few operations as possible, ex:

$arr = 1..3    #Array
$arr += (4..5) #Combine with another array in a single write-operation

$arr.Count
5

If that's not possible, consider using a more efficient collection like List or ArrayList (see the other answer).

MacPorts is another package manager for OS X:.

Installation instructions are at The MacPorts Project -- Download & Installation after which one issues sudo port install pythonXX, where XX is 27 or 35.

I just discovered, after a bit of frustration, that if you're using PairNIC, all you have to do is enable the "Web Forwarding" setting under "Custom DNS" and supply the username.github.io/project address and it will automatically set up both the apex and subdomain records for you. It appears to do exactly what's suggested in the accepted answer. However, it won't let you do the exact same thing by manually adding records. Very strange. Anyway, it took me a while to figure that out, so I thought I'd share to save everyone else the trouble.

right-click on the project > Properties > Java Editor > Save Actions

You're already doing it!

save() will check if something in the model has changed. If it hasn't it won't run a db query.

Here's the relevant part of code in Illuminate\Database\Eloquent\Model@performUpdate:

protected function performUpdate(Builder $query, array $options = [])
{
    $dirty = $this->getDirty();

    if (count($dirty) > 0)
    {
        // runs update query
    }

    return true;
}

The getDirty() method simply compares the current attributes with a copy saved in original when the model is created. This is done in the syncOriginal() method:

public function __construct(array $attributes = array())
{
    $this->bootIfNotBooted();

    $this->syncOriginal();

    $this->fill($attributes);
}

public function syncOriginal()
{
    $this->original = $this->attributes;

    return $this;
}

If you want to check if the model is dirty just call isDirty():

if($product->isDirty()){
    // changes have been made
}

Or if you want to check a certain attribute:

if($product->isDirty('price')){
    // price has changed
}

You need to create new rails application first. Run

rails new mebay
cd mebay
bundle install
rails generate model ...

And try to find Rails 3 tutorial, there are a lot of changes since 2.1 Guides (http://guides.rubyonrails.org/getting_started.html) are good start point.

The mentioned package/classes are not present in the compiletime classpath. Basically, Java has no idea what you're talking about when you say to import this and that. It can't find them in the classpath.

It's part of Apache Commons FileUpload. Just download the JAR and drop it in /WEB-INF/lib folder of the webapp project and this error should disappear. Don't forget to do the same for Apache Commons IO, that's where FileUpload depends on, otherwise you will get the same problem during runtime.

Unrelated to the concrete problem, I see that you're using Tomcat 7, which is a Servlet 3.0 compatible container. Do you know that you can just use the new request.getPart() method to obtain the uploaded file without the need for the whole Commons FileUpload stuff? Just add @MultipartConfig annotation to the servlet class so that you can use it. See also How to upload files to server using JSP/Servlet?

For Debian Jessie (which is the current default for the PHP image on Docker Hub):

apt-get install --yes zip unzip php-pclzip

You can omit the --yes, but it's useful when you're RUN-ing it in a Dockerfile.

To build on other answers above, in case you have a Spring boot REST service application (not Spring MVC) with Spring security, then enabling CORS via Spring security is enough (if you use Spring MVC then using a WebMvcConfigurer bean as mentioned by Yogen could be the way to go as Spring security will delegate to the CORS definition mentioned therein)

So you need to have a security config that does the following:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Override
protected void configure(HttpSecurity http) throws Exception {
    //other http security config
    http.cors().configurationSource(corsConfigurationSource());
}

//This can be customized as required
CorsConfigurationSource corsConfigurationSource() {
    CorsConfiguration configuration = new CorsConfiguration();
    List<String> allowOrigins = Arrays.asList("*");
    configuration.setAllowedOrigins(allowOrigins);
    configuration.setAllowedMethods(singletonList("*"));
    configuration.setAllowedHeaders(singletonList("*"));
    //in case authentication is enabled this flag MUST be set, otherwise CORS requests will fail
    configuration.setAllowCredentials(true);
    UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
    source.registerCorsConfiguration("/**", configuration);
    return source;
}

}

This link has more information on the same: https://docs.spring.io/spring-security/site/docs/current/reference/htmlsingle/#cors

Note:

1. Enabling CORS for all origins (*) for a prod deployed application may not always be a good idea.
2. CSRF can be enabled via the Spring HttpSecurity customization without any issues
3. In case you have authentication enabled in the app with Spring (via a UserDetailsService for example) then the configuration.setAllowCredentials(true); must be added

Tested for Spring boot 2.0.0.RELEASE (i.e., Spring 5.0.4.RELEASE and Spring security 5.0.3.RELEASE)

These are the vendor-prefixed properties offered by the relevant rendering engines (-webkit for Chrome, Safari; -moz for Firefox, -o for Opera, -ms for Internet Explorer). Typically they're used to implement new, or proprietary CSS features, prior to final clarification/definition by the W3.

