I stumbled across this for the same reason as anyone else. But the quoted scripts didn't quite work for me. I've made one that is more a hybrid of those I've seen and it now lives here - https://gitlab.com/inorton/git-size-calc

This code will help you out:-

- (NSString *)getFileName:(UIImageView *)imgView{
    NSString *imgName = [imgView image].accessibilityIdentifier;
    NSLog(@"%@",imgName);
    return imgName;
}

Use this as:-

NSString *currentImageName = [self getFileName:MyIImageView];

If (as I understand) you're trying to completely block inheritance in the web config of your child application, I suggest you to avoid using the tag in web.config. Instead create a new apppool and edit the applicationHost.config file (located in %WINDIR%\System32\inetsrv\Config and %WINDIR%\SysWOW64\inetsrv\config). You just have to find the entry for your apppool and add the attribute enableConfigurationOverride="false" like in the following example:

<add name="MyAppPool" autoStart="true" managedRuntimeVersion="v4.0" managedPipelineMode="Integrated" enableConfigurationOverride="false">
    <processModel identityType="NetworkService" />
</add>

This will avoid configuration inheritance in the applications served by MyAppPool.

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

You can see if object has shape or not

def check_array(x):
    try:
        x.shape
        return True
    except:
        return False

I found this related question: Directory Listing in S3 Static Website

As it turns out, if you enable public read for the whole bucket, S3 can serve directory listings. Problem is they are in XML instead of HTML, so not very user-friendly.

There are three ways you could go for generating listings:

• Generate index.html files for each directory on your own computer, upload them to s3, and update them whenever you add new files to a directory. Very low-tech. Since you're saying you're uploading build files straight from Travis, this may not be that practical since it would require doing extra work there.

• Use a client-side S3 browser tool.

  • s3-bucket-listing by Rufus Pollock
  • s3-file-list-page by Adam Pritchard

• Use a server-side browser tool.

  • s3browser (PHP)
  • s3index Scala. Going by the existence of a Procfile, it may be readily deployable to Heroku. Not sure since I don't have any experience with Scala.

Something like this should do it:

for element in list_:
   sys.stdout.write(str(element))

I will share that How do I do it since Java 7 -

Long first = 12345L, second = 123L;
System.out.println(first.equals(second));

output returned : false

and second example of match is -

Long first = 12345L, second = 12345L;
System.out.println(first.equals(second));

output returned : true

So, I believe in equals method for comparing Object's value, Hope it helps you, thanks.

const something = { bar: "Foobar!" };
const foo = 'bar';

something[\`${foo}\`];

You can still use the Screen class from a WPF app. You just need to reference the System.Windows.Forms assembly from your application. Once you've done that, (and referenced System.Drawing for the example below):

Rectangle workingArea = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea;

...works just fine.

Have you considered setting your main window property WindowStartupLocation to CenterScreen?

Getting encoding right is really tricky - there are too many layers:

• Browser
• Page
• PHP
• MySQL

The SQL command "SET CHARSET utf8" from PHP will ensure that the client side (PHP) will get the data in utf8, no matter how they are stored in the database. Of course, they need to be stored correctly first.

DDL definition vs. real data

Encoding defined for a table/column doesn't really mean that the data are in that encoding. If you happened to have a table defined as utf8 but stored as differtent encoding, then MySQL will treat them as utf8 and you're in trouble. Which means you have to fix this first.

What to check

You need to check in what encoding the data flow at each layer.

• Check HTTP headers, headers.
• Check what's really sent in body of the request.
• Don't forget that MySQL has encoding almost everywhere:
  • Database
  • Tables
  • Columns
  • Server as a whole
  • Client
    Make sure that there's the right one everywhere.

Conversion

If you receive data in e.g. windows-1250, and want to store in utf-8, then use this SQL before storing:

SET NAMES 'cp1250';

If you have data in DB as windows-1250 and want to retreive utf8, use:

SET CHARSET 'utf8';

Few more notes:

• Don't rely on too "smart" tools to show the data. E.g. phpMyAdmin does (was doing when I was using it) encoding really bad. And it goes through all the layers so it's hard to find out.
• Also, Internet Explorer had really stupid behavior of "guessing" the encoding based on weird rules.
• Use simple editors where you can switch encoding. I recommend MySQL Workbench.

For Internet Explorer, there is another solution:

1. Open internet explorer.
2. Click menu > tools > internet options.
3. Click general > temporary internet files > "settings" button.
4. Click "view files" button.
5. Find your old favicon.ico file and delete it.
6. Restart browser(internet explorer).

This is old, but someone else may stumble on it as I did. When you connect to the DataCast, you are talking to a daemon that can access the database. It was intended that a customer would write some code to access the database and store the results somewhere. It just happens that telnet works to access data manually. netcat should also work. ssh obviously will not.

Simply put a file named favicon.ico in the webroot.

If you want to know more, please start reading:

• Favicon on Wikipedia
• Favicon Generator
• How to add a Favicon by W3C (from 2005 though)

When you create an initialization of the ResourceBundle, you can do this way also.

For testing and development I have created a properties file under \src with the name prp.properties.

Use this way:

ResourceBundle rb = ResourceBundle.getBundle("prp");

Naming convention and stuff:

PHP-ZIP needs some dependancies or library missing, depends on the image from Dockerfile you need to install them first

RUN set -eux \
   && apt-get update \
   && apt-get install -y libzip-dev zlib1g-dev \
   && docker-php-ext-install zip

list[-1] will retrieve the last element of the list without changing the list. list.pop() will retrieve the last element of the list, but it will mutate/change the original list. Usually, mutating the original list is not recommended.

Alternatively, if, for some reason, you're looking for something less pythonic, you could use list[len(list)-1], assuming the list is not empty.

Actually in newer Osx os's, this is stored in /Library/WebServer/Documents/

The .en file is just an html file, but it needs special permissions to change, so I just made a folder for my stuff and then accessed it by user.local/Folder/file.html

You can not ask for instance during configuration phase - you can ask only for providers.

var app = angular.module('modx', []);

// configure stuff
app.config(function($routeProvider, $locationProvider) {
  // you can inject any provider here
});

// run blocks
app.run(function($rootScope) {
  // you can inject any instance here
});

See http://docs.angularjs.org/guide/module for more info.

I agree with both previous answers. Basically, you want to use what is known as a "lightbox" - http://en.wikipedia.org/wiki/Lightbox_(JavaScript)

It is essentially a div than is created within the DOM of your current window/tab. In addition to the div that contains your dialog, a transparent overlay blocks the user from engaging all underlying elements. This can effectively create a modal dialog (i.e. user MUST make some kind of decision before moving on).

Another way to do this, although equally unsatisfying is:

s = pd.Series([1,3,0,7,5],index=[0,1,2,3,4])

list(s).index(7)

returns: 3

On time tests using a current dataset I'm working with (consider it random):

[64]:    %timeit pd.Index(article_reference_df.asset_id).get_loc('100000003003614')
10000 loops, best of 3: 60.1 µs per loop

In [66]: %timeit article_reference_df.asset_id[article_reference_df.asset_id == '100000003003614'].index[0]
1000 loops, best of 3: 255 µs per loop


In [65]: %timeit list(article_reference_df.asset_id).index('100000003003614')
100000 loops, best of 3: 14.5 µs per loop

Usually you want dates to be presented to each user in his own local time-

that is why we use GMT (UTC).

Use Date.parse(jsondatestring) to get the local time string,

unless you want your local time shown to each visitor.

In that case, use Anatoly's method.

If you want the time as well, just go with

datetime.datetime.now().__str__()

Prints 2019-07-11 19:36:31.118766 in console for me

What do we mean by org.hibernate.exception.SQLGrammarException?

Implementation of JDBCException indicating that the SQL sent to the database server was invalid (syntax error, invalid object references, etc).

and in my words there is a kind of Grammar mistake inside of your hibernate.cfg.xml configuration file,

it happens when you write wrong schema defination property name inside, like below example:

<property name="hibernate.connection.hbm2ddl.auto">create</property>

which supposed to be like:

<property name="hibernate.hbm2ddl.auto">create</property>

CSS can be applied and you will have to set transform-origin correctly to get the applied transformation in the way you want

See the fiddle:

http://jsfiddle.net/OMS_/gkrsz/

Main code:

/* assuming that the image's height is 70px */

img.rotated {
    transform: rotate(90deg);
    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -ms-transform: rotate(90deg);

    transform-origin: 35px 35px;
    -webkit-transform-origin: 35px 35px;
    -moz-transform-origin: 35px 35px;
    -ms-transform-origin: 35px 35px;
}

jQuery and JS:

$(img)
    .css('transform-origin-x', imgWidth / 2)
    .css('transform-origin-y', imgHeight / 2);

// By calculating the height and width of the image in the load function

// $(img).css('transform-origin', (imgWidth / 2) + ' ' + (imgHeight / 2) );

Logic:

Divide the image's height by 2. The transform-x and transform-y values should be this value

Usually 'lost' is a euphemism for "We stopped paying the developer and now he wont give us the source code."

That being said, I own a copy of Burak's ActionScript Viewer, and it works pretty well. A simple google search will find you many other SWF decompilers.

Hard links are very useful when doing incremental backups. See rsnapshot, for example. The idea is to do copy using hard links:

• copy backup number n to n + 1
• copy backup n - 1 to n
• ...
• copy backup 0 to backup 1
• update backup 0 with any changed files.

The new backup will not take up any extra space apart from any changes you've made, since all the incremental backups will point to the same set of inodes for files which haven't changed.

Very simple difference, If you just want to see the structure of your project then go for export.

And if you want to work on your files then you need to checkout as it will include the .svn folder which contains the metadata which makes the working copy, else you get the error in export.

If you do svn export and then edit some files and then commit, then you will get an error:

../../xxx is not your working copy.

You need to specify it on the methods that can throw the exceptions. You just seperate them with a ',' if it can throw more than 1 type of exception. e.g.

public interface MyInterface {
  public MyObject find(int x) throws MyExceptionA,MyExceptionB;
}

Use "ssh-keygen -p". You can add "-f "

It will prompt you for the old password. If the password is correct, it will prompt to enter a new password. If the old password is incorrect, you will get "Failed to load key <...>".

Take a Look at this Plugin

Makes your code as easy as -> $('SelectorToPrint').printElement();

I think you could do it by creating parameters in an object maybe?

var myObject = {}; for(var i=0;i<myArray.length;i++) {     myObject[ myArray[i] ]; } 

If you don't set them to anything, you'll just have an object with some parameters that are undefined. I'd have to write this myself to be sure though.

you can't have a saved python file called nltk.py because the interpreter is reading from that and not from the actual file.

Change the name of your file that the python shell is reading from and try what you were doing originally:

import nltk and then nltk.download()

Either you can use the accessors provided by the Web Storage API or you could write a wrapper/adapter. From your stated issue with defineGetter/defineSetter is sounds like writing a wrapper/adapter is too much work for you.

I honestly don't know what to tell you. Maybe you could reevaluate your opinion of what is a "ridiculous limitation". The Web Storage API is just what it's supposed to be, a key/value store.

If you were open to using JQuery, you could modify the background color for any link that has the property aria-expanded set to true by doing the following...

$("a[aria-expanded='true']").css("background-color", "#42DCA3");

Depending on how specific you want to be regarding which links this applies to, you may have to slightly modify your selector.

#pragma mark - NSSecureCoding

The main purpose of "pragma" is for developer reference.

You can easily find a method/Function in a vast thousands of coding lines.

