Updated answer

Here is how to change the box model used by the input/textarea/select elements so that they all behave the same way. You need to use the box-sizing property which is implemented with a prefix for each browser

-ms-box-sizing:content-box;
-moz-box-sizing:content-box;
-webkit-box-sizing:content-box; 
box-sizing:content-box;

This means that the 2px difference we mentioned earlier does not exist..

example at http://www.jsfiddle.net/gaby/WaxTS/5/

note: On IE it works from version 8 and upwards..

Original

if you reset their borders then the select element will always be 2 pixels less than the input elements..

example: http://www.jsfiddle.net/gaby/WaxTS/2/

Any way you mentioned /root/.m2/settings.xml.

But in my Case i missed the settings.xml to configure in the maven preferences. so that maven will search for the relative_path pom.xml from the remote_repository which is configured in settings.xml

Historically, it's been impossible to make these things disappear as they are user settings and not considered part of the page you have control over.

However, as of 2017, the @page at-rule has been standardized, which can be used to hide the page title and date in modern browsers:

@page { size: auto;  margin: 0mm; }

Print headers/footers and print margins

When printing Web documents, margins are set in the browser's Page Setup (or Print Setup) dialog box. These margin settings, although set within the browser, are controlled at the operating system/printer driver level and are not controllable at the HTML/CSS/DOM level. (For CSS-controlled printed page headers and footers see Printing Headers .)

The settings must be big enough to encompass the printer's physical non-printing areas. Further, they must be big enough to encompass the header and footer that the browser is usually configured to print (typically the page title, page number, URL and date). Note that these headers and footers, although specified by the browser and usually configurable through user preferences, are not part of the Web page itself and therefore are not controllable by CSS. In CSS terms, they fall outside the Page Box CSS2.1 Section 13.2.

... i.e. setting a margin of 0 hides the page title because the title is printed in the margin.

In SQL Server Management Studio (SSMS):

You can also right click your database in the Object Explorer and go to Properties. From there, go to Options. Scroll all the way down and set Restrict Access to SINGLE_USER. Change your database name, then go back in and set it back to MULTI_USER.

If you use Spring you can use DataSourceInitializer:

@Bean
public DataSourceInitializer dataSourceInitializer(@Qualifier("dataSource") final DataSource dataSource) {
    ResourceDatabasePopulator resourceDatabasePopulator = new ResourceDatabasePopulator();
    resourceDatabasePopulator.addScript(new ClassPathResource("/data.sql"));
    DataSourceInitializer dataSourceInitializer = new DataSourceInitializer();
    dataSourceInitializer.setDataSource(dataSource);
    dataSourceInitializer.setDatabasePopulator(resourceDatabasePopulator);
    return dataSourceInitializer;
}

Used to set up a database during initialization and clean up a database during destruction.

https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/jdbc/datasource/init/DataSourceInitializer.html

You can use format strings as well.

string time = DateTime.Now.ToString("hh:mm:ss"); // includes leading zeros
string date = DateTime.Now.ToString("dd/MM/yy"); // includes leading zeros

or some shortcuts if the format works for you

string time = DateTime.Now.ToShortTimeString();
string date = DateTime.Now.ToShortDateString();

Either should work.

object[,] valueArray = (object[,])excelRange.get_Value(XlRangeValueDataType.xlRangeValueDefault);

//Get the column names
for (int k = 0; k < valueArray.GetLength(1); )
{
    //add columns to the data table.
    dt.Columns.Add((string)valueArray[1,++k]);
}

//Load data into data table
object[] singleDValue = new object[valueArray.GetLength(1)];
//value array first row contains column names. so loop starts from 1 instead of 0
for (int i = 1; i < valueArray.GetLength(0); i++)
{
    Console.WriteLine(valueArray.GetLength(0) + ":" + valueArray.GetLength(1));
    for (int k = 0; k < valueArray.GetLength(1); )
    {
        singleDValue[k] = valueArray[i+1, ++k];
    }
    dt.LoadDataRow(singleDValue, System.Data.LoadOption.PreserveChanges);
}

let x be an object then you can do it two ways

x.attr_name = s 
setattr(x, 'attr_name', s)

I've created library to traverse and edit deep nested JS objects. Check out API here: https://github.com/dominik791

You can also play with the library interactively using demo app: https://dominik791.github.io/obj-traverse-demo/

Examples of usage: You should always have root object which is the first parameter of each method:

var rootObj = {
  name: 'rootObject',
  children: [
    {
      'name': 'child1',
       children: [ ... ]
    },
    {
       'name': 'child2',
       children: [ ... ]
    }
  ]
};

The second parameter is always the name of property that holds nested objects. In above case it would be 'children'.

The third parameter is an object that you use to find object/objects that you want to find/modify/delete. For example if you're looking for object with id equal to 1, then you will pass { id: 1} as the third parameter.

And you can:

1. findFirst(rootObj, 'children', { id: 1 }) to find first object with id === 1
2. findAll(rootObj, 'children', { id: 1 }) to find all objects with id === 1
3. findAndDeleteFirst(rootObj, 'children', { id: 1 }) to delete first matching object
4. findAndDeleteAll(rootObj, 'children', { id: 1 }) to delete all matching objects

replacementObj is used as the last parameter in two last methods:

1. findAndModifyFirst(rootObj, 'children', { id: 1 }, { id: 2, name: 'newObj'}) to change first found object with id === 1 to the { id: 2, name: 'newObj'}
2. findAndModifyAll(rootObj, 'children', { id: 1 }, { id: 2, name: 'newObj'}) to change all objects with id === 1 to the { id: 2, name: 'newObj'}

SQLite 3

Using getMetaData();

DatabaseMetaData md = conn.getMetaData();
ResultSet rset = md.getColumns(null, null, "your_table_name", null);

System.out.println("your_table_name");
while (rset.next())
{
    System.out.println("\t" + rset.getString(4));
}

EDIT: This works with PostgreSQL as well

Changing the value property does not change the defaultValue. In the code (retrieved with .html() or innerHTML) the value attribute will contain the defaultValue, not the value property.

Try this:

SELECT * FROM USERS LIMIT 10;

You can hide the modal and popup the window to review the carts in validateShipping() function itself.

function validateShipping(){
...
...
$('#product-options').modal('hide');
//pop the window to select items
}

r+ is used for reading, and writing mode. b is for binary. r+b mode is open the binary file in read or write mode.
You can read more here.

@list($url) = explode("?", $url, 2);

If you are using python2.7 or above you can use the ability of assertRaises to be use as a context manager and do:

with self.assertRaises(TypeError):
    self.testListNone[:1]

If you are using python2.6 another way beside the one given until now is to use unittest2 which is a back port of unittest new feature to python2.6, and you can make it work using the code above.

N.B: I'm a big fan of the new feature (SkipTest, test discovery ...) of unittest so I intend to use unittest2 as much as I can. I advise to do the same because there is a lot more than what unittest come with in python2.6 <.

NUMBER (precision, scale)

If a precision is not specified, the column stores values as given. If no scale is specified, the scale is zero.

In addition to Gilson PJ answer:

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

with

"scripts": {
    "build": "NODE_ENV=production webpack -p --config ./webpack.production.config.js"
},

cause that the it tries to uglify your code twice. See https://webpack.github.io/docs/cli.html#production-shortcut-p for more information.

You can fix this by removing the UglifyJsPlugin from plugins-array or add the OccurrenceOrderPlugin and remove the "-p"-flag. so one possible solution would be

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.OccurrenceOrderPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

and

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

You should use let keyword as to declare local variables e.g *ngFor="let talk of talks"

If anyone is looking to grab the scope off of a 'controller as' element,.. something like this:

<div id="firstctrl" ng-controller="firstCtrl as vm">  

use the following:

var vm = angular.element(document.querySelector('#firstctrl')).scope().vm;

I cloned the repository with HTTPS URL instead of SSH URL hence even after adding the SSH Key it was asking me for password on Bash Shell.

I just edited the ./.git/config file and changed the value of url variable by simply replacing the https:// to ssh://

E.g.

[core]
        ...
        ...
        ...
[remote "origin"]
        url = https://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

Changed to:

[core]
        ...
        ...
        ...
[remote "origin"]
        url = ssh://<username>@bitbucket.org/<username>/<repository_name>.git
        fetch = +refs/heads/*:refs/remotes/origin/*
        ...
        ...
        ...

I know this is a little old, but for anyone stumbling across this page should know there is a difference between \n and \r\n.

The \r\n gives a CRLF end of line and the \n gives an LF end of line character. There is very little difference to the eye in general.

Create a .txt from the string and then try and open in notepad (normal not notepad++) and you will notice the difference

SHA,PCT,PRACTICE,BNF CODE,BNF NAME,ITEMS,NIC,ACT COST,QUANTITY,PERIOD

The above is using 'CRLF' and the below is what 'LF only' would look like (There is a character that cant be seen where the LF shows).

If the Line Ends need to be corrected and the file is small enough in size, you can change the line endings in NotePad++ (or paste into word then back into Notepad - although this will make CRLF only).

This may cause some functions that read these files to potenitially no longer function (The example lines given are from GP Prescribing data - England. The file has changed from a CRLF Line end to an LF line end). This stopped an SSIS job from running and failed as couldn't read the LF line endings.

Source of Line Ending Information: https://en.wikipedia.org/wiki/Newline#Representations_in_different_character_encoding_specifications

Hope this helps someone in future :) CRLF = Windows based, LF or CF are from Unix based systems (Linux, MacOS etc.)

Another python3 implementation that involves the use of Abstract classes with super(). You should remember that

super().__init__(name, 10)

has the same effect as

Person.__init__(self, name, 10)

Remember there's a hidden 'self' in super(), So the same object passes on to the superclass init method and the attributes are added to the object that called it. Hence super()gets translated to Person and then if you include the hidden self, you get the above code frag.

from abc import ABCMeta, abstractmethod
class Person(metaclass=ABCMeta):
    name = ""
    age = 0

    def __init__(self, personName, personAge):
        self.name = personName
        self.age = personAge

    @abstractmethod
    def showName(self):
        pass

    @abstractmethod
    def showAge(self):
        pass


class Man(Person):

    def __init__(self, name, height):
        self.height = height
        # Person.__init__(self, name, 10)
        super().__init__(name, 10)  # same as Person.__init__(self, name, 10)
        # basically used to call the superclass init . This is used incase you want to call subclass init
        # and then also call superclass's init.
        # Since there's a hidden self in the super's parameters, when it's is called,
        # the superclasses attributes are a part of the same object that was sent out in the super() method

    def showIdentity(self):
        return self.name, self.age, self.height

    def showName(self):
        pass

    def showAge(self):
        pass


a = Man("piyush", "179")
print(a.showIdentity())

$num = "+918883967576";

$str = substr($num, 3);

echo $str;

Output:8883967576

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

I was getting this error too, although my issue was that I kept switching between two corporate networks via my Virtual Machine, with different access credentials. I had to run the command prompt:

ipconfig /renew

After this my network issues were resolved and I could connect once again to SQL.