This allows properties to be set specific to each individual browser/rendering engine in order for inconsistencies between implementations to be safely accounted for. The prefixes will, over time, be removed (at least in theory) as the unprefixed, the final version, of the property is implemented in that browser.

To that end it's usually considered good practice to specify the vendor-prefixed version first and then the non-prefixed version, in order that the non-prefixed property will override the vendor-prefixed property-settings once it's implemented; for example:

.elementClass {
    -moz-border-radius: 2em;
    -ms-border-radius: 2em;
    -o-border-radius: 2em;
    -webkit-border-radius: 2em;
    border-radius: 2em;
}

Specifically, to address the CSS in your question, the lines you quote:

-webkit-column-count: 3;
-webkit-column-gap: 10px;
-webkit-column-fill: auto;

Apparently you can use this trick.

<title> My title</title>

That icon-alike is actually a text.

I normally end up creating a single conn.php file that has my database connections. Then i include that file in all files that require database queries.

Key Point: Add both http://localhost and http://localhost:port_number to the Authorized JavaScript origins box for local tests or development.

Answered here: Convert an image to grayscale in HTML/CSS

You don't even need to use two images which sounds like a pain or an image manipulation library, you can do it with cross browser support (current versions) and just use CSS. This is a progressive enhancement approach which just falls back to color versions on older browsers:

img {
  filter: url(filters.svg#grayscale);
  /* Firefox 3.5+ */
  filter: gray;
  /* IE6-9 */
  -webkit-filter: grayscale(1);
  /* Google Chrome & Safari 6+ */
}
img:hover {
  filter: none;
  -webkit-filter: none;
}

and filters.svg file like this:

<svg xmlns="http://www.w3.org/2000/svg">
  <filter id="grayscale">
    <feColorMatrix type="matrix" values="0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0.3333 0.3333 0.3333 0 0 0 0 0 1 0" />
  </filter>
</svg>

The answer, as given, is to use format-patch but since the question was how to cherry-pick from another folder, here is a piece of code to do just that:

$ git --git-dir=../<some_other_repo>/.git \
format-patch -k -1 --stdout <commit SHA> | \
git am -3 -k

(explanation from @cong ma)

The git format-patch command creates a patch from some_other_repo's commit specified by its SHA (-1 for one single commit alone). This patch is piped to git am, which applies the patch locally (-3 means trying the three-way merge if the patch fails to apply cleanly). Hope that explains.

If you don't want to bother with the keystore file, then just remove the package altogether for all users.

Connect your device with Mac/PC and run adb uninstall <package>

Worked for me.

I am just wondering why to use some libraries for JWT token decoding and verification at all.

Encoded JWT token can be created using following pseudocode

var headers = base64URLencode(myHeaders);
var claims = base64URLencode(myClaims);
var payload = header + "." + claims;

var signature = base64URLencode(HMACSHA256(payload, secret));

var encodedJWT = payload + "." + signature;

It is very easy to do without any specific library. Using following code:

using System;
using System.Text;
using System.Security.Cryptography;

public class Program
{   
    // More info: https://stormpath.com/blog/jwt-the-right-way/
    public static void Main()
    {           
        var header = "{\"typ\":\"JWT\",\"alg\":\"HS256\"}";
        var claims = "{\"sub\":\"1047986\",\"email\":\"[email protected]\",\"given_name\":\"John\",\"family_name\":\"Doe\",\"primarysid\":\"b521a2af99bfdc65e04010ac1d046ff5\",\"iss\":\"http://example.com\",\"aud\":\"myapp\",\"exp\":1460555281,\"nbf\":1457963281}";

        var b64header = Convert.ToBase64String(Encoding.UTF8.GetBytes(header))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");
        var b64claims = Convert.ToBase64String(Encoding.UTF8.GetBytes(claims))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");

        var payload = b64header + "." + b64claims;
        Console.WriteLine("JWT without sig:    " + payload);

        byte[] key = Convert.FromBase64String("mPorwQB8kMDNQeeYO35KOrMMFn6rFVmbIohBphJPnp4=");
        byte[] message = Encoding.UTF8.GetBytes(payload);

        string sig = Convert.ToBase64String(HashHMAC(key, message))
            .Replace('+', '-')
            .Replace('/', '_')
            .Replace("=", "");

        Console.WriteLine("JWT with signature: " + payload + "." + sig);        
    }

    private static byte[] HashHMAC(byte[] key, byte[] message)
    {
        var hash = new HMACSHA256(key);
        return hash.ComputeHash(message);
    }
}

The token decoding is reversed version of the code above.To verify the signature you will need to the same and compare signature part with calculated signature.