Xcode 11+:

Marker Line in Top

// MARK: - Properties

Marker Line in Top and Bottom

// MARK: - Properties - 

Marker Line only in bottom

// MARK: Properties -

Do:

con.query('SET GLOBAL connect_timeout=28800')
con.query('SET GLOBAL interactive_timeout=28800')
con.query('SET GLOBAL wait_timeout=28800')

Parameter meaning (taken from MySQL Workbench in Navigator: Instance > Options File > Tab "Networking" > Section "Timeout Settings")

• connect_timeout: Number of seconds the mysqld server waits for a connect packet before responding with 'Bad handshake'
• interactive_timeout Number of seconds the server waits for activity on an interactive connection before closing it
• wait_timeout Number of seconds the server waits for activity on a connection before closing it

BTW: 28800 seconds are 8 hours, so for a 10 hour execution time these values should be actually higher.

First is you have to understand the difference between MyISAM and InnoDB Engines. And this is clearly stated on this link. You can use this sql statement if you want to convert InnoDB to MyISAM:

 ALTER TABLE t1 ENGINE=MyISAM;

I've used a few CSS hacks and targeted Chrome/Safari/Firefox/IE individually, as each browser renders selects a bit differently. I've tested on all browsers except IE.

For Safari/Chrome, set the height and line-height you want for your <select />.

For Firefox, we're going to kill Firefox's default padding and border, then set our own. Set padding to whatever you like.

For IE 8+, just like Chrome, we've set the height and line-height properties. These two media queries can be combined. But I kept it separate for demo purposes. So you can see what I'm doing.

Please note, for the height/line-height property to work in Chrome/Safari OSX, you must set the background to a custom value. I changed the color in my example.

Here's a jsFiddle of the below: http://jsfiddle.net/URgCB/4/

For the non-hack route, why not use a custom select plug-in via jQuery? Check out this: http://codepen.io/wallaceerick/pen/ctsCz

HTML:

<select>
    <option>Here's one option</option>
    <option>here's another option</option>
</select>

CSS:

@media screen and (-webkit-min-device-pixel-ratio:0) {  /*safari and chrome*/
    select {
        height:30px;
        line-height:30px;
        background:#f4f4f4;
    } 
}
select::-moz-focus-inner { /*Remove button padding in FF*/ 
    border: 0;
    padding: 0;
}
@-moz-document url-prefix() { /* targets Firefox only */
    select {
        padding: 15px 0!important;
    }
}        
@media screen\0 { /* IE Hacks: targets IE 8, 9 and 10 */        
    select {
        height:30px;
        line-height:30px;
    }     
}

If the behavior of for(... in ...) is acceptable/necessary for your purposes, you can tell tslint to allow it.

in tslint.json, add this to the "rules" section.

"forin": false

Otherwise, @Maxxx has the right idea with

for (const field of Object.keys(this.formErrors)) {

Use (keyup.enter).

Angular can filter the key events for us. Angular has a special syntax for keyboard events. We can listen for just the Enter key by binding to Angular's keyup.enter pseudo-event.

Another option would be to use a keyed data.table:

library(data.table)
setDT(dt, key = 'fct')[J(vc)]  # or: setDT(dt, key = 'fct')[.(vc)]

which results in:

   fct X
1:   a 2
2:   a 7
3:   a 1
4:   c 3
5:   c 5
6:   c 9
7:   c 2
8:   c 4

What this does:

• setDT(dt, key = 'fct') transforms the data.frame to a data.table (which is an enhanced form of a data.frame) with the fct column set as key.
• Next you can just subset with the vc vector with [J(vc)].

NOTE: when the key is a factor/character variable, you can also use setDT(dt, key = 'fct')[vc] but that won't work when vc is a numeric vector. When vc is a numeric vector and is not wrapped in J() or .(), vc will work as a rowindex.

A more detailed explanation of the concept of keys and subsetting can be found in the vignette Keys and fast binary search based subset.

An alternative as suggested by @Frank in the comments:

setDT(dt)[J(vc), on=.(fct)]

When vc contains values that are not present in dt, you'll need to add nomatch = 0:

setDT(dt, key = 'fct')[J(vc), nomatch = 0]

or:

setDT(dt)[J(vc), on=.(fct), nomatch = 0]

I use inline if's

($_POST['category'] == $data['id'] ? 'selected="selected"' : false)

Got it working with

Actions builder = new Actions(driver);
WebElement el = some element;
builder.keyDown(Keys.CONTROL)
.moveByOffset( 10, 25 )
.clickAndHold(el)
.build().perform();

Using javascript, you can set tooltips for all the images on the page.

<!DOCTYPE html>
<html>
    <body>
    <img src="http://sushmareddy.byethost7.com/dist/img/buffet.png" alt="Food">
    <img src="http://sushmareddy.byethost7.com/dist/img/uthappizza.png" alt="Pizza">
     <script>
     //image objects
     var imageEls = document.getElementsByTagName("img");
     //Iterating
     for(var i=0;i<imageEls.length;i++){
        imageEls[i].title=imageEls[i].alt;
        //OR
        //imageEls[i].title="Title of your choice";
     }
        </script>
    </body>
</html>

It is not possible in on step or you need to keep the reference to the array. If you can change the reference this can help:

      String[] n = new String[]{"google","microsoft","apple"};
      final List<String> list =  new ArrayList<String>();
      Collections.addAll(list, n); 
      list.remove("apple");
      n = list.toArray(new String[list.size()]);

I not recommend the following but if you worry about performance:

      String[] n = new String[]{"google","microsoft","apple"};
      final String[] n2 = new String[2]; 
      System.arraycopy(n, 0, n2, 0, n2.length);
      for (int i = 0, j = 0; i < n.length; i++)
      {
        if (!n[i].equals("apple"))
        {
          n2[j] = n[i];
          j++;
        }      
      }

I not recommend it because the code is a lot more difficult to read and maintain.

For windows open git bash and try

NODE_ENV=production node app.js

Assuming C++11, here is a one-liner loop body, if this is consistent with your programming style:

using Map = std::map<K,V>;
Map map;

// Erase members that satisfy needs_removing(itr)
for (Map::const_iterator itr = map.cbegin() ; itr != map.cend() ; )
  itr = needs_removing(itr) ? map.erase(itr) : std::next(itr);

A couple of other minor style changes:

• Show declared type (Map::const_iterator) when possible/convenient, over using auto.
• Use using for template types, to make ancillary types (Map::const_iterator) easier to read/maintain.

You can use coalesce(column_name,0) instead of just column_name. The coalesce function returns the first non-NULL value in the list.

I should mention that per-row functions like this are usually problematic for scalability. If you think your database may get to be a decent size, it's often better to use extra columns and triggers to move the cost from the select to the insert/update.

This amortises the cost assuming your database is read more often than written (and most of them are).

Updated with Swift 5 Generally we use three type of Local Notifications

1. Simple Local Notification
2. Local Notification with Action
3. Local Notification with Content

Where you can send simple text notification or with action button and attachment.

Using UserNotifications package in your app, the following example Request for notification permission, prepare and send notification as per user action AppDelegate itself, and use view controller listing different type of local notification test.

AppDelegate

import UIKit
import UserNotifications

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate, UNUserNotificationCenterDelegate {

        //Confirm Delegete and request for permission
        notificationCenter.delegate = self
        let options: UNAuthorizationOptions = [.alert, .sound, .badge]
        notificationCenter.requestAuthorization(options: options) {
            (didAllow, error) in
            if !didAllow {
                print("User has declined notifications")
            }

    let notifications = ["Simple Local Notification",
                         "Local Notification with Action",

The use of CultureInfo class worked for me, I hope help you.

    string value = "1200.00";
    CultureInfo culture = new CultureInfo("en-US");
    decimal result = Convert.ToDecimal(value, culture);

JS .trim() is supported in basically everthing, except IE 8 and below.

If you want it to work with that, then, you can use JQuery, but it'll need to be <2.0.0 (as they removed support for IE8 in the 2.x.x line).

Your other option, if you care about IE7/8 (As you mention earlier), is to add trim yourself:

if(typeof String.prototype.trim !== 'function') {
  String.prototype.trim = function() {
    return this.replace(/^\s+|\s+$/g, ''); 
  }
}

You should only need to do a single join:

SELECT e.Grade, v.Score, e.CaseNum, e.FileNum, e.ActivityNum
FROM Evaluation e
INNER JOIN Value v ON e.CaseNum = v.CaseNum AND e.FileNum = v.FileNum AND e.ActivityNum = v.ActivityNum

You can simply do:

base=$(basename "$fspec")

The term ABI is used to refer to two distinct but related concepts.

When talking about compilers it refers to the rules used to translate from source-level constructs to binary constructs. How big are the data types? how does the stack work? how do I pass parameters to functions? which registers should be saved by the caller vs the callee?

When talking about libraries it refers to the binary interface presented by a compiled library. This interface is the result of a number of factors including the source code of the library, the rules used by the compiler and in some cases definitions picked up from other libraries.

Changes to a library can break the ABI without breaking the API. Consider for example a library with an interface like.

void initfoo(FOO * foo)
int usefoo(FOO * foo, int bar)
void cleanupfoo(FOO * foo)

and the application programmer writes code like

int dostuffwithfoo(int bar) {
  FOO foo;
  initfoo(&foo);
  int result = usefoo(&foo,bar)
  cleanupfoo(&foo);
  return result;
}

The application programmer doesn't care about the size or layout of FOO, but the application binary ends up with a hardcoded size of foo. If the library programmer adds an extra field to foo and someone uses the new library binary with the old application binary then the library may make out of bounds memory accesses.

OTOH if the library author had designed their API like.

FOO * newfoo(void)
int usefoo(FOO * foo, int bar)
void deletefoo((FOO * foo, int bar))

and the application programmer writes code like

int dostuffwithfoo(int bar) {
  FOO * foo;
  foo = newfoo();
  int result = usefoo(foo,bar)
  deletefoo(foo);
  return result;
}

Then the application binary does not need to know anything about the structure of FOO, that can all be hidden inside the library. The price you pay for that though is that heap operations are involved.

The pseudo-elements generated by ::before and ::after are contained by the element's formatting box, and thus don't apply to replaced elements such as img, or to br elements.

https://developer.mozilla.org/en-US/docs/Web/CSS/::after

They are the same (as is the third form, ^=).

Note, though, that they are still considered different from the point of view of the parser, that is a stored outline defined for a != won't match <> or ^=.

This is unlike PostgreSQL where the parser treats != and <> yet on parsing stage, so you cannot overload != and <> to be different operators.

feel so stupid - (for whatever reason) i had one empty xml in drawable folder. and AS produced dozens of unrelated errors ><

so, my general advice would be the same - check briefly every resource file.

You can use SpicyTaco.AutoGrid - a modified version of StackPanel:

<st:StackPanel Orientation="Horizontal" MarginBetweenChildren="10" Margin="10">
   <Button Content="Info" HorizontalAlignment="Left" st:StackPanel.Fill="Fill"/>
   <Button Content="Cancel"/>
   <Button Content="Save"/>
</st:StackPanel>

First button will be fill.

You can install it via NuGet:

Install-Package SpicyTaco.AutoGrid

I recommend taking a look at SpicyTaco.AutoGrid. It's very useful for forms in WPF instead of DockPanel, StackPanel and Grid and solve problem with stretching very easy and gracefully. Just look at readme on GitHub.

<st:AutoGrid Columns="160,*" ChildMargin="3">
    <Label Content="Name:"/>
    <TextBox/>

    <Label Content="E-Mail:"/>
    <TextBox/>

    <Label Content="Comment:"/>
    <TextBox/>
</st:AutoGrid>

TLS (Transport Level Security) is the slightly broader term that has replaced SSL (Secure Sockets Layer) in securing HTTP communications. So what you are being asked to do is enable SSL.

