This solved my problem.

 const url = 'mongodb://localhost:27017';

 const client = new MongoClient(url, {useUnifiedTopology: true});

This error is due to mongo driver dropping the connection for any reason (server was down for example).

By default mongoose will try to reconnect for 30 seconds then stop retrying and throw errors forever until restarted.

You can change this by editing these 2 fields in the connection options

mongoose.connect(uri, 
    { server: { 
        // sets how many times to try reconnecting
        reconnectTries: Number.MAX_VALUE,
        // sets the delay between every retry (milliseconds)
        reconnectInterval: 1000 
        } 
    }
);

connection options documentation

#1 Re-install uuid-ossp extention in an exact schema:

SET search_path TO public;
DROP EXTENSION IF EXISTS "uuid-ossp";

CREATE EXTENSION "uuid-ossp" SCHEMA public;

If this is a fresh installation you can skip SET and DROP. Credits to @atomCode (details)

After this, you should see uuid_generate_v4() function IN THE RIGHT SCHEMA (when execute \df query in psql command-line prompt).

#2 Use fully-qualified names (with schemaname. qualifier):

CREATE TABLE public.my_table (
    id uuid DEFAULT public.uuid_generate_v4() NOT NULL,

In my case these sort of issues were solved using defer https://developer.mozilla.org/en/docs/Web/HTML/Element/script

<script src="<your file>.js" defer></script>

You need to take into account browsers's support of this option though (I haven't seen problems)

While the existing answers have given solutions to solve the issue and the second half of the question, they do not provide an answer to the self discovery aspect of the first half of the question that is in bold:

"How can I see which variable causes memory overhead...?"

It may not have been as robust 3 years ago, but the Chrome Developer Tools "Profiles" section is now quite powerful and feature rich. The Chrome team has an insightful article on using it and thus also how garbage collection (GC) works in javascript, which is at the core of this question.

Since delete is basically the root of the currently accepted answer by Yochai Akoka, it's important to remember what delete does. It's irrelevant if not combined with the concepts of how GC works in the next two answers: if there's an existing reference to an object it's not cleaned up. The answers are more correct, but probably not as appreciated because they require more thought than just writing 'delete'. Yes, one possible solution may be to use delete, but it won't matter if there's another reference to the memory leak.

Another answer appropriately mentions circular references and the Chrome team documentation can provide much more clarity as well as the tools to verify the cause.

Since delete was mentioned here, it also may be useful to provide the resource Understanding Delete. Although it does not get into any of the actual solution which is really related to javascript's garbage collector.

For those using the VSCode text editor, consider the Git History Extension by D. Jayamanne:

Hi i tried this it is working.

$("#change_align").css({"margin-top":"-39px","margin-right":"0px","margin-bottom":"0px","margin-left":"719px"});

I'm guessing from your last question, asked 20 minutes before this one, that you are trying to parse (read and convert) the XML found through using GeoNames' FindNearestAddress.

If your XML is in a string variable called txt and looks like this:

<address>
  <street>Roble Ave</street>
  <mtfcc>S1400</mtfcc>
  <streetNumber>649</streetNumber>
  <lat>37.45127</lat>
  <lng>-122.18032</lng>
  <distance>0.04</distance>
  <postalcode>94025</postalcode>
  <placename>Menlo Park</placename>
  <adminCode2>081</adminCode2>
  <adminName2>San Mateo</adminName2>
  <adminCode1>CA</adminCode1>
  <adminName1>California</adminName1>
  <countryCode>US</countryCode>
</address>

Then you can parse the XML with Javascript DOM like this:

if (window.DOMParser)
{
    parser = new DOMParser();
    xmlDoc = parser.parseFromString(txt, "text/xml");
}
else // Internet Explorer
{
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
    xmlDoc.async = false;
    xmlDoc.loadXML(txt);
}

And get specific values from the nodes like this:

//Gets house address number
xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue;

//Gets Street name
xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue;

//Gets Postal Code
xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue;

JSFiddle

Feb. 2019 edit:

In response to @gaugeinvariante's concerns about xml with Namespace prefixes. Should you have a need to parse xml with Namespace prefixes, everything should work almost identically:

NOTE: this will only work in browsers that support xml namespace prefixes such as Microsoft Edge

// XML with namespace prefixes 's', 'sn', and 'p' in a variable called txt_x000D_
txt = `_x000D_
<address xmlns:p='example.com/postal' xmlns:s='example.com/street' xmlns:sn='example.com/streetNum'>_x000D_
  <s:street>Roble Ave</s:street>_x000D_
  <sn:streetNumber>649</sn:streetNumber>_x000D_
  <p:postalcode>94025</p:postalcode>_x000D_
</address>`;_x000D_
_x000D_
//Everything else the same_x000D_
if (window.DOMParser)_x000D_
{_x000D_
    parser = new DOMParser();_x000D_
    xmlDoc = parser.parseFromString(txt, "text/xml");_x000D_
}_x000D_
else // Internet Explorer_x000D_
{_x000D_
    xmlDoc = new ActiveXObject("Microsoft.XMLDOM");_x000D_
    xmlDoc.async = false;_x000D_
    xmlDoc.loadXML(txt);_x000D_
}_x000D_
_x000D_
//The prefix should not be included when you request the xml namespace_x000D_
//Gets "streetNumber" (note there is no prefix of "sn"_x000D_
console.log(xmlDoc.getElementsByTagName("streetNumber")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Street name_x000D_
console.log(xmlDoc.getElementsByTagName("street")[0].childNodes[0].nodeValue);_x000D_
_x000D_
//Gets Postal Code_x000D_
console.log(xmlDoc.getElementsByTagName("postalcode")[0].childNodes[0].nodeValue);

I know this is an old question, but just in case you are trying to do the same thing in ASP.NET Core, here is how you can create the UrlHelper inside an action:

var urlHelper = new UrlHelper(this.ControllerContext);

Or, you could just use the Controller.Url property if you inherit from Controller.

public static function tzList()
{
    $tzMap = array();
    $zones = \DateTimeZone::listIdentifiers();
    foreach ($zones as $zone) {
        $tz = new \DateTimeZone($zone);
        $now = new \DateTime("utc", $tz);
        $diffInSeconds = $tz->getOffset($now);
        $hours = floor($diffInSeconds / 3600);
        $minutes = floor(($diffInSeconds % 3600) / 60);
        $tzMap[$zone] = sprintf("%+d", $hours) . ":" . sprintf("%02d", $minutes);
    }
    return $tzMap;
}

Tada! It's this simple. Gives you an array with the key as the PHP timezone and the value as a string in the format +-Hours:Minutes

For comparing 2 strings, either use the built in function strcmp() using header file string.h

if(strcmp(a,b)==0)
    printf("Entered strings are equal");
else
    printf("Entered strings are not equal");

OR you can write your own function like this:

int string_compare(char str1[], char str2[])
{
    int ctr=0;

    while(str1[ctr]==str2[ctr])
    {
        if(str1[ctr]=='\0'||str2[ctr]=='\0')
            break;
        ctr++;
    }
    if(str1[ctr]=='\0' && str2[ctr]=='\0')
        return 0;
    else
        return -1;
}

When you execute a script without typing "python" in front, you need to know two things about how Windows invokes the program. First is to find out what kind of file Windows thinks it is:

    C:\>assoc .py
    .py=Python.File

Next, you need to know how Windows is executing things with that extension. It's associated with the file type "Python.File", so this command shows what it will be doing:

    C:\>ftype Python.File
    Python.File="c:\python26\python.exe" "%1" %*

So on my machine, when I type "blah.py foo", it will execute this exact command, with no difference in results than if I had typed the full thing myself:

    "c:\python26\python.exe" "blah.py" foo

If you type the same thing, including the quotation marks, then you'll get results identical to when you just type "blah.py foo". Now you're in a position to figure out the rest of your problem for yourself.

(Or post more helpful information in your question, like actual cut-and-paste copies of what you see in the console. Note that people who do that type of thing get their questions voted up, and they get reputation points, and more people are likely to help them with good answers.)

Brought In From Comments:

Even if assoc and ftype display the correct information, it may happen that the arguments are stripped off. What may help in that case is directly fixing the relevant registry keys for Python. Set the

HKEY_CLASSES_ROOT\Applications\python26.exe\shell\open\command

key to:

"C:\Python26\python26.exe" "%1" %*

Likely, previously, %* was missing. Similarly, set

 HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

to the same value. See http://eli.thegreenplace.net/2010/12/14/problem-passing-arguments-to-python-scripts-on-windows/

HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command The registry path may vary, use python26.exe or python.exe or whichever is already in the registry.

HKEY_CLASSES_ROOT\py_auto_file\shell\open\command

The solution for me on a CentOS 8 system was checking the System Cryptography Policy by verifying the /etc/crypto-policies/config reads the default value of DEFAULT rather than any other value.

Once changing this value to DEFAULT, run the following command:

/usr/bin/update-crypto-policies --set DEFAULT

Rerun the curl command and it should work.

It is been a while since this question was asked but I had the same challenge and want to share my solution. It uses elements from the other answers but I wasn't able to find it in its entirety. It doesn't use a form or an iframe but it does require a post/get request pair. Instead of saving the file between the requests, it saves the post data. It seems to be both simple and effective.

client

var apples = new Array(); 
// construct data - replace with your own
$.ajax({
   type: "POST",
   url: '/Home/Download',
   data: JSON.stringify(apples),
   contentType: "application/json",
   dataType: "text",

   success: function (data) {
      var url = '/Home/Download?id=' + data;
      window.location = url;
   });
});

server

[HttpPost]
// called first
public ActionResult Download(Apple[] apples)
{
   string json = new JavaScriptSerializer().Serialize(apples);
   string id = Guid.NewGuid().ToString();
   string path = Server.MapPath(string.Format("~/temp/{0}.json", id));
   System.IO.File.WriteAllText(path, json);

   return Content(id);
}

// called next
public ActionResult Download(string id)
{
   string path = Server.MapPath(string.Format("~/temp/{0}.json", id));
   string json = System.IO.File.ReadAllText(path);
   System.IO.File.Delete(path);
   Apple[] apples = new JavaScriptSerializer().Deserialize<Apple[]>(json);

   // work with apples to build your file in memory
   byte[] file = createPdf(apples); 

   Response.AddHeader("Content-Disposition", "attachment; filename=juicy.pdf");
   return File(file, "application/pdf");
}

Console.WriteLine(curr.ToString("HH:mm"));

You can do something like this:

function writeFile(i){
    var i = i || 0;
    var fileName = 'a_' + i + '.jpg';
    fs.exists(fileName, function (exists) {
        if(exists){
            writeFile(++i);
        } else {
            fs.writeFile(fileName);
        }
    });
}

From my point of view the CLI you are using and the libraries are mismatched. The ionic CLI version 1 cannot build libraries for ionic CLI version 4. The best solution is to try upgrade your CLI version. You can otherwise use nvm which allows you to run multiple node versions on the same O.S. This can help you use different ionic CLI versions across different projects depending on the requirements.

Check out nvm @: Their official windows repo. There is also a MAC and Linux version.

var encoded = window.btoa(svg);
document.body.style.background = "url(data:image/svg+xml;base64,"+encoded+")";

Fiddle here!

1. First should understand the error meaning

Error not enough values to unpack (expected 3, got 2) means:

a 2 part tuple, but assign to 3 values

and I have written demo code to show for you:

#!/usr/bin/python
# -*- coding: utf-8 -*-
# Function: Showing how to understand ValueError 'not enough values to unpack (expected 3, got 2)'
# Author: Crifan Li
# Update: 20191212

def notEnoughUnpack():
    """Showing how to understand python error `not enough values to unpack (expected 3, got 2)`"""
    # a dict, which single key's value is two part tuple
    valueIsTwoPartTupleDict = {
        "name1": ("lastname1", "email1"),
        "name2": ("lastname2", "email2"),
    }

    # Test case 1: got value from key
    gotLastname, gotEmail = valueIsTwoPartTupleDict["name1"] # OK
    print("gotLastname=%s, gotEmail=%s" % (gotLastname, gotEmail))
    # gotLastname, gotEmail, gotOtherSomeValue = valueIsTwoPartTupleDict["name1"] # -> ValueError not enough values to unpack (expected 3, got 2)

    # Test case 2: got from dict.items()
    for eachKey, eachValues in valueIsTwoPartTupleDict.items():
        print("eachKey=%s, eachValues=%s" % (eachKey, eachValues))
    # same as following:
    # Background knowledge: each of dict.items() return (key, values)
    # here above eachValues is a tuple of two parts
    for eachKey, (eachValuePart1, eachValuePart2) in valueIsTwoPartTupleDict.items():
        print("eachKey=%s, eachValuePart1=%s, eachValuePart2=%s" % (eachKey, eachValuePart1, eachValuePart2))
    # but following:
    for eachKey, (eachValuePart1, eachValuePart2, eachValuePart3) in valueIsTwoPartTupleDict.items(): # will -> ValueError not enough values to unpack (expected 3, got 2)
        pass

if __name__ == "__main__":
    notEnoughUnpack()

using VSCode debug effect:

2. For your code

for name, email, lastname in unpaidMembers.items():

but error ValueError: not enough values to unpack (expected 3, got 2)

means each item(a tuple value) in unpaidMembers, only have 1 parts:email, which corresponding above code

    unpaidMembers[name] = email

so should change code to:

for name, email in unpaidMembers.items():

to avoid error.

But obviously you expect extra lastname, so should change your above code to

    unpaidMembers[name] = (email, lastname)

and better change to better syntax:

for name, (email, lastname) in unpaidMembers.items():

then everything is OK and clear.

I would like to add a design pattern that has been applied in Android Framework. This is Half Sync Half Async pattern used in the Asynctask implementation. See my discussion at

https://docs.google.com/document/d/1_zihWXAwgTAdJc013-bOLUHPMrjeUBZnDuPkzMxEEj0/edit?usp=sharing

IIF is a non-standard T-SQL function. It was added to SQL SERVER 2012, so that Access could migrate to SQL Server without refactoring the IIF's to CASE before hand. Once the Access db is fully migrated into SQL Server, you can refactor.