UPDATE: For those how are struggling how to do base64 urlsafe encoding/decoding please see another SO question, and also wiki and RFCs

I was getting this error

Error:Execution failed for task ':app:preDebugAndroidTestBuild'. Conflict with dependency 'com.android.support:support-annotations' in project ':app'. Resolved versions for app (26.1.0) and test app (27.1.1) differ. See https://d.android.com/r/tools/test-apk-dependency-conflicts.html for details.

I was having following dependencies in my build.gradle file under Gradle Scripts

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'
implementation 'com.android.support:support-vector-drawable:26.1.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

So, I resolved it by commenting the following dependencies

testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

So my dependencies look like this

dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:support-v4:26.1.0'

//testImplementation 'junit:junit:4.12'
//androidTestImplementation 'com.android.support.test:runner:1.0.2'
//androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

Hope it helps!

If you're able to control the xml file, try adding a bit more information to the beginning of the file:

<?xml version="1.0" encoding="UTF-16" standalone="no"?>

static void printRepeating(int []arr, int size) { int i;

    Console.Write("The repeating" +  
                   " elements are : "); 

    for (i = 0; i < size; i++) 
    { 
        if (arr[ Math.Abs(arr[i])] >= 0) 
            arr[ Math.Abs(arr[i])] = 
                -arr[ Math.Abs(arr[i])]; 
        else
            Console.Write(Math.Abs(arr[i]) + " "); 
    }          
}  

/q isn't a valid parameter. /y: Suppresses prompting to confirm overwriting

Also ..\txt means directory txt under the parent directory, not the root directory. The root directory would be: \ And please mention the error you get

Try:

move files\*.txt \ 

Edit: Try:

move \files\*.txt \ 

Edit 2:

move C:\files\*.txt C:\txt

This is caused by the limited support for the MP4 format within the video tag in Firefox. Support was not added until Firefox 21, and it is still limited to Windows 7 and above. The main reason for the limited support revolves around the royalty fee attached to the mp4 format.

Check out Supported media formats and Media formats supported by the audio and video elements directly from the Mozilla crew or the following blog post for more information:

In Eclipse, Go to your class, Right click->source->Generate toString();

It will override the toString() method and will print the object of that class.

I don't know if it's wise to do so, but you can just write

"filesizecounter: " + $filesizecounter

And it should output:

filesizecounter: value

You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});

I've been to this post about 10 times now and I just wanted to leave my two cents here. You can just unmount it conditionally.

if (renderMyComponent) {
  <MyComponent props={...} />
}

All you have to do is remove it from the DOM in order to unmount it.

As long as renderMyComponent = true, the component will render. If you set renderMyComponent = false, it will unmount from the DOM.

From Linux Change Default User Home Directory While Adding A New User:

Simply open this file using a text editor, type:

vi /etc/default/useradd

The default home directory defined by HOME variable, find line that read as follows:

HOME=/home

Replace with:

HOME=/iscsi/user

Save and close the file. Now you can add user using regular useradd command:

# useradd vivek
# passwd vivek

Verify user information:

# finger vivek

I found an issue with someone using PDO and the answer was to use this for the PDO connection string:

$pdo = new PDO(
    'mysql:host=mysql.example.com;dbname=example_db',
    "username",
    "password",
    array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));

The site I took this from is down, but I was able to get it using the Google cache, luckily.

What about this alternative idea :

• two have two executors :
  • one for :
    • submitting the task, without caring about the timeout of the task
    • adding the Future resulted and the time when it should end to an internal structure
  • one for executing an internal job which is checking the internal structure if some tasks are timeout and if they have to be cancelled.

Small sample is here :

public class AlternativeExecutorService 
{

private final CopyOnWriteArrayList<ListenableFutureTask> futureQueue       = new CopyOnWriteArrayList();
private final ScheduledThreadPoolExecutor                scheduledExecutor = new ScheduledThreadPoolExecutor(1); // used for internal cleaning job
private final ListeningExecutorService                   threadExecutor    = MoreExecutors.listeningDecorator(Executors.newFixedThreadPool(5)); // used for
private ScheduledFuture scheduledFuture;
private static final long INTERNAL_JOB_CLEANUP_FREQUENCY = 1000L;

public AlternativeExecutorService()
{
    scheduledFuture = scheduledExecutor.scheduleAtFixedRate(new TimeoutManagerJob(), 0, INTERNAL_JOB_CLEANUP_FREQUENCY, TimeUnit.MILLISECONDS);
}

public void pushTask(OwnTask task)
{
    ListenableFuture<Void> future = threadExecutor.submit(task);  // -> create your Callable
    futureQueue.add(new ListenableFutureTask(future, task, getCurrentMillisecondsTime())); // -> store the time when the task should end
}