I think the quick and dirty answer is that

• LINQ to SQL is the quick-and-easy way to do it. This means you will get going quicker, and deliver quicker if you are working on something smaller.
• Entity Framework is the all-out, no-holds-barred way to do it. This means you will take more time up-front, develop slower, and have more flexibility if you are working on something larger.

You can do it using $.ajax or $.post

Using $.ajax :

    $.ajax({
      type: 'post',
      url: 'superman',
      data: { 
        'field1': 'hello', 
        'field2': 'hello1'
      },
      success: function (response) {
        alert(response.status);
      },
      error: function () {
        alert("error");
      }
   });

Using $.post :

    $.post('superman',
      { 
        'field1': 'hello', 
        'field2': 'hello1'
      },
      function (response, status) {
        alert(response.status);
      }
    );

As some answers have pointed out, sometimes you really want to delete the local repository entirely, for example, there might be some artifacts that can't be purged as they are not anymore referenced by the pom.

If you want to have this deletion embedded in a maven phase, as for example clean you can use the maven-clean-plugin and access the repository through the settings, for example:

 <plugin>
    <inherited>false</inherited>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.1</version>
    <executions>
        <execution>
            <phase>clean</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <tasks>
                    <echo>Base clean is attached to deleting local maven cache</echo>
                    <echo>${settings.localRepository}</echo>
                </tasks>
            </configuration>
        </execution>
    </executions>
</plugin>

<plugin>
    <inherited>false</inherited>
    <artifactId>maven-clean-plugin</artifactId>
    <version>3.1.0</version>
    <configuration>
        <filesets>
            <fileset>
                <directory>${settings.localRepository}</directory>
            </fileset>
        </filesets>
    </configuration>
</plugin>

• Install the required version of Windows SDK or change the SDK version in the project property pages

  or

• by right-clicking the solution and selecting "Retarget solution"

If you do visual studio guide, you will resolve the problem.

You could define a macro containing the following code:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.ClearContents
end sub

Running the macro would select the range A5:x50 on the active worksheet and clear all the contents of the cells within that range.

To leave your formulas intact use the following instead:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.SpecialCells(xlCellTypeConstants, 23).Select
    Selection.ClearContents
end sub

This will first select the overall range of cells you are interested in clearing the contents from and will then further limit the selection to only include cells which contain what excel considers to be 'Constants.'

You can do this manually in excel by selecting the range of cells, hitting 'f5' to bring up the 'Go To' dialog box and then clicking on the 'Special' button and choosing the 'Constants' option and clicking 'Ok'.

use return before calling the function, while you click the submit button, two events(form posting as you used submit button and function call for onclick) will happen, to prevent form posting you have to return false, you have did it, also you have to specify the return i.e, to expect a value from the function,

this is a code:

input type="submit" name="continue" value="submit" onClick="**return** checkform();"

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

You don't necessarily need to have the parameters inside the URL.

For instance, with:

$stateProvider
.state('home', {
  url: '/',
  views: {
    '': {
      templateUrl: 'home.html',
      controller: 'MainRootCtrl'

    },
  },
  params: {
    foo: null,
    bar: null
  }
})

You will be able to send parameters to the state, using either:

$state.go('home', {foo: true, bar: 1});
// or
<a ui-sref="home({foo: true, bar: 1})">Go!</a>

Of course, if you reload the page once on the home state, you will loose the state parameters, as they are not stored anywhere.

A full description of this behavior is documented here, under the params row in the state(name, stateConfig) section.

For a non-volatile solution, how about for 2007+:

for cell    =INDEX($A$1:$XFC$1048576,ROW(),COLUMN())
for column  =INDEX($A$1:$XFC$1048576,0,COLUMN())
for row     =INDEX($A$1:$XFC$1048576,ROW(),0)

I have weird bug on Excel 2010 where it won't accept the very last row or column for these formula (row 1048576 & column XFD), so you may need to reference these one short. Not sure if that's the same for any other versions so appreciate feedback and edit.

and for 2003 (INDEX became non-volatile in '97):

for cell    =INDEX($A$1:$IV$65536,ROW(),COLUMN())
for column  =INDEX($A$1:$IV$65536,0,COLUMN())
for row     =INDEX($A$1:$IV$65536,ROW(),0)

I've preferred using the params filter for parameter-centric content-type.. I believe that should work in conjunction with the produces attribute.

@GetMapping(value="/person/{id}/", 
            params="format=json",
            produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Person> getPerson(@PathVariable Integer id){
    Person person = personMapRepository.findPerson(id);
    return ResponseEntity.ok(person);
} 
@GetMapping(value="/person/{id}/", 
            params="format=xml",
            produces=MediaType.APPLICATION_XML_VALUE)
public ResponseEntity<Person> getPersonXML(@PathVariable Integer id){
    return GetPerson(id); // delegate
}

Karate is exactly what you are looking for. Here is an example:

* def myJson = { foo: 'world', hey: 'ho', zee: [5], cat: { name: 'Billie' } }

Basically the same as bcoughlan's answer, but here it is as an executable command:

$ python -c "import django; print(django.get_version())"

The solution I came up with is basically the same solution used before the introduction of storyboards.

Create a new, empty interface class file. Drag a UIView on to the canvas, layout as desired.

Load the nib manually, assign to the appropriate header/footer section in viewForHeaderInSection or viewForFooterInSection delegate methods.

I had hope that Apple simplified this scenario with storyboards and kept looking for a better or simpler solution. For example custom table headers and footers are straight forward to add.

Use the double-star (aka double-splat?) operator:

func(**{'type':'Event'})

is equivalent to

func(type='Event')

This is due to staticmethod being a descriptor and requires a class-level attribute fetch to exercise the descriptor protocol and get the true callable.

From the source code:

It can be called either on the class (e.g. C.f()) or on an instance (e.g. C().f()); the instance is ignored except for its class.

But not directly from inside the class while it is being defined.

But as one commenter mentioned, this is not really a "Pythonic" design at all. Just use a module level function instead.

Format with Currency format string

=Format(Fields!Price.Value, "C")

It will give you 2 decimal places with "$" prefixed.

You can find other format strings on MSDN: Adding Style and Formatting to a ReportViewer Report

Note: The MSDN article has been archived to the "VS2005_General" document, which is no longer directly accessible online. Here is the excerpt of the formatting strings referenced:

Formatting Numbers

The following table lists common .NET Framework number formatting strings.

Format string, Name

C or c Currency

D or d Decimal

E or e Scientific

F or f Fixed-point

G or g General

N or n Number

P or p Percentage

R or r Round-trip

X or x Hexadecimal

You can modify many of the format strings to include a precision specifier that defines the number of digits to the right of the

decimal point. For example, a formatting string of D0 formats the number so that it has no digits after the decimal point. You

can also use custom formatting strings, for example, #,###.

Formatting Dates

The following table lists common .NET Framework date formatting strings.

Format string, Name

d Short date

D Long date

t Short time

T Long time

f Full date/time (short time)

F Full date/time (long time)

g General date/time (short time)

G General date/time (long time)

M or m Month day

R or r RFC1123 pattern

Y or y Year month

You can also a use custom formatting strings; for example, dd/MM/yy. For more information about .NET Framework formatting strings, see Formatting Types.

If you're generating the shell string within Python 2 or Python 3, the following may help to quote the arguments:

#!/usr/bin/env python

from __future__ import print_function

try:  # py3
    from shlex import quote as shlex_quote
except ImportError:  # py2
    from pipes import quote as shlex_quote

s = """foo ain't "bad" so there!"""

print(s)
print(" ".join([shlex_quote(t) for t in s.split()]))

This will output:

foo ain't "bad" so there!
foo 'ain'"'"'t' '"bad"' so 'there!'

According to the PHP.net manual:

If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use isset() to check a variable is registered in $_SESSION.

The three options that come to mind:

1st) End void loop() with while(1)... or equally as good... while(true)

void loop(){
    //the code you want to run once here, 
    //e.g., If (blah == blah)...etc.

    while(1)        //last line of main loop
}

This option runs your code once and then kicks the Ard into an endless "invisible" loop. Perhaps not the nicest way to go, but as far as outside appearances, it gets the job done.
The Ard will continue to draw current while it spins itself in an endless circle... perhaps one could set up a sort of timer function that puts the Ard to sleep after so many seconds, minutes, etc., of looping... just a thought... there are certainly various sleep libraries out there... see e.g., Monk, Programming Arduino: Next Steps, pgs., 85-100 for further discussion of such.

2nd) Create a "stop main loop" function with a conditional control structure that makes its initial test fail on a second pass.
This often requires declaring a global variable and having the "stop main loop" function toggle the value of the variable upon termination. E.g.,

boolean stop_it = false;         //global variable

void setup(){
    Serial.begin(9600); 
    //blah...
}

boolean stop_main_loop(){        //fancy stop main loop function

    if(stop_it == false){   //which it will be the first time through

        Serial.println("This should print once.");

       //then do some more blah....you can locate all the
       // code you want to run once here....eventually end by 
       //toggling the "stop_it" variable ... 
    }
    stop_it = true; //...like this
    return stop_it;   //then send this newly updated "stop_it" value
                     // outside the function
}

void loop{ 

    stop_it = stop_main_loop();     //and finally catch that updated 
                                    //value and store it in the global stop_it 
                                    //variable, effectively 
                                    //halting the loop  ...
}

Granted, this might not be especially pretty, but it also works.
It kicks the Ard into another endless "invisible" loop, but this time it's a case of repeatedly checking the if(stop_it == false) condition in stop_main_loop() which of course fails to pass every time after the first time through.

3rd) One could once again use a global variable but use a simple if (test == blah){} structure instead of a fancy "stop main loop" function.

boolean start = true;                  //global variable

void setup(){

      Serial.begin(9600);
}

void loop(){

      if(start == true){           //which it will be the first time through



           Serial.println("This should print once.");       

           //the code you want to run once here, 
           //e.g., more If (blah == blah)...etc.

     }

start = false;                //toggle value of global "start" variable
                              //Next time around, the if test is sure to fail.
}

There are certainly other ways to "stop" that pesky endless main loop but these three as well as those already mentioned should get you started.

import sys
sys.setrecursionlimit(1500)

def fib(n, sum):
    if n < 1:
        return sum
    else:
        return fib(n-1, sum+n)

c = 998
print(fib(c, 0))

Here's how to list local branches that do not have a remote branch in origin with the same name:

git branch | sed 's|* |  |' | sort > local
git branch -r | sed 's|origin/||' | sort > remote
comm -23 local remote

I was having a similar problem that I could not resolve for a long time on my new server. In addition to palacsint's answer, a good question to ask is: are you using Apache 2.4? In Apache 2.4 there is a different mechanism for setting the permissions that do not work when done using the above configuration, so I used the solution explained in this blog post.