1. If you are using other managed objects that are using unmanaged resources, it is not your responsibility to ensure those are finalized. Your responsibility is to call Dispose on those objects when Dispose is called on your object, and it stops there.

2. If your class doesn't use any scarce resources, I fail to see why you would make your class implement IDisposable. You should only do so if you're:

   • Know you will have scarce resources in your objects soon, just not now (and I mean that as in "we're still developing, it will be here before we're done", not as in "I think we'll need this")
   • Using scarce resources

3. Yes, the code that uses your code must call the Dispose method of your object. And yes, the code that uses your object can use using as you've shown.

4. (2 again?) It is likely that the WebClient uses either unmanaged resources, or other managed resources that implement IDisposable. The exact reason, however, is not important. What is important is that it implements IDisposable, and so it falls on you to act upon that knowledge by disposing of the object when you're done with it, even if it turns out WebClient uses no other resources at all.

Source: My Blog Post (better formatting)

Example

numbers = [1,2,3]
letters = 'abcd'

zip(numbers, letters)
# [(1, 'a'), (2, 'b'), (3, 'c')]

Input

Zero or more iterables [1] (ex. list, string, tuple, dictionary)

Output (list)

1st tuple = (element_1 of numbers, element_1 of letters)

2nd tuple = (e_2 numbers, e_2 letters)

…

n-th tuple = (e_n numbers, e_n letters)

1. List of n tuples: n is the length of the shortest argument (input)
   • len(numbers) == 3 < len(letters) == 4 ? short= 3 ? return 3 tuples
2. Length each tuple = # of args (tuple takes an element from each arg)
   • args = (numbers,letters); len(args) == 2 ? tuple with 2 elements
3. ith tuple = (element_i arg1, element_i arg2…, element_i argn)

Edge Cases

1) Empty String: len(str)= 0 = no tuples

2) Single String: len(str) == 2 tuples with len(args) == 1 element(s)

zip()
# []
zip('')
# []
zip('hi')
# [('h',), ('i',)]

Zip in Action!

1. Build a dictionary [2] out of two lists

keys = ["drink","band","food"]
values = ["La Croix", "Daft Punk", "Sushi"]

my_favorite = dict( zip(keys, values) )

my_favorite["drink"]
# 'La Croix'

my_faves = dict()
for i in range(len(keys)):
    my_faves[keys[i]] = values[i]

• zip is an elegant, clear, & concise solution

2. Print columns in a table

"*" [3] is called "unpacking": f(*[arg1,arg2,arg3]) == f(arg1, arg2, arg3)

student_grades = [
[   'Morty'  ,  1   ,  "B"  ],
[   'Rick'   ,  4   ,  "A"  ],
[   'Jerry'  ,  3   ,  "M"  ],
[  'Kramer'  ,  0   ,  "F"  ],
]

row_1 = student_grades[0]
print row_1
# ['Morty', 1, 'B']

columns = zip(*student_grades)
names = columns[0]
print names
# ('Morty', 'Rick', 'Jerry', 'Kramer')

Extra Credit: Unzipping

zip(*args) is called “unzipping” because it has the inverse effect of zip

numbers = (1,2,3)
letters = ('a','b','c')

zipped = zip(numbers, letters)
print zipped
# [(1, 'a'), (2, 'b'), (3, 'c')]

unzipped = zip(*zipped)
print unzipped
# [(1, 2, 3), ('a', 'b', 'c')]

• unzipped: tuple_1 = e1 of each zipped tuple. tuple_2 = e2 of each zipped

Footnotes

1. An object capable of returning its members one at a time (ex. list [1,2,3], string 'I like codin', tuple (1,2,3), dictionary {'a':1, 'b':2})
2. {key1:value1, key2:value2...}
3. “Unpacking” (*)

* Code:

# foo - function, returns sum of two arguments
def foo(x,y):
    return x + y
print foo(3,4)
# 7

numbers = [1,2]
print foo(numbers)
# TypeError: foo() takes exactly 2 arguments (1 given)

print foo(*numbers)
# 3

* took numbers (1 arg) and “unpacked” its’ 2 elements into 2 args

I have use below code to encode the special character by specifying encode format.

String text = "This is an example é";
byte[] byteText = text.getBytes(Charset.forName("UTF-8"));
//To get original string from byte.
String originalString= new String(byteText , "UTF-8");

try this

sp1 = String.valueOf(spinner.getSelectedItem());

One of my favourite :)

Expanding on the method pointed to at docs.djangoproject.com:

class MyForm(forms.Form): 
    comment = forms.CharField(
            widget=forms.TextInput(attrs={'size':'40'}))

I thought it was troublesome to have to know the native widget type for every field, and thought it funny to override the default just to put a class name on a form field. This seems to work for me:

class MyForm(forms.Form): 
    #This instantiates the field w/ the default widget
    comment = forms.CharField()

    #We only override the part we care about
    comment.widget.attrs['size'] = '40'

This seems a little cleaner to me.

Node.js does not run in a browser, therefore you will not have a document object available. Actually, you will not even have a DOM tree at all. If you are a bit confused at this point, I encourage you to read more about it before going further.

There are a few methods you can choose from to do what you want.

Method 1: Serving the file directly via HTTP

Because you wrote about opening the file in the browser, why don't you use a framework that will serve the file directly as an HTTP service, instead of having a two-step process? This way, your code will be more dynamic and easily maintainable (not mentioning your HTML always up-to-date).

There are plenty frameworks out there for that :

• Http (Node native API)
• Connect
• koa
• Express (using Connect)
• Sails (build on Express)
• Geddy
• CompoundJS
• etc.

The most basic way you could do what you want is this :

var http = require('http');

http.createServer(function (req, res) {
  var html = buildHtml(req);

  res.writeHead(200, {
    'Content-Type': 'text/html',
    'Content-Length': html.length,
    'Expires': new Date().toUTCString()
  });
  res.end(html);
}).listen(8080);

function buildHtml(req) {
  var header = '';
  var body = '';

  // concatenate header string
  // concatenate body string

  return '<!DOCTYPE html>'
       + '<html><head>' + header + '</head><body>' + body + '</body></html>';
};

And access this HTML with http://localhost:8080 from your browser.

(Edit: you could also serve them with a small HTTP server.)

Method 2: Generating the file only

If what you are trying to do is simply generating some HTML files, then go simple. To perform IO access on the file system, Node has an API for that, documented here.

var fs = require('fs');

var fileName = 'path/to/file';
var stream = fs.createWriteStream(fileName);

stream.once('open', function(fd) {
  var html = buildHtml();

  stream.end(html);
});

Note: The buildHtml function is exactly the same as in Method 1.

Method 3: Dumping the file directly into stdout

This is the most basic Node.js implementation and requires the invoking application to handle the output itself. To output something in Node (ie. to stdout), the best way is to use console.log(message) where message is any string, or object, etc.

var html = buildHtml();

console.log(html);

Note: The buildHtml function is exactly the same as in Method 1 (again)

If your script is called html-generator.js (for example), in Linux/Unix based system, simply do

$ node html-generator.js > path/to/file

Conclusion

Because Node is a modular system, you can even put the buildHtml function inside it's own module and simply write adapters to handle the HTML however you like. Something like

var htmlBuilder = require('path/to/html-builder-module');

var html = htmlBuilder(options);
...

You have to think "server-side" and not "client-side" when writing JavaScript for Node.js; you are not in a browser and/or limited to a sandbox, other than the V8 engine.

Extra reading, learn about npm. Hope this helps.

Getting SOAP working usually does not require compiling PHP from source. I would recommend trying that only as a last option.

For good measure, check to see what your phpinfo says, if anything, about SOAP extensions:

$ php -i | grep -i soap

to ensure that it is the PHP extension that is missing.

Assuming you do not see anything about SOAP in the phpinfo, see what PHP SOAP packages might be available to you.

In Ubuntu/Debian you can search with:

$ apt-cache search php | grep -i soap

or in RHEL/Fedora you can search with:

$ yum search php | grep -i soap

There are usually two PHP SOAP packages available to you, usually php-soap and php-nusoap. php-soap is typically what you get with configuring PHP with --enable-soap.

In Ubuntu/Debian you can install with:

$ sudo apt-get install php-soap

Or in RHEL/Fedora you can install with:

$ sudo yum install php-soap

After the installation, you might need to place an ini file and restart Apache.

This flexbox principle also works horizontally

During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Setting an automatic left margin for the Last Item will do the work.

.last-item {
  margin-left: auto;
}

Code Example:

.container {_x000D_
  display: flex;_x000D_
  width: 400px;_x000D_
  outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  margin: 5px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
  margin-left: auto;_x000D_
}

<div class="container">_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p class="last-item"></p>_x000D_
</div>

I have resolved the problem by adding below code to manifest,

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/ic_stat_name" />

    <meta-data
        android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/black" />

where ic_stat_name created on Android Studio Right Click on res >> New >>Image Assets >> IconType(Notification)

And one more step I have to do on server php side with notification payload

$message = [
    "message" => [
        "notification" => [
            "body"  => $title , 
            "title" => $message
        ],

        "token" => $token,

    "android" => [
           "notification" => [
            "sound"  => "default",
            "icon"  => "ic_stat_name"
            ]
        ],

       "data" => [
            "title" => $title,
            "message" => $message
         ]


    ]
];

Note the section

    "android" => [
           "notification" => [
            "sound"  => "default",
            "icon"  => "ic_stat_name"
            ]
        ]

where icon name is "icon" => "ic_stat_name" should be the same set on manifest.

   function callServlet()


{
 document.getElementById("adminForm").action="./Administrator";
 document.getElementById("adminForm").method = "GET";
 document.getElementById("adminForm").submit();

}

<button type="submit"  onclick="callServlet()" align="center"> Register</button>

You could create a mutable wrapper of the primitive int and create a Set of those:

class MutableInteger
{
    private int value;
    public int getValue()
    {
        return value;
    }
    public void setValue(int value)
    {
        this.value = value;
    }
}

class Test
{
    public static void main(String[] args)
    {
        Set<MutableInteger> mySet = new HashSet<MutableInteger>();
        // populate the set
        // ....

        for (MutableInteger integer: mySet)
        {
            integer.setValue(integer.getValue() + 1);
        }
    }
}

Of course if you are using a HashSet you should implement the hash, equals method in your MutableInteger but that's outside the scope of this answer.

My fix for this was my child table needed to be populated before the parent table.

I had two tables: UserDetails and Login linked by an email address. I therefore had to insert into the UserDetails first before inserting into the Login table:

insert into UserDetails (Email, Name, Telephone, Department) values ('Email', 'Name', 'number', 'IT');

Then:

insert into Login (UserID, UserType, Email, Username, Password) VALUES (001, 'SYS-USR-ADMIN', 'Email', 'Name', 'Password')

But I realize a trouble that TextView will be truncated by word (in default). Show if we have a text like:

test long_line_without_any_space_abcdefgh

the TextView will display:

test...

And I found solution to handle this trouble, replace spaces with the unicode no-break space character, it makes TextView wrap on characters instead of words:

yourString.replace(" ", "\u00A0");

The result:

test long_line_without_any_space_abc...

Cache Busting in ASP.NET Core via a tag helper will handle this for you and allow your browser to keep cached scripts/css until the file changes. Simply add the tag helper asp-append-version="true" to your script (js) or link (css) tag:

<link rel="stylesheet" href="~/css/site.min.css" asp-append-version="true"/>

Dave Paquette has a good example and explanation of cache busting here (bottom of page) Cache Busting

Haskell's standard list data type forall t. [t] in implementation closely resembles a canonical C linked list, and shares its essentially properties. Linked lists are very different from arrays. Most notably, access by index is a O(n) linear-, instead of a O(1) constant-time operation.

If you require frequent random access, consider the Data.Array standard.

!! is an unsafe partially defined function, provoking a crash for out-of-range indices. Be aware that the standard library contains some such partial functions (head, last, etc.). For safety, use an option type Maybe, or the Safe module.

Example of a reasonably efficient, robust total (for indices = 0) indexing function:

data Maybe a = Nothing | Just a

lookup :: Int -> [a] -> Maybe a
lookup _ []       = Nothing
lookup 0 (x : _)  = Just x
lookup i (_ : xs) = lookup (i - 1) xs

Working with linked lists, often ordinals are convenient:

nth :: Int -> [a] -> Maybe a
nth _ []       = Nothing
nth 1 (x : _)  = Just x
nth n (_ : xs) = nth (n - 1) xs

Extended Chris Pickett's answer because in my case I needed to search deeper than one attribute level:

function findWithAttr(array, attr, value) {
  if (attr.indexOf('.') >= 0) {
    var split = attr.split('.');
    var attr1 = split[0];
    var attr2 = split[1];
    for(var i = 0; i < array.length; i += 1) {
      if(array[i][attr1][attr2] === value) {
        return i;
      }
    }
  } else {
    for(var i = 0; i < array.length; i += 1) {
      if(array[i][attr] === value) {
        return i;
      }
    }
  };
};

You can pass 'attr1.attr2' into the function

A modification to @ivanperelivskiy's answer:

@property
def _dict(self):
    ret = {}
    for field in self._meta.get_fields():
        if isinstance(field, ForeignObjectRel):
            # foreign objects might not have corresponding objects in the database.
            if hasattr(self, field.get_accessor_name()):
                ret[field.get_accessor_name()] = getattr(self, field.get_accessor_name())
            else:
                ret[field.get_accessor_name()] = None
        else:
            ret[field.attname] = getattr(self, field.attname)
    return ret

This uses django 1.10's public method get_fields instead. This makes the code more future proof, but more importantly also includes foreign keys and fields where editable=False.