public void shutdownInternalScheduledExecutor()
{
    scheduledFuture.cancel(true);
    scheduledExecutor.shutdownNow();
}

long getCurrentMillisecondsTime()
{
    return Calendar.getInstance().get(Calendar.MILLISECOND);
}

class ListenableFutureTask
{
    private final ListenableFuture<Void> future;
    private final OwnTask                task;
    private final long                   milliSecEndTime;

    private ListenableFutureTask(ListenableFuture<Void> future, OwnTask task, long milliSecStartTime)
    {
        this.future = future;
        this.task = task;
        this.milliSecEndTime = milliSecStartTime + task.getTimeUnit().convert(task.getTimeoutDuration(), TimeUnit.MILLISECONDS);
    }

    ListenableFuture<Void> getFuture()
    {
        return future;
    }

    OwnTask getTask()
    {
        return task;
    }

    long getMilliSecEndTime()
    {
        return milliSecEndTime;
    }
}

class TimeoutManagerJob implements Runnable
{
    CopyOnWriteArrayList<ListenableFutureTask> getCopyOnWriteArrayList()
    {
        return futureQueue;
    }

    @Override
    public void run()
    {
        long currentMileSecValue = getCurrentMillisecondsTime();
        for (ListenableFutureTask futureTask : futureQueue)
        {
            consumeFuture(futureTask, currentMileSecValue);
        }
    }

    private void consumeFuture(ListenableFutureTask futureTask, long currentMileSecValue)
    {
        ListenableFuture<Void> future = futureTask.getFuture();
        boolean isTimeout = futureTask.getMilliSecEndTime() >= currentMileSecValue;
        if (isTimeout)
        {
            if (!future.isDone())
            {
                future.cancel(true);
            }
            futureQueue.remove(futureTask);
        }
    }
}

class OwnTask implements Callable<Void>
{
    private long     timeoutDuration;
    private TimeUnit timeUnit;

    OwnTask(long timeoutDuration, TimeUnit timeUnit)
    {
        this.timeoutDuration = timeoutDuration;
        this.timeUnit = timeUnit;
    }

    @Override
    public Void call() throws Exception
    {
        // do logic
        return null;
    }

    public long getTimeoutDuration()
    {
        return timeoutDuration;
    }

    public TimeUnit getTimeUnit()
    {
        return timeUnit;
    }
}
}

hash_map is a non-standard extension. unordered_map is part of std::tr1, and will be moved into the std namespace for C++0x. http://en.wikipedia.org/wiki/Unordered_map_%28C%2B%2B%29

Unfortunately none of the solutions worked for me. I used Internet Explorer 8 on Windows 7. When I was looking for a solution, I found the settings about login information in the control panel. So I added a new entry under the certificate based information with the address of my server and I chose my prefered certificate.

After a clear of the SSL cache in Internet Explorer 8 I just refreshed the site and the right certificate was sent to the server.

This isn't the solution which I wanted, but it works.

You can list the tags on remote repository with ls-remote, and then check if it's there. Supposing the remote reference name is origin in the following.

git ls-remote --tags origin

And you can list tags local with tag.

git tag

You can compare the results manually or in script.

Try following code will Add one day to current date

select DateAdd(day, 1, GetDate())

And in the same way can use Year, Month, Hour, Second etc. instead of day in the same function

It is not good idea because you just temporary redirect user to https and browser doesn't save this redirect.

You describe task for web-server (apache, nginx etc) http 301, http 302

Rather than going into the AndroidManifest, you could just do this:

screenOrientation = getResources().getConfiguration().orientation;
getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);
... AsyncTask

screenOrientation = getResources().getConfiguration().orientation;


@Override
protected void onPostExecute(String things) {
    context.setRequestedOrientation(PlayListFragment.screenOrientation);
    or 
    context.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
}

The only drawback here is that it requires API level 18 or higher. So basically this is the tip of the spear.

I had same error and I change the setting from release to debug and the problem resolved..

listOfSomething.Clear();
listOfSomething.Add("first");
collection.Add(listOfSomething);

You are clearing the list here and adding one element ("first"), the 1st reference of listOfSomething is updated as well sonce both reference the same object, so when you access the second element myList.get(1) (which does not exist anymore) you get the null.

Notice both collection.Add(listOfSomething); save two references to the same arraylist object.

You need to create two different instances for two elements:

ArrayList<ArrayList<String>> collection = new ArrayList<ArrayList<String>>();

ArrayList<String> listOfSomething1 = new ArrayList<String>();
listOfSomething1.Add("first");
listOfSomething1.Add("second");

ArrayList<String> listOfSomething2 = new ArrayList<String>();
listOfSomething2.Add("first");

collection.Add(listOfSomething1);    
collection.Add(listOfSomething2);