Basically, what I needed to do was convert my config file from:

Alias /demo /usr/demo/html

<Directory "/usr/demo/html">
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    allow from all

</Directory>

to:

Alias /demo /usr/demo/html

<Directory "/usr/demo/html">
    Options FollowSymLinks
    AllowOverride None
    Require all granted
</Directory>

Note how the Order and allow lines have been replaced by Require all granted

here's how I promote all worksheet names to global names. YMMV

For Each wsh In ActiveWorkbook.Worksheets
For Each n In wsh.Names
    ' Get unqualified range name
    Dim s As String
    s = Split(n.Name, "!")(UBound(Split(n.Name, "!")))
    ' Add to "Workbook" scope
    n.RefersToRange.Name = s
    ' Remove from "Worksheet" scope
    Call n.Delete
Next n
Next wsh

ES6 style allows you to use new features, such as super keyword. super keyword it's all about parent class context, when you are using ES6 classes syntax. As a very simple example, checkout:

class Foo {
    static classMethod() {
        return 'hello';
    }
}

class Bar extends Foo {
    static classMethod() {
        return super.classMethod() + ', too';
    }
}
Bar.classMethod(); // 'hello, too'

Also, you can use super to call parent constructor:

class Foo {}

class Bar extends Foo {
    constructor(num) {
        let tmp = num * 2; // OK
        this.num = num; // ReferenceError
        super();
        this.num = num; // OK
    }
}

And of course you can use it to access parent class properties super.prop. So, use ES6 and be happy.

It's really easy to do this, simply send the file via an XHR request inside of the file input's onchange handler.

<input id="myFileInput" type="file" accept="image/*;capture=camera">

var myInput = document.getElementById('myFileInput');

function sendPic() {
    var file = myInput.files[0];

    // Send file here either by adding it to a `FormData` object 
    // and sending that via XHR, or by simply passing the file into 
    // the `send` method of an XHR instance.
}

myInput.addEventListener('change', sendPic, false);

Consider an array A of N x 2 dimensions. To add one more row, use the following.

A.loc[A.shape[0]] = [3,4]

Put this code in the <head></head> tags:

<script type="text/javascript" src="http://code.jquery.com/jquery-1.10.0.min.js"></script>

CSS tricks have a good solution to target IE 11:

http://css-tricks.com/ie-10-specific-styles/

The .NET and Trident/7.0 are unique to IE so can be used to detect IE version 11.

The code then adds the User Agent string to the html tag with the attribute 'data-useragent', so IE 11 can be targeted specifically...

I tend to just load the entire buffer as a raw memory chunk into memory and do the parsing on my own. That way I have best control over what the standard lib does on multiple platforms.

This is a stub I use for this. you may also want to check the error-codes for fseek, ftell and fread. (omitted for clarity).

char * buffer = 0;
long length;
FILE * f = fopen (filename, "rb");

if (f)
{
  fseek (f, 0, SEEK_END);
  length = ftell (f);
  fseek (f, 0, SEEK_SET);
  buffer = malloc (length);
  if (buffer)
  {
    fread (buffer, 1, length, f);
  }
  fclose (f);
}

if (buffer)
{
  // start to process your data / extract strings here...
}

Two suggestions:

• Use a HashSet instead of an ArrayList. This will speed up the contains() checks considerably if you have a long list

• Make sure Customer.equals() and Customer.hashCode() are implemented properly, i.e. they should be based on the combined values of the underlying fields in the customer object.

If you're calling ASP.NET Web Services from the client-side you have to use application/json for it to work. I believe this is the same for the jQuery and Ext frameworks.

PLEASE do not use object as a class name:

public class MyObject //better to choose an appropriate name
{
    string id;
    DateTime date;
    public string ID
    {
       get { return id; }
       set { id = value; }
    }
    public DateTime Date
    {
       get { return date; }
       set { date = value; }
    }
}

You should implement INotifyPropertyChanged for this class and of course call it on the Property setter. Otherwise changes are not reflected in your ui.

Your Viewmodel class/ dialogbox class should have a Property of your MyObject list. ObservableCollection<MyObject> is the way to go:

public ObservableCollection<MyObject> MyList
{
     get...
     set...
}

In your xaml you should set the Itemssource to your collection of MyObject. (the Datacontext have to be your dialogbox class!)

<DataGrid ItemsSource="{Binding Source=MyList}"  AutoGenerateColumns="False">
   <DataGrid.Columns>                
     <DataGridTextColumn Header="ID" Binding="{Binding ID}"/>
     <DataGridTextColumn Header="Date" Binding="{Binding Date}"/>
   </DataGrid.Columns>
</DataGrid>

It's been quite some time but it's a core part of the stdlib and has dozens of potential methods so I think it's useful to have some benchmarks for the different suggestions and include the numpy method which can be by far the fastest.

import random
from timeit import timeit
import numpy as np

l = [random.random() for i in range(10**4)]
l[10**4 - 100] = 5

# method 1
def fun1(l:list, x:int, e = -1) -> int:
    return [[i for i,elem in enumerate(l) if elem == x] or [e]][0]

# method 2
def fun2(l:list, x:int, e = -1) -> int:
    for i,elem in enumerate(l):
        if elem == x:
            return i
    else:
        return e

# method 3
def fun3(l:list, x:int, e = -1) -> int:
    try:
        idx = l.index(x)
    except ValueError:
        idx = e
    return idx

# method 4
def fun4(l:list, x:int, e = -1) -> int:
    return l.index(x) if x in l else e

l2 = np.array(l)
# method 5
def fun5(l:list or np.ndarray, x:int, e = -1) -> int:
    res = np.where(np.equal(l, x))
    if res[0].any():
        return res[0][0]
    else:        
        return e


if __name__ == "__main__":
    print("Method 1:")
    print(timeit(stmt = "fun1(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 2:")
    print(timeit(stmt = "fun2(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 3:")
    print(timeit(stmt = "fun3(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 4:")
    print(timeit(stmt = "fun4(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 5, numpy given list:")
    print(timeit(stmt = "fun5(l, 5)", number = 1000, globals = globals()))
    print("")
    print("Method 6, numpy given np.ndarray:")
    print(timeit(stmt = "fun5(l2, 5)", number = 1000, globals = globals()))
    print("")

When run as main, this results in the following printout on my machine indicating time in seconds to complete 1000 trials of each function:

Method 1: 0.7502102799990098

Method 2: 0.7291318440002215

Method 3: 0.24142152300009911

Method 4: 0.5253471979995084

Method 5, numpy given list: 0.5045417560013448

Method 6, numpy given np.ndarray: 0.011147511999297421

Of course the question asks specifically about lists so the best solution is to use the try-except method, however the speed improvements (at least 20x here compared to try-except) offered by using the numpy data structures and operators instead of python data structures is significant and if building something on many arrays of data that is performance critical then the author should try to use numpy throughout to take advantage of the superfast C bindings. (CPython interpreter, other interpreter performances may vary)

Btw, the reason Method 5 is much slower than Method 6 is because numpy first has to convert the given list to it's own numpy array, so giving it a list doesn't break it it just doesn't fully utilise the speed possible.

There are 3 different things we are using here :

1. JPA : Java persistence api which provide specification for persisting, reading, managing data from your java object to relations in database.
2. Hibernate: There are various provider which implement jpa. Hibernate is one of them. So we have other provider as well. But if using jpa with spring it allows you to switch to different providers in future.
3. Spring Data JPA : This is another layer on top of jpa which spring provide to make your life easy.

So lets understand how spring data jpa and spring + hibernate works-

Spring Data JPA:

Let's say you are using spring + hibernate for your application. Now you need to have dao interface and implementation where you will be writing crud operation using SessionFactory of hibernate. Let say you are writing dao class for Employee class, tomorrow in your application you might need to write similiar crud operation for any other entity. So there is lot of boilerplate code we can see here.

Now Spring data jpa allow us to define dao interfaces by extending its repositories(crudrepository, jparepository) so it provide you dao implementation at runtime. You don't need to write dao implementation anymore.Thats how spring data jpa makes your life easy.

The API of java.io.File only supports getting the last modified time. And the Internet is very quiet on this topic as well.

Unless I missed something significant, the Java library as is (up to but not yet including Java 7) does not include this capability. So if you were desperate for this, one solution would be to write some C(++) code to call system routines and call it using JNI. Most of this work seems to be already done for you in a library called JNA, though.

You may still need to do a little OS specific coding in Java for this, though, as you'll probably not find the same system calls available in Windows and Unix/Linux/BSD/OS X.

Try this as the command string in Task Scheduler:

cmd /c yourscript.cmd > logall.txt

The headers only remain fixed when the UITableViewStyle property of the table is set to UITableViewStylePlain. If you have it set to UITableViewStyleGrouped, the headers will scroll up with the cells.

Workstation has some features that Player lacks, such as teams (groups of VMs connected by private LAN segments) and multi-level snapshot trees. It's aimed at power users and developers; they even have some hooks for using a debugger on the host to debug code in the VM (including kernel-level stuff). The core technology is the same, though.

Something along the lines of this?

<asp:TextBox id="txtUsername" runat="server" />

<asp:RegularExpressionValidator
    id="RegularExpressionValidator1"
    runat="server"
    ErrorMessage="Field not valid!"
    ControlToValidate="txtUsername"
    ValidationExpression="[0-9a-zA-Z]{6,}" />

use jQuery's $.getJSON

$.getJSON('mydata.json', function(data) {
    //do stuff with your data here
});

Stephen Toub wrote a great article on implementing global keyboard hooks in C#:

using System;
using System.Diagnostics;
using System.Windows.Forms;
using System.Runtime.InteropServices;

class InterceptKeys
{
    private const int WH_KEYBOARD_LL = 13;
    private const int WM_KEYDOWN = 0x0100;
    private static LowLevelKeyboardProc _proc = HookCallback;
    private static IntPtr _hookID = IntPtr.Zero;

    public static void Main()
    {
        _hookID = SetHook(_proc);
        Application.Run();
        UnhookWindowsHookEx(_hookID);
    }

    private static IntPtr SetHook(LowLevelKeyboardProc proc)
    {
        using (Process curProcess = Process.GetCurrentProcess())
        using (ProcessModule curModule = curProcess.MainModule)
        {
            return SetWindowsHookEx(WH_KEYBOARD_LL, proc,
                GetModuleHandle(curModule.ModuleName), 0);
        }
    }

    private delegate IntPtr LowLevelKeyboardProc(
        int nCode, IntPtr wParam, IntPtr lParam);

    private static IntPtr HookCallback(
        int nCode, IntPtr wParam, IntPtr lParam)

        if (nCode >= 0 && wParam == (IntPtr)WM_KEYDOWN)
        {
            int vkCode = Marshal.ReadInt32(lParam);
            Console.WriteLine((Keys)vkCode);
        }
        return CallNextHookEx(_hookID, nCode, wParam, lParam);
    }

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr SetWindowsHookEx(int idHook,
        LowLevelKeyboardProc lpfn, IntPtr hMod, uint dwThreadId);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool UnhookWindowsHookEx(IntPtr hhk);

    [DllImport("user32.dll", CharSet = CharSet.Auto, SetLastError = true)]
    private static extern IntPtr CallNextHookEx(IntPtr hhk, int nCode,

If you wanna use Javascript then you can use getElementsByName() method to select the input fields and to change the placeholder for each one... see the below code...

document.getElementsByName('Email')[0].placeholder='new text for email';
document.getElementsByName('First Name')[0].placeholder='new text for fname';
document.getElementsByName('Last Name')[0].placeholder='new text for lname';

Otherwise use jQuery:

$('input:text').attr('placeholder','Some New Text');

I feel most people have pip installed already with Python. On Windows, one way to check for pip is to open Command Prompt and typing in:

python -m pip

If you get Usage and Commands instructions then you have it installed. If python was not found though, then it needs to be added to the path. Alternatively you can run the same command from within the installation directory of python.