Here's a simple and working method I found elsewhere:

string hexString = "7FF";
int hexNumber;
sscanf(hexString.c_str(), "%x", &hexNumber);

Please note that you might prefer using unsigned long integer/long integer, to receive the value. Another note, the c_str() function just converts the std::string to const char* .

So if you have a const char* ready, just go ahead with using that variable name directly, as shown below [I am also showing the usage of the unsigned long variable for a larger hex number. Do not confuse it with the case of having const char* instead of string]:

const char *hexString = "7FFEA5"; //Just to show the conversion of a bigger hex number
unsigned long hexNumber; //In case your hex number is going to be sufficiently big.
sscanf(hexString, "%x", &hexNumber);

This works just perfectly fine (provided you use appropriate data types per your need).

Your best option is through PHP: All version requests from the client side cannot be trusted since your Apache could be configured with ServerTokens Prod and ServerSignature Off. See: http://www.petefreitag.com/item/419.cfm

Here's a simple way to test it:

public class OperatorTest {     
    public static void main(String[] args) {
        boolean a = false;
        a &= b();
    }

    private static boolean b() {
        System.out.println("b() was called");
        return true;
    }
}

The output is b() was called, therefore the right-hand operand is evaluated.

So, as already mentioned by others, a &= b is the same as a = a & b.

This is the syntax you need:

CASE WHEN countries LIKE '%'+@selCountry+'%' THEN 'national' ELSE 'regional' END

Although, as per your original problem, I'd solve it differently, splitting the content of @selcountry int a table form and joining to it.

If there is anyone like me who is experiencing this issue using Vue.js, simply adding .prevent will do the trick: @click.prevent="someAction"

If you want to count the number of records in your table, simply run:

    SELECT COUNT(*) FROM your_table;

Paolo Bergantino's answer has the great advantage of only using the stdlib, and works for this simple example where there are no decorator arguments nor decorated function arguments.

However it has 3 major limitations if you want to tackle more general cases:

• as already noted in several answers, you can not easily modify the code to add optional decorator arguments. For example creating a makestyle(style='bold') decorator is non-trivial.
• besides, wrappers created with @functools.wraps do not preserve the signature, so if bad arguments are provided they will start executing, and might raise a different kind of error than the usual TypeError.
• finally, it is quite difficult in wrappers created with @functools.wraps to access an argument based on its name. Indeed the argument can appear in *args, in **kwargs, or may not appear at all (if it is optional).

I wrote decopatch to solve the first issue, and wrote makefun.wraps to solve the other two. Note that makefun leverages the same trick than the famous decorator lib.

This is how you would create a decorator with arguments, returning truly signature-preserving wrappers:

from decopatch import function_decorator, DECORATED
from makefun import wraps

@function_decorator
def makestyle(st='b', fn=DECORATED):
    open_tag = "<%s>" % st
    close_tag = "</%s>" % st

    @wraps(fn)
    def wrapped(*args, **kwargs):
        return open_tag + fn(*args, **kwargs) + close_tag

    return wrapped

decopatch provides you with two other development styles that hide or show the various python concepts, depending on your preferences. The most compact style is the following:

from decopatch import function_decorator, WRAPPED, F_ARGS, F_KWARGS

@function_decorator
def makestyle(st='b', fn=WRAPPED, f_args=F_ARGS, f_kwargs=F_KWARGS):
    open_tag = "<%s>" % st
    close_tag = "</%s>" % st
    return open_tag + fn(*f_args, **f_kwargs) + close_tag

In both cases you can check that the decorator works as expected:

@makestyle
@makestyle('i')
def hello(who):
    return "hello %s" % who

assert hello('world') == '<b><i>hello world</i></b>'    

Please refer to the documentation for details.

ES6 Arrow functions:

In javascript the => is the symbol of an arrow function expression. A arrow function expression does not have its own this binding and therefore cannot be used as a constructor function. for example:

var words = 'hi from outside object';_x000D_
_x000D_
let obj = {_x000D_
  words: 'hi from inside object',_x000D_
  talk1: () => {console.log(this.words)},_x000D_
  talk2: function () {console.log(this.words)}_x000D_
}_x000D_
_x000D_
obj.talk1();  // doesn't have its own this binding, this === window_x000D_
obj.talk2();  // does have its own this binding, this is obj

Rules of using arrow functions:

• If there is exactly one argument you can omit the parentheses of the argument.
• If you return an expression and do this on the same line you can omit the {} and the return statement

For example:

let times2 = val => val * 2;  _x000D_
// It is on the same line and returns an expression therefore the {} are ommited and the expression returns implictly_x000D_
// there also is only one argument, therefore the parentheses around the argument are omitted_x000D_
_x000D_
console.log(times2(3));

You have to convert the response to JSON using Gson.toJson(object).

For example:

return Response.status(Status.OK).entity(new Gson().toJson(Student)).build();

regarding AlexB's post:

 \'  Apostrophe or single quote
 \"  Double quote

escaping single quotes is only valid in single quoted json strings
escaping double quotes is only valid in double quoted json strings

example:

'Bart\'s car'       -> valid
'Bart says \"Hi\"'  -> invalid

If you're using mod_php, you can use apache_get_modules(). This will return an array of all enabled modules, so to check if mod_rewrite is enabled, you could simply do

in_array('mod_rewrite', apache_get_modules());

Unfortunately, you're most likely trying to do this with CGI, which makes it a little bit more difficult.

You can test it using the following, though

strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false

If the above condition evaluates to true, then mod_write is enabled.

If the 2nd company is happy for you to access their content in an IFrame then they need to take the restriction off - they can do this fairly easily in the IIS config.

There's nothing you can do to circumvent it and anything that does work should get patched quickly in a security hotfix. You can't tell the browser to just render the frame if the source content header says not allowed in frames. That would make it easier for session hijacking.

If the content is GET only you don't post data back then you could get the page server side and proxy the content without the header, but then any post back should get invalidated.

Guava library

We have a Guava class for this: com.google.common.net.MediaType.

It was released with Guava 12 as stated in the source code and in Issue 823. Sources are available, too.

Here is the way I got that:

@Component
public class ApplicationStartup implements ApplicationListener<ApplicationReadyEvent> {

    /**
     * This event is executed as late as conceivably possible to indicate that
     * the application is ready to service requests.
     */

    @Autowired
    private MovieRepositoryImpl movieRepository;

    @Override
    public void onApplicationEvent(final ApplicationReadyEvent event) {
        seedData();
    }

    private void seedData() {
        movieRepository.save(new Movie("Example"));

        // ... add more code
    }

}

If you want to unit test code then you need to isolate your code you want to test (in this case your service) from external resources (e.g. databases). You could probably do this with some sort of in-memory EF provider, however a much more common way is to abstract away your EF implementation e.g. with some sort of repository pattern. Without this isolation any tests you write will be integration tests, not unit tests.

As for testing EF code - I write automated integration tests for my repositories that write various rows to the database during their initialization, and then call my repository implementations to make sure that they behave as expected (e.g. making sure that results are filtered correctly, or that they are sorted in the correct order).

These are integration tests not unit tests, as the tests rely on having a database connection present, and that the target database already has the latest up-to-date schema installed.

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

Swift 3:

let documentsURL = try! FileManager().url(for: .documentDirectory,
                                          in: .userDomainMask,
                                          appropriateFor: nil,
                                          create: true)

... gives you a file URL of the documents directory. The following checks if there's a file named foo.html:

let fooURL = documentsURL.appendingPathComponent("foo.html")
let fileExists = FileManager().fileExists(atPath: fooURL.path)

Objective-C:

NSString* documentsPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)[0];

NSString* foofile = [documentsPath stringByAppendingPathComponent:@"foo.html"];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];

"Unable to load the requested file"

Can be also caused by access permissions under linux , make sure you set the correct read permissions for the directory "views/home"

Be careful when iterating over arrays!!

It is a common misconception that using the index of the element in the array is an acceptable way of suppressing the error you are probably familiar with:

Each child in an array should have a unique "key" prop.

However, in many cases it is not! This is anti-pattern that can in some situations lead to unwanted behavior.

Understanding the key prop

React uses the key prop to understand the component-to-DOM Element relation, which is then used for the reconciliation process. It is therefore very important that the key always remains unique, otherwise there is a good chance React will mix up the elements and mutate the incorrect one. It is also important that these keys remain static throughout all re-renders in order to maintain best performance.

That being said, one does not always need to apply the above, provided it is known that the array is completely static. However, applying best practices is encouraged whenever possible.

A React developer said in this GitHub issue:

• key is not really about performance, it's more about identity (which in turn leads to better performance). randomly assigned and changing values are not identity
• We can't realistically provide keys [automatically] without knowing how your data is modeled. I would suggest maybe using some sort of hashing function if you don't have ids
• We already have internal keys when we use arrays, but they are the index in the array. When you insert a new element, those keys are wrong.

In short, a key should be:

• Unique - A key cannot be identical to that of a sibling component.
• Static - A key should not ever change between renders.

Using the key prop

As per the explanation above, carefully study the following samples and try to implement, when possible, the recommended approach.

Bad (Potentially)

<tbody>
    {rows.map((row, i) => {
        return <ObjectRow key={i} />;

This is arguably the most common mistake seen when iterating over an array in React. This approach isn't technically "wrong", it's just... "dangerous" if you don't know what you are doing. If you are iterating through a static array then this is a perfectly valid approach (e.g. an array of links in your navigation menu). However, if you are adding, removing, reordering or filtering items, then you need to be careful. Take a look at this detailed explanation in the official documentation.

class MyApp extends React.Component {
  constructor() {
    super();
    this.state = {
      arr: ["Item 1"]
    }
  }
  
  click = () => {
    this.setState({
      arr: ['Item ' + (this.state.arr.length+1)].concat(this.state.arr),
    });
  }
  
  render() {
    return(
      <div>
        <button onClick={this.click}>Add</button>
        <ul>
          {this.state.arr.map(
            (item, i) => <Item key={i} text={"Item " + i}>{item + " "}</Item>
          )}
        </ul>
      </div>
    );
  }
}

const Item = (props) => {
  return (
    <li>
      <label>{props.children}</label>
      <input value={props.text} />
    </li>
  );
}

ReactDOM.render(<MyApp />, document.getElementById("app"));

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<div id="app"></div>

In this snippet we are using a non-static array and we are not restricting ourselves to using it as a stack. This is an unsafe approach (you'll see why). Note how as we add items to the beginning of the array (basically unshift), the value for each <input> remains in place. Why? Because the key doesn't uniquely identify each item.