For reference, here is the implementation of .fields

@cached_property
def fields(self):
    """
    Returns a list of all forward fields on the model and its parents,
    excluding ManyToManyFields.

    obtaining this field list.
    """
    # For legacy reasons, the fields property should only contain forward
    # fields that are not private or with a m2m cardinality. Therefore we
    # pass these three filters as filters to the generator.
    # The third lambda is a longwinded way of checking f.related_model - we don't
    # use that property directly because related_model is a cached property,
    # and all the models may not have been loaded yet; we don't want to cache
    # the string reference to the related_model.
    def is_not_an_m2m_field(f):
        return not (f.is_relation and f.many_to_many)

    def is_not_a_generic_relation(f):

            f.is_relation and f.many_to_one and not (hasattr(f.remote_field, 'model') and f.remote_field.model)
        )

    return make_immutable_fields_list(
        "fields",
        (f for f in self._get_fields(reverse=False)

Why don't you use the MySQL built in password hasher:

http://dev.mysql.com/doc/refman/5.1/en/password-hashing.html

mysql> SELECT PASSWORD('mypass');
+-------------------------------------------+
| PASSWORD('mypass')                        |
+-------------------------------------------+
| *6C8989366EAF75BB670AD8EA7A7FC1176A95CEF4 |
+-------------------------------------------+

for comparison you could something like this:

select id from PassworTable where Userid='<userid>' and Password=PASSWORD('<password>')

and if it returns a value then the user is correct.

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

import csv
inf = csv.reader(open('yourfile.csv','r'))

The vertical-align attribute is for inline elements only. It will have no effect on block level elements, like a div. Also text-top only moves the text to the top of the current font size. If you would like to vertically align an inline element to the top just use this.

vertical-align: top;

The paragraph tag is not outdated. Also, the vertical-align attribute applied to a span element may not display as intended in some mozilla browsers.

Assuming you wanted to do this synchronously, using the WebClient.OpenRead(...) method and setting the timeout on the Stream that it returns will give you the desired result:

using (var webClient = new WebClient())
using (var stream = webClient.OpenRead(streamingUri))
{
     if (stream != null)
     {
          stream.ReadTimeout = Timeout.Infinite;
          using (var reader = new StreamReader(stream, Encoding.UTF8, false))
          {
               string line;
               while ((line = reader.ReadLine()) != null)
               {
                    if (line != String.Empty)
                    {
                        Console.WriteLine("Count {0}", count++);
                    }
                    Console.WriteLine(line);
               }
          }
     }
}

Deriving from WebClient and overriding GetWebRequest(...) to set the timeout @Beniamin suggested, didn't work for me as, but this did.

You should only have one <system.web> in your Web.Config Configuration File.

<?xml version="1.0"?>

    <authentication mode="None"/>

I test examples in js. Simplest solution - just add word u need inside / /:

var reg = /cat/;
reg.test('some cat here');//1 test
true // result
reg.test('acatb');//2 test
true // result

Now if u need this specific word with boundaries, not inside any other signs-letters. We use b marker:

var reg = /\bcat\b/
reg.test('acatb');//1 test 
false // result
reg.test('have cat here');//2 test
true // result

We have also exec() method in js, whichone returns object-result. It helps f.g. to get info about place/index of our word.

var matchResult = /\bcat\b/.exec("good cat good");
console.log(matchResult.index); // 5

If we need get all matched words in string/sentence/text, we can use g modifier (global match):

"cat good cat good cat".match(/\bcat\b/g).length
// 3 

Now the last one - i need not 1 specific word, but some of them. We use | sign, it means choice/or.

"bad dog bad".match(/\bcat|dog\b/g).length
// 1

There is a better way which don't need you to alter the table:

mysql> DROP INDEX email ON fuinfo;

where email is the name of unique key (index).

You can also bring it back like that:

mysql> CREATE UNIQUE INDEX email ON fuinfo(email);

where email after IDEX is the name of the index and it's not optional. You can use KEY instead of INDEX.

Also it's possible to create (remove) multicolumn unique indecies like that:

mysql> CREATE UNIQUE INDEX email_fid ON fuinfo(email, fid);
mysql> DROP INDEX email_fid ON fuinfo;

If you didn't specify the name of multicolumn index you can remove it like that:

mysql> DROP INDEX email ON fuinfo;

where email is the column name.

Try this:

body {
  background-image:url(img/background.jpg);
  background-repeat: no-repeat;
  min-height: 679px;
  background-size: cover;
}

Fix Step by step:

If you not have vbguest plugin, install it:

$ vagrant plugin install vagrant-vbguest

Run Vagrant

It is show a error.

$ vagrant up

Login on VM

$ vagrant ssh

Fix!

In the guest (VM logged).

$ sudo ln -s /opt/VBoxGuestAdditions-4.3.10/lib/VBoxGuestAdditions /usr/lib/VBoxGuestAdditions

Back on the host, reload Vagrant

$ vagrant reload

\d is a digit (a character in the range 0-9), and + means 1 or more times. So, \d+ is 1 or more digits.

This is about as simple as regular expressions get. You should try reading up on regular expressions a little bit more. Google has a lot of results for regular expression tutorial, for instance. Or you could try using a tool like the free Regex Coach that will let you enter a regular expression and sample text, then indicate what (if anything) matches the regex.

I'm in windows 10, using WAMP64 server. Searched for my.cnf and my.ini. Found my.ini in C:\wamp64\bin\mariadb\mariadb10.2.14.

Following the instructions from the colleagues:

1. Opened the quick start menu from Wampserver, selected 'Stop All Services'
2. Opened my.ini in a text editor, searched for [mysqld]
3. Added 'skip-grant-tables' at the end of the [mysqld] section (but within it)
4. Save the file, leave the editor open
5. In the Wampserver menu, select "Restart Services'. There will be a warning about the skip-grant-tables option
6. In the Wampserver menu select MySQL to open the prompt
7. It asked for a password, just press enter
8. Paste the command ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'newpassword';
9. It must report that the operation was successful (no tables affected)
10. In the my.ini file, erase the 'skip-grant-tables' line, save the file
11. In the WampServer menu, select once more Restart Service

Now you can enter with the new password. Thanks to all answers here.

Below code worked for me:

<input #fileInput type="file" id="avatar" accept="application/pdf,application/msword,application/vnd.openxmlformats-officedocument.wordprocessingml.document" />

application/pdf means .pdf
application/msword means .doc
application/vnd.openxmlformats-officedocument.wordprocessingml.document means .docx

You have to be careful about the xib file. I tried all the above and nothing worked for me. I was using custom UIButtons defined in the xib, and realized it might be related to the fact that I had assigned attributes there which were not changing programmatically. If you've defined images or text there, remove them. When I did, my programmatic changes began to take effect.

First connect the Height constraint in to our viewcontroller for creating IBOutlet like the below code shown

@IBOutlet weak var select_dateHeight: NSLayoutConstraint!

then put the below code in view did load or inside any actions

self.select_dateHeight.constant = 0 // we can change the height value

if it is inside a button click

@IBAction func Feedback_button(_ sender: Any) {
 self.select_dateHeight.constant = 0

}

See if the below helps you:

I was using the following earlier:

ClientScript.RegisterClientScriptBlock(Page.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>");

After implementing AJAX in this page, it stopped working. After reading your blog, I changed the above to:

ScriptManager.RegisterClientScriptBlock(imgBtnSubmit, this.GetType(), "AlertMsg", "<script language='javascript'>alert('The Web Policy need to be accepted to submit the new assessor information.');</script>", false);

This is working perfectly fine.

(It’s .NET 2.0 Framework, I am using)

For those who don't have ImageMagick for whatever reason, GD functions will also work, in conjunction with GhostScript. Run the ghostscript command with exec() to convert a PDF to JPG, and manipulate the resulting file with imagecreatefromjpeg().

Run the ghostscript command:

exec('gs -dSAFER -dBATCH -sDEVICE=jpeg -dTextAlphaBits=4 -dGraphicsAlphaBits=4 -r300 -sOutputFile=whatever.jpg input.pdf')

To manipulate, create a new placeholder image, $newimage = imagecreatetruecolor(...), and bring in the current image. $image = imagecreatefromjpeg('whatever.jpg'), and then you can use imagecopyresampled() to change the size, or any number of other built-in, non-imagemagick commands

To convert the byte[] to string[], simply use the below line.

byte[] fileData; // Some byte array
//Convert byte[] to string[]
var table = (Encoding.Default.GetString(
                 fileData, 
                 0, 
                 fileData.Length - 1)).Split(new string[] { "\r\n", "\r", "\n" },
                                             StringSplitOptions.None);

See this article for a longer discussion of named actions. It also shows that you can use the [HttpGet] attribute instead of prefixing the action name with "get".

I solved this question this way.

<a class="btn btn-primary" target="_blank" ng-href="{{url}}" ng-mousedown="openTab()">newTab</a>

$scope.openTab = function() {
    $scope.url = 'www.google.com';
}

You can use the dictionary type of formatting:

s='arbit'
string='%(key)s hello world %(key)s hello world %(key)s' % {'key': s,}

You can just use the -R (recursive) flag.

chmod -R 777 /Users/Test/Desktop/PATH

The critical step is getting the merge itself to be in-place. It's not as difficult as those sources make out, but you lose something when you try.

Looking at one step of the merge:

[...list-sorted...|x...list-A...|y...list-B...]

We know that the sorted sequence is less than everything else, that x is less than everything else in A, and that y is less than everything else in B. In the case where x is less than or equal to y, you just move your pointer to the start of A on one. In the case where y is less than x, you've got to shuffle y past the whole of A to sorted. That last step is what makes this expensive (except in degenerate cases).

It's generally cheaper (especially when the arrays only actually contain single words per element, e.g., a pointer to a string or structure) to trade off some space for time and have a separate temporary array that you sort back and forth between.

Running in Windows Services any application like for example ".exe" is weird to do because the algorithm is not that effective.

I understand that Node.js uses a single-thread and an event loop to process requests only processing one at a time (which is non-blocking).

I could be misunderstanding what you've said here, but "one at a time" sounds like you may not be fully understanding the event-based architecture.

In a "conventional" (non event-driven) application architecture, the process spends a lot of time sitting around waiting for something to happen. In an event-based architecture such as Node.js the process doesn't just wait, it can get on with other work.

For example: you get a connection from a client, you accept it, you read the request headers (in the case of http), then you start to act on the request. You might read the request body, you will generally end up sending some data back to the client (this is a deliberate simplification of the procedure, just to demonstrate the point).

At each of these stages, most of the time is spent waiting for some data to arrive from the other end - the actual time spent processing in the main JS thread is usually fairly minimal.

When the state of an I/O object (such as a network connection) changes such that it needs processing (e.g. data is received on a socket, a socket becomes writable, etc) the main Node.js JS thread is woken with a list of items needing to be processed.

It finds the relevant data structure and emits some event on that structure which causes callbacks to be run, which process the incoming data, or write more data to a socket, etc. Once all of the I/O objects in need of processing have been processed, the main Node.js JS thread will wait again until it's told that more data is available (or some other operation has completed or timed out).

The next time that it is woken, it could well be due to a different I/O object needing to be processed - for example a different network connection. Each time, the relevant callbacks are run and then it goes back to sleep waiting for something else to happen.

The important point is that the processing of different requests is interleaved, it doesn't process one request from start to end and then move onto the next.

To my mind, the main advantage of this is that a slow request (e.g. you're trying to send 1MB of response data to a mobile phone device over a 2G data connection, or you're doing a really slow database query) won't block faster ones.

In a conventional multi-threaded web server, you will typically have a thread for each request being handled, and it will process ONLY that request until it's finished. What happens if you have a lot of slow requests? You end up with a lot of your threads hanging around processing these requests, and other requests (which might be very simple requests that could be handled very quickly) get queued behind them.

There are plenty of others event-based systems apart from Node.js, and they tend to have similar advantages and disadvantages compared with the conventional model.

I wouldn't claim that event-based systems are faster in every situation or with every workload - they tend to work well for I/O-bound workloads, not so well for CPU-bound ones.

You need to use : "$@" (WITH the quotes) or "${@}" (same, but also telling the shell where the variable name starts and ends).

(and do NOT use : $@, or "$*", or $*).

ex:

#testscript1:
echo "TestScript1 Arguments:"
for an_arg in "$@" ; do
   echo "${an_arg}"
done
echo "nb of args: $#"
./testscript2 "$@"   #invokes testscript2 with the same arguments we received

I'm not sure I understood your other requirement ( you want to invoke './testscript2' in single quotes?) so here are 2 wild guesses (changing the last line above) :

'./testscript2' "$@"  #only makes sense if "/path/to/testscript2" containes spaces?

./testscript2 '"some thing" "another"' "$var" "$var2"  #3 args to testscript2

Please give me the exact thing you are trying to do

edit: after his comment saying he attempts tesscript1 "$1" "$2" "$3" "$4" "$5" "$6" to run : salt 'remote host' cmd.run './testscript2 $1 $2 $3 $4 $5 $6'

You have many levels of intermediate: testscript1 on host 1, needs to run "salt", and give it a string launching "testscrit2" with arguments in quotes...

You could maybe "simplify" by having:

#testscript1

#we receive args, we generate a custom script simulating 'testscript2 "$@"'
theargs="'$1'"
shift
for i in "$@" ; do
   theargs="${theargs} '$i'"
done

salt 'remote host' cmd.run "./testscript2 ${theargs}"

if THAt doesn't work, then instead of running "testscript2 ${theargs}", replace THE LAST LINE above by

echo "./testscript2 ${theargs}" >/tmp/runtestscript2.$$  #generate custom script locally ($$ is current pid in bash/sh/...)
scp /tmp/runtestscript2.$$ user@remotehost:/tmp/runtestscript2.$$ #copy it to remotehost
salt 'remotehost' cmd.run "./runtestscript2.$$" #the args are inside the custom script!
ssh user@remotehost "rm /tmp/runtestscript2.$$" #delete the remote one
rm /tmp/runtestscript2.$$ #and the local one

You can use this method to draw polyline on googleMap

// Draw polyline on map
public void drawPolyLineOnMap(List<LatLng> list) {
    PolylineOptions polyOptions = new PolylineOptions();
    polyOptions.color(Color.RED);
    polyOptions.width(5);
    polyOptions.addAll(list);

    googleMap.clear();
    googleMap.addPolyline(polyOptions);

    LatLngBounds.Builder builder = new LatLngBounds.Builder();
    for (LatLng latLng : list) {
        builder.include(latLng);
    }

    final LatLngBounds bounds = builder.build();

    //BOUND_PADDING is an int to specify padding of bound.. try 100.
    CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, BOUND_PADDING);
    googleMap.animateCamera(cu);
}

You need to add this line in your gradle in case you haven't.