If all is good, then this command will install BeautifulSoup easily:

python -m pip install BeautifulSoup4

Screenshot:

N' now I see I need to upgrade my pip, which I just did :)

I used the following code, it's working!

using System.Data.OleDb;
using System.IO;
using System.Text.RegularExpressions;

private void btopen_Click(object sender, EventArgs e)
{
   try
   {
     OpenFileDialog openFileDialog1 = new OpenFileDialog();  //create openfileDialog Object
     openFileDialog1.Filter = "XML Files (*.xml; *.xls; *.xlsx; *.xlsm; *.xlsb) |*.xml; *.xls; *.xlsx; *.xlsm; *.xlsb";//open file format define Excel Files(.xls)|*.xls| Excel Files(.xlsx)|*.xlsx| 
     openFileDialog1.FilterIndex = 3;

     openFileDialog1.Multiselect = false;        //not allow multiline selection at the file selection level
     openFileDialog1.Title = "Open Text File-R13";   //define the name of openfileDialog
     openFileDialog1.InitialDirectory = @"Desktop"; //define the initial directory

     if (openFileDialog1.ShowDialog() == DialogResult.OK)        //executing when file open
     {
       string pathName = openFileDialog1.FileName;
       fileName = System.IO.Path.GetFileNameWithoutExtension(openFileDialog1.FileName);
       DataTable tbContainer = new DataTable();
       string strConn = string.Empty;
       string sheetName = fileName;

       FileInfo file = new FileInfo(pathName);
       if (!file.Exists) { throw new Exception("Error, file doesn't exists!"); }
       string extension = file.Extension;
       switch (extension)
       {
          case ".xls":
                   strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
                   break;
          case ".xlsx":
                   strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" + pathName + ";Extended Properties='Excel 12.0;HDR=Yes;IMEX=1;'";
                   break;
          default:
                   strConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + pathName + ";Extended Properties='Excel 8.0;HDR=Yes;IMEX=1;'";
                   break;
         }
         OleDbConnection cnnxls = new OleDbConnection(strConn);
         OleDbDataAdapter oda = new OleDbDataAdapter(string.Format("select * from [{0}$]", sheetName), cnnxls);
         oda.Fill(tbContainer);

         dtGrid.DataSource = tbContainer;
       }

     }
     catch (Exception)
     {
        MessageBox.Show("Error!");
     }
  }

Seem like the input type number does not support size attribute or it's not compatible along browsers, you can set it through CSS instead:

input[type=number]{
    width: 80px;
} 

Updated Fiddle

The simplest way to do this is:

git tag v1.0.0 f4ba1fc
git push origin --tags

with f4ba1fc being the beginning of the hash of the commit you want to tag and v1.0.0 being the version you want to tag.

I had the same issue when forking with 'python'; the main reason is that the search path is relative, if you don't call g++ as /usr/bin/g++, it will not be able to work out the canonical paths to call cc1plus.

git status | sed 's/^#\s*deleted:\s*//' | sed 's/^#.*//' | xargs git rm -rf

This is pretty simple here is an example

Add your command code here like:

if (cmd === `!dm`) {
 let dUser =
  message.guild.member(message.mentions.users.first()) ||
  message.guild.members.get(args[0]);
 if (!dUser) return message.channel.send("Can't find user!");
 if (!message.member.hasPermission('ADMINISTRATOR'))
  return message.reply("You can't you that command!");
 let dMessage = args.join(' ').slice(22);
 if (dMessage.length < 1) return message.reply('You must supply a message!');

 dUser.send(`${dUser} A moderator from WP Coding Club sent you: ${dMessage}`);

 message.author.send(
  `${message.author} You have sent your message to ${dUser}`
 );
}

this may not be accurate but its close enough for me

long size = 0;
object o = new object();
using (Stream s = new MemoryStream()) {
    BinaryFormatter formatter = new BinaryFormatter();
    formatter.Serialize(s, o);
    size = s.Length;
}

Example example;

This is a declaration of a variable named example of type Example. This will default-initialize the object which involves calling its default constructor. The object will have automatic storage duration which means that it will be destroyed when it goes out of scope.

Example* example;

This is a declaration of a variable named example which is a pointer to an Example. In this case, default-initialization leaves it uninitialized - the pointer is pointing nowhere in particular. There is no Example object here. The pointer object has automatic storage duration.

Example* example = new Example();

This is a declaration of a variable named example which is a pointer to an Example. This pointer object, as above, has automatic storage duration. It is then initialized with the result of new Example();. This new expression creates an Example object with dynamic storage duration and then returns a pointer to it. So the example pointer is now pointing to that dynamically allocated object. The Example object is value-initialized which will call a user-provided constructor if there is one or otherwise initialise all members to 0.

Example* example = new Example;

This is similar to the previous line. The difference is that the Example object is default-initialized, which will call the default constructor of Example (or leave it uninitialized if it is not of class type).

A dynamically allocated object must be deleted (probably with delete example;).

Go to the folder where Python is installed, e.g., in my case (Mac OS) it is installed in the Applications folder with the folder name 'Python 3.6'. Now double click on 'Install Certificates.command'. You will no longer face this error.

For those not running a mac, or having a different setup and can't find this file, the file merely runs:

pip install --upgrade certifi

Hope that helps someone :)

Here is what worked for me.

First of all I checked if M2_HOME variable is set env | grep M2_HOME. I've got nothing.

I knew I had Maven installed in the folder "/usr/local/apache-maven-3.2.2", so executing the following 3 steps solved the problem for me:

1. Set M2_HOME env variable

M2_HOME=/usr/local/apache-maven-3.2.2

2. Set M2 env variable

M2=$M2_HOME/bin

3. Update the PATH

export PATH=$M2:$PATH

As mentioned above you can save that sequence in the .bash_profile file if you want it to be executed automatically.

I know this is an OLD Question and there are multiple answers. How ever according to the docs and my experience on laravel below is the good "Eloquent way" of handling things

In your model, add a mutator/Getter like this

public function getCreatedAtTimeAttribute()
{
   return $this->created_at->toDateString();
}

Another way is to cast the columns in your model, populate the $cast array

$casts = [
   'created_at' => 'string'
]

The catch here is that you won't be able to use the Carbon on this model again since Eloquent will always cast the column into string

Hope it helps :)

This works as you wish:

<html>
<head>
    <style type="text/css"> 

ul
{ 
overflow-x:hidden;
white-space:nowrap; 
height: 1em;
width: 100%;
} 

li
{ 
display:inline; 
}       
    </style>
</head>
<body>

<ul> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li> 
<li>abcdefghijklmonpqrstuvwxyz</li>

For getting the practical view of converting .apk file into .java files just check out https://www.youtube.com/watch?v=-AX4NYE-9V8 video . you will get more benefited and understand clearly. It clearly demonstrates the steps you required if you are using mac OS.

The basic requirement for getting this done. 1. http://code.google.com/p/dex2jar/
2. http://jd.benow.ca/

You can iterate DataTable like this:

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

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

Magic Enum header-only library provides static reflection for enums (to string, from string, iteration) for C++17.

#include <magic_enum.hpp>

enum Color { RED = 2, BLUE = 4, GREEN = 8 };

Color color = Color::RED;
auto color_name = magic_enum::enum_name(color);
// color_name -> "RED"

std::string color_name{"GREEN"};
auto color = magic_enum::enum_cast<Color>(color_name)
if (color.has_value()) {
  // color.value() -> Color::GREEN
};

For more examples check home repository https://github.com/Neargye/magic_enum.

Where is the drawback?

This library uses a compiler-specific hack (based on __PRETTY_FUNCTION__ / __FUNCSIG__), which works on Clang >= 5, MSVC >= 15.3 and GCC >= 9.

Enum value must be in range [MAGIC_ENUM_RANGE_MIN, MAGIC_ENUM_RANGE_MAX].

• By default MAGIC_ENUM_RANGE_MIN = -128, MAGIC_ENUM_RANGE_MAX = 128.

• If need another range for all enum types by default, redefine the macro MAGIC_ENUM_RANGE_MIN and MAGIC_ENUM_RANGE_MAX.

• MAGIC_ENUM_RANGE_MIN must be less or equals than 0 and must be greater than INT16_MIN.

• MAGIC_ENUM_RANGE_MAX must be greater than 0 and must be less than INT16_MAX.

• If need another range for specific enum type, add specialization enum_range for necessary enum type.

  #include <magic_enum.hpp>
  
  enum number { one = 100, two = 200, three = 300 };
  
  namespace magic_enum {
  template <>
    struct enum_range<number> {
      static constexpr int min = 100;
      static constexpr int max = 300;
  };
  }
  

The easiest way is to put the declaration and definition in the same file, but it may cause over-sized excutable file. E.g.

class Foo
{
public:
template <typename T> void some_method(T t) {//...}
}

Also, it is possible to put template definition in the separate files, i.e. to put them in .cpp and .h files. All you need to do is to explicitly include the template instantiation to the .cpp files. E.g.

// .h file
class Foo
{
public:
template <typename T> void some_method(T t);
}

// .cpp file
//...
template <typename T> void Foo::some_method(T t) 
{//...}
//...

template void Foo::some_method<int>(int);
template void Foo::some_method<double>(double);

I've discovered the {{ request.get_host }} method.

We experienced these errors intermittently after upgraded from 11g to 12c and our java was on 1.6.

The fix for us was to upgrade java and jdbc from 6 to 7

export JAVA_HOME='/usr/java1.7'

export CLASSPATH=/u01/app/oracle/product/12.1.0/dbhome_1/jdbc/libojdbc7.jar:$CLASSPATH 

Several days later, still intermittent connection resets.

We ended up removing all the java 7 above. Java 6 was fine. The problem was fixed by adding this to our user bash_profile.

Our groovy scripts that were experiencing the error were using /dev/random on our batch VM server. Below forced java and groovy to use /dev/urandom.

export JAVA_OPTS=" $JAVA_OPTS -Djava.security.egd=file:///dev/urandom "

It would be nice if CheckStyle could verify that the serialVersionUID on a class that implements Serializable has a good value, i.e. that it matches what the serial version id generator would produce. If you have a project with lots of serializable DTOs, for example, remembering to delete the existing serialVersionUID and regenerate it is a pain, and currently the only way (that I know of) to verify this is to regenerate for each class and compare to the old one. This is very very painful.

srand(time(NULL));

int nRandonNumber = rand()%((nMax+1)-nMin) + nMin;
printf("%d\n",nRandonNumber);

I think in this case you want something like this:

$(window).resize(resize=function resize(){ some code...}

Now u can call resize() within some other nested functions:

$(window).scroll(function(){ resize();}

As mentiond by Ryan it's doing exactly what the documentation says.

From DOS times, current disk, and current path are distinguished. \ is the root path, but for the CURRENT DISK.

For every "disk" there is a separate "current path". If you change the disk using cd D: you do not change the current path to D:\, but to: "D:\whatever\was\the\last\path\accessed\on\this\disk"...

So, in windows, a literal @"\x" means: "CURRENTDISK:\x". Hence Path.Combine(@"C:\x", @"\y") has as second parameter a root path, not a relative, though not in a known disk... And since it is not known which might be the «current disk», python returns "\\y".

>cd C:
>cd \mydironC\apath
>cd D:
>cd \mydironD\bpath
>cd C:
>cd
>C:\mydironC\apath

Shows the latest file with human readable timestamp:

find . -type f -printf '%TY-%Tm-%Td %TH:%TM: %Tz %p\n'| sort -n | tail -n1

Result looks like this:

2015-10-06 11:30: +0200 ./foo/bar.txt

To show more files, replace -n1 with a higher number

Try following solution and let me know in case of any issues:

driver.get('https://example.com/')
driver.switchTo().alert().sendKeys("username" + Keys.TAB + "password");
driver.switchTo().alert().accept();

This is working fine for me

I had a requirement to register user. In that case I need to check whether that username is already present in the database or not. I have tried the below in C# windows form application(EntityFramework) and it worked.

 var result = incomeExpenseManagementDB.Users.FirstOrDefault(x => x.userName == registerUserView.uNameText);
  if (result == null) {
      register.registerUser(registerUserView.fnameText, registerUserView.lnameText, registerUserView.eMailText, registerUserView.mobileText, registerUserView.bDateText, registerUserView.uNameText, registerUserView.pWordText);
  } else {
      MessageBox.Show("User Alreay Exist. Try with Different Username");
  }

• The main entry point of the HttpClient API is the HttpClient interface.
• The most essential function of HttpClient is to execute HTTP methods.
• Execution of an HTTP method involves one or several HTTP request / HTTP response exchanges, usually handled internally by HttpClient.