In other words, at first Item 1 has key={0}. When we add the second item, the top item becomes Item 2, followed by Item 1 as the second item. However, now Item 1 has key={1} and not key={0} anymore. Instead, Item 2 now has key={0}!!

As such, React thinks the <input> elements have not changed, because the Item with key 0 is always at the top!

So why is this approach only sometimes bad?

This approach is only risky if the array is somehow filtered, rearranged, or items are added/removed. If it is always static, then it's perfectly safe to use. For example, a navigation menu like ["Home", "Products", "Contact us"] can safely be iterated through with this method because you'll probably never add new links or rearrange them.

In short, here's when you can safely use the index as key:

• The array is static and will never change.
• The array is never filtered (display a subset of the array).
• The array is never reordered.
• The array is used as a stack or LIFO (last in, first out). In other words, adding can only be done at the end of the array (i.e push), and only the last item can ever be removed (i.e pop).

Had we instead, in the snippet above, pushed the added item to the end of the array, the order for each existing item would always be correct.

Very bad

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={Math.random()} />;
    })}
</tbody>

While this approach will probably guarantee uniqueness of the keys, it will always force react to re-render each item in the list, even when this is not required. This a very bad solution as it greatly impacts performance. Not to mention that one cannot exclude the possibility of a key collision in the event that Math.random() produces the same number twice.

Unstable keys (like those produced by Math.random()) will cause many component instances and DOM nodes to be unnecessarily recreated, which can cause performance degradation and lost state in child components.

Very good

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={row.uniqueId} />;
    })}
</tbody>

This is arguably the best approach because it uses a property that is unique for each item in the dataset. For example, if rows contains data fetched from a database, one could use the table's Primary Key (which typically is an auto-incrementing number).

The best way to pick a key is to use a string that uniquely identifies a list item among its siblings. Most often you would use IDs from your data as keys

Good

componentWillMount() {
  let rows = this.props.rows.map(item => { 
    return {uid: SomeLibrary.generateUniqueID(), value: item};
  });
}

...

<tbody>
    {rows.map((row) => {
        return <ObjectRow key={row.uid} />;
    })}
</tbody>

This is also a good approach. If your dataset does not contain any data that guarantees uniqueness (e.g. an array of arbitrary numbers), there is a chance of a key collision. In such cases, it is best to manually generate a unique identifier for each item in the dataset before iterating over it. Preferably when mounting the component or when the dataset is received (e.g. from props or from an async API call), in order to do this only once, and not each time the component re-renders. There are already a handful of libraries out there that can provide you such keys. Here is one example: react-key-index.

this is probably a late answer but i think the most proper way is to use the same piece of code angular use when doing a "get" request using you $httpParamSerializer will have to inject it to your controller so you can simply do the following without having to use Jquery at all , $http.post(url,$httpParamSerializer({param:val}))

app.controller('ctrl',function($scope,$http,$httpParamSerializer){
    $http.post(url,$httpParamSerializer({param:val,secondParam:secondVal}));
}

require section This section contains the packages/dependencies which are better candidates to be installed/required in the production environment.

require-dev section: This section contains the packages/dependencies which can be used by the developer to test her code (or to experiment on her local machine and she doesn't want these packages to be installed on the production environment).

Here is a bare bones version:

Let's say that you have a date in Cell A1 in the format you described. For example: 19760210.

Then this formula will give you the date you want:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2)).

On my system (Excel 2010) it works with strings or floats.

Here's the best answer, and the easiest! Put an extra password field in front of your input field and set the display:none , so that when the browser fills it in, it does it in an input that you don't care about.

Change this:

<input type="password" name="password" size="25" class="input" id="password" value="">

to this:

<input type="password" style="display:none;">
<input type="password" name="password" size="25" class="input" id="password" value="">

Try this:

>>> import time
>>> time.strftime("%Y-%m-%d %H:%M:%S", time.gmtime(1347517119))
'2012-09-12 23:18:39'

Also in MySQL, you can FROM_UNIXTIME like:

INSERT INTO tblname VALUES (FROM_UNIXTIME(1347517119))

For your 2nd question, it is probably because getbbb_class.end_time is a string. You can convert it to numeric like: float(getbbb_class.end_time)

Just download minimum prefered SDK from SDK Manager, then build. Works for me.

You're looking for dir to return the directory contents.

To loop over the results, you can simply do the following:

dirlist = dir('.');
for i = 1:length(dirlist)
    dirlist(i)
end

This should give you output in the following format, e.g.:

name: 'my_file'
date: '01-Jan-2010 12:00:00'
bytes: 56
isdir: 0
datenum: []

yes please download curl-devel as instructed above. also don't forget to link to lib curl:

-L/path/of/curl/lib/libcurl.a (g++)

cheers

I'm assuming you mean that you don't care which row is used to obtain the title, id, and commentname values (you have "rob" for all of the rows, but I don't know if that is actually something that would be enforced or not in your data model). If so, then you can use windowing functions to return the first row for a given email address:

select
    id,
    title,
    email,
    commentname

from
(
select 
    *, 
    row_number() over (partition by email order by id) as RowNbr 

from YourTable
) source

where RowNbr = 1

It works for 5.7.8:

mysql> create table t1(updated datetime NOT NULL DEFAULT '0000-00-00 00:00:00');
Query OK, 0 rows affected (0.01 sec)

mysql> show create table t1;

If it works for MySQL 5.6 and 5.7.8, but fails on 5.7.11. Then it probably is a regression bug for 5.7.11.

Yes in SQl <> is the same as != which is not equal.....excepts for NULLS of course, in that case you need to use IS NULL or IS NOT NULL

The code you wrote will always return true because state cannot be both 10 and 15 for the statement to be false. if ((state != 10) && (state != 15).... AND is what you need not OR.

Use $.inArray instead. This returns the index of the element in the array.

JSFIDDLE DEMO

var statesArray = [10, 15, 19]; // list out all

var index = $.inArray(state, statesArray);

if(index == -1) {
    console.log("Not there in array");
    return true;

} else {
    console.log("Found it");
    return false;
}

Try this one

$('<div></div>').appendTo('body')
  .html('<div><h6>Yes or No?</h6></div>')
  .dialog({
      modal: true, title: 'message', zIndex: 10000, autoOpen: true,
      width: 'auto', resizable: false,
      buttons: {
          Yes: function () {
              doFunctionForYes();
              $(this).dialog("close");
          },
          No: function () {
              doFunctionForNo();
              $(this).dialog("close");
          }
      },
      close: function (event, ui) {
          $(this).remove();
      }
});

Fiddle

This is Working for me

$().popover({container: 'body'})

This example will exit after 5 seconds if another instance is already running.

// unique id for global mutex - Global prefix means it is global to the machine
const string mutex_id = "Global\\{B1E7934A-F688-417f-8FCB-65C3985E9E27}";

static void Main(string[] args)
{

    using (var mutex = new Mutex(false, mutex_id))
    {
        try
        {
            try
            {
                if (!mutex.WaitOne(TimeSpan.FromSeconds(5), false))
                {
                    Console.WriteLine("Another instance of this program is running");
                    Environment.Exit(0);
                }
            }
            catch (AbandonedMutexException)
            {
                // Log the fact the mutex was abandoned in another process, it will still get aquired
            }

            // Perform your work here.
        }
        finally
        {

1. first you can do with this style:

   mda="/usr/mda"
   if [ ! -L "${mda}" ]; then
     echo "=> File doesn't exist"
   fi
   

2. if you want to do it in more advanced style you can write it like below:

   #!/bin/bash
   mda="$1"
   if [ -e "$1" ]; then
       if [ ! -L "$1" ]
       then
           echo "you entry is not symlink"
       else
           echo "your entry is symlink"
       fi
   else
     echo "=> File doesn't exist"
   fi
   

the result of above is like:

root@linux:~# ./sym.sh /etc/passwd
you entry is not symlink
root@linux:~# ./sym.sh /usr/mda 
your entry is symlink
root@linux:~# ./sym.sh 
=> File doesn't exist

| is a metacharacter in regex. You'd need to escape it:

String[] value_split = rat_values.split("\\|");

You can find the symlinks by looking for files that have a mode of 120000, possibly with this command:

git ls-files -s | awk '/120000/{print $4}'

Once you replace the links, I would recommend marking them as unchanged with git update-index --assume-unchanged, rather than listing them in .git/info/exclude.

Keep in mind the second parameter to @Html.HiddenFor will only be used to set the value when it can't find route or model data matching the field. Darin is correct, use view model.

What the OP wants to do, is delete additional properties in his Google analytics. Properties that are not his but belong to someone else.

Apparently, the only way to do this, is to contact the owner of that website who is the administrator, and asked them to remove you.

Or you can just create a new Google account, and add your properties to the new account.

None of these are real good solutions. Thank you Google for caring so much about SEO people.

To add insult to injury, if you go over 25 accounts, you must contact Google to get permission to add another.

Lesson learned: Do not add other peoples websites to your Google analytics account. Create a separate account so that if you have to start over, you don't lose any data from your websites. It's also good to have more than one Google analytics account.

run

gradle clean 

then try

gradle build 

it worked for me

Try this:

update table YourTable
set YourField = substring(YourField, 5, len(YourField)-3);

Instead of a List<UserRole>, you can let your Model contain a SelectList<UserRole>. Also add a property SelectedUserRoleId to store... well... the selected UserRole's Id value.

Fill up the SelectList, then in your View use:

@Html.DropDownListFor(x => x.SelectedUserRoleId, x.UserRole)

and you should be fine.