You can simply call filter multiple times:

query = meta.Session.query(User).filter(User.firstname.like(searchVar1)). \
                                 filter(User.lastname.like(searchVar2))

As I can see, you are comparing the message with the empty string using ==.

Its very hard to write the full code, but I can tell the flow of code - first, create db class & method inide that which will return the connection. second, create a servelet(ex-login.java) & import that db class onto that servlet. third, create instance of imported db class with the help of new operator & call the connection method of that db class. fourth, creaet prepared statement & execute statement & put this code in try catch block for exception handling.Use if-else condition in the try block to navigate your login page based on success or failure.

You will need to use the IO.Directory.GetFiles function.

Dim files() As String = IO.Directory.GetFiles("c:\")

For Each file As String In files
  ' Do work, example
  Dim text As String = IO.File.ReadAllText(file)
Next

1. open cmd

   • type in netstat -a -n -o

   • find TCP [the IP address]:[port number] .... #[target_PID]# (ditto for UDP)

   • (Btw, kill [target_PID] didn't work for me)

2. CTRL+ALT+DELETE and choose "start task manager"

   • Click on "Processes" tab

   • Enable "PID" column by going to: View > Select Columns > Check the box for PID

   • Find the PID of interest and "END PROCESS"

3. Now you can rerun the server on [the IP address]:[port number] without a problem

As for the meaning of each character described in C Primer Plus, what you expected is an 'correct' answer. It should be true for some computer architectures and compilers, but unfortunately not yours.

I wrote a simple c program to repeat your test, and got that 'correct' answer. I was using Mac OS and gcc.

Also, I am very curious what is the compiler that you were using. :)

Here is couple of ways to calculate length of variable :

echo ${#VAR}
echo -n $VAR | wc -m
echo -n $VAR | wc -c
printf $VAR | wc -m
expr length $VAR
expr $VAR : '.*'

and to set the result in another variable just assign above command with back quote into another variable as following:

otherVar=`echo -n $VAR | wc -m`   
echo $otherVar

I would like to improve the code. When you canel the aSyncTask the onCancelled() (callback method of aSyncTask) gets automatically called, and there you can hide your progressBarDialog.

You can include this code as well:

public class information extends AsyncTask<String, String, String>
    {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
        }

        @Override
        protected String doInBackground(String... arg0) {
            return null;
        }

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            this.cancel(true);
        }

        @Override
        protected void onProgressUpdate(String... values) {
            super.onProgressUpdate(values);
        }

        @Override
        protected void onCancelled() {
            Toast.makeText(getApplicationContext(), "asynctack cancelled.....", Toast.LENGTH_SHORT).show();
            dialog.hide(); /*hide the progressbar dialog here...*/
            super.onCancelled();
        }

    }

I’ve got a similar problem with MySQL on a Mac (Mac Os X Could not startup MySQL Server. Reason: 255 and also “ERROR! The server quit without updating PID file”). After a long trial and error process, finally in order to restore the file permissions, I’ve just do that:

* launch the Disk Utilities.app
* choose my drive on the left panel
* click on the “Repair disk permissions” button

This did the trick for me.

Hoping this can help someone else.

Objects and instances are mostly same; but there is a very small difference. If Car is a class, 3 Cars are 3 different objects. All of these objects are instances. So these 3 cars are objects from instances of the Car class.

But the word "instance" can mean "structure instance" also. But object is only for classes.

All of the objects are instances. Not all of the instances must be objects. Instances may be "structure instances" or "objects". I hope this makes the difference clear to you.

You could just re-direct specific numbers in your contacts to your voice-mail. That's already supported.

Otherwise I guess the documentation for 'Contacts' would be a good place to start looking.

While I agree with the most voted answer, here is another way to keep all rows except the first:

dat <- tail(dat, -1)

This can also be accomplished using Hadley Wickham's dplyr package.

dat <- dat %>% slice(-1)

Another implementation, while recursive is very fast and uses single inline function. It hits the javascript 64-bit number precision limit, starting 80th sequence (as do all other algorithms): For example if you want the 78th term (78 goes in the last parenthesis):

(function (n,i,p,r){p=(p||0)+r||1;i=i?i+1:1;return i<=n?arguments.callee(n,i,r,p):r}(78));

will return: 8944394323791464

This is backwards compatible all the way to ECMASCRIPT4 - I tested it with IE7 and it works!

If you want to display the JSON data in well defined formate you can modify the code as:

file_put_contents($file, json_encode($json,TRUE));


$headers = array('http'=>array('method'=>'GET','header'=>'Content: type=application/json \r\n'.'$agent \r\n'.'$hash'));

$context=stream_context_create($headers);

$str = file_get_contents("list.txt",FILE_USE_INCLUDE_PATH,$context);

$str1=utf8_encode($str);

$str1=json_decode($str1,true);



foreach($str1 as $key=>$value)
{

    echo "key is: $key.\n";

    echo "values are: \t";
        foreach ($value as $k) {

        echo " $k. \t";
        # code...
    }
        echo "<br></br>";
        echo "\n";

}

1st Approach (via Request or FormCollection):

You can read it from Request using Request.Form , your dropdown name is ddlVendor so pass ddlVendor key in the formCollection to get its value that is posted by form:

string strDDLValue = Request.Form["ddlVendor"].ToString();

or Use FormCollection:

[HttpPost]
public ActionResult ShowAllMobileDetails(MobileViewModel MV,FormCollection form)
{           
  string strDDLValue = form["ddlVendor"].ToString();

  return View(MV);
}

2nd Approach (Via Model):

If you want with Model binding then add a property in Model:

public class MobileViewModel 
{          
    public List<tbInsertMobile> MobileList;
    public SelectList Vendor { get; set; }
    public string SelectedVendor {get;set;}
}

and in View:

@Html.DropDownListFor(m=>m.SelectedVendor , Model.Vendor, "Select Manufacurer")

and in Action:

[HttpPost]
public ActionResult ShowAllMobileDetails(MobileViewModel MV)
{           
   string SelectedValue = MV.SelectedVendor;
   return View(MV);
}

UPDATE:

If you want to post the text of selected item as well, you have to add a hidden field and on drop down selection change set selected item text in the hidden field:

public class MobileViewModel 
{          
    public List<tbInsertMobile> MobileList;
    public SelectList Vendor { get; set; }
    public string SelectVendor {get;set;}
    public string SelectedvendorText { get; set; }
}

use jquery to set hidden field:

<script type="text/javascript">
$(function(){
$("#SelectedVendor").on("change", function {
   $("#SelectedvendorText").val($(this).text());
 });
});
</script>

@Html.DropDownListFor(m=>m.SelectedVendor , Model.Vendor, "Select Manufacurer")
@Html.HiddenFor(m=>m.SelectedvendorText)

Use this way:

$selectOption = $_POST['taskOption'];

But it is always better to give values to your <option> tags.

<select name="taskOption">
  <option value="1">First</option>
  <option value="2">Second</option>
  <option value="3">Third</option>
</select>

I'm not sure if I understand your question properly, but it shouldn't matter if this div is a child of some other div. You can simply get text from all divs with class bgHeaderH2 by using following code:

$(".bgHeaderH2").text();

Here is NGINX solution

file

remove

If you render the same view when the form is not valid then in template you can access the form errors using form.errors.

{% if form.errors %}
    {% for field in form %}
        {% for error in field.errors %}
            <div class="alert alert-danger">
                <strong>{{ error|escape }}</strong>
            </div>
        {% endfor %}
    {% endfor %}
    {% for error in form.non_field_errors %}
        <div class="alert alert-danger">
            <strong>{{ error|escape }}</strong>
        </div>
    {% endfor %}
{% endif %}

An example:

def myView(request):
    form = myForm(request.POST or None, request.FILES or None)
    if request.method == 'POST':
        if form.is_valid():
            return HttpResponseRedirect('/thanks/')
    return render(request, 'my_template.html', {'form': form})

header( "refresh:5;url=wherever.php" );

indeed you can use this code as teneff said, but you don't have to necessarily put the header before any sent output (this would output a "cannot relocate header.... :3 error").

To solve this use the php function ob_start(); before any html is outputed.

To terminate the ob just put ob_end_flush(); after you don't have any html output.

cheers!

If you want to disable the clickable, you can also add inline this in html

style="cursor: not-allowed;"

For Size : fa-lg, fa-2x, fa-3x, fa-4x, fa-5x.

For Color : <i class="fa fa-link fa-lg" aria-hidden="true"style="color:indianred"></i>

For Shadow : .fa-linkedin-square{text-shadow: 3px 6px #272634;}

SELECT CONVERT(VARCHAR,@date,112) + 
LEFT(REPLACE(CONVERT(VARCHAR,@date,114),':',''),6)

This is a common problem. You're almost certainly running into permissions issues. To solve it, make sure that the apache user has read/write access to your entire repository. To do that, chown -R apache:apache *, chmod -R 664 * for everything under your svn repository.

Also, see here and here if you're still stuck.

Update to answer OP's additional question in comments:

The "664" string is an octal (base 8) representation of the permissions. There are three digits here, representing permissions for the owner, group, and everyone else (sometimes called "world"), respectively, for that file or directory.

Notice that each base 8 digit can be represented with 3 bits (000 for '0' through 111 for '7'). Each bit means something:

• first bit: read permissions
• second bit: write permissions
• third bit: execute permissions

For example, 764 on a file would mean that:

• the owner (first digit) has read/write/execute (7) permission
• the group (second digit) has read/write (6) permission
• everyone else (third digit) has read (4) permission

Hope that clears things up!

Solution for Kotlin (Android 3.3, Kotlin 1.3.20)

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    supportActionBar!!.elevation = 0f
}

I would use

like 'Express Edition%'

Example:

DECLARE @edition varchar(50); 
set @edition = cast((select SERVERPROPERTY ('edition')) as varchar)

DECLARE @isExpress bit
if @edition like 'Express Edition%'
    set @isExpress = 1;
else
    set @isExpress = 0;

print @isExpress

You also need to define PHPIniDir - c:/php_install_path

Since Bootstrap 3 you have to use checkbox-inline and radio-inline classes on the label.

This takes care of vertical alignment.

<label class="checkbox-inline">
    <input type="checkbox" id="inlineCheckbox1" value="option1"> 1
</label>
<label class="radio-inline">
    <input type="radio" name="inlineRadioOptions" id="inlineRadio1" value="option1"> 1
</label>

If you're using ngRoute, you can inject $routeParams into your controller

First you should check how many commits you have:

git log

There are two status:

One is that there are only two commits:

For example:

commit A
commit B

(In this case, you can't use git rebase to do) you need to do following.

$ git reset --soft HEAD^1

$ git commit --amend

Another is that there are more than two commits; you want to merge commit C and D.

For example:

commit A
commit B
commit C
commit D

(under this condition, you can use git rebase)

git rebase -i B

And than use "squash" to do. The rest thins is very easy. If you still don't know, please read http://zerodie.github.io/blog/2012/01/19/git-rebase-i/

Simply apply aggregation function, Sum on your column

df.groupby('steps').sum().show()

I like this solution best. Simple, scalable, responsive. The idea here is to create a zero-height outer div with bottom padding set to the aspect ratio of the video. The iframe is scaled to 100% in both width and height, completely filling the outer container. The outer container automatically adjusts its height according to its width, and the iframe inside adjusts itself accordingly.

<div style="position:relative; width:100%; height:0px; padding-bottom:56.25%;">
    <iframe style="position:absolute; left:0; top:0; width:100%; height:100%"
        src="http://www.youtube.com/embed/RksyMaJiD8Y">
    </iframe>
</div>

The only variable here is the padding-bottom value in the outer div. It's 75% for 4:3 aspect ratio videos, and 56.25% for widescreen 16:9 aspect ratio videos.

adding this worked for me:

<link href="https://fortawesome.github.io/Font-Awesome/assets/font-awesome/css/font-awesome.css" rel="stylesheet">

take a look

so full example is:

<link href="https://github.com/FortAwesome/Font-Awesome/blob/master/web-fonts-with-css/css/fontawesome.css" rel="stylesheet">_x000D_
<a class="btn-cta-freequote" href="#">Compute <i class="fa fa-calculator"></i></a>

It's the comma which is providing that extra white space.

One way is to use the string % method:

print 'Value is "%d"' % (value)

which is like printf in C, allowing you to incorporate and format the items after % by using format specifiers in the string itself. Another example, showing the use of multiple values:

print '%s is %3d.%d' % ('pi', 3, 14159)

For what it's worth, Python 3 greatly improves the situation by allowing you to specify the separator and terminator for a single print call:

>>> print(1,2,3,4,5)
1 2 3 4 5

>>> print(1,2,3,4,5,end='<<\n')
1 2 3 4 5<<

>>> print(1,2,3,4,5,sep=':',end='<<\n')
1:2:3:4:5<<

Edit (26.11.2018): I've also created Launcher Framework in C# (.NET Framework 3.5), which you can also check to see how launcher should work Available Here

From GitHub:

The blame command is a Git feature, designed to help you determine who made changes to a file.

Despite its negative-sounding name, git blame is actually pretty innocuous; its primary function is to point out who changed which lines in a file, and why. It can be a useful tool to identify changes in your code.

Basically, git-blame is used to show what revision and author last modified each line of a file. It's like checking the history of the development of a file.

You could make it through iframes... I made something, but my only problem for now is syncing those divs to scroll simultaneous... its terrible way, because its like you load 2 websites, but the only way I found... you could also work with divs and overflow I guess...

There doesn't appear to be a way to do basic + body, but you can use FULL and filter the headers you don't want.

RestAdapter adapter = new RestAdapter.Builder()
                          .setEndpoint(syncServer)
                          .setErrorHandler(err)
                          .setConverter(new GsonConverter(gson))
                          .setLogLevel(logLevel)
                          .setLog(new RestAdapter.Log() {
                              @Override
                              public void log(String msg) {
                                  String[] blacklist = {"Access-Control", "Cache-Control", "Connection", "Content-Type", "Keep-Alive", "Pragma", "Server", "Vary", "X-Powered-By"};
                                  for (String bString : blacklist) {
                                      if (msg.startsWith(bString)) {
                                          return;
                                      }
                                  }
                                  Log.d("Retrofit", msg);
                              }
                          }).build();

It appears that when overriding the log, the body is prefixed with a tag similar to

[ 02-25 10:42:30.317 25645:26335 D/Retrofit ]

so it should be easy to log basic + body by adjusting the custom filter. I am using a blacklist, but a whitelist could also be used depending on your needs.