• CloseableHttpClient is an abstract class which is the base implementation of HttpClient that also implements java.io.Closeable.

• Here is an example of request execution process in its simplest form:

  CloseableHttpClient httpclient = HttpClients.createDefault();
  HttpGet httpget = new HttpGet("http://localhost/");
  CloseableHttpResponse response = httpclient.execute(httpget);
  try {
      //do something
  } finally {
      response.close();
  }

• HttpClient resource deallocation: When an instance CloseableHttpClient is no longer needed and is about to go out of scope the connection manager associated with it must be shut down by calling the CloseableHttpClient#close() method.

  CloseableHttpClient httpclient = HttpClients.createDefault();
  try {
      //do something
  } finally {
      httpclient.close();
  }

see the Reference to learn fundamentals.

@Scadge Since Java 7, Use of try-with-resources statement ensures that each resource is closed at the end of the statement. It can be used both for the client and for each response

try(CloseableHttpClient httpclient = HttpClients.createDefault()){

    // e.g. do this many times
    try (CloseableHttpResponse response = httpclient.execute(httpget)) {
    //do something
    }

    //do something else with httpclient here
}

It's all about the key bindings which one can simply achieve from .vimrc configurations. As far as clipboard is concerned you can use :set clipboard unnamed and the yank from vim will go to system clipboard. Anyways, whichever one you end up using I suggest using this vimrc config , it contains a whole lot of plugins and bindings which will make your experience smooth.

From what I understand, you struggle with what to put into your template.

I'll show an example:

<ul>
    {% for guest in guests %}
    <li>{{ guest.name }} <a href="{{ path('your_delete_route_name',{'id': guest.id}) }}">[[DELETE]]</a></li>
    {% endfor %}
</ul>

Now what happens is it iterates over every object within guests (you'll have to rename this if your object collection is named otherwise!), shows the name and places the correct link. The route name might be different.

API 23 Android 6.0

For all the Kotlin users out there:

context?.let {
    val color = ContextCompat.getColor(it, R.color.colorPrimary)
    // ...
}

You can use the below code in the onclick listener of edittext

  TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
    new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay,
                              int minute) {

            tv_time.setText(hourOfDay + ":" + minute);
        }
    }, hour, minute, false);
     timePickerDialog.show();

You can see the full code at Android timepicker example

Suggestion 1

When you add an object to $stateProvider.state that object is then passed with the state. So you can add additional properties which you can read later on when needed.

Example route configuration

$stateProvider
.state('public', {
    abstract: true,
    module: 'public'
})
.state('public.login', {
    url: '/login',
    module: 'public'
})
.state('tool', {
    abstract: true,
    module: 'private'
})
.state('tool.suggestions', {
    url: '/suggestions',
    module: 'private'
});

The $stateChangeStart event gives you acces to the toState and fromState objects. These state objects will contain the configuration properties.

Example check for the custom module property

$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
    if (toState.module === 'private' && !$cookies.Session) {
        // If logged out and transitioning to a logged in page:
        e.preventDefault();
        $state.go('public.login');
    } else if (toState.module === 'public' && $cookies.Session) {
        // If logged in and transitioning to a logged out page:
        e.preventDefault();
        $state.go('tool.suggestions');
    };
});

I didn't change the logic of the cookies because I think that is out of scope for your question.

Suggestion 2

You can create a Helper to get you this to work more modular.

Value publicStates

myApp.value('publicStates', function(){
    return {
      module: 'public',
      routes: [{
        name: 'login', 
        config: { 
          url: '/login'
        }
      }]
    };
});

Value privateStates

myApp.value('privateStates', function(){
    return {
      module: 'private',
      routes: [{
        name: 'suggestions', 
        config: { 
          url: '/suggestions'
        }
      }]
    };
});

The Helper

myApp.provider('stateshelperConfig', function () {
  this.config = {
    // These are the properties we need to set
    // $stateProvider: undefined
    process: function (stateConfigs){
      var module = stateConfigs.module;
      $stateProvider = this.$stateProvider;
      $stateProvider.state(module, {
        abstract: true,
        module: module
      });
      angular.forEach(stateConfigs, function (route){
        route.config.module = module;
        $stateProvider.state(module + route.name, route.config);
      });
    }
  };

  this.$get = function () {
    return {
      config: this.config
    };
  };
});

Now you can use the helper to add the state configuration to your state configuration.

myApp.config(['$stateProvider', '$urlRouterProvider', 
    'stateshelperConfigProvider', 'publicStates', 'privateStates',
  function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
    helper.config.$stateProvider = $stateProvider;
    helper.process(publicStates);
    helper.process(privateStates);
}]);

This way you can abstract the repeated code, and come up with a more modular solution.

Note: the code above isn't tested

In order to create an instance of a generic type in a function you must constrain it with the "new" flag.

public static string GetAllItems<T>(...) where T : new()

However that will only work when you want to call the constructor which has no parameters. Not the case here. Instead you'll have to provide another parameter which allows for the creation of object based on parameters. The easiest is a function.

public static string GetAllItems<T>(..., Func<ListItem,T> del) {
  ...
  List<T> tabListItems = new List<T>();
  foreach (ListItem listItem in listCollection) 
  {
    tabListItems.Add(del(listItem));
  }
  ...
}

You can then call it like so

GetAllItems<Foo>(..., l => new Foo(l));

Based on your question history, you're using JSF 2.x. So, here's a JSF 2.x targeted answer. In JSF 1.x you would be forced to wrap item values/labels in ugly SelectItem instances. This is fortunately not needed anymore in JSF 2.x.

Basic example

To answer your question directly, just use <f:selectItems> whose value points to a List<T> property which you preserve from the DB during bean's (post)construction. Here's a basic kickoff example assuming that T actually represents a String.

<h:selectOneMenu value="#{bean.name}">
    <f:selectItems value="#{bean.names}" />
</h:selectOneMenu>

with

@ManagedBean
@RequestScoped
public class Bean {

    private String name;
    private List<String> names; 

    @EJB
    private NameService nameService;

    @PostConstruct
    public void init() {
        names = nameService.list();
    }

    // ... (getters, setters, etc)
}

Simple as that. Actually, the T's toString() will be used to represent both the dropdown item label and value. So, when you're instead of List<String> using a list of complex objects like List<SomeEntity> and you haven't overridden the class' toString() method, then you would see com.example.SomeEntity@hashcode as item values. See next section how to solve it properly.

Also note that the bean for <f:selectItems> value does not necessarily need to be the same bean as the bean for <h:selectOneMenu> value. This is useful whenever the values are actually applicationwide constants which you just have to load only once during application's startup. You could then just make it a property of an application scoped bean.

<h:selectOneMenu value="#{bean.name}">
    <f:selectItems value="#{data.names}" />
</h:selectOneMenu>

Complex objects as available items

Whenever T concerns a complex object (a javabean), such as User which has a String property of name, then you could use the var attribute to get hold of the iteration variable which you in turn can use in itemValue and/or itemLabel attribtues (if you omit the itemLabel, then the label becomes the same as the value).

Example #1:

<h:selectOneMenu value="#{bean.userName}">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user.name}" />
</h:selectOneMenu>

with

private String userName;
private List<User> users;

@EJB
private UserService userService;

@PostConstruct
public void init() {
    users = userService.list();
}

// ... (getters, setters, etc)

Or when it has a Long property id which you would rather like to set as item value:

Example #2:

<h:selectOneMenu value="#{bean.userId}">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user.id}" itemLabel="#{user.name}" />
</h:selectOneMenu>

with

private Long userId;
private List<User> users;

// ... (the same as in previous bean example)

Complex object as selected item

Whenever you would like to set it to a T property in the bean as well and T represents an User, then you would need to bake a custom Converter which converts between User and an unique string representation (which can be the id property). Do note that the itemValue must represent the complex object itself, exactly the type which needs to be set as selection component's value.

<h:selectOneMenu value="#{bean.user}" converter="#{userConverter}">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>

with

private User user;
private List<User> users;

// ... (the same as in previous bean example)

and

@ManagedBean
@RequestScoped
public class UserConverter implements Converter {

    @EJB
    private UserService userService;

    @Override
    public Object getAsObject(FacesContext context, UIComponent component, String submittedValue) {
        if (submittedValue == null || submittedValue.isEmpty()) {
            return null;
        }

        try {
            return userService.find(Long.valueOf(submittedValue));
        } catch (NumberFormatException e) {
            throw new ConverterException(new FacesMessage(String.format("%s is not a valid User ID", submittedValue)), e);
        }
    }

    @Override
    public String getAsString(FacesContext context, UIComponent component, Object modelValue) {
        if (modelValue == null) {
            return "";
        }

        if (modelValue instanceof User) {
            return String.valueOf(((User) modelValue).getId());
        } else {
            throw new ConverterException(new FacesMessage(String.format("%s is not a valid User", modelValue)), e);
        }
    }

}

(please note that the Converter is a bit hacky in order to be able to inject an @EJB in a JSF converter; normally one would have annotated it as @FacesConverter(forClass=User.class), but that unfortunately doesn't allow @EJB injections)

Don't forget to make sure that the complex object class has equals() and hashCode() properly implemented, otherwise JSF will during render fail to show preselected item(s), and you'll on submit face Validation Error: Value is not valid.

public class User {

    private Long id;

    @Override
    public boolean equals(Object other) {
        return (other != null && getClass() == other.getClass() && id != null)
            ? id.equals(((User) other).id)
            : (other == this);
    }

    @Override
    public int hashCode() {
        return (id != null) 
            ? (getClass().hashCode() + id.hashCode())
            : super.hashCode();
    }

}

Complex objects with a generic converter

Head to this answer: Implement converters for entities with Java Generics.

Complex objects without a custom converter

The JSF utility library OmniFaces offers a special converter out the box which allows you to use complex objects in <h:selectOneMenu> without the need to create a custom converter. The SelectItemsConverter will simply do the conversion based on readily available items in <f:selectItem(s)>.

<h:selectOneMenu value="#{bean.user}" converter="omnifaces.SelectItemsConverter">
    <f:selectItems value="#{bean.users}" var="user" itemValue="#{user}" itemLabel="#{user.name}" />
</h:selectOneMenu>

Do search with LEFT OUTER JOIN. I don't know if MySQL allows inline VALUES in join clauses but you can have predefined table for this purposes.