The most important difference will be the clarity of your code. Yes, yes, what's been said above is true, but [[ ]] brings your code in line with what you would expect in high level languages, especially in regards to AND (&&), OR (||), and NOT (!) operators. Thus, when you move between systems and languages you will be able to interpret script faster which makes your life easier. Get the nitty gritty from a good UNIX/Linux reference. You may find some of the nitty gritty to be useful in certain circumstances, but you will always appreciate clear code! Which script fragment would you rather read? Even out of context, the first choice is easier to read and understand.

if [[ -d $newDir && -n $(echo $newDir | grep "^${webRootParent}") && -n $(echo $newDir | grep '/$') ]]; then ...

or

if [ -d "$newDir" -a -n "$(echo "$newDir" | grep "^${webRootParent}")" -a -n "$(echo "$newDir" | grep '/$')" ]; then ...

Font myFont = new Font ("Courier New", 1, 17);

The 17 represents the font size. Once you have that, you can put:

g.setFont (myFont);
g.drawString ("Hello World", 10, 10);

Remove the FormsModule from Declaration:[] and Add the FormsModule in imports:[]

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})

ddList.Items.FindByText("oldValue").Selected = false;
ddList.Items.FindByText("newValue").Selected = true;

Alternatively, you can use jinfo

jinfo -flags <vmid> 
jinfo -sysprops <vmid>

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator

And another link here

AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).

Run Power-shell as administrator.

then run this command

Set-ExecutionPolicy Unrestricted

Use with CAUTION

Easier if the input is a string, we can use split()

decimal = input("Input decimal number: ") #123.456

# split 123.456 by dot = ['123', '456']
after_coma = decimal.split('.')[1] 

# because only index 1 is taken then '456'
print(after_coma) # '456'

if you want to make a number type print(int(after_coma)) # 456

To read the result you can read it like a simple php array.

For example, getting the name can be done like $user['name'], and so on. The method fetch(PDO::FETCH_ASSOC) will only return 1 tuple tho. If you want to get all tuples, you can use fetchall(PDO::FETCH_ASSOC). You can go through the multidimensional array and get the values just the same.

As per Angular2 final, you do not even have to import FORM_DIRECTIVES as suggested above by many. However, the syntax has been changed as kebab-case was dropped for the betterment.

Just replace ng-model with ngModel and wrap it in a box of bananas. But you have spilt the code into two files now:

app.ts:

import { Component } from '@angular/core';

@Component({
  selector: 'ng-app',
  template: `
    <input id="name" type="text" [(ngModel)]="name"  />
    {{ name }}
  `
})
export class DataBindingComponent {
  name: string;

  constructor() {
    this.name = 'Jose';
  }
}

app.module.ts:

import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { DataBindingComponent } from './app'; //app.ts above

@NgModule({
  declarations: [DataBindingComponent],
  imports:      [BrowserModule, FormsModule],
  bootstrap:    [DataBindingComponent]
})
export default class MyAppModule {}

platformBrowserDynamic().bootstrapModule(MyAppModule);

The two alternative you gave are semantically identical, but using make([]int, 0) will result in an internal call to runtime.makeslice (Go 1.14).

You also have the option to leave it with a nil value:

var myslice []int

As written in the Golang.org blog:

a nil slice is functionally equivalent to a zero-length slice, even though it points to nothing. It has length zero and can be appended to, with allocation.

A nil slice will however json.Marshal() into "null" whereas an empty slice will marshal into "[]", as pointed out by @farwayer.

None of the above options will cause any allocation, as pointed out by @ArmanOrdookhani.

    import os
    os.mkdir('directory name') #### this command for creating directory

NSArray* foo = [@"10/04/2011" componentsSeparatedByString: @"/"];
NSString* firstBit = [foo objectAtIndex: 0];

Update 7/3/2018:

Now that the question has acquired a Swift tag, I should add the Swift way of doing this. It's pretty much as simple:

let substrings = "10/04/2011".split(separator: "/")
let firstBit = substrings[0]

Although note that it gives you an array of Substring. If you need to convert these back to ordinary strings, use map

let strings = "10/04/2011".split(separator: "/").map{ String($0) }
let firstBit = strings[0]

or

let firstBit = String(substrings[0])

Like many before pointed out you shall add

compile files('libs/gson-2.2.3.jar') 

to your build.gradle file.

However I have a project in Android Studio that was migrated from Eclipse and in this case the "libs" folder is named "lib" so for me removing the "s" solved the problem.

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];

    $(document).ready(function($) {
    var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
    $(".color_cell").each(function() {
        code = $(this).attr('id');
        ids.push(code);
        $div.append(code + "<br />");
    });



});

Your format string is wrong. Change it to

insert = DateTime.ParseExact(line[i], "M/d/yyyy hh:mm", CultureInfo.InvariantCulture);

As mentioned above, BOOL is a signed char. bool - type from C99 standard (int).

BOOL - YES/NO. bool - true/false.

See examples:

bool b1 = 2;
if (b1) printf("REAL b1 \n");
if (b1 != true) printf("NOT REAL b1 \n");

BOOL b2 = 2;
if (b2) printf("REAL b2 \n");
if (b2 != YES) printf("NOT REAL b2 \n");

And result is

REAL b1
REAL b2
NOT REAL b2

Note that bool != BOOL. Result below is only ONCE AGAIN - REAL b2

b2 = b1;
if (b2) printf("ONCE AGAIN - REAL b2 \n");
if (b2 != true) printf("ONCE AGAIN - NOT REAL b2 \n");

If you want to convert bool to BOOL you should use next code

BOOL b22 = b1 ? YES : NO; //and back - bool b11 = b2 ? true : false;

So, in our case:

BOOL b22 = b1 ? 2 : NO;
if (b22)    printf("ONCE AGAIN MORE - REAL b22 \n");
if (b22 != YES) printf("ONCE AGAIN MORE- NOT REAL b22 \n");

And so.. what we get now? :-)

String [] obj = (from c in db.Contacts
                           where c.FirstName.StartsWith(prefixText)
                           select c.FirstName).ToArray();
            return obj;

StartsWith() and EndsWith() can help you a lot here. If you want to find data in between the field, then Contains() can be used.

I think you want SELECT * FROM INFORMATION_SCHEMA.TABLES

See http://dev.mysql.com/doc/refman/5.0/en/tables-table.html

You don't need a counter for back presses.

Just store a reference to the toast that is shown:

private Toast backtoast;

Then,

public void onBackPressed() {
    if(USER_IS_GOING_TO_EXIT) {
        if(backtoast!=null&&backtoast.getView().getWindowToken()!=null) {
            finish();
        } else {
            backtoast = Toast.makeText(this, "Press back to exit", Toast.LENGTH_SHORT);
            backtoast.show();
        }
    } else {
        //other stuff...
        super.onBackPressed();
    }
}

This will call finish() if you press back while the toast is still visible, and only if the back press would result in exiting the application.

This is a very round-about way of doing it but if you want to make a histogram where you already know the bin values but dont have the source data, you can use the np.random.randint function to generate the correct number of values within the range of each bin for the hist function to graph, for example:

import numpy as np
import matplotlib.pyplot as plt

data = [np.random.randint(0, 9, *desired y value*), np.random.randint(10, 19, *desired y value*), etc..]
plt.hist(data, histtype='stepfilled', bins=[0, 10, etc..])

as for labels you can align x ticks with bins to get something like this:

#The following will align labels to the center of each bar with bin intervals of 10
plt.xticks([5, 15, etc.. ], ['Label 1', 'Label 2', etc.. ])

From the fine manual.

You must own the table to use ALTER TABLE.

Well, despite the fact that you asked that we not "simply" link to other resources, it's pretty foolish when there already exists a community grown (and growing) resource that's really quite good: the Git Community Book. Seriously, this 20+ questions in a question is going to be anything but concise and consistent. The Git Community Book is available as both HTML and PDF and answers many of your questions with clear, well formatted and peer reviewed answers and in a format that allows you to jump straight to your problem at hand.

Alas, if my post really upsets you then I'll delete it. Just say so.

Or just use old-school DOM methods when JQ has a monkey in the middle somewhere.

var myElement = $('#my_element')[0];
var myElClass = myElement.getAttribute('class').split(/\s+/g);
//splits class into an array based on 1+ white space characters

myElClass.push('new_class');

myElement.setAttribute('class', myElClass.join(' '));

//$(myElement) to return to JQ wrapper-land

Learn the DOM people. Even in 2016's framework-palooza it helps quite regularly. Also, if you ever hear someone compare the DOM to assembly, kick them for me.

PHP runs on the server and Javascript runs on the client, so you can't set a PHP variable to equal a Javascript variable without sending the value to the server. You can, however, set a Javascript variable to equal a PHP variable:

<script type="text/javascript">
  var foo = '<?php echo $foo ?>';
</script>

To send a Javascript value to PHP you'd need to use AJAX. With jQuery, it would look something like this (most basic example possible):

var variableToSend = 'foo';
$.post('file.php', {variable: variableToSend});

On your server, you would need to receive the variable sent in the post:

$variable = $_POST['variable'];

You can use this QString constructor for conversion from QByteArray to QString:

QString(const QByteArray &ba)

QByteArray data;
QString DataAsString = QString(data);

Make sure you have the Visual C++ Redistributable package installed on your machine.

The copy command is a SQL*Plus command (not a SQL Developer command). If you have your tnsname entries setup for SID1 and SID2 (e.g. try a tnsping), you should be able to execute your command.

Another assumption is that table1 has the same columns as the message_table (and the columns have only the following data types: CHAR, DATE, LONG, NUMBER or VARCHAR2). Also, with an insert command, you would need to be concerned about primary keys (e.g. that you are not inserting duplicate records).

I tried a variation of your command as follows in SQL*Plus (with no errors):

copy from scott/tiger@db1 to scott/tiger@db2 create new_emp using select * from emp;

After I executed the above statement, I also truncate the new_emp table and executed this command:

copy from scott/tiger@db1 to scott/tiger@db2 insert new_emp using select * from emp;

With SQL Developer, you could do the following to perform a similar approach to copying objects:

1. On the tool bar, select Tools>Database copy.

2. Identify source and destination connections with the copy options you would like.

3. For object type, select table(s).

4. Specify the specific table(s) (e.g. table1).

The copy command approach is old and its features are not being updated with the release of new data types. There are a number of more current approaches to this like Oracle's data pump (even for tables).