This is easy and very short:

.block {_x000D_
  display: table-row;_x000D_
  vertical-align: middle;_x000D_
}_x000D_
_x000D_
.tile {_x000D_
  display: table-cell;_x000D_
  vertical-align: middle;_x000D_
  text-align: center;_x000D_
  width: 500px;_x000D_
  height: 100px;_x000D_
}

<div class="body">_x000D_
  <span class="tile">_x000D_
    Hello middle world! :)_x000D_
  </span>_x000D_
</div>

Quite and simple without any "having to specify the first element". CSS is more powerful than most think (e.g. the first-child:before is great!). But this is by far the cleanest and most proper way to do this, at least in my opinion it is.

#navigation ul
{
    margin: 0;
    padding: 0;
}

#navigation ul li
{
    list-style-type: none;
    display: inline;
}

#navigation li:not(:first-child):before {
    content: " | ";
}

Now just use a simple unordered list in HTML and it'll populate it for you. HTML should look like this:

<div id="navigation">
    <ul>
        <li><a href="#">Home</a></li>
        <li><a href="#">About Us</a></li>
        <li><a href="#">Support</a></li>
    </ul>
</div><!-- navigation -->

The result will be just like this:

HOME | ABOUT US | SUPPORT

Now you can indefinitely expand and never have to worry about order, changing links, or your first entry. It's all automated and works great!

Create a diagram for existing database schema or its subset as follows:

1. Click File ? Data Modeler ? Import ? Data Dictionary.
2. Select a DB connection (add one if none).
3. Click Next.
4. Check one or more schema names.
5. Click Next.
6. Check one or more objects to import.
7. Click Next.
8. Click Finish.

The ERD is displayed.

Export the diagram as follows:

1. Click File ? Data Modeler ? Print Diagram ? To Image File.
2. Browse to and select the export file location.
3. Click Save.

The diagram is exported. To export in a vector format, use To PDF File, instead. This allows for simplified editing using Inkscape (or other vector image editor).

These instructions may work for SQL Developer 3.2.09.23 to 4.1.3.20.

Just figured this out while playing around.

I found with these solutions to remove focus, caused the ESC key to stop working (ie close the dialog) when first going into the Dialog.

If the dialog opens and you immediately press ESC, it won't close the dialog (if you have that enabled), because the focus is on some hidden field or something, and it is not getting keypress events.

The way I fixed it was to add this to the open event to remove the focus from the first field instead:

$('#myDialog').dialog({
    open: function(event,ui) {
        $(this).parent().focus();
    }
});

This sets focus to the dialog box, which is not visible, and then the ESC key works.

We have an application that allows the user to set "parameters" in the page. What we do is set those params on the URL, using React Router (in conjunction with History) and a library that URI-encodes JavaScript objects into a format that can be used as your query string.

When the user selects an option, we can push the value of that onto the current route with:

history.push({pathname: 'path/', search: '?' + Qs.stringify(params)});

pathname can be the current path. In your case params would look something like:

{
  selectedOption: 5
}

Then at the top level of the React tree, React Router will update the props of that component with a prop of location.search which is the encoded value we set earlier, so there will be something in componentWillReceiveProps like:

params = Qs.parse(nextProps.location.search.substring(1));
this.setState({selectedOption: params.selectedOption});

Then that component and its children will re-render with the updated setting. As the information is on the URL it can be bookmarked (or emailed around - this was our use case) and a refresh will leave the app in the same state. This has been working really well for our application.

Call onBackPressed after overriding it in your activity.

not need to run queries to sidable FKs on sql. If you have a FK from table A to B, you should:

• delete data from table A
• delete data from table B
• insert data on B
• insert data on A

You can also tell the destination not to check constraints

For full control of ANY (non simplest editor, non head of tree) ui elements I recomend use plugin UI Editor for NetBeans

Here's a complete, self-contained example. First, use the following HTML:

<canvas id="example" width="200" height="60"></canvas>
<div id="status"></div>

Then put some squares on the canvas with random background colors:

var example = document.getElementById('example');
var context = example.getContext('2d');
context.fillStyle = randomColor();
context.fillRect(0, 0, 50, 50);
context.fillStyle = randomColor();
context.fillRect(55, 0, 50, 50);
context.fillStyle = randomColor();
context.fillRect(110, 0, 50, 50);

And print each color on mouseover:

$('#example').mousemove(function(e) {
    var pos = findPos(this);
    var x = e.pageX - pos.x;
    var y = e.pageY - pos.y;
    var coord = "x=" + x + ", y=" + y;
    var c = this.getContext('2d');
    var p = c.getImageData(x, y, 1, 1).data; 
    var hex = "#" + ("000000" + rgbToHex(p[0], p[1], p[2])).slice(-6);
    $('#status').html(coord + "<br>" + hex);
});

The code above assumes the presence of jQuery and the following utility functions:

function findPos(obj) {
    var curleft = 0, curtop = 0;
    if (obj.offsetParent) {
        do {
            curleft += obj.offsetLeft;
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
        return { x: curleft, y: curtop };
    }
    return undefined;
}

function rgbToHex(r, g, b) {
    if (r > 255 || g > 255 || b > 255)
        throw "Invalid color component";
    return ((r << 16) | (g << 8) | b).toString(16);
}

function randomInt(max) {
  return Math.floor(Math.random() * max);
}

function randomColor() {
    return `rgb(${randomInt(256)}, ${randomInt(256)}, ${randomInt(256)})`
}

You can specify the -t option (--target) to specify the destination directory. See pip install --help for detailed information. This is the command you need:

pip install -t path_to_your_home package-name

for example, for installing say mxnet, in my $HOME directory, I type:

pip install -t /home/foivos/ mxnet

>>> foo = 'BS1 1AB'
>>> foo.replace(" ", "").rstrip()[:-3].upper()
'BS1'

Similarly to the RTTI, NO-RTTI discussion above, this problem can also occur if you use dynamic_cast and fail to include the object code containing the class implementation.

I ran into this problem building on Cygwin and then porting code to Linux. The make files, directory structure and even the gcc versions (4.8.2) were identical in both cases, but the code linked and operated correctly on Cygwin but failed to link on Linux. Red Hat Cygwin has apparently made compiler/linker modifications that avoid the object code linking requirement.

The Linux linker error message properly directed me to the dynamic_cast line, but earlier messages in this forum had me looking for missing function implementations rather than the actual problem: missing object code. My workaround was to substitute a virtual type function in the base and derived class, e.g. virtual int isSpecialType(), rather than use dynamic_cast. This technique avoids the requirement to link object implementation code just to get dynamic_cast to work properly.

The pop method of dicts (like self.data, i.e. {'a':'aaa','b':'bbb','c':'ccc'}, here) takes two arguments -- see the docs

The second argument, default, is what pop returns if the first argument, key, is absent. (If you call pop with just one argument, key, it raises an exception if that key's absent).

In your example, print b.pop('a',{'b':'bbb'}), this is irrelevant because 'a' is a key in b.data. But if you repeat that line...:

b=a()
print b.pop('a',{'b':'bbb'})
print b.pop('a',{'b':'bbb'})
print b.data

you'll see it makes a difference: the first pop removes the 'a' key, so in the second pop the default argument is actually returned (since 'a' is now absent from b.data).

To delete multiple rows in datagrid, c#

parts of my code:

private void btnDelete_Click(object sender, EventArgs e)
    {
        foreach (DataGridViewRow row in datagrid1.SelectedRows)
        {
            //get key
            int rowId = Convert.ToInt32(row.Cells[0].Value);

            //avoid updating the last empty row in datagrid
            if (rowId > 0)
            {
                //delete 
                aController.Delete(rowId);

                //refresh datagrid
                datagrid1.Rows.RemoveAt(row.Index); 
            }  
        }
    }




 public void Delete(int rowId)
        {
            var toBeDeleted = db.table1.First(c => c.Id == rowId);
            db.table1.DeleteObject(toBeDeleted);
            db.SaveChanges();

        }

Nothing is impossible. Here's a solution that simply sets the value of a text input whenever the value of the <select> changes (rendering has been tested on Firefox and Google Chrome):

.select-editable {position:relative; background-color:white; border:solid grey 1px;  width:120px; height:18px;}_x000D_
.select-editable select {position:absolute; top:0px; left:0px; font-size:14px; border:none; width:120px; margin:0;}_x000D_
.select-editable input {position:absolute; top:0px; left:0px; width:100px; padding:1px; font-size:12px; border:none;}_x000D_
.select-editable select:focus, .select-editable input:focus {outline:none;}

<div class="select-editable">_x000D_
  <select onchange="this.nextElementSibling.value=this.value">_x000D_
    <option value=""></option>_x000D_
    <option value="115x175 mm">115x175 mm</option>_x000D_
    <option value="120x160 mm">120x160 mm</option>_x000D_
    <option value="120x287 mm">120x287 mm</option>_x000D_
  </select>_x000D_
  <input type="text" name="format" value=""/>_x000D_
</div>

The next example adds the user input to the empty option slot of the <select> (thanks to @TomerPeled). It also has a little bit more flexible/variable CSS:

.select-editable {position:relative; width:120px;}_x000D_
.select-editable > * {position:absolute; top:0; left:0; box-sizing:border-box; outline:none;}_x000D_
.select-editable select {width:100%;}_x000D_
.select-editable input {width:calc(100% - 20px); margin:1px; border:none; text-overflow:ellipsis;}

<div class="select-editable">_x000D_
  <select onchange="this.nextElementSibling.value=this.value">_x000D_
    <option value=""></option>_x000D_
    <option value="115x175 mm">115x175 mm</option>_x000D_
    <option value="120x160 mm">120x160 mm</option>_x000D_
    <option value="120x287 mm">120x287 mm</option>_x000D_
  </select>_x000D_
  <input type="text" oninput="this.previousElementSibling.options[0].value=this.value; this.previousElementSibling.options[0].innerHTML=this.value" onchange="this.previousElementSibling.selectedIndex=0" value="" />_x000D_
</div>

DataList

In HTML5 you can also do this with the <input> list attribute and <datalist> element:

<input list="browsers" name="browser">_x000D_
<datalist id="browsers">_x000D_
  <option value="Internet Explorer">_x000D_
  <option value="Firefox">_x000D_
  <option value="Chrome">_x000D_
  <option value="Opera">_x000D_
  <option value="Safari">_x000D_
</datalist>_x000D_
(click once to focus and edit, click again to see option dropdown)

But this acts more like an auto-complete list; once you start typing, only the options that contain the typed string are left as suggestions. Depending on what you want to use it for, this may or may not be practical.

Below is Example of simple dropdown using jstl tag

 <form:select path="cityFrom">  
    <form:option value="Ghaziabad" label="Ghaziabad"/>  
    <form:option value="Modinagar" label="Modinagar"/>  
    <form:option value="Meerut" label="Meerut"/>  
    <form:option value="Amristar" label="Amristar"/>  
 </form:select>

while ($personCount < 10) {
    $result .= ($personCount++)." people ";
}

echo $result;

Let's talk only in code with working examples. I like russ's answer above but to remove any doubt I had, I enhanced it a little bit. I ran it twice, once with the worker thread set to deamon true (deamon thread) and another time set it to false (user thread). It confirms that the deamon thread ends when the main thread terminates.

public class DeamonThreadTest {

public static void main(String[] args) {

    new WorkerThread(false).start();    //set it to true and false and run twice.

    try {
        Thread.sleep(7500);
    } catch (InterruptedException e) {
        // handle here exception
    }

    System.out.println("Main Thread ending");
    }
   }

   class WorkerThread extends Thread {

    boolean isDeamon;

    public WorkerThread(boolean isDeamon) {
        // When false, (i.e. when it's a user thread),
        // the Worker thread continues to run.
        // When true, (i.e. when it's a daemon thread),
        // the Worker thread terminates when the main
        // thread terminates.
        this.isDeamon = isDeamon;
        setDaemon(isDeamon);
    }

    public void run() {
        System.out.println("I am a " + (isDeamon ? "Deamon Thread" : "User Thread (none-deamon)"));

        int counter = 0;

        while (counter < 10) {
            counter++;
            System.out.println("\tworking from Worker thread " + counter++);

            try {
                sleep(5000);
            } catch (InterruptedException e) {
                // handle exception here
            }
        }
        System.out.println("\tWorker thread ends. ");
    }
}

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--example', nargs='?', const=1, type=int)
args = parser.parse_args()
print(args)

% test.py 
Namespace(example=None)
% test.py --example
Namespace(example=1)
% test.py --example 2
Namespace(example=2)

• nargs='?' means 0-or-1 arguments
• const=1 sets the default when there are 0 arguments
• type=int converts the argument to int

If you want test.py to set example to 1 even if no --example is specified, then include default=1. That is, with

parser.add_argument('--example', nargs='?', const=1, type=int, default=1)

then

% test.py 
Namespace(example=1)

You can also use Google PDF viewer for this purpose. As far as I know it's not an official Google feature (am I wrong on this?), but it works for me very nicely and smoothly. You need to upload your PDF somewhere before and just use its URL:

<iframe src="http://docs.google.com/gview?url=http://example.com/mypdf.pdf&embedded=true" style="width:718px; height:700px;" frameborder="0"></iframe>

What is important is that it doesn't need a Flash player, it uses JavaScript.

One has exactly space for 11 bytes, the other for exactly 11 characters. Some charsets such as Unicode variants may use more than one byte per char, therefore the 11 byte field might have space for less than 11 chars depending on the encoding.

. (dot) files are hidden by default on Unix/Linux systems. Most likely, if you know they are .htaccess files, then they are probably in the root folder for the website.

If you are using a command line (terminal) to access, then they will only show up if you use:

ls -a

If you are using a GUI application, look for a setting to "show hidden files" or something similar.