You can also use ng-pattern and I feel that will be a best practice. Similarly try to use ng-message. Please look the ng-pattern attribute on the following html. The code snippet is partial but hope you understand it.

angular.module('myApp', ['ngMessages']);
angular.module("myApp.controllers",[]).controller("registerCtrl", function($scope, Client) {
  $scope.ph_numbr = /^(\+?(\d{1}|\d{2}|\d{3})[- ]?)?\d{3}[- ]?\d{3}[- ]?\d{4}$/;
});

<form class="form-horizontal" role="form" method="post" name="registration" novalidate>
  <div class="form-group" ng-class="{ 'has-error' : (registration.phone.$invalid || registration.phone.$pristine)}">
    <label for="inputPhone" class="col-sm-3 control-label">Phone :</label>
    <div class="col-sm-9">
      <input type="number" class="form-control" ng-pattern="ph_numbr"  id="inputPhone" name="phone" placeholder="Phone" ng-model="user.phone" ng-required="true">
      <div class="help-block" ng-messages="registration.phone.$error">
        <p ng-message="required">Phone number is required.</p>
        <p ng-message="pattern">Phone number is invalid.</p>
      </div>
    </div>
  </div>
</form>

I'd use request for this:

request('http://google.com/doodle.png').pipe(fs.createWriteStream('doodle.png'))

Or if you don't need to save to a file first, and you just need to read the CSV into memory, you can do the following:

var request = require('request');
request.get('http://www.whatever.com/my.csv', function (error, response, body) {
    if (!error && response.statusCode == 200) {
        var csv = body;
        // Continue with your processing here.
    }
});

etc.

Create a HttpRequestMessage, set the Method to GET, set your headers and then use SendAsync instead of GetAsync.

var client = new HttpClient();
var request = new HttpRequestMessage() {
    RequestUri = new Uri("http://www.someURI.com"),
    Method = HttpMethod.Get,
};
request.Headers.Accept.Add(new MediaTypeWithQualityHeaderValue("text/plain"));
var task = client.SendAsync(request)
    .ContinueWith((taskwithmsg) =>
    {
        var response = taskwithmsg.Result;

        var jsonTask = response.Content.ReadAsAsync<JsonObject>();
        jsonTask.Wait();
        var jsonObject = jsonTask.Result;
    });
task.Wait();

In order to start an activity which should return result to the calling activity, you should do something like below. You should pass the requestcode as shown below in order to identify that you got the result from the activity you started.

startActivityForResult(new Intent(“YourFullyQualifiedClassName”),requestCode);

In the activity you can make use of setData() to return result.

Intent data = new Intent();
String text = "Result to be returned...."
//---set the data to pass back---
data.setData(Uri.parse(text));
setResult(RESULT_OK, data);
//---close the activity---
finish();

So then again in the first activity you write the below code in onActivityResult()

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == request_Code) {
        if (resultCode == RESULT_OK) {
            String returnedResult = data.getData().toString();
            // OR
            // String returnedResult = data.getDataString();
        }
    }
}

EDIT based on your comment: If you want to return three strings, then follow this by making use of key/value pairs with intent instead of using Uri.

Intent data = new Intent();
data.putExtra("streetkey","streetname");
data.putExtra("citykey","cityname");
data.putExtra("homekey","homename");
setResult(RESULT_OK,data);
finish();

Get them in onActivityResult like below:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == request_Code) {
        if (resultCode == RESULT_OK) {
            String street = data.getStringExtra("streetkey");
            String city = data.getStringExtra("citykey");
            String home = data.getStringExtra("homekey");
        }
    }
}

The Python Magic library provides the functionality you need.

You can install the library with pip install python-magic and use it as follows:

>>> import magic

>>> magic.from_file('iceland.jpg')
'JPEG image data, JFIF standard 1.01'

>>> magic.from_file('iceland.jpg', mime=True)
'image/jpeg'

>>> magic.from_file('greenland.png')
'PNG image data, 600 x 1000, 8-bit colormap, non-interlaced'

>>> magic.from_file('greenland.png', mime=True)
'image/png'

The Python code in this case is calling to libmagic beneath the hood, which is the same library used by the *NIX file command. Thus, this does the same thing as the subprocess/shell-based answers, but without that overhead.

From Netbeans 8.1 - there is an "Import from ZIP" option.

Go to Main Menu -> File -> Import Project -> from ZIP.

Browse your .ZIP file's location via Browse button.

If you have Java project depending on external Libraries, Netbeans will highlight & ask for "Resolving problems" in project, click on resolve, provide location in your file system containing required library files .e.g JARs etc & you will be good to go.

You will want to use the a ternary operator which acts as a shortened IF/Else statement:

echo '<option value="'.$value.'" '.(($value=='United States')?'selected="selected"':"").'>'.$value.'</option>';

The short answer is that ol elements are not legally allowed inside p elements.

To see why, let's go to the spec! If you can get comfortable with the HTML spec, it will answer many of your questions and curiosities. You want to know if an ol can live inside a p. So…

4.5.1 The p element:

Categories: Flow content, Palpable content.
Content model: Phrasing content.

4.5.5 The ol element:

Categories: Flow content.
Content model: Zero or more li and script-supporting elements.

The first part says that p elements can only contain phrasing content (which are “inline” elements like span and strong).

The second part says ols are flow content (“block” elements like p and div). So they can't be used inside a p.

ols and other flow content can be used in in some other elements like div:

4.5.13 The div element:

Categories: Flow content, Palpable content.
Content model: Flow content.

It can depend, especially on whether your file will have the same number of items on each row or not. If it will, then you probably want a 2D matrix class of some sort, usually something like this:

class array2D { 
    std::vector<double> data;
    size_t columns;
public:
    array2D(size_t x, size_t y) : columns(x), data(x*y) {}

    double &operator(size_t x, size_t y) {
       return data[y*columns+x];
    }
};

Note that as it's written, this assumes you know the size you'll need up-front. That can be avoided, but the code gets a little larger and more complex.

In any case, to read the numbers and maintain the original structure, you'd typically read a line at a time into a string, then use a stringstream to read numbers from the line. This lets you store the data from each line into a separate row in your array.

If you don't know the size ahead of time or (especially) if different rows might not all contain the same number of numbers:

11 12 13
23 34 56 78

You might want to use a std::vector<std::vector<double> > instead. This does impose some overhead, but if different rows may have different sizes, it's an easy way to do the job.

std::vector<std::vector<double> > numbers;

std::string temp;

while (std::getline(infile, temp)) {
    std::istringstream buffer(temp);
    std::vector<double> line((std::istream_iterator<double>(buffer)),
                             std::istream_iterator<double>());

    numbers.push_back(line);
}

...or, with a modern (C++11) compiler, you can use brackets for line's initialization:

    std::vector<double> line{std::istream_iterator<double>(buffer),
                             std::istream_iterator<double>()};

I know my answer is late, but IMO this is the easiest way to toggle a Button 'enable' and button 'disable'

function toggleButtonState(button){

  //If button is enabled, -> Disable
  if (button.disabled === false) {
    button.disabled = true;

  //If button is disabled, -> Enable
  } else if (button.disabled === true) {
    button.disabled = false;
  }
}

            else 'away' 
        end as join_condition, 
        g.network,

You need to save your PHP script file in UTF-8 encoding, and leave the <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> in the HTML.

For text editor, I recommend Notepad++, because it can detect and display the actual encoding of the file (in the lower right corner of the editor), and you can convert it as well.

Save as a script named mv or mv.sh

#!/bin/bash
# mv.sh
dir="$2"
tmp="$2"; tmp="${tmp: -1}"
[ "$tmp" != "/" ] && dir="$(dirname "$2")"
[ -a "$dir" ] ||
mkdir -p "$dir" &&
mv "$@"

Or put at the end of your ~/.bashrc file as a function that replaces the default mv on every new terminal. Using a function allows bash keep it memory, instead of having to read a script file every time.

function mv ()
{
    dir="$2"
    tmp="$2"; tmp="${tmp: -1}"
    [ "$tmp" != "/" ] && dir="$(dirname "$2")"
    [ -a "$dir" ] ||
    mkdir -p "$dir" &&
    mv "$@"
}

These based on the submission of Chris Lutz.

When you set a percentage height on an element who's parent elements don't have heights set, the parent elements have a default

height: auto;

You are asking the browser to calculate a height from an undefined value. Since that would equal a null-value, the result is that the browser does nothing with the height of child elements.

Besides using a JavaScript solution you could use this deadly easy table method:

#parent3 {
    display: table;
    width: 100%;
}

#parent3 .between {
    display: table-row;
}

#parent3 .child {
    display: table-cell;
}

• Example 1: Not working
• Example 2: Fix height
• Example 3: Table method

But: Bare in mind, that the table method only works properly in all modern Browsers and the Internet Explorer 8 and higher. As Fallback you could use JavaScript.

The documentation for this at the MySQL site is woefully out of date and riddled with foot-guns (such as interactive_timeout). Issuing FLUSH TABLES WITH READ LOCK as part of your export of the master generally only makes sense when coordinated with a storage/filesystem snapshot such as LVM or zfs.

If you are going to use mysqldump, you should rely instead on the --master-data option to guard against human error and release the locks on the master as quickly as possible.

Assume the master is 192.168.100.50 and the slave is 192.168.100.51, each server has a distinct server-id configured, the master has binary logging on and the slave has read-only=1 in my.cnf

To stage the slave to be able to start replication just after importing the dump, issue a CHANGE MASTER command but omit the log file name and position:

slaveserver> CHANGE MASTER TO MASTER_HOST='192.168.100.50', MASTER_USER='replica', MASTER_PASSWORD='asdmk3qwdq1';

Issue the GRANT on the master for the slave to use:

masterserver> GRANT REPLICATION SLAVE ON *.* TO 'replica'@'192.168.100.51' IDENTIFIED BY 'asdmk3qwdq1';

Export the master (in screen) using compression and automatically capturing the correct binary log coordinates:

mysqldump --master-data --all-databases --flush-privileges | gzip -1 > replication.sql.gz

Copy the replication.sql.gz file to the slave and then import it with zcat to the instance of MySQL running on the slave:

zcat replication.sql.gz | mysql

Start replication by issuing the command to the slave:

slaveserver> START SLAVE;

Optionally update the /root/.my.cnf on the slave to store the same root password as the master.

If you are on 5.1+, it is best to first set the master's binlog_format to MIXED or ROW. Beware that row logged events are slow for tables which lack a primary key. This is usually better than the alternative (and default) configuration of binlog_format=statement (on master), since it is less likely to produce the wrong data on the slave.

If you must (but probably shouldn't) filter replication, do so with slave options replicate-wild-do-table=dbname.% or replicate-wild-ignore-table=badDB.% and use only binlog_format=row

This process will hold a global lock on the master for the duration of the mysqldump command but will not otherwise impact the master.

If you are tempted to use mysqldump --master-data --all-databases --single-transaction (because you only using InnoDB tables), you are perhaps better served using MySQL Enterprise Backup or the open source implementation called xtrabackup (courtesy of Percona)

Want to format it automatically when you save the file???

then Goto Window > Preferences > Java > Editor > Save Actions

and configure your save actions.

Along with saving, you can format, Organize imports,add modifier ‘final’ where possible etc

String fields with the binary flag set will always be case sensitive. Should you need a case sensitive search for a non binary text field use this: SELECT 'test' REGEXP BINARY 'TEST' AS RESULT;

Putting the subquery in the WHERE clause and restricting it to n.control_number means it runs the subquery many times. This is called a correlated subquery, and it's often a performance killer.

It's better to run the subquery once, in the FROM clause, to get the max date per control number.

SELECT n.* 
FROM tblpm n 
INNER JOIN (
  SELECT control_number, MAX(date_updated) AS date_updated
  FROM tblpm GROUP BY control_number
) AS max USING (control_number, date_updated);

Starting with Cygwin 1.7.34, the recommended way to do this is to add a custom db_home setting to /etc/nsswitch.conf. A common wish when doing this is to make your Cygwin home directory equal to your Windows user profile directory. This setting will do that:

db_home: windows

Or, equivalently:

db_home: /%H

You need to use the latter form if you want some variation on this scheme, such as to segregate your Cygwin home files into a subdirectory of your Windows user profile directory:

db_home: /%H/cygwin

There are several other alternative schemes for the windows option plus several other % tokens you can use instead of %H or in addition to it. See the nsswitch.conf syntax description in the Cygwin User Guide for details.