If using webdriverJs (node.js),

driver.findElement(webdriver.By.name('btnCalculate')).click().then(function() {
    driver.sleep(5000);
});

The code above makes browser wait for 5 seconds after clicking the button.

df = data.frame(matrix("", ncol = 3, nrow = 10)  

This is a direct conversion from your PHP code:

//Loading the variable
var mystr = '0000000020C90037:TEMP:data';

//Splitting it with : as the separator
var myarr = mystr.split(":");

//Then read the values from the array where 0 is the first
//Since we skipped the first element in the array, we start at 1
var myvar = myarr[1] + ":" + myarr[2];

// Show the resulting value
console.log(myvar);
// 'TEMP:data'

Yes it is correct. you can do it with an inner class.

This is not an answer to your original question: "Appending output of a Batch file To log file?"

For reference, it's an answer to your followup question: "What lines should i add to my batch file which will make it execute after every 30mins?"

(But I would take Jon Skeet's advice: "You probably shouldn't do that in your batch file - instead, use Task Scheduler.")

Timeout:

• timeout command 1
• timeout command 2

Example (1 second):

TIMEOUT /T 1000 /NOBREAK

Sleep:

• sleep command (if sleep.exe is installed)

Example (1 second):

sleep -m 1000

Alternative methods:

• Sleeping in a batch file
• batch script, put to sleep until certain time

Here's an answer to your 2nd followup question: "Along with the Timestamp?"

Create a date and time stamp in your batch files

Example:

echo *** Date: %DATE:/=-% and Time:%TIME::=-% *** >> output.log

Are you trying to view an array with memory allocated dynamically? If not, you can view an array for C++ and C# by putting it in the watch window in the debugger, with its contents visible when you expand the array on the little (+) in the watch window by a left mouse-click.

If it's a pointer to a dynamically allocated array, to view N contents of the pointer, type "pointer, N" in the watch window of the debugger. Note, N must be an integer or the debugger will give you an error saying it can't access the contents. Then, left click on the little (+) icon that appears to view the contents.

I am reading the Pro ASP.NET MVC 4 book as well, and ran into the same problem you were having. For me, I started having the problem after making the changes prescribed in the 'Adding Model Validation' section of the book. The way I resolved the problem is by moving my database from the localdb to the full-blown SQL Server 2012 server. (BTW, I know that I am lucky I could switch to the full-blown version, so don't hate me. ;-))) There must be something with the communication to the db that is causing the problem.

This works the best, in my case, I tried it all

.div_class {
    clear: left;
}

setting the overflow should take care of it, but you need to set the height of Content also. If the height attribute is not set, the div will grow vertically as tall as it needs to, and scrollbars wont be needed.

See Example: http://jsfiddle.net/ftkbL/1/

Unfortunately, MySQL doesn't support DEFAULT parameter values, so:

CREATE PROCEDURE `blah`
(
  myDefaultParam int DEFAULT 0
)
BEGIN
  -- Do something here
END

returns the error:

ERROR 1064 (42000): You have an error in your SQL syntax; check the manual
that corresponds to your MySQL server version for the right syntax to use 
near 'DEFAULT 0) BEGIN END' at line 3

To work around this limitation, simply create additional procedures that assign default values to the original procedure:

DELIMITER //

DROP PROCEDURE IF EXISTS blah//
DROP PROCEDURE IF EXISTS blah2//
DROP PROCEDURE IF EXISTS blah1//
DROP PROCEDURE IF EXISTS blah0//

CREATE PROCEDURE blah(param1 INT UNSIGNED, param2 INT UNSIGNED)
BEGIN
    SELECT param1, param2;
END;
//

CREATE PROCEDURE blah2(param1 INT UNSIGNED, param2 INT UNSIGNED)
BEGIN
    CALL blah(param1, param2);
END;
//

CREATE PROCEDURE blah1(param1 INT UNSIGNED)
BEGIN
    CALL blah2(param1, 3);
END;
//

CREATE PROCEDURE blah0()
BEGIN
    CALL blah1(4);
END;
//

Then, running this:

CALL blah(1, 1);
CALL blah2(2, 2);
CALL blah1(3);
CALL blah0();

will return:

+--------+--------+
| param1 | param2 |
+--------+--------+
|      1 |      1 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

+--------+--------+
| param1 | param2 |
+--------+--------+
|      2 |      2 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

+--------+--------+
| param1 | param2 |
+--------+--------+
|      3 |      3 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

+--------+--------+
| param1 | param2 |
+--------+--------+
|      4 |      3 |
+--------+--------+
1 row in set (0.00 sec)

Query OK, 0 rows affected (0.00 sec)

Then, if you make sure to only use the blah2(), blah1() and blah0() procedures, your code will not need to be immediately updated, when you add a third parameter to the blah() procedure.

I am also new to MVC and I received the same error and found that it is not passing proper routeValues in the Index view or whatever view is present to view the all data.

It was as below

<td>
            @Html.ActionLink("Edit", "Edit", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>

I changed it to the as show below and started to work properly.

<td>
            @Html.ActionLink("Edit", "Edit", new { EmployeeID=item.EmployeeID }) |
            @Html.ActionLink("Details", "Details", new { /* id=item.PrimaryKey */ }) |
            @Html.ActionLink("Delete", "Delete", new { /* id=item.PrimaryKey */ })
        </td>

Basically this error can also come because of improper navigation also.

Just wrote a class to compute smallest (not to be taken literally) number of edits to transform one string into another string:

http://www.raymondhill.net/finediff/

It has a static function to render a HTML version of the diff.

It's a first version, and likely to be improved, but it works just fine as of now, so I am throwing it out there in case someone needs to generate a compact diff efficiently, like I needed.

Edit: It's on Github now: https://github.com/gorhill/PHP-FineDiff

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

It also works without jQuery if you do the following changes:

1. Add type="button" to the edit button in order not to trigger submission of the form.

2. Change the name of your function from change() to anything else.

3. Don't use hidden="hidden", use CSS instead: style="display: none;".

The following code works for me:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<link rel="STYLESHEET" type="text/css" href="dba_style/buttons.css" />
<title>Untitled Document</title>
</head>
<script type="text/javascript">
function do_change(){
document.getElementById("save").style.display = "block";
document.getElementById("change").style.display = "block";
document.getElementById("cancel").style.display = "block";
}
</script>
<body>
<form name="form1" method="post" action="">
<div class="buttons">

<button type="button" class="regular" name="edit" id="edit" onclick="do_change(); return false;">
    <img src="dba_images/textfield_key.png" alt=""/>
    Edit
</button>

<button type="submit" class="positive" name="save" id="save" style="display:none;">
    <img src="dba_images/apply2.png" alt=""/>
    Save
</button>

<button class="regular" name="change" id="change" style="display:none;">
    <img src="dba_images/textfield_key.png" alt=""/>
    change
</button>

    <button class="negative" name="cancel" id="cancel" style="display:none;">
        <img src="dba_images/cross.png" alt=""/>
        Cancel
    </button>
</div>
</form>
</body>
</html>

This worked for me:

start /d IEXPLORE.EXE www.google.com
start /d IEXPLORE.EXE www.yahoo.com

But for some reason opened them up in Firefox instead?!?

I tried this but it merely opened up sites in two different windows:

start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.google.com
start /d "C:\Program Files\Internet Explorer" IEXPLORE.EXE www.yahoo.com

Just pass the list to np.array:

a = np.array(a)

You can also take this opportunity to set the dtype if the default is not what you desire.

a = np.array(a, dtype=...)

strstr(request, "favicon") != NULL

You also encounter this if you run an Application on a Scheduled Task in Non-Interactive mode.

As soon as you show a Dialog it throws the error:

Showing a modal dialog box or form when the application is not running in UserInteractive mode is not a valid operation. Specify the ServiceNotification or DefaultDesktopOnly style to display a notification from a service application.

You can see its a MessageBox causing the problem in the stack trace:

at System.Windows.Forms.MessageBox.ShowCore(IWin32Window owner, String text, String caption, MessageBoxButtons buttons, MessageBoxIcon icon,  MessageBoxDefaultButton defaultButton, MessageBoxOptions options, Boolean showHelp)  

Solution

If you're running your app on a Scheduled Task send an email instead of showing a Dialog.

You can use the relationLoaded method on the model object. This saved my bacon so hopefully it helps someone else. I was given this suggestion when I asked the same question on Laracasts.

With lodash, you can create new object like this _.set:

obj = _.set({}, key, val);

Or you can set to existing object like this:

var existingObj = { a: 1 };
_.set(existingObj, 'a', 5); // existingObj will be: { a: 5 }

You should take care if you want to use dot (".") in your path, because lodash can set hierarchy, for example:

_.set({}, "a.b.c", "d"); // { "a": { "b": { "c": "d" } } }

You can create an array with all elements from a given Swift Set simply with

let array = Array(someSet)

This works because Set conforms to the SequenceType protocol and an Array can be initialized with a sequence. Example:

let mySet = Set(["a", "b", "a"])  // Set<String>
let myArray = Array(mySet)        // Array<String>
print(myArray) // [b, a]

Apart from tuples being immutable there is also a semantic distinction that should guide their usage. Tuples are heterogeneous data structures (i.e., their entries have different meanings), while lists are homogeneous sequences. Tuples have structure, lists have order.

Using this distinction makes code more explicit and understandable.

One example would be pairs of page and line number to reference locations in a book, e.g.:

my_location = (42, 11)  # page number, line number

You can then use this as a key in a dictionary to store notes on locations. A list on the other hand could be used to store multiple locations. Naturally one might want to add or remove locations from the list, so it makes sense that lists are mutable. On the other hand it doesn't make sense to add or remove items from an existing location - hence tuples are immutable.

There might be situations where you want to change items within an existing location tuple, for example when iterating through the lines of a page. But tuple immutability forces you to create a new location tuple for each new value. This seems inconvenient on the face of it, but using immutable data like this is a cornerstone of value types and functional programming techniques, which can have substantial advantages.

There are some interesting articles on this issue, e.g. "Python Tuples are Not Just Constant Lists" or "Understanding tuples vs. lists in Python". The official Python documentation also mentions this

"Tuples are immutable, and usually contain an heterogeneous sequence ...".

In a statically typed language like Haskell the values in a tuple generally have different types and the length of the tuple must be fixed. In a list the values all have the same type and the length is not fixed. So the difference is very obvious.

Finally there is the namedtuple in Python, which makes sense because a tuple is already supposed to have structure. This underlines the idea that tuples are a light-weight alternative to classes and instances.