If you still have no luck, and you are on a terminal, you can execute these commands to search the whole system (may take some time):

cd /
find . -name ".htaccess"

This will list out any files it finds with that name.

Remove Object from NSArray with this Method:

-(NSArray *) removeObjectFromArray:(NSArray *) array withIndex:(NSInteger) index {

    [modifyableArray removeObjectAtIndex:index];
    return [[NSArray alloc] initWithArray:modifyableArray];
}

pspg is a simple tool that offers advanced table formatting, horizontal scrolling, search and many more features.

git clone https://github.com/okbob/pspg.git
cd pspg
./configure
make
make install

then make sure to update PAGER variable e.g. in your ~/.bashrc

export PAGER="pspg -s 6" 

where -s stands for color scheme (1-14). If you're using pgdg repositories simply install a package (on Debian-like distribution):

sudo apt install pspg

Here's a CSS-only alternative. I set this up for a search field to get an effect similar to Firefox (& a hundred other apps.)

Here's a fiddle.

HTML

<div class="col-md-4">
  <input class="form-control" type="search" />
  <span class="glyphicon glyphicon-search"></span>
</div>

CSS

.form-control {
  padding-right: 30px;
}

.form-control + .glyphicon {
  position: absolute;
  right: 0;
  padding: 8px 27px;
}

I think the best and simplest solution is (KISS):

double i = 348842;
double i2 = i/60000;
float k = (float) Math.round(i2 * 100) / 100;

// a wrapper closure around executing a string                                  
// can take either a string or a list of strings (for arguments with spaces)    
// prints all output, complains and halts on error                              
def runCommand = { strList ->
  assert ( strList instanceof String ||
           ( strList instanceof List && strList.each{ it instanceof String } ) \
)
  def proc = strList.execute()
  proc.in.eachLine { line -> println line }
  proc.out.close()
  proc.waitFor()

  print "[INFO] ( "
  if(strList instanceof List) {
    strList.each { print "${it} " }
  } else {
    print strList
  }
  println " )"

  if (proc.exitValue()) {
    println "gave the following error: "
    println "[ERROR] ${proc.getErrorStream()}"
  }
  assert !proc.exitValue()
}

I made some small changes to Alex McKay's function/usage that I think make it a little easier to follow why it works and also adheres to the no-use-before-define rule.

First, define this function to use:

const getKeyValue = function<T extends object, U extends keyof T> (obj: T, key: U) { return obj[key] }

In the way I've written it, the generic for the function lists the object first, then the property on the object second (these can occur in any order, but if you specify U extends key of T before T extends object you break the no-use-before-define rule, and also it just makes sense to have the object first and its' property second. Finally, I've used the more common function syntax instead of the arrow operators (=>).

Anyways, with those modifications you can just use it like this:

interface User {
  name: string;
  age: number;
}

const user: User = {
  name: "John Smith",
  age: 20
};

getKeyValue(user, "name")

Which, again, I find to be a bit more readable.

Look at http://ss64.com/nt/if.html for an answer; the command is IF [%1]==[] GOTO NO_ARGUMENT or similar.

For me at least, this happened when I removed a reference to an assembly and added a reference to a newer version of it, which had a different name. In this case, it seems that the old assembly remained in the bin and obj folder, and was not removed with the clean solution operation from Visual Studio (maybe because it is not part of the project anymore). In this case, it was enough to delete the contents of the bin and obj folders of the project where he error happens, from Windows Explorer (or a file management tool). Then, from Visual Studio, clean the solution and rebuild.

using(var tw = new StreamWriter(path, File.Exists(path)))
{
    tw.WriteLine(message);
}

I agree with @annakata that this question needs some more clarification, but here is a very, very basic example of how to setup an onclick event handler for the radio buttons:

<html>
 <head>
  <script type="text/javascript">
    window.onload = function() {

        var ex1 = document.getElementById('example1');
        var ex2 = document.getElementById('example2');
        var ex3 = document.getElementById('example3');

        ex1.onclick = handler;
        ex2.onclick = handler;
        ex3.onclick = handler;

    }

    function handler() {
        alert('clicked');
    }
  </script>
 </head>
 <body>
  <input type="radio" name="example1" id="example1" value="Example 1" />
  <label for="example1">Example 1</label>
  <input type="radio" name="example2" id="example2" value="Example 2" />
  <label for="example1">Example 2</label>
  <input type="radio" name="example3" id="example3" value="Example 3" />
  <label for="example1">Example 3</label>
 </body>
</html>

I have struggled mightily to get the behavior I want. This is the easiest and best way to get TypeScript files to compile on save, to the configuration I want, only THIS file (the saved file). It's a tasks.json and a keybindings.json.

Change from @Controller to @Service to CompteController and add @Service annotation to CompteDAOHib. Let me know if you still face this issue.

As mentioned in multiple answers above you can import the cURL in POSTMAN directly. But if URL is authorized (or is not working for some reason) ill suggest you can manually add all the data points as JSON in your postman body. take the API URL from the cURL.

for the Authorization part- just add an Authorization key and base 64 encoded string as value.

example:

curl -u rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a \ https://api.razorpay.com/v1/orders -X POST \ --data "amount=50000" \ --data "currency=INR" \ --data "receipt=Receipt #20" \ --data "payment_capture=1" https://api.razorpay.com/v1/orders

{ "amount": "5000", "currency": "INR", "receipt": "Receipt #20", "payment_capture": "1" }

Headers: Authorization:Basic cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J where "cnpwX3Rlc3RfWEk5QW5TU0N3RlhjZ0Y6dURjVThLZ3JiQVVnZ3JNS***U056V25J" is the encoded form of "rzp_test_26ccbdbfe0e84b:69b2e24411e384f91213f22a"`

small tip: for encoding, you can easily go to your chrome console (right-click => inspect) and type : btoa("string you want to encode") ( or use postman basic authorization)

You can fire an event yourself in ngOnInit() of your Angular root component and then listen for this event outside of Angular.

This is Dart code (I don't know TypeScript) but should't be to hard to translate

@Component(selector: 'app-element')
@View(
    templateUrl: 'app_element.html',
)
class AppElement implements OnInit {
  ElementRef elementRef;
  AppElement(this.elementRef);

  void ngOnInit() {
    DOM.dispatchEvent(elementRef.nativeElement, new CustomEvent('angular-ready'));
  }
}

I'm running an ASP.NET MVC 5 application on IIS 8.5. I tried all the variations posted here, and this is what my web.config looks like:

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
        <remove name="WebDAVModule"/> <!-- add this -->
    </modules>  
    <handlers>      
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" />
      <remove name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" />
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="WebDAV" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_32bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness32" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-ISAPI-4.0_64bit" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" modules="IsapiModule" scriptProcessor="%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_isapi.dll" preCondition="classicMode,runtimeVersionv4.0,bitness64" responseBufferLimit="0" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE,PATCH,OPTIONS" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers> 
</system.webServer>

I couldn't uninstall WebDav from my Server because I didn't have admin privileges. Also, sometimes I was getting the method not allowed on .css and .js files. In the end, with the configuration above set up everything started working again.

EDIT: I've added one more option for bootstrap sidebars.

There are actually three manners in which you can make a bootstrap 3 sidebar. I tried to keep the code as simple as possible.

Fixed sidebar

Here you can see a demo of a simple fixed sidebar I've developed with the same height as the page

Sidebar in a column

I've also developed a rather simple column sidebar that works in a two or three column page inside a container. It takes the length of the longest column. Here you can see a demo

Dashboard

If you google bootstrap dashboard, you can find multiple suitable dashboard, such as this one. However, most of them require a lot of coding. I've developed a dashboard that works without additional javascript (next to the bootstrap javascript). Here is a demo

For all three examples you off course have to include the jquery, bootstrap css, js and theme.css files.

Slidebar

If you want the sidebar to hide on pressing a button this is also possible with only a little javascript.Here is a demo

I have found a solution. It is just a workaround to my problem but currently the only solution.

ViewPager PagerAdapter not updating the View

public int getItemPosition(Object object) {
   return POSITION_NONE;
}

Does anyone know whether this is a bug or not?

How about this, which I managed to achieve thanks, in part, to this post.

You want to find several files, lets say logs with different names but a pattern (e.g. filename=logfile.DATE), inside several directories with a pattern (e.g. /logsapp1, /logsapp2). Each file has a pattern you want to grep (e.g. "init time"), and you want to have the "init time" of each file, but knowing which file it belongs to.

find ./logsapp* -name logfile* | xargs -I{} grep "init time" {} \dev\null | tee outputfilename.txt

Then the outputfilename.txt would be something like

./logsapp1/logfile.22102015: init time: 10ms
./logsapp1/logfile.21102015: init time: 15ms
./logsapp2/logfile.21102015: init time: 17ms
./logsapp2/logfile.22102015: init time: 11ms

In general

find ./path_pattern/to_files* -name filename_pattern* | xargs -I{} grep "grep_pattern" {} \dev\null | tee outfilename.txt

Explanation:

find command will search the filenames based in the pattern

then, pipe xargs -I{} will redirect the find output to the {}

which will be the input for grep ""pattern" {}

Then the trick to make grep display the filenames \dev\null

and finally, write the output in file with tee outputfile.txt

This worked for me in grep version 9.0.5 build 1989.

$(document).ready(function(){
$('#userForm').on('submit', function(e){
        e.preventDefault();
//I had an issue that the forms were submitted in geometrical progression after the next submit. 
// This solved the problem.
        e.stopImmediatePropagation();
    // show that something is loading
    $('#response').html("<b>Loading data...</b>");

    // Call ajax for pass data to other place
    $.ajax({
    type: 'POST',
    url: 'somephpfile.php',
    data: $(this).serialize() // getting filed value in serialize form
    })
    .done(function(data){ // if getting done then call.

    // show the response
    $('#response').html(data);

    })
    .fail(function() { // if fail then getting message

    // just in case posting your form failed
    alert( "Posting failed." );

    });

    // to prevent refreshing the whole page page
    return false;

    });

int and unsigned int are two distinct integer types. (int can also be referred to as signed int, or just signed; unsigned int can also be referred to as unsigned.)

As the names imply, int is a signed integer type, and unsigned int is an unsigned integer type. That means that int is able to represent negative values, and unsigned int can represent only non-negative values.

The C language imposes some requirements on the ranges of these types. The range of int must be at least -32767 .. +32767, and the range of unsigned int must be at least 0 .. 65535. This implies that both types must be at least 16 bits. They're 32 bits on many systems, or even 64 bits on some. int typically has an extra negative value due to the two's-complement representation used by most modern systems.

Perhaps the most important difference is the behavior of signed vs. unsigned arithmetic. For signed int, overflow has undefined behavior. For unsigned int, there is no overflow; any operation that yields a value outside the range of the type wraps around, so for example UINT_MAX + 1U == 0U.

Any integer type, either signed or unsigned, models a subrange of the infinite set of mathematical integers. As long as you're working with values within the range of a type, everything works. When you approach the lower or upper bound of a type, you encounter a discontinuity, and you can get unexpected results. For signed integer types, the problems occur only for very large negative and positive values, exceeding INT_MIN and INT_MAX. For unsigned integer types, problems occur for very large positive values and at zero. This can be a source of bugs. For example, this is an infinite loop:

for (unsigned int i = 10; i >= 0; i --) [
    printf("%u\n", i);
}

because i is always greater than or equal to zero; that's the nature of unsigned types. (Inside the loop, when i is zero, i-- sets its value to UINT_MAX.)

Maven Dependency Scope

provided : This is much like compile, but indicates you expect the JDK or a container to provide the dependency at runtime. For example, when building a web application for the Java Enterprise Edition, you would set the dependency on the Servlet API and related Java EE APIs to scope provided because the web container provides those classes. This scope is only available on the compilation and test classpath, and is not transitive.

You may be able to find them in one of these locations (depending on the version of Windows you are using).

I wrote a tree library that plays nicely with Java8 and that has no other dependencies. It also provides a loose interpretation of some ideas from functional programming and lets you map/filter/prune/search the entire tree or subtrees.

https://github.com/RutledgePaulV/prune

The implementation doesn't do anything special with indexing and I didn't stray away from recursion, so it's possible that with large trees performance will degrade and you could blow the stack. But if all you need is a straightforward tree of small to moderate depth, I think it works well enough. It provides a sane (value based) definition of equality and it also has a toString implementation that lets you visualize the tree!

A printer doesn't understand pixels, it understand dots (pt in CSS). The best solution is to write an extra CSS for printing, with all of its measures in dots.

Then, in your HTML code, in head section, put:

<link href="style.css" rel="stylesheet" type="text/css" media="screen">
<link href="style_print.css" rel="stylesheet" type="text/css" media="print">

You should also check you JSON (not in DevTools, but on a backend). Angular HttpClient having a hard time parsing JSON with \0 characters and DevTools will ignore then, so it's quite hard to spot in Chrome.

Based on this article

You can use dict.get()

value = d.get(key)

which will return None if key is not in d. You can also provide a different default value that will be returned instead of None:

value = d.get(key, "empty")

RFID Standards:

• 125 Khz (low-frequency) tags are write-once/read-many, and usually only contain a small (permanent) unique identification number.

• 13.56 Mhz (high-frequency) tags are usually read/write, they can typically store about 1 to 2 kilbytes of data in addition to their preset (permanent) unique ID number.

• 860-960 Mhz (ultra-high-frequency) tags are typically read/write and can have much larger information storage capacity (I think that 64 KB is the highest currently available for passive tags) in addition to their preset (permanent) unique ID number.
  
  

More Information

Most read/write tags can be locked to prevent further writing to specific data-blocks in the tag's internal memory, while leaving other blocks unlocked. Different tag manufacturers make their tags differently, though.

Depending on your intended application, you might have to program your own microcontroller to interface with an embedded RFID read/write module using a manufacturer-specific protocol. That's certainly a lot cheaper than buying a complete RFID read/write unit, as they can cost several thousand dollars. With a custom solution, you can build you own unit that does specifically what you want for as little as $200.

This is pretty neat:

head, *tail = [1, 2, 3, 4, 5]
#==> head = 1, tail = [2, 3, 4, 5]

As written in the comments, there's an advantage of not mutating the original list.