If you installed Cygwin prior to 1.7.34 or have run its mkpasswd utility so that you have an /etc/passwd file, you can change your Cygwin home directory by editing your user's entry in that file. Your home directory is the second-to-last element on your user's line in /etc/passwd.¹

Whichever way you do it, this causes the HOME environment variable to be set during shell startup.²

See this FAQ item for more on the topic.

Footnotes:

1. Consider moving /etc/passwd and /etc/group out of the way in order to use the new SAM/AD-based mechanism instead.

2. While it is possible to simply set %HOME% via the Control Panel, it is officially discouraged. Not only does it unceremoniously override the above mechanisms, it doesn't always work, such as when running shell scripts via cron.

string intern() method is used to create an exact copy of heap string object in string constant pool. The string objects in the string constant pool are automatically interned but string objects in heap are not. The main use of creating interns is to save the memory space and to perform faster comparison of string objects.

In situations where the class under test can be modified and when it's desirable to avoid byte code manipulation, to keep things fast or to minimise third party dependencies, here is my take on the use of a factory to extract the new operation.

public class TestedClass {

    interface PojoFactory { Pojo getNewPojo(); }

    private final PojoFactory factory;

    /** For use in production - nothing needs to change. */
    public TestedClass() {
        this.factory = new PojoFactory() {
            @Override
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };
    }

    /** For use in testing - provide a pojo factory. */
    public TestedClass(PojoFactory factory) {
        this.factory = factory;
    }

    public void doSomething() {
        Pojo pojo = this.factory.getNewPojo();
        anythingCouldHappen(pojo);
    }
}

With this in place, your testing, asserts and verify calls on the Pojo object are easy:

public  void testSomething() {
    Pojo testPojo = new Pojo();
    TestedClass target = new TestedClass(new TestedClass.PojoFactory() {
                @Override
                public Pojo getNewPojo() {
                    return testPojo;
                }
            });
    target.doSomething();
    assertThat(testPojo.isLifeStillBeautiful(), is(true));
}

The only downside to this approach potentially arises if TestClass has multiple constructors which you'd have to duplicate with the extra parameter.

For SOLID reasons you'd probably want to put the PojoFactory interface onto the Pojo class instead, and the production factory as well.

public class Pojo {

    interface PojoFactory { Pojo getNewPojo(); }

    public static final PojoFactory productionFactory = 
        new PojoFactory() {
            @Override 
            public Pojo getNewPojo() {
                return new Pojo();
            }
        };

You can build DFA using simple modular arithmetics. We can interpret w which is a string of k-ary numbers using a following rule

V[0] = 0
V[i] = (S[i-1] * k) + to_number(str[i])

V[|w|] is a number that w is representing. If modify this rule to find w mod N, the rule becomes this.

V[0] = 0
V[i] = ((S[i-1] * k) + to_number(str[i])) mod N

and each V[i] is one of a number from 0 to N-1, which corresponds to each state in DFA. We can use this as the state transition.

See an example.

k = 2, N = 5

| V | (V*2 + 0) mod 5     | (V*2 + 1) mod 5     |
+---+---------------------+---------------------+
| 0 | (0*2 + 0) mod 5 = 0 | (0*2 + 1) mod 5 = 1 |
| 1 | (1*2 + 0) mod 5 = 2 | (1*2 + 1) mod 5 = 3 |
| 2 | (2*2 + 0) mod 5 = 4 | (2*2 + 1) mod 5 = 0 |
| 3 | (3*2 + 0) mod 5 = 1 | (3*2 + 1) mod 5 = 2 |
| 4 | (4*2 + 0) mod 5 = 3 | (4*2 + 1) mod 5 = 4 |

k = 3, N = 5

| V | 0 | 1 | 2 |
+---+---+---+---+
| 0 | 0 | 1 | 2 |
| 1 | 3 | 4 | 0 |
| 2 | 1 | 2 | 3 |
| 3 | 4 | 0 | 1 |
| 4 | 2 | 3 | 4 |

Now you can see a very simple pattern. You can actually build a DFA transition just write repeating numbers from left to right, from top to bottom, from 0 to N-1.

You can also use Requestify, a really cool and simple HTTP client I wrote for nodeJS + it supports caching.

Just do the following:

    var requestify = require('requestify');

    requestify.post('http://example.com', {
        hello: 'world'
    })
    .then(function(response) {
        // Get the response body (JSON parsed or jQuery object for XMLs)
        response.getBody();
    });

The answer provided by Joe Stefanelli is already correct.

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

If a class type is not defined, you'll get a compiler error if you try to use the class, so in that sense you should have to check.

If you have an instance, and you want to ensure it's not null, simply check for null:

if (value != null)
{
    // it's not null. 
}

Here are the differences that can help you understand the advantages of persist and save methods:

• First difference between save and persist is their return type. The return type of persist method is void while return type of save
  method is Serializable object.

• The persist() method doesn’t guarantee that the identifier value will be assigned to the persistent state immediately, the assignment might happen at flush time.

• The persist() method will not execute an insert query if it is called outside of transaction boundaries. While, the save() method returns an identifier so that an insert query is executed immediately to get the identifier, no matter if it are inside or outside of a transaction.

• The persist method is called outside of transaction boundaries, it is useful in long-running conversations with an extended Session context. On the other hand save method is not good in a long-running conversation with an extended Session context.

• Fifth difference between save and persist method in Hibernate: persist is supported by JPA, while save is only supported by Hibernate.

You can see the full working example from the post Difference between save and persist method in Hibernate

The only illegal characters are &, < and > (as well as " or ' in attributes, depending on which character is used to delimit the attribute value: attr="must use " here, ' is allowed" and attr='must use ' here, " is allowed').

They're escaped using XML entities, in this case you want & for &.

Really, though, you should use a tool or library that writes XML for you and abstracts this kind of thing away for you so you don't have to worry about it.

A simple modal pop up div or dialog box can be done by CSS properties and little bit of jQuery.The basic idea is simple:

So we need three divs:

    #hider
    {
        position:absolute;
        top: 0%;
        left: 0%;
        width:1600px;
        height:2000px;
        margin-top: -800px; /*set to a negative number 1/2 of your height*/
        margin-left: -500px; /*set to a negative number 1/2 of your width*/
        /*
        z- index must be lower than pop up box
       */
        z-index: 99;
       background-color:Black;
       //for transparency
       opacity:0.6;
    }

    #popup_box  
    {

    position:absolute;
        top: 50%;
        left: 50%;
        width:10em;
        height:10em;
        margin-top: -5em; /*set to a negative number 1/2 of your height*/
        margin-left: -5em; /*set to a negative number 1/2 of your width*/
        border: 1px solid #ccc;
        border:  2px solid black;
        z-index:100; 

    }

        $(document).ready(function () {
        //hide hider and popup_box
        $("#hider").hide();
        $("#popup_box").hide();

        //on click show the hider div and the message
        $("#showpopup").click(function () {
            $("#hider").fadeIn("slow");
            $('#popup_box').fadeIn("slow");
        });
        //on click hide the message and the
        $("#buttonClose").click(function () {

            $("#hider").fadeOut("slow");
            $('#popup_box').fadeOut("slow");
        });

        });

<div id="hider"></div>
<div id="popup_box">

    <a id="buttonClose">Close</a>

1. Ensure the database's backup mode is set to Simple (see here for an overview of the different modes). This will avoid SQL Server waiting for a transaction log backup before reusing space.

2. Use dbcc shrinkfile or Management Studio to shrink the log files.

Step #2 will do nothing until the backup mode is set.

Perhaps you wanted to #include<string>, not <string.h>. std::string also needs a namespace qualification, or an explicit using directive.

Best practice is to throw an error if the class is constructed.

Example:

/**
 * The Class FooUtilityService.
 */
final class FooUtilityService{

/**
* Instantiates a new FooUtilityService. Private to prevent instantiation
*/
private FooUtilityService() {

    // Throw an exception if this ever *is* called
    throw new AssertionError("Instantiating utility class.");
}

No, they're not the same. Aside from the escaping on the client-side that it provides, a prepared statement is compiled on the server-side once, and then can be passed different parameters at each execution. Which means you can do:

$sth = $db->prepare("SELECT * FROM table WHERE foo = ?");
$sth->execute(array(1));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);

$sth->execute(array(2));
$results = $sth->fetchAll(PDO::FETCH_ASSOC);

They generally will give you a performance improvement, although not noticeable on a small scale. Read more on prepared statements (MySQL version).

This can be a good option if you want python completion as well as other languages. https://github.com/Valloric/YouCompleteMe

The python completion is jedi based same as jedi-vim.

You can use a tool like the TrIDNet - File Identifier to look for the Magic Number and other telltales, if the file format is in it's database it may tell you what it is for.

However searching the definitions did not turn up anything for the string "FLDB", but it checks more than magic numbers so it is worth a try.

If you are using Linux File is a command that will do a similar task.

The other thing to try is if you have access to the program that generated this file, there may be DLL's or EXE's from the database software that may contain meta information about the dll's creator which could give you a starting point for looking for software that can read the file outside of the program that originally created the .db file.

You should set the option:

local-infile=1

into your [mysql] entry of my.cnf file or call mysql client with the --local-infile option:

mysql --local-infile -uroot -pyourpwd yourdbname

You have to be sure that the same parameter is defined into your [mysqld] section too to enable the "local infile" feature server side.

It's a security restriction.

LOAD DATA LOCAL INFILE '/softwares/data/data.csv' INTO TABLE tableName;

If it IS a foreach loop as you have described in the question, using $key => $value is fast and efficient.

You can see if it's really not set. Run the command set | grep TERM.

If not, you can set it like that: export TERM=xterm

I understand this question is for sql server 2012, but if the same scenario for SQL Server 2017 or SQL Azure you can use Trim directly as below:

UPDATE *tablename*
   SET *columnname* = trim(*columnname*);

If you are using PL/SQL you can also use DBMS_ASSERT it can sanitize your input so you can use it without worrying about SQL injections.

see this answer for instance: https://stackoverflow.com/a/21406499/1726419

You can try with

var result = DateTime.Now.ToString("yyyy-MM-d--HH-mm-ss");

Without overriding EF track system, you can also Detach the 'local' entry and attach your updated entry before saving :

// 
var local = _context.Set<YourEntity>()
    .Local
    .FirstOrDefault(entry => entry.Id.Equals(entryId));

// check if local is not null 
if (local != null)
{
    // detach
    _context.Entry(local).State = EntityState.Detached;
}
// set Modified flag in your entry
_context.Entry(entryToUpdate).State = EntityState.Modified;

// save 
_context.SaveChanges();

UPDATE: To avoid code redundancy, you can do an extension method :

public static void DetachLocal<T>(this DbContext context, T t, string entryId) 
    where T : class, IIdentifier 
{
    var local = context.Set<T>()
        .Local
        .FirstOrDefault(entry => entry.Id.Equals(entryId));
    if (!local.IsNull())
    {
        context.Entry(local).State = EntityState.Detached;
    }
    context.Entry(t).State = EntityState.Modified;
}

My IIdentifier interface has just an Id string property.

Whatever your Entity, you can use this method on your context :

_context.DetachLocal(tmodel, id);
_context.SaveChanges();

Use match instead, and the g flag.

str.match(/<b>(.*?)<\/b>/g);

There's whereIn():

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