SQL Server

To list all the user defined tables of a database:

use [databasename]
select name from sysobjects where type = 'u'

To list all the columns of a table:

use [databasename]
select name from syscolumns where id=object_id('tablename')

You have to mark the single letter as optional too:

([A-Z]{1})? +.*? +

or make the whole part optional

(([A-Z]{1}) +.*? +)?

here is a ruby implementation:

It will catalog by attribute name or the result of a method call.

CatalogGenerator = ->(depth) do
  if depth != 0
    ->(hash, key) do
      hash[key] = Hash.new(&CatalogGenerator[depth - 1])
    end
  else
    ->(hash, key) do
      hash[key] = []
    end
  end
end

def catalog(collection, root_name: :root, by:)
  method_names = [*by]
  log = Hash.new(&CatalogGenerator[method_names.length])
  tree = collection.each_with_object(log) do |item, catalog|
    path = method_names.map { |method_name| item.public_send(method_name)}.unshift(root_name.to_sym)
  catalog.dig(*path) << item
  end
  tree.with_indifferent_access
end

There's a nice article which may answer your question /only it prints the paths instead of collecting them/. Please note that you can experiment with the C++/Python samples in the online IDE.

You can't use AJAX to fetch files from the user machine. This is absolutely the wrong way to go about it.

Use the FileReader API:

<input type="file" id="file input">

js:

console.log(document.getElementById("file input").files); // list of File objects

var file = document.getElementById("file input").files[0];
var reader = new FileReader();
content = reader.readAsText(file);
console.log(content);

Then parse content as CSV. Keep in mind that your parser currently does not deal with escaped values in CSV like: value1,value2,"value 3","value ""4"""

since your ant file's name is build.xml, you should just type ant without ant build.xml. that is: > ant [enter]

It depends on the type of the arguments...

For integer arguments, the single ampersand ("&")is the "bit-wise AND" operator. The double ampersand ("&&") is not defined for anything but two boolean arguments.

For boolean arguments, the single ampersand constitutes the (unconditional) "logical AND" operator while the double ampersand ("&&") is the "conditional logical AND" operator. That is to say that the single ampersand always evaluates both arguments whereas the double ampersand will only evaluate the second argument if the first argument is true.

For all other argument types and combinations, a compile-time error should occur.

Note: Your question is about escaping, not encoding. Escaping is using <, etc. to allow the parser to distinguish between "this is an XML command" and "this is some text". Encoding is the stuff you specify in the XML header (UTF-8, ISO-8859-1, etc).

First of all, like everyone else said, use an XML library. XML looks simple but the encoding+escaping stuff is dark voodoo (which you'll notice as soon as you encounter umlauts and Japanese and other weird stuff like "full width digits" (&#FF11; is 1)). Keeping XML human readable is a Sisyphus' task.

I suggest never to try to be clever about text encoding and escaping in XML. But don't let that stop you from trying; just remember when it bites you (and it will).

That said, if you use only UTF-8, to make things more readable you can consider this strategy:

• If the text does contain '<', '>' or '&', wrap it in <![CDATA[ ... ]]>
• If the text doesn't contain these three characters, don't warp it.

I'm using this in an SQL editor and it allows the developers to cut&paste SQL from a third party SQL tool into the XML without worrying about escaping. This works because the SQL can't contain umlauts in our case, so I'm safe.

for play 2.5.x

Step 1: Stop the netty server (if it is running) using control + D

Step 2: go to sbt-dist/conf

Step 3: edit this file 'sbtConfig.txt' with this

-Dhttp.port=9005

Step 4: Start the server

Step 5: http://host:9005/

Just run the below two lines when you want to exit from the application

android.os.Process.killProcess(android.os.Process.myPid());
System.exit(1);

You can use typeof(N) to get the actual object type, but what you want to do is check the tag, not the type of the DOM element.

In that case, use the elem.tagName or elem.nodeName property.

if you want to get really creative, you can use a dictionary of tagnames and anonymous closures instead if a switch or if/else.

This is the suggested Matplotlib 3 solution from the official website HERE:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x)

ax = plt.subplot(111)
ax.plot(x, y)

# Hide the right and top spines
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

# Only show ticks on the left and bottom spines
ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('bottom')

plt.show()

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

This has been mentioned in earlier comments but I would like to clarify that there are multiple ways to access the auth routes in your web.php file in Laravel ^5.7. depending on your version it might look a little different but they achieve the same result.

First option

Route::auth([
  'register' => false, // Registration Routes...
  'reset' => false, // Password Reset Routes...
  'verify' => false, // Email Verification Routes...
]);

Second option

Auth::routes([
  'register' => false, // Registration Routes...
  'reset' => false, // Password Reset Routes...
  'verify' => false, // Email Verification Routes...
]);

CPython (the classic and prevalent implementation of Python) can't have more than one thread executing Python bytecode at the same time. This means compute-bound programs will only use one core. I/O operations and computing happening inside C extensions (such as numpy) can operate simultaneously.

Other implementation of Python (such as Jython or PyPy) may behave differently, I'm less clear on their details.

The usual recommendation is to use many processes rather than many threads.

my sample code

wv = (WebView) findViewById(R.id.mywebview);
wv.getLayoutParams().height = LayoutParams.MATCH_PARENT; // LayoutParams: android.view.ViewGroup.LayoutParams
// wv.getLayoutParams().height = LayoutParams.WRAP_CONTENT;
wv.requestLayout();//It is necesary to refresh the screen

    PrintWriter out = null; // for writting in file    
    String newLine = System.getProperty("line.separator"); // taking new line 
    out.print("1st Line"+newLine); // print with new line
    out.print("2n Line"+newLine);  // print with new line
    out.close();

That's a good problem. In order to solve that problem you will also have to disable ASLR otherwise the address of g() will be unpredictable.

Disable ASLR:

sudo bash -c 'echo 0 > /proc/sys/kernel/randomize_va_space'

Disable canaries:

gcc overflow.c -o overflow -fno-stack-protector

After canaries and ASLR are disabled it should be a straight forward attack like the ones described in Smashing the Stack for Fun and Profit

Here is a list of security features used in ubuntu: https://wiki.ubuntu.com/Security/Features You don't have to worry about NX bits, the address of g() will always be in a executable region of memory because it is within the TEXT memory segment. NX bits only come into play if you are trying to execute shellcode on the stack or heap, which is not required for this assignment.

Now go and clobber that EIP!

1. another odd testing function

Ok, the assignment was handed in 8+ years ago, but here is another solution based on bit shifting operations:

def isodd(i):
    return(bool(i>>0&1))

testing gives:

>>> isodd(2)
False
>>> isodd(3)
True
>>> isodd(4)
False

2. Nearest Odd number alternative approach

However, instead of a code that says "give me this precise input (an integer odd number) or otherwise I won't do anything" I also like robust codes that say, "give me a number, any number, and I'll give you the nearest pyramid to that number".

In that case this function is helpful, and gives you the nearest odd (e.g. any number f such that 6<=f<8 is set to 7 and so on.)

def nearodd(f):
    return int(f/2)*2+1

Example output:

nearodd(4.9)
5

nearodd(7.2)
7

nearodd(8)
9  

Just downloaded the latest mysqlworkbench which is compatible with the latest encryption:

Note: On Mac big Sur, the latest two versions: 8.0.22 and 8.0.23 are buggy and do not work.

Use 8.0.21 until these are fixed

In addition to @canvastag, use a while loop with shift I think is more concise:

var canvas = document.getElementById('canvas');
var ctx = canvas.getContext('2d');

var poly = [5, 5, 100, 50, 50, 100, 10, 90];

// copy array
var shape = poly.slice(0);

ctx.fillStyle = '#f00'
ctx.beginPath();
ctx.moveTo(shape.shift(), shape.shift());
while(shape.length) {
  ctx.lineTo(shape.shift(), shape.shift());
}
ctx.closePath();
ctx.fill();

d = {0: 'zero', '0': 'ZERO', 1: 'one', '1': 'ONE'}

print("List of enumerated d= ", list(enumerate(d.items())))

output:

List of enumerated d=  [(0, (0, 'zero')), (1, ('0', 'ZERO')), (2, (1, 'one')), (3, ('1', 'ONE'))]

It is not possible to return an array from a C++ function. 8.3.5[dcl.fct]/6:

Functions shall not have a return type of type array or function[...]

Most commonly chosen alternatives are to return a value of class type where that class contains an array, e.g.

struct ArrayHolder
{
    int array[10];
};

ArrayHolder test();

Or to return a pointer to the first element of a statically or dynamically allocated array, the documentation must indicate to the user whether he needs to (and if so how he should) deallocate the array that the returned pointer points to.

E.g.

int* test2()
{
    return new int[10];
}

int* test3()
{
    static int array[10];
    return array;
}

While it is possible to return a reference or a pointer to an array, it's exceedingly rare as it is a more complex syntax with no practical advantage over any of the above methods.

int (&test4())[10]
{
        static int array[10];
        return array;
}

int (*test5())[10]
{
        static int array[10];
        return &array;
}

Not sure if there is an easier way in 2008 version.

I was facing this error while running Karma Unit Test cases Adding MatSelectModule in the imports fixes the issue

imports: [
        HttpClientTestingModule,
        FormsModule,
        MatTableModule,
        MatSelectModule,
        NoopAnimationsModule
      ],

The first argument to a shell script is available as the variable $1, so the simplest implementation would be

if [ "$1" == "-h" ]; then
  echo "Usage: `basename $0` [somestuff]"
  exit 0
fi

But what anubhava said.

An easy solution is use the property zoom:

input[type="checkbox"] {_x000D_
    zoom: 1.5;_x000D_
}

<input type="checkbox" />

tl;dr

Month.FEBRUARY.getValue()  // February ? 2.

2

Details

The Answer by Jon Skeet is correct.

Now we have a modern replacement for those troublesome old legacy date-time classes: the java.time classes.

java.time.Month

Among those classes is the Month enum. An enum carries one or more predefined objects, objects that are automatically instantiated when the class loads. On Month we have a dozen such objects, each given a name: JANUARY, FEBRUARY, MARCH, and so on. Each of those is a static final public class constant. You can use and pass these objects anywhere in your code. Example: someMethod( Month.AUGUST )

Fortunately, they have sane numbering, 1-12 where 1 is January and 12 is December.

Get a Month object for a particular month number (1-12).

Month month = Month.of( 2 );  // 2 ? February.

Going the other direction, ask a Month object for its month number.

int monthNumber = Month.FEBRUARY.getValue();  // February ? 2.

Many other handy methods on this class, such as knowing the number of days in each month. The class can even generate a localized name of the month.