If you are using the [WebInvoke(Method="GET")] attribute on the service method, make sure that you spell the method name as "GET" and not "Get" or "get" since it is case sensitive! I had the same error and it took me an hour to figure that one out.

This worked for me.. adding empty view ..

From the C++ FAQ:

[15.1] Why should I use <iostream> instead of the traditional <cstdio>?

Increase type safety, reduce errors, allow extensibility, and provide inheritability.

printf() is arguably not broken, and scanf() is perhaps livable despite being error prone, however both are limited with respect to what C++ I/O can do. C++ I/O (using << and >>) is, relative to C (using printf() and scanf()):

• More type-safe: With <iostream>, the type of object being I/O'd is known statically by the compiler. In contrast, <cstdio> uses "%" fields to figure out the types dynamically.
• Less error prone: With <iostream>, there are no redundant "%" tokens that have to be consistent with the actual objects being I/O'd. Removing redundancy removes a class of errors.
• Extensible: The C++ <iostream> mechanism allows new user-defined types to be I/O'd without breaking existing code. Imagine the chaos if everyone was simultaneously adding new incompatible "%" fields to printf() and scanf()?!
• Inheritable: The C++ <iostream> mechanism is built from real classes such as std::ostream and std::istream. Unlike <cstdio>'s FILE*, these are real classes and hence inheritable. This means you can have other user-defined things that look and act like streams, yet that do whatever strange and wonderful things you want. You automatically get to use the zillions of lines of I/O code written by users you don't even know, and they don't need to know about your "extended stream" class.

On the other hand, printf is significantly faster, which may justify using it in preference to cout in very specific and limited cases. Always profile first. (See, for example, http://programming-designs.com/2009/02/c-speed-test-part-2-printf-vs-cout/)

If using Visual Studio 2010 you can right-click on the project for the service, and select properties. Then select the Web tab. Under the Servers section you can configure the URL. There is also a button to create the virtual directory.

If you're developing for Android there is TextUtils class which may help you:

import android.text.TextUtils;

It is really helps a lot to check equality of Strings.
For example if you need to check Strings s1, s2 equality (which may be nulls) you may use instead of

if( (s1 != null && !s1.equals(s2)) || (s1 == null && s2 != null) ) 
{ ... }

this simple method:

if( !TextUtils.equals(s1, s2) )
{ ... }

As for initial question - for replacement it's easier to use s1.replace().

If your xml is written by java.lang.String you can just using HttpClient in this way

    public void post() throws Exception{
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://www.baidu.com");
        String xml = "<xml>xxxx</xml>";
        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        String result = EntityUtils.toString(response.getEntity());
    }

pay attention to the Exceptions.

BTW, the example is written by the httpclient version 4.x

SELECT [UserID] FROM [User] u LEFT JOIN (
SELECT [TailUser], [Weight] FROM [Edge] WHERE [HeadUser] = 5043) t on t.TailUser=u.USerID

The table is only dropped and re-created in cases where that's the only way SQL Server's Management Studio has been programmed to know how to do it.

There are certainly cases where it will do that when it doesn't need to, but there will also be cases where edits you make in Management Studio will not drop and re-create because it doesn't have to.

The problem is that enumerating all of the cases and determining which side of the line they fall on will be quite tedious.

This is why I like to use ALTER TABLE in a query window, instead of visual designers that hide what they're doing (and quite frankly have bugs) - I know exactly what is going to happen, and I can prepare for cases where the only possibility is to drop and re-create the table (which is some number less than how often SSMS will do that to you).

Let's understand in simple words

• PRI - It's a primary key, and used to identify records uniquely.
• UNI - It's a unique key, and also used to identify records uniquely. It looks similar like primary key but a table can have multiple unique keys and unique key can have one null value, on the other hand table can have only one primary key and can't store null as a primary key.
• MUL - It's doesn't have unique constraint and table can have multiple MUL columns.

Note: These keys have more depth as a concept but this is good to start.

After 5.0.13, in stored procedures, you can use dynamic SQL:

delimiter // 
CREATE PROCEDURE dynamic(IN tbl CHAR(64), IN col CHAR(64))
BEGIN
    SET @s = CONCAT('SELECT ',col,' FROM ',tbl );
    PREPARE stmt FROM @s;
    EXECUTE stmt;
    DEALLOCATE PREPARE stmt;
END
//
delimiter ;

Dynamic SQL does not work in functions or triggers. See the MySQL documentation for more uses.

DateTime.Now returns a DateTime value that consists of the local date and time of the computer where the code is running. It has DateTimeKind.Local assigned to its Kind property. It is equivalent to calling any of the following:

• DateTime.UtcNow.ToLocalTime()
• DateTimeOffset.UtcNow.LocalDateTime
• DateTimeOffset.Now.LocalDateTime
• TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local)
• TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local)

DateTime.Today returns a DateTime value that has the same year, month, and day components as any of the above expressions, but with the time components set to zero. It also has DateTimeKind.Local in its Kind property. It is equivalent to any of the following:

• DateTime.Now.Date
• DateTime.UtcNow.ToLocalTime().Date
• DateTimeOffset.UtcNow.LocalDateTime.Date
• DateTimeOffset.Now.LocalDateTime.Date
• TimeZoneInfo.ConvertTime(DateTime.UtcNow, TimeZoneInfo.Local).Date
• TimeZoneInfo.ConvertTimeFromUtc(DateTime.UtcNow, TimeZoneInfo.Local).Date

Note that internally, the system clock is in terms of UTC, so when you call DateTime.Now it first gets the UTC time (via the GetSystemTimeAsFileTime function in the Win32 API) and then it converts the value to the local time zone. (Therefore DateTime.Now.ToUniversalTime() is more expensive than DateTime.UtcNow.)

Also note that DateTimeOffset.Now.DateTime will have similar values to DateTime.Now, but it will have DateTimeKind.Unspecified rather than DateTimeKind.Local - which could lead to other errors depending on what you do with it.

So, the simple answer is that DateTime.Today is equivalent to DateTime.Now.Date.
But IMHO - You shouldn't use either one of these, or any of the above equivalents.

When you ask for DateTime.Now, you are asking for the value of the local calendar clock of the computer that the code is running on. But what you get back does not have any information about that clock! The best that you get is that DateTime.Now.Kind == DateTimeKind.Local. But whose local is it? That information gets lost as soon as you do anything with the value, such as store it in a database, display it on screen, or transmit it using a web service.

If your local time zone follows any daylight savings rules, you do not get that information back from DateTime.Now. In ambiguous times, such as during a "fall-back" transition, you won't know which of the two possible moments correspond to the value you retrieved with DateTime.Now. For example, say your system time zone is set to Mountain Time (US & Canada) and you ask for DateTime.Now in the early hours of November 3rd, 2013. What does the result 2013-11-03 01:00:00 mean? There are two moments of instantaneous time represented by this same calendar datetime. If I were to send this value to someone else, they would have no idea which one I meant. Especially if they are in a time zone where the rules are different.

The best thing you could do would be to use DateTimeOffset instead:

// This will always be unambiguous.
DateTimeOffset now = DateTimeOffset.Now;

Now for the same scenario I described above, I get the value 2013-11-03 01:00:00 -0600 before the transition, or 2013-11-03 01:00:00 -0700 after the transition. Anyone looking at these values can tell what I meant.

I wrote a blog post on this very subject. Please read - The Case Against DateTime.Now.

Also, there are some places in this world (such as Brazil) where the "spring-forward" transition happens exactly at Midnight. The clocks go from 23:59 to 01:00. This means that the value you get for DateTime.Today on that date, does not exist! Even if you use DateTimeOffset.Now.Date, you are getting the same result, and you still have this problem. It is because traditionally, there has been no such thing as a Date object in .Net. So regardless of how you obtain the value, once you strip off the time - you have to remember that it doesn't really represent "midnight", even though that's the value you're working with.

If you really want a fully correct solution to this problem, the best approach is to use NodaTime. The LocalDate class properly represents a date without a time. You can get the current date for any time zone, including the local system time zone:

using NodaTime;
...

Instant now = SystemClock.Instance.Now;

DateTimeZone zone1 = DateTimeZoneProviders.Tzdb.GetSystemDefault();
LocalDate todayInTheSystemZone = now.InZone(zone1).Date;

DateTimeZone zone2 = DateTimeZoneProviders.Tzdb["America/New_York"];
LocalDate todayInTheOtherZone = now.InZone(zone2).Date;

If you don't want to use Noda Time, there is now another option. I've contributed an implementation of a date-only object to the .Net CoreFX Lab project. You can find the System.Time package object in their MyGet feed. Once added to your project, you will find you can do any of the following:

using System;
...

Date localDate = Date.Today;

Date utcDate = Date.UtcToday;

Date tzSpecificDate = Date.TodayInTimeZone(anyTimeZoneInfoObject);

another way is, you assign a column value for a given row based on the index position of a row, the index position always starts with zero, and the last index position is the length of the dataframe:

df["COL_NAME"].iloc[0]=x

You can pass a variable to a function by reference. This function will be able to modify the original variable.

You can define the passage by reference in the function definition:

<?php
function changeValue(&$var)
{
    $var++;
}

$result=5;
changeValue($result);

echo $result; // $result is 6 here
?>

I had a workaround for this problem. I created dll project with viewer in vs2015 and used this dll in vs2017. Report showing perfectly.

The open SPF wizard from the previous answer is no longer available, neither the one from Microsoft.

If you're not using AngularJS UI Bootstrap, here's how I did it.

I created a directive that will hold that entire element of your modal, and recompile the element to inject your scope into it.

angular.module('yourApp', []).
directive('myModal',
       ['$rootScope','$log','$compile',
function($rootScope,  $log,  $compile) {
    var _scope = null;
    var _element = null;
    var _onModalShow = function(event) {
        _element.after($compile(event.target)(_scope));
    };

    return {
        link: function(scope, element, attributes) {
            _scope = scope;
            _element = element;
            $(element).on('show.bs.modal',_onModalShow);
        }
    };
}]);

I'm assuming your modal template is inside the scope of your controller, then add directive my-modal to your template. If you saved the clicked user to $scope.aModel, the original template will now work.

Note: The entire scope is now visible to your modal so you can also access $scope.users in it.

<div my-modal id="encouragementModal" class="modal hide fade">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal"
      aria-hidden="true">&times;</button>
    <h3>Confirm encouragement?</h3>
  </div>
  <div class="modal-body">
      Do you really want to encourage <b>{{aModel.userName}}</b>?
  </div>
  <div class="modal-footer">
    <button class="btn btn-info"
      ng-click="encourage('${createLink(uri: '/encourage/')}',{{aModel.userName}})">
      Confirm
    </button>
    <button class="btn" data-dismiss="modal" aria-hidden="true">Never Mind</button>
  </div>
</div>

GitLab's "merge request" feature is equivalent to GitHub's "pull request" feature. Both are means of pulling changes from another branch or fork into your branch and merging the changes with your existing code. They are useful tools for code review and change management.

An article from GitLab discusses the differences in naming the feature:

Merge or pull requests are created in a git management application and ask an assigned person to merge two branches. Tools such as GitHub and Bitbucket choose the name pull request since the first manual action would be to pull the feature branch. Tools such as GitLab and Gitorious choose the name merge request since that is the final action that is requested of the assignee. In this article we'll refer to them as merge requests.

A "merge request" should not be confused with the git merge command. Neither should a "pull request" be confused with the git pull command. Both git commands are used behind the scenes in both pull requests and merge requests, but a merge/pull request refers to a much broader topic than just these two commands.

Using return; will work just fine. It will not prevent the full loop from completing. It will only stop executing the current iteration of the forEach loop.

Try the following little program:

public static void main(String[] args) {
    ArrayList<String> stringList = new ArrayList<>();
    stringList.add("a");
    stringList.add("b");
    stringList.add("c");

    stringList.stream().forEach(str -> {
        if (str.equals("b")) return; // only skips this iteration.

        System.out.println(str);
    });
}

Output:

a
c

Notice how the return; is executed for the b iteration, but c prints on the following iteration just fine.

Why does this work?

The reason the behavior seems unintuitive at first is because we are used to the return statement interrupting the execution of the whole method. So in this case, we expect the main method execution as a whole to be halted.

However, what needs to be understood is that a lambda expression, such as:

str -> {
    if (str.equals("b")) return;

    System.out.println(str);
}

... really needs to be considered as its own distinct "method", completely separate from the main method, despite it being conveniently located within it. So really, the return statement only halts the execution of the lambda expression.

The second thing that needs to be understood is that:

stringList.stream().forEach()

... is really just a normal loop under the covers that executes the lambda expression for every iteration.

With these 2 points in mind, the above code can be rewritten in the following equivalent way (for educational purposes only):

public static void main(String[] args) {
    ArrayList<String> stringList = new ArrayList<>();
    stringList.add("a");
    stringList.add("b");
    stringList.add("c");

    for(String s : stringList) {
        lambdaExpressionEquivalent(s);
    }
}

private static void lambdaExpressionEquivalent(String str) {
    if (str.equals("b")) {
        return;
    }

    System.out.println(str);
}

With this "less magic" code equivalent, the scope of the return statement becomes more apparent.

Although I am commenting late. But I have used this method to do the job. Here when I am running my spring application I am providing the application yaml file via -Dspring.config.location=file:/location-to-file/config-server-vault-application.yml which contains all of my properties

config-server-vault-application.yml

  port: 8888

    trust-store: /trust-store/config-server-trust-store.jks
    trust-store-password: config-server
    trust-store-type: pkcs12

@SpringBootApplication
public class ConfigServerApplication {

 public static void main(String[] args) throws IOException {
    setUpTrustStoreForApplication();
    SpringApplication.run(ConfigServerApplication.class, args);
 }

 private static void setUpTrustStoreForApplication() throws IOException {
    YamlPropertySourceLoader loader = new YamlPropertySourceLoader();
    List<PropertySource<?>> applicationYamlPropertySource = loader.load(
            "config-application-properties", new UrlResource(System.getProperty("spring.config.location")));
    Map<String, Object> source = ((MapPropertySource) applicationYamlPropertySource.get(0)).getSource();
    System.setProperty("javax.net.ssl.trustStore", source.get("server.ssl.trust-store").toString());
    System.setProperty("javax.net.ssl.trustStorePassword", source.get("server.ssl.trust-store-password").toString());
  }
}

If you know the name of your constraint then you can directly use the command like

alter table users drop constraint constraint_name;

If you don't know the constraint name, you can get the constraint by using this command

select constraint_name,constraint_type from user_constraints where table_name = 'YOUR TABLE NAME';

This is a good solution. The best part is on the SQL side – fine tuning to any level is easy.