You can get the localized name of the month, in various lengths or abbreviations.

String output = 
    Month.FEBRUARY.getDisplayName( 
        TextStyle.FULL , 
        Locale.CANADA_FRENCH 
    );

février

Also, you should pass objects of this enum around your code base rather than mere integer numbers. Doing so provides type-safety, ensures a valid range of values, and makes your code more self-documenting. See Oracle Tutorial if unfamiliar with the surprisingly powerful enum facility in Java.

You also may find useful the Year and YearMonth classes.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to java.time.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You can use FontAwesome "content" values and apply as follow by css. These apply "chevron right/left" icons.

.custom-slick .slick-prev:before {
    content: "?";
    font-family: 'FontAwesome';
    font-size: 22px;
}
.custom-slick .slick-next:before {
    content: "?";
    font-family: 'FontAwesome';
    font-size: 22px;
}

mine was DispatchQueue.main.sync inside the closer I made it DispatchQueue.main.async and it worked.

You work like with a standard block, that is a square

.circle {
    width: 10em; height: 10em; 
    -webkit-border-radius: 5em; -moz-border-radius: 5em;
  }

This is feature of CSS 3 and it is not very well suporrted, you can count on firefox and safari for sure.

<div class="circle"><span>1234</span></div>

I hope this would be helpful:

.top_image img{
display: block;
margin: 0 auto;
}

Do this:

function changeHeight() {
document.getElementById('chartdiv').style.height = "200px"
}
<button type="button" onClick="changeHeight();"> Click Me!</button>

Depending on whether your php setup allows fopen on URLs, you could also simply fopen the url with the get arguments in the string (such as http://example.com?variable=value )

Edit: Re-reading the question I'm not certain whether you're looking to pass variables or not - if you're not you can simply send the fopen request containg http://example.com/filename.xml - feel free to ignore the variable=value part

As the comments mentioned, Go doesn't support ternary one liners. The shortest form I can think of is this:

var c int
if c = b; a > b {
    c = a
}

But please don't do that, it's not worth it and will only confuse people who read your code.

No need to apologize for asking a question! Try using the RIGHT function. It returns the last n characters of a string.

=RIGHT(A1, 1)

I had a similar problem, looking for grep/pattern regex and the "matched pattern found" as output.

At the end I used egrep (same regex on grep -e or -G didn't give me the same result of egrep) with the option -o

so, I think that could be something similar to (I'm NOT a regex Master) :

egrep -o "the*|this{1}|thoroughly{1}" filename

This has worked for me:

let webApiUrl = 'example.com/getStuff';
let tokenStr = 'xxyyzz';
axios.get(webApiUrl, { headers: {"Authorization" : `Bearer ${tokenStr}`} });

There are a few ways to get all unique combinations of a set of factors.

with(df, interaction(yad, per, drop=TRUE))   # gives labels
with(df, yad:per)                            # ditto

aggregate(numeric(nrow(df)), df[c("yad", "per")], length)    # gives a data frame

Recently I was trying to detect the home press button, because I needed it to do the same as the method "onBackPressed()". In order to do this, I had to override the method "onSupportNavigateUp()" like this:

override fun onSupportNavigateUp(): Boolean {
    onBackPressed()
    return true
}

It worked perfectly. =)

Well, nothing of the above answer worked for me. After a lot of research, I found a solution. Though I may be late this may help others in future.

Login to your SQL server from a terminal

 mysql -u root -p
 -- root password
GRANT ALL ON *.* to root@'XX.XXX.XXX.XX' IDENTIFIED BY 'password';

This should solve the permission issue.

Happy coding!!

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
          <Border Name="Border" Margin="0,0,0,0" Background="Transparent"
                  BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header" Margin="12,2,12,2"
                              RecognizesAccessKey="True">

If you are a Windows user and you are using conda to manage the environment in Anaconda prompt, you can do the following:

Make sure you deactivate the virtual environment or restart Anaconda Prompt. Use the following command to remove virtual environment:

$ conda env remove --name $MyEnvironmentName

Alternatively, you can go to the

C:\Users\USERNAME\AppData\Local\Continuum\anaconda3\envs\MYENVIRONMENTNAME

(that's the default file path) and delete the folder manually.

Lookarounds are zero width assertions. They check for a regex (towards right or left of the current position - based on ahead or behind), succeeds or fails when a match is found (based on if it is positive or negative) and discards the matched portion. They don't consume any character - the matching for regex following them (if any), will start at the same cursor position.

Read regular-expression.info for more details.

• Positive lookahead:

Syntax:

(?=REGEX_1)REGEX_2

Match only if REGEX_1 matches; after matching REGEX_1, the match is discarded and searching for REGEX_2 starts at the same position.

example:

(?=[a-z0-9]{4}$)[a-z]{1,2}[0-9]{2,3}

REGEX_1 is [a-z0-9]{4}$ which matches four alphanumeric chars followed by end of line.
REGEX_2 is [a-z]{1,2}[0-9]{2,3} which matches one or two letters followed by two or three digits.

REGEX_1 makes sure that the length of string is indeed 4, but doesn't consume any characters so that search for REGEX_2 starts at the same location. Now REGEX_2 makes sure that the string matches some other rules. Without look-ahead it would match strings of length three or five.

• Negative lookahead

Syntax:

(?!REGEX_1)REGEX_2

Match only if REGEX_1 does not match; after checking REGEX_1, the search for REGEX_2 starts at the same position.

example:

(?!.*\bFWORD\b)\w{10,30}$

The look-ahead part checks for the FWORD in the string and fails if it finds it. If it doesn't find FWORD, the look-ahead succeeds and the following part verifies that the string's length is between 10 and 30 and that it contains only word characters a-zA-Z0-9_

Look-behind is similar to look-ahead: it just looks behind the current cursor position. Some regex flavors like javascript doesn't support look-behind assertions. And most flavors that support it (PHP, Python etc) require that look-behind portion to have a fixed length.

• Atomic groups basically discards/forgets the subsequent tokens in the group once a token matches. Check this page for examples of atomic groups

If you are using Python > 3.x you don't need to install any libraries, this is directly built in the python framework. The old urllib2 package has been renamed to urllib:

from urllib import request

response = request.urlopen("https://www.google.com")
# set the correct charset below
page_source = response.read().decode('utf-8')
print(page_source)

It may not be running.

try runnign /etc/init.d/asterisk status

If its not running, Start it using:

/etc/init.d/asterisk start

Or in RH 7:

Systemctl start asterisk

Implementation in Go

Encode part (server -> browser)

func encode (message string) (result []byte) {
  rawBytes := []byte(message)
  var idxData int

  length := byte(len(rawBytes))
  if len(rawBytes) <= 125 { //one byte to store data length
    result = make([]byte, len(rawBytes) + 2)
    result[1] = length
    idxData = 2
  } else if len(rawBytes) >= 126 && len(rawBytes) <= 65535 { //two bytes to store data length
    result = make([]byte, len(rawBytes) + 4)
    result[1] = 126 //extra storage needed
    result[2] = ( length >> 8 ) & 255
    result[3] = ( length      ) & 255
    idxData = 4
  } else {
    result = make([]byte, len(rawBytes) + 10)
    result[1] = 127
    result[2] = ( length >> 56 ) & 255
    result[3] = ( length >> 48 ) & 255
    result[4] = ( length >> 40 ) & 255
    result[5] = ( length >> 32 ) & 255
    result[6] = ( length >> 24 ) & 255
    result[7] = ( length >> 16 ) & 255
    result[8] = ( length >>  8 ) & 255
    result[9] = ( length       ) & 255
    idxData = 10
  }

  result[0] = 129 //only text is supported

  // put raw data at the correct index
  for i, b := range rawBytes {
    result[idxData + i] = b
  }
  return
}

Decode part (browser -> server)

func decode (rawBytes []byte) string {
  var idxMask int
  if rawBytes[1] == 126 {
    idxMask = 4
  } else if rawBytes[1] == 127 {
    idxMask = 10
  } else {
    idxMask = 2
  }

  masks := rawBytes[idxMask:idxMask + 4]
  data := rawBytes[idxMask + 4:len(rawBytes)]
  decoded := make([]byte, len(rawBytes) - idxMask + 4)

  for i, b := range data {
    decoded[i] = b ^ masks[i % 4]
  }
  return string(decoded)
}

I know this thread is too old but recently I was wondering how to delete eclipse app on my MacBook Pro running macOS High Sierra.

Bellow are the steps which I followed to delete it from my system. Added screenshots for more clear understanding.

1. Open the eclipse app and it will show an app icon in dock. If it is not already present in dock then please try to run the app from Spotlight Search by pressing ? + space.

2. Now right click on that eclipse logo from dock and click Show in Finder under Options.

3. It will open the location of the eclipse app in an external finder window.

4. You can just delete the entire root directory (i.e. - eclipse) by pressing ? + delete.

5. Don't forget to delete the app from Trash as well if you are removing it from system completely.

Thanks. Hope this helped.

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

based on accepted answer

$output = some_function();
  echo $output;

if it results array then use json_encode it will result json array which is supportable by javascript

$output = some_function();
  echo json_encode($output);

If someone wants to stop execution after you echo some result use exit method of php. It will work like return keyword

$output = some_function();
  echo $output;
exit;

If you follow the steps advised in several tutorials I linked in this answer, you can get the desired effect without the somewhat complicated "manual" steps in Walker's and Vinay's answers. If you're on Ubuntu:

sudo apt-get install python-pip python-dev

The equivalent is achieved in OS X by using homebrew to install python (more details here).

brew install python

With pip installed, you can use it to get the remaining packages (you can omit sudo in OS X, as you're using your local python installation).

sudo pip install virtualenvwrapper

(these are the only packages you need installed globally and I doubt that it will clash with anything system-level from the OS. If you want to be super-safe, you can keep the distro's versions sudo apt-get install virtualenvwrapper)

Note: in Ubuntu 14.04 I receive some errors with pip install, so I use pip3 install virtualenv virtualenvwrapper and add VIRTUALENVWRAPPER_PYTHON=/usr/bin/python3 to my .bashrc/.zshrc file.

You then append to your .bashrc file

export WORKON_HOME
source /usr/local/bin/virtualenvwrapper.sh

and source it

. ~/.bashrc

This is basically it. Now the only decision is whether you want to create a virtualenv to include system-level packages

mkvirtualenv --system-site-packages foo

where your existing system packages don't have to be reinstalled, they are symlinked to the system interpreter's versions. Note: you can still install new packages and upgrade existing included-from-system packages without sudo - I tested it and it works without any disruptions of the system interpreter.

kermit@hocus-pocus:~$ sudo apt-get install python-pandas
kermit@hocus-pocus:~$ mkvirtualenv --system-site-packages s
(s)kermit@hocus-pocus:~$ pip install --upgrade pandas
(s)kermit@hocus-pocus:~$ python -c "import pandas; print(pandas.__version__)"
0.10.1
(s)kermit@hocus-pocus:~$ deactivate
kermit@hocus-pocus:~$ python -c "import pandas; print(pandas.__version__)"
0.8.0

The alternative, if you want a completely separated environment, is

mkvirtualenv --no-site-packages bar

or given that this is the default option, simply

mkvirtualenv bar

The result is that you have a new virtualenv where you can freely and sudolessly install your favourite packages

pip install flask

So some days I lack brain cells and:

<android.support.v7.widget.SwitchCompat
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        style="@style/CustomSwitchStyle"/>

does not apply the theme because style is incorrect. I was supposed to use app:theme :P

<android.support.v7.widget.SwitchCompat
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:theme="@style/CustomSwitchStyle"/>

Whoopsies. This post was what gave me insight into my mistake...hopefully if someone stumbles across this it will help them like it did me. Thank you Gaëtan Maisse for your answer

The R file can't be generated if your layout contains errors. If your res folder is empty, then it's safe to assume that there's no res/layout folder with any layouts in it, but your activity is probably calling setContentView and not finding anything -- that qualifies as a problem with your layout.

Well I would do it like this instead:

TimeSpan diff = expiryDate - DateTime.Today;
if (diff.Days > 30) 
   matchFound = true;

Compare only responds with an integer indicating weather the first is earlier, same or later...

If you have an Activity object hanging around, you can use the isDestroyed() method:

Activity activity;

// ...

if (!activity.isDestroyed()) {
    // ...
}

This is nice if you have a non-anonymous AsyncTask subclass that you use in various places.

What moves origin/HEAD "organically"?

• git clone sets it once to the spot where HEAD is on origin
  • it serves as the default branch to checkout after cloning with git clone

What does HEAD on origin represent?

• on bare repositories (often repositories “on servers”) it serves as a marker for the default branch, because git clone uses it in such a way
• on non-bare repositories (local or remote), it reflects the repository’s current checkout

What sets origin/HEAD?

• git clone fetches and sets it
• it would make sense if git fetch updates it like any other reference, but it doesn’t
• git remote set-head origin -a fetches and sets it
  • useful to update the local knowledge of what remote considers the “default branch”

Trivia

• origin/HEAD can also be set to any other value without contacting the remote: git remote set-head origin <branch>
  • I see no use-case for this, except for testing
• unfortunately nothing is able to set HEAD on the remote
• older versions of git did not know which branch HEAD points to on the remote, only which commit hash it finally has: so it just hopefully picked a branch name pointing to the same hash

Very easy no need create class extends LocationListener 1- Variable

private LocationManager mLocationManager;
private LocationListener mLocationListener;
private static double currentLat =0;
private static double currentLon =0;

2- onStartService()

@Override public void onStartService() {
    addListenerLocation();
}

3- Method addListenerLocation()

 private void addListenerLocation() {
    mLocationManager = (LocationManager)
            getSystemService(Context.LOCATION_SERVICE);
    mLocationListener = new LocationListener() {
        @Override
        public void onLocationChanged(Location location) {
            currentLat = location.getLatitude();
            currentLon = location.getLongitude();

            Toast.makeText(getBaseContext(),currentLat+"-"+currentLon, Toast.LENGTH_SHORT).show();

        }

        @Override
        public void onStatusChanged(String provider, int status, Bundle extras) {
        }

        @Override
        public void onProviderEnabled(String provider) {
            Location lastKnownLocation = mLocationManager.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
            if(lastKnownLocation!=null){
                currentLat = lastKnownLocation.getLatitude();
                currentLon = lastKnownLocation.getLongitude();
            }

        }

        @Override
        public void onProviderDisabled(String provider) {
        }
    };
    mLocationManager.requestLocationUpdates(
            LocationManager.GPS_PROVIDER, 500, 10, mLocationListener);
}

4- onDestroy()

@Override
public void onDestroy() {
    super.onDestroy();
    mLocationManager.removeUpdates(mLocationListener);
}

Try using this instead:

var latitude = results[0].geometry.location.lat();
var longitude = results[0].geometry.location.lng();

It's bit hard to navigate Google's api but here is the relevant documentation.

One thing I had trouble finding was how to go in the other direction. From coordinates to an address. Here is the code I neded upp using. Please not that I also use jquery.

$.each(results[0].address_components, function(){
    $("#CreateDialog").find('input[name="'+ this.types+'"]').attr('value', this.long_name);
});

What I'm doing is to loop through all the returned address_components and test if their types match any input element names I have in a form. And if they do I set the value of the element to the address_components value.
If you're only interrested in the whole formated address then you can follow Google's example

Action: Start a Program

Program/script: C:\Windows\System32\cmd.exe

Add arguments: /k start "" "E:\scripts\example.bat"

Add exit to the end of your batch file.

The cmd window will not show if you select Run whether user is logged in or not. You need to select Run only when user is logged on to see the window in action.

If you want to take a component class as a parameter (vs an instance), use React.ComponentClass:

function renderGreeting(Elem: React.ComponentClass<any>) {
    return <span>Hello, <Elem />!</span>;
}

String is present in package java.lang which is imported by default in all java programs.

Something like this:

$.getJSON("http://mywebsite.com/json/get.php?cid=15",
        function(data){
          $.each(data.products, function(i,product){
            content = '<p>' + product.product_title + '</p>';
            content += '<p>' + product.product_short_description + '</p>';
            content += '<img src="' + product.product_thumbnail_src + '"/>';
            content += '<br/>';
            $(content).appendTo("#product_list");
          });
        });

Would take a json object made from a PHP array returned with the key of products. e.g:

Array('products' => Array(0 => Array('product_title' => 'Product 1',
                                     'product_short_description' => 'Product 1 is a useful product',
                                     'product_thumbnail_src' => '/images/15/1.jpg'
                                    )
                          1 => Array('product_title' => 'Product 2',
                                     'product_short_description' => 'Product 2 is a not so useful product',
                                     'product_thumbnail_src' => '/images/15/2.jpg'
                                    )
                         )
     )

To reload the list you would simply do:

$("#product_list").empty();

And then call getJSON again with new parameters.

mongo => mongo-db console
mongodb => mongo-db server

If you're on Mac and looking for a easier way to start/stop your mongo-db server, then MongoDB Preference Pane is something that you should look into. With it, you start/stop your mongo-db instance via UI. Hope it helps!

To take input " long int " and output " long int " in C is :

long int n;
scanf("%ld", &n);
printf("%ld", n);

To take input " long long int " and output " long long int " in C is :

long long int n;
scanf("%lld", &n);
printf("%lld", n);

Hope you've cleared..

You could use prop as well. Check the following code below.

$(document).ready(function(){

   $('.staff_on_site').click(function(){

     var rBtnVal = $(this).val();

     if(rBtnVal == "yes"){
         $("#no_of_staff").prop("readonly", false); 
     }
     else{ 
         $("#no_of_staff").prop("readonly", true); 
     }
   });
});

I know this has already been answered, but here is an example for the people who are trying to use SQL Server Types in a vb project:

            Imports System
            Imports System.IO
            Imports System.Runtime.InteropServices

            Namespace SqlServerTypes
                Public Class Utilities



                    <DllImport("kernel32.dll", CharSet:=CharSet.Auto, SetLastError:=True)>
                    Public Shared Function LoadLibrary(ByVal libname As String) As IntPtr

                    End Function

                    Public Shared Sub LoadNativeAssemblies(ByVal rootApplicationPath As String)
                        Dim nativeBinaryPath = If(IntPtr.Size > 4, Path.Combine(rootApplicationPath, "SqlServerTypes\x64\"), Path.Combine(rootApplicationPath, "SqlServerTypes\x86\"))
                        LoadNativeAssembly(nativeBinaryPath, "msvcr120.dll")
                        LoadNativeAssembly(nativeBinaryPath, "SqlServerSpatial140.dll")
                    End Sub

                    Private Shared Sub LoadNativeAssembly(ByVal nativeBinaryPath As String, ByVal assemblyName As String)
                        Dim path = System.IO.Path.Combine(nativeBinaryPath, assemblyName)
                        Dim ptr = LoadLibrary(path)

                        If ptr = IntPtr.Zero Then
                            Throw New Exception(String.Format("Error loading {0} (ErrorCode: {1})", assemblyName, Marshal.GetLastWin32Error()))
                        End If
                    End Sub
                End Class
            End Namespace

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

Firstly, it's necessary to know what is a jar file.

From Oracle,

JAR (Java Archive) is a platform-independent file format that aggregates many files into one. Multiple Java applets and their requisite components (.class files, images and sounds) can be bundled in a JAR file and subsequently downloaded to a browser in a single HTTP transaction, greatly improving the download speed. The JAR format also supports compression, which reduces the file size, further improving the download time.

As you can see,

1. It has nothing to do with a Eclipse project. An Eclipse project can be a Java project, C++ project and so on. It's just a self contain project that can be recognized and operated as an unit by Eclipse.
2. The .class files are generally the main part of a jar file. It's impossible to view the source code(.java file) unless you decompile the executable file(.class file) by some tools. Take Eclipse for example, you can choose the plugin Eclipse Class Decompiler as the tool.

In my case it was due to 'lower_case_table_names' parameter.

The error number 39 thrown out when I tried to drop the databases which consists upper case table names with lower_case_table_names parameter is enabled.

This is fixed by reverting back the lower case parameter changes to the previous state.

If your CORS settings do not help you.

Verify the configuration S3 is correct. I had an invalid bucket name in Storage.configure. I used a short name of bucket and it caused an error:

No 'Access-Control-Allow-Origin' header is present on the requested resource.

I encounter same error, and incognito mode also has same issue. I resolve this issue by clear Chrome history.

You are not adding the object to the session, instead you are adding it to the request.
What you need is:

HttpSession session = request.getSession();
session.setAttribute("MySessionVariable", param);

In Servlets you have 4 scopes where you can store data.

1. Application
2. Session
3. Request
4. Page