I used MySql and MySql Workbench to Cascade on delete for the Required Foreign KEY.

ALTER TABLE schema.joined_table 
ADD CONSTRAINT UniqueKey
FOREIGN KEY (key2)
REFERENCES schema.table1 (id)
ON DELETE CASCADE;

Well instead of checking both, you could do if(stream_resolve_include_path($folder)!==false). It is slower but kills two birds in one shot.

Another option is to simply ignore the E_WARNING, not by using @mkdir(...); (because that would simply waive all possible warnings, not just the directory already exists one), but by registering a specific error handler before doing it:

namespace com\stackoverflow;

set_error_handler(function($errno, $errm) { 
    if (strpos($errm,"exists") === false) throw new \Exception($errm); //or better: create your own FolderCreationException class
});
mkdir($folder);
/* possibly more mkdir instructions, which is when this becomes useful */
restore_error_handler();

If you just need this for debugging to see how the XML looks like, then instead of print(xml.etree.ElementTree.tostring(e)) you can use dump like this:

xml.etree.ElementTree.dump(e)

And this works both with Element and ElementTree objects as e, so there should be no need for getroot.

The documentation of dump says:

xml.etree.ElementTree.dump(elem)

Writes an element tree or element structure to sys.stdout. This function should be used for debugging only.

The exact output format is implementation dependent. In this version, it’s written as an ordinary XML file.

elem is an element tree or an individual element.

Changed in version 3.8: The dump() function now preserves the attribute order specified by the user.

Try this:

switch (val)
{
    case VAL:
    {
        int newVal = 42;
    }
    break;
}

2018 Update

I just had an app rejected for this reason and a very quick resolution was simply to change from using an action sheet to an alert.

Worked a charm and passed the App Store testers just fine.

May not be a suitable answer for everyone but I hope this helps some of you out of a pickle quickly.

In addition to all the other answers I'd like to note that if you want to write that number as a literal in your Java code, you'll need to append a L or l to tell the compiler that it's a long constant:

long l1 = 9999999999;  // this won't compile
long l2 = 9999999999L; // this will work

An Instant is what it says: a specific instant in time - it does not have the notion of date and time (the time in New York and Tokyo is not the same at a given instant).

To print it as a date/time, you first need to decide which timezone to use. For example:

System.out.println(LocalDateTime.ofInstant(i, ZoneOffset.UTC));

This will print the date/time in iso format: 2015-06-02T10:15:02.325

If you want a different format you can use a formatter:

LocalDateTime datetime = LocalDateTime.ofInstant(i, ZoneOffset.UTC);
String formatted = DateTimeFormatter.ofPattern("yyyy-MM-dd hh:mm:ss").format(datetime);
System.out.println(formatted);

What you have is a fairly unusual use of the ternary operator. Usually it is used as an expression, not a statement, inside of some other operation, e.g.:

var y = (x == 2 ? "yes" : "no");

So, for readability (because what you are doing is unusual), and because it avoids the "else" that you don't want, I would suggest:

if (x==2) doSomething();

The real rule is: Don't throw away exceptions. The objectivity of the author of your quote is questionable, as evidenced by the fact that it ends with

or I will stab you

Of course, be aware that signals (by default) throw exceptions, and normally long-running processes are terminated through a signal, so catching Exception and not terminating on signal exceptions will make your program very hard to stop. So don't do this:

#! /usr/bin/ruby

while true do
  begin
    line = STDIN.gets
    # heavy processing
  rescue Exception => e
    puts "caught exception #{e}! ohnoes!"
  end
end

No, really, don't do it. Don't even run that to see if it works.

However, say you have a threaded server and you want all exceptions to not:

1. be ignored (the default)
2. stop the server (which happens if you say thread.abort_on_exception = true).

Then this is perfectly acceptable in your connection handling thread:

begin
  # do stuff
rescue Exception => e
  myLogger.error("uncaught #{e} exception while handling connection: #{e.message}")
    myLogger.error("Stack trace: #{backtrace.map {|l| "  #{l}\n"}.join}")
end

The above works out to a variation of Ruby's default exception handler, with the advantage that it doesn't also kill your program. Rails does this in its request handler.

Signal exceptions are raised in the main thread. Background threads won't get them, so there is no point in trying to catch them there.

This is particularly useful in a production environment, where you do not want your program to simply stop whenever something goes wrong. Then you can take the stack dumps in your logs and add to your code to deal with specific exception further down the call chain and in a more graceful manner.

Note also that there is another Ruby idiom which has much the same effect:

a = do_something rescue "something else"

In this line, if do_something raises an exception, it is caught by Ruby, thrown away, and a is assigned "something else".

Generally, don't do that, except in special cases where you know you don't need to worry. One example:

debugger rescue nil

The debugger function is a rather nice way to set a breakpoint in your code, but if running outside a debugger, and Rails, it raises an exception. Now theoretically you shouldn't be leaving debug code lying around in your program (pff! nobody does that!) but you might want to keep it there for a while for some reason, but not continually run your debugger.

Note:

1. If you've run someone else's program that catches signal exceptions and ignores them, (say the code above) then:

   • in Linux, in a shell, type pgrep ruby, or ps | grep ruby, look for your offending program's PID, and then run kill -9 <PID>.
   • in Windows, use the Task Manager (CTRL-SHIFT-ESC), go to the "processes" tab, find your process, right click it and select "End process".

2. If you are working with someone else's program which is, for whatever reason, peppered with these ignore-exception blocks, then putting this at the top of the mainline is one possible cop-out:

   %W/INT QUIT TERM/.each { |sig| trap sig,"SYSTEM_DEFAULT" }
   

   This causes the program to respond to the normal termination signals by immediately terminating, bypassing exception handlers, with no cleanup. So it could cause data loss or similar. Be careful!

3. If you need to do this:

   begin
     do_something
   rescue Exception => e
     critical_cleanup
     raise
   end
   

   you can actually do this:

   begin
     do_something
   ensure
     critical_cleanup
   end
   

   In the second case, critical cleanup will be called every time, whether or not an exception is thrown.

There is a hidden cost in removing elements from an ArrayList. Each time you delete an element, you need to move the elements to fill the "hole". On average, this will take N / 2 assignments for a list with N elements.

So removing M elements from an N element ArrayList is O(M * N) on average. An O(N) solution involves creating a new list. For example.

List data = ...;
List newData = new ArrayList(data.size()); 

for (Iterator i = data.iterator(); i.hasNext(); ) {
    Object element = i.next();

    if ((...)) {
        newData.add(element);
    }
}

If N is large, my guess is that this approach will be faster than the remove approach for values of M as small as 3 or 4.

But it is important to create newList large enough to hold all elements in list to avoid copying the backing array when it is expanded.

I hypothesize that given an element where all of its children are ordered on the document sequentially, the fastest way should be to do a binary search, comparing the document positions of the elements. However, as introduced in the conclusion the hypothesis is rejected. The more elements you have, the greater the potential for performance. For example, if you had 256 elements, then (optimally) you would only need to check just 16 of them! For 65536, only 256! The performance grows to the power of 2! See more numbers/statistics. Visit Wikipedia

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndex', {
      get: function() {
        var searchParent = this.parentElement;
        if (!searchParent) return -1;
        var searchArray = searchParent.children,
            thisOffset = this.offsetTop,
            stop = searchArray.length,
            p = 0,
            delta = 0;
        
        while (searchArray[p] !== this) {
            if (searchArray[p] > this)
                stop = p + 1, p -= delta;
            delta = (stop - p) >>> 1;
            p += delta;
        }
        
        return p;
      }
    });
})(window.Element || Node);

Then, the way that you use it is by getting the 'parentIndex' property of any element. For example, check out the following demo.

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndex', {
      get: function() {
        var searchParent = this.parentNode;
        if (searchParent === null) return -1;
        var childElements = searchParent.children,

Limitations

• This implementation of the solution will not work in IE8 and below.

Binary VS Linear Search On 200,000 elements (might crash some mobile browsers, BEWARE!):

• In this test, we will see how long it takes for a linear search to find the middle element VS a binary search. Why the middle element? Because it is at the average location of all the other locations, so it best represents all of the possible locations.

Binary Search

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndexBinarySearch', {
      get: function() {
        var searchParent = this.parentNode;
        if (searchParent === null) return -1;
        var childElements = searchParent.children,
            lo = -1, mi, hi = childElements.length;
        while (1 + lo !== hi) {
            mi = (hi + lo) >> 1;
            if (!(this.compareDocumentPosition(childElements[mi]) & 0x2)) {
                hi = mi;
                continue;
            }
            lo = mi;
        }
        return childElements[hi] === this ? hi : -1;
      }
    });
})(window.Element || Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var child=test.children.item(99.9e+3);
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=200 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99.9e+3+i+Math.random())).parentIndexBinarySearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the binary search ' + ((end-start)*10).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
}, 125);

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

Backwards (`lastIndexOf`) Linear Search

(function(t){"use strict";var e=Array.prototype.lastIndexOf;Object.defineProperty(t.prototype,"parentIndexLinearSearch",{get:function(){return e.call(t,this)}})})(window.Element||Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var child=test.children.item(99e+3);
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=2000 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99e+3+i+Math.random())).parentIndexLinearSearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the backwards linear search ' + (end-start).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

Forwards (`indexOf`) Linear Search

(function(t){"use strict";var e=Array.prototype.indexOf;Object.defineProperty(t.prototype,"parentIndexLinearSearch",{get:function(){return e.call(t,this)}})})(window.Element||Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var child=test.children.item(99e+3);
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=2000 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99e+3+i+Math.random())).parentIndexLinearSearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the forwards linear search ' + (end-start).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

PreviousElementSibling Counter Search

Counts the number of PreviousElementSiblings to get the parentIndex.

(function(constructor){
   'use strict';
    Object.defineProperty(constructor.prototype, 'parentIndexSiblingSearch', {
      get: function() {
        var i = 0, cur = this;
        do {
            cur = cur.previousElementSibling;
            ++i;
        } while (cur !== null)
        return i; //Returns 3
      }
    });
})(window.Element || Node);
test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var child=test.children.item(99.95e+3);
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=100 + end; i-- !== end; )
    console.assert( test.children.item(
        Math.round(99.95e+3+i+Math.random())).parentIndexSiblingSearch );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the PreviousElementSibling search ' + ((end-start)*20).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden;white-space:pre></div>

No Search

For benchmarking what the result of the test would be if the browser optimized out the searching.

test.innerHTML = '<div> </div> '.repeat(200e+3);
// give it some time to think:
requestAnimationFrame(function(){
  var start=performance.now(), end=Math.round(Math.random());
  for (var i=2000 + end; i-- !== end; )
    console.assert( true );
  var end=performance.now();
  setTimeout(function(){
    output.textContent = 'It took the no search ' + (end-start).toFixed(2) + 'ms to find the 999 thousandth to 101 thousandth children in an element with 200 thousand children.';
    test.remove();
    test = null; // free up reference
  }, 125);
});

<output id=output> </output><br />
<div id=test style=visibility:hidden></div>

The Conculsion

However, after viewing the results in Chrome, the results are the opposite of what was expected. The dumber forwards linear search was a surprising 187 ms, 3850%, faster than the binary search. Evidently, Chrome somehow magically outsmarted the console.assert and optimized it away, or (more optimistically) Chrome internally uses numerical indexing system for the DOM, and this internal indexing system is exposed through the optimizations applied to Array.prototype.indexOf when used on a HTMLCollection object.

import sys
for x in range(10000):
    print "HAPPY >> %s <<\r" % str(x),
    sys.stdout.flush()

Try using android:layout_gravity for ImageView:

android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_gravity="center_vertical|center_horizontal"
android:layout_weight="1"

The example above worked for me.

I doubt the standard library supports this.

But you can use the google maps utility library:

http://code.google.com/p/google-maps-utility-library-v3/wiki/Libraries#MarkerWithLabel

var myLatlng = new google.maps.LatLng(-25.363882,131.044922);

var myOptions = {
    zoom: 8,
    center: myLatlng,
    mapTypeId: google.maps.MapTypeId.ROADMAP
  };

map = new google.maps.Map(document.getElementById('map_canvas'), myOptions);

var marker = new MarkerWithLabel({
   position: myLatlng,
   map: map,
   draggable: true,
   raiseOnDrag: true,
   labelContent: "A",
   labelAnchor: new google.maps.Point(3, 30),
   labelClass: "labels", // the CSS class for the label
   labelInBackground: false
 });

The basics about marker can be found here: https://developers.google.com/maps/documentation/javascript/overlays#Markers

Reset - On the commit-level, resetting is a way to move the tip of a branch to a different commit. This can be used to remove commits from the current branch.

Revert - Reverting undoes a commit by creating a new commit. This is a safe way to undo changes, as it has no chance of re-writing the commit history. Contrast this with git reset, which does alter the existing commit history. For this reason, git revert should be used to undo changes on a public branch, and git reset should be reserved for undoing changes on a private branch.

You can have a look on this link- Reset, Checkout and Revert

An input element does not support the target attribute. The target attribute is for a tags and that is where it should be used.

Please check once the database selected are not because some times database is not selected

Check

mysql_select_db('database name ')or DIE('Database name is not available!');

before MySQL query and then go to next step

$result = mysql_query('SELECT * FROM Users WHERE UserName LIKE $username');

f($result === FALSE) {
    die(mysql_error());

Update! You can access the Android filesystem via Android Device Monitor. In Android Studio go to Tools >> Android >> Android Device Monitor.

Note that you can run your app in the simulator while using the Android Device Monitor. But you cannot debug you app while using the Android Device Monitor.
